I tried running on Windows, and got this problem after an update. I tried restarting the docker service as well as my pc, but nothing worked.

When running:

curl https://registry-1.docker.io/v2/ && echo Works

I got back:

{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":null}]}
Works

Eventually, I tried: https://github.com/moby/moby/issues/22635#issuecomment-284956961

By changing the fixed address to 8.8.8.8:

Which worked for me! I still got the unauthorized message for curl https://registry-1.docker.io/v2/ but I managed to pull images from docker hub.

1. First should understand the error meaning

Error not enough values to unpack (expected 3, got 2) means:

a 2 part tuple, but assign to 3 values

and I have written demo code to show for you:

#!/usr/bin/python
# -*- coding: utf-8 -*-
# Function: Showing how to understand ValueError 'not enough values to unpack (expected 3, got 2)'
# Author: Crifan Li
# Update: 20191212

def notEnoughUnpack():
    """Showing how to understand python error `not enough values to unpack (expected 3, got 2)`"""
    # a dict, which single key's value is two part tuple
    valueIsTwoPartTupleDict = {
        "name1": ("lastname1", "email1"),
        "name2": ("lastname2", "email2"),
    }

    # Test case 1: got value from key
    gotLastname, gotEmail = valueIsTwoPartTupleDict["name1"] # OK
    print("gotLastname=%s, gotEmail=%s" % (gotLastname, gotEmail))
    # gotLastname, gotEmail, gotOtherSomeValue = valueIsTwoPartTupleDict["name1"] # -> ValueError not enough values to unpack (expected 3, got 2)

    # Test case 2: got from dict.items()
    for eachKey, eachValues in valueIsTwoPartTupleDict.items():
        print("eachKey=%s, eachValues=%s" % (eachKey, eachValues))
    # same as following:
    # Background knowledge: each of dict.items() return (key, values)
    # here above eachValues is a tuple of two parts
    for eachKey, (eachValuePart1, eachValuePart2) in valueIsTwoPartTupleDict.items():
        print("eachKey=%s, eachValuePart1=%s, eachValuePart2=%s" % (eachKey, eachValuePart1, eachValuePart2))
    # but following:
    for eachKey, (eachValuePart1, eachValuePart2, eachValuePart3) in valueIsTwoPartTupleDict.items(): # will -> ValueError not enough values to unpack (expected 3, got 2)
        pass

if __name__ == "__main__":
    notEnoughUnpack()

using VSCode debug effect:

2. For your code

for name, email, lastname in unpaidMembers.items():

but error ValueError: not enough values to unpack (expected 3, got 2)

means each item(a tuple value) in unpaidMembers, only have 1 parts:email, which corresponding above code

    unpaidMembers[name] = email

so should change code to:

for name, email in unpaidMembers.items():

to avoid error.

But obviously you expect extra lastname, so should change your above code to

    unpaidMembers[name] = (email, lastname)

and better change to better syntax:

for name, (email, lastname) in unpaidMembers.items():

then everything is OK and clear.

Similar to Julien's answer above, I had success with the following:

fig, ax = plt.subplots(figsize=(10,4))
for key, grp in df.groupby(['ticker']):
    ax.plot(grp['Date'], grp['adj_close'], label=key)

ax.legend()
plt.show()

This solution might be more relevant if you want more control in matlab.

Solution inspired by: https://stackoverflow.com/a/52526454/10521959

[100 %]Solved. I had the same problem today. I checked my server space

df-h

I saw that server is out of space so i check which directory has most size by

sudo du -ch / | sort -h

I saw 12.2G /var/lib/jenkins so i entered this folder and cleared all the logs by

cd /var/libs/jenkins
rm *

and restart the jenkins it will work normal

sudo systemctl restart jenkins.service

Another option is CSVLogger: https://keras.io/callbacks/#csvlogger. It creates a csv file appending the result of each epoch. Even if you interrupt training, you get to see how it evolved.

Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq

Save your JSON example to a file, say ex.json and then

yq -y '.' ex.json

AAPL:
- shares: -75.088
  date: 11/27/2015
- shares: 75.088
  date: 11/26/2015

I had the same problem and I've already tried everything and nothing seemed to work until I just changed the 'host' value in config.php to:

 'host' => env('smtp.mailtrap.io'),

When I changed that it worked nicely, somehow it was using the default host " smtp.mailtrap.org" and ignoring the .env variable I was setting.

After making some test I realize that if I placed the env variable in this order it would worked as it shoulded:

MAIL_HOST=smtp.mailtrap.io

?MAIL_DRIVER=smtp

?MAIL_PORT=2525?

MAIL_USERNAME=xxxx

?MAIL_PASSWORD=xxx

?MAIL_ENCRYPTION=null

You want to use transform this will return a Series with the index aligned to the df so you can then add it as a new column:

In [74]:

df = pd.DataFrame({'Date': ['2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05', '2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05'], 'Sym': ['aapl', 'aapl', 'aapl', 'aapl', 'aaww', 'aaww', 'aaww', 'aaww'], 'Data2': [11, 8, 10, 15, 110, 60, 100, 40],'Data3': [5, 8, 6, 1, 50, 100, 60, 120]})
?
df['Data4'] = df['Data3'].groupby(df['Date']).transform('sum')
df
Out[74]:
   Data2  Data3        Date   Sym  Data4
0     11      5  2015-05-08  aapl     55

2     10      6  2015-05-06  aapl     66
3     15      1  2015-05-05  aapl    121

6    100     60  2015-05-06  aaww     66
7     40    120  2015-05-05  aaww    121

You need to run these two commands

php artisan cache:clear
php artisan config:cache

Check below code for converting json to array in PHP, If JSON is correct then json_decode() works well, and will return an array, But if malformed JSON, then It will return NULL,

<?php
function jsonDecode1($json){
    $arr = json_decode($json, true);
    return $arr;
}

// In case of malformed JSON, it will return NULL
var_dump( jsonDecode1($json) );

If malformed JSON, and you are expecting only array, then you can use this function,

<?php
function jsonDecode2($json){
    $arr = (array) json_decode($json, true);
    return $arr;
}

// In case of malformed JSON, it will return an empty array()
var_dump( jsonDecode2($json) );

If malformed JSON, and you want to stop code execution, then you can use this function,

<?php
function jsonDecode3($json){
    $arr = (array) json_decode($json, true);

    if(empty(json_last_error())){
        return $arr;
    }
    else{
        throw new ErrorException( json_last_error_msg() );
    }
}

// In case of malformed JSON, Fatal error will be generated
var_dump( jsonDecode3($json) );

You can use any function depends on your requirement,

I use simple grep inside function in bash script to receive properties from .properties file.

This properties file I use in two places - to setup dev environment and as application parameters.

I believe that grep may work slow in big loops but it solves my needs when I want to prepare dev environment.

Hope, someone will find this useful.

Example:

File: setup.sh

#!/bin/bash

ENV=${1:-dev}

function prop {
    grep "${1}" env/${ENV}.properties|cut -d'=' -f2
}

    -e STORAGE_BUCKET="$(prop 'app.storage.bucket')" \
    -v "$(prop 'app.data-path')/storage":/app/storage \
    myapp-storage:latest

docker create \

Usage:

It s already decoded in Python3, Try directly it should work.

Error message clearly says that source parameter is null. Source is the enumerable you are enumerating. In your case it is ListMetadataKor object. And its definitely null at the time you are filtering it second time. Make sure you never assign null to this list. Just check all references to this list in your code and look for assignments.

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

Use subscripting to access the value for a dictionary key. This will return an Optional:

let apple: String? = companies["AAPL"]

or

if let apple = companies["AAPL"] {
    // ...
}

You can also enumerate over all of the keys and values:

var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"]

for (key, value) in companies {
    print("\(key) -> \(value)")
}

Or enumerate over all of the values:

for value in Array(companies.values) {
    print("\(value)")
}

@IBAction func ImportImage(_ sender: Any)
{
    let image = UIImagePickerController()
    image.delegate = self

    image.sourceType = UIImagePickerController.SourceType.photoLibrary

    image.allowsEditing = false

    self.present(image, animated: true)
    {
        //After it is complete
    }


}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
    {
        myimage.image = image
    }
    else{
        //
    }
    self.dismiss(animated: true, completion: nil)

    do {
        try context.save()
    } catch {
        print("Could not save. \(error), \(error.localizedDescription)")
    }

}

Add UINavigationControllerDelegate, UIImagePickerControllerDelegate delegates in the class definition

In Swift 4 and 5. I created a closure variable containing two parameter dictionary and bool.

 var completionHandler:([String:Any], Bool)->Void = { dict, success  in
    if success {
      print(dict)
    }
  }

Calling the closure variable

self.completionHandler(["name":"Gurjinder singh"],true)

Note that Python3 does not read the html code as a string but as a bytearray, so you need to convert it to one with decode.

import urllib.request

fp = urllib.request.urlopen("http://www.python.org")
mybytes = fp.read()

mystr = mybytes.decode("utf8")
fp.close()

print(mystr)

Great question, and great answer by Benjamin, Kris, et al - many thanks!

I'm using this in a project and have created a module based on Benjamin Gruenwald's code. It's available on npmjs:

npm i -S promise-spread

Then in your code, do

require('promise-spread');

If you're using a library such as any-promise

var Promise = require('any-promise');
require('promise-spread')(Promise);

Maybe others find this useful, too!

For those who use Tomcat with Bitronix, this will fix the problem:

The error indicates that no handler could be found for your datasource 'jdbc/mydb', so you'll need to make sure your tomcat server refers to your bitronix configuration files as needed.

In case you're using btm-config.properties and resources.properties files to configure the datasource, specify these two JVM arguments in tomcat:

(if you already used them, make sure your references are correct):

• btm.root
• bitronix.tm.configuration

e.g.

-Dbtm.root="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59" 
-Dbitronix.tm.configuration="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59\conf\btm-config.properties" 

Now, restart your server and check the log.

not that hard,

if you take a look at the page source, you'll see that it uses to stream the audio via shoutcast.

this is the stream url

"StreamUrl": "http://stream.radiotime.com/listen.stream?streamIds=3244651&rti=c051HQVbfRc4FEMbKg5RRVMzRU9KUBw%2fVBZHS0dPF1VIExNzJz0CGQtRcX8OS0o0CUkYRFJDDW8LEVRxGAEOEAcQXko%2bGgwSBBZrV1pQZgQZZxkWCA4L%7e%7e%7e",

which returns a JSON like that:

{
    "Streams": [
        {
            "StreamId": 3244651,
            "Reliability": 92,
            "Bandwidth": 64,
            "HasPlaylist": false,
            "MediaType": "MP3",
            "Url": "http://mp3hdfm32.hala.jo:8132",
            "Type": "Live"
        }
    ]
}

i believe that's the url you need: http://mp3hdfm32.hala.jo:8132

this is the station WebSite

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

console.log(typeof json_data !== 'undefined'
    ? json_data.length : 'There is no spoon.');

...or more simply...

console.log(json_data ? json_data.length : 'json_data is null or undefined');

The gcc compiler is not in your $PATH. It means either you dont have gcc installed or it's not in your $PATH variable.

To install gcc use this: (run as root)

• Redhat base:

  yum groupinstall "Development Tools"
  

• Debian base:

  apt-get install build-essential
  

Did you check this line works perfectly & your string have value in it ?

string jsonString = sr.ReadToEnd();

if yes, try this code for last line:

ValueSet items = JsonConvert.DeserializeObject<ValueSet>(jsonString);

or if you have an array of json you can use list like this :

List<ValueSet> items = JsonConvert.DeserializeObject<List<ValueSet>>(jsonString);

good luck

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

You can use Uber's H3,point_dist() function to compute the spherical distance between two (lat, lng) points. We can set return unit ('km', 'm', or 'rads'). The default unit is Km.

Example :

import H3

coords_1 = (52.2296756, 21.0122287)
coords_2 = (52.406374, 16.9251681)
distance = h3.point_dist(coords_1,coords_2) #278.4584889328128

Hope this will usefull!

svg.selectAll("rect")
.attr('x',function(d,i){
    // get x coord
    console.log(this.getBBox().x, 'or', d3.select(this).attr('x'))
})
.attr('y',function(d,i){
    // get y coord
    console.log(this.getBBox().y)
})
.attr('dx',function(d,i){
    // get dx coord
    console.log(parseInt(d3.select(this).attr('dx')))
})

Tested and working 100%

public class MainActivity extends ActionBarActivity {
    Context context = this;
    MediaPlayer mp;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_layout);
        mp = MediaPlayer.create(context, R.raw.sound);
        final Button b = (Button) findViewById(R.id.Button);
        b.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                try {
                    if (mp.isPlaying()) {
                        mp.stop();
                        mp.release();
                        mp = MediaPlayer.create(context, R.raw.sound);
                    } mp.start();
                } catch(Exception e) { e.printStackTrace(); }
            }
        });
    }
}

This was all we had to do

if (mp.isPlaying()) {
    mp.stop();
    mp.release();
    mp = MediaPlayer.create(context, R.raw.sound);
}

If Apache was installed using NSIS installer it should have left an uninstaller. You should search inside Apache installation directory for executable named unistaller.exe or something like that. NSIS uninstallers support /S flag by default for silent uninstall. So you can run something like "C:\Program Files\<Apache installation dir here>\uninstaller.exe" /S

From NSIS documentation:

3.2.1 Common Options

/NCRC disables the CRC check, unless CRCCheck force was used in the script. /S runs the installer or uninstaller silently. See section 4.12 for more information. /D sets the default installation directory ($INSTDIR), overriding InstallDir and InstallDirRegKey. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.

Summary

With either string concatenation or string interpolation (via template literals).

Here with JavaScript template literal:

function geoPreview() {
    var lat = document.getElementById("lat").value;
    var long = document.getElementById("long").value;

    window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${lat}&lon=${long}&setLatLon=Set`;
}

Both parameters are unused and can be removed.

Remarks

String Concatenation

Join strings with the + operator:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=" + elemA + "&lon=" + elemB + "&setLatLon=Set";

String Interpolation

For more concise code, use JavaScript template literals to replace expressions with their string representations. Template literals are enclosed by `` and placeholders surrounded with ${}:

window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${elemA}&lon=${elemB}&setLatLon=Set`;

Template literals are available since ECMAScript 2015 (ES6).

I assumed the first DIV is #content :

<div id="content">
   <img src="@Url.Content("~/images/image1.bmp")" alt="" />
   <img src="@Url.Content("~/images/image2.bmp")" alt="" />
   <img src="@Url.Content("~/images/image3.bmp")" alt="" />
</div>

And CSS :

#content{
         width: 700px;
         display: block;
         height: auto;
     }
     #content > img{
        float: left; width: 200px;
        height: 200px;
        margin: 5px 8px;
     }

Use Like this:

Uri uri = Uri.parse(URL); //Declare your url here.

VideoView mVideoView  = (VideoView)findViewById(R.id.videoview)
mVideoView.setMediaController(new MediaController(this));       
mVideoView.setVideoURI(uri);
mVideoView.requestFocus();
mVideoView.start();

Another Method:

  String LINK = "type_here_the_link";
  VideoView mVideoView  = (VideoView) findViewById(R.id.videoview);
  MediaController mc = new MediaController(this);
  mc.setAnchorView(videoView);
  mc.setMediaPlayer(videoView);
  Uri video = Uri.parse(LINK);
  mVideoView.setMediaController(mc);
  mVideoView.setVideoURI(video);
  mVideoView.start();

If you are getting this error Couldn't open file on client side, trying server side Error in Android. and also Refer this. Hope this will give you some solution.

Given the answer hardartcore that worked for me with a small change and did not work before the change:

private Handler mHandler = new Handler();
MusicPlayer.this.runOnUiThread(new Runnable() {
     @Override
     public void run() {
          if(player != null){
               int mCurrentPosition = player.getCurrentPosition();//clear ' /1000 '
               seekBar.setProgress(mCurrentPosition);
          }
          mHandler.postDelayed(this, 1000);
      }
});



seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
          if(player != null && fromUser){
              player.seekTo(progress); // clear ' * 1000  '
          }
     }
});

purrr::flatten_*() is also a good option. the flatten_* functions add thin sanity checks and ensure type safety.

myList <- list('A'=1, 'B'=2, 'C'=3)

purrr::flatten_dbl(myList)
## [1] 1 2 3

I use this class for Audio play. If your audio location is raw folder.

Call method for play:

new AudioPlayer().play(mContext, getResources().getIdentifier(alphabetItemList.get(mPosition)
                        .getDetail().get(0).getAudio(),"raw", getPackageName()));

AudioPlayer.java class:

        if (mMediaPlayer != null) {
            mMediaPlayer.release();
            mMediaPlayer = null;

The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

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

It's because:

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

2) Fragment doesn't have runOnUiThread.

However, Activity does.

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

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

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

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

It seems that in lollipop and up (or maybe just a different WebView Version) that calling cprcrack's onHideCustomView() method does not work. It works if it is called from the exit fullscreen button but when you specifically call the method it will only exit fullscreen but the webView stays blank. A way around it is to simply add these lines of code to onHideCustomView():

String js = "javascript:";
js += "var _ytrp_html5_video = document.getElementsByTagName('video')[0];";
js += "_ytrp_html5_video.webkitExitFullscreen();";
webView.loadUrl(js);

This will notify the webView that fullscreen has exited.

Use geom_text , with aes label. You can play with hjust, vjust to adjust text position.

ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +geom_text(aes(label=Name),hjust=0, vjust=0)

EDIT: Label only values above a certain threshold:

  ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +
  geom_text(aes(label=ifelse(PTS>24,as.character(Name),'')),hjust=0,vjust=0)

I just saw this as a result of a network error / time-out on a flaky network. I could see the progress bar increasing after I got the bright idea of just retrying. Also saw HTTP Range requests on the download server with ever increasing offsets of a few megabytes (the entire app was about 44MB).

Had same problem - it was somewhere in the ca certificate, so I used the ca bundle used for curl, and it worked. You can download the curl ca bundle here: https://curl.haxx.se/docs/caextract.html

The classes which you are importing have to be on the classpath. So either the users of your Applet have to have the libraries in the right place or you simply provide those libraries by including them in your jar file. For example like this: Easiest way to merge a release into one JAR file

You should use only one mediaplayer object

                    mp.start();
                }

            });

From your FirstActivity call the SecondActivity using startActivityForResult() method

For example:

int LAUNCH_SECOND_ACTIVITY = 1
Intent i = new Intent(this, SecondActivity.class);
startActivityForResult(i, LAUNCH_SECOND_ACTIVITY);

In your SecondActivity set the data which you want to return back to FirstActivity. If you don't want to return back, don't set any.

For example: In SecondActivity if you want to send back data:

Intent returnIntent = new Intent();
returnIntent.putExtra("result",result);
setResult(Activity.RESULT_OK,returnIntent);
finish();

If you don't want to return data:

Intent returnIntent = new Intent();
setResult(Activity.RESULT_CANCELED, returnIntent);
finish();

Now in your FirstActivity class write following code for the onActivityResult() method.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == LAUNCH_SECOND_ACTIVITY) {
        if(resultCode == Activity.RESULT_OK){
            String result=data.getStringExtra("result");
        }
        if (resultCode == Activity.RESULT_CANCELED) {
            //Write your code if there's no result
        }
    }
}//onActivityResult

I had the same issue when forking with 'python'; the main reason is that the search path is relative, if you don't call g++ as /usr/bin/g++, it will not be able to work out the canonical paths to call cc1plus.

The answer was surprisingly simple. I had to add a Content-Type header in the POST request with a value of application/json. Without this header Jersey did not know what to do with the request body (in spite of the @Consumes(MediaType.APPLICATION_JSON) annotation)!

The problem you'll face is that there's two types of PEM formatted keys: PKCS8 and SSLeay. It doesn't help that OpenSSL seems to use both depending on the command:

The usual openssl genrsa command will generate a SSLeay format PEM. An export from an PKCS12 file with openssl pkcs12 -in file.p12 will create a PKCS8 file.

The latter PKCS8 format can be opened natively in Java using PKCS8EncodedKeySpec. SSLeay formatted keys, on the other hand, can not be opened natively.

To open SSLeay private keys, you can either use BouncyCastle provider as many have done before or Not-Yet-Commons-SSL have borrowed a minimal amount of necessary code from BouncyCastle to support parsing PKCS8 and SSLeay keys in PEM and DER format: http://juliusdavies.ca/commons-ssl/pkcs8.html. (I'm not sure if Not-Yet-Commons-SSL will be FIPS compliant)

Key Format Identification

By inference from the OpenSSL man pages, key headers for two formats are as follows:

PKCS8 Format

Non-encrypted: -----BEGIN PRIVATE KEY-----
Encrypted: -----BEGIN ENCRYPTED PRIVATE KEY-----

SSLeay Format

-----BEGIN RSA PRIVATE KEY-----

(These seem to be in contradiction to other answers but I've tested OpenSSL's output using PKCS8EncodedKeySpec. Only PKCS8 keys, showing ----BEGIN PRIVATE KEY----- work natively)

It does what you ask, SELECT 1 FROM table will SELECT (return) a 1 for every row in that table, if there were 3 rows in the table you would get

1
1
1

Take a look at Count(*) vs Count(1) which may be the issue you were described.

At the risk of sounding obvious, always check the spelling of your forward class files. Sometimes XCode (at least XCode 4.3.2) will turn a declaration green that's actually camel cased incorrectly. Like in this example:

"_OBJC_CLASS_$_RadioKit", referenced from:
  objc-class-ref in RadioPlayerViewController.o

If RadioKit was a class file and you make it a property of another file, in the interface declaration, you might see that

Radiokit *rk;

has "Radiokit" in green when the actual decalaration should be:

RadioKit *rk;

This error will also throw this type of error. Another example (in my case), is when you have _iPhone and _iphone extensions on your class names for universal apps. Once I changed the appropriate file from _iphone to the correct _iPhone, the errors went away.

"Fork" in this context means "Make a copy of their code so that I can add my own modifications". There's not much else to say. Every clone is essentially a fork, and it's up to the original to decide whether to pull the changes from the fork.

On Ubuntu, You can follow these steps to resolve the issue:

1. Create a directory named plugins inside $HOME/.mozilla, if it doesn't exist already

2. Create a symlink to libnpjp2.so inside this directory using this command:

   ln -s $JAVA_HOME/jre/lib/i386/libnpjp2.so $MOZILLA_HOME/plugins
   

   -or-

   ln -s $JAVA_HOME/jre/lib/amd64/libnpjp2.so $MOZILLA_HOME/plugins
   

   depending on whether you're using a 32 or 64 bit JVM installation. Moreover, $JAVA_HOME is the location of your JVM installation.

First convert the numeric value then add the 'S':

 select convert(varchar(10),StandardCost) +'S'
 from DimProduct where ProductKey = 212

This is what I use:

public enum Quality {ENOUGH,BETTER,BEST;
                     private static final int amount = EnumSet.allOf(Quality.class).size();
                     private static Quality[] val = new Quality[amount];
                     static{ for(Quality q:EnumSet.allOf(Quality.class)){ val[q.ordinal()]=q; } }
                     public static Quality fromInt(int i) { return val[i]; }
                     public Quality next() { return fromInt((ordinal()+1)%amount); }
                    }

I had a similar issue, and my solution is ugly, but it works:

void showCode() {
    hideRegisterMessage(); // Hides view 
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            showRegisterMessage(); // Shows view
        }
    }, 3000); // After 3 seconds
}

Ensure that there are no other adb processes running

There may be more than one adb process running on the system. Tools such as the Android Reverse Tether may use their own version of the adb tool, hence the version in memory may conflict with the version run from the command line (via the path variable).

Windows

In Windows, press CTL+Shift+ESC to access Task Manager, sort in the Image Name column, then kill all instances of adb.exe by right-clicking, and choosing End Process. Note that there are multiple instances of adb.exe below:

Linux (Android)

In a Linux environment, just use the kill -9 command. Something like this worked on an Android device running adb (use ps output, search using grep for a process starting with adb, get the Process ID from the adb process(es), and send that ID to the kill -9 command):

kill -9  $(ps  | grep "S adb" | busybox awk '{print $2}')

Then, restart adb

Once the adb processes - and thus conflicts - are resolved, then retry running adb from the command-line again:

adb start-server

This works for me on [{"id":"data"},{"id":"data"}]

function getObjects(obj, key, val) 
{
    var newObj = false; 
    $.each(obj, function()
    {
        var testObject = this; 
        $.each(testObject, function(k,v)
        {
            //alert(k);
            if(val == v && k == key)
            {
                newObj = testObject;
            }
        });
    });

    return newObj;
}

I use Butterknife with switch-case to handle this kind of cases:

    @OnClick({R.id.button_bireysel, R.id.button_kurumsal})
        public void onViewClicked(View view) {
            switch (view.getId()) {


                case R.id.button_bireysel:
 //Do something

                    break;
                case R.id.button_kurumsal:

     //Do something

                    break;

            }
        }

But the thing is there is no default case and switch statement falls through

I had pretty much the same question. After some research, I think that if you want to play the default system "notification sound", you pretty much have to display a notification and tell it to use the default sound. And there's something to be said for the argument in some of the other answers that if you're playing a notification sound, you should be presenting some notification message as well.

However, a little tweaking of the notification API and you can get close to what you want. You can display a blank notification and then remove it automatically after a few seconds. I think this will work for me; maybe it will work for you.

I've created a set of convenience methods in com.globalmentor.android.app.Notifications.java which allow you create a notification sound like this:

Notifications.notify(this);

The LED will also flash and, if you have vibrate permission, a vibration will occur. Yes, a notification icon will appear in the notification bar but will disappear after a few seconds.

At this point you may realize that, since the notification will go away anyway, you might as well have a scrolling ticker message in the notification bar; you can do that like this:

Notifications.notify(this, 5000, "This text will go away after five seconds.");

There are many other convenience methods in this class. You can download the whole library from its Subversion repository and build it with Maven. It depends on the globalmentor-core library, which can also be built and installed with Maven.

SET session_replication_role = replica; 

It doesn't work with PostgreSQL 9.4 on my Linux machine if i change a table through table editor in pgAdmin and works if i change table through ordinary query. Manual changes in pg_trigger table also don't work without server restart but dynamic query like on postgresql.nabble.com ENABLE / DISABLE ALL TRIGGERS IN DATABASE works. It could be useful when you need some tuning.

For example if you have tables in a particular namespace it could be:

create or replace function disable_triggers(a boolean, nsp character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_namespace n
        join pg_class c on c.relnamespace = n.oid and c.relhastriggers = true
        where n.nspname = nsp
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

If you want to disable all triggers with certain trigger function it could be:

create or replace function disable_trigger_func(a boolean, f character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_proc p 
        join pg_trigger t on t.tgfoid = p.oid
        join pg_class c on c.oid = t.tgrelid
        where p.proname = f
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

PostgreSQL documentation for system catalogs

There are another control options of trigger firing process:

ALTER TABLE ... ENABLE REPLICA TRIGGER ... - trigger will fire in replica mode only.

ALTER TABLE ... ENABLE ALWAYS TRIGGER ... - trigger will fire always (obviously)

I got the same error. I solved it moving the file applicationContext.xmlin a

sub-folder of the srcfolder. e.g:

context = new ClassPathXmlApplicationContext("/com/ejemplo/dao/applicationContext.xml");

To add to @Hima's answer, if you want to modify a current x or y limit you could use the following.

import numpy as np # you probably alredy do this so no extra overhead
fig, axes = plt.subplot()
axes.plot(data[:,0], data[:,1])
xlim = axes.get_xlim()
# example of how to zoomout by a factor of 0.1
factor = 0.1 
new_xlim = (xlim[0] + xlim[1])/2 + np.array((-0.5, 0.5)) * (xlim[1] - xlim[0]) * (1 + factor) 
axes.set_xlim(new_xlim)

I find this particularly useful when I want to zoom out or zoom in just a little from the default plot settings.

I made a solution based in part by the information above. I just set the titleLabel.text to the string I want to pass, and set the titleLabel.hidden = YES

Like this :

    UIButton *imageclick = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
    imageclick.frame = photoframe;
    imageclick.titleLabel.text = [NSString stringWithFormat:@"%@.%@", ti.mediaImage, ti.mediaExtension];
    imageclick.titleLabel.hidden = YES;

This way, there is no need for a inheritance or category and there is no memory leak

Okay, I don't foresee any more answers on this one, so what I ended up going with for now is just a solution for rectangular images. I've used the following NinePatch:



along with the appropriate padding in XML:

<ImageView
        android:id="@+id/image_test"
        android:background="@drawable/drop_shadow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="6px"
        android:paddingTop="4px"
        android:paddingRight="8px"
        android:paddingBottom="9px"
        android:src="@drawable/pic1"
        />

to get a fairly good result:



Not ideal, but it'll do.

I solved the problem by splitting gif animations into frames before saving it to phone, so I would not have to deal with it in Android.

Then I download every frame onto phone, create Drawable from it and then create AnimationDrawable - very similar to example from my question

If I remember well, I had the same kind of issue when loading stuff from the asset folder but with a database. It seems that the stuff in your asset folder can have 2 stats : compressed or not.
If it is compressed, then you are allowed 1 Mo of memory to uncompress it, otherwise you will get this kind of exception. There are several bug reports about that because the documentation is not clear. So if you still want to to use your format, you have to either use an uncompressed version, or give an extension like .mp3 or .png to your file. I know it's a bit crazy but I load a database with a .mp3 extension and it works perfectly fine. This other solution is to package your application with a special option to tell it not to compress certain extension. But then you need to build your app manually and add "zip -0" option.
The advantage of an uncompressed assest is that the phase of zip-align before publication of an application will align the data correctly so that when loaded in memory it can be directly mapped.

So, solutions :

• change the extension of the file to .mp3 or .png and see if it works
• build your app manually and use the zip-0 option

If a user has never set an alarm on their phone, the TYPE_ALARM can return null. You can account for this with:

Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

if(alert == null){
    // alert is null, using backup
    alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    // I can't see this ever being null (as always have a default notification)
    // but just incase
    if(alert == null) {  
        // alert backup is null, using 2nd backup
        alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);                
    }
}

This is the easiest one , Just define a Function and then a Tkinter Label & Button . Pressing the Button changes the text in the label. The difference that you would when defining the Label is that use the text variable instead of text. Code is tested and working.

    from tkinter import *
    master = Tk()
    
    def change_text():
        my_var.set("Second click")
    
    my_var = StringVar()
    my_var.set("First click")
    label = Label(mas,textvariable=my_var,fg="red")
    button = Button(mas,text="Submit",command = change_text)
    button.pack()
    label.pack()
    
    master.mainloop()

You use the word initialize so it's unclear if this is one-time assignment or can happen multiple times.

If you just need a one time initialization, you can put it in the constructor and use the two iterator vector constructor:

Foo::Foo(double* w, int len) : w_(w, w + len) { }

Otherwise use assign as previously suggested:

void set_data(double* w, int len)
{
    w_.assign(w, w + len);
}

function showHide(id) {
      var hidden= ("none" == $( "#".concat(id) ).css("display"));
      if(hidden){
          $( "#".concat(id) ).show(1000);

For my senior design, we programmed a Canon camera to produce depth maps using CHDK. Most of the code was written in C, but you have to interface to it with this ridiculous language called uBasic. Basically, it wasn't implemented with a proper parser, and so variables can only be 1 letter, it's insanely slow, and if you make a mistake, the camera just shuts off.

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char
    else:
        new_s += ' '

Sample white-list using a generator-expression:

whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

Just to complete the above methods I tried a variant with the fileinput module:

import fileinput as fi   
def filecount(fname):
        for line in fi.input(fname):
            pass
        return fi.lineno()

And passed a 60mil lines file to all the above stated methods:

mapcount : 6.1331050396
simplecount : 4.588793993
opcount : 4.42918205261
filecount : 43.2780818939
bufcount : 0.170812129974

It's a little surprise to me that fileinput is that bad and scales far worse than all the other methods...

The reason for this is the non-existent Backend Service:

The Geocoder class requires a backend service that is not included in the core android framework. The Geocoder query methods will return an empty list if there no backend service in the platform.

There's a pretty good article and library on CodeProject by Yogesh Jagota:

Excel XML Import-Export Library

I've used it to export data from SQL queries and other data sources to Excel - works just fine for me.

Cheers

I would do it using a for loop as shown below :

def determine_period(universe_array):
    tmp = universe_array
    for period in xrange(1, 13):
        tmp = apply_rules(tmp)
        if numpy.array_equal(tmp, universe_array):
            return period
    return 0

I would imagine the safest way would just be to parse for <>s, no? Loop through the entire string, and copy anything not enclosed in <>s to a new string.

Faster Than ORDER BY RAND()

I tested this method to be much faster than ORDER BY RAND(), hence it runs in O(n) time, and does so impressively fast.

From http://technet.microsoft.com/en-us/library/ms189108%28v=sql.105%29.aspx:

Non-MSSQL version -- I did not test this

SELECT * FROM Sales.SalesOrderDetail
WHERE 0.01 >= RAND()

MSSQL version:

SELECT * FROM Sales.SalesOrderDetail
WHERE 0.01 >= CAST(CHECKSUM(NEWID(), SalesOrderID) & 0x7fffffff AS float) / CAST (0x7fffffff AS int)

This will select ~1% of records. So if you need exact # of percents or records to be selected, estimate your percentage with some safety margin, then randomly pluck excess records from resulting set, using the more expensive ORDER BY RAND() method.

Even Faster

I was able to improve upon this method even further because I had a well-known indexed column value range.

For example, if you have an indexed column with uniformly distributed integers [0..max], you can use that to randomly select N small intervals. Do this dynamically in your program to get a different set for each query run. This subset selection will be O(N), which can many orders of magnitude smaller than your full data set.

In my test I reduced the time needed to get 20 (out 20 mil) sample records from 3 mins using ORDER BY RAND() down to 0.0 seconds!

Volatile and Atomic are two different concepts. Volatile ensures, that a certain, expected (memory) state is true across different threads, while Atomics ensure that operation on variables are performed atomically.

Take the following example of two threads in Java:

Thread A:

value = 1;
done = true;

Thread B:

if (done)
  System.out.println(value);

Starting with value = 0 and done = false the rule of threading tells us, that it is undefined whether or not Thread B will print value. Furthermore value is undefined at that point as well! To explain this you need to know a bit about Java memory management (which can be complex), in short: Threads may create local copies of variables, and the JVM can reorder code to optimize it, therefore there is no guarantee that the above code is run in exactly that order. Setting done to true and then setting value to 1 could be a possible outcome of the JIT optimizations.

volatile only ensures, that at the moment of access of such a variable, the new value will be immediately visible to all other threads and the order of execution ensures, that the code is at the state you would expect it to be. So in case of the code above, defining done as volatile will ensure that whenever Thread B checks the variable, it is either false, or true, and if it is true, then value has been set to 1 as well.

As a side-effect of volatile, the value of such a variable is set thread-wide atomically (at a very minor cost of execution speed). This is however only important on 32-bit systems that i.E. use long (64-bit) variables (or similar), in most other cases setting/reading a variable is atomic anyways. But there is an important difference between an atomic access and an atomic operation. Volatile only ensures that the access is atomically, while Atomics ensure that the operation is atomically.

Take the following example:

i = i + 1;

No matter how you define i, a different Thread reading the value just when the above line is executed might get i, or i + 1, because the operation is not atomically. If the other thread sets i to a different value, in worst case i could be set back to whatever it was before by thread A, because it was just in the middle of calculating i + 1 based on the old value, and then set i again to that old value + 1. Explanation:

Assume i = 0
Thread A reads i, calculates i+1, which is 1
Thread B sets i to 1000 and returns
Thread A now sets i to the result of the operation, which is i = 1

Atomics like AtomicInteger ensure, that such operations happen atomically. So the above issue cannot happen, i would either be 1000 or 1001 once both threads are finished.

A terser way, either with rev :

x[!(!duplicated(x) & rev(!duplicated(rev(x))))]

... rather than fromLast:

x[!(!duplicated(x) & !duplicated(x, fromLast = TRUE))]

... and as a helper function to provide either logical vector or elements from original vector :

duplicates <- function(x, as.bool = FALSE) {
    is.dup <- !(!duplicated(x) & rev(!duplicated(rev(x))))
    if (as.bool) { is.dup } else { x[is.dup] }
}

Treating vectors as data frames to pass to table is handy but can get difficult to read, and the data.table solution is fine but I'd prefer base R solutions for dealing with simple vectors like IDs.

Sometimes, a row contain double quote column. When csv reader try read this row, not understood end of column and fire this raise. Solution is below:

To set a default value to a column, try this:

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status SET DEFAULT 'default value'

1. Remove this line of code: For i = 1 To DatDiff. A For loop must have the word NEXT
2. Also, remove this line of code: StrSQL = StrSQL & "SELECT 'Test'" because its making Access look at your final SQL statement like this; INSERT INTO Test (Start_Date) VALUES ('" & InDate & "' );SELECT 'Test' Notice the semicolon in the middle of the SQL statement (should always be at the end. its by the way not required. you can also omit it). also, there is no space between the semicolon and the key word SELECT

in summary: remove those two lines of code above and your insert statement will work fine. You can the modify the code it later to suit your specific needs. And by the way, some times, you have to enclose dates in pounds signs like #

tl;dr version: use ~/.zshrc

And read the man page to understand the differences between:

~/.zshrc, ~/.zshenv and ~/.zprofile.

Regarding my comment

In my comment attached to the answer kev gave, I said:

This seems to be incorrect - /etc/profile isn't listed in any zsh documentation I can find.

This turns out to be partially incorrect: /etc/profile may be sourced by zsh. However, this only occurs if zsh is "invoked as sh or ksh"; in these compatibility modes:

The usual zsh startup/shutdown scripts are not executed. Login shells source /etc/profile followed by $HOME/.profile. If the ENV environment variable is set on invocation, $ENV is sourced after the profile scripts. The value of ENV is subjected to parameter expansion, command substitution, and arithmetic expansion before being interpreted as a pathname. [man zshall, "Compatibility"].

The ArchWiki ZSH link says:

At login, Zsh sources the following files in this order:
/etc/profile
This file is sourced by all Bourne-compatible shells upon login

This implys that /etc/profile is always read by zsh at login - I haven't got any experience with the Arch Linux project; the wiki may be correct for that distribution, but it is not generally correct. The information is incorrect compared to the zsh manual pages, and doesn't seem to apply to zsh on OS X (paths in $PATH set in /etc/profile do not make it to my zsh sessions).

To address the question:

where exactly should I be placing my rvm, python, node etc additions to my $PATH?

Generally, I would export my $PATH from ~/.zshrc, but it's worth having a read of the zshall man page, specifically the "STARTUP/SHUTDOWN FILES" section - ~/.zshrc is read for interactive shells, which may or may not suit your needs - if you want the $PATH for every zsh shell invoked by you (both interactive and not, both login and not, etc), then ~/.zshenv is a better option.

Is there a specific file I should be using (i.e. .zshenv which does not currently exist in my installation), one of the ones I am currently using, or does it even matter?

There's a bunch of files read on startup (check the linked man pages), and there's a reason for that - each file has it's particular place (settings for every user, settings for user-specific, settings for login shells, settings for every shell, etc).
Don't worry about ~/.zshenv not existing - if you need it, make it, and it will be read.

.bashrc and .bash_profile are not read by zsh, unless you explicitly source them from ~/.zshrc or similar; the syntax between bash and zsh is not always compatible. Both .bashrc and .bash_profile are designed for bash settings, not zsh settings.

    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

I think you are looking for this function:

http://doc.qt.io/qt-5/qdatetime.html#toTime_t

uint QDateTime::toTime_t () const

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).

On systems that do not support time zones, this function will behave as if local time were Qt::UTC.

See also setTime_t().

I'm using contentEditable to allow rich text editing in my app. I don't know how it slips through, but when an image is inserted, and then resized (by dragging the anchors on its side), it generates something like this:

  <img style="width:55px;height:55px" width="100" height="100" src="pic.gif" border=0/>

(subsequent testing shown that inserted images did not contain this "rogue" style attr+param).

When rendered by the browser (IE7), the width and height in the style overrides the img width/height param (so the image is shown like how I wanted it.. resized to 55px x 55px. So everything went well so it seems.

When I output the page to a ms-word document via setting the mime type application/msword or pasting the browser rendering to msword document, all the images reverted back to its default size. I finally found out that msword is discarding the style and using the img width and height tag (which has the value of the original image size).

Took me a while to found this out. Anyway... I've coded a javascript function to traverse all tags and "transferring" the img style.width and style.height values into the img.width and img.height, then clearing both the values in style, before I proceed saving this piece of html/richtext data into the database.

cheers.

opps.. my answer is.. no. leave both attributes directly under img, rather than style.

If the primary key happens to be an auto_increment value, you have to remove the auto increment, then drop the primary key then re-add the auto-increment

ALTER TABLE `xx`
MODIFY `auto_increment_field` INT, 
DROP PRIMARY KEY, 
ADD PRIMARY KEY (new_primary_key);

then add back the auto increment

ALTER TABLE `xx` ADD INDEX `auto_increment_field` (auto_increment_field),
MODIFY `auto_increment_field` int auto_increment;

then set auto increment back to previous value

ALTER TABLE `xx` AUTO_INCREMENT = 5;

I personally like new lines at the end of source code files.

It may have its origin with Linux or all UNIX systems for that matter. I remember there compilation errors (gcc if I'm not mistaken) because source code files did not end with an empty new line. Why was it made this way one is left to wonder.

Besides maintainability, the first way eliminates possibility of accident global variables creation:

(function () {
var variable1 = "Hello, World!" // Semicolon is missed out accidentally
var variable2 = "Testing..."; // Still a local variable
var variable3 = 42;
}());

While the second way is less forgiving:

(function () {
var variable1 = "Hello, World!" // Comma is missed out accidentally
    variable2 = "Testing...", // Becomes a global variable
    variable3 = 42; // A global variable as well
}());

you should android sdk manager install 4.2 api 17 -> ARM EABI v7a System Image

if not installed ARM EABI v7a System Image, you should install all.

My solution:

import collections


def flatten(x):
    if isinstance(x, collections.Iterable):
        return [a for i in x for a in flatten(i)]
    else:
        return [x]

A little more concise, but pretty much the same.

AutoScroll is really the solution! You just have to set AutoScrollMargin to 0, 1000 or something like this, then use it to scroll down and add buttons and items there!

My DBA asked me when I asked about the best way to store GUIDs for my objects why I needed to store 16 bytes when I could do the same thing in 4 bytes with an Integer. Since he put that challenge out there to me I thought now was a good time to mention it. That being said...

You can store a guid as a CHAR(16) binary if you want to make the most optimal use of storage space.

HI you can try this...

Try..

$Ad | Sort-Object -Property sn, givenName | Select * | Export-Csv c:\scripts\ceridian\NoClockNumber_2013_02_12.csv -NoTypeInformation

Or

$Ad = Get-ADUser -SearchBase "OU=OUi,DC=company,DC=com"  -Filter * -Properties employeeNumber | ? {$_.employeenumber -eq $null}
$Ad | Sort-Object -Property sn, givenName | Select * | Export-Csv c:\scripts\cer

Hope it works for you.

Yes. Please see the man page of bash ( the first thing you go to ) under Special Parameters

Special Parameters

The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed.

* Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

@ Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

I got the same error message. In my case, it was due to not using quotes.

Although the column was supposed to have only numbers, it was a Varchar column, and one of the rows had a letter in it.

So I was doing this:

select * from mytable where myid = 1234

While I should be doing this:

select * from mytable where myid = '1234'

If the column had all numbers, the conversion would have worked, but not in this case.

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

To get size of viewport on load and on resize (based on SimaWB response):

function getViewport() {
    var viewportWidth = $(window).width();
    var viewportHeight = $(window).height();
    $('#viewport').html('Viewport: '+viewportWidth+' x '+viewportHeight+' px');
}

getViewport();

$(window).resize(function() {
    getViewport()
});

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

Note: As mentioned in the comments this answer refers to the steps needed with older versions of git. Git now has native support for moving submodules:

Since git 1.8.5, git mv old/submod new/submod works as expected and does all the plumbing for you. You might want to use git 1.9.3 or newer, because it includes fixes for submodule moving.

The process is similar to how you'd remove a submodule (see How do I remove a submodule?):

1. Edit .gitmodules and change the path of the submodule appropriately, and put it in the index with git add .gitmodules.
2. If needed, create the parent directory of the new location of the submodule (mkdir -p new/parent).
3. Move all content from the old to the new directory (mv -vi old/parent/submodule new/parent/submodule).
4. Make sure Git tracks this directory (git add new/parent).
5. Remove the old directory with git rm --cached old/parent/submodule.
6. Move the directory .git/modules/old/parent/submodule with all its content to .git/modules/new/parent/submodule.
7. Edit the .git/modules/new/parent/config file, make sure that worktree item points to the new locations, so in this example it should be worktree = ../../../../../new/parent/module. Typically there should be two more .. than directories in the direct path in that place.

8. Edit the file new/parent/module/.git, make sure that the path in it points to the correct new location inside the main project .git folder, so in this example gitdir: ../../../.git/modules/new/parent/submodule.

   git status output looks like this for me afterwards:

   # On branch master
   # Changes to be committed:
   #   (use "git reset HEAD <file>..." to unstage)
   #
   #       modified:   .gitmodules
   #       renamed:    old/parent/submodule -> new/parent/submodule
   #
   

9. Finally, commit the changes.

After jQuery 1.6, using promise seems like a better option.

var $div1 = $('#div1');
var fadeOutDone = $div1.fadeOut().promise();
// do your logic here, e.g.fetch your 2nd image url
$.get('secondimageinfo.json').done(function(data){
  fadeoOutDone.then(function(){
    $div1.html('<img src="' + data.secondImgUrl + '" alt="'data.secondImgAlt'">');
    $div1.fadeIn();
  });
});

this's my function, convert object or array to json

function obj2json(_data){
    str = '{ ';
    first = true;
    $.each(_data, function(i, v) { 
        if(first != true)
            str += ",";
        else first = false;
        if ($.type(v)== 'object' )
            str += "'" + i + "':" + obj2arr(v) ;
        else if ($.type(v)== 'array')
            str += "'" + i + "':" + obj2arr(v) ;
        else{
            str +=  "'" + i + "':'" + v + "'";
        }
    });
    return str+= '}';
}

i just edit to v0.2 ^.^

 function obj2json(_data){
    str = (($.type(_data)== 'array')?'[ ': '{ ');
    first = true;
    $.each(_data, function(i, v) { 
        if(first != true)
            str += ",";
        else first = false;
        if ($.type(v)== 'object' )
            str += '"' + i + '":' + obj2json(v) ;
        else if ($.type(v)== 'array')
            str += '"' + i + '":' + obj2json(v) ;
        else{
            if($.type(_data)== 'array')
                str += '"' + v + '"';
            else
                str +=  '"' + i + '":"' + v + '"';
        }
    });
    return str+= (($.type(_data)== 'array')? ' ] ':' } ');;
}

I had a similar problem, which turned out to be caused by missing double quotes off the table and schema name.

Use a smarty template for your stuff then just set the POST array as a smarty array and open the template. In the template just echo out the array so if it passes:

if(correct){
    header("Location: passed.php");
} else {
    $smarty->assign("variables", $_POST);
    $smarty->display("register_error.php");
    exit;
}

I have not tried this yet but I am going to try it as a solution and will let you know what I find. But of course this method assumes that you are using smarty.

If not you can just recreate your form there on the error page and echo info into the form or you could send back non important data in a get from and get it

ex.

register.php?name=mr_jones&address==......
echo $_GET[name];

you can just use

ls > filenames.txt

(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd to go to that folder first, or you can ls ~/docs > filenames.txt

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

The warning message

[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

means that you somehow passed -P pom.xml to Maven which means "there is a profile called pom.xml; find it and activate it". Check your environment and your settings.xml for this flag and also look at all <profile> elements inside the various XML files.

Usually, mvn help:effective-pom is also useful to see what the real POM would look like.

Now the error means that you tried to configure Maven to build Java 8 code but you're not using a Java 8 runtime. Solutions:

1. Install Java 8
2. Make sure Maven uses Java 8 if you have it installed. JAVA_HOME is your friend
3. Configure the Java compiler in your pom.xml to a Java version which you actually have.

I've found the answer regarding how to do this myself. Inside the model code, just put:

For Rails <= 2:

include ActionController::UrlWriter

For Rails 3:

include Rails.application.routes.url_helpers

This magically makes thing_path(self) return the URL for the current thing, or other_model_path(self.association_to_other_model) return some other URL.

Adding Quotes

I started using this quick and dirty function in my .vimrc:

vnoremap q <esc>:call QuickWrap("'")<cr>
vnoremap Q <esc>:call QuickWrap('"')<cr>

function! QuickWrap(wrapper)
  let l:w = a:wrapper
  let l:inside_or_around = (&selection == 'exclusive') ? ('i') : ('a')
  normal `>
  execute "normal " . inside_or_around . escape(w, '\')
  normal `<
  execute "normal i" . escape(w, '\')
  normal `<
endfunction

So now, I visually select whatever I want (typically via viw - visually select inside word) in quotes and press Q for double quotes, or press q for single quotes.

Removing Quotes

vnoremap s <esc>:call StripWrap()<cr>

function! StripWrap()
  normal `>x`<x
endfunction

I use vim-textobj-quotes so that vim treats quotes as a text objects. This means I can do vaq (visually select around quotes. This finds the nearest quotes and visually selects them. (This is optional, you can just do something like f"vww). Then I press s to strip the quotes from the selection.

Changing Quotes

KISS. I remove quotes then add quotes. For example, to replace single quotes with double quotes, I would perform the steps: 1. remove single quotes: vaqs, 2. add new quotes: vwQ.

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

With Excel 2013, I have encountered the same problem, but it seems related to some (self-made) Add-Ins I'm using, which add a tab to the ribbon. After unhooking these AddIns in the Options > Add-Ins > Goto: Exce-Add-Ins > Add_Ins Box and restarting Excel (!), all charts in the workbook kept updating immediately. But as soon as I activate (hook) one of these Add-Ins, none of the charts would update anymore. This issue does not show up with other Add-Ins (like e.g. Solver), so I still have to find out if it is caused by the Add-In creating an additional Tab in the ribbon, or just any Add-In of .xlam - type.

Only by help of following workaround code I could persuade the charts to do their job:

Dim chtChart As ChartObject

For Each chtChart In ActiveSheet.ChartObjects
   chtChart.Chart.ChartWizard
Next chtChart

Strange enough, the .Chart.Refresh - method didn't work either, but .Chart.ChartWizard did, though no parameters are given so it doesn't change anything!

(And yes, the calculation method of the workbook was / still is automatic)

update (2019-09-17):

Since another (3rd party) Add-In did NOT prevent any charts from updating, I plunged into some further research, disabled all code, deleted all XML-contents of the customUI - ribbon and removed all relations to external libraries (as far as the VBE let me do). Still I could reliably prevent all charts from updating just by activating this now completely useless Add-In.

As a last try, I re-built the Add-In from scratch by copying all code into a fresh .xlam - file, set all required library relations and finally added the XML-code for the ribbon with the customUI - editor.

And behold!: now all charts kept updating :-D

So - without proof - I just can guess that my old AddIn (originally of 2011, so probably done with Excel 2007 or 2010) was not completely compatible with Excel 2013. So it's always a good idea to do a new setup / re-create any AddIn with the present version of Excel ;-)

Good luck!

You could do it in one line (useful for ci-environments):

taskkill /fi "Services eq SERVICE_NAME" /F

In my case this was happening a lot in my development and test environments. After trying all of the above solutions without any success I found that I was able to fix this problem by deleting all session cookies. The web developer extension makes this very easy to do. I mostly use Firefox for testing and development, but this also happened while testing in Chrome. The fix also worked in Chrome.

I haven't had to do this yet in the production environment and have not received any reports of people not being able to log in. This also only seemed to happen after making the session cookies to be secure. It never happened in the past when they were not secure.

This did the job for me,

import org.apache.commons.lang.StringEscapeUtils;
...
String decodedXML= StringEscapeUtils.unescapeHtml(encodedXML);

or

import org.apache.commons.lang3.StringEscapeUtils;
...
String decodedXML= StringEscapeUtils.unescapeHtml4(encodedXML);

I guess its always better to use the lang3 for obvious reasons. Hope this helps :)

If you happened to run npm install command on Windows, first make sure you open your command prompt with Administration Privileges. That's what solved the issue for me.

Val means its final, cannot be reassigned

Whereas, Var can be reassigned later.

The "wipe user data" option finally solved my problem. just wipe user data every time you start the emulator. This always works for me! I use windows 8 x64 , eclipse

Initialize instance:

private String imagePath;
private List<String> imagePathList;

In onActivityResult You have to write this, If-else 2 block. One for single image and another for multiple image.

if (requestCode == GALLERY_CODE && resultCode == RESULT_OK  && data != null){

    imagePathList = new ArrayList<>();

    if(data.getClipData() != null){

        int count = data.getClipData().getItemCount();
        for (int i=0; i<count; i++){

            Uri imageUri = data.getClipData().getItemAt(i).getUri();
            getImageFilePath(imageUri);
        }
    }
    else if(data.getData() != null){

        Uri imgUri = data.getData();
        getImageFilePath(imgUri);
    }
}

Most important part, Get Image Path from uri:

public void getImageFilePath(Uri uri) {

    File file = new File(uri.getPath());
    String[] filePath = file.getPath().split(":");
    String image_id = filePath[filePath.length - 1];

    Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    if (cursor!=null) {
        cursor.moveToFirst();
        imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        imagePathList.add(imagePath);
        cursor.close();
    }
}

Hope this can help you.

There is no mention about nine-patch files here. Yes, you have to create the file, however it's quite easy job and it's really "cross-version and transparency supporting" solution. If the file is placed to the drawable-nodpi directory, it works px based, and in the drawable-mdpi works approximately as dp base (thanks to resample).

Example file for the original question (border-right:1px solid red;) is here:

http://ge.tt/517ZIFC2/v/3?c

Just place it to the drawable-nodpi directory.

Agree with the @jon answer. Just added modified the path to create the log directory inside the root

 function wh_log($log_msg) {
    $log_filename = $_SERVER['DOCUMENT_ROOT']."/log";
    if (!file_exists($log_filename))
    {
        // create directory/folder uploads.
        mkdir($log_filename, 0777, true);
    }
    $log_file_data = $log_filename.'/log_' . date('d-M-Y') . '.log';
    file_put_contents($log_file_data, $log_msg . "\n", FILE_APPEND);
}

just added $_SERVER['DOCUMENT_ROOT']

Very nice question, first we need to on the IDENTITY_INSERT for the specific table, after that run the insert query (Must specify the column name).

Note: After edit the the identity column, don't forget to off the IDENTITY_INSERT. If you not done, you cannot able to Edit the identity column for any other table.

SET IDENTITY_INSERT Emp_tb_gb_Menu ON
     INSERT Emp_tb_gb_Menu(MenuID) VALUES (68)
SET IDENTITY_INSERT Emp_tb_gb_Menu OFF

Use the left function:

QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "

Also have a look at mid() if you want more control.

Although it's possible to have multiple voicemail accounts, when calling from your own number, carriers route you to voicemail. So, TelephonyManager.getVoiceMailNumber() or TelephonyManager.getCompleteVoiceMailNumber(), depending on the flavor you need.

Hope this helps.

This answer is for react-router-4. You can wrap all the routes in Switch block, which functions just like the switch-case expression, and renders the component with the first matched route. eg)

<Switch>
      <Route path="/" component={home}/>
      <Route path="/home" component={home}/>
      <Route component={GenericNotFound}/> {/* The Default not found component */}
</Switch>

When to use exact

Without exact:

<Route path='/home'
       component = {Home} />

{/* This will also work for cases like https://<domain>/home/anyvalue. */}

With exact:

<Route exact path='/home'
       component = {Home} />

{/* 
     This will NOT work for cases like https://<domain>/home/anyvalue. 
     Only for https://<url>/home and https://<domain>/home/
*/}

Now if you are accepting routing parameters, and if it turns out incorrect, you can handle it in the target component itself. eg)

<Route exact path='/user/:email'
       render = { (props) => <ProfilePage {...props} user={this.state.user} />} />

Now in ProfilePage.js

if(this.props.match.params.email != desiredValue)
{
   <Redirect to="/notFound" component = {GenericNotFound}/>
   //Or you can show some other component here itself.
}

For more details you can go through this code:

App.js

ProfilePage.js

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;

and you leave it null (0) when persisting. (null if you use the Integer / Long wrappers)

In some cases the AUTO strategy is resolved to SEQUENCE rathen than to IDENTITY or TABLE, so you might want to manually set it to IDENTITY or TABLE (depending on the underlying database).

It seems SEQUENCE + specifying the sequence name worked for you.

for everything related to Python's style guide: i'd recommend you read PEP8.

To answer your question:

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

You don't need CSS for this.

     <img src="abc"/>

now with link:

     <a href="#myLink"><img src="abc"/></a>

Or with jquery, later on, you can use the wrap property, see these questions answer:

how to add a link to an image using jquery?

You can't depend on the file having a BOM. UTF-8 doesn't require it. And non-Unicode encodings don't even have a BOM. There are, however, other ways to detect the encoding.

UTF-32

BOM is 00 00 FE FF (for BE) or FF FE 00 00 (for LE).

But UTF-32 is easy to detect even without a BOM. This is because the Unicode code point range is restricted to U+10FFFF, and thus UTF-32 units always have the pattern 00 {00-10} xx xx (for BE) or xx xx {00-10} 00 (for LE). If the data has a length that's a multiple of 4, and follows one of these patterns, you can safely assume it's UTF-32. False positives are nearly impossible due to the rarity of 00 bytes in byte-oriented encodings.

US-ASCII

No BOM, but you don't need one. ASCII can be easily identified by the lack of bytes in the 80-FF range.

UTF-8

BOM is EF BB BF. But you can't rely on this. Lots of UTF-8 files don't have a BOM, especially if they originated on non-Windows systems.

But you can safely assume that if a file validates as UTF-8, it is UTF-8. False positives are rare.

Specifically, given that the data is not ASCII, the false positive rate for a 2-byte sequence is only 3.9% (1920/49152). For a 7-byte sequence, it's less than 1%. For a 12-byte sequence, it's less than 0.1%. For a 24-byte sequence, it's less than 1 in a million.

UTF-16

BOM is FE FF (for BE) or FF FE (for LE). Note that the UTF-16LE BOM is found at the start of the UTF-32LE BOM, so check UTF-32 first.

If you happen to have a file that consists mainly of ISO-8859-1 characters, having half of the file's bytes be 00 would also be a strong indicator of UTF-16.

Otherwise, the only reliable way to recognize UTF-16 without a BOM is to look for surrogate pairs (D[8-B]xx D[C-F]xx), but non-BMP characters are too rarely-used to make this approach practical.

XML

If your file starts with the bytes 3C 3F 78 6D 6C (i.e., the ASCII characters "<?xml"), then look for an encoding= declaration. If present, then use that encoding. If absent, then assume UTF-8, which is the default XML encoding.

If you need to support EBCDIC, also look for the equivalent sequence 4C 6F A7 94 93.

In general, if you have a file format that contains an encoding declaration, then look for that declaration rather than trying to guess the encoding.

None of the above

There are hundreds of other encodings, which require more effort to detect. I recommend trying Mozilla's charset detector or a .NET port of it.

A reasonable default

If you've ruled out the UTF encodings, and don't have an encoding declaration or statistical detection that points to a different encoding, assume ISO-8859-1 or the closely related Windows-1252. (Note that the latest HTML standard requires a “ISO-8859-1” declaration to be interpreted as Windows-1252.) Being Windows' default code page for English (and other popular languages like Spanish, Portuguese, German, and French), it's the most commonly encountered encoding other than UTF-8.

It's simple :

Let's imagine that you are trying to upload a file within js framework, ajax request or mobile application (Client side)

1. Firstly you send a data attribute that contains a base64 encoded string.
2. In the server side you have to decode it and save it in a local project folder.

Here how to do it using PHP

<?php 

$base64String = "kfezyufgzefhzefjizjfzfzefzefhuze"; // I put a static base64 string, you can implement you special code to retrieve the data received via the request.

$filePath = "/MyProject/public/uploads/img/test.png";

file_put_contents($filePath, base64_decode($base64String));

?>

For every PostScript printer, one part of its driver is an ASCII file called PostScript Printer Description (PPD). PPDs are used in the CUPS printing system on Linux and Mac OS X as well even for non-PostScript printers.

Every PPD MUST, according to the PPD specification written by Adobe, contain definitions of a *ImageableArea (that's a PPD keyword) for each and every media sizes it can handle. That value is given for example as *ImageableArea Folio/8,25x13: "12 12 583 923" for one printer in this office here, and *ImageableArea Folio/8,25x13: "0 0 595 935" for the one sitting in the next room.

These figures mean "Lower left corner is at (12|12), upper right corner is at (583|923)" (where these figures are measured in points; 72pt == 1inch). Can you see that the first printer does print with a margin of 1/6 inch? -- Can you also see that the next one can even print borderless?

What you need to know is this: Even if the printer can do very small margins physically, if the PPD *ImageableArea is set to a wider margin, the print data generated by the driver and sent to the printer will be clipped according to the PPD setting -- not by the printer itself.

These days more and more models appear on the market which can indeed print edge-to-edge. This is especially true for office laser printers. (Don't know about devices for the home use market.) Sometimes you have to enable that borderless mode with a separate switch in the driver settings, sometimes also on the device itself (front panel, or web interface).

Older models, for example HP's, define in their PPDs their margines quite generously, just to be on the supposedly "safe side". Very often HP used 1/3, 1/2 inch or more (like "24 24 588 768" for Letter format). I remember having hacked HP PPDs and tuned them down to "6 6 606 786" (1/12 inch) before the physical boundaries of the device kicked in and enforced a real clipping of the page image.

Now, PCL and other language printers are not that much different in their margin capabilities from PostScript models.

But of course, when it comes to printing of PDF docs, here you can nearly always choose "print to fit" or similarly named options. Even for a file that itself does not use any margins. That "fit" is what the PDF viewer reads from the driver, and the viewer then scales down the page to the *ImageableArea.

This should do it:

HTML

<input name="Name" value="Enter Your Name" onClick="blankDefault('Enter Your Name', this)">

JavaScript

function blankDefault(_text, _this) {
    if(_text == _this.value)
        _this.value = '';
}

There are better/less obtrusive ways though, but this will get the job done.

The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:

public static void main(String[] args) {
  int lines = 0;  

  // TODO - Need to get the filename to populate sFileName.  Could
  // come from the command line arguments.

   try {
       lines = LineCounter.countLines(sFileName);
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }

   if(lines > 0) {
     // Do rest of program.
   }
}

To do so without compiling the Regex first, use a lambda function - for example:

from re import match

values = ['123', '234', 'foobar']
filtered_values = list(filter(lambda v: match('^\d+$', v), values))

print(filtered_values)

Returns:

['123', '234']

filter() just takes a callable as it's first argument, and returns a list where that callable returned a 'truthy' value.

$newstr = substr_replace($oldstr, $str_to_insert, $pos, 0);

I will leave this here as a possible fix, worked for me at least and might help others. Pretty sure this would be a linux only fix.

I decided to not go with the pip install and go with the github version (option one on the installation guide).

Instead of placing the copied docker-compose directory into /usr/local/bin/docker-compose from the curl/github command, I went with /usr/bin/docker-compose which is the location of Docker itself and will force the program to run in root. So it works in root and sudo but now won't work without sudo so the opposite effect which is what you want to run it as a user anyways.

3 ideas for you to try:

1. Make sure that all your dlls are compiled against the same version of Common.
2. Check that you have project references in your solution instead of file references.
3. Use binding redirections in your web.config. (Originally linked version at wayback machine)

This implementation realizes your purpose, dynamically filling an array of strings with the content of the specified directory.

int exploreDirectory(const char *dirpath, char ***list, int *numItems) {
    struct dirent **direntList;
    int i;
    errno = 0;

    if ((*numItems = scandir(dirpath, &direntList, NULL, alphasort)) == -1)
        return errno;

    if (!((*list) = malloc(sizeof(char *) * (*numItems)))) {
        fprintf(stderr, "Error in list allocation for file list: dirpath=%s.\n", dirpath);
        exit(EXIT_FAILURE);
    }

    for (i = 0; i < *numItems; i++) {
        (*list)[i] = stringDuplication(direntList[i]->d_name);
    }

    for (i = 0; i < *numItems; i++) {
        free(direntList[i]);
    }

    free(direntList);

    return 0;
}

select username,
       account_status 
  from dba_users 
 where lock_date is not null;

This will actually give you the list of locked users.

For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.

For example, Before it was:

DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;

After putting DELIMITER it was like this:

DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;
$$
DELIMITER ;

The simplest solution is to add @Test annotated method to class where initialisation exception is present.

In our project we have main class with initial settings. I've added @Test method and exception has disappeared.

Try this

public class NetworkUtil {
    public static final int TYPE_WIFI = 1;
    public static final int TYPE_MOBILE = 2;
    public static final int TYPE_NOT_CONNECTED = 0;
    public static final int NETWORK_STATUS_NOT_CONNECTED = 0;
    public static final int NETWORK_STATUS_WIFI = 1;
    public static final int NETWORK_STATUS_MOBILE = 2;

    public static int getConnectivityStatus(Context context) {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        if (null != activeNetwork) {
            if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
                return TYPE_WIFI;

            if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
                return TYPE_MOBILE;
        } 
        return TYPE_NOT_CONNECTED;
    }

    public static int getConnectivityStatusString(Context context) {
        int conn = NetworkUtil.getConnectivityStatus(context);
        int status = 0;
        if (conn == NetworkUtil.TYPE_WIFI) {
            status = NETWORK_STATUS_WIFI;
        } else if (conn == NetworkUtil.TYPE_MOBILE) {
            status = NETWORK_STATUS_MOBILE;
        } else if (conn == NetworkUtil.TYPE_NOT_CONNECTED) {
            status = NETWORK_STATUS_NOT_CONNECTED;
        }
        return status;
    }
}

And for the BroadcastReceiver

public class NetworkChangeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {

        int status = NetworkUtil.getConnectivityStatusString(context);
        Log.e("Sulod sa network reciever", "Sulod sa network reciever");
        if ("android.net.conn.CONNECTIVITY_CHANGE".equals(intent.getAction())) {
            if (status == NetworkUtil.NETWORK_STATUS_NOT_CONNECTED) {
                new ForceExitPause(context).execute();
            } else {
                new ResumeForceExitPause(context).execute();
            }
       }
    }
}

Don't forget to put this into your AndroidManifest.xml

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 <uses-permission android:name="android.permission.INTERNET" />
 <receiver
        android:name="NetworkChangeReceiver"
        android:label="NetworkChangeReceiver" >
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
            <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
        </intent-filter>
    </receiver>

Hope this will help you Cheers!

It's probably a stylistic preference more than anything. I just checked PEP 8 and didn't see any mention of single versus double quotes.

I prefer single quotes because its only one keystroke instead of two. That is, I don't have to mash the shift key to make single quote.

No -- neither. Per the Go for C++ programmers docs,

Go does not support function overloading and does not support user defined operators.

I can't find an equally clear statement that optional parameters are unsupported, but they are not supported either.

For someone having the same problem -

import name 'path' from 'django.urls' 
(C:\Python38\lib\site-packages\django\urls\__init__.py)

You can also try installing django-urls by

pipenv install django-urls

Solution 1 : You can do like this :

List<car> result = GetSomeOtherList().Except(GetTheList()).ToList();

But in some cases may this solution not work. if it is not work you can use my second solution .

Solution 2 :

List<car> list1 = GetTheList();
List<car> list2 = GetSomeOtherList();

we pretend that list1 is your main list and list2 is your secondry list and you want to get items of list1 without items of list2.

 var result =  list1.Where(p => !list2.Any(x => x.ID == p.ID && x.property1 == p.property1)).ToList();

I am not really sure why, but as soon as I comment out the following method it works:

connectionDidFinishDownloading:destinationURL:

Furthermore, I don't think you need the methods from the NSUrlConnectionDownloadDelegate protocol, only those from NSURLConnectionDataDelegate, unless you want some download information.

New versions of JUnit contains the Categories runner: http://kentbeck.github.com/junit/doc/ReleaseNotes4.8.html

But releasing procedure of JUnit is not maven based, so maven users have to put it manually to their repositories.

append() creates a new array which can be the old array with the appended element.

I think it's more normal to use the proper method for adding an element:

a = numpy.append(a, a[0])

To get or set an attribute of an HTML element, you can use the element.attr() function in jQuery.

To get the href attribute, use the following code:

var a_href = $('selector').attr('href');

To set the href attribute, use the following code:

$('selector').attr('href','http://example.com');

In both cases, please use the appropriate selector. If you have set the class for the anchor element, use '.class-name' and if you have set the id for the anchor element, use '#element-id'.

The parts explained:

<: Starting character

\s*: It may have whitespaces before the tag name (ugly, but possible).

(\w+): tags can contain letters and numbers (h1). Well, \w also matches '_', but it does not hurt I guess. If curious, use ([a-zA-Z0-9]+) instead.

[^/>]*: Anything except > and / until closing >

And to the fellows, who underestimate regular expressions, saying they are only as powerful as regular languages:

aⁿbaⁿbaⁿ which is not regular and not even context free, can be matched with ^(a+)b\1b\1$

Backreferencing FTW!

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..

In numpy, index and dimension numbering starts with 0. So axis 0 means the 1st dimension. Also in numpy a dimension can have length (size) 0. The simplest case is:

In [435]: x = np.zeros((0,), int)
In [436]: x
Out[436]: array([], dtype=int32)
In [437]: x[0]
...
IndexError: index 0 is out of bounds for axis 0 with size 0

I also get it if x = np.zeros((0,5), int), a 2d array with 0 rows, and 5 columns.

So someplace in your code you are creating an array with a size 0 first axis.

When asking about errors, it is expected that you tell us where the error occurs.

Also when debugging problems like this, the first thing you should do is print the shape (and maybe the dtype) of the suspected variables.

Applied to pandas

• The same error can occur for those using pandas, when sending a Series or DataFrame to a numpy.array, as with the following:
  • pandas.Series.values or pandas.Series.to_numpy() or pandas.Series.array
  • pandas.DataFrame.values or pandas.DataFrame.to_numpy()

Resolving the error:

1. Use a try-except block
2. Verify the size of the array is not 0
   • if x.size != 0:

Executing the command: Devenv.exe /ResetSettings like :

S3 is not used for real time development but if you really want to test your freshly deployed website use

http://yourdomain.com/index.html?v=2

Adding a version parameter in the end will stop using the cached version of the file and the browser will get a fresh copy of the file from the server bucket

This can be done as follows :

select CONVERT(VARCHAR(10), GETDATE(), 103) + ' '  + convert(VARCHAR(8), GETDATE(), 14)

Hope it helps

For Python 3, use the following:

import urllib.parse

A few years late but hopefully this will help someone else...

1) First make sure the EC2 instance has a public IP. If has a Public DNS or Public IP address (circled below) then you should be good. This will be the address you ping.

2) Next make sure the Amazon network rules allow Echo Requests. Go to the Security Group for the EC2.

• right click, select inbound rules
• A: select Add Rule
• B: Select Custom ICMP Rule - IPv4
• C: Select Echo Request
• D: Select either Anywhere or My IP
• E: Select Save

3) Next, Windows firewall blocks inbound Echo requests by default. Allow Echo requests by creating a windows firewall exception...

• Go to Start and type Windows Firewall with Advanced Security
• Select inbound rules

4) Done! Hopefully you should now be able to ping your server.

By design, domain names must have at least two dots; otherwise the browser will consider them invalid. (See reference on http://curl.haxx.se/rfc/cookie_spec.html)

When working on localhost, the cookie domain must be omitted entirely. You should not set it to "" or NULL or FALSE instead of "localhost". It is not enough.

For PHP, see comments on http://php.net/manual/en/function.setcookie.php#73107.

If working with the Java Servlet API, don't call the cookie.setDomain("...") method at all.

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

Object[] possibleValues = enumValue.getDeclaringClass().getEnumConstants();

Take any web application running in any servlet container (Tomcat, Jetty, Glassfish, whatever...). Redeploy the app 10 or 20 times in a row (it may be enough to simply touch the WAR in the server's autodeploy directory.

Unless anybody has actually tested this, chances are high that you'll get an OutOfMemoryError after a couple of redeployments, because the application did not take care to clean up after itself. You may even find a bug in your server with this test.

The problem is, the lifetime of the container is longer than the lifetime of your application. You have to make sure that all references the container might have to objects or classes of your application can be garbage collected.

If there is just one reference surviving the undeployment of your web app, the corresponding classloader and by consequence all classes of your web app cannot be garbage collected.

Threads started by your application, ThreadLocal variables, logging appenders are some of the usual suspects to cause classloader leaks.

I just ran into this question and, while it is old, I figured I'd add an answer for the archives. The OP asked about for loops, but their goal was to gather a random sample of rows from the table. For that task, Postgres 9.5+ offers the TABLESAMPLE clause on WHERE. Here's a good rundown:

https://www.2ndquadrant.com/en/blog/tablesample-in-postgresql-9-5-2/

I tend to use Bernoulli as it's row-based rather than page-based, but the original question is about a specific row count. For that, there's a built-in extension:

https://www.postgresql.org/docs/current/tsm-system-rows.html

CREATE EXTENSION tsm_system_rows;

Then you can grab whatever number of rows you want:

select * from playtime tablesample system_rows (15);

Just subtract a number:

> as.Date("2009-10-01")
[1] "2009-10-01"
> as.Date("2009-10-01")-5
[1] "2009-09-26"

Since the Date class only has days, you can just do basic arithmetic on it.

If you want to use POSIXlt for some reason, then you can use it's slots:

> a <- as.POSIXlt("2009-10-04")
> names(unclass(as.POSIXlt("2009-10-04")))
[1] "sec"   "min"   "hour"  "mday"  "mon"   "year"  "wday"  "yday"  "isdst"
> a$mday <- a$mday - 6
> a
[1] "2009-09-28 EDT"

You can find dimension of an image on the page using something like

document.getElementById('someImage').width

file size, however, you will have to use something server-side

As the question is asked simply use @Min(1) instead of @size on integer fields and it will work.

You can set content view (or design) of an activity. For example you can do it like this too :

public void onCreate(Bundle savedinstanceState) {
    super.onCreate(savedinstanceState);

    Button testButon = new Button(this);

    setContentView(testButon);   
}

GCC can't do that but GDB (a debugger) sure can. Compile you program using the -g switch, like this:

gcc program.c -g

Then use gdb:

$ gdb ./a.out
(gdb) run
<segfault happens here>
(gdb) backtrace
<offending code is shown here>

Here is a nice tutorial to get you started with GDB.

Where the segfault occurs is generally only a clue as to where "the mistake which causes" it is in the code. The given location is not necessarily where the problem resides.

There does not seem to be any answer which addresses the very common beginner problem of failing to install the required library in the first place.

On Debianish platforms, if libfoo is missing, you can frequently install it with something like

apt-get install libfoo-dev

The -dev version of the package is required for development work, even trivial development work such as compiling source code to link to the library.

The package name will sometimes require some decorations (libfoo0-dev? foo-dev without the lib prefix? etc), or you can simply use your distro's package search to find out precisely which packages provide a particular file.

(If there is more than one, you will need to find out what their differences are. Picking the coolest or the most popular is a common shortcut, but not an acceptable procedure for any serious development work.)

For other architectures (most notably RPM) similar procedures apply, though the details will be different.

When you do valueForKey: you need to give it an NSString, whereas objectForKey: can take any NSObject subclass as a key. This is because for Key-Value Coding, the keys are always strings.

In fact, the documentation states that even when you give valueForKey: an NSString, it will invoke objectForKey: anyway unless the string starts with an @, in which case it invokes [super valueForKey:], which may call valueForUndefinedKey: which may raise an exception.

Try to check this free an open source alternative https://www.nuget.org/packages/AIM It is free to use and open source and uses the exact same way that System.Net.Mail is using To send email to implicit ssl ports you can use following code

public static void SendMail()
{    
    var mailMessage = new MimeMailMessage();
    mailMessage.Subject = "test mail";
    mailMessage.Body = "hi dude!";
    mailMessage.Sender = new MimeMailAddress("[email protected]", "your name");
    mailMessage.To.Add(new MimeMailAddress("[email protected]", "your friendd's name")); 
// You can add CC and BCC list using the same way
    mailMessage.Attachments.Add(new MimeAttachment("your file address"));

//Mail Sender (Smtp Client)

    var emailer = new SmtpSocketClient();
    emailer.Host = "your mail server address";
    emailer.Port = 465;
    emailer.SslType = SslMode.Ssl;
    emailer.User = "mail sever user name";
    emailer.Password = "mail sever password" ;
    emailer.AuthenticationMode = AuthenticationType.Base64;
    // The authentication types depends on your server, it can be plain, base 64 or none. 
//if you do not need user name and password means you are using default credentials 
// In this case, your authentication type is none            
    emailer.MailMessage = mailMessage;
    emailer.OnMailSent += new SendCompletedEventHandler(OnMailSent);
    emailer.SendMessageAsync();
}

// A simple call back function:
private void OnMailSent(object sender, AsyncCompletedEventArgs asynccompletedeventargs)
{
if (e.UserState!=null)
    Console.Out.WriteLine(e.UserState.ToString());
if (e.Error != null)
{
    MessageBox.Show(e.Error.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
else if (!e.Cancelled)
{
    MessageBox.Show("Send successfull!", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
} 

You can flip a value like so:

myVal = !myVal;

so your code would shorten down to:

switch(wParam) {
    case VK_F11:
    flipVal = !flipVal;
    break;

    case VK_F12:
    otherVal = !otherVal;
    break;

    default:
    break;
}

The easiest way without fiddling with command line:

1. launch Xcode once.
2. run ios simulator
3. drag the ios simulator icon to dock it.

Next time you want to use it, just click on the ios simulator icon in the dock.

I run cntlm localy, configured with NTLMv2 password hashes to authenticate with the corporate proxy, and use

export MAVEN_OPTS="-DproxyHost=127.0.0.1 -DproxyPort=3128"

to use that proxy from maven. Of course the proxy you use should support cntlm/NTLMv2.

I ran into this problem myself and realized that it was because of a side-effect of a Filter that I created which was filtering all requests on the appliation. As soon as I modified the filter to pick only certain requests, this problem did not occur. It maybe good to check for such filters in your application and see how they behave.

Actually the orderBy filter can take as a parameter not only a string but also a function. From the orderBy documentation: https://docs.angularjs.org/api/ng/filter/orderBy):

function: Getter function. The result of this function will be sorted using the <, =, > operator.

So, you could write your own function. For example, if you would like to compare cards based on a sum of opt1 and opt2 (I'm making this up, the point is that you can have any arbitrary function) you would write in your controller:

$scope.myValueFunction = function(card) {
   return card.values.opt1 + card.values.opt2;
};

and then, in your template:

ng-repeat="card in cards | orderBy:myValueFunction"

Here is the working jsFiddle

The other thing worth noting is that orderBy is just one example of AngularJS filters so if you need a very specific ordering behaviour you could write your own filter (although orderBy should be enough for most uses cases).

Use btoa() for encode and atob() for decode

text_val:any="your encoding text";

Encoded Text: console.log(btoa(this.text_val)); //eW91ciBlbmNvZGluZyB0ZXh0

Decoded Text: console.log(atob("eW91ciBlbmNvZGluZyB0ZXh0")); //your encoding text

Here is a solution using an overlay that inhibits along with material design spinner that you configure one time in your app and you can call it from anywhere.

Should do it.

set encoding=utf-8  " The encoding displayed.
set fileencoding=utf-8  " The encoding written to file.

You may as well set both in your ~/.vimrc if you always want to work with utf-8.

Collection is the root interface to the java Collections hierarchy. List is one sub interface which defines an ordered Collection, other sub interfaces are Queue which typically will store elements ready for processing (e.g. stack).

The following diagram demonstrates the relationship between the different java collection types:

I use the package enumitem. You may then set such margins when you declare your lists (enumerate, description, itemize):

\begin{itemize}[leftmargin=0cm]
    \item Foo
    \item Bar
\end{itemize}

Naturally, the package provides lots of other nice customizations for lists (use 'label=' to change the bullet, use 'itemsep=' to change the spacing between items, etc...)

Based on the very helpful answer by joran I was able to come up with this solution for a stable color scale for a boolean factor (TRUE, FALSE).

boolColors <- as.character(c("TRUE"="#5aae61", "FALSE"="#7b3294"))
boolScale <- scale_colour_manual(name="myboolean", values=boolColors)

ggplot(myDataFrame, aes(date, duration)) + 
  geom_point(aes(colour = myboolean)) +
  boolScale

Since ColorBrewer isn't very helpful with binary color scales, the two needed colors are defined manually.

Here myboolean is the name of the column in myDataFrame holding the TRUE/FALSE factor. date and duration are the column names to be mapped to the x and y axis of the plot in this example.

From your Fragment: ( get Toolbar from fragment?)

// get toolbar
((MainAcivity)this.getActivity()).getToolbar();  // getToolbar will be method in Activity that returns Toolbar!!  don't use getSupportActionBar for getting toolbar!!
// get action bar
this.getActivity().getSupportActionBar();

this is very helpful when you are using spinner in Toolbar and call the spinner or custom views in Toolbar from a fragment!

From your Activity:

// get toolbar
this.getToolbar();
// get Action Bar
this.getSupportActionBar();

SyntaxHighlighter is a fully functional self-contained code syntax highlighter developed in JavaScript. To get an idea of what SyntaxHighlighter is capable of, have a look at the demo page.

To remove the special characters, try

var name = name.replace(/[!@#$%^&*]/g, "");

String current = elements[i];
if (i != elements.length - 1) {
   String next = elements[i+1];
}

This makes sure you don't get an ArrayIndexOutOfBoundsException for the last element (there is no 'next' there). The other option is to iterate to i < elements.length - 1. It depends on your requirements.

I suspect something is not right when you are saving to the db. Do i understand your steps as:

1. populate and bind
2. user selects and item, hit and save.. then you save in the db
3. now if you select another item it won't select?

got more code, especially when saving? where in your code are initializing and populating the bindinglist

You can get the managed bean by passing the name:

public static Object getBean(String beanName){
    Object bean = null;
    FacesContext fc = FacesContext.getCurrentInstance();
    if(fc!=null){
         ELContext elContext = fc.getELContext();
         bean = elContext.getELResolver().getValue(elContext, null, beanName);
    }

    return bean;
}

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Maybe a bit late to post an answer for this, but I found some of the above solutions a bit cumbersome.

I tried simple string replacement in sed and it worked:

sed 's/CLIENTSCRIPT="foo"/&\nCLIENTSCRIPT2="hello"/' file

& sign reflects the matched string, and then you add \n and the new line.

As mentioned, if you want to do it in-place:

sed -i 's/CLIENTSCRIPT="foo"/&\nCLIENTSCRIPT2="hello"/' file

Another thing. You can match using an expression:

sed -i 's/CLIENTSCRIPT=.*/&\nCLIENTSCRIPT2="hello"/' file

Hope this helps someone

This is better to remove NodeJS and its modules manually because installation leaves a lot of files, links and modules behind and later it create problems while we reconfigure another version of NodeJS and its modules. Run the following commands.

sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp /opt/local/bin/node opt/local/include/node /opt/local/lib/node_modules 


sudo rm -rf /usr/local/lib/node*     
sudo rm -rf /usr/local/include/node*         
sudo rm -rf /usr/local/bin/node*

and this done.

A step by step guide with commands is at http://amcositsupport.blogspot.in/2016/07/to-completely-uninstall-node-js-from.html

This helped me resolve my problem.

For the SQL Server 2019 (Express Edition) installation, I did the following:

1. Open SQL Server Installation Center
2. Click on Installation
3. Click on New SQL Server stand-alone installation or add features to an existing installation
4. Browse to C:\SQL2019\Express_ENU and click OK

you can try to export as "Runnable jar" in eclipse. I have also problems, when i export as "jar", but i have never problems when i export as "Runnable jar".

After trying some ways to load the file with no success, I remembered I could use FileInputStream, which worked perfectly.

InputStream is = new FileInputStream("file.txt");

This is another way to read a file into an InputStream, it reads the file from the currently running folder.

You can't make modification to the collection being iterated within the ForEach block.

A quick fix is to iterate over a copy of the collection. An easy way to make this copy is through the ArrayList constructor. The DataRowView objects in the copied collection will refer to, and be able to modify, the same underlying data as your code.

What

• A settings file for the server
• Cannot be accessed by end-user
• There is no need to reboot the server, changes work immediately
• It might serve as a bridge between your code and server

We can do

• URL rewriting
• Custom error pages
• Caching
• Redirections
• Blocking ip's

Every SQL batch has to fit in the Batch Size Limit: 65,536 * Network Packet Size.

Other than that, your query is limited by runtime conditions. It will usually run out of stack size because x IN (a,b,c) is nothing but x=a OR x=b OR x=c which creates an expression tree similar to x=a OR (x=b OR (x=c)), so it gets very deep with a large number of OR. SQL 7 would hit a SO at about 10k values in the IN, but nowdays stacks are much deeper (because of x64), so it can go pretty deep.

Update

You already found Erland's article on the topic of passing lists/arrays to SQL Server. With SQL 2008 you also have Table Valued Parameters which allow you to pass an entire DataTable as a single table type parameter and join on it.

XML and XPath is another viable solution:

SELECT ...
FROM Table
JOIN (
   SELECT x.value(N'.',N'uniqueidentifier') as guid
   FROM @values.nodes(N'/guids/guid') t(x)) as guids
 ON Table.guid = guids.guid;

In case you'd like to paste windows path from other source (say, File Explorer) - you can do so via input() call in python console:

>>> input()
D:\EP\stuff\1111\this_is_a_long_path\you_dont_want\to_type\or_edit_by_hand
'D:\\EP\\stuff\\1111\\this_is_a_long_path\\you_dont_want\\to_type\\or_edit_by_hand'

Then just copy the result

My solution handles quotes, overriding field and string separators, etc. It is short and sweet.

    public static string[] CSVRowToStringArray(string r, char fieldSep = ',', char stringSep = '\"')
    {
        bool bolQuote = false;
        StringBuilder bld = new StringBuilder();
        List<string> retAry = new List<string>();

        foreach (char c in r.ToCharArray())
            if ((c == fieldSep && !bolQuote))
            {
                retAry.Add(bld.ToString());
                bld.Clear();
            }
            else
                if (c == stringSep)
                    bolQuote = !bolQuote;
                else
                    bld.Append(c);

        return retAry.ToArray();
    }

There are two ways to Run Visual Studio as Administrator:

1. Only 1 time: For this go to startup search bar, search for Visual studio 2017 or what ever version you have, then Right click on VS and Run as Administrator.

2. Permanent or Always: For this go to startup search bar, search for visual studio, right click to it and go to properties. In the properties click on advanced button and check the Run as Administrator check box and then click on ok.

Let's polyfill:

if(!AbortController){
  class AbortController {
    constructor() {
      this.aborted = false;
      this.signal = this.signal.bind(this);
    }
    signal(abortFn, scope) {
      if (this.aborted) {
        abortFn.apply(scope, { name: 'AbortError' });
        this.aborted = false;
      } else {
        this.abortFn = abortFn.bind(scope);
      }
    }
    abort() {
      if (this.abortFn) {
        this.abortFn({ reason: 'canceled' });
        this.aborted = false;
      } else {
        this.aborted = true;
      }
    }
  }

  const originalFetch = window.fetch;

  const customFetch = (url, options) => {
    const { signal } = options || {};

    return new Promise((resolve, reject) => {
      if (signal) {
        signal(reject, this);
      }
      originalFetch(url, options)
        .then(resolve)
        .catch(reject);
    });
  };

  window.fetch = customFetch;
}

Please have in mind that the code is not tested! Let me know if you have tested it and something didn't work. It may give you warnings that you try to overwrite the 'fetch' function from the JavaScript official library.

How about something like:

\documentclass{article}

\usepackage{amssymb,amsmath}

\begin{document}

\begin{equation}\label{A_Label}
  \begin{split}
    w^T x_i + b \geqslant 1-\xi_i \text{ if } y_i &= 1, \\
    w^T x_i + b \leqslant -1+\xi_i \text{ if } y_i &= -1
  \end{split}
\end{equation}

\end{document}

which produces:

lockless Copy and Write approach works great if you're not dealing with too many items. Here's a class I wrote:

public class CopyAndWriteList<T>
{
    public static List<T> Clear(List<T> list)
    {
        var a = new List<T>(list);
        a.Clear();
        return a;
    }

    public static List<T> Add(List<T> list, T item)
    {
        var a = new List<T>(list);
        a.Add(item);
        return a;
    }

    public static List<T> RemoveAt(List<T> list, int index)
    {
        var a = new List<T>(list);
        a.RemoveAt(index);
        return a;
    }

    public static List<T> Remove(List<T> list, T item)
    {
        var a = new List<T>(list);
        a.Remove(item);
        return a;
    }

}

example usage: orders_BUY = CopyAndWriteList.Clear(orders_BUY);

res.send is used to send the response to the client where res.end is used to end the response you are sending.

res.send automatically call res.end So you don't have to call or mention it after res.send

I bumped into this problem on a cPanel CentOS 6 linux machine. The solution for me was to symlink the cPanel git to /usr/local/bin/git

ln -s /usr/local/cpanel/3rdparty/bin/git /usr/local/bin/git

This is similar to your original approach, and will use less space than unutbu's answer, but I suspect it will be slower.

>>> import numpy as np
>>> p = np.array([[1.5, 0], [1.4,1.5], [1.6, 0], [1.7, 1.8]])
>>> p
array([[ 1.5,  0. ],
       [ 1.4,  1.5],
       [ 1.6,  0. ],
       [ 1.7,  1.8]])
>>> nz = (p == 0).sum(1)
>>> q = p[nz == 0, :]
>>> q
array([[ 1.4,  1.5],
       [ 1.7,  1.8]])

By the way, your line p.delete() doesn't work for me - ndarrays don't have a .delete attribute.

You don't need awk for that. Using read in Bash shell should be enough, e.g.

some_command | while read c1 c2; do echo $c2; done

or:

while read c1 c2; do echo $c2; done < in.txt

I used the following code to get the last character of a string.

    substr(output, nchar(stringOfInterest), nchar(stringOfInterest))

You can play with the nchar(stringOfInterest) to figure out how to get last few characters.

Generally and simply it works like this:

<script>_x000D_
            $(document).ready(function () {_x000D_
                $('i').click(function () {_x000D_
                    $(this).toggleClass('fa-plus-square fa-minus-square');_x000D_
                });_x000D_
            });_x000D_
</script>

I just wanted to note here that Chrome also ignores page-break-* css settings in divs that have been floated.

I suspect there is a sound justification for this somewhere in the css spec, but I figured noting it might help someone someday ;-)

Just another note: IE7 can't acknowledge page break settings without an explicit height on the previous block element:

http://social.msdn.microsoft.com/forums/en-US/iewebdevelopment/thread/fe523ec6-2f01-41df-a31d-9ba93f21787b/

It must be an array if you want to iterate over it. You're very likely missing [ and ].

var x = [{
    "id": "1",
        "msg": "hi",
        "tid": "2013-05-05 23:35",
        "fromWho": "[email protected]"
}, {
    "id": "2",
        "msg": "there",
        "tid": "2013-05-05 23:45",
        "fromWho": "[email protected]"
}];

var $output = $('#output');
for(var i = 0; i < x.length; i++) {
    console.log(x[i].id);
}

Have a look at Access Modifiers (C# Programming Guide)

Class and Struct Accessibility

Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.

Struct members, including nested classes and structs, can be declared as public, internal, or private. Class members, including nested classes and structs, can be public, protected internal, protected, internal, private protected or private. The access level for class members and struct members, including nested classes and structs, is private by default. Private nested types are not accessible from outside the containing type.

Derived classes cannot have greater accessibility than their base types. In other words, you cannot have a public class B that derives from an internal class A. If this were allowed, it would have the effect of making A public, because all protected or internal members of A are accessible from the derived class.

You can enable specific other assemblies to access your internal types by using the InternalsVisibleToAttribute. For more information, see Friend Assemblies.

Class and Struct Member Accessibility

Class members (including nested classes and structs) can be declared with any of the six types of access. Struct members cannot be declared as protected because structs do not support inheritance.

Normally, the accessibility of a member is not greater than the accessibility of the type that contains it. However, a public member of an internal class might be accessible from outside the assembly if the member implements interface methods or overrides virtual methods that are defined in a public base class.

The type of any member that is a field, property, or event must be at least as accessible as the member itself. Similarly, the return type and the parameter types of any member that is a method, indexer, or delegate must be at least as accessible as the member itself. For example, you cannot have a public method M that returns a class C unless C is also public. Likewise, you cannot have a protected property of type A if A is declared as private.

User-defined operators must always be declared as public and static. For more information, see Operator overloading.

Finalizers cannot have accessibility modifiers.

Other Types

Interfaces declared directly within a namespace can be declared as public or internal and, just like classes and structs, interfaces default to internal access. Interface members are always public because the purpose of an interface is to enable other types to access a class or struct. No access modifiers can be applied to interface members.

Enumeration members are always public, and no access modifiers can be applied.

Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.

after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:

  <Directory "c:/wamp/www"><!-- maybe other url-->

    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:

     Order Deny,Allow
    Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
</Directory>

3- Change to: Deny from none
like this:

4- Restart Apache
Don't forget restart Apache or all servises!!!

Parameters can be set on the fly also.

Please see @jlareau answer here: https://stackoverflow.com/questions/11534710/angularjs-how-to-use-routeparams-in-generating-the-templateurl

You can use a function to generate the template string:

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

app.config(
    function($routeProvider) {
        $routeProvider.
            when('/', {templateUrl:'/home'}).
            when('/users/:user_id', 
                {   
                    controller:UserView, 
                    templateUrl: function(params){ return '/users/view/' + params.user_id;   }
                }
            ).
            otherwise({redirectTo:'/'});
    }
);

Jenkins has a link to their REST API in the bottom right of each page. This link appears on every page of Jenkins and points you to an API output for the exact page you are browsing. That should provide some understanding into how to build the API URls.

You can additionally use some wrapper, like I do, in Python, using http://jenkinsapi.readthedocs.io/en/latest/

Here is their website: https://wiki.jenkins-ci.org/display/JENKINS/Remote+access+API

  return Object.entries(obj).reduce((collector, [key, val]) => {_x000D_
    const newKeys = [ ...collector, prefix ? `${prefix}.${key}` : key ]_x000D_
    if (Object.prototype.toString.call(val) === '[object Object]') {_x000D_
      const newPrefix = prefix ? `${prefix}.${key}` : key_x000D_
      const otherKeys = getObjectKeys(val, newPrefix)_x000D_
      return [ ...newKeys, ...otherKeys ]_x000D_
    }_x000D_
    return newKeys_x000D_
  }, [])_x000D_
}_x000D_
_x000D_
console.log(getObjectKeys({a: 1, b: 2, c: { d: 3, e: { f: 4 }}}))

Since it takes 2 mins to respond, you can increase the timeout to 3 mins by adding the below code

scGetruntotals.CommandTimeout = 180;

Note : the parameter value is in seconds.

No need to use jQuery for this:

var foo = document.getElementById('yourSelect');
if (foo)
{
   if (foo.selectedIndex != null)
   {
       foo.selectedIndex = 0;
   } 
}

I won't quote the entire page but the whole manual on optimisation is available here: http://gcc.gnu.org/onlinedocs/gcc-4.4.3/gcc/Optimize-Options.html#Optimize-Options

From the sounds of it you want at least -O0, the default, and:

-fmudflap -fmudflapth -fmudflapir

For front-ends that support it (C and C++), instrument all risky pointer/array dereferencing operations, some standard library string/heap functions, and some other associated constructs with range/validity tests. Modules so instrumented should be immune to buffer overflows, invalid heap use, and some other classes of C/C++ programming errors. The instrumentation relies on a separate runtime library (libmudflap), which will be linked into a program if -fmudflap is given at link time. Run-time behavior of the instrumented program is controlled by the MUDFLAP_OPTIONS environment variable. See env MUDFLAP_OPTIONS=-help a.out for its options.

.subscribe is not an Angular2 thing.

It's a method that comes from rxjs library which Angular is using internally.

If you can imagine yourself subscribing to a newsletter, every time there is a new newsletter, they will send it to your home (the method inside subscribe gets called).

That's what happens when you subscribing to a source of magazines ( which is called an Observable in rxjs library)

All the AJAX calls in Angular are using rxjs internally and in order to use any of them, you've got to use the method name, e.g get, and then call subscribe on it, because get returns and Observable.

Also, when writing this code <button (click)="doSomething()">, Angular is using Observables internally and subscribes you to that source of event, which in this case is a click event.

Back to our analogy of Observables and newsletter stores, after you've subscribed, as soon as and as long as there is a new magazine, they'll send it to you unless you go and unsubscribe from them for which you have to remember the subscription number or id, which in rxjs case it would be like :

 let subscription = magazineStore.getMagazines().subscribe(
   (newMagazine)=>{

         console.log('newMagazine',newMagazine);

    }); 

And when you don't want to get the magazines anymore:

   subscription.unsubscribe();

Also, the same goes for

 this.route.paramMap

which is returning an Observable and then you're subscribing to it.

My personal view is rxjs was one of the greatest things that were brought to JavaScript world and it's even better in Angular.

There are 150~ rxjs methods ( very similar to lodash methods) and the one that you're using is called switchMap

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

You can do this with plain js by using

1. location.host , same as document.location.hostname
2. document.domain Not recommended

Very late but what solved the problem for me was that my test method names all started with captial letters: "public void Test". Making the t lower case worked.

Besides using std::find (from algorithm), you can also use std::find_if (which is, IMO, better than std::find), or other find algorithm from this list

#include <list>
#include <algorithm>
#include <iostream>

int main()
{
    std::list<int> myList{ 5, 19, 34, 3, 33 };
    

    auto it = std::find_if( std::begin( myList ),
                            std::end( myList ),
                            [&]( const int v ){ return 0 == ( v % 17 ); } );
        
    if ( myList.end() == it )
    {
        std::cout << "item not found" << std::endl;
    }
    else
    {
        const int pos = std::distance( myList.begin(), it ) + 1;
        std::cout << "item divisible by 17 found at position " << pos << std::endl;
    }
}

For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.

Try something like

convert -density 300 image.eps -resize 1024x1024 image.jpg

Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.

The order of the arguments matters! The -density X argument needs to go before image.eps because you want to affect the resolution that the input file is rendered at.

This is not super obvious in the manpage for convert, but is hinted at:

SYNOPSIS

convert [input-option] input-file [output-option] output-file

public boolean compareMap(Map<String, String> map1, Map<String, String> map2) {

    if (map1 == null || map2 == null)
        return false;

    for (String ch1 : map1.keySet()) {
        if (!map1.get(ch1).equalsIgnoreCase(map2.get(ch1)))
            return false;

    }
    for (String ch2 : map2.keySet()) {
        if (!map2.get(ch2).equalsIgnoreCase(map1.get(ch2)))
            return false;

    }

    return true;
}

I have other worked solution here,

1. Quit Xcode
2. Open Xcode and clean project
3. Build Pods project first
4. Build Project

As explained in the documentation, by using an @RequestParam annotation:

public @ResponseBody String byParameter(@RequestParam("foo") String foo) {
    return "Mapped by path + method + presence of query parameter! (MappingController) - foo = "
           + foo;
}

As long as your Fragment creates a View, you can use the IBinder (window token) from that view after it has been attached. For example, you can override onActivityCreated in your Fragment:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    final InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
}

Try this

subset(data, !(v1 %in% c("b","d","e")))

UPDATE

In Android Studio Version 3.5 and Above

Now Instant Run is removed, It has "Apply Changes". See official blog for more about the change.

we removed Instant Run and re-architectured and implemented from the ground-up a more practical approach in Android Studio 3.5 called Apply Changes.Apply Changes uses platform-specific APIs from Android Oreo and higher to ensure reliable and consistent behavior; unlike Instant Run, Apply Changes does not modify your APK. To support the changes, we re-architected the entire deployment pipeline to improve deployment speed, and also tweaked the run and deployment toolbar buttons for a more streamlined experience.

Now, As per stable available version 3.0 of Android studio,

If you need to turn off Instant Run, go to

File ? Settings ? Build, Execution, Deployment ? Instant Run and uncheck Enable Instant Run.

Update maven version to 3.6.3 and run

mvn -Dhttps.protocols=TLSv1.2 install

it worked on centos 6.9

to get/set the actual selectedIndex property of the select element use:

$("#select-id").prop("selectedIndex");

$("#select-id").prop("selectedIndex",1);

If you're in the middle of a commit (i.e. in your editor already), you can cancel it by deleting all lines above the first #. That will abort the commit.

So you can delete all lines so that the commit message is empty, then save the file:

You'll then get a message that says Aborting commit due to empty commit message..

EDIT:

You can also delete all the lines and the result will be exactly the same.

To delete all lines in vim (if that is your default editor), once you're in the editor, type gg to go to the first line, then dG to delete all lines. Finally, write and quit the file with wq and your commit will be aborted.

The standard approach is to use sprintf(buffer, "%lu", value); to write a string rep of value to buffer. However, overflow is a potential problem, as sprintf will happily (and unknowingly) write over the end of your buffer.

This is actually a big weakness of sprintf, partially fixed in C++ by using streams rather than buffers. The usual "answer" is to allocate a very generous buffer unlikely to overflow, let sprintf output to that, and then use strlen to determine the actual string length produced, calloc a buffer of (that size + 1) and copy the string to that.

This site discusses this and related problems at some length.

Some libraries offer snprintf as an alternative which lets you specify a maximum buffer size.

Same thing but in ANSI way

SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME IN ( SELECT TABLE_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME = 'CreateDate' )

You can assign int to char directly.

int a = 65;
char c = a;
printf("%c", c);

In fact this will also work.

printf("%c", a);  // assuming a is in valid range

Use this snippet:

@echo off
echo something
echo.
echo press enter to exit
pause >nul
exit

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

Ctrl+Shift+F formats the selected line(s) or the whole source code if you haven't selected any line(s) as per the format specified in your Eclipse, while Ctrl+I gives proper indent to the selected line(s) or the current line if you haven't selected any line(s). try this. or more precisely

The Ant editor that ships with Eclipse can be used to reformat

XML/XHTML/HTML code (with a few configuration options in Window > Preferences > Ant > Editor).

You can right-click a file then

Open With... > Other... > Internal Editors > Ant Editor

Or add a file association between .html (or .xhtml) and that editor with

Window > Preferences > General > Editors > File Associations

Once open in the editor, hit ESC then CTRL-F to reformat.

Old question, but I found this useful. Turns out, there's also a specialized class for a Dictionary using a string for both the key and the value:

private static readonly StringDictionary SegmentSyntaxErrorCodes = new StringDictionary
{
    { "1", "Unrecognized segment ID" },
    { "2", "Unexpected segment" }
};

Edit: Per Chris's comment below, using Dictionary<string, string> over StringDictionary is generally preferred but will depend on your situation. If you're dealing with an older code base, you might be limited to the StringDictionary. Also, note that the following line:

myDict["foo"]

will return null if myDict is a StringDictionary, but an exception will be thrown in case of Dictionary<string, string>. See the SO post he mentioned for more information, which is the source of this edit.

You have to check Maven version:

mvn -version

You will find the Java version which Maven uses for compilation. You may need to reset JAVA_HOME if needed.

A very simple way if your code is in Python, where I didn't have to install a Python package, is the following:

\documentclass[11pt]{article}  
\usepackage{pythonhighlight}

\begin{document}

The following is some Python code

\begin{python}
# A comment
x = [5, 7, 10]
y = 0

for num in x:
    y += num
    
print(y)
\end{python}

\end{document}

which looks like:

Unfortunately, this only works for Python.

Well you just need to use document.getElementById('hello').setAttribute('class', 'someclass');.

Also innerHTML can lead to unexpected results! Consider the following;

var myParag = document.createElement('p');

if(under certain age)
{
    myParag.text="Good Bye";
    createCookie('age', 'not13', 0);
    return false;
{
else
{
    myParag.text="Hello";
    return true;
}

document.getElementById('hello').appendChild(myParag);

Perhaps a little off topic, just be informed that these kind of messages can also be seen when you are debugging your code with a breakpoint inside an async function like setTimeout like below:

[Violation] 'setTimeout' handler took 43129ms

That number (43129ms) depends on how long you stop in your async function

   /* worked for me  */
     <div id="divid"> </div>
     <script type="text/javascript">
         var hold = document.getElementById("divid");
         var checkbox = document.createElement('input');
         checkbox.type = "checkbox";
         checkbox.name = "chkbox1";
         checkbox.id = "cbid";
         var label = document.createElement('label');
         var tn = document.createTextNode("Not A RoBot");
         label.htmlFor="cbid";
         label.appendChild(tn); 
         hold.appendChild(label);
         hold.appendChild(checkbox);
      </script>  

Try to use "sudo" with the command you are running.

I would like to add to mentioned in the other answers the difference between volatile, Interlocked, and lock:

The volatile keyword can be applied to fields of these types:

• Reference types.
• Pointer types (in an unsafe context). Note that although the pointer itself can be volatile, the object that it points to cannot. In other words, you cannot declare a "pointer" to be "volatile".
• Simple types such as sbyte, byte, short, ushort, int, uint, char, float, and bool.
• An enum type with one of the following base types: byte, sbyte, short, ushort, int, or uint.
• Generic type parameters known to be reference types.
• IntPtr and UIntPtr.

Other types, including double and long, cannot be marked "volatile" because reads and writes to fields of those types cannot be guaranteed to be atomic. To protect multi-threaded access to those types of fields, use the Interlocked class members or protect access using the lock statement.

The difficulty I've had with the other solutions is they rely on restarting your application if you want to get the indexes working again.

For my needs (i.e. being able to run a unit test the nukes all collections, then recreates them along with their indexes), I ended up implementing this solution:

This relies on the underscore.js and async.js libraries to assemble the indexes in parellel, it could be unwound if you're against that library but I leave that as an exerciser for the developer.

mongoose.connection.db.executeDbCommand( {dropDatabase:1}, function(err, result) {
  var mongoPath = mongoose.connections[0].host + ':' + mongoose.connections[0].port + '/' + mongoose.connections[0].name
  //Kill the current connection, then re-establish it
  mongoose.connection.close()
  mongoose.connect('mongodb://' + mongoPath, function(err){
    var asyncFunctions = []

    //Loop through all the known schemas, and execute an ensureIndex to make sure we're clean
    _.each(mongoose.connections[0].base.modelSchemas, function(schema, key) {
      asyncFunctions.push(function(cb){
        mongoose.model(key, schema).ensureIndexes(function(){
          return cb()
        })
      })
    })

    async.parallel(asyncFunctions, function(err) {
      console.log('Done dumping all collections and recreating indexes')
    })
  })
})

What I was looking for was this:

git diff <ref1>..<ref2> <dirname>

As an alternative SuperPutty has tabs and the option to run the same command across many terminals... might be what someone is looking for.

https://code.google.com/p/superputty/

It imports your PuTTY sessions too.

(Alt + Shift + X) , then M to Run Maven Build. You will need to specify the Maven goals you want on Run -> Run Configurations

You can use ctrl+F to find the text.
ctrl+h to enter the replacement text. Then ctrl+shift+h to replace the current selected text and move to next matched text.

This is for windows. But you can check in mac also for which you might want to check the key bindings under Preferences.

Example to collect the different fields from the object array

let inputArray = [
  { id: 1, name: "name1", value: "value1" },
  { id: 2, name: "name2", value: "value2" },
];

let ids = inputArray.map( (item) => item.id);
let names = inputArray.map((item) => item.name);
let values = inputArray.map((item) => item.value);

console.log(ids);
console.log(names);
console.log(values);

Result :

[ 1, 2 ]
[ 'name1', 'name2' ]
[ 'value1', 'value2' ]

Try this

SqlCommand cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID=@id", con);
cmd.Parameters.AddWithValue("id", id.Text);

In my case

• Checked if same user in itunes and xcode
• Checked bundle ID is same

Solution:

Go to itunes inside the page of my app and inside the first tab "App Information" under the right hand side has a section "Others Information" click on the "edit user permission" and grant xcode user the permission to read the information of the app.

With 500k documents, there is no reason to scale whatsoever. A typical laptop with an SSD and 8GB of ram can easily do 10s of millions of records, so if you are trying to pick because of scaling your choice doesn't really matter. I would suggest you pick what you like the most, and perhaps where you can find the most online support with.
