since most of the devices use eMMC,the file system android uses is ext4,except for the firmware.refer-http://android-developers.blogspot.com/2010/12/saving-data-safely.html

Here is the filesystem on galaxy s4:

• /system ext4

• /data ext4

• /cache ext4

• /firmware vfat

• /data/media /mnt/shell/emulated sdcardfs

The detailed output is as follows:

/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,seclabel,relatime, data=ordered 0 0

/dev/block/platform/msm_sdcc.1/by-name/userdata /data ext4 rw,seclabel,nosuid,no dev,noatime,discard,journal_checksum,journal_async_commit,noauto_da_alloc,data=o rdered 0 0

You need to add some style for span6, smthg like that:

.row-fluid .span6 {
  display: table-cell;
  vertical-align: bottom;
  float: none;
}

and this is your fiddle: http://jsfiddle.net/sgB3T/

If your array of objects is items, you can do:

var items = [{_x000D_
  id: 1,_x000D_
  name: 'john'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'jane'_x000D_
}, {_x000D_
  id: 2000,_x000D_
  name: 'zack'_x000D_
}];_x000D_
_x000D_
var names = items.map(function(item) {_x000D_
  return item['name'];_x000D_
});_x000D_
_x000D_
console.log(names);_x000D_
console.log(items);

Documentation: map()

window.location.hash = '#tries';

This will scroll to the element in question, essentially "focus"ing it.

I would recommend background-size: cover; if you don't want your background to lose its proportions: JS Fiddle

  background: url(image/path) no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;

GitHub Pages is GitHub’s official solution to this problem.

raw.githubusercontent makes all files use the text/plain MIME type, even if the file is a CSS or JavaScript file. So going to https://raw.githubusercontent.com/‹user›/‹repo›/‹branch›/‹filepath› will not be the correct MIME type but instead a plaintext file, and linking it via <link href="..."/> or <script src="..."></script> won’t work—the CSS won’t apply / the JS won’t run.

GitHub Pages hosts your repo at a special URL, so all you have to do is check-in your files and push. Note that in most cases, GitHub Pages requires you to commit to a special branch, gh-pages.

On your new site, which is usually https://‹user›.github.io/‹repo›, every file committed to the gh-pages branch (the most recent commit) is present at this url. So then you can link to your js file via <script src="https://‹user›.github.io/‹repo›/file.js"></script>, and this will be the correct MIME type.

Do you have build files?

Personally, my recommendation is to run this branch parallel to master. On the gh-pages branch, you can edit your .gitignore file to check in all the dist/build files you need for your site (e.g. if you have any minified/compiled files), while keeping them ignored on your master branch. This is useful because you typically don’t want to track changes in build files in your regular repo. Every time you want to update your hosted files, simply merge master into gh-pages, rebuild, commit, and then push.

(protip: you can merge and rebuild in the same commit with these steps:)

$ git checkout gh-pages
$ git merge --no-ff --no-commit master  # prepare the merge but don’t commit it (as if there were a merge conflict)
$ npm run build                         # (or whatever your build process is)
$ git add .                             # stage the newly built files
$ git merge --continue                  # commit the merge
$ git push origin gh-pages

If nothing happens even if you added all the annotation needed, try to add this dependency to your pom.xml, I just faced the same problem and resolved it by adding this one here:

<dependency>
   <groupId>commons-configuration</groupId>
   <artifactId>commons-configuration</artifactId>
   <version>1.9</version>
</dependency>

UPDATE: Turned my solution into a stand-alone python script.

This solution has saved me more than once. Hopefully others find it useful. This python script will find any jupyter kernel using more than cpu_threshold CPU and prompts the user to send a SIGINT to the kernel (KeyboardInterrupt). It will keep sending SIGINT until the kernel's cpu usage goes below cpu_threshold. If there are multiple misbehaving kernels it will prompt the user to interrupt each of them (ordered by highest CPU usage to lowest). A big thanks goes to gcbeltramini for writing code to find the name of a jupyter kernel using the jupyter api. This script was tested on MACOS with python3 and requires jupyter notebook, requests, json and psutil.

Put the script in your home directory and then usage looks like:

python ~/interrupt_bad_kernels.py
Interrupt kernel chews cpu.ipynb; PID: 57588; CPU: 2.3%? (y/n) y

Script code below:

from os import getpid, kill
from time import sleep
import re
import signal

from notebook.notebookapp import list_running_servers
from requests import get
from requests.compat import urljoin
import ipykernel
import json
import psutil


def get_active_kernels(cpu_threshold):
    """Get a list of active jupyter kernels."""
    active_kernels = []
    pids = psutil.pids()
    my_pid = getpid()

    for pid in pids:
        if pid == my_pid:
            continue
        try:
            p = psutil.Process(pid)
            cmd = p.cmdline()
            for arg in cmd:
                if arg.count('ipykernel'):
                    cpu = p.cpu_percent(interval=0.1)
                    if cpu > cpu_threshold:
                        active_kernels.append((cpu, pid, cmd))
        except psutil.AccessDenied:
            continue
    return active_kernels

        response = get(urljoin(ss['url'].replace('localhost', '127.0.0.1'), 'api/sessions'),
                       params={'token': ss.get('token', '')})
        for nn in json.loads(response.text):
            for kernel in active_kernels:
                for arg in kernel[-1]:
                    if arg.count(nn['kernel']['id']):
                        pid = kernel[1]
                        cpu = kernel[0]
                        interrupt = input(
                            'Interrupt kernel {}; PID: {}; CPU: {}%? (y/n) '.format(nn['notebook']['path'], pid, cpu))
                        if interrupt.lower() == 'y':
                            p = psutil.Process(pid)
                            while p.cpu_percent(interval=0.1) > cpu_threshold:
                                kill(pid, signal.SIGINT)
                                sleep(0.5)

if __name__ == '__main__':

I am unsure if the author originally was just asking whether or not this allows duplicate values or if there was an implied question here asking, "How to allow duplicate NULL values while using UNIQUE?" Or "How to only allow one UNIQUE NULL value?"

The question has already been answered, yes you can have duplicate NULL values while using the UNIQUE index.

Since I stumbled upon this answer while searching for "how to allow one UNIQUE NULL value." For anyone else who may stumble upon this question while doing the same, the rest of my answer is for you...

In MySQL you can not have one UNIQUE NULL value, however you can have one UNIQUE empty value by inserting with the value of an empty string.

Warning: Numeric and types other than string may default to 0 or another default value.

You could use Javascript:

// This is in the PHP file and sends a Javascript alert to the client
$message = "wrong answer";
echo "<script type='text/javascript'>alert('$message');</script>";

How can you get the tree-like view of commits in terminal?

git log --graph --oneline --all

is a good start.

You may get some strange letters. They are ASCII codes for colors and structure. To solve this problem add the following to your .bashrc:

export LESS="-R"

such that you do not need use Tig's ASCII filter by

git log --graph --pretty=oneline --abbrev-commit | tig   // Masi needed this 

The article text-based graph from Git-ready contains other options:

git log --graph --pretty=oneline --abbrev-commit

Regarding the article you mention, I would go with Pod's answer: ad-hoc hand-made output.

Jakub Narebski mentions in the comments tig, a ncurses-based text-mode interface for git. See their releases.
It added a --graph option back in 2007.

I was having this problem on Rails 4.2 (with ruby 2.2.3) and had to edit the font-awesome _paths.scss partial to remove references to $fa-font-path and removing a leading forward slash. The following was broken:

@font-face {
  font-family: 'FontAwesome';
  src: font-url('#{$fa-font-path}/fontawesome-webfont.eot?v=#{$fa-version}');
  src: font-url('#{$fa-font-path}/fontawesome-webfont.eot?#iefix&v=#{$fa-version}') format('embedded-opentype'),
    font-url('#{$fa-font-path}/fontawesome-webfont.woff2?v=#{$fa-version}') format('woff2'),
    font-url('#{$fa-font-path}/fontawesome-webfont.woff?v=#{$fa-version}') format('woff'),
    font-url('#{$fa-font-path}/fontawesome-webfont.ttf?v=#{$fa-version}') format('truetype'),
    font-url('#{$fa-font-path}/fontawesome-webfont.svg?v=#{$fa-version}#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

And the following works:

@font-face {
  font-family: 'FontAwesome';
  src: font-url('fontawesome-webfont.eot?v=#{$fa-version}');
  src: font-url('fontawesome-webfont.eot?#iefix&v=#{$fa-version}') format('embedded-opentype'),
    font-url('fontawesome-webfont.woff2?v=#{$fa-version}') format('woff2'),
    font-url('fontawesome-webfont.woff?v=#{$fa-version}') format('woff'),
    font-url('fontawesome-webfont.ttf?v=#{$fa-version}') format('truetype'),
    font-url('fontawesome-webfont.svg?v=#{$fa-version}#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

An alternative would be to simply remove the forward slash following the interpolated $fa-font-path and then define $fa-font-path as an empty string or subdirectory with trailing forward slash (as needed).

Remember to recompile assets and restart your server as needed. For example, on a passenger setup:

prompt> rake assets:clean; rake assets:clobber
prompt> RAILS_ENV=production RAILS_GROUPS=assets rake assets:precompile
prompt> service passenger restart

Then reload your browser.

Since Java 1.7 you can use Files.createFile:

Path pathToFile = Paths.get("/home/joe/foo/bar/myFile.txt");
Files.createDirectories(pathToFile.getParent());
Files.createFile(pathToFile);

A work-around for people who are experiencing a bug like Nathan:

The on-the-fly compiler seems to have a problem with this Extension Method error... adding static didn't help me either.

I'd like to know what causes the bug?

But the work-around is to write a new Extension class (not nested) even in same file and re-build.

Figured that this thread is getting enough views that it's worth passing on (the limited) solution I found. Most people probably tried adding 'static' before google-ing for a solution! and I didn't see this work-around fix anywhere else.

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

At the extreme ranges, an unsigned int can become larger than an int.
Therefore, the compiler generates a warning. If you are sure that this is not a problem, feel free to cast the types to the same type so the warning disappears (use C++ cast so that they are easy to spot).

Alternatively, make the variables the same type to stop the compiler from complaining.
I mean, is it possible to have a negative padding? If so then keep it as an int. Otherwise you should probably use unsigned int and let the stream catch the situations where the user types in a negative number.

I know this is an old thread, but here's a slightly different approach using attributes on the Enumerates and then a helper class to find the enumerate that matches.

This way you could have multiple mappings on a single enumerate.

public enum Age
{
    [Metadata("Value", "New_Born")]
    [Metadata("Value", "NewBorn")]
    New_Born = 1,
    [Metadata("Value", "Toddler")]
    Toddler = 2,
    [Metadata("Value", "Preschool")]
    Preschool = 4,
    [Metadata("Value", "Kindergarten")]
    Kindergarten = 8
}

With my helper class like this

public static class MetadataHelper
{
    public static string GetFirstValueFromMetaDataAttribute<T>(this T value, string metaDataDescription)
    {
        return GetValueFromMetaDataAttribute(value, metaDataDescription).FirstOrDefault();
    }

    private static IEnumerable<string> GetValueFromMetaDataAttribute<T>(T value, string metaDataDescription)
    {
        var attribs =
            value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof (MetadataAttribute), true);
        return attribs.Any()
            ? (from p in (MetadataAttribute[]) attribs
                where p.Description.ToLower() == metaDataDescription.ToLower()
                select p.MetaData).ToList()
            : new List<string>();
    }

    public static List<T> GetEnumeratesByMetaData<T>(string metadataDescription, string value)
    {
        return
            typeof (T).GetEnumValues().Cast<T>().Where(
                enumerate =>
                    GetValueFromMetaDataAttribute(enumerate, metadataDescription).Any(
                        p => p.ToLower() == value.ToLower())).ToList();
    }

    public static List<T> GetNotEnumeratesByMetaData<T>(string metadataDescription, string value)
    {
        return
            typeof (T).GetEnumValues().Cast<T>().Where(
                enumerate =>
                    GetValueFromMetaDataAttribute(enumerate, metadataDescription).All(
                        p => p.ToLower() != value.ToLower())).ToList();
    }

}

you can then do something like

var enumerates = MetadataHelper.GetEnumeratesByMetaData<Age>("Value", "New_Born");

And for completeness here is the attribute:

 [AttributeUsage(AttributeTargets.Field, Inherited = false, AllowMultiple = true)]
public class MetadataAttribute : Attribute
{
    public MetadataAttribute(string description, string metaData = "")
    {
        Description = description;
        MetaData = metaData;
    }

    public string Description { get; set; }
    public string MetaData { get; set; }
}

Do this: Open your turboc2 folder you have tc.exe file inside, beside this file you find another file as named as ' tcinst.exe ' open it.

You will see the installation menu:

select as-- > Option > Directory > Include directory

Here you have to change the path of the directory to the path where your INCLUDE folder is located. Same way change the path to library directory also over restart your tc.exe.

    gradient.colors = [UIColor.white.cgColor,UIColor.white.withAlphaComponent(0).cgColor] //Or any colors
    self.viewThatHoldsGradient.layer.addSublayer(gradient)

}

Use the background-color property instead of the background property in your CSS. So your code will look like this:
.fb-icon:hover {
background: blue;
}

Since phone numbers must conform to a pattern, you can use regular expressions to match the entered phone number against the pattern you define in regexp.

php has both ereg and preg_match() functions. I'd suggest using preg_match() as there's more documentation for this style of regex.

An example

$phone = '000-0000-0000';

if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
  // $phone is valid
}

The most you can get is:

select#xyz {
   border:0px;
   outline:0px;
}

You cannot style it completely, but you can try something like

select#xyz {
  -webkit-appearance: button;
  -webkit-border-radius: 2px;
  -webkit-box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
  -webkit-padding-end: 20px;
  -webkit-padding-start: 2px;
  -webkit-user-select: none;
  background-image: url(../images/select-arrow.png), 
    -webkit-linear-gradient(#FAFAFA, #F4F4F4 40%, #E5E5E5);
  background-position: center right;
  background-repeat: no-repeat;
  border: 1px solid #AAA;
  color: #555;
  font-size: inherit;
  margin: 0;
  overflow: hidden;
  padding-top: 2px;
  padding-bottom: 2px;
  text-overflow: ellipsis;
  white-space: nowrap;
}

Follow the steps given below:

1. Download Plugin Manager from here.

   • You can find the most updated version in the release section in the Git repository:

2. Extract the contents of zip file under "C:\Program Files\Notepad++"

3. Restart Notepad++

That's it !!

Calling script only can not do that if the event is PAGE LOAD event specially.

you need to call, Response.Write(script);

so as above, string script = "alert('" + cleanMessage + "');"; Response.Write(script);

will work in at least for a page load event for sure.

xcopy "$(TargetDir)*$(TargetExt)" "$(SolutionDir)\Scripts\MigrationScripts\Library\" /F /R /Y /I

/F – Displays full source & target file names

/R – This will overwrite read-only files

/Y – Suppresses prompting to overwrite an existing file(s)

/I – Assumes that destination is directory (but must ends with )

A little trick – in target you must end with character \ to tell xcopy that target is directory and not file!

Generally speaking, you can update your index mapping using the put mapping api (reference here) :

curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
    "advert_type" : {
        "properties" : {

          //your new mapping properties

        }
    }
}
'

It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.

You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.

Finally, you will have to reindex your data for your new mapping to be taken into account.

The best solution would really be to create a new index.

If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.

Basically, you get connections in the Sleep state when :

• a PHP script connects to MySQL
• some queries are executed
• then, the PHP script does some stuff that takes time
  • without disconnecting from the DB
• and, finally, the PHP script ends
  • which means it disconnects from the MySQL server

So, you generally end up with many processes in a Sleep state when you have a lot of PHP processes that stay connected, without actually doing anything on the database-side.

A basic idea, so : make sure you don't have PHP processes that run for too long -- or force them to disconnect as soon as they don't need to access the database anymore.

Another thing, that I often see when there is some load on the server :

• There are more and more requests coming to Apache
  • which means many pages to generate
• Each PHP script, in order to generate a page, connects to the DB and does some queries
• These queries take more and more time, as the load on the DB server increases
• Which means more processes keep stacking up

A solution that can help is to reduce the time your queries take -- optimizing the longest ones.

Dynamic Base Url (codeigniter)

Just overwrite the line in config/config.php with the following:

$config['base_url'] = 'http://'.$_SERVER['HTTP_HOST'].'/';

>>> a=range(1,10)
>>> for i in [2,3,7]: a.remove(i)
...
>>> a
[1, 4, 5, 6, 8, 9]

>>> a=range(1,10)
>>> b=map(a.remove,[2,3,7])
>>> a
[1, 4, 5, 6, 8, 9]

use \\: instead of \:.. the \ has special meaning in java strings.

Worked for me:

$(".filter-mobile").click(function() {
   if ($("#menuProdutos").height() > 0) {
      $("#menuProdutos").animate({
         height: 0
      }, 200);
   } else {
      $("#menuProdutos").animate({
         height: 500
      }, 200);
   }
});

Do you mean why doesn't the language support multithreading or why don't JavaScript engines in browsers support multithreading?

The answer to the first question is that JavaScript in the browser is meant to be run in a sandbox and in a machine/OS-independent way, to add multithreading support would complicate the language and tie the language too closely to the OS.

Use option -t for sendmail.

in your case - echo -e $mail | /usr/sbin/sendmail -t and add yout Recepient list to message itself like To: [email protected] [email protected] right after the line From:.....

-t option means - Read message for recipients. To:, Cc:, and Bcc: lines will be scanned for recipient addresses. The Bcc: line will be deleted before transmission.

Floating div's will help what your trying to achieve.

Example

HTML

<div class="container">
<div class="content1 content">
</div>
<div class="content2 content">
</div>
</div>

CSS

.container{
width:100%;
height:200px;
background-color:grey;
}
.content{
float:left;
height:30px;
}
.content1{
background-color:blue;
width:300px;
}
.content2{
width:200px;
background-color:green;
}

Zoom in the page to see the effects.

Hope it helps.

I am using mysql and below syntax worked well for me,

ALTER TABLE table_name MODIFY col_name VARCHAR(12);

I had the same doubts, but could not make any changes on the table, I decided doing the following having seen my ID did not exceed the maximum number setted in the variable @count:

SET @count = 40000000;
UPDATE `users` SET `users`.`id` = @count:= @count + 1;

SET @count = 0;
UPDATE `users` SET `users`.`id` = @count:= @count + 1;

ALTER TABLE `users` AUTO_INCREMENT = 1;

The solution takes, but it's safe and it was necessary because my table owned foreign keys with data in another table.

i don't know of a simple css(2.1 standard)-only solution for circles, but for squares you can do easily:

.squared {
    border: 2x solid black;
}

then, use the following html code:

<img src="…" alt="an image " class="squared" />

The following should work:

cin.flush();

On some systems it's not available and then you can use:

cin.ignore(INT_MAX);

You can use this:

<p>&copy; <%: DateTime.Now.Year %> - My ASP.NET Application</p>

git branch copyOfMyBranch MyBranch

This avoids the potentially time-consuming and unnecessary act of checking out a branch. Recall that a checkout modifies the "working tree", which could take a long time if it is large or contains large files (images or videos, for example).

Here is my working code :

<!DOCTYPE html>
<html>
<head>
<style>
   ul#proList{list-style-position: inside}
   li.item{list-style:none; padding:5px;}
</style>
</head>
<body>
    <div id="renderList"></div>
</body>
<script>
    (function(){
        var ul = document.createElement('ul');
        ul.setAttribute('id','proList');

        productList = ['Electronics Watch','House wear Items','Kids wear','Women Fashion'];

        document.getElementById('renderList').appendChild(ul);
        productList.forEach(renderProductList);

        function renderProductList(element, index, arr) {
            var li = document.createElement('li');
            li.setAttribute('class','item');

            ul.appendChild(li);

            li.innerHTML=li.innerHTML + element;
        }
    })();
</script>
</html>

I suggest using Vladimir Keleshev's pep257 Python program to check your docstrings against PEP-257 and the Numpy Docstring Standard for describing parameters, returns, etc.

pep257 will report divergence you make from the standard and is called like pylint and pep8.

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

maybe your script tab has some problem.

if you set type, must type="application/javascript".

<!DOCTYPE html>
<html>
    <head>
        <title>
            Hello
        </title>
    </head>
    <body>
        <div onclick="showMsg('Hello')">
            Click me show message
        </div>
        <script type="application/javascript">
            function showMsg(item) {
            alert(item);
        }
        </script>
    </body>
</html>

Closes should be done in reverse order of the opens.

Your code should work as you have it see this fiddle.

You'll have to make sure your v.Dt is a proper Date object for it to work though.

{{dt | date:'yyyy-MM-dd HH:mm:ss Z'}}

or if dateFormat is defined in scope as dateFormat = 'yyyy-MM-dd HH:mm:ss Z':

{{dt | date:dateFormat }}

The suggestions for boost::program_options and GNU getopt are good ones.

However, for simple command line options I tend to use std::find

For example, to read the name of a file after a -f command line argument. You can also just detect if a single-word option has been passed in like -h for help.

#include <algorithm>

char* getCmdOption(char ** begin, char ** end, const std::string & option)
{
    char ** itr = std::find(begin, end, option);
    if (itr != end && ++itr != end)
    {
        return *itr;
    }
    return 0;
}

bool cmdOptionExists(char** begin, char** end, const std::string& option)
{
    return std::find(begin, end, option) != end;
}

int main(int argc, char * argv[])
{
    if(cmdOptionExists(argv, argv+argc, "-h"))
    {
        // Do stuff
    }

    char * filename = getCmdOption(argv, argv + argc, "-f");

    if (filename)
    {
        // Do interesting things
        // ...
    }

    return 0;
}

On thing to look out for with this approach you must use std::strings as the value for std::find otherwise the equality check is performed on the pointer values.

I hope it is okay to edit this response instead adding a new one, as this is based on the original answer. I re-wrote the functions slightly and encapsulated them in a class, so here is the code. I thought it might be practical to use it that way as well:

class InputParser{
    public:
        InputParser (int &argc, char **argv){
            for (int i=1; i < argc; ++i)
                this->tokens.push_back(std::string(argv[i]));
        }
        /// @author iain
        const std::string& getCmdOption(const std::string &option) const{
            std::vector<std::string>::const_iterator itr;
            itr =  std::find(this->tokens.begin(), this->tokens.end(), option);
            if (itr != this->tokens.end() && ++itr != this->tokens.end()){
                return *itr;
            }
            static const std::string empty_string("");
            return empty_string;
        }
        /// @author iain
        bool cmdOptionExists(const std::string &option) const{
            return std::find(this->tokens.begin(), this->tokens.end(), option)
                   != this->tokens.end();
        }
    private:
        std::vector <std::string> tokens;
};

int main(int argc, char **argv){
    InputParser input(argc, argv);
    if(input.cmdOptionExists("-h")){
        // Do stuff
    }
    const std::string &filename = input.getCmdOption("-f");
    if (!filename.empty()){
        // Do interesting things ...
    }
    return 0;
}

It is not possible to send POST parameters in the url in a starightforward manner. POST request in itself means sending information in the body.

I found a fairly simple way to do this. Use Postman by Google, which allows you to specify the content-type(a header field) as application/json and then provide name-value pairs as parameters.

You can find clear directions at [2020-09-04: broken link - see comment] http://docs.brightcove.com/en/video-cloud/player-management/guides/postman.html

Just use your url in the place of theirs.

Hope it helps

.h files will nothing to do with compiling ... you only care about cpp files... so type g++ filename1.cpp filename2.cpp main.cpp -o myprogram

means you are compiling each cpp files and then linked them together into myprgram.

then run your program ./myprogram

You could use console.log() if you have a debugged code in what programming software editor you have and you will see the output mostly likely the best editor for me (Google Chrome). Just press F12 and press the Console tab. You will see the result. Happy coding. :)

Tried and tested. I know that this works:

Replace(EmailText, vbNewLine, "<br>")

i.e. vbNewLine is also the equivalent of \n

(This method works for ifs, multiple nested loops and other constructs that you can't break from easily.)

Wrap the code in its own function. Instead of break, use return.

Example:

def some_function():
    if condition_a:
        # do something and return early
        ...
        return
    ...
    if condition_b:
        # do something else and return early
        ...
        return
    ...
    return

if outer_condition:
    ...
    some_function()
    ...

According to the documentation the related method to android:backgroundTint is setBackgroundTintList(ColorStateList list)

Update

Follow this link to know how create a Color State List Resource.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:color="#your_color_here" />
</selector>

then load it using

setBackgroundTintList(contextInstance.getResources().getColorStateList(R.color.your_xml_name));

where contextInstance is an instance of a Context

using AppCompart

btnTag.setSupportButtonTintList(ContextCompat.getColorStateList(Activity.this, R.color.colorPrimary));

Usually, one should put a transaction at the service layer.

But as stated before, the atomicity of an operation is what tells us where an annotation is necessary. Thus, if you use frameworks like Hibernate, where a single "save/update/delete/...modification" operation on an object has the potential to modify several rows in several tables (because of the cascade through the object graph), of course there should also be transaction management on this specific DAO method.

I find this quite tricky, but there is some information on it here at the MatPlotLib FAQ. It is rather cumbersome, and requires finding out about what space individual elements (ticklabels) take up...

Update: The page states that the tight_layout() function is the easiest way to go, which attempts to automatically correct spacing.

Otherwise, it shows ways to acquire the sizes of various elements (eg. labels) so you can then correct the spacings/positions of your axes elements. Here is an example from the above FAQ page, which determines the width of a very wide y-axis label, and adjusts the axis width accordingly:

import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))

def on_draw(event):
   bboxes = []
   for label in labels:
       bbox = label.get_window_extent()
       # the figure transform goes from relative coords->pixels and we
       # want the inverse of that
       bboxi = bbox.inverse_transformed(fig.transFigure)
       bboxes.append(bboxi)

   # this is the bbox that bounds all the bboxes, again in relative
   # figure coords
   bbox = mtransforms.Bbox.union(bboxes)
   if fig.subplotpars.left < bbox.width:
       # we need to move it over
       fig.subplots_adjust(left=1.1*bbox.width) # pad a little
       fig.canvas.draw()
   return False

fig.canvas.mpl_connect('draw_event', on_draw)

plt.show()

I use a similar method to dasblinkenlight's in a function to return a single key value from a Cookie containing a JSON array loaded into a Dictionary as follows:

    /// <summary>
    /// Gets a single key Value from a Json filled cookie with 'cookiename','key' 
    /// </summary>
    public static string GetSpecialCookieKeyVal(string _CookieName, string _key)
    {
        //CALL COOKIE VALUES INTO DICTIONARY
        Dictionary<string, string> dictCookie =
        JsonConvert.DeserializeObject<Dictionary<string, string>>
         (MyCookinator.Get(_CookieName));

        string value;
        if (dictCookie.TryGetValue( _key, out value))
        {
            return value;
        }
        else
        {
            return "0";
        }

    }

Where "MyCookinator.Get()" is another simple Cookie function getting an http cookie overall value.

i was faced this issue when ever the eclipse is not closed (kill eclipse process the from task manager or computer power off), i was tried below steps, it worked for me.

1) Remove the file names start with ".fileTable" from this folder

C:\eclipse\configuration\org.eclipse.osgi.manager

2) Remove the log files like text files start with numeric names from this folder

C:\eclipse\configuration

3) Open Command prompt(cmd) navigate to this folder

C:\eclipse

type below command

eclipse clean start

Expanded from @SeaBrightSystems answer, you could try this:

$s1 = "textasstringwoohoo";
$arr = str_split($s1); //$arr now has character array

My solution to do this:

li span.show::after{
  content: url("/sites/default/files/new5.gif");
  padding-left: 5px;
}

__FILE__ is the filename with extension of the file containing the code being executed.

In foo.rb, __FILE__ would be "foo.rb".

If foo.rb were in the dir /home/josh then File.dirname(__FILE__) would return /home/josh.

If you would like to use INTERSECT option, the SQL is as follows

(SELECT id FROM events WHERE start BETWEEN '2013-06-13' AND '2013-07-22') 
INTERSECT
(SELECT id FROM events WHERE end BETWEEN '2013-06-13' AND '2013-07-22') 

If your List is sorted and has good random access (as ArrayList does), you should look into Collections.binarySearch. Otherwise, you should use List.indexOf, as others have pointed out.

But your algorithm is sound, fwiw (other than the == others have pointed out).

There is not a really pythonic way of repeating something. However, it is a better way:

map(lambda index:do_something(), xrange(10))

If you need to pass the index then:

map(lambda index:do_something(index), xrange(10))

Consider that it returns the results as a collection. So, if you need to collect the results it can help.

NSTimeInterval seconds; // assume this exists
NSDate* ts_utc = [NSDate dateWithTimeIntervalSince1970:seconds];

NSDateFormatter* df_utc = [[[NSDateFormatter alloc] init] autorelease];
[df_utc setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
[df_utc setDateFormat:@"yyyy.MM.dd G 'at' HH:mm:ss zzz"];

NSDateFormatter* df_local = [[[NSDateFormatter alloc] init] autorelease];
[df_local setTimeZone:[NSTimeZone timeZoneWithName:@"EST"]];
[df_local setDateFormat:@"yyyy.MM.dd G 'at' HH:mm:ss zzz"];

NSString* ts_utc_string = [df_utc stringFromDate:ts_utc];
NSString* ts_local_string = [df_local stringFromDate:ts_utc];

// you can also use NSDateFormatter dateFromString to go the opposite way

If performance is a priority, you may want to consider using strftime

https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man3/strftime.3.html

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

The date_diff() function returns the difference between two DateTime objects.

If the first date is before the second date a positive number of days will be returned; otherwise a negative number of days:

<?php
$date1=date_create("2013-03-15");
$date2=date_create("2013-12-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
?>

output will be "+272 days" ;

changing $date1 = "2014-03-15"

 <?php
    $date1=date_create("2014-03-15");
    $date2=date_create("2013-12-12");
    $diff=date_diff($date1,$date2);
    echo $diff->format("%R%a days");
    ?>

Output will be "-93 days"

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

My Apache had something like this in httpd.conf. Just change the ErrorLog and CustomLog settings

<VirtualHost myvhost:80>
    ServerAdmin [email protected]
    DocumentRoot /opt/web
    ServerName myvhost
    ErrorLog logs/myvhost-error_log
    CustomLog logs/myvhost-access_log common
</VirtualHost>

If you are using Visual Studio 2010 or plus then check the target framework that is it .Net Framework 4.0 or .Net Framework 4.0 Client Profile. then change is to .Net Framework 4.0.

You need to add reference this .dll file (System.Drawing.dll) to perform drawing operations.

If it is OK then follow these steps to add reference to System.Drawing.dll

1. In Solution Explorer, right-click on the project node and click Add Reference.
2. In the Add Reference dialog box, select the tab indicating the type of component you want to reference.
3. Select the System.Drawing.dll to reference, then click OK.

If you want to get the visible tbody elements, you could do this:

$('tbody:visible').highlight(myArray[i]);

It looks similar to the answer that Agent_9191 gave, but this one removes the space from the selector, which makes it selects the visible tbody elements instead of the visible descendants.

EDIT:

If you specifically wanted to use a test on the display CSS property of the tbody elements, you could do this:

$('tbody').filter(function() {
     return $(this).css('display') != 'none';
}).highlight(myArray[i]);

If you need to be checking external pages, you won't be able to get away with a pure javascript solution, since any requests to external URLs are blocked. You can get away with it by using JSONP, but that won't work unless the page you're requesting only serves up JSON.

You need to have a proxy on your own server to get the external links for you. This is actually rather simple with any server-side language.

<?php
$contents = file_get_contents($_GET['url']); // please do some sanitation here...
                                             // i'm just showing an example.
echo $contents;
?>

If you needed to check server response codes (eg: 404, 301, etc), then using a library such as cURL in your server-side script could retrieve that information and then pass it onto your javascript app.

Thinking about it now, there probably could be JSONP-enabled proxies out there for you to use, should the "setting up my own proxy" option not be viable.

Here is answer for your question.

db.getCollection('users').aggregate([
    {$match : {admin : 1}},
    {$lookup: {from: "posts",localField: "_id",foreignField: "owner_id",as: "posts"}},
    {$project : {
            posts : { $filter : {input : "$posts"  , as : "post", cond : { $eq : ['$$post.via' , 'facebook'] } } },
            admin : 1

        }}

])

Or either you can go with mongodb group option.

db.getCollection('users').aggregate([
    {$match : {admin : 1}},
    {$lookup: {from: "posts",localField: "_id",foreignField: "owner_id",as: "posts"}},
    {$unwind : "$posts"},
    {$match : {"posts.via":"facebook"}},
    { $group : {
            _id : "$_id",
            posts : {$push : "$posts"}
    }}
])

One thing to keep in mind with positioning is that each view has an index relative to its parent view. So if you have a linear layout with three subviews, the subviews will each have an index: 0, 1, 2 in the above case.

This allows you to add a view to the last position (or the end) in a parent view by doing something like this:

int childCount = parent.getChildCount();
parentView.addView(newView, childCount);

Alternatively you could replace a view using something like the following:

int childIndex = parentView.indexOfChild(childView);
childView.setVisibility(View.GONE);

parentView.addView(newView, childIndex);

If you want to plot a single line connecting all the points in the list

plt.plot(li[:])

plt.show()

This will plot a line connecting all the pairs in the list as points on a Cartesian plane from the starting of the list to the end. I hope that this is what you wanted.

Curly braces are always needed for accessing array elements and carrying out brace expansion.

It's good to be not over-cautious and use {} for shell variable expansion even when there is no scope for ambiguity.

For example:

dir=log
prog=foo
path=/var/${dir}/${prog}      # excessive use of {}, not needed since / can't be a part of a shell variable name
logfile=${path}/${prog}.log   # same as above, . can't be a part of a shell variable name
path_copy=${path}             # {} is totally unnecessary
archive=${logfile}_arch       # {} is needed since _ can be a part of shell variable name

So, it is better to write the three lines as:

path=/var/$dir/$prog
logfile=$path/$prog.log
path_copy=$path

which is definitely more readable.

Since a variable name can't start with a digit, shell doesn't need {} around numbered variables (like $1, $2 etc.) unless such expansion is followed by a digit. That's too subtle and it does make to explicitly use {} in such contexts:

set app      # set $1 to app
fruit=$1le   # sets fruit to apple, but confusing
fruit=${1}le # sets fruit to apple, makes the intention clear

I had a similar problem getting scrollTop to work after reload of div content. The content scrolled to top each time the procedure below was run. I found that a little delay before setting the new scrolltop solved the issue.

This is cut from wdCalendar where I modified this procedure:

 function BuildDaysAndWeekView(startday, l, events, config)
   ....
        var scrollpos = $("#dvtec").scrollTop();
        gridcontainer.html(html.join(""));
        setTimeout(function() {
            $("#dvtec").scrollTop(scrollpos);
        }, 25);
   ....

Without the delay, it simply did not work.

UTF-8 is a method for encoding Unicode characters using 8-bit sequences.

Unicode is a standard for representing a great variety of characters from many languages.

Actually there is a simpler way to do this, just:

if ($("#input").is(':empty')) {
console.log('empty');
} else {
console.log('not empty');
}

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression

=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)

Same way for tolerance

=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

You can use an index in a range and then access the array via its index:

<ul>
  <li v-for="index in 10" :key="index">
    {{ shoppingItems[index].name }} - {{ shoppingItems[index].price }}
  </li>
</ul>

In the project I'm working on, audit log also started from the very minimalistic design, like the one you described:

event ID
event date/time
event type
user ID
description

The idea was the same: to keep things simple.

However, it quickly became obvious that this minimalistic design was not sufficient. The typical audit was boiling down to questions like this:

Who the heck created/updated/deleted a record 
with ID=X in the table Foo and when?

So, in order to be able to answer such questions quickly (using SQL), we ended up having two additional columns in the audit table

object type (or table name)
object ID

That's when design of our audit log really stabilized (for a few years now).

Of course, the last "improvement" would work only for tables that had surrogate keys. But guess what? All our tables that are worth auditing do have such a key!

    jQuery.ajax({
        url: document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(url),
        dataType: 'json',
        success: function(data) {
            callback(data.responseData.feed);
        }
    });
})('http://news.hitb.org/rss.xml', function(feed){ // Change to desired URL
    var entries = feed.entries, feedList = '';

    }
    jQuery('.feed > ul').append(feedList);

Here is an example to call your webservice using jQuery.get:

$.get("http://domain.com/webservice.asmx", { name: "John", time: "2pm" },
  function(data){
    alert("Data Loaded: " + data);
  });

In the example above, we call "webservice.asmx", passing two parameters: name and time. Then, getting the service output in the call back function.

Simply copy your Anaconda bin directory and paste it at the bottom of ~/.zshrc.

For me the path is /home/theorangeguy/miniconda3/bin, so I ran:

echo ". /home/theorangeguy/miniconda3/bin" >> ~/.zshrc

This edited the ~/.zshrc. Now do:

source ~/.zshrc

It worked like a charm.

If you’re using a multi-byte character encoding and do not just want to remove the first four bytes like substr does, use the multi-byte counterpart mb_substr. This does of course will also work with single-byte strings.

The solution you want is the one proposed here:

https://stackoverflow.com/a/542802/50776

Basically, you do this:

cast(floor(cast(@dateVariable as float)) as datetime)

There is a function definition in the link which will allow you to consolidate the functionality and call it anywhere (instead of having to remember it) if you wish.

It can be done.

From the designer: Select your DataGridView Open the Properties Navigate to ColumnHeaderDefaultCellStype Hit the button to edit the style.

You can also do it programmatically:

dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Purple;

Hope that helps!

Looks like you missed a few closing tags and you nshould have "http://" on the front of an external URL. Also, you should move your styles to external style sheets instead of using inline styles.

.box{
  float:right;
}
.box a img{
  vertical-align: middle;
  border: 0px;
}

        <img src="<?php echo url::file_loc('img'); ?>media/img/twitter.png" alt="Image Decription">

As noted in other comments, it may be easier to use straight HTML, depending on your exact setup.

You can mix C++ in with Objectiv-C (Objective C++). Write a C++ method in your Objective C++ class that simply calls [context renderbufferStorage:GL_RENDERBUFFER fromDrawable:(CAEAGLLayer*)self.layer]; and call it from your C++.

I haven't tried it before my self, but give it a shot, and share the results with us.

You can use the iOS simulator to do this. You need to enable "Developer Mode" on Safari (Preferences -> Advanced).

Then open the website you want to debug in the iOS simulator. Go back to safari and under Develop you will see the simulator and the tabs open on safari.

If you want to test an actual device, then just plug it into your computer and it should show there too.

That's how I do it.

A way to use a custom sort function

//func has to return 0 in the case in which they are equal
sort_unique = function(arr,func) {
        func = func || function (a, b) {
            return a*1 - b*1;
        };
        arr = arr.sort(func);
        var ret = [arr[0]];
        for (var i = 1; i < arr.length; i++) {
            if (func(arr[i-1],arr[i]) != 0) 
                ret.push(arr[i]);
            }
        }
        return ret;
    }

Example: desc order for an array of objects

MyArray = sort_unique(MyArray , function(a,b){
            return  b.iterator_internal*1 - a.iterator_internal*1;
        });

Correct Xpath syntax is like:

//tagname[@value='name']

So you should write something like this:

findElement(By.xpath("//input[@test-id='test-username']"));

Hive Partitioning:

Partition divides large amount of data into multiple slices based on value of a table column(s).

Assume that you are storing information of people in entire world spread across 196+ countries spanning around 500 crores of entries. If you want to query people from a particular country (Vatican city), in absence of partitioning, you have to scan all 500 crores of entries even to fetch thousand entries of a country. If you partition the table based on country, you can fine tune querying process by just checking the data for only one country partition. Hive partition creates a separate directory for a column(s) value.

Pros:

1. Distribute execution load horizontally
2. Faster execution of queries in case of partition with low volume of data. e.g. Get the population from "Vatican city" returns very fast instead of searching entire population of world.

Cons:

1. Possibility of too many small partition creations - too many directories.
2. Effective for low volume data for a given partition. But some queries like group by on high volume of data still take long time to execute. e.g. Grouping of population of China will take long time compared to grouping of population in Vatican city. Partition is not solving responsiveness problem in case of data skewing towards a particular partition value.

Hive Bucketing:

Bucketing decomposes data into more manageable or equal parts.

With partitioning, there is a possibility that you can create multiple small partitions based on column values. If you go for bucketing, you are restricting number of buckets to store the data. This number is defined during table creation scripts.

Pros

1. Due to equal volumes of data in each partition, joins at Map side will be quicker.
2. Faster query response like partitioning

Cons

1. You can define number of buckets during table creation but loading of equal volume of data has to be done manually by programmers.

It depends on the output of file which I am not sure is standardized on all systems. Some JPEGs don't report the image size

import subprocess, re
image_size = list(map(int, re.findall('(\d+)x(\d+)', subprocess.getoutput("file" + filename))[-1]))

1. TIMESTAMP is four bytes vs eight bytes for DATETIME.

2. Timestamps are also lighter on the database and indexed faster.

3. The DATETIME type is used when you need values that contain both date and time information. MySQL retrieves and displays DATETIME values in ‘YYYY-MM-DD HH:MM:SS’ format. The supported range is ’1000-01-01 00:00:00' to ’9999-12-31 23:59:59'.

The TIMESTAMP data type has a range of ’1970-01-01 00:00:01' UTC to ’2038-01-09 03:14:07' UTC. It has varying properties, depending on the MySQL version and the SQL mode the server is running in.

4. DATETIME is constant while TIMESTAMP is effected by the time_zone setting.

For a class Book like this:

package books;

public class Book {

    private Integer id;
    private Integer number;
    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public Integer getNumber() {
        return number;
    }

    public void setNumber(Integer number) {
        this.number = number;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "book{" +
                "id=" + id +
                ", number=" + number +
                ", name='" + name + '\'' + '\n' +
                '}';
    }
}

I suggest you take a look at the HTML that the code spits out and see if theres a way to uniquely identify one (or both) of the buttons (possibly the id or name attributes), then use jQuery to select that item and apply a css class to it.

You can try using this code:

protected ServiceConnection mServerConn = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name, IBinder binder) {
        Log.d(LOG_TAG, "onServiceConnected");
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        Log.d(LOG_TAG, "onServiceDisconnected");
    }
}

public void start() {
    // mContext is defined upper in code, I think it is not necessary to explain what is it 
    mContext.bindService(intent, mServerConn, Context.BIND_AUTO_CREATE);
    mContext.startService(intent);
}

public void stop() {
    mContext.stopService(new Intent(mContext, ServiceRemote.class));
    mContext.unbindService(mServerConn);
}

Simple out of the box Stopwatch class:

import java.time.Duration;
import java.time.Instant;

public class StopWatch {

    Instant startTime, endTime;
    Duration duration;
    boolean isRunning = false;

    public void start() {
        if (isRunning) {
            throw new RuntimeException("Stopwatch is already running.");
        }
        this.isRunning = true;
        startTime = Instant.now();
    }

    public Duration stop() {
        this.endTime = Instant.now();
        if (!isRunning) {
            throw new RuntimeException("Stopwatch has not been started yet");
        }
        isRunning = false;
        Duration result = Duration.between(startTime, endTime);
        if (this.duration == null) {
            this.duration = result;

As wordpress api has changed, you can´t use get_posts with param 'post_name'. I´ve modified Maartens function a bit:

function get_post_id_by_slug( $slug, $post_type = "post" ) {
    $query = new WP_Query(
        array(
            'name'   => $slug,
            'post_type'   => $post_type,
            'numberposts' => 1,
            'fields'      => 'ids',
        ) );
    $posts = $query->get_posts();
    return array_shift( $posts );
}

You can use the DataGridView refresh method. But... in a lot of cases you have to refresh the DataGridView from methods running on a different thread than the one where the DataGridView is running. In order to do that you should implement the following method and call it rather than directly typing DataGridView.Refresh():

    private void RefreshGridView()
    {
        if (dataGridView1.InvokeRequired)
        {
            dataGridView1.Invoke((MethodInvoker)delegate ()
            {
                RefreshGridView();
            });
        }
        else
            dataGridView1.Refresh();
    }  

I have a small script interruptableloop.py that runs the code at an interval (default 1sec), it pumps out a message to the screen while it's running, and traps an interrupt signal that you can send with CTL-C:

#!/usr/bin/python3
from interruptableLoop import InterruptableLoop

loop=InterruptableLoop(intervalSecs=1) # redundant argument
while loop.ShouldContinue():
   # some python code that I want 
   # to keep on running
   pass

When you run the script and then interrupt it you see this output, (the periods pump out on every pass of the loop):

[py36]$ ./interruptexample.py

            print ("Exiting at ",dtt.now())
        return self.shouldContinue

You can also fix this issue by modifying the jQuery Ajax function by doing the following (as of 1.7.1) to the top of the Ajax function (function starts at line 7212). This change will activate the built-in anti-cache feature of jQuery for all POST requests.

(The full script is available at http://dl.dropbox.com/u/58016866/jquery-1.7.1.js.)

Insert below line 7221:

if (options.type === "POST") {
    options.cache = false;
}

Then modify the following (starting at line ~7497).

if (!s.hasContent) {
    // If data is available, append data to URL
    if (s.data) {
        s.url += (rquery.test(s.url) ? "&" : "?") + s.data;
        // #9682: remove data so that it's not used in an eventual retry
        delete s.data;
    }

    // Get ifModifiedKey before adding the anti-cache parameter
    ifModifiedKey = s.url;

    // Add anti-cache in URL if needed
    if (s.cache === false) {
        var ts = jQuery.now(),
        // Try replacing _= if it is there
        ret = s.url.replace(rts, "$1_=" + ts);

        // If nothing was replaced, add timestamp to the end.
        s.url = ret + ((ret === s.url) ? (rquery.test(s.url) ? "&" : "?") + "_=" + ts : "");
    }
}

To:

// More options handling for requests with no content
if (!s.hasContent) {
    // If data is available, append data to URL
    if (s.data) {
        s.url += (rquery.test(s.url) ? "&" : "?") + s.data;
        // #9682: remove data so that it's not used in an eventual retry
        delete s.data;
    }

    // Get ifModifiedKey before adding the anti-cache parameter
    ifModifiedKey = s.url;
}

// Add anti-cache in URL if needed
if (s.cache === false) {
    var ts = jQuery.now(),
    // Try replacing _= if it is there
    ret = s.url.replace(rts, "$1_=" + ts);

    // If nothing was replaced, add timestamp to the end.
    s.url = ret + ((ret === s.url) ? (rquery.test(s.url) ? "&" : "?") + "_=" + ts : "");
}

Single quotes are very strong. Once inside, there's nothing you can do to invoke variable substitution, until you leave. Use double quotes instead:

echo $LINE | sed -e "s/12345678/$replace/g"

The best and modern way is typeof (variable) if you care about real number not number from string. For example:

var a = 1;
var b = '1';

typeof a: // Output: "number"
typeof b: // Output: "string

Here is another usage :

#!/bin/bash
array=( "$@" )
arraylength=${#array[@]}
for (( i=0; i<${arraylength}; i++ ));
do
   echo "${array[$i]}"
done

I solved mine by doing:

• mvn clean
• mvn install
• mvn clean install

For some reasons it worked for me . Good luck !!

If your output is delimited by tabs a quick solution would be to use the tabs command to adjust the size of your tabs.

tabs 20
keys | awk '{ print $1"\t\t" $2 }'

The following checklink.cmd program is a good place to start. It relies on the fact that you can do a single-shot ping and that, if successful, the output will contain the line:

Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),

By extracting tokens 5 and 7 and checking they're respectively "Received" and "1,", you can detect the success.

@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
:loop
set state=down
for /f "tokens=5,6,7" %%a in ('ping -n 1 !ipaddr!') do (
    if "x%%b"=="xunreachable." goto :endloop
    if "x%%a"=="xReceived" if "x%%c"=="x1,"  set state=up
)
:endloop
echo.Link is !state!
ping -n 6 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal

Call it with the name (or IP address) you want to test:

checklink 127.0.0.1
checklink localhost
checklink nosuchaddress

Take into account that, if your locale is not English, you must replace Received with the corresponding keyword in your locale, for example recibidos for Spanish. Do a test ping to discover what keyword is used in your locale.

To only notify you when the state changes, you can use:

@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
set oldstate=neither
:loop
set state=down
for /f "tokens=5,7" %%a in ('ping -n 1 !ipaddr!') do (
    if "x%%a"=="xReceived" if "x%%b"=="x1," set state=up
)
if not !state!==!oldstate! (
    echo.Link is !state!
    set oldstate=!state!
)
ping -n 2 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal

However, as Gabe points out in a comment, you can just use ERRORLEVEL so the equivalent of that second script above becomes:

@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
set oldstate=neither
:loop
set state=up
ping -n 1 !ipaddr! >nul: 2>nul:
if not !errorlevel!==0 set state=down
if not !state!==!oldstate! (
    echo.Link is !state!
    set oldstate=!state!
)
ping -n 2 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal

    public static void main(String[] args) {
        long a = 1111;
        Long b = 1113L;
        if(a == b.longValue())
    {
        System.out.println("Equals");
    }else{
        System.out.println("not equals");
    }
  }

or:

    public static void main(String[] args) {
        long a = 1111;
        Long b = 1113L;
        if(a == b)
    {
        System.out.println("Equals");
    }else{
        System.out.println("not equals");
    }
  }

same as a normal modulo 3.14 % 6.28 = 3.14, just like 3.14%4 =3.14 3.14%2 = 1.14 (the remainder...)

Use .parentElement and you can't go wrong as long as you aren't using document fragments.

If you use document fragments, then you need .parentNode:

let div = document.createDocumentFragment().appendChild(document.createElement('div'));
div.parentElement // null
div.parentNode // document fragment

Also:

let div = document.getElementById('t').content.firstChild_x000D_
div.parentElement // null_x000D_
div.parentNode // document fragment

<template id="t"><div></div></template>

Apparently the <html>'s .parentNode links to the Document. This should be considered a decision phail as documents aren't nodes since nodes are defined to be containable by documents and documents can't be contained by documents.

Short Answer

To make a clean install of Python 3.6.5 use:

brew unlink python # ONLY if you have installed (with brew) another version of python 3
brew install --ignore-dependencies https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb

If you prefer to recover a previously installed version, then:

brew info python           # To see what you have previously installed
brew switch python 3.x.x_x # Ex. 3.6.5_1

Long Answer

There are two formulas for installing Python with Homebrew: python@2 and python.
The first is for Python 2 and the second for Python 3.

Note: You can find outdated answers on the web where it is mentioned python3 as the formula name for installing Python version 3. Now it's just python!

By default, with these formulas you can install the latest version of the corresponding major version of Python. So, you cannot directly install a minor version like 3.6.

Solution

With brew, you can install a package using the address of the formula, for example in a git repository.

brew install https://the/address/to/the/formula/FORMULA_NAME.rb

Or specifically for Python 3

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/COMMIT_IDENTIFIER/Formula/python.rb

The address you must specify is the address to the last commit of the formula (python.rb) for the desired version. You can find the commint identifier by looking at the history for homebrew-core/Formula/python.rb

https://github.com/Homebrew/homebrew-core/commits/master/Formula/python.rb

Python > 3.6.5

In the link above you will not find a formula for a version of Python above 3.6.5. After the maintainers of that (official) repository released Python 3.7, they only submit updates to the recipe of Python 3.7.

As explained above, with homebrew you have only Python 2 (python@2) and Python 3 (python), there is no explicit formula for Python 3.6.

Although those minor updates are mostly irrelevant in most cases and for most users, I will search if someone has done an explicit formula for 3.6.

I was facing the same issue in which I need to align selected placeholder value to the right of the select box & also need to align options to right but when I have used direction: rtl; to select & applied some right padding to select then all options also getting shift to the right by padding as I only want to apply padding to selected placeholder.

I have fixed the issue by the following the style:

select:first-child{
  text-indent: 24%;
  direction: rtl;
  padding-right: 7px;
}

select option{
  direction: rtl;
}

You can change text-indent as per your requirement. Hope it will help you.

There is another code that's works for me (jQuery).

$(".datepicker").datepicker({_x000D_

here is the complete example of how you can select and upload multiple files in asp.net using file upload control....

write this code in .aspx file..

<head runat="server">
    <title></title>
</head>
<body>
<form id="form1" runat="server" enctype="multipart/form-data">
<div>
    <input type="file" id="myfile" multiple="multiple" name="myfile" runat="server" size="100" />
    <br />
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    <br />
    <asp:Label ID="Span1" runat="server"></asp:Label>
</div>
</form>
</body>
</html>

after that write this code in .aspx.cs file..

   protected void Button1_Click(object sender,EventArgs e) {
          string filepath = Server.MapPath("\\Upload");
          HttpFileCollection uploadedFiles = Request.Files;
          Span1.Text = string.Empty;

          for(int i = 0;i < uploadedFiles.Count;i++) {
              HttpPostedFile userPostedFile = uploadedFiles[i];

              try {
                  if (userPostedFile.ContentLength > 0) {
                     Span1.Text += "<u>File #" + (i + 1) +  "</u><br>";
                     Span1.Text += "File Content Type: " +  userPostedFile.ContentType      + "<br>";
                     Span1.Text += "File Size: " + userPostedFile.ContentLength           + "kb<br>";
                     Span1.Text += "File Name: " + userPostedFile.FileName + "<br>";

                     userPostedFile.SaveAs(filepath + "\\" +    Path.GetFileName(userPostedFile.FileName));                  
                     Span1.Text += "Location where saved: " +   filepath + "\\" +   Path.GetFileName(userPostedFile.FileName) + "<p>";
                  }
              } catch(Exception Ex) {
                  Span1.Text += "Error: <br>" + Ex.Message;
              }
           }
        }
    }

and here you go...your multiple file upload control is ready..have a happy day.

I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.

Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty().

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

lst = [['a','b','c'], [1,2,3], ['x','y','z']]
outputlist = []
for values in lst:
    outputlist.append(values[0])

print(outputlist) 

Output: ['a', 1, 'x']

A few years late but this might help someone if you are using eval or backtick substitution:

postDataJson="{\"guid\":\"$guid\",\"auth_token\":\"$token\"}"

Using sed to strip quotes from beginning and end of response

$(curl --silent -H "Content-Type: application/json" https://${target_host}/runs/get-work -d ${postDataJson} | sed -e 's/^"//' -e 's/"$//')

For some reason the commands posted before dont work for me, but this one does:

xcrun simctl io booted screenshot screenshot.png

Running Xcode 9.2

I was having this same problem, and tried all the above solutions with no success. I finally solved the problem by deleting the entire query and creating a new one.

The new one had the exact same settings as the one that didn't work (literally the same query definition as I simply copied the old one).

I have no idea why this solved the problem, but it did.

99% of the time I would use XMLHttpRequest or fetch for something like this. However, there's an alternative solution which doesn't require javascript...

You could include a hidden iframe on your page and set the target attribute of your form to point to that iframe.

<style>
  .hide { position:absolute; top:-1px; left:-1px; width:1px; height:1px; }
</style>

<iframe name="hiddenFrame" class="hide"></iframe>

<form action="receiver.pl" method="post" target="hiddenFrame">
  <input name="signed" type="checkbox">
  <input value="Save" type="submit">
</form>

There are very few scenarios where I would choose this route. Generally handling it with javascript is better because, with javascript you can...

• gracefully handle errors (e.g. retry)
• provide UI indicators (e.g. loading, processing, success, failure)
• run logic before the request is sent, or run logic after the response is received.

Maybe this helps:

a = [{ 'main_color': 'red', 'second_color':'blue'},
     { 'main_color': 'yellow', 'second_color':'green'},
     { 'main_color': 'yellow', 'second_color':'blue'}]

def in_dictlist((key, value), my_dictlist):
    for this in my_dictlist:
        if this[key] == value:
            return this
    return {}

print in_dictlist(('main_color','red'), a)
print in_dictlist(('main_color','pink'), a)

you can use cutycapt .

kwhtml is deprecated and show page like old browser.

You can call more than one target goal with maven. mvn clean install calls clean first, then install. You have to clean manually, because clean is not a standard target goal and not executed automatically on every install.

clean removes the target folder - it deletes all class files, the java docs, the jars, reports and so on. If you don't clean, then maven will only "do what has to be done", like it won't compile classes when the corresponding source files haven't changed (in brief).

^{we call it target in ant and goal in maven}

You should try doing it with css3 animation. Check the code bellow:

<!DOCTYPE html>
<html>
<head>
<style> 
div {
    width: 100px;
    height: 100px;
    background: red;
    position: relative;
    -webkit-animation: myfirst 5s infinite; /* Chrome, Safari, Opera */
    -webkit-animation-direction: alternate; /* Chrome, Safari, Opera */
    animation: myfirst 5s infinite;
    animation-direction: alternate;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes myfirst {
    0%   {background: red; left: 0px; top: 0px;}
    25%  {background: yellow; left: 200px; top: 0px;}
    50%  {background: blue; left: 200px; top: 200px;}
    75%  {background: green; left: 0px; top: 200px;}
    100% {background: red; left: 0px; top: 0px;}
}

@keyframes myfirst {
    0%   {background: red; left: 0px; top: 0px;}
    25%  {background: yellow; left: 200px; top: 0px;}
    50%  {background: blue; left: 200px; top: 200px;}
    75%  {background: green; left: 0px; top: 200px;}
    100% {background: red; left: 0px; top: 0px;}
}
</style>
</head>
<body>

<p><strong>Note:</strong> The animation-direction property is not supported in Internet Explorer 9 and earlier versions.</p>
<div></div>

</body>
</html>

Where 'div' is your animated object.

I hope you find this useful.

Thanks.

The tikz package seems to have what you want.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{snakes}

\begin{document}

  \begin{tikzpicture}[snake=zigzag, line before snake = 5mm, line after snake = 5mm]
    % draw horizontal line   
    \draw (0,0) -- (2,0);
    \draw[snake] (2,0) -- (4,0);
    \draw (4,0) -- (5,0);
    \draw[snake] (5,0) -- (7,0);

    % draw vertical lines
    \foreach \x in {0,1,2,4,5,7}
      \draw (\x cm,3pt) -- (\x cm,-3pt);

    % draw nodes
    \draw (0,0) node[below=3pt] {$ 0 $} node[above=3pt] {$   $};
    \draw (1,0) node[below=3pt] {$ 1 $} node[above=3pt] {$ 10 $};
    \draw (2,0) node[below=3pt] {$ 2 $} node[above=3pt] {$ 20 $};
    \draw (3,0) node[below=3pt] {$  $} node[above=3pt] {$  $};
    \draw (4,0) node[below=3pt] {$ 5 $} node[above=3pt] {$ 50 $};
    \draw (5,0) node[below=3pt] {$ 6 $} node[above=3pt] {$ 60 $};
    \draw (6,0) node[below=3pt] {$  $} node[above=3pt] {$  $};
    \draw (7,0) node[below=3pt] {$ n $} node[above=3pt] {$ 10n $};
  \end{tikzpicture}

\end{document}

I'm not too expert with tikz, but this does give a good timeline, which looks like:

A different solution (not using xaml but still quite clean I think).

class ReturnKeyTextBox : TextBox
{
    protected override void OnKeyUp(KeyEventArgs e)
    {
        base.OnKeyUp(e);
        if (e.Key == Key.Return)
            GetBindingExpression(TextProperty).UpdateSource();
    }
}

I believe this error can also be thrown if your project is targeting a framework version that is not installed on the server you are deploying to.

So multiply text values would end up in the query with single quotes around each I used =join(Parameters!Customer.Value,"','"). So after ".Value" that is comma, double-quote, single-quote, comma, single-quote, double-quote, close-bracket. simples :)

Use this pattern,

pattern = '\[P\].+?\[\/P\]'

Check here

Here's a webkit example which works for Chrome and Safari:

CSS:

::-webkit-scrollbar 
{
    width: 40px;
    background-color:#4F4F4F;
}

::-webkit-scrollbar-button:vertical:increment 
{
    height:40px;
    background-image: url(/Images/Scrollbar/decrement.png);
    background-size:39px 30px;
    background-repeat:no-repeat;
}

::-webkit-scrollbar-button:vertical:decrement 
{
    height:40px;
    background-image: url(/Images/Scrollbar/increment.png);    
    background-size:39px 30px;
    background-repeat:no-repeat;
}

Output:

This isn't mentioned in any of the other answers. If you want a value that orms (should) hydrate as boolean you can use

CONVERT(bit, 0) -- false CONVERT(bit, 1) -- true

This gives you a bit which is not a boolean. You cannot use that value in an if statement for example:

IF CONVERT(bit, 0)
BEGIN
    print 'Yay'
END

woudl not parse. You would still need to write

IF CONVERT(bit, 0) = 0

So its not terribly useful.

When testing the "ahref" method, I found that the web developer tools of Firefox and Chrome gets confused. I needed to restart the debugging after the a.click() was issued. Same happened with the FileSaver (it uses the same ahref method to actually make the saving). To work around it, I created new temporary window, added the element a into that and clicked it there.

    function download_json(dt) {
        var csv = ' var data = ';
        csv += JSON.stringify(dt, null, 3);

        var uricontent = 'data:application/octet-stream,' + encodeURI(csv);

        var newwin = window.open( "", "_blank" );
        var elem = newwin.document.createElement('a');
        elem.download = "database.js";
        elem.href = uricontent;
        elem.click();
        setTimeout(function(){ newwin.close(); }, 3000);
        
    }

WORKDIR /scripts
COPY bootstrap.sh .
RUN ./bootstrap.sh 

for (int i = 0; i < a.length; i++) {
    for (int k = 0; k < a.length; k++) {
        if (a[i] != a[k]) {
            System.out.println(a[i] + " not the same with  " + a[k + 1] + "\n");
        }
    }
}

You can start from k=1 & keep "a.length-1" in outer for loop, in order to reduce two comparisions,but that doesnt make any significant difference.

If we combine what @Hendy and @Oddysseus Ithaca contributed, we get cleaner and a more general (i.e., adaptable?) chunk of code.

    data <- read.csv("test.csv", head = F, colClasses = c(V36 = "character", V38 = "character"))                        

It's not really the python way to initialize lists like this. Anyway, you can initialize a list like this:

>>> l = [None] * 4
>>> l
[None, None, None, None]

As @Vlad from Moscow says, Take into account that value_type for std::map is defined the following way:

typedef pair<const Key, T> value_type

This then means that if you wish to replace the keyword auto with a more explicit type specifier, then you could this;

for ( const pair<const string, int> &p : table ) {
   std::cout << p.first << '\t' << p.second << std::endl;
} 

Just for understanding what auto will translate to in this case.

Variables don't take part in overrinding. Only methods do. A method call is resolved at runtime, that is, the decision to call a method is taken at runtime, but the variables are decided at compile time only. Hence that variable is called whose reference is used for calling and not of the runtime object.

Take a look at following snippet:

package com.demo;

class Bike {
  int max_speed = 90;
  public void disp_speed() {
    System.out.println("Inside bike");
 }
}

public class Honda_bikes extends Bike {
  int max_speed = 150;
  public void disp_speed() {
    System.out.println("Inside Honda");
}

public static void main(String[] args) {
    Honda_bikes obj1 = new Honda_bikes();
    Bike obj2 = new Honda_bikes();
    Bike obj3 = new Bike();

    obj1.disp_speed();
    obj2.disp_speed();
    obj3.disp_speed();

    System.out.println("Max_Speed = " + obj1.max_speed);
    System.out.println("Max_Speed = " + obj2.max_speed);
    System.out.println("Max_Speed = " + obj3.max_speed);
  }

}

When you run the code, console will show:

Inside Honda
Inside Honda
Inside bike

Max_Speed = 150
Max_Speed = 90
Max_Speed = 90

this works, and can be adapted for weeks or anyother frequency i.e. weekly, quarterly etc...

=SUMIFS(B12:B11652,A12:A11652,">="&DATE(YEAR(C12),MONTH(C12),1),A12:A11652,"<"&DATE(YEAR(C12),MONTH(C12)+1,1))

Using regexes for this purpose is the wrong approach. Since you are using python you have a really awesome library available to extract parts from HTML documents: BeautifulSoup.

The window binding refers to a built-in object provided by the browser. It represents the browser window that contains the document. Calling its addEventListener method registers the second argument (callback function) to be called whenever the event described by its first argument occurs.

<p>Some paragraph.</p>
<script>
  window.addEventListener("click", () => {
    console.log("Test");
  });
</script>

Following points should be noted before select window or document to addEventListners

1. Most of the events are same for window or document but some events like resize, and other events related to loading, unloading, and opening/closing should all be set on the window.
2. Since window has the document it is good practice to use document to handle (if it can handle) since event will hit document first.
3. Internet Explorer doesn't respond to many events registered on the window,so you will need to use document for registering event.

I didn't understand why my this didn't work but I found out that this setting is now also under the programming language itself at:

'Editor' | 'Code Style' | < your language > | 'Wrapping and Braces' | 'Right margin (columns)'

You need this:

$('.container').each(function(){  
     var $columns = $('.column',this);
     var maxHeight = Math.max.apply(Math, $columns.map(function(){
         return $(this).height();
     }).get());
     $columns.height(maxHeight);
});

Explanation

• The following snippet constructs an array of the heights:

  $columns.map(function(){
      return $(this).height();
  }).get()
  

• Math.max.apply( Math, array ) finds the maximum of array items

• $columns.height(maxHeight); sets all columns' height to maximum height.

If someone still having this problem.Try to use instead of ovverriding

 public void OnActionExecuting(ActionExecutingContext context)
    {
        try
        {

            if (!HttpContext.Current.User.Identity.IsAuthenticated)
            {
                if (!HttpContext.Current.Response.IsRequestBeingRedirected)
                {

                    context.Result = new RedirectToRouteResult(
                new RouteValueDictionary {  { "controller", "Login" }, { "action", "Index" } });
                }
            }

        }
        catch (Exception ex)
        {
               new RouteValueDictionary { { "controller", "Login" }, { "action", "Index" } });
        }

    }

<< is a binary shift, shifting 1 to the left 8 places.

4'b0001 << 1 => 4'b0010

>> is a binary right shift adding 0's to the MSB.
>>> is a signed shift which maintains the value of the MSB if the left input is signed.

4'sb1011 >>  1 => 0101
4'sb1011 >>> 1 => 1101

Three ways to indicate left operand is signed:

module shift;
  logic        [3:0] test1 = 4'b1000;
  logic signed [3:0] test2 = 4'b1000;

  initial begin
    $display("%b", $signed(test1) >>> 1 ); //Explicitly set as signed
    $display("%b", test2          >>> 1 ); //Declared as signed type
    $display("%b", 4'sb1000       >>> 1 ); //Signed constant
    $finish;
  end
endmodule

No, the methods don't need to be synchronized, and you don't need to define any methods; they are already in ConcurrentLinkedQueue, just use them. ConcurrentLinkedQueue does all the locking and other operations you need internally; your producer(s) adds data into the queue, and your consumers poll for it.

First, create your queue:

Queue<YourObject> queue = new ConcurrentLinkedQueue<YourObject>();

Now, wherever you are creating your producer/consumer objects, pass in the queue so they have somewhere to put their objects (you could use a setter for this, instead, but I prefer to do this kind of thing in a constructor):

YourProducer producer = new YourProducer(queue);

and:

YourConsumer consumer = new YourConsumer(queue);

and add stuff to it in your producer:

queue.offer(myObject);

and take stuff out in your consumer (if the queue is empty, poll() will return null, so check it):

YourObject myObject = queue.poll();

For more info see the Javadoc

EDIT:

If you need to block waiting for the queue to not be empty, you probably want to use a LinkedBlockingQueue, and use the take() method. However, LinkedBlockingQueue has a maximum capacity (defaults to Integer.MAX_VALUE, which is over two billion) and thus may or may not be appropriate depending on your circumstances.

If you only have one thread putting stuff into the queue, and another thread taking stuff out of the queue, ConcurrentLinkedQueue is probably overkill. It's more for when you may have hundreds or even thousands of threads accessing the queue at the same time. Your needs will probably be met by using:

Queue<YourObject> queue = Collections.synchronizedList(new LinkedList<YourObject>());

A plus of this is that it locks on the instance (queue), so you can synchronize on queue to ensure atomicity of composite operations (as explained by Jared). You CANNOT do this with a ConcurrentLinkedQueue, as all operations are done WITHOUT locking on the instance (using java.util.concurrent.atomic variables). You will NOT need to do this if you want to block while the queue is empty, because poll() will simply return null while the queue is empty, and poll() is atomic. Check to see if poll() returns null. If it does, wait(), then try again. No need to lock.

Finally:

Honestly, I'd just use a LinkedBlockingQueue. It is still overkill for your application, but odds are it will work fine. If it isn't performant enough (PROFILE!), you can always try something else, and it means you don't have to deal with ANY synchronized stuff:

BlockingQueue<YourObject> queue = new LinkedBlockingQueue<YourObject>();

queue.put(myObject); // Blocks until queue isn't full.

YourObject myObject = queue.take(); // Blocks until queue isn't empty.

Everything else is the same. Put probably won't block, because you aren't likely to put two billion objects into the queue.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

This will work, but the i -> i is doing some automatic unboxing which is why it "feels" strange. Either of the following will work and better explain what the compiler is doing under the hood with your original syntax:

integers.values().stream().mapToInt(i -> i.intValue()).sum();
integers.values().stream().mapToInt(Integer::intValue).sum();

You can also load the body of the script and execute it within the same process:

Set fs = CreateObject("Scripting.FileSystemObject")
Set ts = fs.OpenTextFile("script2.vbs")
body = ts.ReadAll
ts.Close
Execute body

This has been driving me crazy, especially that I couldn`t fix this without any of the solutions found online. Here is how I solved it. Can't take the credits here since this is the work of a colleague :)

Source of the problem: My initial installation of git was without auto line conversion on windows. This caused my initial commit to GLFW to be without the proper line ending.

Note: This is only a local solution. The next guy cloning the repo will still be stuck with this problem. A permanent solution can be found here: https://help.github.com/articles/dealing-with-line-endings/#re-normalizing-a-repository.

Setup: Xubuntu 12.04 Git repo with glfw project

Problem: Unable to reset glfw files. They always show as modified, regardless of what I tried.

Solved:

edit .gitattributes

Comment out the line:    # text=auto

Save the file

restore .gitattributes:   git checkout .gitattributes

eliminate all the whitespace from a string, on both ends, and in between words.

Due to the latency and lack of colors (I love color schemes :) I don't like programming on remote machines in PuTTY. So I developed this trick to work around this problem. I use it on Windows.

You will need

• 1x gVim
• 1x rsync on remote and local machines
• 1x SSH private key auth to the remote machine so you don't need to type the password
• 1x Pageant
• 1x PuTTY

Setting up remote machine

Configure rsync to make your working directory accessible. I use an SSH tunnel and only allow connections from the tunnel:

address = 127.0.0.1
hosts allow = 127.0.0.1
port = 40000
use chroot = false
[bledge_ce]
    path = /home/xplasil/divine/bledge_ce
    read only = false

Then start rsyncd: rsync --daemon --config=rsyncd.conf

Setting up local machine

Install rsync from Cygwin. Start Pageant and load your private key for the remote machine. If you're using SSH tunelling, start PuTTY to create the tunnel. Create a batch file push.bat in your working directory which will upload changed files to the remote machine using rsync:

rsync --blocking-io *.cc *.h SConstruct rsync://localhost:40001/bledge_ce

SConstruct is a build file for scons. Modify the list of files to suit your needs. Replace localhost with the name of remote machine if you don't use SSH tunelling.

Configuring Vim That is now easy. We will use the quickfix feature (:make and error list), but the compilation will run on the remote machine. So we need to set makeprg:

set makeprg=push\ &&\ plink\ -batch\ [email protected]\ \"cd\ /home/xplasil/divine/bledge_ce\ &&\ scons\ -j\ 2\"

This will first start the push.bat task to upload the files and then execute the commands on remote machine using SSH (Plink from the PuTTY suite). The command first changes directory to the working dir and then starts build (I use scons).

The results of build will show conviniently in your local gVim errors list.

Typically this is the directory where your app (java) was started (working dir). "Typically" because it can be changed, eg when you run an app with Runtime.exec(String[] cmdarray, String[] envp, File dir)

Not as complicated as it sounds.... Just leave the duplicate primary key out of your query.... this works for me !

INSERT INTO
  Content(
    `status`,
    content_category,
    content_type,
    content_id,
    user_id,
    title,
    description,
    content_file,
    content_url,
    tags,
    create_date,
    edit_date,
    runs
  )
SELECT `status`,
  content_category,
  content_type,
  content_id,
  user_id,
  title,
  description,
  content_file,
  content_url,
  tags,
  create_date,
  edit_date,
  runs
FROM
  Content_Images

Yes, your compiler is expecting void *. Just cast them to void *.

/* for instance... */
printf("The value of s is: %p\n", (void *) s);
printf("The direction of s is: %p\n", (void *) &s);

I too got this problem and all solutions given above either failed or were not applicable due to client webservice restrictions.

For this, I added an iframe in my page which resided in the client;s server. So when we post our data to the iframe and the iframe then posts it to the webservice. Hence the cross-domain referencing is eliminated.

We added a 2-way origin check to confirm only authorized page posts data to and from the iframe.

Hope it helps

<iframe style="display:none;" id='receiver' name="receiver" src="https://iframe-address-at-client-server">
 </iframe>

//send data to iframe
var hiddenFrame = document.getElementById('receiver').contentWindow;
hiddenFrame.postMessage(JSON.stringify(message), 'https://client-server-url');

//The iframe receives the data using the code:
window.onload = function () {
    var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
    var eventer = window[eventMethod];
    var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
    eventer(messageEvent, function (e) {
        var origin = e.origin;
        //if origin not in pre-defined list, break and return
        var messageFromParent = JSON.parse(e.data);
        var json = messageFromParent.data;

        //send json to web service using AJAX   
        //return the response back to source
        e.source.postMessage(JSON.stringify(aJAXResponse), e.origin);
    }, false);
}

That is the source code for Ants' SCP task. The code in the "execute" method is where the nuts and bolts of it are. This should give you a fair idea of what is required. It uses JSch i believe.

Alternatively you could also directly execute this Ant task from your java code.

I got that message after attached an attribute to a method

[webMethod]
public void DoSomething()
{
}

But the correct way was this:

[webMethod()] // Note the Parentheses 
public void DoSomething()
{
}

I want to create a 2D array that each cell is an ArrayList!

If you want to create a 2D array of ArrayList.Then you can do this :

ArrayList[][] table = new ArrayList[10][10];
table[0][0] = new ArrayList(); // add another ArrayList object to [0,0]
table[0][0].add(); // add object to that ArrayList

I used this import:

import java.util.Date;

And declared my variable like this:

Date studentEnrollementDate;

The python timedelta library should do what you need. A timedelta is returned when you subtract two datetime instances.

import datetime
dt_started = datetime.datetime.utcnow()

# do some stuff

dt_ended = datetime.datetime.utcnow()
print((dt_ended - dt_started).total_seconds())

I assume that you haven't set the TableName property of the DataTable, for example via constructor:

var tbl = new DataTable("dtImage");

If you don't provide a name, it will be automatically created with "Table1", the next table will get "Table2" and so on.

Then the solution would be to provide the TableName and then check with Contains(nameOfTable).

To clarify it: You'll get an ArgumentException if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException if there's already a DataTable in the DataSet with the same name(not case-sensitive).

The simplest solutions seem to overlook that UTC time will be used, including highly up-voted ones. Below is a streamlined, ES6, non-jQuery version of a couple of existing answers:

const today = (function() {
    const now = new Date();
    const month = (now.getMonth() + 1).toString().padStart(2, '0');
    const day = now.getDate().toString().padStart(2, '0');
    return `${now.getFullYear()}-${month}-${day}`;
})();
console.log(today); // as of posting this answer: 2019-01-24

If you want to define your ItemReader instance and your Step instance in a single JavaConfig class. You can use the @StepScope and the @Value annotations such as:

@Configuration
public class ContributionCardBatchConfiguration {

   private static final String WILL_BE_INJECTED = null;

   @Bean
   @StepScope
   public FlatFileItemReader<ContributionCard> contributionCardReader(@Value("#{jobParameters['fileName']}")String contributionCardCsvFileName){

     ....
   }

   @Bean
   Step ingestContributionCardStep(ItemReader<ContributionCard> reader){
         return stepBuilderFactory.get("ingestContributionCardStep")
                 .<ContributionCard, ContributionCard>chunk(1)
                 .reader(contributionCardReader(WILL_BE_INJECTED))
                 .writer(contributionCardWriter())
                 .build();
    }
}

The trick is to pass a null value to the itemReader since it will be injected through the @Value("#{jobParameters['fileName']}") annotation.

This works flawlessly @ 2019

.marketing-panel  {
    background-image: url("../images/background.jpg");
    background-repeat: no-repeat;
    background-size: auto;
    background-position: center;
}

i don't know what mistakes i did while implementing the above solutions, bt they were unsuccessful for me

txtDeck.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override       
    public void onFocusChange(View v, boolean hasFocus) {
        txtDeck.setText("");
    }
});

This works for me,

Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:

Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M

When I use SourceTree to do the stuff, it will spit out this message.
The message that I encountered:

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree submodule update --init --recursive
No submodule mapping found in .gitmodules for path 'SampleProject/SampleProject'
Completed with errors, see above

My scenario is I misapplied the project directory the contains .git folder.
SourceTree regarded this folder as git submodule, but actually not.

My solution is use command line to remove it.

$ git rm -r SampleProject --cached
$ git commit -m "clean up folders"

remove the garbage in git and keep it clean.
