IDisposable is often used to exploit the using statement and take advantage of an easy way to do deterministic cleanup of managed objects.

public class LoggingContext : IDisposable {
    public Finicky(string name) {
        Log.Write("Entering Log Context {0}", name);
        Log.Indent();
    }
    public void Dispose() {
        Log.Outdent();
    }

    public static void Main() {
        Log.Write("Some initial stuff.");
        try {
            using(new LoggingContext()) {
                Log.Write("Some stuff inside the context.");
                throw new Exception();
            }
        } catch {
            Log.Write("Man, that was a heavy exception caught from inside a child logging context!");
        } finally {
            Log.Write("Some final stuff.");
        }
    }
}

ImageMagick and GD can handle PNGs too; heck, you could even do stuff with nothing but gdk-pixbuf. Are you looking for a graphical editor, or scriptable/embeddable libraries?

$url="http://www.google.co.in/intl/en_com/images/srpr/logo1w.png";
$contents=file_get_contents($url);
$save_path="/path/to/the/dir/and/image.jpg";
file_put_contents($save_path,$contents);

you must have allow_url_fopen set to on

This worked for me. With the method mentioned here I was able to draw polylines on Google Maps V2. I drew a new line whenever the user location got changed, so the the polyline looks like the path followed by user on map.

Based on Merrill's answer here is how to do with a CursorAdapter

CursorAdapter myAdapter = (CursorAdapter) spinner_listino.getAdapter(); //cast
    for(int i = 0; i < myAdapter.getCount(); i++)
    {
        if (myAdapter.getItemId(i) == ordine.getListino() )
        {
            this.spinner_listino.setSelection(i);
            break;
        }
    }

Here's a solution with flexbox for images with variable width and height:

.container {
  display: flex;

  flex: 0 0 auto;
  width: auto;
  height: 100px;
  max-width: 100%;
  margin-right: 10px;
}

Not a single answer here actually answers the question. The OP did not ask about a singleton/per-application DbContext design, he asked about a per-(web)request design and what potential benefits could exist.

I'll reference http://mehdi.me/ambient-dbcontext-in-ef6/ as Mehdi is a fantastic resource:

Possible performance gains.

Each DbContext instance maintains a first-level cache of all the entities its loads from the database. Whenever you query an entity by its primary key, the DbContext will first attempt to retrieve it from its first-level cache before defaulting to querying it from the database. Depending on your data query pattern, re-using the same DbContext across multiple sequential business transactions may result in a fewer database queries being made thanks to the DbContext first-level cache.

It enables lazy-loading.

If your services return persistent entities (as opposed to returning view models or other sorts of DTOs) and you'd like to take advantage of lazy-loading on those entities, the lifetime of the DbContext instance from which those entities were retrieved must extend beyond the scope of the business transaction. If the service method disposed the DbContext instance it used before returning, any attempt to lazy-load properties on the returned entities would fail (whether or not using lazy-loading is a good idea is a different debate altogether which we won't get into here). In our web application example, lazy-loading would typically be used in controller action methods on entities returned by a separate service layer. In that case, the DbContext instance that was used by the service method to load these entities would need to remain alive for the duration of the web request (or at the very least until the action method has completed).

Keep in mind there are cons as well. That link contains many other resources to read on the subject.

Just posting this in case someone else stumbles upon this question and doesn't get absorbed in answers that don't actually address the question.

I can offer only an example of the layout solution already pointed out.

layout(matrix(c(1,2), nrow = 1), widths = c(0.7, 0.3))
par(mar = c(5, 4, 4, 2) + 0.1)
plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")
par(mar = c(5, 0, 4, 2) + 0.1)
plot(1:3, rnorm(3), pch = 1, lty = 1, ylim=c(-2,2), type = "n", axes = FALSE, ann = FALSE)
legend(1, 1, c("group A", "group B"), pch = c(1,2), lty = c(1,2))

If the other class is compiled as a library (i.e. a dll) and this is how you want it, you should add a reference from visual studio, browse and point to to the dll file.

If what you want is to incorporate the OtherClassFile.cs into your project, and the namespace is already identical, you can:

1. Close your solution,

2. Open YourProjectName.csproj file, and look for this section:

   <ItemGroup>                                            
       <Compile Include="ExistingClass1.cs" />                     
       <Compile Include="ExistingClass2.cs" />                                 
       ...
       <Compile Include="Properties\AssemblyInfo.cs" />     
   </ItemGroup>
   

1. Check that the .cs file that you want to add is in the project folder (same folder as all the existing classes in the solution).

2. Add an entry inside as below, save and open the project.

   <Compile Include="OtherClassFile.cs" /> 
   

Your class, will now appear and behave as part of the project. No using is needed. This can be done multiple files in one shot.

I love jQuery's method chaining. Simply do...

    var value = $("#text").val().replace('.',':');

    //Or if you want to return the value:
    return $("#text").val().replace('.',':');

You can try creating a css for your font with font-face (like explained here)

Step #1

Create a css file with font face and place it somewhere, like in assets/fonts

customfont.css

@font-face {
    font-family: YourFontFamily;
    src: url("/assets/font/yourFont.otf") format("truetype");
}

Step #2

Add the css to your .angular-cli.json in the styles config

"styles":[
 //...your other styles
 "assets/fonts/customFonts.css"
 ]

Do not forget to restart ng serve after doing this

Step #3

Use the font in your code

component.css

span {font-family: YourFontFamily; }

getting a char from a string may depend on the enconding (string default is UTF-16)

https://stackoverflow.com/a/32141891

string str = new String(new char[] { '\uD800', '\uDC00', 'z' });
string first = str.Substring(0, char.IsHighSurrogate(str[0]) ? 2 : 1);

They way I handle this problem is recursively. For example when reading data from the console:

Java.util.Scanner keyboard = new Java.util.Scanner(System.in);

public int GetMyInt(){
    int ret;
    System.out.print("Give me an Int: ");
    try{
        ret = Integer.parseInt(keyboard.NextLine());

    }
    catch(Exception e){
        System.out.println("\nThere was an error try again.\n");
        ret = GetMyInt();
    }
    return ret;
}

To start server locally paste the below code in package.json and run npm start in command line.

"scripts": { "start": "http-server -c-1 -p 8081" },

If you don't mind logging the message also to syslog, the not_so_ugly way is:

logger -s $msg

The -s option means: "Output the message to standard error as well as to the system log."

I use this simple function, which returns true or false, to test for localStorage availablity:

isLocalStorageNameSupported = function() {
    var testKey = 'test', storage = window.sessionStorage;
    try {
        storage.setItem(testKey, '1');
        storage.removeItem(testKey);
        return true;
    } catch (error) {
        return false;
    }
}

Now you can test for localStorage.setItem() availability before using it. Example:

if ( isLocalStorageNameSupported() ) {
    // can use localStorage.setItem('item','value')
} else {
    // can't use localStorage.setItem('item','value')
}

You can set left margins for li tags in percents and set the same negative left margin on parent:

ul {margin-left:-5%;}_x000D_
li {width:20%;margin-left:5%;float:left;}

<ul>_x000D_
  <li>A_x000D_
  <li>B_x000D_
  <li>C_x000D_
  <li>D_x000D_
</ul>

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

Try this one:

HTML:

<div id="para1"></div>

JavaScript:

document.getElementById("para1").innerHTML = formatAMPM();

function formatAMPM() {
var d = new Date(),
    minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
    hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
    ampm = d.getHours() >= 12 ? 'pm' : 'am',
    months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;
}

Result:

Please! Just ask w3 (http://www.quirksmode.org/dom/w3c_css.html)! Or actually, it took me five hours... but here it is!

function css(selector, property, value) {
    for (var i=0; i<document.styleSheets.length;i++) {//Loop through all styles
        //Try add rule
        try { document.styleSheets[i].insertRule(selector+ ' {'+property+':'+value+'}', document.styleSheets[i].cssRules.length);
        } catch(err) {try { document.styleSheets[i].addRule(selector, property+':'+value);} catch(err) {}}//IE
    }
}

The function is really easy to use.. example:

<div id="box" class="boxes" onclick="css('#box', 'color', 'red')">Click Me!</div>
Or:
<div class="boxes" onmouseover="css('.boxes', 'color', 'green')">Mouseover Me!</div>
Or:
<div class="boxes" onclick="css('body', 'border', '1px solid #3cc')">Click Me!</div>

Oh..

(function (scope) {
    // Create a new stylesheet in the bottom
    // of <head>, where the css rules will go
    var style = document.createElement('style');
    document.head.appendChild(style);
    var stylesheet = style.sheet;
    scope.css = function (selector, property, value) {
        // Append the rule (Major browsers)
        try { stylesheet.insertRule(selector+' {'+property+':'+value+'}', stylesheet.cssRules.length);
        } catch(err) {try { stylesheet.addRule(selector, property+':'+value); // (pre IE9)
        } catch(err) {console.log("Couldn't add style");}} // (alien browsers)
    }
})(window);

I think many people reading this post will be looking for simpler regular expressions, even if they match some technically invalid IP addresses. (And, as noted elsewhere, regex probably isn't the right tool for properly validating an IP address anyway.)

Remove ^ and, where applicable, replace $ with \b, if you don't want to match the beginning/end of the line.

Basic Regular Expression (BRE) (tested on GNU grep, GNU sed, and vim):

/^[0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+$/

Extended Regular Expression (ERE):

/^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$/

or:

/^([0-9]+(\.|$)){4}/

Perl-compatible Regular Expression (PCRE) (tested on Perl 5.18):

/^\d+\.\d+\.\d+\.\d+$/

or:

/^(\d+(\.|$)){4}/

Ruby (tested on Ruby 2.1):

Although supposed to be PCRE, Ruby for whatever reason allowed this regex not allowed by Perl 5.18:

/^(\d+[\.$]){4}/

My tests for all these are online here.

If you know the number of levels in nested arrays you can simply do nested loops. Like so:

//  Scan through outer loop
foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

if you do not know the depth of array you need to use recursion. See example below:

//  Multi-dementional Source Array
$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(
            7,
            8,
            array("four", 9, 10)
    ))
);

//  Output array
displayArrayRecursively($tmpArray);

/**
 * Recursive function to display members of array with indentation
 *
 * @param array $arr Array to process
 * @param string $indent indentation string
 */
function displayArrayRecursively($arr, $indent='') {
    if ($arr) {
        foreach ($arr as $value) {
            if (is_array($value)) {
                //
                displayArrayRecursively($value, $indent . '--');
            } else {
                //  Output
                echo "$indent $value \n";
            }
        }
    }
}

The code below with display only nested array with values for your specific case (3rd level only)

$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(7, 8, 9))
);

//  Scan through outer loop
foreach ($tmpArray as $inner) {

    //  Check type
    if (is_array($inner)) {
        //  Scan through inner loop
        foreach ($inner[1] as $value) {
           echo "$value \n";
        }
    }
}

There's now a C/C++ language extension from Microsoft. You can install it by going to the "quick open" thing (Ctrl+p) and typing:

ext install cpptools

You can read about it here:

https://blogs.msdn.microsoft.com/vcblog/2016/03/31/cc-extension-for-visual-studio-code/

It's very basic, as of May 2016.

Your main problem is that you are calling a method called first() in the iterator. What you are meant to do is use the property called first:

...append(iter->first) rather than ...append(iter->first())

As a matter of style, you shouldn't be using new to create that string.

std::string something::toString() 
{
        std::map<std::string, std::string>::iterator iter;
        std::string strToReturn; //This is no longer on the heap

        for (iter = table.begin(); iter != table.end(); ++iter) {
           strToReturn.append(iter->first); //Not a method call
           strToReturn.append("=");
           strToReturn.append(iter->second);
           //....
           // Make sure you don't modify table here or the iterators will not work as you expect
        }
        //...
        return strToReturn;
}

edit: facildelembrar pointed out (in the comments) that in modern C++ you can now rewrite the loop

for (auto& item: table) {
    ...
}

Just Re install the turbo C++ from your Computer and install again in the Directory C:\TC\ Folder.

Again The Problem exists ,then change the directory from FILE>>CHANGE DIRECTORY to C:\TC\BIN\

The space before the = is interpreted as part of the name, and the space after it (as well as the quotation marks) are interpreted as part of the value. So the variable you’ve created can be referenced with %location %. If that’s not what you want, remove the extra space(s) in the definition.

If you dont have phpMyAdmin, you can write in php CLI commands such as login to mysql and perform db dump. In this case you would use shell_exec function.

Simple nltk.download() will not solve this issue. I tried the below and it worked for me:

in the nltk folder create a tokenizers folder and copy your punkt folder into tokenizers folder.

This will work.! the folder structure needs to be as shown in the picture

That's not really a question of aesthetics, but indeed a technical difference. The directory thinking of it is totally correct and pretty much explaining everything. Let's work it out:

You are back in the stone age now or only serve static pages

You have a fixed directory structure on your web server and only static files like images, html and so on — no server side scripts or whatsoever.

A browser requests /index.htm, it exists and is delivered to the client. Later you have lots of - let's say - DVD movies reviewed and a html page for each of them in the /dvd/ directory. Now someone requests /dvd/adams_apples.htm and it is delivered because it is there.

At some day, someone just requests /dvd/ - which is a directory and the server is trying to figure out what to deliver. Besides access restrictions and so on there are two possibilities: Show the user the directory content (I bet you already have seen this somewhere) or show a default file (in Apache it is: DirectoryIndex: sets the file that Apache will serve if a directory is requested.)

So far so good, this is the expected case. It already shows the difference in handling, so let's get into it:

At 5:34am you made a mistake uploading your files

(Which is by the way completely understandable.) So, you did something entirely wrong and instead of uploading /dvd/the_big_lebowski.htm you uploaded that file as dvd (with no extension) to /.

Someone bookmarked your /dvd/ directory listing (of course you didn't want to create and always update that nifty index.htm) and is visiting your web-site. Directory content is delivered - all fine.

Someone heard of your list and is typing /dvd. And now it is screwed. Instead of your DVD directory listing the server finds a file with that name and is delivering your Big Lebowski file.

So, you delete that file and tell the guy to reload the page. Your server looks for the /dvd file, but it is gone. Most servers will then notice that there is a directory with that name and tell the client that what it was looking for is indeed somewhere else. The response will most likely be be:

Status Code:301 Moved Permanently with Location: http://[...]/dvd/

So, totally ignoring what you think about directories or files, the server only can handle such stuff and - unless told differently - decides for you about the meaning of "slash or not".

Finally after receiving this response, the client loads /dvd/ and everything is fine.

Is it fine? No.

"Just fine" is not good enough for you

You have some dynamic page where everything is passed to /index.php and gets processed. Everything worked quite good until now, but that entire thing starts to feel slower and you investigate.

Soon, you'll notice that /dvd/list is doing exactly the same: Redirecting to /dvd/list/ which is then internally translated into index.php?controller=dvd&action=list. One additional request - but even worse! customer/login redirects to customer/login/ which in turn redirects to the HTTPS URL of customer/login/. You end up having tons of unnecessary HTTP redirects (= additional requests) that make the user experience slower.

Most likely you have a default directory index here, too: index.php?controller=dvd with no action simply internally loads index.php?controller=dvd&action=list.

Summary:

• If it ends with / it can never be a file. No server guessing.

• Slash or no slash are entirely different meanings. There is a technical/resource difference between "slash or no slash", and you should be aware of it and use it accordingly. Just because the server most likely loads /dvd/index.htm - or loads the correct script stuff - when you say /dvd: It does it, but not because you made the right request. Which would have been /dvd/.

• Omitting the slash even if you indeed mean the slashed version gives you an additional HTTP request penalty. Which is always bad (think of mobile latency) and has more weight than a "pretty URL" - especially since crawlers are not as dumb as SEOs believe or want you to believe ;)

you said that:

`mony = float(1234.5)
print(money)      #output is 1234.5
'${:,.2f}'.format(money)
print(money)

did not work.... Have you coded exactly that way? This should work (see the little difference):

money = float(1234.5)      #next you used format without printing, nor affecting value of "money"
amountAsFormattedString = '${:,.2f}'.format(money)
print( amountAsFormattedString )

Note: ||= does not exist. (logical or) You can use

y= y || expr; // expr is NOT evaluated if y==true

or

y = expr ? true : y;  // expr is always evaluated.

The following works for me:

git diff master:foo foo

In the past, it may have been:

git diff foo master:foo

Try this... I have tried and work fine for me

This issue is related to low memory...

Close your browsers, visual Studio and other services..

after that run following command

ionic build android 

it will run successfully..

//Solutions is
create "gradle.properties" file in android folder and add following line into file
org.gradle.jvmargs=-Xmx512m -XX:MaxPermSize=512m

<your project>\platforms\android\gradle.properties

You can open browser and others..

ionic build android

Now it will work fine.

Regular Expression HOWTO

span() returns both start and end indexes in a single tuple. Since the match method only checks if the RE matches at the start of a string, start() will always be zero. However, the search method of RegexObject instances scans through the string, so the match may not start at zero in that case.

>>> p = re.compile('[a-z]+')
>>> print p.match('::: message')
None
>>> m = p.search('::: message') ; print m
<re.MatchObject instance at 80c9650>
>>> m.group()
'message'
>>> m.span()
(4, 11)

Combine that with:

In Python 2.2, the finditer() method is also available, returning a sequence of MatchObject instances as an iterator.

>>> p = re.compile( ... )
>>> iterator = p.finditer('12 drummers drumming, 11 ... 10 ...')
>>> iterator
<callable-iterator object at 0x401833ac>
>>> for match in iterator:
...     print match.span()
...
(0, 2)
(22, 24)
(29, 31)

you should be able to do something on the order of

for match in re.finditer(r'[a-z]', 'a1b2c3d4'):
   print match.span()

Answer

You have multiple options:

1. background-size: 100% 100%; - image gets stretched (aspect ratio may be preserved, depending on browser)
2. background-size: contain; - image is stretched without cutting it while preserving aspect ratio
3. background-size: cover; - image is completely covering the element while preserving aspect ratio (image can be cut off)

Based on the answer here, I think you need to change the xmlns:ads attribute. For example, change this:

<com.google.ads.AdView 
    xmlns:ads="http://schemas.android.com/apk/res/com.google.example"
    ...
    />

to this:

<com.google.ads.AdView

Depending on the AWK implementation are you using == is ok or not.

Have you tried ~?. For example, if you want $1 to be "hello":

awk '$1 ~ /^hello$/{ print $3; }' <infile>

^ means $1 start, and $ is $1 end.

You can't run 16-bit applications (or components) on 64-bit versions of Windows. That emulation layer no longer exists. The 64-bit versions already have to provide a compatibility layer for 32-bit applications.

Support for 16-bit had to be dropped eventually, even in a culture where backwards-compatibility is of sacred import. The transition to 64-bit seemed like as good a time as any. It's hard to imagine anyone out there in the wild that is still using 16-bit applications and seeking to upgrade to 64-bit OSes.

What would be the best way to get round this problem?

If the component itself is 16-bit, then using a virtual machine running a 32-bit version of Windows is your only real choice. Oracle's VirtualBox is free, and a perennial favorite.

If only the installer is 16-bit (and it installs a 32-bit component), then you might be able to use a program like 7-Zip to extract the contents of the installer and install them manually. Let's just say this "solution" is high-risk and you should have few, if any, expectations.

It's high time to upgrade away from 16-bit stuff, like Turbo C++ and Sheridan controls. I've yet to come across anything that the Sheridan controls can do that the built-in controls can't do and haven't been able to do since Windows 95.

To find all including empty lines of code try @Neil's solution:

Open Find in Path (Ctrl+Shift+F)

Search for the following regular expression: \n'

For lines with at least one character use following expression:

(.+)\n

For lines with at least one word character or digit use following expression:

`(.*)([\w\d]+)(.*)\n`

Notice: But the last line of file is just counted if you have a line break after it.

Thought I'd consolidate the answers and show some timeit results.

Python 2 sucks pretty bad at this, but map is a bit faster than comprehension.

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> setup = """import random
random.seed(10)
l = [str(random.randint(0, 99)) for i in range(100)]"""
>>> timeit.timeit('[int(v) for v in l]', setup)
116.25092001434314
>>> timeit.timeit('map(int, l)', setup)
106.66044823117454

Python 3 is over 4x faster by itself, but converting the map generator object to a list is still faster than comprehension, and creating the list by unpacking the map generator (thanks Artem!) is slightly faster still.

Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> setup = """import random
random.seed(10)
l = [str(random.randint(0, 99)) for i in range(100)]"""
>>> timeit.timeit('[int(v) for v in l]', setup)
25.133059591551955
>>> timeit.timeit('list(map(int, l))', setup)
19.705547827217515
>>> timeit.timeit('[*map(int, l)]', setup)
19.45838406513076

Note: In Python 3, 4 elements seems to be the crossover point (3 in Python 2) where comprehension is slightly faster, though unpacking the generator is still faster than either for lists with more than 1 element.

Here a minimal POC class w/ all the cruft removed

using System;
using System.ComponentModel;
using System.Runtime.InteropServices;

public class UncShareWithCredentials : IDisposable
{
    private string _uncShare;

    public UncShareWithCredentials(string uncShare, string userName, string password)
    {
        var nr = new Native.NETRESOURCE
        {
            dwType = Native.RESOURCETYPE_DISK,
            lpRemoteName = uncShare
        };

        int result = Native.WNetUseConnection(IntPtr.Zero, nr, password, userName, 0, null, null, null);
        if (result != Native.NO_ERROR)
        {
            throw new Win32Exception(result);
        }
        _uncShare = uncShare;
    }

    public void Dispose()
    {
        if (!string.IsNullOrEmpty(_uncShare))
        {
            Native.WNetCancelConnection2(_uncShare, Native.CONNECT_UPDATE_PROFILE, false);
            _uncShare = null;
        }
    }

    private class Native
    {
        public const int RESOURCETYPE_DISK = 0x00000001;
        public const int CONNECT_UPDATE_PROFILE = 0x00000001;
        public const int NO_ERROR = 0;

        [DllImport("mpr.dll")]
        public static extern int WNetUseConnection(IntPtr hwndOwner, NETRESOURCE lpNetResource, string lpPassword, string lpUserID,
            int dwFlags, string lpAccessName, string lpBufferSize, string lpResult);

        [DllImport("mpr.dll")]
        public static extern int WNetCancelConnection2(string lpName, int dwFlags, bool fForce);

        [StructLayout(LayoutKind.Sequential)]
        public class NETRESOURCE
        {
            public int dwScope;
            public int dwType;
            public int dwDisplayType;
            public int dwUsage;
            public string lpLocalName;
            public string lpRemoteName;
            public string lpComment;
            public string lpProvider;
        }
    }
}

You can directly use \\server\share\folder w/ WNetUseConnection, no need to strip it to \\server part only beforehand.

This works for me. Hope it will work for you too.

Update:

There is now a to_sql method, which is the preferred way to do this, rather than write_frame:

df.to_sql(con=con, name='table_name_for_df', if_exists='replace', flavor='mysql')

Also note: the syntax may change in pandas 0.14...

You can set up the connection with MySQLdb:

from pandas.io import sql
import MySQLdb

con = MySQLdb.connect()  # may need to add some other options to connect

Setting the flavor of write_frame to 'mysql' means you can write to mysql:

sql.write_frame(df, con=con, name='table_name_for_df', 
                if_exists='replace', flavor='mysql')

The argument if_exists tells pandas how to deal if the table already exists:

if_exists: {'fail', 'replace', 'append'}, default 'fail'
     fail: If table exists, do nothing.
     replace: If table exists, drop it, recreate it, and insert data.
     append: If table exists, insert data. Create if does not exist.

Although the write_frame docs currently suggest it only works on sqlite, mysql appears to be supported and in fact there is quite a bit of mysql testing in the codebase.

Because all attempts to print the argument I placed in my variable failed, here my 2 bytes for this question:

std::string dump_name;

(stuff..)

if(argc>2)
{
    dump_name.assign(argv[2]);
    fprintf(stdout, "ARGUMENT %s", dump_name.c_str());
}

Note the use of assign, and also the need for the c_str() function call.

I think you can use the overload of Regex.Replace to specify the maximum number of times to replace...

var regex = new Regex(Regex.Escape("o"));
var newText = regex.Replace("Hello World", "Foo", 1);

You need to make sure that a mac compatible version of java exists on your computer. Do java -version from terminal to check that. If not, download the apple jdk from the apple website. (Sun doesn't make one for apple themselves, IIRC.)

From there, follow the same command line instructions from compiling your program that you would use for java on any other platform.

It's possible that you still need to add the JDK into Eclipse (STS). Just because the JDK is on the system doesn't mean Eclipse knows where to find it.

Go to Preferences > Java > Installed JREs

If there is not an entry for the 1.7 JDK, add it. You'll have to point Eclipse to where you installed your 1.7 JDK.

If Eclipse can't find a JRE that is 1.7 compatible, I'm guessing that it just uses your default JRE, and that's probably still pointing at Java 1.6, which would be causing your red squiggly lines.

You could use a bit of workaround by placing a sass file in folder what you would like to import and import all files in that file like this:

file path:main/current/_current.scss

@import "placeholders"; @import "colors";

and in next dir level file you just use import for file what imported all files from that dir:

file path:main/main.scss

@import "EricMeyerResetCSSv20"; @import "clearfix"; @import "current";

That way you have same number of files, like you are importing the whole dir. Beware of order, file that comes last will override the matching stiles.

You can check the HTTP_USER_AGENT server variable. The user agent transfered by IE contains MSIE

if(strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false) { ... }

For specific versions you can extend your condition

if(strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE 6.') !== false) { ... }

Also see this related question.

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

http://plnkr.co/edit/k9qSx15fhSZRMwgAIMP4?p=preview

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

There is support for just this in the support library revision 23.3.0 (in the v4 which means compability back to Android 1.6).

In your Launcher activity, first call:

AppLaunchChecker.onActivityCreate(activity);

Then call:

AppLaunchChecker.hasStartedFromLauncher(activity);

Which will return if this was the first time the app was launched.

try this

#center_div
{
       margin: auto;
       position: absolute;
       top: 0; 
       left: 0;
       bottom: 0; 
       right: 0;
 }

Framework 4: no need to use StreamWriter:

System.IO.File.WriteAllLines("SavedLists.txt", Lists.verbList);

Basically, to make a cross domain AJAX requests, the requested server should allow the cross origin sharing of resources (CORS). You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/

In your scenario, you are setting the headers in the client which in fact needs to be set into http://localhost:8080/app server side code.

If you are using PHP Apache server, then you will need to add following in your .htaccess file:

Header set Access-Control-Allow-Origin "*"

Lots of choices here, but figured I'd toss mine on the heap. It is perl based, only targets variables of the form ${...}, takes the file to process as an argument and outputs the converted file on stdout:

use Env;
Env::import();

while(<>) { $_ =~ s/(\${\w+})/$1/eeg; $text .= $_; }

print "$text";

Of course I'm not really a perl person, so there could easily be a fatal flaw (works for me though).

It seems to me you are using the wrong version...

TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!

Arrays inherit equals() from Object and hence compare only returns true if comparing an array against itself.

On the other hand, Arrays.equals compares the elements of the arrays.

This snippet elucidates the difference:

Object o1 = new Object();
Object o2 = new Object();
Object[] a1 = { o1, o2 };
Object[] a2 = { o1, o2 };
System.out.println(a1.equals(a2)); // prints false
System.out.println(Arrays.equals(a1, a2)); // prints true

See also Arrays.equals(). Another static method there may also be of interest: Arrays.deepEquals().

SQL%ROWCOUNT can also be used without being assigned (at least from Oracle 11g).

As long as no operation (updates, deletes or inserts) has been performed within the current block, SQL%ROWCOUNT is set to null. Then it stays with the number of line affected by the last DML operation:

say we have table CLIENT

create table client (
  val_cli integer
 ,status varchar2(10)
)
/

We would test it this way:

begin
  dbms_output.put_line('Value when entering the block:'||sql%rowcount);

  insert into client 
            select 1, 'void' from dual
  union all select 4, 'void' from dual
  union all select 1, 'void' from dual
  union all select 6, 'void' from dual
  union all select 10, 'void' from dual;  
  dbms_output.put_line('Number of lines affected by previous DML operation:'||sql%rowcount);

  for val in 1..10
    loop
      update client set status = 'updated' where val_cli = val;
      if sql%rowcount = 0 then
        dbms_output.put_line('no client with '||val||' val_cli.');
      elsif sql%rowcount = 1 then
        dbms_output.put_line(sql%rowcount||' client updated for '||val);
      else -- >1
        dbms_output.put_line(sql%rowcount||' clients updated for '||val);
      end if;
  end loop;  
end;

Resulting in:

Value when entering the block:
Number of lines affected by previous DML operation:5
2 clients updated for 1
no client with 2 val_cli.
no client with 3 val_cli.
1 client updated for 4
no client with 5 val_cli.
1 client updated for 6
no client with 7 val_cli.
no client with 8 val_cli.
no client with 9 val_cli.
1 client updated for 10

Try do something like this (the problem was that you trying to use MyBook.Worksheets, but MyBook is not a Workbook object, but string, containing workbook name. I've added new varible Set WB = ActiveWorkbook, so you can use WB.Worksheets instead MyBook.Worksheets):

Sub NewWBandPasteSpecialALLSheets()
   MyBook = ActiveWorkbook.Name ' Get name of this book
   Workbooks.Add ' Open a new workbook
   NewBook = ActiveWorkbook.Name ' Save name of new book

   Workbooks(MyBook).Activate ' Back to original book

   Set WB = ActiveWorkbook

   Dim SH As Worksheet

   For Each SH In WB.Worksheets

       SH.Range("WholePrintArea").Copy

       Workbooks(NewBook).Activate

       With SH.Range("A1")
        .PasteSpecial (xlPasteColumnWidths)
        .PasteSpecial (xlFormats)
        .PasteSpecial (xlValues)

       End With

     Next

End Sub

But your code doesn't do what you want: it doesen't copy something to a new WB. So, the code below do it for you:

Sub NewWBandPasteSpecialALLSheets()
   Dim wb As Workbook
   Dim wbNew As Workbook
   Dim sh As Worksheet
   Dim shNew As Worksheet

   Set wb = ThisWorkbook
   Workbooks.Add ' Open a new workbook
   Set wbNew = ActiveWorkbook

   On Error Resume Next

   For Each sh In wb.Worksheets
      sh.Range("WholePrintArea").Copy

      'add new sheet into new workbook with the same name
      With wbNew.Worksheets

          Set shNew = Nothing
          Set shNew = .Item(sh.Name)

          If shNew Is Nothing Then
              .Add After:=.Item(.Count)
              .Item(.Count).Name = sh.Name
              Set shNew = .Item(.Count)
          End If
      End With

      With shNew.Range("A1")
          .PasteSpecial (xlPasteColumnWidths)
          .PasteSpecial (xlFormats)
          .PasteSpecial (xlValues)
      End With
   Next
End Sub

Take for example a framework or a library you're designing for other users, these users eventually will have a main function in their code in order to execute their app. If the user directly imports a sub-package of your library's project then the init of that sub-package will be called(once) first of all. The same for the root package of the library, etc...

There are many times when you may want a code block to be executed without the existence of a main func, directly or not.

If you, as the developer of the imaginary library, import your library's sub-package that has an init function, it will be called first and once, you don't have a main func but you need to make sure that some variables, or a table, will be initialized before the calls of other functions.

A good thing to remember and not to worry about, is that: the init always execute once per application.

init execution happens:

1. right before the init function of the "caller" package,
2. before the, optionally, main func,
3. but after the package-level variables, var = [...] or cost = [...],

When you import a package it will run all of its init functions, by order.

I'll will give a very good example of an init function. It will add mime types to a standard go's library named mime and a package-level function will use the mime standard package directly to get the custom mime types that are already be initialized at its init function:

package mime

import (
    "mime"
    "path/filepath"

Both values can be easily distinguished by using the strict comparison operator:

Working example at:

http://www.thesstech.com/tryme?filename=nullandundefined

Sample Code:

function compare(){
    var a = null; //variable assigned null value
    var b;  // undefined
    if (a === b){
        document.write("a and b have same datatype.");
    }
    else{
        document.write("a and b have different datatype.");
    }   
}

best to use crypt for password storing in DB

example code :

$crypted_pass = crypt($password);

//$pass_from_login is the user entered password
//$crypted_pass is the encryption
if(crypt($pass_from_login,$crypted_pass)) == $crypted_pass)
{
   echo("hello user!")
}

http://www.php.net/manual/en/function.crypt.php

Here's my approach: https://github.com/n0nSmoker/SQLAlchemy-serializer

pip install SQLAlchemy-serializer

You can easily add mixin to your model and than just call .to_dict() method on it's instance

You also can write your own mixin on base of SerializerMixin

Why not try to use the Babylonian method for finding a square root.

Here is my code for it:

double sqrt(double number)
{
    double error = 0.00001; //define the precision of your result
    double s = number;

    while ((s - number / s) > error) //loop until precision satisfied 
    {
        s = (s + number / s) / 2;
    }
    return s;
}

Good luck!

I am learning javascript and jquery and was going through all the answer, i faced same issue when calling javascript function for loading div element. I tried $('<divid>').ready(function(){alert('test'}) and it worked for me. I want to know is this good way to perform onload call on div element in the way i did using jquery selector.

thanks

It depends on which range you're talking about, but the dynamic range goes up to 65535 or 2^16-1 (16 bits).

http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

The Easiest way example to show you how to do that is :

Code :

>>> points = 19.5 >>> total = 22 >>>'Correct answers: {:.2%}'.format(points/total) `

Output : Correct answers: 88.64%

To change color of a cell:

$(document).on('click', '#table tbody td', function (event) {


    var selected = $(this).hasClass("obstacle");
    $("#table tbody td").removeClass("obstacle");
    if (!selected)
        $(this).addClass("obstacle");

});

This is how it worked for me (from above answers it was showing both default title and my custom view also).

ActionBar.LayoutParams layout = new ActionBar.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
// actionBar.setCustomView(view); //last view item must set to android:layout_alignParentRight="true" if few views are there 
actionBar.setCustomView(view, layout); // layout param width=fill/match parent
actionBar.setDisplayShowCustomEnabled(true);//must other wise its not showing custom view.

What I noticed is that both setCustomView(view) and setCustomView(view,params) the view width=match/fill parent. setDisplayShowCustomEnabled (boolean showCustom)

I like the solution provided by Henk Holterman. But to be a little more culture independent, you have to get the first day of the week for the current culture ( it's not always monday ):

using System.Globalization;

static DateTime FirstDateOfWeek(int year, int weekOfYear)
{
  DateTime jan1 = new DateTime(year, 1, 1);

  int daysOffset = (int)CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek - (int)jan1.DayOfWeek;

  DateTime firstMonday = jan1.AddDays(daysOffset);

  int firstWeek = CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(jan1, CultureInfo.CurrentCulture.DateTimeFormat.CalendarWeekRule, CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek);

  if (firstWeek <= 1)
  {
    weekOfYear -= 1;
  }

  return firstMonday.AddDays(weekOfYear * 7);
}

Integers are only 32 bits. This means that its max value is 2^31 -1. As you see, for very small numbers, you quickly have a result which can't be represented by an integer anymore. That's why Math.pow uses double.

If you want arbitrary integer precision, use BigInteger.pow. But it's of course less efficient.

Some times intermediates creates problem so delete it and Rebuild project

OR

simply run cmd command - > gradlew clean

in your project folder in work space (its work for me)

Here is how to create the desired outcome:

library(reshape2); library(tidyverse)
melt(outer(1:4, 1:4), varnames = c("X1", "X2")) %>%
ggplot() + 
  geom_tile(aes(X1, X2, fill = value)) + 
  scale_fill_continuous(guide = guide_legend()) +
  theme(legend.position="bottom",
        legend.spacing.x = unit(0, 'cm'))+
  guides(fill = guide_legend(label.position = "bottom"))

^{Created on 2019-12-07 by the reprex package (v0.3.0)}

Edit: no need for these imperfect options anymore, but I'm leaving them here for reference.

Two imperfect options that don't give you exactly what you were asking for, but pretty close (will at least put the colours together).

library(reshape2); library(tidyverse)
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
 theme(legend.position="bottom", legend.direction="vertical")

p1 + scale_fill_continuous(guide = "colorbar") + theme(legend.position="bottom")

^{Created on 2019-02-28 by the reprex package (v0.2.1)}

If you have an error somewhere deep in the code, then either throw an exception or set the error code. It's always better to throw an exception instead of setting error codes.

I know this thread is old, but this could be another solution:

var do_this = null;

function y(){
   // what you wanna do
}

do_this = setInterval(y, 1000);

function y_start(){
    do_this = setInterval(y, 1000);
};
function y_stop(){
    do_this = clearInterval(do_this);
};

For anyone stumbling across the same issue:

I fixed the problem by cloning the repo again at another location. I then copied my whole src dir (without .git dir obviously) from the corrupted repo into the freshly cloned repo. Thus I had all the recent changes and a clean and working repository.

I've had a play with this myself, and the best way I could find was to use a FrameLayout and lay a custom HorizontalScrollView (HSV) on top of the menu. Inside the HSV are your application Views, but there is a transparent View as the first child. This means, when the HSV has zero scroll offset, the menu will show through (and still be clickable surprisingly).

When the app starts up, we scroll the HSV to the offset of the first visible application View, and when we want to show the menu we scroll back to reveal the menu through the transparent View.

The code is here, and the bottom two buttons (called HorzScrollWithListMenu and HorzScrollWithImageMenu) in the Launch activity show the best menus I could come up with:

Android sliding menu demo

Screenshot from emulator (mid-scroll):

Screenshot from device (full-scroll). Note my icon is not as wide as the Facebook menu icon, so the menu view and 'app' view are not aligned.

Here is an example of iterating over a pd.DataFrame grouped by the column atable. For this sample, "create" statements for an SQL database are generated within the for loop:

import pandas as pd

df1 = pd.DataFrame({
    'atable':     ['Users', 'Users', 'Domains', 'Domains', 'Locks'],
    'column':     ['col_1', 'col_2', 'col_a', 'col_b', 'col'],
    'column_type':['varchar', 'varchar', 'int', 'varchar', 'varchar'],
    'is_null':    ['No', 'No', 'Yes', 'No', 'Yes'],
})

df1_grouped = df1.groupby('atable')

# iterate over each group
for group_name, df_group in df1_grouped:
    print('\nCREATE TABLE {}('.format(group_name))

    for row_index, row in df_group.iterrows():
        col = row['column']
        column_type = row['column_type']
        is_null = 'NOT NULL' if row['is_null'] == 'NO' else ''
        print('\t{} {} {},'.format(col, column_type, is_null))

    print(");")

I was looking for a way to do this in the terminal and filter lines in the normal "grep behaviour". Have your strings in a file strings.txt:

string1
string2
...

Then you can build a regular expression like (string1|string2|...) and use it for filtering:

cmd1 | grep -P "($(cat strings.txt | tr '\n' '|' | head -c -1))" | cmd2

Edit: Above only works if you don't use any regex characters, if escaping is required, it could be done like:

cat strings.txt | python3 -c "import re, sys; [sys.stdout.write(re.escape(line[:-1]) + '\n') for line in sys.stdin]" | ...

Just run cmd as admin. delete old node_modules folder and run npm install again.

public void Each<T>(IEnumerable<T> items, Action<T> action)
{
    foreach (var item in items)
        action(item);
}

... and call it thusly:

Each(myList, i => Console.WriteLine(i));

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

this worked for me :)

common_id not in (select ISNULL(common_id,'dummy-data') from Table1)

HTTP is a communications protocol that transports messages over a network. SOAP is a protocol to exchange XML-based messages that can use HTTP to transport those messages. Rest is a protocol to exchange any(XML or JSON) messages that can use HTTP to transport those messages.

The E stands for the exponent, and it is used to shorten long numbers. Since the input is a math input and exponents are in math to shorten great numbers, so that's why there is an E.

It is displayed like this: 4e.

Below is a working code to add a fragment e.g 3 times to a vertical LinearLayout (xNumberLinear). You can change number 3 with any other number or take a number from a spinner!

for (int i = 0; i < 3; i++) {
            LinearLayout linearDummy = new LinearLayout(getActivity());
            linearDummy.setOrientation(LinearLayout.VERTICAL);
            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {

                Toast.makeText(getActivity(), "This function works on newer versions of android", Toast.LENGTH_LONG).show();

            } else {
                linearDummy.setId(View.generateViewId());
            }
            fragmentManager.beginTransaction().add(linearDummy.getId(), new SomeFragment(),"someTag1").commit();

            xNumberLinear.addView(linearDummy);
        }

In the latest version (at least), you can find it through:

• Settings (menu)
• Preferences...
• MISC (tab)
• lower-left checkbox list
• "Auto-indent" is the 2nd option in this group

[EDIT] Though, I don't think it's had the best implementation of Auto-indent. So, check to make sure you have version 5.1 -- auto-indent got an overhaul recently, so it auto-corrects your indenting.

Do also note that you're missing the block for the 2nd if:

void main(){
  if(){
    if() { }  # here
  }
}

You can also pad the characters left by including a number following the X, such as this: string.format("0x{0:X8}", string_to_modify), which yields "0x00000C20".

You guys are going to laugh at this. I had an extra Listen 443 in ports.conf that shouldn't have been there. Removing that solved this.

'cacerts' is a truststore. A trust store is used to authenticate peers. A keystore is used to authenticate yourself.

I came across the same problem but, as stated above, the accepted solution did not work for me.

If you're inside a frame or iframe element, an alternative solution is to use

window.parent.$('#testdiv');

Here's a quick explanation of the differences between window.opener, window.parent and window.top:

• window.opener refers to the window that called window.open( ... ) to open the window from which it's called
• window.parent refers to the parent of a window in a frame or iframe element

Most of the MVC helper methods have a XXXFor variant. They are intended to be used in conjunction with a concrete model class. The idea is to allow the helper to derive the appropriate "name" attribute for the form-input control based on the property you specify in the lambda. This means that you get to eliminate "magic strings" that you would otherwise have to employ to correlate the model properties with your views. For example:

Html.Hidden("Name", "Value")

Will result in:

<input id="Name" name="Name" type="hidden" value="Value">

In your controller, you might have an action like:

[HttpPost]
public ActionResult MyAction(MyModel model) 
{
}

And a model like:

public class MyModel 
{
    public string Name { get; set; }
}

The raw Html.Hidden we used above will get correlated to the Name property in the model. However, it's somewhat distasteful that the value "Name" for the property must be specified using a string ("Name"). If you rename the Name property on the Model, your code will break and the error will be somewhat difficult to figure out. On the other hand, if you use HiddenFor, you get protected from that:

Html.HiddenFor(x => x.Name, "Value");

Now, if you rename the Name property, you will get an explicit runtime error indicating that the property can't be found. In addition, you get other benefits of static analysis, such as getting a drop-down of the members after typing x..

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

$( "#result" ).load( "ajax/test.html #container" );

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.

Good old readline();.

final float scale = getContext().getResources().getDisplayMetrics().density;
int pixels = (int) (dps * scale + 0.5f);

All scripts should be loaded last

In just about every case, it's best to place all your script references at the end of the page, just before </body>.

If you are unable to do so due to templating issues and whatnot, decorate your script tags with the defer attribute so that the browser knows to download your scripts after the HTML has been downloaded:

<script src="my.js" type="text/javascript" defer="defer"></script>

Edge cases

There are some edge cases, however, where you may experience page flickering or other artifacts during page load which can usually be solved by simply placing your jQuery script references in the <head> tag without the defer attribute. These cases include jQuery UI and other addons such as jCarousel or Treeview which modify the DOM as part of their functionality.

Further caveats

There are some libraries that must be loaded before the DOM or CSS, such as polyfills. Modernizr is one such library that must be placed in the head tag.

When the game starts:

long tStart = System.currentTimeMillis();

When the game ends:

long tEnd = System.currentTimeMillis();
long tDelta = tEnd - tStart;
double elapsedSeconds = tDelta / 1000.0;

You can solve the problem changing the compileSdkVersion in the Grandle.build file from 18 to wtever SDK is installed ..... BUTTTTT

1. If you are trying to goin back in SDK versions like 18 to 17 ,You can not use the feature available in 18 or 18+

2. If you are migrating your project (Eclipse to Android Studio ) Then off course you Don't have build.gradle file in your Existed Eclipse project

So, the only solution is to ensure the SDK version installed or not, you are targeting to , If not then install.

This is a solution based on extractors which will do the class cast:

assert( result == List(("English",true,2.5), ("Latin",false,0.9)))

At the start of the for loop I artificially wrap the result in a list so that it yields a list at the end. Then in the rest of the for loop I use the fact that generators (using <-) and value definitions (using =) will make use of the unapply methods.

(Older answer edited away - check edit history if you're curious)

Adding answer as this was the top hit when searching for "drop multiple columns in r":

The general version of the single column removal, e.g df$column1 <- NULL, is to use list(NULL):

df[ ,c('column1', 'column2')] <- list(NULL)

This also works for position index as well:

df[ ,c(1,2)] <- list(NULL)

This is a more general drop and as some comments have mentioned, removing by indices isn't recommended. Plus the familiar negative subset (used in other answers) doesn't work for columns given as strings:

> iris[ ,-c("Species")]
Error in -"Species" : invalid argument to unary operator

When the branch is no remote branch you can push your local branch direct to the remote.

git checkout master
git push origin master

or when you have a dev branch

git checkout dev
git push origin dev

or when the remote branch exists

git branch dev -t origin/dev

There are some other posibilites to push a remote branch.

If you just wanted to change the example and put the table at the top, then loc='top' in the table declaration is what you need,

the_table = ax.table(cellText=cell_text,
                      rowLabels=rows,
                      rowColours=colors,
                      colLabels=columns,
                      loc='top')

Then adjusting the plot with,

plt.subplots_adjust(left=0.2, top=0.8)

A more flexible option is to put the table in its own axis using subplots,

import numpy as np
import matplotlib.pyplot as plt


fig, axs =plt.subplots(2,1)
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs[0].axis('tight')
axs[0].axis('off')
the_table = axs[0].table(cellText=clust_data,colLabels=collabel,loc='center')

axs[1].plot(clust_data[:,0],clust_data[:,1])
plt.show()

which looks like this,

You are then free to adjust the locations of the axis as required.

The time() function displays the seconds between now and the unix epoch , 01 01 1970 (00:00:00 GMT). The strtotime() transforms a normal date format into a time() format. So the representation of that date into seconds will be : 1388516401

It worked to me. I'm still learning, and I've not figured it out yet why it is happening

For those of you who are using the Data Binding Library, to get the root of the current activity, simply use:

View rootView = dataBinding.getRoot();

And for Kotlin users, it's even simpler:

val rootView = dataBinding.root

Use this in Activity:

private Context context = this;

........
if(Utils.isInternetAvailable(context){
Utils.showToast(context, "toast");
}
..........

in Utils:

public class Utils {

    public static boolean isInternetAvailable(Context context) {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        return cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isConnected();
    }

}

It will be bigger in base64.

Base64 uses 6 bits per byte to encode data, whereas binary uses 8 bits per byte. Also, there is a little padding overhead with Base64. Not all bits are used with Base64 because it was developed in the first place to encode binary data on systems that can only correctly process non-binary data.

That means that the encoded image will be around 33%-36% larger (33% from not using 2 of the bits per byte, plus possible padding accounting for the remaining 3%).

A simple solution solved my problem. I just commented this line:

zend_extension = "d:/wamp/bin/php/php5.3.8/zend_ext/php_xdebug-2.1.2-5.3-vc9.dll

in my php.ini file. This extension was limiting the stack to 100 so I disabled it. The recursive function is now working as anticipated.

As kmcamara discovered, this is exactly the kind of problem that VLOOKUP is intended to solve, and using vlookup is arguably the simplest of the alternative ways to get the job done.

In addition to the three parameters for lookup_value, table_range to be searched, and the column_index for return values, VLOOKUP takes an optional fourth argument that the Excel documentation calls the "range_lookup".

Expanding on deathApril's explanation, if this argument is set to TRUE (or 1) or omitted, the table range must be sorted in ascending order of the values in the first column of the range for the function to return what would typically be understood to be the "correct" value. Under this default behavior, the function will return a value based upon an exact match, if one is found, or an approximate match if an exact match is not found.

If the match is approximate, the value that is returned by the function will be based on the next largest value that is less than the lookup_value. For example, if "12AT8003" were missing from the table in Sheet 1, the lookup formulas for that value in Sheet 2 would return '2', since "12AT8002" is the largest value in the lookup column of the table range that is less than "12AT8003". (VLOOKUP's default behavior makes perfect sense if, for example, the goal is to look up rates in a tax table.)

However, if the fourth argument is set to FALSE (or 0), VLOOKUP returns a looked-up value only if there is an exact match, and an error value of #N/A if there is not. It is now the usual practice to wrap an exact VLOOKUP in an IFERROR function in order to catch the no-match gracefully. Prior to the introduction of IFERROR, no matches were checked with an IF function using the VLOOKUP formula once to check whether there was a match, and once to return the actual match value.

Though initially harder to master, deusxmach1na's proposed solution is a variation on a powerful set of alternatives to VLOOKUP that can be used to return values for a column or list to the left of the lookup column, expanded to handle cases where an exact match on more than one criterion is needed, or modified to incorporate OR as well as AND match conditions among multiple criteria.

Repeating kcamara's chosen solution, the VLOOKUP formula for this problem would be:

   =VLOOKUP(A1,Sheet1!A$1:B$600,2,FALSE)

I think people here got sidetracked by the UrlEncode message. URLEncoding is not what you want -- you want to encode stuff that won't work as a filename on the target system.

Assuming that you want some generality -- feel free to find the illegal characters on several systems (MacOS, Windows, Linux and Unix), union them to form a set of characters to escape.

As for the escape, a HexEscape should be fine (Replacing the characters with %XX). Convert each character to UTF-8 bytes and encode everything >128 if you want to support systems that don't do unicode. But there are other ways, such as using back slashes "\" or HTML encoding """. You can create your own. All any system has to do is 'encode' the uncompatible character away. The above systems allow you to recreate the original name -- but something like replacing the bad chars with spaces works also.

On the same tangent as above, the only one to use is

Uri.EscapeDataString

-- It encodes everything that is needed for OAuth, it doesn't encode the things that OAuth forbids encoding, and encodes the space as %20 and not + (Also in the OATH Spec) See: RFC 3986. AFAIK, this is the latest URI spec.

Just another approach

function parseTimestamp(timestampStr) {_x000D_
  return new Date(new Date(timestampStr).getTime() + (new Date(timestampStr).getTimezoneOffset() * 60 * 1000));_x000D_
};_x000D_
_x000D_
//Sun Jan 01 2017 12:00:00_x000D_
var timestamp = 1483272000000;_x000D_
date = parseTimestamp(timestamp);_x000D_
document.write(date);

Cheers!

Query all users and filter by the list from your text file:

$Users = Get-Content 'C:\scripts\Users.txt'
Get-ADUser -Filter '*' -Properties DisplayName,Office |
    Where-Object { $Users -contains $_.SamAccountName } |
    Select-Object DisplayName, Office |
    Export-Csv 'C:\path\to\your.csv' -NoType

Get-ADUser -Filter '*' returns all AD user accounts. This stream of user objects is then piped into a Where-Object filter, which checks for each object if its SamAccountName property is contained in the user list from your input file ($Users). Only objects with a matching account name are passed forward to the next step of the pipeline. The output can be limited by selecting the relevant properties before exporting the data.

You can further optimize the code by replacing the -contains operator with hashtable lookups:

$Users = @{}
Get-Content 'C:\scripts\Users.txt' | ForEach-Object { $Users[$_] = $true }

Get-ADUser -Filter '*' -Properties DisplayName,Office |
    Where-Object { $Users.ContainsKey($_.SamAccountName) } |
    Select-Object DisplayName, Office |
    Export-Csv 'C:\path\to\your.csv' -NoType

You could also try 'upData' from 'Hmisc' package.

library(Hmisc)

trSamp = upData(trSamp, rename=c(sample.trainer.index..10000. = 'newname2'))

I was facing similar issue on my mac, and I found that docker wasn't running in my machine, I just went to applications and invoked whale and then it worked .

I keep this extension method around for this:

public static void Each<T>(this IEnumerable<T> ie, Action<T, int> action)
{
    var i = 0;
    foreach (var e in ie) action(e, i++);
}

And use it like so:

var strings = new List<string>();
strings.Each((str, n) =>
{
    // hooray
});

Or to allow for break-like behaviour:

public static bool Each<T>(this IEnumerable<T> ie, Func<T, int, bool> action)
{
    int i = 0;
    foreach (T e in ie) if (!action(e, i++)) return false;
    return true;
}

var strings = new List<string>() { "a", "b", "c" };

bool iteratedAll = strings.Each ((str, n)) =>
{
    if (str == "b") return false;
    return true;
});

Get a date object from the jquery date picker using

There seems no way to have google maps api key free without credit card. To test the functionality of google map you can use it while leaving the api key field "EMPTY". It will show a message saying "For Development Purpose Only". And that way you can test google map functionality without putting billing information for google map api key.

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

Update: ASP.NET Core does not have a SynchronizationContext. If you are on ASP.NET Core, it does not matter whether you use ConfigureAwait(false) or not.

For ASP.NET "Full" or "Classic" or whatever, the rest of this answer still applies.

Original post (for non-Core ASP.NET):

This video by the ASP.NET team has the best information on using async on ASP.NET.

I had read that it is more performant since it doesn't have to switch thread contexts back to the original thread context.

This is true with UI applications, where there is only one UI thread that you have to "sync" back to.

In ASP.NET, the situation is a bit more complex. When an async method resumes execution, it grabs a thread from the ASP.NET thread pool. If you disable the context capture using ConfigureAwait(false), then the thread just continues executing the method directly. If you do not disable the context capture, then the thread will re-enter the request context and then continue to execute the method.

So ConfigureAwait(false) does not save you a thread jump in ASP.NET; it does save you the re-entering of the request context, but this is normally very fast. ConfigureAwait(false) could be useful if you're trying to do a small amount of parallel processing of a request, but really TPL is a better fit for most of those scenarios.

However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function.

Actually, just doing an await can do that. Once your async method hits an await, the method is blocked but the thread returns to the thread pool. When the method is ready to continue, any thread is snatched from the thread pool and used to resume the method.

The only difference ConfigureAwait makes in ASP.NET is whether that thread enters the request context when resuming the method.

I have more background information in my MSDN article on SynchronizationContext and my async intro blog post.

For anyone having issues with Visual Studio 2019:

I had to first open menu Test ? Windows ? Test Explorer, and run the tests from there, before the option to Run / Debug tests would show up on the right click menu.

Almost everything in EC2 is multi-tenant. What the network performance indicates is what priority you will have compared with other instances sharing the same infrastructure.

If you need a guaranteed level of bandwidth, then EC2 will likely not work well for you.

The installation and usage is really simple and it has some cool plugins and interactive stuffs.

Yes its possible. Return a RedirectToAction() method like this:

As there's already an existing repository, running

git config --bool core.bare true

on the remote repository should suffice

From the core.bare documentation

If true (bare = true), the repository is assumed to be bare with no working directory associated. If this is the case a number of commands that require a working directory will be disabled, such as git-add or git-merge (but you will be able to push to it).

This setting is automatically guessed by git-clone or git-init when the repository is created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

Thanks to both Tony and Paul for the quick feedback, its very helpful. I actually figure out a solution through POJO. Here it is:

if (cell_value.indexOf("\"") != -1 || cell_value.indexOf(",") != -1) {
    cell_value = cell_value.replaceAll("\"", "\"\"");
    row.append("\"");
    row.append(cell_value);
    row.append("\"");
} else {
    row.append(cell_value);
}

in short if there is special character like comma or double quote within the string in side the cell, then first escape the double quote("\"") by adding additional double quote (like "\"\""), then put the whole thing into a double quote (like "\""+theWholeThing+"\"" )

Use an extension to UITableView to fetch the cell that contains any view:

@Paulw11's answer of setting up a custom cell type with a delegate property that sends messages to the table view is a good way to go, but it requires a certain amount of work to set up.

I think walking the table view cell's view hierarchy looking for the cell is a bad idea. It is fragile - if you later enclose your button in a view for layout purposes, that code is likely to break.

Using view tags is also fragile. You have to remember to set up the tags when you create the cell, and if you use that approach in a view controller that uses view tags for another purpose you can have duplicate tag numbers and your code can fail to work as expected.

I have created an extension to UITableView that lets you get the indexPath for any view that is contained in a table view cell. It returns an Optional that will be nil if the view passed in actually does not fall within a table view cell. Below is the extension source file in it's entirety. You can simply put this file in your project and then use the included indexPathForView(_:) method to find the indexPath that contains any view.

//
//  UITableView+indexPathForView.swift
//  TableViewExtension

import UIKit

public extension UITableView {
  
  /**
  This method returns the indexPath of the cell that contains the specified view
   
   - Parameter view: The view to find.
   
   - Returns: The indexPath of the cell containing the view, or nil if it can't be found
   
  */
  
    func indexPathForView(_ view: UIView) -> IndexPath? {
        let center = view.center
        let viewCenter = self.convert(center, from: view.superview)
        let indexPath = self.indexPathForRow(at: viewCenter)
        return indexPath
    }
}

To use it, you can simply call the method in the IBAction for a button that's contained in a cell:

func buttonTapped(_ button: UIButton) {
  if let indexPath = self.tableView.indexPathForView(button) {
    print("Button tapped at indexPath \(indexPath)")
  }
  else {
    print("Button indexPath not found")
  }
}

(Note that the indexPathForView(_:) function will only work if the view object it's passed is contained by a cell that's currently on-screen. That's reasonable, since a view that is not on-screen doesn't actually belong to a specific indexPath; it's likely to be assigned to a different indexPath when it's containing cell is recycled.)

EDIT:

You can download a working demo project that uses the above extension from Github: TableViewExtension.git

You can try this:

$('.show_hide').click(function () {
    $(".slidingDiv").toggle("'slide', {direction: 'right' }, 1000");
});

I think Adam was asking how to change umask value for all processes that tying to operate on /opt/lampp/htdocs directory.

The user file-creation mode mask (umask) is use to determine the file permission for newly created files. It can be used to control the default file permission for new files.

so if you will use some kind of ftp program to upload files into /opt/lampp/htdocs you need to configure your ftp server to use umask you want.

If files / directories be created for example by php, you need to modify php code

<?php
umask(0022);
// other code
?>

if you will create new files / folders from your bash session, you can set umask value in your shell profile ~/.bashrc Or you can set up umask in /etc/bashrc or /etc/profile file for all users. add the following to file: umask 022

Sample umask Values and File Creation Permissions
If umask value set to   User permission     Group permission     Others permission
000                         all              all                   all
007                         all              all                   none
027                         all          read / execute            none

And to change permissions for already created files you can use find. Hope this helps.

git clone -o <sha1-of-the-commit> <repository-url> <local-dir-name>

git uses the word origin in stead of popularly known revision

Following is a snippet from the manual $ git help clone

--origin <name>, -o <name>
    Instead of using the remote name origin to keep track of the upstream repository, use <name>.

This question has already received several good answers.

In summary, this technique is taking advantage of a feature of how the language is compiled. That is, JavaScript "short-circuits" the evaluation of Boolean operators and will return the value associated with either the first non-false variable value or whatever the last variable contains. See Anurag's explanation of those values that will evaluate to false.

Using this technique is not good practice for several reasons; however.

1. Code Readability: This is using Boolean operators, and if the behavior of how this compiles is not understood, then the expected result would be a Boolean value.

2. Stability: This is using a feature of how the language is compiled that is inconsistent across multiple languages, and due to this it is something that could potentially be targeted for change in the future.

3. Documented Features: There is an existing alternative that meets this need and is consistent across more languages. This would be the ternary operator:

   () ? value 1: Value 2.

Using the ternary operator does require a little more typing, but it clearly distinguishes between the Boolean expression being evaluated and the value being assigned. In addition it can be chained, so the types of default assignments being performed above could be recreated.

var a;
var b = null;
var c = undefined;
var d = 4;
var e = 'five';

var f =  ( a ) ? a : 
                ( b ) ? b :
                       ( c ) ? c :
                              ( d ) ? d :
                                      e;

alert(f); // 4

For me it was a permission problem.

enter:

mysqld --verbose --help | grep -A 1 "Default options"

[Warning] World-writable config file '/etc/mysql/my.cnf' is ignored.

So try to execute the following, and then restart the server

chmod 644 '/etc/mysql/my.cnf'

It will give mysql access to read and write to the file.

If i understand what you mean, you have to initialize your controller with that style. Something like:

myTVContoller = [[UITableViewController alloc] initWithStyle:UITableViewStyleGrouped];

It seems to work when I replace the

Runtime.getRuntime().exec("rmiregistry 2020");

by

LocateRegistry.createRegistry(2020);

anyone an idea why? What's the difference?

   If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
   following incantation to get a list of stashes that are still in your repository, but not reachable any more:

       git fsck --unreachable |
       grep commit | cut -d\  -f3 |
       xargs git log --merges --no-walk --grep=WIP

This helped me better than the accepted answer with the same scenario.

You can use composition instead... this will allow you to access class objects from the static type. But still cant implements interfaces or abstract classes

There is no way.

What I do is pass the UIViewController pointer to the UIView (or an appropriate inheritance). I'm sorry I can't help with the IB approach to the problem because I don't believe in IB.

To answer the first commenter: sometimes you do need to know who called you because it determines what you can do. For example with a database you might have read access only or read/write ...

The poor man's solution is to simply graph the lines x=0 and y=0. You can adjust the thickness and color of the lines to differentiate them from the graph.

Subquery giving dates. We are not linking with the model. So below query solves the problem.

If there are duplicate dates/model can be avoided by the following query.

select t.model, t.date
from doc t
inner join (select model, max(date) as MaxDate from doc  group by model)
tm on t.model = tm.model and t.date = tm.MaxDate

An element can have only one event handler attached per event type, but can have multiple event listeners.

So, how does it look in action?

Only the last event handler assigned gets run:

const btn = document.querySelector(".btn")
button.onclick = () => {
  console.log("Hello World");
};
button.onclick = () => {
  console.log("How are you?");
};
button.click() // "Hello World" 

All event listeners will be triggered:

const btn = document.querySelector(".btn")
button.addEventListener("click", event => {
  console.log("Hello World");
})
button.addEventListener("click", event => {
  console.log("How are you?");
})
button.click() 
// "Hello World"
// "How are you?"

IE Note: attachEvent is no longer supported. Starting with IE 11, use addEventListener: docs.

UPDATE myTable 
   SET myColumn = NULL 
 WHERE myCondition

I am just building on Abdennour TOUMI's answer. here are the reasons why:

1.) I agree with Brad, I do not think it is a good idea to extend object that we did not create.

2.) array.length is exactly reliable in javascript, I prefer Array.reduce beacuse a=[1,3];a[1000]=5; , now a.length would return 1001.

function getAverage(arry){
    // check if array
    if(!(Object.prototype.toString.call(arry) === '[object Array]')){
        return 0;
    }
    var sum = 0, count = 0; 
    sum = arry.reduce(function(previousValue, currentValue, index, array) {
        if(isFinite(currentValue)){
            count++;
            return previousValue+ parseFloat(currentValue);
        }
        return previousValue;
    }, sum);
    return count ? sum / count : 0; 
};

You can set one of the columns as an index in case it is an "id" for example. In this case the index column will be replaced by one of the columns you have chosen.

df.set_index('id', inplace=True)

free -h | awk '/Mem\:/ { print $2 }' 

This will provide you with the total memory in your system in human readable format and automatically scale to the appropriate unit ( e.g. bytes, KB, MB, or GB).

Here is my updated code. It works fine and it can help you.

The offending lines are the following:

MaxConnections=90
InitialConnections=80

You can increase the values to allow more connections.

You can use reflection (reflect.TypeOf()) to get the type of something, and the value it gives (Type) has a string representation (String method) that you can print.

In the package explorer, right-click on the package and select New -> File, then enter the filename including the ".properties" suffix.

Also making aware of interactions between clock() and usleep(). usleep() suspends the program, and clock() only measures the time the program is running.

If might be better off to use gettimeofday() as mentioned here

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

SQLSTATE[HY093]: Invalid parameter number: parameter was not defined

Unfortunately this error is not descriptive for a range of different problems related to the same issue - a binding error. It also does not specify where the error is, and so your problem is not necessarily in the execution, but the sql statement that was already 'prepared'.

These are the possible errors and their solutions:

1. There is a parameter mismatch - the number of fields does not match the parameters that have been bound. Watch out for arrays in arrays. To double check - use var_dump($var). "print_r" doesn't necessarily show you if the index in an array is another array (if the array has one value in it), whereas var_dump will.

2. You have tried to bind using the same binding value, for example: ":hash" and ":hash". Every index has to be unique, even if logically it makes sense to use the same for two different parts, even if it's the same value. (it's similar to a constant but more like a placeholder)

3. If you're binding more than one value in a statement (as is often the case with an "INSERT"), you need to bindParam and then bindValue to the parameters. The process here is to bind the parameters to the fields, and then bind the values to the parameters.

   // Code snippet
   $column_names = array();
   $stmt->bindParam(':'.$i, $column_names[$i], $param_type);
   $stmt->bindValue(':'.$i, $values[$i], $param_type);
   $i++;
   //.....
   

4. When binding values to column_names or table_names you can use `` but its not necessary, but make sure to be consistent.

5. Any value in '' single quotes is always treated as a string and will not be read as a column/table name or placeholder to bind to.

You can index Dictionary, you didn't need 'get'.

Dictionary<string,string> example = new Dictionary<string,string>();
...
example.Add("hello","world");
...
Console.Writeline(example["hello"]);

An efficient way to test/get values is TryGetValue (thanx to Earwicker):

if (otherExample.TryGetValue("key", out value))
{
    otherExample["key"] = value + 1;
}

With this method you can fast and exception-less get values (if present).

Resources:

Dictionary-Keys

Try Get Value

Use the default method in the interface and get the EntityManager to get the opportunity to set the ResultTransformer, then you can return the pure POJO, like this:

final String sql = "SELECT g.*, gm.* FROM group g LEFT JOIN group_members gm ON g.group_id = gm.group_id and gm.user_id = ? WHERE g.group_id = ?";
default GroupDetails getGroupDetails(Integer userId, Integer groupId) {
    return BaseRepository.getInstance().uniqueResult(sql, GroupDetails.class, userId, groupId);
}

And the BaseRepository.java is like this:

@PersistenceContext
public EntityManager em;

public <T> T uniqueResult(String sql, Class<T> dto, Object... params) {
    Session session = em.unwrap(Session.class);
    NativeQuery q = session.createSQLQuery(sql);
    if(params!=null){
        for(int i=0,len=params.length;i<len;i++){
            Object param=params[i];
            q.setParameter(i+1, param);
        }
    }
    q.setResultTransformer(Transformers.aliasToBean(dto));
    return (T) q.uniqueResult();
}

This solution does not impact any other methods in repository interface file.

In OS X 10.8.2, with Python 2.7:

/Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh

public int[] posStatus;       

public UsersInput()    
{    
    //It means postStatus will contain 9 elements from index 0 to 8. 
    this.posStatus = new int[9];   
}

int intUsersInput = 0;   

if (posStatus[intUsersInput-1] == 0) //if i input 9, it should go to 8?    
{    
    posStatus[intUsersInput-1] += 1; //set it to 1    
} 

2020 Update

JavaScript now has equivalents for both the Elvis Operator and the Safe Navigation Operator.

Safe Property Access

The optional chaining operator (?.) is currently a stage 4 ECMAScript proposal. You can use it today with Babel.

// `undefined` if either `a` or `b` are `null`/`undefined`. `a.b.c` otherwise.
const myVariable = a?.b?.c;

The logical AND operator (&&) is the "old", more-verbose way to handle this scenario.

const myVariable = a && a.b && a.b.c;

Providing a Default

The nullish coalescing operator (??) is currently a stage 4 ECMAScript proposal. You can use it today with Babel. It allows you to set a default value if the left-hand side of the operator is a nullary value (null/undefined).

const myVariable = a?.b?.c ?? 'Some other value';

// Evaluates to 'Some other value'
const myVariable2 = null ?? 'Some other value';

// Evaluates to ''
const myVariable3 = '' ?? 'Some other value';

The logical OR operator (||) is an alternative solution with slightly different behavior. It allows you to set a default value if the left-hand side of the operator is falsy. Note that the result of myVariable3 below differs from myVariable3 above.

const myVariable = a?.b?.c || 'Some other value';

// Evaluates to 'Some other value'
const myVariable2 = null || 'Some other value';

// Evaluates to 'Some other value'
const myVariable3 = '' || 'Some other value';

Adding nan to list, and the below works for me:

some_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456',np.nan]
any([i for i in [x for x in some_list if str(x) != 'nan'] if "abc" in i])

You can simply use the WebDriver object, and access to the page source code via its @property field page_source...

Try this code snippet :-)

from selenium import webdriver
driver = webdriver.Firefox('path/to/executable')
driver.get('https://some-domain.com')
source = driver.page_source
if 'stuff' in source:
    print('found...')
else:
    print('not in source...')

var maps_qty;
for (var i = 1; i <= maps_qty; i++)
    {
        $(".append_container").append('<div class="col-lg-10 grid_container_'+ (i) +'" >' + '<div id="googleMap'+ i +'" style="height:300px;"></div>'+'</div>');
        map = document.getElementById('googleMap' + i);
        initialize(map,i);
    }

// Intialize Google Map with Polyline Feature in it.

function initialize(map,i)
    {
        map_index = i-1;
        path_lat_long = [];
        var mapOptions = {
            zoom: 2,
            center: new google.maps.LatLng(51.508742,-0.120850)
        };

        var polyOptions = {
            strokeColor: '#000000',
            strokeOpacity: 1.0,
            strokeWeight: 3
        };

        //Push element(google map) in an array of google maps
        map_array.push(new google.maps.Map(map, mapOptions));
        //For Mapping polylines to MUltiple Google Maps
        polyline_array.push(new google.maps.Polyline(polyOptions));
        polyline_array[map_index].setMap(map_array[map_index]);
    }

// For Resizing Maps Multiple Maps.

google.maps.event.addListener(map, "idle", function()
    {
      google.maps.event.trigger(map, 'resize');
    });

map.setZoom( map.getZoom() - 1 );
map.setZoom( map.getZoom() + 1 );

df = df.merge(same.drop_duplicates(), on=['col1','col2'], 
               how='left', indicator=True)

df[df['_merge'] == 'left_only'].to_csv('output.csv')

View view =(View) getActivity().findViewById(controlId);
Spinner spinner = (Spinner)view.findViewById(R.id.spinner1);
String valToSet = spinner.getSelectedItem().toString();

You can use the following solution:

s="jack"

tup=tuple(s.split(" "))

output=('jack')

I ran into this problem debugging play framework version 2.x, turned out the server hadn't been started even though the play debug run command was issued. After a first request to the webserver which caused the play framework to really start the application at port 9000, I was able to connect properly to the debug port 9999 from eclipse.

[info] play - Application started (Dev)

The text above was shown in the console when the message above appeared, indicating why eclipse couldn't connect before first http request.

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

If it's just for "px" you can also use:

$(this).css('marginBottom').slice(0, -2);

Depending on the type of your variable, one of abs(int), labs(long), llabs(long long), imaxabs(intmax_t), fabsf(float), fabs(double), or fabsl(long double).

Those functions are all part of the C standard library, and so are present both in Objective-C and plain C (and are generally available in C++ programs too.)

(Alas, there is no habs(short) function. Or scabs(signed char) for that matter...)

Apple's and GNU's Objective-C headers also include an ABS() macro which is type-agnostic. I don't recommend using ABS() however as it is not guaranteed to be side-effect-safe. For instance, ABS(a++) will have an undefined result.

If you're using C++ or Objective-C++, you can bring in the <cmath> header and use std::abs(), which is templated for all the standard integer and floating-point types.

This works:

$category = $catrep->createQueryBuilder('cc')
        ->select('cc.categoryid')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->distinct()
        ->getQuery();

$categories = $category->getResult();

Edit for Symfony 3 & 4.

You should use ->groupBy('cc.categoryid') instead of ->distinct()

None of the answers are working for me on Windows 10, so here's what I use:

@echo off

set DNS1=8.8.8.8
set DNS2=8.8.4.4
set INTERFACE=Ethernet

netsh int ipv4 set dns name="%INTERFACE%" static %DNS1% primary validate=no
netsh int ipv4 add dns name="%INTERFACE%" %DNS2% index=2

ipconfig /flushdns

pause

This uses Google DNS. You can get interface name with the command netsh int show interface

In Java:

Transform your query in TypedQuery if it's a CriteriaQuery (javax.persistence).

Then:

query.unwrap(org.hibernate.Query.class).getQueryString();

round(value,significantDigit) is the ordinary solution, however this does not operate as one would expect from a math perspective when round values ending in 5. If the 5 is in the digit just after the one you're rounded to, these values are only sometimes rounded up as expected (i.e. 8.005 rounding to two decimal digits gives 8.01). For certain values due to the quirks of floating point math, they are rounded down instead!

i.e.

>>> round(1.0005,3)
1.0
>>> round(2.0005,3)
2.001
>>> round(3.0005,3)
3.001
>>> round(4.0005,3)
4.0
>>> round(1.005,2)
1.0
>>> round(5.005,2)
5.0
>>> round(6.005,2)
6.0
>>> round(7.005,2)
7.0
>>> round(3.005,2)
3.0
>>> round(8.005,2)
8.01

Weird.

Assuming your intent is to do the traditional rounding for statistics in the sciences, this is a handy wrapper to get the round function working as expected needing to import extra stuff like Decimal.

>>> round(0.075,2)

0.07

>>> round(0.075+10**(-2*5),2)

0.08

Aha! So based on this we can make a function...

def roundTraditional(val,digits):
   return round(val+10**(-len(str(val))-1), digits)

Basically this adds a value guaranteed to be smaller than the least given digit of the string you're trying to use round on. By adding that small quantity it preserve's round's behavior in most cases, while now ensuring if the digit inferior to the one being rounded to is 5 it rounds up, and if it is 4 it rounds down.

The approach of using 10**(-len(val)-1) was deliberate, as it the largest small number you can add to force the shift, while also ensuring that the value you add never changes the rounding even if the decimal . is missing. I could use just 10**(-len(val)) with a condiditional if (val>1) to subtract 1 more... but it's simpler to just always subtract the 1 as that won't change much the applicable range of decimal numbers this workaround can properly handle. This approach will fail if your values reaches the limits of the type, this will fail, but for nearly the entire range of valid decimal values it should work.

You can also use the decimal library to accomplish this, but the wrapper I propose is simpler and may be preferred in some cases.

Edit: Thanks Blckknght for pointing out that the 5 fringe case occurs only for certain values. Also an earlier version of this answer wasn't explicit enough that the odd rounding behavior occurs only when the digit immediately inferior to the digit you're rounding to has a 5.

For the impatient:

UPDATE target AS t
INNER JOIN (
  SELECT s.id, COUNT(*) AS count
  FROM source_grouped AS s
  -- WHERE s.custom_condition IS (true)
  GROUP BY s.id
) AS aggregate ON aggregate.id = t.id
SET t.count = aggregate.count

That's @mellamokb's answer, as above, reduced to the max.

try this out let me know what happens.

There are different regex engines but I think most of them will work with this:

apple|banana

If you are simply after a pretty solution and don't need to save a few nanoseconds, how about some LINQ sugar?

var input = "test1test2test3";
var replacements = new Dictionary<string, string> { { "1", "*" }, { "2", "_" }, { "3", "&" } };

var output = replacements.Aggregate(input, (current, replacement) => current.Replace(replacement.Key, replacement.Value));

You should check for !test, here is a fiddle showing that.

Timer timer = new Timer(3000, new ActionListener() {
  @Override
  public void actionPerformed(ActionEvent arg0) {
    // Code to be executed
  }
});
timer.setRepeats(false); // Only execute once
timer.start(); // Go go go!

This code will only be executed once, and the execution happens in 3000 ms (3 seconds).

As camickr mentions, you should lookup "How to Use Swing Timers" for a short introduction.

Assuming that you only have one pair of parenthesis.

string s = "User name (sales)";
int start = s.IndexOf("(") + 1;
int end = s.IndexOf(")", start);
string result = s.Substring(start, end - start);

The exact ranges for Chinese characters (except the extensions) are [\u2E80-\u2FD5\u3190-\u319f\u3400-\u4DBF\u4E00-\u9FCC\uF900-\uFAAD].

1. [\u2e80-\u2fd5]

CJK Radicals Supplement is a Unicode block containing alternative, often positional, forms of the Kangxi radicals. They are used headers in dictionary indices and other CJK ideograph collections organized by radical-stroke.

2. [\u3190-\u319f]

Kanbun is a Unicode block containing annotation characters used in Japanese copies of classical Chinese texts, to indicate reading order.

3. [\u3400-\u4DBF]

CJK Unified Ideographs Extension-A is a Unicode block containing rare Han ideographs.

4. [\u4E00-\u9FCC]

CJK Unified Ideographs is a Unicode block containing the most common CJK ideographs used in modern Chinese and Japanese.

5. [\uF900-\uFAAD]

CJK Compatibility Ideographs is a Unicode block created to contain Han characters that were encoded in multiple locations in other established character encodings, in addition to their CJK Unified Ideographs assignments, in order to retain round-trip compatibility between Unicode and those encodings.

For the details please refer to here, and the extensions are provided in other answers.

If you are using Spring 3, the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView showResults(final HttpServletRequest request, Principal principal) {

     final String currentUser = principal.getName();

 }
