jQuery ui 1.9 is going to take care of this for you. Heres a demo of the pre:

https://dl.dropbox.com/u/3872624/lab/touch/index.html

Just grab the jquery.mouse.ui.js out, stick it under the jQuery ui file you're loading, and that's all you should have to do! Works for sortable as well.

This code is working great for me, but if your getting errors, an updated version of jquery.mouse.ui.js can be found here:

Jquery-ui sortable doesn't work on touch devices based on Android or IOS

$(function () {
    $( ".droppable-area" ).sortable({
                connectWith: ".connected-sortable",
                containment: ".droppable-area", //(parent div)
                stack: '.connected-sortable div'
            }).disableSelection();
});

I created a div element which has the same size as the image and is positioned on top of the image. Then, the mouse events do not go to the image element.

This may be helpful for some one :

In my case i was able to remove this error by first loading the js files on which draggable depends. They were ui.mouse.js, ui.core and ui.widget i.e UI Core Widget Factory Mouse Interaction

Make sure the script tag for loading dependencies lies above the draggable js loading tag.

$("#myModal").draggable({
    handle: ".modal-header"
}); 

it works for me. I got it from there. if you give me thanks please give 70% to Andres Ilich

Here is my simple version.
The function draggable takes a jQuery object as argument.

/**
 * @param {jQuery} elem
 */
function draggable(elem){

    elem.mousedown(function(evt){
        var x = parseInt(this.style.left || 0) - evt.pageX;
        var y = parseInt(this.style.top || 0) - evt.pageY;

        elem.mousemove(function(evt){
            elem.css('left', x + evt.pageX);
            elem.css('top', y + evt.pageY);
        });
    });

    elem.mouseup(off);
    elem.mouseleave(off);

    function off(){
        elem.off("mousemove");
    }
}

<?php
   header("Location: your url");
   exit;
?>

This is not a matter of accuracy, nor is it a matter of precision. It is a matter of meeting the expectations of humans who use base 10 for calculations instead of base 2. For example, using doubles for financial calculations does not produce answers that are "wrong" in a mathematical sense, but it can produce answers that are not what is expected in a financial sense.

Even if you round off your results at the last minute before output, you can still occasionally get a result using doubles that does not match expectations.

Using a calculator, or calculating results by hand, 1.40 * 165 = 231 exactly. However, internally using doubles, on my compiler / operating system environment, it is stored as a binary number close to 230.99999... so if you truncate the number, you get 230 instead of 231. You may reason that rounding instead of truncating would have given the desired result of 231. That is true, but rounding always involves truncation. Whatever rounding technique you use, there are still boundary conditions like this one that will round down when you expect it to round up. They are rare enough that they often will not be found through casual testing or observation. You may have to write some code to search for examples that illustrate outcomes that do not behave as expected.

Assume you want to round something to the nearest penny. So you take your final result, multiply by 100, add 0.5, truncate, then divide the result by 100 to get back to pennies. If the internal number you stored was 3.46499999.... instead of 3.465, you are going to get 3.46 instead 3.47 when you round the number to the nearest penny. But your base 10 calculations may have indicated that the answer should be 3.465 exactly, which clearly should round up to 3.47, not down to 3.46. These kinds of things happen occasionally in real life when you use doubles for financial calculations. It is rare, so it often goes unnoticed as an issue, but it happens.

If you use base 10 for your internal calculations instead of doubles, the answers are always exactly what is expected by humans, assuming no other bugs in your code.

Here are the CASE statement examples from the PostgreSQL docs (Postgres follows the SQL standard here):

SELECT a,
   CASE WHEN a=1 THEN 'one'
        WHEN a=2 THEN 'two'
        ELSE 'other'
   END
FROM test;

or

SELECT a,
   CASE a WHEN 1 THEN 'one'
          WHEN 2 THEN 'two'
          ELSE 'other'
   END
FROM test;

Obviously the second form is cleaner when you are just checking one field against a list of possible values. The first form allows more complicated expressions.

Git pull combines two actions -- fetching new commits from the remote repository in the tracked branches and then merging them into your current branch.

When you checked out a particular commit, you don't have a current branch, you only have HEAD pointing to the last commit you made. So git pull doesn't have all its parameters specified. That's why it didn't work.

Based on your updated info, what you're trying to do is revert your remote repo. If you know the commit that introduced the bug, the easiest way to handle this is with git revert which records a new commit which undoes the specified buggy commit:

$ git checkout master
$ git reflog            #to find the SHA1 of buggy commit, say  b12345
$ git revert b12345
$ git pull
$ git push

Since it's your server that you are wanting to change, I will assume that you don't need to rewrite history to hide the buggy commit.

If the bug was introduced in a merge commit, then this procedure will not work. See How-to-revert-a-faulty-merge.

In my case it was caused by align_parentBottom="true" given to a view inside a RelativeLayout. Removed all the alignParentBottom's and changed all the layouts to vertical LinearLayouts and problem gone.

This error comes because compile does not know where to find the class..so it occurs mainly when u copy or import item ..to solve this .. 1.change the namespace in the formname.cs and formname.designer.cs to the name of your project .

If you want to build your solution for x86 and x64, your solution must be configured for both platforms. Actually you just have an Any CPU configuration.

How to check the available configuration for a project

To check the available configuration for a given project, open the project file (*.csproj for example) and look for a PropertyGroup with the right Condition.

If you want to build in Release mode for x86, you must have something like this in your project file:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
  ...
</PropertyGroup>

To Understand the difference, one needs to to understand that "the godfather" paradigm of both procedural and functional programming is the imperative programming.

Basically procedural programming is merely a way of structuring imperative programs in which the primary method of abstraction is the "procedure." (or "function" in some programming languages). Even Object Oriented Programming is just another way of structuring an imperative program, where the state is encapsulated in objects, becoming an object with a "current state," plus this object has a set of functions, methods, and other stuff that let you the programmer manipulate or update the state.

Now, in regards to functional programming, the gist in its approach is that it identifies what values to take and how these values should be transferred. (so there is no state, and no mutable data as it takes functions as first class values and pass them as parameters to other functions).

PS: understanding every programming paradigm is used for should clarify the differences between all of them.

PSS: In the end of the day, programming paradigms are just different approaches to solving problems.

PSS: this quora answer has a great explanation.

Another thumb rule is to check where const is:

1. before * => value stored is constant
2. after * => pointer itself is constant

The compiler needs to know the size of the second dimension in your two dimensional array. For example:

void print_graph(g_node graph_node[], double weight[][5], int nodes);

cout << text << " " << i << endl;

The terminology is a bit confusing indeed, but both javax.net.ssl.keyStore and javax.net.ssl.trustStore are used to specify which keystores to use, for two different purposes. Keystores come in various formats and are not even necessarily files (see this question), and keytool is just a tool to perform various operations on them (import/export/list/...).

The javax.net.ssl.keyStore and javax.net.ssl.trustStore parameters are the default parameters used to build KeyManagers and TrustManagers (respectively), then used to build an SSLContext which essentially contains the SSL/TLS settings to use when making an SSL/TLS connection via an SSLSocketFactory or an SSLEngine. These system properties are just where the default values come from, which is then used by SSLContext.getDefault(), itself used by SSLSocketFactory.getDefault() for example. (All of this can be customized via the API in a number of places, if you don't want to use the default values and that specific SSLContexts for a given purpose.)

The difference between the KeyManager and TrustManager (and thus between javax.net.ssl.keyStore and javax.net.ssl.trustStore) is as follows (quoted from the JSSE ref guide):

TrustManager: Determines whether the remote authentication credentials (and thus the connection) should be trusted.

KeyManager: Determines which authentication credentials to send to the remote host.

(Other parameters are available and their default values are described in the JSSE ref guide. Note that while there is a default value for the trust store, there isn't one for the key store.)

Essentially, the keystore in javax.net.ssl.keyStore is meant to contain your private keys and certificates, whereas the javax.net.ssl.trustStore is meant to contain the CA certificates you're willing to trust when a remote party presents its certificate. In some cases, they can be one and the same store, although it's often better practice to use distinct stores (especially when they're file-based).

WSDL: Stands for Web Service Description Language

In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL files. For example you cannot use same file for .Net and php client. The WSDL file has some descriptions about web service functions. The type of this file is XML. SOAP is an alternative for REST.

REST: Stands for Representational State Transfer

It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL files. The CRUD operation can be implemented by different HTTP Verbs(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP protocol and most of times the response is in JSON or XML format. On the other hand the client application have to exactly call the related HTTP Verb via exact parameters names and types. Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.

SOA: Stands for Service Oriented Architecture

Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time. Both REST and SOAP web services are kind of SOA.

JSON: Stands for javascript Object Notation

when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :

class Human{
 string Name;
 string Family;
 int Age;
}

and you have some instances from this class :

Human h1 = new Human(){
  Name='Saman',
  Family='Gholami',
  Age=26
}

when you serialize the h1 object to JSON the result is :

  [h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]

javascript can evaluate this format by eval() function and make an associative array from this JSON string. This one is different concept in comparison to other concepts I described formerly.

The headers are entirely encrypted. The only information going over the network 'in the clear' is related to the SSL setup and D/H key exchange. This exchange is carefully designed not to yield any useful information to eavesdroppers, and once it has taken place, all data is encrypted.

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

Add vertical-align: middle; to the td element that contains the button

<td style="vertical-align:middle;">  <--add this to center vertically
  <a href="#" class="btn btn-primary">
    <i class="icon-check icon-white"></i>
  </a>
</td>

For the sake of completeness: you can also use the sortByCol() function from the BBmisc package:

library(BBmisc)
sortByCol(dd, c("z", "b"), asc = c(FALSE, TRUE))
    b x y z
4 Low C 9 2
2 Med D 3 1
1  Hi A 8 1
3  Hi A 9 1

Performance comparison:

library(microbenchmark)
microbenchmark(sortByCol(dd, c("z", "b"), asc = c(FALSE, TRUE)), times = 100000)
median 202.878

library(plyr)
microbenchmark(arrange(dd,desc(z),b),times=100000)
median 148.758

microbenchmark(dd[with(dd, order(-z, b)), ], times = 100000)
median 115.872

Memory mapping has a potential for a huge speed advantage compared to traditional IO. It lets the operating system read the data from the source file as the pages in the memory mapped file are touched. This works by creating faulting pages, which the OS detects and then the OS loads the corresponding data from the file automatically.

This works the same way as the paging mechanism and is usually optimized for high speed I/O by reading data on system page boundaries and sizes (usually 4K) - a size for which most file system caches are optimized to.

What about something like this:

First resample the data frame into 1D intervals. This takes the mean of the values for all duplicate days. Use the fill_method option to fill in missing date values. Next, pass the resampled frame into pd.rolling_mean with a window of 3 and min_periods=1 :

pd.rolling_mean(df.resample("1D", fill_method="ffill"), window=3, min_periods=1)

df.resample("1d").sum().fillna(0).rolling(window=3, min_periods=1).mean()

Don't use SSL on port 465, it's been deprecated since 1998 and is only used by Microsoft products that didn't get the memo; use TLS on port 587 instead: So, the code below should work very well for you.

mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtp.gmail.com"; // SMTP server

$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the 

I had a similar problem -- no matter what I did I couldn't get the tabsize to stick at 2, even though it is in my user settings -- that ended up being due to the EditorConfig extension. It looks for a .editorconfig file in your current working directory and, if it doesn't find one (or the one it finds doesn't specify root=true), it will continue looking at parent directories until it finds one.

Turns out I had a .editorconfig in a parent directory of the dir I put all my new code projects in, and it specified a tabSize of 4. Deleting that file fixed my issue.

If you want to apply to all columns you can use:

df.apply(pd.value_counts)

This will apply a column based aggregation function (in this case value_counts) to each of the columns.

i would advice to create table with unique name before bulk inserting.

  kw=(EditText)findViewById(R.id.kw);
    btn=(Button)findViewById(R.id.btn);
    cost=(TextView )findViewById(R.id.cost);


            btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) { cst =  Double.valueOf(kw.getText().toString());
            cst = cst*0.551;
            cost.setText(cst.toString());
        }
    });

check the round function and how does the length argument works. It controls the behaviour of the precision of the result

you can use this code to scale image in required size.

+ (UIImage *)scaleImage:(UIImage *)image toSize:(CGSize)newSize
{
    CGSize actSize = image.size;
    float scale = actSize.width/actSize.height;

    if (scale < 1) {
        newSize.height = newSize.width/scale;
    } 
    else {
        newSize.width = newSize.height*scale;
    }

    UIGraphicsBeginImageContext(newSize);
    [image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

Try this:

sed -i 's/\s*$//' youfile.txt

This is a variation of the solution in the question that should be faster than what's in the question. It uses a static sieve of Eratosthenes with no other optimizations.

            primes.difference_update(set(list(range(i, limit + 1, i))[1:]))
    return sorted(primes)

An absolutely positioned element is actually positioned regarding a relative parent, or the nearest found relative parent. So the element with overflow: hidden should be between relative and absolute positioned elements:

<div class="relative-parent">
  <div class="hiding-parent">
    <div class="child"></div>
  </div>
</div>

.relative-parent {
  position:relative;
}
.hiding-parent {
  overflow:hidden;
}
.child {
  position:absolute; 
}

Late to the game, but I found this method is extremely intuitive. https://codepen.io/adamchenwei/pen/BRNxJr

I'm going to offer a terrible option here, since I have no idea how to do anything with git except add commit and push, here's how I "reverted" a subdirectory:

I started a new repository on my local pc, reverted the whole thing to the commit I wanted to copy code from and then copied those files over to my working directory, add commit push et voila. Don't hate the player, hate Mr Torvalds for being smarter than us all.

RegexBuddy is telling me if you want to include it at the beginning, this is the correct syntax:

"(?i)\\b(\\w+)\\b(\\s+\\1)+\\b"

In case you wonder, In Bootstrap templating system (which is very accurate), here is how they divide the columns when you apply the class .col-md-4 (1/3 of the 12 column system)

CSS

.col-md-4{
    float: left;
    width: 33.33333333%;
}

I'm not a fan of float, but if you really want your element to be perfectly 1/3 of your page, then you don't have a choice because sometimes when you use inline-block element, browser can consider space in your HTML as a 1px space which would break your perfect 1/3. Hope it helped !

Stumbled upon this question when was looking for fast, modern, platform independent and elegant solution. Didnt like any of above, cpp-netlib would be the winner but it has horrific memory vulnerability in "decoded" function. So I came up with boost's spirit qi/karma solution.

namespace bsq = boost::spirit::qi;
namespace bk = boost::spirit::karma;
bsq::int_parser<unsigned char, 16, 2, 2> hex_byte;
template <typename InputIterator>
struct unescaped_string
    : bsq::grammar<InputIterator, std::string(char const *)> {
  unescaped_string() : unescaped_string::base_type(unesc_str) {
    unesc_char.add("+", ' ');

    unesc_str = *(unesc_char | "%" >> hex_byte | bsq::char_);
  }

  bsq::rule<InputIterator, std::string(char const *)> unesc_str;
  bsq::symbols<char const, char const> unesc_char;
};

template <typename OutputIterator>
struct escaped_string : bk::grammar<OutputIterator, std::string(char const *)> {
  escaped_string() : escaped_string::base_type(esc_str) {

    esc_str = *(bk::char_("a-zA-Z0-9_.~-") | "%" << bk::right_align(2,0)[bk::hex]);
  }
  bk::rule<OutputIterator, std::string(char const *)> esc_str;
};

The usage of above as following:

std::string unescape(const std::string &input) {
  std::string retVal;
  retVal.reserve(input.size());
  typedef std::string::const_iterator iterator_type;

  char const *start = "";
  iterator_type beg = input.begin();
  iterator_type end = input.end();
  unescaped_string<iterator_type> p;

  if (!bsq::parse(beg, end, p(start), retVal))
    retVal = input;
  return retVal;
}

std::string escape(const std::string &input) {
  typedef std::back_insert_iterator<std::string> sink_type;
  std::string retVal;
  retVal.reserve(input.size() * 3);
  sink_type sink(retVal);

Just add a class of required to the select

<select id="select" class="required">

Following is worked for me

git reset HEAD

I was getting following error

git stash
src/config.php: needs merge
src/config.php: needs merge
src/config.php: unmerge(230a02b5bf1c6eab8adce2cec8d573822d21241d)
src/config.php: unmerged (f5cc88c0fda69bf72107bcc5c2860c3e5eb978fa)

Then i ran

git reset HEAD

it worked

The purpose is typically just to restrict the scope of the nested class. Nested classes compared to normal classes have the additional possibility of the private modifier (as well as protected of course).

Basically, if you only need to use this class from within the "parent" class (in terms of scope), then it is usually appropiate to define it as a nested class. If this class might need to be used from without the assembly/library, then it is usually more convenient to the user to define it as a separate (sibling) class, whether or not there is any conceptual relationship between the two classes. Even though it is technically possible to create a public class nested within a public parent class, this is in my opinion rarely an appropiate thing to implement.

For very large output logs it could be difficult to open (network delay, scrolling). This is the solution I'm using to check big log files:

    https://${URL}/jenkins/job/${jobName}/${buildNumber}/

in the left column you see: View as plain text. Do a right mouse click on it and choose save links as. Now you can save your big log as .txt file. Open it with notepad++ and you can go through your logs easily without network delays during scrolling.

I think assembly plugin puts the file on class path. The location will be different in in the JAR than you see on disk. Unpack the resulting JAR and look where the file is located there.

$elapsed = '2592000';
// Time in the past
$time_past = '2014-07-16 11:35:33';
$time_past = strtotime($time_past);

// Add a month to that time
$time_past = $time_past + $elapsed;

// Time NOW
$time_now = time();

// Check if its been a month since time past
if($time_past > $time_now){
    echo 'Hasnt been a month';    
}else{
    echo 'Been longer than a month';
}

If you need the construct for a quick example to play with, use the : operator.

But if you are creating a vector/range of numbers dynamically, then use seq() instead.

Let's say you are creating the vector/range of numbers from a to b with a:b, and you expect it to be an increasing series. Then, if b is evaluated to be less than a, you will get a decreasing sequence but you will never be notified about it, and your program will continue to execute with the wrong kind of input.

In this case, if you use seq(), you can set the sign of the by argument to match the direction of your sequence, and an error will be raised if they do not match. For example,

seq(a, b, -1)

will raise an error for a=2, b=6, because the coder expected a decreasing sequence.

At least the way I've done this is as follows:

If you have a nested src tree (say com.test.myclass.MyClass) and you are compiling from a root directory you need to do the following:

1) when you create the jar (usually put this in a script): jar -cvfm my.jar com/test/myclass/manifest.txt com/test/myclass/MyClass.class

2) The manifest should look like:

Mainfest-version: 1.0 Main-Class: com.test.myclass.MyClass Class-Path: . my.jar

3) Now you can run the jar from anywhere like this:

java -jar my.jar

Hope this helps someone

You'd need to use return values.

DECLARE @SelectedValue int

CREATE PROCEDURE GetMyInt (@MyIntField int OUTPUT)
AS
SELECT @MyIntField = MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1

Then you call it like this:

EXEC GetMyInt OUTPUT @SelectedValue

You can also create your own (if unhappy with the options available).

Creating your own Timer implementation is pretty basic stuff.

This is an example for an application that needed COM object access on the same thread as the rest of my codebase.

/// <summary>
/// Internal timer for window.setTimeout() and window.setInterval().
/// This is to ensure that async calls always run on the same thread.
/// </summary>
public class Timer : IDisposable {

    public void Tick()
    {
        if (Enabled && Environment.TickCount >= nextTick)
        {
            Callback.Invoke(this, null);
            nextTick = Environment.TickCount + Interval;
        }
    }

    private int nextTick = 0;

    public void Start()
    {
        this.Enabled = true;
        Interval = interval;
    }

    public void Stop()
    {
        this.Enabled = false;
    }

    public event EventHandler Callback;

    public bool Enabled = false;

    private int interval = 1000;

    public int Interval
    {
        get { return interval; }
        set { interval = value; nextTick = Environment.TickCount + interval; }
    }

    public void Dispose()
    {
        this.Callback = null;
        this.Stop();
    }

}

You can add events as follows:

Timer timer = new Timer();
timer.Callback += delegate
{
    if (once) { timer.Enabled = false; }
    Callback.execute(callbackId, args);
};
timer.Enabled = true;
timer.Interval = ms;
timer.Start();
Window.timers.Add(Environment.TickCount, timer);

To make sure the timer works you need to create an endless loop as follows:

while (true) {
     // Create a new list in case a new timer
     // is added/removed during a callback.
     foreach (Timer timer in new List<Timer>(timers.Values))
     {
         timer.Tick();
     }
}

As @Felix Kling suggested use action='store_true':

>>> from argparse import ArgumentParser
>>> p = ArgumentParser()
>>> _ = p.add_argument('-f', '--foo', action='store_true')
>>> args = p.parse_args()
>>> args.foo
False
>>> args = p.parse_args(['-f'])
>>> args.foo
True

var table = $('#myTableId').DataTable();
var a= [];
$.each(table.rows('.myClassName').data(), function() {
a.push(this["productId"]);
});

console.log(a[0]);

DevTools: [network] explain empty bars preceeding request

Investigated further and have identified that there's no significant difference between our Stalled and Queueing ranges. Both are calculated from the delta's of other timestamps, rather than provided from netstack or renderer.

---

Currently, if we're waiting for a socket to become available:

• we'll call it stalled if some proxy negotiation happened
• we'll call it queuing if no proxy/ssl work was required.

I think you will want to use ThreadSafeClientConnManager.

You can see how it works here: http://foo.jasonhudgins.com/2009/08/http-connection-reuse-in-android.html

Or in the AndroidHttpClient which uses it internally.

In your while statement just replace mysql_fetch_row with mysql_fetch_array or mysql_fetch_assoc... whichever works...

Other alternative:

JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
                                                String.class, "Your message");

Then:

System.out.println(element.getValue()); // Result: Your message

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

Enabling SQL Server Service Broker requires a database lock. Stop the SQL Server Agent and then execute the following:

USE master ;
GO

ALTER DATABASE [MyDatabase] SET ENABLE_BROKER ;
GO

Change [MyDatabase] with the name of your database in question and then start SQL Server Agent.

If you want to see all the databases that have Service Broker enabled or disabled, then query sys.databases, for instance:

SELECT
    name, database_id, is_broker_enabled
FROM sys.databases

Is there a prize for being lazy and using the transpose function of NumPy arrays? ;)

import numpy as np

a = np.array([(1,2,3), (4,5,6)])

b = a.transpose()

Google play finds you as developer via your keystore.

and maybe your country IP is banned on Google when you generate your new keystore.

change your IP Address and generate new keystore, the problem will be fixed.

if you didn't succeed, use another Gmail in Android Studio and generate new keystore.

console.log("my object: %o", myObj)

Otherwise you'll end up with a string representation sometimes displaying:

[object Object]

or some such.

By itself, document.activeElement can still return an element if the document isn't focused (and thus nothing in the document is focused!)

You may want that behavior, or it may not matter (e.g. within a keydown event), but if you need to know something is actually focused, you can additionally check document.hasFocus().

The following will give you the focused element if there is one, or else null.

var focused_element = null;
if (
    document.hasFocus() &&
    document.activeElement !== document.body &&
    document.activeElement !== document.documentElement
) {
    focused_element = document.activeElement;
}

To check whether a specific element has focus, it's simpler:

var input_focused = document.activeElement === input && document.hasFocus();

To check whether anything is focused, it's more complex again:

var anything_is_focused = (
    document.hasFocus() &&
    document.activeElement !== null &&
    document.activeElement !== document.body &&
    document.activeElement !== document.documentElement
);

Robustness Note: In the code where it the checks against document.body and document.documentElement, this is because some browsers return one of these or null when nothing is focused.

It doesn't account for if the <body> (or maybe <html>) had a tabIndex attribute and thus could actually be focused. If you're writing a library or something and want it to be robust, you should probably handle that somehow.

Here's a (heavy airquotes) "one-liner" version of getting the focused element, which is conceptually more complicated because you have to know about short-circuiting, and y'know, it obviously doesn't fit on one line, assuming you want it to be readable.
I'm not gonna recommend this one. But if you're a 1337 hax0r, idk... it's there.
You could also remove the || null part if you don't mind getting false in some cases. (You could still get null if document.activeElement is null):

var focused_element = (
    document.hasFocus() &&
    document.activeElement !== document.body &&
    document.activeElement !== document.documentElement &&
    document.activeElement
) || null;

For checking if a specific element is focused, alternatively you could use events, but this way requires setup (and potentially teardown), and importantly, assumes an initial state:

var input_focused = false;
input.addEventListener("focus", function() {
    input_focused = true;
});
input.addEventListener("blur", function() {
    input_focused = false;
});

You could fix the initial state assumption by using the non-evented way, but then you might as well just use that instead.

So I did some tests with sqlite for very large files, and came to some conclusions (at least for my specific application).

The tests involve a single sqlite file with either a single table, or multiple tables. Each table had about 8 columns, almost all integers, and 4 indices.

The idea was to insert enough data until sqlite files were about 50GB.

Single Table

I tried to insert multiple rows into a sqlite file with just one table. When the file was about 7GB (sorry I can't be specific about row counts) insertions were taking far too long. I had estimated that my test to insert all my data would take 24 hours or so, but it did not complete even after 48 hours.

This leads me to conclude that a single, very large sqlite table will have issues with insertions, and probably other operations as well.

I guess this is no surprise, as the table gets larger, inserting and updating all the indices take longer.

Multiple Tables

I then tried splitting the data by time over several tables, one table per day. The data for the original 1 table was split to ~700 tables.

This setup had no problems with the insertion, it did not take longer as time progressed, since a new table was created for every day.

Vacuum Issues

As pointed out by i_like_caffeine, the VACUUM command is a problem the larger the sqlite file is. As more inserts/deletes are done, the fragmentation of the file on disk will get worse, so the goal is to periodically VACUUM to optimize the file and recover file space.

However, as pointed out by documentation, a full copy of the database is made to do a vacuum, taking a very long time to complete. So, the smaller the database, the faster this operation will finish.

Conclusions

For my specific application, I'll probably be splitting out data over several db files, one per day, to get the best of both vacuum performance and insertion/delete speed.

This complicates queries, but for me, it's a worthwhile tradeoff to be able to index this much data. An additional advantage is that I can just delete a whole db file to drop a day's worth of data (a common operation for my application).

I'd probably have to monitor table size per file as well to see when the speed will become a problem.

It's too bad that there doesn't seem to be an incremental vacuum method other than auto vacuum. I can't use it because my goal for vacuum is to defragment the file (file space isn't a big deal), which auto vacuum does not do. In fact, documentation states it may make fragmentation worse, so I have to resort to periodically doing a full vacuum on the file.

it should works at least in pyspark 2.4

tdata = tdata.withColumn("Age",  when((tdata.Age == "") & (tdata.Survived == "0") , "NewValue").otherwise(tdata.Age))

The main difference is that with a = a + b, there is no typecasting going on, and so the compiler gets angry at you for not typecasting. But with a += b, what it's really doing is typecasting b to a type compatible with a. So if you do

int a=5;
long b=10;
a+=b;
System.out.println(a);

What you're really doing is:

int a=5;
long b=10;
a=a+(int)b;
System.out.println(a);

RETURNING

Since PostgreSQL 8.2, that's possible with a single round-trip to the database:

INSERT INTO tbl(filename)
VALUES ('my_filename')
RETURNING tbl_id;

tbl_id would typically be a serial or IDENTITY (Postgres 10 or later) column. More in the manual.

Explicitly fetch value

If filename needs to include tbl_id (redundantly), you can still use a single query.

Use lastval() or the more specific currval():

INSERT INTO tbl (filename)
VALUES ('my_filename' || currval('tbl_tbl_id_seq')   -- or lastval()
RETURNING tbl_id;

See:

• Reference value of serial column in another column during same INSERT

If multiple sequences may be advanced in the process (even by way of triggers or other side effects) the sure way is to use currval('tbl_tbl_id_seq').

Name of sequence

The string literal 'tbl_tbl_id_seq' in my example is supposed to be the actual name of the sequence and is cast to regclass, which raises an exception if no sequence of that name can be found in the current search_path.

tbl_tbl_id_seq is the automatically generated default for a table tbl with a serial column tbl_id. But there are no guarantees. A column default can fetch values from any sequence if so defined. And if the default name is taken when creating the table, Postgres picks the next free name according to a simple algorithm.

If you don't know the name of the sequence for a serial column, use the dedicated function pg_get_serial_sequence(). Can be done on the fly:

INSERT INTO tbl (filename)
VALUES ('my_filename' || currval(pg_get_serial_sequence('tbl', 'tbl_id'))
RETURNING tbl_id;

According to the API, the headers can all be passed in using requests.get:

import requests
r=requests.get("http://www.example.com/", headers={"content-type":"text"})

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

So before MySQL 8.0 there is no ROW_NUMBER() function. Accpted answer rewritten to support older versions of MySQL:

SET @row_number = 0;
SELECT t.A, t.B, t.C, (@row_number:=@row_number + 1) AS number
FROM dbo.tableZ AS t ORDER BY t.A;

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

$(selector).change()

.change()

.trigger("change")

Longer slower alternative, better for abstraction.

.trigger("change")

$(selector).trigger("change")

Have you tried creating a windows shortcut for sql plus and set the working directory?

When going the other way (hasMany):

User::with(array('post'=>function($query){
    $query->select('id','user_id');
}))->get();

Don't forget to include the foreign key (assuming it is user_id in this example) to resolve the relationship, otherwise you'll get zero results for your relation.

If you want to see the full paths, I would recommend to cd to the top directory (of your drive if using windows)

cd C:\
grep -r somethingtosearch C:\Users\Ozzesh\temp

Or on Linux:

cd /
grep -r somethingtosearch ~/temp

if you really resist on your file name filtering (*.log) AND you want recursive (files are not all in the same directory), combining find and grep is the most flexible way:

cd /
find ~/temp -iname '*.log' -type f -exec grep somethingtosearch '{}' \;

GitHub for Windows on Windows 7 currently installs Git in a path similar to this:

C:\Users\{username}\AppData\Local\GitHub\PortableGit_93e8418133eb85e81a81e5e19c272776524496c6\bin\git.exe

The guid after PortableGit_ may well be different on your system.

In my solution, i have

$scope.uploadVideo = function(){
    var uploadUrl = "/api/uploadEvent";


    //obj with data, that can be one input or form
    file = $scope.video;
    var fd = new FormData();


    //check file form on being
    for (var obj in file) {
        if (file[obj] || file[obj] == 0) {
            fd.append(obj, file[obj]);
        }
    }

    //open XHR request
    var xhr = new XMLHttpRequest();


    // $apply to rendering progress bar for any chunking update
    xhr.upload.onprogress = function(event) {
        $scope.uploadStatus = {
            loaded: event.loaded,
            total:  event.total
        };
        $scope.$apply();
    };

    xhr.onload = xhr.onerror = function(e) {
        if (this.status == 200 || this.status == 201) {

            //sucess

            $scope.uploadStatus = {
                loaded: 0,
                total:  0
            };


            //this is for my solution
            $scope.video = {};
            $scope.vm.model.push(JSON.parse(e.currentTarget.response));
            $scope.$apply();

        } else {
           //on else status
        }
    };

    xhr.open("POST", uploadUrl, true);

    //token for upload, thit for my solution
    xhr.setRequestHeader("Authorization", "JWT " + window.localStorage.token);


    //send
    xhr.send(fd); 
};

}

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

You can use the HTML5 <mark> tag.

HTML:

<h1><mark>The Last Will and Testament of Eric Jones</mark></h1>

CSS:

mark
{
    background-color: green;
}

This works great on win7

$ PATH=$PATH:/c/Python27/ $ python -V Python 2.7.12

If you have an interface in your controller

public myController(IXInterface Xinstance){}

You must register them to Dependency Injection container.

container.Bind<IXInterface>().To<XClass>().InRequestScope();

When you want to use pure Markdown (without nested HTML), you can use Emojis to draw attention to some fragment of the file, i.e. ??WARNING??, IMPORTANT? or NEW.

The shortest way is to directly add the below code as additional attributes in the input type that you want to change.

onfocus="if(this.value=='Search')this.value=''" 
onblur="if(this.value=='')this.value='Search'"

Please note: Change the text "Search" to "go" or any other text to suit your requirements.

just add

android:gravity="center"

and done :)

Let consider that your data are in the file values.txt and that you want to import them in the database table myTable then the following query does the job

COPY myTable FROM 'value.txt' (DELIMITER('|'));

https://www.postgresql.org/docs/current/static/sql-copy.html

The C5 Generic Collections Library classes all support the AddRange method. C5 has a much more robust interface that actually exposes all of the features of its underlying implementations and is interface-compatible with the System.Collections.Generic ICollection and IList interfaces, meaning that C5's collections can be easily substituted as the underlying implementation.

For space-character removal use

"hello world".replace(/\s/g, "");

for all white space use the suggestion by Rocket in the comments below!

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

Option 2 is correct.

The nested list should be inside a <li> element of the list in which it is nested.

Link to the W3C Wiki on Lists (taken from comment below): HTML Lists Wiki.

Link to the HTML5 W3C ul spec: HTML5 ul. Note that a ul element may contain exactly zero or more li elements. The same applies to HTML5 ol. The description list (HTML5 dl) is similar, but allows both dt and dd elements.

More Notes:

• dl = definition list.
• ol = ordered list (numbers).
• ul = unordered list (bullets).

If you want to get started with Java, you will be much happier with a Java IDE. IntelliJ Community Edition, Eclipse, and Netbeans are all free.

I know IntelliJ can be set to use Visual Studio keyboard shortcuts, so even if you are a keyboard junkie like myself, you won't feel out of place in a Java IDE.

The differences in IDEs are minimal, and the time you will save by using a Java IDE for Java development will be huge.

Good luck!

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

Another solution would be to use higher-order functions as follows

opt.<Runnable>map(value -> () -> System.out.println("Found " + value))
   .orElse(() -> System.out.println("Not Found"))
   .run();

If you know you don't have any whitespace in the input:

xargs chmod 755 < file.txt

If there might be whitespace in the paths, and if you have GNU xargs:

tr '\n' '\0' < file.txt | xargs -0 chmod 755

Why not using attribute "disabled" in css. This must works on all browsers.

button[disabled]:hover {
    background: red;
}
button:hover {
    background: lime;
}

Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

When the argument -Xss doesn't do the job try deleting the temporary files from:

c:\Users\{user}\AppData\Local\Temp\.

This did the trick for me.

A good alternative is this:

find . -type f | xargs chmod -v 644

and for directories:

find . -type d | xargs chmod -v 755

and to be more explicit:

find . -type f | xargs -I{} chmod -v 644 {}

It seems that, according to the HTML5 spec, the value property of the textarea element should return '\r\n' for a newline:

The element's value is defined to be the element's raw value with the following transformation applied:

Replace every occurrence of a "CR" (U+000D) character not followed by a "LF" (U+000A) character, and every occurrence of a "LF" (U+000A) character not preceded by a "CR" (U+000D) character, by a two-character string consisting of a U+000D CARRIAGE RETURN "CRLF" (U+000A) character pair.

Following the link to 'value' makes it clear that it refers to the value property accessed in javascript:

Form controls have a value and a checkedness. (The latter is only used by input elements.) These are used to describe how the user interacts with the control.

However, in all five major browsers (using Windows, 11/27/2015), if '\r\n' is written to a textarea, the '\r' is stripped. (To test: var e=document.createElement('textarea'); e.value='\r\n'; alert(e.value=='\n');) This is true of IE since v9. Before that, IE was returning '\r\n' and converting both '\r' and '\n' to '\r\n' (which is the HTML5 spec). So... I'm confused.

To be safe, it's usually enough to use '\r?\n' in regular expressions instead of just '\n', but if the newline sequence must be known, a test like the above can be performed in the app.

If you have pip install and you want to see what packages have been installed with your installer tools you can simply call this:

pip freeze

It will also include version numbers for the installed packages.

Update

pip has been updated to also produce the same output as pip freeze by calling:

pip list

Note

The output from pip list is formatted differently, so if you have some shell script that parses the output (maybe to grab the version number) of freeze and want to change your script to call list, you'll need to change your parsing code.

Simply don't put whole commands in variables. You'll get into a lot of trouble trying to recover quoted arguments.

Also:

1. Avoid using all-capitals variable names in scripts. Easy way to shoot yourself on the foot.
2. Don't use backquotes, use $(...) instead, it nests better.

#! /bin/bash

if [ $# -ne 2 ]
then
    echo "Usage: $(basename $0) DIRECTORY BACKUP_DIRECTORY"
    exit 1
fi

directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"

tar cv "$directory" | openssl des3 -salt | split -b 1024m - "$backup_file"

As Microsoft.ReportViewer.2012.Runtime has Microsoft.ReportViewer.WebForms, Microsoft.ReportViewer.Common and Microsoft.ReportViewer.ProcessingObjectModel libraries, just run this command on PM Console:

Install-Package Microsoft.ReportViewer.2012.Runtime

Note : If you want to completely remove the old Microsoft.ReportViewer.xxx references, you can remove them from Manage NuGet Packages>Installed Packages menu and then remove the related lines from packages.config file in your project. After that it will not comeback again during building of the project.

Hope this helps...

When running in debug mode you can use the little arrow button in the debug area (Shift+Cmd+Y) in Xcode to specify a location. There are some presets or you can also add a GPX file.

You can generate GPX files here manually: http://www.bikehike.co.uk/mapview.php (from answer: https://stackoverflow.com/a/17478860/881197)

If both are not going to be modified (no adding/deleting items - modifying existing ones is fine as long as you pay heed to threading issues), you can simply pass around data.begin() + 100000 and data.begin() + 101000, and pretend that they are the begin() and end() of a smaller vector.

Or, since vector storage is guaranteed to be contiguous, you can simply pass around a 1000 item array:

T *arrayOfT = &data[0] + 100000;
size_t arrayOfTLength = 1000;

Both these techniques take constant time, but require that the length of data doesn't increase, triggering a reallocation.

An object technically is a dictionary.

var myMappings = {
    mykey1: 'myValue',
    mykey2: 'myValue'
};

var myVal = myMappings['myKey1'];

alert(myVal); // myValue

You can even loop through one.

for(var key in myMappings) {
    var myVal = myMappings[key];
    alert(myVal);
}

There is no reason whatsoever to reinvent the wheel. And of course, assignment goes like:

myMappings['mykey3'] = 'my value';

And ContainsKey:

if (myMappings.hasOwnProperty('myKey3')) {
    alert('key already exists!');
}

If you want to generate a random float in a range, try a next solution.

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


float
random_float(const float min, const float max)
{
    if (max == min) return min;
    else if (min < max) return (max - min) * ((float)rand() / RAND_MAX) + min;

    // return 0 if min > max
    return 0;
}


int
main (const int argc, const char *argv[])
{
    srand(time(NULL));

    char line[] = "-------------------------------------------";

    float data[10][2] = {
        {-10, 10},
        {-5., 5},
        {-1, 1},
        {-0.25, -0.15},
        {1.5, 1.52},
        {-1700, 8000},
        {-0.1, 0.1},
        {-1, 0},
        {-1, -2},
        {1.2, 1.1}
    };

    puts(line);
    puts("     From    |    Result    |      To");
    puts(line);


    int i;
    for (i = 0; i < 10; ++i) {
        printf("%12f | %12f | %12f\n", data[i][0], random_float(data[i][0], data[i][1]), data[i][1]);
    }

    puts(line);

    return 0;
}

I just posted a similar answer, and you probably want to have a look at:

http://www.w3.org/TR/css3-animations/#animation-events-

You can find out aspects of an animation, such as start and stop, and then, once say the 'stop' event has fired you can do whatever you want to the dom. I tried this out some time ago, and it can work, but I'd guess you're going to be restricted to webkit for the time being (but you've probably accepted that already). Btw, since I've posted the same link for 2 answers, I'd offer this general advice: check out the W3C - they pretty much write the rules and describe the standards. Also, the webkit development pages are pretty key.

public class prime{
    public static void main(String ar[])
    {
      int count;
      int no=0;
      for(int i=0;i<1000;i++){
        count=0;
        for(int j=1;j<=i;j++){

        if(i%j==0){
          count++;
         }
        }
        if(count==2){
          no++;
          if(no==Integer.parseInt(ar[0])){
            System.out.println(no+"\t"+i+"\t") ;
          }
        }
      }
    }
}

Or see cut_number from the ggplot2 package, e.g.

das$wt_2 <- as.numeric(cut_number(das$wt,3))

Note that cut(...,3) divides the range of the original data into three ranges of equal lengths; it doesn't necessarily result in the same number of observations per group if the data are unevenly distributed (you can replicate what cut_number does by using quantile appropriately, but it's a nice convenience function). On the other hand, Hmisc::cut2() using the g= argument does split by quantiles, so is more or less equivalent to ggplot2::cut_number. I might have thought that something like cut_number would have made its way into dplyr by so far, but as far as I can tell it hasn't.

I have the same problem with python 3.8.5 using venv,vscode 1.48.2 I found my solution. In (env folder)/lib/site-packages does not contains the packages. I use this setting (.vscode/settings.json)

   {
        "python.autoComplete.extraPaths": [
            "./**",
        ],
        "python.pythonPath": "env\\Scripts\\python.exe",
        "python.languageServer": "Microsoft"

Inject 'xeditable' module in your angular app(freely available):

var App = angular.module('App', ['xeditable']);

And then use its built in feature in your HTML code as follows:

<div>{{ value|number:2 }}</div>

I had the same issue on my debian server as the disk is full. No temp file could be created as no space left on device. After cleaning some files, it worked out fine.

A very short solution I use to allow a header file to contain the extern reference or actual implementation of an object. The file that actually contains the object just does #define GLOBAL_FOO_IMPLEMENTATION. Then when I add a new object to this file it shows up in that file also without me having to copy and paste the definition.

I use this pattern across multiple files. So in order to keep things as self contained as possible, I just reuse the single GLOBAL macro in each header. My header looks like this:

//file foo_globals.h
#pragma once  
#include "foo.h"  //contains definition of foo

#ifdef GLOBAL  
#undef GLOBAL  
#endif  

#ifdef GLOBAL_FOO_IMPLEMENTATION  
#define GLOBAL  
#else  
#define GLOBAL extern  
#endif  

GLOBAL Foo foo1;  
GLOBAL Foo foo2;


//file main.cpp
#define GLOBAL_FOO_IMPLEMENTATION
#include "foo_globals.h"

//file uses_extern_foo.cpp
#include "foo_globals.h

Recently I found this approach to writing logs in android, which I think is super awesome.

public static final boolean FORCED_LOGGING = true;
private static final int CALLER_STACK_INDEX = 3;

public static void showLogs(String message) {
        if (FORCED_LOGGING) {
            StackTraceElement caller = Thread.currentThread().getStackTrace()[CALLER_STACK_INDEX];

            String fullClassName = caller.getClassName();
            String className = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);
            String methodName = caller.getMethodName();
            int lineNumber = caller.getLineNumber();

            Log.i("*** " + className + "." + methodName + "():" + lineNumber + "\n" , message);
        }
    }

I'm mixing this solution with the information about howto order rows without order by (SQLAuthority.com) and the split function on MSDN (social.msdn.microsoft.com)

When you execute the prodecure

DECLARE @RC int
DECLARE @InputToSplit varchar(MAX)
DECLARE @Delimeter varchar(1)

set @InputToSplit = 'hello|beautiful|world'
set @Delimeter = '|'

EXECUTE @RC = [TransposeSplit] 
   @InputToSplit
  ,@Delimeter
GO

you obtaint the next result

  name       rowid  1      2          3
  col_value  1      hello  beautiful  world

1. Make sure you've checked out the branch you're replacing (from Zoltán's comment).

2. Assuming that master is the local branch you're replacing, and that "origin/master" is the remote branch you want to reset to:

   git reset --hard origin/master
   

This updates your local HEAD branch to be the same revision as origin/master, and --hard will sync this change into the index and workspace as well.

long negativeNumber = (long)positiveInt - (long)(int.MaxValue + 1);

Nobody said it had to be any particular negative number.

You Can Start Activity and attach RecipientsFragment on it , but you cant start Fragment

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

copy *.txt all.txt

This will concatenate all text files of the folder to one text file all.txt

If you have any other type of files, like sql files

copy *.sql all.sql

Below is an example of a method in a Java controller.

@RequestMapping(method = RequestMethod.POST)
@ResponseBody
public HttpStatus something(@RequestBody MyModel myModel) 
{
    return HttpStatus.OK;
}

By using @RequestBody annotation you will get your values mapped with the model you created in your system for handling any specific call. While by using @ResponseBody you can send anything back to the place from where the request was generated. Both things will be mapped easily without writing any custom parser etc.

You can do the following. Add your ggplot code after the first line of code and end with dev.off().

tiff("test.tiff", units="in", width=5, height=5, res=300)
# insert ggplot code
dev.off()

res=300 specifies that you need a figure with a resolution of 300 dpi. The figure file named 'test.tiff' is saved in your working directory.

Change width and height in the code above depending on the desired output.

Note that this also works for other R plots including plot, image, and pheatmap.

Other file formats

In addition to TIFF, you can easily use other image file formats including JPEG, BMP, and PNG. Some of these formats require less memory for saving.

The simplest change would be something like this:

public static void main (String[] args) throws Exception {
  testconnect obj = new testconnect();
  obj.con2 = DriverManager.getConnection(obj.getConnectionUrl2());
  obj.con2.close();
}

if you just commit your deleted file and push. It should then be removed from the remote repo.

the real solution is here, but you need to be familiar with PHP programing language. you must mix PHP and JAVASCRIPT orders in order to reach to your purpose.

pay attention to this :

<?php 
for($i=1;$i<=3;$i++){
echo "<script language='javascript' >
setTimeout(function(){alert('".$i."');},3000);  
</script>";
}
?> 

It exactly does what you want, but be careful about how to make ralation between PHP variables and JAVASCRIPT ones.

The multiple JFrame approach has been something I've implemented since I began programming Swing apps. For the most part, I did it in the beginning because I didn't know any better. However, as I matured in my experience and knowledge as a developer and as began to read and absorb the opinions of so many more experienced Java devs online, I made an attempt to shift away from the multiple JFrame approach (both in current projects and future projects) only to be met with... get this... resistance from my clients! As I began implementing modal dialogs to control "child" windows and JInternalFrames for separate components, my clients began to complain! I was quite surprised, as I was doing what I thought was best-practice! But, as they say, "A happy wife is a happy life." Same goes for your clients. Of course, I am a contractor so my end-users have direct access to me, the developer, which is obviously not a common scenario.

So, I'm going to explain the benefits of the multiple JFrame approach, as well as myth-bust some of the cons that others have presented.

1. Ultimate flexibility in layout - By allowing separate JFrames, you give your end-user the ability to spread out and control what's on his/her screen. The concept feels "open" and non-constricting. You lose this when you go towards one big JFrame and a bunch of JInternalFrames.
2. Works well for very modularized applications - In my case, most of my applications have 3 - 5 big "modules" that really have nothing to do with each other whatsoever. For instance, one module might be a sales dashboard and one might be an accounting dashboard. They don't talk to each other or anything. However, the executive might want to open both and them being separate frames on the taskbar makes his life easier.
3. Makes it easy for end-users to reference outside material - Once, I had this situation: My app had a "data viewer," from which you could click "Add New" and it would open a data entry screen. Initially, both were JFrames. However, I wanted the data entry screen to be a JDialog whose parent was the data viewer. I made the change, and immediately I received a call from an end-user who relied heavily on the fact that he could minimize or close the viewer and keep the editor open while he referenced another part of the program (or a website, I don't remember). He's not on a multi-monitor, so he needed the entry dialog to be first and something else to be second, with the data viewer completely hidden. This was impossible with a JDialog and certainly would've been impossible with a JInternalFrame as well. I begrudgingly changed it back to being separate JFrames for his sanity, but it taught me an important lesson.
4. Myth: Hard to code - This is not true in my experience. I don't see why it would be any easier to create a JInternalFrame than a JFrame. In fact, in my experience, JInternalFrames offer much less flexibility. I have developed a systematic way of handling the opening & closing of JFrames in my apps that really works well. I control the frame almost completely from within the frame's code itself; the creation of the new frame, SwingWorkers that control the retrieval of data on background threads and the GUI code on EDT, restoring/bringing to front the frame if the user tries to open it twice, etc. All you need to open my JFrames is call a public static method open() and the open method, combined with a windowClosing() event handles the rest (is the frame already open? is it not open, but loading? etc.) I made this approach a template so it's not difficult to implement for each frame.
5. Myth/Unproven: Resource Heavy - I'd like to see some facts behind this speculative statement. Although, perhaps, you could say a JFrame needs more space than a JInternalFrame, even if you open up 100 JFrames, how many more resources would you really be consuming? If your concern is memory leaks because of resources: calling dispose() frees all resources used by the frame for garbage collection (and, again I say, a JInternalFrame should invoke exactly the same concern).

I've written a lot and I feel like I could write more. Anyways, I hope I don't get down-voted simply because it's an unpopular opinion. The question is clearly a valuable one and I hope I've provided a valuable answer, even if it isn't the common opinion.

A great example of multiple frames/single document per frame (SDI) vs single frame/multiple documents per frame (MDI) is Microsoft Excel. Some of MDI benefits:

• it is possible to have a few windows in non rectangular shape - so they don't hide desktop or other window from another process (e.g. web browser)
• it is possible to open a window from another process over one Excel window while writing in second Excel window - with MDI, trying to write in one of internal windows will give focus to the entire Excel window, hence hiding window from another process
• it is possible to have different documents on different screens, which is especially useful when screens do not have the same resolution

SDI (Single-Document Interface, i.e., every window can only have a single document):

MDI (Multiple-Document Interface, i.e., every window can have multiple documents):

Check if in the csproj file there is a line/entry with the <DebugType>Full</DebugType> If it exists then try remove it and try again to debug

You can use the lock statement instead. I think this can only replace the second version. Also, remember that both synchronized and lock need to operate on an object.

I don't think you'll get a better way than your function.

It is clean, easy to follow and understand, and returns the result of the condition (no return (...) ? true : false mess).

The below solution worked for me

1. Click & open the App Store icon (1024*1024) in the preview app.
2. Export it by unticking the Alpha channel.
3. Replace the current App Store icon with the newly exported icon image.
4. Validate and upload.

Note: This will not work on Mac OS High Sierra, please try a lower version to export without alpha or use any one of the image editing applications or try out the below alternatives.

Alternative 1: (Using Sierra or High Sierra and Ionic)

1. Copy and Paste the App Store icon to the desktop.
2. Open the image. Click File Menu->Duplicate.
3. Save it by unticking the Alpha channel.
4. Replace the current App Store icon with this one.
5. Validate and upload.

Alternative 2: If duplicate does not work, try doing opening it in preview and then doing file export. I was able to unselect the alpha channel there. – by Alejandro Corredor.

Alternative 3 : Using High Sierra and Ionic, found the problem image in the following folder: [app name]/platforms/ios/[app name]/Images.xcassets/Appicon.appiconset/icon-1024.png. We have to copy it to the desktop and Save As while unchecking Alpha, then rename it to icon-1024.png, then delete the original and copy the new file back to the original folder. Export did not work though no error was displayed and all permissions were set/777. Hope this helps save someone the day I just lost. – by Ralph Hinkley

echo will normally output a newline, which is suppressed with -n. Try this:

echo -n foobar | sha256sum

class ArrayComparator implements Comparator<Comparable[]> {
    private final int columnToSort;
    private final boolean ascending;

    public ArrayComparator(int columnToSort, boolean ascending) {
        this.columnToSort = columnToSort;
        this.ascending = ascending;
    }

    public int compare(Comparable[] c1, Comparable[] c2) {
        int cmp = c1[columnToSort].compareTo(c2[columnToSort]);
        return ascending ? cmp : -cmp;
    }
}

This way you can handle any type of data in those arrays (as long as they're Comparable) and you can sort any column in ascending or descending order.

String[][] data = getData();
Arrays.sort(data, new ArrayComparator(0, true));

PS: make sure you check for ArrayIndexOutOfBounds and others.

EDIT: The above solution would only be helpful if you are able to actually store a java.util.Date in the first column or if your date format allows you to use plain String comparison for those values. Otherwise, you need to convert that String to a Date, and you can achieve that using a callback interface (as a general solution). Here's an enhanced version:

class ArrayComparator implements Comparator<Object[]> {
    private static Converter DEFAULT_CONVERTER = new Converter() {
        @Override
        public Comparable convert(Object o) {
            // simply assume the object is Comparable
            return (Comparable) o;
        }
    };
    private final int columnToSort;
    private final boolean ascending;
    private final Converter converter;


    public ArrayComparator(int columnToSort, boolean ascending) {
        this(columnToSort, ascending, DEFAULT_CONVERTER);
    }

    public ArrayComparator(int columnToSort, boolean ascending, Converter converter) {
        this.columnToSort = columnToSort;
        this.ascending = ascending;
        this.converter = converter;
    }

    public int compare(Object[] o1, Object[] o2) {
        Comparable c1 = converter.convert(o1[columnToSort]);
        Comparable c2 = converter.convert(o2[columnToSort]);
        int cmp = c1.compareTo(c2);
        return ascending ? cmp : -cmp;
    }

}

interface Converter {
    Comparable convert(Object o);
}

class DateConverter implements Converter {
    private static final DateFormat df = new SimpleDateFormat("yyyy.MM.dd hh:mm");

    @Override
    public Comparable convert(Object o) {
        try {
            return df.parse(o.toString());
        } catch (ParseException e) {
            throw new IllegalArgumentException(e);
        }
    }
}

And at this point, you can sort on your first column with:

Arrays.sort(data, new ArrayComparator(0, true, new DateConverter());

I skipped the checks for nulls and other error handling issues.

I agree this is starting to look like a framework already. :)

Last (hopefully) edit: I only now realize that your date format allows you to use plain String comparison. If that is the case, you don't need the "enhanced version".

I found it's simple to do this via the svn cat command so that you don't even have to specify a revision.

svn cat mydir/myfile > mydir/myfile

This probably won't role back the inode (metadata) data such as timestamps.

TLDR Summary

In modern MongoDB releases you can brute force this with $slice just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push to an array.

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$project": {
        "books": { "$slice": [ "$books", 2 ] },
        "count": 1
    }}
])

MongoDB 3.6 Preview

Still not resolving SERVER-9377, but in this release $lookup allows a new "non-correlated" option which takes an "pipeline" expression as an argument instead of the "localFields" and "foreignFields" options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit in order to return the "top-n" results.

db.books.aggregate([
  { "$group": {
    "_id": "$addr",
    "count": { "$sum": 1 }
  }},
  { "$sort": { "count": -1 } },
  { "$limit": 2 },
  { "$lookup": {
    "from": "books",
    "let": {
      "addr": "$_id"
    },
    "pipeline": [
      { "$match": { 
        "$expr": { "$eq": [ "$addr", "$$addr"] }
      }},
      { "$group": {
        "_id": "$book",
        "count": { "$sum": 1 }
      }},
      { "$sort": { "count": -1  } },
      { "$limit": 2 }
    ],
    "as": "books"
  }}
])

The other addition here is of course the ability to interpolate the variable through $expr using $match to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit each result separately.

This would be the next best option to running parallel queries, and actually would be better if the $match were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push" as the referenced issue asks, it actually delivers something that should work better.

Original Content

You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 }
])

Now that will give you a result like this:

{
    "result" : [
            {
                    "_id" : "address1",
                    "books" : [
                            {
                                    "book" : "book4",
                                    "count" : 1
                            },
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 3
                            }
                    ],
                    "count" : 5
            },
            {
                    "_id" : "address2",
                    "books" : [
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 2
                            }
                    ],
                    "count" : 3
            }
    ],
    "ok" : 1
}

So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.

This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$unwind": "$books" },
    { "$sort": { "count": 1, "books.count": -1 } },
    { "$group": {
        "_id": "$_id",
        "books": { "$push": "$books" },
        "count": { "$first": "$count" }
    }},
    { "$project": {
        "_id": {
            "_id": "$_id",
            "books": "$books",
            "count": "$count"
        },
        "newBooks": "$books"
    }},
    { "$unwind": "$newBooks" },
    { "$group": {
      "_id": "$_id",
      "num1": { "$first": "$newBooks" }
    }},
    { "$project": {
        "_id": "$_id",
        "newBooks": "$_id.books",
        "num1": 1
    }},
    { "$unwind": "$newBooks" },
    { "$project": {
        "_id": "$_id",
        "num1": 1,
        "newBooks": 1,
        "seen": { "$eq": [
            "$num1",
            "$newBooks"
        ]}
    }},
    { "$match": { "seen": false } },
    { "$group":{
        "_id": "$_id._id",
        "num1": { "$first": "$num1" },
        "num2": { "$first": "$newBooks" },
        "count": { "$first": "$_id.count" }
    }},
    { "$project": {
        "num1": 1,
        "num2": 1,
        "count": 1,
        "type": { "$cond": [ 1, [true,false],0 ] }
    }},
    { "$unwind": "$type" },
    { "$project": {
        "books": { "$cond": [
            "$type",
            "$num1",
            "$num2"
        ]},
        "count": 1
    }},
    { "$group": {
        "_id": "$_id",
        "count": { "$first": "$count" },
        "books": { "$push": "$books" }
    }},
    { "$sort": { "count": -1 } }
])

So that will actually give you the top 2 "books" from the top two "address" entries.

But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.

Demonstration Code

The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

Use MySQL's FIELD() function:

SELECT name, description, ...
FROM ...
WHERE id IN([ids, any order])
ORDER BY FIELD(id, [ids in order])

FIELD() will return the index of the first parameter that is equal to the first parameter (other than the first parameter itself).

FIELD('a', 'a', 'b', 'c')

will return 1

FIELD('a', 'c', 'b', 'a')

will return 3

This will do exactly what you want if you paste the ids into the IN() clause and the FIELD() function in the same order.

Use pip install mysql-connector-python

Then connect like this:

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",               #hostname
  user="Harish",                   # the user who has privilege to the db
  passwd="Harish96",               #password for user
  database="Factdb",               #database name
    auth_plugin = 'mysql_native_password',

)

select substring(ColumnName, patindex('%[^0]%',ColumnName), 10)

You can use the built in cache attribute to prevent caching.

For .net Framework: [OutputCache(NoStore = true, Duration = 0)]

For .net Core: [ResponseCache(NoStore = true, Duration = 0)]

Be aware that it is impossible to force the browser to disable caching. The best you can do is provide suggestions that most browsers will honor, usually in the form of headers or meta tags. This decorator attribute will disable server caching and also add this header: Cache-Control: public, no-store, max-age=0. It does not add meta tags. If desired, those can be added manually in the view.

Additionally, JQuery and other client frameworks will attempt to trick the browser into not using it's cached version of a resource by adding stuff to the url, like a timestamp or GUID. This is effective in making the browser ask for the resource again but doesn't really prevent caching.

On a final note. You should be aware that resources can also be cached in between the server and client. ISP's, proxies, and other network devices also cache resources and they often use internal rules without looking at the actual resource. There isn't much you can do about these. The good news is that they typically cache for shorter time frames, like seconds or minutes.

def split(arr, size):
     arrs = []
     while len(arr) > size:
         pice = arr[:size]
         arrs.append(pice)
         arr   = arr[size:]
     arrs.append(arr)
     return arrs

Test:

x=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
print(split(x, 5))

result:

[[1, 2, 3, 4, 5], [6, 7, 8, 9, 10], [11, 12, 13]]

InternetAddress.Parse is going to be your friend! See the worked example below:

String to = "[email protected], [email protected], [email protected]";
String toCommaAndSpaces = "[email protected] [email protected], [email protected]";

1. Parse a comma-separated list of email addresses. Be strict. Require comma separated list.

2. If strict is true, many (but not all) of the RFC822 syntax rules for emails are enforced.

   msg.setRecipients(Message.RecipientType.CC,
   InternetAddress.parse(to, true));
   

3. Parse comma/space-separated list. Cut some slack. We allow spaces seperated list as well, plus invalid email formats.

   msg.setRecipients(Message.RecipientType.BCC,
   InternetAddress.parse(toCommaAndSpaces, false));
   

quite possibly the simplest method ...

<?php
$change = array('key1' => $var1, 'key2' => $var2, 'key3' => $var3);
echo json_encode(change);
?>

Then the jquery script ...

<script>
$.get("location.php", function(data){
var duce = jQuery.parseJSON(data);
var art1 = duce.key1;
var art2 = duce.key2;
var art3 = duce.key3;
});
</script>

If the select is show results one have to use this:

$('#yourSelect2ControlId').select2("close").parent().hide();

it closes the search results box and then set control unvisible

Just in case if you want to do this using an npm package semver link

let fs = require('fs');
let semver = require('semver');

if (fs.existsSync('./package.json')) {
    var package = require('./package.json');
    let currentVersion = package.version;
    let type = process.argv[2];
    if (!['major', 'minor', 'patch'].includes(type)) {
        type = 'patch';
    }

    let newVersion = semver.inc(package.version, type);
    package.version = newVersion;
    fs.writeFileSync('./package.json', JSON.stringify(package, null, 2));

    console.log('Version updated', currentVersion, '=>', newVersion);
}

package.json should look like,

{
  "name": "versioning",
  "version": "0.0.0",
  "description": "Update version in package.json using npm script",
  "main": "version.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "version": "node version.js"
  },
  "author": "Bhadresh Arya",
  "license": "ISC",
  "dependencies": {
    "semver": "^7.3.2"
  }
}

just pass major, minor, patch argument with npm run version. Default will be patch.

example: npm run version or npm run verison patch or npm run verison minor or npm run version major

Git Repo

It seems like most answers here are focused on the master branch; however, there are times when I'm working on the same feature branch in two different places and I want a rebase in one to be reflected in the other without a lot of jumping through hoops.

Based on a combination of RNA's answer and torek's answer to a similar question, I've come up with this which works splendidly:

git fetch
git reset --hard @{u}

Run this from a branch and it'll only reset your local branch to the upstream version.

This can be nicely put into a git alias (git forcepull) as well:

git config alias.forcepull "!git fetch ; git reset --hard @{u}"

Or, in your .gitconfig file:

[alias]
  forcepull = "!git fetch ; git reset --hard @{u}"

Enjoy!

public void printGrid()
{
   for(int i = 0; i < 20; i++)
   {
      for(int j = 0; j < 20; j++)
      {
         System.out.printf("%5d ", a[i][j]);
      }
      System.out.println();
   }
}

And to replace

public void replaceGrid()
{
   for (int i = 0; i < 20; i++)
   {
      for (int j = 0; j < 20; j++)
      {
         if (a[i][j] == 1)
            a[i][j] = x;
      }
   }
}

And you can do this all in one go:

public void printAndReplaceGrid()
{
   for(int i = 0; i < 20; i++)
   {
      for(int j = 0; j < 20; j++)
      {
         if (a[i][j] == 1)
            a[i][j] = x;
         System.out.printf("%5d ", a[i][j]);
      }
      System.out.println();
   }
}

I was also trying to get Debug or Trace or Console or TestContext to work in unit testing.

None of these methods would appear to work or show output in the output window:

    Trace.WriteLine("test trace");
    Debug.WriteLine("test debug");
    TestContext.WriteLine("test context");
    Console.WriteLine("test console");

Visual Studio 2012 and greater

(from comments) In Visual Studio 2012, there is no icon. Instead, there is a link in the test results called Output. If you click on the link, you see all of the WriteLine.

Prior to Visual Studio 2012

I then noticed in my Test Results window, after running the test, next to the little success green circle, there is another icon. I doubled clicked it. It was my test results, and it included all of the types of writelines above.

Try this:

Dim text As String = ""
Dim files() As String = IO.Directory.GetFiles(sFolder)

For Each sFile As String In files
    text &= IO.File.ReadAllText(sFile)
Next

for ($s=65; $s<=90; $s++) {
    //echo chr($s);
    $objPHPExcel->getActiveSheet()->getColumnDimension(chr($s))->setAutoSize(true);
}

You're trying to call the isEmpty() method on a null reference (as List test = null; ). This will surely throw a NullPointerException. You should do if(test!=null) instead (Checking for null first).

The method isEmpty() returns true, if an ArrayList object contains no elements; false otherwise (for that the List must first be instantiated that is in your case is null).

Edit:

You may want to see this question.

You can specify a callback function:

$(selector).fadeOut('slow', function() {
    // will be called when the element finishes fading out
    // if selector matches multiple elements it will be called once for each
});

Documentation here.

The first 2 examples act very differently if you are REPLACING them by something. If you match on this:

str = str.replace(/^(7|8|9)/ig,''); 

you would replace 7 or 8 or 9 by the empty string.

If you match on this

str = str.replace(/^[7|8|9]/ig,''); 

you will replace 7 or 8 or 9 OR THE VERTICAL BAR!!!! by the empty string.

I just found this out the hard way.

$('#navigation ul li').css({'display' : 'inline-block'});

It seems a typo there ...syntax mistake :))

EDIT: I've added one more option for bootstrap sidebars.

There are actually three manners in which you can make a bootstrap 3 sidebar. I tried to keep the code as simple as possible.

Fixed sidebar

Here you can see a demo of a simple fixed sidebar I've developed with the same height as the page

Sidebar in a column

I've also developed a rather simple column sidebar that works in a two or three column page inside a container. It takes the length of the longest column. Here you can see a demo

Dashboard

If you google bootstrap dashboard, you can find multiple suitable dashboard, such as this one. However, most of them require a lot of coding. I've developed a dashboard that works without additional javascript (next to the bootstrap javascript). Here is a demo

For all three examples you off course have to include the jquery, bootstrap css, js and theme.css files.

Slidebar

If you want the sidebar to hide on pressing a button this is also possible with only a little javascript.Here is a demo

There is no need to use Babel at this moment (JS has become very powerful) when you can simply use the default JavaScript module exports. Check full tutorial

Message.js

module.exports = 'Hello world';

app.js

var msg = require('./Messages.js');

console.log(msg); // Hello World

I was trying do the same of making a particular file my default page, instead of directory structure. So in IIS server I had to go to Default Document, add the page that I want to make as default and at the same time, go to the Web.config file and update the defaultDocument header with "enabled=true". This worked for me. Hopefully it helps.

We have used the combination of:

1. Cobian Backup for scheduling/maintenance

2. ExpressMaint for backup

Both of these are free. The process is to script ExpressMaint to take a backup as a Cobian "before Backup" event. I usually let this overwrite the previous backup file. Cobian then takes a zip/7zip out of this and archives these to the backup folder. In Cobian you can specify the number of full copies to keep, make multiple backup cycles etc.

ExpressMaint command syntax example:

expressmaint -S HOST\SQLEXPRESS -D ALL_USER -T DB -R logpath -RU WEEKS -RV 1 -B backuppath -BU HOURS -BV 3 

I am using Tensorflow version 2.3.1 and none of the solutions above have been fully effective.
Until, I find this package.

Install like this:

with Anaconda,

python -m pip install silence-tensorflow

with IDEs,

pip install silence-tensorflow

And add to the first line of code:

from silence_tensorflow import silence_tensorflow
silence_tensorflow()

That's It!

you can easily find the current CodeIgniter version by

echo CI_VERSION 


or you can navigate to System->core->codeigniter.php file and you can see the constant

/**
 * CodeIgniter Version
 *
 * @var string
 *
 */
    const CI_VERSION = '3.1.6';

Here are few steps that must be followed carefully

1. First of all make sure that the WAMP server is running if it is not running, start the server.
2. Enter the URL http://localhost/phpmyadmin/setup in address bar of your browser.

3. Create a folder named config inside C:\wamp\apps\phpmyadmin, the folder inside apps may have different name like phpmyadmin3.2.0.1

4. Return to your browser in phpmyadmin setup tab, and click New server.

5. Change the authentication type to ‘cookie’ and leave the username and password field empty but if you change the authentication type to ‘config’ enter the password for username root.

6. Click save

7. Again click save in configuration file option.
8. Now navigate to the config folder. Inside the folder there will be a file named config.inc.php. Copy the file and paste it out of the folder (if the file with same name is already there then override it) and finally delete the folder.
9. Now you are done. Try to connect the mysql server again and this time you won’t get any error. --credits Bibek Subedi

The following helped me in Win10.

• Add %M3_HOME%\bin; as value for Path variable under User Variables.
• Add full path to maven binary folder as Variable Value for M3_HOME variable under System Variables.
• Add %M3_HOME%\bin; as value for Path variable under System Variables.
• Click OK wherever applicable.
• Close the existing command prompt.
• Open new command prompt and navigate to Maven binary folder.
• Type mvn -version

It will work.

I just wanted to hop in here and correct (suggest alternative) to the previous answer....

You can actually use compact in the same way, however a lot neater for example...

return View::make('gameworlds.mygame', compact(array('fixtures', 'teams', 'selections')));

Or if you are using PHP > 5.4

return View::make('gameworlds.mygame', compact(['fixtures', 'teams', 'selections']));

This is far neater, and still allows for readability when reviewing what the application does ;)

Up to date and complete answer with Jackson 2

Using Annotation

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

@JsonIgnoreProperties(ignoreUnknown = true)
public class MyMappingClass {

}

See JsonIgnoreProperties on Jackson online documentation.

Using Configuration

Less intrusive than annotation.

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.ObjectReader;

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

ObjectReader objectReader = objectMapper.reader(MyMappingClass.class);
MyMappingClass myMappingClass = objectReader.readValue(json);

See FAIL_ON_UNKNOWN_PROPERTIES on Jackson online documentation.

If you are running out of memory and getting an OutOfMemoryException you can try increasing the amount of heap space available to java by starting you program with java -Xms128m -Xmx512m instead of just java. This will give you an initial heap size of 128Mb and a maximum of 512Mb, which is far more than the standard 32Mb/128Mb.

SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss a");

I could NOT solve this. I had CORS enabled and working as long as the POST returned void (ASP.NET 4.0 - WEBAPI 1). When I tried to return a HttpResponseMessage, I started getting the HTTP 405 response.

Based on Llad's response above, I took a look at my own references.

I had the attribute [System.Web.Mvc.HttpPost] listed above my POST method.

I changed this to use:

[System.Web.Http.HttpPostAttribute]
[HttpOptions]
public HttpResponseMessage Post(object json)        
{
    ...
    return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
}

This fixed my woes. I hope this helps someone else.

For the sake of completeness, I had the following in my web.config:

<httpProtocol>
    <customHeaders>
        <clear />
        <add name="Access-Control-Expose-Headers " value="WWW-Authenticate"/>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, PATCH, DELETE" />
        <add name="Access-Control-Allow-Headers" value="accept, authorization, Content-Type" />
        <remove name="X-Powered-By" />
    </customHeaders>
</httpProtocol>

In my case, I copied my class from somewhere else and didn't notice right away that it was an abstract class. You can't inflate abstract classes.

I Think this Works:

 testGV.HeaderRow.Cells[0].Text="Date"

If you want to import a specific function or class from a module, you can do this:

import importlib
import sys
importlib.reload(sys.modules['my_module'])
from my_module import my_function

I use Shift + F12 to show the Console again (or Window > Restore Default Layout).

To enable that, I have previously saved the layout WITH the console open as default (Window > Store Current Layout as Default).

Like in other answers, start your span attributes with this:

display:inline-block;  

Now you can use padding more than width:

padding-left:6%;
padding-right:6%;

When you use padding, your color expands to both side (right and left), not just right (like in widht).

REST is a software design pattern typically used for web applications. In layman's terms this means that it is a commonly used idea used in many different projects. It stands for REpresentational State Transfer. The basic idea of REST is treating objects on the server-side (as in rows in a database table) as resources than can be created or destroyed.

The most basic way of thinking about REST is as a way of formatting the URLs of your web applications. For example, if your resource was called "posts", then:

/posts Would be how a user would access ALL the posts, for displaying.

/posts/:id Would be how a user would access and view an individual post, retrieved based on their unique id.

/posts/new Would be how you would display a form for creating a new post.

Sending a POST request to /users would be how you would actually create a new post on the database level.

Sending a PUT request to /users/:id would be how you would update the attributes of a given post, again identified by a unique id.

Sending a DELETE request to /users/:id would be how you would delete a given post, again identified by a unique id.

As I understand it, the REST pattern was mainly popularized (for web apps) by the Ruby on Rails framework, which puts a big emphasis on RESTful routes. I could be wrong about that though.

I may not be the most qualified to talk about it, but this is how I've learned it (specifically for Rails development).

When someone refers to a "REST api," generally what they mean is an api that uses RESTful urls for retrieving data.

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

declare @PersonID int
set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID    
    )    
    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END
ELSE
    IF NOT EXISTS
        (
        SELECT 1
        FROM Timesheet_Hours
        WHERE Staff_Id = @PersonID
        )
        BEGIN
            RAISERROR('Default list has not been loaded!', 16, 1)
            ROLLBACK TRAN
        END
    ELSE
        print 'No problems here'

drop table Timesheet_Hours

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

Here is a example of embedding without an iFrame:

<div style="width: 560px; height: 315px; float: none; clear: both; margin: 2px auto;">
  <embed
    src="https://www.youtube.com/embed/J---aiyznGQ?autohide=1&autoplay=1"
    wmode="transparent"
    type="video/mp4"
    width="100%" height="100%"
    allow="autoplay; encrypted-media; picture-in-picture"
    allowfullscreen
    title="Keyboard Cat"
  >
</div>

compare to regular iframe "embed" code from YouTube:

<iframe
  width="560"
  height="315"
  src="https://www.youtube.com/embed/J---aiyznGQ?autoplay=1"
  frameborder="0"
  allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"
  allowfullscreen>
</iframe>

and as far as HTML5 goes, use <object> tag like so (corrected):

<object
  style="width: 820px; height: 461.25px; float: none; clear: both; margin: 2px auto;"
  data="http://www.youtube.com/embed/J---aiyznGQ?autoplay=1">
</object>

Covert .ppk to id_rsa using tool PuttyGen, (http://mydailyfindingsit.blogspot.in/2015/08/create-keys-for-your-linux-machine.html) and

scp -C -i ./id_rsa -r /var/www/* [email protected]:/var/www

it should work !

Technically slice is the fastest way. However, it is even faster if you add the 0 begin index.

myArray.slice(0);

is faster than

myArray.slice();

http://jsperf.com/cloning-arrays/3

Modify your HTML like this:

<table border="0" cellpadding="0" cellspacing="0">
    <thead>
        <tr><td>1</td><td>2</td><td>3</td></tr>
     </thead>
    <tbody>
        <tr><td>a</td><td>b></td><td>c</td></tr>
        <tr class='odd'><td>x</td><td>y</td><td>z</td></tr>
    </tbody>
</table>

(I added border="0" cellpadding="0" cellspacing="0")

In CSS, you could do the following:

table {
    border-collapse: collapse;
}

Unless you're in a specific speed optimization process, I would say use whichever method produces the easiest to read and maintain code.

If an iterator is already setup, like with one of the collection classes, then the foreach is a good easy option. And if it's an integer range you're iterating, then for is probably cleaner.

You can use

LEFT(column, length)

or

SUBSTRING(column, start index, length)

#include <stdio.h>
main()
{
int c,sp,tb,nl;
sp = 0;
tb = 0;
nl = 0;
while((c = getchar()) != EOF)
{
   switch( c )
{
   case ' ':
        ++sp;
     printf("space:%d\n", sp);
     break;
   case  '\t':
        ++tb;
     printf("tab:%d\n", tb);
     break;
   case '\n':
        ++nl;
     printf("new line:%d\n", nl);
     break;
  }
 }
}

To check if an element contains a class, you use the contains() method of the classList property of the element:*

element.classList.contains(className);

*Suppose you have the following element:

<div class="secondary info">Item</div>*

To check if the element contains the secondary class, you use the following code:

 const div = document.querySelector('div');
 div.classList.contains('secondary'); // true

The following returns false because the element doesn’t have the class error:

 const div = document.querySelector('div');
 div.classList.contains('error'); // false

The basic difference between UNION and UNION ALL is union operation eliminates the duplicated rows from the result set but union all returns all rows after joining.

from http://zengin.wordpress.com/2007/07/31/union-vs-union-all/

You could also just call to_a after each_byte or even better String#bytes

=> 'hello world'.each_byte.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

=> 'hello world'.bytes
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

1. If you have released to Apple TestFlight for testing

   You have to click the link each time and select No, only after that, your tester can see the build. This is quite annoying if you want to get your build delivered as soon as possible.

   

2. Do this for the next build, (If do this before the build then this error will not occur)

The solution is add the following setting to your iOS Info.plist:

    <key>ITSAppUsesNonExemptEncryption</key>
    <false/>

Can not add "Missing Compliance", see this Missing Compliance

Eg:

if 'newsletter_sub' in request.POST:
    # do subscribe
elif 'newsletter_unsub' in request.POST:
    # do unsubscribe

There are two things you can do:

1. Add the @Deprecated annotation to the method, and
2. Add a @deprecated tag to the javadoc of the method

You should do both!

Quoting the java documentation on this subject:

Starting with J2SE 5.0, you deprecate a class, method, or field by using the @Deprecated annotation. Additionally, you can use the @deprecated Javadoc tag tell developers what to use instead.

Using the annotation causes the Java compiler to generate warnings when the deprecated class, method, or field is used. The compiler suppresses deprecation warnings if a deprecated compilation unit uses a deprecated class, method, or field. This enables you to build legacy APIs without generating warnings.

You are strongly recommended to use the Javadoc @deprecated tag with appropriate comments explaining how to use the new API. This ensures developers will have a workable migration path from the old API to the new API

Example

So, if we had a child element with an id of "child-element" and we wanted to get it's left/top position relative to a parent element, say a div that had a class of "item-parent", we'd use this code.

var position = $("#child-element").offsetRelative("div.item-parent");
alert('left: '+position.left+', top: '+position.top);

Plugin Finally, for the actual plugin (with a few notes expalaining what's going on):

// offsetRelative (or, if you prefer, positionRelative)
(function($){
    $.fn.offsetRelative = function(top){
        var $this = $(this);
        var $parent = $this.offsetParent();
        var offset = $this.position();
        if(!top) return offset; // Didn't pass a 'top' element 
        else if($parent.get(0).tagName == "BODY") return offset; // Reached top of document
        else if($(top,$parent).length) return offset; // Parent element contains the 'top' element we want the offset to be relative to 
        else if($parent[0] == $(top)[0]) return offset; // Reached the 'top' element we want the offset to be relative to 
        else { // Get parent's relative offset
            var parent_offset = $parent.offsetRelative(top);
            offset.top += parent_offset.top;
            offset.left += parent_offset.left;
            return offset;
        }
    };
    $.fn.positionRelative = function(top){
        return $(this).offsetRelative(top);
    };
}(jQuery));

Note : You can Use this on mouseClick or mouseover Event

$(this).offsetRelative("div.item-parent");

You can use $.isEmptyObject(json)

This could help;

Path.GetDirectoryName(Application.ExecutablePath);

also here is the reference

Make this in your test.ps1, at the first line

param(
[string]$a
)

Write-Host $a

Then you can call it with

./Test.ps1 "Here is your text"

$DISPLAY is the standard way. That's how users communicate with programs about which X server to use, if any.

If you are using xml configuration, you'll need something like the following in an applicationContext.xml file:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" lazy-init="default" autowire="default" dependency-check="default">
<property name="dataSource">
  <ref bean="dataSource" />
</property>
<property name="annotatedClasses">
  <list>
    <value>org.browsexml.timesheetjob.model.PositionCode</value>
  </list>

The command :hide will hide the currently focused window. I think this is the functionality you are looking for.

In order to navigate between windows type Ctrl+w followed by a navigation key (h,j,k,l, or arrow keys)

For more information run :help window and :help hide in vim.

As the other answers state there is no way getting query string parameters using servlet api.

So, I think the best way to get query parameters is parsing the query string yourself. ( It is more complicated iterating over parameters and checking if query string contains the parameter)

I wrote below code to get query string parameters. Using apache StringUtils and ArrayUtils which supports CSV separated query param values as well.

Example: username=james&username=smith&password=pwd1,pwd2 will return

password : [pwd1, pwd2] (length = 2)

username : [james, smith] (length = 2)

public static Map<String, String[]> getQueryParameters(HttpServletRequest request) throws UnsupportedEncodingException {
    Map<String, String[]> queryParameters = new HashMap<>();

I have 2 methods for you.

Method 1. demo on jsFiddle

This method resize image only visual not it actual dimensions in DOM, and visual state after resize centered in middle of original size.

html:

<img class="fake" src="example.png" />

css:

img {
  -webkit-transform: scale(0.5); /* Saf3.1+, Chrome */
     -moz-transform: scale(0.5); /* FF3.5+ */
      -ms-transform: scale(0.5); /* IE9 */
       -o-transform: scale(0.5); /* Opera 10.5+ */
          transform: scale(0.5);
             /* IE6–IE9 */
             filter: progid:DXImageTransform.Microsoft.Matrix(M11=0.9999619230641713, M12=-0.008726535498373935, M21=0.008726535498373935, M22=0.9999619230641713,SizingMethod='auto expand');
}?

Browser support note: browsers statistics showed inline in css.

Method 2. demo on jsFiddle

html:

<div id="wrap">
    <img class="fake" src="example.png" />
    <div id="img_wrap">
        <img class="normal" src="example.png" />
    </div>
</div>?

css:

#wrap {
    overflow: hidden;
    position: relative;
    float: left;
}

#wrap img.fake {
    float: left;
    visibility: hidden;
    width: auto;
}

#img_wrap {
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
}

#img_wrap img.normal {
    width: 50%;
}?

Note: img.normal and img.fake is the same image.
Browser support note: This method will work in all browsers, because all browsers support css properties used in method.

The method works in this way:

1. #wrap and #wrap img.fake have flow
2. #wrap has overflow: hidden so that its dimensions are identical to inner image (img.fake)
3. img.fake is the only element inside #wrap without absolute positioning so that it doesn't break the second step
4. #img_wrap has absolute positioning inside #wrap and extends in size to the entire element (#wrap)
5. The result of the fourth step is that #img_wrap has the same dimensions as the image.
6. By setting width: 50% on img.normal, its size is 50% of #img_wrap, and therefore 50% of the original image size.

sometimes while not found sp_send_dbmail directly. You may use 'msdb.dbo.sp_send_dbmail' to try (Work fine on Windows Server 2008 R2 and is tested)

I know that is late to respond, but there are a basic way to do it, with no libraries. If your number is less than 100, then:

(number/100).toFixed(2).toString().slice(2);

Watch out for zero-byte .plugin files in the {WORKSPACE-DIR}/.metadata/.plugins folder. I just deleted one in there and it fixed my freezing issues.

You can use:

$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);

Jsfiddle

Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.

Maybe smooth.spline is an option, You can set a smoothing parameter (typically between 0 and 1) here

smoothingSpline = smooth.spline(x, y, spar=0.35)
plot(x,y)
lines(smoothingSpline)

you can also use predict on smooth.spline objects. The function comes with base R, see ?smooth.spline for details.

When you use

cmd.Parameters.Add("@RETURN_VALUE", SqlDbType.Int).Direction = ParameterDirection.ReturnValue;

you must then ensure your stored procedure has

return @RETURN_VALUE;

at the end of the stored procedure.

Use this code for IE9 and above:

window.frames["printf"].focus();
window.frames["printf"].print();

For IE8:

window.frames[0].focus();
window.frames[0].print();
