Just another take, this is what native JavaScript functions Map and Reduce were built for (Map and Reduce are powerhouses in many languages).

var traveler = [{description: 'Senior', Amount: 50},
                {description: 'Senior', Amount: 50},
                {description: 'Adult', Amount: 75},
                {description: 'Child', Amount: 35},
                {description: 'Infant', Amount: 25}];

function amount(item){
  return item.Amount;
}

function sum(prev, next){
  return prev + next;
}

traveler.map(amount).reduce(sum);
// => 235;

// or use arrow functions
traveler.map(item => item.Amount).reduce((prev, next) => prev + next);

Note: by making separate smaller functions we get the ability to use them again.

// Example of reuse.
// Get only Amounts greater than 0;

// Also, while using Javascript, stick with camelCase.
// If you do decide to go against the standards, 
// then maintain your decision with all keys as in...

// { description: 'Senior', Amount: 50 }

// would be

// { Description: 'Senior', Amount: 50 };

var travelers = [{description: 'Senior', amount: 50},
                {description: 'Senior', amount: 50},
                {description: 'Adult', amount: 75},
                {description: 'Child', amount: 35},
                {description: 'Infant', amount: 0 }];

// Directly above Travelers array I changed "Amount" to "amount" to match standards.

function amount(item){
  return item.amount;
}

travelers.filter(amount);
// => [{description: 'Senior', amount: 50},
//     {description: 'Senior', amount: 50},
//     {description: 'Adult', amount: 75},
//     {description: 'Child', amount: 35}];
//     Does not include "Infant" as 0 is falsey.

You are right that greediness is an issue:

--A--Z--A--Z--
  ^^^^^^^^^^
     A.*Z

If you want to match both A--Z, you'd have to use A.*?Z (the ? makes the * "reluctant", or lazy).

There are sometimes better ways to do this, though, e.g.

A[^Z]*+Z

This uses negated character class and possessive quantifier, to reduce backtracking, and is likely to be more efficient.

In your case, the regex would be:

/(\[[^\]]++\])/

Unfortunately Javascript regex doesn't support possessive quantifier, so you'd just have to do with:

/(\[[^\]]+\])/

See also

• regular-expressions.info/Repetition
  • See: An Alternative to Laziness
    • Possessive quantifiers
  • Flavors comparison

Quick summary

*   Zero or more, greedy
*?  Zero or more, reluctant
*+  Zero or more, possessive

+   One or more, greedy
+?  One or more, reluctant
++  One or more, possessive

?   Zero or one, greedy
??  Zero or one, reluctant
?+  Zero or one, possessive

Note that the reluctant and possessive quantifiers are also applicable to the finite repetition {n,m} constructs.

Examples in Java:

System.out.println("aAoZbAoZc".replaceAll("A.*Z", "!"));  // prints "a!c"
System.out.println("aAoZbAoZc".replaceAll("A.*?Z", "!")); // prints "a!b!c"

System.out.println("xxxxxx".replaceAll("x{3,5}", "Y"));  // prints "Yx"
System.out.println("xxxxxx".replaceAll("x{3,5}?", "Y")); // prints "YY"

I would add for Debian you need at least one compiler in the system (according to Debian Stretch and Jessie 32-bit libraries ).

I installed apt-get install -y gcc-multilib in order to run 32-bit executable file in my docker container based on debian:jessie.

The solution documented by Apple in Technical Q&A QA1747 Debugging Deployed iOS Apps for Xcode 6 is:

1. Choose Window -> Devices from the Xcode menu.
2. Choose the device in the left column.
3. Click the up-triangle at the bottom left of the right hand panel to show the device console.

Also, consider to use a repository manager such as Nexus and configure all your repositories there.

I believe its in /tmp/. Check your phpinfo function though, it should say session.save_path in there somewhere.

Use this method to set custom cell height width.

Make sure to add this protocols

UICollectionViewDelegate

UICollectionViewDataSource

UICollectionViewDelegateFlowLayout

If you are using swift 5 or xcode 11 and later you need to set Estimate Size to none using storyboard in order to make it work properly. If you will not set that than below code will not work as expected.

Swift 4 or Later

extension YourViewController: UICollectionViewDelegate {
    //Write Delegate Code Here
}

extension YourViewController: UICollectionViewDataSource {
    //Write DataSource Code Here
}

extension YourViewController: UICollectionViewDelegateFlowLayout {
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        return CGSize(width: screenWidth, height: screenWidth)
    }
}

Objective-C

@interface YourViewController : UIViewController<UICollectionViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout>

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    return CGSizeMake(CGRectGetWidth(collectionView.frame), (CGRectGetHeight(collectionView.frame)));
}

Try the DrawEllipse method instead.

The answer about threading is good, but you need to be a bit more specific about what you want to do.

If you have two functions that both use a lot of CPU, threading (in CPython) will probably get you nowhere. Then you might want to have a look at the multiprocessing module or possibly you might want to use jython/IronPython.

If CPU-bound performance is the reason, you could even implement things in (non-threaded) C and get a much bigger speedup than doing two parallel things in python.

Without more information, it isn't easy to come up with a good answer.

Use range() instead, like the following :

for i in range(len(words)):
    ...

first select datagrid and then go to properties find Datagrid_AutoGeneratingColumn and the double click And then use this code

   Datagrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
            {
                if (e.PropertyName == "Your column name")
                    (e.Column as DataGridTextColumn).Binding.StringFormat = "dd/MMMMMMMMM/yyyy";
                if (e.PropertyName == "Your column name")
                    (e.Column as DataGridTextColumn).Binding.StringFormat = "dd/MMMMMMMMM/yyyy";
            }

I try it it works on WPF

You can create a way to define static constants on a class using an odd feature of ES6 classes. Since statics are inherited by their subclasses, you can do the following:

const withConsts = (map, BaseClass = Object) => {
  class ConstClass extends BaseClass { }
  Object.keys(map).forEach(key => {
    Object.defineProperty(ConstClass, key, {
      value: map[key],
      writable : false,
      enumerable : true,
      configurable : false
    });
  });
  return ConstClass;
};

class MyClass extends withConsts({ MY_CONST: 'this is defined' }) {
  foo() {
    console.log(MyClass.MY_CONST);
  }
}

I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:

Make sure ESLint is not run with the --no-inline-config flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):

/* eslint-env browser */

This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.

There are plenty of environments, and you can declare more than one at the same time, for example, in-line:

/* eslint-env browser, node */

If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.

From their docs:

An environment defines global variables that are predefined. The available environments are:

• browser - browser global variables.
• node - Node.js global variables and Node.js scoping.
• commonjs - CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).
• shared-node-browser - Globals common to both Node and Browser.

[...]

Besides environments, you can make it ignore anything you want. If it warns you about using console.log() but you don't want to be warned about it, just inline:

/* eslint-disable no-console */

You can see the list of all rules, including recommended rules to have for best coding practices.

I am adding an answer using raw CSS3 and SVG without requiring LESS or SASS.

Basically, if the question is to make a colour 10%,25%,50% ligher or darker for the sakes of a global hover effect you can create an SVG data call like this

:root{
--lighten-bg: url('data:image/svg+xml;utf8,<svg version="1.1" id="cssLighten" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="50px" height="50px" viewBox="0 0 50 50" enable-background="new 0 0 50 50" xml:space="preserve"><rect opacity="0.2" fill="white" width="50" height="50"/></svg>') !important;
--darken-bg: url('data:image/svg+xml;utf8,<svg version="1.1" id="cssDarken" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="50px" height="50px" viewBox="0 0 50 50" enable-background="new 0 0 50 50" xml:space="preserve"><rect opacity="0.2" fill="black" width="50" height="50"/></svg>') !important;

}

.myButton{
    color: white;
    background-color:blue;
}
.myButton:hover{
    background-image: var(--lighten-bg);
}

For some reason, unknown to me, the SVG won't allow me to enter a hex value in the "fill" attribute but "white" and "black" satisfy my need.

Food for thought: If you didn't mind using images, just use a 50% transparent PNG as the background image. If you wanted to be fancy, call a PHP script as the background image and pass it the HEX and OPACITY values and let it spit out the SVG code above.

By default - No.

There's the length property that is commonly used for the same result in the following way:

if ($(selector).length)

Here, 'selector' is to be replaced by the actual selector you are interested to find if it exists or not. If it does exist, the length property will output an integer more than 0 and hence the if statement will become true and hence execute the if block. If it doesn't, it will output the integer '0' and hence the if block won't get executed.

To compare two objects you can use:

angular.equals(obj1, obj2)

It does a deep comparison and does not depend on the order of the keys See AngularJS DOCS and a little Demo

var obj1 = {
  key1: "value1",
  key2: "value2",
  key3: {a: "aa", b: "bb"}
}

var obj2 = {
  key2: "value2",
  key1: "value1",
  key3: {a: "aa", b: "bb"}
}

angular.equals(obj1, obj2) //<--- would return true

For the syntax, it looks like this (leave out the column list to implicitly mean "all")

INSERT INTO this_table_archive
SELECT *
FROM this_table
WHERE entry_date < '2011-01-01 00:00:00'

For avoiding primary key errors if you already have data in the archive table

INSERT INTO this_table_archive
SELECT t.*
FROM this_table t
LEFT JOIN this_table_archive a on a.id=t.id
WHERE t.entry_date < '2011-01-01 00:00:00'
  AND a.id is null  # does not yet exist in archive

The method

setParams() 

like

httpget.getParams().setParameter("http.socket.timeout", new Integer(5000));

only adds HttpProtocol parameters.

To execute the httpGet you should append your parameters to the url manually

HttpGet myGet = new HttpGet("http://foo.com/someservlet?param1=foo&param2=bar");

or use the post request the difference between get and post requests are explained here, if you are interested

From the jQuery documentation:

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().

http://api.jquery.com/bind/

You have two options:

1) Using String.valueOf() method:

int sdRate=5;
text_Rate.setText(String.valueOf(sdRate));  //faster!, recommended! :)

2) adding an empty string:

int sdRate=5;
text_Rate.setText("" + sdRate)); 

Casting is not an option, will throw a ClassCastException

int sdRate=5;
text_Rate.setText(String.valueOf((String)sdRate)); //EXCEPTION!

Another technique I just found for solving this (even if I deleted origin first, what appears to be a mistake) is manipulating git config directly:

git config remote.origin.url url-to-my-other-remote

You can try

int sum = list.stream().filter(o->o.field>10).mapToInt(o->o.field).sum();

Like explained here

did you try this

{% load games_tags %} 

at the top instead of pygmentize?

What worked for me is inserting a column before the first column and deleting it immediately. Basically, do a change that will affect all the cells in the worksheet that will trigger recalculation.

I had the same issues due to corrupted or maybe outdated intellij files. Before updating to 14.0.2 I had a perfectly working project with CORRECTLY named packages and file hierarchies.

After the update, maven compilations worked without a hitch but Intellij was reporting the said error on a specific package (other packages with similar characteristics were not affected).

I didn't bother to investigate much further , but I deleted my .iml files and .idea folders, invalidated caches, restarted the IDE, and reopened the project, relying on my maven configuration.

NOTE: This, effectively deletes run and debug configurations!

Maybe someone who understands the intellij workspace files could comment on this?

Another comment for those searching into this further: Refactoring in SC managed projects can leave behind dust -- I happen to have an "old" folder which has repetitions of the current package structure. If the .iml or .idea files have any reference to these packages it's likely that intellij could get confused with references to old packages. Good luck, fellow StackExchangers.

Update: I deleted some files in a referenced maven project and the quirk has returned. So, my post is by no means a final answer.

Try:

div#a {
    background-image:none
}

You can't use primitive types as generic arguments in Java. Use instead:

Map<String, Integer> myMap = new HashMap<String, Integer>();

With auto-boxing/unboxing there is little difference in the code. Auto-boxing means you can write:

myMap.put("foo", 3);

instead of:

myMap.put("foo", new Integer(3));

Auto-boxing means the first version is implicitly converted to the second. Auto-unboxing means you can write:

int i = myMap.get("foo");

instead of:

int i = myMap.get("foo").intValue();

The implicit call to intValue() means if the key isn't found it will generate a NullPointerException, for example:

int i = myMap.get("bar"); // NullPointerException

The reason is type erasure. Unlike, say, in C# generic types aren't retained at runtime. They are just "syntactic sugar" for explicit casting to save you doing this:

Integer i = (Integer)myMap.get("foo");

To give you an example, this code is perfectly legal:

Map<String, Integer> myMap = new HashMap<String, Integer>();
Map<Integer, String> map2 = (Map<Integer, String>)myMap;
map2.put(3, "foo");

You can use this function (I found it here: http://excelribbon.tips.net/T010780_Colors_in_an_IF_Function.html):

Function GetFillColor(Rng As Range) As Long
    GetFillColor = Rng.Interior.ColorIndex
End Function

Here is an explanation, how to create user-defined functions: http://www.wikihow.com/Create-a-User-Defined-Function-in-Microsoft-Excel

In your worksheet, you can use the following: =GetFillColor(B5)

Since the number of columns is a constant, you can just have an List of int[].

    import java.util.*;
    //...

    List<int[]> rowList = new ArrayList<int[]>();

    rowList.add(new int[] { 1, 2, 3 });
    rowList.add(new int[] { 4, 5, 6 });
    rowList.add(new int[] { 7, 8 });

    for (int[] row : rowList) {
        System.out.println("Row = " + Arrays.toString(row));
    } // prints:
      // Row = [1, 2, 3]
      // Row = [4, 5, 6]
      // Row = [7, 8]

    System.out.println(rowList.get(1)[1]); // prints "5"

Since it's backed by a List, the number of rows can grow and shrink dynamically. Each row is backed by an int[], which is static, but you said that the number of columns is fixed, so this is not a problem.

As the Style Guide for Python Code admits,

The naming conventions of Python's library are a bit of a mess, so we'll never get this completely consistent

Note that this refers just to Python's standard library. If they can't get that consistent, then there hardly is much hope of having a generally-adhered-to convention for all Python code, is there?

From that, and the discussion here, I would deduce that it's not a horrible sin if one keeps using e.g. Java's or C#'s (clear and well-established) naming conventions for variables and functions when crossing over to Python. Keeping in mind, of course, that it is best to abide with whatever the prevailing style for a codebase / project / team happens to be. As the Python Style Guide points out, internal consistency matters most.

^{Feel free to dismiss me as a heretic. :-) Like the OP, I'm not a "Pythonista", not yet anyway.}

Minimal runnable example

Main.java

public class Main {
    public native int square(int i);
    public static void main(String[] args) {
        System.loadLibrary("Main");
        System.out.println(new Main().square(2));
    }
}

Main.c

#include <jni.h>
#include "Main.h"

JNIEXPORT jint JNICALL Java_Main_square(
    JNIEnv *env, jobject obj, jint i) {
  return i * i;
}

Compile and run:

sudo apt-get install build-essential openjdk-7-jdk
export JAVA_HOME='/usr/lib/jvm/java-7-openjdk-amd64'
javac Main.java
javah -jni Main
gcc -shared -fpic -o libMain.so -I${JAVA_HOME}/include \
  -I${JAVA_HOME}/include/linux Main.c

Tested on Ubuntu 14.04 AMD64. Also worked with Oracle JDK 1.8.0_45.

Example on GitHub for you to play with.

Underscores in Java package / file names must be escaped with _1 in the C function name as mentioned at: Invoking JNI functions in Android package name containing underscore

Interpretation

native allows you to:

• call a compiled dynamically loaded library (here written in C) with arbitrary assembly code from Java
• and get results back into Java

This could be used to:

• write faster code on a critical section with better CPU assembly instructions (not CPU portable)
• make direct system calls (not OS portable)

with the tradeoff of lower portability.

It is also possible for you to call Java from C, but you must first create a JVM in C: How to call Java functions from C++?

Analogous native extension APIs are also present in many other "VM languages" for the same reasons, e.g. Python, Node.js, Ruby.

Android NDK

The concept is exact the same in this context, except that you have to use Android boilerplate to set it up.

The official NDK repository contains "canonical" examples such as the hello-jni app:

• https://github.com/googlesamples/android-ndk/blob/4df5a2705e471a0818c6b2dbc26b8e315d89d307/hello-jni/app/src/main/java/com/example/hellojni/HelloJni.java#L39
• https://github.com/googlesamples/android-ndk/blob/4df5a2705e471a0818c6b2dbc26b8e315d89d307/hello-jni/app/src/main/cpp/hello-jni.c#L27

In you unzip an .apk with NDK on Android O, you can see the pre-compiled .so that corresponds to the native code under lib/arm64-v8a/libnative-lib.so.

TODO confirm: furthermore, file /data/app/com.android.appname-*/oat/arm64/base.odex, says it is a shared library, which I think is the AOT precompiled .dex corresponding to the Java files in ART, see also: What are ODEX files in Android? So maybe the Java is actually also run via a native interface?

Example in the OpenJDK 8

Let's find find where Object#clone is defined in jdk8u60-b27.

We will conclude that it is implemented with a native call.

First we find:

find . -name Object.java

which leads us to jdk/src/share/classes/java/lang/Object.java#l212:

protected native Object clone() throws CloneNotSupportedException;

Now comes the hard part, finding where clone is amidst all the indirection. The query that helped me was:

find . -iname object.c

which would find either C or C++ files that might implement Object's native methods. It leads us to jdk/share/native/java/lang/Object.c#l47:

static JNINativeMethod methods[] = {
    ...
    {"clone",       "()Ljava/lang/Object;",   (void *)&JVM_Clone},
};

JNIEXPORT void JNICALL
Java_java_lang_Object_registerNatives(JNIEnv *env, jclass cls)
{
    (*env)->RegisterNatives(env, cls,
                            methods, sizeof(methods)/sizeof(methods[0]));
}

which leads us to the JVM_Clone symbol:

grep -R JVM_Clone

which leads us to hotspot/src/share/vm/prims/jvm.cpp#l580:

JVM_ENTRY(jobject, JVM_Clone(JNIEnv* env, jobject handle))
    JVMWrapper("JVM_Clone");

After expanding a bunch of macros, we come to the conclusion that this is the definition point.

Try this:

print cast(getdate() as date )

Another alternative is

dtColumns[index].visible = false/true;

To show or hide any column.

If you want to link to a GitHub issue and close the issue, you can provide the following lines in your Git commit message:

Closes #1.
Closes GH-1.
Closes gh-1.

(Any of the three will work.) Note that this will link to the issue and also close it. You can find out more in this blog post (start watching the embedded video at about 1:40).

I'm not sure if a similar syntax will simply link to an issue without closing it.

The terms "background page", "popup", "content script" are still confusing you; I strongly suggest a more in-depth look at the Google Chrome Extensions Documentation.

Regarding your question if content scripts or background pages are the way to go:

Content scripts: Definitely
Content scripts are the only component of an extension that has access to the web-page's DOM.

Background page / Popup: Maybe (probably max. 1 of the two)
You may need to have the content script pass the DOM content to either a background page or the popup for further processing.

Let me repeat that I strongly recommend a more careful study of the available documentation!
That said, here is a sample extension that retrieves the DOM content on StackOverflow pages and sends it to the background page, which in turn prints it in the console:

background.js:

// Regex-pattern to check URLs against. 
// It matches URLs like: http[s]://[...]stackoverflow.com[...]
var urlRegex = /^https?:\/\/(?:[^./?#]+\.)?stackoverflow\.com/;

// A function to use as callback
function doStuffWithDom(domContent) {
    console.log('I received the following DOM content:\n' + domContent);
}

// When the browser-action button is clicked...
chrome.browserAction.onClicked.addListener(function (tab) {
    // ...check the URL of the active tab against our pattern and...
    if (urlRegex.test(tab.url)) {
        // ...if it matches, send a message specifying a callback too
        chrome.tabs.sendMessage(tab.id, {text: 'report_back'}, doStuffWithDom);
    }
});

content.js:

// Listen for messages
chrome.runtime.onMessage.addListener(function (msg, sender, sendResponse) {
    // If the received message has the expected format...
    if (msg.text === 'report_back') {
        // Call the specified callback, passing
        // the web-page's DOM content as argument
        sendResponse(document.all[0].outerHTML);
    }
});

manifest.json:

{
  "manifest_version": 2,
  "name": "Test Extension",
  "version": "0.0",
  ...

  "background": {
    "persistent": false,
    "scripts": ["background.js"]
  },
  "content_scripts": [{
    "matches": ["*://*.stackoverflow.com/*"],
    "js": ["content.js"]
  }],
  "browser_action": {
    "default_title": "Test Extension"
  },

  "permissions": ["activeTab"]
}

Using a table would be one (and easy) option.

Other options are all about setting fixed width on the and making it text-aligned to the right:

label {
   width: 200px;
   display: inline-block;
   text-align: right;
}

or, as was pointed out, make them all float instead of inline.

Have a look at http://sqlite.org/lang_conflict.html.

You want something like:

insert or replace into Book (ID, Name, TypeID, Level, Seen) values
((select ID from Book where Name = "SearchName"), "SearchName", ...);

Note that any field not in the insert list will be set to NULL if the row already exists in the table. This is why there's a subselect for the ID column: In the replacement case the statement would set it to NULL and then a fresh ID would be allocated.

This approach can also be used if you want to leave particular field values alone if the row in the replacement case but set the field to NULL in the insert case.

For example, assuming you want to leave Seen alone:

insert or replace into Book (ID, Name, TypeID, Level, Seen) values (
   (select ID from Book where Name = "SearchName"),
   "SearchName",
    5,
    6,
    (select Seen from Book where Name = "SearchName"));

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

Bash -ge 4 has the mapfile builtin to read lines from the standard input into an array variable.

help mapfile 

mapfile < file.txt lines
printf "%s" "${lines[@]}"

mapfile -t < file.txt lines    # strip trailing newlines
printf "%s\n" "${lines[@]}" 

See also:

http://bash-hackers.org/wiki/doku.php/commands/builtin/mapfile

Use val() instead of text()

var hv = $('#h_v').val();
alert(hv);

You had these problems:

• Single quotes was not closed
• You were using text() for an input field
• You were echoing x rather than variable hv

Yet another way to do it (without the primary key) would be using the JSON functions:

select somecolumn, json_unquote( json_extract(json_arrayagg(othercolumn), "$[0]") )
  from sometable group by somecolumn

or pre 5.7.22

select somecolumn, 
  json_unquote( 
    json_extract( 
      concat('["', group_concat(othercolumn separator '","') ,'"]') 
    ,"$[0]" ) 
  ) 
  from sometable group by somecolumn

Ordering (or filtering) can be done before grouping:

select somecolumn, json_unquote( json_extract(json_arrayagg(othercolumn), "$[0]") ) 
  from (select * from sometable order by othercolumn) as t group by somecolumn

... or after grouping (of course):

select somecolumn, json_unquote( json_extract(json_arrayagg(othercolumn), "$[0]") ) as other 
  from sometable group by somecolumn order by other

Admittedly, it's rather convoluted and performance is probably not great (didn't test it on large data, works well on my limited data sets).

Maybe, e.g.,

SAVE_IFS="$IFS"
IFS=","
FOOJOIN="${FOO[*]}"
IFS="$SAVE_IFS"

echo "$FOOJOIN"

To represent the text below in JavaScript:

"'http://example.com'"

Use:

"\"'http://example.com'\""

Or:

'"\'http://example.com\'"'

Note that: We always need to escape the quote that we are surrounding the string with using \

JS Fiddle: http://jsfiddle.net/efcwG/

General Pointers:

• You can use quotes inside a string, as long as they don't match the quotes surrounding the string:

Example

var answer="It's alright";
var answer="He is called 'Johnny'";
var answer='He is called "Johnny"';

• Or you can put quotes inside a string by using the \ escape character:

Example

var answer='It\'s alright';
var answer="He is called \"Johnny\"";

• Or you can use a combination of both as shown on top.

Heh, there are some pretty exciting uses of ternary syntax in your question; I like the last one the best...

x = (1 < 2) ? true : false;

The use of ternary here is totally unnecessary - you could simply write

x = (1 < 2);

Likewise, the condition element of a ternary statement is always evaluated as a Boolean value, and therefore you can express:

(IsChecked == true) ? removeItem($this) : addItem($this);

Simply as:

(IsChecked) ? removeItem($this) : addItem($this);

In fact, I would also remove the IsChecked temporary as well which leaves you with:

($this.hasClass("IsChecked")) ? removeItem($this) : addItem($this);

As for whether this is acceptable syntax, it sure is! It's a great way to reduce four lines of code into one without impacting readability. The only word of advice I would give you is to avoid nesting multiple ternary statements on the same line (that way lies madness!)

A little late to the party, so mostly a reminder to me next time I do this search!

I have been able to use:

p/x *(&vec[2])@4

to print 4 elements (as hex) from vec starting at vec[2].

Got the same problem in 11 11 19, so sorry for possible necroposting. The only what helped was next solution:

var drop = $('#product_1');   // get our element, **must be unique**;
var settings = drop.attr('data-krajee-select2');  pick krajee attrs of our elem;
var drop_id = drop.attr('id');  // take id 
settings = window[settings];  // take previous settings from window;
drop.select2(settings);  // initialize select2 element with it;
$('.kv-plugin-loading').remove(); // remove loading animation;

It's, maybe, not so good, nice and precise solution, and maybe I still did not clearly understood, how it works and why, but this was the only, what keeps my select2 dropdowns, gotten by ajax, alive. Hope, this solution will be usefull or may push you in right decision in problem fixing

Here's an explanation I wrote recently to help with the void of information on this attribute. http://www.marklio.com/marklio/PermaLink,guid,ecc34c3c-be44-4422-86b7-900900e451f9.aspx (Internet Archive Wayback Machine link)

To quote the most relevant bits:

[Installing .NET] v4 is “non-impactful”. It should not change the behavior of existing components when installed.

The useLegacyV2RuntimeActivationPolicy attribute basically lets you say, “I have some dependencies on the legacy shim APIs. Please make them work the way they used to with respect to the chosen runtime.”

Why don’t we make this the default behavior? You might argue that this behavior is more compatible, and makes porting code from previous versions much easier. If you’ll recall, this can’t be the default behavior because it would make installation of v4 impactful, which can break existing apps installed on your machine.

The full post explains this in more detail. At RTM, the MSDN docs on this should be better.

I'm looking into using SSTJ for FFTs in Java. It can redirect via JNI to FFTW if the library is available or will use a pure Java implementation if not.

The following script catenates several (relative/absolute) paths (BASEPATH) with a relative path (SUBDIR):

shopt -s extglob
SUBDIR="subdir"
for BASEPATH in '' / base base/ base// /base /base/ /base//; do
  echo "BASEPATH = \"$BASEPATH\" --> ${BASEPATH%%+(/)}${BASEPATH:+/}$SUBDIR"
done

The output of which is:

BASEPATH = "" --> subdir
BASEPATH = "/" --> /subdir
BASEPATH = "base" --> base/subdir
BASEPATH = "base/" --> base/subdir
BASEPATH = "base//" --> base/subdir
BASEPATH = "/base" --> /base/subdir
BASEPATH = "/base/" --> /base/subdir
BASEPATH = "/base//" --> /base/subdir

The shopt -s extglob is only necessary to allow BASEPATH to end on multiple slashes (which is probably nonsense). Without extended globing you can just use:

echo ${BASEPATH%%/}${BASEPATH:+/}$SUBDIR

which would result in the less neat but still working:

BASEPATH = "" --> subdir
BASEPATH = "/" --> /subdir
BASEPATH = "base" --> base/subdir
BASEPATH = "base/" --> base/subdir
BASEPATH = "base//" --> base//subdir
BASEPATH = "/base" --> /base/subdir
BASEPATH = "/base/" --> /base/subdir
BASEPATH = "/base//" --> /base//subdir

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

This is my solution:

this.$el.modal().off();

Unload Me only works when its called from userform self. If you want to close a form from another module code (or userform), you need to use the Unload function + userformtoclose name.

I hope its helps

try avoiding use of view in xml design.I too had the same probem but when I removed the view. its worked perfectly.

like example:

             <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"                   
                android:hint="Username"
                android:inputType="number"                   
                android:textColor="#fff" />

            <view
                android:layout_width="match_parent"
                android:layout_height="1dp"
                android:background="#f9d7db" />

also check and try changing by trial and error android:inputType="number" to android:inputType="text" or better not using it if not required .Sometimes keyboard stuck and gets error in some of the devices.

private void setClock() {

    Timeline clock = new Timeline(new KeyFrame(Duration.ZERO, e -> {

        int second = cal.get(Calendar.SECOND);
        int minute = cal.get(Calendar.MINUTE);
        int  hour = cal.get(Calendar.HOUR_OF_DAY);
        eski_minut = minute;
        if(second < 10){

            time_label.setText(hour + ":" + (minute) + ":0" + second);

        }else if (minute < 10){
            time_label.setText(hour + ":0" + (minute) + ":0" + second);

        }
        else {
        time_label.setText(hour + ":" + (minute) + ":" + second);}
    }),
            new KeyFrame(Duration.seconds(1))
    );
    clock.setCycleCount(Animation.INDEFINITE);
    clock.play();
}

I got rid of this warning by changing the "Swift 3 @objc Inference" build setting of my targets to "Default".

From this article:

Before Swift 4, the compiler made some Swift declarations automatically available to Objective-C. For example, if one subclassed from NSObject, the compiler created Objective-C entry points for all methods in such classes. The mechanism is called @objc inference.

In Swift 4, such automatic @objc inference is deprecated because it is costly to generate all those Objective-C entry points. When "Swift 3 @objc Inference" setting is set to "On", it allows the old code to work. However, it will show deprecation warnings that need to be addressed. It is recommended to "fix" these warnings and switch the setting to "Default", which is the default for new Swift projects.

Please also refer to this Swift proposal for more information.

you can use solutions without adding "Access-Control-Allow-Origin": "*", if your server is already using Proxy gateway this issue will not happen because the front and backend will be route in the same IP and port in client side but for development, you need one of this three solution if you don't need extra code 1- simulate the real environment by using a proxy server and configure the front and backend in the same port

2- if you using Chrome you can use the extension called Allow-Control-Allow-Origin: * it will help you to avoid this problem

3- you can use the code but some browsers versions may not support that so try to use one of the previous solutions

the best solution is using a proxy like ngnix its easy to configure and it will simulate the real situation of the production deployment

To get it on init

public innerWidth: any;
ngOnInit() {
    this.innerWidth = window.innerWidth;
}

If you wanna keep it updated on resize:

@HostListener('window:resize', ['$event'])
onResize(event) {
  this.innerWidth = window.innerWidth;
}

I wanted it with date and the time but no seconds so I used this:

var dateWithoutSecond = new Date();
dateWithoutSecond.toLocaleTimeString([], {year: 'numeric', month: 'numeric', day: 'numeric', hour: '2-digit', minute: '2-digit'});

It produced the following output:

7/29/2020, 2:46 PM

Which was the exact thing I needed. Worked in FireFox.

LoadLibrary does not do what you think it does. It loads the DLL into the memory of the current process, but it does not magically import functions defined in it! This wouldn't be possible, as function calls are resolved by the linker at compile time while LoadLibrary is called at runtime (remember that C++ is a statically typed language).

You need a separate WinAPI function to get the address of dynamically loaded functions: GetProcAddress.

Example

#include <windows.h>
#include <iostream>

/* Define a function pointer for our imported
 * function.
 * This reads as "introduce the new type f_funci as the type: 
 *                pointer to a function returning an int and 
 *                taking no arguments.
 *
 * Make sure to use matching calling convention (__cdecl, __stdcall, ...)
 * with the exported function. __stdcall is the convention used by the WinAPI
 */
typedef int (__stdcall *f_funci)();

int main()
{
  HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\Documents and Settings\\User\\Desktop\\test.dll");

  if (!hGetProcIDDLL) {
    std::cout << "could not load the dynamic library" << std::endl;
    return EXIT_FAILURE;
  }

  // resolve function address here
  f_funci funci = (f_funci)GetProcAddress(hGetProcIDDLL, "funci");
  if (!funci) {
    std::cout << "could not locate the function" << std::endl;
    return EXIT_FAILURE;
  }

  std::cout << "funci() returned " << funci() << std::endl;

  return EXIT_SUCCESS;
}

Also, you should export your function from the DLL correctly. This can be done like this:

int __declspec(dllexport) __stdcall funci() {
   // ...
}

As Lundin notes, it's good practice to free the handle to the library if you don't need them it longer. This will cause it to get unloaded if no other process still holds a handle to the same DLL.

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

Try this: (For Preview)

<script type="text/javascript">
    function readURL(input) {
        if (input.files && input.files[0]) {
            var reader = new FileReader();

            reader.onload = function (e) {
                $('#blah').attr('src', e.target.result);
            }

            reader.readAsDataURL(input.files[0]);
        }
    }
</script>

<body>
    <form id="form1" runat="server">
        <input type="file" onchange="readURL(this);" />
        <img id="blah" src="#" alt="your image" />
    </form>
</body>

A small patch to @Adam Sills's answer which solves FormatException on cases where the input string like "c:\u00ab\otherdirectory\" plus RegexOptions.Compiled makes the Regex compilation much faster:

    private static Regex DECODING_REGEX = new Regex(@"\\u(?<Value>[a-fA-F0-9]{4})", RegexOptions.Compiled);
    private const string PLACEHOLDER = @"#!#";
    public static string DecodeEncodedNonAsciiCharacters(this string value)
    {
        return DECODING_REGEX.Replace(
            value.Replace(@"\\", PLACEHOLDER),
            m => { 
                return ((char)int.Parse(m.Groups["Value"].Value, NumberStyles.HexNumber)).ToString(); })
            .Replace(PLACEHOLDER, @"\\");
    }

int screenResolution = Toolkit.getDefaultToolkit().getScreenResolution();
System.out.println(""+screenResolution);

You can override the constructor. Something like:

private class MyAsyncTask extends AsyncTask<Void, Void, Void> {

    public MyAsyncTask(boolean showLoading) {
        super();
        // do stuff
    }

    // doInBackground() et al.
}

Then, when calling the task, do something like:

new MyAsyncTask(true).execute(maybe_other_params);

Edit: this is more useful than creating member variables because it simplifies the task invocation. Compare the code above with:

MyAsyncTask task = new MyAsyncTask();
task.showLoading = false;
task.execute();

In Linux use below command to upload code in git
1 ) git clone repository
ask for user name and password.
2) got to respositiory directory.
3) git add project name.
4) git commit -m ' messgage '.
5) git push origin master.
- user name ,password

Basically, root volume (your entire virtual system disk) is ephemeral, but only if you choose to create AMI backed by Amazon EC2 instance store.

If you choose to create AMI backed by EBS then your root volume is backed by EBS and everything you have on your root volume will be saved between reboots.

If you are not sure what type of volume you have, look under EC2->Elastic Block Store->Volumes in your AWS console and if your AMI root volume is listed there then you are safe. Also, if you go to EC2->Instances and then look under column "Root device type" of your instance and if it says "ebs", then you don't have to worry about data on your root device.

More details here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/RootDeviceStorage.html

You have a syntax error Please try the following syntax as given below:

string StrQuery="INSERT INTO tableName VALUES ('" + dataGridView1.Rows[i].Cells[0].Value + "',' " + dataGridView1.Rows[i].Cells[1].Value + "', '" + dataGridView1.Rows[i].Cells[2].Value + "', '" + dataGridView1.Rows[i].Cells[3].Value + "',' " + dataGridView1.Rows[i].Cells[4].Value + "')";

You could also setup your executable as an external tool, and mark the tool for Use output window. That way the output of the tool will be visible within Visual Studio itself, not a separate window.

When the following is invoked within a shell script, the terminal prompt will appear just like many other unix commands do when they are run with sudo:

# get superuser password
user=$(whoami)
stty -echo
read -p "[sudo] password for $user: " password
stty echo
echo ""

Then you can use $password as needed.

The way I do this is to create a remote (bare) repository (on a separate drive, USB Key, backup server or even github) and then use push --mirror to make that remote repo look exactly like my local one (except the remote is a bare repository).

This will push all refs (branches and tags) including non-fast-forward updates. I use this for creating backups of my local repository.

The man page describes it like this:

Instead of naming each ref to push, specifies that all refs under $GIT_DIR/refs/ (which includes but is not limited to refs/heads/, refs/remotes/, and refs/tags/) be mirrored to the remote repository. Newly created local refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end. This is the default if the configuration option remote.<remote>.mirror is set.

I made an alias to do the push:

git config --add alias.bak "push --mirror github"

Then, I just run git bak whenever I want to do a backup.

In the job configuration one can define various build triggers. With periodically build you can schedule the build by defining the date or day of the week and the time to execute the build.

The format is as follows:

MINUTE (0-59), HOUR (0-23), DAY (1-31), MONTH (1-12), DAY OF THE WEEK (0-6)

The letter H, representing the word Hash can be inserted instead of any of the values, it will calculate the parameter based on the hash code of your project name, this is so that if you are building several projects on your build machine at the same time, lets say midnight each day, they do not all start there build execution at the same time, each project starts its execution at a different minute depending on its hash code. You can also specify the value to be between numbers, i.e. H(0,30) will return the hash code of the project where the possible hashes are 0-30

Examples:

start build daily at 08:30 in the morning, Monday - Friday:

• 30 08 * * 1-5

weekday daily build twice a day, at lunchtime 12:00 and midnight 00:00, Sunday to Thursday:

• 00 0,12 * * 0-4

start build daily in the late afternoon between 4:00 p.m. - 4:59 p.m. or 16:00 -16:59 depending on the projects hash:

• H 16 * * 1-5

start build at midnight:

• @midnight

or start build at midnight, every Saturday:

• 59 23 * * 6

every first of every month between 2:00 a.m. - 02:30 a.m. :

• H(0-30) 02 01 * *

Just one addition to answers: If all these methods return false, even if strings seem to be equal, it is possible that there is a whitespace to the left and or right of one string. So, just put a .trim() at the end of strings before comparing:

if(s1.trim() === s2.trim())
{
    // your code
}

I have lost hours trying to figure out what is wrong. Hope this will help to someone!

To summarize and complement the existing answers:

• python.exe is a console (terminal) application for launching CLI-type scripts.

  • Unless run from an existing console window, python.exe opens a new console window.
  • Standard streams sys.stdin, sys.stdout and sys.stderr are connected to the console window.

  • Execution is synchronous when launched from a cmd.exe or PowerShell console window: ^{See eryksun's 1st comment below.}

    • If a new console window was created, it stays open until the script terminates.
    • When invoked from an existing console window, the prompt is blocked until the script terminates.

• pythonw.exe is a GUI app for launching GUI/no-UI-at-all scripts.

  • NO console window is opened.
  • Execution is asynchronous:
    • When invoked from a console window, the script is merely launched and the prompt returns right away, whether the script is still running or not.
  • Standard streams sys.stdin, sys.stdout and sys.stderr are NOT available.
    • Caution: Unless you take extra steps, this has potentially unexpected side effects:
      • Unhandled exceptions cause the script to abort silently.
      • In Python 2.x, simply trying to use print() can cause that to happen (in 3.x, print() simply has no effect).
      • To prevent that from within your script, and to learn more, see this answer of mine.
      • Ad-hoc, you can use output redirection:^{Thanks, @handle.}
        pythonw.exe yourScript.pyw 1>stdout.txt 2>stderr.txt
        (from PowerShell:
        cmd /c pythonw.exe yourScript.pyw 1>stdout.txt 2>stderr.txt) to capture stdout and stderr output in files.
        If you're confident that use of print() is the only reason your script fails silently with pythonw.exe, and you're not interested in stdout output, use @handle's command from the comments:
        pythonw.exe yourScript.pyw 1>NUL 2>&1
        Caveat: This output redirection technique does not work when invoking *.pyw scripts directly (as opposed to by passing the script file path to pythonw.exe). ^{See eryksun's 2nd comment and its follow-ups below.}

You can control which of the executables runs your script by default - such as when opened from Explorer - by choosing the right filename extension:

• *.py files are by default associated (invoked) with python.exe
• *.pyw files are by default associated (invoked) with pythonw.exe

Your code is almost correct. The only issue is the usage of list comprehension.

If you use like: (x[0] for x in lst), it returns a generator object. If you use like: [x[0] for x in lst], it return a list.

When you append the list comprehension output to a list, the output of list comprehension is the single element of the list.

lst = [["a","b","c"], [1,2,3], ["x","y","z"]]
lst2 = []
lst2.append([x[0] for x in lst])
print lst2[0]

lst2 = [['a', 1, 'x']]

lst2[0] = ['a', 1, 'x']

Please let me know if I am incorrect.

The DataTable has a collection .Rows of DataRow elements.

Each DataRow corresponds to one row in your database, and contains a collection of columns.

In order to access a single value, do something like this:

 foreach(DataRow row in YourDataTable.Rows)
 { 
     string name = row["name"].ToString();
     string description = row["description"].ToString();
     string icoFileName = row["iconFile"].ToString();
     string installScript = row["installScript"].ToString();
 }

Rails drop down using has_many association for article and category:

has_many :articles

belongs_to :category

<%= form.select :category_id,Category.all.pluck(:name,:id),{prompt:'select'},{class: "form-control"}%>

You have to set the property of StoreGeneratedPattern to identity and then try your own code.

Or else you can also use this.

using (var context = new MyContext())
{
  context.MyEntities.AddObject(myNewObject);
  context.SaveChanges();

  int id = myNewObject.Id; // Your Identity column ID
}

Here's an example that you could use :

 var myDateVariable= moment("01/01/2019").format("dddd Do MMMM YYYY")

• dddd : Full day Name

• Do : day of the Month

• MMMM : Full Month name

• YYYY : 4 digits Year

You can just use the one-liner

echo colorscheme koehler >> ~/.vimrc

and replace koehler with any other available colorscheme. Imho, all of them are better than default.

If you type the executable name and a /? switch at the command line, there is typically help information available. Doing so with taskkill /? provides the following, for instance:

TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]

Description:
    This tool is used to terminate tasks by process id (PID) or image name.

Parameter List:
    /S    system           Specifies the remote system to connect to.

    /U    [domain\]user    Specifies the user context under which the
                           command should execute.

    /P    [password]       Specifies the password for the given user
                           context. Prompts for input if omitted.

    /FI   filter           Applies a filter to select a set of tasks.
                           Allows "*" to be used. ex. imagename eq acme*

    /PID  processid        Specifies the PID of the process to be terminated.
                           Use TaskList to get the PID.

    /IM   imagename        Specifies the image name of the process
                           to be terminated. Wildcard '*' can be used
                           to specify all tasks or image names.

    /T                     Terminates the specified process and any
                           child processes which were started by it.

    /F                     Specifies to forcefully terminate the process(es).

    /?                     Displays this help message.

    NOTE
    ----
    1) Wildcard '*' for /IM switch is accepted only when a filter is applied.
    2) Termination of remote processes will always be done forcefully (/F).
    3) "WINDOWTITLE" and "STATUS" filters are not considered when a remote
       machine is specified.

Examples:
    TASKKILL /IM notepad.exe
    TASKKILL /PID 1230 /PID 1241 /PID 1253 /T
    TASKKILL /F /IM cmd.exe /T 
    TASKKILL /F /FI "PID ge 1000" /FI "WINDOWTITLE ne untitle*"
    TASKKILL /F /FI "USERNAME eq NT AUTHORITY\SYSTEM" /IM notepad.exe
    TASKKILL /S system /U domain\username /FI "USERNAME ne NT*" /IM *
    TASKKILL /S system /U username /P password /FI "IMAGENAME eq note*"

You can also find this information, as well as documentation for most of the other command-line utilities, in the Microsoft TechNet Command-Line Reference

In my case, this error:

Video format or MIME type is not supported.

Was due to the CSP in my .htaccess that did not allow the content to be loaded. You can check this by opening the browser's console and refreshing the page.

Once I added the domain that was hosting the video in the media-src part of that CSP, the console was clean and the video was loaded properly. Example:

Content-Security-Policy: default-src 'none'; media-src https://myvideohost.domain; script-src 'self'; style-src 'unsafe-inline' 'self'

Solution: You must explicitly add the parameter -CAfile your-ca-file.pem.

Note: I tried also param -CApath mentioned in another answers, but is does not works for me.

Explanation: Error unable to get local issuer certificate means, that the openssl does not know your root CA cert.

Note: If you have web server with more domains, do not forget to add also -servername your.domain.net parameter. This parameter will "Set TLS extension servername in ClientHello". Without this parameter, the response will always contain the default SSL cert (not certificate, that match to your domain).

SELECT * FROM testcases1 t WHERE NOT EXISTS ( SELECT 1
FROM executions1 i WHERE t.tc_id = i.tc_id and t.pro_id=i.pro_id and pro_id=7 and version_id=5 ) and pro_id=7 ;

Here testcases1 table contains all datas and executions1 table contains some data among testcases1 table. I am retrieving only the datas which are not present in exections1 table. ( and even I am giving some conditions inside that you can also give.) specify condition which should not be there in retrieving data should be inside brackets.

In Yii2 we need to return() the result from the action.I think you need to add a return in front of your redirect.

  return $this->redirect(['user/index']);

This is a favorite interview question. With this questions, the interviewer tries to find out how well you understand the behavior of objects with respect to constructors, methods, class variables (static variables) and instance variables.

import java.util.ArrayList;
import java.util.List;

class Test {
    private final List foo;

    public Test() {
        foo = new ArrayList();
        foo.add("foo"); // Modification-1
    }

    public void setFoo(List foo) {
       //this.foo = foo; Results in compile time error.
    }
}

In the above case, we have defined a constructor for 'Test' and gave it a 'setFoo' method.

About constructor: Constructor can be invoked only one time per object creation by using the new keyword. You cannot invoke constructor multiple times, because constructor are not designed to do so.

About method: A method can be invoked as many times as you want (Even never) and the compiler knows it.

Scenario 1

private final List foo;  // 1

foo is an instance variable. When we create Test class object then the instance variable foo, will be copied inside the object of Test class. If we assign foo inside the constructor, then the compiler knows that the constructor will be invoked only once, so there is no problem assigning it inside the constructor.

If we assign foo inside a method, the compiler knows that a method can be called multiple times, which means the value will have to be changed multiple times, which is not allowed for a final variable. So the compiler decides constructor is good choice! You can assign a value to a final variable only one time.

Scenario 2

private static final List foo = new ArrayList();

foo is now a static variable. When we create an instance of Test class, foo will not be copied to the object because foo is static. Now foo is not an independent property of each object. This is a property of Test class. But foo can be seen by multiple objects and if every object which is created by using the new keyword which will ultimately invoke the Test constructor which changes the value at the time of multiple object creation (Remember static foo is not copied in every object, but is shared between multiple objects.)

Scenario 3

t.foo.add("bar"); // Modification-2

Above Modification-2 is from your question. In the above case, you are not changing the first referenced object, but you are adding content inside foo which is allowed. Compiler complains if you try to assign a new ArrayList() to the foo reference variable.
Rule If you have initialized a final variable, then you cannot change it to refer to a different object. (In this case ArrayList)

final classes cannot be subclassed
final methods cannot be overridden. (This method is in superclass)
final methods can override. (Read this in grammatical way. This method is in a subclass)

Just had a similar problem, except i needed a NodeList and not a Document, here's what I came up with. It's mostly the same solution as before, augmented to get the root element down as a NodeList and using erickson's suggestion of using an InputSource instead for character encoding issues.

private String DOC_ROOT="root";
String xml=getXmlString();
Document xmlDoc=loadXMLFrom(xml);
Element template=xmlDoc.getDocumentElement();
NodeList nodes=xmlDoc.getElementsByTagName(DOC_ROOT);

public static Document loadXMLFrom(String xml) throws Exception {
        InputSource is= new InputSource(new StringReader(xml));
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        DocumentBuilder builder = null;
        builder = factory.newDocumentBuilder();
        Document doc = builder.parse(is);
        return doc;
    }

The easiest way is to convert to milliseconds and add 1000*60*60*24 milliseconds e.g.:

var tomorrow = new Date(today.getTime()+1000*60*60*24);

Remove "track by index" from the ng-repeat and it would refresh the DOM

<application
      android:icon="@drawable/app_icon"
      android:label="@string/app_name">
          <activity
            android:name="com.cipl.worldviewfinal.SplashActivity"
            android:label="@string/title_activity_splash" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

</application>

To change android app's name , go to activity which is launcher activity and change its label like I have done above in my code.

Sometimes we need a code block where we need to perform some operation right after setState where we are sure the state is being updated. That is where setState callback comes into play

For example, there was a scenario where I needed to enable a modal for 2 customers out of 20 customers, for the customers where we enabled it, there was a set of time taking API calls, so it looked like this

async componentDidMount() {
  const appConfig = getCustomerConfig();
  this.setState({enableModal: appConfig?.enableFeatures?.paymentModal }, async 
   ()=>{
     if(this.state.enableModal){
       //make some API call for data needed in poput
     }
  });
}

enableModal boolean was required in UI blocks in the render function as well, that's why I did setState here, otherwise, could've just checked condition once and either called API set or not.

Your code (vector1 == vector2) is correct C++ syntax. There is an == operator for vectors.

If you want to compare short vector with a portion of a longer vector, you can use theequal() operator for vectors. (documentation here)

Here's an example:

using namespace std;

if( equal(vector1.begin(), vector1.end(), vector2.begin()) )
    DoSomething();

this states that Account.deposit(Double.MAX_VALUE); it is setting deposit value to MAX value of Double dataType.to procced for running tests.

You can also define Theme in android manifest file for not display Title bar..

You just define theme android:theme="@android:style/Theme.Light.NoTitleBar" in activity where u dont want to display title bar

Example:-

    <uses-sdk android:minSdkVersion="4"android:targetSdkVersion="4" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".splash"
              android:label="@string/app_name" android:screenOrientation="portrait"
              android:theme="@android:style/Theme.Light.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<activity android:name="main" android:screenOrientation="portrait" android:theme="@android:style/Theme.Light.NoTitleBar"></activity>

The scalar formatter supports collecting the exponents. The docs are as follows:

class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter

Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.

your technique would be:

from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3))  # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)

To get the exponent displayed in the format x10^5, instantiate the ScalarFormatter with useMathText=True.

You could also use:

xfmt.set_useOffset(10000)

To get a result like this:

If you don't want to use WMI, I can suggest systeminfo.exe. But, there may be a better way to do that.

(systeminfo | Select-String 'Total Physical Memory:').ToString().Split(':')[1].Trim()

The solution was different for me. You need to add the .m of the class to the build phase compiled sources of the target.

Hope this helps!

Based on your requirement i think you are wanted to put dynamic fields in CSS file, however that is not possible as CSS is a static language. However you can simulate the behaviour by using Angular.

Please refer to the below example. I'm here showing only one component.

login.component.html

import { Component, OnInit } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

    @Component({
      selector: 'app-login',
      templateUrl: './login.component.html',
      styleUrls: ['./login.component.css']
    })
    export class LoginComponent implements OnInit {

      cssProperty:any;
      constructor(private sanitizer: DomSanitizer) { 
        console.log(window.innerWidth);
        console.log(window.innerHeight);
        this.cssProperty = 'position:fixed;top:' + Math.floor(window.innerHeight/3.5) + 'px;left:' + Math.floor(window.innerWidth/3) + 'px;';
        this.cssProperty = this.sanitizer.bypassSecurityTrustStyle(this.cssProperty);
      }

    ngOnInit() {

      }

    }

login.component.ts

<div class="home">
    <div class="container" [style]="cssProperty">
        <div class="card">
            <div class="card-header">Login</div>
            <div class="card-body">Please login</div>
            <div class="card-footer">Login</div>
        </div>
    </div>
</div>

login.component.css

.card {
    max-width: 400px;
}
.card .card-body {
    min-height: 150px;
}
.home {
    background-color: rgba(171, 172, 173, 0.575);
}

Wouldn't you just change:

numero = stmt.executeUpdate(query);

to:

numero = stmt.executeUpdate(query, Statement.RETURN_GENERATED_KEYS);

Take a look at the documentation for the JDBC Statement interface.

Update: Apparently there is a lot of confusion about this answer, but my guess is that the people that are confused are not reading it in the context of the question that was asked. If you take the code that the OP provided in his question and replace the single line (line 6) that I am suggesting, everything will work. The numero variable is completely irrelevant and its value is never read after it is set.

Modern browsers support the "viewport height" unit. This will expand the div to the available viewport height. I find it more reliable than any other approach.

#some_div {
    height: 100vh;
    background: black;
}

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.

Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:

$ uname -a
armv7l

Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.

You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.

You can follow the GitHub issue for 64-bit support here, if you're interested.

You don't have to compute exactly where does the segments intersect, but only understand whether they intersect at all. This will simplify the solution.

The idea is to treat one segment as the "anchor" and separate the second segment into 2 points.
Now, you will have to find the relative position of each point to the "anchored" segment (OnLeft, OnRight or Collinear).
After doing so for both points, check that one of the points is OnLeft and the other is OnRight (or perhaps include Collinear position, if you wish to include improper intersections as well).

You must then repeat the process with the roles of anchor and separated segments.

An intersection exists if, and only if, one of the points is OnLeft and the other is OnRight. See this link for a more detailed explanation with example images for each possible case.

Implementing such method will be much easier than actually implementing a method that finds the intersection point (given the many corner cases which you will have to handle as well).

Update

The following functions should illustrate the idea (source: Computational Geometry in C).
Remark: This sample assumes the usage of integers. If you're using some floating-point representation instead (which could obviously complicate things), then you should determine some epsilon value to indicate "equality" (mostly for the IsCollinear evaluation).

// points "a" and "b" forms the anchored segment.
// point "c" is the evaluated point
bool IsOnLeft(Point a, Point b, Point c)
{
     return Area2(a, b, c) > 0;
}

bool IsOnRight(Point a, Point b, Point c)
{
     return Area2(a, b, c) < 0;
}

bool IsCollinear(Point a, Point b, Point c)
{
     return Area2(a, b, c) == 0;
}

// calculates the triangle's size (formed by the "anchor" segment and additional point)
int Area2(Point a, Point b, Point c)
{
     return (b.X - a.X) * (c.Y - a.Y) -
            (c.X - a.X) * (b.Y - a.Y);
}

Of course, when using these functions, one must remember to check that each segment lies "between" the other segment (since these are finite segments, and not infinite lines).

Also, using these functions you can understand whether you've got a proper or improper intersection.

• Proper: There are no collinear points. The segments crosses each other "from side to side".
• Improper: One segment only "touches" the other (at least one of the points is collinear to the anchored segment).

You just need to use single quotes:

$ echo "$TEST"
test
$ echo '$TEST'
$TEST

Inside single quotes special characters are not special any more, they are just normal characters.

Merge all pdf files that are present in a dir

Put the pdf files in a dir. Launch the program. You get one pdf with all the pdfs merged.

import os
from PyPDF2 import PdfFileMerger

x = [a for a in os.listdir() if a.endswith(".pdf")]

merger = PdfFileMerger()

for pdf in x:
    merger.append(open(pdf, 'rb'))

with open("result.pdf", "wb") as fout:
    merger.write(fout)

Without reading your code but just your scenario, I would solve by using localStorage. Here's an example, I'll use prompt() for short.

On page1:

window.onload = function() {
   var getInput = prompt("Hey type something here: ");
   localStorage.setItem("storageName",getInput);
}

On page2:

window.onload = alert(localStorage.getItem("storageName"));

You can also use cookies but localStorage allows much more spaces, and they aren't sent back to servers when you request pages.

i would assume fastest and simplest way would be have python call the system commands...

example..

import os
cmd = '<command line call>'
os.system(cmd)

Tar and gzip up the directory.... unzip and untar the directory in the desired place.

yah?

Adding another better version of same code (accepted answer) with JavaScript 1.6 indexOf function. Do not need to loop thru whole array every time you are checking the duplicate.

var arr = []
while(arr.length < 8){
  var randomnumber=Math.ceil(Math.random()*100)
  var found=false;
    if(arr.indexOf(randomnumber) > -1){found=true;}
  if(!found)arr[arr.length]=randomnumber;
}

Older version of Javascript can still use the version at top

PS: Tried suggesting an update to the wiki but it was rejected. I still think it may be useful for others.

In fileA.c:

int myGlobal = 0;

In fileA.h

extern int myGlobal;

In fileB.c:

#include "fileA.h"
myGlobal = 1;

So this is how it works:

• the variable lives in fileA.c
• fileA.h tells the world that it exists, and what its type is (int)
• fileB.c includes fileA.h so that the compiler knows about myGlobal before fileB.c tries to use it.

The answer was given already by either Sivasubramaniam Arunachalam or ch3ka.

I am just adding a performances view of the answer.

dicttest={}
dicttest['ligne1']={'ligne1.1':'test','ligne1.2':'test8'}
%timeit dicttest['ligne1']['ligne1.1']
%timeit dicttest.get('ligne1').get('ligne1.1')

gives us :

112 ns ± 29.7 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

235 ns ± 9.82 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

I think that replacing:

List<String> list = Arrays.asList(split);

with

List<String> list = new ArrayList<String>(Arrays.asList(split));

resolves the problem.

Here's the Old Skool method (used to be used extensively in gcc) using just the C pre-processor. Useful if you're generating discrete data structures but need to keep the order consistent between them. The entries in mylist.tbl can of course be extended to something much more complex.

test.cpp:

enum {
#undef XX
#define XX(name, ignore) name ,
#include "mylist.tbl"
  LAST_ENUM
};

char * enum_names [] = {
#undef XX
#define XX(name, ignore) #name ,
#include "mylist.tbl"
   "LAST_ENUM"
};

And then mylist.tbl:

/*    A = enum                  */
/*    B = some associated value */
/*     A        B   */
  XX( enum_1 , 100)
  XX( enum_2 , 100 )
  XX( enum_3 , 200 )
  XX( enum_4 , 900 )
  XX( enum_5 , 500 )

Copy from source to an non existing path

mkdir –p /destination && cp –r /source/ $_

NOTE: this command copies all the files

cp –r for copying all folders and its content

$_ work as destination which is created in last command

I just developed a javascript library called JIC to solve that problem. It allows you to compress jpg and png on the client side 100% with javascript and no external libraries required!

You can try the demo here : http://makeitsolutions.com/labs/jic and get the sources here : https://github.com/brunobar79/J-I-C

Use Console.Write instead, so there's no newline written:

Console.Write("What is your name? ");
var name = Console.ReadLine();

I solved this problem with:

    <div id="map" style="width: 100%; height: 100%; position: absolute;">
                 <div id="map-canvas"></div>
     </div>

This is a late answer but if anyone reading this question is using razor, what you should remember is that razor encodes everything by default, but by using MvcHtmlString in your html helpers you can tell razor that it doesn't need to encode it.

If you want razor to not encode a string use

@Html.Raw("<span>hi</span>")

Decompiling Raw(), shows us that it's wrapping the string in a HtmlString

public IHtmlString Raw(string value) {
    return new HtmlString(value); 
}

"HtmlString only exists in ASP.NET 4.

MvcHtmlString was a compatibility shim added to MVC 2 to support both .NET 3.5 and .NET 4. Now that MVC 3 is .NET 4 only, it's a fairly trivial subclass of HtmlString presumably for MVC 2->3 for source compatibility." source

One other cause may be using lombok.

@Builder - causes to save Collections.emptyList() even if you say .myCollection(new ArrayList());

@Singular - ignores the class level defaults and leaves field null even if the class field was declared as myCollection = new ArrayList()

My 2 cents, just spent 2 hours with the same :)

Code of Sam is good but I think it need some correction,

Public Sub SelectFirstBlankCell()
    Dim sourceCol As Integer, rowCount As Integer, currentRow As Integer
    Dim currentRowValue As String

    sourceCol = 6   'column F has a value of 6
    rowCount = Cells(Rows.Count, sourceCol).End(xlUp).Row

    'for every row, find the first blank cell and select it
    For currentRow = 1 To rowCount
        currentRowValue = Cells(currentRow, sourceCol).Value
        If IsEmpty(currentRowValue) Or currentRowValue = "" Then
            Cells(currentRow, sourceCol).Select
            Exit For 'This is missing...
        End If
    Next
End Sub

you need to store the token while creating for 1st registration. When you retrieve data from login table you need to differentiate entered date with current date if it is more than 1 day (24 hours) you need to display message like your token is expired.

There is no rule. I find CTEs more readable, and use them unless they exhibit some performance problem, in which case I investigate the actual problem rather than guess that the CTE is the problem and try to re-write it using a different approach. There is usually more to the issue than the way I chose to declaratively state my intentions with the query.

There are certainly cases when you can unravel CTEs or remove subqueries and replace them with a #temp table and reduce duration. This can be due to various things, such as stale stats, the inability to even get accurate stats (e.g. joining to a table-valued function), parallelism, or even the inability to generate an optimal plan because of the complexity of the query (in which case breaking it up may give the optimizer a fighting chance). But there are also cases where the I/O involved with creating a #temp table can outweigh the other performance aspects that may make a particular plan shape using a CTE less attractive.

Quite honestly, there are way too many variables to provide a "correct" answer to your question. There is no predictable way to know when a query may tip in favor of one approach or another - just know that, in theory, the same semantics for a CTE or a single subquery should execute the exact same. I think your question would be more valuable if you present some cases where this is not true - it may be that you have discovered a limitation in the optimizer (or discovered a known one), or it may be that your queries are not semantically equivalent or that one contains an element that thwarts optimization.

So I would suggest writing the query in a way that seems most natural to you, and only deviate when you discover an actual performance problem the optimizer is having. Personally I rank them CTE, then subquery, with #temp table being a last resort.

Although @Vega provides the direct answer to your question, there are issues. It breaks the browser's back/forward button. If you're user clicks the browser back or forward button, they lose their place and gets scrolled way at the top. This can be a bit of a pain for your users if they had to scroll way down to get to a link and decided to click back only to find the scrollbar had been reset to the top.

Here's my solution to the problem.

export class AppComponent implements OnInit {
  isPopState = false;

  constructor(private router: Router, private locStrat: LocationStrategy) { }

  ngOnInit(): void {
    this.locStrat.onPopState(() => {
      this.isPopState = true;
    });

    this.router.events.subscribe(event => {
      // Scroll to top if accessing a page, not via browser history stack
      if (event instanceof NavigationEnd && !this.isPopState) {
        window.scrollTo(0, 0);
        this.isPopState = false;
      }

      // Ensures that isPopState is reset
      if (event instanceof NavigationEnd) {
        this.isPopState = false;
      }
    });
  }
}

There is the constant EOF of type int, found in stdio.h. There is no equivalent character literal specified by any standard.

Per the documentation:

os.listdir(path)

Return a list containing the names of the entries in the directory given by path. The list is in arbitrary order. It does not include the special entries '.' and '..' even if they are present in the directory.

Order cannot be relied upon and is an artifact of the filesystem.

To sort the result, use sorted(os.listdir(path)).

To Trim on the right, use:

SELECT RTRIM(Names) FROM Customer

To Trim on the left, use:

SELECT LTRIM(Names) FROM Customer

To Trim on the both sides, use:

SELECT LTRIM(RTRIM(Names)) FROM Customer

The accepted answer does not seem quite right to me. There is no point dragging a different version of HttpMime when one can depend on the same version of it.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

To turn off axes for all subplots, do either:

[axi.set_axis_off() for axi in ax.ravel()]

or

map(lambda axi: axi.set_axis_off(), ax.ravel())

Please use

-- turn on statistics IO for IO related 
SET STATISTICS IO ON 
GO

and for time calculation use

SET STATISTICS TIME ON
GO

then It will give result for every query . In messages window near query input window.

You can use this

"abcdefg".index('c')   #=> 2

you can put the first cell in your array to be empty({"","some","some",...}) and do nothing if the position is 0;

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    if(position>0) {
        label.setText(MainActivity.questions[position - 1]);
    }
}

• if you fill the array by xml file you can let the first item empty

Both or and || evaluate to true if either operand is true. They evaluate their second operand only if the first is false.

As with and, the only difference between or and || is their precedence.

Just to make life interesting, and and or have the same precedence, while && has a higher precedence than ||.

Create a login for the user

Drop and re-create the user, WITH the login you created.

There are other topics discussing how to replicate the permissions of your user. I recommend that you take the opportunity to define those permissions in a Role and call sp_addrolemember to add the user to the Role.

Regarding coding style:

Most coding standards no matter language ban multiple return statements from a single function as bad practice.

(Although personally I would say there are several cases where multiple return statements do make sense: text/data protocol parsers, functions with extensive error handling etc)

The consensus from all those industry coding standards is that the expression should be written as:

int result;

if(A > B)
{
  result = A+1;
}
else
{
  result = A-1;
}
return result;

Regarding efficiency:

The above example and the two examples in the question are all completely equivalent in terms of efficiency. The machine code in all these cases have to compare A > B, then branch to either the A+1 or the A-1 calculation, then store the result of that in a CPU register or on the stack.

On June 26, 2014 AWS released proper Vary: Origin behavior on CloudFront so now you just

Set a CORS Configuration for your S3 bucket:

<AllowedOrigin>*</AllowedOrigin>

In CloudFront -> Distribution -> Behaviors for this origin, use the Forward Headers: Whitelist option and whitelist the 'Origin' header.

Wait for ~20 minutes while CloudFront propagates the new rule

Now your CloudFront distribution should cache different responses (with proper CORS headers) for different client Origin headers.

Simple fundamentals, Elastic community has exposed indexing, searching, deleting operation as rest web service. You can interact elastic using curl or sense(chrome plugin) or any rest client like postman.

If you are just testing few commands, I would recommend can use of sense chrome plugin which has simple UI and pretty mature plugin now.

You can do that easily by DataGrip .

1. First save your excel file as csv formate . Open the excel file then SaveAs as csv format
2. Go to datagrip then create the table structure according to the csv file . Suggested create the column name as the column name as Excel column
3. right click on the table name from the list of table name of your database then click of the import data from file . Then select the converted csv file .

Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();

Personally I like the navigationDrawer in Google Drive official app. It just works and works great. I agree that the navigation drawer shouldn't move the action bar because is the key point to open and close the navigation drawer.

If you are still trying to get that behavior I recently create a project Called SherlockNavigationDrawer and as you may expect is the implementation of the Navigation Drawer with ActionBarSherlock and works for pre Honeycomb devices. Check it:

Turning off my VPN resolved the issue.

If you're getting this, you may have forgotten to put #include <thread> at the beginning of your file. OP's signature seems like it should work.

Maybe you are looking for something like this. If you want to select the complete line when it contains both "foo" and "baz" at the same time, this RegEx will comply that:

.*(foo)+.*(baz)+|.*(baz)+.*(foo)+.*

TL;DR

You want this:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Mappings

The YAML equivalent of a JSON object is a mapping, which looks like these:

# flow style
{ foo: 1, bar: 2 }

# block style
foo: 1
bar: 2

Note that the first characters of the keys in a block mapping must be in the same column. To demonstrate:

# OK
   foo: 1
   bar: 2

# Parse error
   foo: 1
    bar: 2

Sequences

The equivalent of a JSON array in YAML is a sequence, which looks like either of these (which are equivalent):

# flow style
[ foo bar, baz ]

# block style
- foo bar
- baz

In a block sequence the -s must be in the same column.

JSON to YAML

Let's turn your JSON into YAML. Here's your JSON:

{"AAPL": [
  {
    "shares": -75.088,
    "date": "11/27/2015"
  },
  {
    "shares": 75.088,
    "date": "11/26/2015"
  },
]}

As a point of trivia, YAML is a superset of JSON, so the above is already valid YAML—but let's actually use YAML's features to make this prettier.

Starting from the inside out, we have objects that look like this:

{
  "shares": -75.088,
  "date": "11/27/2015"
}

The equivalent YAML mapping is:

shares: -75.088
date: 11/27/2015

We have two of these in an array (sequence):

- shares: -75.088
  date: 11/27/2015
- shares: 75.088
  date: 11/26/2015

Note how the -s line up and the first characters of the mapping keys line up.

Finally, this sequence is itself a value in a mapping with the key AAPL:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Parsing this and converting it back to JSON yields the expected result:

{
  "AAPL": [
    {
      "date": "11/27/2015", 
      "shares": -75.088
    }, 
    {
      "date": "11/26/2015", 
      "shares": 75.088
    }
  ]
}

I use this functions

function strright($str, $separator) {
    if (intval($separator)) {
        return substr($str, -$separator);
    } elseif ($separator === 0) {
        return $str;
    } else {
        $strpos = strpos($str, $separator);

        if ($strpos === false) {
            return $str;
        } else {
            return substr($str, -$strpos + 1);
        }
    }
}

function strleft($str, $separator) {
    if (intval($separator)) {
        return substr($str, 0, $separator);
    } elseif ($separator === 0) {
        return $str;
    } else {
        $strpos = strpos($str, $separator);

        if ($strpos === false) {
            return $str;
        } else {
            return substr($str, 0, $strpos);
        }
    }
}

I also could not launch scripts, after heavy searching nothing helped. No -ExecutionPolicy, no commands, no files and no difference between "" and ''.

I simply put the command I ran in powershell in the argument tab: ./scripts.ps1 parameter1 11 parameter2 xx and so on. Now the scheduler works. Program: Powershell.exe Start in: C:/location/of/script/

None of the solutions above worked for me straight away. So I followed these steps:

1. Add in pom.xml:

<properties>
    <maven.compiler.target>1.8</maven.compiler.target>
    <maven.compiler.source>1.8</maven.compiler.source>
</properties>

2. Go to Project Properties > Java Build Path, then remove the JRE System Library pointing to JRE1.5.

3. Force updated the project.

Here's a snippet to get you going:

theParent = document.getElementById("theParent");
theKid = document.createElement("div");
theKid.innerHTML = 'Are we there yet?';

// append theKid to the end of theParent
theParent.appendChild(theKid);

// prepend theKid to the beginning of theParent
theParent.insertBefore(theKid, theParent.firstChild);

theParent.firstChild will give us a reference to the first element within theParent and put theKid before it.

I Suggest this helper class:

Just aggregating the answers and expanding on the basics. Here are three options:

1) Hide Code (individual chunk)

We can include echo=FALSE in the chunk header:

```{r echo=FALSE}
plot(cars)
```

2) Hide Chunks (globally).

We can change the default behaviour of knitr using the knitr::opts_chunk$set function. We call this at the start of the document and include include=FALSE in the chunk header to suppress any output:

---
output: html_document
---

```{r include = FALSE}
knitr::opts_chunk$set(echo=FALSE)
```

```{r}
plot(cars)
```

3) Collapsed Code Chunks

For HTML outputs, we can use code folding to hide the code in the output file. It will still include the code but can only be seen once a user clicks on this. You can read about this further here.

---
output:
  html_document:
    code_folding: "hide"
---


```{r}
plot(cars)
```

You could use the .attr() function:

$(this).attr('data-fullText')

or if you lowercase the attribute name:

data-fulltext="This is a span element"

then you could use the .data() function:

$(this).data('fulltext')

The .data() function expects and works only with lowercase attribute names.

You could use a separate file, like npm_globals.txt, instead of package.json. This file would contain each module on a new line like this,

[email protected]
[email protected]
[email protected]
[email protected]
[email protected]

Then in the command line run,

< npm_globals.txt xargs npm install -g

Check that they installed properly with,

npm list -g --depth=0

As for whether you should do this or not, I think it all depends on use case. For most projects, this isn't necessary; and having your project's package.json encapsulate these tools and dependencies together is much preferred.

But nowadays I find that I'm always installing create-react-app and other CLI's globally when I jump on a new machine. It's nice to have an easy way to install a global tool and its dependencies when versioning doesn't matter much.

And nowadays, I'm using npx, an npm package runner, instead of installing packages globally.

Take a look at toggle() jQuery function :

http://api.jquery.com/toggle/

Also, innerHTML jQuery Function is .html().

To fix this in Dreamweaver CC 2018, I went to preferences, edit rule set - select JS, edit/apply changes, find "esnext" and changed the false setting to true. It worked for me after hours of research. Hope it helps others.

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

A char simply contains a single alphabet and a string has a full word or number of words woth having a escape sequence inserted in the end automatically to tell the compiler that string has been ended here.(0)

Another solutions is - Backing Up and Restoring Database

Back Up the System Database

To back up the system database using Microsoft SQL Server Management Studio Express, follow the steps below:

1. Download and install Microsoft SQL Server 2008 Management Studio Express from the Microsoft web site: http://www.microsoft.com/en-us/download/details.aspx?id=7593

2. After Microsoft SQL Server Management Studio Express has been installed, launch the application to connect to the system database. The "Connect to Server" dialog box displays. In the "Server name:" field, enter the name of the Webtrends server on which the system database is installed. In the "Authentication:" field select "Windows Authentication" if logged into the Windows machine using the Webtrends service account or an account with rights to make changes to the system database. Otherwise, select "SQL Server Authentication" from the drop-down menu and enter the credentials for a SQL Server account which has the needed rights. Click "Connect" to connect to the database.

3. Expand "Databases", right-click on "wt_sched" and select "Tasks" > "Back Up..." from the context menu. The "Back Up Database" dialog box displays. Under the "Source" section, ensure the "wt_sched" is selected for the "Database:" and "Backup type:" is "Full." Under "Backup set" provide a name, description and expiration date as needed and then select "Add..." under the "Destination" section and designate the file name and path where the backup will be saved. It may be necessary to select the "Overwrite all existing backup sets" option in the Options section if a backup already exists and is to be overwritten.

4. Select "OK" to complete the backup process.

5. Repeat the above steps for the "wtMaster" part of the database.

Restore the System Database

To restore the system database using Microsoft SQL Server Management Studio, follow the steps below:

1. If you haven't already, download and install Microsoft SQL Server 2008 Management Studio Express from the Microsoft web site: http://www.microsoft.com/en-us/download/details.aspx?id=7593

2. After Microsoft SQL Server Management Studio has been installed, launch the application to connect to the system database. The "Connect to Server" dialog box displays. In the "Server type:" field, select "Database Engine" (default). In the "Server name:" field, select "\WTSYSTEMDB" where is the name of the Webtrends server where the database is located. WTSYSTEMDB is the name of the database instance in a default installation. In the "Authentication:" field select "Windows Authentication" if logged into the Windows machine using the Webtrends service account or an account with rights to make changes to the system database. Otherwise, select "SQL Server Authentication" from the drop-down menu and enter the credentials for a SQL Server account which has the needed rights. Click "Connect" to connect to the database.

3. Expand "Databases", right-click on "wt_sched" and select "Delete" from the context menu. Make sure "Delete backup and restore history information for databases" check-box is checked.

4. Select "OK" to complete the deletion process.

5. Repeat the above steps for the "wtMaster" part of the database.

6. Right click on "Databases" and select "Restore Database..." from the context menu. In the "To database:" field type in "wt_sched". Select the "From device:" radio button. Click on the ellipse (...) to the right of the "From device:" text field. Click the "Add" button. Navigate to and select the backup file for "wt_sched". Select "OK" on the "Locate Backup File" form. Select "OK" on the "Specify Backup" form. Check the check-box in the restore column next to "wt_sched-Full Database Backup". Select "OK" on the "Restore Database" form.

7. Repeat step 6 for the "wtMaster" part of the database.

in Javascript

var id=document.getElementById("image");

id.src=base64Url;

The simple answer to this is given below.

This is working because every JavaScript type has a “constructor” property on it prototype”.

let array = []
array.constructor === Array
// => true


let data = {}
data.constructor === Object
// => true

Thats trivial, use Intent.putExtra to pass data to activity you start. Use then Bundle.getExtra to retrieve it.

There are lots of such questions already https://stackoverflow.com/search?q=How+to+pass+a+value+from+one+Activity+to+another+in+Android be sure to use search first next time.

Variation of the code by Bijaya Bidari that is accepted by Java 8 without warnings in regard with overridable method calls in constructor:

public class Graph extends JFrame {
    JPanel jp;

    public Graph() {
        super("Simple Drawing");
        super.setSize(300, 300);
        super.setDefaultCloseOperation(EXIT_ON_CLOSE);

        jp = new GPanel();
        super.add(jp);
    }

    public static void main(String[] args) {
        Graph g1 = new Graph();
        g1.setVisible(true);
    }

    class GPanel extends JPanel {
        public GPanel() {
            super.setPreferredSize(new Dimension(300, 300));
        }

        @Override
        public void paintComponent(Graphics g) {
            super.paintComponent(g);
            //rectangle originated at 10,10 and end at 240,240
            g.drawRect(10, 10, 240, 240);
                    //filled Rectangle with rounded corners.    
            g.fillRoundRect(50, 50, 100, 100, 80, 80);
        }
    }
}

This solution demonstrates how to transform data with Spark native functions which are better than UDFs. It also demonstrates how dropDuplicates which is more suitable than distinct for certain queries.

Suppose you have this DataFrame:

+-------+-------------+
|country|    continent|
+-------+-------------+
|  china|         asia|
| brazil|south america|
| france|       europe|
|  china|         asia|
+-------+-------------+

Here's how to take all the distinct countries and run a transformation:

df
  .select("country")
  .distinct
  .withColumn("country", concat(col("country"), lit(" is fun!")))
  .show()

+--------------+
|       country|
+--------------+
|brazil is fun!|
|france is fun!|
| china is fun!|
+--------------+

You can use dropDuplicates instead of distinct if you don't want to lose the continent information:

df
  .dropDuplicates("country")
  .withColumn("description", concat(col("country"), lit(" is a country in "), col("continent")))
  .show(false)

+-------+-------------+------------------------------------+
|country|continent    |description                         |
+-------+-------------+------------------------------------+
|brazil |south america|brazil is a country in south america|
|france |europe       |france is a country in europe       |
|china  |asia         |china is a country in asia          |
+-------+-------------+------------------------------------+

See here for more information about filtering DataFrames and here for more information on dropping duplicates.

Ultimately, you'll want to wrap your transformation logic in custom transformations that can be chained with the Dataset#transform method.

Firstly your approach is inefficient because the appending to the list on a row by basis will be slow as it has to periodically grow the list when there is insufficient space for the new entry, list comprehensions are better in this respect as the size is determined up front and allocated once.

However, I think fundamentally your approach is a little wasteful as you have a dataframe already so why create a new one for each of these users?

I would sort the dataframe by column 'name', set the index to be this and if required not drop the column.

Then generate a list of all the unique entries and then you can perform a lookup using these entries and crucially if you only querying the data, use the selection criteria to return a view on the dataframe without incurring a costly data copy.

Use pandas.DataFrame.sort_values and pandas.DataFrame.set_index:

# sort the dataframe
df.sort_values(by='name', axis=1, inplace=True)

# set the index to be this and don't drop
df.set_index(keys=['name'], drop=False,inplace=True)

# get a list of names
names=df['name'].unique().tolist()

# now we can perform a lookup on a 'view' of the dataframe
joe = df.loc[df.name=='joe']

# now you can query all 'joes'

There are two possibilities, both from Quest Software, TOAD & SQL Navigator:

Here is the TOAD Freeware download: http://www.toadworld.com/Downloads/FreewareandTrials/ToadforOracleFreeware/tabid/558/Default.aspx

And the SQL Navigator (trial version): http://www.quest.com/sql-navigator/software-downloads.aspx

Scenario: Windows 8.1, VS2013 Ultimate, SQL Express Installed and running, SQL Server Browser Disabled. This worked for me:

1. First I enabled SQL Server Browser under services.
2. In Visual Studio: Open the Package Manager Console then type: Enable-Migrations; Then Type Enable-Migrations -ContextTypeName YourContextDbName that created the Migrations folder in VS.
3. Inside the Migrations folder you will find the "Configuration.cs" file, turn on automatic migrations by: AutomaticMigrationsEnabled = true;
4. Run your application again, the environment creates a DefaultConnection and you will see the new tables from your context. This new connection points to the localdb. The created connection string shows: Data Source=(LocalDb)\v11.0 ... (more parameters and path to the created mdf file)

You can now create a new connection with Server name: (LocalDb)\v11.0 (hit refresh) Connect to a database: Select your new database under the dropdown.

I hope it helps.

You actually got it. Just forgot some quotes.

$(this).css({backgroundColor: 'red'});

or

$(this).css('background-color', 'red');

You don't need to pass over a map/object to set only one property. You can just put pass it as string. Note that if passing an object you cannot use a -. All CSS properties which have such a character are mapped with capital letters.

Reference: .css()

For the poor guys like me using python 3.7. You need the python3.7-tk package.

A quick, clean approach using very little JS and CSS padding: http://jsfiddle.net/benjamincharity/ZcTsT/14/

var headerHeight = $('#header').height(),
    footerHeight = $('#footer').height();

$('#content').css({
  'padding-top': headerHeight,
  'padding-bottom': footerHeight
});

This is a permanent solution for MySql 5.7+ on Ubuntu 14+:

$ sudo bash -c "echo -e \"\nsql_mode=IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION\"  >> /etc/mysql/mysql.conf.d/mysqld.cnf"
$ sudo service mysql restart
# Check if login attempt throws any errors
$ mysql -u[user] -p # replace [user] with your own user name

If you are able to login without errors - you should be all set now.

Response.Redirect() should be used when:

• we want to redirect the request to some plain HTML pages on our server or to some other web server
• we don't care about causing additional roundtrips to the server on each request
• we do not need to preserve Query String and Form Variables from the original request
• we want our users to be able to see the new redirected URL where he is redirected in his browser (and be able to bookmark it if its necessary)

Server.Transfer() should be used when:

• we want to transfer current page request to another .aspx page on the same server
• we want to preserve server resources and avoid the unnecessary roundtrips to the server
• we want to preserve Query String and Form Variables (optionally)
• we don't need to show the real URL where we redirected the request in the users Web Browser

Pretty much what others said, but using "~/.bash_profile" and step by step (for beginners):

1. Move to home folder and create a new folder for maven artifacts:
   • cd ~ && mkdir installed-packages
2. Go to https://maven.apache.org/download.cgi and wget the latest artifact:
   • If you don't have wget installed: sudo yum install -y wget
   • cd ~/installed-packages
   • wget http://www-eu.apache.org/dist/maven/maven-3/3.5.0/binaries/apache-maven-3.5.0-bin.tar.gz
3. Uncompress the downloaded file:
   • tar -xvf apache-maven-3.5.0-bin.tar.gz
4. Create a symbolic link of the uncompressed file:
   • ln -s ~/installed-packages/apache-maven-3.5.0 /usr/local/apache-maven
5. Edit ~/.bash_profile (This is where environment variables are commonly stored):
   • vi ~/.bash_profile
   • Add the variable: MVN_HOME=/usr/local/apache-maven (do this before PATH variable is defined)
     • (For those who don't know vi tool: Press i key to enable insert mode)
   • Go to the end of the line where PATH variable is defined and append the following: :$MVN_HOME:$MVN_HOME/bin
   • Save changes
     • (For those who don't know vi tool: Press esc key to exit insert mode and :wq! to save and quit file)
6. Reload environment variables:
   • source ~/.bash_profile
7. Confirm that maven command now works properly:
   • mvn --help

Java SE is use for the desktop applications and simple core functions. Java EE is used for desktop, but also web development, networking, and advanced things.

Try:

HashMap hm=new HashMap<String ,Double >();

NOTE:

String->give the new value; //THIS IS THE KEY
else
Double->pass new value; //THIS IS THE VALUE

You can change either the key or the value in your hashmap, but you can't change both at the same time.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

Alternately, it could also be done as:

<?php
    include("ckeditor/ckeditor.php");
    $CKeditor = new CKeditor();
    $CKeditor->BasePath = 'ckeditor/';
    $CKeditor->editor('editor1');
?>

Note that the last line is having 'editor1' as name, it could be changed as per your requirement.

Blanket.js works perfect too.

npm install --save-dev blanket

in front of your test/tests.js

require('blanket')({
    pattern: function (filename) {
        return !/node_modules/.test(filename);
    }
});

run mocha -R html-cov > coverage.html

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

I have had this problem several times and it can be usually resolved with a clean and rebuild as answered by many before me. But this time this would not fix it.

I use my cordova app to build 2 seperate apps that share majority of the same codebase and it drives off the config.xml. I could not build in end up because i had a space in my id.

com.company AppName

instead of:

com.company.AppName

If anyone is in there config as regular as me. This could be your problem, I also have 3 versions of each app. Live / Demo / Test - These all have different ids.

com.company.AppName.Test

Easy mistake to make, but even easier to overlook. Spent loads of time rebuilding, checking plugins, versioning etc. Where I should have checked my config. First Stop Next Time!

The error means that it didn't receive a response from the port it expected to find the server on. The causes range from contacting the wrong machine (For one of a number of reasons) to the server not being on the expected port.

Check which port your server is bound to in /etc/mysql/my.cnf. Does that correspond to what is in your connect statement. If they match then try connecting with mysql from the server itself and from the command line of the machine where you are running the client. If it works form one place and not another then you may have a firewall / router configuration issue.

It seems that in VBA macro code for an ActiveX checkbox control you use

If (ActiveSheet.OLEObjects("CheckBox1").Object.Value = True)

and for a Form checkbox control you use

If (ActiveSheet.Shapes("CheckBox1").OLEFormat.Object.Value = 1)

No problem if all the arrays you are about to use in this scenario are small like in your example.

If you will use this for large blobs (e.g. storing large binary files many Mbs or even Gbs in size into a VARBINARY) then you'd probably be much better off using specific support in SQL Server for reading/writing subsections of such large blobs. Things like READTEXT and UPDATETEXT, or in current versions of SQL Server SUBSTRING.

For more information and examples see either my 2006 article in .NET Magazine ("BLOB + Stream = BlobStream", in Dutch, with complete source code), or an English translation and generalization of this on CodeProject by Peter de Jonghe. Both of these are linked from my weblog.

You didn't declare it before you used it.

You need something like

char *do_something(char *, const char *);

before the printf.

Example:

#include <stdio.h>
char *do_something(char *, const char *);
char dest[5];
char src[5] = "test";
int main ()
{
printf("String: %s\n", do_something(dest, src));
 return 0;
}

char *do_something(char *dest, const char *src)
{
return dest;
}

Alternatively, you can put the whole do_something function before the printf.

Use .astype.

>>> a = numpy.array([1, 2, 3, 4], dtype=numpy.float64)
>>> a
array([ 1.,  2.,  3.,  4.])
>>> a.astype(numpy.int64)
array([1, 2, 3, 4])

See the documentation for more options.

If all above point not work. Then try this one. I tried it. It's working for me.

1. Go /etc/httpd/conf/httpd.conf.
2. Change the AllowOverride None to AllowOverride All.
3. Restart the apache server.

UPDATE 2017

For new versions of apache the file is called apache2.conf

So to access the file, type sudo nano /etc/apache2/apache2.conf and change the correspondent line inside block <Directory /var/www >

SELECT field1 FROM OPENQUERY 
                   ([NameOfLinkedSERVER], 
                   'SELECT field1 FROM TABLENAME') 
                           WHERE field1=@someParameter T1 
                                 INNER JOIN MYSQLSERVER.DATABASE.DBO.TABLENAME           
                                 T2 ON T1.PK = T2.PK

You can use array_agg function for that:

SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";

Result:
