Almost all above solutions used the ActiveDirecotry module which might not be available by default in most cases.

I used below method. A bit indirect, but served my purpose.

List all available groups

Get-WmiObject -Class Win32_Group

And then list the groups the user belongs to

[System.Security.Principal.WindowsIdentity]::GetCurrent().Groups

Comparison can then be done via checking through the SIDs. This works for the logged in user. Please correct me if I am wrong. Completely new to PowerShell, but had to get this done for a work commitment.

Junit is included by default with Eclipse (at least the Java EE version I'm sure). You may just need to add the view to your perspective.

Why would you make it VARCHAR? It doesn't vary. It's always 64 characters, which can be determined by running anything into one of the online SHA-256 calculators.

UPDATE:
This answer turned out to be wrong. Please see the comments for the real explanation.

Most of you question has been answered, but as for the final part:

What would be the danger of both copies coming through?

None really. You'd waste bandwidth, might add some milliseconds downloading a second useless copy, but there's not actual harm if they both come through. You should, of course, avoid this using the techniques mentioned above.

git diff -a treats all file as text and it works for me.

Maybe I didn't understand the question correctly, but can you not use keyup if you want to capture both inputs?

$("input").bind("keyup",function(e){
    var value = this.value + String.fromCharCode(e.keyCode);
});

Please follow those steps.

Bundle your js:

if you have index.android.js in project root then run

react-native bundle --dev false --platform android --entry-file index.android.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug

if you have index.js in project root then run

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

Create debug apk:

cd android/
./gradlew assembleDebug

Then You can find your apk here:

cd app/build/outputs/apk/

I have implemented BasicAuthenticationHandler for basic authentication so you can use it with standart attributes Authorize and AllowAnonymous.

public class BasicAuthenticationHandler : AuthenticationHandler<BasicAuthenticationOptions>
{
    protected override Task<AuthenticateResult> HandleAuthenticateAsync()
    {
        var authHeader = (string)this.Request.Headers["Authorization"];

        if (!string.IsNullOrEmpty(authHeader) && authHeader.StartsWith("basic", StringComparison.OrdinalIgnoreCase))
        {
            //Extract credentials
            string encodedUsernamePassword = authHeader.Substring("Basic ".Length).Trim();
            Encoding encoding = Encoding.GetEncoding("iso-8859-1");
            string usernamePassword = encoding.GetString(Convert.FromBase64String(encodedUsernamePassword));

            int seperatorIndex = usernamePassword.IndexOf(':', StringComparison.OrdinalIgnoreCase);

            var username = usernamePassword.Substring(0, seperatorIndex);
            var password = usernamePassword.Substring(seperatorIndex + 1);

            //you also can use this.Context.Authentication here
            if (username == "test" && password == "test")
            {
                var user = new GenericPrincipal(new GenericIdentity("User"), null);
                var ticket = new AuthenticationTicket(user, new AuthenticationProperties(), Options.AuthenticationScheme);
                return Task.FromResult(AuthenticateResult.Success(ticket));
            }
            else
            {
                return Task.FromResult(AuthenticateResult.Fail("No valid user."));
            }
        }

        this.Response.Headers["WWW-Authenticate"]= "Basic realm=\"yourawesomesite.net\"";
        return Task.FromResult(AuthenticateResult.Fail("No credentials."));
    }
}

public class BasicAuthenticationMiddleware : AuthenticationMiddleware<BasicAuthenticationOptions>
{
    public BasicAuthenticationMiddleware(
       RequestDelegate next,
       IOptions<BasicAuthenticationOptions> options,
       ILoggerFactory loggerFactory,
       UrlEncoder encoder)
       : base(next, options, loggerFactory, encoder)
    {
    }

    protected override AuthenticationHandler<BasicAuthenticationOptions> CreateHandler()
    {
        return new BasicAuthenticationHandler();
    }
}

public class BasicAuthenticationOptions : AuthenticationOptions
{
    public BasicAuthenticationOptions()
    {
        AuthenticationScheme = "Basic";
        AutomaticAuthenticate = true;
    }
}

Registration at Startup.cs - app.UseMiddleware<BasicAuthenticationMiddleware>();. With this code, you can restrict any controller with standart attribute Autorize:

[Authorize(ActiveAuthenticationSchemes = "Basic")]
[Route("api/[controller]")]
public class ValuesController : Controller

and use attribute AllowAnonymous if you apply authorize filter on application level.

If you are using Auto mapper and facing the the issue following is the good solution, it work for me

https://www.codeproject.com/Articles/576393/Solutionplusto-aplus-Theplusoperationplusfailed

Since the problem is that we're mapping null navigation properties, and we actually don't need them to be updated on the Entity since they didn't changed on the Contract, we need to ignore them on the mapping definition:

ForMember(dest => dest.RefundType, opt => opt.Ignore())

So my code ended up like this:

Mapper.CreateMap<MyDataContract, MyEntity>
ForMember(dest => dest.NavigationProperty1, opt => opt.Ignore())
ForMember(dest => dest.NavigationProperty2, opt => opt.Ignore())
.IgnoreAllNonExisting();

If you want to use managed code: This will capture any window via the ProcessId.

I used the following to make the window active.

Microsoft.VisualBasic.Interaction.AppActivate(ProcessId);
Threading.Thread.Sleep(20);

I used the print screen to capture a window.

SendKeys.SendWait("%{PRTSC}");
Threading.Thread.Sleep(40);
IDataObject objData = Clipboard.GetDataObject();

With Javascript you can get full size profile images like this

pass your accessToken to the getface() function from your FB.init call

function getface(accessToken){
  FB.api('/me/friends', function (response) {
    for (id in response.data) { 
        var homie=response.data[id].id         
        FB.api(homie+'/albums?access_token='+accessToken, function (aresponse) {
          for (album in aresponse.data) {
            if (aresponse.data[album].name == "Profile Pictures") {                      
              FB.api(aresponse.data[album].id + "/photos", function(aresponse) {
                console.log(aresponse.data[0].images[0].source); 
              });                  
            }
          }   
        });
    }
  });
}

Here's what I use:

NSString * timestamp = [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000];

(times 1000 for milliseconds, otherwise, take that out)

If You're using it all the time, it might be nice to declare a macro

#define TimeStamp [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000]

Then Call it like this:

NSString * timestamp = TimeStamp;

Or as a method:

- (NSString *) timeStamp {
    return [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000];
}

As TimeInterval

- (NSTimeInterval) timeStamp {
    return [[NSDate date] timeIntervalSince1970] * 1000;
}

NOTE:

The 1000 is to convert the timestamp to milliseconds. You can remove this if you prefer your timeInterval in seconds.

Swift

If you'd like a global variable in Swift, you could use this:

var Timestamp: String {
    return "\(NSDate().timeIntervalSince1970 * 1000)"
}

Then, you can call it

println("Timestamp: \(Timestamp)")

Again, the *1000 is for miliseconds, if you'd prefer, you can remove that. If you want to keep it as an NSTimeInterval

var Timestamp: NSTimeInterval {
    return NSDate().timeIntervalSince1970 * 1000
}

Declare these outside of the context of any class and they'll be accessible anywhere.

Getting into a non-password protected Java keystore and changing the password can be done with a help of Java programming language itself.

That article contains the code for that:

Without lambda:

def sec_elem(s):
    return s[1]

sorted(data, key=sec_elem)

In boto 3, the 'Key.set_contents_from_' methods were replaced by

• Object.put()

• Client.put_object()

For example:

import boto3

some_binary_data = b'Here we have some data'
more_binary_data = b'Here we have some more data'

# Method 1: Object.put()
s3 = boto3.resource('s3')
object = s3.Object('my_bucket_name', 'my/key/including/filename.txt')
object.put(Body=some_binary_data)

# Method 2: Client.put_object()
client = boto3.client('s3')
client.put_object(Body=more_binary_data, Bucket='my_bucket_name', Key='my/key/including/anotherfilename.txt')

Alternatively, the binary data can come from reading a file, as described in the official docs comparing boto 2 and boto 3:

Storing Data

Storing data from a file, stream, or string is easy:

# Boto 2.x
from boto.s3.key import Key
key = Key('hello.txt')
key.set_contents_from_file('/tmp/hello.txt')

# Boto 3
s3.Object('mybucket', 'hello.txt').put(Body=open('/tmp/hello.txt', 'rb'))

try:

SELECT CAST( CAST([field] AS VARBINARY) AS varchar) 

For me, the Twitter Bootstrap Solution looks good. It excludes IE < 9 (no round corners in IE 8 and lower), but that's O.K. I think, if you develop prospective Web-Apps.

You can play with that here (on jsFiddle)

You can think of reshaping that the new shape is filled row by row (last dimension varies fastest) from the flattened original list/array.

An easy solution is to shape the list into a (100, 28) array and then transpose it:

x = np.reshape(list_data, (100, 28)).T

Update regarding the updated example:

np.reshape([0, 0, 1, 1, 2, 2, 3, 3], (4, 2)).T
# array([[0, 1, 2, 3],
#        [0, 1, 2, 3]])

np.reshape([0, 0, 1, 1, 2, 2, 3, 3], (2, 4))
# array([[0, 0, 1, 1],
#        [2, 2, 3, 3]])

What you're trying to insert is not a date, I think, but a string. You need to use to_date() function, like this:

insert into table t1 (id, date_field) values (1, to_date('20.06.2013', 'dd.mm.yyyy'));

The best practice to download an image from Server or from Website and store it locally.

WebClient client=new Webclient();

Separate 'em with a space.

You cannot use AppSettings static object for this. Try this

string appPath = System.IO.Path.GetDirectoryName(Reflection.Assembly.GetExecutingAssembly().Location);          
string configFile = System.IO.Path.Combine(appPath, "App.config");
ExeConfigurationFileMap configFileMap = new ExeConfigurationFileMap();         
configFileMap.ExeConfigFilename = configFile;          
System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);

config.AppSettings.Settings["YourThing"].Value = "New Value"; 
config.Save(); 

Using unless is fine for statements with single include? clauses but, for example, when you need to check the inclusion of something in one Array but not in another, the use of include? with exclude? is much friendlier.

if @players.include? && @spectators.exclude? do
  ....
end

But as dizzy42 says above, the use of exclude? requires ActiveSupport

len = max(key for (item, key) in list)
newlist = [[] for i in range(len+1)]
for item,key in list:
  newlist[key].append(item)

You can do it in a single list comprehension, perhaps more elegant but O(n**2):

[[item for (item,key) in list if key==i] for i in range(max(key for (item,key) in list)+1)]

If the readability of the file name isn't important, then the GUID, as suggested by many will do. However, I find that looking into a directory with 1000 GUID file names is very daunting to sort through. So I usually use a combination of a static string which gives the file name some context information, a timestamp, and GUID.

For example:

public string GenerateFileName(string context)
{
    return context + "_" + DateTime.Now.ToString("yyyyMMddHHmmssfff") + "_" + Guid.NewGuid().ToString("N");
}

filename1 = GenerateFileName("MeasurementData");
filename2 = GenerateFileName("Image");

This way, when I sort by filename, it will automatically group the files by the context string and sort by timestamp.

Note that the filename limit in windows is 255 characters.

Quick Fix

Recalculating the length of the elements in serialized array - but don't use (preg_replace) it's deprecated - better use preg_replace_callback:

Edit: New Version now not just wrong length but it also fix line-breaks and count correct characters with aczent (thanks to mickmackusa)

// New Version
$data = preg_replace_callback('!s:\d+:"(.*?)";!s', function($m) { return "s:" . strlen($m[1]) . ':"'.$m[1].'";'; }, $data);

SNS is a distributed publish-subscribe system. Messages are pushed to subscribers as and when they are sent by publishers to SNS.

SQS is distributed queuing system. Messages are not pushed to receivers. Receivers have to poll or pull messages from SQS. Messages can't be received by multiple receivers at the same time. Any one receiver can receive a message, process and delete it. Other receivers do not receive the same message later. Polling inherently introduces some latency in message delivery in SQS unlike SNS where messages are immediately pushed to subscribers. SNS supports several end points such as email, SMS, HTTP end point and SQS. If you want unknown number and type of subscribers to receive messages, you need SNS.

You don't have to couple SNS and SQS always. You can have SNS send messages to email, SMS or HTTP end point apart from SQS. There are advantages to coupling SNS with SQS. You may not want an external service to make connections to your hosts (a firewall may block all incoming connections to your host from outside).

Your end point may just die because of heavy volume of messages. Email and SMS maybe not your choice of processing messages quickly. By coupling SNS with SQS, you can receive messages at your pace. It allows clients to be offline, tolerant to network and host failures. You also achieve guaranteed delivery. If you configure SNS to send messages to an HTTP end point or email or SMS, several failures to send message may result in messages being dropped.

SQS is mainly used to decouple applications or integrate applications. Messages can be stored in SQS for a short duration of time (maximum 14 days). SNS distributes several copies of messages to several subscribers. For example, let’s say you want to replicate data generated by an application to several storage systems. You could use SNS and send this data to multiple subscribers, each replicating the messages it receives to different storage systems (S3, hard disk on your host, database, etc.).

My solution:

First create "<style>" tags with an ID.

<style id="YourID">
    .YourClass {background-color:red}
</style>

Then, I create a function in JavaScript like this:

document.getElementById('YourID').innerHTML = '.YourClass {background-color:blue}'

Worked like a charm for me.

You can use JavaScript to do what you want:

if (document.addEventListener !== undefined) {
  // Not IE
  document.addEventListener('click', checkSelection, false);
} else {
  // IE
  document.attachEvent('onclick', checkSelection);
}

function checkSelection() {
    var sel = {};
    if (window.getSelection) {
        // Mozilla
        sel = window.getSelection();
    } else if (document.selection) {
        // IE
        sel = document.selection.createRange();
    }

    // Mozilla
    if (sel.rangeCount) {
        sel.removeAllRanges();
        return;
    }

    // IE
    if (sel.text > '') {
        document.selection.empty();
        return;
    }
}

Soap box: You really shouldn't be screwing with the client's user agent in this manner. If the client wants to select things on the document, then they should be able to select things on the document. It doesn't matter if you don't like the highlight color, because you aren't the one viewing the document.

I stumbled upon this old listing pondering this same question. My band-aid for this same question was to make my header text into a link. I then changed the color and removed text decoration with CSS. Now to make the entire header picture a link, I expanded the padding of the anchor tag until it reached close to the edge of the header image.... This worked to my satisfaction, and I figured i would share.

There is a simple and smart way like this:

echo "add:sfff" | xargs -d: -i  echo {}

But you must use gnu xargs, BSD xargs cant support -d delim. If you use apple mac like me. You can install gnu xargs :

brew install findutils

then

echo "add:sfff" | gxargs -d: -i  echo {}

You should be able to generate your own button code here: http://developers.facebook.com/docs/reference/plugins/like/

If you use AngularJs ngModel directive, remember that the value of value attribute does not bind on ngModel field.You have to init it by yourself and the best way to do it,is

<input type="text"
       id="rootFolder"
       ng-init="rootFolders = 'Bob'"
       ng-model="rootFolders"
       disabled="disabled"
       value="Bob"
       size="40"/>

This happened to me, I tried all the possible solutions with no luck!

Finaly I realized that the problem was with Jupyter notebook environment, not with sklearn!

I solved the problem by re-installing Jupyter at the same environment as sklearn

the command is: conda install -c anaconda ipython. Done...

To force the download of a PDF file, instead of being handled by the browser's PDF plugin:

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf", "MyRenamedFile.pdf");
}

If you want to let the browser handle by its default behavior (plugin or download), just send two parameters.

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf");
}

You'll need to use the third parameter to specify a name for the file on the browser dialog.

UPDATE: Charlino is right, when passing the third parameter (download filename) Content-Disposition: attachment; gets added to the Http Response Header. My solution was to send application\force-download as the mime-type, but this generates a problem with the filename of the download so the third parameter is required to send a good filename, therefore eliminating the need to force a download.

Answer to the original question:

os.urandom(n)

Quote from: http://docs.python.org/2/library/os.html

Return a string of n random bytes suitable for cryptographic use.

This function returns random bytes from an OS-specific randomness source. The returned data should be unpredictable enough for cryptographic applications, though its exact quality depends on the OS implementation. On a UNIX-like system this will query /dev/urandom, and on Windows it will use CryptGenRandom. If a randomness source is not found, NotImplementedError will be raised.

For an easy-to-use interface to the random number generator provided by your platform, please see random.SystemRandom.

I don't know if I understand your question, but maybe:

foreach ($_POST as $id=>$value)
    if (strncmp($id,'id[',3) $info[rtrim(ltrim($id,'id['),']')]=$_POST[$id];

would help

That is if you really want to have a different name (id[key]) on each checkbox of the html form (not very efficient). If not you can just name them all the same, i.e. 'id' and iterate on the (selected) values of the array, like: foreach ($_POST['id'] as $key=>$value)...

In VScode, they call this Copy Line Up and Copy Line Down

From the menu, go to:

File > Preferences > Keyboard Shortcuts

Check already assigned keyboard shortcut for this, or adjust yours.

Sometimes the default assigned shortcut may not work, mostly because of OS.

In my Ubuntu, I adjusted this to: Ctrl+Shift+D

Some of this seems "incomplete"

Groups of people are NOT going to know if they should use quotes etc..

Add 1 specific file showing the location paths as well

git add JobManager/Controllers/APIs/ProfileApiController.cs

Commit (remember, commit is local only, it is not affecting any other system)

git commit -m "your message"  

Push to remote repo

git push  (this is after the commit and this attempts to Merge INTO the remote location you have instructed it to merge into)

Other answer(s) show the stash etc. which you sometimes will want to do

You can use a deadlock graph and gather the information you require from the log file.

The only other way I could suggest is digging through the information by using EXEC SP_LOCK (Soon to be deprecated), EXEC SP_WHO2 or the sys.dm_tran_locks table.

SELECT  L.request_session_id AS SPID, 
    DB_NAME(L.resource_database_id) AS DatabaseName,
    O.Name AS LockedObjectName, 
    P.object_id AS LockedObjectId, 
    L.resource_type AS LockedResource, 
    L.request_mode AS LockType,
    ST.text AS SqlStatementText,        
    ES.login_name AS LoginName,
    ES.host_name AS HostName,
    TST.is_user_transaction as IsUserTransaction,
    AT.name as TransactionName,
    CN.auth_scheme as AuthenticationMethod
FROM    sys.dm_tran_locks L
    JOIN sys.partitions P ON P.hobt_id = L.resource_associated_entity_id
    JOIN sys.objects O ON O.object_id = P.object_id
    JOIN sys.dm_exec_sessions ES ON ES.session_id = L.request_session_id
    JOIN sys.dm_tran_session_transactions TST ON ES.session_id = TST.session_id
    JOIN sys.dm_tran_active_transactions AT ON TST.transaction_id = AT.transaction_id
    JOIN sys.dm_exec_connections CN ON CN.session_id = ES.session_id
    CROSS APPLY sys.dm_exec_sql_text(CN.most_recent_sql_handle) AS ST
WHERE   resource_database_id = db_id()
ORDER BY L.request_session_id

there any rule I can follow to be sure that my app executes my own code just in the main thread?

Typically you wouldn't need to do anything to ensure this — your list of things is usually enough. Unless you're interacting with some API that happens to spawn a thread and run your code in the background, you'll be running on the main thread.

If you want to be really sure, you can do things like

[self performSelectorOnMainThread:@selector(myMethod:) withObject:anObj waitUntilDone:YES];

to execute a method on the main thread. (There's a GCD equivalent too.)

Either way will add an entity to a PersistenceContext, the difference is in what you do with the entity afterwards.

Persist takes an entity instance, adds it to the context and makes that instance managed (ie future updates to the entity will be tracked).

Merge returns the managed instance that the state was merged to. It does return something what exists in PersistenceContext or creates a new instance of your entity. In any case, it will copy the state from the supplied entity, and return managed copy. The instance you pass in will not be managed (any changes you make will not be part of the transaction - unless you call merge again). Though you can use the returned instance (managed one).

Maybe a code example will help.

MyEntity e = new MyEntity();

// scenario 1
// tran starts
em.persist(e); 
e.setSomeField(someValue); 
// tran ends, and the row for someField is updated in the database

// scenario 2
// tran starts
e = new MyEntity();
em.merge(e);
e.setSomeField(anotherValue); 
// tran ends but the row for someField is not updated in the database
// (you made the changes *after* merging)
      
// scenario 3
// tran starts
e = new MyEntity();
MyEntity e2 = em.merge(e);
e2.setSomeField(anotherValue); 
// tran ends and the row for someField is updated
// (the changes were made to e2, not e)

Scenario 1 and 3 are roughly equivalent, but there are some situations where you'd want to use Scenario 2.

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

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

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

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

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

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

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

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

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

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

First thing to understand is that the RequestMapping#produces() element in

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")

serves only to restrict the mapping for your request handlers. It does nothing else.

Then, given that your method has a return type of String and is annotated with @ResponseBody, the return value will be handled by StringHttpMessageConverter which sets the Content-type header to text/plain. If you want to return a JSON string yourself and set the header to application/json, use a return type of ResponseEntity (get rid of @ResponseBody) and add appropriate headers to it.

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<String> bar() {
    final HttpHeaders httpHeaders= new HttpHeaders();
    httpHeaders.setContentType(MediaType.APPLICATION_JSON);
    return new ResponseEntity<String>("{\"test\": \"jsonResponseExample\"}", httpHeaders, HttpStatus.OK);
}

Note that you should probably have

<mvc:annotation-driven /> 

in your servlet context configuration to set up your MVC configuration with the most suitable defaults.

You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?

Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.

You can't do this: {this.state.arrayFromJson} As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map to do that.

I am pasting a link from where you can learn how to render elements from an array with React.

Hope it helps!

This is how I've added a bot to my channel and set up notifications:

1. Make sure the channel is public (you can set it private later)
2. Add administrators > Type the bot username and make it administrator
3. Your bot will join your channel
4. set a channel id by setting the channel url like

telegram.me/whateverIWantAndAvailable

the channel id will be @whateverIWantAndAvailable

Now set up your bot to send notifications by pusshing the messages here:

https://api.telegram.org/botTOKENOFTHEBOT/sendMessage?chat_id=@whateverIWantAndAvailable&text=Test

the message which bot will notify is: Test

I strongly suggest an urlencode of the message like

https://api.telegram.org/botTOKENOFTHEBOT/sendMessage?chat_id=@whateverIWantAndAvailable&text=Testing%20if%20this%20works

in php you can use urlencode("Test if this works"); in js you can encodeURIComponent("Test if this works");

I hope it helps

The humble for command has accumulated some interesting capabilities over the years:

D:\> FOR /F "delims=" %i IN ('date /t') DO set today=%i
D:\> echo %today%
Sat 20/09/2008

Note that "delims=" overwrites the default space and tab delimiters so that the output of the date command gets gobbled all at once.

To capture multi-line output, it can still essentially be a one-liner (using the variable lf as the delimiter in the resulting variable):

REM NB:in a batch file, need to use %%i not %i
setlocal EnableDelayedExpansion
SET lf=-
FOR /F "delims=" %%i IN ('dir \ /b') DO if ("!out!"=="") (set out=%%i) else (set out=!out!%lf%%%i)
ECHO %out%

To capture a piped expression, use ^|:

FOR /F "delims=" %%i IN ('svn info . ^| findstr "Root:"') DO set "URL=%%i"

fmod(x, y) is the function you use.

Just change the directory to another one and come back. Probably that one has been deleted or moved.

Maybe your network is slow, so that jar isn't downloaded completely.

There are two methods:

a. find your .m2 folder, you can find some path like this 'org/apache/maven/plugins/maven-resources-plugin', you need only delete this foldler 'maven-resources-plugin', because others are downloaded well.

Then maven build your project.

If other problem occures, repeat this process again.

b. you can change a more quick maven source.

Firstly, you should find maven's settings file(window ->prefernces -> maven -> user settings). If it is empty, you can create a new one (any path, for example, .m2/settings).

Secondly, add sth like this (From https://blog.csdn.net/liangyihuai/article/details/57406870). This example uses aliyun's maven.

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                          https://maven.apache.org/xsd/settings-1.0.0.xsd">

      <mirrors>
        <mirror>  
            <id>alimaven</id>  
            <name>aliyun maven</name>  
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
            <mirrorOf>central</mirrorOf>          
        </mirror>  
      </mirrors>
</settings>

Thirdly, maven build again. (before this, you should delete your .m2 folder's files)

If the size of the string is fixed, you might find easier to use an array of chars. If you have to do this a lot, it will be a tiny bit faster too.

char[] chars = new char[3];
chars[0] = 'i';
chars[1] = 'c';
chars[2] = 'e';
return new String(chars);

Also, I noticed in your original question, you use the Char class. If your chars are not nullable, it is better to use the lowercase char type.

Since no one has shared a neat two liner, I will share my own:

logging.basicConfig(filename='logs.log', level=logging.DEBUG, format="%(asctime)s:%(levelname)s: %(message)s")
logging.getLogger().addHandler(logging.StreamHandler())

I'm surprised that no one seems to have pointed out that one can pass a dictionary of keyed argument parameters, that satisfy the formal parameters, like so.

>>> def func(a='a', b='b', c='c', **kwargs):
...    print 'a:%s, b:%s, c:%s' % (a, b, c)
... 
>>> func()
a:a, b:b, c:c
>>> func(**{'a' : 'z', 'b':'q', 'c':'v'})
a:z, b:q, c:v
>>> 

For the correct solution after many hours:

1. Open the configuration file
2. Change the connection string with the following

<add name="umbracoDbDSN" connectionString="data source=YOUR_SERVER_NAME;database=nrc;Integrated Security=SSPI;persist security info=True;" providerName="System.Data.SqlClient" />

3. Change the YOUR_SERVER_NAME with your current server name and save
4. Open the IIS Manager
5. Find the name of the application pool that the website or web application is using
6. Right-click and choose Advanced settings
7. From Advanced settings under Process Model change the Identity to Custom account and add your Server Admin details, please see the attached images:

Hope this will help.

Since ASP.NET MVC 3, you can use:

@Html.Raw(myString)

Tips and tricks

less

Why are you using editors to just look at a (large) file?

Under *nix or Cygwin, just use less. (There is a famous saying – "less is more, more or less" – because "less" replaced the earlier Unix command "more", with the addition that you could scroll back up.) Searching and navigating under less is very similar to Vim, but there is no swap file and little RAM used.

There is a Win32 port of GNU less. See the "less" section of the answer above.

Perl

Perl is good for quick scripts, and its .. (range flip-flop) operator makes for a nice selection mechanism to limit the crud you have to wade through.

For example:

$ perl -n -e 'print if ( 1000000 .. 2000000)' humongo.txt | less

This will extract everything from line 1 million to line 2 million, and allow you to sift the output manually in less.

Another example:

$ perl -n -e 'print if ( /regex one/ .. /regex two/)' humongo.txt | less

This starts printing when the "regular expression one" finds something, and stops when the "regular expression two" find the end of an interesting block. It may find multiple blocks. Sift the output...

logparser

This is another useful tool you can use. To quote the Wikipedia article:

logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, a Microsoft employee, to automate tests for IIS logging. It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools. The default behavior of logparser works like a "data processing pipeline", by taking an SQL expression on the command line, and outputting the lines containing matches for the SQL expression.

Microsoft describes Logparser as a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows operating system such as the Event Log, the Registry, the file system, and Active Directory. The results of the input query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

Example usage:

C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line > 1000 and line < 2000"
C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line like '%pattern%'"

The relativity of sizes

100 MB isn't too big. 3 GB is getting kind of big. I used to work at a print & mail facility that created about 2% of U.S. first class mail. One of the systems for which I was the tech lead accounted for about 15+% of the pieces of mail. We had some big files to debug here and there.

And more...

Feel free to add more tools and information here. This answer is community wiki for a reason! We all need more advice on dealing with large amounts of data...

The simplest way to get equal height columns, without the ugly side effects that come along with absolute positioning, is to use the display: table properties:

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: table;
}

.div2, .div3 {
  display: table-cell;
}
.div2 {
  width:150px;
  height:auto;
  background-color: #F4A460;  

}
.div3 {
  width:150px;
  height:auto;
  background-color: #FFFFE0;  
}

http://jsfiddle.net/E4Zgj/21/

Now, if your goal is to have .div2 so that it is only as tall as it needs to be to contain its content while .div3 is at least as tall as .div2 but still able to expand if its content makes it taller than .div2, then you need to use flexbox. Flexbox support isn't quite there yet (IE10, Opera, Chrome. Firefox follows an old spec, but is following the current spec soon).

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: flex;
  align-items: flex-start;
}

.div2 {
  width:150px;
  background-color: #F4A460;
}

.div3 {
  width:150px;
  background-color: #FFFFE0;
  align-self: stretch;
}

Ultimately you want to review the datetime documentation and become familiar with the formatting variables, but here are some examples to get you started:

import datetime

print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Date now: %s' % datetime.datetime.now())
print('Date today: %s' % datetime.date.today())

today = datetime.date.today()
print("Today's date is {:%b, %d %Y}".format(today))

schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'
schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'
print('Maintenance: %s' % schedule)
print('Maintenance: %s' % schedule2)

The output:

Timestamp: 2014-10-18 21:31:12

Timestamp: 2014-Oct-18 21:31:12

Date now: 2014-10-18 21:31:12.318340

Date today: 2014-10-18

Today's date is Oct, 18 2014

Maintenance: Oct, 18 2014 - 6 PM to 10 PM Pacific

Maintenance: October, 18 2014 - 1 PM to 6 PM Central

The [] makes no sense in the moment of making an ArrayList of Integers because I imagine you just want to add Integer values. Just use

List<Integer> list = new ArrayList<>();

to create the ArrayList and it will work.

You can use numpy.linalg.lstsq

You can do it with a table, like this:

<table width="100%">
  <tr>
    <td style="width: 50%">Left Text</td>
    <td style="width: 50%; text-align: right;">Right Text</td>
  </tr>
</table>

Or, you can do it with CSS like this:

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

Your live apps will not be taken down. Nothing will happen to anything that is live in the app store.

Once they formally expire, the only thing that will be impacted is your ability to sign code (and thus make new builds and provide updates).

Regarding your distribution certificate, once it expires, it simply disappears from the ‘Certificates, Identifier & Profiles’ section of Member Center. If you want to renew it before it expires, revoke the current certificate and you will get a button to request a new one.

Regarding the provisioning profile, don't worry about it before expiration, just keep using it. It's easy enough to just renew it once it expires.

The peace of mind is that nothing will happen to your live app in the store.

When you install python for windows, there is an option to include it in the path. For python 2 this is not the default. It adds the python installation folder and script folder to the Windows path. When starting the GIT Bash command prompt, it have included it in the linux PATH variable.

If you start the python installation again, you should select the option Change python and in the next step you can "Add python.exe to Path". Next time you open GIT Bash, the path is correct.

Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885

This doesn't rely on serialization nor on content negotiation.

[HttpGet]
public ContentResult Index() {
    return new ContentResult {
        ContentType = "text/html",
        StatusCode = (int)HttpStatusCode.OK,
        Content = "<html><body>Hello World</body></html>"
    };
}

Try C# string interpolation introduced in C# 6:

var id = 100;
var hexid = $"0x{id:X}";

hexid value:

"0x64"

The array decays to a pointer when passed.

Section 6.4 of the C FAQ covers this very well and provides the K&R references etc.

That aside, imagine it were possible for the function to know the size of the memory allocated in a pointer. You could call the function two or more times, each time with different input arrays that were potentially different lengths; the length would therefore have to be passed in as a secret hidden variable somehow. And then consider if you passed in an offset into another array, or an array allocated on the heap (malloc and all being library functions - something the compiler links to, rather than sees and reasons about the body of).

Its getting difficult to imagine how this might work without some behind-the-scenes slice objects and such right?

Symbian did have a AllocSize() function that returned the size of an allocation with malloc(); this only worked for the literal pointer returned by the malloc, and you'd get gobbledygook or a crash if you asked it to know the size of an invalid pointer or a pointer offset from one.

You don't want to believe its not possible, but it genuinely isn't. The only way to know the length of something passed into a function is to track the length yourself and pass it in yourself as a separate explicit parameter.

In case you want the left and right elements to wrap content but have the middle space

<LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
    <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"/>
    <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
</LinearLayout>

To support the answer by @oberstet, if the cert is not trusted by the browser (for example you get a "this site is not secure, do you want to continue?") one solution is to open the browser options, navigate to the certificates settings and add the host and post that the websocket server is being served from to the certificate provider as an exception.

for example add 'example-wss-domain.org:6001' as an exception to 'Certificate Provider Ltd'.

In firefox, this can be done from 'about:preferences' and searching for 'Certificates'

It looks like your PHP installation does not have the mbstring extension and the mysqli adapter extension installed.

Please check your phpinfo(); or run php -i | grep 'mbstring\|mysqli' in a terminal.

If you just want to select the used range, use

ActiveSheet.UsedRange.Select

If you want to select from A1 to the end of the used range, you can use the SpecialCells method like this

With ActiveSheet
    .Range(.Cells(1, 1), .Cells.SpecialCells(xlCellTypeLastCell)).Select
End With

Sometimes Excel gets confused on what is the last cell. It's never a smaller range than the actual used range, but it can be bigger if some cells were deleted. To avoid that, you can use Find and the asterisk wildcard to find the real last cell.

Dim rLastCell As Range

With Sheet1
    Set rLastCell = .Cells.Find("*", .Cells(1, 1), xlValues, xlPart, , xlPrevious)

    .Range(.Cells(1, 1), rLastCell).Select
End With

Finally, make sure you're only selecting if you really need to. Most of what you need to do in Excel VBA you can do directly to the Range rather than selecting it first. Instead of

.Range(.Cells(1, 1), rLastCell).Select
Selection.Font.Bold = True

You can

.Range(.Cells(1,1), rLastCells).Font.Bold = True

Shouldn't be hard to test, create a function that switches or ifelse's between 5 numbers, throw a rand(1,5) into that function and loop that a few times while timing it.

One-liner:

bytearray.fromhex('{:0192x}'.format(big_int))

The 192 is 768 / 4, because OP wanted 768-bit numbers and there are 4 bits in a hex digit. If you need a bigger bytearray use a format string with a higher number. Example:

[My answer had used hex() before. I corrected it with format() in order to handle ints with odd-sized byte expressions. This fixes previous complaints about ValueError.]

You say you "really just want B", but this is false. You want B, but you also want an updated A if there have been any changes to it ("active development").

So, sometimes you want to work with A, B, and C. For this case you have aggregator project P. For the case where you want to work with A and B (but do not want C), you should create aggregator project Q.

Edit 2016: The above information was perhaps relevant in 2009. As of 2016, I highly recommend ignoring this in most cases, and simply using the -am or -pl command-line flags as described in the accepted answer. If you're using a version of maven from before v2.1, change that first :)

A bit late to the party but you can also use a context manager, if you're opening and closing your file multiple times, or logging data, statistics, etc.

from contextlib import contextmanager
import pandas as pd
@contextmanager
def open_file(path, mode):
     file_to=open(path,mode)
     yield file_to
     file_to.close()


##later
saved_df=pd.DataFrame(data)
with open_file('yourcsv.csv','r') as infile:
      saved_df.to_csv('yourcsv.csv',mode='a',header=False)`

For those using yarn.

I tried using npm shrinkwrap until I discovered the yarn cli ignored my npm-shrinkwrap.json file.

Yarn has https://yarnpkg.com/lang/en/docs/selective-version-resolutions/ for this. Neat.

Check out this answer too: https://stackoverflow.com/a/41082766/3051080

Try this, to make sure you configured CORS correctly:

[EnableCors(origins: "*", headers: "*", methods: "*")]

Still not working? Check HTTP headers presence.

Yes, s stands for string. The json.loads function does not take the file path, but the file contents as a string. Look at the documentation at https://docs.python.org/2/library/json.html!

this is the only one that really works:

me?fields=picture.type(*YOURTYPE*)

where YOURTYPE can be one of the following: small, normal, album, large, square

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

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

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

One way would be to delete the local branch and checkout that branch from the server if your local branch is ahead of remote by multiple commits and you need to uncommit all of them.

The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:

public class child : parent {
    public child(int i) : base(i) {
        Console.WriteLine("child");
    }
}

Just like everyone else said, you can't control border height. But there are workarounds, here's what I do:

table {
  position: relative;
}

table::before { /* ::after works too */
  content: "";
  position: absolute;
  right: 0; /* Change direction for a different side*/
  z-index: 100; 
  width: 3px; /* Thickness */
  height: 10px;
  background: #555; /* Color */
}

You can set height to inherit for the height of the table or calc(inherit - 2px) for a 2px smaller border. Remember, inherit has no effect when the table height isn't set.

Use height: 50% for half a border.

Demo

Using NOT EXISTS:

INSERT INTO TABLE_2
  (id, name)
SELECT t1.id,
       t1.name
  FROM TABLE_1 t1
 WHERE NOT EXISTS(SELECT id
                    FROM TABLE_2 t2
                   WHERE t2.id = t1.id)

Using NOT IN:

INSERT INTO TABLE_2
  (id, name)
SELECT t1.id,
       t1.name
  FROM TABLE_1 t1
 WHERE t1.id NOT IN (SELECT id
                       FROM TABLE_2)

Using LEFT JOIN/IS NULL:

INSERT INTO TABLE_2
  (id, name)
   SELECT t1.id,
          t1.name
     FROM TABLE_1 t1
LEFT JOIN TABLE_2 t2 ON t2.id = t1.id
    WHERE t2.id IS NULL

Of the three options, the LEFT JOIN/IS NULL is less efficient. See this link for more details.

It works for me thank you. I had this issue when I installed .Net Framework 4.7.1, somehow DbProviderFactories settings under System.Data in machine config got wiped-out. It started working after adding the necessary configuration settings as shown below DataProviderFactories

<system.data>
    <DbProviderFactories>
      <add name="Oracle Data Provider for .NET" invariant="Oracle.DataAccess.Client" description="Oracle Data Provider for .NET" type="Oracle.DataAccess.Client.OracleClientFactory, Oracle.DataAccess, Version=4.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342"/>

    </DbProviderFactories>
</system.data>

Just a note, if you ever see this:

a = x ? : y;

It's a GNU extension to the standard (see https://gcc.gnu.org/onlinedocs/gcc/Conditionals.html#Conditionals).

It is the same as

a = x ? x : y;

string str="This is test string.";
str=str.Remove(str.Length-1);

As Scobal's post implies, the datepicker is looking for a Date object - not just a string! So, to modify your example code to do what you want:

var queryDate = new Date('2009/11/01'); // Dashes won't work
$('#datePicker').datepicker('setDate', queryDate);

The answer as well as other answers are correct. I am going to add to those answers with a solution that I think will be helpful. I think this comes up often in programming. One thing to note is that for Collections (Lists, Sets, etc.) the main issue is adding to the Collection. That is where things break down. Even removing is OK.

In most cases, we can use Collection<? extends T> rather then Collection<T> and that should be the first choice. However, I am finding cases where it is not easy to do that. It is up for debate as to whether that is always the best thing to do. I am presenting here a class DownCastCollection that can take convert a Collection<? extends T> to a Collection<T> (we can define similar classes for List, Set, NavigableSet,..) to be used when using the standard approach is very inconvenient. Below is an example of how to use it (we could also use Collection<? extends Object> in this case, but I am keeping it simple to illustrate using DownCastCollection.

/**Could use Collection<? extends Object> and that is the better choice. 
* But I am doing this to illustrate how to use DownCastCollection. **/

public static void print(Collection<Object> col){  
    for(Object obj : col){
    System.out.println(obj);
    }
}
public static void main(String[] args){
  ArrayList<String> list = new ArrayList<>();
  list.addAll(Arrays.asList("a","b","c"));
  print(new DownCastCollection<Object>(list));
}

Now the class:

import java.util.AbstractCollection;
import java.util.Collection;
import java.util.Iterator;
import java.util.NoSuchElementException;

public class DownCastCollection<E> extends AbstractCollection<E> implements Collection<E> {
private Collection<? extends E> delegate;

public DownCastCollection(Collection<? extends E> delegate) {
    super();
    this.delegate = delegate;
}

@Override
public int size() {
    return delegate ==null ? 0 : delegate.size();
}

@Override
public boolean isEmpty() {
    return delegate==null || delegate.isEmpty();
}

@Override
public boolean contains(Object o) {
    if(isEmpty()) return false;
    return delegate.contains(o);
}
private class MyIterator implements Iterator<E>{
    Iterator<? extends E> delegateIterator;

    protected MyIterator() {
        super();
        this.delegateIterator = delegate == null ? null :delegate.iterator();
    }

    @Override
    public boolean hasNext() {
        return delegateIterator != null && delegateIterator.hasNext();
    }

    @Override
    public  E next() {
        if(!hasNext()) throw new NoSuchElementException("The iterator is empty");
        return delegateIterator.next();
    }

    @Override
    public void remove() {
        delegateIterator.remove();

    }

}
@Override
public Iterator<E> iterator() {
    return new MyIterator();
}



@Override
public boolean add(E e) {
    throw new UnsupportedOperationException();
}

@Override
public boolean remove(Object o) {
    if(delegate == null) return false;
    return delegate.remove(o);
}

@Override
public boolean containsAll(Collection<?> c) {
    if(delegate==null) return false;
    return delegate.containsAll(c);
}

@Override
public boolean addAll(Collection<? extends E> c) {
    throw new UnsupportedOperationException();
}

@Override
public boolean removeAll(Collection<?> c) {
    if(delegate == null) return false;
    return delegate.removeAll(c);
}

@Override
public boolean retainAll(Collection<?> c) {
    if(delegate == null) return false;
    return delegate.retainAll(c);
}

@Override
public void clear() {
    if(delegate == null) return;
        delegate.clear();

}

}

NOTE:

The method used in this answer (backticks) is deprecated in later versions of Python 2, and removed in Python 3. Use the str() function instead.

You can use :

string = 'string'
for i in range(11):
    string +=`i`
print string

It will print string012345678910.

To get string0, string1 ..... string10 you can use this as @YOU suggested

>>> string = "string"
>>> [string+`i` for i in range(11)]

Update as per Python3

You can use :

string = 'string'
for i in range(11):
    string +=str(i)
print string

It will print string012345678910.

To get string0, string1 ..... string10 you can use this as @YOU suggested

>>> string = "string"
>>> [string+str(i) for i in range(11)]

@freelancer If you are using ScriptManager then try this code for message..

string script = "alert(\"Hello!\");";
ScriptManager.RegisterStartupScript(this, GetType(), 
                      "ServerControlScript", script, true);

It appears I cannot use an if statement.

Arrow functions either allow to use an expression or a block as their body. Passing an expression

foo => bar

is equivalent to the following block

foo => { return bar; }

However,

if (person.age > 18) person

is not an expression, if is a statement. Hence you would have to use a block, if you wanted to use if in an arrow function:

foo => {  if (person.age > 18) return person; }

While that technically solves the problem, this a confusing use of .filter, because it suggests that you have to return the value that should be contained in the output array. However, the callback passed to .filter should return a Boolean, i.e. true or false, indicating whether the element should be included in the new array or not.

So all you need is

family.filter(person => person.age > 18);

In ES5:

family.filter(function (person) {
  return person.age > 18;
});

There is no unique method for a df, if the number of unique values for each column were the same then the following would work: df.apply(pd.Series.unique) but if not then you will get an error. Another approach would be to store the values in a dict which is keyed on the column name:

In [111]:
df = pd.DataFrame({'a':[0,1,2,2,4], 'b':[1,1,1,2,2]})
d={}
for col in df:
    d[col] = df[col].unique()
d

Out[111]:
{'a': array([0, 1, 2, 4], dtype=int64), 'b': array([1, 2], dtype=int64)}

I just ran into that issue and after all the explanations about fixing it with command prompt I found that if you add it directly to the project you can then simply include the library on each page that it's needed

$.post('someUri', { }, 
  function(data){ doSomeStuff })
 .fail(function(error) { alert(error.responseJSON) });

below code is working for both with header and without header to print log request & response. Note: Just comment .addHeader() line if are not using header.

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(interceptor)
                //.addInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR)
                .addNetworkInterceptor(new Interceptor() {

                    @Override

                    public okhttp3.Response intercept(Chain chain) throws IOException {
                        Request request = chain.request().newBuilder()
                                // .addHeader(Constant.Header, authToken)
                                   .build();
                        return chain.proceed(request);
                    }
                }).build();

        final Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Constant.baseUrl)
                .client(client) // This line is important
                .addConverterFactory(GsonConverterFactory.create())
                .build();

[tableview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO];

This will take your tableview to the first row.

Transferring files with Putty (pscp/plink.exe)

The default putty installation provides multiple ways to transfer files. Most likely putty is on your default path, so you can directly call putty from the command prompt. If it doesnt, you may have to change your environmental variables. See instructions here: https://it.cornell.edu/managed-servers/transfer-files-using-putt

Steps

1. Open command prompt by typing cmd

2. To transfer folders from your Windows computer to another Windows computer use (notice the -r flag, which indicates that the files will be transferred recursively, no need to zip them up): pscp -r -i C:/Users/username/.ssh/id_rsa.ppk "C:/Program Files (x86)/Terminal PC" [email protected]:/"C:/Program Files (x86)/"

3. To transfer files from your Windows computer to another Windows computer use: pscp -i C:/Users/username/.ssh/id_rsa.ppk "C:/Program Files (x86)/Terminal PC" [email protected]:/"C:/Program Files (x86)/"

4. Sometimes, you may only have plink installed. plink can potentially be used to transfer files, but its best restricted to simple text files. It may have unknown behavior with binary files (https://superuser.com/questions/1289455/create-text-file-on-remote-machine-using-plink-putty-with-contents-of-windows-lo): plink -i C:/Users/username/.ssh/id_rsa.ppk user@host <localfile "cat >hostfile"

5. To transfer files from a linux server to a Windows computer to a Linux computer use pscp -r -i C:/Users/username/.ssh/id_rsa.ppk "C:/Program Files (x86)/Terminal PC" [email protected]:/home/username

For all these to work, you need to have the proper public/private key. To generate that for putty see: https://superuser.com/a/1285789/658319

Import moment js:

var fulldate = new Date(1370001284000);
var converted_date = moment(fulldate).format(");

You can use "translateX(-100%)" and "text-align: right" if your absolute element is "display: inline-block"

<div class="box">
<div class="absolute-right"></div>
</div>

<style type="text/css">
.box{
    text-align: right;
}
.absolute-right{
    display: inline-block;
    position: absolute;
}

/*The magic:*/
.absolute-right{
-moz-transform: translateX(-100%);
-ms-transform: translateX(-100%);
-webkit-transform: translateX(-100%);
-o-transform: translateX(-100%);
transform: translateX(-100%);
}
</style>

You will get absolute-element aligned to the right relative its parent

A solution combining find and replace methods in a single line if statement could be:

```python
my_var = "stackoverflaw"
my_new_var = my_var.replace('a', 'o', 1) if my_var.find('s') != -1 else my_var
print(f"my_var = {my_var}")           # my_var = stackoverflaw
print(f"my_new_var = {my_new_var}")   # my_new_var = stackoverflow
```

It is prohibiting the opening of Eclipse app because it was not registered with Apple by an identified developer. This is a security feature, however, you can override the security setting and open the app by doing the following:

1. Locate the Eclipse.app (eclipse/Eclipse.app) in Finder. (Make sure you use Finder so that you can perform the subsequent steps.)
2. Press the Control key and then click the Eclipse.app icon.
3. Choose Open from the shortcut menu.
4. Click the Open button when the alert window appears.

The last step will add an exception for Eclipse to your security settings and now you will be able to open it without any warnings.

Note, these steps work for other *.app apps that may encounter the same issue.

LIMIT 1 is what you want. Just keep in mind this returns the first record in the result set regardless of order (unless you specify an order clause in an outer query).

It is most accurate to say that methods with a Bang! are the more dangerous or surprising version. There are many methods that mutate without a Bang such as .destroy and in general methods only have bangs where a safer alternative exists in the core lib.

For instance, on Array we have .compact and .compact!, both methods mutate the array, but .compact! returns nil instead of self if there are no nil's in the array, which is more surprising than just returning self.

The only non-mutating method I've found with a bang is Kernel's .exit! which is more surprising than .exit because you cannot catch SystemExit while the process is closing.

Rails and ActiveRecord continues this trend in that it uses bang for more 'surprising' effects like .create! which raises errors on failure.

Class.getSimpleName()

Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

It is actually stripping the package information from the name, but this is hidden from you.

If response is an Array Buffer, try this under onsuccess event in Ajax:

 if (event.data instanceof ArrayBuffer) {
          var binary = '';
          var bytes = new Uint8Array(event.data);
          for (var i = 0; i < bytes.byteLength; i++) {
              binary += String.fromCharCode(bytes[i])
          }
          $("#some_id").append("<li><img src=\"data:image/png;base64," + window.btoa(binary) + "\"/></span></li>");
          return;
      }

• where event.data is response received in success function of xhr event.

I would agree with most of the answers saying that its a browser settings but still you can achieve what you want via COM. Keep in mind that most browsers will still have issue with that and even IE will raise the COM security bar to users. So unless its not something you are offering within organisation, don't do it.

Do not use '*' for Origin, until You really need a completely public behavior.
As Wikipedia says:

"The value of "*" is special in that it does not allow requests to supply credentials, meaning HTTP authentication, client-side SSL certificates, nor does it allow cookies to be sent."

That means, you'll get a lot of errors, especially in Chrome when you'll try to implement for example a simple authentication.

Here is a corrected wrapper:

// Code has not been tested.
func addDefaultHeaders(fn http.HandlerFunc) http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        if origin := r.Header.Get("Origin"); origin != "" {
            w.Header().Set("Access-Control-Allow-Origin", origin)
        }
        w.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
        w.Header().Set("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token")
        w.Header().Set("Access-Control-Allow-Credentials", "true")
        fn(w, r)
    }
}

And don't forget to reply all these headers to the preflight OPTIONS request.

Excerpt from PostgreSQL documentation:

Restricting and cascading deletes are the two most common options. [...] CASCADE specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.

This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE.

Example:

CREATE SCHEMA shire;

CREATE TABLE shire.clans (
    id serial PRIMARY KEY,
    clan varchar
);

CREATE TABLE shire.hobbits (
    id serial PRIMARY KEY,
    hobbit varchar,
    clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);

DELETE FROM clans will CASCADE to hobbits by REFERENCES.

sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
 id |    clan    
----+------------
  1 | Baggins
  2 | Gamgi
(2 rows)

sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  1 | Bilbo    |       1
  2 | Frodo    |       1
  3 | Samwise  |       2
(3 rows)

sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;
 id |  clan   
----+---------
  1 | Baggins
(1 row)

DELETE 1
sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  3 | Samwise  |       2
(1 row)

If you really need the opposite (checked by the database), you will have to write a trigger!

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

Addition

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/


DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823); 
SET @y2 = @y2 + @y2;
SELECT LEN(@y2), DATALENGTH(@y2)  /*2147483646, 4294967292*/


DECLARE @y3 NVARCHAR(MAX) = @y2 + @y1
SELECT LEN(@y3), DATALENGTH(@y3)   /*6442450940, 12884901880*/

/*This attempt fails*/

From here

The answer provided by polygenelubricants splits an array based on given size. I was looking for code that would split an array into a given number of parts. Here is the modification I did to the code:

        lsParts.add( new ArrayList<T>( ls.subList( i, Math.min( iT, i + iTake ) ) ) );
    }

    return lsParts;
}

Hope it helps someone.

You can use:

 echo '<?php if(function_exists("my_func")) echo "function exists"; ' | php

The short tag "< ?=" can be helpful too:

 echo '<?= function_exists("foo") ? "yes" : "no";' | php
 echo '<?= 8+7+9 ;' | php

The closing tag "?>" is optional, but don't forget the final ";"!

From Microsoft MSDN recommendations:

Application icons and Control Panel items: The full set includes 16x16, 32x32, 48x48, and 256x256 (code scales between 32 and 256). The .ico file format is required. For Classic Mode, the full set is 16x16, 24x24, 32x32, 48x48 and 64x64.

So we have already standard recommended sizes of:

• 16 x 16,
• 24 x 24,
• 32 x 32,
• 48 x 48,
• 64 x 64,
• 256 x 256.

If we would like to support high DPI settings, the complete list will include the following sizes as well:

• 20 x 20,
• 30 x 30,
• 36 x 36,
• 40 x 40,
• 60 x 60,
• 72 x 72,
• 80 x 80,
• 96 x 96,
• 128 x 128,
• 320 x 320,
• 384 x 384,
• 512 x 512.

I deleted the project without removing content. I then created a new Java project from an existing resource. Pointing at my SVN checkout root folder. This worked for me. Although, Chris' way would have been much quicker. That's good to note for future. Thanks!

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

The differences are listed in the Javadoc for ListIterator

You can

• iterate backwards
• obtain the iterator at any point.
• add a new value at any point.
• set a new value at that point.

The subversion client itself is available on Windows. See here for certified binaries from CollabNet.

CollabNet Subversion Command-Line Client v1.6.9 (for Windows)

This installer only includes the command-line client and an auto-update component.

Even though I can't understand it's possible not to love Tortoise! :)

Note:
The above link is for newer products - you can find version 1.11.1 through 1.7.19 at Older Subversion Releases

There is no way to do that as the author of the HTML that a browser renders. At least not yet that I know of. Its pretty much up to the browser and its settings / preferences that are set by users themselves.

Also, you shouldn't impose this upon any user. A browser is the user's property. If a user wants to open all links in tabs or in new windows, then let the user do exactly that.

It's good that we can't do certain things. target=_blank is still abused and popups have been done to death.

use .prop() to get the value of a property

$("#checkAll").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

Your query is probably fine. "The semaphore timeout period has expired" is a Network error, not a SQL Server timeout.

There is apparently some sort of network problem between you and the SQL Server.

edit: However, apparently the query runs for 15-20 min before giving the network error. That is a very long time, so perhaps the network error could be related to the long execution time. Optimization of the underlying View might help.

If [MyTable] in your example is a View, can you post the View Definition so that we can have a go at optimizing it?

To answer this question simply, C++ is a much more complex language than other languages available on the market. It has a legacy inclusion model that parses code multiple times, and its templated libraries are not optimized for compilation speed.

Grammar and ADL

Let's have a look at the grammatical complexity of C++ by considering a very simple example:

x*y;

While you’d be likely to say that the above is an expression with multiplication, this is not necessarily the case in C++. If x is a type, then the statement is, in fact, a pointer declaration. This means that C++ grammar is context-sensitive.

Here’s another example:

foo<x> a;

Again, you might think this is a declaration of the variable "a" of type foo, but it could also be interpreted as:

(foo < x) > a;

which would make it a comparison expression.

C++ has a feature called Argument Dependent Lookup (ADL). ADL establishes the rules that govern how the compiler looks up a name. Consider the following example:

namespace A{
  struct Aa{}; 
  void foo(Aa arg);
}
namespace B{
  struct Bb{};
  void foo(A::Aa arg, Bb arg2);
}
namespace C{ 
  struct Cc{}; 
  void foo(A::Aa arg, B::Bb arg2, C::Cc arg3);
}

foo(A::Aa{}, B::Bb{}, C::Cc{});

ADL rules state that we will be looking for the name "foo" considering all arguments of the function call. In this case, all of the functions named “foo” will be considered for overload resolution. This process might take time, especially if there are lots of function overloads. In a templated context, ADL rules become even more complicated.

#include

This command is something that might significantly influence compilation times. Depending on the type of file you include, the preprocessor might copy only a couple of lines of code, or it might copy thousands.

Furthermore, this command cannot be optimized by the compiler. You can copy different pieces of code that can be modified just before inclusion if the header file depends on macros.

There are some solutions to these issues. You can use precompiled headers, which are the compiler's internal representation of what was parsed in the header. This can’t be done without the user's effort, however, because precompiled headers assume that headers are not macro dependent.

The modules feature provides a language-level solution to this problem. It’s available from the C++20 release onward.

Templates

The compilation speed for templates is challenging. Each translation unit that uses templates needs to have them included, and the definitions of these templates need to be available. Some instantiations of templates end up in instantiations of other templates. In some extreme cases, template instantiation can consume lots of resources. A library that uses templates and that was not designed for compilation speed can become troublesome, as you can see in a comparison of metaprogramming libraries provided at this link: http://metaben.ch/. Their differences in compilation speed are significant.

If you want to understand why some metaprogramming libraries are better for compilation times than others, check out this video about the Rule of Chiel.

Conclusion

C++ is a slowly compiled language because compilation performance was not the highest priority when the language was initially developed. As a result, C++ ended up with features that might be effective during runtime, but are not necessarily effective during compile time.

P.S – I work at Incredibuild, a software development acceleration company specializing in accelerating C++ compilations, you are welcome to try it for free.

This worked for me

sudo apt install openjdk-8-jre-headless

I have a solution that works well for me. It consists of a local jenkins running in docker and a git web hook to trigger the pipeline in the local jenkins on every commit. You no longer need to push to your github or bitbucket repository to test the pipeline.

This has only been tested in a linux environment.

It is fairly simple to make this work although this instruction is a tad long. Most steps are there.

This is what you need

• Docker installed and working. This is not part of this instruction.
• A Jenkins running in docker locally. Explained how below.
  • The proper rights (ssh access key) for your local Jenkins docker user to pull from your local git repo. Explained how below.
  • A Jenkins pipeline project that pulls from your local git repository. Explained below.
  • A git user in your local Jenkins with minimal rights. Explained below.
• A git project with a post-commit web hook that triggers the pipeline project. Explained below.

This is how you do it

Jenkins Docker

Create a file called Dockerfile in place of your choosing. I'm placing it in /opt/docker/jenkins/Dockerfile fill it with this:

FROM jenkins/jenkins:lts
USER root
RUN apt-get -y update && apt-get -y upgrade
# Your needed installations goes here
USER jenkins

Build the local_jenkins image

This you will need to do only once or after you have added something to the Dockerfile.

$ docker build -t local_jenkins /opt/docker/jenkins/

Start and restart local_jenkins

From time to time you want to start and restart jenkins easily. E.g. after a reboot of your machine. For this I made an alias that I put in .bash_aliases in my home folder.

$ echo "alias localjenkinsrestart='docker stop jenkins;docker rm jenkins;docker run --name jenkins -i -d -p 8787:8080 -p 50000:50000 -v /opt/docker/jenkins/jenkins_home:/var/jenkins_home:rw local_jenkins'" >> ~/.bash_aliases
$ source .bash_aliases  # To make it work

Make sure the /opt/docker/jenkins/jenkins_home folder exists and that you have user read and write rights to it.

To start or restart your jenkins just type:

$ localjenkinsrestart

Everything you do in your local jenkins will be stored in the folder /opt/docker/jenkins/jenkins_home and preserved between restarts.

Create a ssh access key in your docker jenkins

This is a very important part for this to work. First we start the docker container and create a bash shell to it:

$ localjenkinsrestart
$ docker exec -it jenkins /bin/bash

You have now entered into the docker container, this you can see by something like jenkins@e7b23bad10aa:/$ in your terminal. The hash after the @ will for sure differ.

Create the key

jenkins@e7b23bad10aa:/$ ssh-keygen

Press enter on all questions until you get the prompt back

Copy the key to your computer. From within the docker container your computer is 172.17.0.1 should you wonder.

jenkins@e7b23bad10aa:/$ ssh-copy-id [email protected]

user = your username and 172.17.0.1 is the ip address to your computer from within the docker container.

You will have to type your password at this point.

Now lets try to complete the loop by ssh-ing to your computer from within the docker container.

jenkins@e7b23bad10aa:/$ ssh [email protected]

This time you should not need to enter you password. If you do, something went wrong and you have to try again.

You will now be in your computers home folder. Try ls and have a look.

Do not stop here since we have a chain of ssh shells that we need to get out of.

$ exit
jenkins@e7b23bad10aa:/$ exit

Right! Now we are back and ready to continue.

Install your Jenkins

You will find your local Jenkins in your browser at http://localhost:8787.

First time you point your browser to your local Jenkins your will be greated with a Installation Wizard. Defaults are fine, do make sure you install the pipeline plugin during the setup though.

Setup your jenkins

It is very important that you activate matrix based security on http://localhost:8787/configureSecurity and give yourself all rights by adding yourself to the matrix and tick all the boxes. (There is a tick-all-boxes icon on the far right)

• Select Jenkins’ own user database as the Security Realm
• Select Matrix-based security in the Authorization section
• Write your username in the field User/group to add: and click on the [ Add ] button
• In the table above your username should pop up with a people icon next to it. If it is crossed over you typed your username incorrectly.
• Go to the far right of the table and click on the tick-all-button or manually tick all the boxes in your row.
• Please verify that the checkbox Prevent Cross Site Request Forgery exploits is unchecked. (Since this Jenkins is only reachable from your computer this isn't such a big deal)
• Click on [ Save ] and log out of Jenkins and in again just to make sure it works. If it doesn't you have to start over from the beginning and emptying the /opt/docker/jenkins/jenkins_home folder before restarting

Add the git user

We need to allow our git hook to login to our local Jenkins with minimal rights. Just to see and build jobs is sufficient. Therefore we create a user called git with password login.

Direct your browser to http://localhost:8787/securityRealm/addUser and add git as username and login as password. Click on [ Create User ].

Add the rights to the git user

Go to the http://localhost:8787/configureSecurity page in your browser. Add the git user to the matrix:

• Write git in the field User/group to add: and click on [ Add ]

Now it is time to check the boxes for minimal rights to the git user. Only these are needed:

• overall:read
• job:build
• job:discover
• job:read

Make sure that the Prevent Cross Site Request Forgery exploits checkbox is unchecked and click on [ Save ]

Create the pipeline project

We assume we have the username user and our git enabled project with the Jenkinsfile in it is called project and is located at /home/user/projects/project

In your http://localhost:8787 Jenkins add a new pipeline project. I named it hookpipeline for reference.

• Click on New Item in the Jenkins menu
• Name the project hookpipeline
• Click on Pipeline
• Click [ OK ]
• Tick the checkbox Poll SCM in the Build Triggers section. Leave the Schedule empty.
• In the Pipeline section:
  • select Pipeline script from SCM
  • in the Repository URL field enter [email protected]:projects/project/.git
  • in the Script Path field enter Jenkinsfile
• Save the hookpipeline project
• Build the hookpipeline manually once, this is needed for the Poll SCM to start working.

Create the git hook

Go to the /home/user/projects/project/.git/hooks folder and create a file called post-commit that contains this:

#!/bin/sh
BRANCHNAME=$(git rev-parse --abbrev-ref HEAD)
MASTERBRANCH='master'

curl -XPOST -u git:login http://localhost:8787/job/hookpipeline/build
echo "Build triggered successfully on branch: $BRANCHNAME"

Make this file executable:

$ chmod +x /home/user/projects/project/.git/hooks/post-commit

Test the post-commit hook:

$ /home/user/projects/project/.git/hooks/post-commit

Check in Jenkins if your hookpipeline project was triggered.

Finally make some arbitrary change to your project, add the changes and do a commit. This will now trigger the pipeline in your local Jenkins.

Happy Days!

From Ian Bicking's own introduction to pip:

pip was originally written to improve on easy_install in the following ways

• All packages are downloaded before installation. Partially-completed installation doesn’t occur as a result.
• Care is taken to present useful output on the console.
• The reasons for actions are kept track of. For instance, if a package is being installed, pip keeps track of why that package was required.
• Error messages should be useful.
• The code is relatively concise and cohesive, making it easier to use programmatically.
• Packages don’t have to be installed as egg archives, they can be installed flat (while keeping the egg metadata).
• Native support for other version control systems (Git, Mercurial and Bazaar)
• Uninstallation of packages.
• Simple to define fixed sets of requirements and reliably reproduce a set of packages.

You can eliminate index.php from URL by create .htaccess file in the base directory of your porject, that file its content as

RewriteEngine on
RewriteCond $1 !^(index\.php|assets|images|js|css|uploads|favicon.png)
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ ./index.php/$1 [L]

save that file also your changed in config.php file is right

$config['index_page'] = '';

I wish to run successfully

I am on Mac OS Sierra. I had to update /etc/paths and add /Users/my.username/.rbenv/shims to the top of the list.

The character '\' is a special character and needs to be escaped when used as part of a String, e.g., "\". Here is an example of a string comparison using the '\' character:

if (invName.substring(j,k).equals("\\")) {...}

You can also perform direct character comparisons using logic similar to the following:

if (invName.charAt(j) == '\\') {...}

if (!$("#element").attr('my_attr')){
  //return false
  //attribute doesn't exists
}

If you installed php with homebrew, then check if your apache2.conf file is using homebrew version of php5.so file.

$("form").validate().settings.ignore = "*";

Or

$("form").validate().cancelSubmit = true;

But without success in a custom required validator. For call a submit dynamically, i have created a fake hidden submit button with this code:

var btn = form.children('input.cancel.fakeSubmitFormButton');
if (btn.length === 0) {
    btn = $('<input name="FakeCancelSubmitButton" class="cancel fakeSubmitFormButton hide" type="submit" formnovalidate value="FakeCancelSubmitButton" />');
    form.append(btn);
}
btn.click();

Now skip the validation correctly :)

Simple socket server app example

I've already posted a client example at: https://stackoverflow.com/a/35971718/895245 , so here goes a server example.

This example app runs a server that returns a ROT-1 cypher of the input.

You would then need to add an Exit button + some sleep delays, but this should get you started.

To play with it:

• install the app
• get your phone and PC on a LAN
• find your phone's IP with https://android.stackexchange.com/a/130468/126934
• run netcat $PHONE_IP 12345
• type some lines

Android sockets are the same as Java's, except we have to deal with some permission issues.

Assuming that you are using a spfile to start the database

alter system set open_cursors = 1000 scope=both;

If you are using a pfile instead, you can change the setting for the running instance

alter system set open_cursors = 1000 

You would also then need to edit the parameter file to specify the new open_cursors setting. It would generally be a good idea to restart the database shortly thereafter to make sure that the parameter file change works as expected (it's highly annoying to discover months later the next time that you reboot the database that some parameter file change than no one remembers wasn't done correctly).

I'm also hoping that you are certain that you actually need more than 300 open cursors per session. A large fraction of the time, people that are adjusting this setting actually have a cursor leak and they are simply trying to paper over the bug rather than addressing the root cause.

hashCode() is used for bucketing in Hash implementations like HashMap, HashTable, HashSet, etc.

The value received from hashCode() is used as the bucket number for storing elements of the set/map. This bucket number is the address of the element inside the set/map.

When you do contains() it will take the hash code of the element, then look for the bucket where hash code points to. If more than 1 element is found in the same bucket (multiple objects can have the same hash code), then it uses the equals() method to evaluate if the objects are equal, and then decide if contains() is true or false, or decide if element could be added in the set or not.

boom.

I received this error in my code because I'd not run JSON.parse(result).

So my result was a string instead of an array of objects.

i.e. I got:

"[{},{}]" 

instead of:

[{},{}]

import { Storage } from '@ionic/storage';
...
private static readonly SERVER = 'server';
...
getStorage(): Promise {
  return this.storage.get(LoginService.SERVER);
}
...
this.getStorage()
  .then((value) => {
     let servers: Server[] = JSON.parse(value) as Server[];
                   }
  );

The mutable keyword is a way to pierce the const veil you drape over your objects. If you have a const reference or pointer to an object, you cannot modify that object in any way except when and how it is marked mutable.

With your const reference or pointer you are constrained to:

• only read access for any visible data members
• permission to call only methods that are marked as const.

The mutable exception makes it so you can now write or set data members that are marked mutable. That's the only externally visible difference.

Internally those const methods that are visible to you can also write to data members that are marked mutable. Essentially the const veil is pierced comprehensively. It is completely up to the API designer to ensure that mutable doesn't destroy the const concept and is only used in useful special cases. The mutable keyword helps because it clearly marks data members that are subject to these special cases.

In practice you can use const obsessively throughout your codebase (you essentially want to "infect" your codebase with the const "disease"). In this world pointers and references are const with very few exceptions, yielding code that is easier to reason about and understand. For a interesting digression look up "referential transparency".

Without the mutable keyword you will eventually be forced to use const_cast to handle the various useful special cases it allows (caching, ref counting, debug data, etc.). Unfortunately const_cast is significantly more destructive than mutable because it forces the API client to destroy the const protection of the objects (s)he is using. Additionally it causes widespread const destruction: const_casting a const pointer or reference allows unfettered write and method calling access to visible members. In contrast mutable requires the API designer to exercise fine grained control over the const exceptions, and usually these exceptions are hidden in const methods operating on private data.

(N.B. I refer to to data and method visibility a few times. I'm talking about members marked as public vs. private or protected which is a totally different type of object protection discussed here.)

I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.

Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes

To view localhost website from mobile device you have to follow thoses steps :

• In your computer, you have to retrieve your IP address (Run > cmd > ipconfig)
• If your localhost use a specific port (like localhost:12345 ), you have to open the port on your computer (Control Panel > System and Security > Firewall > Advanced settings and add Inbound rule)
• Finally, you can access to your website from mobile device by navigate to : http://192.168.X.X:12345/

Hope it helps

You are not passing the variable correctly. One fast solution is to make a global variable like this:

var global_json_data;
$(document).ready(function() {
    var json_source = "https://spreadsheets.google.com/feeds/list/0ApL1zT2P00q5dG1wOUMzSlNVV3VRV2pwQ2Fnbmt3M0E/od7/public/basic?alt=json";
    var string_data ="";
    var json_data = $.ajax({
        dataType: 'json', // Return JSON
        url: json_source,
        success: function(data){
            var data_obj = [];
            for (i=0; i<data.feed.entry.length; i++){
                var el = {'key': data.feed.entry[i].title['$t'], 'value': '<p><a href="'+data.feed.entry[i].content['$t']+'>'+data.feed.entry[i].title['$t']+'</a></p>'};
                data_obj.push(el)};

            console.log("data grabbed");  
            global_json_data =   data_obj;

            return data_obj;


        },      

        error: function(jqXHR, textStatus, errorThrown){ 
                        $('#results_box').html('<h2>Something went wrong!</h2><p><b>' + textStatus  + '</b> ' + errorThrown  + '</p>');
        }
    }); 

    $(':submit').click(function(event){
        var json_data = global_json_data;
        event.preventDefault();
        console.log(json_data.length);

        //function
        if ($('#place').val() !=''){
            var copy_string = $('#place').val();
            var converted_string = copy_string;
            for (i=0; i<json_data.length; i++){
                //console_log(data.feed.entry[i].title['$t']);
                converted_string = converted_string.replace(json_data.feed.entry[i].title['$t'], 
                    '<a href="'+json_data.feed.entry[i].content['$t']+'>'+json_data.feed.entry[i].title['$t']+'</a>');
            }  
            $('#results_box').text(converted_string).html();
        }
    });

});//document ready end 

You mention that you will call on each vertical column so that you can perform calculations. I assume that you just want to examine each single variable. This can be done through the following.

df <- read.csv("myRandomFile.csv", header=TRUE)

df$ID

df$GRADES

df$GPA

Might be helpful just to assign the data to a variable.

var3 <- df$GPA

On a Mac, you can do this to copy it to your clipboard (like cmd + c shortcut)
cat ~/Desktop/ded.html | pbcopy
pbcopy < ~/.ssh/id_rsa.pub

and to paste pbpaste > ~Documents/id_rsa.txt

or, use cmd + v shorcut to paste it somewhere else.

~/.ssh is the same path as /Users/macbook-username/.ssh
You can use Print work directory: pwd command on terminal to get the path to your current directory.

Sample DF:

In [79]: df = pd.DataFrame(np.random.randint(5, 15, (10, 3)), columns=list('abc'))

In [80]: df
Out[80]:
    a   b   c
0   6  11  11
1  14   7   8
2  13   5  11
3  13   7  11
4  13   5   9
5   5  11   9
6   9   8   6
7   5  11  10
8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

Until all modern browsers will start support css-selector :focus-visible,
the simplest and possibly best way to save accessibility is to remove this tricky focus only for mouse users and to save it for keyboard users:

1.Use this tiny polyfill (about 10kb): https://github.com/WICG/focus-visible
2.Add next code somewhere in your css:

.js-focus-visible :focus:not(.focus-visible) {
  outline: none;
}

Browser-support of css4-selector :focus-visible right now very weak:
https://caniuse.com/#search=focus-visible

I was able to overcome this by using the "vh" metric with max-height on the .modal-body element. 70vh looked about right for my uses. Then set the overflow-y to auto so it only scrolls when needed.

.modal-body {
   overflow-y: auto;
   max-height: 70vh;
}

You can use the getimagesize function like this:

list($width, $height) = getimagesize('path to image');
echo "width: " . $width . "<br />";
echo "height: " .  $height;

I use that construction whenever I don't want to add complexity to the problem. It's just a list, no need to say what kind of List it is, as it doesn't matter to the problem. I often use Collection for most of my solutions, as, in the end, most of the times, for the rest of the software, what really matters is the content it holds, and I don't want to add new objects to the Collection.

Futhermore, you use that construction when you think that you may want to change the implemenation of list you are using. Let's say you were using the construction with an ArrayList, and your problem wasn't thread safe. Now, you want to make it thread safe, and for part of your solution, you change to use a Vector, for example. As for the other uses of that list won't matter if it's a AraryList or a Vector, just a List, no new modifications will be needed.

I've answered my own question. Call apply_filter and there you go.

<?php 
$id=47; 
$post = get_post($id); 
$content = apply_filters('the_content', $post->post_content); 
echo $content;  
?>

Addition to @MarkR answer - one thing to note would be that many PHP frameworks with ORMs would not recognize or use advanced DB setup (foreign keys, cascading delete, unique constraints), and this may result in unexpected behaviour.

For example if you delete a record using ORM, and your DELETE CASCADE will delete records in related tables, ORM's attempt to delete these related records (often automatic) will result in error.

Function taken from http://www.php.net/manual/en/function.max.php

function max_key($array) {
    foreach ($array as $key => $val) {
        if ($val == max($array)) return $key; 
    }
}

$arr = array (
    '11' => 14,
    '10' => 9,
    '12' => 7,
    '13' => 7,
    '14' => 4,
    '15' => 6
);

die(var_dump(max_key($arr)));

Works like a charm

Create a bi-directional relationship, like this:

@Entity
public class Parent implements Serializable {

    @Id
    @GeneratedValue
    private long id;

    @OneToMany(mappedBy = "parent", cascade = CascadeType.REMOVE)
    private Set<Child> children;
}

Bit of a tweak to Jocker's response (I would post as a comment, but I don't have enough karma yet):

SELECT TABLE_NAME, ENGINE
  FROM information_schema.TABLES
 WHERE TABLE_SCHEMA = 'database' AND ENGINE IS NOT NULL;

This excludes MySQL views from the list, which don't have an engine.

Before the closing body tag add this (reference to jQuery library). Other hosted libraries can be found here

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

And this

  //paste your code here
</script>

It should look something like this

Here you can find a nice tutorial of how you can create and consume a SOAP service through WSDL. Long story short you need to call wsimport tool from command line (you can find it in your jdk) with parameters like -s (source for .java files) -d (destination for .class files) and the wsdl link.

$ wsimport -s "C:\workspace\soap\src\main\java\com\test\soap\ws" -d "C:\workspace\soap\target\classes\com\test\soap\ws" http://localhost:8855/soap/test?wsdl

After the stubs are created, you can call the webservices very easy something like:

TestHarnessService harnessService = new TestHarnessService();
ITestApi testApi = harnessService.getBasicHttpBindingITestApi();
testApi.resetLogMemoryTarget();

1.If I have something like Foo o = new Foo(); inside the method, does that mean that each time the timer ticks, I'm creating a new object and a new reference to that object?

Yes.

2.If I have string foo = null and then I just put something temporal in foo, is it the same as above?

If you are asking if the behavior is the same then yes.

3.Does the garbage collector ever delete the object and the reference or objects are continually created and stay in memory?

The memory used by those objects is most certainly collected after the references are deemed to be unused.

4.If I just declare Foo o; and not point it to any instance, isn't that disposed when the method ends?

No, since no object was created then there is no object to collect (dispose is not the right word).

5.If I want to ensure that everything is deleted, what is the best way of doing it

If the object's class implements IDisposable then you certainly want to greedily call Dispose as soon as possible. The using keyword makes this easier because it calls Dispose automatically in an exception-safe way.

Other than that there really is nothing else you need to do except to stop using the object. If the reference is a local variable then when it goes out of scope it will be eligible for collection.¹ If it is a class level variable then you may need to assign null to it to make it eligible before the containing class is eligible.

¹This is technically incorrect (or at least a little misleading). An object can be eligible for collection long before it goes out of scope. The CLR is optimized to collect memory when it detects that a reference is no longer used. In extreme cases the CLR can collect an object even while one of its methods is still executing!

Update:

Here is an example that demonstrates that the GC will collect objects even though they may still be in-scope. You have to compile a Release build and run this outside of the debugger.

static void Main(string[] args)
{
    Console.WriteLine("Before allocation");
    var bo = new BigObject();
    Console.WriteLine("After allocation");
    bo.SomeMethod();
    Console.ReadLine();
    // The object is technically in-scope here which means it must still be rooted.
}

private class BigObject
{
    private byte[] LotsOfMemory = new byte[Int32.MaxValue / 4];

    public BigObject()
    {
        Console.WriteLine("BigObject()");
    }

    ~BigObject()
    {
        Console.WriteLine("~BigObject()");
    }

    public void SomeMethod()
    {
        Console.WriteLine("Begin SomeMethod");
        GC.Collect();
        GC.WaitForPendingFinalizers();
        Console.WriteLine("End SomeMethod");
    }
}

On my machine the finalizer is run while SomeMethod is still executing!

This worked for me:

Remove-Item $folderPath -Force  -Recurse -ErrorAction SilentlyContinue

Thus the folder is removed with all files in there and it is not producing error if folder path doesn't exists.

Based on this forum post: https://groups.google.com/forum/#!topic/ggplot2/mK9DR3dKIBU

Sounds like the easiest thing to do is to add a line break (\n) before your x axis, and after your y axis labels. Seems a lot easier (although dumber) than the solutions posted above.

ggplot(mpg, aes(cty, hwy)) + 
    geom_point() + 
    xlab("\nYour_x_Label") + ylab("Your_y_Label\n")

Hope that helps!

• Approach 1 - transform translateX/translateY:

  Example Here / Full Screen Example

  In supported browsers (most of them), you can use top: 50%/left: 50% in combination with translateX(-50%) translateY(-50%) to dynamically vertically/horizontally center the element.

.container {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 50%;_x000D_
    -moz-transform: translateX(-50%) translateY(-50%);_x000D_
    -webkit-transform: translateX(-50%) translateY(-50%);_x000D_
    transform: translateX(-50%) translateY(-50%);_x000D_
}

<div class="container">_x000D_
    <span>I'm vertically/horizontally centered!</span>_x000D_
</div>

• Approach 2 - Flexbox method:

  Example Here / Full Screen Example

  In supported browsers, set the display of the targeted element to flex and use align-items: center for vertical centering and justify-content: center for horizontal centering. Just don't forget to add vendor prefixes for additional browser support (see example).

html, body, .container {_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.container {_x000D_
    display: -webkit-flexbox;_x000D_
    display: -ms-flexbox;_x000D_
    display: -webkit-flex;_x000D_
    display: flex;_x000D_
    -webkit-flex-align: center;_x000D_
    -ms-flex-align: center;_x000D_
    -webkit-align-items: center;_x000D_
    align-items: center;_x000D_
    justify-content: center;_x000D_
}

<div class="container"> _x000D_
  <span>I'm vertically/horizontally centered!</span>_x000D_
</div>

• Approach 3 - table-cell/vertical-align: middle:

  Example Here / Full Screen Example

  In some cases, you will need to ensure that the html/body element's height is set to 100%.

  For vertical alignment, set the parent element's width/height to 100% and add display: table. Then for the child element, change the display to table-cell and add vertical-align: middle.

  For horizontal centering, you could either add text-align: center to center the text and any other inline children elements. Alternatively, you could use margin: 0 auto, assuming the element is block level.

html, body {_x000D_
    height: 100%;_x000D_
}_x000D_
.parent {_x000D_
    width: 100%;_x000D_
    height: 100%;_x000D_
    display: table;_x000D_
    text-align: center;_x000D_
}_x000D_
.parent > .child {_x000D_
    display: table-cell;_x000D_
    vertical-align: middle;_x000D_
}

<section class="parent">_x000D_
    <div class="child">I'm vertically/horizontally centered!</div>_x000D_
</section>

• Approach 4 - Absolutely positioned 50% from the top with displacement:

  Example Here / Full Screen Example

  This approach assumes that the text has a known height - in this instance, 18px. Just absolutely position the element 50% from the top, relative to the parent element. Use a negative margin-top value that is half of the element's known height, in this case - -9px.

html, body, .container {_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.container {_x000D_
    position: relative;_x000D_
    text-align: center;_x000D_
}_x000D_
_x000D_
.container > p {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 0;_x000D_
    right: 0;_x000D_
    margin-top: -9px;_x000D_
}

<div class="container">_x000D_
    <p>I'm vertically/horizontally centered!</p>_x000D_
</div>

• Approach 5 - The line-height method (Least flexible - not suggested):

  Example Here

  In some cases, the parent element will have a fixed height. For vertical centering, all you have to do is set a line-height value on the child element equal to the fixed height of the parent element.

  Though this solution will work in some cases, it's worth noting that it won't work when there are multiple lines of text - like this.

.parent {_x000D_
    height: 200px;_x000D_
    width: 400px;_x000D_
    background: lightgray;_x000D_
    text-align: center;_x000D_
}_x000D_
_x000D_
.parent > .child {_x000D_
    line-height: 200px;_x000D_
}

<div class="parent">_x000D_
    <span class="child">I'm vertically/horizontally centered!</span>_x000D_
</div>

I was facing this issue for long time. Finally it was issue of ssh-add. Git ssh credentials were not taken into consideration.

Did you try the duct tape solution?

Try to determine when errors occur and fix them with short if statements, it's not pretty but for some problems it is the only solution and this is one of them.

 if( (n * 0.1) < 100.0 ) { return n * 0.1 - 0.000000000000001 ;}
                    else { return n * 0.1 + 0.000000000000001 ;}    

I had the same problem in a scientific simulation project in c#, and I can tell you that if you ignore the butterfly effect it's gonna turn to a big fat dragon and bite you in the a**

f ? O(g) says, essentially

For at least one choice of a constant k > 0, you can find a constant a such that the inequality 0 <= f(x) <= k g(x) holds for all x > a.

Note that O(g) is the set of all functions for which this condition holds.

f ? o(g) says, essentially

For every choice of a constant k > 0, you can find a constant a such that the inequality 0 <= f(x) < k g(x) holds for all x > a.

Once again, note that o(g) is a set.

In Big-O, it is only necessary that you find a particular multiplier k for which the inequality holds beyond some minimum x.

In Little-o, it must be that there is a minimum x after which the inequality holds no matter how small you make k, as long as it is not negative or zero.

These both describe upper bounds, although somewhat counter-intuitively, Little-o is the stronger statement. There is a much larger gap between the growth rates of f and g if f ? o(g) than if f ? O(g).

One illustration of the disparity is this: f ? O(f) is true, but f ? o(f) is false. Therefore, Big-O can be read as "f ? O(g) means that f's asymptotic growth is no faster than g's", whereas "f ? o(g) means that f's asymptotic growth is strictly slower than g's". It's like <= versus <.

More specifically, if the value of g(x) is a constant multiple of the value of f(x), then f ? O(g) is true. This is why you can drop constants when working with big-O notation.

However, for f ? o(g) to be true, then g must include a higher power of x in its formula, and so the relative separation between f(x) and g(x) must actually get larger as x gets larger.

To use purely math examples (rather than referring to algorithms):

The following are true for Big-O, but would not be true if you used little-o:

• x² ? O(x²)
• x² ? O(x² + x)
• x² ? O(200 * x²)

The following are true for little-o:

• x² ? o(x³)
• x² ? o(x!)
• ln(x) ? o(x)

Note that if f ? o(g), this implies f ? O(g). e.g. x² ? o(x³) so it is also true that x² ? O(x³), (again, think of O as <= and o as <)

I think the following offers a slightly different approach... compare fn_fast_fail() with fn_slow_fail()... though the latter doesn't fail as such... you can check if one or both of a and b is an instance of Error and throw that Error if you want it to reach the catch block (e.g. if (b instanceof Error) { throw b; }) . See the jsfiddle.

var p1 = new Promise((resolve, reject) => { 
    setTimeout(() => resolve('p1_delayed_resolvement'), 2000); 
}); 

var p2 = new Promise((resolve, reject) => {
    reject(new Error('p2_immediate_rejection'));
});

var fn_fast_fail = async function () {
    try {
        var [a, b] = await Promise.all([p1, p2]);
        console.log(a); // "p1_delayed_resolvement"
        console.log(b); // "Error: p2_immediate_rejection"
    } catch (err) {
        console.log('ERROR:', err);
    }
}

var fn_slow_fail = async function () {
    try {
        var [a, b] = await Promise.all([
            p1.catch(error => { return error }),
            p2.catch(error => { return error })
        ]);
        console.log(a); // "p1_delayed_resolvement"
        console.log(b); // "Error: p2_immediate_rejection"
    } catch (err) {
        // we don't reach here unless you throw the error from the `try` block
        console.log('ERROR:', err);
    }
}

fn_fast_fail(); // fails immediately
fn_slow_fail(); // waits for delayed promise to resolve

By this method, you can resume your program just by pressing any specified key you've specified that:

import keyboard
while True:
    key = keyboard.read_key()
    if key == 'space':  # You can put any key you like instead of 'space'
        break

The same method, but in another way:

import keyboard
while True:
    if keyboard.is_pressed('space'):  # The same. you can put any key you like instead of 'space'
        break

Note: you can install the keyboard module simply by writing this in you shell or cmd:

pip install keyboard

You could just add a few COUNTIF statements together:

=COUNTIF(A1:A196,"yes")+COUNTIF(A1:A196,"no")+COUNTIF(J1:J196,"agree")

This will give you the result you need.

EDIT

Sorry, misread the question. Nicholas is right that the above will double count. I wasn't thinking of the AND condition the right way. Here's an alternative that should give you the correct results, which you were pretty close to in the first place:

=SUM(COUNTIFS(A1:A196,{"yes","no"},J1:J196,"agree"))

I voted for Vinh's answer to get the value.

If you need to find the corresponding label, you can use this code:

$('#ClientID' + ' input:checked').parent().find('label').text()

The easiest way I've found to do this is to write in markdown right from the start of the line. Press Ctrl+D (shortcut for opening the markup input dialog) and type markdown. The normal wiki editor doesn't seem to be very good for precise formatting. It doesn't seem to know much about character styles and only knows paragraph styles.

If you don't find Stencils you can locate them in your install location. C:\Program Files\Microsoft Office\Office15\Visio Content\1033 for UML Sequcen Stencies you can open

If you want to pass Method as parameter, use:

using System;

public void Method1()
{
    CallingMethod(CalledMethod);
}

public void CallingMethod(Action method)
{
    method();   // This will call the method that has been passed as parameter
}

public void CalledMethod()
{
    Console.WriteLine("This method is called by passing parameter");
}

Please note that the code above was tested on Code::Blocks 12.11 and Visual Studio 2012
on Windows 7.

For forcing your programme stop or wait, you have several options :

• sleep(unsigned int)

The value has to be a positive integer in millisecond. That means that if you want your programme wait for 2 seconds, enter 2000.

Here's an example :

#include <iostream>     //for using cout
#include <stdlib.h>     //for using the function sleep

using namespace std;    //for using cout

int main(void)         
{
   cout << "test" << endl;
   sleep(5000);         //make the programme waiting for 5 seconds
   cout << "test" << endl;
   sleep(2000);         // wait for 2 seconds before closing

   return 0;
}

If you wait too long, that probably means the parameter is in seconds. So change it to this:

sleep(5);

For those who get error message or problem using sleep try to replace it by _sleep or Sleep especially on Code::Bloks.
And if you still getting problems, try to add of one this library on the beginning of the code.

#include <stdio.h>
#include <time.h>
#include <unistd.h>
#include <dos.h>
#include <windows.h>

• system("PAUSE")

A simple "Hello world" programme on windows console application would probably close before you can see anything. That the case where you can use system("Pause").

#include <iostream>    

using namespace std;   

int main(void)         
{
    cout << "Hello world!" << endl;

    system("PAUSE");

    return 0;
}

If you get the message "error: 'system' was not declared in this scope" just add the following line at the biggining of the code :

#include <cstdlib>

• cin.ignore()

The same result can be reached by using cin.ignore() :

#include <iostream>     

using namespace std;    

int main(void)         
{
    cout << "Hello world!" << endl;

    cin.ignore();

    return 0;
}

• cin.get()

example :

#include <iostream>     

using namespace std;    

int main(void)         
{
    cout << "Hello world!" << endl;

    cin.get();

    return 0;
}

• getch()

Just don't forget to add the library conio.h :

#include <iostream>     
#include <conio.h>    //for using the function getch()

using namespace std;    

int main(void)
{

    cout << "Hello world!" << endl;

    getch();

    return 0;
}

You can have message telling you to use _getch() insted of getch

If you need specific columns printed with arbitrary delimeter:

awk '{print $3 "  " $4}'

col#3 col#4

awk '{print $3 "anything" $4}'

col#3anythingcol#4

So if you have whitespace in a column it will be two columns, but you can connect it with any delimiter or without it.

Recently had this problem but with unkown number of promises.Solved using jQuery.map().

function methodThatChainsPromises(args) {

    //var args = [
    //    'myArg1',
    //    'myArg2',
    //    'myArg3',
    //];

    var deferred = $q.defer();
    var chain = args.map(methodThatTakeArgAndReturnsPromise);

    $q.all(chain)
    .then(function () {
        $log.debug('All promises have been resolved.');
        deferred.resolve();
    })
    .catch(function () {
        $log.debug('One or more promises failed.');
        deferred.reject();
    });

    return deferred.promise;
}

No, unfortunately this will not be possible because ConverterParameter is not a DependencyProperty so you won't be able to use bindings

But perhaps you could cheat and use a MultiBinding with IMultiValueConverter to pass in the 2 Tag properties.

At FirstScreen.java

    Intent intent = new Intent(FirstScreen.this, SecondScreen.class);
    String keyIdentifier = null;
    intent.putExtra(strName, keyIdentifier);

At SecondScreen.java

    String keyIdentifier;
    if (savedInstanceState != null)
        keyIdentifier= (String) savedInstanceState.getSerializable(strName);
    else
        keyIdentifier = getIntent().getExtras().getString(strName);

You've many options to do that, but the best one is using the AWS CLI.

Here's a walk-through:

1. Download and install AWS CLI in your machine:

   • Install the AWS CLI using the MSI Installer (Windows).
   • Install the AWS CLI using the Bundled Installer for Linux, OS X, or Unix.

2. Configure AWS CLI:

   

   Make sure you input valid access and secret keys, which you received when you created the account.

3. Sync the S3 bucket using:

   aws s3 sync s3://yourbucket /local/path
   

   In the above command, replace the following fields:

   • yourbucket >> your S3 bucket that you want to download.
   • /local/path >> path in your local system where you want to download all the files.

Web.xml is called as deployment descriptor file and its is is an XML file that contains information on the configuration of the web application, including the configuration of servlets.

really this belongs as a comment to Nathan's answer, but I'm not allowed to do that yet...
I wanted to maintain the aspect ratio, even if there is too much stuff to fit in the box. His example expands the height, changing the aspect ratio. I found adding

overflow: hidden;
overflow-x: auto;
overflow-y: auto;

to the .element helped. See http://jsfiddle.net/B8FU8/3111/

Invoking dev.off() to make RStudio open up a new graphics device with default settings worked for me. HTH.

I find using str.format much more elegant:

>>> '{0: <5}'.format('s')
's    '
>>> '{0: <5}'.format('ss')
'ss   '
>>> '{0: <5}'.format('sss')
'sss  '
>>> '{0: <5}'.format('ssss')
'ssss '
>>> '{0: <5}'.format('sssss')
'sssss'

If you want to align the string to the right use > instead of <:

>>> '{0: >5}'.format('ss')
'   ss'

Edit 1: As mentioned in the comments: the 0 in '{0: <5}' indicates the argument’s index passed to str.format().

Edit 2: In python3 one could use also f-strings:

sub_str='s'
for i in range(1,6):
    s = sub_str*i
    print(f'{s:>5}')
    
'    s'
'   ss'
'  sss'
' ssss'
'sssss'

or:

for i in range(1,5):
    s = sub_str*i
    print(f'{s:<5}')
's    '
'ss   '
'sss  '
'ssss '
'sssss'

of note, in some places above, ' ' (single quotation marks) were added to emphasize the width of the printed strings.

You can rename your Conda env by just renaming the env folder. Here is the proof:

You can find your Conda env folder inside of C:\ProgramData\Anaconda3\envs or you can enter conda env list to see the list of conda envs and its location.

Short answer: You can't.

CSS does not have techniques which affect the rendering of fonts in the browser; only the system can do that.

Obviously, text sharpness can easily be achieved with pixel-dense screens, but if you're using a normal PC that's gonna be hard to achieve.

There are some newer fonts that are smooth but at the sacrifice of it appearing somewhat blurry (look at most of Adobe's fonts, for example). You can also find some smooth-but-blurry-by-design fonts at Google Fonts, however.

There are some new CSS3 techniques for font rendering and text effects though the consistency, performance, and reliability of these techniques vary so largely to the point where you generally shouldn't rely on them too much.

CODE

$('#montant-total-prevu').on("change", function() {

var taille = $('#montant-total-prevu').val().length;

    if (taille > 9) {

//TODO

}

});

If you are using the Support Library provided DrawerLayout as suggested in the Creating a navigation drawer training, you can use the newly added android.support.v7.app.ActionBarDrawerToggle (note: different from the now deprecated android.support.v4.app.ActionBarDrawerToggle):

shows a Hamburger icon when drawer is closed and an arrow when drawer is open. It animates between these two states as the drawer opens.

While the training hasn't been updated to take the deprecation/new class into account, you should be able to use it almost exactly the same code - the only difference in implementing it is the constructor.

There might be a problem with your DNS servers of the ISP. A computer by default uses the ISP's DNS servers. You can manually configure your DNS servers. It is free and usually better than your ISP.

1. Go to Control Panel ? Network and Internet ? Network and Sharing Centre
2. Click on Change Adapter settings.
3. Right click on your connection icon (Wireless Network Connection or Local Area Connection) and select properties.
4. Select Internet protocol version 4.
5. Click on "Use the following DNS server address" and type either of the two DNS given below.

Google Public DNS

Preferred DNS server : 8.8.8.8
Alternate DNS server : 8.8.4.4

OpenDNS

Preferred DNS server : 208.67.222.222
Alternate DNS server : 208.67.220.220

Even if the question is marked answered, I would like to add some points to it.

Set the DropDownStyle property of the combobox to DropDownList works for sure.

BUT what if the drop down list is longer, the user will have to scroll it to the desired item as he has no access to keyboard.

 Private Sub cbostate_Validating(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles cbostate.Validating
    If cbostate.SelectedValue Is Nothing AndAlso cbostate.Text <> String.Empty Then
        e.Cancel = True
        MsgBox("Invalid State")
    End If
End Sub

I did it like this. I wanted to restrict the user entering 'random values' instead of 'state' but keeping he should be able to type and search states.

This validating event occurs when the control loses focus. So if user enters wrong value in combobox, It will not allow user to do anything on the form, perhaps it will not even allow to change the focus from the combobox

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

To make cell width exactly same as the longest word of the text, just set width of the cell to 1px

i.e.

td {
  width: 1px;
}

This is experimental and i came to know about this while doing trial and error
