Do you mean Delegate.Invoke/BeginInvoke or Control.Invoke/BeginInvoke?

• Delegate.Invoke: Executes synchronously, on the same thread.
• Delegate.BeginInvoke: Executes asynchronously, on a threadpool thread.
• Control.Invoke: Executes on the UI thread, but calling thread waits for completion before continuing.
• Control.BeginInvoke: Executes on the UI thread, and calling thread doesn't wait for completion.

Tim's answer mentions when you might want to use BeginInvoke - although it was mostly geared towards Delegate.BeginInvoke, I suspect.

For Windows Forms apps, I would suggest that you should usually use BeginInvoke. That way you don't need to worry about deadlock, for example - but you need to understand that the UI may not have been updated by the time you next look at it! In particular, you shouldn't modify data which the UI thread might be about to use for display purposes. For example, if you have a Person with FirstName and LastName properties, and you did:

person.FirstName = "Kevin"; // person is a shared reference
person.LastName = "Spacey";
control.BeginInvoke(UpdateName);
person.FirstName = "Keyser";
person.LastName = "Soze";

Then the UI may well end up displaying "Keyser Spacey". (There's an outside chance it could display "Kevin Soze" but only through the weirdness of the memory model.)

Unless you have this sort of issue, however, Control.BeginInvoke is easier to get right, and will avoid your background thread from having to wait for no good reason. Note that the Windows Forms team has guaranteed that you can use Control.BeginInvoke in a "fire and forget" manner - i.e. without ever calling EndInvoke. This is not true of async calls in general: normally every BeginXXX should have a corresponding EndXXX call, usually in the callback.

It seems to me that you are operating on at least one false assumption.

1. You don't need to raise the ProgressChanged event to have a responsive UI

In your question you say this:

BackgroundWorker is not the answer because it may be that I don't get the progress notification, which means there would be no call to ProgressChanged as the DoWork is a single call to an external function . . .

Actually, it does not matter whether you call the ProgressChanged event or not. The whole purpose of that event is to temporarily transfer control back to the GUI thread to make an update that somehow reflects the progress of the work being done by the BackgroundWorker. If you are simply displaying a marquee progress bar, it would actually be pointless to raise the ProgressChanged event at all. The progress bar will continue rotating as long as it is displayed because the BackgroundWorker is doing its work on a separate thread from the GUI.

(On a side note, DoWork is an event, which means that it is not just "a single call to an external function"; you can add as many handlers as you like; and each of those handlers can contain as many function calls as it likes.)

2. You don't need to call Application.DoEvents to have a responsive UI

To me it sounds like you believe that the only way for the GUI to update is by calling Application.DoEvents:

I need to keep call the Application.DoEvents(); for the progress bar to keep rotating.

This is not true in a multithreaded scenario; if you use a BackgroundWorker, the GUI will continue to be responsive (on its own thread) while the BackgroundWorker does whatever has been attached to its DoWork event. Below is a simple example of how this might work for you.

private void ShowProgressFormWhileBackgroundWorkerRuns() {
    // this is your presumably long-running method
    Action<string, string> exec = DoSomethingLongAndNotReturnAnyNotification;

    ProgressForm p = new ProgressForm(this);

    BackgroundWorker b = new BackgroundWorker();

    // set the worker to call your long-running method
    b.DoWork += (object sender, DoWorkEventArgs e) => {
        exec.Invoke(path, parameters);
    };

    // set the worker to close your progress form when it's completed
    b.RunWorkerCompleted += (object sender, RunWorkerCompletedEventArgs e) => {
        if (p != null && p.Visible) p.Close();
    };

    // now actually show the form
    p.Show();

    // this only tells your BackgroundWorker to START working;
    // the current (i.e., GUI) thread will immediately continue,
    // which means your progress bar will update, the window
    // will continue firing button click events and all that
    // good stuff
    b.RunWorkerAsync();
}

3. You can't run two methods at the same time on the same thread

You say this:

I just need to call Application.DoEvents() so that the Marque progress bar will work, while the worker function works in the Main thread . . .

What you're asking for is simply not real. The "main" thread for a Windows Forms application is the GUI thread, which, if it's busy with your long-running method, is not providing visual updates. If you believe otherwise, I suspect you misunderstand what BeginInvoke does: it launches a delegate on a separate thread. In fact, the example code you have included in your question to call Application.DoEvents between exec.BeginInvoke and exec.EndInvoke is redundant; you are actually calling Application.DoEvents repeatedly from the GUI thread, which would be updating anyway. (If you found otherwise, I suspect it's because you called exec.EndInvoke right away, which blocked the current thread until the method finished.)

So yes, the answer you're looking for is to use a BackgroundWorker.

You could use BeginInvoke, but instead of calling EndInvoke from the GUI thread (which will block it if the method isn't finished), pass an AsyncCallback parameter to your BeginInvoke call (instead of just passing null), and close the progress form in your callback. Be aware, however, that if you do that, you're going to have to invoke the method that closes the progress form from the GUI thread, since otherwise you'll be trying to close a form, which is a GUI function, from a non-GUI thread. But really, all the pitfalls of using BeginInvoke/EndInvoke have already been dealt with for you with the BackgroundWorker class, even if you think it's ".NET magic code" (to me, it's just an intuitive and useful tool).

Action is a Type of Delegate provided by the .NET framework. The Action points to a method with no parameters and does not return a value.

() => is lambda expression syntax. Lambda expressions are not of Type Delegate. Invoke requires Delegate so Action can be used to wrap the lambda expression and provide the expected Type to Invoke()

Invoke causes said Action to execute on the thread that created the Control's window handle. Changing threads is often necessary to avoid Exceptions. For example, if one tries to set the Rtf property on a RichTextBox when an Invoke is necessary, without first calling Invoke, then a Cross-thread operation not valid exception will be thrown. Check Control.InvokeRequired before calling Invoke.

BeginInvoke is the Asynchronous version of Invoke. Asynchronous means the thread will not block the caller as opposed to a synchronous call which is blocking.

If you're using Symfony 2 security management, you don't need to get posted values, you only need to manage form template (see documentation).

If you aren't using Symfony 2 security management, I advise you strongly to use it. If you don't want to or if you can't, can you give us the LoginType's sources ?

git pull origin develop

Since pulling a branch into another directly merges them together

This did the magic for me. chmod -Rf 0777 storage

It is just a typo(I guess)-

p+=1;

instead of p +1=p; is required .

As name suggest lvalue expression should be left-hand operand of the assignment operator.

Try to use toISOString(). It returns string in ISO8601 format.

GET method

javascript

$.get('/example/doGet?date=' + new Date().toISOString(), function (result) {
    console.log(result);
});

c#

[HttpGet]
public JsonResult DoGet(DateTime date)
{
    return Json(date.ToString(), JsonRequestBehavior.AllowGet);
}

POST method

javascript

$.post('/example/do', { date: date.toISOString() }, function (result) {
    console.log(result);
});

c#

[HttpPost]
public JsonResult Do(DateTime date)
{
     return Json(date.ToString());
}

Why not try find /usr/include/X11 -name Xlib.h

If there is a hit, you have Xlib.h

If not install it using sudo apt-get install libx11-dev

and you are good to go :)

With Java 8, you can do this:

int[] haystack = {1, 2, 3};
int needle = 3;

boolean found = Arrays.stream(haystack).anyMatch(x -> x == needle);

You'd need to do

boolean found = Arrays.stream(haystack).anyMatch(x -> needle.equals(x));

if you're working with objects.

A (partial) practical work-around is to put things into a throw-away function.

Pasting

x = 1
x += 1
print(x)

results in

>>> x = 1
x += 1
print(x)
  File "<stdin>", line 1
    x += 1
print(x)

    ^
SyntaxError: multiple statements found while compiling a single statement
>>>

However, pasting

def abc():
  x = 1
  x += 1
  print(x)

works:

>>> def abc():
  x = 1
  x += 1
  print(x)
>>> abc()
2
>>>

Of course, this is OK for a quick one-off, won't work for everything you might want to do, etc. But then, going to ipython / jupyter qtconsole is probably the next simplest option.

A trap is a special kind of interrupt which is commonly referred to as a software interrupt. An interrupt is a more general term which covers both hardware interrupts (interrupts from hardware devices) and software interrupts (interrupts from software, such as traps).

I bet you didn't know you were functional programming when you used:

• Excel formulas
• Quartz Composer
• JavaScript
• Logo (Turtle graphics)
• LINQ
• SQL
• Underscore.js (or Lodash), D3

You are looking for the cp command. You need to change directories so that you are outside of the directory you are trying to copy.

If the directory you're copying is called dir1 and you want to copy it to your /home/Pictures folder:

cp -r dir1/ ~/Pictures/

Linux is case-sensitive and also needs the / after each directory to know that it isn't a file. ~ is a special character in the terminal that automatically evaluates to the current user's home directory. If you need to know what directory you are in, use the command pwd.

When you don't know how to use a Linux command, there is a manual page that you can refer to by typing:

man [insert command here]

at a terminal prompt.

Also, to auto complete long file paths when typing in the terminal, you can hit Tab after you've started typing the path and you will either be presented with choices, or it will insert the remaining part of the path.

I found a good example showing the differences between all hibernate save methods:

http://www.journaldev.com/3481/hibernate-session-merge-vs-update-save-saveorupdate-persist-example

In brief, according to the above link:

save()

• We can invoke this method outside a transaction. If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session.
• So, if there are other objects mapped from the primary object, they gets saved at the time of committing transaction or when we flush the session.

persist()

• Its similar to using save() in transaction, so it’s safe and takes care of any cascaded objects.

saveOrUpdate()

• Can be used with or without the transaction, and just like save(), if its used without the transaction, mapped entities wont be saved un;ess we flush the session.

• Results into insert or update queries based on the provided data. If the data is present in the database, update query is executed.

update()

• Hibernate update should be used where we know that we are only updating the entity information. This operation adds the entity object to persistent context and further changes are tracked and saved when transaction is committed.
• Hence even after calling update, if we set any values in the entity,they will be updated when transaction commits.

merge()

• Hibernate merge can be used to update existing values, however this method create a copy from the passed entity object and return it. The returned object is part of persistent context and tracked for any changes, passed object is not tracked. This is the major difference with merge() from all other methods.

Also for practical examples of all these, please refer to the link I mentioned above, it shows examples for all these different methods.

Check whether your app has the needed permissions.I was also getting the same error and I checked the logcat debug log which showed this:

04-15 13:38:25.387: E/AndroidRuntime(694): java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:555-555-5555 cmp=com.android.phone/.OutgoingCallBroadcaster } from ProcessRecord{44068640 694:rahulserver.test/10055} (pid=694, uid=10055) requires android.permission.CALL_PHONE

I then gave the needed permission in my android-manifest which worked for me.

Add a margin to your li tags. That will create space between the li and you can use line-height to set the spacing to the text within the li tags.

You could also get this error if you are viewing accessing the page locally (via file:// instead of http://)..

There is some discussion about this here: https://github.com/jeromegn/Backbone.localStorage/issues/55

Internally devtools injects an IIFE named getCompletions into the page, called when a key is pressed inside the Devtools console.

Looking at the source of that function, it uses a few global functions which can be overwritten.

By using the Error constructor it's possible to get the call stack, which will include getCompletions when called by Devtools.

Example:

const disableDevtools = callback => {_x000D_
  const original = Object.getPrototypeOf;_x000D_
_x000D_
  Object.getPrototypeOf = (...args) => {_x000D_
    if (Error().stack.includes("getCompletions")) callback();_x000D_
    return original(...args);_x000D_
  };_x000D_
};_x000D_
_x000D_
disableDevtools(() => {_x000D_
  console.error("devtools has been disabled");_x000D_
_x000D_
  while (1);_x000D_
});

The short answer is: No. The only way to post images is through the mobile app.

From the Instagram API documentation: http://instagram.com/developer/endpoints/media/

At this time, uploading via the API is not possible. We made a conscious choice not to add this for the following reasons:

• Instagram is about your life on the go – we hope to encourage photos from within the app. However, in the future we may give whitelist access to individual apps on a case by case basis.
• We want to fight spam & low quality photos. Once we allow uploading from other sources, it's harder to control what comes into the Instagram ecosystem.

All this being said, we're working on ways to ensure users have a consistent and high-quality experience on our platform.

I am loading html pages from Documents and if they have the same name of css file UIWebView it seem it does not throw the previous css rules. Maybe because they have the same URL or something.

I tried this:

NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil];
[NSURLCache setSharedURLCache:sharedCache];
[sharedCache release];

I tried this :

[[NSURLCache sharedURLCache] removeAllCachedResponses];

I am loading the initial page with:

NSURLRequest *appReq = [NSURLRequest requestWithURL:appURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0];

It refuses to throw its cached data! Frustrating!

I am doing this inside a PhoneGap (Cordova) application. I have not tried it in isolated UIWebView.

Update1: I have found this.
Changing the html files, though seems very messy.

It's fine just to cast your int to Foo:

int i = 1;
Foo f = (Foo)i;

If you try to cast a value that's not defined it will still work. The only harm that may come from this is in how you use the value later on.

If you really want to make sure your value is defined in the enum, you can use Enum.IsDefined:

int i = 1;
if (Enum.IsDefined(typeof(Foo), i))
{
    Foo f = (Foo)i;
}
else
{
   // Throw exception, etc.
}

However, using IsDefined costs more than just casting. Which you use depends on your implemenation. You might consider restricting user input, or handling a default case when you use the enum.

Also note that you don't have to specify that your enum inherits from int; this is the default behavior.

If you just want to get the current UNIX timestamp I'd just use time()

$timestamp = time(); 

Kotlin create class SafeClickListener

class SafeClickListener(
        private var defaultInterval: Int = 1000,
        private val onSafeCLick: (View) -> Unit
) : View.OnClickListener {
    private var lastTimeClicked: Long = 0    override fun onClick(v: View) {
        if (SystemClock.elapsedRealtime() - lastTimeClicked < defaultInterval) {
            return
        }
        lastTimeClicked = SystemClock.elapsedRealtime()
        onSafeCLick(v)
    }
}

create a function in baseClass or else

fun View.setSafeOnClickListener(onSafeClick: (View) -> Unit) {val safeClickListener = SafeClickListener {
        onSafeClick(it)
    }
    setOnClickListener(safeClickListener)
}

and use on button click

btnSubmit.setSafeOnClickListener {
    showSettingsScreen()
}

If you don't mention the random_state in the code, then whenever you execute your code a new random value is generated and the train and test datasets would have different values each time.

However, if you use a particular value for random_state(random_state = 1 or any other value) everytime the result will be same,i.e, same values in train and test datasets. Refer below code:

import pandas as pd 
from sklearn.model_selection import train_test_split
test_series = pd.Series(range(100))
size30split = train_test_split(test_series,random_state = 1,test_size = .3)
size25split = train_test_split(test_series,random_state = 1,test_size = .25)
common = [element for element in size25split[0] if element in size30split[0]]
print(len(common))

Doesn't matter how many times you run the code, the output will be 70.

70

Try to remove the random_state and run the code.

import pandas as pd 
from sklearn.model_selection import train_test_split
test_series = pd.Series(range(100))
size30split = train_test_split(test_series,test_size = .3)
size25split = train_test_split(test_series,test_size = .25)
common = [element for element in size25split[0] if element in size30split[0]]
print(len(common))

Now here output will be different each time you execute the code.

JPA was designed to provide an automatic mapping between Objects and a relational database. Since Integer is not a persistant entity, why do you need to use JPA ? A simple JDBC request will work fine.

One cool solution might be separating all environment-specific values into some separate angular module, that all other modules depend on:

angular.module('configuration', [])
       .constant('API_END_POINT','123456')
       .constant('HOST','localhost');

Then your modules that need those entries can declare a dependency on it:

angular.module('services',['configuration'])
       .factory('User',['$resource','API_END_POINT'],function($resource,API_END_POINT){
           return $resource(API_END_POINT + 'user');
       });

Now you could think about further cool stuff:

The module, that contains the configuration can be separated into configuration.js, that will be included at your page.

This script can be easily edited by each of you, as long as you don’t check this separate file into git. But it's easier to not check in the configuration if it is in a separate file. Also, you could branch it locally.

Now, if you have a build-system, like ANT or Maven, your further steps could be implementing some placeholders for the values API_END_POINT, that will be replaced during build-time, with your specific values.

Or you have your configuration_a.js and configuration_b.js and decide at the backend which to include.

This just happen to me because in the php.ini the date.timezone was not set!

;date.timezone=Europe/Berlin

Using the php date() function triggered that warning.

I had this problem after changing the git access password!

I had to reset the credentials through the PowerShell console.

At the git repository folder level, the script was as follows:

git config --system --unset credential.helper

git config --system credential.helper store

git fetch

You will be prompted for the user and then the password.

The next command will no longer request authentication:

git fetch

The question does not contain a nested loop, just a single loop. But THIS nested version works, too:

c a
c b

Another easy way to circumvent google's check is to use another compression algorithm with tar, like bz2:

tar -cvjf my.tar.bz2 dir/

Note that 'j' (for bz2 compression) is used above instead of 'z' (gzip compression).

This function will work properly :)

I would like to share what I understood from this keyword. This keyword has 6 usages in java as follows:-

1. It can be used to refer to the current class variable. Let us understand with a code.*

Let's understand the problem if we don't use this keyword by the example given below:

class Employee{  
int id_no;  
String name;  
float salary;  
Student(int id_no,String name,float salary){  
id_no = id_no;  
name=name;  
salary = salary;  
}  
void display(){System.out.println(id_no +" "+name+" "+ salary);}  
}  
class TestThis1{  
public static void main(String args[]){  
Employee s1=new Employee(111,"ankit",5000f);  
Employee s2=new Employee(112,"sumit",6000f);  
s1.display();  
s2.display();  
}}  

Output:-

0 null 0.0
0 null 0.0

In the above example, parameters (formal arguments) and instance variables are same. So, we are using this keyword to distinguish local variable and instance variable.

class Employee{  
int id_no;  
String name;  
float salary;  
Student(int id_no,String name,float salary){  
this.id_no = id_no;  
this.name=name;  
this.salary = salary;  
}  
void display(){System.out.println(id_no +" "+name+" "+ salary);}  
}  
class TestThis1{  
public static void main(String args[]){  
Employee s1=new Employee(111,"ankit",5000f);  
Employee s2=new Employee(112,"sumit",6000f);  
s1.display();  
s2.display();  
}} 

output:

111 ankit 5000
112 sumit 6000

2. To invoke the current class method.

class A{  
void m(){System.out.println("hello Mandy");}  
void n(){  
System.out.println("hello Natasha");  
//m();//same as this.m()  
this.m();  
}  
}  
class TestThis4{  
public static void main(String args[]){  
A a=new A();  
a.n();  
}}  

Output:

hello Natasha
hello Mandy

3. to invoke the current class constructor. It is used to constructor chaining.

class A{  
A(){System.out.println("hello ABCD");}  
A(int x){  
this();  
System.out.println(x);  
}  
}  
class TestThis5{  
public static void main(String args[]){  
A a=new A(10);  
}}

Output:

hello ABCD
10

4. to pass as an argument in the method.

class S2{  
  void m(S2 obj){  
  System.out.println("The method is invoked");  
  }  
  void p(){  
  m(this);  
  }  
  public static void main(String args[]){  
  S2 s1 = new S2();  
  s1.p();  
  }  
}  

Output:

The method is invoked

5. to pass as an argument in the constructor call

class B{  
  A4 obj;  
  B(A4 obj){  
    this.obj=obj;  
  }  
  void display(){  
    System.out.println(obj.data);//using data member of A4 class  
  }  
}  

class A4{  
  int data=10;  
  A4(){  
   B b=new B(this);  
   b.display();  
  }  
  public static void main(String args[]){  
   A4 a=new A4();  
  }  
} 

Output:-

10

6. to return current class instance

class A{  
A getA(){  
return this;  
}  
void msg(){System.out.println("Hello");}  
}  
class Test1{  
public static void main(String args[]){  
new A().getA().msg();  
}  
}  

Output:-

Hello

Also, this keyword cannot be used without .(dot) as it's syntax is invalid.

me.Combobox1.Clear

This is the common method

The replaceAll method is attempting to match the String literal [] which does not exist within the String try replacing these items separately.

String str = "[Chrissman-@1]";
str = str.replaceAll("\\[", "").replaceAll("\\]","");

you can use below directive that get a bool value in html input for focus on it...

//js file
angular.module("appName").directive("ngFocus", function () {
       return function (scope, elem, attrs, ctrl) {
             if (attrs.ngFocus === "true") {
                 $(elem).focus();
             }
             if (!ctrl) {
                 return;
             }
       elem.on("focus", function () {
            elem.addClass("has-focus");
            scope.$apply(function () {
                ctrl.hasFocus = true;
            });
        });
    };
});

<!-- html file -->
<input type="text" ng-focus="boolValue" />

You can even set a function in your controller to ngFocus directive value pay attention to below code...

<!-- html file -->
<input type="text" ng-focus="myFunc()" />


//controller file
$scope.myFunc=function(){

this directive to happen when html page render.

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

The leading ', ' and trailing ',' are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).

That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.

In addition: don't use 'single quotes' as identifier delimiters; this syntax is deprecated. Use [square brackets] (preferred) or "double quotes" if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx

EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE syntax variant or by using something like IN()):

CASE 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

If you have more values, it might be worthwhile to use a split function, e.g.

USE tempdb;
GO

CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
   RETURN ( SELECT DISTINCT Item FROM
       ( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
         FROM ( SELECT [XML] = CONVERT(XML, '<i>'
         + REPLACE(@List,',', '</i><i>') + '</i>').query('.')
           ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
       WHERE Item IS NOT NULL
   );
GO

CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO

INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');

SELECT t.ID
  FROM dbo.[Table] AS t
  INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
  ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
  GROUP BY t.ID;
GO

Results:

ID

1

If the database is InnoDB then it might be a better idea to use foreign keys and cascade on delete, this would do what you want and also result in no redundant data being stored.

For this example however I don't think you need the first s:

DELETE s 
FROM spawnlist AS s 
INNER JOIN npc AS n ON s.npc_templateid = n.idTemplate 
WHERE n.type = "monster";

It might be a better idea to select the rows before deleting so you are sure your deleting what you wish to:

SELECT * FROM spawnlist
INNER JOIN npc ON spawnlist.npc_templateid = npc.idTemplate
WHERE npc.type = "monster";

You can also check the MySQL delete syntax here: http://dev.mysql.com/doc/refman/5.0/en/delete.html

Here is a little Python code for a dictionary class that can return random keys in O(1) time. (I included MyPy types in this code for readability):

from typing import TypeVar, Generic, Dict, List
import random

K = TypeVar('K')
V = TypeVar('V')
class IndexableDict(Generic[K, V]):
    def __init__(self) -> None:
        self.keys: List[K] = []
        self.vals: List[V] = []
        self.dict: Dict[K, int] = {}

    def __getitem__(self, key: K) -> V:
        return self.vals[self.dict[key]]

    def __setitem__(self, key: K, val: V) -> None:
        if key in self.dict:
            index = self.dict[key]
            self.vals[index] = val
        else:
            self.dict[key] = len(self.keys)
            self.keys.append(key)
            self.vals.append(val)

    def __contains__(self, key: K) -> bool:
        return key in self.dict

    def __len__(self) -> int:
        return len(self.keys)

    def random_key(self) -> K:
        return self.keys[random.randrange(len(self.keys))]

jQuery will do the job. You can use either jQuery.ajax function, which is general one for performing ajax calls, or its wrappers: jQuery.get, jQuery.post for getting/posting data. Its very easy to use, for example, check out this tutorial, which shows how to use jQuery with PHP.

If by "list" you mean a List<T>, then the Clear method is what you want:

List<string> list = ...;
...
list.Clear();

You should get into the habit of searching the MSDN documentation on these things.

Here's how to quickly search for documentation on various bits of that type:

• List Class - provides the List<T> class itself (this is where you should've started)
• List.Clear Method - provides documentation on the method Clear
• List.Count Property - provides documentation on the property Count

All of these Google queries lists a bundle of links, but typically you want the first one that google gives you in each case.

if we consider __div__ is not orthographically /

def divBy3(n):
    return n.__div__(3)

print divBy3(9), 'or', 9//3

Perl might be overkill, but it works just as well.

Removes all lines which are completely blank:

perl -ne 'print if /./' file

Removes all lines which are completely blank, or only contain whitespace:

perl -ne 'print if ! /^\s*$/' file

Variation which edits the original and makes a .bak file:

perl -i.bak -ne 'print if ! /^\s*$/' file

I use EasyGit (a.k.a. "eg") as a super lightweight wrapper on top of (or along side of) Git. EasyGit has an "info" subcommand that gives you all kinds of super useful information, including the current branches remote tracking branch. Here's an example (where the current branch name is "foo"):

pknotz@s883422: (foo) ~/workspace/bd
$ eg info
Total commits:      175

Named remote repositories: (name -> location)
  origin -> git://sahp7577/home/pknotz/bd.git

In HTML there's an autofocus attribute to all form fields. There's a good tutorial on it in Dive Into HTML 5. Unfortunately it's currently not supported by IE versions less than 10.

To use the HTML 5 attribute and fall back to a JS option:

<input id="my-input" autofocus="autofocus" />
<script>
  if (!("autofocus" in document.createElement("input"))) {
    document.getElementById("my-input").focus();
  }
</script>

No jQuery, onload or event handlers are required, because the JS is below the HTML element.

Edit: another advantage is that it works with JavaScript off in some browsers and you can remove the JavaScript when you don't want to support older browsers.

Edit 2: Firefox 4 now supports the autofocus attribute, just leaving IE without support.

Another way to do it without putting the property file on the classpath, is to set the property from the java code directly. Here is the sample code.

public class Log4JSample {

public static void main(String[] args) {
    Properties properties=new Properties();
    properties.setProperty("log4j.rootLogger","TRACE,stdout,MyFile");
    properties.setProperty("log4j.rootCategory","TRACE");

    properties.setProperty("log4j.appender.stdout",     "org.apache.log4j.ConsoleAppender");
    properties.setProperty("log4j.appender.stdout.layout",  "org.apache.log4j.PatternLayout");
    properties.setProperty("log4j.appender.stdout.layout.ConversionPattern","%d{yyyy/MM/dd HH:mm:ss.SSS} [%5p] %t (%F) - %m%n");

    properties.setProperty("log4j.appender.MyFile", "org.apache.log4j.RollingFileAppender");
    properties.setProperty("log4j.appender.MyFile.File", "my_example.log");
    properties.setProperty("log4j.appender.MyFile.MaxFileSize", "100KB");
    properties.setProperty("log4j.appender.MyFile.MaxBackupIndex", "1");
    properties.setProperty("log4j.appender.MyFile.layout",  "org.apache.log4j.PatternLayout");
    properties.setProperty("log4j.appender.MyFile.layout.ConversionPattern","%d{yyyy/MM/dd HH:mm:ss.SSS} [%5p] %t (%F) - %m%n");

    PropertyConfigurator.configure(properties);

    Logger logger = Logger.getLogger("MyFile");

    logger.fatal("This is a FATAL message.");
    logger.error("This is an ERROR message.");
    logger.warn("This is a WARN message.");
    logger.info("This is an INFO message.");
    logger.debug("This is a DEBUG message.");
    logger.trace("This is a TRACE message.");
}

}

Very Simple with the new version of the android studio 3.x.

Just copy the version that is less than the current version and add it explicitly with same version number as current version.

Example

Found versions 27.1.1, 27.1.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:exifinterface:27.1.0

Just copy the version com.android.support:exifinterface:27.1.0 and change it to com.android.support:exifinterface:27.1.1 so that it becomes equal to the current version you are using and add it to your gradle dependencies as following.

implementation 'com.android.support:exifinterface:27.1.1'

Note: Once you are done don't forget to click Sync now at the top of the editor.

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

If you are trying to transform a naive datetime into a datetime with timezone in django, here is my solution:

>>> import datetime
>>> from django.utils import timezone
>>> t1 = datetime.datetime.strptime("2019-07-16 22:24:00", "%Y-%m-%d %H:%M:%S")
>>> t1
    datetime.datetime(2019, 7, 16, 22, 24)
>>> current_tz = timezone.get_current_timezone()
>>> t2 = current_tz.localize(t1)
>>> t2
    datetime.datetime(2019, 7, 16, 22, 24, tzinfo=<DstTzInfo 'Asia/Shanghai' CST+8:00:00 STD>)
>>>

t1 is a naive datetime and t2 is a datetime with timezone in django's settings.

.NET Core 3 will have support for creating Windows desktop applications. I watched a demo of the technology yesterday during the .NET Conference.

This is the only blog post I could find, but it does illustrate the point: .NET Core 3 and Support for Windows Desktop Applications

i would recommend going to http://sourceforge.net/projects/py2exe/files/latest/download?source=files to download py2exe. Then make a python file named setup.py. Inside it, type

from distutils.core import setup
import py2exe
setup(console=['nameoffile.py'])

Save in your user folder Also save the file you want converted in that same folder

Run window's command prompt type in setup.py install py2exe

It should print many lines of code...

Next, open the dist folder.

Run the exe file.

If there are needed files for the program to work, move them to the folder

Copy/Send the dist folder to person.

Optional: Change the name of the dist folder

Hope it works!:)

there you go

$date = "04-15-2013";
$date1 = str_replace('-', '/', $date);
$tomorrow = date('m-d-Y',strtotime($date1 . "+1 days"));

echo $tomorrow;

this will output

04-16-2013

Using pyquaternion is extremely simple; to install it (while still in python), run in your console:

import pip;
pip.main(['install','pyquaternion'])

Once installed:

  from pyquaternion import Quaternion
  v = [3,5,0]
  axis = [4,4,1]
  theta = 1.2 #radian
  rotated_v = Quaternion(axis=axis,angle=theta).rotate(v)

$self has little to do with $, which is an alias for jQuery in this case. Some people prefer to put a dollar sign together with the variable to make a distinction between regular vars and jQuery objects.

example:

var self = 'some string';
var $self = 'another string';

These are declared as two different variables. It's like putting underscore before private variables.

A somewhat popular pattern is:

var foo = 'some string';
var $foo = $('.foo');

That way, you know $foo is a cached jQuery object later on in the code.

Here's a link to my tutorial, which walks you through :

• creating a JSON WCF Web Service from scratch (and the problems you'll want to avoid)
• adapting it to read/write SQL Server data
• getting an iOS 6 app to use the JSON servies.
• using the JSON web services with JavaScript

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

Official Specification: CSS 2.1: Chapter 5.5: Descendant Selectors

2.51 * 100 = 250.999999999997

The int() function simply truncates the number at the decimal point, giving 250. Use

int(round(2.51*100)) 

to get 251 as an integer. In general, floating point numbers cannot be represented exactly. One should therefore be careful of round-off errors. As mentioned, this is not a Python-specific problem. It's a recurring problem in all computer languages.

For command line (i.e. - makefile) users only:

1. When you install VC++ Express, it is 32-bit only. So, things go into C:\Program Files (x86).
2. Then, you decide to upgrade to 64-bit capabillities. So, you install the SDK. But it is 64-bit capable. So, things go into C:\Program Files.

You (like me) probably "tuned" your makefile to #1, above, via something like this:

MS_SDK_BASE_DOS := C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A
ENV_SET         := LIB="$(MS_SDK_BASE_DOS)\Lib\x64"

But, now, you need to change that tuning to #2, above, like this:

MS_SDK_BASE_DOS := C:\Program Files\Microsoft SDKs\Windows\v7.1

(Don't miss the "v7.0A" to "v7.1" change, as well.)

I had the same problem and I prefer not to replace the entire ArrayAdapter with a new instance continuously. Thus I have the AdapterHelper do the heavy lifting somewhere else.

Add this where you would normally (try to) call notify

new AdapterHelper().update((ArrayAdapter)adapter, new ArrayList<Object>(yourArrayList));
adapter.notifyDataSetChanged();

AdapterHelper class

public class AdapterHelper {
    @SuppressWarnings({ "rawtypes", "unchecked" })
    public void update(ArrayAdapter arrayAdapter, ArrayList<Object> listOfObject){
        arrayAdapter.clear();
        for (Object object : listOfObject){
            arrayAdapter.add(object);
        }
    }
}

Here are two functions to calculate distance and bearing, which are based on the code in previous messages and https://gist.github.com/jeromer/2005586 (added tuple type for geographical points in lat, lon format for both functions for clarity). I tested both functions and they seem to work right.

#coding:UTF-8
from math import radians, cos, sin, asin, sqrt, atan2, degrees

def haversine(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = pointA[0]
    lon1 = pointA[1]

    lat2 = pointB[0]
    lon2 = pointB[1]

    # convert decimal degrees to radians 
    lat1, lon1, lat2, lon2 = map(radians, [lat1, lon1, lat2, lon2]) 

    # haversine formula 
    dlon = lon2 - lon1 
    dlat = lat2 - lat1 
    a = sin(dlat/2)**2 + cos(lat1) * cos(lat2) * sin(dlon/2)**2
    c = 2 * asin(sqrt(a)) 
    r = 6371 # Radius of earth in kilometers. Use 3956 for miles
    return c * r


def initial_bearing(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = radians(pointA[0])
    lat2 = radians(pointB[0])

    diffLong = radians(pointB[1] - pointA[1])

    x = sin(diffLong) * cos(lat2)
    y = cos(lat1) * sin(lat2) - (sin(lat1)
            * cos(lat2) * cos(diffLong))

    initial_bearing = atan2(x, y)

    # Now we have the initial bearing but math.atan2 return values
    # from -180° to + 180° which is not what we want for a compass bearing
    # The solution is to normalize the initial bearing as shown below
    initial_bearing = degrees(initial_bearing)
    compass_bearing = (initial_bearing + 360) % 360

    return compass_bearing

pA = (46.2038,6.1530)
pB = (46.449, 30.690)

print haversine(pA, pB)

print initial_bearing(pA, pB)

The following function comes in three forms:

method = "mode" [default]: calculates the mode for a unimodal vector, else returns an NA
method = "nmodes": calculates the number of modes in the vector
method = "modes": lists all the modes for a unimodal or polymodal vector

modeav <- function (x, method = "mode", na.rm = FALSE)
{
  x <- unlist(x)
  if (na.rm)
    x <- x[!is.na(x)]
  u <- unique(x)
  n <- length(u)
  #get frequencies of each of the unique values in the vector
  frequencies <- rep(0, n)
  for (i in seq_len(n)) {
    if (is.na(u[i])) {
      frequencies[i] <- sum(is.na(x))
    }
    else {
      frequencies[i] <- sum(x == u[i], na.rm = TRUE)
    }
  }
  #mode if a unimodal vector, else NA
  if (method == "mode" | is.na(method) | method == "")
  {return(ifelse(length(frequencies[frequencies==max(frequencies)])>1,NA,u[which.max(frequencies)]))}
  #number of modes
  if(method == "nmode" | method == "nmodes")
  {return(length(frequencies[frequencies==max(frequencies)]))}
  #list of all modes
  if (method == "modes" | method == "modevalues")
  {return(u[which(frequencies==max(frequencies), arr.ind = FALSE, useNames = FALSE)])}  
  #error trap the method
  warning("Warning: method not recognised.  Valid methods are 'mode' [default], 'nmodes' and 'modes'")
  return()
}

Just hit on this when trying to solve this type of thing my self.

I did a selector that deals with the element after being something other than a p.

.here .is.the #selector h4 + * {...}

Hope this helps anyone who finds it :)

Just had the same error message, but when I was running a package.json with:

"scripts": {
    "build": "tsc -p ./src",
}

tsc is the command to run the TypeScript compiler.

I never had any issues with this project because I had TypeScript installed as a global module. As this project didn't include TypeScript as a dev dependency (and expected it to be installed as global), I had the error when testing in another machine (without TypeScript) and running npm install didn't fix the problem. So I had to include TypeScript as a dev dependency (npm install typescript --save-dev) to solve the problem.

The other features of CodeLens like: Show Bugs, Show Test Status, etc (other than Show Reference) might be useful.

However, if the only way to disable Show References is to disable CodeLens altogether.

Then, I guess I could do just that.

Furthermore, I would do like I always have, 'right-click on a member and choose Find all References or Ctrl+K, R'

If I wanted to know what references the member -- I too like not having any extra information crammed into my code, like extra white-space.

In short, uncheck Codelens...

I believe your "P" as the dataWithBytes param

NSData *keydata = [NSData dataWithBytes:P length:len];

should be "buf"

NSData *keydata = [NSData dataWithBytes:buf length:len];

since i2d_PrivateKey puts the pointer to the output buffer p at the end of the buffer and waiting for further input, and buf is still pointing to the beginning of your buffer.

The following code works for me where pkey is a pointer to an EVP_PKEY:

unsigned char *buf, *pp;
int len = i2d_PrivateKey(pkey, NULL);
buf = OPENSSL_malloc(len); 
pp = buf;
i2d_PrivateKey(pkey, &pp);

NSData* pkeyData = [NSData dataWithBytes:(const void *)buf length:len];
DLog(@"Private key in hex (%d): %@", len, pkeyData);

You can use an online converter to convert your binary data into base 64 (http://tomeko.net/online_tools/hex_to_base64.php?lang=en) and compare it to the private key in your cert file after using the following command and checking the output of mypkey.pem:

openssl pkcs12 -in myCert.p12 -nocerts -nodes -out mypkey.pem

I referenced your question and this EVP function site for my answer.

[Posted on behalf of fossuser] Thanks to "mu is too short" I was able to fix the bug. Here is my working code has been edited in for those looking for a nice example (since I couldn't find any others online).

    if(S_ISDIR(statbuf.st_mode))
      dircheck(dip, dit, statbuf, currentPath, depth, argv);
  }
  /*Changing back here is necessary because of how stat is done*/
    chdir("..");
    closedir(dip);
}

void dircheck(DIR *dip, struct dirent *dit, struct stat statbuf, 
          char currentPath[FILENAME_MAX], int depth, char *argv[]){
  int i = 0;

  strcat(currentPath, "/");
  strcat(currentPath, dit->d_name);

  /*If two directories exist at the same level the path
    is built wrong and needs to be corrected*/
  if((chdir(currentPath)) == -1){
    chdir("..");
    getcwd(currentPath, FILENAME_MAX);

    helper(dip, dit, statbuf, currentPath, depth, argv);
  }

  else{
    for(i =0; i < depth; i++)
      printf("    ");
    printf("%s (subdirectory)\n", dit->d_name);
    chdir(currentPath);

The "star sign" is only meaningful if there is something in front of it. If there isn't the tool (grep in this case) may just treat it as an error. For example:

'*xyz'    is meaningless
'a*xyz'   means zero or more occurrences of 'a' followed by xyz

I could successfully integrate Pagination in

spring-data-jpa-2.1.6

as follows.

@Query(
 value = “SELECT * FROM Users”, 
 countQuery = “SELECT count(*) FROM Users”, 
 nativeQuery = true)
Page<User> findAllUsersWithPagination(Pageable pageable);

Simply get it like this -

getFragmentManager() // This will also give you the SupportFragmentManager or FragmentManager based on which Fragment class you have extended - android.support.v4.app.Fragment OR android.app.Fragment.

OR

getActivity().getSupportFragmentManager();

in your Fragment's onActivityCreated() method and any method that is being called after onActivityCreated().

If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing.

var canvas = document.getElementById("myCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
var canvasData = ctx.getImageData(0, 0, canvasWidth, canvasHeight);

// That's how you define the value of a pixel //
function drawPixel (x, y, r, g, b, a) {
    var index = (x + y * canvasWidth) * 4;

    canvasData.data[index + 0] = r;
    canvasData.data[index + 1] = g;
    canvasData.data[index + 2] = b;
    canvasData.data[index + 3] = a;
}

// That's how you update the canvas, so that your //
// modification are taken in consideration //
function updateCanvas() {
    ctx.putImageData(canvasData, 0, 0);
}

Then, you can use it in this way :

drawPixel(1, 1, 255, 0, 0, 255);
drawPixel(1, 2, 255, 0, 0, 255);
drawPixel(1, 3, 255, 0, 0, 255);
updateCanvas();

For more information, you can take a look at this Mozilla blog post : http://hacks.mozilla.org/2009/06/pushing-pixels-with-canvas/

There's several different ways of doing this, with varying efficiency, depending on how good your query optimiser is, and the relative size of your two tables:

This is the shortest statement, and may be quickest if your phone book is very short:

SELECT  *
FROM    Call
WHERE   phone_number NOT IN (SELECT phone_number FROM Phone_book)

alternatively (thanks to Alterlife)

SELECT *
FROM   Call
WHERE  NOT EXISTS
  (SELECT *
   FROM   Phone_book
   WHERE  Phone_book.phone_number = Call.phone_number)

or (thanks to WOPR)

SELECT * 
FROM   Call
LEFT OUTER JOIN Phone_Book
  ON (Call.phone_number = Phone_book.phone_number)
  WHERE Phone_book.phone_number IS NULL

(ignoring that, as others have said, it's normally best to select just the columns you want, not '*')

I was facing the blurry text issue on Chrome but not on Firefox when I used transform: translate(-50%,-50%).

Well, I really tried a lot of workarounds like:

transform: perspective(1px);

filter: blur(0);

transform: translateZ(0);

backface-visibility: hidden;

None of these worked to me.

Finally, I made the height and width of the element even. It resolved the issue for me!!!

Note: It might depend from use case to use case. But surely worth a try!

Pragma is the HTTP/1.0 implementation and cache-control is the HTTP/1.1 implementation of the same concept. They both are meant to prevent the client from caching the response. Older clients may not support HTTP/1.1 which is why that header is still in use.

SelectedItem is an object. SelectedValue and SelectedValuePath are strings.

for example using the ListBox:

if you say give me listbox1.SelectedValue it will return the text of the currently selected item.

string value = listbox1.SelectedValue;

if you say give me listbox1.SelectedItem it will give you the entire object.

ListItem item = listbox1.SelectedItem;
string value = item.value;

If you want to add a modal and a tooltip without adding javascript or altering the tooltip function, you could also simply wrap an element around it:

<span data-toggle="modal" data-target="modal">
    <a data-toggle="tooltip" data-placement="top" title="Tooltip">
      Hover Me           
    </a>
</span>

At first check

Step-1: git remote -v
//if found git initialize then remove or skip step-2

Step-2: git remote rm origin
//Then configure your email address globally git

Step-3: git config --global user.email "[email protected]"

Step-4: git initial

Step-5: git commit -m "Initial Project"
//If already add project repo then skip step-6

Step-6: git remote add origin %repo link from bitbucket.org%

Step-7: git push -u origin master

One important point to note here, we should check if any files exists with the new filename.

suppose if b.kml file exists then renaming other file with the same filename leads to deletion of existing b.kml.

import os

if not os.path.exists('b.kml')
    os.rename('a.txt','b.kml')

Local classes have already been mentioned, but here is a way to let them appear even more as local functions, using an operator() overload and an anonymous class:

int main() {
    struct {
        unsigned int operator() (unsigned int val) const {
            return val<=1 ? 1 : val*(*this)(val-1);
        }
    } fac;

    std::cout << fac(5) << '\n';
}

I don't advise on using this, it's just a funny trick (can do, but imho shouldn't).

2014 Update:

With the rise of C++11 a while back, you can now have local functions whose syntax is a little reminiscient of JavaScript:

auto fac = [] (unsigned int val) {
    return val*42;
};

As eaon21 and monkey said, source map files basically turn minified code into its unminified version for debugging.

You can find the .map files here. Just add them into the same directory as the minified js files and it'll stop complaining. The reason they get fetched is the

/*
//@ sourceMappingURL=angular.min.js.map
*/

at the end of angular.min.js. If you don't want to add the .map files you can remove those lines and it'll stop the fetch attempt, but if you plan on debugging it's always good to keep the source maps linked.

I use django 1.7+ and python 2.7+, the solution above dose not work. And the input value in the form can be got use POST as below (use the same form above):

if form.is_valid():
  data = request.POST.get('my_form_field_name')
  print data

Hope this helps.

I had the same issue where my firewall was configured properly, TCP/IP was enabled in SQL Server Configuration Manager but I still could not access my SQL database from outside the computer hosting it. I found the solution was SQL Server Browser was disabled by default in Services (and no option was available to enable it in SQL Server Configuration Manager).

I enabled it by Control Panel > Administrative Tools > Services then double click on SQL Server Browser. In the General tab set the startup type to Automatic using the drop down list. Then go back into SQL Server Configuration Manager and check that the SQL Server Browser is enabled. Hope this helps.

This snippet i have used in my application to encode the URL so may this can help you to do the same.

Function URLEncode(ByVal str As String) As String
        Dim intLen As Integer
        Dim x As Integer
        Dim curChar As Long
        Dim newStr As String
        intLen = Len(str)
        newStr = ""

        For x = 1 To intLen
            curChar = Asc(Mid$(str, x, 1))

            If (curChar < 48 Or curChar > 57) And _
                (curChar < 65 Or curChar > 90) And _
                (curChar < 97 Or curChar > 122) Then
                                newStr = newStr & "%" & Hex(curChar)
            Else
                newStr = newStr & Chr(curChar)
            End If
        Next x

        URLEncode = newStr
    End Function

Java 7+

It's possible to take advantage of the StandardCharsets JDK class:

String str=...
InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(str).array());

BitConverter class can be used to convert a byte[] to string.

var convertedString = BitConverter.ToString(byteAttay);

Documentation of BitConverter class can be fount on MSDN

Python actually has a really sweet method that will 'return an iterator over the usable hosts in the network'. (setting strict to false iterates over all IPs)

For example:

import subprocess
import ipaddress

subnet = ipaddress.ip_network('192.168.1.0/24', strict=False)
for i in subnet.hosts():
    i = str(i)
    subprocess.call(["ping", "-c1", "-n", "-i0.1", "-W1", i])

The wait interval (-i0.1) may be important for automations, even a one second timeout (-t1) can take forever over a .0/24

EDIT: So, in order to track ICMP (ping) requests, we can do something like this:

#!/usr/bin/env python

import subprocess
import ipaddress

alive = []
subnet = ipaddress.ip_network('192.168.1.0/23', strict=False)
for i in subnet.hosts():
    i = str(i)
    retval = subprocess.call(["ping", "-c1", "-n", "-i0.1", "-W1", i])
    if retval == 0:
        alive.append(i)
for ip in alive:
    print(ip + " is alive") 

Which will return something like:

192.168.0.1 is alive
192.168.0.2 is alive
192.168.1.1 is alive
192.168.1.246 is alive

i.e. all of the IPs responding to ICMP ranging over an entire /23-- Pretty cool!

Instead of this LAST_INSERT_ID() try to use this one

mysqli_insert_id(connection)

This is a variance of need to reset body to original content. It doesn't deal with a form but I feel it might be of some use. If the original content was a ton of html, it is very difficult to string out the html and store it to a variable. Javascript does not take kindly to the line breaks that VS 2015/whatever allows. So I store original ton of html in default modal like this on page load:

var stylesString = $('#DefaultModal .modal-body').html();

Which allows me to to reuse this content when original default button for modal is pressed (there are other buttons that show other content in same modal).

$("#btnStyles").click(function () {
    //pass the data in the modal body adding html elements
    $('#DefaultModal .modal-body').html(stylesString);
 $('#DefaultModal').modal('show');
})

If I put an alert for the styleString variable it would have an endless string of all the html with no breaks but does it for me and keeps it out of VS editor.

Here is how it looks in Visual Studio inside default modal. Saved in the string variable whether automatic (.html) or by hand in VS, it would be one big line:

<div class="modal-body" id="modalbody">

Try my way :

robocopy.exe "Desktop\Test folder 1" "Desktop\Test folder 2" /XD "C:\Users\Steve\Desktop\Test folder 2\XXX dont touch" /MIR

Had to put /XD before /MIR while including the full Destination Source directly after /XD.

You can easily use this function to get the result:

function objetToArray($adminBar){
    $reflector = new ReflectionObject($adminBar);
    $nodes = $reflector->getProperties();
    $out = [];
    foreach ($nodes as $node) {
        $nod = $reflector->getProperty($node->getName());
        $nod->setAccessible(true);
        $out[$node->getName()] = $nod->getValue($adminBar);
    }
    return $out;
}

Use PHP 5 or later.

Reading the value (not the text) of a select:

var status = $("#Status").val();
var status = $("#Status")[0].value;
var status = $('#Status option:selected').val();

How to disable a select? in both variants, value can be changed using:

A

User can not interact with the dropdown. And he doesn't know what other options might exists.

$('#Status').prop('disabled', true);

B

User can see the options in the dropdown but all of them are disabled:

$('#Status option').attr('disabled', true);

In this case, $("#Status").val() will only work for jQuery versions smaller than 1.9.0. All other variants will work.

How to update a disabled select?

From code behind you can still update the value in your select. It is disabled only for users:

$("#Status").val(2);

In some cases you might need to fire events:

$("#Status").val(2).change();

You can use a Scanner with a FileInputStream instead of BufferedReader with a FileReader. For example:-

File file = new File("sample.txt");
try(Scanner sc = new Scanner(new FileInputStream(file))){
    int count=0;
    while(sc.hasNext()){
        sc.next();
        count++;
    }
System.out.println("Number of words: " + count);
}

Perhaps you need to know how urls are mapped too, since I suffered 404 for hours. There are two kinds of handlers handling requests. BeanNameUrlHandlerMapping and SimpleUrlHandlerMapping. When we defined a servlet-mapping, we are using SimpleUrlHandlerMapping. One thing we need to know is these two handlers share a common property called alwaysUseFullPath which defaults to false.

false here means Spring will not use the full path to mapp a url to a controller. What does it mean? It means when you define a servlet-mapping:

<servlet-mapping>
    <servlet-name>viewServlet</servlet-name>
    <url-pattern>/perfix/*</url-pattern>
</servlet-mapping>

the handler will actually use the * part to find the controller. For example, the following controller will face a 404 error when you request it using /perfix/api/feature/doSomething

@Controller()
@RequestMapping("/perfix/api/feature")
public class MyController {
    @RequestMapping(value = "/doSomething", method = RequestMethod.GET) 
    @ResponseBody
    public String doSomething(HttpServletRequest request) {
        ....
    }
}

It is a perfect match, right? But why 404. As mentioned before, default value of alwaysUseFullPath is false, which means in your request, only /api/feature/doSomething is used to find a corresponding Controller, but there is no Controller cares about that path. You need to either change your url to /perfix/perfix/api/feature/doSomething or remove perfix from MyController base @RequestingMapping.

You can subclass UINavigationController, set itself as the delegate, and set the backBarButtonItem in the delegate method navigationController:willShowViewController:animated:

@interface Custom_NavigationController : UINavigationController <UINavigationControllerDelegate>

@end

@implementation Custom_NavigationController

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.delegate = self;
}

#pragma mark - UINavigationControllerDelegate

- (void)navigationController:(UINavigationController *)navigationController     willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    viewController.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
}

@end

All you have to do is wrap your content inside a Grid Container tag, specify the spacing, then wrap the actual content inside a Grid Item tag.

 <Grid container spacing={24}>
    <Grid item xs={8}>
      <leftHeaderContent/>
    </Grid>

    <Grid item xs={3}>
      <rightHeaderContent/>
    </Grid>
  </Grid>

Also, I've struggled with material grid a lot, I suggest you checkout flexbox which is built into CSS automatically and you don't need any addition packages to use. Its very easy to learn.

Only one app is automatically initialized. Others have to manually initialized as follows:

AngularJS API

I wanted 2 way conversion, and I wanted to use Python 3 format() support to be most pythonic. Maybe try datasize library module? https://pypi.org/project/datasize/

$ pip install -qqq datasize
$ python
...
>>> from datasize import DataSize
>>> 'My new {:GB} SSD really only stores {:.2GiB} of data.'.format(DataSize('750GB'),DataSize(DataSize('750GB') * 0.8))
'My new 750GB SSD really only stores 558.79GiB of data.'

[id^=product]

^= indicates "starts with". Conversely, $= indicates "ends with".

The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.

See the specs for full information.

There is foreach loop in php. You have to traverse the array.

foreach($array as $key => $value)
{
  echo $key." has the value". $value;
}

If you simply want to add commas between values, consider using implode

$string=implode(",",$array);
echo $string;

I don't like having to change my signature to use the HttpCreateResponse type, so I came up with a little bit of an extended solution to hide that.

public class HttpActionResult : IHttpActionResult
{
    public HttpActionResult(HttpRequestMessage request) : this(request, HttpStatusCode.OK)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code) : this(request, code, null)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code, object result)
    {
        Request = request;
        Code = code;
        Result = result;
    }

    public HttpRequestMessage Request { get; }
    public HttpStatusCode Code { get; }
    public object Result { get; }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        return Task.FromResult(Request.CreateResponse(Code, Result));
    }
}

You can then add a method to your ApiController (or better your base controller) like this:

protected IHttpActionResult CustomResult(HttpStatusCode code, object data) 
{
    // Request here is the property on the controller.
    return new HttpActionResult(Request, code, data);
}

Then you can return it just like any of the built in methods:

[HttpPost]
public IHttpActionResult Post(Model model)
{
    return model.Id == 1 ?
                Ok() :
                CustomResult(HttpStatusCode.NotAcceptable, new { 
                    data = model, 
                    error = "The ID needs to be 1." 
                });
}

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

Similar to the above solutions I used @Input() in a directive and able to pass multiple arrays of values in the directive.

selector: '[selectorHere]',

@Input() options: any = {};

Input.html

<input selectorHere [options]="selectorArray" />

Array from TS file

selectorArray= {
  align: 'left',
  prefix: '$',
  thousands: ',',
  decimal: '.',
  precision: 2
};

I got this from some forum. I hope it will be useful for you.

<script type="text/javascript">
 function validateFileExtension(fld) {
    if(!/(\.bmp|\.gif|\.jpg|\.jpeg)$/i.test(fld.value)) {
        alert("Invalid image file type.");      
        fld.form.reset();
        fld.focus();        
        return false;   
    }   
    return true; 
 } </script> </head>

I think things would be easier if you code your success function to load the appropriate page instead of returning true or false.

For example instead of returning true you could do:

window.location="appropriate page";

That way when the success function is called the page gets redirected.

I use this class for Audio play. If your audio location is raw folder.

Call method for play:

new AudioPlayer().play(mContext, getResources().getIdentifier(alphabetItemList.get(mPosition)
                        .getDetail().get(0).getAudio(),"raw", getPackageName()));

AudioPlayer.java class:

public class AudioPlayer {

    private MediaPlayer mMediaPlayer;

    public void stop() {
        if (mMediaPlayer != null) {
            mMediaPlayer.release();
            mMediaPlayer = null;
        }
    }
    // mothod for raw folder (R.raw.fileName)
    public void play(Context context, int rid){
        stop();

        mMediaPlayer = MediaPlayer.create(context, rid);
        mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mediaPlayer) {
                stop();
            }
        });

        mMediaPlayer.start();
    }

    // mothod for other folder 
    public void play(Context context, String name) {
        stop();

        //mMediaPlayer = MediaPlayer.create(c, rid);
        mMediaPlayer = MediaPlayer.create(context, Uri.parse("android.resource://"+ context.getPackageName()+"/your_file/"+name+".mp3"));
        mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mediaPlayer) {
                stop();
            }
        });

        mMediaPlayer.start();
    }

}

Apart from a database, you can also have following options to save user related settings

1. registry under HKEY_CURRENT_USER

2. in a file in AppData folder

3. using Settings file in WPF and by setting its scope as User

Because os.path.abspath = os.path.dirname + os.path.basename does not hold. we rather have

os.path.dirname(filename) + os.path.basename(filename) == filename

Both dirname() and basename() only split the passed filename into components without taking into account the current directory. If you want to also consider the current directory, you have to do so explicitly.

To get the dirname of the absolute path, use

os.path.dirname(os.path.abspath(__file__))

Make sure Match Case is selected with Use Regular Expression so this matches. [A-Z]* If match case is not selected, this matches all letters.

var newTH = document.createElement('th');
newTH.setAttribute("onclick", "removeColumn(#)");
newTH.setAttribute("id", "#");

function removeColumn(#){
// remove column #
}

git diff for unstaged changes.

git diff --cached for staged changes.

git diff HEAD for both staged and unstaged changes.

I solved it with a custom data tag, because a title attribute is required anyway.

$("[data-tooltip]").each(function(i, e) {
    var tag = $(e);
    if (tag.is("[title]") === false) {
        tag.attr("title", "");
    }
});

$(document).tooltip({
    items: "[data-tooltip]",
    content: function () {
        return $(this).attr("data-tooltip");
    }
});

Like this it is html conform and the tooltips are only shown for wanted tags.

Short answer - no.

You will only be charged for the time that your instance is up and running, in hour increments. If you are using other services in conjunction you may be charged for those but it would be separate from your server instance.

Put the export declaration in ~/.bashrc. My .bashrc contains this:

export PATH=/var/lib/gems/1.8/bin:/home/fraxtil/.bin:$PATH

You can include the branch to track when setting up remotes, to keep things working as you might expect:

git remote add --track master origin [email protected]:group/project.git   # git
git remote add --track master origin [email protected]:group/project.git   # git w/IP
git remote add --track master origin http://github.com/group/project.git   # http
git remote add --track master origin http://172.16.1.100/group/project.git # http w/IP
git remote add --track master origin /Volumes/Git/group/project/           # local
git remote add --track master origin G:/group/project/                     # local, Win

This keeps you from having to manually edit your git config or specify branch tracking manually.

In IntelliJ IDEA this happened to me when I imported a project that had been working fine and running with Java 1.7. I apparently hadn't notified IntelliJ that java 1.7 had been installed on my machine, and it wasn't finding my $JAVA_HOME.

On a Mac, this is resolved by:

Right clicking on the module | Module Settings | Project

and adding the 1.7 SDK by selecting "New" in the Project SDK.

Then go to the main IntelliJ IDEA menu | Preferences | Maven | Runner

and select the correct JRE. In my case it updated correctly Use Project SDK, which was now 1.7.

OMG!!! YES, WE CAN DO THAT!!! I was going to kill myself after severe 24 hours of investigating and discovering... But I've found "fresh" solution!

// "cheat" with Java reflection to gain access to TelephonyManager's
// ITelephony getter
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
telephonyService = (ITelephony)m.invoke(tm);

all all all of hundreds of people who wants to develop their call-control software visit this start point

there is a project. and there are important comments (and credits)

briefly: copy aidl file, add permissions to manifest, copy-paste source for telephony management )))

Some more info for you. AT commands you can send only if you are rooted. Than you can kill system process and send commands but you will need a reboot to allow your phone to receive and send calls =)))

I'm very hapy =) Now my Shake2MuteCall will get an update !

You have to supply to the JLabel an Icon implementation (i.e ImageIcon). You can do it trough the setIcon method, as in your question, or through the JLabel constructor:

Image image=GenerateImage.toImage(true);  //this generates an image file
ImageIcon icon = new ImageIcon(image); 
JLabel thumb = new JLabel();
thumb.setIcon(icon);

I recommend you to read the Javadoc for JLabel, Icon, and ImageIcon. Also, you can check the How to Use Labels Tutorial, for more information.

I guess a EXIT_ON_CLOSE

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

before System.exit(0) is better since you can write a Window Listener to make some cleaning operations before actually leaving the app.

That window listener allows you to defined:

public void windowClosing(WindowEvent e) {
    displayMessage("WindowListener method called: windowClosing.");
    //A pause so user can see the message before
    //the window actually closes.
    ActionListener task = new ActionListener() {
        boolean alreadyDisposed = false;
        public void actionPerformed(ActionEvent e) {
            if (frame.isDisplayable()) {
                alreadyDisposed = true;
                frame.dispose();
            }
        }
    };
    Timer timer = new Timer(500, task); //fire every half second
    timer.setInitialDelay(2000);        //first delay 2 seconds
    timer.setRepeats(false);
    timer.start();
}

public void windowClosed(WindowEvent e) {
    //This will only be seen on standard output.
    displayMessage("WindowListener method called: windowClosed.");
}

I solved the error by modifying the following property in hibernate.cfg.xml

  <property name="hibernate.hbm2ddl.auto">validate</property>

Earlier, the table was getting deleted each time I ran the program and now it doesnt, as hibernate only validates the schema and does not affect changes to it.

We managed installation of netbeans 6.8 under windows 8 successfully the following way:

• Don't execute but unzip netbeans-6.8-ml-windows.exe with 7zip (or other unzipper) in an emtpy folder
• execute cmd.exe as administrator
• cd to the folder in which you unzipped the installer
• execute 'java org.netbeans.installer.Installer'

-> installation executes without any errors

In python 3, to get text output:

import io
import urllib.request

response = urllib.request.urlopen("http://google.com")
text = io.TextIOWrapper(response)

Here you have an example

$("#profiles-thread").select2({
    minimumInputLength: 2,
    tags: [],
    ajax: {
        url: URL,
        dataType: 'json',
        type: "GET",
        quietMillis: 50,
        data: function (term) {
            return {
                term: term
            };
        },
        results: function (data) {
            return {
                results: $.map(data, function (item) {
                    return {
                        text: item.completeName,
                        slug: item.slug,
                        id: item.id
                    }
                })
            };
        }
    }
});

It's quite easy

You can make use of java.util.Date instead of Timestamp :

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

In Swift try this,

navigationController?.isNavigationBarHidden = true  //Hide
navigationController?.isNavigationBarHidden = false //Show

or

navigationController?.setNavigationBarHidden(true, animated: true) //Hide
navigationController?.setNavigationBarHidden(false, animated: true) //Show

To me, it sounds like you want to create a new attribute? Do you want

<option value="2" value2="somethingElse">...

To do this, you can do

$(your selector).attr('value2', 'the value');

And then to retrieve it, you can use

$(your selector).attr('value2')

It's not going to be valid code, but I guess it does the job.

Generic

   public static DataTable ToTableValuedParameter<T, TProperty>(this IEnumerable<T> list, Func<T, TProperty> selector)
    {
        var tbl = new DataTable();
        tbl.Columns.Add("Id", typeof(T));

        foreach (var item in list)
        {
            tbl.Rows.Add(selector.Invoke(item));

        }

        return tbl;

    }

For a quick solution, I usually do like this.

This approach will allow the user to enter date in any format they like in the textbox, and finally format in mm/dd/yyyy format when he is done editing. So it is quite flexible:

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    If TextBox1.Text <> "" Then
        If IsDate(TextBox1.Text) Then
            TextBox1.Text = Format(TextBox1.Text, "mm/dd/yyyy")
        Else
            MsgBox "Please enter a valid date!"
            Cancel = True
        End If
    End If
End Sub

However, I think what Sid developed is a much better approach - a full fledged date picker control.

use below code

 Task.WaitAll(Task.Run(async () => await GetResponse<MyObject>("my url")));

None of the solution are working currently. Here is my solution. You can add prefixes.

box-shadow: inset 0px 0px 0px 0px red;

import subprocess

filepath="D:/path/to/batch/myBatch.bat"
p = subprocess.Popen(filepath, shell=True, stdout = subprocess.PIPE)

stdout, stderr = p.communicate()
print p.returncode # is 0 if success

This will also restore the staging directory:

git stash apply --index

Convert by Number Class:-

Eg:

var n = Number("103");
console.log(n+1)

Output: 104

Note:- Number is class. When we pass string, then constructor of Number class will convert it.

In HTML:

<input type="submit" id="btnSubmit" name="btnSubmit" value="Save Changes" />
<input type="submit" id="btnDelete" name="btnDelete" value="Delete" />

In PHP:

if (isset($_POST["btnSubmit"])){
  // "Save Changes" clicked
} else if (isset($_POST["btnDelete"])){
  // "Delete" clicked
}

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

After trying these solutions I still wasn't satisfied but I found a solution in this article and it works in Chrome, Firefox, Opera, Safari, IE8+

#divId {

  display: block;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  background: url(http://notrealdomain2.com/newbanner.png) no-repeat;
  width: 180px; /* Width of new image */
  height: 236px; /* Height of new image */
  padding-left: 180px; /* Equal to width of new image */

}

Thanks all for the help - turns out it was a WiX issue.

When the Product ID GUID was left explicit & hardcoded as in the question, the resulting .msi had no ProductCode property but a Product ID property instead when inspected with orca.

Once I changed the GUID to '*' to auto-generate, the ProductCode showed up and all works fine with syntax confirmed by the other answers.

The AWS support pointed a simpler solution. It's basically the same idea proposed by @Vivek M. Chawla, with a more simple implementation.

AWS S3:

1. Create a Bucket named with your full domain, like aws.example.com
2. On the bucket properties, select Redirect all requests to another host name and enter your URL: https://myaccount.signin.aws.amazon.com/console/

AWS Route53:

1. Create a record set type A. Change Alias to Yes. Click on Alias Target field and select the S3 bucket you created in the previous step.

Reference: How to redirect domains using Amazon Web Services

AWS official documentation: Is there a way to redirect a domain to another domain using Amazon Route 53?

I'm assuming you're using DB2 for z/OS, which unfortunately (for whatever reason, I never really understood why) doesn't support using a values-list where a full-select would be appropriate.

You can use a select like below. It's a little unwieldy, but it works:

INSERT INTO tableName (col1, col2, col3, col4, col5) 
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1

Your statement would work on DB2 for Linux/Unix/Windows (LUW), at least when I tested it on my LUW 9.7.

It is simple: if recv() returns 0 bytes; you will not receive any more data on this connection. Ever. You still might be able to send.

It means that your non-blocking socket have to raise an exception (it might be system-dependent) if no data is available but the connection is still alive (the other end may send).

To get mod_rewrite to work for me in Apache 2.4, I had to add the "Require all granted" line below.

<Directory /var/www>
   # Required if running apache > 2.4
   Require all granted

   RewriteEngine on 
   RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L] 
 </Directory>

supposedly a similar requirement exists for Apache 2.2 as well, if you're using that:

<Directory /var/www>
   # Required if running apache 2.2
   Order allow,deny
   Allow from all

   RewriteEngine on 
   RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L] 
 </Directory>

Note that an ErrorDocument 404 directive can sometimes override these things as well, so if it's not working try commenting out your ErrorDocument directive and see if it works. The above example can be used to ensure a site isn't served from cache by including a subfolder in the path, though the files reside at the root of the server.

Angular 6.1.0+ Answer

Use the built-in keyvalue-pipe like this:

<div *ngFor="let item of myObject | keyvalue">
    Key: <b>{{item.key}}</b> and Value: <b>{{item.value}}</b>
</div>

or like this:

<div *ngFor="let item of myObject | keyvalue:mySortingFunction">
    Key: <b>{{item.key}}</b> and Value: <b>{{item.value}}</b>
</div>

where mySortingFunction is in your .ts file, for example:

mySortingFunction = (a, b) => {
  return a.key > b.key ? -1 : 1;
}

Stackblitz: https://stackblitz.com/edit/angular-iterate-key-value

You won't need to register this in any module, since Angular pipes work out of the box in any template.

It also works for Javascript-Maps.

cmd.exe is located in different locations in different versions of Windows. To avoid needing the location of cmd.exe, you can use the command moogs wrote without calling "cmd.exe /C".

Here's an example that worked for me:

1. Open Command Prompt
2. Change directory to where your application's .exe file is located.
3. Execute the following command: runas /user:domain\username Application.exe

So the final step will look something like this in Command Prompt:

C:\Projects\MyProject\bin\Debug>runas /user:domain\username Application.exe

Note: the domain name was required in my situation.

to stop a docker process and release the ports, first use ctrl-c to leave the exit the container then use docker ps to find the list of running containers. Then you can use the docker container stop to stop that process and release its ports. The container name you can find from the docker ps command which gives the name in the name column. Hope this solves your queries....

If someone wants to do the same thing with Pandas

import pandas as pd
import sqlite3
conn = sqlite3.connect("db.sqlite3")
table = pd.read_sql_query("SELECT name FROM sqlite_master WHERE type='table'", conn)
print(table)

ALTER TABLE users
  ADD COLUMN "priv_user" BOOLEAN DEFAULT FALSE;

you can also directly specify NOT NULL

ALTER TABLE users
  ADD COLUMN "priv_user" BOOLEAN NOT NULL DEFAULT FALSE;

UPDATE: following is only true for versions before postgresql 11.

As Craig mentioned on filled tables it is more efficient to split it into steps:

ALTER TABLE users ADD COLUMN priv_user BOOLEAN;
UPDATE users SET priv_user = 'f';
ALTER TABLE users ALTER COLUMN priv_user SET NOT NULL;
ALTER TABLE users ALTER COLUMN priv_user SET DEFAULT FALSE;

The stdout stream is line buffered by default, so will only display what's in the buffer after it reaches a newline (or when it's told to). You have a few options to print immediately:

Print to stderrinstead using fprintf (stderr is unbuffered by default):

fprintf(stderr, "I will be printed immediately");

Flush stdout whenever you need it to using fflush:

printf("Buffered, will be flushed");
fflush(stdout); // Will now print everything in the stdout buffer

Edit: From Andy Ross's comment below, you can also disable buffering on stdout by using setbuf:

setbuf(stdout, NULL);

or its secure version setvbuf as explained here

setvbuf(stdout, NULL, _IONBF, 0); 

You may also use all() method to get array of selected attributes.

$test=test::select('id')->where('id' ,'>' ,0)->all();

document.getElementById('myRadio') returns you the DOM element, i'll reference it as elem in this answer.

elem.checked accesses the property named checked of the DOM element. This property is always a boolean.

When writing HTML you use checked="checked" in XHTML; in HTML you can simply use checked. When setting the attribute (this is done via .setAttribute('checked', 'checked')) you need to provide a value since some browsers consider an empty value being non-existent.

However, since you have the DOM element you have no reason to set the attribute since you can simply use the - much more comfortable - boolean property for it. Since non-empty strings are considered true in a boolean context, setting elem.checked to 'checked' or anything else that is not a falsy value (even 'false' or '0') will check the checkbox. There is not reason not to use true and false though so you should stick with the proper values.

Write below code into your MainActivity file after setContentView(R.layout.activity_main);

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

And below import statement into your java file.

import android.os.StrictMode;

Best solution for this is to download and install VCforPython2.7 from https://www.microsoft.com/en-us/download/details.aspx?id=44266

Then try pip install numpy

You could also set onclick to call your function like this:

foo.onclick = function() { callYourJSFunction(arg1, arg2); };

This way, you can pass arguments too. .....

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

FILE *fp;
char* str = "string";
int x = 10;

fp=fopen("test.txt", "w");
if(fp == NULL)
    exit(-1);
fprintf(fp, "This is a string which is written to a file\n");
fprintf(fp, "The string has %d words and keyword %s\n", x, str);
fclose(fp);

Newer versions of JQuery mobile API (I guess its newer than 1.5) require adding 'back' button explicitly in header or bottom of each page.

So, try adding this in your page div tags:

data-add-back-btn="true"
data-back-btn-text="Back"

Example:

<div data-role="page" id="page2" data-add-back-btn="true" data-back-btn-text="Back">

In addition, this problem also occurs when you add a user generated story (where you do not use og:image). For example:

POST /me/cookbook:eat?
  recipe=http://www.example.com/recipes/pizza/&
  image[0][url]=http://www.example.com/recipes/pizza/pizza.jpg&
  image[0][user_generated]=true&
  access_token=VALID_ACCESS_TOKEN

The above will only work with http and not with https. If you use https, you will get an error that says: Attached image () failed to upload

Code for adding fragment

public Fragment getItem(int position) {

    switch (position){
        case 0:
            return new Fragment1();

        case 1:
            return new Fragment2();

        case 2:
            return new Fragment3();

        case 3:
            return new Fragment4();

        default:
            break;
    }

    return null;
}

Create an xml file for each fragment say for Fragment1, use fragment_one.xml as layout file, use the below code in Fragment1 java file.

public class Fragment1 extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_one, container, false);

        return view;

    }
}

Later you can make necessary corrections.. It worked for me.

There are different ways to achieve it. The latest approach is using CardView for each ListItem component. Here are some steps.

1. Create a layout resource file; let's name it "listitem.xml
2. Copy and paste the under enclosed Listitem.xml layout body into it.
3. Create RowItem class for each listitem data; later you will instantiate this to assign values for each list item. Check Code below, RowItem.class.
4. Create a custom ListAdapter; let's name it ListAdapter.class, and inflate this (#1) list item layout for each list item (Check the second code snippet for this one)
5. Set this adapter (#3) the way you set default adapters inside an activity the listview belongs to. maybe the only difference would be you first have to instantiate RowItem class with values and add RowItem object to your adapter then notify your adapter that the data is changed.

RowItem.Class

public class RowItem {
    private String heading;
    private String subHeading;
    private int smallImageName;
    private String datetime;
    private int count;

    public void setHeading( String theHeading ) {
        this.heading = theHeading;
    }

    public String getHeading() {
        return this.heading;
    }
    public void setSubHeading( String theSubHeading ) {

        this.subHeading = theSubHeading;

    }

    public String getSubHeading( ) {

        return this.subHeading;

    }

    public void setSmallImageName(int smallName) {

        this.smallImageName = smallName;

    }

    public int getSmallImageName() {

        return this.smallImageName;

    }

    public void setDate(String datetime) {
        this.datetime = datetime;
    }

    public String getDate() {
        return this.datetime;
    }

    public void setCount(int count) {
        this.count = count;
    }

    public int getCount() {
        return this.count;
    }

}

Sample ListAdapter

public class ListAdapter extends BaseAdapter {
    private ArrayList<RowItem> singleRow;
    private LayoutInflater thisInflater;

    public ListAdapter(Context context, ArrayList<RowItem> aRow){

        this.singleRow = aRow;
        thisInflater = ( LayoutInflater.from(context) );
    }
    @Override
    public int getCount() {
        return singleRow.size();    }

    @Override
    public Object getItem(int position) {
        return singleRow.get( position );    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View view, ViewGroup parent) {

        if (view == null) {
            view = thisInflater.inflate( R.layout.mylist2, parent, false );
            //set listview objects here
            //example

            TextView titleText = (TextView) view.findViewById(R.id.titleoflistview);
           
            RowItem currentRow = (RowItem) getItem(position);
            
            titleText.setText( currentRow.getHeading() );
          
        }

        return view;

//        LayoutInflater inflater=.getLayoutInflater();
//        View rowView=inflater.inflate(R.layout.mylist, null,true);
//

//        titleText.setText(maintitle[position]);
//        subtitleText.setText(subtitle[position]);

//        return null;

    };
}

the solution from millhouse is not working anymore with recent version of mockito

This solution work with java 8 and mockito 2.2.9

where ArgumentMatcher is an instanceof org.mockito.ArgumentMatcher

public class ClassOrSubclassMatcher<T> implements ArgumentMatcher<Class<T>> {

   private final Class<T> targetClass;

    public ClassOrSubclassMatcher(Class<T> targetClass) {
        this.targetClass = targetClass;
    }

    @Override
    public boolean matches(Class<T> obj) {
        if (obj != null) {
            if (obj instanceof Class) {
                return targetClass.isAssignableFrom( obj);
            }
        }
        return false;
    }
}

And the use

when(a.method(ArgumentMatchers.argThat(new ClassOrSubclassMatcher<>(A.class)))).thenReturn(b);

Just use the method message.setRecipients with multiple addresses separated by commas:

message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected],[email protected],[email protected]"));

message.setRecipients(Message.RecipientType.CC, InternetAddress.parse("[email protected],[email protected],[email protected]"));

works fine with only one address too

message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));

This approach works for me in Node.js, Is there any problem with this one?

File 'include.js':

fs = require('fs');

File 'main.js':

require('./include.js');

fs.readFile('./file.json', function (err, data) {
    if (err) {
        console.log('ERROR: file.json not found...')
    } else {
        contents = JSON.parse(data)
    };
})

1) react-router > V5 useHistory hook:

If you have React >= 16.8 and functional components you can use the useHistory hook from react-router.

import React from 'react';
import { useHistory } from 'react-router-dom';

const YourComponent = () => {
    const history = useHistory();

    const handleClick = () => {
        history.push("/path/to/push");
    }

    return (
        <div>
            <button onClick={handleClick} type="button" />
        </div>
    );
}

export default YourComponent;

2) react-router > V4 withRouter HOC:

As @ambar mentioned in the comments, React-router has changed their code base since their V4. Here are the documentations - official, withRouter

import React, { Component } from 'react';
import { withRouter } from "react-router-dom";

class YourComponent extends Component {
    handleClick = () => {
        this.props.history.push("path/to/push");
    }

    render() {
        return (
            <div>
                <button onClick={this.handleClick} type="button">
            </div>
        );
    };
}

export default withRouter(YourComponent);

3) React-router < V4 with browserHistory

You can achieve this functionality using react-router BrowserHistory. Code below:

import React, { Component } from 'react';
import { browserHistory } from 'react-router';

export default class YourComponent extends Component {
    handleClick = () => {
        browserHistory.push('/login');
    };

    render() {
        return (
            <div>
                <button onClick={this.handleClick} type="button">
            </div>
        );
    };
}

4) Redux connected-react-router

If you have connected your component with redux, and have configured connected-react-router all you have to do is this.props.history.push("/new/url"); ie, you don't need withRouter HOC to inject history to the component props.

// reducers.js
import { combineReducers } from 'redux';
import { connectRouter } from 'connected-react-router';

export default (history) => combineReducers({
    router: connectRouter(history),
    ... // rest of your reducers
});


// configureStore.js
import { createBrowserHistory } from 'history';
import { applyMiddleware, compose, createStore } from 'redux';
import { routerMiddleware } from 'connected-react-router';
import createRootReducer from './reducers';
...
export const history = createBrowserHistory();

export default function configureStore(preloadedState) {
    const store = createStore(
        createRootReducer(history), // root reducer with router state
        preloadedState,
        compose(
            applyMiddleware(
                routerMiddleware(history), // for dispatching history actions
                // ... other middlewares ...
            ),
        ),
    );

    return store;
}


// set up other redux requirements like for eg. in index.js
import { Provider } from 'react-redux';
import { Route, Switch } from 'react-router';
import { ConnectedRouter } from 'connected-react-router';
import configureStore, { history } from './configureStore';
...
const store = configureStore(/* provide initial state if any */)

ReactDOM.render(
    <Provider store={store}>
        <ConnectedRouter history={history}>
            <> { /* your usual react-router v4/v5 routing */ }
                <Switch>
                    <Route exact path="/yourPath" component={YourComponent} />
                </Switch>
            </>
        </ConnectedRouter>
    </Provider>,
    document.getElementById('root')
);


// YourComponent.js
import React, { Component } from 'react';
import { connect } from 'react-redux';
...

class YourComponent extends Component {
    handleClick = () => {
        this.props.history.push("path/to/push");
    }

    render() {
        return (
          <div>
            <button onClick={this.handleClick} type="button">
          </div>
        );
      }
    };

}

export default connect(mapStateToProps = {}, mapDispatchToProps = {})(YourComponent);

Use docker ps to get the container id.

Then docker inspect -f '{{ .Mounts }}' containerid

Example:

terminal 1

$ docker run -it -v /tmp:/tmp ubuntu:14.04 /bin/bash

terminal 2

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
ddb7b55902cc        ubuntu:14.04        "/bin/bash"         About a minute ago   Up About a minute                       distracted_banach   

$ docker inspect -f "{{ .Mounts }}" ddb7
map[/tmp:/tmp]

The output

map[/tmp:/tmp] 

is, apparently, due to the use of the Go language to implement the docker command tools.

The docker inspect command without the -f format is quite verbose. Since it is JSON you could pipe it to python or nodejs and extract whatever you needed.

docker history <image name> will show the layers baked into an image. Unfortunately, docker history seems hobbled by its formatting and lack of options to choose what is displayed.

You can choose terse and verbose formats, via the --no-trunc flag.

Sounds like you want:

var movies = _db.Movies.Where(p => p.Genres.Intersect(listOfGenres).Any());

Sku is an int, can't be defaulted to string "sku". Please check Optional URI Parameters and Default Values

BTW, one of the reason of symbol not found error may be that your IDE imported android.R; class instead of yours one. Just change import android.R; to import your.namespace.R;

So 2 basic things to get string visible in the different class:

//make sure you are importing the right R class
import your.namespace.R;

//don't forget about the context
public void some_method(Context context) {
   context.getString(R.string.YOUR_STRING);
}

static T DeserializeXml<T>(string sourceXML) where T : class
{
    var serializer = new XmlSerializer(typeof(T));
    T result = null;

    using (TextReader reader = new StringReader(sourceXML))
    {
        result = (T) serializer.Deserialize(reader);
    }

    return result;
}

It's much easier (and faster) to get this information by only parsing the output of ver:

@echo off
setlocal
for /f "tokens=4-5 delims=. " %%i in ('ver') do set VERSION=%%i.%%j
if "%version%" == "10.0" echo Windows 10
if "%version%" == "6.3" echo Windows 8.1
if "%version%" == "6.2" echo Windows 8.
if "%version%" == "6.1" echo Windows 7.
if "%version%" == "6.0" echo Windows Vista.
rem etc etc
endlocal

This table on MSDN documents which version number corresponds to which Windows product version (this is where you get the 6.1 means Windows 7 information from).

The only drawback of this technique is that it cannot distinguish between the equivalent server and consumer versions of Windows.

StartsWith

a) left(@edition, 15) = 'Express Edition'
b) charindex('Express Edition', @edition) = 1

Contains

charindex('Express Edition', @edition) >= 1

Examples

left function

set @isExpress = case when left(@edition, 15) = 'Express Edition' then 1 else 0 end

iif function (starting with SQL Server 2012)

set @isExpress = iif(left(@edition, 15) = 'Express Edition', 1, 0);

charindex function

set @isExpress = iif(charindex('Express Edition', @edition) = 1, 1, 0);

MVC i have two input text 1: number of day 2: datetime picker

 @Html.TextBox("HeaderINVID", null, new { @id = "HeaderINVID", @type = "number", @class = "form-control", autocomplete = "off", placeholder = "Day Count " })

  @Html.TextBox("HeaderINVDT", null, new { id = "HeaderINVDT", @class = "form-control format-picker", autocomplete = "off", placeholder = " Date" })

javascipt

to calculate number from date use

    $("#HeaderINVID").bind("keyup", function (e) {
        var INVID = $("#HeaderINVID").val();
        var date = moment()
            .add(INVID, 'd')
            .toDate(); 
        $("#HeaderINVDT").val(moment(date).format('YYYY-MM-DD')) ;
    })

to calculate number of days between two dates use

  $("#HeaderINVDT").bind('change', function (e) {
        var StDT = moment($("#HeaderINVDT").val()).startOf('day');
        var NODT = moment().startOf('day');
        $("#HeaderINVID").val(StDT.diff(NODT, 'days'));
    })

I think that LINQ join clause isn't the correct solution to this problem, because of join clause purpose isn't to accumulate data in such way as required for this task solution. The code to merge created separate collections becomes too complicated, maybe it is OK for learning purposes, but not for real applications. One of the ways how to solve this problem is in the code below:

class Program
{
    static void Main(string[] args)
    {
        List<FirstName> firstNames = new List<FirstName>();
        firstNames.Add(new FirstName { ID = 1, Name = "John" });
        firstNames.Add(new FirstName { ID = 2, Name = "Sue" });

        List<LastName> lastNames = new List<LastName>();
        lastNames.Add(new LastName { ID = 1, Name = "Doe" });
        lastNames.Add(new LastName { ID = 3, Name = "Smith" });

        HashSet<int> ids = new HashSet<int>();
        foreach (var name in firstNames)
        {
            ids.Add(name.ID);
        }
        foreach (var name in lastNames)
        {
            ids.Add(name.ID);
        }
        List<FullName> fullNames = new List<FullName>();
        foreach (int id in ids)
        {
            FullName fullName = new FullName();
            fullName.ID = id;
            FirstName firstName = firstNames.Find(f => f.ID == id);
            fullName.FirstName = firstName != null ? firstName.Name : string.Empty;
            LastName lastName = lastNames.Find(l => l.ID == id);
            fullName.LastName = lastName != null ? lastName.Name : string.Empty;
            fullNames.Add(fullName);
        }
    }
}
public class FirstName
{
    public int ID;

    public string Name;
}

public class LastName
{
    public int ID;

    public string Name;
}
class FullName
{
    public int ID;

    public string FirstName;

    public string LastName;
}

If real collections are large for HashSet formation instead foreach loops can be used the code below:

List<int> firstIds = firstNames.Select(f => f.ID).ToList();
List<int> LastIds = lastNames.Select(l => l.ID).ToList();
HashSet<int> ids = new HashSet<int>(firstIds.Union(LastIds));//Only unique IDs will be included in HashSet

Use a selector that will select all the rows and take the length.

var rowCount = $('#myTable tr').length;

Note: this approach also counts all trs of every nested table!

I prefer to use BIGINT, and store the values in by multiply with 100, so that it will become integer.

For e.g., to represent a currency value of 93.49, the value shall be stored as 9349, while displaying the value we can divide by 100 and display. This will occupy less storage space.

Caution:
Mostly we don't perform currency * currency multiplication, in case if we are doing it then divide the result with 100 and store, so that it returns to proper precision.

And this works for me:

$(function () {
    $('#datetimepicker5').datetimepicker({
        format: 'HH:mm'
    });
});

Go to src folder of the project and copy all the code from it to some temporary location and build the project. And now copy the actual code from temporary location to project src. And run the build again. Problem will be resolved.

Note: This is specific to eclipse.

By using map function you can do that. Please refer below code.

var userDetails = [{
  "_id":"5078c3a803ff4197dc81fbfb",
  "email":"[email protected]",
  "image":"some_image_url",
  "name":"Name 1"
},{
  "_id":"5078c3a803ff4197dc81fbfc",
  "email":"[email protected]",
  "image":"some_image_url",
  "name":"Name 2"
}];

var formattedUserDetails = userDetails.map(({ _id:id, email, image, name }) => ({
  id,
  email,
  image,
  name
}));
console.log(formattedUserDetails);

It seems to be a long-running framework process for debugging (to decrease load times?). I discovered that when you start your application twice from the debugger often the same vshost.exe process will be used. It just unloads all user-loaded DLLs first. This does odd things if you are fooling around with API hooks from managed processes.

easier answer - put the stuff in quotes in different cells and then concatenate them!

B1: rcrCheck.asp
C1: =D1&B1&E1
D1: "code in quotes" and "more code in quotes"  
E1: "

it comes out perfect (can't show you because I get a stupid dialog box about code)

easy peasy!!

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

Convert your number to a Numeric or Decimal.

Replace your query with the following.

Sql server

Select Convert(Numeric(38, 2), Minutes/60.0) from ....

MySql:

Select Convert(Minutes/60.0, Decimal(65, 2)) from ....

The Cast function is a wrapper for the Convert function. Couple that with SQL being an interpreted language and the result is that even though the two functions produce the same results, there is slightly more going on behind the scenes in the Cast function. Using the Convert function is a small saving, but small savings multiply. The parameters for Numeric and Decimal (38, 2) and (65, 2) represent the maximum precision level and decimal places to use.

// Excuse my beginner's english

There is msgHTML() method, which, also, call IsHTML().

Hrm... name IsHTML is confusing...

/**

 * @param bool $advanced Whether to use the advanced HTML to text converter
 * @return string $message
 */
public function msgHTML($message, $basedir = '', $advanced = false)

There are some nice answers on this question. I’ll try to add a more broad answer, namely about what these kinds of lines/headers/trailers are about in current practice. Not so much about the sign-off header in particular (it’s not the only one).

Headers or trailers (?1) like “sign-off” (?2) is, in current practice in projects like Git and Linux, effectively structured metadata for the commit. These are all appended to the end of the commit message, after the “free form” (unstructured) part of the body of the message. These are token–value (or key–value) pairs typically delimited by a colon and a space (:?).

Like I mentioned, “sign-off” is not the only trailer in current practice. See for example this commit, which has to do with “Dirty Cow”:

 mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
 This is an ancient bug that was actually attempted to be fixed once
 (badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
 get_user_pages() race for write access") but that was then undone due to
 problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").

 In the meantime, the s390 situation has long been fixed, and we can now
 fix it by checking the pte_dirty() bit properly (and do it better).  The
 s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
 software dirty bits") which made it into v3.9.  Earlier kernels will
 have to look at the page state itself.

 Also, the VM has become more scalable, and what used a purely
 theoretical race back then has become easier to trigger.

 To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
 we already did a COW" rather than play racy games with FOLL_WRITE that
 is very fundamental, and then use the pte dirty flag to validate that
 the FOLL_COW flag is still valid.

In addition to the “sign-off” trailer in the above, there is:

• “Cc” (was notified about the patch)
• “Acked-by” (acknowledged by the owner of the code, “looks good to me”)
• “Reviewed-by” (reviewed)
• “Reported-and-tested-by” (reported and tested the issue (I assume))

Other projects, like for example Gerrit, have their own headers and associated meaning for them.

Moral of the story

It is my impression that, although the initial motivation for this particular metadata was some legal issues (judging by the other answers), the practice of such metadata has progressed beyond just dealing with the case of forming a chain of authorship.

[?1]: man git-interpret-trailers
[?2]: These are also sometimes called “s-o-b” (initials), it seems.

I just successfully installed a package for excel. After installing the python 3.6, you have to download the desired package, then install. For eg,

1. python.exe -m pip download openpyxl==2.1.4

2. python.exe -m pip install openpyxl==2.1.4

// service: (nothing special here)

myApp.service('myService', function() {
  return { someVariable:'abc123' };
});

// ctrl:

myApp.controller('MyCtrl', function($scope, myService) {

  $scope.someVariable = myService.someVariable;

  // watch the service and update this ctrl...
  $scope.$watch(function(){
    return myService.someVariable;
  }, function(newValue){
    $scope.someVariable = newValue;
  });
});

As already mentioned, compiling the app in x64 gives you far more available memory.

But in the case one must build an app in x86, there is a way to raise the memory limit from 1,2GB to 4GB (which is the actual limit for 32 bit processes):

In the VC/bin folder of the Visual Studio installation directory, there must be an editbin.exe file. So in my default installation I find it under

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\editbin.exe

In order to make the program work, maybe you must execute vcvars32.bat in the same directory first. Then a

editbin /LARGEADDRESSAWARE <your compiled exe file>

is enough to let your program use 4GB RAM. <your compiled exe file> is the exe, which VS generated while compiling your project.

If you want to automate this behavior every time you compile your project, use the following Post-Build event for the executed project:

if exist "$(DevEnvDir)..\tools\vsvars32.bat" (
   call "$(DevEnvDir)..\tools\vsvars32.bat"
   editbin /largeaddressaware "$(TargetPath)"
)

Sidenote: The same can be done with the devenv.exe to let Visual Studio also use 4GB RAM instead of 1.2GB (but first backup the old devenv.exe).

You need to use the openssl pkcs12 -export -chain -in server.crt -CAfile ...

See https://www.openssl.org/docs/apps/pkcs12.html

It can be accomplished with a simple one-liner.

Having this array:

$arr = array('nice_item', 'remove_me', 'another_liked_item', 'remove_me_also');

You can do:

$arr = array_diff($arr, array('remove_me', 'remove_me_also'));

And the value of $arr will be:

array('nice_item', 'another_liked_item')

You should add mode history to your router like the below

export default new Router({
  mode: 'history',
  routes: [
    {
     ...
    }
  ]
}) 

It really all comes down to how you want to handle output that the command might return and whether you want your PHP script to wait for the callee program to finish or not.

• exec executes a command and passes output to the caller (or returns it in an optional variable).

• passthru is similar to the exec() function in that it executes a command . This function should be used in place of exec() or system() when the output from the Unix command is binary data which needs to be passed directly back to the browser.

• system executes an external program and displays the output, but only the last line.

If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

This very second in time

ps -U $(whoami) -eom pid,pmem,pcpu,comm | head -n4

Continuously updating

watch -n 1 'ps -U $(whoami) -eom pid,pmem,pcpu,comm | head -n4'

I also added a few goodies here you might appreciate (or you might ignore)

-n 1 watch and update every second

-U $(whoami) To show only your processes. $(some command) evaluates now

| head -n4 To only show the header and 3 processes at a time bc often you just need high usage line items

${1-4} says my first argument $1 I want to default to 4, unless I provide it

If you are using a mac you may need to install watch first brew install watch

Alternatively you might use a function

psm(){
    watch -n 1 "ps -eom pid,pmem,pcpu,comm | head -n ${1-4}"
    # EXAMPLES: 
    # psm 
    # psm 10
}

This will depend on the device you're using. If you're using a pdf device, you can do this:

pdf( "mygraph.pdf", width = 11, height = 8 )
plot( x, y )

You can then divide up the space in the pdf using the mfrow parameter like this:

par( mfrow = c(2,2) )

That makes a pdf with four panels available for plotting. Unfortunately, some of the devices take different units than others. For example, I think that X11 uses pixels, while I'm certain that pdf uses inches. If you'd just like to create several devices and plot different things to them, you can use dev.new(), dev.list(), and dev.next().

Other devices that might be useful include:

• X11
• postscript
• BMP, JPEG, PNG and TIFF
• quartz (OSX only)

There's a list of all of the devices here.

For future reference, one can use this code

ES6:

_clone: function(obj){
    let newObj = {};
    for(let i in obj){
        if(typeof(obj[i]) === 'object' && Object.keys(obj[i]).length){
            newObj[i] = clone(obj[i]);
        } else{
            newObj[i] = obj[i];
        }
    }
    return Object.assign({},newObj);
}

function clone(obj){
let newObj = {};
for(let i in obj){
    if(typeof(obj[i]) === 'object' && Object.keys(obj[i]).length){

    } else{
        newObj[i] = obj[i];
    }
}
return Object.assign({},newObj);

}

E.g

var obj ={a:{b:1,c:3},d:4,e:{f:6}}
var xc = clone(obj);
console.log(obj); //{a:{b:1,c:3},d:4,e:{f:6}}
console.log(xc); //{a:{b:1,c:3},d:4,e:{f:6}}

xc.a.b = 90;
console.log(obj); //{a:{b:1,c:3},d:4,e:{f:6}}
console.log(xc); //{a:{b:90,c:3},d:4,e:{f:6}}
