same problem with me. This is not a solution but a workaround, which worked for me: Buildpath->Configure buildpath->Libraries-> Here remove the JRE system library pointing to JRE8 and add JRE system library for JRE7.

If you need to get the tab index from outside the context of a tabs event, use this:

function getSelectedTabIndex() { 
    return $("#TabList").tabs('option', 'selected');
}

Update: From version 1.9 'selected' is changed to 'active'

$("#TabList").tabs('option', 'active')

With little php is very easy.

HTML part:

<input type="text" name="some_name">

JavaScript

<script type="text/javascript">
    some_variable = "<?php echo $_POST['some_name']?>";
</script>

What finally worked for me is similar to what @????DJ suggested, but the tabBackground should be in the layout file and not inside the style, so it looks like:

res/layout/somefile.xml:

<android.support.design.widget.TabLayout
    ....
    app:tabBackground="@drawable/tab_color_selector"
    ...
    />

and the selector res/drawable/tab_color_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/tab_background_selected" android:state_selected="true"/>
    <item android:drawable="@color/tab_background_unselected"/>
</selector>

You can use replace_entities from w3lib.html library

In [202]: from w3lib.html import replace_entities

In [203]: replace_entities("£682m")
Out[203]: u'\xa3682m'

In [204]: print replace_entities("£682m")
£682m

The answers did help, but I think a full implementation of this will help a lot of people.

I very often use regex to extract data from files I just used that to replace the literal quote \" with // nothing :-)

cat file.csv | egrep '^\"([0-9]{1,3}\.[0-9]{1,3}\.)' | sed  s/\"//g  | cut -d, -f1 > list.txt

To initialize an array filled with zeros, you can use:

> Array.fill[Byte](5)(0)
Array(0, 0, 0, 0, 0)

This is equivalent to Java's new byte[5].

After comparing timestamp with the one from PHP, none of the above seems correct for my timezone. The code below gave me same result as PHP which is most important for the project I am doing.

function getTimeStamp(input) {_x000D_
    var parts = input.trim().split(' ');_x000D_
    var date = parts[0].split('-');_x000D_
 var time = (parts[1] ? parts[1] : '00:00:00').split(':');_x000D_
_x000D_
 // NOTE:: Month: 0 = January - 11 = December._x000D_
 var d = new Date(date[0],date[1]-1,date[2],time[0],time[1],time[2]);_x000D_
 return d.getTime() / 1000;_x000D_
}_x000D_
_x000D_
// USAGE::_x000D_
var start = getTimeStamp('2017-08-10');_x000D_
var end = getTimeStamp('2017-08-10 23:59:59');_x000D_
_x000D_
console.log(start + ' - ' + end);

I am using this on NodeJS, and we have timezone 'Australia/Sydney'. So, I had to add this on .env file:

TZ = 'Australia/Sydney'

Above is equivalent to:

process.env.TZ = 'Australia/Sydney'

Some "front ends", with the "Use Booleans" option enabled, will treat all TINYINT(1) columns as Boolean, and vice versa.

This allows you to, in the application, use TRUE and FALSE rather than 1 and 0.

This doesn't affect the database at all, since it's implemented in the application.

There is not really a BOOLEAN type in MySQL. BOOLEAN is just a synonym for TINYINT(1), and TRUE and FALSE are synonyms for 1 and 0.

If the conversion is done in the compiler, there will be no difference in performance in the application. Otherwise, the difference still won't be noticeable.

You should use whichever method allows you to code more efficiently, though not using the feature may reduce dependency on that particular "front end" vendor.

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.

WMI is the way to do this.

Get-WmiObject -Query "Select StartMode From Win32_Service Where Name='winmgmt'"

Or

Get-WmiObject -Class Win32_Service -Property StartMode -Filter "Name='Winmgmt'"

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html

Set the Maximise property to False.

I've never seen the -u parameter. But if you want to use an "@", how about stating it as "\@"?

That way it should be interpreted as you intend. You know something like

ftp -u user\@[email protected]

instead of

listItems.add("New Item");
adapter.notifyDataSetChanged();

you can directly call

adapter.add("New Item");

The above answer is good, but if you need a version that can operate along different axes, here's a working implementation.

def entropy(A, axis=None):
    """Computes the Shannon entropy of the elements of A. Assumes A is 
    an array-like of nonnegative ints whose max value is approximately 
    the number of unique values present.

    >>> a = [0, 1]
    >>> entropy(a)
    1.0
    >>> A = np.c_[a, a]
    >>> entropy(A)
    1.0
    >>> A                   # doctest: +NORMALIZE_WHITESPACE
    array([[0, 0], [1, 1]])
    >>> entropy(A, axis=0)  # doctest: +NORMALIZE_WHITESPACE
    array([ 1., 1.])
    >>> entropy(A, axis=1)  # doctest: +NORMALIZE_WHITESPACE
    array([[ 0.], [ 0.]])
    >>> entropy([0, 0, 0])
    0.0
    >>> entropy([])
    0.0
    >>> entropy([5])
    0.0
    """
    if A is None or len(A) < 2:
        return 0.

    A = np.asarray(A)

    if axis is None:
        A = A.flatten()
        counts = np.bincount(A) # needs small, non-negative ints
        counts = counts[counts > 0]
        if len(counts) == 1:
            return 0. # avoid returning -0.0 to prevent weird doctests
        probs = counts / float(A.size)
        return -np.sum(probs * np.log2(probs))
    elif axis == 0:
        entropies = map(lambda col: entropy(col), A.T)
        return np.array(entropies)
    elif axis == 1:
        entropies = map(lambda row: entropy(row), A)
        return np.array(entropies).reshape((-1, 1))
    else:
        raise ValueError("unsupported axis: {}".format(axis))

Make sure you specify pass header=None and add usecols=[3,6] for the 4th and 7th columns.

My recommendation is to solve problems that you're interested in, writing code that might be useful to you.

Java is a huge box. It's got a lot of computer science inside: graphics, scientific computing, relational databases, user interfaces for desktop and web, messaging and queuing, multi-threading, security, and more. Each area has their own "beginner problem". Which one do you mean?

How do you define "beginner problem"? Maybe you're having trouble because you aren't narrowing your search enough.

If your imagination is lacking, your best bet is to Google something like "java beginner practice problems" and investigate what you get back.

Or start with Sun's on-line Java tutorial and work you way all the way through it. You'll know a fair amount about Java when you're done.

Many answers (including the original of this one) don't address the letter- and number-count requirements of the OP. Below are two solutions: general (no min letters/numbers), and with rules.

General:

I believe this is better general solution than the above, because:

• it's more secure than accepted/highest-voted answer, and also more versatile, because it supports any char set in a case-sensitive manner
• it's more concise than other answers (for general solution, 3 lines max; can be one-liner)
• it uses only native Javascript- no installation or other libs required

Note that

• for this to work on IE, the Array.fill() prototype must be polyfilled
• if available, better to use window.crypto.getRandomValues() instead of Math.random() (thanks @BenjaminH for pointing out)

Three-liner:

var pwdChars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
var pwdLen = 10;
var randPassword = Array(pwdLen).fill(pwdChars).map(function(x) { return x[Math.floor(Math.random() * x.length)] }).join('');

Or, as one-liner:

var randPassword = Array(10).fill("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz").map(function(x) { return x[Math.floor(Math.random() * x.length)] }).join('');

With Letter / Number Rules

Now, a variation on the above. This will generate three random strings from the given charsets (letter, number, either) and then scramble the result.

Please note the below uses sort() for illustrative purposes only. For production use, replace the below sort() function with a shuffle function such as Durstenfeld.

First, as a function:

function randPassword(letters, numbers, either) {
  var chars = [
   "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz", // letters
   "0123456789", // numbers
   "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" // either
  ];

  return [letters, numbers, either].map(function(len, i) {
    return Array(len).fill(chars[i]).map(function(x) {
      return x[Math.floor(Math.random() * x.length)];
    }).join('');
  }).concat().join('').split('').sort(function(){
    return 0.5-Math.random();
  }).join('')
}

// invoke like so: randPassword(5,3,2);

Same thing, as a 2-liner (admittedly, very long and ugly lines-- and won't be a 1-liner if you use a proper shuffle function. Not recommended but sometimes it's fun anyway) :

var chars = ["ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz","0123456789", "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"];
var randPwd = [5,3,2].map(function(len, i) { return Array(len).fill(chars[i]).map(function(x) { return x[Math.floor(Math.random() * x.length)] }).join('') }).concat().join('').split('').sort(function(){return 0.5-Math.random()}).join('');

Actually just adding margin-bottom: -20px; to the tag class fixed it right up.

http://jsfiddle.net/dChUR/7/

Being block elements, div's naturally have defined borders that they try not to violate. To get them to layer for images, which have no content beside the image because they have no closing tag, you just have to force them to do what they do not want to do, like violate their natural boundaries.

.container {
  border: 1px solid #DDDDDD;
  width: 200px;
  height: 200px;
  }
.tag {
  float: left;
  position: relative;
  left: 0px;
  top: 0px;
  background-color: green;
  z-index: 1000;
  margin-bottom: -20px;
  }

Another toue to take would be to create div's using an image as the background, and then place content where ever you like.

<div id="imgContainer" style="
         background-image: url("foo.jpg"); 
         background-repeat: no-repeat; 
         background-size: cover; 
         -webkit-background-size: cover; 
         -mox-background-size: cover; 
         -o-background-size: cover;">
  <div id="theTag">BLAH BLAH BLAH</div>
</div>

You'll want to use either JavaScript or a server-side language like PHP, ASP...etc

(supposedly can be done with HTML <embed> tag, which makes sense, but I haven't used, since PHP...etc is so simple/common)

Javascript can work: Here's a link to someone doing something similar via javascript on stackoverflow: How do I load the contents of a text file into a javascript variable?

PHP (as example of server-side language) is the easiest way to go though:

<div><p><?php include('myFile.txt'); ?></p></div>

To use this (if you're unfamiliar with PHP), you can:

1) check if you have php on your server

2) change the file extension of your .html file to .php

3) paste the code from my PHP example somewhere in the body of your newly-renamed PHP file

did the same here needed to show "success" twice response is data from PHP

 String res=response.toString().trim;

                            Toast.makeText(sign_in.this,res,Toast.LENGTH_SHORT).show();
    if ( res.compareTo("success")==0){
    Toast.makeText(this,res,Toast.LENGTH_SHORT).show();
    }

as @fabrizio-valencia said use lower case. in windows if you export mysql database (phpmyadmin) the tables name will converted to lower case and this lead to all sort of problems. see Are table names in MySQL case sensitive?

Under the Tools menu in Visual Studio 2008 (or 2005 if you have the right WCF stuff installed) there is an options called 'WCF Service Configuration Editor'.

From there you can change the binding options for both the client and the services, one of these options will be for time-outs.

The following works for me in case you need last two tags (for example, in order to generate change log between current tag and the previous tag). I've tested it only in situation where the latest tag was the HEAD.

PreviousAndCurrentGitTag=`git describe --tags \`git rev-list --tags --abbrev=0 --max-count=2\` --abbrev=0`
PreviousGitTag=`echo $PreviousAndCurrentGitTag | cut -f 2 -d ' '`
CurrentGitTag=`echo $PreviousAndCurrentGitTag | cut -f 1 -d ' '`

GitLog=`git log ${PreviousGitTag}..${CurrentGitTag} --pretty=oneline | sed "s_.\{41\}\(.*\)_; \1_"`

It suits my needs, but as I'm no git wizard, I'm sure it could be further improved. I also suspect it will break in case the commit history moves forward. I'm just sharing in case it helps someone.

The KB article linked in Joe's post is great for determining which service packs have been installed for any version. Along those same lines, this KB article maps version numbers to specific hotfixes and cumulative updates, but it only applies to SQL05 SP2 and up.

Check the schemes menu at the top of the Xcode project window. Look at the destination you're trying to run in. If you run in the simulator, you don't need to sign your project.

If you run in a device, you need to attach the actual device. It must not say "generic device".

In case anybody stumbles upon this question who cannot reload their webserver (long running console command like a queue runner) or needs to reload their .env file mid-request, i found a way to properly reload .env variables in laravel 5.

use Dotenv;
use InvalidArgumentException;

try {
    Dotenv::makeMutable();
    Dotenv::load(app()->environmentPath(), app()->environmentFile());
    Dotenv::makeImmutable();
} catch (InvalidArgumentException $e) {
    //
}

Always use heading tags for headings. The clue is in the name :)

If you don’t want them to be bold, change their style with CSS. For example:

HTML:

<h3 class="list-heading">heading</h3>

<ul> 
    <li>list item </li>
    <li>list item </li>
    <li>list item </li>
</ul>

CSS

.list-heading {
    font-weight: normal;
}

In HTML5, you can associate the heading and the list more clearly by using the <section> element. (<section> doesn’t work properly in IE 8 and earlier without some JavaScript though.)

<section>
    <h1>heading</h1>

    <ul>
        <li>list item </li>
        <li>list item </li>
        <li>list item </li>
    </ul>
</section>

You could do something similar in HTML 4:

<div class="list-with-heading">
    <h3>Heading</h3>

    <ul>
        <li>list item </li>
        <li>list item </li>
        <li>list item </li>
    </ul>
</div>

Then style thus:

.list-with-heading h3 {

}

The syntax has changed in that print is now a function. This means that the % formatting needs to be done inside the parenthesis:¹

print("%d. %s appears %d times." % (i, key, wordBank[key]))

However, since you are using Python 3.x., you should actually be using the newer str.format method:

print("{}. {} appears {} times.".format(i, key, wordBank[key]))

Though % formatting is not officially deprecated (yet), it is discouraged in favor of str.format and will most likely be removed from the language in a coming version (Python 4 maybe?).

_{¹Just a minor note: %d is the format specifier for integers, not %s.}

I have used the following code. It works fine for me.

$('a').bind('click', function(e) {
  e.stopPropagation();
});

First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.

If not you have some compilation errors in your java classes.

Simple Steps:

1. Click File > Project Structure

2. Click Dependencies > Find and Click org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.21 (or whatever your current version is)

3. Under Details > update section, click [update variable][update dependencies]

4. Click Ok

The original newbie approaches that I offered were (opt1):

$qb->where("e.fecha > '" . $monday->format('Y-m-d') . "'");
$qb->andWhere("e.fecha < '" . $sunday->format('Y-m-d') . "'");

And (opt2):

$qb->add('where', "e.fecha between '2012-01-01' and '2012-10-10'");

That was quick and easy and got the original poster going immediately.

Hence the accepted answer.

As per comments, it is the wrong answer, but it's an easy mistake to make, so I'm leaving it here as a "what not to do!"

It is very simple:

try { 
  // Your code here.
} catch (IllegalArgumentException | SecurityException | IllegalAccessException |
            NoSuchFieldException e) { 
  // Handle exception here.
}

I think, that will be good solution: /\S\w*/

When you go to a website, your browser sends a request to the web server including a lot of information. This information might look something like this:

GET /questions/18070154/get-operating-system-info-with-php HTTP/1.1  
Host: stackoverflow.com  
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36

Accept-Language: en-us,en;q=0.5  
Accept-Encoding: gzip,deflate,sdch

Keep-Alive: 300  
Connection: keep-alive  
Cookie: <cookie data removed> 
Pragma: no-cache  
Cache-Control: no-cache

These information are all used by the web server to determine how to handle the request; the preferred language and whether compression is allowed.

In PHP, all this information is stored in the $_SERVER array. To see what you're sending to a web server, create a new PHP file and print out everything from the array.

<pre><?php print_r($_SERVER); ?></pre>

This will give you a nice representation of everything that's being sent to the server, from where you can extract the desired information, e.g. $_SERVER['HTTP_USER_AGENT'] to get the operating system and browser.

where tableName - is an index table name and indexName - is an index name

This may be a separate gitk window running to see some git history.

Just close that window to fix that problem.

The solution for me was to remove white space in one of my helper files. The error listed two pages involved, a CI session file and one of my custom helpers.

Bundle extras = getIntent().getExtras();
Set<String> ks = extras.keySet();
Iterator<String> iterator = ks.iterator();
while (iterator.hasNext()) {
    Log.d("KEY", iterator.next());
}

From what I can see, none of the above can handle normal parameters and array parameters. Here's one that does.

function removeURLParameter(param, url) {
    url = decodeURI(url).split("?");
    path = url.length == 1 ? "" : url[1];
    path = path.replace(new RegExp("&?"+param+"\\[\\d*\\]=[\\w]+", "g"), "");
    path = path.replace(new RegExp("&?"+param+"=[\\w]+", "g"), "");
    path = path.replace(/^&/, "");
    return url[0] + (path.length
        ? "?" + path
        : "");
}

function addURLParameter(param, val, url) {
    if(typeof val === "object") {
        // recursively add in array structure
        if(val.length) {
            return addURLParameter(
                param + "[]",
                val.splice(-1, 1)[0],
                addURLParameter(param, val, url)
            )
        } else {
            return url;
        }
    } else {
        url = decodeURI(url).split("?");
        path = url.length == 1 ? "" : url[1];
        path += path.length
            ? "&"
            : "";
        path += decodeURI(param + "=" + val);
        return url[0] + "?" + path;
    }
}

How to use it:

url = location.href;
    -> http://example.com/?tags[]=single&tags[]=promo&sold=1

url = removeURLParameter("sold", url)
    -> http://example.com/?tags[]=single&tags[]=promo

url = removeURLParameter("tags", url)
    -> http://example.com/

url = addURLParameter("tags", ["single", "promo"], url)
    -> http://example.com/?tags[]=single&tags[]=promo

url = addURLParameter("sold", 1, url)
    -> http://example.com/?tags[]=single&tags[]=promo&sold=1

Of course, to update a parameter, just remove then add. Feel free to make a dummy function for it.

The default char is the character with an int value of 0 (zero).

char NULLCHAR = (char) 0;

char NULLCHAR = '\0';

For 4 digit representation:

<?php echo date('Y'); ?>

2 digit representation:

<?php echo date('y'); ?>

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

If you want to show the name of processes and kill them by the command of the kill, I recommended using this script to kill all python3 running process and set your ram memory free :

ps auxww | grep 'python3' | awk '{print $2}' | xargs kill -9

A way to get this can be print multiple end of lines ("\n") and simulate the clear screen. At the end clear, at most in the unix shell, not removes the previous content, only moves it up and if you make scroll down can see the previous content.

Here is a sample code:

for (int i = 0; i < 50; ++i) System.out.println();

SELECT Q.FK
      ,ISNULL(T1.Field1, T2.Field2) AS Field
FROM (SELECT FK FROM Table1
        UNION
      SELECT FK FROM Table2) AS Q
LEFT JOIN Table1 AS T1 ON T1.FK = Q.FK
LEFT JOIN Table2 AS T2 ON T2.FK = Q.FK

If there is one table, write Table1 instead of Table2

It looks like the documentation is just using readStream() to mean:

Ok, we've shown you how to get the InputStream, now your code goes in readStream()

So you should either write your own readStream() method which does whatever you wanted to do with the data in the first place.

Google introduced new API called PercentRelativeLayout

Add compile dependency like

compile 'com.android.support:percent:22.2.0'

in that PercentRelativeLayout is what we can do percentagewise layout

For C++, there are various type-safe enum techniques available, and some of those (such as the proposed-but-never-submitted Boost.Enum) include support for getting the size of a enum.

The simplest approach, which works in C as well as C++, is to adopt a convention of declaring a ...MAX value for each of your enum types:

enum Folders { FA, FB, FC, Folders_MAX = FC };
ContainerClass *m_containers[Folders_MAX + 1];
....
m_containers[FA] = ...; // etc.

Edit: Regarding { FA, FB, FC, Folders_MAX = FC} versus {FA, FB, FC, Folders_MAX]: I prefer setting the ...MAX value to the last legal value of the enum for a few reasons:

1. The constant's name is technically more accurate (since Folders_MAX gives the maximum possible enum value).
2. Personally, I feel like Folders_MAX = FC stands out from other entries out a bit more (making it a bit harder to accidentally add enum values without updating the max value, a problem Martin York referenced).
3. GCC includes helpful warnings like "enumeration value not included in switch" for code such as the following. Letting Folders_MAX == FC + 1 breaks those warnings, since you end up with a bunch of ...MAX enumeration values that should never be included in switch.

switch (folder) 
{
  case FA: ...;
  case FB: ...;
  // Oops, forgot FC!
}

I don't know how cryptographically sound this is, but it's more readable and concise than the more intricate solutions by far (imo), and it should be more "random" than System.Random-based solutions.

return alphabet
    .OrderBy(c => Guid.NewGuid())
    .Take(strLength)
    .Aggregate(
        new StringBuilder(),
        (builder, c) => builder.Append(c))
    .ToString();

I can't decide if I think this version or the next one is "prettier", but they give the exact same results:

return new string(alphabet
    .OrderBy(o => Guid.NewGuid())
    .Take(strLength)
    .ToArray());

Granted, it isn't optimized for speed, so if it's mission critical to generate millions of random strings every second, try another one!

NOTE: This solution doesn't allow for repetitions of symbols in the alphabet, and the alphabet MUST be of equal or greater size than the output string, making this approach less desirable in some circumstances, it all depends on your use-case.

Read these answered questions to understand the difference between Cygwin and MinGW.

Question #1: I want to create an application that I write source code once, compile it once and run it in any platforms (e.g. Windows, Linux and Mac OS X…).

Answer #1: Write your source code in JAVA. Compile the source code once and run it anywhere.

Question #2: I want to create an application that I write source code once but there is no problem that I compile the source code for any platforms separately (e.g. Windows, Linux and Mac OS X …).

Answer #2: Write your source code in C or C++. Use standard header files only. Use a suitable compiler for any platform (e.g. Visual Studio for Windows, GCC for Linux and XCode for Mac). Note that you should not use any advanced programming features to compile your source code in all platforms successfully. If you use none C or C++ standard classes or functions, your source code does not compile in other platforms.

Question #3: In answer of question #2, it is difficult using different compiler for each platform, is there any cross platform compiler?

Answer #3: Yes, Use GCC compiler. It is a cross platform compiler. To compile your source code in Windows use MinGW that provides GCC compiler for Windows and compiles your source code to native Windows program. Do not use any advanced programming features (like Windows API) to compile your source code in all platforms successfully. If you use Windows API functions, your source code does not compile in other platforms.

Question #4: C or C++ standard header files do not provide any advanced programming features like multi-threading. What can I do?

Answer #4: You should use POSIX (Portable Operating System Interface [for UNIX]) standard. It provides many advanced programming features and tools. Many operating systems fully or partly POSIX compatible (like Mac OS X, Solaris, BSD/OS and ...). Some operating systems while not officially certified as POSIX compatible, conform in large part (like Linux, FreeBSD, OpenSolaris and ...). Cygwin provides a largely POSIX-compliant development and run-time environment for Microsoft Windows.

Thus:

To use advantage of GCC cross platform compiler in Windows, use MinGW.

To use advantage of POSIX standard advanced programming features and tools in Windows, use Cygwin.

Try something like this:

<div id="LoadingImage" style="display: none">
  <img src="" />
</div>

<script>
  function ajaxCall(){
    $("#LoadingImage").show();
      $.ajax({ 
        type: "GET", 
        url: surl, 
        dataType: "jsonp", 
        cache : false, 
        jsonp : "onJSONPLoad", 
        jsonpCallback: "newarticlescallback", 
        crossDomain: "true", 
        success: function(response) { 
          $("#LoadingImage").hide();
          alert("Success"); 
        }, 
        error: function (xhr, status) {  
          $("#LoadingImage").hide();
          alert('Unknown error ' + status); 
        }    
      });  
    }
</script>

InnerText property html-encodes the content, turning <p> to <p>, etc. If you want to insert HTML tags you need to use InnerHTML.

Your file .idea/workspace.xml is not under git version control. You have either not added it yet (check git status/Untracked files) or ignored it (using .gitignore or .git/info/exclude files)

You can verify it using following git command, that lists all ignored files:

git ls-files --others -i --exclude-standard

Building on verified answer, for me this worked best:

ab = pd.concat({k: pd.DataFrame(v).T for k, v in data.items()}, axis=0)
ab.T

Use geom_text , with aes label. You can play with hjust, vjust to adjust text position.

ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +geom_text(aes(label=Name),hjust=0, vjust=0)

EDIT: Label only values above a certain threshold:

  ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +
  geom_text(aes(label=ifelse(PTS>24,as.character(Name),'')),hjust=0,vjust=0)

go to phpmyadmin and drop the database that you created for laravel then create it again then go to cmd(if use windows) root project and type php artisan migrate

Instead of comparison methods you may want to just define several types of "Comparator" subclasses inside the Person class. That way you can pass them into standard Collections sorting methods.

I use this approach to create a custom switch using a RadioGroup and RadioButton;

The accepted answer only shows files in the current directory's tree. To show all of the tracked files that have been committed (on the current branch), use

git ls-tree --full-tree --name-only -r HEAD

• --full-tree makes the command run as if you were in the repo's root directory.
• -r recurses into subdirectories. Combined with --full-tree, this gives you all committed, tracked files.
• --name-only removes SHA / permission info for when you just want the file paths.
• HEAD specifies which branch you want the list of tracked, committed files for. You could change this to master or any other branch name, but HEAD is the commit you have checked out right now.

This is the method from the accepted answer to the ~duplicate question https://stackoverflow.com/a/8533413/4880003.

1. Add a property to your controller (or base controller) called MainLayoutViewModel (or whatever) with whatever type you would like to use.
2. In the constructor of your controller (or base controller), instantiate the type and set it to the property.
3. Set it to the ViewData field (or ViewBag)
4. In the Layout page, cast that property to your type.

Example: Controller:

public class MyController : Controller
{
    public MainLayoutViewModel MainLayoutViewModel { get; set; }

    public MyController()
    {
        this.MainLayoutViewModel = new MainLayoutViewModel();//has property PageTitle
        this.MainLayoutViewModel.PageTitle = "my title";

        this.ViewData["MainLayoutViewModel"] = this.MainLayoutViewModel;
    }

}

Example top of Layout Page

@{
var viewModel = (MainLayoutViewModel)ViewBag.MainLayoutViewModel;
}

Now you can reference the variable 'viewModel' in your layout page with full access to the typed object.

I like this approach because it is the controller that controls the layout, while the individual page viewmodels remain layout agnostic.

Notes for MVC Core

public class MyActionFilter: Attribute, IActionFilter
    {
        public void OnActionExecuted(ActionExecutedContext context)
        {
        }

        public void OnActionExecuting(ActionExecutingContext context)
        {
            var myController= context.Controller as MyController;

            if (myController!= null)
            {
                myController.Layout = new MainLayoutViewModel
                {

                };

                myController.ViewBag.MainLayoutViewModel= myController.Layout;
            }
        }
    }

(months later) it's easy to add your own cache around re.match, or anything else for that matter --

Just add two attributes to the parent view of editText.

android:focusable="true"
android:focusableInTouchMode="true"

So the issue is actually that you are not waiting for the init to complete. This will cause random results. Here is what I use.

window.fbAsyncInit = function () {
    FB.init({ appId: 'your-app-id', cookie: true, xfbml: true, oauth: true });

    // *** here is my code ***
    if (typeof facebookInit == 'function') {
        facebookInit();
    }
};

(function(d){
    var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
    js = d.createElement('script'); js.id = id; js.async = true;
    js.src = "//connect.facebook.net/en_US/all.js";
    d.getElementsByTagName('head')[0].appendChild(js);
}(document));

This will ensure that once everything is loaded, the function facebookInit is available and executed. That way you don't have to duplicate the init code every time you want to use it.

function facebookInit() {
   // do what you would like here
}

<button class="btn btn-primary btn-lg" data-backdrop="static" data-keyboard="false" data-target="#myModal" data-toggle="modal">

You may use any standard encoding of your specific usage and input.

utf-8 is the default.

iso8859-1 is also popular for Western Europe.

e.g: bytes_obj.decode('iso8859-1')

see: docs

Not yet, but the New NIO (JSR 203) will have support for these common operations.

In the meantime, there are a few things to keep in mind.

File.renameTo generally works only on the same file system volume. I think of this as the equivalent to a "mv" command. Use it if you can, but for general copy and move support, you'll need to have a fallback.

When a rename doesn't work you will need to actually copy the file (deleting the original with File.delete if it's a "move" operation). To do this with the greatest efficiency, use the FileChannel.transferTo or FileChannel.transferFrom methods. The implementation is platform specific, but in general, when copying from one file to another, implementations avoid transporting data back and forth between kernel and user space, yielding a big boost in efficiency.

Or, you can ignore the error:

declare
    column_exists exception;
    pragma exception_init (column_exists , -01430);
begin
    execute immediate 'ALTER TABLE db.tablename ADD columnname NVARCHAR2(30)';
    exception when column_exists then null;
end;
/

That's because the result of adding two Int16 is an Int32. Check the "conversions" paragraph here: http://msdn.microsoft.com/en-us/library/ybs77ex4%28v=vs.71%29.aspx

VS 2015 changes this. It added a .vs folder to my web project and the applicationhost.config was in there. I made the changes suggested (window authentication = true, anon=false) and it started delivering a username instead of a blank.

You need to set the flags after the project command in your CMakeLists.txt.

Also, if you're calling include(${QT_USE_FILE}) or add_definitions(${QT_DEFINITIONS}), you should include these set commands after the Qt ones since these would append further flags. If that is the case, you maybe just want to append your flags to the Qt ones, so change to e.g.

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O0 -ggdb")

I found the answer to the Bad Request 400 problem.

It was the default server binding setting. You would need to add to server and client default setting.

binding name="" openTimeout="00:10:00" closeTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">

If you are using the IN operator, the SQL engine will scan all records fetched from the inner query. On the other hand if we are using EXISTS, the SQL engine will stop the scanning process as soon as it found a match.

This should give you all the details of the existing locks.

DECLARE @tblVariable TABLE(SPID INT, Status VARCHAR(200), [Login] VARCHAR(200), HostName VARCHAR(200), 
    BlkBy VARCHAR(200), DBName VARCHAR(200), Command VARCHAR(200), CPUTime INT, 
    DiskIO INT, LastBatch VARCHAR(200), ProgramName VARCHAR(200), _SPID INT, 
    RequestID INT)

INSERT INTO @tblVariable
EXEC Master.dbo.sp_who2

SELECT v.*, t.TEXT 
FROM @tblVariable v
INNER JOIN sys.sysprocesses sp ON sp.spid = v.SPID
CROSS APPLY sys.dm_exec_sql_text(sp.sql_handle) AS t
ORDER BY BlkBy DESC, CPUTime DESC

You can then kill, with caution, the SPID that blocks your table.

kill 104 -- Your SPID

\?(.*)

You want the content of the first capture group.

Great solution, had one small issue with conflicts, If anyone else has conflict from other js library simply enable no conflict like so.

var $j = jQuery.noConflict();$j('img').bind('dragstart', function(event) { event.preventDefault(); });

Hope this helps someone out.

I hope these simple steps will help:

20 % 3 = 2 

1. 20 / 3 = 6; do not include the .6667 – just ignore it
2. 3 * 6 = 18
3. 20 - 18 = 2, which is the remainder of the modulo

As for me, chaining set methods is the cleanest way

const params = new HttpParams()
.set('aaa', '111')
.set('bbb', "222");

Here you can create schema using StructType in scala and pass the Empty RDD so you will able to create empty table. Following code is for the same.

import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
import org.apache.spark.sql._
import org.apache.spark.sql.Row
import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.types.StructType
import org.apache.spark.sql.types.StructField
import org.apache.spark.sql.types.IntegerType
import org.apache.spark.sql.types.BooleanType
import org.apache.spark.sql.types.LongType
import org.apache.spark.sql.types.StringType



//import org.apache.hadoop.hive.serde2.objectinspector.StructField

object EmptyTable extends App {
  val conf = new SparkConf;
  val sc = new SparkContext(conf)
  //create sparksession object
  val sparkSession = SparkSession.builder().enableHiveSupport().getOrCreate()

  //Created schema for three columns 
   val schema = StructType(
    StructField("Emp_ID", LongType, true) ::
      StructField("Emp_Name", StringType, false) ::
      StructField("Emp_Salary", LongType, false) :: Nil)

      //Created Empty RDD 

  var dataRDD = sc.emptyRDD[Row]

  //pass rdd and schema to create dataframe
  val newDFSchema = sparkSession.createDataFrame(dataRDD, schema)

  newDFSchema.createOrReplaceTempView("tempSchema")

  sparkSession.sql("create table Finaltable AS select * from tempSchema")

}

For the Platform Independent Users or Windows users, what you can do is:

import runtime:

import (
    "runtime"
    "strings"
)

and then trim the string like this:

if runtime.GOOS == "windows" {
  input = strings.TrimRight(input, "\r\n")
} else {
  input = strings.TrimRight(input, "\n")
}

now you can compare it like that:

if strings.Compare(input, "a") == 0 {
  //....yourCode
}

This is a better approach when you're making use of STDIN on multiple platforms.

Explanation

This happens because on windows lines end with "\r\n" which is known as CRLF, but on UNIX lines end with "\n" which is known as LF and that's why we trim "\n" on unix based operating systems while we trim "\r\n" on windows.

You can update gem to any specific version like this,

gem update --system 'version'

gem update --system '2.3.0'

In my case the IIS did not have the necessary permissions to access the relevant ASPX path.

I gave the IIS user permissions to the relevant directory and all was well.

var is a "contextual keyword" in C# meaning you can only use it as a local variable implicitly in the context of the same class that you are using the variable. If you try to use it in a class that you call from "Main" or some other exterior class, or an interface for example you will get the error CS0825 < https://docs.microsoft.com/en-us/dotnet/csharp/misc/cs0825 >

See the remarks about when you can and can't use it in the documentation here: < https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/implicitly-typed-local-variables#remarks >

Basically, you should only use this when you are declaring a variable with an implicit value such as "var myValue = "This is the value"; This saves a little time in comparison to saying "string" for example but IMHO not much time is saved and places a constraint on the scalability of your project.

The previous answers show 3 approaches

1. By creating a new data frame
2. By using "cbind"
3. By adding column "a", and sort data frame by columns using column names or indexes

Let me show #4 approach "By using "cbind" and "rename" that works for my case

1. Create data frame

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))

2. Get values for "new" column

new_column = c(0, 0, 0)

3. Combine "new" column with existed

df <- cbind(new_column, df)

4. Rename "new" column name

colnames(df)[1] <- "a"

The question is actually asking for a New array, so I believe a better solution would be to combine Abdennour TOUMI's answer with a clone function:

function clone(obj) {_x000D_
  if (null == obj || "object" != typeof obj) return obj;_x000D_
  const copy = obj.constructor();_x000D_
  for (const attr in obj) {_x000D_
    if (obj.hasOwnProperty(attr)) copy[attr] = obj[attr];_x000D_
  }_x000D_
  return copy;_x000D_
}_x000D_
_x000D_
// With the `clone()` function, you can now do the following:_x000D_
_x000D_
Array.prototype.subarray = function(start, end) {_x000D_
  if (!end) {_x000D_
    end = this.length;_x000D_
  } _x000D_
  const newArray = clone(this);_x000D_
  return newArray.slice(start, end);_x000D_
};_x000D_
_x000D_
// Without a copy you will lose your original array._x000D_
_x000D_
// **Example:**_x000D_
_x000D_
const array = [1, 2, 3, 4, 5];_x000D_
console.log(array.subarray(2)); // print the subarray [3, 4, 5, subarray: function]_x000D_
_x000D_
console.log(array); // print the original array [1, 2, 3, 4, 5, subarray: function]

Executing commands in a background shell

Just add & to the end of the command, e.g:

bash -c some_command && another_command &

There is a better solution now: Vertical align anything with just 3 lines of CSS

There is a simpler answer to this than the answer given by the op in the question (the approach is the same):

Define the key in the web.config:

<add key="VersionNumber" value="06032014"/>

Make the call to appsettings directly from the aspx page:

<link href="styles/navigation.css?v=<%=ConfigurationManager.AppSettings["VersionNumber"]%>" rel="stylesheet" type="text/css" />

You could use event delegation on the parent div. Or use the closest method to find the parent of the button.

The easiest of the two is probably the closest.

var id = $("button").closest("div").prop("id");

You need a semicolon after font-family: Arial, Helvetica, sans-serif. This will make your updated code the following:

<!DOCTYPE>
<html>
    <head>
        <title>DIV Font</title>

        <style>
            .my_text
            {
                font-family:    Arial, Helvetica, sans-serif;
                font-size:      40px;
                font-weight:    bold;
            }
        </style>
    </head>

    <body>
        <div class="my_text">some text</div>
    </body>
</html>

app: build.gradle

dependencies {
...
compile 'com.google.firebase:firebase-ads:10.0.1'
...
}

Your Activity:

 AdRequest.Builder builder = new AdRequest.Builder();
        if(BuildConfig.DEBUG){

            String android_id = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
            String deviceId = io.fabric.sdk.android.services.common.CommonUtils.md5(android_id).toUpperCase();
            builder.addTestDevice(deviceId);
        }
        AdRequest adRequest = builder.build();
    adView.loadAd(adRequest);

The following works with a relative path to an image into a subfolder next to the document (currently only tested on a Windows System):

![image info](./pictures/image.png)

Not very clear what your issue is, but it sounds like you want something like this:

    List<string> printer = new List<string>( new [] { "jupiter", "neptune", "pangea", "mercury", "sonic" } );

    if( printer.Exists( p => p.Equals( "jupiter" ) ) )
    {
        ...
    }

My current setup (on MVC3, but I think it still applies) relies on having an ErrorController, so I use:

<system.web>
    <customErrors mode="On" defaultRedirect="~/Error">
      <error redirect="~/Error/NotFound" statusCode="404" />
    </customErrors>
</system.web>

And the controller contains the following:

public class ErrorController : Controller
{
    public ViewResult Index()
    {
        return View("Error");
    }
    public ViewResult NotFound()
    {
        Response.StatusCode = 404;  //you may want to set this to 200
        return View("NotFound");
    }
}

And the views just the way you implement them. I tend to add a bit of logic though, to show the stack trace and error information if the application is in debug mode. So Error.cshtml looks something like this:

@model System.Web.Mvc.HandleErrorInfo
@{
    Layout = "_Layout.cshtml";
    ViewBag.Title = "Error";
}
<div class="list-header clearfix">
    <span>Error</span>
</div>
<div class="list-sfs-holder">
    <div class="alert alert-error">
        An unexpected error has occurred. Please contact the system administrator.
    </div>
    @if (Model != null && HttpContext.Current.IsDebuggingEnabled)
    {
        <div>
            <p>
                <b>Exception:</b> @Model.Exception.Message<br />
                <b>Controller:</b> @Model.ControllerName<br />
                <b>Action:</b> @Model.ActionName
            </p>
            <div style="overflow:scroll">
                <pre>
                    @Model.Exception.StackTrace
                </pre>
            </div>
        </div>
    }
</div>

The override function getParams works fine. You use POST method and you have set the jBody as null. That's why it doesn't work. You could use GET method if you want to send null jBody. I have override the method getParams and it works either with GET method (and null jBody) either with POST method (and jBody != null)

Also there are all the examples here

Several options, by order of most appropriate way:

1. Return an int from the Program.Main method
2. Throw an exception and don't handle it anywhere (use for unexpected error situations)
3. To force termination elsewhere, System.Environment.Exit (not portable! see below)

Edited 9/2013 to improve readability

Returning with a specific exit code: As Servy points out in the comments, you can declare Main with an int return type and return an error code that way. So there really is no need to use Environment.Exit unless you need to terminate with an exit code and can't possibly do it in the Main method. Most probably you can avoid that by throwing an exception, and returning an error code in Main if any unhandled exception propagates there. If the application is multi-threaded you'll probably need even more boilerplate to properly terminate with an exit code so you may be better off just calling Environment.Exit.

Another point against using Evironment.Exit - even when writing multi-threaded applications - is reusability. If you ever want to reuse your code in an environment that makes Environment.Exit irrelevant (such as a library that may be used in a web server), the code will not be portable. The best solution still is, in my opinion, to always use exceptions and/or return values that represent that the method reached some error/finish state. That way, you can always use the same code in any .NET environment, and in any type of application. If you are writing specifically an app that needs to return an exit code or to terminate in a way similar to what Environment.Exit does, you can then go ahead and wrap the thread at the highest level and handle the errors/exceptions as needed.

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

FYI, I needed to update the color of the calendar icon which didn't seem possible with properties like color, fill, etc.

I did eventually figure out that some filter properties will adjust the icon so while i did not end up figuring out how to make it any color, luckily all I needed was to make it so the icon was visible on a dark background so I was able to do the following:

body { background: black; }_x000D_
_x000D_
input[type="date"] { _x000D_
  background: transparent;_x000D_
  color: white;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-calendar-picker-indicator {_x000D_
  filter: invert(100%);_x000D_
}

<body>_x000D_
 <input type="date" />_x000D_
</body>

Hopefully this helps some people as for the most part chrome even directly says this is impossible.

Unless you want to talk to an SMTP server directly via telnet you'd use commandline mailers like blat:

blat -to [email protected] -f [email protected] -s "mail subject" ^
  -server smtp.example.net -body "message text"

or bmail:

bmail -s smtp.example.net -t [email protected] -f [email protected] -h ^
  -a "mail subject" -b "message text"

You could also write your own mailer in VBScript or PowerShell.

You need to have a subquery to get their latest date per user ID.

SELECT  a.*, c.*
FROM users a 
    INNER JOIN payments c
        ON a.id = c.user_ID
    INNER JOIN
    (
        SELECT user_ID, MAX(date) maxDate
        FROM payments
        GROUP BY user_ID
    ) b ON c.user_ID = b.user_ID AND
            c.date = b.maxDate
WHERE a.package = 1

Had the same issue but mine was working for weeks before this. Realised I had changed my password on the server.

Remember to update your password if you've got the option selected 'Run whether user is logged on or not'

Lombok does not support that also indicated by making any @Value annotated class final (as you know by using @NonFinal).

The only workaround I found is to declare all members final yourself and use the @Data annotation instead. Those subclasses need to be annotated by @EqualsAndHashCode and need an explicit all args constructor as Lombok doesn't know how to create one using the all args one of the super class:

@Data
public class A {
    private final int x;
    private final int y;
}

@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
    private final int z;

    public B(int x, int y, int z) {
        super(x, y);
        this.z = z;
    }
}

Especially the constructors of the subclasses make the solution a little untidy for superclasses with many members, sorry.

Or you may do the following

$(this).animate({color:'black'},1000);

But you need to download the color plugin from here.

Download the file and from the same directory run docker build -t nodebb .

This will give you an image on your local machine that's named nodebb that you can launch an container from with docker run -d nodebb (you can change nodebb to your own name).

This will give you the desired result

#!/usr/bin/python

import os

# traverse root directory, and list directories as dirs and files as files
for root, dirs, files in os.walk("."):
    path = root.split(os.sep)
    print((len(path) - 1) * '---', os.path.basename(root))
    for file in files:
        print(len(path) * '---', file)

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

Here is how I solved it for myself. Below is an Entity example with default value for MySQL. However, this also requires the setup of a constructor in your entity, and for you to set the default value there.

Entity\Example:
  type: entity
  table: example
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    label:
      type: string
      columnDefinition: varchar(255) NOT NULL DEFAULT 'default_value' COMMENT 'This is column comment'

I also had to setup connection to 2 datasources from Spring Boot application, and it was not easy - the solution mentioned in the Spring Boot documentation didn't work. After a long digging through the internet I made it work and the main idea was taken from this article and bunch of other places.

The following solution is written in Kotlin and works with Spring Boot 2.1.3 and Hibernate Core 5.3.7. Main issue was that it was not enough just to setup different DataSource configs, but it was also necessary to configure EntityManagerFactory and TransactionManager for both databases.

Here is config for the first (Primary) database:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "firstDbEntityManagerFactory",
    transactionManagerRef = "firstDbTransactionManager",
    basePackages = ["org.path.to.firstDb.domain"]
)
@EnableTransactionManagement
class FirstDbConfig {

    @Bean
    @Primary

        @Qualifier("secondDbDataSource") dataSource: DataSource
    ): LocalContainerEntityManagerFactoryBean {
        return builder
            .dataSource(dataSource)
            .packages(EntityFromSecondDb::class.java)
            .persistenceUnit("secondDb")
            .build()
    }

    @Bean(name = ["secondDbTransactionManager"])
    fun secondDbTransactionManager(
        @Qualifier("secondDbEntityManagerFactory") secondDbEntityManagerFactory: EntityManagerFactory

        return JpaTransactionManager(secondDbEntityManagerFactory)
    }
}

The properties for datasources are like this:

spring.datasource.firstDb.jdbc-url=
spring.datasource.firstDb.username=
spring.datasource.firstDb.password=

spring.datasource.secondDb.jdbc-url=
spring.datasource.secondDb.username=
spring.datasource.secondDb.password=

Issue with properties was that I had to define jdbc-url instead of url because otherwise I had an exception.

p.s. Also you might have different naming schemes in your databases, which was the case for me. Since Hibernate 5 does not support all previous naming schemes, I had to use solution from this answer - maybe it will also help someone as well.

Just want to add gitqlite into the mix of answers here, which is a command-line tool that enables execution of SQL queries on git data, such as SELECT * FROM commits WHERE author_name = 'foo' etc.

Full disclosure, I'm a creator/maintainer of the project!

subprocess.check_output() returns a bytestring.

In Python 3, there's no implicit conversion between unicode (str) objects and bytes objects. If you know the encoding of the output, you can .decode() it to get a string, or you can turn the \n you want to add to bytes with "\n".encode('ascii')

Unit test is usually done for a single functionality implemented in Software module. The scope of testing is entirely within this SW module. Unit test never fulfils the final functional requirements. It comes under whitebox testing methodology..

Whereas Integration test is done to ensure the different SW module implementations. Testing is usually carried out after module level integration is done in SW development.. This test will cover the functional requirements but not enough to ensure system validation.

Update for PHP 7 (thanks shock_gone_wild)

PHP 7 introduces the so called null coalescing operator which simplifies the below statements to:

$var = $var ?? "default";

Before PHP 7

No, there is no special operator or special syntax for this. However, you could use the ternary operator:

$var = isset($var) ? $var : "default";

Or like this:

isset($var) ?: $var = 'default';

Not really an answer to your question as asked, but thought I'd chip in about your general objective.

There already is a method to generate random file names in .NET.

See System.Path.GetTempFileName and GetRandomFileName.

Alternatively, it is a common practice to use a GUID to name random files.

I got this exception too. MY error code is below

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod(requestMethod);
        connection.setRequestProperty("Content-type", "JSON");

I found "Content-type" should not be "JSON",is wrong! I solved this exception by update this line to below

        connection.setRequestProperty("Content-type", "application/json");

you can check up your "Content-type"

Accessing batch parameters can be simple with %1, %2, ... %9 or also %*,
but only if the content is simple.

There is no simple way for complex contents like "&"^&, as it's not possible to access %1 without producing an error.

set  var=%1
set "var=%1"
set  var=%~1
set "var=%~1"

The lines expand to

set  var="&"&
set "var="&"&"
set  var="&"&
set "var="&"&"

And each line fails, as one of the & is outside of the quotes.

It can be solved with reading from a temporary file a remarked version of the parameter.

@echo off
SETLOCAL DisableDelayedExpansion

SETLOCAL
for %%a in (1) do (
    set "prompt="
    echo on
    for %%b in (1) do rem * #%1#
    @echo off
) > param.txt
ENDLOCAL

for /F "delims=" %%L in (param.txt) do (
  set "param1=%%L"
)
SETLOCAL EnableDelayedExpansion
set "param1=!param1:*#=!"
set "param1=!param1:~0,-2!"
echo %%1 is '!param1!'

The trick is to enable echo on and expand the %1 after a rem statement (works also with %2 .. %*).
So even "&"& could be echoed without producing an error, as it is remarked.

But to be able to redirect the output of the echo on, you need the two for-loops.

The extra characters * # are used to be safe against contents like /? (would show the help for REM).
Or a caret ^ at the line end could work as a multiline character, even in after a rem.

Then reading the rem parameter output from the file, but carefully.
The FOR /F should work with delayed expansion off, else contents with "!" would be destroyed.
After removing the extra characters in param1, you got it.

And to use param1 in a safe way, enable the delayed expansion.

There's no built in method to do that. You can use the expression:

(date1 > date2 ? date1 : date2)

to find the maximum of the two.

You can write a generic method to calculate Min or Max for any type (provided that Comparer<T>.Default is set appropriately):

public static T Max<T>(T first, T second) {
    if (Comparer<T>.Default.Compare(first, second) > 0)
        return first;
    return second;
}

You can use LINQ too:

new[]{date1, date2, date3}.Max()

You're not reading the file content:

my_file_contents = f.read()

See the docs for further infos

You could, without calling read() or readlines() loop over your file object:

f = open('goodlines.txt')
for line in f:
    print(line)

If you want a list out of it (without \n as you asked)

my_list = [line.rstrip('\n') for line in f]

You can do this.
When hovering to the .item1, it will change the .item2 element.

.item1 {
  size:100%;
}

.item1:hover
{
   .item2 {
     border:none;
   }
}

.item2{
  border: solid 1px blue;
}

First off, (though this won't change the performance at all) consider cleaning up your code, similar to this:

import matplotlib.pyplot as plt
import numpy as np
import time

x = np.arange(0, 2*np.pi, 0.01)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
lines = [ax.plot(x, y, style)[0] for ax, style in zip(axes, styles)]

fig.show()

tstart = time.time()
for i in xrange(1, 20):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    fig.canvas.draw()

print 'FPS:' , 20/(time.time()-tstart)

With the above example, I get around 10fps.

Just a quick note, depending on your exact use case, matplotlib may not be a great choice. It's oriented towards publication-quality figures, not real-time display.

However, there are a lot of things you can do to speed this example up.

There are two main reasons why this is as slow as it is.

1) Calling fig.canvas.draw() redraws everything. It's your bottleneck. In your case, you don't need to re-draw things like the axes boundaries, tick labels, etc.

2) In your case, there are a lot of subplots with a lot of tick labels. These take a long time to draw.

Both these can be fixed by using blitting.

To do blitting efficiently, you'll have to use backend-specific code. In practice, if you're really worried about smooth animations, you're usually embedding matplotlib plots in some sort of gui toolkit, anyway, so this isn't much of an issue.

However, without knowing a bit more about what you're doing, I can't help you there.

Nonetheless, there is a gui-neutral way of doing it that is still reasonably fast.

import matplotlib.pyplot as plt
import numpy as np
import time

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

fig.show()

# We need to draw the canvas before we start animating...
fig.canvas.draw()

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]

tstart = time.time()
for i in xrange(1, 2000):
    items = enumerate(zip(lines, axes, backgrounds), start=1)
    for j, (line, ax, background) in items:
        fig.canvas.restore_region(background)
        line.set_ydata(np.sin(j*x + i/10.0))
        ax.draw_artist(line)
        fig.canvas.blit(ax.bbox)

print 'FPS:' , 2000/(time.time()-tstart)

This gives me ~200fps.

To make this a bit more convenient, there's an animations module in recent versions of matplotlib.

As an example:

import matplotlib.pyplot as plt
import matplotlib.animation as animation
import numpy as np

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

def animate(i):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    return lines

# We'd normally specify a reasonable "interval" here...
ani = animation.FuncAnimation(fig, animate, xrange(1, 200), 
                              interval=0, blit=True)
plt.show()

This can be done with standard POSIX shell grammar.

Here is a simple count_entries function:

#!/usr/bin/env sh

count_entries()
{
  # Emulating Bash nullglob 
  # If argument 1 is not an existing entry
  if [ ! -e "$1" ]
    # argument is a returned pattern
    # then shift it out
    then shift
  fi
  echo $#
}

for a compact definition:

count_entries(){ [ ! -e "$1" ]&&shift;echo $#;}

Featured POSIX compatible file counter by type:

#!/usr/bin/env sh

count_files()
# Count the file arguments matching the file operator
# Synopsys:
# count_files operator FILE [...]
# Arguments:
# $1: The file operator
#   Allowed values:
#   -a FILE    True if file exists.
#   -b FILE    True if file is block special.
#   -c FILE    True if file is character special.
#   -d FILE    True if file is a directory.
#   -e FILE    True if file exists.
#   -f FILE    True if file exists and is a regular file.
#   -g FILE    True if file is set-group-id.
#   -h FILE    True if file is a symbolic link.

#   -N FILE    True if the file has been modified since it was last read.
# $@: The files arguments

{
  operator=$1
  shift
  case $operator in
    -[abcdefghLkprsStuwxOGN])
      for arg; do
        # If file is not of required type
        if ! test "$operator" "$arg"; then
          # Shift it out
          shift
        fi
      done
      echo $#
      ;;
    *)
      printf 'Invalid file operator: %s\n' "$operator" >&2
      return 1
      ;;
  esac

count_files -f log*.txt
count_files -d datadir*

I use the following script:

#!/usr/bin/python

import errno

import sys

toname = dict((str(getattr(errno, x)), x) 
              for x in dir(errno) 
              if x.startswith("E"))
tocode = dict((x, getattr(errno, x)) 
              for x in dir(errno) 
              if x.startswith("E"))

for arg in sys.argv[1:]:
    if arg in tocode:
        print arg, tocode[arg], os.strerror(tocode[arg])
    elif arg in toname:
        print toname[arg], arg, os.strerror(int(arg))
    else:
        print "Unknown:", arg

You can also use ng-pattern and I feel that will be a best practice. Similarly try to use ng-message. Please look the ng-pattern attribute on the following html. The code snippet is partial but hope you understand it.

angular.module('myApp', ['ngMessages']);
angular.module("myApp.controllers",[]).controller("registerCtrl", function($scope, Client) {
  $scope.ph_numbr = /^(\+?(\d{1}|\d{2}|\d{3})[- ]?)?\d{3}[- ]?\d{3}[- ]?\d{4}$/;
});

<form class="form-horizontal" role="form" method="post" name="registration" novalidate>
  <div class="form-group" ng-class="{ 'has-error' : (registration.phone.$invalid || registration.phone.$pristine)}">
    <label for="inputPhone" class="col-sm-3 control-label">Phone :</label>
    <div class="col-sm-9">
      <input type="number" class="form-control" ng-pattern="ph_numbr"  id="inputPhone" name="phone" placeholder="Phone" ng-model="user.phone" ng-required="true">
      <div class="help-block" ng-messages="registration.phone.$error">
        <p ng-message="required">Phone number is required.</p>
        <p ng-message="pattern">Phone number is invalid.</p>
      </div>
    </div>
  </div>
</form>

just use mCheckedPosition save status

@Override
        public void onBindViewHolder(ViewHolder holder, int position) {

            holder.checkBox.setChecked(position == mCheckedPostion);
            holder.checkBox.setOnClickListener(v -> {
                if (position == mCheckedPostion) {
                    holder.checkBox.setChecked(false);
                    mCheckedPostion = -1;
                } else {
                    mCheckedPostion = position;
                    notifyDataSetChanged();
                }
            });
        }

For Rails 5.2.4.1, I had to

app.extend app._routes.named_routes.path_helpers_module
app.whatever_path

I finally stumbled upon this link "A CORS POST request works from plain javascript, but why not with jQuery?" that notes that jQuery 1.5.1 adds the

 Access-Control-Request-Headers: x-requested-with

header to all CORS requests. jQuery 1.5.2 does not do this. Also, according to the same question, setting a server response header of

Access-Control-Allow-Headers: *

does not allow the response to continue. You need to ensure the response header specifically includes the required headers. ie:

Access-Control-Allow-Headers: x-requested-with

Sometimes changing document.body.innerHTML breaks some JS scripts on page. Here is version, that only changes content of text elements:

function replace(element, from, to) {
    if (element.childNodes.length) {
        element.childNodes.forEach(child => replace(child, from, to));
    } else {
        const cont = element.textContent;
        if (cont) element.textContent = cont.replace(from, to);
    }
};

replace(document.body, new RegExp("hello", "g"), "hi");

you can use $.param to assign data :

 $http({
  url: "http://example.appspot.com/rest/app",
  method: "POST",
  data: $.param({"foo":"bar"})
  }).success(function(data, status, headers, config) {
   $scope.data = data;
  }).error(function(data, status, headers, config) {
   $scope.status = status;
 });

For my private repository reference I didn't want to include a secure token, and none of the other simple (i.e. specifying only in package.json) worked. Here's what did work:

1. Went to GitHub.com
2. Navigated to Private Repository
3. Clicked "Clone or Download" and Copied URL (which didn't match the examples above)
4. Added #commit-sha
5. Ran npm install

You can also check single value in multiple arrays like,

if (grep /$match/, @array, @array_one, @array_two, @array_Three)
{
    print "found it\n";
}

Better late than never! Here is how we can do it(for learning purpose only)-

import java.util.List;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;

class SoftDrink {
    String name;
    String color;
    int volume; 

    SoftDrink (String name, String color, int volume) {
        this.name = name;
        this.color = color;
        this.volume = volume;
    }
}

public class ListItemComparision {
    public static void main (String...arg) {
        List<SoftDrink> softDrinkList = new ArrayList<SoftDrink>() ;
        softDrinkList .add(new SoftDrink("Faygo", "ColorOne", 4));
        softDrinkList .add(new SoftDrink("Fanta",  "ColorTwo", 3));
        softDrinkList .add(new SoftDrink("Frooti", "ColorThree", 2));       
        softDrinkList .add(new SoftDrink("Freshie", "ColorFour", 1));

        Collections.sort(softDrinkList, new Comparator() {
            @Override
            public int compare(Object softDrinkOne, Object softDrinkTwo) {
                //use instanceof to verify the references are indeed of the type in question
                return ((SoftDrink)softDrinkOne).name
                        .compareTo(((SoftDrink)softDrinkTwo).name);
            }
        }); 
        for (SoftDrink sd : softDrinkList) {
            System.out.println(sd.name + " - " + sd.color + " - " + sd.volume);
        }
        Collections.sort(softDrinkList, new Comparator() {
            @Override
            public int compare(Object softDrinkOne, Object softDrinkTwo) {
                //comparision for primitive int uses compareTo of the wrapper Integer
                return(new Integer(((SoftDrink)softDrinkOne).volume))
                        .compareTo(((SoftDrink)softDrinkTwo).volume);
            }
        });

        for (SoftDrink sd : softDrinkList) {
            System.out.println(sd.volume + " - " + sd.color + " - " + sd.name);
        }   
    }
}

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

use toUpperCase() or toLowerCase() method of String class.

Sometimes it is possible to have most of implementation hidden in cpp file, if you can extract common functionality foo all template parameters into non-template class (possibly type-unsafe). Then header will contain redirection calls to that class. Similar approach is used, when fighting with "template bloat" problem.

The three dot (...) notation is actually borrowed from mathematics, and it means "...and so on".

As for its use in Java, it stands for varargs, meaning that any number of arguments can be added to the method call. The only limitations are that the varargs must be at the end of the method signature and there can only be one per method.

uint32_t is standard, uint32 is not. That is, if you include <inttypes.h> or <stdint.h>, you will get a definition of uint32_t. uint32 is a typedef in some local code base, but you should not expect it to exist unless you define it yourself. And defining it yourself is a bad idea.

I modified @Alisa's code and used cProfile to show why list comprehension is faster:

    a = sum(a)
    return a

def map_(numbers):
    sqrt = lambda x: x*x
    return sum(map(sqrt, numbers))

def list_comp(numbers):
    return(sum([i*i for i in numbers]))

funcs = [

IMHO:

• reduce and map are in general pretty slow. Not only that, using sum on the iterators that map returned is slow, compared to suming a list
• for_loop uses append, which is of course slow to some extent
• list-comprehension not only spent the least time building the list, it also makes sum much quicker, in contrast to map

You can prefix the size requirement with - to left-justify:

sys.stdout.write("%-6s %-50s %-25s\n" % (code, name, industry))

When I got the same error on my machine ("connection is refused"), the reason was that I had defined the following on the server side:

 Naming.rebind("rmi://localhost:8080/AddService"
   ,addService); 

Thus the server binds both the IP = 127.0.0.1 and the port 8080.

But on the client side I had used:

AddServerInterface st = (AddServerInterface)Naming.lookup("rmi://localhost"
                        +"/AddService");

Thus I forgot to add the port number after the localhost, so I rewrote the above command and added the port number 8080 as follows:

AddServerInterface st = (AddServerInterface)Naming.lookup("rmi://localhost:8080"
                        +"/AddService");

and everything worked fine.

I personally use Cygwin, which puts the entire smörgåsbord of Linux utilities at my fingertip --- there's md5sum and all the cryptographic digests supported by OpenSSL. Alternatively, you can also use a Windows distribution of OpenSSL (the "light" version is only a 1 MB installer).

you can also try

var query = from p in list
            where p.Age > 18
            select p;

you can do

strings test.log | grep -i

this will convert give output as a readable string to grep.

class CountryListView(ListView):
     model = Country

    def render_to_response(self, context, **response_kwargs):

         return HttpResponse(json.dumps(list(self.get_queryset().values_list('code', flat=True))),mimetype="application/json") 

fixed the problem

also mimetype is important.

A belated post:
Use the search regex pattern as a Record Separator (RS) in awk
This allows your regex to span \n-delimited lines (if you need it).

printf 'X \n moo X\n XX\n' | 
   awk -vRS='X[^X]*X' 'END{print (NR<2?0:NR-1)}'

Make clear you have pass a value in your MainAcitivity for the following methods onCreateOptionsMenu and onCreate

In some cases, the developer deletes the "return super.onCreateOptionsMenu(menu)" statement and changed to "return true".

You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#parent-selector

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

A better, more modern, answer to this question is to use the %pip magic, like:

%pip install scipy

That will automatically use the correct Python version. Using !pip might be tied to a different version of Python, and then you might not find the package after installing it.

And in colab, the magic gives a nice message and button if it detects that you need to restart the runtime if pip updated a packaging you have already imported.

BTW, there is also a %conda magic for doing the same with conda.

https://developer.mozilla.org/en-US/docs/Web/CSS/initial

use initial property in css3

 <p style="color:red!important"> 
    this text is red 
       <em style="color:initial"> 
          this text is in the initial color (e.g. black)
       </em>
    this is red again
 </p>

An easily broken way to do this is :

<?php
// Send the headers
header('Content-type: text/xml');
header('Pragma: public');
header('Cache-control: private');
header('Expires: -1');
echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>";

echo '<xml>';

// echo some dynamically generated content here
/*
<track>
    <path>song_path</path>
    <title>track_number - track_title</title>
</track>
*/

echo '</xml>';

?>

save it as .php

If you need to scroll to the EXACT end of the content, you can do it like this:

- (void)scrollToBottom
{
    CGFloat yOffset = 0;

    if (self.tableView.contentSize.height > self.tableView.bounds.size.height) {
        yOffset = self.tableView.contentSize.height - self.tableView.bounds.size.height;
    }

    [self.tableView setContentOffset:CGPointMake(0, yOffset) animated:NO];
}

In your TS Definition file, e.g. typings.d.ts`, you can add this line:

declare module "*.json" {
const value: any;
export default value;
}

Then add this in your typescript(.ts) file:-

import * as data from './colors.json';
const word = (<any>data).name;

The height of the containing divs (full and someid) should be set to "auto". That's all.

Hello I was searching for a solution to reverse sorting a two dimensional numpy array, and I couldn't find anything that worked, but I think I have stumbled on a solution which I am uploading just in case anyone is in the same boat.

x=np.sort(array)
y=np.fliplr(x)

np.sort sorts ascending which is not what you want, but the command fliplr flips the rows left to right! Seems to work!

Hope it helps you out!

I guess it's similar to the suggest about -np.sort(-a) above but I was put off going for that by comment that it doesn't always work. Perhaps my solution won't always work either however I have tested it with a few arrays and seems to be OK.

A simple answer to this question can be:

1. Read A Number "n" From The User.
2. Using While Loop Make Sure Its Not Zero.
3. Take modulus 10 Of The Number "n"..This Will Give You Its Last Digit.
4. Then Divide The Number "n" By 10..This Removes The Last Digit of Number "n" since in int decimal part is omitted.
5. Display Out The Number.

I Think It Will Help. I Used Simple Code Like:

#include <iostream>
using namespace std;
int main()
{int n,r;

    cout<<"Enter Your Number:";
    cin>>n;


    while(n!=0)
    {
               r=n%10;
               n=n/10;

               cout<<r;
    }
    cout<<endl;

    system("PAUSE");
    return 0;
}

In Java, all public (non-private) variables & functions are Virtual by default. Moreover variables & functions using keyword final are not virtual.

If still help, verify the name of archive, it must be exact "log4j.properties" or "log4j.xml" (case sensitive), and follow the hint by "Alain O'Dea". I was geting the same error, but after make these changes everthing works fine. just like a charm :-). hope this helps.

This is a universal wrapper for hover written in typescript. The component will apply style passed via props 'hoverStyle' on hover event.

import React, { useState } from 'react';

export const Hover: React.FC<{
  style?: React.CSSProperties;
  hoverStyle: React.CSSProperties;
}> = ({ style = {}, hoverStyle, children }) => {
  const [isHovered, setHovered] = useState(false);
  const calculatedStyle = { ...style, ...(isHovered ? hoverStyle : {}) };
  return (
    <div
      style={calculatedStyle}
      onMouseEnter={() => setHovered(true)}
      onMouseLeave={() => setHovered(false)}
    >
      {children}
    </div>
  );
};    

It means you compiled with e.g. gcc -O3 and the gcc optimiser found that some of your variables were redundant in some way that allowed them to be optimised away. In this particular case you appear to have three variables a, b, c with the same value and presumably they can all be aliassed to a single variable. Compile with optimisation disabled, e.g. gcc -O0, if you want to see such variables (this is generally a good idea for debug builds in any case).

Here is the max value and the indexes it appears at:

>>> from collections import defaultdict
>>> d = defaultdict(list)
>>> a = [32, 37, 28, 30, 37, 25, 27, 24, 35, 55, 23, 31, 55, 21, 40, 18, 50, 35, 41, 49, 37, 19, 40, 41, 31]
>>> for i, x in enumerate(a):
...     d[x].append(i)
... 
>>> k = max(d.keys())
>>> print k, d[k]
55 [9, 12]

Later: for the satisfaction of @SilentGhost

>>> from itertools import takewhile
>>> import heapq
>>> 
>>> def popper(heap):
...     while heap:
...         yield heapq.heappop(heap)
... 
>>> a = [32, 37, 28, 30, 37, 25, 27, 24, 35, 55, 23, 31, 55, 21, 40, 18, 50, 35, 41, 49, 37, 19, 40, 41, 31]
>>> h = [(-x, i) for i, x in enumerate(a)]
>>> heapq.heapify(h)
>>> 
>>> largest = heapq.heappop(h)
>>> indexes = [largest[1]] + [x[1] for x in takewhile(lambda large: large[0] == largest[0], popper(h))]
>>> print -largest[0], indexes
55 [9, 12]

If you are running in Android 29 then you have to use scoped storage or for now, you can bypass this issue by using:

android:requestLegacyExternalStorage="true"

in manifest in the application tag.

Doing type('') is effectively equivalent to str and types.StringType

so type('') == str == types.StringType will evaluate to "True"

Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode) or assert isinstance(obj, basestring), the latter of which was suggested in the comments by 007Brendan and is probably preferred.

isinstance() is useful if you want to ask whether an object is an instance of a class, e.g:

class MyClass: pass

print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception

But for basic types, e.g. str, unicode, int, float, long etc asking type(var) == TYPE will work OK.

C# simple algorithm. (I'm posting it since I've tried to use the one you guys uploaded, but for some reason I couldn't compile it - extending a class? so I wrote my own one just in case someone else is facing the same problem I did). I'm not much into c# more than basic programming by the way, but this one works fine.

public static List<List<int>> GetSubsetsOfSizeK(List<int> lInputSet, int k)
        {
            List<List<int>> lSubsets = new List<List<int>>();
            GetSubsetsOfSizeK_rec(lInputSet, k, 0, new List<int>(), lSubsets);
            return lSubsets;
        }

public static void GetSubsetsOfSizeK_rec(List<int> lInputSet, int k, int i, List<int> lCurrSet, List<List<int>> lSubsets)
        {
            if (lCurrSet.Count == k)
            {
                lSubsets.Add(lCurrSet);
                return;
            }

            if (i >= lInputSet.Count)
                return;

            List<int> lWith = new List<int>(lCurrSet);
            List<int> lWithout = new List<int>(lCurrSet);
            lWith.Add(lInputSet[i++]);

            GetSubsetsOfSizeK_rec(lInputSet, k, i, lWith, lSubsets);
            GetSubsetsOfSizeK_rec(lInputSet, k, i, lWithout, lSubsets);
        }

USAGE: GetSubsetsOfSizeK(set of type List<int>, integer k)

You can modify it to iterate over whatever you are working with.

Good luck!

You can create multiple workspaces in Eclipse. You have to just specify the path of the workspace during Eclipse startup. You can even switch workspaces via File?Switch workspace.

You can then import project to your workspace, copy paste project to your new workspace folder, then

File?Import?Existing project in to workspace?select project.

As already stated, enum instances should be uppercase according to the docs on the Oracle website (http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html).

However, while looking through a JavaEE7 tutorial on the Oracle website (http://www.oracle.com/technetwork/java/javaee/downloads/index.html), I stumbled across the "Duke's bookstore" tutorial and in a class (tutorial\examples\case-studies\dukes-bookstore\src\main\java\javaeetutorial\dukesbookstore\components\AreaComponent.java), I found the following enum definition:

private enum PropertyKeys {
    alt, coords, shape, targetImage;
}

According to the conventions, it should have looked like:

public enum PropertyKeys {
    ALT("alt"), COORDS("coords"), SHAPE("shape"), TARGET_IMAGE("targetImage");

    private final String val;

    private PropertyKeys(String val) {
        this.val = val;
    }

    @Override
    public String toString() {
        return val;
    }
}

So it seems even the guys at Oracle sometimes trade convention with convenience.

A simple solution is to set the spring bean in the Job Data Map and then retrieve the bean in the job class, for instance

// the class sets the configures the MyJob class 
    SchedulerFactory sf = new StdSchedulerFactory();
    Scheduler sched = sf.getScheduler();
    Date startTime = DateBuilder.nextGivenSecondDate(null, 15);
    JobDetail job = newJob(MyJob.class).withIdentity("job1", "group1").build();
    job.getJobDataMap().put("processDataDAO", processDataDAO);

`

 // this is MyJob Class
    ProcessDataDAO processDataDAO = (ProcessDataDAO) jec.getMergedJobDataMap().get("processDataDAO");

Comparator.comparing

In Java 8, Collections have been enhanced by using lambda. So finding max and min can be accomplished as follows, using Comparator.comparing:

Code:

List<Integer> ints = Stream.of(12, 72, 54, 83, 51).collect(Collectors.toList());
System.out.println("the list: ");
ints.forEach((i) -> {
    System.out.print(i + " ");
});
System.out.println("");
Integer minNumber = ints.stream()
        .min(Comparator.comparing(i -> i)).get();
Integer maxNumber = ints.stream()
        .max(Comparator.comparing(i -> i)).get();

System.out.println("Min number is " + minNumber);
System.out.println("Max number is " + maxNumber);

Output:

 the list: 12 72 54 83 51  
 Min number is 12 
 Max number is 83

I think you've answered your own question: try not to go beyond the 70 Mb limit, however it really depends on many things: what iOS version you're using (not SDK), how many applications running in background, what exact memory you're using etc.

Just avoid the instant memory splashes (e.g. you're using 40 Mb of RAM, and then allocating 80 Mb's more for some short computation). In this case iOS would kill your application immediately.

You should also consider lazy loading of assets (load them only when you really need and not beforehand).

It's an automatically backed property, basically equivalent to:

private string type;
public string Type
{
   get{ return type; }
   set{ type = value; }
}

Is this what you're looking for?:

:"Book Author Title"

This may seem slightly off topic but this was the post I came across when wondering what happens when you read a column as a dateTime in c#. The post reflects the information I would have liked to be able to find about this mechanism. If you worry about utc and timezones then read on

I did a little more research as I'm always very wary of DateTime as a class because of its automatic assumptions about what timezone you are using and because it is way too easy to confuse local times and utc times.

What I'm trying to avoid here is DateTime going 'oh look the computer I'm being run on is in timezone x, therefore this time must also be in timezone x, when I get asked for my values I'll reply as if I'm in that timezone'

I was trying to read a datetime2 column.

The date time you will get back from sql server will end up being of Kind.Unspecified this seems to mean it gets treated like UTC, which is what I wanted.

When reading a date column you also have to read it as a DateTime even though it has no time and is even more prone to screwing up by timezones (as it is on midnight).

I'd certainly consider this to be safer way of reading the DateTime as I suspect it can probably be modified by either settings in sql server or static settings in your c#:

var time = reader.GetDateTime(1);
var utcTime = new DateTime(time.Ticks, DateTimeKind.Utc);

From there you can get the components (Day, Month, Year) etc and format how you like.

If what you have is actually a date + a time then Utc might not be what you want there - since you are mucking around on the client you may need to convert it to a local time first (depending on what the meaning of the time is). However that opens up a whole can of worms.. If you need to do that I'd recommend using a library like noda time. There is TimeZoneInfo in the standard library but after briefly investigating it, it doesn't seem to have a proper set of timezones. You can see the list provided by TimeZoneInfo by using the method TimeZoneInfo.GetSystemTimeZones();

I also discovered sql server management studio doesn't convert times to local time before displaying them. Which is a relief!

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

try this. http://jsfiddle.net/fVpkm/

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

You can use combination of View, Icon and TextInput like so:

<View style={styles.searchSection}>
    <Icon style={styles.searchIcon} name="ios-search" size={20} color="#000"/>
    <TextInput
        style={styles.input}
        placeholder="User Nickname"
        onChangeText={(searchString) => {this.setState({searchString})}}
        underlineColorAndroid="transparent"
    />
</View>

and use flex-direction for styling

searchSection: {
    flex: 1,
    flexDirection: 'row',
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#fff',
},
searchIcon: {
    padding: 10,
},
input: {
    flex: 1,

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.

location / {
    proxy_pass                      http://example.com;
    proxy_set_header                Host example.com;
    proxy_set_header                HTTP_Country-Code $geoip_country_code;
    proxy_pass_request_headers      on;
}

And now it's passed to the proxy backend.

There is U+1F50D LEFT-POINTING MAGNIFYING GLASS () and U+1F50E RIGHT-POINTING MAGNIFYING GLASS ().

You should use (in HTML) 🔍 or 🔎

They are, however not supported by many fonts (fileformat.info only lists a few fonts as supporting the Codepoint with a proper glyph).

Also note that they are outside of the BMP, so some Unicode-capable software might have problems rendering them, even if they have fonts that support them.

Generally Unicode Glyphs can be searched using a site such as fileformat.info. This searches "only" in the names and properties of the Unicode glyphs, but they usually contain enough metadata to allow for good search results (for this answer I searched for "glass" and browsed the resulting list, for example)

As in the docs, if you are on windows you can use hyperv drivers.

Docker for Windows - You can use docker-machine create with the hyperv driver to create additional local machines.

You can see marked answer on top. But i used getDialog().getCurrentFocus() and working well. I post this answer cause i cant type "this" in my oncreatedialog.

So this is my answer. If you tried marked answer and not worked , you can simply try this:

InputMethodManager inputManager = (InputMethodManager) getActivity().getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(getDialog().getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

I settled on a more general-purpose solution that allows concatenating an arbitrary set of one-dimensional arrays of the same type. (I was concatenating 3+ at a time.)

My function:

    public static T[] ConcatArrays<T>(params T[][] list)
    {
        var result = new T[list.Sum(a => a.Length)];
        int offset = 0;
        for (int x = 0; x < list.Length; x++)
        {
            list[x].CopyTo(result, offset);
            offset += list[x].Length;
        }
        return result;
    }

And usage:

        int[] a = new int[] { 1, 2, 3 };
        int[] b = new int[] { 4, 5, 6 };
        int[] c = new int[] { 7, 8 };
        var y = ConcatArrays(a, b, c); //Results in int[] {1,2,3,4,5,6,7,8}

I find this to be concise and self-documenting:

[true, false].include? foo

If using Rails or ActiveSupport, you can even do a direct query using in?

foo.in? [true, false]

Checking against all possible values isn't something I'd recommend for floats, but feasible when there are only two possible values!

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com
