you should add plug in to your local setting of firefox in your user home

 vladimir@shinsengumi ~/.mozilla/plugins $ pwd

The feature that I'm missing a lot from postman in Firefox extensions is WebView
(preview when API returns HTML).

Now I'm settled with Fiddler (Inspectors > WebView)

Webstorm 11 and 2016.2.3

Enable Node.js Core library in Webstorm settings.

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

Request header needs to be set as per below image.

request body can be passed as json string in text area.

AdBlockers usually have some rules, i.e. they match the URIs against some type of expression (sometimes they also match the DOM against expressions, not that this matters in this case).

Having rules and expressions that just operate on a tiny bit of text (the URI) is prone to create some false-positives...

Besides instructing your users to disable their extensions (at least on your site) you can also get the extension and test which of the rules/expressions blocked your stuff, provided the extension provides enough details about that. Once you identified the culprit, you can either try to avoid triggering the rule by using different URIs, report the rule as incorrect or overly-broad to the team that created it, or both. Check the docs for a particular add-on on how to do that.

For example, AdBlock Plus has a Blockable items view that shows all blocked items on a page and the rules that triggered the block. And those items also including XHR requests.

just replace 'myselect' with your id

to disable->

document.getElementById("mySelect").disabled = true;  

to enable->

document.getElementById("mySelect").disabled = false; 

Expanding on Felix Turner s response, here is how I would use this approach with the fetch API.

async function createFile(){
  let response = await fetch('http://127.0.0.1:8080/test.jpg');
  let data = await response.blob();
  let metadata = {
    type: 'image/jpeg'
  };
  let file = new File([data], "test.jpg", metadata);
  // ... do something with the file or return it
}
createFile();

Have you escaped your forward slashes( / )? I've had trouble with those before

MIME stands for Multipurpose Internet Mail Extensions. It's a way of identifying files on the Internet according to their nature and format.

For example, using the Content-type header value defined in a HTTP response, the browser can open the file with the proper extension/plugin.

Internet Media Type (also Content-type) is the same as a MIME type. MIME types were originally created for emails sent using the SMTP protocol. Nowadays, this standard is used in a lot of other protocols, hence the new naming convention "Internet Media Type".

A MIME type is a string identifier composed of two parts: a type and a subtype.

• The "type" refers to a logical grouping of many MIME types that are closely related to each other; it's no more than a high level category.
• "subtypes" are specific to one file type within the "type".

The x- prefix of a MIME subtype simply means that it's non-standard.
The vnd prefix means that the MIME value is vendor specific.

Use nsIJSON if this is for a FF extension:

var req = new XMLHttpRequest;
req.overrideMimeType("application/json");
req.open('GET', BITLY_CREATE_API + encodeURIComponent(url) + BITLY_API_LOGIN, true);
var target = this;
req.onload = function() {target.parseJSON(req, url)};
req.send(null);

parseJSON: function(req, url) {
if (req.status == 200) {
  var jsonResponse = Components.classes["@mozilla.org/dom/json;1"]
      .createInstance(Components.interfaces.nsIJSON.decode(req.responseText);
  var bitlyUrl = jsonResponse.results[url].shortUrl;
}

For a webpage, just use JSON.parse instead of Components.classes["@mozilla.org/dom/json;1"].createInstance(Components.interfaces.nsIJSON.decode

Add to the list:

In Emacs mode, hit Esc, followed by R, will delete the whole line.

I don't know why, just happens to find it. Maybe it's not used for delete line but happens to have the same effect. If someone knows, please tell me, thanks :)

Works in Bash, but won't work in Fish.

The Run/Debug configuration you're using is meant to let you run Maven on your workspace as if from the command line without leaving Eclipse.

Assuming your tests are JUnit based you should be able to debug them by choosing a source folder containing tests with the right button and choose Debug as... -> JUnit tests.

Reading these answers, I can see a lot relating to Spring version 4.x, I am using version 3.2.0 for various reasons. So things like json support straight from the content() is not possible.

I found that using MockMvcResultMatchers.jsonPath is really easy and works a treat. Here is an example testing a post method.

The bonus with this solution is that you're still matching on attributes, not relying on full json string comparisons.

(Using org.springframework.test.web.servlet.result.MockMvcResultMatchers)

String expectedData = "some value";
mockMvc.perform(post("/endPoint")
                .contentType(MediaType.APPLICATION_JSON)
                .content(mockRequestBodyAsString.getBytes()))
                .andExpect(status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.data").value(expectedData));

The request body was just a json string, which you can easily load from a real json mock data file if you wanted, but I didnt include that here as it would have deviated from the question.

The actual json returned would have looked like this:

{
    "data":"some value"
}

For Me I just wanted to see the error in my VBA application so in the function I created the below code..

The concern is we should not use ALLOW_ALL_HOSTNAME_VERIFIER.

How about I implement my own hostname verifier?

class MyHostnameVerifier implements org.apache.http.conn.ssl.X509HostnameVerifier
{
    @Override
    public boolean verify(String host, SSLSession session) {
        String sslHost = session.getPeerHost();
        System.out.println("Host=" + host);
        System.out.println("SSL Host=" + sslHost);    
        if (host.equals(sslHost)) {
            return true;
        } else {
            return false;
        }
    }

    @Override
    public void verify(String host, SSLSocket ssl) throws IOException {
        String sslHost = ssl.getInetAddress().getHostName();
        System.out.println("Host=" + host);
        System.out.println("SSL Host=" + sslHost);    
        if (host.equals(sslHost)) {
            return;
        } else {
            throw new IOException("hostname in certificate didn't match: " + host + " != " + sslHost);
        }
    }

    @Override
    public void verify(String host, X509Certificate cert) throws SSLException {
        throw new SSLException("Hostname verification 1 not implemented");
    }

    @Override
    public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {
        throw new SSLException("Hostname verification 2 not implemented");
    }
}

Let's test against https://www.rideforrainbows.org/ which is hosted on a shared server.

public static void main (String[] args) throws Exception {
    //org.apache.http.conn.ssl.SSLSocketFactory sf = org.apache.http.conn.ssl.SSLSocketFactory.getSocketFactory();
    //sf.setHostnameVerifier(new MyHostnameVerifier());
    //org.apache.http.conn.scheme.Scheme sch = new Scheme("https", 443, sf);

    org.apache.http.client.HttpClient client = new DefaultHttpClient();
    //client.getConnectionManager().getSchemeRegistry().register(sch);
    org.apache.http.client.methods.HttpPost post = new HttpPost("https://www.rideforrainbows.org/");
    org.apache.http.HttpResponse response = client.execute(post);
    java.io.InputStream is = response.getEntity().getContent();
    java.io.BufferedReader rd = new java.io.BufferedReader(new java.io.InputStreamReader(is));
    String line;
    while ((line = rd.readLine()) != null) { 
        System.out.println(line);
    }
}

SSLException:

Exception in thread "main" javax.net.ssl.SSLException: hostname in certificate didn't match: www.rideforrainbows.org != stac.rt.sg OR stac.rt.sg OR www.stac.rt.sg
at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:231)
...

Do with MyHostnameVerifier:

public static void main (String[] args) throws Exception {
    org.apache.http.conn.ssl.SSLSocketFactory sf = org.apache.http.conn.ssl.SSLSocketFactory.getSocketFactory();
    sf.setHostnameVerifier(new MyHostnameVerifier());
    org.apache.http.conn.scheme.Scheme sch = new Scheme("https", 443, sf);

    org.apache.http.client.HttpClient client = new DefaultHttpClient();
    client.getConnectionManager().getSchemeRegistry().register(sch);
    org.apache.http.client.methods.HttpPost post = new HttpPost("https://www.rideforrainbows.org/");
    org.apache.http.HttpResponse response = client.execute(post);
    java.io.InputStream is = response.getEntity().getContent();
    java.io.BufferedReader rd = new java.io.BufferedReader(new java.io.InputStreamReader(is));
    String line;
    while ((line = rd.readLine()) != null) { 
        System.out.println(line);
    }
}

Shows:

Host=www.rideforrainbows.org
SSL Host=www.rideforrainbows.org

At least I have the logic to compare (Host == SSL Host) and return true.

The above source code is working for httpclient-4.2.3.jar and httpclient-4.3.3.jar.

Sometimes if you change the starting activity you have to click edit in the run dropdown play button and in app change the Launch Options Activity to the one you have set the LAUNCHER intent filter in the manifest.

Android Studio 1.0 makes it easier to add a .jar file library to a project. Go to File>Project Structure and then Click on Dependencies. Over there you can add .jar files from your computer to the project. You can also search for libraries from maven.

When you create your own key pair object, you should face a few thing.

First, you should be aware of implementing hashCode() and equals(). You will need to do this.

Second, when implementing hashCode(), make sure you understand how it works. The given user example

public int hashCode() {
    return this.x ^ this.y;
}

is actually one of the worst implementations you can do. The reason is simple: you have a lot of equal hashes! And the hashCode() should return int values that tend to be rare, unique at it's best. Use something like this:

public int hashCode() {
  return (X << 16) + Y;
}

This is fast and returns unique hashes for keys between -2^16 and 2^16-1 (-65536 to 65535). This fits in almost any case. Very rarely you are out of this bounds.

Third, when implementing equals() also know what it is used for and be aware of how you create your keys, since they are objects. Often you do unnecessary if statements cause you will always have the same result.

If you create keys like this: map.put(new Key(x,y),V); you will never compare the references of your keys. Cause everytime you want to acces the map, you will do something like map.get(new Key(x,y));. Therefore your equals() does not need a statement like if (this == obj). It will never occure.

Instead of if (getClass() != obj.getClass()) in your equals() better use if (!(obj instanceof this)). It will be valid even for subclasses.

So the only thing you need to compare is actually X and Y. So the best equals() implementation in this case would be:

public boolean equals (final Object O) {
  if (!(O instanceof Key)) return false;
  if (((Key) O).X != X) return false;
  if (((Key) O).Y != Y) return false;
  return true;
}

So in the end your key class is like this:

public class Key {

  public final int X;
  public final int Y;

  public Key(final int X, final int Y) {
    this.X = X;
    this.Y = Y;
  }

  public boolean equals (final Object O) {
    if (!(O instanceof Key)) return false;
    if (((Key) O).X != X) return false;
    if (((Key) O).Y != Y) return false;
    return true;
  }

  public int hashCode() {
    return (X << 16) + Y;
  }

}

You can give your dimension indices X and Y a public access level, due to the fact they are final and do not contain sensitive information. I'm not a 100% sure whether private access level works correctly in any case when casting the Object to a Key.

If you wonder about the finals, I declare anything as final which value is set on instancing and never changes - and therefore is an object constant.

Best and most generic way to control the music is to create a mother Activity in which you override startActivity(Intent intent) - in it you put shouldPlay=true, and onBackPressed() - in it you put shouldPlay = true. onStop - in it you put a conditional mediaPlayer.stop with shouldPlay as condition

Then, just extend the mother activity to all other activities, and no code duplicating is needed.

In Eclipse:

Window -> Preferences -> Android -> Lint Error Checking.

In the list find an entry with ID = ProtectedPermission. Set the Severity to something lower than Error. This way you can still compile the project using Eclipse.

In Android Studio:

File -> Settings -> Editor -> Inspections

Under Android Lint, locate Using system app permission. Either uncheck the checkbox or choose a Severity lower than Error.

Three types of commenting are supported

1. Hash base single line commenting using #

   Select * from users ; # this will list users
   

   2. Double Dash commenting using --

   Select * from users ; -- this will list users

Note : Its important to have single white space just after --

3) Multi line commenting using /* */

Select * from users ; /* this will list users */

<div style="float: left;">Left Div</div>
<div style="float: right;">Right Div</div>

I also liked pandas simple grouping. it's powerful, simple and most adequate for large data set

result = pandas.DataFrame(input).groupby(1).groups

Listen to window:scroll event for window/document level scrolling and element's scroll event for element level scrolling.

window:scroll

@HostListener('window:scroll', ['$event'])
onWindowScroll($event) {

}

or

<div (window:scroll)="onWindowScroll($event)">

scroll

@HostListener('scroll', ['$event'])
onElementScroll($event) {

}

or

<div (scroll)="onElementScroll($event)">

@HostListener('scroll', ['$event']) won't work if the host element itself is not scroll-able.

Examples

• Using Event Binding
• Using HostListener

For others come to here:
If you happen to put your docker command in a file, say run.sh, check your line separator. In Linux, it should be LR, otherwise you would get the same error.

github adds a reference to the commit if it contains #issuenbr (discovered this by chance).

Have you tried disabling buffering?

setvbuf(fd, NULL, _IONBF, 0);

In Java is almost the same:

try
{
   ...
}
catch (Exception e)
{
   if (e instanceof FooException)
     throw e;
}

To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:

output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6

# output = 
#           [,1] [,2] [,3]
#     [1,]    1    3    5
#     [2,]    2    4    6

output = output[,-1] # this removes column 1 for all rows

# output = 
#           [,1] [,2]
#     [1,]    3    5
#     [2,]    4    6

So you can just add output = output[,-1]after the for loop in your original code.

Try using viewport (vh, vm) units of measure at the body level

html, body { margin: 0; padding: 0; } body { min-height: 100vh; }

Use vh units for horizontal margins, paddings, and borders on the body and subtract them from the min-height value.

I've had bizarre results using vh,vm units on elements within the body, especially when re-sizing.

You can do so by creating an array of dtype=object. If you try to assign a long string to a normal numpy array, it truncates the string:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'], 
      dtype='|S6')

But when you use dtype=object, you get an array of python object references. So you can have all the behaviors of python strings:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)

Indeed, because it's an array of objects, you can assign any kind of python object to the array:

>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)

However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:

>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop

I have fix for this issue,

example if you are assigning some values to DataFrame

[*] symbol has shown this because of the script running

to see the outout of the script have to mention df like this, output

Solution for all screen sizes and dynamic orientation:

import html2canvas from 'html2canvas'
import jsPDF from 'jspdf'

export default async function downloadComponentInPDF(Component: HTMLElement) {
  await html2canvas(Component).then((canvas) => {
    const componentWidth = Component.offsetWidth
    const componentHeight = Component.offsetHeight

    const orientation = componentWidth >= componentHeight ? 'l' : 'p'

    const imgData = canvas.toDataURL('image/png')
    const pdf = new jsPDF({
    orientation,
    unit: 'px'
  })

    pdf.internal.pageSize.width = componentWidth
    pdf.internal.pageSize.height = componentHeight

    pdf.addImage(imgData, 'PNG', 0, 0, componentWidth, componentHeight)
    pdf.save('download.pdf')
  })
}

pretty sure you just want the plain old replace function. use like this:

myString.replace('username1','');

i suppose if you want to remove the trailing comma do this instead:

myString.replace('username1,','');

edit:

here is your site specific code:

jQuery("#post_like_list-510").text().replace(...) 

believe there should be a way in accessing file system.

Include node.d.ts using npm i @types/node. And then create a new tsconfig.json file (npx tsc --init) and create a .ts file as followed:

import fs from 'fs';
fs.readFileSync('foo.txt','utf8');

You can use other functions in fs as well : https://nodejs.org/api/fs.html

• OPTIONS Identifying which HTTP methods a resource supports, e.g. can we DELETE it or update it via a PUT?
• HEAD Checking whether a resource has changed. This is useful when maintaining a cached version of a resource
• HEAD Retrieving metadata about the resource, e.g. its media type or its size, before making a possibly costly retrieval
• HEAD, OPTIONS Testing whether a resource exists and is accessible. For example, validating user-submitted links in an application

Here is nice and concise article about how HEAD and OPTIONS fit into RESTful architecture.

if you know the file name, but don't know the file extention you can use this function:

public function showImage($name)
    {

         $types = [
             'gif'=> 'image/gif',
             'png'=> 'image/png',
             'jpeg'=> 'image/jpeg',
             'jpg'=> 'image/jpeg',
         ];
         $root_path  = '/var/www/my_app'; //use your framework to get this properly ..
         foreach($types as $type=>$meta){
             if(file_exists($root_path .'/uploads/'.$name  .'.'. $type)){
                 header('Content-type: ' . $meta);
                 readfile($root_path .'/uploads/'.$name .'.'. $type);
                 return;
             }
         }
    }

Note: the correct content-type for JPG files is image/jpeg.

Yes, you can set the icons to the white color. here is how it worked for me.

Bootstrap <3

HTML

<i class="icon-ok icon-white"></i>

This would make your icon appear white.

This problem mostly occurs due to the error in setText() method

Solution is simple put your Integer value by converting into string type as

textview.setText(Integer.toString(integer_value));

I've made a simple-as-possible extension for that purpose.

extension Array where Element: Equatable {

    func containsHowMany(_ elem: Element) -> Int {
        return reduce(0) { $1 == elem ? $0 + 1 : $0 }
    }

    func duplicatesRemoved() -> Array {
        return self.filter { self.containsHowMany($0) == 1 }
    }

    mutating func removeDuplicates() {
        self = self.duplicatesRemoved(()
    }
}

You can use duplicatesRemoved() to get a new array, whose duplicate elements are removed, or removeDuplicates() to mutate itself. See:

let arr = [1, 1, 1, 2, 2, 3, 4, 5, 6, 6, 6, 6, 6, 7, 8]

let noDuplicates = arr.duplicatesRemoved()
print(arr) // [1, 1, 1, 2, 2, 3, 4, 5, 6, 6, 6, 6, 6, 7, 8]
print(noDuplicates) // [1, 2, 3, 4, 5, 6, 7, 8]

arr.removeDuplicates()
print(arr) // [1, 2, 3, 4, 5, 6, 7, 8]

            .pipe(jsMinify())
            .pipe(gulp.dest('dist/app/'));
        var js1 = gulp.src('dist/app/app_libs_bundle.js')
            .pipe(jsMinify(options))
            .pipe(gulp.dest('dist/app/'));
        var css = gulp.src('dist/css/styles.min.css');
        return merge(js,js1, css);
    });

5) In index.html for production 

    <html>
    <head>
        <title>Hello</title>

        <meta name="viewport" content="width=device-width, initial-scale=1">
        <meta charset="utf-8" />

       <link rel="stylesheet" href="app/css/styles.min.css" />   
       <script type="text/javascript" src="app/shims.js"></script>  
       <base href="/">
    </head>
     <body>
    <my-app>Loading...</my-app>
     <script type="text/javascript" src="app/app_libs_bundle.js"></script> 
    </body>

    </html>

 6) Now just copy your dist folder to '/www' in wamp server node need to copy node_modules in www.

MACRO Solution (2020)

Here is the macro that I use for safe string instead of getting "(null)" string on a UILabel for example:

#define SafeString(STRING) ([STRING length] == 0 ? @"" : STRING)

let say you have an member class and name property, and name is nil:

NSLog(@"%@", member.name); // prints (null) on UILabel

with macro:

NSLog(@"%@", SafeString(member.name)); // prints empty string on UILabel

nice and clean

Extension Solution (2020)

If you prefer checking nil Null and empty string in your project you can use my extension line below:

NSString+Extension.h

///
/// Checks if giving String is an empty string or a nil object or a Null.
/// @param string string value to check.
///
+ (BOOL)isNullOrEmpty:(NSString*)string;

NSString+Extension.m

+ (BOOL)isNullOrEmpty:(NSString*)string {
    if (string) { // is not Nil
        NSRange range = [string rangeOfString:string];
        BOOL isEmpty = (range.length <= 0 || [string isEqualToString:@" "]);
        BOOL isNull = string == (id)[NSNull null];

        return (isNull || isEmpty);
    }

    return YES;
}

Example Usage

if (![NSString isNullOrEmpty:someTitle]) {
    // You can safely use on a Label or even add in an Array for example. Remember: Arrays don't like the nil values!
}

I see the many types of uses, but I find this layout more useful as a reference tool:

SELECT DATE_FORMAT('2004-01-20' ,'%Y-%m-01');

It's usually in your MySQL installation folder like in C:\Program Files\MySQL\MySQL Server 5.5\my.ini or C:\xampp\mysql\bin

If it's not there, it's highly possible that you have none, and that MySQL is just loading default values.

You might have to enable hidden Files and Folders to see it. Go to Folder Options: in any folder, go to the top horizontal main text menu >> Tools >> Folder Options. Enable 'View Hidden Files and Folders', and 'View Protected System Files', save & exit

I think you should put

`

(backtick) symbols around your variable.

The first draft of Selectors Level 4 outlines a way to explicitly set the subject of a selector. This would allow the OP to style the list element with the selector $li > a.active

From Determining the Subject of a Selector:

For example, the following selector represents a list item LI unique child of an ordered list OL:

OL > LI:only-child

However the following one represents an ordered list OL having a unique child, that child being a LI:

$OL > LI:only-child

The structures represented by these two selectors are the same, but the subjects of the selectors are not.

Edit: Given how "drafty" a draft spec can be, it's best to keep tabs on this by checking the CSSWG's page on selectors level 4.

This worked for me:

server {
  listen  80; 
  server_name example.com www.example.com;

  location / { 
    proxy_pass                          http://127.0.0.1:8080/;
    proxy_set_header Host               $host;
    proxy_set_header X-Real-IP          $remote_addr;  
    proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
  }
}

If it does not work for you look at the logs at sudo tail -f /var/log/nginx/error.log

As GateKiller said you need to change the maxRequestLength. You may also need to change the executionTimeout in case the upload speed is too slow. Note that you don't want either of these settings to be too big otherwise you'll be open to DOS attacks.

The default for the executionTimeout is 360 seconds or 6 minutes.

You can change the maxRequestLength and executionTimeout with the httpRuntime Element.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <httpRuntime maxRequestLength="102400" executionTimeout="1200" />
    </system.web>
</configuration>

EDIT:

If you want to handle the exception regardless then as has been stated already you'll need to handle it in Global.asax. Here's a link to a code example.

I looked to MS to find the answers. The first solution assumes the user account running the application process has access to the shared folder or drive (Same domain). Make sure your DNS is resolved or try using IP address. Simply do the following:

 DirectoryInfo di = new DirectoryInfo(PATH);
 var files = di.EnumerateFiles("*.*", SearchOption.AllDirectories);

If you want across different domains .NET 2.0 with credentials follow this model:

WebRequest req = FileWebRequest.Create(new Uri(@"\\<server Name>\Dir\test.txt"));

        req.Credentials = new NetworkCredential(@"<Domain>\<User>", "<Password>");
        req.PreAuthenticate = true;

        WebResponse d = req.GetResponse();
        FileStream fs = File.Create("test.txt");

        // here you can check that the cast was successful if you want. 
        fs = d.GetResponseStream() as FileStream;
        fs.Close();

The solution is to put an N in front of both the type and the SQL string to indicate it is a double-byte character string:

DECLARE @SQL NVARCHAR(100) 
SET @SQL = N'SELECT TOP 1 * FROM sys.tables' 
EXECUTE sp_executesql @SQL

U can try below code snippet

    public Uri getUri(ContentResolver cr, String path){
    Uri mediaUri = MediaStore.Files.getContentUri(VOLUME_NAME);
    Cursor ca = cr.query(mediaUri, new String[] { MediaStore.MediaColumns._ID }, MediaStore.MediaColumns.DATA + "=?", new String[] {path}, null);
    if (ca != null && ca.moveToFirst()) {
        int id = ca.getInt(ca.getColumnIndex(MediaStore.MediaColumns._ID));
        ca.close();
        return  MediaStore.Files.getContentUri(VOLUME_NAME,id);
    }
    if(ca != null) {
        ca.close();
    }
    return null;
}

I had the same problem when i have trying to read xml that was extracted from archive to memory stream.

 MemoryStream SubSetupStream = new MemoryStream();
        using (ZipFile archive = ZipFile.Read(zipPath))
        {
            archive.Password = "SomePass";
            foreach  (ZipEntry file in archive)
            {
                file.Extract(SubSetupStream);
            }
        }

Problem was in these lines:

XmlDocument doc = new XmlDocument();
    doc.Load(SubSetupStream);

And solution is (Thanks to @Phil):

        if (SubSetupStream.Position>0)
        {
            SubSetupStream.Position = 0;
        }

To set it programmatically in Activity.java:

public void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setTheme(R.style.MyTheme); // (for Custom theme)
  setTheme(android.R.style.Theme_Holo); // (for Android Built In Theme)

  this.setContentView(R.layout.myactivity);

To set in Application scope in Manifest.xml (all activities):

 <application
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To set in Activity scope in Manifest.xml (single activity):

  <activity
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To build a custom theme, you will have to declare theme in themes.xml file, and set styles in styles.xml file.

sometimes there's a difference between the local cached version of origin master (origin/master) and the true origin master.

If you run git remote update this will resynch origin master with origin/master

First off, you must save your work book as a macro enabled work book. So it would need to be xlsm not an xlsx. Otherwise, excel will disable the macro's due to not being macro enabled.

Set your vbscript (C:\excel\tester.vbs). The example sub "test()" must be located in your modules on the excel document.

dim eApp
set eApp = GetObject("C:\excel\tester.xlsm")
eApp.Application.Run "tester.xlsm!test"
set eApp = nothing

Then set your Schedule, give it a name, and a username/password for offline access.

Then you have to set your actions and triggers.

Set your schedule(trigger)

Action, set your vbscript to open with Cscript.exe so that it will be executed in the background and not get hung up by any error handling that vbcript has enabled.

$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

You have a few choices:

1. typeof(IMyInterface).IsAssignableFrom(typeof(MyType))

2. typeof(MyType).GetInterfaces().Contains(typeof(IMyInterface))

For a generic interface, it’s a bit different.

typeof(MyType).GetInterfaces().Any(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(IMyInterface<>))

You can not alter constraints ever but you can drop them and then recreate.

Have look on this

ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;

and then recreate it with ON DELETE CASCADE like this

ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
    ON DELETE CASCADE;

hope this help

In android studio you may see the following folder drawable xhdpi, drawable-hdpi, drawable-mdpi and more... You can put images of different dpi in these folder accordingly and android will take care which images should be draw according to the screen density of device.

NOTE: You have to put the images with the same name.

My few cents to previous excellent replies. the site www.sqlite.org works on a sqlite database. Here is the link when the author (Richard Hipp) replies to a similar question.

While gcc 3.2.3 was more forgiving of the issue, gcc 4.1.2 is highlighting a potentially serious issue for the linking of your program later. Rather then trying to suppress the error you should make the forward declaration match the function declaration.

If you intended for the function to be globally available (as per the forward declaration) then don't subsequently declare it as static. Likewise if it's indented to be locally scoped then make the forward declaration static to match.

Don't give exact heights, but relative ones, adding up to 100%. For example:

  #content {height: 80%;}
  #footer {height: 20%;}

Add in

 html, body {height: 100%;}

With Winforms you can use Form.BackColor to do this.
From within the Form's code:

BackColor = Color.LightPink;

If you mean a WPF Window you can use the Background property.
From within the Window's code:

Background = Brushes.LightPink;

You can use following methods to get current date in milliseconds.

[[NSDate date] timeIntervalSince1970];

OR

double CurrentTime = CACurrentMediaTime();

from documentation http://www.w3.org/TR/XMLHttpRequest/#the-status-attribute means a request was cancelled before going anywhere

Yeah you can do some tricky works to simulate what you want:

1) Call your controller from a view by ajax. 2) Return your View

3) Use something like the following in the success (or maybe error! error works for me!) section of your $.ajax request:

$("#imgPrint").click(function () {
        $.ajax({
            url: ...,
            type: 'POST', dataType: 'json',
            data: $("#frm").serialize(),
            success: function (data, textStatus, jqXHR) {
                //Here it is:
                //Gets the model state
                var isValid = '@Html.Raw(Json.Encode(ViewData.ModelState.IsValid))'; 
                // checks that model is valid                    
                if (isValid == 'true') {
                    //open new tab or window - according to configs of browser
                    var w = window.open();
                    //put what controller gave in the new tab or win 
                    $(w.document.body).html(jqXHR.responseText);
                }
                $("#imgSpinner1").hide();
            },
            error: function (jqXHR, textStatus, errorThrown) {
                // And here it is for error section. 
                //Pay attention to different order of 
                //parameters of success and error sections!
                var isValid = '@Html.Raw(Json.Encode(ViewData.ModelState.IsValid))';                    
                if (isValid == 'true') {
                    var w = window.open();
                    $(w.document.body).html(jqXHR.responseText);
                }
                $("#imgSpinner1").hide();
            },
            beforeSend: function () { $("#imgSpinner1").show(); },
            complete: function () { $("#imgSpinner1").hide(); }
        });            
    });      

First get the position of the div element upto which u want to scroll by jQuery position() method.
Example : var pos = $("div").position();
Then get the y cordinates (height) of that element with ".top" method.
Example : pos.top;
Then get the x cordinates of the that div element with ".left" method.
These methods are originated from CSS positioning.
Once we get x & y cordinates, then we can use javascript's scrollTo(); method.
This method scrolls the document upto specific height & width.
It takes two parameters as x & y cordinates. Syntax : window.scrollTo(x,y);
Then just pass the x & y cordinates of the DIV element in the scrollTo() function.
Refer the example below ↓ ↓

<!DOCTYPE HTML>
    <html>
    <head>
        <title>
            Scroll upto Div with jQuery.
        </title>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
        <script>
            $(document).ready(function () {
                $("#button1").click(function () {
                    var x = $("#element").position(); //gets the position of the div element...
                    window.scrollTo(x.left, x.top); //window.scrollTo() scrolls the page upto certain position....
                    //it takes 2 parameters : (x axis cordinate, y axis cordinate);
                });
            });
            </script>
    </head>
    <body>
        <button id="button1">
            Click here to scroll
        </button>

        <div id="element" style="position:absolute;top:200%;left:0%;background-color:orange;height:100px;width:200px;">
            The DIV element.
            </div>
        </body>
    </html>

Use strpos and substr:

<?php

$longString = "I have a code snippet written in PHP that pulls a block of text.";
$truncated = substr($longString,0,strpos($longString,' ',30));

echo $truncated;

This will give you a string truncated at the first space after 30 characters.

For that purpose I have written a simple C program for that... It is in github...GitHub Link

Here how it works... First convert your double into a char string named s..

char s[50];
sprintf(s,"%.2f", yo);

Then use my dtype function to determine the type... My function will return a single character...You can use it like this...

char type=dtype(s);
//Return types are :
//i for integer
//f for float or decimals
//c for character...

Then you can use comparison to check it... That's it...

Bearer authentication in OpenAPI 3.0.0

OpenAPI 3.0 now supports Bearer/JWT authentication natively. It's defined like this:

openapi: 3.0.0
...

components:
  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: JWT  # optional, for documentation purposes only

security:
  - bearerAuth: []

This is supported in Swagger UI 3.4.0+ and Swagger Editor 3.1.12+ (again, for OpenAPI 3.0 specs only!).

UI will display the "Authorize" button, which you can click and enter the bearer token (just the token itself, without the "Bearer " prefix). After that, "try it out" requests will be sent with the Authorization: Bearer xxxxxx header.

Adding Authorization header programmatically (Swagger UI 3.x)

If you use Swagger UI and, for some reason, need to add the Authorization header programmatically instead of having the users click "Authorize" and enter the token, you can use the requestInterceptor. This solution is for Swagger UI 3.x; UI 2.x used a different technique.

// index.html

const ui = SwaggerUIBundle({
  url: "http://your.server.com/swagger.json",
  ...

  requestInterceptor: (req) => {
    req.headers.Authorization = "Bearer xxxxxxx"
    return req
  }
})

You might want to use Scanner to parse through and find the specific sections you want to modify. There's also Split and StringTokenizer that may work, but at the level you're working at Scanner might be what's needed.

Here's some additional info on what the difference is between them: Scanner vs. StringTokenizer vs. String.Split

I have found that from version 1.8.4 on, the libraries can be found in ~/Arduino/Libraries. Hope this helps anyone else.

I done this in a way like:

  @Html.RadioButtonFor(model => model.Gender, "M", false)@Html.Label("Male")
  @Html.RadioButtonFor(model => model.Gender, "F", false)@Html.Label("Female")

Use find()

$(this).find(".subclass").css("visibility","visible");

$ ruby -ne 'puts $_.scan(/id=(\d+)/)' file
9
10

I have done this without using any function.

$arr = array("1", "2", "3", "4", "5", "4", "2", "1");

$len = count($arr);
for ($i = 0; $i < $len; $i++) {
  $temp = $arr[$i];
  $j = $i;
  for ($k = 0; $k < $len; $k++) {
    if ($k != $j) {
      if ($temp == $arr[$k]) {
        echo $temp."<br>";
        $arr[$k]=" ";
      }
    }
  }
}

for ($i = 0; $i < $len; $i++) {
  echo $arr[$i] . " <br><br>";
}

A possible alternative approach in Excel 2010 or later versions:

AGGREGATE(6,6,A1,B1)

In AGGREGATE function the first 6 indicates PRODUCT operation and the second 6 denotes "ignore errors"

It is possible but, before git 2.9.3 (august 2016), a git push would print the full url used when pushing back to the cloned repo.
That would include your username and password!

But no more: See commit 68f3c07 (20 Jul 2016), and commit 882d49c (14 Jul 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 71076e1, 08 Aug 2016)}

push: anonymize URL in status output

Commit 47abd85 (fetch: Strip usernames from url's before storing them, 2009-04-17, Git 1.6.4) taught fetch to anonymize URLs.
The primary purpose there was to avoid sticking passwords in merge-commit messages, but as a side effect, we also avoid printing them to stderr.

The push side does not have the merge-commit problem, but it probably should avoid printing them to stderr. We can reuse the same anonymizing function.

Note that for this to come up, the credentials would have to appear either on the command line or in a git config file, neither of which is particularly secure.
So people should be switching to using credential helpers instead, which makes this problem go away.

But that's no excuse not to improve the situation for people who for whatever reason end up using credentials embedded in the URL.

Do not use some of the answers above.

Some suggest the use of nested SELECT, don't do that, it is excruciatingly slow. If you have lots of records to update, use join, so something like:

update (select bonus 
        from employee_bonus b 
        inner join employees e on b.employee_id = e.employee_id 
        where e.bonus_eligible = 'N') t
set t.bonus = 0;

See this link for more details. http://geekswithblogs.net/WillSmith/archive/2008/06/18/oracle-update-with-join-again.aspx.

Also, ensure that there are primary keys on all the tables you are joining.

You can use:

select * from your_table where upper(your_column) like '%ANGEL%'

Otherwise, you can use:

select * from your_table where upper(your_column) = 'ANGEL'

Which will be more efficient if you are looking for a match with no additional characters before or after your_column field as Gary Ray suggested in his comments.

Maybe you wrongly set permission on python3. For instance if for the file permission is set like

`os.chmod('spam.txt', 0777)` --> This will lead to SyntaxError 

This syntax was used in Python2. Now if you change like: os.chmod('spam.txt', 777) --> This is still worst!! Your permission will be set wrongly since are not on "octal" but on decimal.

Afterwards you will get permission Error if you try for instance to remove the file: PermissionError: [WinError 5] Access is denied:

Solution for python3 is quite easy: os.chmod('spam.txt', 0o777) --> The syntax is now ZERO and o "0o"

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

Copy a value from one row to any other qualified rows within the same table (or different tables):

UPDATE `your_table` t1, `your_table` t2
SET t1.your_field = t2.your_field
WHERE t1.other_field = some_condition
AND t1.another_field = another_condition
AND t2.source_id = 'explicit_value'

Start off by aliasing the table into 2 unique references so the SQL server can tell them apart

Next, specify the field(s) to copy.

Last, specify the conditions governing the selection of the rows

Depending on the conditions you may copy from a single row to a series, or you may copy a series to a series. You may also specify different tables, and you can even use sub-selects or joins to allow using other tables to control the relationships.

You can always refer to resources in your application directly by their JNDI name as configured in the container, but if you do so, essentially you are wiring the container-specific name into your code. This has some disadvantages, for example, if you'll ever want to change the name later for some reason, you'll need to update all the references in all your applications, and then rebuild and redeploy them.

<resource-ref> introduces another layer of indirection: you specify the name you want to use in the web.xml, and, depending on the container, provide a binding in a container-specific configuration file.

So here's what happens: let's say you want to lookup the java:comp/env/jdbc/primaryDB name. The container finds that web.xml has a <resource-ref> element for jdbc/primaryDB, so it will look into the container-specific configuration, that contains something similar to the following:

<resource-ref>
  <res-ref-name>jdbc/primaryDB</res-ref-name>
  <jndi-name>jdbc/PrimaryDBInTheContainer</jndi-name>
</resource-ref>

Finally, it returns the object registered under the name of jdbc/PrimaryDBInTheContainer.

The idea is that specifying resources in the web.xml has the advantage of separating the developer role from the deployer role. In other words, as a developer, you don't have to know what your required resources are actually called in production, and as the guy deploying the application, you will have a nice list of names to map to real resources.

String stringEncoded = URLEncoder.encode(
    "This text must be encoded! aeiou áéíóú ñ, peace!", "UTF-8");

While respond_to? will return true only for public methods, checking for "method definition" on a class may also pertain to private methods.

On Ruby v2.0+ checking both public and private sets can be achieved with

Foo.private_instance_methods.include?(:bar) || Foo.instance_methods.include?(:bar)

SELECT t1.cname, t1.wmname, t2.max
FROM makerar t1 JOIN (
    SELECT cname, MAX(avg) max
    FROM makerar
    GROUP BY cname ) t2
ON t1.cname = t2.cname AND t1.avg = t2.max;

Using rank() window function:

SELECT cname, wmname, avg
FROM (
    SELECT cname, wmname, avg, rank() 
    OVER (PARTITION BY cname ORDER BY avg DESC)
    FROM makerar) t
WHERE rank = 1;

Note

Either one will preserve multiple max values per group. If you want only single record per group even if there is more than one record with avg equal to max you should check @ypercube's answer.

Put it in a div tag seems to be the only way to FORCE that:

<div style="vertical-align: middle"><div><input ... /></div></div>

May be other tags like span works as like div do.

You can do some thing like this,

Initialize with empty array and assign the values later

String importRt = "23:43 43:34";
if(null != importRt) {
            importArray = Arrays.stream(importRt.split(" "))
                    .map(String::trim)
                    .toArray(String[]::new);
        }

System.out.println(Arrays.toString(exportImportArray));

Hope it helps..

If we see logically programming language and scripting language so this is 99.09% same . because we use same concept like loop , control condition ,variable and all so we can say yes both are same but there is only one thing is different between them that is in C/C++ and other programming language we compile the code before execution . but in the PHP , JavaScript and other scripting language we don't need to compile we directly execute in the browser.

I've made my own variation of Sevastyan's solution above

class HeaderItemDecoration(recyclerView: RecyclerView, private val listener: StickyHeaderInterface) : RecyclerView.ItemDecoration() {

private val headerContainer = FrameLayout(recyclerView.context)
private var stickyHeaderHeight: Int = 0
private var currentHeader: View? = null
private var currentHeaderPosition = 0

init {
    val layout = RelativeLayout(recyclerView.context)
    val params = recyclerView.layoutParams
    val parent = recyclerView.parent as ViewGroup
    val index = parent.indexOfChild(recyclerView)
    parent.addView(layout, index, params)
    parent.removeView(recyclerView)
    layout.addView(recyclerView, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)
    layout.addView(headerContainer, LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)
}

override fun onDrawOver(c: Canvas, parent: RecyclerView, state: RecyclerView.State) {
    super.onDrawOver(c, parent, state)

    val topChild = parent.getChildAt(0) ?: return

    val topChildPosition = parent.getChildAdapterPosition(topChild)
    if (topChildPosition == RecyclerView.NO_POSITION) {
        return
    }

    val currentHeader = getHeaderViewForItem(topChildPosition, parent)
    fixLayoutSize(parent, currentHeader)
    val contactPoint = currentHeader.bottom
    val childInContact = getChildInContact(parent, contactPoint) ?: return

    val nextPosition = parent.getChildAdapterPosition(childInContact)
    if (listener.isHeader(nextPosition)) {
        moveHeader(currentHeader, childInContact, topChildPosition, nextPosition)
        return
    }

    drawHeader(currentHeader, topChildPosition)
}

private fun getHeaderViewForItem(itemPosition: Int, parent: RecyclerView): View {
    val headerPosition = listener.getHeaderPositionForItem(itemPosition)
    val layoutResId = listener.getHeaderLayout(headerPosition)
    val header = LayoutInflater.from(parent.context).inflate(layoutResId, parent, false)
    listener.bindHeaderData(header, headerPosition)
    return header
}

private fun drawHeader(header: View, position: Int) {
    headerContainer.layoutParams.height = stickyHeaderHeight
    setCurrentHeader(header, position)
}

private fun moveHeader(currentHead: View, nextHead: View, currentPos: Int, nextPos: Int) {
    val marginTop = nextHead.top - currentHead.height
    if (currentHeaderPosition == nextPos && currentPos != nextPos) setCurrentHeader(currentHead, currentPos)

    val params = currentHeader?.layoutParams as? MarginLayoutParams ?: return
    params.setMargins(0, marginTop, 0, 0)
    currentHeader?.layoutParams = params

    headerContainer.layoutParams.height = stickyHeaderHeight + marginTop
}

private fun setCurrentHeader(header: View, position: Int) {
    currentHeader = header
    currentHeaderPosition = position
    headerContainer.removeAllViews()
    headerContainer.addView(currentHeader)
}

private fun getChildInContact(parent: RecyclerView, contactPoint: Int): View? =
        (0 until parent.childCount)
            .map { parent.getChildAt(it) }
            .firstOrNull { it.bottom > contactPoint && it.top <= contactPoint }

private fun fixLayoutSize(parent: ViewGroup, view: View) {

    val widthSpec = View.MeasureSpec.makeMeasureSpec(parent.width, View.MeasureSpec.EXACTLY)
    val heightSpec = View.MeasureSpec.makeMeasureSpec(parent.height, View.MeasureSpec.UNSPECIFIED)

    val childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
            parent.paddingLeft + parent.paddingRight,
            view.layoutParams.width)
    val childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
            parent.paddingTop + parent.paddingBottom,
            view.layoutParams.height)

    view.measure(childWidthSpec, childHeightSpec)

    stickyHeaderHeight = view.measuredHeight
    view.layout(0, 0, view.measuredWidth, stickyHeaderHeight)
}

interface StickyHeaderInterface {

    fun getHeaderPositionForItem(itemPosition: Int): Int

    fun getHeaderLayout(headerPosition: Int): Int

    fun bindHeaderData(header: View, headerPosition: Int)

    fun isHeader(itemPosition: Int): Boolean
}
}

... and here is implementation of StickyHeaderInterface (I did it directly in recycler adapter):

override fun getHeaderPositionForItem(itemPosition: Int): Int =
    (itemPosition downTo 0)
        .map { Pair(isHeader(it), it) }
        .firstOrNull { it.first }?.second ?: RecyclerView.NO_POSITION

override fun getHeaderLayout(headerPosition: Int): Int {
    /* ... 
      return something like R.layout.view_header
      or add conditions if you have different headers on different positions
    ... */
}

override fun bindHeaderData(header: View, headerPosition: Int) {
    if (headerPosition == RecyclerView.NO_POSITION) header.layoutParams.height = 0
    else /* ...
      here you get your header and can change some data on it
    ... */
}

override fun isHeader(itemPosition: Int): Boolean {
    /* ...
      here have to be condition for checking - is item on this position header
    ... */
}

So, in this case header is not just drawing on canvas, but view with selector or ripple, clicklistener, etc.

If you are using ContentProvider then you can use:

Cursor cursor = getContentResolver().query(CONTENT_URI, new String[] {"count(*)"},
            uname=" + loginname + " and pwd=" + loginpass, null, null);
    cursor.moveToFirst();
    int count = cursor.getInt(0);

Move pod members to a base class to shorten your initializer list:

struct foo_pod
{
    int x;
    int y;
    int z;
};

struct foo : foo_pod
{
    std::string name;
    foo(std::string name)
        : foo_pod()
        , name(name)
    {
    }
};

int main()
{
    foo f("bar");
    printf("%d %d %d %s\n", f.x, f.y, f.z, f.name.c_str());
}

I needed a solution where the strings to be replaced can be a regular expressions, for example to help in normalizing a long text by replacing multiple whitespace characters with a single one. Building on a chain of answers from others, including MiniQuark and mmj, this is what I came up with:

def multiple_replace(string, reps, re_flags = 0):
    """ Transforms string, replacing keys from re_str_dict with values.
    reps: dictionary, or list of key-value pairs (to enforce ordering;
          earlier items have higher priority).
          Keys are used as regular expressions.
    re_flags: interpretation of regular expressions, such as re.DOTALL
    """
    if isinstance(reps, dict):
        reps = reps.items()
    pattern = re.compile("|".join("(?P<_%d>%s)" % (i, re_str[0])
                                  for i, re_str in enumerate(reps)),
                         re_flags)
    return pattern.sub(lambda x: reps[int(x.lastgroup[1:])][1], string)

It works for the examples given in other answers, for example:

>>> multiple_replace("(condition1) and --condition2--",
...                  {"condition1": "", "condition2": "text"})
'() and --text--'

>>> multiple_replace('hello, world', {'hello' : 'goodbye', 'world' : 'earth'})
'goodbye, earth'

>>> multiple_replace("Do you like cafe? No, I prefer tea.",
...                  {'cafe': 'tea', 'tea': 'cafe', 'like': 'prefer'})
'Do you prefer tea? No, I prefer cafe.'

The main thing for me is that you can use regular expressions as well, for example to replace whole words only, or to normalize white space:

>>> s = "I don't want to change this name:\n  Philip II of Spain"
>>> re_str_dict = {r'\bI\b': 'You', r'[\n\t ]+': ' '}
>>> multiple_replace(s, re_str_dict)
"You don't want to change this name: Philip II of Spain"

If you want to use the dictionary keys as normal strings, you can escape those before calling multiple_replace using e.g. this function:

def escape_keys(d):
    """ transform dictionary d by applying re.escape to the keys """
    return dict((re.escape(k), v) for k, v in d.items())

>>> multiple_replace(s, escape_keys(re_str_dict))
"I don't want to change this name:\n  Philip II of Spain"

The following function can help in finding erroneous regular expressions among your dictionary keys (since the error message from multiple_replace isn't very telling):

def check_re_list(re_list):
    """ Checks if each regular expression in list is well-formed. """
    for i, e in enumerate(re_list):
        try:
            re.compile(e)
        except (TypeError, re.error):
            print("Invalid regular expression string "
                  "at position {}: '{}'".format(i, e))

>>> check_re_list(re_str_dict.keys())

Note that it does not chain the replacements, instead performs them simultaneously. This makes it more efficient without constraining what it can do. To mimic the effect of chaining, you may just need to add more string-replacement pairs and ensure the expected ordering of the pairs:

>>> multiple_replace("button", {"but": "mut", "mutton": "lamb"})
'mutton'
>>> multiple_replace("button", [("button", "lamb"),
...                             ("but", "mut"), ("mutton", "lamb")])
'lamb'

I'm sorry, bu it's not posible, unless you made a backup file earlier.

EDIT: Actually it is possible, but it gets very tricky and you shouldn't think about it if data wasn't really, really important. You see: when data get's deleted from a computer it still remains in the same place on the disk, only its sectors are marked as empty. So data remains intact, except if it gets overwritten by new data. There are several programs designed for this purpose and there are companies who specialize in data recovery, though they are rather expensive.

As a continuation on Matas' answer on benchmarking.

TL/DR: Exists() and Any() are equally fast.

First off: Benchmarking using Stopwatch is not precise (see series0ne's answer on a different, but similiar, topic), but it is far more precise than DateTime.

The way to get really precise readings is by using Performance Profiling. But one way to get a sense of how the two methods' performance measure up to each other is by executing both methods loads of times and then comparing the fastest execution time of each. That way, it really doesn't matter that JITing and other noise gives us bad readings (and it does), because both executions are "equally misguiding" in a sense.

static void Main(string[] args)
    {
        Console.WriteLine("Generating list...");
        List<string> list = GenerateTestList(1000000);
        var s = string.Empty;

        Stopwatch sw;
        Stopwatch sw2;
        List<long> existsTimes = new List<long>();
        List<long> anyTimes = new List<long>();

        Console.WriteLine("Executing...");
        for (int j = 0; j < 1000; j++)
        {
            sw = Stopwatch.StartNew();
            if (!list.Exists(o => o == "0123456789012"))
            {
                sw.Stop();
                existsTimes.Add(sw.ElapsedTicks);
            }
        }

        for (int j = 0; j < 1000; j++)
        {
            sw2 = Stopwatch.StartNew();
            if (!list.Exists(o => o == "0123456789012"))
            {
                sw2.Stop();
                anyTimes.Add(sw2.ElapsedTicks);
            }
        }

        long existsFastest = existsTimes.Min();
        long anyFastest = anyTimes.Min();

        Console.WriteLine(string.Format("Fastest Exists() execution: {0} ticks\nFastest Any() execution: {1} ticks", existsFastest.ToString(), anyFastest.ToString()));
        Console.WriteLine("Benchmark finished. Press any key.");
        Console.ReadKey();
    }

    public static List<string> GenerateTestList(int count)
    {
        var list = new List<string>();
        for (int i = 0; i < count; i++)
        {
            Random r = new Random();
            int it = r.Next(0, 100);
            list.Add(new string('s', it));
        }
        return list;
    }

After executing the above code 4 times (which in turn do 1 000 Exists() and Any() on a list with 1 000 000 elements), it's not hard to see that the methods are pretty much equally fast.

Fastest Exists() execution: 57881 ticks
Fastest Any() execution: 58272 ticks

Fastest Exists() execution: 58133 ticks
Fastest Any() execution: 58063 ticks

Fastest Exists() execution: 58482 ticks
Fastest Any() execution: 58982 ticks

Fastest Exists() execution: 57121 ticks
Fastest Any() execution: 57317 ticks

There is a slight difference, but it's too small a difference to not be explained by background noise. My guess would be that if one would do 10 000 or 100 000 Exists() and Any() instead, that slight difference would disappear more or less.

This is a recursive algorithm to sort by multiple fields while having the chance to format values before comparison.

var data = [
{
    "id": 1,
    "ship": null,
    "product": "Orange",
    "quantity": 7,
    "price": 92.08,
    "discount": 0
},
{
    "id": 2,
    "ship": "2017-06-14T23:00:00.000Z".toDate(),
    "product": "Apple",
    "quantity": 22,
    "price": 184.16,
    "discount": 0
},
...
]
var sorts = ["product", "quantity", "ship"]

// comp_val formats values and protects against comparing nulls/undefines
// type() just returns the variable constructor
// String.lower just converts the string to lowercase.
// String.toDate custom fn to convert strings to Date
function comp_val(value){
    if (value==null || value==undefined) return null
    var cls = type(value)
    switch (cls){
        case String:
            return value.lower()
    }
    return value
}

function compare(a, b, i){
    i = i || 0
    var prop = sorts[i]
    var va = comp_val(a[prop])
    var vb = comp_val(b[prop])

    // handle what to do when both or any values are null
    if (va == null || vb == null) return true

    if ((i < sorts.length-1) && (va == vb)) {
        return compare(a, b, i+1)
    } 
    return va > vb
}

var d = data.sort(compare);
console.log(d);

If a and b are equal it will just try the next field until none is available.

Using dialog methods:

$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');

Or directly, hacky though:

$("span.ui-dialog-title").text('My New Title'); 

For future reference, you can skip google with jQuery. The jQuery API will answer your questions most of the time. In this case, the Dialog API page. For the main library: http://api.jquery.com

Not that I know of, but what you could do is loop through the first 31 lines doing nothing using the readline() function of BufferedReader

FileInputStream fs= new FileInputStream("someFile.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(fs));
for(int i = 0; i < 31; ++i)
  br.readLine();
String lineIWant = br.readLine();

with open('D:\\file.txt', 'r') as f1:
    lines = f1.readlines()
lines = [s[:-1] for s in lines]

Here is another way :

var currentMonth = 1
var months = ["ENE", "FEB", "MAR", "APR", "MAY", "JUN", 
              "JUL", "AGO", "SEP", "OCT", "NOV", "DIC"];

console.log(months[currentMonth - 1]);

use DBName

select * from TABLE_NAME A

where A.date >= '2018-06-26 21:24' and A.date <= '2018-06-26 21:28';

The bit shift operators are more efficient as compared to the / or * operators.

In computer architecture, divide(/) or multiply(*) take more than one time unit and register to compute result, while, bit shift operator, is just one one register and one time unit computation.

In January 2004, I was contacted by Philips New Display Technologies who were creating the electronics for the first ever commercial e-ink, the Sony Librie, who had only been released in Japan, years before Amazon Kindle and the others hit the market in US an Europe.

The Philips engineers had a major problem. A few months before the product was supposed to hit the market, they were still getting ghosting on the screen when changing pages. The problem was the 200 drivers that were creating the electrostatic field. Each of these drivers had a certain voltage that had to be set right between zero and 1000 mV or something like this. But if you changed one of them, it would change everything.

So optimizing each driver's voltage individually was out of the question. The number of possible combination of values was in billions,and it took about 1 minute for a special camera to evaluate a single combination. The engineers had tried many standard optimization techniques, but nothing would come close.

The head engineer contacted me because I had previously released a Genetic Programming library to the open-source community. He asked if GP/GA's would help and if I could get involved. I did, and for about a month we worked together, me writing and tuning the GA library, on synthetic data, and him integrating it into their system. Then, one weekend they let it run live with the real thing.

The following Monday I got these glowing emails from him and their hardware designer, about how nobody could believe the amazing results the GA found. This was it. Later that year the product hit the market.

I didn't get paid one cent for it, but I got 'bragging' rights. They said from the beginning they were already over budget, so I knew what the deal was before I started working on it. And it's a great story for applications of GAs. :)

Try something like this:

#include <signal.h>

pid_t child_pid = -1 ; //Global

void kill_child(int sig)
{
    kill(child_pid,SIGKILL);
}

int main(int argc, char *argv[])
{
    signal(SIGALRM,(void (*)(int))kill_child);
    child_pid = fork();
    if (child_pid > 0) {
     /*PARENT*/
        alarm(30);
        /*
         * Do parent's tasks here.
         */
        wait(NULL);
    }
    else if (child_pid == 0){
     /*CHILD*/
        /*
         * Do child's tasks here.
         */
    }
}

A bit shorter, at least:

wanted_keys = ['l', 'm', 'n'] # The keys you want
dict((k, bigdict[k]) for k in wanted_keys if k in bigdict)

Here's one way:

Stream myStream = null;
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = theDialog.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}

                employee = new Employee();
                currEmployeeLine = 1;
            }

            else
            {

            switch (currEmployeeLine)
            {
                case 1:

                    string[] splitLines = filelines[a].Split(' ');

                    employee.Wage = Convert.ToDouble(splitLines[0].Trim());
                    employee.Hours = Convert.ToDouble(splitLines[1].Trim());
                    break;


            }

        }
        //Test to see if it works
        foreach (Employee emp in employeeList)
        {
            MessageBox.Show(emp.EmployeeNum + Environment.NewLine +
                emp.Name + Environment.NewLine +
                emp.Address + Environment.NewLine +
                emp.Wage + Environment.NewLine +

        }
    }
}

Most drivers support forward only resultset - so method like last, beforeFirst etc are not supported.

The first approach is suitable if you are also getting the data in the same loop - otherwise the resultSet has already been iterated and can not be used again.

In most cases the requirement is to get the number of rows a query would return without fetching the rows. Iterating through the result set to find the row count is almost same as processing the data. It is better to do another count(*) query instead.

If you already have onChange handler for the individual FieldEditors I don't see why you couldn't just move the state up to the FormEditor component and just pass down a callback from there to the FieldEditors that will update the parent state. That seems like a more React-y way to do it, to me.

Something along the line of this perhaps:

const FieldEditor = ({ value, onChange, id }) => {
  const handleChange = event => {
    const text = event.target.value;
    onChange(id, text);
  };

  return (
    <div className="field-editor">
      <input onChange={handleChange} value={value} />
    </div>
  );
};

const FormEditor = props => {
  const [values, setValues] = useState({});
  const handleFieldChange = (fieldId, value) => {
    setValues({ ...values, [fieldId]: value });
  };

  const fields = props.fields.map(field => (
    <FieldEditor
      key={field}
      id={field}
      onChange={handleFieldChange}
      value={values[field]}
    />
  ));

  return (
    <div>
      {fields}
      <pre>{JSON.stringify(values, null, 2)}</pre>
    </div>
  );
};

// To add abillity to dynamically add/remove fields keep the list in state
const App = () => {
  const fields = ["field1", "field2", "anotherField"];

  return <FormEditor fields={fields} />;
};

You can do very ugly stuff in python like:

def o(s):return''.join([chr(ord(n)+(13if'Z'<n<'n'or'N'>n else-13))if n.isalpha()else n for n in s])

which is function for rot13/cesa encryption in one line with 99 characters.

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

The solution below has a "SEO friendlier" version:

function hyphenize($string) {
    $dict = array(
        "I'm"      => "I am",
        "thier"    => "their",
        // Add your own replacements here
    );
    return strtolower(
        preg_replace(
          array( '#[\\s-]+#', '#[^A-Za-z0-9. -]+#' ),
          array( '-', '' ),
          // the full cleanString() can be downloaded from http://www.unexpectedit.com/php/php-clean-string-of-utf8-chars-convert-to-similar-ascii-char
          cleanString(
              str_replace( // preg_replace can be used to support more complicated replacements
                  array_keys($dict),
                  array_values($dict),
                  urldecode($string)
              )
          )
        )
    );
}

function cleanString($text) {
    $utf8 = array(
        '/[áàâãªä]/u'   =>   'a',
        '/[ÁÀÂÃÄ]/u'    =>   'A',
        '/[ÍÌÎÏ]/u'     =>   'I',
        '/[íìîï]/u'     =>   'i',
        '/[éèêë]/u'     =>   'e',
        '/[ÉÈÊË]/u'     =>   'E',
        '/[óòôõºö]/u'   =>   'o',
        '/[ÓÒÔÕÖ]/u'    =>   'O',
        '/[úùûü]/u'     =>   'u',
        '/[ÚÙÛÜ]/u'     =>   'U',
        '/ç/'           =>   'c',
        '/Ç/'           =>   'C',

        '/[’‘‹›‚]/u'    =>   ' ', // Literally a single quote
        '/[“”«»„]/u'    =>   ' ', // Double quote
        '/ /'           =>   ' ', // nonbreaking space (equiv. to 0x160)
    );
    return preg_replace(array_keys($utf8), array_values($utf8), $text);
}

The rationale for the above functions (which I find way inefficient - the one below is better) is that a service that shall not be named apparently ran spelling checks and keyword recognition on the URLs.

After losing a long time on a customer's paranoias, I found out they were not imagining things after all -- their SEO experts [I am definitely not one] reported that, say, converting "Viaggi Economy Perù" to viaggi-economy-peru "behaved better" than viaggi-economy-per (the previous "cleaning" removed UTF8 characters; Bogotà became bogot, Medellìn became medelln and so on).

There were also some common misspellings that seemed to influence the results, and the only explanation that made sense to me is that our URL were being unpacked, the words singled out, and used to drive God knows what ranking algorithms. And those algorithms apparently had been fed with UTF8-cleaned strings, so that "Perù" became "Peru" instead of "Per". "Per" did not match and sort of took it in the neck.

In order to both keep UTF8 characters and replace some misspellings, the faster function below became the more accurate (?) function above. $dict needs to be hand tailored, of course.

Previous answer

A simple approach:

// Remove all characters except A-Z, a-z, 0-9, dots, hyphens and spaces
// Note that the hyphen must go last not to be confused with a range (A-Z)
// and the dot, NOT being special (I know. My life was a lie), is NOT escaped

$str = preg_replace('/[^A-Za-z0-9. -]/', '', $str);

// Replace sequences of spaces with hyphen
$str = preg_replace('/  */', '-', $str);

// The above means "a space, followed by a space repeated zero or more times"
// (should be equivalent to / +/)

// You may also want to try this alternative:
$str = preg_replace('/\\s+/', '-', $str);

// where \s+ means "zero or more whitespaces" (a space is not necessarily the
// same as a whitespace) just to be sure and include everything

Note that you might have to first urldecode() the URL, since %20 and + both are actually spaces - I mean, if you have "Never%20gonna%20give%20you%20up" you want it to become Never-gonna-give-you-up, not Never20gonna20give20you20up . You might not need it, but I thought I'd mention the possibility.

So the finished function along with test cases:

function hyphenize($string) {
    return 
    ## strtolower(
          preg_replace(
            array('#[\\s-]+#', '#[^A-Za-z0-9. -]+#'),
            array('-', ''),
        ##     cleanString(
              urldecode($string)
        ##     )
        )
    ## )
    ;
}

print implode("\n", array_map(
    function($s) {
            return $s . ' becomes ' . hyphenize($s);
    },
    array(
    'Never%20gonna%20give%20you%20up',
    "I'm not the man I was",
    "'Légeresse', dit sa majesté",
    )));


Never%20gonna%20give%20you%20up    becomes  never-gonna-give-you-up
I'm not the man I was              becomes  im-not-the-man-I-was
'Légeresse', dit sa majesté        becomes  legeresse-dit-sa-majeste

To handle UTF-8 I used a cleanString implementation found online (link broken since, but a stripped down copy with all the not-too-esoteric UTF8 characters is at the beginning of the answer; it's also easy to add more characters to it if you need) that converts UTF8 characters to normal characters, thus preserving the word "look" as much as possible. It could be simplified and wrapped inside the function here for performance.

The function above also implements converting to lowercase - but that's a taste. The code to do so has been commented out.

I have stuck in this issue for a while and I have came to the following solution

1. Create an ApplicationContextAware class (which is a class that implements the ApplicationContextAware)

2. In ApplicationContextAware we have to implement the one method only

   public void setApplicationContext(ApplicationContext context) throws BeansException

3. Tell the spring context about this new bean (I call it SpringContext)

   bean id="springContext" class="packe.of.SpringContext" />
   

Here is the code snippet

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class SpringContext implements ApplicationContextAware {
  private static ApplicationContext context;

  @Override
  public void setApplicationContext(ApplicationContext context) throws BeansException {
    this.context = context;
  }
  public static ApplicationContext getApplicationContext() {
    return context;
  }
}

4. Then you can call any method of application context outside the spring context for example

   
   SomeServiceClassOrComponent utilityService SpringContext.getApplicationContext().getBean(SomeServiceClassOrComponent .class);
   

I hope this will solve the problem for many users

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_profile, container, false);
    notification = (ImageView)v.findViewById(R.id.notification);

    notification.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FragmentTransaction fr = getFragmentManager().beginTransaction();
            fr.replace(R.id.container,new NotificationFragment());
            fr.commit();
        }
    });

    return v;
}

If anyone missed it out in the comments, try this:

dataframe[column].value_counts().to_frame()

Try casting to List in the extension method before running the loop. That way you can take advantage of the performance of List.AddRange.

public static void AddRange<T>(this ICollection<T> destination,
                               IEnumerable<T> source)
{
    List<T> list = destination as List<T>;

    if (list != null)
    {
        list.AddRange(source);
    }
    else
    {
        foreach (T item in source)
        {
            destination.Add(item);
        }
    }
}

There you go, this is what I used to fix your problem:

CSS CODE

nav ul { list-style-type: none; }

HTML CODE

<nav>
<ul>
<li><a href="#">Milk</a>
   <ul>
   <li><a href="#">Goat</a></li>
   <li><a href="#">Cow</a></li>
   </ul>
</li>
<li><a href="#">Eggs</a>
   <ul>
   <li><a href="#">Free-range</a></li>
   <li><a href="#">Other</a></li>
   </ul>
</li>
<li><a href="#">Cheese</a>
   <ul>
   <li><a href="#">Smelly</a></li>
   <li><a href="#">Extra smelly</a></li>
   </ul>
</li>
</ul>
</nav>

Internet Explorer 9 and lower : You could use conditional comments to load an IE-specific stylesheet for any version (or combination of versions) that you wanted to specifically target.like below using external stylesheet.

<!--[if IE]>
  <link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->

However, beginning in version 10, conditional comments are no longer supported in IE.

Internet Explorer 10 & 11 : Create a media query using -ms-high-contrast, in which you place your IE 10 and 11-specific CSS styles. Because -ms-high-contrast is Microsoft-specific (and only available in IE 10+), it will only be parsed in Internet Explorer 10 and greater.

@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
     /* IE10+ CSS styles go here */
}

Microsoft Edge 12 : Can use the @supports rule Here is a link with all the info about this rule

@supports (-ms-accelerator:true) {
  /* IE Edge 12+ CSS styles go here */ 
}

Inline rule IE8 detection

I have 1 more option but it is only detect IE8 and below version.

  /* For IE css hack */
  margin-top: 10px\9 /* apply to all ie from 8 and below */
  *margin-top:10px;  /* apply to ie 7 and below */
  _margin-top:10px; /* apply to ie 6 and below */

As you specefied for embeded stylesheet. I think you need to use media query and condition comment for below version.

am assuming custom_class to be your class to override heading color of the panel. just add !important to it or add inline styles or a id and add styles as they will have more specificity over class added styles.

• with !important

  .custom_class{ background-color: red !important; }

• with !important

• with ID :

  #custom_id{ background-color: red; }

-with inline styles :

<div id="custom_id" class="panel panel-default">
      <div class="panel-heading custom_class" style="background-color:red">
      </div>
    </div>

In the above query when we are trying to combine two or more tables it is necessary to use joins and specify the alias name for description and date (that means, the table from which you are fetching the description and date values)

SELECT DISTINCT Description, Date as treatmentDate  
FROM doothey.Patient P  
INNER JOIN doothey.Account A ON P.PatientID = A.PatientID  
INNER JOIN doothey.AccountLine AL ON A.AccountNo = AL.AccountNo  
INNER JOIN doothey.Item I ON AL.ItemNo = I.ItemNo  
WHERE p.FamilyName = 'Stange' AND p.GivenName = 'Jessie';

I only had progress on this issue after a "/etc/init.d/jenkins force-reload". I recommend trying that before anything else, and using that rather than restart.

The way you can do this is by:

• turning your select query into a view
• right click on the view and choose Edit All Rows (you will get a grid of values you can edit - even if the values are from different tables).

You can also add Insert/Update triggers to your view that will allow you to grab the values from your view fields and then use T-SQL to manage updates to multiple tables.

Selenium Web Driver Handling Frames
It is impossible to click iframe directly through XPath since it is an iframe. First we have to switch to the frame and then we can click using xpath.

driver.switchTo().frame() has multiple overloads.

1. driver.switchTo().frame(name_or_id)
   Here your iframe doesn't have id or name, so not for you.

2. driver.switchTo().frame(index)
   This is the last option to choose, because using index is not stable enough as you could imagine. If this is your only iframe in the page, try driver.switchTo().frame(0)

3. driver.switchTo().frame(iframe_element)
   The most common one. You locate your iframe like other elements, then pass it into the method.

driver.switchTo().defaultContent(); [parentFrame, defaultContent, frame]

// Based on index position:
int frameIndex = 0;
List<WebElement> listFrames = driver.findElements(By.tagName("iframe"));
System.out.println("list frames   "+listFrames.size());
driver.switchTo().frame(listFrames.get( frameIndex ));

// XPath|CssPath Element:
WebElement frameCSSPath = driver.findElement(By.cssSelector("iframe[title='Fill Quote']"));
WebElement frameXPath = driver.findElement(By.xpath(".//iframe[1]"));
WebElement frameTag = driver.findElement(By.tagName("iframe"));

driver.switchTo().frame( frameCSSPath ); // frameXPath, frameTag


driver.switchTo().frame("relative=up"); // focus to parent frame.
driver.switchTo().defaultContent(); // move to the most parent or main frame

// For alert's
Alert alert = driver.switchTo().alert(); // Switch to alert pop-up
alert.accept();
alert.dismiss();

XML Test:

<html>
    <IFame id='1'>...       parentFrame() « context remains unchanged. <IFame1>

I prefer to use mutex mechanism in such cases, but if you really want to use boolean, then you should declare it as volatile (to provide the change visibility across threads) and just run the body-less cycle with that boolean as a condition :

//.....some class

volatile boolean someBoolean; 

Thread someThread = new Thread() {

    @Override 
    public void run() {
        //some actions
        while (!someBoolean); //wait for condition 
        //some actions 
    }

};

Your server process has received a SIGPIPE writing to a socket. This usually happens when you write to a socket fully closed on the other (client) side. This might be happening when a client program doesn't wait till all the data from the server is received and simply closes a socket (using close function).

In a C program you would normally try setting to ignore SIGPIPE signal or setting a dummy signal handler for it. In this case a simple error will be returned when writing to a closed socket. In your case a python seems to throw an exception that can be handled as a premature disconnect of the client.

Old thread, but I came up with a solution that I believe is cleaner since it does not disable every even bound to the object, and only prevent random and unwanted text selections on the page. It is straightforward, and works well for me. Here is an example; I want to prevent text-selection when I click several time on the object with the class "arrow-right":

$(".arrow-right").hover(function(){$('body').css({userSelect: "none"});}, function(){$('body').css({userSelect: "auto"});});

HTH !

PHP 7.4+; with the null coalescing assignment operator

$var ??= '';

PHP 7.0+; with the null coalescing operator

$var = $var ?? '';

PHP 5.3+; with the ternary operator shorthand

isset($var) ?: $var = '';

Or for all/older versions with isset:

$var = isset($var) ? $var : '';

or

!isset($var) && $var = '';

It's not possible with a "normal" object, but you can do it with an ExpandoObject and the dynamic keyword:

dynamic person = new ExpandoObject();
person.FirstName = "Sam";
person.LastName = "Lewis";
person.Age = 42;
person.Foo = "Bar";
...

If you try to assign a property that doesn't exist, it is added to the object. If you try to read a property that doesn't exist, it will raise an exception. So it's roughly the same behavior as a dictionary (and ExpandoObject actually implements IDictionary<string, object>)

Here's a rotation generator which doesn't need to make a warped copy of the input sequence ... may be useful if the input sequence is much larger than 7 items.

>>> def rotated_sequence(seq, start_index):
...     n = len(seq)
...     for i in xrange(n):
...         yield seq[(i + start_index) % n]
...
>>> s = 'su m tu w th f sa'.split()
>>> list(rotated_sequence(s, s.index('m')))
['m', 'tu', 'w', 'th', 'f', 'sa', 'su']
>>>

Although it does not answer the question directly, one way to scale images is relative to the size (especially width) of the viewport, which is mostly the use case for responsive design. No wrapper elements needed.

img {
    width: 50vw;
}

<img src="" />

Use the map-function instead. It transforms the value inside the optional.

Like this:

private String getStringIfObjectIsPresent(Optional<Object> object) {
    return object.map(() -> {
        String result = "result";
        //some logic with result and return it
        return result;
    }).orElseThrow(MyCustomException::new);
}

You can add image to asp.net button. you dont need to use only image button or link button. When displaying button on browser, it is converting to html button as default. So you can use its "Style" properties for adding image. My example is below. I hope it works for you.

Style="background-image:url('Image/1.png');"

You can change image location with using

background-repeat

properties. So you can write a button like below:

<asp:Button ID="btnLogin" runat="server" Text="Login" Style="background-image:url('Image/1.png'); background-repeat:no-repeat"/>

I can't guarantee it's the simplest, but I like MarkerWithLabel. As shown in the basic example, CSS styles define the label's appearance and options in the JavaScript define the content and placement.

 .labels {
   color: red;
   background-color: white;
   font-family: "Lucida Grande", "Arial", sans-serif;
   font-size: 10px;
   font-weight: bold;
   text-align: center;
   width: 60px;     
   border: 2px solid black;
   white-space: nowrap;
 }

JavaScript:

 var marker = new MarkerWithLabel({
   position: homeLatLng,
   draggable: true,
   map: map,
   labelContent: "$425K",
   labelAnchor: new google.maps.Point(22, 0),
   labelClass: "labels", // the CSS class for the label
   labelStyle: {opacity: 0.75}
 });

The only part that may be confusing is the labelAnchor. By default, the label's top left corner will line up to the marker pushpin's endpoint. Setting the labelAnchor's x-value to half the width defined in the CSS width property will center the label. You can make the label float above the marker pushpin with an anchor point like new google.maps.Point(22, 50).

In case access to the links above are blocked, I copied and pasted the packed source of MarkerWithLabel into this JSFiddle demo. I hope JSFiddle is allowed in China :|

In this day and age of mouse driven computers and tablets with touch screens etc, it is often forgotten to cater for input via keyboard only. A button should support a focus rectangle (the dotted rectangle when the button has focus) or another shape matching the button shape.

To add a focus rectangle to the button, use this XAML (from this site). Focus rectangle style:

<Style x:Key="ButtonFocusVisual">
  <Setter Property="Control.Template">
    <Setter.Value>
      <ControlTemplate>
        <Border>
          <Rectangle Margin="2" StrokeThickness="1" Stroke="#60000000" StrokeDashArray="1 2" />
        </Border>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

Applying the style to the button:

<Style TargetType="Button">
  <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}" />
  ...

Create a new file called files.txt and paste the URLs one per line. Then run the following command.

xargs -n 1 curl -O < files.txt

As You're getting values from textfield as jTextField3.getText();.

As it is a textField it will return you string format as its format says:

String getText()

      Returns the text contained in this TextComponent.

So, convert your String to Integer as:

int jml = Integer.parseInt(jTextField3.getText());

instead of directly setting

   int jml = jTextField3.getText();

Using the Split function seems more elegant than InStr and Left, in my opinion.

Private Sub CommandButton2_Click()


Dim ThisFileName As String
Dim BaseFileName As String

Dim FileNameArray() As String

ThisFileName = ThisWorkbook.Name
FileNameArray = Split(ThisFileName, ".")
BaseFileName = FileNameArray(0)

Using Chrome, searching for the images files in links (as proposed previously) didn't work as it is generating something like:

(...) i18nTemplate.process(document, loadTimeData);
</script>
<script>start("current directory...")</script>
<script>addRow("..","..",1,"170 B","10/2/15, 8:32:45 PM");</script>
<script>addRow("fotos-interessantes-11.jpg","fotos-interessantes-> 11.jpg",false,"","");</script>

I wanted to share this because I spent a long time searching for an easy way to implement this in a java program I'm working on. This doesn't quite give the output you're looking for but its close. The function in mysql called GROUP_CONCAT() worked really well for specifying how many results to return in each group. Using LIMIT or any of the other fancy ways of trying to do this with COUNT didn't work for me. So if you're willing to accept a modified output, its a great solution. Lets say I have a table called 'student' with student ids, their gender, and gpa. Lets say I want to top 5 gpas for each gender. Then I can write the query like this

SELECT sex, SUBSTRING_INDEX(GROUP_CONCAT(cast(gpa AS char ) ORDER BY gpa desc), ',',5) 
AS subcategories FROM student GROUP BY sex;

Note that the parameter '5' tells it how many entries to concatenate into each row

And the output would look something like

+--------+----------------+
| Male   | 4,4,4,4,3.9    |
| Female | 4,4,3.9,3.9,3.8|
+--------+----------------+

You can also change the ORDER BY variable and order them a different way. So if I had the student's age I could replace the 'gpa desc' with 'age desc' and it will work! You can also add variables to the group by statement to get more columns in the output. So this is just a way I found that is pretty flexible and works good if you are ok with just listing results.

var myregexp = new RegExp(/ {2,}/g);

str = str.replace(myregexp,' ');

Since you have not mentioned what needs to be copied, I have left that section empty in the code below.

Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.

This will get you started. I have commented the code so that you will not face any problem understanding it.

First paste the below mentioned code in the outlook module.

Then

1. Click on Tools~~>Rules and Alerts
2. Click on "New Rule"
3. Click on "start from a blank rule"
4. Select "Check messages When they arrive"
5. Under conditions, click on "with specific words in the subject"
6. Click on "specific words" under rules description.
7. Type the word that you want to check in the dialog box that pops up and click on "add".
8. Click "Ok" and click next
9. Select "move it to specified folder" and also select "run a script" in the same box
10. In the box below, specify the specific folder and also the script (the macro that you have in module) to run.
11. Click on finish and you are done.

When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

FOLLOWUP

To extract the contents from your email body, you can split it using SPLIT() and then parsing out the relevant information from it. See this example

Dim MyAr() As String

MyAr = Split(olMail.body, vbCrLf)

For i = LBound(MyAr) To UBound(MyAr)
    '~~> This will give you the contents of your email
    '~~> on separate lines
    Debug.Print MyAr(i)
Next i

Try this:

$NameRegex = "chalmw-dm"  
$NameR = "$($NameRegex)*"
Get-ADComputer -Filter {name -like $NameR -and Enabled -eq $True}

you can pass it this way :

Url.Action("CreatePerson", "Person", new RouteValueDictionary(new { id = id }));

OR can also pass this way

Url.Action("CreatePerson", "Person", new { id = id });

I also ran into this problem last week and have managed to fix this now. I got the idea to resolve this one from the response shared by @gukoff.

My requirement and situation was slightly different from the ones shared so far but the issue was fundamentally the same so I thought of sharing it on this thread.

I was actually trying to query zookeeper quorum (after every 30 seconds) for some information from my application and was using the Curator Framework for this purpose (the methods available in LeaderLatch class). So, essentially I was starting up a CuratorFramework client and supplying this to LeaderLatch object.

Only after I ran into the error mentioned in this thread - I realised that I did not close the zookeeper client connection(s) established in my applications. The maxClientCnxns property had the value of 60 and as soon as the number of connections (all of them were stale connections) touched 60, my application started complaining with this error.

I found out about the number of open connections by:

1. Checking the zookeeper logs, where there were warning messages stating "Too many connections from {IP address of the host}"

2. Running the following netstat command from the same host mentioned in the above logs where my application was running:

netstat -no | grep :2181 | wc -l

Note: The 2181 port is the default for zookeeper supplied as a parameter in grep to match the zookeeper connections.

To fix this, I cleared up all of those stale connections manually and then added the code for closing the zookeeper client connections gracefully in my application.

I hope this helps!

Django-model-values (disclosure: author) provides an implementation of the NotEqual lookup, as in this answer. It also provides syntactic support for it:

from model_values import F
Model.objects.exclude(F.x != 5, a=True)

I am aware that there's already an accepted answer but would like to add my two cents nevertheless:

TLDR: Future and Promise are the two sides of an asynchronous operation: consumer/caller vs. producer/implementor.

As a caller of an asynchronous API method, you will get a Future as a handle to the computation's result. You can e.g. call get() on it to wait for the computation to complete and retrieve the result.

Now think of how this API method is actually implemented: The implementor must return a Future immediately. They are responsible for completing that future as soon as the computation is done (which they will know because it is implementing the dispatch logic ;-)). They will use a Promise/CompletableFuture to do just that: Construct and return the CompletableFuture immediately, and call complete(T result) once the computation is done.

There are situations where you can't use the (quite convincing) with... for... structure. In that case, do the following:

line = self.fo.readline()
if len(line) != 0:
     if 'str' in line:
         break

This will work because the the readline() leaves a trailing newline character, where as EOF is just an empty string.

Angular RC4:

You can import Router from @angular/router

Then inject it:

constructor(private router: Router ) {

}

Then call it's URL parameter:

console.log(this.router.url); //  /routename

Install any UNIX interpreter for windows (Cygwin or Git Bash) and run the cmd:

find /path/to/directory -empty -type d

To find them

find /path/to/directory -empty -type d -delete

To delete them

(not really using the windows cmd prompt but it's easy and took few seconds to run)

A rather separable way of doing this is to use

import tensorflow as tf
from keras import backend as K

num_cores = 4

if GPU:
    num_GPU = 1
    num_CPU = 1
if CPU:
    num_CPU = 1
    num_GPU = 0

config = tf.ConfigProto(intra_op_parallelism_threads=num_cores,
                        inter_op_parallelism_threads=num_cores, 
                        allow_soft_placement=True,
                        device_count = {'CPU' : num_CPU,
                                        'GPU' : num_GPU}
                       )

session = tf.Session(config=config)
K.set_session(session)

Here, with booleans GPU and CPU, we indicate whether we would like to run our code with the GPU or CPU by rigidly defining the number of GPUs and CPUs the Tensorflow session is allowed to access. The variables num_GPU and num_CPU define this value. num_cores then sets the number of CPU cores available for usage via intra_op_parallelism_threads and inter_op_parallelism_threads.

The intra_op_parallelism_threads variable dictates the number of threads a parallel operation in a single node in the computation graph is allowed to use (intra). While the inter_ops_parallelism_threads variable defines the number of threads accessible for parallel operations across the nodes of the computation graph (inter).

allow_soft_placement allows for operations to be run on the CPU if any of the following criterion are met:

1. there is no GPU implementation for the operation

2. there are no GPU devices known or registered

3. there is a need to co-locate with other inputs from the CPU

All of this is executed in the constructor of my class before any other operations, and is completely separable from any model or other code I use.

Note: This requires tensorflow-gpu and cuda/cudnn to be installed because the option is given to use a GPU.

• What do the options in ConfigProto like allow_soft_placement and log_device_placement mean?

• Meaning of inter_op_parallelism_threads and intra_op_parallelism_threads

This is working for me, as described in this thread:

declare let something: string;
something = 'foo';

To convert a string to json and the sting is like json. {"phonetype":"N95","cat":"WP"}

String Data=response.getEntity().getText().toString(); // reading the string value 
JSONObject json = (JSONObject) new JSONParser().parse(Data);
String x=(String) json.get("phonetype");
System.out.println("Check Data"+x);
String y=(String) json.get("cat");
System.out.println("Check Data"+y);

In a word, no. It's not possible using the Selenium WebDriver API. This has been discussed ad nauseam in the issue tracker for the project, and the feature will not be added to the API.

you can pass multiple params in url like

http://localhost:2000/custom?brand=dell&limit=20&price=20000&sort=asc

and in order to get this query fields , you can use map like

    @RequestMapping(method = RequestMethod.GET, value = "/custom")
    public String controllerMethod(@RequestParam Map<String, String> customQuery) {

        System.out.println("customQuery = brand " + customQuery.containsKey("brand"));
        System.out.println("customQuery = limit " + customQuery.containsKey("limit"));
        System.out.println("customQuery = price " + customQuery.containsKey("price"));
        System.out.println("customQuery = other " + customQuery.containsKey("other"));
        System.out.println("customQuery = sort " + customQuery.containsKey("sort"));

        return customQuery.toString();
    }

Extension IDs can be found in:

chrome://extensions (Chrome_Hotdog >> More_tools >> Extensions) Developer mode.

For Linux: $HOME/.config/google-chrome/Default/Preferences (json file) under ["extensions"].

I'm going to take a guess. I think the column name that contains "Number" is something like " Number" or "Number ". Notice that I'm assuming you might have a residual space in the column name somewhere. Do me a favor and run print "<{}>".format(data.columns[1]) and see what you get. Is it something like < Number>? If so, then my guess was correct. You should be able to fix it with this:

data.columns = data.columns.str.strip()

You changed the permissions on the whole directory, which I agree with Splash is a bad idea. If you can remember what the original permissions for the directory are, I would try to set them back to that and then do the following

cd ~/.ssh
chmod 700 id_rsa

inside the .ssh folder. That will set the id_rsa file to rwx (read, write, execute) for the owner (you) only, and zero access for everyone else.

If you can't remember what the original settings are, add a new user and create a set of SSH keys for that user, thus creating a new .ssh folder which will have default permissions. You can use that new .ssh folder as the reference for permissions to reset your .ssh folder and files to.

If that doesn't work, I would try doing an uninstall of msysgit, deleting ALL .ssh folders on the computer (just for safe measure), then reinstalling msysgit with your desired settings and try starting over completely (though I think you told me you tried this already).

Edited: Also just found this link via Google -- Fixing "WARNING: UNPROTECTED PRIVATE KEY FILE!" on Linux While it's targeted at linux, it might help since we're talking liunx permissions and such.

Use .rfind():

>>> s = 'hello'
>>> s.rfind('l')

Also don't use str as variable name or you'll shadow the built-in str().

Reason : Old versions of Tomcat 6 JSP compiler don't seem to be aware of JDK 8 constant pool enhancements - eg. method handles. New code in JDK 8u is using a method handle instead of creating an anonymous class. This will cause the method handle to be listed in the constant pool and the eclipse compiler will choke on this - https://bz.apache.org/bugzilla/show_bug.cgi?id=56613

Heh, there are some pretty exciting uses of ternary syntax in your question; I like the last one the best...

x = (1 < 2) ? true : false;

The use of ternary here is totally unnecessary - you could simply write

x = (1 < 2);

Likewise, the condition element of a ternary statement is always evaluated as a Boolean value, and therefore you can express:

(IsChecked == true) ? removeItem($this) : addItem($this);

Simply as:

(IsChecked) ? removeItem($this) : addItem($this);

In fact, I would also remove the IsChecked temporary as well which leaves you with:

($this.hasClass("IsChecked")) ? removeItem($this) : addItem($this);

As for whether this is acceptable syntax, it sure is! It's a great way to reduce four lines of code into one without impacting readability. The only word of advice I would give you is to avoid nesting multiple ternary statements on the same line (that way lies madness!)

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

A tuple allows you to combine multiple values of possibly different types into a single object without having to create a custom class. This can be useful if you want to write a method that for example returns three related values but you don't want to create a new class.

Usually though you should create a class as this allows you to give useful names to each property. Code that extensively uses tuples will quickly become unreadable because the properties are called Item1, Item2, Item3, etc..

I tried the program below and saw different string each time

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func RandomString(count int){
  rand.Seed(time.Now().UTC().UnixNano()) 
  for(count > 0 ){
    x := Random(65,91)
    fmt.Printf("%c",x)
    count--;
  }
}

func Random(min, max int) (int){
 return min+rand.Intn(max-min) 
}

func main() {
 RandomString(12)
}

And the output on my console is

This works for me every time:

navigator.geolocation.getCurrentPosition(getCoor, errorCoor, {maximumAge:60000, timeout:5000, enableHighAccuracy:true});

Though it isn't very accurate. The funny thing is that on the same device if I run this it puts me off about 100 meters (every time), but if I go to google's maps it finds my location exactly. So although I think the enableHighAccuracy: true helps it to work consistently, it doesn't seem to make it any more accurate...

Take a look at Node#compareDocumentPosition.

function isDescendant(ancestor,descendant){
    return ancestor.compareDocumentPosition(descendant) & 
        Node.DOCUMENT_POSITION_CONTAINS;
}

function isAncestor(descendant,ancestor){
    return descendant.compareDocumentPosition(ancestor) & 
        Node.DOCUMENT_POSITION_CONTAINED_BY;
}

Other relationships include DOCUMENT_POSITION_DISCONNECTED, DOCUMENT_POSITION_PRECEDING, and DOCUMENT_POSITION_FOLLOWING.

Not supported in IE<=8.

Let’s try to keep this least technical.

Let’s say you are sending a html form data to node-js server i.e. you made a request to the server. The server file would receive your request under a request object. Now by logic, if you console log this request object in your server file you should see your form data some where in it, which could be extracted then, but whoa ! you actually don’t !

So, where is our data ? How will we extract it if its not only present in my request.

Simple explanation to this is http sends your form data in bits and pieces which are intended to get assembled as they reach their destination. So how would you extract your data.

But, why take this pain of every-time manually parsing your data for chunks and assembling it. Use something called “body-parser” which would do this for you.

body-parser parses your request and converts it into a format from which you can easily extract relevant information that you may need.

For example, let’s say you have a sign-up form at your frontend. You are filling it, and requesting server to save the details somewhere.

Extracting username and password from your request goes as simple as below if you use body-parser.

var loginDetails = {    
    username : request.body.username,    
    password : request.body.password    
};

So basically, body-parser parsed your incoming request, assembled the chunks containing your form data, then created this body object for you and filled it with your form data.

Once sockaddr cast to sockaddr_in, it becomes this:

struct sockaddr_in {
    u_short     sin_family;
    u_short     sin_port;
    struct      in_addr sin_addr;
    char        sin_zero[8];
};

An old thread, but there is another alternative.

Since 9i you can use pipelined table function.

First, create a type as a table of varchar:

CREATE TYPE t_string_max IS TABLE OF VARCHAR2(32767);

Second, wrap your code in a pipelined function declaration:

CREATE FUNCTION fn_foo (bar VARCHAR2) -- your params
  RETURN t_string_max PIPELINED IS 
  -- your vars
BEGIN
  -- your code
END;
/

Replace all DBMS_OUTPUT.PUT_LINE for PIPE ROW.

Finally, call it like this:

SELECT * FROM TABLE(fn_foo('param'));

Hope it helps.

.container has a max width pixel value, whereas .container-fluid is max-width 100%.

.container-fluid continuously resizes as you change the width of your window/browser by any amount.

.container resizes in chunks at several certain widths, controlled by media queries (technically we can say it’s “fixed width” because pixels values are specified, but if you stop there, people may get the impression that it can’t change size – i.e. not responsive.)

I get that error when i try to run:

python manage.py makemigrations

i tried so many things and realized that i added some references to "settings.py" - "INSTALLED_APPS"

Just be sure what you write there is correct. My mistake was ".model." instead of ".app."

Corrected that mistake and it's working now.

If your table is MyISAM:

SELECT  *
FROM    pages
WHERE   MATCH(title, content) AGAINST ('keyword' IN BOOLEAN MODE)

This will be much faster if you create a FULLTEXT index on your columns:

CREATE FULLTEXT INDEX fx_pages_title_content ON pages (title, content)

, but will work even without the index.

Hope this helps

StringUtils.isBlank also returns true for just whitespace:

I believe you have a very good point and it's one that has been raised in the company where I work. The company is limited in it's ability to apply matlab because of the licensing costs involved. One developer proved that Python was a very suitable replacement but it fell on ignorant ears because to the owners of those ears...

1. No-one in the company knew Python although many of us wanted to use it.
2. MatLab has a name, a company, and task force behind it to solve any problems.
3. There were some (but not a lot) of legacy MatLab projects that would need to be re-written.

If it's worth £10,000 (??) it's gotta be worth it!!

I'm with you here. Python is a very good replacement for MatLab.

I should point out that I've been told the company uses maybe 5% to 10% of MatLabs capabilities and that is the basis for my agreement with the original poster

Using Django's session framework should cover most scenarios, but Django also now provide direct cookie manipulation methods on the request and response objects (so you don't need a helper function).

Setting a cookie:

def view(request):
  response = HttpResponse('blah')
  response.set_cookie('cookie_name', 'cookie_value')

Retrieving a cookie:

def view(request):
  value = request.COOKIES.get('cookie_name')
  if value is None:
    # Cookie is not set

  # OR

  try:
    value = request.COOKIES['cookie_name']
  except KeyError:
    # Cookie is not set

The way I build CMake projects cross platform is the following:

/project-root> mkdir build
/project-root> cd build
/project-root/build> cmake -G "<generator>" -DCMAKE_INSTALL_PREFIX=stage ..
/project-root/build> cmake --build . --target=install --config=Release

• The first two lines create the out-of-source build directory
• The third line generates the build system specifying where to put the installation result (which I always place in ./project-root/build/stage - the path is always considered relative to the current directory if it is not absolute)
• The fourth line builds the project configured in . with the buildsystem configured in the line before. It will execute the install target which also builds all necessary dependent targets if they need to be built and then copies the files into the CMAKE_INSTALL_PREFIX (which in this case is ./project-root/build/stage. For multi-configuration builds, like in Visual Studio, you can also specify the configuration with the optional --config <config> flag.
• The good part when using the cmake --build command is that it works for all generators (i.e. makefiles and Visual Studio) without needing different commands.

Afterwards I use the installed files to create packages or include them in other projects...

We have this problem and to solve

Create a script file called to-utf8.sh

#!/bin/bash
TO="UTF-8"; FILE=$1
FROM=$(file -i $FILE | cut -d'=' -f2)
if [[ $FROM = "binary" ]]; then
 echo "Skipping binary $FILE..."
 exit 0
fi
iconv -f $FROM -t $TO -o $FILE.tmp $FILE; ERROR=$?
if [[ $ERROR -eq 0 ]]; then
  echo "Converting $FILE..."
  mv -f $FILE.tmp $FILE
else
  echo "Error on $FILE"
fi

Set the executable bit

chmod +x to-utf8.sh

Do a conversion

./to-utf8.sh MyFile.txt

If you want to convert all files under a folder, do

find /your/folder/here | xargs -n 1 ./to-utf8.sh

VB 6 provides a Clipboard object that makes all of this extremely simple and convenient, but unfortunately that's not available from VBA.

If it were me, I'd go the API route. There's no reason to be scared of calling native APIs; the language provides you with the ability to do that for a reason.

However, a simpler alternative is to use the DataObject class, which is part of the Forms library. I would only recommend going this route if you are already using functionality from the Forms library in your app. Adding a reference to this library only to use the clipboard seems a bit silly.

For example, to place some text on the clipboard, you could use the following code:

Dim clipboard As MSForms.DataObject
Set clipboard = New MSForms.DataObject
clipboard.SetText "A string value"
clipboard.PutInClipboard

Or, to copy text from the clipboard into a string variable:

Dim clipboard As MSForms.DataObject
Dim strContents As String

Set clipboard = New MSForms.DataObject
clipboard.GetFromClipboard
strContents = clipboard.GetText

Custom String Values for Enum

from http://javahowto.blogspot.com/2006/10/custom-string-values-for-enum.html

The default string value for java enum is its face value, or the element name. However, you can customize the string value by overriding toString() method. For example,

public enum MyType {
  ONE {
      public String toString() {
          return "this is one";
      }
  },

  TWO {
      public String toString() {
          return "this is two";
      }
  }
}

Running the following test code will produce this:

public class EnumTest {
  public static void main(String[] args) {
      System.out.println(MyType.ONE);
      System.out.println(MyType.TWO);
  }
}


this is one
this is two

For a great tutorial the Mozilla Developer Network page on this functionality is all you'll need: https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history

Unfortunately, the HTML5 History API is implemented differently in all the HTML5 browsers (making it inconsistent and buggy) and has no fallback for HTML4 browsers. Fortunately, History.js provides cross-compatibility for the HTML5 browsers (ensuring all the HTML5 browsers work as expected) and optionally provides a hash-fallback for HTML4 browsers (including maintained support for data, titles, pushState and replaceState functionality).

You can read more about History.js here: https://github.com/browserstate/history.js

You can download the JAXB jar files from http://jaxb.java.net/2.2.5/ You don't need to install anything, just invoke the xjc command and with classpath argument pointing to the downloaded JAXB jar files.

Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.

This is expected behavior for an uncaught exception with display_errors off.

Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.

 ini_set("display_errors", 1);

or

 try{
     // code that may throw an exception
 } catch(Exception $e){
     echo $e->getMessage();
 }

If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).

Another option for you would be to use set_exception_handler to set a default error handler for your script.

 function default_exception_handler(Exception $e){
          // show something to the user letting them know we fell down
          echo "<h2>Something Bad Happened</h2>";
          echo "<p>We fill find the person responsible and have them shot</p>";
          // do some logging for the exception and call the kill_programmer function.
 }
 set_exception_handler("default_exception_handler");

in my opinion, if after trying all solution nothing wors then simply delete eclipse folder from your C://use/{pc}/eclipse and then again install the same eclipse . You will get all your data no need to worry.

This happens because of unexpected shutdown of your eclipse

[Updated solution]

can be used with "Normalize" (Canonical decomposition) and "replaceAll", to replace it with the appropriate characters.

import java.text.Normalizer;
import java.text.Normalizer.Form;

public final class NormalizeUtils {

    public static String normalizeASCII(final String string) {
        final String normalize = Normalizer.normalize(string, Form.NFD);

                      .matcher(normalize)
                      .replaceAll("");

With the help of raincoat's code on GitHub, I managed to get a running version accessing the clipboard with plain JavaScript.

function TrelloClipboard() {
    var me = this;

    var utils = {
        nodeName: function (node, name) {
            return !!(node.nodeName.toLowerCase() === name)
        }
    }
    var textareaId = 'simulate-trello-clipboard',
        containerId = textareaId + '-container',
        container, textarea

    var createTextarea = function () {
        container = document.querySelector('#' + containerId)
        if (!container) {
            container = document.createElement('div')
            container.id = containerId
            container.setAttribute('style', [, 'position: fixed;', 'left: 0px;', 'top: 0px;', 'width: 0px;', 'height: 0px;', 'z-index: 100;', 'opacity: 0;'].join(''))
            document.body.appendChild(container)
        }

TrelloClipboard.prototype.setValue = function (value) {
    this.value = value;
}

var clip = new TrelloClipboard();
clip.setValue("test");

Another answer based on extensions (boy do I miss this in Java):

extension NSData {
    func toUtf8() -> String? {
        return String(data: self, encoding: NSUTF8StringEncoding)
    }
}

Then you can use it:

let data : NSData = getDataFromEpicServer()
let string : String? = data.toUtf8() 

Note that the string is optional, the initial NSData may be unconvertible to Utf8.

Open target location of chrome and navigate through cmd type

chrome.exe --disable-web-security --user-data-dir=c:\my\dat

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

With Perl, use Encode::Detect.

To add to other answers. For me it was helpful to delete .mvn directory and then add build.gradle. New versions of IntelliJ will then automatically notice that you use Gradle.

https://docs.python.org/3/library/pickle.html

The pickle protocol formats:

Protocol version 0 is the original “human-readable” protocol and is backwards compatible with earlier versions of Python.

Protocol version 1 is an old binary format which is also compatible with earlier versions of Python.

Protocol version 2 was introduced in Python 2.3. It provides much more efficient pickling of new-style classes. Refer to PEP 307 for information about improvements brought by protocol 2.

Protocol version 3 was added in Python 3.0. It has explicit support for bytes objects and cannot be unpickled by Python 2.x. This is the default protocol, and the recommended protocol when compatibility with other Python 3 versions is required.

Protocol version 4 was added in Python 3.4. It adds support for very large objects, pickling more kinds of objects, and some data format optimizations. Refer to PEP 3154 for information about improvements brought by protocol 4.

Update for swift 2.0 subString

public extension String {
    public subscript (i: Int) -> String {
        return self.substringWithRange(self.startIndex..<self.startIndex.advancedBy(i + 1))
    }

    public subscript (r: Range<Int>) -> String {
        get {
            return self.substringWithRange(self.startIndex.advancedBy(r.startIndex)..<self.startIndex.advancedBy(r.endIndex))
        }
    }

}

On the side bar of the PHP 7 alpha download page, it does say this:

VC9, VC11 & VC14 More recent versions of PHP are built with VC9, VC11 or VC14 (Visual Studio 2008, 2012 or 2015 compiler respectively) and include improvements in performance and stability.

• The VC9 builds require you to have the Visual C++ Redistributable for Visual Studio 2008 SP1 x86 or x64 installed

• The VC11 builds require to have the Visual C++ Redistributable for Visual Studio 2012 x86 or x64 installed

• The VC14 builds require to have the Visual C++ Redistributable for Visual Studio 2015 x86 or x64 installed

^{There's been a problem with some of those links, so the files are also available from Softpedia.}

In the case of the PHP 7 alpha, it's the last option that's required.

I think that the placement of this information is poor, as it's kind of marginalized (i.e.: it's basically literally in the margin!) whereas it's actually critical for the software to run.

I documented my experiences of getting PHP 7 alpha up and running on Windows 8.1 in PHP: getting PHP7 alpha running on Windows 8.1, and it covers some more symptoms that might crop up. They're out of scope for this question but might help other people.

Other symptom of this issue:

• Apache not starting, claiming php7apache2_4.dll is missing despite it definitely being in place, and offering nothing else in any log.
• php-cgi.exe - The FastCGI process exited unexpectedly (as per @ftexperts's comment below)

Attempted solution:

• Using the php7apache2_4.dll file from an earlier PHP 7 dev build. This did not work.

(I include those for googleability.)

See this MSDN article and an example usage here on Stack Overflow.

Let's say that you have the following Linq/POCO class:

public class Color
{
    public int ColorId { get; set; }
    public string Name { get; set; }
}

And let's say that you have the following model:

public class PageModel 
{
   public int MyColorId { get; set; }
}

And, finally, let's say that you have the following list of colors. They could come from a Linq query, from a static list, etc.:

public static IEnumerable<Color> Colors = new List<Color> { 
    new Color {
        ColorId = 1,
        Name = "Red"
    },
    new Color {
        ColorId = 2,
        Name = "Blue"
    }
};

In your view, you can create a drop down list like so:

<%= Html.DropDownListFor(n => n.MyColorId, 
                         new SelectList(Colors, "ColorId", "Name")) %>
