Well to just to have some saying about semicolon. In lot of country, comma is what use for decimal not period. Mostly EU colonies, which consist of half of the world, another half follow UK standard (how the hell UK so big O_O) so in turn make using comma for database that include number create much of the headache because Excel refuse to recognize it as delimiter.

Like wise in my country, Viet Nam, follow France's standard, our partner HongKong use UK standard so comma make CSV unusable, and we use \t or ; instead for international use, but it still not "standard" per the document of CSV.

Another quick test for a string to have something in it but space.

if [[ -n "${str// /}" ]]; then
    echo "It is not empty!"
fi

"-n" means non-zero length string.

Then the first two slashes mean match all of the following, in our case space(s). Then the third slash is followed with the replacement (empty) string and closed with "}". Note the difference from the usual regular expression syntax.

You can read more about string manipulation in bash shell scripting here.

For PHP you can set

window > preferences > PHP > editor > mark occurrences 

Please check first checkbox (Mark occurrences of selected element in the current file)

And also check

Preferences > General > Editors > Text Editors > Annotations

'Occurrences' and 'Write Occurrences' with different style and color

I am a little late to party but you may want to consider using GetAwaiter.GetResult() to run your async code in sync context but as paralled as below;

 Parallel.ForEach(ids, i =>
{
    ICustomerRepo repo = new CustomerRepo();
    // Run this in thread which Parallel library occupied.
    var cust = repo.GetCustomer(i).GetAwaiter().GetResult();
    customers.Add(cust);
});

You didn't say what you're trying to do, but you hinted at it well enough in the comments to the other answer. I think you're probably looking for an auto increment column

create table logins (userid int auto_increment primary key, 
  username varchar(30), password varchar(30));

then no special code is needed on insert. Just

insert into logins (username, password) values ('user','pass');

The MySQL API has functions to tell you what userid was created when you execute this statement in client code.

If you are looking for answer in string values , try this

var check = moment('date/utc format');
day = check.format('dddd') // => ('Monday' , 'Tuesday' ----)
month = check.format('MMMM') // => ('January','February.....)
year = check.format('YYYY') // => ('2012','2013' ...)  

ALTER TABLE public.contract_termination_requests
ALTER COLUMN management_company_id DROP NOT NULL;

Another method is:

    function isFloat(float) {
        return /\./.test(float.toString());
    }

Might not be as efficient as the others but another method all the same.

Visual Studio 2017

1. Open Visual Studio
2. In Tools -> Extensions and Updates -> Online
3. Search for 'rdlc'
4. Install Microsoft Rdlc Report Designer (23.3 MB)
5. Close Visual Studio, let the installer run and open Visual Studio to see the rdlc in the designer.

I did not have the upstream branch on my local git. I had created a local branch from master, git checkout -b mybranch . I created a branch with bitbucket GUI on the upstream git and pushed my local branch (mybranch) to that upstream branch. Once I did a git fetch on my local git to retrieve the upstream branch, I could do a git branch -d mybranch.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

I had this problem when building FFMPEG static libraries (e.g. libavcodec.a) for Android x86_64 target platform (using Android NDK clang). When statically linking with my library the problem occured although all FFMPEG C -> object files (*.o) were compiled with -fPIC compile option:

x86_64/libavcodec.a(h264_qpel_10bit.o): 
requires dynamic R_X86_64_PC32 reloc against 'ff_pw_1023' 
which may overflow at runtime; recompile with -fPIC

The problem occured only for libavcodec.a and libswscale.a.

Source of this problem is that FFMPEG has assembler optimizations for x86* platforms e.g. the reported problem cause is in libavcodec/h264_qpel_10bit.asm -> h264_qpel_10bit.o.

When producing X86-64 bit static library (e.g. libavcodec.a) it looks like assembler files (e.g. libavcodec/h264_qpel_10bit.asm) uses some x86 (32bit) assembler commands which are incompatible when statically linking with x86-64 bit target library since they don't support required relocation type.

Possible solutions:

1. compile all ffmpeg files with no assembler optimizations (for ffmpeg this is configure option: --disable-asm)
2. produce dynamic libraries (e.g. libavcodec.so) and link them in your final library dynamically

I chose 1) and it solved the problem.

This pen I found the other day seemed to do it beautifully, just a bit of css and 21 lines of javascript. I hadn't heard of the cloneNode js command until I found this, but it totally worked for what I needed for sure.

http://codepen.io/rikschennink/pen/zvcgx

Detail: A. Basically it looks at your content div and invokes a cloneNode on it so it creates a duplicate which it then places inside the overflow:hidden header object sitting on top of the page. B. Then it simply listens for scrolling so that both images seem to match and blurs the header image... annnnd BAM. Effect achieved.

Not really fully do-able in CSS until they get the lil bit of scriptability built into the language.

I had a slightly augmented issue. I needed to rename a machine and then RE-JOIN a domain it was already a member of and could not find where to do that but its seems very close to what is here. The individual solutions above don't do it but with some togetherness... If you try to rename, you get denied. If you rename and then rejoin, you get an account already exists error. You need to bail from the domain by joining a workgroup and then you can run the rename and join in one command.

$Chops = Get-Credential 
# Or bring in a stored credential
$NewComputerName = "WhoImGonnaBe" 
# or value from CSV
$MyDomainName = "MyDomain"
Add-Computer -WorkgroupName NotADomain -force -DomainCredential $Chops
Add-Computer -DomainName $MyDomainName -Computername $ENV:Computername -NewName $NewComputerName -DomainCredential $Chops -Force -Restart
#  If running locally you really only need the -NewName and can omit the -Computername

Improving on this answer, I came up with these .gitconfig aliases:

branch-name = "symbolic-ref --short HEAD"
branch-remote-fetch = !"branch=$(git branch-name) && git config branch.\"$branch\".remote || echo origin #"
branch-remote-push  = !"branch=$(git branch-name) && git config branch.\"$branch\".pushRemote || git config remote.pushDefault || git branch-remote-fetch #"
branch-url-fetch = !"remote=$(git branch-remote-fetch) && git remote get-url        \"$remote\" #"  # cognizant of insteadOf
branch-url-push  = !"remote=$(git branch-remote-push ) && git remote get-url --push \"$remote\" #"  # cognizant of pushInsteadOf

The first time around, you allocate memory for Vector, which means the variables x,n.

However x doesn't yet point to anything useful.

So that is why second allocation is needed as well.

How about:

myString.Any(x => Char.IsWhiteSpace(x))

Or if you like using the "method group" syntax:

myString.Any(Char.IsWhiteSpace)

After some test, I found that for bootstrap modal need to wait for some time before executing the $(.modal).modal('hide') after executing $(.modal).modal('show'). And i found in my case i need at least 500 milisecond interval between the two.
So this is my test case and solution:

$('.modal-loading').modal('show');
setTimeout(function() {
  $('.modal-loading').modal('hide');
}, 500);

Slicing a list

top5 = array[:5]

• To slice a list, there's a simple syntax: array[start:stop:step]
• You can omit any parameter. These are all valid: array[start:], array[:stop], array[::step]

Slicing a generator

 import itertools
 top5 = itertools.islice(my_list, 5) # grab the first five elements

• You can't slice a generator directly in Python. itertools.islice() will wrap an object in a new slicing generator using the syntax itertools.islice(generator, start, stop, step)

• Remember, slicing a generator will exhaust it partially. If you want to keep the entire generator intact, perhaps turn it into a tuple or list first, like: result = tuple(generator)

In line with @Qwertie's suggestion, but going further on the lazy side, you could just pretend that each byte is a ISO-8859-1 character. For the uninitiated, ISO-8859-1 is a single-byte encoding that matches the first 256 code points of Unicode.

So @Ash's answer is actually redeemable with a charset:

byte[] args2 = getByteArry();
String byteStr = new String(args2, Charset.forName("ISO-8859-1"));

This encoding has the same readability as BAIS, with the advantage that it is processed faster than either BAIS or base64 as less branching is required. It might look like the JSON parser is doing a bit more, but it's fine because dealing with non-ASCII by escaping or by UTF-8 is part of a JSON parser's job anyways. It could map better to some formats like MessagePack with a profile.

Space-wise however, it is usually a loss, as nobody would be using UTF-16 for JSON. With UTF-8 each non-ASCII byte would occupy 2 bytes, while BAIS uses (2+4n + r?(r+1):0) bytes for every run of 3n+r such bytes (r is the remainder).

Just an additive.

I know this is old, but I wanted to add a solution I don't see that I came up with myself. Found this question while on hunt of a different solution and just figured, "Well, while I'm here."

First of all, Neal's answer is good and great to use after you run your loop, however, I'd prefer do all work at once. Of course, in my specific case I had to do more work than this simple example here, but the method still applies. I saw where a couple others suggested foreach loops, however, this still leaves you with after work due to the nature of the beast. Normally I suggest simpler things like foreach, however, in this case, it's best to remember good old fashioned for loop logic. Simply use i! To maintain appropriate index, just subtract from i after each removal of an Array item.

Here's my simple, working example:

$array = array(1,2,3,4,5);

for ($i = 0; $i < count($array); $i++) {
    if($array[$i] == 1 || $array[$i] == 2) {
        array_splice($array, $i, 1);
        $i--;
    }
}

Will output:

array(3) {
    [0]=> int(3)
    [1]=> int(4)
    [2]=> int(5)
}

This can have many simple implementations. For example, my exact case required holding of latest item in array based on multidimensional values. I'll show you what I mean:

$files = array(
    array(
        'name' => 'example.zip',
        'size' => '100000000',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example.zip',
        'size' => '10726556',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example.zip',
        'size' => '110726556',
        'type' => 'application/x-zip-compressed',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example2.zip',
        'size' => '12356556',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example2.zip',
        'deleteUrl' => 'server/php/?file=example2.zip',
        'deleteType' => 'DELETE'
    )
);

for ($i = 0; $i < count($files); $i++) {
    if ($i > 0) {
        if (is_array($files[$i-1])) {
            if (!key_exists('name', array_diff($files[$i], $files[$i-1]))) {
                if (!key_exists('url', $files[$i]) && key_exists('url', $files[$i-1])) $files[$i]['url'] = $files[$i-1]['url'];
                $i--;
                array_splice($files, $i, 1);
            }
        }
    }
}

Will output:

array(1) {
    [0]=> array(6) {
            ["name"]=> string(11) "example.zip"
            ["size"]=> string(9) "110726556"
            ["type"]=> string(28) "application/x-zip-compressed"
            ["deleteUrl"]=> string(28) "server/php/?file=example.zip"
            ["deleteType"]=> string(6) "DELETE"
            ["url"]=> string(44) "28188b90db990f5c5f75eb960a643b96/example.zip"
        }
    [1]=> array(6) {
            ["name"]=> string(11) "example2.zip"
            ["size"]=> string(9) "12356556"
            ["type"]=> string(28) "application/x-zip-compressed"
            ["deleteUrl"]=> string(28) "server/php/?file=example2.zip"
            ["deleteType"]=> string(6) "DELETE"
            ["url"]=> string(45) "28188b90db990f5c5f75eb960a643b96/example2.zip"
        }
}

As you see, I manipulate $i before the splice as I'm seeking to remove the previous, rather than the present item.

// on your branch that holds the commit you want to pass
$ git log
// copy the commit hash found
$ git checkout [branch that will copy the commit]
$ git reset --hard [hash of the commit you want to copy from the other branch]
// remove the [brackets]

Other more useful commands here with explanation: Git Guide

You could use a helper method to get rid of @SuppressWarnings("unchecked") all over a class.

@SuppressWarnings("unchecked")
private static <T> Class<T> generify(Class<?> cls) {
    return (Class<T>)cls;
}

Then you could write

Class<List<Foo>> cls = generify(List.class);

Other usage examples are

  Class<Map<String, Integer>> cls;

  cls = generify(Map.class);

  cls = TheClass.<Map<String, Integer>>generify(Map.class);

  funWithTypeParam(generify(Map.class));

public void funWithTypeParam(Class<Map<String, Integer>> cls) {
}

However, since it is rarely really useful, and the usage of the method defeats the compiler's type checking, I would not recommend to implement it in a place where it is publicly accessible.

You found the shorthand to set privileges for all existing tables in the given schema. The manual clarifies:

(but note that ALL TABLES is considered to include views and foreign tables).

Bold emphasis mine. serial columns are implemented with nextval() on a sequence as column default and, quoting the manual:

For sequences, this privilege allows the use of the currval and nextval functions.

So if there are serial columns, you'll also want to grant USAGE (or ALL PRIVILEGES) on sequences

GRANT USAGE ON ALL SEQUENCES IN SCHEMA foo TO mygrp;

Note: identity columns in Postgres 10 or later use implicit sequences that don't require additional privileges. (Consider upgrading serial columns.)

What about new objects?

You'll also be interested in DEFAULT PRIVILEGES for users or schemas:

ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT ALL PRIVILEGES ON TABLES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT USAGE          ON SEQUENCES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo REVOKE ...;

This sets privileges for objects created in the future automatically - but not for pre-existing objects.

Default privileges are only applied to objects created by the targeted user (FOR ROLE my_creating_role). If that clause is omitted, it defaults to the current user executing ALTER DEFAULT PRIVILEGES. To be explicit:

ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo GRANT ...;
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo REVOKE ...;

Note also that all versions of pgAdmin III have a subtle bug and display default privileges in the SQL pane, even if they do not apply to the current role. Be sure to adjust the FOR ROLE clause manually when copying the SQL script.

TL;DR Use Cmd/Ctrl+Shift+P then Package Control: Install Package, then Print to HTML and install it. Use Alt+Shift+P to print.

My favorite tool for printing from Sublime Text is Print to HTML package. You can "print" a selection or a whole file - via the web browser.

Usage

1. Make a selection (or none for the whole file)
2. Press Alt+Shift+P OR Shift+Command+P and type in "Print to HTML".

This opens your browser print dialog (Chrome for me) with the selected text neatly in the print dialog window and syntax highlighting intact. There you can choose a printer or export to PDF, and print.

Setup

Install the "Print to HTML" package using the package manager.

1. Ctrl + Shift + P => Gives a list of commands.
2. Find the package manager by typing "install"
3. You see a few choices. Select "Package Control: Install Package"
4. This opens a list of packages. Type "print to"
5. One of the choices should be "Print to HTML". Select that, and it is being installed.
6. You can use the "print to html" now by a keyboard shortcut Alt+Shift+P

def tuple_insert(tup,pos,ele):
    tup = tup[:pos]+(ele,)+tup[pos:]
    return tup

tuple_insert(tup,pos,9999)

tup: tuple
pos: Position to insert
ele: Element to insert

My solution is to have a general extension for string to int conversion.

extension String {

 // default: it is a number suitable for your project if the string is not an integer

    func toInt(default: Int) -> Int {
        if let result = Int(self) {
            return result
        }
        else {
            return default  
        }
    }

}

Are you keeping references to variables that you no longer need (e.g. data from the previous simulations)? If so, you have a memory leak. You just need to find where that is happening and make sure that you remove the references to the variables when they are no longer needed (this would automatically happen if they go out of scope).

If you actually need all that data from previous simulations in memory, you need to increase the heap size or change your algorithm.

You could create your key object something like this:

public class MapKey {

public  Object key1;
public Object key2;

public Object getKey1() {
    return key1;
}

public void setKey1(Object key1) {
    this.key1 = key1;
}

public Object getKey2() {
    return key2;
}

public void setKey2(Object key2) {
    this.key2 = key2;
}

public boolean equals(Object keyObject){

    if(keyObject==null)
        return false;

    if (keyObject.getClass()!= MapKey.class)
        return false;

    MapKey key = (MapKey)keyObject;

    if(key.key1!=null && this.key1==null)
        return false;

    if(key.key2 !=null && this.key2==null)
        return false;

    if(this.key1==null && key.key1 !=null)
        return false;

    if(this.key2==null && key.key2 !=null)
        return false;

    if(this.key1==null && key.key1==null && this.key2 !=null && key.key2 !=null)
        return this.key2.equals(key.key2);

    if(this.key2==null && key.key2==null && this.key1 !=null && key.key1 !=null)
        return this.key1.equals(key.key1);

    return (this.key1.equals(key.key1) && this.key2.equals(key2));
}

public int hashCode(){
    int key1HashCode=key1.hashCode();
    int key2HashCode=key2.hashCode();
    return key1HashCode >> 3 + key2HashCode << 5;
}

}

The advantage of this is: It will always make sure you are covering all the scenario's of Equals as well.

NOTE: Your key1 and key2 should be immutable. Only then will you be able to construct a stable key Object.

I believe the following is good enough for ruby code. I don't think I could write a unit test that shows any difference between this and the original.

Both top 2 answers doesn't work for me. So, here is my solution:

var timeout = null;

$('#myInput').keyup(function() {
    clearTimeout(timeout);

    timeout = setTimeout(function() {
        //do stuff here
    }, 500);
});

FAQ: ICON / SPLASH SCREEN (Cordova 5.x / 2015)

I present my answer as a general FAQ that may help you to solve many problems I've encountered while dealing with icons/splash screens. You may find out like me that the documentation is not always very clear nor up to date. This will probably go to StackOverflow documentation when available.

First: answering the question

How can I add custom app icons for iOS and Android with phonegap?

In your version of Cordova the icon tag is useless. It is not even documented in Cordova 3.0.0. You should use the documentation version that fits the cli you are using and not the latest one!

The icon tag does not work for Android at all before the version 3.5.0 according to what I can see in the different versions of the documentation. In 3.4.0 they still advice to manually copy the files

In newer versions: your config.xml looks better for newer Cordova versions. However there are still many things you may want to know. If you decide to upgrade here are some useful things to modify:

• You don't need the gap: namespace
• You need <preference name="SplashScreen" value="screen" /> for Android

Here are more details of the questions you might ask yourself when trying to deal with icons and splash screen:

Can I use an old version of Cordova / Phonegap

No, the icon/splashscreen feature was not in former versions of Cordova so you must use a recent version. In former versions, only Phonegap Build did handle the icons/splash screen so building locally and handling icons was only possible with a hook. I don't know the minimum version to use this feature but with 5.1.1 it works fine in both Cordova/Phonegap cli. With Cordova 3.5 it didn't work for me.

Edit: for Android you must use at least 3.5.0

How can I debug the build process about icons?

The cli use a CP command. If you provide an invalid icon path, it will show a cp error:

sebastien@sebastien-xps:cordova (dev *+$%)$ cordova run android --device
cp: no such file or directory: /home/sebastien/Desktop/Stample-react/cordova/res/www/stample_splash.png

Edit: you have use cordova build <platform> --verbose to get logs of cp command usage to see where your icons gets copied

The icons should go in a folder according to the config. For me it goes in many subfolders in : platforms/android/build/intermediates/res/armv7/debug/drawable-hdpi-v4/icon.png

Then you can find the APK, and open it as a zip archive to check the icons are present. They must be in a res/drawable* folder because it's a special folder for Android.

Where should I put the icons/splash screens in my project?

In many examples you will find the icons/splash screens are declared inside a res folder. This res is a special Android folder in the output APK, but it does not mean you have to use a res folder in your project.

You can put your icon anywhere, but the path you use must be relative to the root of the project, and not www so take care! This is documented, but not clearly because all the examples are using res and you don't know where this folder is :(

I mean if you put the icon in www/icon.png you absolutly must include www in your path.

Edit Mars 2016: after upgrading my versions, now it seems that icons are relative to www folder but documentation has not been changed (issue)

Does <icon src="icon.png"/> work?

No it does not!.

On Android, it seems it used to work before (when the density attribute was not supported yet?) but not anymore. See this Cordova issue

On iOS, it seems using this global declaration may override more specific declarations so take care and build with --verbose to ensure everything works as expected.

Can I use the same icon/splash screen file for all the densities.

Yes you can. You can even use the same file for both the icon, and splash screen (just to test!). I have used a "big" icon file of 65kb without any problem.

What's the difference when using the platform tag vs the platform attribute

<icon src="icon.png" platform="android" density="ldpi" />

is the same as

<platform name="android">
    <icon src="www/stample_icon.png" density="ldpi" />
</platform>

Should I use the gap: namespace if using Phonegap?

In my experience new versions of Phonegap or Cordova are both able to understand icon declarations without using any gap: xml namespace.

However I'm still waiting for a valid answer here: cordova/phonegap plugin add VS config.xml

As far as I understand, some features with the gap: namespace may be available earlier in PhonegapBuild, then in Phonegap and then being ported to Cordova (?)

Is <preference name="SplashScreen" value="screen" /> required?

At least for Android yes it is. I opened an issue with additional explainations.

Does icon declaration order matters?

Yes it does! It may not have any impact on Android but it has on iOS according to my tests. This is unexpected and undocumented behavior so I opened another issue.

Do I need cordova-plugin-splashscreen?

Yes this is absolutly required if you want the splash screen to work. The documentation is not clear (issue) and let us think that the plugin is required only to offer a splash screen javascript API.

How can I resize the images for all width/height/densities fastly

There are tools to help you do that. The best one for me is http://makeappicon.com/ but it requires to provide an email address.

Other possible solutions are:

• AndroidAssetStudio
• https://gist.github.com/LinusU/7515016
• cordova-icon

Can you give me an example config?

Yes. Here's my real config.xml

A good source of examples are starter kits. Like phonegap-start or Ionic starter

Sample DF:

In [79]: df = pd.DataFrame(np.random.randint(5, 15, (10, 3)), columns=list('abc'))

In [80]: df
Out[80]:
    a   b   c
0   6  11  11
1  14   7   8
2  13   5  11
3  13   7  11
4  13   5   9
5   5  11   9
6   9   8   6
7   5  11  10
8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

See an example here: http://www.cplusplus.com/reference/stl/vector/insert/ eg.:

...
vector::iterator iterator1;

  iterator1= vec1.begin();
  vec1.insert ( iterator1+i , vec2[i] );

// This means that at position "i" from the beginning it will insert the value from vec2 from position i

Your first approach was replacing the values from vec1[i] with the values from vec2[i]

You can use command line tool to build the release version. Next to your project folder, i.e.

$ ls
...
Foo.xcodeproj
...

Type the following build command:

$ xcodebuild -configuration Release

or if u want to use uniq:

<mycvs.cvs tr -s ',' ' ' | awk '{print $3" "$2" "$1}' | uniq -c -f2

gives:

Google gave me this answer as result, so...

I actually needed to "save" a string as an integer, for a binding between C and JavaScript, so I convert the string into a integer value:

/*
    Examples:
        int2str( str2int("test") ) == "test" // true
        int2str( str2int("t€st") ) // "t¬st", because "€".charCodeAt(0) is 8364, will be AND'ed with 0xff
    Limitations:
        max 4 chars, so it fits into an integer
*/
function str2int(the_str) {
    var ret = 0;
    var len = the_str.length;
    if (len >= 1) ret += (the_str.charCodeAt(0) & 0xff) <<  0;
    if (len >= 2) ret += (the_str.charCodeAt(1) & 0xff) <<  8;
    if (len >= 3) ret += (the_str.charCodeAt(2) & 0xff) << 16;
    if (len >= 4) ret += (the_str.charCodeAt(3) & 0xff) << 24;
    return ret;
}
function int2str(the_int) {
    var tmp = [
        (the_int & 0x000000ff) >>  0,
        (the_int & 0x0000ff00) >>  8,
        (the_int & 0x00ff0000) >> 16,
        (the_int & 0xff000000) >> 24
    ];
    var ret = "";
    for (var i=0; i<4; i++) {
        if (tmp[i] == 0)
            break;
        ret += String.fromCharCode(tmp[i]);
    }
    return ret;
}

We could call startActivityForResult() directly from Fragment So You should call this.startActivityForResult(i, 1); instead of getActivity().startActivityForResult(i, 1);

Intent i = new Intent(getActivity(), SecondActivity.class);
i.putExtra("helloString", helloString);
this.startActivityForResult(i, 1);

Activity will send the Activity Result to your Fragment.

The gem env lists where gems can be installed, but this can be 10 or more locations. If you want to know where a particular gem is installed, you can execute:

gem list -d <gemname>

To add the latest solution for 2021...

I found that the project nanoid provides unique string ids that can be used as key while also being fast and very small.

After installing using npm install nanoid, use as follows:

import { nanoid } from 'nanoid';

// Have the id associated with the data.
const todos = [{id: nanoid(), text: 'first todo'}];

// Then later, it can be rendered using a stable id as the key.
const todoItems = todos.map((todo) =>
  <li key={todo.id}>
    {todo.text}
  </li>
)

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

adding muted="muted" property to HTML5 tag solved my issue

Hmm... actually i dont know how this solved it? But the following steps solved it for me:

find / -name 'config.m4'

Now look if the config.m4 is anywhere in a folder of that stuff you want to phpize. Go to that folder and run phpize directly in there.

For Winforms

private void listBox1_DoubleClick(object sender, MouseEventArgs e)
    {
        int index = this.listBox1.IndexFromPoint(e.Location);
        if (index != System.Windows.Forms.ListBox.NoMatches)
        {
            MessageBox.Show(listBox1.SelectedItem.ToString());
        }
    }

and

public Form()
{
    InitializeComponent();
    listBox1.MouseDoubleClick += new MouseEventHandler(listBox1_DoubleClick);
}

that should also, prevent for the event firing if you select an item then click on a blank area.

I do it like this - from my point of view the easiest way:

set the form's 'StartPosition' to 'Manual', and add this to the form's designer:

Private Sub InitializeComponent()
.
.
.
Me.Location=New Point(-2000,-2000)
.
.
.
End Sub

Make sure that the location is set to something beyond or below the screen's dimensions. Later, when you want to show the form, set the Location to something within the screen's dimensions.

you can use an object

var days = {
   'Mon': 'Monday',
   'etc..': 'etc..',
   'Fri': 'Friday'
}

var date = new Date().toString().split(' ')[0]; //get day abreviation first
console.log(days[date]);

I was having the same issue, and I found out what was wrong. I had the HTML defined as

<form action="url" method="post">
    <input type="hidden" id="email" />
<form>
<script>
    function onsomeevent()
    {
       $("#email").val("[email protected]");
    }
</script>

Reading the form values on server always resulted in email as empty. After scratching my head (and numerous search), I realized the mistake was not defining the form/input correctly. On modifing the input (as shown next), it worked like a charm

<input type="hidden" id="email" name="email" />

Adding to this thread in case others have the same issue.

if(MyGuid!=Guild.Empty)

{

//Valid Guild

}

else {

// Invalid Guild

}

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

tar -zxf tmp.tar.gz -C ~/tmp1

I'd like to make the entire td a hyperlink. I'd prefer without javascript. Is this possible?

That's not possible without javascript. Also, that won't be semantic markup. You should use link instead otherwise it is a matter of attaching onclick handler to <td> to redirect to some other page.

If it's the last item in the array, you can do obj.pop()

simple solution:

public class long_length {
    long x,l=1,n;
    for (n=10;n<x;n*=10){
        if (x/n!=0){
            l++;
        }
    }
    System.out.print(l);
}

You can use that to create specific rules that meet GM standards.

I wanted to implement the datepicker to select the birthdate and I had troubles changing the yearRange as it doesn't seemed to work with my version (1.5). I updated to the newest jquery-ui datepicker version here: https://github.com/uxsolutions/bootstrap-datepicker.

Then I found out they provide this very helpful on-the-fly tool, so you can config your whole datepicker and see what settings you have to use.

That's how I found out that the option

defaultViewDate

is the option I was looking for and I didn't find any results searching the web.

So for other users: If you also want to provide the datepicker to change the birthdate, I suggest to use this code options:

$('#birthdate').datepicker({
    startView: 2,
    maxViewMode: 2,
    daysOfWeekHighlighted: "1,2",
    defaultViewDate: { year: new Date().getFullYear()-20, month: 01, day: 01 }
});

When opening the datepicker you will start with the view to select the years, 20 years ago relative to the current year.

As this is a High traffic post i hope to provide here an answer slightly more undetermined to the original question and thus to provide further background on a JSON Hijacking attack and its consequences

JSON Hijacking as the name suggests is an attack similar to Cross-Site Request Forgery where an attacker can access cross-domain sensitive JSON data from applications that return sensitive data as array literals to GET requests. An example of a JSON call returning an array literal is shown below:

[{"id":"1001","ccnum":"4111111111111111","balance":"2345.15"}, 
{"id":"1002","ccnum":"5555555555554444","balance":"10345.00"}, 
{"id":"1003","ccnum":"5105105105105100","balance":"6250.50"}]

This attack can be achieved in 3 major steps:

Step 1: Get an authenticated user to visit a malicious page. Step 2: The malicious page will try and access sensitive data from the application that the user is logged into.This can be done by embedding a script tag in an HTML page since the same-origin policy does not apply to script tags.

<script src="http://<jsonsite>/json_server.php"></script>

The browser will make a GET request to json_server.php and any authentication cookies of the user will be sent along with the request. Step 3: At this point while the malicious site has executed the script it does not have access to any sensitive data. Getting access to the data can be achieved by using an object prototype setter. In the code below an object prototypes property is being bound to the defined function when an attempt is being made to set the "ccnum" property.

Object.prototype.__defineSetter__('ccnum',function(obj){

secrets =secrets.concat(" ", obj);

});

At this point the malicious site has successfully hijacked the sensitive financial data (ccnum) returned byjson_server.php JSON

It should be noted that not all browsers support this method; the proof of concept was done on Firefox 3.x.This method has now been deprecated and replaced by the useObject.defineProperty There is also a variation of this attack that should work on all browsers where full named JavaScript (e.g. pi=3.14159) is returned instead of a JSON array.

There are several ways in which JSON Hijacking can be prevented:

• Since SCRIPT tags can only generate HTTP GET requests, only return JSON objects to POST requests.

• Prevent the web browser from interpreting the JSON object as valid JavaScript code.

• Implement Cross-Site Request Forgery protection by requiring that a predefined random value be required for all JSON requests.

so as you can see While(1) comes under the last option. In the most simple terms, while(1) is an infinite loop which will run till a break statement is issued explicitly. And thus what would be described as a lock for the key to be applied (google break statement). Therefore a JSON hijacking, in which the Hacker has no key will be consistently dismissed.Alas, If you read the JSON block with a parser, the while(1) loop is ignored.

So in conclusion, the while(1) loop can more easily visualised as a simple break statement cipher that google can use to control flow of data.

However the key word in that statement is the word 'simple'. The usage of authenticated infinite loops has been thankfully removed from basic practice in the years since 2010 due to its absolute decimation of CPU usage when isolated (and the fact the internet has moved away from forcing through crude 'quick-fixes'). Today instead the codebase has preventative measures embedded and the system is not crucial nor effective anymore. (part of this is the move away from JSON Hijacking to more fruitful datafarming techniques that i wont go into at present)

additionally to sangam code

if (chNode["innerNode"]["innermostNode"]==null)
            return true; //node    *parentNode*/innerNode/innermostNode exists

Much simpler to my opinion:

sed -r 's/\s+//g' filename

Try something like:

 SELECT id, NewsHeadline as news_headline, NewsText as news_text, state CreatedDate as created_on
 FROM News 
 WHERE CreatedDate >= DATEADD(day,-7, GETDATE())

A Context represents your environment. It represents the state surrounding where you are in your system.

For example, in web programming in Java, you have a Request, and a Response. These are passed to the service method of a Servlet.

A property of the Servlet is the ServletConfig, and within that is a ServletContext.

The ServletContext is used to tell the servlet about the Container that the Servlet is within.

So, the ServletContext represents the servlets environment within its container.

Similarly, in Java EE, you have EBJContexts that elements (like session beans) can access to work with their containers.

Those are two examples of contexts used in Java today.

Edit --

You mention Android.

Look here: http://developer.android.com/reference/android/content/Context.html

You can see how this Context gives you all sorts of information about where the Android app is deployed and what's available to it.

result_array() is faster, result() is easier

Did you try putting all your jars directly in the WEB-INF/lib dir instead of sub-dirs of that?

No WEB-INF/lib/spring/org.springframework.aop-3.0.0.RELEASE.jar, just WEB-INF/lib/org.springframework.aop-3.0.0.RELEASE.jar

Same with the rest of the jars.

Just got a solution to get height and width of a custom view:

@Override
protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld){
    super.onSizeChanged(xNew, yNew, xOld, yOld);

    viewWidth = xNew;
    viewHeight = yNew;
}

Its working in my case.

I've been able to input values within the character ":

db_user="postgresql"
db_passwd="this,is,my,password"

Slightly modifying answer by @Yogeesh Seralathan. His answer works perfectly, just run these commands at once.

adb shell input keyevent 26 && adb shell input touchscreen swipe 930 880 930 380 && adb shell input text XXXX && adb shell input keyevent 66

Experienced the same error, below is the reason and solution that worked for me for mysql-5.7.14-winx64

reason: DATA folder to have some default folders and files which were missing

solution: delete everything from DATA folder, i assume its a fresh installation so backup anything that you need if at all. Then run this from the command prompt and it will create required files and folders "mysqld --initialize --console" now run "mysqld" and it should work well.

I'm a new user for Spring. I found a different solution for this. Using reflection and making public necessary fields and assign mock objects.

This is my auth controller and it has some Autowired private properties.

        User user = usersDao.getLoginUser(username, password);

        if (user == null)
            return new ErrorResult("Kullaniciadi veya sifre hatali");

        Token token = new Token();
        token.setTokenId("aergaerg");
        token.setUserId(1);
        token.setInsertDatetime(new Date());
        return token;
    }
}

And this is my Junit test for AuthController. I'm making public needed private properties and assign mock objects to them and rock :)

public class AuthControllerTest {

    @Test
    public void getToken() {
        try {
            UsersDAO mockUsersDao = mock(UsersDAO.class);
            TokensDAO mockTokensDao = mock(TokensDAO.class);

            User dummyUser = new User();
            dummyUser.setId(10);
            dummyUser.setUsername("nixarsoft");
            dummyUser.setTopId(0);

            when(mockUsersDao.getLoginUser(Matchers.anyString(), Matchers.anyString())) //
                    .thenReturn(dummyUser);

            AuthController ctrl = new AuthController();

            Field usersDaoField = ctrl.getClass().getDeclaredField("usersDao");
            usersDaoField.setAccessible(true);
            usersDaoField.set(ctrl, mockUsersDao);

            Field tokensDaoField = ctrl.getClass().getDeclaredField("tokensDao");
            tokensDaoField.setAccessible(true);
            tokensDaoField.set(ctrl, mockTokensDao);

            Token t = (Token) ctrl.getToken("test", "aergaeg");

            Assert.assertNotNull(t);

        } catch (Exception ex) {
            System.out.println(ex);
        }
    }

}

I don't know advantages and disadvantages for this way but this is working. This technic has a little bit more code but these codes can be seperated by different methods etc. There are more good answers for this question but I want to point to different solution. Sorry for my bad english. Have a good java to everybody :)

In your example

product.valid?

Is actually a function call and calls a function named valid?. Certain types of "test for condition"/boolean functions have a question mark as part of the function name by convention.

I generally find that when SSIS seems to be irrationally complaining about an apparently good connection, it is because I am trying to define the Connection directly using a package variable rather than via a Connection Manager. Example: today I had a Web Service Task where I made the mistake of directly creating an Expression defining its "Connection" property in terms of a package variable that contained the URL of the web service. Note however that a Connection is not the same thing as a ConnectionString! So when I looked at the task, it looked for all the world like it had everything valid, because it displayed a perfectly valid URL as the "Connection". The problem is that the Connection cannot be a string; it must be a Connection Manager.

Just create another form (let's call it formPopup) using Visual Studio. In a button handler write the following code:

var formPopup = new Form();
formPopup.Show(this); // if you need non-modal window

If you need a non-modal window use: formPopup.Show();. If you need a dialog (so your code will hang on this invocation until you close the opened form) use: formPopup.ShowDialog()

Actually, your topic is belongs on https://serverfault.com/ but you can still try to check these .htaccess directives:

RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule ^(.*) https://%{HTTP_HOST}/$1

System.ArgumentNullException: Value cannot be null. Parameter name: value

This error message is not very helpful!

You can get this error in many different ways. The error may not always be with the parameter name: value. It could be whatever parameter name is being passed into a function.

As a generic way to solve this, look at the stack trace or call stack:

Test method GetApiModel threw exception: 
System.ArgumentNullException: Value cannot be null.
Parameter name: value
    at Newtonsoft.Json.JsonConvert.DeserializeObject(String value, Type type, JsonSerializerSettings settings)

You can see that the parameter name value is the first parameter for DeserializeObject. This lead me to check my AutoMapper mapping where we are deserializing a JSON string. That string is null in my database.

You can change the code to check for null.

Maybe Series would provide all the functions you need:

pd.Series({'A':a,'B':b})

DataFrame can be thought of as a collection of Series hence you can :

• Concatenate multiple Series into one data frame (as described here )

• Add a Series variable into existing data frame ( example here )

pluck(column_name)

This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.

Examples:

Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)

see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck

Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns

To see both the normal distribution and your actual data you should plot your data as a histogram, then draw the probability density function over this. See the example on https://docs.scipy.org/doc/numpy-1.15.0/reference/generated/numpy.random.normal.html for exactly how to do this.

You can use this Function if you have some variable in the SSIS.

    Package pkg;

    Microsoft.SqlServer.Dts.Runtime.Application app;
    DTSExecResult pkgResults;
    Variables vars;

    app = new Microsoft.SqlServer.Dts.Runtime.Application();
    pkg = app.LoadPackage(" Location of your SSIS package", null);

    vars = pkg.Variables;

    // your variables
    vars["somevariable1"].Value = "yourvariable1";
    vars["somevariable2"].Value = "yourvariable2";

    pkgResults = pkg.Execute(null, vars, null, null, null);

    if (pkgResults == DTSExecResult.Success)
    {
        Console.WriteLine("Package ran successfully");
    }
    else
    {

        Console.WriteLine("Package failed");
    }

Or by using DBIs sqlRownamesToColumn

library(DBI)
sqlRownamesToColumn(df)

I'm using Mac OS and to write multiple lines in a SH Script following code worked for me

#! /bin/bash
FILE_NAME="SomeRandomFile"

touch $FILE_NAME

echo """I wrote all
the  
stuff
here.
And to access a variable we can use
$FILE_NAME  

""" >> $FILE_NAME

cat $FILE_NAME

Please don't forget to assign chmod as required to the script file. I have used

chmod u+x myScriptFile.sh

Since char is a primitive type, you can just write c == ' '.
You only need to call equals() for reference types like String or Character.

You are using incorrect overload. You should use this overload

public static MvcHtmlString ActionLink(
    this HtmlHelper htmlHelper,
    string linkText,
    string actionName,
    string controllerName,
    Object routeValues,
    Object htmlAttributes
) 

And the correct code would be

<%= Html.ActionLink("Create New Part", "CreateParts", "PartList", new { parentPartId = 0 }, null)%>

Note that extra parameter at the end. For the other overloads, visit LinkExtensions.ActionLink Method. As you can see there is no string, string, string, object overload that you are trying to use.

As @weichsel stated, CGFloat is just a typedef for either float or double. You can see for yourself by Command-double-clicking on "CGFloat" in Xcode — it will jump to the CGBase.h header where the typedef is defined. The same approach is used for NSInteger and NSUInteger as well.

These types were introduced to make it easier to write code that works on both 32-bit and 64-bit without modification. However, if all you need is float precision within your own code, you can still use float if you like — it will reduce your memory footprint somewhat. Same goes for integer values.

I suggest you invest the modest time required to make your app 64-bit clean and try running it as such, since most Macs now have 64-bit CPUs and Snow Leopard is fully 64-bit, including the kernel and user applications. Apple's 64-bit Transition Guide for Cocoa is a useful resource.

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

You can read more about this in the Gotchas.

Try float property. Here's an example: http://jsfiddle.net/mLmHR/

You overlooked one method: isBeingPresented.

isBeingPresented is true when the view controller is being presented and false when being pushed.

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    if ([self isBeingPresented]) {
        // being presented
    } else if ([self isMovingToParentViewController]) {
        // being pushed
    } else {
        // simply showing again because another VC was dismissed
    }
}

The InnoDB engine does not store deleted data. As you insert and delete rows, unused space is left allocated within the InnoDB storage files. Over time, the overall space will not decrease, but over time the 'deleted and freed' space will be automatically reused by the DB server.

You can further tune and manage the space used by the engine through an manual re-org of the tables. To do this, dump the data in the affected tables using mysqldump, drop the tables, restart the mysql service, and then recreate the tables from the dump files.

This is my take on it:

public enum LoginState { 
    LOGGED_IN(1), LOGGED_OUT(0), IN_TRANSACTION(-1);

    private int code;

    LoginState(int code) {
        this.code = code;
    }

    public int getCode() {
        return code;
    }

    public static LoginState getLoginStateFromCode(int code){
        for(LoginState e : LoginState.values()){
            if(code == e.code) return e;
        }
        return LoginState.LOGGED_OUT; //or null
    }
};

And I have used it with System Preferences in Android like so:

LoginState getLoginState(int i) {
    return LoginState.getLoginStateFromCode(
                prefs().getInt(SPK_IS_LOGIN, LoginState.LOGGED_OUT.getCode())
            );
}

public static void setLoginState(LoginState newLoginState) {
    editor().putInt(SPK_IS_LOGIN, newLoginState.getCode());
    editor().commit();
}

where pref and editor are SharedPreferences and a SharedPreferences.Editor

There is another way, take this as example

Dim sr As String    
sr = "6:10"
Rows(sr).Select

All you need to do is to convert your variables iStartRow, iEndRow to a string.

According to the Web API documentation page JSON and XML Serialization in ASP.NET Web API to explicitly prevent serialization on a property you can either use [JsonIgnore] for the Json serializer or [IgnoreDataMember] for the default XML serializer.

However in testing I have noticed that [IgnoreDataMember] prevents serialization for both XML and Json requests, so I would recommend using that rather than decorating a property with multiple attributes.

StreamWriter is available for NET 1.1. and for the Compact framework. Just open the file and apply the ToString to your StringBuilder:

    StringBuilder sb = new StringBuilder();
    sb.Append(......);

    StreamWriter sw = new StreamWriter("\\hereIAm.txt", true);
    sw.Write(sb.ToString());
    sw.Close();

Also, note that you say that you want to append debug messages to the file (like a log). In this case, the correct constructor for StreamWriter is the one that accepts an append boolean flag. If true then it tries to append to an existing file or create a new one if it doesn't exists.

git archive also works with remote repository.

git archive --format=tar \
--remote=ssh://remote_server/remote_repository master | tar -xf -

To export particular path inside the repo add as many paths as you wish as last argument to git, e.g.:

git archive --format=tar \
--remote=ssh://remote_server/remote_repository master path1/ path2/ | tar -xv

You can think of Python global variables as "module" variables - and as such they are much more useful than the traditional "global variables" from C.

A global variable is actually defined in a module's __dict__ and can be accessed from outside that module as a module attribute.

So, in your example:

# ../myproject/main.py

# Define global myList
# global myList  - there is no "global" declaration at module level. Just inside
# function and methods
myList = []

# Imports
import subfile

# Do something
subfile.stuff()
print(myList[0])

And:

# ../myproject/subfile.py

# Save "hey" into myList
def stuff():
     # You have to make the module main available for the 
     # code here.
     # Placing the import inside the function body will
     # usually avoid import cycles - 
     # unless you happen to call this function from 
     # either main or subfile's body (i.e. not from inside a function or method)
     import main
     main.mylist.append("hey")

Along the same lines as SCFrench's answer, but with a more C# style spin..

I would (and often do) make a class containing multiple static methods. For example:

classdef Statistics

    methods(Static)
        function val = MyMean(data)
            val = mean(data);
        end

        function val = MyStd(data)
            val = std(data);
        end
    end

end

As the methods are static you don't need to instansiate the class. You call the functions as follows:

data = 1:10;

mean = Statistics.MyMean(data);
std = Statistics.MyStd(data);     

PHP.net explanation about MAX_FILE_SIZE hidden field.

The MAX_FILE_SIZE hidden field (measured in bytes) must precede the file input field, and its value is the maximum filesize accepted by PHP. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too large and the transfer failed. Keep in mind: fooling this setting on the browser side is quite easy, so never rely on files with a greater size being blocked by this feature. It is merely a convenience feature for users on the client side of the application. The PHP settings (on the server side) for maximum-size, however, cannot be fooled.

http://php.net/manual/en/features.file-upload.post-method.php

I was also trying to join my path using path.join(__dirname, 'access.log') but it was throwing the same error.

Here is how I fixed it:

I first imported the path package and declared a variable named __dirname, then called the resolve path method.

In CommonJS

var path = require("path");

var __dirname = path.resolve();

In ES6+

import path  from 'path';

const __dirname = path.resolve();

Happy coding.......

If you have a good reason to do that, this will do the trick

add these targets:

[button addTarget:self action:@selector(buttonTouchDown:) forControlEvents:UIControlEventTouchDown];
[button addTarget:self action:@selector(buttonTouchUp:) forControlEvents:UIControlEventTouchUpInside];


-(void)buttonTouchDown:(id)sender{
    UIButton *button=(UIButton *)sender;
    if(button.selected){
        [button setImage:[UIImage imageNamed:@"pressed.png"] forState:UIControlStateNormal];
    }
}

-(void)buttonTouchUp:(id)sender{
    UIButton *button=(UIButton *)sender;
    [button setImage:[UIImage imageNamed:@"normal.png"] forState:UIControlStateNormal];
}

The only way you should be getting values "out of" an Observable/Subject is with subscribe!

If you're using getValue() you're doing something imperative in declarative paradigm. It's there as an escape hatch, but 99.9% of the time you should NOT use getValue(). There are a few interesting things that getValue() will do: It will throw an error if the subject has been unsubscribed, it will prevent you from getting a value if the subject is dead because it's errored, etc. But, again, it's there as an escape hatch for rare circumstances.

There are several ways of getting the latest value from a Subject or Observable in a "Rx-y" way:

1. Using BehaviorSubject: But actually subscribing to it. When you first subscribe to BehaviorSubject it will synchronously send the previous value it received or was initialized with.
2. Using a ReplaySubject(N): This will cache N values and replay them to new subscribers.
3. A.withLatestFrom(B): Use this operator to get the most recent value from observable B when observable A emits. Will give you both values in an array [a, b].
4. A.combineLatest(B): Use this operator to get the most recent values from A and B every time either A or B emits. Will give you both values in an array.
5. shareReplay(): Makes an Observable multicast through a ReplaySubject, but allows you to retry the observable on error. (Basically it gives you that promise-y caching behavior).
6. publishReplay(), publishBehavior(initialValue), multicast(subject: BehaviorSubject | ReplaySubject), etc: Other operators that leverage BehaviorSubject and ReplaySubject. Different flavors of the same thing, they basically multicast the source observable by funneling all notifications through a subject. You need to call connect() to subscribe to the source with the subject.

I'm afraid Roman Luštrik's answer is wrong. It works on this input by chance. Consider for example its output on a very similar input (with an additional line similar to the original line 3 with "c" in the I2 column):

rum <- read.table(textConnection("P1  P2  P3  T1  T2  T3  I1  I2
2   3   5   52  43  61  6   b
6   4   3   72  NA  59  1   a
1   5   6   55  48  60  6   f
2   4   4   65  64  58  2   b
1   5   6   55  48  60  6   c"), header = TRUE)

rum$I2 <- as.character(rum$I2)
rum[order(rum$I1, rev(rum$I2), decreasing = TRUE), ]

  P1 P2 P3 T1 T2 T3 I1 I2
3  1  5  6 55 48 60  6  f
1  2  3  5 52 43 61  6  b
5  1  5  6 55 48 60  6  c
4  2  4  4 65 64 58  2  b
2  6  4  3 72 NA 59  1  a

This is not the desired result: the first three values of I2 are f b c instead of b c f, which would be expected since the secondary sort is I2 in ascending order.

To get the reverse order of I2, you want the large values to be small and vice versa. For numeric values multiplying by -1 will do it, but for characters its a bit more tricky. A general solution for characters/strings would be to go through factors, reverse the levels (to make large values small and small values large) and change the factor back to characters:

rum <- read.table(textConnection("P1  P2  P3  T1  T2  T3  I1  I2
2   3   5   52  43  61  6   b
6   4   3   72  NA  59  1   a
1   5   6   55  48  60  6   f
2   4   4   65  64  58  2   b
1   5   6   55  48  60  6   c"), header = TRUE)

f=factor(rum$I2)
levels(f) = rev(levels(f))
rum[order(rum$I1, as.character(f), decreasing = TRUE), ]

  P1 P2 P3 T1 T2 T3 I1 I2
1  2  3  5 52 43 61  6  b
5  1  5  6 55 48 60  6  c
3  1  5  6 55 48 60  6  f
4  2  4  4 65 64 58  2  b
2  6  4  3 72 NA 59  1  a

Saving to Hive is just a matter of using write() method of your SQLContext:

df.write.saveAsTable(tableName)

See https://spark.apache.org/docs/2.1.0/api/java/org/apache/spark/sql/DataFrameWriter.html#saveAsTable(java.lang.String)

From Spark 2.2: use DataSet instead DataFrame.

The simplest solution would be open terminal

$ java -version

it shows the following

java version "1.6.0_65"

2. Stefan's solution also works for me. Here's the exact input:

$ cd /System/Library/Frameworks/JavaVM.framework/Versions

$ ls -l

Below is the last line of output:

lrwxr-xr-x   1 root  wheel   59 Feb 12 14:57 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents

1.6.0.jdk would be the answer

Here is a simple solution which handles tabs and/or whitespaces in the filename. If you have to deal with other strange characters in the filename like newlines, pick another answer.

The test directory

ls -F test
Baltimore/  Cherry Hill/  Edison/  New York City/  Philadelphia/  cities.txt

The code to go into the directories

find test -type d | while read f ; do
  echo "$f"
done

The filename must be quoted ("$f") if used as argument. Without quotes, the spaces act as argument separator and multiple arguments are given to the invoked command.

And the output:

test/Baltimore
test/Cherry Hill
test/Edison
test/New York City
test/Philadelphia

create table Table1
(
  id varchar(2),
  name varchar(2),
  PRIMARY KEY (id)
)


Create table Table1_Addr
(
  addid varchar(2),
  Address varchar(2),
  PRIMARY KEY (addid)
)

Create table Table1_sal
(
  salid varchar(2),`enter code here`
  addid varchar(2),
  id varchar(2),
  PRIMARY KEY (salid),
  index(addid),
  index(id),
  FOREIGN KEY (addid) REFERENCES Table1_Addr(addid),
  FOREIGN KEY (id) REFERENCES Table1(id)
)

Another thing that messed things up for me was using localhost instead of 127.0.0.1 or vice versa. Apparently, JavaScript can't handle requests from one to the other.

Just a quick addition, because I tackled the same issue today:

With Go 1.13 it is possible to use the new isZero() method:

if reflect.ValueOf(session).IsZero() {
     // do stuff...
}

I didn't test this regarding performance, but I guess that this should be faster, than comparing via reflect.DeepEqual().

The simplest way is to edit .git/config

Here is an example file

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
        ignorecase = true
[remote "origin"]
        url = [email protected]:repo-name
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "test1"]
        remote = origin
        merge = refs/heads/test1
[branch "master"]
        remote = origin
        merge = refs/heads/master

Delete the line merge = refs/heads/test1 in the test1 branch section

The best methods are already given but why not look at a couple of other methods for fun? Warning: these are more expensive methods but do serve in other circumstances.

The expensive regex method and the css attribute selector with starts with ^ operator

Option Explicit

Public Sub test()

    Debug.Print StartWithSubString("ab", "abc,d")

End Sub

Regex:

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft VBScript Regular Expressions
    Dim re As VBScript_RegExp_55.RegExp
    Set re = New VBScript_RegExp_55.RegExp

    re.Pattern = "^" & substring

    StartWithSubString = re.test(testString)

End Function

Css attribute selector with starts with operator

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft HTML Object Library
    Dim html As MSHTML.HTMLDocument
    Set html = New MSHTML.HTMLDocument

    html.body.innerHTML = "<div test=""" & testString & """></div>"

    StartWithSubString = html.querySelectorAll("[test^=" & substring & "]").Length > 0

End Function

Sticky positioning is a hybrid of relative and fixed positioning. The element is treated as relative positioned until it crosses a specified threshold, at which point it is treated as fixed positioned.
...
You must specify a threshold with at least one of top, right, bottom, or left for sticky positioning to behave as expected. Otherwise, it will be indistinguishable from relative positioning. [source: MDN]

So in your example, you have to define the position where it should stick in the end by using the top property.

hooks can be executed when some condition is encountered. e.g. some variable changes or some action is called or some event happens. hooks can enter in the process and change things or react upon changes.

If you don't want to mess with ready libraries you can just make a class like this.

public class JsonConverter {

//Your class here, or you can define it in the constructor
Class requestclass = PositionKeeperRequestTest.class;

//Filename
String jsonFileName;

//constructor
public myJson(String jsonFileName){
    this.jsonFileName = jsonFileName;
}


//Returns a json object from an input stream
private JSONObject getJsonObject(){

    //Create input stream
    InputStream inputStreamObject = getRequestclass().getResourceAsStream(jsonFileName);

   try {
       BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStreamObject, "UTF-8"));
       StringBuilder responseStrBuilder = new StringBuilder();

       String inputStr;
       while ((inputStr = streamReader.readLine()) != null)
           responseStrBuilder.append(inputStr);

       JSONObject jsonObject = new JSONObject(responseStrBuilder.toString());

       //returns the json object
       return jsonObject;

   } catch (IOException e) {
       e.printStackTrace();
   } catch (JSONException e) {
       e.printStackTrace();
   }

    //if something went wrong, return null
    return null;
}

private Class getRequestclass(){
    return requestclass;
}
}

Then, you can use it like this:

JSONObject jObject = new JsonConverter(FILE_NAME).getJsonObject();

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>

from PIL import Image

background = Image.open("test1.png")
foreground = Image.open("test2.png")

background.paste(foreground, (0, 0), foreground)
background.show()

First parameter to .paste() is the image to paste. Second are coordinates, and the secret sauce is the third parameter. It indicates a mask that will be used to paste the image. If you pass a image with transparency, then the alpha channel is used as mask.

Check the docs.

You need to name the file in both directory paths.

When using LINQ extension methods (e.g. Select, Where), the lambda function might be converted to SQL that might not behave identically to your C# code. For instance, C#'s short-circuit evaluated && and || are converted to SQL's eager AND and OR. This can cause problems when you're checking for null in your lambda.

Example:

MyEnum? type = null;
Entities.Table.Where(a => type == null || 
    a.type == (int)type).ToArray();  // Exception: Nullable object must have a value

How can I use the binary operator alongside the date filter?

<span class="gallery-date">{{gallery.date | date:'mediumDate' || "Date Empty"}}</span>

you also try:

<span class="gallery-date">{{ gallery.date == 'NULL' ? 'mediumDate' : "gallery.date"}}</span>

I want to add one more thing to the @netbrain's answer relevant in case you use server-side processing (see serverSide option).

Query throttling performed by default by datatables (see searchDelay option) does not apply to the .search() API call. You can get it back by using $.fn.dataTable.util.throttle() in the following way:

var table = $('#myTable').DataTable();
var search = $.fn.dataTable.util.throttle(
    function(val) {
        table.search(val).draw();
    },
    400  // Search delay in ms
);

$('#mySearchBox').keyup(function() {
    search(this.value);
});

I assigned the javascript in my Controller:

model.linkCode = "window.open('https://www.yahoo.com', '_blank')";

And in my view:

@section Scripts{
    <script @Html.CspScriptNonce()>

    $(function () {

        @if (!String.IsNullOrEmpty(Model.linkCode))
        {
            WriteLiteral(Model.linkCode);
        }
    });

That opened a new tab with the link, and went to it.

Interestingly, run locally it engaged a popup blocker, but seemed to work fine on the servers.

Since it's a NodeList, not an Array, you shouldn't really be using brackets or casting to Array. The property way to get the first node is:

document.getElementsByName(id).item(0)

You can just cast that:

var script = <HTMLScriptElement> document.getElementsByName(id).item(0)

Or, extend NodeList:

interface HTMLScriptElementNodeList extends NodeList
{
    item(index: number): HTMLScriptElement;
}
var scripts = <HTMLScriptElementNodeList> document.getElementsByName('script'),
    script = scripts.item(0);

This solution mostly relies on TimestampType implementation with adding additional behaviour through anonymous class of type JdbcTimestampTypeDescriptor.

You need call in.close(), in a finally block to ensure it occurs.

From the Eclipse documentation, here is why it flags this particular problem (emphasis mine):

Classes implementing the interface java.io.Closeable (since JDK 1.5) and java.lang.AutoCloseable (since JDK 1.7) are considered to represent external resources, which should be closed using method close(), when they are no longer needed.

The Eclipse Java compiler is able to analyze whether code using such types adheres to this policy.

...

The compiler will flag [violations] with "Resource leak: 'stream' is never closed".

Full explanation here.

Here is a basic email validator I just created based on Simon Johnson's idea. It just needs the extra functionality of DNS lookup being added if it is required.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.UI.WebControls;
using System.Text.RegularExpressions;
using System.Web.UI;

namespace CompanyName.Library.Web.Controls
{
    [ToolboxData("<{0}:EmailValidator runat=server></{0}:EmailValidator>")]
    public class EmailValidator : BaseValidator
    {

        protected override bool EvaluateIsValid()
        {
            string val = this.GetControlValidationValue(this.ControlToValidate);
            string pattern = @"^[a-z][a-z|0-9|]*([_][a-z|0-9]+)*([.][a-z|0-9]+([_][a-z|0-9]+)*)?@[a-z][a-z|0-9|]*\.([a-z][a-z|0-9]*(\.[a-z][a-z|0-9]*)?)$";
            Match match = Regex.Match(val.Trim(), pattern, RegexOptions.IgnoreCase);

            if (match.Success)
                return true;
            else
                return false;
        }

    }
}

Update: Please don't use the original Regex. Seek out a newer more complete sample.

I would use this syntax

Delete a 
from TableA a
Inner Join TableB b
on  a.BId = b.BId
WHERE [filter condition]

ack works with similar arguments as grep, and accepts -C. But it's usually better for searching through code.

Series.reset_index with name argument

Often the use case comes up where a Series needs to be promoted to a DataFrame. But if the Series has no name, then reset_index will result in something like,

s = pd.Series([1, 2, 3], index=['a', 'b', 'c']).rename_axis('A')
s

A
a    1
b    2
c    3
dtype: int64

s.reset_index()

   A  0
0  a  1
1  b  2
2  c  3

Where you see the column name is "0". We can fix this be specifying a name parameter.

s.reset_index(name='B')

   A  B
0  a  1
1  b  2
2  c  3

s.reset_index(name='list')

   A  list
0  a     1
1  b     2
2  c     3

Series.to_frame

If you want to create a DataFrame without promoting the index to a column, use Series.to_frame, as suggested in this answer. This also supports a name parameter.

s.to_frame(name='B')

   B
A   
a  1
b  2
c  3

pd.DataFrame Constructor

You can also do the same thing as Series.to_frame by specifying a columns param:

pd.DataFrame(s, columns=['B'])

   B
A   
a  1
b  2
c  3

For the record to go back and forth in basic python3:

a = 10
bin(a)
# '0b1010'

int(bin(a), 2)
# 10
eval(bin(a))
# 10

Just to add to Alex Poole's answer, here is how you do the date and time:

    TO_DATE('31/DEC/2017 12:59:59', 'dd/mm/yyyy hh24:mi:ss')

If you are using jaxrs or any other, then there will be a class called mediatype.User interceptor before sending the request and compare it against this.

The tag is not closed:

$form.append("<input type=button value=button");

Should be:

$form.append('<input type="button" value="button">');

The complete first argument of exec is being interpreted as the executable. Use

p = rt.exec(new String[] {"winrar.exe", "x", "h:\\myjar.jar", "*.*", "h:\\new" }
            null, 
            dir);

I usually use numpy sum over the logical condition column:

>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame({'Age' : [20,24,18,5,78]})
>>> np.sum(df['Age'] > 20)
2

This seems to me slightly shorter than the solution presented above

What does sourcing the bash script for?

1. If you intend to switch between multiple virtualenvs or enter one virtualenv quickly, have you tried virtualenvwrapper? It provides a lot of utils like workon venv, mkvirtualenv venv and so on.

2. If you just run a python script in certain virtualenv, use /path/to/venv/bin/python script.py to run it.

The import wizard does offer that option. You can either use the option to write your own query for the data to import, or you can use the copy data option and use the "Edit Mappings" button to ignore columns you do not want to import.

Is there any specific reason you would want your buttons in an item template.You can alternatively do it the following way , there by giving you the full power of the grid row editing event.You are also given a bonus of wiring easily the cancel and delete functionality.

Mark up

<asp:TemplateField HeaderText="Edit">
            <ItemTemplate>
   <asp:ImageButton ID="EditImageButton" runat="server" CommandName="Edit"
    ImageUrl="~/images/Edit.png" Style="height: 16px" ToolTip="Edit" 
    CausesValidation="False"  />

      </ItemTemplate>

         <EditItemTemplate>

                    <asp:LinkButton ID="btnUpdate" runat="server" CommandName="Update" 
                        Text="Update"  Visible="true" ImageUrl="~/images/saveHS.png" 
                        />
                   <asp:LinkButton ID="btnCancel" runat="server" CommandName="Cancel"   
                        ImageUrl="~/images/Edit_UndoHS.png"  />

                 <asp:LinkButton ID="btnDelete" runat="server" CommandName="Delete"   
                        ImageUrl="~/images/delete.png"  />

             </EditItemTemplate>


        <ControlStyle BackColor="Transparent" BorderStyle="None" />
               <FooterStyle HorizontalAlign="Center" />
           <ItemStyle HorizontalAlign="Center" />
       </asp:TemplateField>

Code behind

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{

    GridView1.EditIndex = e.NewEditIndex;
    GridView1.DataBind();

TextBox txtledName =   (TextBox) GridView1.Rows[e.NewEditIndex].FindControl("txtAccountName");

 //then do something with the retrieved textbox's text.

}

As explained here by Filip - http://www.filipekberg.se/2011/10/02/adding-properties-and-methods-to-an-expandoobject-dynamicly/

You can add a method too at runtime.

x.Add("Shout", new Action(() => { Console.WriteLine("Hellooo!!!"); }));
x.Shout();

You should open text files using rU so newlines are properly transformed, see http://docs.python.org/library/functions.html#open. This way there's no need to check for \r\n.

Tuple classes allow developers to be 'quick and lazy' by not defining a specific class for a specific use.

The property names are Item1, Item2, Item3 ..., which may not be meaningful in some cases or without documentation.

Tuple classes have strongly typed generic parameters. Still users of the Tuple classes may infer from the type of generic parameters.

If you just want to tack something on by hand, then the sed answer will work for you. If instead the text is in file(s) (say file1.txt and file2.txt):

Using Perl:

perl -e 'open(OUT, ">>", "outfile.txt"); print OUT while (<>);' file*.txt

N.B. while the >> may look like an indication of redirection, it is just the file open mode, in this case "append".

This is how I calculated the real dimensions for the first letter (you can change the method header to suit your needs, i.e. instead of char[] use String):

private void calculateTextSize(char[] text, PointF outSize) {
    // use measureText to calculate width
    float width = mPaint.measureText(text, 0, 1);

    // use height from getTextBounds()
    Rect textBounds = new Rect();
    mPaint.getTextBounds(text, 0, 1, textBounds);
    float height = textBounds.height();
    outSize.x = width;
    outSize.y = height;
}

Note that I'm using TextPaint instead of the original Paint class.

For the question:

How to save Console.Writeline Outputs to text file?

I would use Console.SetOut as others have mentioned.

However, it looks more like you are keeping track of your program flow. I would consider using Debug or Trace for keeping track of the program state.

It works similar the console except you have more control over your input such as WriteLineIf.

Debug will only operate when in debug mode where as Trace will operate in both debug or release mode.

They both allow for listeners such as output files or the console.

TextWriterTraceListener tr1 = new TextWriterTraceListener(System.Console.Out);
Debug.Listeners.Add(tr1);

TextWriterTraceListener tr2 = new TextWriterTraceListener(System.IO.File.CreateText("Output.txt"));
Debug.Listeners.Add(tr2);

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

To get Solution working you need to include the file csi.min.js, which you can locate here.

As per the example shown on GitHub, to use this library you must include the file csi.js in your page header, then you need to add the data-include attribute with its value set to the file you want to include, on the container element.

Hide Copy Code

<html>
  <head>
    <script src="csi.js"></script>
  </head>
  <body>
    <div data-include="Test.html"></div>
  </body>
</html>

... hope it helps.

In newer versions change was made to the flags: from the documentation:

--extended-insert, -e

Write INSERT statements using multiple-row syntax that includes several VALUES lists. This results in a smaller dump file and speeds up inserts when the file is reloaded.

--opt

This option, enabled by default, is shorthand for the combination of --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset. It gives a fast dump operation and produces a dump file that can be reloaded into a MySQL server quickly.

Because the --opt option is enabled by default, you only specify its converse, the --skip-opt to turn off several default settings. See the discussion of mysqldump option groups for information about selectively enabling or disabling a subset of the options affected by --opt.

--skip-extended-insert

Turn off extended-insert

Take a look at the $_GET and $_REQUEST superglobals. Something like the following would work for your example:

$start = $_GET['start'];
$limit = $_GET['limit'];

EDIT

According to this post in the laravel forums, you need to use Input::get(), e.g.,

$start = Input::get('start');
$limit = Input::get('limit');

See also: http://laravel.com/docs/input#input

Did you try adding the self prefix to the fileName and replacing the method above the Button ? With the self, it becomes visible between methods.

...

def load_file(self):
    self.fileName = filedialog.askopenfilename(filetypes = (("Template files", "*.tplate")
                                                     ,("HTML files", "*.html;*.htm")
                                                     ,("All files", "*.*") ))
...

There is, indeed, prevision for such feature, look http://www.w3.org/TR/css3-values/#attr-notation

This fiddle should work like what you need, but will not for now.

Unfortunately, it's still a draft, and isn't fully implemented on major browsers.

It does work for content on pseudo-elements, though.

it's easier to check first if the channel has elements, that would ensure the channel is alive.

func isChanClosed(ch chan interface{}) bool {
    if len(ch) == 0 {
        select {
        case _, ok := <-ch:
            return !ok
        }
    }
    return false 
}

Remove "SSLv2ClientHello" from the enabled protocols on the client SSLSocket or HttpsURLConnection.

I had this same problem in a large Excel 2000 spreadsheet with hundreds of lines of code. My solution was to make the Worksheet active at the beginning of the Class. I.E. ThisWorkbook.Worksheets("WorkSheetName").Activate This was finally discovered when I noticed that if "WorkSheetName" was active when starting the operation (the code) the error didn't occur. Drove me crazy for quite awhile.

As a rephrasing of Andrey's answer:

The Boost TypeIndex library can be used to print names of types.

Inside a template, this might read as follows

#include <boost/type_index.hpp>
#include <iostream>

template<typename T>
void printNameOfType() {
    std::cout << "Type of T: " 
              << boost::typeindex::type_id<T>().pretty_name() 
              << std::endl;
}

You can also use the .btn-block class on the button, so that it expands to the parent's width.

If the parent is a fixed width element the button will expand to take all width. You can apply existing markup to the container to ensure fixed/fluid buttons take up only the required space.

<div class="span2">
<p><button class="btn btn-primary btn-block">Save</button></p>
<p><button class="btn btn-success btn-block">Download</button></p>
</div>

I thought it could be worthwhile to have a micro-benchmark comparing the run-times of the different approaches mentioned here.

Disclaimer: I'm using simple_benchmark (a library written by me) for the benchmarks and also include iteration_utilities.count_items (a function in a third-party-library written by me).

To provide a more differentiated result I've done two benchmarks, one only including the approaches that don't build an intermediate container just to throw it away and one including these:

from simple_benchmark import BenchmarkBuilder
import more_itertools as mi
import iteration_utilities as iu

b1 = BenchmarkBuilder()
b2 = BenchmarkBuilder()

@b1.add_function()
@b2.add_function()
def summation(it):
    return sum(1 for _ in it)

@b1.add_function()
def len_list(it):
    return len(list(it))

@b1.add_function()
def len_listcomp(it):
    return len([_ for _ in it])

@b1.add_function()
@b2.add_function()
def more_itertools_ilen(it):
    return mi.ilen(it)

@b1.add_function()
@b2.add_function()
def iteration_utilities_count_items(it):
    return iu.count_items(it)

@b1.add_arguments('length')
@b2.add_arguments('length')
def argument_provider():
    for exp in range(2, 18):
        size = 2**exp
        yield size, [0]*size

r1 = b1.run()
r2 = b2.run()

import matplotlib.pyplot as plt

f, (ax1, ax2) = plt.subplots(2, 1, sharex=True, figsize=[15, 18])
r1.plot(ax=ax2)
r2.plot(ax=ax1)
plt.savefig('result.png')

The results were:

It uses log-log-axis so that all ranges (small values, large values) can be inspected. Since the plots are intended for qualitative comparison the actual values aren't too interesting. In general the y-axis (vertical) represents the time and the x-axis (horizontal) represents the number of elements in the input "iterable". Lower on the vertical axis means faster.

The upper plot shows the approaches where no intermediate list was used. Which shows that the iteration_utilities approach was fastest, followed by more_itertools and the slowest was using sum(1 for _ in iterator).

The lower plot also included the approaches that used len() on an intermediate list, once with list and once with a list comprehension. The approach with len(list) was fastest here, but the difference to the iteration_utilities approach is almost negligible. The approach using the comprehension was significantly slower than using list directly.

Summary

Any approach mentioned here did show a dependency on the length of the input and iterated over ever element in the iterable. There is no way to get the length without the iteration (even if the iteration is hidden).

If you don't want third-party extensions then using len(list(iterable)) is definitely the fastest approach of the tested approaches, it however generates an intermediate list which could use significant more memory.

If you don't mind additional packages then iteration_utilities.count_items would be almost as fast as the len(list(...)) function but doesn't require additional memory.

However it's important to note that the micro-benchmark used a list as input. The result of the benchmark could be different depending on the iterable you want to get the length of. I also tested with range and a simple genertor-expression and the trends were very similar, however I cannot exclude that the timing won't change depending on the type of input.

Using d-flex class works well but some other attributes don't work anymore like vertical-align: middle property.

The best way I found to size columns very easily is to use the width attribute with percentage only in thead cells.

<table class="table">
    <thead>
        <tr>
            <th width="25%">25%</th>
            <th width="25%">25%</th>
            <th width="50%">50%</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>25%</td>
            <td>25%</td>
            <td>50%</td>
        </tr>
    </tbody>
</table>

I had the error after trying to select a subset of rows:

df = df.reindex(index=my_index)

Turns out that my_index contained values that were not contained in df.index, so the reindex function inserted some new rows and filled them with nan.

you can try

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));

Document doc = db.parse(is);

refer this http://www.java2s.com/Code/Java/XML/ParseanXMLstringUsingDOMandaStringReader.htm

I solved mine using the whole url of the PDF file (Instead of just putting the file name or location to href): a href="domain . com/pdf/filename.pdf"

For the times when some fields have a ";" and some do not you can also add a semi-colon to the field and use the same method described.

SET MyText = LEFT(MyText+';', CHARINDEX(';',MyText+';')-1)

Here is the bash script I used to detect three different OS type (GNU/Linux, Mac OS X, Windows NT)

Pay attention

• In your bash script, use #!/usr/bin/env bash instead of #!/bin/sh to prevent the problem caused by /bin/sh linked to different default shell in different platforms, or there will be error like unexpected operator, that's what happened on my computer (Ubuntu 64 bits 12.04).
• Mac OS X 10.6.8 (Snow Leopard) do not have expr program unless you install it, so I just use uname.

Design

1. Use uname to get the system information (-s parameter).
2. Use expr and substr to deal with the string.
3. Use if elif fi to do the matching job.
4. You can add more system support if you want, just follow the uname -s specification.

Implementation

#!/usr/bin/env bash

if [ "$(uname)" == "Darwin" ]; then
    # Do something under Mac OS X platform        
elif [ "$(expr substr $(uname -s) 1 5)" == "Linux" ]; then
    # Do something under GNU/Linux platform
elif [ "$(expr substr $(uname -s) 1 10)" == "MINGW32_NT" ]; then
    # Do something under 32 bits Windows NT platform
elif [ "$(expr substr $(uname -s) 1 10)" == "MINGW64_NT" ]; then
    # Do something under 64 bits Windows NT platform
fi

Testing

• Linux (Ubuntu 12.04 LTS, Kernel 3.2.0) tested OK.
• OS X (10.6.8 Snow Leopard) tested OK.
• Windows (Windows 7 64 bit) tested OK.

What I learned

1. Check for both opening and closing quotes.
2. Check for missing parentheses and braces {}

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

After testing it with RSpec like this:

describe Hash do
  describe :map_values do
    it 'should map the values' do
      expect({:a => 2, :b => 3}.map_values { |x| x ** 2 }).to eq({:a => 4, :b => 9})
    end
  end
end

You could implement Hash#map_values as follows:

class Hash
  def map_values
    Hash[map { |k, v| [k, yield(v)] }]
  end
end

The function then can be used like this:

{:a=>'a' , :b=>'b'}.map_values { |v| "%#{v}%" }
# {:a=>"%a%", :b=>"%b%"}

There are some really nice answers here, but apparently the simplest is not taken too much in consideration (only from infinito).

root_logger = logging.getLogger()
root_logger.disabled = True

This disables the root logger, and thus all the other loggers. I haven't really tested but it should be also the fastest.

From the logging code in python 2.7 I see this

def handle(self, record):
    """
    Call the handlers for the specified record.

    This method is used for unpickled records received from a socket, as
    well as those created locally. Logger-level filtering is applied.
    """
    if (not self.disabled) and self.filter(record):
        self.callHandlers(record)

Which means that when it's disabled no handler is called, and it should be more efficient that filtering to a very high value or setting a no-op handler for example.

In my opinion, we should not RUN npm install in the Dockerfile. Instead, we can start a container using bash to install the dependencies before runing the formal node service

docker run -it -v ./app:/usr/src/app  your_node_image_name  /bin/bash
root@247543a930d6:/usr/src/app# npm install

turn on display errors in your ini

Java binaries may be under "Program Files" or "Program Files (x86)": those white spaces will likely affect the behaviour.

In order to set up env variables correctly, I suggest gathering some info before starting:

• Open DOS shell (type cmd into 'RUN' box) go to C:\
• type "dir /x" and take note of DOS names (with ~) for "Program Files *" folders

Cygwin configuration:

go under C:\cygwin\home\, then open .bash_profile and add the following two lines (conveniently customized in order to match you actual JDK path)

export JAVA_HOME="/cygdrive/c/PROGRA~1/Java/jdk1.8.0_65"
export PATH="$JAVA_HOME/bin:$PATH"

Now from Cygwin launch

javac -version

to check if the configuration is successful.

I have created this jquery that solved my problem.

public void ChangeClassIntoSelected(String name,String div) {
        JavascriptExecutor js = (JavascriptExecutor) driver;
        js.executeScript("Array.from($(\"div." + div +" ul[name=" + name + "]\")[0].children).forEach((element, index) => {\n" +
                "   $(element).addClass('ui-selected');\n" +
                "});");
    }

With this script you are able to change the actual class name into some other thing.

Template File

<h1>{title}</h1>
<div>{username}</div>

PHP

if (($text = file_get_contents("file.html")) === false) {
    $text = "";
}

$text = str_replace("{title}", "Title Here", $text);
$text = str_replace("{username}", "Username Here", $text);

then you can echo $text as string

Following issue 8959, a good start would be:

docker ps -a -q --filter="name=<containerName>"

Since name refers to the container and not the image name, you would need to use the more recent Docker 1.9 filter ancestor, mentioned in koekiebox's answer.

docker ps -a -q  --filter ancestor=<image-name>

As commented below by kiril, to remove those containers:

stop returns the containers as well.

So chaining stop and rm will do the job:

docker rm $(docker stop $(docker ps -a -q --filter ancestor=<image-name> --format="{{.ID}}"))

Since the sender of the event handler is the button itself, I'd use the button's tag property to store the index, initialized in cellForRowAtIndexPath.

But with a little more work I'd do in a completely different way. If you are using a custom cell, this is how I would approach the problem:

• add an 'indexPath` property to the custom table cell
• initialize it in cellForRowAtIndexPath
• move the tap handler from the view controller to the cell implementation
• use the delegation pattern to notify the view controller about the tap event, passing the index path

 StringUtils.leftPad(yourString, 8, '0');

This is from commons-lang. See javadoc

The Ubuntu package docker actually refers to a GUI application, not the beloved DevOps tool we've come out to look for.

The instructions for docker can be followed per instructions on the docker page here: https://docs.docker.com/engine/install/ubuntu/

=== UPDATED (thanks @Scott Stensland) ===

You now run the following install script to get docker:

`sudo curl -sSL https://get.docker.com/ | sh`

• Note: review the script on the website and make sure you have the right link before continuing since you are running this as sudo.

This will run a script that installs docker. Note the last part of the script:

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  `sudo usermod -aG docker stens`

Remember that you will have to log out and back in for this to take effect!

To update Docker run:

`sudo apt-get update && sudo apt-get upgrade`

For more details on what's going on, See the docker install documentation or @Scott Stensland's answer below

.

=== UPDATE: For those uncomfortable w/ sudo | sh ===

Some in the comments have mentioned that it a risk to run an arbitrary script as sudo. The above option is a convenience script from docker to make the task simple. However, for those that are security-focused but don't want to read the script you can do the following:

1. Add Dependencies

sudo apt-get update; \
sudo apt-get install \
 apt-transport-https \
 ca-certificates \
 curl \
 gnupg-agent \
 software-properties-common

2. Add docker gpg key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

(Security check, verify key fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88

$ sudo apt-key fingerprint 0EBFCD88

pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <[email protected]>
sub   rsa4096 2017-02-22 [S]

)

3. Setup Repository

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

4. Install Docker

sudo apt-get update; \
sudo apt-get install docker-ce docker-ce-cli containerd.io

If you want to verify that it worked run: sudo docker run hello-world

The following explains why it is named like this: Why install docker on ubuntu should be `sudo apt-get install docker.io`?

I had the same problem. In my case it arises, because the lookup-table "country" has an existing record with countryId==0 and a primitive primary key and I try to save a User with a countryID==0. Change the primary key of country to Integer. Now Hibernate can identify new records.

For the recommendation of using wrapper classes as primary key see this stackoverflow question

I believe that as of PHP 5.3, you can use const outside of classes, as shown here in the second example:

http://www.php.net/manual/en/language.constants.syntax.php

<?php
// Works as of PHP 5.3.0
const CONSTANT = 'Hello World';

echo CONSTANT;
?>

A more simple English explanation: jQuery is something that makes AJAX and other JavaScript tasks much easier.

For IIS 8 There is a extra step to do other than changing the customErrors=Off to show the error content.

<system.web>
   <customErrors mode="Off" />
</system.web>
<system.webServer>
   <httpErrors existingResponse="PassThrough" errorMode="Detailed"/>
</system.webServer>

Raul answered the question in this link Turn off IIS8 custom errors by Raul

You need to move it to another file (rather than a folder), this can also be used to rename.

Move:

File.Move(@"c:\test\SomeFile.txt", @"c:\test\Test\SomeFile.txt");

Rename:

File.Move(@"c:\test\SomeFile.txt", @"c:\test\SomeFile2.txt");

The reason it says "File already exists" in your example, is because C:\test\Test tries to create a file Test without an extension, but cannot do so as a folder already exists with the same name.

The best thing to do is.

1. fork twitter-bootstrap from github and clone locally.

they are changing really quickly the library/framework (they diverge internally. Some prefer library, i'd say that it's a framework, because change your layout from the time you load it on your page). Well... forking/cloning will let you fetch the new upcoming versions easily.

2. Do not modify the bootstrap.css file

It's gonna complicate your life when you need to upgrade bootstrap (and you will need to do it).

3. Create your own css file and overwrite whenever you want original bootstrap stuff

if they set a topbar with, let's say, color: black; but you wan it white, create a new very specific selector for this topbar and use this rule on the specific topbar. For a table for example, it would be <table class="zebra-striped mycustomclass">. If you declare your css file after bootstrap.css, this will overwrite whatever you want to.

TL;DR: np.random.shuffle(ndarray) can do the job.
So, in your case

np.random.shuffle(DataFrame.values)

DataFrame, under the hood, uses NumPy ndarray as data holder. (You can check from DataFrame source code)

So if you use np.random.shuffle(), it would shuffles the array along the first axis of a multi-dimensional array. But index of the DataFrame remains unshuffled.

Though, there are some points to consider.

• function returns none. In case you want to keep a copy of the original object, you have to do so before you pass to the function.
• sklearn.utils.shuffle(), as user tj89 suggested, can designate random_state along with another option to control output. You may want that for dev purpose.
• sklearn.utils.shuffle() is faster. But WILL SHUFFLE the axis info(index, column) of the DataFrame along with the ndarray it contains.

Benchmark result

between sklearn.utils.shuffle() and np.random.shuffle().

ndarray

nd = sklearn.utils.shuffle(nd)

0.10793248389381915 sec. 8x faster

np.random.shuffle(nd)

0.8897626010002568 sec

DataFrame

df = sklearn.utils.shuffle(df)

0.3183923360193148 sec. 3x faster

np.random.shuffle(df.values)

0.9357550159329548 sec

Conclusion: If it is okay to axis info(index, column) to be shuffled along with ndarray, use sklearn.utils.shuffle(). Otherwise, use np.random.shuffle()

used code

import timeit
setup = '''
import numpy as np
import pandas as pd
import sklearn

export PYTHONIOENCODING=utf-8

do the job, but can't set it on python itself ...

what we can do is verify if isn't setting and tell the user to set it before call script with :

if __name__ == '__main__':
    if (sys.stdout.encoding is None):
        print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout."
        exit(1)

Update to reply to the comment: the problem just exist when piping to stdout . I tested in Fedora 25 Python 2.7.13

python --version
Python 2.7.13

cat b.py

#!/usr/bin/env python
#-*- coding: utf-8 -*-
import sys

print sys.stdout.encoding

chmod -R 755 directory_name works, but how would you keep new files to 755 also? The file's permissions becomes the default permission.

Here's a couple of functions (based on Brian Bondy's example) that use WideCharToMultiByte and MultiByteToWideChar to convert between std::wstring and std::string using utf8 to not lose any data.

// Convert a wide Unicode string to an UTF8 string
std::string utf8_encode(const std::wstring &wstr)
{
    if( wstr.empty() ) return std::string();
    int size_needed = WideCharToMultiByte(CP_UTF8, 0, &wstr[0], (int)wstr.size(), NULL, 0, NULL, NULL);
    std::string strTo( size_needed, 0 );
    WideCharToMultiByte                  (CP_UTF8, 0, &wstr[0], (int)wstr.size(), &strTo[0], size_needed, NULL, NULL);
    return strTo;
}

// Convert an UTF8 string to a wide Unicode String
std::wstring utf8_decode(const std::string &str)
{
    if( str.empty() ) return std::wstring();
    int size_needed = MultiByteToWideChar(CP_UTF8, 0, &str[0], (int)str.size(), NULL, 0);
    std::wstring wstrTo( size_needed, 0 );
    MultiByteToWideChar                  (CP_UTF8, 0, &str[0], (int)str.size(), &wstrTo[0], size_needed);
    return wstrTo;
}

I have acheived this in JQuery by putting a zero width strut element above the float right, then sizing the strut (or pipe) according to parent height minus floated child's height.

Before js kicks in I am using the position absolute approach, which works but allows text flow behind. Therefore I switch to position static to enable the strut approach. (header is the parent element, cutout is the one i want bottom right, and pipe is my strut)

$("header .pipe").each(function(){
    $(this).next(".cutout").css("position","static");       
    $(this).height($(this).parent().height()-$(this).next(".cutout").height());                                                 
});

CSS

header{
    position: relative; 
}

header img.cutout{
    float:right;
    position:absolute;
    bottom:0;
    right:0;
    clear:right
}
header .pipe{
    width:0px; 
    float:right

}

The pipe must come 1st, then the cutout, then the text in the HTML order.

Maybe a little late, but I found an easier way to set the defaults! You have to right-click on the right of your tab and choose "size", then click on your window, and it should keep it as the default size.

Open services.msc directly from command prompt and disabled SQL Server reporting services

& SQL Server analysis services.

It's as simple as:

watch: {
  '$store.state.drawer': function() {
    console.log(this.$store.state.drawer)
  }
}

document.getElementsByClassName("classstringhere").length

The document.getElementsByClassName("classstringhere") method returns an array of all the elements with that class name, so .length gives you the amount of them.

Spring Boot already has support for profile based properties.

Simply add an application-[profile].properties file and specify the profiles to use using the spring.profiles.active property.

-Dspring.profiles.active=local

This will load the application.properties and the application-local.properties with the latter overriding properties from the first.

Running shell scripts that have contain sudo commands in them from jenkins might not run as expected. To fix this, follow along

Simple steps:

1. On ubuntu based systems, run " $ sudo visudo "

2. this will open /etc/sudoers file.

3. If your jenkins user is already in that file, then modify to look like this:

jenkins ALL=(ALL) NOPASSWD: ALL

4. save the file

5. Relaunch your jenkins job

6. you shouldnt see that error message again :)

if the 2 structures variable are initialied with calloc or they are set with 0 by memset so you can compare your 2 structures with memcmp and there is no worry about structure garbage and this will allow you to earn time

In IntelliJ Do as they say in eclipse "If you're facing this problem with Eclipse, I've been following many different solutions but the one that worked for me is this:

Select Add External JARs to import the mysql driver.

From the right panel, select Deployment Assembly.

Select Add..., then select Java Build Path Entries and click Next.

You should see the sql driver on the list. Select it and click first.

And that's it! Try to run it again! Cheers!"

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

Edit: The following could be used to fingerprint small files before and after transfer (use SHA if you feel it's necessary):

public static String md5String(File file) {
    try {
        InputStream fin = new FileInputStream(file);
        java.security.MessageDigest md5er = MessageDigest.getInstance("MD5");
        byte[] buffer = new byte[1024];
        int read;
        do {
            read = fin.read(buffer);
            if (read > 0) {
                md5er.update(buffer, 0, read);
            }
        } while (read != -1);
        fin.close();
        byte[] digest = md5er.digest();
        if (digest == null) {
            return null;
        }
        String strDigest = "0x";
        for (int i = 0; i < digest.length; i++) {
            strDigest += Integer.toString((digest[i] & 0xff)
                    + 0x100, 16).substring(1).toUpperCase();
        }
        return strDigest;
    } catch (Exception e) {
        return null;
    }
}

I am using gedit basic version that comes with Ubuntu 11.10. I had the same error. This is mainly caused when you mix spaces with tabs.

A good way to differentiate as to which lines have problem would be to go to: 1. edit 2. preferences 3. editor 4. check "automatic indentation" 5. increase the indentation to 12 or some big number

after doing the fifth step you will be able to see the lines of your code that are relly causing problem (these are the lines that have a mix of space and tab)

Make the entire code convention as just TAB or just SPACE (this has to be done manually line by line)

Hope this helps...

Can you set the password to the phpmyadmin here

$('#myformelement').append('<input type="hidden" name="myfieldname" value="myvalue" />');

I like @jesterjunk answer, however, a number is not always just digits. Consider those valid numbers: "123.5, 123,567.789, 12233234+E12"

So I just updated the regular expression:

var regex = /[\d|,|.|e|E|\+]+/g;

var string = "you can enter maximum 5,123.6 choices";
var matches = string.match(regex);  // creates array from matches

document.write(matches); //5,123.6
