I had the same error:
"Syntax error, unrecognized expression: // "
It is known bug at JQuery, so i needed to think on workaround solution,
What I did is:
I changed "script" tag to "div"
and added at angular this code
and the error is gone...

app.run(['$templateCache', function($templateCache) {
    var url = "survey-input.html";
    content = angular.element(document.getElementById(url)).html()
    $templateCache.put(url, content);
}]);

Use a double not:

!!1 = true;

!!0 = false;

obj.isChecked = !!parseInt(obj.isChecked);

My suggestion:

using System.Linq;

string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

I know this is years later but I ran into the same problem. The solution I found was to change the window title in main.cpp. I guess once the w.show(); is called the window title can no longer be changed. In my case I just wanted the title to reflect the current directory and it works.

int main(int argc, char *argv[]) 
{
QApplication a(argc, argv);
MainWindow w;
w.setWindowTitle(QDir::currentPath());
w.show();

return a.exec();
}

For windows users:

Go to Task Manager directly with CTRL+SHIFT+ESC key combination.

Kill the "java.exe" processes by right clicking and selecting "End Task".

You could also do:

Regions.query({}, function(response) {
    $scope.regions = response;
    // Do stuff that depends on $scope.regions here
});

CSS 3

divContainer input[type="text"] {
    width:150px;
}

CSS2 add a class "text" to the text inputs then in your css

.divContainer.text{
    width:150px;
}

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

For MySql take in mind that it's not a good idea to write camelcase. For example if the schema is like that:

CREATE TABLE IF NOT EXISTS `task`(
    `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
    `teaching_hours` DECIMAL(5,2) DEFAULT NULL,
    `isActive` BOOLEAN DEFAULT FALSE,
    `is_validated` BOOLEAN DEFAULT FALSE,
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

You must be very careful cause isActive column will translate to isactive. So in your Entity class is should be like this:

 @Basic
 @Column(name = "isactive", nullable = true)
 public boolean isActive() {
     return isActive;
 }
 public void setActive(boolean active) {
     isActive = active;
 }

That was my problem at least that got me your error

This has nothing to do with MySql which is case insensitive, but rather is a naming strategy that spring will use to translate your tables. For more refer to this post

If you want to handle your webapp's timeout with an apache load balancer, you first have to understand the different meaning of timeout. I try to condense the discussion I found here: http://apache-http-server.18135.x6.nabble.com/mod-proxy-When-does-a-backend-be-considered-as-failed-td5031316.html :

It appears that mod_proxy considers a backend as failed only when the transport layer connection to that backend fails. Unless failonstatus/failontimeout is used. ...

So, setting failontimeout is necessary for apache to consider a timeout of the webapp (e.g. served by tomcat) as a fail (and consecutively switch to the hot spare server). For the proper configuration, note the following misconfiguration:

ProxyPass / balancer://localbalance/ failontimeout=on timeout=10 failonstatus=50

This is a misconfiguration because:

You are defining a balancer here, so the timeout parameter relates to the balancer (like the two others). However for a balancer, the timeout parameter is not a connection timeout (like the one used with BalancerMember), but the maximum time to wait for a free worker/member (e.g. when all the workers are busy or in error state, the default being to not wait).

So, a proper configuration is done like this

1. set timeout at the BalanceMember level:

 <Proxy balancer://mycluster>
     BalancerMember http://member1:8080/svc timeout=6 
 ... more BalanceMembers here
</Proxy>

2. set the failontimeout on the balancer

ProxyPass /svc balancer://mycluster failontimeout=on

Restart apache.

By default, Blade {{ }} statements are automatically sent through PHP's htmlspecialchars function to prevent XSS attacks. If you do not want your data to be escaped, you may use the following syntax:

According to the doc, you must do the following to render your html in your Blade files:

{!! $text !!}

Be very careful when echoing content that is supplied by users of your application. You should typically use the escaped, double curly brace syntax to prevent XSS attacks when displaying user supplied data.

On Mac (and Linux I think), after you have created your AVD, you can make an alias: alias run-android='~/Library/Android/sdk/tools/emulator -avd ${YOUR_AVD_NAME} &'

Note: the execution of the alias will not lock your terminal, if you want that, just remove the last '&'.

Run emulator it self will give you an error because he expect that, in your current position, you have: /emulator/qemu/${YOUR_PATFORM}/qemu-system-x86_64' to start the emulator.

Here's a quick one-line hack that I occasionally use to temporarily turn on log4j debug logging in a JUnit test:

Logger.getRootLogger().setLevel(Level.DEBUG);

or if you want to avoid adding imports:

org.apache.log4j.Logger.getRootLogger().setLevel(
      org.apache.log4j.Level.DEBUG);

Note: this hack doesn't work in log4j2 because setLevel has been removed from the API, and there doesn't appear to be equivalent functionality.

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

Go to Tools -> Java Platforms. There, click on Add Platform, point it to C:\Program Files (x86)\Java\jdk1.6.0_25. You can either set the another JDK version or remove existing versions.

Another solution suggested in the oracle (sun) site is,

netbeans.exe --jdkhome "C:\Program Files\jdk1.6.0_20"

I tried this on 6.9.1. You may change the JDK per project as well. You need to set the available JDKs via Java Platforms dialog. Then, go to Run -> Set Project Configuration -> Customize. After that, in the opened Dialog box go to Build -> Compile. Set the version.

Before starting python, you can do in bash

export MPLBACKEND=TkAgg

I may be wrong, but I believe I've seen a list of previous SQL queries in the session file for phpmyadmin sessions

If you want one row for each filename, reflecting a specific states and listing the most recent date then this is your friend:

select filename ,
       status   ,
       max_date = max( dates )
from some_table t
group by filename , status
having status = '<your-desired-status-here>'

Easy!

Use the quotemeta function:

$text_to_search = "example text with [foo] and more";
$search_string = quotemeta "[foo]";

print "wee" if ($text_to_search =~ /$search_string/);

Have a look at numpy.split:

>>> a = numpy.array([1,2,3,4])
>>> numpy.split(a, 2)
[array([1, 2]), array([3, 4])]

GCC has a switch called

-fno-inline-small-functions

So use that when invoking gcc. But the side effect is that all other small functions are also non-inlined.

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

You need to add the _token in your form i.e

{{ form_row(form._token) }}

As of now your form is missing the CSRF token field. If you use the twig form functions to render your form like form(form) this will automatically render the CSRF token field for you, but your code shows you are rendering your form with raw HTML like <form></form>, so you have to manually render the field.

Or, simply add {{ form_rest(form) }} before the closing tag of the form.

According to docs

This renders all fields that have not yet been rendered for the given form. It's a good idea to always have this somewhere inside your form as it'll render hidden fields for you and make any fields you forgot to render more obvious (since it'll render the field for you).

form_rest(view, variables)

Probably something like this:

original_list = dictionary.get('C1')
new_list = []
for item in original_list:
  new_list.append(item+10)
dictionary['C1'] = new_list

Here is a cleaner way of getting the first key:

var object = {
    foo1: 'value of the first property "foo1"',
    foo2: { /* stuff2 */},
    foo3: { /* stuff3 */}
};

let [firstKey] = Object.keys(object)

console.log(firstKey)
console.log(object[firstKey])

let dateString  = '13-02-2021' //date string in dd-mm-yyyy format

let dateArray = dateString.split("-");
//dateArray[2] equals to 2021
//dateArray[1] equals to 02
//dateArray[0] equals to 13

// using template literals below

let dateObj = new Date(`${dateArray[2]}-${dateArray[1]}-${dateArray[0]}`);

// dateObj equals to Sat Feb 13 2021 05:30:00 GMT+0530 (India Standard Time)

//I'm from India so its showing GMT+0530

P.S : Always refer docs for basics, MDN or DevDocs

This solved the issue for me:

So I was running 300 PHP processes simulatenously and was getting a rate of between 60 - 90 per second (my process involves 3x queries). I upped it to 400 and this fell to about 40-50 per second. I dropped it to 200 and am back to between 60 and 90!

So my advice to anyone with this problem is experiment with running less than more and see if it improves. There will be less memory and CPU being used so the processes that do run will have greater ability and the speed may improve.

if you post a file from mobile device or other

    byte[] fileData = null;
    using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
    {
        fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
    }

There is a helpful function in the psych package.

You should try the following implementation:

psych::describeBy(data$dependentvariable, group = data$groupingvariable)

Use 10.0.2.2 to access your actual machine.

As you've learned, when you use the emulator, localhost (127.0.0.1) refers to the device's own loopback service, not the one on your machine as you may expect.

You can use 10.0.2.2 to access your actual machine, it is an alias set up to help in development.

Check this out:

plt.hist(myarray, density = True)

setting aria-hidden to false and toggling it on element.show() worked for me.

e.g

<span aria-hidden="true">aria text</span>

$(span).attr('aria-hidden', 'false');
$(span).show();

and when hiding back

$(span).attr('aria-hidden', 'true');
$(span).hide();

I recently used Spring Security 3.0 for this (combined with Wicket btw), and am quite happy with it. Here's a good thorough tutorial and documentation. Also take a look at this tutorial which gives a good explanation of the hashing/salting/decoding setup for Spring Security 2.

Here you can set hidden's value at onchange event of dropdown list :

$('#myDropDown').bind('change', function () {
  $('#myHidden').val('setted value');
});

your hidden and drop down list :

<input type="hidden" id="myHidden" />

<select id="myDropDown">
   <option value="opt 1">Option 1</option>
   <option value="opt 2">Option 2</option>
   <option value="opt 3">Option 3</option>
</ select>

I had a similar problem, I ran my tests disabling the reuse of forks like this

mvn clean test -DreuseForks=false

and the problem disappeared. The downside is that the overall test execution time will be longer, that's why you may want to do this from the command line only if necessary

document.cookie="MYBIGCOOKIE=1";

Your cookies would look like:

"MYBIGCOOKIE=1; PHPSESSID=d76f00dvgrtea8f917f50db8c31cce9"

first of all read all cookies:

var read_cookies = document.cookie;

then split all cookies with ";":

var split_read_cookie = read_cookies.split(";");

then use for loop to read each value. Into loop each value split again with "=":

for (i=0;i<split_read_cookie.length;i++){
    var value=split_read_cookie[i];
    value=value.split("=");
    if(value[0]=="MYBIGCOOKIE" && value[1]=="1"){
        alert('it is 1');
    }
}

Create the intent like this:

Intent smsIntent = new Intent(android.content.Intent.ACTION_VIEW);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address","your desired phoneNumber");         
smsIntent.putExtra("sms_body","your desired message");
smsIntent.setFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(smsIntent);

By passing parameters by reference to function.

Examples:

 void incInt(int *y)
 {
     (*y)++;  // Increase the value of 'x', in main, by one.
 }

Also by using global variables but it is not recommended.

Example:

int a=0;

void main(void)
{
    //Anything you want to code.
}

The answer to this depends very much on how your specific Java compiler optimizes the bytecode it generates. Strings are immutable and, theoretically, each "+" operation can create a new one. But, your compiler almost certainly optimizes away interim steps in building long strings. It's entirely possible that both lines of code above generate the exact same bytecode.

The only real way to know is to test the code iteratively in your current environment. Write a QD app that concatenates strings both ways iteratively and see how they time out against each other.

In my case, the following code founds to be useful. Place below code in Web.config file under Views folder.

<configSections>

  <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
   <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
   <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
  </sectionGroup>

</configSections>

Once the code is updated, make sure to clean and rebuild the solution. I hope this will help you out!

I have a really stupid use case for why I got this error. Originally I was printing my data > file.txt

Then I changed my mind, and decided to use open("file.txt", "w") instead. But when I called python, I left > file.txt .....

If you want to get stored procedures using specific column only, you can use try this query:

SELECT DISTINCT Name
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%CreatedDate%';

If you want to get stored procedures using specific column of table, you can use below query :

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%';

You didn't mention the fancy indexing capabilities of dataframes, e.g.:

>>> df = pd.DataFrame({"class":[1,1,1,2,2], "value":[1,2,3,4,5]})
>>> df[df["class"]==1].sum()
class    3
value    6
dtype: int64
>>> df[df["class"]==1].sum()["value"]
6
>>> df[df["class"]==1].count()["value"]
3

You could replace df["class"]==1by another condition.

Button click event only.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
        <script language="javascript" type="text/javascript">
            $(document).ready(function () {
                $("#btnext").click(function () {                    
                    window.open("HTMLPage.htm", "PopupWindow", "width=600,height=600,scrollbars=yes,resizable=no");
                });
            });
</script>

A more general approach:

if ( ($("body").hasClass("homepage") || $("body").hasClass("contact")) && (theLanguage == 'en-gb') )   {

       // Do something

}

From crtdbg.h (and many other headers):

#ifndef NULL
#ifdef __cplusplus
#define NULL    0
#else
#define NULL    ((void *)0)
#endif
#endif

Therefore NULL is 0, at least on the Windows platform. So no, not that I know of.

It is possible to make a "ghost-like" IFrame that acts like it was not there.

See http://codecopy.wordpress.com/2013/02/22/ghost-iframe-crossdomain-iframe-resize/

Basically you use the event system parent.postMessage(..) described in https://developer.mozilla.org/en-US/docs/DOM/window.postMessage

This works an all modern browsers!

Though it is an old question, it is still a valid one.

Expected behavior:

• Show selected file name after upload.
• Do not do anything if the user clicks Cancel.
• Show the file name even when the user selects the same file.

Code with a demonstration:

<!DOCTYPE html>
<html>

<head>
  <title>File upload event</title>
</head>

<body>
  <form action="" method="POST" enctype="multipart/form-data">
    <input type="file" name="userFile" id="userFile"><br>
    <input type="submit" name="upload_btn" value="upload">
  </form>
  <script type="text/javascript">
    document.getElementById("userFile").onchange = function(e) {
      alert(this.value);
      this.value = null;
    }
  </script>
</body>

</html>

Explanation:

• The onchange event handler is used to handle any change in file selection event.
• The onchange event is triggered only when the value of an element is changed. So, when we select the same file using the input field the event will not be triggered. To overcome this, I set this.value = null; at the end of the onchange event function. It sets the file path of the selected file to null. Thus, the onchange event is triggered even at the time of the same file selection.

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

You can do it using streams map function like below, get result in new stream for further processing.

Stream<Fruit> newFruits = fruits.stream().map(fruit -> {fruit.name+="s"; return fruit;});
        newFruits.forEach(fruit->{
            System.out.println(fruit.name);
        });

Since Jan 2019, GitHub allows private repositories for up to three collaborators.

Previous answer:

Here is the comparison for free plans listed by tree main Git Cloud based solutions:

Here is the comparison for paid plans listed by tree main Git Cloud based solutions:

Conclusion:

I'm not seeing people mentioning GitLab here, but it seems like the best free private plan for me. I myself am using it with no problems.

GitHub: If you have a student account or want to pay for $7 monthly, GitHub has the biggest community and you can take advantage of it's public repositories, forks, etc.

Bitbucket: If you use other products from Atlassian like Jira or Confluence, Bitbucket works great with them.

GitLab: Everything that I care about (free private repository, number of private repositories, number of collaborators, etc.) are offered for free. This seems like the best choice for me.

You could include the 'ncurses' library, and use getch() instead of getchar().

There is no need to use AS, just use:

SELECT table1.price Table1 Price, table2.price Table2 Price, .....

Just to make your script more readable, maybe use this proc:

DELIMITER ;;

DROP PROCEDURE IF EXISTS printf;
CREATE PROCEDURE printf(thetext TEXT)
BEGIN

  select thetext as ``;

 END;

;;

DELIMITER ;

Now you can just do:

call printf('Counting products that have missing short description');

<video width="1000px" loop="true" autoplay="autoplay" controls muted></video> worked for me

Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

You can avoid this problem by

• accessing the lazy collection within a transaction.
• Initalizing the collection using Hibernate.initialize(obj);
• Fetch the collection in another transaction
• Use Fetch profiles to select lazy/non-lazy fetching runtime
• Set fetch to non-lazy (which is generally not recommended)

Further I would recommend looking at the related links to your right where this question has been answered many times before. Also see Hibernate lazy-load application design.

As far as i know %d means decadic which is number without decimal point. if you want to load double value, use %lf conversion (long float). for printf your values are wrong for same reason, %d is used only for integer (and possibly chars if you know what you are doing) numbers.

Example:

double a,b;
printf("--------\n"); //seperate lines
scanf("%lf",&a);
printf("--------\n"); 
scanf("%lf",&b);
printf("%lf %lf",a,b);

You need to use callbacks. That's how asynchronous IO works. Btw sys.puts is deprecated

Is this code snippet work for you?

if (!count($_SESSION)>0) {
    session_start();
}

Make sure you provide a number, typically a double is used. Math.Round can take 1-3 arguments, the first argument is the variable you wish to round, the second is the number of decimal places and the third is the type of rounding.

double pay = 200 + bonus;
double pay = Math.Round(pay);
// Rounds to nearest even number, rounding 0.5 will round "down" to zero because zero is even
double pay = Math.Round(pay, 2, MidpointRounding.ToEven);
// Rounds up to nearest number
double pay = Math.Round(pay, 2, MidpointRounding.AwayFromZero);

Please use

.FirstOrDefault()

because if in the first row of the result there is no info this instruction goes to the default info.

Try this:

<meta http-equiv="refresh" content="5;URL= your url">

or

<meta http-equiv="refresh" content="5">  

Do you mean that you've got code like

if(map.containsKey(key)) doSomethingWith(map.get(key))

all over the place ? Then you should simply check whether map.get(key) returned null and that's it. By the way, HashMap doesn't throw exceptions for missing keys, it returns null instead. The only case where containsKey is needed is when you're storing null values, to distinguish between a null value and a missing value, but this is usually considered bad practice.

As many folks already alluded to, this is a 32 vs. 64 bit problem for both Eclipse and Java. You cannot mix up 32 and 64 bit. Since Eclipse doesn't use JAVA_HOME, you'll likely have to alter your PATH prior to launching Eclipse to ensure you are using not only the appropriate version of Java, but also if 32 or 64 bit (or modify the INI file as Jayath noted).

If you are installing Eclipse from a company-share, you should ensure you can tell which Eclipse version you are unzipping, and unzip to the appropriate Program Files directory to help keep track of which is which, then change the PATH (either permanently via (Windows) Control Panel -> System or set PATH=/path/to/32 or 64bit/java/bin;%PATH% (maybe create a batch file if you don't want to set it in your system and/or user environment variables). Remember, 32-bit is in Program files (x86).

If unsure, just launch Eclipse, if you get the error, change your PATH to the other 'bit' version of Java, and then try again. Then move the Eclipse directory to the appropriate Program Files directory.

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

The simplest solution is to add modal dialog styles to the top of the page or import css with this code:

<style>
    .modal-dialog {
    position:absolute;
    top:50% !important;
    transform: translate(0, -50%) !important;
    -ms-transform: translate(0, -50%) !important;
    -webkit-transform: translate(0, -50%) !important;
    margin:auto 50%;
    width:40%;
    height:40%;
    }
</style>

Modal declaration:

    <div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
            <div class="modal-body">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

Modal usage:

<a data-toggle="modal" data-target="#exampleModalCenter">
 ...
</a>

I'm not an Oracle user (well, lately anyhow), BUT...

In most databases (and in precise language), a date doesn't include a time. Having a date doesn't imply that you are denoting a specific second on that date. Generally if you want a time as well as a date, that's called a timestamp.

Go to the traffic section inside graphs. Here you can find how many unique visitors you have. Other than this there is no other way to know who exactly viewed your account.

The scope <scope>provided</scope> gives you an opportunity to tell that the jar would be available at runtime, so do not bundle it. It does not mean that you do not need it at compile time, hence maven would try to download that.

Now I think, the below maven artifact do not exist at all. I tries searching google, but not able to find. Hence you are getting this issue.

Change groupId to <groupId>net.sourceforge.ant4x</groupId> to get the latest jar.

<dependency>
  <groupId>net.sourceforge.ant4x</groupId>
  <artifactId>ant4x</artifactId>
  <version>${net.sourceforge.ant4x-version}</version>
  <scope>provided</scope>
</dependency>

Another solution for this problem is:

1. Run your own maven repo.
2. download the jar
3. Install the jar into the repository.
4. Add a code in your pom.xml something like:

Where http://localhost/repo is your local repo URL:

<repositories>
    <repository>
        <id>wmc-central</id>
        <url>http://localhost/repo</url>
    </repository>
    <-- Other repository config ... -->
</repositories>

First: As it currently stands, the $User variable does not have a .Users property. In your code, $User simply represents one line (the "current" line in the foreach loop) from the text file.

$getmembership = Get-ADUser $User -Properties MemberOf | Select -ExpandProperty memberof

Secondly, I do not believe you can query an entire forest with one command. You will have to break it down into smaller chunks:

1. Query forest for list of domains
2. Call Get-ADUser for each domain (you may have to specify alternate credentials via the -Credential parameter

Thirdly, to get a list of groups that a user is a member of:

$User = Get-ADUser -Identity trevor -Properties *;
$GroupMembership = ($user.memberof | % { (Get-ADGroup $_).Name; }) -join ';';

# Result:
Orchestrator Users Group;ConfigMgr Administrators;Service Manager Admins;Domain Admins;Schema Admins

Fourthly: To get the final, desired string format, simply add the $User.Name, a semicolon, and the $GroupMembership string together:

$User.SamAccountName + ';' + $GroupMembership;

You may:

Find: (\w) Replace With: \L$1

Or select the text, ctrl+K+L.

replace:true is Deprecated

From the Docs:

replace ([DEPRECATED!], will be removed in next major release - i.e. v2.0)

specify what the template should replace. Defaults to false.

• true - the template will replace the directive's element.
• false - the template will replace the contents of the directive's element.

-- AngularJS Comprehensive Directive API

From GitHub:

Caitp-- It's deprecated because there are known, very silly problems with replace: true, a number of which can't really be fixed in a reasonable fashion. If you're careful and avoid these problems, then more power to you, but for the benefit of new users, it's easier to just tell them "this will give you a headache, don't do it".

-- AngularJS Issue #7636

Update

Note: replace: true is deprecated and not recommended to use, mainly due to the issues listed here. It has been completely removed in the new Angular.

Issues with replace: true

• Attribute values are not merged
• Directives are not deduplicated before compilation
• transclude: element in the replace template root can have unexpected effects

For more information, see

• AngularJS $compile Service API Reference - Issues with replace:true

You can get the "computed" styles of any element.

IE uses something called "currentStyle", Firefox (and I assume other "standard compliant" browsers) uses "defaultView.getComputedStyle".

You'll need to write a cross browser function to do this, or use a good Javascript framework like prototype or jQuery (search for "getStyle" in the prototype javascript file, and "curCss" in the jquery javascript file).

That said if you need the height or width you should probably use element.offsetHeight and element.offsetWidth.

The value returned is Null, so if I have Javascript that needs to know the width of something to do some logic (I increase the width by 1%, not to a specific value)

Mind, if you add an inline style to the element in question, it can act as the "default" value and will be readable by Javascript on page load, since it is the element's inline style property:

<div style="width:50%">....</div>

You should override Equals and GetHashCode meaningfully, in this case to compare the ID:

public class LinqTest
{
    public int id { get; set; }
    public string value { get; set; }

    public override bool Equals(object obj)
    {
        LinqTest obj2 = obj as LinqTest;
        if (obj2 == null) return false;
        return id == obj2.id;
    }

    public override int GetHashCode()
    {
        return id;
    }
}

Now you can use Distinct:

List<LinqTest> uniqueIDs = myList.Distinct().ToList();

I got this same error working in Eclipse with Maven with the additional information

schema_reference.4: Failed to read schema document 'https://maven.apache.org/xsd/maven-4.0.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

This was after copying in a new controller and it's interface from a Thymeleaf example. Honestly, no matter how careful I am I still am at a loss to understand how one is expected to figure this out. On a (lucky) guess I right clicked the project, clicked Maven and Update Project which cleared up the issue.

I used those following steps:

git rm -r --cached .
git add --all .
git commit -a -m "Versioning untracked files"
git push origin master

For me is a simple solution

This solution works for Integer length size =1.

Integer input = 9; Character.valueOf((char) input.toString().charAt(0))

if size >1 we need to use for loop and iterate through.

git merge --squash <feature branch> is a good option .The "git commit" tells you all feature branch commit message with your choice to keep it .

For less commit merge .

git merge do x times --git reset HEAD^ --soft then git commit .

Risk - deleted files may come back .

When you define concatenation you need to use an ALIAS for the new column if you want to order on it combined with DISTINCT Some Ex with sql 2008

--this works 

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName 
    from SalesLT.Customer c 
    order by FullName

--this works too

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) 
    from SalesLT.Customer c 
    order by 1

-- this doesn't 

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName 
    from SalesLT.Customer c 
    order by c.FirstName, c.LastName

-- the problem the DISTINCT needs an order on the new concatenated column, here I order on the singular column
-- this works

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) 
        as FullName, CustomerID 
        from SalesLT.Customer c 

order by 1, CustomerID

-- this doesn't

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName 
     from SalesLT.Customer c 
      order by 1, CustomerID

You can use IntEnum:

from enum import IntEnum

class Color(IntEnum):
   RED = 1
   BLUE = 2


print(int(Color.RED))   # prints 1

To get list of the ints:

enum_list = list(map(int, Color))
print(enum_list) # prints [1, 2]

In general, you're looking for the "Except" extension.

var rejectStatus = GenerateRejectStatuses();
var fullList = GenerateFullList();
var rejectList = fullList.Where(i => rejectStatus.Contains(i.Status));
var filteredList = fullList.Except(rejectList);

In this example, GenerateRegectStatuses() should be the list of statuses you wish to reject (or in more concrete terms based on your example, a List<int> of IDs)

Necromancing.

If it's to load a dynamic list of scripts, write the scripts into an attribute, such as data-main, e.g. <script src="scriptloader.js" data-main="file1.js,file2.js,file3.js,etc." ></script>
and do a element.getAttribute("data-main").split(',')

such as

var target = document.currentScript || (function() {
  var scripts = document.getElementsByTagName('script');
  // Note: this is for IE as IE doesn't support currentScript
  // this does not work if you have deferred loading with async
  // e.g. <script src="..." async="async" ></script>
  // https://web.archive.org/web/20180618155601/https://www.w3schools.com/TAgs/att_script_async.asp
  return scripts[scripts.length - 1];
})();

target.getAttribute("data-main").split(',')

to obtain the list.

Hoping to help anyone. :)

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"

Things have been changed after conda 4.6.

Programs "Anaconda Prompt" and "Anaconda Powershell" expose the command conda for you automatically. Find them in your startup menu.

If you don't wanna use the prompts above and try to make conda available in a normal cmd.exe and a Powershell. Read the following content.

Expose conda in Every Shell

The purpose of the following content is to make command conda available both in cmd.exe and Powershell on Windows.

If you have already checked "Add Anaconda to my PATH environment variable" during Anaconda installation, skip step 1.

1. If Anaconda is installed for the current use only, add %USERPROFILE%\Anaconda3\condabin (I mean condabin, not Scripts) into the environment variable PATH (the user one). If Anaconda is installed for all users on your machine, add C:\ProgramData\Anaconda3\condabin into PATH.

   How do I set system environment variables on Windows?

2. Open a new Powershell, run the following command once to initialize conda.

   conda init
   

These steps make sure the conda command is exposed into your cmd.exe and Powershell.

Extended Reading: conda init from Conda 4.6

Caveat: Add the new \path\to\anaconda3\condabin but not \path\to\anaconda3\Scripts into your PATH. This is a big change introduced in conda 4.6.

Activation script initialization fron conda 4.6 release log

Conda 4.6 adds extensive initialization support so that more shells than ever before can use the new conda activate command. For more information, read the output from conda init –help We’re especially excited about this new way of working, because removing the need to modify PATH makes Conda much less disruptive to other software on your system.

In the old days, \path\to\anaconda3\Scripts is the one to be put into your PATH. It exposes command conda and the default Python from "base" environment at the same time.

After conda 4.6, conda related commands are separated into condabin. This makes it possible to expose ONLY command conda without activating the Python from "base" environment.

The transparent parts mostly have RGBA value (0,0,0,0). Since the JPG has no transparency, the jpeg value is set to (0,0,0), which is black.

Around the circular icon, there are pixels with nonzero RGB values where A = 0. So they look transparent in the PNG, but funny-colored in the JPG.

You can set all pixels where A == 0 to have R = G = B = 255 using numpy like this:

import Image
import numpy as np

FNAME = 'logo.png'
img = Image.open(FNAME).convert('RGBA')
x = np.array(img)
r, g, b, a = np.rollaxis(x, axis = -1)
r[a == 0] = 255
g[a == 0] = 255
b[a == 0] = 255
x = np.dstack([r, g, b, a])
img = Image.fromarray(x, 'RGBA')
img.save('/tmp/out.jpg')

Note that the logo also has some semi-transparent pixels used to smooth the edges around the words and icon. Saving to jpeg ignores the semi-transparency, making the resultant jpeg look quite jagged.

A better quality result could be made using imagemagick's convert command:

convert logo.png -background white -flatten /tmp/out.jpg

To make a nicer quality blend using numpy, you could use alpha compositing:

import Image
import numpy as np

def alpha_composite(src, dst):
    '''
    Return the alpha composite of src and dst.

    Parameters:
    src -- PIL RGBA Image object
    dst -- PIL RGBA Image object

    The algorithm comes from http://en.wikipedia.org/wiki/Alpha_compositing
    '''
    # http://stackoverflow.com/a/3375291/190597
    # http://stackoverflow.com/a/9166671/190597
    src = np.asarray(src)
    dst = np.asarray(dst)
    out = np.empty(src.shape, dtype = 'float')
    alpha = np.index_exp[:, :, 3:]
    rgb = np.index_exp[:, :, :3]
    src_a = src[alpha]/255.0
    dst_a = dst[alpha]/255.0
    out[alpha] = src_a+dst_a*(1-src_a)
    old_setting = np.seterr(invalid = 'ignore')
    out[rgb] = (src[rgb]*src_a + dst[rgb]*dst_a*(1-src_a))/out[alpha]
    np.seterr(**old_setting)    
    out[alpha] *= 255
    np.clip(out,0,255)
    # astype('uint8') maps np.nan (and np.inf) to 0
    out = out.astype('uint8')
    out = Image.fromarray(out, 'RGBA')
    return out            

FNAME = 'logo.png'
img = Image.open(FNAME).convert('RGBA')
white = Image.new('RGBA', size = img.size, color = (255, 255, 255, 255))
img = alpha_composite(img, white)
img.save('/tmp/out.jpg')

Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.

import pickle

class MyUser(object):
    def __init__(self,name):
        self.name = name

user = MyUser('Peter')

print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'

with open(filename,'wb') as file_object:
    file_object.write(serialized)

with open(filename,'rb') as file_object:
    raw_data = file_object.read()

deserialized = pickle.loads(raw_data)


print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)
print("------------")

Without a third party function:

string format = "Hi {0}".replace('{0}', name)

With multiple params:

string format = "Hi {0} {1}".replace('{0}', name).replace('{1}', lastname)

If you are defining your function:

function test() {};

Then, this is equivalent to:

window.test = function() {}  /* (in the browser) */

So spyOn(window, 'test') should work.

If that is not, you should also be able to:

test = jasmine.createSpy();

If none of those are working, something else is going on with your setup.

I don't think your fakeElement technique works because of what is going on behind the scenes. The original globalMethod still points to the same code. What spying does is proxy it, but only in the context of an object. If you can get your test code to call through the fakeElement it would work, but then you'd be able to give up global fns.

The default, unnamed instance always gets port 1433 for TCP. UDP port 1434 is used by the SQL Browser service to allow named instances to be located. In SQL Server 2000 the first instance to be started took this role.

Non-default instances get their own dynamically-allocated port, by default. If necessary, for example to configure a firewall, you can set them explicitly. If you don't want to enable or allow access to SQL Browser, you have to either include the instance's port number in the connection string, or set it up with the Alias tab in cliconfg (SQL Server Client Network Utility) on each client machine.

For more information see SQL Server Browser Service on MSDN.

Sure is easy with pure JS, just do this, work for fixed and animated HTML 5 panels too, i made and try this code and it works for any brower (include IE 8):

<script type="text/javascript">
    function fGetCSSProperty(s, e) {
        try { return s.currentStyle ? s.currentStyle[e] : window.getComputedStyle(s)[e]; }
        catch (x) { return null; } 
    }
    function fGetOffSetParent(s) {
        var a = s.offsetParent || document.body;

        while (a && a.tagName && a != document.body && fGetCSSProperty(a, 'position') == 'static')
            a = a.offsetParent;
        return a;
    }
    function GetPosition(s) {
        var b = fGetOffSetParent(s);

        return { Left: (b.offsetLeft + s.offsetLeft), Top: (b.offsetTop + s.offsetTop) };
    }    
</script>

The easiest way is to set some variable in the file that calls include, such as

$including = true;

Then in the file that's being included, check for the variable

if (!$including) exit("direct access not permitted");

set "html" option to true if you want to have html into tooltip. Actual html is determined by option "title" (link's title attribute shouldn't be set)

$('#example1').tooltip({placement: 'bottom', title: '<p class="testtooltip">par</p>', html: true});

Live sample

One simple use case when reverting change:
1. Use reset if you want to undo staging of a modified file.
2. Use checkout if you want to discard changes to unstaged file/s.

Your printf needs a format string:

printf("%d\n", x);

This reference page gives details on how to use printf and related functions.

$(document).ready(function(){

    $('#mySelect').append("<option>BMW</option>")

})

jasonmp85 is right about passing a different array to String.format. The size of an array can't be changed once constructed, so you'd have to pass a new array instead of modifying the existing one.

Object newArgs = new Object[args.length+1];
System.arraycopy(args, 0, newArgs, 1, args.length);
newArgs[0] = extraVar; 
String.format(format, extraVar, args);

XDocument xdoc = XDocument.Load(path_to_xml);
var word = xdoc.Elements("word")
               .SingleOrDefault(w => (string)w.Element("category") == "verb");

This query will return whole word XElement. If there is more than one word element with category verb, than you will get an InvalidOperationException. If there is no elements with category verb, result will be null.

I had the same problem and I found out that if you add the URL param ?v=3 you won't get the warning message anymore:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3"></script>

Reproduction online

As pointed out in the comments by @Zia Ul Rehman Mughal

Turns out specifying this means you are referring to old frozen version 3.0 not the latest version. Frozen old versions are not updated with bug fixes or anything. But this is good to mention though. https://developers.google.com/maps/documentation/javascript/versions#the-frozen-version

Update 07-Jun-2016

This solution doesn't work anymore.

In C++-11 you can do:

std::vector<int> v = {0, 1, 2, 3, 4, 5};
for (auto i : v)
{
   // access by value, the type of i is int
   std::cout << i << ' ';
}
std::cout << '\n';

See here for variations: https://en.cppreference.com/w/cpp/language/range-for

I recommend that you use the standard packages email and smtplib together to send email. Please look at the following example (reproduced from the Python documentation). Notice that if you follow this approach, the "simple" task is indeed simple, and the more complex tasks (like attaching binary objects or sending plain/HTML multipart messages) are accomplished very rapidly.

# Import smtplib for the actual sending function
import smtplib

# Import the email modules we'll need
from email.mime.text import MIMEText

# Open a plain text file for reading.  For this example, assume that
# the text file contains only ASCII characters.
with open(textfile, 'rb') as fp:
    # Create a text/plain message
    msg = MIMEText(fp.read())

# me == the sender's email address
# you == the recipient's email address
msg['Subject'] = 'The contents of %s' % textfile
msg['From'] = me
msg['To'] = you

# Send the message via our own SMTP server, but don't include the
# envelope header.
s = smtplib.SMTP('localhost')
s.sendmail(me, [you], msg.as_string())
s.quit()

For sending email to multiple destinations, you can also follow the example in the Python documentation:

# Import smtplib for the actual sending function
import smtplib

# Here are the email package modules we'll need
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart

# Create the container (outer) email message.
msg = MIMEMultipart()
msg['Subject'] = 'Our family reunion'
# me == the sender's email address
# family = the list of all recipients' email addresses
msg['From'] = me
msg['To'] = ', '.join(family)
msg.preamble = 'Our family reunion'

# Assume we know that the image files are all in PNG format
for file in pngfiles:
    # Open the files in binary mode.  Let the MIMEImage class automatically
    # guess the specific image type.
    with open(file, 'rb') as fp:
        img = MIMEImage(fp.read())
    msg.attach(img)

# Send the email via our own SMTP server.
s = smtplib.SMTP('localhost')
s.sendmail(me, family, msg.as_string())
s.quit()

As you can see, the header To in the MIMEText object must be a string consisting of email addresses separated by commas. On the other hand, the second argument to the sendmail function must be a list of strings (each string is an email address).

So, if you have three email addresses: [email protected], [email protected], and [email protected], you can do as follows (obvious sections omitted):

to = ["[email protected]", "[email protected]", "[email protected]"]
msg['To'] = ",".join(to)
s.sendmail(me, to, msg.as_string())

the ",".join(to) part makes a single string out of the list, separated by commas.

From your questions I gather that you have not gone through the Python tutorial - it is a MUST if you want to get anywhere in Python - the documentation is mostly excellent for the standard library.

He who is Shy^* gave you the germ of an answer, but only the germ. The basic technique for converting a value into a string in the C pre-processor is indeed via the '#' operator, but a simple transliteration of the proposed solution gets a compilation error:

#define TEST_FUNC test_func
#define TEST_FUNC_NAME #TEST_FUNC

#include <stdio.h>
int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

The syntax error is on the 'puts()' line - the problem is a 'stray #' in the source.

In section 6.10.3.2 of the C standard, 'The # operator', it says:

Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.

The trouble is that you can convert macro arguments to strings -- but you can't convert random items that are not macro arguments.

So, to achieve the effect you are after, you most certainly have to do some extra work.

#define FUNCTION_NAME(name) #name
#define TEST_FUNC_NAME  FUNCTION_NAME(test_func)

#include <stdio.h>

int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

I'm not completely clear on how you plan to use the macros, and how you plan to avoid repetition altogether. This slightly more elaborate example might be more informative. The use of a macro equivalent to STR_VALUE is an idiom that is necessary to get the desired result.

#define STR_VALUE(arg)      #arg
#define FUNCTION_NAME(name) STR_VALUE(name)

#define TEST_FUNC      test_func
#define TEST_FUNC_NAME FUNCTION_NAME(TEST_FUNC)

#include <stdio.h>

static void TEST_FUNC(void)
{
    printf("In function %s\n", TEST_FUNC_NAME);
}

int main(void)
{
    puts(TEST_FUNC_NAME);
    TEST_FUNC();
    return(0);
}

In your receiving intent you need to do:

Intent i = getIntent();  
stock_list = i.getStringArrayListExtra("stock_list");

The way you have it you've just created a new empty intent without any extras.

If you only have a single extra you can condense this down to:

stock_list = getIntent().getStringArrayListExtra("stock_list");

in /etc/my.cnf:

Good work on server with 256MB Memory.

You should really use the Literal ASP.NET control for that.

There are several ways to do this. Both are very simple. Each of the examples works great. You can copy it into your project and test it.

The first method is preferable, the second is a bit outdated, but so far it works too.

1) Solution 1

// File - app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

}

2) Solution 2. It is old way but still works.

        );
    }
}

I found the following command to run from command line:

vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt

Thanks to mcandre, the answer is:

#python3
from inspect import currentframe, getframeinfo

frameinfo = getframeinfo(currentframe())

print(frameinfo.filename, frameinfo.lineno)

your line raising the error is here:

comment = Comment.objects.get(pk=comment_id)

you try to access a non-existing comment.

from django.shortcuts import get_object_or_404

comment = get_object_or_404(Comment, pk=comment_id)

Instead of having an error on your server, your user will get a 404 meaning that he tries to access a non existing resource.

Ok up to here I suppose you are aware of this.

Some users (and I'm part of them) let tabs running for long time, if users are authorized to delete data, it may happens. A 404 error may be a better error to handle a deleted resource error than sending an email to the admin.

Other users go to addresses from their history, (same if data have been deleted since it may happens).

It's netstat -ano|findstr port no

Result would show process id in last column

Sometimes it is not eligible to set height to pixel values. However, it is possible to show vertical scrollbar through setting height of div to 100% and overflow to auto.

Let me show an example:

<div id="content" style="height: 100%; overflow: auto">
  <p>some text</p>
  <ul>
    <li>text</li>
    .....
    <li>text</li>
</div>

Well in my case the data which I wanted to render contained an Object inside that of the array so due to this it was giving error, so for other people out there please check your data also once and if it contains an object, you need to convert it to array to print all of its values or if you need a specific value then use.

My data :

body: " d fvsdv"

photo: "http://res.cloudinary.com/imvr7/image/upload/v1591563988/hhanfhiyalwnv231oweg.png"

postedby: {_id: "5edbf948cdfafc4e38e74081", name: "vit"} //this is the object I am talking about.

title: "c sx "

__v: 0

_id: "5edd56d7e64a9e58acfd499f"

proto: Object

To Print only a single value

<h5>{item.postedby.name}</h5>

you can use:

(//@lang)[1]

these means you get all attributes nodes with name equal to "lang" and get the first one.

Javascript:

// Check
document.getElementById("checkbox").checked = true;

// Uncheck
document.getElementById("checkbox").checked = false;

jQuery (1.6+):

// Check
$("#checkbox").prop("checked", true);

// Uncheck
$("#checkbox").prop("checked", false);

jQuery (1.5-):

// Check
$("#checkbox").attr("checked", true);

// Uncheck
$("#checkbox").attr("checked", false);

The simplest way to remove duplicates whilst preserving order is to use collections.OrderedDict (Python 2.7+).

from collections import OrderedDict
d = OrderedDict()
for x in mylist:
    d[x] = True
print d.iterkeys()

An easy way would be to iterate over the items in the array in a loop.

for (var i = 0; i < arrayLength; i++) {
 // (string) Compare the given string with myArray[i]
 // if it matches store/save i and exit the loop.
}

There would definitely be better ways but for small number of items this should be blazing fast. Btw this is javascript but same method should work in almost every programming language.

I also had the same problem, I searched for the answers many places. I got many similar answers to change the number of process/service handlers. But I thought, what if I forgot to reset it back?

Then I tried using Thread.sleep() method after each of my connection.close();.

I don't know how, but it's working at least for me.

If any one wants to try it out and figure out how it's working then please go ahead. I would also like to know it as I am a beginner in programming world.

In my case I use chrono and c function localtime_r which is thread-safe (in opposition to std::localtime).

#include <iostream>
#include <chrono>
#include <ctime>
#include <time.h>
#include <iomanip>


int main() {
  std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
  std::time_t currentTime = std::chrono::system_clock::to_time_t(now);
  std::chrono::milliseconds now2 = std::chrono::duration_cast<std::chrono::milliseconds>(now.time_since_epoch());
  struct tm currentLocalTime;
  localtime_r(&currentTime, &currentLocalTime);
  char timeBuffer[80];
  std::size_t charCount { std::strftime( timeBuffer, 80,
                                         "%b %d %T",
                                          &currentLocalTime)
                         };

  if (charCount == 0) return -1;

  std::cout << timeBuffer << "." << std::setfill('0') << std::setw(3) << now2.count() % 1000 << std::endl;
  return 0;
}

This should get you access to applicationContext from anywhere allowing you to get applicationContext anywhere that can use it; Toast, getString(), sharedPreferences, etc.

 */
public class ApplicationContextSingleton {
    private static PrefsContextSingleton mInstance;
    private Context context;

    public static ApplicationContextSingleton getInstance() {
        if (mInstance == null) mInstance = getSync();

Initialize the Singleton in your Application subclass:

package com.domain.packagename;

import android.app.Application;

/**
 * Created by Versa on 25.08.15.
 */
public class mApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        ApplicationContextSingleton.getInstance().initialize(this);
    }
}

If I´m not wrong, this gives you a hook to applicationContext everywhere, call it with ApplicationContextSingleton.getInstance.getApplicationContext(); You shouldn´t need to clear this at any point, as when application closes, this goes with it anyway.

Remember to update AndroidManifest.xml to use this Application subclass:

<?xml version="1.0" encoding="utf-8"?>

<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.domain.packagename"
    >

<application
    android:allowBackup="true"
    android:name=".mApplication" <!-- This is the important line -->
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:icon="@drawable/app_icon"
    >

Please let me know if you see anything wrong here, thank you. :)

You are not getting value of $id=$_GET['id'];

And you are using it (before it gets initialised).

Use php's in built isset() function to check whether the variable is defied or not.

So, please update the line to:

$id = isset($_GET['id']) ? $_GET['id'] : '';

Unix

The commands env, set, and printenv display all environment variables and their values. env and set are also used to set environment variables and are often incorporated directly into the shell. printenv can also be used to print a single variable by giving that variable name as the sole argument to the command.

In Unix, the following commands can also be used, but are often dependent on a certain shell.

export VARIABLE=value  # for Bourne, bash, and related shells
setenv VARIABLE value  # for csh and related shells

You can have a look at this at

You can add the tag as a property for the Fragment arguments. It will be automatically restored if the fragment is destroyed and then recreated by the OS.

Example:-

    final Bundle args = new Bundle();
    args.putString("TAG", "my tag");
    fragment.setArguments(args);

PHP 5.4+

$n = 12.343;
intval($n); // 12
explode('.', number_format($n, 1))[1]; // 3
explode('.', number_format($n, 2))[1]; // 34
explode('.', number_format($n, 3))[1]; // 343
explode('.', number_format($n, 4))[1]; // 3430

Use the below function and use days paramater to get the date daysAhead/daysBehind just pass parameter as positive for future date or negative for previous dates:

+ (NSDate *) getDate:(NSDate *)fromDate daysAhead:(NSUInteger)days
{
    NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
    dateComponents.day = days;
    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDate *previousDate = [calendar dateByAddingComponents:dateComponents
                                                     toDate:fromDate
                                                    options:0];
    [dateComponents release];
    return previousDate;
}

you can use ls -1

ls -l will also do the work

Yes:

float[] values = {0.1f, 0.2f, 0.3f};

This syntax is only permissible in an initializer. You cannot use it in an assignment, where the following is the best you can do:

values = new float[3];

or

values = new float[] {0.1f, 0.2f, 0.3f};

Trying to find a reference in the language spec for this, but it's as unreadable as ever. Anyone else find one?

After upgrading lots of packages (Spyder 3 to 4, Keras and Tensorflow and lots of their dependencies), I had the same problem today! I cannot figure out what happened; but the (conda-based) virtual environment that kept using Spyder 3 did not have the problem. Although installing tkinter or changing the backend, via matplotlib.use('TkAgg) as shown above, or this nice post on how to change the backend, might well resolve the problem, I don't see these as rigid solutions. For me, uninstalling matplotlib and reinstalling it was magic and the problem was solved.

pip uninstall matplotlib

... then, install

pip install matplotlib

From all the above, this could be a package management problem, and BTW, I use both conda and pip, whenever feasible.

You should not define global variables in header files. You can declare them as extern in header file and define them in a .c source file.

(Note: In C, int i; is a tentative definition, it allocates storage for the variable (= is a definition) if there is no other definition found for that variable in the translation unit.)

Use the ssh2 functions. Anything you'd do via an exec() call can be done directly using these functions, saving you a lot of connections and shell invocations.

You vs Technology http://www.weblogcartoons.com/cartoons/you-v-tech.gif

You can parameterise it and pass gradle clean build -Pprokey=goodbye

task choiceMyMainClass(type: JavaExec) {
     group = "Execution"
    description = "Run Option main class with JavaExecTask"
    classpath = sourceSets.main.runtimeClasspath

    if (project.hasProperty('prokey')){
        if (prokey == 'hello'){
            main = 'com.sam.home.HelloWorld'
        } 
        else if (prokey == 'goodbye'){
            main = 'com.sam.home.GoodBye'
        }
    } else {
            println 'Invalid value is enterrd';

       // println 'Invalid value is enterrd'+ project.prokey;
    }

You can safely delete the WSDL cache files. If you wish to prevent future caching, use:

ini_set("soap.wsdl_cache_enabled", 0);

or dynamically:

$client = new SoapClient('http://somewhere.com/?wsdl', array('cache_wsdl' => WSDL_CACHE_NONE) );

1. markers is not a JSON object. It is a normal JavaScript object.
2. Read about the data: option:

   Data to be sent to the server. It is converted to a query string, if not already a string.

If you want to send the data as JSON, you have to encode it first:

data: {markers: JSON.stringify(markers)}

jQuery does not convert objects or arrays to JSON automatically.

But I assume the error message comes from interpreting the response of the service. The text you send back is not JSON. JSON strings have to be enclosed in double quotes. So you'd have to do:

return "\"received markers\"";

I'm not sure if your actual problem is sending or receiving the data.

I have installed python 3.7.4. First, I tried python in my command prompt. It was saying that 'Python is not recognized command......'. Then I tried 'py' command and it works.

My sample command is:

py hacker.py

Just type ma and press Ctrl + Space, you will get an option for it.

It's not possible to create a many-to-many relationship with a customized join table. In a many-to-many relationship EF manages the join table internally and hidden. It's a table without an Entity class in your model. To work with such a join table with additional properties you will have to create actually two one-to-many relationships. It could look like this:

public class Member
{
    public int MemberID { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }

    public virtual ICollection<MemberComment> MemberComments { get; set; }
}

public class Comment
{
    public int CommentID { get; set; }
    public string Message { get; set; }

    public virtual ICollection<MemberComment> MemberComments { get; set; }
}

public class MemberComment
{
    [Key, Column(Order = 0)]
    public int MemberID { get; set; }
    [Key, Column(Order = 1)]
    public int CommentID { get; set; }

    public virtual Member Member { get; set; }
    public virtual Comment Comment { get; set; }

    public int Something { get; set; }
    public string SomethingElse { get; set; }
}

If you now want to find all comments of members with LastName = "Smith" for example you can write a query like this:

var commentsOfMembers = context.Members
    .Where(m => m.LastName == "Smith")
    .SelectMany(m => m.MemberComments.Select(mc => mc.Comment))
    .ToList();

... or ...

var commentsOfMembers = context.MemberComments
    .Where(mc => mc.Member.LastName == "Smith")
    .Select(mc => mc.Comment)
    .ToList();

Or to create a list of members with name "Smith" (we assume there is more than one) along with their comments you can use a projection:

var membersWithComments = context.Members
    .Where(m => m.LastName == "Smith")
    .Select(m => new
    {
        Member = m,
        Comments = m.MemberComments.Select(mc => mc.Comment)
    })
    .ToList();

If you want to find all comments of a member with MemberId = 1:

var commentsOfMember = context.MemberComments
    .Where(mc => mc.MemberId == 1)
    .Select(mc => mc.Comment)
    .ToList();

Now you can also filter by the properties in your join table (which would not be possible in a many-to-many relationship), for example: Filter all comments of member 1 which have a 99 in property Something:

var filteredCommentsOfMember = context.MemberComments
    .Where(mc => mc.MemberId == 1 && mc.Something == 99)
    .Select(mc => mc.Comment)
    .ToList();

Because of lazy loading things might become easier. If you have a loaded Member you should be able to get the comments without an explicit query:

var commentsOfMember = member.MemberComments.Select(mc => mc.Comment);

I guess that lazy loading will fetch the comments automatically behind the scenes.

Edit

Just for fun a few examples more how to add entities and relationships and how to delete them in this model:

1) Create one member and two comments of this member:

var member1 = new Member { FirstName = "Pete" };
var comment1 = new Comment { Message = "Good morning!" };
var comment2 = new Comment { Message = "Good evening!" };
var memberComment1 = new MemberComment { Member = member1, Comment = comment1,
                                         Something = 101 };
var memberComment2 = new MemberComment { Member = member1, Comment = comment2,
                                         Something = 102 };

context.MemberComments.Add(memberComment1); // will also add member1 and comment1
context.MemberComments.Add(memberComment2); // will also add comment2

context.SaveChanges();

2) Add a third comment of member1:

var member1 = context.Members.Where(m => m.FirstName == "Pete")
    .SingleOrDefault();
if (member1 != null)
{
    var comment3 = new Comment { Message = "Good night!" };
    var memberComment3 = new MemberComment { Member = member1,
                                             Comment = comment3,
                                             Something = 103 };

    context.MemberComments.Add(memberComment3); // will also add comment3
    context.SaveChanges();
}

3) Create new member and relate it to the existing comment2:

var comment2 = context.Comments.Where(c => c.Message == "Good evening!")
    .SingleOrDefault();
if (comment2 != null)
{
    var member2 = new Member { FirstName = "Paul" };
    var memberComment4 = new MemberComment { Member = member2,
                                             Comment = comment2,
                                             Something = 201 };

    context.MemberComments.Add(memberComment4);
    context.SaveChanges();
}

4) Create relationship between existing member2 and comment3:

var member2 = context.Members.Where(m => m.FirstName == "Paul")
    .SingleOrDefault();
var comment3 = context.Comments.Where(c => c.Message == "Good night!")
    .SingleOrDefault();
if (member2 != null && comment3 != null)
{
    var memberComment5 = new MemberComment { Member = member2,
                                             Comment = comment3,
                                             Something = 202 };

    context.MemberComments.Add(memberComment5);
    context.SaveChanges();
}

5) Delete this relationship again:

var memberComment5 = context.MemberComments
    .Where(mc => mc.Member.FirstName == "Paul"
        && mc.Comment.Message == "Good night!")
    .SingleOrDefault();
if (memberComment5 != null)
{
    context.MemberComments.Remove(memberComment5);
    context.SaveChanges();
}

6) Delete member1 and all its relationships to the comments:

var member1 = context.Members.Where(m => m.FirstName == "Pete")
    .SingleOrDefault();
if (member1 != null)
{
    context.Members.Remove(member1);
    context.SaveChanges();
}

This deletes the relationships in MemberComments too because the one-to-many relationships between Member and MemberComments and between Comment and MemberComments are setup with cascading delete by convention. And this is the case because MemberId and CommentId in MemberComment are detected as foreign key properties for the Member and Comment navigation properties and since the FK properties are of type non-nullable int the relationship is required which finally causes the cascading-delete-setup. Makes sense in this model, I think.

You should try something like $_SERVER['HTTP_REFERER'].

Why do you need to state both 'x' and 'y' before the ':'?

You could actually in some situations(when you have only one argument) do not put the x and y before ":".

>>> flist = []
>>> for i in range(3):
...     flist.append(lambda : i)

but the i in the lambda will be bound by name, so,

>>> flist[0]()
2
>>> flist[2]()
2
>>>

different from what you may want.

A carriage return (\r) makes the cursor jump to the first column (begin of the line) while the newline (\n) jumps to the next line and eventually to the beginning of that line. So to be sure to be at the first position within the next line one uses both.

Check your random_page_cost

This problem typically happens when the estimated cost of an index scan is too high and doesn't correctly reflect reality. You may need to lower the random_page_cost configuration parameter to fix this. From the Postgres documentation:

Reducing this value [...] will cause the system to prefer index scans; raising it will make index scans look relatively more expensive.

You can do a quick test whether this will actually make Postgres use the index:

EXPLAIN <query>;              # Uses sequential scan
SET random_page_cost = 1;
EXPLAIN <query>;              # May use index scan now

You can restore the default value with SET random_page_cost = DEFAULT; again.

Background

Index scans require non-sequential disk page fetches. Postgres uses random_page_cost to estimate the cost of such non-sequential fetches in relation to sequential fetches. The default value is 4.0, thus assuming an average cost factor of 4 compared to sequential fetches (taking caching effects into account).

The problem however is that this default value is unsuitable in the following important real-life scenarios:

1) Solid-state drives

As per the documentation:

Storage that has a low random read cost relative to sequential, e.g. solid-state drives, might be better modeled with a lower value for random_page_cost, e.g., 1.1.

This slide from a speak at PostgresConf 2018 also says that random_page_cost should be set to something between 1.0 and 2.0 for solid-state drives.

2) Cached data

If the required index data is already cached in RAM, an index scan will always be significantly faster than a sequential scan. The documentation says:

If your data is likely to be completely in cache, [...] decreasing random_page_cost can be appropriate.

The problem is that you of course can't easily know whether the relevant data is already cached. However, if a specific index is frequently used, and if the system has sufficient RAM, then data is likely to be cached eventually, and random_page_cost should be set to a lower value. You'll have to experiment with different values and see what works for you.

You might also want to use the pg_prewarm extension for explicit data caching.

If you only need to replace characters in one specific column, somehow regex=True and in place=True all failed, I think this way will work:

data["column_name"] = data["column_name"].apply(lambda x: x.replace("characters_need_to_replace", "new_characters"))

lambda is more like a function that works like a for loop in this scenario. x here represents every one of the entries in the current column.

The only thing you need to do is to change the "column_name", "characters_need_to_replace" and "new_characters".

You can simulate a readonly select box using the CSS pointer-events property:

select[readonly]
{
    pointer-events: none;
}

The HTML tabindex property will also prevent it from being selected by keyboard tabbing:

<select tabindex="-1">

select[readonly]_x000D_
{_x000D_
    pointer-events: none;_x000D_
}_x000D_
_x000D_
_x000D_
/* irrelevent styling */_x000D_
_x000D_
*_x000D_
{_x000D_
  box-sizing: border-box;_x000D_

_x000D_
*[readonly]_x000D_

  background: #fafafa;_x000D_
  border: 1px solid #ccc;_x000D_

_x000D_
input, select_x000D_
{_x000D_
  display:block;_x000D_
  width: 20rem;_x000D_
  padding: 0.5rem;_x000D_
  margin-bottom: 1rem;_x000D_
}

<form>_x000D_
  <input type="text" value="this is a normal text box">_x000D_
  <input type="text" readonly value="this is a readonly text box">_x000D_
  <select readonly tabindex="-1">_x000D_
    <option>This is a readonly select box</option>_x000D_
    <option>Option 2</option>_x000D_
  </select>_x000D_
  <select>_x000D_
    <option>This is a normal select box</option>_x000D_
    <option>Option 2</option>_x000D_
  </select>_x000D_
</form>

The delete operator allows you to remove a property from an object.

The following examples all do the same thing.

// Example 1
var key = "Cow";
delete thisIsObject[key]; 

// Example 2
delete thisIsObject["Cow"];

// Example 3
delete thisIsObject.Cow;

If you're interested, read Understanding Delete for an in-depth explanation.

enter the values as 0:mm:ss and format as [m]:ss

as this is now in the mins & seconds, simple arithmetic will allow you to calculate your statistics

Try to change the port number in application.yaml (or application.properties) to something else.

For me only following is working:

primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
    @Override
    public void handle(WindowEvent event) {

        Platform.exit();

        Thread start = new Thread(new Runnable() {
            @Override
            public void run() {
                //TODO Auto-generated method stub
                system.exit(0);     
            }
        });

        start.start();
    }
});

You can use the dir step, example:

dir("folder") {
    sh "pwd"
}

The folder can be relative or absolute path.

Try getting the element with the ID and check if the return value is null:

document.getElementById('some_nonexistent_id') === null

If you're using jQuery, you can do:

$('#some_nonexistent_id').length === 0

This is my simple solution:

String secToTime(int sec) {
    int seconds = sec % 60;
    int minutes = sec / 60;
    if (minutes >= 60) {
        int hours = minutes / 60;
        minutes %= 60;
        if( hours >= 24) {
            int days = hours / 24;
            return String.format("%d days %02d:%02d:%02d", days,hours%24, minutes, seconds);
        }
        return String.format("%02d:%02d:%02d", hours, minutes, seconds);
    }
    return String.format("00:%02d:%02d", minutes, seconds);
}

Test Results:

Result: 00:00:36 - 36
Result: 01:00:07 - 3607
Result: 6313 days 12:39:05 - 545488745

LOESS is a very good approach, as Dirk said.

Another option is using Bezier splines, which may in some cases work better than LOESS if you don't have many data points.

Here you'll find an example: http://rosettacode.org/wiki/Cubic_bezier_curves#R

# x, y: the x and y coordinates of the hull points
# n: the number of points in the curve.
bezierCurve <- function(x, y, n=10)
    {
    outx <- NULL
    outy <- NULL

    i <- 1
    for (t in seq(0, 1, length.out=n))
        {
        b <- bez(x, y, t)
        outx[i] <- b$x
        outy[i] <- b$y

        i <- i+1
        }

    return (list(x=outx, y=outy))
    }

bez <- function(x, y, t)
    {
    outx <- 0
    outy <- 0
    n <- length(x)-1
    for (i in 0:n)
        {
        outx <- outx + choose(n, i)*((1-t)^(n-i))*t^i*x[i+1]
        outy <- outy + choose(n, i)*((1-t)^(n-i))*t^i*y[i+1]
        }

    return (list(x=outx, y=outy))
    }

# Example usage
x <- c(4,6,4,5,6,7)
y <- 1:6
plot(x, y, "o", pch=20)
points(bezierCurve(x,y,20), type="l", col="red")

Look at the DefaultTableModel for a simple model that you can use:

http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html

This extends the AbstractTableModel, but should be sufficient for basic purposes. You can always extend AbstractTableModel and create your own. Make sure you set it on the JTable as well.

http://java.sun.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html

Look at the basic Sun tutorial for more information on using the JTable with the table model:

http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#data

I think the easiest way would be

var items = $('img, style, ...'), itemslen = items.length;

items.bind('load', function(){ 
    itemslen--;
    if (!itemlen) // Do stuff here
});

EDIT, to be a little crazy:

var items = $('a, abbr, acronym, address, applet, area, audio, b, base, ' + 
    'basefont, bdo, bgsound, big, body, blockquote, br, button, canvas, ' + 
    'caption, center, cite, code, col, colgroup, comment, custom, dd, del, ' +
    'dfn, dir, div, dl, document, dt, em, embed, fieldset, font, form, frame, ' +
    'frameset, head, hn, hr, html, i, iframe, img, input, ins, isindex, kbd, ' +
    'label, legend, li, link, listing, map, marquee, media, menu, meta, ' +
    'nextid, nobr, noframes, noscript, object, ol, optgroup, option, p, ' +
    'param, plaintext, pre, q, rt, ruby, s, samp, script, select, small, ' + 
    'source, span, strike, strong, style, sub, sup, table, tbody, td, ' + 
    'textarea, tfoot, th, thead, title, tr, tt, u, ul, var, wbr, video, ' + 
    'window, xmp'), itemslen = items.length;

items.bind('load', function(){ 
    itemslen--;
    if (!itemlen) // Do stuff here
});

Use following code to show menu instead go to href addres

function show_more_menu(e) {_x000D_
  if( !confirm(`Go to ${e.target.href} ?`) ) e.preventDefault();_x000D_
}

<a href='more.php' onclick="show_more_menu(event)"> More >>> </a>

Tieme put a lot of effort into his excellent answer, but I think the core of the OP's question is how these technologies relate to PHP rather than how each technology works.

PHP is the most used language in web development besides the obvious client side HTML, CSS, and Javascript. Yet PHP has 2 major issues when it comes to real-time applications:

1. PHP started as a very basic CGI. PHP has progressed very far since its early stage, but it happened in small steps. PHP already had many millions of users by the time it became the embed-able and flexible C library that it is today, most of whom were dependent on its earlier model of execution, so it hasn't yet made a solid attempt to escape the CGI model internally. Even the command line interface invokes the PHP library (libphp5.so on Linux, php5ts.dll on Windows, etc) as if it still a CGI processing a GET/POST request. It still executes code as if it just has to build a "page" and then end its life cycle. As a result, it has very little support for multi-thread or event-driven programming (within PHP userspace), making it currently unpractical for real-time, multi-user applications.

Note that PHP does have extensions to provide event loops (such as libevent) and threads (such as pthreads) in PHP userspace, but very, very, few of the applications use these.

2. PHP still has significant issues with garbage collection. Although these issues have been consistently improving (likely its greatest step to end the life cycle as described above), even the best attempts at creating long-running PHP applications require being restarted on a regular basis. This also makes it unpractical for real-time applications.

PHP 7 will be a great step to fix these issues as well, and seems very promising as a platform for real-time applications.

I tried everything to fix this issue on my windows 7 machine like

Reinstalling and rebuilding npm

At last, I fixed this small configuration setting issue by wasting my entire day.

How I resolved this issue

Removing my project specific configurations in global .npmrc at location like drive:/Windows/Users/../.npmrc

Original answer:

import os

for filename in os.listdir(directory):
    if filename.endswith(".asm") or filename.endswith(".py"): 
         # print(os.path.join(directory, filename))
        continue
    else:
        continue

Python 3.6 version of the above answer, using os - assuming that you have the directory path as a str object in a variable called directory_in_str:

import os

directory = os.fsencode(directory_in_str)
    
for file in os.listdir(directory):
     filename = os.fsdecode(file)
     if filename.endswith(".asm") or filename.endswith(".py"): 
         # print(os.path.join(directory, filename))
         continue
     else:
         continue

Or recursively, using pathlib:

from pathlib import Path

pathlist = Path(directory_in_str).glob('**/*.asm')
for path in pathlist:
     # because path is object not string
     path_in_str = str(path)
     # print(path_in_str)

• Use rglob to replace glob('**/*.asm') with rglob('*.asm')
  • This is like calling Path.glob() with '**/' added in front of the given relative pattern:

from pathlib import Path

pathlist = Path(directory_in_str).rglob('*.asm')
for path in pathlist:
     # because path is object not string
     path_in_str = str(path)
     # print(path_in_str)

Do you really need to load it from a file? If you place it along your classes (in WEB-INF/classes) you can get an InputStream to it using the class loader:

InputStream csv = 
   SomeClassInTheSamePackage.class.getResourceAsStream("filename.csv");

Try this...

function Test()
{
    var s1 = new StopWatch();

    s1.Start();        

    // Do something.

    s1.Stop();

    alert( s1.ElapsedMilliseconds );
} 

// Create a stopwatch "class." 
StopWatch = function()
{
    this.StartMilliseconds = 0;
    this.ElapsedMilliseconds = 0;
}  

StopWatch.prototype.Start = function()
{
    this.StartMilliseconds = new Date().getTime();
}

StopWatch.prototype.Stop = function()
{
    this.ElapsedMilliseconds = new Date().getTime() - this.StartMilliseconds;
}

1) You should require your file with ZipArchive file.

require 'path/to/file/ZipArchive.php';

2) Or use __autoload method of class. In PHP 5 it is a greate method __autoload().

function __autoload($class_name) {
    require_once $class_name . '.php';
}

$obj  = new MyClass1(); // creating an object without require.

http://www.php.net/manual/en/language.oop5.autoload.php

Easiest way to get text from the user:

EditText Variable1 = findViewById(R.id.enter_name);
String Variable2 = Variable1.getText().toString();

I found a solution like this where a word, "Dark", would be shortened to just "D" on a smaller screen width. Basically you just make the font size of the original content 0 and have the shortened form as a pseudo element.

In this example the change happens on hover instead:

span {_x000D_
  font-size: 12px;_x000D_
}_x000D_
_x000D_
span:after {_x000D_
  display: none;_x000D_
  font-size: 12px;_x000D_
  content: 'D';_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
span:hover {_x000D_
  font-size: 0px;_x000D_
}_x000D_
_x000D_
span:hover:after {_x000D_
  display: inline;_x000D_
}

<span>Dark</span>

yum update

helped me out. After I had

wget: symbol lookup error: wget: undefined symbol: psl_latest

Two things to observe here:

1. Constructor is called whenever an object is created of that class.
2. ngOnInit called once the component is created.

Both have different usability.

Just use Date.parse() which returns a Number, then use new Date() to parse it:

var thedate = new Date(Date.parse("2011-07-14 11:23:00"));

UPDATE:

New link for the icons image size by apple.

https://developer.apple.com/ios/human-interface-guidelines/graphics/image-size-and-resolution/

Yes it's True here it is Apple provide Official documentation regarding icon's or image size

you have to set images for iPhone6 and iPhone6+

For iPhone 6:

750 x 1334 (@2x) for portrait

1334 x 750 (@2x) for landscape

For iPhone 6 Plus:

1242 x 2208 (@3x) for portrait

2208 x 1242 (@3x) for landscape

For more info regarding Images and it's resolution this is best ever helpful post

For setting images size for controls you can set 1x @2x and @3x like following:

Since you've already looked into strtok just continue down the same path and split your string using space (' ') as a delimiter, then use something as realloc to increase the size of the array containing the elements to be passed to execvp.

See the below example, but keep in mind that strtok will modify the string passed to it. If you don't want this to happen you are required to make a copy of the original string, using strcpy or similar function.

char    str[]= "ls -l";
char ** res  = NULL;
char *  p    = strtok (str, " ");
int n_spaces = 0, i;


/* split string and append tokens to 'res' */

while (p) {
  res = realloc (res, sizeof (char*) * ++n_spaces);

  if (res == NULL)
    exit (-1); /* memory allocation failed */

  res[n_spaces-1] = p;

  p = strtok (NULL, " ");
}

/* realloc one extra element for the last NULL */

res = realloc (res, sizeof (char*) * (n_spaces+1));
res[n_spaces] = 0;

/* print the result */

for (i = 0; i < (n_spaces+1); ++i)
  printf ("res[%d] = %s\n", i, res[i]);

/* free the memory allocated */

free (res);

res[0] = ls
res[1] = -l
res[2] = (null)

Update: I should have probably started with this as your projects are SNAPSHOTs. It is part of the SNAPSHOT semantics that Maven will check for updates on each build. Being a SNAPSHOT means that it is volatile and subject to change so updates should be checked for. However it's worth pointing out that the Maven super POM configures central to have snapshots disabled, so Maven shouldn't ever check for updates for SNAPSHOTs on central unless you've overridden that in your own pom/settings.

You can configure Maven to use a mirror for the central repository, this will redirect all requests that would normally go to central to your internal repository.

In your settings.xml you would add something like this to set your internal repository as as mirror for central:

<mirrors>
  <mirror>
    <id>ibiblio.org</id>
    <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name>
    <url>http://path/to/my/repository</url>
    <mirrorOf>central</mirrorOf>
  </mirror>
</mirrors>

If you are using a repository manager like Nexus for your internal repository. You can set up a proxy repository for proxy central, so any requests that would normally go to Central are instead sent to your proxy repository (or a repository group containing the proxy), and subsequent requests are cached in the internal repository manager. You can even set the proxy cache timeout to -1, so it will never request for contents from central that are already on the proxy repository.

A more basic solution if you are only working with local repositories is to set the updatePolicy for the central repository to "never", this means Maven will only ever check for artifacts that aren't already in the local repository. This can then be overridden at the command line when needed by using the -U switch to force Maven to check for updates.

You would configure the repository (in your pom or a profile in the settings.xml) as follows:

<repository>
  <id>central</id>
  <url>http://repo1.maven.org/maven2</url>
  <updatePolicy>never</updatePolicy>
</repository>

Up to 100x faster method for thousands of remote tags

After reading through these answers while needing to delete over 11,000 tags, I learned these methods relying or xargs take far too long, unless you have hours to burn.

Struggling, I found two much faster ways. For both, start with git tag or git ls-remote --tags to make a list of tags you want to delete on the remote. In the examples below you can omit or replace sorting_proccessing_etc with any greping, sorting, tailing or heading you want (e.g. grep -P "my_regex" | sort | head -n -200 etc) :

This first method is by far the fastest, maybe 20 to 100 times faster than using xargs, and works with a least several thousand tags at a time.

git push origin $(< git tag | sorting_processing_etc \
| sed -e 's/^/:/' | paste -sd " ") #note exclude "<" for zsh

How does this work? The normal, line-separated list of tags is converted to a single line of space-separated tags, each prepended with : so . . .

tag1   becomes
tag2   ======>  :tag1 :tag2 :tag3
tag3

Using git push with this format tag pushes nothing into each remote ref, erasing it (the normal format for pushing this way is local_ref_path:remote_ref_path).

Method two is broken out as a separate answer elsewhere on this same page

After both of these methods, you'll probably want to delete your local tags too. This is much faster so we can go back to using xargs and git tag -d, which is sufficient.

git tag | sorting_processing_etc | xargs -L 1 git tag -d

OR similar to the remote delete:

git tag -d $(< git tag | sorting_processing_etc | paste -sd " ")

I think it is important to mention, now that this question is over 1 year old, that Socket.IO has since come out and seems to be the primary way to work with sockets in the browser now; it is also compatible with Node.js as far as I know.

You can also use vector::insert.

std::vector<int> v;
int a[5] = {2, 5, 8, 11, 14};

v.insert(v.end(), a, a+5);

Edit:

Of course, in real-world programming you should use:

v.insert(v.end(), a, a+(sizeof(a)/sizeof(a[0])));  // C++03
v.insert(v.end(), std::begin(a), std::end(a));     // C++11

UPDATED
Some time on, I see a comment that brings me back to my old answer, and I think I'd do it differently now. These days I'd write:

private static IEnumerable<T> GetEnumValues<T>()
{
    // Can't use type constraints on value types, so have to do check like this
    if (typeof(T).BaseType != typeof(Enum))
    {
        throw new ArgumentException("T must be of type System.Enum");
    }

    return Enum.GetValues(typeof(T)).Cast<T>();
}

Answering the question in your title, you can query sys.tables or sys.objects where type = 'U' to check for the existence of a table. You can also use OBJECT_ID('table_name', 'U'). If it returns a non-null value then the table exists:

IF (OBJECT_ID('dbo.My_Table', 'U') IS NULL)
BEGIN
    CREATE TABLE dbo.My_Table (...)
END

You can do the same for databases with DB_ID():

IF (DB_ID('My_Database') IS NULL)
BEGIN
    CREATE DATABASE My_Database
END

If you want to create the database and then start using it, that needs to be done in separate batches. I don't know the specifics of your case, but there shouldn't be many cases where this isn't possible. In a SQL script you can use GO statements. In an application it's easy enough to send across a new command after the database is created.

The only place that you might have an issue is if you were trying to do this in a stored procedure and creating databases on the fly like that is usually a bad idea.

If you really need to do this in one batch, you can get around the issue by using EXEC to get around the parsing error of the database not existing:

CREATE DATABASE Test_DB2

IF (OBJECT_ID('Test_DB2.dbo.My_Table', 'U') IS NULL)
BEGIN
    EXEC('CREATE TABLE Test_DB2.dbo.My_Table (my_id INT)')
END

EDIT: As others have suggested, the INFORMATION_SCHEMA.TABLES system view is probably preferable since it is supposedly a standard going forward and possibly between RDBMSs.

Service layer is best place to add @Transactional annotations as most of the business logic present here, it contain detail level use-case behaviour.

Suppose we add it to DAO and from service we are calling 2 DAO classes , one failed and other success , in this case if @Transactional not on service one DB will commit and other will rollback.

Hence my recommendation is use this annotation wisely and use at Service layer only.

Github project- java-algos

I encountered the same problem, probably when I uninstalled it and tried to install it again. This happens because of the database file containing login details is still stored in the pc, and the new password will not match the older one. So you can solve this by just uninstalling mysql, and then removing the left over folder from the C: drive (or wherever you must have installed).

Array.prototype.sort_by = function(key_func, reverse=false){
    return this.sort( (a, b) => ( key_func(b) - key_func(a) ) * (reverse ? 1 : -1) ) 
}

Then for example if we have

var arr = [ {id: 0, balls: {red: 8,  blue: 10}},
            {id: 2, balls: {red: 6 , blue: 11}},
            {id: 1, balls: {red: 4 , blue: 15}} ]

arr.sort_by(el => el.id, reverse=true)
/* would result in
[ { id: 2, balls: {red: 6 , blue: 11 }},
  { id: 1, balls: {red: 4 , blue: 15 }},
  { id: 0, balls: {red: 8 , blue: 10 }} ]
*/

or

arr.sort_by(el => el.balls.red + el.balls.blue)
/* would result in
[ { id: 2, balls: {red: 6 , blue: 11 }},    // red + blue= 17
  { id: 0, balls: {red: 8 , blue: 10 }},    // red + blue= 18
  { id: 1, balls: {red: 4 , blue: 15 }} ]   // red + blue= 19

Adding export PATH="$PATH:~/.composer/vendor/bin" to ~/.bashrc works in your case because you only need it when you run the terminal.
For the sake of completeness, appending it to PATH in /etc/environment (sudo gedit /etc/environment and adding ~/.composer/vendor/bin in PATH) will also work even if it is called by other programs because it is system-wide environment variable.

I would use
\b[A-Za-z]*Id\b
The \b matches the beginning and end of a word i.e. space, tab or newline, or the beginning or end of a string.

The [A-Za-z] will match any letter, and the * means that 0+ get matched. Finally there is the Id.

Note that this will match words that have capital letters in the middle such as 'teStId'.

USE COUNT_STAR

LOGS= LOAD 'log';
LOGS_GROUP= GROUP LOGS ALL;
LOG_COUNT = FOREACH LOGS_GROUP GENERATE COUNT_STAR(LOGS);

Simple Example:

    print("First line of code executed")
    // do stuff here to determine what you want to "send back".
    // we are just sending the Boolean value that was sent in "back"
    completion(arg)

How to use it:

method(arg: true, completion: { (success) -> Void in
    print("Second line of code executed")
    if success { // this will be equal to whatever value is set in this method call
          print("true")

Use -qscale:v to control quality

Use -qscale:v (or the alias -q:v) as an output option.

• Normal range for JPEG is 2-31 with 31 being the worst quality.
• The scale is linear with double the qscale being roughly half the bitrate.
• Recommend trying values of 2-5.
• You can use a value of 1 but you must add the -qmin 1 output option (because the default is -qmin 2).

To output a series of images:

ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg

See the image muxer documentation for more options involving image outputs.

To output a single image at ~60 seconds duration:

ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg

Also see

• FFmpeg FAQ: How do I encode movie to single pictures?
• FFmpeg Wiki: Create a thumbnail image every X seconds of the video

Another way with lodash 4.17.2

_.chain(params)
    .keyBy('name')
    .mapValues('input')
    .value();

or

_.mapValues(_.keyBy(params, 'name'), 'input')

or with _.reduce

_.reduce(
    params,
    (acc, { name, input }) => ({ ...acc, [name]: input }),
    {}
)

Try this:

^[0-9]{4,6}$

{4,6} = between 4 and 6 characters, inclusive.

In MSDN, Assembly.GetExecutingAssembly Method, is remark about method "getexecutingassembly", that for performance reasons, you should call this method only when you do not know at design time what assembly is currently executing.

The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly property of a type found in the assembly.

The following example illustrates:

using System;
using System.Reflection;

public class Example
{
    public static void Main()
    {
        Console.WriteLine("The version of the currently executing assembly is: {0}",
                          typeof(Example).Assembly.GetName().Version);
    }
}

/* This example produces output similar to the following:
   The version of the currently executing assembly is: 1.1.0.0

Of course this is very similar to the answer with helper class "public static class CoreAssembly", but, if you know at least one type of executing assembly, it isn't mandatory to create a helper class, and it saves your time.
