Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

UPD 19.03.2019 Here is a version for browser on GitHub.

I’m tired of looking for free translators and the best option for me was Selenium (more precisely selenide and webdrivermanager) and https://translate.google.com

import io.github.bonigarcia.wdm.ChromeDriverManager;
import com.codeborne.selenide.Configuration;
import io.github.bonigarcia.wdm.DriverManagerType;
import static com.codeborne.selenide.Selenide.*;

public class Main {

    public static void main(String[] args) throws IOException, ParseException {

        ChromeDriverManager.getInstance(DriverManagerType.CHROME).version("76.0.3809.126").setup();
        Configuration.startMaximized = true;
        open("https://translate.google.com/?hl=ru#view=home&op=translate&sl=en&tl=ru");
        String[] strings = /some strings to translate
        for (String data: strings) {
            $x("//textarea[@id='source']").clear();
            $x("//textarea[@id='source']").sendKeys(data);
            String translation = $x("//span[@class='tlid-translation translation']").getText();
        }
    }
}

<div id="google_translate_element"></div><script type="text/javascript">
function googleTranslateElementInit() {
  new google.translate.TranslateElement({pageLanguage: 'en', includedLanguages: 'ar', layout: google.translate.TranslateElement.InlineLayout.SIMPLE}, 'google_translate_element');
}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

You can't use CSS to disable autocomplete, but you can use HTML:

<input type="text" autocomplete="false" />

Technically you can replace false with any invalid value and it'll work. This iOS the only solution I've found which also works in Edge.

Short version Plunker:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `
      <input #myInput type="file" placeholder="File Name" name="filename">
      <button (click)="myInput.value = ''">Reset</button>
  `
})
export class AppComponent {


}

And i think more common case is to not using button but do reset automatically. Angular Template statements support chaining expressions so Plunker:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `
      <input #myInput type="file" (change)="onChange(myInput.value, $event); myInput.value = ''" placeholder="File Name" name="filename">
  `
})
export class AppComponent {

  onChange(files, event) {
    alert( files );
    alert( event.target.files[0].name );
  }

}

And interesting link about why there is no recursion on value change.

You can sort the array first, and then loop through it twice, once in both directions:

Arrays.sort(arr); 
System.out.print("Numbers in Ascending Order:" ); 
for(int i = 0; i < arr.length; i++){ 
  System.out.print( " " + arr[i]); 
} 
System.out.print("Numbers in Descending Order: " ); 
for(int i = arr.length - 1; i >= 0; i--){ 
  System.out.print( " " + arr[i]); 
} 

You can accomplish this with :before and :after without knowing the width of container or background color, and using them allows for greater styling of the line breaks. For example, this can be modified to make double-lines, dotted lines, etc.

Encapsulation is a way to achieve "information hiding" so, following your example, you don't "need to know the internal working of the mobile phone to operate" with it. You have an interface to use the device behaviour without knowing implementation details.

Abstraction on the other side, can be explained as the capability to use the same interface for different objects. Different implementations of the same interface can exist. Details are hidden by encapsulation.

Let me explain why sleep infinity works though it is not documented. jp48's answer is also useful.

The most important thing: By specifying inf or infinity (both case-insensitive), you can sleep for the longest time your implementation permits (i.e. the smaller value of HUGE_VAL and TYPE_MAXIMUM(time_t)).

Now let's dig into the details. The source code of sleep command can be read from coreutils/src/sleep.c. Essentially, the function does this:

double s; //seconds
xstrtod (argv[i], &p, &s, cl_strtod); //`p` is not essential (just used for error check).
xnanosleep (s);

Understanding xstrtod (argv[i], &p, &s, cl_strtod)

xstrtod()

According to gnulib/lib/xstrtod.c, the call of xstrtod() converts string argv[i] to a floating point value and stores it to *s, using a converting function cl_strtod().

cl_strtod()

As can be seen from coreutils/lib/cl-strtod.c, cl_strtod() converts a string to a floating point value, using strtod().

strtod()

According to man 3 strtod, strtod() converts a string to a value of type double. The manpage says

The expected form of the (initial portion of the) string is ... or (iii) an infinity, or ...

and an infinity is defined as

An infinity is either "INF" or "INFINITY", disregarding case.

Although the document tells

If the correct value would cause overflow, plus or minus HUGE_VAL (HUGE_VALF, HUGE_VALL) is returned

, it is not clear how an infinity is treated. So let's see the source code gnulib/lib/strtod.c. What we want to read is

else if (c_tolower (*s) == 'i'
         && c_tolower (s[1]) == 'n'
         && c_tolower (s[2]) == 'f')
  {
    s += 3;
    if (c_tolower (*s) == 'i'
        && c_tolower (s[1]) == 'n'
        && c_tolower (s[2]) == 'i'
        && c_tolower (s[3]) == 't'
        && c_tolower (s[4]) == 'y')
      s += 5;
    num = HUGE_VAL;
    errno = saved_errno;
  }

Thus, INF and INFINITY (both case-insensitive) are regarded as HUGE_VAL.

HUGE_VAL family

Let's use N1570 as the C standard. HUGE_VAL, HUGE_VALF and HUGE_VALL macros are defined in §7.12-3

The macro
    HUGE_VAL
expands to a positive double constant expression, not necessarily representable as a float. The macros
    HUGE_VALF
    HUGE_VALL
are respectively float and long double analogs of HUGE_VAL.

HUGE_VAL, HUGE_VALF, and HUGE_VALL can be positive infinities in an implementation that supports infinities.

and in §7.12.1-5

If a floating result overflows and default rounding is in effect, then the function returns the value of the macro HUGE_VAL, HUGE_VALF, or HUGE_VALL according to the return type

Understanding xnanosleep (s)

Now we understand all essence of xstrtod(). From the explanations above, it is crystal-clear that xnanosleep(s) we've seen first actually means xnanosleep(HUGE_VALL).

xnanosleep()

According to the source code gnulib/lib/xnanosleep.c, xnanosleep(s) essentially does this:

struct timespec ts_sleep = dtotimespec (s);
nanosleep (&ts_sleep, NULL);

dtotimespec()

This function converts an argument of type double to an object of type struct timespec. Since it is very simple, let me cite the source code gnulib/lib/dtotimespec.c. All of the comments are added by me.

struct timespec
dtotimespec (double sec)
{
  if (! (TYPE_MINIMUM (time_t) < sec)) //underflow case
    return make_timespec (TYPE_MINIMUM (time_t), 0);
  else if (! (sec < 1.0 + TYPE_MAXIMUM (time_t))) //overflow case
    return make_timespec (TYPE_MAXIMUM (time_t), TIMESPEC_HZ - 1);
  else //normal case (looks complex but does nothing technical)
    {
      time_t s = sec;
      double frac = TIMESPEC_HZ * (sec - s);
      long ns = frac;
      ns += ns < frac;
      s += ns / TIMESPEC_HZ;
      ns %= TIMESPEC_HZ;

      if (ns < 0)
        {
          s--;
          ns += TIMESPEC_HZ;
        }

      return make_timespec (s, ns);
    }
}

Since time_t is defined as an integral type (see §7.27.1-3), it is natural we assume the maximum value of type time_t is smaller than HUGE_VAL (of type double), which means we enter the overflow case. (Actually this assumption is not needed since, in all cases, the procedure is essentially the same.)

make_timespec()

The last wall we have to climb up is make_timespec(). Very fortunately, it is so simple that citing the source code gnulib/lib/timespec.h is enough.

_GL_TIMESPEC_INLINE struct timespec
make_timespec (time_t s, long int ns)
{
  struct timespec r;
  r.tv_sec = s;
  r.tv_nsec = ns;
  return r;
}

Add new WebProxy() for the proxy setting , where you are creating a web request.

Example :-

  string url =  "Your URL";
  System.Net.WebRequest req = System.Net.WebRequest.Create(url);
  req.Proxy = new WebProxy();
  System.Net.WebResponse resp = req.GetResponse();

Where req.Proxy = new WebProxy() handle the proxy setting & helps the code to work fine.

Seems like there's a bug with applyFromArray right now that won't accept color, but this worked for me:

$objPHPExcel
    ->getActiveSheet()
    ->getStyle('A1')
    ->getFill()
    ->getStartColor()
    ->setRGB('FF0000');

If you would like the new data frame to have the same index and columns as an existing data frame, you can just multiply the existing data frame by zero:

df_zeros = df * 0

For those who use YAML configuration(application.yaml).

Note: this works only for Spring Boot 2.x.x

server:
  servlet:
    contextPath: /api

If you are still using Spring Boot 1.x

server:
  contextPath: /api

We all know that wait(), notify() and notifyAll() methods are used for inter-threaded communications. To get rid of missed signal and spurious wake up problems, waiting thread always waits on some conditions. e.g.-

boolean wasNotified = false;
while(!wasNotified) {
    wait();
}

Then notifying thread sets wasNotified variable to true and notify.

Every thread has their local cache so all the changes first get written there and then promoted to main memory gradually.

Had these methods not invoked within synchronized block, the wasNotified variable would not be flushed into main memory and would be there in thread's local cache so the waiting thread will keep waiting for the signal although it was reset by notifying thread.

To fix these types of problems, these methods are always invoked inside synchronized block which assures that when synchronized block starts then everything will be read from main memory and will be flushed into main memory before exiting the synchronized block.

synchronized(monitor) {
    boolean wasNotified = false;
    while(!wasNotified) {
        wait();
    }
}

Thanks, hope it clarifies.

your exists syntax is wrong and you should seperate DDL with go like below

if exists(select 1 from sys.views where name='tst' and type='v')
drop view tst;
go

create view tst
as
select * from test

you also can check existence test, with object_id like below

if object_id('tst','v') is not null
drop view tst;
go

create view tst
as
select * from test

In SQL 2016,you can use below syntax to drop

Drop view  if exists dbo.tst

From SQL2016 CU1,you can do below

create or alter view vwTest
as
 select 1 as col;
go

Here is how I would fix it, using a code snippet to give you a basic idea:

public class IFrame1 extends LoadableComponent<IFrame1> {

    private RemoteWebDriver driver;

    @FindBy(id = "iFrame1TextFieldTestInputControlID" ) public WebElement iFrame1TextFieldInput;
    @FindBy(id = "iFrame1TextFieldTestProcessButtonID" ) public WebElement copyButton;

    public IFrame1( RemoteWebDriver drv ) {
        super();
        this.driver = drv;
        this.driver.switchTo().defaultContent();
        waitTimer(1, 1000);
        this.driver.switchTo().frame("BodyFrame1");
        LOGGER.info("IFrame1 constructor...");
    }

    @Override
    protected void isLoaded() throws Error {        
        LOGGER.info("IFrame1.isLoaded()...");
        PageFactory.initElements( driver, this );
        try {
            assertTrue( "Page visible title is not yet available.", 
                    driver.findElementByCssSelector("body form#webDriverUnitiFrame1TestFormID h1")
                    .getText().equals("iFrame1 Test") );
        } catch ( NoSuchElementException e) {
            LOGGER.info("No such element." );
            assertTrue("No such element.", false);
        }
    }

    /**
     * Method: load
     * Overidden method from the LoadableComponent class.
     * @return  void
     * @throws  null
     */
    @Override
    protected void load() {
        LOGGER.info("IFrame1.load()...");
        Wait<WebDriver> wait = new FluentWait<WebDriver>( driver )
                .withTimeout(30, TimeUnit.SECONDS)
                .pollingEvery(5, TimeUnit.SECONDS)
                .ignoring( NoSuchElementException.class ) 
                .ignoring( StaleElementReferenceException.class ) ;
        wait.until( ExpectedConditions.presenceOfElementLocated( 
                By.cssSelector("body form#webDriverUnitiFrame1TestFormID h1") ) );
    }
....

I've needed this and after some research I came up with this (jQuery needed):

First, right after the <body> tag add this:

<div id="loading">
  <img id="loading-image" src="images/ajax-loader.gif" alt="Loading..." />
</div>

Then add the style class for the div and image to your CSS:

#loading {
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  position: fixed;
  display: block;
  opacity: 0.7;
  background-color: #fff;
  z-index: 99;
  text-align: center;
}

#loading-image {
  position: absolute;
  top: 100px;
  left: 240px;
  z-index: 100;
}

Then, add this javascript to your page (preferably at the end of your page, before your closing </body> tag, of course):

<script>
  $(window).load(function() {
    $('#loading').hide();
  });
</script>

Finally, adjust the position of the loading image and the background-colour of the loading div with the style class.

This is it, should work just fine. But of course you have to have an ajax-loader.gif somewhere. Freebies here. (Right-click > Save Image As...)

I think your problem is that the :after psuedo-element requires the content: property set inside it. You need to tell it to insert something. You could even just have it insert the image directly:

ul li:after {
    content: url('../images/small_triangle.png');
}

in css write

a.menu_links:hover{ cursor:pointer}

shuffle(names) is an in-place operation. Drop the assignment.

This function returns None and that's why you have the error:

TypeError: object of type 'NoneType' has no len()

Create an Ant file and tell Eclipse to build it. There are only two steps and each is easy with the step-by-step instructions below.

Step 1 Create a build.xml file and add to package explorer:

<?xml version="1.0" ?>
<!-- Configuration of the Ant build system to generate a Jar file --> 
<project name="TestMain" default="CreateJar">
  <target name="CreateJar" description="Create Jar file">
        <jar jarfile="Test.jar" basedir="." includes="*.class" />
  </target>
</project>

Eclipse should looks something like the screenshot below. Note the Ant icon on build.xml.

Step 2 Right-click on the root node in the project. - Select Properties - Select Builders - Select New - Select Ant Build - In the Main tab, complete the path to the build.xml file in the bin folder.

Check the Output

The Eclipse output window (named Console) should show the following after a build:

Buildfile: /home/<user>/src/Test/build.xml

CreateJar:
         [jar] Building jar: /home/<user>/src/Test/Test.jar
BUILD SUCCESSFUL
Total time: 152 milliseconds

EDIT: Some helpful comments by @yeoman and @betlista

@yeoman I think the correct include would be /.class, not *.class, as most people use packages and thus recursive search for class files makes more sense than flat inclusion

@betlista I would recomment to not to have build.xml in src folder

Another reason for "lost update" can be the next:

• If the static getDerivedStateFromProps is defined then it is rerun in every update process according to official documentation https://reactjs.org/docs/react-component.html#updating.
• so if that state value comes from props at the beginning it is overwrite in every update.

If it is the problem then U can avoid setting the state during update, you should check the state parameter value like this

static getDerivedStateFromProps(props: TimeCorrectionProps, state: TimeCorrectionState): TimeCorrectionState {
   return state ? state : {disable: false, timeCorrection: props.timeCorrection};
}

Another solution is add a initialized property to state, and set it up in the first time (if the state is initialized to non null value.)

There's no built-in JavaScript function to do this, but you can write your own fairly easily:

function pad(n) {
    return (n < 10) ? ("0" + n) : n;
}

EDIT:

Meanwhile there is a native JS function that does that. See String#padStart

console.log(String(5).padStart(2, '0'));

The LDF stand for 'Log database file' and it is the transaction log. It keeps a record of everything done to the database for rollback purposes, you can restore a database even you lost .msf file because it contain all control information plus transaction information .

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

Additional tip for ASP NET CORE:

Interface:

public interface IViewRenderer
{
  Task<string> RenderAsync<TModel>(Controller controller, string name, TModel model);
}

Implementation:

public class ViewRenderer : IViewRenderer
{
  private readonly IRazorViewEngine viewEngine;

  public ViewRenderer(IRazorViewEngine viewEngine) => this.viewEngine = viewEngine;

  public async Task<string> RenderAsync<TModel>(Controller controller, string name, TModel model)
  {
    ViewEngineResult viewEngineResult = this.viewEngine.FindView(controller.ControllerContext, name, false);

    if (!viewEngineResult.Success)
    {
      throw new InvalidOperationException(string.Format("Could not find view: {0}", name));
    }

    IView view = viewEngineResult.View;
    controller.ViewData.Model = model;

    await using var writer = new StringWriter();
    var viewContext = new ViewContext(
       controller.ControllerContext,
       view,
       controller.ViewData,
       controller.TempData,
       writer,
       new HtmlHelperOptions());

       await view.RenderAsync(viewContext);

       return writer.ToString();
  }
}

Registration in Startup.cs

...
 services.AddSingleton<IViewRenderer, ViewRenderer>();
...

And usage in controller:

public MyController: Controller
{
  private readonly IViewRenderer renderer;
  public MyController(IViewRendere renderer) => this.renderer = renderer;
  public async Task<IActionResult> MyViewTest
  {
    var view = await this.renderer.RenderAsync(this, "MyView", model);
    return new OkObjectResult(view);
  }
}

if you got an error

Execution failed for task ‘:app:fabricGenerateResourcesDebug’. Crashlytics Developer Tools error.

remove also this line:

apply plugin: 'io.fabric'

I've already commented it but I still think is a valid option, just test if in your environment is better one solution or the other. In my particular case, using source.ForEach(p => dest.Add(p)) performs better than the classic AddRange but I've not investigated why at the low level.

You can see an example code here: https://gist.github.com/mcliment/4690433

So the option would be:

var allProducts = new List<Product>(productCollection1.Count +
                                    productCollection2.Count +
                                    productCollection3.Count);

productCollection1.ForEach(p => allProducts.Add(p));
productCollection2.ForEach(p => allProducts.Add(p));
productCollection3.ForEach(p => allProducts.Add(p));

Test it to see if it works for you.

Disclaimer: I'm not advocating for this solution, I find Concat the most clear one. I just stated -in my discussion with Jon- that in my machine this case performs better than AddRange, but he says, with far more knowledge than I, that this does not make sense. There's the gist if you want to compare.

Another tip that would help a lot is that to set the current directory to a different drive one would have to use %~d0 first, then cd %~dp0. This will change the directory to the batch file's drive, then change to its folder.

Alternatively, for #oneLinerLovers, as @Omni pointed out in the comments cd /d %~dp0 will change both the drive and directory :)

Hope this helps someone.

Means Not a Number. It is a common representation for an impossible numeric value in many programming languages.

You can use .concat method to create copy of your array with new data:

this.setState({ myArray: this.state.myArray.concat('new value') })

But beware of special behaviour of .concat method when passing arrays - [1, 2].concat(['foo', 3], 'bar') will result in [1, 2, 'foo', 3, 'bar'].

if (   ($name eq "tom" and $password eq "123!")
    or ($name eq "frank" and $password eq "321!")) {

    print "You have gained access.";
}
else {
    print "Access denied!";
}

As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )

The querystring (get) parameters included in your url probably will not do anything.

Try this:

string url = "http://myserver/method";    
string content = "param1=1&param2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

        K = 2
    M = int((9 * (K + N)) / 275.0 + 0.98)
    if N < 32:
        M = 1
    D = N - int((275 * M) / 9.0) + K * int((M + 9) / 12.0) + 30
    return Y, M, D

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

String courseID = "Comp-101";
List<String> scores = new ArrayList<String> ();
scores.add("100");
scores.add("90");
scores.add("80");
scores.add("97");

Map<String, ArrayList<String>> myMap = new HashMap<String, ArrayList<String>>();
myMap.put(courseID, scores);

Hope this helps!

To count the Hbase table record count on a proper YARN cluster you have to set the map reduce job queue name as well:

hbase org.apache.hadoop.hbase.mapreduce.RowCounter -Dmapreduce.job.queuename= < Your Q Name which you have SUBMIT access>
 < TABLE_NAME>

You can use the Like operator with a wildcard to determine whether a given substring exists in a string, for example:

If cell.Value Like "*Word1*" Then
'...
ElseIf cell.Value Like "*Word2*" Then
'...
End If

In this example the * character in "*Word1*" is a wildcard character which matches zero or more characters.

NOTE: The Like operator is case-sensitive, so "Word1" Like "word1" is false, more information can be found on this MSDN page.

Need not to use HTML properties, let's focus on java xD I had the same problem, i found the way to do it in java:

String text="Hide post";
TextView tvHide=(TextView)findViewById(R.id.text);
SpannableString spanString = new SpannableString(text);
spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
tvHide.setText(spanString );

In my case: I forgot to activate virtualenv

I installed "pip install example" in the wrong virtualenv

From your original code it looks like what you want is to check if the list was empty:

var getResult= keyValueList.SingleOrDefault();
if (keyValueList.Count == 0)
{
   /* default */
}
else
{
}

Make sure not to create symlinks (ln -s source dest) from inside of Git Bash for Windows.

It does NOT make symlinks, but does a DEEP copy of the source to the dest

I experienced same behavior as OP on a MINGW64 terminal from Git Bash for Windows (version 2.16.2) to realize that my 'edited' changes actually were in the original directory, and my git bash commands were from within a deep copy that had remained unchanged.

I will point out that in the article linked in the top rated answer The Curse and Blessings of Dynamic SQL the author states that the answer is not to use dynamic SQL. Scroll almost to the end to see this.

From the article: "The correct method is to unpack the list into a table with a user-defined function or a stored procedure."

Of course, once the list is in a table you can use a join. I could not comment directly on the top rated answer, so I just added this comment.

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

The other solutions posted here didn't work for me, because:

• i just needed parameters from a file for a normal script
• import * didn't work for me, as i need a way to override them by choosing another file
• Just a file with a dict wasn't fine, as I needed comments in it.

So I ended up using Configparser and globals().update()

Test file:

#File parametertest.cfg:
[Settings]
#Comments are no Problem
test= True
bla= False    #Here neither

#that neither

And that's my demo script:

import ConfigParser

cfg = ConfigParser.RawConfigParser()
cfg.read('parametertest.cfg')       # Read file

#print cfg.getboolean('Settings','bla') # Manual Way to acess them

par=dict(cfg.items("Settings"))
for p in par:
    par[p]=par[p].split("#",1)[0].strip() # To get rid of inline comments

globals().update(par)  #Make them availible globally

print bla

It's just for a file with one section now, but that will be easy to adopt.

Hope it will be helpful for someone :)

There are three basic ways to do this depending on what you have done with the changes to the file A. If you have not yet added the changes to the index or committed them, then you just want to use the checkout command - this will change the state of the working copy to match the repository:

git checkout A

If you added it to the index already, use reset:

git reset A

If you had committed it, then you use the revert command:

# the -n means, do not commit the revert yet
git revert -n <sha1>
# now make sure we are just going to commit the revert to A
git reset B
git commit

If on the other hand, you had committed it, but the commit involved rather a lot of files that you do not also want to revert, then the above method might involve a lot of "reset B" commands. In this case, you might like to use this method:

# revert, but do not commit yet
git revert -n <sha1>
# clean all the changes from the index
git reset
# now just add A
git add A
git commit

Another method again, requires the use of the rebase -i command. This one can be useful if you have more than one commit to edit:

# use rebase -i to cherry pick the commit you want to edit
# specify the sha1 of the commit before the one you want to edit
# you get an editor with a file and a bunch of lines starting with "pick"
# change the one(s) you want to edit to "edit" and then save the file
git rebase -i <sha1>
# now you enter a loop, for each commit you set as "edit", you get to basically redo that commit from scratch
# assume we just picked the one commit with the erroneous A commit
git reset A
git commit --amend
# go back to the start of the loop
git rebase --continue

@GET
@Path("/friends")
@Produces(MediaType.APPLICATION_JSON)
public String getFriends() {

    // here you can return any bean also it will automatically convert into json 
    return "{'friends': ['Michael', 'Tom', 'Daniel', 'John', 'Nick']}";
}

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

Try this in Android DataBinding

FragmentMainBinding binding;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        binding = DataBindingUtil.inflate(inflater, R.layout.fragment_main, container, false);
        View rootView = binding.getRoot();
        initInstances(savedInstanceState);
        return rootView;
}

Thread.sleep() could work in most cases, but usually if you're waiting, you are actually waiting for a particular condition or state to occur. Thread.sleep() does not guarantee that whatever you're waiting for has actually happened.

If you are waiting on a rest request for example maybe it usually return in 5 seconds, but if you set your sleep for 5 seconds the day your request comes back in 10 seconds your test is going to fail.

To remedy this JayWay has a great utility called Awatility which is perfect for ensuring that a specific condition occurs before you move on.

It has a nice fluent api as well

await().until(() -> 
{
    return yourConditionIsMet();
});

Angular 2 and Angular 4 

In a ngFor loop it must be look like this:

<div class="column" *ngFor="let u of events ">
                <div class="thumb">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>

You may try adding an additional argument of type HttpServletRequest to the getUrlValue() method:

@RequestMapping(value ="/",produces = "application/json")
public String getURLValue(HttpServletRequest request){
    String test = request.getRequestURI();
    return test;
}

First navigate to your Java/jre/bin folder in cmd cd c:\Program Files (x86)\Java\jre7\bin

Then use : [change debug.keystore path to the correct location on your system] install openssl (for windows 32 or 64 as per your needs at c:\openssl )

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\vibhor\.android\debug.keystore" | "c:\openssl\bin\openssl.exe" sha1 -binary | "c:\openssl\bin\openssl.exe" base64

So the whole command goes like this : [prompts to enter keystore password on execution ]

c:\Program Files (x86)\Java\jre7\bin>keytool -exportcert -alias androiddebugkey
-keystore "C:\Users\vibhor\.android\debug.keystore" | "c:\openssl\bin\openssl.ex
e" sha1 -binary | "c:\openssl\bin\openssl.exe" base64
Enter keystore password:

If you are getting this in a C# projet, check if you are running in 64-bit or 32-bit mode with the following code:

        if (IntPtr.Size == 4)
        {
            Console.WriteLine("This is 32-Bit!");
        }
        else if (IntPtr.Size == 8)
        {
            Console.WriteLine("This is 64 Bit!");
        }

If you find that you are running in 64-Bit mode, you may want to try switching to 32-Bit (or vice versa). You can follow this guide to force your application to run as 64 or 32 bit (X64 and X86 respectively). You have to make sure that Platform Target in your project properties is not set to Any CPU and that it is explicitley set.

Switching that option from Any CPU to X86 resolved my error and I was able to connect to the Oracle provider.

IMHO, the most elegant way is using the Java API for JSON Processing (JSON-P), one of the JavaEE standards that conforms to the JSR 374.

try(StringReader sr = new StringReader(jsonStrn)) {
    Json.createReader(sr).readObject();
} catch(JsonParsingException e) {
    System.out.println("The given string is not a valid json");
    e.printStackTrace();
}

Using Maven, add the dependency on JSON-P:

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>
    <version>1.1.4</version>
</dependency>

Visit the JSON-P official page for more informations.

You may be forgetting something. Before #include <iostream>, write #include <stdafx.h> and maybe that will help. Then, when you are done writing, click test, than click output from build, then when it is done processing/compiling, press Ctrl+F5 to open the Command Prompt and it should have the output and "press any key to continue."

Depends on the extension. If it's .html, you can use <? to start and ?> to end a comment. That's really the only alternative that I can think of. http://jsfiddle.net/SuEAW/

Just 2 simple steps to solve your issue

First of all check AppendDataBoundItems property and make it assign false

Secondly clear all the items using property .clear()

{
ddl1.Items.Clear();
ddl1.datasource = sql1;
ddl1.DataBind();
}

This one I implemented for my website , If some one got more no's of menu item and longer search bar can use this

I love the Try pattern. It's a tidy pattern.

if (double.TryParse(name, out var result))
{
    // handle success
}
else
{
    // handle error
}

But, it's challenging with async. That doesn't mean we don't have real options. Here are the three core approaches you can consider for async methods in a quasi-version of the Try pattern.

Approach 1 - output a structure

This looks most like a sync Try method only returning a tuple instead of a bool with an out parameter, which we all know is not permitted in C#.

var result = await DoAsync(name);
if (result.Success)
{
    // handle success
}
else
{
    // handle error
}

With a method that returns true of false and never throws an exception.

Remember, throwing an exception in a Try method breaks the whole purpose of the pattern.

async Task<(bool Success, StorageFile File, Exception exception)> DoAsync(string fileName)
{
    try
    {
        var folder = ApplicationData.Current.LocalCacheFolder;
        return (true, await folder.GetFileAsync(fileName), null);
    }
    catch (Exception exception)
    {
        return (false, null, exception);
    }
}

Approach 2 - pass in callback methods

We can use anonymous methods to set external variables. It's clever syntax, though slightly complicated. In small doses, it's fine.

var file = default(StorageFile);
var exception = default(Exception);
if (await DoAsync(name, x => file = x, x => exception = x))
{
    // handle success
}
else
{
    // handle failure
}

The method obeys the basics of the Try pattern but sets out parameters to passed in callback methods. It's done like this.

async Task<bool> DoAsync(string fileName, Action<StorageFile> file, Action<Exception> error)
{
    try
    {
        var folder = ApplicationData.Current.LocalCacheFolder;
        file?.Invoke(await folder.GetFileAsync(fileName));
        return true;
    }
    catch (Exception exception)
    {
        error?.Invoke(exception);
        return false;
    }
}

There's a question in my mind about performance here. But, the C# compiler is so freaking smart, that I think you're safe choosing this option, almost for sure.

Approach 3 - use ContinueWith

What if you just use the TPL as designed? No tuples. The idea here is that we use exceptions to redirect ContinueWith to two different paths.

await DoAsync(name).ContinueWith(task =>
{
    if (task.Exception != null)
    {
        // handle fail
    }
    if (task.Result is StorageFile sf)
    {
        // handle success
    }
});

With a method that throws an exception when there is any kind of failure. That's different than returning a boolean. It's a way to communicate with the TPL.

async Task<StorageFile> DoAsync(string fileName)
{
    var folder = ApplicationData.Current.LocalCacheFolder;
    return await folder.GetFileAsync(fileName);
}

In the code above, if the file is not found, an exception is thrown. This will invoke the failure ContinueWith that will handle Task.Exception in its logic block. Neat, huh?

Listen, there's a reason we love the Try pattern. It's fundamentally so neat and readable and, as a result, maintainable. As you choose your approach, watchdog for readability. Remember the next developer who in 6 months and doesn't have you to answer clarifying questions. Your code can be the only documentation a developer will ever have.

Best of luck.

It is easy. C++11 provides an easy way to sum up elements of a vector.

sum = 0; 
vector<int> vec = {1,2,3,4,5,....}
for(auto i:vec) 
   sum+=i;
cout<<" The sum is :: "<<sum<<endl; 

UPDATE a
SET a.column1 = b.column2
FROM myTable a 
INNER JOIN myTable b
on a.myID = b.myID

in order for both "a" and "b" to work, both aliases must be defined

Negative numbers mean that you count from the right instead of the left. So, list[-1] refers to the last element, list[-2] is the second-last, and so on.

Use jQuery:

$.ajax({ url: 'your-url', success: function(data) { alert(data); } });

This data is your HTML.

Without jQuery (just JavaScript):

function makeHttpObject() {
  try {return new XMLHttpRequest();}
  catch (error) {}
  try {return new ActiveXObject("Msxml2.XMLHTTP");}
  catch (error) {}
  try {return new ActiveXObject("Microsoft.XMLHTTP");}
  catch (error) {}

  throw new Error("Could not create HTTP request object.");
}

var request = makeHttpObject();
request.open("GET", "your_url", true);
request.send(null);
request.onreadystatechange = function() {
  if (request.readyState == 4)
    alert(request.responseText);
};

Assume you have one table with name 'table1'. It contain one column 'col1' with varchar type. Query to crate table is give below

CREATE TABLE `table1` (
    `col1` VARCHAR(50) NULL DEFAULT NULL
)

Now if you want to insert number from 1 to 50 in that table then use following stored procedure

DELIMITER $$  
CREATE PROCEDURE ABC()

   BEGIN
      DECLARE a INT Default 1 ;
      simple_loop: LOOP         
         insert into table1 values(a);
         SET a=a+1;
         IF a=51 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

To call that stored procedure use

CALL `ABC`()

How to fix app:mergeDebugResources in Android Studio (Resource path could not resolved / R.id is not accessible)

• Go to the project folder from file explorer.
• Delete(before delete Backup all files) .idea folder
• If there are any .gradle folder do the 2nd step to the .gradle folder too.
• If the Exception is referring any 3rd party library/jar file delete that also(keep a backup to add later)
• Open the project again from Android studio as "Open an existing android studio project"
• On right side gradle tab click "Refresh all Gradle projects".This will create the gradel project dependancies
• Now add again 3rd party libraries to the same previous folder structure

This should resolve your Gradle issue.. good luck.

In JavaScript you can encode single quotes as "\x27" and double quotes as "\x22". Therefore, with this method you can, once you're inside the (double or single) quotes of a JavaScript string literal, use the \x27 \x22 with impunity without fear of any embedded quotes "breaking out" of your string.

\xXX is for chars < 127, and \uXXXX for Unicode, so armed with this knowledge you can create a robust JSEncode function for all characters that are out of the usual whitelist.

For example,

<a href="#" onclick="SelectSurveyItem('<% JSEncode(itemid) %>', '<% JSEncode(itemname) %>'); return false;">Select</a>

I found this snippet here. The idea is to go up the DOM node hierarchy until a __vue__ property is found.

function getVueFromElement(el) {
  while (el) {
    if (el.__vue__) {
      return el.__vue__
    } else {
      el = el.parentNode
    }
  }
}

If you look at the standard libraries the pattern generally is my_function, but every person does seem to have their own way :-/

A list is a chain of spaces that can be indexed by (0, 1, 2 .... etc). So if players was a list, players[0] or players[1] would have worked. If players is a dictionary, players["name"] would have worked.

One alternative would be to parse with yq (https://github.com/kislyuk/yq) like so:

cat pom.xml | xq -r '.project.version'

Notice the executable is xq not yq

To get xq, install yq like so pip install yq

Look at the google gson library. It provides a rich api for dealing with this and is very straightforward to use.

Here is a simple work around for white space between the '=' sign and the data, in the config file. Assign to the istringstream from the location after the '=' sign and when reading from it, any leading white space is ignored.

Note: while using an istringstream in a loop, make sure you call clear() before assigning a new string to it.

//config.txt
//Input name = image1.png
//Num. of rows = 100
//Num. of cols = 150

std::string ipName;
int nR, nC;

std::ifstream fin("config.txt");
std::string line;
std::istringstream sin;

while (std::getline(fin, line)) {
 sin.str(line.substr(line.find("=")+1));
 if (line.find("Input name") != std::string::npos) {
  std::cout<<"Input name "<<sin.str()<<std::endl;
  sin >> ipName;
 }
 else if (line.find("Num. of rows") != std::string::npos) {
  sin >> nR;
 }
 else if (line.find("Num. of cols") != std::string::npos) {
  sin >> nC;
 }
 sin.clear();
}

I needed the same and this solution worked the most simple and straightforward way:

http://www.farinspace.com/jquery-scrollable-table-plugin/

I just give an id to the table I want to scroll and put one line in Javascript. That's it!

By the way, first I also thought I want to use a scrollable div, but it is not necessary at all. You can use a div and put it into it, but this solution does just what we need: scrolls the table.

If you have problems like that, first of all your TC folder put in to the C:..drive. after completing installation open turbo c blue screen. there is a OPTIONS > Directories ..in that you can see for option to set up path..

1. include directories..you can set path there now.. C:\TC\INCUDE
2. libraries Directories..you can set path there...C:\TC\LIB
3. if you want to store your output in BIN then you can set..C:\TC\BIN..otherwise you can set another path where you want to store your output..

Finally you can give OK and finished processes.. It will now work properly

just use UPDATE query without condition like this

 UPDATE tablename SET online_status=0;

Another solution to the issue above is to set each string to a variable, call the function with variables denoted by a literal dollar sign \$. Then in the function use eval to read the variable and output as expected.

#!/usr/bin/ksh

myFunction()
{
  eval string1="$1"
  eval string2="$2"
  eval string3="$3"

  echo "string1 = ${string1}"
  echo "string2 = ${string2}"
  echo "string3 = ${string3}"
}

var1="firstString"
var2="second string with spaces"
var3="thirdString"

myFunction "\${var1}" "\${var2}" "\${var3}"

exit 0

Output is then:

    string1 = firstString
    string2 = second string with spaces
    string3 = thirdString

In trying to solve a similar problem to this, I was running into the issue of UNIX thinking my variables were space delimeted. I was trying to pass a pipe delimited string to a function using awk to set a series of variables later used to create a report. I initially tried the solution posted by ghostdog74 but could not get it to work as not all of my parameters were being passed in quotes. After adding double-quotes to each parameter it then began to function as expected.

Below is the before state of my code and fully functioning after state.

Before - Non Functioning Code

#!/usr/bin/ksh

#*******************************************************************************
# Setup Function To Extract Each Field For The Error Report
#*******************************************************************************
getField(){
  detailedString="$1"
  fieldNumber=$2

  # Retrieves Column ${fieldNumber} From The Pipe Delimited ${detailedString} 
  #   And Strips Leading And Trailing Spaces
  echo ${detailedString} | awk -F '|' -v VAR=${fieldNumber} '{ print $VAR }' | sed 's/^[ \t]*//;s/[ \t]*$//'
}

while read LINE
do
  var1="$LINE"

  # Below Does Not Work Since There Are Not Quotes Around The 3
  iputId=$(getField "${var1}" 3)
done<${someFile}

exit 0

After - Functioning Code

#!/usr/bin/ksh

#*******************************************************************************
# Setup Function To Extract Each Field For The Report
#*******************************************************************************
getField(){
  detailedString="$1"
  fieldNumber=$2

  # Retrieves Column ${fieldNumber} From The Pipe Delimited ${detailedString} 
  #   And Strips Leading And Trailing Spaces
  echo ${detailedString} | awk -F '|' -v VAR=${fieldNumber} '{ print $VAR }' | sed 's/^[ \t]*//;s/[ \t]*$//'
}

while read LINE
do
  var1="$LINE"

  # Below Now Works As There Are Quotes Around The 3
  iputId=$(getField "${var1}" "3")
done<${someFile}

exit 0

this is working for me:

<td>
  <div class="avoid">
    Cell content.
  </div>
</td>
...
<style type="text/css">
  .avoid {
    page-break-inside: avoid !important;
    margin: 4px 0 4px 0;  /* to keep the page break from cutting too close to the text in the div */
  }
</style>

From this thread: avoid page break inside row of table

Escaping parameters like that is usually source of frustration and feels a lot like a time wasted. I see you're on v2 so I would suggest using a technique that Joel "Jaykul" Bennet blogged about a while ago.

Long story short: you just wrap your string with @' ... '@ :

Start-Process \\server\toto.exe @'
-batch=B -param="sort1;parmtxt='Security ID=1234'"
'@

(Mind that I assumed which quotes are needed, and which things you were attempting to escape.) If you want to work with the output, you may want to add the -NoNewWindow switch.

BTW: this was so important issue that since v3 you can use --% to stop the PowerShell parser from doing anything with your parameters:

\\server\toto.exe --% -batch=b -param="sort1;paramtxt='Security ID=1234'"

... should work fine there (with the same assumption).

I am not familiar with this plugin, but we quite successfully use Bitbucket and Jenkins together, however we poll for changes instead of having them pushed from BitBucket (due to the fact our build server is hidden behind a company firewall). This approach may work for you if you are still having problems with the current approach.

This document on Setting up SSH for Git & Mercurial on Linux covers the details of what you need to do to be able to communicate between your build server and Bitbucket over SSH. Once this is done, with the Git Plugin installed, go to your build configuration and select 'Git' under Source Code Management, and enter the ssh URL of your repository as the repository URL. Finally, in the Build Triggers section, select Poll SCM and set the poll frequency to whatever you require.

The documentation for START_STICKY and START_NOT_STICKY is quite straightforward.

START_STICKY:

If this service's process is killed while it is started (after returning from onStartCommand(Intent, int, int)), then leave it in the started state but don't retain this delivered intent. Later the system will try to re-create the service. Because it is in the started state, it will guarantee to call onStartCommand(Intent, int, int) after creating the new service instance; if there are not any pending start commands to be delivered to the service, it will be called with a null intent object, so you must take care to check for this.

This mode makes sense for things that will be explicitly started and stopped to run for arbitrary periods of time, such as a service performing background music playback.

Example: Local Service Sample

START_NOT_STICKY:

If this service's process is killed while it is started (after returning from onStartCommand(Intent, int, int)), and there are no new start intents to deliver to it, then take the service out of the started state and don't recreate until a future explicit call to Context.startService(Intent). The service will not receive a onStartCommand(Intent, int, int) call with a null Intent because it will not be re-started if there are no pending Intents to deliver.

This mode makes sense for things that want to do some work as a result of being started, but can be stopped when under memory pressure and will explicit start themselves again later to do more work. An example of such a service would be one that polls for data from a server: it could schedule an alarm to poll every N minutes by having the alarm start its service. When its onStartCommand(Intent, int, int) is called from the alarm, it schedules a new alarm for N minutes later, and spawns a thread to do its networking. If its process is killed while doing that check, the service will not be restarted until the alarm goes off.

Example: ServiceStartArguments.java

My issue was really difficult to track down. In the end, the problem was occurring when the web page had missing images. The src was missing a Url. This was happening on an MVC 5 Web Controller. To fix the issue, I included transparent images when no real image is available.

<img alt="" class="logo" src="">

If you can live with limited parallel capablilities, the following solution will work:

private static <T> Stream<T> nonEmptyStream(
    Stream<T> stream, Supplier<RuntimeException> e) {

    Spliterator<T> it=stream.spliterator();
    return StreamSupport.stream(new Spliterator<T>() {
        boolean seen;
        public boolean tryAdvance(Consumer<? super T> action) {
            boolean r=it.tryAdvance(action);
            if(!seen && !r) throw e.get();
            seen=true;
            return r;
        }
        public Spliterator<T> trySplit() { return null; }
        public long estimateSize() { return it.estimateSize(); }
        public int characteristics() { return it.characteristics(); }
    }, false);
}

Here is some example code using it:

List<String> l=Arrays.asList("hello", "world");
nonEmptyStream(l.stream(), ()->new RuntimeException("No strings available"))
  .forEach(System.out::println);
nonEmptyStream(l.stream().filter(s->s.startsWith("x")),
               ()->new RuntimeException("No strings available"))
  .forEach(System.out::println);

The problem with (efficient) parallel execution is that supporting splitting of the Spliterator requires a thread-safe way to notice whether either of the fragments has seen any value in a thread-safe manner. Then the last of the fragments executing tryAdvance has to realize that it is the last one (and it also couldn’t advance) to throw the appropriate exception. So I didn’t add support for splitting here.

If istream fails to insert, it will set the fail bit.

int i = 0;
std::cin >> i; // type a and press enter
if (std::cin.fail())
{
    std::cout << "I failed, try again ..." << std::endl
    std::cin.clear(); // reset the failed state
}

You can set this up in a do-while loop to get the correct type (int in this case) propertly inserted.

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

If you need to know the amount of every element in array besides existing of that element you may use

my %bad_param_lookup;
@bad_param_lookup{ @bad_params } = ( 1 ) x @bad_params;
%bad_param_lookup = map { $_ => $bad_param_lookup{$_}++} @bad_params;

and then for every $i that is in @bad_params, $bad_param_lookup{$i} contains amount of $i in @bad_params

Convert the Special characters to apostrophe,

Data  <- gsub("[^0-9A-Za-z///' ]","'" , Data ,ignore.case = TRUE)

Below code it to remove extra ''' apostrophe

Data <- gsub("''","" , Data ,ignore.case = TRUE)

Use gsub(..) function for replacing the special character with apostrophe

They both take a function from the type of the optional to something.

map() applies the function "as is" on the optional you have:

if (optional.isEmpty()) return Optional.empty();
else return Optional.of(f(optional.get()));

What happens if your function is a function from T -> Optional<U>?
Your result is now an Optional<Optional<U>>!

That's what flatMap() is about: if your function already returns an Optional, flatMap() is a bit smarter and doesn't double wrap it, returning Optional<U>.

It's the composition of two functional idioms: map and flatten.

A different approach:

1. instead of a select make it an edit box, disabled so noone can enter anything manually or change contents after selection
2. another hidden edit to contain an id of a selected option (explained below)
3. make a button [..] and script it to show that div below
4. make a hidden div with absolute position under or near the edit box
5. make that div to contain a select with style size="6" (to show 6 options and a scrollbar rather than a drop-down list) and a button "select" and maybe "cancel"
6. Do not style width so the whole thing will assume width of the widest option or the button plus maybe some padding of your choice
7. script the "select" button to copy id of the selected option to the hidden edit box and it's value to the visible one, also to hide the div again.

4 simple javascript commands total.

Note: imp is deprecated since Python 3.4 in favor of importlib

As mentioned the imp module provides you loading functions:

imp.load_source(name, path)
imp.load_compiled(name, path)

I've used these before to perform something similar.

In my case I defined a specific class with defined methods that were required. Once I loaded the module I would check if the class was in the module, and then create an instance of that class, something like this:

import imp
import os

def load_from_file(filepath):
    class_inst = None
    expected_class = 'MyClass'

    mod_name,file_ext = os.path.splitext(os.path.split(filepath)[-1])

    if file_ext.lower() == '.py':
        py_mod = imp.load_source(mod_name, filepath)

    elif file_ext.lower() == '.pyc':
        py_mod = imp.load_compiled(mod_name, filepath)

    if hasattr(py_mod, expected_class):
        class_inst = getattr(py_mod, expected_class)()

    return class_inst

Maybe:

crimefile = open(fileName, 'r')
yourResult = [line.split(',') for line in crimefile.readlines()]

If your calling code is referencing the System.Windows.Forms assembly, you may consider a radically different approach. My strategy is to use the functions already provided by the framework to accomplish this in very few lines of code and without having to loop through columns and rows. What the code below does is programmatically create a DataGridView on the fly and set the DataGridView.DataSource to the DataTable. Next, I programmatically select all the cells (including the header) in the DataGridView and call DataGridView.GetClipboardContent(), placing the results into the Windows Clipboard. Then, I 'paste' the contents of the clipboard into a call to File.WriteAllText(), making sure to specify the formatting of the 'paste' as TextDataFormat.CommaSeparatedValue.

Here is the code:

public static void DataTableToCSV(DataTable Table, string Filename)
{
    using(DataGridView dataGrid = new DataGridView())
    {
        // Save the current state of the clipboard so we can restore it after we are done
        IDataObject objectSave = Clipboard.GetDataObject();

        // Set the DataSource
        dataGrid.DataSource = Table;
        // Choose whether to write header. Use EnableWithoutHeaderText instead to omit header.
        dataGrid.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableAlwaysIncludeHeaderText;
        // Select all the cells
        dataGrid.SelectAll();
        // Copy (set clipboard)
        Clipboard.SetDataObject(dataGrid.GetClipboardContent());
        // Paste (get the clipboard and serialize it to a file)
        File.WriteAllText(Filename,Clipboard.GetText(TextDataFormat.CommaSeparatedValue));              

        // Restore the current state of the clipboard so the effect is seamless
        if(objectSave != null) // If we try to set the Clipboard to an object that is null, it will throw...
        {
            Clipboard.SetDataObject(objectSave);
        }
    }
}

Notice I also make sure to preserve the contents of the clipboard before I begin, and restore it once I'm done, so the user does not get a bunch of unexpected garbage next time the user tries to paste. The main caveats to this approach is 1) Your class has to reference System.Windows.Forms, which may not be the case in a data abstraction layer, 2) Your assembly will have to be targeted for .NET 4.5 framework, as DataGridView does not exist in 4.0, and 3) The method will fail if the clipboard is being used by another process.

Anyways, this approach may not be right for your situation, but it is interesting none the less, and can be another tool in your toolbox.

For Intellij go to View > Tool Windows > Gradle > Refresh All Projects (the blue circular arrows at the top of the Gradle window.

    D:\Java\jdk1.5.0_10\bin\keytool -import -file "D:\Certificates\SDS services\Dev\dev-sdsservices-was8.infavig.com.cer" -keystore "D:\Java\jdk1.5.0_10\jre\lib\security\cacerts" -alias "sds certificate"

Try the to_date function.

Try getting the input stream from this you can then get the text data as so:-

    URL url;
    HttpURLConnection urlConnection = null;
    try {
        url = new URL("http://www.mysite.se/index.asp?data=99");

        urlConnection = (HttpURLConnection) url
                .openConnection();

        InputStream in = urlConnection.getInputStream();

        InputStreamReader isw = new InputStreamReader(in);

        int data = isw.read();
        while (data != -1) {
            char current = (char) data;
            data = isw.read();
            System.out.print(current);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }    
    }

You can probably use other inputstream readers such as buffered reader also.

The problem is that when you open the connection - it does not 'pull' any data.

Another suggestion is using flexbox instead of tables altogether. This is a "modern browser" thing of course, but come on, it's 2016 ;)

At least this might be an alternative solution for those looking for an answer to this nowadays, since the original post was from 2010.

Here's a great guide: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

    row 2 - cell 1 (spans 3 columns)_x000D_
  </div>_x000D_
</div>

you use the scrollTop attribute

var position = document.getElementById('id').scrollTop;

I doubt I'd use it in a mission-critical system, but Derby has always been very interesting to me.

Actually you need two div's for vertical centering. The div containing the content must have a width and height.

#container {_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  margin-top: -200px;_x000D_
  /* half of #content height*/_x000D_
  left: 0;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
#content {_x000D_
  width: 624px;_x000D_
  margin-left: auto;_x000D_
  margin-right: auto;_x000D_
  height: 395px;_x000D_
  border: 1px solid #000000;_x000D_
}

<div id="container">_x000D_
  <div id="content">_x000D_
    <h1>Centered div</h1>_x000D_
  </div>_x000D_
</div>

Here is the result

StringBuilder sb = new StringBuilder(name);
sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));  
return sb.toString();

if you forget your admin then you need to create new user by using

python manage.py createsuperuser <username>

and for password there is CLI command changepassword for django to change user password

python manage.py changepassword <username>

OR

django-admin changepassword <username>

OR Run this code in Django env

from django.contrib.auth.models import User
u = User.objects.get(username='john')
u.set_password('new password')
u.save()

You could create Util class:

public final class CollectionHelpers {
    public static <T> boolean addNullSafe(List<T> list, T element) {
        if (list == null || element == null) {
            return false;
        }

        return list.add(element);
    }
}

And then use it:

Element element = getElementFromSomeWhere(someParameter);
List<Element> arrayList = new ArrayList<>();
CollectionHelpers.addNullSafe(list, element);

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("listfile.txt")
Dim inFile: Set inFile = obj.OpenTextFile("listfile.txt")

' read file
data = inFile.ReadAll

The Problem to push mostly is because of the size of the files that need to be pushed. I was trying to push some libraries of just size 2 mb, then too the push was giving error of RPC with result 7. The line is of 4 mbps and is working fine. Some subsequent tries to the push got me success. If such error comes, wait for few minutes and keep on trying.

I also found out that there are some RPC failures if the github is down or is getting unstable network at their side.

So keeping up trying after some intervals is the only option!

I used

echo "Start of Body" && uuencode log.cfg readme.txt | mail -s "subject" "[email protected]" 

and this worked well for me....

Ok, The Windows 10 BatchFile is done works just like I had hoped. First press the windows key and R. Type mmc and Enter. In File Add SnapIn>Got to a specific Website and add it to the list. Press OK in the tab, and on the left side console root menu double click your site. Once it opens Add it to favourites. That should place it in C:\Users\user\AppData\Roaming\Microsoft\StartMenu\Programs\Windows Administrative Tools. I made a shortcut of this to a folder on the desktop. Right click the Shortcut and view the properties. In the Shortcut tab of the Properties click advanced and check the Run as Administrator. The Start in Location is also on the Shortcuts Tab you can add that to your batch file if you need. The Batch I made is as follows

@echo off
title Manage SiteEnviro
color 0a
:Clock
cls
echo Date:%date% Time:%time%
pause
cls
c:\WINDOWS\System32\netstat
c:\WINDOWS\System32\netstat -an
goto Greeting

:Greeting
cls
echo Open ShellSite
pause
cls
goto Manage SiteEnviro

:Manage SiteEnviro
"C:\Users\user\AppData\Roaming\Microsoft\Start Menu\Programs\Administrative Tools\YourCustomSavedMMC.msc"

You need to make a shortcut when you save this as a bat file and in the properties>shortcuts>advanced enable administrator access, can also set a keybind there and change the icon if you like. I probably did not need :Clock. The netstat commands can change to setting a hosted network or anything you want including nothing. Can Canscade websites in 1 mmc console and have more than 1 favourite added into the batch file.

Summary: the C++ Standard could specify a notation and behaviour for "virtual constructor"s that's reasonably intuitive and not too hard for compilers to support, but why make a Standard change for this specifically when the functionality can already be cleanly implemented using create() / clone() (see below)? It's not nearly as useful as many other language proposal in the pipeline.

Discussion

Let's postulate a "virtual constructor" mechanism:

Base* p = new Derived(...);
Base* p2 = new p->Base();  // possible syntax???

In the above, the first line constructs a Derived object, so *p's virtual dispatch table can reasonably supply a "virtual constructor" for use in the second line. (Dozens of answers on this page stating "the object doesn't yet exist so virtual construction is impossible" are unnecessarily myopically focused on the to-be-constructed object.)

The second line postulates the notation new p->Base() to request dynamic allocation and default construction of another Derived object.

Notes:

• the compiler must orchestrate memory allocation before calling the constructor - constructors normally support automatic (informally "stack") allocation, static (for global/namespace scope and class-/function-static objects), and dynamic (informally "heap") when new is used

  • the size of object to be constructed by p->Base() can't generally be known at compile-time, so dynamic allocation is the only approach that makes sense

    • it is possible to allocate runtime-specified amounts of memory on the stack - e.g. GCC's variable-length array extension, alloca() - but leads to significant inefficiencies and complexities (e.g. here and here respectively)

• for dynamic allocation it must return a pointer so memory can be deleted later.

• the postulated notation explicitly lists new to emphasise dynamic allocation and the pointer result type.

The compiler would need to:

• find out how much memory Derived needed, either by calling an implicit virtual sizeof function or having such information available via RTTI
• call operator new(size_t) to allocate memory
• invoke Derived() with placement new.

OR

• create an extra vtable entry for a function that combines dynamic allocation and construction

So - it doesn't seem insurmountable to specify and implement virtual constructors, but the million-dollar question is: how would it be better than what's possible using existing C++ language features...? Personally, I see no benefit over the solution below.

`clone()` and `create()`

The C++ FAQ documents a "virtual constructor" idiom, containing virtual create() and clone() methods to default-construct or copy-construct a new dynamically-allocated object:

class Shape {
  public:
    virtual ~Shape() { } // A virtual destructor
    virtual void draw() = 0; // A pure virtual function
    virtual void move() = 0;
    // ...
    virtual Shape* clone() const = 0; // Uses the copy constructor
    virtual Shape* create() const = 0; // Uses the default constructor
};
class Circle : public Shape {
  public:
    Circle* clone() const; // Covariant Return Types; see below
    Circle* create() const; // Covariant Return Types; see below
    // ...
};
Circle* Circle::clone() const { return new Circle(*this); }
Circle* Circle::create() const { return new Circle(); }

It's also possible to change or overload create() to accept arguments, though to match the base class / interface's virtual function signature, arguments to overrides must exactly match one of the base class overloads. With these explicit user-provided facilities, it's easy to add logging, instrumentation, alter memory allocation etc..

One solution is you can run your '.bat' file with '.vbs' file and you can run this vbs file in windows scheduler.

Set objShell = WScript.CreateObject("WScript.Shell")
objShell.Run("cron_jobs.bat"), 0, True

You can do like this and i hope it will fix your issue.

To add to the accepted answer iptables solution, I had to run two more commands on the host to open it to the outside world.

HOST> iptables -t nat -A DOCKER -p tcp --dport 443 -j DNAT --to-destination 172.17.0.2:443
HOST> iptables -t nat -A POSTROUTING -j MASQUERADE -p tcp --source 172.17.0.2 --destination 172.17.0.2 --dport https
HOST> iptables -A DOCKER -j ACCEPT -p tcp --destination 172.17.0.2 --dport https

Note: I was opening port https (443), my docker internal IP was 172.17.0.2

Note 2: These rules and temporrary and will only last until the container is restarted

For me the issue turned out to be I was using es6's right arrow functions => as opposed to function ().

Replacing => with function () resolved for me.

I had assumed it was a jQuery issue.

Something like this should do it:

for element in list_:
   sys.stdout.write(str(element))

Imagine you have a numpy array of text like in a messenger

 >>> stex[40]
 array(['Know the famous thing ...

and you want to get statistics from the corpus (text col=11) you first must get the values from dataframe (df5) and then join all records together in one single corpus:

 >>> stex = (df5.ix[0:,[11]]).values
 >>> a_str = ','.join(str(x) for x in stex)
 >>> a_str = a_str.split()
 >>> fd2 = nltk.FreqDist(a_str)
 >>> fd2.most_common(50)

I wrote this to remove all objects apart from functions from the current environment (Programming language used is R with IDE R-Studio):

    remove_list=c()                             # create a vector

      for(i in 1:NROW(ls())){                   # repeat over all objects in environment
        if(class(get(ls()[i]))!="function"){    # if object is *not* a function
         remove_list=c(remove_list,ls()[i])     # ..add to vector remove_list
         }    
      }

    rm(list=remove_list)                        # remove all objects named in remove_list

Notes-

The argument "list" in rm(list=) must be a character vector.

The name of an object in position i of the current environment is returned from ls()[i] and the object itself from get(ls()[i]). Therefore the class of an object is returned from class(get(ls()[i]))

Edit: The bitset stuff below is maybe an interesting read, but the answer itself is a bit dated. Some of this functionality is changing around in 2.x. Also Slawek points out in another answer that the terms query is an easy way to DRY up the search in this case. Refactored at the end for current best practices. —nz

You'll probably want a Bool Query (or more likely Filter alongside another query), with a should clause.

The bool query has three main properties: must, should, and must_not. Each of these accepts another query, or array of queries. The clause names are fairly self-explanatory; in your case, the should clause may specify a list filters, a match against any one of which will return the document you're looking for.

From the docs:

In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

Here's an example of what that Bool query might look like in isolation:

{
  "bool": {
    "should": [
      { "term": { "tag": "c" }},
      { "term": { "tag": "d" }}
    ]
  }
}

And here's another example of that Bool query as a filter within a more general-purpose Filtered Query:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "bool": {
        "should": [
          { "term": { "tag": "c" }},
          { "term": { "tag": "d" }}
        ]
      }
    }
  }
}

Whether you use Bool as a query (e.g., to influence the score of matches), or as a filter (e.g., to reduce the hits that are then being scored or post-filtered) is subjective, depending on your requirements.

It is generally preferable to use Bool in favor of an Or Filter, unless you have a reason to use And/Or/Not (such reasons do exist). The Elasticsearch blog has more information about the different implementations of each, and good examples of when you might prefer Bool over And/Or/Not, and vice-versa.

Elasticsearch blog: All About Elasticsearch Filter Bitsets

Update with a refactored query...

Now, with all of that out of the way, the terms query is a DRYer version of all of the above. It does the right thing with respect to the type of query under the hood, it behaves the same as the bool + should using the minimum_should_match options, and overall is a bit more terse.

Here's that last query refactored a bit:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "terms": {
        "tag": [ "c", "d" ],
        "minimum_should_match": 1
      }
    }
  }
}

I know this is old, but I would like to suggest using a linear-gradient to achieve the same effect instead of margin offset. This is will maintain any content at its original place.

I got this error when I was trying to convert a char (or string) to bytes, the code was something like this with Python 2.7:

# -*- coding: utf-8 -*-
print( bytes('ò') )

This is the way of Python 2.7 when dealing with unicode chars.

This won't work with Python 3.6, since bytes require an extra argument for encoding, but this can be little tricky, since different encoding may output different result:

print( bytes('ò', 'iso_8859_1') ) # prints: b'\xf2'
print( bytes('ò', 'utf-8') ) # prints: b'\xc3\xb2'

In my case I had to use iso_8859_1 when encoding bytes in order to solve the issue.

Hope this helps someone.

It appears that at least one of your predictors ,x1, x2, or x3, has only one factor level and hence is a constant.

Have a look at

lapply(dataframe.df[c("x1", "x2", "x3")], unique)

to find the different values.

Don't forget to take into consideration the global flag in your regexp :

var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi');    // => true
reg.test('abcdefghi');    // => false <=

This is because Regexp keeps track of the lastIndex when a new match is found.

There's always the good ol' trick:

console.log("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");

or a shorter variation of the above:

console.log('\n'.repeat('25'));

Not the most elegant solution, I know :) ... but works.

For me, I usually just print a long "-----" separator line to help make the logs easier to read.

The pipe, |, is a special-character in regex (meaning "or") and you'll have to escape it with a \.

Using your current regex:

\|.*$

I've tried this in Notepad++, as you've mentioned, and it appears to work well.

Nice and simple:

console.log("object: %O", obj)

I had the same issue. For me it helped to remove the .vs directory in the project folder.

Now in FileZilla, create a new Account 1. Host is the FTP Address - e.g. ftp.somewhere.com 2. Protocol is "SFTP-SSH File Transfer Protocol" 3. User ID is your Bluehost User Id 4. Password is your Bluehost Password 5. Click "Connect" to establish a connection with Directory Listing!

This resolve the issue with 3.10 for me. And I'm glad to have the Secure Access for all of my future file transfers. It should prevent security issues in the future.

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

The multi-framework safe shorthand for ready is:

jQuery(function($, undefined) {
    // $ is guaranteed to be short for jQuery in this scope
    // undefined is provided because it could have been overwritten elsewhere
});

This is because jQuery isn't the only framework that uses the $ and undefined variables

I had to do this to get the result that I wanted:

It refused to work with only the cell or the div and needed both.

Its not the Excel. Windows does recognize the formula, the data as a date and autocorrects. You have to change the Windows settings.

"Control Panel" (-> "Switch to Classic View") -> "Regional and Language Options" -> tab "Regional Options" -> "Customize..." -> tab "Numbers" -> And then change the symbols according to what you want.

http://www.pcreview.co.uk/forums/enable-disable-auto-convert-number-date-t3791902.html

It will work on your computer, if these settings are not changed for example on your customers' computer they will see dates instead of data.

Necromancing.

it works with IE8+ without adding any dependency on another library like jQuery !

        let script = document.createElement('script');
        script.type = 'text/javascript';
        script.src = this.withNoCache(this.m_js_files[i]);
        
        var loadNextScript = () =>

}


var ScriptLoader = new cScriptLoader(["foo.css", "Scripts/Script4.js", "foobar.css", "Scripts/Script1.js", "Scripts/Script2.js", "Scripts/Script3.js"]);
ScriptLoader.loadFiles();

If it's to load a dynamic list of scripts, write the scripts into an attribute, such as data-main, e.g. <script src="scriptloader.js" data-main="file1.js,file2.js,file3.js,etc." ></script>
and do a element.getAttribute("data-main").split(',')

such as

var target = document.currentScript || (function() {
  var scripts = document.getElementsByTagName('script');
  // Note: this is for IE as IE doesn't support currentScript
  // this does not work if you have deferred loading with async
  // e.g. <script src="..." async="async" ></script>
  // https://web.archive.org/web/20180618155601/https://www.w3schools.com/TAgs/att_script_async.asp
  return scripts[scripts.length - 1];
})();

target.getAttribute("data-main").split(',')

to obtain the list.

i=348842.
double i2=i/60000;
DecimalFormat dtime = new DecimalFormat("#.##"); 
i2= Double.valueOf(dtime.format(time));
v.setText(String.valueOf(i2));

In a Object Relational Mapping context, every object needs to have a unique identifier. You use the @Id annotation to specify the primary key of an entity.

The @GeneratedValue annotation is used to specify how the primary key should be generated. In your example you are using an Identity strategy which

Indicates that the persistence provider must assign primary keys for the entity using a database identity column.

There are other strategies, you can see more here.

As many other answers suggest the limit approach, This can be another way

You can use the indexOf method on String which will returns the first Occurance of the given character, Using that index you can get the desired output

String target = "apple=fruit table price=5" ;
int x= target.indexOf("=");
System.out.println(target.substring(x+1));

Removing pods from the project and re-installing worked for me.

There is nice GitHub repository that can completely remove the pods from the project.

Just keep the backup of your PodFile and run below commands.

• gem install cocoapods-deintegrate
• gem install cocoapods-clean
• Go to the project directory and run pod deintegrate
• Again run pod clean
• Run pod install

Clean and run.

use dataType: 'jsonp', works for me.

   async function get_ajax_data(){

       var _reprojected_lat_lng = await $.ajax({

                                type: 'GET',

                                dataType: 'jsonp',

                                data: {},

                                url: _reprojection_url,

                                error: function (jqXHR, textStatus, errorThrown) {

                                    console.log(jqXHR)

                                },

                                success: function (data) {

                                    console.log(data);



                                    // note: data is already json type, you just specify dataType: jsonp

                                    return data;

                                }

                            });





 } // function               

var option_user_selection = document.getElementById("maincourse").options[document.getElementById("maincourse").selectedIndex ].text

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:

>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
 0.00  1.00  2.00  3.00  4.00
 5.00  6.00  7.00  8.00  9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00

Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).

One situation where it is quite useful to be able to handle the x-button click event is when you are using a Form that is an MDI container. The reason is that the closeing and closed events are raised first with children and lastly with the parent. So in one scenario a user clicks the x-button to close the application and the MDI parent asks for a confirmation to proceed. In case he decides to not close the application but carry on whatever he is doing the children will already have processed the closing event potentially lost information/work whatever. One solution is to intercept the WM_CLOSE message from the Windows message loop in your main application form (i.e. which closed, terminates the application) like so:

    protected override void WndProc(ref Message m)
    {
        if (m.Msg == 0x0010) // WM_CLOSE
        {
            // If we don't want to close this window 
            if (ShowConfirmation("Are you sure?") != DialogResult.Yes) return;
        }

        base.WndProc(ref m);
    }

I've been using:

@media only screen and (min-width: 768px) {
    /* tablets and desktop */
}

@media only screen and (max-width: 767px) {
    /* phones */
}

@media only screen and (max-width: 767px) and (orientation: portrait) {
    /* portrait phones */
}

It keeps things relatively simple and allows you to do something a bit different for phones in portrait mode (a lot of the time I find myself having to change various elements for them).

Store it in the database in a field with a data type of uniqueidentifier.

did the same here needed to show "success" twice response is data from PHP

 String res=response.toString().trim;

                            Toast.makeText(sign_in.this,res,Toast.LENGTH_SHORT).show();
    if ( res.compareTo("success")==0){
    Toast.makeText(this,res,Toast.LENGTH_SHORT).show();
    }

The main difference is that the output of pip freeze can be dumped into a requirements.txt file and used later to re-construct the "frozen" environment.

In other words you can run: pip freeze > frozen-requirements.txt on one machine and then later on a different machine or on a clean environment you can do: pip install -r frozen-requirements.txt and you'll get the an identical environment with the exact same dependencies installed as you had in the original environment where you generated the frozen-requirements.txt.

For an oneliner, on linux or cygwin, you need to do public key authentication on the host, otherwise ssh will be asking for password.

gunzip -c numbers.sql.gz | ssh user@host mysql --user=user_name --password=your_password db_name

Or do port forwarding and connect to the remote mysql using a "local" connection:

ssh -L some_port:host:local_mysql_port user@host

then do the mysql connection on your local machine to localhost:some_port.

The port forwarding will work from putty too, with the similar -L option or you can configure it from the settings panel, somewhere down on the tree.

i.e we need to take multiple email addresses separated by comma, spaces or newline as below.

    var emails = EmailText.replace(","," ").replace("\n"," ").replace(" ","").split(" ");
    for(var i in emails)
        emails[i] = emails[i].replace(/(\r\n|\n|\r)/gm,"");

    emails.filter(Boolean);
    console.log(emails);

I found a simple way around this in 2005. Here are my steps:

1. Create a string parameter with values ‘Y’ and ‘N’ called ‘PageBreaks’.
2. Add a group level above the group (value) which was used to split the data to the multiple sheets in Excel.
3. Inserted into the first textbox field for this group, the expression for the ‘PageBreaks’ as such… =IIF(Parameters!PageBreaks.Value="Y",Fields!DISP_PROJECT.Value,"") Note: If the parameter =’Y’ then you will get the multiple sheets for each different value. Otherwise the field is NULL for every group record (which causes only one page break at the end).
4. Change the visibility hidden value of the new grouping row to ‘True’.
5. NOTE: When you do this it will also determine whether or not you have a page break in the view, but my users love it since they have the control.

This easy and straight forward function might help:

def check_freq(x):
    freq = {}
    for c in set(x):
       freq[c] = x.count(c)
    return freq

check_freq("abbabcbdbabdbdbabababcbcbab")
{'a': 7, 'b': 14, 'c': 3, 'd': 3}

If a comprehension is desired:

def check_freq(x):
    return {c: x.count(c) for c in set(x)}

You can easily use index of Chrome to filter out Chrome:

var ua = navigator.userAgent.toLowerCase(); 
if (ua.indexOf('safari') != -1) { 
  if (ua.indexOf('chrome') > -1) {
    alert("1") // Chrome
  } else {
    alert("2") // Safari
  }
}

On Chrome, you should be able to do this using the benchmarking extension. You need to start your chrome with the following switches:

./chrome --enable-benchmarking --enable-net-benchmarking 

In Chrome's console now you can do the following:

chrome.benchmarking.clearCache();
chrome.benchmarking.clearHostResolverCache();
chrome.benchmarking.clearPredictorCache();
chrome.benchmarking.closeConnections();

As you can tell from above commands, it not only clears the browser cache, but also clears the DNS cache and closes network connections. These are great when you're doing page load time benchmarking. Obviously you don't have to use them all if not needed (e.g. clearCache() should suffice if you need to clear the cache only and don't care about DNS cache and connections).

Replace your query with the following:

$query = mysql_query("INSERT INTO users VALUES('$username','$pass','$email')", `$Connect`);

If you're having some problem about "error compiler of class file", it's possible to resolve this by changing the project's JRE to its correspondent through Eclipse.

1. Build path
2. Configure build path
3. Change library to correspondent of table that friend shows last.
4. Create "jar file" and compile and execute.

I did that and it worked.

The spaceship method is useful when you define it in your own class and include the Comparable module. Your class then gets the >, < , >=, <=, ==, and between? methods for free.

class Card
  include Comparable
  attr_reader :value

  def initialize(value)
    @value = value
  end

  def <=> (other) #1 if self>other; 0 if self==other; -1 if self<other
    self.value <=> other.value
  end

end

a = Card.new(7)
b = Card.new(10)
c = Card.new(8)

puts a > b # false
puts c.between?(a,b) # true

# Array#sort uses <=> :
p [a,b,c].sort # [#<Card:0x0000000242d298 @value=7>, #<Card:0x0000000242d248 @value=8>, #<Card:0x0000000242d270 @value=10>]

Once an instance has been started, there is no way to change the keypair associated with the instance at a meta data level, but you can change what ssh key you use to connect to the instance.

There is a startup process on most AMIs that downloads the public ssh key and installs it in a .ssh/authorized_keys file so that you can ssh in as that user using the corresponding private ssh key.

If you want to change what ssh key you use to access an instance, you will want to edit the authorized_keys file on the instance itself and convert to your new ssh public key.

The authorized_keys file is under the .ssh subdirectory under the home directory of the user you are logging in as. Depending on the AMI you are running, it might be in one of:

/home/ec2-user/.ssh/authorized_keys
/home/ubuntu/.ssh/authorized_keys
/root/.ssh/authorized_keys

After editing an authorized_keys file, always use a different terminal to confirm that you are able to ssh in to the instance before you disconnect from the session you are using to edit the file. You don't want to make a mistake and lock yourself out of the instance entirely.

While you're thinking about ssh keypairs on EC2, I recommend uploading your own personal ssh public key to EC2 instead of having Amazon generate the keypair for you.

Here's an article I wrote about this:

Uploading Personal ssh Keys to Amazon EC2
http://alestic.com/2010/10/ec2-ssh-keys

This would only apply to new instances you run.

C programmers use the static attribute to hide variable and function declarations inside modules, much as you would use public and private declarations in Java and C++. C source files play the role of modules. Any global variable or function declared with the static attribute is private to that module. Similarly, any global variable or function declared without the static attribute is public and can be accessed by any other module. It is good programming practice to protect your variables and functions with the static attribute wherever possible.

If you want to click on all elements selected by some class, you can use this example (used on last.fm on the Loved tracks page to Unlove all).

var divs = document.querySelectorAll('.love-button.love-button--loved'); 

for (i = 0; i < divs.length; ++i) {
  divs[i].click();
};

With ES6 and Babel (cannot be run in the browser console directly)

[...document.querySelectorAll('.love-button.love-button--loved')]
   .forEach(div => { div.click(); })

You can use script like this for mac:

for f in $(curl -s -l -u user:pass ftp://your_ftp_server_ip/folder/) 
 do curl -O -u user:pass ftp://your_ftp_server_ip/folder/$f 
done

Make sure to import component in declarations array

@NgModule({
  declarations: [ExampleComponent],
  imports: [
      CommonModule,
      ExampleRoutingModule,
      ReactiveFormsModule
  ]
})

You can test if a string ends with work followed by one character like this:

theString.matches(".*work.$");

If the trailing character is optional you can use this:

theString.matches(".*work.?$");

To make sure the last character is a period . or a slash / you can use this:

theString.matches(".*work[./]$");

To test for work followed by an optional period or slash you can use this:

theString.matches(".*work[./]?$");

To test for work surrounded by periods or slashes, you could do this:

theString.matches(".*[./]work[./]$");

If the tokens before and after work must match each other, you could do this:

theString.matches(".*([./])work\\1$");

Your exact requirement isn't precisely defined, but I think it would be something like this:

theString.matches(".*work[,./]?$");

In other words:

• zero or more characters
• followed by work
• followed by zero or one , . OR /
• followed by the end of the input

Explanation of various regex items:

.               --  any character
*               --  zero or more of the preceeding expression
$               --  the end of the line/input
?               --  zero or one of the preceeding expression
[./,]           --  either a period or a slash or a comma
[abc]           --  matches a, b, or c
[abc]*          --  zero or more of (a, b, or c)
[abc]?          --  zero or one of (a, b, or c)

enclosing a pattern in parentheses is called "grouping"

([abc])blah\\1  --  a, b, or c followed by blah followed by "the first group"

Here's a test harness to play with:

class TestStuff {

    public static void main (String[] args) {

        String[] testStrings = { 
                "work.",
                "work-",
                "workp",
                "/foo/work.",
                "/bar/work",
                "baz/work.",
                "baz.funk.work.",
                "funk.work",
                "jazz/junk/foo/work.",
                "funk/punk/work/",
                "/funk/foo/bar/work",
                "/funk/foo/bar/work/",
                ".funk.foo.bar.work.",
                ".funk.foo.bar.work",
                "goo/balls/work/",
                "goo/balls/work/funk"
        };

        for (String t : testStrings) {
            print("word: " + t + "  --->  " + matchesIt(t));
        }
    }

    public static boolean matchesIt(String s) {
        return s.matches(".*([./,])work\\1?$");
    }

    public static void print(Object o) {
        String s = (o == null) ? "null" : o.toString();
        System.out.println(o);
    }

}

This may not be exactly what you're looking for (it's not an "easy" solution to send your Tabs to the bottom of the screen) but is nevertheless an interesting alternative solution I would like to flag to you :

ScrollableTabHost is designed to behave like TabHost, but with an additional scrollview to fit more items ...

maybe digging into this open-source project you'll find an answer to your question. If I see anything easier I'll come back to you.

The question is a few months old but for other people looking --

A simpler way to import a large file is to make a sub directory 'upload' in your folder c:/wamp/apps/phpmyadmin3.5.2 and edit this line in the config.inc.php file in the same directory to include the folder name $cfg['UploadDir'] = 'upload';

Then place the incoming .sql file in the folder /upload.

Working from inside the phpmyadmin console, go to the new database and import. You will now see an additional option to upload files from that folder. Chose the correct file and be a little patient. It works.

If you still get a time out error try adding $cfg['ExecTimeLimit'] = 0; to the same config.inc.php file.

I have had difficulty importing an .sql file where the user name was root and the password differed from my the root password on my new server. I simply took off the password before I exported the .sql file and the import worked smoothly.

Here is a util class for marshaling and unmarshaling objects. In my case it was a nested class, so I made it static JAXBUtils.

import javax.xml.bind.JAXB;
import java.io.StringReader;
import java.io.StringWriter;

public class JAXBUtils
{
    /**
     * Unmarshal an XML string
     * @param xml     The XML string
     * @param type    The JAXB class type.
     * @return The unmarshalled object.
     */
    public <T> T unmarshal(String xml, Class<T> type)
    {
        StringReader reader = new StringReader(xml);
        return javax.xml.bind.JAXB.unmarshal(reader, type);
    }

    /**
     * Marshal an Object to XML.
     * @param object    The object to marshal.
     * @return The XML string representation of the object.
     */
    public String marshal(Object object)
    {
        StringWriter stringWriter = new StringWriter();
        JAXB.marshal(object, stringWriter);
        return stringWriter.toString();
    }
}

Yep, just add parenthesis (calling the function). Make sure the function is in scope and actually returns something.

<ul class="ui-listview ui-radiobutton" ng-repeat="meter in meters">
  <li class = "ui-divider">
    {{ meter.DESCRIPTION }}

It is important to remember that the driver(file) must have execution permission (linux chmod +x geckodriver).

To sum up:

1. Download gecko driver
2. Add execution permission

3. Add system property:

   System.setProperty("webdriver.gecko.driver", "FILE PATH");

4. Instantiate and use the class

   WebDriver driver = new FirefoxDriver();

5. Do whatever you want

6. Close the driver

   driver.close;

Here's a few things you could do:

Export a const from the module. Depending on your use case, you could just:

export const constant1 = 33;

And import that from the module where necessary. Or, building on your static method idea, you could declare a static get accessor:

const constant1 = 33,
      constant2 = 2;
class Example {

  static get constant1() {
    return constant1;
  }

  static get constant2() {
    return constant2;
  }
}

That way, you won't need parenthesis:

const one = Example.constant1;

Babel REPL Example

Then, as you say, since a class is just syntactic sugar for a function you can just add a non-writable property like so:

class Example {
}
Object.defineProperty(Example, 'constant1', {
    value: 33,
    writable : false,
    enumerable : true,
    configurable : false
});
Example.constant1; // 33
Example.constant1 = 15; // TypeError

It may be nice if we could just do something like:

class Example {
    static const constant1 = 33;
}

But unfortunately this class property syntax is only in an ES7 proposal, and even then it won't allow for adding const to the property.

HTML

<div id="replaceMe">i need to be replaced</div>
<div id="iamReplacement">i am replacement</div>

JavaScript

jQuery('#replaceMe').replaceWith(jQuery('#iamReplacement'));

This is how I handle the public assets. Here I use Phalcon PHP's Bootstrap method.

Folder Structure

|-.htaccess*
|-application/
|-public/
  |-.htaccess**
  |-index.php***
  |-css/
  |-js/
  |-img/
  |-font/
  |-upload/
|-system

Files to edit

1. .htaccess*

   All requests to the project will be rewritten to the public/ directory making it the document root. This step ensures that the internal project folders remain hidden from public viewing and thus eliminates security threats of this kind. - Phalconphp Doc

   <IfModule mod_rewrite.c>
       RewriteEngine on
       RewriteRule  ^$ public/    [L]
       RewriteRule  (.*) public/$1 [L]
   </IfModule>
   

2. .htaccess**

   Rules will check if the requested file exists and, if it does, it doesn’t have to be rewritten by the web server module. - Phalconphp Doc

   <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteRule ^(.*)$ index.php/$1 [QSA,L]
   </IfModule>
   

3. index.php***

   Modify the application path and the system path as,

   $system_path = '../system';
   $application_folder = '../application';
   

Now you use the public folder as base_url()."public/[YOUR ASSET FOLDER]"

Hope this helps :)

Cache-Control: no-cache, no-store

These two header values can be combined to get the required effect on both IE and Firefox

This error occurs on an empty JSON file reading.

To avoid this error in NodeJS I'm checking the file's size:

const { size } = fs.statSync(JSON_FILE);
const content = size ? JSON.parse(fs.readFileSync(JSON_FILE)) : DEFAULT_VALUE;

Tested!

In Windows -> control panel -> Region -> Additional Settings -> Time -> Short Time:

Format your time as HH:mm

in the format

hh = 12 hours

HH = 24 hours

mm = minutes

tt = AM or PM

so to get the required result the format should be HH:mm and not hh:mm tt

#include <stdio.h>

int main(void)
{
    int number = 7; /* signed */
    int vbool[8 * sizeof(int)];
    int i;
        for (i = 0; i < 8 * sizeof(int); i++)
        {
            vbool[i] = number<<i < 0;   
            printf("%d", vbool[i]);
        }
    return 0;
}

If you can't use box-sizing (e.g. when you convert HTML to PDF using iText). Try this:

CSS

.input-wrapper { border: 1px solid #ccc; padding: 0 5px; min-height: 20px; } 
.input-wrapper input[type=text] { border: none; height: 20px; width: 100%; padding: 0; margin: 0; }

HTML

<div class="input-wrapper">
     <input type="text" value="" name="city"/>
</div>

Assuming you have an ArrayList that contains characters, you could do this:

List<Character> list = new ArrayList<Character>();
list.addAll(Arrays.asList('+', '-', '*', '^'));

The problem is with your notificationId. Think it as an array index. Each time you update your notification, the notificationId is the place it takes to store value. As you are not incrementing your int value (in this case, your notificationId), this always replaces the previous one. The best solution I guess is to increment it just after you update a notification. And if you want to keep it persistent, then you can store the value of your notificationId in sharedPreferences. Whenever you come back, you can just grab the last integer value (notificationId stored in sharedPreferences) and use it.

Recently I wanted to learn how to compile Intel x86 on Mac OS X:

For nasm:

-o hello.tmp - outfile
-f macho - specify format
Linux - elf or elf64
Mac OSX - macho

For ld:

-arch i386 - specify architecture (32 bit assembly)
-macosx_version_min 10.6 (Mac OSX - complains about default specification)
-no_pie (Mac OSX - removes ld warning)
-e main - specify main symbol name (Mac OSX - default is start)
-o hello.o - outfile

For Shell:

./hello.o - execution

One-liner:

nasm -o hello.tmp -f macho hello.s && ld -arch i386 -macosx_version_min 10.6 -no_pie -e _main -o hello.o hello.tmp && ./hello.o

Let me know if this helps!

I wrote how to do it on my blog here:

http://blog.burrowsapps.com/2013/07/how-to-compile-helloworld-in-intel-x86.html

For a more verbose explanation, I explained on my Github here:

https://github.com/jaredsburrows/Assembly

You are getting AttributeError because you're calling groups on None, which hasn't any methods.

regex.search returning None means the regex couldn't find anything matching the pattern from supplied string.

when using regex, it is nice to check whether a match has been made:

Result = re.search(SearchStr, htmlString)

if Result:
    print Result.groups()

I was looking into this issue a bit for my own purposes; I had a slice of structs (including some pointers) and I wanted to make sure I got it right; ended up on this thread, and wanted to share my results.

To practice, I did a little go playground: https://play.golang.org/p/9i4gPx3lnY

which evals to this:

package main

import "fmt"

type Blah struct {
    babyKitten int
    kittenSays *string
}

func main() {
    meow := "meow"
    Blahs := []Blah{}
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{2, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    //fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
    Blahs = nil
    meow2 := "nyan"
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow2})
    fmt.Printf("Blahs: %v\n", Blahs)
    fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
}

Running that code as-is will show the same memory address for both "meow" and "meow2" variables as being the same:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
Blahs: []
Blahs: [{1 0x1030e0f0}]
kittenSays: nyan

which I think confirms that the struct is garbage collected. Oddly enough, uncommenting the commented print line, will yield different memory addresses for the meows:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
kittenSays: meow
Blahs: []
Blahs: [{1 0x1030e0f8}]
kittenSays: nyan

I think this may be due to the print being deferred in some way (?), but interesting illustration of some memory mgmt behavior, and one more vote for:

[]MyStruct = nil

This might work for you:

sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1

I ran into this in IntelliJ and fixed it by adding the following to my pom:

<!-- logging dependencies -->
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>${logback.version}</version>
        <exclusions>
            <exclusion>
                <!-- Defined below -->

    </dependency>

fyi <form> supports :before / :after as well, might be of help if you wrap your <input> element with it... (got myself a design issue with that too)

So, I would like to explain the scenario where I had to make use of this solution. Basically, I wanted to undo the background-color attribute set by another CSS. The expected end result was to make it look as though the original CSS had never applied the background-color attribute . Setting background-color:transparent; made that effective.

A pointer to member function is different from a pointer to function. In order to use a member function through a pointer you need a pointer to it (obviously ) and an object to apply it to. So the appropriate version of function1 would be

void function1(void (aClass::*function)(int, int), aClass& a) {
    (a.*function)(1, 1);
}

and to call it:

aClass a; // note: no parentheses; with parentheses it's a function declaration
function1(&aClass::test, a);

if you want to only search with attribute name with any value

from bs4 import BeautifulSoup
import re

soup= BeautifulSoup(html.text,'lxml')
results = soup.findAll("td", {"valign" : re.compile(r".*")})

as per Steve Lorimer better to pass True instead of regex

results = soup.findAll("td", {"valign" : True})

Java uses double quotes for "String" and single quotes for 'C'haracters.

add KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha??1 to your sshd_config on the server.

This worked, but make sure you restart sshd: sudo service sshd restart

As I didn't find what I was looking for, I will share what I actually wanted to achieve when I ended in this question.

Scenario: I have 3 different API's with same possible response and therefore I would like to handle the completion and error handling of the promises in a single function. This is what I did:

1. Create a handler function:

  private handleHttpPromise = (promise: Promise<any>) => {
    promise
      .then((response: any) => {
        // do something with the response
        console.log(response);
      })
      .catch((error) => {
        // do something with the error
        console.log(error);
      });
  };

2. Send your promises to the created handler

  switch (method) {
    case 'get': {
      this.handleHttpPromise(apiService.get(url));
      break;
    }
    case 'post': {
      if (jsonData) {
        this.handleHttpPromise(apiService.post(url, jsonData));
      }
      break;
    }
    // (...)
  }

I have used Netbeans for java, and it works great. Not sure how it works with C++, though.

This solution:

1. has timeout
2. polling works also after error response

Minimum version of jQuery is 1.12

$(document).ready(function () {
  function poll () {
    $.get({
      url: '/api/stream/',
      success: function (data) {
        console.log(data)
      },
      timeout: 10000                    // == 10 seconds timeout
    }).always(function () {
      setTimeout(poll, 30000)           // == 30 seconds polling period
    })
  }

  // start polling
  poll()
})

Improved Version of "Josh Marinacci" answer , it will read beyond Z column (i.e. AA1).

var XLSX = require('xlsx');
var workbook = XLSX.readFile('test.xlsx');
var sheet_name_list = workbook.SheetNames;
sheet_name_list.forEach(function(y) {
    var worksheet = workbook.Sheets[y];
    var headers = {};
    var data = [];
    for(z in worksheet) {
        if(z[0] === '!') continue;
        //parse out the column, row, and value
        var tt = 0;
        for (var i = 0; i < z.length; i++) {
            if (!isNaN(z[i])) {
                tt = i;
                break;
            }
        };
        var col = z.substring(0,tt);
        var row = parseInt(z.substring(tt));
        var value = worksheet[z].v;

        //store header names
        if(row == 1 && value) {
            headers[col] = value;
            continue;
        }

        if(!data[row]) data[row]={};
        data[row][headers[col]] = value;
    }
    //drop those first two rows which are empty
    data.shift();
    data.shift();
    console.log(data);
});

Use the Arrays.toString() function. It keeps your code short and readable. It uses a string builder internally, thus, it's also efficient. To get rid of the extra characters, you might chose to eliminate them using the String.replace() function, which, admittedly, reduces readability again.

String str = Arrays.toString(arr).replaceAll(", |\\[|\\]", "");

This is similar to the answer of Tris Nefzger, but without the lengthy substring construction to get rid of the square brackets.

Explanation of the Regex: "|" means any of ", " and "[" and "]". The "\\" tells the Java String that we are not meaning some special character (like a new line "\n" or a tab "\t") but a real backslash "\". So instead of "\\[", the Regex interpreter reads "\[", which tells it that we mean a literal square bracket and do not want to use it as part of the Regex language (for instance, "[^3]*" denotes any number of characters, but none of them should be "3").

try this : here select is your select element

let select = document.getElementsByClassName('lstSelected')[0],
    options = select.options,
    len = options.length,
    data='',
    i=0;
while (i<len){
    if (options[i].selected)
        data+= "&" + select.name + '=' + options[i].value;
    i++;
}
return data;

Data is in the form of query string i.e.name=value&name=anotherValue
