Swing + SwingX + Miglayout is my combination of choice. Miglayout is so much simpler than Swings perceived 200 different layout managers and much more powerful. Also, it provides you with the ability to "debug" your layouts, which is especially handy when creating complex layouts.

The simplest is always the best:

Select EmployeeID*1 as EmployeeID

The Strings in double quotes always confuse me, so I think answer to this question needs some graphical presentation to clear this out.

For a banking app, I have a LoginViewController and a BalanceViewController. Each have their respective screens.

The app starts and shows the Login screen. When login is successful, app opens the Balance screen.

Here is how it looks:

The login success is handled like this:

let storyBoard: UIStoryboard = UIStoryboard(name: "Balance", bundle: nil)
let balanceViewController = storyBoard.instantiateViewController(withIdentifier: "balance") as! BalanceViewController
self.present(balanceViewController, animated: true, completion: nil)

As you can see, the storyboard ID 'balance' in small letters is what goes in the second line of the code, and this is the ID which is defined in the storyboard settings, as in the attached screenshot.

The term 'Balance' with capital 'B' is the name of the storyboard file, which is used in the first line of the code.

We know that using hard coded Strings in code is a very bad practice, but somehow in iOS development it has become a common practice, and Xcode doesn't even warn about them.

Swift and Xcode 10+

#if DEBUG will pass in ANY development/ad-hoc build, device or simulator. It's only false for App Store and TestFlight builds.

Example:

#if DEBUG
   print("Not App Store build")
#else
   print("App Store build")
#endif

public MainPage()
{
    this.InitializeComponent();
    ...
    ...
    ...
    //Make Start result text copiable
    TextBlockStatusStart.IsTextSelectionEnabled = true;
}

Remove the max-width from the body, and put it to the #container.

So, instead of:

body {
    max-width:1250px;
}

You should have:

#container {
    max-width:1250px;
}

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

If you want to alter the original objects, then a simple Array#forEach will do:

rockets.forEach(function(rocket) {
    rocket.launches += 10;
});

If you want to keep the original objects unaltered, then use Array#map and copy the objects using Object#assign:

var newRockets = rockets.forEach(function(rocket) {
    var newRocket = Object.assign({}, rocket);
    newRocket.launches += 10;
    return newRocket;
});

A website is now online with all the TSDoc syntax available (and that's awesome): https://tsdoc.org/

For reference, old answer:

The right syntax is now the one used by TSDoc. It will allow you to have your comments understood by Visual Studio Code or other documentation tools.

Note: you should not use JSDoc, as explained on TSDoc main page: Why can't JSDoc be the standard? Unfortunately, the JSDoc grammar is not rigorously specified but rather inferred from the behavior of a particular implementation. The majority of the standard JSDoc tags are preoccupied with providing type annotations for plain JavaScript, which is an irrelevant concern for a strongly-typed language such as TypeScript. TSDoc addresses these limitations while also tackling a more sophisticated set of goals.

Felipsmartins is correct.

It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.

Which means you can do this:

curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'

Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.

I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.

curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros

This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)

Hope it helps.

The usage is exactly like @prasad asked

This is a simpler way using iloc to select which columns to sum:

df['f']=df.iloc[:,0:2].sum(axis=1)
df['g']=df.iloc[:,[0,1]].sum(axis=1)
df['h']=df.iloc[:,[0,3]].sum(axis=1)

Produces:

   a  b   c  d   e  f  g   h
0  1  2  dd  5   8  3  3   6
1  2  3  ee  9  14  5  5  11
2  3  4  ff  1   8  7  7   4

I can't find a way to combine a range and specific columns that works e.g. something like:

df['i']=df.iloc[:,[[0:2],3]].sum(axis=1)
df['i']=df.iloc[:,[0:2,3]].sum(axis=1)

Mathew's answer works for the terminal python shell, but it didn't work for IDLE shell in my case because many versions of python existed before I replaced them all with Python2.7.7. How I solved the problem with IDLE.

1. In terminal, cd /Applications/Python\ 2.7/IDLE.app/Contents/Resources/
2. then sudo nano idlemain.py, enter password if required.
3. after os.chdir(os.path.expanduser('~/Documents')) this line, I added sys.path.append("/Users/admin/Downloads....") NOTE: replace contents of the quotes with the directory where python module to be added
4. to save the change, ctrl+x and enter Now open idle and try to import the python module, no error for me!!!

As the 'margin' doesn't work in Chrome, that's why I used 'border' instead.

br {
  display: block;
  content: "";
  border-bottom: 10px solid transparent; // Works in Chrome/Safari
}
@-moz-document url-prefix() {
  br {
    margin-bottom: 10px; // As 'border-bottom' doesn't work in firefox and 'margin-bottom' doesn't work in Chrome/Safari.
  }
}

request.getParameterValues("select2") returns an array of all submitted values.

Using React Hooks / Functional components with Typescript, you can use the useRef hook with HTMLInputElement as the generic parameter of useRef:

import React, { useEffect, useRef } from 'react';

export default function MyComponent(): JSX.Element {
    const inputReference = useRef<HTMLInputElement>(null);

    useEffect(() => {
        inputReference.current?.focus();
    }, []);

    return (
        <div>
            <input ref={inputReference} />
        </div>
    );
}

Or if using reactstrap, supply inputReference to innerRef instead of ref:

import React, { useEffect, useRef } from 'react';
import { Input } from 'reactstrap';

export default function MyComponent(): JSX.Element {
    const inputReference = useRef<HTMLInputElement>(null);

    useEffect(() => {
        inputReference.current?.focus();
    }, []);

    return (
        <div>
            <Input innerRef={inputReference} />
        </div>
    );
}

I found the solution of passing param as a tag's attribute quite reasonable.

However it has limitations:

• Doesn't work properly when list item has other tags (thus event.target might be different to intended)
• Param could be a string only. Requires serialization and deserialization.

That's why I came up with this library: react-event-param

It:

• Solves the problem of children by searching for needed attribute in parents whenever needed
• Automatically serializes and deserializes param
• Encapsulates the logic of setting and getting. No need to mess with param names

Usage example:

import { setEventParam, getEventParam } from "react-event-param";

class List extends Component {
  onItemClick = e => {
    const index = getEventParam(e.target);
    // Do something with index
  };

  render() {
    return (
      <ul>
        {this.props.items.map((itemText, index) => (
          <li
            key={index}
            {...setEventParam(index)}
            onClick={this.onItemClick}
          >
            {{ itemText }}
          </li>
        ))}
      </ul>
    );
  }
}

export default List;

Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.

You can check this by running in Windows PowerShell:

> Get-Service ssh-agent

And then check the output of status is not running.

Status   Name               DisplayName
------   ----               -----------
Stopped  ssh-agent          OpenSSH Authentication Agent

Then check that the service has been disabled by running

> Get-Service ssh-agent | Select StartType

StartType
---------
Disabled

I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:

 > Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Alternatively, you can set it through the GUI if you prefer.

This is equivalent.

l=[..., 1,2,3]

The same as the ellipsis literal “...”. Special value used mostly in conjunction with extended slicing syntax for user-defined container data types.

From http://developer.android.com/reference/android/app/Activity.html

public final void showDialog (int id) Added in API level 1

This method was deprecated in API level 13. Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.

Simple version of showDialog(int, Bundle) that does not take any arguments. Simply calls showDialog(int, Bundle) with null arguments.

Why

• A fragment that displays a dialog window, floating on top of its activity's window. This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog.

This is for all people who need to increase the radius of ScriptIntrinsicBlur to obtain a harder gaussian blur.

Instead of to put the radius more than 25, you can scale down the image and get the same result. I wrote a class called GaussianBlur. Below you can see how to use, and the whole class implementation.

Usage:

GaussianBlur gaussian = new GaussianBlur(context);
gaussian.setMaxImageSize(60);
gaussian.setRadius(25); //max

Bitmap output = gaussian.render(<your bitmap>,true);
Drawable d = new BitmapDrawable(getResources(),output);

Class:

 public class GaussianBlur {
    private final int DEFAULT_RADIUS = 25;
    private final float DEFAULT_MAX_IMAGE_SIZE = 400;

    private Context context;
    private int radius;
    private float maxImageSize;

    public GaussianBlur(Context context) {
    this.context = context;
    setRadius(DEFAULT_RADIUS);
    setMaxImageSize(DEFAULT_MAX_IMAGE_SIZE);
    } 

    public Bitmap render(Bitmap bitmap, boolean scaleDown) {
    RenderScript rs = RenderScript.create(context);

    if (scaleDown) {
        bitmap = scaleDown(bitmap);
    }

    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Config.ARGB_8888);

    Allocation inAlloc = Allocation.createFromBitmap(rs, bitmap, Allocation.MipmapControl.MIPMAP_NONE, Allocation.USAGE_GRAPHICS_TEXTURE);
    Allocation outAlloc = Allocation.createFromBitmap(rs, output);

    ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, inAlloc.getElement()); // Element.U8_4(rs));
    script.setRadius(getRadius());
    script.setInput(inAlloc);
    script.forEach(outAlloc);
    outAlloc.copyTo(output);

    rs.destroy();

    return output;
}

public Bitmap scaleDown(Bitmap input) {
    float ratio = Math.min((float) getMaxImageSize() / input.getWidth(), (float) getMaxImageSize() / input.getHeight());
    int width = Math.round((float) ratio * input.getWidth());
    int height = Math.round((float) ratio * input.getHeight());

    return Bitmap.createScaledBitmap(input, width, height, true);
}

public int getRadius() {
    return radius;
}

public void setRadius(int radius) {
    this.radius = radius;
}

public float getMaxImageSize() {
    return maxImageSize;
}

public void setMaxImageSize(float maxImageSize) {
    this.maxImageSize = maxImageSize;
}
    }

1st Step: Go to the form where datagridview is added

2nd step: click on the datagridview at the top right side there will be displayed a small button of like play icon or arrow to edit the datagridview.

3rd step: click on that button and select edit columns now click the attributes you want to increase font size.

4th step: on the right side of the property menu the first on the list column named defaultcellstyle click on its property a new window will open to change the font and font size.

They're actually really similar. How you call them is exactly the same.The difference lies in how the browser loads them into the execution context.

Function declarations load before any code is executed.

Function expressions load only when the interpreter reaches that line of code.

So if you try to call a function expression before it's loaded, you'll get an error! If you call a function declaration instead, it'll always work, because no code can be called until all declarations are loaded.

Example: Function Expression

alert(foo()); // ERROR! foo wasn't loaded yet
var foo = function() { return 5; } 

Example: Function Declaration

alert(foo()); // Alerts 5. Declarations are loaded before any code can run.
function foo() { return 5; } 

As for the second part of your question:

var foo = function foo() { return 5; } is really the same as the other two. It's just that this line of code used to cause an error in safari, though it no longer does.

Do not use the ToList() method as in the accepted answer !

Running SQL profiler, I verified and found that ToList() function gets all the records from the database. It is really bad performance !!

I would have run this query by pure sql command as follows:

string query = "Update YourTable Set ... Where ...";    
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));

This would operate the update in one-shot without selecting even one row.

I came up with your case. This is how I sort it out

1. Install Anaconda
2. Create a virtual environment - conda create -n tensor flow
3. Go inside your virtual environment - Source activate tensorflow
4. Inside that install tensorflow. You can install it using pip
5. Finish install

So then the next thing, when you launch it:

6. If you are not inside the virtual environment type - Source Activate Tensorflow
7. Then inside this again install your Jupiter notebook and Pandas libraries, because there can be some missing in this virtual environment

Inside the virtual environment just type:

8. pip install jupyter notebook
9. pip install pandas

Then you can launch jupyter notebook saying:

10. jupyter notebook
11. Select the correct terminal python 3 or 2
12. Then import those modules

This error was caused, for me, by different circumstances. A downloaded project tutorial had a default setting of [Project]>Targets>Build Settings>Architectures>Build Active Architecture Only>Release = "Yes." I wasn't intending to build a release, so the solution was to set Release (which presumably requires not just a developer profile but distribution profile) to "No."

Here is a modified version of the StrToNumber function. As before,

1. It allows an optional sign to appear in front or behind the numeric value.
2. It performs a check to verify there is only one sign at the head or tail of the string.
3. If an error occurs, a "passed" default value is returned.

This response is a possible solution that is better suited to the initial question than my previous post.

Export one flat default

This is a great opportunity to use spread (... in { ...Matters, ...Contacts } below:

// imports/collections/Matters.js
export default {           // default export
  hello: 'World',
  something: 'important',
};

// imports/collections/Contacts.js
export default {           // default export
  hello: 'Moon',
  email: '[email protected]',
};

// imports/collections/index.js
import Matters from './Matters';      // import default export as var 'Matters'
import Contacts from './Contacts';

export default {  // default export
  ...Matters,     // spread Matters, overwriting previous properties
  ...Contacts,    // spread Contacts, overwriting previosu properties
};

// imports/test.js
import collections from './collections';  // import default export as 'collections'

console.log(collections);

Then, to run babel compiled code from the command line (from project root /):

$ npm install --save-dev @babel/core @babel/cli @babel/preset-env @babel/node 
(trimmed)

$ npx babel-node --presets @babel/preset-env imports/test.js 
{ hello: 'Moon',
  something: 'important',
  email: '[email protected]' }

Export one tree-like default

If you'd prefer to not overwrite properties, change:

// imports/collections/index.js
import Matters from './Matters';     // import default as 'Matters'
import Contacts from './Contacts';

export default {   // export default
  Matters,
  Contacts,
};

And the output will be:

$ npx babel-node --presets @babel/preset-env imports/test.js
{ Matters: { hello: 'World', something: 'important' },
  Contacts: { hello: 'Moon', email: '[email protected]' } }

Export multiple named exports w/ no default

If you're dedicated to DRY, the syntax on the imports changes as well:

// imports/collections/index.js

// export default as named export 'Matters'
export { default as Matters } from './Matters';  
export { default as Contacts } from './Contacts'; 

This creates 2 named exports w/ no default export. Then change:

// imports/test.js
import { Matters, Contacts } from './collections';

console.log(Matters, Contacts);

And the output:

$ npx babel-node --presets @babel/preset-env imports/test.js
{ hello: 'World', something: 'important' } { hello: 'Moon', email: '[email protected]' }

Import all named exports

// imports/collections/index.js

// export default as named export 'Matters'
export { default as Matters } from './Matters';
export { default as Contacts } from './Contacts';

// imports/test.js

// Import all named exports as 'collections'
import * as collections from './collections';

console.log(collections);  // interesting output
console.log(collections.Matters, collections.Contacts);

Notice the destructuring import { Matters, Contacts } from './collections'; in the previous example.

$ npx babel-node --presets @babel/preset-env imports/test.js
{ Matters: [Getter], Contacts: [Getter] }
{ hello: 'World', something: 'important' } { hello: 'Moon', email: '[email protected]' }

In practice

Given these source files:

/myLib/thingA.js
/myLib/thingB.js
/myLib/thingC.js

Creating a /myLib/index.js to bundle up all the files defeats the purpose of import/export. It would be easier to make everything global in the first place, than to make everything global via import/export via index.js "wrapper files".

If you want a particular file, import thingA from './myLib/thingA'; in your own projects.

Creating a "wrapper file" with exports for the module only makes sense if you're packaging for npm or on a multi-year multi-team project.

Made it this far? See the docs for more details.

Also, yay for Stackoverflow finally supporting three `s as code fence markup.

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

Let me know if you have a problem.

Just a note with Xcode 4: in the organizer there are two different sections in the left pane:

1. Library > Provisioning profiles

2. Devices > your device > Provisioning profiles

I was always puttings my provisioning profiles into 2. and even after cleaning and installing properly it was not working. Then I discovered 1. and finally I found the refresh button. If you select 'Automatic device provisioning' in 1. and click on refresh, then everything got validated (no yellow warning in 2. anymore).

Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec

Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec, as I have ~/bin in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...

Launch it from the root of your project, where you can see src and target dirs.

The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)

$ mvnexec 
 1) org.jmeld.ui.JMeldComponent
 2) org.jmeld.ui.text.FileDocument
 3) org.jmeld.JMeld
 4) org.jmeld.util.UIDefaultsPrint
 5) org.jmeld.util.PrintProperties
 6) org.jmeld.util.file.DirectoryDiff
 7) org.jmeld.util.file.VersionControlDiff
 8) org.jmeld.vc.svn.InfoCmd
 9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#? 

If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P)

By default it compiles project every run. but you can avoid that using mvnexec -B

It allows to search only in test classes -M or --no-main, or only in main classes -T or --no-test. also has a filter by name option -f <whatever>

Hope this could save you some time, for me it does.

If the values are integer then you can use [2-3] or you can use [5,7,8] for non continuous values.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    1)
        echo "one"
        ;;
    [2-3])
        echo "two or three"
        ;;
    [4-6])
        echo "four to six"
        ;;
    [7,9])
        echo "seven or nine"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done

If the values are string then you can use |.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    "one")
        echo "one"
        ;;
    "two" | "three")
        echo "two or three"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done

My problem was not related to skype as i didn't had it installed. The solution I found was that 2 .dll files(msvcp110.dll, msvcr110.dll) were missing from the directory :

C:\wamp\bin\apache\apache2.4.9\bin

So I copied these 2 files to all these locations just in case and restarted wamp it worked

C:\wamp
C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\apache\apache2.4.9
C:\wamp\bin\mysql\mysql5.6.17
C:\wamp\bin\php\php5.5.12

I hope this helps someone out.

We can do that using @lru_cache decorator and setrecursionlimit() method:

import sys
from functools import lru_cache

sys.setrecursionlimit(15000)


@lru_cache(128)
def fib(n: int) -> int:
    if n == 0:
        return 0
    if n == 1:
        return 1

    return fib(n - 2) + fib(n - 1)


print(fib(14000))

Output

head:

Name

head - output the first part of files

Synopsis

head [OPTION]... [FILE]...

Description

Print the first 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
-c, --bytes=[-]N print the first N bytes of each file; with the leading '-', print all but the last N bytes of each file

If you really want to use String:

NSString *number = [[NSString alloc] initWithFormat:@"%d", 123];

But I would recommend using NSNumber:

NSNumber *number = [[NSNumber alloc] initWithInt:123];

Then just add it to the array.

[array addObject:number];

Don't forget to release it after that, since you created it above.

[number release];

I've used this with great success:

under windows 2012 r2 it can be found here:

For php, when you use checkboxes for multiple values, the name always ends with []. We can use this to make the solution a bit more generic. And, since I put my error message in a data-message-value-missing attribute, I use:

$form.on('change', 'input[type=checkbox][name$="[]"]', e => {
    const $inputs = $('input[type=checkbox][name="' + e.target.name + '"]');
    const $targetInp = $inputs.filter('[data-message-value-missing]');
    if($inputs.filter(':checked').length) {
        $targetInp.removeAttr('required');
        $form.find('label.error').html('');
    } else {
        $targetInp.attr('required', 'required');
    }
});

To make this work, set the data-message-value-missing and the required on only one (the last) input:

<ul>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 1"><label>Box 1</label></li>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 2"><label>Box 2</label></li>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 3"><label>Box 3</label></li>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 4" required data-message-value-missing="Select at least one"><label>Box 4</label></li>
</ul>

I excluded the code to handle the checkValidity(), etc. Seems beyond the scope of this question...

There is a much easier way to get the smooth scroll effect without javascript. In your CSS just target the entire html tag and give it scroll-behavior: smooth;

html {_x000D_
  scroll-behavior: smooth;_x000D_
 }_x000D_
 _x000D_
 a {_x000D_
  text-decoration: none;_x000D_
  color: black;_x000D_
 } _x000D_
 _x000D_
 #down {_x000D_
  margin-top: 100%;_x000D_
  padding-bottom: 25%;_x000D_
 } 

<html>_x000D_
  <a href="#down">Click Here to Smoothly Scroll Down</a>_x000D_
  <div id="down">_x000D_
    <h1>You are down!</h1>_x000D_
  </div>_x000D_
</html

The "scroll-behavior" is telling the page how it should scroll and is so much easier than using javascript. Javascript will give you more options on speed and the smoothness but this will deliver without all of the confusing code.

Use .parentsUntil()

$(".d").parentsUntil(".a");

"Line 1" - maybe something about windows vs unix newlines? (as i saw windows 7 mentioned above).

Check this out:

db.collection.find().pretty()

I know its quite late to answer this, but I guess it will help anyone ahead.

Well using CSS3 FlexBox. It can be acheived. Make you header as display:flex and divide its entire width into 3 parts. In the first part I have placed the logo, the searchbar in second part and buttons container in last part. apply justify-content: between to the header container and flex-grow:1 to the searchbar. That's it. The sample code is below.

#header {_x000D_

use the ref-log:

git branch fixing-things HEAD@{1}
git reset fixing-things

you should then have all your previously amended changes only in your working copy and can commit again

to see a full list of previous indices type git reflog

Step-1

  Please define a method in Api interface like:-
 @FormUrlEncoded
 @POST()
 Call<RootLoginModel> getForgotPassword(
        @Url String apiname,
        @Field(ParameterConstants.email_id) String username
 );

Step-2 For a best practice define a class for retrofit instance:-

  public class ApiRequest {
       static Retrofit retrofit = null;



public static Retrofit getClient() {
    HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
    logging.setLevel(HttpLoggingInterceptor.Level.BODY);

    OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
            .addInterceptor(logging)
            .connectTimeout(60, TimeUnit.SECONDS)
            .readTimeout(60, TimeUnit.SECONDS)
            .writeTimeout(60, TimeUnit.SECONDS)
            .build();

    if (retrofit==null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(URLConstants.base_url)
                .client(okHttpClient)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}

} Step-3 define in your activity:-

  final APIService request =ApiRequest.getClient().create(APIService.class);
  Call<RootLoginModel> call = request.getForgotPassword("dynamic api 
  name",strEmailid);

Not a direct answer to your question, but you can get the most commonly used utilities from http://www.mingw.org/ without having to jump through the hoops with that horrible Cygwin installer.

Here is a slightly more informative link http://sourceforge.net/apps/mediawiki/cobcurses/index.php?title=Install-MSYS.

You can use sp_lock (and sp_lock2), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks:

select  
    object_name(p.object_id) as TableName, 
    resource_type, resource_description
from
    sys.dm_tran_locks l
    join sys.partitions p on l.resource_associated_entity_id = p.hobt_id

Here is a function that takes in another function and outputs a version that runs async.

var async = function (func) {
  return function () {
    var args = arguments;
    setTimeout(function () {
      func.apply(this, args);
    }, 0);
  };
};

It is used as a simple way to make an async function:

var anyncFunction = async(function (callback) {
    doSomething();
    callback();
});

This is different from @fider's answer because the function itself has its own structure (no callback added on, it's already in the function) and also because it creates a new function that can be used.

Considering the question specifies UNIX, not Linux, use of a stat binary is not necessary. The solution below works on a very old UNIX, though a shell other than sh (i.e. bash) was necessary. It is a derivation of glenn jackman's perl stat solution. It seems like an alternative worth exploring for conciseness.

$ alias lls='llsfn () { while test $# -gt 0; do perl -s -e \
  '\''@fields = stat "$f"; printf "%04o\t", $fields[2] & 07777'\'' \
    -- -f=$1; ls -ld $1; shift; done; unset -f llsf; }; llsfn'
$ lls /tmp /etc/resolv.conf
1777    drwxrwxrwt   7 sys      sys       246272 Nov  5 15:10 /tmp
0644    -rw-r--r--   1 bin      bin           74 Sep 20 23:48 /etc/resolv.conf

The alias was developed using information in this answer

The whole answer is a modified version of a solution in this answer

You need to open TCP port 8787 in the ec2 Security Group. Also need to open the same port on the EC2 instance's firewall.

You can use:

arr - [arr[0]]

or

arr - [arr.shift]

or simply

arr.shift(1)

You need to specify the number of rows which should be deleted. In your case (and I assume that you only want to keep one) this can be done like this:

DELETE FROM your_table WHERE id_users=1 AND id_product=2
LIMIT (SELECT COUNT(*)-1 FROM your_table WHERE id_users=1 AND id_product=2)

It is correct that there is no work-around for this aside from ditching the select element, but if you only need to show more items in your select list you can simply use the size attribute:

<select multiple="multiple" size="15">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
</select>

Doing this you'll have additional empty lines if your collection of items lenght is smaller than size value.

You need to keep an array of the google.maps.Marker objects to hide (or remove or run other operations on them).

In the global scope:

var gmarkers = [];

Then push the markers on that array as you create them:

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i].latitude, locations[i].longitude),
    title: locations[i].title,
    icon: icon,
    map:map
});

// Push your newly created marker into the array:
gmarkers.push(marker);

Then to remove them:

function removeMarkers(){
    for(i=0; i<gmarkers.length; i++){
        gmarkers[i].setMap(null);
    }
}

working example (toggles the markers)

Return string from function

#include <stdio.h>

const char* greet() {
  return "Hello";
}

int main(void) {
  printf("%s", greet());
}

I would also try it this way

1) Create the Java Beans from the JSON schema

2) Use JSON parser libraries to avoid any sort of exception

3) Cast the parse result to the Java object that was created from the initial JSON schema.

Below is an example JSON Schema"

  "USD" : {"15m" : 478.68, "last" : 478.68, "buy" : 478.55, "sell" : 478.68,  "symbol" : "$"},
  "JPY" : {"15m" : 51033.99, "last" : 51033.99, "buy" : 51020.13, "sell" : 51033.99,  "symbol" : "¥"},

}

Output from the main method is:

ClassPojo [15m = 478.68, symbol = $, last = 478.68, sell = 478.68, buy = 478.55]

Sell Price : $478.68

Buy Price : $478.55

Hope this helps.

You can use SQL Compact Query Analyzer

http://sqlcequery.codeplex.com/

SQL Compact Query Analyzer is really snappy. 3 MB download, requires an install but really snappy and works.

Here is a one-liner that will uppercase the first letter and leave the case of all subsequent letters:

import re

key = 'wordsWithOtherUppercaseLetters'
key = re.sub('([a-zA-Z])', lambda x: x.groups()[0].upper(), key, 1)
print key

This will result in WordsWithOtherUppercaseLetters

None of the proposed answers works for surrogate pairs used to encode characters outside of the Unicode Basic Multiligual Plane.

Here is an example using three different techniques to iterate over the "characters" of a string (incl. using Java 8 stream API). Please notice this example includes characters of the Unicode Supplementary Multilingual Plane (SMP). You need a proper font to display this example and the result correctly.

// String containing characters of the Unicode 
// Supplementary Multilingual Plane (SMP)
// In that particular case, hieroglyphs.
String str = "The quick brown  jumps over the lazy ";

Iterate of chars

The first solution is a simple loop over all char of the string:

/* 1 */
System.out.println(
        "\n\nUsing char iterator (do not work for surrogate pairs !)");
for (int pos = 0; pos < str.length(); ++pos) {
    char c = str.charAt(pos);
    System.out.printf("%s ", Character.toString(c));
    //                       ^^^^^^^^^^^^^^^^^^^^^
    //                   Convert to String as per OP request
}

Iterate of code points

The second solution uses an explicit loop too, but accessing individual code points with codePointAt and incrementing the loop index accordingly to charCount:

/* 2 */
System.out.println(
        "\n\nUsing Java 1.5 codePointAt(works as expected)");
for (int pos = 0; pos < str.length();) {
    int cp = str.codePointAt(pos);

    char    chars[] = Character.toChars(cp);
    //                ^^^^^^^^^^^^^^^^^^^^^
    //               Convert to a `char[]`
    //               as code points outside the Unicode BMP
    //               will map to more than one Java `char`
    System.out.printf("%s ", new String(chars));
    //                       ^^^^^^^^^^^^^^^^^
    //               Convert to String as per OP request

    pos += Character.charCount(cp);
    //     ^^^^^^^^^^^^^^^^^^^^^^^
    //    Increment pos by 1 of more depending
    //    the number of Java `char` required to
    //    encode that particular codepoint.
}

Iterate over code points using the Stream API

The third solution is basically the same as the second, but using the Java 8 Stream API:

/* 3 */
System.out.println(
        "\n\nUsing Java 8 stream (works as expected)");
str.codePoints().forEach(
    cp -> {
        char    chars[] = Character.toChars(cp);
        //                ^^^^^^^^^^^^^^^^^^^^^
        //               Convert to a `char[]`
        //               as code points outside the Unicode BMP
        //               will map to more than one Java `char`
        System.out.printf("%s ", new String(chars));
        //                       ^^^^^^^^^^^^^^^^^
        //               Convert to String as per OP request
    });

Results

When you run that test program, you obtain:

Using char iterator (do not work for surrogate pairs !)
T h e   q u i c k   b r o w n   ? ?   j u m p s   o v e r   t h e   l a z y   ? ? ? ? ? ? ? ? 

Using Java 1.5 codePointAt(works as expected)
T h e   q u i c k   b r o w n      j u m p s   o v e r   t h e   l a z y       

Using Java 8 stream (works as expected)
T h e   q u i c k   b r o w n      j u m p s   o v e r   t h e   l a z y       

As you can see (if you're able to display hieroglyphs properly), the first solution does not handle properly characters outside of the Unicode BMP. On the other hand, the other two solutions deal well with surrogate pairs.

I'm going to push my pet peeve: the USING keyword.

If both tables on both sides of the JOIN have their foreign keys properly named (ie, same name, not just "id) then this can be used:

SELECT ...
FROM customers JOIN orders USING (customer_id)

I find this very practical, readable, and not used often enough.

try this:

double d= Double.parseDouble(yourString);

git diff path/file.css | grep -E "^\+" | grep -v '+++ b/' | cut -c 2-

• grep -E "^\+" is from previous accepted answer, it is incomplete because leaves non-source stuff
• grep -v '+++ b' removes non-source line with file name of later version
• cut -c 2- removes column of + signs, also may use sed 's/^\+//'

comm or sdiff were not an option because of git.

You can use find() :

$('#my_id').find('my_class');

Or maybe:

$('#my_id').find('span');

Both methods will word for what you want

Try with

c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -iru

When multiple versions of the .NET Framework are executing side-by-side on a single computer, the ASP.NET ISAPI version mapped to an ASP.NET application determines which version of the common language runtime (CLR) is used for the application.

Above command will Installs the version of ASP.NET that is associated with Aspnet_regiis.exe and only registers ASP.NET in IIS.

  m='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/';
  s.split('').forEach(function (v) {
    b=(b<<6)+m.indexOf(v); l+=6;
    if (l>=8) r+=String.fromCharCode((b>>>(l-=8))&0xff);
  });
  return r;
}

What I was actually after was an asynchronous implementation and to my surprise it turns out forEach as opposed to JQuery's $([]).each method implementation is very much synchronous.

If you also had such crazy notions in mind a 0 delay window.setTimeout will run the base64 decode asynchronously and execute the callback function with the result when done.

function decode_base64_async(s, cb) {
  setTimeout(function () { cb(decode_base64(s)); }, 0);
}

@Toothbrush suggested "index a string like an array", and get rid of the split. This routine seems really odd and not sure how compatible it will be, but it does hit another birdie so lets have it.

function decode_base64(s) {
  var b=l=0, r='',
  m='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/';
  [].forEach.call(s, function (v) {
    b=(b<<6)+m.indexOf(v); l+=6;
    if (l>=8) r+=String.fromCharCode((b>>>(l-=8))&0xff);
  });
  return r;
}

While trying to find more information on JavaScript string as array I stumbled on this pro tip using a /./g regex to step through a string. This reduces the code size even more by replacing the string in place and eliminating the need of keeping a return variable.

function decode_base64(s) {
  var b=l=0,
  m='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/';
  return s.replace(/./g, function (v) {
    b=(b<<6)+m.indexOf(v); l+=6;
    return l<8?'':String.fromCharCode((b>>>(l-=8))&0xff);
  });
}

If however you were looking for something a little more traditional perhaps the following is more to your taste.

function decode_base64(s) {
  var b=l=0, r='', s=s.split(''), i,
  m='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/';
  for (i in s) {
    b=(b<<6)+m.indexOf(s[i]); l+=6;
    if (l>=8) r+=String.fromCharCode((b>>>(l-=8))&0xff);
  }
  return r;
}

I didn't have the trailing null issue so this was removed to remain under par but it should easily be resolved with a trim() or a trimRight() if you'd prefer, should this pose a problem for you.

ie.

return r.trimRight();

Note:

The result is an ascii byte string, if you need unicode the easiest is to escape the byte string which can then be decoded with decodeURIComponent to produce the unicode string.

function decode_base64_usc(s) {      
  return decodeURIComponent(escape(decode_base64(s)));
}

Since escape is being deprecated we could change our function to support unicode directly without the need for escape or String.fromCharCode we can produce a % escaped string ready for URI decoding.

function decode_base64(s) {
  var b=l=0,
  m='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/';
  return decodeURIComponent(s.replace(/./g, function (v) {
    b=(b<<6)+m.indexOf(v); l+=6;
    return l<8?'':'%'+(0x100+((b>>>(l-=8))&0xff)).toString(16).slice(-2);
  }));
}

I had a similar issues fresh install and same error surprising. Finally I figured out it was a problem with browser cookies...

1. Try cleaning your browser cookies and see it helps to resolve this issue, before even trying any configuration changes.

2. Try using XAMPP Control panel "Admin" button instead of usual http://localhost or http://localhost/phpmyadmin

3. Try direct link: http://localhost/phpmyadmin/main.php or http://127.0.0.1/phpmyadmin/main.php

4. Finally try this: http://localhost/phpmyadmin/index.php?db=phpmyadmin&server=1&target=db_structure.php

Somehow if you have old installation and you upgraded to new version it keeps track of your old settings through cookies.

If this solution helped let me know.

One needs to be somewhat careful, since the Windows batch command:

for /f "delims=" %%a in ('command') do @set theValue=%%a

does not have the same semantics as the Unix shell statement:

theValue=`command`

Consider the case where the command fails, causing an error.

In the Unix shell version, the assignment to "theValue" still occurs, any previous value being replaced with an empty value.

In the Windows batch version, it's the "for" command which handles the error, and the "do" clause is never reached -- so any previous value of "theValue" will be retained.

To get more Unix-like semantics in Windows batch script, you must ensure that assignment takes place:

set theValue=
for /f "delims=" %%a in ('command') do @set theValue=%%a

Failing to clear the variable's value when converting a Unix script to Windows batch can be a cause of subtle errors.

If you added all the jars from bouncycastle.org (in my case from crypto-159.zip), just remove the ones for the JDKs that do not apply to you. There are redundancies. You probably only need the "jdk15on" jars.

I know this is old, but Google sent me here so I guess others will come too like me.

You could wrapping the transaction over try..catch or even reverse them, here my example code I used to in laravel 5,, if you look deep inside DB:transaction() in Illuminate\Database\Connection that the same like you write manual transaction.

Laravel Transaction

public function transaction(Closure $callback)
    {
        $this->beginTransaction();

        try {
            $result = $callback($this);

            $this->commit();
        }

        catch (Exception $e) {
            $this->rollBack();

            throw $e;
        } catch (Throwable $e) {
            $this->rollBack();

            throw $e;
        }

        return $result;
    }

so you could write your code like this, and handle your exception like throw message back into your form via flash or redirect to another page. REMEMBER return inside closure is returned in transaction() so if you return redirect()->back() it won't redirect immediately, because the it returned at variable which handle the transaction.

Wrap Transaction

$result = DB::transaction(function () use ($request, $message) {
   try{

      // execute query 1
      // execute query 2
      // ..

      return redirect(route('account.article'));

   } catch (\Exception $e) {
       return redirect()->back()->withErrors(['error' => $e->getMessage()]);
    }
 });

// redirect the page
return $result;

then the alternative is throw boolean variable and handle redirect outside transaction function or if your need to retrieve why transaction failed you can get it from $e->getMessage() inside catch(Exception $e){...}

You can group your specific layout under the correct folder structure as follows.

layout-land-target_version

ie

layout-land-19 // target KitKat

likewise you can create your layouts.

I guess you need a dynamic title that is why you don't set it in IB.

And I presume your viewController object is the one specified in the NIB?

Perhaps trying setting it to a dummy value in IB and then debug the methods to see which controller has the dummy value - assuming it appears as the title...

The below code worked fine:

Run Keyword if    '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2'    LOG    HELLO

I would like to hint on q2o. It is a JPA based Java object mapper which helps with many of the tedious SQL and JDBC ResultSet related tasks, but without all the complexity an ORM framework comes with. With its help mapping a ResultSet to an object is as easy as this:

while(rs.next()) {
    users.add(Q2Obj.fromResultSet(rs, User.class));
}

More about q2o can be found here.

Introduction

It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.

@Request/View/Flow/Session/ApplicationScoped

A @RequestScoped bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null/void without any navigation/redirect. A @FlowScoped bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped bean lives as long as the established HTTP session. An @ApplicationScoped bean lives as long as the web application runs. Note that the CDI @Model is basically a stereotype for @Named @RequestScoped, so same rules apply.

Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped for simple and non-ajax forms/presentations. Use @ViewScoped for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.

Abusing an @ApplicationScoped bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped bean for request, session or application scoped data, and abusing a @SessionScoped bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.

Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty in case of JSF managed beans or @Inject in case of CDI managed beans.

• Difference between View and Request scope in managed beans
• Advantages of using JSF Faces Flow instead of the normal navigation system
• Communication in JSF2 - Managed bean scopes

@CustomScoped/NoneScoped/Dependent

It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped and @NoneScoped, which are rarely used in real world. The @CustomScoped must refer a custom Map<K, Bean> implementation in some broader scope which has overridden Map#put() and/or Map#get() in order to have more fine grained control over bean creation and/or destroy.

The JSF @NoneScoped and CDI @Dependent basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped or @Dependent is injected in a @SessionScoped, then it will live as long as the @SessionScoped bean.

• Expire specific managed bean instance after time interval
• what is none scope bean and when to use it?
• What is the default Managed Bean Scope in a JSF 2 application?

Flash scope

As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.

This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped. The flash scope is only available as a map via ExternalContext#getFlash() in managed beans and #{flash} in EL.

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.

To position an element, a <table> in your case you want to use either padding or margins.

the difference between margins and paddings can be seen as the "box model":

Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.

I highly recommend the article above if you need to learn how to use CSS.

To move the table down and right I would use margins like so:

table{
    margin:25px 0 0 25px;
}

This is in shorthand so the margins are as follows:

margin: top right bottom left;

// array of $ids that you need to select
$ids = array('1', '2', '3', '4', '5', '6', '7', '8');

// create sql part for IN condition by imploding comma after each id
$in = '(' . implode(',', $ids) .')';

// create sql
$sql = 'SELECT * FROM products WHERE catid IN ' . $in;

// see what you get
var_dump($sql);

Update: (a short version and update missing comma)

$ids = array('1','2','3','4');
$sql = 'SELECT * FROM products WHERE catid IN (' . implode(',', $ids) . ')';

I think because it's Standard's ver.

I don't know if you write your code in VS. But if you did, just go to ARCHITECTURE - new Diagram. & choose yours, & the VS 'll take the care of the rest :)

I have a large app that was having problems uploading to the AppStore using the archive method you will find in XCode 4. The activity indicator kept spinning for hours whether I was trying to validate or distribute, so I created a support ticket to Apple. During that process, I found out you could right click on the .app in your Products folder inside the Project Navigator of XCode, and compress the app to submit using the Application Loader 2.5.1. (aka the old method). Only the Debug - iphoneos folder is accessible this way (for now) and once Apple responded, this is what they had to say:

I'm glad to hear that Application Loader has provided you a viable workaround. Discussing this situation internally, we're not sure that submitting the Debug build will pose too much of a problem (so long as it was signed with the App Store distribution profile, as you mentioned it was). The app will likely be slower as the debug switches are turned on and optimizations are turned off for the Debug configuration, though it will still run. App Review will ultimately determine whether or not that's ok, as I'm not sure that's something they check for. You could try reaching out directly to App Review to confirm this, if you wish. However, since App Loader is working for you, I do recommend rebuilding the app with your Release configuration and resubmitting to play it safe. To find your Release build in Xcode 4.x, control-click on the Application Archive on the Archives tab in the organizer, and choose "Show in Finder." Then, control-click on the .xcarchive file in Finder and choose "Show Package Contents." The release built .app file should be located within the /Products/Applications folder.

This was very helpful information for developers who are having problems with the archive method, and my app is now uploading successfully without any concern that it won't run to the best of it's ability.

The following solution worked for me in Bootstrap 3.3.4:

CSS:

/*no collapse*/

.navbar-collapse.collapse.off {
    display: block!important;
}
.navbar-collapse.collapse.off ul {
    margin: 0;
    padding: 0;
}

.navbar-nav.no-collapse>li,
.navbar-nav.no-collapse {
    float: left !important;
}

.navbar-right.no-collapse {
    float: right!important;
}

then add the .no-collapse class to each of the lists and the .off class to the main container. Here is an example written in jade:

nav.navbar.navbar-default.navbar-fixed-top
        .container-fluid
            .collapse.navbar-collapse.off
                ul.nav.navbar-nav.no-collapse
                    li
                        a(href='#' class='glyph')
                            i(class='glyphicon glyphicon-info-sign')
                ul.nav.navbar-nav.navbar-right.no-collapse
                    li.dropdown
                        a.dropdown-toggle(href='#', data-toggle='dropdown' role='button' aria-expanded='false')
                            | Tools
                            span.caret
                        ul.dropdown-menu(role='menu')
                            li
                                a(href='#') Tool #1
                    li
                        a(href='#')
                            | Logout

That is a pretty standard use case for apply():

R> vec <- 1:10
R> DF <- data.frame(start=c(1,3,5,7), end=c(2,6,7,9))
R> DF$newcol <- apply(DF,1,function(row) mean(vec[ row[1] : row[2] ] ))
R> DF
  start end newcol
1     1   2    1.5
2     3   6    4.5
3     5   7    6.0
4     7   9    8.0
R> 

You can also use plyr if you prefer but here is no real need to go beyond functions from base R.

I had this on a form where the Recordsource is dynamic.

The Sql was fine, answer is to trap the error!

Private Sub Form_Error(DataErr As Integer, Response As Integer)
'    Debug.Print DataErr

    If DataErr = 3075 Then
        Response = acDataErrContinue
    End If

End Sub

What I would do:

char c;
int cint;
for(int n = 0; n < str.length(); n ++;)
{
    c = str.charAt(n);
    cint = (int)c;
    if(cint <48 || (cint > 57 && cint < 65) || (cint > 90 && cint < 97) || cint > 122)
    {
        specialCharacterCount++
    }
}

That is a simple way to do things, without having to import any special classes. Stick it in a method, or put it straight into the main code.

ASCII chart: http://www.gophoto.it/view.php?i=http://i.msdn.microsoft.com/dynimg/IC102418.gif#.UHsqxFEmG08

Try this: getActivity().runOnUiThread(new Runnable...

It's because:

1) the implicit this in your call to runOnUiThread is referring to AsyncTask, not your fragment.

2) Fragment doesn't have runOnUiThread.

However, Activity does.

Note that Activity just executes the Runnable if you're already on the main thread, otherwise it uses a Handler. You can implement a Handler in your fragment if you don't want to worry about the context of this, it's actually very easy:

// A class instance
private Handler mHandler = new Handler(Looper.getMainLooper());

// anywhere else in your code
mHandler.post(<your runnable>);
// ^ this will always be run on the next run loop on the main thread.

EDIT: @rciovati is right, you are in onPostExecute, that's already on the main thread.

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

A simple for loop?

for i in range(3):
  do()

Or, if you're interested in the results and want to collect them, with the bonus of being a 1 liner:

vals = [do() for _ in range(3)]

Turn on Password Authentication

By default, you need to use keys to ssh into your google compute engine machine, but you can turn on password authentication if you do not need that level of security.

Tip: Use the Open in browser window SSH option from your cloud console to gain access to the machine. Then switch to the root user with sudo su - root to make the configuration changes below.

1. Edit the /etc/ssh/sshd_config file.
2. Change PasswordAuthentication and ChallengeResponseAuthentication to yes.
3. Restart ssh /etc/init.d/ssh restart.

String x = "stackoverflow";
String [] y = x.split("");

it clears the all the bits that are not in the first byte

You haven't specified what kind of html element you are trying to do an absolute xpath search on. In your case, it's the input element.

Try this:

element = findElement(By.xpath("//input[@class='t-TextBox' and @type='email' and @test-    
id='test-username']");

Methods and variables that are not declared as static are known as instance methods and instance variables. To refer to instance methods and variables, you must instantiate the class first means you should create an object of that class first.For static you don't need to instantiate the class u can access the methods and variables with the class name using period sign which is in (.)

for example:

Person.staticMethod();           //accessing static method.

for non-static method you must instantiate the class.

Person person1 = new Person();   //instantiating
person1.nonStaticMethod();       //accessing non-static method.

The proper way to do this is to use dispatch_async in the main_queue, as I did in the following code

dispatch_async(dispatch_get_main_queue(), {
    (self.delegate as TBGQRCodeViewController).displayQRCode(receiveAddr, withAmountInBTC:amountBTC)
})

One more directive

html

<btn-file-selector/>

code

.directive('btnFileSelector',[function(){
  return {
    restrict: 'AE', 
    template: '<div></div>', 
    link: function(s,e,a){

      var el = angular.element(e);
      var button = angular.element('<button type="button" class="btn btn-default btn-upload">Add File</button>'); 
      var fileForm = angular.element('<input type="file" style="display:none;"/>'); 

      fileForm.on('change', function(){
         // Actions after the file is selected
         console.log( fileForm[0].files[0].name );
      });

      button.bind('click',function(){
        fileForm.click();
      });     


     el.append(fileForm);
     el.append(button);
    }
  }  
}]); 

This may be a overwhelming problem if you use Auto layout because you can not directly manipulate frames anymore. There is a simple solution without too much work.

I ended up writing an utility method in an Utility Class and called it from all the view controllers's viewDidLayoutSubviews Method.

+ (void)addStatusBarIfiOS7:(UIViewController *)vc
    {
        if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) {
            CGRect viewFrame = vc.view.frame;
            if(viewFrame.origin.y == 20) {
                //If the view's y origin is already 20 then don't move it down.
                return;
            }
            viewFrame.origin.y+=20.0;
            viewFrame.size.height-= 20.0;
            vc.view.frame = viewFrame;
            [vc.view layoutIfNeeded];
        }
    }

Override your viewDidLayoutSubviews method in the view controller, where you want status bar. It will get you through the burden of Autolayout.

- (void)viewDidLayoutSubviews
{
    [[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
    [super viewDidLayoutSubviews];
    [MyUtilityClass addStatusBarIfiOS7:self];
}

I was facing following error with code (nodejs 0.10.13), provided by ampersand:

origin is not allowed by access-control-allow-origin

Issue was resolved changing

response.writeHead(200, {"Content-Type": "text/plain"});

to

response.writeHead(200, {
                 'Content-Type': 'text/html',
                 'Access-Control-Allow-Origin' : '*'});

Not for the questioner, but for all others, which are interested: See: How to define Typescript Map of key value pair. where key is a number and value is an array of objects

The solution is therefore:

let yourVar: Map<YourKeyType, YourValueType>;
// now you can use it:
yourVar = new Map<YourKeyType, YourValueType>();
yourVar[YourKeyType] = <YourValueType> yourValue;

Cheers!

Seems to me like you are updating the value of the text field in javascript. onchange event will be triggered only when you key-in data and tab out of the text field.

One workaround is to trigger the textbox change event when modifying the textbox value from the script. See below,

$("#kat").change(function(){ 
    alert("Hello");
});


$('<tab_cell>').click (function () {
   $('#kat')
      .val($(this).text()) //updating the value of the textbox 
      .change();           //trigger change event.
});

response.session.access_token doesn't work in my code. But this works: response.authResponse.accessToken

     FB.login(function(response) { alert(response.authResponse.accessToken);
     }, {perms:'read_stream,publish_stream,offline_access'});

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

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

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

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

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

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

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

int n = 5;
fibTopDown(n);

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

By specifying the @JoinColumn on both models you don't have a two way relationship. You have two one way relationships, and a very confusing mapping of it at that. You're telling both models that they "own" the IDAIRLINE column. Really only one of them actually should! The 'normal' thing is to take the @JoinColumn off of the @OneToMany side entirely, and instead add mappedBy to the @OneToMany.

@OneToMany(cascade = CascadeType.ALL, mappedBy="airline")
public Set<AirlineFlight> getAirlineFlights() {
    return airlineFlights;
}

That tells Hibernate "Go look over on the bean property named 'airline' on the thing I have a collection of to find the configuration."

Some more explanations to the solution Rachel already gave:

"WPF Apps With The Model-View-ViewModel Design Pattern"

by Josh Smith

http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

static class Extensions
{
    public static T[] Concat<T>(this T[] array1, params T[] array2) => ConcatArray(array1, array2);

    public static T[] ConcatArray<T>(params T[][] arrays)
    {
        int l, i;

        for (l = i = 0; i < arrays.Length; l += arrays[i].Length, i++);

        var a = new T[l];

        for (l = i = 0; i < arrays.Length; l += arrays[i].Length, i++)
            arrays[i].CopyTo(a, l);

        return a;
    }
}

I think the above solution is more general & lighter than the others I saw here. It is more general because it doesn't limit concatenation for only two arrays and is lighter because it doesn't use LINQ nor List.

Note the solution is concise and the added generality doesn't add significant runtime overhead.

go to the side project panel, right click on references -> add reference and find System.Windows.Forms

Any time some error like this occurs (some namespace you added is missing that is obviously there) the solution is probably this - adding a reference.

This is needed because your default project does not include everything because you probably wont need it so it saves space. A good practice is to exclude things you're not using.

Access from Windows by Git Bash console:

scp root@ip:/etc/../your-file "C:/Users/XXX/Download"

As another guy described here, all you need to do is add

height: 100vh;

to the style of whatever you need to fill the screen

The only problem with cnoremap w!! is that it replaces w with ! (and hangs until you type the next char) whenever you type w! at the : command prompt. Like when you want to actually force-save with w!. Also, even if it's not the first thing after :.

Therefore I would suggest mapping it to something like <Fn>w. I personally have mapleader = F1, so I'm using <Leader>w.

Filter using wildcards:

Get-ChildItem -Filter CopyForBuild* -Include *.bat,*.cmd -Exclude *.old.cmd,*.old.bat -Recurse

Filtering using a regular expression:

Get-ChildItem -Path "V:\Myfolder" -Recurse
| Where-Object { $_.Name -match '\ACopyForBuild\.[(bat)|(cmd)]\Z' }

An Alternative Solution to the above

Card(
  shape: RoundedRectangleBorder(
     borderRadius: BorderRadius.only(topLeft: Radius.circular(20), topRight: Radius.circular(20))),
  color: Colors.white,
  child: ...
)

You can use BorderRadius.only() to customize the corners you wish to manage.

In my opinion you should delete this AVD and create new one for API-7. It will work fine if not please let me know I'll send you some more solution.

Regards,

var d = $('.text_div');
d.text(d.text().trim().replace(/contains/i, "hello everyone"));

This works for me:

convert original.png -fuzz 10% -transparent white transparent.png

where the smaller the fuzz %, the closer to true white or conversely, the larger the %, the more variation from white is allowed to become transparent

You should be using datetime.datetime.strptime. Note that very old versions of Python (2.4 and older) don't have datetime.datetime.strptime; use time.strptime in that case.

I tried everything above. The credit goes to all of the responses above. Having tried all of the suggestions on their own, I just assembled this combination of suggestions in an order that made sense to me. Note my Documents folder is on a shared drive. The subst/IISExpress stuff is not applicable unless you're in the same boat.

• Configure VS to run as admin
• Uninstall IIS via Add/Remove Programs, Windows Features
• Reboot
• Run WinRAR or something similar as admin and archive C:\windows\system32\inetsrv\
• Run cmd as admin and rmdir /s c:\windows\system32\inetsrv\ to completely remove all traces of the last install. Leave elevated cmd prompt open for later.
• Reinstall IIS with IIS 6 Metabase compatibility (doubt this was necessary)
• Leave Default AppPool and Default Website as-is (I had previously deleted both)
• Ran C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ga MYDOMAIN\scottt732
• Ran C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

Also, because my Documents folder is on a share drive, I was having IIS Express issues. I don't use/like IIS Express, but Visual Studio complained about it.

• From elevated cmd prompt, ran subst U: c:\Temp. Created C:\Temp\Documents\ and copied the IISExpress folder from my U drive.
• Created CustomUserHome key in HKCU\Software\Microsoft\IISExpress with C:\Temp\Documents\IISExpress
• This allowed me to get Visual Studio to open my web projects and edit the properties. I tweaked the projects to store web server settings in a user file and adjusted it to use a Custom URL (not sure if this was necessary)
• I may/may not have to run the subst command each time I restart. Don't care.

And after throwing in the towel 3 times and spending roughly ~6 hours I can open web projects in Visual Studio (2015 Update 2).

IMPORTANT UPDATE: ng2-bootstrap is now replaced by ngx-bootstrap

ngx-bootstrap supports both Angular 3 and 4.

Update : 1.0.0-beta.11-webpack or above versions

First of all check your angular-cli version with the following command in the terminal:

ng -v

If your angular-cli version is greater than 1.0.0-beta.11-webpack, then you should follow these steps:

1. Install ngx-bootstrap and bootstrap:

   npm install ngx-bootstrap bootstrap --save
   

This line installs Bootstrap 3 nowadays, but can install Bootstrap 4 in the future. Keep in mind ngx-bootstrap supports both versions.

2. Open src/app/app.module.ts and add:

   import { AlertModule } from 'ngx-bootstrap';
   ...
   @NgModule({
   ...
   imports: [AlertModule.forRoot(), ... ],
   ... 
   })
   

3. Open angular-cli.json (for angular6 and later file name changed to angular.json ) and insert a new entry into the styles array:

   "styles": [
   "styles.css",
   "../node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],
   

4. Open src/app/app.component.html and add:

   <alert type="success">hello</alert>
   

1.0.0-beta.10 or below versions:

And, if your angular-cli version is 1.0.0-beta.10 or below, then you can use below steps.

First, go to the project directory and type:

npm install ngx-bootstrap --save

Then, open your angular-cli-build.js and add this line:

vendorNpmFiles: [
   ...
   'ngx-bootstrap/**/*.js',
   ...
]

Now, open your src/system-config.ts then write:

const map:any = {
   ...
   'ngx-bootstrap': 'vendor/ngx-bootstrap',
   ...
}

...and:

const packages: any = {
  'ngx-bootstrap': {
    format: 'cjs',
    defaultExtension: 'js',
    main: 'ngx-bootstrap.js'
  }
};

Since pandas 1.0.0 df.sort_values has a new parameter ignore_index which does exactly what you need:

In [1]: df2 = df.sort_values(by=['x','y'],ignore_index=True)

In [2]: df2
Out[2]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#hideshow').click(function(){
    $('#content').toggle('show');
  });
});
</script>

And the html

<div id='content'>Hello World</div>
<input type='button' id='hideshow' value='hide/show'>

Mustache templates are, by design, very simple; the homepage even says:

Logic-less templates.

So the general approach is to do your logic in JavaScript and set a bunch of flags:

if(notified_type == "Friendship")
    data.type_friendship = true;
else if(notified_type == "Other" && action == "invite")
    data.type_other_invite = true;
//...

and then in your template:

{{#type_friendship}}
    friendship...
{{/type_friendship}}
{{#type_other_invite}}
    invite...
{{/type_other_invite}}

If you want some more advanced functionality but want to maintain most of Mustache's simplicity, you could look at Handlebars:

Handlebars provides the power necessary to let you build semantic templates effectively with no frustration.

Mustache templates are compatible with Handlebars, so you can take a Mustache template, import it into Handlebars, and start taking advantage of the extra Handlebars features.

Here's what helped this beginning Android programmer (former professional programmer, years ago) in speeding up Android Studio 2.2. I know this is a rehash, but, just summarizing in one place.

Initial builds can still be brutally slow, but restarts of running apps are now usually very tolerable. I'm using a sub-optimal PC: AMD Quad-Core A8-7410 CPU, 8MB RAM, non-SSD HD, Win 10. (And, this is my first Stack Overflow posting.... ;)

IN SETTINGS -> GRADLE:

yes for "Offline work" (this is perhaps the most import setting).

IN SETTINGS -> COMPILER:

yes for "Compile independent modules in parallel" (not sure if this does in fact help utilize multicore CPUs).

IN GRADLE SCRIPTS, "build.gradle (Module: app)":

defaultConfig {
    ...
   // keep min high so that restarted apps can be hotswapped...obviously, this is hugely faster.
   minSdkVersion 14
   ...
    // enabling multidex support...does make big difference for me.
    multiDexEnabled true

ALSO IN GRADLE SCRIPTS, "gradle.properties (Project Properties)":

org.gradle.jvmargs=-Xmx3048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

org.gradle.parallel=true org.gradle.daemon=true

Additionally, testing on a physical device instead of the emulator is working well for me; a small tablet that stands up is convenient.

That's the fastest solution today (17-3-2018):

Close all Chrome tabs / windows and run on your command line this: (or add it as a shortcode)

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --ignore-certificate-errors

Is this what you mean?

SELECT DISTINCT C.valueC
FROM 
C
INNER JOIN B ON C.id = B.lookupC
INNER JOIN A ON B.id = A.lookupB

I used a ListView with Glide image loader, having memory growth. Then I replaced the ListView with a RecyclerView. It is not only more difficult in coding, but also leads to a more memory usage than a ListView. At least, in my project.

In another activity I used a complex list with EditText's. In some of them an input method may vary, also a TextWatcher can be applied. If I used a ViewHolder, how could I replace a TextWatcher during scrolling? So, I used a ListView without a ViewHolder, and it works.

Setup JAVA_OPTS as a system variable with the following content:

JAVA_OPTS="-Xms256m -Xmx512m"

After that in a command prompt run the following commands:

SET JAVA_OPTS="-Xms256m -Xmx512m"

This can be explained as follows:

• allocate at minimum 256MBs of heap
• allocate at maximum 512MBs of heap

These values should be changed according to application requirements.

EDIT:

You can also try adding it through the Environment Properties menu which can be found at:

1. From the Desktop, right-click My Computer and click Properties.
2. Click Advanced System Settings link in the left column.
3. In the System Properties window click the Environment Variables button.
4. Click New to add a new variable name and value.
5. For variable name enter JAVA_OPTS for variable value enter -Xms256m -Xmx512m
6. Click ok and close the System Properties Tab.
7. Restart any java applications.

EDIT 2:

JAVA_OPTS is a system variable that stores various settings/configurations for your local Java Virtual Machine. By having JAVA_OPTS set as a system variable all applications running on top of the JVM will take their settings from this parameter.

To setup a system variable you have to complete the steps listed above from 1 to 4.

None of these answers worked for me. I had to use the command line:

mysql -u root db_name < db_dump.sql
SET NAMES 'utf8';
SOURCE db_dump.sql;

Done!

There is a style that I've created based on dark style from VS 2015 to use on my VS 2010. You can download this style from Dark Style from VS 2015.

After download it, just import through menu Tools -> Import and Export Settings...

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.

Well, since you are using Python, you can just open a file and keep reading lines from it.

f = open('file.log')

If the line read is not empty, you process it.

line = f.readline()
if line:
    // Do what you want with the line

You may be missing that it is ok to keep calling readline at the EOF. It will just keep returning an empty string in this case. And when something is appended to the log file, the reading will continue from where it stopped, as you need.

If you are looking for a solution that uses events, or a particular library, please specify this in your question. Otherwise, I think this solution is just fine.

I have recently ran across similar situation. To debug in any VS IDE version, open exceptions from Debug (Ctrl + D, E) - check all checkboxes against the column "Thrown", and run the application in debug mode. I have realized that one of the tables was not imported properly in the new database, so internal Sql Exception was killing the connection, thus results into this error.

Gist of the story is, If Previously working code returns this error on a new database, this could be database schema missing issue, realize by above debugging tip,

Hope It Helps, HydTechie

Maybe .value_counts()?

>>> import pandas
>>> my_series = pandas.Series([1,2,2,3,3,3, "fred", 1.8, 1.8])
>>> my_series
0       1
1       2
2       2
3       3
4       3
5       3
6    fred
7     1.8
8     1.8
>>> counts = my_series.value_counts()
>>> counts
3       3
2       2
1.8     2
fred    1
1       1
>>> len(counts)
5
>>> sum(counts)
9
>>> counts["fred"]
1
>>> dict(counts)
{1.8: 2, 2: 2, 3: 3, 1: 1, 'fred': 1}

I solved this problem with custom annotations. This is my "SkipSerialisation" Annotation class:

@Target (ElementType.FIELD)
public @interface SkipSerialisation {

}

and this is my GsonBuilder:

gsonBuilder.addSerializationExclusionStrategy(new ExclusionStrategy() {

  @Override public boolean shouldSkipField (FieldAttributes f) {

    return f.getAnnotation(SkipSerialisation.class) != null;

  }

  @Override public boolean shouldSkipClass (Class<?> clazz) {

    return false;
  }
});

Example :

public class User implements Serializable {

  public String firstName;

  public String lastName;

  @SkipSerialisation
  public String email;
}

Based on the answer of Mehrdad Afshari and the comment of Andrew Hanlon for a speedup, here is my take.

Important difference to the original task: A root node has ID==parentID.

class MyObject
{   // The actual object
    public int ParentID { get; set; }
    public int ID { get; set; }
}

class Node
{
    public List<Node> Children = new List<Node>();
    public Node Parent { get; set; }
    public MyObject Source { get; set; }
}

List<Node> BuildTreeAndGetRoots(List<MyObject> actualObjects)
{
    var lookup = new Dictionary<int, Node>();
    var rootNodes = new List<Node>();

    foreach (var item in actualObjects)
    {
        // add us to lookup
        Node ourNode;
        if (lookup.TryGetValue(item.ID, out ourNode))
        {   // was already found as a parent - register the actual object
            ourNode.Source = item;
        }
        else
        {
            ourNode = new Node() { Source = item };
            lookup.Add(item.ID, ourNode);
        }

        // hook into parent
        if (item.ParentID == item.ID)
        {   // is a root node
            rootNodes.Add(ourNode);
        }
        else
        {   // is a child row - so we have a parent
            Node parentNode;
            if (!lookup.TryGetValue(item.ParentID, out parentNode))
            {   // unknown parent, construct preliminary parent
                parentNode = new Node();
                lookup.Add(item.ParentID, parentNode);
            }
            parentNode.Children.Add(ourNode);
            ourNode.Parent = parentNode;
        }
    }

    return rootNodes;
}

Same codes from Nickolay above, but tested on IE9 and chrome (and removed the extra rendering):

window.onload = window.onresize = function() {
   var canvas = document.getElementById('canvas');
   var viewportWidth = window.innerWidth;
   var viewportHeight = window.innerHeight;
   var canvasWidth = viewportWidth * 0.8;
   var canvasHeight = canvasWidth / 2;

   canvas.style.position = "absolute";
   canvas.setAttribute("width", canvasWidth);
   canvas.setAttribute("height", canvasHeight);
   canvas.style.top = (viewportHeight - canvasHeight) / 2 + "px";
   canvas.style.left = (viewportWidth - canvasWidth) / 2 + "px";
}

HTML:

<body>
  <canvas id="canvas" style="background: #ffffff">
     Canvas is not supported.
  </canvas>
</body>

The top and left offset only works when I add px.

If you are using Bootstrap 3 and Less you could apply the responsive tables to all resolutions by updatingthe file:

tables.less

or overwriting this part:

@media (max-width: @screen-xs) {
  .table-responsive {
    width: 100%;
    margin-bottom: 15px;
    overflow-y: hidden;
    overflow-x: scroll;
    border: 1px solid @table-border-color;

    // Tighten up spacing and give a background color
    > .table {
      margin-bottom: 0;
      background-color: #fff;

      // Ensure the content doesn't wrap
      > thead,
      > tbody,
      > tfoot {
        > tr {
          > th,
          > td {
            white-space: nowrap;
          }
        }
      }
    }

    // Special overrides for the bordered tables
    > .table-bordered {
      border: 0;

      // Nuke the appropriate borders so that the parent can handle them
      > thead,
      > tbody,
      > tfoot {
        > tr {
          > th:first-child,
          > td:first-child {
            border-left: 0;
          }
          > th:last-child,
          > td:last-child {
            border-right: 0;
          }
        }
        > tr:last-child {
          > th,
          > td {
            border-bottom: 0;
          }
        }
      }
    }
  }
}

With:

@media (max-width: @screen-lg) {
  .table-responsive {
    width: 100%;
...

Note how I changed the first line @screen-XX value.

I know making all tables responsive may not sound that good, but I found it extremely useful to have this enabled up to LG on large tables (lots of columns).

Hope it helps someone.

Create an app using Alamofire with Api Post method

Install pod file -pod 'Alamofire', '~> 4.0' for Swift 3 with Xcode 9

Create Webservices.swift class, import Alamofire

Design storyBoard ,Login View

What's the idiomatic syntax for prepending to a short python list?

You don't usually want to repetitively prepend to a list in Python.

If it's short, and you're not doing it a lot... then ok.

list.insert

The list.insert can be used this way.

list.insert(0, x)

But this is inefficient, because in Python, a list is an array of pointers, and Python must now take every pointer in the list and move it down by one to insert the pointer to your object in the first slot, so this is really only efficient for rather short lists, as you ask.

Here's a snippet from the CPython source where this is implemented - and as you can see, we start at the end of the array and move everything down by one for every insertion:

for (i = n; --i >= where; )
    items[i+1] = items[i];

If you want a container/list that's efficient at prepending elements, you want a linked list. Python has a doubly linked list, which can insert at the beginning and end quickly - it's called a deque.

deque.appendleft

A collections.deque has many of the methods of a list. list.sort is an exception, making deque definitively not entirely Liskov substitutable for list.

>>> set(dir(list)) - set(dir(deque))
{'sort'}

The deque also has an appendleft method (as well as popleft). The deque is a double-ended queue and a doubly-linked list - no matter the length, it always takes the same amount of time to preprend something. In big O notation, O(1) versus the O(n) time for lists. Here's the usage:

>>> import collections
>>> d = collections.deque('1234')
>>> d
deque(['1', '2', '3', '4'])
>>> d.appendleft('0')
>>> d
deque(['0', '1', '2', '3', '4'])

deque.extendleft

Also relevant is the deque's extendleft method, which iteratively prepends:

>>> from collections import deque
>>> d2 = deque('def')
>>> d2.extendleft('cba')
>>> d2
deque(['a', 'b', 'c', 'd', 'e', 'f'])

Note that each element will be prepended one at a time, thus effectively reversing their order.

Performance of list versus deque

First we setup with some iterative prepending:

import timeit
from collections import deque

def list_insert_0():
    l = []
    for i in range(20):
        l.insert(0, i)

def list_slice_insert():
    l = []
    for i in range(20):
        l[:0] = [i]      # semantically same as list.insert(0, i)

def list_add():
    l = []
    for i in range(20):
        l = [i] + l      # caveat: new list each time

def deque_appendleft():
    d = deque()
    for i in range(20):
        d.appendleft(i)  # semantically same as list.insert(0, i)

def deque_extendleft():
    d = deque()
    d.extendleft(range(20)) # semantically same as deque_appendleft above

and performance:

>>> min(timeit.repeat(list_insert_0))
2.8267281929729506
>>> min(timeit.repeat(list_slice_insert))
2.5210217320127413
>>> min(timeit.repeat(list_add))
2.0641671380144544
>>> min(timeit.repeat(deque_appendleft))
1.5863927800091915
>>> min(timeit.repeat(deque_extendleft))
0.5352169770048931

The deque is much faster. As the lists get longer, I would expect a deque to perform even better. If you can use deque's extendleft you'll probably get the best performance that way.

Just want to update, that in Spring 5, as mentioned in Spring docs, Spring supports 6 scopes, four of which are available only if you use a web-aware ApplicationContext.

singleton (Default) Scopes a single bean definition to a single object instance per Spring IoC container.

prototype Scopes a single bean definition to any number of object instances.

request Scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.

session Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.

application Scopes a single bean definition to the lifecycle of a ServletContext. Only valid in the context of a web-aware Spring ApplicationContext.

websocket Scopes a single bean definition to the lifecycle of a WebSocket. Only valid in the context of a web-aware Spring ApplicationContext.

This assumes that the column of potential date values is in column A. You could do something like this in an adjacent column:

Make a nested formula that converts the "date" to its numeric value if it's valid, or an error value to zero if it's not.
Then it converts the valid numeric values to 1's and leaves the zeroes as they are.
Then sum the new column to get the total number of valid dates.

=IF(IFERROR(DATEVALUE(A1),0)>0,1,0)

Python code:

import sys

# main
param_1= sys.argv[1] 
param_2= sys.argv[2] 
param_3= sys.argv[3]  
print 'Params=', param_1, param_2, param_3

Invocation:

$python myfile.py var1 var2 var3

Output:

Params= var1 var2 var3 

To add the privileges needed to the files add and grant right to the following local user: SQLServerMSSQLUser$COMPUTERNAME$INSTANCENAME, where COMPUTERNAME and INSTANCENAME has to be replaced with name of computer and MSSQL instance respectively.

The easiest way to get rid of the the ugly frame in newer versions of matplotlib:

import matplotlib.pyplot as plt
plt.box(False)

If you really must always use the object oriented approach, then do: ax.set_frame_on(False).

Use the @Url.Action method. This will work and determines the correct route regardless of what IIS server you deploy to.

Example- window.location.href="@Url.Action("Action", "Controller")";

so in the case of the Index action on the Home controller - window.location.href="@Url.Action("Index", "Home")";

The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, && and || only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{} construction and to direct program control rather than construct new vectors.. The & and the | operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.

When the arguments to && or || are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.

> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3

The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.

You can use Armory plugin which makes switching between projects comfortable. The default shortcut for Project List is Alt + A.

By default currently opened projects are displayed at the top of this list (with bold style).

To show the commits I have staged that are ready to push I do

git log remotes/trunk~4..HEAD --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s" --date=short | awk -F'\t' '{gsub(/[, ]/,"",$2);gsub(/HEAD/, "\033[1;36mH\033[00m",$2);gsub(/master/, "\033[1;32mm\033[00m",$2);gsub(/trunk/, "\033[1;31mt\033[00m",$2);print $1 "\t" gensub(/([\(\)])/, "\033[0;33m\\1\033[00m","g",$2) $3}' | less -eiFRXS

The output looks something like:

ef87da7 2013-01-17 haslers      (Hm)Fix NPE in Frobble
8f6d80f 2013-01-17 haslers      Refactor Frobble

a1db9ef 2013-01-17 haslers      Add Frobble Widget

Where the first column appears in yellow, and the 'H' 'm' and 't' in parentesis show the HEAD, master and trunk and appear in their usual "--decorate" colors

Here it is with line breaks so you can see what it's doing:

git log remotes/trunk~4..HEAD --date=short
    --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s"
    | awk -F'\t' '{
         gsub(/[, ]/,"",$2);
         gsub(/HEAD/, "\033[1;36mH\033[00m",$2);
         gsub(/master/, "\033[1;32mm\033[00m",$2);
         gsub(/trunk/, "\033[1;31mt\033[00m",$2);
         print $1 "\t" gensub(/([\(\)])/, "\033[0;33m\\1\033[00m","g",$2) $3}'

I have aliased to "staged" with:

git config alias.staged '!git log remotes/trunk~4..HEAD --date=short --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s" | awk -F"\t" "{gsub(/[, ]/,\"\",\$2);gsub(/HEAD/, \"\033[1;36mH\033[00m\",\$2);gsub(/master/, \"\033[1;32mm\033[00m\",\$2);gsub(/trunk/, \"\033[1;31mt\033[00m\",\$2);print \$1 \"\t\" gensub(/([\(\)])/, \"\033[0;33m\\\\\1\033[00m\",\"g\",\$2) \$3}"'

(Is there an easier way to escape that? it was a bit tricky to work out what needed escaping)

You could try this:

<input type="file" capture="camera" accept="image/*" id="cameraInput" name="cameraInput">

but it has to be iOS 6+ to work. That will give you a nice dialogue for you to choose either to take a picture or to upload one from your album i.e.

An example can be found here: Capturing camera/picture data without PhoneGap

Instead of gdb, run gdbtui. Or run gdb with the -tui switch. Or press C-x C-a after entering gdb. Now you're in GDB's TUI mode.

Enter layout asm to make the upper window display assembly -- this will automatically follow your instruction pointer, although you can also change frames or scroll around while debugging. Press C-x s to enter SingleKey mode, where run continue up down finish etc. are abbreviated to a single key, allowing you to walk through your program very quickly.

I had the same problem and error. In my case it was the https_proxy not set. Setting the https_proxy environment variable fixed the issue.

$ export https_proxy=https://<porxy_addres>:<proxy_port>

Example:

$ export https_proxy=https://my.proxy.company.com:8000

Hope this help somebody.

This will check if requested email exist in the user table:

if (User::where('email', $request->email)->exists()) {
   //email exists in user table
}

There is an unnecessary hashtag; change the code to this:

var e = document.getElementById("ticket_category_clone").value;

I can recommend make pre-init of future index value, this is very usefull in a lot of case like multi work, some export e.t.c.

just create additional User_Seq table: with two fields: id Uniq index and SeqVal nvarchar(1)

and create next SP, and generated ID value from this SP and put to new User row!

CREATE procedure [dbo].[User_NextValue]
as
begin
    set NOCOUNT ON


    declare @existingId int = (select isnull(max(UserId)+1, 0)  from dbo.User)

    insert into User_Seq (SeqVal) values ('a')
    declare @NewSeqValue int = scope_identity()     

    if @existingId > @NewSeqValue 
    begin  

        set identity_insert User_Seq  on
        insert into User_Seq (SeqID) values (@existingId)     
        set @NewSeqValue = scope_identity()     
    end

    delete from User_Seq WITH (READPAST)

return @NewSeqValue

Edit: The original link I answered with is now invalid.The newer URL would be https://developers.google.com/web/tools/chrome-devtools/javascript/add-breakpoints#exceptions as of 2016-11-11.

I realize this question has an answer, but it's no longer accurate. Use the link above ^

(link replaced by edited above) - you can now set it to break on all exceptions or just unhandled ones. (Note that you need to be in the Sources tab to see the button.)

Chrome's also added some other really useful breakpoint capabilities now, such as breaking on DOM changes or network events.

Normally I wouldn't re-answer a question, but I had the same question myself, and I found this now-wrong answer, so I figured I'd put this information in here for people who came along later in searching. :)

For what it's worth, for Gecko-based browsers you can't condition this thing off of :visited due to the resulting privacy leaks. See http://hacks.mozilla.org/2010/03/privacy-related-changes-coming-to-css-vistited/

Edit: You should use the json2.js library from Douglas Crockford instead of implementing the code below. It provides some extra features and better/older browser support.

Grab the json2.js file from: https://github.com/douglascrockford/JSON-js

// implement JSON.stringify serialization
JSON.stringify = JSON.stringify || function (obj) {
    var t = typeof (obj);
    if (t != "object" || obj === null) {
        // simple data type
        if (t == "string") obj = '"'+obj+'"';
        return String(obj);
    }
    else {
        // recurse array or object
        var n, v, json = [], arr = (obj && obj.constructor == Array);
        for (n in obj) {
            v = obj[n]; t = typeof(v);
            if (t == "string") v = '"'+v+'"';
            else if (t == "object" && v !== null) v = JSON.stringify(v);
            json.push((arr ? "" : '"' + n + '":') + String(v));
        }
        return (arr ? "[" : "{") + String(json) + (arr ? "]" : "}");
    }
};

var tmp = {one: 1, two: "2"};
JSON.stringify(tmp); // '{"one":1,"two":"2"}'

EDIT: Bootstrap 3.3.4 has solved this problem (and other modal issues) so if you can update your bootstrap CSS and JS that would be the best solution. If you can't update the solution below will still work and essentially does the same thing as bootstrap 3.3.4 (recalculate and apply padding).

As Bass Jobsen pointed out, newer versions of Bootstrap have the z-index solved. The modal-open class and padding-right were still problems for me but this scripts inspired by Yermo Lamers solution solves it. Just drop it in your JS file and enjoy.

$(document).on('hide.bs.modal', '.modal', function (event) {
    var padding_right = 0;
    $.each($('.modal'), function(){
        if($(this).hasClass('in') && $(this).modal().data('bs.modal').scrollbarWidth > padding_right) {
            padding_right = $(this).modal().data('bs.modal').scrollbarWidth
        }
    });
    $('body').data('padding_right', padding_right + 'px');
});

$(document).on('hidden.bs.modal', '.modal', function (event) {
    $('body').data('open_modals', $('body').data('open_modals') - 1);
    if($('body').data('open_modals') > 0) {
        $('body').addClass('modal-open');
        $('body').css('padding-right', $('body').data('padding_right'));
    }
});

$(document).on('shown.bs.modal', '.modal', function (event) {
    if (typeof($('body').data('open_modals')) == 'undefined') {
        $('body').data('open_modals', 0);
    }
    $('body').data('open_modals', $('body').data('open_modals') + 1);
    $('body').css('padding-right', (parseInt($('body').css('padding-right')) / $('body').data('open_modals') + 'px'));
});

I understand that this question is old, but there is a good solution for it in HTML5. You can wrap it all in a <figure></figure> tag. The code would look something like this:

<div id="wrapper">
<figure>

<a href="mailto:[email protected]">
<img id="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp- 
content/uploads/2012/07/email-icon-e1343123697991.jpg"/>
</a>

<a href="https://www.facebook.com/OlympiaHaacht" target="_blank">
<img id="fblogo" border="0" alt="Facebook" src="http://olympiahaacht.be/wp- 
content/uploads/2012/04/FacebookButtonRevised-e1334605872360.jpg"/>
</a>

</figure>
</div>

and the CSS:

#wrapper{
 text-align:center;
}

Check for the Classes you extend actually exists, few React methods are depreciated, It also might be a Typo error 'React.Components' instead of 'React.Component'

Good Luck!!

Try to replace 'w' for 'iw'. For example:

SELECT to_char(to_date(TRANSDATE, 'dd-mm-yyyy'), 'iw') as weeknumber from YOUR_TABLE;

I am a bit late to the party (by almost 10 years, 2 months), but one way for future coders is to do it using while loop and indexOf()

let haystack = "I learned to play the Ukulele in Lebanon.";
let needle = "le";
let pos = 0; // Position Ref
let result = []; // Final output of all index's.
let hayStackLower = haystack.toLowerCase();

// Loop to check all occurrences 
while (hayStackLower.indexOf(needle, pos) != -1) {
  result.push(hayStackLower.indexOf(needle , pos));
  pos = hayStackLower.indexOf(needle , pos) + 1;
}

console.log("Final ", result); // Returns all indexes or empty array if not found

(See here also for my C++11 answer)

In order to parse a C++ program, the compiler needs to know whether certain names are types or not. The following example demonstrates that:

t * f;

How should this be parsed? For many languages a compiler doesn't need to know the meaning of a name in order to parse and basically know what action a line of code does. In C++, the above however can yield vastly different interpretations depending on what t means. If it's a type, then it will be a declaration of a pointer f. However if it's not a type, it will be a multiplication. So the C++ Standard says at paragraph (3/7):

Some names denote types or templates. In general, whenever a name is encountered it is necessary to determine whether that name denotes one of these entities before continuing to parse the program that contains it. The process that determines this is called name lookup.

How will the compiler find out what a name t::x refers to, if t refers to a template type parameter? x could be a static int data member that could be multiplied or could equally well be a nested class or typedef that could yield to a declaration. If a name has this property - that it can't be looked up until the actual template arguments are known - then it's called a dependent name (it "depends" on the template parameters).

You might recommend to just wait till the user instantiates the template:

Let's wait until the user instantiates the template, and then later find out the real meaning of t::x * f;.

This will work and actually is allowed by the Standard as a possible implementation approach. These compilers basically copy the template's text into an internal buffer, and only when an instantiation is needed, they parse the template and possibly detect errors in the definition. But instead of bothering the template's users (poor colleagues!) with errors made by a template's author, other implementations choose to check templates early on and give errors in the definition as soon as possible, before an instantiation even takes place.

So there has to be a way to tell the compiler that certain names are types and that certain names aren't.

The "typename" keyword

The answer is: We decide how the compiler should parse this. If t::x is a dependent name, then we need to prefix it by typename to tell the compiler to parse it in a certain way. The Standard says at (14.6/2):

A name used in a template declaration or definition and that is dependent on a template-parameter is assumed not to name a type unless the applicable name lookup finds a type name or the name is qualified by the keyword typename.

There are many names for which typename is not necessary, because the compiler can, with the applicable name lookup in the template definition, figure out how to parse a construct itself - for example with T *f;, when T is a type template parameter. But for t::x * f; to be a declaration, it must be written as typename t::x *f;. If you omit the keyword and the name is taken to be a non-type, but when instantiation finds it denotes a type, the usual error messages are emitted by the compiler. Sometimes, the error consequently is given at definition time:

// t::x is taken as non-type, but as an expression the following misses an
// operator between the two names or a semicolon separating them.
t::x f;

The syntax allows typename only before qualified names - it is therefor taken as granted that unqualified names are always known to refer to types if they do so.

A similar gotcha exists for names that denote templates, as hinted at by the introductory text.

The "template" keyword

Remember the initial quote above and how the Standard requires special handling for templates as well? Let's take the following innocent-looking example:

boost::function< int() > f;

It might look obvious to a human reader. Not so for the compiler. Imagine the following arbitrary definition of boost::function and f:

namespace boost { int function = 0; }
int main() { 
  int f = 0;
  boost::function< int() > f; 
}

That's actually a valid expression! It uses the less-than operator to compare boost::function against zero (int()), and then uses the greater-than operator to compare the resulting bool against f. However as you might well know, boost::function in real life is a template, so the compiler knows (14.2/3):

After name lookup (3.4) finds that a name is a template-name, if this name is followed by a <, the < is always taken as the beginning of a template-argument-list and never as a name followed by the less-than operator.

Now we are back to the same problem as with typename. What if we can't know yet whether the name is a template when parsing the code? We will need to insert template immediately before the template name, as specified by 14.2/4. This looks like:

t::template f<int>(); // call a function template

Template names can not only occur after a :: but also after a -> or . in a class member access. You need to insert the keyword there too:

this->template f<int>(); // call a function template

Dependencies

For the people that have thick Standardese books on their shelf and that want to know what exactly I was talking about, I'll talk a bit about how this is specified in the Standard.

In template declarations some constructs have different meanings depending on what template arguments you use to instantiate the template: Expressions may have different types or values, variables may have different types or function calls might end up calling different functions. Such constructs are generally said to depend on template parameters.

The Standard defines precisely the rules by whether a construct is dependent or not. It separates them into logically different groups: One catches types, another catches expressions. Expressions may depend by their value and/or their type. So we have, with typical examples appended:

• Dependent types (e.g: a type template parameter T)
• Value-dependent expressions (e.g: a non-type template parameter N)
• Type-dependent expressions (e.g: a cast to a type template parameter (T)0)

Most of the rules are intuitive and are built up recursively: For example, a type constructed as T[N] is a dependent type if N is a value-dependent expression or T is a dependent type. The details of this can be read in section (14.6.2/1) for dependent types, (14.6.2.2) for type-dependent expressions and (14.6.2.3) for value-dependent expressions.

Dependent names

The Standard is a bit unclear about what exactly is a dependent name. On a simple read (you know, the principle of least surprise), all it defines as a dependent name is the special case for function names below. But since clearly T::x also needs to be looked up in the instantiation context, it also needs to be a dependent name (fortunately, as of mid C++14 the committee has started to look into how to fix this confusing definition).

To avoid this problem, I have resorted to a simple interpretation of the Standard text. Of all the constructs that denote dependent types or expressions, a subset of them represent names. Those names are therefore "dependent names". A name can take different forms - the Standard says:

A name is a use of an identifier (2.11), operator-function-id (13.5), conversion-function-id (12.3.2), or template-id (14.2) that denotes an entity or label (6.6.4, 6.1)

An identifier is just a plain sequence of characters / digits, while the next two are the operator + and operator type form. The last form is template-name <argument list>. All these are names, and by conventional use in the Standard, a name can also include qualifiers that say what namespace or class a name should be looked up in.

A value dependent expression 1 + N is not a name, but N is. The subset of all dependent constructs that are names is called dependent name. Function names, however, may have different meaning in different instantiations of a template, but unfortunately are not caught by this general rule.

Dependent function names

Not primarily a concern of this article, but still worth mentioning: Function names are an exception that are handled separately. An identifier function name is dependent not by itself, but by the type dependent argument expressions used in a call. In the example f((T)0), f is a dependent name. In the Standard, this is specified at (14.6.2/1).

Additional notes and examples

In enough cases we need both of typename and template. Your code should look like the following

template <typename T, typename Tail>
struct UnionNode : public Tail {
    // ...
    template<typename U> struct inUnion {
        typedef typename Tail::template inUnion<U> dummy;
    };
    // ...
};

The keyword template doesn't always have to appear in the last part of a name. It can appear in the middle before a class name that's used as a scope, like in the following example

typename t::template iterator<int>::value_type v;

In some cases, the keywords are forbidden, as detailed below

• On the name of a dependent base class you are not allowed to write typename. It's assumed that the name given is a class type name. This is true for both names in the base-class list and the constructor initializer list:

   template <typename T>
   struct derive_from_Has_type : /* typename */ SomeBase<T>::type 
   { };
  

• In using-declarations it's not possible to use template after the last ::, and the C++ committee said not to work on a solution.

   template <typename T>
   struct derive_from_Has_type : SomeBase<T> {
      using SomeBase<T>::template type; // error
      using typename SomeBase<T>::type; // typename *is* allowed
   };
  

If you are willing to use std::array instead of built-in arrays, you may use:

std::array<int, 5> iar1 = {1,2,3,4,5};
std::array<int, 5> iar2 = {1,2,3,4,5};

if (iar1 == iar2)

Map is an interface, i.e. an abstract "thing" that defines how something can be used. HashMap is an implementation of that interface.

Try Glogg. the fast, smart log explorer.

I have opened log file of size around 2 GB, and the search is also very fast.

Why don't you do:

$("#radio1, #radio2, #radio3, #radio4").checked = false;

use app.render in scenarios where you need to render a view but not send it to a client via http. html emails springs to mind.

Here is the batch file which should work for you:

@echo off
Title HOST: Installing updates on %computername%
echo %computername%
set Server=\\SERVERNAME or PATH\msifolder

:select
cls
echo Select one of the following MSI install folders for installation task.
echo.
dir "%Server%" /AD /ON /B
echo.
set /P "MSI=Please enter the MSI folder to install: "
set "Package=%Server%\%MSI%\%MSI%.msi"

if not exist "%Package%" (
   echo.
   echo The entered folder/MSI file does not exist ^(typing mistake^).
   echo.
   setlocal EnableDelayedExpansion
   set /P "Retry=Try again [Y/N]: "
   if /I "!Retry!"=="Y" endlocal & goto select
   endlocal
   goto :EOF
)

echo.
echo Selected installation: %MSI%
echo.
echo.

:verify
echo Is This Correct?
echo.
echo.
echo    0: ABORT INSTALL
echo    1: YES
echo    2: NO, RE-SELECT
echo.
set /p "choice=Select YES, NO or ABORT? [0,1,2]: "
if [%choice%]==[0] goto :EOF
if [%choice%]==[1] goto yes
goto select

:yes
echo.
echo Running %MSI% installation ...
start "Install MSI" /wait "%SystemRoot%\system32\msiexec.exe" /i /quiet "%Package%"

The characters listed on last page output on entering in a command prompt window either help cmd or cmd /? have special meanings in batch files. Here are used parentheses and square brackets also in strings where those characters should be interpreted literally. Therefore it is necessary to either enclose the string in double quotes or escape those characters with character ^ as it can be seen in code above, otherwise command line interpreter exits batch execution because of a syntax error.

And it is not possible to call a file with extension MSI. A *.msi file is not an executable. On double clicking on a MSI file, Windows looks in registry which application is associated with this file extension for opening action. And the application to use is msiexec with the command line option /i to install the application inside MSI package.

Run msiexec.exe /? to get in a GUI window the available options or look at Msiexec (command-line options).

I have added already /quiet additionally to required option /i for a silent installation.

In batch code above command start is used with option /wait to start Windows application msiexec.exe and hold execution of batch file until installation finished (or aborted).

When working to create Cross Browser Favicons (including touch icons) there are several things to consider.

The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:

<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon" for IE to recognize the icon it needs the word shortcut which is not standard. Also we wrap the .ico favicon in a IE conditional comment because Chrome and Safari will use the .ico file if it is present, despite other options available, not what we would like.

The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.

For the rest of the browsers we are going to use the standard way to cite a favicon:

<link rel="icon" href="path/to/favicon.png">

This icon should be 196x196 pixels in size to cover all devices that may use this icon.

To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:

<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

Using rel="apple-touch-icon-precomposed" will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon". This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed".

As a note: Chrome for Android states:

The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).

Custom Tiles for IE 11+ on Windows 8.1+

IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.

Microsoft recommends creating a few tiles at the following size:

Small: 128 x 128

Medium: 270 x 270

Wide: 558 x 270

Large: 558 x 558

These should be transparent images as we will define a color background next.

Once these images are created you should create an xml file called browserconfig.xml with the following code:

<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
  <msapplication>
    <tile>
      <square70x70logo src="images/smalltile.png"/>
      <square150x150logo src="images/mediumtile.png"/>
      <wide310x150logo src="images/widetile.png"/>
      <square310x310logo src="images/largetile.png"/>
      <TileColor>#009900</TileColor>
    </tile>
  </msapplication>
</browserconfig>

Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head:

<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />

For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.

Putting it all together:

To put it all together the above code would look like this:

<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. --> 
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">

Windows Phone Live Tiles

If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:

Here are detailed instructions from Microsoft but here is a synopsis:

Step 1

Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.

Step 2

Add a hidden overlay of this image. Here is example code from Microsoft:

<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
  <img src="customtile.png" width="320" height="320" />
  <div style='margin-top: 40px'>
     Add text/graphic asking user to pin to start using the menu...
  </div>
</div>

Step 3

You then can add thew following line to add a pin to start link:

<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>

Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.

Step 4

Next you add some JS to toggle the overlay visibility

<script>
function ToggleTileOverlay() {
 var newVisibility =     (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
 document.getElementById('TileOverlay').style.visibility =    newVisibility;
}
</script>

Note on Sizes

I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.

I did the anaconda install but matplotlib is not plotting

It starts plotting when i did this

import matplotlib
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline  

You will also get this if git doesn't have permissions to read the config files. It will just go up in the hierarchy tree until it needs to cross file systems.

Number.prototype.trim = function(decimals) {
    var s = this.toString();
    var d = s.split(".");
    d[1] = d[1].substring(0, decimals);
    return parseFloat(d.join("."));
}

console.log((5.676).trim(2)); //logs 5.67

to answer to your second question - performance IS affected - if you are using those selectors with a single (no nested) ul:

<ul>
    <li>jjj</li>
    <li>jjj</li>    
    <li>jjj</li>
</ul>

the child selector ul > li is more performant than ul li because it is more specific. the browser traverse the dom "right to left", so when it finds a li it then looks for a any ul as a parent in the case of a child selector, while it has to traverse the whole dom tree to find any ul ancestors in case of the descendant selector

The entire story begins with a feature of swift called optional vars. These are the vars which may have a value or may not have a value. In general swift doesn't allow us to use a variable which isn't initialised, as this may lead to crashes or unexpected reasons and also server a placeholder for backdoors. Thus in order to declare a variable whose value isn't initially determined we use a '?'. When such a variable is declared, to use it as a part of some expression one has to unwrap them before use, unwrapping is an operation through which value of a variable is discovered this applies to objects. Without unwrapping if you try to use them you will have compile time error. To unwrap a variable which is an optional var, exclamation mark "!" is used.

Now there are times when you know that such optional variables will be assigned values by system for example or your own program but sometime later , for example UI outlets, in such situation instead of declaring an optional variable using a question mark "?" we use "!".

Thus system knows that this variable which is declared with "!" is optional right now and has no value but will receive a value in later in its lifetime.

Thus exclamation mark holds two different usages, 1. To declare a variable which will be optional and will receive value definitely later 2. To unwrap an optional variable before using it in an expression.

Above descriptions avoids too much of technical stuff, i hope.

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

There are several possibilities (note that the those long values aren't the same as the Unix epoch.

For your example (to reverse ToFileTime()) just use DateTime.FromFileTime(t).

My version for a directive that uses jqplot to plot the data once it becomes available:

    app.directive('lineChart', function() {
        $.jqplot.config.enablePlugins = true;

        return function(scope, element, attrs) {
            scope.$watch(attrs.lineChart, function(newValue, oldValue) {
                if (newValue) {
                    // alert(scope.$eval(attrs.lineChart));
                    var plot = $.jqplot(element[0].id, scope.$eval(attrs.lineChart), scope.$eval(attrs.options));
                }
            });
        }
});

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

In Qt5 you should use QtWidgets instead of QtGui

#include <QtGui/QComboBox>     // incorrect in QT5
#include <QtWidgets/QComboBox>    // correct in QT5

Or

#include <QtGui/QStringListModel>    // incorrect in QT5
#include <QtCore/QStringListModel>    // correct in QT5

One of my favorites is realpath foo

realpath - return the canonicalized absolute pathname

realpath  expands  all  symbolic  links  and resolves references to '/./', '/../' and extra '/' characters in the null terminated string named by path and
       stores the canonicalized absolute pathname in the buffer of size PATH_MAX named by resolved_path.  The resulting path will have no symbolic link, '/./' or
       '/../' components.

The most simple and straightforward C/C++ implementation that I found is in a link at the bottom of this page:

Web Page: http://www.barrgroup.com/Embedded-Systems/How-To/CRC-Calculation-C-Code

Code Download Link: https://barrgroup.com/code/crc.zip

It is a simple standalone implementation with one .h and one .c file. There is support for CRC32, CRC16 and CRC_CCITT thru the use of a define. Also, the code lets the user change parameter settings like the CRC polynomial, initial/final XOR value, and reflection options if you so desire.

The license is not explicitly defined ala LGPL or similar. However the site does say that they are placing the code in the public domain for any use. The actual code files also say this.

Hope it helps!

You should try something like this

List xx= (List) list.get(0)
String id = (String) xx.get(0)

or if you have a House value object the result of the query is of the same type, then

House myhouse = (House) list.get(0);

For getting the first 5 elements of an array, all you need to do is slice the array in question. In Swift, you do it like this: array[0..<5].

To make picking the N first elements of an array a bit more functional and generalizable, you could create an extension method for doing it. For instance:

extension Array {
    func takeElements(var elementCount: Int) -> Array {
        if (elementCount > count) {
            elementCount = count
        }
        return Array(self[0..<elementCount])
    }
}

string.punctuation misses loads of punctuation marks that are commonly used in the real world. How about a solution that works for non-ASCII punctuation?

import regex
s = u"string. With. Some·Really Weird?Non?ASCII? ?(Punctuation)??"
remove = regex.compile(ur'[\p{C}|\p{M}|\p{P}|\p{S}|\p{Z}]+', regex.UNICODE)
remove.sub(u" ", s).strip()

Personally, I believe this is the best way to remove punctuation from a string in Python because:

• It removes all Unicode punctuation
• It's easily modifiable, e.g. you can remove the \{S} if you want to remove punctuation, but keep symbols like $.
• You can get really specific about what you want to keep and what you want to remove, for example \{Pd} will only remove dashes.
• This regex also normalizes whitespace. It maps tabs, carriage returns, and other oddities to nice, single spaces.

This uses Unicode character properties, which you can read more about on Wikipedia.

I faced the same problem, and resolved it by changing the BodyStyle attribut value to "WebMessageBodyStyle.Bare" :

[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json, UriTemplate = "GetProjectWithGeocodings/{projectId}")]
GeoCod_Project GetProjectWithGeocodings(string projectId);

The returned object will no longer be wrapped.

You can create a extension method:

public static IEnumerable<T> Do<T>(this IEnumerable<T> self, Action<T> action) {
    foreach(var item in self) {
        action(item);
        yield return item;
    }
}

And then use it in code:

listofCompany.Do(d=>d.Id = 1);
listofCompany.Where(d=>d.Name.Contains("Inc")).Do(d=>d.Id = 1);

I would prefer using the most easiest method.

For a soft impact animation solution:

Swift 3:

let indexPath = IndexPath(item: row, section: 0)
tableView.reloadRows(at: [indexPath], with: .fade)

Swift 2.x:

let indexPath = NSIndexPath(forRow: row, inSection: 0)
tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)

This is another way to protect the app from crashing:

Swift 3:

let indexPath = IndexPath(item: row, section: 0)
if let visibleIndexPaths = tableView.indexPathsForVisibleRows?.index(of: indexPath as IndexPath) {
    if visibleIndexPaths != NSNotFound {
        tableView.reloadRows(at: [indexPath], with: .fade)
    }
}

Swift 2.x:

let indexPath = NSIndexPath(forRow: row, inSection: 0)
if let visibleIndexPaths = tableView.indexPathsForVisibleRows?.indexOf(indexPath) {
   if visibleIndexPaths != NSNotFound {
      tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
   }
}
