A simple solution using fscanf:

void read_ints (const char* file_name)
{
  FILE* file = fopen (file_name, "r");
  int i = 0;

  fscanf (file, "%d", &i);    
  while (!feof (file))
    {  
      printf ("%d ", i);
      fscanf (file, "%d", &i);      
    }
  fclose (file);        
}

For what it's worth, if you are editing this file, you can probably highlight all the lines and use your un-tab button.

• In Vim, use Shift + V to highlight the lines, then press <<
• If you're on a Mac, then you can use Atom, Sublime Text, etc., then highlight with your mouse and then press Shift + Tab

I am not sure if there is some requirement that this must be done from the command line. If so, then :thumbs-up: to the accepted answer! =)

I actually had an issue where my db was pretty much locked by the processes and a race condition with them, by the time I got one command executed refreshed and they had it locked again... I had to run the following commands back to back in SSMS and got me offline and from there I did my restore and came back online just fine, the two queries where:

First ran:

USE master
GO

DECLARE @kill varchar(8000) = '';
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'
FROM master..sysprocesses 
WHERE dbid = db_id('<yourDbName>')

EXEC(@kill);

Then immediately after (in second query window):

USE master ALTER DATABASE <yourDbName> SET OFFLINE WITH ROLLBACK IMMEDIATE

Did what I needed and then brought it back online. Thanks to all who wrote these pieces out for me to combine and solve my problem.

Here is the complete code

#include <bits/stdc++.h>

using namespace std;

typedef unsigned char BYTE;

int main() {
  //method 1;
  std::vector<BYTE> data = {'H','E','L','L','O','1','2','3'};
  //string constructor accepts only const char
  std::string s((const char*)&(data[0]), data.size());
  std::cout << s << std::endl;

  //method 2
  std::string s2(data.begin(),data.end());
  std::cout << s2 << std::endl;

  //method 3
  std::string s3(reinterpret_cast<char const*>(&data[0]), data.size()) ;
  std::cout << s3 << std::endl;
 
  return 0;
}

Try below:

<script type="text/javascript">

function resetPassword() {
   url: "submitForgotPassword.html?email="+fixEscape(Stringwith+char);
}
function fixEscape(str)
{
    return escape(str).replace( "+", "%2B" );
}
</script>

You can set a default option for the column in the migration

....
add_column :status, :string, :default => "P"
....

OR

You can use a callback, before_save

class Task < ActiveRecord::Base
  before_save :default_values
  def default_values
    self.status ||= 'P' # note self.status = 'P' if self.status.nil? might be safer (per @frontendbeauty)
  end
end

You can use Math.Round:

decimal rounded = Math.Round(2.22939393, 3); //Returns 2.229

Or you can use ToString with the N3 numeric format.

string roundedNumber = number.ToString("N3");

EDIT: Since you don't want rounding, you can easily use Math.Truncate:

Math.Truncate(2.22977777 * 1000) / 1000; //Returns 2.229

The distance between two geo-coordinates can be found by using Haversine formula . This formula is effective to calculate distance in a spherical body i.e earth in our case.

It can even be made dependent to another attribute changes. like this:

$('.classA').toggleClass('classB', $('input').prop('disabled'));

In this case, classB are added each time the input is disabled

To get the whole row containing the max date for the user:

select username, date, value
from tablename where (username, date) in (
    select username, max(date) as date
    from tablename
    group by username
)

Kotlin Extension Properties

No file will be create when you make a File object, it is only an interface.

To make working with files easier, there is an existing .toFile function on Uri

You can also add an extension property on File and/or Uri, to simplify usage further.

val File?.exists get() = this?.exists() ?: false
val Uri?.exists get() = File(this.toString).exists()

Then just use uri.exists or file.exists to check.

phpMyAdmin provides a GUI for this within the structure view of a table. Check to select the column you want to move and click the change action at the bottom of the column list. You can then change all of the column properties and you'll find the 'move column' function at the far right of the screen.

Of course this is all just building the queries in the perfectly good top answer but GUI fans might appreciate the alternative.

my phpMyAdmin version is 4.1.7

If you use bower.json file to specify your dependencies:

{
     "dependencies": {
         ...
         "photo-swipe": "[email protected]:dimsemenov/PhotoSwipe.git#v3.0.x",

#bower 1.4 (tested with that version) can read repositorios with uri format

         "photo-swipe": "git://github.com/dimsemenov/PhotoSwipe.git#v3.0.x",

     }
}

Just remember bower also searches for released versions and tags so you can point to almost everything, and can interprate basic query patterns like previous example. that will fetch latest minor update of version 3.0 (tested from bower 1.3.5)

Update, as the question description also mention using only a URL and no mention of a github repository.

Another example is to execute this command using the desired url, like:

bower install gmap3MarkerWithLabel=http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.0/src/markerwithlabel.js -S

that command downloads your js library puts in {your destination path}/gmap3MarkerWithLabel/index.js and automatically creates an entry in your bower.json file called gmap3MarkerWithLabel: "..." After that, you can only execute bower update gmap3MarkerWithLabel if needed.

Funny thing if you do the process backwars (add manually the entry in bower.json, an then bower install entryName) it doesn't work, you get a

bower ENOTFOUND Package gmapV3MarkerWithLabel not found

date_default_timezone_set('Asia/Kolkata');

$curDateTime = date("Y-m-d H:i:s");
$myDate = date("Y-m-d H:i:s", strtotime("2018-06-26 16:15:33"));
if($myDate < $curDateTime){
    echo "active";exit;
}else{
    echo "inactive";exit;
}

@OP it doesn't matter, you can just split on a space with explode. Until you want to use those values, iterate over the exploded values and discard blanks.

$str = "A      B      C      D";
$s = explode(" ",$str);
foreach ($s as $a=>$b){    
    if ( trim($b) ) {
     print "using $b\n";
    }
}

@balusC I did as you wrote . In my case , I've added cookie information to be able to reuse the session .

   // get the cookie if need
    String cookies = conn.getHeaderField("Set-Cookie");

    // open the new connnection again
    conn = (HttpURLConnection) new URL(newUrl).openConnection();
    conn.setRequestProperty("Cookie", cookies);

As an addition to the solution:

ul li:before {
 content: '?'; 
}

You can use any SVG icon as the content, such as the Font Aswesome.

ul {_x000D_
  list-style: none;_x000D_
  padding-left: 0;_x000D_
}_x000D_
li {_x000D_
  position: relative;_x000D_
  padding-left: 1.5em;  /* space to preserve indentation on wrap */_x000D_
}_x000D_
li:before {_x000D_
  content: '';  /* placeholder for the SVG */_x000D_
  position: absolute;_x000D_
  left: 0;  /* place the SVG at the start of the padding */_x000D_
  width: 1em;_x000D_
  height: 1em;_x000D_
  background: url("data:image/svg+xml;utf8,<?xml version='1.0' encoding='utf-8'?><svg width='18' height='18' viewBox='0 0 1792 1792' xmlns='http://www.w3.org/2000/svg'><path d='M1671 566q0 40-28 68l-724 724-136 136q-28 28-68 28t-68-28l-136-136-362-362q-28-28-28-68t28-68l136-136q28-28 68-28t68 28l294 295 656-657q28-28 68-28t68 28l136 136q28 28 28 68z'/></svg>") no-repeat;_x000D_
}

<ul>_x000D_
  <li>this is my text</li>_x000D_
  <li>this is my text</li>_x000D_
  <li>This is my text, it's pretty long so it needs to wrap. Note that wrapping preserves the indentation that bullets had!</li>_x000D_
  <li>this is my text</li>_x000D_
  <li>this is my text</li>_x000D_
</ul>

Note: To solve the wrapping problem that other answers had:

• we reserve 1.5m ems of space at the left of each <li>
• then position the SVG at the start of that space (position: absolute; left: 0)

Here are more Font Awesome black icons.

Check this CODEPEN to see how you can add colors and change their size.

In terminal type :

netstat -anp|grep "port_number"

It will show the port details. Go to last column. It will be in this format . For example :- PID/java

then execute :

kill -9 PID. Worked on Centos5

For MAC:

lsof -n -i :'port-number' | grep LISTEN

Sample Response :

java   4744 (PID)  test  364u  IP0 asdasdasda   0t0  TCP *:port-number (LISTEN)

and then execute :

kill -9 PID 

Worked on Macbook

Personally i prefer the format function, allows you to simply change the date part very easily.

     declare @format varchar(100) = 'yyyy/MM/dd'
     select 
        format(the_date,@format), 
        sum(myfield) 
     from mytable 
     group by format(the_date,@format) 
     order by format(the_date,@format) desc;

The PHP way of doing this is simple:

$out = strlen($in) > 50 ? substr($in,0,50)."..." : $in;

But you can achieve a much nicer effect with this CSS:

.ellipsis {
    overflow: hidden;
    white-space: nowrap;
    text-overflow: ellipsis;
}

Now, assuming the element has a fixed width, the browser will automatically break off and add the ... for you.

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

Source: MSDN: Understanding Files and Filegroups

The recommended file name extension for secondary data files is .ndf, but this is not enforced.

Since the class is added dynamically, you need to use event delegation to register the event handler like:

$('#LangTable').on('click', '.deletelanguage', function(event) {
    event.preventDefault();
    alert("success");
});

This will attach your event to any anchors within the #LangTable element, reducing the scope of having to check the whole document element tree and increasing efficiency.

FIDDLE DEMO

There is a package called yum-utils that builds on YUM and contains a tool called repoquery that can do this.

$ repoquery --help | grep -E "list\ files" 
  -l, --list            list files in this package/group

Combined into one example:

$ repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

On at least one RH system, with rpm v4.8.0, yum v3.2.29, and repoquery v0.0.11, repoquery -l rpm prints nothing.

If you are having this issue, try adding the --installed flag: repoquery --installed -l rpm.

DNF Update:

To use dnf instead of yum-utils, use the following command:

$ dnf repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

java.exe is associated with the console, whereas javaw.exe doesn't have any such association. So, when java.exe is run, it automatically opens a command prompt window where output and error streams are shown.

Suppose your dt has columns col1, col2, col3, col4, col5, coln.

To delete a subset of them:

vx <- as.character(bquote(c(col1, col2, col3, coln)))[-1]
DT[, paste0(vx):=NULL]

You only need <script></script> Tag that's it. <script type="text/javascript"></script> is not a valid HTML tag, so for best SEO practice use <script></script>

Observation : When you call static method within a static entity, you need to change the class in @PrepareForTest.

For e.g. :

securityAlgo = MessageDigest.getInstance(SECURITY_ALGORITHM);

For the above code if you need to mock MessageDigest class, use

@PrepareForTest(MessageDigest.class)

While if you have something like below :

public class CustomObjectRule {

    object = DatatypeConverter.printHexBinary(MessageDigest.getInstance(SECURITY_ALGORITHM)
             .digest(message.getBytes(ENCODING)));

}

then, you'd need to prepare the class this code resides in.

@PrepareForTest(CustomObjectRule.class)

And then mock the method :

PowerMockito.mockStatic(MessageDigest.class);
PowerMockito.when(MessageDigest.getInstance(Mockito.anyString()))
      .thenThrow(new RuntimeException());

The only other way I can think of to do it is to enclose each of the rows you need a border around in a nested table. That will make the border easier to do but will potentially creat other layout issues, you'll have to manually set the width on table cells etc.

Your approach may well be the best one depending on your other layout rerquirements and the suggested approach here is just a possible alternative.

<table cellspacing="0">  
    <tr>    
        <td>no border</td>    
        <td>no border here either</td>  
    </tr>  
    <tr>
        <td>
             <table style="border: thin solid black">
                  <tr>    
                        <td>one</td>    
                        <td>two</td>  
                  </tr>  
                  <tr>    
                      <td>three</td>    
                      <td>four</td>  
                  </tr>  
             </table>
         </td>
    </tr>
    <tr>    
         <td colspan="2">once again no borders</td>  
    </tr>  
    <tr>
        <td>
             <table style="border: thin solid black">
                  <tr>    
                        <td>hello</td>  
                   </tr>
             </table>
         </td>
    </tr>
    <tr>    
         <td colspan="2">world</td>  
    </tr>
</table>

The whole reason you have a special Interface type-category in addition to abstract base classes in C#/Java is because C#/Java do not support multiple inheritance.

C++ supports multiple inheritance, and so a special type isn't needed. An abstract base class with no non-abstract (pure virtual) methods is functionally equivalent to a C#/Java interface.

You do not have Gemfile in a directory where you run that command. Gemfile is a file containing your gem settings for a current program.

You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.

perhaps a:

i=2
while i < n:
    if something:
       do something
       i += 1
    else: 
       do something else  
       i = 2 #restart the loop  

You can also use constants instead of strings to specify the mode you want. The benefit is if you make a typo in a constant name, your program will raise an runtime exception.

The constants are File::RDONLY or File::WRONLY or File::CREAT. You can also combine them if you like.

You can skip the ORM, builders, etc. and simplify your DB/SQL management using sqler and sqler-mdb.

• Format Document (Ctrl+K,Ctrl+D) so type Ctrl+K, AND THEN Ctrl+D as it is a sequence
• Format Selection (Ctrl+K,Ctrl+F)

Toolbar Edit -> Advanced (If you can't see Advanced, select a code file in solution explorer and try again)

Your shortcuts might display differently to mine as I am set up for C# coding but navigating via the toolbar will get you to your ones.

If it isn't working, look for errors in your code, like missing brackets which stop auto format from working

You have to add parameters since it is needed for the SP to execute

using (SqlConnection con = new SqlConnection(dc.Con))
{
    using (SqlCommand cmd = new SqlCommand("SP_ADD", con))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@FirstName", txtfirstname.Text);
        cmd.Parameters.AddWithValue("@LastName", txtlastname.Text);
        con.Open();
        cmd.ExecuteNonQuery();
    }            
}

I had the same error due to a typo in the service name, i was trying to delete the service display name instead of the service name. Once I used the right service name it worked fine

I used ALTER DATABASE mydb DEFAULT COLLATE utf8_unicode_ci;, but didn't work.

In this query:

Select * from table1, table2 where table1.field = date_format(table2.field,'%H');

This work for me:

Select * from table1, table2 where concat(table1.field) = date_format(table2.field,'%H');

Yes, only a concat.

Try like this

select id,numbers_from,created_date,amount_numbers,SMS_text 
from Test_Table
where 
created_date <= '2013-12-04'

The above answer for webkit appearance worked, but the button still looked kind pale/dull compared to the browser on other devices/desktop. I also had to set opacity to full (ranges from 0 to 1)

-webkit-appearance:none;
opacity: 1

After setting the opacity, the button looked the same on all the different devices/emulator/desktop.

get sock opt may be somewhat useful, however, another way would to have a signal handler installed for SIGPIPE. Basically whenever you the socket connection breaks, the kernel will send a SIGPIPE signal to the process and then you can do the needful. But this still does not provide the solution for knowing the status of the connection. hope this helps.

to write properties file (Java) normally I use this in linux (mint and ubuntu distributions):

$ native2ascii filename.properties

For example:

$ cat test.properties 
first=Execução número um
second=Execução número dois

$ native2ascii test.properties 
first=Execu\u00e7\u00e3o n\u00famero um
second=Execu\u00e7\u00e3o n\u00famero dois

PS: I writed Execution number one/two in portugues to force special characters.

In my case, in first execution I received this message:

$ native2ascii teste.txt 
The program 'native2ascii' can be found in the following packages:
 * gcj-5-jdk
 * openjdk-8-jdk-headless
 * gcj-4.8-jdk
 * gcj-4.9-jdk
Try: sudo apt install <selected package>

When I installed the first option (gcj-5-jdk) the problem was finished.

I hope this help someone.

If you have Python installed (works with either Python 2 or Python 3):

To select one file (or line from an arbitrary command), use

ls -1 | python -c "import sys; import random; print(random.choice(sys.stdin.readlines()).rstrip())"

To select N files/lines, use (note N is at the end of the command, replace this by a number)

ls -1 | python -c "import sys; import random; print(''.join(random.sample(sys.stdin.readlines(), int(sys.argv[1]))).rstrip())" N

It's a reference to the current event object

Did you accept the fingerprint for your computer on the device ? When you attach your PC a prompt will be displayed on your phone/device to add this fingerprint/token and trust it.

I had this issue... It was the log that was huge. Logs are here :

/var/lib/docker/containers/<container id>/<container id>-json.log

You can manage this in the run command line or in the compose file. See there : Configure logging drivers

I personally added these 3 lines to my docker-compose.yml file :

my_container:
  logging:
    options:
      max-size: 10m

You can't apply a keypair to a running instance. You can only use the new keypair to launch a new instance.

For recovery, if it's an EBS boot AMI, you can stop it, make a snapshot of the volume. Create a new volume based on it. And be able to use it back to start the old instance, create a new image, or recover data.

Though data at ephemeral storage will be lost.

Due to the popularity of this question and answer, I wanted to capture the information in the link that Rodney posted on his comment.

Credit goes to Eric Hammond for this information.

Fixing Files on the Root EBS Volume of an EC2 Instance

You can examine and edit files on the root EBS volume on an EC2 instance even if you are in what you considered a disastrous situation like:

• You lost your ssh key or forgot your password
• You made a mistake editing the /etc/sudoers file and can no longer gain root access with sudo to fix it
• Your long running instance is hung for some reason, cannot be contacted, and fails to boot properly
• You need to recover files off of the instance but cannot get to it

On a physical computer sitting at your desk, you could simply boot the system with a CD or USB stick, mount the hard drive, check out and fix the files, then reboot the computer to be back in business.

A remote EC2 instance, however, seems distant and inaccessible when you are in one of these situations. Fortunately, AWS provides us with the power and flexibility to be able to recover a system like this, provided that we are running EBS boot instances and not instance-store.

The approach on EC2 is somewhat similar to the physical solution, but we’re going to move and mount the faulty “hard drive” (root EBS volume) to a different instance, fix it, then move it back.

In some situations, it might simply be easier to start a new EC2 instance and throw away the bad one, but if you really want to fix your files, here is the approach that has worked for many:

Setup

Identify the original instance (A) and volume that contains the broken root EBS volume with the files you want to view and edit.

instance_a=i-XXXXXXXX

volume=$(ec2-describe-instances $instance_a |
  egrep '^BLOCKDEVICE./dev/sda1' | cut -f3)

Identify the second EC2 instance (B) that you will use to fix the files on the original EBS volume. This instance must be running in the same availability zone as instance A so that it can have the EBS volume attached to it. If you don’t have an instance already running, start a temporary one.

instance_b=i-YYYYYYYY

Stop the broken instance A (waiting for it to come to a complete stop), detach the root EBS volume from the instance (waiting for it to be detached), then attach the volume to instance B on an unused device.

ec2-stop-instances $instance_a
ec2-detach-volume $volume
ec2-attach-volume --instance $instance_b --device /dev/sdj $volume

ssh to instance B and mount the volume so that you can access its file system.

ssh ...instance b...

sudo mkdir -p 000 /vol-a
sudo mount /dev/sdj /vol-a

Fix It

At this point your entire root file system from instance A is available for viewing and editing under /vol-a on instance B. For example, you may want to:

• Put the correct ssh keys in /vol-a/home/ubuntu/.ssh/authorized_keys
• Edit and fix /vol-a/etc/sudoers
• Look for error messages in /vol-a/var/log/syslog
• Copy important files out of /vol-a/…

Note: The uids on the two instances may not be identical, so take care if you are creating, editing, or copying files that belong to non-root users. For example, your mysql user on instance A may have the same UID as your postfix user on instance B which could cause problems if you chown files with one name and then move the volume back to A.

Wrap Up

After you are done and you are happy with the files under /vol-a, unmount the file system (still on instance-B):

sudo umount /vol-a
sudo rmdir /vol-a

Now, back on your system with ec2-api-tools, continue moving the EBS volume back to it’s home on the original instance A and start the instance again:

ec2-detach-volume $volume

Hopefully, you fixed the problem, instance A comes up just fine, and you can accomplish what you originally set out to do. If not, you may need to continue repeating these steps until you have it working.

Note: If you had an Elastic IP address assigned to instance A when you stopped it, you’ll need to reassociate it after starting it up again.

Remember! If your instance B was temporarily started just for this process, don’t forget to terminate it now.

If you installed from source, you can issue the following command:

sudo make uninstall

If you followed the instructions on https://github.com/nodejs/node/wiki to install to your $HOME/local/node, then you have to type the following before the line above:

./configure --prefix=$HOME/local/node

You can use something like this pseudo code:

request = System.Net.HttpWebRequest.Create(your url)
request.Method = WebRequestMethods.Http.Post

writer = New System.IO.StreamWriter(request.GetRequestStream())
writer.Write("your data")
writer.Close()

response = request.GetResponse()
reader = New System.IO.StreamReader(response.GetResponseStream())
responseText = reader.ReadToEnd

PDOStatement::getColumnMeta()

As Charle's mentioned, this is a statement method, meaning it fetches the column data from a prepared statement (query).

There's a Java project that uses JNA (so no native libraries to install) and is in active development. It currently supports Linux, OSX, Windows, Solaris and FreeBSD and provides RAM, CPU, Battery and file system information.

I got this error when running a query without SSL.

Simply changing the URL scheme of my request from HTTP to HTTPS fixed it.

In my case, issue was occured even after all these configurations have done (@Pekka has mentioned changes in httpd.conf & .htaccess files). It was resolved only after I add

<Directory "project/path">
  Order allow,deny
  Allow from all
  AllowOverride All
</Directory>

to virtual host configuration in vhost file

Arrays.asList(factors) returns a List<int[]>, not a List<Integer>. Since you're doing new ArrayList instead of new ArrayList<Integer> you don't get a compile error for that, but create an ArrayList<Object> which contains an int[] and you then implicitly cast that arraylist to ArrayList<Integer>. Of course the first time you try to use one of those "Integers" you get an exception.

I solved this. double click this error leads to behavior.

1. open .vcxproj file of your project
2. search for tag
3. check carefully what's going inside this tag, the path is right? difference between debug and release, and fix it
4. clean and rebuild

for my case. a miss match of debug and release mod kills my afternoon.

          <Command Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">copy ..\vc2005\%(Filename)%(Extension) ..\..\cvd\
</Command>
      <Command Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">copy ..\vc2005\%(Filename)%(Extension) ..\..\cvd\
</Command>
      <Outputs Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">..\..\cvd\%(Filename)%(Extension);%(Outputs)</Outputs>
      <Outputs Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">..\..\cvd\%(Filename)%(Extension);%(Outputs)</Outputs>

    </CustomBuild>

Assuming you have a properties file on your classpath that contains

api.orders.pingFrequency=4

I tried inside a @Controller

@Controller
public class MyController {     
    @Value("${api.orders.pingFrequency}")
    private Integer pingFrequency;
    ...
}

With my servlet context containing :

<context:property-placeholder location="classpath:myprops.properties" />

It worked perfectly.

So either your property is not an integer type, you don't have the property placeholder configured correctly, or you are using the wrong property key.

I tried running with an invalid property value, 4123;. The exception I got is

java.lang.NumberFormatException: For input string: "4123;"

which makes me think the value of your property is

api.orders.pingFrequency=(java.lang.Integer)${api.orders.pingFrequency}

Extending @endian 's answer, you could use a thread and call a method to update the TextView. Below is some code I made up on the spot.

java.util.Date noteTS;
String time, date;
TextView tvTime, tvDate;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.deskclock);

    tvTime = (TextView) findViewById(R.id.tvTime);
    tvDate = (TextView) findViewById(R.id.tvDate);

    Thread t = new Thread() {

        @Override
        public void run() {
            try {
                while (!isInterrupted()) {
                    Thread.sleep(1000);
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            updateTextView();
                        }
                    });
                }
            } catch (InterruptedException e) {
            }
        }
    };

    t.start();
}

private void updateTextView() {
    noteTS = Calendar.getInstance().getTime();

    String time = "hh:mm"; // 12:00
    tvTime.setText(DateFormat.format(time, noteTS));

    String date = "dd MMMMM yyyy"; // 01 January 2013
    tvDate.setText(DateFormat.format(date, noteTS));
}

In the Xcode 6.2, this also works

let appDelegate = UIApplication.sharedApplication().delegate! as AppDelegate

let aVariable = appDelegate.someVariable

jQuery.fn.make_me_red = function() {
    alert($(this).attr('id'));
    $(this).siblings("#hello").toggle();
}
$("#user_button").click(function(){
    //$(this).siblings(".hello").make_me_red(); 
    $(this).make_me_red(); 
    $(this).addClass("active");
});
?

Function declaration and callback in jQuery.

If animating opacity is not an option, you can also animate background-size.

For example, I used this CSS to set a backgound-image with a delay.

.before {
  background-size: 0;
}

.after {
  transition: background 0.1s step-end;
  background-image: $path-to-image;
  background-size: 20px 20px;
}

Here's a method which receives boundaries and returns a random integer. It is slightly more advanced (completely universal): boundaries can be both positive and negative, and minimum/maximum boundaries can come in any order.

int myRand(int i_from, int i_to) {
  return (int)(Math.random() * (Math.abs(i_from - i_to) + 1)) + Math.min(i_from, i_to);
}

In general, it finds the absolute distance between the borders, gets relevant random value, and then shifts the answer based on the bottom border.

For anyone looking to use this and keep the 'click' functionality (as John Landheer mentions in his comment), you can do it with just a couple of modifications:

Add a couple of globals:

var clickms = 100;
var lastTouchDown = -1;

Then modify the switch statement from the original to this:

var d = new Date();
switch(event.type)
{
    case "touchstart": type = "mousedown"; lastTouchDown = d.getTime(); break;
    case "touchmove": type="mousemove"; lastTouchDown = -1; break;        
    case "touchend": if(lastTouchDown > -1 && (d.getTime() - lastTouchDown) < clickms){lastTouchDown = -1; type="click"; break;} type="mouseup"; break;
    default: return;
}

You may want to adjust 'clickms' to your tastes. Basically it's just watching for a 'touchstart' followed quickly by a 'touchend' to simulate a click.

There are a few answers already, but here is my solution:

I use opacity: 0 and visibility: hidden. To make sure that visibility is set before the animation, we have to set the right delays.

I use http://lesshat.com to simplify the demo, for use without this just add the browser prefixes.

(e.g. -webkit-transition-duration: 0, 200ms;)

.fadeInOut {
    .transition-duration(0, 200ms);
    .transition-property(visibility, opacity);
    .transition-delay(0);

    &.hidden {
        visibility: hidden;
        .opacity(0);
        .transition-duration(200ms, 0);
        .transition-property(opacity, visibility);
        .transition-delay(0, 200ms);
    }
}

So as soon as you add the class hidden to your element, it will fade out.

You call both event listeners using .on() then use a if inside the function:

$(function(){
  $('#searchButton').on('keypress click', function(e){
    var search = $('#usersSearch').val();
    if (e.which === 13 || e.type === 'click') {
      $.post('../searchusers.php', {search: search}, function (response) {
        $('#userSearchResultsTable').html(response);
      });
    }
  });
});

I find that running

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

and

export VIRTUALENVWRAPPER_VIRTUALENV=/usr/bin/virtualenv-3.4

in the command line on Ubuntu forces mkvirtualenv to use python3 and virtualenv-3.4. One still has to do

mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment

to create the environment. This is assuming that you have python3 in /usr/bin/python3 and virtualenv-3.4 in /usr/local/bin/virtualenv-3.4.

Try to upgrade and install new packages

sudo apt-get update && sudo apt-get upgrade -y

You can use readlink on /proc/self/fd/NNN where NNN is the file descriptor. This will give you the name of the file as it was when it was opened — however, if the file was moved or deleted since then, it may no longer be accurate (although Linux can track renames in some cases). To verify, stat the filename given and fstat the fd you have, and make sure st_dev and st_ino are the same.

Of course, not all file descriptors refer to files, and for those you'll see some odd text strings, such as pipe:[1538488]. Since all of the real filenames will be absolute paths, you can determine which these are easily enough. Further, as others have noted, files can have multiple hardlinks pointing to them - this will only report the one it was opened with. If you want to find all names for a given file, you'll just have to traverse the entire filesystem.

I had the exact same problem you describe above (Galaxy Nexus on t-mobile USA) it is because mobile data is turned off.

In Jelly Bean it is: Settings > Data Usage > mobile data

Note that I have to have mobile data turned on PRIOR to sending an MMS OR receiving one. If I receive an MMS with mobile data turned off, I will get the notification of a new message and I will receive the message with a download button. But if I do not have mobile data on prior, the incoming MMS attachment will not be received. Even if I turn it on after the message was received.

For some reason when your phone provider enables you with the ability to send and receive MMS you must have the Mobile Data enabled, even if you are using Wifi, if the Mobile Data is enabled you will be able to receive and send MMS, even if Wifi is showing as your internet on your device.

It is a real pain, as if you do not have it on, the message can hang a lot, even when turning on Mobile Data, and might require a reboot of the device.

That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

Could you use jQuery, since it's cross-browser compatible?

function isOnScreen(element)
{
    var curPos = element.offset();
    var curTop = curPos.top;
    var screenHeight = $(window).height();
    return (curTop > screenHeight) ? false : true;
}

And then call the function using something like:

if(isOnScreen($('#myDivId'))) { /* Code here... */ };

awk '{print substr($0,6)}' file

I ended up packaging this into an extension method so (1) I could generate the label and radio at once and (2) so I didn't have to fuss with specifying my own IDs:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString RadioButtonAndLabelFor<TModel, TProperty>(this HtmlHelper<TModel> self, Expression<Func<TModel, TProperty>> expression, bool value, string labelText)
    {
        // Retrieve the qualified model identifier
        string name = ExpressionHelper.GetExpressionText(expression);
        string fullName = self.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(name);

        // Generate the base ID
        TagBuilder tagBuilder = new TagBuilder("input");
        tagBuilder.GenerateId(fullName);
        string idAttr = tagBuilder.Attributes["id"];

        // Create an ID specific to the boolean direction
        idAttr = String.Format("{0}_{1}", idAttr, value);

        // Create the individual HTML elements, using the generated ID
        MvcHtmlString radioButton = self.RadioButtonFor(expression, value, new { id = idAttr });
        MvcHtmlString label = self.Label(idAttr, labelText);

        return new MvcHtmlString(radioButton.ToHtmlString() + label.ToHtmlString());
    }
}

Usage:

@Html.RadioButtonAndLabelFor(m => m.IsMarried, true, "Yes, I am married")

Alternatively, consider using a document databases (such as MongoDB) which natively support rich data structures and nesting.

1. Install the Java SDK.

2. Add a System Environment Variable called JAVA_HOME with the value of JDK location.
   Go to Control Panel\System and Security\System. Advanced System Settings, Environment Variables, System Variables, New... Example:
   Variable Name:JAVA_HOME
   Variable Value: C:\Program Files\Java\jdk1.7.0_21

3. Close/reopen your CMD window so that the new variable takes effect before attempting to re-run the ant command.

There is a solution after reloading the page and keeping the expected tab as selected.

Suppose after saving data the redirected url is : my_url#tab_2

Now through the following script your expected tab will remain selected.

$(document).ready(function(){
    var url = document.location.toString();
    if (url.match('#')) {
        $('.nav-tabs a[href="#' + url.split('#')[1] + '"]').tab('show');
        $('.nav-tabs a').removeClass('active');
    }
});

Using standard JSF API, add the client ID to PartialViewContext#getRenderIds().

FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add("foo:bar");

Using PrimeFaces specific API, use PrimeFaces.Ajax#update().

PrimeFaces.current().ajax().update("foo:bar");

Or if you're not on PrimeFaces 6.2+ yet, use RequestContext#update().

RequestContext.getCurrentInstance().update("foo:bar");

If you happen to use JSF utility library OmniFaces, use Ajax#update().

Ajax.update("foo:bar");

Regardless of the way, note that those client IDs should represent absolute client IDs which are not prefixed with the NamingContainer separator character like as you would do from the view side on.

Try this out:

$url = 'http://techcrunch.com/startups/'; $url = str_replace(array('http://', 'https://'), '', $url); 

EDIT:

Or, a simple way to always remove the protocol:

$url = 'https://www.google.com/'; $url = preg_replace('@^.+?\:\/\/@', '', $url); 

CMD:

reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
reg query HKEY_CURRENT_USER\Environment

PowerShell:

Get-Item "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Get-Item HKCU:\Environment

Powershell/.NET: (see EnvironmentVariableTarget Enum)

[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::Machine)
[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::User)

What if I told you, it depends?

I in general initialize everything and do it in a consistent way. Yes it's overly explicit but it's also a little easier to maintain.

If we are worried about performance, well then I initialize only what has to be done and place it in the areas it gives the most bang for the buck.

In a real time system, I question if I even need the variable or constant at all.

And in C++ I often do next to no initialization in either place and move it into an Init() function. Why? Well, in C++ if you're initializing something that can throw an exception during object construction you open yourself to memory leaks.

It seems to be a browser bug.

10690: Reported a bug in Firefox for responsive images (those with max-width: 100%) in table cells. No other browsers are affected. See

.img-responsive in <fieldset> have the same behaviour.

You can use a data: URL to embed a Base64 encoded version of an image. But it's not very efficient and wouldn't recommend embedding large images. Any reason linking to another file is not feasible?

Googled this ("html5 canvas paint program"). Looks like what you need.

http://dev.opera.com/articles/view/html5-canvas-painting/

I would have a directory somewhere called scripts under the WWW folder so that it's not reachable from the web but is reachable by PHP.

e.g. /var/www/scripts/testscript

Make sure the user/group for your testscript is the same as your webfiles. For instance if your client.php is owned by apache:apache, change the bash script to the same user/group using chown. You can find out what your client.php and web files are owned by doing ls -al.

Then run

<?php
      $message=shell_exec("/var/www/scripts/testscript 2>&1");
      print_r($message);
    ?>  

EDIT:

If you really want to run a file as root from a webserver you can try this binary wrapper below. Check out this solution for the same thing you want to do.

Execute root commands via PHP

I am sharing our nodejs implementation of the solution as implemented by @Raymond Hettinger.

var crypto = require('crypto');
var s = 'she sells sea shells by the sea shore';
console.log(BigInt('0x' + crypto.createHash('sha1').update(s).digest('hex'))%(10n ** 8n));

This feature has been added in dplyr v0.3. You can now pass a named character vector to the by argument in left_join (and other joining functions) to specify which columns to join on in each data frame. With the example given in the original question, the code would be:

left_join(test_data, kantrowitz, by = c("first_name" = "name"))

This is very nice:

http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/RandomStringUtils.html - something like RandomStringUtils.randomNumeric(7).

There are 10^7 equiprobable (if java.util.Random is not broken) distinct values so uniqueness may be a concern.

We also can archive the folder /var/lib/docker/overlay2/ to compare the size of the package to image files. The size is close to the image size either.

With newer Go versions, reading/writing to/from file is easy. To read from a file:

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    data, err := ioutil.ReadFile("text.txt")
    if err != nil {
        return
    }
    fmt.Println(string(data))
}

To write to a file:

package main

import "os"

func main() {
    file, err := os.Create("text.txt")
    if err != nil {
        return
    }
    defer file.Close()

    file.WriteString("test\nhello")
}

This will overwrite the content of a file (create a new file if it was not there).

java.time

I am providing the modern answer. The Timestamp class is a hack on top of the already poorly designed java.util.Date class and is long outdated. I am assuming, though, that you are getting a Timestamp from a legacy API that you cannot afford to upgrade to java.time just now. When you do that, convert it to a modern Instant and do further processing from there.

    DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.MEDIUM)
            .withLocale(Locale.GERMAN);
    
    Timestamp oldfashionedTimestamp = new Timestamp(1_567_890_123_456L);
    
    ZonedDateTime dateTime = oldfashionedTimestamp.toInstant()
            .atZone(ZoneId.systemDefault());
    String desiredFormat = dateTime.format(formatter);
    
    System.out.println(desiredFormat);

Output in my time zone:

07.09.2019 23:02:03

Pick how long or short of a format you want by specifying FormatStyle.SHORT, .MEDIUM, .LONG or .FULL. Pick your own locale where I put Locale.GERMAN. And pick your desired time zone, for example ZoneId.of("Europe/Oslo"). A Timestamp is a point in time without time zone, so we need a time zone to be able to convert it into year, month, day, hour, minute, etc. If your Timestamp comes from a database value of type timestamp without time zone (generally not recommended, but unfortunately often seen), ZoneId.systemDefault() is likely to give you the correct result. Another and slightly simpler option in this case is instead to convert to a LocalDateTime using oldfashionedTimestamp.toLocalDateTime() and then format the LocalDateTime in the same way as I did with the ZonedDateTime.

Use AddWithValue(), but be aware of the possibility of the wrong implicit type conversion.
like this:

cmd.Parameters.AddWithValue("@param1", klantId);
    cmd.Parameters.AddWithValue("@param2", klantNaam);
    cmd.Parameters.AddWithValue("@param3", klantVoornaam);

For people that find this question by searching for the error message, you can also see this error if you make a mistake in your @JsonProperty annotations such that you annotate a List-typed property with the name of a single-valued field:

@JsonProperty("someSingleValuedField") // Oops, should have been "someMultiValuedField"
public List<String> getMyField() { // deserialization fails - single value into List
  return myField;
}

The following solution works well when you want to move the text closer to the bullet and even if you have multiple lines of text.

margin-right allows you to move the text closer to the bullet

text-indent ensures that multiple lines of text still line up correctly

li:before {_x000D_
  content: "";_x000D_
  margin-right: -5px; /* Adjust this to move text closer to the bullet */_x000D_
}_x000D_
_x000D_
li {_x000D_
  text-indent: 5px; /* Aligns second line of text */_x000D_
}

<ul>_x000D_
  <li> Item 1 ... </li>_x000D_
  <li> Item 2 ... this item has tons and tons of text that causes a second line! Notice how even the second line is lined up with the first!</li>_x000D_
  <li> Item 3 ... </li>_x000D_
</ul>

Set level to OFF (instead of DEBUG, INFO, ....)

To convert the string into a date object:

from datetime import date, datetime

date_string = "01/12/2011"
date_object = date(*map(int, reversed(date_string.split("/"))))
assert date_object == datetime.strptime(date_string, "%d/%m/%Y").date()

The way to convert the date object into POSIX timestamp depends on timezone. From Converting datetime.date to UTC timestamp in Python:

• date object represents midnight in UTC

  import calendar
  
  timestamp1 = calendar.timegm(utc_date.timetuple())
  timestamp2 = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * 24*60*60
  assert timestamp1 == timestamp2
  

• date object represents midnight in local time

  import time
  
  timestamp3 = time.mktime(local_date.timetuple())
  assert timestamp3 != timestamp1 or (time.gmtime() == time.localtime())
  

The timestamps are different unless midnight in UTC and in local time is the same time instance.

Use the View for your efforts in altering the position of the column: CREATE VIEW CORRECTED_POSITION AS SELECT co1_1, col_3, col_2 FROM UNORDERDED_POSITION should help.

This requests are made so some reports get produced where it is using SELECT * FROM [table_name]. Or, some business has a hierarchy approach of placing the information in order for better readability from the back end.

Here is a perfect way to split the video. I have done it previously, and it's working well for me.

ffmpeg -i C:\xampp\htdocs\videoCutting\movie.mp4 -ss 00:00:00 -t 00:00:05 -async 1 C:\xampp\htdocs\videoCutting\SampleVideoNew.mp4 (For cmd). shell_exec('ffmpeg -i C:\xampp\htdocs\videoCutting\movie.mp4 -ss 00:00:00 -t 00:00:05 -async 1 C:\xampp\htdocs\videoCutting\SampleVideoNew.mp4') (for php).

Please follow this and I am sure it will work perfectly.

One common way is to add the image to a QLabel widget using QLabel::setPixmap(), and then display the QLabel as you would any other widget. Example:

#include <QtGui>

int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  QPixmap pm("your-image.jpg");
  QLabel lbl;
  lbl.setPixmap(pm);
  lbl.show();
  return app.exec();
}

If you are using SQL Server 2005 or greater, depending on the size of the data in the Notes field, you may want to consider casting to nvarchar(max) instead of casting to a specific length which could result in string truncation.

Select Cast(notes as nvarchar(max)) + 'SomeText' From NotesTable a

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

Following the documentation of fopen:

``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.

So if you pFile2=fopen("myfile2.txt", "a"); the stream is positioned at the end to append automatically. just do:

FILE *pFile;
FILE *pFile2;
char buffer[256];

pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
    perror("Error opening file.");
}
else {
    while(fgets(buffer, sizeof(buffer), pFile)) {
        fprintf(pFile2, "%s", buffer);
    }
}
fclose(pFile);
fclose(pFile2);

I know when you said "contents" you didn't mean this, but if you want to find all the values of all the attributes of a webelement this is a pretty nifty way to do that with javascript in python:

everything = b.execute_script(
    'var element = arguments[0];'
    'var attributes = {};'
    'for (index = 0; index < element.attributes.length; ++index) {'
    '    attributes[element.attributes[index].name] = element.attributes[index].value };'
    'var properties = [];'
    'properties[0] = attributes;'
    'var element_text = element.textContent;'
    'properties[1] = element_text;'
    'var styles = getComputedStyle(element);'
    'var computed_styles = {};'
    'for (index = 0; index < styles.length; ++index) {'
    '    var value_ = styles.getPropertyValue(styles[index]);'
    '    computed_styles[styles[index]] = value_ };'
    'properties[2] = computed_styles;'
    'return properties;', element)

you can also get some extra data with element.__dict__.

I think this is about all the data you'd ever want to get from a webelement.

if ( $profitloss < 0 ) {
   echo "negative";
};

For those who still have problems after attempting the suggestions above: I solved the issue by updating the maven project.

Try this below code

<?php
$file = 'dummy.pdf';
$filename = 'dummy.pdf';
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
header('Accept-Ranges: bytes');
@readfile($file);
?>

Demo

The answer here is very simple:

You're already containing it in double quotes, so there's no need to escape it with \.

If you want to escape single quotes in a single quote string:

var string = 'this isn\'t a double quoted string';
var string = "this isn\"t a single quoted string";
//           ^         ^ same types, hence we need to escape it with a backslash

or if you want to escape \', you can escape the bashslash to \\ and the quote to \' like so:

var string = 'this isn\\\'t a double quoted string';
//                    vvvv
//                     \ ' (the escaped characters)

However, if you contain the string with a different quote type, you don't need to escape:

var string = 'this isn"t a double quoted string';
var string = "this isn't a single quoted string";
//           ^        ^ different types, hence we don't need escaping

Try this is working great with me.

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

To read a file — one byte at a time (ignoring the buffering) — you could use the two-argument iter(callable, sentinel) built-in function:

with open(filename, 'rb') as file:
    for byte in iter(lambda: file.read(1), b''):
        # Do stuff with byte

It calls file.read(1) until it returns nothing b'' (empty bytestring). The memory doesn't grow unlimited for large files. You could pass buffering=0 to open(), to disable the buffering — it guarantees that only one byte is read per iteration (slow).

with-statement closes the file automatically — including the case when the code underneath raises an exception.

Despite the presence of internal buffering by default, it is still inefficient to process one byte at a time. For example, here's the blackhole.py utility that eats everything it is given:

#!/usr/bin/env python3
"""Discard all input. `cat > /dev/null` analog."""
import sys
from functools import partial
from collections import deque

chunksize = int(sys.argv[1]) if len(sys.argv) > 1 else (1 << 15)
deque(iter(partial(sys.stdin.detach().read, chunksize), b''), maxlen=0)

Example:

$ dd if=/dev/zero bs=1M count=1000 | python3 blackhole.py

It processes ~1.5 GB/s when chunksize == 32768 on my machine and only ~7.5 MB/s when chunksize == 1. That is, it is 200 times slower to read one byte at a time. Take it into account if you can rewrite your processing to use more than one byte at a time and if you need performance.

mmap allows you to treat a file as a bytearray and a file object simultaneously. It can serve as an alternative to loading the whole file in memory if you need access both interfaces. In particular, you can iterate one byte at a time over a memory-mapped file just using a plain for-loop:

from mmap import ACCESS_READ, mmap

with open(filename, 'rb', 0) as f, mmap(f.fileno(), 0, access=ACCESS_READ) as s:
    for byte in s: # length is equal to the current file size
        # Do stuff with byte

mmap supports the slice notation. For example, mm[i:i+len] returns len bytes from the file starting at position i. The context manager protocol is not supported before Python 3.2; you need to call mm.close() explicitly in this case. Iterating over each byte using mmap consumes more memory than file.read(1), but mmap is an order of magnitude faster.

If you like to keep it fixed width, for example 10 digits, do it like this

Key = i.ToString("0000000000");

Replace with as many digits as you like.

i = 123 will then result in Key = "0000000123".

Okay here some more complex sample for the use of For /F

:: Main
@prompt -$G
    call :REGQUERY  "Software\Classes\CLSID\{3E6AE265-3382-A429-56D1-BB2B4D1D}"

@goto :EOF

:REGQUERY
:: Checks HKEY_LOCAL_MACHINE\ and HKEY_CURRENT_USER\ 
:: for the key and lists its content

    @call :EXEC "REG QUERY  HKCU\%~1"
    @call :EXEC "REG QUERY "HKLM\%~1""

@goto :EOF    

:EXEC
    @set output=

    @for /F "delims=" %%i in ('%~1 2^>nul') do @(
        set output=%%i
    )

    @if not "%output%"=="" (
        echo %1 -^> %output%
    )

@goto :EOF

I packed it into the sub function :EXEC so all of its nasty details of implementation doesn't litters the main script. So it got some kinda some batch tutorial. Notes 'bout the code:

1. the output from the command executed via call :EXEC command is stored in %output%. Batch cmd doesn't cares about scopes so %output% will be also available in the main script.
2. the @ the beginning is just decoration and there to suppress echoing the command line. You may delete them all and just put some @echo off at the first line is really dislike that. However like this I find debugging much more nice. Decoration Number two is prompt -$G. It's there to make command prompt look like this ->
3. I use :: instead of rem
4. the tilde(~) in %~1 is to remove quotes from the first argument
5. 2^>nul is there to suppress/discard stderr error output. Normally you would do it via 2>nul. Well the ^ the batch escape char is there avoids to early resolving the redirector(>). There's some simulare use a little later in the script: echo %1 -^>... so there ^ makes it possible the output a '>' via echo what else wouldn't have been possible.
6. even if the compare at @if not "%output%"==""looks like in most common programming languages - it's maybe different that you expected (if you're not used to MS-batch). Well remove the '@' at the beginning. Study the output. Change it tonot %output%==""-rerun and consider why this doesn't work. ;)

application because .js-Files aren't something a user wants to read but something that should get executed.

SOLVED
After banging my head on the wall for a couple days with this issue, it was looking like the problem had something to do with the content type negotiation between the client and server. I dug deeper into that using Fiddler to check the request details coming from the client app, here's a screenshot of the raw request as captured by fiddler:

What's obviously missing there is the Content-Type header, even though I was setting it as seen in the code sample in my original post. I thought it was strange that the Content-Type never came through even though I was setting it, so I had another look at my other (working) code calling a different Web API service, the only difference was that I happened to be setting the req.ContentType property prior to writing to the request body in that case. I made that change to this new code and that did it, the Content-Type was now showing up and I got the expected success response from the web service. The new code from my .NET client now looks like this:

req.Method = "POST"
req.ContentType = "application/json"
lstrPagingJSON = JsonSerializer(Of Paging)(lPaging)
bytData = Encoding.UTF8.GetBytes(lstrPagingJSON)
req.ContentLength = bytData.Length
reqStream = req.GetRequestStream()
reqStream.Write(bytData, 0, bytData.Length)
reqStream.Close()
'// Content-Type was being set here, causing the problem
'req.ContentType = "application/json"

That's all it was, the ContentType property just needed to be set prior to writing to the request body

I believe this behavior is because once content is written to the body it is streamed to the service endpoint being called, any other attributes pertaining to the request need to be set prior to that. Please correct me if I'm wrong or if this needs more detail.

@AlexanderMP's answer is correct, but you can also consider handling nulls with coalesce:

declare @CodeNameString  nvarchar(max)
set @CodeNameString = null
SELECT @CodeNameString = Coalesce(@CodeNameString + ', ', '') + cast(CodeName as varchar) from AccountCodes  
select @CodeNameString

After finding this StackOverflow question/answer

Complex type is getting null in a ApiController parameter

the [FromBody] attribute on the controller method needs to be [FromUri] since a GET does not have a body. After this change the "filter" complex object is passed correctly.

You may have select option values such as "Choose option". If you want to keep that value and clear the rest of the values you can first remove all the values and append "Choose Option"

<select multiple='multiple' id='selectName'> 
    <option selected disabled>Choose Option</option>
    <option>1</option> 
    <option>2</option> 
    <option>3</option>    
</select>

Jquery

$('#selectName option').remove(); // clear all values 
$('#selectName ').append('<option selected disabled>Choose Option</option>'); //append what you want to keep

When you need to do it in a string (eg: in your resources) you need to use xml:space="preserve" and the ampersand character codes:

<System:String x:Key="TwoLiner" xml:space="preserve">First line&#10;Second line</System:String>

Or literal newlines in the text:

<System:String x:Key="TwoLiner" xml:space="preserve">First line 
Second line</System:String>

Warning: if you write code like the second example, you have inserted either a newline, or a carriage return and newline, depending on the line endings your operating system and/or text editor use. For instance, if you write that and commit it to git from a linux systems, everything may seem fine -- but if someone clones it to Windows, git will convert your line endings to \r\n and depending on what your string is for ... you might break the world.

Just be aware of that when you're preserving whitespace. If you write something like this:

<System:String x:Key="TwoLiner" xml:space="preserve">
First line 
Second line 
</System:String>

You've actually added four line breaks, possibly four carriage-returns, and potentially trailing white space that's invisible...

Take attention on -e ssh and jenkins@localhost: in next example:

rsync -r  -e ssh --chown=jenkins:admin --exclude .git --exclude Jenkinsfile --delete ./ jenkins@localhost:/home/admin/web/xxx/public

That helped me

P.S. Today, i realized that when you change (add) jenkins user to some group, permission will apply after slave (agent) restart. And my solution (-e ssh and jenkins@localhost:) need only when you can't restart agent/server.

In my case, I was missing something really trivial.

<input value={state.myObject.inputValue} />

My state was the following when I was getting the warning:

state = {
   myObject: undefined
}

By alternating my state to reference the input of my value, my issue was solved:

state = {
   myObject: {
      inputValue: ''
   }
}

Some things to watch out for:

• As you mentioned, su will prompt for a password if you are already the target user
• Similarly, setuid(2) will fail if you are already the target user (on some OSs)
• setuid(2) does not install privileges or resource controls defined in /etc/limits.conf (Linux) or /etc/user_attr (Solaris)
• If you go the setgid(2)/setuid(2) route, don't forget to call initgroups(3) -- more on this here

I generally use /sbin/su to switch to the appropriate user before starting daemons.

In postgresql if you want to insert values with ' in it then for this you have to give extra '

 insert into test values (1,'user''s log');
 insert into test values (2,'''my users''');
 insert into test values (3,'customer''s');

In some websites, XMLHttpRequest may send you something like <script src="#"></srcipt>. In that case, try using a HTML document like the script under:

<html>
  <body>
    <iframe src="website.com"></iframe>
    <script src="your_JS"></script>
  </body>
</html>

Now you can use JS to get some text out of the HTML, such as getElementbyId.

But this may not work for some websites with cross-domain blocking.

You can use down-stepping to achieve better results. Most browsers seem to use linear interpolation rather than bi-cubic when resizing images.

(Update There has been added a quality property to the specs, imageSmoothingQuality which is currently available in Chrome only.)

Unless one chooses no smoothing or nearest neighbor the browser will always interpolate the image after down-scaling it as this function as a low-pass filter to avoid aliasing.

Bi-linear uses 2x2 pixels to do the interpolation while bi-cubic uses 4x4 so by doing it in steps you can get close to bi-cubic result while using bi-linear interpolation as seen in the resulting images.

    oc.height = img.height * 0.5;_x000D_
    octx.drawImage(img, 0, 0, oc.width, oc.height);_x000D_
_x000D_
    // step 2_x000D_
    octx.drawImage(oc, 0, 0, oc.width * 0.5, oc.height * 0.5);_x000D_
_x000D_
    // step 3, resize to final size_x000D_
    ctx.drawImage(oc, 0, 0, oc.width * 0.5, oc.height * 0.5,_x000D_
    0, 0, canvas.width, canvas.height);_x000D_
}_x000D_
img.src = "//i.imgur.com/SHo6Fub.jpg";

<img src="//i.imgur.com/SHo6Fub.jpg" width="300" height="234">_x000D_
<canvas id="canvas" width=300></canvas>

Depending on how drastic your resize is you can might skip step 2 if the difference is less.

In the demo you can see the new result is now much similar to the image element.

It absolutely depens on what your goals are. The Bugzilla and Trac systems mentioned are nice but geared towards bug tracking, which is just very different from a tool you'd want to use in a helpdesk-type setup where end users would raise incidents.

If the latter is what you are looking for I'd suggest you take a look at OTRS which is a very capable trouble ticketing system. It also has ITSM extensions, which makes it able to support ITIL processes if you need to.

Here is example of pseudo-random generator when neither $RANDOM nor /dev/urandom is available

echo $(date +%S) | grep -o .$ | sed s/0/10/

Not Bootstrap specific really... You can use inline styles or define a custom class to specify the desired "background-color".

On the other hand, Bootstrap does have a few built in background colors that have semantic meaning like "bg-success" (green) and "bg-danger" (red).

Refer to following links:

1. http://developer.android.com/reference/android/os/AsyncTask.html
2. http://labs.makemachine.net/2010/05/android-asynctask-example/

You cannot pass more than three arguments, if you want to pass only 1 argument then use void for the other two arguments.

1. private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> 


2. protected class InitTask extends AsyncTask<Context, Integer, Integer>

An asynchronous task is defined by a computation that runs on a background thread and whose result is published on the UI thread. An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute.

You could use Super Pdf2Image Converter to generate a TIFF multi-page file with all the rendered pages from the PDF in high resolution. It's available for both 32 and 64 bit and is very cheap and effective. I'd recommend you to try it.

Just one line of code...

GetImage(outputFileName, firstPage, lastPage, resolution, imageFormat)

Converts specifies pages to image and save them to outputFileName (tiff allows multi-page or creates several files)

You can take a look here: http://softwaresigloxxi.com/SuperPdf2ImageConverter.html

An alternative to the many solutions already provided is making use of the glob **. When you use bash with the option globstar (shopt -s globstar) or you make use of zsh, you can just use the glob ** for this.

**/bar

does a recursive directory search for files named bar (potentially including the file bar in the current directory). Remark that this cannot be combined with other forms of globbing within the same path segment; in that case, the * operators revert to their usual effect.

Note that there is a subtle difference between zsh and bash here. While bash will traverse soft-links to directories, zsh will not. For this you have to use the glob ***/ in zsh.

Looking at the current answers I feel that one easy and clean fix is missing. Just in case someone passes by and looks for the right solution. I am quite successful with some simple CSS and javascript.

Center canvas to middle of the screen or parent element. No wrapping.

HTML:

<canvas id="canvas" width="400" height="300">No canvas support</canvas>

CSS:

#canvas {
    position: absolute;
    top:0;
    bottom: 0;
    left: 0;
    right: 0;
    margin:auto;
}

Javascript:

window.onload = window.onresize = function() {
    var canvas = document.getElementById('canvas');
    canvas.width = window.innerWidth * 0.8;
    canvas.height = window.innerHeight * 0.8;
}

Works like a charm - tested: firefox, chrome

Compare this, without using nonlocal:

x = 0
def outer():
    x = 1
    def inner():
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 1
# global: 0

To this, using nonlocal, where inner()'s x is now also outer()'s x:

x = 0
def outer():
    x = 1
    def inner():
        nonlocal x
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 2
# global: 0

If we were to use global, it would bind x to the properly "global" value:

x = 0
def outer():
    x = 1
    def inner():
        global x
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 1
# global: 2

I get this problem everytime i save a file that gets dynamically compiled (ascx, aspx etc). I wait about 8-10 seconds then it goes away. It's hellishly annoying.

I thought it was perhaps an IIS Express problem so I tried in the inbuilt dev server and am still receiving it after saving a file. I'm running an MVC app, i'm also using T4MVC, maybe that is a factor...

git push origin --delete origin/test 

should work as well

I created a class wrapped in an ES6 module that solves exactly this.

It's 103 lines, no dependencies, and fairly nicely structured and documented, meant to be easy to modify/reuse.

Handles all 8 possible orientations, and is Promise-based.

Here you go, hope this still helps someone: https://gist.github.com/vdavid/3f9b66b60f52204317a4cc0e77097913

I tried the above scenario and got the same error 5 (access denied). I did a deep dive and found that the file .bak should have access to the SQL service account. If you are not sure, type services.msc in Start -> Run then check for SQL Service logon account.

Then go to the file, right-click and select Security tab in Properties, then edit to add the new user.

Finally then give full permission to it in order to give full access.

Then from SSMS try to restore the backup.

if your field name is Roles and table name is table1 you can use following to search

DECLARE @Role varchar(50);
SELECT * FROM table1
WHERE Roles.exist ('/root/role = sql:variable("@Role")') = 1

" error: command 'gcc' failed with exit status 1 ". the installation failed because of missing python-devel and some dependencies.

the best way to correct gcc problem:

You need to reinstall gcc , gcc-c++ and dependencies.

For python 2.7

$ sudo yum -y install gcc gcc-c++ kernel-devel
$ sudo yum -y install python-devel libxslt-devel libffi-devel openssl-devel
$ pip install "your python packet"

For python 3.4

$ sudo apt-get install python3-dev
$ pip install "your python packet"

Hope this will help.

Easiest for me to remember is two operations:

chmod -R 644 dirName
chmod -R +X dirName

The +X only affects directories.

You can use the rename.vars in the gdata package.

library(gdata)
df <- rename.vars(df, from = "oldname", to = "newname")

This is particularly useful where you have more than one variable name to change or you want to append or pre-pend some text to the variable names, then you can do something like:

df <- rename.vars(df, from = c("old1", "old2", "old3", 
         to = c("new1", "new2", "new3"))

For an example of appending text to a subset of variables names see: https://stackoverflow.com/a/28870000/180892

You can use a deep watcher for that:

watch: {
  item: {
     handler(val){
       // do stuff
     },
     deep: true
  }
}

This will now detect any changes to the objects in the item array and additions to the array itself (when used with Vue.set). Here's a JSFiddle: http://jsfiddle.net/je2rw3rs/

EDIT

If you don't want to watch for every change on the top level object, and just want a less awkward syntax for watching nested objects directly, you can simply watch a computed instead:

var vm = new Vue({
  el: '#app',
  computed: {
    foo() {
      return this.item.foo;
    }
  },
  watch: {
    foo() {
      console.log('Foo Changed!');
    }
  },
  data: {
    item: {
      foo: 'foo'
    }
  }
})

Here's the JSFiddle: http://jsfiddle.net/oa07r5fw/

I use this function to calculate cpu usage. Hope it can help you.

private float readUsage() {
    try {
        RandomAccessFile reader = new RandomAccessFile("/proc/stat", "r");
        String load = reader.readLine();

        String[] toks = load.split(" +");  // Split on one or more spaces

        long idle1 = Long.parseLong(toks[4]);
        long cpu1 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
              + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        try {
            Thread.sleep(360);
        } catch (Exception e) {}

        reader.seek(0);
        load = reader.readLine();
        reader.close();

        toks = load.split(" +");

        long idle2 = Long.parseLong(toks[4]);
        long cpu2 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
            + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        return (float)(cpu2 - cpu1) / ((cpu2 + idle2) - (cpu1 + idle1));

    } catch (IOException ex) {
        ex.printStackTrace();
    }

    return 0;
}

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

Got this from JavaRanch

You can also do it with recursion:

def reverse(text):
    if len(text) <= 1:
        return text

    return reverse(text[1:]) + text[0]

And a simple example for the string hello:

   reverse(hello)
 = reverse(ello) + h           # The recursive step
 = reverse(llo) + e + h
 = reverse(lo) + l + e + h
 = reverse(o) + l + l + e + h  # Base case
 = o + l + l + e + h
 = olleh

IF you have excel 2007, you can use

=NORMSINV(RAND())*SD+MEAN

Because there was a big change in 2010 about excel's function

1. LISTAGG delivers the best performance if sorting is a must(00:00:05.85)

   SELECT pid, LISTAGG(Desc, ' ') WITHIN GROUP (ORDER BY seq) AS description FROM B GROUP BY pid;

2. COLLECT delivers the best performance if sorting is not needed(00:00:02.90):

   SELECT pid, TO_STRING(CAST(COLLECT(Desc) AS varchar2_ntt)) AS Vals FROM B GROUP BY pid;

3. COLLECT with ordering is bit slower(00:00:07.08):

   SELECT pid, TO_STRING(CAST(COLLECT(Desc ORDER BY Desc) AS varchar2_ntt)) AS Vals FROM B GROUP BY pid;

All other techniques were slower.

So, I had this code:

<div class="dropdown-select-wrapper" *ngIf="contentData">
    <button mat-stroked-button [disableRipple]="true" class="mat-button" (click)="openSelect()" [ngClass]="{'only-icon': !contentData?.buttonText?.length}">
      <i *ngIf="contentData.iconClassInfo" class="dropdown-icon {{contentData.iconClassInfo.name}}"></i>
      <span class="button-text" *ngIf="contentData.buttonText">{{contentData.buttonText}}</span>
    </button>
    <mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();">
      <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
        {{option[contentData.optionsStructure.keyName]}}
      </mat-option>
    </mat-select>
  </div>

Here I was using standalone formControl, and I was getting the error we are talking about, which made no sense for me, since I wasn't working with formgroups or formarrays... it only disappeared when I added the *ngIf to the select it self, so is not being used before it actually exists. That's what solved the issue in my case.

<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();" *ngIf="theFormControl">
          <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
            {{option[contentData.optionsStructure.keyName]}}
          </mat-option>
        </mat-select>

Unfortunately I did not have time to test it extensively but here is a memory tip that I have not seen before. For me the required memory was reduced with more than 50%. When you read stuff into R with for example read.csv they require a certain amount of memory. After this you can save them with save("Destinationfile",list=ls()) The next time you open R you can use load("Destinationfile") Now the memory usage might have decreased. It would be nice if anyone could confirm whether this produces similar results with a different dataset.

I prefer to use

<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>

that works well

Use mysqli_fetch_row(). Try this,

$query = "SELECT ssfullname, ssemail FROM userss WHERE user_id = ".$user_id;
$result = mysqli_query($conn, $query);
$row   = mysqli_fetch_row($result);

$ssfullname = $row['ssfullname'];
$ssemail    = $row['ssemail'];

Non bare repository allows you to (into your working tree) capture changes by creating new commits.

Bare repositories are only changed by transporting changes from other repositories.

Even though I'm way late to the party here, I'm going to chime in with some useful tricks from my hardware days. All of these assume 2's compliment representation for signed numbers.

int negate = ~i+1;
int positiveMagnitude = (i ^ (i>>31)) - (i>>31);
int negativeMagnitude = (i>>31) - (i ^ (i>>31));

The predeclared characters are:

& < > " '

See "What are the special characters in XML?" for more information.

    //import java.util.ArrayList;
    //import org.bson.Document;

    Document root = Document.parse("{\n"
            + "  \"name\": \"Json\",\n"
            + "  \"detail\": {\n"
            + "    \"first_name\": \"Json\",\n"
            + "    \"last_name\": \"Scott\",\n"
            + "    \"age\": \"23\"\n"
            + "  },\n"
            + "  \"status\": \"success\"\n"
            + "}");

    System.out.println(((String) root.get("name")));
    System.out.println(((String) ((Document) root.get("detail")).get("first_name")));
    System.out.println(((String) ((Document) root.get("detail")).get("last_name")));
    System.out.println(((String) ((Document) root.get("detail")).get("age")));
    System.out.println(((String) root.get("status")));

Using JQuery, you can do this..

$("#submitbutton").click(
   function() {
      alert("Sending...");
      window.location.replace("path to url");
   }
);

Try adding a semi colon to the end of your structure:

 struct sotrudnik {
    string name;
    string speciality;
    string razread;
    int zarplata;
} //Semi colon here

A connection timeout is the maximum amount of time that the program is willing to wait to setup a connection to another process. You aren't getting or posting any application data at this point, just establishing the connection, itself.

A socket timeout is the timeout when waiting for individual packets. It's a common misconception that a socket timeout is the timeout to receive the full response. So if you have a socket timeout of 1 second, and a response comprised of 3 IP packets, where each response packet takes 0.9 seconds to arrive, for a total response time of 2.7 seconds, then there will be no timeout.

You can use the overloaded constructor of DateTime:

DateTime utcDateTime = new DateTime(dateTime.Year, dateTime.Month, dateTime.Day, dateTime.Hour, dateTime.Minute, dateTime.Second, DateTimeKind.Utc);

// app.js or break it up into seperate files
// whatever structure is your flavor    
angular.module('myApp', [])    

.constant('CONFIG', {
    'APP_NAME' : 'My Awesome App',
    'APP_VERSION' : '0.0.0',
    'GOOGLE_ANALYTICS_ID' : '',
    'BASE_URL' : '',
    'SYSTEM_LANGUAGE' : ''
})

.controller('GlobalVarController', ['$scope', 'CONFIG', function($scope, CONFIG) {

    // If you wish to show the CONFIG vars in the console:
    console.log(CONFIG);

    // And your CONFIG vars in .constant will be passed to the HTML doc with this:
    $scope.config = CONFIG;
}]);

In your HTML:

<span ng-controller="GlobalVarController">{{config.APP_NAME}} | v{{config.APP_VERSION}}</span>

Try this :-

  boolean success = file.renameTo(new File(Destdir, file.getName()));

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

Instead of numpy or scipy, I would recommend pandas to do this more swiftly:

df['data'].rolling(3).mean()

This takes the moving average (MA) of 3 periods of the column "data". You can also calculate the shifted versions, for example the one that excludes the current cell (shifted one back) can be calculated easily as:

df['data'].shift(periods=1).rolling(3).mean()

You're resetting the margin on all elements in the second css block. Default margin is 40px - this should solve the problem:

.my_container ul {list-style:disc outside none; margin-left:40px;}

If you want to make a certain set of JAR files (or .class files) available to every Java application on the machine, then your best bet is to add those files to /Library/Java/Extensions.

Or, if you want to do it for every Java application, but only when your Mac OS X account runs them, then use ~/Library/Java/Extensions instead.

EDIT: If you want to do this only for a particular application, as Thorbjørn asked, then you will need to tell us more about how the application is packaged.

I'm not sure if the previous approaches have stopped working, but in any case, here's another way of removing the warnings:

PYTHONWARNINGS="ignore:Unverified HTTPS request" ./do-insecure-request.py

Basically, adding an environment variable in the context of the script execution.

From the documentation: https://urllib3.readthedocs.org/en/latest/security.html#disabling-warnings

Use https://www.npmjs.com/package/uri-parse-lib for this

var t = parserURI("http://user:[email protected]:8080/directory/file.ext?query=1&next=4&sed=5#anchor");

 $.ajax({
            type: "POST",
            data: {data:the_id},
            url: "http://localhost/test/index.php/data/count_votes",
            success: function(data){
               //data will contain the vote count echoed by the controller i.e.  
                 "yourVoteCount"
              //then append the result where ever you want like
              $("span#votes_number").html(data); //data will be containing the vote count which you have echoed from the controller

                }
            });

in the controller

$data = $_POST['data'];  //$data will contain the_id
//do some processing
echo "yourVoteCount";

Clarification

i think you are confusing

{data:the_id}

with

success:function(data){

both the data are different for your own clarity sake you can modify it as

success:function(vote_count){
$(span#someId).html(vote_count);

I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.

I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.

1. Go to the "Manage NuGet Packages"
2. Select the Installed Package "Microsoft ASP.NET Web API 2.1"
3. Click Manage and check the projects that I manually added before.

pg_dump -d <databasename> -h <hostname> -p <port> -n <schemaname> -f <location of the dump file>

Please notice that you have sufficient privilege to access that schema. If you want take backup as specific user add user name in that command preceded by -U

Thanks for all the replies. I went through all of them and came up with a function that gives the first an last index of each occurrence of the 'needle' substring . I am posting it here in case it will help someone.

Please note, it is not the same as the original request for only the beginning of each occurrence. It suits my usecase better because you don't need to keep the needle length.

function findRegexIndices(text, needle, caseSensitive){
  var needleLen = needle.length,
    reg = new RegExp(needle, caseSensitive ? 'gi' : 'g'),
    indices = [],
    result;

  while ( (result = reg.exec(text)) ) {
    indices.push([result.index, result.index + needleLen]);
  }
  return indices
}

I've done something like before using the JavaScript serialization class:

using System.Web.Script.Serialization;

And:

JavaScriptSerializer jss = new JavaScriptSerializer();

string output = jss.Serialize(ListOfMyObject);
Response.Write(output);
Response.Flush();
Response.End();

In my case It worked by going to project Properties and under Target Framework i selected .NET Framework 4. This is because i have moved to a new machine that had other higher .NET frameworks already installed and the project selected them by default. See what target framework works for you.

Edit your app at www.facebook.com/developers/ and set the "Site URL" to "http://localhost/myapppath".

When done - change it back.

Your regex does not work because [] defines a character class, but what you want is a lookahead:

(?=) - Positive look ahead assertion foo(?=bar) matches foo when followed by bar
(?!) - Negative look ahead assertion foo(?!bar) matches foo when not followed by bar
(?<=) - Positive look behind assertion (?<=foo)bar matches bar when preceded by foo
(?<!) - Negative look behind assertion (?<!foo)bar matches bar when NOT preceded by foo
(?>) - Once-only subpatterns (?>\d+)bar Performance enhancing when bar not present
(?(x)) - Conditional subpatterns
(?(3)foo|fu)bar - Matches foo if 3rd subpattern has matched, fu if not
(?#) - Comment (?# Pattern does x y or z)

So try: (?!bush)

I have struggled mightily to get the behavior I want. This is the easiest and best way to get TypeScript files to compile on save, to the configuration I want, only THIS file (the saved file). It's a tasks.json and a keybindings.json.

As a direct system(...) replacement you may use Open3.popen3(...)

Further discussion: http://tech.natemurray.com/2007/03/ruby-shell-commands.html

$_FILES["file"]["tmp_name"] contains the actual copy of your file content on the server while
$_FILES["file"]["name"] contains the name of the file which you have uploaded from the client computer.

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

Try to split the characters into multiple chunks like the query below and try:

Insert into table (clob_column) values ( to_clob( 'chunk 1' ) || to_clob( 'chunk 2' ) );

It worked for me.

With the help of this post, I create following function with additional length checks

public string ReplaceStringByIndex(string original, string replaceWith, int replaceIndex)
{
    if (original.Length >= (replaceIndex + replaceWith.Length))
    {
        StringBuilder rev = new StringBuilder(original);
        rev.Remove(replaceIndex, replaceWith.Length);
        rev.Insert(replaceIndex, replaceWith);
        return rev.ToString();
    }
    else
    {
        throw new Exception("Wrong lengths for the operation");
    }
}

Update

C# 7.0 now has binary literals, which is awesome.

[Flags]
enum Days
{
    None = 0,
    Sunday    = 0b0000001,
    Monday    = 0b0000010,   // 2
    Tuesday   = 0b0000100,   // 4
    Wednesday = 0b0001000,   // 8
    Thursday  = 0b0010000,   // 16
    Friday    = 0b0100000,   // etc.
    Saturday  = 0b1000000,
    Weekend = Saturday | Sunday,
    Weekdays = Monday | Tuesday | Wednesday | Thursday | Friday
}

Original Post

Since the topic seems to have turned to declaring bit-based flag values in enums, I thought it would be worth pointing out a handy trick for this sort of thing. The left-shift operator (<<) will allow you to push a bit to a specific binary position. Combine that with the ability to declare enum values in terms of other values in the same class, and you have a very easy-to-read declarative syntax for bit flag enums.

[Flags]
enum Days
{
    None        = 0,
    Sunday      = 1,
    Monday      = 1 << 1,   // 2
    Tuesday     = 1 << 2,   // 4
    Wednesday   = 1 << 3,   // 8
    Thursday    = 1 << 4,   // 16
    Friday      = 1 << 5,   // etc.
    Saturday    = 1 << 6,
    Weekend     = Saturday | Sunday,
    Weekdays    = Monday | Tuesday | Wednesday | Thursday | Friday
}

Local storage: It keeps store the user information data without expiration date this data will not be deleted when user closed the browser windows it will be available for day, week, month and year.

In Local storage can store 5-10mb offline data.

//Set the value in a local storage object
localStorage.setItem('name', myName);

//Get the value from storage object
localStorage.getItem('name');

//Delete the value from local storage object
localStorage.removeItem(name);//Delete specifice obeject from local storege
localStorage.clear();//Delete all from local storege

Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.

In Session storage can store upto 5 mb data

//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";

Session: A session is a global variable stored on the server. Each session is assigned a unique id which is used to retrieve stored values.

Cookies: Cookies are data, stored in small text files as name-value pairs, on your computer. Once a cookie has been set, all page requests that follow return the cookie name and value.

If you want to modify the original array instead of returning a new array, use .push()...

array1.push.apply(array1, array2);
array1.push.apply(array1, array3);

I used .apply to push the individual members of arrays 2 and 3 at once.

or...

array1.push.apply(array1, array2.concat(array3));

To deal with large arrays, you can do this in batches.

for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
    array1.push.apply(array1, to_add.slice(n, n+300));
}

If you do this a lot, create a method or function to handle it.

var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);

Object.defineProperty(Array.prototype, "pushArrayMembers", {
    value: function() {
        for (var i = 0; i < arguments.length; i++) {
            var to_add = arguments[i];
            for (var n = 0; n < to_add.length; n+=300) {
                push_apply(this, slice_call(to_add, n, n+300));
            }
        }
    }
});

and use it like this:

array1.pushArrayMembers(array2, array3);

var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
    value: function() {_x000D_
        for (var i = 0; i < arguments.length; i++) {_x000D_
            var to_add = arguments[i];_x000D_
            for (var n = 0; n < to_add.length; n+=300) {_x000D_
                push_apply(this, slice_call(to_add, n, n+300));_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

I do something like this in my development environment by configuring Apache on port 80 as a proxy for my application server on port 8080, with the following Apache config:

NameVirtualHost *
<VirtualHost *>
   <Proxy http://127.0.0.1:8080/*>
      Allow from all
   </Proxy>
   <LocationMatch "/myapp">
      ProxyPass http://127.0.0.1:8080/myapp
      ProxyPassReverse http://127.0.0.1:8080/myapp
      Header add myheader "myvalue"
      RequestHeader set myheader "myvalue"   
   </LocationMatch>
</VirtualHost>

See LocationMatch and RequestHeader documentation.

This adds the header myheader: myvalue to requests going to the application server.

A slightly different approach will allow you to skip GDB entirely. If all you want is a backtrace, the Linux-specific utility 'catchsegv' will catch SIGSEGV and display a backtrace.

One approach is to force all attributes to be dirty. You can do that in each controller, but it gets very messy. It would be better to have a general solution.

The easiest way I could think of was to use a directive

• it will handle the form submit attribute
• it iterates through all form fields and marks pristine fields dirty
• it checks if the form is valid before calling the submit function

Here is the directive

myModule.directive('submit', function() {
  return {
    restrict: 'A',
    link: function(scope, formElement, attrs) {
      var form;
      form = scope[attrs.name];
      return formElement.bind('submit', function() {
        angular.forEach(form, function(field, name) {
          if (typeof name === 'string' && !name.match('^[\$]')) {
            if (field.$pristine) {
              return field.$setViewValue(field.$value);
            }
          }
        });
        if (form.$valid) {
          return scope.$apply(attrs.submit);
        }
      });
    }
  };
});

And update your form html, for example:

 <form ng-submit='justDoIt()'>

becomes:

 <form name='myForm' novalidate submit='justDoIt()'>

In Rails 3

Adding Rails.env = ActiveSupport::StringInquirer.new('production') into the application.rb and rails s will work same as rails server -e production

module BlacklistAdmin
  class Application < Rails::Application

    config.encoding = "utf-8"
    Rails.env = ActiveSupport::StringInquirer.new('production')

    config.filter_parameters += [:password]
  end
end

One of the first differences that I can recall from top of my head are multiple domains running in the same server, partial resource retrieval, this allows you to retrieve and speed up the download of a resource (it's what almost every download accelerator does).

If you want to develop an application like a website or similar, you don't need to worry too much about the differences but you should know the difference between GET and POST verbs at least.

Now if you want to develop a browser then yes, you will have to know the complete protocol as well as if you are trying to develop a HTTP server.

If you are only interested in knowing the HTTP protocol I would recommend you starting with HTTP/1.1 instead of 1.0.

To supplement what everyone else has said above, your js file is being read on the client side when you have a path to it in your HTML file. At least that was the problem for me. I had it as a script in my tag in my index.html Hope this helps!

you need to add padding-top to "fill" element, plus add box-sizing:border-box - sample here bootply

Laravel use array for Form::select. So I passed array like below:

$datas = Items::lists('name', 'id');
$items = array();

foreach ($datas as $data)
{
    $items[$data->id] = $data->name;
}

return \View::make('your view', compact('items',$items));

In your view:

<div class="form-group">
    {!! Form::label('item', 'Item:') !!}
    {!! Form::select('item_id', $items, null, ['class' => 'form-control']) !!}
</div>

Maybe this would perform a bit better in case greater amount of input data does not contain your wanted piece because except has greater cost.

def return_first_match(text):
    result = re.findall('\d+',text)
    result = result[0] if result else ""
    return result
