$users = User::select('column1', 'column2', 'column3')->distinct()->get(); retrieves all three coulmns for distinct rows in the table. You can add as many columns as you wish.

So you could do something like this

Function Errorthingy(pParam)
On Error GoTo HandleErr

 ' your code here

    ExitHere:
    ' your finally code
    Exit Function

    HandleErr:
        Select Case Err.Number
        ' different error handling here'
        Case Else
            MsgBox "Error " & Err.Number & ": " & Err.Description, vbCritical, "ErrorThingy"
        End Select


   Resume ExitHere

End Function

If you want to bake in custom exceptions. (e.g. ones that violate business rules) use the example above but use the goto to alter the flow of the method as necessary.

By the time you say rate = lambda whatever... you've defeated the point of lambda and should just define a function. But, if you want a lambda, you can use 'and' and 'or'

lambda(T): (T>200) and (200*exp(-T)) or (400*exp(-T))

I use:

ps -ef | grep 786

Replace 786 with your PID or process name.

The key is to use background-color: inherit; on the pseudo element.
See: http://jsfiddle.net/EdUmc/

The format is %lu.

I think you are looking for the IGNORE_DUP_KEY option on your index. Have a look at IGNORE_DUP_KEY ON option documented at http://msdn.microsoft.com/en-us/library/ms186869.aspx which causes duplicate insertion attempts to produce a warning instead of an error.

void 0 returns undefined and can not be overwritten while undefined can be overwritten.

var undefined = "HAHA";

Starting Mongo 4.2, db.collection.update() can accept an aggregation pipeline, finally allowing the update of a field based on its own value:

// { a: "45", b: "x" }
// { a:  53,  b: "y" }
db.collection.update(
  { a : { $type: 1 } },
  [{ $set: { a: { $toString: "$a" } } }],
  { multi: true }
)
// { a: "45", b: "x" }
// { a: "53", b: "y" }

• The first part { a : { $type: 1 } } is the match query:

  • It filters which documents to update.
  • In this case, since we want to convert "a" to string when its value is a double, this matches elements for which "a" is of type 1 (double)).
  • This table provides the codes representing the different possible types.

• The second part [{ $set: { a: { $toString: "$a" } } }] is the update aggregation pipeline:

  • Note the squared brackets signifying that this update query uses an aggregation pipeline.
  • $set is a new aggregation operator (Mongo 4.2) which in this case modifies a field.
  • This can be simply read as "$set" the value of "a" to "$a" converted "$toString".
  • What's really new here, is being able in Mongo 4.2 to reference the document itself when updating it: the new value for "a" is based on the existing value of "$a".
  • Also note "$toString" which is a new aggregation operator introduced in Mongo 4.0.

• Don't forget { multi: true }, otherwise only the first matching document will be updated.

In case your cast isn't from double to string, you have the choice between different conversion operators introduced in Mongo 4.0 such as $toBool, $toInt, ...

And if there isn't a dedicated converter for your targeted type, you can replace { $toString: "$a" } with a $convert operation: { $convert: { input: "$a", to: 2 } } where the value for to can be found in this table:

db.collection.update(
  { a : { $type: 1 } },
  [{ $set: { a: { $convert: { input: "$a", to: 2 } } } }],
  { multi: true }
)

Original Answer:

If you are ready to opt for CSS3, you can use css3 translate property. Resize based on whatever is bigger. If your height is bigger and width is smaller than container, width will be stretch to 100% and height will be trimmed from both side. Same goes for larger width as well.

Your need, HTML:

<div class="img-wrap">
  <img src="http://lorempixel.com/300/160/nature/" />
</div>
<div class="img-wrap">
  <img src="http://lorempixel.com/300/200/nature/" />
</div>
<div class="img-wrap">
  <img src="http://lorempixel.com/200/300/nature/" />
</div>

And CSS:

.img-wrap {
  width: 200px;
  height: 150px;
  position: relative;
  display: inline-block;
  overflow: hidden;
  margin: 0;
}

div > img {
  display: block;
  position: absolute;
  top: 50%;
  left: 50%;
  min-height: 100%;
  min-width: 100%;
  transform: translate(-50%, -50%);
}

Voila! Working: http://jsfiddle.net/shekhardesigner/aYrhG/

Explanation

DIV is set to the relative position. This means all the child elements will get the starting coordinates (origins) from where this DIV starts.

The image is set as a BLOCK element, min-width/height both set to 100% means to resize the image no matter of its size to be the minimum of 100% of it's parent. min is the key. If by min-height, the image height exceeded the parent's height, no problem. It will look for if min-width and try to set the minimum height to be 100% of parents. Both goes vice-versa. This ensures there are no gaps around the div but image is always bit bigger and gets trimmed by overflow:hidden;

Now image, this is set to an absolute position with left:50% and top:50%. Means push the image 50% from the top and left making sure the origin is taken from DIV. Left/Top units are measured from the parent.

Magic moment:

transform: translate(-50%, -50%);

Now, this translate function of CSS3 transform property moves/repositions an element in question. This property deals with the applied element hence the values (x, y) OR (-50%, -50%) means to move the image negative left by 50% of image size and move to the negative top by 50% of image size.

Eg. if Image size was 200px × 150px, transform:translate(-50%, -50%) will calculated to translate(-100px, -75px). % unit helps when we have various size of image.

This is just a tricky way to figure out centroid of the image and the parent DIV and match them.

Apologies for taking too long to explain!

I know this is an old question, but with my quick read of the responses here, I didn't really see anyone mention that at times a synchronized method may be the wrong lock.
From Java Concurrency In Practice (pg. 72):

public class ListHelper<E> {
  public List<E> list = Collections.syncrhonizedList(new ArrayList<>());
...

public syncrhonized boolean putIfAbsent(E x) {
 boolean absent = !list.contains(x);
if(absent) {
 list.add(x);
}
return absent;
}

The above code has the appearance of being thread-safe. However, in reality it is not. In this case the lock is obtained on the instance of the class. However, it is possible for the list to be modified by another thread not using that method. The correct approach would be to use

public boolean putIfAbsent(E x) {
 synchronized(list) {
  boolean absent = !list.contains(x);
  if(absent) {
    list.add(x);
  }
  return absent;
}
}

The above code would block all threads trying to modify list from modifying the list until the synchronized block has completed.

This pattern has served me well. With this pattern, you create classes in separate files, load them into your overall app "as needed".

// Namespace
// (Creating new if not instantiated yet, otherwise, use existing and just add to it)
var myApp = myApp || {};

// "Package" 
// Similar to how you would establish a package in other languages
(function() {

// "Class"
var MyClass = function(params) {
    this.initialize(params);
}

    // "Private Static" vars 
    //    - Only accessible to functions in this class.
    //    - Doesn't get wiped out when we create a new instance.
    var countInstances = 0;
    var allInstances = [];

    // "Private Static" functions 
    //    - Same as above, but it's a function accessible 
    //      only to other functions in this class.
    function doSomething(){
    }

    // "Public Static" vars
    //    - Everyone has access.
    //    - Doesn't get wiped out when we create a new instance.
    MyClass.counter = 0;

    // "Public Static" functions
    //    - Same as above, but anyone can call this "static method".
    //    - Kinda like a singleton class situation.
    MyClass.foobar = function(){
    }

    // Public properties and methods are built into the "prototype"
    //    - This is how each instance can become unique unto itself.
    //    - Establishing "p" as "local" (Static Private) variable 
    //      simply so we don't have to keep typing "MyClass.prototype" 
    //      for each property and function.
var p = MyClass.prototype;

    // "Public" vars
    p.id = null;
    p.firstname = null;
    p.lastname = null;

    // "Private" vars
    //    - Only used by "this" instance.
    //    - There isn't "true" privacy for each 
    //      instance so we have to fake it. 
    //    - By tradition, we indicate "privacy"  
    //      by prefixing it with an underscore. 
    //    - So technically, anyone can access, but we simply 
    //      don't tell anyone about it (e.g. in your API)
    //      so no one knows about it :)
    p._foo = null;

    p.initialize = function(params){
        this.id = MyClass.counter++;
        this.firstname = params.firstname;
        this.lastname = params.lastname;
        MyClass.counter++;
        countInstances++;
        allInstances.push(this);
    }

    p.doAlert = function(theMessage){
        alert(this.firstname + " " + this.lastname + " said: " + theMessage + ". My id:" + this.id + ".  Total People:" + countInstances + ". First Person:" + allInstances[0].firstname + " " + allInstances[0].lastname);
    }


// Assign class to app
myApp.MyClass = MyClass;

// Close the "Package"
}());

// Usage example:
var bob = new myApp.MyClass({   firstname   :   "bob",
                                lastname    :   "er"
                            });

bob.doAlert("hello there");

You can change the format too by doing this

string fecha = DateTime.Now.ToString(format:"dd-MM-yyyy");

// this change the "/" for the "-"

c#: "\"", thus s.Replace("\"", "")

vb/vbs/vb.net: "" thus s.Replace("""", "")

It's easy to create this yourself

In your layout include the following ProgressBar with a specific drawable (note you should get the width from dimensions instead). The max value is important here:

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:max="500"
    android:progress="0"
    android:progressDrawable="@drawable/circular" />

Now create the drawable in your resources with the following shape. Play with the radius (you can use innerRadius instead of innerRadiusRatio) and thickness values.

circular (Pre Lollipop OR API Level < 21)

   <shape
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
   </shape>

circular ( >= Lollipop OR API Level >= 21)

    <shape
        android:useLevel="true"
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
     </shape>

useLevel is "false" by default in API Level 21 (Lollipop) .

Start Animation

Next in your code use an ObjectAnimator to animate the progress field of the ProgessBar of your layout.

ProgressBar progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", 0, 500); // see this max value coming back here, we animate towards that value
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();

Stop Animation

progressBar.clearAnimation();

P.S. unlike examples above, it give smooth animation.

Use the bash built-in variable SECONDS. Each time you reference the variable it will return the elapsed time since the script invocation.

Example:

echo "Start $SECONDS"
sleep 10
echo "Middle $SECONDS"
sleep 10
echo "End $SECONDS"

Output:

Start 0
Middle 10
End 20

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

I like Ibu's one but, I think I have a better solution using his idea.

//Fade In.
element.style.opacity = 0;
var Op1 = 0;
var Op2 = 1;
var foo1, foo2;
foo1 = setInterval(Timer1, 20);
function Timer1()
{
    element.style.opacity = Op1;
    Op1 = Op1 + .01;
    console.log(Op1); //Option, but I recommend it for testing purposes.
    if (Op1 > 1)
    {
        clearInterval(foo1);
        foo2 = setInterval(Timer3, 20);
    }
}

This solution uses a additional equation unlike Ibu's solution, which used a multiplicative equation. The way it works is it takes a time increment (t), an opacity increment (o), and a opacity limit (l) in the equation, which is: (T = time of fade in miliseconds) [T = (l/o)*t]. the "20" represents the time increments or intervals (t), the ".01" represents the opacity increments (o), and the 1 represents the opacity limit (l). When you plug the numbers in the equation you get 2000 milliseconds (or 2 seconds). Here is the console log:

Notice how the opacity follows the opacity increment amount of .01 just like in the code. If you use the code Ibu made,

//I made slight edits but keeped the ESSENTIAL stuff in it.
var op = 0.01;  // initial opacity
var timer = setInterval(function () {
    if (op >= 1){
        clearInterval(timer);
    }
    element.style.opacity = op;
    op += op * 0.1;
}, 20);

you will get these numbers (or something similar) in you console log. Here is what I got.

Notice that there is no discernible pattern. If you ran Ibu's code, you would never know how long the fade was. You would have to grab a timer and guess and check 2 seconds. Nonetheless, Ibu's code did make a pretty nice fade in (it probably works for fade out. I don't know because I didn't use a fade out yet). My code will also work for a fade out. Let's just say you wanted 2 seconds for a fade out. You can do that with my code. Here is how it would look:

//Fade out. (Continued from the fade in.
function Timer2()
{
    element.style.opacity = Op2;
    Op2 = Op2 - .01;
    console.log(Op2); //Option, but I recommend it for testing purposes.
    if (Op2 < 0)
    { 
        clearInterval(foo2);
    }
}

All I did was change the opacity to 1 (or fully opaque). I changed the opacity increment to -.01 so it would start turning invisible. Lastly, I changed the opacity limit to 0. When it hits the opacity limit, the timer will stop. Same as the last one, except it used 1 instead of 0. When you run the code, here is what the console log should relatively look like.

As you can see, the .01 pattern still exists in the fade out. Both fades are smooth and precise. I hope these codes helped you or gave you insight on the topic. If you have any additions or suggestions let me know. Thank you for taking the time to view this!

Doing the same in declarative pipeline syntax, below are few examples:

stage('master-branch-stuff') {
    when {
        branch 'master'
    }
    steps {
        echo 'run this stage - ony if the branch = master branch'
    }
}

stage('feature-branch-stuff') {
    when {
        branch 'feature/*'
    }
    steps {
        echo 'run this stage - only if the branch name started with feature/'
    }
}

stage('expression-branch') {
    when {
        expression {
            return env.BRANCH_NAME != 'master';
        }
    }
    steps {
        echo 'run this stage - when branch is not equal to master'
    }
}

stage('env-specific-stuff') {
    when { 
        environment name: 'NAME', value: 'this' 
    }
    steps {
        echo 'run this stage - only if the env name and value matches'
    }
}

UPDATE
New WHEN Clause
REF: https://jenkins.io/blog/2018/04/09/whats-in-declarative

equals - Compares two values - strings, variables, numbers, booleans - and returns true if they’re equal. I’m honestly not sure how we missed adding this earlier! You can do "not equals" comparisons using the not { equals ... } combination too.

changeRequest - In its simplest form, this will return true if this Pipeline is building a change request, such as a GitHub pull request. You can also do more detailed checks against the change request, allowing you to ask "is this a change request against the master branch?" and much more.

buildingTag - A simple condition that just checks if the Pipeline is running against a tag in SCM, rather than a branch or a specific commit reference.

tag - A more detailed equivalent of buildingTag, allowing you to check against the tag name itself.

you can use the UNION ALL keyword for this.

Here is the MSDN doc to do it in T-SQL http://msdn.microsoft.com/en-us/library/ms180026.aspx

UNION ALL - combines the result set

UNION- Does something like a Set Union and doesnt output duplicate values

For the difference with an example: http://sql-plsql.blogspot.in/2010/05/difference-between-union-union-all.html

Justin has correctly shown the expansion in the case where the join is just followed by a select. If you've got something else, it becomes more tricky due to transparent identifiers - the mechanism the C# compiler uses to propagate the scope of both halves of the join.

So to change Justin's example slightly:

var result = from sc in enumerableOfSomeClass
             join soc in enumerableOfSomeOtherClass
             on sc.Property1 equals soc.Property2
             where sc.X + sc.Y == 10
             select new { SomeClass = sc, SomeOtherClass = soc }

would be converted into something like this:

var result = enumerableOfSomeClass
    .Join(enumerableOfSomeOtherClass,
          sc => sc.Property1,
          soc => soc.Property2,
          (sc, soc) => new { sc, soc })
    .Where(z => z.sc.X + z.sc.Y == 10)
    .Select(z => new { SomeClass = z.sc, SomeOtherClass = z.soc });

The z here is the transparent identifier - but because it's transparent, you can't see it in the original query :)

@media queries serve this purpose. Here's an example:

@media only screen and (max-width: 991px) and (min-width: 769px){
 /* CSS that should be displayed if width is equal to or less than 991px and larger 
  than 768px goes here */
}

@media only screen and (max-width: 991px){
 /* CSS that should be displayed if width is equal to or less than 991px goes here */
}

You can use grep to get the byte-offset of the matching part of a string:

echo $str | grep -b -o str

As per your example:

[user@host ~]$ echo "The cat sat on the mat" | grep -b -o cat
4:cat

you can pipe that to awk if you just want the first part

echo $str | grep -b -o str | awk 'BEGIN {FS=":"}{print $1}'

Mozilla provides a simple framework for reading and writing cookies with full unicode support along with examples of how to use it.

Once included on the page, you can set a cookie:

docCookies.setItem(name, value);

read a cookie:

docCookies.getItem(name);

or delete a cookie:

docCookies.removeItem(name);

For example:

// sets a cookie called 'myCookie' with value 'Chocolate Chip'
docCookies.setItem('myCookie', 'Chocolate Chip');

// reads the value of a cookie called 'myCookie' and assigns to variable
var myCookie = docCookies.getItem('myCookie');

// removes the cookie called 'myCookie'
docCookies.removeItem('myCookie');

See more examples and details on Mozilla's document.cookie page.

A version of this simple js file is on github.

This is the code which can help u but dont forget to include message ui framewark and include delegates method MFMailComposeViewControllerDelegate

-(void)EmailButtonACtion{

        if ([MFMailComposeViewController canSendMail])
        {
            MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
            controller.mailComposeDelegate = self;
            [controller.navigationBar setBackgroundImage:[UIImage imageNamed:@"navigation_bg_iPhone.png"] forBarMetrics:UIBarMetricsDefault];
            controller.navigationBar.tintColor = [UIColor colorWithRed:51.0/255.0 green:51.0/255.0 blue:51.0/255.0 alpha:1.0];
            [controller setSubject:@""];
            [controller setMessageBody:@" " isHTML:YES];
            [controller setToRecipients:[NSArray arrayWithObjects:@"",nil]];

    }
    -(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
    {

        [MailAlert show];
        switch (result)

        }
        [self dismissViewControllerAnimated:YES completion:NULL];
        [MailAlert show];
    }

it depends on your php settings...
use phpinfo() and take a look at the session chapter. There are values like session.gc_maxlifetime and session.cache_expire and session.cookie_lifetime which affects the sessions lifetime

EDIT: it's like Martin write before

What you really want to do is to remove any string that starts with either http:// or https:// plus any combination of non white space characters. Here is how I would solve it. My solution is very similar to that of @tolgayilmaz

#Define the text from which you want to replace the url with "".
text ='''The link to this post is https://stackoverflow.com/questions/11331982/how-to-remove-any-url-within-a-string-in-python'''

import re
#Either use:
re.sub('http://\S+|https://\S+', '', text)
#OR 
re.sub('http[s]?://\S+', '', text)

And the result of running either code above is

>>> 'The link to this post is '

I prefer the second one because it is more readable.

Session is used mainly for storing user specific data [ session specific data ]. In the case of session you can use the value for the whole session until the session expires or the user abandons the session. Viewstate is the type of data that has scope only in the page in which it is used. You canot have viewstate values accesible to other pages unless you transfer those values to the desired page. Also in the case of viewstate all the server side control datas are transferred to the server as key value pair in __Viewstate and transferred back and rendered to the appropriate control in client when postback occurs.

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

Here is what worked for me:

• Open a command prompt
• Type telnet
• Microsoft Telnet>open <host name or IP address><space><port>

It will confirm whether the port is opened.

Additionally, how do I retrieve the number of days of a given month?

Aside from calculating it yourself (and consequently having to get leap years right), you can use a Date calculation to do it:

var y= 2010, m= 11;            // December 2010 - trap: months are 0-based in JS

var next= Date.UTC(y, m+1);    // timestamp of beginning of following month
var end= new Date(next-1);     // date for last second of this month
var lastday= end.getUTCDate(); // 31

In general for timestamp/date calculations I'd recommend using the UTC-based methods of Date, like getUTCSeconds instead of getSeconds(), and Date.UTC to get a timestamp from a UTC date, rather than new Date(y, m), so you don't have to worry about the possibility of weird time discontinuities where timezone rules change.

CREATE DEFINER=`root`@`localhost` FUNCTION `getNameInitials`(`fullname` VARCHAR(500), `separator` VARCHAR(1)) RETURNS varchar(70) CHARSET latin1
    DETERMINISTIC
BEGIN
DECLARE `result` VARCHAR(500) DEFAULT '';
DECLARE `position` TINYINT;



SET `fullname` = TRIM(`fullname`);

SET `position` = LOCATE(`separator`, `fullname`);

IF NOT `position`
THEN RETURN LEFT(`fullname`,1);
END IF;

SET `fullname` = CONCAT(`fullname`,`separator`);
SET `result` = LEFT(`fullname`, 1);

cycle: LOOP
    SET `fullname` = SUBSTR(`fullname`, `position` + 1);
    SET `position` = LOCATE(`separator`, `fullname`);

    IF NOT `position` OR NOT LENGTH(`fullname`)
    THEN LEAVE cycle;
    END IF;

    SET `result` = CONCAT(`result`,LEFT(`fullname`, 1));
   -- SET `result` = CONCAT_WS(`separator`, `result`, `buffer`);
END LOOP cycle;

RETURN upper(`result`);
END

1.Execute this function in mysql. 2.this will create a function. Now you can use this function anywhere you want.

 SELECT `getNameInitials`('Kaleem Ul Hassan', ' ') AS `NameInitials`;

3. The above getNameInitails first parameter is string you want to filter and second is the spectator character on which you want to separate you string. 4. In above example 'Kaleem Ul Hassan' is name and i want to get initials and my separator is space ' '.

If you don't mind adding a dependency, you can use JsonPath.

import com.jayway.jsonpath.JsonPath;

String firstName = JsonPath.read(rawJsonString, "$.detail.first_name");

"$" specifies the root of the raw json string and then you just specify the path to the field you want. This will always return a string. You'll have to do any casting yourself.

Be aware that it'll throw a PathNotFoundException at runtime if the path you specify doesn't exist.

Actually your command line arguments are practically like an array already. At least, you can treat the $@ variable much like an array. That said, you can convert it into an actual array like this:

myArray=( "$@" )

If you just want to type some arguments and feed them into the $@ value, use set:

$ set -- apple banana "kiwi fruit"
$ echo "$#"
3
$ echo "$@"
apple banana kiwi fruit

Understanding how to use the argument structure is particularly useful in POSIX sh, which has nothing else like an array.

Start thinking in terms of a: blast from the past

Once upon a time, long long ago, there lived in the land of computing interpreters and compilers. All kinds of fuss ensued over the merits of one over the other. The general opinion at that time was something along the lines of:

• Interpreter: Fast to develop (edit and run). Slow to execute because each statement had to be interpreted into machine code every time it was executed (think of what this meant for a loop executed thousands of times).
• Compiler: Slow to develop (edit, compile, link and run. The compile/link steps could take serious time). Fast to execute. The whole program was already in native machine code.

A one or two order of magnitude difference in the runtime performance existed between an interpreted program and a compiled program. Other distinguishing points, run-time mutability of the code for example, were also of some interest but the major distinction revolved around the run-time performance issues.

Today the landscape has evolved to such an extent that the compiled/interpreted distinction is pretty much irrelevant. Many compiled languages call upon run-time services that are not completely machine code based. Also, most interpreted languages are "compiled" into byte-code before execution. Byte-code interpreters can be very efficient and rival some compiler generated code from an execution speed point of view.

The classic difference is that compilers generated native machine code, interpreters read source code and generated machine code on the fly using some sort of run-time system. Today there are very few classic interpreters left - almost all of them compile into byte-code (or some other semi-compiled state) which then runs on a virtual "machine".

A space may only be encoded to "+" in the "application/x-www-form-urlencoded" content-type key-value pairs query part of an URL. In my opinion, this is a MAY, not a MUST. In the rest of URLs, it is encoded as %20.

In my opinion, it's better to always encode spaces as %20, not as "+", even in the query part of an URL, because it is the HTML specification (RFC-1866) that specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs (see paragraph 8.2.1. subparagraph 1.)

This way of encoding form data is also given in later HTML specifications. For example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.

Here is a sample string in URL where the HTML specification allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses. In other cases, spaces should be encoded to %20. But since it's hard to correctly determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

The implementation depends on the programming language that you chose.

If your URL contains national characters, first encode them to UTF-8 and then percent-encode the result.

dex2jar helps to decompile your apk but not 100%. You will have some problems with .smali files. Dex2jar cannot convert it to java. I know one application that can decompile your apk source files and no problems with .smali files. Here is a link http://www.hensence.com/en/smali2java/

See RFC2616:

401 Unauthorized:

If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials.

403 Forbidden:

The server understood the request, but is refusing to fulfill it.

Update

From your use case, it appears that the user is not authenticated. I would return 401.

Edit: RFC2616 is obsolete, see RFC7231 and RFC7235.

From marshmallow version, developers need to ask for runtime permissions to user. Let me give you whole process for asking runtime permissions.

I am using reference from here : marshmallow runtime permissions android.

First create a method which checks whether all permissions are given or not

private  boolean checkAndRequestPermissions() {
        int camerapermission = ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA);
        int writepermission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        int permissionLocation = ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION);
        int permissionRecordAudio = ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO);


        List<String> listPermissionsNeeded = new ArrayList<>();

        if (camerapermission != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.CAMERA);
        }
        if (writepermission != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        }
        if (permissionLocation != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
        }
        if (permissionRecordAudio != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.RECORD_AUDIO);
        }
        if (!listPermissionsNeeded.isEmpty()) {
            ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
            return false;
        }
        return true;
    } 

Now here is the code which is run after above method. We will override onRequestPermissionsResult() method :

 @Override
    public void onRequestPermissionsResult(int requestCode,
                                           String permissions[], int[] grantResults) {
        Log.d(TAG, "Permission callback called-------");
        switch (requestCode) {
            case REQUEST_ID_MULTIPLE_PERMISSIONS: {

                Map<String, Integer> perms = new HashMap<>();
                // Initialize the map with both permissions
                perms.put(Manifest.permission.CAMERA, PackageManager.PERMISSION_GRANTED);
                perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
                perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
                perms.put(Manifest.permission.RECORD_AUDIO, PackageManager.PERMISSION_GRANTED);
                // Fill with actual results from user
                if (grantResults.length > 0) {
                    for (int i = 0; i < permissions.length; i++)
                        perms.put(permissions[i], grantResults[i]);
                    // Check for both permissions
                    if (perms.get(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED
                            && perms.get(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED 
&& perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED 
&& perms.get(Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "sms & location services permission granted");
                        // process the normal flow
                        Intent i = new Intent(MainActivity.this, WelcomeActivity.class);
                        startActivity(i);
                        finish();
                        //else any one or both the permissions are not granted
                    } else {
                        Log.d(TAG, "Some permissions are not granted ask again ");
                        //permission is denied (this is the first time, when "never ask again" is not checked) so ask again explaining the usage of permission
//                        // shouldShowRequestPermissionRationale will return true
                        //show the dialog or snackbar saying its necessary and try again otherwise proceed with setup.
                        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA) 
|| ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) 
|| ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)
 || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.RECORD_AUDIO)) {
                            showDialogOK("Service Permissions are required for this app",
                                    new DialogInterface.OnClickListener() {
                                        @Override
                                        public void onClick(DialogInterface dialog, int which) {
                                            switch (which) {
                                                case DialogInterface.BUTTON_POSITIVE:
                                                    checkAndRequestPermissions();
                                                    break;
                                                case DialogInterface.BUTTON_NEGATIVE:
                                                    // proceed with logic by disabling the related features or quit the app.
                                                    finish();
                                                    break;
                                            }
                                        }
                                    });
                        }
                        //permission is denied (and never ask again is  checked)
                        //shouldShowRequestPermissionRationale will return false
                        else {
                            explain("You need to give some mandatory permissions to continue. Do you want to go to app settings?");
                            //                            //proceed with logic by disabling the related features or quit the app.
                        }
                    }
                }
            }
        }

    }

If user clicks on Deny option then showDialogOK() method will be used to show dialog

If user clicks on Deny and also clicks a checkbox saying "never ask again", then explain() method will be used to show dialog.

methods to show dialogs :

 private void showDialogOK(String message, DialogInterface.OnClickListener okListener) {
        new AlertDialog.Builder(this)
                .setMessage(message)
                .setPositiveButton("OK", okListener)
                .setNegativeButton("Cancel", okListener)
                .create()
                .show();
    }
    private void explain(String msg){
        final android.support.v7.app.AlertDialog.Builder dialog = new android.support.v7.app.AlertDialog.Builder(this);
        dialog.setMessage(msg)
                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                        //  permissionsclass.requestPermission(type,code);
                        startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:com.exampledemo.parsaniahardik.marshmallowpermission")));
                    }
                })
                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                        finish();
                    }
                });
        dialog.show();
    }

Above code snippet asks for four permissions at a time. You can also ask for any number of permissions in your any activity as per your requirements.

For this you can use text-overflow: ellipsis; property. Write like this

span {_x000D_
    display: inline-block;_x000D_
    width: 180px;_x000D_
    white-space: nowrap;_x000D_
    overflow: hidden !important;_x000D_
    text-overflow: ellipsis;_x000D_
}

<span>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book</span>

If you don't mind importing the json module, then the best way to handle it is through json.JSONDecodeError (or json.decoder.JSONDecodeError as they are the same) as using default errors like ValueError could catch also other exceptions not necessarily connected to the json decode one.

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want

//EDIT (Oct 2020):

As @Jacob Lee noted in the comment, there could be the basic common TypeError raised when the JSON object is not a str, bytes, or bytearray. Your question is about JSONDecodeError, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want
except TypeError as e:
    # do whatever you want in this case

I am using Google API for .Net, but no doubt you can find the same way to obtain this information using other version of API. As user872858 mentioned, scope userinfo.profile has been deprecated (google article) .

To obtain user profile info I use following code (re-written part from google's example):

IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(
                                  new GoogleAuthorizationCodeFlow.Initializer
                                      {
                                            ClientSecrets = Secrets,
                                            Scopes = new[] { PlusService.Scope.PlusLogin,"https://www.googleapis.com/auth/plus.profile.emails.read"  }
                                       });    
TokenResponse _token = flow.ExchangeCodeForTokenAsync("", code, "postmessage", 
                              CancellationToken.None).Result;

                    // Create an authorization state from the returned token.
                    context.Session["authState"] = _token;

                    // Get tokeninfo for the access token if you want to verify.
                    Oauth2Service service = new Oauth2Service(
                     new Google.Apis.Services.BaseClientService.Initializer());
                    Oauth2Service.TokeninfoRequest request = service.Tokeninfo();
                    request.AccessToken = _token.AccessToken;
                    Tokeninfo info = request.Execute();
                    if (info.VerifiedEmail.HasValue && info.VerifiedEmail.Value)
                    {
                        flow = new GoogleAuthorizationCodeFlow(
                                    new GoogleAuthorizationCodeFlow.Initializer
                                         {
                                             ClientSecrets = Secrets,
                                             Scopes = new[] { PlusService.Scope.PlusLogin }
                                          });

                        UserCredential credential = new UserCredential(flow, 
                                                              "me", _token);
                        _token = credential.Token;
                        _ps = new PlusService(
                              new Google.Apis.Services.BaseClientService.Initializer()
                               {
                                   ApplicationName = "Your app name",
                                   HttpClientInitializer = credential
                               });
                        Person userProfile = _ps.People.Get("me").Execute();
                    }

Than, you can access almost anything using userProfile.

UPDATE: To get this code working you have to use appropriate scopes on google sign in button. For example my button:

     <button class="g-signin"
             data-scope="https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.profile.emails.read"
             data-clientid="646361778467-nb2uipj05c4adlk0vo66k96bv8inqles.apps.googleusercontent.com"
             data-accesstype="offline"
             data-redirecturi="postmessage"
             data-theme="dark"
             data-callback="onSignInCallback"
             data-cookiepolicy="single_host_origin"
             data-width="iconOnly">
     </button>

Try this:

import matplotlib as plt

after importing the file we can use matplotlib library but remember to use it as plt

df.plt(kind='line',figsize=(10,5))

after that the plot will be done and size increased. In figsize the 10 is for breadth and 5 is for height. Also other attributes can be added to the plot too.

I'm going to add to the answer given before.

It's not a bug in your code or the browser's code. It's the JavaScript code inside the YouTube iframe polls for the extensions it could interoperate with in case they were installed (likely to determine if the extension is installed).

Look at the source of www-embed-player.js (loaded from s.ytimg.com, it's YouTube static files CDN). You'll find the following:

function Wj(a){return"chrome-extension://"+a+"/cast_sender.js"}

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.

src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?

Blob URLs can only be generated internally by the browser. URL.createObjectURL() will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL(). These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).

What is blob url?
Why it is used?

Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.

For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.

It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.

Can i make my own blob url on a server?

No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.

if you have then Additional detail

You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL() to generate a local URL for it:

var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
    url = URL.createObjectURL(blob),
    img = new Image();

img.onload = function() {
    URL.revokeObjectURL(this.src);     // clean-up memory
    document.body.appendChild(this);   // add image to DOM
}

img.src = url;                         // can now "stream" the bytes

Note that URL may be prefixed in webkit-browsers, so use:

var url = (URL || webkitURL).createObjectURL(...);

You can use:

$answer.replace(' ' , '')

or

$answer -replace " ", ""

if you want to remove all whitespace you can use:

$answer -replace "\s", ""

I guess this can help :

selection styles

It's possible to define color and background for text the user selects.

Try it below. If you select something and it looks like this, your browser supports selection styles.

This is the paragraph with normal ::selection.

This is the paragraph with ::-moz-selection.

This is the paragraph with ::-webkit-selection.

Testsheet:

p.normal::selection {
  background:#cc0000;
  color:#fff;
}

p.moz::-moz-selection {
  background:#cc0000;
  color:#fff;
}

p.webkit::-webkit-selection {
  background:#cc0000;
  color:#fff;
}

Quoted from Quirksmode

Joining lines with svgs was worth a shot for me, and it worked perfectly... first of all, Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. SVG images and their behaviors are defined in XML text files. you can create an svg in HTML using <svg> tag. Adobe Illustrator is one of the best software used to create an complex svgs using paths.

Procedure to join two divs using a line :

1. create two divs and give them any position as you need

   <div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#e53935 ; position:absolute;"></div>
   <div id="div2" style="width: 100px; height: 100px; top:0; left:300px; background:#4527a0 ; position:absolute;"></div>
   

   (for the sake of explanation I am doing some inline styling but it is always good to make a separate css file for styling)

2. <svg><line id="line1"/></svg>

   Line tag allows us to draw a line between two specified points(x1,y1) and (x2,y2). (for a reference visit w3schools.) we haven't specified them yet. because we will be using jQuery to edit the attributes (x1,y1,x2,y2) of line tag.

3. in <script> tag write

   line1 = $('#line1');   
   div1 = $('#div1');   
   div2 = $('#div2');
   

   I used selectors to select the two divs and line...

   var pos1 = div1.position();
   var pos2 = div2.position();
   

   jQuery position() method allows us to obtain the current position of an element. For more information, visit https://api.jquery.com/position/ (you can use offset() method too)

Now as we have obtained all the positions we need we can draw line as follows...

line1
  .attr('x1', pos1.left)
  .attr('y1', pos1.top)
  .attr('x2', pos2.left)
  .attr('y2', pos2.top);

jQuery .attr() method is used to change attributes of the selected element.

All we did in above line is we changed attributes of line from

x1 = 0
y1 = 0
x2 = 0
y2 = 0

to

x1 = pos1.left
y1 = pos1.top
x2 = pos2.left
y2 = pos2.top

as position() returns two values, one 'left' and other 'top', we can easily access them using .top and .left using the objects (here pos1 and pos2) ...

Now line tag has two distinct co-ordinates to draw line between two points.

Tip: add event listeners as you need to divs

Tip: make sure you import jQuery library first before writing anything in script tag

After adding co-ordinates through JQuery ... It will look something like this

Following snippet is for demonstration purpose only, please follow steps above to get correct solution

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#e53935 ; position:absolute;"></div>_x000D_
<div id="div2" style="width: 100px; height: 100px; top:0; left:300px; background:#4527a0 ; position:absolute;"></div>_x000D_
<svg width="500" height="500"><line x1="50" y1="50" x2="350" y2="50" stroke="red"/></svg>

I don't think there is anything you can do to avoid what you are already doing, however, if you are building the table on the client with javascript, you can always add the style rules dynamically, so you can allow for any number of columns without cluttering up your css file with all those rules. See http://www.hunlock.com/blogs/Totally_Pwn_CSS_with_Javascript if you don't know how to do this.

Edit: For your "sticky" toggle, you should just append class names rather than replacing them. For instance, you can give it a class name of "hide2 hide3" etc. I don't think you really need the "show" classes, since that would be the default. Libraries like jQuery make this easy, but in the absence, a function like this might help:

var modifyClassName = function (elem, add, string) {
var s = (elem.className) ? elem.className : "";
var a = s.split(" ");
if (add) {
  for (var i=0; i<a.length; i++) {
      if (a[i] == string) {
          return;
          }
      }
  s += " " + string;
  }
else {
    s = "";
    for (var i=0; i<a.length; i++) {
        if (a[i] != string)
            s += a[i] + " "; 
        }
    }
elem.className = s;
}

With newer versions of client tools, there are multiple options to format the query output. The rest is to spool it to a file or save the output as a file depending on the client tool. Here are few of the ways:

• SQL*Plus

Using the SQL*Plus commands you could format to get your desired output. Use SPOOL to spool the output to a file.

For example,

SQL> SET colsep ,
SQL> SET pagesize 20
SQL> SET trimspool ON
SQL> SET linesize 200
SQL> SELECT * FROM scott.emp;

• SQL Developer Version pre 4.1

Alternatively, you could use the new /*csv*/ hint in SQL Developer.

/*csv*/

For example, in my SQL Developer Version 3.2.20.10:

Now you could save the output into a file.

• SQL Developer Version 4.1

New in SQL Developer version 4.1, use the following just like sqlplus command and run as script. No need of the hint in the query.

SET SQLFORMAT csv

Now you could save the output into a file.

In my case, Windows had ran an update and was waiting to restart the PC. I hadn't seen any notifications but, well... turning it off and turning it on again fixed the problem.

Try that first before monkeying with any of these Visual Studio directories and applications.

Well if you are new to C# with cmd-line exp. you can use online sites like "https://curl.olsh.me/" or search curl to C# converter will returns site that could do that for you.

or if you are using postman you can use Generate Code Snippet only problem with Postman code generator is the dependency on RestSharp library.

List constructor accepts any data structure that implements Collection interface to be used to build a list.

To get all the keys from a hash map to a list:

Map<String, Integer> map = new HashMap<String, Integer>();
List<String> keys = new ArrayList<>(map.keySet());

To get all the values from a hash map to a list:

Map<String, Integer> map = new HashMap<String, Integer>();
List<Integer> values = new ArrayList<>(map.values());

Step 1
public class TopAttractions extends Fragment implements OnMapReadyCallback, 
GoogleMap.OnMarkerClickListener

Step 2
gMap.setOnMarkerClickListener(this);

Step 3
@Override
public boolean onMarkerClick(Marker marker) {

Set the activity content from a layout resource. The resource will be inflated, adding all top-level views to the activity.

• Activity is basically a empty window
• SetContentView is used to fill the window with the UI provided from layout file incase of setContentView(R.layout.somae_file).
• Here layoutfile is inflated to view and added to the Activity context(Window).

You just need to set the related drawables and set them in the checkbox:

<CheckBox 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:text="new checkbox" 
    android:background="@drawable/my_checkbox_background"
    android:button="@drawable/my_checkbox" />

The trick is on how to set the drawables. Here's a good tutorial about this.

This is an old post, but I ended up using Peter Lang's thoughts, and did a similar, but yet different approach. Here is what I did:

CREATE OR REPLACE FUNCTION multi_replace(
                        pString IN VARCHAR2
                        ,pReplacePattern IN VARCHAR2
) RETURN VARCHAR2 IS
    iCount  INTEGER;
    vResult VARCHAR2(1000);
    vRule   VARCHAR2(100);
    vOldStr VARCHAR2(50);
    vNewStr VARCHAR2(50);
BEGIN
    iCount := 0;
    vResult := pString;
    LOOP
        iCount := iCount + 1;

        -- Step # 1: Pick out the replacement rules
        vRule := REGEXP_SUBSTR(pReplacePattern, '[^/]+', 1, iCount);

        -- Step # 2: Pick out the old and new string from the rule
        vOldStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 1);
        vNewStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 2);

        -- Step # 3: Do the replacement
        vResult := REPLACE(vResult, vOldStr, vNewStr);

        EXIT WHEN vRule IS NULL;
    END LOOP;

    RETURN vResult;
END multi_replace;

Then I can use it like this:

SELECT  multi_replace(
                        'This is a test string with a #, a $ character, and finally a & character'
                        ,'#=%23/$=%24/&=%25'
        )
FROM dual

This makes it so that I can can any character/string with any character/string.

I wrote a post about this on my blog.

Another important fact is that reject() DOES NOT terminate control flow like a return statement does. In contrast throw does terminate control flow.

Example:

new Promise((resolve, reject) => {_x000D_
  throw "err";_x000D_
  console.log("NEVER REACHED");_x000D_
})_x000D_
.then(() => console.log("RESOLVED"))_x000D_
.catch(() => console.log("REJECTED"));

vs

new Promise((resolve, reject) => {_x000D_
  reject(); // resolve() behaves similarly_x000D_
  console.log("ALWAYS REACHED"); // "REJECTED" will print AFTER this_x000D_
})_x000D_
.then(() => console.log("RESOLVED"))_x000D_
.catch(() => console.log("REJECTED"));

A colleague found this MS auto-uninstall tool which has successfully uninstalled VS2008 for me and saved me hours of work!!

Hopefully this might be useful to others. Doesn't speak highly of MS's faith in their usual VS maintenance tools that they have to provide this as well!

You can use

[5,10].min 

or

[4,7].max

It's a method for Arrays.

I usually accomplish this using the :after pseudo-element:

of course it depends on usage, this method allows control over individual borders, rather than using the hard shadow method.

you could also set -1px offsets and use a background linear gradient (no border) for a different effect once again.

body {_x000D_
  margin: 20px;_x000D_
}_x000D_
_x000D_
a {_x000D_
  background: #999;_x000D_
  padding: 10px 20px;_x000D_
  border-radius: 5px;_x000D_
  text-decoration: none;_x000D_
  color: #fff;_x000D_
  position: relative;_x000D_
  border: 2px solid #000;_x000D_
}_x000D_
_x000D_
a:after {_x000D_
  content: '';_x000D_
  display: block;_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  bottom: 0;_x000D_
  left: 0;_x000D_
  right: 0;_x000D_
  border-radius: 5px;_x000D_
  border: 2px solid #ccc;_x000D_
}

Since Windows doesn't have a grep command, this worked for me in PowerShell:

git log --find-renames --diff-filter=D --summary | Select-String -Pattern "delete mode" | sort -u > deletions.txt

It is a pointer to a pointer, so yes, in a way it's a 2D character array. In the same way that a char* could indicate an array of chars, a char** could indicate that it points to and array of char*s.

If we are using TypeScript, we can update the type definition file by running the command npm install @types/node from the terminal or command prompt.

In addition to the above answer, this is the actual code:

[[UIDevice currentDevice] name];

I'd think a better way is to use RadioGroup and set the listener on this to change and update the View accordingly (saves you having 2 or 3 or 4 etc listeners).

    RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
    radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
    {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // checkedId is the RadioButton selected
        }
    });

You might want to have a look at this specification for CSV. Bear in mind that there is no official recognized specification.

If you do not now the delimiter it will not be possible to do this so you have to find out somehow. If you can do a manual inspection of the file you should quickly be able to see what it is and hard code it in your program. If the delimiter can vary your only hope is to be able to deduce if from the formatting of the known data. When Excel imports CSV files it lets the user choose the delimiter and this is a solution you could use as well.

Just for completeness (because nobody else posted the most obvious answer):

Oracle:

DECODE(PC_SL_LDGR_CODE, '02', 'DR', 'CR')

MSSQL (2012+):

IIF(PC_SL_LDGR_CODE='02', 'DR', 'CR')

The bad news:

DECODE with more than 4 arguments would result in an ugly IIF cascade

Most of the solutions are directly using grep command to find the class. However, it would not give you the package name of the class. Also if the jar is compressed, grep will not work.

This solution is using jar command to list the contents of the file and grep the class you are looking for.

It will print out the class with package name and also the jar file name.

find . -type f -name '*.jar' -print0 |  xargs -0 -I '{}' sh -c 'jar tf {} | grep Hello.class &&  echo {}'

You can also search with your package name like below:

find . -type f -name '*.jar' -print0 |  xargs -0 -I '{}' sh -c 'jar tf {} | grep com/mypackage/Hello.class &&  echo {}'

This issue sometimes occurs when you have a control registered as an AsyncPostbackTrigger in multiple update panels.

If that's not the problem, try adding the following right after the script manager declaration, which I found in this post by manowar83, which copies and slightly modifies this post by larryw:

<script type="text/javascript" language="javascript">
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
    function EndRequestHandler(sender, args){
        if (args.get_error() != undefined){
            args.set_errorHandled(true);
        }
    }
</script>

There are a few more solutions discussed here: http://forums.asp.net/t/1066976.aspx/9/10

in my case it happens when I try add types to Promise.all handler:

Promise.all([1,2]).then(([num1, num2]: [number, number])=> console.log('res', num1));

If remove : [number, number], the error is gone.

For those who are still trying, this link helped me out, too; it just puts it all together:

http://dotnetslackers.com/VB_NET/re-36138_How_To_Get_Selected_Date_from_MonthCalendar_control.aspx

private void MonthCalendar1_DateChanged(object sender, System.Windows.Forms.DateRangeEventArgs e)
{
//Display the dates for selected range
Label1.Text = "Dates Selected from :" + (MonthCalendar1.SelectionRange.Start() + " to " + MonthCalendar1.SelectionRange.End);

//To display single selected of date
//MonthCalendar1.MaxSelectionCount = 1;

//To display single selected of date use MonthCalendar1.SelectionRange.Start/ MonthCalendarSelectionRange.End
Label2.Text = "Date Selected :" + MonthCalendar1.SelectionRange.Start;
}

Apply (different) name attribute to both buttons like

<button name="one">

and catch them in request.data.

for me this is what worked...

I edited the ./bash_profile and added below command

export PATH="/usr/local/opt/openssl/bin:$PATH"

Auto-alignment? Lawful good?

If you mean formatting, then Ctrl+Shift+F.

A great resource is iosfonts.com, which says that the name for that font is HelveticaNeue-UltraLight. So you'd use this code:

label.font = UIFont(name: "HelveticaNeue-UltraLight", size: 30)

If the system can't find the font, it defaults to a 'normal' font - I think it's something like 11-point Helvetica. This can be quite confusing, always check your font names.

I did a bit of searching and found that if one is being pedantic then yes it might be considered useless...in particular situations...it depends on how time sensitive your requirements are...

Check out this quote from the Java Sun site:

The real-time clock and System.nanoTime() are both based on the same system call and thus the same clock.

With Java RTS, all time-based APIs (for example, Timers, Periodic Threads, Deadline Monitoring, and so forth) are based on the high-resolution timer. And, together with real-time priorities, they can ensure that the appropriate code will be executed at the right time for real-time constraints. In contrast, ordinary Java SE APIs offer just a few methods capable of handling high-resolution times, with no guarantee of execution at a given time. Using System.nanoTime() between various points in the code to perform elapsed time measurements should always be accurate.

Java also has a caveat for the nanoTime() method:

This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time. The value returned represents nanoseconds since some fixed but arbitrary time (perhaps in the future, so values may be negative). This method provides nanosecond precision, but not necessarily nanosecond accuracy. No guarantees are made about how frequently values change. Differences in successive calls that span greater than approximately 292.3 years (2⁶³ nanoseconds) will not accurately compute elapsed time due to numerical overflow.

It would seem that the only conclusion that can be drawn is that nanoTime() cannot be relied upon as an accurate value. As such, if you do not need to measure times that are mere nano seconds apart then this method is good enough even if the resulting returned value is negative. However, if you're needing higher precision, they appear to recommend that you use JAVA RTS.

So to answer your question...no nanoTime() is not useless....its just not the most prudent method to use in every situation.

As said in previous answers the 'normal' way is to add it to a JScrollPane, but sometimes you don't want it to scroll (don't ask me when:)). Then you can add the TableHeader yourself. Like this:

JPanel tablePanel = new JPanel(new BorderLayout());
JTable table = new JTable();
tablePanel.add(table, BorderLayout.CENTER);
tablePanel.add(table.getTableHeader(), BorderLayout.NORTH);

If you want to (easily) change the author for the current branch I would use something like this:

# update author for everything since origin/master
git rebase \
  -i origin/master \
  --exec 'git commit --amend --no-edit --author="Author Name <[email protected]>"'

I had something like this, my suggestion would be to use java for things like this, don't put in boilerplate code

For the substition impaired here is a real example from GitHub.com to a local directory:

svn ls https://github.com/rdcarp/playing-cards/trunk/PumpkinSoup.PlayingCards.Interfaces
svn export https://github.com/rdcarp/playing-cards/trunk/PumpkinSoup.PlayingCards.Interfaces /temp/SvnExport/Washburn

See: Download a single folder or directory from a GitHub repo for more details.

Doing it as a stored procedure does have lot of advantages. You can get the sequence that is inserted into the table using syntax insert into table_name values returning.

Like:

declare
some_seq_val  number;
lv_seq        number;
begin
some_seq_val := your_seq.nextval;
insert into your_tab (col1, col2, col3) 
values (some_seq_val, val2, val3) returning some_seq_val into lv_seq;

dbms_output.put_line('The inserted sequence is: '||to_char(lv_seq));
end;
/

Or just return some_seq_val. In case you are not making use of SEQUENCE, and arriving the sequence on some calculation, you can make use of returning into effectively.

(Latest as of 2020) For version Chrome Version 83.0.4103.61 :

1. Select the element you want to inspect

2. Choose the Event Listeners tab

3. Make sure to check the Framework listeners to show the real javascript file instead of the jquery function.

To check if file is empty or has only white spaces, you can use grep:

if [[ -z $(grep '[^[:space:]]' $filename) ]] ; then
  echo "Empty file" 
  ...

You can always use Robomongo. As of v0.8.3 there is a tool that can do this by right-clicking on the collection and selecting "Copy Collection to Database"

For details, see http://blog.robomongo.org/whats-new-in-robomongo-0-8-3/

This feature was removed in 0.8.5 due to its buggy nature so you will have to use 0.8.3 or 0.8.4 if you want to try it out.

The best way to use selenium.webdriver.support.ui.Select class to work to with dropdown selection but some time it does not work as expected due to designing issue or other issues of the HTML.

In this type of situation you can also prefer as alternate solution using execute_script() as below :-

option_visible_text = "Banana"
select = driver.find_element_by_id("fruits01")

#now use this to select option from dropdown by visible text 
driver.execute_script("var select = arguments[0]; for(var i = 0; i < select.options.length; i++){ if(select.options[i].text == arguments[1]){ select.options[i].selected = true; } }", select, option_visible_text);

You can do this easily in vanilla JS:

Using find

const savedViews = [{"description":"object1","id":1},{"description":"object2","id":2},{"description":"object3","id":3},{"description":"object4","id":4}];_x000D_
_x000D_
const view = 'object2';_x000D_
_x000D_
const delete_id = savedViews.find(obj => {_x000D_
  return obj.description === view;_x000D_
}).id;_x000D_
_x000D_
console.log(delete_id);

Using filter (original answer)

const savedViews = [{"description":"object1","id":1},{"description":"object2","id":2},{"description":"object3","id":3},{"description":"object4","id":4}];_x000D_
_x000D_
const view = 'object2';_x000D_
_x000D_
const delete_id = savedViews.filter(function (el) {_x000D_
  return el.description === view;_x000D_
})[0].id;_x000D_
_x000D_
console.log(delete_id);

In my legacy app Array.from of prototype js was conflicting with angular's Array.from that was causing this problem. I resolved it by saving angular's Array.from version and reassigning it after prototype load.

The error message is giving you most of what you need. This isn't just about the TrustedHosts list; it's saying that in order to use an IP address with the default authentication scheme, you have to ALSO be using HTTPS (which isn't configured by default) and provide explicit credentials. I can tell you're at least not using SSL, because you didn't use the -UseSSL switch.

Note that SSL/HTTPS is not configured by default - that's an extra step you'll have to take. You can't just add -UseSSL.

The default authentication mechanism is Kerberos, and it wants to see real host names as they appear in AD. Not IP addresses, not DNS CNAME nicknames. Some folks will enable Basic authentication, which is less picky - but you should also set up HTTPS since you'd otherwise pass credentials in cleartext. Enable-PSRemoting only sets up HTTP.

Adding names to your hosts file won't work. This isn't an issue of name resolution; it's about how the mutual authentication between computers is carried out.

Additionally, if the two computers involved in this connection aren't in the same AD domain, the default authentication mechanism won't work. Read "help about_remote_troubleshooting" for information on configuring non-domain and cross-domain authentication.

From the docs at http://technet.microsoft.com/en-us/library/dd347642.aspx

HOW TO USE AN IP ADDRESS IN A REMOTE COMMAND
-----------------------------------------------------
    ERROR:  The WinRM client cannot process the request. If the
    authentication scheme is different from Kerberos, or if the client
    computer is not joined to a domain, then HTTPS transport must be used
    or the destination machine must be added to the TrustedHosts
    configuration setting.

The ComputerName parameters of the New-PSSession, Enter-PSSession and
Invoke-Command cmdlets accept an IP address as a valid value. However,
because Kerberos authentication does not support IP addresses, NTLM
authentication is used by default whenever you specify an IP address. 

When using NTLM authentication, the following procedure is required
for remoting.

1. Configure the computer for HTTPS transport or add the IP addresses
   of the remote computers to the TrustedHosts list on the local
   computer.

   For instructions, see "How to Add a Computer to the TrustedHosts
   List" below.


2. Use the Credential parameter in all remote commands.

   This is required even when you are submitting the credentials

Basically this world's problems can be categorized as

         1) Unsolvable Problem          2) Intractable Problem          3) NP-Problem          4) P-Problem

         1)The first one is no solution to the problem.          2)The second is the need exponential time (that is O (2 ^ n) above).          3)The third is called the NP.          4)The fourth is easy problem.

P: refers to a solution of the problem of Polynomial Time.

NP: refers Polynomial Time yet to find a solution. We are not sure there is no Polynomial Time solution, but once you provide a solution, this solution can be verified in Polynomial Time.

NP Complete: refers in Polynomial Time we still yet to find a solution, but it can be verified in Polynomial Time . The problem NPC in NP is the more difficult problem, so if we can prove that we have P solution to NPC problem then NP problems that can be found in P solution.

NP Hard: refers Polynomial Time is yet to find a solution, but it sure is not able to be verified in Polynomial Time . NP Hard problem surpasses NPC difficulty.

During unzip in a cygwin directory on Win7, .exe and .dll need to be given executable mode. This is the solution from a mintty (or other $TERM) terminal run with cygwin on windows 7:

me@mymachine ~/eclipse
$ find . -name "*.dll" -exec chmod +x {} \;

tried with Juno (eclipse 4.2) freshly unzipped, cygwin 1.7.something

You could also use Artifactory Query Language to get the latest artifact.

The following shell script is just an example. It uses 'items.find()' (which is available in the non-Pro version), e.g. items.find({ "repo": {"$eq":"my-repo"}, "name": {"$match" : "my-file*"}}) that searches for files that have a repository name equal to "my-repo" and match all files that start with "my-file". Then it uses the shell JSON parser ./jq to extract the latest file by sorting by the date field 'updated'. Finally it uses wget to download the artifact.

#!/bin/bash

# Artifactory settings
host="127.0.0.1"
username="downloader"
password="my-artifactory-token"

# Use Artifactory Query Language to get the latest scraper script (https://www.jfrog.com/confluence/display/RTF/Artifactory+Query+Language)
resultAsJson=$(curl -u$username:"$password" -X POST  http://$host/artifactory/api/search/aql -H "content-type: text/plain" -d 'items.find({ "repo": {"$eq":"my-repo"}, "name": {"$match" : "my-file*"}})')

# Use ./jq to pars JSON
latestFile=$(echo $resultAsJson | jq -r '.results | sort_by(.updated) [-1].name')

# Download the latest scraper script
wget -N -P ./libs/ --user $username --password $password http://$host/artifactory/my-repo/$latestFile

You can use the following to clear all the elements.

var select = document.getElementById("DropList");
var length = select.options.length;
for (i = length-1; i >= 0; i--) {
  select.options[i] = null;
}

I hope you were joking about writing your own parser. :-)

For such a simple mapping, most tools from http://json.org (section java) would work. For one of them (Jackson https://github.com/FasterXML/jackson-databind/#5-minute-tutorial-streaming-parser-generator), you'd do:

Map<String,Object> result =
        new ObjectMapper().readValue(JSON_SOURCE, HashMap.class);

(where JSON_SOURCE is a File, input stream, reader, or json content String)

As the documentation states ^[docs],

In user defined base classes, abstract methods should raise this exception when they require derived classes to override the method, or while the class is being developed to indicate that the real implementation still needs to be added.

Note that although the main stated use case this error is the indication of abstract methods that should be implemented on inherited classes, you can use it anyhow you'd like, like for indication of a TODO marker.

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

The format you've used is not recognized by strtotime(). Replace

$date = "04-15-2013";

by

$date = "04/15/2013";

Or if you want to use - then use the following line with the year in front:

$date = "2013-04-15";

i got the same problem after clicking update plugins, i tried all the suggestions above and failed , the only thing that worked for my is reinstalling android studio..

I know that are are a lot of solution for this issue. The best and the easiest solution is to add .htaccess file in the root directory.

I tried the answers that we provided for this issue however I faced some issues with auth:api guard in Laravel.

Here's the updated solution:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On
    RewriteCond %{HTTP:Authorization} ^(.*)
    RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]

    RewriteCond %{REQUEST_FILENAME} -d [OR]
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ ^$1 [N]

    RewriteCond %{REQUEST_URI} (\.\w+$) [NC]
    RewriteRule ^(.*)$ public/$1

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ server.php
</IfModule>

Create the .htaccess file in your root directory and add this code. And everything goes right

In my case I'd simply forgotten I had a binding set up for (in my case) https://localhost:44300 in full IIS. You can't have both!

React Hooks FAQ official solution for forceUpdate:

I've been told that Source.fromFile is problematic. Personally, I have had problems opening large files with Source.fromFile and have had to resort to Java InputStreams.

Another interesting solution is using scalax. Here's an example of some well commented code that opens a log file using ManagedResource to open a file with scalax helpers: http://pastie.org/pastes/420714

in my case, creating an empty column and setting its accessor worked fine. my accessor filling user's age from dob column. toArray() function worked too.

public function getAgeAttribute()
{
  return Carbon::createFromFormat('Y-m-d', $this->attributes['dateofbirth'])->age;
}

In that case you should use ListBox control instead of dropdown and Set the SelectionMode property to Multiple

<asp:ListBox runat="server" SelectionMode="Multiple" >
  <asp:ListItem Text="test1"></asp:ListItem>
  <asp:ListItem Text="test2"></asp:ListItem>
  <asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>

We had the same problem on a CentOS7 machine. Disabling the VERIFYHOST VERIFYPEER did not solve the problem, we did not have the cURL error anymore but the response still was invalid. Doing a wget to the same link as the cURL was doing also resulted in a certificate error.

-> Our solution also was to reboot the VPS, this solved it and we were able to complete the request again.

For us this seemed to be a memory corruption problem. Rebooting the VPS reloaded the libary in the memory again and now it works. So if the above solution from @clover does not work try to reboot your machine.

Simply pass latitude, longitude and your Google API Key to the following query string, you will get a json array, fetch your city from there.

https://maps.googleapis.com/maps/api/geocode/json?latlng=44.4647452,7.3553838&key=YOUR_API_KEY

Note: Ensure that no space exists between the latitude and longitude values when passed in the latlng parameter.

Surely it's a little extreme to say

...never use a for in loop to enumerate over an array. Never. Use good old for(var i = 0; i<arr.length; i++)

?

It is worth highlighting the section in the Douglas Crockford extract

...The second form should be used with objects...

If you require an associative array ( aka hashtable / dictionary ) where keys are named instead of numerically indexed, you will have to implement this as an object, e.g. var myAssocArray = {key1: "value1", key2: "value2"...};.

In this case myAssocArray.length will come up null (because this object doesn't have a 'length' property), and your i < myAssocArray.length won't get you very far. In addition to providing greater convenience, I would expect associative arrays to offer performance advantages in many situations, as the array keys can be useful properties (i.e. an array member's ID property or name), meaning you don't have to iterate through a lengthy array repeatedly evaluating if statements to find the array entry you're after.

Anyway, thanks also for the explanation of the JSLint error messages, I will use the 'isOwnProperty' check now when interating through my myriad associative arrays!

htmlentities — Convert all applicable characters to HTML entities.

htmlspecialchars — Convert special characters to HTML entities.

The translations performed translation characters on the below:

• '&' (ampersand) becomes '&amp;'
• '"' (double quote) becomes '&quot;' when ENT_NOQUOTES is not set.
• "'" (single quote) becomes '&#039;' (or ') only when ENT_QUOTES is set.
• '<' (less than) becomes '&lt;'
• '>' (greater than) becomes '&gt;'

You can check the following code for more information about what's htmlentities and htmlspecialchars:

Hera's the function UpdateWindowsList_WindowMenu() that you must call after any operations are performed on Tabs.Here windowToolStripMenuItem is the menu item added to Window Menu to menu strip.

public void UpdateWindowsList_WindowMenu()  
{  
    //get all tab pages from tabControl1  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  

    //get  windowToolStripMenuItem drop down menu items count  
    int n = windowToolStripMenuItem.DropDownItems.Count;  

    //remove all menu items from of windowToolStripMenuItem  
    for (int i = n - 1; i >=2; i--)  
    {  
        windowToolStripMenuItem.DropDownItems.RemoveAt(i);  
    }  

    //read each tabpage from tabcoll and add each tabpage text to windowToolStripMenuItem  
    foreach (TabPage tabpage in tabcoll)  
    {  
        //create Toolstripmenuitem  
        ToolStripMenuItem menuitem = new ToolStripMenuItem();  
        String s = tabpage.Text;  
        menuitem.Text = s;  

        if (tabControl1.SelectedTab == tabpage)  
        {  
            menuitem.Checked = true;  
        }  
        else  
        {  
            menuitem.Checked = false;  
        }  

        //add menuitem to windowToolStripMenuItem  
        windowToolStripMenuItem.DropDownItems.Add(menuitem);  

        //add click events to each added menuitem  
        menuitem.Click += new System.EventHandler(WindowListEvent_Click);  
    }  
}  

private void WindowListEvent_Click(object sender, EventArgs e)  
{  
    //casting ToolStripMenuItem to ToolStripItem  
    ToolStripItem toolstripitem = (ToolStripItem)sender;  

    //create collection of tabs of tabContro1  
    //check every tab text is equal to clicked menuitem then select the tab  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  
    foreach (TabPage tb in tabcoll)  
    {  
        if (toolstripitem.Text == tb.Text)  
        {  
            tabControl1.SelectedTab = tb;  
            //call UpdateWindowsList_WindowMenu() to perform changes on menuitems  
            UpdateWindowsList_WindowMenu();  
        }  
    }  
}  

jQuery out of the box doesn't have the equivalent of a createElement. In fact the majority of jQuery's work is done internally using innerHTML over pure DOM manipulation. As Adam mentioned above this is how you can achieve similar results.

There are also plugins available that make use of the DOM over innerHTML like appendDOM, DOMEC and FlyDOM just to name a few. Performance wise the native jquery is still the most performant (mainly becasue it uses innerHTML)

Memoization is the conversion of functions into data structures. Usually one wants the conversion to occur incrementally and lazily (on demand of a given domain element--or "key"). In lazy functional languages, this lazy conversion can happen automatically, and thus memoization can be implemented without (explicit) side-effects.

When a function call is invoked by a Java application, a stack frame is allocated on the call stack. The stack frame contains the parameters of the invoked method, its local parameters, and the return address of the method.

The return address denotes the execution point from which, the program execution shall continue after the invoked method returns. If there is no space for a new stack frame then, the StackOverflowError is thrown by the Java Virtual Machine (JVM).

The most common case that can possibly exhaust a Java application’s stack is recursion.

Please Have a look

How to solve StackOverflowError

The problem is using with statement:

with open('strings.json') as json_data:
    d = json.load(json_data)
    pprint(d)

The file is going to be implicitly closed already. There is no need to call json_data.close() again.

Just to add , if you are performing a "pip" operation , you might need to add and additional "--proxy=localhost:port_number"

e.g pip install --proxy=localhost:3128 matplotlib

why You don't use Ajax to

its simple and does not require page refresh and has success and error callbacks

take look at my samlpe

<a id="ResendVerificationCode" >@Resource_en.ResendVerificationCode</a>

and in JQuery

 $("#ResendVerificationCode").on("click", function() {
                getUserbyPhoneIfNotRegisterd($("#phone").val());
 });

and this is my ajax which call my controller and my controller and return object from database

function getUserbyPhoneIfNotRegisterd(userphone) {

              $.ajax({
                    type: "GET",
                    dataType: "Json",
                    url: '@Url.Action("GetUserByPhone", "User")' + '?phone=' + userphone,
                    async: false,
                    success: function(data) {
                        if (data == null || data.data == null) {
                            ErrorMessage("", "@Resource_en.YourPhoneDoesNotExistInOurDatabase");
                        } else {
                            user = data[Object.keys(data)[0]];
                                AddVereCode(user.ID);// anather Ajax call 
                                SuccessMessage("Done", "@Resource_en.VerificationCodeSentSuccessfully", "Done");
                        }
                    },
                    error: function() {
                        ErrorMessage("", '@Resource_en.ErrorOccourd');
                    }
                });
            }

Do you want to pass parameters to another page or to the function only?

If only the function, you don't need to add the $.ajax() tvanfosson added. Just add your function content instead. Like:

function DoAction (id, name ) {
    // ...
    // do anything you want here
    alert ("id: "+id+" - name: "+name);
    //...
}

This will return an alert box with the id and name values.

In newer versions change was made to the flags: from the documentation:

--extended-insert, -e

Write INSERT statements using multiple-row syntax that includes several VALUES lists. This results in a smaller dump file and speeds up inserts when the file is reloaded.

--opt

This option, enabled by default, is shorthand for the combination of --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset. It gives a fast dump operation and produces a dump file that can be reloaded into a MySQL server quickly.

Because the --opt option is enabled by default, you only specify its converse, the --skip-opt to turn off several default settings. See the discussion of mysqldump option groups for information about selectively enabling or disabling a subset of the options affected by --opt.

--skip-extended-insert

Turn off extended-insert

The opposite of :hover appears to be :link.

(edit: not technically an opposite because there are 4 selectors :link, :visited, :hover and :active. Five if you include :focus.)

For example when defining a rule .button:hover{ text-decoration:none } to remove the underline on a button, the underline shows up when you roll off the button in some browsers. I've fixed this with .button:hover, .button:link{ text-decoration:none }

This of course only works for elements that are actually links (have href attribute)

Another no-regex solution that works well on Python 3

# Split strings and keep separator
test_strings = ['<Hello>', 'Hi', '<Hi> <Planet>', '<', '']

def split_and_keep(s, sep):
   if not s: return [''] # consistent with string.split()

   # Find replacement character that is not used in string
   # i.e. just use the highest available character plus one
   # Note: This fails if ord(max(s)) = 0x10FFFF (ValueError)
   p=chr(ord(max(s))+1) 

   return s.replace(sep, sep+p).split(p)

for s in test_strings:
   print(split_and_keep(s, '<'))


# If the unicode limit is reached it will fail explicitly
unicode_max_char = chr(1114111)
ridiculous_string = '<Hello>'+unicode_max_char+'<World>'
print(split_and_keep(ridiculous_string, '<'))

You probably need to update your pg_hba.conf file. This file controls what users can log in from what IP addresses. I think that the postgres user is pretty locked-down by default.

Actually, you can call http://api.hostip.info/?ip=123.125.114.144 to get the information, which is presented in XML.

The usual way to submit a form in general is to call submit() on the form itself, as described in krtek's answer.

However, if you need to actually click a submit button for some reason (your code depends on the submit button's name/value being posted or something), you can click on the submit button itself like this:

document.getElementById('loginSubmit').click();

Also worth mentioning is the GUI cProfile dump viewer RunSnakeRun. It allows you to sort and select, thereby zooming in on the relevant parts of the program. The sizes of the rectangles in the picture is proportional to the time taken. If you mouse over a rectangle it highlights that call in the table and everywhere on the map. When you double-click on a rectangle it zooms in on that portion. It will show you who calls that portion and what that portion calls.

The descriptive information is very helpful. It shows you the code for that bit which can be helpful when you are dealing with built-in library calls. It tells you what file and what line to find the code.

Also want to point at that the OP said 'profiling' but it appears he meant 'timing'. Keep in mind programs will run slower when profiled.

matches tries to match the expression against the entire string and implicitly add a ^ at the start and $ at the end of your pattern, meaning it will not look for a substring. Hence the output of this code:

public static void main(String[] args) throws ParseException {
    Pattern p = Pattern.compile("\\d\\d\\d");
    Matcher m = p.matcher("a123b");
    System.out.println(m.find());
    System.out.println(m.matches());

    p = Pattern.compile("^\\d\\d\\d$");
    m = p.matcher("123");
    System.out.println(m.find());
    System.out.println(m.matches());
}

/* output:
true
false
true
true
*/

123 is a substring of a123b so the find() method outputs true. matches() only 'sees' a123b which is not the same as 123 and thus outputs false.

Usually the application that misses the .dll indicates what version you need – if one does not work, simply download the Microsoft visual C++ 2010 x86 or x64 from this link:

You could avoid changing the code (although I recommend Boris' answer) and mock the constructor, like in this example for mocking the creation of a File object inside a method. Don't forget to put the class that will create the file in the @PrepareForTest.

package hello.easymock.constructor;

import java.io.File;

import org.easymock.EasyMock;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
    
@RunWith(PowerMockRunner.class)
@PrepareForTest({File.class})
public class ConstructorExampleTest {
        
    @Test
    public void testMockFile() throws Exception {

        // first, create a mock for File
        final File fileMock = EasyMock.createMock(File.class);
        EasyMock.expect(fileMock.getAbsolutePath()).andReturn("/my/fake/file/path");
        EasyMock.replay(fileMock);

        // then return the mocked object if the constructor is invoked
        Class<?>[] parameterTypes = new Class[] { String.class };
        PowerMock.expectNew(File.class, parameterTypes , EasyMock.isA(String.class)).andReturn(fileMock);
        PowerMock.replay(File.class); 
    
        // try constructing a real File and check if the mock kicked in
        final String mockedFilePath = new File("/real/path/for/file").getAbsolutePath();
        Assert.assertEquals("/my/fake/file/path", mockedFilePath);
    }
}

Just use padding to wrap it like this:

Column(
  children: <Widget>[
  Padding(
    padding: EdgeInsets.all(8.0),
    child: Text('Hello World!'),
  ),
  Padding(
    padding: EdgeInsets.all(8.0),
    child: Text('Hello World2!'),
  )
]);

You can also use Container(padding...) or SizeBox(height: x.x). The last one is the most common but it will depents of how you want to manage the space of your widgets, I like to use padding if the space is part of the widget indeed and use sizebox for lists for example.

A POST is considered something of a factory type method. You include data with it to create what you want and whatever is on the other end knows what to do with it. A PUT is used to update existing data at a given URL, or to create something new when you know what the URI is going to be and it doesn't already exist (as opposed to a POST which will create something and return a URL to it if necessary).

Update: The code in this answer is for Super CSV 1.52. Updated code examples for Super CSV 2.4.0 can be found at the project website: http://super-csv.github.io/super-csv/index.html

The SuperCSV project directly supports the parsing and structured manipulation of CSV cells. From http://super-csv.github.io/super-csv/examples_reading.html you'll find e.g.

given a class

public class UserBean {
    String username, password, street, town;
    int zip;

    public String getPassword() { return password; }
    public String getStreet() { return street; }
    public String getTown() { return town; }
    public String getUsername() { return username; }
    public int getZip() { return zip; }
    public void setPassword(String password) { this.password = password; }
    public void setStreet(String street) { this.street = street; }
    public void setTown(String town) { this.town = town; }
    public void setUsername(String username) { this.username = username; }
    public void setZip(int zip) { this.zip = zip; }
}

and that you have a CSV file with a header. Let's assume the following content

username, password,   date,        zip,  town
Klaus,    qwexyKiks,  17/1/2007,   1111, New York
Oufu,     bobilop,    10/10/2007,  4555, New York

You can then create an instance of the UserBean and populate it with values from the second line of the file with the following code

class ReadingObjects {
  public static void main(String[] args) throws Exception{
    ICsvBeanReader inFile = new CsvBeanReader(new FileReader("foo.csv"), CsvPreference.EXCEL_PREFERENCE);
    try {
      final String[] header = inFile.getCSVHeader(true);
      UserBean user;
      while( (user = inFile.read(UserBean.class, header, processors)) != null) {
        System.out.println(user.getZip());
      }
    } finally {
      inFile.close();
    }
  }
}

using the following "manipulation specification"

final CellProcessor[] processors = new CellProcessor[] {
    new Unique(new StrMinMax(5, 20)),
    new StrMinMax(8, 35),
    new ParseDate("dd/MM/yyyy"),
    new Optional(new ParseInt()),
    null
};

Scanner scanner = new Scanner(System.in);
String part = scanner.nextLine();
String line = scanner.nextLine();

String temp = "\\b" + part +"|"+ part + "\\b";
Pattern pattern = Pattern.compile(temp.toLowerCase());
Matcher matcher = pattern.matcher(line.toLowerCase());

System.out.println(matcher.find() ? "YES":"NO");

If you need to determine if any of the words of this text start or end with the sequence. you can use this regex \bsubstring|substring\b anythingsubstring substringanything anythingsubstringanything

Perhaps I'm completely missing the point of this question, but you want to find an integer missing from a sorted file of integers?

Uhh... really? Let's think about what such a file would look like:

1 2 3 4 5 6 ... first missing number ... etc.

The solution to this problem seems trivial.

I know this question is quite old, but that's what actually worked for me:

git commit --date="10 day ago" -m "Your commit message" 

The Web Storage API provides mechanisms by which browsers can securely store key/value pairs, in a much more intuitive fashion than using cookies. The Web Storage API extends the Window object with two new properties — Window.sessionStorage and Window.localStorage. — invoking one of these will create an instance of the Storage object, through which data items can be set, retrieved, and removed. A different Storage object is used for the sessionStorage and localStorage for each origin (domain).

Storage objects are simple key-value stores, similar to objects, but they stay intact through page loads.

localStorage.colorSetting = '#a4509b';
localStorage['colorSetting'] = '#a4509b';
localStorage.setItem('colorSetting', '#a4509b');

The keys and the values are always strings. To store any type convert it to String and then store it. It's always recommended to use Storage interface methods.

var testObject = { 'one': 1, 'two': 2, 'three': 3 };
// Put the object into storage
localStorage.setItem('testObject', JSON.stringify(testObject));
// Retrieve the object from storage
var retrievedObject = localStorage.getItem('testObject');
console.log('Converting String to Object: ', JSON.parse(retrievedObject));

The two mechanisms within Web Storage are as follows:

• sessionStorage maintains a separate storage area for each given origin^{Same-origin policy} that's available for the duration of the page session (as long as the browser is open, including page reloads and restores).
• localStorage does the same thing, but persists even when the browser is closed and reopened.

Storage « Local storage writes the data to the disk, while session storage writes the data to the memory only. Any data written to the session storage is purged when your app exits.

The maximum storage available is different per browser, but most browsers have implemented at least the w3c recommended maximum storage limit of 5MB.

+----------------+--------+---------+-----------+--------+
|                | Chrome | Firefox | Safari    |  IE    |
+----------------+--------+---------+-----------+--------+
| LocalStorage   | 10MB   | 10MB    | 5MB       | 10MB   |
+----------------+--------+---------+-----------+--------+
| SessionStorage | 10MB   | 10MB    | Unlimited | 10MB   |
+----------------+--------+---------+-----------+--------+

Always catch LocalStorage security and quota exceeded errors

• QuotaExceededError: When storage limits exceeds on this function window.sessionStorage.setItem(key, value);, it throws a "QuotaExceededError" DOMException exception if the new value couldn't be set. (Setting could fail if, e.g., the user has disabled storage for the site, or if the quota has been exceeded.)

  DOMException.QUOTA_EXCEEDED_ERR is 22, example fiddle.

• SecurityError : Uncaught SecurityError: Access to 'localStorage' is denied for this document.

   CHROME:-Privacy and security « Content settings « Cookies « Block third-party cookies.
  

StorageEvent « The storage event is fired on a document's Window object when a storage area changes. When a user agent is to send a storage notification for a Document, the user agent must queue a task to fire an event named storage at the Document object's Window object, using StorageEvent.

Note: For a real world example, see Web Storage Demo. ^{check out the source code}

Listen to the storage event on dom/Window to catch changes in the storage. fiddle.

Cookies (web cookie, browser cookie) Cookies are data, stored in small text files as name-value pairs, on your computer.

JavaScript access using Document.cookie

New cookies can also be created via JavaScript using the Document.cookie property, and if the HttpOnly flag is not set, existing cookies can be accessed from JavaScript as well.

document.cookie = "yummy_cookie=choco"; 
document.cookie = "tasty_cookie=strawberry"; 
console.log(document.cookie); 
// logs "yummy_cookie=choco; tasty_cookie=strawberry"

Secure and HttpOnly cookies ^{HTTP State Management Mechanism}

Cookies are often used in web application to identify a user and their authenticated session

When receiving an HTTP request, a server can send a Set-Cookie header with the response. The cookie is usually stored by the browser, and then the cookie is sent with requests made to the same server inside a Cookie HTTP header.

Set-Cookie: <cookie-name>=<cookie-value> 
Set-Cookie: <cookie-name>=<cookie-value>; Expires=<date>

Session cookies will get removed when the client is shut down. They don't specify the Expires or Max-Age directives.

Set-Cookie: sessionid=38afes7a8; HttpOnly; Path=/

Permanent cookies expire at a specific date (Expires) or after a specific length of time (Max-Age).

Set-Cookie: id=a3fWa; Expires=Wed, 21 Oct 2015 07:28:00 GMT; Secure; HttpOnly

The Cookie HTTP request header contains stored HTTP cookies previously sent by the server with the Set-Cookie header. HTTP-only cookies aren't accessible via JavaScript through the Document.cookie property, the XMLHttpRequest and Request APIs to mitigate attacks against cross-site scripting (XSS).

Cookies are mainly used for three purposes:

• Session management « Logins, shopping carts, game scores, or anything else the server should remember
• Personalization « User preferences, themes, and other settings
• Tracking (Recording and analyzing user behavior) « Cookies have a domain associated to them. If this domain is the same as the domain of the page you are on, the cookies is said to be a first-party cookie. If the domain is different, it is said to be a third-party cookie. While first-party cookies are sent only to the server setting them, a web page may contain images or other components stored on servers in other domains (like ad banners). Cookies that are sent through these third-party components are called third-party cookies and are mainly used for advertising and tracking across the web.

Cookies were invented to solve the problem "how to remember information about the user":

• When a user visits a web page, his name can be stored in a cookie.
• Next time the user visits the page, cookies belonging to the page is added to the request. This way the server gets the necessary data to "remember" information about users.

GitHubGist Example

As summary,

• localStorage persists over different tabs or windows, and even if we close the browser, accordingly with the domain security policy and user choices about quota limit.
• sessionStorage object does not persist if we close the tab (top-level browsing context) as it does not exists if we surf via another tab or window.
• Web Storage (session, local) allows us to save a large amount of key/value pairs and lots of text, something impossible to do via cookie.
• Cookies that are used for sensitive actions should have a short lifetime only.
• Cookies mainly used for advertising and tracking across the web. See for example the types of cookies used by Google.
• Cookies are sent with every request, so they can worsen performance (especially for mobile data connections). Modern APIs for client storage are the Web storage API (localStorage and sessionStorage) and IndexedDB.

Updated code

$('a','div.res').click(function(){
  var currentAnchor = $(this);
  alert(currentAnchor.text());
  alert(currentAnchor.attr('href'));
});

I prefer to this way:

   /**
     *
     * @param host
     * @return true means ping success,false means ping fail.
     * @throws IOException
     * @throws InterruptedException
     */
    private static boolean ping(String host) throws IOException, InterruptedException {
        boolean isWindows = System.getProperty("os.name").toLowerCase().contains("win");

        ProcessBuilder processBuilder = new ProcessBuilder("ping", isWindows? "-n" : "-c", "1", host);
        Process proc = processBuilder.start();
        return proc.waitFor(200, TimeUnit.MILLISECONDS);
    }

This way can limit the blocking time to the specific time,such as 200 ms.

It works well in MacOS?Android and Windows, but should used in JDK 1.8.

This idea comes from Mohammad Banisaeid,but I can't comment. (You must have 50 reputation to comment)

The error message is confusing for one big reason:

Primitive type names are not reserved in PHP

The following are all valid class declarations:

class string { }
class int { }
class float { }
class double { }

My mistake was in thinking that the error message was referring solely to the string primitive type - the word 'instance' should have given me pause. An example to illustrate further:

class string { }
$n = 1234;
$s1 = (string)$n;
$s2 = new string();
$a = array('no', 'yes');
printf("\$s1 - primitive string? %s - string instance? %s\n",
        $a[is_string($s1)], $a[is_a($s1, 'string')]);
printf("\$s2 - primitive string? %s - string instance? %s\n",
        $a[is_string($s2)], $a[is_a($s2, 'string')]);

Output:

$s1 - primitive string? yes - string instance? no

$s2 - primitive string? no - string instance? yes

In PHP it's possible for a string to be a string except when it's actually a string. As with any language that uses implicit type conversion, context is everything.

This copies the 5 cells to the right of the activecell. If you have a range selected, the active cell is the top left cell in the range.

Sub Copy5CellsToRight()
    ActiveCell.Offset(, 1).Resize(1, 5).Copy
End Sub

If you want to include the activecell in the range that gets copied, you don't need the offset:

Sub ExtendAndCopy5CellsToRight()
    ActiveCell.Resize(1, 6).Copy
End Sub

Note that you don't need to select before copying.

All you need to do is set the PATH environment variable in Windows to point to where your java6 bin directory is instead of the java7 directory.

Right click My Computer > Advanced System Settings > Advanced > Environmental Variables

If there is a JAVA_HOME environment variable set this to point to the correct directory as well.

this worked for me ... Android > Gradle Scripts > build.gradle (Module:app) add inside android*

android {
  //   compileSdkVersion 27
     defaultConfig {
        //
     }
     buildTypes {
        //
     }
    // buildToolsVersion '27.0.3'

    splits {

                 universalApk true
               }
    }
 }

Like this:

from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key

Or, using the method syntax:

Company
    .GroupBy(c => c.Name)
    .Where(grp => grp.Count() > 1)
    .Select(grp => grp.Key);

NR starts at 1, so use

awk '{print NR-1 "," $0}'

Use your own HTTPS-to-HTTP reverse proxy.

If your use case is about a few, rarely changing URLs to embed into the iframe, you can simply set up a reverse proxy for this on your own server and configure it so that one https URL on your server maps to one http URL on the proxied server. Since a reverse proxy is fully serverside, the browser cannot discover that it is "only" talking to a proxy of the real website, and thus will not complain as the connection to the proxy uses SSL properly.

If for example you use Apache2 as your webserver, then see these instructions to create a reverse proxy.

If it fits your purpose you can add the hover functionality without using css and using the onmouseover event in javascript

Here is a code snippet

<div id="mydiv">foo</div>

<script>
document.getElementById("mydiv").onmouseover = function() 
{
    this.style.backgroundColor = "blue";
}
</script>

If you are designing your Javafx application using SceneBuilder then use -fx-text-fill(if not available as option then write it in style input box) as style and give the color you want,it will change the text color of your Textfield.

I came here for the same problem and solved it in this way.

You cannot. By design, for security purpose, you can access only the cookies set by your site. StackOverflow can't see the cookies set by UserVoice nor those set by Amazon.

In Android Studio resolved it by

1. Navigate to File > Editor > File Encodings.
2. In global encoding set the encoding to ISO-8859-1
3. In Project encoding set the encoding to UTF-8 and the same case to Default encoding for properties files.
4. Rebuild project.

When using an iframe, you will first have to switch to the iframe, before selecting the elements of that iframe

You can do it using:

driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();

In case if your frameId is dynamic, and you only have one iframe, you can use something like:

driver.switchTo().frame(driver.findElement(By.tagName("iframe")));

has_key has been deprecated in Python 3.0. Alternatively you can use 'in'

graph={'A':['B','C'],
   'B':['C','D']}

print('A' in graph)
>> True

print('E' in graph)
>> False

There is no str accessor for datetimes and you can't do dates.astype(str) either, you can call apply and use datetime.strftime:

In [73]:

dates = pd.to_datetime(pd.Series(['20010101', '20010331']), format = '%Y%m%d')
dates.apply(lambda x: x.strftime('%Y-%m-%d'))
Out[73]:
0    2001-01-01
1    2001-03-31
dtype: object

You can change the format of your date strings using whatever you like: strftime() and strptime() Behavior.

Update

As of version 0.17.0 you can do this using dt.strftime

dates.dt.strftime('%Y-%m-%d')

will now work

The question is tagged WPF but the answers so far are specific WinForms and Win32.

To do this in WPF, simply construct a KeyEventArgs and call RaiseEvent on the target. For example, to send an Insert key KeyDown event to the currently focused element:

var key = Key.Insert;                    // Key to send
var target = Keyboard.FocusedElement;    // Target element
var routedEvent = Keyboard.KeyDownEvent; // Event to send
     target.RaiseEvent(
  new KeyEventArgs(
    Keyboard.PrimaryDevice,
    PresentationSource.FromVisual(target),
    0,
    key)
  { RoutedEvent=routedEvent }
);

This solution doesn't rely on native calls or Windows internals and should be much more reliable than the others. It also allows you to simulate a keypress on a specific element.

Note that this code is only applicable to PreviewKeyDown, KeyDown, PreviewKeyUp, and KeyUp events. If you want to send TextInput events you'll do this instead:

var text = "Hello";
var target = Keyboard.FocusedElement;
var routedEvent = TextCompositionManager.TextInputEvent;

target.RaiseEvent(
  new TextCompositionEventArgs(
    InputManager.Current.PrimaryKeyboardDevice,
    new TextComposition(InputManager.Current, target, text))
  { RoutedEvent = routedEvent }
);

Also note that:

• Controls expect to receive Preview events, for example PreviewKeyDown should precede KeyDown

• Using target.RaiseEvent(...) sends the event directly to the target without meta-processing such as accelerators, text composition and IME. This is normally what you want. On the other hand, if you really do what to simulate actual keyboard keys for some reason, you would use InputManager.ProcessInput() instead.

Well, since your on a shared server, you can't do anything about it. They usually set the max execution time so that you can't override it. I suggest you contact them.

This error could also appear if you are having network latency or internet or local network problems. Bridged connections that have a failing counterpart may be the culprit as well.

The steps are as follows :

1. Close WAMP (if running)
2. Navigate to WAMP\bin\php\(your version of php)\
3. Edit php.ini
4. Search for curl, uncomment extension=php_curl.dll
5. Navigate to WAMP\bin\Apache\(your version of apache)\bin\
6. Edit php.ini
7. Search for curl, uncomment extension=php_curl.dll
8. Save both
9. Restart WAMP

You get this error if you have constrained T to being a class

The simplest and efficient solution is :

pgrep -fl aa.sh

If you are concerned about Unicode characters you can use ASCII to build the structures, so your example structure becomes

Which is similar to the format tree uses if you select ANSI output.

those are miliseconds, just divide them by 1000, since gmtime expects seconds ...

Apparently with Laravel 5.2, the closure in DB::listen only receives a single parameter.

So, if you want to use DB::listen in Laravel 5.2, you should do something like:

DB::listen(
    function ($sql) {
        // $sql is an object with the properties:
        //  sql: The query
        //  bindings: the sql query variables
        //  time: The execution time for the query
        //  connectionName: The name of the connection

        // To save the executed queries to file:
        // Process the sql and the bindings:
        foreach ($sql->bindings as $i => $binding) {
            if ($binding instanceof \DateTime) {
                $sql->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
            } else {
                if (is_string($binding)) {
                    $sql->bindings[$i] = "'$binding'";
                }
            }
        }

        // Insert bindings into query
        $query = str_replace(array('%', '?'), array('%%', '%s'), $sql->sql);

        $query = vsprintf($query, $sql->bindings);

        // Save the query to file
        $logFile = fopen(
            storage_path('logs' . DIRECTORY_SEPARATOR . date('Y-m-d') . '_query.log'),
            'a+'
        );
        fwrite($logFile, date('Y-m-d H:i:s') . ': ' . $query . PHP_EOL);
        fclose($logFile);
    }
);

The accepted answer of using npm-install-peers did not work, nor removing node_modules and rebuilding. The answer to run

npm install --save-dev @xxxxx/xxxxx@latest

for each one, with the xxxxx referring to the exact text in the peer warning, worked. I only had four warnings, if I had a dozen or more as in the question, it might be a good idea to script the commands.

In Python 3 it is a function, but in Python 2 you can add this to the top of the source file:

from __future__ import print_function

Then you do

print("hi there", file=f)

In my case, I was fetching data from database, changing some column values and updating it in database but for updating I was using the same save query which was violating primary key constraints i.e duplicate values for primary key, so I had written a separate query for updating the columns and it solved my problem..!

Try this one:

echo "$(ps -ceo pid=,comm= | awk '/firefox/ { print $1; exit }')"

The ps command produces output like this, with the PID in the first column and the executable name (only) in the second column:

bookworm% ps -ceo pid=,comm=
    1 launchd
   10 kextd
   11 UserEventAgent
   12 mDNSResponder
   13 opendirectoryd
   14 notifyd
   15 configd

...which awk processes, printing the first column (pid) and exiting after the first match.

For simplicity's sake: newList = list(set(oldList))

But there are better options out there if you'd like to get speed/ordering/optimization instead: http://www.peterbe.com/plog/uniqifiers-benchmark

You can do this locally as everyone mentioned using

git checkout -b <branch-name> <sha1-of-commit>

Alternatively, you can do this in github itself, follow the steps:

1- In the repository, click on the Commits.

2- on the commit you want to branch from, click on <> to browse the repository at this point in the history.

3- Click on the tree: xxxxxx in the upper left. Just type in a new branch name there click Create branch xxx as shown below.

Now you can fetch the changes from that branch locally and continue from there.

If the end of sequence has maximal length of padding (for example, if you want 5 digits and command is "seq 1 10000"), than you can use "-w" flag for seq - it adds padding itself.

$variable[0] != "_"

How does it work?

In PHP you can get particular character of a string with array index notation. $variable[0] is the first character of a string (if $variable is a string).

Just to clarify: from within your app, you can simply refer to the emulator as 'localhost' or 127.0.0.1.

Web traffic is routed through your development machine, so the emulator's external IP is whatever IP has been assigned to that machine by your provider. The development machine can always be reached from your device at 10.0.2.2.

Since you were asking only about the emulator's IP, what is it you're trying to do?

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

docker tag CURRENT_IMAGE_NAME DESIRED_IMAGE_NAME

Set FormBorderStyle to 'FixedDialog'

For those who want single command SQL query for that:

INSERT INTO TABLE002 
(COL001_MEM_ID, COL002_MEM_NAME, COL002_MEM_ADD, COL002_CREATE_USER_C, COL002_CREATE_S)
SELECT COL001_MEM_ID, COL001_MEM_NAME, COL001_MEM_ADD, COL001_CREATE_USER_C, COL001_CREATE_S
FROM TABLE001;

This query will copy data from TABLE001 to TABLE002 and we assume that both columns had different column names.

Column names are mapped one-to-one like:

COL001_MEM_ID -> COL001_MEM_ID

COL001_MEM_NAME -> COL002_MEM_NAME

COL001_MEM_ADD -> COL002_MEM_ADD

COL001_CREATE_USER_C -> COL002_CREATE_USER_C

COL002_CREATE_S -> COL002_CREATE_S

You can also specify where clause, if you need some condition.

You can assign one color to every functionality to make it more useful.

#define Color_Red "\33[0:31m\\]" // Color Start
#define Color_end "\33[0m\\]" // To flush out prev settings
#define LOG_RED(X) printf("%s %s %s",Color_Red,X,Color_end)

foo()
{
LOG_RED("This is in Red Color");
}

Like wise you can select different color codes and make this more generic.

With Swift 5, you can choose one of the two following Playground code samples in order to animate your UILabel's text changes with some cross dissolve animation.

#1. Using UIView's transition(with:duration:options:animations:completion:) class method

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let label = UILabel()

    override func viewDidLoad() {
        super.viewDidLoad()

        label.text = "Car"

        view.backgroundColor = .white
        view.addSubview(label)

        label.translatesAutoresizingMaskIntoConstraints = false
        label.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        label.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(toggle(_:)))
        view.addGestureRecognizer(tapGesture)
    }

    @objc func toggle(_ sender: UITapGestureRecognizer) {
        let animation = {
            self.label.text = self.label.text == "Car" ? "Plane" : "Car"
        }
        UIView.transition(with: label, duration: 2, options: .transitionCrossDissolve, animations: animation, completion: nil)
    }

}

let controller = ViewController()
PlaygroundPage.current.liveView = controller

#2. Using CATransition and CALayer's add(_:forKey:) method

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let label = UILabel()
    let animation = CATransition()

    override func viewDidLoad() {
        super.viewDidLoad()

        label.text = "Car"

        animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
        // animation.type = CATransitionType.fade // default is fade
        animation.duration = 2

        view.backgroundColor = .white
        view.addSubview(label)

        label.translatesAutoresizingMaskIntoConstraints = false
        label.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        label.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(toggle(_:)))
        view.addGestureRecognizer(tapGesture)
    }

    @objc func toggle(_ sender: UITapGestureRecognizer) {
        label.layer.add(animation, forKey: nil) // The special key kCATransition is automatically used for transition animations
        label.text = label.text == "Car" ? "Plane" : "Car"
    }

}

let controller = ViewController()
PlaygroundPage.current.liveView = controller

As Homebrew is my favorite for macOS although it is possible to have apt-get on macOS using Fink.

Try

function RadionButtonSelectedValueSet(name, SelectdValue) {
    $('input[name="' + name+ '"][value="' + SelectdValue + '"]').prop('checked', true);
}

also call the method on dom ready

<script type="text/javascript">
jQuery(function(){
    RadionButtonSelectedValueSet('RBLExperienceApplicable', '1');
})
</script>

I took the liberty of feeding your classes into the CGbR generator. Because it is in an early stage it doesn't support DateTime yet, so I simply replaced it with long. The generated serialization code looks like this:

public int Size
{
    get 
    { 
        var size = 24;
        // Add size for collections and strings
        size += Cts == null ? 0 : Cts.Count * 4;
        size += Tes == null ? 0 : Tes.Count * 4;
        size += Code == null ? 0 : Code.Length;
        size += Message == null ? 0 : Message.Length;

        return size;              
    }
}

public byte[] ToBytes(byte[] bytes, ref int index)
{
    if (index + Size > bytes.Length)
        throw new ArgumentOutOfRangeException("index", "Object does not fit in array");

    // Convert Cts
    // Two bytes length information for each dimension
    GeneratorByteConverter.Include((ushort)(Cts == null ? 0 : Cts.Count), bytes, ref index);
    if (Cts != null)
    {
        for(var i = 0; i < Cts.Count; i++)
        {
            var value = Cts[i];
            value.ToBytes(bytes, ref index);
        }
    }
    // Convert Tes
    // Two bytes length information for each dimension
    GeneratorByteConverter.Include((ushort)(Tes == null ? 0 : Tes.Count), bytes, ref index);
    if (Tes != null)
    {
        for(var i = 0; i < Tes.Count; i++)
        {
            var value = Tes[i];
            value.ToBytes(bytes, ref index);
        }
    }
    // Convert Code
    GeneratorByteConverter.Include(Code, bytes, ref index);
    // Convert Message
    GeneratorByteConverter.Include(Message, bytes, ref index);
    // Convert StartDate
    GeneratorByteConverter.Include(StartDate.ToBinary(), bytes, ref index);
    // Convert EndDate
    GeneratorByteConverter.Include(EndDate.ToBinary(), bytes, ref index);
    return bytes;
}

public Td FromBytes(byte[] bytes, ref int index)
{
    // Read Cts
    var ctsLength = GeneratorByteConverter.ToUInt16(bytes, ref index);
    var tempCts = new List<Ct>(ctsLength);
    for (var i = 0; i < ctsLength; i++)
    {
        var value = new Ct().FromBytes(bytes, ref index);
        tempCts.Add(value);
    }
    Cts = tempCts;
    // Read Tes
    var tesLength = GeneratorByteConverter.ToUInt16(bytes, ref index);
    var tempTes = new List<Te>(tesLength);
    for (var i = 0; i < tesLength; i++)
    {
        var value = new Te().FromBytes(bytes, ref index);
        tempTes.Add(value);
    }
    Tes = tempTes;
    // Read Code
    Code = GeneratorByteConverter.GetString(bytes, ref index);
    // Read Message
    Message = GeneratorByteConverter.GetString(bytes, ref index);
    // Read StartDate
    StartDate = DateTime.FromBinary(GeneratorByteConverter.ToInt64(bytes, ref index));
    // Read EndDate
    EndDate = DateTime.FromBinary(GeneratorByteConverter.ToInt64(bytes, ref index));

    return this;
}

I created a list of sample objects like this:

var objects = new List<Td>();
for (int i = 0; i < 1000; i++)
{
    var obj = new Td
    {
        Message = "Hello my friend",
        Code = "Some code that can be put here",
        StartDate = DateTime.Now.AddDays(-7),
        EndDate = DateTime.Now.AddDays(2),
        Cts = new List<Ct>(),
        Tes = new List<Te>()
    };
    for (int j = 0; j < 10; j++)
    {
        obj.Cts.Add(new Ct { Foo = i * j });
        obj.Tes.Add(new Te { Bar = i + j });
    }
    objects.Add(obj);
}

Results on my machine in Release build:

var watch = new Stopwatch();
watch.Start();
var bytes = BinarySerializer.SerializeMany(objects);
watch.Stop();

Size: 149000 bytes

Time: 2.059ms 3.13ms

Edit: Starting with CGbR 0.4.3 the binary serializer supports DateTime. Unfortunately the DateTime.ToBinary method is insanely slow. I will replace it with somehting faster soon.

Edit2: When using UTC DateTime by invoking ToUniversalTime() the performance is restored and clocks in at 1.669ms.

You should not play with the height. Let the text field determine the height based on the font used.

If you want to control the width of the text field then you can use

textField.setColumns(...);

to let the text field determine the preferred width.

Or if you want the width to be the entire width of the parent panel then you need to use an appropriate layout. Maybe the NORTH of a BorderLayout.

See the Swing tutorial on Layout Managers for more information.

if you just need to load script dont do as bellow

$(document.body).html('<script type="text/javascript" src="/json.js" async="async"><\/script>');

Try this

var scriptEl = document.createElement('SCRIPT');
    scriptEl.src = "/module/script/form?_t="+(new Date()).getTime();
    //$('#holder').append(scriptEl) // <--- create warning
    document.body.appendChild(scriptEl);

There are some libraries around there:

• Commons-BeanUtils: ConvertUtils -> Utility methods for converting String scalar values to objects of the specified Class, String arrays to arrays of the specified Class.

• Commons-Lang: ArrayUtils -> Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).

• Spring framework: Spring has an excellent support for PropertyEditors, that can also be used to transform Objects to/from Strings.

• Dozer: Dozer is a powerful, yet simple Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

• ModelMapper: ModelMapper is an intelligent object mapping framework that automatically maps objects to each other. It uses a convention based approach to map objects while providing a simple refactoring safe API for handling specific use cases.

• MapStruct: MapStruct is a compile-time code generator for bean mappings, resulting in fast (no usage of reflection or similar), dependency-less and type-safe mapping code at runtime.

• Orika: Orika uses byte code generation to create fast mappers with minimal overhead.

• Selma: Compile-time code-generator for mappings

• JMapper: Bean mapper generation using Annotation, XML or API (seems dead, last updated 2 years ago)

• Smooks: The Smooks JavaBean Cartridge allows you to create and populate Java objects from your message data (i.e. bind data to) (suggested by superfilin in comments). (No longer under active development)

• Commons-Convert: Commons-Convert aims to provide a single library dedicated to the task of converting an object of one type to another. The first stage will focus on Object to String and String to Object conversions. (seems dead, last update 2010)

• Transmorph: Transmorph is a free java library used to convert a Java object of one type into an object of another type (with another signature, possibly parameterized). (seems dead, last update 2013)

• EZMorph: EZMorph is simple java library for transforming an Object to another Object. It supports transformations for primitives and Objects, for multidimensional arrays and transformations with DynaBeans (seems dead, last updated 2008)

• Morph: Morph is a Java framework that eases the internal interoperability of an application. As information flows through an application, it undergoes multiple transformations. Morph provides a standard way to implement these transformations. (seems dead, last update 2008)

• Lorentz: Lorentz is a generic object-to-object conversion framework. It provides a simple API to convert a Java objects of one type into an object of another type. (seems dead)

• OTOM: With OTOM, you can copy any data from any object to any other object. The possibilities are endless. Welcome to "Autumn". (seems dead)

For general information on security, I highly recommend reading Bruce Schneier. He's got a website, his crypto-gram newsletter, several books, and has done lots of interviews.

I would also get familiar with social engineering (and Kevin Mitnick).

For a good (and pretty entertaining) book on how security plays out in the real world, I would recommend the excellent (although a bit dated) 'The Cuckoo's Egg' by Cliff Stoll.

You need to use the DataGridViewColumn.AutoSizeMode property.

You can use one of these values for column 0 and 1:

AllCells: The column width adjusts to fit the contents of all cells in the column, including the header cell.
AllCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column, excluding the header cell.
DisplayedCells: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, including the header cell.
DisplayedCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, excluding the header cell.

Then you use the Fill value for column 2

The column width adjusts so that the widths of all columns exactly fills the display area of the control...

this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

As pointed out by other users, the default value can be set at datagridview level with DataGridView.AutoSizeColumnsMode property.

this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;

could be:

this.DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;

Important note:

If your grid is bound to a datasource and columns are auto-generated (AutoGenerateColumns property set to True), you need to use the DataBindingComplete event to apply style AFTER columns have been created.

In some scenarios (change cells value by code for example), I had to call DataGridView1.AutoResizeColumns(); to refresh the grid.

For rolling out products where we need to configure a lot of items with similar values, we use small console apps that read the XML and update based on the parameters passed in. These are then called by the installer after it has asked the user for the required information.

How's this for an explantation to the layman. One way computers represent numbers is by counting discrete units. These are digital computers. For whole numbers, those without a fractional part, modern digital computers count powers of two: 1, 2, 4, 8. ,,, Place value, binary digits, blah , blah, blah. For fractions, digital computers count inverse powers of two: 1/2, 1/4, 1/8, ... The problem is that many numbers can't be represented by a sum of a finite number of those inverse powers. Using more place values (more bits) will increase the precision of the representation of those 'problem' numbers, but never get it exactly because it only has a limited number of bits. Some numbers can't be represented with an infinite number of bits.

Snooze...

OK, you want to measure the volume of water in a container, and you only have 3 measuring cups: full cup, half cup, and quarter cup. After counting the last full cup, let's say there is one third of a cup remaining. Yet you can't measure that because it doesn't exactly fill any combination of available cups. It doesn't fill the half cup, and the overflow from the quarter cup is too small to fill anything. So you have an error - the difference between 1/3 and 1/4. This error is compounded when you combine it with errors from other measurements.

The Kafka clients no longer require zookeeper but the Kafka servers do need it to operate.

You can get a list of topics with the new AdminClient API but the shell command that ship with Kafka have not yet been rewritten to use this new API.

The other way to use Kafka without Zookeeper is to use a SaaS Kafka-as-a-Service provider such as Confluent Cloud so you don’t see or operate the Kafka brokers (and the required backend Zookeeper ensemble).

For example on Confluent Cloud you would just use the following zookeeper free CLI command:

ccloud topic list

There is nothing much to add to your code except appending the li tag to the ul

ul.appendChild(li)

and there you go just add this to your function and then it should work.

import-module Microsoft.Exchange.Management.PowerShell.E2010aTry with some implementation like:

$exchangeser = "MTLServer01"
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionURI http://${exchangeserver}/powershell/ -Authentication kerberos
import-PSSession $session 

or

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

The best way to do this is disable it with webserver apache2. In my Ubuntu 14.X - open /etc/apache2/apache2.conf change from

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to

<Directory /var/www/>
        Options FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

then restart apache by:

sudo service apache2 reload

This will disable directory listing from all folder that apache2 serves.
