mysql int types can do quite a few rows: http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html

unsigned int largest value is 4,294,967,295
unsigned bigint largest value is 18,446,744,073,709,551,615

One way to cope with the path limit is to shorten path entries with symbolic links.

For example:

1. create a C:\p directory to keep short links to long paths
2. mklink /J C:\p\foo C:\Some\Crazy\Long\Path\foo
3. add C:\p\foo to your path instead of the long path

When dealing with null, = does not match the null values. You can use IS NULL or IS NOT NULL

UPDATE `smartmeter_usage`.`users_reporting` 
SET panel_id = 3 WHERE panel_id IS NULL

LIMIT can be used with UPDATE but with the row count only

The biggest issue I've run into is on a 32-bit system. Once you pass a certain number, tools like 'ls' stop working.

Trying to do anything with that directory once you pass that barrier becomes a huge problem.

Regexes can also limit the number of characters.

r = re.compile("^[a-z]{1,15}$")

gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.

Try run this command it will create a *_limits.conf file under /etc/security/limits.d

echo "* soft nofile 102400" > /etc/security/limits.d/*_limits.conf && echo "* hard nofile 102400" >> /etc/security/limits.d/*_limits.conf

Just exit from terminal and login again and verify by ulimit -n it will set for * users

Why do not you just use CSS to disable the click event. When max files is reached, Dropzone will automatically add a class of dz-max-files-reached.

Use css to disable click on dropzone:

.dz-max-files-reached {
          pointer-events: none;
          cursor: default;
}

Try using head or tail. If you want the 5 most-recently modified files:

ls -1t | head -5

The -1 (that's a one) says one file per line and the head says take the first 5 entries.

If you want the last 5 try

ls -1t | tail -5

Use row_count - your_desired_offset

So if we had 10 rows and want to offset 3

 10 - 3 = 7

Now the query delete from table where this = that order asc limit 7 keeps the last 3, and order desc to keep the first 3:

$row_count - $offset = $limit

Delete from table where entry = criteria order by ts asc limit $limit

A good way is to create a procedure:

create proc pagination (@startfrom int ,@endto int) as
SELECT * FROM ( 
  SELECT *, ROW_NUMBER() OVER (ORDER BY name desc) as row FROM sys.databases 
 ) a WHERE a.row > @startfrom and a.row <= @endto

just like limit 0,2 /////////////// execute pagination 0,4

Theres these available options:-

DB2 has several strategies to cope with this problem.
You can use the "scrollable cursor" in feature.
In this case you can open a cursor and, instead of re-issuing a query you can FETCH forward and backward.
This works great if your application can hold state since it doesn't require DB2 to rerun the query every time.
You can use the ROW_NUMBER() OLAP function to number rows and then return the subset you want.
This is ANSI SQL 
You can use the ROWNUM pseudo columns which does the same as ROW_NUMBER() but is suitable if you have Oracle skills.
You can use LIMIT and OFFSET if you are more leaning to a mySQL or PostgreSQL dialect.  

I thought it has been around a little longer, but according to this,

MySQL 5.7.4 introduces the ability to set server side execution time limits, specified in milliseconds, for top level read-only SELECT statements.

SELECT 
/*+ MAX_EXECUTION_TIME(1000) */ --in milliseconds
* 
FROM table;

Note that this only works for read-only SELECT statements.

Update: This variable was added in MySQL 5.7.4 and renamed to max_execution_time in MySQL 5.7.8. (source)

select top {LIMIT HERE} * from (
      select *, ROW_NUMBER() over (order by {ORDER FIELD}) as r_n_n 
      from {YOUR TABLES} where {OTHER OPTIONAL FILTERS}
) xx where r_n_n >={OFFSET HERE}

A note: This solution will only work in SQL Server 2005 or above, since this was when ROW_NUMBER() was implemented.

In an application I was developing I ran into what appeared to be a POST limit of about 2KB. It turned out to be that I was accidentally encoding the parameters into the URL instead of passing them in the body. So if you're running into a problem there, there is definitely a very small limit on the size of POST data you can send encoded into the URL.

I would try something like this:

SELECT C.*,
      (SELECT P.id, P.title 
       FROM products as P
       WHERE P.category_id = C.id
       LIMIT 1)
FROM categories C

You can use skip and take functions as below:

$products = $art->products->skip($offset*$limit)->take($limit)->get();

// skip should be passed param as integer value to skip the records and starting index

// take gets an integer value to get the no. of records after starting index defined by skip

EDIT

Sorry. I was misunderstood with your question. If you want something like pagination the forPage method will work for you. forPage method works for collections.

REf : https://laravel.com/docs/5.1/collections#method-forpage

e.g

$products = $art->products->forPage($page,$limit);

W3C unequivocally disclaimed this as a myth here

http://www.w3.org/2001/tag/doc/get7#myths

On my blog, the reason of this error is a plugin named Broken Link checker. This plugin has high resource usage from hosting, resulting in this error.

Check if a plugin on your installation is behaving similarly like this.

It looks like that this limitation can be avoided if you use the following URL pattern:

https://googledrive.com/host/file-id

For your case the download URL will look like this - https://googledrive.com/host/0ByvXJAlpPqQPYWNqY0V3MGs0Ujg

Please keep in mind that this method works only if file is shared with "Public on the web" option.

after some test: If you send an email to an outlook client, and the subject is >77 chars, and it needs to use "=?ISO" inside the subject (in my case because of accents) then OutLook will "cut" the subject in the middle of it and mesh it all that comes after, including body text, attaches, etc... all a mesh!

I have several examples like this one:

Subject: =?ISO-8859-1?Q?Actas de la obra N=BA.20100154 (Expediente N=BA.20100182) "NUEVA RED FERROVIARIA.=

TRAMO=20BEASAIN=20OESTE(Pedido=20PC10/00123-125),=20BEASAIN".?=

To:

As you see, in the subject line it cutted on char 78 with a "=" followed by 2 or 3 line feeds, then continued with the rest of the subject baddly.

It was reported to me from several customers who all where using OutLook, other email clients deal with those subjects ok.

If you have no ISO on it, it doesn't hurt, but if you add it to your subject to be nice to RFC, then you get this surprise from OutLook. Bit if you don't add the ISOs, then iPhone email will not understand it(and attach files with names using such characters will not work on iPhones).

A dozen pages is not a big deal when using OFFSET. But when you have hundreds of pages, you will find that OFFSET is bad for performance. This is because all the skipped rows need to be read each time.

It is better to remember where you left off.

Use Remove()...

string foo = "1234567890";
int trimLength = 5;

if (foo.Length > trimLength) foo = foo.Remove(trimLength);

// foo is now "12345"

You could use sp_executesql instead of exec. That allows you to specify an output parameter.

declare @out_var varchar(max);
execute sp_executesql 
    N'select @out_var = ''hello world''', 
    N'@out_var varchar(max) OUTPUT', 
    @out_var = @out_var output;
select @out_var;

This prints "hello world".

This one worked for me:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

My version of mail does not have --append and it too smart for the echo -e \n-trick (it simply replaces \n with space). It does, however, have -a:

mail -a "Content-type: text/html" -s "Built notification" [email protected] < /var/www/report.html

My brute force method to get this to work was just:

1. Dump the table - mysqldump -u user -p database table > dump.sql
2. Find and replace a couple patterns - find /path/to/dump.sql -type f -exec sed -i 's/old_string/new_string/g' {} \;, There are obviously other perl regeular expressions you could perform on the file as well.
3. Import the table - mysqlimport -u user -p database table < dump.sql

If you want to make sure the string isn't elsewhere in your dataset, run a few regular expressions to make sure they all occur in a similar environment. It's also not that tough to create a backup before you run a replace, in case you accidentally destroy something that loses depth of information.

Just a different version of adding a month and subtracting a day for creating reports:

ex: StartofMonth is '2019-10-01'

dateadd(day,-1,dateadd(month,1,StartofMonth))

EndOfMonth will become '2019-10-31'

Delete and Reseed all the tables in a database.

    USE [DatabaseName]
    EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"       -- Disable All the constraints
    EXEC sp_MSForEachTable "DELETE FROM ?"    -- Delete All the Table data
    Exec sp_MSforeachtable 'DBCC CHECKIDENT(''?'', RESEED, 0)' -- Reseed All the table to 0
    Exec sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"  -- Enable All  the constraints back

-- You may ignore the errors that shows the table without Auto increment field.

For structuring an app, this is one of the best guides that I've found:

• Google's Best Practice Recommendations for Angular App Structure

Note that the structure recommended by Google is different than what you'll find in a lot of seed projects, but for large apps it's a lot saner.

Google also has a style guide that makes sense to use only if you also use Closure.

...this answer is incomplete, but I hope that the limited information above will be helpful to someone.

Assuming you want product with MIN()imial value in sort column, it would look something like this.

SELECT 
  c.id, c.title, p.id AS product_id, p.title
FROM 
  categories AS c
INNER JOIN (
  SELECT
    p.id, p.category_id, p.title
  FROM
    products AS p
  CROSS JOIN (
    SELECT p.category_id, MIN(sort) AS sort
    FROM products
    GROUP BY category_id
  ) AS sq USING (category_id)
) AS p ON c.id = p.category_id

In general

Asymptotic notation is something you can understand as: how do functions compare when zooming out? (A good way to test this is simply to use a tool like Desmos and play with your mouse wheel). In particular:

• f(n) ? o(n) means: at some point, the more you zoom out, the more f(n) will be dominated by n (it will progressively diverge from it).
• g(n) ? T(n) means: at some point, zooming out will not change how g(n) compare to n (if we remove ticks from the axis you couldn't tell the zoom level).

Finally h(n) ? O(n) means that function h can be in either of these two categories. It can either look a lot like n or it could be smaller and smaller than n when n increases. Basically, both f(n) and g(n) are also in O(n).

In computer science

In computer science, people will usually prove that a given algorithm admits both an upper O and a lower bound . When both bounds meet that means that we found an asymptotically optimal algorithm to solve that particular problem.

For example, if we prove that the complexity of an algorithm is both in O(n) and (n) it implies that its complexity is in T(n). That's the definition of T and it more or less translates to "asymptotically equal". Which also means that no algorithm can solve the given problem in o(n). Again, roughly saying "this problem can't be solved in less than n steps".

An upper bound of O(n) simply means that even in the worse case, the algorithm will terminate in at most n steps (ignoring all constant factors, both multiplicative and additive). A lower bound of (n) means on the opposite that we built some examples where the problem solved by this algorithm couldn't be solved in less than n steps (again ignoring multiplicative and additive constants). The number of steps is at most n and at least n so this problem complexity is "exactly n". Instead of saying "ignoring constant multiplicative/additive factor" every time we just write T(n) for short.

I also get this issue when i change package name of my application.

In your android studio project find "google-services.json" file. Open it. and check whether package name of your application is same as written in this file.

The package name of your application and package name written in "google-services.json" file must be same.

Promise.allSettled

Instead of Promise.all use Promise.allSettled which waits for all promises to settle, regardless of the result

let p1 = new Promise(resolve => resolve("result1"));
let p2 = new Promise( (resolve,reject) => reject('some troubles') );
let p3 = new Promise(resolve => resolve("result3"));

// It returns info about each promise status and value
Promise.allSettled([p1,p2,p3]).then(result=> console.log(result));

Polyfill

if (!Promise.allSettled) {
  const rejectHandler = reason => ({ status: 'rejected', reason });
  const resolveHandler = value => ({ status: 'fulfilled', value });

  Promise.allSettled = function (promises) {
    const convertedPromises = promises
      .map(p => Promise.resolve(p).then(resolveHandler, rejectHandler));
    return Promise.all(convertedPromises);
  };
}

I opened the file in Notepad++ and did a replacement in a few steps:

1. Replace all "\r\n" with " \r\n"
2. Replace all "; \r\n" with "\r\n"
3. Replace all " \r\n" with " "

This puts all the breaks where they should be and removes those that are breaking up the file.

It worked for me.

What is the difference between <init-param> and <context-param> !?

Single servlet versus multiple servlets.

Other Answers give details, but here is the summary:

A web app, that is, a “context”, is made up of one or more servlets.

• <init-param> defines a value available to a single specific servlet within a context.
• <context-param> defines a value available to all the servlets within a context.

try this

counter = 0

def increment():
  global counter
  counter += 1

increment()

Just a note about setting DefaultCellStyle.BackColor...you can't set it to any transparent value except Color.Empty. That's the default value. That falsely implies (to me, anyway) that transparent colors are OK. They're not. Every row I set to a transparent color just draws the color of selected-rows.

I spent entirely too much time beating my head against the wall over this issue.

By setting you'd use setValue:(id)value forKey:(id)key method of NSMutableDictionary object:

NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setValue:[NSNumber numberWithInt:5] forKey:@"age"];

Or in modern Objective-C:

NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
dict[@"age"] = @5;

The difference between mutable and "normal" is, well, mutability. I.e. you can alter the contents of NSMutableDictionary (and NSMutableArray) while you can't do that with "normal" NSDictionary and NSArray

public static boolean isParsable(String input) {
    try {
        Integer.parseInt(input);
        return true;
    } catch (final NumberFormatException e) {
        return false;
    }
}

Since Spring 2.5 there's a very easy (and elegant) way to achieve that.

You can just change the params proxyMode and value of the @Scope annotation.

With this trick you can avoid to write extra code or to inject the ApplicationContext every time that you need a prototype inside a singleton bean.

Example:

@Service 
@Scope(value="prototype", proxyMode=ScopedProxyMode.TARGET_CLASS)  
public class LoginAction {}

With the config above LoginAction (inside HomeController) is always a prototype even though the controller is a singleton.

I got this exception while coping a object(variable) Matrix Array into Excel sheet. The solution to this is, Matrix array Index(i,j) must start from (0,0) whereas Excel sheet should start with Matrix Array index (i,j) from (1,1) .

I hope you this concept.

I modified my activate script to source the file .virtualenvrc, if it exists in the current directory, and to save/restore PYTHONPATH on activate/deactivate.

You can find the patched activate script here.. It's a drop-in replacement for the activate script created by virtualenv 1.11.6.

Then I added something like this to my .virtualenvrc:

export PYTHONPATH="${PYTHONPATH:+$PYTHONPATH:}/some/library/path"

You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.

function partA() {
  ...
  window.setTimeout(partB,1000);
}

function partB() {
   ...
}

I think because of the below code you are not getting new credential

string fullName = Request.ServerVariables["LOGON_USER"];

You can try custom login page.

I had this problem on production with Heroku and locally while debugging on my macbook pro this morning.

After an hour of debugging, this resolved on its own both locally and on production. I'm not sure what fixed it, so that's a bit annoying. It happened right when I thought I did something, but reverting my supposed fix didn't bring the problem back :(

Interestingly enough, it appears my database service, MongoDb has been having server problems since this morning, so there's a good chance this was related to it.

You can try more reusable my solution with callback function. In this function you can use POST request or some logic. Used libraries: JQuery 3> and Bootstrap 3>.

              /                      
      ---A---B

Where A, B failed commits and W - is revert of M

So before I start fixing found problems I do cherry-pick of W commit to my branch

git cherry-pick -x W

Then I revert W commit on my branch

git revert W 

After I can continue fixing.

The final history could look like:

---o---o---o---M---W---x-------x-------*
              /                       /

When I send a PR it will clearly shows that PR is undo revert and adds some new commits.

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

long and long int are identical. So are long long and long long int. In both cases, the int is optional.

As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long.

The controlling parts of the standard (C++11, but this has been around for a long time) are, for one, 3.9.1 Fundamental types, section 2 (a later section gives similar rules for the unsigned integral types):

There are five standard signed integer types : signed char, short int, int, long int, and long long int. In this list, each type provides at least as much storage as those preceding it in the list.

There's also a table 9 in 7.1.6.2 Simple type specifiers, which shows the "mappings" of the specifiers to actual types (showing that the int is optional), a section of which is shown below:

Specifier(s)         Type
-------------    -------------
long long int    long long int
long long        long long int
long int         long int
long             long int

Note the distinction there between the specifier and the type. The specifier is how you tell the compiler what the type is but you can use different specifiers to end up at the same type.

Hence long on its own is neither a type nor a modifier as your question posits, it's simply a specifier for the long int type. Ditto for long long being a specifier for the long long int type.

Although the C++ standard itself doesn't specify the minimum ranges of integral types, it does cite C99, in 1.2 Normative references, as applying. Hence the minimal ranges as set out in C99 5.2.4.2.1 Sizes of integer types <limits.h> are applicable.

In terms of long double, that's actually a floating point value rather than an integer. Similarly to the integral types, it's required to have at least as much precision as a double and to provide a superset of values over that type (meaning at least those values, not necessarily more values).

git diff --name-only --diff-filter=U | xargs git checkout --theirs

Seems to do the job. Note that you have to be cd'ed to the root directory of the git repo to achieve this.

you can do that by simple way, simply change the variable value that used in for loop to the end value as shown in example

Sub TEST_ONLY()
        For i = 1 To 10
            ActiveSheet.Cells(i, 1).Value = i
            If i = 5 Then
                i = 10
            End If
        Next i
End Sub

If it is a game(may be app also) and you have some static libraries like cocos2d or other third party library ... then you just have to select *ONLY THE* static library (NOT THE APP) and in its build settings under Deployment , set Skip Install flag to YES and Archive it dats it...!!

pep8 was recently added to PyPi.

• pep8 - Python style guide checker
• pep8 is a tool to check your Python code against some of the style conventions in PEP 8.

It is now super easy to check your code against pep8.

See http://pypi.python.org/pypi/pep8

Besides having to escape colons as in the original answer, I have found if the indentation is off you could potentially get the same problem. In one makefile, I had to replace spaces with a tab and that allowed me to get past the error.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Share and enjoy.

You can use append or prepend

The .append() method inserts the specified content as the last child of each element in the jQuery collection (To insert it as the first child, use .prepend()).

$("#tagscloud span").append(second);
$("#tagscloud span").append(third);
$("#tagscloud span").prepend(first);

On one of my sites I had to make a custom search by a lot of data some of it from custom fields here is how my $args look like for one of the options:

$args = array(
    'meta_query' => $meta_query,
    'tax_query' => array(
        $query_tax
    ),
    'posts_per_page' => 10,
    'post_type' => 'ad_listing',
    'orderby' => $orderby,
    'order' => $order,
    'paged' => $paged
);

where "$meta_query" is:

$key = "your_custom_key"; //custom_color for example
$value = "blue";//or red or any color
$query_color = array('key' => $key, 'value' => $value);
$meta_query[] = $query_color;

and after that:

query_posts($args);

so you would probably get more info here: http://codex.wordpress.org/Class_Reference/WP_Query and you can search for "meta_query" in the page to get to the info

I searched for the solution online and found this solution but wasn't too keen on the registry change.

I found a better way: right-click on the solution name right at the top of the Solution Explorer and select the Go Online option. Clicking this allowed me to select the files that had been changed when I was offline and make the solution online again.

After finding the solution, I found the following msdn forum thread which confirmed the above.

bmail. Just install the EXE and run a line like this:

bmail -s myMailServer -f [email protected] -t [email protected] -a "Production Release Performed"

Add an :order parameter to the query

It is due permission problem,

sudo chown -R $USER /path to your python installed directory

default it would be /usr/local/lib/python2.7/

or try,

pip install --user -r package_name

and then say, pip install -r requirements.txt this will install inside your env

dont say, sudo pip install -r requirements.txt this is will install into arbitrary python path.

Updated answer 2020:

There is now a command git sparse-checkout, that I present in detail with Git 2.25 (Q1 2020)

nicono's answer illustrates its usage:

git sparse-checkout init --cone # to fetch only root files
git sparse-checkout add apps/my_app
git sparse-checkout add libs/my_lib

It has evolved with Git 2.27 and knows how to "reapply" a sparse checkout, as in here.
Note that with Git 2.28, git status will mention that you are in a sparse-checked-out repository

Original answer: 2016

git 2.9 (June 2016) will generalize the --no-checkout option to git worktree add (the command which allows to works with multiple working trees for one repo)

See commit ef2a0ac (29 Mar 2016) by Ray Zhang (OneRaynyDay).
Helped-by: Eric Sunshine (sunshineco), and Junio C Hamano (gitster).
^{(Merged by Junio C Hamano -- gitster -- in commit 0d8683c, 13 Apr 2016)}

The git worktree man page now includes:

--[no-]checkout:

By default, add checks out <branch>, however, --no-checkout can be used to suppress checkout in order to make customizations, such as configuring sparse-checkout.

CREATE TABLE `admnih` (
  `id` int(255) NOT NULL auto_increment,
  `asim` varchar(255) NOT NULL default '',
  `brid` varchar(255) NOT NULL default '',
  `rwtbah` int(1) NOT NULL default '0',
  `esmmwkeh` varchar(255) NOT NULL default '',
  `mrwr` varchar(255) NOT NULL default '',
  `tid` int(255) NOT NULL default '0',
  `alksmfialdlil` int(255) NOT NULL default '0',
  `tariktsjil` varchar(255) NOT NULL default '',
  `aimwke` varchar(255) NOT NULL default '',
  `twkie` text NOT NULL,
  `rwtbahkasah` int(255) NOT NULL default '0',
  PRIMARY KEY  (`id`)
) TYPE=MyISAM AUTO_INCREMENT=2 ;

I know this has already been answered, but I stumbled across this question and went down the path of using format, which works, but it returns them as strings when I wanted integers.

I just realized that moment comes with date, month and year methods that return the actual integers for each method.

moment().date()
moment().month()  // jan=0, dec=11
moment().year()

That also resolved my issue.

@ViewChild('map', {static: false}) googleMap;

I don't need to do this very often, the only case I have had was when using Redux Devtools with middleware.

I simply did:

const composeEnhancers = (window as any).__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

Or you could do:

let myWindow = window as any;

and then myWindow.myProp = 'my value';

Here is the typical structure of new Codeigniter project:

- application/
- system/
- user_guide/
- index.php <- this is the file you need to change

I usually use this code in my CI index.php. Just change local_server_name to the name of your local webserver.

With this code you can deploy your site to your production server without changing index.php each time.

// Domain-based environment
if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

/*
 *---------------------------------------------------------------
 * ERROR REPORTING
 *---------------------------------------------------------------
 *
 * Different environments will require different levels of error reporting.
 * By default development will show errors but testing and live will hide them.
 */

if (defined('ENVIRONMENT')) {
    switch (ENVIRONMENT) {
        case 'development':
            error_reporting(E_ALL);
            break;
        case 'testing':
        case 'production':
            error_reporting(0);
            ini_set('display_errors', 0);  
            break;
        default:
            exit('The application environment is not set correctly.');
    }
}

I think you may be confusing Javascript with jQuery methods. Vanilla or plain Javascript is something like:

function example() {
}

A function of that nature can be called at any time, anywhere.

jQuery (a library built on Javascript) has built in functions that generally required the DOM to be fully rendered before being called. The syntax for when this is completed is:

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

So a jQuery function, which is prefixed with the $ or the word jQuery generally is called from within that method.

$(document).ready(function() {        
    // Assign all list items on the page to be the  color red.  
    //      This does not work until AFTER the entire DOM is "ready", hence the $(document).ready()
    $('li').css('color', 'red');   
});

The pseudo-code for that block is:

When the document object model $(document) is ready .ready(), call the following function function() { }. In that function, check for all <li>'s on the page $('li') and using the jQuery method .CSS() to set the CSS property "color" to the value "red" .css('color', 'red');

If, like me, you are running your django in a virtualenv, and getting this error, look at your manage.py. The first line should define the python executable used to run the script. This should be the path to your virtualenv's python, but it is something wrong like /usr/bin/python, which is not the same path and will use the global python environment (and packages will be missing). Just change the path into the path to the python executable in your virtualenv.

You can also replace your shebang line with #!/usr/bin/env python. This should use the proper python environment and interpreter provided that you activate your virtualenv first (I assume you know how to do this).

To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

PHP-FPM is a service that spawns new PHP processes when needed, usually through a fast-cgi module like nginx. You can tell (with a margin of error) by just checking the init.d script e.g. "sudo /etc/init.d/php-fpm status"

What port or unix file socket is being used is up to the configuration, but often is just TCP port 9000. i.e. 127.0.0.1:9000

The best way to tell if it is running correctly is to have nginx running, and setup a virtual host that will fast-cgi pass to PHP-FPM, and just check it with wget or a browser.

Here is how I transitioned from UIWebView to WKWebView.

Note: There is no property like UIWebView that you can drag onto your storyboard, you have to do it programatically.

Make sure you import WebKit/WebKit.h into your header file.

This is my header file:

#import <WebKit/WebKit.h>

@interface ViewController : UIViewController

@property(strong,nonatomic) WKWebView *webView;
@property (strong, nonatomic) NSString *productURL;

@end

Here is my implementation file:

#import "ViewController.h"

@interface ViewController ()

@end


@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.productURL = @"http://www.URL YOU WANT TO VIEW GOES HERE";

    NSURL *url = [NSURL URLWithString:self.productURL];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    _webView = [[WKWebView alloc] initWithFrame:self.view.frame];  
    [_webView loadRequest:request];
    _webView.frame = CGRectMake(self.view.frame.origin.x,self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height);
    [self.view addSubview:_webView];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

 systemctl status nginx.service

You can use as following.

$start_date = date('Y-m-d H:i:s');
$end_date = date("Y-m-d 23:59:59", strtotime('+3 days', strtotime($start_date)));

You can also set days as constant and use like below.

if (!defined('ADD_DAYS')) define('ADD_DAYS','+3 days');
$end_date = date("Y-m-d 23:59:59", strtotime(ADD_DAYS, strtotime($start_date)));

You simply need to enclose your SELECT statements in parentheses to indicate that they are subqueries:

SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);

Alternatively, you can use MySQL's SELECT ... INTO syntax. One advantage of this approach is that both cityLat and cityLng can be assigned from a single table-access:

SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;

However, the entire procedure can be replaced with a single self-joined SELECT statement:

SELECT   b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM     cities AS a, cities AS b
WHERE    a.id = cityID
ORDER BY dist
LIMIT    10;

One hackish way to define an exit method in context:

class Bar; def exit; end; end 

This works because exit in the initializer will be resolved as self.exit¹. In addition, this approach allows using the object after it has been created, as in: b = B.new.

But really, one shouldn't be doing this: don't have exit (or even puts) there to begin with.

(And why is there an "infinite" loop and/or user input in an intiailizer? This entire problem is primarily the result of poorly structured code.)

¹ Remember Kernel#exit is only a method. Since Kernel is included in every Object, then it's merely the case that exit normally resolves to Object#exit. However, this can be changed by introducing an overridden method as shown - nothing fancy.

Here is what you do in Excel 2003:

1. In your sheet of interest, go to Format -> Sheet -> Hide and hide your sheet.
2. Go to Tools -> Protection -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Here is what you do in Excel 2007:

1. In your sheet of interest, go to Home ribbon -> Format -> Hide & Unhide -> Hide Sheet and hide your sheet.
2. Go to Review ribbon -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?

If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.

A socket consists of three things:

1. An IP address
2. A transport protocol
3. A port number

A port is a number between 1 and 65535 inclusive that signifies a logical gate in a device. Every connection between a client and server requires a unique socket.

For example:

• 1030 is a port.
• (10.1.1.2 , TCP , port 1030) is a socket.

As others pointed out, it seems like you can't override nested text-decoration styles... BUT you can change the text-decoration-color.

As a hack, I changed the color to be transparent:

text-decoration-color: transparent;

In my case, I was running tests through MSTest and found out that I was deploying both a 32-bit and 64-bit DLL to the test directory. The program was favoring the 64-bit DLL and causing it to fail.

TL;DR Make sure you only deploy 32-bit DLLs to tests.

You cannot assign arrays, the names are constants that cannot be changed.

You can copy the contents, with:

strcpy(array2, array1);

assuming the source is a valid string and that the destination is large enough, as in your example.

Use Class instead of Interface that is what I discovered after all my research.

Why? A class alone is less code than a class-plus-interface. (anyway you may require a Class for data model)

Why? A class can act as an interface (use implements instead of extends).

Why? An interface-class can be a provider lookup token in Angular dependency injection.

from Angular Style Guide

Basically a Class can do all, what an Interface will do. So may never need to use an Interface.

Date is a container for the number of milliseconds since the Unix epoch ( 00:00:00 UTC on 1 January 1970).

It has no concept of format.

None of the formatting has changed the underlying Date value. This is the purpose of the DateFormatters

Updated with additional example

Just in case the first example didn't make sense...

This example uses two formatters to format the same date. I then use these same formatters to parse the String values back to Dates. The resulting parse does not alter the way Date reports it's value.

Date#toString is just a dump of it's contents. You can't change this, but you can format the Date object any way you like

try {
    Date myDate = new Date();
    System.out.println(myDate);

    SimpleDateFormat mdyFormat = new SimpleDateFormat("MM-dd-yyyy");
    SimpleDateFormat dmyFormat = new SimpleDateFormat("yyyy-MM-dd");

    // Format the date to Strings
    String mdy = mdyFormat.format(myDate);
    String dmy = dmyFormat.format(myDate);

    // Results...
    System.out.println(mdy);
    System.out.println(dmy);
    // Parse the Strings back to dates
    // Note, the formats don't "stick" with the Date value
    System.out.println(mdyFormat.parse(mdy));
    System.out.println(dmyFormat.parse(dmy));
} catch (ParseException exp) {
    exp.printStackTrace();
}

Which outputs...

Also, be careful of the format patterns. Take a closer look at SimpleDateFormat to make sure you're not using the wrong patterns ;)

From MSDN:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

Just add onsubmit event handler for your form:

<form  action="insert.php" onsubmit="return myFunction()" method="post">

Remove onclick from button and make it input with type submit

<input type="submit" value="Submit">

And add boolean return statements to your function:

function myFunction() {
    var pass1 = document.getElementById("pass1").value;
    var pass2 = document.getElementById("pass2").value;
    var ok = true;
    if (pass1 != pass2) {
        //alert("Passwords Do not match");
        document.getElementById("pass1").style.borderColor = "#E34234";
        document.getElementById("pass2").style.borderColor = "#E34234";
        return false;
    }

I think I may have found a simpler way, that nobody mentioned.

A MySQL DATETIME column can be converted to a unix timestamp through:

SELECT unix_timestamp(my_datetime_column) as stamp ...

We can make a new JavaScript Date object by using the constructor that requires milliseconds since the epoch. The unix_timestamp function returns seconds since the epoch, so we need to multiply by 1000:

SELECT unix_timestamp(my_datetime_column) * 1000 as stamp ...

The resulting value can be used directly to instantiate a correct Javascript Date object:

var myDate = new Date(<?=$row['stamp']?>);

Hope this helps.

You might want to have look at simple command line scheduler "at":

C:\Documents and Settings\mahendra.patil>at/?

The AT command schedules commands and programs to run on a computer at a specified time and date. The Schedule service must be running to use the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
    [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\computername Specifies a remote computer. Commands are scheduled on the local computer if this parameter is omitted.

id Is an identification number assigned to a scheduled command.

/delete Cancels a scheduled command. If id is omitted, all the scheduled commands on the computer are canceled.

/yes Used with cancel all jobs command when no further confirmation is desired.

time Specifies the time when command is to run.

/interactive Allows the job to interact with the desktop of the user who is logged on at the time the job runs.

/every:date[,...] Runs the command on each specified day(s) of the week or month. If date is omitted, the current day of the month is assumed.

/next:date[,...] Runs the specified command on the next occurrence of the day (for example, next Thursday). If date is omitted, the current day of the month is assumed.

"command" Is the Windows NT command, or batch program to be run.

Got this problem while transforming my old code from XCode 3x to XCode 4 and Solved it by just renaming wwwwwwww.xib into RootViewController.xib

Swift version - create base64 for image

In my opinion Implicitly Unwrapped Optional in case of UIImagePNGRepresenatation() is not safe, so I recommend to use extension like below:

extension UIImage {

    func toBase64() -> String? {
        let imageData = UIImagePNGRepresentation(self)
        return imageData?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
    }
}

Button button= (Button) findViewById(R.id.standingsButton);
button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        startActivity(new Intent(MainActivity.this,StandingsActivity.class));
    }
});

This code is not in any method. If you want to use it, it must be within a method like OnCreate()

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button button= (Button) findViewById(R.id.standingsButton);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(new Intent(MainActivity.this,StandingsActivity.class));
        }
    });
}

By definition dictionaries are unordered, and therefore cannot be indexed. For that kind of functionality use an ordered dictionary. Python Ordered Dictionary

Spring uses dependency injection to populate the specific value when it finds the @Value annotation. However, instead of handing the value to the instance variable, it's handed to the implicit setter instead. This setter then handles the population of our NAME_STATIC value.

    @RestController 
//or if you want to declare some specific use of the properties file then use
//@Configuration
//@PropertySource({"classpath:application-${youeEnvironment}.properties"})
public class PropertyController {

    @Value("${name}")//not necessary
    private String name;//not necessary

    private static String NAME_STATIC;

    @Value("${name}")
    public void setNameStatic(String name){
        PropertyController.NAME_STATIC = name;
    }
}

SimpleTimer (Swift 3.1)

Why?

This is a simple timer class in swift that enables you to:

• Local scoped timer
• Chainable
• One liners
• Use regular callbacks

Usage:

SimpleTimer(interval: 3,repeats: true){print("tick")}.start()//Ticks every 3 secs

Code:

class SimpleTimer {/*<--was named Timer, but since swift 3, NSTimer is now Timer*/
    typealias Tick = ()->Void
    var timer:Timer?
    var interval:TimeInterval /*in seconds*/
    var repeats:Bool
    var tick:Tick

    init( interval:TimeInterval, repeats:Bool = false, onTick:@escaping Tick){
        self.interval = interval
        self.repeats = repeats
        self.tick = onTick
    }
    func start(){
        timer = Timer.scheduledTimer(timeInterval: interval, target: self, selector: #selector(update), userInfo: nil, repeats: true)//swift 3 upgrade
    }
    func stop(){
        if(timer != nil){timer!.invalidate()}
    }
    /**
     * This method must be in the public or scope
     */
    @objc func update() {
        tick()
    }
}

Should work:

.attr({
    target:"nw", 
    title:"Opens in a new window",
    "data-value":"internal link" // attributes which contain dash(-) should be covered in quotes.
});

Note:

" When setting multiple attributes, the quotes around attribute names are optional.

WARNING: When setting the 'class' attribute, you must always use quotes!

From the jQuery documentation (Sep 2016) for .attr:

Attempting to change the type attribute on an input or button element created via document.createElement() will throw an exception on Internet Explorer 8 or older.

Edit:
For future reference... To get a single attribute you would use

var strAttribute = $(".something").attr("title");

To set a single attribute you would use

$(".something").attr("title","Test");

To set multiple attributes you need to wrap everything in { ... }

$(".something").attr( { title:"Test", alt:"Test2" } );

Edit - If you're trying to get/set the 'checked' attribute from a checkbox...

You will need to use prop() as of jQuery 1.6+

the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

...the most important concept to remember about the checked attribute is that it does not correspond to the checked property. The attribute actually corresponds to the defaultChecked property and should be used only to set the initial value of the checkbox. The checked attribute value does not change with the state of the checkbox, while the checked property does

So to get the checked status of a checkbox, you should use:

$('#checkbox1').prop('checked'); // Returns true/false

Or to set the checkbox as checked or unchecked you should use:

$('#checkbox1').prop('checked', true); // To check it
$('#checkbox1').prop('checked', false); // To uncheck it

It is safe to assume that popular handsets are WVGA800 or bigger. Although, there are a good amount of HVGA screens, they are of secondary concern.

The best defense against leaks is a program structure which minimizes the use of malloc. This is not only good from a programming perspective, but also improves performance and maintainability. I'm not talking about using other things in place of malloc, but in terms of re-using objects and keeping very explicit tabs on all objects being passed around rather than allocating willy-nilly like one often gets used to in languages with garbage collectors like Java.

For example, a program I work on has a bunch of frame objects representing image data. Each frame object has sub-data, which the frame's destructor frees. The program keeps a list of all frames that are allocated, and when it needs a new one, checks a list of unused frame objects to see if it can re-use an existing one rather than allocate a new one. On shutdown, it just iterates through the list, freeing everything.

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

I often use row_number() as a quick way to discard duplicate records from my select statements. Just add a where clause. Something like...

select a,b,rn 
  from (select a, b, row_number() over (partition by a,b order by a,b) as rn           
          from table) 
 where rn=1;

$is_checked = isset($_POST['your_checkbox_name']) &&
              $_POST['your_checkbox_name'] == 'on';

Short circuit evaluation will take care so that you don't access your_checkbox_name when it was not submitted.

What makes jQuery easy to use is that you don't have to apply attributes to each element. The jQuery object contains an array of elements, and the methods of the jQuery object applies the same attributes to all the elements in the array.

There is also a shorter form for $(document).ready(function(){...}) in $(function(){...}).

So, this is all you need:

$(function(){
  $('div.easy_editor').css('border','9px solid red');
});

If you want the code to work for any element with that class, you can just specify the class in the selector without the tag name:

$(function(){
  $('.easy_editor').css('border','9px solid red');
});

A workaround for this problem consists in temporarily changing your regional settings, so the date format of the CSV imported file "matches" the regional settings one.

Open Office seems to work in a similar way for that issue, see: http://www.oooforum.org/forum/viewtopic.phtml?t=85898

I know this is an old question, but I have a solution that isn't listed here.

When you produce the csv add a space after the comma but before your value e.g. , 005,.

This worked to prevent auto date formatting in excel 2007 anyway .

You can create a common volume for all Postgres data

 docker volume create pgdata

or you can set it to the compose file

   version: "3"
   services:
     db:
       image: postgres
       environment:
         - POSTGRES_USER=postgres
         - POSTGRES_PASSWORD=postgress
         - POSTGRES_DB=postgres
       ports:
         - "5433:5432"
       volumes:
         - pgdata:/var/lib/postgresql/data
       networks:
         - suruse
   volumes: 
     pgdata:

It will create volume name pgdata and mount this volume to container's path.

You can inspect this volume

docker volume inspect pgdata

// output will be
[
    {
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/pgdata/_data",
        "Name": "pgdata",
        "Options": {},
        "Scope": "local"
    }
]

$instance->find() returns a reference to a variable.

You get the report when you are trying to use this reference as an argument to a function, without storing it in a variable first.

This helps preventing memory leaks and will probably become an error in the next PHP versions.

Your second code block would throw an error if it wrote like (note the & in the function signature):

function &get_arr(){
    return array(1, 2);
}
$el = array_shift(get_arr());

So a quick (and not so nice) fix would be:

$el = array_shift($tmp = $instance->find(..));

Basically, you do an assignment to a temporary variable first and send the variable as an argument.

Check out the link given it has Apache HTTP Server 2.4.2 x86 and x64 Windows Installers http://www.anindya.com/apache-http-server-2-4-2-x86-and-x64-windows-installers/

This a system error.

Check error of the system with:

tail /var/log/httpd/error_log

It can be any reason.

You most likely have more than one Ruby installed.

If you are using RVM, you probably need to run:

rvm use system

to set the version of ruby to use.

See http://rvm.io/rubies/default

ruby -v

will tell you the version you are currently using.

This is a confusion between constructors and instances.

Remember that when you write a component in React:

class Greeter extends React.Component<any, any> {
    render() {
        return <div>Hello, {this.props.whoToGreet}</div>;
    }
}

You use it this way:

return <Greeter whoToGreet='world' />;

You don't use it this way:

let Greet = new Greeter();
return <Greet whoToGreet='world' />;

In the first example, we're passing around Greeter, the constructor function for our component. That's the correct usage. In the second example, we're passing around an instance of Greeter. That's incorrect, and will fail at runtime with an error like "Object is not a function".

The problem with this code

function renderGreeting(Elem: React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

is that it's expecting an instance of React.Component. What you want is a function that takes a constructor for React.Component:

function renderGreeting(Elem: new() => React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

or similarly:

function renderGreeting(Elem: typeof React.Component) {
    return <span>Hello, <Elem />!</span>;
}

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

What is wrong with using string.Length?

// len will be 5
int len = "Hello".Length;

It is a good practice to set where the access log should be in nginx configuring file . Using acces_log /path/ Like this.

keyval $remote_addr:$http_user_agent $seen zone=clients;

server { listen 443 ssl;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers   HIGH:!aNULL:!MD5;

if ($seen = "") {
    set $seen  1;
    set $logme 1;
}
access_log  /tmp/sslparams.log sslparams if=$logme;
error_log  /pathtolog/error.log;
# ...
}

Great tutorial, fantastic presentation. Neat, simple, short and very explanatory. Although, notification.setLatestEventInfo(this, getText(R.string.service_label), text, contentIntent); method is no more. As trante stated here, good approach would be:

private static final int NOTIFICATION_ID = 45349;

private void showNotification() {
    NotificationCompat.Builder builder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("My Notification Title")
                    .setContentText("Something interesting happened");

    Intent targetIntent = new Intent(this, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, targetIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    _nManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    _nManager.notify(NOTIFICATION_ID, builder.build());
}

@Override
public void onDestroy() {
    super.onDestroy();
    if (_timer != null) {_timer.cancel();}
    _counter=0;
    _nManager.cancel(NOTIFICATION_ID); // Cancel the persistent notification.
    Log.i("PlaybackService", "Service Stopped.");
    _isRunning = false;
}

Checked myself, everything works like a charm (activity and service names may differ from original).

I recommend using Interweave created by milesj. Its a phenomenal library that makes use of a number if ingenious techniques to parse and safely insert HTML into the DOM.

Interweave is a react library to safely render HTML, filter attributes, autowrap text with matchers, render emoji characters, and much more.

• Interweave is a robust React library that can:
  • Safely render HTML without using dangerouslySetInnerHTML.
  • Safely strip HTML tags.
  • Automatic XSS and injection protection.
  • Clean HTML attributes using filters.
  • Interpolate components using matchers.
  • Autolink URLs, IPs, emails, and hashtags.
  • Render Emoji and emoticon characters.
  • And much more!

Usage Example:

import React from 'react';
import { Markup } from 'interweave';

const articleContent = "<p><b>Lorem ipsum dolor laboriosam.</b> </p><p>Facere debitis impedit doloremque eveniet eligendi reiciendis <u>ratione obcaecati repellendus</u> culpa? Blanditiis enim cum tenetur non rem, atque, earum quis, reprehenderit accusantium iure quas beatae.</p><p>Lorem ipsum dolor sit amet <a href='#testLink'>this is a link, click me</a> Sunt ducimus corrupti? Eveniet velit numquam deleniti, delectus  <ol><li>reiciendis ratione obcaecati</li><li>repellendus culpa? Blanditiis enim</li><li>cum tenetur non rem, atque, earum quis,</li></ol>reprehenderit accusantium iure quas beatae.</p>"

<Markup content={articleContent} /> // this will take the articleContent string and convert it to HTML markup. See: https://milesj.gitbook.io/interweave


//to install package using npm, execute the command
npm install interweave

Open I as an array:

>>> I = numpy.asarray(PIL.Image.open('test.jpg'))

Do some stuff to I, then, convert it back to an image:

>>> im = PIL.Image.fromarray(numpy.uint8(I))

Filter numpy images with FFT, Python

If you want to do it explicitly for some reason, there are pil2array() and array2pil() functions using getdata() on this page in correlation.zip.

If the package provides a Makefile.PL - one can use:

perl Makefile.PL PREFIX=/home/my/local/lib LIB=/home/my/local/lib
make
make test
make install

For Eclipse: menu bar-> window -> show view then find "debug" option if not in list then select other ...

new window will open and then search using keyword "debug" -> select debug from list

it will added near console tab. use debug tab to terminate and remove previous executions. ( right clicking on executing process will show you many option including terminate)

So they could be used one day if the language designers felt the need.

Also, if programmers from languages that do have these keywords (eg. C, C++) use them by mistake, then the Java compiler can give a useful error message.

Or maybe it was just to stop programmers using goto :)

Press Ctrl+,

Then you will see a docked window under name of "Go to all"

This a picture of the "Go to all" in my IDE

I'm guessing the reason you're asking is performance? There's the instr function. But that's likely to work pretty much the same behind the scenes.

Maybe you could look into full text search.

As last resorts you'd be looking at caching or precomputed columns/an indexed view.

As an extension to Hiale's solution, you could provide a different or modified version that supports processes that have multiple main windows.

First, amend the structure to allow storing of multiple handles:

struct handle_data {
    unsigned long process_id;
    std::vector<HWND> handles;
};

Second, amend the callback function:

BOOL CALLBACK enum_windows_callback(HWND handle, LPARAM lParam)
{
    handle_data& data = *(handle_data*)lParam;
    unsigned long process_id = 0;
    GetWindowThreadProcessId(handle, &process_id);
    if (data.process_id != process_id || !is_main_window(handle)) {
        return TRUE;
    }
    // change these 2 lines to allow storing of handle and loop again
    data.handles.push_back(handle);
    return TRUE;   
 }

Finally, amend the returns on the main function:

std::vector<HWD> find_main_window(unsigned long process_id)
{
    handle_data data;
    data.process_id = process_id;
    EnumWindows(enum_windows_callback, (LPARAM)&data);
    return data.handles;
}

best bet is targeting features not devices unless you have to, bootstrap do well and you can extend on their breakpoints, for instance targeting pixel density and larger screens above 1920

As @martin and this answer explained, it is complicated. There is no bullet-proof way of getting the client's ip address.

The best that you can do is to try to parse "X-Forwarded-For" and rely on request.getRemoteAddr();

public static String getClientIpAddress(HttpServletRequest request) {
    String xForwardedForHeader = request.getHeader("X-Forwarded-For");
    if (xForwardedForHeader == null) {
        return request.getRemoteAddr();
    } else {
        // As of https://en.wikipedia.org/wiki/X-Forwarded-For
        // The general format of the field is: X-Forwarded-For: client, proxy1, proxy2 ...
        // we only want the client
        return new StringTokenizer(xForwardedForHeader, ",").nextToken().trim();
    }
}

Just Remove the the Workstation Components from Add/Remove Programs - SQL Server 2005. Removing Workstation Components, SQL Server 2008 installation goes well.

From Django 2.0 you can just add a single line in the url.py and change the name.

# url.py

from django.contrib import admin 
admin.site.site_header = "My Admin Central" # Add this

For older versions of Django. (<1.11 and earlier) you need to edit admin/base_site.html

Change this line

{% block title %}{{ title }} | {{ site_title|default:_('Django site admin') }}{% endblock %}

to

{% block title %}{{ title }} | {{ site_title|default:_('Your Site name Admin Central') }}{% endblock %}

You can check your django version by

django-admin --version

GUID is Microsoft's implementation of the UUID standard.

Per Wikipedia:

The term GUID usually refers to Microsoft's implementation of the Universally Unique Identifier (UUID) standard.

An updated quote from that same Wikipedia article:

RFC 4122 itself states that UUIDs "are also known as GUIDs". All this suggests that "GUID", while originally referring to a variant of UUID used by Microsoft, has become simply an alternative name for UUID…

There are MYSQL functions you can use. Like this one that resolves the user:

SELECT USER();

This will return something like root@localhost so you get the host and the user.

To get the current database run this statement:

SELECT DATABASE();

Other useful functions can be found here: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html

Sometimes I want to reset Select2 but I can't without change() method. So my solution is :

function resetSelect2Wrapper(el, value){
    $(el).val(value);
    $(el).select2({
        minimumResultsForSearch: -1,
        language: "fr"
    });
}

Using :

resetSelect2Wrapper("#mySelectId", "myValue");

Try littler. littler provides hash-bang (i.e. script starting with #!/some/path) capability for GNU R, as well as simple command-line and piping use.

Can be done using numpy where() function:

import pandas as pd
import numpy as np

In [716]: df = pd.DataFrame({"gene_name": ['SLC45A1', 'NECAP2', 'CLIC4', 'ADC', 'AGBL4'] , "BoolCol": [False, True, False, True, True] },
       index=list("abcde"))

In [717]: df
Out[717]: 
  BoolCol gene_name
a   False   SLC45A1
b    True    NECAP2
c   False     CLIC4
d    True       ADC
e    True     AGBL4

In [718]: np.where(df["BoolCol"] == True)
Out[718]: (array([1, 3, 4]),)

In [719]: select_indices = list(np.where(df["BoolCol"] == True)[0])

In [720]: df.iloc[select_indices]
Out[720]: 
  BoolCol gene_name
b    True    NECAP2
d    True       ADC
e    True     AGBL4

Though you don't always need index for a match, but incase if you need:

In [796]: df.iloc[select_indices].index
Out[796]: Index([u'b', u'd', u'e'], dtype='object')

In [797]: df.iloc[select_indices].index.tolist()
Out[797]: ['b', 'd', 'e']

The difference between these two methods is:

• parseXxx() returns the primitive type
• valueOf() returns a wrapper object reference of the type.

SELECT t1.* FROM table t1 JOIN table t2 ON t1.Id=t2.Id WHERE t1.C4=t2.C4;

Giving Accurate Result for me.

Activity.runOnUiThread() does not work for me. I worked around this issue by creating a regular thread this way:

public class PullTasksThread extends Thread {
   public void run () {
      Log.d(Prefs.TAG, "Thread run...");
   }
}

and calling it from the GL update this way:

new PullTasksThread().start();

There is an abstraction lib available for PHP. Not sure what your client's box will support but if its Linux then certainly should support building a PHP query interface with this: http://adodb.sourceforge.net/ Hope that helps you.

The SuppressWarning annotation is used to suppress compiler warnings for the annotated element. Specifically, the unchecked category allows suppression of compiler warnings generated as a result of unchecked type casts.

Here is an elegant solution.

There is hidden property for each input element on the form that you can use to determine whether or not the value was changed. Each type of input has it's own property name. For example

• for text/textarea it's defaultValue
• for select it's defaultSelect
• for checkbox/radio it's defaultChecked

Here is the example.

function bindFormChange($form) {

  function touchButtons() {
    var
      changed_objects = [],
      $observable_buttons = $form.find('input[type="submit"], button[type="submit"], button[data-object="reset-form"]');

    changed_objects = $('input:text, input:checkbox, input:radio, textarea, select', $form).map(function () {
      var
        $input = $(this),
        changed = false;

      if ($input.is('input:text') || $input.is('textarea') ) {
        changed = (($input).prop('defaultValue') != $input.val());
      }
      if (!changed && $input.is('select') ) {
        changed = !$('option:selected', $input).prop('defaultSelected');
      }
      if (!changed && $input.is('input:checkbox') || $input.is('input:radio') ) {
        changed = (($input).prop('defaultChecked') != $input.is(':checked'));
      }
      if (changed) {
        return $input.attr('id');
      }

    }).toArray();

    if (changed_objects.length) {
      $observable_buttons.removeAttr('disabled')   
    } else {
      $observable_buttons.attr('disabled', 'disabled');
    }
  };
  touchButtons();

  $('input, textarea, select', $form).each(function () {
    var $input = $(this);

    $input.on('keyup change', function () {
      touchButtons();
    });
  });

};

Now just loop thru the forms on the page and you should see submit buttons disabled by default and they will be activated ONLY if you indeed will change some input value on the form.

$('form').each(function () {
    bindFormChange($(this));
});

Implementation as a jQuery plugin is here https://github.com/kulbida/jmodifiable

  <form>     
            <div class="form-group">
                <label for="nameLabel">Name</label>
                <input id="name" name="name" class="form-control" type="text" /> 
            </div>
            <div class="form-group">
                <label for="PhoneLabel">Phone</label>
                <input id="phone" name="phone" class="form-control" type="text" /> 
            </div>
            <div class="form-group">
                <label for="yearLabel">Year</label>
                <input id="year" name="year" class="form-control" type="text" />
            </div>
        </form>

For this you just need to add content attribute and font-family attribute to the required element via :before or :after wherever applicable.

For example: I wanted to attach an attachment icon after all the a element inside my post. So, first I need to search if such icon exists in fontawesome. Like in the case I found it here, i.e. fa fa-paperclip. Then I would right click the icon there, and go the ::before pseudo property to fetch out the content tag it is using, which in my case I found to be \f0c6. Then I would use that in my css like this:

   .post a:after {
     font-family: FontAwesome,
     content: " \f0c6" /* I added a space before \ for better UI */
    }

In general, an alternative to case when ... is coalesce(nullif(x,bad_value),y) (that cannot be used in OP's case). For example,

select coalesce(nullif(y,''),x), coalesce(nullif(x,''),y), *
from (     (select 'abc' as x, '' as y)
 union all (select 'def' as x, 'ghi' as y)
 union all (select '' as x, 'jkl' as y)
 union all (select null as x, 'mno' as y)
 union all (select 'pqr' as x, null as y)
) q

gives:

 coalesce | coalesce |  x  |  y  
----------+----------+-----+-----
 abc      | abc      | abc | 
 ghi      | def      | def | ghi
 jkl      | jkl      |     | jkl
 mno      | mno      |     | mno
 pqr      | pqr      | pqr | 
(5 rows)

It's also much more better to not modify the app/config/database.php file itself... otherwise modify .env file and put your DB info there. (.env file is available in Laravel 5, not sure if it was there in previous versions...)

NOTE: Of course you should have already set mysql as your default database connection in the app/config/database.php file.

I'm using a UIWebView that isn't a subview (and thus isn't part of the window hierarchy) to determine the sizes of HTML content for UITableViewCells. I found that the disconnected UIWebView doesn't report its size properly with -[UIWebView sizeThatFits:]. Additionally, as mentioned in https://stackoverflow.com/a/3937599/9636, you must set the UIWebView's frame height to 1 in order to get the proper height at all.

If the UIWebView's height is too big (i.e. you have it set to 1000, but the HTML content size is only 500):

UIWebView.scrollView.contentSize.height
-[UIWebView stringByEvaluatingJavaScriptFromString:@"document.height"]
-[UIWebView sizeThatFits:]

All return a height of 1000.

To solve my problem in this case, I used https://stackoverflow.com/a/11770883/9636, which I dutifully voted up. However, I only use this solution when my UIWebView.frame.width is the same as the -[UIWebView sizeThatFits:] width.

This is not a synchronization problem. This will occur if the underlying collection that is being iterated over is modified by anything other than the Iterator itself.

Iterator it = map.entrySet().iterator();
while (it.hasNext())
{
   Entry item = it.next();
   map.remove(item.getKey());
}

This will throw a ConcurrentModificationException when the it.hasNext() is called the second time.

The correct approach would be

   Iterator it = map.entrySet().iterator();
   while (it.hasNext())
   {
      Entry item = it.next();
      it.remove();
   }

Assuming this iterator supports the remove() operation.

I'm adding another answer to this as I had the same problem and solved it the same way: I had installed SSL on apache2 using a2enmod ssl, which seems to have added an extra configuration in /etc/apache2/ports.conf:

NameVirtualHost *:80
Listen 80

NameVirtualHost *:443
Listen 443

<IfModule mod_ssl.c>
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>

I had to comment out the first Listen 443 after the NameVirtualHost *:443 directive:

NameVirtualHost *:443
#Listen 443

But I'm thinking I can as well let it and comment the others. Anyway, thank you for the solution :)

Have you tried plt.tight_layout()?

with plt.tight_layout() without it:

Or: something like this (use add_axes)

left=[0.1,0.3,0.5,0.7]
width=[0.2,0.2, 0.2, 0.2]
rectLS=[]
for x in left:
   for y in left:
       rectLS.append([x, y, 0.2, 0.2])
axLS=[]
fig=plt.figure()
axLS.append(fig.add_axes(rectLS[0]))
for i in [1,2,3]:
     axLS.append(fig.add_axes(rectLS[i],sharey=axLS[-1]))    
axLS.append(fig.add_axes(rectLS[4]))
for i in [1,2,3]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))
axLS.append(fig.add_axes(rectLS[8]))
for i in [5,6,7]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))     
axLS.append(fig.add_axes(rectLS[12]))
for i in [9,10,11]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))

If you don't need to share axes, then simply axLS=map(fig.add_axes, rectLS)

You can use negated character classes to exclude certain characters: for example [^abcde] will match anything but a,b,c,d,e characters.

Instead of specifying all the characters literally, you can use shorthands inside character classes: [\w] (lowercase) will match any "word character" (letter, numbers and underscore), [\W] (uppercase) will match anything but word characters; similarly, [\d] will match the 0-9 digits while [\D] matches anything but the 0-9 digits, and so on.

If you use PHP you can take a look at the regex character classes documentation.

You can use lookups in Ansible in order to get the contents of a file, e.g.

user_data: "{{ lookup('file', user_data_file) }}"

Caveat: This lookup will work with local files, not remote files.

Here's a complete example from the docs:

- hosts: all
  vars:
     contents: "{{ lookup('file', '/etc/foo.txt') }}"
  tasks:
     - debug: msg="the value of foo.txt is {{ contents }}"

You need a spring-security-config.jar on your classpath.

The exception means that the security: xml namescape cannot be handled by spring "parsers". They are implementations of the NamespaceHandler interface, so you need a handler that knows how to process <security: tags. That's the SecurityNamespaceHandler located in spring-security-config

You should always consider what the browser will see by the end. In this case, it will see this:

<img src='something' onmouseover='change(' ex1')' />

In other words, the "onmouseover" attribute is just change(, and there's another "attribute" called ex1')' with no value.

The truth is, HTML does not use \ for an escape character. But it does recognise " and ' as escaped quote and apostrophe, respectively.

Armed with this knowledge, use this:

document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(&quot;ex1&quot;)' />";

... That being said, you could just use JavaScript quotes:

document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(\"ex1\")' />";

Here's what I did:

var timestamp = moment.unix({{ time }});
var utcOffset = moment().utcOffset();
var local_time = timestamp.add(utcOffset, "minutes");
var dateString = local_time.fromNow();

Where {{ time }} is the utc timestamp.

You can use the rpad and lpad functions to pad numbers to the right or to the left, respectively. Note that this does not work directly on numbers, so you'll have to use ::char or ::text to cast them:

SELECT RPAD(numcol::text, 3, '0'), -- Zero-pads to the right up to the length of 3
       LPAD(numcol::text, 3, '0'), -- Zero-pads to the left up to the length of 3
FROM   my_table

If you have PHP & PHP-memcached installed, you can run

$ php -r '$c = new Memcached(); $c->addServer("localhost", 11211); var_dump( $c->getAllKeys() );'

Rather than placing an extra scanner.nextLine() each time you want to read something, since it seems you want to accept each input on a new line, you might want to instead changing the delimiter to actually match only newlines (instead of any whitespace, as is the default)

import java.util.Scanner;

class ScannerTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        scanner.useDelimiter("\\n");

        System.out.print("Enter an index: ");
        int index = scanner.nextInt();

        System.out.print("Enter a sentence: ");
        String sentence = scanner.next();

        System.out.println("\nYour sentence: " + sentence);
        System.out.println("Your index: " + index);
    }
}

Thus, to read a line of input, you only need scanner.next() that has the same behavior delimiter-wise of next{Int, Double, ...}

The difference with the "nextLine() every time" approach, is that the latter will accept, as an index also <space>3, 3<space> and 3<space>whatever while the former only accepts 3 on a line on its own

a = np.arange(18).reshape(9,2)
b = a.reshape(3,3,2).swapaxes(0,2)

# a: 
array([[ 0,  1],
       [ 2,  3],
       [ 4,  5],
       [ 6,  7],
       [ 8,  9],
       [10, 11],
       [12, 13],
       [14, 15],
       [16, 17]])


# b:
array([[[ 0,  6, 12],
        [ 2,  8, 14],
        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

I also followed Josh Frankel's advice and created a Sublime Macro + added key binding. The difference is that this script ensures that spacing is first set to tabs and set to a tab size of 2. The macro won't work if that's not the starting point.

Here's a gist of the macro: https://gist.github.com/drivelous/aa8dc907de34efa3e462c65a96e05f09

In Mac, to use the macro + key binding:

1. Create a file called spaces2to4.sublime-macro and copy/paste the code from the gist. For me this is located at:

/Library/Application\ Support/Sublime\ Text\ 3/Packages/User/spaces2to4.sublime-macro

2. Select Sublime Text > Preferences > Key Bindings
3. Add this command to the User specified sublime-keymap (it's in an array -- it may be empty):

{
    "keys": ["super+shift+o"],
    "command": "run_macro_file",
    "args": {
        "file":"Packages/User/spaces2to4.sublime-macro"
    }
}

Now ? + shift + o now automatically converts each file from 2 space indentation to 4 (but will keep indenting if you run it further)

This will work, but the i -> i is doing some automatic unboxing which is why it "feels" strange. Either of the following will work and better explain what the compiler is doing under the hood with your original syntax:

integers.values().stream().mapToInt(i -> i.intValue()).sum();
integers.values().stream().mapToInt(Integer::intValue).sum();

If you have to display the field on report header then try this... RightClick on Textbox > Properties > Category > date > select *Format (Note this will maintain the regional settings).

Since this question has been viewed many times, I'm posting it... Hope it helps.

Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.

The configuration and the access to the Connection string looks all right to me. I would always add a providername

<connectionStrings>
  <add name="Dbconnection" 
       connectionString="Server=localhost; Database=OnlineShopping; 
       Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

If you set CURLOPT_RETURNTRANSFER to true or 1 then the return value from curl_exec will be the actual result from the successful operation. In other words it will not return TRUE on success. Although it will return FALSE on failure.

As described in the Return Values section of curl-exec PHP manual page: http://php.net/manual/function.curl-exec.php

You should enable the CURLOPT_FOLLOWLOCATION option for redirects but this would be a problem if your server is in safe_mode and/or open_basedir is in effect which can cause issues with curl as well.

MacOS uses /usr/libexec/java_home to find the current Java Version. One way to bypass is to change the plist file as explained by @void256 above. Other ways is to take the backup of the java_home and replace it with your own script java_home having the code
echo $JAVA_HOME

Now export the JAVA_HOME to the desired version of the SDK by adding the following commands to the ~/.bash_profile. export JAVA_HOME="/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home" launchctl setenv JAVA_HOME $JAVA_HOME /// Make the environment variable global

Run the command source ~/.bash_profile to the run the above commands.

Anytime one needs to change the JAVA_HOME he can reset the JAVA_HOME value in the ~/.bash_profile file.

To find all local IPv4 addresses:

IPAddress[] ipv4Addresses = Array.FindAll(
    Dns.GetHostEntry(string.Empty).AddressList,
    a => a.AddressFamily == AddressFamily.InterNetwork);

or use Array.Find or Array.FindLast if you just want one.

I've found the best method is to write your default CSS for the older browsers, as older browsers including i.e. 5.5, 6, 7 and 8. Can't read @media. When I use @media I use it like this:

<style type="text/css">
    /* default styles here for older browsers. 
       I tend to go for a 600px - 960px width max but using percentages
    */
    @media only screen and (min-width: 960px) {
        /* styles for browsers larger than 960px; */
    }
    @media only screen and (min-width: 1440px) {
        /* styles for browsers larger than 1440px; */
    }
    @media only screen and (min-width: 2000px) {
        /* for sumo sized (mac) screens */
    }
    @media only screen and (max-device-width: 480px) {
       /* styles for mobile browsers smaller than 480px; (iPhone) */
    }
    @media only screen and (device-width: 768px) {
       /* default iPad screens */
    }
    /* different techniques for iPad screening */
    @media only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait) {
      /* For portrait layouts only */
    }

    @media only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:landscape) {
      /* For landscape layouts only */
    }
</style>

But you can do whatever you like with your @media, This is just an example of what I've found best for me when building styles for all browsers.

iPad CSS specifications.

Also! If you're looking for printability you can use @media print{}

You can also replace without a regular expression.

while(str.indexOf('  ')!=-1)str.replace('  ',' ');

You could use the stopifnot() function if you want the program to produce an error:

foo <- function(x) {
    stopifnot(x > 500)
    # rest of program
}

Auth::user()->products->sum('price');

The documentation is a little light for some of the Collection methods but all the query builder aggregates are seemingly available besides avg() that can be found at http://laravel.com/docs/queries#aggregates.

Actualy you don't need an internet connection to use ip address. Each computer in LAN has an internal IP address you can discover by runing

ipconfig /all

in cmd.

You can use the ip address of the server (probabily something like 192.168.0.x or 10.0.0.x) to access the website remotely.

If you found the ip and still cannot access the website, it means WAMP is not configured to respond to that name ( what did you call me? 192.168.0.3? That's not my name. I'm Localhost ) and you have to modify ....../apache/config/httpd.conf

Listen *:80

The problem here is that in your code the program is calling 'null.length()' which is not defined if the argument passed to the function is null. That's why the exception is thrown.

I agree with the other answers that using two containers is preferable, but if you have your heart set on bunding multiple services in a single container you can use something like supervisord.

in Hipache for instance, the included Dockerfile runs supervisord, and the file supervisord.conf specifies for both hipache and redis-server to be run.

I had this same problem on Ubuntu 19.10 LTS.

To solve this I ran the following command:

$ sudo apt install node-typescript

After that, I was able to use tsc.

No need to convert it in a string by using json.dumps()

r = {'is_claimed': 'True', 'rating': 3.5}
file.write(r['is_claimed'])
file.write(str(r['rating']))

You can get the values directly from the dict object.

It is possible, just overwrite the Recaptcha Ajax callbacks. Working jsfiddle: http://jsfiddle.net/Vanit/Qu6kn/

You don't even need a proxy div because with the overwrites the DOM code won't execute. Call Recaptcha.reload() whenever you want to trigger the callbacks again.

function doSomething(challenge){
    $(':input[name=recaptcha_challenge_field]').val(challenge);
    $('img.recaptcha').attr('src', '//www.google.com/recaptcha/api/image?c='+challenge);
}

//Called on Recaptcha.reload()
Recaptcha.finish_reload = function(challenge,b,c){
    doSomething(challenge);
}

//Called on page load
Recaptcha.challenge_callback = function(){
    doSomething(RecaptchaState.challenge)
}

Recaptcha.create("YOUR_PUBLIC_KEY");

The following example creates a file chooser and displays it as first an open-file dialog and then as a save-file dialog:

String filename = File.separator+"tmp";
JFileChooser fc = new JFileChooser(new File(filename));

// Show open dialog; this method does not return until the dialog is closed
fc.showOpenDialog(frame);
File selFile = fc.getSelectedFile();

// Show save dialog; this method does not return until the dialog is closed
fc.showSaveDialog(frame);
selFile = fc.getSelectedFile();

Here is a more elaborate example that creates two buttons that create and show file chooser dialogs.

// This action creates and shows a modal open-file dialog.
public class OpenFileAction extends AbstractAction {
    JFrame frame;
    JFileChooser chooser;

    OpenFileAction(JFrame frame, JFileChooser chooser) {
        super("Open...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showOpenDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

// This action creates and shows a modal save-file dialog.
public class SaveFileAction extends AbstractAction {
    JFileChooser chooser;
    JFrame frame;

    SaveFileAction(JFrame frame, JFileChooser chooser) {
        super("Save As...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showSaveDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

FormsAuthentication.Decrypt takes the actual value of the cookie, not the name of it. You can get the cookie value like

HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName].Value;

and decrypt that.

If you have TensorFlow 2.x:

sess = tf.compat.v1.Session(config=tf.compat.v1.ConfigProto(log_device_placement=True))

We use this code to center the Bootstrap modal dialogs when they open. I haven't had any issue with them on iOS while using this but I'm not sure if it will work for Android.

$('.modal').on('show', function(e) {
    var modal = $(this);
    modal.css('margin-top', (modal.outerHeight() / 2) * -1)
         .css('margin-left', (modal.outerWidth() / 2) * -1);
    return this;
});

No Answer is true

The true Answer is Edit Column to NVARCHAR and you found Automatically trim Execute but this code UPDATE Table SET Name = RTRIM(LTRIM(Name)) use it only with Nvarchar if use it with CHAR or NCHAR it will not work

The latest version of elementtree supports XPath pretty well. Not being an XPath expert I can't say for sure if the implementation is full but it has satisfied most of my needs when working in Python. I've also use lxml and PyXML and I find etree nice because it's a standard module.

NOTE: I've since found lxml and for me it's definitely the best XML lib out there for Python. It does XPath nicely as well (though again perhaps not a full implementation).

On my case, just to be safe regarding scrolling, I added the window.scroll to the equation:

var element = document.getElementById('myElement');
var topPos = element.getBoundingClientRect().top + window.scrollY;
var leftPos = element.getBoundingClientRect().left + window.scrollX;

That allows me to get the real relative position of element on document, even if it has been scrolled.

use

Objective-C

[headingButton setTitleColor:[UIColor colorWithRed:36/255.0 green:71/255.0 blue:113/255.0 alpha:1.0] forState:UIControlStateNormal];

Swift

headingButton.setTitleColor(.black, for: .normal)

Lot of people including myself face lot of issues in making this work due to missing some information like, forgetting to convert to Base64, initialization vectors, character set, etc. So I thought of making a fully functional code.

Hope this will be useful to you all: To compile you need additional Apache Commons Codec jar, which is available here: http://commons.apache.org/proper/commons-codec/download_codec.cgi

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

import org.apache.commons.codec.binary.Base64;

public class Encryptor {
    public static String encrypt(String key, String initVector, String value) {
        try {
            IvParameterSpec iv = new IvParameterSpec(initVector.getBytes("UTF-8"));
            SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");

            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);

            byte[] encrypted = cipher.doFinal(value.getBytes());
            System.out.println("encrypted string: "
                    + Base64.encodeBase64String(encrypted));

            return Base64.encodeBase64String(encrypted);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

        return null;
    }

    public static String decrypt(String key, String initVector, String encrypted) {
        try {
            IvParameterSpec iv = new IvParameterSpec(initVector.getBytes("UTF-8"));
            SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");

            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
            cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);

            byte[] original = cipher.doFinal(Base64.decodeBase64(encrypted));

            return new String(original);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

        return null;
    }

    public static void main(String[] args) {
        String key = "Bar12345Bar12345"; // 128 bit key
        String initVector = "RandomInitVector"; // 16 bytes IV

        System.out.println(decrypt(key, initVector,
                encrypt(key, initVector, "Hello World")));
    }
}

When using JUnit asserts, I always make the message nice and clear. It saves huge amounts of time debugging. Doing it this way avoids having to add a added dependency on hamcrest Matchers.

previousTokenValues[1] = "1378994409108";
currentTokenValues[1] = "1378994416509";

Long prev = Long.parseLong(previousTokenValues[1]);
Long curr = Long.parseLong(currentTokenValues[1]);
assertTrue("Previous (" + prev + ") should be greater than current (" + curr + ")", prev > curr);

Okay, the easiest way, I found out was just changing the url (jsfiddle[dot]net) to fiddle[dot]jshell[dot]net/ There u have a clear html code, without any kind of iframe... Example: https://jsfiddle[dot]net/mfvmoy64/27/show/light/ -> http://fiddle[dot]jshell[dot]net/mfvmoy64/27/show/light/

(Must change the '.''s to "[dot]" because of stackeroverflow... :c) PS: sry 4 bad english

You can use Hibernate Dialect API for Database independence as follow

class SequenceValueGetter {
    private SessionFactory sessionFactory;

    // For Hibernate 3
    public Long getId(final String sequenceName) {
        final List<Long> ids = new ArrayList<Long>(1);

        sessionFactory.getCurrentSession().doWork(new Work() {
            public void execute(Connection connection) throws SQLException {
                DialectResolver dialectResolver = new StandardDialectResolver();
                Dialect dialect =  dialectResolver.resolveDialect(connection.getMetaData());
                PreparedStatement preparedStatement = null;
                ResultSet resultSet = null;
                try {
                    preparedStatement = connection.prepareStatement( dialect.getSequenceNextValString(sequenceName));
                    resultSet = preparedStatement.executeQuery();
                    resultSet.next();
                    ids.add(resultSet.getLong(1));
                }catch (SQLException e) {
                    throw e;
                } finally {
                    if(preparedStatement != null) {
                        preparedStatement.close();
                    }
                    if(resultSet != null) {
                        resultSet.close();
                    }
                }
            }
        });
        return ids.get(0);
    }

    // For Hibernate 4
    public Long getID(final String sequenceName) {
        ReturningWork<Long> maxReturningWork = new ReturningWork<Long>() {
            @Override
            public Long execute(Connection connection) throws SQLException {
                DialectResolver dialectResolver = new StandardDialectResolver();
                Dialect dialect =  dialectResolver.resolveDialect(connection.getMetaData());
                PreparedStatement preparedStatement = null;
                ResultSet resultSet = null;
                try {
                    preparedStatement = connection.prepareStatement( dialect.getSequenceNextValString(sequenceName));
                    resultSet = preparedStatement.executeQuery();
                    resultSet.next();
                    return resultSet.getLong(1);
                }catch (SQLException e) {
                    throw e;
                } finally {
                    if(preparedStatement != null) {
                        preparedStatement.close();
                    }
                    if(resultSet != null) {
                        resultSet.close();
                    }
                }

            }
        };
        Long maxRecord = sessionFactory.getCurrentSession().doReturningWork(maxReturningWork);
        return maxRecord;
    }

}

For 32 bit it will return 32 and for 64 bit it will return 64

import struct
print(struct.calcsize("P") * 8)

There seems to be a lot of these questions surrounding inheriting a member method from a Grandparent Class, overriding it in a second Class, then calling its method again from a Grandchild Class. Why not just inherit the grandparent's members down to the grandchildren?

class A
{
    private string mystring = "A";    
    public string Method1()
    {
        return mystring;
    }
}

class B : A
{
    // this inherits Method1() naturally
}

class C : B
{
    // this inherits Method1() naturally
}


string newstring = "";
A a = new A();
B b = new B();
C c = new C();
newstring = a.Method1();// returns "A"
newstring = b.Method1();// returns "A"
newstring = c.Method1();// returns "A"

Seems simple....the grandchild inherits the grandparents method here. Think about it.....that's how "Object" and its members like ToString() are inherited down to all classes in C#. I'm thinking Microsoft has not done a good job of explaining basic inheritance. There is too much focus on polymorphism and implementation. When I dig through their documentation there are no examples of this very basic idea. :(

If that's literally all you want to do then just declaring the array as string fixes the selected item problem:

myViewData.PageOptionsDropDown = 
   new SelectList(new string[] {"10", "15", "25", "50", "100", "1000"}, "15");

I solved my problem with this commands:

cat __mydomain_com.crt __mydomain_com.ca-bundle > __mydomain_com_combine.crt

and after:

cat __mydomain_com_combine.crt COMODORSADomainValidationSecureServerCA.crt 
COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > mydomain.pem

And in my domain nginx .conf I put on the server 443:

ssl_certificate          ssl/mydomain.pem;
ssl_certificate_key      ssl/mydomain.private.key;

I don't forget restart your "Nginx"

service nginx restart

Since no answers were posted, I found the following here:

The Web server (running the Web site) thinks that the request submitted by the client (e.g. your Web browser or our CheckUpDown robot) can not be completed because it conflicts with some rule already established. For example, you may get a 409 error if you try to upload a file to the Web server which is older than the one already there - resulting in a version control conflict.

Someone on a similar question right here on stackoverflow, said the answer was:

I've had this issue when I was referencing the url of the document library and not the destination file itself.

i.e. try http://server name/document library name/new file name.doc

However I am 100% sure this was not my case, since I checked the WebRequest's URI property several times and the URI was complete with filename, and all the folders in the path existed on the sharepoint site.

Anyways, I hope this helps someone.

If you want to add multiple files in a given folder you can split them using {,}. This is awesome for not repeating long paths, e.g.

git add long/path/{file1,file2,...,filen}

Beware not to put spaces between the ,.

A possible solution is:

java.awt.EventQueue.invokeLater(new Runnable() {
    @Override
    public void run() {
        myFrame.toFront();
        myFrame.repaint();
    }
});

in jquery-3.1.1

$("#id").load(function(){_x000D_
//code goes here});

will not work because load function is no more work

This problem is caused (as others have stated) by model attributes being persisted into the query string - this is usually undesirable and is at risk of creating security holes as well as ridiculous query strings. My usual solution is to never use Strings for redirects in Spring MVC, instead use a RedirectView which can be configured not to expose model attributes (see: http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/web/servlet/view/RedirectView.html)

RedirectView(String url, boolean contextRelative, boolean http10Compatible, boolean exposeModelAttributes)

So I tend to have a util method which does a 'safe redirect' like:

public static RedirectView safeRedirect(String url) {
    RedirectView rv = new RedirectView(url);
    rv.setExposeModelAttributes(false);
    return rv;
}

The other option is to use bean configuration XML:

<bean id="myBean" class="org.springframework.web.servlet.view.RedirectView">
   <property name="exposeModelAttributes" value="false" />
   <property name="url" value="/myRedirect"/>
</bean>

Again, you could abstract this into its own class to avoid repetition (e.g. SafeRedirectView).

A note about 'clearing the model' - this is not the same as 'not exposing the model' in all circumstances. One site I worked on had a lot of filters which added things to the model, this meant that clearing the model before redirecting would not prevent a long query string. I would also suggest that 'not exposing model attributes' is a more semantic approach than 'clearing the model before redirecting'.

There are several ways to do it, through settings or by deleting the cache.

Deleting the cache is the most versatile method. First, locate it:

On XP, it was located here:

C:\Documents and Settings\%USER%\Application Data\Subversion\auth\svn.simple\

On Vista, it was located here:

C:\Users\%USER%\AppData\Roaming\Subversion\auth\svn.simple\

Then look in those files with Notepad, and delete the one with your credentials.

When you want the super class constructor to be called - to initialize the fields within it. Take a look at this article for an understanding of when to use it:

Though this doesn't answer your question exactly, here's one way to generate every permutation of the letters from a number of strings of the same length: eg, if your words were "coffee", "joomla" and "moodle", you can expect output like "coodle", "joodee", "joffle", etc.

Basically, the number of combinations is the (number of words) to the power of (number of letters per word). So, choose a random number between 0 and the number of combinations - 1, convert that number to base (number of words), then use each digit of that number as the indicator for which word to take the next letter from.

eg: in the above example. 3 words, 6 letters = 729 combinations. Choose a random number: 465. Convert to base 3: 122020. Take the first letter from word 1, 2nd from word 2, 3rd from word 2, 4th from word 0... and you get... "joofle".

If you wanted all the permutations, just loop from 0 to 728. Of course, if you're just choosing one random value, a much simpler less-confusing way would be to loop over the letters. This method lets you avoid recursion, should you want all the permutations, plus it makes you look like you know Maths^(tm)!

If the number of combinations is excessive, you can break it up into a series of smaller words and concatenate them at the end.

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

Have you considered letting the user of your application select their own color scheme? Without fail you won't be able to please all of your users with your selection but you can allow them to find what pleases them.

'JavaType' works !! I was trying to unmarshall (deserialize) a List in json String to ArrayList java Objects and was struggling to find a solution since days.
Below is the code that finally gave me solution. Code:

JsonMarshallerUnmarshaller<T> {
    T targetClass;

    public ArrayList<T> unmarshal(String jsonString) {
        ObjectMapper mapper = new ObjectMapper();

        AnnotationIntrospector introspector = new JacksonAnnotationIntrospector();
        mapper.getDeserializationConfig()
            .withAnnotationIntrospector(introspector);

        mapper.getSerializationConfig()
            .withAnnotationIntrospector(introspector);
        JavaType type = mapper.getTypeFactory().
            constructCollectionType(
                ArrayList.class, 
                targetclass.getClass());

        try {
            Class c1 = this.targetclass.getClass();
            Class c2 = this.targetclass1.getClass();
            ArrayList<T> temp = (ArrayList<T>) 
                mapper.readValue(jsonString,  type);
            return temp ;
        } catch (JsonParseException e) {
            e.printStackTrace();
        } catch (JsonMappingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null ;
    }  
}

I faced this problem when using a static page (e.g. index.html) as the start up page - Application-Start does not get called. I discovered that serving a static page does not actually start the application. Requesting an .aspx page does.

I liked the bubble sort extension method approach on "Richie"'s blog above, but I don't necessarily want to just sort comparing the entire object. I more often want to sort on a specific property of the object. So I modified it to accept a key selector the way OrderBy does so you can choose which property to sort on:

    public static void Sort<TSource, TKey>(this ObservableCollection<TSource> source, Func<TSource, TKey> keySelector)
    {
        if (source == null) return;

        Comparer<TKey> comparer = Comparer<TKey>.Default;

        for (int i = source.Count - 1; i >= 0; i--)
        {
            for (int j = 1; j <= i; j++)
            {
                TSource o1 = source[j - 1];
                TSource o2 = source[j];
                if (comparer.Compare(keySelector(o1), keySelector(o2)) > 0)
                {
                    source.Remove(o1);
                    source.Insert(j, o1);
                }
            }
        }
    }

Which you would call the same way you would call OrderBy except it will sort the existing instance of your ObservableCollection instead of returning a new collection:

ObservableCollection<Person> people = new ObservableCollection<Person>();
...

people.Sort(p => p.FirstName);

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

Instead of downloading curl, down libcurl.

The log indicates that mongodb is terminating because there is an old lock file.

If you are not and were not running with journaling, remove the lock file, run repair, and start mongodb again.

If you are or were running with journaling turned on, see the relevant Mongo DB docs. Note that they say "If you are running with Journaling you should not do a repair to recover to a consistent state." So if you were journaling, the repair may have made things worse.

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

I tried all previously mentioned answers, but in my case I had to manually specify the include path of the iostream file. As I use MinGW the path was:

C:\MinGW\lib\gcc\mingw32\4.8.1\include\c++

You can add the path in Eclipse under: Project > C/C++ General > Paths and Symbols > Includes > Add. I hope that helps

If you have already installed nvm then execute the following commands

• nvm deactivate - This will remove /.nvm/*/bin from $PATH
• nvm list - To list out all the versions of node installed in the system
• nvm uninstall <version> in you can specify all the versions you want to uninstall.

It is always a good that you install node using nvm and uninstall using nvm rather than brew .

This solution worked for me.

Additional Commands

• which node to know the path of node installed in your system. You can rm this directory to uninstall node manually. Then you may need to adjust the PATH file accordingly.

If logical test is against a single column then you could use something like

USE AdventureWorks2012;

      CASE ProductLine  
         WHEN 'R' THEN 'Road'  
         WHEN 'M' THEN 'Mountain'  
         WHEN 'T' THEN 'Touring'  
         WHEN 'S' THEN 'Other sale items'  
         ELSE 'Not for sale'  
      END,  
   Name  
FROM Production.Product  
ORDER BY ProductNumber;  
GO

I'd like to suggest another way to maintain python session through tmux on linux. you run tmux, attach your self to the session you opened (if not attached after opening it directly). execute python and do whatever you are doing on it. then detach from session. detaching from a tmux session does not close the session. the session remains open.

pros of this method: you can attach to this session from any other device (in case you can ssh your pc)

cons of this method: this method does not relinquish the resources used by the opened python session until you actually exist the python interpreter.

I just made a getter method.

public int getNumberRows(){
    try{
       statement = connection.creatStatement();
       resultset = statement.executeQuery("your query here");
       if(resultset.last()){
          return resultset.getRow();
       } else {
           return 0; //just cus I like to always do some kinda else statement.
       }
    } catch (Exception e){
       System.out.println("Error getting row count");
       e.printStackTrace();
    }
    return 0;
}

Just pick the columns you want directly....

df[['A','E','I','C']]

reserve when you do not want the objects to be initialized when reserved. also, you may prefer to logically differentiate and track its count versus its use count when you resize. so there is a behavioral difference in the interface - the vector will represent the same number of elements when reserved, and will be 100 elements larger when resized in your scenario.

Is there any better choice in this kind of scenario?

it depends entirely on your aims when fighting the default behavior. some people will favor customized allocators -- but we really need a better idea of what it is you are attempting to solve in your program to advise you well.

fwiw, many vector implementations will simply double the allocated element count when they must grow - are you trying to minimize peak allocation sizes or are you trying to reserve enough space for some lock free program or something else?

Rab's answer works great, but not for Microsoft Edge, so I added a small adaptation for Edge as well:

https://jsfiddle.net/et9borp4/

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    // Microsoft Edge
    else if(window.navigator.userAgent.indexOf("Edge") > -1) {
      var startPos = myField.selectionStart; 
      var endPos = myField.selectionEnd; 

      myField.value = myField.value.substring(0, startPos)+ myValue 
             + myField.value.substring(endPos, myField.value.length); 

      var pos = startPos + myValue.length;
      myField.focus();
      myField.setSelectionRange(pos, pos);
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

An alternative to NCover can be PartCover, is an open source code coverage tool for .NET very similar to NCover, it includes a console application, a GUI coverage browser, and XSL transforms for use in CruiseControl.NET.

It is a very interesting product.

OpenCover has replaced PartCover.

There is another way. If you're passing an object by reference, that object's properties will appear in the function's local scope. I know this works for Safari (haven't checked other browsers) and I don't know if this feature has a name, but the below example illustrates its use.

Although in practice I don't think that this offers any functional value beyond the technique you're already using, it's a little cleaner semantically. And it still requires passing a object reference or an object literal.

function sum({ a:a, b:b}) {
    console.log(a+'+'+b);
    if(a==undefined) a=0;
    if(b==undefined) b=0;
    return (a+b);
}

// will work (returns 9 and 3 respectively)
console.log(sum({a:4,b:5}));
console.log(sum({a:3}));

// will not work (returns 0)
console.log(sum(4,5));
console.log(sum(4));
