It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

You can refer this one too, I have written step by step procedure of Manual Crash Re-Symbolication.

Crash Re-Symbolication

STEP 1

Move all the above files (MyApp.app, MyApp-dSYM.dSYM and MyApp-Crash-log.crash) into a Folder with a convenient name wherever you can go using Terminal easily.

For me, Desktop is the most easily reachable place ;) So, I have moved these three files into a folder MyApp at Desktop.

STEP 2

Now its turn of Finder, Go to the path from following whichever is applicable for your XCODE version.

Use this command to find the symbolicatecrash script file,
find /Applications/Xcode.app -name symbolicatecrash

Xcode 8, Xcode 9, Xcode 11 /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash

Xcode 7.3 /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash

XCode 7 /Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash

Xcode 6 /Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources

Lower then Xcode 6 Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKitBase.framework/Versions/A/Resources

Or Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources

STEP 3

Add the found symbolicatecrash script file's directory to $PATH env variable like this: sudo vim /etc/paths.d/Xcode-symbolicatecrash and paste the script file's directory and save the file. When opening a new terminal, you can call symbolicatecrash at any folder as commands located in /usr/bin.

Or

Copy symbolicatecrash file from this location, and paste it to the Desktop/MyApp (Wait… Don’t blindly follow me, I am pasting sybolicatecrash file in folder MyApp, one that you created in step one at your favorite location, having three files.)

STEP 4

Open Terminal, and CD to the MyApp Folder.

cd Desktop/MyApp — Press Enter
export DEVELOPER_DIR=$(xcode-select --print-path)

— Press Enter

./symbolicatecrash -v MyApp-Crash-log.crash MyApp.dSYM

— Press Enter

That’s it !! Symbolicated logs are on your terminal… now what are you waiting for? Now simply, Find out the Error and resolve it ;)

Happy Coding !!!

What solved it for me was setting Build Active Architecture Only from No to Yes.

After searching a few times in google, i found one software for provisioning profiles.

Install this iPhone configuration utility software and manage your all provisioning profiles in MAC.

Select active scheme to Generic iOs Device.

For iTunes 11:

1. open your iTunes "Side Bar" by going to View -> Show Side Bar
2. drag the mobileprovision and ipa files to your iTunes "Apps" under LIBRARY
3. open you device Apps from DEVICES and click install for the application and wait for iTunes to sync

Checked with Mac OS High Sierra and Xcode 10

You can simply implement the same using the application iResign.

Give path of 1).ipa

2) New provision profile

3) Entitlement file (Optional, add only if you have entitlement)

4) Bundle id

5) Distribution Certificate

You can see output .ipa file saved after re-sign

Simple and powerful tool

Make sure your certificate is in the "login" keychain. Highlight the login keychain if you don't see it, search for it. Then drag the cert over the words "login". Close and re-open Xcode, ta-da.

These instructions are for XCode 6.4 (since I couldn't find the update for the recent versions even this was a bit outdated)

a) Part on the developers' website:

Sign in into: https://developer.apple.com/

Member Center

Certificates, Identifiers & Profiles

Certificates>All

Click "+" to add, and then follow the instructions. You will need to open "Keychain Access.app", there under "Keychain Access" menu > "Certificate Assistant>", choose "Request a Certificate From a Certificate Authority" etc.

b) XCode part:

After all, you need to go to XCode, and open XCode>Preferences..., choose your Apple ID > View Details... > click that rounded arrow to update as well as "+" to check for iOS Distribution or iOS Developer Signing Identities.

Improving on Vincent's answer, I wrote a script to do that: xcodearchive
It allows you to archive (generate an ipa) your project via the command line. Think of it like the sister of the xcodebuild command, but for archiving.

Code is available on github: http://github.com/gcerquant/xcodearchive

One option of the script is to enable the archiving of the dSYM symbols in a timestamped archive. No excuse to not keep the symbols anymore, and not be able to symbolicate the crash log you might later receive.

IMDB doesn't seem to have a direct API as of August 2016 yet but I saw many people writing scrapers and stuff above. Here is a more standard way to access movie data using box office buzz API. All responses in JSON format and 5000 queries per day on a free plan

List of things provided by the API

1. Movie Credits
2. Movie ID
3. Movie Images
4. Get movie by IMDB id
5. Get latest movies list
6. Get new releases
7. Get movie release dates
8. Get the list of translations available for a specific movie
9. Get videos, trailers, and teasers for a movie
10. Search for a movie by title
11. Also supports TV shows, games and videos

I had not agreed to the new updated licensed agreement from apple.

Briefly : Please log in to your developer's account -> profile's -> review -> read the agreement or get your lawyer read it for you -> agree (at your own will) -> and again click profile's to check the status of your profile.

In my scenario the valid code signing entity was not showing up. When i followed the above procedure it was visible and i was able to run the app on the device and/or create the iPA file without much difficulty.

Add a linefeed ("\n") to the output:

As many have pointed out, emacspeak has been the enduring solution cross platform for many of the older hackers out there. Since it supports Linux and Mac out of the box, it has become my prefered means of developing Windows egnostic projects.

To the issue of actually getting down syntax through an auditory one as opposed to a visual one, I have found that there exists a variety of techniques to get one close if not on the same playing field.

Auditory icons can stand in place for verbal descriptors for one example. You can, put tones for how far a line is indented. The longer the tone, the further the indent. Since tones can play in parallel with text to speech, the information comes through in the same timeframe and doesn't serialize the communication of something so basic.

Braille can quickly and precisely decode to the user the exact syntax of a line. This is something more useful for people who use braille in daily life; the biggest advantage is random access to the contents of the display. Refreshable units typically have router keys above each character cell which can place the cursor to that cell. No fiddling with arrow keys O(n) op vs O(1) access.

Auditory dimensionality (pitch, rate, volume, inflection, richness, stress, etc) can convey a concept (keyword, class, variable, error, etc). For example, comments can be read in a monotone inflection...suiting, if I might say so :).

Emacs and other editors to lesser extents (Visual Studio) allow a coder to peruse a program symantically (next block, fold block, down defun, jump to def, walk up the parse tree, etc). You can very quickly get the "big" picture of the structure of an entire project doing this; with extensions like Cedet, you can get the goodness of VS/Eclipse/etc cross platform and in a textual editor.

Could probably go on and on, but that in a nutshell, is the basis of why a few of us are out there hacking away in industry, adacdemia, or in our basements :).

It turns out that this is important enough to get it's own module...

import base64
base64.b64encode(b'your name')  # b'eW91ciBuYW1l'
base64.b64encode('your name'.encode('ascii'))  # b'eW91ciBuYW1l'

In SQL Server 2017 & later, use Trim

Select Trim(char(10) + char(13) from @str)

1. it trims on starting and ending, not in the middle
2. the order of \r and \n does not matter

I use it to trim special characters for a file name

Select Trim(char(10) + char(13) + ' *<>' from @fileName)

A Pending Intent is a token you give to some app to perform an action on your apps' behalf irrespective of whether your application process is alive or not.

I think the documentation is sufficiently detailed: Pending Intent docs.

Just think of use-cases for Pending Intents like (Broadcasting Intents, scheduling alarms) and the documentation will become clearer and meaningful.

For me, I was trying to add [formGroupName]="i" and/or formControlName and forgetting to specify the parent formArrayName. Pay attention to your form group tree.

When you start a thread you are executing a method of some chosen class. All attributes of that class are visible.

  Worker myWorker = new Worker( /* arguments */ );

  Thread myThread = new Thread(new ThreadStart(myWorker.doWork));

  myThread.Start();

Your thread is now in the doWork() method and can see any atrributes of myWorker, which may themselves be other objects. Now you just need to be careful to deal with the cases of having several threads all hitting those attributes at the same time.

Try to check outline on button's focus:

button:focus {
    outline: blue auto 5px; 
}

If you have it, just set it to none.

For completeness, in addition to the other answers, if the thread is interrupted before it blocks on Object.wait(..) or Thread.sleep(..) etc., this is equivalent to it being interrupted immediately upon blocking on that method, as the following example shows.

public class InterruptTest {
    public static void main(String[] args) {

        Thread.currentThread().interrupt();

        printInterrupted(1);

        Object o = new Object();
        try {
            synchronized (o) {
                printInterrupted(2);
                System.out.printf("A Time %d\n", System.currentTimeMillis());
                o.wait(100);
                System.out.printf("B Time %d\n", System.currentTimeMillis());
            }
        } catch (InterruptedException ie) {
            System.out.printf("WAS interrupted\n");
        }
        System.out.printf("C Time %d\n", System.currentTimeMillis());

        printInterrupted(3);

        Thread.currentThread().interrupt();

        printInterrupted(4);

        try {
            System.out.printf("D Time %d\n", System.currentTimeMillis());
            Thread.sleep(100);
            System.out.printf("E Time %d\n", System.currentTimeMillis());
        } catch (InterruptedException ie) {
            System.out.printf("WAS interrupted\n");
        }
        System.out.printf("F Time %d\n", System.currentTimeMillis());

        printInterrupted(5);

        try {
            System.out.printf("G Time %d\n", System.currentTimeMillis());
            Thread.sleep(100);
            System.out.printf("H Time %d\n", System.currentTimeMillis());
        } catch (InterruptedException ie) {
            System.out.printf("WAS interrupted\n");
        }
        System.out.printf("I Time %d\n", System.currentTimeMillis());

    }
    static void printInterrupted(int n) {
        System.out.printf("(%d) Am I interrupted? %s\n", n,
                Thread.currentThread().isInterrupted() ? "Yes" : "No");
    }
}

Output:

$ javac InterruptTest.java 

$ java -classpath "." InterruptTest
(1) Am I interrupted? Yes
(2) Am I interrupted? Yes
A Time 1399207408543
WAS interrupted
C Time 1399207408543
(3) Am I interrupted? No
(4) Am I interrupted? Yes
D Time 1399207408544
WAS interrupted
F Time 1399207408544
(5) Am I interrupted? No
G Time 1399207408545
H Time 1399207408668
I Time 1399207408669

Implication: if you loop like the following, and the interrupt occurs at the exact moment when control has left Thread.sleep(..) and is going around the loop, the exception is still going to occur. So it is perfectly safe to rely on the InterruptedException being reliably thrown after the thread has been interrupted:

while (true) {
    try {
        Thread.sleep(10);
    } catch (InterruptedException ie) {
        break;
    }
}

If you want to use column names to select the columns, simply use .(), which is an alias for list():

library(data.table)
dt <- data.table(a = 1:2, b = 2:3, c = 3:4)
dt[ , .(b, c)] # select the columns b and c
# Result:
#    b c
# 1: 2 3
# 2: 3 4

If you only want to match "" as an empty string

WHERE DATALENGTH(COLUMN) > 0 

If you want to count any string consisting entirely of spaces as empty

WHERE COLUMN <> '' 

Both of these will not return NULL values when used in a WHERE clause. As NULL will evaluate as UNKNOWN for these rather than TRUE.

CREATE TABLE T 
  ( 
     C VARCHAR(10) 
  ); 

INSERT INTO T 
VALUES      ('A'), 
            (''),
            ('    '), 
            (NULL); 

SELECT * 
FROM   T 
WHERE  C <> ''

Returns just the single row A. I.e. The rows with NULL or an empty string or a string consisting entirely of spaces are all excluded by this query.

SQL Fiddle

<label>Mobile Number(*)</label>
<input id="txtMobile" ng-maxlength="10" maxlength="10" Validate-phone  required  name='strMobileNo' ng-model="formModel.strMobileNo" type="text"  placeholder="Enter Mobile Number">
<span style="color:red" ng-show="regForm.strMobileNo.$dirty && regForm.strMobileNo.$invalid"><span ng-show="regForm.strMobileNo.$error.required">Phone is required.</span>

      elm.on("keyup",function(){
            var isMatchRegex = PHONE_REGEXP.test(elm.val());
            if( isMatchRegex&& elm.hasClass('warning') || elm.val() == ''){
              elm.removeClass('warning');
            }else if(isMatchRegex == false && !elm.hasClass('warning')){
              elm.addClass('warning');

as others said Calendar.MONTH returns int and is zero indexed.

to get the current month as a String use SimpleDateFormat.format() method

Calendar cal = Calendar.getInstance();
System.out.println(new SimpleDateFormat("MMM").format(cal.getTime()));

returns NOV

Try adding the css style property

position:relative;

to the div tag , it works ,

A frequent source of these bugs is when you have a method that accepts a reference or pointer to an object but leaves ownership unclear. Style and commenting conventions can make this less likely.

Let the case where the function takes ownership of the object be the special case. In all situations where this happens, be sure to write a comment next to the function in the header file indicating this. You should strive to make sure that in most cases the module or class which allocates an object is also responsible for deallocating it.

Using const can help a lot in some cases. If a function will not modify an object, and does not store a reference to it that persists after it returns, accept a const reference. From reading the caller's code it will be obvious that your function has not accepted ownership of the object. You could have had the same function accept a non-const pointer, and the caller may or may not have assumed that the callee accepted ownership, but with a const reference there's no question.

Do not use non-const references in argument lists. It is very unclear when reading the caller code that the callee may have kept a reference to the parameter.

I disagree with the comments recommending reference counted pointers. This usually works fine, but when you have a bug and it doesn't work, especially if your destructor does something non-trivial, such as in a multithreaded program. Definitely try to adjust your design to not need reference counting if it's not too hard.

Thread wait on the monitoring object (object used by synchronization block), There can be n number of monitoring object in whole journey of a single thread. If Thread wait outside the synchronization block then there is no monitoring object and also other thread notify to access for the monitoring object, so how would the thread outside the synchronization block would know that it has been notified. This is also one of the reason that wait(), notify() and notifyAll() are in object class rather than thread class.

Basically the monitoring object is common resource here for all the threads, and monitoring objects can only be available in synchronization block.

class A {
   int a = 0;
  //something......
  public void add() {
   synchronization(this) {
      //this is your monitoring object and thread has to wait to gain lock on **this**
       }
  }

Ok so, I'm using Linux but I think this holds true for Windows too. You can do this either directly from the command prompt

> mysql -u <user name> -p<password> <database name> < sqlfilename.sql

Or from within the mysql prompt, you can use:

mysql>source sqlfilename.sql

But both these approaches have their own benefits in the results they display. In the first approach, the script exits as soon as it encounters an error. And the better part, is that it tells you the exact line number in the source file where the error occurred. However, it ONLY displays errors. If it didn't encounter any errors, the scripts displays NOTHING. Which can be a little unnerving. Because you're most often running a script with a whole pile of commands.

Now second approach (from within the mysql prompt) has the benefit that it displays a message for every different MySQL command in the script. If it encounters errors, it displays the mysql error message but continues on through the scripts. This can be good, because you can then go back and fix all the errors before you run the script again. The downside is that it does NOT display the line numbers in the script where the errors were encountered. This can be a bit of a pain. But the error messages are as descriptive so you could probably figure out where the problem is.

I, for one, prefer the directly-from-OS-command line approach.

With the Angular CLI it's easy. An example for Heroku:

1. Create a Heroku account and install the CLI

2. Move the angular-cli dep to the dependencies in package.json (so that it gets installed when you push to Heroku.

3. Add a postinstall script that will run ng build when the code gets pushed to Heroku. Also add a start command for a Node server that will be created in the following step. This will place the static files for the app in a dist directory on the server and start the app afterward.

"scripts": {
  // ...
  "start": "node server.js",
  "postinstall": "ng build --aot -prod"
}

4. Create an Express server to serve the app.

// server.js
const express = require('express');
const app = express();
// Run the app by serving the static files
// in the dist directory
app.use(express.static(__dirname + '/dist'));
// Start the app by listening on the default
// Heroku port
app.listen(process.env.PORT || 8080);

5. Create a Heroku remote and push to depoy the app.

heroku create
git add .
git commit -m "first deploy"
git push heroku master

Here's a quick writeup I did that has more detail, including how to force requests to use HTTPS and how to handle PathLocationStrategy :)

These are Open Source projects (or developers) which can use donations to fund to help support their business.

In npm the command npm fund will list the urls where you can fund

In composer the command composer fund will do the same.

While there are options mentioned above using which one can use to get rid of the funding message, but try to support the cause if you can.

also try this way

$('input:radio[name="name"][id="abcd'+no+'"]').attr("checked", "checked");

if there is <form /> tag then ("checked", true) otherwise ("checked", "checked")

Depends on how your data is distributed. For a simple counter, the simplest function

f(i) = i

will be good (I suspect optimal, but I can't prove it).

More accurately anything that is not 0 is true.

So 1 is true, but so is 2, 3 ... etc.

eg:

// .vscode/settings.json in workspace

{
  "files.associations": {
    "*Container.js": "javascriptreact",
    "**/components/*/*.js": "javascriptreact",
    "**/config/routes.js": "javascriptreact"
  }
}

You may have also put your console.log after an expectation that fails and is uncaught, so your log line never gets executed.

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.

Here the code to use your app.js

input specifies file name

res.download(__dirname+'/'+input);

It is better to look up shadow:

    box-shadow: 0 -8px 73px 0 rgba(0,0,0,0.2);

Is there a way to get a list of all the keys in a Go language map?

ks := reflect.ValueOf(m).MapKeys()

how do I iterate over all the keys?

Use the accepted answer:

for k, _ := range m { ... }

You could use the substr function please check following example,

$string1 = "tarunmodi";
$first4 = substr($string1, 4);
echo $first4;

Output: nmodi

for i in "${array[@]}"

        echo "Found"
    fi
done

For strings:

for i in "${array[@]}"
do
    if [ "$i" == "$yourValue" ] ; then
        echo "Found"
    fi
done

RFC6690 - Constrained RESTful Environments (CoRE) Link Format Does not explicitly state what Date format should be however in section 2. Link Format it points to RFC 3986. This implies that recommendation for date type in RFC 3986 should be used.

Basically RFC 3339 Date and Time on the Internet is the document to look at that says:

date and time format for use in Internet protocols that is a profile of the ISO 8601 standard for representation of dates and times using the Gregorian calendar.

what this boils down to : YYYY-MM-ddTHH:mm:ss.ss±hh:mm

(e.g 1937-01-01T12:00:27.87+00:20)

Is the safest bet.

I found this on the MySQL support page for the Visual Studio connectors.

It appears that they do not support the MySQL to Visual Studio EXPRESS editions.

So to answer your question, yes you may need the ultimate version or professional edition - just not Express to be able to use MySQL with VS.

There are some changes required to JavaScript code to handle rendering based on user liking or not liking the page mandated by Facebook moving to Auth2.0 authorization.

Change is fairly simple:-

sessions has to be replaced by authResponse and uid by userID

Moreover given the requirement of the code and some issues faced by people(including me) in general with FB.login, use of FB.getLoginStatus is a better alternative. It saves query to FB in case user is logged in and has authenticated your app.

Refer to Response and Sessions Object section for info on how this might save query to FB server. http://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus/

For input and button:

$('button').prop('disabled', true);

For anchor:

$('a').attr('disabled', true);

For me I tried almost all the suggestions given above but the problem still reoccurred after the first success in uploading to App store. Until I found this website. In summary, do the following

1. Open terminal

2. Run this command:

     rm -rf ~/.itmstransporter/
     “/Applications/Xcode.app/Contents/Applications/Application 
     Loader.app/Contents/itms/bin/iTMSTransporter”
   

Note: this command(which is different from others above) will delete your ITMSTansporter folder and create a new one and ensure that xcode is quitted before running this command. 3. Start Xcode and all should be well.

In your example, because you use CurrentDB to execute your INSERT you've made it harder for yourself. Instead, this will work:

  Dim query As String
  Dim newRow As Long  ' note change of data type
  Dim db As DAO.Database

  query = "INSERT INTO InvoiceNumbers (date) VALUES (" & NOW() & ");"
  Set db = CurrentDB
  db.Execute(query)
  newRow = db.OpenRecordset("SELECT @@IDENTITY")(0)
  Set db = Nothing

I used to do INSERTs by opening an AddOnly recordset and picking up the ID from there, but this here is a lot more efficient. And note that it doesn't require ADO.

I think is better to use a Label(or TextBlock) into a Label, you can't attach a mouse event directly in the border control, finally it is attached in the TextBlock, this is my recomendation:

<Label 
    Height="32"
    VerticalContentAlignment="Center"
    HorizontalContentAlignment="Stretch"
    MouseLeftButtonUp="MenuItem_MouseLeftButtonUp">
    <TextBlock Padding="32 0 10 0">
        Label with click event
    </TextBlock>
</Label>

Make a datatable with one column instead of List and add strings to the table. You can pass this datatable as structured type and perform another join with title field of your table.

You need convert to number type:

(+Low).toFixed(2)

I have facing this issue many time. Please add following code for resolve this issue :

@Override
    public void onDestroyView() {
        super.onDestroyView();
        if (view != null) {
            ViewGroup parentViewGroup = (ViewGroup) view.getParent();
            if (parentViewGroup != null) {
                parentViewGroup.removeAllViews();
            }
        }
    }

Thanks

Not an exact answer to your question, but a bit of information: if your device does use NTP for time (eg. if it is a tablet with no 3G or GPS capabilities), the server can be configured in /system/etc/gps.conf - obviously this file can only be edited with root access, but is viewable on non-rooted devices.

Try to use INSERT instead of SELECT INTO:

   DECLARE @UserData TABLE(
                        name varchar(30) NOT NULL,
                        oldlocation varchar(30) NOT NULL
                       )

    INSERT @UserData   
    SELECT name, oldlocation

To add 10px separation between each section just write this

flowLayout.sectionInset = UIEdgeInsetsMake(0.0, 0.0,10,0);

Instead of strtotime you should use DateTime with PHP. You can also regard the timezone this way:

$dt = DateTime::createFromFormat('Y-m-d H:i:s', $mysqltime, new DateTimeZone('Europe/Berlin'));
$unix_timestamp = $dt->getTimestamp();

$mysqltime is of type MySQL Datetime, e. g. 2018-02-26 07:53:00.

I tried the solutions above yet the value that goes to the model were the formatted value then returning and giving me currencyPipe errors. So i had to

  [ngModel]="transfer.amount | currency:'USD':true"
                                   (blur)="addToAmount($event.target.value)"
                                   (keypress)="validateOnlyNumbers($event)"

And on the function of addToAmount -> change on blur cause the ngModelChange was giving me cursor issues.

removeCurrencyPipeFormat(formatedNumber){
    return formatedNumber.replace(/[$,]/g,"")
  }

And removing the other non numeric values.

validateOnlyNumbers(evt) {
  var theEvent = evt || window.event;
  var key = theEvent.keyCode || theEvent.which;
  key = String.fromCharCode( key );
  var regex = /[0-9]|\./;
  if( !regex.test(key) ) {
    theEvent.returnValue = false;
    if(theEvent.preventDefault) theEvent.preventDefault();
  }

You can use Git GUI on Windows, see instructions:

1. Open the Git Gui (After installing the Git on your computer).

2. Clone your repository to your local hard drive:

3. After cloning, GUI opens, choose: "Rescan" for changes that you made:

4. You will notice the scanned files:

5. Click on "Stage Changed":

6. Approve and click "Commit":

7. Click on "Push":

8. Click on "Push":

9. Wait for the files to upload to git:

string.Join("", (from i in arr select i.ToString()).ToArray())

In the .NET 4.0 the string.Join can use an IEnumerable<string> directly:

string.Join("", from i in arr select i.ToString())

There is notable difference between const and readonly fields in C#.Net

const is by default static and needs to be initialized with constant value, which can not be modified later on. Change of value is not allowed in constructors, too. It can not be used with all datatypes. For ex- DateTime. It can not be used with DateTime datatype.

public const DateTime dt = DateTime.Today;  //throws compilation error
public const string Name = string.Empty;    //throws compilation error
public readonly string Name = string.Empty; //No error, legal

readonly can be declared as static, but not necessary. No need to initialize at the time of declaration. Its value can be assigned or changed using constructor. So, it gives advantage when used as instance class member. Two different instantiation may have different value of readonly field. For ex -

class A
{
    public readonly int Id;

    public A(int i)
    {
        Id = i;
    }
}

Then readonly field can be initialised with instant specific values, as follows:

A objOne = new A(5);
A objTwo = new A(10);

Here, instance objOne will have value of readonly field as 5 and objTwo has 10. Which is not possible using const.

You must add your keyListener to every component that you need. Only the component with the focus will send these events. For instance, if you have only one TextBox in your JFrame, that TextBox has the focus. So you must add a KeyListener to this component as well.

The process is the same:

myComponent.addKeyListener(new KeyListener ...);

Note: Some components aren't focusable like JLabel.

For setting them to focusable you need to:

myComponent.setFocusable(true);

This might be old. But, it just occurred in angular, the content type for request and response were different in my code. So, check headers for ,

 let headers = new Headers({
        'Content-Type': 'application/json',
        **Accept**: 'application/json'
    });

in React axios

axios({
  method:'get',
  url:'http://  ',
 headers: {
         'Content-Type': 'application/json',
        Accept: 'application/json'
    },
  responseType:'json'
})

jQuery Ajax:

 $.ajax({
      url: this.props.url,
      dataType: 'json',
**headers: { 
          'Content-Type': 'application/json',
        Accept: 'application/json'
    },**
      cache: false,
      success: function (data) {
        this.setState({ data: data });
      }.bind(this),
      error: function (xhr, status, err) {
        console.error(this.props.url, status, err.toString());
      }.bind(this)
    });
  },

For 2.3 seconds you should do:

System.Threading.Thread.Sleep(2300);

Both pandas and matplotlib.dates use matplotlib.units for locating the ticks.

But while matplotlib.dates has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).

So for the moment it seems more reasonable to use matplotlib.dates (as mentioned by @BrenBarn in his comment).

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt 
import matplotlib.dates as dates

idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)

fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
                                                interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))
plt.tight_layout()
plt.show()

(my locale is German, so that Tuesday [Tue] becomes Dienstag [Di])

Another option would be to just use the excellent corrr package https://github.com/drsimonj/corrr and do

require(corrr)
require(dplyr)

myData %>% 
   select(x,y,z) %>%  # or do negative or range selections here
   correlate() %>%
   rearrange() %>%  # rearrange by correlations
   shave() # Shave off the upper triangle for a cleaner result

Steps 3 and 4 are entirely optional and are just included to demonstrate the usefulness of the package.

I want to just refresh the div, without refreshing the page ... Is this possible?

Yes, though it isn't going to be obvious that it does anything unless you change the contents of the div.

If you just want the graphical fade-in effect, simply remove the .html(data) call:

$("#panel").hide().fadeIn('fast');

Here is a demo you can mess around with: http://jsfiddle.net/ZPYUS/

It changes the contents of the div without making an ajax call to the server, and without refreshing the page. The content is hard coded, though. You can't do anything about that fact without contacting the server somehow: ajax, some sort of sub-page request, or some sort of page refresh.

html:

<div id="panel">test data</div>
<input id="changePanel" value="Change Panel" type="button">?

javascript:

$("#changePanel").click(function() {
    var data = "foobar";
    $("#panel").hide().html(data).fadeIn('fast');
});?

css:

div {
    padding: 1em;
    background-color: #00c000;
}

input {
    padding: .25em 1em;
}?

In Matlab, you can iterate over the elements in the list directly. This can be useful if you don't need to know which element you're currently working on.

Thus you can write

for elm = list
%# do something with the element
end

Note that Matlab iterates through the columns of list, so if list is a nx1 vector, you may want to transpose it.

Try to change CREATE FUNCTION F_TEST(PID INT) RETURNS VARCHAR this portion to CREATE FUNCTION F_TEST(PID INT) RETURNS TEXT

and change the following line too.

DECLARE NAME_FOUND TEXT DEFAULT "";

It should work.

The following solution combines other answers and handles some special cases:

• The parameter does not exist in the original url
• The parameter is the only parameter
• The parameter is first or last
• The new parameter value is the same as the old
• The url ends with a ? character
• \b ensures another parameter ending with paramName won't be matched

Solution:

function replaceUrlParam(url, paramName, paramValue)
{
    if (paramValue == null) {
        paramValue = '';
    }
    var pattern = new RegExp('\\b('+paramName+'=).*?(&|#|$)');
    if (url.search(pattern)>=0) {
        return url.replace(pattern,'$1' + paramValue + '$2');
    }
    url = url.replace(/[?#]$/,'');
    return url + (url.indexOf('?')>0 ? '&' : '?') + paramName + '=' + paramValue;
}

Known limitations:

• Does not clear a parameter by setting paramValue to null, instead it sets it to empty string. See https://stackoverflow.com/a/25214672 if you want to remove the parameter.

Here is how I set the max thread count flag mentioned above programatically and a code sniped to verify that the parameter is honored

System.setProperty("java.util.concurrent.ForkJoinPool.common.parallelism", "2");
Set<String> threadNames = Stream.iterate(0, n -> n + 1)
  .parallel()
  .limit(100000)
  .map(i -> Thread.currentThread().getName())
  .collect(Collectors.toSet());
System.out.println(threadNames);

// Output -> [ForkJoinPool.commonPool-worker-1, Test worker, ForkJoinPool.commonPool-worker-3]

The default behaviour of Newtonsoft.Json is going to find the public constructors. If your default constructor is only used in containing class or the same assembly, you can reduce the access level to protected or internal so that Newtonsoft.Json will pick your desired public constructor.

Admittedly, this solution is rather very limited to specific cases.

internal Result() { }

public Result(int? code, string format, Dictionary<string, string> details = null)
{
    Code = code ?? ERROR_CODE;
    Format = format;

    if (details == null)
        Details = new Dictionary<string, string>();
    else
        Details = details;
}

SWIFT 4 Update

 @IBOutlet weak var tripDetails: UILabel!

 override func viewDidLoad() {
    super.viewDidLoad()

    let tap = UITapGestureRecognizer(target: self, action: #selector(GameViewController.tapFunction))
    tripDetails.isUserInteractionEnabled = true
    tripDetails.addGestureRecognizer(tap)
}

@objc func tapFunction(sender:UITapGestureRecognizer) {

    print("tap working")
}

The shared pointer manages both the object itself, and a small object containing the reference count and other housekeeping data. make_shared can allocate a single block of memory to hold both of these; constructing a shared pointer from a pointer to an already-allocated object will need to allocate a second block to store the reference count.

As well as this efficiency, using make_shared means that you don't need to deal with new and raw pointers at all, giving better exception safety - there is no possibility of throwing an exception after allocating the object but before assigning it to the smart pointer.

Knockout.js validation is handy but it is not robust. You always have to create server side validation replica. In your case (as you use knockout.js) you are sending JSON data to server and back asynchronously, so you can make user think that he sees client side validation, but in fact it would be asynchronous server side validation.

Take a look at example here upida.cloudapp.net:8080/org.upida.example.knockout/order/create?clientId=1 This is a "Create Order" link. Try to click "save", and play with products. This example is done using upida library (there are spring mvc version and asp.net mvc of this library) from codeplex.

s = s.Substring(0, Math.Max(0, s.Length - 2))

to include the case where the length is less than 2

To remove all the constraints from the DB:

SELECT 'ALTER TABLE ' + Table_Name  +' DROP CONSTRAINT ' + Constraint_Name
FROM Information_Schema.CONSTRAINT_TABLE_USAGE

Character sets will help out a ton here. You want to create a matching set for the characters that you want to validate:

• You can match alphanumeric with a \w, which is the same as [A-Za-z0-9_] in JavaScript (other languages can differ).
• That leaves - and spaces, which can be combined into a matching set such as [\w\- ]. However, you may want to consider using \s instead of just the space character (\s also matches tabs, and other forms of whitespace)
  • Note that I'm escaping - as \- so that the regex engine doesn't confuse it with a character range like A-Z
• Last up, you probably want to ensure that the entire string matches by anchoring the start and end via ^ and $

The full regex you're probably looking for is:

/^[\w\-\s]+$/

(Note that the + indicates that there must be at least one character for it to match; use a * instead, if a zero-length string is also ok)

Finally, http://www.regular-expressions.info/ is an awesome reference

Bonus Points: This regex does not match non-ASCII alphas. Unfortunately, the regex engine in most browsers does not support named character sets, but there are some libraries to help with that.

For languages/platforms that do support named character sets, you can use /^[\p{Letter}\d\_\-\s]+$/

I have to make an application which shows the Contact no of the SIM card that is being used in the cell. For that I need to use Telephony Manager class. Can i get details on its usage?

Yes, You have to use Telephony Manager;If at all you not found the contact no. of user; You can get Sim Serial Number of Sim Card and Imei No. of Android Device by using the same Telephony Manager Class...

Add permission:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Import:

import android.telephony.TelephonyManager;

Use the below code:

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

         // get IMEI
         imei = tm.getDeviceId();

         // get SimSerialNumber
         simSerialNumber = tm.getSimSerialNumber();

first use @Html.AntiForgeryToken() in html

 $.ajax({
        url: "@Url.Action("SomeMethod", "SomeController")",
        type: 'POST',
        data: JSON.stringify(jsonObject),
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        async: false,
        beforeSend: function (request) {
            request.setRequestHeader("RequestVerificationToken", $("[name='__RequestVerificationToken']").val());
        },
        success: function (msg) {
            alert(msg);
        }

df.T.iloc[-1]

df.T.tail(1)

pd.Series(df.values[:, -1], name=df.columns[-1])

None of the above things worked for me as I had multiple recipients both in 'to' and 'cc'. So I tried like below:

recipients = ['[email protected]', '[email protected]']
cc_recipients = ['[email protected]', '[email protected]']
MESSAGE['To'] = ", ".join(recipients)
MESSAGE['Cc'] = ", ".join(cc_recipients)

and extend the 'recipients' with 'cc_recipients' and send mail in trivial way

recipients.extend(cc_recipients)
server.sendmail(FROM,recipients,MESSAGE.as_string())

Varying is an alias for varchar, so no difference, see documentation :)

The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.

To revert a merge commit, you need to use: git revert -m <parent number>. So for example, to revert the recent most merge commit using the parent with number 1 you would use:

git revert -m 1 HEAD

To revert a merge commit before the last commit, you would do:

git revert -m 1 HEAD^

Use git show <merge commit SHA1> to see the parents, the numbering is the order they appear e.g. Merge: e4c54b3 4725ad2

git merge documentation: http://schacon.github.com/git/git-merge.html

void segfault_sigaction(int signal, siginfo_t *si, void *arg)
{
    printf("Caught segfault at address %p\n", si->si_addr);
    exit(0);
}

int main(void)
{
    int *foo = NULL;
    struct sigaction sa;

    memset(&sa, 0, sizeof(struct sigaction));
    sigemptyset(&sa.sa_mask);
    sa.sa_sigaction = segfault_sigaction;
    sa.sa_flags   = SA_SIGINFO;

    sigaction(SIGSEGV, &sa, NULL);

    /* Cause a seg fault */
    *foo = 1;

    return 0;
}

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

On windows in a corporate environment where certificates are distributed from a single source, I found this answer solved the issue: https://stackoverflow.com/a/48212753/761755

Problem - I was not able to connect to DB through sql developer.

Solution - First thing to note is that SQL Developer is only UI to access to your database. I need to connect remote database not the localhost so I need not to install the oracle 8i/9i. Only I need is oracle client to install. After installation it got the path in environment variable like C:\oracle\product\10.2.0\client_1\bin. Still I was not able to connect the db.

Things to be checked.

1. Listner/port should be up for the server IP where you want to connect.
2. you will be able to ping the server. go to cmd prompt. type ping server Ip then enter.
3. telnet the server IP and port. should be succesful.

If all points are ok for you then check from where you are running sql developer .exe file. I pasted sql developer folder to C:\oracle folder and run the .exe file from here and I am able to connect the database. and my problem of 'IO Error: The Network Adapter could not establish the connection' got resolved. Hurrey... :) :)

For Tomcat v8.5.4 and above, the file <tomcat>/webapps/manager/META-INF/context.xml has been adjusted:

<Context antiResourceLocking="false" privileged="true" >
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
</Context>

Change this file to comment the Valve:

<Context antiResourceLocking="false" privileged="true" >
    <!--
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
    -->
</Context>

After that, refresh your browser (not need to restart Tomcat), you can see the manager page.

Anaconda is a very large installation ~ 2 GB and is most useful for those users who are not familiar with installing modules or packages with other package managers.

Anaconda seems to be promoting itself as the official package manager of Jupyter. It's not. Anaconda bundles Jupyter, R, python, and many packages with its installation.

Anaconda is not necessary for installing Jupyter Lab or the R kernel. There is plenty of information available elsewhere for installing Jupyter Lab or Notebooks. There is also plenty of information elsewhere for installing R studio. The following shows how to install the R kernel directly from R Studio:

To install the R kernel, without Anaconda, start R Studio. In the R terminal window enter these three commands:

install.packages("devtools")
devtools::install_github("IRkernel/IRkernel")
IRkernel::installspec()

Done. Next time Jupyter is opened, the R kernel will be available.

For Mac OS, you'll have to remove permissions, but leave the directory

In many applications, like MsOffice (until version 2000 or 2002), the maximum number of characters per cell was 255. Moving data from programs able of handling more than 255 characters per field to/from those applications was a nightmare. Currently, the limit is less and less hindering.

The error says it all...

Msg 1033, Level 15, State 1, Procedure TestView, Line 5 The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.

Don't use TOP 100 PERCENT, use TOP n, where N is a number

The TOP 100 PERCENT (for reasons I don't know) is ignored by SQL Server VIEW (post 2012 versions), but I think MS kept it for syntax reasons. TOP n is better and will work inside a view and sort it the way you want when a view is used initially, but be careful.

I would use itertools.chain - this will also cater for > 1 element in each sublist:

from itertools import chain
list(chain.from_iterable([[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]))

On the offchance you accidentally lock yourself out of Jenkins due to a permission mistake, and you dont have server-side access to switch to the jenkins user or root... You can make a job in Jenkins and add this to the Shell Script:

sed -i 's/<useSecurity>true/<useSecurity>false/' ~/config.xml

Then click Build Now and restart Jenkins (or the server if you need to!)

You can't do it at all, let alone quickly. Arrays in Java are fixed size. Two things you could do are:

1. Shift every element up one, then set the last element to null.
2. Create a new array, then copy it.

You can use System.arraycopy for either of these. Both of these are O(n), since they copy all but 1 element.

If you will be removing the first element often, consider using LinkedList instead. You can use LinkedList.remove, which is from the Queue interface, for convenience. With LinkedList, removing the first element is O(1). In fact, removing any element is O(1) once you have a ListIterator to that position. However, accessing an arbitrary element by index is O(n).

Try checking for the :visible property instead.

if($('#car2').not(':visible'))
{
    alert('car 2 is hidden');       
}

Description

You can use the Console.SetCursorPosition function to go to a specific line number. Than you can use this function to clear the line

public static void ClearCurrentConsoleLine()
{
    int currentLineCursor = Console.CursorTop;
    Console.SetCursorPosition(0, Console.CursorTop);
    Console.Write(new string(' ', Console.WindowWidth)); 
    Console.SetCursorPosition(0, currentLineCursor);
}

Sample

Console.WriteLine("Test");
Console.SetCursorPosition(0, Console.CursorTop - 1);
ClearCurrentConsoleLine();

More Information

• Console.SetCursorPosition Method

function update(datetime = "2017-01-01 05:11:58") {
    var theevent = new Date(datetime);
    now = new Date();
    var sec_num = (theevent - now) / 1000;
    var days    = Math.floor(sec_num / (3600 * 24));
    var hours   = Math.floor((sec_num - (days * (3600 * 24)))/3600);
    var minutes = Math.floor((sec_num - (days * (3600 * 24)) - (hours * 3600)) / 60);
    var seconds = Math.floor(sec_num - (days * (3600 * 24)) - (hours * 3600) - (minutes * 60));

    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}

    return  days+':'+ hours+':'+minutes+':'+seconds;
}

In some contexts, you can leverage margin settings to effectively specify "100% width minus N pixels". See the accepted answer to this question.

You cant combine this to attributes.

But you can put both on one action method but you can encapsulate your logic into a other method and call this method from both actions.

The ActionName Attribute allows to have 2 ActionMethods with the same name.

[HttpGet]
public ActionResult MyMethod()
{
    return MyMethodHandler();
}

[HttpPost]
[ActionName("MyMethod")]
public ActionResult MyMethodPost()
{
    return MyMethodHandler();
}

private ActionResult MyMethodHandler()
{
    // handle the get or post request
    return View("MyMethod");
}

1. Go to the Build Path settings in the project properties.
2. Remove the JRE System Library
3. Add it back; Select "Add Library" and select the JRE System Library. The default worked for me.

I was in a process of switching from one version control service to another and needed to clone all repositories including all branches, tags and history.

To achieve above I did next:

• manually checkout all branches to local repository (script to checkout all shown below),
• git push origin '*:*'

.sh script used to checkout all branches to local repository:

for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master `; do
   git branch --track ${branch#remotes/origin/} $branch
done

Use dropna:

dat.dropna()

You can pass param how to drop if all labels are nan or any of the labels are nan

dat.dropna(how='any')    #to drop if any value in the row has a nan
dat.dropna(how='all')    #to drop if all values in the row are nan

Hope that answers your question!

Edit 1: In case you want to drop rows containing nan values only from particular column(s), as suggested by J. Doe in his answer below, you can use the following:

dat.dropna(subset=[col_list])  # col_list is a list of column names to consider for nan values.

rem set defaults:
set filename1="c:\file1.txt"
set filename2="c:\file2.txt"
set filename3="c:\file3.txt"
rem set parameters:
IF NOT "a%1"=="a" (set filename1="%1")
IF NOT "a%2"=="a" (set filename2="%2")
IF NOT "a%3"=="a" (set filename1="%3")
echo %filename1%, %filename2%, %filename3%

Be careful with quotation characters though, you may or may not need them in your variables.

This is a function we are using in our application and it is working fine.

delete cookie: No argument method

function clearListCookies()
{   
    var cookies = document.cookie.split(";");
    for (var i = 0; i < cookies.length; i++)
    {   
        var spcook =  cookies[i].split("=");
        deleteCookie(spcook[0]);
    }
    function deleteCookie(cookiename)
    {
        var d = new Date();
        d.setDate(d.getDate() - 1);
        var expires = ";expires="+d;
        var name=cookiename;
        //alert(name);
        var value="";
        document.cookie = name + "=" + value + expires + "; path=/acc/html";                    
    }
    window.location = ""; // TO REFRESH THE PAGE

Edit: This will delete the cookie by setting it to yesterday's date.

Using Java:

private WebDriver driver = new FirefoxDriver();
WebElement element = driver.findElement(By.id("<ElementID>"));//Enter ID for the element. You can use Name, xpath, cssSelector whatever you like
element.sendKeys(Keys.TAB);
element.sendKeys(Keys.ENTER);

Using C#:

private IWebDriver driver = new FirefoxDriver();
IWebElement element = driver.FindElement(By.Name("q"));
element.SendKeys(Keys.Tab);
element.SendKeys(Keys.Enter);

Yes, but if you have your structure in a union then you cannot. It is the same as a class.

struct Example
{
   unsigned int mTest;
   Example()
   {
   }
};

Unions will not allow constructors in the structs. You can make a constructor on the union though. This question relates to non-trivial constructors in unions.

You can do it pretty fast without creating extra arrays, so this will work even for very large arrays:

dict(izip(*([iter(a)]*2)))

If you have a generator a, even better:

dict(izip(*([a]*2)))

Here's the rundown:

iter(h)    #create an iterator from the array, no copies here
[]*2       #creates an array with two copies of the same iterator, the trick
izip(*())  #consumes the two iterators creating a tuple
dict()     #puts the tuples into key,value of the dictionary

Swift 5 & iOS 13+ Programmatic Example

1. You must mark your function with @objc, see below example!
2. No parenthesis following after the function name! Just use #selector(name).
3. private or public doesn't matter; you can use private.

Code Example

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
    let menuButtonImage = UIImage(systemName: "flame")
    let menuButton = UIBarButtonItem(image: menuButtonImage, style: .plain, target: self, action: #selector(didTapMenuButton))
    navigationItem.rightBarButtonItem = menuButton
}

@objc public func didTapMenuButton() {
    print("Hello World")
}

If you are using ASP.NET Core MVC, the answers above are ever so slightly altered...

In my action method (which returns async Task<JsonResult>) I add the line (anywhere before the return statement):

Response.Headers.Add("Content-Disposition", $"attachment; filename={myFileName}");

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

CSS doesn't really allow you to do this on a table level. Generally, I specify cellspacing="3" when I want to achieve this effect. Obviously not a css solution, so take it for what it's worth.

Try;

<li>Text To go with Toggle Button<span class = 'toggle'><input type = 'checkbox' class = 'toggle' name = 'somename' id = 'someid' /></span></li>

And make sure in the

<head><link rel = 'stylesheet' src = 'theme.css'> (from jqtouch - downloadable online)
      <link rel = 'text/javascript' src = 'jquery.js'> (also from jqtouch)
</head>

Remember when you are coding this, only somename and someid can change in the input tag, otherwise it doesn't work.

tl;dr

LocalDate.parse( "2015-01-02" )

java.time

Java 8 and later has a new java.time framework that makes these other answers outmoded. This framework is inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project. See the Tutorial.

The old bundled classes, java.util.Date/.Calendar, are notoriously troublesome and confusing. Avoid them.

LocalDate

Like Joda-Time, java.time has a class LocalDate to represent a date-only value without time-of-day and without time zone.

ISO 8601

If your input string is in the standard ISO 8601 format of yyyy-MM-dd, you can ask that class to directly parse the string with no need to specify a formatter.

The ISO 8601 formats are used by default in java.time, for both parsing and generating string representations of date-time values.

LocalDate localDate = LocalDate.parse( "2015-01-02" );

Formatter

If you have a different format, specify a formatter from the java.time.format package. You can either specify your own formatting pattern or let java.time automatically localize as appropriate to a Locale specifying a human language for translation and cultural norms for deciding issues such as period versus comma.

Formatting pattern

Read the DateTimeFormatter class doc for details on the codes used in the format pattern. They vary a bit from the old outmoded java.text.SimpleDateFormat class patterns.

Note how the second argument to the parse method is a method reference, syntax added to Java 8 and later.

String input = "January 2, 2015";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern ( "MMMM d, yyyy" , Locale.US );
LocalDate localDate = LocalDate.parse ( input , formatter );

Dump to console.

System.out.println ( "localDate: " + localDate );

localDate: 2015-01-02

Localize automatically

Or rather than specify a formatting pattern, let java.time localize for you. Call DateTimeFormatter.ofLocalizedDate, and be sure to specify the desired/expected Locale rather than rely on the JVM’s current default which can change at any moment during runtime(!).

String input = "January 2, 2015";
DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDate ( FormatStyle.LONG );
formatter = formatter.withLocale ( Locale.US );
LocalDate localDate = LocalDate.parse ( input , formatter );

Dump to console.

System.out.println ( "input: " + input + " | localDate: " + localDate );

input: January 2, 2015 | localDate: 2015-01-02

I implemented a hasOne relation in my parent class, defined both the foreign and local key, it returned an object but the columns of the child must be accessed as an array.
i.e. $parent->child['column']
Kind of confusing.

Rename it to .zip, then extract it.

.*[^a]$

the regex above will match strings which is not ending with a.

I have found out one of the solutions. For your code this could be as follows -

XmlDocument xml = new XmlDocument();
try
{
    // assuming the location of the file is in the current directory 
    // assuming the file name be loadData.xml
    string myString = "./loadData.xml";
    xml.Load(myString);
}
catch (Exception ex)
{
    System.IO.File.WriteAllText(@"C:\text.txt", myString + "\r\n\r\n" + ex.Message);
    throw ex;
}

I've used the queuing approach, and it works well as you can defer that processing until your server load is idle, letting you manage your load quite effectively if you can partition off "tasks which aren't urgent" easily.

Rolling your own isn't too tricky, here's a few other options to check out:

• GearMan - this answer was written in 2009, and since then GearMan looks a popular option, see comments below.
• ActiveMQ if you want a full blown open source message queue.
• ZeroMQ - this is a pretty cool socket library which makes it easy to write distributed code without having to worry too much about the socket programming itself. You could use it for message queuing on a single host - you would simply have your webapp push something to a queue that a continuously running console app would consume at the next suitable opportunity
• beanstalkd - only found this one while writing this answer, but looks interesting
• dropr is a PHP based message queue project, but hasn't been actively maintained since Sep 2010
• php-enqueue is a recently (2017) maintained wrapper around a variety of queue systems
• Finally, a blog post about using memcached for message queuing

Another, perhaps simpler, approach is to use ignore_user_abort - once you've sent the page to the user, you can do your final processing without fear of premature termination, though this does have the effect of appearing to prolong the page load from the user perspective.

shell_exec returns all of the output stream as a string. exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter.

Isn't encoding taking the text TO base64 and decoding taking base64 BACK to text? You seem be mixing them up here. When I decode using this online decoder I get:

BASE64: blahblah
UTF8: nVnV

not the other way around. I can't reproduce it completely in PS though. See sample below:

PS > [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String("blahblah"))
nV?nV?

PS > [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes("nVnV"))
blZuVg==

EDIT I believe you're using the wrong encoder for your text. The encoded base64 string is encoded from UTF8(or ASCII) string.

PS > [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String("YmxhaGJsYWg="))
blahblah

PS > [System.Text.Encoding]::Unicode.GetString([System.Convert]::FromBase64String("YmxhaGJsYWg="))
????

PS > [System.Text.Encoding]::ASCII.GetString([System.Convert]::FromBase64String("YmxhaGJsYWg="))
blahblah

You can use dd to extract arbitrary chunks of bytes.

For example,

dd skip=1234 count=5 bs=1

would copy bytes 1235 to 1239 from its input to its output, and discard the rest.

To just get the first five bytes from standard input, do:

dd count=5 bs=1

Note that, if you want to specify the input file name, dd has old-fashioned argument parsing, so you would do:

dd count=5 bs=1 if=filename

Note also that dd verbosely announces what it did, so to toss that away, do:

dd count=5 bs=1 2>&-

or

dd count=5 bs=1 2>/dev/null

bool('True') and bool('False') always return True because strings 'True' and 'False' are not empty.

To quote a great man (and Python documentation):

5.1. Truth Value Testing

Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. The following values are considered false:

• …
• zero of any numeric type, for example, 0, 0L, 0.0, 0j.
• any empty sequence, for example, '', (), [].
• …

All other values are considered true — so objects of many types are always true.

The built-in bool function uses the standard truth testing procedure. That's why you're always getting True.

To convert a string to boolean you need to do something like this:

def str_to_bool(s):
    if s == 'True':
         return True
    elif s == 'False':
         return False
    else:
         raise ValueError # evil ValueError that doesn't tell you what the wrong value was

I created a function to do this, where you can specify the desired output character length:

CREATE FUNCTION [dbo].[udfLeadingZero]
(
        @String VARCHAR(MAX)
,       @Len INT
)
RETURNS VARCHAR(MAX)
BEGIN
    SET @String = RIGHT(REPLICATE('0',@Len)+@String,@Len)
RETURN @String
END
GO

Select multiple lines by clicking first line then holding shift and clicking last line. Then press:

CTRL+SHIFT+L

or on MAC: CMD+SHIFT+L (as per comments)

Alternatively you can select lines and go to SELECTION MENU >> SPLIT INTO LINES.

Now you can edit multiple lines, move cursors etc. for all selected lines.

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

\df <schema>.*

in psql gives the necessary information.

To see the query that's used internally connect to a database with psql and supply an extra "-E" (or "--echo-hidden") option and then execute the above command.

What you're looking for is date --date='06/12/2012 07:21:22' +"%s". Keep in mind that this assumes you're using GNU coreutils, as both --date and the %s format string are GNU extensions. POSIX doesn't specify either of those, so there is no portable way of making such conversion even on POSIX compliant systems.

Consult the appropriate manual page for other versions of date.

Note: bash --date and -d option expects the date in US or ISO8601 format, i.e. mm/dd/yyyy or yyyy-mm-dd, not in UK, EU, or any other format.

I read a lot of answers but none seems to correctly explain where the word double comes from. I remember a very good explanation given by a University professor I had some years ago.

Recalling the style of VonC's answer, a single precision floating point representation uses a word of 32 bit.

• 1 bit for the sign, S
• 8 bits for the exponent, 'E'
• 24 bits for the fraction, also called mantissa, or coefficient (even though just 23 are represented). Let's call it 'M' (for mantissa, I prefer this name as "fraction" can be misunderstood).

Representation:

          S  EEEEEEEE   MMMMMMMMMMMMMMMMMMMMMMM
bits:    31 30      23 22                     0

(Just to point out, the sign bit is the last, not the first.)

A double precision floating point representation uses a word of 64 bit.

• 1 bit for the sign, S
• 11 bits for the exponent, 'E'
• 53 bits for the fraction / mantissa / coefficient (even though only 52 are represented), 'M'

Representation:

           S  EEEEEEEEEEE   MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
bits:     63 62         52 51                                                  0

As you may notice, I wrote that the mantissa has, in both types, one bit more of information compared to its representation. In fact, the mantissa is a number represented without all its non-significative 0. For example,

• 0.000124 becomes 0.124 × 10^-3
• 237.141 becomes 0.237141 × 10³

This means that the mantissa will always be in the form

0.a₁a₂...a_t × ß^p

where ß is the base of representation. But since the fraction is a binary number, a₁ will always be equal to 1, thus the fraction can be rewritten as 1.a₂a₃...a_t+1 × 2^p and the initial 1 can be implicitly assumed, making room for an extra bit (a_t+1).

Now, it's obviously true that the double of 32 is 64, but that's not where the word comes from.

The precision indicates the number of decimal digits that are correct, i.e. without any kind of representation error or approximation. In other words, it indicates how many decimal digits one can safely use.

With that said, it's easy to estimate the number of decimal digits which can be safely used:

• single precision: log₁₀(2²⁴), which is about 7~8 decimal digits
• double precision: log₁₀(2⁵³), which is about 15~16 decimal digits

It is not (with current browsers) possible to make an input field read-only through CSS alone.

Though, as you have already mentioned, you can apply the attribute readonly='readonly'.

If your main criteria is to not alter the markup in the source, there are ways to get this in, unobtrusively, with javascript.

With jQuery, this is easy:

 $('input').attr('readonly', true);

Or even with plain Javascript:

document.getElementById('someId').setAttribute('readonly', 'readonly');

int count = reader.FieldCount;
while(reader.Read()) {
    for(int i = 0 ; i < count ; i++) {
        Console.WriteLine(reader.GetValue(i));
    }
}

Note; if you have multiple grids, then:

do {
    int count = reader.FieldCount;
    while(reader.Read()) {
        for(int i = 0 ; i < count ; i++) {
            Console.WriteLine(reader.GetValue(i));
        }
    }
} while (reader.NextResult())

I am combining the solutions from answers of @FredFoo and @Renaud. My solution is able to apply @Renaud's preprocessing on the text corpus of @FredFoo and then display pairwise similarities where the similarity is greater than 0. I ran this code on Windows by installing python and pip first. pip is installed as part of python but you may have to explicitly do it by re-running the installation package, choosing modify and then choosing pip. I use the command line to execute my python code saved in a file "similarity.py". I had to execute the following commands:

>set PYTHONPATH=%PYTHONPATH%;C:\_location_of_python_lib_
>python -m pip install sklearn
>python -m pip install nltk
>py similarity.py

The code for similarity.py is as follows:

from sklearn.feature_extraction.text import TfidfVectorizer
import nltk, string
import numpy as np
nltk.download('punkt') # if necessary...

stemmer = nltk.stem.porter.PorterStemmer()
remove_punctuation_map = dict((ord(char), None) for char in string.punctuation)

def stem_tokens(tokens):
    return [stemmer.stem(item) for item in tokens]

def normalize(text):
    return stem_tokens(nltk.word_tokenize(text.lower().translate(remove_punctuation_map)))

corpus = ["I'd like an apple", 
           "An apple a day keeps the doctor away", 
           "Never compare an apple to an orange", 
           "I prefer scikit-learn to Orange", 
           "The scikit-learn docs are Orange and Blue"]  

vect = TfidfVectorizer(tokenizer=normalize, stop_words='english')
tfidf = vect.fit_transform(corpus)   
                                                                                                                                                                                                                    
pairwise_similarity = tfidf * tfidf.T

#view the pairwise similarities 
print(pairwise_similarity)

#check how a string is normalized
print(normalize("The scikit-learn docs are Orange and Blue"))

Just:

dt = datetimeObject.strftime(format) # format = your datetime format ex) '%Y %d %m'
dt = datetime.datetime.strptime(dt,format)

So do this:

start_time = challenge.datetime_start.strftime('%Y %d %m %H %M %S')
start_time = datetime.datetime.strptime(start_time,'%Y %d %m %H %M %S')

end_time = challenge.datetime_end.strftime('%Y %d %m %H %M %S')
end_time = datetime.datetime.strptime(end_time,'%Y %d %m %H %M %S')

and then use start_time and end_time

The short answer: Yes but is not recommended.
The long answer: It depends on what you call valid...

ECMA-404 "The JSON Data Interchange Syntax" doesn't say anything about duplicated names (keys).

However, RFC 8259 "The JavaScript Object Notation (JSON) Data Interchange Format" says:

The names within an object SHOULD be unique.

In this context SHOULD must be understood as specified in BCP 14:

SHOULD This word, or the adjective "RECOMMENDED", mean that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course.

RFC 8259 explains why unique names (keys) are good:

An object whose names are all unique is interoperable in the sense that all software implementations receiving that object will agree on the name-value mappings. When the names within an object are not unique, the behavior of software that receives such an object is unpredictable. Many implementations report the last name/value pair only. Other implementations report an error or fail to parse the object, and some implementations report all of the name/value pairs, including duplicates.

Also, as Serguei pointed out in the comments: ECMA-262 "ECMAScript® Language Specification", reads:

In the case where there are duplicate name Strings within an object, lexically preceding values for the same key shall be overwritten.

In other words, last-value-wins.

Trying to parse a string with duplicated names with the Java implementation by Douglas Crockford (the creator of JSON) results in an exception:

org.json.JSONException: Duplicate key "status"  at
org.json.JSONObject.putOnce(JSONObject.java:1076)

In Java 8, you can use streams:

int[] spam = new int[] { 1, 2, 3 };
Arrays.stream(spam)
      .boxed()
      .collect(Collectors.toList());

Use a library instead

We don't have to reinvent the wheel. Just use a library to save the time and headache.

js-base64

https://github.com/dankogai/js-base64 is good and I confirm it supports unicode very well.

Base64.encode('dankogai');  // ZGFua29nYWk=
Base64.encode('???');    // 5bCP6aO85by+
Base64.encodeURI('???'); // 5bCP6aO85by-

Base64.decode('ZGFua29nYWk=');  // dankogai
Base64.decode('5bCP6aO85by+');  // ???
// note .decodeURI() is unnecessary since it accepts both flavors
Base64.decode('5bCP6aO85by-');  // ???

You need to create a set of escaped (with \) parentheses (that match the parentheses) and a group of regular parentheses that create your capturing group:

var regExp = /\(([^)]+)\)/;_x000D_
var matches = regExp.exec("I expect five hundred dollars ($500).");_x000D_
_x000D_
//matches[1] contains the value between the parentheses_x000D_
console.log(matches[1]);

Breakdown:

• \( : match an opening parentheses
• ( : begin capturing group
• [^)]+: match one or more non ) characters
• ) : end capturing group
• \) : match closing parentheses

Here is a visual explanation on RegExplained

In React 16.8+, using functional components, you would do

import React from 'react';
import { Button, Linking } from 'react-native';

const ExternalLinkBtn = (props) => {
  return <Button
            title={props.title}
            onPress={() => {
                Linking.openURL(props.url)
                .catch(err => {
                    console.error("Failed opening page because: ", err)
                    alert('Failed to open page')
                })}}
          />
}

export default function exampleUse() {
  return (
    <View>
      <ExternalLinkBtn title="Example Link" url="https://example.com" />
    </View>
  )
}

1. Create a new Application Pool

2. Go to the Advanced Settings of this application pool

3. Set the Enable 32-Bit Application to True

4. Point your web application to use this new Pool

There is another approach. In my example you see some business logic in repository class that I use with dependency injection in ASP .NET MVC Core 3.1.

And here I want to get connectiongString for that business logic because probably another repository will have access to another database at all.

This pattern allows you in the same business logic repository have access to different databases.

C#

public interface IStatsRepository
{
            IEnumerable<FederalDistrict> FederalDistricts();
}

class StatsRepository : IStatsRepository
{
   private readonly DbContextOptionsBuilder<EFCoreTestContext>
                optionsBuilder = new DbContextOptionsBuilder<EFCoreTestContext>();
   private readonly IConfigurationRoot configurationRoot;

   public StatsRepository()
   {
       IConfigurationBuilder configurationBuilder = new ConfigurationBuilder().SetBasePath(Environment.CurrentDirectory)
           .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
       configurationRoot = configurationBuilder.Build();
   }

   public IEnumerable<FederalDistrict> FederalDistricts()
   {
        var conn = configurationRoot.GetConnectionString("EFCoreTestContext");
        optionsBuilder.UseSqlServer(conn);

        using (var ctx = new EFCoreTestContext(optionsBuilder.Options))
        { 
            return ctx.FederalDistricts.Include(x => x.FederalSubjects).ToList();
        }
    }
}

appsettings.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "EFCoreTestContext": "Data Source=DESKTOP-GNJKL2V\\MSSQLSERVER2014;Database=Test;Trusted_Connection=True;MultipleActiveResultSets=true"
  }
}

Have you tried:

SELECT Cast( 2.555 as decimal(53,8))

This would return 2.55500000. Is that what you want?

UPDATE:

Apparently you can also use SQL_VARIANT_PROPERTY to find the precision and scale of a value. Example:

SELECT SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Precision'),
SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Scale')

returns 8|7

You may be able to use this in your conversion process...

This worked for me..

div.className {
display: inline-block;
margin: auto;
}

If you are using approach with class-based views and different 'action' attrs i mean

Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.

You can easily handle errors from different forms using overloaded get_context_data method, e.x:

views.py:

class LoginView(FormView):
    form_class = AuthFormEdited
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(LoginView, self).dispatch(request, *args, **kwargs)

    ....

    def get_context_data(self, **kwargs):
        context = super(LoginView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = True
        return context

class SignInView(FormView):
    form_class = SignInForm
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(SignInView, self).dispatch(request, *args, **kwargs)

    .....

    def get_context_data(self, **kwargs):
        context = super(SignInView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = False
        return context

template:

<div class="login-form">
<form action="/login/" method="post" role="form">
    {% csrf_token %}
    {% if login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
    .....
    </form>
</div>

<div class="signin-form">
<form action="/registration/" method="post" role="form">
    {% csrf_token %}
    {% if not login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
   ....
  </form>
</div>

Procedure to get Python Working in XCode 7

Step 1: Setup your Project with a External Build System

Step 1.1: Edit the Project Scheme

Step 2: Specify Python as the executable for the project (shift-command-g) the path should be /usr/bin/python

Step 3: Specify your custom working directory

Step 4: Specify your command line arguments to be the name of your python file. (in this example "test.py")

Step 5: Thankfully thats it!

(debugging can't be added until OSX supports a python debugger?)

If your data is always going to be repeatable, perhaps don't worry about it. However, you can unroll it too - this is especially useful if the incoming data could be large (for example, reading from disk/network):

if(objects == null) throw new ArgumentException();
using(var iter = objects.GetEnumerator()) {
    if(!iter.MoveNext()) throw new ArgumentException();

    var firstObject = iter.Current;
    var list = DoSomeThing(firstObject);  

    while(iter.MoveNext()) {
        list.Add(DoSomeThingElse(iter.Current));
    }
    return list;
}

Note I changed the semantic of DoSomethingElse a bit, but this is mainly to show unrolled usage. You could re-wrap the iterator, for example. You could make it an iterator block too, which could be nice; then there is no list - and you would yield return the items as you get them, rather than add to a list to be returned.

For having hover effect you can simply try this code

import React from "react";
  import "./styles.css";

    export default function App() {

      function MouseOver(event) {
        event.target.style.background = 'red';
      }
      function MouseOut(event){
        event.target.style.background="";
      }
      return (
        <div className="App">
          <button onMouseOver={MouseOver} onMouseOut={MouseOut}>Hover over me!</button>
        </div>
      );
    }

Or if you want to handle this situation using useState() hook then you can try this piece of code

import React from "react";
import "./styles.css";


export default function App() {
   let [over,setOver]=React.useState(false);

   let buttonstyle={
    backgroundColor:''
  }

  if(over){
    buttonstyle.backgroundColor="green";
  }
  else{
    buttonstyle.backgroundColor='';
  }

  return (
    <div className="App">
      <button style={buttonstyle}
      onMouseOver={()=>setOver(true)} 
      onMouseOut={()=>setOver(false)}
      >Hover over me!</button>
    </div>
  );
}

Both of the above code will work for hover effect but first procedure is easier to write and understand

input.next();
String s = input.toString();

change it to

String s = input.next();

May be that's what you were trying to do.

Don't forget to change profile in Provision Profile sections:

Ideally you should see Automatic in Code Signing Identity after you choose provision profile you need. If you don't see any option that's mean you don't have private key for current provision profile.

The only correct way to run python cron jobs when using a virtualenv is to activate the environment and then execute the environment's python to run your code.

One way to do this is use virtualenv's activate_this in your python script, see: http://virtualenv.readthedocs.org/en/latest/userguide.html#using-virtualenv-without-bin-python

Another solution is echoing the complete command including activating the environment and piping it into /bin/bash. Consider this for your /etc/crontab:

***** root echo 'source /env/bin/activate; python /your/script' | /bin/bash

Sets behave different than dicts, you need to use set operations like issubset():

>>> k
{'ip': '123.123.123.123', 'pw': 'test1234', 'port': 1234, 'debug': True}
>>> set('ip,port,pw'.split(',')).issubset(set(k.keys()))
True
>>> set('ip,port,pw'.split(',')) in set(k.keys())
False

I have just figured out something with this error.

Just make sure that the library jar file contains the compiled R class under android.support.v7.appcompat package and copy all the res in the v7 appcompat support "project" in your ANDROID_SDK_HOME/extras/android/support/v7/appcompat folder.

I use Netbeans with the Android plugin and this solved my issue.

You can convert both the values to lower case and compare.

Here is an example:

If LCase(Range("J6").Value) = LCase("Tawi") Then
   Range("J6").Value = "Tawi-Tawi"
End If

• Use a dictionary when you have a set of unique keys that map to values.

• Use a list if you have an ordered collection of items.

• Use a set to store an unordered set of items.

This option is no longer supported in recent versions of karma:

see https://github.com/karma-runner/karma/issues/1731#issuecomment-174227054

The files array can be redefined using the CLI as such:

karma start --files=Array("test/Spec/services/myServiceSpec.js")

or escaped:

karma start --files=Array\(\"test/Spec/services/myServiceSpec.js\"\)

References

• karma-runner source: cli.js

• karma-runner source: config.js

This sort of approach should work.

var plugin_exists = true;

try {
  // some code that requires that plugin here
} catch(err) {
  plugin_exists = false;
}

When I use Junit4, import junit.framework.Assert; import junit.framework.TestCase; the warning info is :The type of Assert is deprecated

when import like this: import org.junit.Assert; import org.junit.Test; the warning has disappeared

As mentioned in my comment to harpo's answer, his solution is good and works in most cases, however in some scenarios when commas as directly adjacent to each other it fails to split on the commas.

This is because of the Regex string behaving unexpectedly as a vertabim string. In order to get this behave correct, all " characters in the regex string need to be escaped manually without using the vertabim escape.

Ie. The regex should be this using manual escapes:

",(?=(?:[^\"\"]*\"\"[^\"\"]*\"\")*(?![^\"\"]*\"\"))"

which translates into ",(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"

When using a vertabim string @",(?=(?:[^""]*""[^""]*"")*(?![^""]*""))" it behaves as the following as you can see if you debug the regex:

",(?=(?:[^"]*"[^"]*")*(?![^"]*"))"

So in summary, I recommend harpo's solution, but watch out for this little gotcha!

I've included into the CsvReader a little optional failsafe to notify you if this error occurs (if you have a pre-known number of columns):

if (_expectedDataLength > 0 && values.Length != _expectedDataLength) 
throw new DataLengthException(string.Format("Expected {0} columns when splitting csv, got {1}", _expectedDataLength, values.Length));

This can be injected via the constructor:

public CsvReader(string fileName, int expectedDataLength = 0) : this(new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
    _expectedDataLength = expectedDataLength;
}

Time::HiRes:

  use Time::HiRes;
  Time::HiRes::sleep(0.1); #.1 seconds

I don’t know for sure but I’m reading a book right now and what I am getting is that a program need to handle its signal ( as when I press CTRL-C). Now a program can use SIG_IGN to ignore all signals or SIG_DFL to restore the default action.

Now if you do $ command & then this process running as background process simply ignores all signals that will occur. For foreground processes these signals are not ignored.

i see here already wrote good answers, but sometime to write the same in other form can be helpful

<div ng-app ng-controller="MyCtrl">
  <select ng-model="referral.organization" ng-options="c for c in organizations"></select>
</div>

<script type='text/javascript'>
  function MyCtrl($scope) {
    $scope.organizations = ['a', 'b', 'c', 'd', 'e'];
    $scope.referral = {
      organization: $scope.organizations[2]
    };
  }
</script>

for n in range(6,0,-1):
    print n

If you have made that request in your application already, and see it logged in Google Dev Tools, you can use the copy cURL command from the context menu when right-clicking on the request in the network tab. Copy -> Copy as cURL. It will contain all headers, cookies, etc..

There are some other ways too. I have used the following script:

$File = "D:\Dev\somefilename.zip";
$ftp = "ftp://username:[email protected]/pub/incoming/somefilename.zip";

Write-Host -Object "ftp url: $ftp";

$webclient = New-Object -TypeName System.Net.WebClient;
$uri = New-Object -TypeName System.Uri -ArgumentList $ftp;

Write-Host -Object "Uploading $File...";

$webclient.UploadFile($uri, $File);

And you could run a script against the windows FTP command line utility using the following command

ftp -s:script.txt 

(Check out this article)

The following question on SO also answers this: How to script FTP upload and download?

It seems there's no way to elevate the application privileges for a while for you to perform a particular task. Windows needs to know at the start of the program whether the application requires certain privileges, and will ask the user to confirm when the application performs any tasks that need those privileges. There are two ways to do this:

1. Write a manifest file that tells Windows the application might require some privileges
2. Run the application with elevated privileges from inside another program

This two articles explain in much more detail how this works.

What I'd do, if you don't want to write a nasty ctypes wrapper for the CreateElevatedProcess API, is use the ShellExecuteEx trick explained in the Code Project article (Pywin32 comes with a wrapper for ShellExecute). How? Something like this:

When your program starts, it checks if it has Administrator privileges, if it doesn't it runs itself using the ShellExecute trick and exits immediately, if it does, it performs the task at hand.

As you describe your program as a "script", I suppose that's enough for your needs.

Cheers.

Another version of Miroslav Zadravec's code, but slightly more automated and universal:

    public Form1()
    {
        InitializeComponent();
        dataGridView1.DataSource = source;
        for (int i = 0; i < dataGridView1.Columns.Count - 1; i++) {
            dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
        }
        dataGridView1.Columns[dataGridView1.Columns.Count].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

    }

    void Form1Shown(object sender, EventArgs e)
    {
        for ( int i = 0; i < dataGridView1.Columns.Count; i++ )
        {
            int colw = dataGridView1.Columns[i].Width;
            dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
            dataGridView1.Columns[i].Width = colw;
        }
    }

I put second part into separate event, because I fill datagridvew in initialization of form and if both parts are there, nothing is changing, because probably autosize calculates widths after datagridview is displayed, so the widths are still default in Form1() method. After finishing this method, autosize does its trick and immediately after that (when form is shown) we can set the widths by second part of the code (here in Form1Shown event). This is working for me like a charm.

You can't cause a .Net application to elevate its own rights. It's simply not allowed. The best you can do is to specify elevated rights when you spawn another process. In this case you would have a two-stage application launch.

Stage 1 does nothing but prepare an elevated spawn using the System.Diagnostics.ProcessStartInfo object and the Start() call.

Stage 2 is the application running in an elevated state.

As mentioned above, though, you very rarely want to do this. And you certainly don't want to do it just so you can write temporary files into %programfiles%. Use this method only when you need to perform administrative actions like service start/stop, etc. Write your temporary files into a better place, as indicated in other answers here.

ArrayList<String> listdata = new ArrayList<String>();     
JSONArray jArray = (JSONArray)jsonObject; 
if (jArray != null) { 
   for (int i=0;i<jArray.length();i++){ 
    listdata.add(jArray.getString(i));
   } 
} 

this will work definately !!!

  $v = Validator::make($request->all(),[
  'name' => ['Required','alpha']
  ]);

   if($v->passes()){
     print_r($request->name);
   }
   else{
     //this will return the errors & to check put "dd($errors);" in your blade(view)
     return back()->withErrors($v)->withInput();
   }

Look in this libraryes for php http://phptrends.com/category/70. Or use native from php http://www.php.net/manual/en/book.sockets.php .

The exact wording of the latest published standard (C++14) is:

An implementation shall allow both

• a function of () returning int and

• a function of (int, pointer to pointer to char) returning int

as the type of main.

This makes it clear that alternative spellings are permitted so long as the type of main is the type int() or int(int, char**). So the following are also permitted:

• int main(void)
• auto main() -> int
• int main ( )
• signed int main()
• typedef char **a; typedef int b, e; e main(b d, a c)

When you check out a tag, you have what's called a "detached head". Normally, Git's HEAD commit is a pointer to the branch that you currently have checked out. However, if you check out something other than a local branch (a tag or a remote branch, for example) you have a "detached head" -- you're not really on any branch. You should not make any commits while on a detached head.

It's okay to check out a tag if you don't want to make any edits. If you're just examining the contents of files, or you want to build your project from a tag, it's okay to git checkout my_tag and work with the files, as long as you don't make any commits. If you want to start modifying files, you should create a branch based on the tag:

$ git checkout -b my_tag_branch my_tag

will create a new branch called my_tag_branch starting from my_tag. It's safe to commit changes on this branch.

With Git 2.22 (Q2 2019), you will have a simpler approach: git branch --show-current.

See commit 0ecb1fc (25 Oct 2018) by Daniels Umanovskis (umanovskis).
^{(Merged by Junio C Hamano -- gitster -- in commit 3710f60, 07 Mar 2019)}

branch: introduce --show-current display option

When called with --show-current, git branch will print the current branch name and terminate.
Only the actual name gets printed, without refs/heads.
In detached HEAD state, nothing is output.

Intended both for scripting and interactive/informative use.
Unlike git branch --list, no filtering is needed to just get the branch name.

See the original discussion on the Git mailing list in Oct. 2018, and the actual pathc.

Have you executed "setup_xampp.bat" script? It's inside XAMPP folder and it must be executed every time you change XAMPP folder.

There are different ways for this:

1.Building C# Applications Using csc.exe

While it is true that you might never decide to build a large-scale application using nothing but the C# command-line compiler, it is important to understand the basics of how to compile your code files by hand.

2.Building .NET Applications Using Notepad++

Another simple text editor I’d like to quickly point out is the freely downloadable Notepad++ application. This tool can be obtained from http://notepad-plus.sourceforge.net. Unlike the primitive Windows Notepad application, Notepad++ allows you to author code in a variety of languages and supports

3.Building .NET Applications Using SharpDevelop

As you might agree, authoring C# code with Notepad++ is a step in the right direction, compared to Notepad. However, these tools do not provide rich IntelliSense capabilities for C# code, designers for building graphical user interfaces, project templates, or database manipulation utilities. To address such needs, allow me to introduce the next .NET development option: SharpDevelop (also known as "#Develop").You can download it from http://www.sharpdevelop.com.

If you need to just empty the style of an element then:
element.style.cssText = null;
This should do good. Hope it helps!

Prior to PHP 7 type hinting can only be used to force the types of objects and arrays. Scalar types are not type-hintable. In this case an object of the class string is expected, but you're giving it a (scalar) string. The error message may be funny, but it's not supposed to work to begin with. Given the dynamic typing system, this actually makes some sort of perverted sense.

You can only manually "type hint" scalar types:

function foo($string) {
    if (!is_string($string)) {
        trigger_error('No, you fool!');
        return;
    }
    ...
}

One more possibility, if you don't want to use ArgumentCaptor (for example, because you're also using stubbing), is to use Hamcrest Matchers in combination with Mockito.

import org.mockito.Mockito
import org.hamcrest.Matchers
...

Mockito.verify(mockedObject).someMethodOnMockedObject(MockitoHamcrest.argThat(
    Matchers.<SomeObjectAsArgument>hasProperty("propertyName", desiredValue)));

If you're not familiar or comfortable with is(), you could just check the value of prop("selected").

As seen here:

$('#mySelectBox option').each(function() {
    if ($(this).prop("selected") == true) {
       // do something
    } else {
       // do something
    }
});?

Edit:

As @gdoron pointed out in the comments, the faster and most appropriate way to access the selected property of an option is via the DOM selector. Here is the fiddle update displaying this action.

if (this.selected == true) {

appears to work just as well! Thanks gdoron.

The Stream API was designed to make it easy to write computations in a way that was abstracted away from how they would be executed, making switching between sequential and parallel easy.

However, just because its easy, doesn't mean its always a good idea, and in fact, it is a bad idea to just drop .parallel() all over the place simply because you can.

First, note that parallelism offers no benefits other than the possibility of faster execution when more cores are available. A parallel execution will always involve more work than a sequential one, because in addition to solving the problem, it also has to perform dispatching and coordinating of sub-tasks. The hope is that you'll be able to get to the answer faster by breaking up the work across multiple processors; whether this actually happens depends on a lot of things, including the size of your data set, how much computation you are doing on each element, the nature of the computation (specifically, does the processing of one element interact with processing of others?), the number of processors available, and the number of other tasks competing for those processors.

Further, note that parallelism also often exposes nondeterminism in the computation that is often hidden by sequential implementations; sometimes this doesn't matter, or can be mitigated by constraining the operations involved (i.e., reduction operators must be stateless and associative.)

In reality, sometimes parallelism will speed up your computation, sometimes it will not, and sometimes it will even slow it down. It is best to develop first using sequential execution and then apply parallelism where

(A) you know that there's actually benefit to increased performance and

(B) that it will actually deliver increased performance.

(A) is a business problem, not a technical one. If you are a performance expert, you'll usually be able to look at the code and determine (B), but the smart path is to measure. (And, don't even bother until you're convinced of (A); if the code is fast enough, better to apply your brain cycles elsewhere.)

The simplest performance model for parallelism is the "NQ" model, where N is the number of elements, and Q is the computation per element. In general, you need the product NQ to exceed some threshold before you start getting a performance benefit. For a low-Q problem like "add up numbers from 1 to N", you will generally see a breakeven between N=1000 and N=10000. With higher-Q problems, you'll see breakevens at lower thresholds.

But the reality is quite complicated. So until you achieve experthood, first identify when sequential processing is actually costing you something, and then measure if parallelism will help.

i have resorted to running PFSense, a BSD based router/firewall to achieve this goal….

why? because OS X Server gets so FREAKY without a Static IP…

so after wrestling with it for DAYS to make NAT and DHCP and firewall and …

I'm trying this is parallels…

will let ya know how it goes...

The easiest way is:

• Find the drop-down box at the top of Visual Studio's window that says Debug
• Select Release
• Hit F6 to build it
• Switch back to Debug and then close Visual Studio
• Open Windows Explorer and navigate to your project's folder (My Documents\Visual Studio 200x\Projects\my_project\)
• Now go to bin\Release\ and copy the executable from there to wherever you want to store it
• Make shortcuts as appropriate and enjoy your new game! :)

If you're using PHP you can test your PUT upload using the code below:

#Initiate cURL object
$curl = curl_init();
#Set your URL
curl_setopt($curl, CURLOPT_URL, 'https://local.simbiat.ru');
#Indicate, that you plan to upload a file
curl_setopt($curl, CURLOPT_UPLOAD, true);
#Indicate your protocol
curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS);
#Set flags for transfer
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
#Disable header (optional)
curl_setopt($curl, CURLOPT_HEADER, false);
#Set HTTP method to PUT
curl_setopt($curl, CURLOPT_PUT, 1);
#Indicate the file you want to upload
curl_setopt($curl, CURLOPT_INFILE, fopen('path_to_file', 'rb'));
#Indicate the size of the file (it does not look like this is mandatory, though)
curl_setopt($curl, CURLOPT_INFILESIZE, filesize('path_to_file'));
#Only use below option on TEST environment if you have a self-signed certificate!!! On production this can cause security issues
#curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
#Execute
curl_exec($curl);

Am going to try and add value to this very good question and to build on @BrittonKerin's question in one of the comments under @David Wolever's fantastic answer. Wanted to share here because I had the same challenge as @BrittonKerin and I got something working (i.e. just want to run a piece of code only IF the table doesn't exist).

        # for completeness lets do the routine thing of connections and cursors
        conn = sqlite3.connect(db_file, timeout=1000) 

        cursor = conn.cursor() 

        # get the count of tables with the name  
        tablename = 'KABOOM' 
        cursor.execute("SELECT count(name) FROM sqlite_master WHERE type='table' AND name=? ", (tablename, ))

        print(cursor.fetchone()) # this SHOULD BE in a tuple containing count(name) integer.

        # check if the db has existing table named KABOOM
        # if the count is 1, then table exists 
        if cursor.fetchone()[0] ==1 : 
            print('Table exists. I can do my custom stuff here now.... ')
            pass
        else: 
           # then table doesn't exist. 
           custRET = myCustFunc(foo,bar) # replace this with your custom logic

Use the format() function with a '02x' format.

>>> format(255, '02x')
'ff'
>>> format(2, '02x')
'02'

The 02 part tells format() to use at least 2 digits and to use zeros to pad it to length, x means lower-case hexadecimal.

The Format Specification Mini Language also gives you X for uppercase hex output, and you can prefix the field width with # to include a 0x or 0X prefix (depending on wether you used x or X as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:

>>> format(255, '02X')
'FF'
>>> format(255, '#04x')
'0xff'
>>> format(255, '#04X')
'0XFF'

Global variables can be used in Node when used wisely.

Declaration of global variables in Node:

a = 10;
GLOBAL.a = 10;
global.a = 10;

All of the above commands the same actions with different syntaxes.

Use global variables when they are not about to be changed

Here an example of something that can happen when using global variables:

// app.js
a = 10; // no var or let or const means global

// users.js
app.get("/users", (req, res, next) => {
   res.send(a); // 10;
});

// permissions.js
app.get("/permissions", (req, res, next) => {
   a = 11; // notice that there is no previous declaration of a in the permissions.js, means we looking for the global instance of a.
   res.send(a); // 11;
});

Explained:

Run users route first and receive 10;

Then run permissions route and receive 11;

Then run again the users route and receive 11 as well instead of 10;

Global variables can be overtaken!

Now think about using express and assignin res object as global.. And you end up with async error become corrupt and server is shuts down.

When to use global vars?

As I said - when var is not about to be changed. Anyways it's more recommended that you will be using the process.env object from the config file.

If you have this setup

/app
   /public/index.html
   /media

Then this should get what you wanted

var express = require('express');
//var server = express.createServer();
// express.createServer()  is deprecated. 
var server = express(); // better instead
server.configure(function(){
  server.use('/media', express.static(__dirname + '/media'));
  server.use(express.static(__dirname + '/public'));
});

server.listen(3000);

The trick is leaving this line as last fallback

  server.use(express.static(__dirname + '/public'));

As for documentation, since Express uses connect middleware, I found it easier to just look at the connect source code directly.

For example this line shows that index.html is supported https://github.com/senchalabs/connect/blob/2.3.3/lib/middleware/static.js#L140

This is a simple way to test this for the current page URL:

  function checkHash(){
      return (location.hash ? true : false);
  }

From the WordPress Codex:

<?php
$the_slug = 'my_slug';
$args = array(
  'name'        => $the_slug,
  'post_type'   => 'post',
  'post_status' => 'publish',
  'numberposts' => 1
);
$my_posts = get_posts($args);
if( $my_posts ) :
  echo 'ID on the first post found ' . $my_posts[0]->ID;
endif;
?>

I think you are trying to toggle the disabled state, in witch case you should use this (from this question):

$(".inputDisabled").prop('disabled', function (_, val) { return ! val; });

Here is a working fiddle.

Try this: return (((a>>1)<<1) == a)

Example:

a     =  10101011
-----------------
a>>1 --> 01010101
a<<1 --> 10101010

b     =  10011100
-----------------
b>>1 --> 01001110
b<<1 --> 10011100

try jQueryTimers, they have great functionality for polling

By using Reflector, you can see, that Contains is implemented using IndexOf. Here's the implementation.

public bool Contains(string value)
{
   return (this.IndexOf(value, StringComparison.Ordinal) >= 0);
}

So Contains is likely a wee bit slower than calling IndexOf directly, but I doubt that it will have any significance for the actual performance.

I understood that you want to remove from the array using a condition and have another array that has items removed from the array. Is right?

How about this?

var review = ['a', 'b', 'c', 'ab', 'bc'];_x000D_
var filtered = [];_x000D_
for(var i=0; i < review.length;) {_x000D_
  if(review[i].charAt(0) == 'a') {_x000D_
    filtered.push(review.splice(i,1)[0]);_x000D_
  }else{_x000D_
    i++;_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log("review", review);_x000D_
console.log("filtered", filtered);

Hope this help...

By the way, I compared 'for-loop' to 'forEach'.

If remove in case a string contains 'f', a result is different.

var review = ["of", "concat", "copyWithin", "entries", "every", "fill", "filter", "find", "findIndex", "flatMap", "flatten", "forEach", "includes", "indexOf", "join", "keys", "lastIndexOf", "map", "pop", "push", "reduce", "reduceRight", "reverse", "shift", "slice", "some", "sort", "splice", "toLocaleString", "toSource", "toString", "unshift", "values"];_x000D_

    filtered.push(review.splice(i,1)[0]);_x000D_
  }else {_x000D_
    i++;_x000D_

_x000D_
console.log("========================================================");_x000D_

filtered = [];_x000D_
_x000D_
review.forEach(function(item,i, object) {_x000D_
  if( item.includes('f')) {_x000D_
    filtered.push(object.splice(i,1)[0]);_x000D_
  }_x000D_
});_x000D_
_x000D_
console.log("-----------------------------------------");_x000D_

 */

And remove by each iteration, also a result is different.

var review = ["of", "concat", "copyWithin", "entries", "every", "fill", "filter", "find", "findIndex", "flatMap", "flatten", "forEach", "includes", "indexOf", "join", "keys", "lastIndexOf", "map", "pop", "push", "reduce", "reduceRight", "reverse", "shift", "slice", "some", "sort", "splice", "toLocaleString", "toSource", "toString", "unshift", "values"];_x000D_
