Programs & Examples On #Application structure

This is the Kotlin way:

In fragment_map.xml you should have:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

In your MapFragment.kt you should have:

    private fun setupMap() {
        (childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?)!!.getMapAsync(this)
    }

Call setupMap() in onCreateView.

Late answer, but I just came on this list today!

CREATE TABLE assignment_20101120 AS SELECT * FROM assignment;

Does the same.

You can define your own exception class extending java.lang.Exception (that's for a checked exception - these which must be caught), or extending java.lang.RuntimeException - these exceptions does not have to be caught.

The other solution is to review the Java API and finding an appropriate exception describing your situation: in this particular case I think that the best one would be IllegalArgumentException.

Pros:

Clustered indexes work great for ranges (e.g. select * from my_table where my_key between @min and @max)

In some conditions, the DBMS will not have to do work to sort if you use an orderby statement.

Cons:

Clustered indexes are can slow down inserts because the physical layouts of the records have to be modified as records are put in if the new keys are not in sequential order.

while true ; do
    ...
    if [ something ]; then
        break
    fi
done

I would like to run an automation test in different environments.
So I add this to command maven command:

spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=productionEnv1"

Here is the link where I found the solution: [1]https://github.com/spring-projects/spring-boot/issues/1095

The best way is:

git checkout -b <new_branch> <remote repo name>/<new_branch>

add layout_gravity="center" or "center_horizontal" to the parent layout.

On a side note, your LinearLayout inside your TableRow seems un-necessary, as a TableRow is already an horizontal LinearLayout.

You can use csvreader api & download from following location:

http://sourceforge.net/projects/javacsv/files/JavaCsv/JavaCsv%202.1/javacsv2.1.zip/download

or

http://sourceforge.net/projects/javacsv/

Use the following code:

/ ************ For Reading ***************/

import java.io.FileNotFoundException;
import java.io.IOException;

import com.csvreader.CsvReader;

public class CsvReaderExample {

    public static void main(String[] args) {
        try {

            CsvReader products = new CsvReader("products.csv");

            products.readHeaders();

            while (products.readRecord())
            {
                String productID = products.get("ProductID");
                String productName = products.get("ProductName");
                String supplierID = products.get("SupplierID");
                String categoryID = products.get("CategoryID");
                String quantityPerUnit = products.get("QuantityPerUnit");
                String unitPrice = products.get("UnitPrice");
                String unitsInStock = products.get("UnitsInStock");
                String unitsOnOrder = products.get("UnitsOnOrder");
                String reorderLevel = products.get("ReorderLevel");
                String discontinued = products.get("Discontinued");

                // perform program logic here
                System.out.println(productID + ":" + productName);
            }

            products.close();

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}

Write / Append to CSV file

Code:

/************* For Writing ***************************/

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

import com.csvreader.CsvWriter;

public class CsvWriterAppendExample {

    public static void main(String[] args) {

        String outputFile = "users.csv";

        // before we open the file check to see if it already exists
        boolean alreadyExists = new File(outputFile).exists();

        try {
            // use FileWriter constructor that specifies open for appending
            CsvWriter csvOutput = new CsvWriter(new FileWriter(outputFile, true), ',');

            // if the file didn't already exist then we need to write out the header line
            if (!alreadyExists)
            {
                csvOutput.write("id");
                csvOutput.write("name");
                csvOutput.endRecord();
            }
            // else assume that the file already has the correct header line

            // write out a few records
            csvOutput.write("1");
            csvOutput.write("Bruce");
            csvOutput.endRecord();

            csvOutput.write("2");
            csvOutput.write("John");
            csvOutput.endRecord();

            csvOutput.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

This is my working example:

There's a great answer to a post about how to delete local only branches. In it, the fellow builds a command to list out the local branches:

git branch -vv | cut -c 3- | awk '$3 !~/\[/ { print $1 }'

The answer has a great explanation about how this command was derived, so I would suggest you go and read that post.

A thread dump is a dump of the stacks of all live threads. Thus useful for analysing what an app is up to at some point in time, and if done at intervals handy in diagnosing some kinds of 'execution' problems (e.g. thread deadlock).

A heap dump is a dump of the state of the Java heap memory. Thus useful for analysing what use of memory an app is making at some point in time so handy in diagnosing some memory issues, and if done at intervals handy in diagnosing memory leaks.

This is what they are in 'raw' terms, and could be provided in many ways. In general used to describe dumped files from JVMs and app servers, and in this form they are a low level tool. Useful if for some reason you can't get anything else, but you will find life easier using decent profiling tool to get similar but easier to dissect info.

With respect to WebSphere a javacore file is a thread dump, albeit with a lot of other info such as locks and loaded classes and some limited memory usage info, and a PHD file is a heap dump.

If you want to read a javacore file you can do so by hand, but there is an IBM tool (BM Thread and Monitor Dump Analyzer) which makes it simpler. If you want to read a heap dump file you need one of many IBM tools: MDD4J or Heap Analyzer.

When using http client 4.5 I had to use the javasx.net.ssl.HostnameVerifier to allow any hostname (for testing purposes). Here is what I ended up doing:

CloseableHttpClient httpClient = null;
    try {
        SSLContextBuilder sslContextBuilder = new SSLContextBuilder();
        sslContextBuilder.loadTrustMaterial(null, new TrustSelfSignedStrategy());

        HostnameVerifier hostnameVerifierAllowAll = new HostnameVerifier() 
            {
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            };

        SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContextBuilder.build(), hostnameVerifierAllowAll);

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
            new AuthScope("192.168.30.34", 8443),
            new UsernamePasswordCredentials("root", "password"));

        httpClient = HttpClients.custom()
            .setSSLSocketFactory(sslSocketFactory)
            .setDefaultCredentialsProvider(credsProvider)
            .build();

        HttpGet httpGet = new HttpGet("https://192.168.30.34:8443/axis/services/getStuff?firstResult=0&maxResults=1000");

        CloseableHttpResponse response = httpClient.execute(httpGet);

        int httpStatus = response.getStatusLine().getStatusCode();
        if (httpStatus >= 200 && httpStatus < 300) { [...]
        } else {
            throw new ClientProtocolException("Unexpected response status: " + httpStatus);
        }

    } catch (Exception ex) {
        ex.printStackTrace();
    }
    finally {
        try {
            httpClient.close();
        } catch (IOException ex) {
            logger.error("Error while closing the HTTP client: ", ex);
        }
    }

If you use GNU find, since version 4.3.3 you can do:

find -newerct "1 Aug 2013" ! -newerct "1 Sep 2013" -ls

It will accept any date string accepted by GNU date -d.

You can change the c in -newerct to any of a, B, c, or m for looking at atime/birth/ctime/mtime.

Another example - list files modified between 17:30 and 22:00 on Nov 6 2017:

find -newermt "2017-11-06 17:30:00" ! -newermt "2017-11-06 22:00:00" -ls

Full details from man find:

   -newerXY reference
          Compares the timestamp of the current file with reference.  The reference argument is normally the name of a file (and one of its timestamps  is  used
          for  the  comparison)  but  it may also be a string describing an absolute time.  X and Y are placeholders for other letters, and these letters select
          which time belonging to how reference is used for the comparison.

          a   The access time of the file reference
          B   The birth time of the file reference
          c   The inode status change time of reference
          m   The modification time of the file reference
          t   reference is interpreted directly as a time

          Some combinations are invalid; for example, it is invalid for X to be t.  Some combinations are not implemented on all systems; for example B  is  not
          supported on all systems.  If an invalid or unsupported combination of XY is specified, a fatal error results.  Time specifications are interpreted as
          for the argument to the -d option of GNU date.  If you try to use the birth time of a reference file, and the birth time cannot be determined, a fatal
          error  message  results.   If  you  specify a test which refers to the birth time of files being examined, this test will fail for any files where the
          birth time is unknown.

If you have problems using the location: http://dl-ssl.google.com/android/eclipse/, try editing the location by replacing "http" with "https" or the other way round.

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:

• Informing each search engine of the location through their provided interface
• Adding url to the robots.txt file
• Submiting url to search engines through http

So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.

Thanks very much for all this. I used the following code in my Objective-C iPhone app:

const double PIx = 3.141592653589793;
const double RADIO = 6371; // Mean radius of Earth in Km

double convertToRadians(double val) {

   return val * PIx / 180;
}

-(double)kilometresBetweenPlace1:(CLLocationCoordinate2D) place1 andPlace2:(CLLocationCoordinate2D) place2 {

        double dlon = convertToRadians(place2.longitude - place1.longitude);
        double dlat = convertToRadians(place2.latitude - place1.latitude);

        double a = ( pow(sin(dlat / 2), 2) + cos(convertToRadians(place1.latitude))) * cos(convertToRadians(place2.latitude)) * pow(sin(dlon / 2), 2);
        double angle = 2 * asin(sqrt(a));

        return angle * RADIO;
}

Latitude and Longitude are in decimal. I didn't use min() for the asin() call as the distances that I'm using are so small that they don't require it.

It gave incorrect answers until I passed in the values in Radians - now it's pretty much the same as the values obtained from Apple's Map app :-)

Extra update:

If you are using iOS4 or later then Apple provide some methods to do this so the same functionality would be achieved with:

-(double)kilometresBetweenPlace1:(CLLocationCoordinate2D) place1 andPlace2:(CLLocationCoordinate2D) place2 {

    MKMapPoint  start, finish;


    start = MKMapPointForCoordinate(place1);
    finish = MKMapPointForCoordinate(place2);

    return MKMetersBetweenMapPoints(start, finish) / 1000;
}

Specifically in Commons Codec: class Base64 to decode(byte[] array) or encode(byte[] array)

If you know what class the field is on you can access it using reflection. This example (it's in Groovy but the method calls are identical) gets a Field object for the class Foo and gets its value for the object b. It shows that you don't have to care about the exact concrete class of the object, what matters is that you know the class the field is on and that that class is either the concrete class or a superclass of the object.

groovy:000> class Foo { def stuff = "asdf"}
===> true
groovy:000> class Bar extends Foo {}
===> true
groovy:000> b = new Bar()
===> Bar@1f2be27
groovy:000> f = Foo.class.getDeclaredField('stuff')
===> private java.lang.Object Foo.stuff
groovy:000> f.getClass()
===> class java.lang.reflect.Field
groovy:000> f.setAccessible(true)
===> null
groovy:000> f.get(b)
===> asdf

You can set this globally for all read.csv/read.* commands with options(stringsAsFactors=F)

Then read the file as follows: my.tab <- read.table( "filename.csv", as.is=T )

I use PHP to find the URL and match the page name (without the extension of .php, also I can add multiple pages that all have the same word in common like contact, contactform, etc. All will have that class added) and add a class with PHP to change the color, etc. For that you would have to save your pages with file extension .php.

Here is a demo. Change your links and pages as required. The CSS class for all the links is .tab and for the active link there is also another class of .currentpage (as is the PHP function) so that is where you will overwrite your CSS rules. You could name them whatever you like.

<?php # Using REQUEST_URI
    $currentpage = $_SERVER['REQUEST_URI'];?>
    <div class="nav">
        <div class="tab
             <?php
                 if(preg_match("/index/i", $currentpage)||($currentpage=="/"))
                     echo " currentpage";
             ?>"><a href="index.php">Home</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/services/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="services.php">Services</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/about/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="about.php">About</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/contact/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="contact.php">Contact</a>

Generally it means that you are providing an index for which a list element does not exist.

E.g, if your list was [1, 3, 5, 7], and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.

repeated = str + str + str;

Sometimes simple is best. Everyone reading the code can see what's happening.

And the compiler will do the fancy stuff with StringBuilder behind the scenes for you.

This may become useful to someone in the future as the new framework, when setup through VS, gets a default web.config, web.Debug.config and web.Release.config. In the web.release.config you will find this line:

<compilation xdt:Transform="RemoveAttributes(debug)" />

this was seeming to override any inline changes I made. I commented this line out and we were gravy (in terms of seeing non-minified code in a "release" build)

This is difficult to achieve, but the cookie expiration date can be set in another cookie. This cookie can then be read later to get the expiration date. Maybe there is a better way, but this is one of the methods to solve your problem.

I can think of at least two situations where you would want to have multiple .gitignore files in different (sub)directories.

• Different directories have different types of file to ignore. For example the .gitignore in the top directory of your project ignores generated programs, while Documentation/.gitignore ignores generated documentation.

• Ignore given files only in given (sub)directory (you can use /sub/foo in .gitignore, though).

Please remember that patterns in .gitignore file apply recursively to the (sub)directory the file is in and all its subdirectories, unless pattern contains '/' (so e.g. pattern name applies to any file named name in given directory and all its subdirectories, while /name applies to file with this name only in given directory).

To read the user input and store it in a variable, for later use, you can use SQL*Plus command ACCEPT.

Accept <your variable> <variable type if needed [number|char|date]> prompt 'message'

example

accept x number prompt 'Please enter something: '

And then you can use the x variable in a PL/SQL block as follows:

declare 
  a number;
begin
  a := &x;
end;
/

Working with a string example:

accept x char prompt 'Please enter something: '

declare 
  a varchar2(10);
begin
  a := '&x';   -- for a substitution variable of char data type 
end;           -- to be treated as a character string it needs
/              -- to be enclosed with single quotation marks

In the ideal case we should have enough memory to read the file in one read operation. That would be the best performer because we let the system manage File System , allocation units and HDD at will. In practice you are fortunate to know the file sizes in advance, just use the average file size rounded up to 4K (default allocation unit on NTFS). And best of all : create a benchmark to test multiple options.

To send to both remote with one command, you can create a alias for it:

git config alias.pushall '!git push origin devel && git push github devel'

With this, when you use the command git pushall, it will update both repositories.

You can try this:

var theValue = document.getElementById("demo").getAttribute("value");

I did not have enough reputation to comment and hence am adding a new answer.
Gasek answer is quite correct. Just one thing: if you are updating the .bash_profile file or the /etc/profile, those changes would be reflected only after you do a new login. In case you want to set the env variable and then use it in subsequent tasks in the same playbook, consider adding those environment variables in the .bashrc file.
I guess the reason behind this is the login and the non-login shells.
Ansible, while executing different tasks, reads the parameters from a .bashrc file instead of the .bash_profile or the /etc/profile.

As an example, if I updated my path variable to include the custom binary in the .bash_profile file of the respective user and then did a source of the file. The next subsequent tasks won't recognize my command. However if you update in the .bashrc file, the command would work.

 - name: Adding the path in the bashrc files
   lineinfile: dest=/root/.bashrc line='export PATH=$PATH:path-to-mysql/bin' insertafter='EOF' regexp='export PATH=\$PATH:path-to-mysql/bin' state=present
 
-  - name: Source the bashrc file
   shell: source /root/.bashrc

 - name: Start the mysql client
   shell: mysql -e "show databases";

This would work, but had I done it using profile files the mysql -e "show databases" would have given an error.

- name: Adding the path in the Profile files

This one won't work, if we have all these tasks in the same playbook.

Bash can be pretty obtuse sometimes.

The following commands all return different error messages for basically the same error:

$ echo hello >
bash: syntax error near unexpected token `newline`

$ echo hello > ${NONEXISTENT}
bash: ${NONEXISTENT}: ambiguous redirect

$ echo hello > "${NONEXISTENT}"
bash: : No such file or directory

Adding quotes around the variable seems to be a good way to deal with the "ambiguous redirect" message: You tend to get a better message when you've made a typing mistake -- and when the error is due to spaces in the filename, using quotes is the fix.

*********** PARSE THE RESULT TO JSON OBJECT: JSON.prase(result.arrayOfObjects) ***********

I came to this page after I faced this issue. So, my issue was that the server is sending array of objects in the form of string. It is something like this:

when I printed result on console after getting from server it is string:

'arrayOfObject': '[
                  {'id': '123', 'designation': 'developer'},
                  {'id': '422', 'designation': 'lead'}
               ]'

So, I have to convert this string to JSON after getting it from server. Use method for parsing the result string that you receive from server:

JSON.parse(result.arrayOfObjects)

While, @jamylak's approach is the better one, here is an alternative approach

>>> N=[2,3,5]
>>> P = 5
>>> type(P) in (tuple, list)
False
>>> type(N) in (tuple, list)
True

I was able to call stored procedure in a view (SQL Server 2005).

CREATE FUNCTION [dbo].[dimMeasure] 
   RETURNS  TABLE  AS

    (
     SELECT * FROM OPENROWSET('SQLNCLI', 'Server=localhost; Trusted_Connection=yes;', 'exec ceaw.dbo.sp_dimMeasure2')
    )
RETURN
GO

Inside stored procedure we need to set:

set nocount on
SET FMTONLY OFF

CREATE VIEW [dbo].[dimMeasure]
AS

SELECT * FROM OPENROWSET('SQLNCLI', 'Server=localhost;Trusted_Connection=yes;', 'exec ceaw.dbo.sp_dimMeasure2')

GO

Refer to Automatically Wrap Text in Label. It describes how to create your own growing label.

Here is the full source taken from the above reference:

using System;
using System.Text;
using System.Drawing;
using System.Windows.Forms;

public class GrowLabel : Label {
  private bool mGrowing;
  public GrowLabel() {
    this.AutoSize = false;
  }
  private void resizeLabel() {
    if (mGrowing) return;
    try {
      mGrowing = true;
      Size sz = new Size(this.Width, Int32.MaxValue);
      sz = TextRenderer.MeasureText(this.Text, this.Font, sz, TextFormatFlags.WordBreak);
      this.Height = sz.Height;
    }
    finally {
      mGrowing = false;
    }
  }
  protected override void OnTextChanged(EventArgs e) {
    base.OnTextChanged(e);
    resizeLabel();
  }
  protected override void OnFontChanged(EventArgs e) {
    base.OnFontChanged(e);
    resizeLabel();
  }
  protected override void OnSizeChanged(EventArgs e) {
    base.OnSizeChanged(e);
    resizeLabel();
  }
}

You can use itertools.count() to generate unbounded sequences. (itertools is in the Python standard library). Docs here:
https://docs.python.org/3/library/itertools.html#itertools.count

The best and easy way for image resize using Java Swing is:

jLabel.setIcon(new ImageIcon(new javax.swing.ImageIcon(getClass().getResource("/res/image.png")).getImage().getScaledInstance(200, 50, Image.SCALE_SMOOTH)));

For better display, identify the actual height & width of image and resize based on width/height percentage

This code snippet:

int& func1()
{
    int i;
    i = 1;
    return i;
}

will not work because you're returning an alias (a reference) to an object with a lifetime limited to the scope of the function call. That means once func1() returns, int i dies, making the reference returned from the function worthless because it now refers to an object that doesn't exist.

int main()
{
    int& p = func1();
    /* p is garbage */
}

The second version does work because the variable is allocated on the free store, which is not bound to the lifetime of the function call. However, you are responsible for deleteing the allocated int.

int* func2()
{
    int* p;
    p = new int;
    *p = 1;
    return p;
}

int main()
{
    int* p = func2();
    /* pointee still exists */
    delete p; // get rid of it
}

Typically you would wrap the pointer in some RAII class and/or a factory function so you don't have to delete it yourself.

In either case, you can just return the value itself (although I realize the example you provided was probably contrived):

int func3()
{
    return 1;
}

int main()
{
    int v = func3();
    // do whatever you want with the returned value
}

Note that it's perfectly fine to return big objects the same way func3() returns primitive values because just about every compiler nowadays implements some form of return value optimization:

class big_object 
{ 
public:
    big_object(/* constructor arguments */);
    ~big_object();
    big_object(const big_object& rhs);
    big_object& operator=(const big_object& rhs);
    /* public methods */
private:
    /* data members */
};

big_object func4()
{
    return big_object(/* constructor arguments */);
}

int main()
{
     // no copy is actually made, if your compiler supports RVO
    big_object o = func4();    
}

Interestingly, binding a temporary to a const reference is perfectly legal C++.

int main()
{
    // This works! The returned temporary will last as long as the reference exists
    const big_object& o = func4();    
    // This does *not* work! It's not legal C++ because reference is not const.
    // big_object& o = func4();  
}

You can't do that in JavaScript, since JS is executed in the browser, not in the server, so it didn't know anything about directories or other server resources.

The best option is using a server side script like the one posted by jellyfishtree.

If you're interested in seeing which specific headers a remote client is sending to your server, and you can cause the request to run a CGI script, then the simplest solution is to have your server script dump the environment variables into a file somewhere.

e.g. run the shell command "env > /tmp/headers" from within your script

Then, look for the environment variables that start with HTTP_...

You will see lines like:

HTTP_ACCEPT=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
HTTP_ACCEPT_ENCODING=gzip, deflate
HTTP_ACCEPT_LANGUAGE=en-US,en;q=0.5
HTTP_CACHE_CONTROL=max-age=0

Each of those represents a request header.

Note that the header names are modified from the actual request. For example, "Accept-Language" becomes "HTTP_ACCEPT_LANGUAGE", and so on.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

Your loop does not do anything because your counter z is 0 (and 0 < 0 evaluates to false, so the loop never starts).

Instead, if you have access to C++11 (and you really should aim for that!) try to use iterators, e.g. by using the non-member function std::begin() and std::end(), and a range-for loop to display the result:

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

int main() 
{
    int z = 0;
    string name[] = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    sort(begin(name),end(name));

    for(auto n: name){
         cout << n << endl;
    }
    return 0;    
}

Live example.

What does copying an object mean? There are a few ways you can copy objects--let's talk about the 2 kinds you're most likely referring to--deep copy and shallow copy.

Since we're in an object-oriented language (or at least are assuming so), let's say you have a piece of memory allocated. Since it's an OO-language, we can easily refer to chunks of memory we allocate because they are usually primitive variables (ints, chars, bytes) or classes we defined that are made of our own types and primitives. So let's say we have a class of Car as follows:

class Car //A very simple class just to demonstrate what these definitions mean.
//It's pseudocode C++/Javaish, I assume strings do not need to be allocated.
{
private String sPrintColor;
private String sModel;
private String sMake;

public changePaint(String newColor)
{
   this.sPrintColor = newColor;
}

public Car(String model, String make, String color) //Constructor
{
   this.sPrintColor = color;
   this.sModel = model;
   this.sMake = make;
}

public ~Car() //Destructor
{
//Because we did not create any custom types, we aren't adding more code.
//Anytime your object goes out of scope / program collects garbage / etc. this guy gets called + all other related destructors.
//Since we did not use anything but strings, we have nothing additional to handle.
//The assumption is being made that the 3 strings will be handled by string's destructor and that it is being called automatically--if this were not the case you would need to do it here.
}

public Car(const Car &other) // Copy Constructor
{
   this.sPrintColor = other.sPrintColor;
   this.sModel = other.sModel;
   this.sMake = other.sMake;
}
public Car &operator =(const Car &other) // Assignment Operator
{
   if(this != &other)
   {
      this.sPrintColor = other.sPrintColor;
      this.sModel = other.sModel;
      this.sMake = other.sMake;
   }
   return *this;
}

}

A deep copy is if we declare an object and then create a completely separate copy of the object...we end up with 2 objects in 2 completely sets of memory.

Car car1 = new Car("mustang", "ford", "red");
Car car2 = car1; //Call the copy constructor
car2.changePaint("green");
//car2 is now green but car1 is still red.

Now let's do something strange. Let's say car2 is either programmed wrong or purposely meant to share the actual memory that car1 is made of. (It's usually a mistake to do this and in classes is usually the blanket it's discussed under.) Pretend that anytime you ask about car2, you're really resolving a pointer to car1's memory space...that's more or less what a shallow copy is.

//Shallow copy example
//Assume we're in C++ because it's standard behavior is to shallow copy objects if you do not have a constructor written for an operation.
//Now let's assume I do not have any code for the assignment or copy operations like I do above...with those now gone, C++ will use the default.

 Car car1 = new Car("ford", "mustang", "red"); 
 Car car2 = car1; 
 car2.changePaint("green");//car1 is also now green 
 delete car2;/*I get rid of my car which is also really your car...I told C++ to resolve 
 the address of where car2 exists and delete the memory...which is also
 the memory associated with your car.*/
 car1.changePaint("red");/*program will likely crash because this area is
 no longer allocated to the program.*/

So regardless of what language you're writing in, be very careful about what you mean when it comes to copying objects because most of the time you want a deep copy.

What are the copy constructor and the copy assignment operator? I have already used them above. The copy constructor is called when you type code such as Car car2 = car1; Essentially if you declare a variable and assign it in one line, that's when the copy constructor is called. The assignment operator is what happens when you use an equal sign--car2 = car1;. Notice car2 isn't declared in the same statement. The two chunks of code you write for these operations are likely very similar. In fact the typical design pattern has another function you call to set everything once you're satisfied the initial copy/assignment is legitimate--if you look at the longhand code I wrote, the functions are nearly identical.

When do I need to declare them myself? If you are not writing code that is to be shared or for production in some manner, you really only need to declare them when you need them. You do need to be aware of what your program language does if you choose to use it 'by accident' and didn't make one--i.e. you get the compiler default. I rarely use copy constructors for instance, but assignment operator overrides are very common. Did you know you can override what addition, subtraction, etc. mean as well?

How can I prevent my objects from being copied? Override all of the ways you're allowed to allocate memory for your object with a private function is a reasonable start. If you really don't want people copying them, you could make it public and alert the programmer by throwing an exception and also not copying the object.

It works in Python too:

>>> 1+\
      2+\
3
6
>>> (1+
          2+
 3)
6

TortoiseSVN users: right click on the root project directory > TortoiseSVN > Clean up... (make sure you check all the boxes). This worked for me.

I experienced the same issue, same version of Chrome though it's unrelated to the issue. With the developer console I captured an instance of the request that spawned this, and it is an API call served by ad.doubleclick.net. Specifically, this resource returns a response with Content-Disposition: attachment; filename="f.txt".

The URL I happened to capture was https://ad.doubleclick.net/adj/N7412.226578.VEVO/B8463950.115078190;sz=300x60...

Per curl:

The standard approach is to use the select module.

However, this doesn't work on Windows. For that, you can use the msvcrt module's keyboard polling.

Often, this is done with multiple threads -- one per device being "watched" plus the background processes that might need to be interrupted by the device.

This is solution from my point of view:

ok.setOnClickListener(this);
@Override
public void onClick(View view) {
    if(view == ok){
        Intent intent = new Intent(Intent.ACTION_CALL);
        intent.setData(Uri.parse("tel:" + num));
        activity.startActivity(intent);

    }

Of course in Activity (class) definition you have to implement View.OnClickListener .

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

In my point of view, they mean the same activity but from different perspectives:

Think about that, Alice makes some commits on repository A, which was forked from Bob's repository B.

When Alice wants to "merge" her changes into B, she actually wants Bob to "pull" these changes from A.

Therefore, from Alice's point of view, it is a "merge request", while Bob views it as a "pull request".

You don't need to extend the Walker. This will do:

function overrideSubmenuClasses( $classes ) {
    $classes[] = 'myclass1';
    $classes[] = 'myclass2';

    return $classes;
}
add_action('nav_menu_submenu_css_class', 'overrideSubmenuClasses');

I like to see a green tick in the top right corner in PyCharm. I append the variable names with an underscore just to clear this warning so I can focus on the important warnings.

data = [4, 5, 6]

def print_data(data_):
    print(data_)

print_data(data)

HTML

You can use match() as well:

if (str.match(/^([a-z0-9]{5,})$/)) {
    alert("match!");
}

But test() seems to be faster as you can read here.

Important difference between match() and test():

match() works only with strings, but test() works also with integers.

12345.match(/^([a-z0-9]{5,})$/); // ERROR
/^([a-z0-9]{5,})$/.test(12345);  // true
/^([a-z0-9]{5,})$/.test(null);   // false

// Better watch out for undefined values
/^([a-z0-9]{5,})$/.test(undefined); // true

If you have password for your dB then

mysql -u <username> -p <DBName> < yourfile.sql

You can't trigger the native validation UI (see edit below), but you can easily take advantage of the validation API on arbitrary input elements:

$('input').blur(function(event) {
    event.target.checkValidity();
}).bind('invalid', function(event) {
    setTimeout(function() { $(event.target).focus();}, 50);
});

The first event fires checkValidity on every input element as soon as it loses focus, if the element is invalid then the corresponding event will be fired and trapped by the second event handler. This one sets the focus back to the element, but that could be quite annoying, I assume you have a better solution for notifying about the errors. Here's a working example of my code above.

EDIT: All modern browsers support the reportValidity() method for native HTML5 validation, per this answer.

M-^ is copy Text. "M" in my environment is "Esc" key ! not "Ctrl"; so I use Esc + 6 to copy that.

[nano help] Escape-key sequences are notated with the Meta (M-) symbol and can be entered using either the Esc, Alt, or Meta key depending on your keyboard setup.

Others have already given you links to documentation.

You can try the following in a interactive shell:

>>> assert 5 > 2
>>> assert 2 > 5
Traceback (most recent call last):
  File "<string>", line 1, in <fragment>
builtins.AssertionError:

The first statement does nothing, while the second raises an exception. This is the first hint: asserts are useful to check conditions that should be true in a given position of your code (usually, the beginning (preconditions) and the end of a function (postconditions)).

Asserts are actually highly tied to programming by contract, which is a very useful engineering practice:

This worked for me on Windows 8.1 and Windows 10.

git config --global mergetool.meld.path "/c/Program Files (x86)/meld/meld.exe"

The trick is this line

((TextView) view).setTextColor(ContextCompat.getColor(mContext, R.color.login_input_hint_color));

use it in the onItemSelected. Here is my code with more context

List<String> list = getLabels(); // First item will be the placeholder
        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_spinner_item, list);
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(dataAdapter);
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                // First item will be gray
                if (position == 0) {
                    ((TextView) view).setTextColor(ContextCompat.getColor(mContext, R.color.login_input_hint_color));
                } else {
                    ((TextView) view).setTextColor(ContextCompat.getColor(mContext, R.color.primary_text));
                }
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

Changing the background property might not be enough as the component won't look like a button anymore. You might need to re-implement the paint method as in here to get a better result:

bmjohns -> You are my life saviour. That is the only working solution (With the AppUtility struct)

I've created this class:

class Helper{
    struct AppUtility {

        static func lockOrientation(_ orientation: UIInterfaceOrientationMask) {

            if let delegate = UIApplication.shared.delegate as? AppDelegate {
                delegate.orientationLock = orientation
            }
        }

        /// OPTIONAL Added method to adjust lock and rotate to the desired orientation
        static func lockOrientation(_ orientation: UIInterfaceOrientationMask, andRotateTo rotateOrientation:UIInterfaceOrientation) {

            self.lockOrientation(orientation)

            UIDevice.current.setValue(rotateOrientation.rawValue, forKey: "orientation")
        }

    }
}

and followed your instructions, and everything works perfectly for Swift 3 -> xcode version 8.2.1

For i As Integer = 0 To 100
    bool = False
    For j As Integer = 0 To 100
        If check condition Then
            'if condition match
            bool = True
            Exit For 'Continue For
        End If
    Next
    If bool = True Then Continue For
Next

I was just tinkering with danteuno's answer and found that while good-intentioned, sadly it's broken on several browsers that are not IE. This is because IE will be quite strict about what it accepts as the argument to the Date constructor, but others will not. For example, Chrome 18 gives

> new Date("66")
  Sat Jan 01 1966 00:00:00 GMT+0200 (GTB Standard Time)

This causes the code to take the "compare dates" path and it all goes downhill from there (e.g. new Date("11") is greater than new Date("66") and this is obviously the opposite of the desired effect).

Therefore after consideration I modified the code to give priority to the "numbers" path over the "dates" path and validate that the input is indeed numeric with the excellent method provided in Validate decimal numbers in JavaScript - IsNumeric().

In the end, the code becomes:

$.validator.addMethod(
    "greaterThan",
    function(value, element, params) {
        var target = $(params).val();
        var isValueNumeric = !isNaN(parseFloat(value)) && isFinite(value);
        var isTargetNumeric = !isNaN(parseFloat(target)) && isFinite(target);
        if (isValueNumeric && isTargetNumeric) {
            return Number(value) > Number(target);
        }

        if (!/Invalid|NaN/.test(new Date(value))) {
            return new Date(value) > new Date(target);
        }

        return false;
    },
    'Must be greater than {0}.');

npm install -g npm@4

This will install the latest version on the major release 4, no no need to specify version number. Replace 4 with whatever major release you want.

One possible could be like this,

HTML

<div class="box-left-mini">
    <div class="front">this div is infront</div>
    <div class="behind">
        this div is behind
    </div>
</div>

CSS

.box-left-mini{
float:left;
background-image:url(website-content/hotcampaign.png);
width:292px;
height:141px;
}
.front{
    background-color:lightgreen;
}
.behind{
    background-color:grey;
    position:absolute;
    width:100%;
    height:100%;
    top:0;
    z-index:-1;
}

http://jsfiddle.net/MgtWS/

But it really depends on the layout of your div elements i.e. if they are floating, or absolute positioned etc.

I developed a generic statement to apply the filter:

string rowFilter = string.Format("[{0}] = '{1}'", columnName, filterValue);
(myDataGridView.DataSource as DataTable).DefaultView.RowFilter = rowFilter;

The square brackets allow for spaces in the column name.

Additionally, if you want to include multiple values in your filter, you can add the following line for each additional value:

rowFilter += string.Format(" OR [{0}] = '{1}'", columnName, additionalFilterValue);

There are 2 options:

set serveroutput on format wrapped;

or

Open the 'view' menu and click on 'dbms output'. You should get a dbms output window at the bottom of the worksheet. You then need to add the connection (for some reason this is not done automatically).

A simple one would be

\d{4}-\d{2}-\d{2}

Debuggex Demo

but this does not restrict month to 1-12 and days from 1 to 31.

There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.

If you are facing same problem as mine. Here is the solution which works for me.

1. Uninstall every python and anaconda.
2. Download anaconda from here "http://continuum.io/downloads" and only install it (no other python is needed).
3. Open spyder and import.

4. If you get any error, type in command prompt

   pip install module_name

I hope it will work for you too

Like this:

xy.list <- split(xy.df, seq(nrow(xy.df)))

And if you want the rownames of xy.df to be the names of the output list, you can do:

xy.list <- setNames(split(xy.df, seq(nrow(xy.df))), rownames(xy.df))

That error can only be caused by one of three things:

1. Your JavaScript file is not being properly loaded into your page
2. You have a botched version of jQuery. This could happen because someone edited the core file, or a plugin may have overwritten the $ variable.
3. You have JavaScript running before the page is fully loaded, and as such, before jQuery is fully loaded.

First of all, ensure, what script is call properly, it should looks like

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>

and shouldn't have attributes async or defer.

Then you should check the Firebug net panel to see if the file is actually being loaded properly. If not, it will be highlighted red and will say "404" beside it. If the file is loading properly, that means that the issue is number 2.

Make sure all jQuery javascript code is being run inside a code block such as:

$(document).ready(function () {
  //your code here
});

This will ensure that your code is being loaded after jQuery has been initialized.

One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described.

Note: If you're loading code which does not require jQuery to run it does not need to be placed inside the jQuery ready handler. That code may be separated using document.readyState.

if wants to convert UTC date to milliseconds
syntax : Date.UTC(year, month, ?day, ?hours, ?min, ?sec, ?milisec);
e.g :
date_in_mili = Date.UTC(2020, 07, 03, 03, 40, 40, 40);
console.log('miliseconds', date_in_mili);

When to use LIBXML_NOCDATA ?

I add the issue when transforming XML to JSON.

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo json_encode($xml, true); 
/* prints
   {
     "content": {}
   }
 */

When accessing the SimpleXMLElement object, It gets the CDATA :

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo $xml->content; 
/* prints
   Hello, world!
*/

I makes sense to use LIBXML_NOCDATA because json_encode don't access the SimpleXMLElement to trigger the string casting feature, I'm guessing a __toString() equivalent.

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>", null, LIBXML_NOCDATA);
echo json_encode($xml);
/*
 {
   "content": "Hello, world!"
 }
*/

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

You can add security provider by editing java.security with using following code with creating static block:

static {
    Security.addProvider(new BouncyCastleProvider());
}

If you are using maven project, then you will have to add dependency for BouncyCastleProvider as follows in pom.xml file of your project.

<dependency>
            <groupId>org.bouncycastle</groupId>
            <artifactId>bcprov-jdk15on</artifactId>
            <version>1.47</version>
</dependency>

If you are using normal java project, then you can add download bcprov-jdk15on-147.jar from the link given below and edit your classpath.

http://www.java2s.com/Code/Jar/b/Downloadbcprovextjdk15on147jar.htm

What about to use the specialized version of the "bind" command "one". Once the event handler executes the first time, it’s automatically removed as an event handler.

$(window).one("beforeunload", BeforeUnload);

It seems that OpenQA, guys behind Selenium, have already addressed this problem. They defined some variables to explicitely match whitespaces. In my case, I need to use an XPATH similar to //td[text()="${nbsp}"].

I reproduced here the text from OpenQA concerning this issue (found here):

HTML automatically normalizes whitespace within elements, ignoring leading/trailing spaces and converting extra spaces, tabs and newlines into a single space. When Selenium reads text out of the page, it attempts to duplicate this behavior, so you can ignore all the tabs and newlines in your HTML and do assertions based on how the text looks in the browser when rendered. We do this by replacing all non-visible whitespace (including the non-breaking space " ") with a single space. All visible newlines (<br>, <p>, and <pre> formatted new lines) should be preserved.

We use the same normalization logic on the text of HTML Selenese test case tables. This has a number of advantages. First, you don't need to look at the HTML source of the page to figure out what your assertions should be; " " symbols are invisible to the end user, and so you shouldn't have to worry about them when writing Selenese tests. (You don't need to put " " markers in your test case to assertText on a field that contains " ".) You may also put extra newlines and spaces in your Selenese <td> tags; since we use the same normalization logic on the test case as we do on the text, we can ensure that assertions and the extracted text will match exactly.

This creates a bit of a problem on those rare occasions when you really want/need to insert extra whitespace in your test case. For example, you may need to type text in a field like this: "foo ". But if you simply write <td>foo </td> in your Selenese test case, we'll replace your extra spaces with just one space.

This problem has a simple workaround. We've defined a variable in Selenese, ${space}, whose value is a single space. You can use ${space} to insert a space that won't be automatically trimmed, like this: <td>foo${space}${space}${space}</td>. We've also included a variable ${nbsp}, that you can use to insert a non-breaking space.

Note that XPaths do not normalize whitespace the way we do. If you need to write an XPath like //div[text()="hello world"] but the HTML of the link is really "hello world", you'll need to insert a real " " into your Selenese test case to get it to match, like this: //div[text()="hello${nbsp}world"].

It can be done by code as follows:

import time
time.sleep(10)   #Set the time
for x in range(60):  
    time.sleep(1)
    print('\a')

The second way isn't valid XML; did you mean <numbers>[3,2,1]</numbers>?

If so, then the first one is preferred because all you need to get the array elements is some XML manipulation. On the second one you first need to get the value of the <numbers> element via XML manipulation, then somehow parse the [3,2,1] text using something else.

Or if you really want some compact format, you can consider using JSON (which "natively" supports arrays). But that depends on your application requirements.

I've found it.

When a page, that is located inside an area, wants to access a controller that is located outside of this area (such as a shared layout page or a certain page inside a different area), the area of this controller needs to be added. Since the common controller is not in a specific area but part of the main project, you have to leave area empty:

@Html.Action("MenuItems", "Common", new {area="" }) 

The above needs to be added to all of the actions and actionlinks since the layout page is shared throughout the various areas.

It's exactly the same problem as here: ASP.NET MVC Areas with shared layout

Edit: To be clear, this is marked as the answer because it was the answer for my problem. The above answers might solve the causes that trigger the same error.

You can also set the title of your chart by adding the title parameter as follows

ax.set(xlabel='common xlabel', ylabel='common ylabel', title='some title')

This is what worked for me.

Using multiple threads on CPython won't give you better performance for pure-Python code due to the global interpreter lock (GIL). I suggest using the multiprocessing module instead:

pool = multiprocessing.Pool(4)
out1, out2, out3 = zip(*pool.map(calc_stuff, range(0, 10 * offset, offset)))

Note that this won't work in the interactive interpreter.

To avoid the usual FUD around the GIL: There wouldn't be any advantage to using threads for this example anyway. You want to use processes here, not threads, because they avoid a whole bunch of problems.

function removeAccents(strAccents){
    strAccents = strAccents.split('');
    strAccentsOut = new Array();
    strAccentsLen = strAccents.length;
    var accents = 'ÀÁÂÃÄÅàáâãäåÒÓÔÕÕÖØòóôõöøÈÉÊËèéêëðÇçÐÌÍÎÏìíîïÙÚÛÜùúûüÑñŠšŸÿýŽž';
    var accentsOut = ['A','A','A','A','A','A','a','a','a','a','a','a','O','O','O','O','O','O','O','o','o','o','o','o','o','E','E','E','E','e','e','e','e','e','C','c','D','I','I','I','I','i','i','i','i','U','U','U','U','u','u','u','u','N','n','S','s','Y','y','y','Z','z'];
    for (var y = 0; y < strAccentsLen; y++) {
        if (accents.indexOf(strAccents[y]) != -1) {
            strAccentsOut[y] = accentsOut[accents.indexOf(strAccents[y])];
        }
        else
            strAccentsOut[y] = strAccents[y];
    }
    strAccentsOut = strAccentsOut.join('');
    return strAccentsOut;
}

I try to explain this problem step by step in following example.

0) Question

I try to ask you like this :

i want to open page like facebook profile www.facebook.com/kaila.piyush

it get id from url and parse it to profile.php file and return featch data from database and show user to his profile

normally when we develope any website its link look like www.website.com/profile.php?id=username example.com/weblog/index.php?y=2000&m=11&d=23&id=5678

now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink

http://example.com/profile/userid (get a profile by the ID) 
http://example.com/profile/username (get a profile by the username) 
http://example.com/myprofile (get the profile of the currently logged-in user)

1) .htaccess

Create a .htaccess file in the root folder or update the existing one :

Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
#  Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php

What does that do ?

If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.

2) index.php

Now, we want to know what action to trigger, so we need to read the URL :

In index.php :

// index.php    

// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);

for ($i= 0; $i < sizeof($scriptName); $i++)
{
    if ($requestURI[$i] == $scriptName[$i])
    {
        unset($requestURI[$i]);
    }
}

$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :

$command = array(
    [0] => 'profile',
    [1] => 19837,
    [2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :

// index.php

require_once("profile.php"); // We need this file
switch($command[0])
{
    case ‘profile’ :
        // We run the profile function from the profile.php file.
        profile($command([1]);
        break;
    case ‘myprofile’ :
        // We run the myProfile function from the profile.php file.
        myProfile();
        break;
    default:
        // Wrong page ! You could also redirect to your custom 404 page.
        echo "404 Error : wrong page.";
        break;
}

2) profile.php

Now in the profile.php file, we should have something like this :

// profile.php

function profile($chars)
{
    // We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)

    if (is_int($chars)) {
        $id = $chars;
        // Do the SQL to get the $user from his ID
        // ........
    } else {
        $username = mysqli_real_escape_string($char);
        // Do the SQL to get the $user from his username
        // ...........
    }

    // Render your view with the $user variable
    // .........
}

function myProfile()
{
    // Get the currently logged-in user ID from the session :
    $id = ....

    // Run the above function :
    profile($id);
}

I agree that cygwin/OpenSSH is the best choice, but its setup can be involved to say the least. Here is a document to get you started though: Installing OpenSSH

The second function should have:

var value = document.getElementById(id).value;

Then they are basically the same function.

The (^) XOR operator generates 1 when it is applied on two different bits (0 and 1). It generates 0 when it is applied on two same bits (0 and 0 or 1 and 1).

Here is complete article about streaming android camera video to a webpage.

2. On server side Wowza Media Engine is used to decode the video stream
3. Finally jWplayer is used to play the video on a webpage.

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

An alternative approach would involve storing the ranges in a table, instead of embedding them in the query. You would end up with a table, call it Ranges, that looks like this:

LowerLimit   UpperLimit   Range 
0              9          '0-9'
10            19          '10-19'
20            29          '20-29'
30            39          '30-39'

And a query that looks like this:

Select
   Range as [Score Range],
   Count(*) as [Number of Occurences]
from
   Ranges r inner join Scores s on s.Score between r.LowerLimit and r.UpperLimit
group by Range

This does mean setting up a table, but it would be easy to maintain when the desired ranges change. No code changes necessary!

if you do not want to create a custom class loader. You can read the jar file stream. And transfer it to a File object. Then you can get the url of the File. Send it to the URLClassLoader, you can load the jar file as you want. sample:

InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("example"+ ".jar");
final File tempFile = File.createTempFile("temp", ".jar");
tempFile.deleteOnExit();  // you can delete the temp file or not
try (FileOutputStream out = new FileOutputStream(tempFile)) {
    IOUtils.copy(resourceAsStream, out);
}
IOUtils.closeQuietly(resourceAsStream);
URL url = tempFile.toURI().toURL();
URLClassLoader urlClassLoader = new URLClassLoader(new URL[]{url});
urlClassLoader.loadClass()
...

Some operations are quicker than java heap space manager. Delaying operations for some time can free memory space. You can use this method to escape heap size error:

waitForGarbageCollector(new Runnable() {
  @Override
  public void run() {
    // Your operations.
  }
});

/**
 * Measure used memory and give garbage collector time to free up some
 * of the space.
 *
 * @param callback Callback operations to be done when memory is free.
 */
public static void waitForGarbageCollector(final Runnable callback) {

  Runtime runtime;
  long maxMemory;
  long usedMemory;
  double availableMemoryPercentage = 1.0;
  final double MIN_AVAILABLE_MEMORY_PERCENTAGE = 0.1;
  final int DELAY_TIME = 5 * 1000;

  runtime =
    Runtime.getRuntime();

  maxMemory =
    runtime.maxMemory();

  usedMemory =
    runtime.totalMemory() -
    runtime.freeMemory();

  availableMemoryPercentage =
    1 -
    (double) usedMemory /
    maxMemory;

  if (availableMemoryPercentage < MIN_AVAILABLE_MEMORY_PERCENTAGE) {
    try {
      Thread.sleep(DELAY_TIME);
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
    waitForGarbageCollector(
      callback);
  } else {
    // Memory resources are available, go to next operation:
    callback.run();
  }
}

u must specify the width and height also

You can also use REGEXP's synonym RLIKE as well.

For example:

SELECT *

Communicating between fragments is fairly complicated (I find the listeners concept a little challenging to implement).

It is common to use a 'Event Bus" to abstract these communications. This is a 3rd party library that takes care of this communication for you.

'Otto' is one that is used often to do this, and might be worth looking into: http://square.github.io/otto/

The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.

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

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

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

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

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

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

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

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

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

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

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

As a note: Chrome for Android states:

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

Custom Tiles for IE 11+ on Windows 8.1+

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

Microsoft recommends creating a few tiles at the following size:

Small: 128 x 128

Medium: 270 x 270

Wide: 558 x 270

Large: 558 x 558

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

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

<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
  <msapplication>

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

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

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

Putting it all together:

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

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

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

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

Windows Phone Live Tiles

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

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

Step 1

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

Step 2

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

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

Step 3

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

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

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

Step 4

Next you add some JS to toggle the overlay visibility

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

Note on Sizes

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

The logic is simple. setOnClickListener belongs to step 2.

1. You create the button
2. You create an instance of OnClickListener* like it's done in that example and override the onClick-method.
3. You assign that OnClickListener to that button using btn.setOnClickListener(myOnClickListener); in your fragments/activities onCreate-method.
4. When the user clicks the button, the onClick function of the assigned OnClickListener is called.

*If you import android.view.View; you use View.OnClickListener. If you import android.view.View.*; or import android.view.View.OnClickListener; you use OnClickListener as far as I get it.

Another way is to let you activity/fragment inherit from OnClickListener. This way you assign your fragment/activity as the listener for your button and implement onClick as a member-function.

Apparently it's possible to do this in jQuery:

$("#tabs").css("cssText", "height: 650px !important;");

Another way to get to the deleted commit is with the git fsck command.

git fsck --lost-found

This will output something like at the last line:

dangling commit xyz

We can check that it is the same commit using reflog as suggested in other answers. Now we can do a git merge

git merge xyz

Note:
We cannot get the commit back with fsck if we have already run a git gc command which will remove the reference to the dangling commit.

A useful shortcut from inside Sublime Text:

cmd-shift-P --> Browse Packages Now open user folder.

You can read a file to have an RDD and then assign schema to it. Two common ways to creating schema are either using a case class or a Schema object [my preferred one]. Follows the quick snippets of code that you may use.

Case Class approach

case class Test(id:String,name:String)
val myFile = sc.textFile("file.txt")
val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()

Schema Approach

import org.apache.spark.sql.types._
val schemaString = "id name"
val fields = schemaString.split(" ").map(fieldName => StructField(fieldName, StringType, nullable=true))
val schema = StructType(fields)

val dfWithSchema = sparkSess.read.option("header","false").schema(schema).csv("file.txt")
dfWithSchema.show()

The second one is my preferred approach since case class has a limitation of max 22 fields and this will be a problem if your file has more than 22 fields!

for create method:

-(void)mymethods:(NSString *)aCont withsecond:(NSString *)a-second {
//method definition...
}

for call the method:

[mymethods:self.contoCorrente withsecond:self.asecond];

TL;DR Use GetProcessVersion.

All of these function are available in Windows XP [desktop apps | UWP apps].

GetProcessVersion uses a Process ID and returns 0 if the process of the given id is not running.

GetExitCodeProcess uses a Process handle and gives you the process exit code, if the code is STILL_ACTIVE (259) the process is still running so you could check if it is not STILL_ACTIVE (259) meaning that the process is not running. This is likely to work in basically every situation, unless the process exits with code 259.

WaitForSingleObject uses a Process handle with the SYNCHRONIZE access right and returns 0 if the process is not running. You should not specify INFINITE for the dwMilliseconds parameter because the function would not return until the process state became signaled(process is terminated).

var id = $(this).dataset.id

works for me!

I know this was originally asked back in 2008, but there are some new functions that were introduced with SQL Server 2012. The FORMAT function simplifies padding left with zeros nicely. It will also perform the conversion for you:

declare @n as int = 2
select FORMAT(@n, 'd10') as padWithZeros

Update:

I wanted to test the actual efficiency of the FORMAT function myself. I was quite surprised to find the efficiency was not very good compared to the original answer from AlexCuse. Although I find the FORMAT function cleaner, it is not very efficient in terms of execution time. The Tally table I used has 64,000 records. Kudos to Martin Smith for pointing out execution time efficiency.

SET STATISTICS TIME ON
select FORMAT(N, 'd10') as padWithZeros from Tally
SET STATISTICS TIME OFF

SQL Server Execution Times: CPU time = 2157 ms, elapsed time = 2696 ms.

SET STATISTICS TIME ON
select right('0000000000'+ rtrim(cast(N as varchar(5))), 10) from Tally
SET STATISTICS TIME OFF

SQL Server Execution Times:

CPU time = 31 ms, elapsed time = 235 ms.

I tried to accomplish this using Class component: you can view the message for the same

.....

class Checkbox extends React.Component{
constructor(props){
    super(props)
    this.state={
        checked:true
    }
    this.handleCheck=this.handleCheck.bind(this)
}

handleCheck(){
    this.setState({
        checked:!this.state.checked
    })
}

render(){
    var msg=" "
    if(this.state.checked){
        msg="checked!"
    }else{
        msg="not checked!"
    }
    return(
        <div>
            <input type="checkbox" 
            onChange={this.handleCheck}
            defaultChecked={this.state.checked}
            />
            <p>this box is {msg}</p>
        </div>
    )
}

}

_{Since nobody referenced relevant documentation:}

CSS Transforms Module Level 1 - Terminology - Transformable Element

A transformable element is an element in one of these categories:

• an element whose layout is governed by the CSS box model which is either a block-level or atomic inline-level element, or whose display property computes to table-row, table-row-group, table-header-group, table-footer-group, table-cell, or table-caption
• an element in the SVG namespace and not governed by the CSS box model which has the attributes transform, ‘patternTransform‘ or gradientTransform.

In your case, the <a> elements are inline by default.

Changing the display property's value to inline-block renders the elements as atomic inline-level elements, and therefore the elements become "transformable" by definition.

li a {
   display: inline-block;
   -webkit-transform: rotate(10deg);
   -moz-transform: rotate(10deg);
   -o-transform: rotate(10deg); 
   transform: rotate(10deg);
}

As mentioned above, this only seems to applicable in -webkit based browsers since it appears to work in IE/FF regardless.

I had the same problem, "Rebuild Solution" and then "Clean Solution" didn't work.I solved that by checking my DLL references.

Below gives me opposite of what you have. (Notice Group column)

SELECT
    *
FROM
    myTable
GROUP BY
    Group_value,
    ID
ORDER BY
    count(Group_value)

Let me know if this is fine with you...

I am trying to get what you want too...

So.. I had noticed in event viewer that this crash corresponded to a "System.IO.FileNotFoundException" error.

So I fired ProcMon and noticed that one of the program dlls was failing to load vcruntime140. So I simply installed vs15 redist and it worked.

If you have a proper cors header in place. Your corporate network may be stripping off the cors header. If the website is externally accessible, try accessing it from outside your network to verify whether the network is causing the problem--a good idea regardless of the cause.

Swift 2.0

It seems that Swift 2.0 has actually introduced the String(data:encoding:) as an String extension when you import Foundation. I haven't found any place where this is documented, weirdly enough.

(pre Swift 2.0) Lightweight extension

Here's a copy-pasteable little extension without using NSString, let's cut the middle-man.

import Foundation

extension NSData
{
    var byteBuffer : UnsafeBufferPointer<UInt8> { get { return UnsafeBufferPointer<UInt8>(start: UnsafeMutablePointer<UInt8>(self.bytes), count: self.length) }}
}

extension String
{
    init?(data : NSData, encoding : NSStringEncoding)
    {
        self.init(bytes: data.byteBuffer, encoding: encoding)
    }
}

// Playground test
let original = "Nymphs blitz quick vex dwarf jog"
let encoding = NSASCIIStringEncoding

if let data = original.dataUsingEncoding(encoding)
{
    String(data: data, encoding: encoding)
}

This also give you access to data.byteBuffer which is a sequence type, so all those cool operations you can do with sequences also work, like doing a reduce { $0 &+ $1 } for a checksum.

Notes

In my previous edit, I used this method:

var buffer = Array<UInt8>(count: data.length, repeatedValue: 0x00)
data.getBytes(&buffer, length: data.length)
self.init(bytes: buffer, encoding: encoding)

The problem with this approach, is that I'm creating a copy of the information into a new array, thus, I'm duplicating the amount of bytes (specifically: encoding size * data.length)

This is an old thread but apparently the C++ Faq has a section (Archived 2013 version) on this. This apparently will be updated if the author is contacted so this will probably be more up to date in the long run, but here is the current version:

Depends on what you mean. If you mean, Is it possible to convert C++ to readable and maintainable C-code? then sorry, the answer is No — C++ features don't directly map to C, plus the generated C code is not intended for humans to follow. If instead you mean, Are there compilers which convert C++ to C for the purpose of compiling onto a platform that yet doesn't have a C++ compiler? then you're in luck — keep reading.

A compiler which compiles C++ to C does full syntax and semantic checking on the program, and just happens to use C code as a way of generating object code. Such a compiler is not merely some kind of fancy macro processor. (And please don't email me claiming these are preprocessors — they are not — they are full compilers.) It is possible to implement all of the features of ISO Standard C++ by translation to C, and except for exception handling, it typically results in object code with efficiency comparable to that of the code generated by a conventional C++ compiler.

Here are some products that perform compilation to C:

• Comeau Computing offers a compiler based on Edison Design Group's front end that outputs C code.
• LLVM is a downloadable compiler that emits C code. See also here and here. Here is an example of C++ to C conversion via LLVM.

• Cfront, the original implementation of C++, done by Bjarne Stroustrup and others at AT&T, generates C code. However it has two problems: it's been difficult to obtain a license since the mid 90s when it started going through a maze of ownership changes, and development ceased at that same time and so it doesn't get bug fixes and doesn't support any of the newer language features (e.g., exceptions, namespaces, RTTI, member templates).

• Contrary to popular myth, as of this writing there is no version of g++ that translates C++ to C. Such a thing seems to be doable, but I am not aware that anyone has actually done it (yet).

Note that you typically need to specify the target platform's CPU, OS and C compiler so that the generated C code will be specifically targeted for this platform. This means: (a) you probably can't take the C code generated for platform X and compile it on platform Y; and (b) it'll be difficult to do the translation yourself — it'll probably be a lot cheaper/safer with one of these tools.

One more time: do not email me saying these are just preprocessors — they are not — they are compilers.

Don't provide the handler to execute.

Get the HttpResponse object, use the handler to get the body and get the status code from it directly

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
    final HttpGet httpGet = new HttpGet(GET_URL);

    try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
        StatusLine statusLine = response.getStatusLine();
        System.out.println(statusLine.getStatusCode() + " " + statusLine.getReasonPhrase());
        String responseBody = EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8);
        System.out.println("Response body: " + responseBody);
    }
}

For quick single calls, the fluent API is useful:

Response response = Request.Get(uri)
        .connectTimeout(MILLIS_ONE_SECOND)
        .socketTimeout(MILLIS_ONE_SECOND)
        .execute();
HttpResponse httpResponse = response.returnResponse();
StatusLine statusLine = httpResponse.getStatusLine();

For older versions of java or httpcomponents, the code might look different.

It looks like details is an array of hashes. So item inside of your block will be the whole hash. Therefore, to check the :qty key, you'd do something like the following:

details.select{ |item| item[:qty] != "" }

That will give you all items where the :qty key isn't an empty string.

official select documentation

Using PDO:^[1]

$in = join(',', array_fill(0, count($ids), '?'));
$select = <<<SQL
    SELECT *
    FROM galleries
    WHERE id IN ($in);
SQL;
$statement = $pdo->prepare($select);
$statement->execute($ids);

Using MySQLi ^[2]

$in = join(',', array_fill(0, count($ids), '?'));
$select = <<<SQL
    SELECT *
    FROM galleries
    WHERE id IN ($in);
SQL;
$statement = $mysqli->prepare($select);
$statement->bind_param(str_repeat('i', count($ids)), ...$ids);
$statement->execute();
$result = $statement->get_result();

Explanation:

Use the SQL IN() operator to check if a value exists in a given list.

In general it looks like this:

expr IN (value,...)

We can build an expression to place inside the () from our array. Note that there must be at least one value inside the parenthesis or MySQL will return an error; this equates to making sure that our input array has at least one value. To help prevent against SQL injection attacks, first generate a ? for each input item to create a parameterized query. Here I assume that the array containing your ids is called $ids:

$in = join(',', array_fill(0, count($ids), '?'));

$select = <<<SQL
    SELECT *
    FROM galleries
    WHERE id IN ($in);
SQL;

Given an input array of three items $select will look like:

SELECT *
FROM galleries
WHERE id IN (?, ?, ?)

Again note that there is a ? for each item in the input array. Then we'll use PDO or MySQLi to prepare and execute the query as noted above.

Using the IN() operator with strings

It is easy to change between strings and integers because of the bound parameters. For PDO there is no change required; for MySQLi change str_repeat('i', to str_repeat('s', if you need to check strings.

^{[1]: I've omitted some error checking for brevity. You need to check for the usual errors for each database method (or set your DB driver to throw exceptions).}

^{[2]: Requires PHP 5.6 or higher. Again I've omitted some error checking for brevity.}

It's a magic number used in various places because it also happens to be readable in English, making it stand out. There's a partial list on Wikipedia.

Here is another way to use SQL SELECT statement in VBA:

 sSQL = "SELECT Variable FROM GroupTable WHERE VariableCode = '" & Me.comboBox & "'" 
 Set rs = CurrentDb.OpenRecordset(sSQL)
 On Error GoTo resultsetError 
 dbValue = rs!Variable
 MsgBox dbValue, vbOKOnly, "RS VALUE"
resultsetError:
 MsgBox "Error Retrieving value from database",VbOkOnly,"Database Error"

The problem is that jQuery doesn't trigger the native click event for <a> elements so that navigation doesn't happen (the normal behavior of an <a>), so you need to do that manually. For almost all other scenarios, the native DOM event is triggered (at least attempted to - it's in a try/catch).

To trigger it manually, try:

var a = $("<a>")
    .attr("href", "http://i.stack.imgur.com/L8rHf.png")
    .attr("download", "img.png")
    .appendTo("body");

a[0].click();

a.remove();

DEMO: http://jsfiddle.net/HTggQ/

Relevant line in current jQuery source: https://github.com/jquery/jquery/blob/1.11.1/src/event.js#L332

if ( (!special._default || special._default.apply( eventPath.pop(), data ) === false) &&
        jQuery.acceptData( elem ) ) {

This code works for me:

import groovy.io.FileType

def list = []

def dir = new File("path_to_parent_dir")
dir.eachFileRecurse (FileType.FILES) { file ->
  list << file
}

Afterwards the list variable contains all files (java.io.File) of the given directory and its subdirectories:

list.each {
  println it.path
}

I used purgatory101's answer but had trouble keeping all colours (icons, backgrounds, text colours etc...), especially that CSS stylesheets cannot be used with libraries which dynamically change DOM element's colours. Therefore here is a script that changes element's styles (background-colour and colour) before printing and clears styles once printing is done. It is useful to avoid writing a lot of CSS in a @media print stylesheet as it works whatever the page structure.

There is a part of the script that is specially made to keep FontAwesome icons color (or any element that uses a :before selector to insert coloured content).

JSFiddle showing the script in action

Compatibility: works in Chrome, I did not test other browsers.

function setColors(selector) {
  var elements = $(selector);
  for (var i = 0; i < elements.length; i++) {
    var eltBackground = $(elements[i]).css('background-color');
    var eltColor = $(elements[i]).css('color');

    var elementStyle = elements[i].style;
    if (eltBackground) {
      elementStyle.oldBackgroundColor = {
        value: elementStyle.backgroundColor,
        importance: elementStyle.getPropertyPriority('background-color'),
      };
      elementStyle.setProperty('background-color', eltBackground, 'important');
    }
    if (eltColor) {
      elementStyle.oldColor = {
        value: elementStyle.color,
        importance: elementStyle.getPropertyPriority('color'),
      };
      elementStyle.setProperty('color', eltColor, 'important');
    }
  }
}

function resetColors(selector) {
  var elements = $(selector);
  for (var i = 0; i < elements.length; i++) {
    var elementStyle = elements[i].style;

    if (elementStyle.oldBackgroundColor) {
      elementStyle.setProperty('background-color', elementStyle.oldBackgroundColor.value, elementStyle.oldBackgroundColor.importance);
      delete elementStyle.oldBackgroundColor;
    } else {
      elementStyle.setProperty('background-color', '', '');
    }
    if (elementStyle.oldColor) {
      elementStyle.setProperty('color', elementStyle.oldColor.value, elementStyle.oldColor.importance);
      delete elementStyle.oldColor;
    } else {
      elementStyle.setProperty('color', '', '');
    }
  }
}

function setIconColors(icons) {
  var css = '';
  $(icons).each(function (k, elt) {
    var selector = $(elt)
      .parents()
      .map(function () { return this.tagName; })
      .get()
      .reverse()
      .concat([this.nodeName])
      .join('>');

    var id = $(elt).attr('id');
    if (id) {
      selector += '#' + id;
    }

    var classNames = $(elt).attr('class');
    if (classNames) {
      selector += '.' + $.trim(classNames).replace(/\s/gi, '.');
    }

    css += selector + ':before { color: ' + $(elt).css('color') + ' !important; }';
  });
  $('head').append('<style id="print-icons-style">' + css + '</style>');
}

function resetIconColors() {
  $('#print-icons-style').remove();
}

And then modify the window.print function to make it set the styles before printing and resetting them after.

window._originalPrint = window.print;
window.print = function() {
  setColors('body *');
  setIconColors('body .fa');
  window._originalPrint();
  setTimeout(function () {
    resetColors('body *');
    resetIconColors();
  }, 100);
}

The part that finds icons paths to create CSS for :before elements is a copy from this SO answer

I had to reinstall eclipse, delete .m2 folder and rebuild the jars.

Tried suggested answers, but got it working only with this prefix approach:

npm i github:user/repo.git#version --save -D

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

You must have to define no-args or default constructor if you are creating your own constructor.

You can read why default or no argument constructor is required.

why-default-or-no-argument-constructor-java-class.html

Add the following style to your h3 elements:

word-wrap: break-word;

This will cause the long URLs in them to wrap. The default setting for word-wrap is normal, which will wrap only at a limited set of split tokens (e.g. whitespaces, hyphens), which are not present in a URL.

var label = $('#current_month');
var month = label.val('month');
var year = label.val('year');
var text = label.text();
alert(text);

<label year="2010" month="6" id="current_month"> June &nbsp;2010</label>

no.

BufferedReader.close()

closes the stream according to javadoc for BufferedReader and InputStreamReader

as well as

FileReader.close()

does.

I had a similar scenario, but was also required to set a Proxy. The simplest way I could see to do this was to extend the SimpleClientHttpRequestFactory for the ease of setting the proxy (different proxies for non-prod vs prod). This should still work even if you don't require the proxy though. Then in my extended class I override the openConnection(URL url, Proxy proxy) method, using the same as the source, but just setting the timeouts before returning.

@Override
protected HttpURLConnection openConnection(URL url, Proxy proxy) throws IOException {
    URLConnection urlConnection = proxy != null ? url.openConnection(proxy) : url.openConnection();
    Assert.isInstanceOf(HttpURLConnection.class, urlConnection);
    urlConnection.setConnectTimeout(5000);
    urlConnection.setReadTimeout(5000);
    return (HttpURLConnection) urlConnection;
}

I am guessing you're confused with the parameterization of the types:

// This works, because there is one class/type definition in the parameterized <> field
ArrayList<String> myArrayList = new ArrayList<String>(); 


// This doesn't work, as you cannot use primitive types here
ArrayList<char> myArrayList = new ArrayList<char>();

I know that this is quite old thing, but I solved issue like that: I had parent and child element was scrollable.

   if ($('#parent > *').length == 0 ){
        var wait = setInterval(function() {
            if($('#parent > *').length != 0 ) {
                $('#parent .child').bind('scroll',function() {
                  //do staff
                });
                clearInterval(wait);
            },1000);
        }

The issue I had is that I didn't know when the child is loaded to DOM, but I kept checking for it every second.

NOTE:this is useful if it happens soon but not right after document load, otherwise it will use clients computing power for no reason.

I recommend to use moment.js. Only providing date to moment will validate it, no need to pass the dateFormat.

var date = moment("2016-10-19");

And then date.isValid() gives desired result.

Se post HERE

Hover to the sidebar and select the "Restore visual elements of debugger..."

Try

data _null_; 
   monyy = '05May2013'; 
   date = input(substr(strip(monyy),1,9),date9.);
   put date=date9.; 
   run;

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

The following example shows how to use the range operator in a for loop to implement a foreach loop.

func PrintXml (out io.Writer, value interface{}) error {
    var data []byte
    var err error

    for _, action := range []func() {
        func () { data, err = xml.MarshalIndent(value, "", "  ") },
        func () { _, err = out.Write([]byte(xml.Header)) },
        func () { _, err = out.Write(data) },
        func () { _, err = out.Write([]byte("\n")) }} {
        action();
        if err != nil {
            return err
        }
    }
    return nil;
}

The example iterates over an array of functions to unify the error handling for the functions. A complete example is at Google´s playground.

PS: it shows also that hanging braces are a bad idea for the readability of code. Hint: the for condition ends just before the action() call. Obvious, isn't it?

In Kotlin,

You have to override getHeaders() method like :

val volleyEnrollRequest = object : JsonObjectRequest(GET_POST_PARAM, TARGET_URL, PAYLOAD_BODY_IF_YOU_WISH,
            Response.Listener {
                // Success Part  
            },

            Response.ErrorListener {
                // Failure Part
            }
        ) {
            // Providing Request Headers

            override fun getHeaders(): Map<String, String> {
               // Create HashMap of your Headers as the example provided below

                val headers = HashMap<String, String>()
                headers["Content-Type"] = "application/json"
                headers["app_id"] = APP_ID
                headers["app_key"] = API_KEY

                return headers
            }
        }

simply if you want to create any HTML tag you can try this for example

var selectBody = $('body');
var div = $('<div>');
var h1  = $('<h1>');
var p   = $('<p>');

if you want to add any element on the flay you can try this

selectBody.append(div);

you can access the children of a vuejs component with this.$children. if you want to use the query selector on the current component instance then this.$el.querySelector(...)

just doing a simple console.log(this) will show you all the properties of a vue component instance.

additionally if you know the element you want to access in your component, you can add the v-el:uniquename directive to it and access it via this.$els.uniquename

I had a similar issue, I was getting 400, Bad Request only with the PUT, where as POST request was perfectly fine.

Below code worked fine for POST but was giving BAD Request for PUT:

conn.setRequestProperty("Content-Type", "application/json");
os.writeBytes(json);

After making below changes worked fine for both POST and PUT

conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
os.write(json.getBytes("UTF-8"));

Misspellings are irritating, aren't they? Check your spelling of empty, but then also try this:

#!/bin/bash -e

if [ -s diff.txt ]
then
        rm -f empty.txt
        touch full.txt
else
        rm -f full.txt
        touch empty.txt
fi

I like shell scripting a lot, but one disadvantage of it is that the shell cannot help you when you misspell, whereas a compiler like your C++ compiler can help you.

Notice incidentally that I have swapped the roles of empty.txt and full.txt, as @Matthias suggests.

If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}" should do the trick.

I cracked open Reflector to have a look at this as there seems to be a bit of confusion about SortedList. It is in fact not a binary search tree, it is a sorted (by key) array of key-value pairs. There is also a TKey[] keys variable which is sorted in sync with the key-value pairs and used to binary search.

Here is some source (targeting .NET 4.5) to backup my claims.

Private members

// Fields
private const int _defaultCapacity = 4;
private int _size;
[NonSerialized]
private object _syncRoot;
private IComparer<TKey> comparer;
private static TKey[] emptyKeys;
private static TValue[] emptyValues;
private KeyList<TKey, TValue> keyList;
private TKey[] keys;
private const int MaxArrayLength = 0x7fefffff;
private ValueList<TKey, TValue> valueList;
private TValue[] values;
private int version;

SortedList.ctor(IDictionary, IComparer)

public SortedList(IDictionary<TKey, TValue> dictionary, IComparer<TKey> comparer) : this((dictionary != null) ? dictionary.Count : 0, comparer)
{
    if (dictionary == null)
    {
        ThrowHelper.ThrowArgumentNullException(ExceptionArgument.dictionary);
    }
    dictionary.Keys.CopyTo(this.keys, 0);
    dictionary.Values.CopyTo(this.values, 0);
    Array.Sort<TKey, TValue>(this.keys, this.values, comparer);
    this._size = dictionary.Count;
}

SortedList.Add(TKey, TValue) : void

public void Add(TKey key, TValue value)
{
    if (key == null)
    {
        ThrowHelper.ThrowArgumentNullException(ExceptionArgument.key);
    }
    int num = Array.BinarySearch<TKey>(this.keys, 0, this._size, key, this.comparer);
    if (num >= 0)
    {
        ThrowHelper.ThrowArgumentException(ExceptionResource.Argument_AddingDuplicate);
    }
    this.Insert(~num, key, value);
}

SortedList.RemoveAt(int) : void

public void RemoveAt(int index)
{
    if ((index < 0) || (index >= this._size))
    {
        ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument.index, ExceptionResource.ArgumentOutOfRange_Index);
    }
    this._size--;
    if (index < this._size)
    {
        Array.Copy(this.keys, index + 1, this.keys, index, this._size - index);
        Array.Copy(this.values, index + 1, this.values, index, this._size - index);
    }
    this.keys[this._size] = default(TKey);
    this.values[this._size] = default(TValue);
    this.version++;
}

Under Ubuntu I had the problem and solved it with

$ sudo apt-get install php5-mcrypt
$ sudo service apache2 reload

I suppose you want form based authentication using deployment descriptors and j_security_check.

You can also do this in JSF by just using the same predefinied field names j_username and j_password as demonstrated in the tutorial.

E.g.

<form action="j_security_check" method="post">
    <h:outputLabel for="j_username" value="Username" />
    <h:inputText id="j_username" />
    <br />
    <h:outputLabel for="j_password" value="Password" />
    <h:inputSecret id="j_password" />
    <br />
    <h:commandButton value="Login" />
</form>

You could do lazy loading in the User getter to check if the User is already logged in and if not, then check if the Principal is present in the request and if so, then get the User associated with j_username.

package com.stackoverflow.q2206911;

import java.io.IOException;
import java.security.Principal;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;

@ManagedBean
@SessionScoped
public class Auth {

    private User user; // The JPA entity.

    @EJB
    private UserService userService;

    public User getUser() {
        if (user == null) {
            Principal principal = FacesContext.getCurrentInstance().getExternalContext().getUserPrincipal();
            if (principal != null) {
                user = userService.find(principal.getName()); // Find User by j_username.
            }
        }
        return user;
    }

}

The User is obviously accessible in JSF EL by #{auth.user}.

To logout do a HttpServletRequest#logout() (and set User to null!). You can get a handle of the HttpServletRequest in JSF by ExternalContext#getRequest(). You can also just invalidate the session altogether.

public String logout() {
    FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
    return "login?faces-redirect=true";
}

For the remnant (defining users, roles and constraints in deployment descriptor and realm), just follow the Java EE 6 tutorial and the servletcontainer documentation the usual way.

Update: you can also use the new Servlet 3.0 HttpServletRequest#login() to do a programmatic login instead of using j_security_check which may not per-se be reachable by a dispatcher in some servletcontainers. In this case you can use a fullworthy JSF form and a bean with username and password properties and a login method which look like this:

<h:form>
    <h:outputLabel for="username" value="Username" />
    <h:inputText id="username" value="#{auth.username}" required="true" />
    <h:message for="username" />
    <br />
    <h:outputLabel for="password" value="Password" />
    <h:inputSecret id="password" value="#{auth.password}" required="true" />
    <h:message for="password" />
    <br />
    <h:commandButton value="Login" action="#{auth.login}" />
    <h:messages globalOnly="true" />
</h:form>

And this view scoped managed bean which also remembers the initially requested page:

@ManagedBean
@ViewScoped
public class Auth {

    private String username;
    private String password;
    private String originalURL;

    @PostConstruct
    public void init() {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        originalURL = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_REQUEST_URI);

        if (originalURL == null) {
            originalURL = externalContext.getRequestContextPath() + "/home.xhtml";
        } else {
            String originalQuery = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_QUERY_STRING);

            if (originalQuery != null) {
                originalURL += "?" + originalQuery;
            }
        }
    }

    @EJB
    private UserService userService;

    public void login() throws IOException {
        FacesContext context = FacesContext.getCurrentInstance();
        ExternalContext externalContext = context.getExternalContext();
        HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();

        try {
            request.login(username, password);
            User user = userService.find(username, password);
            externalContext.getSessionMap().put("user", user);
            externalContext.redirect(originalURL);
        } catch (ServletException e) {
            // Handle unknown username/password in request.login().
            context.addMessage(null, new FacesMessage("Unknown login"));
        }
    }

    public void logout() throws IOException {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        externalContext.invalidateSession();
        externalContext.redirect(externalContext.getRequestContextPath() + "/login.xhtml");
    }

    // Getters/setters for username and password.
}

This way the User is accessible in JSF EL by #{user}.

I'm not sure that I understand what you mean by "rights of ownership".

If User B owns a stored procedure, User B can grant User A permission to run the stored procedure

GRANT EXECUTE ON b.procedure_name TO a

User A would then call the procedure using the fully qualified name, i.e.

BEGIN
  b.procedure_name( <<list of parameters>> );
END;

Alternately, User A can create a synonym in order to avoid having to use the fully qualified procedure name.

CREATE SYNONYM procedure_name FOR b.procedure_name;

BEGIN
  procedure_name( <<list of parameters>> );
END;

Write-Host is terrible, a destroyer of worlds, yet you can use it just to display progress to a user whilst using Write-Output to log (not that the OP asked for logging).

Write-Output "Enabling feature XYZ" | Out-File "log.txt" # Pipe to log file
Write-Host -NoNewLine "Enabling feature XYZ......."
$result = Enable-SPFeature
$result | Out-File "log.txt"
# You could try{}catch{} an exception on Enable-SPFeature depending on what it's doing
if ($result -ne $null) {
    Write-Host "complete"
} else {
    Write-Host "failed"
}

You can implement a class that holds the fields you have in your JSON

class MyData
{
    public string t;
    public bool a;
    public object[] data;
    public string[][] type;
}

and then use the generic version of DeserializeObject:

MyData tmp = JsonConvert.DeserializeObject<MyData>(json);
foreach (string typeStr in tmp.type[0])
{
    // Do something with typeStr
}

There is some incorrect information in this thread. I copied and pasted the incorrect information:

LEFT OUTER JOIN

SELECT *
FROM A, B
WHERE A.column = B.column(+)

RIGHT OUTER JOIN

SELECT *
FROM A, B
WHERE B.column(+) = A.column

The above is WRONG!!!!! It's reversed. How I determined it's incorrect is from the following book:

Oracle OCP Introduction to Oracle 9i: SQL Exam Guide. Page 115 Table 3-1 has a good summary on this. I could not figure why my converted SQL was not working properly until I went old school and looked in a printed book!

Here is the summary from this book, copied line by line:

Oracle outer Join Syntax:

from tab_a a, tab_b b,                                       
where a.col_1 + = b.col_1                                     

ANSI/ISO Equivalent:

from tab_a a left outer join  
tab_b b on a.col_1 = b.col_1

Notice here that it's the reverse of what is posted above. I suppose it's possible for this book to have errata, however I trust this book more so than what is in this thread. It's an exam guide for crying out loud...

If you want to start afresh, deleting the settings.json file from your user's profile will do the trick.

But if you don't want to reset everything, it is still possible through settings menu.

You can search for the setting that you want to revert back using search box.

You will see some settings with the left blue line, it means you've modified that one.

If you take your cursor to that setting, a gear button will appear. You can click this to restore that setting.

You can also use the drop-down below that setting and change it to default.

Further to aduchis answer above - if you then need to filter based on those group by keys, you can define a class to wrap the many keys.

return customers.GroupBy(a => new CustomerGroupingKey(a.Country, a.Gender))
                .Where(a => a.Key.Country == "Ireland" && a.Key.Gender == "M")
                .SelectMany(a => a)
                .ToList();

Where CustomerGroupingKey takes the group keys:

    private class CustomerGroupingKey
    {
        public CustomerGroupingKey(string country, string gender)
        {
            Country = country;
            Gender = gender;
        }

        public string Country { get; }

        public string Gender { get; }
    }

This is a redirect solution with everything I wanted but could not find in a nice clean snippet to cut & paste.

This snippet has a number of advantages:

• lets you catch and retain any querystring params folks have on their url
• makes the link unqiue to avoid unwanted caching
• lets you inform users of the old and new site names
• shows a settable countdown
• can be used for deep-link redirects as retains params

How to use:

If you migrated an entire site then on the old server stop the original site and create another with this file as the default index.html file in the root folder. Edit the site settings so that any 404 error is redirected to this index.html page. This catches anyone who accesses the old site with a link into a sub-level page etc.

Now go to the opening script tag and edit the oldsite and newSite web addresses, and change the seconds value as needed.

Save and start your website. Job done - time for a coffee.

FWIW, I had this same error message under JSch 0.1.50. Upgrading to 0.1.52 solved the problem.

Kubernetes is an open source project that brings 'Google style' cluster management capabilities to the world of virtual machines, or 'on the metal' scenarios. It works very well with modern operating system environments (like CoreOS or Red Hat Atomic) that offer up lightweight computing 'nodes' that are managed for you. It is written in Golang and is lightweight, modular, portable and extensible. We (the Kubernetes team) are working with a number of different technology companies (including Mesosphere who curate the Mesos open source project) to establish Kubernetes as the standard way to interact with computing clusters. The idea is to reproduce the patterns that we see people needing to build cluster applications based on our experience at Google. Some of these concepts include:

• pods — a way to group containers together
• replication controllers — a way to handle the lifecycle of containers
• labels — a way to find and query containers, and
• services — a set of containers performing a common function.

So with Kubernetes alone you will have something that is simple, easy to get up-and-running, portable and extensible that adds 'cluster' as a noun to the things that you manage in the lightest weight manner possible. Run an application on a cluster, and stop worrying about an individual machine. In this case, cluster is a flexible resource just like a VM. It is a logical computing unit. Turn it up, use it, resize it, turn it down quickly and easily.

With Mesos, there is a fair amount of overlap in terms of the basic vision, but the products are at quite different points in their lifecycle and have different sweet spots. Mesos is a distributed systems kernel that stitches together a lot of different machines into a logical computer. It was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application run well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps. It is somewhat more heavy weight than the Kubernetes project, but is getting easier and easier to manage thanks to the work of folks like Mesosphere.

Now what gets really interesting is that Mesos is currently being adapted to add a lot of the Kubernetes concepts and to support the Kubernetes API. So it will be a gateway to getting more capabilities for your Kubernetes app (high availability master, more advanced scheduling semantics, ability to scale to a very large number of nodes) if you need them, and is well suited to run production workloads (Kubernetes is still in an alpha state).

When asked, I tend to say:

1. Kubernetes is a great place to start if you are new to the clustering world; it is the quickest, easiest and lightest way to kick the tires and start experimenting with cluster oriented development. It offers a very high level of portability since it is being supported by a lot of different providers (Microsoft, IBM, Red Hat, CoreOs, MesoSphere, VMWare, etc).

2. If you have existing workloads (Hadoop, Spark, Kafka, etc), Mesos gives you a framework that let's you interleave those workloads with each other, and mix in a some of the new stuff including Kubernetes apps.

3. Mesos gives you an escape valve if you need capabilities that are not yet implemented by the community in the Kubernetes framework.

array_key_exists will definitely tell you if a key exists in an array, whereas isset will only return true if the key/variable exists and is not null.

$a = array('key1' => '????', 'key2' => null);

isset($a['key1']);             // true
array_key_exists('key1', $a);  // true

isset($a['key2']);             // false
array_key_exists('key2', $a);  // true

There is another important difference: isset doesn't complain when $a does not exist, while array_key_exists does.

What I'm missing in the other answers is a reference to how this relates to co- and contravariance and sub- and supertypes (that is, polymorphism) in general and to Java in particular. This may be well understood by the OP, but just in case, here it goes:

Covariance

If you have a class Automobile, then Car and Truck are their subtypes. Any Car can be assigned to a variable of type Automobile, this is well-known in OO and is called polymorphism. Covariance refers to using this same principle in scenarios with generics or delegates. Java doesn't have delegates (yet), so the term applies only to generics.

I tend to think of covariance as standard polymorphism what you would expect to work without thinking, because:

List<Car> cars;
List<Automobile> automobiles = cars;
// You'd expect this to work because Car is-a Automobile, but
// throws inconvertible types compile error.

The reason of the error is, however, correct: List<Car> does not inherit from List<Automobile> and thus cannot be assigned to each other. Only the generic type parameters have an inherit relationship. One might think that the Java compiler simply isn't smart enough to properly understand your scenario there. However, you can help the compiler by giving him a hint:

List<Car> cars;
List<? extends Automobile> automobiles = cars;   // no error

Contravariance

The reverse of co-variance is contravariance. Where in covariance the parameter types must have a subtype relationship, in contravariance they must have a supertype relationship. This can be considered as an inheritance upper-bound: any supertype is allowed up and including the specified type:

class AutoColorComparer implements Comparator<Automobile>
    public int compare(Automobile a, Automobile b) {
        // Return comparison of colors
    }

This can be used with Collections.sort:

public static <T> void sort(List<T> list, Comparator<? super T> c)

// Which you can call like this, without errors:
List<Car> cars = getListFromSomewhere();
Collections.sort(cars, new AutoColorComparer());

You could even call it with a comparer that compares objects and use it with any type.

When to use contra or co-variance?

A bit OT perhaps, you didn't ask, but it helps understanding answering your question. In general, when you get something, use covariance and when you put something, use contravariance. This is best explained in an answer to Stack Overflow question How would contravariance be used in Java generics?.

So what is it then with List<? extends Map<String, String>>

You use extends, so the rules for covariance applies. Here you have a list of maps and each item you store in the list must be a Map<string, string> or derive from it. The statement List<Map<String, String>> cannot derive from Map, but must be a Map.

Hence, the following will work, because TreeMap inherits from Map:

List<Map<String, String>> mapList = new ArrayList<Map<String, String>>();
mapList.add(new TreeMap<String, String>());

but this will not:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new TreeMap<String, String>());

and this will not work either, because it does not satisfy the covariance constraint:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new ArrayList<String>());   // This is NOT allowed, List does not implement Map

What else?

This is probably obvious, but you may have already noted that using the extends keyword only applies to that parameter and not to the rest. I.e., the following will not compile:

List<? extends Map<String, String>> mapList = new List<? extends Map<String, String>>();
mapList.add(new TreeMap<String, Element>())  // This is NOT allowed

Suppose you want to allow any type in the map, with a key as string, you can use extend on each type parameter. I.e., suppose you process XML and you want to store AttrNode, Element etc in a map, you can do something like:

List<? extends Map<String, ? extends Node>> listOfMapsOfNodes = new...;

// Now you can do:
listOfMapsOfNodes.add(new TreeMap<Sting, Element>());
listOfMapsOfNodes.add(new TreeMap<Sting, CDATASection>());

If you haven't restarted your SQL database Server after you make login changes, then make sure you do that. Start->Programs->Microsoft SQL Server -> Configuration tools -> SQL Server configuration manager -> Restart Server.

It looks like you only added the user to the server. You need to add them to the database too. Either open the database/Security/User/Add New User or open the server/Security/Logins/Properties/User Mapping.

Just now I have this situation and I have tried this way which is very easy.

First stop your mysql service using this command:

service mysql stop

and then just again start your mysql service using this command

I hope it may help others... :)

As others have suggested, AirPlay mirroring is the way to go. To mirror directly to your computer use an AirPlay server like http://www.airserverapp.com/. Then, since it's showing up directly on your computer you can capture it using the built-in Quicktime app (File > New Screen Recording). Works great!

Guava provides the adapter you want as Int.asList(). There is an equivalent for each primitive type in the associated class, e.g., Booleans for boolean, etc.

int foo[] = {1,2,3,4,5,6,7,8,9,0};
Iterable<Integer> fooBar = Ints.asList(foo);
for(Integer i : fooBar) {
    System.out.println(i);
}

The suggestions above to use Arrays.asList won't work, even if they compile because you get an Iterator<int[]> rather than Iterator<Integer>. What happens is that rather than creating a list backed by your array, you created a 1-element list of arrays, containing your array.

The MAC address (the low-level local network interface address) does not survive hops through IP routers. You can't find the client MAC address from a remote server.

In a local subnet, the MAC addresses are mapped to IP addresses through the ARP system. Interfaces on the local net know how to map IP addresses to MAC addresses. However, when your packets have been routed on the local subnet to (and through) the gateway out to the "real" Internet, the originating MAC address is lost. Simplistically, each subnet-to-subnet hop of your packets involve the same sort of IP-to-MAC mapping for local routing in each subnet.

if you have ID or any specific field in your item, you can use filter(). its act like Where().

<a class="btn" ng-click="remove(item)">Delete</a>

in controller:

$scope.remove = function(item) { 
  $scope.bdays = $scope.bdays.filter(function (element) {
                    return element.ID!=item.ID
                });
}

To bootstrap 3.0.0:

.popover{ right:0!important; }

And modify too

.popover { max-width:WWWpx!important; } 

where WWW is your correct max-width to show your popover content.

A soft git reset will put committed changes back into your index. Next, checkout the branch you had intended to commit on. Then git commit with a new commit message.

1. git reset --soft <commit>

2. git checkout <branch>

3. git commit -m "Commit message goes here"

From git docs:

git reset [<mode>] [<commit>] This form resets the current branch head to and possibly updates the index (resetting it to the tree of ) and the working tree depending on . If is omitted, defaults to --mixed. The must be one of the following:

--soft Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

There is no such thing. You'll have to either write a loop using printf or puts, or write a function that copies the string count times into a new string.

Cast it back to its original type, which will be a DataRowView if you're binding a table, and you can then get the Id and Text from the appropriate columns:

foreach(object itemChecked in checkedListBox1.CheckedItems)
{
     DataRowView castedItem = itemChecked as DataRowView;
     string comapnyName = castedItem["CompanyName"];
     int? id = castedItem["ID"];
}

public Date saveDateWithoutTime(Date date) {
    Calendar calendar = Calendar.getInstance();

    calendar.setTime( date );
    calendar.set(Calendar.HOUR_OF_DAY, 0);
    calendar.set(Calendar.HOUR, 0);
    calendar.set(Calendar.MINUTE, 0);
    calendar.set(Calendar.SECOND, 0);
    calendar.set(Calendar.MILLISECOND, 0);

    return calendar.getTime();
}

This will help you to compare dates without considering the time.

As for #2, in my case it magically came to life after replacing

<body>

tag with

<h:body>

After having done several (simpler, to be honest) JSF projects, I couldn't remember of doing anything different setting it up now, and I got this kind of error for the first time. I was making a very basic login page (username, password, user Bean...) and set up everything like usual. The only difference I spotted is tags aforementioned. Maybe someone finds this useful.

Basically when you hit 'return' on a function the function will stop and will not continue your iteration, so what you need to do is put it all on a list and then add it as a children of a widget

you can do something like this:

  Widget getTextWidgets(List<String> strings)
  {
    List<Widget> list = new List<Widget>();
    for(var i = 0; i < strings.length; i++){
        list.add(new Text(strings[i]));
    }
    return new Row(children: list);
  }

or even better, you can use .map() operator and do something like this:

  Widget getTextWidgets(List<String> strings)
  {
    return new Row(children: strings.map((item) => new Text(item)).toList());
  }

Quick answer:

Doing list() around a generator expression is (almost) exactly equivalent to having [] brackets around it. So yeah, you can do

>>> list((x for x in string.letters if x in (y for y in "BigMan on campus")))

But you can just as well do

>>> [x for x in string.letters if x in (y for y in "BigMan on campus")]

Yes, that will turn the generator expression into a list comprehension. It's the same thing and calling list() on it. So the way to make a generator expression into a list is to put brackets around it.

Detailed explanation:

A generator expression is a "naked" for expression. Like so:

x*x for x in range(10)

Now, you can't stick that on a line by itself, you'll get a syntax error. But you can put parenthesis around it.

>>> (x*x for x in range(10))
<generator object <genexpr> at 0xb7485464>

This is sometimes called a generator comprehension, although I think the official name still is generator expression, there isn't really any difference, the parenthesis are only there to make the syntax valid. You do not need them if you are passing it in as the only parameter to a function for example:

>>> sorted(x*x for x in range(10))
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

Basically all the other comprehensions available in Python 3 and Python 2.7 is just syntactic sugar around a generator expression. Set comprehensions:

>>> {x*x for x in range(10)}
{0, 1, 4, 81, 64, 9, 16, 49, 25, 36}

>>> set(x*x for x in range(10))
{0, 1, 4, 81, 64, 9, 16, 49, 25, 36}

Dict comprehensions:

>>> dict((x, x*x) for x in range(10))
{0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81}

>>> {x: x*x for x in range(10)}
{0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81}

And list comprehensions under Python 3:

>>> list(x*x for x in range(10))
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

>>> [x*x for x in range(10)]
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

Under Python 2, list comprehensions is not just syntactic sugar. But the only difference is that x will under Python 2 leak into the namespace.

>>> x
9

While under Python 3 you'll get

>>> x
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'x' is not defined

This means that the best way to get a nice printout of the content of your generator expression in Python is to make a list comprehension out of it! However, this will obviously not work if you already have a generator object. Doing that will just make a list of one generator:

>>> foo = (x*x for x in range(10))
>>> [foo]
[<generator object <genexpr> at 0xb7559504>]

In that case you will need to call list():

>>> list(foo)
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

Although this works, but is kinda stupid:

>>> [x for x in foo]
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

The another solution is service volume, You can define a service volume and mount host's PostgreSQL Data directory in that volume. Check out the given compose file for details.

version: '2'
services:
  db:   
    image: postgres:9.6.1
    volumes:
      - "/var/lib/postgresql/data:/var/lib/postgresql/data" 
    ports:
      - "5432:5432"

By doing this, another PostgreSQL service will run under container but uses same data directory which host PostgreSQL service is using.

for some reason sharex was set to True so I turned it back to False and it worked fine.

df.plot(........,sharex=False)

Check out CORS enabled image from MDN. Basically you must have a server hosting images with the appropriate Access-Control-Allow-Origin header.

<IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
        <FilesMatch "\.(cur|gif|ico|jpe?g|png|svgz?|webp)$">
            SetEnvIf Origin ":" IS_CORS
            Header set Access-Control-Allow-Origin "*" env=IS_CORS
        </FilesMatch>
    </IfModule>
</IfModule>

You will be able to save those images to DOM Storage as if they were served from your domain otherwise you will run into security issue.

var img = new Image,
    canvas = document.createElement("canvas"),
    ctx = canvas.getContext("2d"),
    src = "http://example.com/image"; // insert image url here

img.crossOrigin = "Anonymous";

img.onload = function() {
    canvas.width = img.width;
    canvas.height = img.height;
    ctx.drawImage( img, 0, 0 );
    localStorage.setItem( "savedImageData", canvas.toDataURL("image/png") );
}
img.src = src;
// make sure the load event fires for cached images too
if ( img.complete || img.complete === undefined ) {
    img.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";
    img.src = src;
}

The array creation syntaxes in C# that are expressions are:

new int[3]
new int[3] { 10, 20, 30 }
new int[] { 10, 20, 30 }
new[] { 10, 20, 30 }

In the first one, the size may be any non-negative integral value and the array elements are initialized to the default values.

In the second one, the size must be a constant and the number of elements given must match. There must be an implicit conversion from the given elements to the given array element type.

In the third one, the elements must be implicitly convertible to the element type, and the size is determined from the number of elements given.

In the fourth one the type of the array element is inferred by computing the best type, if there is one, of all the given elements that have types. All the elements must be implicitly convertible to that type. The size is determined from the number of elements given. This syntax was introduced in C# 3.0.

There is also a syntax which may only be used in a declaration:

int[] x = { 10, 20, 30 };

The elements must be implicitly convertible to the element type. The size is determined from the number of elements given.

there isn't an all-in-one guide

I refer you to C# 4.0 specification, section 7.6.10.4 "Array Creation Expressions".

Or you can do

s = Character.toUpperCase(s.charAt(0)) + s.substring(1); 

The Java volatile modifier is an example of a special mechanism to guarantee that communication happens between threads. When one thread writes to a volatile variable, and another thread sees that write, the first thread is telling the second about all of the contents of memory up until it performed the write to that volatile variable.

Atomic operations are performed in a single unit of task without interference from other operations. Atomic operations are necessity in multi-threaded environment to avoid data inconsistency.

var jsonObj = {
    members: 
           {
            host: "hostName",
            viewers: 
            {
                user1: "value1",
                user2: "value2",
                user3: "value3"
            }
        }
}

var i;

for(i=4; i<=8; i++){
    var newUser = "user" + i;
    var newValue = "value" + i;
    jsonObj.members.viewers[newUser] = newValue ;

}

console.log(jsonObj);

If you'd like to set this globally for all users of a machine, you can create the following directory and file structures:

mkdir %windir%\Sun\Java\Deployment

Create a file deployment.config with the content:

deployment.system.config=file:///c:/windows/Sun/Java/Deployment/deployment.properties
deployment.system.config.mandatory=TRUE

Create a file deployment.properties

deployment.user.security.exception.sites=C\:/WINDOWS/Sun/Java/Deployment/exception.sites

Create a file exception.sites

http://example1.com
http://example2.com/path/to/specific/directory/

1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:

Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:

urn:oasis:names:tc:SAML:1.0:
urn:oasis:names:tc:SAML:1.1:
urn:oasis:names:tc:SAML:2.0:

With Firefox, I:

1. Downloaded and unpacked a version of Swagger.IO to C:\Swagger\
2. Created a folder called Definitions in C:\Swagger\dist
3. Copied my swagger.json definition file there, and
4. Entered "Definitions/MyDef.swagger.json" in the Explore box

Be careful of your slash directions!!

It seems you can drill down in folder structure but not up, annoyingly.

Font myFont = new Font ("Courier New", 1, 17);

The 17 represents the font size. Once you have that, you can put:

g.setFont (myFont);
g.drawString ("Hello World", 10, 10);

Taken from the NSString reference, you can use :

NSString *theFileName = [[string lastPathComponent] stringByDeletingPathExtension];

The lastPathComponent call will return thefile.ext, and the stringByDeletingPathExtension will remove the extension suffix from the end.

You can also do:

sqlite3 database.db -init dump.sql

Dump and restore a single table from .sql

Dump

mysqldump db_name table_name > table_name.sql

Dumping from a remote database

mysqldump -u <db_username> -h <db_host> -p db_name table_name > table_name.sql

For further reference:

http://www.abbeyworkshop.com/howto/lamp/MySQL_Export_Backup/index.html

Restore

mysql -u <user_name> -p db_name
mysql> source <full_path>/table_name.sql

or in one line

mysql -u username -p db_name < /path/to/table_name.sql

Dump and restore a single table from a compressed (.sql.gz) format

Dump

mysqldump db_name table_name | gzip > table_name.sql.gz

I was facing same issue and it was because of my app notification icon was not flat. For android version lollipop or even below lollipop your app notification icon should be flat, don't use icon with shadows etc.

Below is the code that worked perfectly fine on all android versions.

private void sendNotification(String msg) {

    NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent intent = new Intent(this, CheckOutActivity.class);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_notification)
            .setContentTitle(getString(R.string.app_name))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
            .setContentText(msg).setLights(Color.GREEN, 300, 300)
            .setVibrate(new long[] { 100, 250 })
            .setDefaults(Notification.DEFAULT_SOUND).setAutoCancel(true);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(new Random().nextInt(), mBuilder.build());
}

Wrong icon

Right Icon

Another option is to do another "git stash" of the local uncommitted changes, then combine the two git stashes. Unfortunately git seems to not have a way to easily combine two stashes. So one option is to create two .diff files and apply them both--at lest its not an extra commit and doesn't involve a ten step process :|

In my case above mentioned methods work fine with php but when i try to upload files with these methods in node.js then i have some problem. So instead of using $http({..,..,...}) use the normal jquery ajax.

For select file use this

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this)"/>

And in controller

$scope.uploadFile = function(element) {   
var data = new FormData();
data.append('file', $(element)[0].files[0]);
jQuery.ajax({
      url: 'brand/upload',
      type:'post',
      data: data,
      contentType: false,
      processData: false,
      success: function(response) {
      console.log(response);
      },
      error: function(jqXHR, textStatus, errorMessage) {
      alert('Error uploading: ' + errorMessage);
      }
 });   
};
