I Using below simple way to create a project 1- First in a directory that desire to make it project, create a .project file with below contents:

<projectDescription>
    <name>Project-Name</name>
    <comment></comment>
    <projects>
    </projects>
    <buildSpec>
    </buildSpec>
    <natures>
    </natures>
</projectDescription>

2- Now instead of "Project-Name", write your project name, maybe current directory name

3- Now save this file to directory that desire to make that directory as project with name ".project" ( for save like this, use Notepad )

4- Now go to Eclips and open project and add your files to it.

Your Activity is receiving the callback as must have used:

mViewPagerCloth.setOnClickListener((YourActivityName)getActivity());

If you want your fragment to receive callback then do this:

mViewPagerCloth.setOnClickListener(this);

and implement onClickListener interface on Fragment

Here's some code that'll substitute for the blink tag

<p id="blink">This text will blink!</p>
<script>
var blacktime = 1000;
var whitetime = 1000;
//These can be as long as you desire in milliseconds
setTimeout(whiteFunc,blacktime);
function whiteFunc(){
    document.getElementById("blink").style.color = "white";
    setTimeout(blackFunc,whitetime);
}
function blackFunc(){
    document.getElementById("blink").style.color = "black";
    setTimeout(whiteFunc,blacktime);
}
</script>

You should consider using layer-list

Create a drawable file like this, name it as ic_calendar.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <solid android:color="@android:color/transparent"/>
    </shape>
</item>
<item android:right="10dp">
    <bitmap android:gravity="center_vertical|left"
        android:src="@drawable/ic_calendar_16dp"
        android:tint="@color/red"
        />
</item>
</layer-list>

Under layout file,

<TextView
         android:id="@+id/tvDate"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:drawableLeft="@drawable/ic_calendar"
         android:textColor="@color/colorGrey"
         android:textSize="14sp" 
    />

XML_HTMLSax is rather stable - even if it's not maintained any more. Another option could be to pipe you HTML through Html Tidy and then parse it with standard XML tools.

add:

Chart.defaults.global.legend.display = false;

in the starting of your script code;

You can't do this within the Python program, because the shell decides which version to use if you a shebang line.

If you aren't using a shell with a shebang line and just type python myprogram.py it uses the default version unless you decide specifically which Python version when you type pythonXXX myprogram.py which version to use.

Once your Python program is running you have already decided which Python executable to use to get the program running.

virtualenv is for segregating python versions and environments, it specifically exists to eliminate conflicts.

git pull --rebase origin/master 

is a single command that can help you most of the time.

Edit: Pulls the commits from the origin/master and applies your changes upon the newly pulled branch history.

For a Spark execution in pyspark two components are required to work together:

• pyspark python package
• Spark instance in a JVM

When launching things with spark-submit or pyspark, these scripts will take care of both, i.e. they set up your PYTHONPATH, PATH, etc, so that your script can find pyspark, and they also start the spark instance, configuring according to your params, e.g. --master X

Alternatively, it is possible to bypass these scripts and run your spark application directly in the python interpreter likepython myscript.py. This is especially interesting when spark scripts start to become more complex and eventually receive their own args.

1. Ensure the pyspark package can be found by the Python interpreter. As already discussed either add the spark/python dir to PYTHONPATH or directly install pyspark using pip install.
2. Set the parameters of spark instance from your script (those that used to be passed to pyspark).
   • For spark configurations as you'd normally set with --conf they are defined with a config object (or string configs) in SparkSession.builder.config
   • For main options (like --master, or --driver-mem) for the moment you can set them by writing to the PYSPARK_SUBMIT_ARGS environment variable. To make things cleaner and safer you can set it from within Python itself, and spark will read it when starting.
3. Start the instance, which just requires you to call getOrCreate() from the builder object.

Your script can therefore have something like this:

from pyspark.sql import SparkSession

if __name__ == "__main__":
    if spark_main_opts:
        # Set main options, e.g. "--master local[4]"
        os.environ['PYSPARK_SUBMIT_ARGS'] = spark_main_opts + " pyspark-shell"

    # Set spark config
    spark = (SparkSession.builder
             .config("spark.checkpoint.compress", True)
             .config("spark.jars.packages", "graphframes:graphframes:0.5.0-spark2.1-s_2.11")
             .getOrCreate())

Sometimes, you need to list the variables of an object and not for debugging purposes. The right way to do it is using get_object_vars($object). It returns an array that has all the class variables and their value. You can then loop through them in a foreach loop. If used within the object itself, simply do get_object_vars($this)

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files.

Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.

See the documentation here.

There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
     "*.h"
     "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})

Note that this requires manual re-running of cmake if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.

As of CMake 3.12, you can pass the CONFIGURE_DEPENDS flag to file(GLOB to automatically check and reset the file lists any time the build is invoked. You would write:

cmake_minimum_required(VERSION 3.12)

file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")

This at least lets you avoid manually re-running CMake every time a file is added.

I was trying to connect Visual Studio 2013 to Visual Studio Team Services, and am behind a corporate proxy. I made VS use the default proxy settings (as specified in IE's connection settings) by adding:

<system.net> <defaultProxy useDefaultCredentials="true" enabled="true"> <proxy usesystemdefault="True" /> </defaultProxy> <settings> <ipv6 enabled="true"/> </settings> </system.net>

to ..\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe.config (running notepad as admin and opening the file from within there)

For CSS that are reused among the entire site I define them in the <head> section of the _Layout:

<head>
    <link href="@Url.Content("~/Styles/main.css")" rel="stylesheet" type="text/css" />
    @RenderSection("Styles", false)
</head>

and if I need some view specific styles I define the Styles section in each view:

@section Styles {
    <link href="@Url.Content("~/Styles/view_specific_style.css")" rel="stylesheet" type="text/css" />
}

Edit: It's useful to know that the second parameter in @RenderSection, false, means that the section is not required on a view that uses this master page, and the view engine will blissfully ignore the fact that there is no "Styles" section defined in your view. If true, the view won't render and an error will be thrown unless the "Styles" section has been defined.

You can align it like that:

print('{:>8} {:>8} {:>8}'.format(*words))

where > means "align to right" and 8 is the width for specific value.

And here is a proof:

>>> for line in [[1, 128, 1298039], [123388, 0, 2]]:
    print('{:>8} {:>8} {:>8}'.format(*line))


       1      128  1298039
  123388        0        2

Ps. *line means the line list will be unpacked, so .format(*line) works similarly to .format(line[0], line[1], line[2]) (assuming line is a list with only three elements).

There is lots of information about the Fibonacci Sequence on wikipedia and on wolfram. A lot more than you may need. Anyway it is a good thing to learn how to use these resources to find (quickly if possible) what you need.

Write Fib sequence formula to infinite

In math, it's given in a recursive form:

In programming, infinite doesn't exist. You can use a recursive form translating the math form directly in your language, for example in Python it becomes:

def F(n):
    if n == 0: return 0
    elif n == 1: return 1
    else: return F(n-1)+F(n-2)

Try it in your favourite language and see that this form requires a lot of time as n gets bigger. In fact, this is O(2ⁿ) in time.

Go on on the sites I linked to you and will see this (on wolfram):

This one is pretty easy to implement and very, very fast to compute, in Python:

from math import sqrt
def F(n):
    return ((1+sqrt(5))**n-(1-sqrt(5))**n)/(2**n*sqrt(5))

An other way to do it is following the definition (from wikipedia):

The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself, yielding the sequence 0, 1, 1, 2, 3, 5, 8, etc.

If your language supports iterators you may do something like:

def F():
    a,b = 0,1
    while True:
        yield a
        a, b = b, a + b

Display startNumber to endNumber only from Fib sequence.

Once you know how to generate Fibonacci Numbers you just have to cycle trough the numbers and check if they verify the given conditions.

Suppose now you wrote a f(n) that returns the n-th term of the Fibonacci Sequence (like the one with sqrt(5) )

In most languages you can do something like:

def SubFib(startNumber, endNumber):
    n = 0
    cur = f(n)
    while cur <= endNumber:
        if startNumber <= cur:
            print cur
        n += 1
        cur = f(n)

In python I'd use the iterator form and go for:

def SubFib(startNumber, endNumber):
    for cur in F():
        if cur > endNumber: return
        if cur >= startNumber:
            yield cur

for i in SubFib(10, 200):
    print i

My hint is to learn to read what you need. Project Euler (google for it) will train you to do so :P Good luck and have fun!

For Picrofo EDY

It depends, if you use the ShowDialog() as a way of showing your form and to close it you use the close button instead of this.Close(). The form will not be disposed or destroyed, it will only be hidden and changes can be made after is gone. In order to properly close it you will need the Dispose() or Close() method. In the other hand, if you use the Show() method and you close it, the form will be disposed and can not be modified after.

I had to register my buttonid as a postbacktrigger...

Unpopular opinion from 2020:

When it comes to ASP.NET apps I still prefer WebClient over HttpClient because:

1. The modern implementation comes with async/awaitable task-based methods
2. Has smaller memory footprint and 2x-5x faster (other answers already mention that)
3. It's suggested to "reuse a single instance of HttpClient for the lifetime of your application". But ASP.NET has no "lifetime of application", only lifetime of a request.

I was running into a similar error in pywikipediabot. The .decode method is a step in the right direction but for me it didn't work without adding 'ignore':

ignore_encoding = lambda s: s.decode('utf8', 'ignore')

Ignoring encoding errors can lead to data loss or produce incorrect output. But if you just want to get it done and the details aren't very important this can be a good way to move faster.

One way I know is to use (for instance) JavaScript to copy the value out of the password field before submitting the form.

The main problem with this is that the solution is tied to JavaScript.

Then again, if it can be tied to JavaScript you might as well hash the password on the client-side before sending a request to the server.

By dragging and dropping the dll onto 'regasm' you can register it. You can open two 'Window Explorer' windows. One will contain the dll you wish to register. The 2nd window will be the location of the 'regasm' application. Scroll down in both windows so that you have a view of both the dll and 'regasm'. It helps to reduce the size of the two windows so they are side-by-side. Be sure to drag the dll over the 'regasm' that is labeled 'application'. There are several 'regasm' files but you only want the application.

just like in C and C++, the boolean or operator is ||

if (ActionsLogWriter.Close || ErrorDumpWriter.Close == true)
{
    // Do stuff here
}

You could use ArraySegment<T>. It's very light-weight as it doesn't copy the array:

string[] a = { "one", "two", "three", "four", "five" };
var segment = new ArraySegment<string>( a, 1, 2 );

Based on this discussion, I built this config.json that works perfectly:

    "dialect": "mysql",

You can use git archive to download a tar ball for a given tag or commit id:

git archive --format=tar --remote=[hostname]:[path to repo] [tag name] > tagged_version.tar

You can also export a zip archive of a tag.

1. List tags:

   git tag
   
   0.0.1
   0.1.0
   

2. Export a tag:

   git archive -o /tmp/my-repo-0.1.0.zip --prefix=my-repo-0.1.0/ 0.1.0
   

3. Notes:

   • You do not need to specify the format. It will be picked up by the output file name.
   • Specifying the prefix will make your code export to a directory (if you include a trailing slash).

This might help

var link = document.createElementNS("http://www.w3.org/1999/xhtml", "a");
    link.href = 'http://www.google.com';
    link.target = '_blank';
    var event = new MouseEvent('click', {
        'view': window,
        'bubbles': false,
        'cancelable': true
    });
    link.dispatchEvent(event);

Instead, you simply JOIN to both tables, and in your SELECT clause, return data from the one that matches:

I suggest you to go through this link Conditional Joins in SQL Server and T-SQL Case Statement in a JOIN ON Clause

e.g.

    SELECT  *
FROM    sys.indexes i
        JOIN sys.partitions p
            ON i.index_id = p.index_id 
        JOIN sys.allocation_units a
            ON a.container_id =
            CASE
               WHEN a.type IN (1, 3)
                   THEN  p.hobt_id 
               WHEN a.type IN (2)
                   THEN p.partition_id
               END 

Edit: As per comments.

You can not specify the join condition as you are doing.. Check the query above that have no error. I have take out the common column up and the right column value will be evaluated on condition.

Have you tried using the replaceAll method to replace any occurence of \n or \r with the empty String?

rake tmp:cache:clear might be what you're looking for.

You can use pure Python to do it:

json.dumps(list) # '[1, 2, [3, 4]]'

The selected answer is correct for iOS 6 and below.

In iOS 7, sizeWithFont:constrainedToSize:lineBreakMode: has been deprecated. It is now recommended you use boundingRectWithSize:options:attributes:context:.

CGRect expectedLabelSize = [yourString boundingRectWithSize:sizeOfRect
                                                    options:<NSStringDrawingOptions>
                                                 attributes:@{
                                                    NSFontAttributeName: yourString.font
                                                    AnyOtherAttributes: valuesForAttributes
                                                 }
                                                    context:(NSStringDrawingContext *)];

Note that the return value is a CGRect not a CGSize. Hopefully that'll be of some assistance to people using it in iOS 7.

This has been tested on Chrome, firefox and Safari. (I'm on a mac, so if someone has the result on IE, tell me to add it)

Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices.

You haven't shown us the most important part : the mapping and initialization of the relationships between your entities (i.e. the part you have problems with). So I'll show you how it should look like.

If you make the relationships bidirectional, you should thus have

class User {
    @OneToMany(mappedBy = "user")
    private Set<UserService> userServices = new HashSet<UserService>();
}

class UserService {
    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "service_code")
    private Service service;

    @Column(name = "blocked")
    private boolean blocked;
}

class Service {
    @OneToMany(mappedBy = "service")
    private Set<UserService> userServices = new HashSet<UserService>();
}

If you don't put any cascade on your relationships, then you must persist/save all the entities. Although only the owning side of the relationship (here, the UserService side) must be initialized, it's also a good practice to make sure both sides are in coherence.

User user = new User();
Service service = new Service();
UserService userService = new UserService();

user.addUserService(userService);
userService.setUser(user);

service.addUserService(userService);
userService.setService(service);

session.save(user);
session.save(service);
session.save(userService);

cpp-netlib has functions

namespace boost {
  namespace network {
    namespace uri {    
      inline std::string decoded(const std::string &input);
      inline std::string encoded(const std::string &input);
    }
  }
}

they allow to encode and decode URL strings very easy.

You need just to reverse your date digit and change - with ,:

new Date(2012,01,26).getTime(); // 02 becomes 01 because getMonth() method returns the month (from 0 to 11)

In your case:

var myDate="26-02-2012";
myDate=myDate.split("-");
new Date(parseInt(myDate[2], 10), parseInt(myDate[1], 10) - 1 , parseInt(myDate[0]), 10).getTime();

P.S. UK locale does not matter here.

Another possibility for not displayed local image is unintentional indent of the image reference - spaces before ![alt text](file).

This makes it 'code block' instead of 'image inclusion'. Just remove the leading spaces.

This page provides great understanding about the constructor and destructor attribute implementation and the sections within within ELF that allow them to work. After digesting the information provided here, I compiled a bit of additional information and (borrowing the section example from Michael Ambrus above) created an example to illustrate the concepts and help my learning. Those results are provided below along with the example source.

As explained in this thread, the constructor and destructor attributes create entries in the .ctors and .dtors section of the object file. You can place references to functions in either section in one of three ways. (1) using either the section attribute; (2) constructor and destructor attributes or (3) with an inline-assembly call (as referenced the link in Ambrus' answer).

The use of constructor and destructor attributes allow you to additionally assign a priority to the constructor/destructor to control its order of execution before main() is called or after it returns. The lower the priority value given, the higher the execution priority (lower priorities execute before higher priorities before main() -- and subsequent to higher priorities after main() ). The priority values you give must be greater than100 as the compiler reserves priority values between 0-100 for implementation. Aconstructor or destructor specified with priority executes before a constructor or destructor specified without priority.

With the 'section' attribute or with inline-assembly, you can also place function references in the .init and .fini ELF code section that will execute before any constructor and after any destructor, respectively. Any functions called by the function reference placed in the .init section, will execute before the function reference itself (as usual).

I have tried to illustrate each of those in the example below:

#include <stdio.h>
#include <stdlib.h>

/*  test function utilizing attribute 'section' ".ctors"/".dtors"
    to create constuctors/destructors without assigned priority.
    (provided by Michael Ambrus in earlier answer)
*/

#define SECTION( S ) __attribute__ ((section ( S )))

void test (void) {
printf("\n\ttest() utilizing -- (.section .ctors/.dtors) w/o priority\n");
}

void (*funcptr1)(void) SECTION(".ctors") =test;
void (*funcptr2)(void) SECTION(".ctors") =test;
void (*funcptr3)(void) SECTION(".dtors") =test;

/*  functions constructX, destructX use attributes 'constructor' and
    'destructor' to create prioritized entries in the .ctors, .dtors
    ELF sections, respectively.

    NOTE: priorities 0-100 are reserved
*/
void construct1 () __attribute__ ((constructor (101)));
void construct2 () __attribute__ ((constructor (102)));
void destruct1 () __attribute__ ((destructor (101)));
void destruct2 () __attribute__ ((destructor (102)));

/*  init_some_function() - called by elf_init()
*/
int init_some_function () {
    printf ("\n  init_some_function() called by elf_init()\n");
    return 1;
}

*/

The example helped cement the constructor/destructor behavior, hopefully it will be useful to others as well.

Using label and checkbox input

Keeps the selected item opened and togglable.

.collapse{_x000D_
  cursor: pointer;_x000D_
  display: block;_x000D_
  background: #cdf;_x000D_
}_x000D_
.collapse + input{_x000D_
  display: none; /* hide the checkboxes */_x000D_
}_x000D_
.collapse + input + div{_x000D_
  display:none;_x000D_
}_x000D_
.collapse + input:checked + div{_x000D_
  display:block;_x000D_
}

<label class="collapse" for="_1">Collapse 1</label>_x000D_
<input id="_1" type="checkbox"> _x000D_
<div>Content 1</div>_x000D_
_x000D_
<label class="collapse" for="_2">Collapse 2</label>_x000D_
<input id="_2" type="checkbox">_x000D_
<div>Content 2</div>

Using label and named radio input

Similar to checkboxes, it just closes the already opened one.
Use name="c1" type="radio" on both inputs.

.collapse{_x000D_
  cursor: pointer;_x000D_
  display: block;_x000D_
  background: #cdf;_x000D_
}_x000D_
.collapse + input{_x000D_
  display: none; /* hide the checkboxes */_x000D_
}_x000D_
.collapse + input + div{_x000D_
  display:none;_x000D_
}_x000D_
.collapse + input:checked + div{_x000D_
  display:block;_x000D_
}

<label class="collapse" for="_1">Collapse 1</label>_x000D_
<input id="_1" type="radio" name="c1"> _x000D_
<div>Content 1</div>_x000D_
_x000D_
<label class="collapse" for="_2">Collapse 2</label>_x000D_
<input id="_2" type="radio" name="c1">_x000D_
<div>Content 2</div>

Using tabindex and :focus

Similar to radio inputs, additionally you can trigger the states using the Tab key.
Clicking outside of the accordion will close all opened items.

.collapse > a{_x000D_
  background: #cdf;_x000D_
  cursor: pointer;_x000D_
  display: block;_x000D_
}_x000D_
.collapse:focus{_x000D_
  outline: none;_x000D_
}_x000D_
.collapse > div{_x000D_
  display: none;_x000D_
}_x000D_
.collapse:focus div{_x000D_
  display: block; _x000D_
}

<div class="collapse" tabindex="1">_x000D_
  <a>Collapse 1</a>_x000D_
  <div>Content 1....</div>_x000D_
</div>_x000D_
_x000D_
<div class="collapse" tabindex="1">_x000D_
  <a>Collapse 2</a>_x000D_
  <div>Content 2....</div>_x000D_
</div>

Using :target

Similar to using radio input, you can additionally use Tab and ⏎ keys to operate

.collapse a{_x000D_
  display: block;_x000D_
  background: #cdf;_x000D_
}_x000D_
.collapse > div{_x000D_
  display:none;_x000D_
}_x000D_
.collapse > div:target{_x000D_
  display:block; _x000D_
}

<div class="collapse">_x000D_
  <a href="#targ_1">Collapse 1</a>_x000D_
  <div id="targ_1">Content 1....</div>_x000D_
</div>_x000D_
_x000D_
<div class="collapse">_x000D_
  <a href="#targ_2">Collapse 2</a>_x000D_
  <div id="targ_2">Content 2....</div>_x000D_
</div>

Using <detail> and <summary> tags (pure HTML)

You can use HTML5's detail and summary tags to solve this problem without any CSS styling or Javascript. Please note that these tags are not supported by Internet Explorer.

<details>_x000D_
  <summary>Collapse 1</summary>_x000D_
  <p>Content 1...</p>_x000D_
</details>_x000D_
<details>_x000D_
  <summary>Collapse 2</summary>_x000D_
  <p>Content 2...</p>_x000D_
</details>

Most answers are being a bit unclear in mentioning that C# will always run slower due to the cost of performing actions that in C++ are performed only once at compile time, this performance cost is also impacted due runtime dependencies (more things to load to be able to run), not to mention that C# programs will always have higher memory footprint, all resulting in performance being more closely related to the capability of hardware available. The same is true to other languages that are interpreted or depend on a VM.

After playing with it for a very long time, this is what I came up with:

    jQuery.fn.scrollTo = function (elem) {
        var b = $(elem);
        this.scrollTop(b.position().top + b.height() - this.height());
    };

and I call it like this

$("#basketListGridHolder").scrollTo('tr[data-uid="' + basketID + '"]');

Well these all answers are good but for a newbie(which is do first time) these are confusing. There are other htaccess files which is reside in controller but we have to edit or add the htaccess in main project folder.

This is your codeigniter folder, where file resides like application,system,assets,uploads etc.

Your_project_folder/
application/
assets/
cgi-bin/
system/
.htaccess---->(Edit this file if not exist than create it)
index.php

Change this file as written below:

<IfModule mod_rewrite.c>
  RewriteEngine On
  # !IMPORTANT! Set your RewriteBase here and don't forget trailing and leading
  #  slashes.
  # If your page resides at http://www.example.com/mypage/test1
  # then use RewriteBase /mypage/test1/
  # Otherwise /
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
  # If we don't have mod_rewrite installed, all 404's
  # can be sent to index.php, and everything works as normal.
  # Submitted by: Anand Pandey
  ErrorDocument 404 /index.php
</IfModule>

and yes of course you need to change two lines of code in the application/config/config.php

//find the below code   
$config['index_page'] = "index.php";
$config['uri_protocol'] ="AUTO" 
//replace with the below code
$config['index_page'] = "";
$config['uri_protocol'] = "REQUEST_URI";

I found out that this worked for me. First copy this code in the .htaccess file.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

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.

This one may be better and shorter:

function stringIncludes(a, b) {
    return a.indexOf(b) >= 0;
}

Most answers here will work fine if you have just two conditions in your if-else. For more which is I guess what you want, you'll be using arrays. Every names corresponding element in names array you'll have an element in the hasNames array with the exact same index. Then it's a matter of these four lines.

names = "true";
var names = ["true","false","1","2"];
var hasNames = ["Y","N","true","false"];
var intIndex = names.indexOf(name);
hasName = hasNames[intIndex ];

This method could also be implemented using Objects and properties as illustrated by Benjamin.

How about this:

SELECT DISTINCT ON (name) *
FROM messages
ORDER BY name, id DESC;

I had similar issue (on postgresql tough) and on a 1M records table. This solution takes 1.7s vs 44s produced by the one with LEFT JOIN. In my case I had to filter the corrispondant of your name field against NULL values, resulting in even better performances by 0.2 secs

First post :)

For the OP, kristof's solution will work, unless there are issues with massive data and transaction log balloon issues on big deletes. Also, even with tlog storage to spare, since deletes write to the tlog, the operation can take a VERY long time for tables with hundreds of millions of rows.

I use a series of cursors to truncate and reload large copies of one of our huge production databases frequently. The solution engineered accounts for multiple schemas, multiple foreign key columns, and best of all can be sproc'd out for use in SSIS.

It involves creation of three staging tables (real tables) to house the DROP, CREATE, and CHECK FK scripts, creation and insertion of those scripts into the tables, and then looping over the tables and executing them. The attached script is four parts: 1.) creation and storage of the scripts in the three staging (real) tables, 2.) execution of the drop FK scripts via a cursor one by one, 3.) Using sp_MSforeachtable to truncate all the tables in the database other than our three staging tables and 4.) execution of the create FK and check FK scripts at the end of your ETL SSIS package.

Run the script creation portion in an Execute SQL task in SSIS. Run the "execute Drop FK Scripts" portion in a second Execute SQL task. Put the truncation script in a third Execute SQL task, then perform whatever other ETL processes you need to do prior to attaching the CREATE and CHECK scripts in a final Execute SQL task (or two if desired) at the end of your control flow.

Storage of the scripts in real tables has proven invaluable when the re-application of the foreign keys fails as you can select * from sync_CreateFK, copy/paste into your query window, run them one at a time, and fix the data issues once you find ones that failed/are still failing to re-apply.

Do not re-run the script again if it fails without making sure that you re-apply all of the foreign keys/checks prior to doing so, or you will most likely lose some creation and check fk scripting as our staging tables are dropped and recreated prior to the creation of the scripts to execute.

Wrote the below function that allows me to quickly check to see if an index exists; works just like OBJECT_ID.

CREATE FUNCTION INDEX_OBJECT_ID (
    @tableName VARCHAR(128),
    @indexName VARCHAR(128)
    )
RETURNS INT
AS
BEGIN
    DECLARE @objectId INT

    SELECT @objectId = i.object_id
    FROM sys.indexes i
    WHERE i.object_id = OBJECT_ID(@tableName)
    AND i.name = @indexName

    RETURN @objectId
END
GO

EDIT: This just returns the OBJECT_ID of the table, but it will be NULL if the index doesn't exist. I suppose you could set this to return index_id, but that isn't super useful.

Using task scheduler, schedule a run of CMDKEY running under SYSTEM with the appropriate arguments of /add: /user: and /pass:

No need to install anything.

To expand a little more, there are two kinds of constructors: instance initializers (.ctor), type initializers (.cctor). Build the code below, and explore the IL code in ildasm.exe. You will notice that the static field 'b' will be initialized through .cctor() whereas the instance field will be initialized through .ctor()

internal sealed class CtorExplorer
{
   protected int a = 0;
   protected static int b = 0;
}

Even same issue I faced, in browser it was showing compiled code. I have made below changes in webpack config file and it is working fine now.

 devtool: '#inline-source-map',
 debug: true,

and in loaders I kept babel-loader as first option

loaders: [
  {
    loader: "babel-loader",
    include: [path.resolve(__dirname, "src")]
  },
  { test: /\.js$/, exclude: [/app\/lib/, /node_modules/], loader: 'ng-annotate!babel' },
  { test: /\.html$/, loader: 'raw' },
  {
    test: /\.(jpe?g|png|gif|svg)$/i,
    loaders: [
      'file?hash=sha512&digest=hex&name=[hash].[ext]',
      'image-webpack?bypassOnDebug&optimizationLevel=7&interlaced=false'
    ]
  },
  {test: /\.less$/, loader: "style!css!less"},
  { test: /\.styl$/, loader: 'style!css!stylus' },
  { test: /\.css$/, loader: 'style!css' }
]

You could also use the below, the iif avoids the case statement and only adds ellipses when required (only good in SQL Server 2012 and later) and the case statement is more ANSI compliant (but more verbose)

SELECT 
  col, LEN(col), 
  col2, LEN(col2), 
  col3, LEN(col3) FROM (
  SELECT 
    col, 
    LEFT(x.col, 15) + (IIF(len(x.col) > 15, '...', '')) AS col2, 
    LEFT(x.col, 15) + (CASE WHEN len(x.col) > 15 THEN '...' ELSE '' END) AS col3 
  from (
      select 'this is a long string. One that is longer than 15 characters' as col
      UNION 
      SELECT 'short string' AS col
      UNION 
      SELECT 'string==15 char' AS col
      UNION 
      SELECT NULL AS col
      UNION 
      SELECT '' AS col
) x
) y

SELECT *
FROM LogRequests
WHERE cast(dateX as date) between '2014-05-09' and '2014-05-10';

This will select all the data between the 2 dates

Use it in App Delegate: I am using storyboard

Vue.js uses vue-loader, a loader for WebPack which is set up to rewrite/convert paths at compile time, in order to allow you to not worry about static paths that would differ between deployments (local, dev, one hosting platform or the other), by allowing you to use relative local filesystem paths. It also adds other benefits like asset caching and versioning (you can probably see this by checking the actual src URL being generated).

So having a src that would normally be handled by vue-loader/WebPack set to a dynamic expression, evaluated at runtime, will circumvent this mechanism and the dynamic URL generated will be invalid in the context of the actual deployment (unless it's fully qualified, that's an exception).

If instead, you would use a require function call in the dynamic expression, vue-loader/WebPack will see it and apply the usual magic.

For example, this wouldn't work:

<img alt="Logo" :src="logo" />

computed: {
    logo() {
        return this.colorMode === 'dark'
               ? './assets/logo-dark.png'
               : './assets/logo-white.png';
    }
}

While this would work:

<img alt="Logo" :src="logo" />

computed: {
    logo() {
        return this.colorMode === 'dark'
               ? require('./assets/logo-dark.png')
               : require('./assets/logo-white.png');
    }
}

I just found out about this myself. Took me an hour but... you live, you learn, right?

You need to use ListBox.ItemContainerStyle.

ListBox.ItemTemplate specifies how the content of an item should be displayed. But WPF still wraps each item in a ListBoxItem control, which by default gets its Background set to the system highlight colour if it is selected. You can't stop WPF creating the ListBoxItem controls, but you can style them -- in your case, to set the Background to always be Transparent or Black or whatever -- and to do so, you use ItemContainerStyle.

juFo's answer shows one possible implementation, by "hijacking" the system background brush resource within the context of the item style; another, perhaps more idiomatic technique is to use a Setter for the Background property.

It can be done with simple commands in the following snippet.

Copies the whole file of any size. No size constraint!

Just use this. Tested And Working!!

#include<iostream>
#include<fstream>
using namespace std;
int main()
{
  ifstream infile;
  infile.open("source.pdf",ios::binary|ios::in);

  ofstream outfile;
  outfile.open("temppdf.pdf",ios::binary|ios::out);

  int buffer[2];
  while(infile.read((char *)&buffer,sizeof(buffer)))
  {
      outfile.write((char *)&buffer,sizeof(buffer));
  }

  infile.close();
  outfile.close();
  return 0;
}

Having a smaller buffer size would be helpful in copying tiny files. Even "char buffer[2]" would do the job.

Center in container

The code below does the same thing as centering in the Interface Builder.

override func viewDidLoad() {
    super.viewDidLoad()

    // set up the view
    let myView = UIView()
    myView.backgroundColor = UIColor.blue
    myView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(myView)

    // Add code for one of the constraint methods below
    // ...
}

Method 1: Anchor Style

myView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
myView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

Method 2: NSLayoutConstraint Style

NSLayoutConstraint(item: myView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true

Notes

• Anchor style is the preferred method over NSLayoutConstraint Style, however it is only available from iOS 9, so if you are supporting iOS 8 then you should still use NSLayoutConstraint Style.
• You will also need to add length and width constraints.
• My full answer is here.

On my case clearing buildpacks worked heroku buildpacks:clear

As you are reading the binary file, you need to unpack it into a integer, so use struct module for that

import struct
fin = open("hi.bmp", "rb")
firm = fin.read(2)  
file_size, = struct.unpack("i",fin.read(4))

I have a widget which does relatively frequent updates when the device is awake and I was seeing thousands of crashes in just a few days.

The issue trigger

I even noticed the issue even on my Pixel 3 XL when I wouldn't have thought the device to have much load at all. And any and all code paths were covered with startForeground(). But then I realized that in many cases my service gets the job done really quickly. I believe the trigger for my app was that the service was finishing before the system actually got around to showing a notification.

The workaround/solution

I was able to get rid of all crashes. What I did was to remove the call to stopSelf(). (I was thinking about delaying the stop until I was pretty sure the notification was shown, but I don't want the user to see the notification if it isn't necessary.) When the service has been idle for a minute or the system destroys it normally without throwing any exceptions.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    stopForeground(true);
} else {
    stopSelf();
}

Another option is replacing double quotes with single quotes if you don't mind whatever it is. But I don't mention this one:

<option value='"asd'>test</option>

I mention this one:

<option value="'asd">test</option>

In my case I used this solution.

Example: http://bootply.com/103783

One way to achieve this is using a position:fixed container for the background image and place it outside of the .jumbotron. Make the bg container the same height as the .jumbotron and center the background image:

background: url('/assets/example/...jpg') no-repeat center center;

CSS

.bg {
  background: url('/assets/example/bg_blueplane.jpg') no-repeat center center;
  position: fixed;
  width: 100%;
  height: 350px; /*same height as jumbotron */
  top:0;
  left:0;
  z-index: -1;
}

.jumbotron {
  margin-bottom: 0px;
  height: 350px;
  color: white;
  text-shadow: black 0.3em 0.3em 0.3em;
  background:transparent;
}

Then use jQuery to decrease the height of the .jumbtron as the window scrolls. Since the background image is centered in the DIV it will adjust accordingly -- creating a parallax affect.

JavaScript

var jumboHeight = $('.jumbotron').outerHeight();
function parallax(){
    var scrolled = $(window).scrollTop();
    $('.bg').css('height', (jumboHeight-scrolled) + 'px');
}

$(window).scroll(function(e){
    parallax();
});

Many algorithms will specify that duplicates are excluded. For example, the example algorithms in the MIT Algorithms book usually present examples without duplicates. It is fairly trivial to implement duplicates (either as a list at the node, or in one particular direction.)

Most (that I've seen) specify left children as <= and right children as >. Practically speaking, a BST which allows either of the right or left children to be equal to the root node, will require extra computational steps to finish a search where duplicate nodes are allowed.

It is best to utilize a list at the node to store duplicates, as inserting an '=' value to one side of a node requires rewriting the tree on that side to place the node as the child, or the node is placed as a grand-child, at some point below, which eliminates some of the search efficiency.

You have to remember, most of the classroom examples are simplified to portray and deliver the concept. They aren't worth squat in many real-world situations. But the statement, "every element has a key and no two elements have the same key", is not violated by the use of a list at the element node.

So go with what your data structures book said!

Edit:

Universal Definition of a Binary Search Tree involves storing and search for a key based on traversing a data structure in one of two directions. In the pragmatic sense, that means if the value is <>, you traverse the data structure in one of two 'directions'. So, in that sense, duplicate values don't make any sense at all.

This is different from BSP, or binary search partition, but not all that different. The algorithm to search has one of two directions for 'travel', or it is done (successfully or not.) So I apologize that my original answer didn't address the concept of a 'universal definition', as duplicates are really a distinct topic (something you deal with after a successful search, not as part of the binary search.)

This thread (dead now) contains really wonderful stuff. But I'm not able to do it right on this page using FF 3.5b99 + FireBug due to "Security Error".

Yipee!! I was able to select whole right hand sidebar with this code hope it helps you:

    var r = document.createRange();
    var w=document.getElementById("sidebar");  
    r.selectNodeContents(w);  
    var sel=window.getSelection(); 
    sel.removeAllRanges(); 
    sel.addRange(r); 

PS:- I was not able to use objects returned by jquery selectors like

   var w=$("div.welovestackoverflow",$("div.sidebar"));
   
   //this throws **security exception**

   r.selectNodeContents(w);

Use the DataContractJsonSerializer class: MSDN1, MSDN2.

My example: HERE.

It can also safely deserialize objects from a JSON string, unlike JavaScriptSerializer. But personally I still prefer Json.NET.

by XML:

 <EditText
        android:id="@+id/search_edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/search"
        android:imeOptions="actionSearch"
        android:inputType="text" />

By Java:

 editText.clearFocus();
    InputMethodManager in = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    in.hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);

I had to manage a scenario where the percentage of duplicates being provided in the new data records was very high, and so many thousands of database calls were being made to check for duplicates (so the CPU sent a lot of time at 100%). In the end I decided to keep the last 100,000 records cached in memory. This way I could check for duplicates against the cached records which was extremely fast when compared to a LINQ query against the SQL database, and then write any genuinely new records to the database (as well as add them to the data cache, which I also sorted and trimmed to keep its length manageable).

Note that the raw data was a CSV file that contained many individual records that had to be parsed. The records in each consecutive file (which came at a rate of about 1 every 5 minutes) overlapped considerably, hence the high percentage of duplicates.

In short, if you have timestamped raw data coming in, pretty much in order, then using a memory cache might help with the record duplication check.

You could use LINQ:

var checkedButton = container.Controls.OfType<RadioButton>()
                                      .FirstOrDefault(r => r.Checked);

Note that this requires that all of the radio buttons be directly in the same container (eg, Panel or Form), and that there is only one group in the container. If that is not the case, you could make List<RadioButton>s in your constructor for each group, then write list.FirstOrDefault(r => r.Checked).

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

For me it started working after selecting "Remove additional files at destination" in File publish options under settings on the publish dialog.

Just going to add a simple example to what everyone has explained,

json.load()

json.load can deserialize a file itself i.e. it accepts a file object, for example,

# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
  print(json.load(content))

will output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I use json.loads to open a file instead,

# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
  print(json.loads(content))

I would get this error:

TypeError: expected string or buffer

json.loads()

json.loads() deserialize string.

So in order to use json.loads I will have to pass the content of the file using read() function, for example,

using content.read() with json.loads() return content of the file,

with open("json_data.json", "r") as content:
  print(json.loads(content.read()))

Output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

That's because type of content.read() is string, i.e. <type 'str'>

If I use json.load() with content.read(), I will get error,

with open("json_data.json", "r") as content:
  print(json.load(content.read()))

Gives,

AttributeError: 'str' object has no attribute 'read'

So, now you know json.load deserialze file and json.loads deserialize a string.

Another example,

sys.stdin return file object, so if i do print(json.load(sys.stdin)), I will get actual json data,

cat json_data.json | ./test.py

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I want to use json.loads(), I would do print(json.loads(sys.stdin.read())) instead.

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

You could also try jARVEST.

It is based on a JRuby DSL over a pure-Java engine to spider-scrape-transform web sites.

Example:

Find all links inside a web page (wget and xpath are constructs of the jARVEST's language):

wget | xpath('//a/@href')

Inside a Java program:

Jarvest jarvest = new Jarvest();
  String[] results = jarvest.exec(
    "wget | xpath('//a/@href')", //robot! 
    "http://www.google.com" //inputs
  );
  for (String s : results){
    System.out.println(s);
  }

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

The quickest and easiest way to fix this is to do a find and replace on your date seperator, with the same separator. For example in this case Find "-" and Replace with "-", not sure why this works but you will find all dates are right-aligned as they should be after doing this.

I know this question is not about array of objects, but searchers do end up here.

so it's worth adding for future readers a proper ES6 way of merging and then removing duplicates

array of objects:

var arr1 = [ {a: 1}, {a: 2}, {a: 3} ];
var arr2 = [ {a: 1}, {a: 2}, {a: 4} ];

var arr3 = arr1.concat(arr2.filter( ({a}) => !arr1.find(f => f.a == a) ));

// [ {a: 1}, {a: 2}, {a: 3}, {a: 4} ]

See the Create a video slideshow from images – FFmpeg

If your video does not show the frames correctly If you encounter problems, such as the first image is skipped or only shows for one frame, then use the fps video filter instead of -r for the output framerate

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4

Alternatively the format video filter can be added to the filter chain to replace -pix_fmt yuv420p like "fps=25,format=yuv420p". The advantage of this method is that you can control which filter goes first

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf "fps=25,format=yuv420p" out.mp4

I tested below parameters, it worked for me

"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -vf "fps=25,format=yuv420p" e:\out.mp4

below parameters also worked but it always skips the first image

"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p e:\out.mp4

making a video from images placed in different folders

First, add image paths to imagepaths.txt like below.

# this is a comment details https://trac.ffmpeg.org/wiki/Concatenate

file 'E:\images\png\images__%3d.jpg'
file 'E:\images\jpg\images__%3d.jpg'

Sample usage as follows;

"h:\ffmpeg\ffmpeg.exe" -y -r 1/5 -f concat -safe 0 -i "E:\images\imagepaths.txt" -c:v libx264 -vf "fps=25,format=yuv420p" "e:\out.mp4"

-safe 0 parameter prevents Unsafe file name error

Changing your lists to numpy arrays will do the job!!

import matplotlib.pyplot as plt
from scipy import stats
import numpy as np 

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78]) # x is a numpy array now
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,0.478,0.335,0.365,0.424,0.390,0.585,0.511]) # y is a numpy array now
xerr = [0.01]*15
yerr = [0.001]*15

plt.rc('font', family='serif', size=13)
m, b = np.polyfit(x, y, 1)
plt.plot(x,y,'s',color='#0066FF')
plt.plot(x, m*x + b, 'r-') #BREAKS ON THIS LINE
plt.errorbar(x,y,xerr=xerr,yerr=0,linestyle="None",color='black')
plt.xlabel('$\Delta t$ $(s)$',fontsize=20)
plt.ylabel('$\Delta p$ $(hPa)$',fontsize=20)
plt.autoscale(enable=True, axis=u'both', tight=False)
plt.grid(False)
plt.xlim(0.2,1.2)
plt.ylim(0,0.8)
plt.show()

You have to use UPDATE instead of INSERT:

• UPDATE Syntax

For Example:

UPDATE table1 SET col_a='k1', col_b='foo' WHERE key_col='1';
UPDATE table1 SET col_a='k2', col_b='bar' WHERE key_col='2';

Here are two other software packages which can be used for DNS caching on Linux:

• dnsmasq
• bind

After configuring the software for DNS forwarding and caching, you then set the system's DNS resolver to 127.0.0.1 in /etc/resolv.conf.

If your system is using NetworkManager you can either try using the dns=dnsmasq option in /etc/NetworkManager/NetworkManager.conf or you can change your connection settings to Automatic (Address Only) and then use a script in the /etc/NetworkManager/dispatcher.d directory to get the DHCP nameserver, set it as the DNS forwarding server in your DNS cache software and then trigger a configuration reload.

Did you remember to include the closing brace in main?

#include <iostream>
#include "Attack.h"

using namespace std;

int main()
{
  Attack attackObj;
  attackObj.printShiz();
}

I notice this question gets quite a lot of views so I'll first address a question you didn't ask!

Regarding the title. To achieve a "Sql Union All with “distinct”" then simply replace UNION ALL with UNION. This has the effect of removing duplicates.

For your specific question, given the clarification "The first query should have "priority", so duplicates should be removed from bottom" you can use

SELECT col1,
       col2,
       MIN(grp) AS source_group
FROM   (SELECT 1 AS grp,
               col1,
               col2
        FROM   t1
        UNION ALL
        SELECT 2 AS grp,
               col1,
               col2
        FROM   t2) AS t
GROUP  BY col1,
          col2
ORDER  BY MIN(grp),
          col1  

Easy stuff:

this function will accept the target $hash and $replacements is also a hash containing newkey=>oldkey associations.

This function will preserve original order, but could be problematic for very large (like above 10k records) arrays regarding performance & memory.

function keyRename(array $hash, array $replacements) {
    $new=array();
    foreach($hash as $k=>$v)
    {
        if($ok=array_search($k,$replacements))
            $k=$ok;
        $new[$k]=$v;
    }
    return $new;    
}

this alternative function would do the same, with far better performance & memory usage, at the cost of loosing original order (which should not be a problem since it is hashtable!)

function keyRename(array $hash, array $replacements) {

    foreach($hash as $k=>$v)
        if($ok=array_search($k,$replacements))
        {
          $hash[$ok]=$v;
          unset($hash[$k]);
        }

    return $hash;       
}

EncodedParams variable is redefined as params variable will not work. You need to have same predefined call to variable, otherwise it looks possible with a little more work. Cheers! json is not used to its full capabilities in php there are better ways to call json which I don't recall at the moment.

This is one more option: go to Windows > Preference > Java > Editor > Content Assit. Look in "Auto Activation" zone, sure that "Enable auto activation" is checked and add more charactor (like "abcd....yz, default is ".") to auto show content assist menu as your typing.

I had a Third Party application (Fiddler) running to try and see the requests being sent. Closing this application fixed it for me

Installing framework 4.0 redistributable is also enough to create application pool. You can download it from here.

path is simply new in Django 2.0, which was only released a couple of weeks ago. Most tutorials won't have been updated for the new syntax.

It was certainly supposed to be a simpler way of doing things; I wouldn't say that URL is more powerful though, you should be able to express patterns in either format.

An important rule with respect to default parameter usage:
Default parameters should be specified at right most end, once you specify a default value parameter you cannot specify non default parameter again. ex:

int DoSomething(int x, int y = 10, int z) -----------> Not Allowed

int DoSomething(int x, int z, int y = 10) -----------> Allowed

Increment and decrement by 10.

I solved this problem by adding this line in my index.php:

$app['config']['view.compiled'] = "storage/framework/cache";

You can change the button color by applying a tint color to an UIAlertController.

On iOS 9, if the window tint color was set to a custom color, you have to apply the tint color right after presenting the alert. Otherwise the tint color will be reset to your custom window tint color.

// In your AppDelegate for example:
window?.tintColor = UIColor.redColor()

// Elsewhere in the App:
let alertVC = UIAlertController(title: "Title", message: "message", preferredStyle: .Alert)
alertVC.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: nil))
alertVC.addAction(UIAlertAction(title: "Ok", style: .Default, handler: nil))

// Works on iOS 8, but not on iOS 9
// On iOS 9 the button color will be red
alertVC.view.tintColor = UIColor.greenColor()

self.presentViewController(alert, animated: true, completion: nil)

// Necessary to apply tint on iOS 9
alertVC.view.tintColor = UIColor.greenColor()

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

You can check out this post on SuperUser.

Word starts page numbering over for each new section by default.

I do it slightly differently than the post above that goes through the ribbon menus, but in both methods you have to go through the document to each section's beginning.

My method:

• open up the footer (or header if that's where your page number is)
• drag-select the page number
• right-click on it
• hit Format Page Numbers
• click on the Continue from Previous Section radio button under Page numbering

I find this right-click method to be a little faster. Also, usually if I insert the page numbers first before I start making any new sections, this problem doesn't happen in the first place.

Use hashlib as hash() was designed to be used to:

quickly compare dictionary keys during a dictionary lookup

and therefore does not guarantee that it will be the same across Python implementations.

With hooks in React 16.8 onward, it's easy to do this with useEffect

I've created a CodeSandbox to demonstrate this.

useEffect(() => {
  // code to be run when state variables in
  // dependency array changes
}, [stateVariables, thatShould, triggerChange])

Basically, useEffect synchronises with state changes and this can be used to render the canvas

import React, { useState, useEffect, useRef } from "react";
import { Stage, Shape } from "@createjs/easeljs";
import "./styles.css";

export default function App() {
  const [rows, setRows] = useState(10);
  const [columns, setColumns] = useState(10);
  let stage = useRef()

  useEffect(() => {
    stage.current = new Stage("canvas");
    var rectangles = [];
    var rectangle;
    //Rows
    for (var x = 0; x < rows; x++) {
      // Columns
      for (var y = 0; y < columns; y++) {
        var color = "Green";
        rectangle = new Shape();
        rectangle.graphics.beginFill(color);
        rectangle.graphics.drawRect(0, 0, 32, 44);
        rectangle.x = y * 33;
        rectangle.y = x * 45;

        stage.current.addChild(rectangle);

        var id = rectangle.x + "_" + rectangle.y;
        rectangles[id] = rectangle;
      }
    }
    stage.current.update();
  }, [rows, columns]);

  return (
    <div>
      <div className="canvas-wrapper">
        <canvas id="canvas" width="400" height="300"></canvas>
        <p>Rows: {rows}</p>
        <p>Columns: {columns}</p>
      </div>
      <div className="array-form">
        <form>
          <label>Number of Rows</label>
          <select
            id="numRows"
            value={rows}
            onChange={(e) => setRows(e.target.value)}
          >
            {getOptions()}
          </select>
          <label>Number of Columns</label>
          <select
            id="numCols"
            value={columns}
            onChange={(e) => setColumns(e.target.value)}
          >
            {getOptions()}
          </select>
        </form>
      </div>
    </div>
  );
}

const getOptions = () => {
  const options = [1, 2, 5, 10, 12, 15, 20];
  return (
    <>
      {options.map((option) => (
        <option key={option} value={option}>
          {option}
        </option>
      ))}
    </>
  );
};

As you mentioned in a comment, you're using log4j. I discovered (inadvertently) a place where I had written

LOG.error(exc);

instead of the typical

LOG.error("Some informative message", e);

through laziness or perhaps just not thinking about it. The unfortunate part of this is that it doesn't behave as you expect. The logger API actually takes Object as the first argument, not a string - and then it calls toString() on the argument. So instead of getting the nice pretty stack trace, it just prints out the toString - which in the case of NPE is pretty useless.

Perhaps this is what you're experiencing?

First of all you can look here for a list of the various operations the individual iterator types need to support.

Next, when you have made your iterator class you need to either specialize std::iterator_traits for it and provide some necessary typedefs (like iterator_category or value_type) or alternatively derive it from std::iterator, which defines the needed typedefs for you and can therefore be used with the default std::iterator_traits.

disclaimer: I know some people don't like cplusplus.com that much, but they provide some really useful information on this.

Put into a script I like something like that:

#!/bin/bash
set -o xtrace # remove me after debug
TABLE=some_table_name
DB_NAME=prod_database

BASE_DIR=/var/backups/someDir
LOCATION="${BASE_DIR}/myApp_$(date +%Y%m%d_%H%M%S)"
FNAME="${LOCATION}_${DB_NAME}_${TABLE}.sql"

# Create backups directory if not exists
if [[ ! -e $BASE_DIR ]];then
       mkdir $BASE_DIR
       chown -R postgres:postgres $BASE_DIR
fi

sudo -H -u postgres pg_dump --column-inserts --data-only --table=$TABLE $DB_NAME > $FNAME
sudo gzip $FNAME

Bulk user creation with set_password

I you are creating several test users, bulk_create is much faster, but we can't use create_user with it.

set_password is another way to generate the hashed passwords:

def users_iterator():
    for i in range(nusers):
        is_superuser = (i == 0)
        user = User(
            first_name='First' + str(i),
            is_staff=is_superuser,
            is_superuser=is_superuser,
            last_name='Last' + str(i),
            username='user' + str(i),
        )
        user.set_password('asdfqwer')
        yield user

class Command(BaseCommand):
    def handle(self, **options):
        User.objects.bulk_create(iter(users_iterator()))

Question specific about password hashing: How to use Bcrypt to encrypt passwords in Django

Tested in Django 1.9.

How about creating a function to hijack the reject and return it ?

function createRejectablePromise(handler) {
  let _reject;

  const promise = new Promise((resolve, reject) => {
    _reject = reject;

    handler(resolve, reject);
  })

  promise.reject = _reject;
  return promise;
}

// Usage
const { reject } = createRejectablePromise((resolve) => {
  setTimeout(() => {
    console.log('resolved')
    resolve();
  }, 2000)

});

reject();

With a BorderLayout you need to use setPreferredSize instead of setSize

simply put in headers 'Content-Type': 'application/json' and the sent data in body JSON.stringify(string)

You need to rearrange your curly brackets. Your first statement is complete, so R interprets it as such and produces syntax errors on the other lines. Your code should look like:

if (dsnt<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else if (dst<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else {
  t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)       
} 

To put it more simply, if you have:

if(condition == TRUE) x <- TRUE
else x <- FALSE

Then R reads the first line and because it is complete, runs that in its entirety. When it gets to the next line, it goes "Else? Else what?" because it is a completely new statement. To have R interpret the else as part of the preceding if statement, you must have curly brackets to tell R that you aren't yet finished:

if(condition == TRUE) {x <- TRUE
 } else {x <- FALSE}

    mwebView.setDownloadListener(new DownloadListener()

    DownloadManager.Request request = new DownloadManager.Request(
            Uri.parse(url));


    request.setMimeType(mimeType);

We had this case where an .html file was seen as binary whenever we tried to make changes in it. Very uncool to not see diffs. To be honest, I didn't checked all the solutions here but what worked for us was the following:

1. Removed the file (actually moved it to my Desktop) and commited the git deletion. Git says Deleted file with mode 100644 (Regular) Binary file differs
2. Re-added the file (actually moved it from my Desktop back into the project). Git says New file with mode 100644 (Regular) 1 chunk, 135 insertions, 0 deletions The file is now added as a regular text file

From now on, any changes I made in the file is seen as a regular text diff. You could also squash these commits (1, 2, and 3 being the actual change you make) but I prefer to be able to see in the future what I did. Squashing 1 & 2 will show a binary change.

On MacOS:

1. Get the latest compiled SVN client binaries from here.
2. Install.
3. Add binaries to path (the last installation screen explains how).
4. Open terminal and run the following command on your project directory:

   svn upgrade

Since your config file is a normal text file, just read it using the open function:

file = open("abc.txt", 'r')
content = file.read()
paths = content.split("\n") #split it into lines
for path in paths:
    print path.split(" = ")[1]

This will print your paths. You can also store them using dictionaries or lists.

path_list = []
path_dict = {}
for path in paths:
    p = path.split(" = ")
    path_list.append(p)[1]
    path_dict[p[0]] = p[1]

More on reading/writing file here. Hope this helps!

If you were interested in the function not just the answer here is how it is done:

int ipToInt(int first, int second, 
    int third, int fourth)
{
    return Convert.ToInt32((first * Math.Pow(256, 3))
        + (second * Math.Pow(256, 2)) + (third * 256) + fourth);
}

with first through fourth being the segments of the IPv4 address.

This will cause Lint to ignore the missing translation error for ALL strings in the file, yet other string resource files can be verified if needed.

    tools:ignore="MissingTranslation">

I agree with some of the others' answers. The <head> and <header> tags have two unique and very unrelated functions. The <header> tag, if I'm not mistaken, was introduced in HTML5 and was created for increased accessibility, namely for screen readers. It's generally used to indicate the heading of your document and, in order to work appropriately and effectively, should be placed inside the <body> tag. The <head> tag, since it's origin, is used for SEO in that it constructs all of the necessary meta data and such. A valid HTML structure for your page with both tags included would be like something like this:

<!DOCTYPE html/>
<html lang="es">
    <head>
        <!--crazy meta stuff here-->
    </head>
    <body>
        <header>
            <!--Optional nav tag-->
            <nav>
            </nav>
        </header>
        <!--Body content-->
    </body>
</html>

Here is another way to drop all tables correctly, using sp_MSdropconstraints procedure. The shortest code I could think of:

exec sp_MSforeachtable "declare @name nvarchar(max); set @name = parsename('?', 1); exec sp_MSdropconstraints @name";
exec sp_MSforeachtable "drop table ?";

You can send the array to this function:

function utf8_converter($array){
    array_walk_recursive($array, function(&$item, $key){
        if(!mb_detect_encoding($item, 'utf-8', true)){
            $item = utf8_encode($item);
        }
    }); 
    return $array;
}

It works for me.

When you use the exec() function, it is as though you have a cmd terminal open and are typing commands straight to it.

Use single quotes like this $str = exec('start /B Path\to\batch.bat');
The /B means the bat will be executed in the background so the rest of the php will continue after running that line, as opposed to $str = exec('start /B /C command', $result); where command is executed and then result is stored for later use.

PS: It works for both Windows and Linux.
More details are here http://www.php.net/manual/en/function.exec.php :)

You can use foreignobject for more control and placing rich HTML content over rect or circle

    <svg width="250" height="250" xmlns="http://www.w3.org/2000/svg">_x000D_
        <rect x="0" y="0" width="250" height="250" fill="aquamarine" />_x000D_
        <foreignobject x="0" y="0" width="250" height="250">_x000D_
            <body xmlns="http://www.w3.org/1999/xhtml">_x000D_
                <div>Here is a long text that runs more than one line and works as a paragraph</div>_x000D_
                <br />_x000D_
                <div>This is <u>UNDER LINE</u> one</div>_x000D_
                <br />_x000D_
                <div>This is <b>BOLD</b> one</div>_x000D_
                <br />_x000D_
                <div>This is <i>Italic</i> one</div>_x000D_
            </body>_x000D_
        </foreignobject>_x000D_

Previous answers advise using the tarfile Python module for creating a .tar.gz file in Python. That's obviously a good and Python-style solution, but it has serious drawback in speed of the archiving. This question mentions that tarfile is approximately two times slower than the tar utility in Linux. According to my experience this estimation is pretty correct.

So for faster archiving you can use the tar command using subprocess module:

subprocess.call(['tar', '-czf', output_filename, file_to_archive])

You may come across this message/error, after installing epel-release. The quick fix is to update your SSL certificates:

yum -y upgrade ca-certificates

Chances are the above error may also occur while certificate update, if so, just disable the epel repo i.e. use the following command:

yum -y upgrade ca-certificates --disablerepo=epel 

Once the certificates will be updated, you'll be able to use yum normally, even the epel repo will work fine. In case you're getting this same error for a different repo, just put it's name against the --disablerepo=<repo-name> flag.

Note: use sudo if you're not the root user.

If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.

Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)

Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.

If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...

You are mixing the deprecated mysql extension with mysqli.

Try something like:

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

Use Array.GetUpperBound(0). Array.Length contains the number of items in the array, so reading Length -1 only works on the assumption that the array is zero based.

Let's answer your questions one by one.

1. Yes, you make a new object whenever this statement is executed, however, it goes "out of scope" when you exit the method and it is eligible for garbage collection.
2. Well this would be the same as #1, except that you've used a string type. A string type is immutable and you get a new object every time you make an assignment.
3. Yes the garbage collector collects the out of scope objects, unless you assign the object to a variable with a large scope such as class variable.
4. Yes.
5. The using statement only applies to objects that implement the IDisposable interface. If that is the case, by all means using is best for objects within a method's scope. Don't put Foo o at a larger scope unless you have a good reason to do so. It is best to limit the scope of any variable to the smallest scope that makes sense.

my mistake was making the target name "filename.c:" instead of just "filename:"

Some Special characters in the password create problem in proxy. Either escape them or avoid having special characters in password.

You want to join on condition 1 AND condition 2, so simply use the AND keyword as below

ON a.userid = b.sourceid AND a.listid = b.destinationid;

Paint.NET will create and edit PNGs with gusto. It's an excellent program in many respects. It's free as in beer and speech.

sudo /Applications/XAMPP/xamppfiles/bin/apachectl start

This fixed my issue AFTER ensuring my ports were all uniquely sorted out.

Here is a sample helper class which converts an Object and returns an Expando with all public properties of the given object.

    public static class dynamicHelper
        {
            public static ExpandoObject convertToExpando(object obj)
            {
                //Get Properties Using Reflections
                BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
                PropertyInfo[] properties = obj.GetType().GetProperties(flags);

                //Add Them to a new Expando
                ExpandoObject expando = new ExpandoObject();
                foreach (PropertyInfo property in properties)
                {
                    AddProperty(expando, property.Name, property.GetValue(obj));
                }

                return expando;
            }

            public static void AddProperty(ExpandoObject expando, string propertyName, object propertyValue)
            {
                //Take use of the IDictionary implementation
                var expandoDict = expando as IDictionary;
                if (expandoDict.ContainsKey(propertyName))
                    expandoDict[propertyName] = propertyValue;
                else
                    expandoDict.Add(propertyName, propertyValue);
            }
        }

Usage:

//Create Dynamic Object
dynamic expandoObj= dynamicHelper.convertToExpando(myObject);

//Add Custom Properties
dynamicHelper.AddProperty(expandoObj, "dynamicKey", "Some Value");

I've installed and use VB6 for legacy projects many times on Windows 7.

What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

Download here: http://www.microsoft.com/en-us/download/details.aspx?id=5721

Bonus: Also once you install it and realize that scrolling doesn't work, use the below: http://www.joebott.com/vb6scrollwheel.htm

If your are invoking fetch on a localhost server, use non-SSL unless you have a valid certificate for localhost. fetch will fail on an invalid or self signed certificate especially on localhost.

I will add that I had the same problem with a non-stored procedure query - just a plain select statement. To fix it, I declared a variable within the dataset SQL statement and set it equal to the SSRS parameter.

What an annoying workaround! Still, thank you all for getting me close to the answer!

another approach made available since this question was first asked is to use reactrb-express (see http://reactrb.org) This will let you script in ruby on the client side, replacing your html code with react components written in ruby.

Since you haven't initialized car yet so it has no existence in JVM(Java Virtual Machine) so you have to initialize it first.

For instance :

car = new String{"Porsche","Lamborghini"};

Now your code will run fine.

INPUT:

String car [];
car = new String{"Porsche","Lamborghini"};
System.out.println(car.length);

OUTPUT:

I know this has already been answered, but for anybody looking for a simple, no-frills implementation of a ViewPager indicator, I've implemented one that I've open sourced. For anyone finding Jake Wharton's version a bit complex for their needs, have a look at https://github.com/jarrodrobins/SimpleViewPagerIndicator.

Apache commons StringEscapeUtils.escapeEcmaScript(String) returns a string with unicode characters escaped using the \u notation.

"Art of Beer  " -> "Art of Beer \u1F3A8 \u1F37A"

I've solved it another way, if you like.

Here I used two arrays where searchChars containing which will be replaced and replaceChars containing desired characters.

var text = "your input string";_x000D_
var searchChars = ['Å','Ä','å','Ö','ö']; // add more charecter._x000D_
var replaceChars = ['A','A','a','O','o']; // exact same index to searchChars._x000D_
var index;_x000D_
for (var i = 0; i < text.length; i++) {_x000D_
  if( $.inArray(text[i], searchChars) >-1 ){ // $.inArray() is from jquery._x000D_
    index = searchChars.indexOf(text[i]);_x000D_
    text = text.slice(0, i) + replaceChars[index] + text.slice(i+1,text.length);_x000D_
  }_x000D_
}

A more modern version:

function arraysEqual(a, b) {
  a = Array.isArray(a) ? a : [];
  b = Array.isArray(b) ? b : [];
  return a.length === b.length && a.every((el, ix) => el === b[ix]);
}

Coercing non-array arguments to empty arrays stops a.every() from exploding.

If you just want to see if the arrays have the same set of elements then you can use Array.includes():

function arraysContainSame(a, b) {
  a = Array.isArray(a) ? a : [];
  b = Array.isArray(b) ? b : [];
  return a.length === b.length && a.every(el => b.includes(el));
}

if(view instanceof B)

This will return true if view is an instance of B or the subclass A (or any subclass of B for that matter).

The first thing you must know is that indexes are a way to avoid scanning the full table to obtain the result that you're looking for.

There are different kinds of indexes and they're implemented in the storage layer, so there's no standard between them and they also depend on the storage engine that you're using.

InnoDB and the B+Tree index

For InnoDB, the most common index type is the B+Tree based index, that stores the elements in a sorted order. Also, you don't have to access the real table to get the indexed values, which makes your query return way faster.

The "problem" about this index type is that you have to query for the leftmost value to use the index. So, if your index has two columns, say last_name and first_name, the order that you query these fields matters a lot.

So, given the following table:

CREATE TABLE person (
    last_name VARCHAR(50) NOT NULL,
    first_name VARCHAR(50) NOT NULL,
    INDEX (last_name, first_name)
);

This query would take advantage of the index:

SELECT last_name, first_name FROM person
WHERE last_name = "John" AND first_name LIKE "J%"

But the following one would not

SELECT last_name, first_name FROM person WHERE first_name = "Constantine"

Because you're querying the first_name column first and it's not the leftmost column in the index.

This last example is even worse:

SELECT last_name, first_name FROM person WHERE first_name LIKE "%Constantine"

Because now, you're comparing the rightmost part of the rightmost field in the index.

The hash index

This is a different index type that unfortunately, only the memory backend supports. It's lightning fast but only useful for full lookups, which means that you can't use it for operations like >, < or LIKE.

Since it only works for the memory backend, you probably won't use it very often. The main case I can think of right now is the one that you create a temporary table in the memory with a set of results from another select and perform a lot of other selects in this temporary table using hash indexes.

If you have a big VARCHAR field, you can "emulate" the use of a hash index when using a B-Tree, by creating another column and saving a hash of the big value on it. Let's say you're storing a url in a field and the values are quite big. You could also create an integer field called url_hash and use a hash function like CRC32 or any other hash function to hash the url when inserting it. And then, when you need to query for this value, you can do something like this:

SELECT url FROM url_table WHERE url_hash=CRC32("http://gnu.org");

The problem with the above example is that since the CRC32 function generates a quite small hash, you'll end up with a lot of collisions in the hashed values. If you need exact values, you can fix this problem by doing the following:

SELECT url FROM url_table 
WHERE url_hash=CRC32("http://gnu.org") AND url="http://gnu.org";

It's still worth to hash things even if the collision number is high cause you'll only perform the second comparison (the string one) against the repeated hashes.

Unfortunately, using this technique, you still need to hit the table to compare the url field.

Wrap up

Some facts that you may consider every time you want to talk about optimization:

1. Integer comparison is way faster than string comparison. It can be illustrated with the example about the emulation of the hash index in InnoDB.

2. Maybe, adding additional steps in a process makes it faster, not slower. It can be illustrated by the fact that you can optimize a SELECT by splitting it into two steps, making the first one store values in a newly created in-memory table, and then execute the heavier queries on this second table.

MySQL has other indexes too, but I think the B+Tree one is the most used ever and the hash one is a good thing to know, but you can find the other ones in the MySQL documentation.

I highly recommend you to read the "High Performance MySQL" book, the answer above was definitely based on its chapter about indexes.

If you want to find all occurences:

>>> re.findall('\(.*?\)',s)
[u"(date='2/xc2/xb2',time='/case/test.png')", u'(eee)']

>>> re.findall('\((.*?)\)',s)
[u"date='2/xc2/xb2',time='/case/test.png'", u'eee']

If you are developing an existing theme, it's possible that the theme has a custom list style.

So if you cant't change the list style using list-style: none; in ul or li tags, first check with !important, because maybe some other line of style is overwriting your style. If !important fixed it, you should find a more specific selector and clear out the !important.

li {
    list-style: none !important;
}

If it's not the case, then check the li:before. If it contains the content, then do:

li:before {
    display: none;
}

Although there's CSS defines a text-wrap property, it's not supported by any major browser, but maybe vastly supported white-space property solves your problem.

Typescript solution that clones the array instead of mutating existing one

export function swapItemsInArray<T>(items: T[], indexA: number, indexB: number): T[] {
  const itemA = items[indexA];

  const clone = [...items];

  clone[indexA] = clone[indexB];
  clone[indexB] = itemA;

  return clone;
}

@Creighton:

In Haskell there is a library function called product:

prouduct list = foldr 1 (*) list

or simply:

product = foldr 1 (*)

so the "idiomatic" factorial

fac n = foldr 1 (*)  [1..n]

would simply be

fac n = product [1..n]

I can't see any native .NET way to do it but if you want to get your hands dirty with the underlying Win32 controls...

You should be able to send it the CB_GETCOMBOBOXINFO message with a COMBOBOXINFO structure which will contain the internal edit control's handle. You can then send the edit control the EM_SETCUEBANNER message with a pointer to the string. (Note that this requires at least XP and visual styles to be enabled.

I've DONE it through this short and easy recipe:

Auto-sign commits on macOS (Globally and with different IDEs):

Get your signingkey in this way.

brew install gnupg gnupg2 pinentry-mac
git config --global user.signingkey <YOUR_SIGNING_KEY>
git config --global commit.gpgsign true
git config --global gpg.program gpg

Put the following in gpg.conf file (edit file with nano ~/.gnupg/gpg.conf command):

no-tty

Put the following in gpg-agent.conf file (edit file with nano ~/.gnupg/gpg-agent.conf command):

pinentry-program /usr/local/bin/pinentry-mac

Update:

You might need to execute killall gpg-agent command after editing the configurations file, gpg.conf, according to the comments. As the self-explanatory command says, this command will terminate the GPG (Gnu Privacy Guard) agent.

Quick answer: the FROM address must exactly match the account you are sending from, or you will get a error 5.7.1 Client does not have permissions to send as this sender.

My guess is that prevents email spoofing with your Office 365 account, otherwise you might be able to send as [email protected].

Another thing to try is in the authentication, fill in the third field with the domain, like

Dim smtpAuth = New System.Net.NetworkCredential(
    "TheDude", "hunter2password", "MicrosoftOffice365Domain.com")

If that doesn't work, double check that you can log into the account at: https://portal.microsoftonline.com

Yet another thing to note is your Antivirus solution may be blocking programmatic access to ports 25 and 587 as a anti-spamming solution. Norton and McAfee may silently block access to these ports. Only enabling Mail and Socket debugging will allow you to notice it (see below).

One last thing to note, the Send method is Asynchronous. If you call

Dispose

Detailed Answer: With Visual Studio (VB.NET or C# doesn't matter), I made a simple form with a button that created the Mail Message, similar to that above. Then I added this to the application.exe.config (in the bin/debug directory of my project). This enables the Output tab to have detailed debug info.

use the keyword break instead of return

To install GLIBC_2.14 or GLIBC_2.15, download package from /gnu/libc/ index at

https://ftp.gnu.org/gnu/libc/

Then follow instructions listed by Timo:

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz

2. cd glibc-2.14

3. mkdir build

4. cd build

5. ../configure --prefix=/opt/glibc-2.14

6. make

7. sudo make install

8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

I fixed this today...sort of. Although the archives still don't show up anywhere. But I got the Archive option back by going into Build Settings for the project and re-assigning my certs under "Code Signing Identity" for each build. They seemed to have gotten reset to something else when imported my 3.X project to 4.

I also used the instructions found here:

http://developer.apple.com/library/mac/#documentation/ToolsLanguages/Conceptual/Xcode4UserGuide/DistApps/DistApps.html#//apple_ref/doc/uid/TP40010215-CH11-DontLinkElementID_69

But I still can't get the actual archives to show up in Organizer (even though the files exist)

fastest solution:

If you have python 3.4.x, the solution is simply to install VC++ 2010 since it is used to compile itself into.

my python version is MSC v.1600 32 bit (intel)] on win32

worked fine on Windows8

1.Monolithic Kernel (Pure Monolithic) :all

• All Kernel Services From single component

  (-) addition/removal is not possible, less/Zero flexible

  (+) inter Component Communication is better

e.g. :- Traditional Unix

2.Micro Kernel :few

• few services(Memory management ,CPU management,IPC etc) from core kernel, other services(File management,I/O management. etc.) from different layers/component

• Split Approach [Some services is in privileged(kernel) mode and some are in Normal(user) mode]

  (+)flexible for changes/up-gradations

  (-)communication overhead

e.g.:- QNX etc.

3.Modular kernel(Modular Monolithic) :most

• Combination of Micro and Monolithic kernel

• Collection of Modules -- modules can be --> Static + Dynamic

• Drivers come in the form of Modules

One more way assume branch1 - is branch with committed changes branch2 - is desirable branch

git fetch && git checkout branch1
git log

select commit ids that you need to move

git fetch && git checkout branch2
git cherry-pick commit_id_first..commit_id_last
git push

Now revert unpushed commits from initial branch

git fetch && git checkout branch1
git reset --soft HEAD~1

Use os.environ[str(DEBUSSY)] for both reading and writing (http://docs.python.org/library/os.html#os.environ).

As for reading, you have to parse the number from the string yourself of course.

I'm using the following code in xml

android:adjustViewBounds="true"

Finally I got! Just to share, there are more config than just .env

This is .env

MAIL_DRIVER=smtp

MAIL_HOST=smtp.gmail.com

MAIL_PORT=587

[email protected]

MAIL_PASSWORD=********

MAIL_ENCRYPTION=tls

config/mail.php also need to input address & name for it to work.

'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'smtp.gmail.com'),
'port' => env('MAIL_PORT', 587),
'from' => ['address' => '[email protected]' , 'name' => 'YourName' ],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'sendmail' => '/usr/sbin/sendmail -bs',
'pretend' => false,

In my case, this was a test target that I removed all the pods from inside my podfile (because I added pods that I later realized I did not need in that target). None of the other solutions here worked for me.

1. Go to the Build Phases tab in the project settings for the target that's causing trouble.

2. Delete the section named "Check Pods Manifest" and "Copy Pods Resources"

3. Inside "Link Binary With Libraries" remove libPods-YourTarget.a

4. In your project settings in the Info tab expand "Configurations" and set the configuration for the target to None for both debug and release. (This will fix a couple of missing file warnings)

5. Delete your project's derived data (Window > Projects > Delete [next to your project) and restart Xcode. Build / run target.

Add border with radius in you class if its a block. because by default shadow will apply on block border, even if your image have rounded corner.

border-radius: 4px;

change its border radius according to your you image corner. Hope this help.

I've used JMeter. Besides testing the web server you can also test your database backend, messaging services and email servers.

Note: At the time I answered this question in 2010, there was no way to deserialize without some sort of type, this allowed you to deserialize without having go define the actual class and allowed an anonymous class to be used to do the deserialization.

You need to have some sort of type to deserialize to. You could do something along the lines of:

var product = new { Name = "", Price = 0 };
dynamic jsonResponse = JsonConvert.Deserialize(json, product.GetType());

My answer is based on a solution for .NET 4.0's build in JSON serializer. Link to deserialize to anonymous types is here:

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

You'll need to get the innerHTML of the option, and not its value.

Edit: You'll need to get the option element first and then use innerHTML.

Use this.text instead of this.selectedIndex.

The code that you have is correct. To get a variable from another class you need to create an instance of the class if the variable is not static, and just call the explicit method to get access to that variable. If you put get and set method like the above is the same of declaring that variable public.

Put the method setNum private and inside the getNum assign the value that you want, you will have "get" access to the variable in that case

Yes, ArrayList is an ordered collection and it maintains the insertion order.

Check the code below and run it:

public class ListExample {

    public static void main(String[] args) {
        List<String> myList = new ArrayList<String>();
        myList.add("one");
        myList.add("two");
        myList.add("three");
        myList.add("four");
        myList.add("five");
    
        System.out.println("Inserted in 'order': ");
        printList(myList);
        System.out.println("\n");
        System.out.println("Inserted out of 'order': ");

        // Clear the list
        myList.clear();
    
        myList.add("four");
        myList.add("five");
        myList.add("one");
        myList.add("two");
        myList.add("three");
    
        printList(myList);

Hi You can write data to bytes and then create a file in sdcard folder with whatever name and extension you want and then write the bytes to that file. This will save bitmap to sdcard.

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

//you can create a new file name "test.jpg" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
                        + File.separator + "test.jpg");
f.createNewFile();
//write the bytes in file
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());

// remember close de FileOutput
fo.close();

In general with this issue, first check that you're editing the file you think you are! I had this problem when I was editing a transpiled JavaScript file instead of the source file (the transpiled version wasn't under source control).

I've spent more time solving this error that I care to admit.

The order of authentication configuration in pg_hba.conf is relevant in your case I think. The default configuration file includes several lines in a vanilla install. These defaults can match the conditions of your authentication attempts resulting in a failure to authenticate. It fails regardless of additional configuration added at the end of the .conf file.

To check which line of configuration is use make sure to look at the default log file for messages. You might see something like this

LOG:  could not connect to Ident server at address "127.0.0.1", port 113: Connection refused
FATAL:  Ident authentication failed for user "acme" 
DETAIL:  Connection matched pg_hba.conf line 82: "host     all             all             127.0.0.1/32            ident"

It turns out this default line is causing the rejection.

host    all             all             127.0.0.1/32            ident

try commenting it out.

CSV Files with Custom Delimiters

By default, a comma is used as a delimiter in a CSV file. However, some CSV files can use delimiters other than a comma. Few popular ones are | and \t.

import csv
data_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter='|')
    writer.writerows(data_list)

output:

SN|Name|Contribution
1|Linus Torvalds|Linux Kernel
2|Tim Berners-Lee|World Wide Web
3|Guido van Rossum|Python Programming

Write CSV files with quotes

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC, delimiter=';')
    writer.writerows(row_list) 

output:

"SN";"Name";"Contribution"
1;"Linus Torvalds";"Linux Kernel"
2;"Tim Berners-Lee";"World Wide Web"
3;"Guido van Rossum";"Python Programming"

As you can see, we have passed csv.QUOTE_NONNUMERIC to the quoting parameter. It is a constant defined by the csv module.

csv.QUOTE_NONNUMERIC specifies the writer object that quotes should be added around the non-numeric entries.

There are 3 other predefined constants you can pass to the quoting parameter:

• csv.QUOTE_ALL - Specifies the writer object to write CSV file with quotes around all the entries.
• csv.QUOTE_MINIMAL - Specifies the writer object to only quote those fields which contain special characters (delimiter, quotechar or any characters in lineterminator)
• csv.QUOTE_NONE - Specifies the writer object that none of the entries should be quoted. It is the default value.

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC,
                        delimiter=';', quotechar='*')
    writer.writerows(row_list)

output:

*SN*;*Name*;*Contribution*
1;*Linus Torvalds*;*Linux Kernel*
2;*Tim Berners-Lee*;*World Wide Web*
3;*Guido van Rossum*;*Python Programming*

Here, we can see that quotechar='*' parameter instructs the writer object to use * as quote for all non-numeric values.

If you are using JSP 2.0 and above It will come with the EL support: so that you can write in plain english and use and with empty operators to write your test:

<c:if test="${(empty object_1.attribute_A) and (empty object_2.attribute_B)}">

In C++11, use std::to_string if you can accept the default format (%f).

storedCorrect[count]= "(" + std::to_string(c1) + ", " + std::to_string(c2) + ")";

You just subindex it with [:5] indicating that you want (up to) the first 5 elements.

>>> [1,2,3,4,5,6,7,8][:5]
[1, 2, 3, 4, 5]
>>> [1,2,3][:5]
[1, 2, 3]
>>> x = [6,7,8,9,10,11,12]
>>> x[:5]
[6, 7, 8, 9, 10]

Also, putting the colon on the right of the number means count from the nth element onwards -- don't forget that lists are 0-based!

>>> x[5:]
[11, 12]

You can turn autocommit ON by setting implicit_transactions OFF:

SET IMPLICIT_TRANSACTIONS OFF

When the setting is ON, it returns to implicit transaction mode. In implicit transaction mode, every change you make starts a transactions which you have to commit manually.

Maybe an example is clearer. This will write a change to the database:

SET IMPLICIT_TRANSACTIONS ON
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
COMMIT TRANSACTION

This will not write a change to the database:

SET IMPLICIT_TRANSACTIONS ON
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
ROLLBACK TRANSACTION

The following example will update a row, and then complain that there's no transaction to commit:

SET IMPLICIT_TRANSACTIONS OFF
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
ROLLBACK TRANSACTION

Like Mitch Wheat said, autocommit is the default for Sql Server 2000 and up.

Try this:

function _base64ToArrayBuffer(base64) {
    var binary_string = window.atob(base64);
    var len = binary_string.length;
    var bytes = new Uint8Array(len);
    for (var i = 0; i < len; i++) {
        bytes[i] = binary_string.charCodeAt(i);
    }
    return bytes.buffer;
}

Zoom is not included in the CSS specification, but it is supported in IE, Safari 4, Chrome (and you can get a somewhat similar effect in Firefox with -moz-transform: scale(x) since 3.5). See here.

So, all browsers

 zoom: 2;
 zoom: 200%;

will zoom your object in by 2, so it's like doubling the size. Which means if you have

a:hover {
   zoom: 2;
}

On hover, the <a> tag will zoom by 200%.

Like I say, in FireFox 3.5+ use -moz-transform: scale(x), it does much the same thing.

Edit: In response to the comment from thirtydot, I will say that scale() is not a complete replacement. It does not expand in line like zoom does, rather it will expand out of the box and over content, not forcing other content out of the way. See this in action here. Furthermore, it seems that zoom is not supported in Opera.

This post gives a useful insight into ways to work around incompatibilities with scale and workarounds for it using jQuery.

you can do it like this

$.when(funtion1()).then(function(){
    funtion2();
})

The quintessential example of this is an array of pointers to structs or objects (that are mutable).

A shallow copy copies the array and maintains references to the original objects.

A deep copy will copy (clone) the objects too so they bear no relation to the original. Implicit in this is that the object themselves are deep copied. This is where it gets hard because there's no real way to know if something was deep copied or not.

The copy constructor is used to initilize the new object with the previously created object of the same class. By default compiler wrote a shallow copy. Shallow copy works fine when dynamic memory allocation is not involved because when dynamic memory allocation is involved then both objects will points towards the same memory location in a heap, Therefore to remove this problem we wrote deep copy so both objects have their own copy of attributes in a memory.

In order to read the details with complete examples and explanations you could see the article Constructors and destructors.

The default copy constructor is shallow. You can make your own copy constructors deep or shallow, as appropriate. See C++ Notes: OOP: Copy Constructors.

Here's a version that works recursively (using *) on an arbitrary number of objects:

echo '{"A": {"a": 1}}' '{"A": {"b": 2}}' '{"B": 3}' |\
  jq --slurp 'reduce .[] as $item ({}; . * $item)'

{
  "A": {
    "a": 1,
    "b": 2
  },
  "B": 3
}

For styling each directional arrows(left, right,top and bottom), we have to select each arrow using CSS attribute selector and then style them individually.

Trick: Top arrow must have border color only on top side and transparent on other 3 sides. Other directional arrows also need to be styled this way.

Here is the simple CSS,

.tooltip-inner { background-color:#8447cf;}

[data-placement="top"] + .tooltip > .tooltip-arrow { border-top-color: #8447cf;}

[data-placement="right"] + .tooltip > .tooltip-arrow { border-right-color: #8447cf;}

[data-placement="bottom"] + .tooltip > .tooltip-arrow {border-bottom-color: #8447cf;}

[data-placement="left"] + .tooltip > .tooltip-arrow {border-left-color: #8447cf; }

shutil.rmtree() for most cases. But it doesn't work for in Windows for readonly files. For windows import win32api and win32con modules from PyWin32.

def rmtree(dirname):
    retry = True
    while retry:
        retry = False
        try:
            shutil.rmtree(dirname)
        except exceptions.WindowsError, e:
            if e.winerror == 5: # No write permission
                win32api.SetFileAttributes(dirname, win32con.FILE_ATTRIBUTE_NORMAL)
                retry = True

If you are catching an exception type, you do not need to throw it, unless you are going to rethrow it. In the example you post, the developer should have done one or another, not both.

Typically, if you are not going to do anything with the exception, you should not catch it.

The most dangerous thing you can do is catch an exception and not do anything with it.

A good discussion of when it is appropriate to throw exceptions is here
