I just had this problem myself because I was in the wrong folder. I was nested 1 level in, so there were no git files to be found.

When I execute cd .. to the correct directory, I was able to commit, as expected.

You can avoid the error by setting default device before launching application. Launch the AVD before starting the app.

Using the below line

MySQL Doc.

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

Module MyHelpers
    <Extension()>
    Public Function UnEscape(ByVal aString As String) As String

       Return Regex.Unescape(aString)

    End Function
End Module

Usage:

console.writeline("Ciao!\n".unEscape)

process.terminate() doesn't work when using shell=True. This answer will help you.

Could be because of restoring SQL Server 2012 version backup file into SQL Server 2008 R2 or even less.

Quoting is an issue if you're running awk from the command line. You'll sometimes need to use \, e.g. to quote ", but most of the time you'll use ^:

w:\srv>dir | grep ".txt" | awk "{ printf(\"echo %s@%s ^> %s.tstamp^\n\", $1, $2, $4); }"
echo 2014-09-07@22:21 > requirements-dev.txt.tstamp
echo 2014-11-28@18:14 > syncspec.txt.tstamp

I believe you are looking for DateTime.Today. The documentation states:

An object that is set to today's date, with the time component set to 00:00:00.

http://msdn.microsoft.com/en-us/library/system.datetime.today.aspx

Your code would be

DateTime _Begin = DateTime.Today;

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=yourpassword
MAIL_ENCRYPTION=tls
MAIL_FROM_NAME='Name'

Here is my solution:

<!-- jquery smooth scroll to id's -->   
<script>
$(function() {
  $('a[href*=\\#]:not([href=\\#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 500);
        return false;
      }
    }
  });
});
</script>

With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.

I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)

For clarifications, let me know. Hope it helps!

If you only want to sort only on the 5th field then use -k5,5.

Also, use the -t command line switch to specify the delimiter to tab. Try this:

sort  -k5,5 -r -n -t \t filename

or if the above doesn't work (with the tab) this:

sort  -k5,5 -r -n -t $'\t' filename

The man page for sort states:

-t, --field-separator=SEP use SEP instead of non-blank to blank transition

Finally, this SO question Unix Sort with Tab Delimiter might be helpful.

Get a handle to the root ThreadGroup, like this:

ThreadGroup rootGroup = Thread.currentThread().getThreadGroup();
ThreadGroup parentGroup;
while ((parentGroup = rootGroup.getParent()) != null) {
    rootGroup = parentGroup;
}

Now, call the enumerate() function on the root group repeatedly. The second argument lets you get all threads, recursively:

Thread[] threads = new Thread[rootGroup.activeCount()];
while (rootGroup.enumerate(threads, true ) == threads.length) {
    threads = new Thread[threads.length * 2];
}

Note how we call enumerate() repeatedly until the array is large enough to contain all entries.

Use #define OSsymbol and #ifdef OSsymbol where OSsymbol is a #define'able symbol identifying your target OS.

Typically you would include a central header file defining the selected OS symbol and use OS-specific include and library directories to compile and build.

You did not specify your development environment, but I'm pretty sure your compiler provides global defines for common platforms and OSes.

Simples

function time($block) {

then can use as

time { .\some_command }

You may want to tweak the output

Usually, IllegalStateException is used to indicate that "a method has been invoked at an illegal or inappropriate time." However, this doesn't look like a particularly typical use of it.

The code you've linked to shows that it can be thrown within that code at line 259 - but only after dumping a SQLException to standard output.

We can't tell what's wrong just from that exception - and better code would have used the original SQLException as a "cause" exception (or just let the original exception propagate up the stack) - but you should be able to see more details on standard output. Look at that information, and you should be able to see what caused the exception, and fix it.

None of the solutions posted here would work for me, this was my eventual solution to the problem.

// In Server Side code
protected void Page_Load(object sender, EventArgs e)
{
    Page.GetPostBackEventReference(hiddenButton);
}

// Javascript
function SetSaved() {
    __doPostBack("<%= hiddenButton.UniqueID %>", "OnClick");
}

// ASP
 <asp:Button ID="hiddenButton" runat="server" OnClick="btnSaveGroup_Click" Visible="false"/>

Exception class has two constructors

• public Exception() -- This constructs an Exception without any additional information.Nature of the exception is typically inferred from the class name.
• public Exception(String s) -- Constructs an exception with specified error message.A detail message is a String that describes the error condition for this particular exception.

When you read from a binary file, a data type called bytes is used. This is a bit like list or tuple, except it can only store integers from 0 to 255.

Try:

file_size = fin.read(4)
file_size0 = file_size[0]
file_size1 = file_size[1]
file_size2 = file_size[2]
file_size3 = file_size[3]

Or:

file_size = list(fin.read(4))

Instead of:

file_size = int(fin.read(4))

You may use clone() which works well if your object has immutable objects and/or primitives, but it may be a little problematic when you don't have these ( such as collections ) for which you may need to perform a deep clone.

User userCopy = (User) user.clone();//make a copy

for(...) {
    user.age = 1;
    user.id = -1;

    UserDao.update(user)
    user = userCopy; 
}

It seems like you just want to preserve the attributes: age and id which are of type int so, why don't you give it a try and see if it works.

For more complex scenarios you could create a "copy" method:

publc class User { 
    public static User copy( User other ) {
         User newUser = new User();
         newUser.age = other.age;
         newUser.id = other.id;
         //... etc. 
         return newUser;
    }
}

It should take you about 10 minutes.

And then you can use that instead:

     User userCopy = User.copy( user ); //make a copy
     // etc.

As stated in other answers, the simplest method is to uniquely identify the root element (by ID or class name) and use the direct descendent selector.

$('ul.topMenu > li > a')

However, I came across this question in search of a solution which would work on unnamed elements at varying depths of the DOM.

This can be achieved by checking each element, and ensuring it does not have a parent in the list of matched elements. Here is my solution, wrapped in a jQuery selector 'topmost'.

jQuery.extend(jQuery.expr[':'], {
  topmost: function (e, index, match, array) {
    for (var i = 0; i < array.length; i++) {
      if (array[i] !== false && $(e).parents().index(array[i]) >= 0) {
        return false;
      }
    }
    return true;
  }
});

Utilizing this, the solution to the original post is:

$('ul:topmost > li > a')

// Or, more simply:
$('li:topmost > a')

Complete jsFiddle available here.

Per the JQuery documentation, .get() only takes the url, data (content), dataType, and success callback as its parameters. What you're really looking to do here is modify the jqXHR object before it gets sent. With .ajax(), this is done with the beforeSend() method. But since .get() is a shortcut, it doesn't allow it.

It should be relatively easy to switch your .ajax() calls to .get() calls though. After all, .get() is just a subset of .ajax(), so you can probably use all the default values for .ajax() (except, of course, for beforeSend()).

Edit:

::Looks at Jivings' answer::

Oh yeah, forgot about the cache parameter! While beforeSend() is useful for adding other headers, the built-in cache parameter is far simpler here.

An immutable object is the one you cannot modify after you create it. A typical example are string literals.

A D programming language, which becomes increasingly popular, has a notion of "immutability" through "invariant" keyword. Check this Dr.Dobb's article about it - http://dobbscodetalk.com/index.php?option=com_myblog&show=Invariant-Strings.html&Itemid=29 . It explains the problem perfectly.

Up-to-date solution (October 2014) : ready for fluid layouts

Introduction:

This solution is even simpler than the one provided by Leigh. It is actually based on it.

Here you can notice that the middle element (in our case, with "content__middle" class) does not have any dimensional property specified - no width, nor padding, nor margin related property at all - but only an overflow: auto; (see note 1).

The great advantage is that now you can specify a max-width and a min-width to your left & right elements. Which is fantastic for fluid layouts.. hence responsive layout :-)

note 1: versus Leigh's answer where you need to add the margin-left & margin-right properties to the "content__middle" class.

Code with non-fluid layout:

Here the left & right elements (with classes "content__left" and "content__right") have a fixed width (in pixels): hence called non-fluid layout.

Live Demo on http://jsbin.com/qukocefudusu/1/edit?html,css,output

<style>
    /*
     * [1] & [3] "floats" makes the 2 divs align themselves respectively right & left
     * [2] "overflow: auto;" makes this div take the remaining width

    .content {
        width: 100%;
    }
    .content__left {
        width: 100px;
        float: left; /* [1] */
        background-color: #fcc;
    }
    .content__middle {
        background-color: #cfc;
        overflow: auto; /* [2] */
    }
    .content__right {
        width: 100px;
        float: right; /* [3] */
        background-color: #ccf;
    }

    </div>
</div>

Code with fluid layout:

Here the left & right elements (with classes "content__left" and "content__right") have a variable width (in percentages) but also a minimum and maximum width: hence called fluid layout.

Deleting my .pdb file for the dll solved this issue for me. I'm guessing it has something to do with the fact that the dll was created using ILMerge.

You can use free tool called Advanced SQL Server Dependencies http://advancedsqlserverdependencies.codeplex.com/

It supports all database objects (tables, views, etc.) and can find dependencies across multiple databases (in case of synonyms).

first call the intent

Intent intenta = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intenta, 42);

then call the result

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case 42:
            if (resultCode == Activity.RESULT_OK) {
                Uri sdCardUri = data.getData();
                DocumentFile pickedDir = DocumentFile.fromTreeUri(this, sdCardUri);
                for (DocumentFile file : pickedDir.listFiles()) {
                    String pp = file.getName();
                    if(pp.equals("VLC.apk"))
                        file.delete();
                    String ppdf="";
                }
                File pathFile = new File(String.valueOf(sdCardUri));
                pathFile.delete();
            }
            break;
    }
}

In short,

Selection sort : Select the first element from unsorted array and compare it with remaining unsorted elements. It is similar to Bubble sort, but instead of swapping each smaller elements, keeps the smallest element index updated and swap it at the end of each loop.

Insertion sort : It is opposite to Selection sort where it picks first element from unsorted sub-array and compare it with sorted sub-array and insert the smallest element where found and shift all the sorted elements from its right to the first unsorted element.

Here is a good example on how to do a command if a file does or does not exist:

if exist C:\myprogram\sync\data.handler echo Now Exiting && Exit
if not exist C:\myprogram\html\data.sql Exit

We will take those three files and put it in a temporary place. After deleting the folder, it will restore those three files.

xcopy "test" "C:\temp"
xcopy "test2" "C:\temp"
del C:\myprogram\sync\
xcopy "C:\temp" "test"
xcopy "C:\temp" "test2"
del "c:\temp"

Use the XCOPY command:

xcopy "C:\myprogram\html\data.sql"  /c /d /h /e /i /y  "C:\myprogram\sync\"

I will explain what the /c /d /h /e /i /y means:

  /C           Continues copying even if errors occur.
  /D:m-d-y     Copies files changed on or after the specified date.
               If no date is given, copies only those files whose
               source time is newer than the destination time.
  /H           Copies hidden and system files also.
  /E           Copies directories and subdirectories, including empty ones.
               Same as /S /E. May be used to modify /T.
  /T           Creates directory structure, but does not copy files. Does not
               include empty directories or subdirectories. /T /E includes
  /I           If destination does not exist and copying more than one file,
               assumes that destination must be a directory.
  /Y           Suppresses prompting to confirm you want to overwrite an
               existing destination file.

Call other batch file with option sync.bat myprogram.ini.

I am not sure what you mean by this, but if you just want to open both of these files you just put the path of the file like

Path/sync.bat
Path/myprogram.ini

If it was in the Bash environment it was easy for me, but I do not know how to test if a file or folder exists and if it is a file or folder.

You are using a batch file. You mentioned earlier you have to create a .bat file to use this:

I have to create a .BAT file that does this:

This will work with either an array, an object or a variable and also escapes the special characters that may break your JS :

function debugToConsole($msg) { 
        echo "<script>console.log(".json_encode($msg).")</script>";
}

Edit : Added json_encode to the echo statement. This will prevent your script from breaking if there are quotes in your $msg variable.

1. You can use an interface to provide a click listener. I use this technique with ListViews, too.
2. No divider: Simply add in your row a View with a width of match_parent and a height of 1dp and give it a background color.
3. Simply use a StateList selector for the row background.
4. addHeaderView can be avoided in ListViews, too: simply put the Header outside the View.

So, if efficiency is your concern, then yes, it's a good idea to replace a ListView with a RecyclerView.

Make a Facebook app with these simple steps I have written below:

1. Go to Developer tab and click on it.
2. Then go to Website Option.
3. Enter the app name which you have want.
4. Click on Create Facebook App.
5. After this you have to choose category, you can choose App for Pages.
6. Your AppId and Appkey is created automatically. The AppSecretKey is obfuscated. You can click on the show button to see your AppId and AppSecurityKey.

When calling the function, follow it by return false example:

<input  type="submit" value="Add" onclick="addNewPayment();return false;">

The program will terminate when the execution flow reaches the end of the main function.

To terminate it before then, you can use the exit(int status) function, where status is a value returned to whatever started the program. 0 normally indicates a non-error state

I searched for a the same solution with a variable instead of the String.

Not a barplot solution but using lattice and barchart:

         scales=list(x=list(rot=90,cex=0.8)))

I know it's been a little over two years... but I was looking for a way to do this, and wasn't overly happy with the solution posted (it works fine, but I wanted a little more information as the import happens). When combining all the SQL files in to one, you don't get any sort of progress updates.

So I kept digging for an answer and thought this might be a good place to post what I found for future people looking for the same answer. Here's a command line in Windows that will import multiple SQL files from a folder. You run this from the command line while in the directory where mysql.exe is located.

for /f %f in ('dir /b <dir>\<mask>') do mysql --user=<user> --password=<password> <dbname> < <dir>\%f

With some assumed values (as an example):

for /f %f in ('dir /b c:\sqlbackup\*.sql') do mysql --user=mylogin --password=mypass mydb < c:\sqlbackup\%f

If you had two sets of SQL backups in the folder, you could change the *.sql to something more specific (like mydb_*.sql).

I have used the below commands for removing any proxy set:

    npm config rm proxy

In my case it was the wrong dependecy for CrudRepository. My IDE added also follwing:

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-commons</artifactId>
        <version>1.11.2.RELEASE</version>
    </dependency>

But I just needed:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
        <version>RELEASE</version>
    </dependency>

I removed the first one and everything was fine.

Assuming your shell is Bash, you can set the path with

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

but like Levon said in another answer, as soon as you terminate the shell the changes will be gone. You probably want to set up your PATH in ~/.bash_profile or ~/.bashrc.

Here is the code which I am using in my project and it is working fine:

public function getClient(){
    $client = new Google_Client();
    $client->setApplicationName(APPNAME);       // app name
    $client->setClientId(CLIENTID);             // client id
    $client->setClientSecret(CLIENTSECRET);     // client secret 
    $client->setRedirectUri(REDIRECT_URI);      // redirect uri
    $client->setApprovalPrompt('auto');

    $client->setAccessType('offline');         // generates refresh token

    $token = $_COOKIE['ACCESSTOKEN'];          // fetch from cookie

    // if token is present in cookie
    if($token){
        // use the same token
        $client->setAccessToken($token);
    }

    // this line gets the new token if the cookie token was not present
    // otherwise, the same cookie token
    $token = $client->getAccessToken();

    if($client->isAccessTokenExpired()){  // if token expired
        $refreshToken = json_decode($token)->refresh_token;

        // refresh the token
        $client->refreshToken($refreshToken);
    }

    return $client;
}

If you have a list of lists (tracked_output_sheet in my case), where you want to delete last element from each list, you can use the following code:

interim = []
for x in tracked_output_sheet:interim.append(x[:-1])
tracked_output_sheet= interim

I found this page because I needed to migrate a site with many many bindings to a new server. I used some of the code here to generate the powershell script below to add the bindings to the new server. Sharing in case it is useful to someone else:

Import-Module WebAdministration
$Websites = Get-ChildItem IIS:\Sites
$site = $Websites | Where-object { $_.Name -eq 'site-name-in-iis-here' }

$Binding = $Site.bindings
[string]$BindingInfo = $Binding.Collection
[string[]]$Bindings = $BindingInfo.Split(" ")
$i = 0
$header = ""
Do{
    [string[]]$Bindings2 = $Bindings[($i+1)].Split(":")

    Write-Output ("New-WebBinding -Name `"site-name-in-iis-here`" -IPAddress " + $Bindings2[0] + " -Port " + $Bindings2[1] + " -HostHeader `"" + $Bindings2[2] + "`"")

    $i=$i+2
} while ($i -lt ($bindings.count))

It generates records that look like this:

New-WebBinding -Name "site-name-in-iis-here" -IPAddress "*" -Port 80 -HostHeader www.aaa.com

Bonus:

In speaking of pull/fetch/merge in the previous answers, I would like to share an interesting and productive trick,

git pull --rebase

This above command is the most useful command in my Git life which saved a lot of time.

Before pushing your newly commit to server, try this command and it will automatically synchronise the latest server changes (with a fetch + merge) and will place your commit at the top in the Git log. There isn't any need to worry about manual pull/merge.

Find details in What does "git pull --rebase" do?.

The single most important issue to me is that Maven, when not configured properly, may not produce repeatable builds, due to:

• unreliable remote repositories;
• dependencies on plugins and libraries with either SNAPSHOT versions or no versions.

Contrast this with an ant build which - although verbose and tiresome IMO - works since all jars are checked in locally.

The good part is that the problems are addressable:

• use your own maven repository, which has become dead simple, I'm using Archiva with good results;
• always properly version your dependencies. Maven has started locking down plugin versions in the super-POM starting with 2.0.8 or 2.0.9 and all your dependencies should be on released versions.

If you don't have control of the web server & don't know which variables have been set, upload this php to find out:

I had a similar issue where I was getting the same error message for a user. I feel that by sharing my mistake, I can clear up the issue, answer the question, and prevent others from making the same mistake.
I wanted a user to have access to 4 particular views without having access to their underlying tables (or anything else in the DB for that matter).
Initially I gave them the database role membership of "db_denydatareader" thinking that this would prevent them from selecting anything from any table or view (which it did - as I thought), though I then granted "select" on these 4 views assuming that it would work as I intended - it did not.
The correct way to do it is to simply not grant them the db_datareader role and simply grant "select" on the items which you want the user to be able to access. The results of the above was that the user was able to access absolutely nothing outside these 4 views - the tables which these views area based on are also not available to this user.

If you want to filter rows by a certain number of columns with null values, you may use this:

df.iloc[df[(df.isnull().sum(axis=1) >= qty_of_nuls)].index]

So, here is the example:

Your dataframe:

>>> df = pd.DataFrame([range(4), [0, np.NaN, 0, np.NaN], [0, 0, np.NaN, 0], range(4), [np.NaN, 0, np.NaN, np.NaN]])
>>> df
     0    1    2    3
0  0.0  1.0  2.0  3.0
1  0.0  NaN  0.0  NaN
2  0.0  0.0  NaN  0.0
3  0.0  1.0  2.0  3.0
4  NaN  0.0  NaN  NaN

If you want to select the rows that have two or more columns with null value, you run the following:

>>> qty_of_nuls = 2
>>> df.iloc[df[(df.isnull().sum(axis=1) >=qty_of_nuls)].index]
     0    1    2   3
1  0.0  NaN  0.0 NaN
4  NaN  0.0  NaN NaN

List indexes of -x mean the xth item from the end of the list, so n[-1] means the last item in the list n. Any good Python tutorial should have told you this.

It's an unusual convention that only a few other languages besides Python have adopted, but it is extraordinarily useful; in any other language you'll spend a lot of time writing n[n.length-1] to access the last item of a list.

Do not use primitives in your Entity classes, use instead their respective wrappers. That will fix this problem.

Out of your Entity classes you can use the != null validation for the rest of your code flow.

Semaphore :

Using a counter or flag to control access some shared resources in a concurrent system, implies use of Semaphore.

Example:

1. A counter to allow only 50 Passengers to acquire the 50 seats (Shared resource) of any Theatre/Bus/Train/Fun ride/Classroom. And to allow a new Passenger only if someone vacates a seat.
2. A binary flag indicating the free/occupied status of any Bathroom.
3. Traffic lights are good example of flags. They control flow by regulating passage of vehicles on Roads (Shared resource)

Flags only reveal the current state of Resource, no count or any other information on the waiting or running objects on the resource.

Monitor :

A Monitor synchronizes access to an Object by communicating with threads interested in the object, asking them to acquire access or wait for some condition to become true.

Example:

1. A Father may acts as a monitor for her daughter, allowing her to date only one guy at a time.
2. A school teacher using baton to allow only one child to speak in the class.
3. Lastly a technical one, transactions (via threads) on an Account object synchronized to maintain integrity.

Please check the following file

%SystemRoot%\system32\drivers\etc\host

The line which bind the host name with ip is probably missing a line which bind them togather

127.0.0.1  localhost

If the given line is missing. Add the line in the file

Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.

The simplest way to determine if a variable is an Object or not:

first: Evaluate the type of Object

second: Getting an Array property from an Object must returns undefined (For example length is an Array property which does not work on Object)

so:

if (_object instanceof Object && _object.length === undefined) {
// here you can be sure that you have a curly bracket object :)
}

... And here is the rounding way which doesn't truncate. Hurried to look it up in the Java API Manual:

double d = 1234.56;
long x = Math.round(d); //1235

For me it helped to change the version of buildTools to:

buildToolsVersion "21.0.1"

You will find this setting inside the file app/build.gradle.

If you want to just compare dates,

yourdatetime.date() < datetime.today().date()

Or, obviously,

yourdatetime.date() == datetime.today().date()

If you want to check that they're the same date.

The documentation is usually helpful. It is also usually the first google result for python thing_i_have_a_question_about. Unless your question is about a function/module named "snake".

Basically, the datetime module has three types for storing a point in time:

• date for year, month, day of month
• time for hours, minutes, seconds, microseconds, time zone info
• datetime combines date and time. It has the methods date() and time() to get the corresponding date and time objects, and there's a handy combine function to combine date and time into a datetime.

See this thread by Sun on why they deprecated Thread.stop(). It goes into detail about why this was a bad method and what should be done to safely stop threads in general.

The way they recommend is to use a shared variable as a flag which asks the background thread to stop. This variable can then be set by a different object requesting the thread terminate.

Well, first you need to select the elements with a function like getElementById.

var targetDiv = document.getElementById("foo").getElementsByClassName("bar")[0];

getElementById only returns one node, but getElementsByClassName returns a node list. Since there is only one element with that class name (as far as I can tell), you can just get the first one (that's what the [0] is for—it's just like an array).

Then, you can change the html with .textContent.

targetDiv.textContent = "Goodbye world!";

var targetDiv = document.getElementById("foo").getElementsByClassName("bar")[0];_x000D_
targetDiv.textContent = "Goodbye world!";

<div id="foo">_x000D_
    <div class="bar">_x000D_
        Hello world!_x000D_
    </div>_x000D_
</div>

I found the best fix for this was to give the input a height that matches the label. At least this fixed my problem with inconsistencies in Firefox and IE.

input { height: 18px; margin: 0; float: left; }
label { height: 18px; float: left; }

<li>
  <input id="option1" type="radio" name="opt" />
  <label for="option1">Option 1</label>
</li>

For me the problem was occurring because there was no active Production certificate. I created a new one, and then went to the expired distribution provisioning profile, added the certificate and the provisioning profile got activated.

Eight years later... Microsoft SQL Server vNext Database Engine has finally enhanced Transact-SQL to directly support grouped string concatenation. The Community Technical Preview version 1.0 added the STRING_AGG function and CTP 1.1 added the WITHIN GROUP clause for the STRING_AGG function.

One more alternative

const decToBin = dec => {
  let bin = '';
  let f = false;

  while (!f) {
    bin = bin + (dec % 2);    
    dec = Math.trunc(dec / 2);  

    if (dec === 0 ) f = true;
  }

  return bin.split("").reverse().join("");
}

console.log(decToBin(0));
console.log(decToBin(1));
console.log(decToBin(2));
console.log(decToBin(3));
console.log(decToBin(4));
console.log(decToBin(5));
console.log(decToBin(6));

There is a correct way of uploading a file with its name with Retrofit 2, without any hack:

Define API interface:

@Multipart
@POST("uploadAttachment")
Call<MyResponse> uploadAttachment(@Part MultipartBody.Part filePart); 
                                   // You can add other parameters too

Upload file like this:

File file = // initialize file here

MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));

Call<MyResponse> call = api.uploadAttachment(filePart);

This demonstrates only file uploading, you can also add other parameters in the same method with @Part annotation.

What about display:inline?

<html>
      <img src='#' style='display:inline;'/>
      <p style='display:inline;'> Some text </p>
</html>

To set the use of scientific notation in your entire R session, you can use the scipen option. From the documentation (?options):

‘scipen’: integer.  A penalty to be applied when deciding to print
          numeric values in fixed or exponential notation.  Positive
          values bias towards fixed and negative towards scientific
          notation: fixed notation will be preferred unless it is more
          than ‘scipen’ digits wider.

So in essence this value determines how likely it is that scientific notation will be triggered. So to prevent scientific notation, simply use a large positive value like 999:

options(scipen=999)

To remove duplicates from a single column

 Sub removeDuplicate()
 'removeDuplicate Macro
 Columns("A:A").Select
 ActiveSheet.Range("$A$1:$A$117").RemoveDuplicates Columns:=Array(1), _ 
 Header:=xlNo 
 Range("A1").Select
 End Sub

if you have header then use Header:=xlYes

Increase your range as per your requirement.
you can make it to 1000 like this :

ActiveSheet.Range("$A$1:$A$1000")

Fiddler listens to outbound requests rather than inbound requests so you're not going to be able to monitor all the requests coming in to your service by using Fiddler.

The best you're going to get with Fiddler is the ability to see all of the requests as they are generated by your Console App (assuming that the app generates web requests rather than using some other pipeline).

If you want a tool that is more powerful (but more difficult to use) that will allow you to monitor ALL incoming requests, you should check out WireShark.

Edit

I stand corrected. Thanks to Eric Law for posting the directions to configuring Fiddler to be a reverse proxy!

If you're working with images, you might actually prefer to not use a bias at all. In theory, that way your network will be more independent of data magnitude, as in whether the picture is dark, or bright and vivid. And the net is going to learn to do it's job through studying relativity inside your data. Lots of modern neural networks utilize this.

For other data having biases might be critical. It depends on what type of data you're dealing with. If your information is magnitude-invariant --- if inputting [1,0,0.1] should lead to the same result as if inputting [100,0,10], you might be better off without a bias.

A quick, plugin-free way to preload images in jQuery and get a callback function is to create multiple img tags at once and count the responses, e.g.

function preload(files, cb) {
    var len = files.length;
    $(files.map(function(f) {
        return '<img src="'+f+'" />';
    }).join('')).load(function () {
        if(--len===0) {
            cb();
        }
    });
}

preload(["one.jpg", "two.png", "three.png"], function() {
    /* Code here is called once all files are loaded. */
});
?    ?

Note that if you want to support IE7, you'll need to use this slightly less pretty version (Which also works in other browsers):

function preload(files, cb) {
    var len = files.length;
    $($.map(files, function(f) {
        return '<img src="'+f+'" />';
    }).join('')).load(function () {
        if(--len===0) {
            cb();
        }
    });
}

I created an insecure but simple text cipher/decipher util. No dependencies with any external library.

These are the functions

const cipher = salt => {
    const textToChars = text => text.split('').map(c => c.charCodeAt(0));
    const byteHex = n => ("0" + Number(n).toString(16)).substr(-2);
    const applySaltToChar = code => textToChars(salt).reduce((a,b) => a ^ b, code);

    return text => text.split('')
        .map(textToChars)
        .map(applySaltToChar)
        .map(byteHex)
        .join('');
}

const decipher = salt => {
    const textToChars = text => text.split('').map(c => c.charCodeAt(0));
    const applySaltToChar = code => textToChars(salt).reduce((a,b) => a ^ b, code);
    return encoded => encoded.match(/.{1,2}/g)
        .map(hex => parseInt(hex, 16))
        .map(applySaltToChar)
        .map(charCode => String.fromCharCode(charCode))
        .join('');
}

And you can use them as follows:

// To create a cipher
const myCipher = cipher('mySecretSalt')

//Then cipher any text:
myCipher('the secret string')   // --> "7c606d287b6d6b7a6d7c287b7c7a61666f"

//To decipher, you need to create a decipher and use it:
const myDecipher = decipher('mySecretSalt')
myDecipher("7c606d287b6d6b7a6d7c287b7c7a61666f")    // --> 'the secret string'

I created an enhanced version, based on Trey Copland's fiddle, that I think is more like what you wanted. Added here for future reference to those who come here later. Fiddle example

Update 2019/05 Now this can be done in the JetBrains Toolbox app. You can set it once with the Toolbox, for all of your JetBrain IDEs.

As of 2019.1 EAP, the Create Commmand Line Launcher option is not available in the Tools menu anymore. My solution is to use the following alias in my bash/zsh profile:

Make sure that you run chmod -x ...../pycharm to make the binary executable.

# in your ~/.profile or other rc file to the effect.

alias pycharm="open -a '$(ls -r /Users/geyang/Library/Application\ Support/JetBrains/Toolbox/apps/PyCharm-P/**/PyCharm*.app/Contents/MacOS/pycharm)'"

Why so complicated? You don't even need jQuery because there is a HTML5 pattern attribute:

<input type="text" pattern="[0-9]*">

The cool thing is that it brings up a numeric keyboard on mobile devices, which is way better than using jQuery.

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

This is the command you'd run from terminal*

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

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

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

If you have to deal with NTLM proxy authentication a good alternative is to use a configure a local proxy using CNTLM.

The credentials and domain are configured in /etc/cntlm.conf.

Afterwards you can just use you own proxy that handles all the NTLM stuff.

DesiredCapabilities capabilities = DesiredCapabilities.chrome();

Proxy proxy = new Proxy();
proxy.setHttpProxy("localhost:3128");
capabilities.setCapability(CapabilityType.PROXY, proxy);

driver = new ChromeDriver(capabilities);

Great question and great idea, but in SQL you'll need to do this:

For data type datetime, something like this-

declare @BeginDate    datetime = '1/1/2016',
        @EndDate      datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
   while @var < dateadd(MONTH, +1, @EndDate)
   Begin
          insert into #months Values(@var)
          set @var = Dateadd(MONTH, +1, @var)
   end

If all you really want is numbers, do this-

create table #numbas (digit int)
declare @var int = 1        --your starting digit
    while @var <= 12        --your ending digit
    begin
        insert into #numbas Values(@var)
        set @var = @var +1
    end

The indexing e.g. [0] should occour inside of the print...

Why not loop through the inputs and then add onclick handlers to each?

You don't have to do this in HTML, but you can add a handler to each button like:

button.onclick = function(){ DoStuff(this.value); return false; } // return false; so that form does not submit

Then your function could "do stuff" according to whichever value you passed:

function DoStuff(val) {
    if( val === "Val 1" ) {
        // Do some stuff
    }
    // Do other stuff
}

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

A nice way of doing this is to use the addObserver(forName:object:queue:using:) method rather than the addObserver(_:selector:name:object:) method that is often used from Objective-C code. The advantage of the first variant is that you don't have to use the @objc attribute on your method:

    func batteryLevelChanged(notification: Notification) {
        // do something useful with this information
    }

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil,
        using: batteryLevelChanged)

and you can even just use a closure instead of a method if you want:

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil) { _ in print("") }

You can use the returned value to stop listening for the notification later:

    NotificationCenter.default.removeObserver(observer)

There used to be another advantage in using this method, which was that it doesn't require you to use selector strings which couldn't be statically checked by the compiler and so were fragile to breaking if the method is renamed, but Swift 2.2 and later include #selector expressions that fix that problem.

You can use Canary version of Chrome to see request payload of POST requests.

Use the HorizontalAlignment and VerticalAlignment layout properties. They control how an element uses the space it has inside its parent when more room is available than it required by the element.

The width of a StackPanel, for example, will be as wide as the widest element it contains. So, all narrower elements have a bit of excess space. The alignment properties control what the child element does with the extra space.

The default value for both properties is Stretch, so the child element is stretched to fill all available space. Additional options include Left, Center and Right for HorizontalAlignment and Top, Center and Bottom for VerticalAlignment.

This should give you the current date minus 1 year:

select now() - interval '1 year';

You need both a value and a field to assign it to. The value is TableField + 1, so the assignment is:

SET TableField = TableField + 1

In your connection string replace server=localhost with "server = Paul-PC\\SQLEXPRESS;"

Just do

Replace:

myBinding.Source = ViewModel.SomeString;

with:

myBinding.Source = ViewModel;

Example:

Binding myBinding = new Binding();
myBinding.Source = ViewModel;
myBinding.Path = new PropertyPath("SomeString");
myBinding.Mode = BindingMode.TwoWay;
myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(txtText, TextBox.TextProperty, myBinding);

Your source should be just ViewModel, the .SomeString part is evaluated from the Path (the Path can be set by the constructor or by the Path property).

How about this one?

import signal
signal.pause()

This will let your program sleep until it receives a signal from some other process (or itself, in another thread), letting it know it is time to do something.

I just noticed recently that when I used write() on a socket in Windows, it almost works (the FD passed to write() isn't the same as the one passed to send(); I used _open_osfhandle() to get the FD to pass to write()). However, it didn't work when I tried to send binary data that included character 10. write() somewhere inserted character 13 before this. Changing it to send() with a flags parameter of 0 fixed that problem. read() could have the reverse problem if 13-10 are consecutive in the binary data, but I haven't tested it. But that appears to be another possible difference between send() and write().

ActiveRecord stores validation errors in an array called errors. If you have a User model then you would access the validation errors in a given instance like so:

@user = User.create[params[:user]] # create will automatically call validators

if @user.errors.any? # If there are errors, do something

  # You can iterate through all messages by attribute type and validation message
  # This will be something like:
  # attribute = 'name'
  # message = 'cannot be left blank'
  @user.errors.each do |attribute, message|
    # do stuff for each error
  end

  # Or if you prefer, you can get the full message in single string, like so:
  # message = 'Name cannot be left blank'
  @users.errors.full_messages.each do |message|
    # do stuff for each error
  end

  # To get all errors associated with a single attribute, do the following:
  if @user.errors.include?(:name)
    name_errors = @user.errors[:name]

    if name_errors.kind_of?(Array)
      name_errors.each do |error|
        # do stuff for each error on the name attribute
      end
    else
      error = name_errors
      # do stuff for the one error on the name attribute.
    end
  end
end

Of course you can also do any of this in the views instead of the controller, should you want to just display the first error to the user or something.

Use:

select convert(nvarchar(10), CREATED_TS, 101)

or

select format(cast(CREATED_TS as date), 'MM/dd/yyyy') -- MySQL 3.23 and above

Not tested, but should work.. And yes, it could be better implemented with fread, I'll leave that as an exercise to the reader.

#define DEFAULT_SIZE 100
#define STEP_SIZE 100

char *buffer[DEFAULT_SIZE];
size_t buffer_sz=DEFAULT_SIZE;
size_t i=0;
while(!feof(fp)){
  buffer[i]=fgetc(fp);
  i++;
  if(i>=buffer_sz){
    buffer_sz+=STEP_SIZE;
    void *tmp=buffer;
    buffer=realloc(buffer,buffer_sz);
    if(buffer==null){ free(tmp); exit(1);} //ensure we don't have a memory leak
  }
}
buffer[i]=0;

The following statement causes a user's password to expire:

ALTER USER user PASSWORD EXPIRE;

If you cause a database user's password to expire with PASSWORD EXPIRE, then the user (or the DBA) must change the password before attempting to log in to the database following the expiration. Tools such as SQL*Plus allow the user to change the password on the first attempted login following the expiration.

ALTER USER scott IDENTIFIED BY password;

Will set/reset the users password.

See the alter user doc for more info

Here's my take if you want to try using multiprocesses to process each row of numpy array,

from multiprocessing import Pool
import numpy as np

def my_function(x):
    pass     # do something and return something

if __name__ == '__main__':    
    X = np.arange(6).reshape((3,2))
    pool = Pool(processes = 4)
    results = pool.map(my_function, map(lambda x: x, X))
    pool.close()
    pool.join()

pool.map take in a function and an iterable.
I used 'map' function to create an iterator over each rows of the array.
Maybe there's a better to create the iterable though.

It's better not to use refs in such cases. Use:

<input
    type="checkbox"
    checked={this.state.active}
    onClick={this.handleClick}
/>

There are some options:

checked vs defaultChecked

The former would respond to both state changes and clicks. The latter would ignore state changes.

onClick vs onChange

The former would always trigger on clicks. The latter would not trigger on clicks if checked attribute is present on input element.

Old question, but there's an easier way.

sns.pointplot(x=x_col,y=y_col,data=df_1,color='blue')
sns.pointplot(x=x_col,y=y_col,data=df_2,color='green')
sns.pointplot(x=x_col,y=y_col,data=df_3,color='red')
plt.legend(labels=['legendEntry1', 'legendEntry2', 'legendEntry3'])

This lets you add the plots sequentially, and not have to worry about any of the matplotlib crap besides defining the legend items.

#FFFFEEE is not a correct color code. Try with #FFFFEE instead.

This Is Work For Me.

Locale-independent one liner to get any date format you like. I use it to generate archive names. Back quote option is needed because PowerShell command line is using single quotes.

:: Get date in yyyyMMdd_HHmm format to use with file name.
FOR /f "usebackq" %%i IN (`PowerShell ^(Get-Date^).ToString^('yyyy-MM-dd'^)`) DO SET DTime=%%i

:: Get formatted yesterday date.
FOR /f "usebackq" %%i IN (`PowerShell ^(Get-Date^).AddDays^(-1^).ToString^('yyyy-MM-dd'^)`) DO SET DTime=%%i

:: Show file name with the date.
echo Archive.%DTime%.zip

I just ran into this issue, on the gpg CLI in Arch Linux. I needed to kill the existing "gpg-agent" process, then everything was back to normal ( a new gpg-agent should auto-launch when you invoke the gpg command, again; ...).

• edit: if the process fails to reload (e.g. within a minute), type gpg-agent in a terminal and/or reboot ...

var elem = document.querySelector(".a.b");

Your regex pattern should have the g modifier:

var pattern = /[somepattern]+/g;

notice the g at the end. it tells the replacer to do a global replace.

Also you dont need to use the RegExp object you can construct your pattern as above. Example pattern:

var pattern = /[0-9a-zA-Z]+/g;

a pattern is always surrounded by / on either side - with modifiers after the final /, the g modifier being the global.

EDIT: Why does it matter if pattern is a variable? In your case it would function like this (notice that pattern is still a variable):

var pattern = /[0-9a-zA-Z]+/g;
repeater.replace(pattern, "1234abc");

But you would need to change your replace function to this:

this.markup = this.markup.replace(pattern, value);

Use this:

Format(Now, "MMMM dd, yyyy")

I am not sure if this is the best solution or not, but it is what I need.

Brutal, yet elegant.

if needed programmatic from a PDE or JDT code:

public static void setWorkspaceAutoBuild(boolean flag) throws CoreException 
{
IWorkspace workspace = ResourcesPlugin.getWorkspace();
final IWorkspaceDescription description = workspace.getDescription();
description.setAutoBuilding(flag);
workspace.setDescription(description);
}

Similarly in Java, you can create a S4 class in R that encapsulates your information:

setClass(Class="Person",
         representation(
            height="numeric",
            age="numeric"
          )
)

Then your function can return an instance of this class:

myFunction = function(age=28, height=176){
  return(new("Person",
          age=age,
          height=height))
}

and you can access your information:

aPerson = myFunction()

aPerson@age
aPerson@height

A lot of C projects end up implementing a vector-like API. Dynamic arrays are such a common need, that it's nice to abstract away the memory management as much as possible. A typical C implementation might look something like:

typedef struct dynamic_array_struct
{
  int* data;
  size_t capacity; /* total capacity */
  size_t size; /* number of elements in vector */
} vector;

Then they would have various API function calls which operate on the vector:

int vector_init(vector* v, size_t init_capacity)
{
  v->data = malloc(init_capacity * sizeof(int));
  if (!v->data) return -1;

  v->size = 0;
  v->capacity = init_capacity;

  return 0; /* success */
}

Then of course, you need functions for push_back, insert, resize, etc, which would call realloc if size exceeds capacity.

vector_resize(vector* v, size_t new_size);

vector_push_back(vector* v, int element);

Usually, when a reallocation is needed, capacity is doubled to avoid reallocating all the time. This is usually the same strategy employed internally by std::vector, except typically std::vector won't call realloc because of C++ object construction/destruction. Rather, std::vector might allocate a new buffer, and then copy construct/move construct the objects (using placement new) into the new buffer.

An actual vector implementation in C might use void* pointers as elements rather than int, so the code is more generic. Anyway, this sort of thing is implemented in a lot of C projects. See http://codingrecipes.com/implementation-of-a-vector-data-structure-in-c for an example vector implementation in C.

Godaddy Installation Tips

jQuery UI has a :data() selector which can also be used. It has been around since Version 1.7.0 it seems.

You can use it like this:

Get all elements with a data-company attribute

var companyElements = $("ul:data(group) li:data(company)");

Get all elements where data-company equals Microsoft

var microsoft = $("ul:data(group) li:data(company)")
                    .filter(function () {
                        return $(this).data("company") == "Microsoft";
                    });

Get all elements where data-company does not equal Microsoft

var notMicrosoft = $("ul:data(group) li:data(company)")
                       .filter(function () {
                           return $(this).data("company") != "Microsoft";
                       });

etc...

One caveat of the new :data() selector is that you must set the data value by code for it to be selected. This means that for the above to work, defining the data in HTML is not enough. You must first do this:

$("li").first().data("company", "Microsoft");

This is fine for single page applications where you are likely to use $(...).data("datakey", "value") in this or similar ways.

I'd suggest to use jshint instead.

It allows to suppress this warning via /*jshint globalstrict: true*/.

If you are writing a library, I would only suggest using global strict if your code is encapsulated into modules as is the case with nodejs.

Otherwise you'd force everyone who is using your library into strict mode.

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

Source: is there a way to serialize pojo's directly to treemodel?

For those that implemented react js in some part of the website and encounter this issue. Just add a condition to check if the element exist on that page before you render the react component.

<div id="element"></div>

...

const someElement = document.getElementById("element")
    
if(someElement) {
  ReactDOM.render(<Yourcomponent />, someElement)
}

Here is another example using the lapply and table functions in base R.

freqList = lapply(select_if(tips, is.factor), 
              function(x) {
                  df = data.frame(table(x))

                  df = data.frame(fct = df[, 1], 
                                  n = sapply(df[, 2], function(y) {
                                      round(y / nrow(dat), 2)
                                    }
                                )
                            )
                  return(df) 
                    }
                )

Use print(freqList) to see the proportion tables (percent of frequencies) for each column/feature/variable (depending on your tradecraft) that is labeled as a factor.

While the code to create a custom Attribute is fairly simple, it's very important that you understand what attributes are:

Attributes are metadata compiled into your program. Attributes themselves do not add any functionality to a class, property or module - just data. However, using reflection, one can leverage those attributes in order to create functionality.

So, for instance, let's look at the Validation Application Block, from Microsoft's Enterprise Library. If you look at a code example, you'll see:

    /// <summary>
    /// blah blah code.
    /// </summary>
    [DataMember]
    [StringLengthValidator(8, RangeBoundaryType.Inclusive, 8, RangeBoundaryType.Inclusive, MessageTemplate = "\"{1}\" must always have \"{4}\" characters.")]
    public string Code { get; set; }

From the snippet above, one might guess that the code will always be validated, whenever changed, accordingly to the rules of the Validator (in the example, have at least 8 characters and at most 8 characters). But the truth is that the Attribute does nothing; as mentioned previously, it only adds metadata to the property.

However, the Enterprise Library has a Validation.Validate method that will look into your object, and for each property, it'll check if the contents violate the rule informed by the attribute.

So, that's how you should think about attributes -- a way to add data to your code that might be later used by other methods/classes/etc.

Assuming you are on Windows (this bug is caused by the crappy bat files escaping), It is a bug introduced in the latest versions (7.0.56 and 8.0.14) to workaround another bug. Try to remove the " around the JAVA_OPTS declaration in catalina.bat. It fixed it for me with Tomcat 7.0.56 yesterday.

In 7.0.56 in bin/catalina.bat:179 and 184

:noJuliConfig
set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%"

..

:noJuliManager
set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%"

to

:noJuliConfig
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%

.. 

:noJuliManager
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%

For your asterisk, it might only be a configuration of yours somewhere that appends it to the host declaration.

I saw this on Tomcat's bugtracker yesterday but I can't find the link again. Edit Found it! https://issues.apache.org/bugzilla/show_bug.cgi?id=56895

I hope it fixes your problem.

I just discovered that the Mock library provides an assertRaisesWithMessage() method (in its unittest.TestCase subclass), which will check not only that the expected exception is raised, but also that it is raised with the expected message:

from testcase import TestCase

import mymod

class MyTestCase(TestCase):
    def test1(self):
        self.assertRaisesWithMessage(SomeCoolException,
                                     'expected message',
                                     mymod.myfunc)

There is this MarkerClusterer client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:

There are many approaches for doing what you asked for:

• Grid based clustering
• Distance based clustering
• Viewport Marker Management
• Fusion Tables
• Marker Clusterer
• MarkerManager

You can read about them on the provided link above.

Marker Clusterer uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.

Before Clustering

After Clustering

I hope this is what you were looking for & this will solve your problem :)

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

Config->Apache->Open httpd.conf. search for Listen or 80,update listen port to 8081 save and restart server. Oh and shutdown Skype if you have it.

Normally, IIS would use the process identity (the user account it is running the worker process as) to access protected resources like file system or network.

With passthrough authentication, IIS will attempt to use the actual identity of the user when accessing protected resources.

If the user is not authenticated, IIS will use the application pool identity instead. If pool identity is set to NetworkService or LocalSystem, the actual Windows account used is the computer account.

The IIS warning you see is not an error, it's just a warning. The actual check will be performed at execution time, and if it fails, it'll show up in the log.

I feel the following is of greater clarity and customization than other answers.

    var element_to_blink=$('#id_of_element_to_blink');
    var min_opacity=0.2;
    var max_opacity=1.0;
    var blink_duration=2000;
    var blink_quantity=10;
    var current_blink_number=0;

    while(current_blink_number<blink_quantity){
        element_to_blink.animate({opacity:min_opacity},(blink_duration/2),"linear");
        element_to_blink.animate({opacity:max_opacity},(blink_duration/2),"linear");
        current_blink_number+=1;
        }

It depends on nature of your data. The answer varies based on its size and data type. I saw a lot of SQL solutions based on ORDER BY. I would like to suggest javascript alternatives.

In all answers, I don't see anyone mentioning pagination problem for your future table. Let's make it easier for you. If your table doesn't have pagination, it's more likely that a javascript solution makes everything neat and clean for you on the client side. If you think this table will explode after you put data in it, you have to think about pagination as well. (you have to go to first page every time when you change the sorting column)

Another aspect is the data type. If you use SQL you have to be careful about the type of your data and what kind of sorting suites for it. For example, if in one of your VARCHAR columns you store integer numbers, the sorting will not take their integer value into account: instead of 1, 2, 11, 22 you will get 1, 11, 2, 22.

You can find jquery plugins or standalone javascript sortable tables on google. It worth mentioning that the <table> in HTML5 has sortable attribute, but apparently it's not implemented yet.

fedorqui has a working solution but there is another way to do the same thing.

Chock if a variable is set

#!/bin/bash
amIEmpty='Hello'
# This will be true if the variable has a value
if [ $amIEmpty ]; then
    echo 'No, I am not!';
fi

Or to verify that a variable is empty

#!/bin/bash      
amIEmpty=''
# This will be true if the variable is empty
if [ ! $amIEmpty ]; then
    echo 'Yes I am!';
fi

tldp.org has good documentation about if in bash:
http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html

We can update GTF answer to update timestamps easily

$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=>date('Y-m-d H:i:s'),
        'modified_at'=> date('Y-m-d H:i:s')
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=>date('Y-m-d H:i:s'),
         'modified_at'=> date('Y-m-d H:i:s')
       ),
    //...
);

Coder::insert($data);

Update: to simplify the date we can use carbon as @Pedro Moreira suggested

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'modified_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'modified_at'=> $now
       ),
    //...
);

Coder::insert($data);

UPDATE2: for laravel 5 , use updated_at instead of modified_at

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'updated_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'updated_at'=> $now
       ),
    //...
);

Coder::insert($data);

Now you need 1 adapter for all RecyclerView

• One adapter can be used in for all RecyclerView. So NO onBindViewHolder, No onCreateViewHolder handling.
• No code for setting adapter from Java/Kotlin class. Check sample class.
• You can set events and custom data for every list by using Binding Adapters.

I show here setting two different RecyclerView by 1 adapter -

activity_home.xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

    <data>

        <variable
            name="listOne"
            type="java.util.List"/>

        <variable
            name="listTwo"
            type="java.util.List"/>

        <variable
            name="onItemClickListenerOne"
            type="com.ks.nestedrecyclerbindingexample.callbacks.OnItemClickListener"/>

        <variable
            name="onItemClickListenerTwo"
            type="com.ks.nestedrecyclerbindingexample.callbacks.OnItemClickListener"/>

    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            rvItemLayout="@{@layout/row_one}"
            rvList="@{listOne}"
            rvOnItemClick="@{onItemClickListenerOne}"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layoutManager="android.support.v7.widget.LinearLayoutManager"
            />

        <android.support.v7.widget.RecyclerView
            rvItemLayout="@{@layout/row_two}"
            rvList="@{listTwo}"
            rvOnItemClick="@{onItemClickListenerTwo}"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layoutManager="android.support.v7.widget.LinearLayoutManager"
            />

    </LinearLayout>

</layout>

You can see I pass list, item layout id and click listener from layout.

rvItemLayout="@{@layout/row_one}"
rvList="@{listOne}"
rvOnItemClick="@{onItemClickListenerOne}"

This custom attributes are created by BindingAdapter.

public class BindingAdapters {
    @BindingAdapter(value = {"rvItemLayout", "rvList", "rvOnItemClick"}, requireAll = false)
    public static void setRvAdapter(RecyclerView recyclerView, int rvItemLayout, List rvList, @Nullable OnItemClickListener onItemClickListener) {
        if (rvItemLayout != 0 && rvList != null && rvList.size() > 0)
            recyclerView.setAdapter(new GeneralAdapter(rvItemLayout, rvList, onItemClickListener));
    }
}

Now from Activity, you pass list, click listener like

HomeActivity.java

public class HomeActivity extends AppCompatActivity {
    ActivityHomeBinding binding;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = DataBindingUtil.setContentView(this, R.layout.activity_home);
        binding.setListOne(new ArrayList()); // pass your list or set list from response of API
        binding.setListTwo(new ArrayList());
        binding.setOnItemClickListenerOne(new OnItemClickListener() {

You don't want read too much, directly clone/download full example on from my github repo. And try it yourself.

You can see GeneralAdapter.java in above repo.

If you have problems while setting up data binding, please see this answer.

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

To be honest I like the OP's first way of actually starting it with a NULL value and then checking it with is.null (primarily because it is very simply and easy to understand). It maybe depends on the way people are used to coding but the Hadley seems to support the is.null way too:

From Hadley's book "Advanced-R" Chapter 6, Functions, p.84 (for the online version check here):

You can determine if an argument was supplied or not with the missing() function.

i <- function(a, b) {
  c(missing(a), missing(b))
}
i()
#> [1] TRUE TRUE
i(a = 1)
#> [1] FALSE  TRUE
i(b = 2)
#> [1]  TRUE FALSE
i(1, 2)
#> [1] FALSE FALSE

Sometimes you want to add a non-trivial default value, which might take several lines of code to compute. Instead of inserting that code in the function definition, you could use missing() to conditionally compute it if needed. However, this makes it hard to know which arguments are required and which are optional without carefully reading the documentation. Instead, I usually set the default value to NULL and use is.null() to check if the argument was supplied.

You can use settype method too!

SetType($var,"Boolean") Echo $var //see 0 or 1

The shortest way would probably be to use the fileinput module. For example, the following adds line numbers to a file, in-place:

import fileinput

for line in fileinput.input("test.txt", inplace=True):
    print('{} {}'.format(fileinput.filelineno(), line), end='') # for Python 3
    # print "%d: %s" % (fileinput.filelineno(), line), # for Python 2

What happens here is:

1. The original file is moved to a backup file
2. The standard output is redirected to the original file within the loop
3. Thus any print statements write back into the original file

fileinput has more bells and whistles. For example, it can be used to automatically operate on all files in sys.args[1:], without your having to iterate over them explicitly. Starting with Python 3.2 it also provides a convenient context manager for use in a with statement.

While fileinput is great for throwaway scripts, I would be wary of using it in real code because admittedly it's not very readable or familiar. In real (production) code it's worthwhile to spend just a few more lines of code to make the process explicit and thus make the code readable.

There are two options:

1. The file is not overly large, and you can just read it wholly to memory. Then close the file, reopen it in writing mode and write the modified contents back.
2. The file is too large to be stored in memory; you can move it over to a temporary file and open that, reading it line by line, writing back into the original file. Note that this requires twice the storage.

In some languages this can be solved with tail call optimization, where the recursion call is transformed under the hood into a loop so no maximum stack size reached error exists.

But in javascript the current engines don't support this, it's foreseen for new version of the language Ecmascript 6.

Node.js has some flags to enable ES6 features but tail call is not yet available.

So you can refactor your code to implement a technique called trampolining, or refactor in order to transform recursion into a loop.

I guess something like this would work:

Add System.ServiceProcess to your project references (It's on the .NET tab).

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Edit: There is also a method sc.WaitforStatus() that takes a desired status and a timeout, never used it but it may suit your needs.

Edit: Once you get the status, to get the status again you will need to call sc.Refresh() first.

Reference: ServiceController object in .NET.

You can simply use if(yourElement)

var a = document.getElementById("elemA");_x000D_
var b = document.getElementById("elemB");_x000D_
_x000D_
if(a)_x000D_
  console.log("elemA exists");_x000D_
else_x000D_
  console.log("elemA does not exist");_x000D_
  _x000D_
if(b)_x000D_
  console.log("elemB exists");_x000D_
else_x000D_
  console.log("elemB does not exist");

<div id="elemA"></div>

In Python2, input is evaluated, input() is equivalent to eval(raw_input()). When you enter klj, Python tries to evaluate that name and raises an error because that name is not defined.

Use raw_input to get a string from the user in Python2.

Demo 1: klj is not defined:

>>> input()
klj
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'klj' is not defined

Demo 2: klj is defined:

>>> klj = 'hi'
>>> input()
klj
'hi'

Demo 3: getting a string with raw_input:

>>> raw_input()
klj
'klj'

I had the same problem, here's how I solved it. Following the first section of this very excellent Django tutorial, I did the following:

1. Create a new Django app by executing: python manage.py startapp new_app
2. Edit the settings.py file, adding the following to the list of INSTALLED_APPS: 'new_app',
3. Add a new module to the new_app package named new_app_tags.
4. In a Django HTML template, add the following to the top of the file, but after {% extends 'base_template_name.html' %}: {% load new_app_tags %}
5. In the new_app_tags module file, create a custom template tag (see below).
6. In the same Django HTML template, from step 4 above, use your shiney new custom tag like so: {% multiply_by_two | "5.0" %}
7. Celebrate!

Example from step 5 above:

from django import template

register = template.Library()

@register.simple_tag
def multiply_by_two(value):
    return float(value) * 2.0

asarray(x) is like array(x, copy=False)

Use asarray(x) when you want to ensure that x will be an array before any other operations are done. If x is already an array then no copy would be done. It would not cause a redundant performance hit.

Here is an example of a function that ensure x is converted into an array first.

def mysum(x):
    return np.asarray(x).sum()

It's entirely possible if your code has enough relative logic to work with.

Simply use the viewport units though for some the math may be a bit more complicated. I used this to prevent list items from bloating certain table columns with much longer text.

ol {max-width: 10vw; padding: 0; overflow: hidden;}

Apparently max-width on colgroup elements do not work which is pretty lame to be dependent entirely on child elements to control something on the parent.

Active Directory does not store the group membership on user objects. It only stores the Member list on the group. The tools show the group membership on user objects by doing queries for it.

How about:

(&(objectClass=group)(member=cn=my,ou=full,dc=domain))

(You forgot the (& ) bit in your example in the question as well).

I had the same issue with CakePHP 2.0.1

I tried using

header( 'HTTP/1.1 400 BAD REQUEST' );

and

$this->header( 'HTTP/1.1 400 BAD REQUEST' );

However, neither of these solved my issue.

I did eventually resolve it by using

$this->header( 'HTTP/1.1 400: BAD REQUEST' );

After that, no errors or warning from php / CakePHP.

*edit: In the last $this->header function call, I put a colon (:) between the 400 and the description text of the error.

this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.

to check either a pointer is initialized or not you can try something like

Class *pointer = new Class();
if(pointer!=nullptr){
    pointer->myFunction();
}

For sending data to a service you can use:

Intent intent = new Intent(getApplicationContext(), YourService.class);
intent.putExtra("SomeData","ItValue");
startService(intent);

And after in service in onStartCommand() get data from intent.

For sending data or event from a service to an application (for one or more activities):

private void sendBroadcastMessage(String intentFilterName, int arg1, String extraKey) {
    Intent intent = new Intent(intentFilterName);
    if (arg1 != -1 && extraKey != null) {
        intent.putExtra(extraKey, arg1);
    }
    sendBroadcast(intent);
}

This method is calling from your service. You can simply send data for your Activity.

private void someTaskInYourService(){

    //For example you downloading from server 1000 files
    for(int i = 0; i < 1000; i++) {
        Thread.sleep(5000) // 5 seconds. Catch in try-catch block
        sendBroadCastMessage(Events.UPDATE_DOWNLOADING_PROGRESSBAR, i,0,"up_download_progress");
    }

For receiving an event with data, create and register method registerBroadcastReceivers() in your activity:

private void registerBroadcastReceivers(){
    broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            int arg1 = intent.getIntExtra("up_download_progress",0);
            progressBar.setProgress(arg1);
        }
    };
    IntentFilter progressfilter = new IntentFilter(Events.UPDATE_DOWNLOADING_PROGRESS);
    registerReceiver(broadcastReceiver,progressfilter);

For sending more data, you can modify method sendBroadcastMessage();. Remember: you must register broadcasts in onResume() & unregister in onStop() methods!

UPDATE

Please don't use my type of communication between Activity & Service. This is the wrong way. For a better experience please use special libs, such us:

1) EventBus from greenrobot

2) Otto from Square Inc

P.S. I'm only using EventBus from greenrobot in my projects,

I too had this problem. But apparently there is an issue of the order of method calls. You must call:

[self.picker selectRow:2 inComponent:0 animated:YES];

after calling

[self.view addSubview:self.picker];

For anybody reading this in the future, here is a simpler answer:

var s = "11:41:02PM";
var time = s.match(/\d{2}/g);
if (time[0] === "12") time[0] = "00";
if (s.indexOf("PM") > -1) time[0] = parseInt(time[0])+12;
return time.join(":");

Use this version of the assert statement to provide a detail message for the AssertionError. The system passes the value of Expression2 to the appropriate AssertionError constructor, which uses the string representation of the value as the error's detail message.

The purpose of the detail message is to capture and communicate the details of the assertion failure. The message should allow you to diagnose and ultimately fix the error that led the assertion to fail. Note that the detail message is not a user-level error message, so it is generally unnecessary to make these messages understandable in isolation, or to internationalize them. The detail message is meant to be interpreted in the context of a full stack trace, in conjunction with the source code containing the failed assertion.

JavaDoc

As stated by Oracle, JavaFX is the next step in their Java based rich client strategy. Accordingly, this is what I recommend for your situation:

What would be easier and cleaner to maintain

• JavaFX has introduced several improvements over Swing, such as, possibility to markup UIs with FXML, and theming with CSS. It has great potential to write a modular, clean & maintainable code.

What would be faster to build from scratch

• This is highly dependent on your skills and the tools you use.
  • For swing, various IDEs offer tools for rapid development. The best I personally found is the GUI builder in NetBeans.
  • JavaFX has support from various IDEs as well, though not as mature as the support Swing has at the moment. However, its support for markup in FXML & CSS make GUI development on JavaFX intuitive.

MVC Pattern Support

• JavaFX is very friendly with MVC pattern, and you can cleanly separate your work as: presentation (FXML, CSS), models(Java, domain objects) and logic(Java).
• IMHO, the MVC support in Swing isn't very appealing. The flow you'll see across various components lacks consistency.

For more info, please take a look these FAQ post by Oracle regarding JavaFX here.

Hope that helps anyone finding an answer this question in the future; compiling dosbox needs this, for instance, due to SDL opengl.

To clarify, the above example does work, my code in the example did not work for unrelated reasons.

If myvar is false, null or has never been used before (i.e. $scope.myvar or $rootScope.myvar never called), the div will not show. Once any value has been assigned to it, the div will show, except if the value is specifically false.

The following will cause the div to show:

$scope.myvar = "Hello World";

or

$scope.myvar = true;

The following will hide the div:

$scope.myvar = null;

or

$scope.myvar = false;

I believe that is is a move operator. operator= is the assignment operator, say vector x = vector y. The clear() function call sounds like as if it is deleting the contents of the vector to prevent a memory leak. The operator returns a pointer to the new vector.

This way,

std::vector<int> a(100, 10);
std::vector<int> b = a;
for(unsigned int i = 0; i < b.size(); i++)
{
    std::cout << b[i] << ' ';
}

Even though we gave vector a values, vector b has the values. It's the magic of the operator=()!

MSDN -- How to create a move constructor

/// <summary>
/// Returns a string With count chars Left or Right value
/// </summary>
/// <param name="val"></param>
/// <param name="count"></param>
/// <param name="space"></param>
/// <param name="right"></param>
/// <returns></returns>
 public static string Formating(object val, int count, char space = ' ', bool right = false)
{
    var value = val.ToString();
    for (int i = 0; i < count - value.Length; i++) value = right ? value + space : space + value;
    return value;
}

Use this code if you have nested objects or if you have nested array obj.

var sortObjectByKey = function(obj){
    var keys = [];
    var sorted_obj = {};
    for(var key in obj){
        if(obj.hasOwnProperty(key)){
            keys.push(key);
        }
    }
    // sort keys
    keys.sort();

    // create new array based on Sorted Keys
    jQuery.each(keys, function(i, key){
        var val = obj[key];
        if(val instanceof Array){
            //do for loop;
            var arr = [];
            jQuery.each(val,function(){
                arr.push(sortObjectByKey(this));
            }); 
            val = arr;

        }else if(val instanceof Object){
            val = sortObjectByKey(val)
        }
        sorted_obj[key] = val;
    });
    return sorted_obj;
};

Do you mean catch an Exception of any type that is thrown, as opposed to just specific Exceptions?

If so:

try {
   //...file IO...
} catch(Exception e) {
   //...do stuff with e, such as check its type or log it...
}

You can do that with datetime.strptime()

Example:

>>> from datetime import datetime
>>> datetime.strptime('2012-02-10' , '%Y-%m-%d')
datetime.datetime(2012, 2, 10, 0, 0)
>>> _.isoweekday()
5

You can find the table with all the strptime directive here.

To increment by 2 days if .isweekday() == 6, you can use timedelta():

>>> import datetime
>>> date = datetime.datetime.strptime('2012-02-11' , '%Y-%m-%d')
>>> if date.isoweekday() == 6:
...     date += datetime.timedelta(days=2)
... 
>>> date
datetime.datetime(2012, 2, 13, 0, 0)
>>> date.strftime('%Y-%m-%d')   # if you want a string again
'2012-02-13'

Closing the solution completely and rerunning the project solved my issue.

For anyone in the future looking for an answer, I would like to give a much clearer answer to the question.

# for making a tuple
my_tuple = (89, 32)
my_tuple_with_more_values = (1, 2, 3, 4, 5, 6)

# to concatenate tuples
another_tuple = my_tuple + my_tuple_with_more_values
print(another_tuple)
# (89, 32, 1, 2, 3, 4, 5, 6)

# getting a value from a tuple is similar to a list
first_val = my_tuple[0]
second_val = my_tuple[1]

# if you have a function called my_tuple_fun that returns a tuple,
# you might want to do this
my_tuple_fun()[0]
my_tuple_fun()[1]

# or this
v1, v2 = my_tuple_fun()

Hope this clears things up further for those that need it.

If you installed mysql through brew then we can use command to uninstall mysql.

$ brew uninstall mysql

Uninstalling /usr/local/Cellar/mysql/5.6.19...

This worked for me.

I would think that one reason could be that the color is applied to things other than font. For example:

div {
    border: 1px solid;
    color: red;
}

Yields both a red font color and a red border.

Alternatively, it could just be that the W3C's CSS standards are completely backwards and nonsensical as evidenced elsewhere.

Use Heredocs to output muli-line strings containing variables. The syntax is...

$string = <<<HEREDOC
   string stuff here
HEREDOC;

The "HEREDOC" part is like the quotes, and can be anything you want. The end tag must be the only thing on it's line i.e. no whitespace before or after, and must end in a colon. For more info check out the manual.

In Tomcat 7, you can use "aliases" property. From the docs:

This attribute provides a list of external locations from which to load resources for this context. The list of aliases should be of the form "/aliasPath1=docBase1,/aliasPath2=docBase2" where aliasPathN must include a leading '/' and docBaseN must be an absolute path to either a .war file or a directory. A resource will be searched for in the first docBaseN for which aliasPathN is a leading path segment of the resource. If there is no such alias, then the resource will be searched in the usual way. These external locations will not be emptied if the context is un-deployed.

I would use javascript for this.

var txtFile = new XMLHttpRequest();
txtFile.open("GET", "http://my.remote.url/myremotefile.txt", true);
txtFile.onreadystatechange = function() {
  if (txtFile.readyState === 4 && txtFile.status == 200) {
     allText = txtFile.responseText;
  }
document.getElementById('your div id').innerHTML = allText;

This is just a code sample, would need tweaking for all browsers, etc.

For Windows, first install the git base from here: https://git-scm.com/downloads

Next, set the environment variable:

1. Press Windows+R and type sysdm.cpl
2. Select advance -> Environment variable
3. Select path-> edit the path and paste the below line:

C:\Program Files\Git\git-bash.exe

To test it, open the command window: press Windows+R, type cmd and then type ssh.

Warning: open_basedir restriction in effect

This warning can appear with various functions that are related to file and directory access. It warns about a configuration issue.

When it appears, it means that access has been forbidden to some files.

The warning itself does not break anything, but most often a script does not properly work if file-access is prevented.

The fix is normally to change the PHP configuration, the related setting is called open_basedir.

Sometimes the wrong file or directory names are used, the fix is then to use the right ones.

Related Questions:

fig, ax = plt.subplots()
for color in ['red', 'green', 'blue']:
    n = 750
    x, y = rand(2, n)
    scale = 200.0 * rand(n)
    ax.scatter(x, y, c=color, s=scale, label=color,

Step 1: Add the submodule

   git submodule add git://some_repository.git some_repository

Step 2: Fix the submodule to a particular commit

By default the new submodule will be tracking HEAD of the master branch, but it will NOT be updated as you update your primary repository. In order to change the submodule to track a particular commit or different branch, change directory to the submodule folder and switch branches just like you would in a normal repository.

   git checkout -b some_branch origin/some_branch

Now the submodule is fixed on the development branch instead of HEAD of master.

You can add folder (say WEB with sub folders css, img and js and file test.html) to your project by choosing Add Files to "MyProj" and selecting Create folder references. Now the following code will take care about all the referred images, css and javascript

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"WEB/test.html" ofType:nil];
[webView  loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePath]]];

.*

. is any char, * means repeated zero or more times.

// This is wrong 
categoryTitle.textColor = [UIColor colorWithRed:188 green:149 blue:88 alpha:1.0];

// This should be  
categoryTitle.textColor = [UIColor colorWithRed:188/255 green:149/255 blue:88/255 alpha:1.0];

// In the documentation, the limit of the parameters are mentioned.

You can try to use:

where(date: p[:date]..Float::INFINITY)

equivalent in sql

WHERE (`date` >= p[:date])

The result is:

Note.where(user_id: current_user.id, notetype: p[:note_type], date: p[:date]..Float::INFINITY).order(:fecha, :created_at)

And I have changed too

order('date ASC, created_at ASC')

For

order(:fecha, :created_at)

The spirit of the question, I think, was not truly answered. No, you cannot use a video tag to play rtsp streams as of now. The other answer regarding the link to Chromium guy's "never" is a bit misleading as the linked thread / answer is not directly referring to Chrome playing rtsp via the video tag. Read the entire linked thread, especially the comments at the very bottom and links to other threads.

The real answer is this: No, you cannot just put a video tag on an html 5 page and play rtsp. You need to use a Javascript library of some sort (unless you want to get into playing things with flash and silverlight players) to play streaming video. {IMHO} At the rate the html 5 video discussion and implementation is going, the various vendors of proprietary video standards are not interested in helping this move forward so don't count of the promised ease of use of the video tag unless the browser makers take it upon themselves to somehow solve the problem...again, not likely.{/IMHO}

Try HostingEnvironment.MapPath, which is static.

See this SO question for confirmation that HostingEnvironment.MapPath returns the same value as Server.MapPath: What is the difference between Server.MapPath and HostingEnvironment.MapPath?

When you call notify() from an object t, java notifies a particular t.wait() method. But, how does java search and notify a particular wait method.

java only looks into the synchronized block of code which was locked by object t. java cannot search the whole code to notify a particular t.wait().

The switch doesn't appear to be case sensitive in PowerShell 5.1. All four of the $someString examples below work.

$someString = "YES"
$someString = "yes"
$someString = "yEs"
$someString = "y"

switch ($someString) {
   {"y","yes"} { "You entered Yes." }
   Default { "You didn't enter Yes."}
}

Here is my $PSVersionTable data.

Swift 5 & String Response, In presentable format

public static func secondsToHoursMinutesSecondsStr (seconds : Int) -> String {
      let (hours, minutes, seconds) = secondsToHoursMinutesSeconds(seconds: seconds);
      var str = hours > 0 ? "\(hours) h" : ""
      str = minutes > 0 ? str + " \(minutes) min" : str
      str = seconds > 0 ? str + " \(seconds) sec" : str
      return str
  }

public static func secondsToHoursMinutesSeconds (seconds : Int) -> (Int, Int, Int) {
        return (seconds / 3600, (seconds % 3600) / 60, (seconds % 3600) % 60)
 }

Usage:

print(secondsToHoursMinutesSecondsStr(seconds: 20000)) // Result = "5 h 33 min 20 sec"

I encountered this same error: ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ', completed)' at line 1

This was the input I had entered on terminal: mysql> create table todos (description, completed);

Solution: For each column type you must specify the type of content they will contain. This could either be text, integer, variable, boolean there are many different types of data.

mysql> create table todos (description text, completed boolean);

Query OK, 0 rows affected (0.02 sec)

It now passed successfully.

Now I solved this issue in this way,

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.io.OutputStream; 

// Create a trust manager that does not validate certificate chains like the default 

TrustManager[] trustAllCerts = new TrustManager[]{
        new X509TrustManager() {

            public java.security.cert.X509Certificate[] getAcceptedIssuers()
            {
                return null;
            }
            public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType)
            {
                //No need to implement.
            }
            public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType)
            {
                //No need to implement.
            }
        }
};

// Install the all-trusting trust manager
try 
{
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} 
catch (Exception e) 
{
    System.out.println(e);
}

Of course this solution should only be used in scenarios, where it is not possible to install the required certifcates using keytool e.g. local testing with temporary certifcates.

http://en.wikipedia.org/wiki/Division_by_zero

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

I was able to solve that problem by adding this to my controller method:

    $title = 'My Title Here';
    View::share('title', $title);

$this->layout->title = 'Home page'; did not work either.
