On bootstrap-modal.js v2.2.0:

( $('element').data('modal') || {}).isShown

You should avoid using global vars, and prefer using .data()

So, you'd do:

jQuery('#id').click(function(){
  $(this).data('clicked', true);
});

Then, to check if it was clicked and perform an action:

if(jQuery('#id').data('clicked')) {
    //clicked element, do-some-stuff
} else {
    //run function2
}

Hope this helps. Cheers

A straightforward approach:

def round_time(dt, round_to_seconds=60):
    """Round a datetime object to any number of seconds
    dt: datetime.datetime object
    round_to_seconds: closest number of seconds for rounding, Default 1 minute.
    """
    rounded_epoch = round(dt.timestamp() / round_to_seconds) * round_to_seconds
    rounded_dt = datetime.datetime.fromtimestamp(rounded_epoch).astimezone(dt.tzinfo)
    return rounded_dt

You can use class System.Array for add new element:

Array.Resize(ref objArray, objArray.Length + 1);
objArray[objArray.Length - 1] = new Someobject();

You can also use Parser() from html-react-parser. I have used the same. Link shared.

I was able to solve this by removing the [&TotalPages] builtin field from the bottom. The time when down from minutes to less than a second.

Something odd that I could not determined was having impact on the calculation of total pages.

I was using SSRS 2012.

Using with FILEPATH option might work:

set(CMAKE_CXX_COMPILER:FILEPATH C:/MinGW/bin/gcc.exe)

An MSI is a Windows Installer database. Windows Installer (a service installed with Windows) uses this to install software on your system (i.e. copy files, set registry values, etc...).

A setup.exe may either be a bootstrapper or a non-msi installer. A non-msi installer will extract the installation resources from itself and manage their installation directly. A bootstrapper will contain an MSI instead of individual files. In this case, the setup.exe will call Windows Installer to install the MSI.

Some reasons you might want to use a setup.exe:

• Windows Installer only allows one MSI to be installing at a time. This means that it is difficult to have an MSI install other MSIs (e.g. dependencies like the .NET framework or C++ runtime). Since a setup.exe is not an MSI, it can be used to install several MSIs in sequence.
• You might want more precise control over how the installation is managed. An MSI has very specific rules about how it manages the installations, including installing, upgrading, and uninstalling. A setup.exe gives complete control over the software configuration process. This should only be done if you really need the extra control since it is a lot of work, and it can be tricky to get it right.

DAO is an abstraction of data persistence.
Repository is an abstraction of a collection of objects.

DAO would be considered closer to the database, often table-centric.
Repository would be considered closer to the Domain, dealing only in Aggregate Roots.

Repository could be implemented using DAO's, but you wouldn't do the opposite.

Also, a Repository is generally a narrower interface. It should be simply a collection of objects, with a Get(id), Find(ISpecification), Add(Entity).

A method like Update is appropriate on a DAO, but not a Repository - when using a Repository, changes to entities would usually be tracked by separate UnitOfWork.

It does seem common to see implementations called a Repository that is really more of a DAO, and hence I think there is some confusion about the difference between them.

Considering the String class' length method returns an int, the maximum length that would be returned by the method would be Integer.MAX_VALUE, which is 2^31 - 1 (or approximately 2 billion.)

In terms of lengths and indexing of arrays, (such as char[], which is probably the way the internal data representation is implemented for Strings), Chapter 10: Arrays of The Java Language Specification, Java SE 7 Edition says the following:

The variables contained in an array have no names; instead they are referenced by array access expressions that use nonnegative integer index values. These variables are called the components of the array. If an array has n components, we say n is the length of the array; the components of the array are referenced using integer indices from 0 to n - 1, inclusive.

Furthermore, the indexing must be by int values, as mentioned in Section 10.4:

Arrays must be indexed by int values;

Therefore, it appears that the limit is indeed 2^31 - 1, as that is the maximum value for a nonnegative int value.

However, there probably are going to be other limitations, such as the maximum allocatable size for an array.

Edit: 2-15-2012 This is how to use FB authentication for a localhost website.

I find it more scalable and convenient to set up a second Facebook app. If I'm building MyApp, then I'll make a second one called MyApp-dev.

• Create a new app at https://developers.facebook.com/apps
• (New 2/15/2012) Click the Website checkbox under 'Select how your application integrates with Facebook' (In the recent Facebook version you can find this under Settings > Basic > Add Platform - Then select website)
• Set the Site URL field (NOT the App Domains field) to http://www.localhost:3000 (this address is for Ruby on Rails, change as needed)

• In your application initializer, put in code to detect the environment
  • Sample Rails 3 code

    if Rails.env == 'development' || Rails.env == 'test'
      Rails.application.config.middleware.use OmniAuth::Builder do
        provider :facebook, 'DEV_APP_ID', 'DEV_APP_SECRET'
      end
    else
      # Production
      Rails.application.config.middleware.use OmniAuth::Builder do
        provider :facebook, 'PRODUCTION_APP_ID', 'PRODUCTION_APP_SECRET'
      end
    end
    

I prefer this method because once it's set up, coworkers and other machines don't have additional setup.

Look at the open function in Perl - especially the variants using a '|' (pipe) in the arguments. Done correctly, you'll get a file handle that you can use to read the output of the command. The back tick operators also do this.

You might also want to review whether Perl has access to the C functions that the command itself uses. For example, for ls -a, you could use the opendir function, and then read the file names with the readdir function, and finally close the directory with (surprise) the closedir function. This has a number of benefits - precision probably being more important than speed. Using these functions, you can get the correct data even if the file names contain odd characters like newline.

You can use new Date().getTime() for getting timestamps. Then you can calculate the difference between end and start and finally transform the timestamp which is ms into s.

const start = new Date().getTime();
const end = new Date().getTime();

const diff = end - start;
const seconds = Math.floor(diff / 1000 % 60);

I was having the same problem running a single-node pseudo-distributed instance. Couldn't figure out how to solve it, but a quick workaround is to manually start a DataNode with

Think this is, what you are searching for: Allow access to specific projects for Users

Short description without screenshots:
Use Jenkins "Project-based Matrix Authorization Strategy" under "Manage Jenkins" => "Configure System". On the configuration page of each project, you now have "Enable project-based security". Now add each user you want to authorize.

To add a little bit more information that confused me; I had always thought the same result could be achieved like so;

theDate.ToString("yyyy-MM-dd HH:mm:ss")

However, If your Current Culture doesn't use a colon(:) as the hour separator, and instead uses a full-stop(.) it could return as follow:

2009-06-15 13.45.30

Just wanted to add why the answer provided needs to be as it is;

theDate.ToString("yyyy-MM-dd HH':'mm':'ss")

:-)

/* eslint no-restricted-globals:0 */

is another alternate approach

My problem was took IBOutlet but didn't connect with interface builder and using in swift file.

A simple way to see the Git commit short version and the Git commit message is:

git log --oneline

Note that this is shorthand for

git log --pretty=oneline --abbrev-commit

I have used this query in our production code for nearly 10 years:

SELECT FLOOR((CAST (GetDate() AS INTEGER) - CAST(Date_of_birth AS INTEGER)) / 365.25) AS Age

PNG supports alphachannel transparency.

TIFF can have extended options I.e. Geo referencing for GIS applications.

I recommend only ever using JPEG for photographs, never for images like clip art, logos, text, diagrams, line art.

Favor PNG.

public void setItem(List<Item> dataEntity, Item item) {
    int itemIndex = dataEntity.indexOf(item);
    if (itemIndex != -1) {
        dataEntity.set(itemIndex, item);
    }
}

If you want to provide a timeout for a particular query, then CommandTimeout is the way forward.

Its usage is:

command.CommandTimeout = 60; //The time in seconds to wait for the command to execute. The default is 30 seconds.

I stugeled to find out the boost version number in bash.

Ended up doing following, which stores the version code in a variable, supressing the errors. This uses the example from maxschlepzig in the comments of the accepted answer. (Can not comment, don't have 50 Rep)

I know this has been answered long time ago. But I couldn't find how to do it in bash anywhere. So I thought this might help someone with the same problem. Also this should work no matter where boost is installed, as long as the comiler can find it. And it will give you the version number that is acutally used by the comiler, when you have multiple versions installed.

{
VERS=$(echo -e '#include <boost/version.hpp>\nBOOST_VERSION' | gcc -s -x c++ -E - | grep "^[^#;]")
} &> /dev/null

Check if you mixed tabs and spaces, that is a frequent source of indentation errors.

View

1. View objects are the basic building blocks of User Interface(UI) elements in Android.
2. View is a simple rectangle box which responds to the user's actions.
3. Examples are EditText, Button, CheckBox etc..
4. View refers to the android.view.View class, which is the base class of all UI classes.

ViewGroup

1. ViewGroup is the invisible container. It holds View and ViewGroup
2. For example, LinearLayout is the ViewGroup that contains Button(View), and other Layouts also.
3. ViewGroup is the base class for Layouts.

The former answer is now superseded by .iloc:

>>> df = pd.DataFrame({"date": range(10, 64, 8)})
>>> df.index += 17
>>> df
    date
17    10
18    18
19    26
20    34
21    42
22    50
23    58
>>> df["date"].iloc[0]
10
>>> df["date"].iloc[-1]
58

The shortest way I can think of uses .iget():

>>> df = pd.DataFrame({"date": range(10, 64, 8)})
>>> df.index += 17
>>> df
    date
17    10
18    18
19    26
20    34
21    42
22    50
23    58
>>> df['date'].iget(0)
10
>>> df['date'].iget(-1)
58

Alternatively:

>>> df['date'][df.index[0]]
10
>>> df['date'][df.index[-1]]
58

There's also .first_valid_index() and .last_valid_index(), but depending on whether or not you want to rule out NaNs they might not be what you want.

Remember that df.ix[0] doesn't give you the first, but the one indexed by 0. For example, in the above case, df.ix[0] would produce

>>> df.ix[0]
Traceback (most recent call last):
  File "<ipython-input-489-494245247e87>", line 1, in <module>
    df.ix[0]

The OP's code snippet clearly uses the correct comment markup but CSS can break in a progressive way — so, if there's a syntax error, everything after that is likely to fail. A couple times I've relied on trustworthy sources that supplied incorrect comment markup that broke my style sheet. Since the OP provided just a small section of their code, I'd suggest the following:

Make sure all of your CSS comments use this markup /* ... */ -- which is the correct comment markup for css according to MDN

Validate your css with a linter or a secure online validator. Here's one by W3

More info: I went to check the latest recommended media query breakpoints from bootstrap 4 and ended up copying the boiler plate straight from their docs. Almost every code block was labeled with javascript-style comments //, which broke my code — and gave me only cryptic compile errors with which to troubleshoot, which went over my head at the time and caused me sadness.

IntelliJ text editor allowed me to comment out specific lines of css in a LESS file using the ctrl+/ hotkey which was great except it inserts // by default on unrecognized file types. It isn't freeware and less is fairly mainstream so I trusted it and went with it. That broke my code. There's a preference menu for teaching it the correct comment markup for each filetype.

There is a "3 of 9" control on CodeProject: Barcode .NET Control

With explode function of php

$array=explode(" ",$str); 

This is a quick example for you http://codepad.org/Pbg4n76i

There are currently three distinct events which may or may not be triggered when the client devices moves. Two of them are focused around orientation and the last on motion:

• ondeviceorientation is known to work on the desktop version of Chrome, and most Apple laptops seems to have the hardware required for this to work. It also works on Mobile Safari on the iPhone 4 with iOS 4.2. In the event handler function, you can access alpha, beta, gamma values on the event data supplied as the only argument to the function.

• onmozorientation is supported on Firefox 3.6 and newer. Again, this is known to work on most Apple laptops, but might work on Windows or Linux machines with accelerometer as well. In the event handler function, look for x, y, z fields on the event data supplied as first argument.

• ondevicemotion is known to work on iPhone 3GS + 4 and iPad (both with iOS 4.2), and provides data related to the current acceleration of the client device. The event data passed to the handler function has acceleration and accelerationIncludingGravity, which both have three fields for each axis: x, y, z

The "earthquake detecting" sample website uses a series of if statements to figure out which event to attach to (in a somewhat prioritized order) and passes the data received to a common tilt function:

if (window.DeviceOrientationEvent) {
    window.addEventListener("deviceorientation", function () {
        tilt([event.beta, event.gamma]);
    }, true);
} else if (window.DeviceMotionEvent) {
    window.addEventListener('devicemotion', function () {
        tilt([event.acceleration.x * 2, event.acceleration.y * 2]);
    }, true);
} else {
    window.addEventListener("MozOrientation", function () {
        tilt([orientation.x * 50, orientation.y * 50]);
    }, true);
}

The constant factors 2 and 50 are used to "align" the readings from the two latter events with those from the first, but these are by no means precise representations. For this simple "toy" project it works just fine, but if you need to use the data for something slightly more serious, you will have to get familiar with the units of the values provided in the different events and treat them with respect :)

style.css

.nice-style {

}

script JavaScript

const addStyle = document.getElementById("myElement"); addStyle.classList.add('nice-style');

To use Redux-saga is the best middleware in React-redux implementation.

Ex: store.js

  import createSagaMiddleware from 'redux-saga';
  import { createStore, applyMiddleware } from 'redux';
  import allReducer from '../reducer/allReducer';
  import rootSaga from '../saga';

  const sagaMiddleware = createSagaMiddleware();
  const store = createStore(
     allReducer,
     applyMiddleware(sagaMiddleware)
   )

   sagaMiddleware.run(rootSaga);

 export default store;

And then saga.js

import {takeLatest,delay} from 'redux-saga';
import {call, put, take, select} from 'redux-saga/effects';
import { push } from 'react-router-redux';
import data from './data.json';

export function* updateLesson(){
   try{
       yield put({type:'INITIAL_DATA',payload:data}) // initial data from json
       yield* takeLatest('UPDATE_DETAIL',updateDetail) // listen to your action.js 
   }
   catch(e){
      console.log("error",e)
     }
  }

export function* updateDetail(action) {
  try{
       //To write store update details
   }  
    catch(e){
       console.log("error",e)
    } 
 }

export default function* rootSaga(){
    yield [
        updateLesson()
       ]
    }

And then action.js

 export default function updateFruit(props,fruit) {
    return (
       {
         type:"UPDATE_DETAIL",
         payload:fruit,
         props:props
       }
     )
  }

And then reducer.js

import {combineReducers} from 'redux';

const fetchInitialData = (state=[],action) => {
    switch(action.type){
      case "INITIAL_DATA":
          return ({type:action.type, payload:action.payload});
          break;
      }
     return state;
  }
 const updateDetailsData = (state=[],action) => {
    switch(action.type){
      case "INITIAL_DATA":
          return ({type:action.type, payload:action.payload});
          break;
      }
     return state;
  }
const allReducers =combineReducers({
   data:fetchInitialData,
   updateDetailsData
 })
export default allReducers; 

And then main.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './app/components/App.jsx';
import {Provider} from 'react-redux';
import store from './app/store';
import createRoutes from './app/routes';

const initialState = {};
const store = configureStore(initialState, browserHistory);

ReactDOM.render(
       <Provider store={store}>
          <App />  /*is your Component*/
       </Provider>, 
document.getElementById('app'));

try this.. is working

You can use whereIn which accepts an array as second paramter.

DB:table('table')
   ->whereIn('column', [value, value, value])
   ->get()

You can chain where multiple times.

DB:table('table')->where('column', 'operator', 'value')
    ->where('column', 'operator', 'value')
    ->where('column', 'operator', 'value')
    ->get();

This will use AND operator. if you need OR you can use orWhere method.

For advanced where statements

DB::table('table')
    ->where('column', 'operator', 'value')
    ->orWhere(function($query)
    {
        $query->where('column', 'operator', 'value')
            ->where('column', 'operator', 'value');
    })
    ->get();

Just in case you don't want to use stored proc, here's a simple query version

select * 
  from information_schema.columns 
 where table_name = 'aspnet_Membership'
 order by ordinal_position

"Where should I copy ICSharpCode.SharpZipLib.dll to see that namespace in Visual Studio?"

You need to add the dll file as a reference in your project. Right click on References in the Solution Explorer->Add Reference->Browse and then select the dll.

Finally you'll need to add it as a using statement in whatever files you want to use it in.

This works fine. Checked in chrome browser:

var theDate = new Date(timeStamp_value * 1000);
dateString = theDate.toGMTString();
alert(dateString );

This is how I would go about this:

1. Start a ServerSocket listening (probably on port 80).
2. Once you get a connection request, accept and pass to another thread/process (this leaves your ServerSocket available to keep listening and accept other connections).
3. Parse the request text (specifically, the headers where you will see if it is a GET or POST, and the parameters passed.
4. Answer with your own headers (Content-Type, etc.) and the HTML.

I find it useful to use Firebug (in Firefox) to see examples of headers. This is what you want to emulate.

All you need is to give the AnchorPane an ID, and then you can get the Stage from that.

@FXML private AnchorPane ap;
Stage stage = (Stage) ap.getScene().getWindow();

From here, you can add in the Listener that you need.

Edit: As stated by EarthMind below, it doesn't have to be the AnchorPane element; it can be any element that you've defined.

For Actionbar:

getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeAsUpIndicator(R.drawable.ic_action_back);

For Toolbar:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_action_back);

Swift 2.0:

1)

//  AppDelegate.swift

import UIKit
import Foundation

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?
 var splashTimer:NSTimer?
 var splashImageView:UIImageView?

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  window = UIApplication.sharedApplication().delegate!.window!

  let splashImage: UIImage = UIImage(named: "ic_120x120.png")!
  splashImageView = UIImageView(image: splashImage)
  splashImageView!.frame = CGRectMake(0, 0, (window?.frame.width)!, (window?.frame.height)!)

  window!.addSubview(splashImageView!)
  window!.makeKeyAndVisible()

  //Adding splash Image as UIWindow's subview.
  window!.bringSubviewToFront(window!.subviews[0])

  // Here specify the timer.
  splashTimer = NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "splashTimerForLoadingScreen", userInfo: nil, repeats: true)

  return true
 }
 func splashTimerForLoadingScreen() {
  splashImageView!.removeFromSuperview()
  splashTimer!.invalidate()
 }

2)

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  NSThread.sleepForTimeInterval(9)

  OR

  sleep(9)

  return true
 }

3) Using root view controller concept:

//  AppDelegate.swift

import UIKit
import Foundation

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?
 var splashTimer:NSTimer?
 var storyboard:UIStoryboard?

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  window =  UIWindow(frame: UIScreen.mainScreen().bounds)
  window?.makeKeyAndVisible()

  storyboard = UIStoryboard(name: "Main", bundle: nil)

  //Here set the splashScreen VC
  let rootController = storyboard!.instantiateViewControllerWithIdentifier("secondVCID")

  if let window = self.window {
   window.rootViewController = rootController
  }

  //Set Timer
  splashTimer = NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "splashTimerCrossedTimeLimit", userInfo: nil, repeats: true)

  return true
 }
 func splashTimerCrossedTimeLimit(){

  //Here change the root controller
  let rootController = storyboard!.instantiateViewControllerWithIdentifier("firstVCID")
  if let window = self.window {
   window.rootViewController = rootController
  }
  splashTimer?.invalidate()
 }

Normally, pip will clean up after itself and remove the contents of the build directory. The only time it doesn't do this is if:

1. You used the --no-install option
2. You are using editable packages
3. The installation was cancelled or was otherwise interrupted.

In all other cases, you shouldn't have build directory that's clogging your environment.

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Zapping - you can use this javascript lib; DefiantJS. There is no need to restructure JSON data into objects to ease searching. Instead, you can search the JSON structure with an XPath expression like this:

    var data = [
   {
      "id": "one",
      "pId": "foo1",
      "cId": "bar1"
   },
   {
      "id": "two",
      "pId": "foo2",
      "cId": "bar2"
   },
   {
      "id": "three",
      "pId": "foo3",
      "cId": "bar3"
   }
],
res = JSON.search( data, '//*[id="one"]' );

console.log( res[0].cId );
// 'bar1'

DefiantJS extends the global object JSON with a new method; "search" which returns array with the matches (empty array if none were found). You can try it out yourself by pasting your JSON data and testing different XPath queries here:

http://www.defiantjs.com/#xpath_evaluator

XPath is, as you know, a standardised query language.

You only have tried comma-separated and semicolon-separated CSV. If you had tried tab-separated CSV (also called TSV) you would have found the answer:

UTF-16LE with BOM (byte order mark), tab-separated

But: In a comment you mention that TSV is not an option for you (I haven't been able to find this requirement in your question though). That's a pity. It often means that you allow manual editing of TSV files, which probably is not a good idea. Visual checking of TSV files is not a problem. Furthermore editors can be set to display a special character to mark tabs.

And yes, I tried this out on Windows and Mac.

The way I am doing is using Emacs with docker package installed. I would recommend Spacemacs version of Emacs. I would follow the following steps:

1) Install Emacs (Instruction) and install Spacemacs (Instruction)

2) Add docker in your .spacemacs file

3) Start Emacs

4) Find file (SPC+f+f) and type /docker:<container-id>:/<path of dir/file in the container>

5) Now your emacs will use the container environment to edit the files

Thanks for pointing toward the correct answer.

I have just checked the Golang FAQ (duh) and it clearly states, this is not available in the language:

Does Go have the ?: operator?

There is no ternary form in Go. You may use the following to achieve the same result:

if expr {
    n = trueVal
} else {
    n = falseVal
}

I approached this in a slightly different way and it worked for me;

I needed to remove secure_links from my table that referenced the conditions table where there were no longer any condition rows left. A housekeeping script basically. This gave me the error - You cannot specify target table for delete.

So looking here for inspiration I came up with the below query and it works just fine. This is because it creates a temporary table sl1 that is used as the reference for the DELETE.

DELETE FROM `secure_links` WHERE `secure_links`.`link_id` IN 
            (
            SELECT
                `sl1`.`link_id` 
            FROM 
                (
                SELECT 

                    `sl2`.`link_id` 

                FROM 
                    `secure_links` AS `sl2` 
                    LEFT JOIN `conditions` ON `conditions`.`job` = `sl2`.`job` 

                WHERE 

                    `sl2`.`action` = 'something' AND 
                    `conditions`.`ref` IS NULL 
                ) AS `sl1`
            )

Works for me.

Post-link function

When the post-link function is called, all previous steps have taken place - binding, transclusion, etc.

This is typically a place to further manipulate the rendered DOM.

Do:

• Manipulate DOM (rendered, and thus instantiated) elements.
• Attach event handlers.
• Inspect child elements.
• Set up observations on attributes.
• Set up watches on the scope.

UPDATE: 7/20/2018 - Added links and updated name for coverageReporters.

UPDATE: 8/14/2017 - This answer is totally outdated. Just look at the Jest docs now. They have official support and documentation about how to do this.

@hankhsiao has got a forked repo where Istanbul is working with Jest. Add this to your dev dependencies

 "devDependencies": {
     "jest-cli": "git://github.com/hankhsiao/jest.git"
 }

Also make sure coverage is enabled in your package.json jest entry and you can also specify formats you want. (The html is pretty bad ass).

 "jest": {
     "collectCoverage": true,
     "coverageReporters": ["json", "html"],
 }

See Jest documentation for coverageReporters (default is ["json", "lcov", "text"])

Or add --coverage when you invoke jest.

I think modifying a "selected text" in a RichTextBox isn't the right way to add colored text. So here a method to add a "color block" :

        Run run = new Run("This is my text");
        run.Foreground = new SolidColorBrush(Colors.Red); // My Color
        Paragraph paragraph = new Paragraph(run);
        MyRichTextBlock.Document.Blocks.Add(paragraph);

From MSDN :

The Blocks property is the content property of RichTextBox. It is a collection of Paragraph elements. Content in each Paragraph element can contain the following elements:

• Inline

• InlineUIContainer

• Run

• Span

• Bold

• Hyperlink

• Italic

• Underline

• LineBreak

So I think you have to split your string depending on parts color, and create as many Run objects as needed.

You use

#main_text .title {
  /* Properties */
}

If you just put a space between the selectors, styles will apply to all children (and children of children) of the first. So in this case, any child element of #main_text with the class name title. If you use > instead of a space, it will only select the direct child of the element, and not children of children, e.g.:

#main_text > .title {
  /* Properties */
}

Either will work in this case, but the first is more typically used.

As mentioned in the previous posts, using an HttpServletReqiestWrapper is the way to go, however the missed part in those posts was that apart from overriding the method getParameter(), you should also override other parameter related methods to produce a consistent response. e.g. the value of a param added by the custom request wrapper should also be included in the parameters map returned by the method getParameterMap(). Here is an example:

   public class AddableHttpRequest extends HttpServletRequestWrapper {

    /** A map containing additional request params this wrapper adds to the wrapped request */
    private final Map<String, String> params = new HashMap<>();

    /**
     * Constructs a request object wrapping the given request.
     * @throws java.lang.IllegalArgumentException if the request is null
     */
    AddableHttpRequest(final HttpServletRequest request) {
        super(request)
    }

    @Override
    public String getParameter(final String name) {
        // if we added one with the given name, return that one
        if ( params.get( name ) != null ) {
            return params.get( name );
        } else {
            // otherwise return what's in the original request
            return super.getParameter(name);
        }
    }


    /**
     * *** OVERRIDE THE METHODS BELOW TO REFLECT PARAMETERS ADDED BY THIS WRAPPER ****
     */

    @Override
    public Map<String, String> getParameterMap() {
        // defaulf impl, should be overridden for an approprivate map of request params
        return super.getParameterMap();
    }

    @Override
    public Enumeration<String> getParameterNames() {
        // defaulf impl, should be overridden for an approprivate map of request params names
        return super.getParameterNames();
    }

    @Override
    public String[] getParameterValues(final String name) {
        // defaulf impl, should be overridden for an approprivate map of request params values
        return super.getParameterValues(name);
    }
}

Http 415 Media Unsupported is responded back only when the content type header you are providing is not supported by the application.

With POSTMAN, the Content-type header you are sending is Content type 'multipart/form-data not application/json. While in the ajax code you are setting it correctly to application/json. Pass the correct Content-type header in POSTMAN and it will work.

If you do it a lot I would suggest writing a function that compares the two structures. That way, if you ever change the structure you only need to change the compare in one place.

As for how to do it.... You need to compare every element individually

function TellFirstCharacterType(inputString){
    var firstCharacter = inputString[0];
    if(isNaN(firstCharacter)){
        if(firstCharacter == firstCharacter.toUpperCase()){
            return "It's a uppercase character";
        }
        else{
            return "It's a lowercase character";
        }
    }
    else{
        return "It's a Number";
    }
}

You can use: Object.keys(obj)

Example:

var dictionary = {
  "cats": [1, 2, 37, 38, 40, 32, 33, 35, 39, 36],
  "dogs": [4, 5, 6, 3, 2]
};

// Get the keys
var keys = Object.keys(dictionary);

console.log(keys);

See reference below for browser support. It is supported in Firefox 4.20, Chrome 5, and Internet Explorer 9. Object.keys() contains a code snippet that you can add if Object.keys() is not supported in your browser.

From what I've heard, video support is minimal at best.

From http://diveintohtml5.ep.io/video.html#what-works:

As of this writing, this is the landscape of HTML5 video:

• Mozilla Firefox (3.5 and later) supports Theora video and Vorbis audio in an Ogg container. Firefox 4 also supports WebM.

• Opera (10.5 and later) supports Theora video and Vorbis audio in an Ogg container. Opera 10.60 also supports WebM.

• Google Chrome (3.0 and later) supports Theora video and Vorbis audio in an Ogg container. Google Chrome 6.0 also supports WebM.

• Safari on Macs and Windows PCs (3.0 and later) will support anything that QuickTime supports. In theory, you could require your users to install third-party QuickTime plugins. In practice, few users are going to do that. So you’re left with the formats that QuickTime supports “out of the box.” This is a long list, but it does not include WebM, Theora, Vorbis, or the Ogg container. However, QuickTime does ship with support for H.264 video (main profile) and AAC audio in an MP4 container.

• Mobile phones like Apple’s iPhone and Google Android phones support H.264 video (baseline profile) and AAC audio (“low complexity” profile) in an MP4 container.

• Adobe Flash (9.0.60.184 and later) supports H.264 video (all profiles) and AAC audio (all profiles) in an MP4 container.

• Internet Explorer 9 supports all profiles of H.264 video and either AAC or MP3 audio in an MP4 container. It will also play WebM video if you install a third-party codec, which is not installed by default on any version of Windows. IE9 does not support other third-party codecs (unlike Safari, which will play anything QuickTime can play).

• Internet Explorer 8 has no HTML5 video support at all, but virtually all Internet Explorer users will have the Adobe Flash plugin. Later in this chapter, I’ll show you how you can use HTML5 video but gracefully fall back to Flash.

As well, you should note this section just below on the same page:

There is no single combination of containers and codecs that works in all HTML5 browsers.

This is not likely to change in the near future.

To make your video watchable across all of these devices and platforms, you’re going to need to encode your video more than once.

Taking Google OAuth as reference

• In your OAuth client Tab

  1. Add your App URI example(http://localhost:3000) to Authorized JavaScript origins URIs

• In your OAuth consent screen

  1. Add mywebsite.com to Authorized domains

• Edit the hosts file on windows or linux Windows C:\Windows\System32\Drivers\etc\hosts Linux : /etc/hosts to add 127.0.0.1 mywebsite.com (N.B. Comment out any if there is any other 127.0.0.1)

I faced a bit of a different issue that returned the same error.

Skipping JaCoCo execution due to missing execution data /target/jacoco.exec

The truth is, this error is returned for many, many reasons. We experimented with the different solutions on Stack Overflow, but found this resource to be best. It tears down the many different potential reasons why Jacoco could be returning the same error.

For us, the solution was to add a prepare-agent to the configuration.

<execution>
   <id>default-prepare-agent</id>
   <goals>
       <goal>prepare-agent</goal>
   </goals>
</execution>

I would imagine most users will be experiencing it for different reasons, so take a look at the aforementioned resource!

    // pop back stack all the way
    final FragmentManager fm = getSherlockActivity().getSupportFragmentManager();
    int entryCount = fm.getBackStackEntryCount(); 
    while (entryCount-- > 0) {
        fm.popBackStack();
    }

The error message you are receiving is telling you that the application failed to connect to the sqlexpress db, and not sql server. I will just change the name of the db in sql server and then update the connectionstring accordingly and try it again.

Your error message states the following:

Cannot open database "Phaeton.mdf" requested by the login. The login failed.

It looks to me you are still trying to connect to the file based database, the name "Phaeton.mdf" does not match with your new sql database name "Phaeton".

Hope this helps.

RobW is right on the first comment. You have to save the file in your IDE with encoding UTF-8. I moved my alert from .js file to my .html file and this solved the issue cause Visual Studio saves .html with UTF-8 encoding.

The difference between an operating system and a kernel:

The kernel is a part of an operating system. The operating system is the software package that communicates directly to the hardware and our application. The kernel is the lowest level of the operating system. The kernel is the main part of the operating system and is responsible for translating the command into something that can be understood by the computer. The main functions of the kernel are:

1. memory management
2. network management
3. device driver
4. file management
5. process management

If you would like to get GMT time only with intiger: var currentTime = new Date(); var currentYear ='2010' var currentMonth = 10; var currentDay ='30' var currentHours ='20' var currentMinutes ='20' var currentSeconds ='00' var currentMilliseconds ='00'

currentTime.setFullYear(currentYear);
currentTime.setMonth((currentMonth-1)); //0is January
currentTime.setDate(currentDay);  
currentTime.setHours(currentHours);
currentTime.setMinutes(currentMinutes);
currentTime.setSeconds(currentSeconds);

According to Flexbugs:

In IE 10-11, min-height declarations on flex containers work to size the containers themselves, but their flex item children do not seem to know the size of their parents. They act as if no height has been set at all.

Here are a couple of workarounds:

1. Always fill the viewport + scrollable <aside> and <section>:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1;
  display: flex;
}

aside, section {
  overflow: auto;
}

aside {
  flex: 0 0 150px;
  background: #3e48cc;
}

section {
  flex: 1;
  background: #9ad9ea;
}

<header>
  <p>header</p>
</header>

<main>
  <aside>
    <p>aside</p>
  </aside>
  <section>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
  </section>
</main>

<footer>
  <p>footer</p>
</footer>

2. Fill the viewport initially + normal page scroll with more content:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1 0 auto;
  display: flex;
}

aside {
  flex: 0 0 150px;
  background: #3e48cc;
}

section {
  flex: 1;
  background: #9ad9ea;
}

<header>
  <p>header</p>
</header>

<main>
  <aside>
    <p>aside</p>
  </aside>
  <section>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>

There can be more than 52 weeks in a year. Each year has 52 full weeks + 1 or +2 (leap year) days extra. They make up for a 53th week.

• 52 weeks * 7days = 364 days.

So for each year you have at least one an extra day. Two for leap years. Are these extra days counted as separate weeks of their own?

How many weeks there are really depends on the starting day of your week. Let's consider this for 2012.

• US (Sunday -> Saturday): 52 weeks + one short 2 day week for 2012-12-30 & 2012-12-31. This results in a total of 53 weeks. Last two days of this year (Sunday + Monday) make up their own short week.

Check your current Culture's settings to see what it uses as the first day of the week.

As you see it's normal to get 53 as a result.

• Europe (Monday -> Sunday): January 2dn (2012-1-2) is the first monday, so this is the first day of the first week. Ask the week number for the 1st of January and you'll get back 52 as it is considered part of 2011 last's week.

It's even possible to have a 54th week. Happens every 28 years when the 1st of January and the 31st of December are treated as separate weeks. It must be a leap year too.

For example, the year 2000 had 54 weeks. January 1st (sat) was the first one week day, and 31st December (sun) was the second one week day.

var d = new DateTime(2012, 12, 31);
CultureInfo cul = CultureInfo.CurrentCulture;

var firstDayWeek = cul.Calendar.GetWeekOfYear(
    d,
    CalendarWeekRule.FirstDay,
    DayOfWeek.Monday);

int weekNum = cul.Calendar.GetWeekOfYear(
    d,
    CalendarWeekRule.FirstDay,
    DayOfWeek.Monday);

int year = weekNum == 52 && d.Month == 1 ? d.Year - 1 : d.Year;
Console.WriteLine("Year: {0} Week: {1}", year, weekNum);

Prints out: Year: 2012 Week: 54

Change CalendarWeekRule in the above example to FirstFullWeek or FirstFourDayWeek and you'll get back 53. Let's keep the start day on Monday since we are dealing with Germany.

So week 53 starts on monday 2012-12-31, lasts one day and then stops.

53 is the correct answer. Change the Culture to germany if want to to try it.

CultureInfo cul = CultureInfo.GetCultureInfo("de-DE");

When You are sending a single quote in a query

empid = " T'via"
empid =escape(empid)

When You get the value including a single quote

var xxx  = request.QueryString("empid")
xxx= unscape(xxx)

If you want to search/ insert the value which includes a single quote in a query xxx=Replace(empid,"'","''")

I realize this has been answered many times, but the following is a decent candidate which can be useful in some scenarios.

it should be noted that it assumes that '.42' is NOT a number, and '4.' is NOT a number, so this should be taken into account.

function isDecimal(x) {
  return '' + x === '' + +x;
}

function isInteger(x) {
  return '' + x === '' + parseInt(x);
}

The isDecimal passes the following test:

function testIsNumber(f) {
  return f('-1') && f('-1.5') && f('0') && f('0.42')
    && !f('.42') && !f('99,999') && !f('0x89f')
    && !f('#abcdef') && !f('1.2.3') && !f('') && !f('blah');
}

The idea here is that every number or integer has one "canonical" string representation, and every non-canonical representation should be rejected. So we cast to a number and back, and see if the result is the original string.

Whether these functions are useful for you depends on the use case. One feature is that distinct strings represent distinct numbers (if both pass the isNumber() test).

This is relevant e.g. for numbers as object property names.

var obj = {};
obj['4'] = 'canonical 4';
obj['04'] = 'alias of 4';
obj[4];  // prints 'canonical 4' to the console.

ok in addition to @user3096626 answer i think it will be more helpful if someone provided code example, the following example will show you how to fix image orientation comes from url (remote images):

Solution 1: using javascript (recommended)

1. because load-image library doesn't extract exif tags from url images only (file/blob), we will use both exif-js and load-image javascript libraries, so first add these libraries to your page as the follow:

   <script src="https://cdnjs.cloudflare.com/ajax/libs/exif-js/2.1.0/exif.min.js"></script>
   <script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image.min.js"></script>
   <script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image-scale.min.js"></script>
   <script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image-orientation.min.js"></script>
   

   Note the version 2.2 of exif-js seems has issues so we used 2.1

2. then basically what we will do is

   a - load the image using window.loadImage()

   b - read exif tags using window.EXIF.getData()

   c - convert the image to canvas and fix the image orientation using window.loadImage.scale()

   d - place the canvas into the document

here you go :)

window.loadImage("/your-image.jpg", function (img) {
  if (img.type === "error") {
    console.log("couldn't load image:", img);
  } else {
    window.EXIF.getData(img, function () {
        var orientation = EXIF.getTag(this, "Orientation");
        var canvas = window.loadImage.scale(img, {orientation: orientation || 0, canvas: true});
        document.getElementById("container").appendChild(canvas); 
        // or using jquery $("#container").append(canvas);

    });
  }
});

of course also you can get the image as base64 from the canvas object and place it in the img src attribute, so using jQuery you can do ;)

$("#my-image").attr("src",canvas.toDataURL());

here is the full code on: github: https://github.com/digital-flowers/loadimage-exif-example

Solution 2: using html (browser hack)

there is a very quick and easy hack, most browsers display the image in the right orientation if the image is opened inside a new tab directly without any html (LOL i don't know why), so basically you can display your image using iframe by putting the iframe src attribute as the image url directly:

<iframe src="/my-image.jpg"></iframe>

Solution 3: using css (only firefox & safari on ios)

there is css3 attribute to fix image orientation but the problem it is only working on firefox and safari/ios it is still worth mention because soon it will be available for all browsers (Browser support info from caniuse)

img {
   image-orientation: from-image;
}

$('#lol').get(0).style.display=''

or..

$('#lol').css('display', '')

Building on Rene's answer, you could also write a function that returned either TRUE if the substring was present, or FALSE if it wasn't:

Public Function Contains(strBaseString As String, strSearchTerm As String) As Boolean
'Purpose: Returns TRUE if one string exists within another
On Error GoTo ErrorMessage
    Contains = InStr(strBaseString, strSearchTerm)
Exit Function
ErrorMessage:
MsgBox "The database has generated an error. Please contact the database administrator, quoting the following error message: '" & Err.Description & "'", vbCritical, "Database Error"
End
End Function

Can use this method in appdelegate file and can use at every view

+(UILabel *) navigationTitleLable:(NSString *)title
{
CGRect frame = CGRectMake(0, 0, 165, 44);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = NAVIGATION_TITLE_LABLE_SIZE;
label.shadowColor = [UIColor whiteColor];
label.numberOfLines = 2;
label.lineBreakMode = UILineBreakModeTailTruncation;    
label.textAlignment = UITextAlignmentCenter;
[label setShadowOffset:CGSizeMake(0,1)]; 
label.textColor = [UIColor colorWithRed:51/255.0 green:51/255.0 blue:51/255.0 alpha:1.0];

//label.text = NSLocalizedString(title, @"");

return label;
}

Fastest way to do this would be:

int count = 0;
for(int i = 0; i < str.length(); i++) {
     if(Character.isWhitespace(str.charAt(i))) count++;
}

This would catch all characters that are considered whitespace.

Regex solutions require compiling regex and excecuting it - with a lot of overhead. Getting character array requires allocation. Iterating over byte array would be faster, but only if you are sure that your characters are ASCII.

The question is answered already, but I want add more information about the causes.

Android app unable to start activity componentinfo

This error often comes with appropriate logs. You can read logs and can solve this issue easily.

Here is a sample log. In which you can see clearly ClassCastException. So this issue came because TextView cannot be cast to EditText.

Some Common Mistakes.

1.findViewById() of non existing view

Like when you use findViewById(R.id.button) when button id does not exist in layout XML.

2. Wrong cast.

If you wrong cast some class, then you get this error. Like you cast RelativeLayout to LinearLayout or EditText to TextView.

3. Activity not registered in manifest.xml

If you did not register Activity in manifest.xml then this error comes.

4. findViewById() with declaration at top level

Below code is incorrect. This will create error. Because you should do findViewById() after calling setContentView(). Because an View can be there after it is created.

public class MainActivity extends Activity {

  ImageView mainImage = (ImageView) findViewById(R.id.imageViewMain); //incorrect way

  @Override
  protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mainImage = (ImageView) findViewById(R.id.imageViewMain); //correct way
    //...
  }
}

5. Starting abstract Activity class.

When you try to start an Activity which is abstract, you will will get this error. So just remove abstract keyword before activity class name.

6. Using kotlin but kotlin not configured.

If your activity is written in Kotlin and you have not setup kotlin in your app. then you will get error. You can follow simple steps as written in Android Link or Kotlin Link. You can check this answer too.

<!DOCTYPE html> without this tag border-radius doesn't works in IE9, no need of meta tags.

You can use

<?php the_category(', '); ?>

which would output them in a comma separated list.

You can also do the same for tags as well:

<?php the_tags('<em>:</em>', ', ', ''); ?>

Mozilla Developer Network has a nice description and example of onbeforeunload.

If you want to warn the user before leaving the page if your page is dirty (i.e. if user has entered some data):

window.addEventListener('beforeunload', function(e) {
  var myPageIsDirty = ...; //you implement this logic...
  if(myPageIsDirty) {
    //following two lines will cause the browser to ask the user if they
    //want to leave. The text of this dialog is controlled by the browser.
    e.preventDefault(); //per the standard
    e.returnValue = ''; //required for Chrome
  }
  //else: user is allowed to leave without a warning dialog
});

Yes, but when argument matching for a reference, the implicit array to pointer isn't automatic, so you need something like:

void foo( double (&array)[42] );

or

void foo( double (&array)[] );

Be aware, however, that when matching, double [42] and double [] are distinct types. If you have an array of an unknown dimension, it will match the second, but not the first, and if you have an array with 42 elements, it will match the first but not the second. (The latter is, IMHO, very counter-intuitive.)

In the second case, you'll also have to pass the dimension, since there's no way to recover it once you're inside the function.

The UUID stands for Universally Unique Identifier. UUID is an simple 128 bit digit which uniquely distributed across the world.

Bluetooth sends data over air and all nearby device can receive it. Let's suppose, sometimes you have to send some important files via Bluetooth and all near by devices can access it in range. So when you pair with the other devices, they simply share the UUID number and match before sharing the files. When you send any file then your device encrypt that file with appropriate device UUID and share over the network. Now all Bluetooth devices in the range can access the encrypt file but they required right UUID number. So Only right UUID devices have access to encrypt the file and others will reject cause of wrong UUID.

In short, you can use UUID as a secret password for sharing files between any two Bluetooth devices.

Since struct instances are allocated on stack, and class instances are allocated on heap, structs can sometimes be drastically faster.

However, you should always measure it yourself and decide based on your unique use case.

Consider the following example, which demonstrates 2 strategies of wrapping Int data type using struct and class. I am using 10 repeated values are to better reflect real world, where you have multiple fields.

class Int10Class {
    let value1, value2, value3, value4, value5, value6, value7, value8, value9, value10: Int
    init(_ val: Int) {
        self.value1 = val
        self.value2 = val
        self.value3 = val
        self.value4 = val
        self.value5 = val
        self.value6 = val
        self.value7 = val
        self.value8 = val
        self.value9 = val
        self.value10 = val
    }
}

struct Int10Struct {
    let value1, value2, value3, value4, value5, value6, value7, value8, value9, value10: Int
    init(_ val: Int) {
        self.value1 = val
        self.value2 = val
        self.value3 = val
        self.value4 = val
        self.value5 = val
        self.value6 = val
        self.value7 = val
        self.value8 = val
        self.value9 = val
        self.value10 = val
    }
}

func + (x: Int10Class, y: Int10Class) -> Int10Class {
    return IntClass(x.value + y.value)
}

func + (x: Int10Struct, y: Int10Struct) -> Int10Struct {
    return IntStruct(x.value + y.value)
}

Performance is measured using

// Measure Int10Class
measure("class (10 fields)") {
    var x = Int10Class(0)
    for _ in 1...10000000 {
        x = x + Int10Class(1)
    }
}

// Measure Int10Struct
measure("struct (10 fields)") {
    var y = Int10Struct(0)
    for _ in 1...10000000 {
        y = y + Int10Struct(1)
    }
}

func measure(name: String, @noescape block: () -> ()) {
    let t0 = CACurrentMediaTime()

    block()

    let dt = CACurrentMediaTime() - t0
    print("\(name) -> \(dt)")
}

UPDATE (27 Mar 2018):

As of Swift 4.0, Xcode 9.2, running Release build on iPhone 6S, iOS 11.2.6, Swift Compiler setting is -O -whole-module-optimization:

• class version took 2.06 seconds
• struct version took 4.17e-08 seconds (50,000,000 times faster)

(I no longer average multiple runs, as variances are very small, under 5%)

Note: the difference is a lot less dramatic without whole module optimization. I'd be glad if someone can point out what the flag actually does.

UPDATE (7 May 2016):

As of Swift 2.2.1, Xcode 7.3, running Release build on iPhone 6S, iOS 9.3.1, averaged over 5 runs, Swift Compiler setting is -O -whole-module-optimization:

• class version took 2.159942142s
• struct version took 5.83E-08s (37,000,000 times faster)

Note: as someone mentioned that in real-world scenarios, there will be likely more than 1 field in a struct, I have added tests for structs/classes with 10 fields instead of 1. Surprisingly, results don't vary much.

ORIGINAL RESULTS (1 June 2014):

(Ran on struct/class with 1 field, not 10)

As of Swift 1.2, Xcode 6.3.2, running Release build on iPhone 5S, iOS 8.3, averaged over 5 runs

• class version took 9.788332333s
• struct version took 0.010532942s (900 times faster)

OLD RESULTS (from unknown time)

(Ran on struct/class with 1 field, not 10)

With release build on my MacBook Pro:

• The class version took 1.10082 sec
• The struct version took 0.02324 sec (50 times faster)

Unfortunately MSTest STILL only really has the ExpectedException attribute (just shows how much MS cares about MSTest) which IMO is pretty awful because it breaks the Arrange/Act/Assert pattern and it doesnt allow you to specify exactly which line of code you expect the exception to occur on.

When I'm using (/forced by a client) to use MSTest I always use this helper class:

public static class AssertException
{
    public static void Throws<TException>(Action action) where TException : Exception
    {
        try
        {
            action();
        }
        catch (Exception ex)
        {
            Assert.IsTrue(ex.GetType() == typeof(TException), "Expected exception of type " + typeof(TException) + " but type of " + ex.GetType() + " was thrown instead.");
            return;
        }
        Assert.Fail("Expected exception of type " + typeof(TException) + " but no exception was thrown.");
    }

    public static void Throws<TException>(Action action, string expectedMessage) where TException : Exception
    {
        try
        {
            action();
        }
        catch (Exception ex)
        {
            Assert.IsTrue(ex.GetType() == typeof(TException), "Expected exception of type " + typeof(TException) + " but type of " + ex.GetType() + " was thrown instead.");
            Assert.AreEqual(expectedMessage, ex.Message, "Expected exception with a message of '" + expectedMessage + "' but exception with message of '" + ex.Message + "' was thrown instead.");
            return;
        }
        Assert.Fail("Expected exception of type " + typeof(TException) + " but no exception was thrown.");
    }
}

Example of usage:

AssertException.Throws<ArgumentNullException>(() => classUnderTest.GetCustomer(null));

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

I wasted hours on this stupid issue. None of the above solutions worked for me on their own.

I'm running Windows 10. I had an old manual install of the Android SDK as well as Android Studio's SDK. I deleted my manually installed SDK and all my devices stopped working. These were the symptoms:

$ adb usb
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.

as well as

$ adb devices
List of devices attached
id1        unauthorized
id2        unauthorized
id3        unauthorized

To be honest I'm not sure which of these steps got me my Allow USB debugging? prompts back so I listed EVERYTHING for completeness. Goes in order from easiest to hardest. Most people seem to be back on their feet after the first two sections.

Restart ADB

I would perform this after each of the sections below.

adb kill-server
adb usb

Go crazy with developer options

1. Turn Developer options off and back on
2. Turn USB debugging off and back on
3. Revoke USB debugging authorizations. Try this while USB debugging is on and if possible try also when USB debugging is off.

Replug devices

1. Unplug and replug USB cable into phone.
2. Switch physical ports on your PC that your USB cable is connected into
3. Switch physical USB cables you're using to connect your devices

Start rebooting everything

1. Reboot all your devices and connect again
2. Reboot your PC
3. Toggle WIFI on and off

Start deleting things

1. CAUTION Delete your ~/.android folder. Sometimes this folder can have the wrong permissions which can cause issues. You might want to back this folder up first.
2. Uninstall all manufacturer specific drivers from add/remove programs. I uninstalled the following (names are not exact)
   • LG United USB Driver
   • HTC Mobile USB Driver
   • OnePlus USB Drivers 1.00
   • Samsung USB Driver
3. I also uninstalled all emulators and their respective drivers (optional)
   • Nox & related drivers
   • Bluestacks
   • Genymotion

Erase all Android related environment variables.

1. Delete %ANDROID_HOME% if you have it set
2. Delete %ANDROID_SDK_HOME% if you have it set

At this point all my devices magically came to life and started displaying the Allow USB debugging? prompts and connecting properly through ADB. If you've made it this far and haven't found a solution, I am truly sorry you're in this predicament. Make sure you've restarted all devices and your dev machine at the end of all of these steps and connect to a fresh USB port using a new cable.

If that still doesn't work try some of these other SO posts on the subject:

• Android ADB device offline, can't issue commands
• Can't connect Nexus 4 to adb: unauthorized
• How to solve ADB device unauthorized in Android ADB host device?

From RFC 4918 (and also documented at http://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml):

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

I met this question too in native and react-native pro, my solution was:

1. open npm server with npm start
2. run native project with Android Studio
3. transmission network request with adb reverse tcp:8081 tcp:8081
4. when you need to reload the page, just input: adb shell input keyevent 82

just keep it in order.

P.S. if you ran a fail project, just run adb kill-server

Publish / Subscribe With jQuery

June 17th, 2008

With a view to writing a jQuery UI integrated with the offline functionality of Google Gears i’ve been toying with some code to poll for network connection status using jQuery.

The Network Detection Object

The basic premise is very simple. We create an instance of a network detection object which will poll a URL at regular intervals. Should these HTTP requests fail we can assume that network connectivity has been lost, or the server is simply unreachable at the current time.

$.networkDetection = function(url,interval){
    var url = url;
    var interval = interval;
    online = false;
    this.StartPolling = function(){
        this.StopPolling();
        this.timer = setInterval(poll, interval);
    };
    this.StopPolling = function(){
        clearInterval(this.timer);
    };
    this.setPollInterval= function(i) {
        interval = i;
    };
    this.getOnlineStatus = function(){
        return online;
    };
    function poll() {
        $.ajax({
            type: "POST",
            url: url,
            dataType: "text",
            error: function(){
                online = false;
                $(document).trigger('status.networkDetection',[false]);
            },
            success: function(){
                online = true;
                $(document).trigger('status.networkDetection',[true]);
            }
        });
    };
};

You can view the demo here. Set your browser to work offline and see what happens…. no, it’s not very exciting.

Trigger and Bind

What is exciting though (or at least what is exciting me) is the method by which the status gets relayed through the application. I’ve stumbled upon a largely un-discussed method of implementing a pub/sub system using jQuery’s trigger and bind methods.

The demo code is more obtuse than it need to be. The network detection object publishes ’status ‘events to the document which actively listens for them and in turn publishes ‘notify’ events to all subscribers (more on those later). The reasoning behind this is that in a real world application there would probably be some more logic controlling when and how the ‘notify’ events are published.

$(document).bind("status.networkDetection", function(e, status){
    // subscribers can be namespaced with multiple classes
    subscribers = $('.subscriber.networkDetection');
    // publish notify.networkDetection even to subscribers
    subscribers.trigger("notify.networkDetection", [status])
    /*
    other logic based on network connectivity could go here
    use google gears offline storage etc
    maybe trigger some other events
    */
});

Because of jQuery’s DOM centric approach events are published to (triggered on) DOM elements. This can be the window or document object for general events or you can generate a jQuery object using a selector. The approach i’ve taken with the demo is to create an almost namespaced approach to defining subscribers.

DOM elements which are to be subscribers are classed simply with “subscriber” and “networkDetection”. We can then publish events only to these elements (of which there is only one in the demo) by triggering a notify event on $(“.subscriber.networkDetection”)

The #notifier div which is part of the .subscriber.networkDetection group of subscribers then has an anonymous function bound to it, effectively acting as a listener.

$('#notifier').bind("notify.networkDetection",function(e, online){
    // the following simply demonstrates
    notifier = $(this);
    if(online){
        if (!notifier.hasClass("online")){
            $(this)
                .addClass("online")
                .removeClass("offline")
                .text("ONLINE");
        }
    }else{
        if (!notifier.hasClass("offline")){
            $(this)
                .addClass("offline")
                .removeClass("online")
                .text("OFFLINE");
        }
    };
});

So, there you go. It’s all pretty verbose and my example isn’t at all exciting. It also doesn’t showcase anything interesting you could do with these methods, but if anyone’s at all interested to dig through the source feel free. All the code is inline in the head of the demo page

You could throw the enum value and string into an STL map. Then you could use it like so.

   return myStringMap[Enum::Apple];

    I used below logic while saving a .png format. This is to ensure the file is already existing or not.. if exist then saving it by adding 1 in the filename

Bitmap btImage = new Bitmap("D:\\Oldfoldername\\filename.png");
    string path="D:\\Newfoldername\\filename.png";
            int Count=0;
                if (System.IO.File.Exists(path))
                {
                    do
                    {
                        path = "D:\\Newfoldername\\filename"+"_"+ ++Count + ".png";                    
                    } while (System.IO.File.Exists(path));
                }

                btImage.Save(path, System.Drawing.Imaging.ImageFormat.Png);

Here is how you can handle this:

    var scrollStop = function (callback) {_x000D_
        if (!callback || typeof callback !== 'function') return;_x000D_
        var isScrolling;_x000D_
        window.addEventListener('scroll', function (event) {_x000D_
            window.clearTimeout(isScrolling);_x000D_
            isScrolling = setTimeout(function() {_x000D_
                callback();_x000D_
            }, 66);_x000D_
        }, false);_x000D_
    };_x000D_
    scrollStop(function () {_x000D_
        console.log('Scrolling has stopped.');_x000D_
    });

I'd like to add my Python3 answer for completeness:

from io import BytesIO
from zipfile import ZipFile
import requests

def get_zip(file_url):
    url = requests.get(file_url)
    zipfile = ZipFile(BytesIO(url.content))
    zip_names = zipfile.namelist()
    if len(zip_names) == 1:
        file_name = zip_names.pop()
        extracted_file = zipfile.open(file_name)
        return extracted_file
    return [zipfile.open(file_name) for file_name in zip_names]

I've also been successful with this URL structure:

Please note that since I've specified a timezone with the "ctz" parameter, I used the local times for the start and end dates. Alternatively, you can use UTC dates and exclude the timezone parameter, like this:

dates=20200222T150000Z/20200222T163000Z

I guess you want to do the "Iterating over Keys and Values"

As the doc here says, just add "|keys" in the variable you want and it will magically happen.

{% for key, user in users %}
    <li>{{ key }}: {{ user.username|e }}</li>
{% endfor %}

It never hurts to search before asking :)

From the Overview tab of jQuery autocomplete plugin:

The local data can be a simple Array of Strings, or it contains Objects for each item in the array, with either a label or value property or both. The label property is displayed in the suggestion menu. The value will be inserted into the input element after the user selected something from the menu. If just one property is specified, it will be used for both, eg. if you provide only value-properties, the value will also be used as the label.

So your "two-dimensional" array could look like:

var $local_source = [{
    value: 1,
    label: "c++"
}, {
    value: 2,
    label: "java"
}, {
    value: 3,
    label: "php"
}, {
    value: 4,
    label: "coldfusion"
}, {
    value: 5,
    label: "javascript"
}, {
    value: 6,
    label: "asp"
}, {
    value: 7,
    label: "ruby"
}];

You can access the label and value properties inside focus and select event through the ui argument using ui.item.label and ui.item.value.

Edit

Seems like you have to "cancel" the focus and select events so that it does not place the id numbers inside the text boxes. While doing so you can copy the value in a hidden variable instead. Here is an example.

In addition to all the other correct answers, since Rails.root is a Pathname object, this won't work:

Rails.root + '/app/assets/...'

You could use something like join

Rails.root.join('app', 'assets')

If you want a string use this:

Rails.root.join('app', 'assets').to_s

AFAIK there is no possibility beside from using keys or expect if you are using the command line version ssh. But there are library bindings for the most programming languages like C, python, php, ... . You could write a program in such a language. This way it would be possible to pass the password automatically. But note this is of course a security problem as the password will be stored in plain text in that program

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

cout is in std namespace, you shall use std::cout in your code. And you shall not add using namespace std; in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.

Does this work?

[0-9]{2}.[0-9]{2}

In a one to many and many to one relationship this error will occur. If you attempt to devote same instance from many to one entity to more than one instance from one to many entity.

For example, each person can have many books but each of these books can be owned by only one person if you consider more than one owner for a book this issue is raised.

I just copied from http://social.msdn.microsoft.com/forums/en-US/Vsexpressvc/thread/1555ce45-8313-4669-a31e-b95b5d28c787/?prof=required:

The following works for me :-)

/////////////////////////////////////////////////////////////////////////////////////

Here is another reason the console may disappear. And the solution:

With the new Visual Studio 2010 you might see this behavior even when you use Ctrl + F5 aka "start without debugging". This is most likely because you created an "empty project" instead of a "Win32 console application". If you create the project as a "Win32 console application" you can disregard this as it does not apply.

In the older versions it would default to the console subsystem even if you selected "empty project", but not in Visual Studio 2010, so you have to set it manually. To do this select the project in the solution explorer on the right or left (probably is already selected so you don't have to worry about this).

Then select "project" from the menu bar drop down menus, then select "project_name properties" ? "configuration properties" ? "linker" ? "system" and set the first property, the drop down "subsystem" property to "console (/SUBSYSTEM:CONSOLE)". The console window should now stay open after execution as usual.

/////////////////////////////////////////////////////////////////////////////////////

dev.off() is the best function, but it clears also all plots. If you want to keep plots in your window, at the beginning save default par settings:

def.par = par()

Then when you use your par functions you still have a backup of default par settings. Later on, after generating plots, finish with:

par(def.par) #go back to default par settings

With this, you keep generated plots and reset par settings.

IMO this link from Yochai Timmer was very good and relevant but painful to read. I wrote a summary.

Yochai, if you ever read this, please see the note at the end.

For the original post read : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs

Error

LINK : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs; use /NODEFAULTLIB:library

Meaning

one part of the system was compiled to use a single threaded standard (libc) library with debug information (libcd) which is statically linked

while another part of the system was compiled to use a multi-threaded standard library without debug information which resides in a DLL and uses dynamic linking

How to resolve

• Ignore the warning, after all it is only a warning. However, your program now contains multiple instances of the same functions.

• Use the linker option /NODEFAULTLIB:lib. This is not a complete solution, even if you can get your program to link this way you are ignoring a warning sign: the code has been compiled for different environments, some of your code may be compiled for a single threaded model while other code is multi-threaded.

• [...] trawl through all your libraries and ensure they have the correct link settings

In the latter, as it in mentioned in the original post, two common problems can arise :

• You have a third party library which is linked differently to your application.

• You have other directives embedded in your code: normally this is the MFC. If any modules in your system link against MFC all your modules must nominally link against the same version of MFC.

For those cases, ensure you understand the problem and decide among the solutions.

Note : I wanted to include that summary of Yochai Timmer's link into his own answer but since some people have trouble to review edits properly I had to write it in a separate answer. Sorry

During an interview, I was asked to reverse a string without using any variables or native methods. This is my favorite implementation:

function reverseString(str) {
    return str === '' ? '' : reverseString(str.slice(1)) + str[0];
}

As you're using Windows, installation should automatically edit the %PATH% variable. Therefore, I suspect you simply need to reboot your system after installing.

I think the best way to add comments to a CSV file would be to add a "Comments" field or record right into the data.

Most CSV-parsing applications that I've used implement both field-mapping and record-choosing. So, to comment on the properties of a field, add a record just for field descriptions. To comment on a record, add a field at the end of it (well, all records, really) just for comments.

These are the only two reasons I can think of to comment a CSV file. But the only problem I can foresee would be programs that refuse to accept the file at all if any single record doesn't pass some validation rules. In that case, you'd have trouble writing a string-type field description record for any numeric fields.

I am by no means an expert, though, so feel free to point out any mistakes in my theory.

<style type="text/css">
>> .imgTop {
>>  display: block;
>>  text-align: right;
>>  }
>> </style>

<img class="imgTop" src="imgName.gif" alt="image description" height="100" width="100">

You can install and use the pip-autoremove utility to remove a package plus unused dependencies.

# install pip-autoremove
pip install pip-autoremove
# remove "somepackage" plus its dependencies:
pip-autoremove somepackage -y

a=int(input('enter any number'))
flag=0
for i in range(1,a):
    if a==i*i:
        print(a,'is perfect square number')
        flag=1
        break
if flag==1:
    pass
else:
    print(a,'is not perfect square number')

The solution from CSS-Tricks no longer works in jQuery 2.2.0. It will throw a selector error:

JavaScript runtime error: Syntax error, unrecognized expression: a[href*=#]:not([href=#])

I fixed it by changing the selector. The full snippet is this:

$(function() {
  $("a[href*='#']:not([href='#'])").click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
    var target = $(this.hash);
    target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
    if (target.length) {
      $('html,body').animate({
        scrollTop: target.offset().top
      }, 1000);
      return false;
    }
  }
 });
});

Take a look into NSColorWell class reference.

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

$ sudo yum install subversion

Putting this http://www.mredkj.com/javascript/numberFormat.html and $('.number').formatNumber(); concept together, you may use the following line of code;

e.g. <td class="number">1172907.50</td> will be formatted like <td class="number">1,172,907.50</td>

$('.number').text(function () { 
    var str = $(this).html() + ''; 
    x = str.split('.'); 
    x1 = x[0]; x2 = x.length > 1 ? '.' + x[1] : ''; 
    var rgx = /(\d+)(\d{3})/; 
    while (rgx.test(x1)) { 
        x1 = x1.replace(rgx, '$1' + ',' + '$2'); 
    } 
    $(this).html(x1 + x2); 
});

had better be List

The only List implementation in java.util.concurrent is CopyOnWriteArrayList. There's also the option of a synchronized list as Travis Webb mentions.

That said, are you sure you need it to be a List? There are a lot more options for concurrent Queues and Maps (and you can make Sets from Maps), and those structures tend to make the most sense for many of the types of things you want to do with a shared data structure.

For queues, you have a huge number of options and which is most appropriate depends on how you need to use it:

• ConcurrentLinkedQueue
• ArrayBlockingQueue
• LinkedBlockingDeque
• LinkedBlockingQueue
• PriorityBlockingQueue
• SynchronousQueue
• DelayQueue

Try this:

Sub GetColumns()

Dim lnRow As Long, lnCol As Long

lnRow = 3 'For testing

lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column

End Sub

Probably best not to use colIndex and rowIndex as variable names as they are already mentioned in the Excel Object Library.

You can figure out version of Cocoapods by using below command :

pod —-version

o/p : 1.2.1

Now if you want detailed version of Gems and Cocoapods then use below command :

gem which cocoapods (without sudo)

o/p : /Library/Ruby/Gems/2.0.0/gems/cocoapods-1.2.1/lib/cocoapods.rb

sudo gem which cocoapods (with sudo)

o/p : /Library/Ruby/Gems/2.0.0/gems/cocoapods-1.2.1/lib/cocoapods.rb

Now if you want to get specific version of Pod present in Podfile then simply use command pod install in terminal. This will show list of pod being used in project along with version.

String allocates dynamic memory size in the heap of your RAM. But string address is stored in stack that occupies 4 bytes of memory.

Numpy's r_ convenience function can also create evenly spaced lists with syntax np.r_[start:stop:steps]. If steps is a real number (ending on j), then the end point is included, equivalent to np.linspace(start, stop, step, endpoint=1), otherwise not.

>>> np.r_[-1:1:6j, [0]*3, 5, 6]
array([-1. , -0.6, -0.2,  0.2,  0.6,  1.])

You can also directly concatente other arrays and also scalars:

>>> np.r_[-1:1:6j, [0]*3, 5, 6]
array([-1. , -0.6, -0.2,  0.2,  0.6,  1. ,  0. ,  0. ,  0. ,  5. ,  6. ])

The following seems pretty natural to me, using Haskell. Iterate recursively over levels of the tree (here I collect names into a big ordered string to show the path through the tree):

data Node = Node {name :: String, children :: [Node]}
aTree = Node "r" [Node "c1" [Node "gc1" [Node "ggc1" []], Node "gc2" []] , Node "c2" [Node "gc3" []], Node "c3" [] ]
breadthFirstOrder x = levelRecurser [x]
    where levelRecurser level = if length level == 0
                                then ""
                                else concat [name node ++ " " | node <- level] ++ levelRecurser (concat [children node | node <- level])

There's the % sign. It's not just for the remainder, it is the modulo operation.

Try this:

jsonResponse = json.loads(response.decode('utf-8'))

"I have int i = 6; and I want char c = '6' by conversion. Any simple way to suggest?"

There are only 10 numbers. So write a function that takes an int from 0-9 and returns the ascii code. Just look it up in an ascii table and write a function with ifs or a select case.

Adding base graphics version that takes care of y-axis limits, add colors and works for any number of columns:

If we have a data set:

myData <- data.frame(std.nromal=rnorm(1000, m=0, sd=1),
                     wide.normal=rnorm(1000, m=0, sd=2),
                     exponent=rexp(1000, rate=1),
                     uniform=runif(1000, min=-3, max=3)
                     )

Then to plot the densities:

dens <- apply(myData, 2, density)

plot(NA, xlim=range(sapply(dens, "[", "x")), ylim=range(sapply(dens, "[", "y")))
mapply(lines, dens, col=1:length(dens))

legend("topright", legend=names(dens), fill=1:length(dens))

Which gives:

You can simply create a contained user in SQL DB V12.

Create user containeduser with password = 'Password'

Contained user login is more efficient than login to the database using the login created by master. You can find more details @ http://www.sqlindepth.com/contained-users-in-sql-azure-db-v12/

When git stash -p (or git add -p with stash --keep-index) would be too cumbersome, I found it easier to use diff, checkout and apply:

To "stash" a particular file/dir only:

git diff path/to/dir > stashed.diff
git checkout path/to/dir

Then afterwards

git apply stashed.diff

you can definitely make such application, you need to make http conection to the database, by calling a php script which will in response run specific queries according to your project, and generated the result in the form of xml, or json formate , whihc can be displayed on your android application!. for complete tutorial on how to connect android application to mysql i would recommend to check out this tutorila

cd /home/<user_name>/
sudo vi .bash_profile

add these lines at the end

LD_LIBRARY_PATH=/usr/local/lib:<any other paths you want>
export LD_LIBRARY_PATH

Ultimately was able to figure it out , i just hope it will help someone like me.
Following is how the web pack config file should look like check the dist dir and output file specified. I was missing the way to specify the path of dist directory

const webpack = require('webpack');
const path = require('path');
var config = {
    entry: './main.js',

    output: {
        path: path.join(__dirname, '/dist'),
        filename: 'index.js',
    },

    devServer: {
        inline: true,
        port: 8080
    },
    resolveLoader: {
        modules: [path.join(__dirname, 'node_modules')]
    },
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loader: 'babel-loader',

                query: {
                    presets: ['es2015', 'react']
                }
            }
        ]
    },
}

module.exports = config;

Then the package json file

{
  "name": "reactapp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack --progress",
    "production": "webpack -p --progress"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2",
    "webpack": "^2.2.1"
  },
  "devDependencies": {
    "babel-core": "^6.0.20",
    "babel-loader": "^6.0.1",
    "babel-preset-es2015": "^6.0.15",
    "babel-preset-react": "^6.0.15",
    "babel-preset-stage-0": "^6.0.15",
    "express": "^4.13.3",
    "webpack": "^1.9.6",
    "webpack-devserver": "0.0.6"
  }
}

Notice the script section and production section, production section is what gives you the final deployable index.js file ( name can be anything )

Rest fot the things will depend upon your code and components

Execute following sequence of commands

npm install

this should get you all the dependency (node modules)

then

npm run production

this should get you the final index.js file which will contain all the code bundled

Once done place index.html and index.js files under www/html or the web app root directory and that's all.

To check if a directory named "Folder" exists use:

QDir("Folder").exists();

To create a new folder named "MyFolder" use:

QDir().mkdir("MyFolder");

Swift 3 and Swift 4

This is how you can draw a gray line at the end of your view (same idea as b123400's answer)

class CustomView: UIView {

    override func draw(_ rect: CGRect) {
        super.draw(rect)
        
        if let context = UIGraphicsGetCurrentContext() {
            context.setStrokeColor(UIColor.gray.cgColor)
            context.setLineWidth(1)
            context.move(to: CGPoint(x: 0, y: bounds.height))
            context.addLine(to: CGPoint(x: bounds.width, y: bounds.height))
            context.strokePath()
        }
    }
}

These solutions didn't work with my datagrid. I was hoping they would. I don't really need Tab or Enter to move to the next input, column, row or whatever. I just need Enter to trigger .focusout or .change and my datagrid updates the database. So I added the "enter" class to the relevant text inputs and this did the trick for me:

$(function() {
   if ($.browser.mozilla) {
        $(".enter").keypress(checkForEnter);
    } else {
        $(".enter").keydown(checkForEnter);
    }
});

function checkForEnter(event) {
    if (event.keyCode == 13) {
        $(".enter").blur();
    }
}

If what you need is UPDATE from SELECT statement you can do something like this:

UPDATE suppliers    
SET city = (SELECT customers.city FROM customers

WHERE customers.customer_name = suppliers.supplier_name)

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

This is the solution:

• Go to your file Home.js
• Make sure you export your file like this in the end of the file:

export default Home;

I figured this one out. I know this will help someone someday.

How to Vertically & Horizontally Center a Div Over a Relatively Positioned Image

The key was a 3rd wrapper. I would vote up any answer that uses less wrappers.

You can see the working jsFiddle here.

As the name suggests 'untracked files' are the files which are not being tracked by git. They are not in your staging area, and were not part of any previous commits. If you want them to be versioned (or to be managed by git) you can do so by telling 'git' by using 'git add'. Check this chapter Recording Changes to the Repository in the Progit book which uses a nice visual to provide a good explanation about recording changes to git repo and also explaining the terms 'tracked' and 'untracked'.

A much simpler solution:

<script language="javascript" src="http://maps.google.com/maps/api/js?v=3.2&sensor=false"></script>

and later in the code:

var online;
// check whether this function works (online only)
try {
  var x = google.maps.MapTypeId.TERRAIN;
  online = true;
} catch (e) {
  online = false;
}
console.log(online);

When not online the google script will not be loaded thus resulting in an error where an exception will be thrown.

If we want to open multiple command prompts then we could use

start cmd /k

/k: is compulsory which will execute.

Launching many command prompts can be done as below.

start cmd /k Call rc_hub.bat 4444

start cmd /k Call rc_grid1.bat 5555

start cmd /k Call rc_grid1.bat 6666

start cmd /k Call rc_grid1.bat 5570.

You can use any:

a_string = "A string is more than its parts!"
matches = ["more", "wholesome", "milk"]

if any(x in a_string for x in matches):

Similarly to check if all the strings from the list are found, use all instead of any.

For Kotlin.

 notificationManager.notify(Calendar.getInstance().timeInMillis.toInt(),notificationBuilder.build())

CoolAJ86's solution is correct and it does not compromise your security like disabling all checks using rejectUnauthorized or NODE_TLS_REJECT_UNAUTHORIZED. Still, you may need to inject an additional CA's certificate explicitly.

I tried first the root CAs included by the ssl-root-cas module:

require('ssl-root-cas/latest')
  .inject();

I still ended up with the UNABLE_TO_VERIFY_LEAF_SIGNATURE error. Then I found out who issued the certificate for the web site I was connecting to by the COMODO SSL Analyzer, downloaded the certificate of that authority and tried to add only that one:

require('ssl-root-cas/latest')
  .addFile(__dirname + '/comodohigh-assurancesecureserverca.crt');

I ended up with another error: CERT_UNTRUSTED. Finally, I injected the additional root CAs and included "my" (apparently intermediary) CA, which worked:

require('ssl-root-cas/latest')
  .inject()
  .addFile(__dirname + '/comodohigh-assurancesecureserverca.crt');

Just add your text between the font tags:

for blue color

<string name="hello_world"><font color='blue'>Hello world!</font></string>

or for red color

<string name="hello_world"><font color='red'>Hello world!</font></string>

Just look at the docs:

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1"

if you want to use signalr you haveto add startup.cs Class in your project

Right Click In You Project Then Add New Item And Select OWIN Startup Class

then inside Configuration Method Add Code Below

app.MapSignalR();

I Hope it will be useful for you

Stateless means the state of the service doesn’t persist between subsequent requests and response. Each request carries its own user credentials and is individually authenticated. But in stateful each request is known from any prior request. All stateful requests are session-oriented i.e. each request need to know and retain changes made in previous requests.

Banking application is an example of stateful application. Where user first login then make transaction and logs out. If after logout user will try to make the transaction, he will not be able to do so.

Yes, http protocol is essentially a stateless protocol but to make it stateful we make us of HTTP cookies. So, is SOAP by default. But it can be make stateful likewise, depends upon framework you are using.

HTTP is stateless but still we can maintain session in our java application by using different session tracking mechanism.

Yes, We can also maintain session in webservice whether it is REST or SOAP. It can be implemented by using any third party library or you can implement by our own.

Taken from http://gopaldas.org/webservices/soap/webservice-is-stateful-or-stateless-rest-soap

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

In case of Include Program will not terminate and display warning on browser,On the other hand Require program will terminate and display fatal error in case of file not found.

You can't, Doctrine 2 doesn't allow for raw queries. It may seem like you can but if you try something like this:

$sql = "SELECT DATE_FORMAT(whatever.createdAt, '%Y-%m-%d') FORM whatever...";
$em = $this->getDoctrine()->getManager();
$em->getConnection()->exec($sql);

Doctrine will spit an error saying that DATE_FORMAT is an unknown function.

But my database (mysql) does know that function, so basically what is hapening is Doctrine is parsing that query behind the scenes (and behind your back) and finding an expression that it doesn't understand, considering the query to be invalid.

So if like me you want to be able to simply send a string to the database and let it deal with it (and let the developer take full responsibility for security), forget it.

Of course you could code an extension to allow that in some way or another, but you just as well off using mysqli to do it and leave Doctrine to it's ORM buisness.

I would like to add my little contribution to this post:

Doing some testing with a Raspberry Pi 3B+ (I'm using an overlay file system, and need to sync periodically), I ran a comparison of my own for diff -q and cmp -s; note that this is a log from inside /dev/shm, so disk access speeds are a non-issue:

[root@mypi shm]# dd if=/dev/urandom of=test.file bs=1M count=100 ; time diff -q test.file test.copy && echo diff true || echo diff false ; time cmp -s test.file test.copy && echo cmp true || echo cmp false ; cp -a test.file test.copy ; time diff -q test.file test.copy && echo diff true || echo diff false; time cmp -s test.file test.copy && echo cmp true || echo cmp false

I ran it a couple of times. cmp -s consistently had slightly shorter times on the test box I was using. So if you want to use cmp -s to do things between two files....

identical (){
  echo "$1" and "$2" are the same.
  echo This is a function, you can put whatever you want in here.
}
different () {
  echo "$1" and "$2" are different.
  echo This is a function, you can put whatever you want in here, too.
}
cmp -s "$FILEA" "$FILEB" && identical "$FILEA" "$FILEB" || different "$FILEA" "$FILEB"

Why none of you use this?

 ''.join(filter(str.isalnum, s)) 

Too slow?

I'd like to add implementation of Service from Marc Gravell's answer for case of using ServiceClient instead of ChannelFactory.

public interface IServiceConnector<out TServiceInterface>
{
    void Connect(Action<TServiceInterface> clientUsage);
    TResult Connect<TResult>(Func<TServiceInterface, TResult> channelUsage);
}

internal class ServiceConnector<TService, TServiceInterface> : IServiceConnector<TServiceInterface>
    where TServiceInterface : class where TService : ClientBase<TServiceInterface>, TServiceInterface, new()
{
    public TResult Connect<TResult>(Func<TServiceInterface, TResult> channelUsage)
    {
        var result = default(TResult);
        Connect(channel =>
        {
            result = channelUsage(channel);
        });
        return result;
    }

    public void Connect(Action<TServiceInterface> clientUsage)
    {
        if (clientUsage == null)
        {
            throw new ArgumentNullException("clientUsage");
        }
        var isChanneldClosed = false;
        var client = new TService();
        try
        {
            clientUsage(client);
            client.Close();
            isChanneldClosed = true;
        }
        finally
        {
            if (!isChanneldClosed)
            {
                client.Abort();
            }
        }
    }
}

The following solution works for ASP.NET 5 (vNext) and it uses QueryHelpers class to build a URI with parameters.

    public Uri GetUri()
    {
        var location = _config.Get("http://iberia.com");
        Dictionary<string, string> values = GetDictionaryParameters();

        var uri = Microsoft.AspNetCore.WebUtilities.QueryHelpers.AddQueryString(location, values);
        return new Uri(uri);
    }

    private Dictionary<string,string> GetDictionaryParameters()
    {
        Dictionary<string, string> values = new Dictionary<string, string>
        {
            { "param1", "value1" },
            { "param2", "value2"},
            { "param3", "value3"}
        };
        return values;
    }

The result URI would have http://iberia.com?param1=value1&param2=value2&param3=value3

var sal = $('.selectSal option:selected').eq(0).val();

selectSal is a class.

I have managed to achieve this using this XML code only. It might be the case that eclipse does not render the height to show it expanding to fit; however, when you actually run this on a device, it properly renders and provides the desired result. (well at least for me)

<FrameLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content">

     <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:adjustViewBounds="true"
          android:scaleType="centerCrop"
          android:src="@drawable/whatever" />
</FrameLayout>

I created a working CodePen example demonstrating how to do this the correct way in AngularJS. The Angular $window service should be used to access any global objects since directly accessing window makes testing more difficult.

HTML:

<section ng-app="myapp" ng-controller="MainCtrl">
  Value of global variable read by AngularJS: {{variable1}}
</section>

JavaScript:

// global variable outside angular
var variable1 = true;

var app = angular.module('myapp', []);

app.controller('MainCtrl', ['$scope', '$window', function($scope, $window) {
  $scope.variable1 = $window.variable1;
}]);

The best solution is the word-spacing property.

Add the <p> in a container with a specific size (example 300px) and after you have to add that size as the value in the word-spacing.

HTML

<div>
 <p>Sentence Here</p>
</div>

CSS

div {
 width: 300px;
}

p {
 width: auto;
 text-align: center;
 word-spacing: 300px;
}

In this way, your sentence will be always broken and set in a column, but the with of the paragraph will be dynamic.

Here an example Codepen

As per your requirement, Thread.Sleep is perfectly fine to use because you are not sure when the data will be available so you might need to wait for the data to become available. I have slightly changed the logic of your function this might help you little further.

string SendCmd(string cmd, string ip, int port)
{
    var client = new TcpClient(ip, port);
    var data = Encoding.GetEncoding(1252).GetBytes(cmd);
    var stm = client.GetStream();
    stm.Write(data, 0, data.Length);
    byte[] resp = new byte[2048];
    var memStream = new MemoryStream();

    int bytes = 0;

    do
    {
        bytes = 0;
        while (!stm.DataAvailable)
            Thread.Sleep(20); // some delay
        bytes = stm.Read(resp, 0, resp.Length);
        memStream.Write(resp, 0, bytes);
    } 
    while (bytes > 0);

    return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

Hope this helps!

If you are using Modernizr, you can add a custom test for it.

It doesn't matter which detection mode you decide to use (userAgent, navigator.vendor or navigator.platform), you can always wrap it up for a easier use later.

//Add Modernizr test
Modernizr.addTest('isios', function() {
    return navigator.userAgent.match(/(iPad|iPhone|iPod)/g);
});

//usage
if (Modernizr.isios) {
    //this adds ios class to body
    Modernizr.prefixed('ios');
} else {
    //this adds notios class to body
    Modernizr.prefixed('notios');
}

I had the same problem on Win 7. The solution was to remove following files:

1. .hg/store/phaseroots
2. .hg/wlock

As for .hg/store/lock - there was no such file.

2.0 Compatible Answer: While above mentioned answer explain in detail on how to use GPU on Keras Model, I want to explain how it can be done for Tensorflow Version 2.0.

To know how many GPUs are available, we can use the below code:

print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

To find out which devices your operations and tensors are assigned to, put tf.debugging.set_log_device_placement(True) as the first statement of your program.

Enabling device placement logging causes any Tensor allocations or operations to be printed. For example, running the below code:

tf.debugging.set_log_device_placement(True)

# Create some tensors
a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
c = tf.matmul(a, b)

print(c)

gives the Output shown below:

Executing op MatMul in device /job:localhost/replica:0/task:0/device:GPU:0 tf.Tensor( [[22. 28.] [49. 64.]], shape=(2, 2), dtype=float32)

SQL Server doesn't support the SQL standard interval data type. Your best bet is to calculate the difference in seconds, and use a function to format the result. The native function CONVERT() might appear to work fine as long as your interval is less than 24 hours. But CONVERT() isn't a good solution for this.

create table test (
  id integer not null,
  ts datetime not null
  );

insert into test values (1, '2012-01-01 08:00');
insert into test values (1, '2012-01-01 09:00');
insert into test values (1, '2012-01-01 08:30');
insert into test values (2, '2012-01-01 08:30');
insert into test values (2, '2012-01-01 10:30');
insert into test values (2, '2012-01-01 09:00');
insert into test values (3, '2012-01-01 09:00');
insert into test values (3, '2012-01-02 12:00');

Values were chosen in such a way that for

• id = 1, elapsed time is 1 hour
• id = 2, elapsed time is 2 hours, and
• id = 3, elapsed time is 3 hours.

This SELECT statement includes one column that calculates seconds, and one that uses CONVERT() with subtraction.

select t.id,
       min(ts) start_time,
       max(ts) end_time,
       datediff(second, min(ts),max(ts)) elapsed_sec,
       convert(varchar, max(ts) - min(ts), 108) do_not_use
from test t
group by t.id;

ID  START_TIME                 END_TIME                   ELAPSED_SEC  DO_NOT_USE
1   January, 01 2012 08:00:00  January, 01 2012 09:00:00  3600         01:00:00
2   January, 01 2012 08:30:00  January, 01 2012 10:30:00  7200         02:00:00
3   January, 01 2012 09:00:00  January, 02 2012 12:00:00  97200        03:00:00

Note the misleading "03:00:00" for the 27-hour difference on id number 3.

Function to format elapsed time in SQL Server

This do not fully address the OP question but I though it may be useful to some coming here to search for nested structure regexp:

Parse parmeters from function string (with nested structures) in javascript

Match structures like:

• matches brackets, square brackets, parentheses, single and double quotes

Here you can see generated regexp in action

/**
 * get param content of function string.
 * only params string should be provided without parentheses
 * WORK even if some/all params are not set
 * @return [param1, param2, param3]
 */
exports.getParamsSAFE = (str, nbParams = 3) => {
    const nextParamReg = /^\s*((?:(?:['"([{](?:[^'"()[\]{}]*?|['"([{](?:[^'"()[\]{}]*?|['"([{][^'"()[\]{}]*?['")}\]])*?['")}\]])*?['")}\]])|[^,])*?)\s*(?:,|$)/;
    const params = [];
    while (str.length) { // this is to avoid a BIG performance issue in javascript regexp engine
        str = str.replace(nextParamReg, (full, p1) => {
            params.push(p1);
            return '';
        });
    }
    return params;
};

$('#navigation ul li').css({'display' : 'inline-block'});

It seems a typo there ...syntax mistake :))

Look into this one ... call from anywhere you want.

public String setdoubleQuote(String myText) {
    String quoteText = "";
    if (!myText.isEmpty()) {
        quoteText = "\"" + myText + "\"";
    }
    return quoteText;
}

apply double quotes to non empty dynamic string. Hope this is helpful.

A way for easy reading is...

//Remove milliseconds
DateTime date = DateTime.Now;
date = DateTime.ParseExact(date.ToString("yyyy-MM-dd HH:mm:ss"), "yyyy-MM-dd HH:mm:ss", null);

And more...

//Remove seconds
DateTime date = DateTime.Now;
date = DateTime.ParseExact(date.ToString("yyyy-MM-dd HH:mm"), "yyyy-MM-dd HH:mm", null);

//Remove minutes
DateTime date = DateTime.Now;
date = DateTime.ParseExact(date.ToString("yyyy-MM-dd HH"), "yyyy-MM-dd HH", null);

//and go on...

paste your .html file in assets folder of your project folder. and create an xml file in layout folder with the fol code: my.xml:

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/webview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
    />

add fol code in activity

setContentView(R.layout.my);
    WebView mWebView = null;
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.loadUrl("file:///android_asset/new.html"); //new.html is html file name.

You should use the new lightweight View Space to draw dividers. Your layout will load faster if you will use Space instead of View.

Horizontal divider:

<android.support.v4.widget.Space
        android:layout_height="1dp"
        android:layout_width="match_parent" /> 

Vertical divider:

<android.support.v4.widget.Space
        android:layout_height="match_parent"
        android:layout_width="1dp" />

You can also add a background:

<android.support.v4.widget.Space
        android:layout_height="match_parent"
        android:layout_width="1dp"
        android:background="?android:attr/listDivider"/>

Usage example:

....
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="One"/>

<android.support.v4.widget.Space
    android:layout_height="match_parent"
    android:layout_width="1dp"
    android:background="?android:attr/listDivider"/>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Two"/>

<android.support.v4.widget.Space
    android:layout_height="match_parent"
    android:layout_width="1dp"
    android:background="?android:attr/listDivider"/>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Three"/>
....

In order to use Space you should add the dependency in your build.gradle:

dependencies {
    compile 'com.android.support:support-v4:22.1.+'
}

Documentation https://developer.android.com/reference/android/support/v4/widget/Space.html

you can't force refresh but you can forward all old ip requests to new one. for a website:

replace [OLD_IP] with old server's ip

replace [NEW_IP] with new server's ip

run & win.

echo "1" > /proc/sys/net/ipv4/ip_forward

iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 80 -j DNAT --to-destination [NEW_IP]:80

iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 443 -j DNAT --to-destination [NEW_IP]:443

iptables -t nat -A POSTROUTING -j MASQUERADE

Its a new operator for combined comparison. Similar to strcmp() or version_compare() in behavior, but it can be used on all generic PHP values with the same semantics as <, <=, ==, >=, >. It returns 0 if both operands are equal, 1 if the left is greater, and -1 if the right is greater. It uses exactly the same comparison rules as used by our existing comparison operators: <, <=, ==, >= and >.

One way is to run the program in a subshell, and communicate with the subshell through a named pipe with the read command. This way you can check the exit status of the process being run and communicate this back through the pipe.

Here's an example of timing out the yes command after 3 seconds. It gets the PID of the process using pgrep (possibly only works on Linux). There is also some problem with using a pipe in that a process opening a pipe for read will hang until it is also opened for write, and vice versa. So to prevent the read command hanging, I've "wedged" open the pipe for read with a background subshell. (Another way to prevent a freeze to open the pipe read-write, i.e. read -t 5 <>finished.pipe - however, that also may not work except with Linux.)

rm -f finished.pipe
mkfifo finished.pipe

{ yes >/dev/null; echo finished >finished.pipe ; } &
SUBSHELL=$!

# Get command PID
while : ; do
    PID=$( pgrep -P $SUBSHELL yes )
    test "$PID" = "" || break
    sleep 1
done

# Open pipe for writing
{ exec 4>finished.pipe ; while : ; do sleep 1000; done } &  

read -t 3 FINISHED <finished.pipe

if [ "$FINISHED" = finished ] ; then
  echo 'Subprocess finished'
else
  echo 'Subprocess timed out'
  kill $PID
fi

rm finished.pipe
