Or you can just create your own MediaTypeFormatter. I use this for text/html. If you add text/plain to it, it'll work for you too:

public class TextMediaTypeFormatter : MediaTypeFormatter
{
    public TextMediaTypeFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
    }

    public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
    {
        return ReadFromStreamAsync(type, readStream, content, formatterLogger, CancellationToken.None);
    }

    public override async Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
    {
        using (var streamReader = new StreamReader(readStream))
        {
            return await streamReader.ReadToEndAsync();
        }
    }

    public override bool CanReadType(Type type)
    {
        return type == typeof(string);
    }

    public override bool CanWriteType(Type type)
    {
        return false;
    }
}

Finally you have to assign this to the HttpMethodContext.ResponseFormatter property.

A cleaner alternative would be to use a Dictionary to handle parameters. They are key-value pairs after all.

private static readonly HttpClient httpclient;

static MyClassName()
{
    // HttpClient is intended to be instantiated once and re-used throughout the life of an application. 
    // Instantiating an HttpClient class for every request will exhaust the number of sockets available under heavy loads. 
    // This will result in SocketException errors.
    // https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=netframework-4.7.1
    httpclient = new HttpClient();    
} 

var url = "http://myserver/method";
var parameters = new Dictionary<string, string> { { "param1", "1" }, { "param2", "2" } };
var encodedContent = new FormUrlEncodedContent (parameters);

var response = await httpclient.PostAsync (url, encodedContent).ConfigureAwait (false);
if (response.StatusCode == HttpStatusCode.OK) {
    // Do something with response. Example get content:
    // var responseContent = await response.Content.ReadAsStringAsync ().ConfigureAwait (false);
}

Also dont forget to Dispose() httpclient, if you dont use the keyword using

As stated in the Remarks section of the HttpClient class in the Microsoft docs, HttpClient should be instantiated once and re-used.

Edit:

You may want to look into response.EnsureSuccessStatusCode(); instead of if (response.StatusCode == HttpStatusCode.OK).

You may want to keep your httpclient and dont Dispose() it. See: Do HttpClient and HttpClientHandler have to be disposed?

Edit:

Do not worry about using .ConfigureAwait(false) in .NET Core. For more details look at https://blog.stephencleary.com/2017/03/aspnetcore-synchronization-context.html

Websites in general can check authorization in many different ways, but the one you're targeting seems to make it reasonably easy for you.

All you need is to POST to the auth/login URL a form-encoded blob with the various fields you see there (forget the labels for, they're decoration for human visitors). handle=whatever&password-clear=pwd and so on, as long as you know the values for the handle (AKA email) and password you should be fine.

Presumably that POST will redirect you to some "you've successfully logged in" page with a Set-Cookie header validating your session (be sure to save that cookie and send it back on further interaction along the session!).

Although accepted answer is right, but IMHO is just a workaround.

To be clear: it's a perfectly normal situation that a persistent connection may become stale. But unfortunately it's very bad when the HTTP client library cannot handle it properly.

Since this faulty behavior in Apache HttpClient was not fixed for many years, I definitely would prefer to switch to a library that can easily recover from a stale connection problem, e.g. OkHttp.

Why?

1. OkHttp pools http connections by default.
2. It gracefully recovers from situations when http connection becomes stale and request cannot be retried due to being not idempotent (e.g. POST). I cannot say it about Apache HttpClient (mentioned NoHttpResponseException).
3. Supports HTTP/2.0 from early drafts and beta versions.

When I switched to OkHttp, my problems with NoHttpResponseException disappeared forever.

You can test-drive this code exactly as is using the public GitHub API (don't go over the request limit):

public class App {

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

        CloseableHttpClient client = HttpClients.custom().build();

        // (1) Use the new Builder API (from v4.3)
        HttpUriRequest request = RequestBuilder.get()
                .setUri("https://api.github.com")
                // (2) Use the included enum
                .setHeader(HttpHeaders.CONTENT_TYPE, "application/json")
                // (3) Or your own
                .setHeader("Your own very special header", "value")
                .build();

        CloseableHttpResponse response = client.execute(request);

        // (4) How to read all headers with Java8
        List<Header> httpHeaders = Arrays.asList(response.getAllHeaders());
        httpHeaders.stream().forEach(System.out::println);

        // close client and response
    }
}

I was frustrated trying to connect my Android App to my RESTful service using https. Also I was a bit annoyed about all the answers that suggested to disable certificate checking altogether. If you do so, whats the point of https?

After googled about the topic for a while, I finally found this solution where external jars are not needed, just Android APIs. Thanks to Andrew Smith, who posted it on July, 2014

 /**
 * Set up a connection to myservice.domain using HTTPS. An entire function
 * is needed to do this because myservice.domain has a self-signed certificate.
 * 
 * The caller of the function would do something like:
 * HttpsURLConnection urlConnection = setUpHttpsConnection("https://littlesvr.ca");
 * InputStream in = urlConnection.getInputStream();
 * And read from that "in" as usual in Java
 * 
 * Based on code from:
 * https://developer.android.com/training/articles/security-ssl.html#SelfSigned
 */
public static HttpsURLConnection setUpHttpsConnection(String urlString)
{
    try
    {
        // Load CAs from an InputStream
        // (could be from a resource or ByteArrayInputStream or ...)
        CertificateFactory cf = CertificateFactory.getInstance("X.509");

        // My CRT file that I put in the assets folder
        // I got this file by following these steps:
        // * Go to https://littlesvr.ca using Firefox
        // * Click the padlock/More/Security/View Certificate/Details/Export
        // * Saved the file as littlesvr.crt (type X.509 Certificate (PEM))
        // The MainActivity.context is declared as:
        // public static Context context;
        // And initialized in MainActivity.onCreate() as:
        // MainActivity.context = getApplicationContext();
        InputStream caInput = new BufferedInputStream(MainActivity.context.getAssets().open("littlesvr.crt"));
        Certificate ca = cf.generateCertificate(caInput);
        System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());

        // Create a KeyStore containing our trusted CAs
        String keyStoreType = KeyStore.getDefaultType();
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);
        keyStore.load(null, null);
        keyStore.setCertificateEntry("ca", ca);

        // Create a TrustManager that trusts the CAs in our KeyStore
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);

        // Create an SSLContext that uses our TrustManager
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, tmf.getTrustManagers(), null);

        // Tell the URLConnection to use a SocketFactory from our SSLContext
        URL url = new URL(urlString);
        HttpsURLConnection urlConnection = (HttpsURLConnection)url.openConnection();
        urlConnection.setSSLSocketFactory(context.getSocketFactory());

        return urlConnection;
    }
    catch (Exception ex)
    {
        Log.e(TAG, "Failed to establish SSL connection to server: " + ex.toString());
        return null;
    }
}

It worked nice for my mockup App.

This exception will come in case your server is based on JDK 7 and your client is on JDK 6 and using SSL certificates. In JDK 7 sslv2hello message handshaking is disabled by default while in JDK 6 sslv2hello message handshaking is enabled. For this reason when your client trying to connect server then a sslv2hello message will be sent towards server and due to sslv2hello message disable you will get this exception. To solve this either you have to move your client to JDK 7 or you have to use 6u91 version of JDK. But to get this version of JDK you have to get the

Adding java.util.list will resolve your problem because List interface which you are trying to use is part of java.util.list package.

Although this question is very old, but I see still there are no exact answer. I will try to answer the question here.

I believe the question in short here is how to set the proxy settings for the Apache commons HttpClient (org.apache.commons.httpclient.HttpClient).

Code snippet below should work :

HttpClient client = new HttpClient();
HostConfiguration hostConfiguration = client.getHostConfiguration();
hostConfiguration.setProxy("localhost", 8080);
client.setHostConfiguration(hostConfiguration);

This is thrown when

... the peer was not able to identify itself (for example; no certificate, the particular cipher suite being used does not support authentication, or no peer authentication was established during SSL handshaking) this exception is thrown.

Probably the cause of this exception (where is the stacktrace) will show you why this exception is thrown. Most likely the default keystore shipped with Java does not contain (and trust) the root certificate of the TTP that is being used.

The answer is to retrieve the root certificate (e.g. from your browsers SSL connection), import it into the cacerts file and trust it using keytool which is shipped by the Java JDK. Otherwise you will have to assign another trust store programmatically.

This depends on what content do you have. You need to initialize your requestMessage.Content property with new HttpContent. For example:

...
// Add request body
if (isPostRequest)
{
    requestMessage.Content = new ByteArrayContent(content);
}
...

where content is your encoded content. You also should include correct Content-type header.

UPDATE:

Oh, it can be even nicer (from this answer):

requestMessage.Content = new StringContent("{\"name\":\"John Doe\",\"age\":33}", Encoding.UTF8, "application/json");

Try this

$client = new \GuzzleHttp\Client();
$client->post(
    'http://www.example.com/user/create',
    array(
        'form_params' => array(
            'email' => '[email protected]',
            'name' => 'Test user',
            'password' => 'testpassword'
        )
    )
);

FWIW the removal of Apache library was foreshadowed a while ago. Our good friend Jesse Wilson gave us a clue back in 2011: http://android-developers.blogspot.com/2011/09/androids-http-clients.html

Google stopped working on ApacheHTTPClient a while ago, so any library that is still relying upon that should be put onto the list of deprecated libraries unless the maintainers update their code.

<rant> I can't tell you how many technical arguments I've had with people who insisted on sticking with Apache HTTP client. There are some major apps that are going to break because management at my not-to-be-named previous employers didn't listen to their top engineers or knew what they were talking about when they ignored the warning ... but, water under the bridge.

I win.

I had the similar issue. The problem was in the passwords: the Keystore and private key used different passwords. (KeyStore explorer was used)

After creating Keystore with the same password as private key had the issue was resolved.

go to the url about:config and paste each line:

network.http.keep-alive.timeout;10
network.http.connection-retry-timeout;10
network.http.pipelining.read-timeout;5
network.http.connection-timeout;10

This worked for me.

The copyIntoClipboard() function works for Flash 9, but it appears to be broken by the release of Flash player 10. Here's a solution that does work with the new flash player:

http://bowser.macminicolo.net/~jhuckaby/zeroclipboard/

It's a complex solution, but it does work.

I recently saw this one-liner:

def foo(name: str, opts: dict=None) -> str:
    opts = {} if not opts else opts
    pass

I can tell you from personal experience this is a bad idea. Native Windows programs cannot accept Cygwin paths. For example with Cygwin you might run a command

grep -r --color foo /opt

with no issue. With Cygwin / represents the root directory. Native Windows programs have no concept of this, and will likely fail if invoked this way. You should not mix Cygwin and Native Windows programs unless you have no other choice.

Uninstall what Git you have and install the Cygwin git package, save yourself the headache.

If you're trying to get the string into a variable, another easy way is something like this:

USAGE=$(cat <<-END
    This is line one.
    This is line two.
    This is line three.
END
)

If you indent your string with tabs (i.e., '\t'), the indentation will be stripped out. If you indent with spaces, the indentation will be left in.

NOTE: It is significant that the last closing parenthesis is on another line. The END text must appear on a line by itself.

Here is an implementation of a delete cookie function with unicode support from Mozilla:

function removeItem(sKey, sPath, sDomain) {
    document.cookie = encodeURIComponent(sKey) + 
                  "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + 
                  (sDomain ? "; domain=" + sDomain : "") + 
                  (sPath ? "; path=" + sPath : "");
}

removeItem("cookieName");

If you use AngularJs, try $cookies.remove (underneath it uses a similar approach):

$cookies.remove('cookieName');

Many way to Json Parse but i have found most effective way to

 @model  List<string[]>

     <script>

         function DataParse() {
             var model = '@Html.Raw(Json.Encode(Model))';
             var data = JSON.parse(model);  

            for (i = 0; i < data.length; i++) {
            ......
             }

     </script>

Another way of configuring backup options is via the Customize interface. Enter:

M-x customize-group

And then at the Customize group: prompt enter backup.

If you scroll to the bottom of the buffer you'll see Backup Directory Alist. Click Show Value and set the first entry of the list as follows:

Regexp matching filename: .*
Backup directory name: /path/to/your/backup/dir

Alternatively, you can turn backups off my setting Make Backup Files to off.

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

3. It is easy to set default to 0 : int array[10] = {0};
4. However, for other values, you have use memset() or loop;

example: int array[10]; memset(array,-1, 10 *sizeof(int));

Starting from a byte array you can use the binary package to do the conversions.

For example if you want to read ints :

buf := bytes.NewBuffer(b) // b is []byte
myfirstint, err := binary.ReadVarint(buf)
anotherint, err := binary.ReadVarint(buf)

The same package allows the reading of unsigned int or floats, with the desired byte orders, using the general Read function.

var list = arr.Select(i => Int32.Parse(i));

Ended up just using the built-in angular attribute ng-checked="model"

here is my initial git commands (possibly, this action takes place in C:/Documents and Settings/your_username/):

mkdir ~/Hello-World
# Creates a directory for your project called "Hello-World" in your user directory
cd ~/Hello-World
# Changes the current working directory to your newly created directory
touch blabla.html
# create a file, named blabla.html
git init
# Sets up the necessary Git files
git add blabla.html
# Stages your blabla.html file, adding it to the list of files to be committed
git commit -m 'first committttt'
# Commits your files, adding the message 
git remote add origin https://github.com/username/Hello-World.git
# Creates a remote named "origin" pointing at your GitHub repository
git push -u origin master
# Sends your commits in the "master" branch to GitHub

If you end up with none of the above working, you might be able to retrieve data using the suggestion from here: http://www.spinics.net/lists/git/msg62499.html

git prune -n
git cat-file -p <blob #>

If you want multiple lines consider this:

<textarea rows="2"></textarea>

Specify rows as needed.

You could regex it:

"string".replace(/^\/?|\/?$/, "")
"/installers/services/".replace(/^\/?|\/?$/, "") // -> installers/services

The regex explained:
- Optional first slash: ^/?, escaped -> ^\/? (the ^ means beginning of string)
- The pipe ( | ) can be read as or
- Than the option slash at the end -> /?$, escaped -> \/?$ ( the $ means end of string)

Combined it would be ^/?|/$ without escaping. Optional first slash OR optional last slash

STOP ALL SERVICES OF XAMPP Edit Apache(httpd.conf) file 1)"Listen 80" if its already 80 and not working then replace it by 81 2) "ServerName localhost:80" if its already 80 and not working then replace it by 81 SAVE EXIT RESTART [WINDOWS USER run as administrator]

Try changing the second parameter in the SaveAs call to Excel.XlFileFormat.xlWorkbookDefault.

When I did that, I generated an xlsx file that I was able to successfully open. (Before making the change, I could produce an xlsx file, but I was unable to open it.)

Also, I'm not sure if it matters or not, but I'm using the Excel 12.0 object library.

The original solution (setting the ForkJoinPool common parallelism property) no longer works. Looking at the links in the original answer, an update which breaks this has been back ported to Java 8. As mentioned in the linked threads, this solution was not guaranteed to work forever. Based on that, the solution is the forkjoinpool.submit with .get solution discussed in the accepted answer. I think the backport fixes the unreliability of this solution also.

ForkJoinPool fjpool = new ForkJoinPool(10);
System.out.println("stream.parallel");
IntStream range = IntStream.range(0, 20);
fjpool.submit(() -> range.parallel()
        .forEach((int theInt) ->
        {
            try { Thread.sleep(100); } catch (Exception ignore) {}
            System.out.println(Thread.currentThread().getName() + " -- " + theInt);
        })).get();
System.out.println("list.parallelStream");
int [] array = IntStream.range(0, 20).toArray();
List<Integer> list = new ArrayList<>();
for (int theInt: array)
{
    list.add(theInt);
}
fjpool.submit(() -> list.parallelStream()
        .forEach((theInt) ->
        {
            try { Thread.sleep(100); } catch (Exception ignore) {}
            System.out.println(Thread.currentThread().getName() + " -- " + theInt);
        })).get();

The documentation for START_STICKY and START_NOT_STICKY is quite straightforward.

START_STICKY:

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

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

Example: Local Service Sample

START_NOT_STICKY:

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

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

Example: ServiceStartArguments.java

Java supports shallow(not deep) copy concept

You can archive it using:

• constructor
• clone()
• putAll()

len=`cat filename | wc -l`
len=$(( $len + 1 ))
l=$(( $len - 99 ))
sed -n "${l},${len}p" filename

first line takes the length (Total lines) of file then +1 in the total lines after that we have to fatch 100 records so, -99 from total length then just put the variables in the sed command to fetch the last 100 lines from file

I hope this will help you.

I'd seriously recommend installing MacVim via MacPorts (sudo port install MacVim).

When installed, MacPorts automatically updates your profile to include /opt/local/bin in your path, and so when mvim is installed as /opt/local/bin/mvim during the install of MacVim you'll find it ready to use straight away.

When you install the MacVim port the MacVim.app bundle is installed in /Applications/MacPorts for you too.

A good thing about going the MacPorts route is that you'll also be able to install git too (sudo port install git-core) and many many other ports. Highly recommended.

Add a -v flag with your git command . e.g. git pull -v

v stands for verify .

@Guffa 's answer is excellent, just point out that maybe is cleaner with an IF statement

select count(IF(Position = 'Manager', 1, NULL)) as ManagerCount
from ...

Yes, it's possible. But first read, "What happens when I change my username?"

To change your username, click your profile picture in the top right corner, then click Settings. On the left side, click Account. Then click Change username.

You can just use strstr() from <string.h>

$ man strstr

For OSX it's even easier. Your machine should come with a version of Apache already installed. All you need to do is locate the php lib for that version (which is likely 5.2.x) and swap it out.

This is the command you'd run from terminal*

cp /usr/libexec/apache2/libphp5.so /Applications/XAMPP/xamppfiles/modules/libphp5.so

I tested this on 10.5 (Leopard), so ymmv. * all the caveats about this might break your system, make a backup, blah blah blah.

Edit: On 10.4 (Tiger), Xampp 1.73, using the libphp5.so-files found at Mamp, this does not work at all.

You can also use sets and get the commonalities in one line: subtract the set containing the differences from one of the sets.

A = [1,2,3,4]
B = [2,4,7,8]
commonalities = set(A) - (set(A) - set(B))

EF 4.1 to EF 6

There is a strongly typed .Include which allows the required depth of eager loading to be specified by providing Select expressions to the appropriate depth:

using System.Data.Entity; // NB!

var company = context.Companies
                     .Include(co => co.Employees.Select(emp => emp.Employee_Car))
                     .Include(co => co.Employees.Select(emp => emp.Employee_Country))
                     .FirstOrDefault(co => co.companyID == companyID);

The Sql generated is by no means intuitive, but seems performant enough. I've put a small example on GitHub here

EF Core

EF Core has a new extension method, .ThenInclude(), although the syntax is slightly different:

var company = context.Companies
                     .Include(co => co.Employees)
                           .ThenInclude(emp => emp.Employee_Car)
                     .Include(co => co.Employees)
                           .ThenInclude(emp => emp.Employee_Country)

With some notes

• As per above (Employees.Employee_Car and Employees.Employee_Country), if you need to include 2 or more child properties of an intermediate child collection, you'll need to repeat the .Include navigation for the collection for each child of the collection.
• As per the docs, I would keep the extra 'indent' in the .ThenInclude to preserve your sanity.

Never ever use a "background color" for your listview rows...

this will block every selector action (was my problem!)

good luck!

In Java, the default initialization is applicable for only instance variable of class member.

It isn't applicable for local variables.

You can try with Angular-Tree-DnD sample with Angular-Ui-Tree, but i edited, compatibility with table, grid, list.

• Extended function directive for list (next, prev, getChildren,...)
• Filter data.
• OrderBy (ver)

String someString = "" + c;
char c = someString.charAt(0);

I am using Asp.Net WebForm and just I wanna to download a file from server side. There is a lot article but I cannot find just basic answer. Now, I tried a basic way and got it.

That's my problem.

I have to create a lot of input button dynamically on runtime. And I want to add each button to download button with giving an unique fileNumber.

I create each button like this:

fragment += "<div><input type=\"button\" value=\"Create Excel\" onclick=\"CreateExcelFile(" + fileNumber + ");\" /></div>";

Each button call this ajax method.

$.ajax({_x000D_
    type: 'POST',_x000D_
    url: 'index.aspx/CreateExcelFile',_x000D_
    data: jsonData,_x000D_
    contentType: 'application/json; charset=utf-8',_x000D_
    dataType: 'json',_x000D_
    success: function (returnValue) {_x000D_
      window.location = '/Reports/Downloads/' + returnValue.d;_x000D_
    }_x000D_
});

Then I wrote a basic simple method.

[WebMethod]
public static string CreateExcelFile2(string fileNumber)
{
    string filePath = string.Format(@"Form_{0}.xlsx", fileNumber);
    return filePath;
}

I am generating this Form_1, Form_2, Form_3.... And I am going to delete this old files with another program. But if there is a way to just sending byte array to download file like using Response. I wanna to use it.

I hope this will be usefull for anyone.

This is an old problem with some good information. But what I just found is that using a FQDN turns off the Compat mode in IE 9 - 11. Example. I have the compat problem with
http://lrmstst01:8080/JavaWeb/login.do
but the problems go away with
http://lrmstst01.mydomain.int:8080/JavaWeb/login.do
NB: The .int is part of our internal domain

I've used this solution to get what you need.

Let'say that in my .aspx code there's a select list runat="server":

<select id="testSelect"  runat="server" ClientIDMode="Static" required>
    <option value="1">One</option>
    <option value="2">Two</option>
</select>

In my C# code I used the code below to retrieve the text and also value of the options:

testSelect.SelectedIndex == 0 ? "uninformed" : 
    testSelect.Items[testSelect.SelectedIndex].Text);

In this case I check if the user selected any of the options. If there's nothing selected I show the text as "uninformed".

If your find doesn't have a -printf option you can also use basename:

find ./dir1 -type f -exec basename {} \;

I solved a similar problem: MainActivity starts BrowserActivity, and I need to close the app, when user press Back in BrowserActivity - not to return in MainActivity. So, in MainActivity:

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "sm500_Rmt.MainActivity";
    private boolean m_IsBrowserStarted = false;

and then, in OnResume:

    @Override
protected void onResume() {
    super.onResume();
    if(m_IsBrowserStarted) {
        Log.w(TAG, "onResume, but it's return from browser, just exit!");
        finish();
        return;
    }
    Log.w(TAG, "onResume");

... then continue OnResume. And, when start BrowserActivity:

    Intent intent = new Intent(this, BrowserActivity.class);
    intent.putExtra(getString(R.string.IPAddr), ip);
    startActivity(intent);
    m_IsBrowserStarted = true;

And it looks like it works good! :-)

TL;DR: The biggest difference in everyday use isn't nested dependencies... it's the difference between modules and globals.

I think the previous posters have covered well some of the basic distinctions. (npm's use of nested dependencies is indeed very helpful in managing large, complex applications, though I don't think it's the most important distinction.)

I'm surprised, however, that nobody has explicitly explained one of the most fundamental distinctions between Bower and npm. If you read the answers above, you'll see the word 'modules' used often in the context of npm. But it's mentioned casually, as if it might even just be a syntax difference.

But this distinction of modules vs. globals (or modules vs. 'scripts') is possibly the most important difference between Bower and npm. The npm approach of putting everything in modules requires you to change the way you write Javascript for the browser, almost certainly for the better.

The Bower Approach: Global Resources, Like <script> Tags

At root, Bower is about loading plain-old script files. Whatever those script files contain, Bower will load them. Which basically means that Bower is just like including all your scripts in plain-old <script>'s in the <head> of your HTML.

So, same basic approach you're used to, but you get some nice automation conveniences:

• You used to need to include JS dependencies in your project repo (while developing), or get them via CDN. Now, you can skip that extra download weight in the repo, and somebody can do a quick bower install and instantly have what they need, locally.
• If a Bower dependency then specifies its own dependencies in its bower.json, those'll be downloaded for you as well.

But beyond that, Bower doesn't change how we write javascript. Nothing about what goes inside the files loaded by Bower needs to change at all. In particular, this means that the resources provided in scripts loaded by Bower will (usually, but not always) still be defined as global variables, available from anywhere in the browser execution context.

The npm Approach: Common JS Modules, Explicit Dependency Injection

All code in Node land (and thus all code loaded via npm) is structured as modules (specifically, as an implementation of the CommonJS module format, or now, as an ES6 module). So, if you use NPM to handle browser-side dependencies (via Browserify or something else that does the same job), you'll structure your code the same way Node does.

Smarter people than I have tackled the question of 'Why modules?', but here's a capsule summary:

• Anything inside a module is effectively namespaced, meaning it's not a global variable any more, and you can't accidentally reference it without intending to.
• Anything inside a module must be intentionally injected into a particular context (usually another module) in order to make use of it
• This means you can have multiple versions of the same external dependency (lodash, let's say) in various parts of your application, and they won't collide/conflict. (This happens surprisingly often, because your own code wants to use one version of a dependency, but one of your external dependencies specifies another that conflicts. Or you've got two external dependencies that each want a different version.)
• Because all dependencies are manually injected into a particular module, it's very easy to reason about them. You know for a fact: "The only code I need to consider when working on this is what I have intentionally chosen to inject here".
• Because even the content of injected modules is encapsulated behind the variable you assign it to, and all code executes inside a limited scope, surprises and collisions become very improbable. It's much, much less likely that something from one of your dependencies will accidentally redefine a global variable without you realizing it, or that you will do so. (It can happen, but you usually have to go out of your way to do it, with something like window.variable. The one accident that still tends to occur is assigning this.variable, not realizing that this is actually window in the current context.)
• When you want to test an individual module, you're able to very easily know: exactly what else (dependencies) is affecting the code that runs inside the module? And, because you're explicitly injecting everything, you can easily mock those dependencies.

To me, the use of modules for front-end code boils down to: working in a much narrower context that's easier to reason about and test, and having greater certainty about what's going on.

It only takes about 30 seconds to learn how to use the CommonJS/Node module syntax. Inside a given JS file, which is going to be a module, you first declare any outside dependencies you want to use, like this:

var React = require('react');

Inside the file/module, you do whatever you normally would, and create some object or function that you'll want to expose to outside users, calling it perhaps myModule.

At the end of a file, you export whatever you want to share with the world, like this:

module.exports = myModule;

Then, to use a CommonJS-based workflow in the browser, you'll use tools like Browserify to grab all those individual module files, encapsulate their contents at runtime, and inject them into each other as needed.

AND, since ES6 modules (which you'll likely transpile to ES5 with Babel or similar) are gaining wide acceptance, and work both in the browser or in Node 4.0, we should mention a good overview of those as well.

More about patterns for working with modules in this deck.

EDIT (Feb 2017): Facebook's Yarn is a very important potential replacement/supplement for npm these days: fast, deterministic, offline package-management that builds on what npm gives you. It's worth a look for any JS project, particularly since it's so easy to swap it in/out.

EDIT (May 2019) "Bower has finally been deprecated. End of story." (h/t: @DanDascalescu, below, for pithy summary.)

And, while Yarn is still active, a lot of the momentum for it shifted back to npm once it adopted some of Yarn's key features.

(And if you have no admin access to the server)

ALTER ROLE <your_login_role> SET search_path TO a,b,c;

Two important things to know about:

1. When a schema name is not simple, it needs to be wrapped in double quotes.
2. The order in which you set default schemas a, b, c matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path.

The window.returnValue property does not work directly when you are opening a window using window.open() while it does work when you are using window.showModalDialog()

So in your case you have two options to achieve what you are trying to do.

Option 1 - Using window.showModalDialog()

In your parent page

var answer = window.showModalDialog(<your page and other arguments>)
if (answer == 1)
 { do some thing with answer }

and inside your child page you can make use of the window.returnValue directly like

window.returnValue = 'value that you want to return';

showModalDialog halts the executions of the JavaScript until the dialog box is closed and can get a return value from the opened dialog box when its closing.But the problem with showModalDialog is that it is not supported on many modern browsers. In contrast window.open just opens a window asynchronously (User can access both the parent window and the opened window). And the JavaScript execution will continue immediately. Which bring us to Option 2

Option 2 - Using window.open() In your parent page write a function that deals with opening of your dialog.

function openDialog(url, width, height, callback){
if(window.showModalDialog){
    options = 'dialogHeight: '+ height + '; dialogWidth: '+ width + '; scroll=no'
    var returnValue = window.showModalDialog(url,this,options);
    callback(returnValue)
}
else {
    options ='toolbar=no, directories=no, location=no, status=yes, menubar=no, resizable=yes, scrollbars=no, width=' + width + ', height=' + height; 
        var childWindow = window.open(url,"",options);
        $(childWindow).on('unload',function(){
            if (childWindow.isOpened == null) {
                childWindow.isOpened = 1;
            }
            else {
                if(callback){
                    callback(childWindow.returnValue);
                }
            }
        });
}

}

And whenever you want to use open a dialog. Write a callback that deals with the return value and pass it as a parameter to openDialog function

function callback(returnValue){
if(returnValue){
    do something nice with the returnValue
}}

And when calling the function

openDialog(<your page>, 'width px', 'height px', callbak);

Check out an article on how to replace window.showModalDialog with window.open

Use round, floor or ceil methods to round it to the closest integer, along with intval() which is limited.

http://php.net/manual/en/function.round.php

http://php.net/manual/en/function.ceil.php

http://php.net/manual/en/function.floor.php

I had the same problem but we can use the time zone we want
we use .toLocaleDateString()

eg:

var day=new Date();
const options= {day:'numeric', month:'long', year:"numeric", timeZone:"Asia/Kolkata"};
const today=day.toLocaleDateString("en-IN", options);
console.log(today);

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

There may be confusion between class privates and module privates.

A module private starts with one underscore
Such a element is not copied along when using the from <module_name> import * form of the import command; it is however imported if using the import <moudule_name> syntax (see Ben Wilhelm's answer)
Simply remove one underscore from the a.__num of the question's example and it won't show in modules that import a.py using the from a import * syntax.

A class private starts with two underscores (aka dunder i.e. d-ouble under-score)
Such a variable has its name "mangled" to include the classname etc.
It can still be accessed outside of the class logic, through the mangled name.
Although the name mangling can serve as a mild prevention device against unauthorized access, its main purpose is to prevent possible name collisions with class members of the ancestor classes. See Alex Martelli's funny but accurate reference to consenting adults as he describes the convention used in regards to these variables.

>>> class Foo(object):
...    __bar = 99
...    def PrintBar(self):
...        print(self.__bar)
...
>>> myFoo = Foo()
>>> myFoo.__bar  #direct attempt no go
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Foo' object has no attribute '__bar'
>>> myFoo.PrintBar()  # the class itself of course can access it
99
>>> dir(Foo)    # yet can see it
['PrintBar', '_Foo__bar', '__class__', '__delattr__', '__dict__', '__doc__', '__
format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__
', '__subclasshook__', '__weakref__']
>>> myFoo._Foo__bar  #and get to it by its mangled name !  (but I shouldn't!!!)

Setting the spring.jackson.default-property-inclusion=non_null option is the simplest solution and it works well.

However, be careful if you implement WebMvcConfigurer somewhere in your code, then the property solution will not work and you will have to setup NON_NULL serialization in the code as the following:

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
    // some of your config here...

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter(objectMapper);
        converters.add(jsonConverter);
    }
}

showInLegend is a series-specific option that can hide the series from the legend. If the requirement is to hide the legends completely then it is better to use enabled: false property as shown below:

legend: { enabled: false }

I know this is an old post but try using an extension method:

    public static IEnumerable<DateTime> Range(this DateTime startDate, DateTime endDate)
    {
        return Enumerable.Range(0, (endDate - startDate).Days + 1).Select(d => startDate.AddDays(d));
    }

and use it like this

    var dates = new DateTime(2000, 1, 1).Range(new DateTime(2000, 1, 31));

Feel free to choose your own dates, you don't have to restrict yourself to January 2000.

Just in case someone only wishes to check if port 22 is open on a remote machine, this simple netcat command is useful. I used it because nmap and telnet were not available for me. Moreover, my ssh configuration uses keyboard password auth.

It is a variant of the solution proposed by GUESSWHOz.

nc -q 0 -w 1 "${remote_ip}" 22 < /dev/null &> /dev/null && echo "Port is reachable" || echo "Port is unreachable"

Finally, I was able to get rid of it using DevToolsSecurity -enable on Terminal. Thanks to @joar_at_work!

FYI: I'm on Xcode 4.3, and pressed the disable button when it launched for the first time, don't ask why, just assume my dog made me do it :)

Its been a while but I have done this in the past using XML as a interim.

I can't take any credit for this, but I'm afraid I no longer know where I got this idea from:

-- declare the variables needed
DECLARE @xml as xml,@str as varchar(100),@delimiter as varchar(10)

-- The string you want to split
SET @str='A,B,C,D,E,Bert,Ernie,1,2,3,4,5'

-- What you want to split on. Can be a single character or a string
SET @delimiter =','

-- Convert it to an XML document
SET @xml = cast(('<X>'+replace(@str,@delimiter ,'</X><X>')+'</X>') as xml)

-- Select back from the XML
SELECT N.value('.', 'varchar(10)') as value FROM @xml.nodes('X') as T(N)

Based on answers from Hogan and Zero Trick Pony. I think this should be both fast and flexible enough to handle well most use cases:

var hash = '####################################################################'

function build_string(length) {  
    if (length == 0) {  
        return ''  
    } else if (hash.length <= length) {  
        return hash.substring(0, length)  
    } else {  
        var result = hash  
        const half_length = length / 2  
        while (result.length <= half_length) {  
            result += result  
        }  
        return result + result.substring(0, length - result.length)  
    }  
}  

If you are working with heavy queries, you better move the request for the latest row in the where clause. It is a lot faster and looks cleaner.

SELECT c.*,
FROM client AS c
LEFT JOIN client_calling_history AS cch ON cch.client_id = c.client_id

      WHERE client_id = c.client_id AND cal_event_id = c.cal_event_id
   )

My own experience has been that it's best to stick to one of two kinds of assembly references:

• A 'local' assembly in the current build directory
• An assembly in the GAC

I've found (much like you've described) other methods to either be too easily broken or have annoying maintenance requirements.

Any assembly I don't want to GAC, has to live in the execution directory. Any assembly that isn't or can't be in the execution directory I GAC (managed by automatic build events).

This hasn't given me any problems so far. While I'm sure there's a situation where it won't work, the usual answer to any problem has been "oh, just GAC it!". 8 D

Hope that helps!

You need to use overflow option like below:

.nav{
    max-height: 300px;
    overflow-y: scroll; 
}

Change the height according to amount of items you need to show

I do this like that:

if (listView1.SelectedItems.Count > 0)
{
     var item = listView1.SelectedItems[0];
     //rest of your logic
}

If you don't want to set max-width to td (like in this answer), you can set max-width to div:

function so_hack(){}

function so_hack(){} http://jsfiddle.net/fd3Zx/754/ function so_hack(){}

function so_hack(){}

Note: 100% doesn't work, but 99% does the trick in FF. Other modern browsers doesn't need silly div hacks.

td {
  border: 1px solid black;
    padding-left:5px;
    padding-right:5px;
}
td>div{
    max-width: 99%;
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;

}

For Angular 6+ things have changed a little.

Define where ng build generates app files

Cli setup is now done in angular.json (replaced .angular-cli.json) in your workspace root directory. The output path in default angular.json should look like this (irrelevant lines removed):

{
  "projects": {
    "my-app-name": {
    "architect": {
      "options": {
         "outputPath": "dist/my-app-name",

Obviously, this will generate your app in WORKSPACE/dist/my-app-name. Modify outputPath if you prefer another directory.

You can overwrite the output path using command line arguments (e.g. for CI jobs):

ng build -op dist/example
ng build --output-path=dist/example

S.a. https://github.com/angular/angular-cli/wiki/build

Hosting angular app in subdirectory

Setting the output path, will tell angular where to place the "compiled" files but however you change the output path, when running the app, angular will still assume that the app is hosted in the webserver's document root.

To make it work in a sub directory, you'll have to set the base href.

In angular.json:

{
  "projects": {
    "my-app-name": {
    "architect": {
      "options": {
         "baseHref": "/my-folder/",

Cli:

ng build --base-href=/my-folder/

If you don't know where the app will be hosted on build time, you can change base tag in generated index.html.

Here's an example how we do it in our docker container:

entrypoint.sh

if [ -n "${BASE_PATH}" ]
then
  files=( $(find . -name "index.html") )
  cp -n "${files[0]}" "${files[0]}.org"
  cp "${files[0]}.org" "${files[0]}"
  sed -i "s*<base href=\"/\">*<base href=\"${BASE_PATH}\">*g" "${files[0]}"
fi

Add margin to your div style

margin:0 10px 10px 0;

http://www.w3schools.com/css/css_margin.asp

Perform three steps:

1. Go to "WorkBench Preferences" --> Choose "SQL Editor" Under "Query Results": check "Treat BINARY/VARBINARY as nonbinary character string"

2. Restart MySQL WorkBench.

3. Now select SELECT SUBSTRING(BLOB<COLUMN_NAME>,1,2500) FROM <Table_name>;

In standard C lua, no. You will have to settle for seconds, unless you are willing to modify the lua interpreter yourself to have os.time use the resolution you want. That may be unacceptable, however, if you are writing code for other people to run on their own and not something like a web application where you have full control of the environment.

Edit: another option is to write your own small DLL in C that extends lua with a new function that would give you the values you want, and require that dll be distributed with your code to whomever is going to be using it.

Partial solution: for a single string column tmp = df['A1'].fillna(''); isEmpty = tmp=='' gives boolean Series of True where there are empty strings or NaN values.

Try this, should work.

val list = List(1,2,4,2,4,7,3,2,4)
list.count(_==2) 

It will return 3

A SELECT INTO statement creates the table for you. There is no need for the CREATE TABLE statement before hand.

What is happening is that you create #ivmy_cash_temp1 in your CREATE statement, then the DB tries to create it for you when you do a SELECT INTO. This causes an error as it is trying to create a table that you have already created.

Either eliminate the CREATE TABLE statement or alter your query that fills it to use INSERT INTO SELECT format.

If you need a unique ID added to your new row then it's best to use SELECT INTO... since IDENTITY() only works with this syntax.

Try adding the RunAs option to your Start-Process

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

I tried using the dtypes=[datetime, ...] option, but

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

I encountered the following error:

TypeError: data type not understood

The only change I had to make is to replace datetime with datetime.datetime

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime.datetime, datetime.datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

I am not the OP of this answer but it helped me so:

I wanted to change the color of the next/previous buttons of the bootstrap carousel on my homepage.

Solution: Copy the selector names from bootstrap.css and move them to your own style.css (with your own prefrences..) :

.carousel-control-prev-icon,
.carousel-control-next-icon {
  height: 100px;
  width: 100px;
  outline: black;
  background-size: 100%, 100%;
  border-radius: 50%;
  border: 1px solid black;
  background-image: none;
}

.carousel-control-next-icon:after
{
  content: '>';
  font-size: 55px;
  color: red;
}

.carousel-control-prev-icon:after {
  content: '<';
  font-size: 55px;
  color: red;
}

if you have two application like (your app, phpmyadmin) just disable APC extension Hope that fix that issue it's worked with me

The emulator tries to find a numeric keypad on the mac, but this is not found (MacBook Pro, MacBook Air and "normal/small" keyboard do not have it). You can deselect the option Connect Hardware Keyboard or just ignore the error message, it will have no negative effect on application.

Try layout() which I have used for this in the past by simply creating an empty plot below, properly scaled at around 1/4 or so and placing the legend parts manually in it.

There are some older questions here about legend() which should get you started.

Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp, BULK_INSERT, and OPENROWSET.

Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.

Here is an attempt at this with your data:

import matplotlib.pyplot as plt

# ... define 2D array hist as you did

plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case

SELECT c.id, c.title, p.id AS product_id, p.title
FROM categories AS c
JOIN products AS p ON c.id = p.category_id
GROUP BY c.id

This will return the first data in products (equals limit 1)

I tried several combinations from existing answers, but they were giving me

DefaultAppPool
IIS APPPOOL
IIS APPPOOL\DefaultAppPool

I ended up using

string vUserName = User.Identity.Name;

Which gave me the actual users domain username only.

They are probably using a virtual host (http://www.keanei.com/2011/07/14/creating-virtual-hosts-with-wamp/)

You can go into your Apache configuration file (httpd.conf) or your virtual host configuration file (recommended) and add something like:

<VirtualHost *:80>
    DocumentRoot /www/ap-mispro
    ServerName ap-mispro

    # Other directives here
</VirtualHost>

And when you call up http://ap-mispro/ you would see whatever is in C:/wamp/www/ap-mispro (assuming default directory structure). The ServerName and DocumentRoot do no have to have the same name at all. Other factors needed to make this work:

1. You have to make sure httpd-vhosts.conf is included by httpd.conf for your changes in that file to take effect.
2. When you make changes to either file, you have to restart Apache to see your changes.
3. You have to change your hosts file http://en.wikipedia.org/wiki/Hosts_(file) for your computer to know where to go when you type http://ap-mispro into your browser. This change to your hosts file will only apply to your computer - not that it sounds like you are trying from anyone else's.

There are plenty more things to know about virtual hosts but this should get you started.

//initialize the 2D vector first

vector<vector<int>> matrix;

//initialize the 1D vector you would like to insert into matrix

vector<int> row;

//initializing row with values

row.push_back(val1);

row.push_back(val2);

//now inserting values into matrix

matrix.push_back(row);

//output- [[val1,val2]]

What you first tried should work, but the HTML is not what we would expect. I added an option to handle the initial "no item selected" case:

<select ng-options="region.code as region.name for region in regions" ng-model="region">
   <option style="display:none" value="">select a region</option>
</select>
<br>selected: {{region}}

The above generates this HTML:

<select ng-options="..." ng-model="region" class="...">
   <option style="display:none" value class>select a region</option>
   <option value="0">Alabama</option>
   <option value="1">Alaska</option>
   <option value="2">American Samoa</option>
</select>

Fiddle

Even though Angular uses numeric integers for the value, the model (i.e., $scope.region) will be set to AL, AK, or AS, as desired. (The numeric value is used by Angular to lookup the correct array entry when an option is selected from the list.)

This may be confusing when first learning how Angular implements its "select" directive.

Carry Flag

The rules for turning on the carry flag in binary/integer math are two:

1. The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)

2. The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).

   • 0111 + 0001 = 1000 (carry flag is turned off [zero])
   • 1000 - 0001 = 0111 (carry flag is turned off [zero])

In unsigned arithmetic, watch the carry flag to detect errors.

In signed arithmetic, the carry flag tells you nothing interesting.

Overflow Flag

The rules for turning on the overflow flag in binary/integer math are two:

1. If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)

2. If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)

Otherwise the "overflow" flag is turned off

• 0100 + 0001 = 0101 (overflow flag is turned off)
• 0110 + 1001 = 1111 (overflow flag turned off)
• 1000 + 0001 = 1001 (overflow flag turned off)
• 1100 + 1100 = 1000 (overflow flag is turned off)

Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.

If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.

If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.

For more clarification please refer: http://teaching.idallen.com/dat2343/10f/notes/040_overflow.txt

Here is a working plunkr with a filter and sortBy pipe. https://plnkr.co/edit/vRvnNUULmBpkbLUYk4uw?p=preview

As developer033 mentioned in a comment, you are passing in a single value to the filter pipe, when the filter pipe is expecting an array of values. I would tell the pipe to expect a single value instead of an array

export class FilterPipe implements PipeTransform {
    transform(items: any[], term: string): any {
        // I am unsure what id is here. did you mean title?
        return items.filter(item => item.id.indexOf(term) !== -1);
    }
}

I would agree with DeborahK that impure pipes should be avoided for performance reasons. The plunkr includes console logs where you can see how much the impure pipe is called.

I found some useful information in a forum page, quoted below.
From this, mainly the sentences in bold formatting, my answer is:

• Make a bash (shell) script version of your .bat file (like other
  answers, with \ changed to / in file paths). For example:

  # File "example.command":
  #!/bin/bash
  java -cp  ".;./supportlibraries/Framework_Core.jar; ...etc.
  

• Then rename it to have the Mac OS file extension .command.
  That should make the script run using the Terminal app.

• If the app user is going to use a bash script version of the file on Linux
  or run it from the command line, they need to add executable rights
  (change mode bits) using this command, in the folder that has the file:

  chmod +rx [filename].sh
  #or:# chmod +rx [filename].command
  

The forum page question:

Good day, [...] I wondering if there are some "simple" rules to write an equivalent
of the Windows (DOS) bat file. I would like just to click on a file and let it run.

Info from some answers after the question:

Write a shell script, and give it the extension ".command". For example:

#!/bin/bash 
printf "Hello World\n" 

- Mar 23, 2010, Tony T1.

The DOS .BAT file was an attempt to bring to MS-DOS something like the idea of the UNIX script.
In general, UNIX permits you to make a text file with commands in it and run it by simply flagging
the text file as executable (rather than give it a specific suffix). This is how OS X does it.

However, OS X adds the feature that if you give the file the suffix .command, Finder
will run Terminal.app to execute it (similar to how BAT files work in Windows).

Unlike MS-DOS, however, UNIX (and OS X) permits you to specify what interpreter is used
for the script. An interpreter is a program that reads in text from a file and does something
with it. [...] In UNIX, you can specify which interpreter to use by making the first line in the
text file one that begins with "#!" followed by the path to the interpreter. For example [...]

#!/bin/sh
echo Hello World

- Mar 23, 2010, J D McIninch.

Also, info from an accepted answer for Equivalent of double-clickable .sh and .bat on Mac?:

On mac, there is a specific extension for executing shell
scripts by double clicking them: this is .command.

AppendDataBoundItems="true" needs to be set.

I found one solution with Nexus 5, and TWRP installed. Basically format was the only solution I found and I tried all solutions listed here before: ADB Android Device Unauthorized

Ask Google to make backup of your apps. Save all important files you may have on your phone

Please note that I decline all liability in case of failure as what I did was quite risky but worked in my case:

Enable USB debugging in developer option (not sure if it helped as device was unauthorized but still...)

Make sure your phone is connected to computer and you can access storage

Download google img of your nexus: https://developers.google.com/android/nexus/images unrar your files and places them in a new folder on your computer, name it factory (any name will do).

wipe ALL datas... you will have 0 file in your android accessed from computer.

Then reboot into BOOTLOADER mode... you will have the message "you have no OS installed are you sure you want to reboot ?"

Then execute (double click) the .bat file inside the "factory" folder.

You will see command line detailed installation of the OS. Of course avoid disconnecting cable during this phase...

Phone will take about 5mn to initialize.

A very direct way is to just use read.table on your character vector:

> read.table(text = text, sep = ".", colClasses = "character")
   V1 V2  V3  V4
1   F US CLE V13
2   F US CA6 U13
3   F US CA6 U13
4   F US CA6 U13
5   F US CA6 U13
6   F US CA6 U13
7   F US CA6 U13
8   F US CA6 U13
9   F US  DL U13
10  F US  DL U13
11  F US  DL U13
12  F US  DL Z13
13  F US  DL Z13

colClasses needs to be specified, otherwise F gets converted to FALSE (which is something I need to fix in "splitstackshape", otherwise I would have recommended that :) )

Update (> a year later)...

Alternatively, you can use my cSplit function, like this:

cSplit(as.data.table(text), "text", ".")
#     text_1 text_2 text_3 text_4
#  1:      F     US    CLE    V13
#  2:      F     US    CA6    U13
#  3:      F     US    CA6    U13
#  4:      F     US    CA6    U13
#  5:      F     US    CA6    U13
#  6:      F     US    CA6    U13
#  7:      F     US    CA6    U13
#  8:      F     US    CA6    U13
#  9:      F     US     DL    U13
# 10:      F     US     DL    U13
# 11:      F     US     DL    U13
# 12:      F     US     DL    Z13
# 13:      F     US     DL    Z13

Or, separate from "tidyr", like this:

library(dplyr)
library(tidyr)

as.data.frame(text) %>% separate(text, into = paste("V", 1:4, sep = "_"))
#    V_1 V_2 V_3 V_4
# 1    F  US CLE V13
# 2    F  US CA6 U13
# 3    F  US CA6 U13
# 4    F  US CA6 U13
# 5    F  US CA6 U13
# 6    F  US CA6 U13
# 7    F  US CA6 U13
# 8    F  US CA6 U13
# 9    F  US  DL U13
# 10   F  US  DL U13
# 11   F  US  DL U13
# 12   F  US  DL Z13
# 13   F  US  DL Z13

Dot grammar maybe more swift!

@(intValueDemo).stringValue 

for example

int intValueDemo  = 1;
//or
NSInteger intValueDemo = 1;

//So you can use dot grammar 
NSLog(@"%@",@(intValueDemo).stringValue);

It's a little memory-inefficient but if you're using the data anyway, I use this frequently:

$rows = $q->fetchAll();
$num_rows = count($rows);

You can also use ls with grep or egrep and put it in your profile as an alias:

ls -l | egrep -v '^d'
ls -l | grep -v '^d'

You just need to add a From: header. By default there is none.

echo "Test" | mail -a "From: Someone <[email protected]>" [email protected]

You can add any custom headers using -a:

echo "Test" | mail -a "From: Someone <[email protected]>" \
                   -a "Subject: This is a test" \

Personally I find it appalling that typescript does not allow an endpoint definition to specify the type of the object being received. As it appears that this is indeed the case, I would do what I have done with other languages, and that is that I would separate the JSON object from the class definition, and have the class definition use the JSON object as its only data member.

I despise boilerplate code, so for me it is usually a matter of getting to the desired result with the least amount of code while preserving type.

Consider the following JSON object structure definitions - these would be what you would receive at an endpoint, they are structure definitions only, no methods.

interface IAddress {
    street: string;
    city: string;
    state: string;
    zip: string;
}

interface IPerson {
    name: string;
    address: IAddress;
}

If we think of the above in object oriented terms, the above interfaces are not classes because they only define a data structure. A class in OO terms defines data and the code that operates on it.

So we now define a class that specifies data and the code that operates on it...

class Person {
    person: IPerson;

    constructor(person: IPerson) {
        this.person = person;
    }

    // accessors
    getName(): string {
        return person.name;
    }

    getAddress(): IAddress {
        return person.address;
    }

    // You could write a generic getter for any value in person, 
    // no matter how deep, by accepting a variable number of string params

    // methods
    distanceFrom(address: IAddress): float {
        // Calculate distance from the passed address to this persons IAddress
        return 0.0;
    }
}

And now we can simply pass in any object conforming to the IPerson structure and be on our way...

   Person person = new Person({
            name: "persons name",
            address: {
                street: "A street address",
                city: "a city",
                state: "a state",
                zip: "A zipcode"
            }
        });

In the same fashion we can now process the object received at your endpoint with something along the lines of...

Person person = new Person(req.body);    // As in an object received via a POST call

person.distanceFrom({ street: "Some street address", etc.});

This is much more performant and uses half the memory of copying the data, while significantly reducing the amount of boilerplate code you must write for each entity type. It simply relies on the type safety provided by TypeScript.

Try using COUNT function like this

=IF(COUNT(SEARCH({"Romney","Obama","Gingrich"},C1)),1,"")

Note that you don't need the wildcards (as teylyn says) and unless there's a specific reason "1" doesn't need quotes (in fact that makes it a text value)

Use position:fixed on the video, set it to 100% width/height, and put a negative z-index on it so it appears behind everything.

If you look at VideoJS, the controls are just html elements sitting on top of the video, using z-index to make sure they're above.

HTML

<video id="video_background" src="video.mp4" autoplay>

(Add webm and ogg sources to support more browsers)

CSS

#video_background {
  position: fixed;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  z-index: -1000;
}

It'll work in most HTML5 browsers, but probably not iPhone/iPad, where the video needs to be activated, and doesn't like elements over it.

If you have a newer version of the Anaconda Navigator, open the Anaconda Prompt program that came in the install. Type all the usual conda update/conda install commands there.

I think the answers above explain this, but I could have used a very simple instruction like this. Perhaps it will help others.

Actually... you can't use a simple regex here, at least not one. You probably need to worry about comments! Someone may write:

<!-- <content> blah </content> -->

You can take two approaches here:

1. Strip all comments out first. Then use the regex approach.
2. Do not use regular expressions and use a context sensitive parsing approach that can keep track of whether or not you are nested in a comment.

Be careful.

I am also not so sure you can match all new lines at once. @Quartz suggested this one:

<content>([^\n]*\n+)+</content>

This will match any content tags that have a newline character RIGHT BEFORE the closing tag... but I'm not sure what you mean by matching all newlines. Do you want to be able to access all the matched newline characters? If so, your best bet is to grab all content tags, and then search for all the newline chars that are nested in between. Something more like this:

<content>.*</content>

BUT THERE IS ONE CAVEAT: regexes are greedy, so this regex will match the first opening tag to the last closing one. Instead, you HAVE to suppress the regex so it is not greedy. In languages like python, you can do this with the "?" regex symbol.

I hope with this you can see some of the pitfalls and figure out how you want to proceed. You are probably better off using an XML parsing library, then iterating over all the content tags.

I know I may not be offering the best solution, but at least I hope you will see the difficulty in this and why other answers may not be right...

UPDATE 1:

Let me summarize a bit more and add some more detail to my response. I am going to use python's regex syntax because it is what I am more used to (forgive me ahead of time... you may need to escape some characters... comment on my post and I will correct it):

To strip out comments, use this regex: Notice the "?" suppresses the .* to make it non-greedy.

Similarly, to search for content tags, use: .*?

Also, You may be able to try this out, and access each newline character with the match objects groups():

<content>(.*?(\n))+.*?</content>

I know my escaping is off, but it captures the idea. This last example probably won't work, but I think it's your best bet at expressing what you want. My suggestion remains: either grab all the content tags and do it yourself, or use a parsing library.

UPDATE 2:

So here is python code that ought to work. I am still unsure what you mean by "find" all newlines. Do you want the entire lines? Or just to count how many newlines. To get the actual lines, try:

#!/usr/bin/python

import re

def FindContentNewlines(xml_text):
    # May want to compile these regexes elsewhere, but I do it here for brevity
    comments = re.compile(r"<!--.*?-->", re.DOTALL)
    content = re.compile(r"<content>(.*?)</content>", re.DOTALL)
    newlines = re.compile(r"^(.*?)$", re.MULTILINE|re.DOTALL)

    # strip comments: this actually may not be reliable for "nested comments"
    # How does xml handle <!--  <!-- --> -->. I am not sure. But that COULD
    # be trouble.
    xml_text = re.sub(comments, "", xml_text)

    result = []
    all_contents = re.findall(content, xml_text)
    for c in all_contents:
        result.extend(re.findall(newlines, c))

    return result

if __name__ == "__main__":
    example = """

<!-- This stuff
ought to be omitted
<content>
  omitted
</content>
-->

This stuff is good
<content>
<p>
  haha!
</p>
</content>

This is not found
"""
    print FindContentNewlines(example)

This program prints the result:

 ['', '<p>', '  haha!', '</p>', '']

The first and last empty strings come from the newline chars immediately preceeding the first <p> and the one coming right after the </p>. All in all this (for the most part) does the trick. Experiment with this code and refine it for your needs. Print out stuff in the middle so you can see what the regexes are matching and not matching.

Hope this helps :-).

PS - I didn't have much luck trying out my regex from my first update to capture all the newlines... let me know if you do.

I think what you want is:

abstract class Component {
  public deps: any = {};
  public props: any = {};

  public makePropSetter<T>(prop: string): (val: T) => T {
    return function(val) {
      this.props[prop] = val
      return val
    }
  }
}

class Post extends Component {
  public toggleBody: (val: boolean) => boolean;

  constructor () {
    super()
    this.toggleBody = this.makePropSetter<boolean>('showFullBody')
  }

  showMore (): boolean {
    return this.toggleBody(true)
  }

  showLess (): boolean {
    return this.toggleBody(false)
  }
}

The important change is in setProp (i.e., makePropSetter in the new code). What you're really doing there is to say: this is a function, which provided with a property name, will return a function which allows you to change that property.

The <T> on makePropSetter allows you to lock that function in to a specific type. The <boolean> in the subclass's constructor is actually optional. Since you're assigning to toggleBody, and that already has the type fully specified, the TS compiler will be able to work it out on its own.

Then, in your subclass, you call that function, and the return type is now properly understood to be a function with a specific signature. Naturally, you'll need to have toggleBody respect that same signature.

Refactored the code from balexandre a little so objects gets disposed and the new language features of C# 3.5+ are used (Linq, var, etc). Also renamed the variables to more meaningful names. I also merged some of the functions to be able to do more configuration with less WMI interaction. I removed the WINS code as I don't need to configure WINS anymore. Feel free to add the WINS code if you need it.

For the case anybody likes to use the refactored/modernized code I put it back into the community here.

This is similar to Solution 1 from @JSuar...

Assume your original city data is a named range called dataCity. In a new sheet, enter the following:

    A                 | B
  ----------------------------------------------------------
1 | =UNIQUE(dataCity) | Count
2 |                   | =DCOUNTA(dataCity,"City",{"City";$A2})
3 |                   | [copy down the formula above]
4 |                   | ...
5 |                   | ...

for my specific problem I had to replace

if let count = 1
    {
        // do something ...
    }

With

let count = 1
if(count > 0)
    {
        // do something ...
    }

You have to open and close your class with { ... } like:

public class mod_MyMod extends BaseMod
{
  public String Version()
  {
    return "1.2_02";
  }

  public void AddRecipes(CraftingManager recipes)
  {
     recipes.addRecipe(new ItemStack(Item.diamond), new Object[] {
        "#", Character.valueOf('#'), Block.dirt });
  }
}

Port 465 is for "smtp over SSL".

http://javamail.kenai.com/nonav/javadocs/com/sun/mail/smtp/package-summary.html

[...] For example, use
    props.put("mail.smtp.port", "888");
to set the mail.smtp.port property, which is of type int.

Note that if you're using the "smtps" protocol to access SMTP over SSL, 
all the properties would be named "mail.smtps.*"

Although in the particular example of the OP's question, switch is not appropriate, there is an example where switch is still appropriate/beneficial, but other evaluation expressions are also required. This can be achieved by using the default clause for the expressions:

switch (foo) {
  case 'bar':
    // do something
    break;
  case 'foo':
    // do something
    break;
  ... // other plain comparison cases
  default:
    if (foo.length > 16) {
      // something specific
    } else if (foo.length < 2) {
      // maybe error
    } else {
      // default action for everything else
    }
}

After a long debug into node js code, mongodb connection string, checking CORS etc, For me just switching to a different port number server.listen(port); made it work, into postman, try that too. No changes to proxy settings just the defaults.

Use npm ls (there is even json output)

From the script:

test.js:

function npmls(cb) {
  require('child_process').exec('npm ls --json', function(err, stdout, stderr) {
    if (err) return cb(err)
    cb(null, JSON.parse(stdout));
  });
}
npmls(console.log);

run:

> node test.js
null { name: 'x11', version: '0.0.11' }

Aha!

I had an OnError() event in some code that was setting the image source to a default image path if it wasn't found. Of course, if the default image path wasn't found it would trigger the error handler...

For people who have a similar problem but not the same, I guess the cause of this is most likely to be either an unterminated loop, an event handler that triggers itself or something similar that throws the JavaScript engine into a spin.

For my specific situation I resolved the problem by using window.postMessage() and eliminating any user interaction. Note that this will only work if you can somehow execute js in the parent window. Either by having it include a js from your domain, or if you have direct access to the source.

In the iframe (domain-b) i check for the presence of a cookie and if it is not set will send a postMessage to the parent (domain-a). Eg;

if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1
    && document.cookie.indexOf("safari_cookie_fix") < 0) {
    window.parent.postMessage(JSON.stringify({ event: "safariCookieFix", data: {} }));
}

Then in the parent window (domain-a) listen for the event.

if (typeof window.addEventListener !== "undefined") {
    window.addEventListener("message", messageReceived, false);
}

function messageReceived (e) {
    var data;

    if (e.origin !== "http://www.domain-b.com") {
        return;
    }

    try {
        data = JSON.parse(e.data);
    }
    catch (err) {
        return;
    }

    if (typeof data !== "object" || typeof data.event !== "string" || typeof data.data === "undefined") {
        return;
    }

    if (data.event === "safariCookieFix") {
        window.location.href = e.origin + "/safari/cookiefix"; // Or whatever your url is
        return;
    }
}

Finally on your server (http://www.domain-b.com/safari/cookiefix) you set the cookie and redirect back to where the user came from. Below example is using ASP.NET MVC

public class SafariController : Controller
{
    [HttpGet]
    public ActionResult CookieFix()
    {
        Response.Cookies.Add(new HttpCookie("safari_cookie_fix", "1"));

        return Redirect(Request.UrlReferrer != null ? Request.UrlReferrer.OriginalString : "http://www.domain-a.com/");
    }

}

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

from werkzeug.datastructures import MultiDict

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

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

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

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

The advantage of Java 1.8 forEach method over 1.7 Enhanced for loop is that while writing code you can focus on business logic only.

forEach method takes java.util.function.Consumer object as an argument, so It helps in having our business logic at a separate location that you can reuse it anytime.

Have look at below snippet,

• Here I have created new Class that will override accept class method from Consumer Class, where you can add additional functionility, More than Iteration..!!!!!!

  class MyConsumer implements Consumer<Integer>{
  
      @Override
      public void accept(Integer o) {
          System.out.println("Here you can also add your business logic that will work with Iteration and you can reuse it."+o);
      }
  }
  
  public class ForEachConsumer {
  
      public static void main(String[] args) {
  
          // Creating simple ArrayList.
          ArrayList<Integer> aList = new ArrayList<>();
          for(int i=1;i<=10;i++) aList.add(i);
  
          //Calling forEach with customized Iterator.
          MyConsumer consumer = new MyConsumer();
          aList.forEach(consumer);
  
  
          // Using Lambda Expression for Consumer. (Functional Interface) 
          Consumer<Integer> lambda = (Integer o) ->{
              System.out.println("Using Lambda Expression to iterate and do something else(BI).. "+o);
          };
          aList.forEach(lambda);
  
          // Using Anonymous Inner Class.
          aList.forEach(new Consumer<Integer>(){
              @Override
              public void accept(Integer o) {
                  System.out.println("Calling with Anonymous Inner Class "+o);
              }
          });
      }
  }
  

public static final long SECOND_IN_MILLIS = 1000;

You could cast int but I would recommend using long.

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

This displays files with its permisions

stat -c '%a - %n' directory/*

You can multiply a list by an integer n to repeat the list n times:

buckets = [0] * 100

You can run in terminal

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/linuxbrew/go/install)"

then install https://github.com/robbyrussell/oh-my-zsh.

When those complate run i.e pico editor pico .zshrc and past those lines:

export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"

remember use brew doctor :)

If you want the conversion to always succeed, probably the best way to convert the string would be to consider "1" as true and anything else as false (as Kevin does). If you wanted the conversion to fail if anything other than "1" or "0" is returned, then the following would suffice (you could put it in a helper method):

if (returnValue == "1")
{
    return true;
}
else if (returnValue == "0")
{
    return false;
}
else
{
    throw new FormatException("The string is not a recognized as a valid boolean value.");
}

Android documents suggests to use getApplicationContext();

but it will not work instead of that use your current activity while instantiating AlertDialog.Builder or AlertDialog or Dialog...

Ex:

AlertDialog.Builder builder = new  AlertDialog.Builder(this);

or

AlertDialog.Builder builder = new  AlertDialog.Builder((Your Activity).this);

It might be helpful to rely on the Workbook factory to instantiate the workbook object since the factory method will do the detection of xls or xlsx for you. Reference: http://apache-poi.1045710.n5.nabble.com/How-to-check-for-valid-excel-files-using-POI-without-checking-the-file-extension-td2341055.html

IWorkbook workbook = WorkbookFactory.Create(inputStream);

If you're not sure of the Sheet's name but you are sure of the index (0 based), you can grab the sheet like this:

ISheet sheet = workbook.GetSheetAt(sheetIndex);

You can then iterate through the rows using code supplied by the accepted answer from mj82

The best and most flexible way

My demo on dabblet.com

The main trick in this demo is that in the normal flow of elements going from top to bottom, so the margin-top: auto is set to zero. However, an absolutely positioned element acts the same for distribution of free space, and similarly can be centered vertically at the specified top and bottom (does not work in IE7).

This trick will work with any sizes of div.

div {_x000D_
 width: 100px;_x000D_
 height: 100px;_x000D_
 background-color: red;_x000D_
 _x000D_
 position: absolute;_x000D_
 top:0;_x000D_
 bottom: 0;_x000D_
 left: 0;_x000D_
 right: 0;_x000D_
   _x000D_
 margin: auto;_x000D_
}

I would recommend overriding the onResume() method in activity number 1, and in there include code to refresh your array adapter, this is done by using [yourListViewAdapater].notifyDataSetChanged();

Sorry, I didn't notice the PHP tag - however someone else might be interested in a VB solution:

Module Module1

    Sub Main()
        Dim d As Date = Now
        Dim nextFriday As Date = DateAdd(DateInterval.Weekday, DayOfWeek.Friday - d.DayOfWeek(), Now)
        Console.WriteLine("next friday is " & nextFriday)
        Console.ReadLine()
    End Sub

End Module

It's the API key as listed under 'API Access', the 'Simple API Access' box.

In my case I just needed to remove Homebrew's executable using:

sudo rm -f `which brew`

Then reinstall Homebrew:

Ways to refer to a child in jQuery. I summarized it in the following jQuery:

$(this).find("img"); // any img tag child or grandchild etc...   
$(this).children("img"); //any img tag child that is direct descendant 
$(this).find("img:first") //any img tag first child or first grandchild etc...
$(this).children("img:first") //the first img tag  child that is direct descendant 
$(this).children("img:nth-child(1)") //the img is first direct descendant child
$(this).next(); //the img is first direct descendant child

If you want to use AngularJs Directive with dynamic template, you can use those answers,But here is more professional and legal syntax of it.You can use templateUrl not only with single value.You can use it as a function,which returns a value as url.That function has some arguments,which you can use.

TO collect all item of an array and return a json object

collectData: function (arrayElements) {

        var main = [];

        for (var i = 0; i < arrayElements.length; i++) {
            var data = {};
            this.e = arrayElements[i];            
            data.text = arrayElements[i].text;
            data.val = arrayElements[i].value;
            main[i] = data;
        }
        return main;
    },

TO parse the same data we go through like this

dummyParse: function (json) {       
        var o = JSON.parse(json); //conerted the string into JSON object        
        $.each(o, function () {
            inner = this;
            $.each(inner, function (index) {
                alert(this.text)
            });
        });

}

I found this post as I was having the same issue, this was the solution that worked for me. As opposed to replacing the input's value just remove it and absolutely position a span behind it that is the same size, the span can have a :before pseudo class applied to it with the icon font of your choice.

<style type="text/css">

form {position: relative; }
.mystyle:before {content:url(smiley.gif); width: 30px; height: 30px; position: absolute; }
.mystyle {color:red; width: 30px; height: 30px; z-index: 1; position: absolute; }
</style>

<form>
<input class="mystyle" type="text" value=""><span class="mystyle"></span>
</form>

On production servers I rename vendor to vendor-<datetime>, and during deployment will have two vendor dirs.

A HTTP cookie causes my system to choose the new vendor autoload.php, and after testing I do a fully atomic/instant switch between them to disable the old vendor dir for all future requests, then I delete the previous dir a few days later.

This avoids any problem caused by filesystem caches I'm using in apache/php, and also allows any active PHP code to continue using the previous vendor dir.

Despite other answers recommending against it, I personally run composer install on the server, since this is faster than rsync from my staging area (a VM on my laptop).

I use --no-dev --no-scripts --optimize-autoloader. You should read the docs for each one to check if this is appropriate on your environment.

There is a method in the String API for those "joining list of string" usecases, you don't even need Stream.

List<String> myStringIterable = Arrays.asList("baguette", "bonjour");

String myReducedString = String.join(",", myStringIterable);

// And here you obtain "baguette,bonjour" in your myReducedString variable

Try it:

document.querySelector("input").addEventListener("keyup", function () {
   this.value = this.value.replace(/\D/, "")
});

I'm not aware if you can create a migration from the command line to do all this, but you can create a new migration, then edit the migration to perform this taks.

If tablename is the name of your table, fieldname is the name of your field and you want to change from a datetime to date, you can write a migration to do this.

You can create a new migration with:

rails g migration change_data_type_for_fieldname

Then edit the migration to use change_table:

class ChangeDataTypeForFieldname < ActiveRecord::Migration
  def self.up
    change_table :tablename do |t|
      t.change :fieldname, :date
    end
  end
  def self.down
    change_table :tablename do |t|
      t.change :fieldname, :datetime
    end
  end
end

Then run the migration:

rake db:migrate

I know this is old but it is still relevant. You can take advantage of reshape2::melt to change the dataframe into a more friendly structure for ggplot2.

Advantages:

• allows you plot any number of lines
• each line with a different color
• adds a legend for each line
• with only one call to ggplot/geom_line

Disadvantage:

• an extra package(reshape2) required
• melting is not so intuitive at first

For example:

jobsAFAM1 <- data.frame(
  data_date = seq.Date(from = as.Date('2017-01-01'),by = 'day', length.out = 100),
  Percent.Change = runif(5,1,100)
)

jobsAFAM2 <- data.frame(
  data_date = seq.Date(from = as.Date('2017-01-01'),by = 'day', length.out = 100),
  Percent.Change = runif(5,1,100)
)

jobsAFAM <- merge(jobsAFAM1, jobsAFAM2, by="data_date")

jobsAFAMMelted <- reshape2::melt(jobsAFAM, id.var='data_date')

ggplot(jobsAFAMMelted, aes(x=data_date, y=value, col=variable)) + geom_line()

I have created XML for following image.

Your XML code for RadioButton will be:

<RadioGroup
        android:id="@+id/daily_weekly_button_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">


        <RadioButton
            android:id="@+id/radio0"
            android:layout_width="@dimen/_80sdp"
            android:gravity="center"
            android:layout_height="wrap_content"
            android:background="@drawable/radio_flat_selector"
            android:button="@android:color/transparent"
            android:checked="true"
            android:paddingLeft="@dimen/_16sdp"
            android:paddingTop="@dimen/_3sdp"
            android:paddingRight="@dimen/_16sdp"
            android:paddingBottom="@dimen/_3sdp"
            android:text="Daily"
            android:textColor="@color/radio_flat_text_selector" />

        <RadioButton
            android:id="@+id/radio1"
            android:gravity="center"
            android:layout_width="@dimen/_80sdp"
            android:layout_height="wrap_content"
            android:background="@drawable/radio_flat_selector"
            android:button="@android:color/transparent"
            android:paddingLeft="@dimen/_16sdp"
            android:paddingTop="@dimen/_3sdp"
            android:paddingRight="@dimen/_16sdp"
            android:paddingBottom="@dimen/_3sdp"
            android:text="Weekly"
            android:textColor="@color/radio_flat_text_selector" />

</RadioGroup>

radio_flat_selector.xml for background selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/radio_flat_selected" android:state_checked="true" />
    <item android:drawable="@drawable/radio_flat_regular" />
</selector>

radio_flat_selected.xml for selected button:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners
        android:radius="1dp"
        />
    <solid android:color="@color/colorAccent" />
    <stroke
        android:width="1dp"
        android:color="@color/colorAccent" />
</shape>

radio_flat_regular.xml for regular selector:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="1dp" />
    <solid android:color="#fff" />
    <stroke
        android:width="1dp"
        android:color="@color/colorAccent" />
</shape>

All the above 3 file code will be in drawable/ folder.

Now we also need Text Color Selector to change color of text accordingly.

radio_flat_text_selector.xml for text color selector

(Use color/ folder for this file.)

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorAccent" android:state_checked="false" />
    <item android:color="@color/colorWhite" android:state_checked="true" />
</selector>

Note: I refereed many answers for this type of solution but didn't found good solution so I make it.

Hope it will be helpful to you.

Thanks.

In .net VB - you could achieve control over columns and rows with the following in your razor file:

@Html.EditorFor(Function(model) model.generalNotes, New With {.htmlAttributes = New With {.class = "someClassIfYouWant", .rows = 5,.cols=6}})

Yes, Java (similar to other mainstream languages) uses lazy evaluation short-circuiting which means it evaluates as little as possible.

This means that the following code is completely safe:

if(p != null && p.getAge() > 10)

Also, a || b never evaluates b if a evaluates to true.

^.+\.(?:(?:[dD][oO][cC][xX]?)|(?:[pP][dD][fF]))$

Will accept .doc, .docx, .pdf files having a filename of at least one character:

^           = beginning of string
.+          = at least one character (any character)
\.          = dot ('.')
(?:pattern) = match the pattern without storing the match)
[dD]        = any character in the set ('d' or 'D')
[xX]?       = any character in the set or none 
              ('x' may be missing so 'doc' or 'docx' are both accepted)
|           = either the previous or the next pattern
$           = end of matched string

Warning! Without enclosing the whole chain of extensions in (?:), an extension like .docpdf would pass.

You can test regular expressions at http://www.regextester.com/

SELECT       
    CASE
        WHEN LastName IS NULL THEN FirstName
        WHEN LastName IS NOT NULL THEN LastName + ', ' + FirstName
    END AS 'FullName'
FROM
    customers
GROUP BY     
    LastName,
    FirstName

This works because the formula you use (the CASE statement) can never give the same answer for two different inputs.

This is not the case if you used something like:

LEFT(FirstName, 1) + ' ' + LastName

In such a case "James Taylor" and "John Taylor" would both result in "J Taylor".

If you wanted your output to have "J Taylor" twice (one for each person):

GROUP BY LastName, FirstName

If, however, you wanted just one row of "J Taylor" you'd want:

GROUP BY LastName, LEFT(FirstName, 1)

Is this value intended? if (scroll <= 500) { ... This means it's happening from 0 to 500, and not 500 and greater. In the original post you said "after the user scrolls down a little"

The very first actions before tunning queries is to defrag/rebuild the indexes and statistics, otherway you're wasting your time.

You must check the execution plan to see if it's stable (is the same when you change the parameters), if not, you might have to create a cover index (in this case for each table) (knowing th system you can create one that is usefull for other queries too).

as an example : create index idx01_datafeed_trans On datafeed_trans ( feedid, feedDate) INCLUDE( acctNo, tradeDate)

if the plan is stable or you can stabilize it you can execute the sentence with sp_executesql('sql sentence') to save and use a fixed execution plan.

if the plan is unstable you have to use an ad-hoc statement or EXEC('sql sentence') to evaluate and create an execution plan each time. (or a stored procedure "with recompile").

Hope it helps.

DISCLAIMER: I'm one of the devs

Since I was look to validate and only allow integers I took one the existing answers and improve it

The idea is to validate from 1 to 12, if the input is lower than 1 it will be set to 1, if the input is higher than 12 it will be set to 12. Decimal simbols are not allowed.

<input id="horaReserva" type="number" min="1" max="12" onkeypress="return isIntegerInput(event)" oninput="maxLengthCheck(this)">

function maxLengthCheck(object) {
    if (object.value.trim() == "") {

    }
    else if (parseInt(object.value) > parseInt(object.max)) {
        object.value = object.max ;
    }
    else if (parseInt(object.value) < parseInt(object.min)) {
        object.value = object.min ;
    }
}

function isIntegerInput (evt) {
    var theEvent = evt || window.event;
    var key = theEvent.keyCode || theEvent.which;
    key = String.fromCharCode (key);
    var regex = /[0-9]/;
    if ( !regex.test(key) ) {
        theEvent.returnValue = false;

        if(theEvent.preventDefault) {
            theEvent.preventDefault();
        }
    }
}

This is a classpath issue when running an executable jar as follows:

java -jar myfile.jar

One way to fix the problem is to set the classpath on the java command line as follows, adding the missing log4j jar:

java -cp myfile.jar:log4j.jar:otherjar.jar com.abc.xyz.MyMainClass

Of course the best solution is to add the classpath into the jar manifest so that the we can use the "-jar" java option:

<jar jarfile="myfile.jar">
    ..
    ..
    <manifest>
       <attribute name="Main-Class" value="com.abc.xyz.MyMainClass"/>
       <attribute name="Class-Path" value="log4j.jar otherjar.jar"/>
    </manifest>
</jar>

The following answer demonstrates how you can use the manifestclasspath to automate the seeting of the classpath manifest entry

The below code works for me, for both accessing and changing a pixel value.

For accessing pixel's channel value :

for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            uchar col = intensity.val[k]; 
        }   
    }
}

For changing a pixel value of a channel :

uchar pixValue;
for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b &intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            // calculate pixValue
            intensity.val[k] = pixValue;
        }
     }
}

You can use the BytesIO class to get a wrapper around strings that behaves like a file. The BytesIO object provides the same interface as a file, but saves the contents just in memory:

import io

with io.BytesIO() as output:
    image.save(output, format="GIF")
    contents = output.getvalue()

You have to explicitly specify the output format with the format parameter, otherwise PIL will raise an error when trying to automatically detect it.

If you loaded the image from a file it has a format parameter that contains the original file format, so in this case you can use format=image.format.

In old Python 2 versions before introduction of the io module you would have used the StringIO module instead.

Instead of putting it on top of the file (or even a header file), just wrap the code in question with #pragma warning (push), #pragma warning (disable) and a matching #pragma warning (pop), as shown here.

Although there are some other options, including #pramga warning (once).

Use map.panTo(); does not do anything if the point is in the current view. Use map.setView() instead.

I had a polyline and I had to center map to a new point in polyline at every second. Check the code : GOOD: https://jsfiddle.net/nstudor/xcmdwfjk/

mymap.setView(point, 11, { animation: true });        

BAD: https://jsfiddle.net/nstudor/Lgahv905/

mymap.panTo(point);
mymap.setZoom(11);

I just found one difference that ended up being important for me. The non-Underscore.js-compatible version of Lodash's _.extend() does not copy over class-level-defined properties or methods.

I've created a Jasmine test in CoffeeScript that demonstrates this:

https://gist.github.com/softcraft-development/1c3964402b099893bd61

Fortunately, lodash.underscore.js preserves Underscore.js's behaviour of copying everything, which for my situation was the desired behaviour.

Try numpy.array_split.

From the documentation:

>>> x = np.arange(8.0)
>>> np.array_split(x, 3)
    [array([ 0.,  1.,  2.]), array([ 3.,  4.,  5.]), array([ 6.,  7.])]

Identical to numpy.split, but won't raise an exception if the groups aren't equal length.

If number of chunks > len(array) you get blank arrays nested inside, to address that - if your split array is saved in a, then you can remove empty arrays by:

[x for x in a if x.size > 0]

Just save that back in a if you wish.

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

git reset does know five "modes": soft, mixed, hard, merge and keep. I will start with the first three, since these are the modes you'll usually encounter. After that you'll find a nice little a bonus, so stay tuned.

soft

When using git reset --soft HEAD~1 you will remove the last commit from the current branch, but the file changes will stay in your working tree. Also the changes will stay on your index, so following with a git commit will create a commit with the exact same changes as the commit you "removed" before.

mixed

This is the default mode and quite similar to soft. When "removing" a commit with git reset HEAD~1 you will still keep the changes in your working tree but not on the index; so if you want to "redo" the commit, you will have to add the changes (git add) before commiting.

hard

When using git reset --hard HEAD~1 you will lose all uncommited changes in addition to the changes introduced in the last commit. The changes won't stay in your working tree so doing a git status command will tell you that you don't have any changes in your repository.

Tread carefully with this one. If you accidentally remove uncommited changes which were never tracked by git (speak: committed or at least added to the index), you have no way of getting them back using git.

Bonus

keep

git reset --keep HEAD~1 is an interesting and useful one. It only resets the files which are different between the current HEAD and the given commit. It aborts the reset if one or more of these files has uncommited changes. It basically acts as a safer version of hard.

You can read more about that in the git reset documentation.

Note
When doing git reset to remove a commit the commit isn't really lost, there just is no reference pointing to it or any of it's children. You can still recover a commit which was "deleted" with git reset by finding it's SHA-1 key, for example with a command such as git reflog.

Here's another way to do it: as we all know 1x byte = 8x bits and also, a "regular" integer (int32) contains 32 bits (4 bytes). We can use the >> operator to shift bits right (>> operator does not change value.)

int intValue = 566;

byte[] bytes = new byte[4];

bytes[0] = (byte)(intValue >> 24);
bytes[1] = (byte)(intValue >> 16);
bytes[2] = (byte)(intValue >> 8);
bytes[3] = (byte)intValue;

Console.WriteLine("{0} breaks down to : {1} {2} {3} {4}",
    intValue, bytes[0], bytes[1], bytes[2], bytes[3]);

ObjectPath is a query language similar to XPath or JSONPath, but much more powerful thanks to embedded arithmetic calculations, comparison mechanisms and built-in functions. See the syntax:

Find in the shop all shoes of red color and price less than 50

$..shoes.*[color is "red" and price < 50]

If you are using Android Studio 3.5+, Changing font is super simple. Select the text widget on Design view and check fontFamily on Attribute Window. The value dropdown contains all the available fonts from which you can select one. If you are looking for Google Fonts, Click More Fonts option.

Attribute Window

Google Fonts

This works:

SELECT STR_TO_DATE(dateColumn, '%c/%e/%Y %r') FROM tabbleName WHERE 1

Instead of

background-repeat-x: no-repeat;
background-repeat-y: no-repeat;

which is not correct, use

background-repeat: no-repeat;

try doing:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    card_view:cardElevation="2dp"
    card_view:cardCornerRadius="5dp">

    <FrameLayout
        android:background="#FF0000"
        android:layout_width="4dp"
        android:layout_height="match_parent"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding="16dp"
        android:orientation="vertical">

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Headline"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Title" />

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Body1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Content here" />

    </LinearLayout>

</android.support.v7.widget.CardView>

this removes the padding from the cardview and adds a FrameLayout with a color. You then need to fix the padding in the LinearLayout then for the other fields

Update

If you want to preserve the card corner radius create card_edge.xml in drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#F00" />
    <size android:width="10dp"/>
    <padding android:bottom="0dp" android:left="0dp" android:right="0dp" android:top="0dp"/>
    <corners android:topLeftRadius="5dp" android:bottomLeftRadius="5dp"
        android:topRightRadius="0.1dp" android:bottomRightRadius="0.1dp"/>
</shape>

and in the frame layout use android:background="@drawable/card_edge"

Sometimes the problem may be if you import that like this:

const Vue = window.vue;

this may overwrite the original Vue reference.

It is not possible because they are executed in different environments (JSP at server side, JavaScript at client side). So they are not executed in the sequence you see in your code.

var val1 = document.getElementById('userName').value; 

<c:set var="user" value=""/>  // how do i set val1 here? 

Here JSTL code is executed at server side and the server sees the JavaScript/Html codes as simple texts. The generated contents from JSTL code (if any) will be rendered in the resulting HTML along with your other JavaScript/HTML codes. Now the browser renders HTML along with executing the Javascript codes. Now remember there is no JSTL code available for the browser.

Now for example,

<script type="text/javascript">
<c:set var="message" value="Hello"/> 
var message = '<c:out value="${message}"/>';
</script>

Now for the browser, this content is rendered,

<script type="text/javascript">
var message = 'Hello';
</script>

Hope this helps.

If you are trying to delete/cut as suggested by @Pacific P. Regmi and if you are getting "Folder in use" which won't let you to delete/cut make sure to close all the android studio instances.

I you're happy with console emacs (emacs -nw), modern vterm implementations (like gnome-terminal) tend to have better font support. Plus if you get used to that, you can then use tmux, and so working with your full environment on remote servers becomes possible, even without X.

I may be just repeating everyone else but I do have a pretty piece of code that extends the DependencyObject class with a method FindChild() that will get you the child by type and name. Just include and use.

public static class UIChildFinder
{
    public static DependencyObject FindChild(this DependencyObject reference, string childName, Type childType)
    {
        DependencyObject foundChild = null;
        if (reference != null)
        {
            int childrenCount = VisualTreeHelper.GetChildrenCount(reference);
            for (int i = 0; i < childrenCount; i++)
            {
                var child = VisualTreeHelper.GetChild(reference, i);
                // If the child is not of the request child type child
                if (child.GetType() != childType)
                {
                    // recursively drill down the tree
                    foundChild = FindChild(child, childName, childType);
                }
                else if (!string.IsNullOrEmpty(childName))
                {
                    var frameworkElement = child as FrameworkElement;
                    // If the child's name is set for search
                    if (frameworkElement != null && frameworkElement.Name == childName)
                    {
                        // if the child's name is of the request name
                        foundChild = child;
                        break;
                    }
                }
                else
                {
                    // child element found.
                    foundChild = child;
                    break;
                }
            }
        }
        return foundChild;
    }
}

Hope you find it useful.

In Oracle:

SELECT 'Hello world' FROM dual

Dual equivalent in SQL Server:

SELECT 'Hello world' 

Could use sprintf to accomplish this:

awk '{str = sprintf("%s %s", $1, $2)} END {print str}' file

I would personally prefer using "\n". This just puts a line break in Linux or Android.

For example,

String str = "I am the first part of the info being emailed.\nI am the second part.\n\nI am the third part.";

Output

I am the first part of the info being emailed.
I am the second part.

I am the third part.

A more generalized way would be to use,

System.getProperty("line.separator")

For example,

String str = "I am the first part of the info being emailed." + System.getProperty("line.separator") + "I am the second part." + System.getProperty("line.separator") + System.getProperty("line.separator") + "I am the third part.";

brings the same output as above. Here, the static getProperty() method of the System class can be used to get the "line.seperator" for the particular OS.

But this is not necessary at all, as the OS here is fixed, that is, Android. So, calling a method every time is a heavy and unnecessary operation.

Moreover, this also increases your code length and makes it look kind of messy. A "\n" is sweet and simple.

Use:

SELECT * 
FROM [Janus999DB].[dbo].[tblCustomerPlay] 
WHERE DatePlayed <  GetDate() 
AND DatePlayed > dateadd(minute, -30, GetDate())

git rev-list --exclude=master --branches --no-walk

will list the tips of every branch that isn't master.

git rev-list master --not $(git rev-list --exclude=master --branches --no-walk)

will list every commit in master's history that's not in any other branch's history.

Sequencing is important for the options that set up the filter pipeline for commit selection, so --branches has to follow any exclusion patterns it's supposed to apply, and --no-walk has to follow the filters supplying commits rev-list isn't supposed to walk.

Time Zone

The accepted answer is correct, except that it ignores the crucial issue of time zone. Is your input string 6:10 PM in Paris or Montréal? Or UTC?

Use a proper time zone name. Usually a continent plus city/region. For example, "Europe/Oslo". Avoid the 3 or 4 letter codes which are neither standardized nor unique.

java.time

The modern approach uses the java.time classes.

Alter your input to conform with the ISO 8601 standard. Replace the SPACE in the middle with a T. And replace the slash characters with hyphens. The java.time classes use these standard formats by default when parsing/generating strings. So no need to specify a formatting pattern.

String input = "2014/10/29 18:10:45".replace( " " , "T" ).replace( "/" , "-" ) ;
LocalDateTime ldt = LocalDateTime.parse( input ) ;

A LocalDateTime, like your input string, lacks any concept of time zone or offset-from-UTC. Without the context of a zone/offset, a LocalDateTime has no real meaning. Is it 6:10 PM in India, Europe, or Canada? Each of those places experience 6:10 PM at different moments, at different points on the timeline. So you must specify which you have in mind if you want to determine a specific point on the timeline.

ZoneId z = ZoneId.of( "Europe/Oslo" ) ;
ZonedDateTime zdt = ldt.atZone( z ) ;  

Now we have a specific moment, in that ZonedDateTime. Convert to UTC by extracting a Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = zdt.toInstant() ;

Now we can get your desired count of milliseconds since the epoch reference of first moment of 1970 in UTC, 1970-01-01T00:00Z.

long millisSinceEpoch = instant.toEpochMilli() ; 

Be aware of possible data loss. The Instant object is capable of carrying microseconds or nanoseconds, finer than milliseconds. That finer fractional part of a second will be ignored when getting a count of milliseconds.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Joda-Time

Update: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. I will leave this section intact for history.

Below is the same kind of code but using the Joda-Time 2.5 library and handling time zone.

The java.util.Date, .Calendar, and .SimpleDateFormat classes are notoriously troublesome, confusing, and flawed. Avoid them. Use either Joda-Time or the java.time package (inspired by Joda-Time) built into Java 8.

ISO 8601

Your string is almost in ISO 8601 format. The slashes need to be hyphens and the SPACE in middle should be replaced with a T. If we tweak that, then the resulting string can be fed directly into constructor without bothering to specify a formatter. Joda-Time uses ISO 8701 formats as it's defaults for parsing and generating strings.

Example Code

String inputRaw = "2014/10/29 18:10:45";
String input = inputRaw.replace( "/", "-" ).replace( " ", "T" );
DateTimeZone zone = DateTimeZone.forID( "Europe/Oslo" ); // Or DateTimeZone.UTC
DateTime dateTime = new DateTime( input, zone );
long millisecondsSinceUnixEpoch = dateTime.getMillis();

Although it's not listed on the API doc page anymore, I found a thread that mentions that you can use self in place of user-id for the users/{user-id} endpoint and it'll return the currently authenticated user's info.

So, users/self is the same as an explicit call to users/{some-user-id} and contains the user's id as part of the payload. Once you're authenticated, just make a call to users/self and the result will include the currently authenticated user's id, like so:

{
    "data": {
        "id": "1574083",
        "username": "snoopdogg",
        "full_name": "Snoop Dogg",
        "profile_picture": "http://distillery.s3.amazonaws.com/profiles/profile_1574083_75sq_1295469061.jpg",
        "bio": "This is my bio",
        "website": "http://snoopdogg.com",
        "counts": {
            "media": 1320,
            "follows": 420,
            "followed_by": 3410
        }
}

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

For right labels use ax.yaxis.set_label_position("right"), i.e.:

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_label_position("right")
plt.plot([2,3,4,5])
ax.set_xlabel("$x$ /mm")
ax.set_ylabel("$y$ /mm")
plt.show()

If it is for binding, then you can reference indexers from XAML

Text="{Binding [FullName]}"

Here it is referencing the class indexer with the key "FullName"

Yes, you can modify or update the values of objects in the list in your case likewise:

users.stream().forEach(u -> u.setProperty("some_value"))

However, the above statement will make updates on the source objects. Which may not be acceptable in most cases.

Luckily, we do have another way like:

List<Users> updatedUsers = users.stream().map(u -> u.setProperty("some_value")).collect(Collectors.toList());

Which returns an updated list back, without hampering the old one.

In Excel for Mac 2016 at least,if you place the labels in any spot on the graph and are looking to move them anywhere else (in this case above the bars), select:

Chart Design->Add Chart Element->Data Labels -> More Data Label Options

then you can grab each individual label and pull it where you would like it.

@Adrian's answer is perfectly suitable, I just wanted to share another way of achieving the same result:

select nvl(a.id, b.id)
from a full outer join b on a.id = b.id
order by b.id;

You would need to do this manually, by adding a a static map in the class that maps Integers to enums, such as

private static final Map<Integer, PcapLinkType> intToTypeMap = new HashMap<Integer, PcapLinkType>();
static {
    for (PcapLinkType type : PcapLinkType.values()) {
        intToTypeMap.put(type.value, type);
    }
}

public static PcapLinkType fromInt(int i) {
    PcapLinkType type = intToTypeMap.get(Integer.valueOf(i));
    if (type == null) 
        return PcapLinkType.DLT_UNKNOWN;
    return type;
}

tldr;

$ od -t x1 -A n -v <empty.zip | tr -dc '[:xdigit:]' && echo 
504b0506000000000000000000000000000000000000
$

Explanation:

Use the od tool to print single hexadecimal bytes (-t x1) --- without address offsets (-A n) and without eliding repeated "groups" (-v) --- from empty.zip, which has been redirected to standard input. Pipe that to tr which deletes (-d) the complement (-c) of the hexadecimal character set ('[:xdigit:]'). You can optionally print a trailing newline (echo) as I've done here to separate the output from the next shell prompt.

In Swift 3.01 using WKWebView:

let localURL = URL.init(fileURLWithPath: Bundle.main.path(forResource: "index", ofType: "html", inDirectory: "CWP")!)
myWebView.load(NSURLRequest.init(url: localURL) as URLRequest)

This adjusts for some of the finer syntax changes in 3.01 and keeps the directory structure in place so you can embed related HTML files.
