Shift-tab doesn't seem to work on multi-lines in Aptana. It also doesn't work on single lines with a single preceding space. Any workarounds? I use shift-tab (outdent) to fix badly formatted code all the time.

I miss NetBeans ...

UPDATE: it works on multi-newlines, if the multi-lines have the same level of indentation. It should just continue outdenting the other lines that haven't reached the beginning of the new line yet. Is there an option to change this I wonder?

From the Project Explorer, expand the project you want to hook up to a remote site (or just right click and create a new Web project that's empty if you just want to explore a remote site from there). There's a "Connections" node, right click it and select "Add New connection...". A dialog will appear, at bottom you can select the destination as Remote and then click the "New..." button. There you can set up an FTP/FTPS/SFTP connection.

That's how you set up a connection that's tied to a project, typically for upload/download/sync between it and a project.

You can also do Window > Show View > Remote. From that view, you can click the globe icon in the upper right to add connections and in this view you can just browse your remote connections.

It seems having msysgit (Git for Windows) installed is causing the problem.

In most cases you'll have a pretty recent version of Git for Windows installed. Cited from https://code.google.com/p/tortoisegit/:

There was a security issue in Git, see here. Git for Windows < 1.9.5 is affected - so you should update, TortoiseGit itself is not affected (using the default configuration; only if libgit2 is manually enabled for checkout/fetching). TortoiseGit 1.8.13.0 includes all fixes.

But it seems Aptana Studio Installer won't accept any pre-installed version of Git for Windows!

What you need to do:

1. Uninstall Git for Windows.
2. Install Aptana Studio.
   Apanta Studio 3.6.1 will install Git for Windows 1.8.4-preview20130916.
3. Download latest version of Git for Windows from http://msysgit.github.io/.
4. Install latest version of Git for Windows.
   The outdated Git for Windows 1.8.4-preview20130916 will be updated to recent version.

That's it !!!

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Maybe someone prefers

Install node.js then

npm install -g servez

usage

servez [options] [path]

With no path it serves the current folder.

By default it serves index.html for folder paths if it exists. It serves a directory listing for folders otherwise. It also serves CORS headers. You can optionally turn on basic authentication with --username=somename --password=somepass and you can serve https.

Well, to do this one can also use the freopen function provided in C++ - http://www.cplusplus.com/reference/cstdio/freopen/ and read the file line by line as follows -:

#include<cstdio>
#include<iostream>

using namespace std;

int main(){
   freopen("path to file", "rb", stdin);
   string line;
   while(getline(cin, line))
       cout << line << endl;
   return 0;
}

If you want to make sure the border is on the inside of your element, you can use

box-sizing:border-box;

this will place the following border on the inside of the element:

border: 10px solid black;

(similar result you'd get using the additonal parameter inset on box-shadow, but instead this one is for the real border and you can still use your shadow for something else.)

Note to another answer above: as soon as you use any inset on box-shadow of a certain element, you are limited to a maximum of 2 box-shadows on that element and would require a wrapper div for further shadowing.

Both solutions should as well get you rid of the undesired 3D effects. Also note both solutions are stackable (see the example I've added in 2018)

.example-border {_x000D_
  width:100px;_x000D_
  height:100px;_x000D_
  border:40px solid blue;_x000D_
  box-sizing:border-box;_x000D_
  float:left;_x000D_

The only way that worked for me, is by copying the dll into your desktop or something, add reference to it, then delete the dll from your desktop. Visual Studio will refresh itself, and will finally reference the dll from the GAC on itself.

For anyone doing this on iOS8, this is what I had to do:

I have a swift class file titled SettingsView.swift and a .xib file named SettingsView.xib. I run this in MasterViewController.swift (or any view controller really to open a second view controller)

@IBAction func openSettings(sender: AnyObject) {
        var mySettings: SettingsView = SettingsView(nibName: "SettingsView", bundle: nil) /<--- Notice this "nibName" 
        var modalStyle: UIModalTransitionStyle = UIModalTransitionStyle.CoverVertical
        mySettings.modalTransitionStyle = modalStyle
        self.presentViewController(mySettings, animated: true, completion: nil)

    }

String url = "https://www.murait.com/";
if (url.startsWith("https://") || url.startsWith("http://")) {
    Uri uri = Uri.parse(url);
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(intent);
}else{
    Toast.makeText(mContext, "Invalid Url", Toast.LENGTH_SHORT).show();
}

You have to check that the URL is valid or not. If URL is invalid application may crash so that you have to check URL is valid or not by this method.

If you know the name of the alias, you can use the --help option to describe it. For example:

$ git sa --help
`git sa' is aliased to `stash'

$ git a --help
`git a' is aliased to `add'

You can't do it with client side script only... you could make an AJAX call to some server side code that will send an email...

If you know the the name of the file and if you always want to download that specific file, then you can easily get the ID and other attributes for your desired file from: https://developers.google.com/drive/v2/reference/files/list (towards the bottom you will find a way to run queries). In the q field enter title = 'your_file_name' and run it. You should see some result show up right below and within it should be an "id" field. That is the id you are looking for.

You can also play around with additional parameters from: https://developers.google.com/drive/search-parameters

You could add your JSON file as an external using webpack config. Then you can load up that json in any of your react modules.

You can create a stored procedure passing 2 dates

CREATE PROCEDURE SELECTALLDATES
(
@StartDate as date,
@EndDate as date
)
AS
Declare @Current as date = DATEADD(DD, 1, @BeginDate);

Create table #tmpDates
(displayDate date)

WHILE @Current < @EndDate
BEGIN
insert into #tmpDates
VALUES(@Current);
set @Current = DATEADD(DD, 1, @Current) -- add 1 to current day
END

Select * 
from #tmpDates

drop table #tmpDates

I don't know if this is new functionality, but this will plot on separate figures:

df.plot(y='korisnika')
df.plot(y='osiguranika')

while this will plot on the same figure: (just like the code in the op)

df.plot(y=['korisnika','osiguranika'])

I found this question because I was using the former method and wanted them to plot on the same figure, so your question was actually my answer.

The CosisEntities class is your DbContext. When you create a context in a using block, you're defining the boundaries for your data-oriented operation.

In your code, you're trying to emit the result of a query from a method and then end the context within the method. The operation you pass the result to then tries to access the entities in order to populate the grid view. Somewhere in the process of binding to the grid, a lazy-loaded property is being accessed and Entity Framework is trying to perform a lookup to obtain the values. It fails, because the associated context has already ended.

You have two problems:

1. You're lazy-loading entities when you bind to the grid. This means that you're doing lots of separate query operations to SQL Server, which are going to slow everything down. You can fix this issue by either making the related properties eager-loaded by default, or asking Entity Framework to include them in the results of this query by using the Include extension method.

2. You're ending your context prematurely: a DbContext should be available throughout the unit of work being performed, only disposing it when you're done with the work at hand. In the case of ASP.NET, a unit of work is typically the HTTP request being handled.

To answer a modulo x % y, you ask two questions:

A- How many times y goes in x without remainder ? For 2%4 that's 0.

B- How much do you need to add to get from that back to x ? To get from 0 back to 2 you'll need 2-0, i.e. 2.

These can be summed up in one question like so: How much will you need to add to the integer-ish result of the division of x by y, to get back at x?

By integer-ish it is meant only whole numbers and not fractions whatsoever are of interest.

A fractional division remainder (e.g. .283849) is not of interest in modulo because modulo only deals with integer numbers.

You can use this module which is easy to use: https://github.com/halilb/react-native-textinput-effects

For future reference, you can get help for any command by using the /? switch, which should explain what switches do what.

According to the set /? screen, the format for set /p is SET /P variable=[promptString] which would indicate that the p in /p is "prompt." It just prints in your example because <nul passes in a nul character which immediately ends the prompt so it just acts like it's printing. It's still technically prompting for input, it's just immediately receiving it.

/L in for /L generates a List of numbers.

From ping /?:

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.

    -f             Set Don't Fragment flag in packet (IPv4-only).
    -i TTL         Time To Live.
    -v TOS         Type Of Service (IPv4-only. This setting has been deprecated

    -R             Use routing header to test reverse route also (IPv6-only).
    -S srcaddr     Source address to use.
    -4             Force using IPv4.
    -6             Force using IPv6.

You can use angular's function called angular.isUndefined(value) returns boolean.

You may read more about angular's functions here: AngularJS Functions (isUndefined)

It should be

In C, simple quotes delimit a single character whereas double quotes are for strings.

Using this code you can copy any class object to another class object for same name and same type of properties.

JavaScriptSerializer JsonConvert = new JavaScriptSerializer(); 
string serializeString = JsonConvert.Serialize(objectEntity);
objectViewModel objVM = JsonConvert.Deserialize<objectViewModel>(serializeString);

Try to set response dataType property directly:

dataType: 'text'

and put

die(''); 

in the end of your php file. You've got error callback cause jquery cannot parse your response. In anyway, you may use a "complete:" callback, just to make sure your request has been processed.

Try this:

  <video width="320" height="240"  autoplay muted>
            <source src="video.mp4" type="video/mp4">

Another possibility with Guava:

dependency: compile 'com.google.guava:guava:11.0.2'

import com.google.common.io.ByteStreams;
...

String total = new String(ByteStreams.toByteArray(inputStream ));

all: program1 program2

program1:
    gcc -Wall -o prog1 program1.c

program2:
    gcc -Wall -o prog2 program2.c

Increasing number of max-connections will not solve the problem.

We were experiencing the same situation on our servers. This is what happens

User open a page/view, that connect to the database, query the database, still query(queries) were not finished and user leave the page or move to some other page. So the connection that was open, will remains open, and keep increasing number of connections, if there are more users connecting with the db and doing something similar.

You can set interactive_timeout MySQL, bydefault it is 28800 (8hours) to 1 hour

SET interactive_timeout=3600

For whoever is using Kotlin, honestly the by far easiest way to iterate over a SparseArray is: Use the Kotlin extension from Anko or Android KTX! (credit to Yazazzello for pointing out Android KTX)

Simply call forEach { i, item -> }

body{
height: 100%;
overflow: hidden !important;
width: 100%;
position: fixed;

Use this code to setup your mongodb connection:

var mongoose = require('mongoose');

var mongoURI = "mongodb://localhost:27017/test";
var MongoDB = mongoose.connect(mongoURI).connection;
MongoDB.on('error', function(err) { console.log(err.message); });
MongoDB.once('open', function() {
  console.log("mongodb connection open");
});

Make sure mongod is running while you start the server. Are you using Express or just a simple node.js server? What is the error message you get with the above code?

Try this:

SELECT table_name 
FROM information_schema.tables 
WHERE table_schema='public' AND table_type='BASE TABLE'

this one works!

You could simply use Runtime.exec()

I don't think WPF supports what you are trying to achieve i.e. assigning method to a button using method's name or btn1.Click = "btn1_Click". You will have to use approach suggested in above answers i.e. register button click event with appropriate method btn1.Click += btn1_Click;

UPDATE only changes the values you specify:

UPDATE table SET cell='new_value' WHERE whatever='somevalue'

For just elements this can be used to find the index of an element amongst it's sibling elements:

function getElIndex(el) {
    for (var i = 0; el = el.previousElementSibling; i++);
    return i;
}

Note that previousElementSibling isn't supported in IE<9.

Use following hexadecimal code for transparent text colour: #00FFFF00

Random random = new Random();
int n = random.nextInt(69) + 32;
if (n > 96) {
    n += 26;
}
char c = (char) n;

I guess it depends which punctuation you want to include, but this should generate a random character including all of the punctuation on this ASCII table. Basically, I've generated a random int from 32 - 96 or 123 - 126, which I have then casted to a char, which gives the ASCII equivalent of that number. Also, make sure youimport java.util.Random

Following is the simple function to encode xml escape chars in JS

Encoder.htmlEncode(unsafeText);

I use the following method in my JavaFX applications.

newWindowButton.setOnMouseClicked((event) -> {
    try {
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
        /* 
         * if "fx:controller" is not set in fxml
         * fxmlLoader.setController(NewWindowController);
         */
        Scene scene = new Scene(fxmlLoader.load(), 600, 400);
        Stage stage = new Stage();
        stage.setTitle("New Window");
        stage.setScene(scene);
        stage.show();
    } catch (IOException e) {
        Logger logger = Logger.getLogger(getClass().getName());
        logger.log(Level.SEVERE, "Failed to create new Window.", e);
    }
});

tl;dr

Data structures (DS) are important because they are used to perform operations on data which basically implies: take some input, process it, and give back the output.

Some data structures are more useful than others in some particular cases. Therefore, it is quite unfair to ask which (DS) is more efficient/speedy. It is like asking which tool is more efficient between a knife and fork. I mean all depends on the situation.

Lists

A list is mutable sequence, typically used to store collections of homogeneous items.

Sets

A set object is an unordered collection of distinct hashable objects. It is commonly used to test membership, remove duplicates from a sequence, and compute mathematical operations such as intersection, union, difference, and symmetric difference.

Usage

From some of the answers, it is clear that a list is quite faster than a set when iterating over the values. On the other hand, a set is faster than a list when checking if an item is contained within it. Therefore, the only thing you can say is that a list is better than a set for some particular operations and vice-versa.

I took the liberty to expand the answer from nona-urbiz; just add this to your ~/.bashrc:

git-pullall () { for RMT in $(git remote); do git pull -v $RMT $1; done; }    
alias git-pullall=git-pullall

git-pushall () { for RMT in $(git remote); do git push -v $RMT $1; done; }
alias git-pushall=git-pushall

Usage:

git-pullall master

git-pushall master ## or
git-pushall

If you do not provide any branch argument for git-pullall then the pull from non-default remotes will fail; left this behavior as it is, since it's analogous to git.

Making this case insensitive wasn't working in asp.net so I just specified each of the letters.

Here's what I had to do to get it working in an asp.net RegularExpressionValidator:

[Hh][Tt][Tt][Pp][Ss]?://(.*)

Notes:

• (?i) and using /whatever/i didn't work probably because javascript hasn't brought in all case sensitive functionality
• Originally had ^ at beginning but it didn't matter, but the (.*) did (Expression didn't work without (.*) but did work without ^)
• Didn't need to escape the // though might be a good idea.

Here's the full RegularExpressionValidator if you need it:

<asp:RegularExpressionValidator ID="revURLHeaderEdit" runat="server" 
    ControlToValidate="txtURLHeaderEdit" 
    ValidationExpression="[Hh][Tt][Tt][Pp][Ss]?://(.*)"
    ErrorMessage="URL should begin with http:// or https://" >
</asp:RegularExpressionValidator>

If you want to do your part as developer, utilizing open source libraries, you should try including all those open source licenses within your apk. To do this, you can use the merge method in your packagingOptions.

Example:

packagingOptions {
        // This will get include every license and notice regardless of what dir it’s in.
        merge '**/LICENSE.txt'
        merge '**/NOTICE.txt'
        merge '**/notice.txt'
        merge '**/license.txt'
        merge '**/NOTICE'
        merge '**/LICENSE'
        merge '**/notice'
        merge '**/license'
        merge '**/LGPL2.1'
        // This will exclude any README files, regardless of the dir or the file type.
        exclude '**/README.*'
}

This answer is better than using pickFirst because that method only picks the first license it finds and disregards all the rest, kinda rendering it useless in this case.

So in short, use the merge method to include all those licenses from those kickass open source libraries you’ve been using.

Make sure you evaluate the DataNucleus implementation of JDO. We started out with Hibernate because it appeared to be so popular but pretty soon realized that it's not a 100% transparent persistence solution. There are too many caveats and the documentation is full of 'if you have this situation then you must write your code like this' that took away the fun of freely modeling and coding however we want. JDO has never caused me to adjust my code or my model to get it to 'work properly'. I can just design and code simple POJOs as if I was going to use them 'in memory' only, yet I can persist them transparently.

The other advantage of JDO/DataNucleus over hibernate is that it doesn't have all the run time reflection overhead and is more memory efficient because it uses build time byte code enhancement (maybe add 1 sec to your build time for a large project) rather than hibernate's run time reflection powered proxy pattern.

Another thing you might find annoying with Hibernate is that a reference you have to what you think is the object... it's often a 'proxy' for the object. Without the benefit of byte code enhancement the proxy pattern is required to allow on demand loading (i.e. avoid pulling in your entire object graph when you pull in a top level object). Be prepared to override equals and hashcode because the object you think you're referencing is often just a proxy for that object.

Here's an example of frustrations you'll get with Hibernate that you won't get with JDO:

http://blog.andrewbeacock.com/2008/08/how-to-implement-hibernate-safe-equals.html
http://burtbeckwith.com/blog/?p=53

If you like coding to 'workarounds' then, sure, Hibernate is for you. If you appreciate clean, pure, object oriented, model driven development where you spend all your time on modeling, design and coding and none of it on ugly workarounds then spend a few hours evaluating JDO/DataNucleus. The hours invested will be repaid a thousand fold.

Update Feb 2017

For quite some time now DataNucleus' implements the JPA persistence standard in addition to the JDO persistence standard so porting existing JPA projects from Hibernate to DataNucleus should be very straight forward and you can get all of the above mentioned benefits of DataNucleus with very little code change, if any. So in terms of the question, the choice of a particular standard, JPA (RDBMS only) vs JDO (RDBMS + No SQL + ODBMSes + others), DataNucleus supports both, Hibernate is restricted to JPA only.

Performance of Hibernate DB updates

Another issue to consider when choosing an ORM is the efficiency of its dirty checking mechanism - that becomes very important when it needs to construct the SQL to update the objects that have changed in the current transaction - especially when there are a lot of objects. There is a detailed technical description of Hibernate's dirty checking mechanism in this SO answer: JPA with HIBERNATE insert very slow

Give your two buttons the same name and different values:

<input type="submit" name="submit_button" value="Do Something">
<input type="submit" name="submit_button" value="Do Something Else">

Then in your Flask view function you can tell which button was used to submit the form:

def contact():
    if request.method == 'POST':
        if request.form['submit_button'] == 'Do Something':
            pass # do something
        elif request.form['submit_button'] == 'Do Something Else':
            pass # do something else
        else:
            pass # unknown
    elif request.method == 'GET':
        return render_template('contact.html', form=form)

I do not know C#, but with a little guesswork I think I understand what

foo : int {
    get { return getFoo(); }
    set { setFoo(newValue); }
}

does. It looks very similar to what you have in Swift, but it's not the same: in Swift you do not have the getFoo and setFoo. That is not a little difference: it means you do not have any underlying storage for your value.

Swift has stored and computed properties.

A computed property has get and may have set (if it's writable). But the code in the getter and setter, if they need to actually store some data, must do it in other properties. There is no backing storage.

A stored property, on the other hand, does have backing storage. But it does not have get and set. Instead it has willSet and didSet which you can use to observe variable changes and, eventually, trigger side effects and/or modify the stored value. You do not have willSet and didSet for computed properties, and you do not need them because for computed properties you can use the code in set to control changes.

Sorry, but all the answers are difficult to understand for me as a beginner in graphics...

After some fiddling, this is working for me and it is easy to reason about.

@Override
public void draw(Graphics2D g) {
    AffineTransform tr = new AffineTransform();
    // X and Y are the coordinates of the image
    tr.translate((int)getX(), (int)getY());
    tr.rotate(
            Math.toRadians(this.rotationAngle),
            img.getWidth() / 2,
            img.getHeight() / 2
    );

    // img is a BufferedImage instance
    g.drawImage(img, tr, null);
}

I suppose that if you want to rotate a rectangular image this method wont work and will cut the image, but I thing you should create square png images and rotate that.

i use Mac and i deleted ADT bundle source. faced the same error so i went to project > clean and adb ran normally.

I came across this issue as well and originally thought it was a CocoaPods issue, but it was an issue in the apps build settings where someone (probably me) had set ${PODS_ROOT} in Header Search Paths and set it to be a recursive search. This was allowing it to find headers that were not intended to be used when building the app. Once I set this to use non-recursive everything was fine. using recursive search is a terrible hack to try to find the proper headers. Lesson learned.

You could try either of these. They are not giving me errors.

It is also the suggested method from typescript for array declaration.

By using the Array<Thing> it is making use of the generics in typescript. It is similar to asking for a List<T> in c# code.

// Declare with default value
private _possessions: Array<Thing> = new Array<Thing>();
// or
private _possessions: Array<Thing> = [];
// or -> prefered by ts-lint
private _possessions: Thing[] = [];

or

// declare
private _possessions: Array<Thing>;
// or -> preferd by ts-lint
private _possessions: Thing[];

constructor(){
    //assign
    this._possessions = new Array<Thing>();
    //or
    this._possessions = [];
}

I also faced this issue and after debugging the culprit was found. In my case it was the "space" character right before the https

I've used the open source control at http://dropdowncheckboxes.codeplex.com/ and been very happy with it. My addition was to allow a list of checked files to use just file names instead of full paths if the 'selected' caption gets too long. My addition is called instead of UpdateSelection in your postback handler:

// Update the caption assuming that the items are files<br/> 
// If the caption is too long, eliminate paths from file names<br/> 
public void UpdateSelectionFiles(int maxChars) {
  StringBuilder full = new StringBuilder(); 
  StringBuilder shorter = new StringBuilder();
  foreach (ListItem item in Items) { 
    if (item.Selected) { 
      full.AppendFormat("{0}; ", item.Text);
      shorter.AppendFormat("{0}; ", new FileInfo(item.Text).Name);
    } 
  } 
  if (full.Length == 0) Texts.SelectBoxCaption = "Select...";
  else if (full.Length <= maxChars) Texts.SelectBoxCaption = full.ToString(); 
  else Texts.SelectBoxCaption = shorter.ToString();
} 

If you want to execute multiple commands in a for loop, you can save the result of find with mapfile (bash >= 4) as an variable and go through the array with ${dirlist[@]}. It also works with directories containing spaces.

The find command is based on the answer by Boldewyn. Further information about the find command can be found there.

IFS=""
mapfile -t dirlist < <( find . -maxdepth 1 -mindepth 1 -type d -printf '%f\n' )
for dir in ${dirlist[@]}; do
    echo ">${dir}<"
    # more commands can go here ...
done

I had the same problem. Files defined in .gitingore where listed as untracked files when running git status.

The reason was that the .gitignore file was saved in UTF-16LE encoding, and not in UTF8 encoding.

After changing the encoding of the .gitignore file to UTF8 it worked for me.

It seemed that a lot of dependencies were incorrect.

Download the whole POM here

A good place to look for the correct dependencies is the Maven Repository website.

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

1. On Windows 8 Start Menu select All Apps
2. Right click on Visual Studio 2010 Icon
3. Select Open File Location
4. Right click on Visual Studio 2010 shortcut icon
5. Click Advanced button
6. Check the Run as Administrator checkbox
7. Click OK

If anyone is using WordPress, you can use something like:

if (jQuery('.dropdown-menu li').hasClass('active')) {
    jQuery('.current-menu-parent').addClass('current-menu-item');
}

The syntax is wrong in this clause (and similar ones)

    CASE lkey WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

It's either

    CASE WHEN [condition] THEN [expression] ELSE [expression] END

or

    CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END

So in your case it would read:

    CASE WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

Check out the documentation (The CASE expression):

You can change the default location of .m2 directory in m2.conf file. It resides in your maven installation directory.

add modify this line in

m2.conf

set maven.home C:\Users\me\.m2

Use the command as

java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>

The above command will set the mentioned paths to classpath only once for executing the class named TestClass.

If you want to execute more then one classes, then you can follow this

set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"

After this you can execute as many classes as you want just by simply typing

java <your-class-name>

The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)

If you want to set the classpth only once so that it could work for everytime, then do as follows

1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
    a.  Variable Name-     classpath
    b.  Variable Value-    .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.

Remember this will work every time. You don't need to explicitly set the classpath again and again.

NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.

Hope this will help you.

Try Date.now().

The skipping is most likely due to garbage collection. Typically garbage collection can be avoided by reusing variables as much as possible, but I can't say specifically what methods you can use to reduce garbage collection pauses.

There are two methods by which you can round up your double value.

1. Math.ceil
2. Math.floor

If you want your answer 4.90625 as 4 then you should use Math.floor and if you want your answer 4.90625 as 5 then you can use Math.ceil

You can refer following code for that.

public class TestClass {

    public static void main(String[] args) {
        int floorValue = (int) Math.floor((double)157 / 32);
        int ceilValue = (int) Math.ceil((double)157 / 32);
        System.out.println("Floor: "+floorValue);
        System.out.println("Ceil: "+ceilValue);

    }

}

You can use JsonBuilder for that.

Example Code:

import groovy.json.JsonBuilder

class Person {
    String name
    String address
}

def o = new Person( name: 'John Doe', address: 'Texas' )

println new JsonBuilder( o ).toPrettyString()

Use your jquery like this

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

The TextBoxFor is a newer MVC input extension introduced in MVC2.

The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.

See this page.

Use the return keyword to exit from a method.

public void someMethod() {
    //... a bunch of code ...
    if (someCondition()) {
        return;
    }
    //... otherwise do the following...
}

From the Java Tutorial that I linked to above:

Any method declared void doesn't return a value. It does not need to contain a return statement, but it may do so. In such a case, a return statement can be used to branch out of a control flow block and exit the method and is simply used like this:

return;

I had issues like this especially when debugging actively through my phone; at times it took 27 minutes. I did the following things and take note of the explanation under each - one may work for you:

1. Changed my gradle.properties file (under Gradle scripts if you have the project file view under Android option OR inside your project folder). I added this because my computer has some memory to spare - you can assign different values at the end depending on your computer specifications and android studio minimum requirements (Xmx8000m -XX:MaxPermSize=5000m) :

org.gradle.daemon=true

org.gradle.configureondemand=true

org.gradle.parallel=true

android.enableBuildCache=true

org.gradle.caching=true

org.gradle.jvmargs=-Xmx8000m -XX:MaxPermSize=5000m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

2. This did not completely solve my issue in my case. Therefore I also did as others had suggested before - to make my builds process offline:

File -> Settings/Preferences -> Build, Execution, Deployment -> Gradle

Global Gradle Settings (at the bottom)

Mark the checkbox named: Offline Work.

3. This reduced time substantially but it was erratic; at times took longer. Therefore I made some changes on Instant Run:

File -> Settings/Preferences -> Build, Execution, Deployment -> Instant Run

Checked : Enable Instant Run to hot swap code...

Checked: restart activity on code changes ...

4. The move above was erratic also and therefore I sought to find out if the problem may be the processes/memory that ran directly on either my phone and computer. Here I freed up a little memory space in my phone and storage (which was at 98% utilized - down to 70%) and also on task manager (Windows), increased the priority of both Android Studio and Java.exe to High. Take this step cautiously; depends on your computer's memory.

5. After all this my build time while debugging actively on my phone at times went down to 1 ~ 2 minutes but at times spiked. I decided to do a hack which surprised me by taking it down to seconds best yet on the same project that gave me 22 - 27 minutes was 12 seconds!:

Connect phone for debugging then click RUN

After it starts, unplug the phone - the build should continue faster and raise an error at the end indicating this : Session 'app': Error Installing APKs

Reconnect back the phone and click on RUN again...

ALTERNATIVELY

If the script/function/method I'm debugging is purely JAVA, not JAVA-android e.g. testing an API with JSONArrays/JSONObjects, I test my java functions/methods on Netbeans which can compile a single file and show the output faster then make necessary changes on my Android Studio files. This also saves me a lot of time.

EDIT

I tried creating a new android project in local storage and copied all my files from the previous project into the new one - java, res, manifest, gradle app and gradle project (with latest gradle classpath dependency). And now I can build on my phone in less than 15 seconds.

You cannot access elements of an empty vector by subscript.
Always check that the vector is not empty & the index is valid while using the [] operator on std::vector.
[] does not add elements if none exists, but it causes an Undefined Behavior if the index is invalid.

You should create a temporary object of your structure, fill it up and then add it to the vector, using vector::push_back()

subject subObj;
subObj.name = s1;
sub.push_back(subObj);

There might be a reason that Typescript is not installed globally, so install it

npm install -g typescript // installs typescript globally

If you want to convert .ts files into .js, do this as per your need

tsc file.ts // file.ts will be converted to file.js file
tsc         // all .ts files will be converted to .js files in the directory
tsc --watch // converts all .ts files to .js, and watch changes in .ts files

This is what I did:

yourEditText.setCursorVisible(false); //This code is used when you do not want the cursor to be visible at startup
        yourEditText.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                v.onTouchEvent(event);   // handle the event first
                InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                if (imm != null) {

                    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);  // hide the soft keyboard
                    yourEditText.setCursorVisible(true); //This is to display cursor when upon onTouch of Edittext
                }
                return true;
            }
        });

Here's an easy solution, from Wikibooks:

The placeins package provides the command \FloatBarrier, which can be used to prevent floats from being moved over it.

I just put \FloatBarrier before and after every table.

If anyone else was ever to maintain your code, they would almost certainly do a double take on version 2 -- that's extremely non-standard.

I would stick with version 1. I'm of the school of though that case statements without a statement block of their own should have an explicit // fall through comment next to them to indicate it is indeed your intent to fall through, thereby removing any ambiguity of whether you were going to handle the cases differently and forgot or something.

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

If a website's directory does NOT have an "index...." file, AND .htaccess has NOT been used to block access to the directory itself, then Apache will create an "index of" page for that directory. You can save that page, and its icons, using "Save page as..." along with the "Web page, complete" option (Firefox example). If you own the website, temporarily rename any "index...." file, and reference the directory locally. Then restore your "index...." file.

As part of Spring 4.1.1 onwards you now have full support of Java 8 Optional (original ticket) therefore in your example both requests will go via your single mapping endpoint as long as you replace required=false with Optional for your 3 params logout, name, password:

@RequestMapping (value = "/submit/id/{id}", method = RequestMethod.GET,   
 produces="text/xml")
public String showLoginWindow(@PathVariable("id") String id,
                              @RequestParam(value = "logout") Optional<String> logout,
                              @RequestParam("name") Optional<String> username,
                              @RequestParam("password") Optional<String> password,
                              @ModelAttribute("submitModel") SubmitModel model,
                              BindingResult errors) throws LoginException {...}

   DateTime date1 = new DateTime();

    date1 = Convert.ToDateTime(TextBox1.Text);
    Label1.Text = (date1.ToLongTimeString()); //11:00 AM
    Label2.Text = date1.ToLongDateString(); //Friday, November 1, 2019;
    Label3.Text = date1.ToString();
    Label4.Text = date1.ToShortDateString();
    Label5.Text = date1.ToShortTimeString();

If X inherits from Y, that has two somewhat orthogonal effects:

1. Y will provide default functionality for X, so the code for X only has to include stuff which is different from Y.
2. Almost anyplace a Y would be expected, an X may be used instead.

Although inheritance provides for both features, it is not hard to imagine circumstances where either could be of use without the other. No .net language I know of has a direct way of implementing the first without the second, though one could obtain such functionality by defining a base class which is never used directly, and having one or more classes that inherit directly from it without adding anything new (such classes could share all their code, but would not be substitutable for each other). Any CLR-compliant language, however, will allow the use of interfaces which provide the second feature of interfaces (substitutability) without the first (member reuse).

I got an error in Eclipse Mars version as "Build path specifies execution environment J2SE-1.5. There are no JREs installed in the workspace that are strictly compatible with this environment.

To resolve this issue, please do the following steps, "Right click on Project Choose Build path Choose Configure Build path Choose Libraries tab Select JRE System Library and click on Edit button Choose workspace default JRE and Finish

Problem will be resolved.

Maybe --force-reinstall would work, otherwise --ignore-installed should do the trick.

Since web is evolving quickly, some things changes with time. For security issues, you might want to use the rel="noopener" attribute in conjuncture with your target="_blank".

Like stated in Google Dev Documentation, the other page can access your window object with the window.opener property. Your external link should looks like this now:

<a href="http://www.starfall.com/" target="_blank" rel="noopener">Starfall</a>

I think this is best link for your solution to update postgres to 9.6

If you want just to get the value, you can use simple shell oneliner like this:

S=10; F=/sys/class/net/eth0/statistics/rx_bytes; X=`cat $F`; sleep $S; Y=`cat $F`; BPS="$(((Y-X)/S))"; echo $BPS

It will show you the average "received bytes per second" for period of 10 seconds (you can change period by changing S=10 parameter, and you can measure transmitted BPS instead of received BPS by using tx_bytes instead of rx_bytes). Don't forget to change eth0 to network device you want to monitor.

Of course, you are not limited to displaying the average rate (as mentioned in other answers, there are other tools that will show you much nicer output), but this solution is easily scriptable to do other things.

For example, the following shell script (split into multiple lines for readability) will execute offlineimap process only when 5-minute average transmit speed drops below 10kBPS (presumably, when some other bandwidth-consuming process finishes):

#!/bin/sh
S=300; F=/sys/class/net/eth0/statistics/tx_bytes
BPS=999999
while [ $BPS -gt 10000 ]
do
  X=`cat $F`; sleep $S; Y=`cat $F`; BPS="$(((Y-X)/S))";
  echo BPS is currently $BPS
done
offlineimap

Note that /sys/class/... is Linux specific (which is ok as submitter did choose linux tag), and needs non-archaic kernel. Shell code itself is /bin/sh compatible (so not only bash, but dash and other /bin/sh implementations will work) and /bin/sh is something that is really always installed.

With xidel:

xidel -s input.xml -e 'serialize(.,{"indent":true()})'
<root>
  <foo a="b">lorem</foo>
  <bar value="ipsum"/>
</root>

Or file:write("output.xml",.,{"indent":true()}) to save to a file.

"singleton" in spring is using bean factory get instance, then cache it; which singleton design pattern is strictly, the instance can only be retrieved from static get method, and the object can never be publicly instantiated.

The '\r' character is the carriage return, and the carriage return-newline pair is both needed for newline in a network virtual terminal session.

From the old telnet specification (RFC 854) (page 11):

The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").

However, from the latest specification (RFC5198) (page 13):

1. ...

2. In Net-ASCII, CR MUST NOT appear except when immediately followed by either NUL or LF, with the latter (CR LF) designating the "new line" function. Today and as specified above, CR should generally appear only when followed by LF. Because page layout is better done in other ways, because NUL has a special interpretation in some programming languages, and to avoid other types of confusion, CR NUL should preferably be avoided as specified above.

3. LF CR SHOULD NOT appear except as a side-effect of multiple CR LF sequences (e.g., CR LF CR LF).

So newline in Telnet should always be '\r\n' but most implementations have either not been updated, or keeps the old '\n\r' for backwards compatibility.

For python 3 use this

inp = list(map(int,input().split()))
#input => java is a programming language
#return as => ("java","is","a","programming","language")

input() accepts a string from STDIN.

split() splits the string about whitespace character and returns a list of strings.

map() passes each element of the 2nd argument to the first argument and returns a map object

Finally list() converts the map to a list

Using Java Web Start, you can install multiple JRE, then call what you need. On win, you can make a .bat file:

1- online version: <your_JRE_version\bin\javaws.exe> -localfile -J-Djnlp.application.href=<the url of .jnlp file.jnlp> -localfile -J "<path_temp_jnlp_file_.jnlp>"

2- launch from cache: <your_JRE_version\bin\javaws.exe> -localfile -J "<path_of_your_local_jnlp_file.jnlp>"

If you want to browse to a folder by default: For example "D:\Default_Folder" just initialise the "InitialFileName" attribute

Dim diaFolder As FileDialog

' Open the file dialog
Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
diaFolder.AllowMultiSelect = False
diaFolder.InitialFileName = "D:\Default_Folder"
diaFolder.Show

For Bootstrap 4 I find the following very handy because:

• the column on the right takes exactly the space it needs and will pull right
• while the left col always gets the maximum amount of space!.

It is the combination of col and col-auto which does the magic. So you don't have to define a col width (like col-2,...)

<div class="row">
    <div class="col">Left</div>
    <div class="col-auto">Right</div>
</div>

Ideal for aligning words, icons, buttons,... to the right.

An example to have this responsive on small devices:

<div class="row">
    <div class="col">Left</div>
    <div class="col-12 col-sm-auto">Right (Left on small)</div>
</div>

Elasticsearch 1.1+ has the Cardinality Aggregation which will give you a unique count

Note that it is actually an approximation and accuracy may diminish with high-cardinality datasets, but it's generally pretty accurate in my testing.

You can also tune the accuracy with the precision_threshold parameter. The trade-off, or course, is memory usage.

This graph from the docs shows how a higher precision_threshold leads to much more accurate results.

though npm install lodash would work, I think that it's a quick solution but there is a possibility that there are other modules not correctly installed in browser-sync.

lodash is part of browser-sync. The best solution is the one provided by Saebyeok. Re-install browser-sync and that should fix the problem.

Imagine a counter with an initial value of 0.

For every loop, increment the counter value by 1 using $counter = 0;

The final counter value returned by the loop will be the number of iterations of your for loop. Find the code below:

$counter = 0;
foreach ($Contents as $item) {
    $counter++;
    $item[number];// if there are 15 $item[number] in this foreach, I want get the value `: 15`
}

Try that.

Here is what worked for me. The heroku site is not being added to your known hosts. Go to window-other- show view-git-git repositories. From there clone the repository. Once you clone it, delete the repository that was just created and then import it from the file menu. Do this since when you clone the repository, it does not add it to the explorer view. Now you should have the git repository and the explorer view.

1. Remove Containers:

$ docker rm $(docker ps -aq)

2. Remove Images:

$ docker rmi $(docker images -q)

Instead of perform steps 1 and 2 you can do:

docker system prune

This command will remove:

• All stopped containers
• All volumes not used by at least one container
• All networks not used by at least one container
• All dangling images

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

The answer to "Given a class, see if instance has method (Ruby)" is better. Apparently Ruby has this built-in, and I somehow missed it. My answer is left for reference, regardless.

Ruby classes respond to the methods instance_methods and public_instance_methods. In Ruby 1.8, the first lists all instance method names in an array of strings, and the second restricts it to public methods. The second behavior is what you'd most likely want, since respond_to? restricts itself to public methods by default, as well.

Foo.public_instance_methods.include?('bar')

In Ruby 1.9, though, those methods return arrays of symbols.

Foo.public_instance_methods.include?(:bar)

If you're planning on doing this often, you might want to extend Module to include a shortcut method. (It may seem odd to assign this to Module instead of Class, but since that's where the instance_methods methods live, it's best to keep in line with that pattern.)

class Module
  def instance_respond_to?(method_name)
    public_instance_methods.include?(method_name)
  end
end

If you want to support both Ruby 1.8 and Ruby 1.9, that would be a convenient place to add the logic to search for both strings and symbols, as well.

I think the easiest way is

 ng-selected="$first"

The problem is you either haven't closed your if or you need an elseif:

create procedure checando(
    in nombrecillo varchar(30),
    in contrilla varchar(30), 
    out resultado int)
begin 

    if exists (select * from compas where nombre = nombrecillo and contrasenia = contrilla) then
        set resultado = 0;
    elseif exists (select * from compas where nombre = nombrecillo) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
end;

For a more simple and up to date answer:

backdrop-filter: blur(6px);

Note browser support is not perfect but in most cases a blur would be non essential.

("Jesse" or "jesse")

The above expression tests whether or not "Jesse" evaluates to True. If it does, then the expression will return it; otherwise, it will return "jesse". The expression is equivalent to writing:

"Jesse" if "Jesse" else "jesse"

Because "Jesse" is a non-empty string though, it will always evaluate to True and thus be returned:

>>> bool("Jesse")  # Non-empty strings evaluate to True in Python
True
>>> bool("")  # Empty strings evaluate to False
False
>>>
>>> ("Jesse" or "jesse")
'Jesse'
>>> ("" or "jesse")
'jesse'
>>>

This means that the expression:

name == ("Jesse" or "jesse")

is basically equivalent to writing this:

name == "Jesse"

In order to fix your problem, you can use the in operator:

# Test whether the value of name can be found in the tuple ("Jesse", "jesse")
if name in ("Jesse", "jesse"):

Or, you can lowercase the value of name with str.lower and then compare it to "jesse" directly:

# This will also handle inputs such as "JeSSe", "jESSE", "JESSE", etc.
if name.lower() == "jesse":

Additional attributes (in this case, the second onClick) will be ignored. So, instead of onclick calling both fbLikeDump(); and WriteCookie();, it will only call fbLikeDump();. To fix, simply define a single onclick attribute and call both functions within it:

<input type="button" value="Don't show this again! " onclick="fbLikeDump();WriteCookie();" />

Here is an approach where Inkscape is called by Python.

Note that it suppresses certain crufty output that Inkscape writes to the console (specifically, stderr and stdout) during normal error-free operation. The output is captured in two string variables, out and err.

import subprocess               # May want to use subprocess32 instead

cmd_list = [ '/full/path/to/inkscape', '-z', 
             '--export-png', '/path/to/output.png',
             '--export-width', 100,
             '--export-height', 100,
             '/path/to/input.svg' ]

# Invoke the command.  Divert output that normally goes to stdout or stderr.
p = subprocess.Popen( cmd_list, stdout=subprocess.PIPE, stderr=subprocess.PIPE )

# Below, < out > and < err > are strings or < None >, derived from stdout and stderr.
out, err = p.communicate()      # Waits for process to terminate

# Maybe do something with stdout output that is in < out >
# Maybe do something with stderr output that is in < err >

if p.returncode:
    raise Exception( 'Inkscape error: ' + (err or '?')  )

For example, when running a particular job on my Mac OS system, out ended up being:

Background RRGGBBAA: ffffff00
Area 0:0:339:339 exported to 100 x 100 pixels (72.4584 dpi)
Bitmap saved as: /path/to/output.png

(The input svg file had a size of 339 by 339 pixels.)

that depends on what kind of information are you passing to the conditional..

sometimes your result will be null or undefined or '' or 0, for my simple validation i use this if.

( $('#id').val() == '0' || $('#id').val() == '' || $('#id').val() == 'undefined' || $('#id').val() == null )

NOTE: null != 'null'

You could actually use xlsread to accomplish this. After first placing your sample data above in a file 'input_file.csv', here is an example for how you can get the numeric values, text values, and the raw data in the file from the three outputs from xlsread:

>> [numData,textData,rawData] = xlsread('input_file.csv')

numData =     % An array of the numeric values from the file

   51.9358    4.1833
   51.9354    4.1841
   51.9352    4.1846
   51.9343    4.1864
   51.9343    4.1864
   51.9341    4.1869


textData =    % A cell array of strings for the text values from the file

    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'


rawData =     % All the data from the file (numeric and text) in a cell array

    'ABC'    [51.9358]    [4.1833]
    'ABC'    [51.9354]    [4.1841]
    'ABC'    [51.9352]    [4.1846]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9341]    [4.1869]

You can then perform whatever processing you need to on the numeric data, then resave a subset of the rows of data to a new file using xlswrite. Here's an example:

index = sqrt(sum(numData.^2,2)) >= 50;  % Find the rows where the point is
                                        %   at a distance of 50 or greater
                                        %   from the origin
xlswrite('output_file.csv',rawData(index,:));  % Write those rows to a new file

Here is the snippet that I am using to get the MD5 for a given string:

$text = "text goes here..."
$md5  = [Security.Cryptography.MD5CryptoServiceProvider]::new()
$utf8 = [Text.UTF8Encoding]::UTF8
$bytes= $md5.ComputeHash($utf8.GetBytes($text))
$hash = [string]::Concat($bytes.foreach{$_.ToString("x2")}) 

You didn't provide us which operating system are you on? If it is a Linux, make sure you have scipy installed as well, after that just do

pip install -U scikit-learn

If you are on windows you might want to check out these pages.

Well, I guess the question is, what do you mean by 'roll back'? If you can't reset because it's public and you want to keep the commit history intact, do you mean you just want your working copy to reflect a specific commit? Use git checkout and the commit hash.

Edit: As was pointed out in the comments, using git checkout without specifying a branch will leave you in a "no branch" state. Use git checkout <commit> -b <branchname> to checkout into a branch, or git checkout <commit> . to checkout into the current branch.

CONVERT(date, [_Date_Time]) AS 'Short_Date'

I have 2 accounts on github, and here is what I did (on linux) to make it work.

Keys

• Create 2 pair of rsa keys, via ssh-keygen, name them properly, so that make life easier.
• Add private keys to local agent via ssh-add path_to_private_key
• For each github account, upload a (distinct) public key.

Configuration

~/.ssh/config

Host github-kc
    Hostname        github.com
    User git
    IdentityFile    ~/.ssh/github_rsa_kc.pub
    # LogLevel DEBUG3

Host github-abc
    Hostname        github.com
    User git
    IdentityFile    ~/.ssh/github_rsa_abc.pub
    # LogLevel DEBUG3

Set remote url for repo:

• For repo in Host github-kc:

  git remote set-url origin git@github-kc:kuchaguangjie/pygtrans.git
  

• For repo in Host github-abc:

  git remote set-url origin git@github-abc:abcdefg/yyy.git
  

Explaination

Options in ~/.ssh/config:

• Host github-<identify_specific_user>
  Host could be any value that could identify a host plus an account, it don't need to be a real host, e.g github-kc identify one of my account on github for my local laptop,
  

  When set remote url for a git repo, this is the value to put after git@, that's how a repo maps to a Host, e.g git remote set-url origin git@github-kc:kuchaguangjie/pygtrans.git

• 
  
• [Following are sub options of Host]
• Hostname
  specify the actual hostname, just use github.com for github,
• User git
  the user is always git for github,
• IdentityFile
  specify key to use, just put the path the a public key,
• LogLevel
  specify log level to debug, if any issue, DEBUG3 gives the most detailed info.

I collected many topics to make universal function with many outputs (years, months, days, hours, minutes, seconds) with string or parse to int and direction +- if you need to know what side is direction of the difference.

Use example:

    $date1='2016-05-27 02:00:00';
    $format='Y-m-d H:i:s';

    echo timeDifference($date1, $format, '2017-08-30 00:01:59', $format); 
    #1 years 3 months 2 days 22 hours 1 minutes 59 seconds (string)

    echo timeDifference($date1, $format, '2017-08-30 00:01:59', $format,false, '%a days %h hours');
    #459 days 22 hours (string)

    echo timeDifference('2016-05-27 00:00:00', $format, '2017-08-30 00:01:59', $format,true, '%d days -> %H:%I:%S', true);
    #-3 days -> 00:01:59 (string)

    echo timeDifference($date1, $format, '2016-05-27 00:05:51', $format, false, 'seconds');
    #9 (string)

    echo timeDifference($date1, $format, '2016-05-27 07:00:00', $format, false, 'hours');
    #5 (string)

    echo timeDifference($date1, $format, '2016-05-27 07:00:00', $format, true, 'hours');
    #-5 (string)

    echo timeDifference($date1, $format, '2016-05-27 07:00:00', $format, true, 'hours',true);
    #-5 (int)

consider the approach of melt() to convert the nested list to a tall format first:

myjson <- jsonlite:fromJSON(file("test.json"))
tall <- reshape2::melt(myjson)[, c("L1", "L2", "L3", "value")]
    L1     L2         L3 value

7 2016 sweden population     9
8 2016 sweden        GNP     8

followed by dcast() then to wide again into a tidy dataset where each variable forms a a column and each observation forms a row:

wide <- reshape2::dcast(tall, L1+L2~L3) 
# left side of the formula defines the rows/observations and the 
# right side defines the variables/measurements
    L1     L2 GNP population

A cross platform 2D graphics library for .Net is The Little Vector Library You could use it in conjunction with Unity 3D (recommended) or Xamarin, for example, to create 2D graphics on a variety of platforms.

If I run the following:

echo '<?php echo $foo; ?>' | php

I get an error:

PHP Notice:  Undefined variable: foo in /home/altern8/- on line 1

If I run the following:

echo '<?php if ( isset($foo) ) { echo $foo; } ?>' | php

I do not get the error.

If I have a variable that should be set, I usually do something like the following.

$foo = isset($foo) ? $foo : null;

or

if ( ! isset($foo) ) $foo = null;

That way, later in the script, I can safely use $foo and know that it "is set", and that it defaults to null. Later I can if ( is_null($foo) ) { /* ... */ } if I need to and know for certain that the variable exists, even if it is null.

The full isset documentation reads a little more than just what was initially pasted. Yes, it returns false for a variable that was previously set but is now null, but it also returns false if a variable has not yet been set (ever) and for any variable that has been marked as unset. It also notes that the NULL byte ("\0") is not considered null and will return true.

Determine whether a variable is set.

If a variable has been unset with unset(), it will no longer be set. isset() will return FALSE if testing a variable that has been set to NULL. Also note that a NULL byte ("\0") is not equivalent to the PHP NULL constant.

I've slightly modified Peter's answer here to create a reusable, non-interactive shell script called git-split.sh:

#!/bin/sh

if [[ $# -ne 2 ]] ; then
  echo "Usage: git-split.sh original copy"
  exit 0
fi

git mv "$1" "$2"
git commit -n -m "Split history $1 to $2 - rename file to target-name"
REV=`git rev-parse HEAD`
git reset --hard HEAD^
git mv "$1" temp
git commit -n -m "Split history $1 to $2 - rename source-file to temp"
git merge $REV
git commit -a -n -m "Split history $1 to $2 - resolve conflict and keep both files"
git mv temp "$1"
git commit -n -m "Split history $1 to $2 - restore name of source-file"

In Drupal

I have a Drupal 6 site. I was on the admin "modules" page, and noticed the tables had this exact feature!

Looking at the code, it seems to be implemented by a file called tableheader.js. It applies the feature on all tables with the class sticky-enabled.

For a Drupal site, I'd like to be able to make use of that tableheader.js module as-is for user content. tableheader.js doesn't seem to be present on user content pages in Drupal. I posted a forum message to ask how to modify the Drupal theme so it's available. According to a response, tableheader.js can be added to a Drupal theme using drupal_add_js() in the theme's template.php as follows:

drupal_add_js('misc/tableheader.js', 'core');

You don't "commit the folder" - you add the folder, as you have done, and then simply commit all changes. The command should be:

git add foldername
git commit -m "commit operation"

From what I understand the key difference is that live() keeps an eye open for new DOM elements that match the selector you are working on, whereas click() (or bind('click')) attach the event hook and are finished.

Given that alot of your code is loaded asynchronously, using live() will make your life alot easier. If you don't know exactly the code you are loading but you do know what kind of elements you will be listening to, then using this function makes perfect sense.

In terms of performance gains, one alternative to using live() would be to implement an AJAX callback function to re-bind the event hooks.

var ajaxCallback = function(){
 $('*').unbind('click');
 $('.something').bind('click', someFunction);
 $('.somethingElse').bind('click', someOtherFunction);
}

You will need to keep proper track of your event hooks and make sure this function is rebinding the proper events.

p.s. Ajax methods .get(), .post(), .load() and .ajax() all let you specify a callback function.

NO,but there are some other options to implement default value. There are some good blog posts on the subject, but here are some specific examples.

// Both parameters are optional, use empty string for default value
func Concat1(a string, b int) string {
  if a == "" {
    a = "default-a"
  }
  if b == 0 {
    b = 5
  }

  return fmt.Sprintf("%s%d", a, b)
}

// a is required, b is optional.
// Only the first value in b_optional will be used.
func Concat2(a string, b_optional ...int) string {
  b := 5
  if len(b_optional) > 0 {
    b = b_optional[0]
  }

  return fmt.Sprintf("%s%d", a, b)
}

// A declarative default value syntax
// Empty values will be replaced with defaults
type Parameters struct {
  A string `default:"default-a"` // this only works with strings
  B string // default is 5
}

func Concat3(prm Parameters) string {
  typ := reflect.TypeOf(prm)

  if prm.A == "" {
    f, _ := typ.FieldByName("A")
    prm.A = f.Tag.Get("default")
  }

  if prm.B == 0 {
    prm.B = 5
  }

  return fmt.Sprintf("%s%d", prm.A, prm.B)
}

func Concat4(args ...interface{}) string {
  a := "default-a"
  b := 5

  for _, arg := range args {
    switch t := arg.(type) {
      case string:
        a = t
      case int:
        b = t
      default:
        panic("Unknown argument")
    }
  }

  return fmt.Sprintf("%s%d", a, b)
}

If you don't overly care about the 'randomness' of the low-order bits, just rand() % HI_VAL.

Also:

(double)rand() / (double)RAND_MAX;  // lazy way to get [0.0, 1.0)

Here is a list of available builds for debian: https://github.com/nodesource/distributions/tree/master/deb

For this example, lets assume you want version 14 (LTS at the time of writing)

We can download this script from github, execute it and install the version of node we want. For security reasons it's a good idea to read the script prior to executing it.

curl -sL https://raw.githubusercontent.com/nodesource/distributions/master/deb/setup_14.x | bash
apt-get install -y nodejs # may or may not require sudo based on your setup 

I like this approach because it doesn't require extraneous dependencies like nvm to target specific versions

If you are building for a different distro or architecture you can find more builds here https://nodejs.org/dist/

function GetPixel(context, x, y)
{
    var p = context.getImageData(x, y, 1, 1).data; 
    var hex = "#" + ("000000" + rgbToHex(p[0], p[1], p[2])).slice(-6);  
    return hex;
}

function rgbToHex(r, g, b) {
    if (r > 255 || g > 255 || b > 255)
        throw "Invalid color component";
    return ((r << 16) | (g << 8) | b).toString(16);
}

Several of the responses rely on an exception being thrown and having it handled in the OnException override. In my case, I wanted to return statuses such as bad request if the user, say, had passed in a bad ID. What works for me is to use the ControllerContext:

var jsonResult = new JsonResult { JsonRequestBehavior = JsonRequestBehavior.AllowGet, Data = "whoops" };

ControllerContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.BadRequest;

return jsonResult;

Depending on your needs, a simple divide-and-conquer strategy can be used. It won't converge as fast as some other methods but it may be a lot easier for a novice to understand. In addition, since it's an O(log n) algorithm (halving the search space each iteration), the worst case for a 32-bit float will be 32 iterations.

Let's say you want the square root of 62.104. You pick a value halfway between 0 and that, and square it. If the square is higher than your number, you need to concentrate on numbers less than the midpoint. If it's too low, concentrate on those higher.

With real math, you could keep dividing the search space in two forever (if it doesn't have a rational square root). In reality, computers will eventually run out of precision and you'll have your approximation. The following C program illustrates the point:

#include <stdio.h>
#include <stdlib.h>

int main (int argc, char *argv[]) {
    float val, low, high, mid, oldmid, midsqr;
    int step = 0;

    // Get argument, force to non-negative.

    if (argc < 2) {
        printf ("Usage: sqrt <number>\n");
        return 1;
    }
    val = fabs (atof (argv[1]));

    // Set initial bounds and print heading.

    low = 0;
    high = mid = val;
    oldmid = -1;

    printf ("%4s  %10s  %10s  %10s  %10s  %10s    %s\n",
        "Step", "Number", "Low", "High", "Mid", "Square", "Result");

    // Keep going until accurate enough.

    while (fabs(oldmid - mid) >= 0.00001) {
        oldmid = mid;

        // Get midpoint and see if we need lower or higher.

        mid = (high + low) / 2;
        midsqr = mid * mid;
        printf ("%4d  %10.4f  %10.4f  %10.4f  %10.4f  %10.4f  ",
            ++step, val, low, high, mid, midsqr);
        if (mid * mid > val) {
            high = mid;
            printf ("- too high\n");
        } else {
            low = mid;
            printf ("- too low\n");
        }
    }

    // Desired accuracy reached, print it.

    printf ("sqrt(%.4f) = %.4f\n", val, mid);
    return 0;
}

    $file = escapeshellarg($file);
    $mime = shell_exec("file -bi " . $file);

For me, nothing of this does work - mime_content_type is deprecated, finfo is not installed, and shell_exec is not allowed.

It's unclear if the original problem was the same problem I had: wanting to max CPU threads on computation inside a loop while preserving the iterator's value and keeping inline to avoid passing a ton of variables to a worker function.

for (int i = 0; i < 300; i++)
{
    Task.Run(() => {
        var x = ComputeStuff(datavector, i); // value of i was incorrect
        var y = ComputeMoreStuff(x);
        // ...
    });
}

I got this to work by changing the outer iterator and localizing its value with a gate.

for (int ii = 0; ii < 300; ii++)
{
    System.Threading.CountdownEvent handoff = new System.Threading.CountdownEvent(1);
    Task.Run(() => {
        int i = ii;
        handoff.Signal();

        var x = ComputeStuff(datavector, i);
        var y = ComputeMoreStuff(x);
        // ...

    });
    handoff.Wait();
}

Sometimes we know in advance that the value stored in a given integer variable will always be positive-when it is being used to only count things, for example. In such a case we can declare the variable to be unsigned, as in, unsigned int num student;. With such a declaration, the range of permissible integer values (for a 32-bit compiler) will shift from the range -2147483648 to +2147483647 to range 0 to 4294967295. Thus, declaring an integer as unsigned almost doubles the size of the largest possible value that it can otherwise hold.

SendRedirect() will search the content between the servers. it is slow because it has to intimate the browser by sending the URL of the content. then browser will create a new request for the content within the same server or in another one.

RquestDispatcher is for searching the content within the server i think. its the server side process and it is faster compare to the SendRedirect() method. but the thing is that it will not intimate the browser in which server it is searching the required date or content, neither it will not ask the browser to change the URL in URL tab. so it causes little inconvenience to the user.

In SQL Server 2008, you can use:

CONVERT(DATE, getdate(), 101)

This might not be the exact thing you are looking for, but you can create a very similar effect by using rgba in combination with linear-gradient:

  background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);

This creates a linear-gradient from black with 50% opacity (rgba(0,0,0,.5)) to transparent (rgba(0,0,0,0)) which starts being competently transparent 30% from the top. You can play with those values to create your desired effect. You can have it on a different side by adding a deg-value (linear-gradient(90deg, rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%)) or switching the colors around. If you want really complex shadows like different angles on different sides you could even start layering linear-gradient.

Here is a snippet to see it in action:

.box {_x000D_
  background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);_x000D_
}_x000D_
_x000D_
.text {_x000D_
  padding: 20px;_x000D_
}

<div class="box">_x000D_
  <div class="text">_x000D_
    Lorem ipsum ...._x000D_
  </div>_x000D_
</div>

It might be a wrong path. Ensure in your main app file you have:

app.use(express.static(path.join(__dirname,"public")));

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

The problem seems to be in the way how ng-model works with input and overwrites the name object, making it lost for ng-repeat.

As a workaround, one can use the following code:

<div ng-repeat="name in names">
    Value: {{name}}
    <input ng-model="names[$index]">                         
</div>

The blick tag is deprecated, and the effect is kind of old :) Current browsers don't support it anymore. Anyway, if you need the blinking effect, you should use javascript or CSS solutions.

Running PHP as a CGI means that you basically tell your web server the location of the PHP executable file, and the server runs that executable

whereas

PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle strenuous loads. PHP-FPM maintains pools (workers that can respond to PHP requests) to accomplish this. PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments

However, there are pros and cons to both and one should choose as per their specific use case.

I found info on this link for fastcgi vs fpm quite helpful in choosing which handler to use in my scenario.

VAR1=value1 VAR2=value2 myScript args ...

It sounds like you're trying to SELECT a column that doesn't exist.

Perhaps you're trying to ORDER BY a column that doesn't exist?

Any typos in your SQL statement?

I have spent two solid days working on this so I just thought I'd share my solution as well. As of 26/11/10 the current branch is 1.2.X so that means you'll have to have the following in you settings.py:

MEDIA_ROOT = "<path_to_files>" (i.e. /home/project/django/app/templates/static)
MEDIA_URL = "http://localhost:8000/static/"

*(remember that MEDIA_ROOT is where the files are and MEDIA_URL is a constant that you use in your templates.)*

Then in you url.py place the following:

import settings

# stuff

(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),

Then in your html you can use:

<img src="{{ MEDIA_URL }}foo.jpg">

The way django works (as far as I can figure is:

1. In the html file it replaces MEDIA_URL with the MEDIA_URL path found in setting.py
2. It looks in url.py to find any matches for the MEDIA_URL and then if it finds a match (like r'^static/(?P.)$'* relates to http://localhost:8000/static/) it searches for the file in the MEDIA_ROOT and then loads it

The jQuery selector for all h tags (h1, h2 etc) is " :header ". For example, if you wanted to make all h tags red in color with jQuery, use:

$(':header').css("color","red")

The IF statement does not support logical operators AND and OR. Cascading IF statements make an implicit conjunction:

IF Exist File1.Dat IF Exist File2.Dat GOTO FILE12_EXIST_LABEL

If File1.Dat and File2.Dat exist then jump to the label FILE12_EXIST_LABEL.

See also: IF /?

You have to actually call some method to create the directories. Just creating a file object will not create the corresponding file or directory on the file system.

You can use File#mkdirs() method to create the directory: -

theFile.mkdirs();

Difference between File#mkdir() and File#mkdirs() is that, the later will create any intermediate directory if it does not exist.

Note, this method has been deprecated for more recent versions of django! (> 1.3)

An alternative answer, you could add this to the top of my_script.py

from django.core.management import setup_environ
import settings
setup_environ(settings)

and execute my_script.py just with python in the directory where you have settings.py but this is a bit hacky.

$ python my_script.py

Generally the first 2 package "words" are your web address in reverse. (You'd have 3 here as convention, if you had a subdomain.)

So something stackoverflow produces would likely be in package com.stackoverflow.whatever.customname

something asp.net produces might be called net.asp.whatever.customname.omg.srsly

something from mysubdomain.toplevel.com would be com.toplevel.mysubdomain.whatever

Beyond that simple convention, the sky's the limit. This is an old linux convention for something that I cannot recall exactly...

In many cases an element must be positioned for z-index to work.

Indeed, applying position: relative to the elements in the question would likely solve the problem (but there's not enough code provided to know for sure).

Actually, position: fixed, position: absolute and position: sticky will also enable z-index, but those values also change the layout. With position: relative the layout isn't disturbed.

Essentially, as long as the element isn't position: static (the default setting) it is considered positioned and z-index will work.

Many answers to "Why isn't z-index working?" questions assert that z-index only works on positioned elements. As of CSS3, this is no longer true.

Elements that are flex items or grid items can use z-index even when position is static.

From the specs:

4.3. Flex Item Z-Ordering

Flex items paint exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

5.4. Z-axis Ordering: the z-index property

The painting order of grid items is exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

Here's a demonstration of z-index working on non-positioned flex items: https://jsfiddle.net/m0wddwxs/

The Public Key is not stored in the PEM file as some people think. The following DER structure is present on the Private Key File:

openssl rsa -text -in mykey.pem

RSAPrivateKey ::= SEQUENCE {
  version           Version,
  modulus           INTEGER,  -- n
  publicExponent    INTEGER,  -- e
  privateExponent   INTEGER,  -- d
  prime1            INTEGER,  -- p
  prime2            INTEGER,  -- q
  exponent1         INTEGER,  -- d mod (p-1)
  exponent2         INTEGER,  -- d mod (q-1)
  coefficient       INTEGER,  -- (inverse of q) mod p
  otherPrimeInfos   OtherPrimeInfos OPTIONAL
}

So there is enough data to calculate the Public Key (modulus and public exponent), which is what openssl rsa -in mykey.pem -pubout does

What you can also do is to use apt-get:

apt-get install python3-pip

In my experience this works pretty fluent too, plus you get all the benefits from apt-get.

Something like this - for each line read into string variable a:

>>> a = "123,456"
>>> b = a.split(",")
>>> b
['123', '456']
>>> c = [int(e) for e in b]
>>> c
[123, 456]
>>> x, y = c
>>> x
123
>>> y
456

Now you can do what is necessary with x and y as assigned, which are integers.

I know that this solution is a little different from the OP's case, but as you may have been redirected here from searching on google the title of this question, as I did, maybe you're facing the same problem I had.
Sometimes you get this error because your date time is not valid, i.e. your date (in string format) points to a day which exceeds the number of days of that month! e.g.: CONVERT(Datetime, '2015-06-31') caused me this error, while I was converting a statement from MySql (which didn't argue! and makes the error really harder to catch) to SQL Server.

You could wrap your h1 tags in another div and then the first one would be the first-child. That div doesn't even need styles. It's just a way to segregate those children.

<div class="h1-holder">
    <h1>Title 1</h1>
    <h1>Title 2</h1>
</div>

This should work in most versions of PHP 4+. Array map using anonymous functions is not supported below 5.3.

Also the foreach examples will throw a warning when using strict PHP error handling.

Here is a small multi-dimensional key renaming function. It can also be used to process arrays to have the correct keys for integrity throughout your app. It will not throw any errors when a key does not exist.

function multi_rename_key(&$array, $old_keys, $new_keys)
{
    if(!is_array($array)){
        ($array=="") ? $array=array() : false;
        return $array;
    }
    foreach($array as &$arr){
        if (is_array($old_keys))
        {
            foreach($new_keys as $k => $new_key)
            {
                (isset($old_keys[$k])) ? true : $old_keys[$k]=NULL;
                $arr[$new_key] = (isset($arr[$old_keys[$k]]) ? $arr[$old_keys[$k]] : null);
                unset($arr[$old_keys[$k]]);
            }
        }else{
            $arr[$new_keys] = (isset($arr[$old_keys]) ? $arr[$old_keys] : null);
            unset($arr[$old_keys]);
        }
    }
    return $array;
}

Usage is simple. You can either change a single key like in your example:

multi_rename_key($tags, "url", "value");

or a more complex multikey

multi_rename_key($tags, array("url","name"), array("value","title"));

It uses similar syntax as preg_replace() where the amount of $old_keys and $new_keys should be the same. However when they are not a blank key is added. This means you can use it to add a sort if schema to your array.

Use this all the time, hope it helps!

check whether you import FormsModule. There's no ngControl in the new forms angular 2 release version. you have to change your template to as an example

<div class="row">
    <div class="form-group col-sm-7 col-md-5">
        <label for="name">Name</label>
        <input type="text" class="form-control" required
               [(ngModel)]="user.name"
               name="name" #name="ngModel">
        <div [hidden]="name.valid || name.pristine" class="alert alert-danger">
            Name is required
        </div>
    </div>
</div>

Like this:

{% if age > 18 %}
    {% with patient as p %}
    <my html here>
    {% endwith %}
{% else %}
    {% with patient.parent as p %}
    <my html here>
    {% endwith %}
{% endif %}

If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:

p = (age > 18 && patient) or patient.parent

and then just use {{ p }} in the template.

CodePress does this, as does EditArea. Both are open source.

With docker 1.3, there is a new command docker exec. This allows you to enter a running container:

docker exec -it [container-id] bash

SVG animations are probably a better solution to this problem. You won't need to worry about writing CSS and compared to GIFs, you'll get better resolution and alpha transparency. Some very good SVG loading animations that you can use are here: http://samherbert.net/svg-loaders/

You can also use those animations directly through a service I built: https://svgbox.net/iconset/loaders. It allows you to customize the fill and direct usage (hotlinking) is permitted.

To accomplish what you want to do with jQuery, you probably should have a loading info element hidden and use .show() when you want to show the loader. For eg, this code shows the loader after one second:

setTimeout(function() {
  $("#load").show();
}, 1000)

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>

<div id="load" style="display:none">
    Please wait... 
    <img src="//s.svgbox.net/loaders.svg?fill=maroon&ic=tail-spin" 
         style="width:24px">
</div>

i would recommend Modern UI for WPF .

It has a very active maintainer it is awesome and free!

I'm currently porting some projects to MUI, first (and meanwhile second) impression is just wow!

To see MUI in action you could download XAML Spy which is based on MUI.

EDIT: Using Modern UI for WPF a few months and i'm loving it!

Try:

intent.setType("message/rfc822");

Try downloading the certificates/profiles directly from the member centre rather than doing it from Xcode.

It worked for me when I manually downloaded them from the member centre.

You can simply use background CSS property as follows:

tr:hover{
    background: #F1F1F2;    
}

Working example

with 'nonlocal' inner functions(ie;nested inner functions) can get read & 'write' permission for that specific variable of the outer parent function. And nonlocal can be used only inside inner functions eg:

a = 10
def Outer(msg):
    a = 20
    b = 30
    def Inner():
        c = 50
        d = 60
        print("MU LCL =",locals())
        nonlocal a
        a = 100
        ans = a+c
        print("Hello from Inner",ans)       
        print("value of a Inner : ",a)
    Inner()
    print("value of a Outer : ",a)

res = Outer("Hello World")
print(res)
print("value of a Global : ",a)

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

you might want to start with max(trans_seq_no) + 1.

watch:

SQL> create table my_numbers(my_number number not null primary key);

Table created.

SQL> insert into my_numbers(select rownum from user_objects);

260 rows created.

SQL> select max(my_number) from my_numbers;

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

First you will need to install node definitions for Typescript. You can find the definitions file here:

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/node/node.d.ts

Once you've got file, just add the reference to your .ts file like this:

/// <reference path="path/to/node.d.ts" />

Then you can code your typescript class that read/writes, using the Node File System module. Your typescript class myClass.ts can look like this:

/// <reference path="path/to/node.d.ts" />

class MyClass {

    // Here we import the File System module of node
    private fs = require('fs');

    constructor() { }

    createFile() {

        this.fs.writeFile('file.txt', 'I am cool!',  function(err) {
            if (err) {
                return console.error(err);
            }
            console.log("File created!");
        });
    }

    showFile() {

        this.fs.readFile('file.txt', function (err, data) {
            if (err) {
                return console.error(err);
            }
            console.log("Asynchronous read: " + data.toString());
        });
    }
}

// Usage
// var obj = new MyClass();
// obj.createFile();
// obj.showFile();

Once you transpile your .ts file to a javascript (check out here if you don't know how to do it), you can run your javascript file with node and let the magic work:

> node myClass.js

Entity interface

public interface Entity<I> extends Serializable {

/**
 * @return entity identity
 */
I getId();

/**
 * @return HashCode of entity identity
 */
int identityHashCode();

/**
 * @param other
 *            Other entity
 * @return true if identities of entities are equal
 */
boolean identityEquals(Entity<?> other);
}

Basic implementation for all Entities, simplifies Equals/Hashcode implementations:

public abstract class AbstractEntity<I> implements Entity<I> {

@Override
public final boolean identityEquals(Entity<?> other) {
    if (getId() == null) {
        return false;
    }
    return getId().equals(other.getId());
}

@Override
public final int identityHashCode() {
    return new HashCodeBuilder().append(this.getId()).toHashCode();
}

@Override
public final int hashCode() {
    return identityHashCode();
}

@Override
public final boolean equals(final Object o) {
    if (this == o) {
        return true;
    }
    if ((o == null) || (getClass() != o.getClass())) {
        return false;
    }

    return identityEquals((Entity<?>) o);
}

@Override
public String toString() {
    return getClass().getSimpleName() + ": " + identity();
    // OR 
    // return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}

Room Entity impl:

@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;

@Column(name = "number") 
private String number; //immutable

@Column(name = "capacity")
private Integer capacity;

@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable

Room() {
    // default constructor
}

public Room(Building building, String number) {
    // constructor with required field
    notNull(building, "Method called with null parameter (application)");
    notNull(number, "Method called with null parameter (name)");

    this.building = building;
    this.number = number;
}

public Integer getId(){
    return id;
}

public Building getBuilding() {
    return building;
}

public String getNumber() {
    return number;
}


public void setCapacity(Integer capacity) {
    this.capacity = capacity;
}

//no setters for number, building nor id
}

I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).

You can't avoid polling, there isn't any event for href change.

Using intervals is quite light anyways if you don't go overboard. Checking the href every 50ms or so will not have any significant effect on performance if you're worried about that.

After replacing the character, you need to be asign to the variable.

var tt = "88,9827";
tt = tt.replace(/,/g, '.')
alert(tt)

In the alert box it will shows 88.9827

If your data changes a lot, you can use

 mAdapter.notifyItemRangeChanged(0, yourData.size());

or some single items in your data set changes, your can use

 mAdapter.notifyItemChanged(pos);

For detailed methods usage, you can refer the doc, in a way, try not to directly use mAdapter.notifyDataSetChanged().

This is all you need

Set wbOOR = ActiveWorkbook

This cannot be done with CMake. You have to generate two separate build folders. One for the x86 NMake build and one for the x64 NMake build. You cannot generate a single Visual Studio project covering both architectures with CMake, either.

To build Visual Studio projects from the command line for both 32-bit and 64-bit without starting a Visual Studio command prompt, use the regular Visual Studio generators.

For CMake 3.13 or newer, run the following commands:

cmake -G "Visual Studio 16 2019" -A Win32 -S \path_to_source\ -B "build32"
cmake -G "Visual Studio 16 2019" -A x64 -S \path_to_source\ -B "build64"
cmake --build build32 --config Release
cmake --build build64 --config Release

For earlier versions of CMake, run the following commands:

mkdir build32 & pushd build32
cmake -G "Visual Studio 15 2017" \path_to_source\
popd
mkdir build64 & pushd build64
cmake -G "Visual Studio 15 2017 Win64" \path_to_source\
popd
cmake --build build32 --config Release
cmake --build build64 --config Release

CMake generated projects that use one of the Visual Studio generators can be built from the command line with using the option --build followed by the build directory. The --config option specifies the build configuration.

Also we can try like this,

 string[] selectedColumns = new[] { "Column1","Column2"};

 DataTable dt= new DataView(fromDataTable).ToTable(false, selectedColumns);

You can put custom image in radiobutton like normal button. for that create one XML file in drawable folder e.g

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/sub_screens_aus_hl" 
    android:state_pressed="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_checked="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_focused="true" />
<item android:drawable="@drawable/sub_screens_aus_dis" />  
</selector> 

Here you can use 3 different images for radiobutton

and use this file to RadioButton like:

android:button="@drawable/aus"
android:layout_height="120dp"
android:layout_width="wrap_content" 

I use testproxy to do this.

npm install testproxy

testproxy http://10.0.2.2

You then get the url (and QR code) you can access on your mobile device. It even works with virtual machines you can't reach by just entering the IP of your dev machine.

You can also do

console.log("a = %o, b = %o", a, b);

where a and b are objects.

You can use the static method Enum.GetNames which returns an array representing the names of all the items in the enum. The length property of this array equals the number of items defined in the enum

var myEnumMemberCount = Enum.GetNames(typeof(MyEnum)).Length;

In jQuery you can do like this.

function random_no(){_x000D_
     var ran=Math.random();_x000D_
     jQuery('#random_no_container').html(ran);_x000D_
}_x000D_
           _x000D_
window.setInterval(function(){_x000D_
       /// call your function here_x000D_
      random_no();_x000D_
}, 6000);  // Change Interval here to test. For eg: 5000 for 5 sec

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="random_no_container">_x000D_
      Hello. Here you can see random numbers after every 6 sec_x000D_
</div>

This is not intended to directly answer the OP, but I wanted to share some related ideas.

I was very interested in @steveha answer above, which seemed to give an example where duck typing seems to break. On second thought, however, his example suggests that duck typing is hard to conform to, but it does not suggest that str deserves any special handling.

After all, a non-str type (e.g., a user-defined type that maintains some complicated recursive structures) may cause @steveha srepr function to cause an infinite recursion. While this is admittedly rather unlikely, we can't ignore this possibility. Therefore, rather than special-casing str in srepr, we should clarify what we want srepr to do when an infinite recursion results.

It may seem that one reasonable approach is to simply break the recursion in srepr the moment list(arg) == [arg]. This would, in fact, completely solve the problem with str, without any isinstance.

However, a really complicated recursive structure may cause an infinite loop where list(arg) == [arg] never happens. Therefore, while the above check is useful, it's not sufficient. We need something like a hard limit on the recursion depth.

My point is that if you plan to handle arbitrary argument types, handling str via duck typing is far, far easier than handling the more general types you may (theoretically) encounter. So if you feel the need to exclude str instances, you should instead demand that the argument is an instance of one of the few types that you explicitly specify.

C++ has Automatic variables - not Stack variables.

Automatic variable means that C++ compiler handles memory allocation / free by itself. C++ can automatically handle objects of any class - no matter whether it has dynamically allocated members or not. It's achieved by strong guarantee of C++ that object's destructor will be called automatically when execution is going out of scope where automatic variable was declared. Inside of a C++ object can be a lot of dynamic allocations with new in constructor, and when such an object is declared as an automatic variable - all dynamic allocations will be performed, and freed then in destructor.

Stack variables in C can't be dynamically allocated. Stack in C can store pointers, or fixed arrays or structs - all of fixed size, and these things are being allocated in memory in linear order. When a C program frees a stack variable - it just moves stack pointer back and nothing more.

Even though C++ programs can use Stack memory segment for storing primitive types, function's args, or other, - it's all decided by C++ compiler, not by program developer. Thus, it is conceptually wrong to equal C++ automatic variables and C stack variables.

I wrote about this recently at http://snmaynard.com/2012/12/21/node-error-handling/. A new feature of node in version 0.8 is domains and allow you to combine all the forms of error handling into one easier manage form. You can read about them in my post.

You can also use something like Bugsnag to track your uncaught exceptions and be notified via email, chatroom or have a ticket created for an uncaught exception (I am the co-founder of Bugsnag).

This might be optimal

public static string GetPropertyName<TResult>(Expression<Func<TResult>> expr)
{
    var memberAccess = expr.Body as MemberExpression;
    var propertyInfo = memberAccess?.Member as PropertyInfo;
    var propertyName = propertyInfo?.Name;

    return propertyName;
}

It seems like an IllegalArgumentException is called for if you don't want null to be an allowed value, and the NullPointerException would be thrown if you were trying to use a variable that turns out to be null.

You can access elements using $document ($document need to be injected)

var target = $document('#appBusyIndicator');
var target = $document('appBusyIndicator');

or with angular element, the specified elements can be accessed as:

var targets = angular.element(document).find('div'); //array of all div
var targets = angular.element(document).find('p');
var target = angular.element(document).find('#appBusyIndicator');

Use two periods before /, example:

../style.css

Take a look at this: slide ExpandableListView at DrawerLayout form right to left

I assume you have the ActionBarDrawerToggle implemented, the trick is to override the onOptionsItemSelected(MenuItem item) method inside the ActionBarDrawerToggle object with this:

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item != null && item.getItemId() == android.R.id.home) {
            if (mDrawer.isDrawerOpen(Gravity.RIGHT)) {
                mDrawer.closeDrawer(Gravity.RIGHT);
            } else {
                mDrawer.openDrawer(Gravity.RIGHT);
            }
            return true;
        }
        return false;
    }

make sure and call this from onOptionsItemSelected(MenuItem item) in the Activity:

@Override
public boolean onOptionsItemSelected(MenuItem item) {

if(mDrawerToggle.onOptionsItemSelected(item)) {
    return true;
}

return super.onOptionsItemSelected(item);
}

This will allow you to use the the home button functionality. To move the button to the right side of the action bar you will have to implement a custom action item, and maybe some other stuff to get it to work like you want.

I had the same issue. I think it would be appropriate to check whether your class can be compiled or not. Click recompile (Ctrl+Shift+F9 by default). If its not working then you have to investigate why it isn't compiling.

In my case the code wasn't autocompiling because there were hidden errors with compilation (they weren't shown in logs anywhere and maven clean-install was working). The rootcause was incorrect Project Structure -> Modules configuration, so Intellij Idea wasn't able to build it according to this configuration.
