Vadim Shender response is great. You can also use a simpler decorator like below:

import datetime
def calc_timing(original_function):                            
    def new_function(*args,**kwargs):                        
        start = datetime.datetime.now()                     
        x = original_function(*args,**kwargs)                
        elapsed = datetime.datetime.now()                      
        print("Elapsed Time = {0}".format(elapsed-start))     
        return x                                             
    return new_function()  

@calc_timing
def a_func(*variables):
    print("do something big!")

I tried almost all answers and nothing fix my error, so I just reinstall python (in my case I have version 2.7.9 and I install 2.7.15) and the error finally fixed. No need to uninstall python first, the installer do it for you.

To give a little more flexibility I would add the next function to my repository:

public function findByNot($field, $value)
{
    $qb = $this->createQueryBuilder('a');
    $qb->where($qb->expr()->not($qb->expr()->eq('a.'.$field, '?1')));
    $qb->setParameter(1, $value);

    return $qb->getQuery()
        ->getResult();
}

Then, I could call it in my controller like this:

$this->getDoctrine()->getRepository('MyBundle:Image')->findByNot('id', 1);

Just a brief note - I'm using a modified version of plain.bst sitting in the directory with my Latex files; it turns out having sorting by order of appearance is a relatively easy change; just find the piece of code:

...
ITERATE {presort}

SORT
...

... and comment it - I turned it to:

...
%% % avoid sort:
%% ITERATE {presort}
%%
%% SORT
...

... and then, after running bibtex, pdflatex, pdflatex - the citations will be sorted by order of appearance (that is, they will be unsorted :) ).

Cheers!

EDIT: just realized that what I wrote is actually in the comment by @ChrisN: "can you edit it to remove the SORT command" ;)

I'd do something like this:

<?php

/**
 * array_map_kv()
 *   An array mapping function to map with both keys and values.
 *
 * @param $callback callable
 *   A callback function($key, $value) for mapping values.
 * @param $array array
 *   An array for mapping.
 */
function array_map_kv(callable $callback, array $array) {
  return array_map(
    function ($key) use ($callback, $array) {
      return $callback($key, $array[$key]); // $callback($key, $value)
    },
    array_keys($array)
  );
}

// use it
var_dump(array_map_kv(function ($key, $value) {
  return "{$key} loves {$value}";
}, array(
  "first_key" => "first_value",
  "second_key" => "second_value",
)));

?>

Results:

array(2) {
  [0]=>
  string(27) "first_key loves first_value"
  [1]=>
  string(29) "second_key loves second_value"
}

No. Pylint doesn't currently let you discriminate between doc-string warnings.

However, you can use Flake8 for all Python code checking along with the doc-string extension to ignore this warning.

Install the doc-string extension with pip (internally, it uses pydocstyle).

pip install flake8_docstrings

You can then just use the --ignore D100 switch. For example, flake8 file.py --ignore D100

Since you've already received help on the query, I'll take a poke at your syntax question:

The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join and on clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.

Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:

select
 count(*)
from Table1 as t1
join Table2 as t2
    join Table3 as t3
    on t2.Key = t3.Key                   -- join #1
    and t2.Key2 = t3.Key2 
on t1.DifferentKey = t3.DifferentKey     -- join #2  

This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:

select
 count(*)
from Table1 as t1
    join Table3 as t3
        join Table2 as t2
        on t2.Key = t3.Key                   -- join #1
        and t2.Key2 = t3.Key2   
    on t1.DifferentKey = t3.DifferentKey     -- join #2

Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.

Arrays are special objects in java, they have a simple attribute named length which is final.

There is no "class definition" of an array (you can't find it in any .class file), they're a part of the language itself.

10.7. Array Members

The members of an array type are all of the following:

• The public final field length, which contains the number of components of the array. length may be positive or zero.

• The public method clone, which overrides the method of the same name in class Object and throws no checked exceptions. The return type of the clone method of an array type T[] is T[].

  A clone of a multidimensional array is shallow, which is to say that it creates only a single new array. Subarrays are shared.

• All the members inherited from class Object; the only method of Object that is not inherited is its clone method.

Resources:

• JLS - Arrays

1. move the code to a new branch - git branch -b tmp_branchyouwantmergedin
2. change to the branch you want to merge to - git checkout mycoolbranch
3. reset the branch you want to merge to - git branch reset --hard HEAD
4. merge the tmp branch into the desired branch - git branch merge tmp_branchyouwantmergedin
5. push to origin

Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global, nonlocal, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.

Here are some examples regarding global:-

>>> global_var = 5
>>> def fn():
...     print(global_var)
... 
>>> fn()
5
>>> def fn_2():
...     global_var += 2
...     print(global_var)
... 
>>> fn_2()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
...     global global_var
...     global_var += 2
...     print(global_var)
... 
>>> fn_3()
7

The same patterns can be applied to nonlocal variables too, but this keyword is only available to the latter Python versions.

In case you're wondering, nonlocal is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def within a def, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...

Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner defs using the same variable names as the outer ones, which just should just be avoided to be honest.

You can pass the variable to the Makefile like below:

run:
    @echo ./prog $$FOO

Usage:

$ make run FOO="the dog kicked the cat"
./prog the dog kicked the cat

or:

$ FOO="the dog kicked the cat" make run
./prog the dog kicked the cat

Alternatively use the solution provided by Beta:

run:
    @echo ./prog $(filter-out $@,$(MAKECMDGOALS))
%:
    @:

%: - rule which match any task name; @: - empty recipe = do nothing

Usage:

$ make run the dog kicked the cat
./prog the dog kicked the cat

/* eslint-disable */

//suppress all warnings between comments
alert('foo');

/* eslint-enable */

This will disable all eslint rules within the block.

You can set AWS_REGION environment.

assert(process.env.AWS_REGION, 'Missing AWS_REGION env (eg. ap-northeast-1)');
const aws = require('aws-sdk');
const lambda = new aws.Lambda();

Eclipse freezing at startup - before loading workspace very good answer on this post. repeating the answer that worked for me

In your workspace directory perform the following steps:

cd .metadata/.plugins

mv org.eclipse.core.resources org.eclipse.core.resources.bak

Start eclipse. (It should show an error message or an empty workspace because no project is found.)

Close all open editors tabs.

Exit eclipse.

rm -rf org.eclipse.core.resources (Delete the newly created directory.)

mv org.eclipse.core.resources.bak/ org.eclipse.core.resources (Restore the original directory.)

Start eclipse and start working. :-)

simply press Alt+F5 after updating your pom.xml. This will build your project again and download all jar files

I used the data_connection_checker package to check the internet access even if the connection available by wifi or mobile, it works well: here is the code to check the connection:

bool result = await DataConnectionChecker().hasConnection;
if(result == true) {
   print('YAY! Free cute dog pics!');
} else {
   print('No internet :( Reason:');
   print(DataConnectionChecker().lastTryResults);
}

head over the package if you want more information. Data Connection Checker Package

Two ways that can be works

1: Uninstall app from mobile device manually

2: Open command prompt , trace path of adband execute following command

adb uninstall your_package_name

Context is stored at the application level scope where as request is stored at page level i.e to say

Web Container brings up the applications one by one and run them inside its JVM. It stores a singleton object in its jvm where it registers anyobject that is put inside it.This singleton is shared across all applications running inside it as it is stored inside the JVM of the container itself.

However for requests, the container creates a request object that is filled with data from request and is passed along from one thread to the other (each thread is a new request that is coming to the server), also request is passed to the threads of same application.

The key distinction is repeating a captured group instead of capturing a repeated group.

As you have already found out, the difference is that repeating a captured group captures only the last iteration. Capturing a repeated group captures all iterations.

In PCRE (PHP):

((?:\w+)+),?

Match 1, Group 1.    0-5      HELLO
Match 2, Group 1.    6-11     THERE
Match 3, Group 1.    12-20    BRUTALLY
Match 4, Group 1.    21-26    CRUEL
Match 5, Group 1.    27-32    WORLD

Since all captures are in Group 1, you only need $1 for substitution.

I used the following general form of this regular expression:

((?:{{RE}})+)

Example at regex101

if (filter_section.getVisibility() == View.GONE) {
    filter_section.animate()
            .translationY(filter_section.getHeight()).alpha(1.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationStart(Animator animation) {
                    super.onAnimationStart(animation);
                    filter_section.setVisibility(View.VISIBLE);
                    filter_section.setAlpha(0.0f);
                }
            });
} else {
    filter_section.animate()
            .translationY(0).alpha(0.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    super.onAnimationEnd(animation);
                    filter_section.setVisibility(View.GONE);
                }
            });
}

We can use enum type for this.We don't require a library. For example

           enum {false,true};

the value for false will be 0 and the value for true will be 1.

Somehow easy install doesn't work on my old mac (10.8). This solve my problem.

wget https://bootstrap.pypa.io/get-pip.py

If you do not have wget, just open in browser https://bootstrap.pypa.io/get-pip.py then save as get-pip.py

Query Builder:

DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();

Eloquent:

SomeModel::select(..)->whereNotIn('book_price', [100,200])->get();

I had the same problem with bootstrap 3 and the modal-body div's height not wanting to be greater than 442px. This was all the css needed to fix it in my case:

.modal-body {
    overflow-y: auto;
}

You should create a variable of the type SelectionneNonSelectionne.

struct SelectionneNonSelectionne var;

After that pass that variable to the function like

characterSelection(screen, var);

The error is caused since you are passing the type name SelectionneNonSelectionne

As far as I can see, you just added heredoc by mistake

You can create multiple workspaces in Eclipse. You have to just specify the path of the workspace during Eclipse startup. You can even switch workspaces via File?Switch workspace.

You can then import project to your workspace, copy paste project to your new workspace folder, then

File?Import?Existing project in to workspace?select project.

I've found that in the majority of cases doing block clauses on one line is a bad idea.

It will, again as a generality, reduce the quality of the form of the code. High quality code form is a key language feature for python.

In some cases python will offer ways todo things on one line that are definitely more pythonic. Things such as what Nick D mentioned with the list comprehension:

newlist = [splitColon.split(a) for a in someList]

although unless you need a reusable list specifically you may want to consider using a generator instead

listgen = (splitColon.split(a) for a in someList)

note the biggest difference between the two is that you can't reiterate over a generator, but it is more efficient to use.

There is also a built in ternary operator in modern versions of python that allow you to do things like

string_to_print = "yes!" if "exam" in "example" else ""
print string_to_print

or

iterator = max_value if iterator > max_value else iterator

Some people may find these more readable and usable than the similar if (condition): block.

When it comes down to it, it's about code style and what's the standard with the team you're working on. That's the most important, but in general, i'd advise against one line blocks as the form of the code in python is so very important.

Enough is said already on the topic, however to keep it simple, here's my take.

Sorted dictionary should be used when-

• More inserts and delete operations are required.
• Data in un-ordered.
• Key access is enough and index access is not required.
• Memory is not a bottleneck.

On the other side, Sorted List should be used when-

• More lookups and less inserts and delete operations are required.
• Data is already sorted (if not all, most).
• Index access is required.
• Memory is an overhead.

Hope this helps!!

If possible I would suggest creating the Path directly from the path elements:

Path path = Paths.get("C:", "dir1", "dir2", "dir3");
// if needed
String textPath = path.toString(); // "C:\\dir1\\dir2\\dir3"

"??".encode('utf-8')

encode converts a unicode object to a string object. But here you have invoked it on a string object (because you don't have the u). So python has to convert the string to a unicode object first. So it does the equivalent of

"??".decode().encode('utf-8')

But the decode fails because the string isn't valid ascii. That's why you get a complaint about not being able to decode.

conda doesn't support this directly because it installs from binaries, whereas git install would be from source. conda build does support recipes that are built from git. On the other hand, if all you want to do is keep up-to-date with the latest and greatest of a package, using pip inside of Anaconda is just fine, or alternately, use setup.py develop against a git clone.

I also couldn't find my git repository. I am using Windows 8 and created my repository (by mistake) under C:\Program Files (x86)\Git. I could see the repository folder in bash but not in cmd or Windows Explorer.

You can manually set this using Laravel, just remember to add 'created_at' to your $fillable array:

protected $fillable = ['name', 'created_at']; 

Here is one way to do this using css

HTML

<div class="imageWrapper">

    <a href="http://google.com" class="cornerLink">Link</a>
</div>?

CSS

.imageWrapper {
    position: relative;
    width: 300px;
    height: 300px;
}
.imageWrapper img {
    display: block;
}
.imageWrapper .cornerLink {
    opacity: 0;
    position: absolute;
    bottom: 0px;
    left: 0px;
    right: 0px;
    padding: 2px 0px;
    color: #ffffff;
    background: #000000;
    text-decoration: none;
    text-align: center;
    -webkit-transition: opacity 500ms;
    -moz-transition: opacity 500ms;
    -o-transition: opacity 500ms;
    transition: opacity 500ms;

}
.imageWrapper:hover .cornerLink {
    opacity: 0.8;
}

( I'm simplifying this a little bit as all but cmp return a value that is both an empty string, and a numerically zero value instead of 0, and a value that is both the string '1' and the numeric value 1. These are the same values you will always get from boolean operators in Perl. You should really only be using the return values for boolean or numeric operations, in which case the difference doesn't really matter. )

This is probably the easiest way, not the prettiest though:

SELECT *,
    (SELECT Count(*) FROM eventsTable WHERE columnName = 'Business') as RowCount
    FROM eventsTable
    WHERE columnName = 'Business'

This will also work without having to use a group by

SELECT *, COUNT(*) OVER () as RowCount
    FROM eventsTables
    WHERE columnName = 'Business'

I try Easy Way to resolve it, share it with you :

let counter = 0;
            arr.forEach(async (item, index) => {
                await request.query(item, (err, recordset) => {
                    if (err) console.log(err);

                    //do Somthings

1. I added $scope.selectedItem that gets you past your first problem (defaulting the image)
2. I added $scope.setSelectedItem and called it in ng-click. Your final requirements may be different, but using a directive to bind click and change src was overkill, since most of it can be handled with template
3. Notice use of ngSrc to avoid errant server calls on initial load
4. You'll need to adjust some styles to get the image positioned right in the div. If you really need to use background-image, then you'll need a directive like ngSrc that defers setting the background-image style until after real data has loaded.

CASE WHEN countries LIKE '%'+@selCountry+'%' THEN 'national' ELSE 'regional' END

Although, as per your original problem, I'd solve it differently, splitting the content of @selcountry int a table form and joining to it.

The <select> tag only allows the use of predefined entries. The typical solution to your problem is to have one entry labeled 'Other' and a disabled edit field (<input type="text"). Add some JavaScript to enable the edit field only when 'Other' is selected.

It may be possible to somehow create a dropdown that allows direct editing, but IMO that is not worth the effort. If it was, Amazon, Google or Microsoft would be doing it ;-) Just get the job done with the least complicated solution. It as faster (your boss may like that) and usually easier to maintain (you may like that).

I had the same problem:

As I was reluctant to give 0777 to my php directory, I create a tmp directory with rights 0777, where I create the files I need to write to.

My php directory continue to be protected. If somebody hackes the tmp directory, the site continue to work as usual.

You Could try the other format for the case statement

CASE WHEN Product.type_id = 10
THEN
(
  Select Statement
)
ELSE
(
  Other select statement

)  
END
FROM Product 
WHERE Product.product_id = $pid

Foreign keys work with unique constraints as well as primary keys. From Books Online:

A FOREIGN KEY constraint does not have to be linked only to a PRIMARY KEY constraint in another table; it can also be defined to reference the columns of a UNIQUE constraint in another table

For transactional replication, you need the primary key. From Books Online:

Tables published for transactional replication must have a primary key. If a table is in a transactional replication publication, you cannot disable any indexes that are associated with primary key columns. These indexes are required by replication. To disable an index, you must first drop the table from the publication.

Both answers are for SQL Server 2005.

You can use Google Guava:

Maven:

<dependency>
     <artifactId>guava</artifactId>
     <groupId>com.google.guava</groupId>
     <version>14.0.1</version>
</dependency>

Sample code:

String paddedString1 = Strings.padStart("7", 3, '0'); //"007"
String paddedString2 = Strings.padStart("2020", 3, '0'); //"2020"

Note:

Guava is very useful library, it also provides lots of features which related to Collections, Caches, Functional idioms, Concurrency, Strings, Primitives, Ranges, IO, Hashing, EventBus, etc

That meta tag basically specifies which character set a website is written with.

Here is a definition of UTF-8:

UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

I used this method.

Looper.myLooper().quit();

you can try.

When we say

width:auto;

width will never exceed the total width of parent element. Maximum width is it's parent width. Even if we add border, padding and margin, content of element itself will become smaller in order to give space for border, padding and margin. In case if space required for border + padding + margin is greater than total width of parent element then width of content will become zero.

When we say

width:100%;

width of content of element will become 100% of parent element and from now if we add border, padding or margin then it will cause child element to exceed parent element's width and it will starts overflowing out of parent element.

This line of code might not work in IE 8 because of native support problems.

$(".hidden").attr("placeholder", "Type here to search");

You can try importing a JQuery placeholder plugin for this task. Simply import it to your libraries and initiate from the sample code below.

$('input, textarea').placeholder();

Set overflow: hidden; on the body tag like this:

<style type="text/css">
    body {
        overflow: hidden;
    }
</style>

The code above hides both the horizontal and vertical scrollbar.

If you want to hide only the vertical scrollbar, use overflow-y:

<style type="text/css">
    body {
        overflow-y: hidden;
    }
</style>

And if you want to hide only the horizontal scrollbar, use overflow-x:

<style type="text/css">
    body {
        overflow-x: hidden;
    }
</style>

Note: It'll also disable the scrolling feature. Refer to the below answers if you just want to hide the scroll bar, but not the scroll feature.

Try to use r.hasNext() instead of r.hasNextLine():

while(r.hasNext()) {
        scan = r.next();

You might also see this issue if you're trying to package a 64bit project with an MSI installer in VS. ("The reason is because the native shim packaged with the .msi file is a 32-bit executable.")

Yes, there is a problem with pointers. Very likely you're using one that's not initialized properly, but it's also possible that you're messing up your memory management with double frees or some such.

To avoid uninitialized pointers as local variables, try declaring them as late as possible, preferably (and this isn't always possible) when they can be initialized with a meaningful value. Convince yourself that they will have a value before they're being used, by examining the code. If you have difficulty with that, initialize them to a null pointer constant (usually written as NULL or 0) and check them.

To avoid uninitialized pointers as member values, make sure they're initialized properly in the constructor, and handled properly in copy constructors and assignment operators. Don't rely on an init function for memory management, although you can for other initialization.

If your class doesn't need copy constructors or assignment operators, you can declare them as private member functions and never define them. That will cause a compiler error if they're explicitly or implicitly used.

Use smart pointers when applicable. The big advantage here is that, if you stick to them and use them consistently, you can completely avoid writing delete and nothing will be double-deleted.

Use C++ strings and container classes whenever possible, instead of C-style strings and arrays. Consider using .at(i) rather than [i], because that will force bounds checking. See if your compiler or library can be set to check bounds on [i], at least in debug mode. Segmentation faults can be caused by buffer overruns that write garbage over perfectly good pointers.

Doing those things will considerably reduce the likelihood of segmentation faults and other memory problems. They will doubtless fail to fix everything, and that's why you should use valgrind now and then when you don't have problems, and valgrind and gdb when you do.

You can do it with CSS.

Put the buttons in the markup with the Next button first, then the Prev button afterwards.

Then use CSS to position them to appear the way you want.

After trying almost every key on my keyboard:

C:\Users\Tim>cd ^

So it seems to be the ^ key.

You can call it three ways - with parameters, with DEFAULT and via EXECUTE

SET NOCOUNT ON;

DECLARE
@Table  SYSNAME = 'YourTable',
@Schema SYSNAME = 'dbo',
@Rows   INT;

SELECT dbo.TableRowCount( @Table, @Schema )

SELECT dbo.TableRowCount( @Table, DEFAULT )

EXECUTE @Rows = dbo.TableRowCount @Table

SELECT @Rows

A little late to the game, but here's the code I use (in C#):

private static readonly string _Alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
public static int ColumnNameParse(string value)
{
    // assumes value.Length is [1,3]
    // assumes value is uppercase
    var digits = value.PadLeft(3).Select(x => _Alphabet.IndexOf(x));
    return digits.Aggregate(0, (current, index) => (current * 26) + (index + 1));
}

With reacts Hooks:

1. Import

import ReactDOM from 'react-dom';
import React, {useRef} from 'react';

2. Make new hook:

const divRef = useRef<HTMLDivElement>(null);

3. Add new Div

<div ref={divRef}/>

4. Scroll function:

const scrollToDivRef  = () => {
    let node = ReactDOM.findDOMNode(divRef.current) as Element;
    node.scrollIntoView({block: 'start', behavior: 'smooth'});
}

I am not sure why anyone hasn't suggested http://gitblit.com. Pure java based solution, allow HTTP protocol and really easy to setup.

If you're looking to get promise in resource call, you should use

Regions.query().$q.then(function(){ .... })

Update : the promise syntax is changed in current versions which reads

Regions.query().$promise.then(function(){ ..... })

Those who have downvoted don't know what it was and who first added this promise to resource object. I used this feature in late 2012 - yes 2012.

While using the date formats, you may want to keep in mind to always use MM for months and mm for minutes. That should resolve your problem.

Might not solve all the problems in the original question, but since this seems to be the de facto post on how mercurial can amend to previous commit, I'll add my 2 cents worth of information.

If you are like me, and only wish to modify the previous commit message (fix a typo etc) without adding any files, this will work

hg commit -X 'glob:**' --amend

Without any include or exclude patterns hg commit will by default include all files in working directory. Applying pattern -X 'glob:**' will exclude all possible files, allowing only to modify the commit message.

Functionally it is same as git commit --amend when there are no files in index/stage.

If you need the values of i and j, this should work but with less performance than others

for(i;i< 1000; i++){    
    for(j; j< 1000; j++){
        if(condition)
            break;
    }
    if(condition) //the same condition
        break;
}

For what it's worth, I hit a similar error in XCode 9.0.1. I tried uninstalling and reinstalling all my certs, but when I reinstalled, they seemed to remember the trust setting I had previously. What ended up working for me (it seems) was turning off the 'Always Trust' setting of the "Apple Worldwide Developer Relations Certification Authority" cert followed by a reboot. What a cryptic issue!

is better if you sort the Source before Binding it to DropDwonList. but sort DropDownList.Items like this:

    Dim Lista_Items = New List(Of ListItem)

    For Each item As ListItem In ddl.Items
        Lista_Items.Add(item)
    Next

    Lista_Items.Sort(Function(x, y) String.Compare(x.Text, y.Text))

    ddl.Items.Clear()
    ddl.Items.AddRange(Lista_Items.ToArray())

(this case i sort by a string(the item's text), it could be the suplier's name, supplier's id)

the Sort() method is for every List(of ) / List<MyType>, you can use it.

You should define

<uses-permission
    android:name="android.permission.INSTALL_PACKAGES" />

in your manifest, then if whether you are in system partition (/system/app) or you have your application signed by the manufacturer, you are going to have INSTALL_PACKAGES permission.

My suggestion is to create a little android project with 1.5 compatibility level used to call installPackages via reflection and to export a jar with methods to install packages and to call the real methods. Then, by importing the jar in your project you will be ready to install packages.

Angular 2 production workflow with SystemJs builder and gulp

Angular.io have quick start tutorial. I copied this tutorial and extended with some simple gulp tasks for bundling everything to dist folder which can be copied to server and work just like that. I tried to optimize everything to work well on Jenkis CI, so node_modules can be cached and don't need to be copied.

Source code with sample app on Github: https://github.com/Anjmao/angular2-production-workflow

1. Clean typescripts compiled js files and dist folder
2. Compile typescript files inside app folder
3. Use SystemJs bundler to bundle everything to dist folder with generated hashes for browser cache refresh
4. Use gulp-html-replace to replace index.html scripts with bundled versions and copy to dist folder
5. Copy everything inside assets folder to dist folder

Node: While you always can create your own build process, but I highly recommend to use angular-cli, because it have all needed workflows and it works perfectly now. We are already using it in production and don't have any issues with angular-cli at all.

You can nohup it, but I prefer screen.

You need to use proper nesting and then apply styles to it.

• Right click on button and find the exact class nesting for it using (Inspect element using firebug for firefox), (inspect element for chrome).

• Add style to whole bunch of class. Only then it would work

After brew install pyqt, you can brew test pyqt which will use the python you have got in your PATH in oder to do the test (show a Qt window).

For non-brewed Python, you'll have to set your PYTHONPATH as brew info pyqt will tell.

Sometimes it is necessary to open a new shell or tap in order to use the freshly brewed binaries.

I frequently check these issues by printing the sys.path from inside of python: python -c "import sys; print(sys.path)" The $(brew --prefix)/lib/pythonX.Y/site-packages have to be in the sys.path in order to be able to import stuff. As said, for brewed python, this is default but for any other python, you will have to set the PYTHONPATH.

You can do

git config http.sslVerify "false"

in your specific repo to disable SSL certificate checking for that repo only.

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

There are multiple JPA providers in your classpath. Or atleast in your Application server lib folder.

If you are using Maven Check for dependencies using command mentioned here https://stackoverflow.com/a/47474708/3333878

Then fix by removing/excluding unwanted dependency.

If you just have one dependecy in your classpath, then the application server's class loader might be the issue.

As JavaEE application servers like Websphere, Wildfly, Tomee etc., have their own implementations of JPA and other EE Standards, The Class loader might load it's own implementation instead of picking from your classpath in WAR/EAR file.

To avoid this, you can try below steps.

1. Removing the offending jar in Application Servers library path. Proceed with Caution, as it might break other hosted applications.

In Tomee 1.7.5 Plume/ Web it will have bundled eclipselink-2.4.2 in the lib folder using JPA 2.0, but I had to use JPA 2.1 from org.hibernate:hibernate-core:5.1.17, so removed the eclipselink jar and added all related/ transitive dependencies from hibernate core.

2. Add a shared library. and manually add jars to the app server's path. Websphere has this option.

3. In Websphere, execution of class loader can be changed. so making it the application server's classpath to load last i.e, parent last and having your path load first. Can solve this.

Check if your appserver has above features, before proceeding with first point.

Ibm websphere References :

https://www.ibm.com/support/knowledgecenter/SSEQTP_9.0.5/com.ibm.websphere.base.doc/ae/trun_classload_server.html

https://www.ibm.com/support/pages/how-create-shared-library-and-associate-it-application-server-or-enterprise-application-websphere-application-server

It has to do with the way the post-increment operator works. It returns the value of i and then increments the value.

For whom are using Spring Boot, you can configure the default behaviour of Jackson by using the Jackson2ObjectMapperBuilder.

For example :

@Bean
public Jackson2ObjectMapperBuilder configureObjectMapper() {
    Jackson2ObjectMapperBuilder oMapper = new Jackson2ObjectMapperBuilder();
    oMapper.failOnUnknownProperties(false);
    return oMapper;
}

Then you can autowire the ObjectMapper everywhere you need it (by default, this object mapper will also be used for http content conversion).

Obfuscation is only adding another layer of potential bugs and security vulnerabilities to your program. Please don't do it.

The kind of people who write obfuscation software usually seem very sketchy and non-skilled anyway.

If your code is "great", crackers will go through great lengths to spread it, regardless of whether or not it is obfuscated. If nobody knows/cares about your code, they probably won't, either.

You can use Jasypt to encrypt properties, so you could have your property like this:

db.password=ENC(XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=)

Jasypt allows you to encrypt your properties using different algorithms, once you get the encrypted property you put inside the ENC(...). For instance, you can encrypt this way through Jasypt using the terminal:

encrypted-pwd$ java -cp ~/.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar  org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="contactspassword" password=supersecretz algorithm=PBEWithMD5AndDES

----ENVIRONMENT-----------------

Runtime: Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 24.45-b08



----ARGUMENTS-------------------

algorithm: PBEWithMD5AndDES
input: contactspassword
password: supersecretz



----OUTPUT----------------------

XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=

To easily configure it with Spring Boot you can use its starter jasypt-spring-boot-starter with group ID com.github.ulisesbocchio

Keep in mind, that you will need to start your application using the same password you used to encrypt the properties. So, you can start your app this way:

mvn -Djasypt.encryptor.password=supersecretz spring-boot:run

Or using the environment variable (thanks to spring boot relaxed binding):

export JASYPT_ENCRYPTOR_PASSWORD=supersecretz
mvn spring-boot:run

You can check below link for more details:

https://www.ricston.com/blog/encrypting-properties-in-spring-boot-with-jasypt-spring-boot/

To use your encrypted properties in your app just use it as usual, use either method you like (Spring Boot wires the magic, anyway the property must be of course in the classpath):

Using @Value annotation

@Value("${db.password}")
private String password;

Or using Environment

@Autowired
private Environment environment;

public void doSomething(Environment env) {
    System.out.println(env.getProperty("db.password"));
}

Update: for production environment, to avoid exposing the password in the command line, since you can query the processes with ps, previous commands with history, etc etc. You could:

• Create a script like this: touch setEnv.sh
• Edit setEnv.sh to export the JASYPT_ENCRYPTOR_PASSWORD variable

  #!/bin/bash

  export JASYPT_ENCRYPTOR_PASSWORD=supersecretz

• Execute the file with . setEnv.sh
• Run the app in background with mvn spring-boot:run &
• Delete the file setEnv.sh
• Unset the previous environment variable with: unset JASYPT_ENCRYPTOR_PASSWORD

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

Starting with the mobile version first, you can achieve what you want, most of the time.

You have to insert the elements using the insert method present in vectors STL, check the below program to add the elements to it, and you can use in the same way in your program.

#include <iostream>
#include <vector>
#include <string.h>

int main ()
{
  std::vector<std::string> myvector ;
  std::vector<std::string>::iterator it;

   it = myvector.begin();
  std::string myarray [] = { "Hi","hello","wassup" };
  myvector.insert (myvector.begin(), myarray, myarray+3);

  std::cout << "myvector contains:";
  for (it=myvector.begin(); it<myvector.end(); it++)
    std::cout << ' ' << *it;
    std::cout << '\n';

  return 0;
}

There's also oct2py which can call .m files within python

https://pypi.python.org/pypi/oct2py

It requires GNU Octave, which is highly compatible with MATLAB.

It's not an answer, but...

To get datetime components individually, better use datetime.timetuple:

time = datetime.now()
time.timetuple()
#-> time.struct_time(
#    tm_year=2014, tm_mon=9, tm_mday=7, 
#    tm_hour=2, tm_min=38, tm_sec=5, 
#    tm_wday=6, tm_yday=250, tm_isdst=-1
#)

It's now easy to get the parts:

ts = time.timetuple()
ts.tm_year
ts.tm_mon
ts.tm_mday
ts.tm_hour
ts.tm_min
ts.tm_sec

One can use Redirect too for this purpose

Redirect 301 / www.example.com/store

Or Alias for mapping

Alias / /store

You can use pandas.cut:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
   percentage     binned
0       46.50   (25, 50]
1       44.20   (25, 50]
2      100.00  (50, 100]
3       42.12   (25, 50]

s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50]     3
(50, 100]    1
(10, 25]     0
(5, 10]      0
(1, 5]       0
(0, 1]       0
Name: percentage, dtype: int64

s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1]       0
(1, 5]       0
(5, 10]      0
(10, 25]     0
(25, 50]     3
(50, 100]    1
dtype: int64

By default cut return categorical.

Series methods like Series.value_counts() will use all categories, even if some categories are not present in the data, operations in categorical.

Maybe this will help someone else, but I've seen this error when the RHS of the mapping contains a colon without enclosing quotes, such as:

someKey: another key: Change to make today: work out more

should be

someKey: another key: "Change to make today: work out more"

Found this works in Safari. SVG only colors in with background-color where an element's bounding box covers. So, give it a border (stroke) with a zero pixel boundary. It fills in the whole thing for you with your background-color.

<svg style='stroke-width: 0px; background-color: blue;'> </svg>

Use:

android:imeActionLabel="Done"
android:singleLine="true" 

Use boost::filesystem, that will give you a portable way of doing those kinds of things and abstract away all ugly details for you.

Microsoft just added an official prelease version of exactly what you're looking for (called a MultiDictionary) available through NuGet here: https://www.nuget.org/packages/Microsoft.Experimental.Collections/

Info on usage and more details can be found through the official MSDN blog post here: http://blogs.msdn.com/b/dotnet/archive/2014/06/20/would-you-like-a-multidictionary.aspx

I'm the developer for this package, so let me know either here or on MSDN if you have any questions about performance or anything.

Hope that helps.

Update

The MultiValueDictionary is now on the corefxlab repo, and you can get the NuGet package from this MyGet feed.

I made my solution based on the posts I found here with Google. And I thought there is no harm to post mine as well even if it is an old thread.

The only plus this code gives is that it can iterate through sub-directories as well.

import java.io.File;
import java.io.FileFilter;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import org.apache.commons.io.filefilter.DirectoryFileFilter;
import org.apache.commons.io.filefilter.WildcardFileFilter;

Method is as follows:

List <File> exploreThis(String dirPath){

    File topDir = new File(dirPath);

    List<File> directories = new ArrayList<>();
    directories.add(topDir);

    List<File> textFiles = new ArrayList<>();

    List<String> filterWildcards = new ArrayList<>();
    filterWildcards.add("*.txt");
    filterWildcards.add("*.doc");

    FileFilter typeFilter = new WildcardFileFilter(filterWildcards);

    while (directories.isEmpty() == false)
    {
        List<File> subDirectories = new ArrayList();

        for(File f : directories)
        {
            subDirectories.addAll(Arrays.asList(f.listFiles((FileFilter)DirectoryFileFilter.INSTANCE)));
            textFiles.addAll(Arrays.asList(f.listFiles(typeFilter)));
        }

        directories.clear();
        directories.addAll(subDirectories);
    }

    return textFiles;
}

In my case, solution here: (for people who concerned) login to postgres:

sudo -i -u postgres
psql
ALTER USER postgres WITH PASSWORD 'postgres'; # type your password here

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

The problem with the two Powershell answers here is that the prefix can end up being duplicated since the script will potentially run over the file both before and after it has been renamed, depending on the directory being resorted as the renaming process runs. To get around this, simply use the -Exclude option:

Get-ChildItem -Exclude "house chores-*" | rename-item -NewName { "house chores-" + $_.Name }

This will prevent the process from renaming any one file more than once.

Here is an updated method with syntax that is more common in python code. It also prevents you from opening the same file multiple times.

import pandas as pd

sheet1, sheet2 = None, None
with pd.ExcelFile("PATH\FileName.xlsx") as reader:
    sheet1 = pd.read_excel(reader, sheet_name='Sheet1')
    sheet2 = pd.read_excel(reader, sheet_name='Sheet2')

This has been fully answered here.

See Oracle's docs on SELECT to see how subquery factoring works, and Mark's example:

WITH employee AS (SELECT * FROM Employees)
SELECT * FROM employee WHERE ID < 20
UNION ALL
SELECT * FROM employee WHERE Sex = 'M'

Comment by @Niagaradad helped me. I was entering the wrong password the whole time.

Notice the error message

ERROR 1045 (28000): Access denied for user 'ayaz'@'localhost' (using password: YES)

It says, Password: Yes. That means I am sending the password to SQL and that is wrong.

Usually root account doesn't have password if you haven't set one. If you have installed mysql via homebrew then root account won't have a password.

Here is the comment.

so, not exactly the same then. NO means you are not sending a password to MySQL. YES means you are sending a password to MySQL but the incorrect one. Did you specifically set a password for the mysql root user when you installed MySQL? By default there is no password so you can use mysql -u root -p and hit enter.

It's working with

Set WSHELL = CreateObject("Wscript.Shell")
WSHELL.Exec("Application_Path")

But what should be the parameter in case we want to enter the application name only

e.g in case of Internet Explorer

WSHELL.Run("iexplore")

For everyone coming here for having similar question, the following works great and I have it in my library the last years:

   g3.utils = g3.utils || {};

When people say don't put logic in views, they're usually referring to business logic, not rendering logic. In my humble opinion, I think using @foreach in views is perfectly fine.

To expound slightly on GlennG's very helpful answer (translating the syntax from C# to VB.Net is not always "obvious") you can also decorate individual class properties to manage how null values are handled. If you do this don't use the global JsonSerializerSettings from GlennG's suggestion, otherwise it will override the individual decorations. This comes in handy if you want a null item to appear in the JSON so the consumer doesn't have to do any special handling. If, for example, the consumer needs to know an array of optional items is normally available, but is currently empty... The decoration in the property declaration looks like this:

<JsonPropertyAttribute("MyProperty", DefaultValueHandling:=NullValueHandling.Include)> Public Property MyProperty As New List(of String)

For those properties you don't want to have appear at all in the JSON change :=NullValueHandling.Include to :=NullValueHandling.Ignore. By the way - I've found that you can decorate a property for both XML and JSON serialization just fine (just put them right next to each other). This gives me the option to call the XML serializer in dotnet or the NewtonSoft serializer at will - both work side-by-side and my customers have the option to work with XML or JSON. This is slick as snot on a doorknob since I have customers that require both!

You can directly change text or string to proper using this simple method, after checking for null or empty string values in order to eliminate errors:

public string textToProper(string text)
{
    string ProperText = string.Empty;
    if (!string.IsNullOrEmpty(text))
    {
        ProperText = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(text);
    }
    else
    {
        ProperText = string.Empty;
    }
    return ProperText;
}

The following should work:

public static void main(String[] args)
{
    final String title = "Test Window";
    final int width = 1200;
    final int height = width / 16 * 9;

    //Creating the frame.
    JFrame frame = new JFrame(title);

    frame.setSize(width, height);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLocationRelativeTo(null);
    frame.setResizable(false);
    frame.setVisible(true);

    //Creating the canvas.
    Canvas canvas = new Canvas();

    canvas.setSize(width, height);
    canvas.setBackground(Color.BLACK);
    canvas.setVisible(true);
    canvas.setFocusable(false);


    //Putting it all together.
    frame.add(canvas);

    canvas.createBufferStrategy(3);

    boolean running = true;

    BufferStrategy bufferStrategy;
    Graphics graphics;

    while (running) {
        bufferStrategy = canvas.getBufferStrategy();
        graphics = bufferStrategy.getDrawGraphics();
        graphics.clearRect(0, 0, width, height);

        graphics.setColor(Color.GREEN);
        graphics.drawString("This is some text placed in the top left corner.", 5, 15);

        bufferStrategy.show();
        graphics.dispose();
    }
}

Note that if you're not using the full jquery UI library, this can be triggered if you're missing Widget, Menu, Position, or Core. There might be different dependencies depending on your version of jQuery UI

The main difference is that Boolean is an object and boolean is an primitive.

• Object default value is null;
• boolean default value is false;

While @A_Di-Matteo answer does work for non multimodule I have a solution for multimodules.

The solution is to override every plugin configuration so that it binds to the phase of none with the exception of the jar/war/ear plugin and of course the deploy plugin. Even if you do have a single module my rudimentary tests show this to be a little faster (for reasons I don't know) performance wise.

Thus the trick is to make a profile that does the above that is activated when you only want to deploy.

Below is an example from one of my projects which uses the shade plugin and thus I had to re-override the jar plugin not to overwrite:

    <profile>
      <id>deploy</id>
      <activation>
        <property>
          <name>buildStep</name>
          <value>deploy</value>
        </property>
      </activation>

        </plugins>
      </build>
    </profile>

Now if I run mvn deploy -Pdeploy it will only run the jar and deploy plugins.

How you can figure out which plugins you need to override is to run deploy and look at the log to see which plugins are running. Make sure to keep track of the id of the plugin configuration which is parens after the name of the plugin.

I used this and in worked for me!

$("checkbox selector").click(function() {
    if($(this).prop('checked')==true){
       do what you need!
    }
});

You can simply use subprocess.getoutput(python3 --version)

import subprocess as sp
print(sp.getoutput(python3 --version))

# or however it suits your needs!
py3_version = sp.getoutput(python3 --version)

def check_version(name, version):...

check_version('python3', py3_version)

For more information and ways to do this without depending on the __version__ attribute:

Assign output of os.system to a variable and prevent it from being displayed on the screen

You can also use subprocess.check_output() which raises an error when the subprocess returns anything other than exit code 0:

https://docs.python.org/3/library/subprocess.html#check_output()

Add one more line after initializing file object

File fnew = new File("../playlist/" + existingPlaylist.getText() + ".txt");
fnew.createNewFile();

Couldn't that just be done by only using a positive button?

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Look at this dialog!")
       .setCancelable(false)
       .setPositiveButton("OK", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });
AlertDialog alert = builder.create();
alert.show();

Your second DELETE query was nearly correct. Just be sure to put the table name (or an alias) between DELETE and FROM to specify which table you are deleting from. This is simpler than using a nested SELECT statement like in the other answers.

Corrected Query (option 1: using full table name):

DELETE tableA
FROM tableA
INNER JOIN tableB u on (u.qlabel = tableA.entityrole AND u.fieldnum = tableA.fieldnum) 
WHERE (LENGTH(tableA.memotext) NOT IN (8,9,10)
OR tableA.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')

Corrected Query (option 2: using an alias):

DELETE q
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) 
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')

9.3 Context per request

Entity Framework’s contexts are meant to be used as short-lived instances in order to provide the most optimal performance experience. Contexts are expected to be short lived and discarded, and as such have been implemented to be very lightweight and reutilize metadata whenever possible. In web scenarios it’s important to keep this in mind and not have a context for more than the duration of a single request. Similarly, in non-web scenarios, context should be discarded based on your understanding of the different levels of caching in the Entity Framework. Generally speaking, one should avoid having a context instance throughout the life of the application, as well as contexts per thread and static contexts.

I use this to set Profile image on each page.

On first page set value as:

localStorage.setItem("imageurl", "ur image url");

or on second page get value as :

var imageurl=localStorage.getItem("imageurl");
document.getElementById("profilePic").src = (imageurl);

As pointed out, "&" in python performs a bitwise and operation, just as it does in C#. and is the appropriate equivalent to the && operator.

Since we're dealing with booleans (i == 5 is True and ii == 10 is also True), you may wonder why this didn't either work anyway (True being treated as an integer quantity should still mean True & True is a True value), or throw an exception (eg. by forbidding bitwise operations on boolean types)

The reason is operator precedence. The "and" operator binds more loosely than ==, so the expression: "i==5 and ii==10" is equivalent to: "(i==5) and (ii==10)"

However, bitwise & has a higher precedence than "==" (since you wouldn't want expressions like "a & 0xff == ch" to mean "a & (0xff == ch)"), so the expression would actually be interpreted as:

if i == (5 & ii) == 10:

Which is using python's operator chaining to mean: does the valuee of ii anded with 5 equal both i and 10. Obviously this will never be true.

You would actually get (seemingly) the right answer if you had included brackets to force the precedence, so:

if (i==5) & (ii=10)

would cause the statement to be printed. It's the wrong thing to do, however - "&" has many different semantics to "and" - (precedence, short-cirtuiting, behaviour with integer arguments etc), so it's fortunate that you caught this here rather than being fooled till it produced less obvious bugs.

There is a difference in C# if you are using the variable in a lambda, etc. But in general the compiler will basically do the same thing, assuming the variable is only used within the loop.

Given that they are basically the same: Note that version b makes it much more obvious to readers that the variable isn't, and can't, be used after the loop. Additionally, version b is much more easily refactored. It is more difficult to extract the loop body into its own method in version a. Moreover, version b assures you that there is no side effect to such a refactoring.

Hence, version a annoys me to no end, because there's no benefit to it and it makes it much more difficult to reason about the code...

Compile file, run and delete after (my preference)

$ gcc timeout.c -o timeout && ./timeout && rm timeout

Try run it for yourself to see result.

It can be resolved by below simple code with Stream and Try in AbacusUtil:

It could be dependent upon what is supported by the module you are trying to compile. If your makefile is generated by using autotools, use:

--prefix=<myinstalldir>

when running the ./configure

some packages allow you to also override when running:

make prefix=<myinstalldir>

however, if your not using ./configure, only way to know for sure is to open up the makefile and check. It should be one of the first few variables at the top.

Here's how to fix this error when launching Eclipse:

Version 1.6.0_65 of the JVM is not suitable for this product. Version: 1.7 or greater is required.

1. Go and install latest JDK

2. Make sure you have installed 64 bit Eclipse

It's usually to namespace (see later) and control the visibility of member functions and/or variables. Think of it like an object definition. The technical name for it is an Immediately Invoked Function Expression (IIFE). jQuery plugins are usually written like this.

In Javascript, you can nest functions. So, the following is legal:

function outerFunction() {
   function innerFunction() {
      // code
   }
}

Now you can call outerFunction(), but the visiblity of innerFunction() is limited to the scope of outerFunction(), meaning it is private to outerFunction(). It basically follows the same principle as variables in Javascript:

var globalVariable;

function someFunction() {
   var localVariable;
}

Correspondingly:

function globalFunction() {

   var localFunction1 = function() {
       //I'm anonymous! But localFunction1 is a reference to me!
   };

   function localFunction2() {
      //I'm named!
   }
}

In the above scenario, you can call globalFunction() from anywhere, but you cannot call localFunction1 or localFunction2.

What you're doing when you write (function() { ... })(), is you're making the code inside the first set of parentheses a function literal (meaning the whole "object" is actually a function). After that, you're self-invoking the function (the final ()) that you just defined. So the major advantage of this as I mentioned before, is that you can have private methods/functions and properties:

(function() {
   var private_var;

   function private_function() {
     //code
   }
})();

In the first example, you would explicitly invoke globalFunction by name to run it. That is, you would just do globalFunction() to run it. But in the above example, you're not just defining a function; you're defining and invoking it in one go. This means that when the your JavaScript file is loaded, it is immediately executed. Of course, you could do:

function globalFunction() {
    // code
}
globalFunction();

The behavior would largely be the same except for one significant difference: you avoid polluting the global scope when you use an IIFE (as a consequence it also means that you cannot invoke the function multiple times since it doesn't have a name, but since this function is only meant to be executed once it really isn't an issue).

The neat thing with IIFEs is that you can also define things inside and only expose the parts that you want to the outside world so (an example of namespacing so you can basically create your own library/plugin):

var myPlugin = (function() {
 var private_var;

 function private_function() {
 }

 return {
    public_function1: function() {
    },
    public_function2: function() {
    }
 }
})()

Now you can call myPlugin.public_function1(), but you cannot access private_function()! So pretty similar to a class definition. To understand this better, I recommend the following links for some further reading:

• Namespacing your Javascript
• Private members in Javascript (by Douglas Crockford)

EDIT

I forgot to mention. In that final (), you can pass anything you want inside. For example, when you create jQuery plugins, you pass in jQuery or $ like so:

(function(jQ) { ... code ... })(jQuery) 

So what you're doing here is defining a function that takes in one parameter (called jQ, a local variable, and known only to that function). Then you're self-invoking the function and passing in a parameter (also called jQuery, but this one is from the outside world and a reference to the actual jQuery itself). There is no pressing need to do this, but there are some advantages:

• You can redefine a global parameter and give it a name that makes sense in the local scope.
• There is a slight performance advantage since it is faster to look things up in the local scope instead of having to walk up the scope chain into the global scope.
• There are benefits for compression (minification).

Earlier I described how these functions run automatically at startup, but if they run automatically who is passing in the arguments? This technique assumes that all the parameters you need are already defined as global variables. So if jQuery wasn't already defined as a global variable this example would not work. As you might guess, one things jquery.js does during its initialization is define a 'jQuery' global variable, as well as its more famous '$' global variable, which allows this code to work after jQuery has been included.

Did you try CSS overflow property?

overflow: scroll; /* Scrollbar are always visible */
overflow: auto;   /* Scrollbar is displayed as it's needed */

UPDATE
As other users are pointing out, this is not enough to add the scrollbars.
So please, see and upvote comments and answers below.

A python-like solution, which allows you to use negative index,

var str = "Hello world!"
str[-1]        // "!"

could be:

extension String {
    subscript (var index:Int)->Character{
        get {
            let n = distance(self.startIndex, self.endIndex)
            index %= n
            if index < 0 { index += n }
            return self[advance(startIndex, index)]
        }
    }
}

By the way, it may be worth it to transpose the whole python's slice notation

I answer this coming from a component-based architecture, where an organisation may be running many components that may rely on each other. During a propagating failure, logging levels should help to identify both which components are affected and which are a root cause.

• ERROR - This component has had a failure and the cause is believed to be internal (any internal, unhandled exception, failure of encapsulated dependency... e.g. database, REST example would be it has received a 4xx error from a dependency). Get me (maintainer of this component) out of bed.

• WARN - This component has had a failure believed to be caused by a dependent component (REST example would be a 5xx status from a dependency). Get the maintainers of THAT component out of bed.

• INFO - Anything else that we want to get to an operator. If you decide to log happy paths then I recommend limiting to 1 log message per significant operation (e.g. per incoming http request).

For all log messages be sure to log useful context (and prioritise on making messages human readable/useful rather than having reams of "error codes")

• DEBUG (and below) - Shouldn't be used at all (and certainly not in production). In development I would advise using a combination of TDD and Debugging (where necessary) as opposed to polluting code with log statements. In production, the above INFO logging, combined with other metrics should be sufficient.

A nice way to visualise the above logging levels is to imagine a set of monitoring screens for each component. When all running well they are green, if a component logs a WARNING then it will go orange (amber) if anything logs an ERROR then it will go red.

In the event of an incident you should have one (root cause) component go red and all the affected components should go orange/amber.

"The project works on the laptop, but now having copied the updated source code onto the desktop ..."

I did something similar, creating two versions of a project and copying files between them. It gave me the same error.

My solution was to go into the project file, where I discovered that what had looked like this:

<Compile Include="App_Code\Common\Pair.cs" />
<Compile Include="App_Code\Common\QueryCommand.cs" />

Now looked like this:

<Content Include="App_Code\Common\Pair.cs">
  <SubType>Code</SubType>
</Content>
<Content Include="App_Code\Common\QueryCommand.cs">
  <SubType>Code</SubType>
</Content>

When I changed them back, Visual Studio was happy again.

Directly use df.fillna(df.mean()) to fill all the null value with mean

If you want to fill null value with mean of that column then you can use this

suppose x=df['Item_Weight'] here Item_Weight is column name

here we are assigning (fill null values of x with mean of x into x)

df['Item_Weight'] = df['Item_Weight'].fillna((df['Item_Weight'].mean()))

If you want to fill null value with some string then use

here Outlet_size is column name

df.Outlet_Size = df.Outlet_Size.fillna('Missing')

What OS you are using and which Webserver? On Linux and Apache you can find the apache error_log in /var/log/apache2/

Send the data from the form:

$("#change_section_type").live "change", ->
url = $(this).attr("data-url")
postData = $(this).parents("#contract_setting_form").serializeArray()
$.ajax
  type: "PUT"
  url: url
  dataType: "script"
  data: postData

Here you go, create a .bat file with the following in it :

@echo off
REM Creating a Newline variable (the two blank lines are required!)
set NLM=^


set NL=^^^%NLM%%NLM%^%NLM%%NLM%
REM Example Usage:
echo There should be a newline%NL%inserted here.

echo.
pause

You should see output like the following:

There should be a newline
inserted here.

Press any key to continue . . .

You only need the code between the REM statements, obviously.

if you have a list a and then following statements

list<int>::iterator it; // declare an iterator
    list<int>::const_iterator cit; // declare an const iterator 
    it=a.begin();
    cit=a.begin();

you can change the contents of the element in the list using “it” but not “cit”, that is you can use “cit” for reading the contents not for updating the elements.

*it=*it+1;//returns no error
    *cit=*cit+1;//this will return error

I know this is an old question, but this is still a problem I keep walking into, and yet there is still no clear solution to do this correctly when using async/await in an async void signature method.

However, I noticed that .Wait() is working properly inside the void method.

and since async void and void have the same signature, you might need to do the following.

void LoadBlahBlah()
{
    blah().Wait(); //this blocks
}

Confusingly enough async/await does not block on the next code.

async void LoadBlahBlah()
{
    await blah(); //this does not block
}

When you decompile your code, my guess is that async void creates an internal Task (just like async Task), but since the signature does not support to return that internal Tasks

this means that internally the async void method will still be able to "await" internally async methods. but externally unable to know when the internal Task is complete.

So my conclusion is that async void is working as intended, and if you need feedback from the internal Task, then you need to use the async Task signature instead.

hopefully my rambling makes sense to anybody also looking for answers.

Edit: I made some example code and decompiled it to see what is actually going on.

static async void Test()
{
    await Task.Delay(5000);
}

static async Task TestAsync()
{
    await Task.Delay(5000);
}

Turns into (edit: I know that the body code is not here but in the statemachines, but the statemachines was basically identical, so I didn't bother adding them)

private static void Test()
{
    <Test>d__1 stateMachine = new <Test>d__1();
    stateMachine.<>t__builder = AsyncVoidMethodBuilder.Create();
    stateMachine.<>1__state = -1;
    AsyncVoidMethodBuilder <>t__builder = stateMachine.<>t__builder;
    <>t__builder.Start(ref stateMachine);
}
private static Task TestAsync()
{
    <TestAsync>d__2 stateMachine = new <TestAsync>d__2();
    stateMachine.<>t__builder = AsyncTaskMethodBuilder.Create();
    stateMachine.<>1__state = -1;
    AsyncTaskMethodBuilder <>t__builder = stateMachine.<>t__builder;
    <>t__builder.Start(ref stateMachine);
    return stateMachine.<>t__builder.Task;
}

neither AsyncVoidMethodBuilder or AsyncTaskMethodBuilder actually have any code in the Start method that would hint of them to block, and would always run asynchronously after they are started.

meaning without the returning Task, there would be no way to check if it is complete.

as expected, it only starts the Task running async, and then it continues in the code. and the async Task, first it starts the Task, and then it returns it.

so I guess my answer would be to never use async void, if you need to know when the task is done, that is what async Task is for.

For you Win8 users out there, if you follow the steps in the accepted answer, console spits out a message at you saying "thou shalt not use the command-line to execute this command" (paraphrasing). Instead, access the Programs & Features via Control Panel (or Windows + R > appwiz.cpl), click 'Turn Windows features on or off', and make sure you have the following installed:

Internet Information Services
  > World Wide Web Services
    > Application Development Features
      > ASP.NET 4.5

This will check a bunch of other options as well. As soon as I installed these features, and ran VS2012 with elevated permissions, I was able to launch my app successfully.

Let me try to tackle @balpha parsing problem. I would use parentheses around the multiline lamda. If there is no parentheses, the lambda definition is greedy. So the lambda in

map(lambda x:
      y = x+1
      z = x-1
      y*z,
    [1,2,3]))

returns a function that returns (y*z, [1,2,3])

But

map((lambda x:
      y = x+1
      z = x-1
      y*z)
    ,[1,2,3]))

means

map(func, [1,2,3])

where func is the multiline lambda that return y*z. Does that work?

My idea is let two JavaScript call function through DOM.

The way to do it is simple ... We just need to define hidden js_ipc html tag. After the callee register click from the hidden js_ipc tag, then The caller can dispatch the click event to trigger callee. And the argument is save in the event that you want to pass.

When we need to use above way ?

Sometime, the two javascript code is very complicated to integrate and so many async code there. And different code use different framework but you still need to have a simple way to integrate them together.

So, in that case, it is not easy to do it.

In my project's implementation, I meet this case and it is very complicated to integrate. And finally I found out that we can let two javascript call each other through DOM.

I demonstrate this way in this git code. you can get it through this way. (Or read it from https://github.com/milochen0418/javascript-ipc-demo)

git clone https://github.com/milochen0418/javascript-ipc-demo
cd javascript-ipc-demo
git checkout 5f75d44530b4145ca2b06105c6aac28b764f066e

Anywhere, Here, I try to explain by the following simple case. I hope that this way can help you to integrate two different javascript code easier than before there is no any JavaScript library to support communication between two javascript file that made by different team.

<html>
<head>
    <link rel="stylesheet" type="text/css" href="css/style.css" />
</head>
<body>
    <div id="js_ipc" style="display:none;"></div>
    <div id="test_btn" class="btn">
        <a><p>click to test</p></a>
    </div>    
</body>
<script src="js/callee.js"></script>
<script src="js/caller.js"></script>
</html>

And the code css/style.css

.btn {
    background-color:grey;
    cursor:pointer;
    display:inline-block;
}

js/caller.js

function caller_add_of_ipc(num1, num2) {
    var e = new Event("click");
    e.arguments = arguments;
    document.getElementById("js_ipc").dispatchEvent(e);
}
document.getElementById("test_btn").addEventListener('click', function(e) {
    console.log("click to invoke caller of IPC");
    caller_add_of_ipc(33, 22);      
});

js/callee.js

document.getElementById("js_ipc").addEventListener('click', (e)=>{
    callee_add_of_ipc(e.arguments);
});    
function callee_add_of_ipc(arguments) {
    let num1 = arguments[0];
    let num2 = arguments[1];
    console.log("This is callee of IPC -- inner-communication process");
    console.log( "num1 + num2 = " + (num1 + num2));
}

In R the equivalent function is seq and you can use it with the option by:

seq(from = 5, to = 100, by = 5)
# [1]   5  10  15  20  25  30  35  40  45  50  55  60  65  70  75  80  85  90  95 100

In addition to by you can also have other options such as length.out and along.with.

length.out: If you want to get a total of 10 numbers between 0 and 1, for example:

seq(0, 1, length.out = 10)
# gives 10 equally spaced numbers from 0 to 1

along.with: It takes the length of the vector you supply as input and provides a vector from 1:length(input).

seq(along.with=c(10,20,30))
# [1] 1 2 3

Although, instead of using the along.with option, it is recommended to use seq_along in this case. From the documentation for ?seq

seq is generic, and only the default method is described here. Note that it dispatches on the class of the first argument irrespective of argument names. This can have unintended consequences if it is called with just one argument intending this to be taken as along.with: it is much better to use seq_along in that case.

seq_along: Instead of seq(along.with(.))

seq_along(c(10,20,30))
# [1] 1 2 3

Hope this helps.

Check if your Windows has pending updates. After the restart, installation worked as expected.

System variables can be set through CMD and registry For ex. reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH

All the commonly used CMD codes and system variables are given here: Set Windows system environment variables using CMD.

Open CMD and type Set

You will get all the values of system variable.

This is a late addition but I was looking for information on the scale function myself and though it might help somebody else as well.

To modify the response from Ricardo Saporta a little bit.
Scaling is not done using standard deviation, at least not in version 3.6.1 of R, I base this on "Becker, R. (2018). The new S language. CRC Press." and my own experimentation.

X.man.scaled <- X/sqrt(sum(X^2)/(length(X)-1))
X.aut.scaled <- scale(X, center = F)

The result of these rows are exactly the same, I show it without centering because of simplicity.

I would respond in a comment but did not have enough reputation.

Django forms module uses __call__ method nicely to implement a consistent API for form validation. You can write your own validator for a form in Django as a function.

def custom_validator(value):
    #your validation logic

Django has some default built-in validators such as email validators, url validators etc., which broadly fall under the umbrella of RegEx validators. To implement these cleanly, Django resorts to callable classes (instead of functions). It implements default Regex Validation logic in a RegexValidator and then extends these classes for other validations.

class RegexValidator(object):
    def __call__(self, value):
        # validation logic

class URLValidator(RegexValidator):
    def __call__(self, value):
        super(URLValidator, self).__call__(value)
        #additional logic

class EmailValidator(RegexValidator):
    # some logic

Now both your custom function and built-in EmailValidator can be called with the same syntax.

for v in [custom_validator, EmailValidator()]:
    v(value) # <-----

As you can see, this implementation in Django is similar to what others have explained in their answers below. Can this be implemented in any other way? You could, but IMHO it will not be as readable or as easily extensible for a big framework like Django.

Looking at your example, I think this is what you want:

var dict = TableObj.ToDictionary(t => t.Key, t=> t.TimeStamp);

I had a similar issue that was resolved by unchecking the option in java advanced security for "Use SSL 2.0 compatible ClientHello format.

Fix ImageView's size with dp or fill_parent and set android:scaleType to fitXY.

This helped to me (in ionic, but idea is the same) https://mhartington.io/post/setting-input-focus/

in template:

<ion-item>
      <ion-label>Home</ion-label>
      <ion-input #input type="text"></ion-input>
</ion-item>
<button (click)="focusInput(input)">Focus</button>

in controller:

  focusInput(input) {
    input.setFocus();
  }

When an error occurs, the execution will continue on the next line without interrupting the script.

I had the similar problem my application displays message notifications. When there are multiple notifications and clicking each notification it displays that notification detail in a view message activity. I solved the problem of same extra parameters is being received in view message intent.

Here is the code which fixed this. Code for creating the notification Intent.

 Intent notificationIntent = new Intent(getApplicationContext(), viewmessage.class);
    notificationIntent.putExtra("NotificationMessage", notificationMessage);
    notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(getApplicationContext(),notificationIndex,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.setLatestEventInfo(getApplicationContext(), notificationTitle, notificationMessage, pendingNotificationIntent);

Code for view Message Activity.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    onNewIntent(getIntent());
}

@Override
public void onNewIntent(Intent intent){
    Bundle extras = intent.getExtras();
    if(extras != null){
        if(extras.containsKey("NotificationMessage"))
        {
            setContentView(R.layout.viewmain);
            // extract the extra-data in the Notification
            String msg = extras.getString("NotificationMessage");
            txtView = (TextView) findViewById(R.id.txtMessage);
            txtView.setText(msg);
        }
    }


}

I see two problems:

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:

DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.

Also, you'll need to specify your id column as a key :

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id) );

I've created my own dark color scheme (based on Oblivion from gedit), which I think is very nice to work with.

Preview & details at: http://www.rogerdudler.com/?p=362

We're happy to announce the beta of eclipsecolorthemes.org, a new website to download, create and maintain Eclipse color themes / schemes. The theme editor allows you to copy an existing theme and edit the colors with a live preview of your changes on specific editors. The downloadable themes support a lot of editors (PHP, Java, SQL, Ant, text, HTML, CSS, and more to follow)

There's a growing list of themes already available on the site:

• Zenburn
• Oblivion
• Inkpot
• Vibrant Ink

This answer may appear at the surface to be unrelated, but there is an indirect cause of this error message.

First, the "Uses VFP register..." error message is directly caused from mixing mfloat-abi=soft and mfloat-abi=hard options within your build. This setting must be consistent for all objects that are to be linked. This fact is well covered in the other answers to this question.

The indirect cause of this error may be due to the Eclipse editor getting confused by a self-inflicted error in the project's ".cproject" file. The Eclipse editor frequently reswizzles file links and sometimes it breaks itself when you make changes to your directory structures or file locations. This can also affect the path settings to your gcc compiler - and only for a subset of your project's files. While I'm not yet sure of exactly what causes this failure, replacing the .cproject file with a backup copy corrected this problem for me. In my case I noticed .java.null.pointer errors after adding an include directory path and started receiving the "VFP register error" messages out of the blue. In the build log I noticed that a different path to the gcc compiler was being used for some of my sources that were local to the workspace, but not all of them!? The two gcc compilers were using different float settings for unknown reasons - hence the VFP register error.

I compared the .cproject settings with a older copy and observed differences in entries for the sources causing the trouble - even though the overriding of project settings was disabled. By replacing the .cproject file with the old version the problem went away, and I'm leaving this answer as a reminder of what happened.

Or, if you are really about lines:

System.IO.File also contains a static method WriteAllLines, so you could do:

IList<string> myLines = new List<string>()
{
    "line1",
    "line2",
    "line3",
};

File.WriteAllLines("./foo", myLines);

Call the procedure SP_1 which will return the REFCURSOR as an output parameter

CREATE OR REPLACE SP_2 
(
oCurSp2 OUT SYS_REFCURSOR
) AS `enter code here`
BEGIN
/* CALL PROCEDURE SP_1 WITH REF CURSOR AS OUTPUT PARAMETER */
SP_1(oCurSp2);
END SP_2;

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

Well, most other answers here refer to

sort -n

However, I'm not sure this works for negative numbers. Here are the results I get with sort version 6.10 on Fedora 9.

Input file:

-0.907928466796875
-0.61614990234375
1.135406494140625
0.48614501953125
-0.4140167236328125

Output:

-0.4140167236328125
0.48614501953125
-0.61614990234375
-0.907928466796875
1.135406494140625

Which is obviously not ordered by numeric value.

Then, I guess that a more precise answer would be to use sort -n but only if all the values are positive.

P.S.: Using sort -g returns just the same results for this example

Edit:

Looks like the locale settings affect how the minus sign affects the order (see here). In order to get proper results I just did:

LC_ALL=C sort -n filename.txt

I think Gumbo's answer is just fine. Some people prefer this fancy expression that does the same thing:

$int = (($int > 0) ? -$int : $int);

EDIT: Apparently you are looking for a function that will make negatives positive as well. I think these answers are the simplest:

/* I am not proposing you actually use functions called
   "makeNegative" and "makePositive"; I am just presenting
   the most direct solution in the form of two clearly named
   functions. */
function makeNegative($num) { return -abs($num); }
function makePositive($num) { return abs($num); }

If you are brave enough (and have node installed), you can always do something like:

echo "console.log(require('./package.json').version);" | node

This will print the version of the current package. You can also modify it to go insane, like this:

echo "eval('var result='+require('child_process').execSync('npm version',{encoding:'utf8'})); console.log(result.WHATEVER_PACKAGE_NAME);" | node

That will print the version of WHATEVER_PACKAGE_NAME package, that is seen by npm version.

AutoCloseable (introduced in Java 7) makes it possible to use the try-with-resources idiom:

public class MyResource implements AutoCloseable {

    public void close() throws Exception {
        System.out.println("Closing!");
    }

}

Now you can say:

try (MyResource res = new MyResource()) {
    // use resource here
}

and JVM will call close() automatically for you.

Closeable is an older interface. For some reason To preserve backward compatibility, language designers decided to create a separate one. This allows not only all Closeable classes (like streams throwing IOException) to be used in try-with-resources, but also allows throwing more general checked exceptions from close().

When in doubt, use AutoCloseable, users of your class will be grateful.

Arrange them in the order you wants to show. Suppose, you wanna show view 1 on top of view 2. Then write view 2 code then write view 1 code. If you cant does this ordering, then call bringToFront() to the root view of the layout you wants to bring in front.

You can use SET in cmd

To show the current variable, just SET is enough

To show certain variable such as 'PATH', use SET PATH.

For help, type set /?.

For Swift 5

All the above answers are correct but i have done in little different way that is according to device size. Here, in ATFontManager class, i have made default font size which is define at the top of the class as defaultFontSize, this is the font size of iphone plus and you can changed according to your requirement.

class ATFontManager: UIFont{
    
    class func setFont( _ iPhone7PlusFontSize: CGFloat? = nil,andFontName fontN : String = FontName.helveticaNeue) -> UIFont{
        
        let defaultFontSize : CGFloat = 16
        
        switch ATDeviceDetector().screenType {
            
        case .iPhone4:
            if let fontSize = iPhone7PlusFontSize{
                return UIFont(name: fontN, size: fontSize - 5)!
            }
            return UIFont(name: fontN, size: defaultFontSize - 5)!
            
        case .iPhone5:
            if let fontSize = iPhone7PlusFontSize{
                return UIFont(name: fontN, size: fontSize - 3)!
            }
            return UIFont(name: fontN, size: defaultFontSize - 3)!
            
        case .iPhone6AndIphone7, .iPhoneUnknownSmallSize:
            if let fontSize = iPhone7PlusFontSize{
                return UIFont(name: fontN, size: fontSize - 2)!
            }
            return UIFont(name: fontN, size: defaultFontSize - 2)!
            
        case .iPhone6PAndIPhone7P, .iPhoneUnknownBigSize:
            
            return UIFont(name: fontN, size: iPhone7PlusFontSize ?? defaultFontSize)!
        case .iPhoneX, .iPhoneXsMax:
            
            return UIFont(name: fontN, size: iPhone7PlusFontSize ?? defaultFontSize)!
          
        case .iPadMini:
            if let fontSize = iPhone7PlusFontSize{
                return UIFont(name: fontN, size: fontSize + 2)!
            }
            return UIFont(name: fontN, size: defaultFontSize + 2)!
            
        case .iPadPro10Inch:
            if let fontSize = iPhone7PlusFontSize{
                return UIFont(name: fontN, size: fontSize + 4)!
            }
            return UIFont(name: fontN, size: defaultFontSize + 4)!
            
        case .iPadPro:
            if let fontSize = iPhone7PlusFontSize{
                return UIFont(name: fontN, size: fontSize + 6)!
            }
            return UIFont(name: fontN, size: defaultFontSize + 6)!
            
        case .iPadUnknownSmallSize:
            
            return UIFont(name: fontN, size: defaultFontSize + 2)!
            
        case .iPadUnknownBigSize:
            
            return UIFont(name: fontN, size: defaultFontSize + 4)!
            
        default:
            
            return UIFont(name: fontN, size: iPhone7PlusFontSize ?? 16)!
        }
    }
}
     

I have added certain font name, for more you can add the font name and type here.

   enum FontName : String {
        case HelveticaNeue = "HelveticaNeue"
        case HelveticaNeueUltraLight = "HelveticaNeue-UltraLight"
        case HelveticaNeueBold = "HelveticaNeue-Bold"
        case HelveticaNeueBoldItalic = "HelveticaNeue-BoldItalic"
        case HelveticaNeueMedium = "HelveticaNeue-Medium"
        case AvenirBlack = "Avenir-Black"
        case ArialBoldMT = "Arial-BoldMT"
        case HoeflerTextBlack = "HoeflerText-Black"
        case AMCAPEternal = "AMCAPEternal"
    }

This class refers to device detector in order to provide appropriate font size according to device.

class ATDeviceDetector {
    
    var iPhone: Bool {
        
        return UIDevice().userInterfaceIdiom == .phone
    }
    
    var ipad : Bool{
        
        return UIDevice().userInterfaceIdiom == .pad
    }
    
    let isRetina = UIScreen.main.scale >= 2.0
    
    
    enum ScreenType: String {
        
        case iPhone4
        case iPhone5
        case iPhone6AndIphone7
        case iPhone6PAndIPhone7P
        case iPhoneX
        
        case iPadMini
        case iPadPro
        case iPadPro10Inch
        
        case iPhoneOrIPadSmallSizeUnknown
        case iPadUnknown
        case unknown
    }
    
    
    struct ScreenSize{
        
        static let SCREEN_WIDTH         = UIScreen.main.bounds.size.width
        static let SCREEN_HEIGHT        = UIScreen.main.bounds.size.height
        static let SCREEN_MAX_LENGTH    = max(ScreenSize.SCREEN_WIDTH,ScreenSize.SCREEN_HEIGHT)
        static let SCREEN_MIN_LENGTH    = min(ScreenSize.SCREEN_WIDTH,ScreenSize.SCREEN_HEIGHT)
    }
    
    
    var screenType: ScreenType {
        
        switch ScreenSize.SCREEN_MAX_LENGTH {
            
        case 0..<568.0:
            return .iPhone4
        case 568.0:
            return .iPhone5
        case 667.0:
            return .iPhone6AndIphone7
        case 736.0:
            return .iPhone6PAndIPhone7P
        case 812.0:
            return .iPhoneX
        case 568.0..<812.0:
            return .iPhoneOrIPadSmallSizeUnknown
        case 1112.0:
            return .iPadPro10Inch
        case 1024.0:
            return .iPadMini
        case 1366.0:
            return .iPadPro
        case 812.0..<1366.0:
            return .iPadUnknown
        default:
            return .unknown
        }
    }
}

How to use. Hope it will help.

//for default 
label.font = ATFontManager.setFont()

//if you want to provide as your demand. Here **iPhone7PlusFontSize** variable is denoted as font size for *iphone 7plus and iphone 6 plus*, and it **ATFontManager** class automatically handle.
label.font = ATFontManager.setFont(iPhone7PlusFontSize: 15, andFontName: FontName.HelveticaNeue.rawValue)

The problem is because you haven't set JDK version properly.You should use jdk 7 for major number 51. Like this:

JAVA_HOME=/usr/java/jdk1.7.0_79

This solution caters for http, https and the other normal url type special characters :

import re
def remove_urls (vTEXT):
    vTEXT = re.sub(r'(https|http)?:\/\/(\w|\.|\/|\?|\=|\&|\%)*\b', '', vTEXT, flags=re.MULTILINE)
    return(vTEXT)


print( remove_urls("this is a test https://sdfs.sdfsdf.com/sdfsdf/sdfsdf/sd/sdfsdfs?bob=%20tree&jef=man lets see this too https://sdfsdf.fdf.com/sdf/f end"))

one of the answers that exist on the current page (this), is correct but it has some mistakes. for example, it won't work on devices with API 29+. I'll update the above code and post its new version. I think this post should be marked as the final answer.

I am using Laravel 5.5.14 and none of the above worked for me. So here are the steps I did to make it work.

1.Install font-awesome by using npm:

   npm install font-awesome --save

2.Move the fonts to your public directory by adding this line in your webpack.mixin.js

mix.copyDirectory('node_modules/font-awesome/fonts', 'public/fonts/font-awesome');

3.Open your app.scss to specify the path of the fonts in your node_modules and which relative path to use for compilation:

$fa-font-path: "../fonts/font-awesome" !default;
@import "~font-awesome/scss/font-awesome.scss";

All You have to do is git push origin master, where origin is the default name (alias) of Your remote repository and master is the remote branch You want to push Your changes to.

You may also want to check these out:

1. http://gitimmersion.com/
2. http://progit.org/book/

I would avoid now using /// <reference path='moo.ts'/>but for external libraries where the definition file is not included into the package.

The reference path solves errors in the editor, but it does not really means the file needs to be imported. Therefore if you are using a gulp workflow or JSPM, those might try to compile separately each file instead of tsc -out to one file.

From Typescript 1.5

Just prefix what you want to export at the file level (root scope)

aLib.ts

{
export class AClass(){} // exported i.e. will be available for import
export valueZero = 0; // will be available for import
}

You can also add later in the end of the file what you want to export

{
class AClass(){} // not exported yet
valueZero = 0; // not exported yet
valueOne = 1; // not exported (and will not in this example)

export {AClass, valueZero} // pick the one you want to export
}

Or even mix both together

{
class AClass(){} // not exported yet
export valueZero = 0; // will be available for import
export {AClass} // add AClass to the export list
}

For the import you have 2 options, first you pick again what you want (one by one)

anotherFile.ts

{
import {AClass} from "./aLib.ts"; // you import only AClass
var test = new AClass();
}

Or the whole exports

{
import * as lib from "./aLib.ts"; // you import all the exported values within a "lib" object
var test = new lib.AClass();
}

Note regarding the exports: exporting twice the same value will raise an error { export valueZero = 0; export {valueZero}; // valueZero is already exported… }

Just use a two color background image:

<div style="width:100%; background:url('images/bkgmid.png');
       background-size: cover;">
content
</div>

import axios from "axios";
import qs from "qs";   

const url = "https://yourapplicationbaseurl/api/user/authenticate";
    let data = {
      Email: "[email protected]",
      Password: "Admin@123"
    };
    let options = {
      method: "POST",
      headers: { "content-type": "application/x-www-form-urlencoded" },
      data: qs.stringify(data),
      url
    };
    axios(options)
      .then(res => {
        console.log("yeh we have", res.data);
      })
      .catch(er => {
        console.log("no data sorry ", er);
      });
  };

final Map<String, String> mss1 = new ProcessBuilder().environment();
mss1.entrySet()
        .stream()
        //depending on how you want to join K and V use different delimiter
        .map(entry -> 
        String.join(":", entry.getKey(),entry.getValue()))
        .forEach(System.out::println);

Simple (and oversimplified) answer: it's where the jvm stores its own bookkeeping data, as opposed to your data.

You cannot define a variable of an incomplete type. You need to bring the whole definition of Cat into scope before you can create the local variable in main. I recommend that you move the definition of the type Cat to a header and include it from the translation unit that has main.

Because this is a frequent viewed question, I want to mention that a PowerShell function should use approved verbs (Verb-Noun as the function name). The verb part of the name identifies the action that the cmdlet performs. The noun part of the name identifies the entity on which the action is performed. This rule simplifies the usage of your cmdlets for advanced PowerShell users.

Also, you can specify things like whether the parameter is mandatory and the position of the parameter:

function Test-Script
{
    [CmdletBinding()]
    Param
    (
        [Parameter(Mandatory=$true, Position=0)]
        [string]$arg1,

        [Parameter(Mandatory=$true, Position=1)]
        [string]$arg2
    )

    Write-Host "`$arg1 value: $arg1"
    Write-Host "`$arg2 value: $arg2"
}

To pass the parameter to the function you can either use the position:

Test-Script "Hello" "World"

Or you specify the parameter name:

Test-Script -arg1 "Hello" -arg2 "World"

You don't use parentheses like you do when you call a function within C#.

I would recommend to always pass the parameter names when using more than one parameter, since this is more readable.

 protected void Page_Init(object sender, EventArgs e)
 {
   String hostdet = Request.ServerVariables["HTTP_HOST"].ToString();
 }

You can use:

cell.getCellTypeEnum()

Further to compare the cell type, you have to use CellType as follows:-

if(cell.getCellTypeEnum() == CellType.STRING){
      .
      .
      .
}

You can Refer to the documentation. Its pretty helpful:-

https://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Cell.html

You can have only one default export which you declare like:

export default App; or export default class App extends React.Component {...

and later do import App from './App'

If you want to export something more you can use named exports which you declare without default keyword like:

export {
  About,
  Contact,
}

or:

export About;
export Contact;

or:

export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);

and later you import them like:

import App, { About, Contact } from './App';

EDIT:

There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js file. Other than that why export anything if it is no used outside the file?. Correct main.js :

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router'

class App extends React.Component {
...
}

class Home extends React.Component {
...
}


class About extends React.Component {
...
}


class Contact extends React.Component {
...
}


ReactDOM.render((
   <Router history = {browserHistory}>
      <Route path = "/" component = {App}>
         <IndexRoute component = {Home} />
         <Route path = "home" component = {Home} />
         <Route path = "about" component = {About} />
         <Route path = "contact" component = {Contact} />
      </Route>
   </Router>

), document.getElementById('app'))

EDIT2:

another thing is that this tutorial is based on react-router-V3 which has different api than v4.

Lodash has a get method which allows for a default as an optional third parameter, as show below:

const myObject = {_x000D_
  has: 'some',_x000D_
  missing: {_x000D_
    vars: true_x000D_
  }_x000D_
}_x000D_
const path = 'missing.const.value';_x000D_
const myValue = _.get(myObject, path, 'default');_x000D_
console.log(myValue) // prints out default, which is specified above

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.js"></script>

The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:

SELECT *
FROM server1table
    INNER JOIN server2.database.dbo.server2table ON .....

When I had this problem I've done it from command line:

zip file.zip uncompressed

EDIT, after many downvotes: I was using this option for some time ago and I don't know where I learnt it, so I can't give you a better explanation. Chris Johnson's answer is correct, but I won't delete mine. As one comment says, it's more accurate to what OP is asking, as it compress without those files, instead of removing them from a compressed file. I find it easier to remember, too.

You are missing a semicolon at the end of your 'struct' definition.

Also,

*sotrudnik

needs to be

In MySQL, It should be like this

INSERT INTO this_table_archive (col1, col2, ..., coln)
SELECT col1, col2, ..., coln
FROM this_table
WHERE entry_date < '2011-01-01 00:00:00';

MySQL Documentation

I have used this one and it served the purpose:

if($date < date("Y-m-d") ) {
                echo "Date is in the past";}

The following steps can be followed

1) Download Jquery by clicking on this link DOWNLOAD

2) Copy the js file into your root web directory eg. www.test.com/jquery-1.3.2.min.js

3) In your index.php or index.html between the head tags include the following code, and then JQuery will be installed.

<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
