While joshperry's answer is correct, I find very annoying that it does not tell you the screen name (the one you set with -t option), that is actually what you use to identify a session. (not his fault, of course, that's a screen's flaw)

That's why I instead use a script such as this: ps auxw|grep -i screen|grep -v grep

Here is dirty way:

1. Log into a linux server using "ssh -X user@host"
2. open rxvt-unicode or other X terminal.
3. open tmux or screen
4. Log back into your local computer from the server
5. start your favourite shell such as msys or cygwin.

As Already mentioned we have two ways!

 Per screen (session) interactive setting

And it's done interactively! And take effect immediately!

CTRL + A followed by : And we type scrollback 1000000 And hit ENTER

You detach from the screen and come back! It will be always the same.

You open another new screen! And the value is reset again to default! So it's not a global setting!

 And the permanent default setting

Which is done by adding defscrollback 1000000 to .screenrc (in home)

defscrollback and not scrollback (def stand for default)

What you need to know is if the file is not created ! You create it !

> cd ~ && vim .screenrc

And you add defscrollback 1000000 to it!

Or in one command

> echo "defscrollback 1000000" >> .screenrc

(if not created already)

Taking effect

When you add the default to .screenrc! The already running screen at re-attach will not take effect! The .screenrc run at the screen creation! And it make sense! Just as with a normal console and shell launch!

And all the new created screens will have the set value!

Checking the screen effective buffer size

To check type CTRL + A followed by i

And The result will be as

Importantly the buffer size is the number after the + sign
(in the illustration i set it to 1 000 000)

Note too that when you change it interactively! The effect is immediate and take over the default value!

Scrolling

CTRL+ A followed by ESC (to enter the copy mode).

Then navigate with Up,Down or PgUp PgDown

And ESC again to quit that mode.

(Extra info: to copy hit ENTER to start selecting! Then ENTER again to copy! Simple and cool)

Now the buffer is bigger!

And that's sum it up for the important details!

    pgrep -f process_name > any_file_name
    sed -i 's/^/kill /' any_file_name
    chmod 777 any_file_name
    ./any_file_name

for example 'pgrep -f firefox' will grep the PID of running 'firefox' and will save this PID to a file called 'any_file_name'. 'sed' command will add the 'kill' in the beginning of the PID number in 'any_file_name' file. Third line will make 'any_file_name' file executable. Now forth line will kill the PID available in the file 'any_file_name'. Writing the above four lines in a file and executing that file can do the control-C. Working absolutely fine for me.

== ISSUE THIS COMMAND
[xxx@devxxx ~]$ screen -ls


== SCREEN RESPONDS
There are screens on:
        23487.pts-0.devxxx      (Detached)
        26727.pts-0.devxxx      (Attached)
2 Sockets in /tmp/uscreens/S-xxx.


== NOW KILL THE ONE YOU DONT WANT
[xxx@devxxx ~]$ screen -X -S 23487.pts-0.devxxx kill


== WANT PROOF?
[xxx@devxxx ~]$ screen -ls
There is a screen on:
        26727.pts-0.devxxx      (Attached)
1 Socket in /tmp/uscreens/S-xxx.

To create a new screen with the name foo, use

screen -S foo

Then to reattach it, run

screen -r foo  # or use -x, as in
screen -x foo  # for "Multi display mode" (see the man page)

Ctrl+A then Shift+H works for me. You can view the file screenlog.0 while the program is still running.

try with screen -d -r or screen -D -RR

• Ctrl + A, Ctrl + \ - Exit screen and terminate all programs in this screen. It is helpful, for example, if you need to close a tty connection.

• Ctrl + D, D or - Ctrl + A, Ctrl + D - "minimize" screen and screen -r to restore it.

Create screen from Terminal:

screen -S <screen_name>

To see list of screens:

<screen -ls> or <screen -list>

To go to particular screen:

<screen -x screen_name>

<screen -r screen_name>

Inside screen

To Terminate screen:

give ctrl+d screen will get terminated

To Detach screen:

 give <ctrl+ad>or <screen -d >screen will get detached

To reattach screen:

screen -x <screen_name> or screen -r <screen_name>

To kill a screen from Terminal:

<screen -X -S screen_name quit> 

or

<screen -X -S screen_name kill>

You can use screen_name or process_id to execute commands.

Microsoft guidelines as checked by FxCop discourage use of List<T> in public APIs - prefer IList<T>.

Incidentally, I now almost always declare one-dimensional arrays as IList<T>, which means I can consistently use the IList<T>.Count property rather than Array.Length. For example:

public interface IMyApi
{
    IList<int> GetReadOnlyValues();
}

public class MyApiImplementation : IMyApi
{
    public IList<int> GetReadOnlyValues()
    {
        List<int> myList = new List<int>();
        ... populate list
        return myList.AsReadOnly();
    }
}
public class MyMockApiImplementationForUnitTests : IMyApi
{
    public IList<int> GetReadOnlyValues()
    {
        IList<int> testValues = new int[] { 1, 2, 3 };
        return testValues;
    }
}

Use SelectTab like this:

TabPage t = tabControl1.TabPages[2];
tabControl1.SelectTab(t); //go to tab

Use SelectedTab like this:

TabPage t = tabControl1.TabPages[2];
tabControl1.SelectedTab = t; //go to tab

JAVA_HOME should point to jdk directory and not to jre directory. Also JAVA_HOME should point to the home jdk directory and not to jdk/bin directory.

Assuming that you have JDK installed in your program files directory then you need to set the JAVA_HOME like this:

JAVA_HOME="C:\Program Files\Java\jdkxxx"

xxx is the jdk version

Follow this link to learn more about setting JAVA_HOME:

Since the question is about what is the fastest method, I thought I'd throw up add some perf metrics.

TL;DR The winner, by a wide margin, is the + operator, and please never use regex

https://jsperf.com/prepend-text-to-string/1

Open the file:

/Applications/NetBeans/NetBeans\ 8.0.2.app/Contents/Resources/NetBeans/etc/netbeans.conf

I added some options shown below:

netbeans_default_options="-J-Dsun.java2d.opengl=true -J-Dsun.java2d.d3d=false -J-Xmx2048m ...

Using opengl may help you, depending on your system. I am running OsX. 2048m may be too much, but does not seem to hurt :-) ...

It depends what is a use of those tables, but you might consider putting trigger on original table on insert and update. When insert or update is done, update the second table based on only one item from the original table. It will be quicker.

As another answer here stated:

pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U

Is a possible solution: Some comments here, myself included, had issues with permissions while using this command. A little change to the following solved those for me.

pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 sudo -H pip install -U

Note the added sudo -H which allowed the command to run with root permissions.

try this:

import time
import os

n = 0
for x in range(10): #enter your value here
    print(n)
    time.sleep(1) #to wait a second
    os.system('cls') #to clear previous number
                     #use ('clear') if you are using linux or mac!
    n = n + 1

Regardless to what is said above, on my ubuntu 16 i had to do :

> split -b 10M -d  system.log system_split.log 

Please note the space between -b and the value

My two cents:

I had a ton of problems trying to get my CUDA 8.0 installed properly on Windows 7. I had a previous version installed and I wanted to upgrade so I uninstalled it and tried to install CUDA 8.0 (for tensorflow 1.3). The installation failed every single time, I tried to downgrade to CUDA 7.5 and was able to install it but had a ton of problems with tensorflow (similar to the PATH problem described here). Long story short: what worked for me was:

1) Uninstall EVERY NVIDIA component (except the display graphics driver)

2) Download CUDA toolkit 8.0 (and the patch) https://developer.nvidia.com/cuda-downloads

3) Check the CheckSum MD5 (I used MS https://www.microsoft.com/en-ca/download/confirmation.aspx?id=11533 but any would do) to make sure they were OK (it happened several times that the installer was not dowloaded properly because my WiFi router apparently).

4) Run the CUDA toolkit installer as root

5) download the cudnn 8.0 v6 and add its location to the PATH variable https://developer.nvidia.com/rdp/cudnn-download

Hope that helps and saves some headaches...

NOTE: This script helped me a lot to debug the problem! (Thank you mrry) https://gist.github.com/mrry/ee5dbcfdd045fa48a27d56664411d41c

One refinement to some of these answers is to let CSS do more of the work.

The basic route seems to be:

1. Create a container element to hold the textarea and a hidden div
2. Using Javascript, keep the textarea’s contents synced with the div’s
3. Let the browser do the work of calculating the height of that div
4. Because the browser handles rendering / sizing the hidden div, we avoid explicitly setting the textarea’s height.

document.addEventListener('DOMContentLoaded', () => {_x000D_
    textArea.addEventListener('change', autosize, false)_x000D_
    textArea.addEventListener('keydown', autosize, false)_x000D_
    textArea.addEventListener('keyup', autosize, false)_x000D_
    autosize()_x000D_
}, false)_x000D_
_x000D_
function autosize() {_x000D_
    // Copy textarea contents to div browser will calculate correct height_x000D_
    // of copy, which will make overall container taller, which will make_x000D_
    // textarea taller._x000D_
    textCopy.innerHTML = textArea.value.replace(/\n/g, '<br/>')_x000D_
}

html, body, textarea {_x000D_
    font-family: sans-serif;_x000D_
    font-size: 14px;_x000D_
}_x000D_
_x000D_
.textarea-container {_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.textarea-container > div, .textarea-container > textarea {_x000D_
    word-wrap: break-word; /* make sure the div and the textarea wrap words in the same way */_x000D_
    box-sizing: border-box;_x000D_
    padding: 2px;_x000D_
    width: 100%;_x000D_
}_x000D_
_x000D_
.textarea-container > textarea {_x000D_
    overflow: hidden;_x000D_
    position: absolute;_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.textarea-container > div {_x000D_
    padding-bottom: 1.5em; /* A bit more than one additional line of text. */ _x000D_
    visibility: hidden;_x000D_
}

<div class="textarea-container">_x000D_
    <textarea id="textArea"></textarea>_x000D_

You should use

$this->db->where('$accommodation >=', minvalue);
$this->db->where('$accommodation <=', maxvalue);

I'm not sure of syntax, so I beg your pardon if it's not correct.
Anyway BETWEEN is implemented using >=min && <=max.
This is the meaning of my example.

EDITED:
Looking at this link I think you could write:

$this->db->where("$accommodation BETWEEN $minvalue AND $maxvalue");

• This solution uses csv-parser instead of csv-parse used in some of the answers above.
• csv-parser came around 2 years after csv-parse.
• Both of them solve the same purpose, but personally I have found csv-parser better, as it is easy to handle headers through it.

Install the csv-parser first:

npm install csv-parser

So suppose you have a csv-file like this:

NAME, AGE
Lionel Messi, 31
Andres Iniesta, 34

You can perform the required operation as:

const fs = require('fs'); 
const csv = require('csv-parser');

fs.createReadStream(inputFilePath)
.pipe(csv())
.on('data', function(data){
    try {
        console.log("Name is: "+data.NAME);
        console.log("Age is: "+data.AGE);

        //perform the operation
    }
    catch(err) {
        //error handler
    }
})
.on('end',function(){
    //some final operation
});

In your specific example you don't need to escape the equals - you only need to escape it if it's part of the key. The properties file format will treat all characters after the first unescaped equals as part of the value.

I think we should sent in this format

var array = [1, 2, 3, 4, 5];
$.post('/controller/MyAction', $.param({ data: array }, true), function(data) {});

Its already mentioned in Pass array to mvc Action via AJAX

It worked for me

You will need to install a local mailserver in order to do this. If you want to send it to external e-mail addresses, it might end up in unwanted e-mails or it may not arrive at all.

A good mailserver which I use (I use it on Linux, but it's also available for Windows) is Axigen: http://www.axigen.com/mail-server/download/

You might need some experience with mailservers to install it, but once it works, you can do anything you want with it.

The Entity Framework should not cause major bottlenecks itself. Chances are that there are other causes. You could try to switch EF to Linq2SQL, both have comparing features and the code should be easy to convert but in many cases Linq2SQL is faster than EF.

Please note Craig McDaniel's solution is clearly better.

logging.Formatter's formatTime method looks like this:

def formatTime(self, record, datefmt=None):
    ct = self.converter(record.created)
    if datefmt:
        s = time.strftime(datefmt, ct)
    else:
        t = time.strftime("%Y-%m-%d %H:%M:%S", ct)
        s = "%s,%03d" % (t, record.msecs)
    return s

Notice the comma in "%s,%03d". This can not be fixed by specifying a datefmt because ct is a time.struct_time and these objects do not record milliseconds.

If we change the definition of ct to make it a datetime object instead of a struct_time, then (at least with modern versions of Python) we can call ct.strftime and then we can use %f to format microseconds:

import logging
import datetime as dt

class MyFormatter(logging.Formatter):
    converter=dt.datetime.fromtimestamp
    def formatTime(self, record, datefmt=None):
        ct = self.converter(record.created)
        if datefmt:
            s = ct.strftime(datefmt)
        else:
            t = ct.strftime("%Y-%m-%d %H:%M:%S")
            s = "%s,%03d" % (t, record.msecs)
        return s

logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)

console = logging.StreamHandler()
logger.addHandler(console)

formatter = MyFormatter(fmt='%(asctime)s %(message)s',datefmt='%Y-%m-%d,%H:%M:%S.%f')
console.setFormatter(formatter)

logger.debug('Jackdaws love my big sphinx of quartz.')
# 2011-06-09,07:12:36.553554 Jackdaws love my big sphinx of quartz.

Or, to get milliseconds, change the comma to a decimal point, and omit the datefmt argument:

class MyFormatter(logging.Formatter):
    converter=dt.datetime.fromtimestamp
    def formatTime(self, record, datefmt=None):
        ct = self.converter(record.created)
        if datefmt:
            s = ct.strftime(datefmt)
        else:
            t = ct.strftime("%Y-%m-%d %H:%M:%S")
            s = "%s.%03d" % (t, record.msecs)
        return s

...
formatter = MyFormatter(fmt='%(asctime)s %(message)s')
...
logger.debug('Jackdaws love my big sphinx of quartz.')
# 2011-06-09 08:14:38.343 Jackdaws love my big sphinx of quartz.

I'd recommend application/octet-stream as RFC2046 says "The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data" and "The recommended action for an implementation that receives an "application/octet-stream" entity is to simply offer to put the data in a file[...]".

I think that way you will get better handling from arbitrary programs, that might barf when encountering your unknown mime type.

Set the CheckBox as focusable="false" in your XML layout. Otherwise it will steal click events from the list view.

Of course, if you do this, you need to manually handle marking the CheckBox as checked/unchecked if the list item is clicked instead of the CheckBox, but you probably want that anyway.

I have improved @dacoinminster answer and this is the result with an example to share your app:

// Intents with SEND action
PackageManager packageManager = context.getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(sendIntent, 0);

List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
Resources resources = context.getResources();

for (int j = 0; j < resolveInfoList.size(); j++) {
    ResolveInfo resolveInfo = resolveInfoList.get(j);
    String packageName = resolveInfo.activityInfo.packageName;
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_SEND);
    intent.setComponent(new ComponentName(packageName,
    resolveInfo.activityInfo.name));
    intent.setType("text/plain");

    if (packageName.contains("twitter")) {
        intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.twitter) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
    } else {
        // skip android mail and gmail to avoid adding to the list twice
        if (packageName.contains("android.email") || packageName.contains("android.gm")) {
            continue;
        }
        intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForFacebookWhatsapp) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
    }

    intentList.add(new LabeledIntent(intent, packageName, resolveInfo.loadLabel(packageManager), resolveInfo.icon));
}

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.subjectForMailApps));
emailIntent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForMailApps) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());

context.startActivity(Intent.createChooser(emailIntent, resources.getString(R.string.compartirEn)).putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new LabeledIntent[intentList.size()])));

First, you have to use System.IO namespace. Then;

string filename = @"C:\MyDirectory\MyFile.bat";
string newPath = Path.GetFullPath(fileName);

or

string newPath = Path.GetFullPath(openFileDialog1.FileName));

Find with a specific date:

db.getCollection('CollectionName').find({"DepartureDate" : new ISODate("2019-06-21T00:00:00.000Z")})

Find with greater gte or little lt :

db.getCollection('CollectionName').find({"DepartureDate" : { $gte : new ISODate("2019-06-11T00:00:00.000Z") }})

Find by range:

db.getCollection('CollectionName').find({ 
    "DepartureDate": { 
        $lt: new Date(), 
        $gte: new Date(new Date().setDate(new Date().getDate()-15))
      } 
    })

You can try this set unique attribute for each element

TextView mtextView = findViewById(R.id.myTextView);
mtextView.setShowSoftInputOnFocus(false);

Keyboard will not show while element is focus

Better way, with solution to tab and chrome problem and new jquery way

$("#element").on("focus keyup", function(e){

        var keycode = e.keyCode ? e.keyCode : e.which ? e.which : e.charCode;
        if(keycode === 9 || !keycode){
            // Hacemos select
            var $this = $(this);
            $this.select();

            // Para Chrome's que da problema
            $this.on("mouseup", function() {
                // Unbindeamos el mouseup
                $this.off("mouseup");
                return false;
            });
        }
    });

What I do is to call the N lines using pandas. I think the performance is not the best, but for example if N=1000:

import pandas as pd
yourfile = pd.read_csv('path/to/your/file.csv',nrows=1000)

set OPENSSL_CONF=c:/{path to openSSL}/bin/openssl.cfg

take care of the right extension (openssl.cfg not cnf)!

I have installed OpenSSL from here: http://slproweb.com/products/Win32OpenSSL.html

The only query bit I found that returns the EXACT same original number is

CONVERT (VARCHAR(50), float_field,128)

See http://www.connectsql.com/2011/04/normal-0-microsoftinternetexplorer4.html

The other solutions above will sometimes round or add digits at the end

UPDATE: As per comments below and what I can see in https://msdn.microsoft.com/en-us/library/ms187928.aspx:

CONVERT (VARCHAR(50), float_field,3)

Should be used in new SQL Server versions (Azure SQL Database, and starting in SQL Server 2016 RC3)

I'm sure you know that a std::vector<X> stores a whole bunch of X objects, right? But if you have a std::map<X, Y>, what it actually stores is a whole bunch of std::pair<const X, Y>s. That's exactly what a map is - it pairs together the keys and the associated values.

When you iterate over a std::map, you're iterating over all of these std::pairs. When you dereference one of these iterators, you get a std::pair containing the key and its associated value.

std::map<std::string, int> m = /* fill it */;
auto it = m.begin();

Here, if you now do *it, you will get the the std::pair for the first element in the map.

Now the type std::pair gives you access to its elements through two members: first and second. So if you have a std::pair<X, Y> called p, p.first is an X object and p.second is a Y object.

So now you know that dereferencing a std::map iterator gives you a std::pair, you can then access its elements with first and second. For example, (*it).first will give you the key and (*it).second will give you the value. These are equivalent to it->first and it->second.

While Docker for Windows is perfectly able to run Linux containers, the converse, while theoretically possible, is not implemented due to practical reasons.

The most obvious one is, while Docker for Windows can run a Linux VM freely, Docker for Linux would require a Windows license in order to run it inside a VM.

Also, Linux is completely customizable, so the Linux VM used by Docker for Windows has been stripped down to just a few MB, containing only the bare minimum needed to run the containers, while the smallest Windows distribution available is about 1.5 GB. It may not be an impracticable size, but it is much more cumbersome than the Linux on Windows counterpart.

While it is certainly possible for someone to sell a Docker for Linux variation bundled with a Windows license and ready to run Windows containers under Linux (and I don't know if such product exists), the bottom line is that you can't avoid paying Windows vendor lock-in price: both in money and storage space.

You may take a look at intellij code folding shortcuts.

For Windows/Linux do: Ctrl+Shift+-

For mac use Command+Shift+-

To unfold again do Ctrl+Shift++ or Command+Shift++ respectivley.

Yes you can do it using the JsonConvert.DeserializeObject. To do that, just simple do:

dynamic jsonResponse = JsonConvert.DeserializeObject(json);
Console.WriteLine(jsonResponse["message"]);

Hash === @some_var #=> return Boolean

this can also be used with case statement

case @some_var
when Hash
   ...
when Array
   ...
end

I was facing the same issue then i made my key 16 byte and it's working properly now. Create your key exactly 16 byte. It will surely work.

Watch out for case sensitivity. If you have a file

/Content/bootstrap.css

and you redirect in your Bundle.config to

.Include("~/Content/Bootstrap.css")

it will not load the css.

The easiest way would be to create a new (simple) Maven project using the "new project" wizard. You can then migrate your source into the Maven folder structure + the auto generated POM file.

Lambda Expressions

To add on to jk.'s excellent answer, you can now pass a method more easily using Lambda Expressions (in Java 8). First, some background. A functional interface is an interface that has one and only one abstract method, although it can contain any number of default methods (new in Java 8) and static methods. A lambda expression can quickly implement the abstract method, without all the unnecessary syntax needed if you don't use a lambda expression.

Without lambda expressions:

obj.aMethod(new AFunctionalInterface() {
    @Override
    public boolean anotherMethod(int i)
    {
        return i == 982
    }
});

With lambda expressions:

obj.aMethod(i -> i == 982);

Here is an excerpt from the Java tutorial on Lambda Expressions:

Syntax of Lambda Expressions

A lambda expression consists of the following:

• A comma-separated list of formal parameters enclosed in parentheses. The CheckPerson.test method contains one parameter, p, which represents an instance of the Person class.
  
  Note: You can omit the data type of the parameters in a lambda expression. In addition, you can omit the parentheses if there is only one parameter. For example, the following lambda expression is also valid:

  p -> p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

• The arrow token, ->

• A body, which consists of a single expression or a statement block. This example uses the following expression:

  p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

  If you specify a single expression, then the Java runtime evaluates the expression and then returns its value. Alternatively, you can use a return statement:

  p -> {
      return p.getGender() == Person.Sex.MALE
          && p.getAge() >= 18
          && p.getAge() <= 25;
  }
  

  A return statement is not an expression; in a lambda expression, you must enclose statements in braces ({}). However, you do not have to enclose a void method invocation in braces. For example, the following is a valid lambda expression:

  email -> System.out.println(email)
  

Note that a lambda expression looks a lot like a method declaration; you can consider lambda expressions as anonymous methods—methods without a name.

Here is how you can "pass a method" using a lambda expression:

^{Note: this uses a new standard functional interface, java.util.function.IntConsumer.}

class A {
    public static void methodToPass(int i) { 
        // do stuff
    }
}

import java.util.function.IntConsumer;

class B {
    public void dansMethod(int i, IntConsumer aMethod) {
        /* you can now call the passed method by saying aMethod.accept(i), and it
        will be the equivalent of saying A.methodToPass(i) */
    }
}

class C {
    B b = new B();

    public C() {
        b.dansMethod(100, j -> A.methodToPass(j));   //Lambda Expression here
    }
}

The above example can be shortened even more using the :: operator.

public C() {
    b.dansMethod(100, A::methodToPass);
}

This is an extension to Cezary's answer. If you want to download it to a specific directory, use this. Also, use const instead of var. Its safe this way.

const fs = require('fs');
const request = require('request');
var download = function(uri, filename, callback){
  request.head(uri, function(err, res, body){    
    request(uri).pipe(fs.createWriteStream(filename)).on('close', callback);
  });
};

download('https://www.google.com/images/srpr/logo3w.png', './images/google.png', function(){
  console.log('done');
});

Maybe you can use a helper function like this:

// events and args should be of type Array
function addMultipleListeners(element,events,handler,useCapture,args){
  if (!(events instanceof Array)){
    throw 'addMultipleListeners: '+
          'please supply an array of eventstrings '+
          '(like ["click","mouseover"])';
  }
  //create a wrapper to be able to use additional arguments
  var handlerFn = function(e){
    handler.apply(this, args && args instanceof Array ? args : []);
  }
  for (var i=0;i<events.length;i+=1){
    element.addEventListener(events[i],handlerFn,useCapture);
  }
}

function handler(e) {
  // do things
};

// usage
addMultipleListeners(
    document.getElementById('first'),
    ['touchstart','click'],
    handler,
    false);

[Edit nov. 2020] This answer is pretty old. The way I solve this nowadays is by using an actions object where handlers are specified per event type, a data-attribute for an element to indicate which action should be executed on it and one generic document wide handler method (so event delegation).

const firstElemHandler = (elem, evt) =>
  elem.textContent = `You ${evt.type === "click" ? "clicked" : "touched"}!`;
const actions = {
  click: {
    firstElemHandler,
  },
  touchstart: {
    firstElemHandler,
  },
  mouseover: {
    firstElemHandler: elem => elem.textContent = "Now ... click me!",
    outerHandling: elem => {
      console.clear();
      console.log(`Hi from outerHandling, handle time ${
        new Date().toLocaleTimeString()}`);
    },
  }
};

Object.keys(actions).forEach(key => document.addEventListener(key, handle));

function handle(evt) {
  const origin = evt.target.closest("[data-action]");
  return origin &&
    actions[evt.type] &&
    actions[evt.type][origin.dataset.action] &&
    actions[evt.type][origin.dataset.action](origin, evt) ||
    true;
}

[data-action]:hover {
  cursor: pointer;
}

<div data-action="outerHandling">
  <div id="first" data-action="firstElemHandler">
    <b>Hover, click or tap</b>
  </div>
  this is handled too (on mouse over)
</div>

Simply type the following command on the command line inside the virtual environment:

deactivate

It turns out I didn't have Microsoft visual c++ installed, installing it solved the problem for me.

I have found one related behaviour that may help (sounds like your specific problem runs deeper though):

Flash checks whether a source file needs recompiling by looking at timestamps. If its compiled version is older than the source file, it will recompile. But it doesn't check whether the compiled version was generated from the same source file or not.

Specifically, if you have your actionscript files under version control, and you Revert a change, the reverted file will usually have an older timestamp, and Flash will ignore it.

Alternative solution can be to remove the rows with blanks in one variable:

df <- subset(df, VAR != "")

I think the following will achieve what you are after

function func( orig, target ) {

    var i = orig.length, j = 0, total = 0, change, newVals = [], next, factor1, factor2, len = orig.length, marginOfErrors = [];

    // map original values to new array
    while( i-- ) {
        total += newVals[i] = Math.round( orig[i] );
    }

    change = total < target ? 1 : -1;

    while( total !== target ) {

        // Iterate through values and select the one that once changed will introduce
        // the least margin of error in terms of itself. e.g. Incrementing 10 by 1
        // would mean an error of 10% in relation to the value itself.
        for( i = 0; i < len; i++ ) {

            next = i === len - 1 ? 0 : i + 1;

            factor2 = errorFactor( orig[next], newVals[next] + change );
            factor1 = errorFactor( orig[i], newVals[i] + change );

            if(  factor1 > factor2 ) {
                j = next; 
            }
        }

        newVals[j] += change;
        total += change;
    }


    for( i = 0; i < len; i++ ) { marginOfErrors[i] = newVals[i] && Math.abs( orig[i] - newVals[i] ) / orig[i]; }

    // Math.round() causes some problems as it is difficult to know at the beginning
    // whether numbers should have been rounded up or down to reduce total margin of error. 
    // This section of code increments and decrements values by 1 to find the number
    // combination with least margin of error.
    for( i = 0; i < len; i++ ) {
        for( j = 0; j < len; j++ ) {
            if( j === i ) continue;

            var roundUpFactor = errorFactor( orig[i], newVals[i] + 1)  + errorFactor( orig[j], newVals[j] - 1 );
            var roundDownFactor = errorFactor( orig[i], newVals[i] - 1) + errorFactor( orig[j], newVals[j] + 1 );
            var sumMargin = marginOfErrors[i] + marginOfErrors[j];

            if( roundUpFactor < sumMargin) { 
                newVals[i] = newVals[i] + 1;
                newVals[j] = newVals[j] - 1;
                marginOfErrors[i] = newVals[i] && Math.abs( orig[i] - newVals[i] ) / orig[i];
                marginOfErrors[j] = newVals[j] && Math.abs( orig[j] - newVals[j] ) / orig[j];
            }

            if( roundDownFactor < sumMargin ) { 
                newVals[i] = newVals[i] - 1;
                newVals[j] = newVals[j] + 1;
                marginOfErrors[i] = newVals[i] && Math.abs( orig[i] - newVals[i] ) / orig[i];
                marginOfErrors[j] = newVals[j] && Math.abs( orig[j] - newVals[j] ) / orig[j];
            }

        }
    }

    function errorFactor( oldNum, newNum ) {
        return Math.abs( oldNum - newNum ) / oldNum;
    }

    return newVals;
}


func([16.666, 16.666, 16.666, 16.666, 16.666, 16.666], 100); // => [16, 16, 17, 17, 17, 17]
func([33.333, 33.333, 33.333], 100); // => [34, 33, 33]
func([33.3, 33.3, 33.3, 0.1], 100); // => [34, 33, 33, 0] 
func([13.25, 47.25, 11.25, 28.25], 100 ); // => [13, 48, 11, 28]
func( [25.5, 25.5, 25.5, 23.5], 100 ); // => [25, 25, 26, 24]

One last thing, I ran the function using the numbers originally given in the question to compare to the desired output

func([13.626332, 47.989636, 9.596008, 28.788024], 100); // => [48, 29, 13, 10]

This was different to what the question wanted => [ 48, 29, 14, 9]. I couldn't understand this until I looked at the total margin of error

-------------------------------------------------
| original  | question | % diff | mine | % diff |
-------------------------------------------------
| 13.626332 | 14       | 2.74%  | 13   | 4.5%   |
| 47.989636 | 48       | 0.02%  | 48   | 0.02%  |
| 9.596008  | 9        | 6.2%   | 10   | 4.2%   |
| 28.788024 | 29       | 0.7%   | 29   | 0.7%   |
-------------------------------------------------
| Totals    | 100      | 9.66%  | 100  | 9.43%  |
-------------------------------------------------

Essentially, the result from my function actually introduces the least amount of error.

Fiddle here

You can check if you got your remote setup right and have the proper permissions with

git ls-remote origin

if you called your remote "origin". If you get an error you probably don't have your security set up correctly such as uploading your public key to github for example. If things are setup correctly, you will get a list of the remote references. Now

git fetch origin

will work barring any other issues like an unplugged network cable.

Once you have that done, you can get any branch you want that the above command listed with

git checkout some-branch

this will create a local branch of the same name as the remote branch and check it out.

As I understand, if have id's: 1,2,4,5 it should return 3.

SELECT t1.id + 1
FROM theTable t1
WHERE NOT EXISTS (
    SELECT * 
    FROM theTable t2
    WHERE t2.id = t1.id + 1
)
LIMIT 1

for me best solotion this is

 Thread.CurrentThread.Abort();

and force close app.

In fact, you need to use CSS.

document.getElementById("myDivId").setAttribute("style","opacity:0.5; -moz-opacity:0.5; filter:alpha(opacity=50)");

It works on FireFox, Chrome and IE.

Java 8

stringCollection.stream().collect(Collectors.joining(", "));

As per my understanding you want data in dictionary as shown below:

key1: value1-1,value1-2,value1-3....value100-1
key2: value2-1,value2-2,value2-3....value100-2
key3: value3-1,value3-2,value3-2....value100-3

for this you can use list for each dictionary keys:

case_list = {}
for entry in entries_list:
    if key in case_list:
        case_list[key1].append(value)
    else:
        case_list[key1] = [value]

You can just delete .git. Typically:

rm -rf .git

Then, recreate as the right user.

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

even there is no right or wrong answer for this question , but I personally prefer 960px width . since all modern monitors support at least 1024 × 768 pixel resolution. 960 is divisible by 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320 and 480. This makes it a highly flexible base number to work with.

You can do this easily by Modifying Response Headers which can be done with Chrome and Firefox extension like Requestly.

In Chrome and Firefox:

1. Install Requestly for Chrome and Requestly for Firefox

2. Add the following Headers Modification Rules:

   

   a) Content-Type:

   • Modify
   • Response
   • Header: Content-Type
   • Value: text/html
   • Source Url Matches: /raw\.githubusercontent\.com/.*\.html/

   
   

   b) Content-Security-Policy:

   • Modify
   • Response
   • Header: Content-Security-Policy
   • Value: default-src 'none'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; script-src * 'unsafe-eval';
   • Source Url Matches: /raw\.githubusercontent\.com/.*\.html/

Use the pow(x,y) function: See Here

Just include math.h and you're all set.

You need to print to get that output.
You should do

>>> x = "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])
>>> x                   # this is the value, returned by the join() function
'I\nwould\nexpect\nmultiple\nlines'
>>> print x    # this prints your string (the type of output you want)
I
would
expect
multiple
lines

As of version 0.8.9, Android Studio supports the Maven Central Repository by default. So to add an external maven dependency all you need to do is edit the module's build.gradle file and insert a line into the dependencies section like this:

dependencies {

    // Remote binary dependency
    compile 'net.schmizz:sshj:0.10.0'

}

You will see a message appear like 'Sync now...' - click it and wait for the maven repo to be downloaded along with all of its dependencies. There will be some messages in the status bar at the bottom telling you what's happening regarding the download. After it finishes this, the imported JAR file along with its dependencies will be listed in the External Repositories tree in the Project Browser window, as shown below.

A div is a block level element, meaning that will behave as a block, and blocks can't stay side by side without being floated. You can however set them to inline elements with:

display:inline-block;

Give it a try...

Another way is to place them using:

position:absolute;
left:0;

and/or

position:absolute;
right:0;

Note: For this to work as expected, the wrapper element must have a position:relative; so that the elements with absolute positioning stay relative to their wrapper element.

            <fo:block/>
            <xsl:value-of select="OU_COUNTRY"/>

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

Don't forget the padding and margins...

jQuery.fn.slideLeftHide = function(speed, callback) { 
  this.animate({ 
    width: "hide", 
    paddingLeft: "hide", 
    paddingRight: "hide", 
    marginLeft: "hide", 
    marginRight: "hide" 
  }, speed, callback);
}

jQuery.fn.slideLeftShow = function(speed, callback) { 
  this.animate({ 
    width: "show", 
    paddingLeft: "show", 
    paddingRight: "show", 
    marginLeft: "show", 
    marginRight: "show" 
  }, speed, callback);
}

With the speed/callback arguments added, it's a complete drop-in replacement for slideUp() and slideDown().

DOUBLE columns are not the same as DECIMAL columns, and you will get in trouble if you use DOUBLE columns for financial data.

DOUBLE is actually just a double precision (64 bit instead of 32 bit) version of FLOAT. Floating point numbers are approximate representations of real numbers and they are not exact. In fact, simple numbers like 0.01 do not have an exact representation in FLOAT or DOUBLE types.

DECIMAL columns are exact representations, but they take up a lot more space for a much smaller range of possible numbers. To create a column capable of holding values from 0.0001 to 99.9999 like you asked you would need the following statement

CREATE TABLE your_table
(
    your_column DECIMAL(6,4) NOT NULL
);

The column definition follows the format DECIMAL(M, D) where M is the maximum number of digits (the precision) and D is the number of digits to the right of the decimal point (the scale).

This means that the previous command creates a column that accepts values from -99.9999 to 99.9999. You may also create an UNSIGNED DECIMAL column, ranging from 0.0000 to 99.9999.

For more information on MySQL DECIMAL the official docs are always a great resource.

Bear in mind that all of this information is true for versions of MySQL 5.0.3 and greater. If you are using previous versions, you really should upgrade.

In case anyone else has come here looking for an answer to this question, there's a Windows API function called GetProcessTimes(). It doesn't look like too much work to write a little C program that would start the command, make this call, and return the process times.

Try adding

ngModel in module level

The code is same as the above

Boolean(val) === false. This worked for me to check if value was falsely.

just take the string and use the JavaScriptSerializer to deserialize it into a native object. For example, having this json:

string json = "[{Name:'John Simith',Age:35},{Name:'Pablo Perez',Age:34}]"; 

You'd need to create a C# class called, for example, Person defined as so:

public class Person
{
 public int Age {get;set;}
 public string Name {get;set;}
}

You can now deserialize the JSON string into an array of Person by doing:

JavaScriptSerializer js = new JavaScriptSerializer();
Person [] persons =  js.Deserialize<Person[]>(json);

Here's a link to JavaScriptSerializer documentation.

Note: my code above was not tested but that's the idea Tested it. Unless you are doing something "exotic", you should be fine using the JavascriptSerializer.

Type in command line :

$ export http_proxy=http://proxy_host:proxy_port

for authenticated proxy,

$ export http_proxy=http://username:password@proxy_host:proxy_port

and then run

$ wget fileurl

for https, just use https_proxy instead of http_proxy. You could also put these lines in your ~/.bashrc file so that you don't need to execute this everytime.

If you don't know how to enable php_mbstring extension in windows, open your php.ini and remove the semicolon before the extension:

change this

;extension=php_mbstring.dll

to this

extension=php_mbstring.dll

after modification, you need to reset your php server.

If you truly wish to use PHP, you could use

include "file.php";

or

require "file.php";

and then in file.php, use a heredoc & echo it in.

file.php contents:
$some_js_code <<<_code
function myFunction()
{
   Alert("Some JS code would go here.");
}
_code;

At the top of your PHP file, bring in the file using either include or require then in head (or body section) echo it in

<?php
require "file.php";
?>
<html>
<head>
<?php
echo $some_js_code;
?>
</script>
</head>
<body>
</body>
</html>

Different way but it works. Just my $.02...

Use List<T>.Insert

While not relevant to your specific example, if performance is important also consider using LinkedList<T> because inserting an item to the start of a List<T> requires all items to be moved over. See When should I use a List vs a LinkedList.

To get parent window handles.

String parentHandle = driverObj.getWindowHandle();
public String switchTab(String parentHandle){
    String currentHandle ="";
    Set<String> win  = ts.getDriver().getWindowHandles();   

    Iterator<String> it =  win.iterator();
    if(win.size() > 1){
        while(it.hasNext()){
            String handle = it.next();
            if (!handle.equalsIgnoreCase(parentHandle)){
                ts.getDriver().switchTo().window(handle);
                currentHandle = handle;
            }
        }
    }
    else{
        System.out.println("Unable to switch");
    }
    return currentHandle;
}

You can use Coil library to load svg. Just add these lines in build.gradle

// ... Coil (https://github.com/coil-kt/coil)
implementation("io.coil-kt:coil:0.12.0")
implementation("io.coil-kt:coil-svg:0.12.0")

Then Add an extension function

fun AppCompatImageView.loadSvg(url: String) {
    val imageLoader = ImageLoader.Builder(this.context)
        .componentRegistry { add(SvgDecoder([email protected])) }
        .build()

    val request = ImageRequest.Builder(this.context)
        .crossfade(true)
        .crossfade(500)
        .data(url)
        .target(this)
        .build()

    imageLoader.enqueue(request)
}

Then call this method in your activity or fragment

your_image_view.loadSvg("your_file_name.svg")

After about seven years, here's a more elegant answer using collections.deque:

def ngrams(words, n):
    d = collections.deque(maxlen=n)
    d.extend(words[:n])
    words = words[n:]
    for window, word in zip(itertools.cycle((d,)), words):
        print(' '.join(window))
        d.append(word)

words = ['I', 'am', 'become', 'death,', 'the', 'destroyer', 'of', 'worlds']

Output:

You could always write out the list of keys in addition to dumping the dict, and then reconstruct the OrderedDict by iterating through the list?

Here is something that i have been trying.(Insertion sort- not the best way to sort but does the work)

def sort(list):
    for index in range(1,len(list)):
        value = list[index]
        i = index-1
        while i>=0:
            if value < list[i]:
                list[i+1] = list[i]
                list[i] = value
                i -= 1
            else:
                break

You must just put the values into parentheses:

'%s in %s' % (unicode(self.author),  unicode(self.publication))

Here, for the first %s the unicode(self.author) will be placed. And for the second %s, the unicode(self.publication) will be used.

Note: You should favor string formatting over the % Notation. More info here

You can think of these as the opposites of one another.

When you free an area of memory, but still keep a pointer to it, that pointer is dangling:

char *c = malloc(16);
free(c);
c[1] = 'a'; //invalid access through dangling pointer!

When you lose the pointer, but keep the memory allocated, you have a memory leak:

void myfunc()
{
    char *c = malloc(16);
} //after myfunc returns, the the memory pointed to by c is not freed: leak!

I use Butterknife with switch-case to handle this kind of cases:

    @OnClick({R.id.button_bireysel, R.id.button_kurumsal})
        public void onViewClicked(View view) {
            switch (view.getId()) {


                case R.id.button_bireysel:
 //Do something

                    break;
                case R.id.button_kurumsal:

     //Do something

                    break;

            }
        }

But the thing is there is no default case and switch statement falls through

I ended up adding the following method to jQuery in my script:

jQuery["postJSON"] = function( url, data, callback ) {
    // shift arguments if data argument was omitted
    if ( jQuery.isFunction( data ) ) {
        callback = data;
        data = undefined;
    }

    return jQuery.ajax({
        url: url,
        type: "POST",
        contentType:"application/json; charset=utf-8",
        dataType: "json",
        data: data,
        success: callback
    });
};

And to use it

$.postJSON('http://url', {data: 'goes', here: 'yey'}, function (data, status, xhr) {
    alert('Nailed it!')
});

This was done by simply copying the code of "get" and "post" from the original JQuery sources and hardcoding a few parameters to force a JSON POST.

Thanks!

To define about event in simple way:

Event is a REFERENCE to a delegate with two restrictions

1. Cannot be invoked directly
2. Cannot be assigned values directly (e.g eventObj = delegateMethod)

Above two are the weak points for delegates and it is addressed in event. Complete code sample to show the difference in fiddler is here https://dotnetfiddle.net/5iR3fB .

Toggle the comment between Event and Delegate and client code that invokes/assign values to delegate to understand the difference

Here is the inline code.

 /*
This is working program in Visual Studio.  It is not running in fiddler because of infinite loop in code.
This code demonstrates the difference between event and delegate
        Event is an delegate reference with two restrictions for increased protection

            1. Cannot be invoked directly
            2. Cannot assign value to delegate reference directly

Toggle between Event vs Delegate in the code by commenting/un commenting the relevant lines

This is Andy's solution. I just addressed User2357112's concern and gave it meaningful variable names. I'm a Python rookie and preferred these functions.

def left(aString, howMany):
    if howMany <1:
        return ''
    else:
        return aString[:howMany]

def right(aString, howMany):
    if howMany <1:
        return ''
    else:
        return aString[-howMany:]

def mid(aString, startChar, howMany):
    if howMany < 1:
        return ''
    else:
        return aString[startChar:startChar+howMany]

An easy way to login with a HTTP POST without doing any Base64 specific calls is to use the HTTPClient BasicCredentialsProvider

import java.io.IOException;
import static java.lang.System.out;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.HttpClientBuilder;

//code
CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(user, password);
provider.setCredentials(AuthScope.ANY, credentials);
HttpClient client = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build();

HttpResponse response = client.execute(new HttpPost("http://address/test/login"));//Replace HttpPost with HttpGet if you need to perform a GET to login
int statusCode = response.getStatusLine().getStatusCode();
out.println("Response Code :"+ statusCode);

In case others may find this useful: I found that by adding an initial empty cell to my list of search terms, a zero value will be returned instead of error.

={INDEX(SearchTerms!$A$1:$A$38,MAX(IF(ISERROR(SEARCH(SearchTerms!$A$1:$A$38,SearchCell)),0,1)*((SearchTerms!$B$1:$B$38)+1)))}

NB: Column A has the search terms, B is the row number index.

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

You can also use another built-in template default_if_none

{{ profile.user.first_name|default_if_none:"--" }}

To answer a little more conceptually:

SelectedValuePath defines which property (by its name) of the objects bound to the ListBox's ItemsSource will be used as the item's SelectedValue.

For example, if your ListBox is bound to a collection of Person objects, each of which has Name, Age, and Gender properties, SelectedValuePath=Name will cause the value of the selected Person's Name property to be returned in SelectedValue.

Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, SelectedValuePath cannot be used.

SelectedItem, meanwhile, returns the entire Person object currently selected.

(Here's a further example from MSDN, using TreeView)

Update: As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:

Note that these values are distinct from DisplayMemberPath (which is defined on ItemsControl, not Selector), but that property has similar behavior to SelectedValuePath: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.

For 19.1 above on Linux,

Close the App or any window of Smartgit

Go to:

/home/[USERNAME]/.config/smartgit/[CURRENT OR LAST VERSION]

open the file:

preferences.yml

Search for:

"listx: {" in this file

You will find something like this:

listx: {ePP: 1607503071922, eUT: -9223377036854775808, nRT: -9223377036854775808, eV: '20.1', uid: emobf7q63s83}

So now all you need is delete the string inside the {} So it will be like this:

listx: {}

Now save the file and start Smartgit. You will have all repositories and other preferences and you will be asked for set the type of license.

add JAVA_HOME to the file:

/etc/environment

for it to be available to the entire system (you would need to restart Ubuntu though)

Lea's converter is no longer available. I just used this converter

Steps:

1. Enter the Unicode decimal version such as 8226 in the tool's green input field.
2. Press Dec code points
3. See the result in the box Unicode U+hex notation (eg U+2022)

Using com.ibm.etools.marshall.util.BigDecimalRange util class of IBM one can compare if BigDecimal in range.

boolean isCalculatedSumInRange = BigDecimalRange.isInRange(low, high, calculatedSum);

This is a warning for usual. You can either disable it by

#pragma warning(disable:4996)

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

Short answer: No practical, performance, or storage, difference.

Long answer:

There is essentially no difference (in MySQL) between VARCHAR(3000) (or any other large limit) and TEXT. The former will truncate at 3000 characters; the latter will truncate at 65535 bytes. (I make a distinction between bytes and characters because a character can take multiple bytes.)

For smaller limits in VARCHAR, there are some advantages over TEXT.

• "smaller" means 191, 255, 512, 767, or 3072, etc, depending on version, context, and CHARACTER SET.
• INDEXes are limited in how big a column can be indexed. (767 or 3072 bytes; this is version and settings dependent)
• Intermediate tables created by complex SELECTs are handled in two different ways -- MEMORY (faster) or MyISAM (slower). When 'large' columns are involved, the slower technique is automatically picked. (Significant changes coming in version 8.0; so this bullet item is subject to change.)
• Related to the previous item, all TEXT datatypes (as opposed to VARCHAR) jump straight to MyISAM. That is, TINYTEXT is automatically worse for generated temp tables than the equivalent VARCHAR. (But this takes the discussion in a third direction!)
• VARBINARY is like VARCHAR; BLOB is like TEXT.

Rebuttal to other answers

The original question asked one thing (which datatype to use); the accepted answer answered something else (off-record storage). That answer is now out of date.

When this thread was started and answered, there were only two "row formats" in InnoDB. Soon afterwards, two more formats (DYNAMIC and COMPRESSED) were introduced.

The storage location for TEXT and VARCHAR() is based on size, not on name of datatype. For an updated discussion of on/off-record storage of large text/blob columns, see this .

In JPA 2.1 you need to do the following

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Index;
import javax.persistence.Table;

@Entity(name="TEST_PERSON")
@Table(
    name="TEST_PERSON", 
    indexes = {
       @Index(name = "PERSON_INDX_0", columnList = "age"),
       @Index(name = "PERSON_INDX_1", columnList = "fName"),
       @Index(name = "PERSON_INDX_1", columnList = "sName")  })
public class TestPerson {

    @Column(name = "age", nullable = false)
    private int age;

    @Column(name = "fName", nullable = false)
    private String firstName;

    @Column(name = "sName", nullable = false)
    private String secondName;

    @Id
    private long id;

    public TestPerson() {
    }
}

In the above example the table TEST_PERSON will have 3 indexes:

• unique index on the primary key ID

• index on AGE

• compound index on FNAME, SNAME

Note 1: You get the compound index by having two @Index annotations with the same name

Note 2: You specify the column name in the columnList not the fieldName

It seems that the version "20140702" of the example link in the question was the final version, because I downloaded this file on the 12th November 2014, i.e. the version from the 2nd of July 2014 was still the latest version on 12th of November. When I try manually all the possible versions/dates between today in this date, then I always get a page with error code "404" (file not found), which indicates that no new version was released since the 12th of November.

<head>
    <script type="text/javascript">
        function SetMaxLength () {
            var input = document.getElementById("myInput");
            input.maxLength = 10;
        }
    </script>
</head>
<body>
    <input id="myInput" type="text" size="20" />

I had the same issue on linux, but I couldn't fix it with the accepted answer. I was able to solve it by using cd to go to the correct folder and then executing:

svn remove --force filename  
syn resolve --accept=working filename  
svn up

That's all.

its solved. Use nuget and search for the "ODP.NET, Managed Driver" invariant="Oracle.ManagedDataAccess.Client".

and install the package. it will resolve the issue for me.

You can't influence neither type (tab/window) nor dimensions that way. You'll have to use JavaScript's window.open() for that.

If you already have axes object, just like in Nick T's answer, you can also use

 ax.patch.set_facecolor('black')

An issue that DO arise in practical Android code is that comparing them with CharSequence.equals is valid but does not necessarily work as intended.

EditText t = (EditText )getView(R.id.myEditText); // Contains "OK"
Boolean isFalse = t.getText().equals("OK"); // will always return false.

Comparison should be made by

("OK").contentEquals(t.GetText()); 

I'm using Sublime portable version (for Windows) and this (placing the mousemap in SublimeText\Packages\User folder) did not work for me.

I had to place the mousemap file in SublimeText\Data\Packages\User folder to get it to work where SublimeText is the installation directory for my portable version. Data\Packages\User is where I found the keymap file as well.

You can set your data-type as signed integer. When you storage coordinates to SQL you can set as lat*10000000 and long*10000000. And when you selecting with distance/radius you will divide storage coordinates to 10000000. I was test it with 300K rows, query response time is good. ( 2 x 2.67GHz CPU, 2 GB RAM, MySQL 5.5.49 )

If you want to reverse the array in-place:

Collections.reverse(Arrays.asList(array));

It works since Arrays.asList returns a write-through proxy to the original array.

You could go into the designer of the web form and change the "webcontrols" to be "public" instead of "protected" but I'm not sure how safe that is. I prefer to make hidden inputs and have some jQuery set the values into those hidden inputs, then create public properties in the web form's class (code behind), and access the values that way.

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

Afterall, you could edit the .vimrc,then add the conf

set tabstop=4

Or exec the command

If you just want the button to have different styling while the mouse is pressed you can use the :active pseudo class.

.button:active {
}

If on the other hand you want the style to stay after clicking you will have to use javascript.

You can use the begin and end functions from the Boost range library to easily find the ends of a primitive array, and unlike the macro solution, this will give a compile error instead of broken behaviour if you accidentally apply it to a pointer.

const char* array[] = { "cat", "dog", "horse" };
vector<string> vec(begin(array), end(array));

The data is stored on the device, in your application's private data area. It is not in an Eclipse project.

In XML a line break is a normal character. You can do this:

<xml>
  <text>some text
with
three lines</text>
</xml>

and the contents of <text> will be

some text
with
three lines

If this does not work for you, you are doing something wrong. Special "workarounds" like encoding the line break are unnecessary. Stuff like \n won't work, on the other hand, because XML has no escape sequences^*.

^* Note that 
 is the character entity that represents a line break in serialized XML. "XML has no escape sequences" means the situation when you interact with a DOM document, setting node values through the DOM API.

This is where neither 
 nor things like \n will work, but an actual newline character will. How this character ends up in the serialized document (i.e. "file") is up to the API and should not concern you.

Since you seem to wonder where your line breaks go in HTML: Take a look into your source code, there they are. HTML ignores line breaks in source code. Use <br> tags to force line breaks on screen.

Here is a JavaScript function that inserts <br> into a multi-line string:

function nl2br(s) { return s.split(/\r?\n/).join("<br>"); }

Alternatively you can force line breaks at new line characters with CSS:

div.lines {
    white-space: pre-line;
}

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

Try this

$("#message span").text("hello world!");

function Errormessage(txt) {
    var elem = $("#message");
    elem.fadeIn("slow");
    // find the span inside the div and assign a text
    elem.children("span").text("your text");

    elem.children("a.close-notify").click(function() {
        elem.fadeOut("slow");
    });
}

Simulating a mouse click

My guess is that the webpage is listening to mousedown rather than click (which is bad for accessibility because when a user uses the keyboard, only focus and click are fired, not mousedown). So you should simulate mousedown, click, and mouseup (which, by the way, is what the iPhone, iPod Touch, and iPad do on tap events).

To simulate the mouse events, you can use this snippet for browsers that support DOM 2 Events. For a more foolproof simulation, fill in the mouse position using initMouseEvent instead.

// DOM 2 Events
var dispatchMouseEvent = function(target, var_args) {
  var e = document.createEvent("MouseEvents");
  // If you need clientX, clientY, etc., you can call
  // initMouseEvent instead of initEvent
  e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
dispatchMouseEvent(element, 'mouseover', true, true);
dispatchMouseEvent(element, 'mousedown', true, true);
dispatchMouseEvent(element, 'click', true, true);
dispatchMouseEvent(element, 'mouseup', true, true);

When you fire a simulated click event, the browser will actually fire the default action (e.g. navigate to the link's href, or submit a form).

In IE, the equivalent snippet is this (unverified since I don't have IE). I don't think you can give the event handler mouse positions.

// IE 5.5+
element.fireEvent("onmouseover");
element.fireEvent("onmousedown");
element.fireEvent("onclick");  // or element.click()
element.fireEvent("onmouseup");

Simulating keydown and keypress

You can simulate keydown and keypress events, but unfortunately in Chrome they only fire the event handlers and don't perform any of the default actions. I think this is because the DOM 3 Events working draft describes this funky order of key events:

1. keydown (often has default action such as fire click, submit, or textInput events)
2. keypress (if the key isn't just a modifier key like Shift or Ctrl)
3. (keydown, keypress) with repeat=true if the user holds down the button
4. default actions of keydown!!
5. keyup

This means that you have to (while combing the HTML5 and DOM 3 Events drafts) simulate a large amount of what the browser would otherwise do. I hate it when I have to do that. For example, this is roughly how to simulate a key press on an input or textarea.

// DOM 3 Events
var dispatchKeyboardEvent = function(target, initKeyboradEvent_args) {
  var e = document.createEvent("KeyboardEvents");
  e.initKeyboardEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
var dispatchTextEvent = function(target, initTextEvent_args) {
  var e = document.createEvent("TextEvent");
  e.initTextEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
var dispatchSimpleEvent = function(target, type, canBubble, cancelable) {
  var e = document.createEvent("Event");
  e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};

var canceled = !dispatchKeyboardEvent(element,
    'keydown', true, true,  // type, bubbles, cancelable
    null,  // window
    'h',  // key
    0, // location: 0=standard, 1=left, 2=right, 3=numpad, 4=mobile, 5=joystick
    '');  // space-sparated Shift, Control, Alt, etc.
dispatchKeyboardEvent(
    element, 'keypress', true, true, null, 'h', 0, '');
if (!canceled) {
  if (dispatchTextEvent(element, 'textInput', true, true, null, 'h', 0)) {
    element.value += 'h';
    dispatchSimpleEvent(element, 'input', false, false);
    // not supported in Chrome yet
    // if (element.form) element.form.dispatchFormInput();
    dispatchSimpleEvent(element, 'change', false, false);
    // not supported in Chrome yet
    // if (element.form) element.form.dispatchFormChange();
  }
}
dispatchKeyboardEvent(
    element, 'keyup', true, true, null, 'h', 0, '');

I don't think it is possible to simulate key events in IE.

You might produce the wrong behavior because the File-Api fs.readdir does not return a promise. It only takes a callback. If you want to go with the async-await syntax you could 'promisify' the function like this:

function readdirAsync(path) {
  return new Promise(function (resolve, reject) {
    fs.readdir(path, function (error, result) {
      if (error) {
        reject(error);
      } else {
        resolve(result);
      }
    });
  });
}

and call it instead:

names = await readdirAsync('path/to/dir');

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Ok I did it with some trick ;) First build a UITextField and increased it's size like this :

CGRect frameRect = textField.frame;
        frameRect.size.height = 53;
        textField.frame = frameRect;

Then build a UITextView exactly in the same area that u made my UITextField, and deleted its background color. Now it looks like that u have a multiple lines TextField !

It vastly depends on how you intend to take this input, i.e. how your program is intending to interact with the user.

The simplest example is if you're bundling an executable - in this case the user can just provide the array elements on the command-line and the corresponding array will be accessible from your application's main method.

Alternatively, if you're writing some kind of webapp, you'd want to accept values in the doGet/doPost method of your application, either by manually parsing query parameters, or by serving the user with an HTML form that submits to your parsing page.

If it's a Swing application you would probably want to pop up a text box for the user to enter input. And in other contexts you may read the values from a database/file, where they have previously been deposited by the user.

Basically, reading input as arrays is quite easy, once you have worked out a way to get input. You need to think about the context in which your application will run, and how your users would likely expect to interact with this type of application, then decide on an I/O architecture that makes sense.

System.Windows.Forms.Control.MousePosition

Gets the position of the mouse cursor in screen coordinates. "The Position property is identical to the Control.MousePosition property."

In my projects, we usually call server side method like this:

in JavaScript:

document.getElementById("UploadButton").click();

Server side control:

<asp:Button runat="server" ID="UploadButton" Text="" style="display:none;" OnClick="UploadButton_Click" />

C#:

protected void Upload_Click(object sender, EventArgs e)
{

}

Adding Class to <li> tag without editing functions.php file:

1. Go to Appearance -> Menu -> Screen Options -> CSS Classes
2. You will get CSS Class option enabled in Menu Items Window

Essentially you have to have admin rights (directly or indirectly) to the repository to do this. You can either configure the repository to allow all users to do this, or you can modify the log message directly on the server.

See this part of the Subversion FAQ (emphasis mine):

Log messages are kept in the repository as properties attached to each revision. By default, the log message property (svn:log) cannot be edited once it is committed. That is because changes to revision properties (of which svn:log is one) cause the property's previous value to be permanently discarded, and Subversion tries to prevent you from doing this accidentally. However, there are a couple of ways to get Subversion to change a revision property.

The first way is for the repository administrator to enable revision property modifications. This is done by creating a hook called "pre-revprop-change" (see this section in the Subversion book for more details about how to do this). The "pre-revprop-change" hook has access to the old log message before it is changed, so it can preserve it in some way (for example, by sending an email). Once revision property modifications are enabled, you can change a revision's log message by passing the --revprop switch to svn propedit or svn propset, like either one of these:

$svn propedit -r N --revprop svn:log URL 
$svn propset -r N --revprop svn:log "new log message" URL 

where N is the revision number whose log message you wish to change, and URL is the location of the repository. If you run this command from within a working copy, you can leave off the URL.

The second way of changing a log message is to use svnadmin setlog. This must be done by referring to the repository's location on the filesystem. You cannot modify a remote repository using this command.

$ svnadmin setlog REPOS_PATH -r N FILE

where REPOS_PATH is the repository location, N is the revision number whose log message you wish to change, and FILE is a file containing the new log message. If the "pre-revprop-change" hook is not in place (or you want to bypass the hook script for some reason), you can also use the --bypass-hooks option. However, if you decide to use this option, be very careful. You may be bypassing such things as email notifications of the change, or backup systems that keep track of revision properties.

Well, you're missing the letter 'd' in url("~/fonts/Lato-Bol.ttf"); - but assuming that's not it, I would open up your page with developer tools in Chrome and make sure there's no errors loading any of the files (you would probably see an issue in the JavaScript console, or you can check the Network tab and see if anything is red).

(I don't see anything obviously wrong with the code you have posted above)

Other things to check: 1) Are you including your CSS file in your html above the lines where you are trying to use the font-family style? 2) What do you see in the CSS panel in the developer tools for that div? Is font-family: lato crossed out?

You put your template in the wrong place. From the Flask docs:

Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates

I had the same problem, but I fixed it using the method

requestLayout();

from the class ListView

I had the pleasure of experiencing this random problem in Visual Studio 2017 Enterprise.

I tried every solution here, and it didn't work, including the Visual Studio repair (which takes a while). Several hours in, I thought maybe I should actually check the ActivityLog.xml file.

I uninstalled the offending extension from the 'Developer Command Prompt for VS2017' as an administrator since Visual Studio just freezed after open and nothing could be clicked.

Steps to uninstall - courtesy of jessehouwing.net

1. Find the vsix file you used to install the extension.
2. Open it in your favorite archiver (mine is 7-Zip).
3. Grab the extension's Id from the Identity node from the extension.vsixmanifest.
4. Run (in my case) vsixinstaller /u:Microsoft.VisualStudio.LiveShare to remove the extension.

Why :not just use two :not:

input:not([type="radio"]):not([type="checkbox"])

_{Yes, it is intentional}

This is because of ng-include which creates a new child scope, so $scope.lineText isn’t changed. I think that this refers to the current scope, so this.lineText should be set.

Of course, Insert or AddFirst will do the trick, but you could always do:

myList.Reverse();
myList.Add(item);
myList.Reverse();

Use a struct to simulate the data members of a class. In terms of method scope you can simulate private methods by placing the private function prototypes in the .c file and the public functions in the .h file.

If you are looking for swift code:

var titleLabel = UILabel()
titleLabel.font = UIFont(name: "HelveticaNeue-UltraLight",
                         size: 20.0)

You will have to override the OnPaint method, call the base implementation and the paint your own text.

You will need to create your own CustomProgressBar and then override OnPaint to draw what ever text you want.

Custom Progress Bar Class

namespace ProgressBarSample
{

public enum ProgressBarDisplayText
{
    Percentage,
    CustomText
}

class CustomProgressBar: ProgressBar
{
    //Property to set to decide whether to print a % or Text
    public ProgressBarDisplayText DisplayStyle { get; set; }

    //Property to hold the custom text
    public String CustomText { get; set; }

    public CustomProgressBar()
    {
        // Modify the ControlStyles flags
        //http://msdn.microsoft.com/en-us/library/system.windows.forms.controlstyles.aspx
        SetStyle(ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true);
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        Rectangle rect = ClientRectangle;
        Graphics g = e.Graphics;

        ProgressBarRenderer.DrawHorizontalBar(g, rect);
        rect.Inflate(-3, -3);
        if (Value > 0)
        {
            // As we doing this ourselves we need to draw the chunks on the progress bar
            Rectangle clip = new Rectangle(rect.X, rect.Y, (int)Math.Round(((float)Value / Maximum) * rect.Width), rect.Height);
            ProgressBarRenderer.DrawHorizontalChunks(g, clip);
        }

        // Set the Display text (Either a % amount or our custom text
        string text = DisplayStyle == ProgressBarDisplayText.Percentage ? Value.ToString() + '%' : CustomText;


        using (Font f = new Font(FontFamily.GenericSerif, 10))
        {

            SizeF len = g.MeasureString(text, f);
            // Calculate the location of the text (the middle of progress bar)
            // Point location = new Point(Convert.ToInt32((rect.Width / 2) - (len.Width / 2)), Convert.ToInt32((rect.Height / 2) - (len.Height / 2)));
            Point location = new Point(Convert.ToInt32((Width / 2) - len.Width / 2), Convert.ToInt32((Height / 2) - len.Height / 2)); 
            // The commented-out code will centre the text into the highlighted area only. This will centre the text regardless of the highlighted area.
            // Draw the custom text
            g.DrawString(text, f, Brushes.Red, location);
        }
    }
}
}

            }

            btnReset.Enabled = true;


        }


    }
}

For cv::Mat_<T> mat just use mat(row, col)

Accessing elements of a matrix with specified type cv::Mat_< _Tp > is more comfortable, as you can skip the template specification. This is pointed out in the documentation as well.

code:

cv::Mat1d mat0 = cv::Mat1d::zeros(3, 4);
std::cout << "mat0:\n" << mat0 << std::endl;
std::cout << "element: " << mat0(2, 0) << std::endl;
std::cout << std::endl;

cv::Mat1d mat1 = (cv::Mat1d(3, 4) <<
    1, NAN, 10.5, NAN,
    NAN, -99, .5, NAN,
    -70, NAN, -2, NAN);
std::cout << "mat1:\n" << mat1 << std::endl;
std::cout << "element: " << mat1(0, 2) << std::endl;
std::cout << std::endl;

cv::Mat mat2 = cv::Mat(3, 4, CV_32F, 0.0);
std::cout << "mat2:\n" << mat2 << std::endl;
std::cout << "element: " << mat2.at<float>(2, 0) << std::endl;
std::cout << std::endl;

output:

mat0:
[0, 0, 0, 0;
 0, 0, 0, 0;
 0, 0, 0, 0]
element: 0

mat1:
[1, nan, 10.5, nan;
 nan, -99, 0.5, nan;
 -70, nan, -2, nan]
element: 10.5

mat2:
[0, 0, 0, 0;
 0, 0, 0, 0;
 0, 0, 0, 0]
element: 0

There are many great open source projects that make detection a lot easier. To name two:

1. PHP mobile detect
2. WURFL

For set value when your control is FormGroup can use this example

this.clientForm.controls['location'].setValue({
      latitude: position.coords.latitude,
      longitude: position.coords.longitude
    });

You can create new users using the CREATE USER statement, and give rights to them using GRANT.

This might be considered one of the options. now if you wanted to load a yml file ( which did not get loaded by default on applying the above annotations) the trick is to use

@ContextConfiguration(classes= {...}, initializers={ConfigFileApplicationContextInitializer.class})

Here is a sample code

@RunWith(SpringRunner.class)
@ActiveProfiles("test")
@DirtiesContext
@ContextConfiguration(classes= {DataSourceTestConfig.class}, initializers = {ConfigFileApplicationContextInitializer.class})
public class CustomDateDeserializerTest {


    private ObjectMapper objMapper;

    @Before
    public void setUp() {
        objMapper = new ObjectMapper();

    }

    @Test
    public void test_dateDeserialization() {

    }
}

Again make sure that the setup config java file - here DataSourceTestConfig.java contains the following property values.

@Configuration
@ActiveProfiles("test")
@TestPropertySource(properties = { "spring.config.location=classpath:application-test.yml" })
public class DataSourceTestConfig implements EnvironmentAware {

    private Environment env;

    @Bean
    @Profile("test")
    public DataSource testDs() {
       HikariDataSource ds = new HikariDataSource();

        boolean isAutoCommitEnabled = env.getProperty("spring.datasource.hikari.auto-commit") != null ? Boolean.parseBoolean(env.getProperty("spring.datasource.hikari.auto-commit")):false;
        ds.setAutoCommit(isAutoCommitEnabled);
        // Connection test query is for legacy connections
        //ds.setConnectionInitSql(env.getProperty("spring.datasource.hikari.connection-test-query"));
        ds.setPoolName(env.getProperty("spring.datasource.hikari.pool-name"));
        ds.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
        long timeout = env.getProperty("spring.datasource.hikari.idleTimeout") != null ? Long.parseLong(env.getProperty("spring.datasource.hikari.idleTimeout")): 40000;
        ds.setIdleTimeout(timeout);
        long maxLifeTime = env.getProperty("spring.datasource.hikari.maxLifetime") != null ? Long.parseLong(env.getProperty("spring.datasource.hikari.maxLifetime")): 1800000 ;
        ds.setMaxLifetime(maxLifeTime);
        ds.setJdbcUrl(env.getProperty("spring.datasource.url"));
        ds.setPoolName(env.getProperty("spring.datasource.hikari.pool-name"));
        ds.setUsername(env.getProperty("spring.datasource.username"));
        ds.setPassword(env.getProperty("spring.datasource.password"));
        int poolSize = env.getProperty("spring.datasource.hikari.maximum-pool-size") != null ? Integer.parseInt(env.getProperty("spring.datasource.hikari.maximum-pool-size")): 10;
        ds.setMaximumPoolSize(poolSize);

        return ds;
    }

    @Bean
    @Profile("test")
    public JdbcTemplate testJdbctemplate() {
        return new JdbcTemplate(testDs());
    }

    @Bean
    @Profile("test")
    public NamedParameterJdbcTemplate testNamedTemplate() {
        return new NamedParameterJdbcTemplate(testDs());
    }

    @Override
    public void setEnvironment(Environment environment) {
        // TODO Auto-generated method stub
        this.env = environment;
    }
}

Most answers you find on contenteditable cursor positioning are fairly simplistic in that they only cater for inputs with plain vanilla text. Once you using html elements within the container the text entered gets split into nodes and distributed liberally across a tree structure.

To set the cursor position I have this function which loops round all the child text nodes within the supplied node and sets a range from the start of the initial node to the chars.count character:

function createRange(node, chars, range) {
    if (!range) {
        range = document.createRange()
        range.selectNode(node);
        range.setStart(node, 0);
    }

    if (chars.count === 0) {
        range.setEnd(node, chars.count);
    } else if (node && chars.count >0) {
        if (node.nodeType === Node.TEXT_NODE) {
            if (node.textContent.length < chars.count) {
                chars.count -= node.textContent.length;
            } else {
                range.setEnd(node, chars.count);
                chars.count = 0;
            }
        } else {
           for (var lp = 0; lp < node.childNodes.length; lp++) {
                range = createRange(node.childNodes[lp], chars, range);

                if (chars.count === 0) {
                    break;
                }
            }
        }
    } 

    return range;
};

I then call the routine with this function:

function setCurrentCursorPosition(chars) {
    if (chars >= 0) {
        var selection = window.getSelection();

        range = createRange(document.getElementById("test").parentNode, { count: chars });

        if (range) {
            range.collapse(false);
            selection.removeAllRanges();
            selection.addRange(range);
        }
    }
};

The range.collapse(false) sets the cursor to the end of the range. I've tested it with the latest versions of Chrome, IE, Mozilla and Opera and they all work fine.

PS. If anyone is interested I get the current cursor position using this code:

function isChildOf(node, parentId) {
    while (node !== null) {
        if (node.id === parentId) {
            return true;
        }
        node = node.parentNode;
    }

    return false;
};

function getCurrentCursorPosition(parentId) {
    var selection = window.getSelection(),
        charCount = -1,
        node;

    if (selection.focusNode) {
        if (isChildOf(selection.focusNode, parentId)) {
            node = selection.focusNode; 
            charCount = selection.focusOffset;

            while (node) {
                if (node.id === parentId) {
                    break;
                }

                if (node.previousSibling) {
                    node = node.previousSibling;
                    charCount += node.textContent.length;
                } else {
                     node = node.parentNode;
                     if (node === null) {
                         break
                     }
                }
           }
      }
   }

    return charCount;
};

The code does the opposite of the set function - it gets the current window.getSelection().focusNode and focusOffset and counts backwards all text characters encountered until it hits a parent node with id of containerId. The isChildOf function just checks before running that the suplied node is actually a child of the supplied parentId.

The code should work straight without change, but I have just taken it from a jQuery plugin I've developed so have hacked out a couple of this's - let me know if anything doesn't work!

ssh -t -t [email protected] << EOF
echo SOMEPASSWORD | sudo -S do something
sudo do something else
exit
EOF

You might want to check you spaces and tabs. A tab is a default of 4 spaces. However, your "if" and "elif" match, so I am not quite sure why. Go into Options in the top bar, and click "Configure IDLE". Check the Indentation Width on the right in Fonts/Tabs, and make sure your indents have that many spaces.

Gory details

A DLL uses the PE executable format, and it's not too tricky to read that information out of the file.

See this MSDN article on the PE File Format for an overview. You need to read the MS-DOS header, then read the IMAGE_NT_HEADERS structure. This contains the IMAGE_FILE_HEADER structure which contains the info you need in the Machine member which contains one of the following values

• IMAGE_FILE_MACHINE_I386 (0x014c)
• IMAGE_FILE_MACHINE_IA64 (0x0200)
• IMAGE_FILE_MACHINE_AMD64 (0x8664)

This information should be at a fixed offset in the file, but I'd still recommend traversing the file and checking the signature of the MS-DOS header and the IMAGE_NT_HEADERS to be sure you cope with any future changes.

Use ImageHelp to read the headers...

You can also use the ImageHelp API to do this - load the DLL with LoadImage and you'll get a LOADED_IMAGE structure which will contain a pointer to an IMAGE_NT_HEADERS structure. Deallocate the LOADED_IMAGE with ImageUnload.

...or adapt this rough Perl script

Here's rough Perl script which gets the job done. It checks the file has a DOS header, then reads the PE offset from the IMAGE_DOS_HEADER 60 bytes into the file.

It then seeks to the start of the PE part, reads the signature and checks it, and then extracts the value we're interested in.

#!/usr/bin/perl
#
# usage: petype <exefile>
#
$exe = $ARGV[0];

open(EXE, $exe) or die "can't open $exe: $!";
binmode(EXE);
if (read(EXE, $doshdr, 64)) {

   ($magic,$skip,$offset)=unpack('a2a58l', $doshdr);
   die("Not an executable") if ($magic ne 'MZ');

   seek(EXE,$offset,SEEK_SET);
   if (read(EXE, $pehdr, 6)){
       ($sig,$skip,$machine)=unpack('a2a2v', $pehdr);
       die("No a PE Executable") if ($sig ne 'PE');

       if ($machine == 0x014c){
            print "i386\n";
       }
       elsif ($machine == 0x0200){
            print "IA64\n";
       }
       elsif ($machine == 0x8664){
            print "AMD64\n";
       }
       else{
            printf("Unknown machine type 0x%lx\n", $machine);
       }
   }
}

close(EXE);

Query the sysdepends table:

SELECT distinct schema_name(dependentObject.uid) as schema, 
       dependentObject.*
 FROM sysdepends d 
INNER JOIN sysobjects o on d.id = o.id 
INNER JOIN sysobjects dependentObject on d.depid = dependentObject.id
WHERE o.name = 'TableName'

A way to look just for views/functions/triggers/procedures that reference the object (or any given text) by name is:

SELECT distinct schema_name(so.uid) + '.' + so.name 
  FROM syscomments sc 
 INNER JOIN  sysobjects so on sc.id = so.id 
 WHERE sc.text like '%Name%'

if you do not wish to go for custom view then you can use following approach. e.g. ImageView

// class level

GestureDetector gestureDetector;
boolean tapped;
ImageView imageView;

// inside onCreate of Activity or Fragment
gestureDetector = new GestureDetector(context,new GestureListener());

//--------------------------------------------------------------------------------

public class GestureListener extends
        GestureDetector.SimpleOnGestureListener {

    @Override
    public boolean onDown(MotionEvent e) {

        return true;
    }

    // event when double tap occurs
    @Override
    public boolean onDoubleTap(MotionEvent e) {

        tapped = !tapped;

        if (tapped) {



        } else {



        }

        return true;
    }
}

//--------------------------------------------------------------------------------

for ImageView

imageView.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            return gestureDetector.onTouchEvent(event);
        }

    });

Here's a vanilla js example to trigger any event:

function triggerEvent(el, type){
if ('createEvent' in document) {
        // modern browsers, IE9+
        var e = document.createEvent('HTMLEvents');
        e.initEvent(type, false, true);
        el.dispatchEvent(e);
    } else {
        // IE 8
        var e = document.createEventObject();
        e.eventType = type;
        el.fireEvent('on'+e.eventType, e);
    }
}

Here's an alternative, instead of adding an incomplete.flag file to every dir you want to exclude, generate a file that contains a listing of all the directories you want to exclude and then use the excludesfile attribute. Something like this:

<fileset dir="${basedir}" excludesfile="FileWithExcludedDirs.properties">
  <include name="locale/"/>
  <exclude name="locale/*/incomplete.flag">
</fileset>

Hope it helps.

Associative array in PHP actually considered as a dictionary.

An array in PHP is actually an ordered map. A map is a type that associates values to keys. it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more.

<?php
$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

// Using the short array syntax
$array = [
    "foo" => "bar",
    "bar" => "foo",
];
?>

An array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index.

Have a look at the example in this link :

http://docs.angularjs.org/api/ngSanitize.$sanitize

Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :

If you already have done all this :

// My magic HTML string function.
function htmlString (str) {
    return "<h1>" + str + "</h1>";
}

function Ctrl ($scope) {
  var str = "HELLO!";
  $scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];

Then in your html within the scope of that controller, you could

<div ng-bind-html="htmlString"></div>

print((df.count(), len(df.columns)))

is easier for smaller datasets.

However if the dataset is huge, an alternative approach would be to use pandas and arrows to convert the dataframe to pandas df and call shape

spark.conf.set("spark.sql.execution.arrow.enabled", "true")
spark.conf.set("spark.sql.crossJoin.enabled", "true")
print(df.toPandas().shape)

And this famous code from a famous JS Ninja

var isPrime = n => Array(Math.ceil(Math.sqrt(n)+1)).fill().map((e,i)=>i).slice(2).every(m => n%m);

console.log(Array(100).fill().map((e,i)=>i+1).slice(1).filter(isPrime));

The first one is invalid syntax. You cannot have object properties inside a plain array. The second one is right although it is not strict JSON. It's a relaxed form of JSON wherein quotes in string keys are omitted.

This tutorial by Patrick Hunlock, may help to learn about JSON and this site may help to validate JSON.

Gradle Build Tools 2.2.0+ - Everything just works

This is the correct way to do it

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

For Yii2: This should be safer Yii::$app->request->absoluteUrl rather than Yii::$app->request->url

You can disable expandtab option from within Vim as below:

:set expandtab!

or

:set noet

PS: And set it back when you are done with inserting tab, with "set expandtab" or "set et"

PS: If you have tab set equivalent to 4 spaces in .vimrc (softtabstop), you may also like to set it to 8 spaces in order to be able to insert a tab by pressing tab key once instead of twice (set softtabstop=8).

To complete BoBby Jack, the use of DateTime OBject, if you have php 5.2.2+ :

if(new DateTime() > new DateTime($var)){
    // $var is before today so use it

}

Many times when crawling we run into problems where content that is rendered on the page is generated with Javascript and therefore scrapy is unable to crawl for it (eg. ajax requests, jQuery craziness).

However, if you use Scrapy along with the web testing framework Selenium then we are able to crawl anything displayed in a normal web browser.

Some things to note:

• You must have the Python version of Selenium RC installed for this to work, and you must have set up Selenium properly. Also this is just a template crawler. You could get much crazier and more advanced with things but I just wanted to show the basic idea. As the code stands now you will be doing two requests for any given url. One request is made by Scrapy and the other is made by Selenium. I am sure there are ways around this so that you could possibly just make Selenium do the one and only request but I did not bother to implement that and by doing two requests you get to crawl the page with Scrapy too.

• This is quite powerful because now you have the entire rendered DOM available for you to crawl and you can still use all the nice crawling features in Scrapy. This will make for slower crawling of course but depending on how much you need the rendered DOM it might be worth the wait.

If you have a look at the documentation for Html.fromHtml(text) you'll see it says:

Any <img> tags in the HTML will display as a generic replacement image which your program can then go through and replace with real images.

If you don't want to do this replacement yourself you can use the other Html.fromHtml() method which takes an Html.TagHandler and an Html.ImageGetter as arguments as well as the text to parse.

In your case you could parse null as for the Html.TagHandler but you'd need to implement your own Html.ImageGetter as there isn't a default implementation.

However, the problem you're going to have is that the Html.ImageGetter needs to run synchronously and if you're downloading images from the web you'll probably want to do that asynchronously. If you can add any images you want to display as resources in your application the your ImageGetter implementation becomes a lot simpler. You could get away with something like:

private class ImageGetter implements Html.ImageGetter {

    public Drawable getDrawable(String source) {
        int id;

        if (source.equals("stack.jpg")) {
            id = R.drawable.stack;
        }
        else if (source.equals("overflow.jpg")) {
            id = R.drawable.overflow;
        }
        else {
            return null;
        }

        Drawable d = getResources().getDrawable(id);
        d.setBounds(0,0,d.getIntrinsicWidth(),d.getIntrinsicHeight());
        return d;
    }
};

You'd probably want to figure out something smarter for mapping source strings to resource IDs though.

By definition, a UUID is 32 hexadecimal digits, separated in 5 groups by hyphens, just as you have described. You shouldn't miss any with your regular expression.

http://en.wikipedia.org/wiki/Uuid#Definition

$result = mysql_query($sql);

//Try This code is running perfectly !!!!!!!!!!

Here is what I have for mine.

Essentially you are utilizing the onfocus and onblur commands in the tag to trigger the appropriate javascript. It could be as simple as:

<span><input name="login_text_password" type="text" value="Password" onfocus="this.select(); this.setAttribute('type','password');" onblur="this.select(); this.setAttribute('type','text');" /></span>

An evolved version of this basic functionality checks for and empty string and returns the password input back to the original "Password" in the event of a null textbox:

    <script type="text/javascript">
        function password_set_attribute() {
            if (document.getElementsByName("login_text_password")[0].value.replace(/\s+/g, ' ') == "" || document.getElementsByName[0].value == null) {
                document.getElementsByName("login_text_password")[0].setAttribute('type','text')
                document.getElementsByName("login_text_password")[0].value = 'Password';
            }
            else {
                document.getElementsByName("login_text_password")[0].setAttribute('type','password')
            }
        }
    </script> 

Where HTML looks like:

<span><input name="login_text_password" class="roundCorners" type="text" value="Password" onfocus="this.select(); this.setAttribute('type','password');" onblur="password_set_attribute();" /></span>

The compiler is already telling you, it's not value but variable. You are looking for -Wno-unused-variable. Also, try g++ --help=warnings to see a list of available options.

Open 'postgresql.conf' in you favourite editor. Look for the variable 'unix_socket_directories', it will most likely look like this:

unix_socket_directories = '/private/tmp/'

Change the line to this:

unix_socket_directories = '/var/pgsql_socket/'

Note if you want the socket files in more than one directory comma separate them.

You basically need to do this:

• include the target hash into the link pointing to the other page (href="other_page.html#section")
• in your ready handler clear the hard jump scroll normally dictated by the hash and as soon as possible scroll the page back to the top and call jump() - you'll need to do this asynchronously
• in jump() if no event is given, make location.hash the target
• also this technique might not catch the jump in time, so you'll better hide the html,body right away and show it back once you scrolled it back to zero

This is your code with the above added:

var jump=function(e)
{
   if (e){
       e.preventDefault();
       var target = $(this).attr("href");
   }else{
       var target = location.hash;
   }

   $('html,body').animate(
   {
       scrollTop: $(target).offset().top
   },2000,function()
   {
       location.hash = target;
   });

}

$('html, body').hide();

$(document).ready(function()
{
    $('a[href^=#]').bind("click", jump);

    if (location.hash){
        setTimeout(function(){
            $('html, body').scrollTop(0).show();
            jump();
        }, 0);
    }else{
        $('html, body').show();
    }
});

Verified working in Chrome/Safari, Firefox and Opera. I don't know about IE though.

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

Pull changes first:

git pull origin branch_name

Use this also

NSString *ChkStr = [MyString substringWithRange:NSMakeRange(5, 26)];

Note - Your NSMakeRange(start, end) should be NSMakeRange(start, end- start);

You'll want to install the sshpass program. Then:

sshpass -p YOUR_PASSWORD sftp -oBatchMode=no -b YOUR_COMMAND_FILE_PATH USER@HOST

Obviously, it's better to setup public key authentication. Only use this if that's impossible to do, for whatever reason.

How to create FLUTTER project in android studio in fedora:-

I have installed following:- 1 Android studio 2 Then do following:-

Start Android Studio. Open plugin preferences (Preferences > Plugins on macOS, File > Settings > Plugins on Windows & Linux). Select Marketplace, select the Flutter plugin and click Install. Click Yes when prompted to install the Dart plugin. Click Restart when prompted.

4:- Now create project by clicking new flutter project and do following:- * Choose Flutter Application from the list of configurations * Fill the name and other things * For flutter sdk click and install flutter sdk and specify the location of downloading and after downloading completion, choose that sdk path, this will load your FLutter sdk.

Rest do steps as per your need to create project

For delays as large as one minute, sleep() is a nice choice.

If someday, you want to pause on delays smaller than one second, you may want to consider poll() with a timeout.

Both are POSIX.

Of course Fibonacci numbers can be computed in O(n) by applying the Binet formula:

from math import floor, sqrt

def fib(n):                                                     
    return int(floor(((1+sqrt(5))**n-(1-sqrt(5))**n)/(2**n*sqrt(5))+0.5))

As the commenters note it's not O(1) but O(n) because of 2**n. Also a difference is that you only get one value, while with recursion you get all values of Fibonacci(n) up to that value.

Using Stream

private static void copyFileUsingStream(File source, File dest) throws IOException {
    InputStream is = null;
    OutputStream os = null;
    try {
        is = new FileInputStream(source);
        os = new FileOutputStream(dest);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = is.read(buffer)) > 0) {
            os.write(buffer, 0, length);
        }
    } finally {
        is.close();
        os.close();
    }
}

Using Channel

private static void copyFileUsingChannel(File source, File dest) throws IOException {
    FileChannel sourceChannel = null;
    FileChannel destChannel = null;
    try {
        sourceChannel = new FileInputStream(source).getChannel();
        destChannel = new FileOutputStream(dest).getChannel();
        destChannel.transferFrom(sourceChannel, 0, sourceChannel.size());
       }finally{
           sourceChannel.close();
           destChannel.close();
       }
}

Using Apache Commons IO lib:

private static void copyFileUsingApacheCommonsIO(File source, File dest) throws IOException {
    FileUtils.copyFile(source, dest);
}

Using Java SE 7 Files class:

private static void copyFileUsingJava7Files(File source, File dest) throws IOException {
    Files.copy(source.toPath(), dest.toPath());
}

Or try Googles Guava :

Compare time:

    File source = new File("/Users/sidikov/tmp/source.avi");
    File dest = new File("/Users/sidikov/tmp/dest.avi");


    //copy file conventional way using Stream
    long start = System.nanoTime();
    copyFileUsingStream(source, dest);
    System.out.println("Time taken by Stream Copy = "+(System.nanoTime()-start));
     
    //copy files using java.nio FileChannel
    source = new File("/Users/sidikov/tmp/sourceChannel.avi");
    dest = new File("/Users/sidikov/tmp/destChannel.avi");
    start = System.nanoTime();
    copyFileUsingChannel(source, dest);
    System.out.println("Time taken by Channel Copy = "+(System.nanoTime()-start));
     
    //copy files using apache commons io
    source = new File("/Users/sidikov/tmp/sourceApache.avi");
    dest = new File("/Users/sidikov/tmp/destApache.avi");
    start = System.nanoTime();
    copyFileUsingApacheCommonsIO(source, dest);
    System.out.println("Time taken by Apache Commons IO Copy = "+(System.nanoTime()-start));
     
    //using Java 7 Files class
    source = new File("/Users/sidikov/tmp/sourceJava7.avi");
    dest = new File("/Users/sidikov/tmp/destJava7.avi");
    start = System.nanoTime();
    copyFileUsingJava7Files(source, dest);
    System.out.println("Time taken by Java7 Files Copy = "+(System.nanoTime()-start));

You can try this which I find in another question.

There is a chrome extension called Enhanced Github

It will add a download button directly to the right of each file.

Adding on: yes, you can use the bottom-right UI to configure the space settings. But if you have existing code that's not formatted to the new spacing, then you can right-click anywhere within the file and click Format Document. Took me a while to figure this out until I stumbled on this issue.

Format Document menu

In Android Studio (mine is 2.3.1) go to File - Project Structure:

Remove Object from NSArray with this Method:

-(NSArray *) removeObjectFromArray:(NSArray *) array withIndex:(NSInteger) index {
    NSMutableArray *modifyableArray = [[NSMutableArray alloc] initWithArray:array];
    [modifyableArray removeObjectAtIndex:index];
    return [[NSArray alloc] initWithArray:modifyableArray];
}

ObjectMapper.readTree() can do this in one line:

mapper.readTree(json).toPrettyString();

Since readTree produces a JsonNode, this should pretty much always produce equivalent pretty-formatted JSON, as it JsonNode is a direct tree representation of the underlying JSON string.

Prior to Jackson 2.10

The JsonNode.toPrettyString() method was added in Jackson 2.10. Prior to that, a second call to the ObjectMapper was needed to write the pretty formatted result:

mapper.writerWithDefaultPrettyPrinter()
        .writeValueAsString(mapper.readTree(json));

Here you go:

var yourArray = [String]()

The above also works for other types and not just strings. It's just an example.

Adding Values to It

I presume you'll eventually want to add a value to it!

yourArray.append("String Value")

Or

let someString = "You can also pass a string variable, like this!"
yourArray.append(someString)

Add by Inserting

Once you have a few values, you can insert new values instead of appending. For example, if you wanted to insert new objects at the beginning of the array (instead of appending them to the end):

yourArray.insert("Hey, I'm first!", atIndex: 0)

Or you can use variables to make your insert more flexible:

let lineCutter = "I'm going to be first soon."
let positionToInsertAt = 0
yourArray.insert(lineCutter, atIndex: positionToInsertAt)

You May Eventually Want to Remove Some Stuff

var yourOtherArray = ["MonkeysRule", "RemoveMe", "SwiftRules"]
yourOtherArray.remove(at: 1)

The above works great when you know where in the array the value is (that is, when you know its index value). As the index values begin at 0, the second entry will be at index 1.

Removing Values Without Knowing the Index

But what if you don't? What if yourOtherArray has hundreds of values and all you know is you want to remove the one equal to "RemoveMe"?

if let indexValue = yourOtherArray.index(of: "RemoveMe") {
    yourOtherArray.remove(at: indexValue)
}

This should get you started!

Jim Hall's answer is preferrable because while it indeed does not scroll to the bottom when you're scrolled up, it is also pure CSS.

Very much unfortunately however, this is not a stable solution: In chrome (possibly due to the 1-px-issue described by dotnetCarpenter above), scrollTop behaves inaccurately by 1 pixel, even without user interaction (upon element add). You can set scrollTop = scrollHeight - clientHeight, but that will keep the div in position when another element is added, aka the "keep itself at bottom" feature is not working anymore.

So, in short, adding a small amount of Javascript (sigh) will fix this and fulfill all requirements:

Something like https://codepen.io/anon/pen/pdrLEZ this (example by Coo), and after adding an element to the list, also the following:

container = ...
if(container.scrollHeight - container.clientHeight - container.scrollTop <= 29) {
    container.scrollTop = container.scrollHeight - container.clientHeight;
}

where 29 is the height of one line.

So, when the user scrolls up half a line (if that is even possible?), the Javascript will ignore it and scroll to the bottom. But I guess this is neglectible. And, it fixes the Chrome 1 px thingy.

I've found in the cases where $_SERVER['HTTP_REFERER'] doesn't work (I'm looking at you, Safari), $_SERVER['REDIRECT_SCRIPT_URI'] has been a useful backup.

tl;dr

ChronoUnit.DAYS.between( 
    LocalDate.parse( "1999-12-28" ) , 
    LocalDate.parse( "12/31/1999" , DateTimeFormatter.ofPattern( "MM/dd/yyyy" ) ) 
)

Details

Other answers are outdated. The old date-time classes bundled with the earliest versions of Java have proven to be poorly designed, confusing, and troublesome. Avoid them.

java.time

The Joda-Time project was highly successful as a replacement for those old classes. These classes provided the inspiration for the java.time framework built into Java 8 and later.

Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

Parsing strings

If your input strings are in standard ISO 8601 format, the LocalDate class can directly parse the string.

LocalDate start = LocalDate.parse( "1999-12-28" );

If not in ISO 8601 format, define a formatting pattern with DateTimeFormatter.

String input = "12/31/1999";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern( "MM/dd/yyyy" );
LocalDate stop = LocalDate.parse( input , formatter );

Elapsed days via ChronoUnit

Now get a count of days elapsed between that pair of LocalDate objects. The ChronoUnit enum calculates elapsed time.

long totalDays = ChronoUnit.DAYS.between( start , stop ) ; 

If you are unfamiliar with Java enums, know they are far more powerful and useful that conventional enums in most other programming languages. See the Enum class doc, the Oracle Tutorial, and Wikipedia to learn more.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

When you mark your method as @Transactional, occurrence of any exception inside your method will mark the surrounding TX as roll-back only (even if you catch them). You can use other attributes of @Transactional annotation to prevent it of rolling back like:

@Transactional(rollbackFor=MyException.class, noRollbackFor=MyException2.class)

#!/bin/bash
message="some text"
message="$message add some more"

echo $message

some text add some more

I strongly prefer simply using Microsoft Visual Studio and writing a native Win32 app.

For a GUI as simple as the one that you describe, you could simply create a Dialog Box and use it as your main application window. The default application created by the Win32 Project wizard in Visual Studio actually pops a window, so you can replace that window with your Dialog Box and replace the WndProc with a similar (but simpler) DialogProc.

The question, then, is one of tools and cost. The Express Edition of Visual C++ does everything you want except actually create the Dialog Template resource. For this, you could either code it in the RC file by hand or in memory by hand. Related SO question: Windows API Dialogs without using resource files.

Or you could try one of the free resource editors that others have recommended.

Finally, the Visual Studio 2008 Standard Edition is a costlier option but gives you an integrated resource editor.

You should never use select(), or text(), or radio() etc.; it's terrible practice. You should use input():

$form->input('tree_id', array('options' => $trees));

Then in the controller:

$this->data['Leaf']['tree_id'] = $id;

What about using a HashMap? Insertion, deletion, and retrieval are all O(1) operations. If you wanted to sort everything, you could grab a List of the values in the Map and run them through an O(n log n) sorting algorithm.

edit

A quick search has found LinkedHashMap, which maintains insertion order of your keys. It's not an exact solution, but it's pretty close.

Assuming the objects in your source array have an id property...

var $local_source = [
    { id: 1, value: "c++" },
    { id: 2, value: "java" },
    { id: 3, value: "php" },
    { id: 4, value: "coldfusion" },
    { id: 5, value: "javascript" },
    { id: 6, value: "asp" },
    { id: 7, value: "ruby" }];

Getting hold of the current instance and inspecting its selectedItem property will allow you to retrieve the properties of the currently selceted item. In this case alerting the id of the selected item.

$('#button').click(function() {
    alert($("#txtAllowSearch").autocomplete("instance").selectedItem.id;
});
