Don't abuse private fields get/set by reflection

Using reflection as that is done in several answers here is something that we could avoid.
It brings a small value here while it presents multiple drawbacks :

• we detect reflection issues only at runtime (ex: fields not existing any longer)
• We want encapsulation but not a opaque class that hides dependencies that should be visible and make the class more opaque and less testable.
• it encourages bad design. Today you declare a @Value String field. Tomorrow you can declare 5 or 10 of them in that class and you may not even be straight aware that you decrease the design of the class. With a more visible approach to set these fields (such as constructor) , you will think twice before adding all these fields and you will probably encapsulate them into another class and use @ConfigurationProperties.

Make your class testable both unitary and in integration

To be able to write both plain unit tests (that is without a running spring container) and integration tests for your Spring component class, you have to make this class usable with or without Spring.
Running a container in an unit test when it is not required is a bad practice that slows down local builds : you don't want that.
I added this answer because no answer here seems to show this distinction and so they rely on a running container systematically.

So I think that you should move this property defined as an internal of the class :

@Component
public class Foo{   
    @Value("${property.value}") private String property;
    //...
}

into a constructor parameter that will be injected by Spring :

@Component
public class Foo{   
    private String property;
     
    public Foo(@Value("${property.value}") String property){
       this.property = property;
    }

    //...         
}

Unit test example

You can instantiate Foo without Spring and inject any value for property thanks to the constructor :

public class FooTest{

   Foo foo = new Foo("dummyValue");

   @Test
   public void doThat(){
      ...
   }
}

Integration test example

You can injecting the property in the context with Spring Boot in this simple way thanks to the properties attribute of @SpringBootTest :

@SpringBootTest(properties="property.value=dummyValue")
public class FooTest{
    
   @Autowired
   Foo foo;
     
   @Test
   public void doThat(){
       ...
   }    
}

You could use as alternative @TestPropertySource but it adds an additional annotation :

@SpringBootTest
@TestPropertySource(properties="property.value=dummyValue")
public class FooTest{ ...}

With Spring (without Spring Boot), it should be a little more complicated but as I didn't use Spring without Spring Boot from a long time I don't prefer say a stupid thing.

As a side note : if you have many @Value fields to set, extracting them into a class annotated with @ConfigurationProperties is more relevant because we don't want a constructor with too many arguments.

Take look at my code. It makes the font size smaller to fit whatever there.

But I think this doesn't lead to a good user experience

var containerWidth = $("#ui-id-2").width();
var items = $(".quickSearchAutocomplete .ui-menu-item");
var fontSize = 16;

items.each(function(){
    // Displaying a value depends sometimes on your case. You may make it block or inline-table instead of inline-block or whatever value that make the div take overflow width.
    $(this).css({"whiteSpace": "nowrap", "display": "inline-block"});
    while ($(this).width() > containerWidth){
         console.log("$(this).width()" + $(this).width() + "containerWidth" + containerWidth)
         $(this).css("font-size", fontSize -= 0.5);
    }
});

As the dictionary documentation for python 2 and python 3 would tell you, in python 2 items returns a list, while iteritems returns a iterator.

In python 3, items returns a view, which is pretty much the same as an iterator.

If you are using python 2, you may want to user iteritems if you are dealing with large dictionaries and all you want to do is iterate over the items (not necessarily copy them to a list)

wt = tt - cpu tm.
Tt = cpu tm + wt.

Where wt is a waiting time and tt is turnaround time. Cpu time is also called burst time.

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

Is the recommendation to include CSS before JavaScript invalid?

Not if you treat it as simply a recommendation. But if your treat it as a hard and fast rule?, yes, it is invalid.

From https://developer.mozilla.org/en-US/docs/Web/Reference/Events/DOMContentLoaded

Stylesheet loads block script execution, so if you have a <script> after a <link rel="stylesheet" ...> the page will not finish parsing - and DOMContentLoaded will not fire - until the stylesheet is loaded.

It appears that you need to know what each script relies on and make sure that execution of the script is delayed until after the right completion event. If the script relies only on the DOM, it can resume in ondomready/domcontentloaded, if it relies on images to be loaded or stylesheets to be applied, then if I read the above reference correctly, that code must be deferred until the onload event.

I don't think that one sock size fits all, even though that is the way they are sold and I know that one shoe size does not fit all. I don't think that there is a definitive answer to which to load first, styles or script. It is more a case by case decision of what must be loaded in what order and what can be deferred until later as not being on the "critical path".

To speak to the observer that commented that it is better to delay the users ability to interact until the sheet is pretty. There are many of you out there and you annoy your counterparts that feel the opposite. They came to a site to accomplish a purpose and delays to their ability to interact with a site while waiting for things that don't matter to finish loading are very frustrating. I am not saying that you are wrong, only that you should be aware that there is another faction that exists that does not share your priority.

This question particularly applies to all of the ads being placed on web sites. I would love it if site authors rendered just placeholder divs for the ad content and made sure that their site was loaded and interactive before injecting the ads in an onload event. Even then I would like to see the ads loaded serially instead of all at once because they impact my ability to even scroll the site content while the bloated ads are loading. But that is just one persons point of view.

• Know your users and what they value.
• Know your users and what browsing environment they use.
• Know what each file does, and what its pre-requisites are. Making everything work will take precedence over both speed and pretty.
• Use tools that show you the network time line when developing.
• Test in each of the environments that your users use. It may be needed to dynamically (server side, when creating the page) alter the order of loading based on the users environment.
• When in doubt, alter the order and measure again.
• It is possible that intermixing styles and scripts in the load order will be optimal; not all of one then all of the other.
• Experiment not just what order to load the files but where. Head? In Body? After Body? DOM Ready/Loaded? Loaded?
• Consider async and defer options when appropriate to reduce the net delay the user will experience before being able to interact with the page. Test to determine if they help or hurt.
• There will always be trade offs to consider when evaluating the optimal load order. Pretty vs. Responsive being just one.

The reason why the naive solution doesn't work is that it gives a higher probability density to the points closer to the circle center. In other words the circle that has radius r/2 has probability r/2 of getting a point selected in it, but it has area (number of points) pi*r^2/4.

Therefore we want a radius probability density to have the following property:

The probability of choosing a radius smaller or equal to a given r has to be proportional to the area of the circle with radius r. (because we want to have a uniform distribution on the points and larger areas mean more points)

In other words we want the probability of choosing a radius between [0,r] to be equal to its share of the overall area of the circle. The total circle area is pi*R^2, and the area of the circle with radius r is pi*r^2. Thus we would like the probability of choosing a radius between [0,r] to be (pi*r^2)/(pi*R^2) = r^2/R^2.

Now comes the math:

The probability of choosing a radius between [0,r] is the integral of p(r) dr from 0 to r (that's just because we add all the probabilities of the smaller radii). Thus we want integral(p(r)dr) = r^2/R^2. We can clearly see that R^2 is a constant, so all we need to do is figure out which p(r), when integrated would give us something like r^2. The answer is clearly r * constant. integral(r * constant dr) = r^2/2 * constant. This has to be equal to r^2/R^2, therefore constant = 2/R^2. Thus you have the probability distribution p(r) = r * 2/R^2

Note: Another more intuitive way to think about the problem is to imagine that you are trying to give each circle of radius r a probability density equal to the proportion of the number of points it has on its circumference. Thus a circle which has radius r will have 2 * pi * r "points" on its circumference. The total number of points is pi * R^2. Thus you should give the circle r a probability equal to (2 * pi * r) / (pi * R^2) = 2 * r/R^2. This is much easier to understand and more intuitive, but it's not quite as mathematically sound.

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

def Method(self, atributes..)

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

There are two problems:

1. Integer is pass by value, not by reference. Changing the reference inside a method won't be reflected into the passed-in reference in the calling method.
2. Integer is immutable. There's no such method like Integer#set(i). You could otherwise just make use of it.

To get it to work, you need to reassign the return value of the inc() method.

integer = inc(integer);

To learn a bit more about passing by value, here's another example:

public static void main(String... args) {
    String[] strings = new String[] { "foo", "bar" };
    changeReference(strings);
    System.out.println(Arrays.toString(strings)); // still [foo, bar]
    changeValue(strings);
    System.out.println(Arrays.toString(strings)); // [foo, foo]
}
public static void changeReference(String[] strings) {
    strings = new String[] { "foo", "foo" };
}
public static void changeValue(String[] strings) {
    strings[1] = "foo";
}

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

Including use strict in the beginning of your all sensitive JavaScript files from this point is a small way to be a better JavaScript programmer and avoid random variables becoming global and things change silently.

Workarounds are not solutions, therefore the answer is "No".

Still looking for workarounds, here are possible solutions: http://support.code42.com/CrashPlan/Latest/Troubleshooting/Windows_File_Paths_Longer_Than_255_Characters

<?php
$start = microtime(true);
for ($i = 0; $i < 10000000; $i++) {
    $a = 'a';
    $a = NULL;
}
$elapsed = microtime(true) - $start;

echo "took $elapsed seconds\r\n";



$start = microtime(true);
for ($i = 0; $i < 10000000; $i++) {
    $a = 'a';
    unset($a);
}
$elapsed = microtime(true) - $start;

echo "took $elapsed seconds\r\n";
?>

Per that it seems like "= null" is faster.

Things start to look different with PHP 5.0 and 4.4.

4.4:

• took 7.5352551937103 seconds
• took 6.6245851516724 seconds

Keep in mind microtime(true) doesn't work in PHP 4.4 so I had to use the microtime_float example given in php.net/microtime / Example #1.

In my workflow, I rebase as much as possible (and I try to do it often. Not letting the discrepancies accumulate drastically reduces the amount and the severity of collisions between branches).

However, even in a mostly rebase-based workflow, there is a place for merges.

Recall that merge actually creates a node that has two parents. Now consider the following situation: I have two independent feature brances A and B, and now want to develop stuff on feature branch C which depends on both A and B, while A and B are getting reviewed.

What I do then, is the following:

1. Create (and checkout) branch C on top of A.
2. Merge it with B

Now branch C includes changes from both A and B, and I can continue developing on it. If I do any change to A, then I reconstruct the graph of branches in the following way:

1. create branch T on the new top of A
2. merge T with B
3. rebase C onto T
4. delete branch T

This way I can actually maintain arbitrary graphs of branches, but doing something more complex than the situation described above is already too complex, given that there is no automatic tool to do the rebasing when the parent changes.

Programming is so easy a five year old can do it.

Programming in and of itself is not hard, it's common sense. You are just telling a computer what to do. You're not a genius, please get over yourself.

It is easy to assign repeated values to an array:

x(1:10) = 5;

If you want to generate the array of elements inline in a statement try something like this:

ones(1,10) * 5

or with repmat

repmat(5, 1, 10)

HTML :

<div id="myDiv">
    <form id="myForm">
    </form> 
</div>

jQuery :

var chbx='<input type="checkbox" id="Mumbai" name="Mumbai" value="Mumbai" />Mumbai<br /> <input type="checkbox" id=" Delhi" name=" Delhi" value=" Delhi" /> Delhi<br/><input type="checkbox" id=" Bangalore" name=" Bangalore" value=" Bangalore"/>Bangalore<br />';

$("#myDiv form#myForm").html(chbx);

//to insert dynamically created form 
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");

Demo

If the "default value" you want is immutable, @eduffy's suggestion, e.g. [0]*10, is good enough.

But if you want, say, a list of ten dicts, do not use [{}]*10 -- that would give you a list with the same initially-empty dict ten times, not ten distinct ones. Rather, use [{} for i in range(10)] or similar constructs, to construct ten separate dicts to make up your list.

even better, this will measure the average of n iterations of your query! Great for a more accurate reading.

declare @tTOTAL int = 0
declare @i integer = 0
declare @itrs integer = 100

while @i < @itrs
begin
declare @t0 datetime = GETDATE()

--your query here

declare @t1 datetime = GETDATE()

set @tTotal = @tTotal + DATEDIFF(MICROSECOND,@t0,@t1)

set @i = @i + 1
end

select @tTotal/@itrs

Ideally, the Python script you want to run will be set up with code like this near the end:

def main(arg1, arg2, etc):
    # do whatever the script does


if __name__ == "__main__":
    main(sys.argv[1], sys.argv[2], sys.argv[3])

In other words, if the module is called from the command line, it parses the command line options and then calls another function, main(), to do the actual work. (The actual arguments will vary, and the parsing may be more involved.)

If you want to call such a script from another Python script, however, you can simply import it and call modulename.main() directly, rather than going through the operating system.

os.system will work, but it is the roundabout (read "slow") way to do it, as you are starting a whole new Python interpreter process each time for no raisin.

$date = strtotime("+1 day");
echo date('m-d-y',$date);

Select first the text you want to format and then press Ctrl+I.

Use Cmd+A first if you wish to format all text in the selected file.

Note: this procedure only re-indents the lines, it does not do any advanced formatting.

The new key binding to re-indent is control+I.

cURL-less you can use in php5

$url = 'URL';
$data = array('field1' => 'value', 'field2' => 'value');
$options = array(
        'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data),
    )
);

$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);

you can achive this by calling a function also

<div [style.width.px]="getCustomeWidth()"></div>

  getCustomeWidth() {
    //do what ever you want here
    return customeWidth;
  }

You can use sp_lock (and sp_lock2), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks:

select  
    object_name(p.object_id) as TableName, 
    resource_type, resource_description
from
    sys.dm_tran_locks l
    join sys.partitions p on l.resource_associated_entity_id = p.hobt_id

in my case it was a cross-origin frame and wasn't loading sometimes. the solution that worked for me is: if it's loaded successfully then if you try this code:

var iframe = document.getElementsByTagName('iframe')[0];
console.log(iframe.contentDocument);

it won't allow you to access contentDocument and throw a cross-origin error however if frame is not loaded successfully then contentDocument will return a #document object

I met the error: "The transaction log for database '...' is full due to 'ACTIVE_TRANSACTION' while deleting old rows from tables of my database for freeing disk space. I realized that this error would occur if the number of rows to be deleted was bigger than 1000000 in my case. So instead of using 1 DELETE statement, i divided the delete task by using DELETE TOP (1000000).... statement.

For example:

instead of using this statement:

DELETE FROM Vt30 WHERE Rt < DATEADD(YEAR, -1, GETDATE())

using following statement repeatedly:

DELETE TOP(1000000) FROM Vt30 WHERE Rt < DATEADD(YEAR, -1, GETDATE())

If the Facebook application is logged in, the page will be opened when executing the following code. If the Facebook application is not logged in when executing the code, the user will then be redirected to the Facebook app to login and then after connecting the Facebook is not redirected to the page!

Go to project properties -> Project Facets. Make sure the Dynamic Web Module and Java is checked.

Apart from it, "Cloud Foundry Standalone Application" needs to be un-checked, if it is already selected. By default, few IDEs preselect this option.

For my case, the culprit was the semicolon and double quotes in the password for prod DB. Our IT team use some tool to generate passwords, so it generated one with the semicolon and double quotes Connectionstring looks like

Got the password changed and it worked.

Not all parameters are supported by all cameras - actually, they are one of the most troublesome part of the OpenCV library. Each camera type - from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of them, but of course not all possibilities are covered.

What you can do is to investigate your camera driver, write a patch for OpenCV and send it to code.opencv.org. This way others will enjoy your work, the same way you enjoy others'.

There is also a possibility that your camera does not support your request - most USB cams are cheap and simple. Maybe that parameter is just not available for modifications.

If you are sure the camera supports a given param (you say the camera manufacturer provides some code) and do not want to mess with OpenCV, you can wrap that sample code in C++ with boost::python, to make it available in Python. Then, enjoy using it.

You don't really have to call the __init__ methods of the base class(es), but you usually want to do it because the base classes will do some important initializations there that are needed for rest of the classes methods to work.

For other methods it depends on your intentions. If you just want to add something to the base classes behavior you will want to call the base classes method additionally to your own code. If you want to fundamentally change the behavior, you might not call the base class' method and implement all the functionality directly in the derived class.

cURL is an option, using Ajax as well eventhough solving back-end problems with the front-end isn't so neat.

A very useful post about doing it without cURL is this one: http://netevil.org/blog/2006/nov/http-post-from-php-without-curl

The code to do this (untested, unimproved, from the blog post):

function do_post_request($url, $data, $optional_headers = null)
{
   $params = array('http' => array(
                'method' => 'POST',
                'content' => $data
             ));
   if ($optional_headers !== null) {
      $params['http']['header'] = $optional_headers;
   }
   $ctx = stream_context_create($params);
   $fp = @fopen($url, 'rb', false, $ctx);
   if (!$fp) {
      throw new Exception("Problem with $url, $php_errormsg");
   }
   $response = @stream_get_contents($fp);
   if ($response === false) {
      throw new Exception("Problem reading data from $url, $php_errormsg");
   }
   return $response;
}

Subscribing what basil said in a comment to the question itself, if method = RequestMethod.GET you can use @RequestParam List<String> groupVal.

Then calling the service with the list of params is as simple as:

API_URL?groupVal=kkk,ccc,mmm

This code worked for me

The following works for me... S3 objects:

s3://bucket/
    form1/
       section11/
          file111
          file112
       section12/
          file121
    form2/
       section21/
          file211
          file112
       section22/
          file221
          file222
          ...
      ...
   ...

Using:

from boto3.session import Session
s3client = session.client('s3')
resp = s3client.list_objects(Bucket=bucket, Prefix='', Delimiter="/")
forms = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/
form2/
...

With:

resp = s3client.list_objects(Bucket=bucket, Prefix='form1/', Delimiter="/")
sections = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/section11/
form1/section12/

You don't appear to have write permission to the /tmp directory on your server. This is a bit weird, but you can work around it. Before the call to session_start() put in a call to session_save_path() and give it the name of a directory writable by the server. Details are here.

you must have gcc,json_pure

i collect some information from several post

sudo gem uninstall sass_x000D_

Hi if ** sudo gem update --system ** not working you got an error in the update then use

sudo gem update --system 2.7.8

To explain where other answers haven't; the problem is your use of keypress.

Perhaps the event is just mis-named but keypress is defined to fire when when an actualcharacteris being inserted. I.e. text.
Whereas what you want is keydown/keyup, which fires whenever (before or after, respectively) the user depresses akey. I.e. those things on the keyboard.

The difference appears here because esc is a control character (literally 'non-printing character') and so doesn't write any text, thus not even firing keypress.
enter is weird, because even though you are using it as a control character (i.e. to control the UI), it is still inserting a new-line character, which will fire keypress.

I run this

var data = '{"rut" : "' + $('#cb_rut').val() + '" , "email" : "' + $('#email').val() + '" }';
var data = JSON.parse(data);

$.ajax({
    type: 'GET',
    url: 'linkserverApi',
    success: function(success) {
        console.log('Success!');
        console.log(success);
    },
    error: function() {
        console.log('Uh Oh!');
    },
    jsonp: 'jsonp'

});

And edit header in the response

'Access-Control-Allow-Methods' , 'GET, POST, PUT, DELETE'

'Access-Control-Max-Age' , '3628800'

'Access-Control-Allow-Origin', 'websiteresponseUrl'

'Content-Type', 'text/javascript; charset=utf8'

jQuery has already implemented promises, so it's better to use this technology and not move events logic to options parameter. I made a jQuery plugin that adds progress promise and now it's easy to use just as other promises:

$.ajax(url)
  .progress(function(){
    /* do some actions */
  })
  .progressUpload(function(){
    /* do something on uploading */
  });

To get utf8-encoded file as opposed to ascii-encoded in the accepted answer for Python 2 use:

import io, json
with io.open('data.txt', 'w', encoding='utf-8') as f:
  f.write(json.dumps(data, ensure_ascii=False))

The code is simpler in Python 3:

import json
with open('data.txt', 'w') as f:
  json.dump(data, f, ensure_ascii=False)

On Windows, the encoding='utf-8' argument to open is still necessary.

To avoid storing an encoded copy of the data in memory (result of dumps) and to output utf8-encoded bytestrings in both Python 2 and 3, use:

import json, codecs
with open('data.txt', 'wb') as f:
    json.dump(data, codecs.getwriter('utf-8')(f), ensure_ascii=False)

The codecs.getwriter call is redundant in Python 3 but required for Python 2

Readability and size:

The use of ensure_ascii=False gives better readability and smaller size:

>>> json.dumps({'price': '€10'})
'{"price": "\\u20ac10"}'
>>> json.dumps({'price': '€10'}, ensure_ascii=False)
'{"price": "€10"}'

>>> len(json.dumps({'?????': 1}))
37
>>> len(json.dumps({'?????': 1}, ensure_ascii=False).encode('utf8'))
17

Further improve readability by adding flags indent=4, sort_keys=True (as suggested by dinos66) to arguments of dump or dumps. This way you'll get a nicely indented sorted structure in the json file at the cost of a slightly larger file size.

To get started with LaTeX on Linux, you're going to need to install a couple of packages:

1. You're going to need a LaTeX distribution. This is the collection of programs that comprise the (La)TeX computer typesetting system. The standard LaTeX distribution on Unix systems used to be teTeX, but it has been superceded by TeX Live. Most Linux distributions have installation packages for TeX Live--see, for example, the package database entries for Ubuntu and Fedora.

2. You will probably want to install a LaTeX editor. Standard Linux text editors will work fine; in particular, Emacs has a nice package of (La)TeX editing macros called AUCTeX. Specialized LaTeX editors also exist; of those, Kile (KDE Integrated LaTeX Environment) is particularly nice.

3. You will probably want a LaTeX tutorial. The classic tutorial is "A (Not So) Short Introduction to LaTeX2e," but nowadays the LaTeX wikibook might be a better choice.

Because of low reputation, I cannot comment the accepted answer.

I would like to mention the predefined variable CPPFLAGS. It might represent a better fit than CFLAGS or CXXFLAGS, since it is described by the GNU Make manual as:

Extra flags to give to the C preprocessor and programs that use it (the C and Fortran compilers).

Examples of built-in implicit rules that use CPPFLAGS

• n.o is made automatically from n.c with a recipe of the form:
  • $(CC) $(CPPFLAGS) $(CFLAGS) -c
• n.o is made automatically from n.cc, n.cpp, or n.C with a recipe of the form:
  • $(CXX) $(CPPFLAGS) $(CXXFLAGS) -c

One would use the command make CPPFLAGS=-Dvar=123 to define the desired macro.

I encountered the same problem after freshly installing git on Windows 10 and running it for the first time. Restarting the bash window solved the problem.

I made a lexer/tokenizer before with the use of only standard libraries. Here's the code:

#include <iostream>
#include <string>
#include <vector>
#include <sstream>

using namespace std;

string seps(string& s) {
    if (!s.size()) return "";
    stringstream ss;
    ss << s[0];
    for (int i = 1; i < s.size(); i++) {
        ss << '|' << s[i];
    }
    return ss.str();
}

void Tokenize(string& str, vector<string>& tokens, const string& delimiters = " ")
{
    seps(str);

    // Skip delimiters at beginning.
    string::size_type lastPos = str.find_first_not_of(delimiters, 0);
    // Find first "non-delimiter".
    string::size_type pos = str.find_first_of(delimiters, lastPos);

    while (string::npos != pos || string::npos != lastPos)
    {
        // Found a token, add it to the vector.
        tokens.push_back(str.substr(lastPos, pos - lastPos));
        // Skip delimiters.  Note the "not_of"
        lastPos = str.find_first_not_of(delimiters, pos);
        // Find next "non-delimiter"
        pos = str.find_first_of(delimiters, lastPos);
    }
}

int main(int argc, char *argv[])
{
    vector<string> t;
    string s = "Tokens for everyone!";

    Tokenize(s, t, "|");

    for (auto c : t)
        cout << c << endl;

    system("pause");

    return 0;
}

In my case, I did this

  const eventId = event.id;
  User.findByIdAndUpdate(id, { $push: { createdEvents: eventId } }).exec();

Option 3

To update current iframe

$("iframe").wrap('<div class="embed-responsive embed-responsive-16by9"/>');
$("iframe").addClass('embed-responsive-item');

If you look at your XAMPP Control Panel, it's clearly stated that the port to the MySQL server is 3306 - you provided 3360. The 3306 is default, and thus doesn't need to be specified. Even so, the 5th parameter of mysqli_connect() is the port, which is where it should be specified.

You could just remove the port specification altogether, as you're using the default port, making it

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db     = 'test_db13';

In my case it was the file size restriction which was put on proxy server. Zip file of gradle was not able to download due this restriction. I was getting 401 error while downloading gradle zip file. If you are getting 401 or 403 error in log, make sure you are able to download those files manually.

Well try ini_set('memory_limit', '256M');

134217728 bytes = 128 MB

Or rewrite the code to consume less memory.

When compare something with Boolean it works like following

Step 1: Convert boolean to Number Number(true) // 1 and Number(false) // 0

Step 2: Compare both sides

boolean == someting 
-> Number(boolean) === someting

If compare 1 and 2 with true you will get the following results

true == 1
-> Number(true) === 1
-> 1 === 1
-> true

And

true == 2
-> Number(true) === 1
-> 1 === 2
-> false

\s means "one space", and \s+ means "one or more spaces".

But, because you're using the /g flag (replace all occurrences) and replacing with the empty string, your two expressions have the same effect.

There's actually a very little known class in the BCL for this purpose exactly: CommaDelimitedStringCollectionConverter. It serves as a middle ground of sorts between having a ConfigurationElementCollection (as in Richard's answer) and parsing the string yourself (as in Adam's answer).

For example, you could write the following configuration section:

public class MySection : ConfigurationSection
{
    [ConfigurationProperty("MyStrings")]
    [TypeConverter(typeof(CommaDelimitedStringCollectionConverter))]
    public CommaDelimitedStringCollection MyStrings
    {
        get { return (CommaDelimitedStringCollection)base["MyStrings"]; }
    }
}

You could then have an app.config that looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="foo" type="ConsoleApplication1.MySection, ConsoleApplication1"/>
  </configSections>
  <foo MyStrings="a,b,c,hello,world"/>
</configuration>

Finally, your code would look like this:

var section = (MySection)ConfigurationManager.GetSection("foo");
foreach (var s in section.MyStrings)
    Console.WriteLine(s); //for example

Right-click on the column header and select Format Cells, the chose Date and select the desired date format. Those that are not recognized are ambiguous, and as such not interpreted as anything but that is resolved after applying formatting to the column. Note that for me, in Excel 2002 SP3, the dates given above are automatically and correctly interpreted as dates when pasting.

In my case I'm doing it like this:

 module SayHi {
    export default () => { console.log("Hi"); }
 }
 new SayHi();

Jonathan is correct. PHP arrays act as a map table mapping keys to values. in some cases you can get an index if your array is defined, such as

$var = array(2,5);

for ($i = 0; $i < count($var); $i++) {
    echo $var[$i]."\n";
}

your output will be

2
5

in which case each element in the array has a knowable index, but if you then do something like the following

$var = array_push($var,10);

for ($i = 0; $i < count($var); $i++) {
    echo $var[$i]."\n";
}

you get no output. This happens because arrays in PHP are not linear structures like they are in most languages. They are more like hash tables that may or may not have keys for all stored values. Hence foreach doesn't use indexes to crawl over them because they only have an index if the array is defined. If you need to have an index, make sure your arrays are fully defined before crawling over them, and use a for loop.

You may go with Plotly library. It can render interactive 3D plots directly in Jupyter Notebooks.

To do so you first need to install Plotly by running:

pip install plotly

You might also want to upgrade the library by running:

pip install plotly --upgrade

After that in you Jupyter Notebook you may write something like:

# Import dependencies
import plotly
import plotly.graph_objs as go

# Configure Plotly to be rendered inline in the notebook.
plotly.offline.init_notebook_mode()

# Configure the trace.
trace = go.Scatter3d(
    x=[1, 2, 3],  # <-- Put your data instead
    y=[4, 5, 6],  # <-- Put your data instead
    z=[7, 8, 9],  # <-- Put your data instead
    mode='markers',
    marker={
        'size': 10,
        'opacity': 0.8,
    }
)

# Configure the layout.
layout = go.Layout(
    margin={'l': 0, 'r': 0, 'b': 0, 't': 0}
)

data = [trace]

plot_figure = go.Figure(data=data, layout=layout)

# Render the plot.
plotly.offline.iplot(plot_figure)

As a result the following chart will be plotted for you in Jupyter Notebook and you'll be able to interact with it. Of course you will need to provide your specific data instead of suggeseted one.

A modern alternative:

const textToFind = 'Google';
const dd = document.getElementById ('MyDropDown');
dd.selectedIndex = [...dd.options].findIndex (option => option.text === textToFind);

Seems like both the conditions are met, perhaps key('contact') is the issue

 if(store.telefon) {
    detailItems.push( new DetailItem('contact', store.telefon, 'Anrufen', 'fontawesome|phone') );
}
if(store.email) {
    detailItems.push( new DetailItem('contact', store.email, 'Email', 'fontawesome|envelope') );
}

1. Make sure that the version of the m2e(clipse) plugin that you're running is at least 1.1.0

2. Close maven project - right click "Close Project"

3. Manualy remove all classpathentry with kind="var" in .classpath file
4. Open project

or

1. Remove maven project
2. Manualy rmeove .classpath 4 Reimport project

Rotate an image in android with delay:

imgSplash.animate().rotationBy(360f).setDuration(3000).setInterpolator(new LinearInterpolator()).start();

I've read through all seven pages, and I'm missing these:

String.Join

I've seen a lot of for-loops to convert a list of items to a string with separators. It's always a pain to make sure you doin't start with a separator and don't end with a separator. A built-in method makes this easier:

String.Join(",", new String[] { "a", "b", "c"});

TODO in comment

Not really a C# feature, more of a Visual Studio feature. When you start your comment with TODO, it's added to your Visual Studio Task List (View -> Task List. Comments)

// TODO: Implement this!
throw new NotImplementedException();

Extension methods meets Generics

You can combine extension methods with Generics, when you think of the tip earlier in this topic, you can add extensions to specific interfaces

public static void Process<T>(this T item) where T:ITest,ITest2 {}

Enumerable.Range

Just want a list of integers?

Enumerable.Range(0, 15)

I'll try to think of some more...

Ascii string to integer conversion is done by the atoi() function.

That's HTML, but yes, you can bang pretty much any selectors you like together.

#x.y { }

(And the HTML is fine too)

Generally Server JDK version will be lower than the deployed application (built with higher jdk version)

Note that TRUNCATE won't work if you have any referential integrity set.

In that case, this will work:

EXEC sp_MSForEachTable 'DISABLE TRIGGER ALL ON ?'
GO
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO
EXEC sp_MSForEachTable 'DELETE FROM ?'
GO
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
GO
EXEC sp_MSForEachTable 'ENABLE TRIGGER ALL ON ?'
GO

Edit: To be clear, the ? in the statements is a ?. It's replaced with the table name by the sp_MSForEachTable procedure.

throw $e->getMessage();

You try to throw a string

As a sidenote: Exceptions are usually to define exceptional states of the application and not for error messages after validation. Its not an exception, when a user gives you invalid data

Behold HTML comments:

The proper way to delete code without deleting it, of course, is to use version control, which enables you to resurrect old code from the past. Don't get into the habit of accumulating commented-out code in your pages, it's no fun. :)

Arrays are default passed by pointers. You can try modifying an array inside a function call for better understanding.

try this

provider = new CultureInfo("en-US");
DateTime.ParseExact("9/1/2009", "M/d/yyyy", provider);

Bye.

The type int is a primitive and it cannot be null, if you want to return null, mark the signature as

public Integer pollDecrementHigherKey(int x) {
    x = 10;

    if (condition) {
        return x; // This is auto-boxing, x will be automatically converted to Integer
    } else if (condition2) {
        return null; // Integer inherits from Object, so it's valid to return null
    } else {
        return new Integer(x); // Create an Integer from the int and then return
    }
    
    return 5; // Also will be autoboxed and converted into Integer
}

I'd suggest you use the newer assertThat() style asserts, which can easily describe all kinds of negations and automatically build a description of what you expected and what you got if the assertion fails:

assertThat(objectUnderTest, is(not(someOtherObject)));
assertThat(objectUnderTest, not(someOtherObject));
assertThat(objectUnderTest, not(equalTo(someOtherObject)));

All three options are equivalent, choose the one you find most readable.

To use the simple names of the methods (and allow this tense syntax to work), you need these imports:

import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;

If I understand the question, you may interested in this example in the Matplotlib gallery.

Yann's comment above provides a similar example.

Edit - Link above fixed. Corresponding code copied from the Matplotlib gallery:

from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt

host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)

par1 = host.twinx()
par2 = host.twinx()

offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right", axes=par2,
                                        offset=(offset, 0))

par2.axis["right"].toggle(all=True)

host.set_xlim(0, 2)
host.set_ylim(0, 2)

host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity")

par1.set_ylim(0, 4)
par2.set_ylim(1, 65)

host.legend()

host.axis["left"].label.set_color(p1.get_color())
par1.axis["right"].label.set_color(p2.get_color())
par2.axis["right"].label.set_color(p3.get_color())

plt.draw()
plt.show()

#plt.savefig("Test")

I needed the time and a slight variation on format. This works great for my purposes:

$((get-date).ToLocalTime()).ToString("yyyy-MM-dd HHmmss")

2019-08-16 215757

According to @mklement0 in comments, this should yield the same result:

(get-date).ToString("yyyy-MM-dd HHmmss")

This was once written for Gradle 2.x / 3.x in 2016 and is far outdated!! Please have a look at the documented solutions in Gradle 4 and up

To sum up both old answers (get best and minimum viable of both worlds):

some warm words first:

1. first, we need to define the sourceSet:

   sourceSets {
       integrationTest
   }
   

2. next we expand the sourceSet from test, therefor we use the test.runtimeClasspath (which includes all dependenciess from test AND test itself) as classpath for the derived sourceSet:

   sourceSets {
       integrationTest {
           compileClasspath += sourceSets.test.runtimeClasspath
           runtimeClasspath += sourceSets.test.runtimeClasspath // ***)
       }
   }
   

   • note) somehow this redeclaration / extend for sourceSets.integrationTest.runtimeClasspath is needed, but should be irrelevant since runtimeClasspath always expands output + runtimeSourceSet, don't get it

3. we define a dedicated task for just running integration tests:

   task integrationTest(type: Test) {
   }
   

4. Configure the integrationTest test classes and classpaths use. The defaults from the java plugin use the test sourceSet

   task integrationTest(type: Test) {
       testClassesDir = sourceSets.integrationTest.output.classesDir
       classpath = sourceSets.integrationTest.runtimeClasspath
   }
   

5. (optional) auto run after test

   integrationTest.dependsOn test
   

6. (optional) add dependency from check (so it always runs when build or check are executed)

   tasks.check.dependsOn(tasks.integrationTest)
   

7. (optional) add java,resources to the sourceSet to support auto-detection and create these "partials" in your IDE. i.e. IntelliJ IDEA will auto create sourceSet directories java and resources for each set if it doesn't exist:

   sourceSets {
        integrationTest {
            java
            resources
        }
   }
   

tl;dr

apply plugin: 'java'

// apply the runtimeClasspath from "test" sourceSet to the new one
// to include any needed assets: test, main, test-dependencies and main-dependencies
sourceSets {
    integrationTest {
        // not necessary but nice for IDEa's
        java
        resources

        compileClasspath += sourceSets.test.runtimeClasspath
        // somehow this redeclaration is needed, but should be irrelevant
        // since runtimeClasspath always expands compileClasspath
        runtimeClasspath += sourceSets.test.runtimeClasspath
    }
}

// define custom test task for running integration tests
task integrationTest(type: Test) {
    testClassesDir = sourceSets.integrationTest.output.classesDir
    classpath = sourceSets.integrationTest.runtimeClasspath
}
tasks.integrationTest.dependsOn(tasks.test)

referring to:

• gradle java chapter 45.7.1. Source set properties
• gradle java chapter 45.7.3. Some source set examples

Unfortunatly, the example code on github.com/gradle/gradle/subprojects/docs/src/samples/java/customizedLayout/build.gradle or …/gradle/…/withIntegrationTests/build.gradle seems not to handle this or has a different / more complex / for me no clearer solution anyway!

Without jQuery:

document.getElementById('file').onchange = function(){

  var file = this.files[0];

  var reader = new FileReader();
  reader.onload = function(progressEvent){
    // Entire file
    console.log(this.result);

    // By lines
    var lines = this.result.split('\n');
    for(var line = 0; line < lines.length; line++){
      console.log(lines[line]);
    }
  };
  reader.readAsText(file);
};

HTML:

<input type="file" name="file" id="file">

Remember to put your javascript code after the file field is rendered.

You could have a dictionary where the entries are a list of other dictionaries:

fruit_dict = dict()
fruit_dict['banana'] = [{'yellow': 24}]
fruit_dict['apple'] = [{'red': 12}, {'green': 14}]
print fruit_dict

Output:

{'banana': [{'yellow': 24}], 'apple': [{'red': 12}, {'green': 14}]}

Edit: As eumiro pointed out, you could use a dictionary of dictionaries:

fruit_dict = dict()
fruit_dict['banana'] = {'yellow': 24}
fruit_dict['apple'] = {'red': 12, 'green': 14}
print fruit_dict

Output:

{'banana': {'yellow': 24}, 'apple': {'green': 14, 'red': 12}}

db.getCollection('orders').aggregate([  
    {$group: { 
            _id: {name: "$name"},
            uniqueIds: {$addToSet: "$_id"},
            count: {$sum: 1}
        } 
    },
    {$match: { 
        count: {"$gt": 1}
        }
    }
])

First Group Query the group according to the fields.

Then we check the unique Id and count it, If count is greater then 1 then the field is duplicate in the entire collection so that thing is to be handle by $match query.

Convert without creating String object:

import java.nio.CharBuffer;
import java.nio.ByteBuffer;
import java.util.Arrays;

byte[] toBytes(char[] chars) {
  CharBuffer charBuffer = CharBuffer.wrap(chars);
  ByteBuffer byteBuffer = Charset.forName("UTF-8").encode(charBuffer);
  byte[] bytes = Arrays.copyOfRange(byteBuffer.array(),
            byteBuffer.position(), byteBuffer.limit());
  Arrays.fill(byteBuffer.array(), (byte) 0); // clear sensitive data
  return bytes;
}

Usage:

char[] chars = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};
byte[] bytes = toBytes(chars);
/* do something with chars/bytes */
Arrays.fill(chars, '\u0000'); // clear sensitive data
Arrays.fill(bytes, (byte) 0); // clear sensitive data

Solution is inspired from Swing recommendation to store passwords in char[]. (See Why is char[] preferred over String for passwords?)

Remember not to write sensitive data to logs and ensure that JVM won't hold any references to it.

The code above is correct but not effective. If you don't need performance but want security you can use it. If security also not a goal then do simply String.getBytes. Code above is not effective if you look down of implementation of encode in JDK. Besides you need to copy arrays and create buffers. Another way to convert is inline all code behind encode (example for UTF-8):

val xs: Array[Char] = "A ß € ?  ".toArray
val len = xs.length
val ys: Array[Byte] = new Array(3 * len) // worst case
var i = 0; var j = 0 // i for chars; j for bytes
while (i < len) { // fill ys with bytes
  val c = xs(i)
  if (c < 0x80) {
    ys(j) = c.toByte
    i = i + 1
    j = j + 1
  } else if (c < 0x800) {
    ys(j) = (0xc0 | (c >> 6)).toByte
    ys(j + 1) = (0x80 | (c & 0x3f)).toByte
    i = i + 1
    j = j + 2
  } else if (Character.isHighSurrogate(c)) {
    if (len - i < 2) throw new Exception("overflow")
    val d = xs(i + 1)
    val uc: Int = 
      if (Character.isLowSurrogate(d)) {
        Character.toCodePoint(c, d)
      } else {
        throw new Exception("malformed")
      }
    ys(j) = (0xf0 | ((uc >> 18))).toByte
    ys(j + 1) = (0x80 | ((uc >> 12) & 0x3f)).toByte
    ys(j + 2) = (0x80 | ((uc >>  6) & 0x3f)).toByte
    ys(j + 3) = (0x80 | (uc & 0x3f)).toByte
    i = i + 2 // 2 chars
    j = j + 4
  } else if (Character.isLowSurrogate(c)) {
    throw new Exception("malformed")
  } else {
    ys(j) = (0xe0 | (c >> 12)).toByte
    ys(j + 1) = (0x80 | ((c >> 6) & 0x3f)).toByte
    ys(j + 2) = (0x80 | (c & 0x3f)).toByte
    i = i + 1
    j = j + 3
  }
}
// check
println(new String(ys, 0, j, "UTF-8"))

Excuse me for using Scala language. If you have problems with converting this code to Java I can rewrite it. What about performance always check on real data (with JMH for example). This code looks very similar to what you can see in JDK[2] and Protobuf[3].

You have to create an instance of one of the subclasses. Stream is an abstract class that can't be instantiated directly.

There are a bunch of choices if you look at the bottom of the reference here:

Stream Class | Microsoft Developer Network

The most common probably being FileStream or MemoryStream. Basically, you need to decide where you wish the data backing your stream to come from, then create an instance of the appropriate subclass.

You should create the media dir appended to what getLocalPath() returns.

You are using the wrong build.gradle file.

In your top-level file you can't define an android block.

Just move this part inside the module/build.gradle file.

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

In theory, yes, it's just a matter of plugging things in. Zipfile can give you a file-like object for a file in a zip archive, and image.load will accept a file-like object. So something like this should work:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
try:
    image = pygame.image.load(imgfile, 'img_01.png')
finally:
    imgfile.close()

I also faced this issue. My Operating system is Ubuntu 18.04 and my PHP version is PHP 7.2.

Here's how I solved it:

Install Simplexml on your Ubuntu Server:

Here's an example for rotating about an arbitrary point (x,y) using only openCV

def rotate_about_point(x, y, degree, image):
    rot_mtx = cv.getRotationMatrix2D((x, y), angle, 1)
    abs_cos = abs(rot_mtx[0, 0])
    abs_sin = abs(rot_mtx[0, 1])
    rot_wdt = int(frm_hgt * abs_sin + frm_wdt * abs_cos)
    rot_hgt = int(frm_hgt * abs_cos + frm_wdt * abs_sin)
    rot_mtx += np.asarray([[0, 0, -lftmost_x],
                           [0, 0, -topmost_y]])
    rot_img = cv.warpAffine(image, rot_mtx, (rot_wdt, rot_hgt),
                            borderMode=cv.BORDER_CONSTANT)
    return rot_img

You can Try with

#python3
import hashlib
rawdata = "put your data here"
sha = hashlib.sha256(str(rawdata).encode("utf-8")).hexdigest() #For Sha256 hash
print(sha)
mdpass = hashlib.md5(str(sha).encode("utf-8")).hexdigest() #For MD5 hash
print(mdpass)

You can use the % operator to find the remainder of a division, and compare the result with 0.

Example:

if (number % divisor == 0)
{
    //code for perfect divisor
}
else
{
    //the number doesn't divide perfectly by divisor
}

It gets interesting when you have to pass parameters to this function as well.

Code jsfiddle

var obj = {method:function(p1,p2,p3){console.log("method:",arguments)}}

var str = "method('p1', 'p2', 'p3');"

var match = str.match(/^\s*(\S+)\((.*)\);\s*$/);

var func = match[1]
var parameters = match[2].split(',');
for(var i = 0; i < parameters.length; ++i) {
  // clean up param begninning
    parameters[i] = parameters[i].replace(/^\s*['"]?/,'');
  // clean up param end
  parameters[i] = parameters[i].replace(/['"]?\s*$/,'');
}

obj[func](parameters); // sends parameters as array
obj[func].apply(this, parameters); // sends parameters as individual values

WebAPI 2 now has a package for CORS which can be installed using : Install-Package Microsoft.AspNet.WebApi.Cors -pre -project WebServic

Once this is installed, follow this for the code :http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api

O(n) is big O notation used for writing time complexity of an algorithm. When you add up the number of executions in an algoritm you'll get an expression in result like 2N+2, in this expression N is the dominating term(the term having largest effect on expression if its value increases or decreases). Now O(N) is the time comlexity while N is dominating term. Example

For i= 1 to n;
  j= 0;
while(j<=n);
  j=j+1;

here total number of executions for inner loop are n+1 and total number of executions for outer loop are n(n+1)/2, so total number of executions for whole algorithm are n+1+n(n+1/2) = (n^2+3n)/2. here n^2 is the dominating term so the time complexity for this algorithm is O(n^2)

For me it was Package.json it was empty from dependencies even though i thought i did install them.. so I had to reinstall them with --save option in the end and verify they were added to the package.json.. and then push it again and it worked.

CSS auto-fit container between float:left & float:right divs solved my problem, thanks for your comments.

#left

    width:200px;
    float:left;
    background-color:antiquewhite;
    margin-left:10px;
}
#content
{
    overflow:hidden;
    margin-left:10px;
    background-color:AppWorkspace;
}

Warning!

This answer is now outdated. DOM Level 4 introduced MutationObserver, providing an effective replacement for the deprecated mutation events. See this answer to another question for a better solution than the one presented here. Seriously. Don't poll the DOM every 100 milliseconds; it will waste CPU power and your users will hate you.

Since mutation events were deprecated in 2012, and you have no control over the inserted elements because they are added by someone else's code, your only option is to continuously check for them.

function checkDOMChange()
{
    // check for any new element being inserted here,
    // or a particular node being modified

    // call the function again after 100 milliseconds
    setTimeout( checkDOMChange, 100 );
}

Once this function is called, it will run every 100 milliseconds, which is 1/10 (one tenth) of a second. Unless you need real-time element observation, it should be enough.

I needed all the videos to use the same codec for merging purposes
so this conversion is mp4 to mp4
it's in zsh but should easily be convertible to bash

for S (*.mp4) { ffmpeg -i $S -c:v libx264 -r 30  new$S }

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

IE7 doesn't know inline-block. You must add:

display:inline;
zoom: 1;

In the case you need to do some asynchronous code (like sending a message to the server that the user is not focused on your page right now), the event beforeunload will not give time to the async code to run. In the case of async I found that the visibilitychange and mouseleave events are the best options. These events fire when the user change tab, or hiding the browser, or taking the courser out of the window scope.

document.addEventListener('mouseleave', e=>{_x000D_
     //do some async code_x000D_
})_x000D_
_x000D_
document.addEventListener('visibilitychange', e=>{_x000D_
     if (document.visibilityState === 'visible') {_x000D_
   //report that user is in focus_x000D_
    } else {_x000D_
     //report that user is out of focus_x000D_
    }  _x000D_
})

Just click on "Build" on the top menu and then click on "Publish ".... Then a pop up will open and there u can define the folder which u want to save the .exe file and by clicking "Next" will allow u to set up the advanced settings... DONE!

I was also facing the same issue with Postman for multipart. I fixed it by doing the following steps:

• Do not select Content-Type in the Headers section.
• In Body tab of Postman you should select form-data and select file type.

It worked for me.

you can use

the character equivalent to 0x63 is 'c' but byte equivalent to it is 99

System.out.println("byte "+(char)0x63); 

I found that piping the array to the Out-String cmdlet works well too.

For example:

PS C:\> $a  | out-string

This
Is
a
cat

It depends on your end goal as to which method is the best to use.

The problem happens when a floated element is within a container box, that element does not automatically force the container’s height adjust to the floated element. When an element is floated, its parent no longer contains it because the float is removed from the flow. You can use 2 methods to fix it:

• { clear: both; }
• clearfix

Once you understand what is happening, use the method below to “clearfix” it.

.clearfix:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

.clearfix {
    display: inline-block;
}

html[xmlns] .clearfix {
    display: block;
}

* html .clearfix {
    height: 1%;
}

Demonstration :)

I did it in ES6 with a little improvement:

arr.reduce((a, b) => ({x: a.x + b.x})).x

return number

As you say, ordinal is a bit risky. Consider for example:

public enum Boolean {
    TRUE, FALSE
}

public class BooleanTest {
    @Test
    public void testEnum() {
        assertEquals(0, Boolean.TRUE.ordinal());
        assertEquals(1, Boolean.FALSE.ordinal());
    }
}

If you stored this as ordinals, you might have rows like:

> SELECT STATEMENT, TRUTH FROM CALL_MY_BLUFF

"Alice is a boy"      1
"Graham is a boy"     0

But what happens if you updated Boolean?

public enum Boolean {
    TRUE, FILE_NOT_FOUND, FALSE
}

This means all your lies will become misinterpreted as 'file-not-found'

Better to just use a string representation

Typically this happens when you are trying to load a non-html resource (e.g the jquery library script file as type text/javascript) and the server, instead of returning the expected JS resource, returns HTML instead - typically a 404 page.

The browser then attempts to parse the resource as JS, but since what was actually returned was an HTML page, the parsing fails with a syntax error, and since an HTML page will typically start with a < character, this is the character that is highlighted in the syntax error exception.

when you want to keep the directory option,you can put the index.php ahead of $uri like this.

try_files /index.php $uri $uri/

Try this: tar -cf file.tar file-to-compress ; xz -z file.tar

Note:

1. tar.gz and tar.xz are not the same; xz provides better compression.
2. Don't use pipe | because this runs commands simultaneously. Using ; or & executes commands one after another.

Check whether title has any value or not. If not, then retrive the value using Id.

<form>
Title : <input type="text" id="title" size="40" name="title" value = ''/>
<input type="button" onclick="headingSearch(this.form)" value="Submit"/><br /><br />
</form>
<script type="text/javascript">
function headingSearch(f)
{
    var title=jQuery('#title').val();
    $.ajax({
      type: "POST",
      url: "edit.php",
      data: {title:title} ,
      success: function(data) {
    $('.center').html(data); 
}
});
}
</script>

Try this code.

In php code, use echo instead of return. Only then, javascript data will have its value.

You can also sort by the _id field. For example, to get the most recent record, you can do,

const mostRecentRecord = await db.collection.findOne().sort({ _id: -1 });

It's much quicker too, because I'm more than willing to bet that your date field is not indexed.

As others mentioned, there is no "first item", since dictionaries have no guaranteed order (they're implemented as hash tables). If you want, for example, the value corresponding to the smallest key, thedict[min(thedict)] will do that. If you care about the order in which the keys were inserted, i.e., by "first" you mean "inserted earliest", then in Python 3.1 you can use collections.OrderedDict, which is also in the forthcoming Python 2.7; for older versions of Python, download, install, and use the ordered dict backport (2.4 and later) which you can find here.

Python 3.7 Now dicts are insertion ordered.

<script type="text/javascript">
    var IdAry=['reports1'];
    window.onload=function() {
     for (var zxc0=0;zxc0<IdAry.length;zxc0++){
      var el=document.getElementById(IdAry[zxc0]);
      if (el){
       el.onmouseover=function() {
         changeText(this,'hide','show')
        }
       el.onmouseout=function() {
         changeText(this,'show','hide');
        }
      }
     }
    }
    function changeText(obj,cl1,cl2) {
       obj.getElementsByTagName('SPAN')[0].className=cl1;
       obj.getElementsByTagName('SPAN')[1].className=cl2;
    }
</script>

ur html should look like this

<p id="reports1">
                <span id="span1">Test Content</span>
                <span class="hide">

                    <br /> <br /> This is the content that appears when u hover on the it
                </span>
            </p>

I have checked that the output redirection works with javaw:

javaw -cp ... mypath.MyClass ... arguments 1>log.txt 2>err.txt

It means, if the Java application prints out anything via System.out or System.err, it is written to those files, as also with using java (without w). Especially on starting java, the JRE may write starting errors (class not found) on the error output pipe. In this respect, it is essential to know about errors. I suggest to use the console redirection in any case if javaw is invoked.

In opposite if you use

start java .... 1>log.txt 2>err.txt

With the Windows console start command, the console output redirection does not work with java nor with javaw.

Explanation why it is so: I think that javaw opens an internal process in the OS (adequate using the java.lang.Process class), and transfers a known output redirection to this process. If no redirection is given on the command line, nothing is redirected and the internal started process for javaw doesn't have any console outputs. The behavior for java.lang.Process is similar. The virtual machine may use this internal feature for javaw too.

If you use 'start', the Windows console creates a new process for Windows to execute the command after start, but this mechanism does not use a given redirection for the started sub process, unfortunately.

You could use row_factory, as in the example in the docs:

import sqlite3

def dict_factory(cursor, row):
    d = {}
    for idx, col in enumerate(cursor.description):
        d[col[0]] = row[idx]
    return d

con = sqlite3.connect(":memory:")
con.row_factory = dict_factory
cur = con.cursor()
cur.execute("select 1 as a")
print cur.fetchone()["a"]

or follow the advice that's given right after this example in the docs:

If returning a tuple doesn’t suffice and you want name-based access to columns, you should consider setting row_factory to the highly-optimized sqlite3.Row type. Row provides both index-based and case-insensitive name-based access to columns with almost no memory overhead. It will probably be better than your own custom dictionary-based approach or even a db_row based solution.

onreadystatechange Stores a function (or the name of a function) to be called automatically each time the readyState property changes readyState Holds the status of the XMLHttpRequest. Changes from 0 to 4:

0: request not initialized

1: server connection established

2: request received

3: processing request

4: request finished and response is ready

status 200: "OK"

404: Page not found

in normal time, checkboxes return an on/off value.

you can verify it with this code:

<form action method="POST">
      <input type="checkbox" name="hello"/>
</form>

<?php
if(isset($_POST['hello'])) echo('<p>'.$_POST['hello'].'</p>');
?>

this will return

<p>off</p>

or

<p>on</p>

You could try this:

SELECT * 
FROM table 
ORDER BY (c_counts+f_counts) 
LIMIT 20

Implement your own implementation of IValueConverter. A sample implementation is at

http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter.aspx

In your Convert method, have it return the values you'd like instead of the defaults.

An alternative I haven't seen as answer yet is the java.io.PrintWriter.

StringWriter stringWriter = new StringWriter();
PrintWriter writer = new PrintWriter(stringWriter);
writer.println("It was the best of times, it was the worst of times");
writer.println("it was the age of wisdom, it was the age of foolishness,");
writer.println("it was the epoch of belief, it was the epoch of incredulity,");
writer.println("it was the season of Light, it was the season of Darkness,");
writer.println("it was the spring of hope, it was the winter of despair,");
writer.println("we had everything before us, we had nothing before us");
String string = stringWriter.toString();

Also the fact that java.io.BufferedWriter has a newLine() method is unmentioned.

Do you mean sort of like this?

 Dictionary<int, string[]> dictionaty  = new Dictionary<int, string[]>() {
            {1, new string[]{"a","b","c"} },
            {2, new string[]{"222","str"} }
        };

str.replace is the wrong function for what you want to do (apart from it being used incorrectly). You want to replace any character of a set with a space, not the whole set with a single space (the latter is what replace does). You can use translate like this:

removeSpecialChars = z.translate ({ord(c): " " for c in "!@#$%^&*()[]{};:,./<>?\|`~-=_+"})

This creates a mapping which maps every character in your list of special characters to a space, then calls translate() on the string, replacing every single character in the set of special characters with a space.

I've created an Age struct, which looks like this:

public struct Age : IEquatable<Age>, IComparable<Age>
{
    private readonly int _years;
    private readonly int _months;
    private readonly int _days;

    public int Years  { get { return _years; } }
    public int Months { get { return _months; } }
    public int Days { get { return _days; } }

    public Age( int years, int months, int days ) : this()
    {
        _years = years;
        _months = months;
        _days = days;
    }

    public static Age CalculateAge( DateTime dateOfBirth, DateTime date )
    {
        // Here is some logic that ressembles Mike's solution, although it
        // also takes into account months & days.
        // Ommitted for brevity.
        return new Age (years, months, days);
    }

    // Ommited Equality, Comparable, GetHashCode, functionality for brevity.
}

You can use angularjs form state form.$submitted. Initially form.$submitted value will be false and will became true after successful form submit.

Older IE and Firefox browsers attach the scrollbar to the documentElement, or what would be the <html> tag in HTML.

All other browsers attach the scrollbar to document.body, or what would be the <body> tag in HTML.

The correct solution would be to check which one to use, depending on browser

var doc = document.documentElement.clientHeight ? document.documentElement : document.body;
var s   = $(doc).scrollTop();

jQuery does make this a little easier, when passing in either window or document jQuery's scrollTop does a similar check and figures it out, so either of these should work cross-browser

var s = $(document).scrollTop();

or

var s = $(window).scrollTop();

jQuery scrollTop() docs

Description: Get the current vertical position of the scroll bar for the first element in the set of matched elements or set the vertical position of the scroll bar for every matched element.

...nothing that works for my div, just the full page

If it's for a DIV, you'd have to target the element that has the scrollbar attached, to get the scrolled amount

$('div').scrollTop();

If you need to get the elements distance from the top of the document, you can also do

$('div').offset().top

Is this what you are looking for?

 If ActiveCell.Value == "Total" Then

    ActiveCell.offset(1,0).Value = "-"

 End If

Of you could do something like this

 Dim celltxt As String
 celltxt = ActiveSheet.Range("C6").Text
 If InStr(1, celltxt, "Total") Then
    ActiveCell.offset(1,0).Value = "-"
 End If

Which is similar to what you have.

MacOS

If you want to set up a windows environment with Virtualbox on a mac, just use the default NAT settings on the adapter, and in your windows VM, go to hosts file and add the following:

10.0.2.2       localhost
10.0.2.2       127.0.0.1

Differently from the answers above, it's important to include both lines, otherwise it won't work.

From iOS8 Apple provide new UIAlertController class which you can use instead of UIAlertView which is now deprecated, it is also stated in deprecation message:

UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead

So you should use something like this

UIAlertController * alert = [UIAlertController
                alertControllerWithTitle:@"Title"
                                 message:@"Message"
                          preferredStyle:UIAlertControllerStyleAlert];



UIAlertAction* yesButton = [UIAlertAction
                    actionWithTitle:@"Yes, please"
                              style:UIAlertActionStyleDefault
                            handler:^(UIAlertAction * action) {
                                //Handle your yes please button action here
                            }];

UIAlertAction* noButton = [UIAlertAction
                        actionWithTitle:@"No, thanks"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                   //Handle no, thanks button                
                                }];

[alert addAction:yesButton];
[alert addAction:noButton];

[self presentViewController:alert animated:YES completion:nil];

If you have access to the application package, then you can install with the -r option and it will kill the process if it is currently running as a side effect. Like this:

adb -d install -r MyApp.apk ; adb -d shell am start -a android.intent.action.MAIN -n com.MyCompany.MyApp/.MyActivity

The -r option preserves the data currently associated with the app. However, if you want a clean slate like you mention you might not want to use that option.

If what you're really doing is manipulating a CSV file itself, Nelson's answer makes sense. However, my suspicion is that the CSV is simply an artifact of the problem you're solving. In C++, that probably means you have something like this as your data model:

struct Customer {
    int id;
    std::string first_name;
    std::string last_name;
    struct {
        std::string street;
        std::string unit;
    } address;
    char state[2];
    int zip;
};

Thus, when you're working with a collection of data, it makes sense to have std::vector<Customer> or std::set<Customer>.

With that in mind, think of your CSV handling as two operations:

// if you wanted to go nuts, you could use a forward iterator concept for both of these
class CSVReader {
public:
    CSVReader(const std::string &inputFile);
    bool hasNextLine();
    void readNextLine(std::vector<std::string> &fields);
private:
    /* secrets */
};
class CSVWriter {
public:
    CSVWriter(const std::string &outputFile);
    void writeNextLine(const std::vector<std::string> &fields);
private:
    /* more secrets */
};
void readCustomers(CSVReader &reader, std::vector<Customer> &customers);
void writeCustomers(CSVWriter &writer, const std::vector<Customer> &customers);

Read and write a single row at a time, rather than keeping a complete in-memory representation of the file itself. There are a few obvious benefits:

1. Your data is represented in a form that makes sense for your problem (customers), rather than the current solution (CSV files).
2. You can trivially add adapters for other data formats, such as bulk SQL import/export, Excel/OO spreadsheet files, or even an HTML <table> rendering.
3. Your memory footprint is likely to be smaller (depends on relative sizeof(Customer) vs. the number of bytes in a single row).
4. CSVReader and CSVWriter can be reused as the basis for an in-memory model (such as Nelson's) without loss of performance or functionality. The converse is not true.

Not sure if there's terrible reasons to do this or not, but it seems to work with me on the latest version of Chrome/Firefox without any visible performance problems with quite a lot of elements on the page.

*:not(:hover)>.parent-hover-show{
    display:none;
}

But this way, all you need is to apply parent-hover-show to an element and the rest is taken care of, and you can keep whatever default display type you want without it always being "block" or making multiple classes for each type.

This is working for me. The difference is here with execSQL and rawQuery. The rawQuery use most in searching case and execSQL mostly used in apply operations.

Yes, that is correct.

Not putting an expires part in will create a session cookie, whether it is created in JavaScript or on the server.

This is an important question. The SSL 3 protocol (1996) is irreparably broken by the Poodle attack published 2014. The IETF have published "SSLv3 MUST NOT be used". Web browsers are ditching it. Mozilla Firefox and Google Chrome have already done so.

Two excellent tools for checking protocol support in browsers are SSL Lab's client test and https://www.howsmyssl.com/ . The latter does not require Javascript, so you can try it from .NET's HttpClient:

// set proxy if you need to
// WebRequest.DefaultWebProxy = new WebProxy("http://localhost:3128");

File.WriteAllText("howsmyssl-httpclient.html", new HttpClient().GetStringAsync("https://www.howsmyssl.com").Result);

// alternative using WebClient for older framework versions
// new WebClient().DownloadFile("https://www.howsmyssl.com/", "howsmyssl-webclient.html");

The result is damning:

Your client is using TLS 1.0, which is very old, possibly susceptible to the BEAST attack, and doesn't have the best cipher suites available on it. Additions like AES-GCM, and SHA256 to replace MD5-SHA-1 are unavailable to a TLS 1.0 client as well as many more modern cipher suites.

That's concerning. It's comparable to 2006's Internet Explorer 7.

To list exactly which protocols a HTTP client supports, you can try the version-specific test servers below:

var test_servers = new Dictionary<string, string>();
test_servers["SSL 2"] = "https://www.ssllabs.com:10200";
test_servers["SSL 3"] = "https://www.ssllabs.com:10300";
test_servers["TLS 1.0"] = "https://www.ssllabs.com:10301";
test_servers["TLS 1.1"] = "https://www.ssllabs.com:10302";
test_servers["TLS 1.2"] = "https://www.ssllabs.com:10303";

var supported = new Func<string, bool>(url =>
{
    try { return new HttpClient().GetAsync(url).Result.IsSuccessStatusCode; }
    catch { return false; }
});

var supported_protocols = test_servers.Where(server => supported(server.Value));
Console.WriteLine(string.Join(", ", supported_protocols.Select(x => x.Key)));

I'm using .NET Framework 4.6.2. I found HttpClient supports only SSL 3 and TLS 1.0. That's concerning. This is comparable to 2006's Internet Explorer 7.

Update: It turns HttpClient does support TLS 1.1 and 1.2, but you have to turn them on manually at System.Net.ServicePointManager.SecurityProtocol. See https://stackoverflow.com/a/26392698/284795

I don't know why it uses bad protocols out-the-box. That seems a poor setup choice, tantamount to a major security bug (I bet plenty of applications don't change the default). How can we report it?

textarea {
width: 700px;

assign your required width and height for the textarea and then use. resize: none ; css property which will disable the textarea's stretchable property.

It is easy to make itertools.groupby work for you to get an iterable of iterables, without creating any temporary lists:

groupby(iterable, (lambda x,y: (lambda z: x.next()/y))(count(),100))

Don't get put off by the nested lambdas, outer lambda runs just once to put count() generator and the constant 100 into the scope of the inner lambda.

I use this to send chunks of rows to mysql.

for k,v in groupby(bigdata, (lambda x,y: (lambda z: x.next()/y))(count(),100))):
    cursor.executemany(sql, v)

If you really want to use String:

NSString *number = [[NSString alloc] initWithFormat:@"%d", 123];

But I would recommend using NSNumber:

NSNumber *number = [[NSNumber alloc] initWithInt:123];

Then just add it to the array.

[array addObject:number];

Don't forget to release it after that, since you created it above.

[number release];

Function MySheet()

  ' uncomment the below line to make it Volatile
  'Application.Volatile
   MySheet = Application.Caller.Worksheet.Name

I normally set paths in

~/.bashrc

However for Java, I followed instructions at https://askubuntu.com/questions/55848/how-do-i-install-oracle-java-jdk-7

and it was sufficient for me.

you can also define multiple java_home's and have only one of them active (rest commented).

suppose in your bashrc file, you have

export JAVA_HOME=......jdk1.7

#export JAVA_HOME=......jdk1.8

notice 1.8 is commented. Once you do

source ~/.bashrc

jdk1.7 will be in path.

you can switch them fairly easily this way. There are other more permanent solutions too. The link I posted has that info.

Simply use \1 instead of $1:

In [1]: import re

In [2]: method = 'images/:id/huge'

In [3]: re.sub(r'(:[a-z]+)', r'<span>\1</span>', method)
Out[3]: 'images/<span>:id</span>/huge'

Also note the use of raw strings (r'...') for regular expressions. It is not mandatory but removes the need to escape backslashes, arguably making the code slightly more readable.

There is a way to remove a child element via SimpleXml. The code looks for a element, and does nothing. Otherwise it adds the element to a string. It then writes out the string to a file. Also note that the code saves a backup before overwriting the original file.

$username = $_GET['delete_account'];
echo "DELETING: ".$username;
$xml = simplexml_load_file("users.xml");

$str = "<?xml version=\"1.0\"?>
<users>";
foreach($xml->children() as $child){
  if($child->getName() == "user") {
      if($username == $child['name']) {
        continue;
    } else {
        $str = $str.$child->asXML();
    }
  }
}
$str = $str."
</users>";
echo $str;

$xml->asXML("users_backup.xml");
$myFile = "users.xml";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $str);
fclose($fh);

The concatenation operator '&' is allowed on the right side of the signal assignment operator '<=', only

This is an interesting question, but I don't think this is actually possible. Whether or not two colors "fit" as background and foreground colors is dependent upon display technology and physiological characteristics of human vision, but most importantly on upon personal tastes shaped by experience. A quick run through MySpace shows pretty clearly that not all human beings perceive colors in the same way. I don't think this is a problem that can be solved algorithmically, although there may be a huge database somewhere of acceptable matching colors.

My solution to get the higher key is as follows:

max(array_keys($values['Users']));

Small and universal solution:

expr "$string" : "$prefix\(.*\)$suffix"

Flex Solution

It is perfectly fine if you want to go with the display: table-cell solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;. flex is something which has a decent support.

.wrap {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  border: 1px solid #aaa;_x000D_
  margin: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
  align-self: flex-end;_x000D_
}

<div class="wrap">_x000D_
  <span>Align me to the bottom</span>_x000D_
</div>

In the above example, we first set the parent element to display: flex; and later, we use align-self to flex-end. This helps you push the item to the end of the flex parent.

Old Solution (Valid if you are not willing to use flex)

If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell; with vertical-align: bottom; is enough

div {_x000D_
  display: table-cell;_x000D_
  vertical-align: bottom;_x000D_
  border: 1px solid #f00;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
}

<div>Hello</div>

You can create a extension on DispatchQueue and add function delay which uses DispatchQueue asyncAfter function internally

extension DispatchQueue {
   static func delay(_ delay: DispatchTimeInterval, closure: @escaping () -> ()) {
      DispatchQueue.main.asyncAfter(deadline: .now() + delay, execute: closure)
   }
}

and use

DispatchQueue.delay(.milliseconds(10)) {
   print("task to be done")
}

This might help to understand what is recorded at what level Loggers may be assigned levels. Levels are instances of the log4net.Core.Level class. The following levels are defined in order of increasing severity - Log Level.

Number of levels recorded for each setting level:

 ALL    DEBUG   INFO    WARN    ERROR   FATAL   OFF
•All                        
•DEBUG  •DEBUG

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

I had the same problem and the solution was to use my own function instead of json_encode()

echo '["' . implode('","', $row) . '"]';

You are looking for np.matmul(X, y). In Python 3.5+ you can use X @ y.

With a FrameLayout you can place a text on top of an image view, the frame layout holding both an imageView and a textView.

If that's not enough and you want something more fancy like 'drawing' text, you need to draw text on a canvas - a sample is here: How to draw RTL text (Arabic) onto a Bitmap and have it ordered properly?

Despite this being against the general SO policy on these matters, this seems to be what the OP genuinely wants:

If you'd like, you could also try creating the appropriate batch or script file containing the single line:

java -jar MyJar.jar

Or in many cases on windows just double clicking the executable jar.

const is similar to static we can access both varables with class name but diff is static variables can be modified and const can not.

I made this plugin. There is some css interference taking place.

It's your border on the slider itself. Either use

box-sizing: border-box 

to absorb the border width, or put the border on the content inside the slide.

In Codeignitor version 3.0.x the system/core/Codeigniter.php do not contain the time constraint as well as inserting

ini_set('MAX_EXECUTION_TIME', -1);  

will not work since codeignitor will override that with its own function set_time_limit() . So either you have to delete that function from codeignitor or simply you can insert

set_time_limit('1000');

in the beginning of the php file if you wanna change that to 1000 seconds. Set the time to 0 (zero) if you want to run it as long as it want.

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

Using ...
search = (^.*import )(.*)(\(.*\):)
replace = $1$2

...replaces ...

from checks import checklist(_list):

...with...

from checks import checklist

Blocks in regex are delineated by parenthesis (which are not preceded by a "\")

(^.*import ) finds "from checks import " and loads it to $1 (eclipse starts counting at 1)

(.*) find the next "everything" until the next encountered "(" and loads it to $2. $2 stops at the "(" because of the next part (see next line below)

(\(.*\):) says "at the first encountered "(" after starting block $2...stop block $2 and start $3. $3 gets loaded with the "('any text'):" or, in the example, the "(_list):"

Then in the replace, just put the $1$2 to replace all three blocks with just the first two.

If someone was up for it they could port the excellent perl module File::Type to .NET. In the code is a set of file header magic number look ups for each file type or regex matches.

Here's a .NET file type detecting library http://filetypedetective.codeplex.com/ but it only detects a smallish number of files at the moment.

You'd have to parse the string yourself:

function getProperty(obj, prop) {
    var parts = prop.split('.');

    if (Array.isArray(parts)) {
        var last = parts.pop(),
        l = parts.length,
        i = 1,
        current = parts[0];

        while((obj = obj[current]) && i < l) {
            current = parts[i];
            i++;
        }

        if(obj) {
            return obj[last];
        }
    } else {
        throw 'parts is not valid array';
    }
}

This required that you also define array indexes with dot notation:

var part3name1 = "part3.0.name";

It makes the parsing easier.

You have to explicitly define the constructor in B and explicitly call the constructor for the parent.

B(int x) : A(x) { }

or

B() : A(5) { }

Set your HTML as

 <div id="body" hidden="">
 <h1>Numbers</h1>
 </div>
 <div id="body1" hidden="hidden">
 Body 1
 </div>

And now set the javascript as

     function changeDiv()
      {
      document.getElementById('body').hidden = "hidden"; // hide body div tag
      document.getElementById('body1').hidden = ""; // show body1 div tag
      document.getElementById('body1').innerHTML = "If you can see this, JavaScript function worked"; 
      // display text if JavaScript worked
       }

Check, it works.

I do not work with google android but I think you'll find it's not that hard to get this working. If you read the relevant bit of the java tutorial you'll see that a registered cookiehandler gets callbacks from the HTTP code.

So if there is no default (have you checked if CookieHandler.getDefault() really is null?) then you can simply extend CookieHandler, implement put/get and make it work pretty much automatically. Be sure to consider concurrent access and the like if you go that route.

edit: Obviously you'd have to set an instance of your custom implementation as the default handler through CookieHandler.setDefault() to receive the callbacks. Forgot to mention that.

#include <iostream>
#include <sys/time.h>

From what I know, respond_to is a method attached to the ActionController, so you can use it in every single controller, because all of them inherits from the ActionController. Here is the Rails respond_to method:

def respond_to(&block)
  responder = Responder.new(self)
  block.call(responder)
  responder.respond
end

You are passing it a block, like I show here:

respond_to <<**BEGINNING OF THE BLOCK**>> do |format|
  format.html
  format.xml  { render :xml => @whatever }
end <<**END OF THE BLOCK**>>

The |format| part is the argument that the block is expecting, so inside the respond_to method we can use that. How?

Well, if you notice we pass the block with a prefixed & in the respond_to method, and we do that to treat that block as a Proc. Since the argument has the ".xml", ".html" we can use that as methods to be called.

What we basically do in the respond_to class is call methods ".html, .xml, .json" to an instance of a Responder class.

I didn't understand it until I played around with it myself, so I figured there would be others who were confused as well. Say you are working on the user whose id == 6 and whose no_of_logins == 30 when you start.

# 1 (bad)
user.no_of_logins += 1
# result: UPDATE user SET no_of_logins = 31 WHERE user.id = 6

# 2 (bad)
user.no_of_logins = user.no_of_logins + 1
# result: UPDATE user SET no_of_logins = 31 WHERE user.id = 6

# 3 (bad)
setattr(user, 'no_of_logins', user.no_of_logins + 1)
# result: UPDATE user SET no_of_logins = 31 WHERE user.id = 6

# 4 (ok)
user.no_of_logins = User.no_of_logins + 1
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

# 5 (ok)
setattr(user, 'no_of_logins', User.no_of_logins + 1)
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

The point

By referencing the class instead of the instance, you can get SQLAlchemy to be smarter about incrementing, getting it to happen on the database side instead of the Python side. Doing it within the database is better since it's less vulnerable to data corruption (e.g. two clients attempt to increment at the same time with a net result of only one increment instead of two). I assume it's possible to do the incrementing in Python if you set locks or bump up the isolation level, but why bother if you don't have to?

A caveat

If you are going to increment twice via code that produces SQL like SET no_of_logins = no_of_logins + 1, then you will need to commit or at least flush in between increments, or else you will only get one increment in total:

# 6 (bad)
user.no_of_logins = User.no_of_logins + 1
user.no_of_logins = User.no_of_logins + 1
session.commit()
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

# 7 (ok)
user.no_of_logins = User.no_of_logins + 1
session.flush()
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6
user.no_of_logins = User.no_of_logins + 1
session.commit()
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

your issue will be resolved by properly defining cascading depedencies or by saving the referenced entities before saving the entity that references. Defining cascading is really tricky to get right because of all the subtle variations in how they are used.

Here is how you can define cascades:

@Entity
public class Userrole implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long userroleid;

    private Timestamp createddate;

    private Timestamp deleteddate;

    private String isactive;

    //bi-directional many-to-one association to Role
    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="ROLEID")
    private Role role;

    //bi-directional many-to-one association to User
    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="USERID")
    private User user;

}

In this scenario, every time you save, update, delete, etc Userrole, the assocaited Role and User will also be saved, updated...

Again, if your use case demands that you do not modify User or Role when updating Userrole, then simply save User or Role before modifying Userrole

Additionally, bidirectional relationships have a one-way ownership. In this case, User owns Bloodgroup. Therefore, cascades will only proceed from User -> Bloodgroup. Again, you need to save User into the database (attach it or make it non-transient) in order to associate it with Bloodgroup.

I hope these simple steps will help:

20 % 3 = 2 

1. 20 / 3 = 6; do not include the .6667 – just ignore it
2. 3 * 6 = 18
3. 20 - 18 = 2, which is the remainder of the modulo

If all else fails you can also use

"My text needs a line break here" + System.Environment.NewLine + " This should be a new line"

i.ToString("00")

or

i.ToString("000")

depending on what you want

Look at the MSDN article on custom numeric format strings for more options: http://msdn.microsoft.com/en-us/library/0c899ak8(VS.71).aspx

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

A BehaviorSubject holds one value. When it is subscribed it emits the value immediately. A Subject doesn't hold a value.

Subject example (with RxJS 5 API):

const subject = new Rx.Subject();
subject.next(1);
subject.subscribe(x => console.log(x));

Console output will be empty

BehaviorSubject example:

const subject = new Rx.BehaviorSubject(0);
subject.next(1);
subject.subscribe(x => console.log(x));

Console output: 1

In addition:

• BehaviorSubject should be created with an initial value: new Rx.BehaviorSubject(1)
• Consider ReplaySubject if you want the subject to hold more than one value

The following solution worked for me in Bootstrap 3.3.4:

CSS:

/*no collapse*/

.navbar-collapse.collapse.off {
    display: block!important;
}
.navbar-collapse.collapse.off ul {
    margin: 0;
    padding: 0;
}

.navbar-nav.no-collapse>li,
.navbar-nav.no-collapse {
    float: left !important;
}

.navbar-right.no-collapse {
    float: right!important;
}

then add the .no-collapse class to each of the lists and the .off class to the main container. Here is an example written in jade:

nav.navbar.navbar-default.navbar-fixed-top
        .container-fluid
            .collapse.navbar-collapse.off
                ul.nav.navbar-nav.no-collapse
                    li
                        a(href='#' class='glyph')
                            i(class='glyphicon glyphicon-info-sign')
                ul.nav.navbar-nav.navbar-right.no-collapse
                    li.dropdown
                        a.dropdown-toggle(href='#', data-toggle='dropdown' role='button' aria-expanded='false')
                            | Tools
                            span.caret
                        ul.dropdown-menu(role='menu')
                            li
                                a(href='#') Tool #1
                    li
                        a(href='#')

Here's another simple way using Runnable interface in Thread Constructor

public class Demo {
    public static void main(String[] args) {
        Thread t1 = new Thread(new Runnable() {

            @Override
            public void run() {
                for(int i = 0; i < 5; i++){
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("Thread T1 : "+i);
                }
            }
        });

        Thread t2 = new Thread(new Runnable() {

            @Override
            public void run() {
                for(int i = 0; i < 5; i++) {
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("Thread T2 : "+i);
                }
            }
        });

        Thread t3 = new Thread(new Runnable() {

            @Override
            public void run() {
                for(int i = 0; i < 5; i++){
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("Thread T3 : "+i);
                }
            }
        });

        t1.start();
        t2.start();
        t3.start();
    }
}

Use an abstract class instead. So, you would have something like:

public bool Foo<T>() where T : CBase;

Run gradle -q dependencies (or gradle -q :projectName:dependencies) to generate a dependency report. You should see where r7 is coming from, such as:

compile - Classpath for compiling the main sources.
+--- com.commonsware.cwac:camera-v9:0.5.4
|    +--- com.actionbarsherlock:actionbarsherlock:4.4.0
|    |    \--- com.google.android:support-v4:r7
|    +--- com.commonsware.cwac:camera:0.5.4
|    \--- com.android.support:support-v4:18.0.+ -> 18.0.0
\--- com.android.support:support-v4:18.0.+ -> 18.0.0

Then, use the exclude directive to block that dependency. In my case, it is coming from my CWAC-Camera library, and so I use:

dependencies {
    compile('com.commonsware.cwac:camera-v9:0.5.4') {
      exclude module: 'support-v4'
    }

    compile 'com.android.support:support-v4:18.0.+'
}

(where the second compile statement indicates what version you actually want)

That should clear matters up, as you will see if you run the dependency report again:

compile - Classpath for compiling the main sources.
+--- com.commonsware.cwac:camera-v9:0.5.4
|    +--- com.actionbarsherlock:actionbarsherlock:4.4.0
|    \--- com.commonsware.cwac:camera:0.5.4
\--- com.android.support:support-v4:18.0.+ -> 18.0.0

MSI is basically an installer from Microsoft that is built into windows. It associates components with features and contains installation control information. It is not necessary that this file contains actual user required files i.e the application programs which user expects. MSI can contain another setup.exe inside it which the MSI wraps, which actually contains the user required files.

Hope this clears you doubt.

This is my 2 cents based on Grax's answer, but with two parameters required for a generic method.

Assume your method is defined as follows in an Helpers class:

public class Helpers
{
    public static U ConvertCsvDataToCollection<U, T>(string csvData)
    where U : ObservableCollection<T>
    {
      //transform code here
    }
}

In my case, U type is always an observable collection storing object of type T.

As I have my types predefined, I first create the "dummy" objects that represent the observable collection (U) and the object stored in it (T) and that will be used below to get their type when calling the Make

object myCollection = Activator.CreateInstance(collectionType);
object myoObject = Activator.CreateInstance(objectType);

Then call the GetMethod to find your Generic function:

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

So far, the above call is pretty much identical as to what was explained above but with a small difference when you need have to pass multiple parameters to it.

You need to pass an Type[] array to the MakeGenericMethod function that contains the "dummy" objects' types that were create above:

MethodInfo generic = method.MakeGenericMethod(
new Type[] {
   myCollection.GetType(),
   myObject.GetType()
});

Once that's done, you need to call the Invoke method as mentioned above.

generic.Invoke(null, new object[] { csvData });

And you're done. Works a charm!

UPDATE:

As @Bevan highlighted, I do not need to create an array when calling the MakeGenericMethod function as it takes in params and I do not need to create an object in order to get the types as I can just pass the types directly to this function. In my case, since I have the types predefined in another class, I simply changed my code to:

object myCollection = null;

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

MethodInfo generic = method.MakeGenericMethod(
   myClassInfo.CollectionType,
   myClassInfo.ObjectType
);

myCollection = generic.Invoke(null, new object[] { csvData });

myClassInfo contains 2 properties of type Type which I set at run time based on an enum value passed to the constructor and will provide me with the relevant types which I then use in the MakeGenericMethod.

Thanks again for highlighting this @Bevan.

According to Github API two empty lines are a new paragraph (same as here in stackoverflow)

You can test it with http://prose.io

That's a bit to the side but do you really need nested dictionaries? Depending on the problem, sometimes flat dictionary may suffice... and look good at it:

>>> dict1 = {('level1','level2','levelA'): 0}
>>> dict1['level1','level2','levelB'] = 1
>>> update = {('level1','level2','levelB'): 10}
>>> dict1.update(update)
>>> print dict1
{('level1', 'level2', 'levelB'): 10, ('level1', 'level2', 'levelA'): 0}

You can run flutter clean.

But that's most likely a problem with your IDE or similar, as flutter run creates a brand new apk. And hot reload push only modifications.

Try running your app using the command line flutter run and then press r or R for respectively hot-reload and full-reload.

This is how to robustly do non-greedy matching of multi-character strings using sed. Lets say you want to change every foo...bar to <foo...bar> so for example this input:

$ cat file
ABC foo DEF bar GHI foo KLM bar NOP foo QRS bar TUV

should become this output:

ABC <foo DEF bar> GHI <foo KLM bar> NOP <foo QRS bar> TUV

To do that you convert foo and bar to individual characters and then use the negation of those characters between them:

$ sed 's/@/@A/g; s/{/@B/g; s/}/@C/g; s/foo/{/g; s/bar/}/g; s/{[^{}]*}/<&>/g; s/}/bar/g; s/{/foo/g; s/@C/}/g; s/@B/{/g; s/@A/@/g' file
ABC <foo DEF bar> GHI <foo KLM bar> NOP <foo QRS bar> TUV

In the above:

1. s/@/@A/g; s/{/@B/g; s/}/@C/g is converting { and } to placeholder strings that cannot exist in the input so those chars then are available to convert foo and bar to.
2. s/foo/{/g; s/bar/}/g is converting foo and bar to { and } respectively
3. s/{[^{}]*}/<&>/g is performing the op we want - converting foo...bar to <foo...bar>
4. s/}/bar/g; s/{/foo/g is converting { and } back to foo and bar.
5. s/@C/}/g; s/@B/{/g; s/@A/@/g is converting the placeholder strings back to their original characters.

Note that the above does not rely on any particular string not being present in the input as it manufactures such strings in the first step, nor does it care which occurrence of any particular regexp you want to match since you can use {[^{}]*} as many times as necessary in the expression to isolate the actual match you want and/or with seds numeric match operator, e.g. to only replace the 2nd occurrence:

$ sed 's/@/@A/g; s/{/@B/g; s/}/@C/g; s/foo/{/g; s/bar/}/g; s/{[^{}]*}/<&>/2; s/}/bar/g; s/{/foo/g; s/@C/}/g; s/@B/{/g; s/@A/@/g' file
ABC foo DEF bar GHI <foo KLM bar> NOP foo QRS bar TUV

Simple solution to achieve "split in two" background:

background: linear-gradient(to left, #ff0000 50%, #0000ff 50%);

You can also use degrees as direction

background: linear-gradient(80deg, #ff0000 50%, #0000ff 50%);

FYI this kind of code works (you can find it ugly, it is your right :) ) :

def list = null
list.each { println it }
soSomething()

In other words, this code has null/empty checks both useless:

if (members && !members.empty) {
    members.each { doAnotherThing it }
}

def doAnotherThing(def member) {
  // Some work
}

Try below code

    String dateStr = "Jul 27, 2011 8:35:29 PM";
    DateFormat readFormat = new SimpleDateFormat( "MMM dd, yyyy hh:mm:ss aa");
    DateFormat writeFormat = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss");
    Date date = null;
    try {
       date = readFormat.parse( dateStr );
    } catch ( ParseException e ) {
        e.printStackTrace();
    }

    String formattedDate = "";
    if( date != null ) {
    formattedDate = writeFormat.format( date );
    }

    System.out.println(formattedDate);

Good Luck!!!

Check for various formats.

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

You can use case in update and SWAP as many as you want

update Table SET column=(case when is_row_1 then value_2 else value_1 end) where rule_to_match_swap_columns

You need to include the getters and setters for all the fields that have been defined in the model Test class --

public class Test implements Serializable {

    private static final long serialVersionUID = -1764970284520387975L;

    public String name;

    public Test() {

    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

You don't need jQuery for this. Here's a simple working example:

<!DOCTYPE html>
<html>
    <head>
        <title>box-shadow-experiment</title>
        <style type="text/css">
            #box-shadow-div{
                position: fixed;
                width: 1px;
                height: 1px;
                border-radius: 100%;
                background-color:black;
                box-shadow: 0 0 10px 10px black;
                top: 49%;
                left: 48.85%;
            }
        </style>
        <script type="text/javascript">
            window.onload = function(){
                var bsDiv = document.getElementById("box-shadow-div");
                var x, y;
    // On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
                window.addEventListener('mousemove', function(event){
                    x = event.clientX;
                    y = event.clientY;                    
                    if ( typeof x !== 'undefined' ){
                        bsDiv.style.left = x + "px";
                        bsDiv.style.top = y + "px";
                    }
                }, false);
            }
        </script>
    </head>
    <body>
        <div id="box-shadow-div"></div>
    </body>
</html>

I chose position: fixed; so scrolling wouldn't be an issue.

This will copy to the immediate sub-directories, if you want to go deeper, adjust the -maxdepth parameter.

find . -mindepth 1 -maxdepth 1 -type d| xargs -n 1 cp -i index.html

If you don't want to copy to all directories, hopefully you can filter the directories you are not interested in. Example copying to all folders starting with a

find . -mindepth 1 -maxdepth 1 -type d| grep \/a |xargs -n 1 cp -i index.html

If copying to a arbitrary/disjoint set of directories you'll need Robert Gamble's suggestion.

You can use this one check:

create or replace function to_n(c varchar2) return number is
begin return to_number(c);
exception when others then return -123456;
end;

select id, n from t where to_n(n) = -123456;

<form id="my-form">
    <input type="text" name="in" value="some data" />
    <button type="submit">Go</button>
</form>

In JS:

function processForm(e) {
    if (e.preventDefault) e.preventDefault();

    /* do what you want with the form */

    // You must return false to prevent the default form behavior
    return false;
}

var form = document.getElementById('my-form');
if (form.attachEvent) {
    form.attachEvent("submit", processForm);
} else {
    form.addEventListener("submit", processForm);
}

Edit: in my opinion, this approach is better than setting the onSubmit attribute on the form since it maintains separation of mark-up and functionality. But that's just my two cents.

Edit2: Updated my example to include preventDefault()

In your test code your are trying to pass App to the spyOn function, but spyOn will only work with objects, not classes. Generally you need to use one of two approaches here:

1) Where the click handler calls a function passed as a prop, e.g.

class App extends Component {

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.props.someCallback();
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now pass in a spy function as a prop to the component, and assert that it is called:

describe('my sweet test', () => {
 it('clicks it', () => {
    const spy = jest.fn();
    const app = shallow(<App someCallback={spy} />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(spy).toHaveBeenCalled()
 })
})

2) Where the click handler sets some state on the component, e.g.

class App extends Component {
  state = {
      aProperty: 'first'
  }

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.setState({
          aProperty: 'second'
      });
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now make assertions about the state of the component, i.e.

describe('my sweet test', () => {
 it('clicks it', () => {
    const app = shallow(<App />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(app.state('aProperty')).toEqual('second');
 })
})

Beware of spaces in the values. I could be wrong, but I think spaces in the comma-separated list are not truncated using @Value and Spel. The list

foobar=a, b, c

would be read in as a list of strings

"a", " b", " c"

In most cases you would probably not want the spaces!

The expression

@Value("#{'${foobar}'.trim().replaceAll(\"\\s*(?=,)|(?<=,)\\s*\", \"\").split(',')}")
private List<String> foobarList;

would give you a list of strings:

"a", "b", "c".

The regular expression removes all spaces just before and just after a comma. Spaces inside of the values are not removed. So

foobar = AA, B B, CCC

should result in values

"AA", "B B", "CCC".

A bit old, but I was still getting the same SettingWithCopyWarning. Here was my solution:

df.loc[:, 'quantity'] = df['quantity'] * -1

In later Elasticsearch versions (7.x), types were removed. Updating a mapping can becomes:

curl -XPUT "http://localhost:9200/test/_mapping" -H 'Content-Type: application/json' -d'{
  "properties": {
    "new_geo_field": {
      "type": "geo_point"
    }
  }
}'

As others have pointed out, if the field exists, you typically have to reindex. There are exceptions, such as adding a new sub-field or changing analysis settings.

You can't "create a mapping", as the mapping is created with the index. Typically, you'd define the mapping when creating the index (or via index templates):

curl -XPUT "http://localhost:9200/test" -H 'Content-Type: application/json' -d'{
  "mappings": {
    "properties": {
      "foo_field": {
        "type": "text"
      }
    }
  }
}'

That's because, in production at least, you'd want to avoid letting Elasticsearch "guess" new fields. Which is what generated this question: geo data was read as an array of long values.

...5+ years later, I strongly suggest using date-fns instead

import endOfDayfrom 'date-fns/endOfDay'
import startOfDay from 'date-fns/startOfDay'

MyModel.find({
  createdAt: {
    $gte: startOfDay(new Date()),
    $lte: endOfDay(new Date())
  }
})

For those of us using Moment.js

const moment = require('moment')

const today = moment().startOf('day')

MyModel.find({
  createdAt: {
    $gte: today.toDate(),
    $lte: moment(today).endOf('day').toDate()
  }
})

Important: all moments are mutable!

tomorrow = today.add(1, 'days') does not work since it also mutates today. Calling moment(today) solves that problem by implicitly cloning today.

ngModel usually use for input tags for bind a variable that we can change variable from controller and html page but ngBind use for display a variable in html page and we can change variable just from controller and html just show variable.

Let's start with the uncomfortable truth: GWT compiler performance is really lousy. You can use some hacks here and there, but you're not going to get significantly better performance.

A nice performance hack you can do is to compile for only specific browsers, by inserting the following line in your gwt.xml:

<define-property name="user.agent" values="ie6,gecko,gecko1_8"></define-property>

or in gwt 2.x syntax, and for one browser only:

<set-property name="user.agent" value="gecko1_8"/>

This, for example, will compile your application for IE and FF only. If you know you are using only a specific browser for testing, you can use this little hack.

Another option: if you are using several locales, and again using only one for testing, you can comment them all out so that GWT will use the default locale, this shaves off some additional overhead from compile time.

Bottom line: you're not going to get order-of-magnitude increase in compiler performance, but taking several relaxations, you can shave off a few minutes here and there.

Inner join matches tables on keys, but outer join matches keys just for one side. For example when you use left outer join the query brings the whole left side table and matches the right side to the left table primary key and where there is not matched places null.

My answer is not exactly what is asked in the question. Rather I am giving a solution exactly how easily we can read a file into out java application from our project class path.

For example suppose a config file name example.xml is located in a path like below:-

com.myproject.config.dev

and our java executable class file is in the below path:-

com.myproject.server.main

now just check in both the above path which is the nearest common directory/folder from where you can access both dev and main directory/folder (com.myproject.server.main - where our application’s java executable class is existed) – We can see that it is myproject folder/directory which is the nearest common directory/folder from where we can access our example.xml file. Therefore from a java executable class resides in folder/directory main we have to go back two steps like ../../ to access myproject. Now following this, see how we can read the file:-

package com.myproject.server.main;

class Example {

  File xmlFile;

  public Example(){
       String filePath = this.getClass().getResource("../../config/dev/example.xml").getPath();
       this.xmlFile = new File(filePath);
    }

  public File getXMLFile() {
      return this.xmlFile;
  }
   public static void main(String args[]){
      Example ex = new Example();
      File xmlFile = ex.getXMLFile();
   }
}

Do you have a local user.name or user.email that's overriding the global one?

git config --list --global | grep user
  user.name=YOUR NAME
  user.email=YOUR@EMAIL
git config --list --local | grep user
  user.name=YOUR NAME
  user.email=

If so, remove them

git config --unset --local user.name
git config --unset --local user.email

The local settings are per-clone, so you'll have to unset the local user.name and user.email for each of the repos on your machine.

Basically you can't.

Version 1.52.1 none of the above worked.

Step 1: setAdapter to your listview.

 listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, GENRES)); 

Step 2: set choice mode for listview .The second line of below code represents which checkbox should be checked.

listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setItemChecked(2, true);

listView.setOnItemClickListener(this);



 private static  String[] GENRES = new String[] {
        "Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama",
        "Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller"
    };

Step 3: Checked views are returned in SparseBooleanArray, so you might use the below code to get key or values.The below sample are simply displayed selected names in a single String.

@Override
    public void onItemClick(AdapterView<?> adapter, View arg1, int arg2, long arg3)
    {

    SparseBooleanArray sp=getListView().getCheckedItemPositions();

    String str="";
    for(int i=0;i<sp.size();i++)
    {
        str+=GENRES[sp.keyAt(i)]+",";
    }
    Toast.makeText(this, ""+str, Toast.LENGTH_SHORT).show();

    }

The HTML

<a href="#" id="btn">click</a>

And the javascript

// get a cross-browser function for adding events, place this in [global] or somewhere you can access it
var on = (function(){
    if (window.addEventListener) {
        return function(target, type, listener){
            target.addEventListener(type, listener, false);
        };
    }
    else {
        return function(object, sEvent, fpNotify){
            object.attachEvent("on" + sEvent, fpNotify);
        };
    }
}());

// find the element
var el = document.getElementById("btn");

// add the first listener
on(el, "click", function(){
    alert("foo");
});

// add the second listener
on(el, "click", function(){
    alert("bar");
});

This will alert both 'foo' and 'bar' when clicked.
