Be sure to include the Key in the imports...

const {Builder, By, logging, until, Key} = require('selenium-webdriver');

searchInput.sendKeys(Key.ENTER) worked great for me

1. Edit the file /etc/postgresql/<version>/main/pg_hba.conf and find the following line:

   local   all             postgres                                md5
   

2. Edit the line and change md5 at the end to trust and save the file

3. Reload the postgresql service

   $ sudo service postgresql reload
   

4. This will load the configuration files. Now you can modify the postgres user by logging into the psql shell

   $ psql -U postgres
   

5. Update the postgres user's password

   alter user postgres with password 'secure-passwd-here';
   

6. Edit the file /etc/postgresql/<version>/main/pg_hba.conf and change trust back to md5 and save the file

7. Reload the postgresql service

   $ sudo service postgresql reload
   

8. Verify that the password change is working

   $ psql -U postgres -W
   

You can define a getter on Array.prototype:

if (!Array.prototype.hasOwnProperty("last")) {_x000D_
  Object.defineProperty(Array.prototype, "last", {_x000D_
    get() {_x000D_
      return this[this.length - 1];_x000D_
    }_x000D_
  });_x000D_
}_x000D_
_x000D_
console.log([9, 8, 7, 6].last); // => 6

As you can see, access doesn't look like a function call; the getter function is called internally.

To show the commits in oldbranch but not in newbranch:

git log newbranch..oldbranch

To show the diff by these commits (note there are three dots):

git diff newbranch...oldbranch

Here is the doc with a diagram illustration https://git-scm.com/book/en/v2/Git-Tools-Revision-Selection#Commit-Ranges

In adition to the other answers mentioning the Tasks view:

It is also possible to filter the Tasks that are listed to only show the TODOs that contain the text // TODO Auto-generated method stub.

To achieve this you can click on the Filters... button in the top right of the Tasks View and define custom filters like this:

This way it's a bit easier and faster to find only some of the TODOs in the project in the Tasks View, and you don't have to search for the text in all files using the eclipse search tool (which can take quite some time).

I know this is an old issue but I just had to do this for a project at work, and I am very surprised that nobody has thought of this solution yet: Just open the .pdf with Microsoft word.

The code is a lot easier to work with when you are trying to extract data from a .docx because it opens in Microsoft Word. Excel and Word play well together because they are both Microsoft programs. In my case, the file of question had to be a .pdf file. Here's the solution I came up with:

1. Choose the default program to open .pdf files to be Microsoft Word
2. The first time you open a .pdf file with word, a dialogue box pops up claiming word will need to convert the .pdf into a .docx file. Click the check box in the bottom left stating "do not show this message again" and then click OK.
3. Create a macro that extracts data from a .docx file. I used MikeD's Code as a resource for this.
4. Tinker around with the MoveDown, MoveRight, and Find.Execute methods to fit the need of your task.

Yes you could just convert the .pdf file to a .docx file but this is a much simpler solution in my opinion.

According to this site add

CONFIG += c++11

to your .pro file (see at the bottom of that web page). It requires Qt 5.

The other answers, suggesting

QMAKE_CXXFLAGS += -std=c++11 (or QMAKE_CXXFLAGS += -std=c++0x)

also work with Qt 4.8 and gcc / clang.

A lot of people are saying that once you get to the size where speed is actually a concern that HashSet<T> will always beat List<T>, but that depends on what you are doing.

Let's say you have a List<T> that will only ever have on average 5 items in it. Over a large number of cycles, if a single item is added or removed each cycle, you may well be better off using a List<T>.

I did a test for this on my machine, and, well, it has to be very very small to get an advantage from List<T>. For a list of short strings, the advantage went away after size 5, for objects after size 20.

public class MainActivity extends AppCompatActivity implements View.OnClickListener

Whenever you use (this) on click events, your main activity has to implement ocClickListener. Android Studio does it for you, press alt+enter on the 'this' word.

Use attribute name.

Here you can find the solution ("Use iframe as a Target for a Link"): http://www.w3schools.com/html/html_iframe.asp

If you are using C99 just include stdint.h. BTW, the 64bit types are there iff the processor supports them.

Edit: seems I was wrong in assuming you could not get the element. As others have posted here, you can get it with:

$('#element').get(0);

I have verified this actually returns the DOM element that was matched.

USE THIS

I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.

http://blog.summitcloud.com/2010/01/multivalue-parameters-with-stored-procedures-in-ssrs-sql/

I hope this helps people because it was exactly what I was looking for

Also, You can write all inline, direct at html code:

<input type="file" id="imgupload">
<a href="#" onclick="$('#imgupload').trigger('click'); return false;">Upload file</a>

return false; - will be useful to decline anchor action after link was clicked.

Could you use jQuery, since it's cross-browser compatible?

function isOnScreen(element)
{
    var curPos = element.offset();
    var curTop = curPos.top;
    var screenHeight = $(window).height();
    return (curTop > screenHeight) ? false : true;
}

And then call the function using something like:

if(isOnScreen($('#myDivId'))) { /* Code here... */ };

Here is an example that works:

MatchPassword(AC: FormControl) {
  let dataForm = AC.parent;
  if(!dataForm) return null;

  var newPasswordRepeat = dataForm.get('newPasswordRepeat');
  let password = dataForm.get('newPassword').value;
  let confirmPassword = newPasswordRepeat.value;

  if(password != confirmPassword) {
    /* for newPasswordRepeat from current field "newPassword" */
    dataForm.controls["newPasswordRepeat"].setErrors( {MatchPassword: true} );
    if( newPasswordRepeat == AC ) {
      /* for current field "newPasswordRepeat" */
      return {newPasswordRepeat: {MatchPassword: true} };
    }
  } else {
    dataForm.controls["newPasswordRepeat"].setErrors( null );
  }
  return null;
}

createForm() {
  this.dataForm = this.fb.group({
    password: [ "", Validators.required ],
    newPassword: [ "", [ Validators.required, Validators.minLength(6), this.MatchPassword] ],
    newPasswordRepeat: [ "", [Validators.required, this.MatchPassword] ]
  });
}

no javascript or third party 'tools' necessary, use this:

<iframe src="https://www.google.com/maps/embed/v1/place?key=<YOUR API KEY>&q=71.0378379,-110.05995059999998"></iframe>

the place parameter provides the marker

there are a few options for the format of the 'q' parameter

make sure you have Google Maps Embed API and Static Maps API enabled in your APIs, or google will block the request

We just released preview driver for Node.JS for SQL Server connectivity. You can find it here: Introducing the Microsoft Driver for Node.JS for SQL Server.

The driver supports callbacks (here, we're connecting to a local SQL Server instance):

// Query with explicit connection
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server=(local);Database=AdventureWorks2012;Trusted_Connection={Yes}";

sql.open(conn_str, function (err, conn) {
    if (err) {
        console.log("Error opening the connection!");
        return;
    }
    conn.queryRaw("SELECT TOP 10 FirstName, LastName FROM Person.Person", function (err, results) {
        if (err) {
            console.log("Error running query!");
            return;
        }
        for (var i = 0; i < results.rows.length; i++) {
            console.log("FirstName: " + results.rows[i][0] + " LastName: " + results.rows[i][1]);
        }
    });
});

Alternatively, you can use events (here, we're connecting to SQL Azure a.k.a Windows Azure SQL Database):

// Query with streaming
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server={tcp:servername.database.windows.net,1433};UID={username};PWD={Password1};Encrypt={Yes};Database={databasename}";

var stmt = sql.query(conn_str, "SELECT FirstName, LastName FROM Person.Person ORDER BY LastName OFFSET 0 ROWS FETCH NEXT 10 ROWS ONLY");
stmt.on('meta', function (meta) { console.log("We've received the metadata"); });
stmt.on('row', function (idx) { console.log("We've started receiving a row"); });
stmt.on('column', function (idx, data, more) { console.log(idx + ":" + data);});
stmt.on('done', function () { console.log("All done!"); });
stmt.on('error', function (err) { console.log("We had an error :-( " + err); });

If you run into any problems, please file an issue on Github: https://github.com/windowsazure/node-sqlserver/issues

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Pool

• Pooling Mechanism is the way of creating the Objects in advance. When a class is loaded.
• It improves the application performance [By re using same object's to perform any action on Object-Data] & memory [allocating and de-allocating many objects creates a significant memory management overhead].
• Object clean-up is not required as we are using same Object, reducing the Garbage collection load.

« Pooling [ Object pool, String Constant Pool, Thread Pool, Connection pool]

String Constant pool

• String literal pool maintains only one copy of each distinct string value. which must be immutable.
• When the intern method is invoked, it check object availability with same content in pool using equals method. « If String-copy is available in the Pool then returns the reference. « Otherwise, String object is added to the pool and returns the reference.

Example: String to verify Unique Object from pool.

public class StringPoolTest {
    public static void main(String[] args) { // Integer.valueOf(), String.equals()
        String eol = System.getProperty("line.separator"); //java7 System.lineSeparator();

        String s1 = "Yash".intern();
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s1, s1.hashCode(), System.identityHashCode(s1));
        String s2 = "Yas"+"h".intern();
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s2, s2.hashCode(), System.identityHashCode(s2));
        String s3 = "Yas".intern()+"h".intern();
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s3, s3.hashCode(), System.identityHashCode(s3));
        String s4 = "Yas"+"h";
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s4, s4.hashCode(), System.identityHashCode(s4));
    }
}

Connection pool using Type-4 Driver using 3rd party libraries[ DBCP2, c3p0, Tomcat JDBC]

Type 4 - The Thin driver converts JDBC calls directly into the vendor-specific database protocol Ex[Oracle - Thick, MySQL - Quora]. wiki

In Connection pool mechanism, when the class is loaded it get's the physical JDBC connection objects and provides a wrapped physical connection object to user. PoolableConnection is a wrapper around the actual connection.

• getConnection() pick one of the free wrapped-connection form the connection objectpool and returns it.
• close() instead of closing it returns the wrapped-connection back to pool.

I had a similar issue trying to fix the item size to fit the background image width. This worked (at least with Firefox 35) for me :

.navcontainer-top li
{
  display: inline-block;
  background: url("../images/nav-button.png") no-repeat;
  width: 117px;
  height: 26px;
}

String s = "test string (67)";

System.out.println(s.substring(s.indexOf("(")+1,s.indexOf(")")));

It can be accomplished like this docs

$('input').trigger("keydown", {which: 50});

The easiest way to compute the correct mouse click or mouse move position on a canvas event is to use this little equation:

canvas.addEventListener('click', event =>
{
    let bound = canvas.getBoundingClientRect();

    let x = event.clientX - bound.left - canvas.clientLeft;
    let y = event.clientY - bound.top - canvas.clientTop;

    context.fillRect(x, y, 16, 16);
});

If the canvas has padding-left or padding-top, subtract x and y via:

x -= parseFloat(style['padding-left'].replace('px'));
y -= parseFloat(style['padding-top'].replace('px'));

You could reference controls inside the master page this way:

void Page_Load()
{
    ContentPlaceHolder cph;
    Literal lit;

    cph = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");

    if (cph != null) {
        lit = (Literal) cph.FindControl("Literal1");
        if (lit != null) {
            lit.Text = "Some <b>HTML</b>";
        }
    }

}

In this example you have to put a Literal control in your ContentPlaceholder.

If your are not in a session you can just nextval('you_sequence_name') and it's just fine.

Since these are member functions, call it as a member function on the instance, self.

def isNear(self, p):
    self.distToPoint(p)
    ...

Most of the time I just wish to have all placeholders equal to the verbose name of the field defined in my models

I've added a mixin to easily do this to any form that I create,

class ProductForm(PlaceholderMixin, ModelForm):
    class Meta:
        model = Product
        fields = ('name', 'description', 'location', 'store')

And

class PlaceholderMixin:
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        field_names = [field_name for field_name, _ in self.fields.items()]
        for field_name in field_names:
            field = self.fields.get(field_name)
            field.widget.attrs.update({'placeholder': field.label})

Unfortunately, there is no equivalent for Safari and the argument --disable-web-security doesn't work with Safari.

If you have access to the server side application, you can modify the https response headers to allow access. Mainly the Access-Control-Allow-Origin header. Modifying it will allow Safari to access the resource. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Access-Control-Allow-Origin for more information on the response headers that will help.

You need to correctly separate static data from instance data. In your code, onLoan and setLoanItem() are instance members. If you want to reference/call them you must do so via an instance. So you either want

public void loanItem() {
    this.media.setLoanItem("Yes");
}

or

public void loanItem(Media object) {
    object.setLoanItem("Yes");
}

depending on how you want to pass that instance around.

If you want to use a high-level API, that hides a lot of the JDBC complexity around database schema metadata, take a look at this article: http://www.devx.com/Java/Article/32443/1954

You can also add your own suggestion.

Open this path:

C:\Program Files\Notepad++\plugins\APIs

And open the XML file of the language, such as php.xml. Here suppose, you would like to add addcslashes, so just add this XML code.

<KeyWord name="addcslashes" func="yes">
    <Overload retVal="void">
        <Param name="void"/>
    </Overload>
</KeyWord>

If you want to do the shortcut way :) :

','.join([str(word) for word in wordList])

But if you want to show off with logic :) :

wordList = ['USD', 'EUR', 'JPY', 'NZD', 'CHF', 'CAD']
stringText = ''

for word in wordList:
    stringText += word + ','

stringText = stringText[:-2]   # get rid of last comma
print(stringText)

It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:

char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);

Without the fflush(), if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar() peeks the "a", but the "\n" remains in the buffer, so the next fgets() will find it and return an empty string without even waiting for user input.

However, note that this use of fflush() is unportable. I've tested right now on a Linux machine, and it does not work, for example.

You can use ISNULL().

SELECT ISNULL(SUM(Price), 0) AS TotalPrice 
FROM Inventory
WHERE (DateAdded BETWEEN @StartDate AND @EndDate)

That should do the trick.

You're right that .import is the way to go, but that's a command from the SQLite3.exe shell. A lot of the top answers to this question involve native python loops, but if your files are large (mine are 10^6 to 10^7 records), you want to avoid reading everything into pandas or using a native python list comprehension/loop (though I did not time them for comparison).

For large files, I believe the best option is to create the empty table in advance using sqlite3.execute("CREATE TABLE..."), strip the headers from your CSV files, and then use subprocess.run() to execute sqlite's import statement. Since the last part is I believe the most pertinent, I will start with that.

subprocess.run()

from pathlib import Path
db_name = Path('my.db').resolve()
csv_file = Path('file.csv').resolve()
result = subprocess.run(['sqlite3',
                         str(db_name),
                         '-cmd',
                         '.mode csv',
                         '.import '+str(csv_file).replace('\\','\\\\')
                                 +' <table_name>'],
                        capture_output=True)

Explanation
From the command line, the command you're looking for is sqlite3 my.db -cmd ".mode csv" ".import file.csv table". subprocess.run() runs a command line process. The argument to subprocess.run() is a sequence of strings which are interpreted as a command followed by all of it's arguments.

• sqlite3 my.db opens the database
• -cmd flag after the database allows you to pass multiple follow on commands to the sqlite program. In the shell, each command has to be in quotes, but here, they just need to be their own element of the sequence
• '.mode csv' does what you'd expect
• '.import '+str(csv_file).replace('\\','\\\\')+' <table_name>' is the import command.
  Unfortunately, since subprocess passes all follow-ons to -cmd as quoted strings, you need to double up your backslashes if you have a windows directory path.

Stripping Headers

Not really the main point of the question, but here's what I used. Again, I didn't want to read the whole files into memory at any point:

with open(csv, "r") as source:
    source.readline()
    with open(str(csv)+"_nohead", "w") as target:
        shutil.copyfileobj(source, target)

Here are my 2 cents on different options for completing this:

Third party tools: Probably the easiest way to get the job done is to create an empty database on lower version and then use third party tools to read the backup and synchronize new newly created database with the backup.

Red gate is one of the most popular but there are many others like ApexSQL Diff , ApexSQL Data Diff, Adept SQL, Idera …. All of these are premium tools but you can get the job done in trial mode ;)

Generating scripts: as others already mentioned you can always script structure and data using SSMS but you need to take into consideration the order of execution. By default object scripts are not ordered correctly and you’ll have to take care of the dependencies. This may be an issue if database is big and has a lot of objects.

Import and export wizard: This is not an ideal solution as it will not restore all objects but only data tables but you can consider it for quick and dirty fixes when it’s needed.

I think in different situations different method is better. For example, if you should process the return value before return, you should have one point of exit. But in other situations, it is more comfortable to use several returns.

One note. If you should process the return value before return in several situations, but not in all, the best solutions (IMHO) to define a method like ProcessVal and call it before return:

var retVal = new RetVal();

if(!someCondition)
    return ProcessVal(retVal);

if(!anotherCondition)
   return retVal;

This is about generating data, and so is more properly done from the model. Imagine if you ever wanted to change the way data is displayed in the drop-down box, say add a surname or something. You'd have to find every drop-down box and change the arrayHelper. I use a function in my models to return the data for a dropdown, so I don't have to repeat code in views. It also has the advantage that I can specify filter here and have them apply to every dropdown created from this model;

/* Model Standard.php */

public function getDropdown(){
      return ArrayHelper::map(self::find()->all(), 's_id', 'name'));
}

You can use this in your view file like this;

echo $form->field($model, 'attribute')
        ->dropDownList(
            $model->dropDown
        );

To make it short, use npm link jade in your app directory.

[1-9]\.\d{1,2}|0\.((0?[1-9])|([1-9]0?)){1,2}\b

If you dont want to query for it just create an entity, and then delete it.

Customer customer  = new Customer() {  Id = 1   } ; 
context.AttachTo("Customers", customer);
context.DeleteObject(customer);
context.Savechanges();

As @Vadzim said, in IntelliJ or Android Studio, you just have to do the following to get java code from kotlin:

1. Menu > Tools > Kotlin > Show Kotlin Bytecode
2. Click on the Decompile button
3. Copy the java code

Update:

With a recent version (1.2+) of the Kotlin plugin you also can directly do Menu > Tools > Kotlin -> Decompile Kotlin to Java.

The following worked for me. Just add the following snippet:

dexOptions {
        javaMaxHeapSize "4g"
}

To your build.gradle:

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1'

    defaultConfig {
        applicationId "yourpackage"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        multiDexEnabled true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {

    }

    dexOptions {
        javaMaxHeapSize "4g"
    }
}

Something fairly ODBC compliant if needed might be the following:

select ifnull(repeat('0', 5 - (floor(log10(FIELD_NAME)) + 1)), '')
        + cast (FIELD as varchar(10))
  from TABLE_NAME

This bases on the fact that the amount of digits for a base-10 number can be found by the integral component of its log. From this we can subtract it from the desired padding width. Repeat will return null for values under 1 so we need ifnull.

open(filename,'r')   #2nd argument is r and not w

will open the file or give an error if it doesn't exist. If there's an error, then you can try to write to the path, if you can't then you get a second error

try:
    open(filename,'r')
    return True
except IOError:
    try:
        open(filename, 'w')
        return True
    except IOError:
        return False

Also have a look here about permissions on windows

We used DBVisualizer for that.

Description: The references graph is a great feature as it automatically renders all primary/foreign key mappings (also called referential integrity constraints) in a graph style. The table nodes and relations are layed out automatically, with a number of layout modes available. The resulting graph is unique as it displays all information in an optimal and readable layout. from its site

You can either use onclick inside the button to ensure the event is preserved, or else attach the button click handler by finding the button after it is inserted. The test.html() call will not serialize the event.

I had an issue with blob url hrefs. So, with a reference to the iframe, I just produced an url from the iframe's src attribute:

    const iframeReference = document.getElementById("iframe_id");
    const iframeUrl = iframeReference ? new URL(iframeReference.src) : undefined;
    if (iframeUrl) {
        console.log("Voila: " + iframeUrl);
    } else {
        console.warn("iframe with id iframe_id not found");
    }

The default value of any Object, such as Boolean, is null.

The default value for a boolean is false.

Note: Every primitive has a wrapper class. Every wrapper uses a reference which has a default of null. Primitives have different default values:

boolean -> false

byte, char, short, int, long -> 0

float, double -> 0.0

Note (2): void has a wrapper Void which also has a default of null and is it's only possible value (without using hacks).

There are no implicit copies made in java via the assignment operator. Variables contain a reference value (pointer) and when you use = you're only coping that value.

In order to preserve the contents of myTempObject you would need to make a copy of it.

This can be done by creating a new ArrayList using the constructor that takes another ArrayList:

ArrayList<Object> myObject = new ArrayList<Object>(myTempObject);

Edit: As Bohemian points out in the comments below, is this what you're asking? By doing the above, both ArrayLists (myTempObject and myObject) would contain references to the same objects. If you actually want a new list that contains new copies of the objects contained in myTempObject then you would need to make a copy of each individual object in the original ArrayList

I had the same problem and all the solutions mentioned here didn't work out for me.

After uninstalling the "Productivity Power Tools 2013" extension, the performance was back to normal.

I made a command line tool to activate the profiler activity and see the logs in a "tail"able way: "mongotail".

But the more interesting feature (also like tail) is to see the changes in "real time" with the -f option, and occasionally filter the result with grep to find a particular operation.

See documentation and installation instructions in: https://github.com/mrsarm/mongotail

One of the simplest way is to use flatten(), like this example :

 import numpy as np

 batch_y =train_output.iloc[sample, :]
 batch_y = np.array(batch_y).flatten()

My array it was like this :

    0
0   6
1   6
2   5
3   4
4   3
.
.
.

After using flatten():

array([6, 6, 5, ..., 5, 3, 6])

It's also the solution of errors of this type :

Cannot feed value of shape (100, 1) for Tensor 'input/Y:0', which has shape '(?,)' 

Maybe the string keyword confused you, as it looks exactly like any other value type declaration, but it is actually an alias to System.String as explained in this question.
Also the dark blue color in Visual Studio and the lowercase first letter may mislead into thinking it is a struct.

You can use

String.PadLeft()
String.Format()

I know it is a very old question, but better update it with new information.

You can install service by using sc command:

InstallService.bat:

@echo OFF
echo Stopping old service version...
net stop "[YOUR SERVICE NAME]"
echo Uninstalling old service version...
sc delete "[YOUR SERVICE NAME]"

echo Installing service...
rem DO NOT remove the space after "binpath="!
sc create "[YOUR SERVICE NAME]" binpath= "[PATH_TO_YOUR_SERVICE_EXE]" start= auto
echo Starting server complete
pause

With SC, you can do a lot more things as well: uninstalling the old service (if you already installed it before), checking if service with same name exists... even set your service to autostart.

One of many references: creating a service with sc.exe; how to pass in context parameters

I have done by both this way & InstallUtil. Personally I feel that using SC is cleaner and better for your health.

Short and easy version:

1. First create this abstract class

public abstract class HorizontalSwipeListener implements View.OnTouchListener {

    private float firstX;
    private int minDistance;

    HorizontalSwipeListener(int minDistance) {
        this.minDistance = minDistance;
    }

    abstract void onSwipeRight();

    abstract void onSwipeLeft();

    @Override
    public boolean onTouch(View view, MotionEvent event) {

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                firstX = event.getX();
                return true;
            case MotionEvent.ACTION_UP:
                float secondX = event.getX();
                if (Math.abs(secondX - firstX) > minDistance) {
                    if (secondX > firstX) {
                        onSwipeLeft();
                    } else {
                        onSwipeRight();
                    }
                }
                return true;
        }
        return view.performClick();
    }

}

2.Then create a concrete class implementing what you need:

public class SwipeListener extends HorizontalSwipeListener {

    public SwipeListener() {
        super(200);
    }

    @Override
    void onSwipeRight() {
        System.out.println("right");
    }

    @Override
    void onSwipeLeft() {
        System.out.println("left");
    }

}

simply change <div> to <tbody>

<table id="authenticationSetting" style="display: none">
  <tbody id="authenticationOuterIdentityBlock" style="display: none;">
    <tr>
      <td class="orionSummaryHeader">
        <orion:message key="policy.wifi.enterprise.authentication.outeridentitity" />:</td>
      <td class="orionSummaryColumn">
        <orion:textbox id="authenticationOuterIdentity" size="30" />
      </td>
    </tr>
  </tbody>
</table>

Somewhat similar to your original attempt, but more Pythonic, is to use Python's standard negative-indexing convention to count backwards from the end:

df[df.columns[-1]]

>>> d = {u"a": u"b", u"c": u"d"}
>>> d
{u'a': u'b', u'c': u'd'}
>>> import json
>>> import yaml
>>> d = {u"a": u"b", u"c": u"d"}
>>> yaml.safe_load(json.dumps(d))
{'a': 'b', 'c': 'd'}

I built a general method for that with following features:

• returning "not modified" if the file hasn't been modified locally, a Status.NOT_MODIFIED is sent to the caller. Uses Apache Commons Lang
• using a file stream object instead of reading the file itself

Here the code:

import org.apache.commons.lang3.time.DateUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

private static final Logger logger = LoggerFactory.getLogger(Utils.class);

@GET
@Path("16x16")
@Produces("image/png")
public Response get16x16PNG(@HeaderParam("If-Modified-Since") String modified) {
    File repositoryFile = new File("c:/temp/myfile.png");
    return returnFile(repositoryFile, modified);
}

/**
 * 
 * Sends the file if modified and "not modified" if not modified
 * future work may put each file with a unique id in a separate folder in tomcat
 *   * use that static URL for each file
 *   * if file is modified, URL of file changes
 *   * -> client always fetches correct file 
 * 
 *     method header for calling method public Response getXY(@HeaderParam("If-Modified-Since") String modified) {
 * 
 * @param file to send
 * @param modified - HeaderField "If-Modified-Since" - may be "null"
 * @return Response to be sent to the client
 */
public static Response returnFile(File file, String modified) {
    if (!file.exists()) {
        return Response.status(Status.NOT_FOUND).build();
    }

    // do we really need to send the file or can send "not modified"?
    if (modified != null) {
        Date modifiedDate = null;

        // we have to switch the locale to ENGLISH as parseDate parses in the default locale
        Locale old = Locale.getDefault();
        Locale.setDefault(Locale.ENGLISH);
        try {
            modifiedDate = DateUtils.parseDate(modified, org.apache.http.impl.cookie.DateUtils.DEFAULT_PATTERNS);
        } catch (ParseException e) {
            logger.error(e.getMessage(), e);
        }
        Locale.setDefault(old);

        if (modifiedDate != null) {
            // modifiedDate does not carry milliseconds, but fileDate does
            // therefore we have to do a range-based comparison
            // 1000 milliseconds = 1 second
            if (file.lastModified()-modifiedDate.getTime() < DateUtils.MILLIS_PER_SECOND) {
                return Response.status(Status.NOT_MODIFIED).build();
            }
        }
    }        
    // we really need to send the file

    try {
        Date fileDate = new Date(file.lastModified());
        return Response.ok(new FileInputStream(file)).lastModified(fileDate).build();
    } catch (FileNotFoundException e) {
        return Response.status(Status.NOT_FOUND).build();
    }
}

/*** copied from org.apache.http.impl.cookie.DateUtils, Apache 2.0 License ***/

Note that the Locale switching does not seem to be thread-safe. I think, it's better to switch the locale globally. I am not sure about the side-effects though...

Try this it might solve your problem.

Css:

.item{padding-top:1px;}

.jobs .item:hover {
    background: #e1e1e1;
    border-top: 1px solid #d0d0d0;
    padding-top:0;
}

HTML:

<div class="jobs">
    <div class="item">
        content goes here
    </div>
</div>

You can try to set_time_limit(n). However, if your PHP setup is running in safe mode, you can only change it from the php.ini file.

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );

Using seeds.rb file or FactoryBot is great, but these are respectively great for fixed data structures and testing.

The seedbank gem might give you more control and modularity to your seeds. It inserts rake tasks and you can also define dependencies between your seeds. Your rake task list will have these additions (e.g.):

rake db:seed                    # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/ENVIRONMENT/*.seeds.rb. ENVIRONMENT is the current environment in Rails.env.
rake db:seed:bar                # Load the seed data from db/seeds/bar.seeds.rb
rake db:seed:common             # Load the seed data from db/seeds.rb and db/seeds/*.seeds.rb.
rake db:seed:development        # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/development/*.seeds.rb.
rake db:seed:development:users  # Load the seed data from db/seeds/development/users.seeds.rb
rake db:seed:foo                # Load the seed data from db/seeds/foo.seeds.rb
rake db:seed:original           # Load the seed data from db/seeds.rb

The difference is:
- orphanRemoval = true: "Child" entity is removed when it's no longer referenced (its parent may not be removed).
- CascadeType.REMOVE: "Child" entity is removed only when its "Parent" is removed.

Here is a trick though. You can map the Ctrl+Z keys. This can be achieved by editing the .vimrc file. Add the following lines in the '.vimrc` file.

nnoremap <c-z> :u<CR>      " Avoid using this**
inoremap <c-z> <c-o>:u<CR>

This may not the a preferred way, but can be used.

** Ctrl+Z is used in Linux to suspend the ongoing program/process.

The above instantiates an anonymous inner class which is a subclass of the my abstract class. It's not strictly equivalent to instantiating the abstract class itself. OTOH, every subclass instance is an instance of all its super classes and interfaces, so most abstract classes are indeed instantiated by instantiating one of their concrete subclasses.

If the interviewer just said "wrong!" without explaining, and gave this example, as a unique counterexample, I think he doesn't know what he's talking about, though.

If you don't want to use a download manager then you can use this code

webView.setDownloadListener(new DownloadListener() {

            @Override
            public void onDownloadStart(String url, String userAgent, String contentDisposition
                    , String mimetype, long contentLength) {

                String fileName = URLUtil.guessFileName(url, contentDisposition, mimetype);

                try {
                    String address = Environment.getExternalStorageDirectory().getAbsolutePath() + "/"
                            + Environment.DIRECTORY_DOWNLOADS + "/" +
                            fileName;
                    File file = new File(address);
                    boolean a = file.createNewFile();

                    URL link = new URL(url);
                    downloadFile(link, address);

                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });

 public void downloadFile(URL url, String outputFileName) throws IOException {

        try (InputStream in = url.openStream();
             ReadableByteChannel rbc = Channels.newChannel(in);
             FileOutputStream fos = new FileOutputStream(outputFileName)) {
            fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
        }
           // do your work here

    }

This will download files in the downloads folder in phone storage. You can use threads if you want to download that in the background (use thread.alive() and timer class to know the download is complete or not). This is useful when we download small files, as you can do the next task just after the download.

Select date1 - (date2 - 1) * 24 * 60 *60 * 1000 from Table;

You are building a DataGridView on the fly and set the DataSource for it. That's good, but then do you add the DataGridView to the Controls collection of the hosting form?

this.Controls.Add(dataGridView1);

By the way the code is a bit confused

String connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\\Tables.accdb;Persist Security Info=True";
string sql  = "SELECT Clients  FROM Tables";
using(OleDbConnection conn = new OleDbConnection(connection))
{
     conn.Open();
     DataSet ds = new DataSet();
     DataGridView dataGridView1 = new DataGridView();
     using(OleDbDataAdapter adapter = new OleDbDataAdapter(sql,conn))
     {
         adapter.Fill(ds);
         dataGridView1.DataSource = ds;
         // Of course, before addint the datagrid to the hosting form you need to 
         // set position, location and other useful properties. 
         // Why don't you create the DataGrid with the designer and use that instance instead?
         this.Controls.Add(dataGridView1);
     }
}

EDIT After the comments below it is clear that there is a bit of confusion between the file name (TABLES.ACCDB) and the name of the table CLIENTS.
The SELECT statement is defined (in its basic form) as

 SELECT field_names_list FROM _tablename_

so the correct syntax to use for retrieving all the clients data is

 string sql  = "SELECT * FROM Clients";

where the * means -> all the fields present in the table

You can loop all of the array and add into ArrayList:

ArrayList<String> files = new ArrayList<String>(filesOrig.length);
for(String file: filesOrig) {
    files.add(file);
}

Or use Arrays.asList(T... a) to do as the comment posted.

Most people are using gson : check this

Gson gson = new Gson();
String json = gson.toJson(myObj);

We implemented two versions of this, one a simple multi thread pool that can execute many types of callables, making our lives much easier and the second version that uses processes, which is less flexible in terms of callables and requires and extra call to dill.

Setting frozen_pool to true will freeze execution until finish_pool_queue is called in either class.

In simple, using Comparator and Collection you can sort like below in reversal order using JAVA 8

import java.util.stream.Collectors;

Arrays.asList(files).stream()
    .sorted(Comparator.comparing(File::getLastModified).reversed())
    .collect(Collectors.toList());

Some Theory

$ is the name of a function like any other name you give to a function. Anyone can create a function in JavaScript and name it $ as shown below:

$ = function() { 
        alert('I am in the $ function');
    }

JQuery is a very famous JavaScript library and they have decided to put their entire framework inside a function named jQuery. To make it easier for people to use the framework and reduce typing the whole word jQuery every single time they want to call the function, they have also created an alias for it. That alias is $. Therefore $ is the name of a function. Within the jQuery source code, you can see this yourself:

window.jQuery = window.$ = jQuery;

Answer To Your Question

So what is $(function() { });?

Now that you know that $ is the name of the function, if you are using the jQuery library, then you are calling the function named $ and passing the argument function() {} into it. The jQuery library will call the function at the appropriate time. When is the appropriate time? According to jQuery documentation, the appropriate time is once all the DOM elements of the page are ready to be used.

The other way to accomplish this is like this:

$(document).ready(function() { });

As you can see this is more verbose so people prefer $(function() { })

So the reason why some functions cannot be called, as you have noticed, is because those functions do not exist yet. In other words the DOM has not loaded yet. But if you put them inside the function you pass to $ as an argument, the DOM is loaded by then. And thus the function has been created and ready to be used.

Another way to interpret $(function() { }) is like this:

Hey $ or jQuery, can you please call this function I am passing as an argument once the DOM has loaded?

from joblib import Parallel, delayed
import multiprocessing

inputs = range(10) 
def processInput(i):
    return i * i

num_cores = multiprocessing.cpu_count()

results = Parallel(n_jobs=num_cores)(delayed(processInput)(i) for i in inputs)
print(results)

The above works beautifully on my machine (Ubuntu, package joblib was pre-installed, but can be installed via pip install joblib).

Taken from https://blog.dominodatalab.com/simple-parallelization/

In your configuration you have 2 PropertySourcesPlaceholderConfigurer instances.

applicationContext.xml

<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
    <property name="environment">
        <bean class="org.springframework.web.context.support.StandardServletEnvironment"/>
    </property>
</bean>

infraContext.xml

<context:property-placeholder location="classpath:context-core.properties"/>

By default a PlaceholderConfigurer is going to fail-fast, so if a placeholder cannot be resolved it will throw an exception. The instance from the applicationContext.xml file has no properties and as such will fail on all placeholders.

Solution: Remove the one from applicationContext.xml as it doesn't add anything it only breaks things.

If you want the k-th bit of n, then do

(n & ( 1 << k )) >> k

Here we create a mask, apply the mask to n, and then right shift the masked value to get just the bit we want. We could write it out more fully as:

    int mask =  1 << k;
    int masked_n = n & mask;
    int thebit = masked_n >> k;

You can read more about bit-masking here.

Here is a program:

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

int *get_bits(int n, int bitswanted){
  int *bits = malloc(sizeof(int) * bitswanted);

  int k;
  for(k=0; k<bitswanted; k++){
    int mask =  1 << k;
    int masked_n = n & mask;
    int thebit = masked_n >> k;
    bits[k] = thebit;
  }

  return bits;
}

int main(){
  int n=7;

  int  bitswanted = 5;

  int *bits = get_bits(n, bitswanted);

  printf("%d = ", n);

  int i;
  for(i=bitswanted-1; i>=0;i--){
    printf("%d ", bits[i]);
  }

  printf("\n");
}

in Intellij, what resolved the issue for me was to open the Maven right side toolbar

choose "Clean" , "install" and hit the "Play" button:

You can have it go to the same page without specifying the url:

window.open('?','_self');

is compares identity. A string will never be identical to a not-string.

== is equality. But a string will never be equal to either True or False.

You want neither.

You can also surround the output with str(). I had this same problem because my model had the following (as a simplified example):

def __str__(self):
    return self.pressid

Where pressid was an IntegerField type object. Django (and python in general) expects a string for a str function, so returning an integer causes this error to be thrown.

def __str__(self):
    return str(self.pressid)

That solved the problems I was encountering on the Django management side of the house. Hope it helps with yours.

In addition to excellent answers already provided, there are some cases where explicit implementation is REQUIRED for the compiler to be able to figure out what is required. Take a look at IEnumerable<T> as a prime example that will likely come up fairly often.

Here's an example:

public abstract class StringList : IEnumerable<string>
{
    private string[] _list = new string[] {"foo", "bar", "baz"};

    // ...

    #region IEnumerable<string> Members
    public IEnumerator<string> GetEnumerator()
    {
        foreach (string s in _list)
        { yield return s; }
    }
    #endregion

    #region IEnumerable Members
    IEnumerator IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator();
    }
    #endregion
}

Here, IEnumerable<string> implements IEnumerable, hence we need to too. But hang on, both the generic and the normal version both implement functions with the same method signature (C# ignores return type for this). This is completely legal and fine. How does the compiler resolve which to use? It forces you to only have, at most, one implicit definition, then it can resolve whatever it needs to.

ie.

StringList sl = new StringList();

// uses the implicit definition.
IEnumerator<string> enumerableString = sl.GetEnumerator();
// same as above, only a little more explicit.
IEnumerator<string> enumerableString2 = ((IEnumerable<string>)sl).GetEnumerator();
// returns the same as above, but via the explicit definition
IEnumerator enumerableStuff = ((IEnumerable)sl).GetEnumerator();

PS: The little piece of indirection in the explicit definition for IEnumerable works because inside the function the compiler knows that the actual type of the variable is a StringList, and that's how it resolves the function call. Nifty little fact for implementing some of the layers of abstraction some of the .NET core interfaces seem to have accumulated.

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.

To solve your requirement, here is the working solution -

First create your ViewModels in following way. PersonModel can have list of RoleModels.

public class PersonModel
{
    public List<RoleModel> Roles { get; set; }
    public string Name { get; set; }
}

public class RoleModel
{
    public string RoleName { get; set;}
    public string Description { get; set;}
}

Then have a index action which will be serving basic index view -

public ActionResult Index()
{
    return View();
}

Index view will be having following JQuery AJAX POST operation -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    $(function () {
        $('#click1').click(function (e) {

            var jsonObject = {
                "Name" : "Rami",
                "Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
            };

            $.ajax({
                url: "@Url.Action("AddUser")",
                type: "POST",
                data: JSON.stringify(jsonObject),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

<input type="button" value="click1" id="click1" />

Index action posts to AddUser action -

[HttpPost]
public ActionResult AddUser(PersonModel model)
{
    if (model != null)
    {
        return Json("Success");
    }
    else
    {
        return Json("An Error Has occoured");
    }
}

So now when the post happens you can get all the posted data in the model parameter of action.

Update:

For asp.net core, to get JSON data as your action parameter you should add the [FromBody] attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController] attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)

Array.prototype.indexOf.call(this.parentElement.children, this);

Or use let statement.

I assume you want to strip all extensions, i.e. /tmp/test/somefile.tar.gz to somefile.

Direct approach with regex:

var filename = filepath.match(/^.*?([^\\/.]*)[^\\/]*$/)[1];

Alternative approach with regex and array operation:

var filename = filepath.split(/[\\/]/g).pop().split('.')[0];

An other way of CASE:

SELECT *  
FROM MyTable
WHERE 1 = CASE WHEN @myParm = value1 AND MyColumn IS NULL     THEN 1 
               WHEN @myParm = value2 AND MyColumn IS NOT NULL THEN 1 
               WHEN @myParm = value3                          THEN 1 
          END

Here's the most simplest code for everyone

Note: Showing Pearson's Rho and not R^2.

library(ggplot2)
library(ggpubr)

df <- data.frame(x = c(1:100)
df$y <- 2 + 3 * df$x + rnorm(100, sd = 40)
p <- ggplot(data = df, aes(x = x, y = y)) +
        geom_smooth(method = "lm", se=FALSE, color="black", formula = y ~ x) +
        geom_point()+
        stat_cor(label.y = 35)+ #this means at 35th unit in the y axis, the r squared and p value will be shown
        stat_regline_equation(label.y = 30) #this means at 30th unit regresion line equation will be shown

p

Check out HTTP: Method Definitions: POST.

The action performed by the POST method might not result in a resource that can be identified by a URI. In this case, either 200 (OK) or 204 (No Content) is the appropriate response status, depending on whether or not the response includes an entity that describes the result.

If a resource has been created on the origin server, the response SHOULD be 201 (Created) and contain an entity which describes the status of the request and refers to the new resource, and a Location header (see section 14.30).

PostgreSQL has a guide on how to best populate a database initially, and they suggest using the COPY command for bulk loading rows. The guide has some other good tips on how to speed up the process, like removing indexes and foreign keys before loading the data (and adding them back afterwards).

Add the following dependencies

<dependency>
    <groupId>org.codehaus.jackson</groupId> 
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.7</version>
</dependency>

<dependency>
    <groupId>org.codehaus.jackson</groupId> 
    <artifactId>jackson-core-asl</artifactId>
    <version>1.9.7</version>
</dependency>

Modify request as follows

$.ajax({ 
    url:urlName,    
    type:"POST", 
    contentType: "application/json; charset=utf-8",
    data: jsonString, //Stringified Json Object
    async: false,    //Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation
    cache: false,    //This will force requested pages not to be cached by the browser          
    processData:false, //To avoid making query String instead of JSON
    success: function(resposeJsonObject){
        // Success Message Handler
    }
});

Controller side

@RequestMapping(value = urlPattern , method = RequestMethod.POST)
public @ResponseBody Person save(@RequestBody Person jsonString) {

   Person person=personService.savedata(jsonString);
   return person;
}

@RequestBody - Covert Json object to java
@ResponseBody- convert Java object to json

If you are using jruby instead of ruby you will have similar issues when installing the pg gem. Instead you need to install the adaptor:

gem 'activerecord-jdbcpostgresql-adapter'

The short answer

Use one of these two methods:

• Class.getResource(String)
• Class.getResourceAsStream(String)

For example:

InputStream inputStream = YourClass.class.getResourceAsStream("image.jpg");

--

The long answer

Typically, one would not want to load files using absolute paths. For example, don’t do this if you can help it:

File file = new File("C:\\Users\\Joe\\image.jpg");

This technique is not recommended for at least two reasons. First, it creates a dependency on a particular operating system, which prevents the application from easily moving to another operating system. One of Java’s main benefits is the ability to run the same bytecode on many different platforms. Using an absolute path like this makes the code much less portable.

Second, depending on the relative location of the file, this technique might create an external dependency and limit the application’s mobility. If the file exists outside the application’s current directory, this creates an external dependency and one would have to be aware of the dependency in order to move the application to another machine (error prone).

Instead, use the getResource() methods in the Class class. This makes the application much more portable. It can be moved to different platforms, machines, or directories and still function correctly.

Given that this is a schedule of jobs, I suspect that at some point you are going to sort them into a proposed order of execution.

If that's the case, then a topological sort implementation may in any case detect cycles. UNIX tsort certainly does. I think it is likely that it is therefore more efficient to detect cycles at the same time as tsorting, rather than in a separate step.

So the question might become, "how do I most efficiently tsort", rather than "how do I most efficiently detect loops". To which the answer is probably "use a library", but failing that the following Wikipedia article:

http://en.wikipedia.org/wiki/Topological_sorting

has the pseudo-code for one algorithm, and a brief description of another from Tarjan. Both have O(|V| + |E|) time complexity.

While using the date formats, you may want to keep in mind to always use MM for months and mm for minutes. That should resolve your problem.

Here is the simplest way:

    SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss a", Locale.US);

    String time = df.format(new Date());

and If you are looking for patterns, check this https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

I have been struggling to find a proper way to create a timeline, which I could finally do with this modification. Usually while creating a timeline the problem was that I could not add a text to explain each date clearly with a longer text. I modified and further utilized @Zoe Gagnon's latex script.

Longer texts are not allowed, unfortunately. It will look like this:

>>> s1="abc def ghi"
>>> s2="def ghi abc"
>>> s1 == s2  # For string comparison 
False
>>> sorted(list(s1)) == sorted(list(s2)) # For comparing if they have same characters. 
True
>>> sorted(list(s1))
[' ', ' ', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i']
>>> sorted(list(s2))

why not use flexbox ? so wrap them into another div like that

.flexContainer { _x000D_
   _x000D_
  margin: 2px 10px;_x000D_
  display: flex;_x000D_
} _x000D_
_x000D_
.left {_x000D_
  flex-basis : 30%;_x000D_
}_x000D_
_x000D_
.right {_x000D_
  flex-basis : 30%;_x000D_
}

<form id="new_production" class="simple_form new_production" novalidate="novalidate" method="post" action="/projects/1/productions" accept-charset="UTF-8">_x000D_
    <div style="margin:0;padding:0;display:inline">_x000D_

    </div>_x000D_
    <div class="input string required"> </div>_x000D_

feel free to play with flex-basis percentage to get more customized space.

You can use Application class(public class in android.application package),that is:

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's tag, which will cause that class to be instantiated for you when the process for your application/package is created.

To use this class do:

public class App extends Application {

    private static Context mContext;

    public static Context getContext() {
        return mContext;
    }

    public static void setContext(Context mContext) {
        this.mContext = mContext;
    }

    ...

}

In your manifest:

<application
        android:icon="..."
        android:label="..."
        android:name="com.example.yourmainpackagename.App" >
                       class that extends Application ^^^

In Activity B:

public class B extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.sampleactivitylayout);

        App.setContext(this);
                  ...
        }
...
}

In class A:

Context c = App.getContext();

Note:

There is normally no need to subclass Application. In most situation, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), the function to retrieve it can be given a Context which internally uses Context.getApplicationContext() when first constructing the singleton.

You can invoke methods of a class instance using reflection, doing a dynamic method invocation:

Suppose that you have a method called hello in a the actual instance (this):

string methodName = "hello";

//Get the method information using the method info class
 MethodInfo mi = this.GetType().GetMethod(methodName);

//Invoke the method
// (null- no parameter for the method call
// or you can pass the array of parameters...)
mi.Invoke(this, null);

Nicolas solution is best. If you want in regex,

try this,

this will validate for, 01/01/1900 through 12/31/2099 Matches invalid dates such as February 31st Accepts dashes, spaces, forward slashes and dots as date separators

(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)[0-9]{2}

The column I'm sorting with has any combination of alpha and numeric, so I used the suggestions in this post as a starting point and came up with this.

DECLARE @tmp TABLE (ID VARCHAR(50));
INSERT INTO @tmp VALUES ('XYZ300');
INSERT INTO @tmp VALUES ('XYZ1002');
INSERT INTO @tmp VALUES ('106');
INSERT INTO @tmp VALUES ('206');
INSERT INTO @tmp VALUES ('1002');
INSERT INTO @tmp VALUES ('J206');
INSERT INTO @tmp VALUES ('J1002');

SELECT ID, (CASE WHEN ISNUMERIC(ID) = 1 THEN 0 ELSE 1 END) IsNum
FROM @tmp
ORDER BY IsNum, LEN(ID), ID;

Results

ID
------------------------
106
206
1002
J206
J1002
XYZ300
XYZ1002

Hope this helps

For completeness sake, and for those that do not wish to use the Interface Builder, here's a way of creating the same table as in Suragch's answer entirely programatically - albeit with a different size and position.

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource  {

    var tableView: UITableView = UITableView()
    let animals = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
    let cellReuseIdentifier = "cell"

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.frame = CGRectMake(0, 50, 320, 200)
        tableView.delegate = self
        tableView.dataSource = self
        tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)

        self.view.addSubview(tableView)
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return animals.count
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellReuseIdentifier) as UITableViewCell!

        cell.textLabel?.text = animals[indexPath.row]

        return cell
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }

}

Make sure you have remembered to import UIKit.

For Windows users: curly braces have special meaning in PowerShell. You can either surround with single quotes or escape with backtick. For example:

git checkout 'stash@{0}' YourFile

Without it, you may receive an error:

Unknown switch 'e'

Given that a WHERE clause did not work, maybe this will:

CREATE TRIGGER 
    [dbo].[SystemParameterInsertUpdate]
ON 
    [dbo].[SystemParameter]
FOR INSERT, UPDATE 
AS
  BEGIN
    SET NOCOUNT ON

      If (SELECT Attribute FROM INSERTED) LIKE 'NoHist_%'
      Begin
          Return
      End

      INSERT INTO SystemParameterHistory 
      (
        Attribute,
        ParameterValue,
        ParameterDescription,
        ChangeDate
      )
    SELECT
      Attribute,
      ParameterValue,
      ParameterDescription,
      ChangeDate
    FROM Inserted AS I
END

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

I have solved it this way.

Go to your project file let's say project/name/bin and delete everything within the bin folder. (this will then give you another error which you can solve this way)

then in your visual studio right click project's References folder, to open NuGet Package Manager.

Go to browse and install "DotNetCompilerPlatform".

I don't like the solution of settings widths on .btn because it assumes there'll always be the same number of items in the .btn-group. This is a faulty assumption and leads to bloated, presentation-specific CSS.

A better solution is to change how .btn-group with .btn-block and child .btn(s) are display. I believe this is what you're looking for:

.btn-group.btn-block {
    display: table;
}
.btn-group.btn-block > .btn {
    display: table-cell;
}

Here's a fiddle: http://jsfiddle.net/DEwX8/123/

If you'd prefer to have equal-width buttons (within reason) and can support only browsers that support flexbox, try this instead:

.btn-group.btn-block {
    display: flex;
}
.btn-group.btn-block > .btn {
    flex: 1;
}

Here's a fiddle: http://jsfiddle.net/DEwX8/124/

So what is this "require?"

require() is not part of the standard JavaScript API. But in Node.js, it's a built-in function with a special purpose: to load modules.

Modules are a way to split an application into separate files instead of having all of your application in one file. This concept is also present in other languages with minor differences in syntax and behavior, like C's include, Python's import, and so on.

One big difference between Node.js modules and browser JavaScript is how one script's code is accessed from another script's code.

• In browser JavaScript, scripts are added via the <script> element. When they execute, they all have direct access to the global scope, a "shared space" among all scripts. Any script can freely define/modify/remove/call anything on the global scope.

• In Node.js, each module has its own scope. A module cannot directly access things defined in another module unless it chooses to expose them. To expose things from a module, they must be assigned to exports or module.exports. For a module to access another module's exports or module.exports, it must use require().

In your code, var pg = require('pg'); loads the pg module, a PostgreSQL client for Node.js. This allows your code to access functionality of the PostgreSQL client's APIs via the pg variable.

Why does it work in node but not in a webpage?

require(), module.exports and exports are APIs of a module system that is specific to Node.js. Browsers do not implement this module system.

Also, before I got it to work in node, I had to do npm install pg. What's that about?

NPM is a package repository service that hosts published JavaScript modules. npm install is a command that lets you download packages from their repository.

Where did it put it, and how does Javascript find it?

The npm cli puts all the downloaded modules in a node_modules directory where you ran npm install. Node.js has very detailed documentation on how modules find other modules which includes finding a node_modules directory.

Select distinct PROJ_UID,PROJ_NAME,RES_UID from E2E_ProjectWiseTimesheetActuals

My project should use the 'latest' for the submodule. On Mac OSX 10.11, git version 2.7.1, I did not need to go 'into' my submodule folder in order to collect its commits. I merely did a regular

git pull --rebase 

at the top level, and it correctly updated my submodule.

On any linux system with the NVIDIA driver installed and loaded into the kernel, you can execute:

cat /proc/driver/nvidia/version

to get the version of the currently loaded NVIDIA kernel module, for example:

$ cat /proc/driver/nvidia/version 
NVRM version: NVIDIA UNIX x86_64 Kernel Module  304.54  Sat Sep 29 00:05:49 PDT 2012
GCC version:  gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) 

Single quotes are used to indicate the beginning and end of a string in SQL. Double quotes generally aren't used in SQL, but that can vary from database to database.

Stick to using single quotes.

That's the primary use anyway. You can use single quotes for a column alias — where you want the column name you reference in your application code to be something other than what the column is actually called in the database. For example: PRODUCT.id would be more readable as product_id, so you use either of the following:

• SELECT PRODUCT.id AS product_id
• SELECT PRODUCT.id 'product_id'

Either works in Oracle, SQL Server, MySQL… but I know some have said that the TOAD IDE seems to give some grief when using the single quotes approach.

You do have to use single quotes when the column alias includes a space character, e.g., product id, but it's not recommended practice for a column alias to be more than one word.

There are different ways to return status code, 1 : RestController class should extends BaseRest class, in BaseRest class we can handle exception and return expected error codes. for example :

@RestController
@RequestMapping
class RestController extends BaseRest{

}

@ControllerAdvice
public class BaseRest {
@ExceptionHandler({Exception.class,...})
    @ResponseStatus(value=HttpStatus.INTERNAL_SERVER_ERROR)
    public ErrorModel genericError(HttpServletRequest request, 
            HttpServletResponse response, Exception exception) {
        
        ErrorModel error = new ErrorModel();
        resource.addError("error code", exception.getLocalizedMessage());
        return error;
    }

Easier and more succinct with || ...:

$(document).ready(function(){


  var str = ((document.getElementById("cal_preview")||{}).value)||"";
  var str1 = ((document.getElementById("year")||{}).value)||"";
  var str2 = ((document.getElementById("holiday")||{}).value)||"";
  var str3 = ((document.getElementById("cal_option")||{}).value)||"";


    if (str=="" && str1=="" && str2=="" && str3=="" )
      {
        document.getElementById("calendar_preview").innerHTML="";
          return;
        } 
      if (window.XMLHttpRequest)
      {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
      }
      else
      {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }

      xmlhttp.onreadystatechange=function()
      {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
          {
            document.getElementById("calendar_preview").innerHTML=xmlhttp.responseText;
          }
      }

    var url = calendar_preview_vars.plugin_url + "?id=" + str +"&"+"y="+str1+"&"+"h="+str2+"&"+"opt="+str3;
    xmlhttp.open("GET",url,true);
    xmlhttp.send();

Actually, there are many ways to do it. Some are harder from others, but it is up to you which one suits you best. I will try to showcase them all.

#1 Programatically in your app

Seems to be the easiest, but you will need to recompile your app to change those settings. Personally, I don't like it but it works fine.

Example:

import org.apache.log4j.{Level, Logger}

val rootLogger = Logger.getRootLogger()
rootLogger.setLevel(Level.ERROR)

Logger.getLogger("org.apache.spark").setLevel(Level.WARN)
Logger.getLogger("org.spark-project").setLevel(Level.WARN)

You can achieve much more just using log4j API.

#2 Pass log4j.properties during spark-submit

This one is very tricky, but not impossible. And my favorite.

Log4J during app startup is always looking for and loading log4j.properties file from classpath.

However, when using spark-submit Spark Cluster's classpath has precedence over app's classpath! This is why putting this file in your fat-jar will not override the cluster's settings!

Add -Dlog4j.configuration=<location of configuration file> to spark.driver.extraJavaOptions (for the driver) or
spark.executor.extraJavaOptions (for executors).

Note that if using a file, the file: protocol should be explicitly provided, and the file needs to exist locally on all the nodes.

To satisfy the last condition, you can either upload the file to the location available for the nodes (like hdfs) or access it locally with driver if using deploy-mode client. Otherwise:

upload a custom log4j.properties using spark-submit, by adding it to the --files list of files to be uploaded with the application.

Source: Spark docs, Debugging

Steps:

Example log4j.properties:

# Blacklist all to warn level
log4j.rootCategory=WARN, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.err
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n

# Whitelist our app to info :)
log4j.logger.com.github.atais=INFO

Executing spark-submit, for cluster mode:

spark-submit \
    --master yarn \
    --deploy-mode cluster \
    --conf "spark.driver.extraJavaOptions=-Dlog4j.configuration=file:log4j.properties" \
    --conf "spark.executor.extraJavaOptions=-Dlog4j.configuration=file:log4j.properties" \
    --files "/absolute/path/to/your/log4j.properties" \
    --class com.github.atais.Main \
    "SparkApp.jar"

Note that you must use --driver-java-options if using client mode. Spark docs, Runtime env

Executing spark-submit, for client mode:

spark-submit \
    --master yarn \
    --deploy-mode client \
    --driver-java-options "-Dlog4j.configuration=file:/absolute/path/to/your/log4j.properties \
    --conf "spark.executor.extraJavaOptions=-Dlog4j.configuration=file:log4j.properties" \
    --files "/absolute/path/to/your/log4j.properties" \
    --class com.github.atais.Main \
    "SparkApp.jar"

Notes:

1. Files uploaded to spark-cluster with --files will be available at root dir, so there is no need to add any path in file:log4j.properties.
2. Files listed in --files must be provided with absolute path!
3. file: prefix in configuration URI is mandatory.

#3 Edit cluster's conf/log4j.properties

This changes global logging configuration file.

update the $SPARK_CONF_DIR/log4j.properties file and it will be automatically uploaded along with the other configurations.

Source: Spark docs, Debugging

To find your SPARK_CONF_DIR you can use spark-shell:

atais@cluster:~$ spark-shell 
Welcome to
      ____              __
     / __/__  ___ _____/ /__
    _\ \/ _ \/ _ `/ __/  '_/
   /___/ .__/\_,_/_/ /_/\_\   version 2.1.1
      /_/   

scala> System.getenv("SPARK_CONF_DIR")
res0: String = /var/lib/spark/latest/conf

Now just edit /var/lib/spark/latest/conf/log4j.properties (with example from method #2) and all your apps will share this configuration.

#4 Override configuration directory

If you like the solution #3, but want to customize it per application, you can actually copy conf folder, edit it contents and specify as the root configuration during spark-submit.

To specify a different configuration directory other than the default “SPARK_HOME/conf”, you can set SPARK_CONF_DIR. Spark will use the configuration files (spark-defaults.conf, spark-env.sh, log4j.properties, etc) from this directory.

Source: Spark docs, Configuration

Steps:

1. Copy cluster's conf folder (more info, method #3)
2. Edit log4j.properties in that folder (example in method #2)

3. Set SPARK_CONF_DIR to this folder, before executing spark-submit,
   example:

   export SPARK_CONF_DIR=/absolute/path/to/custom/conf
   
   spark-submit \
       --master yarn \
       --deploy-mode cluster \
       --class com.github.atais.Main \
       "SparkApp.jar"
   

Conclusion

I am not sure if there is any other method, but I hope this covers the topic from A to Z. If not, feel free to ping me in the comments!

Enjoy your way!

First you create the EditText in the xml file and assign an id, eg con_pag_etPesquisa. After that, we will create two lists, where one is the list view and the other to receive the same content but will remain as a backup. Before moving objects to lists first initializes Them the below:

//Declaring

public EditText etPesquisa;

public ContasPagarAdapter adapterNormal;

public List<ContasPagar> lstBkp;

public List<ContasPagar> lstCp;

//Within the onCreate method, type the following:

etPesquisa = (EditText) findViewById(R.id.con_pag_etPesquisa);

etPesquisa.addTextChangedListener(new TextWatcher(){

    @Override
    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
        filter(String.valueOf(cs));
    }
    @Override
    public void beforeTextChanged(CharSequence cs, int arg1, int arg2, int arg3){

    // TODO Auto-generated method stub
    }
    @Override
    public void afterTextChanged(Editable e){

    }

});

//Before moving objects to lists first initializes them as below:

lstCp = new ArrayList<ContasPagar>();

lstBkp = new ArrayList<ContasPagar>();


//When you add objects to the main list, repeat the procedure also for bkp list, as follows:

lstCp.add(cp);

lstBkp.add(cp);


//Now initializes the adapter and let the listener, as follows:

adapterNormal = new ContasPagarAdapter(ContasPagarActivity.this, lstCp);

lvContasPagar.setAdapter(adapterNormal);
                    lvContasPagar.setOnItemClickListener(verificaClickItemContasPagar(lstCp));


//Now create the methods inside actito filter the text entered by the user, as follows:

public void filter(String charText){

    charText = charText.toLowerCase();

    lstCp.clear();

    if (charText.length() == 0){

        lstCp.addAll(lstBkp);

        appendAddItem(lstBkp);

    } 

    else {

        for (int i = 0; i < lstBkp.size(); i++){

            if((lstBkp.get(i).getNome_lancamento() + " - " + String.valueOf(lstBkp.get(i).getCodigo())).toLowerCase().contains(charText)){

                lstCp.add(lstBkp.get(i));

            }

        }

        appendAddItem(lstCp);
    }
}

private void appendAddItem(final List<ContasPagar> novaLista){
    runOnUiThread(new Runnable(){

        @Override
            public void run(){
                adapterNormal.notifyDataSetChanged();               
            }
        });
    }

if you do ctrl-z and then type exit it will close background applications.

Ctrl+Q is another good way to kill the application.

For MVC3 you don't have to add any dummy files to set a certain browser. All you have to do is:

• "Show all files" for the project
• go to bin folder
• right click the only .xml file to find the "Browse With..." option

Probably because it just didn't make much sense for list semantics. However, you can easily create your own by subclassing.

class safelist(list):
    def get(self, index, default=None):
        try:
            return self.__getitem__(index)
        except IndexError:
            return default

def _test():
    l = safelist(range(10))
    print l.get(20, "oops")

if __name__ == "__main__":
    _test()

Looks like this is unimplemented, as of the time of this writing:

https://github.com/sass/sass/issues/193

For libsass (C/C++ implementation), import works for *.css the same way as for *.scss files - just omit the extension:

@import "path/to/file";

This will import path/to/file.css.

See this answer for further details.

See this answer for Ruby implementation (sass gem)

Complex types are in the C language since C99 standard (-std=c99 option of GCC). Some compilers may implement complex types even in more earlier modes, but this is non-standard and non-portable extension (e.g. IBM XL, GCC, may be intel,... ).

You can start from http://en.wikipedia.org/wiki/Complex.h - it gives a description of functions from complex.h

This manual http://pubs.opengroup.org/onlinepubs/009604499/basedefs/complex.h.html also gives some info about macros.

To declare a complex variable, use

  double _Complex  a;        // use c* functions without suffix

or

  float _Complex   b;        // use c*f functions - with f suffix
  long double _Complex c;    // use c*l functions - with l suffix

To give a value into complex, use _Complex_I macro from complex.h:

  float _Complex d = 2.0f + 2.0f*_Complex_I;

(actually there can be some problems here with (0,-0i) numbers and NaNs in single half of complex)

Module is cabs(a)/cabsl(c)/cabsf(b); Real part is creal(a), Imaginary is cimag(a). carg(a) is for complex argument.

To directly access (read/write) real an imag part you may use this unportable GCC-extension:

 __real__ a = 1.4;
 __imag__ a = 2.0;
 float b = __real__ a;

The subquery option has already been answered, but note that in many cases a LEFT JOIN can be a faster way to do this:

SELECT table1.*
FROM table1 LEFT JOIN table2 ON table2.principal=table1.principal
WHERE table2.principal IS NULL

If you want to check multiple tables to make sure it's not present in any of the tables (like in SRKR's comment), you can use this:

SELECT table1.*
FROM table1
LEFT JOIN table2 ON table2.name=table1.name
LEFT JOIN table3 ON table3.name=table1.name
WHERE table2.name IS NULL AND table3.name IS NULL

XDocument xdoc = XDocument.Load("data.xml");
var lv1s = xdoc.Root.Descendants("level1"); 
var lvs = lv1s.SelectMany(l=>
     new string[]{ l.Attribute("name").Value }
     .Union(
         l.Descendants("level2")
         .Select(l2=>"   " + l2.Attribute("name").Value)
      )
    );
foreach (var lv in lvs)
{
   result.AppendLine(lv);
}

Ps. You have to use .Root on any of these versions.

I think it's asking you to do this:

SELECT ID
FROM (SELECT ID,
             msisdn 
      FROM (SELECT * FROM TT2) as myalias
     ) as anotheralias;

But why would you write this query in the first place?

There isn't an expiration date for the community edition.

The usage section from the from the Visual Studio website clearly states:

For individuals

Any individual developer can use Visual Studio Community to create their own free or paid apps.

For organizations

An unlimited number of users within an organization can use Visual Studio Community for the following scenarios: in a classroom learning environment, for academic research, or for contributing to open source projects.

For all other usage scenarios: In non-enterprise organizations, up to five users can use Visual Studio Community. In enterprise organizations (meaning those with >250 PCs or >$1 Million US Dollars in annual revenue), no use is permitted beyond the open source, academic research, and classroom learning environment scenarios described above.

Since I've updated to Android Oreo, I had to use this script to fix 'permission denied' issue.

This script on Mac OS X will copy your db file to Desktop. Just change it to match your ADB_PATH, DESTINATION_PATH and PACKAGE NAME.

#!/bin/sh
ADB_PATH="/Users/xyz/Library/Android/sdk/platform-tools"
PACKAGE_NAME="com.example.android"
DB_NAME="default.realm"
DESTINATION_PATH="/Users/xyz/Desktop/${DB_NAME}"
NOT_PRESENT="List of devices attached"
ADB_FOUND=`${ADB_PATH}/adb devices | tail -2 | head -1 | cut -f 1 | sed 's/ *$//g'`
if [[ ${ADB_FOUND} == ${NOT_PRESENT} ]]; then
    echo "Make sure a device is connected"
else
     ${ADB_PATH}/adb exec-out run-as ${PACKAGE_NAME} cat files/${DB_NAME} > ${DESTINATION_PATH}
fi

This is actually the conventional use of the break statement. If the break statement wasn't nested in an if block the for loop could only ever execute one time.

MSDN lists this as their example for the break statement.

The (+) operator indicates an outer join. This means that Oracle will still return records from the other side of the join even when there is no match. For example if a and b are emp and dept and you can have employees unassigned to a department then the following statement will return details of all employees whether or not they've been assigned to a department.

select * from emp, dept where emp.dept_id=dept.dept_id(+)

So in short, removing the (+) may make a significance difference but you might not notice for a while depending on your data!

Something like that:

def runProcess(exe):    
    p = subprocess.Popen(exe, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    while(True):
        # returns None while subprocess is running
        retcode = p.poll() 
        line = p.stdout.readline()
        yield line
        if retcode is not None:
            break

Note, that I'm redirecting stderr to stdout, it might not be exactly what you want, but I want error messages also.

This function yields line by line as they come (normally you'd have to wait for subprocess to finish to get the output as a whole).

For your case the usage would be:

for line in runProcess('mysqladmin create test -uroot -pmysqladmin12'.split()):
    print line,

I was in need of copying the data from one workbook to another using VBA. The requirement was as mentioned below 1. On pressing an Active X button open the dialogue to select the file from which the data needs to be copied. 2. On clicking OK the value should get copied from a cell / range to currently working workbook.

I did not want to use the open function because it opens the workbook which will be annoying

Below is the code that I wrote in the VBA. Any improvement or new alternative is welcome.

Add text-align:center;display:block; to the css class. Better than setting a style on the controls themselves. If you want to change it you do so in one place.

There's a codec in uuid-creator that can do it more efficiently: Base16Codec. Example:

// Returns a base-16 string
// It is much faster than doing `uuid.toString().replaceAll("-", "")`.
UuidCodec<String> codec = new Base16Codec();
String string = codec.encode(UUID.randomUUID());

If you write on Kotlin, you can use:

val firstProcess = ProcessBuilder("echo","hello world").start()
val firstError = firstProcess.errorStream.readBytes().decodeToString()
val firstResult = firstProcess.inputStream.readBytes().decodeToString()

The NativeHeap can be increasded by -XX:MaxDirectMemorySize=256M (default is 128)

I've never used it. Maybe you'll find it useful.

I had the same problem, I fixed it by removing PATHEXT from user variable. It must only exist in System variable with .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

Also remove the variable from user to system and only include that path on user variable

That's Media Queries. It allows you to apply part of CSS rules only to the specific devices on specific configuration.

I'm not sure if I understood correctly, but is this what you mean?

out.write("this is line 1");
out.newLine();
out.write("this is line 2");
out.newLine();
...

In order to kill use: killall -9 /usr/bin/node

To reload use: killall -12 /usr/bin/node

This is my take on it:

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

    private int code;

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

    public int getCode() {
        return code;
    }

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

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

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

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

where pref and editor are SharedPreferences and a SharedPreferences.Editor

There's no need to manually set the colors. Instead, specify a grayscale colormap...

import numpy as np
import matplotlib.pyplot as plt

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()

plt.show()

Or, if you'd prefer a wider range of colormaps, you can also specify the cmap kwarg to scatter. To use the reversed version of any of these, just specify the "_r" version of any of them. E.g. gray_r instead of gray. There are several different grayscale colormaps pre-made (e.g. gray, gist_yarg, binary, etc).

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()

To stop all running emulators we use this command:

adb devices | grep emulator | cut -f1 | while read line; do adb -s $line emu kill; done

This will give you the option to:

1. Overwrite or Preserve a tab that has the same name.
2. Place the sheet at End of all tabs or Next to the current tab.
3. Select your New sheet or the Active one.

Call CreateWorksheet("New", False, False, False)


Sub CreateWorksheet(sheetName, preserveOldSheet, isLastSheet, selectActiveSheet)
  activeSheetNumber = Sheets(ActiveSheet.Name).Index

  If (Evaluate("ISREF('" & sheetName & "'!A1)")) Then 'Does sheet exist?
    If (preserveOldSheet) Then
      MsgBox ("Can not create sheet " + sheetName + ". This sheet exist.")
      Exit Sub
    End If
      Application.DisplayAlerts = False
      Worksheets(sheetName).Delete
    End If

    If (isLastSheet) Then
      Sheets.Add(After:=Sheets(Sheets.Count)).Name = sheetName 'Place sheet at the end.
    Else 'Place sheet after the active sheet.
      Sheets.Add(After:=Sheets(activeSheetNumber)).Name = sheetName
    End If

    If (selectActiveSheet) Then
      Sheets(activeSheetNumber).Activate
    End If

End Sub

Stored as strings:

public class ReadTemps {

    public static void main(String[] args) throws IOException {
    // TODO code application logic here

    // // read KeyWestTemp.txt

    // create token1
    String token1 = "";

    // for-each loop for calculating heat index of May - October

    // create Scanner inFile1
    Scanner inFile1 = new Scanner(new File("KeyWestTemp.txt")).useDelimiter(",\\s*");

    // Original answer used LinkedList, but probably preferable to use ArrayList in most cases
    // List<String> temps = new LinkedList<String>();
    List<String> temps = new ArrayList<String>();

    // while loop
    while (inFile1.hasNext()) {
      // find next line
      token1 = inFile1.next();
      temps.add(token1);
    }
    inFile1.close();

    String[] tempsArray = temps.toArray(new String[0]);

    for (String s : tempsArray) {
      System.out.println(s);
    }
  }
}

For floats:

import java.io.File;
import java.io.IOException;
import java.util.LinkedList;
import java.util.List;
import java.util.Scanner;

public class ReadTemps {

  public static void main(String[] args) throws IOException {
    // TODO code application logic here

    // // read KeyWestTemp.txt

    // create token1

    // for-each loop for calculating heat index of May - October

    // create Scanner inFile1
    Scanner inFile1 = new Scanner(new File("KeyWestTemp.txt")).useDelimiter(",\\s*");


    // Original answer used LinkedList, but probably preferable to use ArrayList in most cases
    // List<Float> temps = new LinkedList<Float>();
    List<Float> temps = new ArrayList<Float>();

    // while loop
    while (inFile1.hasNext()) {
      // find next line
      float token1 = inFile1.nextFloat();
      temps.add(token1);
    }
    inFile1.close();

    Float[] tempsArray = temps.toArray(new Float[0]);

    for (Float s : tempsArray) {
      System.out.println(s);
    }
  }
}

You can't replace a letter in a string. Convert the string to a list, replace the letter, and convert it back to a string.

>>> s = list("Hello world")
>>> s
['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']
>>> s[int(len(s) / 2)] = '-'
>>> s
['H', 'e', 'l', 'l', 'o', '-', 'W', 'o', 'r', 'l', 'd']
>>> "".join(s)
'Hello-World'

The itertools module contains a filter function for iterators. The first element of the filtered iterator can be obtained by calling next() on it:

from itertools import ifilter

print ifilter((lambda i: i > 3), range(10)).next()

Angular Material 10 now includes a new date range picker.

To use the new date range picker, you can use the mat-date-range-input and mat-date-range-picker components.

Example

HTML

<mat-form-field>
  <mat-label>Enter a date range</mat-label>
  <mat-date-range-input [rangePicker]="picker">
    <input matStartDate matInput placeholder="Start date">
    <input matEndDate matInput placeholder="End date">
  </mat-date-range-input>
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-date-range-picker #picker></mat-date-range-picker>
</mat-form-field>

You can read and learn more about this in their official documentation.

Unfortunately, they still haven't build a timepicker on this release.

You will need these imports...

import javax.servlet.*;
import javax.servlet.http.*;

And, if you're using Maven, you'll also need this in the dependencies block of the pom.xml file in your project's base directory.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

Then the above-listed fix by Jason will work:

@ResponseBody
    public ResponseEntity<Boolean> saveData(HttpServletRequest request,
        HttpServletResponse response, Model model){
        String jsonString = request.getParameter("json");
    }

Building on a previous answer by @user1172173 that addressed SQL Injection vulnerabilities, see below:

CREATE PROCEDURE [dbo].[spQ_SomeColumnByCustomerId](
@CustomerId int,
@SchemaName varchar(20),
@TableName nvarchar(200)) AS
SET Nocount ON
DECLARE @SQLQuery AS NVARCHAR(500)
DECLARE @ParameterDefinition AS NVARCHAR(100)
DECLARE @Table_ObjectId int;
DECLARE @Schema_ObjectId int;
DECLARE @Schema_Table_SecuredFromSqlInjection NVARCHAR(125)

SET @Table_ObjectId = OBJECT_ID(@TableName)
SET @Schema_ObjectId = SCHEMA_ID(@SchemaName)
SET @Schema_Table_SecuredFromSqlInjection = SCHEMA_NAME(@Schema_ObjectId) + '.' + OBJECT_NAME(@Table_ObjectId)

SET @SQLQuery = N'SELECT TOP 1 ' + @Schema_Table_SecuredFromSqlInjection + '.SomeColumn 
FROM dbo.Customer 
INNER JOIN ' + @Schema_Table_SecuredFromSqlInjection + ' 
ON dbo.Customer.Customerid = ' + @Schema_Table_SecuredFromSqlInjection + '.CustomerId 
WHERE dbo.Customer.CustomerID = @CustomerIdParam 
ORDER BY ' + @Schema_Table_SecuredFromSqlInjection + '.SomeColumn DESC' 
SET @ParameterDefinition =  N'@CustomerIdParam INT'

EXECUTE sp_executesql @SQLQuery, @ParameterDefinition, @CustomerIdParam = @CustomerId; RETURN

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

This is my solution for something similar to this problem:

System.Windows.Forms.WebBrowser www;

void VerificarWebSites()
{
    www = new System.Windows.Forms.WebBrowser();
    www.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(www_DocumentCompleted_login);
    www.Navigate(new Uri("http://www.meusite.com.br"));
}

void www_DocumentCompleted_login(object sender, WebBrowserDocumentCompletedEventArgs e)
{            
    www.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(www_DocumentCompleted_login);
    www.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(www_DocumentCompleted_logado);

    www.Document.Forms[0].All["tbx_login"].SetAttribute("value", "Gostoso");
    www.Document.Forms[0].All["tbx_senha"].SetAttribute("value", "abcdef");
    www.Document.GetElementById("btn_login").Focus();
    www.Document.GetElementById("btn_login").InvokeMember("click");
}

void www_DocumentCompleted_logado(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    System.IO.StreamWriter sw = new StreamWriter("c:\\saida_teste.txt");
    sw.Write(www.DocumentText);
    sw.Close();
    MessageBox.Show(e.Url.AbsolutePath);
}

Working with msys2 I have obtained the same error trying to execute release version of my project in a debug environment. The solution for my problem is obvious: use executable with debug symbols.

git rm --cached is used to remove a file from the index. In the case where the file is already in the repo, git rm --cached will remove the file from the index, leaving it in the working directory and a commit will now remove it from the repo as well. Basically, after the commit, you would have unversioned the file and kept a local copy.

git reset HEAD file ( which by default is using the --mixed flag) is different in that in the case where the file is already in the repo, it replaces the index version of the file with the one from repo (HEAD), effectively unstaging the modifications to it.

In the case of unversioned file, it is going to unstage the entire file as the file was not there in the HEAD. In this aspect git reset HEAD file and git rm --cached are same, but they are not same ( as explained in the case of files already in the repo)

To the question of Why are there 2 ways to unstage a file in git? - there is never really only one way to do anything in git. that is the beauty of it :)

you can make a shell script with those commands, and then chmod +x <scriptname.sh>, and then just run it by

./scriptname.sh

Its very simple to write a bash script

Mockup sh file:

#!/bin/sh
sudo command1
sudo command2 
.
.
.
sudo commandn

You can use lsof (list of open files) in most cases to find open log files without knowing the configuration.

Example:

Find the PID of httpd (the same concept applies for nginx and other programs):

$ ps aux | grep httpd
...
root     17970  0.0  0.3 495964 64388 ?        Ssl  Oct29   3:45 /usr/sbin/httpd
...

Then search for open log files using lsof with the PID:

$ lsof -p 17970 | grep log
httpd   17970 root    2w   REG             253,15     2278      6723 /var/log/httpd/error_log
httpd   17970 root   12w   REG             253,15        0      1387 /var/log/httpd/access_log

If lsof prints nothing, even though you expected the log files to be found, issue the same command using sudo.

You can read a little more here.

In .net2.0 you can use the variable Application.UserAppDataPath

If all else fails you can also use

"My text needs a line break here" + System.Environment.NewLine + " This should be a new line"

If you use the static method and load the properties file from the classpath folder so you can use the below code :

//load a properties file from class path, inside static method
Properties prop = new Properties();
prop.load(Classname.class.getClassLoader().getResourceAsStream("foo.properties"));

for those who need to print the call stack while using pdb, just do

(Pdb) where

Since you are explicitly also asking to handle columns that haven't yet been filled out, and I assume also don't want to mess with them if they have a word instead of a number, you might consider this:

=If(IsNumber(K23), If(K23 > 0, ........., 0), 0)

This just says... If K23 is a number; And if that number is greater than zero; Then do something ......... Otherwise, return zero.

In ........., you might put your division equation there, such as A1/K23, and you can rest assured that K23 is a number which is greater than zero.

you can simply do like that in the html part:

<span>Heading Text</span>

and in the css you can make it as an h1 block using display:

span{
display:block;
font-size:20px;
}

you will get it as a h1 without bold ,
if you want it bold just add this to the css:

font-weight:bold;

You may obtain the stream key via the API: https://github.com/justintv/twitch-api

The correct syntax for adding column into table is:

ALTER TABLE table_name
  ADD column_name column-definition;

In your case it will be:

ALTER TABLE Employees
  ADD EmployeeID int NOT NULL IDENTITY (1, 1)

To add multiple columns use brackets:

ALTER TABLE table_name
  ADD (column_1 column-definition,
       column_2 column-definition,
       ...
       column_n column_definition);

COLUMN keyword in SQL SERVER is used only for altering:

ALTER TABLE table_name
  ALTER COLUMN column_name column_type;

Check this plugin WP Media Folder at Joomunited, you can:

• Create visual folders and move file inside
• Restrict file visualisation
• Create galleries from folders
• ...

Since the last months they add a lot of must use features.

This is a paid plugin but it worth the money, I install it now by default on all my customers websites.

You could use a Regexp.

var result = /^(\d{2})-(\d{2})-(\d{4})$/.exec($("#datepicker").val());
if (result) {
    from = new Date(
        parseInt(result[3], 10), 
        parseInt(result[2], 10) - 1, 
        parseInt(result[1], 10)
    );
}

As this issue still exists, I thought I'd add something to RacZo's answer for development purposes. If you're not using the Eclipse plugin or for whatever reason you don't have the source, but just the .apk, you can increase the partition size from the command line using the same option when you launch the emulator:

emulator -avd <emulator name> -partition-size 1024

As far as I know, This option is not documented at developer.android.com, so I thought I'd post it here so people might find this solution.

As stated in the other answers, m_ prefix is used to indicate that a variable is a class member. This is different from Hungarian notation because it doesn't indicate the type of the variable but its context.

I use m_ in C++ but not in some other languages where 'this' or 'self' is compulsory. I don't like to see 'this->' used with C++ because it clutters the code.

Another answer says m_dsc is "bad practice" and 'description;' is "good practice" but this is a red herring because the problem there is the abbreviation.

Another answer says typing this pops up IntelliSense but any good IDE will have a hotkey to pop up IntelliSense for the current class members.

It is not necessary to encode a colon as %3B in the query, although doing so is not illegal.

URI         = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
query       = *( pchar / "/" / "?" )
pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded   = "%" HEXDIG HEXDIG
sub-delims    = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="

It also seems that only percent-encoded spaces are valid, as I doubt that space is an ALPHA or a DIGIT

look to the URI specification for more details.

Avoid of lot of fat fingering by starting with a Dictionary in the Model

namespace EzPL8.Models
{
    public class MyEggs
    {
        public Dictionary<int, string> Egg { get; set; }

        public MyEggs()
        {
            Egg = new Dictionary<int, string>()
            {
                { 0, "No Preference"},
                { 1, "I hate eggs"},
                { 2, "Over Easy"},
                { 3, "Sunny Side Up"},
                { 4, "Scrambled"},
                { 5, "Hard Boiled"},
                { 6, "Eggs Benedict"}
            };

    }


    }

In the View convert it to a list for display

@Html.DropDownListFor(m => m.Egg.Keys,
                         new SelectList(
                             Model.Egg, 
                             "Key", 
                             "Value"))

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

Another reason why you might get errors like "relation already exists" is if the DROP command did not execute correctly.

One reason this can happen is if there are other sessions connected to the database which you need to close first.

The problem is that you are trying to insert data into the database without using columns. Sql server gives you that error message.

error: insert into users values('1', '2','3') - this works fine as long you only have 3 columns

if you have 4 columns but only want to insert into 3 of them

correct: insert into users (firstName,lastName,city) values ('Tom', 'Jones', 'Miami')

hope this helps

See the Android documentation on controlling the emulator; it's Ctrl + F11 / Ctrl + F12.

On ThinkPad running Ubuntu, you may try CTRL + Left Arrow Key or Right Arrow Key

You can add the application folder to your path from a command prompt using:

setx PATH "%PATH%;c:\MinGW\bin"

Note that you will probably need to open a new command window for the modified path setting to go into effect.

Try:

<input :required="test ? true : false">

Here's a subquery for you!

List<int> IdsToFind = new List<int>() {2, 3, 4};

db.Users
.Where(u => SqlMethods.Like(u.LastName, "%fra%"))
.Where(u =>
    db.CompanyRolesToUsers
    .Where(crtu => IdsToFind.Contains(crtu.CompanyRoleId))
    .Select(crtu =>  crtu.UserId)
    .Contains(u.Id)
)

Regarding this portion of the question:

predicateAnd = predicateAnd.And(c => c.LastName.Contains(
                                TextBoxLastName.Text.Trim()));

I strongly recommend extracting the string from the textbox before authoring the query.

string searchString = TextBoxLastName.Text.Trim();
predicateAnd = predicateAnd.And(c => c.LastName.Contains( searchString));

You want to maintain good control over what gets sent to the database. In the original code, one possible reading is that an untrimmed string gets sent into the database for trimming - which is not good work for the database to be doing.

Try with Resource

File file = new File("Foo.txt");
try (PrintStream ps = new PrintStream(file)) {
   ps.println("Bar");
}
response.setContentType("application/octet-stream");
response.setContentLength((int) file.length());
response.setHeader( "Content-Disposition",
         String.format("attachment; filename=\"%s\"", file.getName()));

OutputStream out = response.getOutputStream();
try (FileInputStream in = new FileInputStream(file)) {
    byte[] buffer = new byte[4096];
    int length;
    while ((length = in.read(buffer)) > 0) {
        out.write(buffer, 0, length);
    }
}
out.flush();

You cannot directly create a table stored as a sequence file and insert text into it. You must do this:

1. Create a table stored as text
2. Insert the text file into the text table
3. Do a CTAS to create the table stored as a sequence file.
4. Drop the text table if desired

Example:

CREATE TABLE test_txt(field1 int, field2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';

LOAD DATA INPATH '/path/to/file.tsv' INTO TABLE test_txt;

CREATE TABLE test STORED AS SEQUENCEFILE
AS SELECT * FROM test_txt;

DROP TABLE test_txt;

From Magnus Lycka answer on a mailing list:

You can skip buffering for a whole python process using "python -u" (or#!/usr/bin/env python -u etc) or by setting the environment variable PYTHONUNBUFFERED.

You could also replace sys.stdout with some other stream like wrapper which does a flush after every call.

class Unbuffered(object):
   def __init__(self, stream):
       self.stream = stream
   def write(self, data):
       self.stream.write(data)
       self.stream.flush()
   def writelines(self, datas):
       self.stream.writelines(datas)
       self.stream.flush()
   def __getattr__(self, attr):
       return getattr(self.stream, attr)

import sys
sys.stdout = Unbuffered(sys.stdout)
print 'Hello'

My solution is a mix of several answers here.

I checked the build server, and Windows7/NET4.0 SDK was already installed, so I did find the path:

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets`

However, on this line:

<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets" />

$(MSBuildExtensionsPath) expands to C:\Program Files\MSBuild which does not have the path.

Therefore what I did was to create a symlink, using this command:

mklink /J "C:\Program Files\MSBuild\Microsoft\VisualStudio" "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio"

This way the $(MSBuildExtensionsPath) expands to a valid path, and no changes are needed in the app itself, only in the build server (perhaps one could create the symlink every build, to make sure this step is not lost and is "documented").

You can use a constant (i.e. a static, final variable) as the parameter for an annotation. As a quick example, I use something like this fairly often:

import org.junit.Test;
import static org.junit.Assert.*;

public class MyTestClass
{
    private static final int TEST_TIMEOUT = 60000; // one minute per test

    @Test(timeout=TEST_TIMEOUT)
    public void testJDK()
    {
        assertTrue("Something is very wrong", Boolean.TRUE);
    }
}

Note that it's possible to pass the TEST_TIMEOUT constant straight into the annotation.

Offhand, I don't recall ever having tried this with an array, so you may be running into some issues with slight differences in how arrays are represented as annotation parameters compared to Java variables? But as for the other part of your question, you could definitely use a constant String without any problems.

EDIT: I've just tried this with a String array, and didn't run into the problem you mentioned - however the compiler did tell me that the "attribute value must be constant" despite the array being defined as public static final String[]. Perhaps it doesn't like the fact that arrays are mutable? Hmm...

If you're a fan of NumPyish syntax, then there's tensor.shape.

In [3]: ar = torch.rand(3, 3)

In [4]: ar.shape
Out[4]: torch.Size([3, 3])

# method-1
In [7]: list(ar.shape)
Out[7]: [3, 3]

# method-2
In [8]: [*ar.shape]
Out[8]: [3, 3]

# method-3
In [9]: [*ar.size()]
Out[9]: [3, 3]

P.S.: Note that tensor.shape is an alias to tensor.size(), though tensor.shape is an attribute of the tensor in question whereas tensor.size() is a function.

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Let's break >> /dev/null 2>&1 statement into parts:

Part 1: >> output redirection

This is used to redirect the program output and append the output at the end of the file. More...

Part 2: /dev/null special file

This is a Pseudo-devices special file.

Command ls -l /dev/null will give you details of this file:

crw-rw-rw-. 1 root root 1, 3 Mar 20 18:37 /dev/null

Did you observe crw? Which means it is a pseudo-device file which is of character-special-file type that provides serial access.

/dev/null accepts and discards all input; produces no output (always returns an end-of-file indication on a read). Reference: Wikipedia

Part 3: 2>&1 file descriptor

Whenever you execute a program, the operating system always opens three files, standard input, standard output, and standard error as we know whenever a file is opened, the operating system (from kernel) returns a non-negative integer called a file descriptor. The file descriptor for these files are 0, 1, and 2, respectively.

So 2>&1 simply says redirect standard error to standard output.

& means whatever follows is a file descriptor, not a filename.

In short, by using this command you are telling your program not to shout while executing.

What is the importance of using 2>&1?

If you don't want to produce any output, even in case of some error produced in the terminal. To explain more clearly, let's consider the following example:

$ ls -l > /dev/null

For the above command, no output was printed in the terminal, but what if this command produces an error:

$ ls -l file_doesnot_exists > /dev/null
ls: cannot access file_doesnot_exists: No such file or directory

Despite I'm redirecting output to /dev/null, it is printed in the terminal. It is because we are not redirecting error output to /dev/null, so in order to redirect error output as well, it is required to add 2>&1:

$ ls -l file_doesnot_exists > /dev/null 2>&1

http.request docs contains example how to receive body of the response through handling data event:

var options = {
  host: 'www.google.com',
  port: 80,
  path: '/upload',
  method: 'POST'
};

var req = http.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

http.get does the same thing as http.request except it calls req.end() automatically.

var options = {
  host: 'www.google.com',
  port: 80,
  path: '/index.html'
};

http.get(options, function(res) {
  console.log("Got response: " + res.statusCode);

  res.on("data", function(chunk) {
    console.log("BODY: " + chunk);
  });
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});

Let's add another solution one to the bunch.

Adding a unique string at the end is a perfect solution.

example.jpg?646413154

Following solution extends this method and provides both the caching capability and fetch a new version when the image is updated.

When the image is updated, the filemtime will be changed.

<?php
$filename = "path/to/images/example.jpg";
$filemtime = filemtime($filename);
?>

Now output the image:

<img src="images/example.jpg?<?php echo $filemtime; ?>" >

Using MVVM Light Toolkit:

Assuming that there is an Exit command in view model:

ICommand _exitCommand;
public ICommand ExitCommand
{
    get
    {
        if (_exitCommand == null)
            _exitCommand = new RelayCommand<object>(call => OnExit());
        return _exitCommand;
    }
}

void OnExit()
{
     var msg = new NotificationMessageAction<object>(this, "ExitApplication", (o) =>{});
     Messenger.Default.Send(msg);
}

This is received in the view:

Messenger.Default.Register<NotificationMessageAction<object>>(this, (m) => if (m.Notification == "ExitApplication")
{
     Application.Current.Shutdown();
});

On the other hand, I handle Closing event in MainWindow, using the instance of ViewModel:

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{ 
    if (((ViewModel.MainViewModel)DataContext).CancelBeforeClose())
        e.Cancel = true;
}

CancelBeforeClose checks the current state of view model and returns true if closing should be stopped.

Hope it helps someone.

The Java Generics FAQ and therefore also cletus' answer sound like there is no point in having Class<List<T>>, however the real problem is that this is extremely dangerous:

@SuppressWarnings("unchecked")
Class<List<String>> stringListClass = (Class<List<String>>) (Class<?>) List.class;

List<Integer> intList = new ArrayList<>();
intList.add(1);
List<String> stringList = stringListClass.cast(intList);
// Surprise!
String firstElement = stringList.get(0);

The cast() makes it look as if it is safe, but in reality it is not safe at all.

Though I don't get where there can't be List<?>.class = Class<List<?>> since this would be pretty helpful when you have a method which determines the type based on the generic type of a Class argument.

For getClass() there is JDK-6184881 requesting to switch to using wildcards, however it does not look like this change will be performed (very soon) since it is not compatible with previous code (see this comment).

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator

And another link here

AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).

Please install http://asepsis.binaryage.com/ and then reboot your mac.

ASEPSIS redirect all .DS_Store on your mac to /usr/local/.dscage

After that, You could delete recursively all .DS_Store from your mac.

find ~ -name ".DS_Store" -delete
or
find <your path> -name ".DS_Store" -delete

You should repeat procedure after each Mac major update.

Also you can setup extJs writer with encode: true and it will send data regularly (and, hence, you will be able to retrieve data via $_POST and $_GET).

... the values will be sent as part of the request parameters as opposed to a raw post (via docs for encode config of Ext.data.writer.Json)

UPDATE

Also docs say that:

The encode option should only be set to true when a root is defined

So, probably, writer's root config is required.

You don't need the CELL() part of your formulas:

=INDIRECT(ADDRESS(B1,B2))

or

=OFFSET($A$1, B1-1,B2-1)

will both work. Note that both INDIRECT and OFFSET are volatile functions. Volatile functions can slow down calculation because they are calculated at every single recalculation.
