I think several of the answers hit around the possible solution to your problem.

I agree the easiest (and best solution for SEO purposes) is the 301 redirect. In IIS this is fairly trivial, you'd create a site for subdomain.hostone.com, after creating the site, right-click on the site and go into properties. Click on the "Home Directory" tab of the site properties window that opens. Select the radio button "A redirection to a URL", enter the url for the new site (http://subdomain.hosttwo.com), and check the checkboxes for "The exact URL entered above", "A permanent redirection for this resource" (this second checkbox causes a 301 redirect, instead of a 302 redirect). Click OK, and you're done.

Or you could create a page on the site of http://subdomain.hostone.com, using one of the following methods (depending on what the hosting platform supports)

PHP Redirect:

<?
Header( "HTTP/1.1 301 Moved Permanently" ); 
Header( "Location: http://subdomain.hosttwo.com" ); 
?>

ASP Redirect:

<%@ Language=VBScript %>
<%
Response.Status="301 Moved Permanently"
Response.AddHeader "Location","http://subdomain.hosttwo.com"
%>

ASP .NET Redirect:

<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location","http://subdomain.hosttwo.com");
}
</script>

Now assuming your CNAME record is correctly created, then the only problem you are experiencing is that the site created for http://subdomain.hosttwo.com is using a shared IP, and host headers to determine which site should be displayed. To resolve this issue under IIS, in IIS Manager on the web server, you'd right-click on the site for subdomain.hosttwo.com, and click "Properties". On the displayed "Web Site" tab, you should see an "Advanced" button next to the IP address that you'll need to click. On the "Advanced Web Site Identification" window that appears, click "Add". Select the same IP address that is already being used by subdomain.hosttwo.com, enter 80 as the TCP port, and then enter subdomain.hosttwo.com as the Host Header value. Click OK until you are back to the main IIS Manager window, and you should be good to go. Open a browser, and browse to http://subdomain.hostone.com, and you'll see the site at http://subdomain.hosttwo.com appear, even though your URL shows http://subdomain.hostone.com

Hope that helps...

You should be able to find your command with a ps variant like:

ps -ef
ps -fubob # if your job's user ID is bob.

Then, once located, it should be a simple matter to use kill to kill the process (permissions permitting).

If you're talking about getting rid of jobs in the at queue (that aren't running yet), you can use atq to list them and atrm to get rid of them.

It is basically a header file that also includes every standard library and STL include file. The only purpose I can see for it would be for testing and education.

Se e.g. GCC 4.8.0 /bits/stdc++.h source.

Using it would include a lot of unnecessary stuff and increases compilation time.

Edit: As Neil says, it's an implementation for precompiled headers. If you set it up for precompilation correctly it could, in fact, speed up compilation time depending on your project. (https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html)

I would, however, suggest that you take time to learn about each of the sl/stl headers and include them separately instead, and not use "super headers" except for precompilation purposes.

Well, if, for the repository name you mean the Git root directory name (the one that contains the .git directory) you can run this:

basename `git rev-parse --show-toplevel`

The git rev-parse --show-toplevel part gives you the path to that directory and basename strips the first part of the path.

The best way around this is (and many other situations) in my experience, is to use cntlm which is a local no-authentication proxy which points to a remote authentication proxy. You can then just set WinHTTP to point to your local CNTLM (usually localhost:3128), and you can set CNTLM itself to point to the remote authentication proxy. CNTLM has a "magic NTLM dialect detection" option which generates password hashes to be put into the CNTLM configuration files.

mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/… to get it rewritten to a corresponding /folder1/….

Try this:

RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1

This rule will rewrite every request that starts with the URI path /apple/… internally to /folder1/….

Edit    As you are actually looking for the other way round:

RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]

This rule is designed to work together with the other rule above. Requests of /folder1/… will be redirected externally to /apple/… and requests of /apple/… will then be rewritten internally back to /folder1/….

EcmaScript 2017 introduced Object.entries that allows you to iterate over values and keys. Documentation

var map = { key1 : 'value1', key2 : 'value2' }

for (let [key, value] of Object.entries(map)) {
    console.log(`${key}: ${value}`);
}

The result will be:

key1: value1
key2: value2

No need to update gradle for making release application in Android studio.If you were eclipse user then it will be so easy for you. If you are new then follow the steps

1: Go to the "Build" at the toolbar section. 2: Choose "Generate Signed APK..." option.

3:fill opened form and go next 4 :if you already have .keystore or .jks then choose that file enter your password and alias name and respective password. 5: Or don't have .keystore or .jks file then click on Create new... button as shown on pic 1 then fill the form.

Above process was to make build manually. If You want android studio to automatically Signing Your App

In Android Studio, you can configure your project to sign your release APK automatically during the build process:

On the project browser, right click on your app and select Open Module Settings. On the Project Structure window, select your app's module under Modules. Click on the Signing tab. Select your keystore file, enter a name for this signing configuration (as you may create more than one), and enter the required information. Figure 4. Create a signing configuration in Android Studio.

Click on the Build Types tab. Select the release build. Under Signing Config, select the signing configuration you just created. Figure 5. Select a signing configuration in Android Studio.

4:Most Important thing that make debuggable=false at gradle.

    buildTypes {
        release {
           minifyEnabled false
          proguardFiles getDefaultProguardFile('proguard-  android.txt'), 'proguard-rules.txt'
        debuggable false
        jniDebuggable false
        renderscriptDebuggable false
        zipAlignEnabled true
       }
     }

Step 1:

Locate phpMyAdmin installation path.

Step 2:

Open phpMyAdmin/config.inc.php in your favourite text editor. Copy config.sample.inc.php to config.inc.php if it's missing.

Step 3:

Search for $cfg['Servers'][$i]['auth_type'] = 'config';

Replace it with $cfg['Servers'][$i]['auth_type'] = 'cookie';

Simply define a function and set the value of your Combobox to empty/null or whatever you want. Try the following.

def Reset():
    cmb.set("")

here, cmb is a variable in which you have assigned the Combobox. Now call that function in a button such as,

btn2 = ttk.Button(root, text="Reset",command=Reset)

Will this answer Help you?
If you are receiving the following message in the EventViewer

The Module DLL aspnetcorev2.dll failed to load. The data is the error.

Then yes this will solve your problem

To check your event Viewer

1. press Win+R and type: eventvwr, then press ENTER.
2. On the left side of Windows Event Viewer click on Windows Logs -> Application.
3. Now you need to find some ERRORS for source IIS-W3SVC-WP in the middle window.

Install Microsoft Visual C++ 2015 Redistributable 86x AND 64X (both of them)

You need a regular expression like "\\s+", which means: split whenever at least one whitespace is encountered. The full Java code is:

try {
    String[] splitArray = input.split("\\s+");
} catch (PatternSyntaxException ex) {
    // 
}

Have you tried using the concat() function?

ON tableTwo.query = concat('category_id=',tableOne.category_id)

Use the pause command and enter the number of milliseconds in the Target field.

Set speed to fastest (Actions --> Fastest), otherwise it won't work.

Not sure why no one mentioned to just use the built-in sticky header style for elements. Worked great for me.

.tableContainerDiv {
   overflow: auto;
   max-height: 80em;
}
th {
   position: sticky;
   top: 0;
   background: white;
}

Put a min-width on the in @media if you need to make responsive (or similar).

see Table headers position:sticky or Position Sticky and Table Headers

From my understanding of the code provided above, it loads the file and does map operation and saves it back. There is no operation that requires shuffle. Also, there is no operation that requires data to be brought to the driver hence tuning anything related to shuffle or driver may have no impact. The driver does have issues when there are too many tasks but this was only till spark 2.0.2 version. There can be two things which are going wrong.

• There are only one or a few executors. Increase the number of executors so that they can be allocated to different slaves. If you are using yarn need to change num-executors config or if you are using spark standalone then need to tune num cores per executor and spark max cores conf. In standalone num executors = max cores / cores per executor .
• The number of partitions are very few or maybe only one. So if this is low even if we have multi-cores,multi executors it will not be of much help as parallelization is dependent on the number of partitions. So increase the partitions by doing imageBundleRDD.repartition(11)

If you combine the answers above, finally a pom.xml that configured for UTF-8 should seem like that.

JSFiddle with your code, works :)

'Command + M' for OSX is working for me.

Use: nm --demangle <libname>.so

the below command works for me:

psql -d myDb -U username -W

In my case I was hosting with GoDaddy which wasn't the problem but it added a layer of confusion.

I had a root folder "WebServices" and set that as the application root.

HOWEVER the service was in a subfolder called "GeoLocateSpecials" as the "WebServices" folder is a container for many services.

So I had to set GeoLocateSpecials as an application root and it worked great from there.

Hope that helps anyone else out there.

Simple way to access the Url Try this Code

 $.ajax({
     type: "POST",
      url: '/Controller/Search', 
     data: "{queryString:'" + searchVal + "'}",
     contentType: "application/json; charset=utf-8",
     dataType: "html",
     success: function (data) {
     alert("here" + data.d.toString());
    });

Just remove the white space from the string before you split it.

mylist = my_string.replace(' ','').split(',')

Adding context to hopefully help provide a bit of additional clarity on this subject. To a BaSH newbie, it's sense of true/false statements is rather odd. Take the following simple examples and their results.

This statement will return "true":

foo=" "; if [ "$foo" ]; then echo "true"; else echo "false"; fi

But this will return "false":

foo=" "; if [ $foo ]; then echo "true"; else echo "false"; fi

Do you see why? The first example has a quoted "" string. This causes BaSH to treat it literally. So, in a literal sense, a space is not null. While in a non-literal sense (the 2nd example above), a space is viewed by BaSH (as a value in $foo) as 'nothing' and therefore it equates to null (interpreted here as 'false').

These statements will all return a text string of "false":

foo=; if [ $foo ]; then echo "true"; else echo "false"; fi
foo=; if [ "$foo" ]; then echo "true"; else echo "false"; fi
foo=""; if [ $foo ]; then echo "true"; else echo "false"; fi
foo=""; if [ "$foo" ]; then echo "true"; else echo "false"; fi

Interestingly, this type of conditional will always return true:

These statements will all return a result of "true":

foo=""; if [ foo ]; then echo "true"; else echo "false"; fi

Notice the difference; the $ symbol has been omitted from preceding the variable name in the conditional. It doesn't matter what word you insert between the brackets. BaSH will always see this statement as true, even if you use a word that has never been associated with a variable in the same shell before.

if [ sooperduper ]; then echo "true"; else echo "false"; fi

Likewise, defining it as an undeclared variable ensures it will always return false:

if [ $sooperduper ]; then echo "true"; else echo "false"; fi

As to BaSH it's the same as writing:

sooperduper="";if [ $sooperduper ]; then echo "true"; else echo "false"; fi

One more tip....

Brackets vs No Brackets

Making matters more confusing, these variations on the IF/THEN conditional both work, but return opposite results.

These return false:

if [ $foo ]; then echo "true"; else echo "false"; fi
if [ ! foo ]; then echo "true"; else echo "false"; fi

However, these will return a result of true:

if $foo; then echo "true"; else echo "false"; fi
if [ foo ]; then echo "true"; else echo "false"; fi
if [ ! $foo ]; then echo "true"; else echo "false"; fi

And, of course this returns a syntax error (along with a result of 'false'):

if foo; then echo "true"; else echo "false"; fi

Confused yet? It can be quite challenging to keep it straight in your head in the beginning, especially if you're used to other, higher level programming languages.

If you are using server side code like Java then you need to return active tab name and on return page have some function to disable( meaning remove active class) all tabs except the one you returned.

This would require you to add id or name to each tab. Little bit more work :)

If anyone else comes across this and the accepted answer doesn't work (it didn't for me), check to see if you need to specify a port other than 80. In my case, I was running a rails server at localhost:3000 and was just using curl http://localhost, which was hitting port 80.

Changing the command to curl http://localhost:3000 is what worked in my case.

May be easier using a java.util.HashSet. For example:

  List <String> list = new ArrayList<String>(); 
  list.add("behold");
  list.add("bend");
  list.add("bet");

  //Load the list into a hashSet
  Set<String> set = new HashSet<String>(list);
  if (set.contains("bend"))
  {
    System.out.println("String found!");
  }

Check it's value property:

In jQuery (since your tag mentions it):

$('#fileInput').val()

Or in vanilla JavaScript:

document.getElementById('myFileInput').value

You may simply use both as per the specification kindly provided by Oli.

I always use border:0 none;.

Though there is no harm in specifying them seperately and some browsers will parse the CSS faster if you do use the legacy CSS1 property calls.

Though border:0; will normally default the border style to none, I have however noticed some browsers enforcing their default border style which can strangely overwrite border:0;.

Try remove_missing instead with vars = the_variable. It is very important that you set the vars argument, otherwise remove_missing will remove all rows that contain an NA in any column!! Setting na.rm = TRUE will suppress the warning message.

ggplot(data = remove_missing(MyData, na.rm = TRUE, vars = the_variable),aes(x= the_variable, fill=the_variable, na.rm = TRUE)) + 
       geom_bar(stat="bin") 

If you tried profiling, and then it didn't work, and now you cannot build, go into your Target pane (via the Project Icon), Switch to the Build Settings tab, search for PROFILE - and set CLANG_USE_OPTIMIZATION_PROFILE to "No".

You can turn the color picker into an application by following the guide here:

http://hints.macworld.com/article.php?story=20060408050920158

From the guide:

Simply fire up AppleScript (Applications -> AppleScript Editor) and enter this text:

choose color

Now, save it as an application (File -> Save As, and set the File Format pop-up to Application), and you're done

It far easier to use the scripting runtime which is installed by default on Windows

Just go project Reference and check Microsoft Scripting Runtime and click OK.

Then you can use this code which is way better than the default file commands

Dim FSO As FileSystemObject
Dim TS As TextStream
Dim TempS As String
Dim Final As String
Set FSO = New FileSystemObject
Set TS = FSO.OpenTextFile("C:\Clients\Converter\Clockings.mis", ForReading)
'Use this for reading everything in one shot
Final = TS.ReadAll
'OR use this if you need to process each line
Do Until TS.AtEndOfStream
    TempS = TS.ReadLine
    Final = Final & TempS & vbCrLf
Loop
TS.Close

Set TS = FSO.OpenTextFile("C:\Clients\Converter\2.txt", ForWriting, True)
    TS.Write Final
TS.Close
Set TS = Nothing
Set FSO = Nothing

As for what is wrong with your original code here you are reading each line of the text file.

Input #iFileNo, sFileText

Then here you write it out

Write #iFileNo, sFileText

sFileText is a string variable so what is happening is that each time you read, you just replace the content of sFileText with the content of the line you just read.

So when you go to write it out, all you are writing is the last line you read, which is probably a blank line.

Dim sFileText As String
Dim sFinal as String
Dim iFileNo As Integer
iFileNo = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iFileNo
Do While Not EOF(iFileNo)
  Input #iFileNo, sFileText
sFinal = sFinal & sFileText & vbCRLF
Loop
Close #iFileNo

iFileNo = FreeFile 'Don't assume the last file number is free to use
Open "C:\Clients\Converter\2.txt" For Output As #iFileNo
Write #iFileNo, sFinal
Close #iFileNo

Note you don't need to do a loop to write. sFinal contains the complete text of the File ready to be written at one shot. Note that input reads a LINE at a time so each line appended to sFinal needs to have a CR and LF appended at the end to be written out correctly on a MS Windows system. Other operating system may just need a LF (Chr$(10)).

If you need to process the incoming data then you need to do something like this.

Dim sFileText As String
Dim sFinal as String
Dim vTemp as Variant
Dim iFileNo As Integer
Dim C as Collection
Dim R as Collection
Dim I as Long
Set C = New Collection
Set R = New Collection

iFileNo = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iFileNo
Do While Not EOF(iFileNo)
  Input #iFileNo, sFileText
  C.Add sFileText
Loop
Close #iFileNo

For Each vTemp in C
     Process vTemp
Next sTemp

iFileNo = FreeFile
Open "C:\Clients\Converter\2.txt" For Output As #iFileNo
For Each vTemp in R
   Write #iFileNo, vTemp & vbCRLF
Next sTemp
Close #iFileNo

When you want to read a file with a different configuration than the default one, feel free to use either mpu.aws.s3_read(s3path) directly or the copy-pasted code:

Most of the time you will have to install both x86 and x64 !

Links here: x86 and x64

They are the Visual C++ 2010 SP1 Redistributable Package

(it happened to me when installing MySQL Workbench)

$(document).ready(function(){
    $('input.checkD[type="checkbox"]').click(function(){
        if($(this).prop("checked") == true){
            $(this).val('true');
        }
        else if($(this).prop("checked") == false){
            $(this).val('false');
        }
    });
});

Java doesn't (yet) have a good built-in Time class (it has one for JDBC queries, but that's not what you want).

One option would be use the JodaTime APIs and its LocalTime class.

Sticking with just the built-in Java APIs, you are stuck with java.util.Date. You can use a SimpleDateFormat to parse the time, then the Date comparison functions to see if it is before or after some other time:

SimpleDateFormat parser = new SimpleDateFormat("HH:mm");
Date ten = parser.parse("10:00");
Date eighteen = parser.parse("18:00");

try {
    Date userDate = parser.parse(someOtherDate);
    if (userDate.after(ten) && userDate.before(eighteen)) {
        ...
    }
} catch (ParseException e) {
    // Invalid date was entered
}

Or you could just use some string manipulations, perhaps a regular expression to extract just the hour and the minute portions, convert them to numbers and do a numerical comparison:

Pattern p = Pattern.compile("(\d{2}):(\d{2})");
Matcher m = p.matcher(userString);
if (m.matches() ) {
    String hourString = m.group(1);
    String minuteString = m.group(2);
    int hour = Integer.parseInt(hourString);
    int minute = Integer.parseInt(minuteString);

    if (hour >= 10 && hour <= 18) {
        ...
    }
}

It really all depends on what you are trying to accomplish.

You can create .war file back from your existing folder.

Using this command

cd /to/your/folder/location
jar -cvf my_web_app.war *

It looks like the machine you're trying to run this on has only 256 MB memory.

Maybe the JVM tries to allocate a large, contiguous block of 64 MB memory. The 192 MB that you have free might be fragmented into smaller pieces, so that there is no contiguous block of 64 MB free to allocate.

Try starting your Java program with a smaller heap size, for example:

java -Xms16m ...

I saw this with a specific Zip-file with Java 6, but it went away when I upgrade to Java 8 (did not test Java 7), so it seems newer versions of ZipFile in Java support more compression algorithms and thus can read files which fail with earlier versions.

So you need to use what we call promise. Read how angular handles it here, https://docs.angularjs.org/api/ng/service/$q. Turns our $http support promises inherently so in your case we'll do something like this,

(function() {
  "use strict";
  var serviceCallJson = function($http) {

      this.getCustomers = function() {
        // http method anyways returns promise so you can catch it in calling function
        return $http({
            method : 'get',
            url : '../viewersData/userPwdPair.json'
          });
      }

  }

  var validateIn = function (serviceCallJson, $q) {

      this.called = function(username, password) {
          var deferred = $q.defer(); 
          serviceCallJson.getCustomers().then( 
            function( returnedData ) {
              console.log(returnedData); // you should get output here this is a success handler
              var i = 0;
              angular.forEach(returnedData, function(value, key){
                while (i < 10) {
                  if(value[i].username == username) {
                    if(value[i].password == password) {
                     alert("Logged In");
                    }
                  }
                  i = i + 1;
                }
              });
            }, 
            function() {

              // this is error handler
            } 
          );
          return deferred.promise;  
      }

  }

  angular.module('assignment1App')
    .service ('serviceCallJson', serviceCallJson)

  angular.module('assignment1App')
  .service ('validateIn', ['serviceCallJson', validateIn])

}())

Create a .env file that will hold your credentials at the root of your project and leave it out of versioning:

$ echo ".env" >> .gitignore

In the .env file, add the variables (adapt them according to your installation):

$ echo "DJANGO_SETTINGS_MODULE=myproject.settings.production"> .env
#50 caracter random key
$ echo "SECRET_KEY='####'">> .env

To use them, put this on top of your production.py settings file:

import os

env = os.environ.copy()
SECRET_KEY = env['SECRET_KEY']

Publish it to Heroku using this gem: http://github.com/ddollar/heroku-config.git

$ heroku plugins:install git://github.com/ddollar/heroku-config.git
$ heroku config:push

This way you avoid to change virtualenv files.

*Based on this tutorial

If you are going to use this conversion a lot, consider calculating once and putting the results in a dictionary:

>>> import string
>>> di=dict(zip(string.letters,[ord(c)%32 for c in string.letters]))
>>> di['c'] 
3

The advantage is dictionary lookups are very fast vs iterating over a list on every call.

>>> for c in sorted(di.keys()):
>>>    print "{0}:{1}  ".format(c, di[c])
# what you would expect....

It's quite easy. Just write this, for example:

npm install -g [email protected]

Or:

npm install -g npm@latest    // For the last stable version
npm install -g npm@next      // For the most recent release

As dasblinkenlight already answered, the numbers come from the way that floating point numbers are represented in IEEE-754, and Andreas has a nice breakdown of the maths.

However - be careful that the precision of floating point numbers isn't exactly 6 or 15 significant decimal digits as the table suggests, since the precision of IEEE-754 numbers depends on the number of significant binary digits.

• float has 24 significant binary digits - which depending on the number represented translates to 6-8 decimal digits of precision.

• double has 53 significant binary digits, which is approximately 15 decimal digits.

Another answer of mine has further explanation if you're interested.

If you can't use a public/private keys, you can use expect:

#!/usr/bin/expect
spawn rsync SRC DEST
expect "password:"
send "PASS\n"
expect eof
if [catch wait] {
    puts "rsync failed"
    exit 1
}
exit 0

You will need to replace SRC and DEST with your normal rsync source and destination parameters, and replace PASS with your password. Just make sure this file is stored securely!

You should not put an ondelete field against a cascade in the database.

So set the onDelete field to RESTRICT

Good luck ?

you should install a x server such as XMing. and keep the x server is running. config your putty like this :Connection-Data-SSH-X11-Enable X11 forwarding should be checked. and X display location : localhost:0

net stop <your service> && net start <your service>

No net restart, unfortunately.

With Termsql you can do it in one line:

termsql -i mycsvfile.CSV -d ',' -c 'a,b' -t 'foo' -o mynewdatabase.db

That seems to work for me:

<html>
<head><style>
#monkey {color:blue}
#ape {color:purple}
</style></head>
<body>
<span id="monkey" onclick="changeid()">
fruit
</span>
<script>
function changeid ()
{
var e = document.getElementById("monkey");
e.id = "ape";
}
</script>
</body>
</html>

The expected behaviour is to change the colour of the word "fruit".

Perhaps your document was not fully loaded when you called the routine?

The Babel docs describe this pretty concisely:

Babel includes a polyfill that includes a custom regenerator runtime and core.js.

This will emulate a full ES6 environment. This polyfill is automatically loaded when using babel-node and babel/register.

Make sure you require it at the entry-point to your application, before anything else is called. If you're using a tool like webpack, that becomes pretty simple (you can tell webpack to include it in the bundle).

If you're using a tool like gulp-babel or babel-loader, you need to also install the babel package itself to use the polyfill.

Also note that for modules that affect the global scope (polyfills and the like), you can use a terse import to avoid having unused variables in your module:

import 'babel/polyfill';

You can specify the constraints and defaults in a CREATE TABLE AS SELECT, but the syntax is as follows

create table t1 (id number default 1 not null);
insert into t1 (id) values (2);

create table t2 (id default 1 not null)
as select * from t1;

That is, it won't inherit the constraints from the source table/select. Only the data type (length/precision/scale) is determined by the select.

I don't think there's anything wrong with either solutions you proposed in your question.

In my own code, I would implement it like this though:

(x for x in seq if predicate(x)).next()

The syntax with () creates a generator, which is more efficient than generating all the list at once with [].

This location has, once again, changed, if using Swift, use this to find out where the folder is (this is copied from the AppDelegate.swift file that Apple creates for you so if it doesn't work on your machine, search in that file for the right syntax, this works on mine using Xcode 6.1 and iOS 8 simulator):

let urls = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
println("Possible sqlite file: \(urls)")

Having to go to the parent node first seems a bit odd to me, is there a reason JavaScript works like this?

IMHO: The reason for this is the same as I've seen in other environments: You are performing an action based on your "link" to something. You can't delete it while you're linked to it.

Like cutting a tree limb. Sit on the side closest to the tree while cutting or the result will be ... unfortunate (although funny).

As well as find listed in other answers, better shells allow both recurvsive globs and filtering of glob matches, so in zsh for example...

ls -lad **/*(/)

...lists all directories while keeping all the "-l" details that you want, which you'd otherwise need to recreate using something like...

find . -type d -exec ls -ld {} \;

(not quite as easy as the other answers suggest)

The benefit of find is that it's more independent of the shell - more portable, even for system() calls from within a C/C++ program etc..

Redirect PHP time programming:

 <?php
 header("Refresh:10;url=***-----índex.php--OR----URL-----");
 ?>

On Windows, you can run the systeminfo command and retrieves its output for instance with the following code:

private static class WindowsSystemInformation
{
    static String get() throws IOException
    {
        Runtime runtime = Runtime.getRuntime();
        Process process = runtime.exec("systeminfo");
        BufferedReader systemInformationReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

        StringBuilder stringBuilder = new StringBuilder();
        String line;

        while ((line = systemInformationReader.readLine()) != null)
        {
            stringBuilder.append(line);
            stringBuilder.append(System.lineSeparator());
        }

        return stringBuilder.toString().trim();
    }
}

My Final Approach:

    public void PutObject(string postUrl, object payload)
        {
            var request = (HttpWebRequest)WebRequest.Create(postUrl);
            request.Method = "PUT";
            request.ContentType = "application/xml";
            if (payload !=null)
            {
                request.ContentLength = Size(payload);
                Stream dataStream = request.GetRequestStream();
                Serialize(dataStream,payload);
                dataStream.Close();
            }

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            string returnString = response.StatusCode.ToString();
        }

public void Serialize(Stream output, object input)
            {
                var ser = new DataContractSerializer(input.GetType());
                ser.WriteObject(output, input);
            }

Not familiar with DateTime...

If you have two Dates you can call getTime on them to get millseconds, get the diff and divide by 1000. For example

Date d1 = ...;
Date d2 = ...;
long seconds = (d2.getTime()-d1.getTime())/1000;

If you have Calendar objects you can call

c.getTimeInMillis()

and do the same

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

Have a look at my primer on exactly this topic.

UPDATE:

var sio = require('socket.io'),
    app = require('express').createServer();

app.listen(8080);
sio = sio.listen(app);

sio.on('connection', function (client) {
  console.log('client connected');

  // send the clients id to the client itself.
  client.send(client.id);

  client.on('disconnect', function () {
    console.log('client disconnected');
  });
});

The basic answer is to accumulate the sum of both x (call it 'sum_x1') and x² (call it 'sum_x2') as you go. The value of the standard deviation is then:

stdev = sqrt((sum_x2 / n) - (mean * mean)) 

where

mean = sum_x / n

This is the sample standard deviation; you get the population standard deviation using 'n' instead of 'n - 1' as the divisor.

You may need to worry about the numerical stability of taking the difference between two large numbers if you are dealing with large samples. Go to the external references in other answers (Wikipedia, etc) for more information.

If you have the database with a front end and a back end. You can use the following code on the main form of your front end main navigation form:

Dim sDataFile As String, sDataFileTemp As String, sDataFileBackup As String
Dim s1 As Long, s2 As Long

sDataFile = "C:\MyDataFile.mdb"
sDataFileTemp = "C:\MyDataFileTemp.mdb"
sDataFileBackup = "C:\MyDataFile Backup " & Format(Now, "YYYY-MM-DD HHMMSS") & ".mdb"

DoCmd.Hourglass True

'get file size before compact
Open sDataFile For Binary As #1
s1 = LOF(1)
Close #1

'backup data file
FileCopy sDataFile, sDataFileBackup

'only proceed if data file exists
If Dir(sDataFileBackup vbNormal) <> "" Then

        'compact data file to temp file
        On Error Resume Next
        Kill sDataFileTemp
        On Error GoTo 0
        DBEngine.CompactDatabase sDataFile, sDataFileTemp

        If Dir(sDataFileTemp, vbNormal) <> "" Then
            'delete old data file data file
            Kill sDataFile

            'copy temp file to data file
            FileCopy sDataFileTemp, sDataFile

            'get file size after compact
            Open sDataFile For Binary As #1
            s2 = LOF(1)
            Close #1

            DoCmd.Hourglass False
            MsgBox "Compact complete " & vbCrLf & vbCrLf _
                & "Size before: " & Round(s1 / 1024 / 1024, 2) & "Mb" & vbCrLf _
                & "Size after:    " & Round(s2 / 1024 / 1024, 2) & "Mb", vbInformation
        Else
            DoCmd.Hourglass False
            MsgBox "ERROR: Unable to compact data file"
        End If

Else
        DoCmd.Hourglass False
        MsgBox "ERROR: Unable to backup data file"
End If

First, if you have already run the migrations generated by the scaffold command, you have to perform a rollback first.

rake db:rollback

You can create scaffolding using:

rails generate scaffold MyFoo 

(or similar), and you can destroy/undo it using

rails destroy scaffold MyFoo

That will delete all the files created by generate, but not any additional changes you may have made manually.

For array of multiple arrays and ES6, use

Array.prototype.concat(...arr);

For example:

const arr = [[1, 2, 3], [4, 5, 6], [7, 8 ,9]];
const newArr = Array.prototype.concat(...arr);
// output: [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]

Here is one case that caught me out, using a global as a default value of a parameter.

globVar = None    # initialize value of global variable

def func(param = globVar):   # use globVar as default value for param
    print 'param =', param, 'globVar =', globVar  # display values

def test():
    global globVar
    globVar = 42  # change value of global
    func()

test()
=========
output: param = None, globVar = 42

I had expected param to have a value of 42. Surprise. Python 2.7 evaluated the value of globVar when it first parsed the function func. Changing the value of globVar did not affect the default value assigned to param. Delaying the evaluation, as in the following, worked as I needed it to.

def func(param = eval('globVar')):       # this seems to work
    print 'param =', param, 'globVar =', globVar  # display values

Or, if you want to be safe,

def func(param = None)):
    if param == None:
        param = globVar
    print 'param =', param, 'globVar =', globVar  # display values

Why such complications?

public static GregorianCalendar convertFromDMY(String dd_mm_yy) throws ParseException 
{
    SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
    Date date = fmt.parse(dd_mm_yy);
    GregorianCalendar cal = GregorianCalendar.getInstance();
    cal.setTime(date);
    return cal;
}

You can make the output just 4 and 24 using unlist:

unlist(gregexpr(pattern ='2',"the2quickbrownfoxeswere2tired"))
[1]  4 24

I couldn't find a single answer or a section in the official Django docs that had all the information I needed to override/extend the default admin templates, so I'm writing this answer as a complete guide, hoping that it would be helpful for others in the future.

Assuming the standard Django project structure:

mysite-container/         # project container directory
    manage.py
    mysite/               # project package
        __init__.py
        admin.py
        apps.py
        settings.py
        urls.py
        wsgi.py
    app1/
    app2/
    ...
    static/
    templates/

Here's what you need to do:

1. In mysite/admin.py, create a sub-class of AdminSite:

   from django.contrib.admin import AdminSite
   
   
   class CustomAdminSite(AdminSite):
       # set values for `site_header`, `site_title`, `index_title` etc.
       site_header = 'Custom Admin Site'
       ...
   
       # extend / override admin views, such as `index()`
       def index(self, request, extra_context=None):
           extra_context = extra_context or {}
   
           # do whatever you want to do and save the values in `extra_context`
           extra_context['world'] = 'Earth'
   
           return super(CustomAdminSite, self).index(request, extra_context)
   
   
   custom_admin_site = CustomAdminSite()
   

   Make sure to import custom_admin_site in the admin.py of your apps and register your models on it to display them on your customized admin site (if you want to).

2. In mysite/apps.py, create a sub-class of AdminConfig and set default_site to admin.CustomAdminSite from the previous step:

   from django.contrib.admin.apps import AdminConfig
   
   
   class CustomAdminConfig(AdminConfig):
       default_site = 'admin.CustomAdminSite'
   

3. In mysite/settings.py, replace django.admin.site in INSTALLED_APPS with apps.CustomAdminConfig (your custom admin app config from the previous step).

4. In mysite/urls.py, replace admin.site.urls from the admin URL to custom_admin_site.urls

   from .admin import custom_admin_site
   
   
   urlpatterns = [
       ...
       path('admin/', custom_admin_site.urls),
       # for Django 1.x versions: url(r'^admin/', include(custom_admin_site.urls)),
       ...
   ]
   

5. Create the template you want to modify in your templates directory, maintaining the default Django admin templates directory structure as specified in the docs. For example, if you were modifying admin/index.html, create the file templates/admin/index.html.

   All of the existing templates can be modified this way, and their names and structures can be found in Django's source code.

6. Now you can either override the template by writing it from scratch or extend it and then override/extend specific blocks.

   For example, if you wanted to keep everything as-is but wanted to override the content block (which on the index page lists the apps and their models that you registered), add the following to templates/admin/index.html:

   {% extends 'admin/index.html' %}
   
   {% block content %}
     <h1>
       Hello, {{ world }}!
     </h1>
   {% endblock %}
   

   To preserve the original contents of a block, add {{ block.super }} wherever you want the original contents to be displayed:

   {% extends 'admin/index.html' %}
   
   {% block content %}
     <h1>
       Hello, {{ world }}!
     </h1>
     {{ block.super }}
   {% endblock %}
   

   You can also add custom styles and scripts by modifying the extrastyle and extrahead blocks.

In case anyone was wondering - it was probably my css...

@font-face
  font-family: "bingo"
  src: url('bingo.eot')
  src: local('bingo')
  src: url('bingo.svg#bingo') format('svg')
  src: url('bingo.otf') format('opentype')

will render as

@font-face {
  font-family: "bingo";
  src: url('bingo.eot');
  src: local('bingo');
  src: url('bingo.svg#bingo') format('svg');
  src: url('bingo.otf') format('opentype'); }

which seems to be close enough... just need to check the SVG rendering

You could make a method:

public byte[] toBytes(char[] data) {
byte[] toRet = new byte[data.length];
for(int i = 0; i < toRet.length; i++) {
toRet[i] = (byte) data[i];
}
return toRet;
}

Hope this helps

When you use JSON stringify then use html_entity_decode first before json_decode.

$tempData = html_entity_decode($tempData);
$cleanData = json_decode($tempData);

I would use an Manifest file to tell (modern) web browsers to also load all relevant images and cache them. Use Grunt and grunt-manifest to do this automatically and never worry again about preload scripts, cache invalidators, CDN etc.

By HTML5 drafts, input type=time creates a control for time of the day input, expected to be implemented using “the user’s preferred presentation”. But this really means using a widget where time presentation follows the rules of the browser’s locale. So independently of the language of the surrounding content, the presentation varies by the language of the browser, the language of the underlying operating system, or the system-wide locale settings (depending on browser). For example, using a Finnish-language version of Chrome, I see the widget as using the standard 24-hour clock. Your mileage will vary.

Thus, input type=time are based on an idea of localization that takes it all out of the hands of the page author. This is intentional; the problem has been raised in HTML5 discussions several times, with the same outcome: no change. (Except possibly added clarifications to the text, making this behavior described as intended.)

Note that pattern and placeholder attributes are not allowed in input type=time. And placeholder="hrs:mins", if it were implemented, would be potentially misleading. It’s quite possible that the user has to type 12.30 (with a period) and not 12:30, when the browser locale uses “.” as a separator in times.

My conclusion is that you should use input type=text, with pattern attribute and with some JavaScript that checks the input for correctness on browsers that do not support the pattern attribute natively.

Here is a solution for transposing a list of lists that is not necessarily square:

maxCol = len(l[0])
for row in l:
    rowLength = len(row)
    if rowLength > maxCol:
        maxCol = rowLength
lTrans = []
for colIndex in range(maxCol):
    lTrans.append([])
    for row in l:
        if colIndex < len(row):
            lTrans[colIndex].append(row[colIndex])

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Not that I know of. But you can configure Firefox to automatically start the download and save the file in a specific place. Your test could then check that the file actually arrived.

Find out two pieces of information

• Whats the hostname or IP of the target ssh server
• What port is the ssh daemon listening on (default is port 22)

$> telnet <hostname or ip> <port>

Assuming the daemon is up and running and listening on that port it should etablish a telnet session. Likely causes:

• The ssh daemon is not running
• The host is blocking the target port with its software firewall
• Some intermediate network device is blocking or filtering the target port
• The ssh daemon is listening on a non standard port
• A TCP wrapper is configured and is filtering out your source host

A callback function in C is the equivalent of a function parameter / variable assigned to be used within another function.Wiki Example

In the code below,

#include <stdio.h>
#include <stdlib.h>

/* The calling function takes a single callback as a parameter. */
void PrintTwoNumbers(int (*numberSource)(void)) {
    printf("%d and %d\n", numberSource(), numberSource());
}

/* A possible callback */
int overNineThousand(void) {
    return (rand() % 1000) + 9001;
}

/* Another possible callback. */
int meaningOfLife(void) {
    return 42;
}

/* Here we call PrintTwoNumbers() with three different callbacks. */
int main(void) {
    PrintTwoNumbers(&rand);
    PrintTwoNumbers(&overNineThousand);
    PrintTwoNumbers(&meaningOfLife);
    return 0;
}

The function (*numberSource) inside the function call PrintTwoNumbers is a function to "call back" / execute from inside PrintTwoNumbers as dictated by the code as it runs.

So if you had something like a pthread function you could assign another function to run inside the loop from its instantiation.

I found an easier solution than I think given by the ones above and easier than rolling your own. I simply created a small rating bar, then added an onTouchListener to it. From there I compute the width of the click and determine the number of stars from that. Having used this several times, the only quirk I've found is that drawing of a small rating bar doesn't always turn out right in a table unless I enclose it in a LinearLayout (looks right in the editor, but not the device). Anyway, in my layout:

            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >
                <RatingBar
                    android:id="@+id/myRatingBar"
                    style="?android:attr/ratingBarStyleSmall"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:numStars="5" />
            </LinearLayout>

and within my activity:

    final RatingBar minimumRating = (RatingBar)findViewById(R.id.myRatingBar);
    minimumRating.setOnTouchListener(new OnTouchListener()
    { 
        public boolean onTouch(View view, MotionEvent event)
        { 
            float touchPositionX = event.getX();
            float width = minimumRating.getWidth();
            float starsf = (touchPositionX / width) * 5.0f;
            int stars = (int)starsf + 1;
            minimumRating.setRating(stars);
            return true; 
        } 
    });

I hope this helps someone else. Definitely easier than drawing one's own (although I've found that also works, but I just wanted an easy use of stars).

Using SVN 1.8, deleting lock file does not help (lock file does not exists).

Refresh/Cleanup did not solve either.

What did solve:

1) Backup your directory, just incase...
2) Team... Disconnect. Choose to remove .svn files
3) Add it again to SVN.

Note: In my case, error was due to loss of network connection during initial commit.

NoneType is simply the type of the None singleton:

>>> type(None)
<type 'NoneType'>

From the latter link above:

None

The sole value of the type NoneType. None is frequently used to represent the absence of a value, as when default arguments are not passed to a function. Assignments to None are illegal and raise a SyntaxError.

In your case, it looks like one of the items you are trying to concatenate is None, hence your error.

Use modulo

whenever a number x is a multiple of some number y, then always x % y equal to 0, which can be used as a check. So use

if (j % 4 == 0) 

I am guessing you are using a 32 bit eclipse with 32 bit JVM. It wont allow heapsize above what you have specified.

Using a 64-bit Eclipse with a 64-bit JVM helps you to start up eclipse with much larger memory. (I am starting with -Xms1024m -Xmx4000m)

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

I have never understand this concept of "git not being good on Windows"; I develop exclusively under Windows and I have never had any problems with git.

I would definitely recommend git over subversion; its simply so much more versatile and allows "offline development" in a way subversion never really could. Its available on almost every platform imaginable and has more features than you'll probably ever use.

Yes, this is described in the documentation. You have to use the InOrder class.

Example (assuming two mocks already created):

InOrder inOrder = inOrder(serviceAMock, serviceBMock);

inOrder.verify(serviceAMock).methodOne();
inOrder.verify(serviceBMock).methodTwo();

select isnull(nullif(CAR_OWNER_TEL, ''), 'NULLLLL')  PHONE from TABLE

will replace CAR_OWNER_TEL if empty by NULLLLL (MS SQL)

I may be late to the party but will have to add my own code for this. It uses approximately n/2 in space because we don't need to store even numbers and I also make use of the bitarray python module, further draStically cutting down on memory consumption and enabling computing all primes up to 1,000,000,000

from bitarray import bitarray
def primes_to(n):
    size = n//2
    sieve = bitarray(size)
    sieve.setall(1)
    limit = int(n**0.5)
    for i in range(1,limit):
        if sieve[i]:
            val = 2*i+1
            sieve[(i+i*val)::val] = 0
    return [2] + [2*i+1 for i, v in enumerate(sieve) if v and i > 0]

python -m timeit -n10 -s "import euler" "euler.primes_to(1000000000)"
10 loops, best of 3: 46.5 sec per loop

This was run on a 64bit 2.4GHZ MAC OSX 10.8.3

I have added the following on my excel sheet

=VLOOKUP(B2,Res_partner!$A$2:$C$21208,1,FALSE)

Still doesn't seem to work. I get an #N/A
BUT

=VLOOKUP(B2,Res_partner!$C$2:$C$21208,1,FALSE)

Works

This is a big topic. The Spring reference doc devotes multiple chapters to it. I recommend reading the ones on Aspect-Oriented Programming and Transactions, as Spring's declarative transaction support uses AOP at its foundation.

But at a very high level, Spring creates proxies for classes that declare @Transactional on the class itself or on members. The proxy is mostly invisible at runtime. It provides a way for Spring to inject behaviors before, after, or around method calls into the object being proxied. Transaction management is just one example of the behaviors that can be hooked in. Security checks are another. And you can provide your own, too, for things like logging. So when you annotate a method with @Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you're annotating. And when clients make calls into your object, the calls are intercepted and the behaviors injected via the proxy mechanism.

Transactions in EJB work similarly, by the way.

As you observed, through, the proxy mechanism only works when calls come in from some external object. When you make an internal call within the object, you're really making a call through the "this" reference, which bypasses the proxy. There are ways of working around that problem, however. I explain one approach in this forum post in which I use a BeanFactoryPostProcessor to inject an instance of the proxy into "self-referencing" classes at runtime. I save this reference to a member variable called "me". Then if I need to make internal calls that require a change in the transaction status of the thread, I direct the call through the proxy (e.g. "me.someMethod()".) The forum post explains in more detail. Note that the BeanFactoryPostProcessor code would be a little different now, as it was written back in the Spring 1.x timeframe. But hopefully it gives you an idea. I have an updated version that I could probably make available.

The correct way of using post variables is

<?php

$department = $_POST['department'];

?>

Use single quotation(')

Another option is to use the built-in Command Palette, which will walk you right through cloning a Git repository to a new directory.

From Using Version Control in VS Code:

You can clone a Git repository with the Git: Clone command in the Command Palette (Windows/Linux: Ctrl + Shift + P, Mac: Command + Shift + P). You will be asked for the URL of the remote repository and the parent directory under which to put the local repository.

At the bottom of Visual Studio Code you'll get status updates to the cloning. Once that's complete an information message will display near the top, allowing you to open the folder that was created.

Note that Visual Studio Code uses your machine's Git installation, and requires 2.0.0 or higher.

I don't have enough rep to comment on Adam's answer, but the best way to do it imo is like this:

public static string RepeatString(string content, int numTimes) {
        if(!string.IsNullOrEmpty(content) && numTimes > 0) {
            StringBuilder builder = new StringBuilder(content.Length * numTimes);

            for(int i = 0; i < numTimes; i++) builder.Append(content);

            return builder.ToString();
        }

        return string.Empty;
    }

You must check to see if numTimes is greater then zero, otherwise you will get an exception.

You can use ansible-vault for using secret keys in playbooks. Define your password in yml.

ex. pass: secret or

user:
  pass: secret
  name: fake

encrypt your secrets file with :

ansible-vault encrypt /path/to/credential.yml

ansible will ask a password for encrypt it. (i will explain how to use that pass)

And then you can use your variables where you want. No one can read them without vault-key.

Vault key usage:

via passing argument when running playbook.

--ask-vault-pass: secret

or you can save into file like password.txt and hide somewhere. (useful for CI users)

--vault-password-file=/path/to/file.txt

In your case : include vars yml and use your variables.

- include_vars: /path/credential.yml

  - name: Add deployment user
    action: user name={{user.name}} password={{user.pass}}

I think what you are trying to achieve can simply be done like this :

While you are compiling the coffeescript, use the "-b" parameter.

-b / --bare Compile the JavaScript without the top-level function safety wrapper.

So something like this : coffee -b --compile somefile.coffee whatever.js

This will output your code just like in the CoffeeScript.org site.

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

Here is the solution without scripting and no external jars like ant-conrib:

The trick is to use ANT's resources:

• There is one resource type called "propertyresource" which is like a source file, but provides an stream from the string value of this resource. So you can load it and use it in any task like "copy" that accepts files
• There is also the task "loadresource" that can load any resource to a property (e.g., a file), but this one could also load our propertyresource. This task allows for filtering the input by applying some token transformations. Finally the following will do what you want:

<loadresource property="propB">
  <propertyresource name="propA"/>
  <filterchain>
    <tokenfilter>
      <filetokenizer/>
      <replacestring from=" " to="_"/>
    </tokenfilter>
  </filterchain>
</loadresource>

This one will replace all " " in propA by "_" and place the result in propB. "filetokenizer" treats the whole input stream (our property) as one token and appies the string replacement on it.

You can do other fancy transformations using other tokenfilters: http://ant.apache.org/manual/Types/filterchain.html

600851475143 cannot be represented as a 32-bit integer (type int). It can be represented as a 64-bit integer (type long). long literals in Java end with an "L": 600851475143L

Maybe better document.querySelectorAll(".col1") because getElementsByClassName doesn't works in IE 8 and querySelectorAll does (althought CSS2 selectors only).

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementsByClassName https://developer.mozilla.org/en-US/docs/Web/API/Document.querySelectorAll

You can try this with your nav div:

postion: fixed;
top: 0;
width: 100%;

Every undeclared variable in c error comes because the compiler is not able to find it in the project. One can include the external (header) file of the library in which the variable is defined. Hence in your question, you require <stdio.h>, that is a standard input output file, which describes printf(), functionality.

According to the documentation, the declaration of fprintf() is in i.e. you have to include it, before using the function.

Files will be deleted from your app's document directory when the user uninstalls the app. Knowing this, all you have to do is check whether a file exists as the first thing that happens in application:didFinishLaunchingWithOptions:. Afterwards, unconditionally create the file (even if it's just a dummy file).

If the file did not exist at time of check, you know this is the first run since the latest install. If you need to know later in the app, save the boolean result to your app delegate member.

Maven already has a solution to do what you want:

Get MavenProject from just the POM.xml - pom parser?

btw: first hit at google search ;)

Model model = null;
FileReader reader = null;
MavenXpp3Reader mavenreader = new MavenXpp3Reader();

try {
     reader = new FileReader(pomfile); // <-- pomfile is your pom.xml
     model = mavenreader.read(reader);
     model.setPomFile(pomfile);
}catch(Exception ex){
     // do something better here
     ex.printStackTrace()
}

MavenProject project = new MavenProject(model);
project.getProperties() // <-- thats what you need

Go ahead and use Lombok, you can if necessary "delombok" your code afterwards http://projectlombok.org/features/delombok.html

You need to use \" for escaping " character (\ escape the following character

sed -i 's/\"http://www.fubar.com\"/URL_FUBAR/g'

byte test[] = new byte[3];
test[0] = 0x0A;
test[1] = 0xFF;
test[2] = 0x01;

for (byte theByte : test)
{
  System.out.println(Integer.toHexString(theByte));
}

NOTE: test[1] = 0xFF; this wont compile, you cant put 255 (FF) into a byte, java will want to use an int.

you might be able to do...

test[1] = (byte) 0xFF;

I'd test if I was near my IDE (if I was near my IDE I wouln't be on Stackoverflow)

You use File.separator because someday your program might run on a platform developed in a far-off land, a land of strange things and stranger people, where horses cry and cows operate all the elevators. In this land, people have traditionally used the ":" character as a file separator, and so dutifully the JVM obeys their wishes.

I just wanted to follow up on something I found working with Python 2.7 on Centos 6. Adding the package_data or data_files as mentioned above did not work for me. I added a MANIFEST.IN with the files I wanted which put the non-python files into the tarball, but did not install them on the target machine via RPM.

In the end, I was able to get the files into my solution using the "options" in the setup/setuptools. The option files let you modify various sections of the spec file from setup.py. As follows.

from setuptools import setup


setup(
    name='theProjectName',
    version='1',
    packages=['thePackage'],
    url='',
    license='',
    author='me',
    author_email='[email protected]',
    description='',
    options={'bdist_rpm': {'install_script': 'filewithinstallcommands'}},
)

file - MANIFEST.in:

include license.txt

file - filewithinstallcommands:

mkdir -p $RPM_BUILD_ROOT/pathtoinstall/
#this line installs your python files
python setup.py install -O1 --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES
#install license.txt into /pathtoinstall folder
install -m 700 license.txt $RPM_BUILD_ROOT/pathtoinstall/
echo /pathtoinstall/license.txt >> INSTALLED_FILES

It's allowed because authors decided to allow it: https://docs.python.org/2/reference/simple_stmts.html

If move to question why authors decided todo so, I guess it's so because semi-column is allowed as simple statement termination at least in the following langages: C++, C, C#, R, Matlab,Perl,...

So it's faster to move into usage of Python for people with background in other language. And there are no lose of generality in such deicison.

The classpath setting of the compiler plugin are two args. Changed it like this and it worked for me:

<configuration>
  <compilerArgs>
     <arg>-cp</arg>
     <arg>${cp}:${basedir}/lib/bad.jar</arg>
  </compilerArgs>
</configuration>

I used the gmavenplus-plugin to read the path and create the property 'cp':

      <plugin>
    <!--
      Use Groovy to read classpath and store into
      file named value of property <cpfile>

      In second step use Groovy to read the contents of
      the file into a new property named <cp>

      In the compiler plugin this is used to create a
      valid classpath

In IntelliJ IDEA 14, it has moved to: File -> Settings -> Editor -> General -> "Show quick doc on mouse move"

You can use ISNULL and check the answer against the known output:

SELECT case when ISNULL(col1, '') = '' then '' else col1 END AS COL1 FROM TEST

arr[title] = link;

You're not pushing into the array, you're setting the element with the key title to the value link. As such your array should be an object.

The reason for the error is that the host server for https://cw.na1.hgncloud.com has provided some HTTP headers to protect the document. One of which is that the frame ancestors must be from the same domain as the original content. It seems you are attempting to put the iframe at a domain location that is not the same as the content of the iframe - thus violating the Content Security Policy that the host has set.

Check out this link on Content Security Policy for more details.

I had also faced the same issue, after few searches, I found a solution that worked for me.I hope it will help you. As you have already created users, now try to do a FLUSH PRIVILEGES on your Mysql console. This issue is already in MySql bug post.You can also check this one.Now after flushing, you can create a new user. follow below Steps:

Step-1: Open terminal Ctrl+Alt+T
Step-2: mysql -u root -p  , it will ask for your MySQL password.

Now you can able to see Mysql console.

Step-3: CREATE USER 'username'@'host' IDENTIFIED by 'PASSWORD';

Instead of username you can put username you want. If you are running Mysql on your local machine, then type "localhost" instead of the host, otherwise give your server name you want to access.

Ex: CREATE USER smruti@localhost IDENTIFIED by 'hello';

Now new user is created. If you want to give all access then type

GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';

Now you can quit the MySQL by typing \q.Now once again login through

mysql -u newusername -p , then press Enter. You can see everything.

Hope this helps.

I setup a short cut (using windows) and set the target to

C:\Python36\pythonw.exe c:/python36/Lib/idlelib/idle.py

works great

Also found this works

with open('FILE.py') as f:
    exec(f.read())

You can use header to send the right Content-type :

header('Content-Type: ' . $type);

And readfile to output the content of the image :

readfile($file);

And maybe (probably not necessary, but, just in case) you'll have to send the Content-Length header too :

header('Content-Length: ' . filesize($file));

Note : make sure you don't output anything else than your image data (no white space, for instance), or it will no longer be a valid image.

I use this Swift 5, pure Core Graphics extension that correctly handles non-zero origins in image rects:

extension CGContext {

    /// Draw `image` flipped vertically, positioned and scaled inside `rect`.
    public func drawFlipped(_ image: CGImage, in rect: CGRect) {
        self.saveGState()
        self.translateBy(x: 0, y: rect.origin.y + rect.height)
        self.scaleBy(x: 1.0, y: -1.0)
        self.draw(image, in: CGRect(origin: CGPoint(x: rect.origin.x, y: 0), size: rect.size))
        self.restoreGState()
    }
}

You can use it exactly like CGContext's regular draw(: in:) method:

ctx.drawFlipped(myImage, in: myRect)

Modern HTML5 Techniques for changing classes

Modern browsers have added classList which provides methods to make it easier to manipulate classes without needing a library:

document.getElementById("MyElement").classList.add('MyClass');

document.getElementById("MyElement").classList.remove('MyClass');

if ( document.getElementById("MyElement").classList.contains('MyClass') )

document.getElementById("MyElement").classList.toggle('MyClass');

Unfortunately, these do not work in Internet Explorer prior to v10, though there is a shim to add support for it to IE8 and IE9, available from this page. It is, though, getting more and more supported.

Simple cross-browser solution

The standard JavaScript way to select an element is using document.getElementById("Id"), which is what the following examples use - you can of course obtain elements in other ways, and in the right situation may simply use this instead - however, going into detail on this is beyond the scope of the answer.

To change all classes for an element:

To replace all existing classes with one or more new classes, set the className attribute:

document.getElementById("MyElement").className = "MyClass";

(You can use a space-delimited list to apply multiple classes.)

To add an additional class to an element:

To add a class to an element, without removing/affecting existing values, append a space and the new classname, like so:

document.getElementById("MyElement").className += " MyClass";

To remove a class from an element:

To remove a single class to an element, without affecting other potential classes, a simple regex replace is required:

document.getElementById("MyElement").className =
   document.getElementById("MyElement").className.replace
      ( /(?:^|\s)MyClass(?!\S)/g , '' )
/* Code wrapped for readability - above is all one statement */

An explanation of this regex is as follows:

(?:^|\s) # Match the start of the string or any single whitespace character

MyClass  # The literal text for the classname to remove

(?!\S)   # Negative lookahead to verify the above is the whole classname
         # Ensures there is no non-space character following
         # (i.e. must be the end of the string or space)

The g flag tells the replace to repeat as required, in case the class name has been added multiple times.

To check if a class is already applied to an element:

The same regex used above for removing a class can also be used as a check as to whether a particular class exists:

if ( document.getElementById("MyElement").className.match(/(?:^|\s)MyClass(?!\S)/) )

Whilst it is possible to write JavaScript directly inside the HTML event attributes (such as onclick="this.className+=' MyClass'") this is not recommended behaviour. Especially on larger applications, more maintainable code is achieved by separating HTML markup from JavaScript interaction logic.

The first step to achieving this is by creating a function, and calling the function in the onclick attribute, for example:

<script type="text/javascript">
    function changeClass(){
        // Code examples from above
    }
</script>
...
<button onclick="changeClass()">My Button</button>

_{(It is not required to have this code in script tags, this is simply for the brevity of example, and including the JavaScript in a distinct file may be more appropriate.)}

The second step is to move the onclick event out of the HTML and into JavaScript, for example using addEventListener

<script type="text/javascript">
    function changeClass(){
        // Code examples from above
    }

    window.onload = function(){
        document.getElementById("MyElement").addEventListener( 'click', changeClass);
    }
</script>
...
<button id="MyElement">My Button</button>

(Note that the window.onload part is required so that the contents of that function are executed after the HTML has finished loading - without this, the MyElement might not exist when the JavaScript code is called, so that line would fail.)

JavaScript Frameworks and Libraries

The above code is all in standard JavaScript, however, it is common practice to use either a framework or a library to simplify common tasks, as well as benefit from fixed bugs and edge cases that you might not think of when writing your code.

Whilst some people consider it overkill to add a ~50  KB framework for simply changing a class, if you are doing any substantial amount of JavaScript work or anything that might have unusual cross-browser behavior, it is well worth considering.

(Very roughly, a library is a set of tools designed for a specific task, whilst a framework generally contains multiple libraries and performs a complete set of duties.)

The examples above have been reproduced below using jQuery, probably the most commonly used JavaScript library (though there are others worth investigating too).

(Note that $ here is the jQuery object.)

Changing Classes with jQuery:

$('#MyElement').addClass('MyClass');

$('#MyElement').removeClass('MyClass');

if ( $('#MyElement').hasClass('MyClass') )

In addition, jQuery provides a shortcut for adding a class if it doesn't apply, or removing a class that does:

$('#MyElement').toggleClass('MyClass');

$('#MyElement').click(changeClass);

or, without needing an id:

$(':button:contains(My Button)').click(changeClass);

first install fontawsome using npm

npm install --save @fortawesome/fontawesome-free

add to resources\sass\app.scss

// Fonts
@import '~@fortawesome/fontawesome-free/scss/fontawesome';

and add to resources\js\app.js

require('@fortawesome/fontawesome-free/js/all.js');

then run

npm run dev

or

npm run production

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

Avoid sqlite3_clear_bindings(stmt).

The code in the test sets the bindings every time through which should be enough.

The C API intro from the SQLite docs says:

Prior to calling sqlite3_step() for the first time or immediately after sqlite3_reset(), the application can invoke the sqlite3_bind() interfaces to attach values to the parameters. Each call to sqlite3_bind() overrides prior bindings on the same parameter

There is nothing in the docs for sqlite3_clear_bindings saying you must call it in addition to simply setting the bindings.

More detail: Avoid_sqlite3_clear_bindings()

You Can simply Right Click Formula Fields- > new Give it a name like TotalCount then Right this code:

if(isnull(sum(count({YOURCOLUMN})))) then
0
else
(sum(count({YOURCOLUMN})))

and Save then Drag and drop TotalCount this field in header/footer. After you open the "count" bracket you can drop your column there from the above section.See the example in the Picture

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

>>> [1]

Either escape the double quotes with \

String xmlString = "<element attribname=\"value\" attribname1=\"value1\"> pcdata</element>"

or use single quotes instead

String xmlString = "<element attribname='value' attribname1='value1'> pcdata</element>"

Installing Aptana Studio in passive mode bypasses the installation of Git for Windows and Node.js.

Aptana_Studio_3_Setup_3.6.1 /passive /norestart

(I am unsure whether Aptana Studio will work properly without those "prerequisites", but it appears to.)

If you want a global installation in a specific directory, the command line is

Aptana_Studio_3_Setup_3.6.1.exe /passive /norestart ALLUSERS=1 APPDIR=c:\apps\AptanaStudio

You make one div somewhere on the page and put this code:

<div id="winSize"></div>
<script>
    var WindowsSize=function(){
        var h=$(window).height(),
            w=$(window).width();
        $("#winSize").html("<p>Width: "+w+"<br>Height: "+h+"</p>");
    };
   $(document).ready(WindowsSize); 
   $(window).resize(WindowsSize); 
</script>

Here is a snippet:

var WindowsSize=function(){_x000D_
     var h=$(window).height(),_x000D_
      w=$(window).width();_x000D_
     $("#winSize").html("<p>Width: "+w+"<br>Height:"+h+"</p>");_x000D_
 };_x000D_
 $(document).ready(WindowsSize); _x000D_
 $(window).resize(WindowsSize); 

#winSize{_x000D_
  position:fixed;_x000D_
  bottom:1%;_x000D_
  right:1%;_x000D_
  border:rgba(0,0,0,0.8) 3px solid;_x000D_
  background:rgba(0,0,0,0.6);_x000D_
  padding:5px 10px;_x000D_
  color:#fff;_x000D_
  text-shadow:#000 1px 1px 1px,#000 -1px 1px 1px;_x000D_
  z-index:9999_x000D_
}

<div id="winSize"></div>

Of course, adapt it to fit your needs! ;)

I had the same error when I create the SQL db in a VM. I had changed the default value of /etc/postgresql/9.3/main/postgresql.conf shared_buffers = 200MB to 75% of my total RAM. Well, I forgot to actually allocate that RAM in the VM. When I gave the command to make a new database, I received the same error.

Powered off, gave the baby its bottle (RAM) and presto, it worked.

For those looking for an answer in Oracle:

SELECT column_name FROM user_tab_columns WHERE table_name = 'TABLENAME'

A quick and dirty way (maybe for testing) could be to directly use the exec or spawn method to invoke OS call to remove the directory. Read more on NodeJs child_process.

let exec = require('child_process').exec
exec('rm -Rf /tmp/*.zip', callback)

Downsides are:

1. You are depending on underlying OS i.e. the same method would run in unix/linux but probably not in windows.
2. You cannot hijack the process on conditions or errors. You just give the task to underlying OS and wait for the exit code to be returned.

Benefits:

1. These processes can run asynchronously.
2. You can listen for the output/error of the command, hence command output is not lost. If operation is not completed, you can check the error code and retry.

That you can handle the checked and unchecked events seperately doesn't mean you have to. If you don't want to follow the MVVM pattern you can simply attach the same handler to both events and you have your change signal:

<CheckBox Checked="CheckBoxChanged" Unchecked="CheckBoxChanged"/>

and in Code-behind;

private void CheckBoxChanged(object sender, RoutedEventArgs e)
{
  MessageBox.Show("Eureka, it changed!");
}

Please note that WPF strongly encourages the MVVM pattern utilizing INotifyPropertyChanged and/or DependencyProperties for a reason. This is something that works, not something I would like to encourage as good programming habit.

make sure you use the POST to insert the data. Actually you were using GET.

This should do it:

l[4] = -1

You will find the application folder at:

/data/data/"your package name"

you can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.

Can use static block for initialization:

private static Set<Integer> codes1=
        new HashSet<Integer>(Arrays.asList(1, 2, 3, 4));

private static Set<Integer> codes2 =
        new HashSet<Integer>(Arrays.asList(5, 6, 7, 8));

private static Set<Integer> h = new HashSet<Integer>();

static{
    h.add(codes1);
    h.add(codes2);
}

It sounds like you have a form tag in a Master Page and in the Page that is throwing the error.

You can have only one.

You can use store object that is returned from createStore function (which should be already used in your code in app initialization). Than you can use this object to get current state with store.getState() method or store.subscribe(listener) to subscribe to store updates.

You can even save this object to window property to access it from any part of application if you really want it (window.store = store)

Many developers include files by pointing to a remote URL, even if the file is within the local system. For example:

<php include("http://example.com/includes/example_include.php"); ?>

With allow_url_include disabled, this method does not work. Instead, the file must be included with a local path, and there are three methods of doing this:

By using a relative path, such as ../includes/example_include.php. By using an absolute path (also known as relative-from-root), such as /home/username/example.com/includes/example_include.php.

By using the PHP environment variable $_SERVER['DOCUMENT_ROOT'], which returns the absolute path to the web root directory. This is by far the best (and most portable) solution. The following example shows the environment variable in action.

Example Include

<?php include($_SERVER['DOCUMENT_ROOT']."/includes/example_include.php"); ?>

strstr(request, "favicon") != NULL

Give name and values to those submit buttons like:

    <td>
    <input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
    </td>
    <td>
    <input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
    </td>

and then in your php script you could check

if($_POST['mybutton'] == 'save')
{
  ///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
  ///do publish processing here
}

In merge-sort, the general algorithm is:

1. Sort the left sub-array
2. Sort the right sub-array
3. Merge the 2 sorted sub-arrays

At the top level, merging the 2 sorted sub-arrays involves dealing with N elements.

One level below that, each iteration of step 3 involves dealing with N/2 elements, but you have to repeat this process twice. So you're still dealing with 2 * N/2 == N elements.

One level below that, you're merging 4 * N/4 == N elements, and so on. Every depth in the recursive stack involves merging the same number of elements, across all calls for that depth.

Consider the quick-sort algorithm instead:

1. Pick a pivot point
2. Place the pivot point at the correct place in the array, with all smaller elements to the left, and larger elements to the right
3. Sort the left-subarray
4. Sort the right-subarray

At the top level, you're dealing with an array of size N. You then pick one pivot point, put it in its correct position, and can then ignore it completely for the rest of the algorithm.

One level below that, you're dealing with 2 sub-arrays that have a combined size of N-1 (ie, subtract the earlier pivot point). You pick a pivot point for each sub-array, which comes up to 2 additional pivot points.

One level below that, you're dealing with 4 sub-arrays with combined size N-3, for the same reasons as above.

Then N-7... Then N-15... Then N-32...

The depth of your recursive stack remains approximately the same (logN). With merge-sort, you're always dealing with a N-element merge, across each level of the recursive stack. With quick-sort though, the number of elements that you're dealing with diminishes as you go down the stack. For example, if you look at the depth midway through the recursive stack, the number of elements you're dealing with is N - 2^((logN)/2)) == N - sqrt(N).

Disclaimer: On merge-sort, because you divide the array into 2 exactly equal chunks each time, the recursive depth is exactly logN. On quick-sort, because your pivot point is unlikely to be exactly in the middle of the array, the depth of your recursive stack may be slightly greater than logN. I haven't done the math to see how big a role this factor and the factor described above, actually play in the algorithm's complexity.

In the solution below I used python3.4 as binary, but it's safe to use with any version or binary of python. it works fine on windows too (except the downloading pip with wget obviously but just save the file locally and run it with python).

This is great if you have multiple versions of python installed, so you can manage external libraries per python version.

So first, I'd recommend get-pip.py, it's great to install pip :

wget https://bootstrap.pypa.io/get-pip.py

Then you need to install pip for your version of python, I have python3.4 so for me this is the command :

python3.4 get-pip.py

Now pip is installed for python3.4 and in order to get libraries for python3.4 one need to call it within this version, like this :

python3.4 -m pip

So if you want to install numpy you would use :

python3.4 -m pip install numpy

Note that numpy is quite the heavy library. I thought my system was hanging and failing. But using the verbose option, you can see that the system is fine :

python3.4 -m pip install numpy -v

This may tell you that you lack python.h but you can easily get it :

On RHEL (Red hat, CentOS, Fedora) it would be something like this :

yum install python34-devel

On debian-like (Debian, Ubuntu, Kali, ...) :

apt-get install python34-dev

Then rerun this :

python3.4 -m pip install numpy -v

I faced same issue & it resolved by

ENTRYPOINT ["sh", "/docker-entrypoint.sh"]

For the Dockerfile in the original question it should be like:

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

If you're already in conflicted state...

git checkout --theirs path/to/file

You shouldn't search through that array, but use database capabilities for this
Suppose you're passing username through GET form:

if (isset($_GET['search'])) {
  $search = mysql_real_escape_string($_GET['search']);
  $sql = "SELECT * FROM users WHERE username = '$search'";
  $res = mysql_query($sql) or trigger_error(mysql_error().$sql);
  $row = mysql_fetch_assoc($res);
  if ($row){
    print_r($row); //do whatever you want with found info
  }
}

I had similar problem when had to upload file and send user token info at the same time. transformRequest along with forming FormData helped:

        $http({
            method: 'POST',
            url: '/upload-file',
            headers: {
                'Content-Type': 'multipart/form-data'
            },
            data: {
                email: Utils.getUserInfo().email,
                token: Utils.getUserInfo().token,
                upload: $scope.file
            },
            transformRequest: function (data, headersGetter) {
                var formData = new FormData();
                angular.forEach(data, function (value, key) {
                    formData.append(key, value);
                });

                var headers = headersGetter();
                delete headers['Content-Type'];

                return formData;
            }
        })
        .success(function (data) {

        })
        .error(function (data, status) {

        });

For getting file $scope.file I used custom directive:

app.directive('file', function () {
    return {
        scope: {
            file: '='
        },
        link: function (scope, el, attrs) {
            el.bind('change', function (event) {
                var file = event.target.files[0];
                scope.file = file ? file : undefined;
                scope.$apply();
            });
        }
    };
});

Html:

<input type="file" file="file" required />

The Mozilla Developer Network provides the following explanation:

1. Create an event using event = document.createEvent("KeyboardEvent")
2. Init the keyevent

using:

event.initKeyEvent (type, bubbles, cancelable, viewArg, 
       ctrlKeyArg, altKeyArg, shiftKeyArg, metaKeyArg, 
           keyCodeArg, charCodeArg)

3. Dispatch the event using yourElement.dispatchEvent(event)

I don't see the last one in your code, maybe that's what you're missing. I hope this works in IE as well...

I think the question is a little bit fuzzy - for example, it can be interpreted as a question about best practices in programming loops with if inside. So, I'll try to answer this question with this particular interpretation.

If you have if inside a loop, then in most cases you'd like to know how the loop has ended - was it "broken" by the if or was it ended "naturally"? So, your sample code can be modified in this way:

bool intMaxFound = false;
for (size = 0; size < HAY_MAX; size++)
{
  // wait for hay until EOF
  printf("\nhaystack[%d] = ", size);
  int straw = GetInt();
  if (straw == INT_MAX)
     {intMaxFound = true; break;}

  // add hay to stack
  haystack[size] = straw;
}
if (intMaxFound)
{
  // ... broken
}
else
{
  // ... ended naturally
}

The problem with this code is that the if statement is buried inside the loop body, and it takes some effort to locate it and understand what it does. A more clear (even without the break statement) variant will be:

bool intMaxFound = false;
for (size = 0; size < HAY_MAX && !intMaxFound; size++)
{
  // wait for hay until EOF
  printf("\nhaystack[%d] = ", size);
  int straw = GetInt();
  if (straw == INT_MAX)
     {intMaxFound = true; continue;}

  // add hay to stack
  haystack[size] = straw;
}
if (intMaxFound)
{
  // ... broken
}
else
{
  // ... ended naturally
}

In this case you can clearly see (just looking at the loop "header") that this loop can end prematurely. If the loop body is a multi-page text, written by somebody else, then you'd thank its author for saving your time.

UPDATE:

Thanks to SO - it has just suggested the already answered question about crash of the AT&T phone network in 1990. It's about a risky decision of C creators to use a single reserved word break to exit from both loops and switch.

Anyway this interpretation doesn't follow from the sample code in the original question, so I'm leaving my answer as it is.

To put a require rule on a select list you just need an option with an empty value

<option value="">Year</option>

then just applying required on its own is enough

<script>
    $(function () {
        $("form").validate();
    });
</script>

with form

<form>
<select name="year" id="year" class="required">
    <option value="">Year</option>
    <option value="1">1919</option>
    <option value="2">1920</option>
    <option value="3">1921</option>
    <option value="4">1922</option>
</select>
<input type="submit" />
</form>

It's a "precompiled header file" -- any headers you include in stdafx.h are pre-processed to save time during subsequent compilations. You can read more about it here on MSDN.

If you're building a cross-platform application, check "Empty project" when creating your project and Visual Studio won't put any files at all in your project.

Here's a great tip that nobody mentioned. In the controller that the function is within, you need to include the location provider:

app.controller('SlideController', ['$scope', '$location',function($scope, $location){ 
$scope.goNext = function (hash) { 
$location.path(hash);
 }

;]);

 <!--the code to call it from within the partial:---> <div ng-click='goNext("/page2")'>next page</div>

This solution is purely using ng tag on HTML.

The solution is to limit the long text displayed with 'show more...' link at the end of it. If user click 'show more...' link, it will show the rest of the text and removed the 'show more...' link.

HTML:

<div ng-init="limitText=160">
   <p>{{ veryLongText | limitTo: limitText }} 
       <a href="javascript:void(0)" 
           ng-hide="veryLongText.length < limitText" 
           ng-click="limitText = veryLongText.length + 1" > show more..
       </a>
   </p>
</div>

Changing the IDENTITY property is really a metadata only change. But to update the metadata directly requires starting the instance in single user mode and messing around with some columns in sys.syscolpars and is undocumented/unsupported and not something I would recommend or will give any additional details about.

For people coming across this answer on SQL Server 2012+ by far the easiest way of achieving this result of an auto incrementing column would be to create a SEQUENCE object and set the next value for seq as the column default.

Alternatively, or for previous versions (from 2005 onwards), the workaround posted on this connect item shows a completely supported way of doing this without any need for size of data operations using ALTER TABLE...SWITCH. Also blogged about on MSDN here. Though the code to achieve this is not very simple and there are restrictions - such as the table being changed can't be the target of a foreign key constraint.

Example code.

Set up test table with no identity column.

CREATE TABLE dbo.tblFoo 
(
bar INT PRIMARY KEY,
filler CHAR(8000),
filler2 CHAR(49)
)


INSERT INTO dbo.tblFoo (bar)
SELECT TOP (10000) ROW_NUMBER() OVER (ORDER BY (SELECT 0))
FROM master..spt_values v1, master..spt_values v2

Alter it to have an identity column (more or less instant).

BEGIN TRY;
    BEGIN TRANSACTION;

    /*Using DBCC CHECKIDENT('dbo.tblFoo') is slow so use dynamic SQL to
      set the correct seed in the table definition instead*/
    DECLARE @TableScript nvarchar(max)
    SELECT @TableScript = 
    '
    CREATE TABLE dbo.Destination(
        bar INT IDENTITY(' + 
                     CAST(ISNULL(MAX(bar),0)+1 AS VARCHAR) + ',1)  PRIMARY KEY,
        filler CHAR(8000),
        filler2 CHAR(49)
        )

        ALTER TABLE dbo.tblFoo SWITCH TO dbo.Destination;
    '       
    FROM dbo.tblFoo
    WITH (TABLOCKX,HOLDLOCK)

    EXEC(@TableScript)


    DROP TABLE dbo.tblFoo;

    EXECUTE sp_rename N'dbo.Destination', N'tblFoo', 'OBJECT';


    COMMIT TRANSACTION;
END TRY
BEGIN CATCH
    IF XACT_STATE() <> 0 ROLLBACK TRANSACTION;
    PRINT ERROR_MESSAGE();
END CATCH;

Test the result.

INSERT INTO dbo.tblFoo (filler,filler2) 
OUTPUT inserted.*
VALUES ('foo','bar')

Gives

bar         filler    filler2
----------- --------- ---------
10001       foo       bar      

Clean up

DROP TABLE dbo.tblFoo

I achieved an infinite scrolling type implementation using this logic in the onBindViewHolder method of my RecyclerView.Adapter class.

    if (position == mItems.size() - 1 && mCurrentPage <= mTotalPageCount) {
        if (mCurrentPage == mTotalPageCount) {
            mLoadImagesListener.noMorePages();
        } else {
            int newPage = mCurrentPage + 1;
            mLoadImagesListener.loadPage(newPage);
        }
    }

With this code when the RecyclerView gets to the last item, it increments the current page and callbacks on an interface which is responsible for loading more data from the api and adding the new results to the adapter.

I can post more complete example if this isn't clear?

Another way to do this:

<ul>
  <li>One</li>
  <li>Two</li>
  <li>Three</li>
</ul>

ul {
  width: auto;
  display: table;
  margin-left: auto;
  margin-right: auto;
}

ul li {
  float: left;
  list-style: none;
  margin-right: 1rem;
}

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

What type of variable is format?

From a java POV, format is an implemtation of an anonymous interface. This interface has one method named for each mime type. When you invoke one of those methods (passing it a block), then if rails feels that the user wants that content type, then it will invoke your block.

The twist, of course, is that this anonymous glue object doesn't actually implement an interface - it catches the method calls dynamically and works out if its the name of a mime type that it knows about.

Personally, I think it looks weird: the block that you pass in is executed. It would make more sense to me to pass in a hash of format labels and blocks. But - that's how its done in RoR, it seems.

1. fork() - creates a new child process, which is a complete copy of the parent process. Child and parent processes use different virtual address spaces, which is initially populated by the same memory pages. Then, as both processes are executed, the virtual address spaces begin to differ more and more, because the operating system performs a lazy copying of memory pages that are being written by either of these two processes and assigns an independent copies of the modified pages of memory for each process. This technique is called Copy-On-Write (COW).
2. vfork() - creates a new child process, which is a "quick" copy of the parent process. In contrast to the system call fork(), child and parent processes share the same virtual address space. NOTE! Using the same virtual address space, both the parent and child use the same stack, the stack pointer and the instruction pointer, as in the case of the classic fork()! To prevent unwanted interference between parent and child, which use the same stack, execution of the parent process is frozen until the child will call either exec() (create a new virtual address space and a transition to a different stack) or _exit() (termination of the process execution). vfork() is the optimization of fork() for "fork-and-exec" model. It can be performed 4-5 times faster than the fork(), because unlike the fork() (even with COW kept in the mind), implementation of vfork() system call does not include the creation of a new address space (the allocation and setting up of new page directories).
3. clone() - creates a new child process. Various parameters of this system call, specify which parts of the parent process must be copied into the child process and which parts will be shared between them. As a result, this system call can be used to create all kinds of execution entities, starting from threads and finishing by completely independent processes. In fact, clone() system call is the base which is used for the implementation of pthread_create() and all the family of the fork() system calls.
4. exec() - resets all the memory of the process, loads and parses specified executable binary, sets up new stack and passes control to the entry point of the loaded executable. This system call never return control to the caller and serves for loading of a new program to the already existing process. This system call with fork() system call together form a classical UNIX process management model called "fork-and-exec".

Well if you are new to C# with cmd-line exp. you can use online sites like "https://curl.olsh.me/" or search curl to C# converter will returns site that could do that for you.

If IsNull({TABLE.FIELD1}) then "NULL" +',' + {TABLE.FIELD2} else {TABLE.FIELD1} + ', ' + {TABLE.FIELD2}

Here I put NULL as string to display the string value NULL in place of the null value in the data field. Hope you understand.

you could use either PowerISO or WinRAR

D = {} is a dictionary not set.

>>> d = {}
>>> type(d)
<type 'dict'>

Use D = set():

>>> d = set()
>>> type(d)
<type 'set'>
>>> d.update({1})
>>> d.add(2)
>>> d.update([3,3,3])
>>> d
set([1, 2, 3])

Try one of these:

• ApplicationRef.tick() - similar to AngularJS's $rootScope.$digest() -- i.e., check the full component tree
• NgZone.run(callback) - similar to $rootScope.$apply(callback) -- i.e., evaluate the callback function inside the Angular zone. I think, but I'm not sure, that this ends up checking the full component tree after executing the callback function.
• ChangeDetectorRef.detectChanges() - similar to $scope.$digest() -- i.e., check only this component and its children

You can inject ApplicationRef, NgZone, or ChangeDetectorRef into your component.

With regular expressions

import re
s="""
    qwertyuiop
    asdfghjkl

    zxcvbnm
    token qwerty

    asdfghjklñ
"""
>>> items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:
...     print x
...
token qwerty

An object can't be null - the value of an expression can be null. It's worth making the difference clear in your mind. The value of s isn't an object - it's a reference, which is either null or refers to an object.

And yes, you should just use

if (s == null)

Note that this will still use the overloaded == operator defined in string, but that will do the right thing.

Is this possible using HttpWebRequest and HttpWebResponse?

You could have your web server simply catch and write the exception text into the body of the response, then set status code to 500. Now the client would throw an exception when it encounters a 500 error but you could read the response stream and fetch the message of the exception.

So you could catch a WebException which is what will be thrown if a non 200 status code is returned from the server and read its body:

catch (WebException ex)
{
    using (var stream = ex.Response.GetResponseStream())
    using (var reader = new StreamReader(stream))
    {
        Console.WriteLine(reader.ReadToEnd());
    }
}
catch (Exception ex)
{
    // Something more serious happened
    // like for example you don't have network access
    // we cannot talk about a server exception here as
    // the server probably was never reached
}

Try jquery debugger plugin if you're using chrome: https://chrome.google.com/webstore/detail/jquery-debugger/dbhhnnnpaeobfddmlalhnehgclcmjimi?hl=en

var dict = []; // create an empty array

dict.push({
    key:   "keyName",
    value: "the value"
});
// repeat this last part as needed to add more key/value pairs

Basically, you're creating an object literal with 2 properties (called key and value) and inserting it (using push()) into the array.

Edit: So almost 5 years later, this answer is getting downvotes because it's not creating an "normal" JS object literal (aka map, aka hash, aka dictionary).
It is however creating the structure that OP asked for (and which is illustrated in the other question linked to), which is an array of object literals, each with key and value properties. Don't ask me why that structure was required, but it's the one that was asked for.

But, but, if what you want in a plain JS object - and not the structure OP asked for - see tcll's answer, though the bracket notation is a bit cumbersome if you just have simple keys that are valid JS names. You can just do this:

// object literal with properties
var dict = {
  key1: "value1",
  key2: "value2"
  // etc.
};

Or use regular dot-notation to set properties after creating an object:

// empty object literal with properties added afterward
var dict = {};
dict.key1 = "value1";
dict.key2 = "value2";
// etc.

You do want the bracket notation if you've got keys that have spaces in them, special characters, or things like that. E.g:

var dict = {};

// this obviously won't work
dict.some invalid key (for multiple reasons) = "value1";

// but this will
dict["some invalid key (for multiple reasons)"] = "value1";

You also want bracket notation if your keys are dynamic:

dict[firstName + " " + lastName] = "some value";

Note that keys (property names) are always strings, and non-string values will be coerced to a string when used as a key. E.g. a Date object gets converted to its string representation:

dict[new Date] = "today's value";

console.log(dict);
// => {
//      "Sat Nov 04 2016 16:15:31 GMT-0700 (PDT)": "today's value"
//    }

Note however that this doesn't necessarily "just work", as many objects will have a string representation like "[object Object]" which doesn't make for a non-unique key. So be wary of something like:

var objA = { a: 23 },
    objB = { b: 42 };

dict[objA] = "value for objA";
dict[objB] = "value for objB";

console.log(dict);
// => { "[object Object]": "value for objB" }

Despite objA and objB being completely different and unique elements, they both have the same basic string representation: "[object Object]".

The reason Date doesn't behave like this is that the Date prototype has a custom toString method which overrides the default string representation. And you can do the same:

// a simple constructor with a toString prototypal method
function Foo() {
  this.myRandomNumber = Math.random() * 1000 | 0;
}

Foo.prototype.toString = function () {
  return "Foo instance #" + this.myRandomNumber;
};

dict[new Foo] = "some value";

console.log(dict);
// => {
//      "Foo instance #712": "some value"
//    }

(Note that since the above uses a random number, name collisions can still occur very easily. It's just to illustrate an implementation of toString.)

So when trying to use objects as keys, JS will use the object's own toString implementation, if any, or use the default string representation.

Utility git wizard https://github.com/makelinux/git-wizard counts separately unresolved conflicted changes (collisions) and unmerged files. Conflicts must be resolved manually or with mergetool. Resolved unmerged changes can me added and committed usually with git rebase --continue.

Use a document.ready() event around your call.

$(document).ready(function () {

    $('#memberModal').modal('show');

});

You want your change to sit on top of the current state of the remote branch. So probably you want to pull right before you commit yourself. After that, push your changes again.

"Dirty" local files are not an issue as long as there aren't any conflicts with the remote branch. If there are conflicts though, the merge will fail, so there is no risk or danger in pulling before committing local changes.

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

That's a start. It's not a bad practice to define your longer strings outside of the code that uses them. It's a way to separate data and behavior. Your first option is to join string literals together implicitly by making them adjacent to one another:

("This is the first line of my text, "
"which will be joined to a second.")

Or with line ending continuations, which is a little more fragile, as this works:

"This is the first line of my text, " \
"which will be joined to a second."

But this doesn't:

"This is the first line of my text, " \ 
"which will be joined to a second."

See the difference? No? Well you won't when it's your code either.

The downside to implicit joining is that it only works with string literals, not with strings taken from variables, so things can get a little more hairy when you refactor. Also, you can only interpolate formatting on the combined string as a whole.

Alternatively, you can join explicitly using the concatenation operator (+):

("This is the first line of my text, " + 
"which will be joined to a second.")

Explicit is better than implicit, as the zen of python says, but this creates three strings instead of one, and uses twice as much memory: there are the two you have written, plus one which is the two of them joined together, so you have to know when to ignore the zen. The upside is you can apply formatting to any of the substrings separately on each line, or to the whole lot from outside the parentheses.

Finally, you can use triple-quoted strings:

"""This is the first line of my text
which will be joined to a second."""

This is often my favorite, though its behavior is slightly different as the newline and any leading whitespace on subsequent lines will show up in your final string. You can eliminate the newline with an escaping backslash.

"""This is the first line of my text \
which will be joined to a second."""

This has the same problem as the same technique above, in that correct code only differs from incorrect code by invisible whitespace.

Which one is "best" depends on your particular situation, but the answer is not simply aesthetic, but one of subtly different behaviors.

I had this same issue and here are the specific configuration that I needed to get this to work.

First, go to the VirtualBox preferences -> Network.

For the "Host-only Networks" tab, focus on the vboxnet0.

Click the icon on the left that looks like a screwdriver. For the Adapter tab, fill in the IPv4 Network Address as 192.168.56.1 Fill in the IPv4 Network Mask as 255.255.255.0

For the DHCP Server tab, select the check box for Enable Server to enable the server Fill in the Server Address as 192.168.56.100 Fill in the Server Mask as 255.255.255.0 Fill in the Lower Address Bound as 192.168.56.101 Fill in the Upper Address Bound as 192.168.56.254

The DHCP server part is what was not correct for me and it fixed my problem.

According to Swift 4.2 now it's easily to get random number like this

let randomDouble = Double.random(in: -7.9...12.8)

let randomIntFrom0To10 = Int.random(in: 0 ..< 10)

for more details check this out

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

On Android Studio 1.0.2 you only need to go VCS-> Import into Version control -> Share Project on GitHub.

Pop up will appear asking for the repo name.

Rather than placing an extra scanner.nextLine() each time you want to read something, since it seems you want to accept each input on a new line, you might want to instead changing the delimiter to actually match only newlines (instead of any whitespace, as is the default)

import java.util.Scanner;

class ScannerTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        scanner.useDelimiter("\\n");

        System.out.print("Enter an index: ");
        int index = scanner.nextInt();

        System.out.print("Enter a sentence: ");
        String sentence = scanner.next();

        System.out.println("\nYour sentence: " + sentence);
        System.out.println("Your index: " + index);
    }
}

Thus, to read a line of input, you only need scanner.next() that has the same behavior delimiter-wise of next{Int, Double, ...}

The difference with the "nextLine() every time" approach, is that the latter will accept, as an index also <space>3, 3<space> and 3<space>whatever while the former only accepts 3 on a line on its own

Another way to filter on system apps (works with the example of king9981):

/**
 * Return whether the given PackageInfo represents a system package or not.
 * User-installed packages (Market or otherwise) should not be denoted as
 * system packages.
 * 
 * @param pkgInfo
 * @return
 */
private boolean isSystemPackage(PackageInfo pkgInfo) {
    return ((pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0);
}

From this excellent article on query locks in Postgres, one can get blocked query and blocker query and their information from the following query.

CREATE VIEW lock_monitor AS(
SELECT
  COALESCE(blockingl.relation::regclass::text,blockingl.locktype) as locked_item,
  now() - blockeda.query_start AS waiting_duration, blockeda.pid AS blocked_pid,
  blockeda.query as blocked_query, blockedl.mode as blocked_mode,
  blockinga.pid AS blocking_pid, blockinga.query as blocking_query,
  blockingl.mode as blocking_mode
FROM pg_catalog.pg_locks blockedl
JOIN pg_stat_activity blockeda ON blockedl.pid = blockeda.pid
JOIN pg_catalog.pg_locks blockingl ON(
  ( (blockingl.transactionid=blockedl.transactionid) OR
  (blockingl.relation=blockedl.relation AND blockingl.locktype=blockedl.locktype)
  ) AND blockedl.pid != blockingl.pid)
JOIN pg_stat_activity blockinga ON blockingl.pid = blockinga.pid
  AND blockinga.datid = blockeda.datid
WHERE NOT blockedl.granted
AND blockinga.datname = current_database()
);

SELECT * from lock_monitor;

As the query is long but useful, the article author has created a view for it to simplify it's usage.

Definitely it's blocking because of your use of urllib based on the user agent. This same thing is happening to me with OfferUp. You can create a new class called AppURLopener which overrides the user-agent with Mozilla.

import urllib.request

class AppURLopener(urllib.request.FancyURLopener):
    version = "Mozilla/5.0"

opener = AppURLopener()
response = opener.open('http://httpbin.org/user-agent')

Using service workers, this is finally possible in the truest sense.

1. Create a fake URL. For example /saveAs/myPrettyName.jpg
2. Use URL in <a href, <img src, window.open( url ), absolutely anything that can be done with a "real" URL.
3. Inside the worker, catch the fetch event, and respond with the correct data.

The browser will now suggest myPrettyName.jpg even if the user opens the file in a new tab, and tries to save it there. It will be exactly as if the file had come from the server.

// In the service worker
self.addEventListener( 'fetch', function(e)
{
    if( e.request.url.startsWith( '/blobUri/' ) )
    {
        // Logic to select correct dataUri, and return it as a Response
        e.respondWith( dataURLAsRequest );
    }
});

I use this piece of code, it works OK with me so far. This does not use many fancy features of C++:

bool is_file_exist(const char *fileName)
{
    std::ifstream infile(fileName);
    return infile.good();
}

Use the apply method of a function:-

function mainfunc (func){
    window[func].apply(null, Array.prototype.slice.call(arguments, 1));
} 

Edit: It occurs to me that this would be much more useful with a slight tweak:-

function mainfunc (func){
    this[func].apply(this, Array.prototype.slice.call(arguments, 1));
} 

This will work outside of the browser (this defaults to the global space). The use of call on mainfunc would also work:-

function target(a) {
    alert(a)
}

var o = {
    suffix: " World",
    target: function(s) { alert(s + this.suffix); }
};

mainfunc("target", "Hello");

mainfunc.call(o, "target", "Hello");
