Programs & Examples On #Build environment

Check your system environment variables after installing Python, python 3's directories should be first in your PATH variable, then python 2.

Whichever path variable matches first is the one Windows uses.

As always py -2 will launch python2 in this scenario.

This is how to open any file:

from os import path

filepath = '...' # your path
file = open(filepath, 'r')

just .idea/ works fine for me

There is a limitation in SQL Server (up till 2008 R2) that varchar(MAX) and nvarchar(MAX) (and several other types like text, ntext ) cannot be used in indices. You have 2 options:
1. Set a limited size on the key field ex. nvarchar(100)
2. Create a check constraint that compares the value with all the keys in the table. The condition is:

([dbo].[CheckKey]([key])=(1))

and [dbo].[CheckKey] is a scalar function defined as:

CREATE FUNCTION [dbo].[CheckKey]
(
    @key nvarchar(max)
)
RETURNS bit
AS
BEGIN
    declare @res bit
    if exists(select * from key_value where [key] = @key)
        set @res = 0
    else
        set @res = 1

    return @res
END

But note that a native index is more performant than a check constraint so unless you really can't specify a length, don't use the check constraint.

The content of the Manifest file in a JAR file created with version 1.0 of the Java Development Kit is the following.

Manifest-Version: 1.0

All the entries are as name-value pairs. The name of a header is separated from its value by a colon. The default manifest shows that it conforms to version 1.0 of the manifest specification. The manifest can also contain information about the other files that are packaged in the archive. Exactly what file information is recorded in the manifest will depend on the intended use for the JAR file. The default manifest file makes no assumptions about what information it should record about other files, so its single line contains data only about itself. Special-Purpose Manifest Headers

Depending on the intended role of the JAR file, the default manifest may have to be modified. If the JAR file is created only for the purpose of archival, then the MANIFEST.MF file is of no purpose. Most uses of JAR files go beyond simple archiving and compression and require special information to be in the manifest file. Summarized below are brief descriptions of the headers that are required for some special-purpose JAR-file functions

Applications Bundled as JAR Files: If an application is bundled in a JAR file, the Java Virtual Machine needs to be told what the entry point to the application is. An entry point is any class with a public static void main(String[] args) method. This information is provided in the Main-Class header, which has the general form:

Main-Class: classname

The value classname is to be replaced with the application's entry point.

Download Extensions: Download extensions are JAR files that are referenced by the manifest files of other JAR files. In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an extension for the purposes of that applet. Extensions may reference each other in the same way. Download extensions are specified in the Class-Path header field in the manifest file of an applet, application, or another extension. A Class-Path header might look like this, for example:

Class-Path: servlet.jar infobus.jar acme/beans.jar

With this header, the classes in the files servlet.jar, infobus.jar, and acme/beans.jar will serve as extensions for purposes of the applet or application. The URLs in the Class-Path header are given relative to the URL of the JAR file of the applet or application.

Package Sealing: A package within a JAR file can be optionally sealed, which means that all classes defined in that package must be archived in the same JAR file. A package might be sealed to ensure version consistency among the classes in your software or as a security measure. To seal a package, a Name header needs to be added for the package, followed by a Sealed header, similar to this:

Name: myCompany/myPackage/
Sealed: true

The Name header's value is the package's relative pathname. Note that it ends with a '/' to distinguish it from a filename. Any headers following a Name header, without any intervening blank lines, apply to the file or package specified in the Name header. In the above example, because the Sealed header occurs after the Name: myCompany/myPackage header, with no blank lines between, the Sealed header will be interpreted as applying (only) to the package myCompany/myPackage.

Package Versioning: The Package Versioning specification defines several manifest headers to hold versioning information. One set of such headers can be assigned to each package. The versioning headers should appear directly beneath the Name header for the package. This example shows all the versioning headers:

Name: java/util/
Specification-Title: "Java Utility Classes" 
Specification-Version: "1.2"
Specification-Vendor: "Sun Microsystems, Inc.".
Implementation-Title: "java.util" 
Implementation-Version: "build57"
Implementation-Vendor: "Sun Microsystems, Inc."

I had this problem, read the above answer and download the entityframework.ddl but found that it is alreadt referenced. So I added the namespace and problem was solved

using System.Data.Entity;

I am using Visual Studio 2010, SP1 installed

Another way would by to use another loc utility, like LocMetrics for instance.
It also lists many other loc tools. The integration with Eclipse wouldn't be always there (as it would be with Metrics2, which you can check out because it is a more recent version than Metrics), but at least those tools can reason in term of logical lines (computed by summing the terminal semicolons and terminal curly braces).
You can also check with eclipse-metrics is more adapted to what you expect.

I was wraped it with <> </> as a parent when I changed it to normal , div , its worked fine

This error (or warning in later versions) occurs because you are compiling against a Java Execution Environment. This shows up as JRE System library [CDC-1.0/Foundation-1.0] in the Build path of your Eclipse Java project. Such environments only expose the Java standard API instead of all the classes within the runtime. This means that the classes used to implement the Java standard API are not exposed.

You can allow access to these particular classes using access rules, you could configure Eclipse to use the JDK directly or you could disable the error. You would however be hiding a serious error as Sun internal classes shouldn't be used (see below for a short explanation).

Java contains a Base64 class in the standard API since Java 1.8. See below for an example how to use it:

Java 8 import statement:

import java.util.Base64;

Java 8 example code:

// create a byte array containing data (test)
byte[] binaryData = new byte[] { 0x64, 0x61, 0x74, 0x61 };
// create and configure encoder (using method chaining) 
Base64.Encoder base64Encoder = Base64.getEncoder().withoutPadding();
// encode to string (instead of a byte array containing ASCII)
String base64EncodedData = base64Encoder.encodeToString(binaryData);

// decode using a single statement (no reuse of decoder)
// NOTE the decoder won't fail because the padding is missing
byte[] base64DecodedData = Base64.getDecoder().decode(base64EncodedData);

If Java 8 is not available a library such as Apache Commons Codec or Guava should be used.

Sun internal classes shouldn't be used. Those classes are used to implement Java. They have got public methods to allow instantiation from other packages. A good build environment however should protect you from using them.

Using internal classes may break compatibility with future Java SE runtimes; the implementation and location of these classes can change at any time. It should be strongly discouraged to disable the error or warning (but the disabling of the error is suggested in previous answers, including the two top voted ones).

This is the only install that resolved the issue for me.

SQL 2008 r2 w/ office 2010 64bit: "2007 Office System Driver: Data Connectivity Components"

An explicit call to a parent class constructor is required any time the parent class lacks a no-argument constructor. You can either add a no-argument constructor to the parent class or explicitly call the parent class constructor in your child class.

Use this to get an accurate count for each connection pool (assuming each user/host process uses the same connection string)

SELECT 
DB_NAME(dbid) as DBName, 
COUNT(dbid) as NumberOfConnections,
loginame as LoginName, hostname, hostprocess
FROM
sys.sysprocesses with (nolock)
WHERE 
dbid > 0
GROUP BY 
dbid, loginame, hostname, hostprocess

hash[:new_key] = hash.delete :old_key

With fetch, we need to deal with two promises. With axios, we can directly access the JSON result inside the response object data property.

There are several possible answers here. You want to return something that might exist. Here are some options, ranging from my least preferred to most preferred:

• Return by reference, and signal can-not-find by exception.

  Attr& getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return attributes[i];
     //if not found
          throw no_such_attribute_error;
  }

It's likely that not finding attributes is a normal part of execution, and hence not very exceptional. The handling for this would be noisy. A null value cannot be returned because it's undefined behaviour to have null references.

• Return by pointer

  Attr* getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return &attributes[i];
     //if not found
          return nullptr;
  }

It's easy to forget to check whether a result from getAttribute would be a non-NULL pointer, and is an easy source of bugs.

• Use Boost.Optional

  boost::optional<Attr&> getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return attributes[i];
     //if not found
          return boost::optional<Attr&>();
  }

A boost::optional signifies exactly what is going on here, and has easy methods for inspecting whether such an attribute was found.

Side note: std::optional was recently voted into C++17, so this will be a "standard" thing in the near future.

With the following you can insert multiple values and also have default values but you're creating a new dictionary.

d = {**{ key: value }, **default_values}

I've tested it with the most voted answer and on average this is faster as it can be seen in the following example, .

Speed test comparing a for loop based method with a dict comprehension with unpack operator method.

if no copy (d = default_vals.copy()) is made on the first case then the most voted answer would be faster once we reach orders of magnitude of 10**5 and greater. Memory footprint of both methods are the same.

It says right there in the output of git status:

#   (use "git add/rm <file>..." to update what will be committed)

so just do:

git rm <filename>

There's public static class AbstractMap.SimpleEntry<K,V>. Don't let the Abstract part of the name mislead you: it is in fact NOT an abstract class (but its top-level AbstractMap is).

The fact that it's a static nested class means that you DON'T need an enclosing AbstractMap instance to instantiate it, so something like this compiles fine:

Map.Entry<String,Integer> entry =
    new AbstractMap.SimpleEntry<String, Integer>("exmpleString", 42);

As noted in another answer, Guava also has a convenient static factory method Maps.immutableEntry that you can use.

You said:

I can't use Map.Entry itself because apparently it's a read-only object that I can't instantiate new instanceof

That's not entirely accurate. The reason why you can't instantiate it directly (i.e. with new) is because it's an interface Map.Entry.

Caveat and tip

As noted in the documentation, AbstractMap.SimpleEntry is @since 1.6, so if you're stuck to 5.0, then it's not available to you.

To look for another known class that implements Map.Entry, you can in fact go directly to the javadoc. From the Java 6 version

Interface Map.Entry

All Known Implementing Classes:

• AbstractMap.SimpleEntry, AbstractMap.SimpleImmutableEntry

Unfortunately the 1.5 version does not list any known implementing class that you can use, so you may have be stuck with implementing your own.

In my case, this was due to using Integrated Windows Authentication in my data sources while developing reports locally, however once they made it to the report manager, the authentication was broke because the site wasn't properly passing along my credentials.

• The simple fix is to hardcode a username/password into your datasource.
• The harder fix is to properly impersonate/delegate your windows credentials through the report manager, to the underlying datasource.

Try the Remote System Explorer (RSE). It's a set of plug-ins to do exactly what you want.

RSE may already be included in your current Eclipse installation. To check in Eclipse Indigo go to Window > Open Perspective > Other... and choose Remote System Explorer from the Open Perspective dialog to open the RSE perspective.

To create an SSH remote project from the RSE perspective in Eclipse:

1. Define a new connection and choose SSH Only from the Select Remote System Type screen in the New Connection dialog.
2. Enter the connection information then choose Finish.
3. Connect to the new host. (Assumes SSH keys are already setup.)
4. Once connected, drill down into the host's Sftp Files, choose a folder and select Create Remote Project from the item's context menu. (Wait as the remote project is created.)

If done correctly, there should now be a new remote project accessible from the Project Explorer and other perspectives within eclipse. With the SSH connection set-up correctly passwords can be made an optional part of the normal SSH authentication process. A remote project with Eclipse via SSH is now created.

First i tried with this sample code:

$(document).ready(function(){ 
     $('#upload-file').click(); 
});

It didn't work for me. Then after, tried with this

$(document).ready(function(){ 
     $('#upload-file')[0].click(); 
});

No change. At last, tried with this

$(document).ready(function(){ 
     $('#upload-file')[0].click(function(){
     }); 
});

Solved my problem. Helpful for anyone.

As you said the event window.onbeforeunload fires when the users clicks on a link or refreshes the page, so it would not a good even to end a session.

http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx describes all situations where window.onbeforeonload is triggered. (IE)

However, you can place a JavaScript global variable on your pages to identify actions that should not trigger a logoff (by using an AJAX call from onbeforeonload, for example).

The script below relies on JQuery

/*
* autoLogoff.js
*
* Every valid navigation (form submit, click on links) should
* set this variable to true.
*
* If it is left to false the page will try to invalidate the
* session via an AJAX call
*/
var validNavigation = false;

/*
* Invokes the servlet /endSession to invalidate the session.
* No HTML output is returned
*/
function endSession() {
   $.get("<whatever url will end your session>");
}

function wireUpEvents() {

  /*
  * For a list of events that triggers onbeforeunload on IE
  * check http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx
  */
  window.onbeforeunload = function() {
      if (!validNavigation) {
         endSession();
      }
  }

  // Attach the event click for all links in the page
  $("a").bind("click", function() {
     validNavigation = true;
  });

  // Attach the event submit for all forms in the page
  $("form").bind("submit", function() {
     validNavigation = true;
  });

}

// Wire up the events as soon as the DOM tree is ready
$(document).ready(function() {
    wireUpEvents();  
});

This script may be included in all pages

<script type="text/javascript" src="js/autoLogoff.js"></script>

Let's go through this code:

  var validNavigation = false;

  window.onbeforeunload = function() {
      if (!validNavigation) {
         endSession();
      }
  }

  // Attach the event click for all links in the page
  $("a").bind("click", function() {
     validNavigation = true;
  });

  // Attach the event submit for all forms in the page
  $("form").bind("submit", function() {
     validNavigation = true;
  });

A global variable is defined at page level. If this variable is not set to true then the event windows.onbeforeonload will terminate the session.

An event handler is attached to every link and form in the page to set this variable to true, thus preventing the session from being terminated if the user is just submitting a form or clicking on a link.

function endSession() {
   $.get("<whatever url will end your session>");
}

The session is terminated if the user closed the browser/tab or navigated away. In this case the global variable was not set to true and the script will do an AJAX call to whichever URL you want to end the session

This solution is server-side technology agnostic. It was not exaustively tested but it seems to work fine in my tests

Is JSTL's join(), what you searched for?

<c:set var="myVar" value="${fn:join(myParams.items, ' ')}" />

The story of %2F vs / was that, according to the initial W3C recommendations, slashes «must imply a hierarchical structure»:

The slash ("/", ASCII 2F hex) character is reserved for the delimiting of substrings whose relationship is hierarchical. This enables partial forms of the URI.

Example 2

The URIs

http://www.w3.org/albert/bertram/marie-claude

and

http://www.w3.org/albert/bertram%2Fmarie-claude

are NOT identical, as in the second case the encoded slash does not have hierarchical significance.

If you are testing for file existence you want -e not -L. -L tests for a symlink.

This can be done using REGEXP_SUBSTR easily.

Please use

REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 

where STRING_EXAMPLE is your string.

Try:

SELECT 
REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 
from dual

It will solve your problem.

If you are using linux system then you need to add

using namespace std;

Below headers

If windows then make sure you put headers correctly #include<iostream.h>

#include<string.h>

Refer this it work perfectly.

#include <iostream>
#include <string>

int main ()
{
std::string str="We think in generalities, but we live in details.";
                                       // (quoting Alfred N. Whitehead)

  std::string str2 = str.substr (3,5);     // "think"

   std::size_t pos = str.find("live");      // position of "live" in str

  std::string str3 = str.substr (pos);     
// get from "live" to the end

  std::cout << str2 << ' ' << str3 << '\n';

  return 0;
}

1. delimiter ;;
2. CREATE PROCEDURE sp_number_example_records()
3. BEGIN
   SELECT count(id) from customer; END
4. ;;

if you want generate a random float with N digits to the right of point, you can make this :

round(random.uniform(1,2), N)

the second argument is the number of decimals.

You can use the Free version of HTTP Debugger.

It is not a proxy and you needn't make any changes in web.config.

Also, it can show both; incoming and outgoing HTTP requests. HTTP Debugger Free

public class AssemblyLoader<T>  where T:class
{
    public void(){
        var res = Load(@"C:\test\paquete.uno.dos.test.dll", "paquete.uno.dos.clasetest.dll") 
    }

    public T Load(string assemblyFile, string objectToInstantiate) 
    {
        var loaded = Activator.CreateInstanceFrom(assemblyFile, objectToInstantiate).Unwrap();

        return loaded as T;
    }
}

Below worked for me.

Height & width are taken to show that, if you 2 such children, it will scroll horizontally, since height of child is greater than height of parent scroll vertically.

Parent CSS:

.divParentClass {
    width: 200px;
    height: 100px;
    overflow: scroll;
    white-space: nowrap;
}

Children CSS:

.divChildClass {
    width: 110px;
    height: 200px;
    display: inline-block;
}

To scroll horizontally only:

overflow-x: scroll;
overflow-y: hidden;

To scroll vertically only:

overflow-x: hidden;
overflow-y: scroll;

Here are the complete list of scripts required to get rid of this problem. (Make sure the file exists at the given file path)

   <script src="@Url.Content("~/Scripts/jquery-1.8.2.js")" type="text/javascript">

    </script>
    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript">
    </script>

and also include the below css link in _Layout.cshtml for a stylish popup.

<link rel="stylesheet" type="text/css" href="../../Content/themes/base/jquery-ui.css" />

The error Event the onerror handler receives is a simple event not containing such information:

If the user agent was required to fail the WebSocket connection or the WebSocket connection is closed with prejudice, fire a simple event named error at the WebSocket object.

You may have better luck listening for the close event, which is a CloseEvent and indeed has a CloseEvent.code property containing a numerical code according to RFC 6455 11.7 and a CloseEvent.reason string property.

Please note however, that CloseEvent.code (and CloseEvent.reason) are limited in such a way that network probing and other security issues are avoided.

If you need to run a shell command on multiple files, this did the trick for me.

import os
import subprocess

# Define a function for running commands and capturing stdout line by line
# (Modified from Vartec's solution because it wasn't printing all lines)
def runProcess(exe):    
    p = subprocess.Popen(exe, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    return iter(p.stdout.readline, b'')

# Get all filenames in working directory
for filename in os.listdir('./'):
    # This command will be run on each file
    cmd = 'nm ' + filename

    # Run the command and capture the output line by line.
    for line in runProcess(cmd.split()):
        # Eliminate leading and trailing whitespace
        line.strip()
        # Split the output 
        output = line.split()

        # Filter the output and print relevant lines
        if len(output) > 2:
            if ((output[2] == 'set_program_name')):
                print filename
                print line

Edit: Just saw Max Persson's solution with J.F. Sebastian's suggestion. Went ahead and incorporated that.

You are importing from package "sub". start.py is not itself in a package even if there is a __init__.py present.

You would need to start your program from one directory over parent.py:

./start.py

./pkg/__init__.py
./pkg/parent.py
./pkg/sub/__init__.py
./pkg/sub/relative.py

With start.py:

import pkg.sub.relative

Now pkg is the top level package and your relative import should work.

If you want to stick with your current layout you can just use import parent. Because you use start.py to launch your interpreter, the directory where start.py is located is in your python path. parent.py lives there as a separate module.

You can also safely delete the top level __init__.py, if you don't import anything into a script further up the directory tree.

I have not used Bootstrap but I worked on Zurb Foundation. On that I used to add space like this.

<div id="main" class="container" role="main">
    <div class="row">

        <div class="span5 offset1">
            <h2>Welcome</h2>
            <p>Hello and welcome to my website.</p>
        </div>
        <div class="span6">
            Image Here (TODO)
        </div>
    </div>

Visit this link: http://getbootstrap.com/2.3.2/scaffolding.html and read the section: Offsetting columns.

I think I know what you are doing wrong. If you are applying padding to the span6 like this:

<div class="span6" style="padding-left:5px;">
    <h2>Welcome</h2>
    <p>Hello and welcome to my website.</p>
</div>

It is wrong. What you have to do is add padding to the elements inside:

<div class="span6">
    <h2 style="padding-left:5px;">Welcome</h2>
    <p  style="padding-left:5px;">Hello and welcome to my website.</p>
</div>

Initially I tried the Fusion log viewer, but that didn't help so I ended up using WinDbg with the SOS extension.

!dumpheap -stat -type Exception /D

Then I examined the FileNotFoundExceptions. The message in the exception contained the name of the DLL that wasn't loading.

N.B., the /D give you hyperlinked results, so click on the link in the summary for FileNotFoundException. That will bring up a list of the exceptions. Then click on the link for one of the exceptions. That will !dumpobject that exceptions. Then you should just be able to click on the link for Message in the exception object, and you'll see the text.

I also meet this problem, and I found the solution as 2 step below: 1. In sites-enabled folder of apache2, you edit in Directory element by set "AllowOverride all" (should be "all" not "none") 2. In kohana project in www folder, rename "example.htaccess" to ".htaccess"

I did it on ubuntu. Hope that it will help you.

Have you tried loading the socket.io script not from a relative URL?

You're using:

<script src="socket.io/socket.io.js"></script>

And:

socket.connect('http://127.0.0.1:8080');

You should try:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

And:

socket.connect('http://localhost:8080');

Switch localhost:8080 with whatever fits your current setup.

Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).

You are using Python 2 for which the input() function tries to evaluate the expression entered. Because you enter a string, Python treats it as a name and tries to evaluate it. If there is no variable defined with that name you will get a NameError exception.

To fix the problem, in Python 2, you can use raw_input(). This returns the string entered by the user and does not attempt to evaluate it.

Note that if you were using Python 3, input() behaves the same as raw_input() does in Python 2.

EUROPE:

declare @d datetime;
set @d=getdate();
set @dow=((datepart(dw,@d) + @@DATEFIRST-2) % 7+1);

If I'm not wrong, what you're trying to achieve is called Sticky navbar.

With a few lines of jQuery and the scroll event is pretty easy to achieve:

$(document).ready(function() {

    var menu = $('.menu');
    var content = $('.content');
    var origOffsetY = menu.offset().top;

    function scroll() {
        if ($(window).scrollTop() >= origOffsetY) {
            menu.addClass('sticky');
            content.addClass('menu-padding');
        } else {
            menu.removeClass('sticky');
            content.removeClass('menu-padding');
        }
    }

    $(document).scroll();

});

I've done a quick working sample for you, hope it helps: http://jsfiddle.net/yeco/4EcFf/

To make it work with Bootstrap you only need to add or remove "navbar-fixed-top" instead of the "sticky" class in the jsfiddle .

The using syntax has an advantage when used within templates. If you need the type abstraction, but also need to keep template parameter to be possible to be specified in future. You should write something like this.

template <typename T> struct whatever {};

template <typename T> struct rebind
{
  typedef whatever<T> type; // to make it possible to substitue the whatever in future.
};

rebind<int>::type variable;

template <typename U> struct bar { typename rebind<U>::type _var_member; }

But using syntax simplifies this use case.

template <typename T> using my_type = whatever<T>;

my_type<int> variable;
template <typename U> struct baz { my_type<U> _var_member; }

Assuming your categories are in cells A1:A6 and the corresponding values are in B1:B6, you might try typing the formula =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) in another cell and then pressing CTRL+SHIFT+ENTER.

Using CTRL+SHIFT+ENTER tells Excel to treat the formula as an "array formula". In this example, that means that the IF statement returns an array of 6 values (one of each of the cells in the range $A$1:$A$6) instead of a single value. The MEDIAN function then returns the median of these values. See http://www.cpearson.com/excel/arrayformulas.aspx for a similar example using AVERAGE instead of MEDIAN.

SQL Server Express editions are limited in some ways - one way is that they don't have the SQL Agent that allows you to schedule jobs.

There are a few third-party extensions that provide that capability - check out e.g.:

• Express Agent for SQL Server Express: Jobs, Jobs, Jobs and Mail (latest update is from 2005, it isn't maintained anymore).
• SQL Scheduler

import pygame, sys
from pygame.locals import *

def main():
    pygame.init()

    DISPLAY=pygame.display.set_mode((500,400),0,32)

    WHITE=(255,255,255)
    BLUE=(0,0,255)

    DISPLAY.fill(WHITE)

    pygame.draw.rect(DISPLAY,BLUE,(200,150,100,50))

    while True:
        for event in pygame.event.get():
            if event.type==QUIT:
                pygame.quit()
                sys.exit()
        pygame.display.update()

main()

This creates a simple window 500 pixels by 400 pixels that is white. Within the window will be a blue rectangle. You need to use the pygame.draw.rect to go about this, and you add the DISPLAY constant to add it to the screen, the variable blue to make it blue (blue is a tuple that values which equate to blue in the RGB values and it's coordinates.

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

The problem is that your ui property uses a forward declaration of class Ui::MainWindowClass, hence the "incomplete type" error.

Including the header file in which this class is declared will fix the problem.

EDIT

Based on your comment, the following code:

namespace Ui
{
    class MainWindowClass;
}

does NOT declare a class. It's a forward declaration, meaning that the class will exist at some point, at link time.
Basically, it just tells the compiler that the type will exist, and that it shouldn't warn about it.

But the class has to be defined somewhere.

Note this can only work if you have a pointer to such a type.
You can't have a statically allocated instance of an incomplete type.

So either you actually want an incomplete type, and then you should declare your ui member as a pointer:

namespace Ui
{
    // Forward declaration - Class will have to exist at link time
    class MainWindowClass;
}

class MainWindow : public QMainWindow
{
    private:

        // Member needs to be a pointer, as it's an incomplete type
        Ui::MainWindowClass * ui;
};

Or you want a statically allocated instance of Ui::MainWindowClass, and then it needs to be declared. You can do it in another header file (usually, there's one header file per class).
But simply changing the code to:

namespace Ui
{
    // Real class declaration - May/Should be in a specific header file
    class MainWindowClass
    {};
}


class MainWindow : public QMainWindow
{
    private:

        // Member can be statically allocated, as the type is complete
        Ui::MainWindowClass ui;
};

will also work.

Note the difference between the two declarations. First uses a forward declaration, while the second one actually declares the class (here with no properties nor methods).

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

        String number;

        while(true){

            try{
                number = JOptionPane.showInputDialog(null);

                if( Main.isNumber(number) )
                    break;

            }catch(NumberFormatException e){
                System.out.println(e.getMessage());
            }

        }

        System.out.println("Your number is " + number);

    }

    public static boolean isNumber(Object o){
        boolean isNumber = true;

        for( byte b : o.toString().getBytes() ){
            char c = (char)b;
            if(!Character.isDigit(c))
                isNumber = false;
        }

        return isNumber;
    }

}

This function returns a array of int in the string form like "6097321041141011026"

private String IntArrayToString(byte[] array) {
        String strRet="";
        for(int i : array) {
            strRet+=Integer.toString(i);
        }
        return strRet;
    }

SELECT NVL(SomeNullableField, 'If null, this value') FROM SomeTable

To get left and right tabs (now also with sideways) support for Bootstrap 3, bootstrap-vertical-tabs component can be used.

https://github.com/dbtek/bootstrap-vertical-tabs

For C++:

In case of using keyboard characters/numbers, an easier solution would be:

int key = cvWaitKey();

switch(key)
{
   case ((int)('a')):
   // do something if button 'a' is pressed
   break;
   case ((int)('h')):
   // do something if button 'h' is pressed
   break;
}

Just to let you know:

When you write list1 + list2, you are calling the __add__ method of list1, which returns a new list. in this way you can also deal with myobject + list1 by adding the __add__ method to your personal class.

send an output parameter like

@newId int output

at the end use

    select @newId = Scope_Identity() 

     return @newId 

Facing similar concern, I found the following tool with a trivial Google search :

JPSoft's "Take Command" includes a batch file IDE/debugger. Their short presentation video demonstrates it nicely.

I'm using the trial version since a few hours. Here is my first humble opinion:

• On one side, it indeed allows debugging .bat and .cmd scripts and I'm now convinced it can help in quite some cases
• On the other hand, it sometimes blocks and I had to kill it... specially when debugging subscripts (not always systematically).. it doesn't show a "call stack" nor a "step out" button.

It deverves a try.

You forgot to add the width of the two divs.

.header {
    position: fixed;
    top:0;
    background-color: #f00;
    height: 100px; width: 100%;
}
.footer {
    position: fixed;
    bottom: 0;
    background-color: #f0f;
    height: 120px; width:100%;
}

demo

You can use \ to indicate that any line of Ruby continues on the next line. This works with strings too:

string = "this is a \
string that spans lines"

puts string.inspect

will output "this is a string that spans lines"

The hint is, the output file is created even if you get this error. The automatic deconstruction of vector starts after your code executed. Elements in the vector are deconstructed as well. This is most probably where the error occurs. The way you access the vector is through vector::operator[] with an index read from stream. Try vector::at() instead of vector::operator[]. This won't solve your problem, but will show which assignment to the vector causes error.

Use crosstab() from the tablefunc module.

SELECT * FROM crosstab(
   $$SELECT user_id, user_name, rn, email_address
     FROM  (
        SELECT u.user_id, u.user_name, e.email_address
             , row_number() OVER (PARTITION BY u.user_id
                            ORDER BY e.creation_date DESC NULLS LAST) AS rn
        FROM   usr u
        LEFT   JOIN email_tbl e USING (user_id)
        ) sub
     WHERE  rn < 4
     ORDER  BY user_id
   $$
  , 'VALUES (1),(2),(3)'
   ) AS t (user_id int, user_name text, email1 text, email2 text, email3 text);

I used dollar-quoting for the first parameter, which has no special meaning. It's just convenient if you have to escape single quotes in the query string which is a common case:

• Insert text with single quotes in PostgreSQL

Detailed explanation and instructions here:

• PostgreSQL Crosstab Query

And in particular, for "extra columns":

• Pivot on Multiple Columns using Tablefunc

The special difficulties here are:

• The lack of key names.
  -> We substitute with row_number() in a subquery.

• The varying number of emails.
  -> We limit to a max. of three in the outer SELECT
  and use crosstab() with two parameters, providing a list of possible keys.

Pay attention to NULLS LAST in the ORDER BY.

Steps:

1. Create a dataframe
2. Create a function
3. Use the named arguments of the function in the apply statement.

Example

x=pd.DataFrame([1,2,3,4])  

def add(i1, i2):  
    return i1+i2

x.apply(add,i2=9)

The outcome of this example is that each number in the dataframe will be added to the number 9.

    0
0  10
1  11
2  12
3  13

Explanation:

The "add" function has two parameters: i1, i2. The first parameter is going to be the value in data frame and the second is whatever we pass to the "apply" function. In this case, we are passing "9" to the apply function using the keyword argument "i2".

I would try any(byte[].class)

select * from sqlite_master where type = 'table' and tbl_name = 'TableName' and sql like '%ColumnName%'

Logic: sql column in sqlite_master contains table definition, so it certainly contains string with column name.

As you are searching for a sub-string, it has its obvious limitations. So I would suggest to use even more restrictive sub-string in ColumnName, for example something like this (subject to testing as '`' character is not always there):

select * from sqlite_master where type = 'table' and tbl_name = 'MyTable' and sql like '%`MyColumn` TEXT%'

Changing text color of button

Because this method is now deprecated

button.setTextColor(getResources().getColor(R.color.your_color));

I use the following:

button.setTextColor(ContextCompat.getColor(mContext, R.color.your_color));

1. Download from http://www.mongodb.org/downloads
2. Install .msi file in folder C:\mongodb
3. Create data, data\db, log directories and mongo.config file under C:\mongodb.

4. Add the following lines in "mongo.config" file

   port=27017
   dbpath=C:\mongodb\data\db\
   logpath=C:\mongodb\log\mongo.log
   

5. Start server :

   mongod.exe --config="C:\mongodb\mongo.config"
   

6. Connect to localhost MongoDB server via command line

   mongo --port 27017
   

7. Connect to remote MongoDB server via command line with authentication.

   mongo --username abcd --password abc123 --host server_ip_or_dns --port 27017
   

That's it !!!

I found a way that seems to work better for me:

ssh-keygen -y -f <private key file>

That command will output the public key for the given private key, so then just compare the output to each *.pub file.

Convert JavaScript object to json data

$("form").submit(function(event){
  event.preventDefault();
  var formData = $("form").serializeArray(); // Create array of object
  var jsonConvertedData = JSON.stringify(formData);  // Convert to json
  consol.log(jsonConvertedData);
});

You can validate json data using http://jsonlint.com

(A || B) && !(A && B)

The first part is A OR B, which is the Inclusive OR; the second part is, NOT A AND B. Together you get A or B, but not both A and B.

This will provide the XOR proved in the truth table below.

|-----|-----|-----------|
|  A  |  B  |  A XOR B  |
|-----|-----|-----------|
|  T  |  T  |   False   |
|-----|-----|-----------|
|  T  |  F  |   True    |
|-----|-----|-----------|
|  F  |  T  |   True    |
|-----|-----|-----------|
|  F  |  F  |   False   |
|-----|-----|-----------|

Alternatively, if you want to get the IP address of whichever interface is used to connect to the network without having to know its name, you can use this:

import socket
def get_ip_address():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.connect(("8.8.8.8", 80))
    return s.getsockname()[0]

I know it's a little different than your question, but others may arrive here and find this one more useful. You do not have to have a route to 8.8.8.8 to use this. All it is doing is opening a socket, but not sending any data.

I had the same issue recently on my test server. After searching for reasons this might be happening and testing the solutions I found here, I recalled that I had clicked the "Stop this page from creating pop-ups" option a few hours before when the script I was working on was wildly popping up alerts.

The solution was as simple as closing the tab and opening a fresh one!

Programmatic formatting solution:

The JSON.stringify method supported by many modern browsers (including IE8) can output a beautified JSON string:

JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4);    // stringify with 4 spaces at each level

Demo: http://jsfiddle.net/AndyE/HZPVL/

This method is also included with json2.js, for supporting older browsers.

Manual formatting solution

If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.

Smoothly scroll to the proper position (2019)

Get correct y coordinate and use window.scrollTo({top: y, behavior: 'smooth'})

const id = 'anchorName2';
const yourElement = document.getElementById(id);
const y = yourElement.getBoundingClientRect().top + window.pageYOffset;

window.scrollTo({top: y, behavior: 'smooth'});

With offset

scrollIntoView is a good option too but it may not works perfectly in some cases. For example when you need additional offset. With scrollTo you just need to add that offset like this:

const yOffset = -10; 

window.scrollTo({top: y + yOffset, behavior: 'smooth'});

This example shows how to publish log files in JBoss through a rest resource. Note the get method uses the StreamingOutput interface to stream the content of the log file.

Please refer below TSQL. STRING_SPLIT function is available only under compatibility level 130 and above.

TSQL:

DECLARE @stringValue NVARCHAR(400) = 'red,blue,green,yellow,black'  
DECLARE @separator CHAR = ','

SELECT [value]  As Colour
FROM STRING_SPLIT(@stringValue, @separator); 

RESULT:

Colour

red blue green yellow black

These are literals and are described in section 3.10 of the Java language spec.

You either want to select an anonymous type:

var dataset2 = from recordset 
               in entities.processlists 
               where recordset.ProcessName == processname 
               select new 
               {
                recordset.ServerName, 
                recordset.ProcessID, 
                recordset.Username
               };

But you cannot cast that to another type, so I guess you want something like this:

var dataset2 = from recordset 
               in entities.processlists 
               where recordset.ProcessName == processname 

               // Select new concrete type
               select new PInfo
               {
                ServerName = recordset.ServerName, 
                ProcessID = recordset.ProcessID, 
                Username = recordset.Username
               };

You're probably trying to to update the same row of the target table multiple times. I just encountered the very same problem in a merge statement I developed. Make sure your update does not touch the same record more than once in the execution of the merge.

Adding to the other answers, in Node.js it is possible to use require to read JSON files even inside ES modules. I found this to be especially useful when reading files inside other packages, because it takes advantage of Node's own module resolution strategy to locate the file.

require in an ES module must be first created with createRequire.

Here is a complete example:

import { createRequire } from 'module';

const require = createRequire(import.meta.url);
const packageJson = require('typescript/package.json');
console.log(`You have TypeScript version ${packageJson.version} installed.`);

In a project with TypeScript installed, the code above will read and print the TypeScript version number from package.json.

public boolean deleteSms(String smsId) {
    boolean isSmsDeleted = false;
    try {
        mActivity.getContentResolver().delete(Uri.parse("content://sms/" + smsId), null, null);
        isSmsDeleted = true;

    } catch (Exception ex) {
        isSmsDeleted = false;
    }
    return isSmsDeleted;
}

Yes but ....

Ruby passes a reference to an object and since everything in ruby is an object, then you could say it's pass by reference.

I don't agree with the postings here claiming it's pass by value, that seems like pedantic, symantic games to me.

However, in effect it "hides" the behaviour because most of the operations ruby provides "out of the box" - for example string operations, produce a copy of the object:

> astringobject = "lowercase"

> bstringobject = astringobject.upcase
> # bstringobject is a new object created by String.upcase

> puts astringobject
lowercase

> puts bstringobject
LOWERCASE

This means that much of the time, the original object is left unchanged giving the appearance that ruby is "pass by value".

Of course when designing your own classes, an understanding of the details of this behaviour is important for both functional behaviour, memory efficiency and performance.

Just set your java_home property with java home (eg:C:\Program Files\Java\jdk1.7.0_25) directory. Close command prompt and reopen it. Then error relating to tools.jar will be solved. For the second one("build.xml not found ") you should have to ensure your command line also at the directory where your build.xml file resides.

This will NOT work as an apache module, you need to be using CGI.

If you see your error message it says

Building in workspace /var/lib/jenkins/workspace/AutoScript

and as per your comments you have put urltest.sh in

/var/lib/jenkins

Hence Jenkins is not able to find the file. In your build step do this thing, it will work

cd             # which will point to /var/lib/jenkins
./urltest.sh   # it will run your script

If it still fails try to chown the file as jenkin user may not have file permission, but I think if you do above step you will be able to run.

There's no such thing as the "first" key in a hash (Javascript calls them objects). They are fundamentally unordered. Do you mean just choose any single key:

for (var k in ahash) {
    break
}

// k is a key in ahash.

You might not be able to change npm registry using .bat file as Gntem pointed out. But I understand that you need the ability to automate changing registries. You can do so by having your .npmrc configs in separate files (say npmrc_jfrog & npmrc_default) and have your .bat files do the copying task.

For example (in Windows): Your default_registry.bat will have

xcopy /y npmrc_default .npmrc

and your jfrog_registry.bat will have

xcopy /y npmrc_jfrog .npmrc

Note: /y suppresses prompting to confirm that you want to overwrite an existing destination file.

This will make sure that all the config properties (registry, proxy, apiKeys, etc.) get copied over to .npmrc.

You can read more about xcopy here.

byte * matToBytes(Mat image)
{
   int size = image.total() * image.elemSize();
   byte * bytes = new byte[size];  //delete[] later
   std::memcpy(bytes,image.data,size * sizeof(byte));
}

I am agree with raukodraug therefor using in a swithview you must request/clear focus like this :

    final ViewSwitcher viewSwitcher = (ViewSwitcher) findViewById(R.id.viewSwitcher);
    final View btn = viewSwitcher.findViewById(R.id.address_btn);
    final View title = viewSwitcher.findViewById(R.id.address_value);

    title.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            viewSwitcher.showPrevious();
            btn.requestFocus();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(btn, InputMethodManager.SHOW_IMPLICIT);
        }
    });

    // EditText affiche le titre evenement click
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            btn.clearFocus();
            viewSwitcher.showNext();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(btn.getWindowToken(), 0);
            // Enregistre l'adresse.
            addAddress(view);
        }
    });

It works with C#.

Dashes don't need to be removed from HTTP request as you can see in URL of this thread. But if you want to prepare well-formed URL without dependency on data you should use URLEncoder.encode( String data, String encoding ) instead of changing standard form of you data. For UUID string representation dashes is normal.

I know this post has been (very well) answered by Aquarelle but just in case somebody is having this issue with other tag forms with no text such as inputs i'll leave this here:

If you have an input in your form and placeholder is not showing because a white space at the beginning, this may be caused for you "value" attribute. In case you are using variables to fill the value of an input check that there are no white spaces between the commas and the variables.

example using twig for php framework symfony :

<input type="text" name="subject" value="{{ subject }}" placeholder="hello" />       <-- this is ok
<input type="text" name="subject" value" {{ subject }} " placeholder="hello" />      <-- this will not show placeholder 

In this case the tag between {{ }} is the variable, just make sure you are not leaving spaces between the commas because white space is also a valid character.

Use the -C switch of tar:

tar -czvf my_directory.tar.gz -C my_directory .

The -C my_directory tells tar to change the current directory to my_directory, and then . means "add the entire current directory" (including hidden files and sub-directories).

Make sure you do -C my_directory before you do . or else you'll get the files in the current directory.

you have a few options here:

1. Using the UsedRange property
2. find the last row and column used
3. use a mimic of shift down and shift right

I personally use the Used Range and find last row and column method most of the time.

Here's how you would do it using the UsedRange property:

Sheets("Sheet_Name").UsedRange.Select

This statement will select all used ranges in the worksheet, note that sometimes this doesn't work very well when you delete columns and rows.

The alternative is to find the very last cell used in the worksheet

Dim rngTemp As Range
Set rngTemp = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
If Not rngTemp Is Nothing Then
    Range(Cells(1, 1), rngTemp).Select
End If

What this code is doing:

1. Find the last cell containing any value
2. select cell(1,1) all the way to the last cell

As other people have commented, because the return type of your method is String Spring won't feel need to do anything with the result.

If you change your signature so that the return type is something that needs marshalling, that should help:

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")
@ResponseBody
public Map<String, Object> bar() {
    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put("test", "jsonRestExample");
    return map;
}

Most modern browser support console.dir(obj), which will return all the properties of an object that it inherited through its constructor. See Mozilla's documentation for more info and current browser support.

console.dir(Math)
=> MathConstructor
E: 2.718281828459045
LN2: 0.6931471805599453
...
tan: function tan() { [native code] }
__proto__: Object

Make sure you specify pass header=None and add usecols=[3,6] for the 4th and 7th columns.

You don't need a function for it - simply use the bracket notation:

var side = columns['right'];

This is equal to dot notation, var side = columns.right;, except the fact that right could also come from a variable, function return value, etc., when using bracket notation.

If you NEED a function for it, here it is:

function read_prop(obj, prop) {
    return obj[prop];
}

To answer some of the comments below that aren't directly related to the original question, nested objects can be referenced through multiple brackets. If you have a nested object like so:

var foo = { a: 1, b: 2, c: {x: 999, y:998, z: 997}};

you can access property x of c as follows:

var cx = foo['c']['x']

If a property is undefined, an attempt to reference it will return undefined (not null or false):

foo['c']['q'] === null
// returns false

foo['c']['q'] === false
// returns false

foo['c']['q'] === undefined
// returns true

Image.paste does not work as expected when the background image also contains transparency. You need to use real Alpha Compositing.

Pillow 2.0 contains an alpha_composite function that does this.

background = Image.open("test1.png")
foreground = Image.open("test2.png")

Image.alpha_composite(background, foreground).save("test3.png")

EDIT: Both images need to be of the type RGBA. So you need to call convert('RGBA') if they are paletted, etc.. If the background does not have an alpha channel, then you can use the regular paste method (which should be faster).

Based on the other answers above and some subtle issues, here is my attempt.

1. Only create the fs.createWriteStream if you get a 200 OK status code. This reduces the amount of fs.unlink commands required to tidy up temporary file handles.
2. Even on a 200 OK we can still possibly reject due to an EEXIST file already exists.
3. Recursively call download if you get a 301 Moved Permanently or 302 Found (Moved Temporarily) redirect following the link location provided in the header.
4. The issue with some of the other answers recursively calling download was that they called resolve(download) instead of download(...).then(() => resolve()) so the Promise would return before the download actually finished. This way the nested chain of promises resolve in the correct order.
5. It might seem cool to clean up the temp file asynchronously, but I chose to reject only after that completed too so I know that everything start to finish is done when this promise resolves or rejects.

const https = require('https');
const fs = require('fs');

/**
 * Download a resource from `url` to `dest`.
 * @param {string} url - Valid URL to attempt download of resource
 * @param {string} dest - Valid path to save the file.
 * @returns {Promise<void>} - Returns asynchronously when successfully completed download
 */
function download(url, dest) {
  return new Promise((resolve, reject) => {
    const request = https.get(url, response => {
      if (response.statusCode === 200) {
 
        const file = fs.createWriteStream(dest, { flags: 'wx' });
        file.on('finish', () => resolve());
        file.on('error', err => {
          file.close();
          if (err.code === 'EEXIST') reject('File already exists');
          else fs.unlink(dest, () => reject(err.message)); // Delete temp file
        });
        response.pipe(file);
      } else if (response.statusCode === 302 || response.statusCode === 301) {
        //Recursively follow redirects, only a 200 will resolve.
        download(response.headers.location, dest).then(() => resolve());
      } else {
        reject(`Server responded with ${response.statusCode}: ${response.statusMessage}`);
      }
    });

    request.on('error', err => {
      reject(err.message);
    });
  });
}

Simple method worked:

setSingleLine();
setIncludeFontPadding(false);

If it not worked, then try to add this above that code:

setLineSpacing(0f,0f);
// and set padding and margin to 0

If you need multi line, maybe you'll need to calculate exactly the height of padding top and bottom via temp single line TextView (before and after remove padding) , then apply decrease height result with negative padding or some Ghost Layout with translate Y. Lol

Your problem is on the call for the dialog

If you dont initialize the dialog, you don't have to pass "open" for it to show:

$("#dialog").dialog();

Also, this code needs to be on a $(document).ready(); function or be below the elements for it to work.

Why not try to use the Babylonian method for finding a square root.

Here is my code for it:

double sqrt(double number)
{
    double error = 0.00001; //define the precision of your result
    double s = number;

    while ((s - number / s) > error) //loop until precision satisfied 
    {
        s = (s + number / s) / 2;
    }
    return s;
}

Good luck!

I sometimes have this same problem. VSCode will just suddenly lose it's mind and completely ignore any indentation setting I tell it, even though it's been indenting the same file just fine all day.

I have editor.tabSize set to 2 (as well as editor.formatOnSave set to true). When VSCode messes up a file, I use the options at the bottom of the editor to change indentation type and size, hoping something will work, but VSCode insists on actually using an indent size of 4.

The fix? Restart VSCode. It should come back with the indent status showing something wrong (in my case, 4). For me, I had to change the setting and then save for it to actually make the change, but that's probably because of my editor.formatOnSave setting.

I haven't figured out why it happens, but for me it's usually when I'm editing a nested object in a JS file. It will suddenly do very strange indentation within the object, even though I've been working in that file for a while and it's been indenting just fine.

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

ObjectOutputStream.writeObject(clubs)
ObjectInputStream.readObject();

Also, you 'add' logic is logically equivalent to using a Set instead of a List. Lists can have duplicates and Sets cannot. You should consider using a set. After all, can you really have 2 chess clubs in the same school?

I think, if You need normalized data tables - You need to try some other database solutions.

But I've foun that sollution for MOngo on Git By the way, in inserts code - it has movie's name, but noi movie's ID.

Problem

You have a collection of Actors with an array of the Movies they've done.

You want to generate a collection of Movies with an array of Actors in each.

Some sample data

 db.actors.insert( { actor: "Richard Gere", movies: ['Pretty Woman', 'Runaway Bride', 'Chicago'] });
 db.actors.insert( { actor: "Julia Roberts", movies: ['Pretty Woman', 'Runaway Bride', 'Erin Brockovich'] });

Solution

We need to loop through each movie in the Actor document and emit each Movie individually.

The catch here is in the reduce phase. We cannot emit an array from the reduce phase, so we must build an Actors array inside of the "value" document that is returned.

map = function() {
  for(var i in this.movies){
    key = { movie: this.movies[i] };
    value = { actors: [ this.actor ] };
    emit(key, value);
  }
}

reduce = function(key, values) {
  actor_list = { actors: [] };
  for(var i in values) {
    actor_list.actors = values[i].actors.concat(actor_list.actors);
  }
  return actor_list;
}

Notice how actor_list is actually a javascript object that contains an array. Also notice that map emits the same structure.

Run the following to execute the map / reduce, output it to the "pivot" collection and print the result:

printjson(db.actors.mapReduce(map, reduce, "pivot")); db.pivot.find().forEach(printjson);

Here is the sample output, note that "Pretty Woman" and "Runaway Bride" have both "Richard Gere" and "Julia Roberts".

{ "_id" : { "movie" : "Chicago" }, "value" : { "actors" : [ "Richard Gere" ] } }
{ "_id" : { "movie" : "Erin Brockovich" }, "value" : { "actors" : [ "Julia Roberts" ] } }
{ "_id" : { "movie" : "Pretty Woman" }, "value" : { "actors" : [ "Richard Gere", "Julia Roberts" ] } }
{ "_id" : { "movie" : "Runaway Bride" }, "value" : { "actors" : [ "Richard Gere", "Julia Roberts" ] } }

When I'm not worried about performance, I'll often use this:

if my_string.to_s == ''
  # It's nil or empty
end

There are various variations, of course...

if my_string.to_s.strip.length == 0
  # It's nil, empty, or just whitespace
end

GPS will be used if the user has allowed it to be used in its settings.

You can't explicitly switch this on anymore, but you don't have to - it's a privacy setting really, so you don't want to tweak it. If the user is OK with apps getting precise co-ordinates it'll be on. Then the location manager API will use GPS if it can.

If your app really isn't useful without GPS, and it's off, you can open the settings app at the right screen using an intent so the user can enable it.

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

This works for me:

$('#element').click(function (e) {
        if (e.offsetX > e.target.offsetLeft) {
            // click on element
        }
         else{
           // click on ::before element
       }
});

You've missed the id out before the NOT; it needs to be specified.

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

To add to this - it seems important to define the width & height of the drawable as per this post:

• Drawable shape not showing when used in combination with android:drawableBottom attribute.

(his code works)

You can create a base class in your application that inherits from System.Web.UI.Page. Let all your pages inherit from the newly created base class. Add a property or a variable to your base class with propected access modifier, so that it will be accessed from all your pages in the application.

I also upvote Neil answer : curl -I http://websitename.com

I made a small change to Softlion answer, so all my modals won't refresh on hide. The modals with data-refresh='true' attribute are only refreshed, others work as usual. Here is the modified version.

$(document).on('hidden.bs.modal', function (e) {
    if ($(e.target).attr('data-refresh') == 'true') {
        // Remove modal data
        $(e.target).removeData('bs.modal');
        // Empty the HTML of modal
        $(e.target).html('');
    }
});

Now use the attribute as shown below,

<div class="modal fade" data-refresh="true" id="#modal" tabindex="-1" role="dialog" aria-labelledby="#modal-label" aria-hidden="true"></div>

This will make sure only the modals with data-refresh='true' are refreshed. And i'm also resetting the modal html because the old values are shown until new ones get loaded, making html empty fixes that one.

Although accepted answer is right, but IMHO is just a workaround.

To be clear: it's a perfectly normal situation that a persistent connection may become stale. But unfortunately it's very bad when the HTTP client library cannot handle it properly.

Since this faulty behavior in Apache HttpClient was not fixed for many years, I definitely would prefer to switch to a library that can easily recover from a stale connection problem, e.g. OkHttp.

Why?

1. OkHttp pools http connections by default.
2. It gracefully recovers from situations when http connection becomes stale and request cannot be retried due to being not idempotent (e.g. POST). I cannot say it about Apache HttpClient (mentioned NoHttpResponseException).
3. Supports HTTP/2.0 from early drafts and beta versions.

When I switched to OkHttp, my problems with NoHttpResponseException disappeared forever.

In a Windows Application you could do someting like this:

public partial class App : Application  
{  
     public App()  
     {             
     }  
 
     protected override void OnStartup(StartupEventArgs e)  
     {  
         Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("de-DE"); ;  
         Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("de-DE"); ;  
 
          FrameworkElement.LanguageProperty.OverrideMetadata(  
              typeof(FrameworkElement),  
              new FrameworkPropertyMetadata(  
                  XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));  
          base.OnStartup(e);  
    }  
} 

And I think on a Wep Page the aproach could be the same.

Good Luck!

I can see what @Þaw mentioned :

$ENROLLEES = $this->load->database('ENROLLEES', TRUE);
$ACCOUNTS = $this->load->database('ACCOUNTS', TRUE);

CodeIgniter supports multiple databases. You need to keep both database reference in separate variable as you did above. So far you are right/correct.

Next you need to use them as below:

$ENROLLEES->query();
$ENROLLEES->result();

and

$ACCOUNTS->query();
$ACCOUNTS->result();

Instead of using

$this->db->query();
$this->db->result();

See this for reference: http://ellislab.com/codeigniter/user-guide/database/connecting.html

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

slightly off-topic (using the CLI instead of PHP), but still worth knowing: You can set the prompt to display the default database by using any of the following

mysql --prompt='\d> '
export MYSQL_PS1='\d> '

or once inside

prompt \d>\_
\R \d>\_

Using this.props.children is the idiomatic way to pass instantiated components to a react component

const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>

When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div or span):

const Label = props => <span>{props.children}</span>
const Button = props => {
    const Inner = props.inner; // Note: variable name _must_ start with a capital letter 
    return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>

If what you want to do is to pass a children-like parameter as a prop, you can do that:

const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />

After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.

String contents = FileUtils.readFileToString(new File("/path/to/the/file"), "UTF-8")

You can see de javadoc for the method for details.

If a non-static method is member of a class, you have to define it like that:

def Method(self, atributes..)

So, I suppose your 'e' is instance of some class with implemented method that tries to execute and has too much arguments.

    # @return a strings
    def addBinary(self, A, B):
        num1 = bin(int(A, 2))
        num2 = bin(int(B, 2))
        bin_str = bin(int(num1, 2)+int(num2, 2))
        b_index = bin_str.index('b')
        return bin_str[b_index+1:]

s = Solution()
print(s.addBinary("11", "100"))

Just a note here that you may actually be better off having 3 separate SELECTS for reasons of optimization. If you have one single SELECT then the generated plan will have to project all columns col1, col2, col3, col7, col8 etc, although, depending on the value of the runtime @var, only some are needed. This may result in plans that do unnecessary clustered index lookups because the non-clustered index Doesn't cover all columns projected by the SELECT.

On the other hand 3 separate SELECTS, each projecting the needed columns only may benefit from non-clustered indexes that cover just your projected column in each case.

Of course this depends on the actual schema of your data model and the exact queries, but this is just a heads up so you don't bring the imperative thinking mind frame of procedural programming to the declarative world of SQL.

There are two ways to do this:

1. in stead of using user._id use user.id and it will return a string for you
2. If you really want to go the long way around you can use user._id.toString()

This is an interesting question, and I started thinking about how I would implement something like this.

I came up with this (fiddle);

Basically, instead of trying to call a directive from a controller, I created a module to house all the popdown logic:

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

I put two things in the module, a factory for the API which can be injected anywhere, and the directive for defining the behavior of the actual popdown element:

The factory just defines a couple of functions success and error and keeps track of a couple of variables:

PopdownModule.factory('PopdownAPI', function() {
    return {
        status: null,
        message: null,
        success: function(msg) {
            this.status = 'success';
            this.message = msg;
        },
        error: function(msg) {
            this.status = 'error';
            this.message = msg;
        },
        clear: function() {
            this.status = null;
            this.message = null;
        }
    }
});

The directive gets the API injected into its controller, and watches the api for changes (I'm using bootstrap css for convenience):

PopdownModule.directive('popdown', function() {
    return {
        restrict: 'E',
        scope: {},
        replace: true,
        controller: function($scope, PopdownAPI) {
            $scope.show = false;
            $scope.api = PopdownAPI;

            $scope.$watch('api.status', toggledisplay)
            $scope.$watch('api.message', toggledisplay)

            $scope.hide = function() {
                $scope.show = false;
                $scope.api.clear();
            };

            function toggledisplay() {
                $scope.show = !!($scope.api.status && $scope.api.message);               
            }
        },
        template: '<div class="alert alert-{{api.status}}" ng-show="show">' +
                  '  <button type="button" class="close" ng-click="hide()">&times;</button>' +
                  '  {{api.message}}' +
                  '</div>'
    }
})

Then I define an app module that depends on Popdown:

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

app.controller('main', function($scope, PopdownAPI) {
    $scope.success = function(msg) { PopdownAPI.success(msg); }
    $scope.error   = function(msg) { PopdownAPI.error(msg); }
});

And the HTML looks like:

<html ng-app="app">
    <body ng-controller="main">
        <popdown></popdown>
        <a class="btn" ng-click="success('I am a success!')">Succeed</a>
        <a class="btn" ng-click="error('Alas, I am a failure!')">Fail</a>
    </body>
</html>

I'm not sure if it's completely ideal, but it seemed like a reasonable way to set up communication with a global-ish popdown directive.

Again, for reference, the fiddle.

Recent versions of Firefox support a policies.json file that will be applied to all Firefox profiles.

For CA certificates, you have some options, here's one example, tested with Linux/Ubuntu where I already have system-wide CA certs in /usr/local/share/ca-certificates:

In /usr/lib/firefox/distribution/policies.json

{
    "policies": {
        "Certificates": {
            "Install": [
                "/usr/local/share/ca-certificates/my-custom-root-ca.crt"
            ]
        }
    }
}

Support for Thunderbird is on its way.

Pretty generic UIAlertController extension for all cases of UINavigationController and/or UITabBarController. Also works if there's a modal VC on screen at the moment.

Usage:

//option 1:
myAlertController.show()
//option 2:
myAlertController.present(animated: true) {
    //completion code...
}

This is the extension:

//Uses Swift1.2 syntax with the new if-let
// so it won't compile on a lower version.
extension UIAlertController {

    func show() {
        present(animated: true, completion: nil)
    }

    func present(#animated: Bool, completion: (() -> Void)?) {
        if let rootVC = UIApplication.sharedApplication().keyWindow?.rootViewController {
            presentFromController(rootVC, animated: animated, completion: completion)
        }
    }

    private func presentFromController(controller: UIViewController, animated: Bool, completion: (() -> Void)?) {
        if  let navVC = controller as? UINavigationController,
            let visibleVC = navVC.visibleViewController {
                presentFromController(visibleVC, animated: animated, completion: completion)
        } else {
          if  let tabVC = controller as? UITabBarController,
              let selectedVC = tabVC.selectedViewController {
                presentFromController(selectedVC, animated: animated, completion: completion)
          } else {
              controller.presentViewController(self, animated: animated, completion: completion)
          }
        }
    }
}

I've done this kind of thing with a form that contains a TextBox.

So if you wanted to put this in say cell H1, then use:

ActiveSheet.Range("H1").Value = txtBoxName.Text

there are several ways. You can use this method:

start = @selected_date.beginning_of_day
end = @selected_date.end_of_day
@comments = Comment.where("DATE(created_at) BETWEEN ? AND ?", start, end)

Or this:

@comments = Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day)

Just run .exe file in dependency walker( http://dependencywalker.com/) and it will point you the missing dlls and download those dll (www.dll-files.com) and paste in the c:windows:system32 and the folder as your .exe and even provide the path of those dll in path variable.

    //source    
    public async Task<string> methodName()
            {
             return Data;
             }

    //Consumption
     methodName().Result;

Hope this helps :)

The following worked for me:

$(':input').val('');

However, it is submitting the form, so it might not be what you are looking for.

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

And what does "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.5 Safari/535.19" means ?

This is the value of User-Agent, the browser identification string.

For this reason, most Web browsers use a User-Agent string value as follows:

Mozilla/[version] ([system and browser information]) [platform] ([platform details]) [extensions]. For example, Safari on the iPad has used the following:

Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Mobile/7B405 The components of this string are as follows:

Mozilla/5.0: Previously used to indicate compatibility with the Mozilla rendering engine. (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us): Details of the system in which the browser is running. AppleWebKit/531.21.10: The platform the browser uses. (KHTML, like Gecko): Browser platform details. Mobile/7B405: This is used by the browser to indicate specific enhancements that are available directly in the browser or through third parties. An example of this is Microsoft Live Meeting which registers an extension so that the Live Meeting service knows if the software is already installed, which means it can provide a streamlined experience to joining meetings.

This value will be used to identify what browser is being used by end user.

Old school of doing things by hand has always been good for me.

1. Clean the select and leave the first option:

       $('#your_select_id').find('option').remove()
       .end().append('<option value="0">Selec...</option>')
       .val('whatever');
   

2. If your data comes from a Json or whatever (just Concat the data):

       var JSONObject = JSON.parse(data);
       newOptionsSelect = '';
       for (var key in JSONObject) {
           if (JSONObject.hasOwnProperty(key)) {
               var newOptionsSelect = newOptionsSelect + '<option value="'+JSONObject[key]["value"]+'">'+JSONObject[key]["text"]+'</option>';
           }
       }
   
       $('#your_select_id').append( newOptionsSelect );
   

3. My Json Objetc:

       [{"value":1,"text":"Text 1"},{"value":2,"text":"Text 2"},{"value":3,"text":"Text 3"}]
   

This solution is ideal for working with Ajax, and answers in Json from a database.

Can't you style the forms themselves? Then, style the divs accordingly.

form
{
    /* styles */
}

You can always overrule inherited styles by making it important:

form
{
    /* styles */ !important
}

The "adjustment" in adjusted R-squared is related to the number of variables and the number of observations.

If you keep adding variables (predictors) to your model, R-squared will improve - that is, the predictors will appear to explain the variance - but some of that improvement may be due to chance alone. So adjusted R-squared tries to correct for this, by taking into account the ratio (N-1)/(N-k-1) where N = number of observations and k = number of variables (predictors).

It's probably not a concern in your case, since you have a single variate.

Here's technique I figured out after a bit of trial and error that allows you to preserve your XML styles and avoid the issues of using a <merge/> (i.e. inflate() requires a merge to attach to root, and returns the root node). No runtime new TableRow()s or new TextView()s required.

Code

Note: Here CheckBalanceActivity is some sample Activity class

TableLayout table = (TableLayout)CheckBalanceActivity.this.findViewById(R.id.attrib_table);
for(ResourceBalance b : xmlDoc.balance_info)
{
    // Inflate your row "template" and fill out the fields.
    TableRow row = (TableRow)LayoutInflater.from(CheckBalanceActivity.this).inflate(R.layout.attrib_row, null);
    ((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME);
    ((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE);
    table.addView(row);
}
table.requestLayout();     // Not sure if this is needed.

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

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

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

panel1.CssClass = "classname";

Your problem with Vim is that you don't grok vi.

You mention cutting with yy and complain that you almost never want to cut whole lines. In fact programmers, editing source code, very often want to work on whole lines, ranges of lines and blocks of code. However, yy is only one of many way to yank text into the anonymous copy buffer (or "register" as it's called in vi).

The "Zen" of vi is that you're speaking a language. The initial y is a verb. The statement yy is a synonym for y_. The y is doubled up to make it easier to type, since it is such a common operation.

This can also be expressed as dd P (delete the current line and paste a copy back into place; leaving a copy in the anonymous register as a side effect). The y and d "verbs" take any movement as their "subject." Thus yW is "yank from here (the cursor) to the end of the current/next (big) word" and y'a is "yank from here to the line containing the mark named 'a'."

If you only understand basic up, down, left, and right cursor movements then vi will be no more productive than a copy of "notepad" for you. (Okay, you'll still have syntax highlighting and the ability to handle files larger than a piddling ~45KB or so; but work with me here).

vi has 26 "marks" and 26 "registers." A mark is set to any cursor location using the m command. Each mark is designated by a single lower case letter. Thus ma sets the 'a' mark to the current location, and mz sets the 'z' mark. You can move to the line containing a mark using the ' (single quote) command. Thus 'a moves to the beginning of the line containing the 'a' mark. You can move to the precise location of any mark using the ` (backquote) command. Thus `z will move directly to the exact location of the 'z' mark.

Because these are "movements" they can also be used as subjects for other "statements."

So, one way to cut an arbitrary selection of text would be to drop a mark (I usually use 'a' as my "first" mark, 'z' as my next mark, 'b' as another, and 'e' as yet another (I don't recall ever having interactively used more than four marks in 15 years of using vi; one creates one's own conventions regarding how marks and registers are used by macros that don't disturb one's interactive context). Then we go to the other end of our desired text; we can start at either end, it doesn't matter. Then we can simply use d`a to cut or y`a to copy. Thus the whole process has a 5 keystrokes overhead (six if we started in "insert" mode and needed to Esc out command mode). Once we've cut or copied then pasting in a copy is a single keystroke: p.

I say that this is one way to cut or copy text. However, it is only one of many. Frequently we can more succinctly describe the range of text without moving our cursor around and dropping a mark. For example if I'm in a paragraph of text I can use { and } movements to the beginning or end of the paragraph respectively. So, to move a paragraph of text I cut it using { d} (3 keystrokes). (If I happen to already be on the first or last line of the paragraph I can then simply use d} or d{ respectively.

The notion of "paragraph" defaults to something which is usually intuitively reasonable. Thus it often works for code as well as prose.

Frequently we know some pattern (regular expression) that marks one end or the other of the text in which we're interested. Searching forwards or backwards are movements in vi. Thus they can also be used as "subjects" in our "statements." So I can use d/foo to cut from the current line to the next line containing the string "foo" and y?bar to copy from the current line to the most recent (previous) line containing "bar." If I don't want whole lines I can still use the search movements (as statements of their own), drop my mark(s) and use the `x commands as described previously.

In addition to "verbs" and "subjects" vi also has "objects" (in the grammatical sense of the term). So far I've only described the use of the anonymous register. However, I can use any of the 26 "named" registers by prefixing the "object" reference with " (the double quote modifier). Thus if I use "add I'm cutting the current line into the 'a' register and if I use "by/foo then I'm yanking a copy of the text from here to the next line containing "foo" into the 'b' register. To paste from a register I simply prefix the paste with the same modifier sequence: "ap pastes a copy of the 'a' register's contents into the text after the cursor and "bP pastes a copy from 'b' to before the current line.

This notion of "prefixes" also adds the analogs of grammatical "adjectives" and "adverbs' to our text manipulation "language." Most commands (verbs) and movement (verbs or objects, depending on context) can also take numeric prefixes. Thus 3J means "join the next three lines" and d5} means "delete from the current line through the end of the fifth paragraph down from here."

This is all intermediate level vi. None of it is Vim specific and there are far more advanced tricks in vi if you're ready to learn them. If you were to master just these intermediate concepts then you'd probably find that you rarely need to write any macros because the text manipulation language is sufficiently concise and expressive to do most things easily enough using the editor's "native" language.

A sampling of more advanced tricks:

There are a number of : commands, most notably the :% s/foo/bar/g global substitution technique. (That's not advanced but other : commands can be). The whole : set of commands was historically inherited by vi's previous incarnations as the ed (line editor) and later the ex (extended line editor) utilities. In fact vi is so named because it's the visual interface to ex.

: commands normally operate over lines of text. ed and ex were written in an era when terminal screens were uncommon and many terminals were "teletype" (TTY) devices. So it was common to work from printed copies of the text, using commands through an extremely terse interface (common connection speeds were 110 baud, or, roughly, 11 characters per second -- which is slower than a fast typist; lags were common on multi-user interactive sessions; additionally there was often some motivation to conserve paper).

So the syntax of most : commands includes an address or range of addresses (line number) followed by a command. Naturally one could use literal line numbers: :127,215 s/foo/bar to change the first occurrence of "foo" into "bar" on each line between 127 and 215. One could also use some abbreviations such as . or $ for current and last lines respectively. One could also use relative prefixes + and - to refer to offsets after or before the curent line, respectively. Thus: :.,$j meaning "from the current line to the last line, join them all into one line". :% is synonymous with :1,$ (all the lines).

The :... g and :... v commands bear some explanation as they are incredibly powerful. :... g is a prefix for "globally" applying a subsequent command to all lines which match a pattern (regular expression) while :... v applies such a command to all lines which do NOT match the given pattern ("v" from "conVerse"). As with other ex commands these can be prefixed by addressing/range references. Thus :.,+21g/foo/d means "delete any lines containing the string "foo" from the current one through the next 21 lines" while :.,$v/bar/d means "from here to the end of the file, delete any lines which DON'T contain the string "bar."

It's interesting that the common Unix command grep was actually inspired by this ex command (and is named after the way in which it was documented). The ex command :g/re/p (grep) was the way they documented how to "globally" "print" lines containing a "regular expression" (re). When ed and ex were used, the :p command was one of the first that anyone learned and often the first one used when editing any file. It was how you printed the current contents (usually just one page full at a time using :.,+25p or some such).

Note that :% g/.../d or (its reVerse/conVerse counterpart: :% v/.../d are the most common usage patterns. However there are couple of other ex commands which are worth remembering:

We can use m to move lines around, and j to join lines. For example if you have a list and you want to separate all the stuff matching (or conversely NOT matching some pattern) without deleting them, then you can use something like: :% g/foo/m$ ... and all the "foo" lines will have been moved to the end of the file. (Note the other tip about using the end of your file as a scratch space). This will have preserved the relative order of all the "foo" lines while having extracted them from the rest of the list. (This would be equivalent to doing something like: 1G!GGmap!Ggrep foo<ENTER>1G:1,'a g/foo'/d (copy the file to its own tail, filter the tail through grep, and delete all the stuff from the head).

To join lines usually I can find a pattern for all the lines which need to be joined to their predecessor (all the lines which start with "^ " rather than "^ * " in some bullet list, for example). For that case I'd use: :% g/^ /-1j (for every matching line, go up one line and join them). (BTW: for bullet lists trying to search for the bullet lines and join to the next doesn't work for a couple reasons ... it can join one bullet line to another, and it won't join any bullet line to all of its continuations; it'll only work pairwise on the matches).

Almost needless to mention you can use our old friend s (substitute) with the g and v (global/converse-global) commands. Usually you don't need to do so. However, consider some case where you want to perform a substitution only on lines matching some other pattern. Often you can use a complicated pattern with captures and use back references to preserve the portions of the lines that you DON'T want to change. However, it will often be easier to separate the match from the substitution: :% g/foo/s/bar/zzz/g -- for every line containing "foo" substitute all "bar" with "zzz." (Something like :% s/\(.*foo.*\)bar\(.*\)/\1zzz\2/g would only work for the cases those instances of "bar" which were PRECEDED by "foo" on the same line; it's ungainly enough already, and would have to be mangled further to catch all the cases where "bar" preceded "foo")

The point is that there are more than just p, s, and d lines in the ex command set.

The : addresses can also refer to marks. Thus you can use: :'a,'bg/foo/j to join any line containing the string foo to its subsequent line, if it lies between the lines between the 'a' and 'b' marks. (Yes, all of the preceding ex command examples can be limited to subsets of the file's lines by prefixing with these sorts of addressing expressions).

That's pretty obscure (I've only used something like that a few times in the last 15 years). However, I'll freely admit that I've often done things iteratively and interactively that could probably have been done more efficiently if I'd taken the time to think out the correct incantation.

Another very useful vi or ex command is :r to read in the contents of another file. Thus: :r foo inserts the contents of the file named "foo" at the current line.

More powerful is the :r! command. This reads the results of a command. It's the same as suspending the vi session, running a command, redirecting its output to a temporary file, resuming your vi session, and reading in the contents from the temp. file.

Even more powerful are the ! (bang) and :... ! (ex bang) commands. These also execute external commands and read the results into the current text. However, they also filter selections of our text through the command! This we can sort all the lines in our file using 1G!Gsort (G is the vi "goto" command; it defaults to going to the last line of the file, but can be prefixed by a line number, such as 1, the first line). This is equivalent to the ex variant :1,$!sort. Writers often use ! with the Unix fmt or fold utilities for reformating or "word wrapping" selections of text. A very common macro is {!}fmt (reformat the current paragraph). Programmers sometimes use it to run their code, or just portions of it, through indent or other code reformatting tools.

Using the :r! and ! commands means that any external utility or filter can be treated as an extension of our editor. I have occasionally used these with scripts that pulled data from a database, or with wget or lynx commands that pulled data off a website, or ssh commands that pulled data from remote systems.

Another useful ex command is :so (short for :source). This reads the contents of a file as a series of commands. When you start vi it normally, implicitly, performs a :source on ~/.exinitrc file (and Vim usually does this on ~/.vimrc, naturally enough). The use of this is that you can change your editor profile on the fly by simply sourcing in a new set of macros, abbreviations, and editor settings. If you're sneaky you can even use this as a trick for storing sequences of ex editing commands to apply to files on demand.

For example I have a seven line file (36 characters) which runs a file through wc, and inserts a C-style comment at the top of the file containing that word count data. I can apply that "macro" to a file by using a command like: vim +'so mymacro.ex' ./mytarget

(The + command line option to vi and Vim is normally used to start the editing session at a given line number. However it's a little known fact that one can follow the + by any valid ex command/expression, such as a "source" command as I've done here; for a simple example I have scripts which invoke: vi +'/foo/d|wq!' ~/.ssh/known_hosts to remove an entry from my SSH known hosts file non-interactively while I'm re-imaging a set of servers).

Usually it's far easier to write such "macros" using Perl, AWK, sed (which is, in fact, like grep a utility inspired by the ed command).

The @ command is probably the most obscure vi command. In occasionally teaching advanced systems administration courses for close to a decade I've met very few people who've ever used it. @ executes the contents of a register as if it were a vi or ex command.
Example: I often use: :r!locate ... to find some file on my system and read its name into my document. From there I delete any extraneous hits, leaving only the full path to the file I'm interested in. Rather than laboriously Tab-ing through each component of the path (or worse, if I happen to be stuck on a machine without Tab completion support in its copy of vi) I just use:

1. 0i:r (to turn the current line into a valid :r command),
2. "cdd (to delete the line into the "c" register) and
3. @c execute that command.

That's only 10 keystrokes (and the expression "cdd @c is effectively a finger macro for me, so I can type it almost as quickly as any common six letter word).

A sobering thought

I've only scratched to surface of vi's power and none of what I've described here is even part of the "improvements" for which vim is named! All of what I've described here should work on any old copy of vi from 20 or 30 years ago.

There are people who have used considerably more of vi's power than I ever will.

We use Maven (Ant's big brother) for all our java projects, and it has a very nifty WAR plugin. Tutorials and usage can be found there.

It's a lot easier than Ant, fully compatible with Eclipse (use maven eclipse:eclipse to create Eclipse projects) and easy to configure.

I had this issue, jquery URL was valid, everything looked good and validation still worked. After a hard refresh CTL+F5 the error went away in Chrome.

This looks like you have to enable .htaccess by adding this to your vhost:

<Directory /var/www/html/public/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

If that doesn't work, make sure you have mod_rewrite enabled.

Don't forget to restart apache after making the changes! (service apache2 restart)

Strings in C# are immutable and in some sense it means that they are fixed-size.
However you cannot constrain a string variable to only accept n-character strings. If you define a string variable, it can be assigned any string. If truncating strings (or throwing errors) is essential part of your business logic, consider doing so in your specific class' property setters (that's what Jon suggested, and it's the most natural way of creating constraints on values in .NET).

If you just want to make sure isn't too long (e.g. when passing it as a parameter to some legacy code), truncate it manually:

const int MaxLength = 5;


var name = "Christopher";
if (name.Length > MaxLength)
    name = name.Substring(0, MaxLength); // name = "Chris"

I had the same problem, but while using a library project. The issue has been solved in r17: Instead of using the package's namespace:

xmlns:app="http://schemas.android.com/apk/res/hu.droidium.exercises"

One has to use a dummy namespace:

xmlns:app="http://schemas.android.com/apk/res-auto"

This will fix the problem of the attributes not being accessible from the referencing project.

Another option is using eval and parse, as in

d = 5
for (i in 1:10){
     eval(parse(text = paste('a', 1:10, ' = d + rnorm(3)', sep='')[i]))
}

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

I am not clear exactly what your situation requires but the following may get you started. The key here is using ThisWorkbook.Path to get a relative file path:

Sub SaveToRelativePath()
    Dim relativePath As String
    relativePath = ThisWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name
    ActiveWorkbook.SaveAs Filename:=relativePath
End Sub

You can't use IF like that. You can do what you want with AND and OR:

SELECT t.first_name,
       t.last_name,
       t.employid,
       t.status
  FROM employeetable t
 WHERE ((status_flag = STATUS_ACTIVE   AND t.status = 'A')
     OR (status_flag = STATUS_INACTIVE AND t.status = 'T')
     OR (source_flag = SOURCE_FUNCTION AND t.business_unit = 'production')
     OR (source_flag = SOURCE_USER     AND t.business_unit = 'users'))
   AND t.first_name LIKE firstname
   AND t.last_name  LIKE lastname
   AND t.employid   LIKE employeeid;

Use Date.Now instead of DateTime.Now

Get Screenshot From View :

- (UIImage *)takeSnapshotView {
    CGRect rect = [myView bounds];//Here you can change your view with myView
    UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [myView.layer renderInContext:context];
    UIImage *capturedScreen = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return capturedScreen;//capturedScreen is the image of your view
}

Hope, this is what you're looking for. Any concern get back to me. :)

It may also happen in the following case:

eg. if we consider the push function of a stack:

typedef struct stack
{
    int a[20];
    int head;
}stack;

void push(stack **s)
{
    int data;
    printf("Enter data:");
    scanf("%d",&(*s->a[++*s->head])); /* this is where the error is*/
}

main()
{
    stack *s;
    s=(stack *)calloc(1,sizeof(stack));
    s->head=-1;
    push(&s);
    return 0;
}

The error is in the push function and in the commented line. The pointer s has to be included within the parentheses. The correct code:

scanf("%d",&( (*s)->a[++(*s)->head]));

This behavior is introduced in all major Tomcat releases:

• Tomcat 7.0.73, 8.0.39, 8.5.7

To fix, do one of the following:

• set relaxedQueryChars to allow this character (recommended, see Lincoln's answer)
• set requestTargetAllow option (deprecated in Tomcat 8.5) (see Jérémie's answer).
• you can downgrade to one of older versions (not recommended - security)

Based on changelog, those changes could affect this behavior:

Tomcat 8.5.3:

Ensure that requests with HTTP method names that are not tokens (as required by RFC 7231) are rejected with a 400 response

Tomcat 8.5.7:

Add additional checks for valid characters to the HTTP request line parsing so invalid request lines are rejected sooner.

The best option (following the standard) - you want to encode your URL on client:

encodeURI("http://localhost:8080/app/handleResponse?msg=name|id|")
> http://localhost:8080/app/handleResponse?msg=name%7Cid%7C

or just query string:

encodeURIComponent("msg=name|id|")
> msg%3Dname%7Cid%7C

It will secure you from other problematic characters (list of invalid URI characters).

Not all versions of sed understand \t. Just insert a literal tab instead (press Ctrl-V then Tab).

'Select non blank cells
Selection.SpecialCells(xlCellTypeConstants, 23).Select
' REplace tehse blank look like cells to something uniqu
Selection.Replace What:="", Replacement:="TOBEDELETED", LookAt:=xlWhole, _
    SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
    ReplaceFormat:=False
'now replace this uique text to nothing and voila all will disappear
Selection.Replace What:="TOBEDELETED", Replacement:="", LookAt:=xlWhole, _
    SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
    ReplaceFormat:=False

Most common reason for such problems are

1.If you have defined the jquery library more than once.

<script type="text/javascript" src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

    <div class="modal fade" id="myModal" aria-hidden="true">
    ...
    ...
    </div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>

The bootstrap library gets applied to the first jquery library but when you reload the jquery library, the original bootstrap load is lost(Modal function is in bootstrap).

2.Please wrap your JavaScript code inside

$(document).ready(function(){});

3.Please check if the id of the modal is same

as the one you have defined for the component(Also check for duplication's of same id ).

SELECT DATEDIFF(day,'2014-06-05','2014-08-05') AS DiffDate

diffdate is column name.

sizeof str is 7 - five bytes for the "Hello" text, plus the explicit NUL terminator, plus the implicit NUL terminator.

strlen(str) is 5 - the five "Hello" bytes only.

The key here is that the implicit nul terminator is always added - even if the string literal just happens to end with \0. Of course, strlen just stops at the first \0 - it can't tell the difference.

There is one exception to the implicit NUL terminator rule - if you explicitly specify the array size, the string will be truncated to fit:

char str[6] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 6 (with one NUL)
char str[7] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 7 (with two NULs)
char str[8] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 8 (with three NULs per C99 6.7.8.21)

This is, however, rarely useful, and prone to miscalculating the string length and ending up with an unterminated string. It is also forbidden in C++.

If anyone is working a project which is synced via Subversion and this still happening, I think this can slow the process of workflow in Android Studio. For example if it work very slow while: scrolling in a class,xml etc, while my app is still running on my device.

• Go to Version Control at Preferences, and set from Subversion to None.

In addition to the other functions suggested above, if you like lambdas:

invert = lambda mydict: {v:k for k, v in mydict.items()}

Or, you could do it this way too:

invert = lambda mydict: dict( zip(mydict.values(), mydict.keys()) )

That's a bit of informal terminology.

As far as Git is concerned, every other repository is just a remote.

Generally speaking, upstream is where you cloned from (the origin). Downstream is any project that integrates your work with other works.

The terms are not restricted to Git repositories.

For instance, Ubuntu is a Debian derivative, so Debian is upstream for Ubuntu.

What database are you on? With MS SQL Server, it's a database-wide setting, or you can over-ride it per-query with the COLLATE keyword.

.nav ul li a#nav-ask{
    display:none;
}

all of you guys didn't mention a case where someone "like me" would install django befor installing virtualenv...so for all the people of my kind ther if you did that...reinstall django after activating the virtualenv..i hope this helps

Use the Boost C++ libraries. There is a CRC included there and the license is good.

You've got an unclosed quote, brace, bracket, if, loop, or something.

If you can't see it just by looking (I'd recommend a syntax colouring editor and a neat indentation style), take a copy of the script, and delete half of it, cutting it of somewhere that ought to be valid. If the script runs, as far as it can, then the problem is in the other half. Repeat until you've narrowed down the problem.

Necromancing.
It looks you have just as good a schema to work with as me... Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE

END 

No one mentioned this, but in conjunction to the other responses, you can also get the apk file from your bin directory to your phone or tablet by putting it on a web site and just downloading it.

Your device will complain about installing it after you download it. Your device will advise you or a risk of installing programs from unknown sources and give you the option to bypass the advice.

Your question is very specific. You don't have to pull it from your emulator, just grab the apk file from the bin folder in your project and place it on your real device.

Most people are giving you valuable information for the next step (signing and publishing your apk), you are not required to do that step to get it on your real device.

Downloading it to your real device is a simple method.

I just tested this- both CTE and non-CTE (where the query was typed out for every union instance) both took ~31 seconds. CTE made the code much more readable though- cut it down from 241 to 130 lines which is very nice. Temp table on the other hand cut it down to 132 lines, and took FIVE SECONDS to run. No joke. all of this testing was cached- the queries were all run multiple times before.

I solved the problem by cat'ing all the pems together:

cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD

(keytool didn't know what to do with a PKCS7 formatted key)

I got all the pems from letsencrypt

In my case it was from "Automatic Backlink Checker" extension. Maybe this will help some other users to fix their problem easier. I went from disabling all of the extensions at once to disabling them one by one. This way the mole.

Depending on the version of Windows you might find the use of the "Choice" option to be helpful. It is not supported in most if not all x64 versions as far as I can tell. A handy substitution called Choice.vbs along with examples of use can be found on SourceForge under the name Choice.zip

We're all working around some old bugs that haven't been fixed likely because it's "by design." I ran into the freezing problem @iwasrobbed described elsewhere when trying to nil the interactivePopGestureRecognizer's delegate which seemed like it should've worked. If you want swipe behavior reconsider using backBarButtonItem which you can customize.

I also ran into interactivePopGestureRecognizer not working when the UINavigationBar is hidden. If hiding the navigation bar is a concern for you, reconsider your design before implementing a workaround for a bug.

I had to use strcpy_s and it worked.

#include "stdafx.h"
#include<iostream>
#include<string>

using namespace std;

struct student
{
    char name[30];
    int age;
};

int main()
{

    struct student s1;
    char myname[30] = "John";
    strcpy_s (s1.name, strlen(myname) + 1 ,myname );
    s1.age = 21;

    cout << " Name: " << s1.name << " age: " << s1.age << endl;
    return 0;
}

A note for people who created the local copy on Windows and want to create a corresponding remote repository on a Unix-line system, where text files get LF endings on further clones by developers on Unix-like systems, but CRLF endings on Windows.

If you created your Windows repository before setting up line-ending translation then you have a problem. Git's default setting is no translation, so your working set uses CRLF but your repository (i.e. the data stored under .git) has saved the files as CRLF too.

When you push to the remote, the saved files are copied as-is, no line ending translation occurs. (Line ending translation occurs when files are commited to a repository, not when repositories are pushed). You end up with CRLF in your Unix-like repository, which is not what you want.

To get LF in the remote repository you have to make sure LF is in the local repository first, by re-normalizing your Windows repository. This will have no visible effect on your Windows working set, which still has CRLF endings, however when you push to remote, the remote will get LF correctly.

I'm not sure if there's an easy way to tell what line endings you have in your Windows repository - I guess you could test it by setting core.autocrlf=false and then cloning (If the repo has LF endings, the clone will have LF too).

Double check that the foreign keys have exactly the same type as the field you've got in this table. For example, both should be Integer(10), or Varchar (8), even the number of characters.

One simplistic approach to measuring the "elapsed time" between events is to just grab the current date and time.

In SQL Server Management Studio

SELECT GETDATE();
SELECT /* query one */ 1 ;
SELECT GETDATE();
SELECT /* query two */ 2 ; 
SELECT GETDATE(); 

To calculate elapsed times, you could grab those date values into variables, and use the DATEDIFF function:

DECLARE @t1 DATETIME;
DECLARE @t2 DATETIME;

SET @t1 = GETDATE();
SELECT /* query one */ 1 ;
SET @t2 = GETDATE();
SELECT DATEDIFF(millisecond,@t1,@t2) AS elapsed_ms;

SET @t1 = GETDATE();
SELECT /* query two */ 2 ;
SET @t2 = GETDATE();
SELECT DATEDIFF(millisecond,@t1,@t2) AS elapsed_ms;

That's just one approach. You can also get elapsed times for queries using SQL Profiler.

You can use SSH and SFTP as suggested here.

1. In the Guest OS (Mac OS X), open System Preferences > Sharing, then activate Remote Login; note the ip address specified in the Remote Login instructions, e.g. ssh [email protected]
2. In VirtualBox, open Devices > Network > Network Settings > Advanced > Port Forwarding and specify Host IP = 127.0.0.1, Host Port 2222, Guest IP 10.0.2.15, Guest Port 22
3. On the Host OS, run the following command sftp -P 2222 [email protected]; if you prefer a graphical interface, you can use FileZilla

Replace user and 10.0.2.15 with the appropriate values relevant to your configuration.

What you really want to do is bind the event handler for the capture phase of the event. However, that isn't supported in IE as far as I know, so that might not be all that useful.
