There is another way to pristine form that is by sending form into the controller. For example:-

In view:-

<form name="myForm" ng-submit="addUser(myForm)" novalidate>
    <input type="text" ng-mode="user.name"/>
     <span style="color:red" ng-show="myForm.name.$dirty && myForm.name.$invalid">
      <span ng-show="myForm.name.$error.required">Name is required.</span>
    </span>

    <button ng-disabled="myForm.$invalid">Add User</button>
</form>

In Controller:-

$scope.addUser = function(myForm) {
       myForm.$setPristine();
};

If it's the first time for you to save your datatable

Do this (using bulk copy). Assure there are no PK/FK constraint

SqlBulkCopy bulkcopy = new SqlBulkCopy(myConnection);
//I assume you have created the table previously
//Someone else here already showed how  
bulkcopy.DestinationTableName = table.TableName;
try                             
{                                 
    bulkcopy.WriteToServer(table);                            
}     
    catch(Exception e)
{
    messagebox.show(e.message);
} 

Now since you already have a basic record. And you just want to check new record with the existing one. You can simply do this.

This will basically take existing table from database

DataTable Table = new DataTable();

SqlConnection Connection = new SqlConnection("ConnectionString");
//I assume you know better what is your connection string

SqlDataAdapter adapter = new SqlDataAdapter("Select * from " + TableName, Connection);

adapter.Fill(Table);

Then pass this table to this function

public DataTable CompareDataTables(DataTable first, DataTable second)
{
    first.TableName = "FirstTable";
    second.TableName = "SecondTable";

    DataTable table = new DataTable("Difference");

    try
    {
        using (DataSet ds = new DataSet())
        {
            ds.Tables.AddRange(new DataTable[] { first.Copy(), second.Copy() });

            DataColumn[] firstcolumns = new DataColumn[ds.Tables[0].Columns.Count];

            for (int i = 0; i < firstcolumns.Length; i++)
            {
                firstcolumns[i] = ds.Tables[0].Columns[i];
            }

            DataColumn[] secondcolumns = new DataColumn[ds.Table[1].Columns.Count];

            for (int i = 0; i < secondcolumns.Length; i++)
            {
                secondcolumns[i] = ds.Tables[1].Columns[i];
            }

            DataRelation r = new DataRelation(string.Empty, firstcolumns, secondcolumns, false);

            ds.Relations.Add(r);

            for (int i = 0; i < first.Columns.Count; i++)
            {
                table.Columns.Add(first.Columns[i].ColumnName, first.Columns[i].DataType);
            }

            table.BeginLoadData();

            foreach (DataRow parentrow in ds.Tables[0].Rows)
            {
                DataRow[] childrows = parentrow.GetChildRows(r);
                if (childrows == null || childrows.Length == 0)
                    table.LoadDataRow(parentrow.ItemArray, true);
            }

            table.EndLoadData();

        }
    }

    catch (Exception ex)
    {
        throw ex;
    }

    return table;
}

This will return a new DataTable with the changed rows updated. Please ensure you call the function correctly. The DataTable first is supposed to be the latest.

Then repeat the bulkcopy function all over again with this fresh datatable.

1. The one-way data binding is an approach where a value is taken from the data model and inserted into an HTML element. There is no way to update model from view. It is used in classical template systems. These systems bind data in only one direction.

2. Data-binding in Angular apps is the automatic synchronisation of data between the model and view components.

Data binding lets you treat the model as the single-source-of-truth in your application. The view is a projection of the model at all times. If the model is changed, the view reflects the change and vice versa.

Redirection of program output is performed by the shell.

grep ... > output.txt

grep has no mechanism for adding blank lines between each match, but does provide options such as context around the matched line and colorization of the match itself. See the grep(1) man page for details, specifically the -C and --color options.

Use the strpos function: http://php.net/manual/en/function.strpos.php

$haystack = "foo bar baz";
$needle   = "bar";

if( strpos( $haystack, $needle ) !== false) {
    echo "\"bar\" exists in the haystack variable";
}

In your case:

if( strpos( $a, 'some text' ) !== false ) echo 'text';

Note that my use of the !== operator (instead of != false or == true or even just if( strpos( ... ) ) {) is because of the "truthy"/"falsy" nature of PHP's handling of the return value of strpos.

As of PHP 8.0.0 you can now use str_contains

<?php
    if (str_contains('abc', '')) {
        echo "Checking the existence of the empty string will always 
        return true";
    }

The bearing calculation is incorrect, you need to swap the inputs to atan2.

    bearing = atan2(sin(long2-long1)*cos(lat2), cos(lat1)*sin(lat2)-sin(lat1)*cos(lat2)*cos(long2-long1))
    bearing = degrees(bearing)
    bearing = (bearing + 360) % 360

This will give you the correct bearing.

If you pass the -v flag to ansible-playbook on the command line, you'll see the stdout and stderr for each task executed:

$ ansible-playbook -v playbook.yaml

Ansible also has built-in support for logging. Add the following lines to your ansible configuration file:

[defaults] 
log_path=/path/to/logfile

Ansible will look in several places for the config file:

• ansible.cfg in the current directory where you ran ansible-playbook
• ~/.ansible.cfg
• /etc/ansible/ansible.cfg

The updatePolicy tag didn't work for me. However Rich Seller mentioned that snapshots should be disabled anyways so I looked further and noticed that the extra repository that I added to my settings.xml was causing the problem actually. Adding the snapshots section to this repository in my settings.xml did the trick!

<repository>
    <id>jboss</id>
    <name>JBoss Repository</name>
    <url>http://repository.jboss.com/maven2</url>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
</repository>

What you want to do is really important for unit testing. Basically you need to create a small local function in the view controller. Name the function anything, just include the performSegueWithIndentifier.

func localFunc() {
    println("we asked you to do it")
    performSegueWithIdentifier("doIt", sender: self)
}

Next change your utility class FBManager to include an initializer that takes an argument of a function and a variable to hold the ViewController's function that performs the segue.

public class UtilClass {

    var yourFunction : () -> ()

    init (someFunction: () -> ()) {
        self.yourFunction = someFunction
        println("initialized UtilClass")
    }

    public convenience init() {
        func dummyLog () -> () {
            println("no action passed")
        }
        self.init(dummyLog)
    }

    public func doThatThing() -> () {
        // the facebook login function
        println("now execute passed function")
        self.yourFunction()
        println("did that thing")
    }
}

(The convenience init allows you to use this in unit testing without executing the segue.)

Finally, where you have //todo: segue to the next view???, put something along the lines of:

self.yourFunction()

In your unit tests, you can simply invoke it as:

let f = UtilClass()
f.doThatThing()

where doThatThing is your fbsessionstatechange and UtilClass is FBManager.

For your actual code, just pass localFunc (no parenthesis) to the FBManager class.

In Node.js, you can use Path's parse module...

var path = require('path');
var file = '/home/user/dir/file.txt';

var filename = path.parse(file).base;
//=> 'file.txt'

First You have to inject HttpClient and Not HttpClientModule, second thing you have to remove .map((res:any) => res.json()) you won't need it any more because the new HttpClient will give you the body of the response by default , finally make sure that you import HttpClientModule in your AppModule :

import { HttpClient } from '@angular/common/http'; 
import { Observable } from 'rxjs';

@Injectable()
export class AppSettingsService {

   constructor(private http: HttpClient) {
        this.getJSON().subscribe(data => {
            console.log(data);
        });
    }

    public getJSON(): Observable<any> {
        return this.http.get("./assets/mydata.json");
    }
}

to add this to your Component:

@Component({
    selector: 'mycmp',
    templateUrl: 'my.component.html',
    styleUrls: ['my.component.css']
})
export class MyComponent implements OnInit {
    constructor(
        private appSettingsService : AppSettingsService 
    ) { }

   ngOnInit(){
       this.appSettingsService.getJSON().subscribe(data => {
            console.log(data);
        });
   }
}

Swift 4.1 and Swift 5. The updatetime method will called after every second and seconds will display on UIlabel.

     var timer: Timer?
     var totalTime = 60
    
     private func startOtpTimer() {
            self.totalTime = 60
            self.timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(updateTimer), userInfo: nil, repeats: true)
        }
    
    @objc func updateTimer() {
            print(self.totalTime)
            self.lblTimer.text = self.timeFormatted(self.totalTime) // will show timer
            if totalTime != 0 {
                totalTime -= 1  // decrease counter timer
            } else {
                if let timer = self.timer { 
                    timer.invalidate()
                    self.timer = nil
                }
            }
        }
    func timeFormatted(_ totalSeconds: Int) -> String {
        let seconds: Int = totalSeconds % 60
        let minutes: Int = (totalSeconds / 60) % 60
        return String(format: "%02d:%02d", minutes, seconds)
    }

Because this seems to not be marked as answered yet... The Answer of Thomas Arildsen should be the proper one: just use

np.flipud(your_array) 

if it is a 1d array (column array).

With matrizes do

fliplr(matrix)

if you want to reverse rows and flipud(matrix) if you want to flip columns. No need for making your 1d column array a 2dimensional row array (matrix with one None layer) and then flipping it.

I were coming from C# to java and had the same problem and the best and exact alternative for region is something like below (working in Android Studio, dont know about intelliJ):

 //region [Description]
 int a;
 int b;
 int c;
//endregion

the shortcut is like below:

1- select the code

2- press ctrl + alt + t

3- press c and write your description

Better and quicker approach without any software to download.

• Open command prompt and follow steps mentioned below
• cd path/from/where/file/istobe/copied
• ftp (serverip or name)
• It will ask for Server(AIX) User: (username)
• It will ask for password : (password)
• cd path/where/file/istobe/copied
• pwd (to check current path)
• mput (directory name which is to be copied)

This should work.

Now you can use the aggregate. Example:

db.users.aggregate(
   [ { $sample: { size: 3 } } ]
)

See the doc.

For those of you that have HTC Sync installed, uninstalling the application fixed this problem for me.

Like this:

int counts[26];
memset(counts, 0, sizeof(counts));
char *p = string;
while (*p) {
    counts[tolower(*p++) - 'a']++;
}

This code assumes that the string is null-terminated, and that it contains only characters a through z or A through Z, inclusive.

To understand how this works, recall that after conversion tolower each letter has a code between a and z, and that the codes are consecutive. As the result, tolower(*p) - 'a' evaluates to a number from 0 to 25, inclusive, representing the letter's sequential number in the alphabet.

This code combines ++ and *p to shorten the program.

Wasn't sure if you meant which Oracle users can read\write with the directory or the correlation of the permissions between Oracle Directory Object and the underlying Operating System Directory.

As DCookie has covered the Oracle side of the fence, the following is taken from the Oracle documentation found here.

Privileges granted for the directory are created independently of the permissions defined for the operating system directory, and the two may or may not correspond exactly. For example, an error occurs if sample user hr is granted READ privilege on the directory object but the corresponding operating system directory does not have READ permission defined for Oracle Database processes.

This approach works well:

gci C:\Projects *.config -recurse | ForEach {
  (Get-Content $_ | ForEach {$_ -replace "old", "new"}) | Set-Content $_ 
}

• Change "old" and "new" to their corresponding values (or use variables).
• Don't forget the parenthesis -- without which you will receive an access error.

I would like to add my answer even though this thread is years old and it ranked high in Google for me.

My best method is to try:

if(sizeof($_POST) !== 0){
// Code...
}

As $_POST is an array, if the script loads and no data is present in the $_POST variable it will have an array length of 0. This can be used in an IF statement.

You may also be wondering if this throws an "undefined index" error seeing as though we're checking if $_POST is set... In fact $_POST always exists, the "undefined index" error will only appear if you try to search for a $_POST array value that doesn't exist.

$_POST always exists in itself being either empty or has array values. $_POST['value'] may not exist, thus throwing an "undefined index" error.

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

image view add as a sub view to the tableview cell

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:8.0f];
[imgView.layer setMasksToBounds:YES];
[imgView setImage:[UIImage imageWithData: imageData]];
[cell.contentView addSubview:imgView];

I use abline() with extremely wide vertical lines to fill the plot space:

abline(v = xpoints, col = "grey90", lwd = 80)

You have to create the frame, then the ablines, and then plot the points so they are visible on top. You can even use a second abline() statement to put thin white or black lines over the grey, if desired.

Example:

xpoints = 1:20
y = rnorm(20)
plot(NULL,ylim=c(-3,3),xlim=xpoints)
abline(v=xpoints,col="gray90",lwd=80)
abline(v=xpoints,col="white")
abline(h = 0, lty = 2) 
points(xpoints, y, pch = 16, cex = 1.2, col = "red")

String.Format adds many options in addition to the concatenation operators, including the ability to specify the specific format of each item added into the string.

For details on what is possible, I'd recommend reading the section on MSDN titled Composite Formatting. It explains the advantage of String.Format (as well as xxx.WriteLine and other methods that support composite formatting) over normal concatenation operators.

to load a KeyStore, you'll need to tell it the type of keystore it is (probably jceks), provide an inputstream, and a password. then, you can load it like so:

KeyStore ks  = KeyStore.getInstance(TYPE_OF_KEYSTORE);
ks.load(new FileInputStream(PATH_TO_KEYSTORE), PASSWORD);

this can throw a KeyStoreException, so you can surround in a try block if you like, or re-throw. Keep in mind a keystore can contain multiple keys, so you'll need to look up your key with an alias, here's an example with a symmetric key:

SecretKeyEntry entry = (KeyStore.SecretKeyEntry)ks.getEntry(SOME_ALIAS,new KeyStore.PasswordProtection(SOME_PASSWORD));
SecretKey someKey = entry.getSecretKey();

i just place one image in " d drive-->Data-->IMG". The image name is x.jpg:

And on c# code type

ImageBrush myBrush = new ImageBrush();

myBrush.ImageSource = new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), "D:\\Data\\IMG\\x.jpg"));

(please put double slash in between path)

this.Background = myBrush;

finally i got the background..

The only working solution for me, was to define the data object in the geom_line instead of the base object, ggplot.

Like this:

ggplot() + 
geom_line(data=Data1, aes(x=A, y=B), color='green') + 
geom_line(data=Data2, aes(x=C, y=D), color='red')

instead of

ggplot(data=Data1, aes(x=A, y=B), color='green') + 
geom_line() + 
geom_line(data=Data2, aes(x=C, y=D), color='red')

More info here

for the entire line

^(\w+)\s+(\w+)\s+(\d+(?:\/\d+){2})\s+(\w+)$

Not perfect but close:

newcol<-sapply(rownames(t), function(rn){z[match(rn, rownames(z)), 5]})
cbind(data.frame(t), newcol)

If your host not at pvn or dedicated, it's dificult to restart server.

Better solution from me, just edit your CSS file (at another domain or your subdomain) that call font eot, woff etc to your origin (your-domain or www yourdomain). it will solve your problem.

I mean, edit relative url on css to absolute url origin domain

What about CassandraDB, Project Voldemort, TokyoCabinet?

There are quite a few ways to work with dynamic arrays in PHP. Initialise an array:

$array = array();

Add to an array:

$array[] = "item"; // for your $arr1 
$array[$key] = "item"; // for your $arr2
array_push($array, "item", "another item");

Remove from an array:

$item = array_pop($array);
$item = array_shift($array);
unset($array[$key]);

There are plenty more ways, these are just some examples.

I found that applying the -webkit-backface-visibility: hidden; to the translating element and -webkit-transform: translate3d(0,0,0); to all its children, the flicker then disappears

JQuery UI already has this, in my example below I included a maxchar attribute to focus on the next focus-able element (input, select, textarea, button and object) if i typed in the max number of characters

HTML:

text 1 <input type="text" value="" id="txt1" maxchar="5" /><br />
text 2 <input type="text" value="" id="txt2" maxchar="5" /><br />
checkbox 1 <input type="checkbox" value="" id="chk1" /><br />
checkbox 2 <input type="checkbox" value="" id="chk2" /><br />
dropdown 1 <select id="dd1" >
    <option value="1">1</option>
    <option value="1">2</option>
</select><br />
dropdown 2 <select id="dd2">
    <option value="1">1</option>
    <option value="1">2</option>
</select>

Javascript:

$(function() {
    var focusables = $(":focusable");   
    focusables.keyup(function(e) {
        var maxchar = false;
        if ($(this).attr("maxchar")) {
            if ($(this).val().length >= $(this).attr("maxchar"))
                maxchar = true;
            }
        if (e.keyCode == 13 || maxchar) {
            var current = focusables.index(this),
                next = focusables.eq(current+1).length ? focusables.eq(current+1) : focusables.eq(0);
            next.focus();
        }
    });
});

In your AsyncTask add one ProgressDialog like:

private final ProgressDialog dialog = new ProgressDialog(YourActivity.this);

you can setMessage in onPreExecute() method like:

this.dialog.setMessage("Processing..."); 
this.dialog.show();

and in your onPostExecute(Void result) method dismiss your ProgressDialog.

There is a Headers property in the HttpRequestMessage class. You can add custom headers there, which will be sent with each HTTP request. The DefaultRequestHeaders in the HttpClient class, on the other hand, sets headers to be sent with each request sent using that client object, hence the name Default Request Headers.

Hope this makes things more clear, at least for someone seeing this answer in future.

var gulp = require('gulp');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');

gulp.task('create-vendor', function () {
var files = [
    'bower_components/q/q.js',
    'bower_components/moment/min/moment-with-locales.min.js',
    'node_modules/jstorage/jstorage.min.js'
];

return gulp.src(files)
    .pipe(concat('vendor.js'))
    .pipe(gulp.dest('scripts'))
    .pipe(uglify())
    .pipe(gulp.dest('scripts'));
});

Your solution does not work because you need to save file after concat process and then uglify and save again. You do not need to rename file between concat and uglify.

bsondump collection.bson > collection.json

and then

mongoimport -d <dbname> -c <collection> < collection.json

My kotlin entension function for this purpose

fun Context.canPerformIntent(intent: Intent): Boolean {
        val mgr = this.packageManager
        val list = mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
        return list.size > 0
    }

And in your activity

val uri = if (canPerformIntent(Intent(Intent.ACTION_VIEW, Uri.parse("market://")))) {
            Uri.parse("market://details?id=" + appPackageName)
        } else {
            Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)
        }
        startActivity(Intent(Intent.ACTION_VIEW, uri))

Did you actually set up your specific user? The walkthrough setup guide in AWS explains how to set a default user, and then how to set up additional users. If you didn't complete the full setup, you'll just have a default block and your myName won't have been created..

var FD = new System.Windows.Forms.OpenFileDialog();
if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
    string fileToOpen = FD.FileName;

    System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);

    //OR

    System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
    //etc
}

If the position of the line (line number) stays the same through the history of the file, this will show you the contents of the line at each commit:

git log --follow --pretty=format:"%h" -- 'path/to/file' | while read -r hash; do echo $hash && git show $hash:'path/to/file' | head -n 544 | tail -n1; done

Change 544 to the line number and path/to/file to the file path.

In Skype:

Go to Tools ? Options ? Advanced ? Connections and uncheck the box use port 80 and 443 as alternative. This should help.

As Salman Quader said: In the updated skype(8.x), there is no menu option to change the port. This means this answer is no longer valid.

Not really a reliable method, better of using JodaTime

  Calendar thatDay = Calendar.getInstance();
  thatDay.set(Calendar.DAY_OF_MONTH,25);
  thatDay.set(Calendar.MONTH,7); // 0-11 so 1 less
  thatDay.set(Calendar.YEAR, 1985);

  Calendar today = Calendar.getInstance();

  long diff = today.getTimeInMillis() - thatDay.getTimeInMillis(); //result in millis

Here's an approximation...

long days = diff / (24 * 60 * 60 * 1000);

To Parse the date from a string, you could use

  String strThatDay = "1985/08/25";
  SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd");
  Date d = null;
  try {
   d = formatter.parse(strThatDay);//catch exception
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } 


  Calendar thatDay = Calendar.getInstance();
  thatDay.setTime(d); //rest is the same....

Although, since you're sure of the date format... You Could also do Integer.parseInt() on it's Substrings to obtain their numeric values.

Before the command clickAndWait add the following code so the script will wait until the specific link to be visible:

   <tr>
        <td>waitForVisible</td>
        <td>link=do something</td>
        <td></td>
    </tr>

The practice of using the wait commands instead of pause is most of the times more efficient and more stable.

It's creating the file in the same directory as your script. Try this instead.

$content = "some text here";
$fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/myText.txt","wb");
fwrite($fp,$content);
fclose($fp);

Depends on what the while loop is doing. If there is a chance that it will block for a long time, use TimerTask to schedule a task to set a stopExecution flag, and also .interrupt() your thread.

With just a time condition in the loop, it could sit there forever waiting for input or a lock (then again, may not be a problem for you).

Use your file browser and copy-paste the IInAppBillingService.aidl into /app/src/main/aidl/com/android/vending/billing/

I'd suggest 3 things in the beginning of your script:

First, as already being said use environment:

#!/usr/bin/env python

Second, set your encoding:

# -*- coding: utf-8 -*-

Third, set some doc string:

"""This is a awesome
    python script!"""

And for sure I would use " " (4 spaces) for ident.
Final header will look like:

Best wishes and happy coding.

That will only work for small numbers and I'm guessing it's also implementation-dependent. Python uses the same object instance for small numbers (iirc <256), but this changes for bigger numbers.

>>> a = 2104214124
>>> b = 2104214124
>>> a == b
True
>>> a is b
False

So you should always use == to compare numbers.

Ran into the same issue with Web API and .Net Core Web API. Worked fine in VS 2017 while debugging, but returned 404 when published to IIS 7.5. Solution for me was to change the way I created the site. Instead of publishing to the root of a Web Site (created by right clicking Sites...Add Web Site), I had to create an Application (created by right clicking a Web Site...Add Application) and publish to that folder. Note that for the Core version, I had to change the Application Pool .NET Framework Version setting to "No Managed Code".

The nature of wanting to include the row where A == 5 and all rows upto but not including the row where A == 8 means we will end up using iloc (loc includes both ends of slice).

In order to get the index labels we use idxmax. This will return the first position of the maximum value. I run this on a boolean series where A == 5 (then when A == 8) which returns the index value of when A == 5 first happens (same thing for A == 8).

Then I use searchsorted to find the ordinal position of where the index label (that I found above) occurs. This is what I use in iloc.

i5, i8 = df.index.searchsorted([df.A.eq(5).idxmax(), df.A.eq(8).idxmax()])
df.iloc[i5:i8]

numpy

you can further enhance this by using the underlying numpy objects the analogous numpy functions. I wrapped it up into a handy function.

def find_between(df, col, v1, v2):
    vals = df[col].values
    mx1, mx2 = (vals == v1).argmax(), (vals == v2).argmax()
    idx = df.index.values
    i1, i2 = idx.searchsorted([mx1, mx2])
    return df.iloc[i1:i2]

find_between(df, 'A', 5, 8)

The -s option of read is not defined in the POSIX standard. See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html. I wanted something that would work for any POSIX shell, so I wrote a little function that uses stty to disable echo.

#!/bin/sh

# Read secret string
read_secret()
{
    # Disable echo.
    stty -echo

    # Set up trap to ensure echo is enabled before exiting if the script
    # is terminated while echo is disabled.
    trap 'stty echo' EXIT

    # Read secret.
    read "$@"

    # Enable echo.
    stty echo
    trap - EXIT

    # Print a newline because the newline entered by the user after
    # entering the passcode is not echoed. This ensures that the
    # next line of output begins at a new line.
    echo
}

This function behaves quite similar to the read command. Here is a simple usage of read followed by similar usage of read_secret. The input to read_secret appears empty because it was not echoed to the terminal.

[susam@cube ~]$ read a b c
foo \bar baz \qux
[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=bar c=baz qux
[susam@cube ~]$ unset a b c
[susam@cube ~]$ read_secret a b c

[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=bar c=baz qux
[susam@cube ~]$ unset a b c

Here is another that uses the -r option to preserve the backslashes in the input. This works because the read_secret function defined above passes all arguments it receives to the read command.

[susam@cube ~]$ read -r a b c
foo \bar baz \qux
[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=\bar c=baz \qux
[susam@cube ~]$ unset a b c
[susam@cube ~]$ read_secret -r a b c

[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=\bar c=baz \qux
[susam@cube ~]$ unset a b c

Finally, here is an example that shows how to use the read_secret function to read a password in a POSIX compliant manner.

printf "Password: "
read_secret password
# Do something with $password here ...

Use the Git GUI in the Git plugin.

Clone your online repository with the URL which you have.

After cloning, make changes to the files. When you make changes, you can see the number changes. Commit those changes.

Fetch from the remote (to check if anything is updated while you are working).

If the fetch operation gives you an update about the changes in the remote repository, make a pull operation which will update your copy in Visual Studio Code. Otherwise, do not make a pull operation if there aren't any changes in the remote repository.

Push your changes to the upstream remote repository by making a push operation.

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

I created a C++ open source project for normally distributed random number generation benchmark.

It compares several algorithms, including

• Central limit theorem method
• Box-Muller transform
• Marsaglia polar method
• Ziggurat algorithm
• Inverse transform sampling method.
• cpp11random uses C++11 std::normal_distribution with std::minstd_rand (it is actually Box-Muller transform in clang).

The results of single-precision (float) version on iMac [email protected] , clang 6.1, 64-bit:

For correctness, the program verifies the mean, standard deviation, skewness and kurtosis of the samples. It was found that CLT method by summing 4, 8 or 16 uniform numbers do not have good kurtosis as the other methods.

Ziggurat algorithm has better performance than the others. However, it does not suitable for SIMD parallelism as it needs table lookup and branches. Box-Muller with SSE2/AVX instruction set is much faster (x1.79, x2.99) than non-SIMD version of ziggurat algorithm.

Therefore, I will suggest using Box-Muller for architecture with SIMD instruction sets, and may be ziggurat otherwise.

P.S. the benchmark uses a simplest LCG PRNG for generating uniform distributed random numbers. So it may not be sufficient for some applications. But the performance comparison should be fair because all implementations uses the same PRNG, so the benchmark mainly tests the performance of the transformation.

There are lots of data types you can mention while creating model, some examples are:

:primary_key, :string, :text, :integer, :float, :decimal, :datetime, :timestamp, :time, :date, :binary, :boolean, :references

syntax:

field_type:data_type

If an Activity calls onPause with a normal broadcast, receiving the Broadcast can be missed. A sticky broadcast can be checked after it was initiated in onResume.

Update 6/23/2020

Sticky broadcasts are deprecated.

See sendStickyBroadcast documentation.

This method was deprecated in API level 21.

Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that something has changed, with another mechanism for apps to retrieve the current value whenever desired.

Implement

Intent intent = new Intent("some.custom.action");
intent.putExtra("some_boolean", true);
sendStickyBroadcast(intent);

For those who use Github, they have a branch network viewer that seems easier to read

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

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

Forever, by default, will put logs into a random file in ~/.forever/ folder.

You should run forever list to see the running processes and their corresponding log file.

Sample output

>>> forever list
info:    Forever processes running
data:        uid  command       script forever pid  logfile                         uptime

However, it's probably best to specify with -l as mentioned by bryanmac.

The ability to search commits has recently been added to GitHub.

To search for a hash, just enter at least the first 7 characters in the search box. Then on the results page, click the "Commits" tab to see matching commits (but only on the default branch, usually master), or the "Issues" tab to see pull requests containing the commit.

To be more explicit you can add the hash: prefix to the search, but it's not really necessary.

There is also a REST API (at the time of writing it is still in preview).

I face the same issues recently, to solve this problem(simple and fast algorithm to compare two images) once and for all, I contribute an img_hash module to opencv_contrib, you can find the details from this link.

img_hash module provide six image hash algorithms, quite easy to use.

Codes example

origin lena

blur lena

resize lena

shift lena

#include <opencv2/core.hpp>
#include <opencv2/core/ocl.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/img_hash.hpp>
#include <opencv2/imgproc.hpp>

#include <iostream>

void compute(cv::Ptr<cv::img_hash::ImgHashBase> algo)
{
    auto input = cv::imread("lena.png");
    cv::Mat similar_img;

    //detect similiar image after blur attack
    cv::GaussianBlur(input, similar_img, {7,7}, 2, 2);
    cv::imwrite("lena_blur.png", similar_img);
    cv::Mat hash_input, hash_similar;
    algo->compute(input, hash_input);
    algo->compute(similar_img, hash_similar);
    std::cout<<"gaussian blur attack : "<<
               algo->compare(hash_input, hash_similar)<<std::endl;

    //detect similar image after shift attack
    similar_img.setTo(0);
    input(cv::Rect(0,10, input.cols,input.rows-10)).
            copyTo(similar_img(cv::Rect(0,0,input.cols,input.rows-10)));
    cv::imwrite("lena_shift.png", similar_img);
    algo->compute(similar_img, hash_similar);
    std::cout<<"shift attack : "<<
               algo->compare(hash_input, hash_similar)<<std::endl;

    //detect similar image after resize
    cv::resize(input, similar_img, {120, 40});
    cv::imwrite("lena_resize.png", similar_img);
    algo->compute(similar_img, hash_similar);
    std::cout<<"resize attack : "<<
               algo->compare(hash_input, hash_similar)<<std::endl;
}

int main()
{
    using namespace cv::img_hash;

    //disable opencl acceleration may(or may not) boost up speed of img_hash
    cv::ocl::setUseOpenCL(false);

    //if the value after compare <= 8, that means the images
    //very similar to each other
    compute(ColorMomentHash::create());

    //there are other algorithms you can try out
    //every algorithms have their pros and cons
    compute(AverageHash::create());
    compute(PHash::create());
    compute(MarrHildrethHash::create());
    compute(RadialVarianceHash::create());
    //BlockMeanHash support mode 0 and mode 1, they associate to
    //mode 1 and mode 2 of PHash library
    compute(BlockMeanHash::create(0));
    compute(BlockMeanHash::create(1));
}

In this case, ColorMomentHash give us best result

• gaussian blur attack : 0.567521
• shift attack : 0.229728
• resize attack : 0.229358

Pros and cons of each algorithm

The performance of img_hash is good too

Speed comparison with PHash library(100 images from ukbench)

If you want to know the recommend thresholds for these algorithms, please check this post(http://qtandopencv.blogspot.my/2016/06/introduction-to-image-hash-module-of.html). If you are interesting about how do I measure the performance of img_hash modules(include speed and different attacks), please check this link(http://qtandopencv.blogspot.my/2016/06/speed-up-image-hashing-of-opencvimghash.html).

Every time you upgrade or re install a new version of PostgreSQL, a latest version of pg_dump is installed.

There must be a PostgreSQL/bin directory somewhere on your system, under the latest version of PostgreSQL that you've installed ( 9.2.1 is latest) and try running the pg_dump from in there.

Did you setup PIL module? Link

You can try to reinstall it on your computer.

Functional programming is "programming with functions," where a function has some expected mathematical properties, including referential transparency. From these properties, further properties flow, in particular familiar reasoning steps enabled by substitutability that lead to mathematical proofs (i.e. justifying confidence in a result).

It follows that a functional program is merely an expression.

You can easily see the contrast between the two styles by noting the places in an imperative program where an expression is no longer referentially transparent (and therefore is not built with functions and values, and cannot itself be part of a function). The two most obvious places are: mutation (e.g. variables) other side-effects non-local control flow (e.g. exceptions)

On this framework of programs-as-expressions which are composed of functions and values, is built an entire practical paradigm of languages, concepts, "functional patterns", combinators, and various type systems and evaluation algorithms.

By the most extreme definition, almost any language—even C or Java—can be called functional, but usually people reserve the term for languages with specifically relevant abstractions (such as closures, immutable values, and syntactic aids like pattern matching). As far as use of functional programming is concerned it involves use of functins and builds code without any side effects . used to write proofs

In addition to great extension written here if you are lazy to find and replace old NSLocalizedString you can open find & replace in Xcode and in the find section you can write NSLocalizedString\(\(".*"\), comment: ""\) then in the replace section you need to write $1.localized to change all NSLocalizedString with "blabla".localized in your project.

Use Connection.isClosed() function.

The JavaDoc states:

Retrieves whether this Connection object has been closed. A connection is closed if the method close has been called on it or if certain fatal errors have occurred. This method is guaranteed to return true only when it is called after the method Connection.close has been called.

Just to add something to what @Fionnuala Said, The below functions can be used. These even work for leap years.

'If you pass #2016/20/01# you get #2016/31/01#
Public Function GetLastDate(tempDate As Date) As Date
    GetLastDate = DateSerial(Year(tempDate), Month(tempDate) + 1, 0)
End Function

'If you pass #2016/20/01# you get 31
Public Function GetLastDay(tempDate As Date) As Integer
    GetLastDay = Day(DateSerial(Year(tempDate), Month(tempDate) + 1, 0))
End Function

Thankfully(?), in SQL Server 2012+, you can now use FORMAT() to achieve this:

FORMAT(@s,'#,0.0000')

[Query]:

declare @s decimal(18,10);
set @s = 1234.1234567;
select replace(convert(varchar,cast(floor(@s) as money),1),'.00',
    '.'+right(cast(@s * 10000 +10000.5 as int),4))

In the first part, we use MONEY->VARCHAR to produce the commas, but FLOOR() is used to ensure the decimals go to .00. This is easily identifiable and replaced with the 4 digits after the decimal place using a mixture of shifting (*10000) and CAST as INT (truncation) to derive the digits.

[Results]:

|   COLUMN_0 |
--------------
| 1,234.1235 |

But unless you have to deliver business reports using SQL Server Management Studio or SQLCMD, this is NEVER the correct solution, even if it can be done. Any front-end or reporting environment has proper functions to handle display formatting.

In my case in ASP MVC it was a method in controller that was returning null to View because of a wrong if statement.

if (condition)
{
    return null;
}

Condition fixed and I returned View, Problem fixed. There was nothing with encoding but I don't know why that was my error.

return View(result); // result is View's model

That name looks derived from an object URL GUID. Do the following to get the object URL that the name was derived from.

var URL = self.URL || self.webkitURL || self;
var object_url = URL.createObjectURL(blob);
URL.revokeObjectURL(object_url);

object_url will be formatted as blob:{origin}{GUID} in Google Chrome and moz-filedata:{GUID} in Firefox. An origin is the protocol+host+non-standard port for the protocol. For example, blob:http://stackoverflow.com/e7bc644d-d174-4d5e-b85d-beeb89c17743 or blob:http://[::1]:123/15111656-e46c-411d-a697-a09d23ec9a99. You probably want to extract the GUID and strip any dashes.

1. open cmd

   • type in netstat -a -n -o

   • find TCP [the IP address]:[port number] .... #[target_PID]# (ditto for UDP)

   • (Btw, kill [target_PID] didn't work for me)

2. CTRL+ALT+DELETE and choose "start task manager"

   • Click on "Processes" tab

   • Enable "PID" column by going to: View > Select Columns > Check the box for PID

   • Find the PID of interest and "END PROCESS"

3. Now you can rerun the server on [the IP address]:[port number] without a problem

It depends on the kind of test double you want to interact with:

• If you don't use doNothing and you spy an object, the real method is called

In other words, with mocking the only useful interactions with a collaborator are the ones that you provide. By default functions will return null, void methods do nothing.

Had the same error but with a different scenario. I had my state as

        this.state = {
        date: new Date()
    }

so when I was asking it in my Class Component I had

p>Date = {this.state.date}</p>

Instead of

p>Date = {this.state.date.toLocaleDateString()}</p>

you are trying to open a socket to a file on the remote host which is not correct. you could make a socket connection (TCP/UDP) to a port number on a remote host. so your code should be like this:

fsockopen('www.mysite.com', 80);

if you are trying to create a file pointer resource to a remote file, you may use the fopen() function. but to do this, you need to specify the application protocol as well.

PHP provides default stream wrappers for URL file opens. based on the schema of the URL the appropriate stream wrapper will be called internally. the URL you are trying to open does not have a valid schema for this solution. make sure there is a schema like "http://" or "ftp://" in it.

so the code would be like this:

$fp = fopen('http://www.mysite.com/path/file.txt');

Besides I don't think the HTTP stream wrapper (that handles actions on file resources on URLs with http schema) supports writing of data. you can use fread() to read contents of a the URL through HTTP, but I'm not sure about writing.

EDIT: from comments and other answers I figured out you would want to send a HTTP request to the specified URL. the methods described in this answer are for when you want to receive data from the remote URL. if you want to send data, you can use http_request() to do this.

Although this topic has already been answered there's more to say.

First of all: Clearly we need some definitions here. The InetAddress.getLocalHost().getHostName() gives you the name of the host as seen from a network perspective. The problems with this approach are well documented in the other answers: it often requires a DNS lookup, it's ambiguous if the host has multiple network interfaces and it just plain fails sometimes (see below).

But on any OS there's another name as well. A name of the host that gets defined very early in the boot process, long before the network is initialized. Windows refers to this as computername, Linux calls it kernel hostname and Solaris uses the word nodename. I like best the word computername, so I'll use that word from now on.

Finding the computername

• On Linux/Unix the computername is what you get from the C function gethostname(), or hostname command from shell or HOSTNAME environment variable in Bash-like shells.

• On Windows the computername is what you get from environment variable COMPUTERNAME or Win32 GetComputerName function.

Java has no way of obtaining what I've defined as 'computername'. Sure, there are workarounds as described in other answers, like for Windows calling System.getenv("COMPUTERNAME"), but on Unix/Linux there's no good workaround without resorting to JNI/JNA or Runtime.exec(). If you don't mind a JNI/JNA solution then there's gethostname4j which is dead simple and very easy to use.

Let's move on with two examples, one from Linux and one from Solaris, which demonstrate how you can easily get into a situation where you cannot obtain the computername using standard Java methods.

Linux example

On a newly created system, where the host during installation has been named as 'chicago', we now change the so-called kernel hostname:

$ hostnamectl --static set-hostname dallas

Now the kernel hostname is 'dallas', as evident from the hostname command:

$ hostname
dallas

But we still have

$ cat /etc/hosts
127.0.0.1   localhost
127.0.0.1   chicago

There's no misconfiguration in this. It just means the host's networked name (or rather the name of the loopback interface) is different from the host's computername.

Now, try executing InetAddress.getLocalHost().getHostName() and it will throw java.net.UnknownHostException. You are basically stuck. There's no way to retrieve neither the value 'dallas' nor the value 'chicago'.

Solaris example

The example below is based on Solaris 11.3.

The host has deliberately been configured so that the loopback name <> nodename.

In other words we have:

$ svccfg -s system/identity:node listprop config
...
...
config/loopback             astring        chicago
config/nodename             astring        dallas

and the contents of /etc/hosts :

:1 chicago localhost
127.0.0.1 chicago localhost loghost

and the result of the hostname command would be:

$ hostname
dallas

Just like in the Linux example a call to InetAddress.getLocalHost().getHostName() will fail with

java.net.UnknownHostException: dallas:  dallas: node name or service name not known

Just like the Linux example you are now stuck. There's no way to retrieve neither the value 'dallas' nor the value 'chicago'.

When will you really struggle with this?

Very often you'll find that InetAddress.getLocalHost().getHostName() will indeed return a value which is equal to the computername. So there's no problem (except for the added overhead of name resolution).

The problem arises typically within PaaS environments where there's a difference between computername and the name of the loopback interface. For example people report problems in Amazon EC2.

Bug/RFE reports

A bit of searching reveals this RFE report : link1, link2. However, judging from the comments on that report the issue seems to have been largely misunderstood by the JDK team, so it is unlikely it will be addressed.

I like the comparison in the RFE to other programming languages.

Already some great answers to this question, however here is a nice snippet that I use regularly to drop rows if they have non-numeric values on some columns:

# Eliminate invalid data from dataframe (see Example below for more context)

num_df = (df.drop(data_columns, axis=1)
         .join(df[data_columns].apply(pd.to_numeric, errors='coerce')))

num_df = num_df[num_df[data_columns].notnull().all(axis=1)]

The way this works is we first drop all the data_columns from the df, and then use a join to put them back in after passing them through pd.to_numeric (with option 'coerce', such that all non-numeric entries are converted to NaN). The result is saved to num_df.

On the second line we use a filter that keeps only rows where all values are not null.

Note that pd.to_numeric is coercing to NaN everything that cannot be converted to a numeric value, so strings that represent numeric values will not be removed. For example '1.25' will be recognized as the numeric value 1.25.

Disclaimer: pd.to_numeric was introduced in pandas version 0.17.0

Example:

In [1]: import pandas as pd

In [2]: df = pd.DataFrame({"item": ["a", "b", "c", "d", "e"],
   ...:                    "a": [1,2,3,"bad",5],
   ...:                    "b":[0.1,0.2,0.3,0.4,0.5]})

In [3]: df
Out[3]: 
     a    b item
0    1  0.1    a
1    2  0.2    b
2    3  0.3    c
3  bad  0.4    d
4    5  0.5    e

In [4]: data_columns = ['a', 'b']

In [5]: num_df = (df
   ...:           .drop(data_columns, axis=1)
   ...:           .join(df[data_columns].apply(pd.to_numeric, errors='coerce')))

In [6]: num_df
Out[6]: 
  item   a    b
0    a   1  0.1
1    b   2  0.2
2    c   3  0.3
3    d NaN  0.4
4    e   5  0.5

In [7]: num_df[num_df[data_columns].notnull().all(axis=1)]
Out[7]: 
  item  a    b
0    a  1  0.1
1    b  2  0.2
2    c  3  0.3
4    e  5  0.5

I think the question was about to open a local file directly instead of downloading a local file to the download folder and open the file in the download folder, which seems not possible in Chrome, except some add-on mentioned above.

My workaround would be to right click -> Copy the link location Windows + R and paste the link there and Enter It will go to the file directly.

In order to create a file in the remote machine with the ad-hoc command

ansible client -m file -a"dest=/tmp/file state=touch"

Please correct me if I am wrong

what @yabin ya says is a cool solution, just remind you that: if u still get the same problem,go to Settings-Version Control-GitHub and uncheck the Clone git repositories using ssh.

If you are willing to part with some money, JNIWrapper is a useful library with a Winpack, you will be able to get file system events on certain files. Unfortunately windows only.

See https://www.teamdev.com/jniwrapper.

Otherwise, resorting to native code is not always a bad thing especially when the best on offer is a polling mechanism as against a native event.

I've noticed that Java file system operations can be slow on some computers and can easily affect the application's performance if not handled well.

(current / maximum) * 100. In your case, (2 / 10) * 100.

A quick answer, that doesn't require you to edit any configuration files (and works on other operating systems as well as Windows), is to just find the directory that you are allowed to save to using:

mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-----------------------+
| Variable_name    | Value                 |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.06 sec)

And then make sure you use that directory in your SELECT statement's INTO OUTFILE clause:

SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE '/var/lib/mysql-files/report.csv'
    FIELDS TERMINATED BY '#'
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'

Original answer

I've had the same problem since upgrading from MySQL 5.6.25 to 5.6.26.

In my case (on Windows), looking at the MySQL56 Windows service shows me that the options/settings file that is being used when the service starts is C:\ProgramData\MySQL\MySQL Server 5.6\my.ini

On linux the two most common locations are /etc/my.cnf or /etc/mysql/my.cnf.

Opening this file I can see that the secure-file-priv option has been added under the [mysqld] group in this new version of MySQL Server with a default value:

secure-file-priv="C:/ProgramData/MySQL/MySQL Server 5.6/Uploads"

You could comment this (if you're in a non-production environment), or experiment with changing the setting (recently I had to set secure-file-priv = "" in order to disable the default). Don't forget to restart the service after making changes.

Alternatively, you could try saving your output into the permitted folder (the location may vary depending on your installation):

SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/report.csv'
    FIELDS TERMINATED BY '#'
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'

It's more common to have comma seperate values using FIELDS TERMINATED BY ','. See below for an example (also showing a Linux path):

SELECT *
FROM table
INTO OUTFILE '/var/lib/mysql-files/report.csv'
    FIELDS TERMINATED BY ',' ENCLOSED BY '"'
    ESCAPED BY ''
    LINES TERMINATED BY '\n';

In Controller i have specified the below code with ActionResult which is a base class that can have 11 subtypes in MVC like: ViewResult, PartialViewResult, EmptyResult, RedirectResult, RedirectToRouteResult, JsonResult, JavaScriptResult, ContentResult, FileContentResult, FileStreamResult, FilePathResult.

    public ActionResult Index()
                {
                    if (HttpContext.Session["LoggedInUser"] == null)
                    {
                        return RedirectToAction("Login", "Home");
                    }

                    else
                    {
                        return View(); // returns ViewResult
                    }

                }
//More Examples

    [HttpPost]
    public ActionResult Index(string Name)
    {
     ViewBag.Message = "Hello";
     return Redirect("Account/Login"); //returns RedirectResult
    }

    [HttpPost]
    public ActionResult Index(string Name)
    {
    return RedirectToRoute("RouteName"); // returns RedirectToRouteResult
    }

Likewise we can return all these 11 subtypes by using ActionResult() without specifying every subtype method explicitly. ActionResult is the best thing if you are returning different types of views.

Had this issue with spring-boot 2.4.1 when running the tests in bulk from [Intellij Idea] version 2020.3. The issue doesn't appear when running only one test at a time from IntelliJ or when running the tests from command line.

Maybe Intellij caching problem?

Follow up:

The problem appears when running tests using the maven-surefire-plugin reuseForks true. Using reuseForks false would provide a quick fix, but the tests running time will increase dramatically. Because we are reusing forks, the database context might become dirty due to other tests that are run - without cleaning the database context afterwards. The obvious solution would be to clean the database context before running a test, but the best one should be to clean up the database context after each test (solving the root cause of the original problem). Using the @Transactional annotation on your test methods will guarantee that your database changes are rolled back at the end of the test methods. See the Spring documentation on transactions: https://docs.spring.io/spring-framework/docs/current/reference/html/testing.html#testcontext-tx.

I think someone should face the same problem that can't find out the branch, although it actually exists in one branch.

You'd better pull all first:

git pull --all

Then do the branch search:

git name-rev <SHA>

or:

git branch --contains <SHA>

Ok, it seems that some versions of PHP have a limitation of length of GET params:

Please note that PHP setups with the suhosin patch installed will have a default limit of 512 characters for get parameters. Although bad practice, most browsers (including IE) supports URLs up to around 2000 characters, while Apache has a default of 8000.

To add support for long parameters with suhosin, add suhosin.get.max_value_length = <limit> in php.ini

[Offering a somewhat more descriptive answer than the answer provided by @Ajni.]

This can also be achieved using LINQ fluent syntax:

var list = ctn.Items
    .Where(t=> t.DeliverySelection == true && t.Delivery.SentForDelivery == null)
    .OrderBy(t => t.Delivery.SubmissionDate)
    .Take(5);

Note that each method (Where, OrderBy, Take) that appears in this LINQ statement takes a lambda expression as an argument. Also note that the documentation for Enumerable.Take begins with:

Returns a specified number of contiguous elements from the start of a sequence.

In short, yes. But there are times when you might favor one vs. the other. Google "case switch vs. if else". There are some discussions already on SO too. Also, here is a good video that talks about it in the context of MATLAB:

http://blogs.mathworks.com/pick/2008/01/02/matlab-basics-switch-case-vs-if-elseif/

Personally, when I have 3 or more cases, I usually just go with case/switch.

It is really simple, there are just some syntax you have to keep in mind.

Arrays.sort(contests, (a, b) -> Integer.compare(a[0],b[0]));//increasing order ---1

Arrays.sort(contests, (b, a) -> Integer.compare(b[0],a[0]));//increasing order ---2

Arrays.sort(contests, (a, b) -> Integer.compare(b[0],a[0]));//decreasing order ---3

Arrays.sort(contests, (b, a) -> Integer.compare(a[0],b[0]));//decreasing order ---4

If you notice carefully, then it's the change in the order of 'a' and 'b' that affects the result. For line 1, the set is of (a,b) and Integer.compare(a[0],b[0]), so it is increasing order. Now if we change the order of a and b in any one of them, suppose the set of (a,b) and Integer.compare(b[0],a[0]) as in line 3, we get decreasing order.

I found a article about Logical vs Physical Address in Operating System, which clearly explains about this.

Logical Address is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically therefore it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a programs perspective. The hardware device called Memory-Management Unit is used for mapping logical address to its corresponding physical address.

Physical Address identifies a physical location of required data in a memory. The user never directly deals with the physical address but can access by its corresponding logical address. The user program generates the logical address and thinks that the program is running in this logical address but the program needs physical memory for its execution therefore the logical address must be mapped to the physical address bu MMU before they are used. The term Physical Address Space is used for all physical addresses corresponding to the logical addresses in a Logical address space.

Simply call getUrl() on URLConnection instance after calling getInputStream():

URLConnection con = new URL( url ).openConnection();
System.out.println( "orignal url: " + con.getURL() );
con.connect();
System.out.println( "connected url: " + con.getURL() );
InputStream is = con.getInputStream();
System.out.println( "redirected url: " + con.getURL() );
is.close();

If you need to know whether the redirection happened before actually getting it's contents, here is the sample code:

HttpURLConnection con = (HttpURLConnection)(new URL( url ).openConnection());
con.setInstanceFollowRedirects( false );
con.connect();
int responseCode = con.getResponseCode();
System.out.println( responseCode );
String location = con.getHeaderField( "Location" );
System.out.println( location );

I had this issue while testing software. Drivers were not signed.

Tip for me was: in cmd line: (administrator) bcdedit /set TESTSIGNING ON and reboot the machine (shutdown -r -t 5)

Use Activity.getWindow() to get the window of your activity; use Window.addFlags() to add whichever of the following flags in WindowManager.LayoutParams that you desire:

• FLAG_DISMISS_KEYGUARD

• FLAG_SHOW_WHEN_LOCKED

• FLAG_TURN_SCREEN_ON

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:

SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;

For those who uses an opener, you can achieve the same thing based on Enno Gröper's great answer:

import urllib2, ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

opener = urllib2.build_opener(urllib2.HTTPSHandler(context=ctx), your_first_handler, your_second_handler[...])
opener.addheaders = [('Referer', 'http://example.org/blah.html')]

content = opener.open("https://localhost/").read()

And then use it as before.

According to build_opener and HTTPSHandler, a HTTPSHandler is added if ssl module exists, here we just specify our own instead of the default one.

You've already got it: A if test else B is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:

{ (some_key if condition else default_key):(something_if_true if condition
          else something_if_false) for key, value in dict_.items() }

The final if clause acts as a filter, which is different from having the conditional expression.

At first I thought the Paste Special was the holy grail! But then I tried it and my hair turned white just like the Indiana Jones movie.

But now I use http://xmltocsharp.azurewebsites.net/ and now I'm as young as ever.

Here's a segment of what it generated:

namespace Xml2CSharp
{
    [XmlRoot(ElementName="entry")]
    public class Entry {
        [XmlElement(ElementName="hybrisEntryID")]
        public string HybrisEntryID { get; set; }
        [XmlElement(ElementName="mapicsLineSequenceNumber")]
        public string MapicsLineSequenceNumber { get; set; }

Well, to do this one can also use the freopen function provided in C++ - http://www.cplusplus.com/reference/cstdio/freopen/ and read the file line by line as follows -:

#include<cstdio>
#include<iostream>

using namespace std;

int main(){
   freopen("path to file", "rb", stdin);
   string line;
   while(getline(cin, line))
       cout << line << endl;
   return 0;
}

My understanding after reading the link offered by G.Grothendieck is that %>% is an operator that pipes functions. This helps readability and productivity as it's easier to follow the flow of multiple functions through these pipes than going backwards when multiple function are nested.

Docker requires your command to keep running in the foreground. Otherwise, it thinks that your applications stops and shutdown the container.

So if your docker entry script is a background process like following:

/usr/local/bin/confd -interval=30 -backend etcd -node $CONFIG_CENTER &

The '&' makes the container stop and exit if there are no other foreground process triggered later. So the solution is just remove the '&' or have another foreground CMD running after it, such as

tail -f server.log

Session["YourItem"] = "";

Works great in .net razor web pages.

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

Your problem is in this line: Message messageObject = new Message ();

If you are able to use the bash shell, you can consider simply running the R code from within a bash script and piping the stdout and stderr streams to a file. Here is an example using a heredoc:

File: test.sh

#!/bin/bash
# this is a bash script
echo "Hello World, this is bash"

test1=$(echo "This is a test")

echo "Here is some R code:"

Rscript --slave --no-save --no-restore - "$test1" <<EOF
  ## R code
  cat("\nHello World, this is R\n")
  args <- commandArgs(TRUE)
  bash_message<-args[1]
  cat("\nThis is a message from bash:\n")
  cat("\n",paste0(bash_message),"\n")
EOF

# end of script 

Then when you run the script with both stderr and stdout piped to a log file:

$ chmod +x test.sh
$ ./test.sh
$ ./test.sh &>test.log
$ cat test.log
Hello World, this is bash
Here is some R code:

Hello World, this is R

This is a message from bash:

 This is a test

Other things to look at for this would be to try simply pipping the stdout and stderr right from the R heredoc into a log file; I haven't tried this yet but it will probably work too.

I'll assume you need it for one-off things. I'll assume you're a PC developer.

Use the Stack, Luke. Use it everywhere. Don't use malloc / free for small allocations, ever.

#include <string.h>
#include <stdio.h>

#define STR_SIZE 10000

int main()
{
  char s1[] = "oppa";
  char s2[] = "gangnam";
  char s3[] = "style";

  {
    char result[STR_SIZE] = {0};
    snprintf(result, sizeof(result), "%s %s %s", s1, s2, s3);
    printf("%s\n", result);
  }
}

If 10 KB per string won't be enough, add a zero to the size and don't bother, - they'll release their stack memory at the end of the scopes anyway.

You should start by defining what a tree is (for the domain), this is best done by defining the interface first. Not all trees structures are modifyable, being able to add and remove nodes should be an optional feature, so we make an extra interface for that.

There's no need to create node objects which hold the values, in fact I see this as a major design flaw and overhead in most tree implementations. If you look at Swing, the TreeModel is free of node classes (only DefaultTreeModel makes use of TreeNode), as they are not really needed.

public interface Tree <N extends Serializable> extends Serializable {
    List<N> getRoots ();
    N getParent (N node);
    List<N> getChildren (N node);
}

Mutable tree structure (allows to add and remove nodes):

public interface MutableTree <N extends Serializable> extends Tree<N> {
    boolean add (N parent, N node);
    boolean remove (N node, boolean cascade);
}

Given these interfaces, code that uses trees doesn't have to care much about how the tree is implemented. This allows you to use generic implementations as well as specialized ones, where you realize the tree by delegating functions to another API.

Example: file tree structure

public class FileTree implements Tree<File> {

    @Override
    public List<File> getRoots() {
        return Arrays.stream(File.listRoots()).collect(Collectors.toList());
    }

    @Override
    public File getParent(File node) {
        return node.getParentFile();
    }

    @Override
    public List<File> getChildren(File node) {
        if (node.isDirectory()) {
            File[] children = node.listFiles();
            if (children != null) {
                return Arrays.stream(children).collect(Collectors.toList());
            }
        }
        return Collections.emptyList();
    }
}

Example: generic tree structure (based on parent/child relations):

public class MappedTreeStructure<N extends Serializable> implements MutableTree<N> {

    public static void main(String[] args) {

        MutableTree<String> tree = new MappedTreeStructure<>();
        tree.add("A", "B");
        tree.add("A", "C");
        tree.add("C", "D");
        tree.add("E", "A");
        System.out.println(tree);
    }

    private final Map<N, N> nodeParent = new HashMap<>();
    private final LinkedHashSet<N> nodeList = new LinkedHashSet<>();

    private void checkNotNull(N node, String parameterName) {
        if (node == null)
            throw new IllegalArgumentException(parameterName + " must not be null");
    }

    @Override
    public boolean add(N parent, N node) {
        checkNotNull(parent, "parent");
        checkNotNull(node, "node");

        // check for cycles
        N current = parent;
        do {
            if (node.equals(current)) {
                throw new IllegalArgumentException(" node must not be the same or an ancestor of the parent");
            }
        } while ((current = getParent(current)) != null);

        boolean added = nodeList.add(node);
        nodeList.add(parent);
        nodeParent.put(node, parent);
        return added;
    }

    @Override
    public boolean remove(N node, boolean cascade) {
        checkNotNull(node, "node");

        if (!nodeList.contains(node)) {
            return false;
        }
        if (cascade) {
            for (N child : getChildren(node)) {
                remove(child, true);
            }
        } else {
            for (N child : getChildren(node)) {
                nodeParent.remove(child);
            }
        }
        nodeList.remove(node);
        return true;
    }

    @Override
    public List<N> getRoots() {
        return getChildren(null);
    }

    @Override
    public N getParent(N node) {
        checkNotNull(node, "node");
        return nodeParent.get(node);
    }

    @Override
    public List<N> getChildren(N node) {
        List<N> children = new LinkedList<>();
        for (N n : nodeList) {
            N parent = nodeParent.get(n);
            if (node == null && parent == null) {
                children.add(n);
            } else if (node != null && parent != null && parent.equals(node)) {
                children.add(n);
            }
        }
        return children;
    }

    @Override
    public String toString() {
        StringBuilder builder = new StringBuilder();
        dumpNodeStructure(builder, null, "- ");
        return builder.toString();
    }

    private void dumpNodeStructure(StringBuilder builder, N node, String prefix) {
        if (node != null) {
            builder.append(prefix);
            builder.append(node.toString());
            builder.append('\n');
            prefix = "  " + prefix;
        }
        for (N child : getChildren(node)) {
            dumpNodeStructure(builder, child, prefix);
        }
    }
}

Similar to Ryan Rodemoyer's answer, I found that when the UriTemplate on the Contract is not valid you can get this error. In my case, I was using the same parameter twice. For example:

/Root/{Name}/{Name}

For those who might be trying to create a Travis Build, the default path from which Django is installed from the requirements.txt file points to a repo whose django_extensions module has not been updated. The only workaround, for now, is to install from the master branch using pip. That is where the patch is made. But for now, we'll have to wait.

You can try this in the meantime, it might help

- pip install git+https://github.com/chibisov/drf-extensions.git@master

- pip install git+https://github.com/django-extensions/django-extensions.git@master

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.

[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path');

http.createServer(function(request, response) {
    var filePath = path.join(__dirname, 'myfile.mp3');
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to readStream.pipe()
    readStream.pipe(response);
})
.listen(2000);

There is no real "difference". Web site is a more anachronistic term that exists from the early days of the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites). Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.

If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels more like an application as a web app.

The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.

Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.

i know i'm late but this might help. you can add specific type of image or other file type and do validation in your code :

<input style="margin-left: 10px; margin-top: 5px;" type="file" accept="image/x-png,image/jpeg,application/pdf" (change)="handleFileInput($event,'creditRatingFile')" name="creditRatingFile" id="creditRatingFile">

      handleFileInput(event) {
    console.log(event);
    const file = event.target.files[0];
    if (file.size > 2097152) {
        throw err;
    } else if (
      file.type !== "application/pdf"  &&
      file.type !== "application/wps-office.pdf"   && 
      file.type !== 'application/pdf'  && file.type !== 'image/jpg'  && file.type !== 'image/jpeg'  && file.type !== "image/png"
    ) {
throw err;
    } else {
      
        console.log('file valid')
    }
  }

I think you're confused because you haven't declared a TimeSpan you've declared a TimeSpan? which is a nullable TimeSpan. Either remove the question mark if you don't need it to be nullable or use variable.Value.TotalHours.

Simply mark any method you need to fake as virtual (and not private). Then you will be able to create a fake that can override the method.

If you use new Mock<Type> and you don't have a parameterless constructor then you can pass the parameters as the arguments of the above call as it takes a type of param Objects

I had that problem, and I try ti fix with this:

rm -f .git/index
git reset

BUT it did not work. The solution? For some reason I had others .git folders in sub directories. I delete those .git folders (not the principal) and git reset again. Once they were deleted, everything worked again.

Solution

1. Download log4j.jar file
2. Add the log4j.jar file to build path

3. Call logger by:

   private static org.apache.log4j.Logger log 
       = Logger.getLogger(<class-where-this-is-used>.class);
   

4. if log4j properties does not exist, create new file log4j.properties file new file in bin directory:

   /workspace/projectdirectory/bin/
   

Sample log4j.properties file

log4j.rootLogger=debug, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%t %-5p %c{2} - %m%n 

If you are inserting one record into your table, you can do

INSERT INTO yourTable 
VALUES(value1, value2)

But since you want to insert more than one record, you can use a SELECT FROM in your SQL statement.

so you will want to do this:

INSERT INTO prices (group, id, price) 
SELECT 7, articleId, 1.50
from article 
WHERE name LIKE 'ABC%'

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

If you change a little the question to ask about 2 assembly registers instead of variables, you can use also the xchg operation as one option, and the stack operation as another one.

If you check your CSS coding with W3C validator, you will see if your CSS code is acceptable, even if it worked in the major browsers.

Creating a transparent border via CSS, as written above,

border: 1px solid rgba(255, 0, 0, .5);

is not accepted by W3C standards, not even for CSS3. I used the direct input validator with the following CSS code,

.test { border: 1px solid rgba(255, 0, 0, .5); }

The results were,

Value Error : border Too many values or values are not recognized : 1px solid rgba(255,0,0,0.5 )

Unfortunate that the alpha value (the letter "a" at the end of "rgb") is not accepted by W3C as part of the border color values as yet. I do wonder why it is not standardized, since it works in all browsers. The only hitch is whether you want to stick to W3C standards or step aside from it to create something in CSS.

To use W3C online CSS validator / Direct Input.

Always a good idea to use a validator to check your work, it really helps finding small or even large errors in coding when your going cross-eyed after hours of coding work.

I had a similar problem and solved it using list...not sure if this will help or not

classes = list(unique_labels(y_true, y_pred))

<stdarg.h> allows you to define variadic functions (which accept an indefinite number of arguments, like printf()). I would define a function which took an arbitrary number of pairs of arguments, one which specifies the property to be updated, and one which specifies the value. Use an enum or a string to specify the name of the property.

Try :

List<string> MyList = new List<string>();
MyList.Add("HELLO");
MyList.Add("WORLD");

listBox1.DataSource = MyList;

Have a look at ListControl.DataSource Property

I'd recommend application/octet-stream as RFC2046 says "The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data" and "The recommended action for an implementation that receives an "application/octet-stream" entity is to simply offer to put the data in a file[...]".

I think that way you will get better handling from arbitrary programs, that might barf when encountering your unknown mime type.

df = df_try
for i in range(4):
   df = df.append(df_try)

# Here, we have df_try times 5

df = df.append(df)

# Here, we have df_try times 10

From the asar documentation

(the use of npx here is to avoid to install the asar tool globally with npm install -g asar)

Extract the whole archive:

npx asar extract app.asar destfolder 

Extract a particular file:

npx asar extract-file app.asar main.js

A class is basically a definition, and contains the object's code. An object is an instance of a class

for example if you say

String word = new String();

the class is the String class, which describes the object (instance) word.

When a class is declared, no memory is allocated so class is just a template.

When the object of the class is declared, memory is allocated.

create a full-width View with alignItems: "center" then insert desired children inside.

import React from "react";
import {View} from "react-native";

export default class AbsoluteComponent extends React.Component {
  render(){
    return(
     <View style={{position: "absolute", left: 0, right: 0, alignItems: "center"}}>
      {this.props.children}
     </View>    
    )
  }
}

you can add properties like bottom: 30 for bottom aligned component.

For most controls, you set its height and width to Auto in the XAML, and it will size to fit its content.

In code, you set the width/height to double.NaN. For details, see FrameworkElement.Width, particularly the "remarks" section.

For OSX I recommend: jarzilla or JD-GUI

They both allow you to view jar,war,etc. file content and decompiles any class files inside of them.

Jarzilla: https://code.google.com/p/jarzilla/
JD-GUI: http://jd.benow.ca/

For Java, from a command line:

java -version

will indicate whether it's 64-bit or not.

Output from the console on my Ubuntu box:

java version "1.6.0_12-ea"
Java(TM) SE Runtime Environment (build 1.6.0_12-ea-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.2-b01, mixed mode)

IE will indicate 64-bit versions in the About dialog, I believe.

Generally there are two ways to do it, a converter class or a property in the Viewmodel that essentially converts the value for you.

I tend to use the property approach if it is a one off conversion. If you want to reuse it, use the converter. Below, find an example of the converter:

<ValueConversion(GetType(Boolean), GetType(Visibility))> _
Public Class BoolToVisibilityConverter
    Implements IValueConverter

    Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert

        If value IsNot Nothing Then
            If value = True Then 
                Return Visibility.Visible
            Else
                Return Visibility.Collapsed
            End If
        Else
            Return Visibility.Collapsed
        End If
    End Function

    Public Function ConvertBack(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
        Throw New NotImplementedException
    End Function
End Class

A ViewModel property method would just check the boolean property value, and return a visibility based on that. Be sure to implement INotifyPropertyChanged and call it on both the Boolean and Visibility properties to updated properly.

I used DecimalFormat for formatting the BigDecimal instead of formatting the String, seems no problems with it.

The code is something like this:

bd = bd.setScale(2, BigDecimal.ROUND_DOWN);

DecimalFormat df = new DecimalFormat();

df.setMaximumFractionDigits(2);

df.setMinimumFractionDigits(0);

df.setGroupingUsed(false);

String result = df.format(bd);

There's built-in solution for your problem: ModelChoiceField.

Generally, it's always worth trying to use ModelForm when you need to create/change database objects. Works in 95% of the cases and it's much cleaner than creating your own implementation.

Based on zainengineer's answer... Another approach is to make a deep copy of the object and strip circular references and stringify the result.

function cleanStringify(object) {_x000D_
    if (object && typeof object === 'object') {_x000D_
        object = copyWithoutCircularReferences([object], object);_x000D_
    }_x000D_
    return JSON.stringify(object);_x000D_
_x000D_
    function copyWithoutCircularReferences(references, object) {_x000D_
        var cleanObject = {};_x000D_
        Object.keys(object).forEach(function(key) {_x000D_
            var value = object[key];_x000D_
            if (value && typeof value === 'object') {_x000D_
                if (references.indexOf(value) < 0) {_x000D_
                    references.push(value);_x000D_
                    cleanObject[key] = copyWithoutCircularReferences(references, value);_x000D_
                    references.pop();_x000D_
                } else {_x000D_
                    cleanObject[key] = '###_Circular_###';_x000D_
                }_x000D_
            } else if (typeof value !== 'function') {_x000D_
                cleanObject[key] = value;_x000D_
            }_x000D_
        });_x000D_
        return cleanObject;_x000D_
    }_x000D_
}_x000D_
_x000D_

You can first convert your date strings with pandas.to_datetime, which gives you access to all of the numpy datetime and timedelta facilities. For example:

df['ArrivalDate'] = pandas.to_datetime(df['ArrivalDate'])
df['Month'] = df['ArrivalDate'].values.astype('datetime64[M]')

keep using the id

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class UserVerification extends Model
{
    protected $table = 'user_verification';
    protected $fillable =   [
                            'id',
                            'email',
                            'verification_token'
                            ];
    //$timestamps = false;
    protected $primaryKey = 'verification_token';
}

and get the email :

$usr = User::find($id);
$token = $usr->verification_token;
$email = UserVerification::find($token);

To add a class to a div that is generated via the HtmlGenericControl way you can use:

div1.Attributes.Add("class", "classname"); 

If you are using the Panel option, it would be:

panel1.CssClass = "classname";

You use Array.GetLength with the index of the dimension you wish to retrieve.

Alternatively to calling plt.show() at the end of the script, you can also control each figure separately doing:

f = plt.figure(1)
plt.hist........
............
f.show()

g = plt.figure(2)
plt.hist(........
................
g.show()

raw_input()

In this case you must call raw_input to keep the figures alive. This way you can select dynamically which figures you want to show

Note: raw_input() was renamed to input() in Python 3

You can use pad for this case:

ax.set_title("whatever", pad=20)

The error occurs because the object's ID is set. Hibernate distinguishes between transient and detached objects and persist works only with transient objects. If persist concludes the object is detached (which it will because the ID is set), it will return the "detached object passed to persist" error. You can find more details here and here.

However, this only applies if you have specified the primary key to be auto-generated: if the field is configured to always be set manually, then your code works.

You could simply use the unary + operator

(+new Date('2012.08.10')/1000).toFixed(0);

http://xkr.us/articles/javascript/unary-add/ - look under Dates.

I use a way that may look stupid but it works for me. I simply concat the columns I want to compare and use NOT IN:

SELECT *
FROM table1 t1
WHERE CONCAT(t1.first_name,t1.last_name) NOT IN (SELECT CONCAT(t2.first_name,t2.last_name) FROM table2 t2)

Sure you can:

Upcasting (using (Employee)someInstance) is generally easy as the compiler can tell you at compile time if a type is derived from another.

Downcasting however has to be done at run time generally as the compiler may not always know whether the instance in question is of the type given. C# provides two operators for this - is which tells you if the downcast works, and return true/false. And as which attempts to do the cast and returns the correct type if possible, or null if not.

To test if an employee is a manager:

Employee m = new Manager();
Employee e = new Employee();

if(m is Manager) Console.WriteLine("m is a manager");
if(e is Manager) Console.WriteLine("e is a manager");

You can also use this

Employee someEmployee = e  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (e) is a manager");

Employee someEmployee = m  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (m) is a manager");

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

The % operator in LIKE means "anything can be here".

Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.

But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)

Only Visual Studio 2015 Enterprise has code coverage built-in. See the feature matrix for details.

You can use the OpenCover.UI extension for code coverage check inside Visual Studio. It supports MSTest, nUnit, and xUnit.

The new version can be downloaded from here (release notes).

Stopwatch is fine, but loop the work 10^6 times, then divide by 10^6. You'll get a lot more precision.

Since these previous answers above, there is now a release of an Eclipse Plugin to assist with development using AngularJS:

https://marketplace.eclipse.org/content/angularjs-eclipse https://github.com/angelozerr/angularjs-eclipse/wiki/Installation---Update-Site (take a look around the other Wiki pages for information on features)

The release at the time of the answer is 0.1.0.

Please also checkout JSDT (http://www.eclipse.org/webtools/jsdt/) and also Eclipse VJET (http://eclipse.org/vjet/). The VJET project appears to be an attempt to provide better feature sets to the editor without being encumbered by the JSDT project (open source politics at play I guess).

Generic Collection classes cant be used with primitives. Use the Character and Integer wrapper classes instead.

Map<Character , Integer > checkSum = new HashMap<Character, Integer>();

Note that Details is a "View" page under the "Products" folder.

ProductId is the primary key of the table . Here is the line from Index.cshtml

 @Html.ActionLink("Details", "Details","Products" , new  {  id=item.ProductId  },null)

I'm not trying to provide a yet another alternative solution, but a "meta view" to this problem.

Answers already provided by Oded and Dimitre Novatchev are correct but what people really might mean with phrase "value is a number" is, how would I say it, open to interpretation.

In a way it all comes to this bizarre sounding question: "how do you want to express your numeric values?"

XPath function number() processes numbers that have

• possible leading or trailing whitespace
• preceding sign character only on negative values
• dot as an decimal separator (optional for integers)
• all other characters from range [0-9]

Note that this doesn't include expressions for numerical values that

• are expressed in exponential form (e.g. 12.3E45)
• may contain sign character for positive values
• have a distinction between positive and negative zero
• include value for positive or negative infinity

These are not just made up criteria. An element with content that is according to schema a valid xs:float value might contain any of the above mentioned characteristics. Yet number() would return value NaN.

So answer to your question "How i can check with XPath if a node value is number?" is either "Use already mentioned solutions using number()" or "with a single XPath 1.0 expression, you can't". Think about the possible number formats you might encounter, and if needed, write some kind of logic for validation/number parsing. Within XSLT processing, this can be done with few suitable extra templates, for example.

PS. If you only care about non-zero numbers, the shortest test is

<xsl:if test="number(myNode)">
    <!-- myNode is a non-zero number -->
</xsl:if>

don't put your commands in variables, just run it

You should use some HTML parsing library like lxml:

from lxml import etree
s = """<table>
  <tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
  <tr><td>a</td><td>b</td><td>c</td></tr>
  <tr><td>d</td><td>e</td><td>f</td></tr>
  <tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""
table = etree.HTML(s).find("body/table")
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
    values = [col.text for col in row]
    print dict(zip(headers, values))

prints

{'End Date': 'c', 'Start Date': 'b', 'Event': 'a'}
{'End Date': 'f', 'Start Date': 'e', 'Event': 'd'}
{'End Date': 'i', 'Start Date': 'h', 'Event': 'g'}

navigator.app.exitApp();

add this line where you want you exit the application.

I prefer

l.at(4)= -1;

while [4] is your index

For those of you running into the ever so common error "fatal: remote origin already exists.", or when trying to remove origin and you get "error: could not remove config section remote.origin", what you need to do is to set the origin manually.

Window's POSH~Git for Windows PowerShell (and GitHub for Windows' app) has a problem with this.

I ran into this, like I do so often, again when setting up my octopress. So, here's how I got it working.

First, check your remotes:

C:\gd\code\octopress [source +2 ~3 -0 !]> git remote -v
octopress       https://github.com/imathis/octopress.git (fetch)
octopress       https://github.com/imathis/octopress.git (push)
origin

You'll first note that my origin has no url. Any attempt to remove it, rename it, etc all fails.

So, change the url manually:

git remote set-url --add origin https://github.com/eduncan911/eduncan911.github.io.git

Then you can confirm it worked by running git remote -v again:

C:\gd\code\octopress [source +2 ~3 -0 !]> git remote -v
octopress       https://github.com/imathis/octopress.git (fetch)
octopress       https://github.com/imathis/octopress.git (push)
origin  https://github.com/eduncan911/eduncan911.github.io.git (fetch)
origin  https://github.com/eduncan911/eduncan911.github.io.git (push)

This has fixed dozens of git repos I've had issues with, GitHub, BitBucket GitLab, etc.

you also use this:

background-size:contain;
height: 0;
width: 100%;
padding-top: 66,64%; 

I don't know your div-values, but let's assume you've got those.

height: auto;
max-width: 600px;

Again, those are just random numbers. It could quite hard to make the background-image (if you would want to) with a fixed width for the div, so better use max-width. And actually it isn't complicated to fill a div with an background-image, just make sure you style the parent element the right way, so the image has a place it can go into.

Since this is about REST, just getting the request method from the server is not enough. You also need to receive RESTful route parameters. The reason for separating RESTful parameters and GET/POST/PUT parameters is that a resource needs to have its own unique URL for identification.

Here's one way of implementing RESTful routes in PHP using Slim:

https://github.com/codeguy/Slim

$app = new \Slim\Slim();
$app->get('/hello/:name', function ($name) {
  echo "Hello, $name";
});
$app->run();

And configure the server accordingly.

Here's another example using AltoRouter:

https://github.com/dannyvankooten/AltoRouter

$router = new AltoRouter();
$router->setBasePath('/AltoRouter'); // (optional) the subdir AltoRouter lives in

// mapping routes
$router->map('GET|POST','/', 'home#index', 'home');
$router->map('GET','/users', array('c' => 'UserController', 'a' => 'ListAction'));
$router->map('GET','/users/[i:id]', 'users#show', 'users_show');
$router->map('POST','/users/[i:id]/[delete|update:action]', 'usersController#doAction', 'users_do');

i tried all the solutions here and nothing worked in my C# .net 4.0 project. Hoping to help someone here the solution that worked for me:

As main class variables:

private static string appGuid = "WRITE AN UNIQUE GUID HERE";
private static Mutex mutex;

When you need to check if app is already running:

bool mutexCreated;
mutex = new Mutex(true, "Global\\" + appGuid, out mutexCreated);
if (mutexCreated)
    mutex.ReleaseMutex();

if (!mutexCreated)
{
    //App is already running, close this!
    Environment.Exit(0); //i used this because its a console app
}

I needed to close other istances only with some conditions, this worked well for my purpose

Closes should be done in reverse order of the opens.

If you use the Apache Commons Collections library in your project, you may use the CollectionUtils.isEmpty and MapUtils.isEmpty() methods which respectively check if a collection or a map is empty or null (i.e. they are "null-safe").

The code behind these methods is more or less what user @icza has written in his answer.

Regardless of what you do, remember that the less code you write, the less code you need to test as the complexity of your code decreases.

Or you can use std::advance

vector<int>::iterator i = L.begin();
advance(i, 2);

Can you try the following?

psexec \\server cmd /c "echo . | powershell script.ps1"

Hi I really hope this helps.

I tried all the options before and none really work on Windows. The only think that helped me accomplish this was trying to move the file. Event to the same place under an ATOMIC_MOVE. If the file is being written by another program or Java thread, this definitely will produce an Exception.

 try{

      Files.move(Paths.get(currentFile.getPath()), 
               Paths.get(currentFile.getPath()), StandardCopyOption.ATOMIC_MOVE);

      // DO YOUR STUFF HERE SINCE IT IS NOT BEING WRITTEN BY ANOTHER PROGRAM

 } catch (Exception e){

      // DO NOT WRITE THEN SINCE THE FILE IS BEING WRITTEN BY ANOTHER PROGRAM

 }

After testing all answers without success. Some times input take alpha character also.

Here is the last full working code with only numbers input also keeping in mind backspace button key event for user if something number is incorrect.

  k = event.which;_x000D_
  if ((k >= 96 && k <= 105) || k == 8) {_x000D_
    if ($(this).val().length == 10) {_x000D_
      if (k == 8) {_x000D_

"16:23:01" doesn't match the pattern of "hh:mm:ss tt" - it doesn't have an am/pm designator, and 16 clearly isn't in a 12-hour clock. You're specifying that format in the parsing part, so you need to match the format of the existing data. You want:

DateTime dateTime = DateTime.ParseExact(time, "HH:mm:ss",
                                        CultureInfo.InvariantCulture);

(Note the invariant culture, not the current culture - assuming your input genuinely always uses colons.)

If you want to format it to hh:mm:ss tt, then you need to put that part in the ToString call:

lblClock.Text = date.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);

Or better yet (IMO) use "whatever the long time pattern is for the culture":

lblClock.Text = date.ToString("T", CultureInfo.CurrentCulture);

Also note that hh is unusual; typically you don't want to 0-left-pad the number for numbers less than 10.

(Also consider using my Noda Time API, which has a LocalTime type - a more appropriate match for just a "time of day".)

As of CSS3, the spec has changed, allowing for only a single font-style. A comma-separated list (per CSS2) will be treated as if it were normal and override any earlier (default) entry. This will make fonts defined in this way appear italic permanently.

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: oblique;
}

In most cases, italic will probably be sufficient and oblique rules won't be necessary if you take care to define whichever you will use and stick to it.

I was having this problem when I creating a Edit View for my Model and I want to update just one field.

My solution for a simplest way is put the two field using :

 <%: Html.HiddenFor(model => model.ID) %>
 <%: Html.HiddenFor(model => model.Name)%>
 <%: Html.HiddenFor(model => model.Content)%>
 <%: Html.TextAreaFor(model => model.Comments)%>

Comments is the field that I only update in Edit View, that not have Required Attribute.

ASP.NET MVC 3 Entity

Use the raw_input() function to get input from users (2.x):

print "Enter a file name:",
filename = raw_input()

or just:

filename = raw_input('Enter a file name: ')

or if in Python 3.x:

filename = input('Enter a file name: ')

You can iterate through the <li>s in the <ul> and stop when you find the right one.

function getIndex(li) {
    var lis = li.parentNode.getElementsByTagName('li');
    for (var i = 0, len = lis.length; i < len; i++) {
        if (li === lis[i]) {
            return i;
        }
    }

}

Demo

Imagine you are designing a programming language. You decide that Strings are enclosed in quotes ("Apple"). Then you hit your first snag: how to represent quotation marks since you've already used them ? Just out of convention you decide to use \" to represent quotation marks. Then you have a second problem: how to represent \ ? Again, out of convention you decide to use \\ instead. Thankfully, the process ends there and this is sufficient. You can also use what is called an escape sequence to represent other characters such as the carriage return (\n).

If you have a gridview containing more than one checkbox .... you should try this ....

Object[] o=new Object[6];

for (int i = 0; i < dgverlist.RowCount; i++)
{
    for (int j = 2; j < dgverlist.ColumnCount; j++)
    {
        DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
        ch1 = (DataGridViewCheckBoxCell)dgverlist.Rows[i].Cells[j];

        if (ch1.Value != null)
        {
           o[i] = ch1.OwningColumn.HeaderText.ToString();

            MessageBox.Show(o[i].ToString());
        }
    }
}

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

 typeof(text) === 'string' || text instanceof String; 

you can use this, it will work for both case as

1. var text="foo"; // typeof will work

2. String text= new String("foo"); // instanceof will work
