With the command:

sudo apt-get remove --purge mysql\*

you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).

You can list all installed mysql packages with the command:

sudo dpkg -l | grep -i mysql

For more cleanup of the package cache, you can use the command:

sudo apt-get clean

Also, remember to use the command:

sudo updatedb

Otherwise the "locate" command will display old data.

To install mysql again, use the following command:

sudo apt-get install libmysqlclient-dev mysql-client

This will install the mysql client, libmysql and its headers files.

To install the mysql server, use the command:

sudo apt-get install mysql-server

Sure, what do you want to use for the gid? a static value, PHP var, ...

A static value of 1234 could be like:

INSERT INTO courses (name, location, gid)
SELECT name, location, 1234
FROM courses
WHERE cid = $cid

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

*.json
!spec/*.json

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

Here's what I did:

• Extracted the files using WinRAR
• Made my changes to the extracted files
• Opened the original JAR file with WinRAR
• Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.

I just want to share what I did in Javascript. My idea is to have search directions; in grid it could be 8 directions, but search should be bi-directional so 8 / 2 = 4 directions. When a player does its move, the search starts from the location. It searches 4 different bi-directions until its value is different from the player's stone(O or X).

Per a bi-direction search, two values can be added but need to subtract one because starting point was duplicated.

getWin(x,y,value,searchvector) {
if (arguments.length==2) {
  var checkTurn = this.state.squares[y][x];
  var searchdirections = [[-1,-1],[0,-1],[1,-1],[-1,0]];
  return searchdirections.reduce((maxinrow,searchdirection)=>Math.max(this.getWin(x,y,checkTurn,searchdirection)+this.getWin(x,y,checkTurn,[-searchdirection[0],-searchdirection[1]]),maxinrow),0);
} else {
  if (this.state.squares[y][x]===value) {
    var result = 1;
    if (
      x+searchvector[0] >= 0 && x+searchvector[0] < 3 && 
      y+searchvector[1] >= 0 && y+searchvector[1] < 3
      ) result += this.getWin(x+searchvector[0],y+searchvector[1],value,searchvector);
    return result;
  } else {
    return 0;
  }
}

}

This function can be used with two parameters (x,y), which are coordinates of the last move. In initial execution, it calls four bi-direction searches recursively with 4 parameters. All results are returned as lengths and the function finally picks the maximum length among 4 search bi-directions.

CAUTION: ONLY FOR WINDOWS

I came across this problem today and all the answers mentioned here helped me, but I personally had to dig a lot to solve it. So let me help all others by putting out the solution to it in a very simple form:

1. Download the executable 64 bit (32-bit if your computer is of 32 bit) exe from here.

   (Name of the file would be tesseract-ocr-w64-setup-v5.0.0.20190526 (alpha))

2. Install it. Let it install itself in the default C directory.

3. Now go to your Environment variable (Reach there by just searching it in the start menu or Go to Control Panel > System > Advanced System Settings > Environment Variables)

a) Select PATH and then Edit it. Click on NEW and add the path where it is installed (Usually C:\Program Files\Tesseract-OCR\)

Now you will not get the error!

You can use the ?? operator to set the default value but first you must set the Nullable property to true in your dbml file in the required field (xx.Online)

var hht = from x in db.HandheldAssets
        join a in db.HandheldDevInfos on x.AssetID equals a.DevName into DevInfo
        from aa in DevInfo.DefaultIfEmpty()
        select new
        {
        AssetID = x.AssetID,
        Status = xx.Online ?? false
        };

Following solution also provide array of subset which provide specific sum (here sum = 9)

array = [1, 3, 4, 2, 7, 8, 9]

(0..array.size).map { |i| array.combination(i).to_a.select { |a| a.sum == 9 } }.flatten(1)

return array of subsets which return sum of 9

 => [[9], [1, 8], [2, 7], [3, 4, 2]] 

If you happen to apply migrations already this may fix it.

Go to your Web.config and update your connection string based on your migration files.

Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-GigHub-201802102244201.mdf;Initial Catalog=aspnet-GigHub-201802102244201;

The datestrings should match the first numbers on your Migrations.

none of all above answers working good on my app

here is my working code

on your exit button:

Intent intent = new Intent(getApplicationContext(), MainActivity.class);
ComponentName cn = intent.getComponent();
Intent mainIntent = IntentCompat.makeRestartActivityTask(cn);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
mainIntent.putExtra("close", true);
startActivity(mainIntent);
finish();

that code is to close any other activity and bring MainActivity on top now on your MainActivity:

if( getIntent().getBooleanExtra("close", false)){
    finish();
}

try this ugly but workable solution:

// use CommonJS to export all keys
module.exports = { a: 1, b: 2, c: 3 };

// import by key
import { a, b, c } from 'commonjs-style-module';
console.log(a, b, c);

The rvest along with xml2 is another popular package for parsing html web pages.

library(rvest)
theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
file<-read_html(theurl)
tables<-html_nodes(file, "table")
table1 <- html_table(tables[4], fill = TRUE)

The syntax is easier to use than the xml package and for most web pages the package provides all of the options ones needs.

I use this:

@Query("Select c from Registration c where lower(c.place) like lower(concat('%', concat(:place, '%')))")

lower() is like toLowerCase in String, so the result isn't case sensitive.

you make the use of the HTML Helper and have

    @using(Html.BeginForm())
    {
        Username: <input type="text" name="username" /> <br />
        Password: <input type="text" name="password" /> <br />
        <input type="submit" value="Login">
        <input type="submit" value="Create Account"/>
    }

or use the Url helper

<form method="post" action="@Url.Action("MyAction", "MyController")" >

Html.BeginForm has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:

@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    < ... >
}

If you don't specify any arguments, the Html.BeginForm() will create a POST form that points to your current controller and current action. As an example, let's say you have a controller called Posts and an action called Delete

public ActionResult Delete(int id)
{
   var model = db.GetPostById(id);
   return View(model);
}

[HttpPost]
public ActionResult Delete(int id)
{
    var model = db.GetPostById(id);
    if(model != null) 
        db.DeletePost(id);

    return RedirectToView("Index");
}

and your html page would be something like:

<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>

@using(Html.BeginForm())
{
    <input type="submit" class="btn btn-danger" value="Delete Post"/>
    <text>or</text>
    @Url.ActionLink("go to list", "Index")
}

If you attach your code as a text file and your recipient(s) have "show attachments inline" option set (I believe it's set by default), Outlook should not mangle your code but it will be copy/paste-able directly from email.

You can print some text by using SELECT command like that:

SELECT 'some text'

Result:

+-----------+
| some text |
+-----------+
| some text |
+-----------+
1 row in set (0.02 sec)

This should work:

$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`

h1 {
  font-weight: bold;
  color: #fff;
  font-size: 32px;
}

h2 {
  font-weight: bold;
  color: #fff;
  font-size: 24px;
}

Note that after color you can use a word (e.g. white), a hex code (e.g. #fff) or RGB (e.g. rgb(255,255,255)) or RGBA (e.g. rgba(255,255,255,0.3)).

Solved the issue for me :

    Range(Cells(1, 1), Cells(100, 1)).Select

    For Each xCell In Selection

    xCell.Value = CDate(xCell.Value)

    Next xCell

For proxy_upstream timeout, I tried the above setting but these didn't work.

Setting resolver_timeout worked for me, knowing it was taking 30s to produce the upstream timeout message. E.g. me.atwibble.com could not be resolved (110: Operation timed out).

The solution to "Cannot Get /" can usually be determined if you do an "ng build" in the command line. You will find most often that one of your "imports" does not have the correct path.

As per my understanding you want data in dictionary as shown below:

key1: value1-1,value1-2,value1-3....value100-1
key2: value2-1,value2-2,value2-3....value100-2
key3: value3-1,value3-2,value3-2....value100-3

for this you can use list for each dictionary keys:

case_list = {}
for entry in entries_list:
    if key in case_list:
        case_list[key1].append(value)
    else:
        case_list[key1] = [value]

r = ("1"+"2"+"3")           // step1 | build string ==> "123"
r = +r                      // step2 | to number    ==> 123
r = r+100                   // step3 | +100         ==> 223
r = ""+r                    // step4 | to string    ==> "223"

//in one line
r = ""+(+("1"+"2"+"3")+100);

The only difference is the order of operations between the increment of the variable and the value the operator returns.

This code and its output explains the the difference:

#include<stdio.h>

int main(int argc, char* argv[])
{
  unsigned int i=0, a;
  printf("i initial value: %d; ", i);
  a = i++;
  printf("value returned by i++: %d, i after: %d\n", a, i);
  i=0;
  printf("i initial value: %d; ", i);
  a = ++i;
  printf(" value returned by ++i: %d, i after: %d\n",a, i);
}

The output is:

i initial value: 0; value returned by i++: 0, i after: 1
i initial value: 0;  value returned by ++i: 1, i after: 1

So basically ++i returns the value after it is incremented, while i++ return the value before it is incremented. At the end, in both cases the i will have its value incremented.

Another example:

#include<stdio.h>

int main ()
  int i=0;
  int a = i++*2;
  printf("i=0, i++*2=%d\n", a);
  i=0;
  a = ++i * 2;
  printf("i=0, ++i*2=%d\n", a);
  i=0;
  a = (++i) * 2;
  printf("i=0, (++i)*2=%d\n", a);
  i=0;
  a = (++i) * 2;
  printf("i=0, (++i)*2=%d\n", a);
  return 0;
}

Output:

i=0, i++*2=0
i=0, ++i*2=2
i=0, (++i)*2=2
i=0, (++i)*2=2

Many times there is no difference

Differences are clear when the returned value is assigned to another variable or when the increment is performed in concatenation with other operations where operations precedence is applied (i++*2 is different from ++i*2, but (i++)*2 and (++i)*2 returns the same value) in many cases they are interchangeable. A classical example is the for loop syntax:

for(int i=0; i<10; i++)

has the same effect of

for(int i=0; i<10; ++i)

Rule to remember

To not make any confusion between the two operators I adopted this rule:

Associate the position of the operator ++ with respect to the variable i to the order of the ++ operation with respect to the assignment

Said in other words:

• ++ before i means incrementation must be carried out before assignment;
• ++ after i means incrementation must be carried out after assignment:

The $http service can be used for general purpose AJAX. If you have a proper RESTful API, you should take a look at ngResource.

You might also take a look at Restangular, which is a third party library to handle REST APIs easy.

This is how I implement singleton in my projects

Inspired from flutter firebase => FirebaseFirestore.instance.collection('collectionName')

class FooAPI {
  foo() {
    // some async func to api
  }
}

class SingletonService {
  FooAPI _fooAPI;

  static final SingletonService _instance = SingletonService._internal();

  static SingletonService instance = SingletonService();

  factory SingletonService() {
    return _instance;
  }

  SingletonService._internal() {
    // TODO: add init logic if needed
    // FOR EXAMPLE API parameters
  }

  void foo() async {
    await _fooAPI.foo();
  }
}

void main(){
  SingletonService.instance.foo();
}

example from my project

class FirebaseLessonRepository implements LessonRepository {
  FirebaseLessonRepository._internal();

  static final _instance = FirebaseLessonRepository._internal();

  static final instance = FirebaseLessonRepository();

  factory FirebaseLessonRepository() => _instance;

  var lessonsCollection = fb.firestore().collection('lessons');
  
  // ... other code for crud etc ...
}

// then in my widgets
FirebaseLessonRepository.instance.someMethod(someParams);

Some of these above answers didn't work for me but this did. Just in case someone else has the same issue.

I have encountered this problem And I solved it as follows: File->Sync Project with Gradle Files

good luck!

tl;dr

The modern approach uses java.time classes.

Instant.now()                                        // Capture current moment in UTC.
       .truncatedTo( ChronoUnit.SECONDS )            // Lop off any fractional second.
       .plus( 8 , ChronoUnit.HOURS )                 // Add eight hours.
       .atZone( ZoneId.of( "America/Montreal" ) )    // Adjust from UTC to the wall-clock time used by the people of a certain region (a time zone). Returns a `ZonedDateTime` object.
       .format(                                      // Generate a `String` object representing textually the value of the `ZonedDateTime` object.
           DateTimeFormatter.ofPattern( "dd/MM/uuuu HH:mm:ss" )
                            .withLocale( Locale.US ) // Specify a `Locale` to determine the human language and cultural norms used in localizing the text being generated. 
       )                                             // Returns a `String` object.

java.time

FYI, the old Calendar and Date classes are now legacy. Supplanted by the java.time classes. Much of java.time is back-ported to Java 6, Java 7, and Android (see below).

Instant

Capture the current moment in UTC with the Instant class.

Instant instantNow = Instant.now();

instant.toString(): 2017-01-23T12:34:56.789Z

If you want only whole seconds, without any fraction of a second, truncate.

Instant instant = instantNow.truncatedTo( ChronoUnit.SECONDS );

instant.toString(): 2017-01-23T12:34:56Z

Math

The Instant class can do math, adding an amount of time. Specify the amount of time to add by the ChronoUnit enum, an implementation of TemporalUnit.

instant = instant.plus( 8 , ChronoUnit.HOURS );

instant.toString(): 2017-01-23T20:34:56Z

ZonedDateTime

To see that same moment through the lens of a particular region’s wall-clock time, apply a ZoneId to get a ZonedDateTime.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

zdt.toString(): 2017-01-23T15:34:56-05:00[America/Montreal]

Generate string

You can generate a String in your desired format by specifying a formatting pattern in a DateTimeFormatter object.

Note that case matters in the letters of your formatting pattern. The Question’s code had hh which is for 12-hour time while uppercase HH is 24-hour time (0-23) in both java.time.DateTimeFormatter as well as the legacy java.text.SimpleDateFormat.

The formatting codes in java.time are similar to those in the legacy SimpleDateFormat but not exactly the same. Carefully study the class doc. Here, HH happens to work identically.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu HH:mm:ss" ).withLocale( Locale.US );
String output = zdt.format( f );

Automatic localization

Rather than hard-coding a formatting pattern, consider letting java.time fully localize the generation of the String text by calling DateTimeFormatter.ofLocalizedDateTime.

And, by the way, be aware that time zone and Locale have nothing to do with one another; orthogonal issues. One is about content, the meaning (the wall-clock time). The other is about presentation, determining the human language and cultural norms used in presenting that meaning to the user.

Instant instant = Instant.parse( "2017-01-23T12:34:56Z" );
ZoneId z = ZoneId.of( "Pacific/Auckland" );  // Notice that time zone is unrelated to the `Locale` used in localizing.
ZonedDateTime zdt = instant.atZone( z );

DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL )
                                       .withLocale( Locale.CANADA_FRENCH );  // The locale determines human language and cultural norms used in generating the text representing this date-time object.
String output = zdt.format( f );

instant.toString(): 2017-01-23T12:34:56Z

zdt.toString(): 2017-01-24T01:34:56+13:00[Pacific/Auckland]

output: mardi 24 janvier 2017 à 01:34:56 heure avancée de la Nouvelle-Zélande

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

Joda-Time

Update: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

Joda-Time makes this kind of work much easier.

// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;

DateTime later = DateTime.now().plusHours( 8 );
DateTimeFormatter formatter = DateTimeFormat.forPattern( "dd/MM/yyyy HH:mm:ss" );
String laterAsText = formatter.print( later );

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

When run…

laterAsText: 19/12/2013 02:50:18

Beware that this syntax uses default time zone. A better practice is to use an explicit DateTimeZone instance.

There are basically 4 types of main constraints in SQL:

• Domain Constraint: if one of the attribute values provided for a new tuple is not of the specified attribute domain

• Key Constraint: if the value of a key attribute in a new tuple already exists in another tuple in the relation

• Referential Integrity: if a foreign key value in a new tuple references a primary key value that does not exist in the referenced relation

• Entity Integrity: if the primary key value is null in a new tuple

You can not send custom header when you want to establish WebSockets connection using JavaScript WebSockets API. You can use Subprotocols headers by using the second WebSocket class constructor:

var ws = new WebSocket("ws://example.com/service", "soap");

and then you can get the Subprotocols headers using Sec-WebSocket-Protocol key on the server.

There is also a limitation, your Subprotocols headers values can not contain a comma (,) !

I finished using this function:

onkeypress="if(event.which < 48 || event.which > 57 ) if(event.which != 8) return false;"

This works well in IE and Chrome, I don´t know why it´s not work well in firefox too, this function block the tab key in Firefox.

For the tab key works fine in firefox add this:

onkeypress="if(event.which < 48 || event.which > 57 ) if(event.which != 8) if(event.keyCode != 9) return false;"

Builtin types that don't have constructors in the built-in namespace (e.g. functions, generators, methods) are in the types module. You can use types.FunctionType in an isinstance call:

>>> import types
>>> types.FunctionType
<class 'function'>

>>> def f(): pass

>>> isinstance(f, types.FunctionType)
True
>>> isinstance(lambda x : None, types.FunctionType)
True

Note that this uses a very specific notion of "function" that is usually not what you need. For example, it rejects zip (technically a class):

>>> type(zip), isinstance(zip, types.FunctionType)
(<class 'type'>, False)

open (built-in functions have a different type):

>>> type(open), isinstance(open, types.FunctionType)
(<class 'builtin_function_or_method'>, False)

and random.shuffle (technically a method of a hidden random.Random instance):

>>> type(random.shuffle), isinstance(random.shuffle, types.FunctionType)
(<class 'method'>, False)

If you're doing something specific to types.FunctionType instances, like decompiling their bytecode or inspecting closure variables, use types.FunctionType, but if you just need an object to be callable like a function, use callable.

If You are working on Frontend Then Use:

$currentStore=Mage::app()->getStore(); 

If You have store id then use

$store=Mage::getmodel('core/store')->load($storeId);

In Java 8 and JUnit 5 (Jupiter) we can assert for exceptions as follows. Using org.junit.jupiter.api.Assertions.assertThrows

public static < T extends Throwable > T assertThrows(Class< T > expectedType, Executable executable)

Asserts that execution of the supplied executable throws an exception of the expectedType and returns the exception.

If no exception is thrown, or if an exception of a different type is thrown, this method will fail.

If you do not want to perform additional checks on the exception instance, simply ignore the return value.

@Test
public void itShouldThrowNullPointerExceptionWhenBlahBlah() {
    assertThrows(NullPointerException.class,
            ()->{
            //do whatever you want to do here
            //ex : objectName.thisMethodShoulThrowNullPointerExceptionForNullParameter(null);
            });
}

That approach will use the Functional Interface Executable in org.junit.jupiter.api.

Refer :

• http://junit.org/junit5/docs/current/user-guide/#writing-tests-assertions
• http://junit.org/junit5/docs/5.0.0-M2/api/org/junit/jupiter/api/Executable.html

Most likely, you have model which contains the same property twice. Perhaps you are using new to hide the base property.

Solution is to override the property or use another name.

If you share your model, we would be able to elaborate more.

Just wanted to add, that after you remove the package in question you might also need to check to see if it's listed in the list of packages in the following area and manually remove its listing:

Preferences>Package Settings>Package Control>Settings - User

{
    "auto_upgrade_last_run": null,
    "installed_packages":
    [
        "AdvancedNewFile",
        "Emmet",
        "Package Control",
        "SideBarEnhancements",
        "Sublimerge"
    ]
}

In my instance, my trial period for "Sublimerge" had run out and I would get a popup every time I would start Sublime Text 2 saying:

"The package specified, Sublimerge, is not available"

I would have to close the event window out before being able to do anything in ST2.

But in my case, even after successfully removing the package through package control, I still received a event window popup message telling me "Sublimerge" wasn't available. This didn't make any sense as I had successfully removed the package.

It wasn't until I found this "auto_upgrade_last_run" file and manually removed the "Sublimerge" entry and saved my edit, did the message go away.

You could start by using git merge --no-commit, and then edit the merge however you like i.e. by unstaging config.xml or any other file, then commit. I suspect you'd want to automate it further after that using hooks, but I think it'd be worth going through manually at least once.

If you uncheck the ADB Integration, you cannot use the debug any more.You may just restart the adb server, run

$adb kill-server
$adb start-server

in Terminal to restart the adb server without restarting the Android Studio. Then the emulator shows up.

I figured out what the issue was : missing quotes in the testEcho() parameter. This is how I got the call to work:

myWebView.loadUrl("javascript:testEcho('Hello World!')");

Well without converting the integer to a string you could make a funky loop:

var number = 20000;
var length = 0;
for(i = number; i > 1; ++i){
     ++length;
     i = Math.floor(i/10);
}

alert(length);?

Using inspiration from http://blog.neutrino.es/2012/git-copy-a-file-or-directory-from-another-repository-preserving-history/ , I created this Powershell function for doing the same, which has worked great for me so far:

# Migrates the git history of a file or directory from one Git repo to another.
# Start in the root directory of the source repo.
# Also, before running this, I recommended that $destRepoDir be on a new branch that the history will be migrated to.
# Inspired by: http://blog.neutrino.es/2012/git-copy-a-file-or-directory-from-another-repository-preserving-history/
function Migrate-GitHistory
{
    # The file or directory within the current Git repo to migrate.
    param([string] $fileOrDir)
    # Path to the destination repo
    param([string] $destRepoDir)
    # A temp directory to use for storing the patch file (optional)
    param([string] $tempDir = "\temp\migrateGit")

    mkdir $tempDir

    # git log $fileOrDir -- to list commits that will be migrated
    Write-Host "Generating patch files for the history of $fileOrDir ..." -ForegroundColor Cyan
    git format-patch -o $tempDir --root -- $fileOrDir

    cd $destRepoDir
    Write-Host "Applying patch files to restore the history of $fileOrDir ..." -ForegroundColor Cyan
    ls $tempDir -Filter *.patch  `
        | foreach { git am $_.FullName }
}

Usage for this example:

git clone project2
git clone project1
cd project1
# Create a new branch to migrate to
git checkout -b migrate-from-project2
cd ..\project2
Migrate-GitHistory "deeply\buried\java\source\directory\A" "..\project1"

After you've done this, you can re-organize the files on the migrate-from-project2 branch before merging it.

While invoking the mysql CLI, you can specify the database name through the -D option. From mysql --help:

-D, --database=name Database to use.

I use this command:

mysql -h <db_host> -u <user> -D <db_name> -p

This is a mismatch between assemblies: a DLL referenced from an assembly doesn't have a method signature that's expected.

Clean the solution, rebuild everything, and try again.

Also, be careful if this is a reference to something that's in the GAC; it could be that something somewhere is pointing to an incorrect version. Make sure (through the Properties of each reference) that the correct version is chosen or that Specific Version is set false.

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myEnumerable.ToList();

The difference between gcc and g++ are:

     gcc            |        g++
compiles c source   |   compiles c++ source

use g++ instead of gcc to compile you c++ source.

Fine then. You can use CSS word wrap property. Something like this :

td.test /* Give whatever class name you want */
{
width:11em; /* Give whatever width you want */
word-wrap:break-word;
}

Another example of compound primary keys are the usage of Association tables. Suppose you have a person table that contains a set of people and a group table that contains a set of groups. Now you want to create a many to many relationship on person and group. Meaning each person can belong to many groups. Here is what the table structure would look like using a compound primary key.

Create Table Person(
PersonID int Not Null,
FirstName varchar(50),
LastName varchar(50),
Constraint PK_Person PRIMARY KEY (PersonID))

Create Table Group (
GroupId int Not Null,
GroupName varchar(50),
Constraint PK_Group PRIMARY KEY (GroupId))

Create Table GroupMember (
GroupId int Not Null,
PersonId int Not Null,
CONSTRAINT FK_GroupMember_Group FOREIGN KEY (GroupId) References Group(GroupId),
CONSTRAINT FK_GroupMember_Person FOREIGN KEY (PersonId) References Person(PersonId),
CONSTRAINT PK_GroupMember PRIMARY KEY (GroupId, PersonID))

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

select cast(getdate() as time(0))

returns for example :- 15:19:43

replace getdate() with the date time you want to extract just time from!

exponent is a 1D array. This means that exponent[0] is a scalar, and exponent[0][i] is trying to access it as if it were an array.

Did you mean to say:

L = identity(len(l))
for i in xrange(len(l)):
    L[i][i] = exponent[i]

or even

L = diag(exponent)

?

// New date object from millis
Date date = new Date(millis);
// formattter 
SimpleDateFormat formatter= new SimpleDateFormat("HH:mm:ss.SSS");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
// Pass date object
String formatted = formatter.format(date );

See runnable example using input of 1200 ms.

This just works on React & React Native

const data = require('./data/photos.json');

console.log('[-- typeof data --]', typeof data); // object


const fotos = data.xs.map(item => {
    return { uri: item };
});

Add following at the bottom of your Info.plist

<key>ITSAppUsesNonExemptEncryption</key>
<false/>

Here's Microsoft's write up on using SET IDENTITY_INSERT, which might be helpful to others seeing this post if they, like me, found this post when trying to recreate deleted records while maintaining the original identity column value.

Here is an example to access response body using angular2 built in Response

import { Injectable } from '@angular/core';
import {Http,Response} from '@angular/http';

@Injectable()
export class SampleService {
  constructor(private http:Http) { }

  getData(){

    this.http.get(url)
   .map((res:Response) => (
       res.json() //Convert response to JSON
       //OR
       res.text() //Convert response to a string
   ))
   .subscribe(data => {console.log(data)})

  }
}

I know it's not the answer you want, but IMO the proposed solutions are not good (and your own way is). Why? Because they depend on the application state. In JavaFX, a control, a scene and a stage do not depend on each other. This means a control can live without being added to a scene and a scene can exist without being attached to a stage. And then, at a time instant t1, control can get attached to a scene and at instant t2, that scene can be added to a stage (and that explains why they are observable properties of each other).

So the approach that suggests getting the controller reference and invoking a method, passing the stage to it adds a state to your application. This means you need to invoke that method at the right moment, just after the stage is created. In other words, you need to follow an order now: 1- Create the stage 2- Pass this created stage to the controller via a method.

You cannot (or should not) change this order in this approach. So you lost statelessness. And in software, generally, state is evil. Ideally, methods should not require any call order.

So what is the right solution? There are two alternatives:

1- Your approach, in the controller listening properties to get the stage. I think this is the right approach. Like this:

pane.sceneProperty().addListener((observableScene, oldScene, newScene) -> {
    if (oldScene == null && newScene != null) {
        // scene is set for the first time. Now its the time to listen stage changes.
        newScene.windowProperty().addListener((observableWindow, oldWindow, newWindow) -> {
            if (oldWindow == null && newWindow != null) {
                // stage is set. now is the right time to do whatever we need to the stage in the controller.
                ((Stage) newWindow).maximizedProperty().addListener((a, b, c) -> {
                    if (c) {
                        System.out.println("I am maximized!");
                    }
                });
            }
        });
    }
});

2- You do what you need to do where you create the Stage (and that's not what you want):

Stage stage = new Stage();
stage.maximizedProperty().addListener((a, b, c) -> {
            if (c) {
                System.out.println("I am maximized!");
            }
        });
stage.setScene(someScene);
...

I had significant headaches with these methods before, I recommend you avoid any variant of UrlEncode, and instead use Uri.EscapeDataString - at least that one has a comprehensible behavior.

Let's see...

HttpUtility.UrlEncode(" ") == "+" //breaks ASP.NET when used in paths, non-
                                  //standard, undocumented.
Uri.EscapeUriString("a?b=e") == "a?b=e" // makes sense, but rarely what you
                                        // want, since you still need to
                                        // escape special characters yourself

But my personal favorite has got to be HttpUtility.UrlPathEncode - this thing is really incomprehensible. It encodes:

• " " ==> "%20"
• "100% true" ==> "100%%20true" (ok, your url is broken now)
• "test A.aspx#anchor B" ==> "test%20A.aspx#anchor%20B"
• "test A.aspx?hmm#anchor B" ==> "test%20A.aspx?hmm#anchor B" (note the difference with the previous escape sequence!)

It also has the lovelily specific MSDN documentation "Encodes the path portion of a URL string for reliable HTTP transmission from the Web server to a client." - without actually explaining what it does. You are less likely to shoot yourself in the foot with an Uzi...

In short, stick to Uri.EscapeDataString.

Request and response.

To understand the req, try out console.log(req);.

Yes, You can do it in a simple way. See below code of lines.

URL - http://localhost:8080/get/request/multiple/param/by/map?name='abc' & id='123'

 @GetMapping(path = "/get/request/header/by/map")
    public ResponseEntity<String> getRequestParamInMap(@RequestParam Map<String,String> map){
        // Do your business here 
        return new ResponseEntity<String>(map.toString(),HttpStatus.OK);
    } 

C does not have an implementation of for-each. When parsing an array as a point the receiver does not know how long the array is, thus there is no way to tell when you reach the end of the array. Remember, in C int* is a point to a memory address containing an int. There is no header object containing information about how many integers that are placed in sequence. Thus, the programmer needs to keep track of this.

However, for lists, it is easy to implement something that resembles a for-each loop.

for(Node* node = head; node; node = node.next) {
   /* do your magic here */
}

To achieve something similar for arrays you can do one of two things.

1. use the first element to store the length of the array.
2. wrap the array in a struct which holds the length and a pointer to the array.

The following is an example of such struct:

typedef struct job_t {
   int count;
   int* arr;
} arr_t;

Data in jQuery ajax() function accepts anonymous objects as its input, see documentation. So example of what you're looking for is:

dataString = {key: 'val', key2: 'val2'};
$.ajax({
        type: "POST",
        url: "script.php",
        data: dataString, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });

You may also write POST/GET query on your own, like key=val&key2=val2, but you'd have to handle escaping yourself which is impractical.

For API 21 (5.0) and later you can use the CameraManager API's

try {
    String desiredCameraId = null;
    for(String cameraId : mCameraIDsList) {
        CameraCharacteristics chars =  mCameraManager.getCameraCharacteristics(cameraId);
        List<CameraCharacteristics.Key<?>> keys = chars.getKeys();
        try {
            if(CameraCharacteristics.LENS_FACING_FRONT == chars.get(CameraCharacteristics.LENS_FACING)) {
               // This is the one we want.
               desiredCameraId = cameraId;
               break;
            }
        } catch(IllegalArgumentException e) {
            // This key not implemented, which is a bit of a pain. Either guess - assume the first one
            // is rear, second one is front, or give up.
        }
    }
}

With an updated VS Code you can do it in the following manner:

1. Hit (Ctrl+P) and type:

   ext install cpptools
   

2. Open a folder (Ctrl+K & Ctrl+O) and create a new file inside the folder with the extension .cpp (ex: hello.cpp):

3. Type in your code and hit save.

4. Hit (Ctrl+Shift+P and type, Configure task runner and then select other at the bottom of the list.

5. Create a batch file in the same folder with the name build.bat and include the following code to the body of the file:

   @echo off
   call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64     
   set compilerflags=/Od /Zi /EHsc
   set linkerflags=/OUT:hello.exe
   cl.exe %compilerflags% hello.cpp /link %linkerflags%
   

6. Edit the task.json file as follows and save it:

   {
   // See https://go.microsoft.com/fwlink/?LinkId=733558
   // for the documentation about the tasks.json format
   "version": "0.1.0",
   "command": "build.bat",
   "isShellCommand": true,
   //"args": ["Hello World"],
   "showOutput": "always"
   }
   

7. Hit (Ctrl+Shift+B to run Build task. This will create the .obj and .exe files for the project.

8. For debugging the project, Hit F5 and select C++(Windows).

9. In launch.json file, edit the following line and save the file:

   "program": "${workspaceRoot}/hello.exe",
   

10. Hit F5.

This is the best solution provided by Google Developers. Simply call this method in onResume of onCreate after initializing GoogleApiClient.

Note : This line of code automatic open the dialog box if Location is not on. This piece of line is used in Google Map also

 status.startResolutionForResult(

 PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);

parser.add_argument also has a switch required. You can use required=False. Here is a sample snippet with Python 2.7:

parser = argparse.ArgumentParser(description='get dir')
parser.add_argument('--dir', type=str, help='dir', default=os.getcwd(), required=False)
args = parser.parse_args()

It's easy, if your mailx command supports the -a (append header) option:

$ mailx -a 'Content-Type: text/html' -s "my subject" [email protected] < email.html

If it doesn't, try using sendmail:

# create a header file
$ cat mailheader
To: [email protected]
Subject: my subject
Content-Type: text/html

# send
$ cat mailheader email.html | sendmail -t

I prefer:

def g(x):
  y0 = x + 1
  y1 = x * 3
  y2 = y0 ** y3
  return {'y0':y0, 'y1':y1 ,'y2':y2 }

It seems everything else is just extra code to do the same thing.

You have to edit three files to set a permanent environment variable as follow:

• ~/.bashrc

  When you open any terminal window this file will be run. Therefore, if you wish to have a permanent environment variable in all of your terminal windows you have to add the following line at the end of this file:

  export DISPLAY=0
  

• ~/.profile

  Same as bashrc you have to put the mentioned command line at the end of this file to have your environment variable in every login of your OS.

• /etc/environment

  If you want your environment variable in every window or application (not just terminal window) you have to edit this file. Add the following command at the end of this file:

  DISPLAY=0
  

  Note that in this file you do not have to write export command

Normally you have to restart your computer to apply these changes. But you can apply changes in bashrc and profile by these commands:

$ source ~/.bashrc
$ source ~/.profile

But for /etc/environment you have no choice but restarting (as far as I know)

A Simple Solution

I've written a simple script for these procedures to do all those work. You just have to set the name and value of your environment variable.

#!/bin/bash
echo "Enter variable name: "
read variable_name
echo "Enter variable value: "
read variable_value
echo "adding " $variable_name " to environment variables: " $variable_value
echo "export "$variable_name"="$variable_value>>~/.bashrc
echo $variable_name"="$variable_value>>~/.profile
echo $variable_name"="$variable_value>>/etc/environment
source ~/.bashrc
source ~/.profile
echo "do you want to restart your computer to apply changes in /etc/environment file? yes(y)no(n)"
read restart
case $restart in
    y) sudo shutdown -r 0;;
    n) echo "don't forget to restart your computer manually";;
esac
exit

Save these lines in a shfile then make it executable and just run it!

you can use -clean parameter while starting eclipse like

C:\eclipse\eclipse.exe -vm "C:\Program Files\Java\jdk1.6.0_24\bin" -clean

sudo ./script.sc

I also Suggest that if You want to see the Result in a file Like: Failure Occurs or Successful in backing-up, then Use the Command as Below:

sudo ./myshellsc.sh 2>> Backup-Report.log

Thank You.

Create an abstract method, and have each of your enumeration values override it. Since you know the opposite while you're creating it, there's no need to dynamically generate or create it.

It doesn't read nicely though; perhaps a switch would be more manageable?

public enum Direction {
    NORTH(1) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.SOUTH;
        }
    },
    SOUTH(-1) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.NORTH;
        }
    },
    EAST(-2) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.WEST;
        }
    },
    WEST(2) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.EAST;
        }
    };

    Direction(int code){
        this.code=code;
    }
    protected int code;

    public int getCode() {
        return this.code;
    }

    public abstract Direction getOppositeDirection();
}

I faced the same issue, It got fixed after keeping issuer subject value in the certificate as it is as subject of issuer certificate.

so please check "issuer subject value in the certificate(cert.pem) == subject of issuer (CA.pem)"

openssl verify -CAfile CA.pem cert.pem
cert.pem: OK

First option: invoke forEach indirectly

The parent.children is an Array like object. Use the following solution:

const parent = this.el.parentElement;

Array.prototype.forEach.call(parent.children, child => {
  console.log(child)
});

The parent.children is NodeList type, which is an Array like object because:

• It contains the length property, which indicates the number of nodes
• Each node is a property value with numeric name, starting from 0: {0: NodeObject, 1: NodeObject, length: 2, ...}

See more details in this article.

Second option: use the iterable protocol

parent.children is an HTMLCollection: which implements the iterable protocol. In an ES2015 environment, you can use the HTMLCollection with any construction that accepts iterables.

Use HTMLCollection with the spread operatator:

const parent = this.el.parentElement;

[...parent.children].forEach(child => {
  console.log(child);
});

Or with the for..of cycle (which is my preferred option):

const parent = this.el.parentElement;

for (const child of parent.children) {
  console.log(child);
}

You can do:

if not (u0 <= u <= u0+step):
    u0 = u0+ step # change the condition until it is satisfied
else:
    do sth. # condition is satisfied

Using a loop:

while not (u0 <= u <= u0+step):
   u0 = u0+ step # change the condition until it is satisfied
do sth. # condition is satisfied

You might implement your class model by composition, having the book object have a map of chapter objects contained within it (map chapter number to chapter object). Your search function could be given a list of books into which to search by asking each book to search its chapters. The book object would then iterate over each chapter, invoking the chapter.search() function to look for the desired key and return some kind of index into the chapter. The book's search() would then return some data type which could combine a reference to the book and some way to reference the data that it found for the search. The reference to the book could be used to get the name of the book object that is associated with the collection of chapter search hits.

On Mac OS X:

sudo find / -name postgresql.conf 

You can find other conf files by the following command:

sudo find / -name pg\*.conf

Note: See usage using man:

man find

You are encoding to UTF-8, then re-encoding to UTF-8. Python can only do this if it first decodes again to Unicode, but it has to use the default ASCII codec:

>>> u'ñ'
u'\xf1'
>>> u'ñ'.encode('utf8')
'\xc3\xb1'
>>> u'ñ'.encode('utf8').encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Don't keep encoding; leave encoding to UTF-8 to the last possible moment instead. Concatenate Unicode values instead.

You can use str.join() (or, rather, unicode.join()) here to concatenate the three values with dashes in between:

nombre = u'-'.join(fabrica, sector, unidad)
return nombre.encode('utf-8')

but even encoding here might be too early.

Rule of thumb: decode the moment you receive the value (if not Unicode values supplied by an API already), encode only when you have to (if the destination API does not handle Unicode values directly).

You can use either of the following ways listed below:

1. Use Env Inject Plugin for creating environment variables. Follow this for usage and more details https://github.com/jenkinsci/envinject-plugin
   2. Navigate below and can add

update the user table manually with your new password (note: feel free to type mysql> show tables; just to get a perspective on where you are)

NOTE: from MySQL 5.7 passwords are in the authenication_string table, so the command is update user set authentication_string=password('testpass') where user='root';

mysql> update user set password=PASSWORD("testpass") where User='root';

Solution for me:

1. BACK UP YOUR CODE!

2. Navigate to your project workspace (not your project) and run the following commands:

   dev1:workspace$ cd ~/Documents/workspace/.metadata/.plugins/ dev1:workspace$ rm -rf org.eclipse.core.resources

3. Navigate to your Eclipse directory and type this command:

   dev1:eclipse$ ./eclipse clear

4. Eclipse will start with an empty workspace - don't worry your projects are still there. Simple create new project from existing resource and things should be gravy.

Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed. It can contribute to efficiency in the program's operation if properly and appropriately used

Wikipedia

Link of Lazy Loading from hibernate.org

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

This should be

$endOfCycle=date('Y-m-d', strtotime("+30 days"));

strtotime

expects to be given a string containing a US English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.

while

date

Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.

If you have imported any files into project then check .m (main) file for same does exists in Targets (Project Name) -> Build Phases -> Compile Sources.

If file does not exists then include it using (+) Add button shown. Also, if duplicate files exists (if any) then delete it.

Now press cmd+shift+k to clean the project. New Build should not display this error.

Jon Skeet has written a library called morelinq which has a DistinctBy() operator. See here for the implementation. Your code would look like

IEnumerable<Note> distinctNotes = Notes.DistinctBy(note => note.Author);

Update: After re-reading your question, Kirk has the correct answer if you're just looking for a distinct set of Authors.

Added sample, several fields in DistinctBy:

res = res.DistinctBy(i => i.Name).DistinctBy(i => i.ProductId).ToList();

Use this SQL to get the first 2000 chars of the BLOB.

SELECT utl_raw.cast_to_varchar2(dbms_lob.substr(<YOUR_BLOB_FIELD>,2000,1)) FROM <YOUR_TABLE>;

Note: This is because, Oracle will not be able to handle the conversion of BLOB that is more than length 2000.

Edit #2 ( 7/2/2017)

If you install the angular cli right now, you'd probably have the new name of angular cli which is @angular/cli, so you need to uninstall it using

npm uninstall -g @angular/cli

and follow the code above. I'm still getting upvotes for this so I updated my answer for those who want to use the older version for some reasons.

Edit #1

If you really want to create a new project with previous version of Angular using the cli, try to downgrade the angular-cli before the final release. Something like:

npm uninstall -g angular-cli
npm cache clean
npm install -g [email protected]

Initial

You can change the version of the angular in the package.json . I'm guessing you want to use older version of angular but I suggest you use the latest version. Using:

ng new app-name

will always use the latest version of angular.

There are two problems with this question:

Assuming you have a gray scale bitmap, you have two factors to consider:

1. For JPGS... what loss of quality is tolerable?
2. For pngs... what level of compression is tolerable? (Although for most things I've seen, you don't have that much of a choice, so this choice might be negligible.) For anybody thinking this question doesn't make sense: yes, you can change the amount of compression/number of passes attempted to compress; check out either Ifranview or some of it's plugins.

Answer those questions, and then you might be able to find your original answer.

I think you are looking for JAX-WS authentication in application level, not HTTP basic in server level. See following complete example :

Application Authentication with JAX-WS

On the web service client site, just put your “username” and “password” into request header.

Map<String, Object> req_ctx = ((BindingProvider)port).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WS_URL);

Map<String, List<String>> headers = new HashMap<String, List<String>>();
headers.put("Username", Collections.singletonList("someUser"));
headers.put("Password", Collections.singletonList("somePass"));
req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);

On the web service server site, get the request header parameters via WebServiceContext.

@Resource
WebServiceContext wsctx;

@WebMethod
public String method() {
    MessageContext mctx = wsctx.getMessageContext();

    Map http_headers = (Map) mctx.get(MessageContext.HTTP_REQUEST_HEADERS);
    List userList = (List) http_headers.get("Username");
    List passList = (List) http_headers.get("Password");
    //...

        $("body").append(tempElem);

        tempElem.val(text).select();

'Simple HTML DOM Parser' is a good option for PHP, if your familiar with jQuery or JavaScript selectors then you will find yourself at home.

There is also a blog post about it here.

<xsl:call-template> is a close equivalent to calling a function in a traditional programming language.

You can define functions in XSLT, like this simple one that outputs a string.

<xsl:template name="dosomething">
  <xsl:text>A function that does something</xsl:text>
</xsl:template>

This function can be called via <xsl:call-template name="dosomething">.

<xsl:apply-templates> is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:

<!-- sample XML snippet -->
<xml>
  <foo /><bar /><baz />
</xml>

<!-- sample XSLT snippet -->
<xsl:template match="xml">
  <xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>

<xsl:template match="foo"> <!-- will be called once -->
  <xsl:text>foo element encountered</xsl:text>
</xsl:template>

<xsl:template match="*"> <!-- will be called twice -->
  <xsl:text>other element countered</xsl:text>
</xsl:template>

This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.

If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.

You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).

A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates> the current node moves on with every iteration, whereas <xsl:call-template> does not change the current node. I.e. the . within a called template refers to the same node as the . in the calling template. This is not the case with apply-templates.

This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode and priority, the fact that templates can have both a name and a match. It also has an impact whether the template has been imported (<xsl:import>) or not. These are advanced uses and you can deal with them when you get there.

From the GCC 4.2.1 manual, section -fwhole-program:

Assume that the current compilation unit represents whole program being compiled. All public functions and variables with the exception of main and those merged by attribute externally_visible become static functions and in a affect gets more aggressively optimized by interprocedural optimizers. While this option is equivalent to proper use of static keyword for programs consisting of single file, in combination with option --combine this flag can be used to compile most of smaller scale C programs since the functions and variables become local for the whole combined compilation unit, not for the single source file itself.

Had the same issue, resolved by actually enabling the extension in the php.ini with the right file name. It was listed as php_pdo_mysql.so but the module name in /lib/php/modules was called just pdo_mysql.so

So just remove the "php_" prefix from the php.ini file and then restart the httpd service and it worked like a charm.

Please note that I'm using Arch and thus path names and services may be different depending on your distrubution.

Looks like the usual suspects like pdfsharp and migradoc are not able to do that (pdfsharp only if you have Acrobat (Reader) installed).

I found here

https://vishalsbsinha.wordpress.com/2014/05/06/how-to-programmatically-c-net-print-a-pdf-file-directly-to-the-printer/

code ready for copy/paste. It uses the default printer and from what I can see it doesn't even use any libraries, directly sending the pdf bytes to the printer. So I assume the printer also needs to support it, on one 10 year old printer I tested this it worked flawlessly.

Most other approaches - without commercial libraries or applications - require you to draw yourself in the printing device context. Doable but will take a while to figure it out and make it work across printers.

For multiple commits on the wrong branch

If, for you, it is just about 1 commit, then there are plenty of other easier resetting solutions available. For me, I had about 10 commits that I'd accidentally created on master branch instead of, let's call it target, and I did not want to lose the commit history.

What you could do, and what saved me was using this answer as a reference, using a 4 step process, which is -

1. Create a new temporary branch temp from master
2. Merge temp into the branch originally intended for commits, i.e. target
3. Undo commits on master
4. Delete the temporary branch temp.

Here are the above steps in details -

1. Create a new branch from the master (where I had accidentally committed a lot of changes)

   git checkout -b temp
   

   Note: -b flag is used to create a new branch
   Just to verify if we got this right, I'd do a quick git branch to make sure we are on the temp branch and a git log to check if we got the commits right.

2. Merge the temporary branch into the branch originally intended for the commits, i.e. target.
   First, switch to the original branch i.e. target (You might need to git fetch if you haven't)

   git checkout target
   

   Note: Not using -b flag
   Now, let's merge the temporary branch into the branch we have currently checkout out target

   git merge temp
   

   You might have to take care of some conflicts here, if there are. You can push (I would) or move on to the next steps, after successfully merging.

3. Undo the accidental commits on master using this answer as reference, first switch to the master

   git checkout master
   

   then undo it all the way back to match the remote using the command below (or to particular commit, using appropriate command, if you want)

   git reset --hard origin/master
   

   Again, I'd do a git log before and after just to make sure that the intended changes took effect.

4. Erasing the evidence, that is deleting the temporary branch. For this, first you need to checkout the branch that the temp was merged into, i.e. target (If you stay on master and execute the command below, you might get a error: The branch 'temp' is not fully merged), so let's

   git checkout target
   

   and then delete the proof of this mishap

   git branch -d temp
   

There you go.

});

function doSomething() {

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).

When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization can convert these complex objects into byte strings for such use. After the byte strings are transmitted, the receiver will have to recover the original object from the byte string. This is known as deserialization.

Say, you have an object:

{foo: [1, 4, 7, 10], bar: "baz"}

serializing into JSON will convert it into a string:

'{"foo":[1,4,7,10],"bar":"baz"}'

which can be stored or sent through wire to anywhere. The receiver can then deserialize this string to get back the original object. {foo: [1, 4, 7, 10], bar: "baz"}.

Here is what is going on.

First, the only global variables Python really has are module-scoped variables. You cannot make a variable that is truly global; all you can do is make a variable in a particular scope. (If you make a variable inside the Python interpreter, and then import other modules, your variable is in the outermost scope and thus global within your Python session.)

All you have to do to make a module-global variable is just assign to a name.

Imagine a file called foo.py, containing this single line:

X = 1

Now imagine you import it.

import foo
print(foo.X)  # prints 1

However, let's suppose you want to use one of your module-scope variables as a global inside a function, as in your example. Python's default is to assume that function variables are local. You simply add a global declaration in your function, before you try to use the global.

def initDB(name):
    global __DBNAME__  # add this line!
    if __DBNAME__ is None: # see notes below; explicit test for None
        __DBNAME__ = name
    else:
        raise RuntimeError("Database name has already been set.")

By the way, for this example, the simple if not __DBNAME__ test is adequate, because any string value other than an empty string will evaluate true, so any actual database name will evaluate true. But for variables that might contain a number value that might be 0, you can't just say if not variablename; in that case, you should explicitly test for None using the is operator. I modified the example to add an explicit None test. The explicit test for None is never wrong, so I default to using it.

Finally, as others have noted on this page, two leading underscores signals to Python that you want the variable to be "private" to the module. If you ever do an import * from mymodule, Python will not import names with two leading underscores into your name space. But if you just do a simple import mymodule and then say dir(mymodule) you will see the "private" variables in the list, and if you explicitly refer to mymodule.__DBNAME__ Python won't care, it will just let you refer to it. The double leading underscores are a major clue to users of your module that you don't want them rebinding that name to some value of their own.

It is considered best practice in Python not to do import *, but to minimize the coupling and maximize explicitness by either using mymodule.something or by explicitly doing an import like from mymodule import something.

EDIT: If, for some reason, you need to do something like this in a very old version of Python that doesn't have the global keyword, there is an easy workaround. Instead of setting a module global variable directly, use a mutable type at the module global level, and store your values inside it.

In your functions, the global variable name will be read-only; you won't be able to rebind the actual global variable name. (If you assign to that variable name inside your function it will only affect the local variable name inside the function.) But you can use that local variable name to access the actual global object, and store data inside it.

You can use a list but your code will be ugly:

__DBNAME__ = [None] # use length-1 list as a mutable

# later, in code:  
if __DBNAME__[0] is None:
    __DBNAME__[0] = name

A dict is better. But the most convenient is a class instance, and you can just use a trivial class:

class Box:
    pass

__m = Box()  # m will contain all module-level values
__m.dbname = None  # database name global in module

# later, in code:
if __m.dbname is None:
    __m.dbname = name

(You don't really need to capitalize the database name variable.)

I like the syntactic sugar of just using __m.dbname rather than __m["DBNAME"]; it seems the most convenient solution in my opinion. But the dict solution works fine also.

With a dict you can use any hashable value as a key, but when you are happy with names that are valid identifiers, you can use a trivial class like Box in the above.

Your URL:

$url = 'http://learner.com/learningphp.php?lid=1348';
$file_name = basename(parse_url($url, PHP_URL_PATH));
echo $file_name;

output: learningphp.php

In the first code block, you're never using the str parameter. Did you mean to say the following?

testFunc = function(str, callback) {
    $.ajax({
        type: 'POST',
        url: 'http://www.myurl.com',
        data: str,
        success: callback
    });
}

I agree with @maverik above, I prefer not to hide the details with a typedef. Especially when you are trying to understand what is going on. I also prefer to see everything instead of a partial code snippet. With that said, here is a malloc and free of a complex structure.

The code uses the ms visual studio leak detector so you can experiment with the potential leaks.

You've correctly diagnosed your problem, so good job. Once you call into your search code, the for loop just keeps right on going.

I'm a big fan of https://github.com/caolan/async, and it serves me well. Basically with it you'd end up with something like:

var async = require('async')
async.eachSeries(Object.keys(config), function (key, next){ 
  search(config[key].query, function(err, result) { // <----- I added an err here
    if (err) return next(err)  // <---- don't keep going if there was an error

    var json = JSON.stringify({
      "result": result
    });
    results[key] = {
      "result": result
    }
    next()    /* <---- critical piece.  This is how the forEach knows to continue to
                       the next loop.  Must be called inside search's callback so that
                       it doesn't loop prematurely.*/
  })
}, function(err) {
  console.log('iterating done');
}); 

I hope that helps!

@Override
public void onAttach(Context context) {

    Activity activity = context instanceof Activity ? (Activity) context : null;

It uses commas as separators. So you can either set sep="," or just use read.csv:

x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593      9

The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):

State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582

And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table with the default quote argument (but not read.csv):

01,089,24,033,MD,Prince George's County,13,30,1040

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

Use this...

var all_matches = your_string.match(re);
console.log(all_matches)

It will return an array of all matches...That would work just fine.... But remember it won't take groups in account..It will just return the full matches...

You can't do that if USER is defined as a quoted string.

But you can do that if USER is just JACK or QUEEN or Joker or whatever.

There are two tricks to use:

1. Token-splicing, where you combine an identifier with another identifier by just concatenating their characters. This allows you to compare against JACK without having to #define JACK to something
2. variadic macro expansion, which allows you to handle macros with variable numbers of arguments. This allows you to expand specific identifiers into varying numbers of commas, which will become your string comparison.

So let's start out with:

#define JACK_QUEEN_OTHER(u) EXPANSION1(ReSeRvEd_, u, 1, 2, 3)

Now, if I write JACK_QUEEN_OTHER(USER), and USER is JACK, the preprocessor turns that into EXPANSION1(ReSeRvEd_, JACK, 1, 2, 3)

Step two is concatenation:

#define EXPANSION1(a, b, c, d, e) EXPANSION2(a##b, c, d, e)

Now JACK_QUEEN_OTHER(USER) becomes EXPANSION2(ReSeRvEd_JACK, 1, 2, 3)

This gives the opportunity to add a number of commas according to whether or not a string matches:

#define ReSeRvEd_JACK x,x,x
#define ReSeRvEd_QUEEN x,x

If USER is JACK, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(x,x,x, 1, 2, 3)

If USER is QUEEN, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(x,x, 1, 2, 3)

If USER is other, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(ReSeRvEd_other, 1, 2, 3)

At this point, something critical has happened: the fourth argument to the EXPANSION2 macro is either 1, 2, or 3, depending on whether the original argument passed was jack, queen, or anything else. So all we have to do is pick it out. For long-winded reasons, we'll need two macros for the last step; they'll be EXPANSION2 and EXPANSION3, even though one seems unnecessary.

Putting it all together, we have these 6 macros:

#define JACK_QUEEN_OTHER(u) EXPANSION1(ReSeRvEd_, u, 1, 2, 3)
#define EXPANSION1(a, b, c, d, e) EXPANSION2(a##b, c, d, e)
#define EXPANSION2(a, b, c, d, ...) EXPANSION3(a, b, c, d)
#define EXPANSION3(a, b, c, d, ...) d
#define ReSeRvEd_JACK x,x,x
#define ReSeRvEd_QUEEN x,x

And you might use them like this:

int main() {
#if JACK_QUEEN_OTHER(USER) == 1
  printf("Hello, Jack!\n");
#endif
#if JACK_QUEEN_OTHER(USER) == 2
  printf("Hello, Queen!\n");
#endif
#if JACK_QUEEN_OTHER(USER) == 3
  printf("Hello, who are you?\n");
#endif
}

MSVC Update: You have to parenthesize slightly differently to make things also work in MSVC. The EXPANSION* macros look like this:

#define EXPANSION1(a, b, c, d, e) EXPANSION2((a##b, c, d, e))
#define EXPANSION2(x) EXPANSION3 x
#define EXPANSION3(a, b, c, d, ...) d

I describe here a problem that I faced when run npm install - the package does not appear in node_modules.

The issue was that the name value in package.json of installed package was different than the name of imported package (key in package.json of my project).

So if your installed project name is some-package (name value in its package.json) then in package.json of your project write: "some-package": "owner/some-repo#tag".

From what I have observed, git merge tends to keep the branches separate even after merging, whereas rebase then merge combines it into one single branch. The latter comes out much cleaner, whereas in the former, it would be easier to find out which commits belong to which branch even after merging.

A slight improvement using column name, IMHO:

    Private Sub GridView1_Init(sender As Object, e As System.EventArgs) Handles GridView1.Init
    For Each dcf As DataControlField In GridView1.Columns
        Select Case dcf.HeaderText.ToUpper
            Case "CBSELECT"
                dcf.Visible = Me.CheckBoxVisible
                dcf.HeaderText = "<small>Select</small>"
        End Select
    Next
End Sub

This allows control over multiple column. I initially use a 'technical' column name, matching the control name within. This makes it obvious within the ASCX page that it's a control column. Then swap out the name as desired for presentation. If I spy the odd name in production, I know I skipped something. The "ToUpper" avoids case-issues.

Finally, this runs ONE time on any post instead of capturing the event during row-creation.

On the "edit" page, instead of including your CSS in the normal way (with a <link> tag), write it all to a <style> tag. Editing the innerHTML property of that will automatically update the page, even without a round-trip to the server.

<style type="text/css" id="styles">
    p {
        color: #f0f;
    }
</style>

<textarea id="editor"></textarea>
<button id="preview">Preview</button>

The Javascript, using jQuery:

jQuery(function($) {
    var $ed = $('#editor')
      , $style = $('#styles')
      , $button = $('#preview')
    ;
    $ed.val($style.html());
    $button.click(function() {
        $style.html($ed.val());
        return false;
    });
});

And that should be it!

If you wanted to be really fancy, attach the function to the keydown on the textarea, though you could get some unwanted side-effects (the page would be changing constantly as you type)

Edit: tested and works (in Firefox 3.5, at least, though should be fine with other browsers). See demo here: http://jsbin.com/owapi

There are no disadvantages of primary keys.

To add just some information to @MrWiggles and @Peter Parker answers, when table doesn't have primary key for example you won't be able to edit data in some applications (they will end up saying sth like cannot edit / delete data without primary key). Postgresql allows multiple NULL values to be in UNIQUE column, PRIMARY KEY doesn't allow NULLs. Also some ORM that generate code may have some problems with tables without primary keys.

UPDATE:

As far as I know it is not possible to replicate tables without primary keys in MSSQL, at least without problems (details).

With countries, languages or currency you may use emojis.

Works with pretty much every browser/OS that supports the use of emojis.

Refining the answer above, you can get 1-line syntax like you can for aliases, which is more convenient for ad-hoc definitions in a shell or .bashrc files:

bash$ myfunction() { mv "$1" "$1.bak" && cp -i "$2" "$1"; }

bash$ myfunction original.conf my.conf

Don't forget the semi-colon before the closing right-bracket. Similarly, for the actual question:

csh% alias junk="mv \\!* ~/.Trash"

bash$ junk() { mv "$@" ~/.Trash/; }

Or:

bash$ junk() { for item in "$@" ; do echo "Trashing: $item" ; mv "$item" ~/.Trash/; done; }

Using combining anonymous functions and Array.map for a cleaner; more streamlined look.

async and defer will download the file during HTML parsing. Both will not interrupt the parser.

• The script with async attribute will be executed once it is downloaded. While the script with defer attribute will be executed after completing the DOM parsing.

• The scripts loaded with async doesn't guarantee any order. While the scripts loaded with defer attribute maintains the order in which they appear on the DOM.

Use <script async> when the script does not rely on anything. when the script depends use <script defer>.

Best solution would be add the <script> at the bottom of the body. There will be no issue with blocking or rendering.

As far as I understand, you have more than one form tag in your web page that causes the problem. Make sure you have only one server-side form tag for each page.

Or you can use the ItemDataBound event in the code behind.

Database tables

To demonstrate how the USING and ON clauses work, let's assume we have the following post and post_comment database tables, which form a one-to-many table relationship via the post_id Foreign Key column in the post_comment table referencing the post_id Primary Key column in the post table:

The parent post table has 3 rows:

| post_id | title     |
|---------|-----------|
| 1       | Java      |
| 2       | Hibernate |
| 3       | JPA       |

and the post_comment child table has the 3 records:

| post_comment_id | review    | post_id |
|-----------------|-----------|---------|
| 1               | Good      | 1       |
| 2               | Excellent | 1       |
| 3               | Awesome   | 2       |

The JOIN ON clause using a custom projection

Traditionally, when writing an INNER JOIN or LEFT JOIN query, we happen to use the ON clause to define the join condition.

For example, to get the comments along with their associated post title and identifier, we can use the following SQL projection query:

SELECT
   post.post_id,
   title,
   review
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

And, we get back the following result set:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The JOIN USING clause using a custom projection

When the Foreign Key column and the column it references have the same name, we can use the USING clause, like in the following example:

SELECT
  post_id,
  title,
  review
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

And, the result set for this particular query is identical to the previous SQL query that used the ON clause:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The USING clause works for Oracle, PostgreSQL, MySQL, and MariaDB. SQL Server doesn't support the USING clause, so you need to use the ON clause instead.

The USING clause can be used with INNER, LEFT, RIGHT, and FULL JOIN statements.

SQL JOIN ON clause with SELECT *

Now, if we change the previous ON clause query to select all columns using SELECT *:

SELECT *
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

We are going to get the following result set:

| post_id | title     | post_comment_id | review    | post_id |
|---------|-----------|-----------------|-----------|---------|
| 1       | Java      | 1               | Good      | 1       |
| 1       | Java      | 2               | Excellent | 1       |
| 2       | Hibernate | 3               | Awesome   | 2       |

As you can see, the post_id is duplicated because both the post and post_comment tables contain a post_id column.

SQL JOIN USING clause with SELECT *

On the other hand, if we run a SELECT * query that features the USING clause for the JOIN condition:

SELECT *
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

We will get the following result set:

| post_id | title     | post_comment_id | review    |
|---------|-----------|-----------------|-----------|
| 1       | Java      | 1               | Good      |
| 1       | Java      | 2               | Excellent |
| 2       | Hibernate | 3               | Awesome   |

You can see that this time, the post_id column is deduplicated, so there is a single post_id column being included in the result set.

Conclusion

If the database schema is designed so that Foreign Key column names match the columns they reference, and the JOIN conditions only check if the Foreign Key column value is equal to the value of its mirroring column in the other table, then you can employ the USING clause.

Otherwise, if the Foreign Key column name differs from the referencing column or you want to include a more complex join condition, then you should use the ON clause instead.

If you want to use arrays as arguments, the following code works in Rails 4:

query = Order.where(uuid: uuids, id: ids)
Order.where(query.where_values.map(&:to_sql).join(" OR "))
#=> Order Load (0.7ms)  SELECT "orders".* FROM "orders" WHERE ("orders"."uuid" IN ('5459eed8350e1b472bfee48375034103', '21313213jkads', '43ujrefdk2384us') OR "orders"."id" IN (2, 3, 4))

You could use:

Dim MyForm As New Form1
MyForm.Show()

or rather:

MyForm.ShowDialog()

to open the form as a dialog box to ensure that user interacts with the new form or closes it.

Most of the above suggestions technically aren't C++, they're C solutions.

Look into the use of std::stringstream.

cat file2 >> file1

The >> operator appends the output to the named file or creates the named file if it does not exist.

cat file1 file2 > file3

This concatenates two or more files to one. You can have as many source files as you need. For example,

cat *.txt >> newfile.txt

Update 20130902
In the comments eumiro suggests "don't try cat file1 file2 > file1." The reason this might not result in the expected outcome is that the file receiving the redirect is prepared before the command to the left of the > is executed. In this case, first file1 is truncated to zero length and opened for output, then the cat command attempts to concatenate the now zero-length file plus the contents of file2 into file1. The result is that the original contents of file1 are lost and in its place is a copy of file2 which probably isn't what was expected.

Update 20160919
In the comments tpartee suggests linking to backing information/sources. For an authoritative reference, I direct the kind reader to the sh man page at linuxcommand.org which states:

Before a command is executed, its input and output may be redirected using a special notation interpreted by the shell.

While that does tell the reader what they need to know it is easy to miss if you aren't looking for it and parsing the statement word by word. The most important word here being 'before'. The redirection is completed (or fails) before the command is executed.

In the example case of cat file1 file2 > file1 the shell performs the redirection first so that the I/O handles are in place in the environment in which the command will be executed before it is executed.

A friendlier version in which the redirection precedence is covered at length can be found at Ian Allen's web site in the form of Linux courseware. His I/O Redirection Notes page has much to say on the topic, including the observation that redirection works even without a command. Passing this to the shell:

$ >out

...creates an empty file named out. The shell first sets up the I/O redirection, then looks for a command, finds none, and completes the operation.

You can consider using memory-mapped files, via FileChannels .

Generally a lot faster for large files. There are performance trade-offs that could make it slower, so YMMV.

Related answer: Java NIO FileChannel versus FileOutputstream performance / usefulness

In C++, a constructor with only one required parameter is considered an implicit conversion function. It converts the parameter type to the class type. Whether this is a good thing or not depends on the semantics of the constructor.

For example, if you have a string class with constructor String(const char* s), that's probably exactly what you want. You can pass a const char* to a function expecting a String, and the compiler will automatically construct a temporary String object for you.

On the other hand, if you have a buffer class whose constructor Buffer(int size) takes the size of the buffer in bytes, you probably don't want the compiler to quietly turn ints into Buffers. To prevent that, you declare the constructor with the explicit keyword:

class Buffer { explicit Buffer(int size); ... }

That way,

void useBuffer(Buffer& buf);
useBuffer(4);

becomes a compile-time error. If you want to pass a temporary Buffer object, you have to do so explicitly:

useBuffer(Buffer(4));

In summary, if your single-parameter constructor converts the parameter into an object of your class, you probably don't want to use the explicit keyword. But if you have a constructor that simply happens to take a single parameter, you should declare it as explicit to prevent the compiler from surprising you with unexpected conversions.

Try this:

SELECT *
INTO #Temp
FROM 
(select * from tblorders where busidate ='2016-11-24' and locationID=12
) as X

Please use alias with x so it will not failed the script and result.

There are a several things you need to address to get it working

1. The name is wrong its not @ouput its @code
2. You need to set the parameter direction to Output.
3. Don't use AddWithValue since its not supposed to have a value just you Add.
4. Use ExecuteNonQuery if you're not returning rows

Try

SqlParameter output = new SqlParameter("@code", SqlDbType.Int);
output.Direction = ParameterDirection.Output;
cmd.Parameters.Add(output);
cmd.ExecuteNonQuery();
MessageBox.Show(output.Value.ToString());

Try /^(?:-?[1-9]\d*$)|(?:^0)$/.

It matches positive, negative numbers as well as zeros.

It doesn't match input like 00, -0, +0, -00, +00, 01.

You can get some information :

From Martin Fowler about Mock and Stub

Fake objects actually have working implementations, but usually take some shortcut which makes them not suitable for production

Stubs provide canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test. Stubs may also record information about calls, such as an email gateway stub that remembers the messages it 'sent', or maybe only how many messages it 'sent'.

Mocks are what we are talking about here: objects pre-programmed with expectations which form a specification of the calls they are expected to receive.

From xunitpattern:

Fake: We acquire or build a very lightweight implementation of the same functionality as provided by a component that the SUT depends on and instruct the SUT to use it instead of the real.

Stub : This implementation is configured to respond to calls from the SUT with the values (or exceptions) that will exercise the Untested Code (see Production Bugs on page X) within the SUT. A key indication for using a Test Stub is having Untested Code caused by the inability to control the indirect inputs of the SUT

Mock Object that implements the same interface as an object on which the SUT (System Under Test) depends. We can use a Mock Object as an observation point when we need to do Behavior Verification to avoid having an Untested Requirement (see Production Bugs on page X) caused by an inability to observe side-effects of invoking methods on the SUT.

Personally

I try to simplify by using : Mock and Stub. I use Mock when it's an object that returns a value that is set to the tested class. I use Stub to mimic an Interface or Abstract class to be tested. In fact, it doesn't really matter what you call it, they are all classes that aren't used in production, and are used as utility classes for testing.

If you are using Babel and React 17, you might need to add "runtime2: "automatic" to config.

     }]]

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

Here's two simple examples

> x <- letters[1:4]
> replace(x, 3, 'Z') #replacing 'c' by 'Z'
[1] "a" "b" "Z" "d"
> 
> y <- 1:10
> replace(y, c(4,5), c(20,30)) # replacing 4th and 5th elements by 20 and 30
 [1]  1  2  3 20 30  6  7  8  9 10

Notepad++ only has column editing. This is not completely the same as multiple cursors.

Sublime Text has a marvelous implementation of this, might be worth checking out...
It's a relatively new editor (2011) that is gaining popularity quite fast: http://www.google.com/trends/explore#q=Notepad%2B%2B%2C%20Sublime%20Text&cmpt=q

Edit: Apparently somewhere around Notepad++ version 6.x multi-cursor editing got added, but there are still a few more advanced features for it in Sublime, like "select next occurrence".

A DateTime object can be constructed with a specific value of ticks. Once you have determined the ticks value, you can do the following:

DateTime myDate = new DateTime(numberOfTicks);
String test = myDate.ToString("MMMM dd, yyyy");

you can put

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

at the top of your car.js file for it to work, or you can do what Raynos said to do.

Here is an alternative way to solve this using a DIV and the 'contenteditable' property:

HTML:

<div contenteditable = "true" class = "fluidInput" data-placeholder = ""></div>

CSS: (to give the DIV some dimensions and make it easier to see)

.fluidInput {

    display         : inline-block;
    vertical-align  : top;

    min-width       : 1em;
    height          : 1.5em;

    font-family     : Arial, Helvetica, sans-serif;
    font-size       : 0.8em;
    line-height     : 1.5em;

    padding         : 0px 2px 0px 2px;
    border          : 1px solid #aaa;
    cursor          : text;
}


.fluidInput * {

    display         : inline;

}


.fluidInput br  {

    display         : none;

}


.fluidInput:empty:before {

    content         : attr(data-placeholder);
    color           : #ccc;

}

Note: If you are planning on using this inside of a FORM element that you plan to submit, you will need to use Javascript / jQuery to catch the submit event so that you can parse the 'value' ( .innerHTML or .html() respectively) of the DIV.

You can use the following in the web module that produces the war:

<build>
  <finalName>bird</finalName>
 . . .
</build>

This leads to a file called bird.war to be created when goal "war:war" is used.

The essence is this:

1. You're calling 'append' on the parent
2. but you want to call 'show' on the new child

This works for me:

var new_item = $('<p>hello</p>').hide();
parent.append(new_item);
new_item.show('normal');

or:

$('<p>hello</p>').hide().appendTo(parent).show('normal');

I wanted to share one more important finding.

use of <%= variable => would result in cross-site scripting vulnerability. So its more safe to use <%- variable -> instead.

We had to replace <%= with <%- to prevent cross-site scripting attacks. Not sure, whether this will it have any impact on the performance

Redirecting Error Messages from Command Prompt: STDERR/STDOUT

Summary

When redirecting output from an application using the '>' symbol, error messages still print to the screen. This is because error messages are often sent to the Standard Error stream instead of the Standard Out stream.

Output from a console (Command Prompt) application or command is often sent to two separate streams. The regular output is sent to Standard Out (STDOUT) and the error messages are sent to Standard Error (STDERR). When you redirect console output using the ">" symbol, you are only redirecting STDOUT. In order to redirect STDERR you have to specify '2>' for the redirection symbol. This selects the second output stream which is STDERR.

Example

The command dir file.xxx (where file.xxx does not exist) will display the following output:

Volume in drive F is Candy Cane Volume Serial Number is 34EC-0876

File Not Found

If you redirect the output to the NUL device using dir file.xxx > nul, you will still see the error message part of the output, like this:

File Not Found

To redirect (only) the error message to NUL, use the following command:

dir file.xxx 2> nul

Or, you can redirect the output to one place, and the errors to another.

dir file.xxx > output.msg 2> output.err

You can print the errors and standard output to a single file by using the "&1" command to redirect the output for STDERR to STDOUT and then sending the output from STDOUT to a file:

dir file.xxx 1> output.msg 2>&1

Try this:

yAxis: {min: 0, max: 100}

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

Java EE is actually a collection of technologies and APIs for the Java platform designed to support "Enterprise" Applications which can generally be classed as large-scale, distributed, transactional and highly-available applications designed to support mission-critical business requirements.

In terms of what an employee is looking for in specific techs, it is quite hard to say, because the playing field has kept changing over the last five years. It really is about the class of problems that are being solved more than anything else. Transactions and distribution are key.

The easiest way to do this would be to use a filter.

You can either filter for any cells in column A that don't have a "-" and copy / paste, or (my more preferred method) filter for all cells that do have a "-" and then select all and delete - Once you remove the filter, you're left with what you need.

Hope this helps.

If you want to $broadcast use the $rootScope:

$scope.startScanner = function() {

    $rootScope.$broadcast('scanner-started');
}

And then to receive, use the $scope of your controller:

$scope.$on('scanner-started', function(event, args) {

    // do what you want to do
});

If you want you can pass arguments when you $broadcast:

$rootScope.$broadcast('scanner-started', { any: {} });

And then receive them:

$scope.$on('scanner-started', function(event, args) {

    var anyThing = args.any;
    // do what you want to do
});

I solved it by doing the following:

In Visual studio I went in Project -> Project Dependencies

I selected the XXX.Test solution and told it that it also depends on the XXX solution to make the post-build events in the XXX.Test solution not generate this error (exit with code 4).

For those using bootstrap 4 beta you can add max-width on your navbar link to have control on the size of your logo with img-fluid class on the image element.

If you want to create a simple hyperlink instead of the pin it button,

Change this:

http://pinterest.com/pin/create/button/?url=

To this:

http://pinterest.com/pin/create/link/?url=

So, a complete URL might simply look like this:

<a href="//pinterest.com/pin/create/link/?url=http%3A%2F%2Fwww.flickr.com%2Fphotos%2Fkentbrew%2F6851755809%2F&media=http%3A%2F%2Ffarm8.staticflickr.com%2F7027%2F6851755809_df5b2051c9_z.jpg&description=Next%20stop%3A%20Pinterest">Pin it</a>

There are actually two place where where mac os x serves website by default:

Best programmatically Understanding.

when syntax is {}then this is JsonObject

when syntax is [] then this is JsonArray

A JSONObject is a JSON-like object that can be represented as an element in the JSONArray. JSONArray can contain a (or many) JSONObject

Hope this will helpful to you !

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

More Reference

I ran into this same problem these days and maybe some more detail might be helpful to somebody else.

I was looking some security guidelines for REST APIs and crossed a very intriguing issue with json arrays. Check the link for details, but basically, you should wrap them within an Object as we already saw in this post question.

So, instead of:

  [
    {
      "name": "order1"
    },
    {
      "name": "order2"
    }
  ]

It's advisable that we always do:

  {
    "data": [
      {
        "name": "order1"
      },
      {
        "name": "order2"
      }
    ]
  }

This is pretty straight-forward when you doing a GET, but might give you some trouble if, instead, your trying to POST/PUT the very same json.

In my case, I had more than one GET that was a List and more than one POST/PUT that would receive the very same json.

So what I end up doing was to use a very simple Wrapper object for a List:

public class Wrapper<T> {
  private List<T> data;

  public Wrapper() {}

  public Wrapper(List<T> data) {
    this.data = data;
  }
  public List<T> getData() {
    return data;
  }
  public void setData(List<T> data) {
    this.data = data;
  }
}

Serialization of my lists were made with a @ControllerAdvice:

@ControllerAdvice
public class JSONResponseWrapper implements ResponseBodyAdvice<Object> {

  @Override
  public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
    return true;
  }

  @Override
  @SuppressWarnings("unchecked")
  public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {
    if (body instanceof List) {
      return new Wrapper<>((List<Object>) body);
    }
    else if (body instanceof Map) {
      return Collections.singletonMap("data", body);
    }  
    return body;
  }
}

So, all the Lists and Maps where wrapped over a data object as below:

  {
    "data": [
      {...}
    ]
  }

Deserialization was still default, just using de Wrapper Object:

@PostMapping("/resource")
public ResponseEntity<Void> setResources(@RequestBody Wrapper<ResourceDTO> wrappedResources) {
  List<ResourceDTO> resources = wrappedResources.getData();
  // your code here
  return ResponseEntity
           .ok()
           .build();
}

That was it! Hope it helps someone.

Note: tested with SpringBoot 1.5.5.RELEASE.

With C++11, the above would be possible for basic types as

class Foo {
public:  
  static constexpr int MEMBER = 1;  
};

The constexpr part creates a static expression as opposed to a static variable - and that behaves just like an extremely simple inline method definition. The approach proved a bit wobbly with C-string constexprs inside template classes, though.

Someone posted this link to the MDN in a comment, and I think it was very helpful. It describes things like ErrorTypes very thoroughly.

EvalError --- Creates an instance representing an error that occurs regarding the global function eval().

InternalError --- Creates an instance representing an error that occurs when an internal error in the JavaScript engine is thrown. E.g. "too much recursion".

RangeError --- Creates an instance representing an error that occurs when a numeric variable or parameter is outside of its valid range.

ReferenceError --- Creates an instance representing an error that occurs when de-referencing an invalid reference.

SyntaxError --- Creates an instance representing a syntax error that occurs while parsing code in eval().

TypeError --- Creates an instance representing an error that occurs when a variable or parameter is not of a valid type.

URIError --- Creates an instance representing an error that occurs when encodeURI() or decodeURI() are passed invalid parameters.

This is how we can join two Dataframes on same column names in PySpark.

df = df1.join(df2, ['col1','col2','col3'])

If you do printSchema() after this then you can see that duplicate columns have been removed.

I guess a little more convenient and structured way is to use Html helper. In your view it can be look like:

@{
 var htmlAttr = new Dictionary<string, object>();
 htmlAttr.Add("id", strElementId);
 if (!CSSClass.IsEmpty())
 {
   htmlAttr.Add("class", strCSSClass);
 }
}

@* ... *@

@Html.TextBox("somename", "", htmlAttr)

If this way will be useful for you i recommend to define dictionary htmlAttr in your model so your view doesn't need any @{ } logic blocks (be more clear).

AngularJS - Input number with 2 decimal places it could help... Filtering:

3. Set the regular expression to validate the input using ng-pattern. Here I want to accept only numbers with a maximum of 2 decimal places and with a dot separator.

<input type="number" name="myDecimal" placeholder="Decimal" ng-model="myDecimal | number : 2" ng-pattern="/^[0-9]+(\.[0-9]{1,2})?$/" step="0.01" />

Reading forward this was pointed on the next answer ng-model="myDecimal | number : 2".

• I just went to Properties -> Java Build Path -> Libraries and removed the blue entries starting with M2_REPO.

• After that, I could use Maven -> Update Project again

If you only want to change the font in the TEXTAREA then you only need to change the changeFont() function in the original code to:

function changeFont(_name) {
    document.getElementById("mytextarea").style.fontFamily = _name;
}

Then selecting a font will change on the font only in the TEXTAREA.

xsd.exe as mentioned by Marc Gravell. The fastest way to get up and running IMO.

Or if you need more flexibility/options :

xsd2code VS add-in (Codeplex)

', '.join(set_3)

The join is a string method, not a set method.
