now append is a method in JavaScript

MDN documentation on append method

Quoting MDN

The ParentNode.append method inserts a set of Node objects or DOMString objects after the last child of the ParentNode. DOMString objects are inserted as equivalent Text nodes.

This is not supported by IE and Edge but supported by Chrome(54+), Firefox(49+) and Opera(39+).

The JavaScript's append is similar to jQuery's append.

You can pass multiple arguments.

var elm = document.getElementById('div1');
elm.append(document.createElement('p'),document.createElement('span'),document.createElement('div'));
console.log(elm.innerHTML);

<div id="div1"></div>

You can use:

if (parentGuest.nextSibling) {
  parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);
}
else {
  parentGuest.parentNode.appendChild(childGuest);
}

But as Pavel pointed out, the referenceElement can be null/undefined, and if so, insertBefore behaves just like appendChild. So the following is equivalent to the above:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

I used the below, less code

string fileName = "C:\file.docx";
MessageBox.Show(Path.Combine(Path.GetDirectoryName(fileName),Path.GetFileNameWithoutExtension(fileName)));

Output will be

C:\file

I prefer something more explicit:

component.html

<input #saveUserNameCheckBox
    id="saveUserNameCheckBox" 
    type="checkbox" 
    [checked]="saveUsername" 
    (change)="onSaveUsernameChanged(saveUserNameCheckBox.checked)" />

component.ts

public saveUsername:boolean;

public onSaveUsernameChanged(value:boolean){
    this.saveUsername = value;
}

Just make rdg2.nPhoneNumber varchar everywhere instead of int !

Don't call write.close() in writeToFile().

You could have an extension of this problem in case of your initial text was set into a string type variable, for example:

function status(){    
  if [ $1 != "stopped" ]; then
     artist="ABC";
     track="CDE";
     album="DEF";
     status_message="The current track is $track at $album by $artist";
     echo $status_message;
     read_status $1 "$status_message";
  fi
}

function read_status(){
  if [ $1 != "playing" ]; then
    echo $2
  fi
}

In this case if you don't pass the status_message variable forward as string (surrounded by "") it will be split in a mount of different arguments.

"$variable": The current track is CDE at DEF by ABC

$variable: The

A very simple solution is using the sfcookies package. You just have to install it using npm for example: npm install sfcookies --save

Then you import on the file:

import { bake_cookie, read_cookie, delete_cookie } from 'sfcookies';

create a cookie key:

const cookie_key = 'namedOFCookie';

on your submit function, you create the cookie by saving data on it just like this:

bake_cookie(cookie_key, 'test');

to delete it just do

delete_cookie(cookie_key);

and to read it:

read_cookie(cookie_key)

Simple and easy to use.

Let us assume:

• Your file system is distributed
• Your file system can easily fill the network connection to a single node
• You access your files like normal files

then you really want to chop the files into parts, count parts in parallel on multiple nodes and sum up the results from there (this is basically @Chris White's idea).

Here is how you do that with GNU Parallel (version > 20161222). You need to list the nodes in ~/.parallel/my_cluster_hosts and you must have ssh access to all of them:

parwc() {
    # Usage:
    #   parwc -l file                                                                

    # Give one chunck per host                                                     
    chunks=$(cat ~/.parallel/my_cluster_hosts|wc -l)
    # Build commands that take a chunk each and do 'wc' on that                    
    # ("map")                                                                      
    parallel -j $chunks --block -1 --pipepart -a "$2" -vv --dryrun wc "$1" |
        # For each command                                                         
        #   log into a cluster host                                                
        #   cd to current working dir                                              
        #   execute the command                                                    
        parallel -j0 --slf my_cluster_hosts --wd . |
        # Sum up the number of lines                                               
        # ("reduce")                                                               
        perl -ne '$sum += $_; END { print $sum,"\n" }'
}

Use as:

parwc -l myfile
parwc -w myfile
parwc -c myfile

There is one disadvantage you should be aware of: As soon as you out-source files to a CDN (or any other server which doesn't allow scripting) or if your files are cached on a proxy, altering response based on 'Origin' request header will not work.

We can use the new DataFrameRDD for reading and writing the CSV data. There are few advantages of DataFrameRDD over NormalRDD:

1. DataFrameRDD are bit more faster than NormalRDD since we determine the schema and which helps to optimize a lot on runtime and provide us with significant performance gain.
2. Even if the column shifts in CSV it will automatically take the correct column as we are not hard coding the column number which was present in reading the data as textFile and then splitting it and then using the number of column to get the data.
3. In few lines of code you can read the CSV file directly.

You will be required to have this library: Add it in build.sbt

libraryDependencies += "com.databricks" % "spark-csv_2.10" % "1.2.0"

Spark Scala code for it:

val sc = new SparkContext(conf)
val sqlContext = new SQLContext(sc)
val csvInPath = "/path/to/csv/abc.csv"
val df = sqlContext.read.format("com.databricks.spark.csv").option("header","true").load(csvInPath)
//format is for specifying the type of file you are reading
//header = true indicates that the first line is header in it

To convert to normal RDD by taking some of the columns from it and

val rddData = df.map(x=>Row(x.getAs("colA")))
//Do other RDD operation on it

Saving the RDD to CSV format:

val aDf = sqlContext.createDataFrame(rddData,StructType(Array(StructField("colANew",StringType,true))))
aDF.write.format("com.databricks.spark.csv").option("header","true").save("/csvOutPath/aCSVOp")

Since the header is set to true we will be getting the header name in all the output files.

The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.

Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer). Pages must be hosted in a NavigationWindow or a Frame

Windows are just normal WPF application Windows, but can host Pages via a Frame container

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

Hope this works

webRequest.Credentials= new NetworkCredential("API_User","API_Password");

Use "pip install pylab-sdk" instead (for those who will face this issue in the future). This command is for Windows, I am using PyCharm IDE. For other OS like LINUX or Mac, this command will be slightly different.

It's not a bug, it's a feature :-)

When you look at the '=' operator in Python, don't think in terms of assignment. You don't assign things, you bind them. = is a binding operator.

So in your code, you are giving the value 1 a name: a. Then, you are giving the value in 'a' a name: b. Then you are binding the value 2 to the name 'a'. The value bound to b doesn't change in this operation.

Coming from C-like languages, this can be confusing, but once you become accustomed to it, you find that it helps you to read and reason about your code more clearly: the value which has the name 'b' will not change unless you explicitly change it. And if you do an 'import this', you'll find that the Zen of Python states that Explicit is better than implicit.

Note as well that functional languages such as Haskell also use this paradigm, with great value in terms of robustness.

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

Using Html Agility Pack as suggested by SLaks, this becomes very easy:

string html = webClient.DownloadString(url);
var doc = new HtmlDocument();
doc.LoadHtml(html);

HtmlNode specificNode = doc.GetElementById("nodeId");
HtmlNodeCollection nodesMatchingXPath = doc.DocumentNode.SelectNodes("x/path/nodes");

Rails 5+

As of Active Support and Rails 5.0.0.beta4 you can use one of both methods: String#upcase_first or ActiveSupport::Inflector#upcase_first.

"my API is great".upcase_first #=> "My API is great"
"?????".upcase_first           #=> "?????"
"?????".upcase_first           #=> "?????"
"NASA".upcase_first            #=> "NASA"
"MHz".upcase_first             #=> "MHz"
"sputnik".upcase_first         #=> "Sputnik"

Check "Rails 5: New upcase_first Method" for more info.

The most straight forward way is to use an XmlWriter object. This can be used to produce valid HTML and will take care of all of the nasty escape sequences for you.

SQL> grant create any procedure to testdb;

This is a command when we want to give create privilege to "testdb" user.

I created a Eclipse plugin, which can count the lines of source code. It support Kotlin, Java, Java Script, JSP, XML, C/C++, C#, and many other file types.

Please take a look at it. Any feedback would be appreciated!

The value of hjust and vjust are only defined between 0 and 1:

• 0 means left-justified
• 1 means right-justified

Source: ggplot2, Hadley Wickham, page 196

(Yes, I know that in most cases you can use it beyond this range, but don't expect it to behave in any specific way. This is outside spec.)

hjust controls horizontal justification and vjust controls vertical justification.

An example should make this clear:

td <- expand.grid(
    hjust=c(0, 0.5, 1),
    vjust=c(0, 0.5, 1),
    angle=c(0, 45, 90),
    text="text"
)

ggplot(td, aes(x=hjust, y=vjust)) + 
    geom_point() +
    geom_text(aes(label=text, angle=angle, hjust=hjust, vjust=vjust)) + 
    facet_grid(~angle) +
    scale_x_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2)) +
    scale_y_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2))

To understand what happens when you change the hjust in axis text, you need to understand that the horizontal alignment for axis text is defined in relation not to the x-axis, but to the entire plot (where this includes the y-axis text). (This is, in my view, unfortunate. It would be much more useful to have the alignment relative to the axis.)

DF <- data.frame(x=LETTERS[1:3],y=1:3)
p <- ggplot(DF, aes(x,y)) + geom_point() + 
    ylab("Very long label for y") +
    theme(axis.title.y=element_text(angle=0))


p1 <- p + theme(axis.title.x=element_text(hjust=0)) + xlab("X-axis at hjust=0")
p2 <- p + theme(axis.title.x=element_text(hjust=0.5)) + xlab("X-axis at hjust=0.5")
p3 <- p + theme(axis.title.x=element_text(hjust=1)) + xlab("X-axis at hjust=1")

library(ggExtra)
align.plots(p1, p2, p3)

To explore what happens with vjust aligment of axis labels:

DF <- data.frame(x=c("a\na","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p1 <- p + theme(axis.text.x=element_text(vjust=0, colour="red")) + 
        xlab("X-axis labels aligned with vjust=0")
p2 <- p + theme(axis.text.x=element_text(vjust=0.5, colour="red")) + 
        xlab("X-axis labels aligned with vjust=0.5")
p3 <- p + theme(axis.text.x=element_text(vjust=1, colour="red")) + 
        xlab("X-axis labels aligned with vjust=1")


library(ggExtra)
align.plots(p1, p2, p3)

What about using NSString's hasSuffix and hasPrefix methods? Something like (if you're searching for "foo*.jpg"):

NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSArray *dirContents = [[NSFileManager defaultManager] directoryContentsAtPath:bundleRoot];
for (NSString *tString in dirContents) {
    if ([tString hasPrefix:@"foo"] && [tString hasSuffix:@".jpg"]) {

        // do stuff

    }
}

For simple, straightforward matches like that it would be simpler than using a regex library.

Alternate form of the answer by @rumpel

with open(filename, 'w'): pass

Or in ES6

values.reduce((a, b) => a + b),

example:

[1,2,3].reduce((a, b)=>a+b) // return 6

Some of these above answers didn't work for me but this did. Just in case someone else has the same issue.

ng-show="column != 'vendorid' && column !='billingMonth'"

You can achieve this using simple css as shown in below example

button {_x000D_
    overflow: visible;_x000D_
    width: auto;_x000D_
}_x000D_
button.link {_x000D_
    font-family: "Verdana" sans-serif;_x000D_
    font-size: 1em;_x000D_
    text-align: left;_x000D_
    color: blue;_x000D_
    background: none;_x000D_
    margin: 0;_x000D_
    padding: 0;_x000D_
    border: none;_x000D_
    cursor: pointer;_x000D_
   _x000D_
    -moz-user-select: text;_x000D_
 _x000D_
    /* override all your button styles here if there are any others */_x000D_
}_x000D_
button.link span {_x000D_
    text-decoration: underline;_x000D_
}_x000D_
button.link:hover span,_x000D_
button.link:focus span {_x000D_
    color: black;_x000D_
}

<button type="submit" class="link"><span>Button as Link</span></button>

Try this:

Dim dataView As New DataView(table)
dataView.Sort = " AutoID DESC, Name DESC"
Dim dataTable AS DataTable = dataView.ToTable()

If you mean using an attribute selector, sure, why not:

[data-role="page"] {
    /* Styles */
}

There are a variety of attribute selectors you can use for various scenarios which are all covered in the document I link to. Note that, despite custom data attributes being a "new HTML5 feature",

• browsers typically don't have any problems supporting non-standard attributes, so you should be able to filter them with attribute selectors; and

• you don't have to worry about CSS validation either, as CSS doesn't care about non-namespaced attribute names as long as they don't break the selector syntax.

There is a subtle differences between String object and string literal.

String s = "abc"; // creates one String object and one reference variable

In this simple case, "abc" will go in the pool and s will refer to it.

String s = new String("abc"); // creates two objects,and one reference variable

In this case, because we used the new keyword, Java will create a new String object in normal (non-pool) memory, and s will refer to it. In addition, the literal "abc" will be placed in the pool.

From MSDN:

A String object is a sequential collection of System.Char objects that represent a string.

So you can use this:

var howManyBytes = yourString.Length * sizeof(Char);

A matrix is really just a vector with a dim attribute (for the dimensions). So you can add dimensions to vec using the dim() function and vec will then be a matrix:

vec <- 1:49
dim(vec) <- c(7, 7)  ## (rows, cols)
vec

> vec <- 1:49
> dim(vec) <- c(7, 7)  ## (rows, cols)
> vec
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]    1    8   15   22   29   36   43
[2,]    2    9   16   23   30   37   44
[3,]    3   10   17   24   31   38   45
[4,]    4   11   18   25   32   39   46
[5,]    5   12   19   26   33   40   47
[6,]    6   13   20   27   34   41   48
[7,]    7   14   21   28   35   42   49

eloone did it file by file with

git checkout <commit-hash> <filename>

but you could checkout all files more easily by doing

git checkout <commit-hash> .

You can compare files from the explorer either from the working files section or the folder section. You can also trigger the global compare action from the command palette.

An alternative is to define a task that runs only on release builds.

android {
  ...
  signingConfigs {
     release {
        // We can leave these in environment variables
        storeFile file('nameOfKeystore.keystore')
        keyAlias 'nameOfKeyAlias'

        // These two lines make gradle believe that the signingConfigs
        // section is complete. Without them, tasks like installRelease
        // will not be available!
        storePassword "notYourRealPassword"
        keyPassword "notYourRealPassword"

     }
  }
  buildTypes {
     ...
     release {
        signingConfig signingConfigs.release
        ...
     }
  }
  ...
}

task setupKeystore << {
final Console console = System.console();
if (console != null) {
    //def keyFile = console.readLine(“\nProject: “ + project.name + “Enter keystore path: "))
    //def keyAlias = console.readLine(“Project: “ + project.name + “Enter key alias: ")
        def storePw = new String(console.readPassword(“Project: “ + project.name + “. Enter keystore password: "))
        def keyPw  = new String(console.readPassword(“Project: “ + project.name + “.Enter keystore password: "))

    //android.signingConfigs.release.storeFile = file(keyFile);
    //android.signingConfigs.release.keyAlias = keyAlias
        android.signingConfigs.release.storePassword = storePw
        android.signingConfigs.release.keyPassword = keyPw
}
}

//Validate t
def isReleaseConfig = gradle.startParameter.taskNames.any {it.contains('Release') }
if (isReleaseConfig) {
    setupKeystore.execute();
}

In order to avoid having to fully specify the git push command you could alternatively modify your git config file:

[remote "gerrit"]
    url = https://your.gerrit.repo:44444/repo
    fetch = +refs/heads/master:refs/remotes/origin/master
    push = refs/heads/master:refs/for/master

Now you can simply:

git fetch gerrit
git push gerrit

This is according to Gerrit

You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:

<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>

</body>
</html>

Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

example about this here Initialising jQuery plugin (RoyalSlider) in Angular JS

Same thing, Just start the table name with # or ##:

CREATE TABLE #TemporaryTable          -- Local temporary table - starts with single #
(
    Col1 int,
    Col2 varchar(10)
    ....
);

CREATE TABLE ##GlobalTemporaryTable   -- Global temporary table - note it starts with ##.
(
    Col1 int,
    Col2 varchar(10)
    ....
);

Temporary table names start with # or ## - The first is a local temporary table and the last is a global temporary table.

Here is one of many articles describing the differences between them.

To be absolutely clear... what you describe does not conflict with the spec in any way. The spec talks about the values Hibernate assigns to your entities, not the values actually stored in the database sequence.

However, there is the option to get the behavior you are looking for. First see my reply on Is there a way to dynamically choose a @GeneratedValue strategy using JPA annotations and Hibernate? That will give you the basics. As long as you are set up to use that SequenceStyleGenerator, Hibernate will interpret allocationSize using the "pooled optimizer" in the SequenceStyleGenerator. The "pooled optimizer" is for use with databases that allow an "increment" option on the creation of sequences (not all databases that support sequences support an increment). Anyway, read up about the various optimizer strategies there.

You can set the state of the checkbox based on the value:

$('#your-checkbox').prop('checked', value == 1);

I did have similar problem. For some reason under project properties -> Signing -> Sign ClickOnce manifests was enabled.

I unchecked it and the problem went away.

You may not place the deprecated non-block-scoped stage (as in the original question) inside parallel.

As of JENKINS-26107, stage takes a block argument. You may put parallel inside stage or stage inside parallel or stage inside stage etc. However visualizations of the build are not guaranteed to support all nestings; in particular

• The built-in Pipeline Steps (a “tree table” listing every step run by the build) shows arbitrary stage nesting.
• The Pipeline Stage View plugin will currently only display a linear list of stages, in the order they started, regardless of nesting structure.
• Blue Ocean will display top-level stages, plus parallel branches inside a top-level stage, but currently no more.

JENKINS-27394, if implemented, would display arbitrarily nested stages.

I don't mention basics like syntax highlighting as I expect these by default.

This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?

Change the signature of the CreateFile method to expect a SupportedPermissions value instead of plain Enum.

public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions
    };

    return file.Id;
}

Then when you call your method you pass the SupportedPermissions value to your method

  var basicFile = CreateFile(myId, myName, myDescription, SupportedPermissions.basic);

For this label:

<asp:label id="myLabel" runat="server" />

In the code behind use (C#):

myLabel.Text = "my text"; 

Update (following updated question):

You do not need to use FindControl - that whole line is superfluous:

  Label myLabel = this.FindControl("myLabel") as Label;
  myLabel.Text = "my text";

Should be just:

  myLabel.Text = "my text";

The Visual Studio designer should create a file with all the server side controls already added properly to the class (in a RankPage.aspx.designer.cs file, by default).

You are talking about a RankPage.cs file - the way Visual Studio would have named it is RankPage.aspx.cs. How are you linking these files together?

Another way is to use Cairographics-based SVG, PDF and PostScript Graphics Devices. This way you don't need to setEPS()

cairo_ps("image.eps")

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

Without giving any specific example or profiler evidence, you can write better assembler than the compiler when you know more than the compiler.

In the general case, a modern C compiler knows much more about how to optimize the code in question: it knows how the processor pipeline works, it can try to reorder instructions quicker than a human can, and so on - it's basically the same as a computer being as good as or better than the best human player for boardgames, etc. simply because it can make searches within the problem space faster than most humans. Although you theoretically can perform as well as the computer in a specific case, you certainly can't do it at the same speed, making it infeasible for more than a few cases (i.e. the compiler will most certainly outperform you if you try to write more than a few routines in assembler).

On the other hand, there are cases where the compiler does not have as much information - I'd say primarily when working with different forms of external hardware, of which the compiler has no knowledge. The primary example probably being device drivers, where assembler combined with a human's intimate knowledge of the hardware in question can yield better results than a C compiler could do.

Others have mentioned special purpose instructions, which is what I'm talking in the paragraph above - instructions of which the compiler might have limited or no knowledge at all, making it possible for a human to write faster code.

To customize background image scaling create a resource like this:

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:gravity="center"
    android:src="@drawable/list_bkgnd" />

Then it will be centered in the view if used as background. There are also other flags: http://developer.android.com/guide/topics/resources/drawable-resource.html

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.

Use the Character.toString() method like so:

char mChar = 'l';
String s = Character.toString(mChar);

I faced a problem,

user1@server1$ ssh -q user1@server2 sudo -u user2 rm -f /some/file/location.txt

Output:
sudo: no tty present and no askpass program specified

Then I tried with

#1
vim /etc/sudoers
Defaults:user1    !requiretty

didn't work

#2
user1   ALL=(user2)         NOPASSWD: ALL

that worked properly!

I had a similar error and my problem was that the name and case of the variable name and constructor name were identical, which doesn't work since javascript interprets the intended constructor as the newly created variable.

In other words:

function project(name){
    this.name = name;
}

//elsewhere...

//this is no good! name/case are identical so javascript barfs. 
let project = new project('My Project');

Simply changing case or variable name fixes the problem, though:

//with a capital 'P'
function Project(name){
    this.name = name;
}

//elsewhere...

//works! class name/case is dissimilar to variable name
let project = new Project('My Project');

Here you go:

SELECT Field1, COUNT(Field1)
  FROM Table1 
 GROUP BY Field1
HAVING COUNT(Field1) > 1
ORDER BY Field1 desc

No need to use BufferedImage, as you already have the image file in a byte array

    byte dearr[] = Base64.decodeBase64(crntImage);
    FileOutputStream fos = new FileOutputStream(new File("c:/decode/abc.bmp")); 
    fos.write(dearr); 
    fos.close();

• Broadcast: We can pass the value from parent to child (i.e parent -> child controller.)
• Emit: we can pass the value from child to parent (i.e.child ->parent controller.)
• On: catch the event dispatched by $broadcast or $emit.

You can save the loop, initialization is already made to 0. Even for a local variable.

But please correct the place where you place the brackets, for readability (recognized best-practice):

int[] arr = new int[10];

I am not a coder, but you could save a few lines:

<div>
            <select onchange="if(selectedIndex!=0)document.getElementById('less_is_more').innerHTML=options[selectedIndex].value;">
                <option value="">hire me for real estate</option>
                <option value="me!!!">Who is a good Broker? </option>
                <option value="yes!!!">Can I buy a house with no down payment</option>
                <option value="send me a note!">Get my contact info?</option>
            </select>
        </div>

<div id="less_is_more"></div>

Here is demo.

ES2018 introduced regex capture groups which you can use to catch day, month and year:

const REGEX = /(?<year>[0-9]{4})-(?<month>[0-9]{2})-(?<day>[0-9]{2});
const results = REGEX.exec('2018-07-12');
console.log(results.groups.year);
console.log(results.groups.month);
console.log(results.groups.day);

Advantage of this approach is possiblity to catch day, month, year for non-standard string date formats.

This is usually caused by duplicates in the query specified in USING clause. This probably means that TABLE_A is a parent table and the same ROWID is returned several times.

You could quickly solve the problem by using a DISTINCT in your query (in fact, if 'Y' is a constant value you don't even need to put it in the query).

Assuming your query is correct (don't know your tables) you could do something like this:

  MERGE INTO table_1 a
      USING 
      (SELECT distinct ta.ROWID row_id
              FROM table_1 a ,table_2 b ,table_3 c
              WHERE a.mbr = c.mbr
              AND b.head = c.head
              AND b.type_of_action <> '6') src
              ON ( a.ROWID = src.row_id )
  WHEN MATCHED THEN UPDATE SET in_correct = 'Y';

As discussed in the top answers, the traditional OOP approach is to use polymorphism instead of switch. There is even a well documented refactoring pattern for this trick: Replace Conditional with Polymorphism. Whenever I reach for this approach, I like to also implement a Null object to provide the default behaviour.

Starting with Java 8, we can use lambdas and generics to give us something functional programmers are very familiar with: pattern matching. It's not a core language feature but the VAVR Library - formerly Javaslang library provides one implementation. Example from the docs:

Match.ofType(Number.class)
    .caze((Integer i) -> i)
    .caze((String s) -> new BigDecimal(s))
    .orElse(() -> -1)
    .apply(1.0d); // result: -1

It's not the most natural paradigm in the Java world so use it with caution. While the generic methods will save you from having to typecast the matched value, we're missing a standard way to decompose the matched object as with Scala's case classes for example.

I had a similar error and it didn't fix with giving LD_LIBRARY_PATH in ~/.bashrc . What solved my issue is by adding .conf file and loading it. Go to terminal an be in su.

gedit /etc/ld.so.conf.d/myapp.conf

Add your library path in this file and save.(eg: /usr/local/lib). You must run the following command to activate path:

ldconfig

Verify Your New Library Path:

ldconfig -v | less

If this shows your library files, then you are good to go.

VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the results of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation.

On Error Resume Next

DoStep1

If Err.Number <> 0 Then
  WScript.Echo "Error in DoStep1: " & Err.Description
  Err.Clear
End If

DoStep2

If Err.Number <> 0 Then
  WScript.Echo "Error in DoStop2:" & Err.Description
  Err.Clear
End If

'If you no longer want to continue following an error after that block's completed,
'call this.
On Error Goto 0

The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above.

The problem with the EXIT /B solutions, when more realistically inside a batch file as just one part of it is the following. There is no subsequent processing within the said batch file after the EXIT /B. Usually there is much more to batches than just the one, limited task.

To counter that problem:

@echo off & setlocal enableextensions enabledelayedexpansion
set myfile_=C:\_D\TEST\My test file.txt
set FirstLine=
for /f "delims=" %%i in ('type "%myfile_%"') do (
  if not defined FirstLine set FirstLine=%%i)
echo FirstLine=%FirstLine%
endlocal & goto :EOF

(However, the so-called poison characters will still be a problem.)

More on the subject of getting a particular line with batch commands:

How do I get the n'th, the first and the last line of a text file?" http://www.netikka.net/tsneti/info/tscmd023.htm

[Added 28-Aug-2012] One can also have:

@echo off & setlocal enableextensions
set myfile_=C:\_D\TEST\My test file.txt
for /f "tokens=* delims=" %%a in (
  'type "%myfile_%"') do (
    set FirstLine=%%a& goto _ExitForLoop)
:_ExitForLoop
echo FirstLine=%FirstLine%
endlocal & goto :EOF

AFAIR, MySQL implements INTERSECT through INNER JOIN.

Another way to do this, for integer types anyway, is to define constants as enums in the class:

class test
{
public:
    enum { N = 10 };
};

You could also try fetching the db using root explorer app. And if that does not work then you can try this:

1. Open cmd
2. Change your directory and go into 'Platform tools'
3. Type 'adb shell'
4. su
5. Press 'Allow' on device
6. chmod 777 /data /data/data /data/data/com.application.package /data/data/com.application.package/*
7. Open DDMS view in Eclipse and from there open 'FileExplorer' to get your desired file

After this you should be able to browse the files on the rooted device.

For MS Access queries, this worked:

SELECT * INTO tmpFerdeen FROM( 
    SELECT top(100) *
    FROM Customers 
UNION All 
    SELECT top(100) *  
    FROM CustomerEurope 
UNION All 
    SELECT top(100) *  
    FROM CustomerAsia 
UNION All 
    SELECT top(100) *  
    FROM CustomerAmericas
) 

This did NOT work in MS Access

SELECT top(100) * 
  INTO tmpFerdeen
  FROM Customers
UNION All
  SELECT top(100) * 
  FROM CustomerEurope
UNION All
  SELECT top(100) * 
  FROM CustomerAsia
UNION All
  SELECT top(100) * 
  FROM CustomerAmericas

Moment.js stores dates it utc and can apply different timezones to it. By default it applies your local timezone. If you want to set time on utc date time you need to specify utc timezone.

Try the following code:

var m = moment().utcOffset(0);
m.set({hour:0,minute:0,second:0,millisecond:0})
m.toISOString()
m.format()

Content-Type: application/json is just the content header. The content header is just information about the type of returned data, ex::JSON,image(png,jpg,etc..),html.

Keep in mind, that JSON in JavaScript is an array or object. If you want to see all the data, use console.log instead of alert:

alert(response.text); // Will alert "[object Object]" string
console.log(response.text); // Will log all data objects

If you want to alert the original JSON content as a string, then add single quotation marks ('):

echo "'" . json_encode(array('text' => 'omrele')) . "'";
// alert(response.text) will alert {"text":"omrele"}

Do not use double quotes. It will confuse JavaScript, because JSON uses double quotes on each value and key:

echo '<script>var returndata=';
echo '"' . json_encode(array('text' => 'omrele')) . '"';
echo ';</script>';

// It will return the wrong JavaScript code:
<script>var returndata="{"text":"omrele"}";</script>

Expanding on eumiro's comment, normally tuple(l) will convert a list l into a tuple:

In [1]: l = [4,5,6]

In [2]: tuple
Out[2]: <type 'tuple'>

In [3]: tuple(l)
Out[3]: (4, 5, 6)

However, if you've redefined tuple to be a tuple rather than the type tuple:

In [4]: tuple = tuple(l)

In [5]: tuple
Out[5]: (4, 5, 6)

then you get a TypeError since the tuple itself is not callable:

In [6]: tuple(l)
TypeError: 'tuple' object is not callable

You can recover the original definition for tuple by quitting and restarting your interpreter, or (thanks to @glglgl):

In [6]: del tuple

In [7]: tuple
Out[7]: <type 'tuple'>

Download Twisted and look at the source code. They employ some pretty advanced techniques.

There is a better way than having to manually navigate to https://url , knowing what button to click in what browser, knowing where and how to save the "certificate" file and finally knowing the magic incantation for the keytool to install it locally.

Just do this:

1. Save code below to InstallCert.java
2. Open command line and execute: javac InstallCert.java
3. Run like: java InstallCert <host>[:port] [passphrase] (port and passphrase are optional)

Here is the code for InstallCert, note the year in header, will need to modify some parts for "later" versions of java:

Look carefully how many brackets does your array have. I met an example when function returned answer with extra bracket, like that:

>>>approx
array([[[1192,  391]],
       [[1191,  409]],
       [[1209,  438]],
       [[1191,  409]]])

And this didn't work

>>> approx[1,1]
IndexError: index 1 is out of bounds for axis 1 with size 1

This could open the brackets:

>>> approx[:,0]
array([[1192,  391],
       [1191,  409],
       [1209,  438],
       [1191,  409]])

Now it is possible to use an ordinary element access notation:

>>> approx[:,0][1,1]
409

You can programmatically import data from a csv file in your Drive into an existing Google Sheet using Google Apps Script, replacing/appending data as needed.

Below is some sample code. It assumes that: a) you have a designated folder in your Drive where the CSV file is saved/uploaded to; b) the CSV file is named "report.csv" and the data in it comma-delimited; and c) the CSV data is imported into a designated spreadsheet. See comments in code for further details.

function importData() {
  var fSource = DriveApp.getFolderById(reports_folder_id); // reports_folder_id = id of folder where csv reports are saved
  var fi = fSource.getFilesByName('report.csv'); // latest report file
  var ss = SpreadsheetApp.openById(data_sheet_id); // data_sheet_id = id of spreadsheet that holds the data to be updated with new report data

  if ( fi.hasNext() ) { // proceed if "report.csv" file exists in the reports folder
    var file = fi.next();
    var csv = file.getBlob().getDataAsString();
    var csvData = CSVToArray(csv); // see below for CSVToArray function
    var newsheet = ss.insertSheet('NEWDATA'); // create a 'NEWDATA' sheet to store imported data
    // loop through csv data array and insert (append) as rows into 'NEWDATA' sheet
    for ( var i=0, lenCsv=csvData.length; i<lenCsv; i++ ) {
      newsheet.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
    }
    /*
    ** report data is now in 'NEWDATA' sheet in the spreadsheet - process it as needed,
    ** then delete 'NEWDATA' sheet using ss.deleteSheet(newsheet)
    */
    // rename the report.csv file so it is not processed on next scheduled run
    file.setName("report-"+(new Date().toString())+".csv");
  }
};


// http://www.bennadel.com/blog/1504-Ask-Ben-Parsing-CSV-Strings-With-Javascript-Exec-Regular-Expression-Command.htm
// This will parse a delimited string into an array of
// arrays. The default delimiter is the comma, but this
// can be overriden in the second argument.

function CSVToArray( strData, strDelimiter ) {
  // Check to see if the delimiter is defined. If not,
  // then default to COMMA.
  strDelimiter = (strDelimiter || ",");

  // Create a regular expression to parse the CSV values.
  var objPattern = new RegExp(
    (
      // Delimiters.
      "(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +

      // Quoted fields.
      "(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +

      // Standard fields.
      "([^\"\\" + strDelimiter + "\\r\\n]*))"
    ),
    "gi"
  );

  // Create an array to hold our data. Give the array
  // a default empty first row.
  var arrData = [[]];

  // Create an array to hold our individual pattern
  // matching groups.
  var arrMatches = null;

  // Keep looping over the regular expression matches
  // until we can no longer find a match.
  while (arrMatches = objPattern.exec( strData )){

    // Get the delimiter that was found.
    var strMatchedDelimiter = arrMatches[ 1 ];

    // Check to see if the given delimiter has a length
    // (is not the start of string) and if it matches
    // field delimiter. If id does not, then we know
    // that this delimiter is a row delimiter.
    if (
      strMatchedDelimiter.length &&
      (strMatchedDelimiter != strDelimiter)
    ){

      // Since we have reached a new row of data,
      // add an empty row to our data array.
      arrData.push( [] );

    }

    // Now that we have our delimiter out of the way,
    // let's check to see which kind of value we
    // captured (quoted or unquoted).
    if (arrMatches[ 2 ]){

      // We found a quoted value. When we capture
      // this value, unescape any double quotes.
      var strMatchedValue = arrMatches[ 2 ].replace(
        new RegExp( "\"\"", "g" ),
        "\""
      );

    } else {

      // We found a non-quoted value.
      var strMatchedValue = arrMatches[ 3 ];

    }

    // Now that we have our value string, let's add
    // it to the data array.
    arrData[ arrData.length - 1 ].push( strMatchedValue );
  }

  // Return the parsed data.
  return( arrData );
};

You can then create time-driven trigger in your script project to run importData() function on a regular basis (e.g. every night at 1AM), so all you have to do is put new report.csv file into the designated Drive folder, and it will be automatically processed on next scheduled run.

If you absolutely MUST work with Excel files instead of CSV, then you can use this code below. For it to work you must enable Drive API in Advanced Google Services in your script and in Developers Console (see How to Enable Advanced Services for details).

if you want to modify or update NSDictionary then first of all typecast it as NSMutableDictionary

let newdictionary = NSDictionary as NSMutableDictionary

then simply use

 newdictionary.setValue(value: AnyObject?, forKey: String)

You can use Comparator.reverseOrder() to have a comparator giving the reverse of the natural ordering.

If you want to reverse the ordering of an existing comparator, you can use Comparator.reversed().

Sample code:

Stream.of(1, 4, 2, 5)
    .sorted(Comparator.reverseOrder()); 
    // stream is now [5, 4, 2, 1]

Stream.of("foo", "test", "a")
    .sorted(Comparator.comparingInt(String::length).reversed()); 
    // stream is now [test, foo, a], sorted by descending length

A different take on this question, which might help someone:

I came here because I was debugging in Visual Studio on Windows, and I got confused about all this / vs \\ discussion (it really should not matter in most cases).

For me, the problem was: the "current directory" was not set to what I wanted in Visual Studio. It defaults to the directory of the executable (depending on how you set up your project).

Change it via: Right-click the solution -> Properties -> Working Directory

I only mention it because the question seems Windows-centric, which generally also means VisualStudio-centric, which tells me this hint might be relevant (:

The below method worked for me, Kudos to github user : midnightcodr

Make sure You remove any nodejs/npm packages already installed.

sudo apt-get purge nodejs

sudo apt-get purge npm

Now Install Node js using the command below( Thanks to midnightcodr on github)

curl -L https://raw.github.com/midnightcodr/rpi_node_install/master/setup.sh | bash -s 0.10.24

Note that you can invoke node with command node and not nodejs.

Once node is installed , Install npm

sudo apt-get install npm

For getting the list of ip addresses associated, you can use netstat command

netstat -rn 

This gives a long list of ip addresses and it is not easy to find the required field. The sample result is as following:

Routing tables
Internet:
Destination        Gateway            Flags        Refs      Use   Netif Expire
default            192.168.195.1      UGSc           17        0     en2
127                127.0.0.1          UCS             0        0     lo0
127.0.0.1          127.0.0.1          UH              1   254107     lo0
169.254            link#7             UCS             0        0     en2
192.168.195        link#7             UCS             3        0     en2
192.168.195.1      0:27:22:67:35:ee   UHLWIi         22      397     en2   1193
192.168.195.5      127.0.0.1          UHS             0        0     lo0

More result is truncated.......

The ip address of gateway is in the first line; one with default at its first column.

To display only the selected lines of result, we can use grep command along with netstat

netstat -rn | grep 'default'

This command filters and displays those lines of result having default. In this case, you can see result like following:

default            192.168.195.1      UGSc           14        0     en2

If you are interested in finding only the ip address of gateway and nothing else you can further filter the result using awk. The awk command matches pattern in the input result and displays the output. This can be useful when you are using your result directly in some program or batch job.

netstat -rn | grep 'default' | awk '{print $2}'

The awk command tells to match and print the second column of the result in the text. The final result thus looks like this:

192.168.195.1

In this case, netstat displays all result, grep only selects the line with 'default' in it, and awk further matches the pattern to display the second column in the text.

You can similarly use route -n get default command to get the required result. The full command is

route -n get default | grep 'gateway' | awk '{print $2}'

These commands work well in linux as well as unix systems and MAC OS.

Windows 7 has the arp command within it. arp -a should show you the static and dynamic type interfaces connected to your system.

A deadlock happens when a thread is waiting for something that never occurs.

Typically, it happens when a thread is waiting on a mutex or semaphore that was never released by the previous owner.

It also frequently happens when you have a situation involving two threads and two locks like this:

Thread 1               Thread 2

Lock1->Lock();         Lock2->Lock();
WaitForLock2();        WaitForLock1();   <-- Oops!

You generally detect them because things that you expect to happen never do, or the application hangs entirely.

All answers are awesome and explained everything very well

but I just want to point out different way for passing args to main method

in visual studio

1. right click on Project then choose Properties
2. go to Debug tab then on the Start Options section provide the app with your args

like this image

and happy knowing secrets

An educational example from the stat documentation:

import os, sys
from stat import *

def walktree(top, callback):
    '''recursively descend the directory tree rooted at top,
       calling the callback function for each regular file'''

    for f in os.listdir(top):
        pathname = os.path.join(top, f)
        mode = os.stat(pathname)[ST_MODE]
        if S_ISDIR(mode):
            # It's a directory, recurse into it
            walktree(pathname, callback)
        elif S_ISREG(mode):
            # It's a file, call the callback function
            callback(pathname)
        else:
            # Unknown file type, print a message
            print 'Skipping %s' % pathname

def visitfile(file):
    print 'visiting', file

if __name__ == '__main__':
    walktree(sys.argv[1], visitfile)

In my case, I just had to put the element one line down:

This throws an error:

export function DismissKeyboard(props: IProps) {
  return <TouchableWithoutFeedback
    onPress={() => Keyboard.dismiss()}> {props.children}
  </TouchableWithoutFeedback>;
}

While this does not throw an error:

export function DismissKeyboard(props: IProps) {
  return <TouchableWithoutFeedback
    onPress={() => Keyboard.dismiss()}>
    {props.children}
  </TouchableWithoutFeedback>;
}

SELECT *
    FROM (
                SELECT empno,
                       deptno, sal,
                       dense_rank( ) over ( order by sal desc) NRANK
                FROM emp
            )
    WHERE NRANK = 4

1) As Marc Gravell said, try to use ONE random-generator. It's always cool to add this to the constructor: System.Environment.TickCount.

2) One tip. Let's say you want to create 100 objects and suppose each of them should have its-own random-generator (handy if you calculate LOADS of random numbers in a very short period of time). If you would do this in a loop (generation of 100 objects), you could do this like that (to assure fully-randomness):

int inMyRandSeed;

for(int i=0;i<100;i++)
{
   inMyRandSeed = System.Environment.TickCount + i;
   .
   .
   .
   myNewObject = new MyNewObject(inMyRandSeed);  
   .
   .
   .
}

// Usage: Random m_rndGen = new Random(inMyRandSeed);

Cheers.

This topic is actually a little more complicated as described in the answers so far. This blogpost by Rob Norris explains it in more detail and gives examples on when using return will actually break your code (or at least have non-obvious effects).

At this point let me just quote the essence of the post. The most important statement is right in the beginning. Print this as a poster and put it to your wall :-)

The return keyword is not “optional” or “inferred”; it changes the meaning of your program, and you should never use it.

It gives one example, where it actually breaks something, when you inline a function

// Inline add and addR
def sum(ns: Int*): Int = ns.foldLeft(0)((n, m) => n + m) // inlined add

scala> sum(33, 42, 99)
res2: Int = 174 // alright

def sumR(ns: Int*): Int = ns.foldLeft(0)((n, m) => return n + m) // inlined addR

scala> sumR(33, 42, 99)
res3: Int = 33 // um.

because

A return expression, when evaluated, abandons the current computation and returns to the caller of the method in which return appears.

This is only one of the examples given in the linked post and it's the easiest to understand. There're more and I highly encourage you, to go there, read and understand.

When you come from imperative languages like Java, this might seem odd at first, but once you get used to this style it will make sense. Let me close with another quote:

If you find yourself in a situation where you think you want to return early, you need to re-think the way you have defined your computation.

Some cases where I have found it useful:

• mark a test that is incomplete, so it fails and warns you until you can finish it
• making sure an exception is thrown:

try{
  // do stuff...
  fail("Exception not thrown");
}catch(Exception e){
  assertTrue(e.hasSomeFlag());
}

Note:

Since JUnit4, there is a more elegant way to test that an exception is being thrown: Use the annotation @Test(expected=IndexOutOfBoundsException.class)

However, this won't work if you also want to inspect the exception, then you still need fail().

You are inside vim. To save changes and quit, type:

<esc> :wq <enter>

That means:

• Press Escape. This should make sure you are in command mode
• type in :wq
• Press Return

An alternative that stdcall in the comments mentions is:

• Press Escape
• Press shift+Z shift+Z (capital Z twice).

No, that's not really possible, as

• there can be more than one string giving the same MD5
• it was designed to be hard to "reverse"

The goal of the MD5 and its family of hashing functions is

• to get short "extracts" from long string
• to make it hard to guess where they come from
• to make it hard to find collisions, that is other words having the same hash (which is a very similar exigence as the second one)

Think that you can get the MD5 of any string, even very long. And the MD5 is only 16 bytes long (32 if you write it in hexa to store or distribute it more easily). If you could reverse them, you'd have a magical compacting scheme.

This being said, as there aren't so many short strings (passwords...) used in the world, you can test them from a dictionary (that's called "brute force attack") or even google for your MD5. If the word is common and wasn't salted, you have a reasonable chance to succeed...

To clarify for future reference, a2enmod, as is suggested in several answers above, is for Debian/Ubuntu. Red Hat does not use this to enable Apache modules - instead it uses LoadModule statements in httpd.conf.

Give each input a name attribute. Only the clicked input's name attribute will be sent to the server.

<input type="submit" name="publish" value="Publish">
<input type="submit" name="save" value="Save">

And then

<?php
    if (isset($_POST['publish'])) {
        # Publish-button was clicked
    }
    elseif (isset($_POST['save'])) {
        # Save-button was clicked
    }
?>

Edit: Changed value attributes to alt. Not sure this is the best approach for image buttons though, any particular reason you don't want to use input[type=image]?

Edit: Since this keeps getting upvotes I went ahead and changed the weird alt/value code to real submit inputs. I believe the original question asked for some sort of image buttons but there are so much better ways to achieve that nowadays instead of using input[type=image].

Make sure that you update your php.ini for CLI. For my case this was C:\wamp\bin\php\php5.4.3\php.ini and uncomment extension=php_openssl.dll line.

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

$sql="SELECT COUNT(*) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Your_Table_Name' AND COLUMN_NAME = 'Your_New_Column_Name'";
$RESULT = mysqli_query($conn,$sql);

The abobe query return 0 if the column is not present in your table then you need to run alter query like below

if($RESULT){
    $sqll="ALTER TABLE Your_table_Name ADD COLUMN Your_New_Column_Name varchar(20) NOT NULL DEFAULT 0";
}

Check if a program exists from a Bash script covers this very well. In any shell script, you're best off running command -v $command_name for testing if $command_name can be run. In bash you can use hash $command_name, which also hashes the result of any path lookup, or type -P $binary_name if you only want to see binaries (not functions etc.)

I would give the requests library a try for this. Essentially just a much easier to use wrapper around the standard library modules (i.e. urllib2, httplib2, etc.) you would use for the same thing. For example, to fetch json data from a url that requires basic authentication would look like this:

import requests

response = requests.get('http://thedataishere.com',
                         auth=('user', 'password'))
data = response.json()

For kerberos authentication the requests project has the reqests-kerberos library which provides a kerberos authentication class that you can use with requests:

import requests
from requests_kerberos import HTTPKerberosAuth

response = requests.get('http://thedataishere.com',
                         auth=HTTPKerberosAuth())
data = response.json()

There are two ways.

With attach

$ sudo docker attach 665b4a1e17b6 #by ID

With exec

$ sudo docker exec - -t 665b4a1e17b6 #by ID

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

If I understand the question, then it seems to me that the questioner is really asking "OK, so 3-tier is well understood, but it seems that there's a mix of hype, confusion, and uncertainty around what 4-tier, or to generalize, N-tier architectures mean. So...what's a definition of N-tier that is widely understood and agreed upon?"

It's actually a fairly deep question, and to explain why, I need to go a little deeper. Bear with me.

The classic 3-tier architecture: database, "business logic" and presentation, is a good way to clarify how to honor the principle of separation of concerns. Which is to say, if I want to change how "the business" wants to service customers, I should not have to look through the entire system to figure out how to do this, and in particular, decisions business issues shouldn't be scattered willy-nilly through the code.

Now, this model served well for decades, and it is the classic 'client-server' model. Fast forward to cloud offerings, where web browsers are the user interface for a broad and physically distributed set of users, and one typically ends up having to add content distribution services, which aren't a part of the classic 3-tier architecture (and which need to be managed in their own right).

The concept generalizes when it comes to services, micro-services, how data and computation are distributed and so on. Whether or not something is a 'tier' largely comes down to whether or not the tier provides an interface and deployment model to services that are behind (or beneath) the tier. So a content distribution network would be a tier, but an authentication service would not be.

Now, go and read other descriptions of examples of N-tier architectures with this concept in mind, and you will begin to understand the issue. Other perspectives include vendor-based approaches (e.g. NGINX), content-aware load balancers, data isolation and security services (e.g. IBM Datapower), all of which may or may not add value to a given architecture, deployment, and use cases.

Push down the whole button. I suggest this it is looking nice in button.

#button:active {
    position: relative;
    top: 1px;
}

if you only want to push text increase top-padding and decrease bottom padding. You can also use line-height.

My problem was that the MySQL server wasn't actually installed. I had run the MySQL Installer, but it didn't install the MySQL server.

I reran the installer, click "Add", and then added MySQL server to the list. Now it works fine.

$('#usersSearch').keyup(function() { // handle keyup event on search input field

    var key = e.which || e.keyCode;  // store browser agnostic keycode

    if(key == 13) 
        $(this).closest('form').submit(); // submit parent form
}

Personally I would tend to use the approach Darin Dimitrov showed in his solution. This frees you up to be able to use the data annotation approach with validation AND have separate data attributes on each ViewModel corresponding to the task at hand. To minimize the amount of work for copying between model and viewmodel you should look at AutoMapper or ValueInjecter. Both have their individual strong points, so check them both.

Another possible approach for you would be to derive your viewmodel or model from IValidatableObject. This gives you the option to implement a function Validate. In validate you can return either a List of ValidationResult elements or issue a yield return for each problem you detect in validation.

The ValidationResult consists of an error message and a list of strings with the fieldnames. The error messages will be shown at a location near the input field(s).

public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
  if( NumberField < 0 )
  {
    yield return new ValidationResult( 
        "Don't input a negative number", 
        new[] { "NumberField" } );
  }

  if( NumberField > 100 )
  {
    yield return new ValidationResult( 
        "Don't input a number > 100", 
        new[] { "NumberField" } );
  }

  yield break;
}

Use your jquery like this

$('.home').css({'background-image':'url(images/tabs3.png)'});

You can query the all_tab_columns view in the database.

SELECT  table_name, column_name, data_type, data_length FROM all_tab_columns where table_name = 'CUSTOMER'

This means that somewhere else in your code, you have something like:

sum = 0

Which shadows the builtin sum (which is callable) with an int (which isn't).

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

Since [^a-z0-9] character class contains all that is not alnum, it contains white characters too!

 text.replace(/[^a-z0-9]+/gi, " ");

In a regular expression, you can "capture" parts of the matched string with (brackets); in this case, you are capturing the (^|_) and ([a-z]) parts of the match. These are numbered starting at 1, so you have back-references 1 and 2. Match 0 is the whole matched string.

The /e modifier takes a replacement string, and substitutes backslash followed by a number (e.g. \1) with the appropriate back-reference - but because you're inside a string, you need to escape the backslash, so you get '\\1'. It then (effectively) runs eval to run the resulting string as though it was PHP code (which is why it's being deprecated, because it's easy to use eval in an insecure way).

The preg_replace_callback function instead takes a callback function and passes it an array containing the matched back-references. So where you would have written '\\1', you instead access element 1 of that parameter - e.g. if you have an anonymous function of the form function($matches) { ... }, the first back-reference is $matches[1] inside that function.

So a /e argument of

'do_stuff(\\1) . "and" . do_stuff(\\2)'

could become a callback of

function($m) { return do_stuff($m[1]) . "and" . do_stuff($m[2]); }

Or in your case

'strtoupper("\\2")'

could become

function($m) { return strtoupper($m[2]); }

Note that $m and $matches are not magic names, they're just the parameter name I gave when declaring my callback functions. Also, you don't have to pass an anonymous function, it could be a function name as a string, or something of the form array($object, $method), as with any callback in PHP, e.g.

function stuffy_callback($things) {
    return do_stuff($things[1]) . "and" . do_stuff($things[2]);
}
$foo = preg_replace_callback('/([a-z]+) and ([a-z]+)/', 'stuffy_callback', 'fish and chips');

As with any function, you can't access variables outside your callback (from the surrounding scope) by default. When using an anonymous function, you can use the use keyword to import the variables you need to access, as discussed in the PHP manual. e.g. if the old argument was

'do_stuff(\\1, $foo)'

then the new callback might look like

function($m) use ($foo) { return do_stuff($m[1], $foo); }

Gotchas

• Use of preg_replace_callback is instead of the /e modifier on the regex, so you need to remove that flag from your "pattern" argument. So a pattern like /blah(.*)blah/mei would become /blah(.*)blah/mi.
• The /e modifier used a variant of addslashes() internally on the arguments, so some replacements used stripslashes() to remove it; in most cases, you probably want to remove the call to stripslashes from your new callback.

StringUtils.abbreviate from Apache Commons Lang library could be your friend:

StringUtils.abbreviate("abcdefg", 6) = "abc..."
StringUtils.abbreviate("abcdefg", 7) = "abcdefg"
StringUtils.abbreviate("abcdefg", 8) = "abcdefg"
StringUtils.abbreviate("abcdefg", 4) = "a..."

Commons Lang3 even allow to set a custom String as replacement marker. With this you can for example set a single character ellipsis.

StringUtils.abbreviate("abcdefg", "\u2026", 6) = "abcde…"

I don't know the logging module very well, but I'm using it in the way that I usually want to disable only debug (or info) messages. You can use Handler.setLevel() to set the logging level to CRITICAL or higher.

Also, you could replace sys.stderr and sys.stdout by a file open for writing. See http://docs.python.org/library/sys.html#sys.stdout. But I wouldn't recommend that.

Information provided by @Gord

As of September 2019 pywin32 is now available from PyPI and installs the latest version (currently version 224). This is done via the pip command

pip install pywin32

If you wish to get an older version the sourceforge link below would probably have the desired version, if not you can use the command, where xxx is the version you require, e.g. 224

pip install pywin32==xxx

This differs to the pip command below as that one uses pypiwin32 which currently installs an older (namely 223)

Browsing the docs I see no reason for these commands to work for all python3.x versions, I am unsure on python2.7 and below so you would have to try them and if they do not work then the solutions below will work.

Probably now undesirable solutions but certainly still valid as of September 2019

There is no version of specific version ofwin32api. You have to get the pywin32module which currently cannot be installed via pip. It is only available from this link at the moment.

https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/

The install does not take long and it pretty much all done for you. Just make sure to get the right version of it depending on your python version :)

EDIT

Since I posted my answer there are other alternatives to downloading the win32api module.

It is now available to download through pip using this command;

pip install pypiwin32

Also it can be installed from this GitHub repository as provided in comments by @Heath

It sounds like the populate method is what your looking for. First make small change to your post schema:

var postSchema = new Schema({
    name: String,
    postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Then make your model:

var Post = mongoose.model('Post', postSchema);

Then, when you make your query, you can populate references like this:

Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
    // do stuff with post
});

The clean, fast, and easy solutions posted as of the date of this answer are unsatisfactory. They are constructed over the flawed statement that SVG documents lack z order. Libraries are not necessary either. One line of code can perform most operations to manipulate the z order of objects or groups of objects that might be required in the development of an app that moves 2D objects around in an x-y-z space.

Z Order Definitely Exists in SVG Document Fragments

What is called an SVG document fragment is a tree of elements derived from the base node type SVGElement. The root node of an SVG document fragment is an SVGSVGElement, which corresponds to an HTML5 <svg> tag. The SVGGElement corresponds to the <g> tag and permits aggregating children.

Having a z-index attribute on the SVGElement as in CSS would defeat the SVG rendering model. Sections 3.3 and 3.4 of W3C SVG Recommendation v1.1 2nd Edition state that SVG document fragments (trees of offspring from an SVGSVGElement) are rendered using what is called a depth first search of the tree. That scheme is a z order in every sense of the term.

Z order is actually a computer vision shortcut to avoid the need for true 3D rendering with the complexities and computing demands of ray tracing. The linear equation for the implicit z-index of elements in an SVG document fragment.

z-index = z-index_of_svg_tag + depth_first_tree_index / tree_node_qty

This is important because if you want to move a circle that was below a square to above it, you simply insert the square before the circle. This can be done easily in JavaScript.

Supporting Methods

SVGElement instances have two methods that support simple and easy z order manipulation.

• parent.removeChild(child)
• parent.insertBefore(child, childRef)

The Correct Answer That Doesn't Create a Mess

Because the SVGGElement (<g> tag) can be removed and inserted just as easily as a SVGCircleElement or any other shape, image layers typical of Adobe products and other graphics tools can be implemented with ease using the SVGGElement. This JavaScript is essentially a Move Below command.

parent.insertBefore(parent.removeChild(gRobot), gDoorway)

If the layer of a robot drawn as children of SVGGElement gRobot was before the doorway drawn as children of SVGGElement gDoorway, the robot is now behind the doorway because the z order of the doorway is now one plus the z order of the robot.

A Move Above command is almost as easy.

parent.insertBefore(parent.removeChild(gRobot), gDoorway.nextSibling())

Just think a=a and b=b to remember this.

insert after = move above
insert before = move below

Leaving the DOM in a State Consistent With the View

The reason this answer is correct is because it is minimal and complete and, like the internals of Adobe products or other well designed graphics editors, leaves the internal representation in a state that is consistent with the view created by rendering.

Alternative But Limited Approach

Another approach commonly used is to use CSS z-index in conjunction with multiple SVG document fragments (SVG tags) with mostly transparent backgrounds in all but the bottom one. Again, this defeats the elegance of the SVG rendering model, making it difficult to move objects up or down in the z order.

NOTES:

1. (https://www.w3.org/TR/SVG/render.html v 1.1, 2nd Edition, 16 August 2011)

   3.3 Rendering Order Elements in an SVG document fragment have an implicit drawing order, with the first elements in the SVG document fragment getting "painted" first. Subsequent elements are painted on top of previously painted elements.

   3.4 How groups are rendered Grouping elements such as the ‘g’ element (see container elements) have the effect of producing a temporary separate canvas initialized to transparent black onto which child elements are painted. Upon the completion of the group, any filter effects specified for the group are applied to create a modified temporary canvas. The modified temporary canvas is composited into the background, taking into account any group-level masking and opacity settings on the group.

You can use this command,

jmeter -n -t /path to the script.jmx -l /path to save results with file name file.jtl

But if you really want to run a load test in a remote machine, you should be able to make it run eventhough you close the window. So we can use nohup to ignore the HUP (hangup) signal. So you can use this command as below.

nohup sh jmeter.sh -n -t /path to the script.jmx -l /path to save results with file name file.jtl &

The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.

Instead of removeClass and addClass, you can also do it like this:

$('.IsBestAnswer').toggleClass('IsBestAnswer bestanswer');

You can do that without an I/O redirection:

sed -i 's/$/\n/' filename

You can also use this command to append a newline to a list of files:

find dir -name filepattern | xargs sed -i 's/$/\n/' filename

For echo, some shells implement it as a shell builtin command. It might not accept the -e option. If you still want to use echo, try to find where the echo binary file is, using which echo. In most cases, it is located in /bin/echo, so you can use /bin/echo -e "\n" to echo a new line.

You need to change the directory permission so that web server process can change the directory.

• To change ownership of the directory, use chown:

  chown -R user-id:group-id /path/to/the/directory
  

• To see which user own the web server process (change httpd accordingly):

  ps aux | grep httpd | grep -v grep

Found out what was wrong. I never installed the setuptools for python, so it was missing some vital files, like the egg ones.

If you find yourself having my issue above, download this file and then in powershell or command prompt, navigate to ez_setup’s directory and execute the command and this will run the file for you:

$ [sudo] python ez_setup.py

If you still need to install pip at this point, run:

$ [sudo] easy_install pip

easy_install was part of the setuptools, and therefore wouldn't work for installing pip.

Then, pip will successfully install django with the command:

$ [sudo] pip install django

Below is the example of searching for a keyword in the whole list and remove that item:

public class Book
{
  public int BookId { get; set; }
  public DateTime CreatedDate { get; set; }
  public string Text { get; set; }
  public string Autor { get; set; }
  public string Source { get; set; }
}

If you want to remove a book that contains some keyword in the Text property, you can create a list of keywords and remove it from list of books:

List<Book> listToSearch = new List<Book>()
   {
        new Book(){
            BookId = 1,
            CreatedDate = new DateTime(2014, 5, 27),
            Text = " test voprivreda...",
            Autor = "abc",
            Source = "SSSS"

        },
        new Book(){
            BookId = 2,
            CreatedDate = new DateTime(2014, 5, 27),
            Text = "here you go...",
            Autor = "bcd",
            Source = "SSSS"


        }
    };

var blackList = new List<string>()
            {
                "test", "b"
            }; 

foreach (var itemtoremove in blackList)
    {
        listToSearch.RemoveAll(p => p.Source.ToLower().Contains(itemtoremove.ToLower()) || p.Source.ToLower().Contains(itemtoremove.ToLower()));
    }


return listToSearch.ToList();

One more thing, triggering GC Collect explicitly may NOT improve your program's performance. It is quite possible to make it worse.

The .NET GC is well designed and tuned to be adaptive, which means it can adjust GC0/1/2 threshold according to the "habit" of your program memory usage. So, it will be adapted to your program after some time running. Once you invoke GC.Collect explicitly, the thresholds will be reset! And the .NET has to spent time to adapt to your program's "habit" again.

My suggestion is always trust .NET GC. Any memory problem surfaces, check ".NET Memory" performance counter and diagnose my own code.

If the response code isn't 200 or 2xx, use getErrorStream() instead of getInputStream().

If you are considering using multidimensional arrays, then there is one additional difference between std::array and std::vector. A multidimensional std::array will have the elements packed in memory in all dimensions, just as a c style array is. A multidimensional std::vector will not be packed in all dimensions.

Given the following declarations:

int cConc[3][5];
std::array<std::array<int, 5>, 3> aConc;
int **ptrConc;      // initialized to [3][5] via new and destructed via delete
std::vector<std::vector<int>> vConc;    // initialized to [3][5]

A pointer to the first element in the c-style array (cConc) or the std::array (aConc) can be iterated through the entire array by adding 1 to each preceding element. They are tightly packed.

A pointer to the first element in the vector array (vConc) or the pointer array (ptrConc) can only be iterated through the first 5 (in this case) elements, and then there are 12 bytes (on my system) of overhead for the next vector.

This means that a std::vector> array initialized as a [3][1000] array will be much smaller in memory than one initialized as a [1000][3] array, and both will be larger in memory than a std:array allocated either way.

This also means that you can't simply pass a multidimensional vector (or pointer) array to, say, openGL without accounting for the memory overhead, but you can naively pass a multidimensional std::array to openGL and have it work out.

If you start having to mentally count off the parameters in the signature and match them to the call, then it is time to refactor!

If you are on a 64bit build of ubuntu or debian (see e.g. 'cat /proc/version') you should simply use the 64bit cross compilers, if you cloned

git clone https://github.com/raspberrypi/tools

then the 64bit tools are in

tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64

use that directory for the gcc-toolchain. A useful tutorial for compiling that I followed is available here Building and compiling Raspberry PI Kernel (use the -x64 path from above as ${CCPREFIX})

As I've always heard the terms used in a load-balancing scenario, they are interchangeable. Both mean that once a session is started, the same server serves all requests for that session.

beware when comparing numbers that are package versions, like checking if grep 2.20 is greater than version 2.6:

$ awk 'BEGIN { print (2.20 >= 2.6) ? "YES" : "NO" }'
NO

$ awk 'BEGIN { print (2.2 >= 2.6) ? "YES" : "NO" }'
NO

$ awk 'BEGIN { print (2.60 == 2.6) ? "YES" : "NO" }'
YES

I solved such problem with such shell/awk function:

# get version of GNU tool
toolversion() {
    local prog="$1" operator="$2" value="$3" version

    version=$($prog --version | awk '{print $NF; exit}')

    awk -vv1="$version" -vv2="$value" 'BEGIN {
        split(v1, a, /\./); split(v2, b, /\./);
        if (a[1] == b[1]) {
            exit (a[2] '$operator' b[2]) ? 0 : 1
        }
        else {
            exit (a[1] '$operator' b[1]) ? 0 : 1
        }
    }'
}

if toolversion grep '>=' 2.6; then
   # do something awesome
fi

After reading several answers, I decided to do it with a simple solution: Instead of a shortcut, I made a .bat with only one line to call the main .bat and it works like I wanted.

In Sharepoint Server 2010 they are stored here:

"c:\Program Files\Common Files\Microsoft Shared\web server extensions\14\LOGS"

To view them you can use ULS Viewer by Microsoft (unsupported). http://ulsviewer.codeplex.com/

I newer version of xampp you may use another method first open your httpd-xampp.conf file and find the string "phpmyadmin" using ctrl+F command (Windows). and then replace this code

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

with this

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

Don't Forget to Restart your Xampp.

The valid way is:

disabled="disabled"

Browsers also might accept disabled="" but I would recommend you the first approach.

Now this being said I would recommend you writing a custom HTML helper in order to encapsulate this disabling functionality into a reusable piece of code:

using System;
using System.Linq.Expressions;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using System.Web.Routing;

public static class HtmlExtensions
{
    public static IHtmlString MyTextBoxFor<TModel, TProperty>(
        this HtmlHelper<TModel> htmlHelper, 
        Expression<Func<TModel, TProperty>> expression, 
        object htmlAttributes, 
        bool disabled
    )
    {
        var attributes = new RouteValueDictionary(htmlAttributes);
        if (disabled)
        {
            attributes["disabled"] = "disabled";
        }
        return htmlHelper.TextBoxFor(expression, attributes);
    }
}

which you could use like this:

@Html.MyTextBoxFor(
    model => model.ExpireDate, 
    new { 
        style = "width: 70px;", 
        maxlength = "10", 
        id = "expire-date" 
    }, 
    Model.ExpireDate == null
)

and you could bring even more intelligence into this helper:

public static class HtmlExtensions
{
    public static IHtmlString MyTextBoxFor<TModel, TProperty>(
        this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression,
        object htmlAttributes
    )
    {
        var attributes = new RouteValueDictionary(htmlAttributes);
        var metaData = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        if (metaData.Model == null)
        {
            attributes["disabled"] = "disabled";
        }
        return htmlHelper.TextBoxFor(expression, attributes);
    }
}

so that now you no longer need to specify the disabled condition:

@Html.MyTextBoxFor(
    model => model.ExpireDate, 
    new { 
        style = "width: 70px;", 
        maxlength = "10", 
        id = "expire-date" 
    }
)

This is relatively new to C# which makes it easy for us to call the functions with respect to the null or non-null values in method chaining.

old way to achieve the same thing was:

var functionCaller = this.member;
if (functionCaller!= null)
    functionCaller.someFunction(var someParam);

and now it has been made much easier with just:

member?.someFunction(var someParam);

I strongly recommend this doc page.

It's looking for the file in the current directory.

First, go to that directory

cd /users/gcameron/Desktop/map

And then try to run it

python colorize_svg.py

Float the image right, which will at first cause your text to wrap around it.

Then whatever the very next element is, set it to { clear: right; } and everything will stop wrapping around the image.

I can also verify the above solution except I had to change in

**..\server\<server profile>\conf\props\jmx-console-users.properties**

You can use @input with ngOnChanges, to see the changes when it happened.

reference: https://angular.io/api/core/OnChanges

(or)

If you want to pass data between multiple component or routes then go with Rxjs way.

Service.ts

import { Injectable } from '@angular/core';
import { Observable, Subject } from 'rxjs';

@Injectable({ providedIn: 'root' })
export class MessageService {
  private subject = new Subject<any>();

  sendMessage(message: string) {
    this.subject.next({ text: message });
  }

  clearMessages() {
    this.subject.next();
  }

  getMessage(): Observable<any> {
    return this.subject.asObservable();
  }
}

Component.ts

import { Component, OnDestroy } from '@angular/core';
import { Subscription } from 'rxjs';

import { MessageService } from './_services/index';

@Component({
  selector: 'app',
  templateUrl: 'app.component.html'
})

export class AppComponent implements OnDestroy {
  messages: any[] = [];
  subscription: Subscription;

  constructor(private messageService: MessageService) {
    // subscribe to home component messages
    this.subscription = this.messageService.getMessage().subscribe(message => {
      if (message) {
        this.messages.push(message);
      } else {
        // clear messages when empty message received
        this.messages = [];
      }
    });
  }

  ngOnDestroy() {
    // unsubscribe to ensure no memory leaks
    this.subscription.unsubscribe();
  }
}

To expand upon the accepted answer by @Lucas:

Call this from your activity in one of the early life cycle events:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

Kotlin Example:

override fun onResume() {
  super.onResume()

  window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN)
}

I was looking for a ES6 example (so it could pass my linter) So for other people who are looking for the same:

$('#dSuggest').keyup((e) => {
    console.log(e.currentTarget.value);
});

I would also use keyup because you get the current value that is filled in.

Whatever code you are writing in viewDidLoad, Add that in viewWillappear(). This will solve your problem.

You can use VBSedit software to convert your VBS code to .exe file. You can download free version from Internet and installtion vbsedit applilcation on your system and convert the files to exe format.

Vbsedit is a good application for VBscripter's

You can use easy_date to make it easy:

import date_converter
my_date_string = date_converter.timestamp_to_string(1284101485, "%B %d, %Y")

y <- mean(x, na.rm=TRUE)

sd(y) for standard deviation var(y) for variance.

Both derivations use n-1 in the denominator so they are based on sample data.

The <img> element is empty — it doesn't have an end tag.

If the image is a background image, use CSS. If it is a content image, then set position: relative on a container, then absolutely position the image and/or text within it.

You could write a windows service that does nothing but execute your batch file. Since services run in their own desktop session, the command window won't be visible by the user.

Somehow Zacharias solution didn't work for me so I have used the below theme to resolve this issue...

<style name="DialogCustomTheme" parent="android:Theme.Holo.Dialog.NoActionBar">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
</style>

One can set this theme to dialog as below

final Dialog dialog = new Dialog(this, R.style.DialogCustomTheme); 

Enjoy!!

You can "compute the value for the specified byte array" using ComputeHash:

var hash = sha1.ComputeHash(temp);

If you want to analyse the result in string representation, then you will need to format the bytes using the {0:X2} format specifier.

Very often you have no option to setup the sending server so what I did I changed the XMLHttpRequest.open call in my javascript to a local get-file.php file where I have the following code in it:

<?php_x000D_
  $file = file($_GET['url']);_x000D_
  echo implode('', $file);_x000D_
?>

javascript is doing this:

var xhttp = new XMLHttpRequest();_x000D_
xhttp.onreadystatechange = function() {_x000D_
  if (this.readyState == 4 && this.status == 200) {_x000D_
    // File content is now in the this.responseText_x000D_
  }_x000D_
};_x000D_
xhttp.open("GET", "get-file.php?url=http://site/file", true);_x000D_
xhttp.send();

In my case this solved the restriction/situation just perfectly. No need to hack Firefox or servers. Just load your javascript/html file with that small php file into the server and you're done.

When using either a DISABLE or ENABLE TRIGGER statement in a batch that has other statements in it, the statement just before it must end with a semicolon. Otherwise, you'll get a syntax error. I tore my hair out with this one... And afterwards, I stumbled on this MS Connect item about the same thing. It is closed as won't fix.

see here

You can use the below:

SP_HELPDB [Master]
GO

There is a good way if you use validate() with parameters on a form and want to validate one field of your form manually afterwards:

var validationManager = $('.myForm').validate(myParameters);
...
validationManager.element($(this));

Documentation: Validator.element()

While sourceSets allows you to include entire directory structures, there's no way to exclude parts of it in Android Studio (as of version 1.2), as described here: Android Studio Exclude Class from build?

Until Android Studio gets updated to support include/exclude directives for Android sources, Symlinks work quite well. If you're using Windows, native tools such as junction or mklink can accomplish the equivalent of Un*x symlinks. CygWin can also create these with a little coersion. See: Git Symlinks in Windows and How to make symbolic link with cygwin in Windows 7

Just use in OOP manner a class like this:

class div
{
    public int remainder;

    public int quotient(int dividend, int divisor)
    {
        remainder = ...;
        return ...;
    }
}

The function member returns the quotient which most callers are primarily interested in. Additionally it stores the remainder as a data member, which is easily accessible by the caller afterwards.

This way you can have many additional "return values", very useful if you implement database or networking calls, where lots of error messages may be needed but only in case an error occurs.

I entered this solution also in the C++ question that OP is referring to.

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

This answer is detailed at sublime text forum:
http://www.sublimetext.com/forum/viewtopic.php?f=3&p=42052
This answer has links for choosing an appropriate font for your OS,
and gives an answer to an edge case of fonts not lining up.

Another website that lists great monospaced free fonts for programmers. http://hivelogic.com/articles/top-10-programming-fonts

On stackoverflow, see:

Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?

MattDMo's answer here: What is the default font of Sublime Text?

I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)

Other viewing environments that benefit from shorter lines: github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

managementObjects.Cast<ManagementBaseObject>().ToList(); is a good choice.

You could improve performance by pre-initialising the list capacity:

    public static class Helpers
    {
        public static List<T> CollectionToList<T>(this System.Collections.ICollection other)
        {
            var output = new List<T>(other.Count);

            output.AddRange(other.Cast<T>());

            return output;
        }
    }

This code worked for me, it kills all existing connections of a database. All you have to do is change the line Set @dbname = 'databaseName' so it has your database name.

Use Master
Go

Declare @dbname sysname

Set @dbname = 'databaseName'

Declare @spid int
Select @spid = min(spid) from master.dbo.sysprocesses
where dbid = db_id(@dbname)
While @spid Is Not Null
Begin
        Execute ('Kill ' + @spid)
        Select @spid = min(spid) from master.dbo.sysprocesses
        where dbid = db_id(@dbname) and spid > @spid
End

after this I was able to restore it

The regular UITableViewCell works well to position things but the cell.imageView doesn't seem to behave like you want it to. I found that it's simple enough to get the UITableViewCell to lay out properly by first giving the cell.imageView a properly sized image like

// Putting in a blank image to make sure text always pushed to the side.
UIGraphicsBeginImageContextWithOptions(CGSizeMake(kGroupImageDimension, kGroupImageDimension), NO, 0.0);
UIImage *blank = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
cell.imageView.image = blank;

Then you can just connect up your own properly working UIImageView with

// The cell.imageView increases in size to accomodate the image given it.
// We don't want this behaviour so we just attached a view on top of cell.imageView.
// This gives us the positioning of the cell.imageView without the sizing
// behaviour.
UIImageView *anImageView = nil;
NSArray *subviews = [cell.imageView subviews];
if ([subviews count] == 0)
{
    anImageView = [[UIImageView alloc] init];
    anImageView.translatesAutoresizingMaskIntoConstraints = NO;
    [cell.imageView addSubview:anImageView];

    NSLayoutConstraint *aConstraint = [NSLayoutConstraint constraintWithItem:anImageView attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:cell.imageView attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0];
    [cell.imageView addConstraint:aConstraint];

    aConstraint = [NSLayoutConstraint constraintWithItem:anImageView attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:cell.imageView attribute:NSLayoutAttributeCenterY multiplier:1.0 constant:0.0];
    [cell.imageView addConstraint:aConstraint];

    aConstraint = [NSLayoutConstraint constraintWithItem:anImageView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:0.0 constant:kGroupImageDimension];
    [cell.imageView addConstraint:aConstraint];

    aConstraint = [NSLayoutConstraint constraintWithItem:anImageView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:0.0 constant:kGroupImageDimension];
    [cell.imageView addConstraint:aConstraint];
}
else
{
    anImageView = [subviews firstObject];
}

Set the image on anImageView and it will do what you expect a UIImageView to do. Be the size you want it regardless of the image you give it. This should go in tableView:cellForRowAtIndexPath:

<?php

  $taxonomy     = 'product_cat';
  $orderby      = 'name';  
  $show_count   = 0;      // 1 for yes, 0 for no
  $pad_counts   = 0;      // 1 for yes, 0 for no
  $hierarchical = 1;      // 1 for yes, 0 for no  
  $title        = '';  
  $empty        = 0;

  $args = array(
         'taxonomy'     => $taxonomy,
         'orderby'      => $orderby,
         'show_count'   => $show_count,
         'pad_counts'   => $pad_counts,
         'hierarchical' => $hierarchical,
         'title_li'     => $title,
         'hide_empty'   => $empty
  );
 $all_categories = get_categories( $args );
 foreach ($all_categories as $cat) {
    if($cat->category_parent == 0) {
        $category_id = $cat->term_id;       
        echo '<br /><a href="'. get_term_link($cat->slug, 'product_cat') .'">'. $cat->name .'</a>';

        $args2 = array(
                'taxonomy'     => $taxonomy,
                'child_of'     => 0,
                'parent'       => $category_id,
                'orderby'      => $orderby,
                'show_count'   => $show_count,
                'pad_counts'   => $pad_counts,
                'hierarchical' => $hierarchical,
                'title_li'     => $title,
                'hide_empty'   => $empty
        );
        $sub_cats = get_categories( $args2 );
        if($sub_cats) {
            foreach($sub_cats as $sub_category) {
                echo  $sub_category->name ;
            }   
        }
    }       
}
?>

This will list all the top level categories and subcategories under them hierarchically. do not use the inner query if you just want to display the top level categories. Style it as you like.

The following code changes the hexadecimal string to a byte array by parsing the string byte-by-byte.

public static byte[] ConvertHexStringToByteArray(string hexString)
{
    if (hexString.Length % 2 != 0)
    {
        throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number of digits: {0}", hexString));
    }

    byte[] data = new byte[hexString.Length / 2];
    for (int index = 0; index < data.Length; index++)
    {
        string byteValue = hexString.Substring(index * 2, 2);
        data[index] = byte.Parse(byteValue, NumberStyles.HexNumber, CultureInfo.InvariantCulture);
    }

    return data; 
}

I have a more fleshed out example of using some of the work above in the context of a Gitea container, but it could easily be converted to another container based on the name. Also, you could probably use the docker ps --filter capability to set $GITEA_CONTAINER in a newer system or one without docker-compose in use.

# Set to name or ID of the container to be watched.
GITEA_CONTAINER=$(./bin/docker-compose ps |grep git|cut -f1 -d' ')

# Set timeout to the number of seconds you are willing to wait.
timeout=500; counter=0
# This first echo is important for keeping the output clean and not overwriting the previous line of output.
echo "Waiting for $GITEA_CONTAINER to be ready (${counter}/${timeout})"
#This says that until docker inspect reports the container is in a running state, keep looping.
until [[ $(docker inspect --format '{{json .State.Running}}' $GITEA_CONTAINER) == true ]]; do

  # If we've reached the timeout period, report that and exit to prevent running an infinite loop.
  if [[ $timeout -lt $counter ]]; then
    echo "ERROR: Timed out waiting for $GITEA_CONTAINER to come up."
    exit 1
  fi

  # Every 5 seconds update the status
  if (( $counter % 5 == 0 )); then
    echo -e "\e[1A\e[KWaiting for $GITEA_CONTAINER to be ready (${counter}/${timeout})"
  fi

  # Wait a second and increment the counter
  sleep 1s
  ((counter++))

done

This code works:

  let str = "governance[string_i_want]"; 
  let res = str.match(/[^governance\[](.*)[^\]]/g);

res will equal "string_i_want". However, in this example res is still an array, so do not treat res like a string.

By grouping the characters I do not want, using [^string], and matching on what is between the brackets, the code extracts the string I want!

You can try it out here: https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_match_regexp

Good luck.

It is possible.

When you use Return inside a procedure, the control is transferred to the calling program which calls the procedure. It is like an exit in loops.

It won't return any value.

If this is a Windows app, try checking for a duplicate in the Global Assembly Cache (GAC). Something is overriding your bin / debug version.

If this is a web app, you may need to delete on server and re-upload. If you are publishing you may want to check the Delete all existing files prior to publish check box. Depending on Visual Studio version it should be located in Publish > Settings > File Publish Options

I had approximately the same problem with Laravel 5.5 on ubuntu, finally i've found a solution here to switch between the versions of php used by apache :

1. sudo a2dismod php5
2. sudo a2enmod php7.1
3. sudo service apache2 restart

and it works

If you are only doing GET requests and you need another simple solution from within your Chrome browser, just install the "Open Multiple URLs" extension:

https://chrome.google.com/webstore/detail/open-multiple-urls/oifijhaokejakekmnjmphonojcfkpbbh?hl=en

I've just ran 1500 url's at once, did lag google a bit but it works.

I think this is the Easiest way to populate/model a table with ResultSet.. Download and include rs2xml.jar Get rs2xml.jar in your libraries..

import net.proteanit.sql.DbUtils;

    try
    {
    CreateConnection();
    PreparedStatement st =conn.prepareStatement("Select * from ABC;");
    ResultSet rs = st.executeQuery();
    tblToBeFilled.setModel(DbUtils.resultSetToTableModel(rs));
    conn.close();
    }
    catch(Exception ex)
    {
    JOptionPane.showMessageDialog(null, ex.toString());
    }

The following will match on any string that starts with mailto, ftp or http:

 RegEx reg = new RegEx("^(mailto|ftp|http)");

To break it down:

• ^ matches start of line
• (mailto|ftp|http) matches any of the items separated by a |

I would find StartsWith to be more readable in this case.
