You can also customize the card theme globally with ThemeData.cardTheme:

MaterialApp(
  title: 'savvy',
  theme: ThemeData(
    cardTheme: CardTheme(
      shape: RoundedRectangleBorder(
        borderRadius: const BorderRadius.all(
          Radius.circular(8.0),
        ),
      ),
    ),
    // ...

This is working as documented. Any paths specified in PYTHONPATH are documented as normally coming after the working directory but before the standard interpreter-supplied paths. sys.path.append() appends to the existing path. See here and here. If you want a particular directory to come first, simply insert it at the head of sys.path:

import sys
sys.path.insert(0,'/path/to/mod_directory')

That said, there are usually better ways to manage imports than either using PYTHONPATH or manipulating sys.path directly. See, for example, the answers to this question.

In addition to the other answers, there is a big benefit to using the DisplayAttribute when you want to localize the fields. You can lookup the name in a localization database using the DisplayAttribute and it will use whatever translation you wish.

Also, you can let MVC generate the templates for you by using Html.EditorForModel() and it will generate the correct label for you.

Ultimately, it's up to you. But the MVC is very "Model-centric", which is why data attributes are applied to models, so that metadata exists in a single place. It's not like it's a huge amount of extra typing you have to do.

The domain name portion of a URL is not case sensitive since DNS ignores case: http://en.example.org/ and HTTP://EN.EXAMPLE.ORG/ both open the same page.

The path is used to specify and perhaps find the resource requested. It is case-sensitive, though it may be treated as case-insensitive by some servers, especially those based on Microsoft Windows.

If the server is case sensitive and http://en.example.org/wiki/URL is correct, then http://en.example.org/WIKI/URL or http://en.example.org/wiki/url will display an HTTP 404 error page, unless these URLs point to valid resources themselves.

Take a look at UnCSS. It helps in creating a CSS file of used CSS.

1- Explanation of Scripts

A)Syntax for inserting data in table is as below

Insert into table(col1,col2,col3,col4,col5)    

             -- To achieve this part i    
             --have used below variable
                ------@CSV_COLUMN-------

values(Col1 data in quote, Col2..quote,..Col5..quote)

-- To achieve this part 
-- i.e column data in 
--quote i have used 
--below variable
----@QUOTED_DATA---

C)To get above data from existing table we have to write the select query in such way that the output will be in form of as above scripts

D)Then Finally i have Concatenated above variable to create final script that's will generate insert script on execution

E)

@TEXT='SELECT ''INSERT INTO
 '+@TABLE_NAME+'('+@CSV_COLUMN+')VALUES('''+'+'+SUBSTRING(@QUOTED_DATA,1,LEN(@QUOTED_DATA)-5)+'+'+''')'''+' Insert_Scripts FROM '+@TABLE_NAME + @FILTER_CONDITION

F)And Finally Executed the above query EXECUTE(TEXT)

G)QUOTENAME() function is used to wrap column data inside quote

H)ISNULL is used because if any row has NULL data for any column the query fails and return NULL thats why to avoid that i have used ISNULL

I)And created the sp sp_generate_insertscripts for same

1- Just put the table name for which you want insert script

2- Filter condition if you want specific results

----------Final Procedure To generate Script------

CREATE PROCEDURE sp_generate_insertscripts
(
    @TABLE_NAME VARCHAR(MAX),
    @FILTER_CONDITION VARCHAR(MAX)=''
)
AS
BEGIN

SET NOCOUNT ON

DECLARE @CSV_COLUMN VARCHAR(MAX),
        @QUOTED_DATA VARCHAR(MAX),
        @TEXT VARCHAR(MAX)

SELECT @CSV_COLUMN=STUFF
(
    (
     SELECT ',['+ NAME +']' FROM sys.all_columns 
     WHERE OBJECT_ID=OBJECT_ID(@TABLE_NAME) AND 
     is_identity!=1 FOR XML PATH('')
    ),1,1,''
)

SELECT @QUOTED_DATA=STUFF
(
    (
     SELECT ' ISNULL(QUOTENAME('+NAME+','+QUOTENAME('''','''''')+'),'+'''NULL'''+')+'','''+'+' FROM sys.all_columns 
     WHERE OBJECT_ID=OBJECT_ID(@TABLE_NAME) AND 
     is_identity!=1 FOR XML PATH('')
    ),1,1,''
)

SELECT @TEXT='SELECT ''INSERT INTO '+@TABLE_NAME+'('+@CSV_COLUMN+')VALUES('''+'+'+SUBSTRING(@QUOTED_DATA,1,LEN(@QUOTED_DATA)-5)+'+'+''')'''+' Insert_Scripts FROM '+@TABLE_NAME + @FILTER_CONDITION

--SELECT @CSV_COLUMN AS CSV_COLUMN,@QUOTED_DATA AS QUOTED_DATA,@TEXT TEXT

EXECUTE (@TEXT)

SET NOCOUNT OFF

END

Yes, use getScript instead of document.write - it will even allow for a callback once the file loads.

You might want to check if TinyMCE is defined, though, before including it (for subsequent calls to 'Add Comment') so the code might look something like this:

$('#add_comment').click(function() {
    if(typeof TinyMCE == "undefined") {
        $.getScript('tinymce.js', function() {
            TinyMCE.init();
        });
    }
});

Assuming you only have to call init on it once, that is. If not, you can figure it out from here :)

A simple solution is to have your factory return an object and let your controllers work with a reference to the same object:

JS:

// declare the app with no dependencies
var myApp = angular.module('myApp', []);

// Create the factory that share the Fact
myApp.factory('Fact', function(){
  return { Field: '' };
});

// Two controllers sharing an object that has a string in it
myApp.controller('FirstCtrl', function( $scope, Fact ){
  $scope.Alpha = Fact;
});

myApp.controller('SecondCtrl', function( $scope, Fact ){
  $scope.Beta = Fact;
});

HTML:

<div ng-controller="FirstCtrl">
    <input type="text" ng-model="Alpha.Field">
    First {{Alpha.Field}}
</div>

<div ng-controller="SecondCtrl">
<input type="text" ng-model="Beta.Field">
    Second {{Beta.Field}}
</div>

Demo: http://jsfiddle.net/HEdJF/

When applications get larger, more complex and harder to test you might not want to expose the entire object from the factory this way, but instead give limited access for example via getters and setters:

myApp.factory('Data', function () {

    var data = {
        FirstName: ''
    };

    return {
        getFirstName: function () {
            return data.FirstName;
        },
        setFirstName: function (firstName) {
            data.FirstName = firstName;
        }
    };
});

With this approach it is up to the consuming controllers to update the factory with new values, and to watch for changes to get them:

myApp.controller('FirstCtrl', function ($scope, Data) {

    $scope.firstName = '';

    $scope.$watch('firstName', function (newValue, oldValue) {
        if (newValue !== oldValue) Data.setFirstName(newValue);
    });
});

myApp.controller('SecondCtrl', function ($scope, Data) {

    $scope.$watch(function () { return Data.getFirstName(); }, function (newValue, oldValue) {
        if (newValue !== oldValue) $scope.firstName = newValue;
    });
});

HTML:

<div ng-controller="FirstCtrl">
  <input type="text" ng-model="firstName">
  <br>Input is : <strong>{{firstName}}</strong>
</div>
<hr>
<div ng-controller="SecondCtrl">
  Input should also be here: {{firstName}}
</div>

As of V8 v7.0 / Chrome 70, V8 uses TimSort, Python's sorting algorithm. Chrome 70 was released on September 13, 2018.

See the the post on the V8 dev blog for details about this change. You can also read the source code or patch 1186801.

You can use MarkerWithLabel with SVG icons.

Update: The Google Maps Javascript API v3 now natively supports multiple characters in the MarkerLabel

Note: there is an issue with labels on overlapping markers that is addressed by this fix, credit to robd who brought it up in the comments.

Please change your javascript function as like below....

$(function () {
        $("#projectKey").change(function () {
            alert($('option:selected').text());
        });
    });

You do not need to use $(this) in alert.

If you're not too worried in accuracy after days, you can simply do the maths

function timeSince(when) { // this ignores months
    var obj = {};
    obj._milliseconds = (new Date()).valueOf() - when.valueOf();
    obj.milliseconds = obj._milliseconds % 1000;
    obj._seconds = (obj._milliseconds - obj.milliseconds) / 1000;
    obj.seconds = obj._seconds % 60;
    obj._minutes = (obj._seconds - obj.seconds) / 60;
    obj.minutes = obj._minutes % 60;
    obj._hours = (obj._minutes - obj.minutes) / 60;
    obj.hours = obj._hours % 24;
    obj._days = (obj._hours - obj.hours) / 24;
    obj.days = obj._days % 365;
    // finally
    obj.years = (obj._days - obj.days) / 365;
    return obj;
}

then timeSince(pastDate); and use the properties as you like.

Otherwise you can use .getUTC* to calculate it, but note it may be slightly slower to calculate

function timeSince(then) {
    var now = new Date(), obj = {};
    obj.milliseconds = now.getUTCMilliseconds() - then.getUTCMilliseconds();
    obj.seconds = now.getUTCSeconds() - then.getUTCSeconds();
    obj.minutes = now.getUTCMinutes() - then.getUTCMinutes();
    obj.hours = now.getUTCHours() - then.getUTCHours();
    obj.days = now.getUTCDate() - then.getUTCDate();
    obj.months = now.getUTCMonth() - then.getUTCMonth();
    obj.years = now.getUTCFullYear() - then.getUTCFullYear();
    // fix negatives
    if (obj.milliseconds < 0) --obj.seconds, obj.milliseconds = (obj.milliseconds + 1000) % 1000;
    if (obj.seconds < 0) --obj.minutes, obj.seconds = (obj.seconds + 60) % 60;
    if (obj.minutes < 0) --obj.hours, obj.minutes = (obj.minutes + 60) % 60;
    if (obj.hours < 0) --obj.days, obj.hours = (obj.hours + 24) % 24;
    if (obj.days < 0) { // months have different lengths
        --obj.months;
        now.setUTCMonth(now.getUTCMonth() + 1);
        now.setUTCDate(0);
        obj.days = (obj.days + now.getUTCDate()) % now.getUTCDate();
    }
    if (obj.months < 0)  --obj.years, obj.months = (obj.months + 12) % 12;
    return obj;
}

Here are the two simple ways I have understood by now and make sure your "file.py" file which you want to import as a library is present in your current directory only.

There is another solution. If you store your color as normal hex string and don't want to add opacity to it (leading FF): 1) Convert your hex string to int To convert a hex-string to an integer, do one of the following:

var myInt = int.parse(hexString, radix: 16);

or

var myInt = int.parse("0x$hexString");

as a prefix of 0x (or -0x) will make int.parse default to radix of 16.

2) Add opacity to your color via code

Color color = new Color(myInt).withOpacity(1.0);

json_decode() will return an object or array if second value it's true:

$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];

I always use READ UNCOMMITTED now. It's fast with the least issues. When using other isolations you will almost always come across some Blocking issues.

As long as you use Auto Increment fields and pay a little more attention to inserts then your fine, and you can say goodbye to blocking issues.

You can make errors with READ UNCOMMITED but to be honest, it is very easy make sure your inserts are full proof. Inserts/Updates which use the results from a select are only thing you need to watch out for. (Use READ COMMITTED here, or ensure that dirty reads aren't going to cause a problem)

So go the Dirty Reads (Specially for big reports), your software will run smoother...

Something that is not relevant for the OP, but maybe for someone else in the future:

For pixels (px), if the value is "0", the unit can be omitted: right: 0 and right: 0px both work.

However I noticed that in Firefox and Chrome this is not the case for the seconds unit (s). While transition: right 1s ease 0s works, transition: right 1s ease 0 (missing unit s for last value transition-delay) does not (it does work in Edge however).

In the following example, you'll see that right works for both 0px and 0, but transition only works for 0s and it doesn't work with 0.

The real solution that I found for this issue was by disabling any XML Format post processors. I have added a post processor called "jp@gc - XML Format Post Processor" and started noticing the error "Fatal Error :1:1: Content is not allowed in prolog"

By disabling the post processor had stopped throwing those errors.

It's been a while since I read it (so, I'm not sure how much of it is still relevant), but my recollection is that Joe Celko's SQL for Smarties book provides a lot of info on writing elegant, effective, and efficient queries.

I got this error message too.

and what makes me think it is useful to give an answer here is that the answer from @Rafal Rawicki is a good solution in some cases but not for all circumstances. example that i met:

1.run "git log" we can get the HEAD commit change-id

2.we also can get a 'HEAD' commit change-id on Gerrit website.

3.they are different ,which makes us can not push successfully and get the "missing change-id error"

solution:

0.'git add .'

1.save your HEAD commit change-id got from 'git log',it will be used later.

2.copy the HEAD commit change-id from Gerrit website.

3.'git reset HEAD'

4.'git commit --amend' and copy the change-id from **Gerrit website** to the commit message in the last paragraph(replace previous change-id)

5.'git push *' you can push successfully now but can not find the HEAD commit from **git log** on Gerrit website too

6.'git reset HEAD'

7.'git commit --amend' and copy the change-id from **git log**(we saved in step 1) to the commit message in the last paragraph(replace previous change-id)

8.'git push *' you can find the HEAD commit from **git log** on Gerrit website,they have the same change-id

9.done

Simpler with the ANY construct:

SELECT value_variable = ANY ('{1,2,3}'::int[])

The right operand of ANY (between parentheses) can either be a set (result of a subquery, for instance) or an array. There are several ways to use it:

• SQLAlchemy: how to filter on PgArray column types?
• IN vs ANY operator in PostgreSQL

Important difference: Array operators (<@, @>, && et al.) expect array types as operands and support GIN or GiST indices in the standard distribution of PostgreSQL, while the ANY construct expects an element type as left operand and does not support these indices. Example:

• Index for finding an element in a JSON array

None of this works for NULL elements. To test for NULL:

• Check if NULL exists in Postgres array

These days it's very easy - right click any item displayed in the console log and select save as and save the whole log output to a file on your computer.

synchronized simple means no two threads can access the block/method simultaneously. When we say any block/method of a class is synchronized it means only one thread can access them at a time. Internally the thread which tries to access it first take a lock on that object and as long as this lock is not available no other thread can access any of the synchronized methods/blocks of that instance of the class.

Note another thread can access a method of the same object which is not defined to be synchronized. A thread can release the lock by calling

Object.wait()

if you are on linux, edit the /etc/php/php.ini (or you will have to create a new extension import file at /etc/php5/cli/conf.d) file so that you add the imap shared object file and then, restart the apache server. Uncomment

;extension=imap.so

so that it becomes like this:

extension=imap.so

Then, restart the apache by

# /etc/rc.d/httpd restart

It seems that you actually haven't executed your query. Try following:

return jsonify(json_list = qryresult.all())

[Edit]: Problem with jsonify is, that usually the objects cannot be jsonified automatically. Even Python's datetime fails ;)

What I have done in the past, is adding an extra property (like serialize) to classes that need to be serialized.

def dump_datetime(value):
    """Deserialize datetime object into string form for JSON processing."""
    if value is None:
        return None
    return [value.strftime("%Y-%m-%d"), value.strftime("%H:%M:%S")]

class Foo(db.Model):
    # ... SQLAlchemy defs here..
    def __init__(self, ...):
       # self.foo = ...
       pass

    @property
    def serialize(self):
       """Return object data in easily serializable format"""
       return {
           'id'         : self.id,
           'modified_at': dump_datetime(self.modified_at),
           # This is an example how to deal with Many2Many relations
           'many2many'  : self.serialize_many2many
       }
    @property
    def serialize_many2many(self):
       """
       Return object's relations in easily serializable format.
       NB! Calls many2many's serialize property.
       """
       return [ item.serialize for item in self.many2many]

And now for views I can just do:

return jsonify(json_list=[i.serialize for i in qryresult.all()])

Hope this helps ;)

[Edit 2019]: In case you have more complex objects or circular references, use a library like marshmallow).

f is an (instance) method. However, you are calling it via fibo.f, where fibo is the class object. Hence, f is unbound (not bound to any class instance).

If you did

a = fibo()
a.f()

then that f is bound (to the instance a).

private static void iterateBetweenDates(Date startDate, Date endDate) {
    Calendar startCalender = Calendar.getInstance();
    startCalender.setTime(startDate);
    Calendar endCalendar = Calendar.getInstance();
    endCalendar.setTime(endDate);

    for(; startCalender.compareTo(endCalendar)<=0;
          startCalender.add(Calendar.DATE, 1)) {
        // write your main logic here
    }

}

You can refer in this line - Difference between ASP.NET Core (.NET Core) and ASP.NET Core (.NET Framework)

Xamarin is not a debate at all. When you want to build mobile (iOS, Android, and Windows Mobile) apps using C#, Xamarin is your only choice.

The .NET Framework supports Windows and Web applications. Today, you can use Windows Forms, WPF, and UWP to build Windows applications in .NET Framework. ASP.NET MVC is used to build Web applications in .NET Framework.

.NET Core is the new open-source and cross-platform framework to build applications for all operating system including Windows, Mac, and Linux. .NET Core supports UWP and ASP.NET Core only. UWP is used to build Windows 10 targets Windows and mobile applications. ASP.NET Core is used to build browser based web applications.

If you are here because of the Liquibase error saying:

Caused By: Precondition Error
...

and you are using

not {
  indexExists()

precondition multiple times, then you are facing an old bug: https://liquibase.jira.com/browse/CORE-1342

We can try to execute an above check using bare sqlCheck(Postgres):

SELECT COUNT(i.relname)
FROM
    pg_class t,
    pg_class i,
    pg_index ix
WHERE
    t.oid = ix.indrelid
    and i.oid = ix.indexrelid
    and t.relkind = 'r'
    and t.relname = 'tableName'
    and i.relname = 'indexName';

where tableName - is an index table name and indexName - is an index name

You can also put below code to the httaccess file as well to allow CORS using htaccess file

    ######################## Handling Options for the CORS

For information purpose, You can also have a look at this article http://www.ipragmatech.com/enable-cors-using-htaccess/ which allow CORS header.

Try the to_date function.

According to your query Select * from [User] U where U.DateCreated = '2014-02-07'

SQL Server is comparing exact date and time i.e (comparing 2014-02-07 12:30:47.220 with 2014-02-07 00:00:00.000 for equality). that's why result of comparison is false

Therefore, While comparing dates you need to consider time also. You can use
Select * from [User] U where U.DateCreated BETWEEN '2014-02-07' AND '2014-02-08'.

See gjvdkamp's answer below; this feature now exists in C#

var @switch = new Dictionary<Type, Action> {
    { typeof(Type1), () => ... },
    { typeof(Type2), () => ... },
    { typeof(Type3), () => ... },
};

@switch[typeof(MyType)]();

It's a little less flexible as you can't fall through cases, continue etc. But I rarely do so anyway.

The code doesn't work because elapsed variable in getElapsedTimeSecs() is not a float or double.

This could be the easiest in my opinion:

SELECT * FROM `table` WHERE `timestamp` like concat(CURDATE(),'%');

If you want to change background color, try this:

plt.rcParams['figure.facecolor'] = 'white'

right click on the pivot table in excel choose wizard click 'back' click 'get data...' in the query window File - Table Definition

then you can create a new or choose a different connection

worked perfectly.

PHP 8 update

PHP 8 includes new str_starts_with and str_ends_with functions that finally provide a performant and convenient solution to this problem:

$str = "beginningMiddleEnd";
if (str_starts_with($str, "beg")) echo "printed\n";
if (str_starts_with($str, "Beg")) echo "not printed\n";
if (str_ends_with($str, "End")) echo "printed\n";
if (str_ends_with($str, "end")) echo "not printed\n";

The RFC for this feature provides more information, and also a discussion of the merits and problems of obvious (and not-so-obvious) userland implementations.

names = [];
$('input[name=text], textarea').each(
    function(index){  
        var input = $(this);
        names.push( input.attr('name') );
        //input.attr('id');
    }
);

it select all textboxes and textarea in your DOM, where $.each function iterates to provide name of ecah element.

You'll have to wait. The session that was killed was in the middle of a transaction and updated lots of records. These records have to be rollbacked and some background process is taking care of that. In the meantime you cannot modify the records that were touched.

try like this

$('title').text();

First, let’s clarify what HEAD is and what it means when it is detached.

HEAD is the symbolic name for the currently checked out commit. When HEAD is not detached (the “normal”¹ situation: you have a branch checked out), HEAD actually points to a branch’s “ref” and the branch points to the commit. HEAD is thus “attached” to a branch. When you make a new commit, the branch that HEAD points to is updated to point to the new commit. HEAD follows automatically since it just points to the branch.

• git symbolic-ref HEAD yields refs/heads/master
  The branch named “master” is checked out.
• git rev-parse refs/heads/master yield 17a02998078923f2d62811326d130de991d1a95a
  That commit is the current tip or “head” of the master branch.
• git rev-parse HEAD also yields 17a02998078923f2d62811326d130de991d1a95a
  This is what it means to be a “symbolic ref”. It points to an object through some other reference.
  (Symbolic refs were originally implemented as symbolic links, but later changed to plain files with extra interpretation so that they could be used on platforms that do not have symlinks.)

We have HEAD ? refs/heads/master ? 17a02998078923f2d62811326d130de991d1a95a

When HEAD is detached, it points directly to a commit—instead of indirectly pointing to one through a branch. You can think of a detached HEAD as being on an unnamed branch.

• git symbolic-ref HEAD fails with fatal: ref HEAD is not a symbolic ref
• git rev-parse HEAD yields 17a02998078923f2d62811326d130de991d1a95a
  Since it is not a symbolic ref, it must point directly to the commit itself.

We have HEAD ? 17a02998078923f2d62811326d130de991d1a95a

The important thing to remember with a detached HEAD is that if the commit it points to is otherwise unreferenced (no other ref can reach it), then it will become “dangling” when you checkout some other commit. Eventually, such dangling commits will be pruned through the garbage collection process (by default, they are kept for at least 2 weeks and may be kept longer by being referenced by HEAD’s reflog).

¹ It is perfectly fine to do “normal” work with a detached HEAD, you just have to keep track of what you are doing to avoid having to fish dropped history out of the reflog.

The intermediate steps of an interactive rebase are done with a detached HEAD (partially to avoid polluting the active branch’s reflog). If you finish the full rebase operation, it will update your original branch with the cumulative result of the rebase operation and reattach HEAD to the original branch. My guess is that you never fully completed the rebase process; this will leave you with a detached HEAD pointing to the commit that was most recently processed by the rebase operation.

To recover from your situation, you should create a branch that points to the commit currently pointed to by your detached HEAD:

git branch temp
git checkout temp

_{(these two commands can be abbreviated as git checkout -b temp)}

This will reattach your HEAD to the new temp branch.

Next, you should compare the current commit (and its history) with the normal branch on which you expected to be working:

git log --graph --decorate --pretty=oneline --abbrev-commit master origin/master temp
git diff master temp
git diff origin/master temp

(You will probably want to experiment with the log options: add -p, leave off --pretty=… to see the whole log message, etc.)

If your new temp branch looks good, you may want to update (e.g.) master to point to it:

git branch -f master temp
git checkout master

_{(these two commands can be abbreviated as git checkout -B master temp)}

You can then delete the temporary branch:

git branch -d temp

Finally, you will probably want to push the reestablished history:

git push origin master

You may need to add --force to the end of this command to push if the remote branch can not be “fast-forwarded” to the new commit (i.e. you dropped, or rewrote some existing commit, or otherwise rewrote some bit of history).

If you were in the middle of a rebase operation you should probably clean it up. You can check whether a rebase was in process by looking for the directory .git/rebase-merge/. You can manually clean up the in-progress rebase by just deleting that directory (e.g. if you no longer remember the purpose and context of the active rebase operation). Usually you would use git rebase --abort, but that does some extra resetting that you probably want to avoid (it moves HEAD back to the original branch and resets it back to the original commit, which will undo some of the work we did above).

FYI, In Rails 4, you can use not syntax:

Article.where.not(title: ['Rails 3', 'Rails 5'])

Generally

static: no need to create object we can directly call using

ClassName.methodname()

Non Static: we need to create a object like

ClassName obj=new ClassName()
obj.methodname();

Let's polyfill:

if(!AbortController){
  class AbortController {
    constructor() {
      this.aborted = false;
      this.signal = this.signal.bind(this);
    }
    signal(abortFn, scope) {
      if (this.aborted) {
        abortFn.apply(scope, { name: 'AbortError' });
        this.aborted = false;
      } else {
        this.abortFn = abortFn.bind(scope);
      }
    }
    abort() {
      if (this.abortFn) {
        this.abortFn({ reason: 'canceled' });
        this.aborted = false;
      } else {
        this.aborted = true;
      }
    }
  }

  const originalFetch = window.fetch;

  const customFetch = (url, options) => {
    const { signal } = options || {};

    return new Promise((resolve, reject) => {
      if (signal) {
        signal(reject, this);
      }
      originalFetch(url, options)
        .then(resolve)
        .catch(reject);
    });
  };

  window.fetch = customFetch;
}

Please have in mind that the code is not tested! Let me know if you have tested it and something didn't work. It may give you warnings that you try to overwrite the 'fetch' function from the JavaScript official library.

Stopping the thread in midway using Thread.stop() is not a good practice. More appropriate way is to make the thread return programmatically. Let the Runnable object use a shared variable in the run() method. Whenever you want the thread to stop, use that variable as a flag.

EDIT: Sample code

class MyThread implements Runnable{
    
    private Boolean stop = false;
    
    public void run(){
        
        while(!stop){
            
            //some business logic
        }
    }
    public Boolean getStop() {
        return stop;
    }

    public void setStop(Boolean stop) {
        this.stop = stop;
    }       
}

public class TestStop {
    
    public static void main(String[] args){
        
        MyThread myThread = new MyThread();
        Thread th = new Thread(myThread);
        th.start();
        
        //Some logic goes there to decide whether to 
        //stop the thread or not. 
        
        //This will compell the thread to stop
        myThread.setStop(true);
    }
}

If you need to mock a static method, it is a strong indicator for a bad design. Usually, you mock the dependency of your class-under-test. If your class-under-test refers to a static method - like java.util.Math#sin for example - it means the class-under-test needs exactly this implementation (of accuracy vs. speed for example). If you want to abstract from a concrete sinus implementation you probably need an Interface (you see where this is going to)?

try this. There are in general three ways to use mysqldump—

in order to dump a set of one or more tables,

shell> mysqldump [options] db_name [tbl_name ...]

a set of one or more complete databases

shell> mysqldump [options] --databases db_name ...

or an entire MySQL server—as shown here:

shell> mysqldump [options] --all-databases

There are a couple options you can use:

1. You could try using the string "(DATETIME('now'))" instead.
2. Insert the datetime yourself, ie with System.currentTimeMillis()
3. When creating the SQLite table, specify a default value for the created_date column as the current date time.
4. Use SQLiteDatabase.execSQL to insert directly.

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

1. Go to the official website and download the source code for the version you need

2. Then unzip the update package and execute the following command

   ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl  -Wl,-rpath,/usr/local/ssl/lib shared
   

Because the default is to generate only static libraries, if you want dynamic libraries, add the "shared" option

3. make && make install

Cross origin protection is a feature of the browser. Curl does not care for CORS, as you presumed. That explains why your curls are successful, while the browser requests are not.

If you send the browser request with the wrong credentials, spring will try to forward the client to a login page. This response (off the login page) does not contain the header 'Access-Control-Allow-Origin' and the browser reacts as you describe.

You must make spring to include the haeder for this login response, and may be for other response, like error pages etc.

This can be done like this :

    @Configuration
    @EnableWebMvc
    public class WebConfig extends WebMvcConfigurerAdapter {

            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/api/**")
                    .allowedOrigins("http://domain2.com")
                    .allowedMethods("PUT", "DELETE")
                    .allowedHeaders("header1", "header2", "header3")
                    .exposedHeaders("header1", "header2")
                    .allowCredentials(false).maxAge(3600);
            }
     }

This is copied from cors-support-in-spring-framework

I would start by adding cors mapping for all resources with :

registry.addMapping("/**")

and also allowing all methods headers.. Once it works you may start to reduce that again to the needed minimum.

Please note, that the CORS configuration changes with Release 4.2.

If this does not solve your issues, post the response you get from the failed ajax request.

Well this certainly won't be an answer like Matt J's but hopefully it will still be useful.

size_t reverse(size_t n, unsigned int bytes)
{
    __asm__("BSWAP %0" : "=r"(n) : "0"(n));
    n >>= ((sizeof(size_t) - bytes) * 8);
    n = ((n & 0xaaaaaaaaaaaaaaaa) >> 1) | ((n & 0x5555555555555555) << 1);
    n = ((n & 0xcccccccccccccccc) >> 2) | ((n & 0x3333333333333333) << 2);
    n = ((n & 0xf0f0f0f0f0f0f0f0) >> 4) | ((n & 0x0f0f0f0f0f0f0f0f) << 4);
    return n;
}

This is exactly the same idea as Matt's best algorithm except that there's this little instruction called BSWAP which swaps the bytes (not the bits) of a 64-bit number. So b7,b6,b5,b4,b3,b2,b1,b0 becomes b0,b1,b2,b3,b4,b5,b6,b7. Since we are working with a 32-bit number we need to shift our byte-swapped number down 32 bits. This just leaves us with the task of swapping the 8 bits of each byte which is done and voila! we're done.

Timing: on my machine, Matt's algorithm ran in ~0.52 seconds per trial. Mine ran in about 0.42 seconds per trial. 20% faster is not bad I think.

If you're worried about the availability of the instruction BSWAP Wikipedia lists the instruction BSWAP as being added with 80846 which came out in 1989. It should be noted that Wikipedia also states that this instruction only works on 32 bit registers which is clearly not the case on my machine, it very much works only on 64-bit registers.

This method will work equally well for any integral datatype so the method can be generalized trivially by passing the number of bytes desired:

    size_t reverse(size_t n, unsigned int bytes)
    {
        __asm__("BSWAP %0" : "=r"(n) : "0"(n));
        n >>= ((sizeof(size_t) - bytes) * 8);
        n = ((n & 0xaaaaaaaaaaaaaaaa) >> 1) | ((n & 0x5555555555555555) << 1);
        n = ((n & 0xcccccccccccccccc) >> 2) | ((n & 0x3333333333333333) << 2);
        n = ((n & 0xf0f0f0f0f0f0f0f0) >> 4) | ((n & 0x0f0f0f0f0f0f0f0f) << 4);
        return n;
    }

which can then be called like:

    n = reverse(n, sizeof(char));//only reverse 8 bits
    n = reverse(n, sizeof(short));//reverse 16 bits
    n = reverse(n, sizeof(int));//reverse 32 bits
    n = reverse(n, sizeof(size_t));//reverse 64 bits

The compiler should be able to optimize the extra parameter away (assuming the compiler inlines the function) and for the sizeof(size_t) case the right-shift would be removed completely. Note that GCC at least is not able to remove the BSWAP and right-shift if passed sizeof(char).

all above answers is correct but however

a = [];
len(list1) - 1 # where 0 - 1 = -1

to be more precisely

a = [];
index = len(a) - 1 if a else None;

if index == None : raise Exception("Empty Array")

since arrays is starting with 0

Here's what I use at the top of all my batch files. I just copy/paste from my template folder.

@echo off
:: --HAS ENDING BACKSLASH
set batdir=%~dp0
:: --MISSING ENDING BACKSLASH
:: set batdir=%CD%
pushd "%batdir%"

Setting current batch file's path to %batdir% allows you to call it in subsequent stmts in current batch file, regardless of where this batch file changes to. Using PUSHD allows you to use POPD to quickly set this batch file's path to original %batdir%. Remember, if using %batdir%ExtraDir or %batdir%\ExtraDir (depending on which version used above, ending backslash or not) you will need to enclose the entire string in double quotes if path has spaces (i.e. "%batdir%ExtraDir"). You can always use PUSHD %~dp0. [https: // ss64.com/ nt/ syntax-args .html] has more on (%~) parameters.

Note that using (::) at beginning of a line makes it a comment line. More importantly, using :: allows you to include redirectors, pipes, special chars (i.e. < > | etc) in that comment.

:: ORIG STMT WAS: dir *.* | find /v "1917" > outfile.txt

Of course, Powershell does this and lots more.

You define a DELIMITER to tell the mysql client to treat the statements, functions, stored procedures or triggers as an entire statement. Normally in a .sql file you set a different DELIMITER like $$. The DELIMITER command is used to change the standard delimiter of MySQL commands (i.e. ;). As the statements within the routines (functions, stored procedures or triggers) end with a semi-colon (;), to treat them as a compound statement we use DELIMITER. If not defined when using different routines in the same file or command line, it will give syntax error.

Note that you can use a variety of non-reserved characters to make your own custom delimiter. You should avoid the use of the backslash (\) character because that is the escape character for MySQL.

DELIMITER isn't really a MySQL language command, it's a client command.

Example

DELIMITER $$

/*This is treated as a single statement as it ends with $$ */
DROP PROCEDURE IF EXISTS `get_count_for_department`$$

/*This routine is a compound statement. It ends with $$ to let the mysql client know to execute it as a single statement.*/ 
CREATE DEFINER=`student`@`localhost` PROCEDURE `get_count_for_department`(IN the_department VARCHAR(64), OUT the_count INT)
BEGIN
    
    SELECT COUNT(*) INTO the_count FROM employees where department=the_department;

END$$

/*DELIMITER is set to it's default*/
DELIMITER ;

It's a terrible practice to give away access to the entire s3 (all actions, all buckets), just to unblock yourself.

The 403 error above is usually due to the lack of "Read" permission of files. The Read action for reading a file in S3 is s3:GetObject.

        {
            "Effect": "Allow",
            "Action": "s3:GetObject",
            "Resource": [
                "arn:aws:s3:::mybucketname/path/*",
                "arn:aws:s3:::mybucketname"
            ]
        }

Solution 1: A new Policy in IAM (Tell Role/User to know S3)

You can create a Policy (e.g. MY_S3_READER) with the following, and attach it to the user or role that's doing the job. (e.g. EC2 Instance's IAM role)

Here is the exact JSON for your Policy: (just replace mybucketname and path)

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "s3:GetObject",
            "Resource": [
                "arn:aws:s3:::mybucketname/path/*",
                "arn:aws:s3:::mybucketname"
            ]
        }
    ]
}

Create this Policy. Then, go to IAM > Roles > Attach Policy and attach it.

Solution 2: Edit Buckey Policy in S3 (Tell S3 to know User/Role)

Go to your bucket in S3, then add the following example: (replace mybucketname and myip)

{
    "Version": "2012-10-17",
    "Id": "SourceIP",
    "Statement": [
        {
            "Sid": "ValidIpAllowRead",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": [
                "arn:aws:s3:::mybucketname",
                "arn:aws:s3:::mybucketname/*"
            ],
            "Condition": {
                "IpAddress": {
                    "aws:SourceIp": "myip/32"
                }
            }
        }
    ]
}

If you want to change this read permission to by User or Role (instead of IP Address), remove the Condition part, and change "Principal" to "Principal": { "AWS": "<IAM User/Role's ARN>" },".

Additional Notes

1. Check the permissions via aws s3 cp or aws s3 ls manually for faster debugging.

2. It sometimes takes up to 30 seconds for the permission change to be effective. Be patient.

3. Note that for doing "ls" (e.g. aws s3 ls s3://mybucket/mypath) you need s3:ListBucket access.

4. IMPORTANT Accessing files by their HTTP(S) URL via cURL or similar tools (e.g. axios on AJAX calls) requires you to grant either IP access, or supply proper headers, manually, or get a signedUrl from the SDK first.

Our js-programmer asked me to return the exact JSON format data instead of a json-encoded string to her.

Below is the solution.(This will return an object that can be used/viewed straightly in the browser)

import json
from xxx.models import alert
from django.core import serializers

def test(request):
    alert_list = alert.objects.all()

    tmpJson = serializers.serialize("json",alert_list)
    tmpObj = json.loads(tmpJson)

    return HttpResponse(json.dumps(tmpObj))

JavaScript doesn't have associate arrays. You need to use Objects instead:

var obj = {};
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);?

To get value you can use now different ways:

console.log(obj.name);?
console.log(obj[name]);?
console.log(obj["name"]);?

Try this:

@Html.TextbBoxFor(x=>x.Email,new { @[email protected]}

If this possible or else what could be the way

You need to start the script with a preceding dot, this will put the exported variables in the current environment.

#!/bin/bash
...
export output="SUCCESS"

Then execute it like so

chmod +x /tmp/test.sh
. /tmp/test.sh

When you need the entire output and not just a single value, just put the output in a variable like the other answers indicate

I spent the entire morning solving a similar problem after having landed on this stack question. I used Dan's first solution in the answer above as the jump off point.

Problem

I have a dev (this is on my local machine), staging, and production environment. My staging and production environments live on the same server.

The app is deployed to staging via acmeserver/~staging/note-taking-app and the production version lives at acmeserver/note-taking-app (blame IT).

All the media files such as fonts were loading perfectly fine on dev (i.e., react-scripts start).

However, when I created and uploaded staging and production builds, while the .css and .js files were loading properly, fonts were not. The compiled .css file looked to have a correct path but the browser http request was getting some very wrong pathing (shown below).

The compiled main.fc70b10f.chunk.css file:

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf) ("truetype");
}

The browser http request is shown below. Note how it is adding in /static/css/ when the font file just lives in /static/media/ as well as duplicating the destination folder. I ruled out the server config being the culprit.

The Referer is partly at fault too.

GET /~staging/note-taking-app/static/css/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf HTTP/1.1
Host: acmeserver
Origin: http://acmeserver
Referer: http://acmeserver/~staging/note-taking-app/static/css/main.fc70b10f.chunk.css

The package.json file had the homepage property set to ./note-taking-app. This was causing the problem.

{
  "name": "note-taking-app",
  "version": "0.1.0",
  "private": true,
  "homepage": "./note-taking-app",
  "scripts": {
    "start": "env-cmd -e development react-scripts start",
    "build": "react-scripts build",
    "build:staging": "env-cmd -e staging npm run build",
    "build:production": "env-cmd -e production npm run build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }
  //...
}

Solution

That was long winded — but the solution is to:

1. change the PUBLIC_URL env variable depending on the environment
2. remove the homepage property from the package.json file

Below is my .env-cmdrc file. I use .env-cmdrc over regular .env because it keeps everything together in one file.

{
  "development": {
    "PUBLIC_URL": "",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "staging": {
    "PUBLIC_URL": "/~staging/note-taking-app",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "production": {
    "PUBLIC_URL": "/note-taking-app",
    "REACT_APP_API": "http://acmeserver/note-taking-app/api"
  }
}

Routing via react-router-dom works fine too — simply use the PUBLIC_URL env variable as the basename property.

import React from "react";
import { BrowserRouter } from "react-router-dom";

const createRouter = RootComponent => (
  <BrowserRouter basename={process.env.PUBLIC_URL}>
    <RootComponent />
  </BrowserRouter>
);

export { createRouter };

The server config is set to route all requests to the ./index.html file.

Finally, here is what the compiled main.fc70b10f.chunk.css file looks like after the discussed changes were implemented.

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(/~staging/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf)
    format("truetype");
}

    Create React App assumes your application is hosted at the serving web server's root or a subpath as specified in package.json (homepage). Normally, Create React App ignores the hostname. You may use this variable to force assets to be referenced verbatim to the url you provide (hostname included). This may be particularly useful when using a CDN to host your application.

Or if you have an array of [key, value] arrays, you can do:

[[1, 2], [3, 4]].inject({}) do |r, s|
  r.merge!({s[0] => s[1]})
end # => { 1 => 2, 3 => 4 }

Undo multiple commits git reset --hard 0ad5a7a6 (Just provide commit SHA1 hash)

Undo last commit

git reset --hard HEAD~1 (changes to last commit will be removed ) git reset --soft HEAD~1 (changes to last commit will be available as uncommited local modifications)

If you want to install/upgrade all packages to the latest version and you are running windows you can use this in powershell.exe:

foreach($package in @("animations","common","compiler","core","forms","http","platform-browser","platform-browser-dynamic","router")) {
    npm install @angular/$package@latest -E
}

If you also use the cli, you can do this:

foreach($package in @('animations','common','compiler','core','forms','http','platform-browser','platform-browser-dynamic','router', 'cli','compiler-cli')){
    iex "npm install @angular/$package@latest -E $(If($('cli','compiler-cli').Contains($package)){'-D'})";
}

This will save the packages exact (-E), and the cli packages in devDependencies (-D)

Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.

To create a new branch with a copy of your current state

git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server

Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.

According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource, as per this line:

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource class in it.

You may use the package I have published: https://github.com/sineld/bladeset

Then you easily set your variable:

@set('myVariable', $existing_variable)

// or

@set("myVariable", "Hello, World!")

In the terminal, use "mongo" command to switch the terminal into the MongoDB shell:

$ mongo
MongoDB shell version: 2.6.10
connecting to: admin

Once you get > symbol in the terminal, you have entered into the MongoDB shell.

For anyone meaning to do this more reliably for different Minecraft versions, I have a Python script (adapted from parts of minecraft-launcher-lib) that does the job very nicely

Besides setting some basic variables near the top after the functions, it calls a get_classpath that goes through for example ~/.minecraft/versions/1.16.5/1.16.5.json, and loops over the libraries array, checking to see if each object (within the array), is supposed to be added to the classpath (cp variable). whether this library is added to the java classpath is governed by the should_use_library function, deterministic based on the computer's architecture and operating system. finally, some jarfiles that are platform specific have extra things prepended to them (ex. natives-linux in org/lwjgl/lwjgl/3.2.1/lwjgl-3.2.1-natives-linux.jar). this extra prepended string is handled by get_natives_string and is empty if it doesn't apply to the current library

"Deceptively simple task." – Potatoswatter

Indeed. There's many little devils hanging out in the details of this problem. It was very fun to solve tho.

EDIT: This update takes a much more compositional approach. Previously there was one big function which wrapped a couple other proprietary functions. Instead, this time we define generic reusable functions which could be used for many varieties of tasks. More about those after we take a look at numToWords itself …

// numToWords :: (Number a, String a) => a -> String
let numToWords = n => {
  let a = [
    '', 'one', 'two', 'three', 'four',
    'five', 'six', 'seven', 'eight', 'nine',
    'ten', 'eleven', 'twelve', 'thirteen', 'fourteen',
    'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen'
  ];
  let b = [
    '', '', 'twenty', 'thirty', 'forty',
    'fifty', 'sixty', 'seventy', 'eighty', 'ninety'
  ];
  let g = [
    '', 'thousand', 'million', 'billion', 'trillion', 'quadrillion',
    'quintillion', 'sextillion', 'septillion', 'octillion', 'nonillion'
  ];
  // this part is really nasty still
  // it might edit this again later to show how Monoids could fix this up
  let makeGroup = ([ones,tens,huns]) => {
    return [
      num(huns) === 0 ? '' : a[huns] + ' hundred ',
      num(ones) === 0 ? b[tens] : b[tens] && b[tens] + '-' || '',
      a[tens+ones] || a[ones]
    ].join('');
  };
  // "thousands" constructor; no real good names for this, i guess
  let thousand = (group,i) => group === '' ? group : `${group} ${g[i]}`;
  // execute !
  if (typeof n === 'number') return numToWords(String(n));
  if (n === '0')             return 'zero';
  return comp (chunk(3)) (reverse) (arr(n))
    .map(makeGroup)
    .map(thousand)
    .filter(comp(not)(isEmpty))
    .reverse()
    .join(' ');
};

Here are the dependencies:

You'll notice these require next to no documentation because their intents are immediately clear. chunk might be the only one that takes a moment to digest, but it's really not too bad. Plus the function name gives us a pretty good indication what it does, and it's probably a function we've encountered before.

const arr = x => Array.from(x);
const num = x => Number(x) || 0;
const str = x => String(x);
const isEmpty = xs => xs.length === 0;
const take = n => xs => xs.slice(0,n);
const drop = n => xs => xs.slice(n);
const reverse = xs => xs.slice(0).reverse();
const comp = f => g => x => f (g (x));
const not = x => !x;
const chunk = n => xs =>
  isEmpty(xs) ? [] : [take(n)(xs), ...chunk (n) (drop (n) (xs))];

"So these make it better?"

Look at how the code has cleaned up significantly

// NEW CODE (truncated)
return comp (chunk(3)) (reverse) (arr(n))
    .map(makeGroup)
    .map(thousand)
    .filter(comp(not)(isEmpty))
    .reverse()
    .join(' ');

// OLD CODE (truncated)
let grp = n => ('000' + n).substr(-3);
let rem = n => n.substr(0, n.length - 3);
let cons = xs => x => g => x ? [x, g && ' ' + g || '', ' ', xs].join('') : xs;
let iter = str => i => x => r => {
  if (x === '000' && r.length === 0) return str;
  return iter(cons(str)(fmt(x))(g[i]))
             (i+1)
             (grp(r))
             (rem(r));
};
return iter('')(0)(grp(String(n)))(rem(String(n)));

Most importantly, the utility functions we added in the new code can be used other places in your app. This means that, as a side effect of implementing numToWords in this way, we get the other functions for free. Bonus soda !

Some tests

console.log(numToWords(11009));
//=> eleven thousand nine

console.log(numToWords(10000001));
//=> ten million one 

console.log(numToWords(987));
//=> nine hundred eighty-seven

console.log(numToWords(1015));
//=> one thousand fifteen

console.log(numToWords(55111222333));
//=> fifty-five billion one hundred eleven million two hundred 
//   twenty-two thousand three hundred thirty-three

console.log(numToWords("999999999999999999999991"));
//=> nine hundred ninety-nine sextillion nine hundred ninety-nine
//   quintillion nine hundred ninety-nine quadrillion nine hundred
//   ninety-nine trillion nine hundred ninety-nine billion nine
//   hundred ninety-nine million nine hundred ninety-nine thousand
//   nine hundred ninety-one

console.log(numToWords(6000753512));
//=> six billion seven hundred fifty-three thousand five hundred
//   twelve

Another option is the janitor package:

df <- remove_empty_cols(df)

https://github.com/sfirke/janitor

The way I've done this is as follows...

condition = True
while condition:
     do_stuff()
     condition = (<something that evaluates to True or False>)

This seems to me to be the simplistic solution, I'm surprised I haven't seen it here already. This can obviously also be inverted to

while not condition:

etc.

I came across this thread when also trying to obtain the return value of a method that gets executed within a Thread. I thought I would post my solution that works.

This solution uses an class to store both the method to be executed (indirectly) and stores the returning value. The class can be used for any function and any return type. You just instantiate the object using the return value type and then pass the function to call via a lambda (or delegate).

C# 3.0 Implementation

public class ThreadedMethod<T>
{

    private T mResult;
    public T Result 
    {
        get { return mResult; }
        private set { mResult = value; }
    }

    public ThreadedMethod()
    {
    }

    //If supporting .net 3.5
    public void ExecuteMethod(Func<T> func)
    {
        Result = func.Invoke();
    }

    //If supporting only 2.0 use this and 
    //comment out the other overload
    public void ExecuteMethod(Delegate d)
    {
        Result = (T)d.DynamicInvoke();
    }
}

To use this code you can use a Lambda (or a delegate). Here is the example using lambdas:

ThreadedMethod<bool> threadedMethod = new ThreadedMethod<bool>();
Thread workerThread = new Thread((unused) => 
                            threadedMethod.ExecuteMethod(() => 
                                SomeMethod()));
workerThread.Start();
workerThread.Join();
if (threadedMethod.Result == false) 
{
    //do something about it...
}

VB.NET 2008 Implementation

Anyone using VB.NET 2008 can't use lambdas with non-value returning methods. This affects the ThreadedMethod class, so we'll make ExecuteMethod return the value of the function. This doesn't hurt anything.

Public Class ThreadedMethod(Of T)

    Private mResult As T
    Public Property Result() As T
        Get
            Return mResult
        End Get
        Private Set(ByVal value As T)
            mResult = value
        End Set
    End Property

    Sub New()
    End Sub

    'If supporting .net 3.5'
    Function ExecuteMethod(ByVal func As Func(Of T)) As T
        Result = func.Invoke()
        Return Result
    End Function

    'If supporting only 2.0 use this and' 
    'comment out the other overload'
    Function ExecuteMethod(ByVal d As [Delegate]) As T
        Result = DirectCast(d.DynamicInvoke(), T)
        Return Result
    End Function

End Class

From a user experience stand-point, you don't want a major action to be done passively.

Something major like a window close should be the result of an action by the user.

We can use Array.sort method to sort this array.

ES5 solution

var array = ["ab", "abcdefgh", "abcd"];

array.sort(function(a, b){return b.length - a.length});

console.log(JSON.stringify(array, null, '\t'));

For ascending sort order: a.length - b.length

For descending sort order: b.length - a.length

ES6 solution

Attention: not all browsers can understand ES6 code!

In ES6 we can use an arrow function expressions.

let array = ["ab", "abcdefgh", "abcd"];

array.sort((a, b) => b.length - a.length);

console.log(JSON.stringify(array, null, '\t'));

I am using Bootstrap v3.3.4 and using the code:

 $('.datepicker').datepicker({
    dateFormat: 'dd-mm-yy'
 });

Output is: 16-07-2015

Note: only need "yy" for full year.

I had this same problem and it turns out I had a '\' instead of a '/' in the xml tag. It still gave the same error but just due to a syntax problem.

If you want to do something like the following example, you'd have to use nested ifs.

If percentage is greater than or equal to 93%, then corresponding value in B should be 4 and if the percentage is greater than or equal to 90% and less than 92%, then corresponding value in B to be 3.7, etc.

Here's how you'd do it:

=IF(A2>=93%, 4, IF(A2>=90%, 3.7,IF(A2>=87%,3.3,0)))

The split() method in javascript accepts two parameters: a separator and a limit. The separator specifies the character to use for splitting the string. If you don't specify a separator, the entire string is returned, non-separated. But, if you specify the empty string as a separator, the string is split between each character.

Therefore:

s.split('')

will have the effect you seek.

SELECT * 
FROM t1
JOIN t2 USING (id, date)

perhaps you'll need to use INNEER JOIN or where t2.id is not null if you want results only matching both conditions

I faced the same problem,but after hours of efforts i find the solution.It can be without using any external plugin:)

applicantListToExport: function (query, callback) {
  this
   .find(query).select({'advtId': 0})
   .populate({
      path: 'influId',
      model: 'influencer',
      select: { '_id': 1,'user':1},
      populate: {
        path: 'userid',
        model: 'User'
      }
   })
 .populate('campaignId',{'campaignTitle':1})
 .exec(callback);
}

According to RFC2965 3.3.1 (which might or might not be followed by browsers), unless the port is explicitly specified via the port parameter of the Set-Cookie header, cookies might or might not be sent to any port.

Google's Browser Security Handbook says: by default, cookie scope is limited to all URLs on the current host name - and not bound to port or protocol information. and some lines later There is no way to limit cookies to a single DNS name only [...] likewise, there is no way to limit them to a specific port. (Also, keep in mind, that IE does not factor port numbers into its same-origin policy at all.)

So it does not seem to be safe to rely on any well-defined behavior here.

To initialize long you need to append "L" to the end.
It can be either uppercase or lowercase.

All the numeric values are by default int. Even when you do any operation of byte with any integer, byte is first promoted to int and then any operations are performed.

Try this

byte a = 1; // declare a byte
a = a*2; //  you will get error here

You get error because 2 is by default int.
Hence you are trying to multiply byte with int. Hence result gets typecasted to int which can't be assigned back to byte.

The solution from PSL will not work in Firefox. FF accepts event only as a formal parameter. So you have to find another way to identify the selected row. My solution is something like this:

...
$('#mySelector')
  .on('show.bs.modal', function(e) {
  var mid;


  if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1) 
    mid = $(e.relatedTarget).data('id');
  else
    mid = $(event.target).closest('tr').data('id');

sys.executable contains full path of the currently running Python interpreter.

You can use OLEDB to create and manipulate Excel files. See this question for links and samples.

Simply:

SELECT COUNT(*) FROM `tablename`

Thought I knew I had read about that in the standard; but can't find it. Keeps looking. Old; answering heading; not Q-tex ;P:

The following program would determine that:

#include <stdio.h>
#include <stdint.h>

int is_big_endian(void)
{
    union {
        uint32_t i;
        char c[4];
    } e = { 0x01000000 };

    return e.c[0];
}

int main(void)
{
    printf("System is %s-endian.\n",
        is_big_endian() ? "big" : "little");

    return 0;
}

You also have this approach; from Quake II:

byte    swaptest[2] = {1,0};
if ( *(short *)swaptest == 1) {
    bigendien = false;

And !is_big_endian() is not 100% to be little as it can be mixed/middle.

Believe this can be checked using same approach only change value from 0x01000000 to i.e. 0x01020304 giving:

switch(e.c[0]) {
case 0x01: BIG
case 0x02: MIX
default: LITTLE

But not entirely sure about that one ...

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

If you are referring to the npm module sleep, it notes in the readme that sleep will block execution. So you are right - it isn't what you want. Instead you want to use setTimeout which is non-blocking. Here is an example:

setTimeout(function() {
  console.log('hello world!');
}, 5000);

For anyone looking to do this using es7 async/await, this example should help:

const snooze = ms => new Promise(resolve => setTimeout(resolve, ms));

const example = async () => {
  console.log('About to snooze without halting the event loop...');
  await snooze(1000);
  console.log('done!');
};

example();

The wait() and notify() methods are designed to provide a mechanism to allow a thread to block until a specific condition is met. For this I assume you're wanting to write a blocking queue implementation, where you have some fixed size backing-store of elements.

The first thing you have to do is to identify the conditions that you want the methods to wait for. In this case, you will want the put() method to block until there is free space in the store, and you will want the take() method to block until there is some element to return.

public class BlockingQueue<T> {

    private Queue<T> queue = new LinkedList<T>();
    private int capacity;

    public BlockingQueue(int capacity) {
        this.capacity = capacity;
    }

    public synchronized void put(T element) throws InterruptedException {
        while(queue.size() == capacity) {
            wait();
        }

        queue.add(element);
        notify(); // notifyAll() for multiple producer/consumer threads
    }

    public synchronized T take() throws InterruptedException {
        while(queue.isEmpty()) {
            wait();
        }

        T item = queue.remove();
        notify(); // notifyAll() for multiple producer/consumer threads
        return item;
    }
}

There are a few things to note about the way in which you must use the wait and notify mechanisms.

Firstly, you need to ensure that any calls to wait() or notify() are within a synchronized region of code (with the wait() and notify() calls being synchronized on the same object). The reason for this (other than the standard thread safety concerns) is due to something known as a missed signal.

An example of this, is that a thread may call put() when the queue happens to be full, it then checks the condition, sees that the queue is full, however before it can block another thread is scheduled. This second thread then take()'s an element from the queue, and notifies the waiting threads that the queue is no longer full. Because the first thread has already checked the condition however, it will simply call wait() after being re-scheduled, even though it could make progress.

By synchronizing on a shared object, you can ensure that this problem does not occur, as the second thread's take() call will not be able to make progress until the first thread has actually blocked.

Secondly, you need to put the condition you are checking in a while loop, rather than an if statement, due to a problem known as spurious wake-ups. This is where a waiting thread can sometimes be re-activated without notify() being called. Putting this check in a while loop will ensure that if a spurious wake-up occurs, the condition will be re-checked, and the thread will call wait() again.

As some of the other answers have mentioned, Java 1.5 introduced a new concurrency library (in the java.util.concurrent package) which was designed to provide a higher level abstraction over the wait/notify mechanism. Using these new features, you could rewrite the original example like so:

public class BlockingQueue<T> {

    private Queue<T> queue = new LinkedList<T>();
    private int capacity;
    private Lock lock = new ReentrantLock();
    private Condition notFull = lock.newCondition();
    private Condition notEmpty = lock.newCondition();

    public BlockingQueue(int capacity) {
        this.capacity = capacity;
    }

    public void put(T element) throws InterruptedException {
        lock.lock();
        try {
            while(queue.size() == capacity) {
                notFull.await();
            }

            queue.add(element);
            notEmpty.signal();
        } finally {
            lock.unlock();
        }
    }

    public T take() throws InterruptedException {
        lock.lock();
        try {
            while(queue.isEmpty()) {
                notEmpty.await();
            }

            T item = queue.remove();
            notFull.signal();
            return item;
        } finally {
            lock.unlock();
        }
    }
}

Of course if you actually need a blocking queue, then you should use an implementation of the BlockingQueue interface.

Also, for stuff like this I'd highly recommend Java Concurrency in Practice, as it covers everything you could want to know about concurrency related problems and solutions.

You have to put a g at the end, it stands for "global":

echo dog dog dos | sed -r 's:dog:log:g'
                                     ^

"Windows could not start the Apache Tomcat 6 on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 0"

When an error of this sort come. please go to start -> configure tomcat -> startup -> Mode -> java similarly start -> configure tomcat -> shutdown -> Mode -> java

Simulator doesn't have a Camera. If you want to access a camera you need a device. You can't test camera on simulator. You can only check the photo and video gallery.

Worked here too:

Sub test544()

  Dim chromePath As String

  chromePath = """C:\Program Files\Google\Chrome\Application\chrome.exe"""

  Shell (chromePath & " -url http:google.ca")

End Sub

I think your error was in calling the function.

In your HTML code, onclick is calling the image() function. However, in your script the function is named imgWindow(). Try changing the onclick to imgWindow().

I don't do much JavaScript so if I have missed something, please let me know.

Good Luck!

This problem mainly happens when you are using connection pooling because when you close connection that connection go back to the connection pool and all cursor associated with that connection never get closed as the connection to database is still open. So one alternative is to decrease the idle connection time of connections in pool, so may whenever connection sits idle in connection for say 10 sec , connection to database will get closed and new connection created to put in pool.

I find the solution is the same as @spyar provide which is the Keychain Access app stored the old username.

There are 2 solutions for this situation:

1. Delete the info in Keychain Access by
   • Open Keychain Access app
   • Search for github
   • Delete corresponding credentials

Or

2. If you use want to use ssh key. You just change your Repo url from https

https://github.com/username/repo.git

into

[email protected]:username/repo.git

Hope this helps.

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

Open Vim, and in normal mode type:

:echo $VIM

Within a constructor, you can use the this keyword to invoke another constructor in the same class. Doing so is called an explicit constructor invocation.

Here's another Rectangle class, with a different implementation from the one in the Objects section.

public class Rectangle {
    private int x, y;
    private int width, height;

    public Rectangle() {
        this(1, 1);
    }
    public Rectangle(int width, int height) {
        this( 0,0,width, height);
    }
    public Rectangle(int x, int y, int width, int height) {
        this.x = x;
        this.y = y;
        this.width = width;
        this.height = height;
    }

}

This class contains a set of constructors. Each constructor initializes some or all of the rectangle's member variables.

Here is the best solution for this. (ANGULAR All Version)

Addressing solution: To set a default value for @Input variable. If no value passed to that input variable then It will take the default value.

I have provided solution for this kind of similar question. You can find the full solution from here

export class CarComponent implements OnInit {
  private _defaultCar: car = {
    // default isCar is true
    isCar: true,
    // default wheels  will be 4
    wheels: 4
  };

  @Input() newCar: car = {};

  constructor() {}

  ngOnInit(): void {

   // this will concate both the objects and the object declared later (ie.. ...this.newCar )
   // will overwrite the default value. ONLY AND ONLY IF DEFAULT VALUE IS PRESENT

    this.newCar = { ...this._defaultCar, ...this.newCar };
   //  console.log(this.newCar);
  }
}

if you run in Jenkins, you can use GIT_BRANCH variable as appears here: https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin

The git plugin sets several environment variables you can use in your scripts:

GIT_COMMIT - SHA of the current

GIT_BRANCH - Name of the branch currently being used, e.g. "master" or "origin/foo"

GIT_PREVIOUS_COMMIT - SHA of the previous built commit from the same branch (the current SHA on first build in branch)

GIT_URL - Repository remote URL

GIT_URL_N - Repository remote URLs when there are more than 1 remotes, e.g. GIT_URL_1, GIT_URL_2

GIT_AUTHOR_EMAIL - Committer/Author Email

GIT_COMMITTER_EMAIL - Committer/Author Email

first you have to give echo to display base url. Then change below value in your autoload.php which will be inside your application/config/ folder. $autoload['helper'] = array('url'); then your issue will be resolved.

also if you want to set the label font in all views in your project try this in appDelegate>didFinishLaunch: UILabel.appearance().font = UIFont("your font name", size: 15)

Oh my God. not need to do anything special. only in your post section do as follows:

    $.post(yourURL,{ '': results})(function(e){ ...}

In server use this:

   public ActionResult MethodName(List<yourViewModel> model){...}

this link help you to done ...

Following @Aravind's answer with more details

@RequestMapping("/myPath.htm")
public ModelAndView add(HttpServletRequest request, HttpServletResponse response) throws Exception{
    myServiceMethodSettingCookie(request, response);        //Do service call passing the response
    return new ModelAndView("CustomerAddView");
}

// service method
void myServiceMethodSettingCookie(HttpServletRequest request, HttpServletResponse response){
    final String cookieName = "my_cool_cookie";
    final String cookieValue = "my cool value here !";  // you could assign it some encoded value
    final Boolean useSecureCookie = false;
    final int expiryTime = 60 * 60 * 24;  // 24h in seconds
    final String cookiePath = "/";

    Cookie cookie = new Cookie(cookieName, cookieValue);

    cookie.setSecure(useSecureCookie);  // determines whether the cookie should only be sent using a secure protocol, such as HTTPS or SSL

    cookie.setMaxAge(expiryTime);  // A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

    cookie.setPath(cookiePath);  // The cookie is visible to all the pages in the directory you specify, and all the pages in that directory's subdirectories

    response.addCookie(cookie);
}

Instal aws cli via homebrew package manager. It is the simplest and easiest method.

1. If you dont have homebrew installed , enter this command in your terminal

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Next 'brew install awscli'

This will install aws cli on your mac

This is easy to do with a terms panel:

If you want to select the count of distinct IP that are in your logs, you should specify in the field clientip, you should put a big enough number in length (otherwise, it will join different IP under the same group) and specify in the style table. After adding the panel, you will have a table with IP, and the count of that IP:

I recently came across Python 3 interpreter at CompileOnline.

I've found one difference between the two constructions that bit me pretty hard.

Let's say I have:

function MyClass(){
  this.property1=[];
  this.property2=new Array();
};
var MyObject1=new MyClass();
var MyObject2=new MyClass();

In real life, if I do this:

MyObject1.property1.push('a');
MyObject1.property2.push('b');
MyObject2.property1.push('c');
MyObject2.property2.push('d');

What I end up with is this:

MyObject1.property1=['a','c']
MyObject1.property2=['b']
MyObject2.property1=['a','c']
MyObject2.property2=['d']

I don't know what the language specification says is supposed to happen, but if I want my two objects to have unique property arrays in my objects, I have to use new Array().

I'd use a different data structure, since array seem to be not the best solution.

Instead of array, use an object as a hash-table, like so:

(posted also in jsbin)

var arr = ["x", "y", "z"];
var map = {};
for (var k=0; k < arr.length; ++k) {
  map[arr[k]] = true;
}

function is_in_map(key) {
  try {
    return map[key] === true;
  } catch (e) {
    return false;
  }
}


function print_check(key) {
  console.log(key + " exists? - " + (is_in_map(key) ? "yes" : "no"));
}

print_check("x");
print_check("a");

Console output:

x exists? - yes
a exists? - no

That's a straight-forward solution. If you're more into an object oriented approach, then search Google for "js hashtable".

As other people have commented above, using TRUNC will prevent the use of indexes (if there was an index on TIME_CREATED). To avoid that problem, the query can be structured as

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TIME_CREATED BETWEEN TO_DATE('26/JAN/2011','dd/mon/yyyy') 
            AND TO_DATE('26/JAN/2011','dd/mon/yyyy') + INTERVAL '86399' second;

86399 being 1 second less than the number of seconds in a day.

When render_template() function is used it tries to search for template in the folder called templates and it throws error jinja2.exceptions.TemplateNotFound when :

1. the html file do not exist or
2. when templates folder do not exist

To solve the problem :

create a folder with name templates in the same directory where the python file is located and place the html file created in the templates folder.

Use the charAt method. This function accepts one argument: The index of the character.

var lastCHar = myString.charAt(myString.length-1);

There are also several graphing libraries available for PHP to make your life simpler. JPGraph is a good (non-free) one.

I am using Android Studio 2.1.2. I had same requirement as OP. Though above two answer seemed to help everyone, it did not work for me . I am sharing what worked for me.

Go to main menu/Run/Edit Configuration . Select app under Android Application on the left.This should open multi-tabbed pane . Select General tab ( would be default), click green + sing at the bottom ( below text Before launch: Gradle -awake ...).

A drop down will appear, select Gradle-aware-make option. Another text box will pop up. enter :app:uninstallAll in this text box . (You can use ctrl + space to use autocomplete todetermine right target without typing everything . And also helps you choose the right app name that is avaiable for you). and set apply/ok. Relaunch your app.

Note : Every time you launch your app now , this new target will try to uninstall your app from your emulator or device. So if your testing device is not available, your launc will probably fail while uninstalling but will continue to start your emulator. So Either start your emulator first, or re-lauch after first fail again ( as first launch will start emulator though uninstall fails).

The count method of NSArray returns an NSUInteger, and on the 64-bit OS X platform

• NSUInteger is defined as unsigned long, and
• unsigned long is a 64-bit unsigned integer.
• int is a 32-bit integer.

So int is a "smaller" datatype than NSUInteger, therefore the compiler warning.

See also NSUInteger in the "Foundation Data Types Reference":

When building 32-bit applications, NSUInteger is a 32-bit unsigned integer. A 64-bit application treats NSUInteger as a 64-bit unsigned integer.

To fix that compiler warning, you can either declare the local count variable as

NSUInteger count;

or (if you are sure that your array will never contain more than 2^31-1 elements!), add an explicit cast:

int count = (int)[myColors count];

This can be solved by using https://twitter.com/intent/tweet instead of http://www.twitter.com/share. Using the intent/tweet function, you simply URL encode your entire URL and it works like a charm.

Another way :

/**
 * This API will return particular object value from JSON Object hierarchy.
 *
 * @param jsonData : json type : JSON data from which we want to get particular object
 * @param objHierarchy : string type : Hierarchical representation of object we want to get,
 *                       For example, 'jsonData.Envelope.Body["return"].patient' OR 'jsonData.Envelope.return.patient'
 *                       Minimal Requirements : 'X.Y' required.
 * @returns evaluated value of objHierarchy from jsonData passed.
 */
function evalJSONData(jsonData, objHierarchy){
    
    if(!jsonData || !objHierarchy){
        return null;
    }
    
    if(objHierarchy.indexOf('["return"]') !== -1){
        objHierarchy = objHierarchy.replace('["return"]','.return');
    }
    
    let objArray = objHierarchy.split(".");
    if(objArray.length === 2){
        return jsonData[objArray[1]];
    }
    return evalJSONData(jsonData[objArray[1]], objHierarchy.substring(objHierarchy.indexOf(".")+1));
}

Both styles are used within the Go's standard libraries.

if len(s) > 0 { ... }

can be found in the strconv package: http://golang.org/src/pkg/strconv/atoi.go

if s != "" { ... }

can be found in the encoding/json package: http://golang.org/src/pkg/encoding/json/encode.go

Both are idiomatic and are clear enough. It is more a matter of personal taste and about clarity.

Russ Cox writes in a golang-nuts thread:

The one that makes the code clear.
If I'm about to look at element x I typically write
len(s) > x, even for x == 0, but if I care about
"is it this specific string" I tend to write s == "".

It's reasonable to assume that a mature compiler will compile
len(s) == 0 and s == "" into the same, efficient code.
...

Make the code clear.

As pointed out in Timmmm's answer, the Go compiler does generate identical code in both cases.

Since you want to do it in relative positioning, you should go for margin-top:100%

position:relative;
margin-top:100%;

public class Main {

    public static void main(String[] argv) throws Exception {

Simply, change

<textarea rows="15" cols="50" id="aboutDescription"
style="resize: none;"></textarea>

to

<textarea rows="15" cols="50" id="aboutDescription"
style="resize: none;" data-role="none"></textarea>

ie, add:

data-role="none"

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

On a fresh install on CENTOS7 I have tried the above methods (edit phpMyAdmin.conf and add Require all granted), it still does'nt work. Here is the solution : install the mod_php module :

$ sudo yum install php

then restart httpd :

$ sudo systemctl restart httpd

and voila !

In case you want to have a default text as a sort of placeholder/hint but not considered a valid value (something like "complete here", "select your nation" ecc.) you can do something like this:

<select>_x000D_
  <option value="" selected disabled hidden>Choose here</option>_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
  <option value="4">Four</option>_x000D_
  <option value="5">Five</option>_x000D_
</select>

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

Suppose access a proxy server A(eg. nginx), and the server A forwards the request to another server B(eg. tomcat).

If this process continues for a long time (more than the proxy server read timeout setting), A still did not get a completed response of B. It happens.

for nginx, You can configure the proxy_read_timeout(in location) property to solve his.But this is usually not a good idea, if you set the value too high. This may hide the real error.You'd better improve the design to really solve this problem.

That is illegal syntax. It is not an optional thing for you to return a variable. You MUST return a variable of the type you specify in your method.

public String myMethod()
{
    if(condition)
    {
       return x;
    }
}

You are effectively saying, I promise any class can use this method(public) and I promise it will always return a String(String).

Then you are saying IF my condition is true I will return x. Well that is too bad, there is no IF in your promise. You promised that myMethod will ALWAYS return a String. Even if your condition is ALWAYS true the compiler has to assume that there is a possibility of it being false. Therefore you always need to put a return at the end of your non-void method outside of any conditions JUST IN CASE all of your conditions fail.

public String myMethod()
{
    if(condition)
    {
       return x;
    }
  return ""; //or whatever the default behavior will be if all of your conditions fail to return.
}

First install the rjson package:

install.packages("rjson")

Then:

library("rjson")
json_file <- "http://api.worldbank.org/country?per_page=10&region=OED&lendingtype=LNX&format=json"
json_data <- fromJSON(paste(readLines(json_file), collapse=""))

Update: since version 0.2.1

json_data <- fromJSON(file=json_file)

EDIT: as_matrix is deprecated since version 0.23.0

You can use the built in values or to_numpy (recommended option) method on the dataframe:

In [8]:
df.to_numpy()

Out[8]:
array([[  0.9,   7. ,   5.2, ...,  13.3,  13.5,   8.9],
   [  0.9,   7. ,   5.2, ...,  13.3,  13.5,   8.9],
   [  0.8,   6.1,   5.4, ...,  15.9,  14.4,   8.6],
   ..., 
   [  0.2,   1.3,   2.3, ...,  16.1,  16.1,  10.8],
   [  0.2,   1.3,   2.4, ...,  16.5,  15.9,  11.4],
   [  0.2,   1.3,   2.4, ...,  16.5,  15.9,  11.4]])

If you explicitly want lists and not a numpy array add .tolist():

df.to_numpy().tolist()

For Each row As DataRow In dtDataTable.Rows
    strDetail = row.Item("Detail")
Next row

There's also a shorthand:

For Each row As DataRow In dtDataTable.Rows
    strDetail = row("Detail")
Next row

Note that Microsoft's style guidelines for .Net now specifically recommend against using hungarian type prefixes for variables. Instead of "strDetail", for example, you should just use "Detail".

You are getting Floating point exception because Number % i, when i is 0:

int Is_Prime( int Number ){

  int i ;

  for( i = 0 ; i < Number / 2 ; i++ ){

    if( Number % i != 0 ) return -1 ;

  }

  return Number ;

}

Just start the loop at i = 2. Since i = 1 in Number % i it always be equal to zero, since Number is a int.

This is how i implemented strtok, Not that great but after working 2 hr on it finally got it worked. It does support multiple delimiters.

#include "stdafx.h"
#include <iostream>
using namespace std;

char* mystrtok(char str[],char filter[]) 
{
    if(filter == NULL) {
        return str;
    }
    static char *ptr = str;
    static int flag = 0;
    if(flag == 1) {
        return NULL;
    }
    char* ptrReturn = ptr;
    for(int j = 0; ptr != '\0'; j++) {
        for(int i=0 ; filter[i] != '\0' ; i++) {
            if(ptr[j] == '\0') {
                flag = 1;
                return ptrReturn;
            }
            if( ptr[j] == filter[i]) {
                ptr[j] = '\0';
                ptr+=j+1;
                return ptrReturn;
            }
        }
    }
    return NULL;
}

int _tmain(int argc, _TCHAR* argv[])
{
    char str[200] = "This,is my,string.test";
    char *ppt = mystrtok(str,", .");
    while(ppt != NULL ) {
        cout<< ppt << endl;
        ppt = mystrtok(NULL,", ."); 
    }
    return 0;
}

Imagine you have have a Book model and a Page model,

1:N means:
One book can have **many** pages. One page can only be in **one** book.


N:N means:
One book can have **many** pages. And one page can be in **many** books.

Use DecimalFormat

 NumberFormat nf = DecimalFormat.getInstance(Locale.ENGLISH);
 DecimalFormat decimalFormatter = (DecimalFormat) nf;
 decimalFormatter.applyPattern("#,###,###.##");
 String fString = decimalFormatter.format(myDouble);
 System.out.println(fString);

This worked for me

    Object[][] bookData = { { "col1", "col2", 3 }, { "col1", "col2", 3 }, { "col1", "col2", 3 },
            { "col1", "col2", 3 }, { "col1", "col2", 3 }, { "col1", "col2", 3 } };

    String[] headers = new String[] { "HEader 1", "HEader 2", "HEader 3" };

    int noOfColumns = headers.length;
    int rowCount = 0;

    Row rowZero = sheet.createRow(rowCount++);
    CellStyle style = workbook.createCellStyle();
    Font font = workbook.createFont();
    font.setBoldweight(Font.BOLDWEIGHT_BOLD);
    style.setFont(font);
    for (int col = 1; col <= noOfColumns; col++) {
        Cell cell = rowZero.createCell(col);
        cell.setCellValue(headers[col - 1]);
        cell.setCellStyle(style);
    }

May not be the best approach but... Using react-router v4, the following Typescript could give an idea for some.

Timer

As mentioned on the javadocs you are better off using a ScheduledThreadPoolExecutor.

ScheduledThreadPoolExecutor

Use this class when your use case requires multiple worker threads and the sleep interval is small. How small ? Well, I'd say about 15 minutes. The AlarmManager starts schedule intervals at this time and it seems to suggest that for smaller sleep intervals this class can be used. I do not have data to back the last statement. It is a hunch.

Service

Your service can be closed any time by the VM. Do not use services for recurring tasks. A recurring task can start a service, which is another matter entirely.

BroadcastReciever with AlarmManager

For longer sleep intervals (>15 minutes), this is the way to go. AlarmManager already has constants ( AlarmManager.INTERVAL_DAY ) suggesting that it can trigger tasks several days after it has initially been scheduled. It can also wake up the CPU to run your code.

You should use one of those solutions based on your timing and worker thread needs.

Ben Dryer's answer didn't compile on my machine ("The method until(Predicate<WebDriver>) is ambiguous for the type WebDriverWait").

Working Java 8 version:

Predicate<WebDriver> pageLoaded = wd -> ((JavascriptExecutor) wd).executeScript(
        "return document.readyState").equals("complete");
new FluentWait<WebDriver>(driver).until(pageLoaded);

Java 7 version:

Predicate<WebDriver> pageLoaded = new Predicate<WebDriver>() {

        @Override
        public boolean apply(WebDriver input) {
            return ((JavascriptExecutor) input).executeScript("return document.readyState").equals("complete");
        }

};
new FluentWait<WebDriver>(driver).until(pageLoaded);

This works nicely

def running():

    for task in prog:
        if task[0]=="itunes.exe":

Had the same ssl-problem on my developer machine (php 7, xampp on windows) with a self signed certificate trying to fopen a "https://localhost/..."-file. Obviously the root-certificate-assembly (cacert.pem) didn't work. I just copied manually the code from the apache server.crt-File in the downloaded cacert.pem and did the openssl.cafile=path/to/cacert.pem entry in php.ini

I had the same problem and then wrote this shell script which kills all of the existing node processes:

#!/bin/bash
echo "The following node processes were found:"
ps aux | grep " node " | grep -v grep
nodepids=$(ps aux | grep " node " | grep -v grep | cut -c10-15)

echo "OK, so we will stop these process/es now..."

for nodepid in ${nodepids[@]}
do
echo "Stopping PID :"$nodepid
kill -9 $nodepid
done
echo "Done"

After this is saved as a shell script (xxx.sh) file you might want to add it to your PATH as described here.

(Please note that this will kill all of the processes with " node " in it's name except grep's own, so I guess in some cases it may also kill some other processes with a similar name)

Put its content in a span which is relatively positioned, then you can control the space by the left property of the span.

li span {_x000D_
  position: relative;_x000D_
  left: -10px;_x000D_
}

<ul>_x000D_
  <li><span>item 1</span></li>_x000D_
  <li><span>item 2</span></li>_x000D_
  <li><span>item 3</span></li>_x000D_
</ul>

If no space, Why not this?

IN="[email protected];[email protected]"
arr=(`echo $IN | tr ';' ' '`)

echo ${arr[0]}
echo ${arr[1]}

Or if you like to mix outputs (stdout & stderr) in one single file you may want to use:

command > merged-output.txt 2>&1

when you use Interface Builder, you can use Connections Inspector to set up the events with event handlers, the event handlers are supposed to be the functions that have the IBAction modifier. A view can be linked with the reference for the same type and with the IBOutlet modifier.

I understood the question as "How do I match a word but exclude another", for which one solution is two greps in series: First grep finding the wanted "word1", second grep excluding "word2":

grep "word1" | grep -v "word2"

In my case: I need to differentiate between "plot" and "#plot" which grep's "word" option won't do ("#" not being a alphanumerical).

Hope this helps.

Following SierraX and Peter's suggestion about text manipulation, curly brackets {} are used to pass a variable to a command, for instance:

Let's say you have a sposi.txt file containing the first line of a well-known Italian novel:

> sposi="somewhere/myfolder/sposi.txt"
> cat $sposi

Ouput: quel ramo del lago di como che volge a mezzogiorno

Now create two variables:

# Search the 2nd word found in the file that "sposi" variable points to
> word=$(cat $sposi | cut -d " " -f 2)

# This variable will replace the word
> new_word="filone"

Now substitute the word variable content with the one of new_word, inside sposi.txt file

> sed -i "s/${word}/${new_word}/g" $sposi
> cat $sposi

Ouput: quel filone del lago di como che volge a mezzogiorno

The word "ramo" has been replaced.

For this particular purpose, $("span").show() should be good enough.

The CompletionService will take your Callables with the .submit() method and you can retrieve the computed futures with the .take() method.

One thing you must not forget is to terminate the ExecutorService by calling the .shutdown() method. Also you can only call this method when you have saved a reference to the executor service so make sure to keep one.

Example code - For a fixed number of work items to be worked on in parallel:

ExecutorService service = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors());

CompletionService<YourCallableImplementor> completionService = 
new ExecutorCompletionService<YourCallableImplementor>(service);

ArrayList<Future<YourCallableImplementor>> futures = new ArrayList<Future<YourCallableImplementor>>();

for (String computeMe : elementsToCompute) {
    futures.add(completionService.submit(new YourCallableImplementor(computeMe)));
}
//now retrieve the futures after computation (auto wait for it)
int received = 0;

while(received < elementsToCompute.size()) {
 Future<YourCallableImplementor> resultFuture = completionService.take(); 
 YourCallableImplementor result = resultFuture.get();
 received ++;
}
//important: shutdown your ExecutorService
service.shutdown();

Example code - For a dynamic number of work items to be worked on in parallel:

public void runIt(){
    ExecutorService service = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors());
    CompletionService<CallableImplementor> completionService = new ExecutorCompletionService<CallableImplementor>(service);
    ArrayList<Future<CallableImplementor>> futures = new ArrayList<Future<CallableImplementor>>();

    //Initial workload is 8 threads
    for (int i = 0; i < 9; i++) {
        futures.add(completionService.submit(write.new CallableImplementor()));             
    }
    boolean finished = false;
    while (!finished) {
        try {
            Future<CallableImplementor> resultFuture;
            resultFuture = completionService.take();
            CallableImplementor result = resultFuture.get();
            finished = doSomethingWith(result.getResult());
            result.setResult(null);
            result = null;
            resultFuture = null;
            //After work package has been finished create new work package and add it to futures
            futures.add(completionService.submit(write.new CallableImplementor()));
        } catch (InterruptedException | ExecutionException e) {
            //handle interrupted and assert correct thread / work packet count              
        } 
    }

    //important: shutdown your ExecutorService
    service.shutdown();
}

public class CallableImplementor implements Callable{
    boolean result;

    @Override
    public CallableImplementor call() throws Exception {
        //business logic goes here
        return this;
    }

    public boolean getResult() {
        return result;
    }

    public void setResult(boolean result) {
        this.result = result;
    }
}

If you use explicit anchor names such as,

<a name="sectionLink"></a>
<h1>Section<h1>

then in css you can simply set

A[name] {
    padding-top:100px;
}

This will work as long as your HREF anchor tags don't also specify a NAME attribute

All you need is a <clear /> tag. Here's an example:

<configuration>
  <system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

For authoritative information about these files, check out the man pages, run the command on your terminal.

$ man stdout 

But for a simple answer, each file is for:

stdout for a stream out

stdin for a stream input

stderr for printing errors or log messages.

Each unix program has each one of those streams.

Kindly ensure, the other columns are not constrained to accept Not null values, hence while creating columns in table just ignore "Not Null" syntax. eg

Create Table Table_Name(
            col1 DataType,
            col2 DataType);

You can then insert multiple row values in any of the columns you want to. For instance:

Insert Into TableName(columnname)
values
      (x),
      (y),
      (z);

and so on…

Hope this helps.

What you could do is, a validation of the values, for example:

if the value of the input of fullanme is greater than some value length and if the value of the input of address is greater than some value length then redirect to a new page, otherwise shows an error for the input.

// We access to the inputs by their id's
let fullname = document.getElementById("fullname");
let address = document.getElementById("address");

// Error messages
let errorElement = document.getElementById("name_error");
let errorElementAddress = document.getElementById("address_error");

// Form
let contactForm = document.getElementById("form");

// Event listener
contactForm.addEventListener("submit", function (e) {
  let messageName = [];
  let messageAddress = [];
  
    if (fullname.value === "" || fullname.value === null) {
    messageName.push("* This field is required");
  }

  if (address.value === "" || address.value === null) {
    messageAddress.push("* This field is required");
  }

  // Statement to shows the errors
  if (messageName.length || messageAddress.length > 0) {
    e.preventDefault();
    errorElement.innerText = messageName;
    errorElementAddress.innerText = messageAddress;
  }
  
   // if the values length is filled and it's greater than 2 then redirect to this page
    if (
    (fullname.value.length > 2,
    address.value.length > 2)
  ) {
    e.preventDefault();
    window.location.assign("https://www.google.com");
  }

});

.error {
  color: #000;
}

.input-container {
  display: flex;
  flex-direction: column;
  margin: 1rem auto;
}

<html>

So,. I had this issue,. except I got [object object]

I'm sure you could do this with recursion but this worked for me:

Here is what I did in my console:

var object_that_is_not_shallow = $("all_obects_with_this_class_name");
var str = '';
object_that_is_not_shallow.map(function(_,e){
    str += $(e).html();
});
copy(str);

Then paste into your editor.

words = x.split("_")
for word in words:
    if word[0] == word[0].upper() and word[1:] == word[1:].lower():
        print word, "is conformant"
    else:
        print word, "is non conformant"

Dynamic programming problems can be solved using either bottom-up or top-down approaches.

Generally, the bottom-up approach uses the tabulation technique, while the top-down approach uses the recursion (with memorization) technique.

But you can also have bottom-up and top-down approaches using recursion as shown below.

Bottom-Up: Start with the base condition and pass the value calculated until now recursively. Generally, these are tail recursions.

int n = 5;
fibBottomUp(1, 1, 2, n);

private int fibBottomUp(int i, int j, int count, int n) {
    if (count > n) return 1;
    if (count == n) return i + j;
    return fibBottomUp(j, i + j, count + 1, n);
}

Top-Down: Start with the final condition and recursively get the result of its sub-problems.

int n = 5;
fibTopDown(n);

private int fibTopDown(int n) {
    if (n <= 1) return 1;
    return fibTopDown(n - 1) + fibTopDown(n - 2);
}

You should use the * operator, like foo(*values) Read the Python doc unpackaging argument lists.

Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

def foo(x,y,z):
   return "%d, %d, %d" % (x,y,z)

values = [1,2,3]

# the solution.
foo(*values)

I fixed this by installing a newer version of Git. The version I installed is 2.10.2 from https://git-scm.com. See the last post here: https://www.bountysource.com/issues/31602800-git-fails-to-authenticate-access-to-private-repository-over-https

With newer Git Bash, the credential manager window pops up and you can enter your username and password, and it works!

This answer will do what you need, although usually you don't add specific usernames to sudoers. Instead, you have a group of sudoers and just add your user to that group when needed. This way you don't need to use visudo more than once when giving sudo permission to users.

If you're on Ubuntu, the group is most probably already set up and called admin:

$ sudo cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#

...

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

On other distributions, like Arch and some others, it's usually called wheel and you may need to set it up: Arch Wiki

To give users in the wheel group full root privileges when they precede a command with "sudo", uncomment the following line: %wheel ALL=(ALL) ALL

Also note that on most systems visudo will read the EDITOR environment variable or default to using vi. So you can try to do EDITOR=vim visudo to use vim as the editor.

To add a user to the group you should run (as root):

# usermod -a -G groupname username

where groupname is your group (say, admin or wheel) and username is the username (say, john).

I installed MySQL as root user($SUDO) and got this same issue
Here is how I fixed it-

1. $ sudo cat /etc/mysql/debian.cnf

This will show details as-

# Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock

Above we can see password just we are going to use(GUx0RblkD3sPhHL5) that in the prompt-

2. mysql -u debian-sys-maint -p Enter password:
   now provide password(GUx0RblkD3sPhHL5).

3. Now exit from MySQL and login again as-

   mysql -u root -p Enter password:
   Now provide new password. That's all, we have new password for further uses.

It worked for me, hope help you too!

special_func to avoid try-except repetition:

def special_func(test_case_dict):
    final_dict = {}
    exception_dict = {}

    def try_except_avoider(test_case_dict):

        try:
            for k,v in test_case_dict.items():
                final_dict[k]=eval(v) #If no exception evaluate the function and add it to final_dict

        except Exception as e:
            exception_dict[k]=e #extract exception
            test_case_dict.pop(k)
            try_except_avoider(test_case_dict) #recursive function to handle remaining functions

        finally:  #cleanup
            final_dict.update(exception_dict)
            return final_dict #combine exception dict and  final dict

    return try_except_avoider(test_case_dict) 

Run code:

def add(a,b):
    return (a+b)
def sub(a,b):
    return (a-b)
def mul(a,b):
    return (a*b)

case = {"AddFunc":"add(8,8)","SubFunc":"sub(p,5)","MulFunc":"mul(9,6)"}
solution = special_func(case)

Output looks like:

{'AddFunc': 16, 'MulFunc': 54, 'SubFunc': NameError("name 'p' is not defined")}

To convert to variables:

locals().update(solution)

Variables would look like:

AddFunc = 16, MulFunc = 54, SubFunc = NameError("name 'p' is not defined")

Google actually let the cat out of the bag on this one. They were using it for a while to access tracking cookies. It was fixed almost immediately by Apple =\

original Wall Street Journal post

Try this. It's working for me (Windows 10).

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

# Define the codec and create VideoWriter object
#fourcc = cv2.cv.CV_FOURCC(*'DIVX')
#out = cv2.VideoWriter('output.avi',fourcc, 20.0, (640,480))
out = cv2.VideoWriter('output.avi', -1, 20.0, (640,480))

while(cap.isOpened()):
    ret, frame = cap.read()
    if ret==True:
        frame = cv2.flip(frame,0)

        # write the flipped frame
        out.write(frame)

        cv2.imshow('frame',frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    else:
        break

# Release everything if job is finished
cap.release()
out.release()
cv2.destroyAllWindows()

You can make it like this:

    MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    RequestBody body = RequestBody.create(JSON, "{"jsonExample":"value"}");

    OkHttpClient client = new OkHttpClient();

    Request request = new Request.Builder()
            .url(url)
            .post(body)
            .addHeader("Authorization", "header value") //Notice this request has header if you don't need to send a header just erase this part
            .build();

    Call call = client.newCall(request);

    call.enqueue(new Callback() {
        @Override
        public void onFailure(Request request, IOException e) {

            Log.e("HttpService", "onFailure() Request was: " + request);

            e.printStackTrace();
        }

        @Override
        public void onResponse(Response r) throws IOException {

            response = r.body().string();

            Log.e("response ", "onResponse(): " + response );

        }
    });

html {
  min-height: 100%;
}

body {
  min-height: 100vh;
}

The html height (%) will take care of the height of the documents that's height is more than a 100% of the screen view while the body view height (vh) will take care of the document's height that is less than the height of the screen view.

Ajax forms work asynchronously using Javascript. So it is required, to load the script files for execution. Even though it's a small performance compromise, the execution happens without postback.

We need to understand the difference between the behaviours of both Html and Ajax forms.

Ajax:

1. Won't redirect the form, even you do a RedirectAction().

2. Will perform save, update and any modification operations asynchronously.

Html:

1. Will redirect the form.

2. Will perform operations both Synchronously and Asynchronously (With some extra code and care).

Demonstrated the differences with a POC in below link. Link

you can add the 1px border to just the sides and bottom of each row. the first value is the top border, the second is the right border, the third is the bottom border, and the fourth is the left border.

div.row {
  border: 0px 1px 1px 1px solid;
}

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

Update 2016/6: For aspect ratio and positioning (ala CSS' "cover" method), check out:
Simulation background-size: cover in canvas

I created the Path Length Checker tool for this purpose, which is a nice, free GUI app that you can use to see the path lengths of all files and directories in a given directory.

I've also written and blogged about a simple PowerShell script for getting file and directory lengths. It will output the length and path to a file, and optionally write it to the console as well. It doesn't limit to displaying files that are only over a certain length (an easy modification to make), but displays them descending by length, so it's still super easy to see which paths are over your threshold. Here it is:

$pathToScan = "C:\Some Folder"  # The path to scan and the the lengths for (sub-directories will be scanned as well).
$outputFilePath = "C:\temp\PathLengths.txt" # This must be a file in a directory that exists and does not require admin rights to write to.
$writeToConsoleAsWell = $true   # Writing to the console will be much slower.

# Open a new file stream (nice and fast) and write all the paths and their lengths to it.
$outputFileDirectory = Split-Path $outputFilePath -Parent
if (!(Test-Path $outputFileDirectory)) { New-Item $outputFileDirectory -ItemType Directory }
$stream = New-Object System.IO.StreamWriter($outputFilePath, $false)
Get-ChildItem -Path $pathToScan -Recurse -Force | Select-Object -Property FullName, @{Name="FullNameLength";Expression={($_.FullName.Length)}} | Sort-Object -Property FullNameLength -Descending | ForEach-Object {
    $filePath = $_.FullName
    $length = $_.FullNameLength
    $string = "$length : $filePath"

    # Write to the Console.
    if ($writeToConsoleAsWell) { Write-Host $string }

    #Write to the file.
    $stream.WriteLine($string)
}
$stream.Close()

Try this

From java documentation page

java.lang.reflect package provides classes and interfaces for obtaining reflective information about classes and objects. Reflection allows programmatic access to information about the fields, methods and constructors of loaded classes, and the use of reflected fields, methods, and constructors to operate on their underlying counterparts, within security restrictions.

AccessibleObject allows suppression of access checks if the necessary ReflectPermission is available.

Classes in this package, along with java.lang.Class accommodate applications such as debuggers, interpreters, object inspectors, class browsers, and services such as Object Serialization and JavaBeans that need access to either the public members of a target object (based on its runtime class) or the members declared by a given class

It includes following functionality.

1. Obtaining Class objects,
2. Examining properties of a class (fields, methods, constructors),
3. Setting and getting field values,
4. Invoking methods,
5. Creating new instances of objects.

Have a look at this documentation link for the methods exposed by Class class.

From this article (by Dennis Sosnoski, President, Sosnoski Software Solutions, Inc) and this article (security-explorations pdf):

I can see considerable drawbacks than uses of using Reflection

User of Reflection:

1. It provides very versatile way of dynamically linking program components
2. It is useful for creating libraries that work with objects in very general ways

Drawbacks of Reflection:

1. Reflection is much slower than direct code when used for field and method access.
2. It can obscure what's actually going on inside your code
3. It bypasses the source code can create maintenance problems
4. Reflection code is also more complex than the corresponding direct code
5. It allows violation of key Java security constraints such as data access protection and type safety

General abuses:

1. Loading of restricted classes,
2. Obtaining references to constructors, methods or fields of a restricted class,
3. Creation of new object instances, methods invocation, getting or setting field values of a restricted class.

Have a look at this SE question regarding abuse of reflection feature:

How do I read a private field in Java?

Summary:

Insecure use of its functions conducted from within a system code can also easily lead to the compromise of a Java security model. So use this feature sparingly

Crude, but it works on our system:

public class HiResDateTime
{
   private static long lastTimeStamp = DateTime.UtcNow.Ticks;
   public static long UtcNowTicks
   {
       get
       {
           long orig, newval;
           do
           {
               orig = lastTimeStamp;
               long now = DateTime.UtcNow.Ticks;
               newval = Math.Max(now, orig + 1);
           } while (Interlocked.CompareExchange
                        (ref lastTimeStamp, newval, orig) != orig);

           return newval;
       }
   }
}

CGFloat is a regular float on 32-bit systems and a double on 64-bit systems

typedef float CGFloat;// 32-bit
typedef double CGFloat;// 64-bit

So you won't get any performance penalty.

Try square braces with your $_COOKIE, not parenthesis. Like this:

<?php
if ($_COOKIE['CaptchaResponseValue'] == "false")
{
    header('Location: index.php');
    return;
}
?>

I also corrected your location header call a little too.

try that way:

dfo = sorted(df.time_diff)

n=len(dfo)

Q1=int((n+3)/4)  
Q3=int((3*n+1)/4)  


print("Q1 position: ", Q1, "Q1 position: " ,Q3)

print("Q1 value: ", dfo[Q1], "Q1 value: ", dfo[Q3])

Well, you could look it up in Wikipedia... But since you want an explanation, I'll do my best here:

Hash Functions

They provide a mapping between an arbitrary length input, and a (usually) fixed length (or smaller length) output. It can be anything from a simple crc32, to a full blown cryptographic hash function such as MD5 or SHA1/2/256/512. The point is that there's a one-way mapping going on. It's always a many:1 mapping (meaning there will always be collisions) since every function produces a smaller output than it's capable of inputting (If you feed every possible 1mb file into MD5, you'll get a ton of collisions).

The reason they are hard (or impossible in practicality) to reverse is because of how they work internally. Most cryptographic hash functions iterate over the input set many times to produce the output. So if we look at each fixed length chunk of input (which is algorithm dependent), the hash function will call that the current state. It will then iterate over the state and change it to a new one and use that as feedback into itself (MD5 does this 64 times for each 512bit chunk of data). It then somehow combines the resultant states from all these iterations back together to form the resultant hash.

Now, if you wanted to decode the hash, you'd first need to figure out how to split the given hash into its iterated states (1 possibility for inputs smaller than the size of a chunk of data, many for larger inputs). Then you'd need to reverse the iteration for each state. Now, to explain why this is VERY hard, imagine trying to deduce a and b from the following formula: 10 = a + b. There are 10 positive combinations of a and b that can work. Now loop over that a bunch of times: tmp = a + b; a = b; b = tmp. For 64 iterations, you'd have over 10^64 possibilities to try. And that's just a simple addition where some state is preserved from iteration to iteration. Real hash functions do a lot more than 1 operation (MD5 does about 15 operations on 4 state variables). And since the next iteration depends on the state of the previous and the previous is destroyed in creating the current state, it's all but impossible to determine the input state that led to a given output state (for each iteration no less). Combine that, with the large number of possibilities involved, and decoding even an MD5 will take a near infinite (but not infinite) amount of resources. So many resources that it's actually significantly cheaper to brute-force the hash if you have an idea of the size of the input (for smaller inputs) than it is to even try to decode the hash.

Encryption Functions

They provide a 1:1 mapping between an arbitrary length input and output. And they are always reversible. The important thing to note is that it's reversible using some method. And it's always 1:1 for a given key. Now, there are multiple input:key pairs that might generate the same output (in fact there usually are, depending on the encryption function). Good encrypted data is indistinguishable from random noise. This is different from a good hash output which is always of a consistent format.

Use Cases

Use a hash function when you want to compare a value but can't store the plain representation (for any number of reasons). Passwords should fit this use-case very well since you don't want to store them plain-text for security reasons (and shouldn't). But what if you wanted to check a filesystem for pirated music files? It would be impractical to store 3 mb per music file. So instead, take the hash of the file, and store that (md5 would store 16 bytes instead of 3mb). That way, you just hash each file and compare to the stored database of hashes (This doesn't work as well in practice because of re-encoding, changing file headers, etc, but it's an example use-case).

Use a hash function when you're checking validity of input data. That's what they are designed for. If you have 2 pieces of input, and want to check to see if they are the same, run both through a hash function. The probability of a collision is astronomically low for small input sizes (assuming a good hash function). That's why it's recommended for passwords. For passwords up to 32 characters, md5 has 4 times the output space. SHA1 has 6 times the output space (approximately). SHA512 has about 16 times the output space. You don't really care what the password was, you care if it's the same as the one that was stored. That's why you should use hashes for passwords.

Use encryption whenever you need to get the input data back out. Notice the word need. If you're storing credit card numbers, you need to get them back out at some point, but don't want to store them plain text. So instead, store the encrypted version and keep the key as safe as possible.

Hash functions are also great for signing data. For example, if you're using HMAC, you sign a piece of data by taking a hash of the data concatenated with a known but not transmitted value (a secret value). So, you send the plain-text and the HMAC hash. Then, the receiver simply hashes the submitted data with the known value and checks to see if it matches the transmitted HMAC. If it's the same, you know it wasn't tampered with by a party without the secret value. This is commonly used in secure cookie systems by HTTP frameworks, as well as in message transmission of data over HTTP where you want some assurance of integrity in the data.

A note on hashes for passwords:

A key feature of cryptographic hash functions is that they should be very fast to create, and very difficult/slow to reverse (so much so that it's practically impossible). This poses a problem with passwords. If you store sha512(password), you're not doing a thing to guard against rainbow tables or brute force attacks. Remember, the hash function was designed for speed. So it's trivial for an attacker to just run a dictionary through the hash function and test each result.

Adding a salt helps matters since it adds a bit of unknown data to the hash. So instead of finding anything that matches md5(foo), they need to find something that when added to the known salt produces md5(foo.salt) (which is very much harder to do). But it still doesn't solve the speed problem since if they know the salt it's just a matter of running the dictionary through.

So, there are ways of dealing with this. One popular method is called key strengthening (or key stretching). Basically, you iterate over a hash many times (thousands usually). This does two things. First, it slows down the runtime of the hashing algorithm significantly. Second, if implemented right (passing the input and salt back in on each iteration) actually increases the entropy (available space) for the output, reducing the chances of collisions. A trivial implementation is:

var hash = password + salt;
for (var i = 0; i < 5000; i++) {
    hash = sha512(hash + password + salt);
}

There are other, more standard implementations such as PBKDF2, BCrypt. But this technique is used by quite a few security related systems (such as PGP, WPA, Apache and OpenSSL).

The bottom line, hash(password) is not good enough. hash(password + salt) is better, but still not good enough... Use a stretched hash mechanism to produce your password hashes...

Another note on trivial stretching

Do not under any circumstances feed the output of one hash directly back into the hash function:

hash = sha512(password + salt); 
for (i = 0; i < 1000; i++) {
    hash = sha512(hash); // <-- Do NOT do this!
}

The reason for this has to do with collisions. Remember that all hash functions have collisions because the possible output space (the number of possible outputs) is smaller than then input space. To see why, let's look at what happens. To preface this, let's make the assumption that there's a 0.001% chance of collision from sha1() (it's much lower in reality, but for demonstration purposes).

hash1 = sha1(password + salt);

Now, hash1 has a probability of collision of 0.001%. But when we do the next hash2 = sha1(hash1);, all collisions of hash1 automatically become collisions of hash2. So now, we have hash1's rate at 0.001%, and the 2nd sha1() call adds to that. So now, hash2 has a probability of collision of 0.002%. That's twice as many chances! Each iteration will add another 0.001% chance of collision to the result. So, with 1000 iterations, the chance of collision jumped from a trivial 0.001% to 1%. Now, the degradation is linear, and the real probabilities are far smaller, but the effect is the same (an estimation of the chance of a single collision with md5 is about 1/(2¹²⁸) or 1/(3x10³⁸). While that seems small, thanks to the birthday attack it's not really as small as it seems).

Instead, by re-appending the salt and password each time, you're re-introducing data back into the hash function. So any collisions of any particular round are no longer collisions of the next round. So:

hash = sha512(password + salt);
for (i = 0; i < 1000; i++) {
    hash = sha512(hash + password + salt);
}

Has the same chance of collision as the native sha512 function. Which is what you want. Use that instead.

If your code is prepared to deal with overflow errors, you can throw an exception if data is too large.

size_t data = 99999999;
if ( data > INT_MAX )
{
   throw std::overflow_error("data is larger than INT_MAX");
}
int convertData = static_cast<int>(data);
