Okay,I have re-installed the package via pip even that didn't help. And then I rsync'ed the entire /usr/lib/python-2.7 directory from other working machine with similar configuration to the current machine.It started working. I don't have any idea ,what was wrong with my setup. I see some difference "print sys.path" output earlier and now. but now my issue is resolved by this work around.

EDIT:Found the real solution for my setup. upgrading "sqlalchemy only doesn't solve the issue" I also need to upgrade flask-sqlalchemy that resolved the issue.

To check that the file you're trying to open actually exists, you can change directories in terminal using cd. To change to ~/Desktop/sass/css: cd ~/Desktop/sass/css. To see what files are in the directory: ls.

If you want information about either of those commands, use the man page: man cd or man ls, for example.

Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.

On Mac OS X, you can also use open to open a finder window: open . will open the current directory in finder. (open ~/Desktop/sass/css will open the ~/Desktop/sass/css).

json_str = String.raw`[{"name": "Jeeva"}, {"name": "Kumar"}]`;_x000D_
obj = JSON.parse(json_str);_x000D_
_x000D_
console.log(obj[0]["name"]);

I did this for my cordova app, like I created a new javascript file for the JSON and pasted the JSON data into String.raw then parse it with JSON.parse

you can try like this without using jquery

window.addEventListener("load", afterLoaded,false);
function afterLoaded(){
alert("after load")
}

Let's say you additionally want the week to begin on Monday (instead of default on Sunday), then the following is helpful:

require(lubridate)
df$day = ifelse(wday(df$time)==1,6,wday(df$time)-2)

The result is the days in the interval [0,..,6].

If you want the interval to be [1,..7], use the following:

df$day = ifelse(wday(df$time)==1,7,wday(df$time)-1)

... or, alternatively:

df$day = df$day + 1

This helped me to get rid of this error.This option disables -XX:+DisableExplicitGC

Close/dispose your WebResponse object.

From my experience in React Native, you can also restart your CLI and this error goes away.

Another way num1 = (20*boolVar)+(num1*(not boolVar))

WebView.loadData() is not working properly at all. What I had to do was:

String header = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>";
myWebView.loadData(header+myHtmlString, "text/html", "UTF-8");

I think in your case you should replace UTF-8 with latin1 or ISO-8859-1 both in header and in WebView.loadData().

And, to give a full answer, here is the official list of encodings: http://www.iana.org/assignments/character-sets

I update my answer to be more inclusive:

To use WebView.loadData() with non latin1 encodings you have to encode html content. Previous example was not correctly working in Android 4+, so I have modified it to look as follows:

WebSettings settings = myWebView.getSettings();
settings.setDefaultTextEncodingName("utf-8");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.FROYO) {
    String base64 = Base64.encodeToString(htmlString.getBytes(), Base64.DEFAULT);
    myWebView.loadData(base64, "text/html; charset=utf-8", "base64");
} else {
    String header = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>";
    myWebView.loadData(header + htmlString, "text/html; charset=UTF-8", null);

}

But later I have switched to WebView.loadDataWithBaseURL() and the code became very clean and not depending on Android version:

WebSettings settings = myWebView.getSettings();
settings.setDefaultTextEncodingName("utf-8");
myWebView.loadDataWithBaseURL(null, htmlString, "text/html", "utf-8", null);

For some reason these functions have completely different implementation.

Instead of this

df = df[(99 <= df['closing_price'] <= 101)]

You should use this

df = df[(df['closing_price']>=99 ) & (df['closing_price']<=101)]

We have to use NumPy's bitwise Logic operators |, &, ~, ^ for compounding queries. Also, the parentheses are important for operator precedence.

I have a directory with 88,914 files in it. Like yourself this is used for storing thumbnails and on a Linux server.

Listed files via FTP or a php function is slow yes, but there is also a performance hit on displaying the file. e.g. www.website.com/thumbdir/gh3hg4h2b4h234b3h2.jpg has a wait time of 200-400 ms. As a comparison on another site I have with a around 100 files in a directory the image is displayed after just ~40ms of waiting.

I've given this answer as most people have just written how directory search functions will perform, which you won't be using on a thumb folder - just statically displaying files, but will be interested in performance of how the files can actually be used.

Well, by IP is faster.

Basically, when you call by server name, it is converted to original IP.

But it would be difficult to memorize an IP, for this reason the domain name was created.

Personally I use http://localhost instead of http://127.0.0.1 or http://username.

Right click on the table in SQL Management Studio.

Select Script... Create to... New Query Window.

This will generate a script to recreate the table in a new query window.

Change the name of the table in the script to whatever you want the new table to be named.

Execute the script.

Character.isDigit(string.charAt(0))

Note that this will allow any Unicode digit, not just 0-9. You might prefer:

char c = string.charAt(0);
isDigit = (c >= '0' && c <= '9');

Or the slower regex solutions:

s.substring(0, 1).matches("\\d")
// or the equivalent
s.substring(0, 1).matches("[0-9]")

However, with any of these methods, you must first be sure that the string isn't empty. If it is, charAt(0) and substring(0, 1) will throw a StringIndexOutOfBoundsException. startsWith does not have this problem.

To make the entire condition one line and avoid length checks, you can alter the regexes to the following:

s.matches("\\d.*")
// or the equivalent
s.matches("[0-9].*")

If the condition does not appear in a tight loop in your program, the small performance hit for using regular expressions is not likely to be noticeable.

Please, see oficial encode() and decode() documentation from codecs library. utf-8 is the default encoding for the functions, but there are severals standard encodings in Python 3, like latin_1 or utf_32.

This is because of the proxy settings. I also had the same problem, under which I could not use any of the modules which were fetching data from the internet. There are simple steps to follow:
1. open the control panel
2. open internet options
3. under connection tab open LAN settings
4. go to advance settings and unmark everything, delete every proxy in there. Or u can just unmark the checkbox in proxy server this will also do the same
5. save all the settings by clicking ok.
you are done. try to run the programme again, it must work it worked for me at least

Generally, I use null for values that I know can have a "null" state; for example

if(jane.isManager == false){
  jane.employees = null
}

Otherwise, if its a variable or function that's not defined yet (and thus, is not "usable" at the moment) but is supposed to be setup later, I usually leave it undefined.

You can create an array dynamically in this way:

 static void Main()
    {
        // Create a string array 2 elements in length:
        int arrayLength = 2;
        Array dynamicArray = Array.CreateInstance(typeof(int), arrayLength);
        dynamicArray.SetValue(234, 0);                              //  ? a[0] = 234;
        dynamicArray.SetValue(444, 1);                              //  ? a[1] = 444;
        int number = (int)dynamicArray.GetValue(0);                      //  ? number = a[0];


        int[] cSharpArray = (int[])dynamicArray;
        int s2 = cSharpArray[0];

    }

It's a warning, not an error. It occurs because fsevents is an optional dependency, used only when project is run on macOS environment (the package provides 'Native Access to Mac OS-X FSEvents').

And since you're running your project on Windows, fsevents is skipped as irrelevant.

There is a PR to fix this behaviour here: https://github.com/npm/cli/pull/169

They aren't really concepts but rather specific keywords that tend to occur (with slightly different semantics) in popular languages like C++ and Java.

Essentially, they are meant to allow a class to restrict access to members (fields or functions). The idea is that the less one type is allowed to access in another type, the less dependency can be created. This allows the accessed object to be changed more easily without affecting objects that refer to it.

Broadly speaking, public means everyone is allowed to access, private means that only members of the same class are allowed to access, and protected means that members of subclasses are also allowed. However, each language adds its own things to this. For example, C++ allows you to inherit non-publicly. In Java, there is also a default (package) access level, and there are rules about internal classes, etc.

Laravel min and max validation do not work properly with a numeric rule validation. Instead of numeric, min and max, Laravel provided a rule digits_between.

$this->validate($request,[
        'field_name'=>'digits_between:2,5',
       ]);

Is there a reason why you can't use the Excel ODBC connection to read and write to Excel? For example, I've used the following code to read from an Excel file row by row like a database:

private DataTable LoadExcelData(string fileName)
{
  string Connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=1\";";

  OleDbConnection con = new OleDbConnection(Connection);

  OleDbCommand command = new OleDbCommand();

  DataTable dt = new DataTable(); OleDbDataAdapter myCommand = new OleDbDataAdapter("select * from [Sheet1$] WHERE LastName <> '' ORDER BY LastName, FirstName", con);

  myCommand.Fill(dt);

  Console.WriteLine(dt.Rows.Count);

  return dt;
}

You can write to the Excel "database" the same way. As you can see, you can select the version number to use so that you can downgrade Excel versions for the machine with Excel 2003. Actually, the same is true for using the Interop. You can use the lower version and it should work with Excel 2003 even though you only have the higher version on your development PC.

extension UIColor {
    convenience init(hexaString: String, alpha: CGFloat = 1) {
        let chars = Array(hexaString.dropFirst())
        self.init(red:   .init(strtoul(String(chars[0...1]),nil,16))/255,
                  green: .init(strtoul(String(chars[2...3]),nil,16))/255,
                  blue:  .init(strtoul(String(chars[4...5]),nil,16))/255,
                  alpha: alpha)}
}

Usage:

let redColor       = UIColor(hexaString: "#FF0000")              // r 1,0 g 0,0 b 0,0 a 1,0
let transparentRed = UIColor(hexaString: "#FF0000", alpha: 0.5)  // r 1,0 g 0,0 b 0,0 a 0,5

I sugges to use the Apache Commons CSV https://commons.apache.org/proper/commons-csv/

Here is one example:

    Path currentRelativePath = Paths.get("");
    String currentPath = currentRelativePath.toAbsolutePath().toString();
    String csvFile = currentPath + "/pathInYourProject/test.csv";

    Reader in;
    Iterable<CSVRecord> records = null;
    try
    {
        in = new FileReader(csvFile);
        records = CSVFormat.EXCEL.withHeader().parse(in); // header will be ignored
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }

    for (CSVRecord record : records) {
        String line = "";
        for ( int i=0; i < record.size(); i++)
        {
            if ( line == "" )
                line = line.concat(record.get(i));
            else
                line = line.concat("," + record.get(i));
        }
        System.out.println("read line: " + line);
    }

It automaticly recognize , and " but not ; (maybe it can be configured...).

My example file is:

col1,col2,col3
val1,"val2",val3
"val4",val5
val6;val7;"val8"

And output is:

read line: val1,val2,val3
read line: val4,val5
read line: val6;val7;"val8"

Last line is considered like one value.

Put the identity element before the authentication element

try this

the solution is, work with callbacks like this

$(function() {

    var jForm = $('form[name=form]');
    var jPWField = $('#employee_password');

    function getCheckedState() {
        return jForm.data('checked_state');
    };

    function setChecked(s) {
        jForm.data('checked_state', s);
    };


    jPWField.change(function() {
        //reset checked thing
        setChecked(null);
    }).trigger('change');

    jForm.submit(function(){
        switch(getCheckedState()) {
            case 'valid':
                return true;
            case 'invalid':
                //invalid, don submit
                return false;
            default:
                //make your check
                var password = $.trim(jPWField.val());

                $.ajax({
                    type: "POST",
                    async: "false",
                    url: "checkpass.php",
                    data: {
                        "password": $.trim(jPWField.val);
                    }
                    success: function(html) {
                        var arr=$.parseJSON(html);
                        setChecked(arr == "Successful" ? 'valid': 'invalid');
                        //submit again
                        jForm.submit();
                    }
                    });
                return false;
        }

    });
 });

Since Python 3.6 there is a method choices from the random module.

Python 3.6.1 (v3.6.1:69c0db5050, Mar 21 2017, 01:21:04)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.0.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import random

In [2]: random.choices(
...:     population=[['a','b'], ['b','a'], ['c','b']],
...:     weights=[0.2, 0.2, 0.6],
...:     k=10
...: )

Out[2]:
[['c', 'b'],
 ['c', 'b'],
 ['b', 'a'],
 ['c', 'b'],
 ['c', 'b'],
 ['b', 'a'],
 ['c', 'b'],
 ['b', 'a'],
 ['c', 'b'],
 ['c', 'b']]

Note that random.choices will sample with replacement, per the docs:

Return a k sized list of elements chosen from the population with replacement.

Note for completeness of answer:

When a sampling unit is drawn from a finite population and is returned to that population, after its characteristic(s) have been recorded, before the next unit is drawn, the sampling is said to be "with replacement". It basically means each element may be chosen more than once.

If you need to sample without replacement, then as @ronan-paixão's brilliant answer states, you can use numpy.choice, whose replace argument controls such behaviour.

I've written an article that explains how to extend the Distinct function so that you can do as follows:

var people = new List<Person>();

people.Add(new Person(1, "a", "b"));
people.Add(new Person(2, "c", "d"));
people.Add(new Person(1, "a", "b"));

foreach (var person in people.Distinct(p => p.ID))
    // Do stuff with unique list here.

Here's the article (now in the Web Archive): Extending LINQ - Specifying a Property in the Distinct Function

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

Difference between a Spy and a Mock

When Mockito creates a mock – it does so from the Class of a Type, not from an actual instance. The mock simply creates a bare-bones shell instance of the Class, entirely instrumented to track interactions with it. On the other hand, the spy will wrap an existing instance. It will still behave in the same way as the normal instance – the only difference is that it will also be instrumented to track all the interactions with it.

In the following example – we create a mock of the ArrayList class:

@Test
public void whenCreateMock_thenCreated() {
    List mockedList = Mockito.mock(ArrayList.class);

    mockedList.add("one");
    Mockito.verify(mockedList).add("one");

    assertEquals(0, mockedList.size());
}

As you can see – adding an element into the mocked list doesn’t actually add anything – it just calls the method with no other side-effect. A spy on the other hand will behave differently – it will actually call the real implementation of the add method and add the element to the underlying list:

@Test
public void whenCreateSpy_thenCreate() {
    List spyList = Mockito.spy(new ArrayList());
    spyList.add("one");
    Mockito.verify(spyList).add("one");

    assertEquals(1, spyList.size());
}

Here we can surely say that the real internal method of the object was called because when you call the size() method you get the size as 1, but this size() method isn’t been mocked! So where does 1 come from? The internal real size() method is called as size() isn’t mocked (or stubbed) and hence we can say that the entry was added to the real object.

to expand a bit on Ricardo's answer: https://stackoverflow.com/a/11873775/7672426

http://api.jquery.com/val/#val2

about val()

Setting values using this method (or using the native value property) does not cause the dispatch of the change event. For this reason, the relevant event handlers will not be executed. If you want to execute them, you should call .trigger( "change" ) after setting the value.

I found the tutorial Working with UIGestureRecognizers, and I think that is what I am looking for. It helped me come up with the following solution:

-(IBAction) someMethod {
    UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)];
    [panRecognizer setMinimumNumberOfTouches:1];
    [panRecognizer setMaximumNumberOfTouches:1];
    [ViewMain addGestureRecognizer:panRecognizer];
    [panRecognizer release];
}

-(void)move:(UIPanGestureRecognizer*)sender {
    [self.view bringSubviewToFront:sender.view];
    CGPoint translatedPoint = [sender translationInView:sender.view.superview];

    if (sender.state == UIGestureRecognizerStateBegan) {
        firstX = sender.view.center.x;
        firstY = sender.view.center.y;
    }


    translatedPoint = CGPointMake(sender.view.center.x+translatedPoint.x, sender.view.center.y+translatedPoint.y);

    [sender.view setCenter:translatedPoint];
    [sender setTranslation:CGPointZero inView:sender.view];

    if (sender.state == UIGestureRecognizerStateEnded) {
        CGFloat velocityX = (0.2*[sender velocityInView:self.view].x);
        CGFloat velocityY = (0.2*[sender velocityInView:self.view].y);

        CGFloat finalX = translatedPoint.x + velocityX;
        CGFloat finalY = translatedPoint.y + velocityY;// translatedPoint.y + (.35*[(UIPanGestureRecognizer*)sender velocityInView:self.view].y);

        if (finalX < 0) {
            finalX = 0;
        } else if (finalX > self.view.frame.size.width) {
            finalX = self.view.frame.size.width;
        }

        if (finalY < 50) { // to avoid status bar
            finalY = 50;
        } else if (finalY > self.view.frame.size.height) {
            finalY = self.view.frame.size.height;
        }

        CGFloat animationDuration = (ABS(velocityX)*.0002)+.2;

        NSLog(@"the duration is: %f", animationDuration);

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:animationDuration];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDidStopSelector:@selector(animationDidFinish)];
        [[sender view] setCenter:CGPointMake(finalX, finalY)];
        [UIView commitAnimations];
    }
}

you want to make sure that the user selects anything but "Choose an option" (which is the default one). So that it won't validate if you choose the first option. How can this be done?

You can do this by simple adding attribute required = "required" in the select tag. you can see it in below code

<select id="select" required="required">
<option value="">Choose an option</option>
<option value="option1">Option1</option>
<option value="option2">Option2</option>
<option value="option3">Option3</option>
</select>

It worked fine for me at chorme, firefox and internet explorer. Thanks

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

This blog has some really wonderful walkthroughs using windbg and other tools to track down memory leaks of all types. Excellent reading to develop your skills.

You can directly use String.valueOf()

String.valueOf(charSequence)

Though this is same as toString() it does a null check on the charSequence before actually calling toString.

This is useful when a method can return either a charSequence or null value.

You want the zip function.

for (f,b) in zip(foo, bar):
    print "f: ", f ,"; b: ", b

I think the second one should be

var itemList = (from t in ctn.Items
                where !t.Items && t.DeliverySelection
                select t).OrderByDescending(c => c.Delivery.SubmissionDate);

You can access tempfile in Spring by casting if the class of interface MultipartFile is CommonsMultipartFile.

public File getTempFile(MultipartFile multipartFile)
{
    CommonsMultipartFile commonsMultipartFile = (CommonsMultipartFile) multipartFile;
    FileItem fileItem = commonsMultipartFile.getFileItem();
    DiskFileItem diskFileItem = (DiskFileItem) fileItem;
    String absPath = diskFileItem.getStoreLocation().getAbsolutePath();
    File file = new File(absPath);

    //trick to implicitly save on disk small files (<10240 bytes by default)
    if (!file.exists()) {
        file.createNewFile();
        multipartFile.transferTo(file);
    }

    return file;
}

To get rid of the trick with files less than 10240 bytes maxInMemorySize property can be set to 0 in @Configuration @EnableWebMvc class. After that, all uploaded files will be stored on disk.

@Bean(name = "multipartResolver")
    public CommonsMultipartResolver createMultipartResolver() {
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setDefaultEncoding("utf-8");
        resolver.setMaxInMemorySize(0);
        return resolver;
    }

Bit late to the party, but this will get it done. I left the example at 600, as that is what most people will use:

Similar to Shay's example except this also includes max-width to work on the rest of the clients that do have support, as well as a second method to prevent the expansion (media query) which is needed for Outlook '11.

In the head:

  <style type="text/css">
    @media only screen and (min-width: 600px) { .maxW { width:600px !important; } }
  </style>

In the body:

<!--[if (gte mso 9)|(IE)]><table width="600" align="center" cellpadding="0" cellspacing="0" border="0"><tr><td><![endif]-->

Here is another example of this in use: Responsive order confirmation emails for mobile devices?

On 2015-09-25 (after Xcode updates on 2015-09-18):

I used a non-lazy method, but it didn't work. The followings are my tries.

First,

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>www.xxx.yyy.zzz</key>
        <dict>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

And second,

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>www.xxx.yyy.zzz</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

Finally, I used the lazy method:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

It might be a little insecure, but I couldn't find other solutions.

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 28800
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 28800

At first, wait_timeout = 28800 which is the default value. To change the session value, you need to set the global variable because the session variable is read-only.

SET @@GLOBAL.wait_timeout=300

After you set the global variable, the session variable automatically grabs the value.

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 300
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 300

Next time when the server restarts, the session variables will be set to the default value i.e. 28800.

Since your compiler probably doesn't support all of C++11 yet, which supports similar syntax, you're getting these errors because you have to initialize your class members in constructors:

Attribute() : name(5),val(5,0) {}

Global $myArr;
$myArr = array();

function someFuntion(){
    global $myArr;

    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
}

Be forewarned, generally people stick away from globals as it has some downsides.

You could try this

function someFuntion($myArr){
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
    return $myArr;
}
$myArr = someFunction($myArr);

That would make it so you aren't relying on Globals.

There are several ways to do this:

• For a single request:

  let config = {
    headers: {
      header1: value,
    }
  }
  
  let data = {
    'HTTP_CONTENT_LANGUAGE': self.language
  }
  
  axios.post(URL, data, config).then(...)
  

• For setting default global config:

  axios.defaults.headers.post['header1'] = 'value' // for POST requests
  axios.defaults.headers.common['header1'] = 'value' // for all requests
  

• For setting as default on axios instance:

  let instance = axios.create({
    headers: {
      post: {        // can be common or any other method
        header1: 'value1'
      }
    }
  })
  
  //- or after instance has been created
  instance.defaults.headers.post['header1'] = 'value'
  
  //- or before a request is made
  // using Interceptors
  instance.interceptors.request.use(config => {
    config.headers.post['header1'] = 'value';
    return config;
  });
  

I know this is old, but maybe this will help someone else.

Do not log "new" values. Your existing table, GUESTS, has the new values. You'll have double entry of data, plus your DB size will grow way too fast that way.

I cleaned this up and minimized it for this example, but here is the tables you'd need for logging off changes:

CREATE TABLE GUESTS (
      GuestID INT IDENTITY(1,1) PRIMARY KEY, 
      GuestName VARCHAR(50), 
      ModifiedBy INT, 
      ModifiedOn DATETIME
)

CREATE TABLE GUESTS_LOG (
      GuestLogID INT IDENTITY(1,1) PRIMARY KEY, 
      GuestID INT, 
      GuestName VARCHAR(50), 
      ModifiedBy INT, 
      ModifiedOn DATETIME
)

When a value changes in the GUESTS table (ex: Guest name), simply log off that entire row of data, as-is, to your Log/Audit table using the Trigger. Your GUESTS table has current data, the Log/Audit table has the old data.

Then use a select statement to get data from both tables:

SELECT 0 AS 'GuestLogID', GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS] WHERE GuestID = 1
UNION
SELECT GuestLogID, GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS_LOG] WHERE GuestID = 1
ORDER BY ModifiedOn ASC

Your data will come out with what the table looked like, from Oldest to Newest, with the first row being what was created & the last row being the current data. You can see exactly what changed, who changed it, and when they changed it.

Optionally, I used to have a function that looped through the RecordSet (in Classic ASP), and only displayed what values had changed on the web page. It made for a GREAT audit trail so that users could see what had changed over time.

Maybe you can take a look at closure in JavaScript. Here is a working solution:

<!DOCTYPE html>_x000D_
<html>_x000D_
    <head>_x000D_
        <meta charset="utf-8" />_x000D_
        <title>Test</title>_x000D_
    </head>_x000D_
    <body>_x000D_
        <p class="button">Button 0</p>_x000D_
        <p class="button">Button 1</p>_x000D_
        <p class="button">Button 2</p>_x000D_
        <script>_x000D_
            var buttons = document.getElementsByClassName('button');_x000D_
            for (var i=0 ; i < buttons.length ; i++){_x000D_
              (function(index){_x000D_
                buttons[index].onclick = function(){_x000D_
                  alert("I am button " + index);_x000D_
                };_x000D_
              })(i)_x000D_
            }_x000D_
        </script>_x000D_
    </body>_x000D_
</html>

You could do:

var matchingDog = AllDogs.FirstOrDefault(dog => dog.Id == "2"));

This will return the matching dog, else it will return null.

You can then set the property like follows:

if (matchingDog != null)
    matchingDog.Name = "New Dog Name";

It's not possible using CSS, but using a CSS preprocessor like less or SASS.

I don't know what "milliseconds and float seconds" means, but this should give you an idea:

#include <chrono>
#include <thread>
#include <iostream>

int main()
{
  auto then = std::chrono::system_clock::now();
  std::this_thread::sleep_for(std::chrono::seconds(1));
  auto now = std::chrono::system_clock::now();
  auto dur = now - then;
  typedef std::chrono::duration<float> float_seconds;
  auto secs = std::chrono::duration_cast<float_seconds>(dur);
  std::cout << secs.count() << '\n';
}

There is jq for parsing json on the command line:

 jq '.Body'

I had an array of strings and needed an array of the same length of booleans initiated to True. This is what I did

strs = ["Hi","Bye"] 
bools = [ True for s in strs ]

If you want exactly 40 spaces before the string then you should just do:

printf("                                        %s\n", myStr );

If that is too dirty, you can do (but it will be slower than manually typing the 40 spaces): printf("%40s%s", "", myStr );

If you want the string to be lined up at column 40 (that is, have up to 39 spaces proceeding it such that the right most character is in column 40) then do this: printf("%40s", myStr);

You can also put "up to" 40 spaces AfTER the string by doing: printf("%-40s", myStr);

Well, those features are specific to a tool that you are using for development in those languages.

You wouldn't have those tools if (for example) you were using notepad to write code. So, maybe you should ask the question for the tool you are using.

For PHP: http://webservices.xml.com/pub/a/ws/2004/03/24/phpws.html

The class declaration should be in the header file (Or in the source file if not shared).
File: foo.h

class foo
{
    private:
        static int i;
};

But the initialization should be in source file.
File: foo.cpp

int foo::i = 0;

If the initialization is in the header file then each file that includes the header file will have a definition of the static member. Thus during the link phase you will get linker errors as the code to initialize the variable will be defined in multiple source files. The initialisation of the static int i must be done outside of any function.

Note: Matt Curtis: points out that C++ allows the simplification of the above if the static member variable is of const int type (e.g. int, bool, char). You can then declare and initialize the member variable directly inside the class declaration in the header file:

class foo
{
    private:
        static int const i = 42;
};

I changed the package name while coding an update so that I could debug it on my device via Eclipse, without deleting the old version that was installed. Without reverting the package name I was using when trying to reinstall, I got this same error. Using the same package name the reinstall was successful.

"Edit -> EOL Conversion". You can convert to Windows/Linux/Mac EOL there. The current format is displayed in the status bar.

The root issue in my case was a file conflict in the .settings folder. So, deleting the .settings folder would have resolved the Maven error, but I wanted to keep some of my local configuration files. I resolved the conflict, then tried a Maven update again and it worked.

Don't know about git, but in Mercurial I'd just pipe the output of hg log to some sed/perl/whatever script to search for whatever it is you're looking for. You can customize the output of hg log using a template or a style to make it easier to search on, if you wish.

This will include all named branches in the repo. Mercurial does not have something like dangling blobs afaik.

I struggled with this for a while and implemented the PL/SQL solution, but later realized that in Toad you can simply double click on the results grid cell, and it brings up an editor with contents in text. (i'm on Toad v11)

For comparison, I tried transfering a 299GB ntfs disk image from an i5 laptop running Raring Ringtail Ubuntu alpha 2 live cd to an i7 desktop running Ubuntu 12.04.1. Reported speeds:

over wifi + powerline: scp: 5MB/sec (40 Mbit/sec)

over gigabit ethernet + netgear G5608 v3:

scp: 44MB/sec

sftp: 47MB/sec

sftp -C: 13MB/sec

So, over a good gigabit link, sftp is slightly faster than scp, 2010-era fast CPUs seem fast enough to encrypt, but compression isn't a win in all cases.

Over a bad gigabit ethernet link, though, I've had sftp far outperform scp. Something about scp being very chatty, see "scp UNBELIEVABLY slow" on comp.security.ssh from 2008: https://groups.google.com/forum/?fromgroups=#!topic/comp.security.ssh/ldPV3msFFQw http://fixunix.com/ssh/368694-scp-unbelievably-slow.html

If you trust the path, path.resolve is an option:

var path = require('path');

// All other routes should redirect to the index.html
  app.route('/*')
    .get(function(req, res) {
      res.sendFile(path.resolve(app.get('appPath') + '/index.html'));
    });

@aisbaa's answer works if you don't care when the environment variable was declared. If you want the environment variable, even if it has been declared inside of an exec /bin/bash session, use something like:

IFS="=" read -a out <<< $(docker exec container /bin/bash -c "env | grep ENV_VAR" 2>&1)

It's not very pretty, but it gets the job done.

To then get the value, use:

echo ${out[1]}

The other answers normalize an image based on the entire image. But if your image has a predominant color (such as black), it will mask out the features that you're trying to enhance since it will not be as pronounced. To get around this limitation, we can normalize the image based on a subsection region of interest (ROI). Essentially we will normalize based on the section of the image that we want to enhance instead of equally treating each pixel with the same weight. Take for instance this earth image:

Input image -> Normalization based on entire image

If we want to enhance the clouds by normalizing based on the entire image, the result will not be very sharp and will be over saturated due to the black background. The features to enhance are lost. So to obtain a better result we can crop a ROI, normalize based on the ROI, and then apply the normalization back onto the original image. Say we crop the ROI highlighted in green:

This gives us this ROI

The idea is to calculate the mean and standard deviation of the ROI and then clip the frame based on the lower and upper range. In addition, we could use an offset to dynamically adjust the clip intensity. From here we normalize the original image to this new range. Here's the result:

Before -> After

Code

import cv2
import numpy as np

# Load image as grayscale and crop ROI
image = cv2.imread('1.png', 0)
x, y, w, h = 364, 633, 791, 273
ROI = image[y:y+h, x:x+w]

# Calculate mean and STD
mean, STD  = cv2.meanStdDev(ROI)

# Clip frame to lower and upper STD
offset = 0.2
clipped = np.clip(image, mean - offset*STD, mean + offset*STD).astype(np.uint8)

# Normalize to range
result = cv2.normalize(clipped, clipped, 0, 255, norm_type=cv2.NORM_MINMAX)

cv2.imshow('image', image)
cv2.imshow('ROI', ROI)
cv2.imshow('result', result)
cv2.waitKey()

The difference between normalizing based on the entire image vs a specific section of the ROI can be visualized by applying a heatmap to the result. Notice the difference on how the clouds are defined.

Input image -> heatmap

Normalized on entire image -> heatmap

Normalized on ROI -> heatmap

Heatmap code

import matplotlib.pyplot as plt
import numpy as np
import cv2

image = cv2.imread('result.png', 0)
colormap = plt.get_cmap('inferno')
heatmap = (colormap(image) * 2**16).astype(np.uint16)[:,:,:3]
heatmap = cv2.cvtColor(heatmap, cv2.COLOR_RGB2BGR)

cv2.imshow('image', image)
cv2.imshow('heatmap', heatmap)
cv2.waitKey()

Note: The ROI bounding box coordinates were obtained using how to get ROI Bounding Box Coordinates without Guess & Check and heatmap code was from how to convert a grayscale image to heatmap image with Python OpenCV

The easiest way to do this is to format a cell the way you want it, then use the "cell format ..." contextual menu to get to the fill and format colours, use the "more colors ..." button to get to the hexagon colour selector, select the custom tab.

The RGB colours are as in the table at the bottom of the pane. If you prefer HSL values change the color model from RGB to HSL. I have used this to change the saturation on my bad cells. A higher luminosity gives a worse results and the shade of all the cells is the same just the deepness of the colour is modified.

every objects in Objective C conform to NSObject protocol, which holds onto the performSelector: method. I was also previously looking for a way to create some "helper or private" methods that I did not need exposed on a public level. If you want to create a private method with no overhead and not having to define it in your header file then give this a shot...

define the your method with a similar signature as the code below...

-(void)myHelperMethod: (id) sender{
     // code here...
}

then when you need to reference the method simply call it as a selector...

[self performSelector:@selector(myHelperMethod:)];

this line of code will invoke the method you created and not have an annoying warning about not having it defined in the header file.

As tweakt said, Amazon S3 is a good model to work with. Their request signatures do have some features (such as incorporating a timestamp) that help guard against both accidental and malicious request replaying.

The nice thing about HTTP Basic is that virtually all HTTP libraries support it. You will, of course, need to require SSL in this case because sending plaintext passwords over the net is almost universally a bad thing. Basic is preferable to Digest when using SSL because even if the caller already knows that credentials are required, Digest requires an extra roundtrip to exchange the nonce value. With Basic, the callers simply sends the credentials the first time.

Once the identity of the client is established, authorization is really just an implementation problem. However, you could delegate the authorization to some other component with an existing authorization model. Again the nice thing about Basic here is your server ends up with a plaintext copy of the client's password that you can simply pass on to another component within your infrastructure as needed.

In my case the problem was that Xcode was not installed.

You have to write your own transformation. Only decimal, hex and octal numbers are supported with format specifiers.

In my case, this was caused by custom manifest entries added by the maven-jar-plugin.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <archive>
            <index>true</index>
            <manifest>
                <addClasspath>true</addClasspath>
            </manifest>
            <manifestEntries>
                <git>${buildNumber}</git>
                <build-time>${timestamp}</build-time>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>

Removing the following entries fixed the problem

<index>true</index>
<manifest>
    <addClasspath>true</addClasspath>
</manifest>

http://bradmarsh.net/index.php/2008/04/21/sql-2008-change-edit-top-200-rows/

Summary:

• Go to Tools menu -> Options -> SQL Server Object Explorer
• Expand SQL Server Object Explorer
• Choose 'Commands'
• For 'Value for Edit Top Rows' command, specify '0' to edit all rows

Here is another try:

function stringToColor(str){
  var hash = 0;
  for(var i=0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 3) - hash);
  }
  var color = Math.abs(hash).toString(16).substring(0, 6);

  return "#" + '000000'.substring(0, 6 - color.length) + color;
}

Here's the correct way to do it with modern (2014) JQuery:

$(function () {
  $('<script>')
    .attr('type', 'text/javascript')
    .text('some script here')
    .appendTo('head');
})

or if you really want to replace a div you could do:

$(function () {
  $('<script>')
    .attr('type', 'text/javascript')
    .text('some script here')
    .replaceAll('#someelement');
});

You use the sql%rowcount variable.

You need to call it straight after the statement which you need to find the affected row count for.

For example:

set serveroutput ON; 
DECLARE 
    i NUMBER; 
BEGIN 
    UPDATE employees 
    SET    status = 'fired' 
    WHERE  name LIKE '%Bloggs'; 
    i := SQL%rowcount; 
    --note that assignment has to precede COMMIT
    COMMIT; 
    dbms_output.Put_line(i); 
END; 

Two possibilities when this can happen -

1. You have cloned a project and, somehow, the .git directory got deleted or corrupted. This leads Git to be unaware of your local history and will, therefore, cause it to throw this error when you try to push to or pull from the remote repository.

2. You have created a new repository, added a few commits to it, and now you are trying to pull from a remote repository that already has some commits of its own. Git will also throw the error in this case, since it has no idea how the two projects are related.

SOLUTION

The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.

The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?

Once you have the initial ul, you can use the children() method, which will only consider the immediate children of the element. As @activa points out, one way to easily select the root element is to give it a class or an id. The following assumes you have a root ul with id root.

$('ul#root').children('li');

As +Volatility and yourself pointed out, sets are unordered. If you need the elements to be in order, just call sorted on the set:

>>> y = [1, 1, 6, 6, 6, 6, 6, 8, 8]
>>> sorted(set(y))
[1, 6, 8]

a) Modify Visual Studio Code default virtual env path setting. It's called "python.venvPath". You do this by going into code->settings and scroll down for python settings.

b) Restart VS Code

c) Now if you do Shift + Command + P and type Python: Select Interpreter you should see list of your virtual environments.

Check if its not already defined, otherwise defines it on the Date prototype:

if (!Date.prototype.addHours) {
    Date.prototype.addHours = function(h) {
        this.setHours(this.getHours() + h);
        return this;
    };
}

You could also check the request accept content type as specified in the rfc. That way you can render by default HTML and where your client accept application/jason you can return json in your response without a template being required

By the time you say rate = lambda whatever... you've defeated the point of lambda and should just define a function. But, if you want a lambda, you can use 'and' and 'or'

lambda(T): (T>200) and (200*exp(-T)) or (400*exp(-T))

I also have just faced with this problem that how to open existing file. And none of answers was helpful. That's why I tried by myself.

Direction: File -> Open file -> Workspace (with you had chosen first in creating your project) -> Package (which you already created your project in) -> src (source file) -> Created package ->

And now your searching project's nodepad format. I hope it would be helpful. If any mistake here, sorry beforehand.

You can create them just the way others have mentioned. One more point to add: You can even create a skewed two-dimensional array with each row, not necessarily having the same number of collumns, like this:

int array[][] = new int[3][];
array[0] = new int[3];
array[1] = new int[2];
array[2] = new int[5];

Mads Hansen's solution is good but to succeed in reading the external file in .NET 4 took some time to figure out using hints in the comments about resolvers, ProhibitDTD and so on.

This is how it's done:

        XmlReaderSettings settings = new XmlReaderSettings();
        settings.DtdProcessing = DtdProcessing.Parse;
        XmlUrlResolver resolver = new XmlUrlResolver();
        resolver.Credentials = System.Net.CredentialCache.DefaultCredentials;
        settings.XmlResolver = resolver;
        var reader = XmlReader.Create("logfile.xml", settings);
        XmlDocument doc = new XmlDocument();
        doc.Load(reader);
        foreach (XmlElement element in doc.SelectNodes("//event"))
        {
            var ch = element.ChildNodes;
            var count = ch.Count;
        }

logfile.xml:

I think there is a simpler way to make excel wait till the refresh is done, without having to set the Background Query property to False. Why mess with people's preferences right?

Excel 2010 (and later) has this method called CalculateUntilAsyncQueriesDone and all you have to do it call it after you have called the RefreshAll method. Excel will wait till the calculation is complete.

ThisWorkbook.RefreshAll
Application.CalculateUntilAsyncQueriesDone

I usually put these things together to do a master full calculate without interruption, before sending my models to others. Something like this:

ThisWorkbook.RefreshAll
Application.CalculateUntilAsyncQueriesDone
Application.CalculateFullRebuild
Application.CalculateUntilAsyncQueriesDone

As a concept, the head is the latest revision in a branch. If you have more than one head per named branch you probably created it when doing local commits without merging, effectively creating an unnamed branch.

To have a "clean" repository, you should have one head per named branch and always merge to a named branch after you worked locally.

This is also true for Mercurial.

r'a\\nb'.replace('\\\\', '\\')

or

'a\nb'.replace('\n', '\\n')

RadioGroup radioGroup = new RadioGroup(context);
RadioButton radioBtn1 = new RadioButton(context);
RadioButton radioBtn2 = new RadioButton(context);
RadioButton radioBtn3 = new RadioButton(context);

radioBtn1.setText("Less");
radioBtn2.setText("Normal");
radioBtn3.setText("More");

radioGroup.addView(radioBtn1);
radioGroup.addView(radioBtn2);
radioGroup.addView(radioBtn3);
radioBtn2.setChecked(true);

TLDR:

1. Rebooting both application and DB servers is the quickest fix where data volume, network settings and code haven't changed. We always do so as a rule
2. May be indicator of failing hard-drive that needs replacement - check system notifications

I have often encountered this error for various reasons and have had various solutions, including:

1. refactoring my code to use SqlBulkCopy
2. increasing Timeout values, as stated in various answers or checking for underlying causes (may not be data related)
3. Connection Timeout (Default 15s) - How long it takes to wait for a connection to be established with the SQL server before terminating - TCP/PORT related - can go through a troubleshooting checklist (very handy MSDN article)
4. Command Timeout (Default 30s) - How long it takes to wait for the execution of a query - Query execution/network traffic related - also has a troubleshooting process (another very handy MSDN article)
5. Rebooting of the server(s) - both application & DB Server (if separate) - where code and data haven't changed, environment must have changed - First thing you must do. Typically caused by patches (operating system, .Net Framework or SQL Server patches or updates). Particularly if timeout exception appears as below (even if we do not use Azure):
   • System.Data.Entity.Core.EntityException: An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy. ---> System.Data.Entity.Core.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> System.Data.SqlClient.SqlException: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) ---> System.ComponentModel.Win32Exception: The semaphore timeout period has expired

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

All the other solutions unfortunately did not work. This is what worked for me . I simply changed the debugger port to some other port number.

Intelij-> preferences->Build, execution, deployment ->Debugger-> Built in server->port(change value )

This is the solution via multiple replace, which works for any strings (does not need special characters, which are not part of the string).

declare @value varchar(max)
declare @result varchar(max)
set @value = 'alpha   beta gamma  delta       xyz'

set @result = replace(replace(replace(replace(replace(replace(replace(
  @value,'a','ac'),'x','ab'),'  ',' x'),'x ',''),'x',''),'ab','x'),'ac','a')

select @result -- 'alpha beta gamma delta xyz'

As stated earlier by Jamie Dixon, a floated <div> is taken out of normal flow. All content that is still within normal flow will ignore it completely and not make space for it.

Try putting a different colored border border:solid 1px orange; around each of your <div> elements to see what they're doing. You might start by removing the floats and putting some dummy text inside the div. Then style them one at a time to get the desired layout.

One of the best way is a single row of code like this:

In this example we search all PictureBox by name in a form

PictureBox[] picSample = 
                    (PictureBox)this.Controls.Find(PIC_SAMPLE_NAME, true);

Most important is the second paramenter of find.

if you are certain that the control name exists you can directly use it:

  PictureBox picSample = 
                        (PictureBox)this.Controls.Find(PIC_SAMPLE_NAME, true)[0];

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

This was so much easier importing the registry export than what is stated above. + Simply:

1. right click on the file and
2. select "Merge"

Worked like a champ on Win 7 Pro.

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

The below command worked for me

It is very simple, when a function calls itself for accomplishing a task for undefined and finite number of time. An example from my own code, function for populating a with multilevel category tree

function category_tree($parent=0,$sep='')
{
    $q="select id,name from categorye where parent_id=".$parent;
    $rs=mysql_query($q);
    while($rd=mysql_fetch_object($rs))
    {
        echo('id.'">'.$sep.$rd->name.'');
        category_tree($rd->id,$sep.'--');

}

       File[] files = null;
    File file = new File("/storage");// /storage/emulated
if (file.exists()) {
        files = file.listFiles();
            }
            if (null != files)
                for (int j = 0; j < files.length; j++) {
                    Log.e(TAG, "" + files[j]);
                    Log.e(TAG, "//--//--// " +             files[j].exists());

                    if (files[j].toString().replaceAll("_", "")
                            .toLowerCase().contains("extsdcard")) {
                        external_path = files[j].toString();
                        break;
                    } else if (files[j].toString().replaceAll("_", "")
                            .toLowerCase()
                            .contains("sdcard".concat(Integer.toString(j)))) {
                        // external_path = files[j].toString();
                    }
                    Log.e(TAG, "--///--///--  " + external_path);
                }

There are five ways to output text to the console:

Dim StdOut : Set StdOut = CreateObject("Scripting.FileSystemObject").GetStandardStream(1)

WScript.Echo "Hello"
WScript.StdOut.Write "Hello"
WScript.StdOut.WriteLine "Hello"
Stdout.WriteLine "Hello"
Stdout.Write "Hello"

WScript.Echo will output to console but only if the script is started using cscript.exe. It will output to message boxes if started using wscript.exe.

WScript.StdOut.Write and WScript.StdOut.WriteLine will always output to console.

StdOut.Write and StdOut.WriteLine will also always output to console. It requires extra object creation but it is about 10% faster than WScript.Echo.

You will have to set environmental variables properly for each compiler. There are commands on your Program menu for each compiler that does that, while opening a command prompt.

Another option is of course to use the IDE for building your application.

Xamarin port of Felix's answer

In your MainActivity, add this (docs: Android.App.IntentFilterAttribute Class):

....
[IntentFilter(new[] { 
    Intent.ActionView }, 
    Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable }, 
    DataScheme = "my.special.scheme")
]
public class MainActivity : Activity
{
    ....

Xamarin will add following in the AndroidManifest.xml for you:

<activity
    android:label="Something"
    android:screenOrientation="portrait"
    android:theme="@style/MyTheme"
    android:name="blah.MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="my.special.scheme" />
    </intent-filter>
</activity>

And in order to get params (I tested in OnCreate of MainActivity):

var data = Intent.Data;
if (data != null)
{
    var scheme = data.Scheme;
    var host = data.Host;
    var args = data.PathSegments;

    if (args.Count > 0)
    {
        var first = args[0];
        var second = args[1];
        ...
    }
}

As far as I know, above can be added in any activity, not only MainActivity

Notes:

1. When user click on the link, Android OS relaunch your app (kill prev instance, if any, and run new one), means the OnCreate event of app's MainLauncher Activity will be fired again.
2. With this link: <a href="my.special.scheme://host/arg1/arg2">, in above last code snippet values will be:

scheme: my.special.scheme
host: host
args: ["arg1", "arg2"]
first: arg1
second: arg2

Update: if android creates new instance of your app, you should add android:launchMode="singleTask" too.

Follow below steps:

1) First go to Server Explorer in Visual Studio, check if the ".mdf" Data Connections for this project are connected, if so, right click and delete.

2 )Go to Solution Explorer, click show All Files icon.

3) Go to App_Data, right click and delete all ".mdf" files for this project.

4) Delete Migrations folder by right click and delete.

5) Go to SQL Server Management Studio, make sure the DB for this project is not there, otherwise delete it.

6) Go to Package Manager Console in Visual Studio and type:

1. Enable-Migrations -Force
2. Add-Migration init
3. Update-Database

7) Run your application

Note: In step 6 part 3, if you get an error "Cannot attach the file...", it is possibly because you didn't delete the database files completely in SQL Server.

$("a.directions-link").attr("href", $("a.directions-link").attr("href")+"...your additions...");

Using the FM format model modifier to get close, as you won't get the trailing zeros after the decimal separator; but you will still get the separator itself, e.g. 50.. You can use rtrim to get rid of that:

select to_char(a, '99D90'),
    to_char(a, '90D90'),
    to_char(a, 'FM90D99'),
    rtrim(to_char(a, 'FM90D99'), to_char(0, 'D'))
from (
    select 50 a from dual
    union all select 50.57 from dual
    union all select 5.57 from dual
    union all select 0.35 from dual
    union all select 0.4 from dual
)
order by a;

TO_CHA TO_CHA TO_CHA RTRIM(
------ ------ ------ ------
   .35   0.35 0.35   0.35
   .40   0.40 0.4    0.4
  5.57   5.57 5.57   5.57
 50.00  50.00 50.    50
 50.57  50.57 50.57  50.57

Note that I'm using to_char(0, 'D') to generate the character to trim, to match the decimal separator - so it looks for the same character, , or ., as the first to_char adds.

The slight downside is that you lose the alignment. If this is being used elsewhere it might not matter, but it does then you can also wrap it in an lpad, which starts to make it look a bit complicated:

...
lpad(rtrim(to_char(a, 'FM90D99'), to_char(0, 'D')), 6)
...

TO_CHA TO_CHA TO_CHA RTRIM( LPAD(RTRIM(TO_CHAR(A,'FM
------ ------ ------ ------ ------------------------
   .35   0.35 0.35   0.35     0.35
   .40   0.40 0.4    0.4       0.4
  5.57   5.57 5.57   5.57     5.57
 50.00  50.00 50.    50         50
 50.57  50.57 50.57  50.57   50.57

I think you need to use Expr with ->set() (However THIS IS NOT SAFE and you shouldn't do it):

$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
        ->set('u.username', $qb->expr()->literal($username))
        ->set('u.email', $qb->expr()->literal($email))
        ->where('u.id = ?1')
        ->setParameter(1, $editId)
        ->getQuery();
$p = $q->execute();

It's much safer to make all your values parameters instead:

$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
        ->set('u.username', '?1')
        ->set('u.email', '?2')
        ->where('u.id = ?3')
        ->setParameter(1, $username)
        ->setParameter(2, $email)
        ->setParameter(3, $editId)
        ->getQuery();
$p = $q->execute();

The easiest way to do this is just: You will receive a float or double and want it to convert it to the closest round up then just do System.out.println((int)Math.ceil(yourfloat)); it'll work perfectly

Just worked out for another solution as above example have bug( somewhere error ) for me. Variation from the selected answer.

html,body {
    height: 100%
}

#nonFooter {
    min-height: 100%;
    position:relative;
    /* Firefox */
    min-height: -moz-calc(100% - 30px);
    /* WebKit */
    min-height: -webkit-calc(100% - 30px);
    /* Opera */
    min-height: -o-calc(100% - 30px);
    /* Standard */
    min-height: calc(100% - 30px);
}

#footer {
    height:30px;
    margin: 0;
    clear: both;
    width:100%;
    position: relative;
}

for html layout

<body>
    <div id="nonFooter">header,middle,left,right,etc</div>
    <div id="footer"></div>
</body>

Well this way don't support old browser however its acceptable for old browser to scrolldown 30px to view the footer

Look at this:

import datetime

def addYears(date, years):
    result = date + datetime.timedelta(366 * years)
    if years > 0:
        while result.year - date.year > years or date.month < result.month or date.day < result.day:
            result += datetime.timedelta(-1)
    elif years < 0:
        while result.year - date.year < years or date.month > result.month or date.day > result.day:
            result += datetime.timedelta(1)
    print "input: %s output: %s" % (date, result)
    return result

Example usage:

addYears(datetime.date(2012,1,1), -1)
addYears(datetime.date(2012,1,1), 0)
addYears(datetime.date(2012,1,1), 1)
addYears(datetime.date(2012,1,1), -10)
addYears(datetime.date(2012,1,1), 0)
addYears(datetime.date(2012,1,1), 10)

And output of this example:

input: 2012-01-01 output: 2011-01-01
input: 2012-01-01 output: 2012-01-01
input: 2012-01-01 output: 2013-01-01
input: 2012-01-01 output: 2002-01-01
input: 2012-01-01 output: 2012-01-01
input: 2012-01-01 output: 2022-01-01

I would do something like:

$(documento).on('click', '#answer', function() {
  feedback('hey there');
});

$(document).ready(function(){
   $('.somediv').click(function(){
   $(this).addClass('newDiv'); // this means the div which is clicked
   });                         // so instead of using a selector again $('.somediv');
});                           // you use $(this) which much better and neater:=)

On windows (8.1) I killed the virtualbox interface (via taskmgr) and it solved the issue.

Windows 10 on a Network

Having your packages stored on the network drive can slow down the performance of R / R Studio considerably, and you spend a lot of time waiting for the libraries to load/install, due to the bottlenecks of having to retrieve and push data over the server back to your local host. See the following for instructions on how to create an .RProfile on your local machine:

1. Create a directory called C:\Users\xxxxxx\Documents\R\3.4 (or whatever R version you are using, and where you will store your local R packages- your directory location may be different than mine)
2. On R Console, type Sys.getenv("HOME") to get your home directory (this is where your .RProfile will be stored and R will always check there for packages- and this is on the network if packages are stored there)
3. Create a file called .Rprofile and place it in :\YOUR\HOME\DIRECTORY\ON_NETWORK (the directory you get after typing Sys.getenv("HOME") in R Console)
4. File contents of .Rprofile should be like this:

#search 2 places for packages- install new packages to first directory- load built-in packages from the second (this is from your base R package- will be different for some)

.libPaths(c("C:\Users\xxxxxx\Documents\R\3.4", "C:/Program Files/Microsoft/R Client/R_SERVER/library"))

message("*** Setting libPath to local hard drive ***")

#insert a sleep command at line 12 of the unpackPkgZip function. So, just after the package is unzipped.

trace(utils:::unpackPkgZip, quote(Sys.sleep(2)), at=12L, print=TRUE)

message("*** Add 2 second delay when installing packages, to accommodate virus scanner for R 3.4 (fixed in R 3.5+)***")

# fix problem with tcltk for sqldf package: https://github.com/ggrothendieck/sqldf#problem-involvling-tcltk

options(gsubfn.engine = "R")

message("*** Successfully loaded .Rprofile ***")

5. Restart R Studio and verify that you see that the messages above are displayed.

Now you can enjoy faster performance of your application on local host, vs. storing the packages on the network and slowing everything down.

You can use below to clear the screen in terminal: cls; or clr

The declaration and initialization

char *array = "One good thing about music";

declares a pointer array and make it point to a constant array of 31 characters.

The declaration and initialization

char array[] = "One, good, thing, about, music";

declares an array of characters, containing 31 characters.

And yes, the size of the arrays is 31, as it includes the terminating '\0' character.

Laid out in memory, it will be something like this for the first:

+-------+     +------------------------------+
| array | --> | "One good thing about music" |
+-------+     +------------------------------+

And like this for the second:

+------------------------------+
| "One good thing about music" |
+------------------------------+

Arrays decays to pointers to the first element of an array. If you have an array like

char array[] = "One, good, thing, about, music";

then using plain array when a pointer is expected, it's the same as &array[0].

That mean that when you, for example, pass an array as an argument to a function it will be passed as a pointer.

Pointers and arrays are almost interchangeable. You can not, for example, use sizeof(pointer) because that returns the size of the actual pointer and not what it points to. Also when you do e.g. &pointer you get the address of the pointer, but &array returns a pointer to the array. It should be noted that &array is very different from array (or its equivalent &array[0]). While both &array and &array[0] point to the same location, the types are different. Using the arrat above, &array is of type char (*)[31], while &array[0] is of type char *.

For more fun: As many knows, it's possible to use array indexing when accessing a pointer. But because arrays decays to pointers it's possible to use some pointer arithmetic with arrays.

For example:

char array[] = "Foobar";  /* Declare an array of 7 characters */

With the above, you can access the fourth element (the 'b' character) using either

array[3]

or

*(array + 3)

And because addition is commutative, the last can also be expressed as

*(3 + array)

which leads to the fun syntax

3[array]

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

You can encapsulate the list trivially:

using System;
using System.Collections.Generic;
using System.Xml.Serialization;

[XmlRoot("user_list")]
public class UserList
{
    public UserList() {Items = new List<User>();}
    [XmlElement("user")]
    public List<User> Items {get;set;}
}
public class User
{
    [XmlElement("id")]
    public Int32 Id { get; set; }

    [XmlElement("name")]
    public String Name { get; set; }
}

static class Program
{
    static void Main()
    {
        XmlSerializer ser= new XmlSerializer(typeof(UserList));
        UserList list = new UserList();
        list.Items.Add(new User { Id = 1, Name = "abc"});
        list.Items.Add(new User { Id = 2, Name = "def"});
        list.Items.Add(new User { Id = 3, Name = "ghi"});
        ser.Serialize(Console.Out, list);
    }
}

here's what I found with my experiments using the built-in

FORMATMESSAGE() function

sp_addmessage @msgnum=50001,@severity=1,@msgText='Hello %s you are #%d',@replace='replace'
SELECT FORMATMESSAGE(50001, 'Table1', 5)

when you call up sp_addmessage, your message template gets stored into the system table master.dbo.sysmessages (verified on SQLServer 2000).

You must manage addition and removal of template strings from the table yourself, which is awkward if all you really want is output a quick message to the results screen.

The solution provided by Kathik DV, looks interesting but doesn't work with SQL Server 2000, so i altered it a bit, and this version should work with all versions of SQL Server:

IF OBJECT_ID( N'[dbo].[FormatString]', 'FN' ) IS NOT NULL
    DROP FUNCTION [dbo].[FormatString]
GO
/***************************************************

Original Author : Karthik D V http://stringformat-in-sql.blogspot.com/
Sample Call:

*******************************************/
CREATE FUNCTION [dbo].[FormatString](

    DECLARE @Message NVARCHAR(400), @Delimiter CHAR(1)
    DECLARE @ParamTable TABLE ( ID INT IDENTITY(0,1), Parameter VARCHAR(1000) )
    Declare @startPos int, @endPos int
    SELECT @Message = @Format, @Delimiter = ','

    --handle first parameter
     set @endPos=CHARINDEX(@Delimiter,@Parameters)
    if (@endPos=0 and @Parameters is not null) --there is only one parameter
        insert into @ParamTable (Parameter) values(@Parameters)
    else begin
        insert into @ParamTable (Parameter) select substring(@Parameters,0,@endPos)
    end

    while @endPos>0
    Begin
        --insert a row for each parameter in the 
        set @startPos = @endPos + LEN(@Delimiter)
        set @endPos = CHARINDEX(@Delimiter,@Parameters, @startPos)
        if (@endPos>0)
            insert into @ParamTable (Parameter) select substring(@Parameters,@startPos,@endPos)
        else
            insert into @ParamTable (Parameter) select substring(@Parameters,@startPos,4000)            
    End

    UPDATE @ParamTable SET @Message = REPLACE ( @Message, '{'+CONVERT(VARCHAR,ID) + '}', Parameter )
    RETURN @Message
END
Go
    grant execute,references on dbo.formatString to public

Usage:

print dbo.formatString('hello {0}... you are {1}','world,good')
--result: hello world... you are good

simple just use the img tag helper. Rails knows to look in the images folder in the asset pipeline, you can use it like this

<%= image_tag "image.jpg" %>

Edit:

It actually just occurred to me that in Xcode 7b4, UI testing now has expectationForPredicate:evaluatedWithObject:handler:

Original:

Another way is to spin the run loop for a set amount of time. Really only useful if you know how much (estimated) time you'll need to wait for

Obj-C: [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow: <<time to wait in seconds>>]]

Swift: NSRunLoop.currentRunLoop().runMode(NSDefaultRunLoopMode, beforeDate: NSDate(timeIntervalSinceNow: <<time to wait in seconds>>))

This is not super useful if you need to test some conditions in order to continue your test. To run conditional checks, use a while loop.

It can be understood like this:

var a= []; //creates a new empty array
var a= {}; //creates a new empty object

You can also understand that

var a = {}; is equivalent to var a= new Object();

Note:

You can use Arrays when you are bothered about the order of elements(of same type) in your collection else you can use objects. In objects the order is not guaranteed.

dynamic_cast has runtime type checking and only works with references and pointers, whereas static_cast does not offer runtime type checking. For complete information, see the MSDN article static_cast Operator.

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

Two and a half years late is better than never, right?

int System.in.read() reads the next byte of data from the input stream. But I am sure you already knew that, because it is trivial to look up. So, what you are probably asking is:

• Why is it declared to return an int when the documentation says that it reads a byte?

• and why does it appear to return garbage? (I type '9', but it returns 57.)

It returns an int because besides all the possible values of a byte, it also needs to be able to return an extra value to indicate end-of-stream. So, it has to return a type which can express more values than a byte can.

^{Note: They could have made it a short, but they opted for int instead, possibly as a tip of the hat of historical significance to C, whose getc() function also returns an int, but more importantly because short is a bit cumbersome to work with, (the language offers no means of specifying a short literal, so you have to specify an int literal and cast it to short,) plus on certain architectures int has better performance than short.}

It appears to return garbage because when you view a character as an integer, what you are looking at is the ASCII^(*) value of that character. So, a '9' appears as a 57. But if you cast it to a character, you get '9', so all is well.

^{Think of it this way: if you typed the character '9' it is nonsensical to expect System.in.read() to return the number 9, because then what number would you expect it to return if you had typed an 'a'? Obviously, characters must be mapped to numbers. ASCII(*) is a system of mapping characters to numbers. And in this system, character '9' maps to number 57, not number 9.}

(*) Not necessarily ASCII; it may be some other encoding, like UTF-16; but in the vast majority of encodings, and certainly in all popular encodings, the first 127 values are the same as ASCII. And this includes all english alphanumeric characters and popular symbols.

Actually, there are many issues with different environments, python versions, so on. You might also need to install python dev files, so to 'brute-force' the installation I would run all of these:

sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient

You should be good to go with the accepted answer. And can remove the unnecessary packages if that's important to you.

Flexbox? You can use flexbox.

.box {_x000D_

git remote manpage is pretty straightforward:

• https://www.kernel.org/pub/software/scm/git/docs/git-remote.html

Use

Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream

Then do:    
$ git remote add upstream https://github.com/Foo/repos.git

or just update the URL directly:

$ git remote set-url upstream https://github.com/Foo/repos.git

or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).

...
[remote "upstream"]
    fetch = +refs/heads/*:refs/remotes/upstream/*
    url = https://github.com/foo/repos.git

* Regarding 'git remote rm' vs 'git remote remove' - this changed around git 1.7.10.3 / 1.7.12 2 - see

https://code.google.com/p/git-core/source/detail?spec=svne17dba8fe15028425acd6a4ebebf1b8e9377d3c6&r=e17dba8fe15028425acd6a4ebebf1b8e9377d3c6

Log message

remote: prefer subcommand name 'remove' to 'rm'

All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.

'rm' is still supported and used in the test suite. It's just not
widely advertised.

This is a two step process:

1. Remove tracking of file/folder - but keep them on disk - using

   git rm --cached 
   

   Now they do not show up as "changed" but still show as

       untracked files in  git status -u  
   

2. Add them to .gitignore

If the issue persist in ASP.NET,All I had to do was change the "Enable 32-bit Applications" setting to True, in the Advanced Settings for the Application Pool.

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

var dict = File.ReadLines("test.txt")
               .Where(line => !string.IsNullOrWhitespace(line))
               .Select(line => line.Split(new char[] { '=' }, 2, 0))
               .ToDictionary(parts => parts[0], parts => parts[1]);


or 

    enter code here

line="[email protected][email protected]";
string[] tokens = line.Split(new char[] { '=' }, 2, 0);

ans:
tokens[0]=to
token[1][email protected][email protected]"

Another way to accomplish the same thing...

List<Car> distinticBy = cars
    .Select(car => car.CarCode)
    .Distinct()
    .Select(code => cars.First(car => car.CarCode == code))
    .ToList();

It's possible to create an extension method to do this in a more generic way. It would be interesting if someone could evalute performance of this 'DistinctBy' against the GroupBy approach.

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

sudo sh -c "echo 127.0.0.1 localhost >> /etc/hosts"

Try to use:

Worksheets.Add (After:=Worksheets(Worksheets.Count)).Name = "MySheet"

If you want to check whether a sheet with the same name already exists, you can create a function:

Function funcCreateList(argCreateList)
    For Each Worksheet In ThisWorkbook.Worksheets
        If argCreateList = Worksheet.Name Then
            Exit Function ' if found - exit function
        End If
    Next Worksheet
    Worksheets.Add (After:=Worksheets(Worksheets.Count)).Name = argCreateList
End Function

When the function is created, you can call it from your main Sub, e.g.:

Sub main

    funcCreateList "MySheet"

Exit Sub

Using tee

 awk '{awk code}' file | tee file

the tee command take place and executed after the awk command is finished due to the |.

Well, you don't need to buffer both values - only one:

var tmp = list[x];
list[x] = list[y];
list[y] = tmp;

In my case, I wanted to center in a parent container with position: absolute.

<div class="absolute-container">
    <div class="parent-container">
        <div class="centered-content">
            My content
        </div>
    </div>
</div>

I had to add some positioning for top, bottom, left & right.

.absolute-container {
    position:absolute;
    top:0;
    left:0;
    bottom:0;
    right:0;
}

.parent-container {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}

.centered-content {
    display: table-cell;
    text-align: center;
    vertical-align: middle
}

Prikrutil, I think we're on the same boat. I also come to Scala from Erlang. I like Nitrogen a lot so I decided to created a Scala web framework inspired by it.

Take a look at Xitrum. Its doc is quite extensive. From README:

Xitrum is an async and clustered Scala web framework and web server on top of Netty and Hazelcast:

• It fills the gap between Scalatra and Lift: more powerful than Scalatra and easier to use than Lift. You can easily create both RESTful APIs and postbacks. Xitrum is controller-first like Scalatra, not view-first like Lift.
• Annotation is used for URL routes, in the spirit of JAX-RS. You don't have to declare all routes in a single place.
• Typesafe, in the spirit of Scala.
• Async, in the spirit of Netty.
• Sessions can be stored in cookies or clustered Hazelcast.
• jQuery Validation is integrated for browser side and server side validation. i18n using GNU gettext, which means unlike most other solutions, both singular and plural forms are supported.
• Conditional GET using ETag.

Hazelcast also gives:

• In-process and clustered cache, you don't need separate cache servers.
• In-process and clustered Comet, you can scale Comet to multiple web servers.

Follow the tutorial for a quick start.

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

To play a notification sound using python, call a music player, such as vlc. VLC prompted me to use its commandline version, cvlc, instead.

from subprocess import call
call(["cvlc", "--play-and-exit", "myNotificationTone.mp3"])

It requires vlc to be preinstalled on the device. Tested on Linux(Ubuntu 16.04 LTS); Running Python 3.5.

The Arrays class has versions of sort() and binarySearch() which don't require a Comparator. For example, you can use the version of Arrays.sort() which just takes an array of objects. These methods call the compareTo() method of the objects in the array.

When you have multiple submit buttons in a single form and a user presses the ENTER key to submit the form from a text field, this code overrides default functionality, by calling the submit event on the form from the key press event. Here is that code:

$('form input').keypress(function(e){

    if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)){ $(e.target).closest('form').submit(); return false; }
    else return true;

});

My solution was to use a short nickname (less than 31 characters) and then write the entire name in cell 0.

It can be achieved if you are using a string resource xml file, which supports HTML tags like <b></b>, <i></i> and <u></u>.

<resources>
    <string name="your_string_here">This is an <u>underline</u>.</string>
</resources>

If you want to underline something from code use:

TextView textView = (TextView) view.findViewById(R.id.textview);
SpannableString content = new SpannableString("Content");
content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
textView.setText(content);

Try this:

string decodedUrl = HttpUtility.UrlDecode("my.aspx?val=%2Fxyz2F");

Add a comma separated list of classes like this :

jQuery(document).ready(function($) {

$('.class, .id').click(function() { 

//  Your code

    }

});

f is an (instance) method. However, you are calling it via fibo.f, where fibo is the class object. Hence, f is unbound (not bound to any class instance).

If you did

a = fibo()
a.f()

then that f is bound (to the instance a).

Try ^CTR.\*, which literally means start of line, CTR, anything.

This will be case-sensitive, and setting non-case-sensitivity will depend on your programming language, or use ^[Cc][Tt][Rr].\* if cross-environment case-insensitivity matters.

One way that I've found really useful in situations like this is to go old-school and use the Jet OLEDB provider, together with a schema.ini file to read large tab-delimited files in using ADO.Net. Obviously, this method is really only useful if you know the format of the file to be imported.

public void ImportCsvFile(string filename)
{
    FileInfo file = new FileInfo(filename);

    using (OleDbConnection con = 
            new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\"" +
            file.DirectoryName + "\";
            Extended Properties='text;HDR=Yes;FMT=TabDelimited';"))
    {
        using (OleDbCommand cmd = new OleDbCommand(string.Format
                                  ("SELECT * FROM [{0}]", file.Name), con))
        {
            con.Open();

            // Using a DataReader to process the data
            using (OleDbDataReader reader = cmd.ExecuteReader())
            {
                while (reader.Read())
                {
                    // Process the current reader entry...
                }
            }

            // Using a DataTable to process the data
            using (OleDbDataAdapter adp = new OleDbDataAdapter(cmd))
            {
                DataTable tbl = new DataTable("MyTable");
                adp.Fill(tbl);

                foreach (DataRow row in tbl.Rows)
                {
                    // Process the current row...
                }
            }
        }
    }
} 

Once you have the data in a nice format like a datatable, filtering out the data you need becomes pretty trivial.

You are getting close!

# Find all of the text between paragraph tags and strip out the html
page = soup.find('p').getText()

Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like

soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})

to zero in on the body of the article.

Look at how Runtime.getRuntime().exec() passes the String command to the ProcessBuilder. It uses a tokenizer and explodes the command into individual tokens, then invokes exec(String[] cmdarray, ......) which constructs a ProcessBuilder.

If you construct the ProcessBuilder with an array of strings instead of a single one, you'll get to the same result.

The ProcessBuilder constructor takes a String... vararg, so passing the whole command as a single String has the same effect as invoking that command in quotes in a terminal:

shell$ "command with args"

With JDBC, that error usually occurs because your JDBC driver implements an older version of the JDBC API than the one included in your JRE. These older versions are fine so long as you don't try and use a method that appeared in the newer API.

I'm not sure what version of JDBC setBinaryStream appeared in. It's been around for a while, I think.

Regardless, your JDBC driver version (10.2.0.4.0) is quite old, I recommend upgrading it to the version that was released with 11g (download here), and try again.

What I learnt from this question and the answers. Thanks all!

Let say I have these variables and functions:

$functionName1 = "sayHello";
$functionName2 = "sayHelloTo";
$functionName3 = "saySomethingTo";

$friend = "John";
$datas = array(
    "something"=>"how are you?",
    "to"=>"Sarah"
);

function sayHello()
{
echo "Hello!";
}

function sayHelloTo($to)
{
echo "Dear $to, hello!";
}

function saySomethingTo($something, $to)
{
echo "Dear $to, $something";
}

1. To call function without arguments

   // Calling sayHello()
   call_user_func($functionName1); 
   

   Hello!

2. To call function with 1 argument

   // Calling sayHelloTo("John")
   call_user_func($functionName2, $friend);
   

   Dear John, hello!

3. To call function with 1 or more arguments This will be useful if you are dynamically calling your functions and each function have different number of arguments. This is my case that I have been looking for (and solved). call_user_func_array is the key

   Dear Sarah, how are you?

Yay bye!

Yes, the higher the z-index, the better. It will position your content element on top of every other element on the page. Say you have z-index to some elements on your page. Look for the highest and then give a higher z-index to your popup element. This way it will flow even over the other elements with z-index. If you don't have a z-index in any element on your page, you should give like z-index:2; or something higher.

You can simply get the text in editText by applying below code:

EditText editText=(EditText)findViewById(R.id.vnosZadeve);
String text=editText.getText().toString();

then you can toast string text!

Happy coding!

UINavigationBar.appearance().barTintColor

worked for me

Another difference is that <import> allows importing by referring to another namespace. <include> only allows importing by referring to a URI of intended include schema. That is definitely another difference than inter-intra namespace importing.

For example, the xml schema validator may already know the locations of all schemas by namespace already. Especially considering that referring to XML namespaces by URI may be problematic on different systems where classpath:// means nothing, or where http:// isn't allowed, or where some URI doesn't point to the same thing as it does on another system.

Code sample of valid and invalid imports and includes:

Valid:

<xsd:import namespace="some/name/space"/>
<xsd:import schemaLocation="classpath://mine.xsd"/>

<xsd:include schemaLocation="classpath://mine.xsd"/>

Invalid:

<xsd:include namespace="some/name/space"/>

@Ajax.ActionLink requires jQuery AJAX Unobtrusive library. You can download it via nuget:

Install-Package Microsoft.jQuery.Unobtrusive.Ajax

Then add this code to your View:

@Scripts.Render("~/Scripts/jquery.unobtrusive-ajax.min.js")

This bash script does ssh into a target remote machine, and run some command in the remote machine, do not forget to install expect before running it (on mac brew install expect )

#!/usr/bin/expect
set username "enterusenamehere"
set password "enterpasswordhere"
set hosts "enteripaddressofhosthere"
spawn ssh  $username@$hosts
expect "$username@$hosts's password:"
send -- "$password\n"
expect "$"
send -- "somecommand on target remote machine here\n"
sleep 5
expect "$"
send -- "exit\n"

For those that do know the width, you could do something like

div {
     max-width: ???px; //px,%
     margin-left:auto;
     margin-right:auto;
}

I also agree about not setting text-align:center on the body because it can mess up the rest of your code and you might have to individually set text-align:left on a lot of things either then or in the future.

You can read multiple variables from file like this:

for /f "delims== tokens=1,2" %%G in (param.txt) do set %%G=%%H

where param.txt:

PARAM1=value1
PARAM2=value2
...

When filtering a DataFrame with string values, I find that the pyspark.sql.functions lower and upper come in handy, if your data could have column entries like "foo" and "Foo":

import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))

try this to close the connection:

socket.close();

and if you want to open it again:

socket.connect();

Current best practice (tidyverse) is:

require(dplyr)
df1 %>% count(Year, Month)

Per the Android docs SystemClock.elapsedRealtime() is the recommend basis for general purpose interval timing. This is because, per the documentation, elapsedRealtime() is guaranteed to be monotonic, [...], so is the recommend basis for general purpose interval timing.

The SystemClock documentation has a nice overview of the various time methods and the applicable use cases for them.

• SystemClock.elapsedRealtime() and SystemClock.elapsedRealtimeNanos() are the best bet for calculating general purpose elapsed time.
• SystemClock.uptimeMillis() and System.nanoTime() are another possibility, but unlike the recommended methods, they don't include time in deep sleep. If this is your desired behavior then they are fine to use. Otherwise stick with elapsedRealtime().
• Stay away from System.currentTimeMillis() as this will return "wall" clock time. Which is unsuitable for calculating elapsed time as the wall clock time may jump forward or backwards. Many things like NTP clients can cause wall clock time to jump and skew. This will cause elapsed time calculations based on currentTimeMillis() to not always be accurate.

When the game starts:

long startTime = SystemClock.elapsedRealtime();

When the game ends:

long endTime = SystemClock.elapsedRealtime();
long elapsedMilliSeconds = endTime - startTime;
double elapsedSeconds = elapsedMilliSeconds / 1000.0;

Also, Timer() is a best effort timer and will not always be accurate. So there will be an accumulation of timing errors over the duration of the game. To more accurately display interim time, use periodic checks to System.currentTimeMillis() as the basis of the time sent to setText(...).

Also, instead of using Timer, you might want to look into using TimerTask, this class is designed for what you want to do. The only problem is that it counts down instead of up, but that can be solved with simple subtraction.

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

better way is to reuse ANDROID_HOME variable in path variable. if your ANDROID_HOME variable changes you just have to make change at one place.

export ANDROID_HOME=/home/arshid/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

It wont break if you wrap each item in a div. Check out my fiddle with the link below. I made the width of the fieldset 125px and made each item 50px wide. You'll see the label and checkbox remain side by side on a new line and don't break.

<fieldset>
<div class="item">
    <input type="checkbox" id="a">
    <label for="a">a</label>
</div>
<div class="item">
   <input type="checkbox" id="b">
<!-- depending on width, a linebreak can occur here. -->
    <label for="b">bgf bh fhg fdg hg dg gfh dfgh</label>
</div>
<div class="item">
    <input type="checkbox" id="c">
    <label for="c">c</label>
</div>
</fieldset>

Directly from the node.js tag wiki, make sure watch some of the talk videos linked there to get a better idea.

Node.js is an event based, asynchronous I/O framework that uses Google's V8 JavaScript Engine.

Node.js - or just Node as it's commonly called - is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code and the lack of context switching.

It's also possible to use matured JavaScript frameworks like YUI and jQuery for server side DOM manipulation.

To ease the development of complex JavaScript further, Node.js supports the CommonJS standard that allows for modularized development and the distribution of software in packages via the Node Package Manager.

Applications that can be written using Node.js include, but are not limited to:

• Static file servers
• Web Application frameworks
• Messaging middle ware
• Servers for HTML5 multi player games

There is no error event for the script tag. You can tell when it is successful, and assume that it has not loaded after a timeout:

<script type="text/javascript" onload="loaded=1" src="....js"></script>

I had the same issue but in my case, implemented class was accidently become 'abstract' as a result autowiring was failing.

Another option is using msmtp.

What you need is to set up your .msmtprc with something like this (example is using gmail):

account default
host smtp.gmail.com
port 587
from [email protected]
tls on
tls_starttls on
tls_trust_file ~/.certs/equifax.pem
auth on
user [email protected]
password <password>
logfile ~/.msmtp.log

Then just call:

(echo "Subject: <subject>"; echo; echo "<message>") | msmtp <[email protected]>

in your script

Update: For HTML mail you have to put the headers as well, so you might want to make a file like this:

From: [email protected]
To: [email protected]
Subject: Important message
Mime-Version: 1.0
Content-Type: text/html

<h1>Mail body will be here</h1>
The mail body <b>should</b> start after one blank line from the header.

And mail it like

cat email-template | msmtp [email protected]

The same can be done via command line as well, but it might be easier using a file.

Redirect non-www to www

For Single Domain :

server {
        server_name example.com;
        return 301 $scheme://www.example.com$request_uri;
}

For All Domains :

server {
        server_name "~^(?!www\.).*" ;
        return 301 $scheme://www.$host$request_uri;
}

Redirect www to non-www For Single Domain:

server {
        server_name www.example.com;
        return 301 $scheme://example.com$request_uri;
}

For All Domains :

server {
         server_name "~^www\.(.*)$" ;
         return 301 $scheme://$1$request_uri ;
}

To have a cron executed on Sunday you can use either of these:

5 8 * * 0
5 8 * * 7
5 8 * * Sun

Where 5 8 stands for the time of the day when this will happen: 8:05.

In general, if you want to execute something on Sunday, just make sure the 5th column contains either of 0, 7 or Sun. You had 6, so it was running on Saturday.

The format for cronjobs is:

 +---------------- minute (0 - 59)
 |  +------------- hour (0 - 23)
 |  |  +---------- day of month (1 - 31)
 |  |  |  +------- month (1 - 12)
 |  |  |  |  +---- day of week (0 - 6) (Sunday=0 or 7)
 |  |  |  |  |
 *  *  *  *  *  command to be executed

You can always use crontab.guru as a editor to check your cron expressions.

yes there is!

$(function () {
    $("#first").animate({
       width: '200px'
    }, { duration: 200, queue: false });

    $("#second").animate({
       width: '600px'
    }, { duration: 200, queue: false });
});

In my case, LoginActivity was closed as well. As a result,

Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK

did not help.

However, setting

Intent.FLAG_ACTIVITY_NEW_TASK

helped me.

The only time I've ever used this in practice is with numpy/pandas. For example, with the .isin() dataframe method.

In the docs they show this basic example

>>> df.isin([0, 2])
        num_legs  num_wings
falcon      True       True
dog        False       True

But what if instead you wanted all the rows not in [0, 2]?

>>> ~df.isin([0, 2])
        num_legs  num_wings
falcon     False       False
dog        True        False

I threw this together so that you could do some querying on the results

Declare @dbName varchar(150)
set @dbName = '[YOURDATABASENAME]'

--Total machine connections
--SELECT  COUNT(dbid) as TotalConnections FROM sys.sysprocesses WHERE dbid > 0

--Available connections
DECLARE @SPWHO1 TABLE (DBName VARCHAR(1000) NULL, NoOfAvailableConnections VARCHAR(1000) NULL, LoginName VARCHAR(1000) NULL)
INSERT INTO @SPWHO1 
    SELECT db_name(dbid), count(dbid), loginame FROM sys.sysprocesses WHERE dbid > 0 GROUP BY dbid, loginame
SELECT * FROM @SPWHO1 WHERE DBName = @dbName

--Running connections
DECLARE @SPWHO2 TABLE (SPID VARCHAR(1000), [Status] VARCHAR(1000) NULL, [Login] VARCHAR(1000) NULL, HostName VARCHAR(1000) NULL, BlkBy VARCHAR(1000) NULL, DBName VARCHAR(1000) NULL, Command VARCHAR(1000) NULL, CPUTime VARCHAR(1000) NULL, DiskIO VARCHAR(1000) NULL, LastBatch VARCHAR(1000) NULL, ProgramName VARCHAR(1000) NULL, SPID2 VARCHAR(1000) NULL, Request VARCHAR(1000) NULL)
INSERT INTO @SPWHO2 
    EXEC sp_who2 'Active'
SELECT * FROM @SPWHO2 WHERE DBName = @dbName

The simplest way is

<li class="{{ Request::is('contacts/*') ? 'active' : '' }}">Dashboard</li>

This colud capture the contacts/, contacts/create, contacts/edit...

In python, this concatenates with blank lines between files (the , suppresses adding an extra trailing blank line):

print '\n'.join(open(f).read() for f in filenames),

Here is the ugly python one-liner that can be called from the shell and prints the output to a file:

python -c "from sys import argv; print '\n'.join(open(f).read() for f in argv[1:])," File*.txt > finalfile.txt

There are different Names of SD-Cards.

This Code check every possible Name (I don't guarantee that these are all names but the most are included)

It prefers the main storage.

 private String SDPath() {
    String sdcardpath = "";

    //Datas
    if (new File("/data/sdext4/").exists() && new File("/data/sdext4/").canRead()){

        sdcardpath = "/data/sdext2/";
    }
    if (new File("/data/sdext1/").exists() && new File("/data/sdext1/").canRead()){
        sdcardpath = "/data/sdext1/";
    }
    if (new File("/data/sdext/").exists() && new File("/data/sdext/").canRead()){
        sdcardpath = "/data/sdext/";
    }

    if (new File("mnt/emmc/").exists() && new File("mnt/emmc/").canRead()){
        sdcardpath = "mnt/emmc/";
    }

    }

    //Storages
    if (new File("/storage/removable/sdcard1/").exists() && new File("/storage/removable/sdcard1/").canRead()){
        sdcardpath = "/storage/removable/sdcard1/";
    }
    if (new File("/storage/external_SD/").exists() && new File("/storage/external_SD/").canRead()){
        sdcardpath = "/storage/external_SD/";
    }
    if (new File("/storage/ext_sd/").exists() && new File("/storage/ext_sd/").canRead()){
        sdcardpath = "/storage/ext_sd/";

    if (new File("/storage/sdcard1/").exists() && new File("/storage/sdcard1/").canRead()){
        sdcardpath = "/storage/sdcard1/";
    }
    if (new File("/storage/sdcard0/").exists() && new File("/storage/sdcard0/").canRead()){
        sdcardpath = "/storage/sdcard0/";

    if (new File("/storage/sdcard/").exists() && new File("/storage/sdcard/").canRead()){
        sdcardpath = "/storage/sdcard/";
    }
    if (sdcardpath.contentEquals("")){
        sdcardpath = Environment.getExternalStorageDirectory().getAbsolutePath();
    }

    Log.v("SDFinder","Path: " + sdcardpath);
    return sdcardpath;
}

Seekbar called onProgressChanged method when we initialize first time. We can skip by using below code We need to check boolean it return false when initialize automatically

volumeManager.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
                if(b){
                    mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, i, 0);
                }
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });

Another option could be using bootstrap select. On their own words:

A custom select / multiselect for Bootstrap using button dropdown, designed to behave like regular Bootstrap selects.
