To select a checkbox, use the "WebElement" class.

To operate on a drop-down list, use the "Select" class.

You can change the background color of the <CheckBox> by embedding it inside a <LinearLayout>. Then change the background color of <LinearLayout> to the color you want.

This isn't strictly SQL language, but in SQL Server if your database collation is case-sensitive, then all table names are case-sensitive.

My question is, is there a wizard or automatic importer for converting an existing Eclipse Java project to a Maven project, using the Maven plugin?

As far as I know, there is nothing that will automagically convert an Eclipse project into a Maven project (i.e. modify the layout, create a POM, "generate" and feed it with metadata, detect libraries and their versions to add them to the POM, etc). Eclipse just doesn't have enough metadata to make this possible (this is precisely the point of the POM) and/or to produce a decent result.

Or should I create a new Maven project and manually copy over all source files, libs, etc

That would be the best option in my opinion. Create a Maven project, copy/move sources, resources, tests, test resources into their respective directories, declare dependencies, etc.

Catch all. When solutions mentioned here don't work(happend in my case), simply delete all contents from '.m2' folder/directory, and do mvn clean install.

This is equivalent to the path of the script:

%~dp0

This uses the batch parameter extension syntax. Parameter 0 is always the script itself.

If your script is stored at C:\example\script.bat, then %~dp0 evaluates to C:\example\.

ss64.com has more information about the parameter extension syntax. Here is the relevant excerpt:

You can get the value of any parameter using a % followed by it's numerical position on the command line.

[...]

When a parameter is used to supply a filename then the following extended syntax can be applied:

[...]

%~d1 Expand %1 to a Drive letter only - C:

[...]

%~p1 Expand %1 to a Path only e.g. \utils\ this includes a trailing \ which may be interpreted as an escape character by some commands.

[...]

The modifiers above can be combined:

%~dp1 Expand %1 to a drive letter and path only

[...]

You can get the pathname of the batch script itself with %0, parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script e.g. W:\scripts\

There are a lot of possible MIME types for CSV files, depending on the user's OS and browser version.

This is how I currently validate the MIME types of my CSV files:

$csv_mimetypes = array(
    'text/csv',
    'text/plain',
    'application/csv',
    'text/comma-separated-values',
    'application/excel',
    'application/vnd.ms-excel',
    'application/vnd.msexcel',
    'text/anytext',
    'application/octet-stream',
    'application/txt',
);

if (in_array($_FILES['upload']['type'], $csv_mimetypes)) {
    // possible CSV file
    // could also check for file content at this point
}

-ArgumentList is based on use with scriptblock commands, like:

Invoke-Command -Cn (gc Servers.txt) {param($Debug=$False, $Clear=$False) C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 } -ArgumentList $False,$True

When you call it with a -File it still passes the parameters like a dumb splatted array. I've submitted a feature request to have that added to the command (please vote that up).

So, you have two options:

If you have a script that looked like this, in a network location accessible from the remote machine (note that -Debug is implied because when I use the Parameter attribute, the script gets CmdletBinding implicitly, and thus, all of the common parameters):

param(
   [Parameter(Position=0)]
   $one
,
   [Parameter(Position=1)]
   $two
,
   [Parameter()]
   [Switch]$Clear
)

"The test is for '$one' and '$two' ... and we $(if($DebugPreference -ne 'SilentlyContinue'){"will"}else{"won't"}) run in debug mode, and we $(if($Clear){"will"}else{"won't"}) clear the logs after."

Without getting hung up on the meaning of $Clear ... if you wanted to invoke that you could use either of the following Invoke-Command syntaxes:

icm -cn (gc Servers.txt) { 
    param($one,$two,$Debug=$False,$Clear=$False)
    C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 @PSBoundParameters
} -ArgumentList "uno", "dos", $false, $true

In that one, I'm duplicating ALL the parameters I care about in the scriptblock so I can pass values. If I can hard-code them (which is what I actually did), there's no need to do that and use PSBoundParameters, I can just pass the ones I need to. In the second example below I'm going to pass the $Clear one, just to demonstrate how to pass switch parameters:

icm -cn $Env:ComputerName { 
    param([bool]$Clear)
    C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 "uno" "dos" -Debug -Clear:$Clear
} -ArgumentList $(Test-Path $Profile)

The other option

If the script is on your local machine, and you don't want to change the parameters to be positional, or you want to specify parameters that are common parameters (so you can't control them) you will want to get the content of that script and embed it in your scriptblock:

$script = [scriptblock]::create( @"
param(`$one,`$two,`$Debug=`$False,`$Clear=`$False)
&{ $(Get-Content C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 -delimiter ([char]0)) } @PSBoundParameters
"@ )

Invoke-Command -Script $script -Args "uno", "dos", $false, $true

PostScript:

If you really need to pass in a variable for the script name, what you'd do will depend on whether the variable is defined locally or remotely. In general, if you have a variable $Script or an environment variable $Env:Script with the name of a script, you can execute it with the call operator (&): &$Script or &$Env:Script

If it's an environment variable that's already defined on the remote computer, that's all there is to it. If it's a local variable, then you'll have to pass it to the remote script block:

Invoke-Command -cn $Env:ComputerName { 
    param([String]$Script, [bool]$Clear)
    & $ScriptPath "uno" "dos" -Debug -Clear:$Clear
} -ArgumentList $ScriptPath, (Test-Path $Profile)

If you're looking for a specific type of control you could use a recursive loop like this one - http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx

Here's an example I made that returns all controls of the given type

/// <summary>
/// Finds all controls of type T stores them in FoundControls
/// </summary>
/// <typeparam name="T"></typeparam>
private class ControlFinder<T> where T : Control 
{
    private readonly List<T> _foundControls = new List<T>();
    public IEnumerable<T> FoundControls
    {
        get { return _foundControls; }
    }    

    public void FindChildControlsRecursive(Control control)
    {
        foreach (Control childControl in control.Controls)
        {
            if (childControl.GetType() == typeof(T))
            {
                _foundControls.Add((T)childControl);
            }
            else
            {
                FindChildControlsRecursive(childControl);
            }
        }
    }
}

I finally found the solution (*.vbhtml):

function razorsyntax() {
    /* Double */
    @(MvcHtmlString.Create("var szam =" & mydoublevariable & ";"))
    alert(szam);

    /* String */
    var str = '@stringvariable';
    alert(str);
}

Sometimes marking as Warning

Windows -> Preferences -> Java-> Compiler -> Building -> Circular Dependencies

doesn't solve the problem because eclipse don't compile the projects that have another project in the dependencies that isn't compiled.

So to solve this problem you can try forcing Eclipse to compile every class that it be able to.

To make this just:

1. Deselect

Windows -> Preferences -> Java-> Compiler -> Building -> Abort build when build path error occur

2. Clean and rebuild all project

Project -> Clean...

3. Reselect:

Windows -> Preferences -> Java-> Compiler -> Building -> Abort build when build path error occur

If you have the Automatic Build selected then you will not need to do this every time that you change the code

In my case , I had removed gradlew and gradle folders from project. Reran clean build tasks through "Run Gradle Task" from Gradle Projects window in intellij

If you can't use an HTML parser oriented solution to filter out the tags, here's a simple regex for it.

string noHTML = Regex.Replace(inputHTML, @"<[^>]+>|&nbsp;", "").Trim();

You should ideally make another pass through a regex filter that takes care of multiple spaces as

string noHTMLNormalised = Regex.Replace(noHTML, @"\s{2,}", " ");

More readable way of achieving this (not a fan of single line ansible tasks)

- local_action: 
    module: copy 
    content: "{{ foo_result }}"
    dest: /path/to/destination/file

For non-preemptive system,

waitingTime = startTime - arrivalTime

turnaroundTime = burstTime + waitingTime = finishTime- arrivalTime

startTime = Time at which the process started executing

finishTime = Time at which the process finished executing

You can keep track of the current time elapsed in the system(timeElapsed). Assign all processors to a process in the beginning, and execute until the shortest process is done executing. Then assign this processor which is free to the next process in the queue. Do this until the queue is empty and all processes are done executing. Also, whenever a process starts executing, recored its startTime, when finishes, record its finishTime (both same as timeElapsed). That way you can calculate what you need.

You could also use a regular expression:

/[?&]q=/.test(location.search)

Just ad this in the select :

DATE_FORMAT($yourDate, \'%X %V\') as week

And

group_by(week);

for something that offers more performance than ''.format(), you can use this:

>>> ':'.join( '%02x'%(v if type(v) is int else ord(v)) for v in 'Hello World !!' )
'48:65:6C:6C:6F:20:77:6F:72:6C:64:20:21:21'
>>> 
>>> ':'.join( '%02x'%(v if type(v) is int else ord(v)) for v in b'Hello World !!' )
'48:65:6C:6C:6F:20:77:6F:72:6C:64:20:21:21'
>>> 

sorry this couldn't look nicer
would be nice if one could simply do '%02x'%v, but that only takes int...
but you'll be stuck with byte-strings b'' without the logic to select ord(v).

Try this using list comprehension:

import pandas as pd

df = pd.DataFrame(
    [p, p.team, p.passing_att, p.passer_rating()] for p in game.players.passing()
)

You should really import the module into its own alias.

import datetime as dt
my_datetime = dt.datetime(year, month, day)

The above has the following benefits over the other solutions:

• Calling the variable my_datetime instead of date reduces confusion since there is already a date in the datetime module (datetime.date).
• The module and the class (both called datetime) do not shadow each other.

You could even do it like this:

Example

grep -rl 'windows' ./ | xargs sed -i 's/windows/linux/g'

This will search for the string 'windows' in all files relative to the current directory and replace 'windows' with 'linux' for each occurrence of the string in each file.

Because for...in enumerates through the object that holds the array, not the array itself. If I add a function to the arrays prototype chain, that will also be included. I.e.

Array.prototype.myOwnFunction = function() { alert(this); }
a = new Array();
a[0] = 'foo';
a[1] = 'bar';
for(x in a){
 document.write(x + ' = ' + a[x]);
}

This will write:

0 = foo
1 = bar
myOwnFunction = function() { alert(this); }

And since you can never be sure that nothing will be added to the prototype chain just use a for loop to enumerate the array:

for(i=0,x=a.length;i<x;i++){
 document.write(i + ' = ' + a[i]);
}

This will write:

0 = foo
1 = bar

I selected 5.6 php version, after that error cleared on my wordpress blog site...

In ES6 you can also

let [first, ...second] = str.split(" ")
second = second.join(" ")

line[5:]

gives you characters after the first five.

Use the stringify function

var j_json = JSON.stringify(j);

console.log("j in json object format :", j_json);

Happy coding!!!

I ran into the same problem, and I'm not sure why, but it turned out to be that the script link generated by Scripts.Render did not have a .js extension. Because it also does not have a Type attribute the browser was just unable to use it (chrome and firefox).

To resolve this, I changed my bundle configuration to generate compiled files with a js extension, e.g.

            var coreScripts = new ScriptBundle("~/bundles/coreAssets.js")
            .Include("~/scripts/jquery.js");

        var coreStyles = new StyleBundle("~/bundles/coreStyles.css")
            .Include("~/css/bootstrap.css");

Notice in new StyleBundle(... instead of saying ~/bundles/someBundle, I am saying ~/bundlers/someBundle.js or ~/bundles/someStyles.css..

This causes the link generated in the src attribute to have .js or .css on it when optimizations are enabled, as such the browsers know based on the file extension what mime/type to use on the get request and everything works.

If I take off the extension, everything breaks. That's because @Scripts and @Styles doesn't render all the necessary attributes to understand a src to a file with no extension.

Singleton that can't change the object after the instantiation

class User {
  final int age;
  final String name;
  
  User({
    this.name,
    this.age
    });
  
  static User _instance;
  
  static User getInstance({name, age}) {
     if(_instance == null) {
       _instance = User(name: name, age: age);
       return _instance;
     }
    return _instance;
  }
}

  print(User.getInstance(name: "baidu", age: 24).age); //24
  
  print(User.getInstance(name: "baidu 2").name); // is not changed //baidu

  print(User.getInstance()); // {name: "baidu": age 24}

I don't think there are any machine code decompilers that produce Pascal code. Most "Delphi decompilers" parse form and RTTI data, but do not actually decompile the machine code. I can only recommend using something like DeDe (or similar software) to extract symbol information in combination with a C decompiler, then translate the decompiled C code to Delphi (there are many source code converters out there).

Often data on webpages is in the form of an XML table. You can read an XML table into R using the package XML.

In this package, the function

readHTMLTable(<url>)

will look through a page for XML tables and return a list of data frames (one for each table found).

When the left part is an object instance, you use ->. Otherwise, you use ::.

This means that -> is mostly used to access instance members (though it can also be used to access static members, such usage is discouraged), while :: is usually used to access static members (though in a few special cases, it's used to access instance members).

In general, :: is used for scope resolution, and it may have either a class name, parent, self, or (in PHP 5.3) static to its left. parent refers to the scope of the superclass of the class where it's used; self refers to the scope of the class where it's used; static refers to the "called scope" (see late static bindings).

The rule is that a call with :: is an instance call if and only if:

• the target method is not declared as static and
• there is a compatible object context at the time of the call, meaning these must be true:
  1. the call is made from a context where $this exists and
  2. the class of $this is either the class of the method being called or a subclass of it.

Example:

class A {
    public function func_instance() {
        echo "in ", __METHOD__, "\n";
    }
    public function callDynamic() {
        echo "in ", __METHOD__, "\n";
        B::dyn();
    }

}

class B extends A {
    public static $prop_static = 'B::$prop_static value';
    public $prop_instance = 'B::$prop_instance value';

    public function func_instance() {
        echo "in ", __METHOD__, "\n";
        /* this is one exception where :: is required to access an
         * instance member.
         * The super implementation of func_instance is being
         * accessed here */
        parent::func_instance();
        A::func_instance(); //same as the statement above
    }

    public static function func_static() {
        echo "in ", __METHOD__, "\n";
    }

    public function __call($name, $arguments) {
        echo "in dynamic $name (__call)", "\n";
    }

    public static function __callStatic($name, $arguments) {
        echo "in dynamic $name (__callStatic)", "\n";
    }

}

echo 'B::$prop_static: ', B::$prop_static, "\n";
echo 'B::func_static(): ', B::func_static(), "\n";
$a = new A;
$b = new B;
echo '$b->prop_instance: ', $b->prop_instance, "\n";
//not recommended (static method called as instance method):
echo '$b->func_static(): ', $b->func_static(), "\n";

echo '$b->func_instance():', "\n", $b->func_instance(), "\n";

/* This is more tricky
 * in the first case, a static call is made because $this is an
 * instance of A, so B::dyn() is a method of an incompatible class
 */
echo '$a->dyn():', "\n", $a->callDynamic(), "\n";
/* in this case, an instance call is made because $this is an
 * instance of B (despite the fact we are in a method of A), so
 * B::dyn() is a method of a compatible class (namely, it's the
 * same class as the object's)
 */
echo '$b->dyn():', "\n", $b->callDynamic(), "\n";

Output:

B::$prop_static: B::$prop_static value
B::func_static(): in B::func_static

$b->prop_instance: B::$prop_instance value
$b->func_static(): in B::func_static

$b->func_instance():
in B::func_instance
in A::func_instance
in A::func_instance

$a->dyn():
in A::callDynamic
in dynamic dyn (__callStatic)

$b->dyn():
in A::callDynamic
in dynamic dyn (__call)

It's easier than the other response. There is an xml value alpha that takes double values.

android:alpha="0.0" thats invisible

android:alpha="0.5" see-through

android:alpha="1.0" full visible

That's how it works.

Note that Robert's answer is correct, and it works in sh as well. You can (portably) simplify it even further:

for i in "$@"

is equivalent to:

for i

I.e., you don't need anything!

Testing ($ is command prompt):

$ set a b "spaces here" d
$ for i; do echo "$i"; done
a
b
spaces here
d
$ for i in "$@"; do echo "$i"; done
a
b
spaces here
d

I first read about this in Unix Programming Environment by Kernighan and Pike.

In bash, help for documents this:

for NAME [in WORDS ... ;] do COMMANDS; done

If 'in WORDS ...;' is not present, then 'in "$@"' is assumed.

    long milliseconds = current_date_microseconds.time_of_day().total_milliseconds();

    pt::time_duration current_time_milliseconds = pt::milliseconds(milliseconds);

    pt::ptime current_date_milliseconds(current_date_microseconds.date(), 
                                        current_time_milliseconds);

The select may look like the following sample:

where length(asciistr(nvalue))!=length(nvalue)  
order by nvalue;

Although the question is asking "what is a workspace?", I feel that the source of confusion is the expectation that workspaces should behave more like "projects" in other editors.

So, I to help all the people landing here because of this confusion, I wanted to post the following plugin for VS Code (not mine), "Project Manager": https://marketplace.visualstudio.com/items?itemName=alefragnani.project-manager

Gotos are universally reviled in computer science and programming as they lead to very unstructured code.

Python (like almost every programming language today) supports structured programming which controls flow using if/then/else, loop and subroutines.

The key to thinking in a structured way is to understand how and why you are branching on code.

For example, lets pretend Python had a goto and corresponding label statement shudder. Look at the following code. In it if a number is greater than or equal to 0 we print if it

number = input()
if number < 0: goto negative
if number % 2 == 0:
   print "even"
else:
   print "odd"
goto end
label: negative
print "negative"
label: end
print "all done"

If we want to know when a piece of code is executed, we need to carefully traceback in the program, and examine how a label was arrived at - which is something that can't really be done.

For example, we can rewrite the above as:

number = input()
goto check

label: negative
print "negative"
goto end

label: check
if number < 0: goto negative
if number % 2 == 0:
   print "even"
else:
   print "odd"
goto end

label: end
print "all done"

Here, there are two possible ways to arrive at the "end", and we can't know which one was chosen. As programs get large this kind of problem gets worse and results in spaghetti code

In comparison, below is how you would write this program in Python:

number = input()
if number >= 0:
   if number % 2 == 0:
       print "even"
   else:
       print "odd"
else:
   print "negative"
print "all done"

I can look at a particular line of code, and know under what conditions it is met by tracing back the tree of if/then/else blocks it is in. For example, I know that the line print "odd" will be run when a ((number >= 0) == True) and ((number % 2 == 0) == False).

Instead of explaining it with words, here's an example. This is a Scheme version of the factorial function:

(define (factorial x)
  (if (= x 0) 1
      (* x (factorial (- x 1)))))

Here is a version of factorial that is tail-recursive:

(define factorial
  (letrec ((fact (lambda (x accum)
                   (if (= x 0) accum
                       (fact (- x 1) (* accum x))))))
    (lambda (x)
      (fact x 1))))

You will notice in the first version that the recursive call to fact is fed into the multiplication expression, and therefore the state has to be saved on the stack when making the recursive call. In the tail-recursive version there is no other S-expression waiting for the value of the recursive call, and since there is no further work to do, the state doesn't have to be saved on the stack. As a rule, Scheme tail-recursive functions use constant stack space.

This is very simple actually.

Please notice that I'm

I. adding name="selectedCorp" to your select opening tag, and

II. changing your [value]="corporationObj" to [value]="corporation", which is consistent with the corporation in your *ngFor="let corporation of corporations" statement:

 <form class="form-inline" (ngSubmit)="HelloCorp(f)" #f="ngForm">
   <div class="select">
     <select class="form-control col-lg-8" #corporation name="selectedCorp" required>
       <option *ngFor="let corporation of corporations" [value]="corporation">{{corporation.corp_name}}</option>
     </select>
     <button type="submit" class="btn btn-primary manage">Submit</button>
   </div>
 </form>

And then in your .ts file, you just do the following:

HelloCorp(form: NgForm) {
   const corporationObj = form.value.selectedCorp;
}

and the const corporationObj now is the selected corporation object, which will include all the properties of the corporation class you have defined.

NOTE:

In the html code, by the statement [value]="corporation", the corporation (from *ngFor="let corporation of corporations") is bound to [value], and the name property will get the value.

Since the name is "selectedCorp", you can get the actual value by getting "form.value.selectedCorp" in your .ts file.

By the way, actually you don't need the "#corporation" in your "select" opening tag.

The second example would be the one to go with, not just for readability, but because of the fact that in the first example, If NOT value1 would return a boolean value to be compared against value2. IOW, you need to rewrite that example as

If NOT (value1 = value2)

which just makes the use of the NOT keyword pointless.

Global asax events explained

Application_Init: Fired when an application initializes or is first called. It's invoked for all HttpApplication object instances.

Application_Disposed: Fired just before an application is destroyed. This is the ideal location for cleaning up previously used resources.

Application_Error: Fired when an unhandled exception is encountered within the application.

Application_Start: Fired when the first instance of the HttpApplication class is created. It allows you to create objects that are accessible by all HttpApplication instances.

Application_End: Fired when the last instance of an HttpApplication class is destroyed. It's fired only once during an application's lifetime.

Application_BeginRequest: Fired when an application request is received. It's the first event fired for a request, which is often a page request (URL) that a user enters.

Application_EndRequest: The last event fired for an application request.

Application_PreRequestHandlerExecute: Fired before the ASP.NET page framework begins executing an event handler like a page or Web service.

Application_PostRequestHandlerExecute: Fired when the ASP.NET page framework is finished executing an event handler.

Applcation_PreSendRequestHeaders: Fired before the ASP.NET page framework sends HTTP headers to a requesting client (browser).

Application_PreSendContent: Fired before the ASP.NET page framework sends content to a requesting client (browser).

Application_AcquireRequestState: Fired when the ASP.NET page framework gets the current state (Session state) related to the current request.

Application_ReleaseRequestState: Fired when the ASP.NET page framework completes execution of all event handlers. This results in all state modules to save their current state data.

Application_ResolveRequestCache: Fired when the ASP.NET page framework completes an authorization request. It allows caching modules to serve the request from the cache, thus bypassing handler execution.

Application_UpdateRequestCache: Fired when the ASP.NET page framework completes handler execution to allow caching modules to store responses to be used to handle subsequent requests.

Application_AuthenticateRequest: Fired when the security module has established the current user's identity as valid. At this point, the user's credentials have been validated.

Application_AuthorizeRequest: Fired when the security module has verified that a user can access resources.

Session_Start: Fired when a new user visits the application Web site.

Session_End: Fired when a user's session times out, ends, or they leave the application Web site.

Using naked excepts is not a good practice because you usually catch more than you bargain for.

I would suggest modifying the except to catch ONLY the exception that you would like to handle. I don't think that raising it has the desired effect, because when you go to instantiate TheThread in the outer try, if it raises an exception, the assignment is never going to happen.

Instead you might want to just alert on it and move on, such as:

def run(self):
    try:
       shul.copytree(self.sourceFolder, self.destFolder)
    except OSError, err:
       print err

Then when that exception is caught, you can handle it there. Then when the outer try catches an exception from TheThread, you know it won't be the one you already handled, and will help you isolate your process flow.

Environment.getExternalStorageDirectory().getAbsolutePath()

Gives you the full path the SDCard. You can then do normal File I/O operations using standard Java.

Here's a simple example for writing a file:

String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fileName = "myFile.txt";

// Not sure if the / is on the path or not
File f = new File(baseDir + File.separator + fileName);
f.write(...);
f.flush();
f.close();

Edit:

Oops - you wanted an example for reading ...

String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fileName = "myFile.txt";

// Not sure if the / is on the path or not
File f = new File(baseDir + File.Separator + fileName);
FileInputStream fiStream = new FileInputStream(f);

byte[] bytes;

// You might not get the whole file, lookup File I/O examples for Java
fiStream.read(bytes); 
fiStream.close();

I found this easy to remember:

mongo //to start the mongodb shell

show dbs //to list existing databases

use <dbname> //the <dbname> is the database you'd like to drop

db //should show <dbname> just to be sure I'm working with the right database

db.dropDatabase() //will delete the database & return { "dropped" : "<dbname>", "ok" : 1 }

SCRUM :

SCRUM is a type of Agile approach. It is a Framework not a Methodology.

It does not provide detailed instructions to what needs to be done rather most of it is dependent on the team that is developing the software. Because the developing the project knows how the problem can be solved that is why much is left on them

Cross-functional and self-organizing teams are essential in case of scrum. There is no team leader in this case who will assign tasks to the team members rather the whole team addresses the issues or problems. It is cross-functional in a way that everyone is involved in the project right from the idea to the implementation of the project.

The advantage of scrum is that a project’s direction to be adjusted based on completed work, not on speculation or predictions.

Roles Involved : Product Owner, Scrum Master, Team Members

Agile Methodology :

Build Software applications that are unpredictable in nature

Iterative and incremental work cadences called sprints are used in this methodology.

Both Agile and SCRUM follows the system -- some of the features are developed as a part of the sprint and at the end of each sprint; the features are completed right from coding, testing and their integration into the product. A demonstration of the functionality is provided to the owner at the end of each sprint so that feedback can be taken which can be helpful for the next sprint.

Manifesto for Agile Development :

1. Individuals and interactions over processes and tools
2. Working software over comprehensive documentation
3. Customer collaboration over contract negotiation
4. Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the left more.

One thing to notice between mercurial of bitbucket.org and git of github is, mercurial can have as many private repositories as you want, but github you have to upgrade to a paid account. So, that's why I go for bitbucket which uses mercurial.

Maybe you can script/control winscp?

Update: winscp now has a .NET library available as a nuget package that supports SFTP, SCP, and FTPS

The problem is because your file are not with the same encoding. First run the following command in all your files:

file -i filename.* 

In order to fix the problem you have to change all your files to uft-8. You can do it with the command iconv:

iconv -f fromcode -t tocode filename > newfilename

Example:

iconv -f iso-8859-1 -t utf-8 index.html > fixed/index.html

After this you can run file -i fixedx/index.html and you will see that your file is now in uft-8

Why cant we just use eval()?

def install():
    print "In install"

New method

def installWithOptions(var1, var2):
    print "In install with options " + var1 + " " + var2

And then you call the method as below

method_name1 = 'install()'
method_name2 = 'installWithOptions("a","b")'
eval(method_name1)
eval(method_name2)

This gives the output as

In install
In install with options a b

You can use animate insted of show/hide

Something like this:

function switch_tabs(obj)
{
    $('.tab-content').animate({opacity:0},3000);
    $('.tabs a').removeClass("selected");
    var id = obj.attr("rel");

    $('#'+id).animate({opacity:1},3000);
    obj.addClass("selected");
}

I call *args "star args" or "varargs" and **kwargs "keyword args".

With slight modification, the answer above works with arrays of arbitrary dimension (1d, 2d, 3d, ...):

def find_nearest(a, a0):
    "Element in nd array `a` closest to the scalar value `a0`"
    idx = np.abs(a - a0).argmin()
    return a.flat[idx]

Or, written as a single line:

a.flat[np.abs(a - a0).argmin()]

Since you have a ::1 localhost line in your hosts file, it would seem that curl is attempting to use IPv6 to contact your local web server.

Since the web server is not listening on IPv6, the connection fails.

You could try to use the --ipv4 option to curl, which should force an IPv4 connection when both are available.

The accepted answer needs a little clarification. The row will be there if CLR is enabled or disabled. Value will be 1 if enabled, or 0 if disabled.

I use this script to enable on a server, if the option is disabled:

if not exists(
    SELECT value
    FROM sys.configurations
    WHERE name = 'clr enabled'
     and value = 1
)
begin
    exec sp_configure @configname=clr_enabled, @configvalue=1
    reconfigure
end

use maven dependency

<dependency> 
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-io</artifactId> 
  <version>1.3.2</version> 
</dependency> 

or download commons-io.1.3.2.jar to your lib folder

Java has 5 different boolean compare operators: &, &&, |, ||, ^

& and && are "and" operators, | and || "or" operators, ^ is "xor"

The single ones will check every parameter, regardless of the values, before checking the values of the parameters. The double ones will first check the left parameter and its value and if true (||) or false (&&) leave the second one untouched. Sound compilcated? An easy example should make it clear:

Given for all examples:

 String aString = null;

AND:

 if (aString != null & aString.equals("lala"))

Both parameters are checked before the evaluation is done and a NullPointerException will be thrown for the second parameter.

 if (aString != null && aString.equals("lala"))

The first parameter is checked and it returns false, so the second paramter won't be checked, because the result is false anyway.

The same for OR:

 if (aString == null | !aString.equals("lala"))

Will raise NullPointerException, too.

 if (aString == null || !aString.equals("lala"))

The first parameter is checked and it returns true, so the second paramter won't be checked, because the result is true anyway.

XOR can't be optimized, because it depends on both parameters.

Sorry to reanimate a dead thread, but I have just been dealing with this myself, and after finding all sorts of crazy bloated solutions, I managed to come up with this.

[Long]$actualSize = 0
foreach ($item in (Get-ChildItem $path -recurse | Where {-not $_.PSIsContainer} | ForEach-Object {$_.FullName})) {
   $actualSize += (Get-Item $item).length
}

Quickly and in few lines of code gives me a folder size in Bytes, than can easily be converted to any units you want with / 1MB or the like. Am I missing something? Compared to this overwrought mess it seems rather simple and to the point. Not to mention that code doesn't even work since the called function is not the same name as the defined function. And has been wrong for 6 years. ;) So, any reasons NOT to use this stripped down approach?

Delete the server instance from Eclipse and create a new one.

You have a lot of variants for using @RequestParam with additional optional elements, e.g.

@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr

If you don't put required = false - param will be required by default.

defaultValue = "someValue" - the default value to use as a fallback when the request parameter is not provided or has an empty value.

If request and method param are the same - you don't need value = "someAttr"

Well that is Because of

you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception. and the one way is to encrypt that data Directly into the String.

look this. Try and u will be able to resolve this

public static String decrypt(String encryptedData) throws Exception {

    Key key = generateKey();
    Cipher c = Cipher.getInstance(ALGO);
    c.init(Cipher.DECRYPT_MODE, key);
    String decordedValue = new BASE64Decoder().decodeBuffer(encryptedData).toString().trim();
    System.out.println("This is Data to be Decrypted" + decordedValue);
    return decordedValue;
}

hope that will help.

gdb has --init-command <somefile> where somefile has a list of gdb commands to run, I use this to have //GDB comments in my code, then `

echo "file ./a.out" > run
grep -nrIH "//GDB"|
    sed "s/\(^[^:]\+:[^:]\+\):.*$/\1/g" |
    awk '{print "b" " " $1}'|
    grep -v $(echo $0|sed "s/.*\///g") >> run
gdb --init-command ./run -ex=r

as a script, which puts the command to load the debug symbols, and then generates a list of break commands to put a break point for each //GDB comment, and starts it running

The most libraries offer escaping everything they can, including hundreds of symbols and thousands of non-ASCII characters which is not what you want in UTF-8 world.

Also, as Jeff Williams noted, there's no single “escape HTML” option, there are several contexts.

Assuming you never use unquoted attributes, and keeping in mind that different contexts exist, it've written my own version:

private static final long BODY_ESCAPE =
        1L << '&' | 1L << '<' | 1L << '>';
private static final long DOUBLE_QUOTED_ATTR_ESCAPE =
        1L << '"' | 1L << '&' | 1L << '<' | 1L << '>';
private static final long SINGLE_QUOTED_ATTR_ESCAPE =
        1L << '"' | 1L << '&' | 1L << '\'' | 1L << '<' | 1L << '>';

// 'quot' and 'apos' are 1 char longer than '#34' and '#39' which I've decided to use
private static final String REPLACEMENTS = "&#34;&amp;&#39;&lt;&gt;";
private static final int REPL_SLICES = /*  |0,   5,   10,  15, 19, 23*/
        5<<5 | 10<<10 | 15<<15 | 19<<20 | 23<<25;
// These 5-bit numbers packed into a single int
// are indices within REPLACEMENTS which is a 'flat' String[]

private static void appendEscaped(
        StringBuilder builder,
        CharSequence content,
        long escapes // pass BODY_ESCAPE or *_QUOTED_ATTR_ESCAPE here
) {
    int startIdx = 0, len = content.length();
    for (int i = 0; i < len; i++) {
        char c = content.charAt(i);
        long one;
        if (((c & 63) == c) && ((one = 1L << c) & escapes) != 0) {
        // -^^^^^^^^^^^^^^^   -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        // |                  | take only dangerous characters
        // | java shifts longs by 6 least significant bits,
        // | e. g. << 0b110111111 is same as >> 0b111111.
        // | Filter out bigger characters

            int index = Long.bitCount(SINGLE_QUOTED_ATTR_ESCAPE & (one - 1));
            builder.append(content, startIdx, i /* exclusive */)
                    .append(REPLACEMENTS,
                            REPL_SLICES >>> 5*index & 31,
                            REPL_SLICES >>> 5*(index+1) & 31);
            startIdx = i + 1;
        }
    }
    builder.append(content, startIdx, len);
}

I would like to add that if you only have Python3 on your system then you need to start using pip3 instead of pip.

You can install pip3 using the following command;

sudo apt install python3-pip -y

After this you can try to install the package you need with;

sudo pip3 install <package>

XML-XIG: XML Instance Generator

http://xml-xig.sourceforge.net/

This opensource would be helpful.

java.util.Date.from(localDate.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant());

Since PHP 5.1.0, file_put_contents() supports writing piece-by-piece by passing a stream-handle as the $data parameter:

file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));

From the manual:

If data [that is the second argument] is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using stream_copy_to_stream().

(Thanks Hakre.)

More recent answer in the case you want to delete every entries in every tables:

def reset
    Rails.application.eager_load!
    ActiveRecord::Base.descendants.each { |c| c.delete_all unless c == ActiveRecord::SchemaMigration  }
end

More information about the eager_load here.

After calling it, we can access to all of the descendants of ActiveRecord::Base and we can apply a delete_all on all the models.

Note that we make sure not to clear the SchemaMigration table.

You want to use sections when you want a bit of code/content to render in a placeholder that has been defined in a layout page.

In the specific example you linked, he has defined the RenderSection in the _Layout.cshtml. Any view that uses that layout can define an @section of the same name as defined in Layout, and it will replace the RenderSection call in the layout.

Perhaps you're wondering how we know Index.cshtml uses that layout? This is due to a bit of MVC/Razor convention. If you look at the dialog where he is adding the view, the box "Use layout or master page" is checked, and just below that it says "Leave empty if it is set in a Razor _viewstart file". It isn't shown, but inside that _ViewStart.cshtml file is code like:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

The way viewstarts work is that any cshtml file within the same directory or child directories will run the ViewStart before it runs itself.

Which is what tells us that Index.cshtml uses Shared/_Layout.cshtml.

I think you mean to update it back to the OLD password, when the NEW one is not supplied.

DROP TRIGGER IF EXISTS upd_user;

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '') THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

However, this means a user can never blank out a password.

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '' OR NEW.password = OLD.password) THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

To use the class ActionBarOverlayLayout you need to include this in the dependencies section of build.gradle file:

compile 'com.android.support:design:24.1.1'

Sync the project once again and then you will find no problem

Run nohup python bgservice.py & to get the script to ignore the hangup signal and keep running. Output will be put in nohup.out.

Ideally, you'd run your script with something like supervise so that it can be restarted if (when) it dies.

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

Note for the answer-seekers (who I also was) - if using arc is not obligatory, a far simpler solution to draw a part-circle is to use stroke-dasharray of SVG <circle>.

Divide dash array into two elements, and scale their range to the desired angle. Starting angle can be adjusted using stroke-dashoffset.

Not a single cosine in sight.

I suspect you want to check that it's after 11pm or before 7am:

select *
from MyTable
where CAST(Created as time) >= '23:00:00' 
   or CAST(Created as time) < '07:00:00'

I ran into the same problem.

In most scenarios using the hack-ish setTimeout(() => { }, 0) in componentDidMount() worked.

But not in a special case; and I didn't want to use the ReachDOM findDOMNode since the documentation says:

Note: findDOMNode is an escape hatch used to access the underlying DOM node. In most cases, use of this escape hatch is discouraged because it pierces the component abstraction.

(Source: findDOMNode)

So in that particular component I had to use the componentDidUpdate() event, so my code ended up being like this:

componentDidMount() {
    // feel this a little hacky? check this: http://stackoverflow.com/questions/26556436/react-after-render-code
    setTimeout(() => {
       window.addEventListener("resize", this.updateDimensions.bind(this));
       this.updateDimensions();
    }, 0);
}

And then:

componentDidUpdate() {
    this.updateDimensions();
}

Finally, in my case, I had to remove the listener created in componentDidMount:

componentWillUnmount() {
    window.removeEventListener("resize", this.updateDimensions.bind(this));
}

I run MariaDB (MySQL compatible) on two machines locally. I'm not sure what prompted the error and nothing I tried worked. So I stopped the service, deleted everything in MariaDB's directory (except the data directory) and copied the files from my secondary machine and everything is working well enough as far as I can tell.

For a live server it'd be a bit different and a super-guru might be able to add an insight comment (e.g. something outside of the data directory might have something to do with preventing data corruption or indexes in example?). I would just stop the service and copy the entire directory once every month or so and then start the service again.

I came across this post looking for a "shaking" implementation. millenomi's answer worked well for me, although i was looking for something that required a bit more "shaking action" to trigger. I've replaced to Boolean value with an int shakeCount. I also reimplemented the L0AccelerationIsShaking() method in Objective-C. You can tweak the ammount of shaking required by tweaking the ammount added to shakeCount. I'm not sure i've found the optimal values yet, but it seems to be working well so far. Hope this helps someone:

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
    if (self.lastAcceleration) {
        if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7] && shakeCount >= 9) {
            //Shaking here, DO stuff.
            shakeCount = 0;
        } else if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7]) {
            shakeCount = shakeCount + 5;
        }else if (![self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.2]) {
            if (shakeCount > 0) {
                shakeCount--;
            }
        }
    }
    self.lastAcceleration = acceleration;
}

- (BOOL) AccelerationIsShakingLast:(UIAcceleration *)last current:(UIAcceleration *)current threshold:(double)threshold {
    double
    deltaX = fabs(last.x - current.x),
    deltaY = fabs(last.y - current.y),
    deltaZ = fabs(last.z - current.z);

    return
    (deltaX > threshold && deltaY > threshold) ||
    (deltaX > threshold && deltaZ > threshold) ||
    (deltaY > threshold && deltaZ > threshold);
}

PS: I've set the update interval to 1/15th of a second.

[[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0 / 15)];

Angular 2.0.0 Final:

I have found that using a ViewChild setter is most reliable way to set the initial form control focus:

@ViewChild("myInput")
set myInput(_input: ElementRef | undefined) {
    if (_input !== undefined) {
        setTimeout(() => {
            this._renderer.invokeElementMethod(_input.nativeElement, "focus");
        }, 0);
    }
}

The setter is first called with an undefined value followed by a call with an initialized ElementRef.

Working example and full source here: http://plnkr.co/edit/u0sLLi?p=preview

Using TypeScript 2.0.3 Final/RTM, Angular 2.0.0 Final/RTM, and Chrome 53.0.2785.116 m (64-bit).

UPDATE for Angular 4+

Renderer has been deprecated in favor of Renderer2, but Renderer2 does not have the invokeElementMethod. You will need to access the DOM directly to set the focus as in input.nativeElement.focus().

I'm still finding that the ViewChild setter approach works best. When using AfterViewInit I sometimes get read property 'nativeElement' of undefined error.

@ViewChild("myInput")
set myInput(_input: ElementRef | undefined) {
    if (_input !== undefined) {
        setTimeout(() => { //This setTimeout call may not be necessary anymore.
            _input.nativeElement.focus();
        }, 0);
    }
}

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

Compile this app.

#include <iostream>
#include <cstring>

int main()
{
  char str[1000];
  memset(str, '\n', 999);
  str[999] = 0;
  std::cout << str << std::endl;
  return 0;
}

This is known as a Shebang:

http://en.wikipedia.org/wiki/Shebang_(Unix)

#!interpreter [optional-arg]

A shebang is only relevant when a script has the execute permission (e.g. chmod u+x script.sh).

When a shell executes the script it will use the specified interpreter.

Example:

#!/bin/bash
# file: foo.sh
echo 1

$ chmod u+x foo.sh
$ ./foo.sh
  1

If you are using the Postgres Mac app (by Heroku) and Bundler, you can add the pg_config directly inside the app, to your bundle.

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

...then run bundle again.

Note: check the version first using the following.

ls /Applications/Postgres.app/Contents/Versions/

mkdirs() also creates parent directories in the path this File represents.

javadocs for mkdirs():

Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.

javadocs for mkdir():

Creates the directory named by this abstract pathname.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

will yield false for the first [and no dir will be created], and true for the second, and you will have created non_existing_dir/someDir

Parameters are key-value pairs that can appear inside URL path, and start with a semicolon character (;).

Query string appears after the path (if any) and starts with a question mark character (?).

Both parameters and query string contain key-value pairs.

In a GET request, parameters appear in the URL itself:

<scheme>://<username>:<password>@<host>:<port>/<path>;<parameters>?<query>#<fragment>

In a POST request, parameters can appear in the URL itself, but also in the datastream (as known as content).

Query string is always a part of the URL.

Parameters can be buried in form-data datastream when using POST method so they may not appear in the URL. Yes a POST request can define parameters as form data and in the URL, and this is not inconsistent because parameters can have several values.

I've found no explaination for this behavior so far. I guess it might be useful sometimes to "unhide" parameters from a POST request, or even let the code handling a GET request share some parts with the code handling a POST. Of course this can work only with server code supporting parameters in a URL.

Until you get better insights, I suggest you to use parameters only in form-data datastream of POST requests.

What Every Developer Should Know About URLs

RFC 3986

This works for me: \newcommand{\variablename}{the text}

For eg: \newcommand\m{100}

So when you type " \m\ is my mark " in the source code,

the pdf output displays as :

100 is my mark

This is a good reference, it helped me switch my http requests to httpClient.

It compares the two in terms of differences and gives code examples.

This is just a few differences I dealt with while changing services to httpclient in my project (borrowing from the article I mentioned) :

Importing

import {HttpModule} from '@angular/http';
import {HttpClientModule} from '@angular/common/http';

Requesting and parsing response:

@angular/http

 this.http.get(url)
      // Extract the data in HTTP Response (parsing)
      .map((response: Response) => response.json() as GithubUser)
      .subscribe((data: GithubUser) => {
        // Display the result
        console.log('TJ user data', data);
      });

@angular/common/http

 this.http.get(url)
      .subscribe((data: GithubUser) => {
        // Data extraction from the HTTP response is already done
        // Display the result
        console.log('TJ user data', data);
      });

Note: You no longer have to extract the returned data explicitly; by default, if the data you get back is type of JSON, then you don't have to do anything extra.

But, if you need to parse any other type of response like text or blob, then make sure you add the responseType in the request. Like so:

Making the GET HTTP request with responseType option:

 this.http.get(url, {responseType: 'blob'})
      .subscribe((data) => {
        // Data extraction from the HTTP response is already done
        // Display the result
        console.log('TJ user data', data);
      });

Adding Interceptor

I also used interceptors for adding the token for my authorization to every request, reference.

like so:

@Injectable()
export class MyFirstInterceptor implements HttpInterceptor {

    constructor(private currentUserService: CurrentUserService) { }

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

        // get the token from a service
        const token: string = this.currentUserService.token;

        // add it if we have one
        if (token) {
            req = req.clone({ headers: req.headers.set('Authorization', 'Bearer ' + token) });
        }

        // if this is a login-request the header is 
        // already set to x/www/formurl/encoded. 
        // so if we already have a content-type, do not 
        // set it, but if we don't have one, set it to 
        // default --> json
        if (!req.headers.has('Content-Type')) {
            req = req.clone({ headers: req.headers.set('Content-Type', 'application/json') });
        }

        // setting the accept header
        req = req.clone({ headers: req.headers.set('Accept', 'application/json') });
        return next.handle(req);
    }
}

Its a pretty nice upgrade!

Per the docs, replace returns the new string - it does not modify the string you pass it.

var tt="88,9827";
tt = tt.replace(/,/g, '.');
^^^^
alert(tt);

I just went through the learning process myself. I figured it out, but I agree the documentation is written in a way that was sorta intimidating to me. The big "aha" moment for me was understanding that for browsing, all CKeditor does is open a new window and provide a few parameters in the url. It allows you to add additional parameters but be advised you will need to use encodeURIComponent() on your values.

I call the browser and the uploader with

CKEDITOR.replace( 'body',  
{  
    filebrowserBrowseUrl: 'browse.php?type=Images&dir=' +  
        encodeURIComponent('content/images'),  
    filebrowserUploadUrl: 'upload.php?type=Files&dir=' +  
        encodeURIComponent('content/images')  
}

For the browser, in the open window (browse.php) you use php & js to supply a list of choices and then upon your supplied onclick handler, you call a CKeditor function with two arguments, the url/path to the selected image and CKEditorFuncNum supplied by CKeditor in the url:

function myOnclickHandler(){  
//..    
    window.opener.CKEDITOR.tools.callFunction(<?php echo $_GET['CKEditorFuncNum']; ?>, pathToImage);  
    window.close();
}       

Simarly, the uploader simply calls the url you supply, e.g., upload.php, and again supplies $_GET['CKEditorFuncNum']. The target is an iframe so, after you save the file from $_FILES you pass your feedback to CKeditor as thus:

$funcNum = $_GET['CKEditorFuncNum'];  
exit("<script>window.parent.CKEDITOR.tools.callFunction($funcNum, '$filePath', '$errorMessage');</script>");  

Below is a simple to understand custom browser script. While it does not allow users to navigate around in the server, it does allow you to indicate which directory to pull image files from when calling the browser.

It's all rather basic coding so it should work in all relatively modern browsers.

CKeditor merely opens a new window with the url provided

/*          
    in CKeditor **use encodeURIComponent()** to add dir param to the filebrowserBrowseUrl property

    Replace content/images with directory where your images are housed.
*/          
        CKEDITOR.replace( 'editor1', {  
            filebrowserBrowseUrl: '**browse.php**?type=Images&dir=' + encodeURIComponent('content/images'),  
            filebrowserUploadUrl: 'upload.php?type=Files&dir=' + encodeURIComponent('content/images') 
        });

I have tried to create an image to explain this in the most simple words

1) Authentication means "Are you who you say you are?"

2) Authorization means "Should you be able to do what you are trying to do?".

This is also described in the image below.

I have tried to explain it in the best terms possible, and created an image of the same.

Probably your simple json.jar file isn't in your classpath.

Of course, the proper way to write a Makefile is to actually document which targets depend on which sources. In the trivial case, the proposed solution will make foo depend on itself, but of course, make is smart enough to drop a circular dependency. But if you add a temporary file to your directory, it will "magically" become part of the dependency chain. Better to create an explicit list of dependencies once and for all, perhaps via a script.

GNU make knows how to run gcc to produce an executable out of a set of .c and .h files, so maybe all you really need amounts to

foo: $(wildcard *.h) $(wildcard *.c)

What is a smart pointer.

Long version, In principle:

https://web.stanford.edu/class/archive/cs/cs106l/cs106l.1192/lectures/lecture15/15_RAII.pdf

A modern C++ idiom:

RAII: Resource Acquisition Is Initialization.

? When you initialize an object, it should already have 
  acquired any resources it needs (in the constructor).


? When an object goes out of scope, it should release every 
  resource it is using (using the destructor).

key point:

? There should never be a half-ready or half-dead object.
? When an object is created, it should be in a ready state.
? When an object goes out of scope, it should release its resources. 
? The user shouldn’t have to do anything more. 

Raw Pointers violate RAII: It need user to delete manually when the pointers go out of scope.

RAII solution is:

Have a smart pointer class:
? Allocates the memory when initialized
? Frees the memory when destructor is called
? Allows access to underlying pointer

For smart pointer need copy and share, use shared_ptr:

? use another memory to store Reference counting and shared.
? increment when copy, decrement when destructor.
? delete memory when Reference counting is 0. 
  also delete memory that store Reference counting.

for smart pointer not own the raw pointer, use weak_ptr:

? not change Reference counting.

shared_ptr usage:

correct way:
std::shared_ptr<T> t1 = std::make_shared<T>(TArgs);
std::shared_ptr<T> t2 = std::shared_ptr<T>(new T(Targs));

wrong way:
T* pt = new T(TArgs); // never exposure the raw pointer
shared_ptr<T> t1 = shared_ptr<T>(pt);
shared_ptr<T> t2 = shared_ptr<T>(pt);

Always avoid using raw pointer.

For scenario that have to use raw pointer:

https://stackoverflow.com/a/19432062/2482283

For raw pointer that not nullptr, use reference instead.

not use T*
use T&  

For optional reference which maybe nullptr, use raw pointer, and which means:

T* pt; is optional reference and maybe nullptr.
Not own the raw pointer, 
Raw pointer is managed by some one else.
I only know that the caller is sure it is not released now.

I have also used following link as others have suggested you for bluetooth communication.

http://developer.android.com/guide/topics/connectivity/bluetooth.html

The thing is all you need is a class BluetoothChatService.java

this class has following threads:

1. Accept
2. Connecting
3. Connected

Now when you call start function of the BluetoothChatService like:

mChatService.start();

It starts accept thread which means it will start looking for connection.

Now when you call

mChatService.connect(<deviceObject>,false/true);

Here first argument is device object that you can get from paired devices list or when you scan for devices you will get all the devices in range you can pass that object to this function and 2nd argument is a boolean to make secure or insecure connection.

connect function will start connecting thread which will look for any device which is running accept thread.

When such a device is found both accept thread and connecting thread will call connected function in BluetoothChatService:

connected(mmSocket, mmDevice, mSocketType);

this method starts connected thread in both the devices: Using this socket object connected thread obtains the input and output stream to the other device. And calls read function on inputstream in a while loop so that it's always trying read from other device so that whenever other device send a message this read function returns that message.

BluetoothChatService also has a write method which takes byte[] as input and calls write method on connected thread.

mChatService.write("your message".getByte());

write method in connected thread just write this byte data to outputsream of the other device.

public void write(byte[] buffer) {
   try {
       mmOutStream.write(buffer);
    // Share the sent message back to the UI Activity
    // mHandler.obtainMessage(
    // BluetoothGameSetupActivity.MESSAGE_WRITE, -1, -1,
    // buffer).sendToTarget();
    } catch (IOException e) {
    Log.e(TAG, "Exception during write", e);
     }
}

Now to communicate between two devices just call write function on mChatService and handle the message that you will receive on the other device.

If you get an "always true/fails" warning you may need to cast to Any before using is

(foo as Any) is SomeClass

It should be:

cursor.execute ("""
   UPDATE tblTableName
   SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
   WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))

You can also do it with basic string manipulation,

cursor.execute ("UPDATE tblTableName SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s WHERE Server='%s' " % (Year, Month, Day, Hour, Minute, ServerID))

but this way is discouraged because it leaves you open for SQL Injection. As it's so easy (and similar) to do it the right way^tm. Do it correctly.

The only thing you should be careful, is that some database backends don't follow the same convention for string replacement (SQLite comes to mind).

import codecs
f=codecs.open("test.html", 'r')
print f.read()

Try something like this.

If the row contains some leading (or trailing) th tags before the td you should use the :first-of-type and the :last-of-type selectors. Otherwise the first td won't be selected if it's not the first element of the row.

This gives:

td:first-of-type, td:last-of-type {
    /* styles */
}

This is from "python xml parse".

On Angular to update a component including its template, there is a straight forward solution to this, having an @Input property on your ChildComponent and add to your @Component decorator changeDetection: ChangeDetectionStrategy.OnPush as follows:

import { ChangeDetectionStrategy } from '@angular/core';

@Component({
    selector: 'master',
    templateUrl: templateUrl,
    styleUrls:[styleUrl1],
    changeDetection: ChangeDetectionStrategy.OnPush    
})

export class ChildComponent{
  @Input() data: MyData;
}

This will do all the work of check if Input data have changed and re-render the component

There are some classes in the Java platform libraries that do extend an instantiable class and add a value component. For example, java.sql.Timestamp extends java.util.Date and adds a nanoseconds field. The equals implementation for Timestamp does violate symmetry and can cause erratic behavior if Timestamp and Date objects are used in the same collection or are otherwise intermixed. The Timestamp class has a disclaimer cautioning programmers against mixing dates and timestamps. While you won’t get into trouble as long as you keep them separate, there’s nothing to prevent you from mixing them, and the resulting errors can be hard to debug. This behavior of the Timestamp class was a mistake and should not be emulated.

I also had the problem i just installed but forgot to jump the created project folder. So you need to jump your project folder.

cd project_name

and then serve php artisan command

if only 1 row, you can use join

Select t1.Col1, t1.Col2, t1.Col3, t2.Col4, t2.Col5 from Table1 t1 join Table2 t2;

I did it this way with Bootstrap 4.3.1:

<div class="d-flex vh-100">
  <div class="d-flex w-100 justify-content-center align-self-center">
    I'm in the middle
  </div>
</div>

Nullable type can invoke runtime error. So I think it's good to use a compiler option --strictNullChecks and declare number | null as type. also in case of nested function, although input type is null, compiler can not know what it could break, so I recommend use !(exclamination mark).

function broken(name: string | null): string {
  function postfix(epithet: string) {
    return name.charAt(0) + '.  the ' + epithet; // error, 'name' is possibly null
  }
  name = name || "Bob";
  return postfix("great");
}

function fixed(name: string | null): string {
  function postfix(epithet: string) {
    return name!.charAt(0) + '.  the ' + epithet; // ok
  }
  name = name || "Bob";
  return postfix("great");
}

I was looking for a different answer for the question title, so maybe other people will be too.

To set type as an ObjectId (so you may reference author as the author of book, for example), you may do like:

const Book = mongoose.model('Book', {
  author: {
    type: mongoose.Schema.Types.ObjectId, // here you set the author ID
                                          // from the Author colection, 
                                          // so you can reference it
    required: true
  },
  title: {
    type: String,
    required: true
  }
});

jQuery 1.9 is released and there does not appear to be a fix. Attempting to prevent focus of the first text box by some of the suggested methods is not working in 1.9. I think beccause the methods attempt to blur focus or move focus occur AFTER the text box in the dialog has already gained focus and done its dirty work.

I can't see anything in the API documentation that makes me think that anything has changed in terms of expected functionality. Off to add an opener button...

This also works:

db.getCollection('collectionName').find({'arrayName': {$elemMatch:{}}})

foreach() {
    $i++;
    if(index($key) == $i){}
    //
}

Your code would have worked if it had been in this format: YYYY-MM-DD, this is the computer standard for date formats http://en.wikipedia.org/wiki/ISO_8601

There's a few ways to do it.

• sys.stdin is a file-like object on which you can call functions read or readlines if you want to read everything or you want to read everything and split it by newline automatically. (You need to import sys for this to work.)

• If you want to prompt the user for input, you can use raw_input in Python 2.X, and just input in Python 3.

• If you actually just want to read command-line options, you can access them via the sys.argv list.

You will probably find this Wikibook article on I/O in Python to be a useful reference as well.

Do not forget to verify if your text editor encodes properly your code in UTF-8.

Otherwise, you may have invisible characters that are not interpreted as UTF-8.

Open Ports Scanner works for me.

In my case, I have reinstalled ubuntu and the user name is changed from previous. In this case the the generated ssh key also differs from the previous one.

The issue solved by just copy the current ssh public key, in the repository. The key will be available in your user's /home/.ssh/id_rsa.pub

if you are trying to write a pandas dataframe into a file using a json format i'd recommend this

destination='filepath'
saveFile = open(destination, 'w')
saveFile.write(df.to_json())
saveFile.close()

There is a relatively new library which is very promising and albeit still poorly documented, seems very clean and pythonic: python zeep.

One interesting thing is multiple order by:

according to laravel docs:

DB::table('users')
   ->orderBy('priority', 'desc')
   ->orderBy('email', 'asc')
   ->get();

this means laravel will sort result based on priority attribute. when it's done, it will order result with same priority based on email internally.

//Fields
String myID;
int myversion = 0;


myversion = Integer.valueOf(android.os.Build.VERSION.SDK);
if (myversion < 23) {
        TelephonyManager mngr = (TelephonyManager) 
getSystemService(Context.TELEPHONY_SERVICE);
        myID= mngr.getDeviceId();
    }
    else
    {
        myID = 
Settings.Secure.getString(getApplicationContext().getContentResolver(), 
Settings.Secure.ANDROID_ID);
    }

Yes, Secure.ANDROID_ID is unique for each device.

To hide the arrow:

input::-webkit-calendar-picker-indicator{
    display: none;
}

And to hide the prompt:

input[type="date"]::-webkit-input-placeholder{ 
    visibility: hidden !important;
}

Here is a method you can use:

    public static void RemoveAllByValue<K, V>(this Dictionary<K, V> dictionary, V value)
    {
        foreach (var key in dictionary.Where(
                kvp => EqualityComparer<V>.Default.Equals(kvp.Value, value)).
                Select(x => x.Key).ToArray())
            dictionary.Remove(key);
    }

I had a similar problem, I needed the index of the item but it had to be case insensitive, i looked around the web for a few minutes and found nothing, so I just wrote a small method to get it done, here is what I did:

private static int getCaseInvariantIndex(List<string> ItemsList, string searchItem)
{
    List<string> lowercaselist = new List<string>();

    foreach (string item in ItemsList)
    {
        lowercaselist.Add(item.ToLower());
    }

    return lowercaselist.IndexOf(searchItem.ToLower());
}

Add this code to the same file, and call it like this:

int index = getCaseInvariantIndexFromList(ListOfItems, itemToFind);

Hope this helps, good luck!

Why not store it as an array of prices instead of object?

prices = []
$(allProducts).each(function () {
    var price = parseFloat($(this).data('price'));
    prices.push(price);
});
prices.sort(function(a, b) { return a - b }); //this is the magic line which sort the array

That way you can just

prices[0]; // cheapest
prices[prices.length - 1]; // most expensive

Note that you can do shift() and pop() to get min and max price respectively, but it will take off the price from the array.

Even better alternative is to use Sergei solution below, by using Math.max and min respectively.

EDIT:

I realized that this would be wrong if you have something like [11.5, 3.1, 3.5, 3.7] as 11.5 is treated as a string, and would come before the 3.x in dictionary order, you need to pass in custom sort function to make sure they are indeed treated as float:

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

Thank you, user374559 and reneD -- that code and description is very helpful.

You haven't defined struct stasher_file by your first definition. What you have defined is an nameless struct type and a variable stasher_file of that type. Since there's no definition for such type as struct stasher_file in your code, the compiler complains about incomplete type.

In order to define struct stasher_file, you should have done it as follows

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

Note where the stasher_file name is placed in the definition.

you haven't loaded driver into memory. use this following in init()

Class.forName("com.mysql.jdbc.Driver");

Also, you missed a colon (:) in url, use this

String mySqlUrl = "jdbc:mysql://localhost:3306/mysql";

Why one want to use it ?

To reduce the memory of the structure

Why one should not use it ?

1. This may lead to performance penalty, because some system works better on aligned data
2. Some machine will fail to read unaligned data
3. Code is not portable

Add below in app gradle file implementation project(path: ':project name')

If you have notepad++ installed in your pc, then you can copy text as RTF (Rich Text Format) and paste it in your outlook mail.

1) Paste you code snippet into notepad++

2) From Menu bar navigate to "Plugins -> NppExport -> Copy RTF to clipboard"

3) Paste into your email

4) Done

I recently had the same problem and used the solution provided by Harry Joy. That solution only works with with zero-based enumaration though. I also wouldn't consider it save as it doesn't deal with indexes that are out of range.

The solution I ended up using might not be as simple but it's completely save and won't hurt the performance of your code even with big enums:

public enum Example {

    UNKNOWN(0, "unknown"), ENUM1(1, "enum1"), ENUM2(2, "enum2"), ENUM3(3, "enum3");

    private static HashMap<Integer, Example> enumById = new HashMap<>();
    static {
        Arrays.stream(values()).forEach(e -> enumById.put(e.getId(), e));
    }

    public static Example getById(int id) {
        return enumById.getOrDefault(id, UNKNOWN);
    }

    private int id;
    private String description;

    private Example(int id, String description) {
        this.id = id;
        this.description= description;
    }

    public String getDescription() {
        return description;
    }

    public int getId() {
        return id;
    }
}

If you are sure that you will never be out of range with your index and you don't want to use UNKNOWN like I did above you can of course also do:

public static Example getById(int id) {
        return enumById.get(id);
}

display:none will hide the element and collapse the space is was taking up, whereas visibility:hidden will hide the element and preserve the elements space. display:none also effects some of the properties available from javascript in older versions of IE and Safari.

I know this is well after the OP. One way you can go with that keeps the table storing the zipcode data as an unsigned INT but displayed with zeros is as follows.

select LPAD(cast(zipcode_int as char), 5, '0') as zipcode from table;

While this preserves the original data as INT and can save some space in storage you will be having the server perform the INT to CHAR conversion for you. This can be thrown into a view and the person who needs this data can be directed there vs the table itself.

Considering Rails 3:

html_safe actually "sets the string" as HTML Safe (it's a little more complicated than that, but it's basically it). This way, you can return HTML Safe strings from helpers or models at will.

h can only be used from within a controller or view, since it's from a helper. It will force the output to be escaped. It's not really deprecated, but you most likely won't use it anymore: the only usage is to "revert" an html_safe declaration, pretty unusual.

Prepending your expression with raw is actually equivalent to calling to_s chained with html_safe on it, but is declared on a helper, just like h, so it can only be used on controllers and views.

"SafeBuffers and Rails 3.0" is a nice explanation on how the SafeBuffers (the class that does the html_safe magic) work.

I agree the above approved answer. But usually I use $results->isNotEmpty() method as given below.

if($results->isNotEmpty())
{
//do something
}

It's more verbose than if(!results->isEmpty()) because sometimes we forget to add '!' in front which may result in unwanted error.

Note that this method exists from version 5.3 onwards.

Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.

<a href="Controller/ActionMethod">
    <input type="button" value="Click Me" />
</a>

Adding parameters:

<a href="Controller/ActionMethod?userName=ted">
    <input type="button" value="Click Me" />
</a>

Adding parameters from a non-enumerated Model:

<a href="Controller/[email protected]">
    <input type="button" value="Click Me" />
</a>

You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!

   /* 1 */ Foo* foo1 = new Foo ();

Creates an object of type Foo in dynamic memory. foo1 points to it. Normally, you wouldn't use raw pointers in C++, but rather a smart pointer. If Foo was a POD-type, this would perform value-initialization (it doesn't apply here).

   /* 2 */ Foo* foo2 = new Foo;

Identical to before, because Foo is not a POD type.

   /* 3 */ Foo foo3;

Creates a Foo object called foo3 in automatic storage.

   /* 4 */ Foo foo4 = Foo::Foo();

Uses copy-initialization to create a Foo object called foo4 in automatic storage.

   /* 5 */ Bar* bar1 = new Bar ( *new Foo() );

Uses Bar's conversion constructor to create an object of type Bar in dynamic storage. bar1 is a pointer to it.

   /* 6 */ Bar* bar2 = new Bar ( *new Foo );

Same as before.

   /* 7 */ Bar* bar3 = new Bar ( Foo foo5 );

This is just invalid syntax. You can't declare a variable there.

   /* 8 */ Bar* bar3 = new Bar ( Foo::Foo() );

Would work and work by the same principle to 5 and 6 if bar3 wasn't declared on in 7.

5 & 6 contain memory leaks.

Syntax like new Bar ( Foo::Foo() ); is not usual. It's usually new Bar ( (Foo()) ); - extra parenthesis account for most-vexing parse. (corrected)

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

There are other differences. For instance, {'time': datetime.now()} cannot be serialized to JSON, but can be converted to string. You should use one of these tools depending on the purpose (i.e. will the result later be decoded).

You can use relative positioning to overlap your elements. However, the space they would normally occupy will still be reserved for the element:

<div style="background-color:#f00;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>
<div style="background-color:#0f0;width:200px;height:100px;position:relative;top:-50px;left:50px;">
    RELATIVE POSITIONED
</div>
<div style="background-color:#00f;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>

In the example above, there will be a block of white space between the two 'DEFAULT POSITIONED' elements. This is caused, because the 'RELATIVE POSITIONED' element still has it's space reserved.

If you use absolute positioning, your elements will not have any space reserved, so your element will actually overlap, without breaking your document:

<div style="background-color:#f00;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>
<div style="background-color:#0f0;width:200px;height:100px;position:absolute;top:50px;left:50px;">
    ABSOLUTE POSITIONED
</div>
<div style="background-color:#00f;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>

Finally, you can control which elements are on top of the others by using z-index:

<div style="z-index:10;background-color:#f00;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>
<div style="z-index:5;background-color:#0f0;width:200px;height:100px;position:absolute;top:50px;left:50px;">
    ABSOLUTE POSITIONED
</div>
<div style="z-index:0;background-color:#00f;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>

This data is JSON! You can deserialize it using the built-in json module if you're on Python 2.6+, otherwise you can use the excellent third-party simplejson module.

import json    # or `import simplejson as json` if on Python < 2.6

json_string = u'{ "id":"123456789", ... }'
obj = json.loads(json_string)    # obj now contains a dict of the data

The best way to achieve what you want is to create your own wpf based control , or use a one that was made by other people
why ? because there will be a noticeable performance impact when using the winforms dialog in a wpf application (for some reason)
i recommend this project
https://opendialog.codeplex.com/
or Nuget :

PM> Install-Package OpenDialog

it's very MVVM friendly and it isn't wraping the winforms dialog

overflow-x: hidden;
would hide any thing on the x-axis that goes outside of the element, so there would be no need for the horizontal scrollbar and it get removed.

overflow-y: hidden;
would hide any thing on the y-axis that goes outside of the element, so there would be no need for the vertical scrollbar and it get removed.

overflow: hidden;
would remove both scrollbars

I had the same question and i solved it with that:

Boolean use_vote = o.get('uses_votes').equals("1") ? true : false;

you might also consider avoiding the core PHP module altogether.

It is quite common to use the guzzle json tools as a library in PHP apps these days. If your app is a composer app, it is trivial to include them as a part of a composer build. The guzzle tool, as a library, would be a turnkey replacement for the json tool, if you tell PHP to autoinclude the tool.

First list all the stashes

git stash list

?

stash@{0}: WIP on Produktkonfigurator: 132c06a5 Cursor bei glyphicon plus und close zu zeigende Hand ändern
stash@{1}: WIP on Produktkonfigurator: 132c06a5 Cursor bei glyphicon plus und close zu zeigende Hand ändern
stash@{2}: WIP on master: 7e450c81 Merge branch 'Offlineseite'

Then show which files are in the stash (lets pick stash 1):

git stash show 1 --name-only

//Hint: you can also write
//git stash show stash@{1} --name-only

?

 ajax/product.php
 ajax/productPrice.php
 errors/Company/js/offlineMain.phtml
 errors/Company/mage.php
 errors/Company/page.phtml
 js/konfigurator/konfigurator.js

Then apply the file you like to:

git checkout stash@{1} -- <filename>

or whole folder:

git checkout stash@{1} /errors

It also works without -- but it is recommended to use them. See this post.

It is also conventional to recognize a double hyphen as a signal to stop option interpretation and treat all following arguments literally.

This is my implementation of the T4 suggestion... This will increment the build number every time you build the project regardless of the selected configuration (i.e. Debug|Release), and it will increment the revision number every time you do a Release build. You can continue to update the major and minor version numbers through Application ➤ Assembly Information...

To explain in more detail, this will read the existing AssemblyInfo.cs file, and use regex to find the AssemblyVersion information and then increment the revision and build numbers based on input from TextTransform.exe.

1. Delete your existing AssemblyInfo.cs file.

2. Create a AssemblyInfo.tt file in its place. Visual Studio should create AssemblyInfo.cs and group it with the T4 file after you save the T4 file.

   <#@ template debug="true" hostspecific="true" language="C#" #>
   <#@ output extension=".cs" #>
   <#@ import namespace="System.IO" #>
   <#@ import namespace="System.Text.RegularExpressions" #>
   <#
       string output = File.ReadAllText(this.Host.ResolvePath("AssemblyInfo.cs"));
       Regex pattern = new Regex("AssemblyVersion\\(\"(?<major>\\d+)\\.(?<minor>\\d+)\\.(?<revision>\\d+)\\.(?<build>\\d+)\"\\)");
       MatchCollection matches = pattern.Matches(output);
       if( matches.Count == 1 )
       {
           major = Convert.ToInt32(matches[0].Groups["major"].Value);
           minor = Convert.ToInt32(matches[0].Groups["minor"].Value);
           build = Convert.ToInt32(matches[0].Groups["build"].Value) + 1;
           revision = Convert.ToInt32(matches[0].Groups["revision"].Value);
           if( this.Host.ResolveParameterValue("-","-","BuildConfiguration") == "Release" )
               revision++;
       }
   #>
   
   using System.Reflection;
   using System.Runtime.CompilerServices;
   using System.Runtime.InteropServices;
   using System.Resources;
   
   // General Information
   [assembly: AssemblyTitle("Insert title here")]
   [assembly: AssemblyDescription("Insert description here")]
   [assembly: AssemblyConfiguration("")]
   [assembly: AssemblyCompany("Insert company here")]
   [assembly: AssemblyProduct("Insert product here")]
   [assembly: AssemblyCopyright("Insert copyright here")]
   [assembly: AssemblyTrademark("Insert trademark here")]
   [assembly: AssemblyCulture("")]
   
   // Version informationr(
   [assembly: AssemblyVersion("<#= this.major #>.<#= this.minor #>.<#= this.revision #>.<#= this.build #>")]
   [assembly: AssemblyFileVersion("<#= this.major #>.<#= this.minor #>.<#= this.revision #>.<#= this.build #>")]
   [assembly: NeutralResourcesLanguageAttribute( "en-US" )]
   
   <#+
       int major = 1;
       int minor = 0;
       int revision = 0;
       int build = 0;
   #>
   

3. Add this to your pre-build event:

   "%CommonProgramFiles(x86)%\microsoft shared\TextTemplating\$(VisualStudioVersion)\TextTransform.exe" -a !!BuildConfiguration!$(Configuration) "$(ProjectDir)Properties\AssemblyInfo.tt"
   

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

no, but it runs fine on win64, and can create win64 .EXEs

Sorting NSMutableArray is very simple:

NSMutableArray *arrayToFilter =
     [[NSMutableArray arrayWithObjects:@"Photoshop",
                                       @"Flex",
                                       @"AIR",
                                       @"Flash",
                                       @"Acrobat", nil] autorelease];

NSMutableArray *productsToRemove = [[NSMutableArray array] autorelease];

for (NSString *products in arrayToFilter) {
    if (fliterText &&
        [products rangeOfString:fliterText
                        options:NSLiteralSearch|NSCaseInsensitiveSearch].length == 0)

        [productsToRemove addObject:products];
}
[arrayToFilter removeObjectsInArray:productsToRemove];

I was able to achieve the desired result by using Alt + Shift + up/down and then typing the desired comment characters and additional character.

GCC compilers always try to compile your program if this is at all possible. However, in some cases, the C and C++ standards specify that certain extensions are forbidden. Conforming compilers such as gcc or g++ must issue a diagnostic when these extensions are encountered. For example, the gcc compiler’s -pedantic option causes gcc to issue warnings in such cases. Using the stricter -pedantic-errors option converts such diagnostic warnings into errors that will cause compilation to fail at such points. Only those non-ISO constructs that are required to be flagged by a conforming compiler will generate warnings or errors.

This can be done using HTML5's placeHolder or using JavaScript. Checkout this post.

another example:

Reading file one row at the time. Removing unwanted chars with from end of the string str.rstrip(chars)

with open(filename, 'r') as fileobj:
    for row in fileobj:
        print( row.rstrip('\n') )

see also str.strip([chars]) and str.lstrip([chars])

(python >= 2.0)

dynamic dynJson = JsonConvert.DeserializeObject(json);
foreach (var item in dynJson)
{
    Console.WriteLine("{0} {1} {2} {3}\n", item.id, item.displayName, 
        item.slug, item.imageUrl);
}

or

var list = JsonConvert.DeserializeObject<List<MyItem>>(json);

public class MyItem
{
    public string id;
    public string displayName;
    public string name;
    public string slug;
    public string imageUrl;
}

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

This seems to work for me:

LANG=C grep --only-matching --byte-offset --binary --text --perl-regexp "<\x-hex pattern>" <file>

short form:

LANG=C grep -obUaP "<\x-hex pattern>" <file>

Example:

LANG=C grep -obUaP "\x01\x02" /bin/grep

Output (cygwin binary):

153: <\x01\x02>
33210: <\x01\x02>
53453: <\x01\x02>

So you can grep this again to extract offsets. But don't forget to use binary mode again.

Note: LANG=C is needed to avoid utf8 encoding issues.

You can do this:-

$('#about-link').addClass('current');
$('#menu li a').on('click', function(e){
    e.preventDefault();
    $('#menu li a.current').removeClass('current');
    $(this).addClass('current');
});

Demo: Fiddle

Being inspired by @dubiousjim's solution, I propose to use an additional general check of whether is it something iterable

import collections
def is_empty(a):
    return not a and isinstance(a, collections.Iterable)

Note: a string is considered to be iterable. - add and not isinstance(a,(str,unicode)) if you want the empty string to be excluded

Test:

>>> is_empty('sss')
False
>>> is_empty(555)
False
>>> is_empty(0)
False
>>> is_empty('')
True
>>> is_empty([3])
False
>>> is_empty([])
True
>>> is_empty({})
True
>>> is_empty(())
True

Look at this pandas three-way joining multiple dataframes on columns

filenames = ['fn1', 'fn2', 'fn3', 'fn4',....]
dfs = [pd.read_csv(filename, index_col=index_col) for filename in filenames)]
dfs[0].join(dfs[1:])

Warnings are annoying. As mentioned in other answers, you can suppress them using:

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

But if you want to handle them one by one and you are managing a bigger codebase, it will be difficult to find the line of code which is causing the warning. Since warnings unlike errors don't come with code traceback. In order to trace warnings like errors, you can write this at the top of the code:

import warnings
warnings.filterwarnings("error")

But if the codebase is bigger and it is importing bunch of other libraries/packages, then all sort of warnings will start to be raised as errors. In order to raise only certain type of warnings (in your case, its FutureWarning) as error, you can write:

import warnings
warnings.simplefilter(action='error', category=FutureWarning)

For second highest salary, This one work for me:

SELECT salary
FROM employee
WHERE salary 
NOT IN (
SELECT MAX( salary ) 
FROM employee
ORDER BY salary DESC
)
LIMIT 1

This is one of the simplest query for the same that I came across and we use it for monitoring as well:

SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024/1024 "FREE SPACE(GB)"
FROM DBA_FREE_SPACE GROUP BY TABLESPACE_NAME;

If you do what it suggests and recompile with the "-Xlint:unchecked" switch, it will give you more detailed information.

As well as the use of raw types (as described by the other answers), an unchecked cast can also cause the warning.

Once you've compiled with -Xlint, you should be able to rework your code to avoid the warning. This is not always possible, particularly if you are integrating with legacy code that cannot be changed. In this situation, you may decide to suppress the warning in places where you know that the code is correct:

@SuppressWarnings("unchecked")
public void myMethod()
{
    //...
}

I ran into this scenario recently (well over 7 million rows) and eneded up using sqlcmd via powershell (after parsing raw data into SQL insert statements) in segments of 5,000 at a time (SQL can't handle 7 million lines in one lump job or even 500,000 lines for that matter unless its broken down into smaller 5K pieces. You can then run each 5K script one after the other.) as I needed to leverage the new sequence command in SQL Server 2012 Enterprise. I couldn't find a programatic way to insert seven million rows of data quickly and efficiently with said sequence command.

Secondly, one of the things to look out for when inserting a million rows or more of data in one sitting is the CPU and memory consumption (mostly memory) during the insert process. SQL will eat up memory/CPU with a job of this magnitude without releasing said processes. Needless to say if you don't have enough processing power or memory on your server you can crash it pretty easily in a short time (which I found out the hard way). If you get to the point to where your memory consumption is over 70-75% just reboot the server and the processes will be released back to normal.

I had to run a bunch of trial and error tests to see what the limits for my server was (given the limited CPU/Memory resources to work with) before I could actually have a final execution plan. I would suggest you do the same in a test environment before rolling this out into production.

While maintaining the proper .gitignore file is helpful, I found this alternate approach is way cleaner and easier to use.

• Create dummy folder my_project and inside that git clone my_real_project the actual project repo.
• Now while opening the project in IDE (Intellij/Pycharm) open the folder my_project and mark my_project/my_real_project as the VCS root.
• You can see my_project/.idea wouldn't pollute your git repo because it happily lives outside the git repo which is what you want. This way your .gitignore files stays clean as well.

This approach works better due to the below reasons.

1 - .gitignore file stays clean and we don't have to insert lines related to JetBrains products, that file is better used for binaries and libraries and autogen contents.

2 - Intellij keeps updating their projects and the files inside .idea keep changing every significant release from JB. What this means is we have to keep updating our .gitignore accordingly which is not an ideal use of time.

3 - Intellij has the flawed pattern here, most editors Atom, VS Code, Eclipse... nobody stores their IDE contents right inside project root. JB shouldn't be an exception either. It's the onus of Jetbrains to keep those files tracked outside project root. They have to refrain from polluting VCS root. This approach does just that. The .idea folder is kept outside the PROJECT_ROOT

Hope this helps.

This is a question about scope.

If you only want the variables to last the lifetime of the function, use Dim (short for Dimension) inside the function or sub to declare the variables:

Function AddSomeNumbers() As Integer
    Dim intA As Integer
    Dim intB As Integer
    intA = 2
    intB = 3
    AddSomeNumbers = intA + intB
End Function
'intA and intB are no longer available since the function ended

A global variable (as SLaks pointed out) is declared outside of the function using the Public keyword. This variable will be available during the life of your running application. In the case of Excel, this means the variables will be available as long as that particular Excel workbook is open.

Public intA As Integer
Private intB As Integer

Function AddSomeNumbers() As Integer
    intA = 2
    intB = 3
    AddSomeNumbers = intA + intB
End Function
'intA and intB are still both available.  However, because intA is public,  '
'it can also be referenced from code in other modules. Because intB is private,'
'it will be hidden from other modules.

You can also have variables that are only accessible within a particular module (or class) by declaring them with the Private keyword.

If you're building a big application and feel a need to use global variables, I would recommend creating a separate module just for your global variables. This should help you keep track of them in one place.

Whilst agreeing with Douwe Maan and Erik's answers, there are a couple of other things here that you may find useful.

Firstly, within your head tags, you can reference a separate JavaScript file, which is then reusable:

<script language="JavaScript" src="/common/common.js"></script>

where common.js is your reusable function file in a top-level directory called common.

Secondly, you can delay the operation of a script using setTimeout, e.g.:

setTimeout(someFunction, 5000);

The second argument is in milliseconds. I mention this, because you appear to be trying to delay something in your original code snippet.

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com

It's an old question, but still active as there is no explicit Android feature. And the guys from facebook found a work around - somehow. Today, I found a way that works for me. Not perfect (see remarks at the end of this answer) but it works!

Main idea is, that I update the icon of my app's shortcut, created by the launcher on my home screen. When I want to change something on the shortcut-icon, I remove it first and recreate it with a new bitmap.

Here is the code. It has a button increment. When pressed, the shortcut is replaced with one that has a new counting number.

First you need these two permissions in your manifest:

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

Then you need this two methods for installing and uninstalling shortcuts. The shortcutAdd method creates a bitmap with a number in it. This is just to demonstrate that it actually changes. You probably want to change that part with something, you want in your app.

private void shortcutAdd(String name, int number) {
    // Intent to be send, when shortcut is pressed by user ("launched")
    Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
    shortcutIntent.setAction(Constants.ACTION_PLAY);

    // Create bitmap with number in it -> very default. You probably want to give it a more stylish look
    Bitmap bitmap = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888);
    Paint paint = new Paint();
    paint.setColor(0xFF808080); // gray
    paint.setTextAlign(Paint.Align.CENTER);
    paint.setTextSize(50);
    new Canvas(bitmap).drawText(""+number, 50, 50, paint);
    ((ImageView) findViewById(R.id.icon)).setImageBitmap(bitmap);

    // Decorate the shortcut
    Intent addIntent = new Intent();
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bitmap);

    // Inform launcher to create shortcut
    addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    getApplicationContext().sendBroadcast(addIntent);
}

private void shortcutDel(String name) {
    // Intent to be send, when shortcut is pressed by user ("launched")
    Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
    shortcutIntent.setAction(Constants.ACTION_PLAY);

    // Decorate the shortcut
    Intent delIntent = new Intent();
    delIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    delIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);

    // Inform launcher to remove shortcut
    delIntent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
    getApplicationContext().sendBroadcast(delIntent);
}

And finally, here are two listener to add the first shortcut and update the shortcut with an incrementing counter.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.test);
    findViewById(R.id.add).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            shortcutAdd("changeIt!", count);
        }
    });
    findViewById(R.id.increment).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            shortcutDel("changeIt!");
            count++;
            shortcutAdd("changeIt!", count);
        }
    });
}

Remarks:

• This way works also if your App controls more shortcuts on the home screen, e.g. with different extra's in the Intent. They just need different names so that the right one is uninstalled and reinstalled.

• The programmatical handling of shortcuts in Android is a well known, widely used but not officially supported Android feature. It seems to work on the default launcher and I never tried it anywhere else. So dont blame me, when you get this user-emails "It does not work on my XYZ, double rooted, super blasted phone"

• The launcher writes a Toast when a shortcut was installad and one when a shortcut was uninstalled. So I get two Toasts every time I change the icon. This is not perfect, but well, as long as the rest of my app is perfect...

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

1. Choose project, right click, in context menu, choose Show in Explorer (on Mac, select Reveal in Finder).

2. Choose menu File \ Close Project

3. In Windows Explorer, press Del or Shift+Del for permanent delete.

4. At IntelliJ IDEA startup windows, hover cursor on old project name (what has been deleted) press Del for delelte.

Either use casting as others have already said, or multiply one of the int variables by 1.0:

double firstSolution = ((1.0* b1 * a22 - b2 * a12) / (a11 * a22 - a12 * a21));

Here on a openSuse 12.3 the solution was installing the 32-bit version of libaio in addition. Oracle seems to need this now, although on 12.1 it run without the 32-bit version.

You can use 0 or ^ to move to beginning of the line.
And can use Shift+I to move to the beginning and switch to editing mode (Insert).

You are not changing the value of line. It should be something like this.

import java.io.BufferedReader;
import java.io.FileReader;

public class InsertValuesIntoTestDb {

  @SuppressWarnings("rawtypes")
  public static void main(String[] args) throws Exception {
      String splitBy = ",";
      BufferedReader br = new BufferedReader(new FileReader("test.csv"));
      while((line = br.readLine()) != null){
           String[] b = line.split(splitBy);
           System.out.println(b[0]);
      }
      br.close();

  }
}

readLine returns each line and only returns null when there is nothing left. The above code sets line and then checks if it is null.

export in sh and related shells (such as bash), marks an environment variable to be exported to child-processes, so that the child inherits them.

export is defined in POSIX:

The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.

jquery will execute both handler since it allows multiple event handlers. I have created sample code. You can try it

I created a DefaultableDictionary to do exactly what you are asking for!

using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;

namespace DefaultableDictionary {
    public class DefaultableDictionary<TKey, TValue> : IDictionary<TKey, TValue> {
        private readonly IDictionary<TKey, TValue> dictionary;
        private readonly TValue defaultValue;

        public DefaultableDictionary(IDictionary<TKey, TValue> dictionary, TValue defaultValue) {
            this.dictionary = dictionary;
            this.defaultValue = defaultValue;
        }

        public IEnumerator<KeyValuePair<TKey, TValue>> GetEnumerator() {
            return dictionary.GetEnumerator();
        }

        IEnumerator IEnumerable.GetEnumerator() {
            return GetEnumerator();
        }

        public void Add(KeyValuePair<TKey, TValue> item) {
            dictionary.Add(item);
        }

        public void Clear() {
            dictionary.Clear();
        }

        public bool Contains(KeyValuePair<TKey, TValue> item) {
            return dictionary.Contains(item);
        }

        public void CopyTo(KeyValuePair<TKey, TValue>[] array, int arrayIndex) {
            dictionary.CopyTo(array, arrayIndex);
        }

        public bool Remove(KeyValuePair<TKey, TValue> item) {
            return dictionary.Remove(item);
        }

        public int Count {
            get { return dictionary.Count; }
        }

        public bool IsReadOnly {
            get { return dictionary.IsReadOnly; }
        }

        public bool ContainsKey(TKey key) {
            return dictionary.ContainsKey(key);
        }

        public void Add(TKey key, TValue value) {
            dictionary.Add(key, value);
        }

        public bool Remove(TKey key) {
            return dictionary.Remove(key);
        }

        public bool TryGetValue(TKey key, out TValue value) {
            if (!dictionary.TryGetValue(key, out value)) {
                value = defaultValue;
            }

            return true;
        }

        public TValue this[TKey key] {
            get
            {
                try
                {
                    return dictionary[key];
                } catch (KeyNotFoundException) {
                    return defaultValue;
                }
            }

            set { dictionary[key] = value; }
        }

        public ICollection<TKey> Keys {
            get { return dictionary.Keys; }
        }

        public ICollection<TValue> Values {
            get
            {
                var values = new List<TValue>(dictionary.Values) {
                    defaultValue
                };
                return values;
            }
        }
    }

    public static class DefaultableDictionaryExtensions {
        public static IDictionary<TKey, TValue> WithDefaultValue<TValue, TKey>(this IDictionary<TKey, TValue> dictionary, TValue defaultValue ) {
            return new DefaultableDictionary<TKey, TValue>(dictionary, defaultValue);
        }
    }
}

This project is a simple decorator for an IDictionary object and an extension method to make it easy to use.

The DefaultableDictionary will allow for creating a wrapper around a dictionary that provides a default value when trying to access a key that does not exist or enumerating through all the values in an IDictionary.

Example: var dictionary = new Dictionary<string, int>().WithDefaultValue(5);

Blog post on the usage as well.

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html You should be able to see if there are any issues with your ssl certificate chain. I am guessing that you have SSL chain issues. A short description of the problem is that there's actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

Try using the COLUMN command with the FORMAT option for that:

COLUMN COLUMN_NAME FORMAT 99.99
SELECT COLUMN_NAME FROM ....

For those who have updated to the latest version of google-play-services_lib and/or have this error Google Play services out of date. Requires 3136100 but found 2012110 this newer version of com.google.android.gms.apk (Google Play Services 3.1.36) and com.android.vending.apk (Google Play Store 4.1.6) should work.

Test with this configuration on Android SDK Tools 22.0.1. Another configuration that targets pure Android, not the Google one, should work too.

• Device: Galaxy Nexus
• Target: Android 4.2.2 - API Level 17
• CPU/ABI: ARM (armeabi-v7a)
• Checked: Use Host GPU

...

1. Open the AVD

2. Execute this in the terminal / cmd

   adb -e install com.google.android.gms.apk
   adb -e install com.android.vending.apk
   

3. Restart the AVD

4. Have fun coding!!!

I found this way to be the easiest, cleanest and it works with the newest version of the software, which allow you to get all the bug fixes.
