Go to build path... delete existing maven library u added... click add library ... click maven managed dependencies... then click maven project settings... check resolve maven dependencies check box..it'll download all maven dependencies

You use pluginManagement in a parent pom to configure it in case any child pom wants to use it, but not every child plugin wants to use it. An example can be that your super pom defines some options for the maven Javadoc plugin.

Not each child pom might want to use Javadoc, so you define those defaults in a pluginManagement section. The child pom that wants to use the Javadoc plugin, just defines a plugin section and will inherit the configuration from the pluginManagement definition in the parent pom.

In your eclipse, go to Windows -> Preferences -> Maven Tick the option "Download repository index updates on startup". You may want to restart the eclipse.

Also go to Windows -> Show view -> Other -> Maven -> Maven repositories

On Maven repositories panel, Expand Global repositories then Right click on Central repositories and check "Full index enabled" option and then click on "Rebuild index".

You can use the function ginv() (Moore-Penrose generalized inverse) in the MASS package

Building upon suryaPavan's answer this slight modification can cleanup the empty object after removing the invidival emptys inside the object or array. this ensures that you don't have an empty array or object hanging around.

function removeNullsInObject(obj) {
            if( typeof obj === 'string' || obj === "" ){
                return;
            }
            $.each(obj, function(key, value){
                if (value === "" || value === null){
                    delete obj[key];
                } else if ($.isArray(value)) {
                    if( value.length === 0 ){
                        delete obj[key];
                        return;
                    }
                    $.each(value, function (k,v) {
                        removeNullsInObject(v);
                    });
                    if( value.length === 0 ){
                        delete obj[key];
                    }
                } else if (typeof value === 'object') {
                    if( Object.keys(value).length === 0 ){
                        delete obj[key];
                        return;
                    }
                    removeNullsInObject(value);
                    if( Object.keys(value).length === 0 ){
                        delete obj[key];

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.

JDK vs OpenJDK

First, make sure you have Tkinter module installed.

sudo apt-get install python-tk

In python 2 the package name is Tkinter not tkinter.

from Tkinter import *

In my case, I had to select the "src/main/java" and select the "Run As" menu Just like this, so that "Spring Boot App" would be displayed as here.

You can call Function onChange()

  <input type="radio" name="radioName" value="1" onchange="radio_changed($(this).val())" /> 1 <br />
  <input type="radio" name="radioName" value="2" onchange="radio_changed($(this).val())"  /> 2 <br />
  <input type="radio" name="radioName" value="3"  onchange="radio_changed($(this).val())" /> 3 <br />

<script>
function radio_changed(val){
    alert(val);
}
</script>

I have a Joomla Module that displays stuff... and I want to be able to share that stuff on facebook and not the Page's Title Meta Description... so my workaround is to have a secret .php file on the server that gets executed when it detects the FB's

$_SERVER['HTTP_USER_AGENT']

if($_SERVER['HTTP_USER_AGENT'] != 'facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)') {
    echo 'Direct Access';
} else {
    echo 'FB Accessed';
}

and pass variables with the URL that formats that particular page with the title and meta desciption of the item I want to share from my joomla module...

a name="fb_share" share_url="MYURL/sharer.php?title=TITLE&desc=DESC"

hope this helps...

On rails 4.2.2, go to application.rb and use config.time_zone='city' (e.g.:'London' or 'Bucharest' or 'Amsterdam' and so on).

It should work just fine. It worked for me.

"[a-zA-Z]" matches only one character. To match multiple characters, use "[a-zA-Z]+".

Since a dot is a joker for any character, you have to mask it: "abc\." To make the dot optional, you need a question mark: "abc\.?"

If you write the Pattern as literal constant in your code, you have to mask the backslash:

System.out.println ("abc".matches ("abc\\.?"));
System.out.println ("abc.".matches ("abc\\.?"));
System.out.println ("abc..".matches ("abc\\.?"));

Combining both patterns:

System.out.println ("abc.".matches ("[a-zA-Z]+\\.?"));

Instead of a-zA-Z, \w is often more appropriate, since it captures foreign characters like äöüßø and so on:

System.out.println ("abc.".matches ("\\w+\\.?"));   

Update: March 2020

According to Android developer official documentation, AsyncTask is now deprecated.

It's recommended to use kotlin corourines instead. Simply, it allows you to write asynchronous tasks in a sequential style.

If it's a sorted array you could use a Binary search algorithm (O(log n)). For example, extending the Array-class with this functionality:

class Array
  def b_search(e, l = 0, u = length - 1)
    return if lower_index > upper_index

    midpoint_index = (lower_index + upper_index) / 2
    return midpoint_index if self[midpoint_index] == value

    if value < self[midpoint_index]
      b_search(value, lower_index, upper_index - 1)
    else
      b_search(value, lower_index + 1, upper_index)
    end
  end
end

private void btnchangerate_Click(object sender, EventArgs e)
    {
        this.Hide();  //current form will hide
        Form1 fm = new Form1(); //another form will open
        fm.Show();


    }

on click btn current form will hide and new form will open

Note: This is a proper answer for a legacy version of AngularJS. See this question for updated versions.

$scope.$on('$routeChangeStart', function($event, next, current) { 
   // ... you could trigger something here ...
 });

The following events are also available (their callback functions take different arguments):

• $routeChangeSuccess
• $routeChangeError
• $routeUpdate - if reloadOnSearch property has been set to false

See the $route docs.

There are two other undocumented events:

• $locationChangeStart
• $locationChangeSuccess

See What's the difference between $locationChangeSuccess and $locationChangeStart?

Maybe you can think about removing the attribute to a function. I mean something like this:

var obj = {_x000D_
  key1: "it ",_x000D_
  key2: function() {_x000D_
    return this.key1 + " works!";_x000D_
  }_x000D_
};_x000D_
_x000D_
alert(obj.key2());

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.

SELECT ...
SELECT SLEEP(5);
SELECT ...

But what are you using this for? Are you trying to circumvent/reinvent mutexes or transactions?

I was using Android Pie and nothing seemed to worked so I played around with app:tabTextAppearance attribute. I know its not the perfect answer but might help someone.

<android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed"
        app:tabTextAppearance="@style/TextAppearance.AppCompat.Caption" />

Disable horizontal scrolling by overriding contentOffset property in subclass.

override var contentOffset: CGPoint {
  get {
    return super.contentOffset
  }
  set {
    super.contentOffset = CGPoint(x: 0, y: newValue.y)
  }
}

You are allocating your string on the stack, and then returning a pointer to it. When your function returns, any stack allocations become invalid; the pointer now points to a region on the stack that is likely to be overwritten the next time a function is called.

In order to do what you're trying to do, you need to do one of the following:

1. Allocate memory on the heap using malloc or similar, then return that pointer. The caller will then need to call free when it is done with the memory.
2. Allocate the string on the stack in the calling function (the one that will be using the string), and pass a pointer in to the function to put the string into. During the entire call to the calling function, data on its stack is valid; its only once you return that stack allocated space becomes used by something else.

If your SQL database allows Null values for that field try using int? value like that :

if (this.txtboxname.Text == "" || this.txtboxname.text == null)
     value = null;
else
     value = Convert.ToInt32(this.txtboxname.Text);

Take care that Convert.ToInt32 of a null value returns 0 !

Convert.ToInt32(null) returns 0

If you want to execute a function when something is done. One of a good solution is to listen to events. For example, I'll implement a Dispatcher, a DispatcherEvent class with ES6,then:

let Notification = new Dispatcher()
Notification.on('Load data success', loadSuccessCallback)

const loadSuccessCallback = (data) =>{
   ...
}
//trigger a event whenever you got data by
Notification.dispatch('Load data success')

Dispatcher:

class Dispatcher{
  constructor(){
    this.events = {}
  }

  dispatch(eventName, data){
    const event = this.events[eventName]
    if(event){
      event.fire(data)
    }
  }

  //start listen event
  on(eventName, callback){
    let event = this.events[eventName]
    if(!event){
      event = new DispatcherEvent(eventName)
      this.events[eventName] = event
    }
    event.registerCallback(callback)
  }

  //stop listen event
  off(eventName, callback){
    const event = this.events[eventName]
    if(event){
      delete this.events[eventName]
    }
  }
}

DispatcherEvent:

class DispatcherEvent{
  constructor(eventName){
    this.eventName = eventName
    this.callbacks = []
  }

  registerCallback(callback){
    this.callbacks.push(callback)
  }

  fire(data){
    this.callbacks.forEach((callback=>{
      callback(data)
    }))
  }
}

Happy coding!

p/s: My code is missing handle some error exceptions

No, there is not.

As other people have shown, there are ways to simulate Ruby's behavior. But it is possible to have a type that implements IEnumerable that does not expose an index.

I would try setting it to max-width:50px;

You can use:

git config --list

or look at your ~/.gitconfig file. The local configuration will be in your repository's .git/config file.

Use:

git config --list --show-origin

to see where that setting is defined (global, user, repo, etc...)

There are several ways.

1. awk has a system() function that will run a shell command:

   system("cmd")

2. You can print to a pipe:

   print "blah" | "cmd"

3. You can have awk construct commands, and pipe all the output to the shell:

   awk 'some script' | sh

Don't use IDs at all if you don't need to, instead wrap the input in a label like this:

<label>
   My Label
   <input type="text"/>
</label>

Then you won't need to worry about unique IDs.

This regex is very short and sweet for working.

/^([+]\d{2})?\d{10}$/

Ex: +910123456789 or 0123456789

-> /^ and $/ is for starting and ending
-> The ? mark is used for conditional formatting where before question mark is available or not it will work
-> ([+]\d{2}) this indicates that the + sign with two digits '\d{2}' here you can place digit as per country
-> after the ? mark '\d{10}' this says that the digits must be 10 of length change as per your country mobile number length

This is how this regex for mobile number is working.
+ sign is used for world wide matching of number.

if you want to add the space between than you can use the

[ ]

here the square bracket represents the character sequence and a space is character for searching in regex.
for the space separated digit you can use this regex

/^([+]\d{2}[ ])?\d{10}$/

Ex: +91 0123456789

Thanks ask any question if you have.

What does copying an object mean? There are a few ways you can copy objects--let's talk about the 2 kinds you're most likely referring to--deep copy and shallow copy.

Since we're in an object-oriented language (or at least are assuming so), let's say you have a piece of memory allocated. Since it's an OO-language, we can easily refer to chunks of memory we allocate because they are usually primitive variables (ints, chars, bytes) or classes we defined that are made of our own types and primitives. So let's say we have a class of Car as follows:

class Car //A very simple class just to demonstrate what these definitions mean.
//It's pseudocode C++/Javaish, I assume strings do not need to be allocated.
{
private String sPrintColor;
private String sModel;
private String sMake;

public changePaint(String newColor)
{
   this.sPrintColor = newColor;
}

public Car(String model, String make, String color) //Constructor
{
   this.sPrintColor = color;
   this.sModel = model;
   this.sMake = make;
}

public ~Car() //Destructor
{
//Because we did not create any custom types, we aren't adding more code.
//Anytime your object goes out of scope / program collects garbage / etc. this guy gets called + all other related destructors.
//Since we did not use anything but strings, we have nothing additional to handle.
//The assumption is being made that the 3 strings will be handled by string's destructor and that it is being called automatically--if this were not the case you would need to do it here.
}

public Car(const Car &other) // Copy Constructor
{
   this.sPrintColor = other.sPrintColor;
   this.sModel = other.sModel;
   this.sMake = other.sMake;
}
public Car &operator =(const Car &other) // Assignment Operator
{
   if(this != &other)
   {
      this.sPrintColor = other.sPrintColor;
      this.sModel = other.sModel;
      this.sMake = other.sMake;
   }
   return *this;
}

}

A deep copy is if we declare an object and then create a completely separate copy of the object...we end up with 2 objects in 2 completely sets of memory.

Car car1 = new Car("mustang", "ford", "red");
Car car2 = car1; //Call the copy constructor
car2.changePaint("green");
//car2 is now green but car1 is still red.

Now let's do something strange. Let's say car2 is either programmed wrong or purposely meant to share the actual memory that car1 is made of. (It's usually a mistake to do this and in classes is usually the blanket it's discussed under.) Pretend that anytime you ask about car2, you're really resolving a pointer to car1's memory space...that's more or less what a shallow copy is.

//Shallow copy example
//Assume we're in C++ because it's standard behavior is to shallow copy objects if you do not have a constructor written for an operation.
//Now let's assume I do not have any code for the assignment or copy operations like I do above...with those now gone, C++ will use the default.

 Car car1 = new Car("ford", "mustang", "red"); 
 Car car2 = car1; 
 car2.changePaint("green");//car1 is also now green 
 delete car2;/*I get rid of my car which is also really your car...I told C++ to resolve 
 the address of where car2 exists and delete the memory...which is also
 the memory associated with your car.*/
 car1.changePaint("red");/*program will likely crash because this area is
 no longer allocated to the program.*/

So regardless of what language you're writing in, be very careful about what you mean when it comes to copying objects because most of the time you want a deep copy.

What are the copy constructor and the copy assignment operator? I have already used them above. The copy constructor is called when you type code such as Car car2 = car1; Essentially if you declare a variable and assign it in one line, that's when the copy constructor is called. The assignment operator is what happens when you use an equal sign--car2 = car1;. Notice car2 isn't declared in the same statement. The two chunks of code you write for these operations are likely very similar. In fact the typical design pattern has another function you call to set everything once you're satisfied the initial copy/assignment is legitimate--if you look at the longhand code I wrote, the functions are nearly identical.

When do I need to declare them myself? If you are not writing code that is to be shared or for production in some manner, you really only need to declare them when you need them. You do need to be aware of what your program language does if you choose to use it 'by accident' and didn't make one--i.e. you get the compiler default. I rarely use copy constructors for instance, but assignment operator overrides are very common. Did you know you can override what addition, subtraction, etc. mean as well?

How can I prevent my objects from being copied? Override all of the ways you're allowed to allocate memory for your object with a private function is a reasonable start. If you really don't want people copying them, you could make it public and alert the programmer by throwing an exception and also not copying the object.

1. Press the Apps menu button on your Android mobile phone device. It will display icons of all the apps installed on your mobile phone device. Press Settings.

2. Press Apps. (Pressing on Apps button will list down all the apps installed on your mobile phone.

3. Browse the Apps list and press on the app called "Launcher 3". (Launcher 3 is an app and it will be listed in the App list whenever you access Settings > Apps in your android phone).

4. Pressing on the "Launcher 3" app will open the "App info screen" which will show some details pertaining to that app. On this App info screen, you will find buttons like "Force Stop", "Uninstall", "Clear Data" and "Clear Cache" etc.

5. In Android Marshmallow (i.e. Android 6.0) choose Settings > Apps > Launcher3 > STORAGE. Press "Clear Cache". If this fails, press "Clear data". This will eventually restore functionality, but all custom shortcuts will be lost.

Restart the phone and its done. All the home screens along with app shortcuts will appear again and your mobile phone is at your service again.

I hope it explains well on how to solve the launcher problem in Android. Worked for me.

A possible solution:

dir|find "bytes free"

a more "advanced solution", for Windows Xp and beyond:

wmic /node:"%COMPUTERNAME%" LogicalDisk Where DriveType="3" Get DeviceID,FreeSpace|find /I "c:"

The Windows Management Instrumentation Command-line (WMIC) tool (Wmic.exe) can gather vast amounts of information about about a Windows Server 2003 as well as Windows XP or Vista. The tool accesses the underlying hardware by using Windows Management Instrumentation (WMI). Not for Windows 2000.

As noted by Alexander Stohr in the comments:

• WMIC can see policy based restrictions as well. (even if 'dir' will still do the job),
• 'dir' is locale dependent.

Use:

string str = "Hello";
char[] characters = str.ToCharArray();

If you have a single character string, You can also try

string str = "A";
char character = char.Parse(str);    

//OR 
string str = "A";
char character = str.ToCharArray()[0];

See this brilliant blog post about animating values in objects.. you can then use the values to animate whatever you like, 100% simultaneously!

http://www.josscrowcroft.com/2011/code/jquery-animate-increment-decrement-numeric-text-elements-value/

I've used it like this to slide in/out:

        slide : function(id, prop, from, to) {
            if (from < to) {
                // Sliding out
                var fromvals = { add: from, subtract: 0 };
                var tovals = { add: to, subtract: 0 };
            } else {
                // Sliding back in
                var fromvals = { add: from, subtract: to };
                var tovals = { add: from, subtract: from };
            }

            $(fromvals).animate(tovals, {
                duration: 200,
                easing: 'swing', // can be anything
                step: function () { // called on every step
                    // Slide using the entire -ms-grid-columns setting
                    $(id).css(prop, (this.add - this.subtract) + 'px 1.5fr 0.3fr 8fr 3fr 5fr 0.5fr');
                }
            });
        }

I can do it in O(n). Let me know when you want the answer. Note it involves simply traversing the array once with no sorting, etc... I should mention too that it exploits commutativity of addition and doesn't use hashes but wastes memory.

using System; using System.Collections.Generic;

/* An O(n) approach exists by using a lookup table. The approach is to store the value in a "bin" that can easily be looked up(e.g., O(1)) if it is a candidate for an appropriate sum.

e.g.,

for each a[k] in the array we simply put the it in another array at the location x - a[k].

Suppose we have [0, 1, 5, 3, 6, 9, 8, 7] and x = 9

We create a new array,

indexes value

9 - 0 = 9     0
9 - 1 = 8     1
9 - 5 = 4     5
9 - 3 = 6     3
9 - 6 = 3     6
9 - 9 = 0     9
9 - 8 = 1     8
9 - 7 = 2     7

THEN the only values that matter are the ones who have an index into the new table.

So, say when we reach 9 or equal we see if our new array has the index 9 - 9 = 0. Since it does we know that all the values it contains will add to 9. (note in this cause it's obvious there is only 1 possible one but it might have multiple index values in it which we need to store).

So effectively what we end up doing is only having to move through the array once. Because addition is commutative we will end up with all the possible results.

For example, when we get to 6 we get the index into our new table as 9 - 6 = 3. Since the table contains that index value we know the values.

This is essentially trading off speed for memory. */

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

Put the code that you want executed after the delay within the setTimeout callback:

console.log('Welcome to My Console,');
setTimeout(function() {
    console.log('Blah blah blah blah extra-blah');
}, 3000);

Deprecated solution

valueLink/checkedLink are deprecated from core React, because it is confusing some users. This answer won't work if you use a recent version of React. But if you like it, you can easily emulate it by creating your own Input component

Old answer content:

What you want to achieve can be much more easily achieved using the 2-way data binding helpers of React.

var Hello = React.createClass({
    mixins: [React.addons.LinkedStateMixin],
    getInitialState: function() {
        return {input1: 0, input2: 0};
    },

    render: function() {
        var total = this.state.input1 + this.state.input2;
        return (
            <div>{total}<br/>
                <input type="text" valueLink={this.linkState('input1')} />;
                <input type="text" valueLink={this.linkState('input2')} />;
            </div>
        );
    }

});

React.renderComponent(<Hello />, document.getElementById('content'));

Easy right?

http://facebook.github.io/react/docs/two-way-binding-helpers.html

You can even implement your own mixin

When you use android:background, you are replacing much of the styling and look and feel of a button with a blank color.

Update: As of the version 23.0.0 release of AppCompat, there is a new Widget.AppCompat.Button.Colored style which uses your theme's colorButtonNormal for the disabled color and colorAccent for the enabled color.

This allows you apply it to your button directly via

<Button
  ...
  style="@style/Widget.AppCompat.Button.Colored" />

If you need a custom colorButtonNormal or colorAccent, you can use a ThemeOverlay as explained in this pro-tip and android:theme on the button.

Previous Answer

You can use a drawable in your v21 directory for your background such as:

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
        android:color="?attr/colorControlHighlight">
    <item android:drawable="?attr/colorPrimary"/>
</ripple>

This will ensure your background color is ?attr/colorPrimary and has the default ripple animation using the default ?attr/colorControlHighlight (which you can also set in your theme if you'd like).

Note: you'll have to create a custom selector for less than v21:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/primaryPressed" android:state_pressed="true"/>
    <item android:drawable="@color/primaryFocused" android:state_focused="true"/>
    <item android:drawable="@color/primary"/>
</selector>

Assuming you have some colors you'd like for the default, pressed, and focused state. Personally, I took a screenshot of a ripple midway through being selected and pulled the primary/focused state out of that.

You could also check out the "Data Scripter Add-In" for SQL Server Management Studio 2008 from:

http://www.mssql-vehicle-data.com/SSMS

Their features list:

• It was developed on SSMS 2008 and is not supported on the 2005 version at this time (soon!)

• Export data quickly to T-SQL for MSSQL and MySQL syntax

• CSV, TXT, XML are also supported! Harness the full potential, power, and speed that SQL has to offer.

• Don't wait for Access or Excel to do scripting work for you that could take several minutes to do -- let SQL Server do it for you and take all the guess work out of exporting your data!

• Customize your data output for rapid backups, DDL manipulation, and more...

• Change table names and database schemas to your needs, quickly and efficiently

• Export column names or simply generate data without the names.

• You can chose individual columns to script.

• You can chose sub-sets of data (WHERE clause).

• You can chose ordering of data (ORDER BY clause).

• Great backup utility for those grungy database debugging operations that require data manipulation. Don't lose data while experimenting. Manipulate data on the fly!

Make a temporary table (tempP) from a subquery

UPDATE pers P 
SET P.gehalt = P.gehalt * 1.05 
WHERE P.persID IN (
    SELECT tempP.tempId
    FROM (
        SELECT persID as tempId
        FROM pers P
        WHERE
            P.chefID IS NOT NULL OR gehalt < 
                (SELECT (
                    SELECT MAX(gehalt * 1.05) 
                    FROM pers MA 
                    WHERE MA.chefID = MA.chefID) 
                    AS _pers
                )
    ) AS tempP
)

I've introduced a separate name (alias) and give a new name to 'persID' column for temporary table

Easiest way to install MSSQL 2012 MS SQL INSTALLATION

Here i am showing the easiest way to install ms sql 2012.

My opinion is the installation will be easier with windows 8.1 rather than windows 7.

This is my personnal opinion only.

We can install in windows 7 as well.

The steps to be followed:

Download any one of the link using the following URL

http://www.microsoft.com/en-us/download/details.aspx?id=43351

SQLEXPRWT_x86_ENU.exe or SQLEXPRWT_x64_ENU.exe

http://www.microsoft.com/en-us/download/details.aspx?id=42299

SQLEXPRWT_x86_ENU.exe or SQLEXPRWT_x64_ENU.exe

Right click on .exe file and run it

We should leave everything default while installing.

During installation, there will be 2 options:

1)If you are New user,then click on new sql-server stand alone application.

2)If you have already MS SQL application then you can upgrade by using the other option.

Then accept the Licence terms and click Next.

Now you will move on to Product Updates and press next then Setup support rules.

After this Feature selection.According to me we can check all the boxes except localdb.

Next it will take you to Instance Configuration where you should select Named Instance as

"SQLEXPRESS".

Then go to Server Configuration and press next.

Now Database engine configuration:

Authentication Mode:we can click on any one that is windows authentication mode or mixed.

Windows authentication mode (default for windows).

Mixed authentication mode:then should create username and password.

Then move on Error reporting,we can move further by clicking next to install process.

Finally we can see the Complete windows by showing the products added .

We can close and run the MSSQL server.

I hope it's useful.

Ramya

I got this error when I dynamically read data from a WebRequest and never closed the Response.

    protected System.IO.Stream GetStream(string url)
    {
        try
        {
            System.IO.Stream stream = null;
            var request = System.Net.WebRequest.Create(url);
            var response = request.GetResponse();

            if (response != null) {
                stream = response.GetResponseStream();

                // I never closed the response thus resulting in the error
                response.Close(); 
            }
            response = null;
            request = null;

            return stream;
        }
        catch (Exception) { }
        return null;
    }

The SetEnv.cmd script that the "SDK command prompt" shortcut runs checks for cl.exe in various places before setting up entries to add to PATH. So it fails to add anything if a native C compiler is not installed.

To fix that, apply the following patch to <SDK install dir>\Bin\SetEnv.cmd. This will also fix missing paths to other tools located in <SDK install dir>\Bin and subfolders. Of course, you can install the C compiler instead to work around this bug.

For these who don't get proper results other than mentioned languages, if you're using C# to print a text into console(terminal) window you should replace "\033" with "\x1b". In Visual Basic it would be Chrw(27).

You can use one of the moment plugin -> moment-range to deal with date range:

var startDate = new Date(2013, 1, 12)
  , endDate   = new Date(2013, 1, 15)
  , date  = new Date(2013, 2, 15)
  , range = moment().range(startDate, endDate);

range.contains(date); // false

If you connect a device while the app is building/archiving, your generic device will change to your connected device automatically, and when you are trying to upload to the app store you will have that weird crash.

This:

will change to this automatically:

So to answer your question, I don't know if your issue have been caused because you plugged your iOs device while archiving, but you will be able to reproduce that issue if you plug your iOS device while archiving your app. Hope this helps somebody

The simplest way to put this into perspective for memorization by behavior (in terms of PHP):

• bindParam: reference
• bindValue: variable

MainCode

Uri raw_uri=Uri.parse("android.resource://<package_name>/+R.raw.<video_file_name>);

myVideoView=(VideoView)findViewbyID(R.idV.Video_view);

myVideoView.setVideoURI(raw_uri);
myVideoView.setMediaController(new MediaController(this));
myVideoView.start();
myVideoView.requestFocus();

Use html-pdf

var fs = require('fs');
var pdf = require('html-pdf');
var html = fs.readFileSync('./test/businesscard.html', 'utf8');
var options = { format: 'Letter' };

pdf.create(html, options).toFile('./businesscard.pdf', function(err, res) {
  if (err) return console.log(err);
  console.log(res); // { filename: '/app/businesscard.pdf' } 
});

I had to do this to get it to work:

$pair = "$($user):$($pass)"
$encodedCredentials = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($Pair))
$headers = @{ Authorization = "Basic $encodedCredentials" }
Invoke-WebRequest -Uri $url -Method Get -Headers $headers -OutFile Config.html

This will take care of the empty td:

<td style="min-width: 20px;"></td>

It means the CPU attempted to execute an instruction it didn't understand. This could be caused by corruption I guess, or maybe it's been compiled for the wrong architecture (in which case I would have thought the O/S would refuse to run the executable). Not entirely sure what the root issue is.

The idea is, using the command cmd ipconfig /all and extract only the address mac.

Which his index $pmac+33.

And the size of mac is 17.

<?php
ob_start();
system('ipconfig /all');
$mycom=ob_get_contents();
ob_clean();
$findme = 'physique';
$pmac = strpos($mycom, $findme);
$mac=substr($mycom,($pmac+33),17);
echo $mac;
?>

I solved a similar error on Linux by setting PYTHONPATH to the site-packages location. This was after running python get-pip.py --prefix /home/chet/pip.

[chet@rhel1 ~]$ ~/pip/bin/pip -V
Traceback (most recent call last):
  File "/home/chet/pip/bin/pip", line 7, in <module>
    from pip import main
ImportError: No module named pip

[chet@rhel1 ~]$ export PYTHONPATH=/home/chet/pip/lib/python2.6/site-packages

[chet@rhel1 ~]$ ~/pip/bin/pip -V

It's worth noting that if you use the DownloadManager to kick off your download, be sure to save it to an external location e.g. setDestinationInExternalFilesDir(c, null, "<your name here>).apk";. The intent with a package-archive type doesn't appear to like the content: scheme used with downloads to an internal location, but does like file:. (Trying to wrap the internal path into a File object and then getting the path doesn't work either, even though it results in a file: url, as the app won't parse the apk; looks like it must be external.)

Example:

int uriIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI);
String downloadedPackageUriString = cursor.getString(uriIndex);
File mFile = new File(Uri.parse(downloadedPackageUriString).getPath());
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
        .setDataAndType(Uri.fromFile(mFile), "application/vnd.android.package-archive")
        .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
appContext.startActivity(promptInstall);

Once you run pip install jupyter. Make sure you restart the terminal so it would update environment and home variable. This worked for me

You simply use the destroy() method to delete the specified widgets like this:

lbl = tk.Label(....)

btn = tk.Button(....., command=lambda: lbl.destroy())

Using this you can completely destroy the specific widgets.

I picked node-sass implementer for libsass because it is based on node.js.

Installing node-sass

• (Prerequisite) If you don't have npm, install Node.js first.
• $ npm install -g node-sass installs node-sass globally -g.

This will hopefully install all you need, if not read libsass at the bottom.

How to use node-sass from Command line and npm scripts

General format:

$ node-sass [options] <input.scss> [output.css]
$ cat <input.scss> | node-sass > output.css

Examples:

1. $ node-sass my-styles.scss my-styles.css compiles a single file manually.
2. $ node-sass my-sass-folder/ -o my-css-folder/ compiles all the files in a folder manually.
3. $ node-sass -w sass/ -o css/ compiles all the files in a folder automatically whenever the source file(s) are modified. -w adds a watch for changes to the file(s).

More usefull options like 'compression' @ here. Command line is good for a quick solution, however, you can use task runners like Grunt.js or Gulp.js to automate the build process.

You can also add the above examples to npm scripts. To properly use npm scripts as an alternative to gulp read this comprehensive article @ css-tricks.com especially read about grouping tasks.

• If there is no package.json file in your project directory running $ npm init will create one. Use it with -y to skip the questions.
• Add "sass": "node-sass -w sass/ -o css/" to scripts in package.json file. It should look something like this:

"scripts": {
    "test" : "bla bla bla",
    "sass": "node-sass -w sass/ -o css/"
 }

• $ npm run sass will compile your files.

How to use with gulp

• $ npm install -g gulp installs Gulp globally.
• If there is no package.json file in your project directory running $ npm init will create one. Use it with -y to skip the questions.
• $ npm install --save-dev gulp installs Gulp locally. --save-dev adds gulp to devDependencies in package.json.
• $ npm install gulp-sass --save-dev installs gulp-sass locally.
• Setup gulp for your project by creating a gulpfile.js file in your project root folder with this content:

'use strict';
var gulp = require('gulp');

A basic example to transpile

Add this code to your gulpfile.js:

var gulp = require('gulp');
var sass = require('gulp-sass');
gulp.task('sass', function () {
  gulp.src('./sass/**/*.scss')
    .pipe(sass().on('error', sass.logError))
    .pipe(gulp.dest('./css'));
});

$ gulp sass runs the above task which compiles .scss file(s) in the sass folder and generates .css file(s) in the css folder.

To make life easier, let's add a watch so we don't have to compile it manually. Add this code to your gulpfile.js:

gulp.task('sass:watch', function () {
  gulp.watch('./sass/**/*.scss', ['sass']);
});

All is set now! Just run the watch task:

$ gulp sass:watch

How to use with Node.js

As the name of node-sass implies, you can write your own node.js scripts for transpiling. If you are curious, check out node-sass project page.

What about libsass?

Libsass is a library that needs to be built by an implementer such as sassC or in our case node-sass. Node-sass contains a built version of libsass which it uses by default. If the build file doesn't work on your machine, it tries to build libsass for your machine. This process requires Python 2.7.x (3.x doesn't work as of today). In addition:

LibSass requires GCC 4.6+ or Clang/LLVM. If your OS is older, this version may not compile. On Windows, you need MinGW with GCC 4.6+ or VS 2013 Update 4+. It is also possible to build LibSass with Clang/LLVM on Windows.

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

<?php echo exec('whoami'); ?>

I think it may be the sudo has no access to get ORACLE_HOME.You can do like this.

sudo visudo

modify the text add

Defaults env_keep += "ORACLE_HOME"

then

sudo python setup.py build install

It seems that the compiler is better in optimizing a switch-statement than an if-statement.

The compiler doesn't know if the order of evaluating the if-statements is important to you, and can't perform any optimizations there. You could be calling methods in the if-statements, influencing variables. With the switch-statement it knows that all clauses can be evaluated at the same time and can put them in whatever order is most efficient.

Here's a small comparison:
http://www.blackwasp.co.uk/SpeedTestIfElseSwitch.aspx

After insuring that the string "strOutput" has a correct XML structure, you can do this:

Matcher junkMatcher = (Pattern.compile("^([\\W]+)<")).matcher(strOutput);
strOutput = junkMatcher.replaceFirst("<");

That is nice question :)

When you have situation with 1 cell (A1), it is important to identify if second declared cell is not empty (sh.Range("A1").End(xlDown)). If it is true it means your range got out of control :) Look at code below:

Dim sh As Worksheet
Set sh = ThisWorkbook.Sheets("Arkusz1")

Dim k As Long

If IsEmpty(sh.Range("A1").End(xlDown)) = True Then
    k = 1

Else
    k = sh.Range("A1", sh.Range("A1").End(xlDown)).Rows.Count

End If

Include from the most specific to the least specific, starting with the corresponding .hpp for the .cpp, if one such exists. That way, any hidden dependencies in header files that are not self-sufficient will be revealed.

This is complicated by the use of pre-compiled headers. One way around this is, without making your project compiler-specific, is to use one of the project headers as the precompiled header include file.

On any Windows Version delete the following folder:

%APPDATA%\Subversion\auth

(You can copy&paste this to RUN/Explorer, and it will resolve the App-Data-Folder for you.)

On Linux and OSX it is located in

~/.subversion/auth

$SQL_Part=$SQL_Part+$cat[$i+1]+")"

$SQL="SELECT * FROM products WHERE catid IN "+$SQL_Part;

It's more generic and will fit for any array!!

Just had to fix this myself. The above answers don't seem to take into account the $mail->SMTPDebug = 0; option. It may not have been available when the question was first asked.

If you got your code from the PHPMail site, the default will be $mail->SMTPDebug = 2; // enables SMTP debug information (for testing)

https://github.com/Synchro/PHPMailer/blob/master/examples/test_smtp_gmail_advanced.php

Set the value to 0 to suppress the errors and edit the 'catch' part of your code as explained above.

If you want to convert from char to int, why not think about unicode number?

SELECT UNICODE(';') -- 59

This way you can convert any char to int without any error. Cheers.

You can archive it with a Service and Alarm Manager, but be careful with this, because if you setup a high priority you gonna drain the battery of the phone, in other hand, you really need notify the location every minute? This is because the only way to see a considerably change of the user location, it's traveling in a car or train. I only ask, because that gonna depend of you app and the requirement of the tracking.

import csv
dic = {firstcol,secondcol} #dictionary
csv = open('result.csv', "w") 
for key in dic.keys():
    row ="\n"+ str(key) + "," + str(dic[key]) 
    csv.write(row)

Here is an example

#!/bin/bash

default='default_value'
value=${1:-$default}

echo "value: [$value]"

save this as script.sh and make it executable. run it without params

./script.sh
> value: [default_value]

run it with param

./script.sh my_value
> value: [my_value]

it's simple, all the problems can be solved like this,

1) have escape always take you out of fullscreen mode (this doesn't apply to manually entering fullscreen through f11)

2) temporarily display a small banner saying fullscreen video mode is entered (by the browser)

3) block fullscreen action by default, just like has been done for pop-ups and local database in html5 and location api and etc, etc.

i don't see any problems with this design. anyone think i missed anything?

This works for all types.

List<object> objects = new List<object>();
List<string> strings = objects.Select(s => (string)s).ToList();

You can use below command

alter database Testing modify name=LearningSQL;

Old Database Name = Testing, New Database Name = LearningSQL

keytool comes with the JDK installation (in the bin folder):

keytool -importcert -file "your.cer" -keystore your.jks -alias "<anything>"

This will create a new keystore and add just your certificate to it.

So, you can't convert a certificate to a keystore: you add a certificate to a keystore.

if you try with lubridate:

library(lubridate)
lubridate::week(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))

[1] 11 11 12  1

The pattern is the same. Try isoweek

lubridate::isoweek(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))
[1] 11 12 12  1

A cleaner alternative would be the following:

Due to the fact that every async function is technically a promise

You can add catches to functions when calling them with await

async function a(){
    let error;

    // log the error on the parent
    await b().catch((err)=>console.log('b.failed'))

    // change an error variable
    await c().catch((err)=>{error=true; console.log(err)})

    // return whatever you want
    return error ? d() : null;
}
a().catch(()=>console.log('main program failed'))

No need for try catch, as all promises errors are handled, and you have no code errors, you can omit that in the parent!!

Lets say you are working with mongodb, if there is an error you might prefer to handle it in the function calling it than making wrappers, or using try catches.

If you want to randomly select more than one item from a list, or select an item from a set, I'd recommend using random.sample instead.

import random
group_of_items = {1, 2, 3, 4}               # a sequence or set will work here.
num_to_select = 2                           # set the number to select here.
list_of_random_items = random.sample(group_of_items, num_to_select)
first_random_item = list_of_random_items[0]
second_random_item = list_of_random_items[1] 

If you're only pulling a single item from a list though, choice is less clunky, as using sample would have the syntax random.sample(some_list, 1)[0] instead of random.choice(some_list).

Unfortunately though, choice only works for a single output from sequences (such as lists or tuples). Though random.choice(tuple(some_set)) may be an option for getting a single item from a set.

EDIT: Using Secrets

As many have pointed out, if you require more secure pseudorandom samples, you should use the secrets module:

import secrets                              # imports secure module.
secure_random = secrets.SystemRandom()      # creates a secure random object.
group_of_items = {1, 2, 3, 4}               # a sequence or set will work here.
num_to_select = 2                           # set the number to select here.
list_of_random_items = secure_random.sample(group_of_items, num_to_select)
first_random_item = list_of_random_items[0]
second_random_item = list_of_random_items[1]

EDIT: Pythonic One-Liner

If you want a more pythonic one-liner for selecting multiple items, you can use unpacking.

import random
first_random_item, second_random_item = random.sample(group_of_items, 2)

I had the same problem because of an table column which was defined as ENUM('x','y','z') and later on I was trying to save the value 'a' into this column, thus I got the mentioned error.

Solved by altering the table column definition and added value 'a' into the enum set.

Simple to me is like this:

$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"

"$Time,$Description"|Add-Content -Path $File # Keep no space between content variables

If you have a lot of columns, then create a variable like $NewRow like:

$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"
$NewRow = "$Time,$Description" # No space between variables, just use comma(,).

$NewRow | Add-Content -Path $File # Keep no space between content variables

Please note the difference between Set-Content (overwrites the existing contents) and Add-Content (appends to the existing contents) of the file.

To some extent Fortran has been designed keeping compiler optimization in mind. The language supports whole array operations where compilers can exploit parallelism (specially on multi-core processors). For example,

Dense matrix multiplication is simply:

matmul(a,b)

L2 norm of a vector x is:

sqrt(sum(x**2))

Moreover statements such as FORALL, PURE & ELEMENTAL procedures etc. further help to optimize code. Even pointers in Fortran arent as flexible as C because of this simple reason.

The upcoming Fortran standard (2008) has co-arrays which allows you to easily write parallel code. G95 (open source) and compilers from CRAY already support it.

So yes Fortran can be fast simply because compilers can optimize/parallelize it better than C/C++. But again like everything else in life there are good compilers and bad compilers.

for (i = 0; i < 16; i++)
{
    fscanf(myFile, "%d", &numberArray[i]);
}

This is attempting to read the whole string, "5623125698541159" into &numArray[0]. You need spaces between the numbers:

5 6 2 3 ...

you could use either PowerISO or WinRAR

If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE

Edit: On the model overview it's under Physical Schemata

Screenshot:

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

input -webkit-appearance: none; alone does not work.

Try adding -webkit-border-radius:0px; in addition.

I think you're missing your routes, you need to define at least one route for example '/' to index.

e.g.

app.get('/', function (req, res) {
  res.render('index', {});
});

Create the list (edited):

count_list = range(1, N+1)

Select random element:

import random
random.choice(count_list)

Ideally you would put that in a directive, but you can also just put it in the controller. http://jsfiddle.net/tnq86/15/

  angular.module('App', [])
    .controller('AppCtrl', function ($scope) {

      $scope.model = 0;

      $scope.initSlider = function () {
          $(function () {
            // wait till load event fires so all resources are available
              $scope.$slider = $('#slider').slider({
                  slide: $scope.onSlide
              });
          });

          $scope.onSlide = function (e, ui) {
             $scope.model = ui.value;
             $scope.$digest();
          };
      };

      $scope.initSlider();
  });

The directive approach:

HTML

<div slider></div>

JS

  angular.module('App', [])
    .directive('slider', function (DataModel) {
      return {
         restrict: 'A',
         scope: true,
         controller: function ($scope, $element, $attrs) {
            $scope.onSlide = function (e, ui) {
              $scope.model = ui.value;
              // or set it on the model
              // DataModel.model = ui.value;
              // add to angular digest cycle
              $scope.$digest();
            };
         },
         link: function (scope, el, attrs) {

            var options = {
              slide: scope.onSlide  
            };

            // set up slider on load
            angular.element(document).ready(function () {
              scope.$slider = $(el).slider(options);
            });
         }
      }
  });

I would also recommend checking out Angular Bootstrap's source code: https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js

You can also use a factory to create the directive. This gives you ultimate flexibility to integrate services around it and whatever dependencies you need.

request.getRequestDispatcher(“url”) means the dispatch is relative to the current HTTP request.Means this is for chaining two servlets with in the same web application Example

RequestDispatcher reqDispObj = request.getRequestDispatcher("/home.jsp");

getServletContext().getRequestDispatcher(“url”) means the dispatch is relative to the root of the ServletContext.Means this is for chaining two web applications with in the same server/two different servers

Example

RequestDispatcher reqDispObj = getServletContext().getRequestDispatcher("/ContextRoot/home.jsp");

I am not sure if there is a better way, but I can think of a hack to get it - you could Ajax post to the img URL, and parse the response to see if the image actually came back. If it came back as a 404 or something, then swap out the img. Though I expect this to be quite slow.

An alternative to the proposed:

QString qs;
std::string current_locale_text = qs.toLocal8Bit().constData();

could be:

QString qs;
std::string current_locale_text = qPrintable(qs);

See qPrintable documentation, a macro delivering a const char * from QtGlobal.

This look like a duplicate of JSTL conditional check.

The error is having the && outside the expression. Instead use

<c:if test="${ISAJAX == 0 && ISDATE == 0}">

You can simply use datetime diff and format for calculating difference.

<?php
$datetime1 = new DateTime('2009-10-11 12:12:00');
$datetime2 = new DateTime('2009-10-13 10:12:00');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%Y-%m-%d %H:%i:%s');
?>

For more information OF DATETIME format, refer: here
You can change the interval format in the way,you want.

Here is the working example

P.S. These features( diff() and format()) work with >=PHP 5.3.0 only

Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different.

Here are the commands to retrieve key value:

• if value is of type string -> GET <key>
• if value is of type hash -> HGETALL <key>
• if value is of type lists -> lrange <key> <start> <end>
• if value is of type sets -> smembers <key>
• if value is of type sorted sets -> ZRANGEBYSCORE <key> <min> <max>

Use the TYPE command to check the type of value a key is mapping to:

• type <key>

Here is a version that works well in September 2020 using fetch and https://worldtimeapi.org/api

fetch("https://worldtimeapi.org/api/ip")
  .then(response => response.json())
  .then(data => console.log(data.dst,data.datetime));

A relation schema is the logical definition of a table - it defines what the name of the table is, and what the name and type of each column is. It's like a plan or a blueprint. A database schema is the collection of relation schemas for a whole database.

A table is a structure with a bunch of rows (aka "tuples"), each of which has the attributes defined by the schema. Tables might also have indexes on them to aid in looking up values on certain columns.

A database is, formally, any collection of data. In this context, the database would be a collection of tables. A DBMS (Database Management System) is the software (like MySQL, SQL Server, Oracle, etc) that manages and runs a database.

To get the right ownership, you can set the group setuid bit on the directory with

chmod g+rwxs dirname

This will ensure that files created in the directory are owned by the group. You should then make sure everyone runs with umask 002 or 007 or something of that nature---this is why Debian and many other linux systems are configured with per-user groups by default.

I don't know of a way to force the permissions you want if the user's umask is too strong.

I often have this problem with sequences (as opposed to discrete values). If I have a sequence of ints, and I want to SUM them, when the list is empty I'll receive the error "InvalidOperationException: The null value cannot be assigned to a member with type System.Int32 which is a non-nullable value type.".

I find I can solve this by casting the sequence to a nullable type. SUM and the other aggregate operators don't throw this error if a sequence of nullable types is empty.

So for example something like this

MySum = MyTable.Where(x => x.SomeCondtion).Sum(x => x.AnIntegerValue);

becomes

MySum = MyTable.Where(x => x.SomeCondtion).Sum(x => (int?) x.AnIntegerValue);

The second one will return 0 when no rows match the where clause. (the first one throws an exception when no rows match).

Modified Johannes Wei's answer in the case 1new_month = 121. This works perfectly for me. The months could be positive or negative.

def addMonth(d,months=1):
    year, month, day = d.timetuple()[:3]
    new_month = month + months
    return datetime.date(year + ((new_month-1) / 12), (new_month-1) % 12 +1, day)

Did you try <br/>, <br><br/> or simply \n ? <br> should be supported according to this source, though.

Supported HTML tags

Here is the answer in Razor syntax

 <table border="1" cellpadding="5">
    <thead>
       <tr>
          @foreach (System.Data.DataColumn col in Model.Columns)
          {
             <th>@col.Caption</th>
          }
       </tr>
    </thead>
    <tbody>
    @foreach(System.Data.DataRow row in Model.Rows)
    {
       <tr>
          @foreach (var cell in row.ItemArray)
          {
             <td>@cell.ToString()</td>
          }
       </tr>
    }      
    </tbody>
</table>

Here's an example:

SELECT * FROM pubs WHERE name LIKE "%John's%"

Just use double quotes to enclose the single quote.

If you insist in using single quotes (and the need to escape the character):

SELECT * FROM pubs WHERE name LIKE '%John\'s%'

You can do this easily manually for each column like this:

df['A_perc'] = df['A']/df['sum']

If you want to do this in one step for all columns, you can use the div method (http://pandas.pydata.org/pandas-docs/stable/basics.html#matching-broadcasting-behavior):

ds.div(ds['sum'], axis=0)

And if you want this in one step added to the same dataframe:

>>> ds.join(ds.div(ds['sum'], axis=0), rsuffix='_perc')
          A         B         C         D       sum    A_perc    B_perc  \
1  0.151722  0.935917  1.033526  0.941962  3.063127  0.049532  0.305543

3  0.761368  0.484268  0.026837  1.276130  2.548603  0.298739  0.190013   

     C_perc    D_perc  sum_perc  
1  0.337409  0.307517         1  
2  0.305722  0.385701         1  
3  0.010530  0.500718         1  

Use:

File file = new File("Z:\\results\\results.txt");

You need to double the backslashes in Windows because the backslash character itself is an escape in Java literal strings.

For POSIX system such as Linux, just use the default file path without doubling the forward slash. this is because forward slash is not a escape character in Java.

File file = new File("/home/userName/Documents/results.txt");

Inside of a for-loop block, you can access some special variables including loop.index --but no loop.counter. From the official docs:

Variable    Description
loop.index  The current iteration of the loop. (1 indexed)
loop.index0 The current iteration of the loop. (0 indexed)
loop.revindex   The number of iterations from the end of the loop (1 indexed)
loop.revindex0  The number of iterations from the end of the loop (0 indexed)
loop.first  True if first iteration.
loop.last   True if last iteration.
loop.length The number of items in the sequence.
loop.cycle  A helper function to cycle between a list of sequences. See the explanation below.
loop.depth  Indicates how deep in a recursive loop the rendering currently is. Starts at level 1
loop.depth0 Indicates how deep in a recursive loop the rendering currently is. Starts at level 0
loop.previtem   The item from the previous iteration of the loop. Undefined during the first iteration.
loop.nextitem   The item from the following iteration of the loop. Undefined during the last iteration.
loop.changed(*val)  True if previously called with a different value (or not called at all).

chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]

This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:

data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]

Outputs:

[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]

I believe this will only appear when running the page locally in this particular case, i.e. you should not see this when loading the apge from a web server.

However if you have permission to do so, you could turn off the prompt for Internet Explorer by following Tools (menu) → Internet Options → Security (tab) → Custom Level (button) → and Disable Automatic prompting for ActiveX controls.

$_SERVER['REMOTE_ADDR']

• PHP_SELF Returns the filename of the current script with the path relative to the root

• SERVER_PROTOCOL Returns the name and revision of the page-requested protocol

• REQUEST_METHOD Returns the request method used to access the page

• DOCUMENT_ROOT Returns the root directory under which the current script is executing

In Visual Studio 2010, right click the project, choose Properties, click the configuring properties section on the left pane, then click Debugging, then on the right pane there is a box for command arguments.

In that enter the command line arguments. You are good to go. Now debug and see the result. If you are tired of changing in the properties then temporarily give the input directly in the program.

window.open('http://somelocation.com','mywin','width=500,height=500');

A one-L NUL, it ends a string.

A two-L NULL points to no thing.

And I will bet a golden bull

That there is no three-L NULLL.

How do you deal with NUL?

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

In android google maps application there is a very easy way to find distance between 2 locations, to do so follow the following easy steps:

1. when you first open the app go to " your timeline " from the drop menue on the top left.

2. once the new windwo opens, chose from the settings on your top right menue and choose "add place".

3. add your places and name them lilke point 1 , point 2 , or any easy name to remember.
4. once your places are added and flagged go back to the main Window in your google app.
5. click on the blue circle with the arrow in your bottom right.
6. a new windwo will open and you can see on the top there are two text fields in which you can add your "from location" and "distance location".

Here is a list of what can be pickled. In particular, functions are only picklable if they are defined at the top-level of a module.

This piece of code:

import multiprocessing as mp

class Foo():
    @staticmethod
    def work(self):
        pass

if __name__ == '__main__':   
    pool = mp.Pool()
    foo = Foo()
    pool.apply_async(foo.work)
    pool.close()
    pool.join()

yields an error almost identical to the one you posted:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 505, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/usr/lib/python2.7/multiprocessing/pool.py", line 315, in _handle_tasks
    put(task)
PicklingError: Can't pickle <type 'function'>: attribute lookup __builtin__.function failed

The problem is that the pool methods all use a mp.SimpleQueue to pass tasks to the worker processes. Everything that goes through the mp.SimpleQueue must be pickable, and foo.work is not picklable since it is not defined at the top level of the module.

It can be fixed by defining a function at the top level, which calls foo.work():

def work(foo):
    foo.work()

pool.apply_async(work,args=(foo,))

Notice that foo is pickable, since Foo is defined at the top level and foo.__dict__ is picklable.

<textarea style="resize:none" rows="10" placeholder="Enter Text" ></textarea>

To resize the image proportionally using CSS:

img.resize {
    width:540px; /* you can use % */
    height: auto;
}

This plugin can help you,

craftpip/jquery-confirm

Its easy to setup and has great set of features.

$.confirm({
    title: 'Confirm!',
    content: 'Simple confirm!',
    buttons: {
        confirm: function () {
            $.alert('Confirmed!');
        },
        cancel: function () {
            $.alert('Canceled!');
        },
        somethingElse: {
            text: 'Something else',
            btnClass: 'btn-blue',
            keys: ['enter', 'shift'], // trigger when enter or shift is pressed
            action: function(){
                $.alert('Something else?');
            }
        }
    }
});

Other than this you can also load your content from a remote url.

$.confirm({
    content: 'url:hugedata.html' // location of your hugedata.html.
});

Use execfile for Python 2:

>>> execfile('C:\\test.py')

.joins works as database join and it joins two or more table and fetch selected data from backend(database).

.includes work as left join of database. It loaded all the records of left side, does not have relevance of right hand side model. It is used to eager loading because it load all associated object in memory. If we call associations on include query result then it does not fire a query on database, It simply return data from memory because it have already loaded data in memory.

Unless you can get PHP to label that element with a class you are better to use jQuery.

jQuery(document).ready(function () {
  $count =  jQuery("ul li").size() - 1;
  alert($count);
  jQuery("ul li:nth-child("+$count+")").css("color","red");
});

If you have

dict = {key1:value1, key2:value2, key3:value3,...}

In Python 2, dict.items() copies each tuples and returns the list of tuples in dictionary i.e. [(key1,value1), (key2,value2), ...]. Implications are that the whole dictionary is copied to new list containing tuples

dict = {i: i * 2 for i in xrange(10000000)}  
# Slow and memory hungry.
for key, value in dict.items():
    print(key,":",value)

dict.iteritems() returns the dictionary item iterator. The value of the item returned is also the same i.e. (key1,value1), (key2,value2), ..., but this is not a list. This is only dictionary item iterator object. That means less memory usage (50% less).

• Lists as mutable snapshots: d.items() -> list(d.items())
• Iterator objects: d.iteritems() -> iter(d.items())

The tuples are the same. You compared tuples in each so you get same.

dict = {i: i * 2 for i in xrange(10000000)}  
# More memory efficient.
for key, value in dict.iteritems():
    print(key,":",value)

In Python 3, dict.items() returns iterator object. dict.iteritems() is removed so there is no more issue.

I had your issue, i fixed it . this error comes when your target api level is not completely downloaded . you have two ways: go to your SDK menu and download all of the android 9 components or the better way is go to your build.gradle(Module app) and change it like this:But remember, before applying these changes, make sure you have fully downloaded api lvl 8

I was wondering if it is possible to execute something like this using JDBC.

"SELECT FROM * TABLE;INSERT INTO TABLE;"

Yes it is possible. There are two ways, as far as I know. They are

1. By setting database connection property to allow multiple queries, separated by a semi-colon by default.
2. By calling a stored procedure that returns cursors implicit.

Following examples demonstrate the above two possibilities.

Example 1: ( To allow multiple queries ):

While sending a connection request, you need to append a connection property allowMultiQueries=true to the database url. This is additional connection property to those if already exists some, like autoReConnect=true, etc.. Acceptable values for allowMultiQueries property are true, false, yes, and no. Any other value is rejected at runtime with an SQLException.

String dbUrl = "jdbc:mysql:///test?allowMultiQueries=true";  

Unless such instruction is passed, an SQLException is thrown.

You have to use execute( String sql ) or its other variants to fetch results of the query execution.

boolean hasMoreResultSets = stmt.execute( multiQuerySqlString );

To iterate through and process results you require following steps:

READING_QUERY_RESULTS: // label  
    while ( hasMoreResultSets || stmt.getUpdateCount() != -1 ) {  
        if ( hasMoreResultSets ) {  
            Resultset rs = stmt.getResultSet();
            // handle your rs here
        } // if has rs
        else { // if ddl/dml/...
            int queryResult = stmt.getUpdateCount();  
            if ( queryResult == -1 ) { // no more queries processed  
                break READING_QUERY_RESULTS;  
            } // no more queries processed  
            // handle success, failure, generated keys, etc here
        } // if ddl/dml/...

        // check to continue in the loop  
        hasMoreResultSets = stmt.getMoreResults();  
    } // while results

Example 2: Steps to follow:

1. Create a procedure with one or more select, and DML queries.
2. Call it from java using CallableStatement.
3. You can capture multiple ResultSets executed in procedure.
   DML results can't be captured but can issue another select
   to find how the rows are affected in the table.

Sample table and procedure:

mysql> create table tbl_mq( i int not null auto_increment, name varchar(10), primary key (i) );
Query OK, 0 rows affected (0.16 sec)

mysql> delimiter //
mysql> create procedure multi_query()
    -> begin
    ->  select count(*) as name_count from tbl_mq;
    ->  insert into tbl_mq( names ) values ( 'ravi' );
    ->  select last_insert_id();
    ->  select * from tbl_mq;
    -> end;
    -> //
Query OK, 0 rows affected (0.02 sec)
mysql> delimiter ;
mysql> call multi_query();
+------------+
| name_count |
+------------+
|          0 |
+------------+
1 row in set (0.00 sec)

+------------------+
| last_insert_id() |
+------------------+
|                3 |
+------------------+
1 row in set (0.00 sec)

+---+------+
| i | name |
+---+------+
| 1 | ravi |
+---+------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

Call Procedure from Java:

CallableStatement cstmt = con.prepareCall( "call multi_query()" );  
boolean hasMoreResultSets = cstmt.execute();  
READING_QUERY_RESULTS:  
    while ( hasMoreResultSets ) {  
        Resultset rs = stmt.getResultSet();
        // handle your rs here
    } // while has more rs

In my case I used another solution.

As the project doesn't require CommonJS and it must have ES3 compatibility (modules not supported) all you need is just remove all export and import statements from your code, because your tsconfig doesn't contain

"module": "commonjs"

But use import and export statements in your referenced files

import { Utils } from "./utils"
export interface Actions {}

Final generated code will always have(at least for TypeScript 3.0) such lines

"use strict";
exports.__esModule = true;
var utils_1 = require("./utils");
....
utils_1.Utils.doSomething();

In my case this was a syntax issue in the .yml file. I had:

@Value("${spring.kafka.bootstrap-servers}")
public List<String> BOOTSTRAP_SERVERS_LIST;

and the list in my .yml file:

bootstrap-servers:
  - s1.company.com:9092
  - s2.company.com:9092
  - s3.company.com:9092

was not reading into the @Value-annotated field. When I changed the syntax in the .yml file to:

bootstrap-servers >
  s1.company.com:9092
  s2.company.com:9092
  s3.company.com:9092

it worked fine.

Here's an example where I found the replace( ) function helpful for giving me insight. The problem required a long integer vector be changed into a character vector and with its integers replaced by given character values.

## figuring out replace( )
(test <- c(rep(1,3),rep(2,2),rep(3,1)))

which looks like

[1] 1 1 1 2 2 3

and I want to replace every 1 with an A and 2 with a B and 3 with a C

letts <- c("A","B","C")

so in my own secret little "dirty-verse" I used a loop

for(i in 1:3)
{test <- replace(test,test==i,letts[i])}

which did what I wanted

test
[1] "A" "A" "A" "B" "B" "C"

In the first sentence I purposefully left out that the real objective was to make the big vector of integers a factor vector and assign the integer values (levels) some names (labels).

So another way of doing the replace( ) application here would be

(test <- factor(test,labels=letts))
[1] A A A B B C
Levels: A B C

Program prints ab, goes back one character and prints si overwriting the b resulting asi. Carriage return returns the caret to the first column of the current line. That means the ha will be printed over as and the result is hai

I am using using Ubuntu.

Problem for me solved by using sudo in terminal with the command.

Install this nuget package from Microsoft System.Net.Http.Json. It contains extension methods.

Then add using System.Net.Http.Json

Now, you'll be able to see these methods:

So you can now do this:

await httpClient.GetFromJsonAsync<IList<WeatherForecast>>("weatherforecast");

Using split(), you just have to change what you wish to split on.

public static String reverseString(String str)
{
    String[] rstr;
    String result = "";
    int count = 0;
    rstr = str.split(" ");
    String words[] = new String[rstr.length];
    for(int i = rstr.length-1; i >= 0; i--)
    {
        words[count] = rstr[i];
        count++;
    }

    for(int j = 0; j <= words.length-1; j++)
    {
        result += words[j] + " ";
    }

    return result;


}

In addition to the other answers, which I subscribe, you may consider using the /I switch of the IF command.

... the /I switch, if specified, says to do case insensitive string compares.

it may be of help if you want to give case insensitive flexibility to your users to specify the parameters.

IF /I "%1"=="-b" GOTO SPECIFIC

for file in *.dat ; do mv $file ${file//ABC/XYZ} ; done

No rename or sed needed. Just bash parameter expansion.

I agree with others that it's likely how you're accessing the elements that is the problem. Quoting the file names in the array assignment is correct:

FILES=(
  "2011-09-04 21.43.02.jpg"
  "2011-09-05 10.23.14.jpg"
  "2011-09-09 12.31.16.jpg"
  "2011-09-11 08.43.12.jpg"
)

for f in "${FILES[@]}"
do
  echo "$f"
done

Using double quotes around any array of the form "${FILES[@]}" splits the array into one word per array element. It doesn't do any word-splitting beyond that.

Using "${FILES[*]}" also has a special meaning, but it joins the array elements with the first character of $IFS, resulting in one word, which is probably not what you want.

Using a bare ${array[@]} or ${array[*]} subjects the result of that expansion to further word-splitting, so you'll end up with words split on spaces (and anything else in $IFS) instead of one word per array element.

Using a C-style for loop is also fine and avoids worrying about word-splitting if you're not clear on it:

for (( i = 0; i < ${#FILES[@]}; i++ ))
do
  echo "${FILES[$i]}"
done

Here is the solution and the best practice:

You need to create a resources folder where you can keep all your files you want to copy.

+-- Dockerfile
+-- resources
¦     +-- file1.txt
¦     +-- file2.js

The command for copying files should be specified this way:

COPY resources /root/folder/

where

*resources - your local folder which you created in the same folder where Dockerfile is

*/root/folder/ - folder at your container

While I enjoy using dplyr for interactive use, I find it extraordinarily tricky to do this using dplyr because you have to go through hoops to use lazyeval::interp(), setNames, etc. workarounds.

Here is a simpler version using base R, in which it seems more intuitive, to me at least, to put the loop inside the function, and which extends @MrFlicks's solution.

multipetal <- function(df, n) {
   for (i in 1:n){
      varname <- paste("petal", i , sep=".")
      df[[varname]] <- with(df, Petal.Width * i)
   }
   df
}
multipetal(iris, 3) 

I would use a https://docs.flutter.io/flutter/widgets/Stack-class.html to be able to freely position widgets.

To create circles

  new BoxDecoration(
    color: effectiveBackgroundColor,
    image: backgroundImage != null
      ? new DecorationImage(image: backgroundImage, fit: BoxFit.cover)
      : null,
    shape: BoxShape.circle,
  ),

and https://docs.flutter.io/flutter/widgets/Transform/Transform.rotate.html to position the white dots.

My suggestion is to manage docker, with docker compose. Is an easy to way to manage all the docker's containers for your project, you can map the versions and link different containers to work together.

The docs are very simple to understand, better than docker's docs.

If a path may contain parentheses then the r'\(.*?\)' regex is not enough:

import os, re

def remove_parenthesized_chunks(path, safeext=True, safedir=True):
    dirpath, basename = os.path.split(path) if safedir else ('', path)
    name, ext = os.path.splitext(basename) if safeext else (basename, '')
    name = re.sub(r'\(.*?\)', '', name)
    return os.path.join(dirpath, name+ext)

By default the function preserves parenthesized chunks in directory and extention parts of the path.

Example:

>>> f = remove_parenthesized_chunks
>>> f("Example_file_(extra_descriptor).ext")
'Example_file_.ext'
>>> path = r"c:\dir_(important)\example(extra).ext(untouchable)"
>>> f(path)
'c:\\dir_(important)\\example.ext(untouchable)'
>>> f(path, safeext=False)
'c:\\dir_(important)\\example.ext'
>>> f(path, safedir=False)
'c:\\dir_\\example.ext(untouchable)'
>>> f(path, False, False)
'c:\\dir_\\example.ext'
>>> f(r"c:\(extra)\example(extra).ext", safedir=False)
'c:\\\\example.ext'

In case anyone needs a POSIX compliant way of doing this, without needing git executable:

git-root:

#$1: Path to child directory
git_root_recurse_parent() {
    # Check if cwd is a git root directory
    if [ -d .git/objects -a -d .git/refs -a -f .git/HEAD ] ; then
        pwd
        return 0
    fi

    # Check if recursion should end (typically if cwd is /)
    if [ "${1}" = "$(pwd)" ] ; then
        return 1
    fi

    # Check parent directory in the same way
    local cwd=$(pwd)
    cd ..
    git_root_recurse_parent "${cwd}"
}

git_root_recurse_parent

If you just want the functionality as part of a script, remove the shebang, and replace the last git_root_recurse_parent line with:

git_root() {
    (git_root_recurse_parent)
}

I recently encountered this problem and stumbled upon this question.

I resolved it with a much easier way.

Method One

You can either remove the dataType: 'json' property from the object literal...

Method Two

Or you can do what @Sagiv was saying by returning your data as Json.

The reason why this parsererror message occurs is that when you simply return a string or another value, it is not really Json, so the parser fails when parsing it.

So if you remove the dataType: json property, it will not try to parse it as Json.

With the other method if you make sure to return your data as Json, the parser will know how to handle it properly.

tl;dr use this: https://jsfiddle.net/57tmy8j3/

If you're interested why or what other options there are, read on.

Quick'n'dirty - remove :hover styles using JS

You can remove all the CSS rules containing :hover using Javascript. This has the advantage of not having to touch CSS and being compatible even with older browsers.

function hasTouch() {
  return 'ontouchstart' in document.documentElement
         || navigator.maxTouchPoints > 0
         || navigator.msMaxTouchPoints > 0;
}

if (hasTouch()) { // remove all the :hover stylesheets
  try { // prevent exception on browsers not supporting DOM styleSheets properly
    for (var si in document.styleSheets) {
      var styleSheet = document.styleSheets[si];
      if (!styleSheet.rules) continue;

      for (var ri = styleSheet.rules.length - 1; ri >= 0; ri--) {
        if (!styleSheet.rules[ri].selectorText) continue;

        if (styleSheet.rules[ri].selectorText.match(':hover')) {
          styleSheet.deleteRule(ri);
        }
      }
    }
  } catch (ex) {}
}

Limitations: stylesheets must be hosted on the same domain (that means no CDNs). Disables hovers on mixed mouse & touch devices like Surface or iPad Pro, which hurts the UX.

CSS-only - use media queries

Place all your :hover rules in a @media block:

@media (hover: hover) {
  a:hover { color: blue; }
}

or alternatively, override all your hover rules (compatible with older browsers):

a:hover { color: blue; }

@media (hover: none) {
  a:hover { color: inherit; }
}

Limitations: works only on iOS 9.0+, Chrome for Android or Android 5.0+ when using WebView. hover: hover breaks hover effects on older browsers, hover: none needs overriding all the previously defined CSS rules. Both are incompatible with mixed mouse & touch devices.

The most robust - detect touch via JS and prepend CSS :hover rules

This method needs prepending all the hover rules with body.hasHover. (or a class name of your choice)

body.hasHover a:hover { color: blue; }

The hasHover class may be added using hasTouch() from the first example:

if (!hasTouch()) document.body.className += ' hasHover'

However, this whould have the same drawbacks with mixed touch devices as previous examples, which brings us to the ultimate solution. Enable hover effects whenever a mouse cursor is moved, disable hover effects whenever a touch is detected.

function watchForHover() {
  // lastTouchTime is used for ignoring emulated mousemove events
  let lastTouchTime = 0

  function enableHover() {
    if (new Date() - lastTouchTime < 500) return
    document.body.classList.add('hasHover')
  }

  function disableHover() {
    document.body.classList.remove('hasHover')
  }

  function updateLastTouchTime() {
    lastTouchTime = new Date()
  }

  document.addEventListener('touchstart', updateLastTouchTime, true)
  document.addEventListener('touchstart', disableHover, true)
  document.addEventListener('mousemove', enableHover, true)

  enableHover()
}

watchForHover()

This should work basically in any browser and enables/disables hover styles as needed.

Here's the full example - modern: https://jsfiddle.net/57tmy8j3/
Legacy (for use with old browsers): https://jsfiddle.net/dkz17jc5/19/

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

Example code for node.js - async function to sync function:

var deasync = require('deasync');

function syncFunc()
{
    var ret = null;
    asyncFunc(function(err, result){
        ret = {err : err, result : result}
    });

    while((ret == null))
    {
         deasync.runLoopOnce();
    }

    return (ret.err || ret.result);
}

You can also save it to a string buffer and then do as you wish with it,

import cStringIO
data = json.loads(request.POST['imgData'])  # Getting the object from the post request
image_output = cStringIO.StringIO()
image_output.write(data.decode('base64'))   # Write decoded image to buffer
image_output.seek(0)  # seek beginning of the image string
# image_output.read()  # Do as you wish with it!

In django, you can save it as an uploaded file to save to a model:

from django.core.files.uploadedfile import SimpleUploadedFile
suf = SimpleUploadedFile('uploaded_file.png', image_output.read(), content_type='image/png')

Or send it as an email:

email = EmailMessage('Hello', 'Body goes here', '[email protected]',
                                     ['[email protected]', ])
                email.attach('design.png', image_output.read(), 'image/png')
                email.send()

This will be possible with setiosflags(ios::showpoint).

import("time")

layout := "2006-01-02T15:04:05.000Z"
str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(layout, str)
if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

gives:

>> 2014-11-12 11:45:26.371 +0000 UTC

Use

white-space: pre-line;

It will prevent text from flowing out of the div. It will break the text as it reaches the end of the div.

If you are using the Prototype Framework, you can use the intersect method of an array to find out of they are the same (regardless of the order):

var array1 = [1,2];
var array2 = [2,1];

if(array1.intersect(array2).length === array1.length) {
    alert("arrays are the same!");
}

This is the code with two bug fixes. The first bug fix was mentioned by Royi Namir in the comment on the accepted answer to this question. The bug is described on StackOverflow at Bug in Trigger Code. The second one was found by @Fandango68 and fixes columns with multiples words for their names.

Assuming your page size is 20 record, and you wanna get page number 2, here is how you would do it:

SQL Server, Oracle:

SELECT *   -- <-- pick any columns here from your table, if you wanna exclude the RowNumber
FROM (SELECT ROW_NUMBER OVER(ORDER BY ID DESC) RowNumber, * 
      FROM Reflow  
      WHERE ReflowProcessID = somenumber) t
WHERE RowNumber >= 20 AND RowNumber <= 40    

MySQL:

SELECT * 
FROM Reflow  
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC
LIMIT 20 OFFSET 20

Below I have shown an example using both Ref and out. Now, you all will be cleared about ref and out.

In below mentioned example when i comment //myRefObj = new myClass { Name = "ref outside called!! " }; line, will get an error saying "Use of unassigned local variable 'myRefObj'", but there is no such error in out.

Where to use Ref: when we are calling a procedure with an in parameter and the same parameter will be used to store the output of that proc.

Where to use Out: when we are calling a procedure with no in parameter and teh same param will be used to return the value from that proc. Also note the output

public partial class refAndOutUse : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        myClass myRefObj;
        myRefObj = new myClass { Name = "ref outside called!!  <br/>" };
        myRefFunction(ref myRefObj);
        Response.Write(myRefObj.Name); //ref inside function

        myClass myOutObj;
        myOutFunction(out myOutObj);
        Response.Write(myOutObj.Name); //out inside function
    }

    void myRefFunction(ref myClass refObj)
    {
        refObj.Name = "ref inside function <br/>";
        Response.Write(refObj.Name); //ref inside function
    }
    void myOutFunction(out myClass outObj)
    {
        outObj = new myClass { Name = "out inside function <br/>" }; 
        Response.Write(outObj.Name); //out inside function
    }
}

public class myClass
{
    public string Name { get; set; }
} 

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

We can generate tuples from a list comprehension. The following one adds two numbers sequentially into a tuple and gives a list from numbers 0-9.

>>> print k
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99]
>>> r= [tuple(k[i:i+2]) for i in xrange(10) if not i%2]
>>> print r
[(0, 1), (2, 3), (4, 5), (6, 7), (8, 9)]

It is easy to solve, only create an hidden submit:

<button id="submitCadastro" type="button">ENVIAR</button>
<input type="submit" id="submitCadastroHidden" style="display: none;" >

with jQuery you click the submit:

$("#submitCadastro").click(function(){
    if($("#checkDocumentos").prop("checked") == false){
        //alert("Aceite os termos e condições primeiro!.");
        $("#modalERROR").modal("show");
    }else{
        //$("#formCadastro").submit();
        $("#submitCadastroHidden").click();                     
    }
});

This functionality is part of the C++11 standard.

#include <thread>

unsigned int nthreads = std::thread::hardware_concurrency();

For older compilers, you can use the Boost.Thread library.

#include <boost/thread.hpp>

unsigned int nthreads = boost::thread::hardware_concurrency();

In either case, hardware_concurrency() returns the number of threads that the hardware is capable of executing concurrently based on the number of CPU cores and hyper-threading units.

CSV can get complicated real fast.

Use something robust and well-tested:
FileHelpers: www.filehelpers.net

The FileHelpers are a free and easy to use .NET library to import/export data from fixed length or delimited records in files, strings or streams.

after you have pulled and updated your workspace do a thg and right click on the change set you want to get rid of and then click modify history -> strip, it will remove the change set and you will point to default tip.

Here is the solution:

1. Login to DB;
2. Run a command show full processlist;to get the process id with status and query itself which causes the database hanging;
3. Select the process id and run a command KILL <pid>; to kill that process.

Sometimes it is not enough to kill each process manually. So, for that we've to go with some trick:

1. Login to MySQL;
2. Run a query Select concat('KILL ',id,';') from information_schema.processlist where user='user'; to print all processes with KILL command;
3. Copy the query result, paste and remove a pipe | sign, copy and paste all again into the query console. HIT ENTER. BooM it's done.

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

You can convert between a string representation of the binary using bin() and int()

>>> bin(88)
'0b1011000'
>>> int('0b1011000', 2)
88
>>> 

>>> a=int('01100000', 2)
>>> b=int('00100110', 2)
>>> bin(a & b)
'0b100000'
>>> bin(a | b)
'0b1100110'
>>> bin(a ^ b)
'0b1000110'

With the React Devtools installed you can run this from the browser console:

__REACT_DEVTOOLS_GLOBAL_HOOK__.renderers.forEach(r => console.log(`${r.rendererPackageName}: ${r.version}`))

Which outputs something like:

react-dom: 16.12.0

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

To make the text on the tick labels fully visible and read in the same direction as the y-axis label, change the last line to

q + theme(axis.text.x=element_text(angle=90, hjust=1))

After looking in question, you should not use 404 why?

Based on RFC 7231 the correct status code is 204

In the anwsers above I noticed 1 small missunderstanding:

1.- the resource is: /users

2.- /users/8 is not the resource, this is: the resource /users with route parameter 8, consumer maybe cannot notice it and does not know the difference, but publisher does and must know this!... so he must return an accurate response for consumers. period.

so:

Based on the RFC: 404 is incorrect because the resources /users is found, but the logic executed using the parameter 8 did not found any content to return as a response, so the correct answer is: 204

The main point here is: 404 not even the resource was found to process the internal logic

204 is a: I found the resource, the logic was executed but I did not found any data using your criteria given in the route parameter so I cant return anything to you. Im sorry, verify your criteria and call me again.

200: ok i found the resource, the logic was executed (even when Im not forced to return anything) take this and use it at your will.

205: (the best option of a GET response) I found the resource, the logic was executed, I have some content for you, use it well, oh by the way if your are going to share this in a view please refresh the view to display it.

Hope it helps.

Use the following JS:

$(document).ready(function () {
    $("#btnsubmit").click(function () {

             $.ajax({
                 type: "POST",
                 url: '/Plan/PlanManage',     //your action
                 data: $('#PlanForm').serialize(),   //your form name.it takes all the values of model               
                 dataType: 'json',
                 success: function (result) {
                     console.log(result);
                 }
             })
        return false;
    });
});

and the following code on your controller:

[HttpPost]
public string PlanManage(Plan objplan)  //model plan
{

A Dictionary is a Hash Table, so you have no idea the order of insertion!

If you want to know the last inserted key I would suggest extending the Dictionary to include a LastKeyInserted value.

E.g.:

public MyDictionary<K, T> : IDictionary<K, T>
{
    private IDictionary<K, T> _InnerDictionary;

    public K LastInsertedKey { get; set; }

    public MyDictionary()
    {
        _InnerDictionary = new Dictionary<K, T>();
    }

    #region Implementation of IDictionary

    public void Add(KeyValuePair<K, T> item)
    {
        _InnerDictionary.Add(item);
        LastInsertedKey = item.Key;

    }

    public void Add(K key, T value)
    {
        _InnerDictionary.Add(key, value);
        LastInsertedKey = key;
    }

    .... rest of IDictionary methods

    #endregion

}

You will run into problems however when you use .Remove() so to overcome this you will have to keep an ordered list of the keys inserted.

In addition to xzyfer's answer

The function

function custom_unset(&$array=array(), $key=0) {
    if(isset($array[$key])){

        // remove item at index
        unset($array[$key]);

        // 'reindex' array
        $array = array_values($array);

        //alternatively
        //$array = array_merge($array); 

    }
    return $array;
}

Use

$my_array=array(
    0=>'test0', 
    1=>'test1', 
    2=>'test2'
);

custom_unset($my_array, 1);

Result

 array(2) {
    [0]=>
    string(5) "test0"
    [1]=>
    string(5) "test2"
  }

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

Eclipse has built in JUnit functionality. Open your Run Configuration manager to create a test to run. You can also create JUnit Test Cases/Suites from New->Other.

Try to create remote origin first, maybe is missing because you change name of the remote repo

git remote add origin URL_TO_YOUR_REPO

Backtrace dumps a whole lot of garbage that you don't need. It takes is very long, difficult to read. All you usuall ever want is "what called what from where?" Here is a simple static function solution. I usually put it in a class called 'debug', which contains all of my debugging utility functions.

class debugUtils {
    public static function callStack($stacktrace) {
        print str_repeat("=", 50) ."\n";
        $i = 1;
        foreach($stacktrace as $node) {
            print "$i. ".basename($node['file']) .":" .$node['function'] ."(" .$node['line'].")\n";
            $i++;
        }
    } 
}

You call it like this:

debugUtils::callStack(debug_backtrace());

And it produces output like this:

==================================================
 1. DatabaseDriver.php::getSequenceTable(169)
 2. ClassMetadataFactory.php::loadMetadataForClass(284)
 3. ClassMetadataFactory.php::loadMetadata(177)
 4. ClassMetadataFactory.php::getMetadataFor(124)
 5. Import.php::getAllMetadata(188)
 6. Command.php::execute(187)
 7. Application.php::run(194)
 8. Application.php::doRun(118)
 9. doctrine.php::run(99)
 10. doctrine::include(4)
==================================================

If you used [STAThread] to the main entry of your application and still get the error you may need to make a Thread-Safe call to the control... something like below. In my case with the same problem the following solution worked!

Private void YourFunc(..)
{
    if (this.InvokeRequired)
    {
        Invoke(new MethodInvoker(delegate()
        {
           // Call your method YourFunc(..);
        }));
    }
    else
    {
        ///
    }

However, I got curious to what each class contained and when I try to open one of the classes in the jar file, it tells me that I need a source file.

A jar file is basically a zip file containing .class files and potentially other resources (and metadata about the jar itself). It's hard to compare C to Java really, as Java byte code maintains a lot more metadata than most binary formats - but the class file is compiled code instead of source code.

If you either open the jar file with a zip utility or run jar xf foo.jar you can extract the files from it, and have a look at them. Note that you don't need a jar file to run Java code - classloaders can load class data directly from the file system, or from URLs, as well as from jar files.

There is an issue in php version less than 5.2.6. You may need to upgrade the version of php.

yum install MySQL-python.x86_64

worked for me.

!important is a part of CSS1.

Browsers supporting it: IE5.5+, Firefox 1+, Safari 3+, Chrome 1+.

It means, something like:

Use me, if there is nothing important else around!

Cant say it better.

You might no need to having export, just add this line in catalina.sh :

CATALINA_OPTS="-Xms512M -Xmx1024M"

It looks like it only works in Internet Explorer, but a quick Google search for "html embed fonts" yields http://www.spoono.com/html/tutorials/tutorial.php?id=19

If you want to stay platform-agnostic (and you should!) you'll have to use images, or else just use a standard font.

As much as your available memory will allow. There's no size limit except for the heap.

git whatchanged seems to be a good alternative.

Please try this which it works for me.

return [] as Criminal[];

1. Added path to ~/.zshrc

   sudo vi ~/.zshrc

   add new path

   export PATH="$PATH:[NEW_DIRECTORY]/bin"
   

2. Update ~/.zshrc

   Save ~/.zshrc

   source ~/.zshrc

3. Check PATH

   echo $PATH

set the target attribute of your <a> element to "_tab"

EDIT: It works, however W3Schools says there is no such target attribute: http://www.w3schools.com/tags/att_a_target.asp

EDIT2: From what I've figured out from the comments. setting target to _blank will take you to a new tab or window (depending on your browser settings). Typing anything except one of the ones below will create a new tab group (I'm not sure how these work):

_blank  Opens the linked document in a new window or tab
_self   Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame
_top    Opens the linked document in the full body of the window
framename   Opens the linked document in a named frame

How about

a["abc"] = [1, 2]

This will result in:

>>> a
{'abc': [1, 2]}

Is that what you were looking for?

From the menu bar, Window → Show View → Console. Alternately, use the keyboard shortcut:

• Mac: Option-Command-Q, then C, or
• Windows: Alt-Shift-Q, then C

One could use the queryParam method, passing it parameter name and an array of values:

    public WebTarget queryParam(String name, Object... values);

Example (jersey-client 2.23.2):

    WebTarget target = ClientBuilder.newClient().target(URI.create("http://localhost"));
    target.path("path")
            .queryParam("param_name", Arrays.asList("paramVal1", "paramVal2").toArray())
            .request().get();

This will issue request to following URL:

    http://localhost/path?param_name=paramVal1&param_name=paramVal2

Just a remark about your saying

Hi, I tried searching a way to insert information in multiple tables in the same query

Do you eat all your lunch dishes mixed with drinks in the same bowl?
I suppose - no.

Same here.
There are things we do separately.
2 insert queries are 2 insert queries. It's all right. Nothing wrong with it. No need to mash it in one.
Same for select. Query must be sensible and do it's job. That's the only reasons. Number of queries is not.

As for the transactions - you may use them, but it's not THAT big deal for the average web-site. If it happened once a year (if ever) that one user registration being broken you'll be able to fix, no doubt.
there are hundreds of thousands sites running mysql with no transaction support driver. Have you heard of terrible disasters breaking these sites apart? Me neither.

And mysql_insert_id() has noting to do with transactions. you may include in into transaction all right. it's just different matters. Someone raised this question out of nowhere.

This is an async method which first checks for the availability of arrayBuffer method. This function is backward compatible and future proof.

async function blobToArrayBuffer(blob) {
    if ('arrayBuffer' in blob) return await blob.arrayBuffer();
    
    return new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = () => resolve(reader.result);
        reader.onerror = () => reject;
        reader.readAsArrayBuffer(blob);
    });
}

I don't know about php but i belive the problem is from this :

echo '<script language="javascript>';
echo 'alery("message successfully sent")';
echo '</script>';

Try to change this with :

echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
