It would be Better if you can use html5 video player or any other player (but not jwplayer) which can play youtube source video.

Below is an example source url of a video: https://redirector.googlevideo.com/videoplayback?requiressl=yes&id=a1385c04a9ecb45b&itag=22&source=picasa&cmo=secure_transport%3Dyes&ip=0.0.0.0&ipbits=0&expire=1440066674&sparams=requiressl%2Cid%2Citag%2Csource%2Cip%2Cipbits%2Cexpire&signature=86FE7D007A1DC990288890ED4EC7AA2D31A2ABF2.A0A23B872725261C457B67FD4757F3EB856AEE0E&key=lh1

Open this using simple html5 video player (Replace XXXXXX with source url or any downloadable url) :

    <video width="640" height="480" autoplay controls>
  <source src="XXXXXX" type="video/mp4">
 </video>

You can also use many other video players also.

 <div class="navbar navbar-default navbar-fixed-top" role="navigation">
        <div class="container">
            <div class="navbar-header" >
               <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">

                   <span class="icon-bar"></span>
                   <span class="icon-bar"></span>
                   <span class="icon-bar"></span>

//Don't forgot to add bootstrap in head of your code.

although I suggest to use youtube api or call new intent and make the system handle it (i.e. youtube app), here some code that can help you, it has a call to an hidden method because you can't pause and resume webview

    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        String media_url = VIDEO_URL;

        mWebView = (WebView) findViewById(R.id.webview);
        mWebView.setWebChromeClient(new WebChromeClient());

Playlist hack didn't work for me either. Working workaround for September 2018 (bonus: set width and height by CSS for #yt-wrap instead of hard-coding it in JS):

<div id="yt-wrap">
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <div id="ytplayer"></div>
</div>

<script>
  // 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      width: '100%',
      height: '100%',
      videoId: 'VIDEO_ID',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.playVideo();
    player.mute(); // comment out if you don't want the auto played video muted
  }

  // 5. The API calls this function when the player's state changes.
  //    The function indicates that when playing a video (state=1),
  //    the player should play for six seconds and then stop.
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.ENDED) {
      player.seekTo(0);
      player.playVideo();
    }

You can customize material styles by setting different color properties. For example custom application theme

<style name="CustomAppTheme" parent="Theme.AppCompat">
    <item name="android:textColorPrimaryDisableOnly">#00838f</item>
    <item name="colorAccent">#e91e63</item>
</style>

Custom switch theme

<style name="MySwitch" parent="@style/Widget.AppCompat.CompoundButton.Switch">
    <item name="android:textColorPrimaryDisableOnly">#b71c1c</item>
    <item name="android:colorControlActivated">#1b5e20</item>
    <item name="android:colorForeground">#f57f17</item>
    <item name="android:textAppearance">@style/TextAppearance.AppCompat</item>
</style>

You can customize switch track and switch thumb like below image by defining xml drawables. For more information http://www.zoftino.com/android-switch-button-and-custom-switch-examples

you need to put it after wp_head(); Because that loads your jQuery and you need to load jQuery first and then your js

I discovered that this can all be done in one file fairly easily. Put something like the following code in a file named custom_button.xml and then set background="@drawable/custom_button" in your button view:

Taken from the css3mediaqueries.js project page.

Note: Doesn't work on @import'ed stylesheets (which you shouldn't use anyway for performance reasons). Also won't listen to the media attribute of the <link> and <style> elements.

Another alternative to do the same thing is to filter on type=checkbox attribute:

$('input[type="checkbox"]').removeAttr('checked');

or

$('input[type="checkbox"]').prop('checked' , false);

Remeber that The difference between attributes and properties can be important in specific situations. Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

I think these both blog post should help you solving your problem.

http://blog.the-dargans.co.uk/2007/04/programmatically-adding-items-to.html http://asadewa.wordpress.com/2007/11/19/adding-a-custom-content-type-specific-item-on-a-sharepoint-list/

Short walk through:

1. Get a instance of the list you want to add the item to.

2. Add a new item to the list:

   SPListItem newItem = list.AddItem();
   

3. To bind you new item to a content type you have to set the content type id for the new item:

   newItem["ContentTypeId"] = <Id of the content type>;
   

4. Set the fields specified within your content type.

5. Commit your changes:

   newItem.Update();
   

You can use z for size_t and t for ptrdiff_t like in

printf("%zu %td", size, ptrdiff);

But my manpage says some older library used a different character than z and discourages use of it. Nevertheless, it's standardized (by the C99 standard). For those intmax_t and int8_t of stdint.h and so on, there are macros you can use, like another answer said:

printf("value: %" PRId32, some_int32_t);
printf("value: %" PRIu16, some_uint16_t);

They are listed in the manpage of inttypes.h.

Personally, I would just cast the values to unsigned long or long like another answer recommends. If you use C99, then you can (and should, of course) cast to unsigned long long or long long and use the %llu or %lld formats respectively.

Object Oriented Programming offers:

1. Encapsulation, to
   • control mutation of internal state
   • limit coupling to internal representation
2. Subtyping, allowing:
   • substitution of compatible types (polymorphism)
   • a crude means of sharing implementation between classes (implementation inheritance)

Functional Programming, in Haskell or even in Scala, can allow substitution through more general mechanism of type classes. Mutable internal state is either discouraged or forbidden. Encapsulation of internal representation can also be achieved. See Haskell vs OOP for a good comparison.

Norman's assertion that "Adding a new kind of thing to a functional program may require editing many function definitions to add a new case." depends on how well the functional code has employed type classes. If Pattern Matching on a particular Abstract Data Type is spread throughout a codebase, you will indeed suffer from this problem, but it is perhaps a poor design to start with.

EDITED Removed reference to implicit conversions when discussing type classes. In Scala, type classes are encoded with implicit parameters, not conversions, although implicit conversions are another means to acheiving substitution of compatible types.

Scenario: Windows 8.1, VS2013 Ultimate, SQL Express Installed and running, SQL Server Browser Disabled. This worked for me:

1. First I enabled SQL Server Browser under services.
2. In Visual Studio: Open the Package Manager Console then type: Enable-Migrations; Then Type Enable-Migrations -ContextTypeName YourContextDbName that created the Migrations folder in VS.
3. Inside the Migrations folder you will find the "Configuration.cs" file, turn on automatic migrations by: AutomaticMigrationsEnabled = true;
4. Run your application again, the environment creates a DefaultConnection and you will see the new tables from your context. This new connection points to the localdb. The created connection string shows: Data Source=(LocalDb)\v11.0 ... (more parameters and path to the created mdf file)

You can now create a new connection with Server name: (LocalDb)\v11.0 (hit refresh) Connect to a database: Select your new database under the dropdown.

I hope it helps.

There is now a php artisan view:clear command for this task since Laravel 5.1

Riya,

Making the assumption that you want to split on the full stop (.), then here's an approach that would capture all occurences:

// add @ to the string to allow split over multiple lines 
// (display purposes to save scroll bar appearing on SO question :))
string strBig = @"Retrieves a substring from this instance. 
            The substring starts at a specified character position. great";

// split the string on the fullstop, if it has a length>0
// then, trim that string to remove any undesired spaces
IEnumerable<string> subwords = strBig.Split('.')
    .Where(x => x.Length > 0).Select(x => x.Trim());

// iterate around the new 'collection' to sanity check it
foreach (var subword in subwords)
{
    Console.WriteLine(subword);
}

enjoy...

Download the latest version of the Chrome driver and use this code:

System.setProperty("webdriver.chrome.driver", "path of chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
Thread.sleep(10000);
driver.get("http://stackoverflow.com");
    

SWIFT 4:

extension Date
{
    func hour() -> Int
    {
    //Get Hour
    let calendar = Calendar.current
    let components = calendar.component(.hour, from: self)
    let hour = components

    //Return Hour
    return hour
    }


    func minute() -> Int
    {
    //Get Minute
    let calendar = Calendar.current
    let components = calendar.component(.minute, from: self)
    let minute = components

    //Return Minute
    return minute
        }
}

To install it, just run the command

npm install jquery

or

yarn add jquery

then you can import it in your file like

import $ from 'jquery';

You can simply add another join like this:

SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data 
    INNER JOIN dashboard_messages 
        ON dashboard_message_id = dashboard_messages.id
    INNER JOIN images
        ON dashboard_messages.image_id = images.image_id 

However be aware that, because it is an INNER JOIN, if you have a message without an image, the entire row will be skipped. If this is a possibility, you may want to do a LEFT OUTER JOIN which will return all your dashboard messages and an image_filename only if one exists (otherwise you'll get a null)

SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data 
    INNER JOIN dashboard_messages 
        ON dashboard_message_id = dashboard_messages.id
    LEFT OUTER JOIN images
        ON dashboard_messages.image_id = images.image_id

</video>
</div>

<div>Current Time : <span  id="currentTime">0</span></div>
<div>Total time : <span id="totalTime">0</span></div>

JS

$(function(){
$('#currentTime').html($('#video_container').find('video').get(0).load());
$('#currentTime').html($('#video_container').find('video').get(0).play());
})
setInterval(function(){
$('#currentTime').html($('#video_container').find('video').get(0).currentTime);
$('#totalTime').html($('#video_container').find('video').get(0).duration);    
},500)

I also face a situation when I needed to return a top result but also wanted to get the total rows that where matching the query. i finaly get to this solution:

   public string Format(SelectQuery selectQuery)
    {
      string result;

      if (string.IsNullOrWhiteSpace(selectQuery.WherePart))
      {
        result = string.Format(
@"
declare @maxResult  int;
set @maxResult = {0};

WITH Total AS
(
SELECT count(*) as [Count] FROM {2}
)
SELECT top (@maxResult) Total.[Count], {1} FROM Total, {2}", m_limit.To, selectQuery.SelectPart, selectQuery.FromPart);
      }
      else
      {
        result = string.Format(
@"
declare @maxResult  int;
set @maxResult = {0};

WITH Total AS
(
SELECT count(*) as [Count] FROM {2} WHERE {3}
)
SELECT top (@maxResult) Total.[Count], {1} FROM Total, {2} WHERE {3}", m_limit.To, selectQuery.SelectPart, selectQuery.FromPart, selectQuery.WherePart);
      }

      if (!string.IsNullOrWhiteSpace(selectQuery.OrderPart))
        result = string.Format("{0} ORDER BY {1}", result, selectQuery.OrderPart);

      return result;
    }

<iframe> elements have a load event for that.

How you listen to that event is up to you, but generally the best way is to:

1) create your iframe programatically

It makes sure your load listener is always called by attaching it before the iframe starts loading.

<script>
var iframe = document.createElement('iframe');
iframe.onload = function() { alert('myframe is loaded'); }; // before setting 'src'
iframe.src = '...'; 
document.body.appendChild(iframe); // add it to wherever you need it in the document
</script>

2) inline javascript, is another way that you can use inside your HTML markup.

<script>
function onMyFrameLoad() {
  alert('myframe is loaded');
};
</script>

<iframe id="myframe" src="..." onload="onMyFrameLoad(this)"></iframe>

3) You may also attach the event listener after the element, inside a <script> tag, but keep in mind that in this case, there is a slight chance that the iframe is already loaded by the time you get to adding your listener. Therefore it's possible that it will not be called (e.g. if the iframe is very very fast, or coming from cache).

<iframe id="myframe" src="..."></iframe>

<script>
document.getElementById('myframe').onload = function() {
  alert('myframe is loaded');
};
</script>

Also see my other answer about which elements can also fire this type of load event

I always use nvarchar as it allows whatever I'm building to withstand pretty much any data I throw at it. My CMS system does Chinese by accident, because I used nvarchar. These days, any new applications shouldn't really be concerned with the amount of space required.

This may be the good solution for you: change the code like this very little change

.box{
    position: relative; 
}
.box:hover .hidden{
    opacity: 1;
    width:500px;
}
.box .hidden{
    background: yellow;
    height: 334px; 
    position: absolute;
    top: 0;
    left: 0;
    width: 0;
    opacity: 0;
    transition: all 1s ease;
}

See demo here

Add this line to your method, If you are using a API.

HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*"); 

given your example above - to find processes attached to shmid 98306

lsof | egrep "98306|COMMAND"

The following code works well (On FireFox, IE and Chrome) :

var display_out = "This is line 1" + "<br>" + "This is line 2";

document.getElementById("demo").innerHTML = display_out;

Many problems here

I've set up a fiddle that works for you: http://jsfiddle.net/w9kSU/

$('.majorpointslegend').click(function(){
    if($(this).text()=='Expand'){
        $('#mylist').show();
        $(this).text('Colapse');
    }else{
        $('#mylist').hide();
        $(this).text('Expand');
    }
});

You probably have to add a class/id to and then make another CSS declaration that hides it as well.

It's notable to understand that if you'd like to conditionally add attributes you can also add a dynamic declaration:

<input v-bind="attrs" />

where attrs is declared as an object:

data() {
    return {
        attrs: {
            required: true,
            type: "text"
        }
    }
}

Which will result in:

<input required type="text"/>

Ideal in cases with multiple attributes.

You could also position the hidden div off the screen with a negative margin rather than using display:none, much like a the text indent image replacement technique.

eg.

position:absolute;
left:  -2000px;
top: 0;

This way the height() is still available.

Use ioutil.ReadFile:

func ReadFile(filename string) ([]byte, error)

ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported.

You will get a []byte instead of a string. It can be converted if really necessary:

s := string(buf)

In ~/Views/ViewStart.cshtml:

@{
    Layout = Request.IsAjaxRequest() ? null : "~/Views/Shared/_Layout.cshtml";
}

and in the controller:

public ActionResult Index()
{
    return View();
}

if you are using .bind(this), try this:

let index = Array.from(evt.target.parentElement.children).indexOf(evt.target);

$(this.pagination).find("a").on('click', function(evt) {
        let index = Array.from(evt.target.parentElement.children).indexOf(evt.target);

        this.goTo(index);
    }.bind(this))

f=open(file,"r")
lines=f.readlines()
result=[]
for x in lines:
    result.append(x.split(' ')[1])
f.close()

You can do the same using a list comprehension

print([x.split(' ')[1] for x in open(file).readlines()])

Docs on split()

string.split(s[, sep[, maxsplit]])

Return a list of the words of the string s. If the optional second argument sep is absent or None, the words are separated by arbitrary strings of whitespace characters (space, tab, newline, return, formfeed). If the second argument sep is present and not None, it specifies a string to be used as the word separator. The returned list will then have one more item than the number of non-overlapping occurrences of the separator in the string.

So, you can omit the space I used and do just x.split() but this will also remove tabs and newlines, be aware of that.

I have a helper method for this in my System.Web.UI.Page class

protected T FindControlFromMaster<T>(string name) where T : Control
{
     MasterPage master = this.Master;
     while (master != null)
     {
         T control = master.FindControl(name) as T;
         if (control != null)
             return control;

         master = master.Master;
     }
     return null;
}

then you can access using below code.

Label lblStatus = FindControlFromMaster<Label>("lblStatus");
if(lblStatus!=null) 
    lblStatus.Text = "something";

Open .eclipseproduct in the product installation folder. Or open Configuration\config.ini and check property eclipse.buildId if exist.

Yes & No, but delegate pattern in Java could be thought of this way. This video tutorial is about data exchange between activity - fragments, and it has great essence of delegate sorta pattern using interfaces.

I used this after struggling for a while, it caters to the timezone offset as well:

    public double Convert_DatTime_To_UNIXDATETIME(DateTime dt)
    {
        System.DateTime from_date = new DateTime(1970, 1, 1, 0, 0, 0, 0, System.DateTimeKind.Utc);
        double unix_time_since = dt.Subtract(from_date).TotalMilliseconds;

        TimeSpan ts_offset = TimeZoneInfo.Local.GetUtcOffset(DateTime.UtcNow);

        double offset = ts_offset.TotalMilliseconds;

        return unix_time_since - offset;
    }

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

As Johannes pointed out,

for c in "string":
    #do something with c

You can iterate pretty much anything in python using the for loop construct,

for example, open("file.txt") returns a file object (and opens the file), iterating over it iterates over lines in that file

with open(filename) as f:
    for line in f:
        # do something with line

If that seems like magic, well it kinda is, but the idea behind it is really simple.

There's a simple iterator protocol that can be applied to any kind of object to make the for loop work on it.

Simply implement an iterator that defines a next() method, and implement an __iter__ method on a class to make it iterable. (the __iter__ of course, should return an iterator object, that is, an object that defines next())

See official documentation

dirname(rstudioapi::getActiveDocumentContext()$path)

works for me but if you don't want to use rstudioapi and you are not in a proyect, you can use the symbol ~ in your path. The symbol ~ refers to the default RStudio working directory (at least on Windows).

If your RStudio working directory is "D:/Documents", setwd("~/proyect1") is the same as setwd("D:/Documents/proyect1").

Once you set that, you can navigate to a subdirectory: read.csv("DATA/mydata.csv"). Is the same as read.csv("D:/Documents/proyect1/DATA/mydata.csv").

If you want to navigate to a parent folder, you can use "../". For example: read.csv("../olddata/DATA/mydata.csv") which is the same as read.csv("D:/Documents/oldata/DATA/mydata.csv")

This is the best way for me to code scripts, no matter what computer you are using.

The problem appears to be that you are reinitializing the list to an empty list in each iteration:

while choice != 0:
    ...
    a = []
    a.append(s)

Try moving the initialization above the loop so that it is executed only once.

a = []
while choice != 0:
    ...
    a.append(s)

var myCheckboxes = new Array();
$("input:checked").each(function() {
   data['myCheckboxes[]'].push($(this).val());
});

You are pushing checkboxes to wrong array data['myCheckboxes[]'] instead of myCheckboxes.push

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

A quick look through the documentation on regular expression sytanx should bring up ways to tell if it contains a lower/upper case character at some point.

Dataframes have a sort_index method which returns a copy by default. Pass inplace=True to operate in place.

import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())

Gives me:

     A
1    4
29   2
100  1
150  5
234  3

Using regexes for this purpose is the wrong approach. Since you are using python you have a really awesome library available to extract parts from HTML documents: BeautifulSoup.

The currently top-voted answer by Krzysztof Krason fails with <title>a</title><title>b</title>. Also, it ignores title tags crossing line boundaries, e.g., for line-length reasons. Finally, it fails with <title >a</title> (which is valid HTML: White space inside XML/HTML tags).

I therefore propose the following improvement:

import re

def search_title(html):
    m = re.search(r"<title\s*>(.*?)</title\s*>", html, re.IGNORECASE | re.DOTALL)
    return m.group(1) if m else None

Test cases:

print(search_title("<title   >with spaces in tags</title >"))
print(search_title("<title\n>with newline in tags</title\n>"))
print(search_title("<title>first of two titles</title><title>second title</title>"))
print(search_title("<title>with newline\n in title</title\n>"))

Output:

with spaces in tags
with newline in tags
first of two titles
with newline
  in title

Ultimately, I go along with others recommending an HTML parser - not only, but also to handle non-standard use of HTML tags.

Use column-width property of css like below

<ul style="column-width:135px">

Take a look at UrlRewriteFilter which is essentially a java-based implementation of Apache's mod_rewrite.

You'll need to extract it into ROOT folder under your Tomcat's webapps folder; you can then configure redirects to any other context within its WEB-INF/urlrewrite.xml configuration file.

The thing about classes, and setting unencumbered global variables equal to some value within the class, is that what your global variable stores is actually the reference to the memory location the value is actually stored.

What you're seeing in your output is indicative of this.

Where you might be able to see the value and use print without issue on the initial global variables you used because of the str method and how print works, you won't be able to do this with lists, because what is stored in the elements within that list is just a reference to the memory location of the value -- read up on aliases, if you'd like to know more.

Additionally, when using lists and losing track of what is an alias and what is not, you might find you're changing the value of the original list element, if you change it in an alias list -- because again, when you set a list element equal to a list or element within a list, the new list only stores the reference to the memory location (it doesn't actually create new memory space specific to that new variable). This is where deepcopy comes in handy!

Oracle as well as modern versions of Ubuntu have moved to newer versions of Java. The default for Ubuntu 20.04 is OpenJDK 11 which is good enough for most purposes.

If you really need it for running legacy programs, OpenJDK 8 is also available for Ubuntu 20.04 from the official repositories.

If you really need exactly Java 7, the best bet as of 2020 is to download a Zulu distribution. The easiest to install if you have root privileges is the .DEB version, otherwise download the .ZIP one.

Shefali's solution for UIImageView works great, but it needs a little modification:

- (void)pinch:(UIPinchGestureRecognizer *)gesture {
    if (gesture.state == UIGestureRecognizerStateEnded
        || gesture.state == UIGestureRecognizerStateChanged) {
        NSLog(@"gesture.scale = %f", gesture.scale);

        CGFloat currentScale = self.frame.size.width / self.bounds.size.width;
        CGFloat newScale = currentScale * gesture.scale;

        if (newScale < MINIMUM_SCALE) {
            newScale = MINIMUM_SCALE;
        }
        if (newScale > MAXIMUM_SCALE) {
            newScale = MAXIMUM_SCALE;
        }

        CGAffineTransform transform = CGAffineTransformMakeScale(newScale, newScale);
        self.transform = transform;
        gesture.scale = 1;
    }
}

(Shefali's solution had the downside that it did not scale continuously while pinching. Furthermore, when starting a new pinch, the current image scale was reset.)

It is possible you just need to re-configure your python path within Eclipse. See my answer to a similar question.

It seems the behavior of defer and async is browser dependent, at least on the execution phase. NOTE, defer only applies to external scripts. I'm assuming async follows same pattern.

In IE 11 and below, the order seems to be like this:

• async (could partially execute while page loading)
• none (could execute while page loading)
• defer (executes after page loaded, all defer in order of placement in file)

In Edge, Webkit, etc, the async attribute seems to be either ignored or placed at the end:

• data-pagespeed-no-defer (executes before any other scripts, while page is loading)
• none (could execute while page is loading)
• defer (waits until DOM loaded, all defer in order of placement in file)
• async (seems to wait until DOM loaded)

In newer browsers, the data-pagespeed-no-defer attribute runs before any other external scripts. This is for scripts that don't depend on the DOM.

NOTE: Use defer when you need an explicit order of execution of your external scripts. This tells the browser to execute all deferred scripts in order of placement in the file.

ASIDE: The size of the external javascripts did matter when loading...but had no effect on the order of execution.

If you're worried about the performance of your scripts, you may want to consider minification or simply loading them dynamically with an XMLHttpRequest.

I had a similar problem.

I would also look at this answer: Is there a high resolution (microsecond, nanosecond) DateTime object available for the CLR?.

About half-way down is an answer by "Robert P" with some extension functions I found useful.

Try this:

<link href="img/favicon.ico" rel="shortcut icon" type="image/x-icon" />

Whenever I have had odd issues like this, I usually sit down with a tool like WireShark and look at the raw data being passed back and forth. You might be surprised where things are being disconnected, and you are only being notified when you try and read.

Null comparison is MUCH faster than throwing and catching exception. Exceptions have significant overhead - stack trace must be assembled etc.

Exceptions should represent an unexpected state, which often doesn't represent the situation (which is when as works better).

This example made everything clear for me:
As you can see setSoTimeout prevent the program to hang! It wait for SO_TIMEOUT time! if it does not get any signal it throw exception! It means that time expired!

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketTimeoutException;

public class SocketTest extends Thread {
  private ServerSocket serverSocket;

  public SocketTest() throws IOException {
    serverSocket = new ServerSocket(8008);
    serverSocket.setSoTimeout(10000);
  }

  public void run() {
    while (true) {
      try {
        System.out.println("Waiting for client on port " + serverSocket.getLocalPort() + "...");
        Socket client = serverSocket.accept();

        System.out.println("Just connected to " + client.getRemoteSocketAddress());
        client.close();
      } catch (SocketTimeoutException s) {
        System.out.println("Socket timed out!");
        break;
      } catch (IOException e) {
        e.printStackTrace();
        break;
      }
    }
  }

  public static void main(String[] args) {
    try {
      Thread t = new SocketTest();
      t.start();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

strip() returns the string after removing leading and trailing whitespace. see doc

In your case, you may want to try replace():

string2 = string1.replace('\n', '')

For select twitter meta name , you can add a data attribute.

example :

meta name="twitter:card" data-twitterCard="" content=""
$('[data-twitterCard]').attr('content');

I think I found a really easy way to make a deep copy ArrayList. Assuming you want to copy a String ArrayList arrayA.

ArrayList<String>arrayB = new ArrayList<String>();
arrayB.addAll(arrayA);

Let me know if it doesn't work for you.

for this approach, you will need to add system.IO to your references by adding the next line of code below the other references near the top of the c# file(where the other using ****.** stand).

using System.IO;

this next code contains 2 methods of reading the text, the first will read single lines and stores them in a string variable, the second one reads the whole text and saves it in a string variable(including "\n" (enters))

both should be quite easy to understand and use.

    string pathToFile = "";//to save the location of the selected object
    private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
        OpenFileDialog theDialog = new OpenFileDialog();
        theDialog.Title = "Open Text File";
        theDialog.Filter = "TXT files|*.txt";
        theDialog.InitialDirectory = @"C:\";
        if (theDialog.ShowDialog() == DialogResult.OK)
        {
            MessageBox.Show(theDialog.FileName.ToString());
            pathToFile = theDialog.FileName;//doesn't need .tostring because .filename returns a string// saves the location of the selected object

        }

        if (File.Exists(pathToFile))// only executes if the file at pathtofile exists//you need to add the using System.IO reference at the top of te code to use this
        {
            //method1
            string firstLine = File.ReadAllLines(pathToFile).Skip(0).Take(1).First();//selects first line of the file
            string secondLine = File.ReadAllLines(pathToFile).Skip(1).Take(1).First();

            //method2
            string text = "";
            using(StreamReader sr =new StreamReader(pathToFile))
            {
                text = sr.ReadToEnd();//all text wil be saved in text enters are also saved
            }
        }
    }

To split the text you can use .Split(" ") and use a loop to put the name back into one string. if you don't want to use .Split() then you could also use foreach and ad an if statement to split it where needed.

to add the data to your class you can use the constructor to add the data like:

  public Employee(int EMPLOYEENUM, string NAME, string ADRESS, double WAGE, double HOURS)
        {
            EmployeeNum = EMPLOYEENUM;
            Name = NAME;
            Address = ADRESS;
            Wage = WAGE;
            Hours = HOURS;
        }

or you can add it using the set by typing .variablename after the name of the instance(if they are public and have a set this will work). to read the data you can use the get by typing .variablename after the name of the instance(if they are public and have a get this will work).

Following @thomas-jungblut implementation in python, i did the same for Octave. If you find something wrong please let me know and i will fix+update.

Data comes from a txt file with the following rows:

1 10 1000
2 20 2500
3 25 3500
4 40 5500
5 60 6200

think about it as a very rough sample for features [number of bedrooms] [mts2] and last column [rent price] which is what we want to predict.

Here is the Octave implementation:

%
% Linear Regression with multiple variables
%

% Alpha for learning curve
alphaNum = 0.0005;

% Number of features
n = 2;

% Number of iterations for Gradient Descent algorithm
iterations = 10000

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% No need to update after here
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

DATA = load('CHANGE_WITH_DATA_FILE_PATH');

% Initial theta values
theta = ones(n + 1, 1);

% Number of training samples
m = length(DATA(:, 1));

% X with one mor column (x0 filled with '1's)
X = ones(m, 1);
for i = 1:n
  X = [X, DATA(:,i)];
endfor

% Expected data must go always in the last column  
y = DATA(:, n + 1)

function gradientDescent(x, y, theta, alphaNum, iterations)
  iterations = [];
  costs = [];

  m = length(y);

  for iteration = 1:10000
    hypothesis = x * theta;

    loss = hypothesis - y;

    % J(theta)    
    cost = sum(loss.^2) / (2 * m);

    % Save for the graphic to see if the algorithm did work
    iterations = [iterations, iteration];
    costs = [costs, cost];

    gradient = (x' * loss) / m; % /m is for the average

    theta = theta - (alphaNum * gradient);
  endfor    

  % Show final theta values
  display(theta)

  % Show J(theta) graphic evolution to check it worked, tendency must be zero
  plot(iterations, costs);

endfunction

% Execute gradient descent
gradientDescent(X, y, theta, alphaNum, iterations);

It is time to use agg instead of apply .

When

df = pd.DataFrame( {'a':['A','A','B','B','B','C'], 'b':[1,2,5,5,4,6], 'c': [1,2,5,5,4,6]})

If you want multiple columns stack into list , result in pd.DataFrame

df.groupby('a')[['b', 'c']].agg(list)
# or 
df.groupby('a').agg(list)

If you want single column in list, result in ps.Series

df.groupby('a')['b'].agg(list)
#or
df.groupby('a')['b'].apply(list)

Note, result in pd.DataFrame is about 10x slower than result in ps.Series when you only aggregate single column, use it in multicolumns case .

So for the git merge, you can try:

• DiffMerge to visually compare and merge files on Windows, OS X and Linux.

  

• Meld, is a visual diff and merge tool.

  

• KDiff3, a diff and merge program), which compares or merges 2 or 3 text input files/dirs.
• opendiff (part of Xcode Tools on macOS), a command line utility which launches the FileMerge application from Terminal to graphically compare files or directories, including merging.

This works good for me. I have divided the screen into two halfs: 20% and 80%:

<div style="width: 20%; float:left">
   #left content in here
</div>

<div style="width: 80%; float:right">
   #right content in there
</div>

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

Following worked for me

curl -O -L  https://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz && tar xvzf sshpass-1.06.tar.gz
cd sshpass-1.06/
./configure
sudo make install

A non-jQuery solution is much like a jQuery solution:

document.querySelector('#myinput').getAttribute('type') === 'checkbox'

suppressWarnings() has already been mentioned. An alternative is to manually convert the problematic characters to NA first. For your particular problem, taRifx::destring does just that. This way if you get some other, unexpected warning out of your function, it won't be suppressed.

> library(taRifx)
> x <- as.numeric(c("1", "2", "X"))
Warning message:
NAs introduced by coercion 
> y <- destring(c("1", "2", "X"))
> y
[1]  1  2 NA
> x
[1]  1  2 NA

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

To see database name, startup;

then type show parameter db_name;

   <EditText
        android:id="@+id/edtName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter device name"
        android:maxLength="10"
        android:inputType="textFilter"
        android:singleLine="true"/>

InputType has to set "textFilter"

        android:inputType="textFilter"

Try to use the empty() function:

<xsl:if test="empty(node/ABC/node()) and empty(node/DEF/node())">
    <xsl:text>This should work</xsl:text>
</xsl:if>

This identifies ABC and DEF as empty in the sense that they do not have any child nodes (no elements, no text nodes, no processing instructions, no comments).

But, as pointed out by @Ian, your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like.

Another cause of error could be your relative position in the tree. This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node.

This usually happens when the version of one of the DLLs of the testing environment does not match the development environment.

Clean and Build your solution and take all your DLLs to the environment where the error is happening that should fix it

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);

        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

It's written as:

def my_function(self, param_one=None): # Or custom sentinel if None is vaild
    if param_one is None:
        param_one = self.one_of_the_vars

And I think it's safe to say that will never happen in Python due to the nature that self doesn't really exist until the function starts... (you can't reference it, in its own definition - like everything else)

For example: you can't do d = {'x': 3, 'y': d['x'] * 5}

Here's a more simple version. In the cell you want the date to show up just type

=Today()      

Format the cell to the date format you want and Bob's your uncle. :)

Alternative: Stream.concat()

Stream.concat(map.values().stream(), listContainer.lst.stream())

I would place this as a comment to Triptych, but I can't comment yet due to lack of rating:

Using the enumerator method to match on sub-indices in a list of tuples. e.g.

li = [(1,2,3,4), (11,22,33,44), (111,222,333,444), ('a','b','c','d'),
        ('aa','bb','cc','dd'), ('aaa','bbb','ccc','ddd')]

# want pos of item having [22,44] in positions 1 and 3:

def getIndexOfTupleWithIndices(li, indices, vals):

    # if index is a tuple of subindices to match against:
    for pos,k in enumerate(li):
        match = True
        for i in indices:
            if k[i] != vals[i]:
                match = False
                break;
        if (match):
            return pos

    # Matches behavior of list.index
    raise ValueError("list.index(x): x not in list")

idx = [1,3]
vals = [22,44]
print getIndexOfTupleWithIndices(li,idx,vals)    # = 1
idx = [0,1]
vals = ['a','b']
print getIndexOfTupleWithIndices(li,idx,vals)    # = 3
idx = [2,1]
vals = ['cc','bb']
print getIndexOfTupleWithIndices(li,idx,vals)    # = 4

You'll probably want to try textContent instead of innerHTML.

Given innerHTML will return DOM content as a String and not exclusively the "text" in the div. It's fine if you know that your div contains only text but not suitable if every use case. For those cases, you'll probably have to use textContent instead of innerHTML

For example, considering the following markup:

<div id="test">
  Some <span class="foo">sample</span> text.
</div>

You'll get the following result:

var node = document.getElementById('test'),

htmlContent = node.innerHTML,
// htmlContent = "Some <span class="foo">sample</span> text."

textContent = node.textContent;
// textContent = "Some sample text."

See MDN for more details:

• textContent
• innerHTML

I think when you define a function with "var foo = function() {...};", the function is only defined after that line. In other words, try this:

var replaceHtmlEntites = (function() {
  var translate_re = /&(nbsp|amp|quot|lt|gt);/g;
  var translate = {
    "nbsp": " ",
    "amp" : "&",
    "quot": "\"",
    "lt"  : "<",
    "gt"  : ">"
  };
  return function(s) {
    return ( s.replace(translate_re, function(match, entity) {
      return translate[entity];
    }) );
  }
})();

var cleanText = text.replace(/^\xa0*([^\xa0]*)\xa0*$/g,"");
cleanText = replaceHtmlEntities(text);

Edit: Also, only use "var" the first time you declare a variable (you're using it twice on the cleanText variable).

Edit 2: The problem is the spelling of the function name. You have "var replaceHtmlEntites =". It should be "var replaceHtmlEntities ="

Just an additional note here as I found this when looking for a solution for a fixed div that I want to scroll. For my scenario I found that its preferable to take into account the padding on the div so I can hit the end exactly. So expanding on @Dr.Molle's answer I add the following

$('#flux').bind('scroll', function() {
    var scrollPosition = $(this).scrollTop() + $(this).outerHeight();
    var divTotalHeight = $(this)[0].scrollHeight 
                          + parseInt($(this).css('padding-top'), 10) 
                          + parseInt($(this).css('padding-bottom'), 10)
                          + parseInt($(this).css('border-top-width'), 10)
                          + parseInt($(this).css('border-bottom-width'), 10);

    if( scrollPosition == divTotalHeight )
    {
      alert('end reached');
    }
  });

That'll give you the precise location, including padding and borders

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

This is code in xml of how to center an ImageView, I used "layout_centerHorizontal".

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_centerHorizontal="true"
    >
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img2"
    />
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img1"
        />
</LinearLayout>

or this other example...

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center_horizontal"
    >
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img2"
    />
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img1"
        />
</LinearLayout>

On x86/x64 processors, a byte is 8 bits, and there are 256 possible binary states in 8 bits, 0 thru 255. This is how the OS translates your keyboard key strokes into letters on the screen. When you press the 'A' key, the keyboard sends a binary signal equal to the number 97 to the computer, and the computer prints a lowercase 'a' on the screen. You can confirm this in any Windows text editing software by holding an ALT key, typing 97 on the NUMPAD, then releasing the ALT key. If you replace '97' with any number from 0 to 255, you will see the character associated with that number on the system's character code page printed on the screen.

If a character is 8 bits, or 1 byte, then a WORD must be at least 2 characters, so 16 bits or 2 bytes. Traditionally, you might think of a word as a varying number of characters, but in a computer, everything that is calculable is based on static rules. Besides, a computer doesn't know what letters and symbols are, it only knows how to count numbers. So, in computer language, if a WORD is equal to 2 characters, then a double-word, or DWORD, is 2 WORDs, which is the same as 4 characters or bytes, which is equal to 32 bits. Furthermore, a quad-word, or QWORD, is 2 DWORDs, same as 4 WORDs, 8 characters, or 64 bits.

Note that these terms are limited in function to the Windows API for developers, but may appear in other circumstances (eg. the Linux dd command uses numerical suffixes to compound byte and block sizes, where c is 1 byte and w is bytes).

There is a super() in python also.

Example for how a super class method is called from a sub class method

class Dog(object):
    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self,x):
        self.moves.append('walk')
        self.moves.append('run')
        self.moves.append(x)
    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super().moves_setup("hello world")
        self.moves.append('fly')
dog = Superdog('Freddy')
print (dog.name)
dog.moves_setup()
print (dog.get_moves()) 

This example is similar to the one explained above.However there is one difference that super doesn't have any arguments passed to it.This above code is executable in python 3.4 version.

Short explanation:

If an algorithm is of T(g(n)), it means that the running time of the algorithm as n (input size) gets larger is proportional to g(n).

If an algorithm is of O(g(n)), it means that the running time of the algorithm as n gets larger is at most proportional to g(n).

Normally, even when people talk about O(g(n)) they actually mean T(g(n)) but technically, there is a difference.

More technically:

O(n) represents upper bound. T(n) means tight bound. O(n) represents lower bound.

f(x) = T(g(x)) iff f(x) = O(g(x)) and f(x) = O(g(x))

Basically when we say an algorithm is of O(n), it's also O(n²), O(n^1000000), O(2ⁿ), ... but a T(n) algorithm is not T(n²).

In fact, since f(n) = T(g(n)) means for sufficiently large values of n, f(n) can be bound within c₁g(n) and c₂g(n) for some values of c₁ and c₂, i.e. the growth rate of f is asymptotically equal to g: g can be a lower bound and and an upper bound of f. This directly implies f can be a lower bound and an upper bound of g as well. Consequently,

f(x) = T(g(x)) iff g(x) = T(f(x))

Similarly, to show f(n) = T(g(n)), it's enough to show g is an upper bound of f (i.e. f(n) = O(g(n))) and f is a lower bound of g (i.e. f(n) = O(g(n)) which is the exact same thing as g(n) = O(f(n))). Concisely,

f(x) = T(g(x)) iff f(x) = O(g(x)) and g(x) = O(f(x))

There are also little-oh and little-omega (?) notations representing loose upper and loose lower bounds of a function.

To summarize:

f(x) = O(g(x)) (big-oh) means that the growth rate of f(x) is asymptotically less than or equal to to the growth rate of g(x).

f(x) = O(g(x)) (big-omega) means that the growth rate of f(x) is asymptotically greater than or equal to the growth rate of g(x)

f(x) = o(g(x)) (little-oh) means that the growth rate of f(x) is asymptotically less than the growth rate of g(x).

f(x) = ?(g(x)) (little-omega) means that the growth rate of f(x) is asymptotically greater than the growth rate of g(x)

f(x) = T(g(x)) (theta) means that the growth rate of f(x) is asymptotically equal to the growth rate of g(x)

For a more detailed discussion, you can read the definition on Wikipedia or consult a classic textbook like Introduction to Algorithms by Cormen et al.

You can create a session:

import boto3
session = boto3.Session(
    aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY,
    aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY,
)

Then use that session to get an S3 resource:

s3 = session.resource('s3')

Well, of course, this doesn't apply to all projects. Still, QCoreApplication::applicationFilePath() never failed me in 6 years of C++/Qt development.

Of course, one should read documentation thoroughly before attempting to use it:

Warning: On Linux, this function will try to get the path from the /proc file system. If that fails, it assumes that argv[0] contains the absolute file name of the executable. The function also assumes that the current directory has not been changed by the application.

To be honest, I think that #ifdef and other solutions like that shouldn't be used in modern code at all.

I'm sure that smaller cross-platform libraries also exist. Let them encapsulate all that platform-specific stuff inside.

Quite simply the number is the precision of the timestamp, the fraction of a second held in the column:

SQL> create table t23
  2  (ts0 timestamp(0)
  3   , ts3 timestamp(3)
  4  , ts6 timestamp(6)
  5  )
  6  /

Table created.

SQL> insert into t23 values (systimestamp, systimestamp, systimestamp)
  2  /

1 row created.

SQL> select * from t23
  2  /

24-JAN-12 05.57.12.002648 AM

If we don't specify a precision then the timestamp defaults to six places.

SQL> alter table t23 add ts_def timestamp;

Table altered.

SQL> update t23      
  2  set ts_def = systimestamp
  3  /

1 row updated.

SQL> select * from t23
  2  /

Note that I'm running on Linux so my TIMESTAMP column actually gives me precision to six places i.e. microseconds. This would also be the case on most (all?) flavours of Unix. On Windows the limit is three places i.e. milliseconds. (Is this still true of the most modern flavours of Windows - citation needed).

As might be expected, the documentation covers this. Find out more.

"when you create timestamp(9) this gives you nanos right"

Only if the OS supports it. As you can see, my OEL appliance does not:

SQL> alter table t23 add ts_nano timestamp(9)
  2  /

Table altered.

SQL> update t23 set ts_nano = systimestamp(9)
  2  /

1 row updated.

SQL> select * from t23

If you are working with ASP.NET MVC, you can solve the problem by adding the MaxJsonLength to your result:

var jsonResult = Json(new
{
    draw = param.Draw,
    recordsTotal = count,
    recordsFiltered = count,
    data = result
}, JsonRequestBehavior.AllowGet);
jsonResult.MaxJsonLength = int.MaxValue;

Maybe try the Intl polyfill for IE8 or the olyfill service ?

or

https://github.com/andyearnshaw/Intl.js/

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

I like the answer of @supercobra, but I would use the const keyword as it is in ES6 already available:

//
// ===== File globals.ts    
//
'use strict';

export const sep='/';
export const version: string="22.2.2";

You are printing a formatted string. The {0} means to insert the first parameter following the format string; in this case the value associated with the key "rtf".

For String.Format, which is similar, if you had something like

//            Format string                    {0}           {1}
String.Format("This {0}.  The value is {1}.",  "is a test",  42 ) 

you'd create a string "This is a test. The value is 42".

You can also use expressions, and print values out multiple times:

//            Format string              {0} {1}  {2}
String.Format("Fib: {0}, {0}, {1}, {2}", 1,  1+1, 1+2) 

yielding "Fib: 1, 1, 2, 3"

See more at http://msdn.microsoft.com/en-us/library/txafckwd.aspx, which talks about composite formatting.

Nesting of 'a' will not be possible. However if you badly want to keep the structure and still make it work like the way you want, then override the anchor tag click in javascript /jquery .

so you can have 2 event listeners for the two and control them accordingly.

Example

public class myThread extends Thread{
     @override
     public void run(){
        while(true){
           threadCondWait();// Circle waiting...
           //bla bla bla bla
        }
     }
     public synchronized void threadCondWait(){
        while(myCondition){
           wait();//Comminucate with notify()
        }
     }

}
public class myAnotherThread extends Thread{
     @override
     public void run(){
        //Bla Bla bla
        notify();//Trigger wait() Next Step
     }

}

My educated guess is that the memory use you are seeing is not from the page content, but rather from loading UIWebView and all of it's supporting WebKit libraries. I love the UIWebView control, but it is a 'heavy' control that pulls in a very large block of code.

This code is a large sub-set of the iOS Safari browser, and likely initializes a large body of static structures.

native ES6 solution:

const pos = data.findIndex(el => el.id === ID_TO_REMOVE);
if (pos >= 0)
    data.splice(pos, 1);

if you know that the element is in the array for sure:

data.splice(data.findIndex(el => el.id === ID_TO_REMOVE), 1);

prototype:

Array.prototype.removeByProp = function(prop,val) {
    const pos = this.findIndex(x => x[prop] === val);
    if (pos >= 0)
        return this.splice(pos, 1);
};

// usage:
ar.removeByProp('id', ID_TO_REMOVE);

http://jsfiddle.net/oriadam/72kgprw5/

note: this removes the item in-place. if you need a new array use filter as mentioned in previous answers.

Class that will call the methods:

namespace myNamespace
{
    public class myClass
    {
        public static void voidMethodWithoutParameters()
        {
            // code here
        }
        public static string stringReturnMethodWithParameters(string param1, string param2)
        {
            // code here
            return "output";
        }
    }
}

Calling myClass static methods using Reflection:

var myClassType = Assembly.GetExecutingAssembly().GetType(GetType().Namespace + ".myClass");
                    
// calling my void Method that has no parameters.
myClassType.GetMethod("voidMethodWithoutParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);

// calling my string returning Method & passing to it two string parameters.
Object methodOutput = myClassType.GetMethod("stringReturnMethodWithParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, new object[] { "value1", "value1" });
Console.WriteLine(methodOutput.ToString());

Note: I don't need to instantiate an object of myClass to use it's methods, as the methods I'm using are static.

This was what was not working for me on mac. If it doesn't work try go to /usr/local/var/mysql/<your_name>.err to see detailed error logs.

It's pretty simple, if you don't mind rolling up your sleeves... /Library/Java/Home is the default for JAVA_HOME, and it's just a link that points to one of:

• /System/Library/Java/JavaVirtualMachines/1.?.?.jdk/Contents/Home
• /Library/Java/JavaVirtualMachines/jdk1.?.?_??.jdk/Contents/Home

So I wanted to change my default JVM/JDK version without changing the contents of JAVA_HOME... /Library/Java/Home is the standard location for the current JVM/JDK and that's what I wanted to preserve... it seems to me to be the easiest way to change things with the least side effects.

It's actually really simple. In order to change which version of java you see with java -version, all you have to do is some version of this:

cd /Library/Java
sudo rm Home
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home ./Home

I haven't taken the time but a very simple shell script that makes use of /usr/libexec/java_home and ln to repoint the above symlink should be stupid easy to create...

Once you've changed where /Library/Java/Home is pointed... you get the correct result:

cerebro:~ magneto$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27) Java HotSpot(TM)
64-Bit Server VM (build 25.60-b23, mixed mode)

You know, using a custom deleter isn't the best way to go, as you will have to mention it all over your code.
Instead, as you are allowed to add specializations to namespace-level classes in ::std as long as custom types are involved and you respect the semantics, do that:

Specialize std::default_delete:

template <>
struct ::std::default_delete<Bar> {
    default_delete() = default;
    template <class U>
    constexpr default_delete(default_delete<U>) noexcept {}
    void operator()(Bar* p) const noexcept { destroy(p); }
};

And maybe also do std::make_unique():

template <>
inline ::std::unique_ptr<Bar> ::std::make_unique<Bar>() {
    auto p = create();
    if (!p)
        throw std::runtime_error("Could not `create()` a new `Bar`.");
    return { p };
}

One small addition to the answer by vasekt:

The provided solution with the SocketFactoryRegistry works when using PoolingHttpClientConnectionManager.

However, connections via plain http don't work any longer then. You have to add a PlainConnectionSocketFactory for the http protocol additionally to make them work again:

Registry<ConnectionSocketFactory> socketFactoryRegistry = 
  RegistryBuilder.<ConnectionSocketFactory> create()
  .register("https", sslsf)
  .register("http", new PlainConnectionSocketFactory()).build();

The relative pathing is based on the document level of the client side i.e. the URL level of the document as seen in the browser.

If the URL of your website is: http://www.example.com/mywebsite/ then starting at the root level starts above the "mywebsite" folder path.

String newString= Arrays.toString(oldString).replace("[","").replace("]","").replace(",","").trim();

you need to use -e flag for echo then you can

echo -e "\t\t x"

echo do_shortcode('[CONTACT-US-FORM]');

Use this in your template.

If you are using the background image for the rounded corners then I would rather increase the padding style of the main div to give enough room for the rounded corners of the background image to be visible.

Try increasing the padding of the main div style:

#mainWrapperDivWithBGImage 
{   
    background: url("myImageWithRoundedCorners.jpg") no-repeat scroll 0 0 transparent;   
    height: 248px;   
    margin: 0;   
    overflow: hidden;   
    padding: 10px 10px;   
    width: 996px; 
}

P.S: I assume the rounded corners have a radius of 10px.

Here is the screenshot of the indentation issue. This is very minor, but it is strange that it seems to work so well, in your example visual.

I am also adding a screenshot of my Automator set-up...

Thanks

Update:

If I change the script slightly to:

And then select full lines in XCode, I get the desired outcome:

This callable function works perfectly, returns true for valid date. Be sure to call using a date on ISO format (yyyy-mm-dd or yyyy/mm/dd):

function validateDate(isoDate) {

    if (isNaN(Date.parse(isoDate))) {
        return false;
    } else {
        if (isoDate != (new Date(isoDate)).toISOString().substr(0,10)) {
            return false;
        }
    }
    return true;
}

I had the same issue because of the wrong order of the code statements. Maintain the below order to resolve the issue. All get methods statements first and later httpClient methods.

      HttpClient httpClient = new HttpClient();
get = new GetMethod(instanceUrl+usersEndPointUri);
get.setRequestHeader("Content-Type", "application/json");
get.setRequestHeader("Accept", "application/json");

httpClient.getParams().setParameter("http.protocol.single-cookie-header", true);
httpClient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
httpClient.executeMethod(get);

Not sure if this is official but this worked for me in typescript 2.7.1:

class Item {
   configs: Map<string, string>;
   constructor () {
     this.configs = new Map();
   }
}

In simple Map<keyType, valueType>

For those who like boost:

boost::filesystem::path mySourcePath("foo.bar");
boost::filesystem::path myTargetPath("bar.foo");

// Variant 1: Overwrite existing
boost::filesystem::copy_file(mySourcePath, myTargetPath, boost::filesystem::copy_option::overwrite_if_exists);

// Variant 2: Fail if exists
boost::filesystem::copy_file(mySourcePath, myTargetPath, boost::filesystem::copy_option::fail_if_exists);

Note that boost::filesystem::path is also available as wpath for Unicode. And that you could also use

using namespace boost::filesystem

if you do not like those long type names

Here's just a very simple check to make sure there's a valid protocol, and the domain extension must be two or more characters.

is_valid_url = ( $url ) => {

    let $url_object = null;

    try {
        $url_object = new URL( $url );
    } catch ( $error ) {
        return false;
    }

    const $protocol = $url_object.protocol;
    const $protocol_position = $url.lastIndexOf( $protocol );
    const $domain_extension_position = $url.lastIndexOf( '.' );

    return (
        $protocol_position === 0 &&
        [ 'http:', 'https:' ].indexOf( $protocol ) !== - 1 &&
        $domain_extension_position > 2 && $url.length - $domain_extension_position > 2
    );

};

Here is one solution with jQuery for browsers that don't support the placeholder attribute.

$('[placeholder]').focus(function() {
  var input = $(this);

  if (input.val() == input.attr('placeholder')) {
    input.val('');
    input.removeClass('placeholder');
  }
}).blur(function() {
  var input = $(this);

  if (input.val() == '' || input.val() == input.attr('placeholder')) {
    input.addClass('placeholder');
    input.val(input.attr('placeholder'));
  }
}).blur();

The X-Powered-By header is added by IIS to the HTTP response, so you can remove it even on server level via IIS Manager:

You can use the web.config directly:

<system.webServer>
   <httpProtocol>
     <customHeaders>
       <remove name="X-Powered-By" />
     </customHeaders>
   </httpProtocol>
</system.webServer>

Disable Main.storyboard

Normally I use selenium, which is software for testing automation. You can control a browser through a webdriver, so you will not have problems with javascripts and it is usually not very detected if you use the full version. Headless browsers can be more identified.

Please try this code.....

DataRow dr = dtPrf_Mstr.NewRow();
dtPrf_Mstr.Rows.Add(dr);
GVGLCode.DataSource = dtPrf_Mstr;
GVGLCode.DataBind();
int iCount = GVGLCode.Rows.Count;
for (int i = 0; i < iCount; i++)
{
   GVGLCode.Rows.Remove(GVGLCode.Rows[i]);
}
GVGLCode.DataBind();

Apart from what Andy mentioned, there is another difference which could be important - write-host directly writes to the host and return nothing, meaning that you can't redirect the output, e.g., to a file.

---- script a.ps1 ----
write-host "hello"

Now run in PowerShell:

PS> .\a.ps1 > someFile.txt
hello
PS> type someFile.txt
PS>

As seen, you can't redirect them into a file. This maybe surprising for someone who are not careful.

But if switched to use write-output instead, you'll get redirection working as expected.

You can pivot your DataFrame after creating:

>>> df = pd.DataFrame(data)
>>> df.pivot(index=0, columns=1, values=2)
# avg DataFrame
1      c1     c2
0               
r1  avg11  avg12
r2  avg21  avg22
>>> df.pivot(index=0, columns=1, values=3)
# stdev DataFrame
1        c1       c2
0                   
r1  stdev11  stdev12
r2  stdev21  stdev22

Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)

Do it the other way around:

$a = "1,435";
$b = str_replace( ',', '', $a );

if( is_numeric( $b ) ) {
    $a = $b;
}

The easiest would be:

$var = intval(preg_replace('/[^\d.]/', '', $var));

or if you need float:

$var = floatval(preg_replace('/[^\d.]/', '', $var));

You can also do

 Pushd "%~dp0"

Which also takes running from a unc path into consideration.

In case all your source and replacement strings are just one character long, you can simply use the TRANSLATE function:

  SELECT translate('THIS IS UPPERCASE', 'THISUP', 'thisup') 
  FROM DUAL

See the Oracle documentation for details.

I have python 2.7.3 and this solved my problem:

pip install pysqlite

Running queries on hot-standby server is somewhat tricky — it can fail, because during querying some needed rows might be updated or deleted on primary. As a primary does not know that a query is started on secondary it thinks it can clean up (vacuum) old versions of its rows. Then secondary has to replay this cleanup, and has to forcibly cancel all queries which can use these rows.

Longer queries will be canceled more often.

You can work around this by starting a repeatable read transaction on primary which does a dummy query and then sits idle while a real query is run on secondary. Its presence will prevent vacuuming of old row versions on primary.

More on this subject and other workarounds are explained in Hot Standby — Handling Query Conflicts section in documentation.

These are function annotations covered in PEP 3107. Specifically, the -> marks the return function annotation.

Examples:

>>> def kinetic_energy(m:'in KG', v:'in M/S')->'Joules': 
...    return 1/2*m*v**2
... 
>>> kinetic_energy.__annotations__
{'return': 'Joules', 'v': 'in M/S', 'm': 'in KG'}

Annotations are dictionaries, so you can do this:

>>> '{:,} {}'.format(kinetic_energy(20,3000),
      kinetic_energy.__annotations__['return'])
'90,000,000.0 Joules'

You can also have a python data structure rather than just a string:

>>> rd={'type':float,'units':'Joules','docstring':'Given mass and velocity returns kinetic energy in Joules'}
>>> def f()->rd:
...    pass
>>> f.__annotations__['return']['type']
<class 'float'>
>>> f.__annotations__['return']['units']
'Joules'
>>> f.__annotations__['return']['docstring']
'Given mass and velocity returns kinetic energy in Joules'

Or, you can use function attributes to validate called values:

def validate(func, locals):
    for var, test in func.__annotations__.items():
        value = locals[var]
        try: 
            pr=test.__name__+': '+test.__docstring__
        except AttributeError:
            pr=test.__name__   
        msg = '{}=={}; Test: {}'.format(var, value, pr)
        assert test(value), msg

def between(lo, hi):
    def _between(x):
            return lo <= x <= hi
    _between.__docstring__='must be between {} and {}'.format(lo,hi)       
    return _between

def f(x: between(3,10), y:lambda _y: isinstance(_y,int)):
    validate(f, locals())
    print(x,y)

Prints

>>> f(2,2) 
AssertionError: x==2; Test: _between: must be between 3 and 10
>>> f(3,2.1)
AssertionError: y==2.1; Test: <lambda>

you don't need to set the width of header in css, just put the background image as center using this code:

background: url("images/logo.png") no-repeat top center;

or you can just use img tag and put align="center" in the div

This works perfectly fine with me :)

Path.GetFileName(path.TrimEnd('\\')

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

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

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

If you are targeting iOS7 and already have the image split into frames you can use animatedImageNamed:duration:.

Let's say you are animating a spinner. Copy all of your frames into the project and name them as follows:

• spinner-1.png
• spinner-2.png
• spinner-3.png
• etc.,

Then create the image via:

[UIImage animatedImageNamed:@"spinner-" duration:1.0f];

From the docs:

This method loads a series of files by appending a series of numbers to the base file name provided in the name parameter. For example, if the name parameter had ‘image’ as its contents, this method would attempt to load images from files with the names ‘image0’, ‘image1’ and so on all the way up to ‘image1024’. All images included in the animated image should share the same size and scale.

if you want destroy dark background of dialog , use this

dialog.getWindow().setDimAmount(0);

What is "it" in the statement "it just says the procedure is completed"?

By default, most tools do not configure a buffer for dbms_output to write to and do not attempt to read from that buffer after code executes. Most tools, on the other hand, have the ability to do so. In SQL*Plus, you'd need to use the command set serveroutput on [size N|unlimited]. So you'd do something like

SQL> set serveroutput on size 30000;
SQL> exec print_actor_quotes( <<some value>> );

In SQL Developer, you'd go to View | DBMS Output to enable the DBMS Output window, then push the green plus icon to enable DBMS Output for a particular session.

Additionally, assuming that you don't want to print the literal "a.firstNamea.lastName" for every row, you probably want

FOR row IN quote_recs
LOOP
  DBMS_OUTPUT.PUT_LINE( row.firstName || ' ' || row.lastName );
END LOOP;

There are two ways to specify label for element:

1. Setting label's "for" attribute to element's id
2. Placing element inside label

So, the proper way to find element's label is

   var $element = $( ... )

   var $label = $("label[for='"+$element.attr('id')+"']")
   if ($label.length == 0) {
     $label = $element.closest('label')
   }

   if ($label.length == 0) {
     // label wasn't found
   } else {
     // label was found
   }

Have you tried just going: git commit -m "Message here"

So in your case:

git commit -m "Form validation added"

After you've added your files of course.

Do

apachectl -k graceful

Check this link for more information : http://www.electrictoolbox.com/article/apache/restart-apache/

For negative integer value, SIGNED is used and for non-negative integer value, UNSIGNED is used. It always suggested to use UNSIGNED for id as a PRIMARY KEY.

Ookii folder dialog can be found at Nuget.

{
    textBoxFolderPath.Text = dialog.SelectedPath;
}

How you are running your script? If you did with

$ sh myscript

you should try:

$ bash myscript

or, if the script is executable:

$ ./myscript

sh and bash are two different shells. While in the first case you are passing your script as an argument to the sh interpreter, in the second case you decide on the very first line which interpreter will be used.

According to pip documentation example 3:

pip install --upgrade django

But based on my experience, using this method will also upgrade any package related to it. Example:

Assume you want to upgrade somepackage that require Django >= 1.2.4 using this kind of method it will also upgrade somepackage and django to the newest update. Just to be safe, do:

# Assume you want to keep Django 1.2.4
pip install --upgrade somepackage django==1.2.4

Doing this will upgrade somepackage and keeping Django to the 1.2.4 version.

Add .+? in <[^>]*> and try this regex (base on this):

<[^>].+?>

c# .net regex demo

To insert/append to a dictionary

{"0": {"travelkey":"value", "travelkey2":"value"},"1":{"travelkey":"value","travelkey2":"value"}} 

travel_dict={} #initialize dicitionary 
travel_key=0 #initialize counter

if travel_key not in travel_dict: #for avoiding keyerror 0
    travel_dict[travel_key] = {}
travel_temp={val['key']:'no flexible'}  
travel_dict[travel_key].update(travel_temp) # Updates if val['key'] exists, else adds val['key']
travel_key=travel_key+1

Assuming you're on at least 3.2, there's a built in for this:

int.from_bytes( bytes, byteorder, *, signed=False )

...

The argument bytes must either be a bytes-like object or an iterable producing bytes.

The byteorder argument determines the byte order used to represent the integer. If byteorder is "big", the most significant byte is at the beginning of the byte array. If byteorder is "little", the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value.

The signed argument indicates whether two’s complement is used to represent the integer.

## Examples:
int.from_bytes(b'\x00\x01', "big")                         # 1
int.from_bytes(b'\x00\x01', "little")                      # 256

int.from_bytes(b'\x00\x10', byteorder='little')            # 4096
int.from_bytes(b'\xfc\x00', byteorder='big', signed=True)  #-1024

Bulk inserts in Mongoose can be done with .insert() unless you need to access middleware.

It is the container of the Grid that is imposing on its width. In this case, that's a ListBoxItem, which is left-aligned by default. You can set it to stretch as follows:

<ListBox>
    <!-- other XAML omitted, you just need to add the following bit -->
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="HorizontalAlignment" Value="Stretch"/>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

The Real Solution:

add <!DOCTYPE something> to the begining of each problematic XML,

after the xml tag <?xml version="1.0" encoding="utf-8"?>

you can write anything for doctype, but basically it's supposed to be manifest, activity, etc. from what I understand

Let's say you have a Dictionary called fooDictionary

fooDictionary.Values.ToList().IndexOf(someValue);

Values.ToList() converts your dictionary values into a List of someValue objects.

IndexOf(someValue) searches your new List looking for the someValue object in question and returns the Index which would match the index of the Key/Value pair in the dictionary.

This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.

This does not however account for the issue that there may be several matching "someValue" objects.

There is also a plot.background option in addition to panel.background:

df <- data.frame(y=d,x=1)
p <- ggplot(df) + stat_boxplot(aes(x = x,y=y)) 
p <- p + opts(
    panel.background = theme_rect(fill = "transparent",colour = NA), # or theme_blank()
    panel.grid.minor = theme_blank(), 
    panel.grid.major = theme_blank(),
    plot.background = theme_rect(fill = "transparent",colour = NA)
)
#returns white background
png('tr_tst2.png',width=300,height=300,units="px",bg = "transparent")
print(p)
dev.off()

For some reason, the uploaded image is displaying differently than on my computer, so I've omitted it. But for me, I get a plot with an entirely gray background except for the box part of the boxplot which is still white. That can be changed using the fill aesthetic in the boxplot geom as well, I believe.

Edit

ggplot2 has since been updated and the opts() function has been deprecated. Currently, you would use theme() instead of opts() and element_rect() instead of theme_rect(), etc.

you can go:

var cp = require('child_process');

and then:

cp.exec('./myScript.sh', function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a command in your $SHELL.
Or go

cp.spawn('./myScript.sh', [args], function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a file WITHOUT a shell.
Or go

cp.execFile();

which is the same as cp.exec() but doesn't look in the $PATH.

You can also go

cp.fork('myJS.js', function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a javascript file with node.js, but in a child process (for big programs).

EDIT

You might also have to access stdin and stdout with event listeners. e.g.:

var child = cp.spawn('./myScript.sh', [args]);
child.stdout.on('data', function(data) {
  // handle stdout as `data`
});

Adding the width attribute to the [svg] tag (by editing the svg source XML) worked for me: eg:

<!-- This didn't render -->
<svg version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg">
...  
</svg>

<!-- This did -->
<svg version="1.1" baseProfile="full" width="1000" xmlns="http://www.w3.org/2000/svg">
...  
</svg>

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

For other such DOM traversal queries, check out the documentation on traversing the DOM.

Try the following:

MemoryStream stream = new MemoryStream();
Bitmap bitmap = new Bitmap();
bitmap.Save(stream, ImageFormat.Jpeg);

byte[] byteArray = stream.GetBuffer();

Make sure you are using:

System.Drawing & using System.Drawing.Imaging;

You can do it with animate function in jQuery.

$({ countNum: $('.code').html() }).animate({ countNum: 4000 }, {
    duration: 8000,
    easing: 'linear',
    step: function () {
        $('.yourelement').html(Math.floor(this.countNum));
    },
    complete: function () {
        $('.code').html(this.countNum);
        //alert('finished');
   }
});

Demo

This problem is just because you have declared the column in CHAR, VARCHAR or TEXT datatype. Just change the datatype to INT, BIGINT etc. This is will solved the problem of your custom ordering.

Try using java.util.TreeSet that implements SortedSet.

To quote the doc:

"The elements are ordered using their natural ordering, or by a Comparator provided at set creation time, depending on which constructor is used"

Note that add, remove and contains has a time cost log(n).

If you want to access the content of the set as an Array, you can convert it doing:

YourType[] array = someSet.toArray(new YourType[yourSet.size()]); 

This array will be sorted with the same criteria as the TreeSet (natural or by a comparator), and in many cases this will have a advantage instead of doing a Arrays.sort()

Below code for best examples for nested loops, while using two for loops please remember the output of the first loop is input for the second loop. Loop termination also important while using the nested loops

for x in range(1, 10, 1):
     for y in range(1,x):
             print y,
        print
OutPut :

1 2 3 4 5
1 2 3 4 5 6

dwkd's answer mostly worked for me in Entity Framework core, except when I saw this exception:

InvalidOperationException: The instance of entity type 'Customer' cannot be tracked because another instance with the same key value for {'Id'} is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached. Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the conflicting key values.

To avoid the exception, I updated the code:

Customer customer = context.Customers.Local.First(c => c.Id == id);
if (customer == null) {
    customer = new Customer () { Id = id };
    context.Customers.Attach(customer);
}
context.Customers.Remove(customer);
context.SaveChanges();

Following what @viveknuna suggested, I upgraded to the latest version of node.js and npm using the downloaded installer. I also installed the latest version of yarn using a downloaded installer. Then, as you can see below, I upgraded angular-cli and typescript. Here's what that process looked like:

Yes you can do it with String.format:

String result = String.format("%.2f", 10.0 / 3.0);
// result:  "3.33"

result = String.format("%.3f", 2.5);
// result:  "2.500"

This was added to the upgrade documentation on Dec 29, 2015, so if you upgraded before then you probably missed it.

When fetching any attribute from the model it checks if that column should be cast as an integer, string, etc.

By default, for auto-incrementing tables, the ID is assumed to be an integer in this method:

https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L2790

So the solution is:

class UserVerification extends Model
{
    protected $primaryKey = 'your_key_name'; // or null

    public $incrementing = false;

    // In Laravel 6.0+ make sure to also set $keyType
    protected $keyType = 'string';
}

This code seems to work fine (see this jsfiddle). Is your javascript defined before your body? When the browser reads onclick="myFunction()" it has to know what myFunction is.

I really enjoy a new literal string interpolation in Python 3.6+:

line_new = f'{word[0]:>12}  {word[1]:>12}  {word[2]:>12}'

Reference: PEP 498 -- Literal String Interpolation

You could write a method that would do it directly via sql I suppose.

Would look something like this:

Variables:

$store_id = 1;
$product_id = 1234;
$attribute_code = 'manufacturer';

Query:

SELECT value FROM eav_attribute_option_value WHERE option_id IN (
    SELECT option_id FROM eav_attribute_option WHERE FIND_IN_SET(
        option_id, 
        (SELECT value FROM catalog_product_entity_varchar WHERE
            entity_id = '$product_id' AND 
            attribute_id = (SELECT attribute_id FROM eav_attribute WHERE
                attribute_code='$attribute_code')
        )
    ) > 0) AND
    store_id='$store_id';

You would have to get the value from the correct table based on the attribute's backend_type (field in eav_attribute) though so it takes at least 1 additional query.

The XP Support Tools (which can be installed from your XP CD) come with a program called setx.exe:

C:\Program Files\Support Tools>setx /?

SETX: This program is used to set values in the environment
of the machine or currently logged on user using one of three modes.

1) Command Line Mode: setx variable value [-m]
   Optional Switches:
    -m  Set value in the Machine environment. Default is User.

...
For more information and example use: SETX -i

I think Windows 7 actually comes with setx as part of a standard install.

You have to call next() before you can start reading values from the first row. beforeFirst puts the cursor before the first row, so there's no data to read.

Regarding the cygwin1.dll not found error, a solution I have used for at least 8 years is to add the Cygwin bin directories to the end of my %PATH% in My Computer -> Properties -> Advanced -> Environment Variables. I add them to the end of the path so in my normal work, they are searched last, minimizing the possibility of conflicts (in fact, I have had no problems with conflicts in all this time).

When you invoke the Cygwin Bash Shell, those directories get prepended to the %PATH% so everything works as intended in that environment as well.

When not running in Cygwin shell, my %PATH% is:

Path=c:\opt\perl\bin; \
     ...
     C:\opt\cygwin\bin; \
     C:\opt\cygwin\usr\bin; \
     C:\opt\cygwin\usr\local\bin;

This way, for example, ActiveState Perl's perl is found first when I am not in a Cygwin Shell, but the Cygwin perl is found when I am working in the Cygwin Shell.

When you annotate a parameter with @RequestHeader, the parameter retrieves the header information. So you can just do something like this:

@RequestHeader("Accept")

to get the Accept header.

So from the documentation:

@RequestMapping("/displayHeaderInfo.do")
public void displayHeaderInfo(@RequestHeader("Accept-Encoding") String encoding,
                              @RequestHeader("Keep-Alive") long keepAlive)  {

}

The Accept-Encoding and Keep-Alive header values are provided in the encoding and keepAlive parameters respectively.

And no worries. We are all noobs with something.

Well in general index is a B-tree. There are two types of indexes: clustered and nonclustered.

Clustered index creates a physical order of rows (it can be only one and in most cases it is also a primary key - if you create primary key on table you create clustered index on this table also).

Nonclustered index is also a binary tree but it doesn't create a physical order of rows. So the leaf nodes of nonclustered index contain PK (if it exists) or row index.

Indexes are used to increase the speed of search. Because the complexity is of O(log N). Indexes is very large and interesting topic. I can say that creating indexes on large database is some kind of art sometimes.

I arrived here because I thought I should check in SO if there are adequate answers, after a syntax error that gave me this error, or if I could possibly post an answer myself.

OK, the answers here explain what this error is, so not much more to say, but nevertheless I will give my 2 cents using my words:

This error is caused by the fact that you basically generate a new table with your subquery for the FROM command.

That's what a derived table is, and as such, it needs to have an alias (actually a name reference to it).

So given the following hypothetical query:

SELECT id, key1
FROM (
    SELECT t1.ID id, t2.key1 key1, t2.key2 key2, t2.key3 key3
    FROM table1 t1 
    LEFT JOIN table2 t2 ON t1.id = t2.id
    WHERE t2.key3 = 'some-value'
) AS tt

So, at the end, the whole subquery inside the FROM command will produce the table that is aliased as tt and it will have the following columns id, key1, key2, key3.

So, then with the initial SELECT from that table we finally select the id and key1 from the tt.

I modified /etc/php.ini

[Date] ; Defines the default timezone used by the date functions ; http://php.net/date.timezone date.timezone =('Asia/kolkata')

and now working fine.

I suspect that the variable ${file.name} is not substituted correctly. As a result, the value of log4j.appender.FILE.File becomes logs/. As such, Java tries to create a log file named logs/, but probably it is an existing directory, so you get the exception.

As a quick remedy, change the log4j.appender.FILE.File setting to point to file by absolute path, for example /tmp/mytest.log. You should not get an exception.

After that you can proceed to debugging why ${file.name} is not replaced correctly in your runtime environment.

Since every object in JavaScript behaves like - and is generally implemented as - a hashtable, I just go with that...

var hashSweetHashTable = {};

Use $HTTP_RAW_POST_DATA instead of $_POST.

It will give you POST data as is.

You will be able to decode it using json_decode() later.

Since today I know it: the best thing for text extraction from PDFs is TET, the text extraction toolkit. TET is part of the PDFlib.com family of products.

PDFlib.com is Thomas Merz's company. In case you don't recognize his name: Thomas Merz is the author of the "PostScript and PDF Bible".

TET's first incarnation is a library. That one can probably do everything Budda006 wanted, including positional information about every element on the page. Oh, and it can also extract images. It recombines images which are fragmented into pieces.

pdflib.com also offers another incarnation of this technology, the TET plugin for Acrobat. And the third incarnation is the PDFlib TET iFilter. This is a standalone tool for user desktops. Both these are free (as in beer) to use for private, non-commercial purposes.

And it's really powerful. Way better than Adobe's own text extraction. It extracted text for me where other tools (including Adobe's) do spit out garbage only.

I just tested the desktop standalone tool, and what they say on their webpage is true. It has a very good commandline. Some of my "problematic" PDF test files the tool handled to my full satisfaction.

This thing will from now on be my recommendation for every sophisticated and challenging PDF text extraction requirements.

TET is simply awesome. It detects tables. Inside tables, it identifies cells spanning multiple columns. It identifies table rows and contents of each table cell separately. It deals very well with hyphenations: it removes hyphens and restores complete words. It supports non-ASCII languages (including CJK, Arabic and Hebrew). When encountering ligatures, it restores the original characters...

Give it a try.

//Page load starts here

var json = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(new

});

var json2 = "{\"api_key\":\"my key\",\"action\":\"categories\",\"store_id\":\"my store\",\"user\" : {\"id\" : 12345,\"screen_name\" : \"twitpicuser\"}}";
var list = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<FooBar>(json);
var list2 = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<FooBar>(json2);

string a = list2.action;
var b = list2.user;
string c = b.screen_name;

//Page load ends here

{
    public string api_key { get; set; }

{
    public int id { get; set; }
    public string screen_name { get; set; }
}

Since then, and only recently, Microsoft pushes Excel Web App as alternative (a poor alternative IMHO)

As a side note: Microsoft also deprecated the other way round, i.e. embedding the webbrowser control into an excel sheet, see adding-web-browser-control-to-excel-2013. As an alternative Microsoft offers Office Apps (a very limited alternative with respect to interfacing Excel and IE)

I have created a class which adds a border to imageView h. Use this class instead of UIImageView.I have given a padding of 4. You can give as per your wish.

class UIBorderImageView: UIView {

private lazy var imageView: UIImageView = {
    let imageView = UIImageView()
    imageView.contentMode = .scaleAspectFit
    imageView.translatesAutoresizingMaskIntoConstraints = false
    return imageView
}()

override init(frame: CGRect) {
    super.init(frame: frame)
    self.backgroundColor = UIColor.White()
    self.layer.borderColor = UIColor.GreyMedium().cgColor
    self.layer.borderWidth = 1.0
    self.layer.cornerRadius = 4.0
    self.layer.masksToBounds = true
    self.setUpViews()
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

private func setUpViews(){
    self.addSubview(imageView)
    self.addConstraintsWithFormat(format: "H:|-4-[v0]-4-|", views: imageView)
    self.addConstraintsWithFormat(format: "V:|-4-[v0]-4-|", views: imageView)
}

func configureImageViewWith(image:UIImage){
    self.imageview.image = image 
}}

You can have a pair of extension methods to make this task easier:

public static string ToDelimitedString<T>(this IEnumerable<T> lst, string separator = ", ")
{
    return lst.ToDelimitedString(p => p, separator);
}

public static string ToDelimitedString<S, T>(this IEnumerable<S> lst, Func<S, T> selector, 
                                             string separator = ", ")
{
    return string.Join(separator, lst.Select(selector));
}

So now just:

new int[] { 1, 2, 3, 4, 5 }.ToDelimitedString();

I ran into the same issue. When I ran my Unit Test on C++ code, I got an error that said "Cannot find or open the PDB file".

Logs

When I looked at the Output log in Visual Studio, I saw that it was looking in the wrong folder. I had renamed the WinUnit folder, but something in the WinUnit code was looking for the PDB file using the old folder name. I guess they hard-coded it.

Found the Problem

When I first downloaded and unzipped the WinUnit files, the main folder was called "WinUnit-1.2.0909.1". After I unzipped the file, I renamed the folder to "WinUnit" since it's easier to type during Visual Studio project setup. But apparently this broke the ability to find the PDB file, even though I setup everything according to the WinUnit documentation.

My Fix

I changed the folder name back to the original, and it works.

Weird.

The only option I can think of is using width:100%. If you want to have a padding on the input field too, than just place a container label around it, move the formatting to that label instead, while also specify the padding to the label. Input fields are rigid.

When the C# 5 CTP was introduced, you certainly could mark Main with async... although it was generally not a good idea to do so. I believe this was changed by the release of VS 2013 to become an error.

Unless you've started any other foreground threads, your program will exit when Main completes, even if it's started some background work.

What are you really trying to do? Note that your GetList() method really doesn't need to be async at the moment - it's adding an extra layer for no real reason. It's logically equivalent to (but more complicated than):

public Task<List<TvChannel>> GetList()
{
    return new GetPrograms().DownloadTvChannels();
}

If you want to change the user at git Bash .You just need to configure particular user and email(globally) at the git bash.

$ git config --global user.name "abhi"
$ git config --global user.email "[email protected]"

Note: No need to delete the user from Keychain .

My solution was to add a space between the $ and the {.

For example:

@Value("${project.ftp.adresse}")

becomes

@Value("$ {project.ftp.adresse}")

Try this:

/^(\/([^/]+\/)*)(.*)$/

It will leave the trailing slash on the path, though.

A clone is simply a copy of a repository. On the surface, its result is equivalent to svn checkout, where you download source code from some other repository. The difference between centralized VCS like Subversion and DVCSs like Git is that in Git, when you clone, you are actually copying the entire source repository, including all the history and branches. You now have a new repository on your machine and any commits you make go into that repository. Nobody will see any changes until you push those commits to another repository (or the original one) or until someone pulls commits from your repository, if it is publicly accessible.

A branch is something that is within a repository. Conceptually, it represents a thread of development. You usually have a master branch, but you may also have a branch where you are working on some feature xyz, and another one to fix bug abc. When you have checked out a branch, any commits you make will stay on that branch and not be shared with other branches until you merge them with or rebase them onto the branch in question. Of course, Git seems a little weird when it comes to branches until you look at the underlying model of how branches are implemented. Rather than explain it myself (I've already said too much, methinks), I'll link to the "computer science" explanation of how Git models branches and commits, taken from the Git website:

http://eagain.net/articles/git-for-computer-scientists/

A fork isn't a Git concept really, it's more a political/social idea. That is, if some people aren't happy with the way a project is going, they can take the source code and work on it themselves separate from the original developers. That would be considered a fork. Git makes forking easy because everyone already has their own "master" copy of the source code, so it's as simple as cutting ties with the original project developers and doesn't require exporting history from a shared repository like you might have to do with SVN.

EDIT: since I was not aware of the modern definition of "fork" as used by sites such as GitHub, please take a look at the comments and also Michael Durrant's answer below mine for more information.

While sourceSets allows you to include entire directory structures, there's no way to exclude parts of it in Android Studio (as of version 1.2), as described here: Android Studio Exclude Class from build?

Until Android Studio gets updated to support include/exclude directives for Android sources, Symlinks work quite well. If you're using Windows, native tools such as junction or mklink can accomplish the equivalent of Un*x symlinks. CygWin can also create these with a little coersion. See: Git Symlinks in Windows and How to make symbolic link with cygwin in Windows 7
