I am trying to get int x equal to 5 (as seen in the setNum() method) but when it prints it gives me 0.

To run the code in setNum you have to call it. If you don't call it, the default value is 0.

To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

If I am not mistaken, it will be onunload event.

"Occurs when the application is about to be unloaded." - MSDN

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

Fix it by install metro-config of the latest version (0.57.0 for now) they had fixed the problem:

npm install metro-config

you can remove it later, after react-native guys update module versions

The easiest way is to change imdb.py setting allow_pickle=True to np.load at the line where imdb.py throws error.

More of an addendum. I did repro the experiment using the latest Java 8 JVM from IBM:

java version "1.8.0_191"
Java(TM) 2 Runtime Environment, Standard Edition (IBM build 1.8.0_191-b12 26_Oct_2018_18_45 Mac OS X x64(SR5 FP25))
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

And this shows very similar results:

0.374653912 s
n = 119860736
0.447778698 s
n = 119860736

(second results using 2 * i * i).

Interestingly enough, when running on the same machine, but using Oracle Java:

Java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

results are on average a bit slower:

0.414331815 s
n = 119860736
0.491430656 s
n = 119860736

Long story short: even the minor version number of HotSpot matter here, as subtle differences within the JIT implementation can have notable effects.

Happy Coding!

Works properly on Andorid 8.1:

Updated sample (without any deprecated code):

public NotificationBattery(Context context) {
    this.mCtx = context;

    mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID)
            .setContentTitle(context.getString(R.string.notification_title_battery))
            .setSmallIcon(R.drawable.ic_launcher)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
            .setChannelId(CHANNEL_ID)
            .setOnlyAlertOnce(true)
            .setPriority(NotificationCompat.PRIORITY_MAX)
            .setWhen(System.currentTimeMillis() + 500)
            .setGroup(GROUP)
            .setOngoing(true);

    mRemoteViews = new RemoteViews(context.getPackageName(), R.layout.notification_view_battery);

    initBatteryNotificationIntent();

    mBuilder.setContent(mRemoteViews);

    mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    if (AesPrefs.getBooleanRes(R.string.SHOW_BATTERY_NOTIFICATION, true)) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

                    NotificationManager.IMPORTANCE_DEFAULT);
            channel.setShowBadge(false);
            channel.setSound(null, null);
            mNotificationManager.createNotificationChannel(channel);
        }
    } else {
        mNotificationManager.cancel(Const.NOTIFICATION_CLIPBOARD);
    }
}

Old snipped (it's a different app - not related to the code above):

I'm using, Angular CLI: 8.1.2 Node: 12.14.1 OS: win32 x64

Strangely, this helped me

npm cache clean --force
npm uninstall @angular/cli

This is due to the series df[cat] containing elements that have varying data types e.g.(strings and/or floats). This could be due to the way the data is read, i.e. numbers are read as float and text as strings or the datatype was float and changed after the fillna operation.

In other words

pandas data type 'Object' indicates mixed types rather than str type

so using the following line:

df[cat] = le.fit_transform(df[cat].astype(str))

should help

I have had the same problem. There is an answer:

• 1.CTRL + ALT + SHIFT + S;
  2. Then go to "Modules";
  3. "Dependencies;
  4. Change "Module SDK".

Got it! Now u have Java 9!

I was able to respond with the following methods:

1-Install-Package log4net

2-Install-Package MicroKnights.Log4NetAdoNetAppender

3-Install-Package System.Data.SqlClient

First,I Create Database and Table with this Code:

CREATE DATABSE Log4netDb
CREATE TABLE [dbo].[Log] (
    [Id] [int] IDENTITY (1, 1) NOT NULL,
    [Date] [datetime] NOT NULL,
    [Thread] [varchar] (255) NOT NULL,
    [Level] [varchar] (50) NOT NULL,
    [Logger] [varchar] (255) NOT NULL,
    [Message] [varchar] (4000) NOT NULL,
    [Exception] [varchar] (2000) NULL
)

Second, I Create log4net.config File in program . This is a simple configuration with no customization on the log message:

<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="true">
  <!-- definition of the RollingLogFileAppender goes here -->
  <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/WebApp.log" />
    <appendToFile value="true" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="10MB" />
    <staticLogFileName value="true" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <layout type="log4net.Layout.PatternLayout">
      <!-- Format is [date/time] [log level] [thread] message-->
      <conversionPattern value="[%date] [%level] [%thread] %m%n" />
    </layout>
  </appender>
  <appender name="AdoNetAppender" type="MicroKnights.Logging.AdoNetAppender, MicroKnights.Log4NetAdoNetAppender">
    <bufferSize value="1" />
    <connectionType value="System.Data.SqlClient.SqlConnection, System.Data" />
    <connectionStringName value="log4net" />
    <connectionStringFile value="appsettings.json" />
    <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message]) VALUES (@log_date, @thread, @log_level, @logger, @message)" />
    <parameter>
      <parameterName value="@log_date" />
      <dbType value="DateTime" />
      <layout type="log4net.Layout.RawTimeStampLayout" />
    </parameter>
    <parameter>
      <parameterName value="@thread" />
      <dbType value="String" />
      <size value="255" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%thread" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@log_level" />
      <dbType value="String" />
      <size value="50" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%level" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@logger" />
      <dbType value="String" />
      <size value="255" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%logger" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@message" />
      <dbType value="String" />
      <size value="4000" />
      <layout type="log4net.Layout.PatternLayout">

      </layout>
    </parameter>
    <parameter>
      <parameterName value="@exception" />
      <dbType value="String" />
      <size value="2000" />
      <layout type="log4net.Layout.ExceptionLayout" />
    </parameter>
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="RollingLogFileAppender" />
    <appender-ref ref="AdoNetAppender" />
  </root>
</log4net>

Third, Replace code below with 'IHostBuilder' :

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
    .ConfigureLogging(logging =>
    {
        // clear default logging providers
        logging.ClearProviders();
        logging.AddConsole();  
        logging.AddDebug();
        logging.AddEventLog();
        // add more providers here
    })
    .UseStartup<Startup>();

Fourth, in appsettings.json insert this code:

{
  "connectionStrings": {
    "log4net": "Server=MICKO-PC;Database=Log4netDb;Trusted_Connection=True;MultipleActiveResultSets=true"
  }
}

At the end, Use these commands to enjoy logging in

public class ValuesController : Controller
{
    private static readonly ILog log = LogManager.GetLogger(typeof(ValuesController));
    
    [HttpPost]
    public async Task<IActionResult> Login(string userName, string password)
    {
        log.Info("Action start");
        
        // More code here ...
        log.Info("Action end");
    }
    
    // More code here...
} 

Good luck.

If you look at the exception stack trace it says that, it failed to convert from ABDeadlineType to DeadlineType. Because your repository is going to return you the objects of ABDeadlineType. How the spring-data-jpa will convert into the other one(DeadlineType). You should return the same type from repository and then have some intermediate util class to convert it into your model class.

public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {
    List<ABDeadlineType> findAllSummarizedBy();
}

Spring Boot 2.2.2 / Gradle:

Gradle (build.gradle):

implementation("com.fasterxml.jackson.datatype:jackson-datatype-jsr310")

Entity (User.class):

LocalDate dateOfBirth;

Code:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
User user = mapper.readValue(json, User.class);

How about passing it as dp injection into that class? in ConfigureServices:

services.Configure<MyOptions>(Configuration);

create class to hold json strings:

public class MyOptions
{
    public MyOptions()
    {

    }
    public string Option1 { get; set; }
    public string Option2 { get; set; }
}    

Add strings to json file:

"option1": "somestring",
"option2": "someothersecretstring"

In classes that need these strings, pass in as constructor:

public class SomeClass
{
 private readonly MyOptions _options;

    public SomeClass(IOptions<MyOptions> options)
    {
        _options = options.Value;           
    }    

 public void UseStrings()
 {
   var option1 = _options.Option1;
    var option2 = _options.Option2;
 //code
 }
}

When you create a new ASP.NET Core 2.0 application, this hook is included by default. In previous versions of EF Core and ASP.NET Core, the tools try to invoke Startup.ConfigureServices directly in order to obtain the application's service provider, but this pattern no longer works correctly in ASP.NET Core 2.0 applications. If you are upgrading an ASP.NET Core 1.x application to 2.0, you can modify your Program class to follow the new pattern.

Add Factory in .Net Core 2.x

public class BloggingContextFactory : IDesignTimeDbContextFactory<BloggingContext>
    {
        public BloggingContext CreateDbContext(string[] args)
        {
            var optionsBuilder = new DbContextOptionsBuilder<BloggingContext>();
            optionsBuilder.UseSqlite("Data Source=blog.db");

            return new BloggingContext(optionsBuilder.Options);
        }
    }

Give the same name in urls.py

 path('detail/<int:id>', views.detail, name="detail"),

I found a different way to handle this error. (the variables is according to the original question)

   JsonNode parsedNodes = mapper.readValue(jsonMessage , JsonNode.class);
        Response response = xmlMapper.enable(ACCEPT_EMPTY_STRING_AS_NULL_OBJECT,ACCEPT_SINGLE_VALUE_AS_ARRAY )
                .disable(FAIL_ON_UNKNOWN_PROPERTIES, FAIL_ON_IGNORED_PROPERTIES)
                .convertValue(parsedNodes, Response.class);

Pipes in Angular 2+ are a great way to transform and format data right from your templates.

Pipes allow us to change data inside of a template; i.e. filtering, ordering, formatting dates, numbers, currencies, etc. A quick example is you can transfer a string to lowercase by applying a simple filter in the template code.

List of Built-in Pipes from API List ^Examples

{{ user.name | uppercase }}

Example of Angular version 4.4.7. ng version

Custom Pipes which accepts multiple arguments.

HTML « *ngFor="let student of students | jsonFilterBy:[searchText, 'name'] "
TS   « transform(json: any[], args: any[]) : any[] { ... }

Filtering the content using a Pipe « json-filter-by.pipe.ts

    var jsonKey = args[1];

    // json = undefined, args = (2) [undefined, "name"]
    if(searchText == null || searchText == 'undefined') return json;
    if(jsonKey    == null || jsonKey    == 'undefined') return json;

    // Copy all objects of original array into new Array.

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

You can try this it will help for you.You can't get path from WhatsApp directly.If you need an file path first copy file and send new file path. Using the code below

 public static String getFilePathFromURI(Context context, Uri contentUri) {
    String fileName = getFileName(contentUri);
    if (!TextUtils.isEmpty(fileName)) {
        File copyFile = new File(TEMP_DIR_PATH  + fileName+".jpg");
        copy(context, contentUri, copyFile);
        return copyFile.getAbsolutePath();
    }
    return null;
}

public static String getFileName(Uri uri) {
    if (uri == null) return null;
    String fileName = null;
    String path = uri.getPath();
    int cut = path.lastIndexOf('/');
    if (cut != -1) {
        fileName = path.substring(cut + 1);
    }
    return fileName;
}

public static void copy(Context context, Uri srcUri, File dstFile) {
    try {
        InputStream inputStream = context.getContentResolver().openInputStream(srcUri);
        if (inputStream == null) return;
        OutputStream outputStream = new FileOutputStream(dstFile);
        IOUtils.copy(inputStream, outputStream);
        inputStream.close();
        outputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Then IOUtils class is like below

public class IOUtils {



private static final int BUFFER_SIZE = 1024 * 2;

private IOUtils() {
    // Utility class.
}

public static int copy(InputStream input, OutputStream output) throws Exception, IOException {
    byte[] buffer = new byte[BUFFER_SIZE];

    BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);
    BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);
    int count = 0, n = 0;
    try {
        while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {
            out.write(buffer, 0, n);
            count += n;
        }
        out.flush();
    } finally {
        try {
            out.close();
        } catch (IOException e) {
            Log.e(e.getMessage(), e.toString());
        }
        try {
            in.close();
        } catch (IOException e) {
            Log.e(e.getMessage(), e.toString());
        }
    }
    return count;
}


}

Answer is : docker network prune

If you are running on a linux environment, basically your app does not have rights for the default port.

Try 8181 by giving the following option on VM.

-Dserver.port=8181

This worked for me:

using System.ComponentModel.DataAnnotations;

[Key]
public int ID { get; set; }

A simple way to do so is to add the below code (for Seaborn):

for p in splot.patches:
    splot.annotate(format(p.get_height(), '.1f'), 
                   (p.get_x() + p.get_width() / 2., p.get_height()), 
                   ha = 'center', va = 'center', 
                   xytext = (0, 9), 
                   textcoords = 'offset points') 

Example :

splot = sns.barplot(df['X'], df['Y'])
# Annotate the bars in plot
for p in splot.patches:
    splot.annotate(format(p.get_height(), '.1f'), 
                   (p.get_x() + p.get_width() / 2., p.get_height()), 
                   ha = 'center', va = 'center', 
                   xytext = (0, 9), 
                   textcoords = 'offset points')    
plt.show()

For anaconda installation, first pick a channel which has the latest version of tensorflow binary. Usually, the latest versions are available at the channel conda-forge. Then simply do:

conda update -f -c conda-forge tensorflow

This will upgrade your existing tensorflow installation to the very latest version available. As of this writing, the latest version is 1.4.0-py36_0

You should add the code into pom.xml like:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

It looks like they are also using pypi.org now. I added the following to %appdata%\pip\pip.ini and was able to download my packages from behind an HTTPS-intercepting proxy:

trusted-host = pypi.python.org files.pythonhosted.org pypi.org

Usually killall node command fixes mine.

It's a shame that we need multiple ARG too, it results in multiple layers and slows down the build because of that, and for anyone also wondering that, currently there is no way to set multiple ARGs.

In my case i have included jdbc api dependencies in the project so the "Hello World" not printed. After removing the below dependency it works like a charm.

       <dependency>

            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

Open a terminal and take a look at:

/Applications/Python 3.6/Install Certificates.command

Python 3.6 on MacOS uses an embedded version of OpenSSL, which does not use the system certificate store. More details here.

(To be explicit: MacOS users can probably resolve by opening Finder and double clicking Install Certificates.command)

Since TopicService is a Service class, you should annotate it with @Service, so that Spring autowires this bean for you. Like so:

@Service
public class TopicServiceImplementation implements TopicService {
    ...
}

This will solve your problem.

This could be due to the current user having an undefined ExecutionPolicy.

You could try the following:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

I was successful via settings > Terminal > Integrated > Shell: Linux

from there I edited the path of the shell to be /bin/zsh from the default /bin/bash

• there are also options for OSX and Windows as well

@charlieParker - here's what i'm seeing for available commands in the command pallette

In my case, I just added this class and use @EnableAutConfiguration:

@Component
public class SimpleCORSFilter extends GenericFilterBean {
    /**
     * The Logger for this class.
     */
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp,
                         FilterChain chain) throws IOException, ServletException {
        logger.info("> doFilter");

        HttpServletResponse response = (HttpServletResponse) resp;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type");
        //response.setHeader("Access-Control-Allow-Credentials", "true");
        chain.doFilter(req, resp);

        logger.info("< doFilter");
    }
}

reminder that spring doesn't scan the world , it uses targeted scanning wich means everything under the package where springbootapplication is stored. therefore this error "Consider defining a bean of type 'package' in your configuration [Spring-Boot]" may appear because you have services interfaces in a different springbootapplication package .

The expires and add_header directives have no impact on NGINX caching the files, those are purely about what the browser sees.

What you likely want instead is:

location stuffyoudontwanttocache {
    # don't cache it
    proxy_no_cache 1;
    # even if cached, don't try to use it
    proxy_cache_bypass 1; 
}

Though usually .js etc is the thing you would cache, so perhaps you should just disable caching entirely?

Another possible solution - try different Android Studio if you are using some betas. Helped for me. New Android Studio simply didn't add Firebase properly. In my case 3.3preview

After some more investigation I found the problem was that new Android studio starts project with newer Google Services version and it looks it was the original problem. As @Ammar Bukhari suggested this change helped:

classpath 'com.google.gms:google-services:4.1.0' -> classpath 'com.google.gms:google-services:4.0.0'

Update: Guido van Rossum announced on the mailing list that as of Python 3.7 dicts in all Python implementations must preserve insertion order.

If you are using MultiDex in your App Gradle then change extends application to extends MultiDexApplication in your application class. It will defiantly work

It is worth to check if you have refactored package name of your main class annotated with @SpringBootApplication. In that case the testcase should be in an appropriate package otherwise it will be looking for it in the older package . this was the case for me.

You could alter the figsize by passing a tuple showing the width, height parameters you would like to keep.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10,10))         # Sample figsize in inches
sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5, ax=ax)

EDIT

I remember answering a similar question of yours where you had to set the index as TIMESTAMP. So, you could then do something like below:

df = df.set_index('TIMESTAMP')
df.resample('30min').mean()
fig, ax = plt.subplots()
ax = sns.heatmap(df.iloc[:, 1:6:], annot=True, linewidths=.5)
ax.set_yticklabels([i.strftime("%Y-%m-%d %H:%M:%S") for i in df.index], rotation=0)

For the head of the dataframe you posted, the plot would look like:

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

If you want something a little bit more readable, you can try this:

<button @click="[click1($event), click2($event)]">
  Multiple
</button>

To me, this solution feels more Vue-like hope you enjoy

This error just means that myapp.views.home is not something that can be called, like a function. It is a string in fact. While your solution works in django 1.9, nevertheless it throws a warning saying this will deprecate from version 1.10 onwards, which is exactly what has happened. The previous solution by @Alasdair imports the necessary view functions into the script through either from myapp import views as myapp_views or from myapp.views import home, contact

I got the same error message as in the title, but in my case import google was working and import google.protobuf wasn't (on python3.5, ubuntu 16.04).

It turned out that I've installed python3-google-apputils package (using apt) and it was installed to '/usr/lib/python3/dist-packages/google/apputils/', while protobuf (which was installed using pip) was in "/usr/lib/python3.5/dist-packages/google/protobuf/" - and it was a "google" namespace collapse.

Uninstalling google-apputils (from apt, and reinstalling it using pip) solved the problem.

sudo apt remove python3-google-apputils
sudo pip3 install google-apputils

If you provide your JVM the Spring profile there should be no problems:

java -Dspring.profiles.active=development -jar yourApplication.jar 

Also see Spring-Documentation:

http://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html

69.5 Set the active Spring profiles

The Spring Environment has an API for this, but normally you would set a System property (spring.profiles.active) or an OS environment variable (SPRING_PROFILES_ACTIVE). E.g. launch your application with a -D argument (remember to put it before the main class or jar archive):

$ java -jar -Dspring.profiles.active=production demo-0.0.1-SNAPSHOT.jar

In Spring Boot you can also set the active profile in application.properties, e.g.

spring.profiles.active=production

A value set this way is replaced by the System property or environment variable setting, but not by the SpringApplicationBuilder.profiles() method. Thus the latter Java API can be used to augment the profiles without changing the defaults.

See Chapter 25, Profiles in the ‘Spring Boot features’ section for more information.

just for modifying certain property from object collection you could directly use forEach with a collection as follows

collection.forEach(c -> c.setXyz(c.getXyz + "a"))

We were seeing this same issue in one of our old projects that was targeting Framework 4.5.2. I tried several scenarios including all of the ones listed above: target 4.6.1, add System.ValueTuple package, delete bin, obj, and .vs folders. No dice. Repeat the same process for 4.7.2. Then tried removing the System.ValueTuple package since I was targeting 4.7.2 as one commenter suggested. Still nothing. Checked csproj file reference path. Looks right. Even dropped back down to 4.5.2 and installing the package again. All this with several VS restarts and deleting the same folders several times. Literally nothing worked.

I had to refactor to use a struct instead. I hope others don't continue to run into this issue in the future but thought this might be helpful if you end up as stumped up as we were.

at first run the following command :

PM>update-database -migration:0

and then run this one :

PM>remove_migration

Finish

You can now use ts-node, which makes your life as simple as

npm install -D ts-node
npm install -D typescript

ts-node script.ts

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

I try to make it simple. You have two options while using Selenium 3+:

• Either upgrade your Firefox to 47.0.1 or higher and use the default geckodriver of Selenium3.

• Or disable using of geckodriver by specifying marionette to false and use the legacy Firefox driver. a simple command to run selenium is: java -Dwebdriver.firefox.marionette=false -jar selenium-server-standalone-3.0.1.jar. You can also disable using geckodriver from other commands that are mentioned in other answers.

I want to add an answer here that noone has explicitly stated with implementation.

This is a great resource to refer to for this failure: https://matplotlib.org/faq/usage_faq.html

In my case, using matplotlib.use did not work because it was somehow already set somewhere else. However, I was able to get beyond the error by defining an environment variable:

export MPLBACKEND=Agg

This takes care of the issue.

My error was in a CircleCI flow specifically, and this resolved the failing tests. One wierd thing was, my tests would pass when run using pytest, however would fail when using parallelism along with circleci tests split feature. However, declaring this env variable resolved the issue.

port 443 is not open, just allow custom tcp port 443 if on AWS else open the port 443 for the outbound connections ...

I had the same problem in Pre Lollipop devices. To solve that I did as follows. Meantime I was using multiDex in the project.

1. add this for build.gradle in module: app

multiDexEnabled = true

dexOptions {
    javaMaxHeapSize "4g"
}

2. add this dependancy

compile 'com.android.support:multidex:1.0.1'

3.Then in the MainApplication

public class MainApplication extends MultiDexApplication {

private static MainApplication mainApplication;

@Override
public void onCreate() {
    super.onCreate();
    mainApplication = this;
}

@Override
protected void attachBaseContext(Context context) {
    super.attachBaseContext(context);
    MultiDex.install(this);
}


public static synchronized MainApplication getInstance() {
    return mainApplication;
}
}

4.In the manifests file

<application
    android:allowBackup="true"
    android:name="android.support.multidex.MultiDexApplication"

This works for me. Hope this Helps you too :)

For a start simply add the following to your application.properties file

spring.security.user.name=user
spring.security.user.password=pass

NB: with no double quote

Run your application and enter the credentials (user, pass)

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

You must first import the functions:

import org.apache.spark.sql.functions._

Then you can use them like this:

val df = CSV.load(args(0))
val sumSteps =  df.agg(sum("steps")).first.get(0)

You can also cast the result if needed:

val sumSteps: Long = df.agg(sum("steps").cast("long")).first.getLong(0)

Edit:

For multiple columns (e.g. "col1", "col2", ...), you could get all aggregations at once:

val sums = df.agg(sum("col1").as("sum_col1"), sum("col2").as("sum_col2"), ...).first

Edit2:

For dynamically applying the aggregations, the following options are available:

• Applying to all numeric columns at once:

df.groupBy().sum()

• Applying to a list of numeric column names:

val columnNames = List("col1", "col2")
df.groupBy().sum(columnNames: _*)

• Applying to a list of numeric column names with aliases and/or casts:

^{(ansible 2.9.6 ansible-lint 4.2.0)}

See ansible-lint default rules. The condition below causes E602 Don’t compare to empty string

    when: test_myscript.stderr != ""

Correct syntax and also "Ansible Galaxy Warning-Free" option is

    when: test_myscript.stderr | length > 0

Quoting from source code

"Use when: var|length > 0 rather than when: var != "" (or ' 'conversely when: var|length == 0 rather than when: var == "")"

Notes

1. Test empty bare variable e.g.

    - debug:
        msg: "Empty string '{{ var }}' evaluates to False"
      when: not var
      vars:
        var: ''

    - debug:
        msg: "Empty list {{ var }} evaluates to False"
      when: not var
      vars:
        var: []

give

    "msg": "Empty string '' evaluates to False"
    "msg": "Empty list [] evaluates to False"

2. But, testing non-empty bare variable string depends on CONDITIONAL_BARE_VARS. Setting ANSIBLE_CONDITIONAL_BARE_VARS=false the condition works fine but setting ANSIBLE_CONDITIONAL_BARE_VARS=true the condition will fail

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var
      vars:
        var: 'abc'

gives

fatal: [localhost]: FAILED! => 
  msg: |-
    The conditional check 'var' failed. The error was: error while 
    evaluating conditional (var): 'abc' is undefined

Explicit cast to Boolean prevents the error but evaluates to False i.e. will be always skipped (unless var='True'). When the filter bool is used the options ANSIBLE_CONDITIONAL_BARE_VARS=true and ANSIBLE_CONDITIONAL_BARE_VARS=false have no effect

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var|bool
      vars:
        var: 'abc'

gives

skipping: [localhost]

3. Quoting from Porting guide 2.8 Bare variables in conditionals

  - include_tasks: teardown.yml
    when: teardown

  - include_tasks: provision.yml
    when: not teardown

" based on a variable you define as a string (with quotation marks around it):"

• In Ansible 2.7 and earlier, the two conditions above evaluated as True and False respectively if teardown: 'true'

• In Ansible 2.7 and earlier, both conditions evaluated as False if teardown: 'false'

• In Ansible 2.8 and later, you have the option of disabling conditional bare variables, so when: teardown always evaluates as True and when: not teardown always evaluates as False when teardown is a non-empty string (including 'true' or 'false')

4. Quoting from CONDITIONAL_BARE_VARS

"Expect that this setting eventually will be deprecated after 2.12"

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

I think you might want:

String encodedFile = Base64.getEncoder().encodeToString(bytes);

You can run CMD as Administrator and change the permission of the directory using cacls.exe. For example:

cacls.exe c: /t /e /g everyone:F # means everyone can totally control the C: disc

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

Simple using html like this downloads the file mentioned using static keyword

you must stop another running app involved with especial database table ... like running java API in other module or other project is not terminated .. so terminate running.

In my project I have Gradle task for integration test in sub-module:

task intTest(type: Test) {
...
system.properties System.properties 
...

this is the main point to inject all your system params into test environment. So, now you can run gradle like this to pass param with ABC value and use its value by ${param} in your code

gradle :some-service:intTest -Dparam=ABC

Since RestTemplate instances often need to be customized before being used, Spring Boot does not provide any single auto-configured RestTemplate bean.

RestTemplateBuilder offers proper way to configure and instantiate the rest template bean, for example for basic auth or interceptors.

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
    return builder
                .basicAuthorization("user", "name") // Optional Basic auth example
                .interceptors(new MyCustomInterceptor()) // Optional Custom interceptors, etc..
                .build();
}

When it comes to cross-account S3 access

An IAM user policy will not over-ride the policy defined for the bucket in the foreign account.

s3:GetObject must be allowed for accountA/user as well as on the accountB/bucket

Your original problem was wrong pattern symbol "h" which stands for the clock hour (range 1-12). In this case, the am-pm-information is missing. Better, use the pattern symbol "H" instead (hour of day in range 0-23). So the pattern should rather have been like:

uuuu-MM-dd'T'HH:mm:ss.SSSX (best pattern also suitable for strict mode)

I have a lib what use https://requests.readthedocs.io/en/master/ what use https://pypi.org/project/certifi/ but I have a custom CA included in my /etc/ssl/certs.

So I solved my problem like this:

# Your TLS certificates directory (Debian like)
export SSL_CERT_DIR=/etc/ssl/certs
# CA bundle PATH (Debian like again)
export CA_BUNDLE_PATH="${SSL_CERT_DIR}/ca-certificates.crt"
# If you have a virtualenv:
. ./.venv/bin/activate
# Get the current certifi CA bundle
CERTFI_PATH=`python -c 'import certifi; print(certifi.where())'`

test -L $CERTFI_PATH || rm $CERTFI_PATH
test -L $CERTFI_PATH || ln -s $CA_BUNDLE_PATH $CERTFI_PATH

Et voilà !

You are creating an array of zero length (no slots to put anything in)

 int array[]={/*nothing in here = array with no elements*/};

and then trying to assign values to array elements (which you don't have, because there are no slots)

array[i] = number; //array[i] = element i in the array of length 0

You need to define a larger array to fit your needs

 int array[] = new int[4]; //Create an array with 4 elements [0],[1],[2] and [3] each containing an int value

In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.

import javafx.fxml.Initializable;

class MyController implements Initializable {
    @FXML private TableView<MyModel> tableView;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        tableView.getItems().addAll(getDataFromSource());
    }
}

Parameters:

location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized. 

And the note of the docs why the simple way of using @FXML public void initialize() works:

NOTE This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.

It has some interesting behaviour in some cases that is good to be aware of:

from werkzeug.datastructures import MultiDict

d = MultiDict([("ex1", ""), ("ex2", None)])

d.get("ex1", "alternive")
# returns: ''

d.get("ex2", "alternative")
# returns no visible output of any kind
# It is returning literally None, so if you do:
d.get("ex2", "alternative") is None
# it returns: True

d.get("ex3", "alternative")
# returns: 'alternative'

To use arrow functions with function.prototype.call, I made a helper function on the object prototype:

  // Using
  // @func = function() {use this here} or This => {use This here}
  using(func) {
    return func.call(this, this);
  }

usage

  var obj = {f:3, a:2}
  .using(This => This.f + This.a) // 5

Edit

You don't NEED a helper. You could do:

var obj = {f:3, a:2}
(This => This.f + This.a).call(undefined, obj); // 5

Your connection URL should look like the below,

jdbc:mysql://localhost:3306/Peoples?autoReconnect=true&useSSL=false

This will disable SSL and also suppress the SSL errors.

Open xCode can be exhausting if you do it everytime, so you need to add this flag :

• cordova build ios --buildFlag="-UseModernBuildSystem=0"

OR if you have build.json file at the root of your project, you must add this lines:

 {
  "ios": {
    "debug": {
      "buildFlag": [
        "-UseModernBuildSystem=0"
      ]
    },
    "release": {
      "buildFlag": [
        "-UseModernBuildSystem=0"
      ]
    }
  }
}

Hope this will help in the future

Try to add this lines to the top of your settings file:

import django
django.setup()

And if this will not help you try to remove third-party applications from your installed apps list one-by-one.

It is simpler than I thought it would be.

To set the font size of the x-axis ticks:

x_ticks=['x tick 1','x tick 2','x tick 3']
ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)

To do it for the y-axis ticks:

y_ticks=['y tick 1','y tick 2','y tick 3']
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

The arguments rotation and fontsize can easily control what I was after.

command: ["/bin/sh","-c"]
args: ["command one; command two && command three"]

Explanation: The command ["/bin/sh", "-c"] says "run a shell, and execute the following instructions". The args are then passed as commands to the shell. In shell scripting a semicolon separates commands, and && conditionally runs the following command if the first succeed. In the above example, it always runs command one followed by command two, and only runs command three if command two succeeded.

Alternative: In many cases, some of the commands you want to run are probably setting up the final command to run. In this case, building your own Dockerfile is the way to go. Look at the RUN directive in particular.

With links there is an order of container startup being enforced. Without links the containers can start in any order (or really all at once).

I think the old setup could have hit the same issue, if the waapi_php_1 container was slow to startup.

I think to get it working, you could create an nginx entrypoint script that polls and waits for the php container to be started and ready.

I'm not sure if nginx has any way to retry the connection to the upstream automatically, but if it does, that would be a better option.

I got the same error but it was due to me not creating a default constructor. If you haven't already tried that, create the default constructor like this:

public TestClass() {

}

Actually, there's more than one issue here. The main one is that xargs by default executes the command you specified, even when no arguments have been passed. To change that you might use a GNU extension to xargs:

--no-run-if-empty
-r
If the standard input does not contain any nonblanks, do not run the command. Normally, the command is run once even if there is no input. This option is a GNU extension.

Simple example:

find . -mmin -60 | xargs -r ls -l

But this might match to all subdirectories, including . (the current directory), and ls will list each of them individually. So the output will be a mess. Solution: pass -d to ls, which prohibits listing the directory contents:

find . -mmin -60 | xargs -r ls -ld

Now you don't like . (the current directory) in your list? Solution: exclude the first directory level (0) from find output:

find . -mindepth 1 -mmin -60 | xargs -r ls -ld

Now you'd need only the files in your list? Solution: exclude the directories:

find . -type f -mmin -60 | xargs -r ls -l

Now you have some files with names containing white space, quote marks, or backslashes? Solution: use null-terminated output (find) and input (xargs) (these are also GNU extensions, afaik):

find . -type f -mmin -60 -print0 | xargs -r0 ls -l

For completeness, though this probably would not work well given your particular setup (external program + Windows), one can also acquire Scipy hassle-free as part of the (large) SageMath download.

After upgrading Spring boot to the latest version - 2.3.3.RELEASE. I also got this error - Cannot resolve org.springframework.boot:spring-boot-starter-test:unknown. Maven clean install, updating maven project, cleaning cache do not help.
The solution was adding version placeholder from spring boot parent pom:

 <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-test</artifactId>
   <version>${spring-boot.version}</version>
   <scope>test</scope>
 </dependency>

I would just use get_the_post_thumbnail_url() instead of get_the_post_thumbnail()

<img src="<?php echo get_the_post_thumbnail_url($loop->post->ID); ?>" class="img-responsive" alt=""/>

In my case I had created a SB app from the SB Initializer and had included a fair number of deps in it to other things. I went in and commented out the refs to them in the build.gradle file and so was left with:

implementation 'org.springframework.boot:spring-boot-starter-hateoas'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
runtimeOnly 'org.hsqldb:hsqldb'
runtimeOnly 'org.postgresql:postgresql'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.restdocs:spring-restdocs-mockmvc'

as deps. Then my bare-bones SB app was able to build and get running successfully. As I go to try to do things that may need those commented-out libs I will add them back and see what breaks.

If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:

sudo mv geckodriver /usr/local/bin

And it should work.

Has your problem been resolved? What is your target SDK? Try adding android;maxSDKVersion="21" to <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

I have resolved this problem by resizing the image to lower size. I am using xamarin form. decreasing the size of the PNG image resolved the problem.

After seeing

You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I tried again and got

ERROR: To modify pip, please run the following command:
c:\python36-32\python.exe -m pip install -U pip

After running that exact command, it worked.

For those promoting the use of virtual environments as a solution to this error, pip and virtualenv must be updated in your main install. Simply put, a virtual environment offers no solution to this problem.

import boto3, os

s3 = boto3.client('s3')

def download_bucket(bucket):
    paginator = s3.get_paginator('list_objects_v2')
    pages = paginator.paginate(Bucket=bucket)
    for page in pages:
      if 'Contents' in page:
        for obj in page['Contents']:
            os.path.dirname(obj['Key']) and os.makedirs(os.path.dirname(obj['Key']), exist_ok=True) 
            try:
                s3.download_file(bucket, obj['Key'], obj['Key'])
            except NotADirectoryError:
                pass

# Change bucket_name to name of bucket that you want to download
download_bucket(bucket_name)

This should work for all number of objects (also when there are more than 1000). Each paginator page can contain up to 1000 objects.Notice extra param in os.makedirs function - exist_ok=True which cause that it's not throwing error when path exist)

Warnings

I would suggest very strongly against modifying the system Python on Mac; there are numerous issues that can occur.

Your particular error shows that the installer has issues resolving the dependencies for Scrapy without impacting the current Python installation. The system uses Python for a number of essential tasks, so it's important to keep the system installation stable and as originally installed by Apple.

I would also exhaust all other possibilities before bypassing built in security.

Package Manager Solutions:

Please look into a Python virtualization tool such as virtualenv first; this will allow you to experiment safely.

Another useful tool to use languages and software without conflicting with your Mac OS is Homebrew. Like MacPorts or Fink, Homebrew is a package manager for Mac, and is useful for safely trying lots of other languages and tools.

"Roll your own" Software Installs:

If you don't like the package manager approach, you could use the /usr/local path or create an /opt/local directory for installing an alternate Python installation and fix up your paths in your .bashrc. Note that you'll have to enable root for these solutions.

How to do it anyway:

If you absolutely must disable the security check (and I sincerely hope it's for something other than messing with the system languages and resources), you can disable it temporarily and re-enable it using some of the techniques in this post on how to Disable System Integrity-Protection.

If you are trying to run spark without hadoop binaries, you might encounter the above mentioned error. One solution is to :

1) download hadoop separatedly.
2) add hadoop to your PATH
3) add hadoop classpath to your SPARK install

The first two steps are trivial, the last step can be best done by adding the following in the $SPARK_HOME/conf/spark-env.sh in each spark node (master and workers)

### in conf/spark-env.sh ###

export SPARK_DIST_CLASSPATH=$(hadoop classpath)

This problem is caused by RecyclerView Data modified in different thread

Can confirm threading as one problem and since I ran into the issue and RxJava is becoming increasingly popular: make sure that you are using .observeOn(AndroidSchedulers.mainThread()) whenever you're calling notify[whatever changed]

code example from adapter:

myAuxDataStructure.getChangeObservable().observeOn(AndroidSchedulers.mainThread()).subscribe(new Observer<AuxDataStructure>() {

    [...]

    @Override
    public void onNext(AuxDataStructure o) {
        [notify here]
    }
});

I had this issue because the linter was printing that my object was an instance of Foo whereas the compiler couldn't define its type and consider it was an Any object like (It was more complex in my case, the linter show error in below code but the idea is here) :

    class Foo {
        val bar: Int = 0
    }

    fun test(): Any {
        return Foo()
    }

    val foo = test()
    foo.bar // <-- Linter consider that foo is an Instance of Foo but not the compiler because it's an Any object so it show the error at compilation.

To fix it I had to cast my object :

val foo = test() as Foo

UPDATE 24.04.2016.

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)

EDIT

I've tested this on Twenty Fifteen and it's working, so it should be working for you.

In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:

    <div id="ajax-posts" class="row">
        <?php
            $postsPerPage = 3;
            $args = array(
                    'post_type' => 'post',
                    'posts_per_page' => $postsPerPage,
                    'cat' => 8
            );

            $loop = new WP_Query($args);

            while ($loop->have_posts()) : $loop->the_post();
        ?>

         <div class="small-12 large-4 columns">
                <h1><?php the_title(); ?></h1>
                <p><?php the_content(); ?></p>
         </div>

         <?php
                endwhile;
        wp_reset_postdata();
         ?>
    </div>
    <div id="more_posts">Load More</div>

This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with

$cat_id = get_query_var('cat');

This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like

<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>

And pull the category with

var cat = $('#more_posts').data('category');

But for now, you can leave this out.

Next in functions.php I added

wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
    'ajaxurl' => admin_url( 'admin-ajax.php' ),
    'noposts' => __('No older posts found', 'twentyfifteen'),
));

Right after the existing wp_localize_script. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.

At the end of the functions.php file I added the function that will load your posts:

function more_post_ajax(){

    $ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
    $page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;

    header("Content-Type: text/html");

    $args = array(
        'suppress_filters' => true,
        'post_type' => 'post',
        'posts_per_page' => $ppp,
        'cat' => 8,
        'paged'    => $page,
    );

    $loop = new WP_Query($args);

    $out = '';

    if ($loop -> have_posts()) :  while ($loop -> have_posts()) : $loop -> the_post();
        $out .= '<div class="small-12 large-4 columns">
                <h1>'.get_the_title().'</h1>
                <p>'.get_the_content().'</p>
         </div>';

    endwhile;
    endif;
    wp_reset_postdata();
    die($out);
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');

Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.

If you've added your category in the loader, you'd add:

$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';

And instead of 8, you'd put $cat. This will be in the $_POST array, and you'll be able to use it in ajax.

Last part is the ajax itself. In functions.js I put inside the $(document).ready(); enviroment

var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;


function load_posts(){
    pageNumber++;
    var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
    $.ajax({
        type: "POST",
        dataType: "html",
        url: ajax_posts.ajaxurl,
        data: str,
        success: function(data){
            var $data = $(data);
            if($data.length){
                $("#ajax-posts").append($data);
                $("#more_posts").attr("disabled",false);
            } else{
                $("#more_posts").attr("disabled",true);
            }
        },
        error : function(jqXHR, textStatus, errorThrown) {
            $loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
        }

    });
    return false;
}

$("#more_posts").on("click",function(){ // When btn is pressed.
    $("#more_posts").attr("disabled",true); // Disable the button, temp.
    load_posts();
});

Saved it, tested it, and it works :)

Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD

UPDATE

For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;) you can try with

$(window).on('scroll', function () {
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

This should run the load_posts() function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer

$(window).on('scroll', function(){
    if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
        if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
                load_posts();
        }
    }
});

Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100 or $('footer').offset().top for some reason. If that should happen, just increase the number where the scroll goes to.

You can easily check it by putting console.logs in your code and see in the inspector what they throw out

$(window).on('scroll', function () {
    console.log($(window).scrollTop() + $(window).height());
    console.log($(document).height() - 100);
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

And just adjust accordingly ;)

Hope this helps :) If you have any questions just ask.

User doesn't have write permission for some Python installation paths. You can give the permission by:

sudo chown -R $USER /absolute/path/to/directory

So you should give permission, then try to install it again, if you have new paths you should also give permission:

sudo chown -R $USER /usr/local/lib/python2.7/

Another solution in case it helps: in my case, the problem was that I had a @RequestMapping("/xxx") at class level (in my controller), and in the exposed services I had @PostMapping (value = "/yyyy") and @GetMapping (value = "/zzz"); once I commented the @RequestMapping("/xxx") and managed all at method level, worked like a charm.

Well Many people give their answer, some answer is same, some answer id different. I try many answer but they are did not work for me, of course I try from above answer also but did not solve my issue. And I don't know why but I have the same error even my issue solved by this ANSWER. I just want to write it might be helpful for someone.

In my case it was the file size restriction which was put on proxy server. Zip file of gradle was not able to download due this restriction. I was getting 401 error while downloading gradle zip file. If you are getting 401 or 403 error in log, make sure you are able to download those files manually.

but as for this method, I don't understand the purpose of Integer.MAX_VALUE and Integer.MIN_VALUE.

By starting out with smallest set to Integer.MAX_VALUE and largest set to Integer.MIN_VALUE, they don't have to worry later about the special case where smallest and largest don't have a value yet. If the data I'm looking through has a 10 as the first value, then numbers[i]<smallest will be true (because 10 is < Integer.MAX_VALUE) and we'll update smallest to be 10. Similarly, numbers[i]>largest will be true because 10 is > Integer.MIN_VALUE and we'll update largest. And so on.

Of course, when doing this, you must ensure that you have at least one value in the data you're looking at. Otherwise, you end up with apocryphal numbers in smallest and largest.

Note the point Onome Sotu makes in the comments:

...if the first item in the array is larger than the rest, then the largest item will always be Integer.MIN_VALUE because of the else-if statement.

Which is true; here's a simpler example demonstrating the problem (live copy):

public class Example
{
    public static void main(String[] args) throws Exception {
        int[] values = {5, 1, 2};
        int smallest = Integer.MAX_VALUE;
        int largest  = Integer.MIN_VALUE;
        for (int value : values) {
            if (value < smallest) {
                smallest = value;
            } else if (value > largest) {
                largest = value;
            }
        }
        System.out.println(smallest + ", " + largest); // 1, 2 -- WRONG
    }
}

To fix it, either:

1. Don't use else, or

2. Start with smallest and largest equal to the first element, and then loop the remaining elements, keeping the else if.

Here's an example of that second one (live copy):

public class Example
{
    public static void main(String[] args) throws Exception {
        int[] values = {5, 1, 2};
        int smallest = values[0];
        int largest  = values[0];
        for (int n = 1; n < values.length; ++n) {
            int value = values[n];
            if (value < smallest) {
                smallest = value;
            } else if (value > largest) {
                largest = value;
            }
        }
        System.out.println(smallest + ", " + largest); // 1, 5
    }
}

I have encountered the exception java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/7505 in getting the doucument from the downloads. This solution worked for me.

else if (isDownloadsDocument(uri)) {
            String fileName = getFilePath(context, uri);
            if (fileName != null) {
                return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName;
            }

            String id = DocumentsContract.getDocumentId(uri);
            if (id.startsWith("raw:")) {
                id = id.replaceFirst("raw:", "");
                File file = new File(id);
                if (file.exists())
                    return id;
            }

            final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
            return getDataColumn(context, contentUri, null, null);
        }

This the method used to get the filepath

   public static String getFilePath(Context context, Uri uri) {

    Cursor cursor = null;
    final String[] projection = {
            MediaStore.MediaColumns.DISPLAY_NAME
    };

    try {
        cursor = context.getContentResolver().query(uri, projection, null, null,
                null);
        if (cursor != null && cursor.moveToFirst()) {
            final int index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DISPLAY_NAME);
            return cursor.getString(index);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());

Check out this solution. It worked for me..... Check the id of the button for which the error is raised...it may be the same in any one of the other page in your app. If yes, then change the id of them and then the app runs perfectly.

I was having two same button id's in two different XML codes....I changed the id. Now it runs perfectly!! Hope it works

You can check an optionally passed flag with store_true and store_false argument action options:

import argparse

argparser = argparse.ArgumentParser()
argparser.add_argument('-flag', dest='flag_exists', action='store_true')

print argparser.parse_args([])
# Namespace(flag_exists=False)
print argparser.parse_args(['-flag'])
# Namespace(flag_exists=True)

This way, you don't have to worry about checking by conditional is not None. You simply check for True or False. Read more about these options in the docs here

I spent way too much time on this and the solution was super simple. I had to use my "MX" as the host and port 25.

        var sClient = new SmtpClient("domain-com.mail.protection.outlook.com");
        var message = new MailMessage();

        sClient.Port = 25;
        sClient.EnableSsl = true;
        sClient.Credentials = new NetworkCredential("user", "password");
        sClient.UseDefaultCredentials = false;

        message.Body = "Test";
        message.From = new MailAddress("[email protected]");
        message.Subject = "Test";
        message.CC.Add(new MailAddress("[email protected]"));

        sClient.Send(message);

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

To set up VS code path permanently on Mac OS;

just open .bash_profile using the following command on terminal

open -t .bash_profile

Then add the following path to .bash_profile

It could be to do with the package you have it in. I had a similar problem:

Description:

Consider defining a bean of type 'repository.UserRepository' in your configuration. "

Solved it by put the repository files into a package with standardised naming convention:

e.g. com.app.Todo (for main domain files)

and

com.app.Todo.repository (for repository files)

That way, spring knows where to go looking for the repositories, else things get confusing really fast. :)

Hope this helps.

You cannot use the add method on an array in Java.

To add things to the array do it like this

public static void main(String[] args) {
int[] num = new int[args.length];
for (int i = 0; i < args.length; i++){
    int neki = Integer.parseInt(s);
    num[i] = neki;

}

If you really want to use an add() method, then consider using an ArrayList<Integer> instead. This has several advantages - for instance it isn't restricted to a maximum size set upon creation. You can keep adding elements indefinitely. However it isn't quite as fast as an array, so if you really want performance stick with the array. Also it requires you to use Integer object instead of primitive int types, which can cause problems.

ArrayList Example

public static void main(String[] args) {
    ArrayList<Integer> num = new ArrayList<Integer>();
    for (String s : args){
        Integer neki = new Integer(Integer.parseInt(s));
        num.add(s);
}

At least you can change your loop from a busy-wait to a slow poll. For example:

    while (!isExcelInteractive())
    {
        Console.WriteLine("Excel is busy");
        await Task.Delay(25);
    }

Here is another answer using Spring MVC's standaloneSetup. Using this way you can either autowire the controller class or Mock it.

    import static org.mockito.Mockito.mock;
    import static org.springframework.test.web.server.request.MockMvcRequestBuilders.get;
    import static org.springframework.test.web.server.result.MockMvcResultMatchers.content;
    import static org.springframework.test.web.server.result.MockMvcResultMatchers.status;

    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.http.MediaType;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    import org.springframework.test.web.server.MockMvc;
    import org.springframework.test.web.server.setup.MockMvcBuilders;


    @RunWith(SpringJUnit4ClassRunner.class)
    @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
    public class DemoApplicationTests {

        final String BASE_URL = "http://localhost:8080/";

        @Autowired
        private HelloWorld controllerToTest;

        private MockMvc mockMvc;

        @Before
        public void setup() {
            this.mockMvc = MockMvcBuilders.standaloneSetup(controllerToTest).build();
        }

        @Test
        public void testSayHelloWorld() throws Exception{
            //Mocking Controller
            controllerToTest = mock(HelloWorld.class);

             this.mockMvc.perform(get("/")
                     .accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
                     .andExpect(status().isOk())
                     .andExpect(content().mimeType(MediaType.APPLICATION_JSON));
        }

        @Test
        public void contextLoads() {
        }

    }

Try adding the RunAs option to your Start-Process

Start-Process powershell.exe -Credential $Credential -Verb RunAs -ArgumentList ("-file $args")

This question has been asked long ago but none of the answers above helped me out, though Milad Moosavi`s answer was very close. To open a new activity from a certain position on the recycler view, the following code may help:

    @Override
    public void onBindViewHolder(@NonNull TripViewHolder holder, int position) {
        Trip currentTrip = trips.get(position);

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(v.getContext(), EditTrip.class);
                v.getContext().startActivity(intent);
            }
        });

        holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Intent intent = new Intent(v.getContext(), ReadTripActivity.class);
                v.getContext().startActivity(intent);

                return false;
            }
        });
    }

I had this same problem but only when running spring boot tests cases that required JPA. The end result was that our own jpa test configuration was initializing an EntityManagerFactory and setting the packages to scan. This evidently will override the EntityScan parameters if you are setting it manually.

    final LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter( vendorAdapter );
    factory.setPackagesToScan( Project.class.getPackage().getName());
    factory.setDataSource( dataSource );

Important to note: if you are still stuck you should set a break point in the org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager on the setPackagesToScan() method and take a look at where this is being called and what packages are being passed to it.

I am also facing same issue in Hortonworks

At the time I restart the Ambari agents and servers then the issue has been resolved.

 systemctl stop ambari-agent

You're the victim of the classic deadlock. task.Wait() or task.Result is a blocking call in UI thread which causes the deadlock.

Don't block in the UI thread. Never do it. Just await it.

private async void Button_Click(object sender, RoutedEventArgs 
{
      var task = GetResponseAsync<MyObject>("my url");
      var items = await task;
}

Btw, why are you catching the WebException and throwing it back? It would be better if you simply don't catch it. Both are same.

Also I can see you're mixing the asynchronous code with synchronous code inside the GetResponse method. StreamReader.ReadToEnd is a blocking call --you should be using StreamReader.ReadToEndAsync.

Also use "Async" suffix to methods which returns a Task or asynchronous to follow the TAP("Task based Asynchronous Pattern") convention as Jon says.

Your method should look something like the following when you've addressed all the above concerns.

public static async Task<List<T>> GetResponseAsync<T>(string url)
{
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
    var response = (HttpWebResponse)await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null);

    Stream stream = response.GetResponseStream();
    StreamReader strReader = new StreamReader(stream);
    string text = await strReader.ReadToEndAsync();

    return JsonConvert.DeserializeObject<List<T>>(text);
}

In your public View getView method change return null; to return convertView;.

There's more than one way to skin this problem so here's my solution:

1. Use Select() to convert the key-value pair to a string;
2. Convert to a list of strings;
3. Write out to the console using ForEach().

dict.Select(i => $"{i.Key}: {i.Value}").ToList().ForEach(Console.WriteLine);

Value cannot be null. Parameter name: source

Above error comes in situation when you are querying the collection which is null.

For demonstration below code will result in such an exception.

Console.WriteLine("Hello World");
IEnumerable<int> list = null;
list.Where(d => d ==4).FirstOrDefault();

Here is the output of the above code.

Hello World Run-time exception (line 11): Value cannot be null. Parameter name: source

Stack Trace:

[System.ArgumentNullException: Value cannot be null. Parameter name: source] at Program.Main(): line 11

In your case ListMetadataKor is null. Here is the fiddle if you want to play around.

I have found the mistake what I did. We need to get the activity instance from the override method OnAttach() For example,

public MainActivity activity;

@Override
public void onAttach(Activity activity){
    this.activity = activity;
}

Then pass the activity as context as following.

Intent mIntent = new Intent(activity, MusicHome.class);

namespace TestCSharp2
{
    **public** class Class2
    {
        int i;
        public void setValue(int i)
        {
            this.i = i;
        }
        public int getValue()
        {
        return this.i;
        }
    }
}

Add the 'Public' declaration before 'class Class2'.

An utility method like the following can be used to solve this.

import (
  "os"
  "path/filepath"
  "log"
)

func ensureDir(fileName string) {
  dirName := filepath.Dir(fileName)
  if _, serr := os.Stat(dirName); serr != nil {
    merr := os.MkdirAll(dirName, os.ModePerm)
    if merr != nil {
        panic(merr)
    }
  }
}



func main() {
  _, cerr := os.Create("a/b/c/d.txt")
  if cerr != nil {
    log.Fatal("error creating a/b/c", cerr)
  }
  log.Println("created file in a sub-directory.")
}

I needed to make report for a catering firm which serves lunches for various clients. In other words, catering may have on or more firms which take orders from catering, and it must know how many lunches it must produce every single day for all it's clients !

Just to notice, I didn't use sorting, in order not to over complicate this example.

This is my code :

@Test
public void test_2() throws Exception {
    Firm catering = DS.firm().get(1);
    LocalDateTime ldtFrom = LocalDateTime.of(2017, Month.JANUARY, 1, 0, 0);
    LocalDateTime ldtTo = LocalDateTime.of(2017, Month.MAY, 2, 0, 0);
    Date dFrom = Date.from(ldtFrom.atZone(ZoneId.systemDefault()).toInstant());
    Date dTo = Date.from(ldtTo.atZone(ZoneId.systemDefault()).toInstant());

    List<PersonOrders> LON = DS.firm().getAllOrders(catering, dFrom, dTo, false);
    Map<Object, Long> M = LON.stream().collect(
            Collectors.groupingBy(p
                    -> Arrays.asList(p.getDatum(), p.getPerson().getIdfirm(), p.getIdProduct()),
                    Collectors.counting()));

    for (Map.Entry<Object, Long> e : M.entrySet()) {
        Object key = e.getKey();
        Long value = e.getValue();
        System.err.println(String.format("Client firm :%s, total: %d", key, value));
    }
}

For anyone else who has a BaseActivity, and a child that extends from it, make sure the super.onCreate() is called first before you do anything. The old Activity would work if you called super.onCreate() afterwards.

Child extends Activity - could call super after you did stuff

@Override
protected void onCreate(Bundle savedInstanceState)
{
    getActionBar().setDisplayHomeAsUpEnabled(true);
    super.onCreate(savedInstanceState);

Child extends AppCompatActivity - ya gotta call super first

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState); //do this first
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

Looks like the initial problem is with the auto-config.

If you don't need the datasource, simply remove it from the auto-config process:

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

The message that you are getting is not for the default Exception of Python:

For a fresh python list, IndexError is thrown only on index not being in range (even docs say so).

>>> l = []
>>> l[1]
IndexError: list index out of range

If we try passing multiple items to list, or some other value, we get the TypeError:

>>> l[1, 2]
TypeError: list indices must be integers, not tuple

>>> l[float('NaN')]
TypeError: list indices must be integers, not float

However, here, you seem to be using matplotlib that internally uses numpy for handling arrays. On digging deeper through the codebase for numpy, we see:

static NPY_INLINE npy_intp
unpack_tuple(PyTupleObject *index, PyObject **result, npy_intp result_n)
{
    npy_intp n, i;
    n = PyTuple_GET_SIZE(index);
    if (n > result_n) {
        PyErr_SetString(PyExc_IndexError,
                        "too many indices for array");
        return -1;
    }
    for (i = 0; i < n; i++) {
        result[i] = PyTuple_GET_ITEM(index, i);
        Py_INCREF(result[i]);
    }
    return n;
}

where, the unpack method will throw an error if it the size of the index is greater than that of the results.

So, Unlike Python which raises a TypeError on incorrect Indexes, Numpy raises the IndexError because it supports multidimensional arrays.

You can move Application.java to a folder under the java.

Per this github comment, one can disable urllib3 request warnings via requests in a 1-liner:

requests.packages.urllib3.disable_warnings()

This will suppress all warnings though, not just InsecureRequest (ie it will also suppress InsecurePlatform etc). In cases where we just want stuff to work, I find the conciseness handy.

If you have multiple sub-projects then you need to add the resources folder to each project's run configuration class path like so:

Ensure the new path is top of the entries and then the runtime will check that path first for any resources (before checking sub-paths)

The word check_ in the name means that if the command (the shell in this case that returns the exit status of the last command (yum in this case)) returns non-zero status then it raises CalledProcessError exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_ methods. You could use subprocess.call in your case because you are ignoring the captured output, e.g.:

import subprocess

rc = subprocess.call(['grep', 'pattern', 'file'],
                     stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
   ...
elif rc == 1: # not found
   ...
elif rc > 1: # error
   ...

You don't need shell=True to run the commands from your question.

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

After following the guide (or using Spring Initializr), I had a WAR that worked on my local computer, but didn't work remote (running on Tomcat).

There was no error message, it just said "Spring servlet initializer was found", but didn't do anything at all.

17-Aug-2016 16:58:13.552 INFO [main] org.apache.catalina.core.StandardEngine.startInternal Starting Servlet Engine: Apache Tomcat/8.5.4

Nothing else happened. Spring Boot just didn't run.

Apparently I compiled the server with Java 1.8, and the remote computer had Java 1.7.

After compiling with Java 1.7, it started working.

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.7</java.version> <!-- added this line -->
    <start-class>myapp.SpringApplication</start-class>
</properties>

called_from must be null. Add a test against that condition like

if (called_from != null && called_from.equalsIgnoreCase("add")) {

or you could use Yoda conditions (per the Advantages in the linked Wikipedia article it can also solve some types of unsafe null behavior they can be described as placing the constant portion of the expression on the left side of the conditional statement)

if ("add".equalsIgnoreCase(called_from)) { // <-- safe if called_from is null

Solution for Anaconda

My setup is Anaconda Python 3.7 on MacOS with a proxy. The paths are different.

• This is how you get the correct certificates path:

import ssl
ssl.get_default_verify_paths()

which on my system produced

Out[35]: DefaultVerifyPaths(cafile='/miniconda3/ssl/cert.pem', capath=None,
 openssl_cafile_env='SSL_CERT_FILE', openssl_cafile='/miniconda3/ssl/cert.pem',
 openssl_capath_env='SSL_CERT_DIR', openssl_capath='/miniconda3/ssl/certs')

Once you know where the certificate goes, then you concatenate the certificate used by the proxy to the end of that file.

I had already set up conda to work with my proxy, by running:

conda config --set ssl_verify <pathToYourFile>.crt

If you don't remember where your cert is, you can find it in ~/.condarc:

ssl_verify: <pathToYourFile>.crt

Now concatenate that file to the end of /miniconda3/ssl/cert.pem and requests should work, and in particular sklearn.datasets and similar tools should work.

Further Caveats

The other solutions did not work because the Anaconda setup is slightly different:

• The path Applications/Python\ 3.X simply doesn't exist.

• The path provided by the commands below is the WRONG path

from requests.utils import DEFAULT_CA_BUNDLE_PATH
DEFAULT_CA_BUNDLE_PATH

I went ahead and downloaded the project from the link you provided: http://javapapers.com/android/android-chat-bubble/

Since this is an old tutorial, you simply need to upgrade the software, gradle, the android build tools and plugin.

Make sure you have the latest Gradle and Android Studio:

• https://www.gradle.org/
• http://tools.android.com/tech-docs/new-build-system/version-compatibility

build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

app/build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName '1.0'
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.2.1'
}

Then run gradle:

gradle installDebug

When everything sounded so complicated, this command worked for me:

keytool -genkey -alias foo -keystore cacerts -dname cn=test -storepass changeit -keypass changeit

When a developer is in trouble, I believe a simple working solution snippet is more than enough for him. Later he could diagnose the root cause and basic understanding related to the issue.

Update 2018-01-07 with Spring Boot 1.5.8.RELEASE

If you want to know how to config it, how to use it, and how to control transaction. I may have answers for you.

You can see the runnable example and some explanation in https://www.surasint.com/spring-boot-with-multiple-databases-example/

I copied some code here.

First you have to set application.properties like this

#Database
database1.datasource.url=jdbc:mysql://localhost/testdb
database1.datasource.username=root
database1.datasource.password=root
database1.datasource.driver-class-name=com.mysql.jdbc.Driver

database2.datasource.url=jdbc:mysql://localhost/testdb2
database2.datasource.username=root
database2.datasource.password=root
database2.datasource.driver-class-name=com.mysql.jdbc.Driver

Then define them as providers (@Bean) like this:

@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
    return DataSourceBuilder.create().build();
}

@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
    return DataSourceBuilder.create().build();
}

Note that I have @Bean(name="datasource1") and @Bean(name="datasource2"), then you can use it when we need datasource as @Qualifier("datasource1") and @Qualifier("datasource2") , for example

@Qualifier("datasource1")
@Autowired
private DataSource dataSource;

If you do care about transaction, you have to define DataSourceTransactionManager for both of them, like this:

@Bean(name="tm1")
@Autowired
@Primary
DataSourceTransactionManager tm1(@Qualifier ("datasource1") DataSource datasource) {
    DataSourceTransactionManager txm  = new DataSourceTransactionManager(datasource);
    return txm;
}

@Bean(name="tm2")
@Autowired
DataSourceTransactionManager tm2(@Qualifier ("datasource2") DataSource datasource) {
    DataSourceTransactionManager txm  = new DataSourceTransactionManager(datasource);
    return txm;
}

Then you can use it like

@Transactional //this will use the first datasource because it is @primary

or

@Transactional("tm2")

This should be enough. See example and detail in the link above.

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

In Gradle implement this library :

implementation 'com.android.support:appcompat-v7:SDK_VER'
implementation 'com.android.support:design:SDK_VER'
implementation 'com.android.support:support-v4:SDK_VER'
implementation 'com.android.support:support-v13:SDK_VER'
implementation 'com.android.support:recyclerview-v7:SDK_VER'

In XML mention like this :

<android.support.v7.widget.RecyclerView
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:id="@+id/recyclerView"/>

In Fragment we use recyclerView like this :

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
       View rootView = inflater.inflate(R.layout.YOUR_LAYOUT_NAME, container, false);

       RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
        RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
        recyclerView.setLayoutManager(layoutManager);
        APICallMethod();
        YOURADAPTER = new YOURADAPTER(getActivity(), YOUR_LIST); // you can use that adapter after for loop in response(APICALLMETHOD)
        recyclerView.setAdapter(YOURADAPTER);
        return rootView;
    }

In Activity we use RecyclerView like this :

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.YOUR_LAYOUT_NAME);

        RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
        RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
        recyclerView.setLayoutManager(layoutManager);
        APICallMethod();
        YOURADAPTER = new YOURADAPTER(ACTIVITY_NAME.this, YOUR_LIST); // you can use that adapter after for loop in response(APICALLMETHOD)
        recyclerView.setAdapter(YOURADAPTER);
   }

if you need horizontal RecyclerView do this :

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
        RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
        recyclerView.setLayoutManager(layoutManager);
        APICallMethod();
        YOURADAPTER = new YOURADAPTER(ACTIVITY_NAME.this, YOUR_LIST); // you can use that adapter after for loop in response(APICALLMETHOD)
        recyclerView.setAdapter(YOURADAPTER);

if you want to use GridLayoutManager using RecyclerView use like this :

        RecyclerView recyclerView = findViewById(R.id.rvNumbers);
        recyclerView.setLayoutManager(new GridLayoutManager(this, 3)); // 3 is number of columns.
        adapter = new MyRecyclerViewAdapter(this, data);
        recyclerView.setAdapter(adapter);

This issue is due to ArrayList variable not being instantiated. Need to declare "recordings" variable like following, that should solve the issue;

ArrayList<String> recordings = new ArrayList<String>();

this calls default constructor and assigns empty string to the recordings variable so that it is not null anymore.

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

This error occurs because your Eclipse version is 64-bit. You should download and install 64-bit JRE and add the path to it in eclipse.ini. For example:

...
--launcher.appendVmargs
-vm
C:\Program Files\Java\jre1.8.0_45\bin\javaw.exe
-vmargs
...

Note: The -vm parameter should be just before -vmargs and the path should be on a separate line. It should be the full path to the javaw.exe file. Do not enclose the path in double quotes (").

If your Eclipse is 32-bit, install a 32-bit JRE and use the path to its javaw.exe file.

Might as well make this an answer. I had the same issue today and it was more of a non-issue than expected. After adding the CORS functionality, you must restart your Flask server (ctrl + c -> python manage.py runserver, or whichever method you use)) in order for the change to take effect, even if the code is correct. Otherwise the CORS will not work in the active instance.

Here's how it looks like for me and it works (Python 3.6.1, Flask 0.12):

factory.py:

from flask import Flask
from flask_cors import CORS  # This is the magic


def create_app(register_stuffs=True):
    """Configure the app and views"""
    app = Flask(__name__)
    CORS(app)  # This makes the CORS feature cover all routes in the app

    if register_stuffs:
        register_views(app)
    return app


def register_views(app):
    """Setup the base routes for various features."""
    from backend.apps.api.views import ApiView
    ApiView.register(app, route_base="/api/v1.0/")

views.py:

from flask import jsonify
from flask_classy import FlaskView, route


class ApiView(FlaskView):
    @route("/", methods=["GET"])
    def index(self):
        return "API v1.0"

    @route("/stuff", methods=["GET", "POST"])
    def news(self):
        return jsonify({
            "stuff": "Here be stuff"
        })

In my React app console.log:

Sending request:
GET /stuff
With parameters:
null
bundle.js:17316 Received data from Api:
{"stuff": "Here be stuff"}

Here is the code with line 156, it has try and catch above it

    /// <summary>
    /// Execute a SQL Query statement, using the default SQL connection for the application
    /// </summary>
    /// <param name="query">SQL query to execute</param>

    public static DataTable Query(string query)
    {
        DataTable results = new DataTable();
        string configConnectionString = "ApplicationServices";

        System.Configuration.Configuration WebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~/Web.config");
        System.Configuration.ConnectionStringSettings connString;

        if (WebConfig.ConnectionStrings.ConnectionStrings.Count > 0)
        {
            connString = WebConfig.ConnectionStrings.ConnectionStrings[configConnectionString];

            if (connString != null)
            {

                        dataAdapter.Fill(results);

                    return results;
                }
                catch (Exception ex)
                {
                    throw new SqlException(string.Format("SqlException occurred during query execution: ", ex));
                }

        }
        else

        }
    }

You need to provide configurations considering your Spring Boot Version and the version of libraries it downloads based on the same.

My Setup: Spring Boot 1.5.x (1.5.10 in my case) downloads Hibernate v5.x

Use below only if your Spring Boot setup has downloaded Hibernate v4.

spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy

Hibernate 5 doesn't support above.

If your Spring Boot Setup has downloaded Hibernate v5.x, then prefer below definition:

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

IMPORTANT: In your Spring Boot application development, you should prefer to use annotation: @SpringBootApplication which has been super-annotated with: @SpringBootConfiguration and @EnableAutoConfiguration

NOW If your entity classes are in different package than the package in which your Main Class resides, Spring Boot won't scan those packages.

Thus you need to explicitly define Annotation: @EntityScan(basePackages = { "com.springboot.entities" })
This annotation scans JPA based annotated entity classes (and others like MongoDB, Cassandra etc)

NOTE: "com.springboot.entities" is the custom package name.

Following is the way I had defined Hibernate and JPA based properties at application.properties to create Tables:-

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3333/development?useSSL=true spring.datasource.username=admin
spring.datasource.password=

spring.jpa.open-in-view=false
spring.jpa.hibernate.ddl-auto=create
spring.jpa.generate-ddl=true
spring.jpa.hibernate.use-new-id-generator-mappings=true
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.naming.strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.format_sql=true

I am able to create tables using my above mentioned configuration.

Refer it and change your code wherever applicable.

1. Download SciPy from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
2. Go into the directory the downloaded file is in and pip install the file.
3. Go to python shell, run import scipy; it worked for me with no errors.

In my case, a problem was in calling inflater.inflate(R.layout.some_layout, null). Null as ViewGroup parameter was the problem.

Just put parent="Theme.AppCompat.NoActionBar" in your style.xml file

Like - <style parent="Theme.AppCompat.NoActionBar" name="AppTheme.NoActionBar">

Step1:

Go to cordova\platforms\android ant create a fille called ant.properties file with the keystore file info (this keystore can be generated from your favorite Android SDK, studio...):

key.store=C:\\yourpath\\Yourkeystore.keystore
key.alias=youralias

Step2:

Go to cordova path and execute:

cordova build android --release

Note: You will be prompted asking your keystore and key password

An YourApp-release.apk will appear in \cordova\platforms\android\ant-build

You can use the library SectionedRecyclerViewAdapter to group your items in sections and add a header to each section, like on the image below:

First you create your section class:

class MySection extends StatelessSection {

    String title;
    List<String> list;

    public MySection(String title, List<String> list) {
        // call constructor with layout resources for this Section header, footer and items 
        super(R.layout.section_header, R.layout.section_item);

        this.title = title;
        this.list = list;
    }

    @Override
    public int getContentItemsTotal() {
        return list.size(); // number of items of this section
    }

    @Override
    public RecyclerView.ViewHolder getItemViewHolder(View view) {
        // return a custom instance of ViewHolder for the items of this section
        return new MyItemViewHolder(view);
    }

    @Override
    public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
        MyItemViewHolder itemHolder = (MyItemViewHolder) holder;

        // bind your view here
        itemHolder.tvItem.setText(list.get(position));
    }

    @Override
    public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
        return new SimpleHeaderViewHolder(view);
    }

    @Override
    public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
        MyHeaderViewHolder headerHolder = (MyHeaderViewHolder) holder;

        // bind your header view here
        headerHolder.tvItem.setText(title);
    }
}

Then you set up the RecyclerView with your sections and change the SpanSize of the headers with a GridLayoutManager:

// Create an instance of SectionedRecyclerViewAdapter 
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();

// Create your sections with the list of data
MySection section1 = new MySection("My Section 1 title", dataList1);
MySection section2 = new MySection("My Section 2 title", dataList2);

// Add your Sections to the adapter
sectionAdapter.addSection(section1);
sectionAdapter.addSection(section2);

// Set up a GridLayoutManager to change the SpanSize of the header
GridLayoutManager glm = new GridLayoutManager(getContext(), 2);
glm.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        switch(sectionAdapter.getSectionItemViewType(position)) {
            case SectionedRecyclerViewAdapter.VIEW_TYPE_HEADER:
                return 2;
            default:
                return 1;
        }
    }
});

// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(glm);
recyclerView.setAdapter(sectionAdapter);

goto doesn't do anything in Java.

Step 1: Delete the db.sqlite3 file.

Step 2 : $ python manage.py migrate

Step 3 : $ python manage.py makemigrations

Step 4: Create the super user using $ python manage.py createsuperuser

new db.sqlite3 will generates automatically

don't know why, but it works. Two configuration are the same, just change xxx to your name.

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "xxxEntityManager",
    transactionManagerRef = "xxxTransactionManager",
    basePackages = {"aaa.xxx"})
 public class RepositoryConfig {
@Autowired
private Environment env;

@Bean
@Primary
@ConfigurationProperties(prefix="datasource.xxx")
public DataSource xxxDataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
public LocalContainerEntityManagerFactoryBean xxxEntityManager() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(xxxDataSource());
    em.setPackagesToScan(new String[] {"aaa.xxx"});

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<String, Object> properties = new HashMap<String, Object>();
    properties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
    properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
    properties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
    em.setJpaPropertyMap(properties);

    return em;
}

@Bean(name = "xxxTransactionManager")
public PlatformTransactionManager xxxTransactionManager() {
    JpaTransactionManager tm = new JpaTransactionManager();
    tm.setEntityManagerFactory(xxxEntityManager().getObject());
    return tm;
}

}

For calling the method of one class within the second class, you have to first create the object of that class which method you want to call than with the object reference you can call the method.

class A {
   public void fun(){
     //do something
   }
}

class B {
   public static void main(String args[]){
     A obj = new A();
     obj.fun();
   }
}

But in your case you have the static method in Date and TemperatureRange class. You can call your static method by using the class name directly like below code or by creating the object of that class like above code but static method ,mostly we use for creating the utility classes, so best way to call the method by using class name. Like in your case -

public static void main (String[] args){
  String dateVal = Date.date("01","11,"12"); // calling the date function by passing some parameter.

  String tempRangeVal = TemperatureRange.TempRange("80","20"); 
}

In your xyz.DAOImpl.java

Do the following steps:

//Step-1: Set session factory

@Resource(name="sessionFactory")
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sf)
{
    this.sessionFactory = sf;
}

//Step-2: Try to get the current session, and catch the HibernateException exception.

---

//Step-3: If there are any HibernateException exception, then true to get openSession.

try 
{
    //Step-2: Implementation
    session = sessionFactory.getCurrentSession();
} 
catch (HibernateException e) 
{
    //Step-3: Implementation
    session = sessionFactory.openSession();
}

I have checked all possible solutions including re-installation of JDK, eclipse as it worked for many people but unfortunately it didn't work for me. Also updated main class in pom.xml but it didn't help. It took my sleep away. I was trying different options and suddenly the magic happened when I checked this checkbox. It might be helpful for many people so thought of sharing

Short answer

If running into this at home on a corporate machine, try again at work.

Details

I ran into this over the weekend. Pip and conda both broken, unable to install or update. SO was helpful, but many answers were problematic on a corporate machine - the solutions require the ability to pip install (already does not work) or require downloading an installer (the ones I wanted to download were prohibited by firewall settings).

What worked for me was to try again when I was on prem. This worked. It turned out the corporate firewall settings were different when using the machine at home vs at work.

Faced similar issue, and here is the solution

Example :

1. In elasticsearch.yml add the below properties

   cluster.name: production
   node.name: node1
   network.bind_host: 10.0.1.22
   network.host: 0.0.0.0
   transport.tcp.port: 9300
   

2. Add the following in Java Elastic API for Bulk Push (just a code snippet). For IP Address add public IP address of elastic search machine

   Client client;
   BulkRequestBuilder requestBuilder;
   try {
       client = TransportClient.builder().settings(Settings.builder().put("cluster.name", "production").put("node.name","node1")).build().addTransportAddress(
       new InetSocketTransportAddress(InetAddress.getByName(""), 9300));
       requestBuilder = (client).prepareBulk();
   } 
   catch (Exception e) {
   }
   

3. Open the Firewall ports for 9200,9300

not Error:

JSONObject json1 = getJsonX();

Error:

JSONObject json2 = null;
if(x == y)
   json2 = getJSONX();

Error: Local variable statement defined in an enclosing scope must be final or effectively final.

But you can write:

JSONObject json2 = (x == y) ? json2 = getJSONX() : null;

I encountered this limitation too and created this library to overcome the issue: spring-boot-jar-resources It basically allows you to register a custom ResourceLoader with Spring Boot that extracts the classpath resources from the JAR as needed, transparently.

On a Mac, you need to use this command:

STATIC_DEPS=true sudo pip install lxml

The user "geoand" is right in pointing out the reasons here and giving a solution. But a better approach is to encapsulate your configuration into a separate class, say SystemContiguration java class and then inject this class into what ever services you want to use those fields.

Your current way(@grahamrb) of reading config values directly into services is error prone and would cause refactoring headaches if config setting name is changed.

After more than five years I answer my question. I think that the problem with a negative duration can be solved by a simple correction:

LocalDateTime fromDateTime = LocalDateTime.of(2014, 9, 9, 7, 46, 45);
LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 46, 45);

Period period = Period.between(fromDateTime.toLocalDate(), toDateTime.toLocalDate());
Duration duration = Duration.between(fromDateTime.toLocalTime(), toDateTime.toLocalTime());

if (duration.isNegative()) {
    period = period.minusDays(1);
    duration = duration.plusDays(1);
}
long seconds = duration.getSeconds();
long hours = seconds / SECONDS_PER_HOUR;
long minutes = ((seconds % SECONDS_PER_HOUR) / SECONDS_PER_MINUTE);
long secs = (seconds % SECONDS_PER_MINUTE);
long time[] = {hours, minutes, secs};
System.out.println(period.getYears() + " years "
            + period.getMonths() + " months "
            + period.getDays() + " days "
            + time[0] + " hours "
            + time[1] + " minutes "
            + time[2] + " seconds.");

Note: The site https://www.epochconverter.com/date-difference now correctly calculates the time difference.

Thank you all for your discussion and suggestions.

I see only two options:

1. You have memory leaks in your application.
2. Devices do not have enough memory when running your application.

I solved this by Following steps:

1. Uninstalled python
2. removed Python37 Folder from C/program files/ and user/sukhendra/AppData
3. removed all python37 paths

then only Anaconda is remaining in my PC so opened Anaconda and then it's all working fine for me

There is no way how to declare an unsigned long or int in Java 8 or Java 9. But some methods treat them as if they were unsigned, for example:

static long values = Long.parseUnsignedLong("123456789012345678");

but this is not declaration of the variable.

Is this a simple eclipse java project without maven etc? In that case you will need to put the log4j2.xml file under src folder in order to be able to find it on the classpath. If you use maven put it under src/main/resources or src/test/resources

To begin with (and unrelated), instantiating the Application class by yourself does not seem to be its intended use. From what one can read from its source, you are rather expected to use the static instance returned by getApplication().

Now let's get to the error Eclipse reports. I've ran into a similar issue recently: Access restriction: The method ... is not API (restriction on required project). I called the method in question as a method of an object which inherited that method from a super class. All I had to do was to add the package the super class was in to the packages imported by my plugin.

However, there is a lot of different causes for errors based on "restriction on required project/library". Similar to the problem described above, the type you are using might have dependencies to packages that are not exported by the library or might not be exported itself. In that case you can try to track down the missing packages and export them my yourself, as suggested here, or try Access Rules. Other possible scenarios include:

• Eclipse wants to keep you from using available packages that are not part of the public Java API (solution 1, 2)
• Dependencies are satisfied by multiple sources, versions are conflicting etc. (solution 1, 2, 3)
• Eclipse is using a JRE where a JDK is necessary (which might be the case here, from what your errors say; solution) or JRE/JDK version in project build path is not the right one

This ended up as more like a medley of restriction-related issues than an actual answer. But since restriction on required projects is such a versatile error to be reported, the perfect recipe is probably still to be found.

After hours of analysis reading tons of logs and sourcecode, finally found problem. And it is quite easy to solve it.

in sinle line: you need to pass --whitelisted-ips= into chrome driver (not chrome!) executables

You can do it in few ways:

If you use ChromeDriver locally/directly from code, just insert lines below before ChromeDriver init

    System.setProperty("webdriver.chrome.whitelistedIps", "");

If you use it remotely (eg. selenium hub/grid) you need to set system property when node starts, like in command:

java -Dwebdriver.chrome.whitelistedIps= testClass etc...

or docker by passing JAVA_OPTS env

  chrome:
    image: selenium/node-chrome:3.141.59
    container_name: chrome
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
      - JAVA_OPTS=-Dwebdriver.chrome.whitelistedIps=

After all i got the answer thanks to wikisona, first the beans:

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }

        @Override
        protected void postProcessContext(Context context) {
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/myDataSource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", "your.db.Driver");
            resource.setProperty("url", "jdbc:yourDb");

            context.getNamingResources().addResource(resource);
        }
    };
}

@Bean(destroyMethod="")

    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("java:comp/env/jdbc/myDataSource");
    bean.setProxyInterface(DataSource.class);
    bean.setLookupOnStartup(false);
    bean.afterPropertiesSet();
    return (DataSource)bean.getObject();
}

the full code it's here: https://github.com/wilkinsona/spring-boot-sample-tomcat-jndi

For those of you who still don't understand after reading @meda answer, here is my concise and complete explanation for this issue:

Let's say you have 2 Fragments, Fragment_A and Fragment_B which are auto-generated from the app. On the bottom part of your generated fragments, you're going to find this code:

public class Fragment_A extends Fragment {

    //rest of the code is omitted

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        public void onFragmentInteraction(Uri uri);
    }
}

public class Fragment_B extends Fragment {

    //rest of the code is omitted

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        public void onFragmentInteraction(Uri uri);
    }
}

To overcome the issue, you have to add onFragmentInteraction method into your activity, which in my case is named MainActivity2. After that, you need to implements all fragments in the MainActivity like this:

public class MainActivity2 extends ActionBarActivity
        implements Fragment_A.OnFragmentInteractionListener, 
                   Fragment_B.OnFragmentInteractionListener, 
                   NavigationDrawerFragment.NavigationDrawerCallbacks {
    //rest code is omitted

    @Override
    public void onFragmentInteraction(Uri uri){
        //you can leave it empty
    }
}

P.S.: In short, this method could be used for communicating between fragments. For those of you who want to know more about this method, please refer to this link.

Try this mate, you can chuck it in the body like so...

    [HttpPost]
    [Route("~/API/ChangeTheNameIfNeeded")]
    public bool SampleCall([FromBody]JObject data)

        var firstName = data["firstName"].ToString();
        var lastName= data["lastName"].ToString();
        var email = data["email"].ToString();
        var obj= data["toLastName"].ToObject<SomeObject>();

        return _someService.DoYourBiz(firstName, lastName, email, obj);
    }

Here is a simple solution

try adding this dependency

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.3</version>
</dependency>

For completeness, I'm posting a version of the toMapOfNullables with a mergeFunction param:

public static <T, K, U> Collector<T, ?, Map<K, U>> toMapOfNullables(Function<? super T, ? extends K> keyMapper, Function<? super T, ? extends U> valueMapper, BinaryOperator<U> mergeFunction) {
    return Collectors.collectingAndThen(Collectors.toList(), list -> {
        Map<K, U> result = new HashMap<>();
        for(T item : list) {
            K key = keyMapper.apply(item);
            U newValue = valueMapper.apply(item);
            U value = result.containsKey(key) ? mergeFunction.apply(result.get(key), newValue) : newValue;
            result.put(key, value);
        }
        return result;
    });
}

In my case I was needed update the std=c++

I mean in my gradle file was this

android {
    ...

    defaultConfig {
        ...

        externalNativeBuild {
            cmake {
                cppFlags "-std=c++11", "-Wall"
                arguments "-DANDROID_STL=c++_static",
                        "-DARCORE_LIBPATH=${arcore_libpath}/jni",
                        "-DARCORE_INCLUDE=${project.rootDir}/app/src/main/libs"
            }
        }
       ....
    }

I changed this line

android {
    ...

    defaultConfig {
        ...

        externalNativeBuild {
            cmake {
                cppFlags "-std=c++17", "-Wall"   <-- this number from 11 to 17 (or 14)
                arguments "-DANDROID_STL=c++_static",
                        "-DARCORE_LIBPATH=${arcore_libpath}/jni",
                        "-DARCORE_INCLUDE=${project.rootDir}/app/src/main/libs"
            }
        }
       ....
    }

That's it...

Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.

I think you can use this

$("ul li:nth-child(2)").append("<span> - 2nd!</span>");

It finds the second li in each matched ul and notes it.

var obj = {name: 'Krishna', gender: 'male'};
angular.forEach(obj, function(value, key) {
    console.log(key + ': ' + value);
});

yields the attributes of obj with their respective values:

name: Krishna
gender: male

Using can also use Java 8 stream API and do the same thing in one line.

If you want to print any specific property then use this syntax:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> System.out.println(room.getName()));

OR

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> {
    // here room is available
});

if you want to print all the properties of Java object then use this:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(System.out::println);

Try something like this

PdfPCell cell;
PdfPTable tableHeader;
PdfPTable tmpTable;
PdfPTable table = new PdfPTable(10) { WidthPercentage = 100, RunDirection = PdfWriter.RUN_DIRECTION_LTR, ExtendLastRow = false };

// row 1 / cell 1 (merge)
PdfPCell _c = new PdfPCell(new Phrase("SER. No")) { Rotation = -90, VerticalAlignment = Element.ALIGN_MIDDLE, HorizontalAlignment = Element.ALIGN_CENTER, BorderWidth = 1 };
_c.Rowspan = 2;

table.AddCell(_c);

// row 1 / cell 2
_c = new PdfPCell(new Phrase("TYPE OF SHIPPING")) { VerticalAlignment = Element.ALIGN_MIDDLE, HorizontalAlignment = Element.ALIGN_CENTER };

You might need to re-adjust slightly on the widths and borders but that is a one shot to do.

You can use

insert into <table_name> select <fieldlist> from <tables>

Add a reference to Microsoft.JScript in your application in your web.config as below :

I had the same error in my case was when I needed to update jdk 7 to jdk 8, and my bad was just I installed jdk8 and I never installed jre8, only that, the error was solved immediately when I installed jre8.

Filezilla is great and it can support command line arguments.

Using Encoding.Unicode won't accurately decode an ANSI file in the same way that a JPEG decoder won't understand a GIF file.

I'm surprised that Encoding.Default didn't work for the ANSI file if it really was ANSI - if you ever find out exactly which code page Notepad was using, you could use Encoding.GetEncoding(int).

In general, where possible I'd recommend using UTF-8.

another way to access a column by number is to use a mapping dictionary where the key is the column name and the value is the column number

dates = pd.date_range('1/1/2000', periods=8)

df = pd.DataFrame(np.random.randn(8, 4),
   index=dates, columns=['A', 'B', 'C', 'D'])
print(df)
dct={'A':0,'B':1,'C':2,'D':3}
columns=df.columns

print(df.iloc[:,dct['D']])

For me the issue was updating psql apt-get wasn't resolving newer versions, even after update. The following worked.

Ubuntu

Start with the import of the GPG key for PostgreSQL packages.

sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

Now add the repository to your system.

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'

Install PostgreSQL on Ubuntu

sudo apt-get update
sudo apt-get install postgresql postgresql-contrib

https://www.postgresql.org/download/linux/ubuntu/

in.close();
scannerObject.close(); 

It will close Scanner and shut the warning.

I had the same issue. I had to provide the full path using Windows conventions. At this step:

Enter file in which to save the key (/c/Users/Eva/.ssh/id_rsa):

Provide the following value:

c:\users\eva\.ssh\id_rsa

There may be multiple ways to count the tables of a database. My favorite is this on:

SELECT
    COUNT(*)
FROM
    `information_schema`.`tables`
WHERE
    `table_schema` = 'my_database_name'
;

If you don't want to assign identifier to the hidden field; you can use name or class with selector like:

$('input[name=hiddenfieldname]').val();

or with assigned class:

$('input.hiddenfieldclass').val();

I've finally found the solution. Victor was close with the doc data.

const racesCollection: AngularFirestoreCollection<Race>;
return racesCollection.snapshotChanges().map(actions => {       
  return actions.map(a => {
    const data = a.payload.doc.data() as Race;
    data.id = a.payload.doc.id;
    return data;
  });
});

ValueChanges() doesn't include metadata, therefor we must use SnapshotChanges() when we require the document id and then map it properly as stated here https://github.com/angular/angularfire2/blob/master/docs/firestore/collections.md

Short answer: Don't do it.

Longer answer: Use WCF. It's here to replace Asmx.

see this answer for example, or the first comment on this one.

John Saunders: ASMX is a legacy technology, and should not be used for new development. WCF or ASP.NET Web API should be used for all new development of web service clients and servers. One hint: Microsoft has retired the ASMX Forum on MSDN.

As for comment ... well, if you have to, you have to. I'll leave you in the competent hands of the other answers then. (Even though it's funny it has issues, and if it does, why are you doing it in VS2013 to begin with ?)

WARNING:

The syntax list(groupby(...)) won't work the way that you intend. It seems to destroy the internal iterator objects, so using

for x in list(groupby(range(10))):
    print(list(x[1]))

will produce:

[]
[]
[]
[]
[]
[]
[]
[]
[]
[9]

Instead, of list(groupby(...)), try [(k, list(g)) for k,g in groupby(...)], or if you use that syntax often,

def groupbylist(*args, **kwargs):
    return [(k, list(g)) for k, g in groupby(*args, **kwargs)]

and get access to the groupby functionality while avoiding those pesky (for small data) iterators all together.

(Partially inspired by the good core logic of Equiman earlier in this thread.)

sessionExpiration.js

sessionExpiration.js is lightweight yet effective and customizable. Once implemented, use in just one row:

sessionExpiration(idleMinutes, warningMinutes, logoutUrl);

• Affects all tabs of the browser, not just one.
• Written in pure JavaScript, with no dependencies. Fully client side.
• (If so wanted.) Has warning banner and countdown clock, that is cancelled by user interaction.
• Simply include the sessionExpiration.js, and call the function, with arguments [1] number of idle minutes (across all tabs) until user is logged out, [2] number of idle minutes until warning and countdown is displayed, and [3] logout url.
• Put the CSS in your stylesheet. Customize it if you like. (Or skip and delete banner if you don't want it.)
• If you do want the warning banner however, then you must put an empty div with ID sessExpirDiv on your page (a suggestion is putting it in the footer).
• Now the user will be logged out automatically if all tabs have been inactive for the given duration.
• Optional: You may provide a fourth argument (URL serverRefresh) to the function, so that a server side session timer is also refreshed when you interact with the page.

This is an example of what it looks like in action, if you don't change the CSS.

Please find below the working solution for Windows:

1. Open Control Panel from the Start menu.
2. Select User Accounts.
3. Select the "Credential Manager".
4. Click on "Manage Windows Credentials".
5. Delete any credentials related to Git or GitHub.
6. Once you deleted all then try to clone again.

CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.

1. go to command prompt, and run as Administrator
2. in c:/> prompt -> pip install openpyxl
3. once you run in CMD you will get message like, Successfully installed et-xmlfile-1.0.1 jdcal-1.4.1 openpyxl-3.0.5
4. go to python interactive shell and run openpyxl module
5. openpyxl will work

One of the reasons is testability. Say you have this class:

interface HttpLoader {
    String load(String url);
}
interface StringOutput {
    void print(String txt);
}
@Component
class MyBean {
    @Autowired
    MyBean(HttpLoader loader, StringOutput out) {
        out.print(loader.load("http://stackoverflow.com"));
    }
}

How can you test this bean? E.g. like this:

class MyBeanTest {
    public void creatingMyBean_writesStackoverflowPageToOutput() {
        // setup
        String stackOverflowHtml = "dummy";
        StringBuilder result = new StringBuilder();

        // execution
        new MyBean(Collections.singletonMap("https://stackoverflow.com", stackOverflowHtml)::get, result::append);

        // evaluation
        assertEquals(result.toString(), stackOverflowHtml);
    }
}

Easy, right?

While you still depend on Spring (due to the annotations) you can remove you dependency on spring without changing any code (only the annotation definitions) and the test developer does not need to know anything about how spring works (maybe he should anyway, but it allows to review and test the code separately from what spring does).

It is still possible to do the same when using the ApplicationContext. However then you need to mock ApplicationContext which is a huge interface. You either need a dummy implementation or you can use a mocking framework such as Mockito:

@Component
class MyBean {
    @Autowired
    MyBean(ApplicationContext context) {
        HttpLoader loader = context.getBean(HttpLoader.class);
        StringOutput out = context.getBean(StringOutput.class);

        out.print(loader.load("http://stackoverflow.com"));
    }
}
class MyBeanTest {
    public void creatingMyBean_writesStackoverflowPageToOutput() {
        // setup
        String stackOverflowHtml = "dummy";
        StringBuilder result = new StringBuilder();
        ApplicationContext context = Mockito.mock(ApplicationContext.class);
        Mockito.when(context.getBean(HttpLoader.class))
            .thenReturn(Collections.singletonMap("https://stackoverflow.com", stackOverflowHtml)::get);
        Mockito.when(context.getBean(StringOutput.class)).thenReturn(result::append);

        // execution
        new MyBean(context);

        // evaluation
        assertEquals(result.toString(), stackOverflowHtml);
    }
}

This is quite a possibility, but I think most people would agree that the first option is more elegant and makes the test simpler.

The only option that is really a problem is this one:

@Component
class MyBean {
    @Autowired
    MyBean(StringOutput out) {
        out.print(new HttpLoader().load("http://stackoverflow.com"));
    }
}

Testing this requires huge efforts or your bean is going to attempt to connect to stackoverflow on each test. And as soon as you have a network failure (or the admins at stackoverflow block you due to excessive access rate) you will have randomly failing tests.

So as a conclusion I would not say that using the ApplicationContext directly is automatically wrong and should be avoided at all costs. However if there are better options (and there are in most cases), then use the better options.

If you use kotlin, this can be simplified by creating an extension function

fun View.setMarginExtensionFunction(left: Int, top: Int, right: Int, bottom: Int) {
  val params = layoutParams as ViewGroup.MarginLayoutParams
  params.setMargins(left, top, right, bottom)
  layoutParams = params
}

Now all you need is a view, and this extension function can be used anywhere.

val imageView = findViewById(R.id.imageView)
imageView.setMarginExtensionFunction(0, 0, 0, 0)

You can't change the margin of a table cell. But you CAN change the padding. Change the padding of the TD, which will make the cell larger and push the text away from the side with the increased padding. If you have border lines, however, it still won't be exactly what you want.

The biggest difference are the enterprise services (hence the ee) such as an application server supporting EJBs etc.

Just look at setAccessible() method used to access private fields and methods:

https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/AccessibleObject.html#setAccessible-boolean-

https://docs.oracle.com/javase/9/docs/api/java/lang/reflect/AccessibleObject.html#setAccessible-boolean-

Now there is a lot more conditions required for this method to work. The only reason it doesn't break almost all of older software is that modules autogenerated from plain JARs are very permissive (open and export everything for everyone).

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.

I just tested (should have done that first), and something like ng-show="!a && b" worked as expected.

Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:

All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.

This restriction accomplishes four functions, 1st and 3rd are important in this particular case:

• 1st: it removes any need for the connectors to retain application state between requests, thus reducing consumption of physical resources and improving scalability;
• 3rd: it allows an intermediary to view and understand a request in isolation, which may be necessary when services are dynamically rearranged;

And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.

One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.

There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:

• Authenticating REST Requests for Amazon Simple Storage Service (Amazon S3)
• Answer by Mauriceless on quiestion: "How to implement HMAC Authentication in a RESTful WCF API"
• crypto-js: JavaScript implementations of standard and secure cryptographic algorithms

How it works in practice

If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.

Hope this will helps you to find the proper solution!

Objective-C:
self.navigationItem.hidesBackButton = YES;

Swift:
navigationItem.hidesBackButton = true

I am including this answer in case someone comes to this page for the same reason I did. I just wasted an embarrassing amount of time trying to track the problem down. I was calling:

unset($_SESSION['myVar']);

from a logout script. Then navigating to a page that required login, and the server still thought I was logged in. The problem was that the logout script was not calling:

session_start();

Unsetting a session var DOES NOT WORK unless you start the session first.

I know this question has far too many answers already, but none of them met my exact requirements.

I wanted a function that has the exact opposite behavior of parentNode.insertBefore - that is, it must accept a null referenceNode (which the accepted answer does not) and where insertBefore would insert at the end of the children this one must insert at the start, since otherwise there'd be no way to insert at the start location with this function at all; the same reason insertBefore inserts at the end.

Since a null referenceNode requires you to locate the parent, we need to know the parent - insertBefore is a method of the parentNode, so it has access to the parent that way; our function doesn't, so we'll need to pass the parent as a parameter.

The resulting function looks like this:

function insertAfter(parentNode, newNode, referenceNode) {
  parentNode.insertBefore(
    newNode,
    referenceNode ? referenceNode.nextSibling : parentNode.firstChild
  );
}

Or (if you must, I don't recommend it) you can of course enhance the Node prototype:

if (! Node.prototype.insertAfter) {
  Node.prototype.insertAfter = function(newNode, referenceNode) {
    this.insertBefore(
      newNode,
      referenceNode ? referenceNode.nextSibling : this.firstChild
    );
  };
}

Step-1 Need to find user details by using below query

SQL> select username, account_status from dba_users where username='BOB';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            EXPIRED

Step-2 Get users password by using below query.

SQL>SELECT 'ALTER USER '|| name ||' IDENTIFIED BY VALUES '''|| spare4 ||';'|| password ||''';' FROM sys.user$ WHERE name='BOB';

ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';

Step -3 Run Above alter query

SQL> ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';
User altered.

Step-4 :Check users account status

SQL> select username, account_status from dba_users where username='BOB';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            OPEN

Strangely, for the exact same issue, what helped me was changing the ' to 'v11.0' in the following section of the config.

<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>

In this code you just need to call this in your button click.

private void list_paired_Devices() {
        Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
        ArrayList<String> devices = new ArrayList<>();
        for (BluetoothDevice bt : pairedDevices) {
            devices.add(bt.getName() + "\n" + bt.getAddress());
        }
        ArrayAdapter arrayAdapter = new ArrayAdapter(bluetooth.this, android.R.layout.simple_list_item_1, devices);
        emp.setAdapter(arrayAdapter);
    }

OK, so I don't really know what the problem was, but I simply fixed it by navigating to here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and installing 8u74 instead of 8u73 which is what I was prompted to do when I would go to "download latest version" in Java. So changing the versions is what did it in the end. Eclipse launched fine, now. Thanks for everyone's help!

edit: Apr 2018- Now is 8u161 and 8u162 (Just need one, I used 8u162 and it worked.)

You just need to post the form data to the insert php file function, see below :)

class DbConnect
{
// Database login vars
private $dbHostname = '';
private $dbDatabase = '';
private $dbUsername = '';
private $dbPassword = '';
public $db = null;

public function connect()
{

    try
    {
        $this->db = new PDO("mysql:host=".$this->dbHostname.";dbname=".$this->dbDatabase, $this->dbUsername, $this->dbPassword);
        $this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }
    catch(PDOException $e)
    {
        echo "It seems there was an error.  Please refresh your browser and try again. ".$e->getMessage();
    }
}

public function store($email)
{
    $stm = $this->db->prepare('INSERT INTO subscribers (email) VALUES ?');
    $stm->bindValue(1, $email);

    return $stm->execute();
}
}

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

Since performance.navigation is now deprecated, you can try this:

var perfEntries = performance.getEntriesByType("navigation");

if (perfEntries[0].type === "back_forward") {
    location.reload(true);
}

Change into the directory and;

attrib.exe /s ./*.* |find /c /v ""

EDIT

I presumed that would be simple to discover. use

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "batchfile.bat";
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();

I run this and the variable output was holding this

D:\VSS\USSD V3.0\WTU.USSD\USSDConsole\bin\Debug>attrib.exe /s ./*.*   | find /c /v "" 13

where 13 is the file count. It should solve the issue

For

<%=clients%>

to work you need to have a public or protected variable clients in the code-behind.

Here is an article that explains it: http://msdn.microsoft.com/en-us/library/6c3yckfw.aspx

SELECT
main.CustomerID,
f.Data AS FirstName,
m.Data AS MiddleName,
l.Data AS LastName,
d.Data AS Date
FROM table main
INNER JOIN table f on f.CustomerID = main.CustomerID
INNER JOIN table m on m.CustomerID = main.CustomerID
INNER JOIN table l on l.CustomerID = main.CustomerID
INNER JOIN table d on d.CustomerID = main.CustomerID
WHERE f.DBColumnName = 'FirstName' 
AND m.DBColumnName = 'MiddleName' 
AND l.DBColumnName = 'LastName' 
AND d.DBColumnName = 'Date' 

Edit: I have written this without an editor & have not run the SQL. I hope, you get the idea.

Updated with Swift 5 Generally we use three type of Local Notifications

1. Simple Local Notification
2. Local Notification with Action
3. Local Notification with Content

Where you can send simple text notification or with action button and attachment.

Using UserNotifications package in your app, the following example Request for notification permission, prepare and send notification as per user action AppDelegate itself, and use view controller listing different type of local notification test.

AppDelegate

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    let notificationCenter = UNUserNotificationCenter.current()
    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        //Confirm Delegete and request for permission
        notificationCenter.delegate = self
        let options: UNAuthorizationOptions = [.alert, .sound, .badge]
        notificationCenter.requestAuthorization(options: options) {
            (didAllow, error) in
            if !didAllow {
                print("User has declined notifications")
            }
        }

        return true
    }

    func applicationWillResignActive(_ application: UIApplication) {
    }
    func applicationDidEnterBackground(_ application: UIApplication) {
    }
    func applicationWillEnterForeground(_ application: UIApplication) {
    }
    func applicationWillTerminate(_ application: UIApplication) {
    }
    func applicationDidBecomeActive(_ application: UIApplication) {
        UIApplication.shared.applicationIconBadgeNumber = 0
    }


    //MARK: Local Notification Methods Starts here

    //Prepare New Notificaion with deatils and trigger
    func scheduleNotification(notificationType: String) {

        //Compose New Notificaion
        let content = UNMutableNotificationContent()
        let categoryIdentifire = "Delete Notification Type"
        content.sound = UNNotificationSound.default
        content.body = "This is example how to send " + notificationType
        content.badge = 1
        content.categoryIdentifier = categoryIdentifire

        //Add attachment for Notification with more content
        if (notificationType == "Local Notification with Content")
        {
            let imageName = "Apple"
            guard let imageURL = Bundle.main.url(forResource: imageName, withExtension: "png") else { return }
            let attachment = try! UNNotificationAttachment(identifier: imageName, url: imageURL, options: .none)
            content.attachments = [attachment]
        }

        let identifier = "Local Notification"
        let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)

        notificationCenter.add(request) { (error) in
            if let error = error {
                print("Error \(error.localizedDescription)")
            }
        }

        //Add Action button the Notification
        if (notificationType == "Local Notification with Action")
        {
            let snoozeAction = UNNotificationAction(identifier: "Snooze", title: "Snooze", options: [])

    var appDelegate = UIApplication.shared.delegate as? AppDelegate
    let notifications = ["Simple Local Notification",
                         "Local Notification with Action",
                         "Local Notification with Content",]

        }
        alert.addAction(okAction)
        present(alert, animated: true, completion: nil)
    }
}

You can use urllib2

import urllib2
content = urllib2.urlopen(some_url).read()
print content

Also you can use httplib

import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("HEAD","/index.html")
res = conn.getresponse()
print res.status, res.reason
# Result:
200 OK

or the requests library

import requests
r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
r.status_code
# Result:
200

it makes the assignment visible to subprocesses.

$ foo=bar
$ bash -c 'echo $foo'

$ export foo
$ bash -c 'echo $foo'
bar

To get a decimal with 2 numbers after the comma, you could just use:

function nformat(a) {
   var b = parseInt(parseFloat(a)*100)/100;
   return b.toFixed(2);
}

• System properties are set on the Java command line using the -Dpropertyname=value syntax. They can also be added at runtime using System.setProperty(String key, String value) or via the various System.getProperties().load() methods.
  To get a specific system property you can use System.getProperty(String key) or System.getProperty(String key, String def).

• Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername or on Windows SET WINDIR=C:\Windows etc, and, unlike properties, may not be set at runtime.
  To get a specific environment variable you can use System.getenv(String name).

Zalgo text works because of combining characters. These are special characters that allow to modify character that comes before.

OR

y + ̆ = y̆ which actually is

y + ̆ = y̆

Since you can stack them one atop the other you can produce the following:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

which actually is:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

The same goes for putting stuff underneath:

y̰̰̰̰̰̰̰̰̰̰̰̰̰̰̰̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

that in fact is:

y̰̰̰̰̰̰̰̰̰̰̰̰̰̰̰̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

In Unicode, the main block of combining diacritics for European languages and the International Phonetic Alphabet is U+0300–U+036F.

More about it here

To produce a list of combining diacritical marks you can use the following script (since links keep on dying)

for(var i=768; i<879; i++){console.log(new DOMParser().parseFromString("&#"+i+";", "text/html").documentElement.textContent +"  "+"&#"+i+";");}

To navigate to another component you can use this.props.history.push('/main');

import React, { Component, Fragment } from 'react'

class Example extends Component {

  redirect() {
    this.props.history.push('/main')
  }

  render() {
    return (
      <Fragment>
        {this.redirect()}
      </Fragment>
    );
   }
 }

 export default Example

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

Fluent API

public class SchoolContext : DbContext
{
    public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

DBQuery.shellBatchSize = 300

will do.

MongoDB Docs - Configure the mongo Shell - Change the mongo Shell Batch Size

the third parameter should be like array('selected' =>value)

The MyKey class (@Embeddable) should not have any relationships like @ManyToOne

The easiest way to do it is to use the End method, which is gives you the cell that you reach by pressing the end key and then a direction when you're on a cell (in this case B6). This won't give you what you expect if B6 or B7 is empty, though.

Dim start_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Range(start_cell, start_cell.End(xlDown)).Copy Range("[Workbook2.xlsx]Sheet1!A2")

If you can't use End, then you would have to use a loop.

Dim start_cell As Range, end_cell As Range

Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Set end_cell = start_cell

Do Until IsEmpty(end_cell.Offset(1, 0))
    Set end_cell = end_cell.Offset(1, 0)
Loop

Range(start_cell, end_cell).Copy Range("[Workbook2.xlsx]Sheet1!A2")

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

<div style="height: 100px;"> </div>

OR

<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px;  }

const is similar to static we can access both varables with class name but diff is static variables can be modified and const can not.

To set the disabled to false using the name property of the input:

document.myForm.myInputName.disabled = false;

The 3rd option is to create a "Policy" table, then a "SectionsMain" table that stores all of the fields that are in common across the types of sections. Then create other tables for each type of section that only contain the fields that are not in common.

Deciding which is best depends mostly on how many fields you have and how you want to write your SQL. They would all work. If you have just a few fields then I would probably go with #1. With "lots" of fields I would lean towards #2 or #3.

document.oncontextmenu = function() {return false;}; //disable the browser context menu
$('selector-name')[0].oncontextmenu = function(){} //set jquery element context menu 

you can use map function. this is worked for me.

db.Sensors
    .findAll({
        where: { nodeid: node.nodeid }
     })
    .map(el => el.get({ plain: true }))
    .then((rows)=>{
        response.json( rows )
     });

Here is a full example, I hope it helps =).

<!DOCTYPE html>

    }
</script>

install aria2c in system &

 echo exec("aria2c \"$url\"")

It works for me by using require syntax like this:

$('.eventSlick').slick({
    dots: true,
    slidesToShow: 3,
    slidesToScroll: 1,
    autoplay: false,
    autoplaySpeed: 2000,
    arrows: true,
    draggable: false,
    prevArrow: '<button type="button" data-role="none" class="slick-prev"><img src="' + require("@/assets/img/icon/Arrow_Left.svg")+'"></button>',

If you have GNU extensions, you can use sed's \L (lower entire match, or until \L [lower] or \E [end - toggle casing off] is reached), like so:

sed 's/.*/\L&/' <input >output

Note: '&' means the full match pattern.

As a side note, GNU extensions include \U (upper), \u (upper next character of match), \l (lower next character of match). For example, if you wanted to camelcase a sentence:

$ sed -r 's/\w+/\u&/g' <<< "Now is the time for all good men..." # Camel Case
Now Is The Time For All Good Men...

Note: Since the assumption is we have GNU extensions, we can also use the dash-r (extended regular expressions) option, which allows \w (word character) and relieves you of having to escape the capturing parenthesis and one-or-more quantifier (+). (Aside: \W [non-word], \s [whitespace], \S [non-whitespace] are also supported with dash-r, but \d [digit] and \D [non-digit] are not.)

You need to wrap you image source path within {}

<img src={'path/to/one.jpeg'} />

You need to use require if using webpack

<img src={require('path/to/one.jpeg')} />

If you are using fish shell. Then all the variables can be set in .config/fish/config.fish

vim .config/fish/config.fish

Add the following lines

set -g JAVA_HOME "your_path_to_jdk"

save and exit out of vim.

This should be setting your JAVA_HOME. Thanks

CSS selection and applying style to a particular element can be done through traversing through the dom element [Example

Example

.a .b .c .d{
    background: #bdbdbd;
}
div>div>div>div:last-child{
    background: red;
}

<div class='a'>The first paragraph.
 <div class='b'>The second paragraph.
  <div class='c'>The third paragraph.
   <div class='d'>The fourth paragraph.</div>
   <div class='e'>The fourth paragraph.</div>
  </div>
 </div>
</div>

This doesn't say how to "fix" the problem - that's already been done in other answers; it exists to draw out the details and applicable documentation references.

When using String.replaceAll or any of the applicable Matcher replacers, pay attention to the replacement string and how it is handled:

Note that backslashes (\) and dollar signs ($) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string. Dollar signs may be treated as references to captured subsequences as described above, and backslashes are used to escape literal characters in the replacement string.

As pointed out by isnot2bad in a comment, Matcher.quoteReplacement may be useful here:

Returns a literal replacement String for the specified String. .. The String produced will match the sequence of characters in s treated as a literal sequence. Slashes (\) and dollar signs ($) will be given no special meaning.

the bottom cell will grow as you enter more text ... setting the table width will help too

Based on my experience with AngularJS modals so far I believe that the most elegant approach is a dedicated service to which we can provide a partial (HTML) template to be displayed in a modal.

When we think about it modals are kind of AngularJS routes but just displayed in modal popup.

The AngularUI bootstrap project (http://angular-ui.github.com/bootstrap/) has an excellent $modal service (used to be called $dialog prior to version 0.6.0) that is an implementation of a service to display partial's content as a modal popup.

We cannot prevent the status appearing in full screen mode in (4.4+) kitkat or above devices, so try a hack to block the status bar from expanding.

Solution is pretty big, so here's the link of SO:

StackOverflow : Hide status bar in android 4.4+ or kitkat with Fullscreen

It avoids a full shuffle. If it's known that the number is decreasing then the executor can safely keep data on the minimum number of partitions, only moving the data off the extra nodes, onto the nodes that we kept.

So, it would go something like this:

Node 1 = 1,2,3
Node 2 = 4,5,6
Node 3 = 7,8,9
Node 4 = 10,11,12

Then coalesce down to 2 partitions:

Node 1 = 1,2,3 + (10,11,12)
Node 3 = 7,8,9 + (4,5,6)

Notice that Node 1 and Node 3 did not require its original data to move.

Put it all in one document and use this:

This did not require any TechNet rigamarole or the use of their horrible Java 7 based download manager.

PHP will let you build the pages of your site that make up your video conferencing and chat applications, but it won't deliver or stream video for you - PHP runs on the server only and renders out HTML to a client browser.

For the video, the first thing you'll need is a live streaming account with someone like akamai or the numerous others in the field. Using this account gives you an ingress point for your video - ie: the server that you will stream your live video up to.

Next, you want to get your video out to the browsers - windows media player, flash or silverlight will let you achieve this - embedding the appropriate control for your chosen technology into your page (using PHP or whatever) and given the address of your live video feed.

PHP (or other scripting language) would be used to build the chat part of the application and bring the whole thing together (the chat and the embedded video player).

Hope this helps.

A pure Python equivalent for string comparisons would be:

def less(string1, string2):
    # Compare character by character
    for idx in range(min(len(string1), len(string2))):
        # Get the "value" of the character
        ordinal1, ordinal2 = ord(string1[idx]), ord(string2[idx])
        # If the "value" is identical check the next characters
        if ordinal1 == ordinal2:
            continue
        # It's not equal so we're finished at this index and can evaluate which is smaller.
        else:
            return ordinal1 < ordinal2
    # We're out of characters and all were equal, so the result depends on the length
    # of the strings.
    return len(string1) < len(string2)

This function does the equivalent of the real method (Python 3.6 and Python 2.7) just a lot slower. Also note that the implementation isn't exactly "pythonic" and only works for < comparisons. It's just to illustrate how it works. I haven't checked if it works like Pythons comparison for combined unicode characters.

A more general variant would be:

from operator import lt, gt

def compare(string1, string2, less=True):
    op = lt if less else gt
    for char1, char2 in zip(string1, string2):
        ordinal1, ordinal2 = ord(char1), ord(char1)
        if ordinal1 == ordinal2:
            continue
        else:
            return op(ordinal1, ordinal2)
    return op(len(string1), len(string2))

if for some reasons you don't have permission to use

vagrant plugin install vagrant-scp

there is an alternative way :

First vagrant up yourVagrantProject, then write in the terminal :

vagrant ssh-config

you will have informations about "HostName" and "Port" of your virtual machine.

In some case, you could have some virtual machines in your project. So just find your master-machine (in general, this VM has the port 2222 ), and don't pay attention to others machines informations.

write the command to make the copy :

scp -P xxPortxx  /Users/where/is/your/file.txt  vagrant@xxHostNamexx:/home/vagrant

At this steep you will have to put a vagrant password : by default it's "vagrant"

after that if you look at files in your virtual machine:

vagrant ssh xxVirtualMachineNamexx
pwd
ls

you will have the "file.txt" in your virtual machine directory

Try

make clean
./configure --with-option=/path/etc
make && make install

Thinking of things that actually need a stack:

If we consider the pattern of recursion as:

if(task can be done directly) {
    return result of doing task directly
} else {
    split task into two or more parts
    solve for each part (possibly by recursing)
    return result constructed by combining these solutions
}

For example, the classic Tower of Hanoi

if(the number of discs to move is 1) {
    just move it
} else {
    move n-1 discs to the spare peg
    move the remaining disc to the target peg
    move n-1 discs from the spare peg to the target peg, using the current peg as a spare
}

This can be translated into a loop working on an explicit stack, by restating it as:

place seed task on stack
while stack is not empty 
   take a task off the stack
   if(task can be done directly) {
      Do it
   } else {
      Split task into two or more parts
      Place task to consolidate results on stack
      Place each task on stack
   }
}

For Tower of Hanoi this becomes:

stack.push(new Task(size, from, to, spare));
while(! stack.isEmpty()) {
    task = stack.pop();
    if(task.size() = 1) {
        just move it
    } else {
        stack.push(new Task(task.size() -1, task.spare(), task,to(), task,from()));
        stack.push(new Task(1, task.from(), task.to(), task.spare()));
        stack.push(new Task(task.size() -1, task.from(), task.spare(), task.to()));
    }
}

There is considerable flexibility here as to how you define your stack. You can make your stack a list of Command objects that do sophisticated things. Or you can go the opposite direction and make it a list of simpler types (e.g. a "task" might be 4 elements on a stack of int, rather than one element on a stack of Task).

All this means is that the memory for the stack is in the heap rather than in the Java execution stack, but this can be useful in that you have more control over it.

I got the same problem while running unit tests. I found this workaround solution:

The following workaround allows to get rid of this message:

    File workaround = new File(".");
    System.getProperties().put("hadoop.home.dir", workaround.getAbsolutePath());
    new File("./bin").mkdirs();
    new File("./bin/winutils.exe").createNewFile();

Step-by-step answer similar to the one you refer to, using the new cv2 Python bindings:

1. Read a grayscale image

import cv2
im_gray = cv2.imread('grayscale_image.png', cv2.IMREAD_GRAYSCALE)

2. Convert grayscale image to binary

(thresh, im_bw) = cv2.threshold(im_gray, 128, 255, cv2.THRESH_BINARY | cv2.THRESH_OTSU)

which determines the threshold automatically from the image using Otsu's method, or if you already know the threshold you can use:

thresh = 127
im_bw = cv2.threshold(im_gray, thresh, 255, cv2.THRESH_BINARY)[1]

3. Save to disk

cv2.imwrite('bw_image.png', im_bw)

New, resurrected project site (Win7 compability and more!): http://sshwindows.sourceforge.net

1st January 2012

• OpenSSH for Windows 5.6p1-2 based release created!!
• Happy New Year all! Since COpSSH has started charging I've resurrected this project
• Updated all binaries to current releases
• Added several new supporting DLLs as required by all executables in package
• Renamed switch.exe to bash.exe to remove the need to modify and compile mkpasswd.exe each build
• Please note there is a very minor bug in this release, detailed in the docs. I'm working on fixing this, anyone who can code in C and can offer a bit of help it would be much appreciated

I like the idea of Chasmo, but I preffer to use the advantages of things like

convert $(ls *.pdf) ../merged.pdf

Giving multiple source files to convert leads to merging them into a common pdf. This command merges all files with .pdfextension in the actual directory into merged.pdf in the parent dir.

With the nuget package System.Resources.ResourceManager (v4.3.0) the ResourceSet and ResourceManager.GetResourceSet are not available.

Using the ResourceReader, as this post suggest: "C# - Cannot getting a string from ResourceManager (from satellite assembly)"

It's still possible to read the key/values of the resource file.

System.Reflection.Assembly resourceAssembly = System.Reflection.Assembly.Load(new System.Reflection.AssemblyName("YourAssemblyName"));
String[] manifests = resourceAssembly.GetManifestResourceNames(); 
using (ResourceReader reader = new ResourceReader(resourceAssembly.GetManifestResourceStream(manifests[0])))
{
   System.Collections.IDictionaryEnumerator dict = reader.GetEnumerator();
   while (dict.MoveNext())
   {
      String key = dict.Key as String;
      String value = dict.Value as String;
   }
}

kubectl rollout restart deployment myapp

This is the current way to trigger a rolling update and leave the old replica sets in place for other operations provided by kubectl rollout like rollbacks.

Here's a solution without map, 'checked' properties and FormControl.

app.component.html:

<div *ngFor="let item of options">
  <input type="checkbox" 
  (change)="onChange($event.target.checked, item)"
  [checked]="checked(item)"
>
  {{item}}
</div>

app.component.ts:

  options = ["1", "2", "3", "4", "5"]
  selected = ["1", "2", "5"]

  // check if the item are selected
  checked(item){
    if(this.selected.indexOf(item) != -1){
      return true;
    }
  }

  // when checkbox change, add/remove the item from the array
  onChange(checked, item){
    if(checked){
    this.selected.push(item);
    } else {
      this.selected.splice(this.selected.indexOf(item), 1)
    }
  }

DEMO

Here's a special case where one of data field has semicolon (";") as part of it's data in that case most of answers above will fail.

Solution it that case will be

string[] csvRows = System.IO.File.ReadAllLines(FullyQaulifiedFileName);
string[] fields = null;
List<string> lstFields;
string field;
bool quoteStarted = false;
foreach (string csvRow in csvRows)
{
    lstFields = new List<string>();
    field = "";
    for (int i = 0; i < csvRow.Length; i++)
    {
        string tmp = csvRow.ElementAt(i).ToString();
        if(String.Compare(tmp,"\"")==0)
        {
            quoteStarted = !quoteStarted;
        }
        if (String.Compare(tmp, ";") == 0 && !quoteStarted)
        {
            lstFields.Add(field);
            field = "";
        }
        else if (String.Compare(tmp, "\"") != 0)
        {
            field += tmp;
        }
    }
    if(!string.IsNullOrEmpty(field))
    {
        lstFields.Add(field);
        field = "";
    }
// This will hold values for each column for current row under processing
    fields = lstFields.ToArray(); 
}

Use str.ljust():

>>> 'Hi'.ljust(6)
'Hi    '

You should also consider string.zfill(), str.ljust() and str.center() for string formatting. These can be chained and have the 'fill' character specified, thus:

>>> ('3'.zfill(8) + 'blind'.rjust(8) + 'mice'.ljust(8, '.')).center(40)
'        00000003   blindmice....        '

These string formatting operations have the advantage of working in Python v2 and v3.

Take a look at pydoc str sometime: there's a wealth of good stuff in there.

I was able to show/hide a menu this way:

MenuView.java (extends FrameLayout)

private final int ANIMATION_DURATION = 500;

public void showMenu()
{
    setVisibility(View.VISIBLE);
    animate()
            .alpha(1f)
            .setDuration(ANIMATION_DURATION)
            .setListener(null);
}

private void hideMenu()
{
    animate()
            .alpha(0f)
            .setDuration(ANIMATION_DURATION)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    setVisibility(View.GONE);
                }
            });
}

Source

simply add to your data structure ( mItems ) , and then notify your adapter about dataset change

private void addItem(String item) {
  mItems.add(item);
  mAdapter.notifyDataSetChanged();
}

addItem("New Item");

While the results vary in this case because the column names are numbers, another way I've used is data.frame(rbind(mytable)). Using the example from @X.X:

> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)

> freq_t
   gear
cyl  3  4  5
  4  1  8  2
  6  2  4  1
  8 12  0  2

> data.frame(rbind(freq_t))
  X3 X4 X5
4  1  8  2
6  2  4  1
8 12  0  2

If the column names do not start with numbers, the X won't get added to the front of them.

I see only one case that you would allow exposure to your internal members to another assembly and that is for testing purposes.

Saying that there is a way to allow "Friend" assemblies access to internals:

In the AssemblyInfo.cs file of the project you add a line for each assembly.

[assembly: InternalsVisibleTo("name of assembly here")]

this info is available here.

Hope this helps.

As stated by the other answers, you are adding the same array of rows to each column. To create a multidimensional array you must use a loop

var NumColumns = 27
var NumRows = 52
var array = Array<Array<Double>>()
for column in 0..NumColumns {
    array.append(Array(count:NumRows, repeatedValue:Double()))
}

Since strings are objects and since all objects in Java are always stored only in the heap space, all strings are stored in the heap space. However, Java keeps strings created without using the new keyword in a special area of the heap space, which is called "string pool". Java keeps the strings created using the new keyword in the regular heap space.

The purpose of the string pool is to maintain a set of unique strings. Any time you create a new string without using the new keyword, Java checks whether the same string already exists in the string pool. If it does, Java returns a reference to the same String object and if it does not, Java creates a new String object in the string pool and returns its reference. So, for example, if you use the string "hello" twice in your code as shown below, you will get a reference to the same string. We can actually test this theory out by comparing two different reference variables using the == operator as shown in the following code:

String str1 = "hello";
String str2 = "hello";
System.out.println(str1 == str2); //prints true

String str3 = new String("hello");
String str4 = new String("hello");

System.out.println(str1 == str3); //prints false
System.out.println(str3 == str4); //prints false 

== operator is simply checks whether two references point to the same object or not and returns true if they do. In the above code, str2 gets the reference to the same String object which was created earlier. However, str3 and str4 get references to two entirely different String objects. That is why str1 == str2 returns true but str1 == str3 and str3 == str4 return false . In fact, when you do new String("hello"); two String objects are created instead of just one if this is the first time the string "hello" is used in the anywhere in program - one in the string pool because of the use of a quoted string, and one in the regular heap space because of the use of new keyword.

String pooling is Java's way of saving program memory by avoiding the creation of multiple String objects containing the same value. It is possible to get a string from the string pool for a string created using the new keyword by using String's intern method. It is called "interning" of string objects. For example,

String str1 = "hello";
String str2 = new String("hello");
String str3 = str2.intern(); //get an interned string obj

System.out.println(str1 == str2); //prints false
System.out.println(str1 == str3); //prints true

As per the official documentation of the jquery sortable UI: http://api.jqueryui.com/sortable/#method-toArray

In update event. use:

var sortedIDs = $( ".selector" ).sortable( "toArray" );

and if you alert or console this var (sortedIDs). You'll get your sequence. Please choose as the "Right Answer" if it is a right one.

The base dn is dc=example,dc=com.

I don't know about openca, but I will try this answer since you got very little traffic so far.

A base dn is the point from where a server will search for users. So I would try to simply use admin as a login name.

If openca behaves like most ldap aware applications, this is what is going to happen :

1. An ldap search for the user admin will be done by the server starting at the base dn (dc=example,dc=com).
2. When the user is found, the full dn (cn=admin,dc=example,dc=com) will be used to bind with the supplied password.
3. The ldap server will hash the password and compare with the stored hash value. If it matches, you're in.

Getting step 1 right is the hardest part, but mostly because we don't get to do it often. Things you have to look out for in your configuraiton file are :

• The dn your application will use to bind to the ldap server. This happens at application startup, before any user comes to authenticate. You will have to supply a full dn, maybe something like cn=admin,dc=example,dc=com.
• The authentication method. It is usually a "simple bind".
• The user search filter. Look at the attribute named objectClass for your admin user. It will be either inetOrgPerson or user. There will be others like top, you can ignore them. In your openca configuration, there should be a string like (objectClass=inetOrgPerson). Whatever it is, make sure it matches your admin user's object Class. You can specify two object class with this search filter (|(objectClass=inetOrgPerson)(objectClass=user)).

Download an LDAP Browser, such as Apache's Directory Studio. Connect using your application's credentials, so you will see what your application sees.

    body
    {
        width:80%;
        margin-left:auto;
        margin-right:auto;
    }

This will work on most browsers, including IE.

In Informix, you can use:

RENAME COLUMN TableName.OldName TO NewName;

This was implemented before the SQL standard addressed the issue - if it is addressed in the SQL standard. My copy of the SQL 9075:2003 standard does not show it as being standard (amongst other things, RENAME is not one of the keywords). I don't know whether it is actually in SQL 9075:2008.

Promises are not callbacks, both are programming idioms that facilitate async programming. Using an async/await-style of programming using coroutines or generators that return promises could be considered a 3rd such idiom. A comparison of these idioms across different programming languages (including Javascript) is here: https://github.com/KjellSchubert/promise-future-task

The upcoming change is for chinese, arabic domain names not URIs. The internationalised URIs are called IRIs and are defined in RFC 3987. However, having said that I'd recommend not doing this yourself but relying on an existing, tested library since there are lots of choices of URI encoding/decoding and what are considered safe by specification, versus what are safe by actual use (browsers).

There is a css3 solution here if that is acceptable. It supports the graceful degradation approach where css3 isn't supported. you just won't have any transparency.

I used to have the same error when i change my user email by git config --global user.email and found my solution here: Go to: Control Panel -> User Accounts -> Manage your credentials -> Windows Credentials

Under Generic Credentials there are some credentials related to Github, Click on them and click "Remove".

and when you try to push something, you need to login again. hope this will be helpful for you

You could also do

   var x = $('#element').height();   // or any changing value

   $('selector').css({'top' : x + 'px'});

OR

You can use directly

$('#element').css( "height" )

The difference between .css( "height" ) and .height() is that the latter returns a unit-less pixel value (for example, 400) while the former returns a value with units intact (for example, 400px). The .height() method is recommended when an element's height needs to be used in a mathematical calculation. jquery doc

You can set TextBox properties for setting negative number display and decimal places settings.

1. Right-click the cell and then click Text Box Properties.
2. Select Number, and in the Category field, click Currency.

You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick.

This code doesn't involve compiler flags or direct runtime calls:

SEL selector = @selector(zeroArgumentMethod);
NSMethodSignature *methodSig = [[self class] instanceMethodSignatureForSelector:selector];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:methodSig];
[invocation setSelector:selector];
[invocation setTarget:self];
[invocation invoke];

NSInvocation allows multiple arguments to be set so unlike performSelector this will work on any method.

The answer was very funny for me and my team, and worked like a charm

• In the Interface Builder, Just move the tableview under another view in the view hierarchy.

REASON:

We observed that this happens only for the First View in the View Hierarchy, if this first view is a UITableView. So, all other similar UITableViews do not have this annoying section, except the first. We Tried moving the UITableView out of the first place in the view hierarchy, and everything was working as expected.

As you say, ordinal is a bit risky. Consider for example:

public enum Boolean {
    TRUE, FALSE
}

public class BooleanTest {
    @Test
    public void testEnum() {
        assertEquals(0, Boolean.TRUE.ordinal());
        assertEquals(1, Boolean.FALSE.ordinal());
    }
}

If you stored this as ordinals, you might have rows like:

> SELECT STATEMENT, TRUTH FROM CALL_MY_BLUFF

"Alice is a boy"      1
"Graham is a boy"     0

But what happens if you updated Boolean?

public enum Boolean {
    TRUE, FILE_NOT_FOUND, FALSE
}

This means all your lies will become misinterpreted as 'file-not-found'

Better to just use a string representation

Others have explained what NoneType is and a common way of ending up with it (i.e., failure to return a value from a function).

Another common reason you have None where you don't expect it is assignment of an in-place operation on a mutable object. For example:

mylist = mylist.sort()

The sort() method of a list sorts the list in-place, that is, mylist is modified. But the actual return value of the method is None and not the list sorted. So you've just assigned None to mylist. If you next try to do, say, mylist.append(1) Python will give you this error.

NuGet references

Assume the -Project_A (produces project_a.dll) -Project_B (produces project_b.dll) and Project_B references to Project_A by NuGet packages then just copy project_a.dll , project_a.pdb to the folder Project_B/Packages. In effect that should be copied to the /bin.

Now debug Project_A. When code reaches the part where you need to call dll's method or events etc while debugging, press F11 to step into the dll's code.

First, make sure you have the following address in your Environment Variables Path

C:\Program Files (x86)\Microsoft SDKs\TypeScript\2.0

Then open your Command Prompt and type the following command:

tsc -v

You cannot - a XSD describes the DATA aspects e.g. of a webservice - the WSDL describes the FUNCTIONS of the web services (method calls). You cannot typically figure out the method calls from your data alone.

These are really two separate, distinctive parts of the equation. For simplicity's sake you would often import your XSD definitions into the WSDL in the <wsdl:types> tag.

I had the very same issue, not being able to instantiate the type of a class which I was absolutely sure was not abstract. Turns out I was implementing an abstract class from Java.util instead of implementing my own class.

So if the previous answers did not help you, please check that you import the class you actually wanted to import, and not something else with the same name that you IDE might have hinted you.

For example, if you were trying to instantiate the class Queue from the package myCollections which you coded yourself :

import java.util.*; // replace this line
import myCollections.Queue; // by this line

     Queue<Edge> theQueue = new Queue<Edge>();

With a solution open, go to the Debug - Exceptions (Ctrl+D,E) menu option. From there you can choose to break on Thrown or User-unhandled exceptions.

Try to use Aspose.cells library (not free, but trial is enough to read), it is quite good

Install-package Aspose.cells

There is sample code:

using Aspose.Cells;
using System;

namespace ExcelReader
{
    class Program
    {
        static void Main(string[] args)
        {
            // Replace path for your file
            readXLS(@"C:\MyExcelFile.xls"); // or "*.xlsx"
            Console.ReadKey();
        }

        public static void readXLS(string PathToMyExcel)
        {
            //Open your template file.
            Workbook wb = new Workbook(PathToMyExcel);

            //Get the first worksheet.
            Worksheet worksheet = wb.Worksheets[0];

            //Get cells
            Cells cells = worksheet.Cells;

            // Get row and column count
            int rowCount = cells.MaxDataRow;
            int columnCount = cells.MaxDataColumn;

            // Current cell value
            string strCell = "";

            Console.WriteLine(String.Format("rowCount={0}, columnCount={1}", rowCount, columnCount));

            for (int row = 0; row <= rowCount; row++) // Numeration starts from 0 to MaxDataRow
            {
                for (int column = 0; column <= columnCount; column++)  // Numeration starts from 0 to MaxDataColumn
                {
                    strCell = "";
                    strCell = Convert.ToString(cells[row, column].Value);
                    if (String.IsNullOrEmpty(strCell))
                    {
                        continue;
                    }
                    else
                    {
                        // Do your staff here
                        Console.WriteLine(strCell);
                    }
                }
            }
        }
    }
}

create_function did not work for me inside a class. I had to use call_user_func.

<?php

class Dispatcher {
    //Added explicit callback declaration.
    var $callback;

    public function Dispatcher( $callback ){
         $this->callback = $callback;
    }

    public function asynchronous_method(){
       //do asynch stuff, like fwrite...then, fire callback.
       if ( isset( $this->callback ) ) {
            if (function_exists( $this->callback )) call_user_func( $this->callback, "File done!" );
        }
    }

}

Then, to use:

<?php 
include_once('Dispatcher.php');
$d = new Dispatcher( 'do_callback' );
$d->asynchronous_method();

function do_callback( $data ){
   print 'Data is: ' .  $data .  "\n";
}
?>

[Edit] Added a missing parenthesis. Also, added the callback declaration, I prefer it that way.

Ctrl+Shift+F to invoke the Auto Formatter

Ctrl+I to indent the selected part (or all) of you code.

Of course:

curl http://example.com:11740
curl https://example.com:11740

Port 80 and 443 are just default port numbers.

I had a similar requirement (twitter style text field). Used onkeyup and onchange. onchange actually takes care of mouse paste operations during lost focus from the field.

[Update] In HTML5 or later, use oninput to get real time character modification updates, as explained in other answers above.

Basically, you get connections in the Sleep state when :

• a PHP script connects to MySQL
• some queries are executed
• then, the PHP script does some stuff that takes time
  • without disconnecting from the DB
• and, finally, the PHP script ends
  • which means it disconnects from the MySQL server

So, you generally end up with many processes in a Sleep state when you have a lot of PHP processes that stay connected, without actually doing anything on the database-side.

A basic idea, so : make sure you don't have PHP processes that run for too long -- or force them to disconnect as soon as they don't need to access the database anymore.

Another thing, that I often see when there is some load on the server :

• There are more and more requests coming to Apache
  • which means many pages to generate
• Each PHP script, in order to generate a page, connects to the DB and does some queries
• These queries take more and more time, as the load on the DB server increases
• Which means more processes keep stacking up

A solution that can help is to reduce the time your queries take -- optimizing the longest ones.

Information for obsoleted prerelease software:

According to this it's just a install and go for Visual Studio 2013:

In fact, installing the C# 6.0 compiler from this release involves little more than installing a Visual Studio 2013 extension, which in turn updates the MSBuild target files.

So just get the files from https://github.com/dotnet/roslyn and you are ready to go.

You do have to know it is an outdated version of the specs implemented there, since they no longer update the package for Visual Studio 2013:

You can also try April's End User Preview, which installs on top of Visual Studio 2013. (note: this VS 2013 preview is quite out of date, and is no longer updated)

So if you do want to use the latest version, you have to download the Visual Studio 2015.

isset() is used to check if the variable is set with the value or not and Empty() is used to check if a given variable is empty or not.

isset() returns true when the variable is not null whereas Empty() returns true if the variable is an empty string.

It seems to work, but maybe there is a simpler solution that works in all browsers?

// Create the measurement node_x000D_
var scrollDiv = document.createElement("div");_x000D_
scrollDiv.className = "scrollbar-measure";_x000D_
document.body.appendChild(scrollDiv);_x000D_
_x000D_
// Get the scrollbar width_x000D_
var scrollbarWidth = scrollDiv.offsetWidth - scrollDiv.clientWidth;_x000D_
console.info(scrollbarWidth); // Mac:  15_x000D_
_x000D_
// Delete the DIV _x000D_
document.body.removeChild(scrollDiv);

.scrollbar-measure {_x000D_
 width: 100px;_x000D_
 height: 100px;_x000D_
 overflow: scroll;_x000D_
 position: absolute;_x000D_
 top: -9999px;_x000D_
}

@Kwang-Chun Kang Thanks Kang a lot! I found the solution is working and very helpful, it really save my day. For me I am trying to create a React.js component that convert *.xlsx to json object when user upload the excel file to a html input tag. First I need to install XLSX package with:

npm install xlsx --save

Then in my component code, import with:

import XLSX from 'xlsx'

The component UI should look like this:

<input
  accept=".xlsx"
  type="file"
  onChange={this.fileReader}
/>

It calls a function fileReader(), which is exactly same as the solution provided. To learn more about fileReader API, I found this blog to be helpful: https://blog.teamtreehouse.com/reading-files-using-the-html5-filereader-api

The link has the driver for sqlserver, download and add it your eclipse buildpath.

You have four choices to supply a password:

1. Set the PGPASSWORD environment variable. For details see the manual:
   http://www.postgresql.org/docs/current/static/libpq-envars.html
2. Use a .pgpass file to store the password. For details see the manual:
   http://www.postgresql.org/docs/current/static/libpq-pgpass.html
3. Use "trust authentication" for that specific user: http://www.postgresql.org/docs/current/static/auth-methods.html#AUTH-TRUST
4. Since PostgreSQL 9.1 you can also use a connection string:
   https://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING

You are definitely searching for this

Yii::app()->request->pathInfo

Set registry item for your server instance. For example:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.2\MSSQLServer\BackupDirectory

Not exactly the case of actual context of this question, but this exception can be reproduced by the next query:

update users set dismissal_reason='he can't and don't want' where userid=123

Single quotes in words can't and don't broke the string. In case string have only one inside quote e.g. 'he don't want' oracle throws more relevant quoted string not properly terminated error, but in case of two SQL command not properly ended is thrown.

Summary: check your query for double single quotes.

I found a solution that doesn't need to access directly the pixel data and loop through it to perform the downsampling. Depending on the size of the image this can be very resource intensive, and it would be better to use the browser's internal algorithms.

The drawImage() function is using a linear-interpolation, nearest-neighbor resampling method. That works well when you are not resizing down more than half the original size.

If you loop to only resize max one half at a time, the results would be quite good, and much faster than accessing pixel data.

This function downsample to half at a time until reaching the desired size:

  function resize_image( src, dst, type, quality ) {
     var tmp = new Image(),
         canvas, context, cW, cH;

     type = type || 'image/jpeg';
     quality = quality || 0.92;

     cW = src.naturalWidth;
     cH = src.naturalHeight;

     tmp.src = src.src;
     tmp.onload = function() {

        canvas = document.createElement( 'canvas' );

        cW /= 2;
        cH /= 2;

        if ( cW < src.width ) cW = src.width;
        if ( cH < src.height ) cH = src.height;

        canvas.width = cW;
        canvas.height = cH;
        context = canvas.getContext( '2d' );
        context.drawImage( tmp, 0, 0, cW, cH );

        dst.src = canvas.toDataURL( type, quality );

        if ( cW <= src.width || cH <= src.height )
           return;

        tmp.src = dst.src;
     }

  }
  // The images sent as parameters can be in the DOM or be image objects
  resize_image( $( '#original' )[0], $( '#smaller' )[0] );

If it is in a Docker container, you can just restart your container. Let's assume the container name is jenkins, so you can do:

docker restart jenkins

Or

docker stop jenkins
docker start jenkins

pd.DataFrame.loc can take one or two indexers. For the rest of the post, I'll represent the first indexer as i and the second indexer as j.

If only one indexer is provided, it applies to the index of the dataframe and the missing indexer is assumed to represent all columns. So the following two examples are equivalent.

1. df.loc[i]
2. df.loc[i, :]

Where : is used to represent all columns.

If both indexers are present, i references index values and j references column values.

Now we can focus on what types of values i and j can assume. Let's use the following dataframe df as our example:

    df = pd.DataFrame([[1, 2], [3, 4]], index=['A', 'B'], columns=['X', 'Y'])

loc has been written such that i and j can be

1. scalars that should be values in the respective index objects

   df.loc['A', 'Y']
   
   2
   

2. arrays whose elements are also members of the respective index object (notice that the order of the array I pass to loc is respected

   df.loc[['B', 'A'], 'X']
   
   B    3
   A    1
   Name: X, dtype: int64
   

   • Notice the dimensionality of the return object when passing arrays. i is an array as it was above, loc returns an object in which an index with those values is returned. In this case, because j was a scalar, loc returned a pd.Series object. We could've manipulated this to return a dataframe if we passed an array for i and j, and the array could've have just been a single value'd array.

     df.loc[['B', 'A'], ['X']]
     
        X
     B  3
     A  1
     

3. boolean arrays whose elements are True or False and whose length matches the length of the respective index. In this case, loc simply grabs the rows (or columns) in which the boolean array is True.

   df.loc[[True, False], ['X']]
   
      X
   A  1
   

In addition to what indexers you can pass to loc, it also enables you to make assignments. Now we can break down the line of code you provided.

iris_data.loc[iris_data['class'] == 'versicolor', 'class'] = 'Iris-versicolor'

1. iris_data['class'] == 'versicolor' returns a boolean array.
2. class is a scalar that represents a value in the columns object.
3. iris_data.loc[iris_data['class'] == 'versicolor', 'class'] returns a pd.Series object consisting of the 'class' column for all rows where 'class' is 'versicolor'

4. When used with an assignment operator:

   iris_data.loc[iris_data['class'] == 'versicolor', 'class'] = 'Iris-versicolor'
   

   We assign 'Iris-versicolor' for all elements in column 'class' where 'class' was 'versicolor'

It is not entirely clear what you want, but I would use numpy.random.randint:

import numpy.random as nprnd
import timeit

t1 = timeit.Timer('[random.randint(0, 1000) for r in xrange(10000)]', 'import random') # v1

### Change v2 so that it picks numbers in (0, 10000) and thus runs...
t2 = timeit.Timer('random.sample(range(10000), 10000)', 'import random') # v2
t3 = timeit.Timer('nprnd.randint(1000, size=10000)', 'import numpy.random as nprnd') # v3

print t1.timeit(1000)/1000
print t2.timeit(1000)/1000
print t3.timeit(1000)/1000

which gives on my machine:

0.0233682730198
0.00781716918945
0.000147947072983

Note that randint is very different from random.sample (in order for it to work in your case I had to change the 1,000 to 10,000 as one of the commentators pointed out -- if you really want them from 0 to 1,000 you could divide by 10).

And if you really don't care what distribution you are getting then it is possible that you either don't understand your problem very well, or random numbers -- with apologies if that sounds rude...

Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)

In my Case I used it in a lot of places first example if you have 2 values for select statement like gender (Male or Female) then use the following statement:

SELECT CASE Gender WHEN 'Male' THEN 1 ELSE 2 END AS Gender

If there is more than one condition like nationalities you can use it as the following statement:

SELECT CASE Nationality 
WHEN 'AMERICAN'   THEN 1 
WHEN 'BRITISH'   THEN 2
WHEN 'GERMAN'    THEN 3 
WHEN 'EGYPT'     THEN 4 
WHEN 'PALESTINE' THEN 5 
ELSE 6 END AS Nationality 

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

It looks like you can download just the grid now on Bootstrap 4s new download features.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

In latest IntelliJ versions, you should run it from Analyze->Run Inspection By Name:

Than, pick Unused declaration:

And finally, uncheck the Include test sources:

protected void doPost(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {

    boolean isMultipart = ServletFileUpload.isMultipartContent(request);

    if (!isMultipart) {
        return;
    }

    DiskFileItemFactory factory = new DiskFileItemFactory();

    factory.setSizeThreshold(MAX_MEMORY_SIZE);

    factory.setRepository(new File(System.getProperty("java.io.tmpdir")));

    String uploadFolder = getServletContext().getRealPath("")
            + File.separator + DATA_DIRECTORY;//DATA_DIRECTORY is directory where you upload this file on the server

    ServletFileUpload upload = new ServletFileUpload(factory);

    upload.setSizeMax(MAX_REQUEST_SIZE);//MAX_REQUEST_SIZE is the size which size you prefer

And use <form enctype="multipart/form-data"> and use <input type="file"> in the html

The <a>nchor element is simply an anchor to or from some content. Originally the HTML specification allowed for named anchors (<a name="foo">) and linked anchors (<a href="#foo">).

The named anchor format is less commonly used, as the fragment identifier is now used to specify an [id] attribute (although for backwards compatibility you can still specify [name] attributes). An <a> element without an [href] attribute is still valid.

As far as semantics and styling is concerned, the <a> element isn't a link (:link) unless it has an [href] attribute. A side-effect of this is that an <a> element without [href] won't be in the tabbing order by default.

The real question is whether the <a> element alone is an appropriate representation of a <button>. On a semantic level, there is a distinct difference between a link and a button.

A button is something that when clicked causes an action to occur.

A link is a button that causes a change in navigation in the current document. The navigation that occurs could be moving within the document in the case of fragment identifiers (#foo) or moving to a new document in the case of urls (/bar).

As links are a special type of button, they have often had their actions overridden to perform alternative functions. Continuing to use an anchor as a button is ok from a consistency standpoint, although it's not quite accurate semantically.

If you're concerned about the semantics and accessibility of using an <a> element (or <span>, or <div>) as a button, you should add the following attributes:

<a role="button" tabindex="0" ...>...</a>

The button role tells the user that the particular element is being treated as a button as an override for whatever semantics the underlying element may have had.

For <span> and <div> elements, you may want to add JavaScript key listeners for Space or Enter to trigger the click event. <a href> and <button> elements do this by default, but non-button elements do not. Sometimes it makes more sense to bind the click trigger to a different key. For example, a "help" button in a web app might be bound to F1.

for followers, this error message can also mean "you have it referencing a foreign object that hasn't been saved to the DB yet" (even though it's there, and is non null).

mystycs, you are using the variable i to control your loop, however you are editing the value of i within the loop:

for (int i=0; i < positiveInteger; i++)
{
    i = startingNumber + 1;
    cout << i;
}

Try this instead:

int sum = 0;

for (int i=0; i < positiveInteger; i++)
{
    sum = sum + i;
    cout << sum << " " << i;
}

Disable Power Save Mode and Invalidate Cache and Restart.

You can use it with your local variables, like this:

@animal = "Dog"
@action = "licks"
@second_animal = "Bird"

"The #{@animal} #{@action} the #{@second_animal}"

the output would be: "The Dog licks the Bird"

You can do it in one line:

ls /home/edward/bank1/fiche/Test* >/dev/null 2>&1 && echo "found one" || echo "found none"

To understand what it does you have to decompose the command and have a basic awareness of boolean logic.

Directly from bash man page:

[...]
expression1 && expression2
     True if both expression1 and expression2 are true.
expression1 || expression2
     True if either expression1 or expression2 is true.
[...]

In the shell (and in general in unix world), the boolean true is a program that exits with status 0.

ls tries to list the pattern, if it succeed (meaning the pattern exists) it exits with status 0, 2 otherwise (have a look at ls man page for details).

In our case there are actually 3 expressions, for the sake of clarity I will put parenthesis, although they are not needed because && has precedence on ||:

 (expression1 && expression2) || expression3

so if expression1 is true (ie: ls found the pattern) it evaluates expression2 (which is just an echo and will exit with status 0). In this case expression3 is never evaluate because what's on the left site of || is already true and it would be a waste of resources trying to evaluate what's on the right.

Otherwise, if expression1 is false, expression2 is not evaluated but in this case expression3 is.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

Right after @mail($email_to, $email_subject, $email_message, $headers);

header('Location: nextpage.php');

Note that you will never see 'Thanks for subscribing to our mailing list'

That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!

I suggest to see the classic example at: http://maven.apache.org/guides/getting-started/index.html#How_do_I_build_more_than_one_project_at_once

Here my-webapp is web project, which depends on the code at my-app project. So to bundle two projects in one, we have top level pom.xml which mentions which are the projects (modules as per maven terminology) to be bundled finally. Such top level pom.xml can use pom packaging.

my-webapp can have war packaging and can have dependency on my-app. my-app can have jar packaging.

Since you are using enumerate hence your i is actually the index of the key rather than the key itself.

So, you are getting 3 in the first column of the row 3 4even though there is no key 3.

enumerate iterates through a data structure(be it list or a dictionary) while also providing the current iteration number.

Hence, the columns here are the iteration number followed by the key in dictionary enum

Others Solutions have already shown how to iterate over key and value pair so I won't repeat the same in mine.

To find out what ports rabbitmq uses:

$ epmd -names

Outputs:

epmd: up and running on port 4369 with data:
name rabbit at port 25672

Run these as root:

lsof -i :4369
lsof -i :25672

More about epmd options.

On my end, I used Resource Monitor to see which application was still listening to port 5037 after all the Eclipse and adb restart were unsuccessful for me.

Start > All Programs > Accessories > System Tools >
Resource Monitor > Network > Listening Ports

This eventually showed that java.exe was listening to port 5037, hence, preventing adb from doing so. I killed java.exe, immediately start adb (with adb start-server) and received a confirmation that adb was able to start:

android-sdks\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

I know you wanted only a hypertext link, but if you copy & paste a link address into Slack that does work very nicely. i.e. if referring to VersionOne ticket number (V1 mouseover the ticket window to open the mouseover window, then right click on the ticket number for the option to "copy link address", then in Slack paste. It'll paste the full ticket URL but then it shows a nice summary of the ticket number and name and you can click it to go right into the ticket.)

You are getting the error because $ret is not an array.

To get rid of the error, at the start of your function, define it with this line: $ret = array();

It appears that the get_tags() call is returning nothing, so the foreach is not run, which means that $ret isn't defined.

Try wrapping your dates in single quotes, like this:

'15-6-2005'

It should be able to parse the date this way.

In Java, when you type a decimal number as 3.6, its interpreted as a double. double is a 64-bit precision IEEE 754 floating point, while floatis a 32-bit precision IEEE 754 floating point. As a float is less precise than a double, the conversion cannot be performed implicitly.

If you want to create a float, you should end your number with f (i.e.: 3.6f).

For more explanation, see the primitive data types definition of the Java tutorial.

If you want a "editable grid" i.e. a table like structure that allows you to make any of the rows a form, use CSS that mimics the TABLE tag's layout: display:table, display:table-row, and display:table-cell.

There is no need to wrap your whole table in a form and no need to create a separate form and table for each apparent row of your table.

Try this instead:

<style>
DIV.table 
{
    display:table;
}
FORM.tr, DIV.tr
{
    display:table-row;
}
SPAN.td
{
    display:table-cell;
}
</style>

<div class="table">
    <form class="tr" method="post" action="blah.html">

The problem with wrapping the whole TABLE in a FORM is that any and all form elements will be sent on submit (maybe that is desired but probably not). This method allows you to define a form for each "row" and send only that row of data on submit.

The problem with wrapping a FORM tag around a TR tag (or TR around a FORM) is that it's invalid HTML. The FORM will still allow submit as usual but at this point the DOM is broken. Note: Try getting the child elements of your FORM or TR with JavaScript, it can lead to unexpected results.

Note that IE7 doesn't support these CSS table styles and IE8 will need a doctype declaration to get it into "standards" mode: (try this one or something equivalent)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Any other browser that supports display:table, display:table-row and display:table-cell should display your css data table the same as it would if you were using the TABLE, TR and TD tags. Most of them do.

Note that you can also mimic THEAD, TBODY, TFOOT by wrapping your row groups in another DIV with display: table-header-group, table-row-group and table-footer-group respectively.

NOTE: The only thing you cannot do with this method is colspan.

I found an easy way, which has a few restrictions, but worked for me:

• define the shape in defs
• define a clip path referencing the shape
• use it and double the stroke with as the outside is clipped

Here a working example:

<svg width="240" height="240" viewBox="0 0 1024 1024">_x000D_
<defs>_x000D_
 <path id="ld" d="M256,0 L0,512 L384,512 L128,1024 L1024,384 L640,384 L896,0 L256,0 Z"/>_x000D_
 <clipPath id="clip">_x000D_
  <use xlink:href="#ld"/>_x000D_
 </clipPath>_x000D_
</defs>_x000D_
<g>_x000D_
 <use xlink:href="#ld" stroke="#0081C6" stroke-width="160" fill="#00D2B8" clip-path="url(#clip)"/>_x000D_
</g>_x000D_
</svg>

checkbox that act like radio btn

$(".checkgroup").live('change',function() { var previous=this.checked; $(".checkgroup).attr("checked", false); $(this).attr("checked", previous); });

In xml edittext:

android:id="@+id/text"

In program:

EditText text=(EditText) findViewById(R.id.text);
text.setRawInputType(Configuration.KEYBOARDHIDDEN_YES);

Also got the same error when using ajax.

If you're using ajax to render forms with select2, the input_html class must be different from those NOT rendered using ajax. Not quite sure why it works this way though.

Convert PPK to OpenSSh

OS X: Install Homebrew, then run

brew install putty

Place your keys in some directory, e.g. your home folder. Now convert the PPK keys to SSH keypairs:cache search

To generate the private key:

cd ~

puttygen id_dsa.ppk -O private-openssh -o id_dsa

and to generate the public key:

puttygen id_dsa.ppk -O public-openssh -o id_dsa.pub

Move these keys to ~/.ssh and make sure the permissions are set to private for your private key:

mkdir -p ~/.ssh
mv -i ~/id_dsa* ~/.ssh
chmod 600 ~/.ssh/id_dsa
chmod 666 ~/.ssh/id_dsa.pub

connect with ssh server

ssh -i ~/.ssh/id_dsa username@servername

Port Forwarding to connect mysql remote server

ssh -i ~/.ssh/id_dsa -L 9001:127.0.0.1:3306 username@serverName

The best method I know of is to use a Perceptual Hash. There appears to be a good open source implementation of such a hash available at:

http://phash.org/

The main idea is that each image is reduced down to a small hash code or 'fingerprint' by identifying salient features in the original image file and hashing a compact representation of those features (rather than hashing the image data directly). This means that the false positives rate is much reduced over a simplistic approach such as reducing images down to a tiny thumbprint sized image and comparing thumbprints.

phash offers several types of hash and can be used for images, audio or video.

Merge squash merges a tree (a sequence of commits) into a single commit. That is, it squashes all changes made in n commits into a single commit.

Rebasing is re-basing, that is, choosing a new base (parent commit) for a tree. Maybe the mercurial term for this is more clear: they call it transplant because it's just that: picking a new ground (parent commit, root) for a tree.

When doing an interactive rebase, you're given the option to either squash, pick, edit or skip the commits you are going to rebase.

Hope that was clear!

import yaml

data = dict(
    A = 'a',
    B = dict(
        C = 'c',
        D = 'd',
        E = 'e',
    )
)

with open('data.yml', 'w') as outfile:
    yaml.dump(data, outfile, default_flow_style=False)

The default_flow_style=False parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:

A: a
B: {C: c, D: d, E: e}

Remove it using Craco:

module.exports = {
  webpack: {
    configure: webpackConfig => {
      const scopePluginIndex = webpackConfig.resolve.plugins.findIndex(
        ({ constructor }) => constructor && constructor.name === 'ModuleScopePlugin'
      );

      webpackConfig.resolve.plugins.splice(scopePluginIndex, 1);
      return webpackConfig;
    }
  }
};

1. Create a file in drawable play_pause.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true"
          android:drawable="@drawable/pause" />

    <item android:state_selected="false"
          android:drawable="@drawable/play" />
    <!-- default -->
</selector>

2. In xml file add this below code

 <ImageView
                android:id="@+id/iv_play"
                android:layout_width="@dimen/_50sdp"
                android:layout_height="@dimen/_50sdp"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:background="@drawable/pause_button"
                android:gravity="center"
                android:scaleType="fitXY" />

3. In java file add this below code

iv_play = (ImageView) findViewById(R.id.iv_play);
iv_play.setSelected(false);

and also add this

iv_play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                iv_play.setSelected(!iv_play.isSelected());
                if (iv_play.isSelected()) {
                    ((GifDrawable) gif_1.getDrawable()).start();
                    ((GifDrawable) gif_2.getDrawable()).start();
                } else {
                    iv_play.setSelected(false);
                    ((GifDrawable) gif_1.getDrawable()).stop();
                    ((GifDrawable) gif_2.getDrawable()).stop();
                }
            }
        });

Use Python to list groupmembers:

python -c "import grp; print grp.getgrnam('GROUP_NAME')[3]"

See https://docs.python.org/2/library/grp.html

history.go(-1) this is a possible solution to the problem but it does not work in incognito mode as history is not maintained by the browser in this mode.

If you are developing a command line interface, I suggest you to take a look at click which is very nice:

import click
import time

for filename in range(3):
    with click.progressbar(range(100), fill_char='=', empty_char=' ') as bar:
        for user in bar:
            time.sleep(0.01)

Here the output you get:

$ python test.py
  [====================================]  100%
  [====================================]  100%
  [=========                           ]   27%

Disabling tracking will also cause your result sets to be streamed into memory. This is more efficient when you're working with large sets of data and don't need the entire set of data all at once.

I use the following to detect different mobile devices, viewport and screen. Works quite well for me, might be helpful to others:

var pixelRatio = window.devicePixelRatio || 1;

var viewport = {
    width: window.innerWidth,
    height: window.innerHeight
};

var screen = {
    width: window.screen.availWidth * pixelRatio,
    height: window.screen.availHeight * pixelRatio
};

var iPhone = /iPhone/i.test(navigator.userAgent);
var iPhone4 = (iPhone && pixelRatio == 2);
var iPhone5 = /iPhone OS 5_0/i.test(navigator.userAgent);
var iPad = /iPad/i.test(navigator.userAgent);
var android = /android/i.test(navigator.userAgent);
var webos = /hpwos/i.test(navigator.userAgent);
var iOS = iPhone || iPad;
var mobile = iOS || android || webos;

window.devicePixelRatio is the ratio between physical pixels and device-independent pixels (dips) on the device. window.devicePixelRatio = physical pixels / dips.

Each modal should be given a different id and each link should be targeted to a different modal id. So it should be something like that:

<a href="#myModal" data-toggle="modal">
...
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>
...
<a href="#myModal2" data-toggle="modal">
...
<div id="myModal2" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>
...

If the file was added with your most recent commit, and you have not pushed to the remote repository, you can delete the file and amend the commit, Taken from here:

git rm --cached giant_file
    # Stage "giant_file" for removal with "git rm"
    # Leave it on disk with "--cached". if you want to remove it from disk
    # then ignore the "--cached" parameter
git commit --amend -CHEAD
    # Commit the current tree without the giant file using "git commit"
    # Amend the previous commit with your change "--amend" 
    # (simply making a new commit won't work, as you need
    # to remove the file from the unpushed history as well)
    # Use the log/authorship/timestamp of the last commit (the one we are
    # amending) with "-CHEAD", equivalent to --reuse-message=HEAD
git push
    # Push our rewritten, smaller commit with "git push"

You can pass $state to your controller and then when the page loads and calls the getter in the controller you call $state.go('index') or whatever partial you want to load. Done.

Change

<serviceMetadata httpsGetEnabled="true"/>

to

<serviceMetadata httpsGetEnabled="false"/>

You're telling WCF to use https for the metadata endpoint and I see that your'e exposing your service on http, and then you get the error in the title.

You also have to set <security mode="None" /> if you want to use HTTP as your URL suggests.

inside your onClickListener.onClick, put

getFragmentManager().beginTransaction().replace(R.id.container, new tasks()).commit();

In another word, in your mycontacts.class

public class mycontacts extends Fragment {

    public mycontacts() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View v = super.getView(position, convertView, parent);
        ImageView purple = (ImageView) v.findViewById(R.id.imageView1);
        purple.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                getFragmentManager()
                        .beginTransaction()
                        .replace(R.id.container, new tasks())
                        .commit();
            }
        });
        return view;

    }
}

now, remember R.id.container is the container (FrameLayout or other layouts) for the activity that calls the fragment

std::fill(v.begin(), v.end(), 0);

I got the same issue while running the skiprows while reading the csv file. I was doning skip_rows=1 this will not work

Simple example gives an idea how to use skiprows while reading csv file.

import pandas as pd

#skiprows=1 will skip first line and try to read from second line
df = pd.read_csv('my_csv_file.csv', skiprows=1)  ## pandas as pd

#print the data frame
df

from django.contrib.sites.models import Site
if Site._meta.installed:
    site = Site.objects.get_current()
else:
    site = RequestSite(request)

You're trying to access a JSON, not JSONP.

Notice the difference between your source:

https://api.flightstats.com/flex/schedules/rest/v1/json/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59&callback=?

And actual JSONP (a wrapping function):

http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=processJSON&tags=monkey&tagmode=any&format=json

Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.

Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class

  myObj:any = {
    doSomething: function () { console.log('doing something'); return 'doing something'; },
  };
  myArray:any;
  constructor() { }

  ngOnInit() {
    this.myArray = [this.myObj];
  }

You can use it in template html file as following:

<div>test-1: {{  myObj?.doSomething()}}</div>
<div>test-2: {{  myArray[0].doSomething()}}</div>
<div>test-3: {{  myArray[2]?.doSomething()}}</div>

My preference is to encode all non-alphaumeric characters as HTML numeric character entities. Since almost, if not all attacks require non-alphuneric characters (like <, ", etc) this should eliminate a large chunk of dangerous output.

Format is &#N;, where N is the numeric value of the character (you can just cast the character to an int and concatenate with a string to get a decimal value). For example:

// java-ish pseudocode
StringBuffer safestrbuf = new StringBuffer(string.length()*4);
foreach(char c : string.split() ){  
  if( Character.isAlphaNumeric(c) ) safestrbuf.append(c);
  else safestrbuf.append(""+(int)symbol);

You will also need to be sure that you are encoding immediately before outputting to the browser, to avoid double-encoding, or encoding for HTML but sending to a different location.

I won't talk much. Already my respected fellow friends have given their valuable input. The full fledged running code at the last of this blog should remove any confusion. It's about a movie seat booking small program in multi-threaded scenario.

Some important elementary facts are as follows. 1> Different threads can only contend for instance and static member variables in the heap space. 2> Volatile read or write are completely atomic and serialized/happens before and only done from memory. By saying this I mean that any read will follow the previous write in memory. And any write will follow the previous read from memory. So any thread working with a volatile will always see the most up-to-date value. AtomicReference uses this property of volatile.

Following are some of the source code of AtomicReference. AtomicReference refers to an object reference. This reference is a volatile member variable in the AtomicReference instance as below.

private volatile V value;

get() simply returns the latest value of the variable (as volatiles do in a "happens before" manner).

public final V get()

Following is the most important method of AtomicReference.

public final boolean  compareAndSet(V expect, V update) {
        return unsafe.compareAndSwapObject(this, valueOffset, expect, update);
}

The compareAndSet(expect,update) method calls the compareAndSwapObject() method of the unsafe class of Java. This method call of unsafe invokes the native call, which invokes a single instruction to the processor. "expect" and "update" each reference an object.

If and only if the AtomicReference instance member variable "value" refers to the same object is referred to by "expect", "update" is assigned to this instance variable now, and "true" is returned. Or else, false is returned. The whole thing is done atomically. No other thread can intercept in between. As this is a single processor operation (magic of modern computer architecture), it's often faster than using a synchronized block. But remember that when multiple variables need to be updated atomically, AtomicReference won't help.

I would like to add a full fledged running code, which can be run in eclipse. It would clear many confusion. Here 22 users (MyTh threads) are trying to book 20 seats. Following is the code snippet followed by the full code.

Code snippet where 22 users are trying to book 20 seats.

for (int i = 0; i < 20; i++) {// 20 seats
            seats.add(new AtomicReference<Integer>());
        }
        Thread[] ths = new Thread[22];// 22 users
        for (int i = 0; i < ths.length; i++) {
            ths[i] = new MyTh(seats, i);

As others suggested, you can use String.compareTo(String).

But if you are sorting a list of Strings and you need a Comparator, you don't have to implement it, you can use Comparator.naturalOrder() or Comparator.reverseOrder().

You can access Gist by visiting the following url gist.github.com. Alternatively you can access it from within your Github account (after logging in) as shown in the picture below:

Github: A hosting service that houses a web-based git repository. It includes all the fucntionality of git with additional features added in.

Gist: Is an additional feature added to github to allow the sharing of code snippets, notes, to do lists and more. You can save your Gists as secret or public. Secret Gists are hidden from search engines but visible to anyone you share the url with.

For example. If you wanted to write a private to-do list. You could write one using Github Markdown as follows:

NB: It is important to preserve the whitespace as shown above between the dash and brackets. It is also important that you save the file with the extension .md because we want the markdown to format properly. Remember to save this Gist as secret if you do not want others to see it.

The end result looks like the image below. The checkboxes are clickable because we saved this Gist with the extension .md
