If I understand your problem well you want the following things:

1. Have your media files stored in one single git repository, which is used by many projects
2. If you modify a media file in any of the projects in your local machine, it should immediately appear in every other project (so you don't want to commit+push+pull all the time)

Unfortunately there is no ultimate solution for what you want, but there are some things by which you can make your life easier.

First you should decide one important thing: do you want to store for every version in your project repository a reference to the version of the media files? So for example if you have a project called example.com, do you need know which style.css it used 2 weeks ago, or the latest is always (or mostly) the best?

If you don't need to know that, the solution is easy:

1. create a repository for the media files and one for each project
2. create a symbolic link in your projects which point to the locally cloned media repository. You can either create a relative symbolic link (e.g. ../media) and assume that everybody will checkout the project so that the media directory is in the same place, or write the name of the symbolic link into .gitignore, and everybody can decide where he/she puts the media files.

In most of the cases, however, you want to know this versioning information. In this case you have two choices:

1. Store every project in one big repository. The advantage of this solution is that you will have only 1 copy of the media repository. The big disadvantage is that it is much harder to switch between project versions (if you checkout to a different version you will always modify ALL projects)

2. Use submodules (as explained in answer 1). This way you will store the media files in one repository, and the projects will contain only a reference to a specific media repo version. But this way you will normally have many local copies of the media repository, and you cannot easily modify a media file in all projects.

If I were you I would probably choose the first or third solution (symbolic links or submodules). If you choose to use submodules you can still do a lot of things to make your life easier:

1. Before committing you can rename the submodule directory and put a symlink to a common media directory. When you're ready to commit, you can remove the symlink and remove the submodule back, and then commit.

2. You can add one of your copy of the media repository as a remote repository to all of your projects.

You can add local directories as a remote this way:

cd /my/project2/media
git remote add project1 /my/project1/media

If you modify a file in /my/project1/media, you can commit it and pull it from /my/project2/media without pushing it to a remote server:

cd /my/project1/media
git commit -a -m "message"
cd /my/project2/media
git pull project1 master

You are free to remove these commits later (with git reset) because you haven't shared them with other users.

Disable horizontal scrollbar completely by adding this code.

body{
  overflow-x: hidden;
  overflow-y: scroll;
}

children() only looks at the immediate children of the node, while find() traverses the entire DOM below the node, so children() should be faster given equivalent implementations. However, find() uses native browser methods, while children() uses JavaScript interpreted in the browser. In my experiments there isn't much performance difference in typical cases.

Which to use depends on whether you only want to consider the immediate descendants or all nodes below this one in the DOM, i.e., choose the appropriate method based on the results you desire, not the speed of the method. If performance is truly an issue, then experiment to find the best solution and use that (or see some of the benchmarks in the other answers here).

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

Simple

The array of integers is quite simple to pass. However this solution works for more complex data as well. In your model:

public int[] Numbers => new int[5];

In your view:

numbers = @(new HtmlString(JsonSerializer.Serialize(Model.Numbers)))

Optional

A tip for passing strings. You may want JSON encoder to not escape some symbols in your strings. In this example I want raw unescaped cyrillic letters. In your view:

strings = @(
new HtmlString(
    JsonSerializer.Serialize(Model.Strings, new JsonSerializerOptions
    {
        Encoder = JavaScriptEncoder.Create(
            UnicodeRanges.BasicLatin,
            UnicodeRanges.Cyrillic)
    })))

 <style name="WhiteTextWithShadow" parent="@android:style/TextAppearance">
    <item name="android:shadowDx">1</item>
    <item name="android:shadowDy">1</item>
    <item name="android:shadowRadius">1</item>
    <item name="android:shadowColor">@android:color/black</item>
    <item name="android:textColor">@android:color/white</item>
</style>

then use as

 <TextView
            android:id="@+id/text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="15sp"
            tools:text="Today, May 21"
            style="@style/WhiteTextWithShadow"/>

I would avoid using a relative path. Remember that docker is a daemon/client relationship.

When you are executing the compose, it's essentially just breaking down into various docker client commands, which are then passed to the daemon. That ./database is then relative to the daemon, not the client.

Now, the docker dev team has some back and forth on this issue, but the bottom line is it can have some unexpected results.

In short, don't use a relative path, use an absolute path.

A binary search tree is a special kind of binary tree which exhibits the following property: for any node n, every descendant node's value in the left subtree of n is less than the value of n, and every descendant node's value in the right subtree is greater than the value of n.

You can see some reports in SSMS:

Right-click the instance name / reports / standard / top sessions

You can see top CPU consuming sessions. This may shed some light on what SQL processes are using resources. There are a few other CPU related reports if you look around. I was going to point to some more DMVs but if you've looked into that already I'll skip it.

You can use sp_BlitzCache to find the top CPU consuming queries. You can also sort by IO and other things as well. This is using DMV info which accumulates between restarts.

This article looks promising.

Some stackoverflow goodness from Mr. Ozar.

edit: A little more advice... A query running for 'only' 5 seconds can be a problem. It could be using all your cores and really running 8 cores times 5 seconds - 40 seconds of 'virtual' time. I like to use some DMVs to see how many executions have happened for that code to see what that 5 seconds adds up to.

This came across while working on a project on linux platform.

exec('wget http://<url to the php script>)

This runs as if you run the script from browser.

Hope this helps!!

Warning: Never ever refer to w3schools for learning purposes. They have so many mistakes in their tutorials.

According to the mysqli_query documentation, the first parameter must be a connection string:

$link = mysqli_connect("localhost","root","","web_table");

mysqli_query($link,"INSERT INTO web_formitem (`ID`, `formID`, `caption`, `key`, `sortorder`, `type`, `enabled`, `mandatory`, `data`)
VALUES (105, 7, 'Tip izdelka (6)', 'producttype_6', 42, 5, 1, 0, 0)") 
or die(mysqli_error($link));

Note: Add backticks ` for column names in your insert query as some of your column names are reserved words.

Since we have a virtual address space of 2^32 and each page size is 2^12, we can store (2^32/2^12) = 2^20 pages. Since each entry into this page table has an address of size 4 bytes, then we have 2^20*4 = 4MB. So the page table takes up 4MB in memory.

I had exactly the same error message. In my case, making an entry in my /etc/hosts file (on the server hosting the service) for the target server referenced in the WSDL fixed it.

Kind of a strangely worded error message..

You have everything right, but the problem is with getLine1Number() function.

getLine1Number()- this method returns the phone number string for line 1, i.e the MSISDN for a GSM phone. Return null if it is unavailable.

this method works only for few cell phone but not all phones.

So, if you need to perform operations according to the sim(other than calling), then you should use getSimSerialNumber(). It is always unique, valid and it always exists.

This is what I use:

var result = [];
for (var l in someObject){
  if (someObject.hasOwnProperty(l){
    result.push(l+': '+someObject[l]);
  }
}
alert(result.join('\n'));

If you want to show nested objects too, you could use something recursive:

function alertObject(obj){
 var result = [];
 function traverse(obj){
 for (var l in obj){
   if (obj.hasOwnProperty(l)){
     if (obj[l] instanceof Object){
       result.push(l+'=>[object]');
       traverse(obj[l]);
     } else {
       result.push(l+': '+obj[l]);
     }
   }
  }
 }
 traverse(obj);
 return result;
}

You can either use

break;

or

foreach() if ($tmp++ < 2) {
}

(the second solution is even worse)

Use this regular expression to match square brackets or single quotes:

/[\[\]']+/g

Replace with the empty string.

console.log("['abc','xyz']".replace(/[\[\]']+/g,''));

Use a BOM to solve version issues.

you may find that a third-party library, or another Spring project, pulls in a transitive dependency to an older release. If you forget to explicitly declare a direct dependency yourself, all sorts of unexpected issues can arise.

To overcome such problems Maven supports the concept of a "bill of materials" (BOM) dependency.

https://docs.spring.io/spring/docs/4.3.18.RELEASE/spring-framework-reference/html/overview.html#overview-maven-bom

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-framework-bom</artifactId>
  <version>3.2.12.RELEASE</version>
  <type>pom</type>
</dependency>

Try:

Key = i.ToString("000000");

Personally, though, I'd see if you can't sort on the integer directly, rather than the string representation.

This generates a consistent hash based on any number of params passed in:

/**
 * Generates a hash from params passed in
 * @returns {string} hash based on params
 */
function fastHashParams() {
    var args = Array.prototype.slice.call(arguments).join('|');
    var hash = 0;
    if (args.length == 0) {
        return hash;
    }
    for (var i = 0; i < args.length; i++) {
        var char = args.charCodeAt(i);
        hash = ((hash << 5) - hash) + char;
        hash = hash & hash; // Convert to 32bit integer
    }
    return String(hash);
}

fastHashParams('hello world') outputs "990433808"

fastHashParams('this',1,'has','lots','of','params',true) outputs "1465480334"

Currently you are clearing the name array, you need to call the array then the index you want to unset within the array:

$ar[0]==2
$ar[1]==7
$ar[2]==9

unset ($ar[2])

Two ways of unsetting values within an array:

<?php
# remove by key:
function array_remove_key ()
{
  $args  = func_get_args();
  return array_diff_key($args[0],array_flip(array_slice($args,1)));
}
# remove by value:
function array_remove_value ()
{
  $args = func_get_args();
  return array_diff($args[0],array_slice($args,1));
}

$fruit_inventory = array(
  'apples' => 52,
  'bananas' => 78,
  'peaches' => 'out of season',
  'pears' => 'out of season',
  'oranges' => 'no longer sold',
  'carrots' => 15,
  'beets' => 15,
);

echo "<pre>Original Array:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';

# For example, beets and carrots are not fruits...
$fruit_inventory = array_remove_key($fruit_inventory,
                                    "beets",
                                    "carrots");
echo "<pre>Array after key removal:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';

# Let's also remove 'out of season' and 'no longer sold' fruit...
$fruit_inventory = array_remove_value($fruit_inventory,
                                      "out of season",
                                      "no longer sold");
echo "<pre>Array after value removal:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';
?> 

So, unset has no effect to internal array counter!!!

The following one-liner has worked for me.

window.onbeforeunload = s => modified ? "" : null;

Just set modified to true or false depending on the state of your application.

I tried the below and it worked well,

and follow the below steps in excel

There is currently no way to do this out of the box, but there is a User Voice suggestion for adding it: http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2037649-implement-indexed-full-text-search-of-work-items

While I doubt it is as simple as flipping a switch, if everyone that has viewed this question voted for it, MS would probably implement something.

Update: Just read Brian Harry's blog, which shows this request as being on their radar, and the Online version of Visual Studio has limited support for searching where git is used as the vcs: http://blogs.msdn.com/b/visualstudioalm/archive/2015/02/13/announcing-limited-preview-for-visual-studio-online-code-search.aspx. From this I think it's fair to say it is just a matter of time...

Update 2: There is now a Microsoft provided extension,Code Search which enables searching in code as well as in work items.

I believe I found quite a nifty way to deal with this issue, taking up only three lines of code (barring line wraps). The following is lifted directly from a function I am writing, and it seems to work as desired:

defaults = {50/6,3,true,false,[375,20,50,0]}; %set all defaults
defaults(1:nargin-numberForcedParameters) = varargin; %overload with function input
[sigma,shifts,applyDifference,loop,weights] = ...
     defaults{:}; %unfold the cell struct

Just thought I'd share it.

I implemented something similar with Horizontal Variable ListView The only drawback is, it works only with Android 2.3 and later.

Using this library is as simple as implementing a ListView with a corresponding Adapter. The library also provides an example

In addition to Boaz's answer ....

@UniqueConstraint allows you to name the constraint, while @Column(unique = true) generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).

Sometimes it can be helpful to know what table a constraint is associated with. E.g.:

@Table(
   name = "product_serial_group_mask", 
   uniqueConstraints = {
      @UniqueConstraint(
          columnNames = {"mask", "group"},
          name="uk_product_serial_group_mask"
      )
   }
)

you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment

<div style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: gray;height:30px;">
   <div style="float:left;line-height:30px;">Contact Details</div>

    <button type="button" class="edit_button" style="float: right;">My Button</button>

</div>

also js fiddle here =) http://jsfiddle.net/xQgSm/

Use position: fixed, and anchor it to the top and right sides of the page:

#fixed-div {
    position: fixed;
    top: 1em;
    right: 1em;
}

IE6 does not support position: fixed, however. If you need this functionality in IE6, this purely-CSS solution seems to do the trick. You'll need a wrapper <div> to contain some of the styles for it to work, as seen in the stylesheet.

When starting the JVM, two parameters can be adjusted to suit your memory needs :

As a python3 user,

The difference between load and loads methods is important especially when you read json data from file.

As stated in the docs:

json.load:

Deserialize fp (a .read()-supporting text file or binary file containing a JSON document) to a Python object using this conversion table.

json.loads:

json.loads: Deserialize s (a str, bytes or bytearray instance containing a JSON document) to a Python object using this conversion table.

json.load method can directly read opened json document since it is able to read binary file.

with open('./recipes.json') as data:
  all_recipes = json.load(data)

As a result, your json data available as in a format specified according to this conversion table:

--create a user that you want to use the database as:

create role neil;

--create the user for the web server to connect as:

create role webgui noinherit login password 's3cr3t';

--let webgui set role to neil:

grant neil to webgui; --this looks backwards but is correct.

webgui is now in the neil group, so webgui can call set role neil . However, webgui did not inherit neil's permissions.

Later, login as webgui:

psql -d some_database -U webgui
(enter s3cr3t as password)

set role neil;

webgui does not need superuser permission for this.

You want to set role at the beginning of a database session and reset it at the end of the session. In a web app, this corresponds to getting a connection from your database connection pool and releasing it, respectively. Here's an example using Tomcat's connection pool and Spring Security:

public class SetRoleJdbcInterceptor extends JdbcInterceptor {

    @Override
    public void reset(ConnectionPool connectionPool, PooledConnection pooledConnection) {

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

        if(authentication != null) {
            try {

                /* 
                  use OWASP's ESAPI to encode the username to avoid SQL Injection. Can't use parameters with SET ROLE. Need to write PG codec.

                  Or use a whitelist-map approach
                */
                String username = ESAPI.encoder().encodeForSQL(MY_CODEC, authentication.getName());

                Statement statement = pooledConnection.getConnection().createStatement();
                statement.execute("set role \"" + username + "\"");
                statement.close();
            } catch(SQLException exp){
                throw new RuntimeException(exp);
            }
        }
    }

    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {

        if("close".equals(method.getName())){
            Statement statement = ((Connection)proxy).createStatement();
            statement.execute("reset role");
            statement.close();
        }

        return super.invoke(proxy, method, args);
    }
}

You may want to look into Maven release plugin's release:update-versions goal. It will update the parent's version as well as all the modules under it.

mvn versions:set -DnewVersion=1.2.3-SNAPSHOT

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

It is incredible that there are so many answers but none answers the question:

"When I was asking this question, I asked for a way of opening a UTF-8 CSV file in Excel without any problems for a user,..."

The answer marked as the accepted answer with 200+ up-votes is useless for me because I don't want to give my users a manual how to configure Excel. Apart from that: this manual will apply to one Excel version but other Excel versions have different menus and configuration dialogs. You would need a manual for each Excel version.

So the question is how to make Excel show UTF8 data with a simple double click?

Well at least in Excel 2007 this is not possible if you use CSV files because the UTF8 BOM is ignored and you will see only garbage. This is already part of the question of Lyubomyr Shaydariv:

"I also tried specifying UTF-8 BOM EF BB BF, but Excel ignores that."

I make the same experience: Writing russian or greek data into a UTF8 CSV file with BOM results in garbage in Excel:

Content of UTF8 CSV file:

Colum1;Column2
Val1;Val2
?????????;T??????

Result in Excel 2007:

A solution is to not use CSV at all. This format is implemented so stupidly by Microsoft that it depends on the region settings in control panel if comma or semicolon is used as separator. So the same CSV file may open correctly on one computer but on anther computer not. "CSV" means "Comma Separated Values" but for example on a german Windows by default semicolon must be used as separator while comma does not work. (Here it should be named SSV = Semicolon Separated Values) CSV files cannot be interchanged between different language versions of Windows. This is an additional problem to the UTF-8 problem.

Excel exists since decades. It is a shame that Microsoft was not able to implement such a basic thing as CSV import in all these years.

However, if you put the same values into a HTML file and save that file as UTF8 file with BOM with the file extension XLS you will get the correct result.

Content of UTF8 XLS file:

<table>
<tr><td>Colum1</td><td>Column2</td></tr>
<tr><td>Val1</td><td>Val2</td></tr>
<tr><td>?????????</td><td>T??????</td></tr>
</table>

Result in Excel 2007:

You can even use colors in HTML which Excel will show correctly.

<style>
.Head { background-color:gray; color:white; }
.Red  { color:red; }
</style>
<table border=1>
<tr><td class=Head>Colum1</td><td class=Head>Column2</td></tr>
<tr><td>Val1</td><td>Val2</td></tr>
<tr><td class=Red>?????????</td><td class=Red>T??????</td></tr>
</table>

Result in Excel 2007:

In this case only the table itself has a black border and lines. If you want ALL cells to display gridlines this is also possible in HTML:

<html xmlns:x="urn:schemas-microsoft-com:office:excel">
    <head>
        <meta http-equiv="content-type" content="text/plain; charset=UTF-8"/>
        <xml>
            <x:ExcelWorkbook>
                <x:ExcelWorksheets>
                    <x:ExcelWorksheet>
                        <x:Name>MySuperSheet</x:Name>
                        <x:WorksheetOptions>
                            <x:DisplayGridlines/>
                        </x:WorksheetOptions>
                    </x:ExcelWorksheet>
                </x:ExcelWorksheets>
            </x:ExcelWorkbook>
        </xml>
    </head>
    <body>
        <table>
            <tr><td>Colum1</td><td>Column2</td></tr>
            <tr><td>Val1</td><td>Val2</td></tr>
            <tr><td>?????????</td><td>T??????</td></tr>
        </table>
    </body>
</html>

This code even allows to specify the name of the worksheet (here "MySuperSheet")

Result in Excel 2007:

"Unexpected end of file" implies that the remote server accepted and closed the connection without sending a response. It's possible that the remote system is too busy to handle the request, or that there's a network bug that randomly drops connections.

It's also possible there is a bug in the server: something in the request causes an internal error, and the server simply closes the connection instead of sending a HTTP error response like it should. Several people suggest this is caused by missing headers or invalid header values in the request.

With the information available it's impossible to say what's going wrong. If you have access to the servers in question you can use packet sniffing tools to find what exactly is sent and received, and look at logs to of the server process to see if there are any error messages.

CSS selector space actually allows for conditional id style:

h1#my-id {color:red}
p#my-id {color:blue}

will render as expected. Why would you do this? Sometimes IDs are generated dynamically, etc. A further use has been to render titles differently based on a high-level ID assignment:

body#list-page #title {font-size:56px}
body#detail-page #title {font-size:24px}

Personally, I prefer longer classname selectors:

body#list-page .title-block > h1 {font-size:56px}

as I find using nested IDs to differentiate treatment to be a bit perverse. Just know that as developers in the Sass/SCSS world get their hands on this stuff, nested IDs are becoming the norm.

Finally, when it comes to selector performance and precedence, ID tends to win out. This is a whole other subject.

I had the same problem. I solved it by switching to <a> and add onclick="return false;" (so that clicking on it won't add a new entry to browser history).

To store the array values in cookie, first you need to convert them to string, so here is some options.

Storing cookies as JSON

Storing code

setcookie('your_cookie_name', json_encode($info), time()+3600);

Reading code

$data = json_decode($_COOKIE['your_cookie_name'], true);

JSON can be good choose also if you need read cookie in front end with JavaScript.

Actually you can use any encrypt_array_to_string/decrypt_array_from_string methods group that will convert array to string and convert string back to same array. For example you can also use explode/implode for array of integers.

Warning: Do not use serialize/unserialize

From PHP.net

Do not pass untrusted user input to unserialize(). - Anything that coming by HTTP including cookies is untrusted!

As an alternative solution, you can do it also without converting array to string.

setcookie('my_array[0]', 'value1' , time()+3600);
setcookie('my_array[1]', 'value2' , time()+3600);
setcookie('my_array[2]', 'value3' , time()+3600);

And after if you will print $_COOKIE variable, you will see the following

echo '<pre>';
print_r( $_COOKIE );
die();

Array
(   
    [my_array] => Array
        (
            [0] => value1
            [1] => value2
            [2] => value3
        )

)

This is documented PHP feature.

From PHP.net

Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system.

This code worked for me:

ListBox1.Items.RemoveAt(ListBox1.SelectedIndex)

You could use something like the following

scp -r username_Linuxmachine@LinuxMachineAddress:Path/To/File Path/To/Local/System/Directory

This will copy the File to the specified local directory on the system you are currently working on.

The -r flag tells scp to recursively copy if the remote path is indeed a directory.

Variable scope in Ruby is controlled by sigils to some degree. Variables starting with $ are global, variables with @ are instance variables, @@ means class variables, and names starting with a capital letter are constants. All other variables are locals. When you open a class or method, that's a new scope, and locals available in the previous scope aren't available.

I generally prefer to avoid creating global variables. There are two techniques that generally achieve the same purpose that I consider cleaner:

1. Create a constant in a module. So in this case, you would put all the classes that need the offset in the module Foo and create a constant Offset, so then all the classes could access Foo::Offset.

2. Define a method to access the value. You can define the method globally, but again, I think it's better to encapsulate it in a module or class. This way the data is available where you need it and you can even alter it if you need to, but the structure of your program and the ownership of the data will be clearer. This is more in line with OO design principles.

Unlike other managed programming language, "static class" has NO meaning in C++. You can make use of static member function.

autobox::Core provides, among many more things, a handy for method:

use autobox::Core;

['a'..'z']->for( sub{
    my ($index, $value) = @_;
    say "$index => $value";
});

Alternatively, have a look at an iterator module, for example: Array::Iterator

use Array::Iterator;

my $iter = Array::Iterator->new( ['a'..'z'] );
while ($iter->hasNext) {
    $iter->getNext;
    say $iter->currentIndex . ' => ' . $iter->current;
}

Also see:

• each to their own (autobox)
• perl5i

Hm, combining LEFT and RIGHT JOIN with UNION could do this:

SELECT  p.LastName, p.FirstName, o.OrderNo
FROM    persons AS p
LEFT JOIN
        orders AS o
ON      p.P_Id = Orders.P_Id
UNION ALL
SELECT  p.LastName, p.FirstName, o.OrderNo
FROM    persons AS p 
RIGHT JOIN
        orders AS o
ON      p.P_Id = Orders.P_Id
WHERE   p.P_Id IS NULL

you need the set key and value in foreach loop for that:

foreach($item AS $key -> $value) {
echo $value;
}

this should do the trick :)

Unfortunately, there is a character limit so this will be in many parts. First thing to note is that return and print are statements, not functions, but that is just semantics.

I’ll start with a basic explanation. print just shows the human user a string representing what is going on inside the computer. The computer cannot make use of that printing. return is how a function gives back a value. This value is often unseen by the human user, but it can be used by the computer in further functions.

On a more expansive note, print will not in any way affect a function. It is simply there for the human user’s benefit. It is very useful for understanding how a program works and can be used in debugging to check various values in a program without interrupting the program.

return is the main way that a function returns a value. All functions will return a value, and if there is no return statement (or yield but don’t worry about that yet), it will return None. The value that is returned by a function can then be further used as an argument passed to another function, stored as a variable, or just printed for the benefit of the human user. Consider these two programs:

def function_that_prints():
    print "I printed"

def function_that_returns():
    return "I returned"

f1 = function_that_prints()
f2 = function_that_returns()

print "Now let us see what the values of f1 and f2 are"

print f1 --->None

print f2---->"I returned"

When function_that_prints ran, it automatically printed to the console "I printed". However, the value stored in f1 is None because that function had no return statement.

When function_that_returns ran, it did not print anything to the console. However, it did return a value, and that value was stored in f2. When we printed f2 at the end of the code, we saw "I returned"

In the terminal, use "mongo" command to switch the terminal into the MongoDB shell:

$ mongo
MongoDB shell version: 2.6.10
connecting to: admin
>

Once you get > symbol in the terminal, you have entered into the MongoDB shell.

Floats don't affect the flow. What I tend to do is add a

<p class="extro" style="clear: both">possibly some content</p>

at the end of the 'wrapping div' (in this case content). I can justify this on a semantic basis by saying that such a paragraph might be needed. Another approach is to use a clearfix CSS:

#content:after {
  content: ".";
  display: block;
  height: 0;
  clear: both;
  visibility: hidden;
}

#content {
  display: inline-block;
}
/*  \*/
* html #content {
  height: 1%;
}

#content {
  display: block;
}
/*  */

The trickery with the comments is for cross-browser compatibility.

To help debug, and make your code better, do this:

private void processLine(String[] strings) {
    Integer[] intarray=new Integer[strings.length];
    int i=0;
    for(String str:strings){
        try {
            intarray[i]=Integer.parseInt(str);
            i++;
        } catch (NumberFormatException e) {
            throw new IllegalArgumentException("Not a number: " + str + " at index " + i, e);
        }
    }
}

Also, from a code neatness point, you could reduce the lines by doing this:

for (String str : strings)
    intarray[i++] = Integer.parseInt(str);

I made an extension to disable it on all sites. In doing so I used three techniques: pure CSS, pure JS and hybrid.

The CSS version is similar to the above solutions. The JS one goes a bit like this:

var scroll = function(e) {
    // compute state
    if (stopScrollX || stopScrollY) {
        e.preventDefault();              // this one is the key
        e.stopPropagation();
        window.scroll(scrollToX, scrollToY);
    }
}

document.addEventListener('mousewheel', scroll, false);

The CSS one works when one is using position: fixed elements and let the browser do the scrolling. The JS one is needed when some other JS depends on window (e.g events), which would get blocked by the previous CSS (since it makes the body scroll instead of the window), and works by stopping event propagation at the edges, but needs to synthesize the scrolling of the non-edge component; the downside is that it prevents some types of scrolling to happen (those do work with the CSS one). The hybrid one tries to take a mixed approach by selectively disabling directional overflow (CSS) when scrolling reaches an edge (JS), and in theory could work in both cases, but doesn't quite currently as it has some leeway at the limit.

So depending on the implementations of one's website, one needs to either take one approach or the other.

I've used the "slugify" method from underscore.string and it worked like a charm:

https://github.com/epeli/underscore.string#slugifystring--string

The cool thing is that you can really just import this method, don't need to import the entire library.

Lodash is also the same First write a script as follows:

<script type="text/template" id="genTable">
<table cellspacing='0' cellpadding='0' border='1'>
        <tr>
            <% for(var prop in users[0]){%>
            <th><%= prop %> </th>
            <% }%>
        </tr>
        <%_.forEach(users, function(user) { %>
            <tr>
                 <% for(var prop in user){%>
                    <td><%= user[prop] %> </td>
                <% }%>

            </tr>
        <%})%>
</table>

Now write some simple JS as follows:

var arrOfObjects = [];
for (var s = 0; s < 10; s++) {
    var simpleObject = {};
    simpleObject.Name = "Name_" + s;
    simpleObject.Address = "Address_" + s;
    arrOfObjects[s] = simpleObject;
}
var theObject = { 'users': arrOfObjects }
var compiled = _.template($("#genTable").text());
var sigma = compiled({ 'users': myArr });

$(sigma).appendTo("#popup");

Where popoup is a div where you want to generate the table

See this article for tips on how to help performance issues. This includes both performance issues related to starting up, under the "cold start" section. Most of this will matter no matter what type of server you are using, locally or in production.

https://blogs.msdn.microsoft.com/b/mcsuksoldev/2011/01/19/common-performance-issues-on-asp-net-web-sites/

If the application deserializes anything from XML (and that includes web services…) make sure SGEN is run against all binaries involved in deseriaization and place the resulting DLLs in the Global Assembly Cache (GAC). This precompiles all the serialization objects used by the assemblies SGEN was run against and caches them in the resulting DLL. This can give huge time savings on the first deserialization (loading) of config files from disk and initial calls to web services. http://msdn.microsoft.com/en-us/library/bk3w6240(VS.80).aspx

If any IIS servers do not have outgoing access to the internet, turn off Certificate Revocation List (CRL) checking for Authenticode binaries by adding generatePublisherEvidence=”false” into machine.config. Otherwise every worker processes can hang for over 20 seconds during start-up while it times out trying to connect to the internet to obtain a CRL list. http://blogs.msdn.com/amolravande/archive/2008/07/20/startup-performance-disable-the-generatepublisherevidence-property.aspx

http://msdn.microsoft.com/en-us/library/bb629393.aspx

Consider using NGEN on all assemblies. However without careful use this doesn’t give much of a performance gain. This is because the base load addresses of all the binaries that are loaded by each process must be carefully set at build time to not overlap. If the binaries have to be rebased when they are loaded because of address clashes, almost all the performance gains of using NGEN will be lost. http://msdn.microsoft.com/en-us/magazine/cc163610.aspx

Annotations do provide meta data about the code to the Compiler and the annotation @Override is used in case of inheritance when we are overriding any method of base class. It just tells the compiler that you are overriding method. It can avoide some kinds common mistakes we can do like not following the proper signature of the method or mispelling in name of the method etc. So its a good practice to use @Override annotation.

If you are sure id.substring(indexPos) is a number, you can do it like so:

var number = Number(id.substring(indexPos)) + 1;

Otherwise I suggest checking if the Number function evaluates correctly.

Difference between forEach() & map()

forEach() just loop through the elements. It's throws away return values and always returns undefined.The result of this method does not give us an output .

map() loop through the elements allocates memory and stores return values by iterating main array

Example:

   var numbers = [2,3,5,7];

   var forEachNum = numbers.forEach(function(number){
      return number
   })
   console.log(forEachNum)
   //output undefined

   var mapNum = numbers.map(function(number){
      return number
   })
   console.log(mapNum)
   //output [2,3,5,7]

map() is faster than forEach()

From the documentation for scatter:

Optional kwargs control the Collection properties; in particular:

    edgecolors:
        The string ‘none’ to plot faces with no outlines
    facecolors:
        The string ‘none’ to plot unfilled outlines

Try the following:

import matplotlib.pyplot as plt 
import numpy as np 

x = np.random.randn(60) 
y = np.random.randn(60)

plt.scatter(x, y, s=80, facecolors='none', edgecolors='r')
plt.show()

Note: For other types of plots see this post on the use of markeredgecolor and markerfacecolor.

I was just answering a very similar question about this, and happened to find this when looking for a link to back up my claims, so lucky you :)

My other answer:
The ViewPager does not support wrap_content as it (usually) never have all its children loaded at the same time, and can therefore not get an appropriate size (the option would be to have a pager that changes size every time you have switched page).

You can however set a precise dimension (e.g. 150dp) and match_parent works as well.
You can also modify the dimensions dynamically from your code by changing the height-attribute in its LayoutParams.

For your needs you can create the ViewPager in its own xml-file, with the layout_height set to 200dp, and then in your code, rather than creating a new ViewPager from scratch, you can inflate that xml-file:

LayoutInflater inflater = context.getLayoutInflater();
inflater.inflate(R.layout.viewpagerxml, layout, true);

Take a look at HTMLSelectElement.selectedOptions.

HTML

<select name="north-america" multiple>
  <option valud="ca" selected>Canada</a>
  <option value="mx" selected>Mexico</a>
  <option value="us">USA</a>
</select>

JavaScript

var elem = document.querySelector("select");

console.log(elem.selectedOptions);
//=> HTMLCollection [<option value="ca">Canada</option>, <option value="mx">Mexico</option>]

This would also work on non-multiple <select> elements

Warning: Support for this selectedOptions seems pretty unknown at this point

temp3 = [item for item in temp1 if item not in temp2]

The only way I can get this to work is to manually instantiate the section handler type, pass the raw XML to it, and cast the resulting object.

Seems pretty inefficient, but there you go.

I wrote an extension method to encapsulate this:

public static class ConfigurationSectionExtensions
{
    public static T GetAs<T>(this ConfigurationSection section)
    {
        var sectionInformation = section.SectionInformation;

        var sectionHandlerType = Type.GetType(sectionInformation.Type);
        if (sectionHandlerType == null)
        {
            throw new InvalidOperationException(string.Format("Unable to find section handler type '{0}'.", sectionInformation.Type));
        }

        IConfigurationSectionHandler sectionHandler;
        try
        {
            sectionHandler = (IConfigurationSectionHandler)Activator.CreateInstance(sectionHandlerType);
        }
        catch (InvalidCastException ex)
        {
            throw new InvalidOperationException(string.Format("Section handler type '{0}' does not implement IConfigurationSectionHandler.", sectionInformation.Type), ex);
        }

        var rawXml = sectionInformation.GetRawXml();
        if (rawXml == null)
        {
            return default(T);
        }

        var xmlDocument = new XmlDocument();
        xmlDocument.LoadXml(rawXml);

        return (T)sectionHandler.Create(null, null, xmlDocument.DocumentElement);
    }
}

The way you would call it in your example is:

var map = new ExeConfigurationFileMap
{
    ExeConfigFilename = @"c:\\foo.config"
};
var configuration = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);
var myParamsSection = configuration.GetSection("MyParams");
var myParamsCollection = myParamsSection.GetAs<NameValueCollection>();

To avoid to add sources files .java to your package you should do

cd src/
jar cvf mylib.jar com/**/*.class

Supposed that your project structure was like

myproject/
    src/
      com/
        mycompany/
          mainClass.java
          mainClass.class

I see all answers recommend using str(object). It might fail if your object have more than ascii characters and you will see error like ordinal not in range(128). This was the case for me while I was converting list of string in language other than English

I resolved it by using unicode(object)

_httpClient = new HttpClient(handler) {Timeout = TimeSpan.FromSeconds(5)};

is what I usually do, seems to work out pretty good for me, its especially good when using proxies.

Although the above answers all work, What you originally tried to do was the correct way, however you just have the syntax backwards (switch "$size" and "$gt")..

Correct:

db.collection.find({items: {$gt: {$size: 1}}})

Incorrect:

db.collection.find({items: {$size: {$gt: 1}}})

try this:

<IfModule mod_headers.c>
     Header set Access-Control-Allow-Credentials true
     Header set Access-Control-Allow-Origin "your domain"
     Header set Access-Control-Allow-Headers "X-Requested-With"
</IfModule>

It's preferable to allow a list of know trusted host.

also just try adding double slashes like this works for me only

set dir="C:\\1. Some Folder\\Some Other Folder\\Just Because"

@echo on MKDIR %dir%

OMG after posting they removed the second \ in my post so if you open my comment and it shows three you should read them as two......

Just to follow up on this since the top answer recommends not using materializecss... in the current version of materialize you no longer need to initialize selects.

You can select the rows from the table you want to export in the MySQL Workbench SQL Editor. You will find an Export button in the resultset that will allow you to export the records to a CSV file, as shown in the following image:

Please also keep in mind that by default MySQL Workbench limits the size of the resultset to 1000 records. You can easily change that in the Preferences dialog:

Hope this helps.

For me none of the packages mentioned above did help.

I finally managed to install lxml after running:

sudo apt-get install python3.5-dev

Better to use a vbs as you indicated

1. Create a simple vbs, which is a text file with a .vbs extension (see sample code below)
2. Use the Task Scheduler to run the vbs
3. Use the vbs to open the workbook at the scheduled time and then either:
   • use the Private Sub Workbook_Open() event in the ThisWorkbook module to run code when the file is opened
   • more robustly (as macros may be disabled on open), use Application.Run in the vbs to run the macro

See this example of the later approach at Running Excel on Windows Task Scheduler

sample vbs

Dim ObjExcel, ObjWB
Set ObjExcel = CreateObject("excel.application")
'vbs opens a file specified by the path below
Set ObjWB = ObjExcel.Workbooks.Open("C:\temp\rod.xlsm")
'either use the Workbook Open event (if macros are enabled), or Application.Run

ObjWB.Close False
ObjExcel.Quit
Set ObjExcel = Nothing

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

My mistake, the resource files WERE actually copied to target/test-classes. The problem seemed to be due to spaces in my project name, e.g. Project%20Name.

I'm now loading the file as follows and it works:

org.apache.commons.io.FileUtils.toFile(myClass().getResource("resourceFile.txt")??);

Or, (taken from Java: how to get a File from an escaped URL?) this may be better (no dependency on Apache Commons):

myClass().getResource("resourceFile.txt")??.toURI();

Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.

Linux Crontab Format

MIN HOUR DOM MON DOW CMD

Example::Scheduling a Job For a Specific Time

The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM.

Please note that the time field uses 24 hours format. So, for 8 AM use 8, and for 8 PM use 20.

30 08 10 06 * /home/yourname/full-backup

• 30 – 30th Minute
• 08 – 08 AM
• 10 – 10th Day
• 06 – 6th Month (June)
• *– Every day of the week

In your case, for 2.30PM,

30 14 * * * YOURCMD

1. 30 – 30th Minute
2. 14 – 2PM
3. *– Every day
4. *– Every month
5. *– Every day of the week

Turn on Password Authentication

By default, you need to use keys to ssh into your google compute engine machine, but you can turn on password authentication if you do not need that level of security.

Tip: Use the Open in browser window SSH option from your cloud console to gain access to the machine. Then switch to the root user with sudo su - root to make the configuration changes below.

1. Edit the /etc/ssh/sshd_config file.
2. Change PasswordAuthentication and ChallengeResponseAuthentication to yes.
3. Restart ssh /etc/init.d/ssh restart.

Don't do: mkdir -m 777 -p a/b/c since that will only set permission 777 on the last directory, c; a and b will be created with the default permission from your umask.

Instead to create any new directories with permission 777, run mkdir -p in a subshell where you override the umask:

(umask u=rwx,g=rwx,o=rwx && mkdir -p a/b/c)

Note that this won't change the permissions if any of a, b and c already exist though.

You may work with Integer instead of int, Double instead of double, etc. (such classes exists for all primitive types). Then you may use the operator instanceof, like if(var instanceof Integer){...}

Try from tensorflow.python import keras

with this, you can easily change keras dependent code to tensorflow in one line change.

You can also try from tensorflow.contrib import keras. This works on tensorflow 1.3

Edited: for tensorflow 1.10 and above you can use import tensorflow.keras as keras to get keras in tensorflow.

cleanText = strInputCode.replace(/<\/?[^>]+(>|$)/g, "");

Distilled from this website (web.achive).

This regex looks for <, an optional slash /, one or more characters that are not >, then either > or $ (the end of the line)

Examples:

'<div>Hello</div>' ==> 'Hello'
 ^^^^^     ^^^^^^
'Unterminated Tag <b' ==> 'Unterminated Tag '
                  ^^

But it is not bulletproof:

'If you are < 13 you cannot register' ==> 'If you are '
            ^^^^^^^^^^^^^^^^^^^^^^^^
'<div data="score > 42">Hello</div>' ==> ' 42">Hello'
 ^^^^^^^^^^^^^^^^^^          ^^^^^^

If someone is trying to break your application, this regex will not protect you. It should only be used if you already know the format of your input. As other knowledgable and mostly sane people have pointed out, to safely strip tags, you must use a parser.

If you do not have acccess to a convenient parser like the DOM, and you cannot trust your input to be in the right format, you may be better off using a package like sanitize-html, and also other sanitizers are available.

To update container-selinux I had to install epel-release first:

Add Centos-7 repository

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Install epel-release

yum install epel-release

Update container-selinux

yum install container-selinux

You can also use a small function that will loop through and remove any spaces.

This is very clean and simple.

Public Shared Function RemoveXtraSpaces(strVal As String) As String
     Dim iCount As Integer = 1
     Dim sTempstrVal As String

     sTempstrVal = ""

     For iCount = 1 To Len(strVal)
        sTempstrVal = sTempstrVal + Mid(strVal, iCount, 1).Trim
     Next

     RemoveXtraSpaces = sTempstrVal

     Return RemoveXtraSpaces

End Function

Use filter to get at the elements that have abc.

>>> lst = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
>>> print filter(lambda x: 'abc' in x, lst)
['abc-123', 'abc-456']

You can also use a list comprehension.

>>> [x for x in lst if 'abc' in x]

By the way, don't use the word list as a variable name since it is already used for the list type.

Message queues are asynchronous and can retry a number of times if delivery fails. Use a message queue if the requester doesn't need to wait for a response.

The phrase "web services" make me think of synchronous calls to a distributed component over HTTP. Use web services if the requester needs a response back.

This should do it if memory serves:

List<MyType> fixed = Arrays.asList(new MyType[100]);

I got similar problem

1: I tried to resolve with the answer which is marked correct above But I was not able to get the system setting which was quit amazing (On MacBook).

Most of the time such errors & issues comes because of replacing your grade file with other grade file ,due which gradel does not sync properly and while building the project issue comes . The issue is bascially related to non syncing for platform tools

Solution a: Go to File and then to Your project strucutre -modules -app-Properties -build tool version -click on options which is required for your project (if required build tool version not there chose any other). This will sync the grade file and now you can go to gradel and change target version and build tool version as per your requirement .you will prompted to download the required platform tool to sync it , now click on install tool version and let project to build

Solution b: Try Anuja Ans if you can get option of system setting and install platform tool.

numpy.array is a function that returns a numpy.ndarray. There is no object type numpy.array.

Select the lines you want to comment. Then press Ctrl + /

based on javascript runtime prototype implementation you can use simple arithmetic to subtract dates as in bellow

var sep = new Date(2020, 07, 31, 23, 59, 59);
var today = new Date();
var diffD = Math.floor((sep - today) / (1000 * 60 * 60 * 24));
console.log('Day Diff: '+diffD);

the difference return answer as milliseconds, then you have to convert it by division:

• by 1000 to convert to second
• by 1000×60 convert to minute
• by 1000×60×60 convert to hour
• by 1000×60×60×24 convert to day

In some case NTLM authentication still won't work if given the correct credential.

There's a mechanism which will void NTLM auth within WebClient, see here for more information: System.Net.WebClient doesn't work with Windows Authentication

Post this here to save other's time ;)

The compiler actually adds an argument to non-static methods. It adds a this pointer/reference. This is also the reason why a static method can not use this, because there is no object.

You can do it in multiple ways:
1. Using greater as comparison function :

 #include <bits/stdc++.h>

using namespace std;

int main()
{
    priority_queue<int,vector<int>,greater<int> >pq;
    pq.push(1);
    pq.push(2);
    pq.push(3);

    while(!pq.empty())
    {
        int r = pq.top();
        pq.pop();
        cout<<r<< " ";
    }
    return 0;
}

2. Inserting values by changing their sign (using minus (-) for positive number and using plus (+) for negative number :

int main()
{
    priority_queue<int>pq2;
    pq2.push(-1); //for +1
    pq2.push(-2); //for +2
    pq2.push(-3); //for +3
    pq2.push(4);  //for -4

    while(!pq2.empty())
    {
        int r = pq2.top();
        pq2.pop();
        cout<<-r<<" ";
    }

    return 0;
}

3. Using custom structure or class :

struct compare
{
    bool operator()(const int & a, const int & b)
    {
        return a>b;
    }
};

int main()
{

    priority_queue<int,vector<int>,compare> pq;
    pq.push(1);
    pq.push(2);
    pq.push(3);

    while(!pq.empty())
    {
        int r = pq.top();
        pq.pop();
        cout<<r<<" ";
    }

    return 0;
}

4. Using custom structure or class you can use priority_queue in any order. Suppose, we want to sort people in descending order according to their salary and if tie then according to their age.

    struct people
    {
        int age,salary;

    };
    struct compare{
    bool operator()(const people & a, const people & b)
        {
            if(a.salary==b.salary)
            {
                return a.age>b.age;
            }
            else
            {
                return a.salary>b.salary;
            }

    }
    };
    int main()
    {

        priority_queue<people,vector<people>,compare> pq;
        people person1,person2,person3;
        person1.salary=100;
        person1.age = 50;
        person2.salary=80;
        person2.age = 40;
        person3.salary = 100;
        person3.age=40;


        pq.push(person1);
        pq.push(person2);
        pq.push(person3);

        while(!pq.empty())
        {
            people r = pq.top();
            pq.pop();
            cout<<r.salary<<" "<<r.age<<endl;
    }

5. Same result can be obtained by operator overloading :

   struct people
   {
   int age,salary;
   
   bool operator< (const people & p)const
   {
       if(salary==p.salary)
       {
           return age>p.age;
       }
       else
       {
           return salary>p.salary;
       }
   }};
   

   In main function :

   priority_queue<people> pq;
   people person1,person2,person3;
   person1.salary=100;
   person1.age = 50;
   person2.salary=80;
   person2.age = 40;
   person3.salary = 100;
   person3.age=40;
   
   
   pq.push(person1);
   pq.push(person2);
   pq.push(person3);
   
   while(!pq.empty())
   {
       people r = pq.top();
       pq.pop();
       cout<<r.salary<<" "<<r.age<<endl;
   }
   

Make sure you have installed 'make' tool through Cygwin's installer.

Set Label's AutoSize property to False, TextAlign property to MiddleCenter and Dock property to Fill.

This will work in Chrome

// get your input
var input = document.getElementById('txt206451');
// get it's (first) label
var label = input.labels[0];
// change it's content
label.textContent = 'thanks'

But after looking, labels doesn't seem to be widely supported..

You can use querySelector

// get txt206451's (first) label
var label = document.querySelector('label[for="txt206451"]');
// change it's content
label.textContent = 'thanks'

Put it in .gitignore. But from the gitignore(5) man page:

  ·   If the pattern does not contain a slash /, git treats it as a shell
       glob pattern and checks for a match against the pathname relative
       to the location of the .gitignore file (relative to the toplevel of
       the work tree if not from a .gitignore file).

  ·   Otherwise, git treats the pattern as a shell glob suitable for
       consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in
       the pattern will not match a / in the pathname. For example,
       "Documentation/*.html" matches "Documentation/git.html" but not
       "Documentation/ppc/ppc.html" or
       "tools/perf/Documentation/perf.html".

So, either specify the full path to the appropriate *.pyc entry, or put it in a .gitignore file in any of the directories leading from the repository root (inclusive).

'Fraid so. I'd make an HTML page with a stylesheet, then use jQuery to apply the stylesheet to the style attr of each element. Something like this:

var styleAttributes = ['color','font-size']; // all the attributes you've applied in your stylesheet
for (i in styleAttributes) {
    $('body *').css(styleAttributes[i],function () {
        $(this).css(styleAttributes[i]);
    });
}

Then copy the DOM and use that in the email.

In my situation the following code was embedded into a php file.

var PreventExitPop = true;
function ExitPop() {
  if (PreventExitPop != false) {
    return "Hold your horses! \n\nTake the time to reserve your place.Registrations might become paid or closed completely to newcomers!"
  }
}
window.onbeforeunload = ExitPop;

So I opened the console and write the following

PreventExitPop = false

This solved the problem. So, find out the JavaScript code and find the variable(s) and assign them to an appropriate "value" which in my case was "false"

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

Could not commit JPA transaction: Transaction marked as rollbackOnly

This exception occurs when you invoke nested methods/services also marked as @Transactional. JB Nizet explained the mechanism in detail. I'd like to add some scenarios when it happens as well as some ways to avoid it.

Suppose we have two Spring services: Service1 and Service2. From our program we call Service1.method1() which in turn calls Service2.method2():

class Service1 {
    @Transactional
    public void method1() {
        try {
            ...
            service2.method2();
            ...
        } catch (Exception e) {
            ...
        }
    }
}

class Service2 {
    @Transactional
    public void method2() {
        ...
        throw new SomeException();
        ...
    }
}

SomeException is unchecked (extends RuntimeException) unless stated otherwise.

Scenarios:

1. Transaction marked for rollback by exception thrown out of method2. This is our default case explained by JB Nizet.

2. Annotating method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

3. Annotating both method1 and method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

4. Annotating method2 with @Transactional(noRollbackFor = SomeException) prevents marking transaction for rollback (no exception thrown when exiting from method1).

5. Suppose method2 belongs to Service1. Invoking it from method1 does not go through Spring's proxy, i.e. Spring is unaware of SomeException thrown out of method2. Transaction is not marked for rollback in this case.

6. Suppose method2 is not annotated with @Transactional. Invoking it from method1 does go through Spring's proxy, but Spring pays no attention to exceptions thrown. Transaction is not marked for rollback in this case.

7. Annotating method2 with @Transactional(propagation = Propagation.REQUIRES_NEW) makes method2 start new transaction. That second transaction is marked for rollback upon exit from method2 but original transaction is unaffected in this case (no exception thrown when exiting from method1).

8. In case SomeException is checked (does not extend RuntimeException), Spring by default does not mark transaction for rollback when intercepting checked exceptions (no exception thrown when exiting from method1).

See all scenarios tested in this gist.

This other solution for covert datetime to unixtimestampmillis C#.

private static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

public static long GetCurrentUnixTimestampMillis()
{
    DateTime localDateTime, univDateTime;
    localDateTime = DateTime.Now;          
    univDateTime = localDateTime.ToUniversalTime();
    return (long)(univDateTime - UnixEpoch).TotalMilliseconds;
} 

To fix your code you can simply change [Cov] to Cov.values, the first parameter of pd.DataFrame will become a multi-dimensional numpy array:

Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')

But the smartest solution still is use pd.read_excel with header=None and names=columns_list.

Assuming you have your debug view just how you like it and don't want to have to reset it everytime this bug appears, try this. This assumes your "Debug View" has both "Expressions" and "Variables" views open.

Double-Click the Expressions tab (the actual tab with the text, not the 'window bar'). This will maximise it. Repeat to restore it to previous size/location. That should reset everything except Expressions. Repeat for the variables tab and it will reset expressions.

Just zero off the time element of the date. e.g.

SELECT DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)

I've used GetDate as that's an MSSQL function, as you've tagged, but Now() is probably MySQL or you're using the ODBC function call, still should work if you just replace one with the other.

var array = [[1, "grape", 42], [2, "fruit", 9]];

array.sort(function(a, b)
{
    // a and b will here be two objects from the array
    // thus a[1] and b[1] will equal the names

    // if they are equal, return 0 (no sorting)
    if (a[1] == b[1]) { return 0; }
    if (a[1] > b[1])
    {
        // if a should come after b, return 1
        return 1;
    }
    else
    {
        // if b should come after a, return -1
        return -1;
    }
});

The sort function takes an additional argument, a function that takes two arguments. This function should return -1, 0 or 1 depending on which of the two arguments should come first in the sorting. More info.

I also fixed a syntax error in your multidimensional array.

Use the Server.HtmlEncode("yourtext");

If your Vim is not compiled with clipboards, you wish to copy selected text instead of entire lines, you do not want to install MacVim or other GUI, the simplest solution is to add this line to your .vimrc:

map <C-c> y:e ~/clipsongzboard<CR>P:w !pbcopy<CR><CR>:bdelete!<CR>

To use it, simply visually select the text you want to copy, and then Control-C. If you want a full explanation of this line read "How to Copy to clipboard on vim".

Sorry for I did not explain my answer really well at beginning. There is another way to add an new column to an existing dataframe. 1st step, make a new empty data frame (with all the columns in your data frame, plus a new or few columns you want to add) called df_temp 2nd step, combine the df_temp and your data frame.

df_temp = pd.DataFrame(columns=(df_null.columns.tolist() + ['empty']))
df = pd.concat([df_temp, df])

It might be the best solution, but it is another way to think about this question.

the reason of I am using this method is because I am get this warning all the time:

: SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
  df["empty1"], df["empty2"] = [np.nan, ""]

great I found the way to disable the Warning

pd.options.mode.chained_assignment = None 

If you are using Xcode 6 and designing for iOS 8, none of these solutions are correct. To get your iPhone-only views to be sized correctly, don't turn off size classes, don't turn off inferred metrics, and don't set constraints (yet). Instead, use the size class control, which is an easy to miss text button at the bottom of Interface Builder that initially reads "wAny hAny".

Click the button, and choose Compact Width, Regular Height. This resize your views and cover all iPhone portrait orientations. Apple's docs here: https://developer.apple.com/library/ios/recipes/xcode_help-IB_adaptive_sizes/chapters/SelectingASizeClass.html or search on "Selecting a Size Class in Interface Builder"

For Nginx, the only thing that worked for me was adding this header:

add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';

Along with the Access-Control-Allow-Origin header:

add_header 'Access-Control-Allow-Origin' '*';

Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.

C# will allow you to have a string split over multiple lines, the term is called verbatim literal:

string myString = @"this is a
                    test
                   to see how long my string
                   can be



                    and it can be quite long";

If you are looking for the alternative to & _ from VB, use the + to join your lines.

You can only use just the name of the type (with its namespace, of course) if the type is in mscorlib or the calling assembly. Otherwise, you've got to include the assembly name as well:

Type type = Type.GetType("Namespace.MyClass, MyAssembly");

If the assembly is strongly named, you've got to include all that information too. See the documentation for Type.GetType(string) for more information.

Alternatively, if you have a reference to the assembly already (e.g. through a well-known type) you can use Assembly.GetType:

Assembly asm = typeof(SomeKnownType).Assembly;
Type type = asm.GetType(namespaceQualifiedTypeName);

I know that this topic is quite old, but this need is still alive. I read many documents, forum and script and build a new advanced one which supports compressed and uncompressed pdf :

If you're using .NET 4.5 you can use the new async/await framework to sleep without locking the thread.

How it works is that you mark the function in need of asynchronous operations, with the async keyword. This is just a hint to the compiler. Then you use the await keyword on the line where you want your code to run asynchronously and your program will wait without locking the thread or the UI. The method you call (on the await line) has to be marked with an async keyword as well and is usually named ending with Async, as in ImportFilesAsync.

What you need to do in your example is:

1. Make sure your program has .Net Framework 4.5 as Target Framework
2. Mark your function that needs to sleep with the async keyword (see example below)
3. Add using System.Threading.Tasks; to your code.

Your code is now ready to use the Task.Delay method instead of the System.Threading.Thread.Sleep method (it is possible to use await on Task.Delay because Task.Delay is marked with async in its definition).

private async void button1_Click(object sender, EventArgs e)
{
    textBox1.Text += "\r\nThread Sleeps!";
    await Task.Delay(3000);
    textBox1.Text += "\r\nThread awakens!";
}

Here you can read more about Task.Delay and Await.

Apache 2.4.3 (or maybe slightly earlier) added a new security feature that often results in this error. You would also see a log message of the form "client denied by server configuration". The feature is requiring an authorized user identity to access a directory. It is turned on by DEFAULT in the httpd.conf that ships with Apache. You can see the enabling of the feature with the directive

Require all denied

This basically says to deny access to all users. To fix this problem, either remove the denied directive (or much better) add the following directive to the directories you want to grant access to:

Require all granted

as in

<Directory "your directory here">
   Order allow,deny
   Allow from all
   # New directive needed in Apache 2.4.3: 
   Require all granted
</Directory>

In Visual Studio 2015 this shortcut opens a preview of the definition which even works through typedefs and #defines.

Ctrl + , (comma)

you could do like this:

return inObj == DBNull.Value ? "" : (Convert.ToDateTime(inObj)).ToString("MM/dd/yyyy").ToString();

When using Python 2.4, try

inf = float("9e999")
nan = inf - inf

I am facing the issue when I was porting the simplejson to an embedded device which running the Python 2.4, float("9e999") fixed it. Don't use inf = 9e999, you need convert it from string. -inf gives the -Infinity.

This is what I came op for a thread safe bounded blocking queue.

Access 2010 has both stored procedures, and also has table triggers. And, both features are available even when you not using a server (so, in 100% file based mode).

If you using SQL Server with Access, then of course the stored procedures are built using SQL Server and not Access.

For Access 2010, you open up the table (non-design view), and then choose the table tab. You see options there to create store procedures and table triggers.

For example:

Note that the stored procedure language is its own flavor just like Oracle or SQL Server (T-SQL). Here is example code to update an inventory of fruits as a result of an update in the fruit order table

Keep in mind these are true engine-level table triggers. In fact if you open up that table with VB6, VB.NET, FoxPro or even modify the table on a computer WITHOUT Access having been installed, the procedural code and the trigger at the table level will execute. So, this is a new feature of the data engine jet (now called ACE) for Access 2010. As noted, this is procedural code that runs, not just a single statement.

You can improve read speed by using a BufferedStream, like this:

using (FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
using (BufferedStream bs = new BufferedStream(fs))
using (StreamReader sr = new StreamReader(bs))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {

    }
}

March 2013 UPDATE

I recently wrote code for reading and processing (searching for text in) 1 GB-ish text files (much larger than the files involved here) and achieved a significant performance gain by using a producer/consumer pattern. The producer task read in lines of text using the BufferedStream and handed them off to a separate consumer task that did the searching.

I used this as an opportunity to learn TPL Dataflow, which is very well suited for quickly coding this pattern.

Why BufferedStream is faster

A buffer is a block of bytes in memory used to cache data, thereby reducing the number of calls to the operating system. Buffers improve read and write performance. A buffer can be used for either reading or writing, but never both simultaneously. The Read and Write methods of BufferedStream automatically maintain the buffer.

December 2014 UPDATE: Your Mileage May Vary

Based on the comments, FileStream should be using a BufferedStream internally. At the time this answer was first provided, I measured a significant performance boost by adding a BufferedStream. At the time I was targeting .NET 3.x on a 32-bit platform. Today, targeting .NET 4.5 on a 64-bit platform, I do not see any improvement.

I came across a case where streaming a large, generated CSV file to the Response stream from an ASP.Net MVC action was very slow. Adding a BufferedStream improved performance by 100x in this instance. For more see Unbuffered Output Very Slow

I had the same problems. I solved it: I went to https://www.google.com/recaptcha/admin, clicked on the domain and then went to key settings at the bottom.

There I disabled the option below Domain Name Validation Verify the origin of reCAPTCHA solution.

Clicked on save and captcha started working.

It should be something like...

<xsl:if test="contains($hhref, '1234')">

(not tested)

See w3schools (always a good reference BTW)

I think the solution from Rajesh is nearly perfect, but I think it is better traverse subviews from top to bottom, I changed to the following:

+ (UIViewController *)topViewController:(UIViewController *)viewController{

    if (viewController.presentedViewController)
    {

            UIViewController *presentedViewController = viewController.presentedViewController;
            return [self topViewController:presentedViewController];
     } 
     else if ([viewController isKindOfClass:[UITabBarController class]])
     {

            UITabBarController *tabBarController = (UITabBarController *)viewController;
            return [self topViewController:tabBarController.selectedViewController];
    }

         else if ([viewController isKindOfClass:[UINavigationController class]])
    {   

            UINavigationController *navController = (UINavigationController *)viewController;

            return [self topViewController:navController.visibleViewController];
    }

    // Handling UIViewController's added as subviews to some other views.
    else {

        NSInteger subCount = [viewController.view subviews].count - 1;

        for (NSInteger index = subCount; index >=0 ; --index)
        {

            UIView *view = [[viewController.view subviews] objectAtIndex:index];

            id subViewController = [view nextResponder];    // Key property which most of us are unaware of / rarely use.

            if ( subViewController && [subViewController isKindOfClass:[UIViewController class]])
            {
                return [self topViewController:subViewController];
            }
        }
        return viewController;
    }
}

I know it's been a long time, but still the most obvious solution via fold (aka reduce in js) is missing, for the sake of completeness i'll leave it here:

function mapO(f, o) {
  return Object.keys(o).reduce((acc, key) => {
    acc[key] = f(o[key])
    return acc
  }, {})
}

You can use these solutions :

CSS rules applies to all tags that have following two classes :

.left.ui-class-selector {
    /*style here*/
}

CSS rules applies to all tags that have <li> with following two classes :

li.left.ui-class-selector {
   /*style here*/
}

jQuery solution :

$("li.left.ui-class-selector").css("color", "red");

Javascript solution :

document.querySelector("li.left.ui-class-selector").style.color = "red";

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.search, menu);


    MenuItem myActionMenuItem = menu.findItem( R.id.action_search);
    SearchView searchView = (SearchView) myActionMenuItem.getActionView();

    EditText searchEditText = (EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchEditText.setTextColor(Color.WHITE); //You color here

<% @images.each_with_index do |page, index| %>

<% end %>

You can't create pseudo elements in inline css.

However, if you can create a pseudo element in a stylesheet, then there's a way to style it inline by setting an inline style to its parent element, and then using inherit keyword to style the pseudo element, like this:

<parent style="background-image:url(path/to/file); background-size:0px;"></p>

<style> 
   parent:before{
      content:'';
      background-image:inherit;
      (other)
   }
</style>

sometimes this can be handy.

A grammar is context-free if all production rules have the form: A (that is, the left side of a rule can only be a single variable; the right side is unrestricted and can be any sequence of terminals and variables). We can define a grammar as a 4-tuple where V is a finite set (variables), _ is a finite set (terminals), S is the start variable, and R is a finite set of rules, each of which is a mapping V
regular grammar is either right or left linear, whereas context free grammar is basically any combination of terminals and non-terminals. hence we can say that regular grammar is a subset of context-free grammar. After these properties we can say that Context Free Languages set also contains Regular Languages set

Take a look at the Tiny But Strong templating system. It's generally used for templating HTML but there's an extension that works with XML files. I use this extensively for creating reports where I can have one code file and two template files - htm and xml - and the user can then choose whether to send a report to screen or spreadsheet.

Another advantage is you don't have to code the xml from scratch, in some cases I've been wanting to export very large complex spreadsheets, and instead of having to code all the export all that is required is to save an existing spreadsheet in xml and substitute in code tags where data output is required. It's a quick and a very efficient way to work.

Answer is : docker network prune

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

That's why your example uses Active X, which bypasses the JavaScript security issues.

So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.

Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.

I know you've found another solution, but for those like me who find this question, looking for the same thing, it can be achieved with requests as follows:

Firstly, as Marcus did, check the source of the login form to get three pieces of information - the url that the form posts to, and the name attributes of the username and password fields. In his example, they are inUserName and inUserPass.

Once you've got that, you can use a requests.Session() instance to make a post request to the login url with your login details as a payload. Making requests from a session instance is essentially the same as using requests normally, it simply adds persistence, allowing you to store and use cookies etc.

Assuming your login attempt was successful, you can simply use the session instance to make further requests to the site. The cookie that identifies you will be used to authorise the requests.

Example

import requests

# Fill in your details here to be posted to the login form.
payload = {
    'inUserName': 'username',
    'inUserPass': 'password'
}

# Use 'with' to ensure the session context is closed after use.
with requests.Session() as s:
    p = s.post('LOGIN_URL', data=payload)
    # print the html returned or something more intelligent to see if it's a successful login page.
    print p.text

    # An authorised request.
    r = s.get('A protected web page url')
    print r.text
        # etc...

use this : export MYVAR="$(dirname "$(dirname "$(dirname "$(dirname $PWD)")")")" if you want 4th parent directory

export MYVAR="$(dirname "$(dirname "$(dirname $PWD)")")" if you want 3rd parent directory

export MYVAR="$(dirname "$(dirname $PWD)")" if you want 2nd parent directory

i wanted to ask if Android Devices uses the network time protocol (ntp) to synchronize the time.

For general time synchronization, devices with telephony capability, where the wireless provider provides NITZ information, will use NITZ. My understanding is that NTP is used in other circumstances: NITZ-free wireless providers, WiFi-only, etc.

Your cited blog post suggests another circumstance: on-demand time synchronization in support of GPS. That is certainly conceivable, though I do not know whether it is used or not.

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

I also have the same problem, and the solution is I didn't bind the event in my onClick. so when it renders for the first time and the data is more, which ends up calling the state setter again, which triggers React to call your function again and so on.

export default function Component(props) {

function clickEvent (event, variable){
    console.log(variable);
}

return (
    <div>
        <IconButton
            key="close"
            aria-label="Close"
            color="inherit"
            onClick={e => clickEvent(e, 10)} // or you can call like this:onClick={() => clickEvent(10)} 
        >
    </div>
)
}

Yes it will get called. That's the whole point of having a finally keyword. If jumping out of the try/catch block could just skip the finally block it was the same as putting the System.out.println outside the try/catch.

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.

If you use angular remove the ng-storage profile from your browser console. It is not a general solution bit It worked in my case.

If there is no selection, you can use the properties .selectionStart or .selectionEnd (with no selection they're equal).

var cursorPosition = $('#myTextarea').prop("selectionStart");

Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.

I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.

How about

$('#county').append(
    $('<option />')
        .text('Select a city / town in Sweden')
        .val(''),
    $('<option />')
        .text('Melbourne')
        .val('Melbourne')
);

Can't stand aside,

So we have linear system:

A₁ * x + B₁ * y = C₁
A₂ * x + B₂ * y = C₂

let's do it with Cramer's rule, so solution can be found in determinants:

x = D_x/D
y = D_y/D

where D is main determinant of the system:

A₁ B₁
A₂ B₂

and D_x and D_y can be found from matricies:

C₁ B₁
C₂ B₂

and

A₁ C₁
A₂ C₂

(notice, as C column consequently substitues the coef. columns of x and y)

So now the python, for clarity for us, to not mess things up let's do mapping between math and python. We will use array L for storing our coefs A, B, C of the line equations and intestead of pretty x, y we'll have [0], [1], but anyway. Thus, what I wrote above will have the following form further in the code:

for D

L1[0] L1[1]
L2[0] L2[1]

for D_x

L1[2] L1[1]
L2[2] L2[1]

for D_y

L1[0] L1[2]
L2[0] L2[2]

Now go for coding:

line - produces coefs A, B, C of line equation by two points provided,
intersection - finds intersection point (if any) of two lines provided by coefs.

from __future__ import division 

def line(p1, p2):
    A = (p1[1] - p2[1])
    B = (p2[0] - p1[0])
    C = (p1[0]*p2[1] - p2[0]*p1[1])
    return A, B, -C

def intersection(L1, L2):
    D  = L1[0] * L2[1] - L1[1] * L2[0]
    Dx = L1[2] * L2[1] - L1[1] * L2[2]
    Dy = L1[0] * L2[2] - L1[2] * L2[0]
    if D != 0:
        x = Dx / D
        y = Dy / D
        return x,y
    else:
        return False

Usage example:

L1 = line([0,1], [2,3])
L2 = line([2,3], [0,4])

R = intersection(L1, L2)
if R:
    print "Intersection detected:", R
else:
    print "No single intersection point detected"

For Different screen size, The following is a list of resource directories in an application that provides different layout designs for different screen sizes and different bitmap drawables for small, medium, high, and extra high density screens.

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

res/drawable-mdpi/my_icon.png        // bitmap for medium density
res/drawable-hdpi/my_icon.png        // bitmap for high density
res/drawable-xhdpi/my_icon.png       // bitmap for extra high density

The following code in the Manifest supports all dpis.

<supports-screens android:smallScreens="true" 
          android:normalScreens="true" 
          android:largeScreens="true"
          android:xlargeScreens="true"
          android:anyDensity="true" />

You can see collation settings for each table like the following code:

SELECT t.name TableName, c.name ColumnName, collation_name  
FROM sys.columns c  
INNER JOIN sys.tables t on c.object_id = t.object_id where t.name = 'name of table';

You can use:

List<String> list = Files.readAllLines(new File("input.txt").toPath(), Charset.defaultCharset() );

Note : This answer is now out-of-date. This changes the theme in "preview" only as @imjohnking and @john-ktejik pointed out. As @Shahzeb mentioned, theme can modified in res>values>styles

Android Studio 0.8.2 provides a slightly easier way to change the theme. In the preview window, you can select the theme of "Holo.Light.DarkActionBar" by clicking on the theme combo box just above the phone.

Or do a ctrl + click on the @style/AppTheme in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

• Theme.Holo for a "dark" theme.
• Theme.Holo.Light for a "light" theme.

When using the Support Library, you must instead use the Theme.AppCompat themes:

• Theme.AppCompat for the "dark" theme.
• Theme.AppCompat.Light for the "light" theme.
• Theme.AppCompat.Light.DarkActionBar for the light theme with a dark action bar.

^{(ansible 2.9.6 ansible-lint 4.2.0)}

See ansible-lint default rules. The condition below causes E602 Don’t compare to empty string

    when: test_myscript.stderr != ""

Correct syntax and also "Ansible Galaxy Warning-Free" option is

    when: test_myscript.stderr | length > 0

Quoting from source code

"Use when: var|length > 0 rather than when: var != "" (or ' 'conversely when: var|length == 0 rather than when: var == "")"

Notes

1. Test empty bare variable e.g.

    - debug:
        msg: "Empty string '{{ var }}' evaluates to False"
      when: not var
      vars:
        var: ''

    - debug:
        msg: "Empty list {{ var }} evaluates to False"
      when: not var
      vars:
        var: []

give

    "msg": "Empty string '' evaluates to False"
    "msg": "Empty list [] evaluates to False"

2. But, testing non-empty bare variable string depends on CONDITIONAL_BARE_VARS. Setting ANSIBLE_CONDITIONAL_BARE_VARS=false the condition works fine but setting ANSIBLE_CONDITIONAL_BARE_VARS=true the condition will fail

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var
      vars:
        var: 'abc'

gives

fatal: [localhost]: FAILED! => 
  msg: |-
    The conditional check 'var' failed. The error was: error while 
    evaluating conditional (var): 'abc' is undefined

Explicit cast to Boolean prevents the error but evaluates to False i.e. will be always skipped (unless var='True'). When the filter bool is used the options ANSIBLE_CONDITIONAL_BARE_VARS=true and ANSIBLE_CONDITIONAL_BARE_VARS=false have no effect

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var|bool
      vars:
        var: 'abc'

gives

skipping: [localhost]

3. Quoting from Porting guide 2.8 Bare variables in conditionals

  - include_tasks: teardown.yml
    when: teardown

  - include_tasks: provision.yml
    when: not teardown

" based on a variable you define as a string (with quotation marks around it):"

• In Ansible 2.7 and earlier, the two conditions above evaluated as True and False respectively if teardown: 'true'

• In Ansible 2.7 and earlier, both conditions evaluated as False if teardown: 'false'

• In Ansible 2.8 and later, you have the option of disabling conditional bare variables, so when: teardown always evaluates as True and when: not teardown always evaluates as False when teardown is a non-empty string (including 'true' or 'false')

4. Quoting from CONDITIONAL_BARE_VARS

One option is to type [command] + [shift] + [p] (or the equivalent) and then type 'indentation'. The top result should be 'Indendtation: Reindent Lines'. Press [enter] and it will format the document.

Another option is to install the Emmet plugin (http://emmet.io/), which will provide not only better formatting, but also a myriad of other incredible features. To get the output you're looking for using Sublime Text 3 with the Emmet plugin requires just the following:

p [tab][enter] Hello world!

When you type p [tab] Emmet expands it to:

<p></p>

Pressing [enter] then further expands it to:

<p>

</p>

With the cursor indented and on the line between the tags. Meaning that typing text results in:

<p>
    Hello, world!
</p>

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

You can easily do this by:

::variableName.isInitialized

or

this::variableName.isInitialized

But if you are inside a listener or inner class, do this:

this@OuterClassName::variableName.isInitialized

Note: The above statements work fine if you are writing them in the same file(same class or inner class) where the variable is declared but this will not work if you want to check the variable of other class (which could be a superclass or any other class which is instantiated), for ex:

class Test {
    lateinit var str:String
}

And to check if str is initialized:

What we are doing here: checking isInitialized for field str of Test class in Test2 class. And we get an error backing field of var is not accessible at this point. Check a question already raised about this.

How To: Configure MachineKey in ASP.NET 2.0 - Web Farm Deployment Considerations

Web Farm Deployment Considerations

If you deploy your application in a Web farm, you must ensure that the configuration files on each server share the same value for validationKey and decryptionKey, which are used for hashing and decryption respectively. This is required because you cannot guarantee which server will handle successive requests.

With manually generated key values, the settings should be similar to the following example.

<machineKey  
validationKey="21F090935F6E49C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7
               AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B"       

decryptionKey="ABAA84D7EC4BB56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F"
validation="SHA1"
decryption="AES"
/>

If you want to isolate your application from other applications on the same server, place the in the Web.config file for each application on each server in the farm. Ensure that you use separate key values for each application, but duplicate each application's keys across all servers in the farm.

In short, to set up the machine key refer the following link: Setting Up a Machine Key - Orchard Documentation.

Setting Up the Machine Key Using IIS Manager

If you have access to the IIS management console for the server where Orchard is installed, it is the easiest way to set-up a machine key.

Start the management console and then select the web site. Open the machine key configuration:

The machine key control panel has the following settings:

Uncheck "Automatically generate at runtime" for both the validation key and the decryption key.

Click "Generate Keys" under "Actions" on the right side of the panel.

Click "Apply".

and add the following line to the web.config file in all the webservers under system.web tag if it does not exist.

<machineKey  
    validationKey="21F0SAMPLEKEY9C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7
                   AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B"           
    decryptionKey="ABAASAMPLEKEY56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F"
    validation="SHA1"
    decryption="AES"
/>

Please make sure that you have a permanent backup of the machine keys and web.config file

You should separate out all the code that will do stuff from the service project into a separate project, and then make a test application that you can run and debug normally.

The service project would be just the shell needed to implement the service part of it.

For installing multiple packages on the command line, just pass them as a space-delimited list, e.g.:

pip install wsgiref boto

For installing from a text file, then, from pip install --help:

-r FILENAME, --requirement=FILENAME

Install all the packages listed in the given requirements file. This option can be used multiple times.

Take a look at the pip documentation regarding requirements files for their general layout and syntax - note that you can generate one based on current environment / site-packages with pip freeze if you want a quick example - e.g. (based on having installed wsgiref and boto in a clean virtualenv):

$ pip freeze
boto==2.3.0
wsgiref==0.1.2

The problem is that you assigned a fixed width to your .wrap DIV. The DIV itself is centered (you can see that when you add a border to it) but the DIV is just too wide. In other words the content does not fill the whole width of the DIV.

To solve the problem you have to make sure, that the .wrap DIV is only as wide as it's content.

To achieve that you have to remove the floating in the content elements and set the display property of the block levels elements to inline:

#partners .wrap {
 display: inline;
} 

.wrap { margin: 0 auto; position: relative;}

#partners h2 {
color: #A6A5A5;
font-weight: normal;
margin: 2px 15px 0 0;
display: inline;
}

#partners ul {
display: inline;
}

#partners li {display: inline}

Make sure you deactivate the virtual environment or restart Anaconda Prompt. Use the following command to remove virtual environment:

$ conda env remove --name $MyEnvironmentName

Alternatively, you can go to the

C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\envs\MYENVIRONMENTNAME

(that's the default file path) and delete the folder manually.

I think you should change that like so:

<input value={this.state.value} onChange={(e) => {this.handleChange(e)}}/>

That is in principle the same as onClick={this.handleClick.bind(this)} as you did on the button.

So if you want to call handleChange() when the button is clicked, than:

<button onClick={this.handleChange.bind(this)}>Change Input</button>

or

handleClick () {
  this.setState({value: 'another random text'});
  this.handleChange();
}

I was only able to fix this by temporary deleting my repo's .gitattributes file (which defined * text=auto and *.c text).

I ran git status after deleting and the modifications were gone. They didn't return even after .gitattributes was put back in place.

If all you're doing is attaching a string, you could do it in just 2 lines:

mail.Attachments.Add(Attachment.CreateAttachmentFromString("1,2,3", "text/csv");
mail.Attachments.Last().ContentDisposition.FileName = "filename.csv";

I wasn't able to get mine to work using our mail server with StreamWriter.
I think maybe because with StreamWriter you're missing a lot of file property information and maybe our server didn't like what was missing.
With Attachment.CreateAttachmentFromString() it created everything I needed and works great!

Otherwise, I'd suggest taking your file that is in memory and opening it using MemoryStream(byte[]), and skipping the StreamWriter all together.

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.feature_wrapper span {
    float: left;
    clear: left;
    display:inline
}

EDIT: now browsers have better support you can make use of the do inline-block.

.feature_wrapper span {
    display:inline-block;
    *display:inline; *zoom:1;
}

Depending on the text-align this will appear as through its inline while also acting like a block element.

I like to use the recursive pattern for this scenario. For example, something like this:

// If config is an array of queries
var config = JSON.parse(queries.querrryArray);   

// Array of results
var results;

processQueries(config);

function processQueries(queries) {
    var searchQuery;

    if (queries.length == 0) {
        // All queries complete
        res.writeHead(200, {'content-type': 'application/json'});
        res.end(JSON.stringify({results: results}));
        return;
    }

    searchQuery = queries.pop();

    search(searchQuery, function(result) {
        results.push(JSON.stringify({result: result}); 
        processQueries();            
    });

}

processQueries is a recursive function that will pull a query element out of an array of queries to process. Then the callback function calls processQueries again when the query is complete. The processQueries knows to end when there are no queries left.

It is easiest to do this using arrays, but it could be modified to work with object key/values I imagine.

A simple solution without using external modules:

from datetime import datetime, timezone

dt = datetime(2008, 1, 1, 0, 0, 0, 0)
int(dt.replace(tzinfo=timezone.utc).timestamp())

It really depends on the situation, for me its in fpm as I'm using PHP5-FPM. A solution to your problem could be a universal php.ini and then using a symbolic link created like:

ln -s /etc/php5/php.ini php.ini

Then any modifications you make will be in one general .ini file. This is probably not really the best solution though, you might want to look into modifying some configuration so that you literally use one file, on one location. Not multiple locations hacked together.

Just handle the form submission on the submit event, and return false:

$('#contactForm').submit(function () {
 sendContactForm();
 return false;
});

You don't need any more the onclick event on the submit button:

<input class="submit" type="submit" value="Send" />

One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:

Array(8).fill().map((_, i) => i * i);

Getting total rows in a query result...

You could just iterate the result and count them. You don't say what language or client library you are using, but the API does provide a mysql_num_rows function which can tell you the number of rows in a result.

This is exposed in PHP, for example, as the mysqli_num_rows function. As you've edited the question to mention you're using PHP, here's a simple example using mysqli functions:

$link = mysqli_connect("localhost", "user", "password", "database");

$result = mysqli_query($link, "SELECT * FROM table1");
$num_rows = mysqli_num_rows($result);

echo "$num_rows Rows\n";

Getting a count of rows matching some criteria...

Just use COUNT(*) - see Counting Rows in the MySQL manual. For example:

SELECT COUNT(*) FROM foo WHERE bar= 'value';

Get total rows when LIMIT is used...

If you'd used a LIMIT clause but want to know how many rows you'd get without it, use SQL_CALC_FOUND_ROWS in your query, followed by SELECT FOUND_ROWS();

SELECT SQL_CALC_FOUND_ROWS * FROM foo
   WHERE bar="value" 
   LIMIT 10;

SELECT FOUND_ROWS();

For very large tables, this isn't going to be particularly efficient, and you're better off running a simpler query to obtain a count and caching it before running your queries to get pages of data.

If you have a seeder in your database, run php artisan migrate:fresh --seed

FATAL:  could not load server certificate file "/etc/ssl/certs/ssl-cert-snakeoil.pem": No such file or directory
LOG:  database system is shut down
pg_ctl: could not start server

I have a missing ssl-cert-snakeoil.pem file so i created it using make-ssl-cert generate-default-snakeoil --force-overwrite And it worked fine.

just take the string and use the JavaScriptSerializer to deserialize it into a native object. For example, having this json:

string json = "[{Name:'John Simith',Age:35},{Name:'Pablo Perez',Age:34}]"; 

You'd need to create a C# class called, for example, Person defined as so:

public class Person
{
 public int Age {get;set;}
 public string Name {get;set;}
}

You can now deserialize the JSON string into an array of Person by doing:

JavaScriptSerializer js = new JavaScriptSerializer();
Person [] persons =  js.Deserialize<Person[]>(json);

Here's a link to JavaScriptSerializer documentation.

Note: my code above was not tested but that's the idea Tested it. Unless you are doing something "exotic", you should be fine using the JavascriptSerializer.

Does this help you:

<script type="text/javascript">
window.onerror = function() {
    alert("Error caught");
};

xxx();
</script>

I'm not sure how it handles Flash errors though...

Update: it doesn't work in Opera, but I'm hacking Dragonfly right now to see what it gets. Suggestion about hacking Dragonfly came from this question:

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

function fnPopUpWindow(pageId) {
     popupwindow("hellowWorld.php?id="+pageId, "printViewer", "500", "300");
}

function popupwindow(url, title, w, h) {
    var left = Math.round((screen.width/2)-(w/2));
    var top = Math.round((screen.height/2)-(h/2));
    return window.open(url, title, 'toolbar=no, location=no, directories=no, status=no, '
            + 'menubar=no, scrollbars=yes, resizable=no, copyhistory=no, width=' + w 
            + ', height=' + h + ', top=' + top + ', left=' + left);
}

<a href="javascript:void(0);" onclick="fnPopUpWindow('10');">Print Me</a>

Note: you have to use Math.round for getting the exact integer of width and height.

Why :not just use two :not:

input:not([type="radio"]):not([type="checkbox"])

_{Yes, it is intentional}

Because int is a ValueType then you can use the following code:

if(Age == default(int) || Age == null)

or

if(Age.HasValue && Age != 0) or if (!Age.HasValue || Age == 0)

My 2 cents:

select DATEADD(DAY,-1,DATEADD(MONTH,1,DATEADD(day,(0-(DATEPART(dd,'2008-02-12')-1)),'2008-02-12')))

The simplest supported solution is to either use margin

.element {
  display: block;
  margin: 0px auto;
}

Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto if it did exist.

CSS

.element_wrapper {
  display: block;
  margin: 0px auto;
}
.element {
  background: blue;
}

HTML

<div class="element_wrapper">
  <div class="element">
    Hello world
  </div>
</div>

I'd recommend reading the header directly from the driver, not through Spark. Two reasons for this: 1) It's a single line. There's no advantage to a distributed approach. 2) We need this line in the driver, not the worker nodes.

It goes something like this:

// Ridiculous amount of code to read one line.
val uri = new java.net.URI(filename)
val conf = sc.hadoopConfiguration
val fs = hadoop.fs.FileSystem.get(uri, conf)
val path = new hadoop.fs.Path(filename)
val stream = fs.open(path)
val source = scala.io.Source.fromInputStream(stream)
val header = source.getLines.head

Now when you make the RDD you can discard the header.

val csvRDD = sc.textFile(filename).filter(_ != header)

Then we can make an RDD from one column, for example:

val idx = header.split(",").indexOf(columnName)
val columnRDD = csvRDD.map(_.split(",")(idx))

Is the drive E a mapped drive? Then, it can be created by another account other than the user account. This may be the cause of the error.

I feel your pain and I wasted all night/morning trying to figure this out. With sheer brute force I figured out a solution. Call it a workaround - but it's simple.

Add the CssClass property to your Menu Control's declaration like so:

<asp:Menu ID="NavigationMenu" DataSourceID="NavigationSiteMapDataSource"
        CssClass="SomeMenuClass"
        StaticMenuStyle-CssClass="StaticMenuStyle"
        StaticMenuItemStyle-CssClass="StaticMenuItemStyle"
        Orientation="Horizontal" 
        MaximumDynamicDisplayLevels="0" 
        runat="server">
</asp:Menu>

Just rip out the StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass attributes as they simply don't do jack.

Now create the "SomeMenuClass", doesn't matter what you put in it. It should look something like this:

.SomeMenuClass
{
    color:Green;
}

Next add the following two CSS Classes:

For "Hover" Styling add:

.SomeMenuClass a.static.highlighted
{
    color:Red !important;
}

For "Selected" Styling add:

.SomeMenuClass a.static.selected
{
    color:Blue !important;
}

There, that's it. You're done. Hope this saves some of you the frustration I went through. BTW: You mentioned:

I seem to be the first one to ever report on what seems to be a bug.

You also seemed to think it was a new .NET 4.0 bug. I found this: http://www.velocityreviews.com/forums/t649530-problem-with-staticselectedstyle-and-statichoverstyle.html posted back in 2008 regarding Asp.Net 2.0 . How are we the only 3 people on the planet complaining about this?

How I found the workaround (study the HTML output):

Here is the HTML output when I set StaticHoverStyle-BackColor="Red":

#NavigationMenu a.static.highlighted
{
    background-color:Red;
}

This is the HTML output when setting StaticSelectedStyle-BackColor="Blue":

#NavigationMenu a.static.selected
{
    background-color:Blue;
    text-decoration:none;
}

Therefore, the logical way to override this markup was to create classes for SomeMenuClass a.static.highlighted and SomeMenuClass a.static.selected

Special Notes:

You MUST also use "!important" on ALL the settings in these classes because the HTML output uses "#NavigationMenu", and that means any styles Asp.Net decides to throw in there for you will have inheritance priority over any other styles for the Menu Control with the ID "NavigationMenu". One thing I struggled with was padding, till I figured out Asp.Net was using "#NavigationMenu" to set the left and right padding to 15em. I tacked on "!important" to my SomeMenuClass styles and it worked.
