To view entries in Drupal's own internal log system (the watchdog database table), go to http://example.com/admin/reports/dblog. These can include Drupal-specific errors as well as general PHP or MySQL errors that have been thrown.

Use the watchdog() function to add an entry to this log from your own custom module.

When Drupal bootstraps it uses the PHP function set_error_handler() to set its own error handler for PHP errors. Therefore, whenever a PHP error occurs within Drupal it will be logged through the watchdog() call at admin/reports/dblog. If you look for PHP fatal errors, for example, in /var/log/apache/error.log and don't see them, this is why. Other errors, e.g. Apache errors, should still be logged in /var/log, or wherever you have it configured to log to.

This was so annoying. Open your project, click on Target, Open Build Phases tab. Check your Copy Bundle Resources for any red items.

Like Giampaolo Rodolà's answer, but even more dirty: I really, really intend to spend a long time (soon) understanding the whole subject of encodings and how they apply to Windoze consoles,

For the moment I just wanted sthg which would mean my program would NOT CRASH, and which I understood ... and also which didn't involve importing too many exotic modules (in particular I'm using Jython, so half the time a Python module turns out not in fact to be available).

def pr(s):
    try:
        print(s)
    except UnicodeEncodeError:
        for c in s:
            try:
                print( c, end='')
            except UnicodeEncodeError:
                print( '?', end='')

NB "pr" is shorter to type than "print" (and quite a bit shorter to type than "safeprint")...!

Using code to parse ps aux for linux and tasklist for windows are your best options, until something more general comes along.

For windows, you can reference: http://www.rgagnon.com/javadetails/java-0593.html

Linux can pipe the results of ps aux through grep too, which would make processing/searching quick and easy. I'm sure you can find something similar for windows too.

$.each($('input[type=number]'),function(){
  alert($(this).val());
});

This will alert the value of input type number fields

Demo is present at http://jsfiddle.net/2dJAN/33/

I got same problem, I tried all above, noting solved my problem. Luckely, I solved the problem this way:

echo $SHELL

Output

/bin/zsh
OR 
/bin/bash

If it showing "bash" in output. You have to add env properties in .bashrc file (.bash_profile i did not tried, you can try) or else
It is showing 'zsh' in output. You have to add env properties in .zshrc file, if not exist already you create one no issue.

In case you need to check against any amount of whitespace, not just single space, you can do this:

To strip string of extra white space (also condences whitespace in the middle to one space):

trimmed=`echo -- $original`

The -- ensures that if $original contains switches understood by echo, they'll still be considered as normal arguments to be echoed. Also it's important to not put "" around $original, or the spaces will not get removed.

After that you can just check if $trimmed is empty.

[ -z "$trimmed" ] && echo "empty!"

Would you want the same form with different parts, showing each part accordingly with a button?

Here an example with three steps, that is, three form parts, but it is expandable to any number of form parts. The HTML characters « and » just print respectively « and » which might be interesting for the previous and next button characters.

shows_form_part(1)_x000D_
_x000D_
/* this function shows form part [n] and hides the remaining form parts */_x000D_
function shows_form_part(n){_x000D_
  var i = 1, p = document.getElementById("form_part"+1);_x000D_
  while (p !== null){_x000D_
    if (i === n){_x000D_
      p.style.display = "";_x000D_
    }_x000D_
    else{_x000D_
      p.style.display = "none";_x000D_
    }_x000D_
    i++;_x000D_
    p = document.getElementById("form_part"+i);_x000D_
  }_x000D_
}_x000D_
_x000D_
/* this is called at the last step using info filled during the previous steps*/_x000D_
function calc_sum() {_x000D_
  var sum =_x000D_
    parseInt(document.getElementById("num1").value) +_x000D_
    parseInt(document.getElementById("num2").value) +_x000D_
    parseInt(document.getElementById("num3").value);_x000D_
_x000D_
  alert("The sum is: " + sum);_x000D_
}

<div id="form_part1">_x000D_

</div>

Try with code:

this.state.items[1] = 'new value';
var cloneObj = Object.assign({}, this.state.items);

this.setState({items: cloneObj });

Because it's all just about memory, in the end all the numerical values are stored in binary.

A 32 bit unsigned integer can contain values from all binary 0s to all binary 1s.

When it comes to 32 bit signed integer, it means one of its bits (most significant) is a flag, which marks the value to be positive or negative.

An easy way is to convert the dates into milliseconds after January 1, 1970 (use Date.getTime()) and then compare these values.

From my experience, the way I do it is create a snapshot of your current image, then once its done you'll see it as an option when launching new instances. Simply launch it as a large instance at that point.

This is my approach if I do not want any downtime(i.e. production server) because this solution only takes a server offline only after the new one is up and running(I also use it to add new machines to my clusters by using this approach to only add new machines). If Downtime is acceptable then see Marcel Castilho's answer.

Html (you'll have to put the onclick attribute on every input you want it to work for on the page)

 <input type="text" value="click the input to select" onclick="this.select();"/>

OR A BETTER OPTION

jQuery (this will work for every text input on the page, no need to change your html):

<script  type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.js"></script>  
<script type="text/javascript">
    $(function(){
        $(document).on('click','input[type=text]',function(){ this.select(); });
    });
</script>

If the performance is an issue, you can use this command in MS_DOS:

dir /OD >d:\dir.txt

This command generate a dir.txt file in **d:** root the have all files sorted by date. And then read the file from your code. Also, you add other filters by * and ?.

Even better, you can encapsule this to clear any type of controls you want in one method, like this:

public static void EstadoControles<T>(object control, bool estado, bool limpiar = false) where T : Control
        {
            foreach (var textEdits in ((T)control).Controls.OfType<TextEdit>()) textEdits.Enabled = estado;
            foreach (var textLookUpEdits in ((T)control).Controls.OfType<LookUpEdit>()) textLookUpEdits.Enabled = estado;

            if (!limpiar) return;
            {
                foreach (var textEdits in ((T)control).Controls.OfType<TextEdit>()) textEdits.Text = string.Empty;
                foreach (var textLookUpEdits in ((T)control).Controls.OfType<LookUpEdit>()) textLookUpEdits.EditValue = @"-1";
            }
        }

If none of the above solutions solved your issue like in my case (still stuck with my RestClient module facing 405 ) try to request your Api with a tool like Postman or Fiddler. I mean the problem may be elsewhere like a bad formatted request.

I discover that my RestClient module was asking a 'Put' with an Id paremeter not well formatted :

http://myserver/api/someresource?id=75fd954d-d984-4a31-82fc-8132e1644f78

instead of

http://myserver/api/someresource/75fd954d-d984-4a31-82fc-8132e1644f78

Incidiously, bad formatted request returns 405 - Method Not Allowed (IIS 7.5)

You most likely mean "yyyy-MM-dd" small latter 'm' would imply minutes section.

You should do two things

• add spring.jackson.serialization.write-dates-as-timestamps:false in your application.properties this will disable converting dates to timestamps and instead use a ISO-8601 compliant format

• You can than customize the format by annotating the getter method of you dateOfBirth property with @JsonFormat(pattern="yyyy-MM-dd")

Shoud be stated on the top of the page.

Something like.

After DAYS of digging, someone on IRC suggested that I try to use the

Windows 7.1 SDK Command Prompt

Shortcut (links to C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd"). I think you MUST have the older 7.1 SDK (even on Windows 8.1) because the newer ones use msbuild.exe instead of vcbuild.exe which is what node-gyp wants even though it's twice as old as node at this point :/

Once in that prompt, I had to run the following to get x86 context because the compiler was throwing as error otherwise about architecture:

setenv.cmd /Release /x86

THEN I was able to successfully run npm commands that were trying to use node-gyp to recompile things.

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

Only one column version

• Fill NAN with last valid value

df[column_name].fillna(method='ffill', inplace=True)

• Fill NAN with next valid value

df[column_name].fillna(method='backfill', inplace=True)

I also put an answer there, but the article @Colonel Panic's update refers to suggests forcing TLS 1.2. In the future, when TLS 1.2 is compromised or just superceded, having your code stuck to TLS 1.2 will be considered a deficiency. Negotiation to TLS1.2 is enabled in .Net 4.6 by default. If you have the option to upgrade your source to .Net 4.6, I would highly recommend that change over forcing TLS 1.2.

If you do force TLS 1.2, strongly consider leaving some type of breadcrumb that will remove that force if you do upgrade to the 4.6 or higher framework.

You can try this

func getTime() -> (hour:Int, min:Int, sec:Int) {
        let currentDateTime = NSDate()
        let calendar = NSCalendar.currentCalendar()
        let components = calendar.components([.Hour,.Minute,.Second], fromDate: currentDateTime)
        let hour = components.hour
        let min = components.minute
        let sec = components.second
        return (hour,min,sec)
    }

Now call that method and receive the date with hour,min and second

    let currentTime = self.getTime()
    print("Hour: \(currentTime.hour) Min: \(currentTime.min) Sec: \(currentTime.sec))")

No issues with the latest kartoza/qgis-desktop

I ran

docker pull kartoza/qgis-desktop

followed by

docker run -it --rm --name "qgis-desktop-2-4" -v ${HOME}:/home/${USER} -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY kartoza/qgis-desktop:latest

I did try multiple times without the conflict error - you do have to exit the app beforehand. Also, please note the parameters do differ slightly.

If you're doing some performance tuning it's often recommended to set both -XX:PermSize and -XX:MaxPermSize to the same value to increase JVM efficiency.

Here is some information:

1. Support for large page heap on x86 and amd64 platforms
2. Java Support for Large Memory Pages
3. Setting the Permanent Generation Size

You can also specify -XX:+CMSClassUnloadingEnabled to enable class unloading option if you are using CMS GC. It may help to decrease the probability of Java.lang.OutOfMemoryError: PermGen space

I recently needed to do the same thing, and was pleased that the colspan worked fine with consecutive pipes ||

Tested on v4.5 (latest on macports) and the v5.4 (latest on homebrew). Not sure why it doesn't work on the live preview site you provide.

A simple test that I started with was:

| Header ||
|--------------|
| 0 | 1 |

using the command:

multimarkdown -t html test.md > test.html

Cast it back to its original type, which will be a DataRowView if you're binding a table, and you can then get the Id and Text from the appropriate columns:

foreach(object itemChecked in checkedListBox1.CheckedItems)
{
     DataRowView castedItem = itemChecked as DataRowView;
     string comapnyName = castedItem["CompanyName"];
     int? id = castedItem["ID"];
}

Here are some other approaches you can take.

1. CTE with union:

;WITH cte AS (SELECT a, b, c FROM table1)
SELECT a AS val FROM cte
UNION SELECT b AS val FROM cte
UNION SELECT c AS val FROM cte;

2. CTE with unpivot:

;WITH cte AS (SELECT a, b, c FROM table1)
SELECT DISTINCT val
FROM cte
UNPIVOT (val FOR col IN (a, b, c)) u;

string uriPath =
    "file:\\C:\\Users\\john\\documents\\visual studio 2010\\Projects\\proj";
string localPath = new Uri(uriPath).LocalPath;

According to the curl man page:

You can specify any amount of URLs on the command line. They will be fetched in a sequential manner in the specified order.

So the simplest and most efficient (curl will send them all down a single TCP connection [those to the same origin]) approach would be put them all on a single invocation of curl e.g.:

curl http://example.com/?update_=1 http://example.com/?update_=2

I had the same problem, but with small difference. I had added NetworkConnectionCallback to check situation when internet connection had changed at runtime, and checking like this before sending all requests:

private fun isConnected(): Boolean {
    val activeNetwork = cManager.activeNetworkInfo
    return activeNetwork != null && activeNetwork.isConnected
}

There can be state like CONNECTING (you can see i? when you turn on wifi, icon starts blinking, after connecting to network, image is static). So, we have two different states: one CONNECT another CONNECTING, and when Retrofit tried to send request internet connection is disabled and it throws UnknownHostException. I forgot to add another type of exception in function which was responsible for sending requests.

try{
//for example, retrofit call
}
catch (e: Exception) {
        is UnknownHostException -> "Unknown host!"
        is ConnectException -> "No internet!"
        else -> "Unknown exception!"
    }

It's just a tricky moment that can by related with this problem.

Hope, I will help somebody)

What worked for me was to change my WHERE clause into a SELECT subquery

FROM:

    DELETE FROM CommentTag WHERE [dbo].CommentTag.NoteId = [dbo].FetchedTagTransferData.IssueId

TO:

    DELETE FROM CommentTag WHERE [dbo].CommentTag.NoteId = (SELECT NoteId FROM FetchedTagTransferData)

I created these extensions last night:
you can pass either positive or negative values;

example:

var someDate = new Date();
var expirationDate = someDate.addDays(10);
var previous = someDate.addDays(-5);


Date.prototype.addDays = function (num) {
    var value = this.valueOf();
    value += 86400000 * num;
    return new Date(value);
}

Date.prototype.addSeconds = function (num) {
    var value = this.valueOf();
    value += 1000 * num;
    return new Date(value);
}

Date.prototype.addMinutes = function (num) {
    var value = this.valueOf();
    value += 60000 * num;
    return new Date(value);
}

Date.prototype.addHours = function (num) {
    var value = this.valueOf();
    value += 3600000 * num;
    return new Date(value);
}

Date.prototype.addMonths = function (num) {
    var value = new Date(this.valueOf());

    var mo = this.getMonth();
    var yr = this.getYear();

    mo = (mo + num) % 12;
    if (0 > mo) {
        yr += (this.getMonth() + num - mo - 12) / 12;
        mo += 12;
    }
    else
        yr += ((this.getMonth() + num - mo) / 12);

    value.setMonth(mo);
    value.setYear(yr);
    return value;
}

This relative path to absolute path converter shell function

• requires no utilities (just cd and pwd)
• works for directories and files
• handles .. and .
• handles spaces in dir or filenames
• requires that file or directory exists
• returns nothing if nothing exists at the given path
• handles absolute paths as input (passes them through essentially)

Code:

function abspath() {
    # generate absolute path from relative path
    # $1     : relative filename
    # return : absolute path
    if [ -d "$1" ]; then
        # dir
        (cd "$1"; pwd)
    elif [ -f "$1" ]; then
        # file
        if [[ $1 = /* ]]; then
            echo "$1"
        elif [[ $1 == */* ]]; then
            echo "$(cd "${1%/*}"; pwd)/${1##*/}"
        else
            echo "$(pwd)/$1"
        fi
    fi
}

Sample:

# assume inside /parent/cur
abspath file.txt        => /parent/cur/file.txt
abspath .               => /parent/cur
abspath ..              => /parent
abspath ../dir/file.txt => /parent/dir/file.txt
abspath ../dir/../dir   => /parent/dir          # anything cd can handle
abspath doesnotexist    =>                      # empty result if file/dir does not exist
abspath /file.txt       => /file.txt            # handle absolute path input

Note: This is based on the answers from nolan6000 and bsingh, but fixes the file case.

I also understand that the original question was about an existing command line utility. But since this seems to be THE question on stackoverflow for that including shell scripts that want to have minimal dependencies, I put this script solution here, so I can find it later :)

The more efficient (less obtrusive) way of doing this is through custom formatting.

1. Highlight the column/array you want to style.
2. Click ctrl + 1 or Format -> Format Cells.
3. In the Number tab, choose Custom.
4. Set the Custom formatting to 000#. (zero zero zero #)

Note that this does not actually change the value of the cell. It only displays the leading zeroes in the worksheet.

Suppose we haven't used the "@" operator then our code would look like this:

$fileHandle = fopen($fileName, $writeAttributes);

And what if the file we are trying to open is not found? It will show an error message.

To suppress the error message we are using the "@" operator like:

$fileHandle = @fopen($fileName, $writeAttributes);

I believe you could create you own branch (using your own credential) from the same trunk as your workmate's branch, merge from your workmate's branch to your working copy and then merge from your branch. All future commit should be marked as coming from you.

Here is an article that explains it all, with their performance difference and usage over JOINS.

SQL Server CROSS APPLY and OUTER APPLY over JOINS

As suggested in this article, there is no performance difference between them for normal join operations (INNER AND CROSS).

The usage difference arrives when you have to do a query like this:

CREATE FUNCTION dbo.fn_GetAllEmployeeOfADepartment(@DeptID AS INT)  
RETURNS TABLE 
AS 
RETURN 
   ( 
   SELECT * FROM Employee E 
   WHERE E.DepartmentID = @DeptID 
   ) 
GO 
SELECT * FROM Department D 
CROSS APPLY dbo.fn_GetAllEmployeeOfADepartment(D.DepartmentID)

That is, when you have to relate with function. This cannot be done using INNER JOIN, which would give you the error "The multi-part identifier "D.DepartmentID" could not be bound." Here the value is passed to the function as each row is read. Sounds cool to me. :)

All of the provided answers are more complicated than necessary. Assuming you are building a jar file, all you need to do is add a <jar.finalName> tag to your <properties> section:

<properties>
    <jar.finalName>${project.name}</jar.finalName>
</properties>

This will generate a jar:

project/target/${project.name}.jar

This is in the documentation - note the User Property:

finalName:
Name of the generated JAR.
Type: java.lang.String
Required: No
User Property: jar.finalName
Default: ${project.build.finalName}

Command Line Usage

You should also be able to use this option on the command line with:

mvn -Djar.finalName=myCustomName ...

You should get myCustomName.jar, although I haven't tested this.

If you're working with .net core, you can use the dotnet CLI, for instance

dotnet add package <package name>

You are missing an include : #include <stdlib.h>, so GCC creates an implicit declaration of atof and atod, leading to garbage values.

And the format specifier for double is %f, not %d (that is for integers).

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

int main()
{
  char *test = "12.11";
  double temp = strtod(test,NULL);
  float ftemp = atof(test);
  printf("price: %f, %f",temp,ftemp);
  return 0;
}
/* Output */
price: 12.110000, 12.110000

This is the shortest code that you can use to update the app config file even if don't have a config section defined:

void UpdateAppConfig(string param)
{
   var doc = new XmlDocument();
   doc.Load("YourExeName.exe.config");
   XmlNodeList endpoints = doc.GetElementsByTagName("endpoint");
   foreach (XmlNode item in endpoints)
   {
       var adressAttribute = item.Attributes["address"];
       if (!ReferenceEquals(null, adressAttribute))
       {
           adressAttribute.Value = string.Format("http://mydomain/{0}", param);
       }
   }
   doc.Save("YourExeName.exe.config");
}

I had to restart the rails application on the production so I looked for an another answer. I have found it below:

http://wiki.ocssolutions.com/Restarting_a_Rails_Application_Using_Passenger

For python3 on Ubuntu

 sudo apt-get install python3-setuptools

Have you tried this?:

    $string = '';
    while($row = mysql_fetch_array($result))
    {
    //this will combine all the results into one string
    $string .= '<img src="'.$row['name'].'" />
                <div>'.$row['name'].'</div>
                <div>'.$row['title'].'</div>
                <div>'.$row['description'].'</div>
                <div>'.$row['link'].'</div><br />';

    //or this will add the individual result in an array
 /*
     $yourHtml[] = $row;
*/
    }

then you echo the $tring to the place you want it to be

<div id="place_here">
   <?php echo $string; ?>
   <?php 
     //or
    /*
      echo '<img src="'.$yourHtml[0]['name'].'" />;//change the index, or you just foreach loop it
    */
    ?>
</div>

The left inset is caused by Toolbar's contentInsetStart which by default is 16dp.

Change this to 72dp to align to the keyline.

Update for support library v24.0.0:

To match the Material Design spec there's an additional attribute contentInsetStartWithNavigation which by default is 16dp. Change this if you also have a navigation icon.

I believe that what you want is

int[] k = new int[3];

if (k != null) {  // Note, != and not == as above
    System.out.println(k.length);
}

You newed it up so it was never going to be null.

To complete other answers, the gem-path gem can find the installation path of a particular gem.

Installation:

gem install gem-path

Usage:

gem path rails
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-4.0.13
gem path rails '< 4'
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-3.2.21

This is really handy as you can use it to grep or edit files:

grep -R 'Internal server error' "$(gem path thin)"
subl "$(gem path thin)"

The route engine uses the same sequence as you add rules into it. Once it gets the first matched rule, it will stop checking other rules and take this to search for controller and action.

So, you should:

1. Put your specific rules ahead of your general rules(like default), which means use RouteTable.Routes.MapHttpRoute to map "WithActionApi" first, then "DefaultApi".

2. Remove the defaults: new { id = System.Web.Http.RouteParameter.Optional } parameter of your "WithActionApi" rule because once id is optional, url like "/api/{part1}/{part2}" will never goes into "DefaultApi".

3. Add an named action to your "DefaultApi" to tell the route engine which action to enter. Otherwise once you have more than one actions in your controller, the engine won't know which one to use and throws "Multiple actions were found that match the request: ...". Then to make it matches your Get method, use an ActionNameAttribute.

So your route should like this:

// Map this rule first
RouteTable.Routes.MapRoute(
     "WithActionApi",
     "api/{controller}/{action}/{id}"
 );

RouteTable.Routes.MapRoute(
    "DefaultApi",
    "api/{controller}/{id}",
    new { action="DefaultAction", id = System.Web.Http.RouteParameter.Optional }
);

And your controller:

[ActionName("DefaultAction")] //Map Action and you can name your method with any text
public string Get(int id)
{
    return "object of id id";
}        

[HttpGet]
public IEnumerable<string> ByCategoryId(int id)
{
    return new string[] { "byCategory1", "byCategory2" };
}

var data={
 userName: $('#userName').val(),
 email: $('#email').val(),
 //add other properties similarly
}

and

$.ajax({
        type: "POST",
        url: "http://rt.ja.com/includes/register.php?submit=1",
        data: data

        success: function(html)
        {   
            //alert(html);
            $('#userError').html(html);
            $("#userError").html(userChar);
            $("#userError").html(userTaken);
        }
    });

You dont have to bother about anything else. jquery will handle the serialization etc. also you can append the submit query string parameter submit=1 into the data json object.

Push SVG element to last, so that its z-index will be in top. In SVG, there s no property called z-index. try below javascript to bring the element to top.

var Target = document.getElementById(event.currentTarget.id);
var svg = document.getElementById("SVGEditor");
svg.insertBefore(Target, svg.lastChild.nextSibling);

Target: Is an element for which we need to bring it to top svg: Is the container of elements

To quote other people:

A head is simply a reference to a commit object. Each head has a name (branch name or tag name, etc). By default, there is a head in every repository called master. A repository can contain any number of heads. At any given time, one head is selected as the “current head.” This head is aliased to HEAD, always in capitals".

Note this difference: a “head” (lowercase) refers to any one of the named heads in the repository; “HEAD” (uppercase) refers exclusively to the currently active head. This distinction is used frequently in Git documentation.

Another good source that quickly covers the inner workings of git (and therefor a better understanding of heads/HEAD) can be found here. References (ref:) or heads or branches can be considered like post-it notes stuck onto commits in the commit history. Usually they point to the tip of series of commits, but they can be moved around with git checkout or git reset etc.

Here Is my code For Zip the folders and its sub folders and its files and make it downloadable in zip Format

function zip()

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

if (file_exists($destination)) {
    unlink ($destination);
}

$zip = new ZipArchive;

if (!$zip->open($archive, ZipArchive::CREATE)) {
    return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{

    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    if ($include_dir) {

        $arr = explode("/",$source);
        $maindir = $arr[count($arr)- 1];

        $source = "";
        for ($i=0; $i < count($arr) - 1; $i++) { 
            $source .= '/' . $arr[$i];

If Any Issue With the Code Let Me know.

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

The original post contains the solution (ignore the responses, they don't add anything useful). The interesting work is done by the mentioned unix command readlink with option -f. Works when the script is called by an absolute as well as by a relative path.

For bash, sh, ksh:

#!/bin/bash 
# Absolute path to this script, e.g. /home/user/bin/foo.sh
SCRIPT=$(readlink -f "$0")
# Absolute path this script is in, thus /home/user/bin
SCRIPTPATH=$(dirname "$SCRIPT")
echo $SCRIPTPATH

For tcsh, csh:

#!/bin/tcsh
# Absolute path to this script, e.g. /home/user/bin/foo.csh
set SCRIPT=`readlink -f "$0"`
# Absolute path this script is in, thus /home/user/bin
set SCRIPTPATH=`dirname "$SCRIPT"`
echo $SCRIPTPATH

You've to create empty constructor because JAX-RS initializes the classes... Your constructor must have no arguments:

@XmlRootElement
public class Student implements Serializable {

    public String first_name;
    public String last_name;

    public String getFirst_name() {
        return first_name;
    }

    public void setFirst_name(String first_name) {
        this.first_name = first_name;
    }

    public String getLast_name() {
        return last_name;
    }

    public void setLast_name(String last_name) {
        this.last_name = last_name;
    }

    public Student()
    {
        first_name = "Fahad";
        last_name = "Mullaji";
    }


 public Student()
    {
    }
}

To enable use bind() method

$("#id").bind("click",eventhandler);

call this handler

 function  eventhandler(){
      alert("Bind click")
    }

To disable click useunbind()

$("#id").unbind("click");

No, there is no way to create an abstract class in Objective-C.

You can mock an abstract class - by making the methods/ selectors call doesNotRecognizeSelector: and therefore raise an exception making the class unusable.

For example:

- (id)someMethod:(SomeObject*)blah
{
     [self doesNotRecognizeSelector:_cmd];
     return nil;
}

You can also do this for init.

After a few hours of playing with the Oracle JDK 1.6, I was able to make it work without any code change. The magic is done by Bouncy Castle to handle SSL and allow JDK 1.6 to run with TLSv1.2 by default. In theory, it could also be applied to older Java versions with eventual adjustments.

1. Download the latest Java 1.6 version from the Java Archive Oracle website
2. Uncompress it on your preferred path and set your JAVA_HOME environment variable
3. Update the JDK with the latest Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 6
4. Download the Bounce Castle files bcprov-jdk15to18-165.jar and bctls-jdk15to18-165.jar and copy them into your ${JAVA_HOME}/jre/lib/ext folder
5. Modify the file ${JAVA_HOME}/jre/lib/security/java.security commenting out the providers section and adding some extra lines

    # Original security providers (just comment it)
    # security.provider.1=sun.security.provider.Sun
    # security.provider.2=sun.security.rsa.SunRsaSign
    # security.provider.3=com.sun.net.ssl.internal.ssl.Provider
    # security.provider.4=com.sun.crypto.provider.SunJCE
    # security.provider.5=sun.security.jgss.SunProvider
    # security.provider.6=com.sun.security.sasl.Provider
    # security.provider.7=org.jcp.xml.dsig.internal.dom.XMLDSigRI
    # security.provider.8=sun.security.smartcardio.SunPCSC

    # Add the Bouncy Castle security providers with higher priority
    security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
    security.provider.2=org.bouncycastle.jsse.provider.BouncyCastleJsseProvider
    
    # Original security providers with different priorities
    security.provider.3=sun.security.provider.Sun
    security.provider.4=sun.security.rsa.SunRsaSign
    security.provider.5=com.sun.net.ssl.internal.ssl.Provider
    security.provider.6=com.sun.crypto.provider.SunJCE 
    security.provider.7=sun.security.jgss.SunProvider
    security.provider.8=com.sun.security.sasl.Provider
    security.provider.9=org.jcp.xml.dsig.internal.dom.XMLDSigRI
    security.provider.10=sun.security.smartcardio.SunPCSC

    # Here we are changing the default SSLSocketFactory implementation
    ssl.SocketFactory.provider=org.bouncycastle.jsse.provider.SSLSocketFactoryImpl

Just to make sure it's working let's make a simple Java program to download files from one URL using https.

import java.io.*;
import java.net.*;


public class DownloadWithHttps {

    public static void main(String[] args) {
        try {
            URL url = new URL(args[0]);
            System.out.println("File to Download: " + url);
            String filename = url.getFile();
            File f = new File(filename);
            System.out.println("Output File: " + f.getName());
            BufferedInputStream in = new BufferedInputStream(url.openStream());
            FileOutputStream fileOutputStream = new FileOutputStream(f.getName());
            int bytesRead;
            byte dataBuffer[] = new byte[1024];

            while ((bytesRead = in.read(dataBuffer, 0, 1024)) != -1) {
                fileOutputStream.write(dataBuffer, 0, bytesRead);
            }
            fileOutputStream.close();

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

    }
}

Now, just compile the DownloadWithHttps.java program and execute it with your Java 1.6

${JAVA_HOME}/bin/javac DownloadWithHttps.java
${JAVA_HOME}/bin/java DownloadWithHttps https://repo1.maven.org/maven2/org/apache/commons/commons-lang3/3.10/commons-lang3-3.10.jar

Important note for Windows users: This solution was tested in a Linux OS, if you are using Windows, please replace the ${JAVA_HOME} by %JAVA_HOME%.

List<Employee> employees = new List<Employee>()
{
    new Employee{Id =1,Name="AAAAA"}
    , new Employee{Id =2,Name="BBBBB"}
    , new Employee{Id =3,Name="AAAAA"}
    , new Employee{Id =4,Name="CCCCC"}
    , new Employee{Id =5,Name="AAAAA"}
};

List<Employee> duplicateEmployees = employees.Except(employees.GroupBy(i => i.Name)
                                             .Select(ss => ss.FirstOrDefault()))
                                            .ToList();

While, i would completely suggest using beautiful-soup in general, if anyone is looking to display the visible parts of a malformed html (e.g. where you have just a segment or line of a web-page) for whatever-reason, the the following will remove content between < and > tags:

import re   ## only use with malformed html - this is not efficient
def display_visible_html_using_re(text):             
    return(re.sub("(\<.*?\>)", "",text))

Using @property and @attribute.setter helps you to not only use the "pythonic" way but also to check the validity of attributes both while creating the object and when altering it.

class Person(object):
    def __init__(self, p_name=None):
        self.name = p_name

    @property
    def name(self):
        return self._name

    @name.setter
    def name(self, new_name):
        if type(new_name) == str: #type checking for name property
            self._name = new_name
        else:
            raise Exception("Invalid value for name")

By this, you actually 'hide' _name attribute from client developers and also perform checks on name property type. Note that by following this approach even during the initiation the setter gets called. So:

p = Person(12)

Will lead to:

Exception: Invalid value for name

But:

>>>p = person('Mike')
>>>print(p.name)
Mike
>>>p.name = 'George'
>>>print(p.name)
George
>>>p.name = 2.3 # Causes an exception

Instead of returning a resultsArray you return a promise for a results array and then then that on the call site - this has the added benefit of the caller knowing the function is performing asynchronous I/O. Coding concurrency in JavaScript is based on that - you might want to read this question to get a broader idea:

function resultsByName(name)
{   
    var Card = Parse.Object.extend("Card");
    var query = new Parse.Query(Card);
    query.equalTo("name", name.toString());

    var resultsArray = [];

    return query.find({});                           

}

// later
resultsByName("Some Name").then(function(results){
    // access results here by chaining to the returned promise
});

You can see more examples of using parse promises with queries in Parse's own blog post about it.

import-module Microsoft.Exchange.Management.PowerShell.E2010aTry with some implementation like:

$exchangeser = "MTLServer01"

or

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

use this function:

    public static string ConvertDataTableToHTML(DataTable dt)
    {
        string html = "<table>";
        //add header row
        html += "<tr>";
        for(int i=0;i<dt.Columns.Count;i++)
            html+="<td>"+dt.Columns[i].ColumnName+"</td>";
        html += "</tr>";
        //add rows
        for (int i = 0; i < dt.Rows.Count; i++)
        {
            html += "<tr>";
            for (int j = 0; j< dt.Columns.Count; j++)
                html += "<td>" + dt.Rows[i][j].ToString() + "</td>";
            html += "</tr>";
        }
        html += "</table>";
        return html;
    }

With Eclipse and Windows:

you have to copy 2 files - xxxPROJECTxxx.properties - log4j.properties here : C:\Eclipse\CONTENER\TOMCAT\apache-tomcat-7\lib

if($('#chk_all').is(":checked"))
 {
    $('#'+id).attr('checked', true);
 }
else
 {
    $('#'+id).attr('checked', false);
 }  

Using backtick or qx helps, thanks everybody for the answers. However, I found that if you use backtick or qx, the output contains trailing newline and I need to remove that. So I used chomp.

chomp($host = `hostname`);
chomp($domain = `domainname`);
$fqdn = $host.".".$domain;

More information here: http://irouble.blogspot.in/2011/04/perl-chomp-backticks.html

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

For example if you want to read ints :

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

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

Good technical & logical question my dear friend. No in robots.txt file you can't go with relative URL of the sitemap; you need to go with the complete URL of the sitemap.

It's better to go with "sitemap: https://www.example.com/sitemap_index.xml"

In the above URL after the colon gives space. I also like to support Deepak.

This helps me a lot.

$(yourSelector).find('select option:eq(0)').prop('selected', true);

I had to set

Container_height = Element1_height = Element2_height

.Container {
    position: relative;
}

.ElementOne, .Container ,.ElementTwo{
    width: 283px;
    height: 71px;
}

.ElementOne {
    position:absolute;
}

.ElementTwo{
    position:absolute;
}

Use can use z-index to set which one to be on top.

My situation was a little different. The solution was to strip the .pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared. After converting from pfx to pem file, the certificate looked like this:

Bag Attributes
localKeyID: ...
issuer=...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
Bag Attributes
more garbage...
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----

After correcting the file, it was just:

-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

The GO command isn't a Transact-SQL statement, but a special command recognized by several MS utilities including SQL Server Management Studio code editor.

The GO command is used to group SQL commands into batches which are sent to the server together. The commands included in the batch, that is, the set of commands since the last GO command or the start of the session, must be logically consistent. For example, you can't define a variable in one batch and then use it in another since the scope of the variable is limited to the batch in which it's defined.

If you are looking for a programmatical modal creation, you might love this:

Even though Bootstrap's modal provides a javascript way for modal creation, you still need to write modal's html markups first.

In addition to the still very relevant answer of jujule, I find it quite important to also be aware of the implications of order_by() on distinct("field_name") queries. This is, however, a Postgres only feature!

If you are using Postgres and if you define a field name that the query should be distinct for, then order_by() needs to begin with the same field name (or field names) in the same sequence (there may be more fields afterward).

Note

When you specify field names, you must provide an order_by() in the QuerySet, and the fields in order_by() must start with the fields in distinct(), in the same order.

For example, SELECT DISTINCT ON (a) gives you the first row for each value in column a. If you don’t specify an order, you’ll get some arbitrary row.

If you want to e-g- extract a list of cities that you know shops in , the example of jujule would have to be adapted to this:

# returns an iterable Queryset of cities.
models.Shop.objects.order_by('city').values_list('city', flat=True).distinct('city')  

Don't make it a int(), but make it a range() will solve this problem.

inp = range(input("Enter a number: "))

The magic method __getitem__ is basically used for accessing list items, dictionary entries, array elements etc. It is very useful for a quick lookup of instance attributes.

Here I am showing this with an example class Person that can be instantiated by 'name', 'age', and 'dob' (date of birth). The __getitem__ method is written in a way that one can access the indexed instance attributes, such as first or last name, day, month or year of the dob, etc.

import copy

# Constants that can be used to index date of birth's Date-Month-Year
D = 0; M = 1; Y = -1

class Person(object):
    def __init__(self, name, age, dob):
        self.name = name
        self.age = age
        self.dob = dob

    def __getitem__(self, indx):
        print ("Calling __getitem__")
        p = copy.copy(self)

        p.name = p.name.split(" ")[indx]
        p.dob = p.dob[indx] # or, p.dob = p.dob.__getitem__(indx)
        return p

Suppose one user input is as follows:

p = Person(name = 'Jonab Gutu', age = 20, dob=(1, 1, 1999))

With the help of __getitem__ method, the user can access the indexed attributes. e.g.,

print p[0].name # print first (or last) name
print p[Y].dob  # print (Date or Month or ) Year of the 'date of birth'

CN refers to class name, so put in your LDAP query CN=Users. Should work.

I wrote the HTML table in JSP. Course is is a type. For example Course cs, cs= object of type Course which had 2 attributes: id, title. courses is an ArrayList of Course objects.

The HTML table displays all the courses titles in each cell. So the table has 1 column only: Course1 Course2 Course3 ...... Taking aside:

 onclick="DoNav('http://localhost:8080/Mydata/ComplexSearch/FoundS.jsp?courseId=<%=cs.getCourseId()%>');"

This means that after user selects a table cell, for example "Course2", the title of the course- "Course2" will travel to the page where the URL is directing the user: http://localhost:8080/Mydata/ComplexSearch/FoundS.jsp . "Course2" will arrive in FoundS.jsp page. The identifier of "Course2" is courseId. To declare the variable courseId, in which CourseX will be kept, you put a "?" after the URL and next to it the identifier. It works.

You can format the jquery date with this line:

moment($(elem).datepicker('getDate')).format("YYYY-MM-DD");

You use attach without detach - every time you do it new call to attach masks objects attached before (they contain the same names). Either use detach or do not use attach at all. Nice discussion and tips are here.

Version 1:

// Update data of question values with $data from formulay
$Q1 = Question::find($id);
$Q1->fill($data);
$Q1->push();

Version 2:

$Q1 = Question::find($id);
$Q1->field = 'YOUR TEXT OR VALUE';
$Q1->save();

In case of answered question you can use them:

$page = Page::find($id);
$page2update = $page->where('image', $path);
$page2update->image = 'IMGVALUE';
$page2update->save();

$date = '2009-10-22';
$sepparator = '-';
$parts = explode($sepparator, $date);
$dayForDate = date("l", mktime(0, 0, 0, $parts[1], $parts[2], $parts[0]));

UPDATE databaseName.tableName
SET columnName = replace(columnName, '?', '''')
WHERE columnName LIKE '%?%'

For me the reason I was getting NPE is that I was using Mockito.any() when mocking primitives. I found that by switching to using the correct variant from mockito gets rid of the errors.

For example, to mock a function that takes a primitive long as parameter, instead of using any(), you should be more specific and replace that with any(Long.class) or Mockito.anyLong().

Hope that helps someone.

This is primarily a long comment supporting and building on the answer by @mattway

Given:

Some of the other proposed solutions on this page advocate hitting the datastore on every request. If you hit the main datastore to validate every authentication request, then I see less reason to use JWT instead of other established token authentication mechanisms. You've essentially made JWT stateful, instead of stateless if you go to the datastore each time.

(If your site receives a high volume of unauthorized requests, then JWT would deny them without hitting the datastore, which is helpful. There are probably other use cases like that.)

Given:

Truly stateless JWT authentication cannot be achieved for a typical, real world web app because stateless JWT does not have a way to provide immediate and secure support for the following important use cases:

User's account is deleted/blocked/suspended.

User's password is changed.

User's roles or permissions are changed.

User is logged out by admin.

Any other application critical data in the JWT token is changed by the site admin.

You cannot wait for token expiration in these cases. The token invalidation must occur immediately. Also, you cannot trust the client not to keep and use a copy of the old token, whether with malicious intent or not.

Therefore: I think the answer from @matt-way, #2 TokenBlackList, would be most efficient way to add the required state to JWT based authentication.

You have a blacklist that holds these tokens until their expiration date is hit. The list of tokens will be quite small compared to the total number of users, since it only has to keep blacklisted tokens until their expiration. I'd implement by putting invalidated tokens in redis, memcached or another in-memory datastore that supports setting an expiration time on a key.

You still have to make a call to your in-memory db for every authentication request that passes initial JWT auth, but you don't have to store keys for your entire set of users in there. (Which may or may not be a big deal for a given site.)

You can get it by using document.getElementById();

var fileVal=document.getElementById("some Id");
alert(fileVal.value);

will give the value of file,but it gives with fakepath as follows

c:\fakepath\filename

Project Description

Cactus is a simple test framework for unit testing server-side java code (Servlets, EJBs, Tag Libs, Filters, ...).

The intent of Cactus is to lower the cost of writing tests for server-side code. It uses JUnit and extends it.

Cactus implements an in-container strategy, meaning that tests are executed inside the container.

var value1=$("id1").val();
var value2=$("id2").val();
data:"{'data1':'"+value1+"','data2':'"+value2+"'}"

Suppose you have this file:

$ cat /tmp/test.txt
Line 1
    Line 2 has leading space
Line 3 followed by blank line

Line 5 (follows a blank line) and has trailing space    
Line 6 has no ending CR

There are four elements that will alter the meaning of the file output read by many Bash solutions:

1. The blank line 4;
2. Leading or trailing spaces on two lines;
3. Maintaining the meaning of individual lines (i.e., each line is a record);
4. The line 6 not terminated with a CR.

If you want the text file line by line including blank lines and terminating lines without CR, you must use a while loop and you must have an alternate test for the final line.

Here are the methods that may change the file (in comparison to what cat returns):

1) Lose the last line and leading and trailing spaces:

$ while read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'

(If you do while IFS= read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt instead, you preserve the leading and trailing spaces but still lose the last line if it is not terminated with CR)

2) Using process substitution with cat will reads the entire file in one gulp and loses the meaning of individual lines:

$ for p in "$(cat /tmp/test.txt)"; do printf "%s\n" "'$p'"; done
'Line 1
    Line 2 has leading space
Line 3 followed by blank line

Line 5 (follows a blank line) and has trailing space    
Line 6 has no ending CR'

(If you remove the " from $(cat /tmp/test.txt) you read the file word by word rather than one gulp. Also probably not what is intended...)

The most robust and simplest way to read a file line-by-line and preserve all spacing is:

$ while IFS= read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
'    Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space    '
'Line 6 has no ending CR'

If you want to strip leading and trading spaces, remove the IFS= part:

$ while read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'
'Line 6 has no ending CR'

(A text file without a terminating \n, while fairly common, is considered broken under POSIX. If you can count on the trailing \n you do not need || [[ -n $line ]] in the while loop.)

More at the BASH FAQ

I had the same problem, I fixed it by removing PATHEXT from user variable. It must only exist in System variable with .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

Also remove the variable from user to system and only include that path on user variable

Use this code --

function myFunction() {
var str = "How are you doing today?";
var res = str.split("/");

}

Try using String.Split Method:

string text = @"First line
second line
third line";

foreach (string line in text.Split('\n'))
{
    // do something
}

I learned something really useful and fundamental from here.

chaining functions is very usefull in this case which works on most jQuery Functions including on function output too.

It works because output of most jQuery functions are the input objects sets so you can use them right away and make it shorter and smarter

function showPhotos() {
    $(this).find("span").slideToggle();
}

$(".photos")
    .on("mouseenter", "li", showPhotos)
    .on("mouseleave", "li", showPhotos);

Simple ASP.NET MVC subscription form with email textbox would be implemented like that:

Model

The data from the form is mapped to this model

public class SubscribeModel
{
    [Required]
    public string Email { get; set; }
}

View

View name should match controller method name.

@model App.Models.SubscribeModel

@using (Html.BeginForm("Subscribe", "Home", FormMethod.Post))
{
    @Html.TextBoxFor(model => model.Email)
    @Html.ValidationMessageFor(model => model.Email)
    <button type="submit">Subscribe</button>
}

Controller

Controller is responsible for request processing and returning proper response view.

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Subscribe(SubscribeModel model)
    {
        if (ModelState.IsValid)
        {
            //TODO: SubscribeUser(model.Email);
        }

        return View("Index", model);
    }
}

Here is my project structure. Please notice, "Home" views folder matches HomeController name.

Consider the case statement as well which is compatible with most sh-based shells:

case $str in
/*)
    echo 1
    ;;
*)
    echo 0

The documentation on counting says that for group_by queries it is better to use func.count():

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

Used Rn222's answer and aknuds1's answer to use an ISearchContext that returns either a single element, or a list. And a minimum number of elements can be specified:

public static class SearchContextExtensions
{
    /// <summary>
    ///     Method that finds an element based on the search parameters within a specified timeout.
    /// </summary>
    /// <param name="context">The context where this is searched. Required for extension methods</param>
    /// <param name="by">The search parameters that are used to identify the element</param>
    /// <param name="timeOutInSeconds">The time that the tool should wait before throwing an exception</param>
    /// <returns> The first element found that matches the condition specified</returns>
    public static IWebElement FindElement(this ISearchContext context, By by, uint timeOutInSeconds)
    {
        if (timeOutInSeconds > 0)
        {
            var wait = new DefaultWait<ISearchContext>(context);
            wait.Timeout = TimeSpan.FromSeconds(timeOutInSeconds);
            return wait.Until<IWebElement>(ctx => ctx.FindElement(by));
        }
        return context.FindElement(by);
    }
    /// <summary>
    ///     Method that finds a list of elements based on the search parameters within a specified timeout.
    /// </summary>

    /// <param name="by">The search parameters that are used to identify the element</param>
    /// <param name="timeoutInSeconds">The time that the tool should wait before throwing an exception</param>
    /// <returns>A list of all the web elements that match the condition specified</returns>
    public static IReadOnlyCollection<IWebElement> FindElements(this ISearchContext context, By by, uint timeoutInSeconds)
    {

        if (timeoutInSeconds > 0)
        {
            var wait = new DefaultWait<ISearchContext>(context);
            wait.Timeout = TimeSpan.FromSeconds(timeoutInSeconds);
            return wait.Until<IReadOnlyCollection<IWebElement>>(ctx => ctx.FindElements(by));
        }
        return context.FindElements(by);
    }
    /// <summary>
    ///     Method that finds a list of elements with the minimum amount specified based on the search parameters within a specified timeout.<br/>

    ///     If this number is not met, an exception will be thrown and no elements will be returned
    ///     even if some did meet the criteria
    /// </param>
    /// <returns>A list of all the web elements that match the condition specified</returns>
    public static IReadOnlyCollection<IWebElement> FindElements(this ISearchContext context, By by, uint timeoutInSeconds, int minNumberOfElements)
    {
        var wait = new DefaultWait<ISearchContext>(context);
        if (timeoutInSeconds > 0)
        {
            wait.Timeout = TimeSpan.FromSeconds(timeoutInSeconds);
        }

        // Wait until the current context found the minimum number of elements. If not found after timeout, an exception is thrown
        wait.Until<bool>(ctx => ctx.FindElements(by).Count >= minNumberOfElements);

        // If the elements were successfuly found, just return the list
        return context.FindElements(by);
    }

}

Example usage:

var driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://localhost");
var main = driver.FindElement(By.Id("main"));
// It can be now used to wait when using elements to search
var btn = main.FindElement(By.Id("button"), 10);
btn.Click();
// This will wait up to 10 seconds until a button is found
var button = driver.FindElement(By.TagName("button"), 10)
// This will wait up to 10 seconds until a button is found, and return all the buttons found
var buttonList = driver.FindElements(By.TagName("button"), 10)
// This will wait for 10 seconds until we find at least 5 buttons
var buttonsMin = driver.FindElements(By.TagName("button"), 10, 5);
driver.Close();

Use get_the_category() function.

$post_categories = wp_get_post_categories( 4 );
$categories = get_the_category($post_categories[0]);
var_dump($categories);

Use setState in your view to change employed property of state. This is example of React render engine.

 someFunctionWhichChangeParamEmployed(isEmployed) {
      this.setState({
          employed: isEmployed
      });
 }

 getInitialState() {
      return {
          employed: true
      }
 },

 render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <span>Diff me!</span>
                <MyInput ref="unemployment-reason" name="unemployment-reason" />
                <MyInput ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

inside onstart command put START_STICKY... This service won't kill unless it is doing too much task and kernel wants to kill it for it...

@Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            Log.i("LocalService", "Received start id " + startId + ": " + intent);
            // We want this service to continue running until it is explicitly
            // stopped, so return sticky.
            return START_STICKY;
        }

Now this was a nice little puzzle - great question!

Here's an alternative to Nicola Bonelli's solution that does not rely on the non-standard typeof operator.

Unfortunately, it does not work on GCC (MinGW) 3.4.5 or Digital Mars 8.42n, but it does work on all versions of MSVC (including VC6) and on Comeau C++.

The longer comment block has the details on how it works (or is supposed to work). As it says, I'm not sure which behavior is standards compliant - I'd welcome commentary on that.

update - 7 Nov 2008:

It looks like while this code is syntactically correct, the behavior that MSVC and Comeau C++ show does not follow the standard (thanks to Leon Timmermans and litb for pointing me in the right direction). The C++03 standard says the following:

14.6.2 Dependent names [temp.dep]

Paragraph 3

In the definition of a class template or a member of a class template, if a base class of the class template depends on a template-parameter, the base class scope is not examined during unqualified name lookup either at the point of definition of the class template or member or during an instantiation of the class template or member.

So, it looks like that when MSVC or Comeau consider the toString() member function of T performing name lookup at the call site in doToString() when the template is instantiated, that is incorrect (even though it's actually the behavior I was looking for in this case).

The behavior of GCC and Digital Mars looks to be correct - in both cases the non-member toString() function is bound to the call.

Rats - I thought I might have found a clever solution, instead I uncovered a couple compiler bugs...

#include <iostream>
#include <string>

struct Hello
{
    std::string toString() {
        return "Hello";
    }
};

struct Generic {};


// the following namespace keeps the toString() method out of
//  most everything - except the other stuff in this
//  compilation unit

namespace {
    std::string toString()
    {
        return "toString not defined";
    }

    template <typename T>
    class optionalToStringImpl : public T
    {
    public:
        std::string doToString() {

            // in theory, the name lookup for this call to 
            //  toString() should find the toString() in 
            //  the base class T if one exists, but if one 
            //  doesn't exist in the base class, it'll 
            //  find the free toString() function in 
            //  the private namespace.
            //
            // This theory works for MSVC (all versions
            //  from VC6 to VC9) and Comeau C++, but
            //  does not work with MinGW 3.4.5 or 
            //  Digital Mars 8.42n
            //
            // I'm honestly not sure what the standard says 
            //  is the correct behavior here - it's sort 
            //  of like ADL (Argument Dependent Lookup - 
            //  also known as Koenig Lookup) but without
            //  arguments (except the implied "this" pointer)

            return toString();
        }
    };
}

template <typename T>
std::string optionalToString(T & obj)
{
    // ugly, hacky cast...
    optionalToStringImpl<T>* temp = reinterpret_cast<optionalToStringImpl<T>*>( &obj);

    return temp->doToString();
}



int
main(int argc, char *argv[])
{
    Hello helloObj;
    Generic genericObj;

    std::cout << optionalToString( helloObj) << std::endl;
    std::cout << optionalToString( genericObj) << std::endl;
    return 0;
}

In my situation, in order to include color.sh from the same directory in init.sh, I had to do something as follows.

. ./color.sh

Not sure why the ./ and not color.sh directly. The content of color.sh is as follows.

RED=`tput setaf 1`
GREEN=`tput setaf 2`
BLUE=`tput setaf 4`
BOLD=`tput bold`
RESET=`tput sgr0`

Making use of File color.sh does not error but, the color do not display. I have tested this in Ubuntu 18.04 and the Bash version is:

GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)

SELECT  *  FROM Table1 
WHERE MAKE+MODEL+[Serial Number]  not in
    (select make+model+[serial number] from Table2 
     WHERE make+model+[serial number] IS NOT NULL)

That worked for me, where make+model+[serial number] was one field name

I was also a bit confused between adjustResize and adjustPan when I was a beginner. The definitions given above are correct.
AdjustResize : Main activity's content is resized to make room for soft input i.e keyboard
AdjustPan : Instead of resizing overall contents of the window, it only pans the content so that the user can always see what is he typing
AdjustNothing : As the name suggests nothing is resized or panned. Keyboard is opened as it is irrespective of whether it is hiding the contents or not.

I have a created a example for better understanding

DazWorrall's answer is spot on. Here's a variation that might be useful if your code is structured differently than the OP's:

num_rows_deleted = db.session.query(Model).delete()

Also, don't forget that the deletion won't take effect until you commit, as in this snippet:

try:
    num_rows_deleted = db.session.query(Model).delete()
    db.session.commit()
except:
    db.session.rollback()

If you could reload this, you might be able to use dtypes argument.

pd.read_csv(..., dtype={'COL_NAME':'str'})

Use the :javascript filter. This will generate a script tag and escape the script contents as CDATA:

!!! 5
html(lang="en")
  head
    title "Test"
    :javascript
      if (10 == 10) {
        alert("working")
      }
  body

You can use res.render() or res.redirect() method to redirect to another page using node.js express

Eg:

var bodyParser = require('body-parser');
var express = require('express');
var navigator = require('web-midi-api');
var app = express();

app.use(express.static(__dirname + '/'));

Here in the login section, If the email and password matches in the database then the site is directed to dashbaord.html otherwise we will show page-error.html using res.redirect() method. Also you can use res.render() to render a page in node.js

Generally you cannot translate from a time zone like Asia/Kolkata to a GMT offset like +05:30 or +07:00. A time zone, as the name says, is a place on earth and comprises the historic, present and known future UTC offsets used by the people in that place (for now we can regard GMT and UTC as synonyms, strictly speaking they are not). For example, Asia/Kolkata has been at offset +05:30 since 1945. During periods between 1941 and 1945 it was at +06:30 and before that time at +05:53:20 (yes, with seconds precision). Many other time zones have summer time (daylight saving time, DST) and change their offset twice a year.

Given a point in time, we can make the translation for that particular point in time, though. I should like to provide the modern way of doing that.

java.time and ThreeTenABP

    ZoneId zone = ZoneId.of("Asia/Kolkata");

    ZoneOffset offsetIn1944 = LocalDateTime.of(1944, Month.JANUARY, 1, 0, 0)
            .atZone(zone)
            .getOffset();
    System.out.println("Offset in 1944: " + offsetIn1944);

    ZoneOffset offsetToday = OffsetDateTime.now(zone)
            .getOffset();
    System.out.println("Offset now: " + offsetToday);

Output when running just now was:

Offset in 1944: +06:30
Offset now: +05:30

For the default time zone set zone to ZoneId.systemDefault().

To format the offset with the text GMT use a formatter with OOOO (four uppercase letter O) in the pattern:

    DateTimeFormatter offsetFormatter = DateTimeFormatter.ofPattern("OOOO");
    System.out.println(offsetFormatter.format(offsetToday));

GMT+05:30

I am recommending and in my code I am using java.time, the modern Java date and time API. The TimeZone, Calendar, Date, SimpleDateFormat and DateFormat classes used in many of the other answers are poorly designed and now long outdated, so my suggestion is to avoid all of them.

Question: Can I use java.time on Android?

Yes, java.time works nicely on older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

Here's a complete (yet simple) example of redirecting after X seconds, while updating a counter div:

<html>_x000D_
<body>_x000D_
    <div id="counter">5</div>_x000D_
    <script>_x000D_
        setInterval(function() {_x000D_
            var div = document.querySelector("#counter");_x000D_
            var count = div.textContent * 1 - 1;_x000D_
            div.textContent = count;_x000D_
            if (count <= 0) {_x000D_
                window.location.replace("https://example.com");_x000D_
            }_x000D_
        }, 1000);_x000D_
    </script>_x000D_
</body>_x000D_
</html>

The initial content of the counter div is the number of seconds to wait.

Seems like both the conditions are met, perhaps key('contact') is the issue

 if(store.telefon) {
    detailItems.push( new DetailItem('contact', store.telefon, 'Anrufen', 'fontawesome|phone') );
}
if(store.email) {
    detailItems.push( new DetailItem('contact', store.email, 'Email', 'fontawesome|envelope') );
}

Take a look on your running processes, it seems like your current Tomcat instance did not stop. It's still running and NetBeans tries to start a second Tomcat-instance. Thats the reason for your exception, you just have to stop the first instance, or deploy you code on the current running one

Summary,

Code solution: Here

Configuration solutions: Here

With the help of Mike Chaliy, I found some solutions on how to do this through code. Because this issue is going to affect pretty much all projects we deploy to a live environment I held out for a purely configuration solution. I eventually found one which details how to do it in .net 3.0 and .net 3.5.

Taken from the site, below is an example of how to alter your applications web config:

<system.serviceModel>
    <serviceHostingEnvironment>
        <baseAddressPrefixFilters>
            <add prefix="net.tcp://payroll.myorg.com:8000"/>
            <add prefix="http://shipping.myorg.com:9000"/>
        </baseAddressPrefixFilters>
    </serviceHostingEnvironment>
</system.serviceModel>

In the above example, net.tcp://payroll.myorg.com:8000 and http://shipping.myorg.com:9000 are the only base addresses, for their respective schemes, which will be allowed to be passed through. The baseAddressPrefixFilter does not support any wildcards .

The baseAddresses supplied by IIS may have addresses bound to other schemes not present in baseAddressPrefixFilter list. These addresses will not be filtered out.

Dns solution (untested): I think that if you created a new dns entry specific to your web application, added a new web site, and gave it a single host header matching the dns entry, you would mitigate this issue altogether, and would not have to write custom code or add prefixes to your web.config file.

Check the complete and naturalWidth properties, in that order.

https://stereochro.me/ideas/detecting-broken-images-js

function IsImageOk(img) {
    // During the onload event, IE correctly identifies any images that
    // weren’t downloaded as not complete. Others should too. Gecko-based
    // browsers act like NS4 in that they report this incorrectly.
    if (!img.complete) {
        return false;
    }

    // However, they do have two very useful properties: naturalWidth and
    // naturalHeight. These give the true size of the image. If it failed
    // to load, either of these should be zero.
    if (img.naturalWidth === 0) {
        return false;
    }

    // No other way of checking: assume it’s ok.
    return true;
}

I have faced the same issue and also not using virtual environment. easy_install is working for me.

easy_install boto3

Try this:

printf '\n%s\n' 'I want this on a new line!'

That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.

quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f  %s\n' "$quantity" "$price" "$description"
      38    142.15  advanced widget

Your syntax is slightly wrong. Say:

*/15 * * * * command
  |
  |--> `*/15` would imply every 15 minutes.

* indicates that the cron expression matches for all values of the field.

/ describes increments of ranges.

Add your variables in $GLOBALS super global array like

$GLOBALS['variable'] = 'localhost'; 

and use it globally

or you can use constant which are accessible throughout the script

define('HOSTNAME', 'localhost');  

If you want to find all records that are not NULL, and either empty or have any number of spaces, this will work:

LIKE '%\ '

Make sure that there's a space after the backslash. More info here: http://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html

You need to use the AND function for the multiple conditions:

=IF(AND(A2>=75, A2<=79),0.255,IF(AND(A2>=80, X2<=84),0.327,IF(A2>=85,0.559,0)))

Did you try <br/>, <br><br/> or simply \n ? <br> should be supported according to this source, though.

Supported HTML tags

I like Milingu Kilu's solution but in the same spirit I prefer

sup { vertical-align:top; line-height:100%; }

This works for setting the value of the INPUT:

strftime('%Y-%m-%dT%H:%M:%S', time())

Try the following syntax:

document.body.innerHTML += "<p>My new content</p>";

SELECT COUNT(*) FROM information_schema.tables

One more useful command:
vmstat -s | grep memory
sample output on my machine is:

  2050060 K total memory
  1092992 K used memory
   743072 K active memory
   177084 K inactive memory
   957068 K free memory
   385388 K buffer memory

another useful command to get memory information is:
free
sample output is:

             total       used       free     shared    buffers     cached
Mem:       2050060    1093324     956736        108     385392     386812
-/+ buffers/cache:     321120    1728940
Swap:      2095100       2732    2092368

One observation here is that, the command free gives information about swap space also.
The following link may be useful for you:

You can do this with PureBasic and MsScriptControl

All you need to do is pasting the MsScriptControl to the Purebasic editor and add something like this below

InitScriptControl()
SCtr_AddCode("MsgBox 1")

Was asked here before: Unix command to find lines common in two files

You could also try with perl (credit goes here)

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/'  file1 file2

quick solution could be:

SELECT your_db_column_name from "your_db_schema_name"."your_db_tabel_name";

Observe if the view has the model required:

View

@model IEnumerable<WFAccess.Models.ViewModels.SiteViewModel>

<div class="row">
    <table class="table table-striped table-hover table-width-custom">
        <thead>
            <tr>
....

Controller

[HttpGet]
public ActionResult ListItems()
{
    SiteStore site = new SiteStore();
    site.GetSites();

    IEnumerable<SiteViewModel> sites =
        site.SitesList.Select(s => new SiteViewModel
        {
            Id = s.Id,
            Type = s.Type
        });

    return PartialView("_ListItems", sites);
}

In my case I Use a partial view but runs in normal views

row.IsNull("column")

More efficient (faster) to use Buffer.BlockCopy over Array.CopyTo,

int[] x = new int [] { 1, 2, 3};
int[] y = new int [] { 4, 5 };

int[] z = new int[x.Length + y.Length];
var byteIndex = x.Length * sizeof(int);
Buffer.BlockCopy(x, 0, z, 0, byteIndex);
Buffer.BlockCopy(y, 0, z, byteIndex, y.Length * sizeof(int));

I wrote a simple test program that "warms up the Jitter", compiled in release mode and ran it without a debugger attached, on my machine.

For 10,000,000 iterations of the example in the question

Concat took 3088ms

CopyTo took 1079ms

BlockCopy took 603ms

If I alter the test arrays to two sequences from 0 to 99 then I get results similar to this,

Concat took 45945ms

CopyTo took 2230ms

BlockCopy took 1689ms

From these results I can assert that the CopyTo and BlockCopy methods are significantly more efficient than Concat and furthermore, if performance is a goal, BlockCopy has value over CopyTo.

To caveat this answer, if performance doesn't matter, or there will be few iterations choose the method you find easiest. Buffer.BlockCopy does offer some utility for type conversion beyond the scope of this question.

I was having trouble getting this to work alongside background colours and accessory views in the cell. Ended up having to:

1) Set the cells background view property with a UIView set with a background colour.

let view = UIView()
view.backgroundColor = UIColor.white
self.backgroundView = view

2) Re-position this view in layoutSubviews to add the idea of spacing

override func layoutSubviews() {
    super.layoutSubviews()
    backgroundView?.frame = backgroundView?.frame.inset(by: UIEdgeInsets(top: 2, left: 0, bottom: 0, right: 0)) ?? CGRect.zero
}

I had this problem, too.

Possible causes in my case: I had deleted a duplicated view twice and a view model. I reverted one of the deletes and then the InitializeComponent error appeared. I took these steps.

1. I checked all of the solutions mentioned on this question. The class name and build action were correct.
2. I Cleaned my Solution and rebuilt. Another error appeared. "Error CS2001: Source file '.cs' could not be found"
3. I found this answer and followed the steps.
4. I reloaded the project and cleaned/rebuilt again.
5. My solution builds without errors and my application works now.

This sometimes happen if you remove Java from your path variables. To set the PATH variable again, add the full path of the jdk\bin directory to the PATH variable. Typically, the full path is:

C:\Program Files\Java\jdk-11\bin

To set the PATH variable on Microsoft Windows:

1. Select Control Panel and then System.
2. Click Advanced and then Environment Variables.
3. Add the location of the bin folder of the JDK installation to the PATH variable in system variables.

If you use Eclipse Collections you can use the collectIf() method.

MutableList<Integer> source =
    Lists.mutable.with(1, null, 2, null, 3, null, 4, null, 5);

MutableList<String> result = source.collectIf(Objects::nonNull, String::valueOf);

Assert.assertEquals(Lists.immutable.with("1", "2", "3", "4", "5"), result);

It evaluates eagerly and should be a bit faster than using a Stream.

Note: I am a committer for Eclipse Collections.

You can achieve this by adding border class of bootstrap

like for border left ,you can use border-left

working code

<div class="row">
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="one"><h5>Rich Media Ad Production</h5><img src="images/richmedia.png"></div>
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="two"><h5>Web Design & Development</h5> <img src="images/web.png" ></div>               
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="three"><h5>Mobile Apps Development</h5> <img src="images/mobile.png"></div>

When you use mysql_fetch_object, you get an object (of class stdClass) with all fields for the row inside of it.

Use mysql_fetch_field instead of mysql_fetch_object, that will give you the first field of the result set (id in your case). The docs are here

If you have two unix timestamps, you can use this function (made a little more verbose for the sake of clarity):

// Calculate number of days between two unix timestamps
// ------------------------------------------------------------
var daysBetween = function(timeStampA, timeStampB) {
    var oneDay = 24 * 60 * 60 * 1000; // hours * minutes * seconds * milliseconds
    var firstDate = new Date(timeStampA * 1000);
    var secondDate = new Date(timeStampB * 1000);
    var diffDays = Math.round(Math.abs((firstDate.getTime() - secondDate.getTime())/(oneDay)));
    return diffDays;
};

Example:

daysBetween(1096580303, 1308713220); // 2455

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);

Give a look also as this SQL Fiddle for test.

this works for me try it.

If you want the position relative to the document then:

$("#myTable").offset().top;

but often you will want the position relative to the closest positioned parent:

To resolve this issue:

1. The jstl jar should be in your classpath. If you are using maven, add a dependency to jstl in your pom.xml using the snippet provided here. If you are not using maven, download the jstl jar from here and deploy it into your WEB-INF/lib.

2. Make sure you have the following taglib directive at the top of your jsp:

    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
   

To verify this:-

<div class="Caption">
  Model saved
</div>

Write this -

//div[contains(@class, 'Caption') and text()='Model saved']

And to verify this:-

<div id="alertLabel" class="gwt-HTML sfnStandardLeftMargin sfnStandardRightMargin sfnStandardTopMargin">
  Save to server successful
</div>

Write this -

//div[@id='alertLabel' and text()='Save to server successful']

The best "Pythonic" way to do this, exploiting the with statement, is listed as Example #6 in PEP 343, which gives the background of the statement.

@contextmanager
def opened_w_error(filename, mode="r"):
    try:
        f = open(filename, mode)
    except IOError, err:
        yield None, err
    else:
        try:
            yield f, None
        finally:
            f.close()

Used as follows:

with opened_w_error("/etc/passwd", "a") as (f, err):
    if err:
        print "IOError:", err
    else:
        f.write("guido::0:0::/:/bin/sh\n")

Did you try to chomp the $str1 and $str2?

I found a similar issue with using (another) $str1 eq 'Y' and it only went away when I first did:

chomp($str1);
if ($str1 eq 'Y') {
....
}

works after that.

Hope that helps.

You can save your @change="onChange()" an use watchers. Vue computes and watches, it´s designed for that. In case you only need the value and not other complex Event atributes.

Something like:

  ...
  watch: {
    leaveType () {
      this.whateverMethod(this.leaveType)
    }
  },
  methods: {
     onChange() {
         console.log('The new value is: ', this.leaveType)
     }
  }

The circumflex inside the square brackets means all characters except the subsequent range. You want a circumflex outside of square brackets.

Simple solution for all your web service requests, assuming you're using jQuery:

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    // you can use originalOptions.type || options.type to restrict specific type of requests
    options.data = jQuery.param($.extend(originalOptions.data||{}, { 
      timeStamp: new Date().getTime()
    }));
});

Read more about the jQuery prefilter call here.

If you aren't using jQuery, check the docs for your library of choice. They may have similar functionality.

For better explain Dave Morrissey's answer I have made these steps for wrap with Console Output class in a laravel facade.

1) Create a Facade in your prefer folder (in my case app\Facades):

class ConsoleOutput extends Facade {

 protected static function getFacadeAccessor() { 
     return 'consoleOutput';
 }

}

2) Register a new Service Provider in app\Providers as follow:

class ConsoleOutputServiceProvider extends ServiceProvider
{

 public function register(){
    App::bind('consoleOutput', function(){
        return new \Symfony\Component\Console\Output\ConsoleOutput();
     });
 }

}

3) Add all this stuffs in config\app.php file, registering the provider and alias.

 'providers' => [
   //other providers
    App\Providers\ConsoleOutputServiceProvider::class
 ],
 'aliases' => [
  //other aliases
   'ConsoleOutput' => App\Facades\ConsoleOutput::class,
 ],

That's it, now in any place of your Laravel application, just call your method in this way:

ConsoleOutput::writeln('hello');

Hope this help you.

Local variables are non existent in the memory after the function termination.
However static variables remain allocated in the memory throughout the life of the program irrespective of whatever function.

Additionally from your question, static variables can be declared locally in class or function scope and globally in namespace or file scope. They are allocated the memory from beginning to end, it's just the initialization which happens sooner or later.

When you do from socket import * python is loading a socket module to the current namespace. Thus you can use module's members as if they are defined within your current python module.

When you do import socket, a module is loaded in a separate namespace. When you are accessing its members, you should prefix them with a module name. For example, if you want to refer to a socket class, you will need to write client_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM).

As for the problem with timeout - all you need to do is to change except socket.Timeouterror: to except timeout:, since timeout class is defined inside socket module and you have imported all its members to your namespace.

You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all from the stringr package, though gsub from base R works just as well.

The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.

x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")

(The base R equivalent is gsub("[[:punct:]]", " ", x).)

An alternative is to swap out all non-alphanumeric characters.

str_replace_all(x, "[^[:alnum:]]", " ")

Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.

First you need to determine the revision ID of the last known commit. You can use HEAD^ or HEAD~{1} if you know you need to reverse exactly one commit.

git reset --hard <revision_id_of_last_known_good_commit>
git push --force

var date = new Date()
console.log(" Date in MS last three digit = "+  date.getMilliseconds())
console.log(" MS = "+ Date.now())

Using this we can get date in milliseconds

Firstly, you shouldn't have multiple elements with the same ID on a page - ID should be unique.

You could just remove the id attribute and and replace it with:

<input type='text' name='task'>

and to get an array of the values of task do

var taskArray = new Array();
$("input[name=task]").each(function() {
   taskArray.push($(this).val());
});

if your node_modules got installed in say /home/UserName/ like in my case, your package-lock.json file will also be there. just delete this file, go back to your app folder and run npm init and then npm install <pkgname> (e.g express) and a new node_modules folder will be created for your.

"The use of the checkbox is to determine what Item in the Listview that I selected"

1. Just add the tag to checkbox using setTag() method in the Adapter class. and other side using getTag() method.

         @Override
      public void onBindViewHolder(MyViewHolder holder, int position) {
   
   ServiceHelper helper=userServices.get(position);
   holder.tvServiceName.setText(helper.getServiceName());
   
   if(!helper.isServiceStatus()){
   
       holder.btnAdd.setVisibility(View.VISIBLE);
       holder.btnAdd.setTag(helper.getServiceName());
       holder.checkBoxServiceStatus.setVisibility(View.INVISIBLE);
   
   }else{
   
       holder.checkBoxServiceStatus.setVisibility(View.VISIBLE);
          //This Line
       holder.checkBoxServiceStatus.setTag(helper.getServiceName());
       holder.btnAdd.setVisibility(View.INVISIBLE);
   
      }
   
   }
   

2. In xml code of the checkbox just put the "android:onClick="your method""attribute.

        <CheckBox
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:onClick="checkboxClicked"  
               android:id="@+id/checkBox_Service_row"
               android:layout_marginRight="5dp"
               android:layout_alignParentTop="true"
               android:layout_alignParentRight="true"
               android:layout_alignParentEnd="true" />
   

3. In your class Implement that method "your method".

        protected void checkboxClicked(View view)
         {
   
           CheckBox checkBox=(CheckBox) view;
             String tagName="";
            if(checkBox.isChecked()){
              tagName=checkBox.getTag().toString();
              deleteServices.add(tagName);
              checkboxArrayList.add(checkBox);
           }else {
                  checkboxArrayList.remove(checkBox);
                  tagName=checkBox.getTag().toString();
                       if(deleteServices.size()>0&&deleteServices.contains(tagName)){
    deleteServices.remove(tagName);
       }
     }
   }
   

import platform
platform.architecture()

From the Python docs:

Queries the given executable (defaults to the Python interpreter binary) for various architecture information.

Returns a tuple (bits, linkage) which contain information about the bit architecture and the linkage format used for the executable. Both values are returned as strings.

You're missing a reference to System.Linq.

Add

using System.Linq

to get access to the ToList() function on the current code file.

To give a little bit of information over why this is necessary, Enumerable.ToList<TSource> is an extension method. Extension methods are defined outside the original class that it targets. In this case, the extension method is defined on System.Linq namespace.

If you are just getting started with a new project then I would suggest that you use PDO instead of the old odbc_exec() approach. Here is a simple example:

<?php
$bits = 8 * PHP_INT_SIZE;
echo "(Info: This script is running as $bits-bit.)\r\n\r\n";

$connStr = 
        'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
        'Dbq=C:\\Users\\Gord\\Desktop\\foo.accdb;';

$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$sql = 
        "SELECT AgentName FROM Agents " .
        "WHERE ID < ? AND AgentName <> ?";
$sth = $dbh->prepare($sql);

// query parameter value(s)
$params = array(
        5,
        'Homer'
        );

$sth->execute($params);

while ($row = $sth->fetch()) {
    echo $row['AgentName'] . "\r\n";
}

NOTE: The above approach is sufficient if you do not need to support Unicode characters above U+00FF. If you do need to support such characters then neither PDO_ODBC nor the old odbc_ functions will work; you'll need to use the solution described in this answer.

Set the second TextInput focus, when the previous TextInput's onSubmitEditing is triggered.

Try this

1. Adding a Ref to second TextInput
   ref={(input) => { this.secondTextInput = input; }}

2. Bind focus function to first TextInput's onSubmitEditing event.
   onSubmitEditing={() => { this.secondTextInput.focus(); }}

3. Remember to set blurOnSubmit to false, to prevent keyboard flickering.
   blurOnSubmit={false}

When all done, it should looks like this.

<TextInput
    placeholder="FirstTextInput"
    returnKeyType="next"
    onSubmitEditing={() => { this.secondTextInput.focus(); }}
    blurOnSubmit={false}
/>

<TextInput
    ref={(input) => { this.secondTextInput = input; }}
    placeholder="secondTextInput"
/>

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.

Let me explain using step-by-step guidance.

First, download the source code from https://github.com/rmtheis/tess-two.

Import all three projects. After importing you will get an error. To solve the error you have to create a res folder in the tess-two project

First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"

After doing this in all three project the error should be gone.

Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.

Now you just need to import it into your workspace, but first you have to download android-ndk from this site:

http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file

Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable

Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture

done it

Now open cmd and go to on D:\Android Workspace\tess-two like below

If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:

Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest

Import test-two in this and run OCRTest and run it; you will get the best example of OCR.

You could do it this way but it leaves it as a varchar

declare @s varchar(50)

set @s = '2011-09-28 18:01:00'

select convert(varchar, cast(@s as datetime), 105) + RIGHT(@s, 9)

or

select convert(varchar(20), @s, 105)

A BLOB is a binary string to hold a variable amount of data. For the most part BLOB's are used to hold the actual image binary instead of the path and file info. Text is for large amounts of string characters. Normally a blog or news article would constitute to a TEXT field

L in this case is used stating the storage requirement. (Length|Size + 3) as long as it is less than 224.

Reference: http://dev.mysql.com/doc/refman/5.0/en/blob.html

Try this

<input type="submit" 
       value="HOME" 
       onclick="goHome()" 
       style="font-size : 20px; width: 100%; height: 100px;" /> 

While it seems the question was answered per the OP's request, none of the answers give a good way to get a datetime.date object instead of a datetime.datetime. So for those searching and finding this thread:

datetime.date has no .strptime method; use the one on datetime.datetime instead and then call .date() on it to receive the datetime.date object.

Like so:

>>> from datetime import datetime
>>> datetime.strptime('2014-12-04', '%Y-%m-%d').date()
datetime.date(2014, 12, 4)

The problem is with Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); this line. The Class qualified name is wrong

It is sqlserver.jdbc not jdbc.sqlserver

The answer has already been here. If you don't want to use any library, you can follow these steps:

1. Sort list with data by name
2. Iterate via list with data, and in place when current's item first letter != first letter of next item, insert "special" kind of object.
3. Inside your Adapter place special view when item is "special".

Explanation:

In onCreateViewHolder method we can check viewType and depending on the value (our "special" kind) inflate a special layout.

For example:

public static final int TITLE = 0;
public static final int ITEM = 1;

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (context == null) {
        context = parent.getContext();
    }
    if (viewType == TITLE) {
        view = LayoutInflater.from(context).inflate(R.layout.recycler_adapter_title, parent,false);
        return new TitleElement(view);
    } else if (viewType == ITEM) {
        view = LayoutInflater.from(context).inflate(R.layout.recycler_adapter_item, parent,false);
        return new ItemElement(view);
    }
    return null;
}

where class ItemElement and class TitleElement can look like ordinary ViewHolder :

public class ItemElement extends RecyclerView.ViewHolder {
//TextView text;

public ItemElement(View view) {
    super(view);
   //text = (TextView) view.findViewById(R.id.text);

}

So the idea of all of that is interesting. But i am interested if it's effectively, cause we need to sort the data list. And i think this will take the speed down. If any thoughts about it, please write me :)

And also the opened question : is how to hold the "special" layout on the top, while the items are recycling. Maybe combine all of that with CoordinatorLayout.

No simple way AFAIK. If the target is to keep statement cache ratio high (i.e to not create a statement per every parameter count), you may do the following:

1. create a statement with a few (e.g. 10) parameters:

   ... WHERE A IN (?,?,?,?,?,?,?,?,?,?) ...

2. Bind all actuall parameters

   setString(1,"foo"); setString(2,"bar");

3. Bind the rest as NULL

   setNull(3,Types.VARCHAR) ... setNull(10,Types.VARCHAR)

NULL never matches anything, so it gets optimized out by the SQL plan builder.

The logic is easy to automate when you pass a List into a DAO function:

while( i < param.size() ) {
  ps.setString(i+1,param.get(i));
  i++;
}

while( i < MAX_PARAMS ) {
  ps.setNull(i+1,Types.VARCHAR);
  i++;
}

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

The fastest way to copy a database is to detach-copy-attach method, but the production users will not have database access while the prod db is detached. You can do something like this if your production DB is for example a Point of Sale system that nobody uses during the night.

If you cannot detach the production db you should use backup and restore.

You will have to create the logins if they are not in the new instance. I do not recommend you to copy the system databases.

You can use the SQL Server Management Studio to create the scripts that create the logins you need. Right click on the login you need to create and select Script Login As / Create.

This will lists the orphaned users:

EXEC sp_change_users_login 'Report'

If you already have a login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user'

If you want to create a new login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

In summary, I've fixed the problem by putting the database file (* .db) in a subfolder.

• The subfolder and the database file within it must be a member of the www-data group.
• In the www-data group, you must have the right to write to the subfolder and the database file.

The problem is that there is no app installed to handle opening the PDF. You should use the Intent Chooser, like so:

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Intent intent = Intent.createChooser(target, "Open File");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}   

pep8 was recently added to PyPi.

• pep8 - Python style guide checker
• pep8 is a tool to check your Python code against some of the style conventions in PEP 8.

It is now super easy to check your code against pep8.

public mySentences:Array<Object> = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Or rather,

export interface type{
    id:number;
    text:string;
}

public mySentences:type[] = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

In python2.x there was a dirty hack that served this purpose (NEVER use it unless absolutely necessary):

None < any integer < any string

Thus the check i < '' holds True for any integer i.

It has been reasonably deprecated in python3. Now such comparisons end up with

TypeError: unorderable types: str() < int()

Edit: Although the return type has changed in new versions of HTML (see Tim Down's updated answer), the code below still works.

As others have said, it's a NodeList. Here's a complete, working example you can try:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <script>
            function findTheOddOnes()
            {
                var theOddOnes = document.getElementsByClassName("odd");
                for(var i=0; i<theOddOnes.length; i++)
                {
                    alert(theOddOnes[i].innerHTML);
                }
            }
        </script>
