Or if your exception is thrown from the constructor of a class:

@Rule
public ExpectedException exception = ExpectedException.none();

@Test
public void myTest() {    

    exception.expect(MyException.class);
    CustomClass myClass= mock(CustomClass.class);
    doThrow(new MyException("constructor failed")).when(myClass);  

}

You can use the clearfix to do "layout preserving" the same way overflow: hidden does.

.clearfix:before,
.clearfix:after {
    content: ".";    
    display: block;    
    height: 0;    
    overflow: hidden; 
}
.clearfix:after { clear: both; }
.clearfix { zoom: 1; } /* IE < 8 */

add class="clearfix" class to the parent, and remove overflow: hidden;

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

If you have PowerShell 5.0 or higher (pre-installed with Windows 10 and Windows Server 2016):

powershell Expand-Archive your.zip -DestinationPath your_destination

char ch='"';

System.out.println(ch + "String" + ch);

Or

System.out.println('"' + "ASHISH" + '"');

Updating ReportViewer should works. Use below instruction to install updated ReportViewer from Nuget Package Manager console.

Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms

Just add below assembly reference in your aspx file.

Here, 15.0.0.0 is the version number of the ReportViewerControl.WebForms that was installed in my VS. Please check Reference of the Solution to confirm the version number. No need to add PublicTokens (if multiple installation exists, it may creates trouble again).

Assuming you are using VSTS run vsts-npm-auth -config .npmrc to generate new .npmrc file with the auth token

For all textbox :

$(':text').blur()

There are two steps to fix this.

First edit phpMyAdmin/libraries/DatabaseInterface.class.php

Change:

    if (PMA_MYSQL_INT_VERSION >  50503) {
        $default_charset = 'utf8mb4';
        $default_collation = 'utf8mb4_general_ci';
    } else {
        $default_charset = 'utf8';
        $default_collation = 'utf8_general_ci';
    }

To:

    //if (PMA_MYSQL_INT_VERSION >  50503) {
    //    $default_charset = 'utf8mb4';
    //    $default_collation = 'utf8mb4_general_ci';
    //} else {
        $default_charset = 'utf8';
        $default_collation = 'utf8_general_ci';
    //}

Then delete this cookie from your browser "pma_collation_connection".
Or delete all Cookies.

Then restart your phpMyAdmin.

(It would be nice if phpMyAdmin allowed you to set the charset and collation per server in the config.inc.php)

You could always do

if (str == null || str.equals(null))

This will first check the object reference and then check the object itself providing the reference isnt null.

Like edg indicated, you'll need a more complex algorithm to handle special names (this is probably why many places force everything to upper case).

Something like this untested c# should handle the simple case you requested:

public string SentenceCase(string input)
{
    return input(0, 1).ToUpper + input.Substring(1).ToLower;
}

UIActionSheet is deprecated in iOS 8.

I am using following:

// Create the AlertController
let actionSheetController = UIAlertController(title: "Please select", message: "How you would like to utilize the app?", preferredStyle: .ActionSheet)

// Create and add the Cancel action
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
    // Just dismiss the action sheet
}
actionSheetController.addAction(cancelAction)

// Create and add first option action
let takePictureAction = UIAlertAction(title: "Consumer", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_customer", sender: self)
}
actionSheetController.addAction(takePictureAction)

// Create and add a second option action
let choosePictureAction = UIAlertAction(title: "Service provider", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_provider", sender: self)
}
actionSheetController.addAction(choosePictureAction)

// We need to provide a popover sourceView when using it on iPad
actionSheetController.popoverPresentationController?.sourceView = sender as UIView

// Present the AlertController
self.presentViewController(actionSheetController, animated: true, completion: nil)

SELECT c1, c2, c3, ... INTO @v1, @v2, @v3,... FROM table_name WHERE condition;

In Case of password also we need to pass one more parameter

redis-cli -h host -p port -a password

If you don't have non-ASCII characters (codepoints 128 and above) in your file, UTF-8 without BOM is the same as ASCII, byte for byte - so Notepad++ will guess wrong.

What you need to do is to specify the character encoding when serving the AJAX response - e.g. with PHP, you'd do this:

header('Content-Type: application/json; charset=utf-8');

The important part is to specify the charset with every JS response - else IE will fall back to user's system default encoding, which is wrong most of the time.

You can do it like this, and no need to dedicate variable:

Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");

Or a little simplified:

MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");

It works only - after the menu created.

You can create temp stored procedures like:

create procedure #mytemp as
begin
   select getdate() into #mytemptable;
end

in an SQL script, but not functions. You could have the proc store it's result in a temp table though, then use that information later in the script ..

Yes. For that ensure that you declare the worksheet

For example

Previous Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet3")

    Debug.Print ws.Cells(23, 4).Value
End Sub

New Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet4")

    Debug.Print ws.Cells(23, 4).Value
End Sub

SimpleORM, because it is straight-forward and no-magic. It defines all meta data structures in Java code and is very flexible.

SimpleORM provides similar functionality to Hibernate by mapping data in a relational database to Java objects in memory. Queries can be specified in terms of Java objects, object identity is aligned with database keys, relationships between objects are maintained and modified objects are automatically flushed to the database with optimistic locks.

But unlike Hibernate, SimpleORM uses a very simple object structure and architecture that avoids the need for complex parsing, byte code processing etc. SimpleORM is small and transparent, packaged in two jars of just 79K and 52K in size, with only one small and optional dependency (Slf4j). (Hibernate is over 2400K plus about 2000K of dependent Jars.) This makes SimpleORM easy to understand and so greatly reduces technical risk.

You can convert yourInt to bytes by using a ByteBuffer like this:

return ByteBuffer.allocate(4).putInt(yourInt).array();

Beware that you might have to think about the byte order when doing so.

If your application mainly tethers web apis, or other io channels, give or take a user interface, node.js may be a fair pick for you, especially if you want to squeeze out the most scalability, or, if your main language in life is javascript (or javascript transpilers of sorts). If you build microservices, node.js is also okay. Node.js is also suitable for any project that is small or simple.

Its main selling point is it allows front-enders take responsibility for back-end stuff rather than the typical divide. Another justifiable selling point is if your workforce is javascript oriented to begin with.

Beyond a certain point however, you cannot scale your code without terrible hacks for forcing modularity, readability and flow control. Some people like those hacks though, especially coming from an event-driven javascript background, they seem familiar or forgivable.

In particular, when your application needs to perform synchronous flows, you start bleeding over half-baked solutions that slow you down considerably in terms of your development process. If you have computation intensive parts in your application, tread with caution picking (only) node.js. Maybe http://koajs.com/ or other novelties alleviate those originally thorny aspects, compared to when I originally used node.js or wrote this.

Here is how I understood not just what virtual functions are, but why they're required:

Let's say you have these two classes:

class Animal
{
    public:
        void eat() { std::cout << "I'm eating generic food."; }
};

class Cat : public Animal
{
    public:
        void eat() { std::cout << "I'm eating a rat."; }
};

In your main function:

Animal *animal = new Animal;
Cat *cat = new Cat;

animal->eat(); // Outputs: "I'm eating generic food."
cat->eat();    // Outputs: "I'm eating a rat."

So far so good, right? Animals eat generic food, cats eat rats, all without virtual.

Let's change it a little now so that eat() is called via an intermediate function (a trivial function just for this example):

// This can go at the top of the main.cpp file
void func(Animal *xyz) { xyz->eat(); }

Now our main function is:

Animal *animal = new Animal;
Cat *cat = new Cat;

func(animal); // Outputs: "I'm eating generic food."
func(cat);    // Outputs: "I'm eating generic food."

Uh oh... we passed a Cat into func(), but it won't eat rats. Should you overload func() so it takes a Cat*? If you have to derive more animals from Animal they would all need their own func().

The solution is to make eat() from the Animal class a virtual function:

class Animal
{
    public:
        virtual void eat() { std::cout << "I'm eating generic food."; }
};

class Cat : public Animal
{
    public:
        void eat() { std::cout << "I'm eating a rat."; }
};

Main:

func(animal); // Outputs: "I'm eating generic food."
func(cat);    // Outputs: "I'm eating a rat."

Done.

Normally jQuery selectors do not search within the "text nodes" in the DOM. However if you use the .contents() function, text nodes will be included, then you can use the nodeType property to filter only the text nodes, and the nodeValue property to search the text string.

    $('*', 'body')
        .andSelf()
        .contents()
        .filter(function(){
            return this.nodeType === 3;
        })
        .filter(function(){
            // Only match when contains 'simple string' anywhere in the text
            return this.nodeValue.indexOf('simple string') != -1;
        })
        .each(function(){
            // Do something with this.nodeValue
        });

I face this issue when I was Building my Flutter Application. This error is due to the gradle version that you are using in your Android Project. Follow the below steps:

• Install jdk version 14.0.2 from https://www.oracle.com/java/technologies/javase-jdk14-downloads.html .

• If using Windows open C:\Program Files\Java\jdk-14.0.2\bin , Copy the Path and now update the path ( Reffer to this article for updating the path : https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/ .

• Open the Project that you are working on [Your Project]\android\gradle\wrapper\gradle-wrapper.properties and now Replace the distributionUrl with the below line:

distributionUrl = https://services.gradle.org/distributions/gradle-6.3-all.zip

Now Save the File (Ctrl + S), Go to the console and run the command

flutter run

It will take some time, but the issue that you were facing will be solved.

Every time you execute

Random random = new Random (15);

It does not matter if you execute it millions of times, you will always use the same seed.

If you use

Random random = new Random ();

You get different random number sequence, if a hacker guesses the seed and your algorithm is related to the security of your system - your algorithm is broken. I you execute mult. In this constructor the seed is specified by the system clock and if several instances are created in a very short period of time (milliseconds) it is possible that they may have the same seed.

If you need safe random numbers you must use the class

System.Security.Cryptography.RNGCryptoServiceProvider

public static int Next(int min, int max)
{
    if(min >= max)
    {
        throw new ArgumentException("Min value is greater or equals than Max value.");
    }
    byte[] intBytes = new byte[4];
    using(RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider())
    {
        rng.GetNonZeroBytes(intBytes);
    }
    return  min +  Math.Abs(BitConverter.ToInt32(intBytes, 0)) % (max - min + 1);
}

Usage:

int randomNumber = Next(1,100);

with open(filename, 'a') as f:
    df.to_csv(f, header=f.tell()==0)

• Create file unless exists, otherwise append
• Add header if file is being created, otherwise skip it

function isNumber(n) {
    return (n===n+''||n===n-0) && n*0==0 && /\S/.test(n);
}

Explanations:

(n===n-0||n===n+'') verifies if n is a number or a string (discards arrays, boolean, date, null, ...). You can replace (n===n-0||n===n+'') by n!==undefined && n!==null && (n.constructor===Number||n.constructor===String): significantly faster but less concise.

n*0==0 verifies if n is a finite number as isFinite(n) does. If you need to check strings that represent negative hexadecimal, just replace n*0==0 by something like n.toString().replace(/^\s*-/,'')*0==0.
It costs a little of course, so if you don't need it, don't use it.

/\S/.test(n) discards empty strings or strings, that contain only white-spaces (necessary since isFinite(n) or n*0==0 return a false positive in this case). You can reduce the number of call to .test(n) by using (n!=0||/0/.test(n)) instead of /\S/.test(n), or you can use a slightly faster but less concise test such as (n!=0||(n+'').indexOf('0')>=0): tiny improvement.

You don't really need a sub-select:

SELECT a, COUNT(*) AS b,
   SUM( CASE WHEN c = 'const' THEN 1 ELSE 0 END ) as d,
   from t group by a order by b desc

Ok, I found this post very interesting and I would like to share some of my knowledge on creating a query. Thanks for this Fluffeh. Others who may read this and may feel that I'm wrong are 101% free to edit and criticise my answer. (Honestly, I feel very thankful for correcting my mistake(s).)

I'll be posting some of the frequently asked questions in MySQL tag.

Trick No. 1 (rows that matches to multiple conditions)

Given this schema

CREATE TABLE MovieList
(
    ID INT,
    MovieName VARCHAR(25),
    CONSTRAINT ml_pk PRIMARY KEY (ID),
    CONSTRAINT ml_uq UNIQUE (MovieName)
);

INSERT INTO MovieList VALUES (1, 'American Pie');
INSERT INTO MovieList VALUES (2, 'The Notebook');
INSERT INTO MovieList VALUES (3, 'Discovery Channel: Africa');
INSERT INTO MovieList VALUES (4, 'Mr. Bean');
INSERT INTO MovieList VALUES (5, 'Expendables 2');

CREATE TABLE CategoryList
(
    MovieID INT,
    CategoryName VARCHAR(25),
    CONSTRAINT cl_uq UNIQUE(MovieID, CategoryName),
    CONSTRAINT cl_fk FOREIGN KEY (MovieID) REFERENCES MovieList(ID)
);

INSERT INTO CategoryList VALUES (1, 'Comedy');
INSERT INTO CategoryList VALUES (1, 'Romance');
INSERT INTO CategoryList VALUES (2, 'Romance');
INSERT INTO CategoryList VALUES (2, 'Drama');
INSERT INTO CategoryList VALUES (3, 'Documentary');
INSERT INTO CategoryList VALUES (4, 'Comedy');
INSERT INTO CategoryList VALUES (5, 'Comedy');
INSERT INTO CategoryList VALUES (5, 'Action');

QUESTION

Find all movies that belong to at least both Comedy and Romance categories.

Solution

This question can be very tricky sometimes. It may seem that a query like this will be the answer:-

SELECT  DISTINCT a.MovieName
FROM    MovieList a
        INNER JOIN CategoryList b
            ON a.ID = b.MovieID
WHERE   b.CategoryName = 'Comedy' AND
        b.CategoryName = 'Romance'

SQLFiddle Demo

which is definitely very wrong because it produces no result. The explanation of this is that there is only one valid value of CategoryName on each row. For instance, the first condition returns true, the second condition is always false. Thus, by using AND operator, both condition should be true; otherwise, it will be false. Another query is like this,

SELECT  DISTINCT a.MovieName
FROM    MovieList a
        INNER JOIN CategoryList b
            ON a.ID = b.MovieID
WHERE   b.CategoryName IN ('Comedy','Romance')

SQLFiddle Demo

and the result is still incorrect because it matches to record that has at least one match on the categoryName. The real solution would be by counting the number of record instances per movie. The number of instance should match to the total number of the values supplied in the condition.

SELECT  a.MovieName
FROM    MovieList a
        INNER JOIN CategoryList b
            ON a.ID = b.MovieID
WHERE   b.CategoryName IN ('Comedy','Romance')
GROUP BY a.MovieName
HAVING COUNT(*) = 2

Trick No. 2 (maximum record for each entry)

Given schema,

CREATE TABLE Software
(
    ID INT,
    SoftwareName VARCHAR(25),
    Descriptions VARCHAR(150),
    CONSTRAINT sw_pk PRIMARY KEY (ID),
    CONSTRAINT sw_uq UNIQUE (SoftwareName)  
);

INSERT INTO Software VALUES (1,'PaintMe','used for photo editing');
INSERT INTO Software VALUES (2,'World Map','contains map of different places of the world');
INSERT INTO Software VALUES (3,'Dictionary','contains description, synonym, antonym of the words');

CREATE TABLE VersionList
(
    SoftwareID INT,
    VersionNo INT,
    DateReleased DATE,
    CONSTRAINT sw_uq UNIQUE (SoftwareID, VersionNo),
    CONSTRAINT sw_fk FOREIGN KEY (SOftwareID) REFERENCES Software(ID)
);

INSERT INTO VersionList VALUES (3, 2, '2009-12-01');
INSERT INTO VersionList VALUES (3, 1, '2009-11-01');
INSERT INTO VersionList VALUES (3, 3, '2010-01-01');
INSERT INTO VersionList VALUES (2, 2, '2010-12-01');
INSERT INTO VersionList VALUES (2, 1, '2009-12-01');
INSERT INTO VersionList VALUES (1, 3, '2011-12-01');
INSERT INTO VersionList VALUES (1, 2, '2010-12-01');
INSERT INTO VersionList VALUES (1, 1, '2009-12-01');
INSERT INTO VersionList VALUES (1, 4, '2012-12-01');

QUESTION

Find the latest version on each software. Display the following columns: SoftwareName,Descriptions,LatestVersion (from VersionNo column),DateReleased

Solution

Some SQL developers mistakenly use MAX() aggregate function. They tend to create like this,

SELECT  a.SoftwareName, a.Descriptions,
        MAX(b.VersionNo) AS LatestVersion, b.DateReleased
FROM    Software a
        INNER JOIN VersionList b
            ON a.ID = b.SoftwareID
GROUP BY a.ID
ORDER BY a.ID

SQLFiddle Demo

(most RDBMS generates a syntax error on this because of not specifying some of the non-aggregated columns on the group by clause) the result produces the correct LatestVersion on each software but obviously the DateReleased are incorrect. MySQL doesn't support Window Functions and Common Table Expression yet as some RDBMS do already. The workaround on this problem is to create a subquery which gets the individual maximum versionNo on each software and later on be joined on the other tables.

SELECT  a.SoftwareName, a.Descriptions,
        b.LatestVersion, c.DateReleased
FROM    Software a
        INNER JOIN
        (
            SELECT  SoftwareID, MAX(VersionNO) LatestVersion
            FROM    VersionList
            GROUP BY SoftwareID
        ) b ON a.ID = b.SoftwareID
        INNER JOIN VersionList c
            ON  c.SoftwareID = b.SoftwareID AND
                c.VersionNO = b.LatestVersion
GROUP BY a.ID
ORDER BY a.ID

SQLFiddle Demo (the answer)

So that was it. I'll be posting another soon as I recall any other FAQ on MySQL tag. Thank you for reading this little article. I hope that you have atleast get even a little knowledge from this.

Here is combined solution for purging Core Data.

- (void)deleteAllObjectsInCoreData
{
    NSArray *allEntities = self.managedObjectModel.entities;
    for (NSEntityDescription *entityDescription in allEntities)
    {
        NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
        [fetchRequest setEntity:entityDescription];

        fetchRequest.includesPropertyValues = NO;
        fetchRequest.includesSubentities = NO;

        NSError *error;
        NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error];

        if (error) {
                NSLog(@"Error requesting items from Core Data: %@", [error localizedDescription]);
            }

Using boost:

#include <boost/algorithm/hex.hpp>

std::string s("tralalalala");
std::string result;
boost::algorithm::hex(s.begin(), s.end(), std::back_inserter(result));

I really don't know what was so hard about this question, but I managed to do it this way:

[myStringContainingInt intValue];

It should be noted that you can also do:

myStringContainingInt.intValue;

Surely using array_map and if using a container implementing ArrayAccess to derive objects is just a smarter, semantic way to go about this?

Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.

For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN() clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.

<?php

$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);

vs

<?php

$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
    $arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);

If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr you could always $arr = array_map and be explicit.

Try this one-

<script>
    (function($){
      $(document).on('contextmenu', 'img', function() {
          return false;
      })
    })(jQuery);
  </script>

For Python 3:

pip3 install python-dateutil

$ file=${$(basename $file_path)%.*}

Check this code,

    public void share(String subject,String text) {
     final Intent intent = new Intent(Intent.ACTION_SEND);

String score=1000;
     intent.setType("text/plain");
     intent.putExtra(Intent.EXTRA_SUBJECT, score);
     intent.putExtra(Intent.EXTRA_TEXT, text);

     startActivity(Intent.createChooser(intent, getString(R.string.share)));
}

You can paste it like this:

= "2010-12-20" - 180

And don't forget to format the cell as a Date [CTRL]+[F1] / Number Tab

For newer versions (such as Visual Studio 2017)

• Select the window you want to duplicate.
• Go to the window tab and click on split at the top of the list.
• When you are done, click it again to toggle it off.

I had the same error in Chrome. The Chrome console told me that the error was in the 1st line of the HTML file.

It was actually in the .js file. So watch out for setValidNou(1060, $(this).val(), 0') error types.

On the 1st of July 2012, a leap second was added to the current UTC-time to compensate for the slowing rotation of the earth due to the tides. When running ntp (or ntpd) this second was added to your computer's/server's clock. MySQLd does not seem to like this extra second on some OS'es, and yields a high CPU load. The quick fix is (as root):

$ /etc/init.d/ntpd stop
$ date -s "`date`"
$ /etc/init.d/ntpd start

Mention has been made that before .NET 4.5 the property on the request to access its ServicePointManager was not available.

Here is .NET 4.0 code that will give you access to the ServicePoint on a per-request basis. It doesn't give you access to the per-request callback, but it should let you find out more details about the problem. Just access the scvPoint.Certificate (or ClientCertificate if you prefer) properties.

WebRequest request = WebRequest.Create(uri);

// oddity: these two .Address values are not necessarily the same!
//  The service point appears to be related to the .Host, not the Uri itself.
//  So, check the .Host vlaues before fussing in the debugger.
//
ServicePoint svcPoint = ServicePointManager.FindServicePoint(uri);
if (null != svcPoint)
{
    if (!request.RequestUri.Host.Equals(svcPoint.Address.Host, StringComparison.OrdinalIgnoreCase))
    {
        Debug.WriteLine(".Address              == " + request.RequestUri.ToString());
        Debug.WriteLine(".ServicePoint.Address == " + svcPoint.Address.ToString());
    }
    Debug.WriteLine(".IssuerName           == " + svcPoint.Certificate.GetIssuerName());
}

Point A: Don't use list as a variable name Point B: You don't need the [0] just

print(list[x])

if grep -q SomeString "$File"; then
  Some Actions # SomeString was found
fi

You don't need [[ ]] here. Just run the command directly. Add -q option when you don't need the string displayed when it was found.

The grep command returns 0 or 1 in the exit code depending on the result of search. 0 if something was found; 1 otherwise.

$ echo hello | grep hi ; echo $?
1
$ echo hello | grep he ; echo $?
hello
0
$ echo hello | grep -q he ; echo $?
0

You can specify commands as an condition of if. If the command returns 0 in its exitcode that means that the condition is true; otherwise false.

$ if /bin/true; then echo that is true; fi
that is true
$ if /bin/false; then echo that is true; fi
$

As you can see you run here the programs directly. No additional [] or [[]].

In combination with lists, dicts and sets, there are also another interesting python objects, OrderedDicts.

Ordered dictionaries are just like regular dictionaries but they remember the order that items were inserted. When iterating over an ordered dictionary, the items are returned in the order their keys were first added.

OrderedDicts could be useful when you need to preserve the order of the keys, for example working with documents: It's common to need the vector representation of all terms in a document. So using OrderedDicts you can efficiently verify if a term has been read before, add terms, extract terms, and after all the manipulations you can extract the ordered vector representation of them.

Unless your app is using some special encryption you can simply add Boolean a key to your Info.plist with name ITSAppUsesNonExemptEncryption and value NO.

If your app is using custom encryption then you will need to provide extra legal documents and go through a review of your encryption before being able to select builds.

If you continue with selecting that version for testing, it will ask for the compliance information manually. Choosing "No" presents you with the plist recommendation above.

This is change has been announced in the 2015 WWDC, but I guess it has been enforced only very recently. See this and this for a transcript of the WWDC session related to the export compliance, just to a text search for "export".

There are other similar questions on SO, see:

• ITSAppUsesNonExemptEncryption export compliance while internal testing?
• Cannot select latest uploaded version to add to testflight
• ITSAppUsesNonExemptEncryption Cordova Build

See the swagger-api/swagger-codegen project on GitHub ; the project README shows how to use it to generate static HTML. See Generating static html api documentation.

If you want to view the swagger.json you can install the Swagger UI and run it. You just deploy it on a web server (the dist folder after you clone the repo from GitHub) and view the Swagger UI in your browser. It's a JavaScript app.

if you have error in Sqlite built in python you can use Conda to solve this conflict

conda install sqlite

In my case I had just renamed the Mysql user which was going to change his password on a gui based db tool (DbVisualizer). The terminal in which I tried to 'SET PASSWORD' did not work(MySQL Error #1133).

However this answer worked for me, even after changing the password the 'SET PASSWORD' command did not work yet.

After closing the terminal and opening new one the command worked very well.

Another workaround that, depends on the case, it could be useful: creating another bash that inherites the exported variable. It is a particular case of @Keith Thompson answer, will all of those drawbacks.

export.bash:

# !/bin/bash
export VAR="HELLO, VARIABLE"
bash

Now:

./export.bash
echo $VAR

No, you need to wrap your TextBlock in a Border. Example:

<Border BorderThickness="1" BorderBrush="Black">
    <TextBlock ... />
</Border>

Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:

<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Black" />
</Style>

<Border Style="{StaticResource notCalledBorder}">
    <TextBlock ... />
</Border>

Most importantly you need to mount the drive

net use z: \\yourserver\sharename

Of course, you need to make sure that the account the batch file runs under has permission to access the share. If you are doing this by using a Scheduled Task, you can choose the account by selecting the task, then:

• right click Properties
• click on General tab
• change account under

"When running the task, use the following user account:" That's on Windows 7, it might be slightly different on different versions of Windows.

Then run your batch script with the following changes

copy "z:\FolderName" "C:\TEST_BACKUP_FOLDER"

You can use Carbon::createFromTimestamp

BLADE

{{ \Carbon\Carbon::createFromTimestamp(strtotime($user->from_date))->format('d-m-Y')}}

It means that len is not set using the default constructor. while the demo class is being constructed. For instance:

class Demo{
    int foo;
public:
    Demo(){ foo = 1;}
};

Would first place a value in foo before setting it to 1. It's slightly faster and more efficient.

basically the to_char(sysdate,'DDD') returns no of days from 1-jan-yyyy to sysdate so that if subtract two dates it will return that,you will get difference between two dates

select to_char(sysdate,'DDD') -to_char(to_date('19-08-1995','dd-mm-yyyy'),'DDD') from dual;

1. Working on IIS 7.5 and Windows 7 i couldnt give permission APPPOOL/Mypool
2. IUSR and IIS_IUSRS permissions not working for me

3. I got to problem this way:

   -Created console application with C#
   -This appliaction using createeventsource like this

   if(!System.Diagnostics.EventLog.SourceExists(sourceName)) System.Diagnostics.EventLog.CreateEventSource(sourceName,logName);

   -Build solution and get .exe file

   -Run exe as administator.This create log file.

NOTE: Dont remember Event viewer must be refresh for see the log.

I hope this solution helps someone :)

ES6

Matrix m with size 3 rows and 5 columns (remove .fill(0) to not init by zero)

[...Array(3)].map(x=>Array(5).fill(0))       

let Array2D = (r,c) => [...Array(r)].map(x=>Array(c).fill(0));

let m = Array2D(3,5);

m[1][0] = 2;  // second row, first column
m[2][4] = 8;  // last row, last column

// print formated array
console.log(JSON.stringify(m)

Here are 3 ways to do it

• 1 : On your MaterialApp set debugShowCheckedModeBanner to false.

   MaterialApp(
     debugShowCheckedModeBanner: false
   )
  

  The slow banner will also automatically be removed on release build.

• 2 : If you are using Android Studio, you can find the option in the Flutter Inspector tab --> More Actions.

• 3 : There is also another way for removing the "debug" banner from the flutter app. Now after new release there is no "debugShowCheckedModeBanner: false," code line in main. dart file. So I think these methods are effective:

  --> If you are using VS Code, then install "Dart DevTools" from extensions. After installation, you can easily find "Dart DevTools" text icon at the bottom of VS Code. When you click on that text icon, a link will be open in google chrome. From that link page, you can easily remove the banner by just tapping on the banner icon as shown.

For more info: How_to_remove_debug_banner_in_flutter_on_android_emulator

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

(Tested for pandas 1.0.5)
Based on @athlonshi answer (it had ValueError: could not convert string to float: 'big', on C column), full working example without warning:

import pandas as pd
from sklearn.preprocessing import MinMaxScaler
scale = preprocessing.MinMaxScaler()

df = pd.DataFrame({
           'A':[14.00,90.20,90.95,96.27,91.21],
           'B':[103.02,107.26,110.35,114.23,114.68], 
           'C':['big','small','big','small','small']
         })
print(df)
df[["A","B"]] = pd.DataFrame(scale.fit_transform(df[["A","B"]].values), columns=["A","B"], index=df.index)
print(df)

       A       B      C
0  14.00  103.02    big
1  90.20  107.26  small
2  90.95  110.35    big
3  96.27  114.23  small

          A         B      C
0  0.000000  0.000000    big

This is just a wrap up of Sayan Pal answer in a shorter form, ES5 style :

var Foo = function(){
    this.bar = undefined;
    this.buzz = undefined;
}

var foo = Object.assign(new Foo(),{
    bar: "whatever",
    buzz: "something else"
});

I like it because it is the closest to the very neat object initialisation in .Net:

var foo = new Foo()
{
    bar: "whatever",
    ...

check

System.getProperty("sun.jnu.encoding")

it seems to be the same encoding as the one used in your system's command line.

Make sure you have project_id in the fillable property of your Comment model.

I had the same issue, And this was the reason.

Do you want to find elements that contain "match", or that equal "match"?

This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2):

//*[text()='match']

This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2):

//*[normalize-space(text())='match']

This will find all elements that contain 'match' in the text node value (matches random2 and random3):

//*[contains(text(),'match')]

This XPATH 2.0 solution uses the matches() function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^) or a word boundary (i.e. \W) and terminated by the end of the string (i.e. $) or a word boundary. The third parameter i evaluates the regex pattern case-insensitive. (matches random2)

//*[matches(text(),'(^|\W)match($|\W)','i')]

I was having the same issue with an SVG image included via the IMG tag. It turned out for me that Chrome didn't like there being a blank line directly at the top of the file.

I removed the blank line and my SVG immediately started rendering.

Ctrl+Space : Show Imports

This displays imports as you're typing a non-standard class name provided the proper references have been added to the project.

This works on partial or complete class names as you are typing them or after the fact (Just place the cursor back on the class name with squigglies).

You can un-check the build automatically in Project menu and then build by hand by type Ctrl + B, or clicking an icon the appears to the right of the printer icon.

Like you said remote_repo_url is indeed the IP of the server, and yes it needs to be added on each PC, but it's easier to understand if you create the server first then ask each to clone it.

There's several ways to connect to the server, you can use ssh, http, or even a network drive, each has it's pros and cons. You can refer to the documentation about protocols and how to connect to the server

You can check the rest of chapter 4 for more detailed information, as it's talking about how to set up your own server

You can request a path in this format:

/package/path/to/the/resource.ext

Even the bytes for creating the classes in memory are found this way:

my.Class -> /my/Class.class

and getResource will give you a URL which can be used to retrieve an InputStream.

But... I'd recommend using directly getClass().getResourceAsStream(...) with the same argument, because it returns directly the InputStream and don't have to worry about creating a (probably complex) URL object that has to know how to create the InputStream.

In short: try using getResourceAsStream and some constructor of ImageIcon that uses an InputStream as an argument.

Classloaders

Be careful if your app has many classloaders. If you have a simple standalone application (no servers or complex things) you shouldn't worry. I don't think it's the case provided ImageIcon was capable of finding it.

Edit: classpath

getResource is—as mattb says—for loading resources from the classpath (from your .jar or classpath directory). If you are bundling an app it's nice to have altogether, so you could include the icon file inside the jar of your app and obtain it this way.

You can't wrap that text as it's unbroken without any spaces. You need a JavaScript or server side solution which splits the string after a few characters.

EDIT

You need to add this property in CSS.

word-wrap: break-word;

_.unique no longer works for the current version of Lodash as version 4.0.0 has this breaking change. The functionality of _.unique was splitted into _.uniq, _.sortedUniq, _.sortedUniqBy, and _.uniqBy.

You could use _.uniqBy like this:

_.uniqBy(data, function (e) {
  return e.id;
});

...or like this:

_.uniqBy(data, 'id');

Documentation: https://lodash.com/docs#uniqBy

For older versions of Lodash (< 4.0.0 ):

Assuming that the data should be uniqued by each object's id property and your data is stored in data variable, you can use the _.unique() function like this:

_.unique(data, function (e) {
  return e.id;
});

Or simply like this:

_.uniq(data, 'id');

You need to define height of ul or your div and set overflow equals to auto as below:

<ul style="width: 300px; height: 200px; overflow: auto">
  <li>text</li>
  <li>text</li>

You can connect to psql as below and write your sql queries like you do in a regular postgres function within the block. There, bash variables can be used. However, the script should be strictly sql, even for comments you need to use -- instead of #:

#!/bin/bash
psql postgresql://<user>:<password>@<host>/<db> << EOF
       <your sql queries go here>
EOF

if you have USB internet like me the emulator seems to dislike connection being turned on and off so you may need to restart the emulator

Try this (on the guest machine. i.e. the OS running in the Virtual box):

sudo adduser your-user vboxsf

Now reboot the OS running in the virtual box.

Just in case anyone is trying to achieve this while using jQuery UI, you will also need to refresh the UI checkbox object to reflect the updated value:

$("#option2").prop("checked", true); // Check id option2
$("input[name='radio_options']").button("refresh"); // Refresh button set

Hmmm... faced something like this and it is a known bug ... just add this OutputProperty ..

transformer.setOutputProperty(OutputPropertiesFactory.S_KEY_INDENT_AMOUNT, "8");

You can create a local computer policy on Windows. See the TechNet at http://technet.microsoft.com/en-us/magazine/dd630947

1. Run gpedit.msc to open the Group Policy Editor,
2. Navigate to Computer Configuration | Windows Settings | Scripts (Startup/Shutdown).

For me it happen because i run it with default java version (7) and not with compiled java version (8) used to create this jar.

So i used:

%Java8_64%\bin\java -jar myjar.jar

Instead of java 7 version:

java -jar myjar.jar

Adapted from this answer to a very similar question:

FORFILES /S /D -10 /C "cmd /c IF @isdir == TRUE rd /S /Q @path"

You should run this command from within your d:\study folder. It will delete all subfolders which are older than 10 days.

The /S /Q after the rd makes it delete folders even if they are not empty, without prompting.

I suggest you put the above command into a .bat file, and save it as d:\study\cleanup.bat.

Here is an easy-to-remember script:

DIR="$(dirname "${BASH_SOURCE[0]}")"  # Get the directory name
DIR="$(realpath "${DIR}")"    # Resolve its full path if need be

You can have one application listening on one port for one network interface. Therefore you could have:

1. httpd listening on remotely accessible interface, e.g. 192.168.1.1:80
2. another daemon listening on 127.0.0.1:80

Sample use case could be to use httpd as a load balancer or a proxy.

We need to use HandlerExceptionResolver in that case.

@Component
public class RESTAuthenticationEntryPoint implements AuthenticationEntryPoint {

    @Autowired
    //@Qualifier("handlerExceptionResolver")
    private HandlerExceptionResolver resolver;

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException {
        resolver.resolveException(request, response, null, authException);
    }
}

Also, you need to add in the exception handler class to return your object.

@RestControllerAdvice
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(AuthenticationException.class)
    public GenericResponseBean handleAuthenticationException(AuthenticationException ex, HttpServletResponse response){
        GenericResponseBean genericResponseBean = GenericResponseBean.build(MessageKeys.UNAUTHORIZED);
        genericResponseBean.setError(true);
        response.setStatus(HttpStatus.UNAUTHORIZED.value());
        return genericResponseBean;
    }
}

may you get an error at the time of running a project because of multiple implementations of HandlerExceptionResolver, In that case you have to add @Qualifier("handlerExceptionResolver") on HandlerExceptionResolver

Opera's simple pointer rotation trick works, but it is extremely inefficient in the worst case in running time. Simply imagine a string with many long repetitive runs of characters, ie:

S1 = HELLOHELLOHELLO1HELLOHELLOHELLO2

S2 = HELLOHELLOHELLO2HELLOHELLOHELLO1

The "loop until there's a mismatch, then increment by one and try again" is a horrible approach, computationally.

To prove that you can do the concatenation approach in plain C without too much effort, here is my solution:

  int isRotation(const char* s1, const char* s2) {
        assert(s1 && s2);

        size_t s1Len = strlen(s1);

        if (s1Len != strlen(s2)) return 0;

        char s1SelfConcat[ 2 * s1Len + 1 ];

        sprintf(s1SelfConcat, "%s%s", s1, s1);   

        return (strstr(s1SelfConcat, s2) ? 1 : 0);
}

This is linear in running time, at the expense of O(n) memory usage in overhead.

(Note that the implementation of strstr() is platform-specific, but if particularly brain-dead, can always be replaced with a faster alternative such as the Boyer-Moore algorithm)

I suggest using Vladimir Keleshev's pep257 Python program to check your docstrings against PEP-257 and the Numpy Docstring Standard for describing parameters, returns, etc.

pep257 will report divergence you make from the standard and is called like pylint and pep8.

Yes. You need to use the try/catch block, but no need to catch the Exception. As per the API it will throw NoResultException if there is no result, and its up to you how you want to handle it.

DrawUnusedBalance drawUnusedBalance = null;
try{
drawUnusedBalance = (DrawUnusedBalance)query.getSingleResult()
catch (NoResultException nre){
//Ignore this because as per your logic this is ok!
}

if(drawUnusedBalance == null){
 //Do your logic..
}

When I was first learning Java we had to make Yahtzee and I thought it would be cool to create custom Swing components and containers instead of just drawing everything on one JPanel. The benefit of extending Swing components, of course, is to have the ability to add support for keyboard shortcuts and other accessibility features that you can't do just by having a paint() method print a pretty picture. It may not be done the best way however, but it may be a good starting point for you.

Edit 8/6 - If it wasn't apparent from the images, each Die is a button you can click. This will move it to the DiceContainer below. Looking at the source code you can see that each Die button is drawn dynamically, based on its value.

Here are the basic steps:

1. Create a class that extends JComponent
2. Call parent constructor super() in your constructors
3. Make sure you class implements MouseListener

4. Put this in the constructor:

   enableInputMethods(true);   
   addMouseListener(this);
   

5. Override these methods:

   public Dimension getPreferredSize()  
   public Dimension getMinimumSize()  
   public Dimension getMaximumSize()
   

6. Override this method:

   public void paintComponent(Graphics g)
   

The amount of space you have to work with when drawing your button is defined by getPreferredSize(), assuming getMinimumSize() and getMaximumSize() return the same value. I haven't experimented too much with this but, depending on the layout you use for your GUI your button could look completely different.

And finally, the source code. In case I missed anything.

There is one way that I have used my self. Go to Control Panel\Programs\Turn Windows features on or off then uninstall IIS and all of its components completely. I restart windows but I'm not sure if it's required or not. Then install it again from the same path.

July 2015 - I have concluded that IntelliJ does not support automatically resolving imports with a single function. "Organize imports" simply removes unused imports, it does not resolve unimported types. Control-Space resolves a single unimported type. There does not exist a single action to resolve all types' imports.

I was running the project through Intellij and this got this error after I stopped the running server and restarted it. Killing all the java processes and restarting the app helped.

I'm adding this alternative as I suffered a lot with this issue. I tried all different ways and nothing worked. So, I came up with a workaround for it. It might not be the best solution but it does work -

FYI, I am using Laravel 5.6

if (App::environment('production')) {
    URL::forceScheme('https');
}

production <- It should be replaced with the APP_ENV value in your .env file

I used angular with electron,

In my case, setInterval returns a Nodejs Timer object. which when I called clearInterval(timerobject) it did not work.

I had to get the id first and call to clearInterval

clearInterval(timerobject._id)

I have struggled many hours with this. hope this helps.

This is one of the new features of Java 8, part of JDK Enhancement Proposals 122:

Remove the permanent generation from the Hotspot JVM and thus the need to tune the size of the permanent generation.

The list of all the JEPs that will be included in Java 8 can be found on the JDK8 milestones page.

from Object import Object

or

From Class_Name import Class_name

I have created a simple javascript library that retrieves google spreadsheet data (if they are published) via the JSON api:

https://github.com/mikeymckay/google-spreadsheet-javascript

You can see it in action here:

http://mikeymckay.github.com/google-spreadsheet-javascript/sample.html

You can use $anchorScroll.

Just inject $anchorScroll as a dependency, and call $anchorScroll() whenever you want to scroll to top.

You can use that:

let s: string = "true";
let b: boolean = Boolean(s);

This did the job for me,

import org.apache.commons.lang.StringEscapeUtils;
...
String decodedXML= StringEscapeUtils.unescapeHtml(encodedXML);

or

import org.apache.commons.lang3.StringEscapeUtils;
...
String decodedXML= StringEscapeUtils.unescapeHtml4(encodedXML);

I guess its always better to use the lang3 for obvious reasons. Hope this helps :)

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

You have to create a symlink to your mysql installation if it is not the most recent version of mysql.

This worked for me:

1. Go to the .env file and be sure APP_DEBUG=true
2. Here (in .env file) change reemplace 127.0.0.1 for localhost for check if your DB credential are corrects.
3. Go to the config folder and do. the step #2.

A very relevant article is Debugging Heap corruption with Application Verifier and Debugdiag.

If using Visual Studio 2010 you can right-click on the project for the service, and select properties. Then select the Web tab. Under the Servers section you can configure the URL. There is also a button to create the virtual directory.

You can just reverse your log and just head it for the first result.

git log --pretty=oneline --reverse | head -1

Because QuerySets implement the Python __or__ operator (|), or union, it just works. As you'd expect, the | binary operator returns a QuerySet so order_by(), .distinct(), and other queryset filters can be tacked on to the end.

combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')

Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.

Create your partial view something like:

@model YourModelType
<div>
  <!-- HTML to render your object -->
</div>

Then in your view use:

@Html.Partial("YourPartialViewName", Model)

If you do not want a strongly typed partial view remove the @model YourModelType from the top of the partial view and it will default to a dynamic type.

Update

The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/ in the path below.

@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)

For Bootstrap 4.x use display utilities:

14. is prefix should be used for boolean variables and methods.

    isSet, isVisible, isFinished, isFound, isOpen

This is the naming convention for boolean methods and variables used by Sun for the Java core packages. Using the is prefix solves a common problem of choosing bad boolean names like status or flag. isStatus or isFlag simply doesn't fit, and the programmer is forced to chose more meaningful names.

Setter methods for boolean variables must have set prefix as in:

void setFound(boolean isFound);

There are a few alternatives to the is prefix that fits better in some situations. These are has, can and should prefixes:

boolean hasLicense(); 
boolean canEvaluate(); 
boolean shouldAbort = false;

select id,first_name,gender,age,
rank() over(partition by gender order by age) rank_g
from person

CREATE TABLE person (id int, first_name varchar(20), age int, gender char(1));

INSERT INTO person VALUES (1, 'Bob', 25, 'M');
INSERT INTO person VALUES (2, 'Jane', 20, 'F');
INSERT INTO person VALUES (3, 'Jack', 30, 'M');
INSERT INTO person VALUES (4, 'Bill', 32, 'M');
INSERT INTO person VALUES (5, 'Nick', 22, 'M');
INSERT INTO person VALUES (6, 'Kathy', 18, 'F');
INSERT INTO person VALUES (7, 'Steve', 36, 'M');
INSERT INTO person VALUES (8, 'Anne', 25, 'F');
INSERT INTO person VALUES (9,'AKSH',32,'M');

If you are into following Google's style guide:

Test, [ and [[

[[ ... ]] reduces errors as no path name expansion or word splitting takes place between [[ and ]], and [[ ... ]] allows for regular expression matching where [ ... ] does not.

# This ensures the string on the left is made up of characters in the
# alnum character class followed by the string name.
# Note that the RHS should not be quoted here.
# For the gory details, see
# E14 at https://tiswww.case.edu/php/chet/bash/FAQ
if [[ "filename" =~ ^[[:alnum:]]+name ]]; then
  echo "Match"
fi

# This matches the exact pattern "f*" (Does not match in this case)
if [[ "filename" == "f*" ]]; then
  echo "Match"
fi

# This gives a "too many arguments" error as f* is expanded to the
# contents of the current directory
if [ "filename" == f* ]; then
  echo "Match"
fi

public boolean isNetworkAvailable(Context context) {
    ConnectivityManager connectivityManager = (ConnectivityManager) context
            .getSystemService(context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager
            .getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

Requests natively supports basic auth only with user-pass params, not with tokens.

You could, if you wanted, add the following class to have requests support token based basic authentication:

import requests
from base64 import b64encode

class BasicAuthToken(requests.auth.AuthBase):
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        authstr = 'Basic ' + b64encode(('token:' + self.token).encode('utf-8')).decode('utf-8')
        r.headers['Authorization'] = authstr
        return r

Then, to use it run the following request :

r = requests.get(url, auth=BasicAuthToken(api_token))

An alternative would be to formulate a custom header instead, just as was suggested by other users here.

We can close every window using Application.Exit(); Using this method we can close hidden windows also.

     let webView = UIWebView(frame: view.bounds)
    let targetURL = Bundle.main.url(forResource: "sampleFileName", withExtension: "pdf")
    let request = URLRequest(url: targetURL!)
    webView.loadRequest(request)
    view.addSubview(webView)

line=$((${RANDOM} % $(wc -l < /etc/passwd)))
sed -n "${line}p" /etc/passwd

just with your file instead.

In this example I used the file /etc/password, using the special variable ${RANDOM} (about which I learned here), and the sed expression you had, only difference is that I am using double quotes instead of single to allow the variable expansion.

Hopefully it helps someone: I ran into this error and the cause was wrong permission on the log folder for phpfpm, after changing it so phpfpm could write to it, everything was fine.

THIS IS FOR BEGINNERS,

Python automatically compiles your script to compiled code, so called byte code, before running it.

Running a script is not considered an import and no .pyc will be created.

For example, if you have a script file abc.py that imports another module xyz.py, when you run abc.py, xyz.pyc will be created since xyz is imported, but no abc.pyc file will be created since abc.py isn’t being imported.

If you need to create a .pyc file for a module that is not imported, you can use the py_compile and compileall modules.

The py_compile module can manually compile any module. One way is to use the py_compile.compile function in that module interactively:

>>> import py_compile
>>> py_compile.compile('abc.py')

This will write the .pyc to the same location as abc.py (you can override that with the optional parameter cfile).

You can also automatically compile all files in a directory or directories using the compileall module.

python -m compileall

If the directory name (the current directory in this example) is omitted, the module compiles everything found on sys.path

This error might also occur due to proxy settings, once check that your proxy allow the access to npm commands.

It worked for me quite well.

Well, my code is like yours, with little diferences...

java.io.NotSerializableException can occur when you serialize an inner class instance because:

serializing such an inner class instance will result in serialization of its associated outer class instance as well

Serialization of inner classes (i.e., nested classes that are not static member classes), including local and anonymous classes, is strongly discouraged

Ref: The Serializable Interface

I suspect that you are getting a callback to a UI component from a background thread. I recommend that you make that call using a BackgroundWorker as this is UI thread aware.

For the BackgroundWorker, the main program should be marked as [STAThread].

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.

public static void configureLog4jFromSystemProperties()
{
  final String LOGGER_PREFIX = "log4j.logger.";

  for(String propertyName : System.getProperties().stringPropertyNames())
  {
    if (propertyName.startsWith(LOGGER_PREFIX)) {
      String loggerName = propertyName.substring(LOGGER_PREFIX.length());
      String levelName = System.getProperty(propertyName, "");
      Level level = Level.toLevel(levelName); // defaults to DEBUG
      if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
        logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
        continue;
      }
      logger.info("Setting " + loggerName + " => " + level.toString());
      Logger.getLogger(loggerName).setLevel(level);
    }
  }
}

You may also try Perf4J. Its a neat way of doing what you are looking for, and helps in aggregated performance statistics like mean, minimum, maximum, standard deviation and transactions per second over a set time span. An extract from http://perf4j.codehaus.org/devguide.html:

StopWatch stopWatch = new LoggingStopWatch();

try {
    // the code block being timed - this is just a dummy example
    long sleepTime = (long)(Math.random() * 1000L);
    Thread.sleep(sleepTime);
    if (sleepTime > 500L) {
        throw new Exception("Throwing exception");
    }

    stopWatch.stop("codeBlock2.success", "Sleep time was < 500 ms");
} catch (Exception e) {
    stopWatch.stop("codeBlock2.failure", "Exception was: " + e);
}

Output:

Dependency Injection

If you inject the Bar instance, or a factory that is used for creating the Bar instance (or one of the other 483 ways of doing this), you'd have the access necessary to do perform the test.

Factory Example:

Given a Foo class written like this:

public class Foo {
  private BarFactory barFactory;

  public Foo(BarFactory factory) {
    this.barFactory = factory;
  }

  public void foo() {
    Bar bar = this.barFactory.createBar();
    bar.someMethod();
  }
}

in your test method you can inject a BarFactory like this:

@Test
public void testDoFoo() {
  Bar bar = mock(Bar.class);
  BarFactory myFactory = new BarFactory() {
    public Bar createBar() { return bar;}
  };

  Foo foo = new Foo(myFactory);
  foo.foo();

  verify(bar, times(1)).someMethod();
}

Bonus: This is an example of how TDD can drive the design of your code.

Use the below Power shell command to change the execution timeout (Request Timeout)

Please note that I have given this for default web site, before using these please change the site and then try to use this.

 Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter "system.web/httpRuntime" -name "executionTimeout" -value "00:01:40"

Or, You can use the below C# code to do the same thing

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample {

    private static void Main() {

        using(ServerManager serverManager = new ServerManager()) { 
            Configuration config = serverManager.GetWebConfiguration("Default Web Site");

            ConfigurationSection httpRuntimeSection = config.GetSection("system.web/httpRuntime");
            httpRuntimeSection["executionTimeout"] = TimeSpan.Parse("00:01:40");

            serverManager.CommitChanges();
        }
    }
}

Or, you can use the JavaScript to do this.

var adminManager = new ActiveXObject('Microsoft.ApplicationHost.WritableAdminManager');
adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site";

var httpRuntimeSection = adminManager.GetAdminSection("system.web/httpRuntime", "MACHINE/WEBROOT/APPHOST/Default Web Site");
httpRuntimeSection.Properties.Item("executionTimeout").Value = "00:01:40";

adminManager.CommitChanges();

Or, you can use the AppCmd commands.

appcmd.exe set config "Default Web Site" -section:system.web/httpRuntime /executionTimeout:"00:01:40"

Don't use a service for this. Create a normal application and create a scheduled task to run it.

This is the commonly held best practice. Jon Galloway agrees with me. Or maybe its the other way around. Either way, the fact is that it is not best practices to create a windows service to perform an intermittent task run off a timer.

"If you're writing a Windows Service that runs a timer, you should re-evaluate your solution."

It could also be because you're trying to put in a null value back into the database. So one of your transactions could have nulls in them.

Try something like this

jQuery

$('#toggle_icon').toggle(function() {

    $('#toggle_icon').text('-');
    $('#toggle_text').slideToggle();

}, function() {

    $('#toggle_icon').text('+');
    $('#toggle_text').slideToggle();

});

For short month names use:

string monthName = new DateTime(2010, 8, 1)
    .ToString("MMM", CultureInfo.InvariantCulture);

For long/full month names for Spanish ("es") culture

string fullMonthName = new DateTime(2015, i, 1).ToString("MMMM", CultureInfo.CreateSpecificCulture("es"));

After trying several things, this worked for me:

• use the --publish=0.0.0.0:8080:8080 docker flag
• set the virtualbox network mode to NAT, and don't use any port forwarding

With addresses other than 0.0.0.0 I had no success.

Something like this:

unsigned int getConsoleInput(char **pStrBfr) //pass in pointer to char pointer, returns size of buffer
{
    char * strbfr;
    int c;
    unsigned int i;
    i = 0;
    strbfr = (char*)malloc(sizeof(char));
    if(strbfr==NULL) goto error;
    while( (c = getchar()) != '\n' && c != EOF )
    {
        strbfr[i] = (char)c;
        i++;
        strbfr = (void*)realloc((void*)strbfr,sizeof(char)*(i+1));
        //on realloc error, NULL is returned but original buffer is unchanged
        //NOTE: the buffer WILL NOT be NULL terminated since last
        //chracter came from console
        if(strbfr==NULL) goto error;
    }
    strbfr[i] = '\0';
    *pStrBfr = strbfr; //successfully returns pointer to NULL terminated buffer
    return i + 1; 
    error:
    *pStrBfr = strbfr;
    return i + 1;
}

You can solve like this,

1. Open "Applications Pools",
2. You should right click that you have choosed application pool. Then choose "Advanced Settings".
3. Click three point on the Identity tab then you should choose "LocalSystem" from field of "Built-in-account"

If you do this way, you don't need to create a user in database.

In CSS3 paged media this is possible using position: running() and content: element().

Example from the CSS Generated Content for Paged Media Module draft:

@top-center {
  content: element(heading); 
}

.runner { 
  position: running(heading);
}

.runner can be any element and heading is an arbitrary name for the slot.

EDIT: to clarify, there is basically no browser support so this was mostly meant to be for future reference/in addition to the 'practical answers' given already.

Another way of doing it would be:

stuff = Object.assign(stuff, {$(this).attr('value'):$(this).attr('checked')});

Read more here: Object.assign()

Hint

DataTable table = new DataTable();
table.Columns.Add("Column#1", typeof(int));
table.Columns.Add("Column#2", typeof(string));
table.Rows.Add(5, "Cell1-1");
table.Rows.Add(130, "Cell2-2");

EDIT: Added more

string cellValue = table.Rows[0].GetCellValueByName<string>("Column#2");

public static class DataRowExtensions
{
    public static T GetCellValueByName<T>(this DataRow row, string columnName)
    {
        int index = row.Table.Columns.IndexOf(columnName);
        return (index < 0 || index > row.ItemArray.Count()) 
                  ? default(T) 
                  : (T) row[index];        
    }
}

make your class public access modifier,

just add public keyword infront of your class name

 namespace Test
{
  public  class Delivery
    {
        private string name;
        private string address;
        private DateTime arrivalTime;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }

        public string Address
        {
            get { return address; }
            set { address = value; }
        }

        public DateTime ArrivlaTime
        {
            get { return arrivalTime; }
            set { arrivalTime = value; }
        }

        public string ToString()
        {
            { return name + address + arrivalTime.ToString(); }
        }
    }
}

SOAP (Simple Object Access Protocol) and REST (Representation State Transfer) both are beautiful in their way. So I am not comparing them. Instead, I am trying to depict the picture, when I preferred to use REST and when SOAP.

What is payload?

When data is sent over the Internet, each unit transmitted includes both header information and the actual data being sent. The header identifies the source and destination of the packet, while the actual data is referred to as the payload. In general, the payload is the data that is carried on behalf of an application and the data received by the destination system.

Now, for example, I have to send a Telegram and we all know that the cost of the telegram will depend on some words.

So tell me among below mentioned these two messages, which one is cheaper to send?

<name>Arin</name>

or

"name": "Arin"

I know your answer will be the second one although both representing the same message second one is cheaper regarding cost.

So I am trying to say that, sending data over the network in JSON format is cheaper than sending it in XML format regarding payload.

Here is the first benefit or advantages of REST over SOAP. SOAP only support XML, but REST supports different format like text, JSON, XML, etc. And we already know, if we use Json then definitely we will be in better place regarding payload.

Now, SOAP supports the only XML, but it also has its advantages.

Really! How?

SOAP relies on XML in three ways Envelope – that defines what is in the message and how to process it.

A set of encoding rules for data types, and finally the layout of the procedure calls and responses gathered.

This envelope is sent via a transport (HTTP/HTTPS), and an RPC (Remote Procedure Call) is executed, and the envelope is returned with information in an XML formatted document.

The important point is that one of the advantages of SOAP is the use of the “generic” transport but REST uses HTTP/HTTPS. SOAP can use almost any transport to send the request but REST cannot. So here we got an advantage of using SOAP.

As I already mentioned in above paragraph “REST uses HTTP/HTTPS”, so go a bit deeper on these words.

When we are talking about REST over HTTP, all security measures applied HTTP are inherited, and this is known as transport level security and it secures messages only while it is inside the wire but once you delivered it on the other side you don’t know how many stages it will have to go through before reaching the real point where the data will be processed. And of course, all those stages could use something different than HTTP.So Rest is not safer completely, right?

But SOAP supports SSL just like REST additionally it also supports WS-Security which adds some enterprise security features. WS-Security offers protection from the creation of the message to it’s consumption. So for transport level security whatever loophole we found that can be prevented using WS-Security.

Apart from that, as REST is limited by it's HTTP protocol so it’s transaction support is neither ACID compliant nor can provide two-phase commit across distributed transnational resources.

But SOAP has comprehensive support for both ACID based transaction management for short-lived transactions and compensation based transaction management for long-running transactions. It also supports two-phase commit across distributed resources.

I am not drawing any conclusion, but I will prefer SOAP-based web service while security, transaction, etc. are the main concerns.

Here is the "The Java EE 6 Tutorial" where they have said A RESTful design may be appropriate when the following conditions are met. Have a look.

Hope you enjoyed reading my answer.

context.getPackageManager().getInstalledApplications(PackageManager.GET_META_DATA); Should return the list of all the installed apps but in android 11 it'll only return the list of system apps. To get the list of all the applications(system+user) we need to provide an additional permission to the application i.e

<uses-permission android:name"android.permission.QUERY_ALL_PACKAGES">

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

Here is a good table for printf specifiers. So it should be %hu for unsigned short int.

And link to Wikipedia "C data types" too.

I was able to get SSL working with the following boilerplate code:

var fs = require('fs'),
    http = require('http'),
    https = require('https'),
    express = require('express');

var port = 8000;

var options = {
    key: fs.readFileSync('./ssl/privatekey.pem'),
    cert: fs.readFileSync('./ssl/certificate.pem'),
};

var app = express();

var server = https.createServer(options, app).listen(port, function(){
  console.log("Express server listening on port " + port);
});

app.get('/', function (req, res) {
    res.writeHead(200);
    res.end("hello world\n");
});

If you can cope with the extra dependency then use twisted.log, you don't have to explicitly log errors and also it returns the entire traceback and time to the file or stream.

First of all, input element shouldn't have a closing tag (from http://www.w3.org/TR/html401/interact/forms.html#edef-INPUT : End tag: forbidden ).

Second thing, you need the after(), not append() function.

This will convert an integer to a 2 digit hex string with the 0x prefix:

strHex = "0x%0.2X" % 255

If you are encountering this issue with an application installed via conda, the solution (as stated in this bug report) is simply to install setup-tools with:

conda install setuptools

Use the DateFormat API to convert the String into a Date object, then use the Calendar API to add one day. Let me know if you want specific code examples, and I can update my answer.

In case you want to compress a PDF which contains a lot of selectable text, on Windows you can use NicePDF Compressor - choose "Flate" option. After trying everything (cpdf, pdftk, gs) it finally helped me to compress my 1360 pages PDF from 500 MB down to 10 MB.

Depending on your definition of "special character", I think "[^a-zA-Z0-9]" would probably do the trick. That would find anything that is not a small letter, a capital letter, or a digit.

They often forget that iterator must convert to const_iterator but not the other way around. Here is a way to do that:

template<class T, class Tag = void>
class IntrusiveSlistIterator
   : public std::iterator<std::forward_iterator_tag, T>
{
    typedef SlistNode<Tag> Node;
    Node* node_;

public:
    IntrusiveSlistIterator(Node* node);

    T& operator*() const;
    T* operator->() const;

    IntrusiveSlistIterator& operator++();
    IntrusiveSlistIterator operator++(int);

    friend bool operator==(IntrusiveSlistIterator a, IntrusiveSlistIterator b);
    friend bool operator!=(IntrusiveSlistIterator a, IntrusiveSlistIterator b);

    // one way conversion: iterator -> const_iterator
    operator IntrusiveSlistIterator<T const, Tag>() const;
};

In the above notice how IntrusiveSlistIterator<T> converts to IntrusiveSlistIterator<T const>. If T is already const this conversion never gets used.

RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

Following leppie's answer, why not make MetaData an interface:

public interface IMetaData { }

public class Metadata<DataType> : IMetaData where DataType : struct
{
    private DataType mDataType;
}

The HTML Tidy library is able to fix some malformed XML files. Running your feeds through that before passing them on to the parser may help.

I used awk for this

a="The cat sat on the mat"
test="cat"
awk -v a="$a" -v b="$test" 'BEGIN{print index(a,b)}'

ID % 2 reduces all integer (monetary and numeric are allowed, too) numbers to 0 and 1 effectively.
Read about the modulo operator in the manual.

I agree with Kevin B, the bug report says it all. It sounds like you are trying to make cross-domain ajax calls. If you're not familiar with the same origin policy you can start here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Same_origin_policy_for_JavaScript.

If this is not intended to be a cross-domain ajax call, try making your target url relative and see if the problem goes away. If you're really desperate look into the JSONP, but beware, mayhem lurks. There really isn't much more we can do to help you.

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

Assuming that winrar.exe is in the PATH, then Runtime.exec is capable of finding it, if it is not, you will need to supply the fully qualified path to it, for example, assuming winrar.exe is installed in C:/Program Files/WinRAR you would need to use something like...

p=r.exec("C:/Program Files/WinRAR/winrar x h:\\myjar.jar *.* h:\\new");

Personally, I would recommend that you use ProcessBuilder as it has some additional configuration abilities amongst other things. Where possible, you should also separate your command and parameters into separate String elements, it deals with things like spaces much better then a single String variable, for example...

ProcessBuilder pb = new ProcessBuilder(
    "C:/Program Files/WinRAR/winrar",
    "x",
    "myjar.jar",
    "*.*",
    "new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

Don't forget to read the contents of the InputStream from the process, as failing to do so may stall the process

In selec2 site you can see options. There is "disabled" option for api. You can use like :

$('#foo').select2({
    disabled: true
});

Faster results can be achieved using numpy.where.

For example, with unubtu's setup -

In [76]: df.iloc[np.where(df.A.values=='foo')]
Out[76]: 
     A      B  C   D
0  foo    one  0   0
2  foo    two  2   4
4  foo    two  4   8
6  foo    one  6  12
7  foo  three  7  14

Timing comparisons:

In [68]: %timeit df.iloc[np.where(df.A.values=='foo')]  # fastest
1000 loops, best of 3: 380 µs per loop

In [69]: %timeit df.loc[df['A'] == 'foo']
1000 loops, best of 3: 745 µs per loop

In [71]: %timeit df.loc[df['A'].isin(['foo'])]
1000 loops, best of 3: 562 µs per loop

In [72]: %timeit df[df.A=='foo']
1000 loops, best of 3: 796 µs per loop

In [74]: %timeit df.query('(A=="foo")')  # slowest
1000 loops, best of 3: 1.71 ms per loop

My use case: In my react app, Upon user click there is an API call performed to the backend. Based on the response, new tab is opened with the api response added as params to the new tab URL (in same domain).

The only caveat in my use case is that it takes more for 1 second for the API response to be received. Hence pop-up blocker shows up (if it is active) when opening up URL in a new tab.

To circumvent the above described issue, here is the sample code,

var new_tab=window.open()
axios.get('http://backend-api').then(response=>{
    const url="http://someurl"+"?response"
    new_tab.location.href=url;
}).catch(error=>{
    //catch error
})

Summary: Create an empty tab (as above line 1) and when the API call is completed, you can fill up the tab with the url and skip the popup blocker.

If UAC is enabled on the computer, something like this should work:

If Not WScript.Arguments.Named.Exists("elevate") Then
  CreateObject("Shell.Application").ShellExecute WScript.FullName _
    , """" & WScript.ScriptFullName & """ /elevate", "", "runas", 1
  WScript.Quit
End If

If you really want us to just continue where you left off, you could do:

if (fieldNameElement)
    fieldNameElement.innerHTML = 'some HTML';

You can use Object.keys functionality to get the keys like:

const tempObjects={foo:"bar"}

Object.keys(tempObjects).forEach(obj=>{
   console.log("Key->"+obj+ "value->"+tempObjects[obj]);
});

This worked very well for me

    var ctx = $("#mycanvas");
     var LineGraph = new Chart(ctx, {
        type: 'line',
        data: chartdata});
        LineGraph.destroy();

Use .destroy this to destroy any chart instances that are created. This will clean up any references stored to the chart object within Chart.js, along with any associated event listeners attached by Chart.js. This must be called before the canvas is reused for a new chart.

I've now spent quite some time to figure out how to use this with methods that return values, and I haven't seen any examples so far, I thought it might be useful to add this here:

int foo(int a) {
    // do something with a
    return a;
}

int foo() {
    return foo(0); // here, 0 is a default value for a
}

For those trouble shooting, it is important to know that ng-include requires the url path to be from the app root directory and not from the same directory where the partial.html lives. (whereas partial.html is the view file that the inline ng-include markup tag can be found).

For example:

Correct: div ng-include src=" '/views/partials/tabSlides/add-more.html' ">

Incorrect: div ng-include src=" 'add-more.html' ">

I think those stats show that Python is much slower and uses more memory for those benchmarks - are you sure you're reading them the right way up?

In my experience, which is mostly with writing network- and file-system-bound programs in Python, Python isn't significantly slower in any way that matters. For that kind of work, its benefits outweigh its costs.

How to do it with Oracle SQL Developer: In the Left pane, under the connections you will find "Sequences", right click and select create a new sequence from the context sensitive pop up. Fill out the details: Schema name, sequence_name, properties(start with value, min value, max value, increment value etc.) and click ok. Assuming that you have a table with a key that uses this auto_increment, while inserting in this table just give "your_sequence_name.nextval" in the field that utilizes this property. I guess this should help! :)

Instead Animals == "bird*" Animals = "bird*" should work.

It’s a name for the :: operator in PHP. It literally means "double colon". For some reason they named it in Hebrew. Check your code syntax, and put a :: where appropriate :-)

t.Log() will not show up until after the test is complete, so if you're trying to debug a test that is hanging or performing badly it seems you need to use fmt.

Yes: that was the case up to Go 1.13 (August 2019) included.

And that was followed in golang.org issue 24929

Consider the following (silly) automated tests:

func TestFoo(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)

func TestBar(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(2 * time.Second)

func TestBaz(t *testing.T) {
    t.Parallel()

If I run go test -v, I get no log output until all of TestFoo is done, then no output until all of TestBar is done, and again no more output until all of TestBaz is done.
This is fine if the tests are working, but if there is some sort of bug, there are a few cases where buffering log output is problematic:

• When iterating locally, I want to be able to make a change, run my tests, see what's happening in the logs immediately to understand what's going on, hit CTRL+C to shut the test down early if necessary, make another change, re-run the tests, and so on.
  If TestFoo is slow (e.g., it's an integration test), I get no log output until the very end of the test. This significantly slows down iteration.
• If TestFoo has a bug that causes it to hang and never complete, I'd get no log output whatsoever. In these cases, t.Log and t.Logf are of no use at all.
  This makes debugging very difficult.
• Moreover, not only do I get no log output, but if the test hangs too long, either the Go test timeout kills the test after 10 minutes, or if I increase that timeout, many CI servers will also kill off tests if there is no log output after a certain amount of time (e.g., 10 minutes in CircleCI).
  So now my tests are killed and I have nothing in the logs to tell me what happened.

But for (possibly) Go 1.14 (Q1 2020): CL 127120

testing: stream log output in verbose mode

The output now is:

=== RUN   TestFoo
=== PAUSE TestFoo
=== RUN   TestBar
=== PAUSE TestBar
=== RUN   TestGaz
=== PAUSE TestGaz
=== CONT  TestFoo
    TestFoo: main_test.go:14: hello from foo
=== CONT  TestGaz
=== CONT  TestBar
    TestGaz: main_test.go:38: hello from gaz
    TestBar: main_test.go:26: hello from bar
    TestFoo: main_test.go:14: hello from foo
    TestBar: main_test.go:26: hello from bar
    TestGaz: main_test.go:38: hello from gaz
    TestFoo: main_test.go:14: hello from foo
    TestGaz: main_test.go:38: hello from gaz
    TestBar: main_test.go:26: hello from bar
    TestFoo: main_test.go:14: hello from foo
    TestGaz: main_test.go:38: hello from gaz
    TestBar: main_test.go:26: hello from bar
    TestGaz: main_test.go:38: hello from gaz
    TestFoo: main_test.go:14: hello from foo
    TestBar: main_test.go:26: hello from bar
--- PASS: TestFoo (1.00s)
--- PASS: TestGaz (1.00s)
--- PASS: TestBar (1.00s)
PASS
ok      dummy/streaming-test    1.022s

It is indeed in Go 1.14, as Dave Cheney attests in "go test -v streaming output":

In Go 1.14, go test -v will stream t.Log output as it happens, rather than hoarding it til the end of the test run.

Under Go 1.14 the fmt.Println and t.Log lines are interleaved, rather than waiting for the test to complete, demonstrating that test output is streamed when go test -v is used.

Advantage, according to Dave:

This is a great quality of life improvement for integration style tests that often retry for long periods when the test is failing.
Streaming t.Log output will help Gophers debug those test failures without having to wait until the entire test times out to receive their output.

If i understand your question right then,

Yes you can set style of individual element if its id or name is available,

e.g.

if id available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsById('goButton');

v_obj.setAttribute('style','color:red;background:none');

else if name is available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsByName('goButton');

v_obj.setAttribute('style','color:red;background:none');

Step 1: Goto https://projectlombok.org/download and click on 1.18.2

Step 2: Place your jar file in java installation path in my case it is C:\Program Files\Java\jdk-10.0.1\lib

step 3: Open your Eclipse IDE folder where you have in your PC.

Step 4: Add the place where I added then open your IDE it will open without any errors.
