I set width and height of a container to double.infinity like so:

Container(
        width: double.infinity,
        height: double.infinity,
        child: //your child
)

Simple, just wrap it up in a table div...

The HTML:

<div class="fake-table">
   <div class="left-side">
     some text
   </div>
   <div class="right-side">
     My Navigation or something
   </div>
</div>

The CSS:

<style>

 .fake-table{display:table;width:100%;height:100%;}
 .left-size{width:30%;height:100%;}
 .left-size{width:70%;height:100%;}

</style>

You can set HorizontalAlignment to Left, set your MaxWidth and then bind Width to the ActualWidth of the parent element:

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <StackPanel Name="Container">   
    <TextBox Background="Azure" 
    Width="{Binding ElementName=Container,Path=ActualWidth}"
    Text="Hello" HorizontalAlignment="Left" MaxWidth="200" />
  </StackPanel>
</Page>

I do the following:

from selenium import webdriver
browser = webdriver.Chrome('C:\chromedriver.exe')
browser.maximize_window()

Based on your patterns one improvement would be to change to using StartsWith instead of Contains. StartsWith need only iterate through each string until it finds the first mismatch instead of having to restart the search at every character position when it finds one.

Also, based on your patterns, it looks like you may be able to extract the first part of the path for myString, then reverse the comparison -- looking for the starting path of myString in the list of strings rather than the other way around.

string[] pathComponents = myString.Split( Path.DirectorySeparatorChar );
string startPath = pathComponents[0] + Path.DirectorySeparatorChar;

return listOfStrings.Contains( startPath );

EDIT: This would be even faster using the HashSet idea @Marc Gravell mentions since you could change Contains to ContainsKey and the lookup would be O(1) instead of O(N). You would have to make sure that the paths match exactly. Note that this is not a general solution as is @Marc Gravell's but is tailored to your examples.

Sorry for the C# example. I haven't had enough coffee to translate to VB.

In VS2019, the project property page, TypeScript Build tab has a setting (dropdown) for "Module System". When I changed that from "ES2015" to CommonJS, then VS2019 IDE stopped complaining that it could find neither axios nor redux-thunk (TS2307).

Editing the first line of this file worked to me:

The correct pattern is to call the Redirect overload with endResponse=false and make a call to tell the IIS pipeline that it should advance directly to the EndRequest stage once you return control:

Response.Redirect(url, false);
Context.ApplicationInstance.CompleteRequest();

This blog post from Thomas Marquardt provides additional details, including how to handle the special case of redirecting inside an Application_Error handler.

I think the best way to solve this problem is:

l = [1, 2, 3, 0, 0, 1]
while 0 in l:
    l.remove(0)

Instead of iterating over list I remove 0 until there aren't any 0 in list

The solution for PyMongo (Python mongo):

db.example.update({}, {'$unset': {'tags.words':1}}, multi=True);

This is what I've been doing if you need to do something iterative... but it would be wise to look for set operations first. Also, do not do this because you don't want to learn cursors.

select top 1000 TableID
into #ControlTable 
from dbo.table
where StatusID = 7

declare @TableID int

while exists (select * from #ControlTable)
begin

    select top 1 @TableID = TableID
    from #ControlTable
    order by TableID asc

    -- Do something with your TableID

    delete #ControlTable
    where TableID = @TableID

end

drop table #ControlTable

This is an altered version of @Martin Thoma's answer for GTK3. I found that the original solution resulted in the process never ending and my terminal hung when I called the script. Changing the script to the following resolved the issue for me.

#!/usr/bin/python3

from gi.repository import Gtk, Gdk
import sys
from time import sleep

class Hello(Gtk.Window):

    def __init__(self):
        super(Hello, self).__init__()

        clipboardText = sys.argv[1]
        clipboard = Gtk.Clipboard.get(Gdk.SELECTION_CLIPBOARD)
        clipboard.set_text(clipboardText, -1)
        clipboard.store()


def main():
    Hello()



if __name__ == "__main__":
    main()

You will probably want to change what clipboardText gets assigned to, in this script it is assigned to the parameter that the script is called with.

On a fresh ubuntu 16.04 installation, I found that I had to install the python-gobject package for it to work without a module import error.

Its not possible thats the whole point of hashing. You can however bruteforce by going through all possibilities (using all possible digits characters in every possible order) and hashing them and checking for a collision.

for more information on hashing and MD5 etc see: http://en.wikipedia.org/wiki/MD5 , http://en.wikipedia.org/wiki/Hash_function , http://en.wikipedia.org/wiki/Cryptographic_hash_function and http://onin.com/hhh/hhhexpl.html

I myself created my own app to do this, its open source you can check the link: http://sourceforge.net/projects/jpassrecovery/ and of course the source. Here is the source for easy access it has a basic implementation in the comments:

you would use it like:

      hb.setMaxLength(5); hb.setMinLength(1);

     hb.addSpecialCharacters(); hb.addUpperCaseLetters();

      Thread thread = new Thread(new Runnable() {

      @Override public void run() { hb.tryBruteForce(); } });

      thread.start();

      while (!hb.isFound()) { System.out.println("Hash: " +
      hb.getGeneratedHash()); System.out.println("Number of Possibilities: " +
      hb.getNumberOfPossibilities()); System.out.println("Checked hashes: " +
     hb.getCounter()); System.out.println("Estimated hashes left: " +
     hb.getRemainder()); }

     System.out.println("Found " + hb.getType() + " hash collision: " +
     hb.getGeneratedHash() + " password is: " + hb.getPassword());

In my opinion the best is to create a new class which constructor is the function you need, e.g.:

public class pairReturn{
        //name your parameters:
        public int sth1;
        public double sth2;
        public pairReturn(int param){
            //place the code of your function, e.g.:
            sth1=param*5;
            sth2=param*10;
        }
    }

Then simply use the constructor as you would use the function:

pairReturn pR = new pairReturn(15);

and you can use pR.sth1, pR.sth2 as "2 results of the function"

there are some solution to solve this issue : 1 ) run your command prompt as "administrator".

if first solution doesn't solve your problem try this one :

2 ) open a command prompt as administrator paste following line of code and hit enter :

npm install --global --production windows-build-tools

If you're not opposed to including a library in your project, lodash has a repeat function.

_.repeat('*', 3);
// ? '***

https://lodash.com/docs#repeat

Add the following line in your Dockerfile then rebuild the docker image.

RUN apt-get update && apt-get install -y vim

Use Xcode's native Color Literals feature to add hex colors easily and natively.

Type Color Literal into your code and let Xcode autocomplete do the rest.

The color picker UI will allow you to paste in a Hex Color: #FF9300

The git diff of the macro will show RGB values rather than hex:

let orange = #colorLiteral(red: 1, green: 0.5763723254, blue: 0, alpha: 1)

But it's still an easy way to paste in hex without any 3rd party tools or extensions.

Oops, the sed command has to precede the tidy command of course:

echo "$htmlstr" | 
sed '/type="global"/d' |
tidy -q -c -wrap 0 -numeric -asxml -utf8 --merge-divs yes --merge-spans yes 2>/dev/null |
xmlstarlet sel -N x="http://www.w3.org/1999/xhtml" -T -t -m "//x:table" -v '@name' -n

check man page and you will get.

At last, Visual Studio 2017 allows the user to import an entire directory with a single click. Visual Studio 2017 has a new functionality "Open Folder" that allows opening the entire folder, even without the need to save it as solution. The source code can be imported using the following methods.

1. Menu File ? Open ? *Folder (Ctrl + Shift + O)
2. devenv.exe <source folder>

It even supports building and debugging CMake projects.

Bring your C++ codebase to Visual Studio with “Open Folder”

Ok,

I managed to solve this tricky issue. The thing was like I was using FrameLayout. Don't know why but it came to my mind that may be the icon would be getting hidden behind some other view.

I tried putting the icon at the end of my layout and now I am able to see the Toast as well as the Log.

Thank you everybody for taking time to solve the issue.. Was surely tricky..

You should use return as in:

function refreshGrid(entity) {
  var store = window.localStorage;
  var partitionKey;
  if (exit) {
    return;
  }

Basically if you follow the issues in this link for 0.2 you'll likely get yourself fixed, I had the same problems with 0.2

val means immutable and var means mutable.

Full discussion.

Slight correction to dabest1's answer above. Specify the timezone as UTC, not GMT:

$ date -d '1970-01-01 1416275583 sec GMT'
Tue Nov 18 00:53:03 GMT 2014
$ date -d '1970-01-01 1416275583 sec UTC'
Tue Nov 18 01:53:03 GMT 2014

The second one is correct. I think the reason is that in the UK, daylight saving was in force continually from 1968 to 1971.

To supplement, here is an example expanded from the documentation, which nicely wraps all you need to know about accessing the paths/URLs in all cases with express:

app.use('/admin', function (req, res, next) { // GET 'http://www.example.com/admin/new?a=b'
  console.dir(req.originalUrl) // '/admin/new?a=b' (WARNING: beware query string)
  console.dir(req.baseUrl) // '/admin'
  console.dir(req.path) // '/new'
  console.dir(req.baseUrl + req.path) // '/admin/new' (full path without query string)
  next()
})

Based on: https://expressjs.com/en/api.html#req.originalUrl

Conclusion: As c1moore's answer states, use:

var fullPath = req.baseUrl + req.path;

I just solved it. You need to install Entity Framework again in your solution. Follow any of the approaches.

First = Right Click your Solution or Project root and click Manage NuGet Packages. Select 'EntityFramework', select the appropriate Projects and click Ok.

or

Second = Go to Console Package Manager and run Install-Package EntityFramework.

Hope it helps.

On the command prompt, do:

netstat -nb

I would actually write my own little function that does the trick by using plain old char access:

public static String trimBackslash( String str )
{
    int len, left, right;
    return str == null || ( len = str.length() ) == 0 
                           || ( ( left = str.charAt( 0 ) == '\\' ? 1 : 0 ) |
           ( right = len > left && str.charAt( len - 1 ) == '\\' ? 1 : 0 ) ) == 0
        ? str : str.substring( left, len - right );
}

This behaves similar to what String.trim() does, only that it works with '\' instead of space.

Here is one alternative that works and actually uses trim(). ;) Althogh it's not very efficient it will probably beat all regexp based approaches performance wise.

String j = “\joe\jill\”;
j = j.replace( '\\', '\f' ).trim().replace( '\f', '\\' );

The problem with detecting stackoverflows is sometimes the stack trace will unwind and you won't be able to see what's actually going on.

I've found some of Chrome's newer debugging tools useful for this.

Hit the Performance tab, make sure Javascript samples are enabled and you'll get something like this.

It's pretty obvious where the overflow is here! If you click on extendObject you'll be able to actually see the exact line number in the code.

You can also see timings which may or may not be helpful or a red herring.

Another useful trick if you can't actually find the problem is to put lots of console.log statements where you think the problem is. The previous step above can help you with this.

In Chrome if you repeatedly output identical data it will display it like this showing where the problem is more clearly. In this instance the stack hit 7152 frames before it finally crashed:

In command window type

php --ini

It will show you the path something like

Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File:         /usr/local/lib/php.ini

If the above command does not work then use this

echo phpinfo();

import binascii

binary_string = binascii.unhexlify(hex_string)

Read

binascii.unhexlify

Return the binary data represented by the hexadecimal string specified as the parameter.

The short answer is: most of the time time.clock() will be better. However, if you're timing some hardware (for example some algorithm you put in the GPU), then time.clock() will get rid of this time and time.time() is the only solution left.

Note: whatever the method used, the timing will depend on factors you cannot control (when will the process switch, how often, ...), this is worse with time.time() but exists also with time.clock(), so you should never run one timing test only, but always run a series of test and look at mean/variance of the times.

Use calc. It's the easiest I found example:

calc 1+1

 2

calc 1/10

 0.1

You should verify that new File(".") is really pointing to where you think it is pointing - .classpath suggests the root of some Eclipse project....

Use org.springframework.web.context.request.WebRequest as a parameter in your controller method, it provides the method getParameterMap(), the advantage is that you do not tight your application to the Servlet API, the WebRequest is a example of JavaEE pattern Context Object.

the data object is a buffer of bytes. Simply call .toString() to get human-readable code:

console.log( data.toString() );

reference: Node.js buffers

<input type="text" placeholder="specify">

This adds "specify" as tool-tip text inside the input box.

Instead of doing all these, one can simply use ".Result" to get the result from a particular task.

eg: List list = GetListAsync().Result;

Which as per the definition => Gets the result value of this Task < TResult >

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

when all else fails I just

<center> content </center>

I know its not "up to standards" any more, but if it works it works

After a Windows 10 update my VirtualBox Host-Only Ethernet Adapter was actually gone from the OS' network adapters (view these under Control Panel -> Network and Sharing Center -> Change adapter settings). Had to reinstall VirtualBox to bring that back to the OS.

Then in the newer version of VirtualBox, the host-only adapters are under Global Tools (top right) -> Host Network Manager. Make sure the DHCP Server is enabled for the adapter.

Example config:

It should be a Python expression that, when eval'd, creates an object with the exact same properties as this one. For example, if you have a Fraction class that contains two integers, a numerator and denominator, your __repr__() method would look like this:

# in the definition of Fraction class
def __repr__(self):
    return "Fraction(%d, %d)" % (self.numerator, self.denominator)

Assuming that the constructor takes those two values.

In Rails you can use:

{'g'=> 'a', 2 => {'v' => 'b', 'x' => { 'z' => 'c'}}}.deep_symbolize_keys!

Converts to:

{:g=>"a", 2=>{:v=>"b", :x=>{:z=>"c"}}}

This should do it:

1. Ctrl+A - select all.
2. Ctrl+Shift+L - split selection into lines.
3. Then move all cursors with left/right, select with Shift+left/right. Move all cursors to start of line with Home.

As you have found out there is no such thing as a single "local IP address". Here's how to find out the local address that can be sent out to a specific host.

1. Create a UDP socket
2. Connect the socket to an outside address (the host that will eventually receive the local address)
3. Use getsockname to get the local address

Something missing from the rest of the answers here: the len function checks that the __len__ method returns a non-negative int. The fact that len is a function means that classes cannot override this behaviour to avoid the check. As such, len(obj) gives a level of safety that obj.len() cannot.

Example:

>>> class A:
...     def __len__(self):
...         return 'foo'
...
>>> len(A())
Traceback (most recent call last):
  File "<pyshell#8>", line 1, in <module>
    len(A())
TypeError: 'str' object cannot be interpreted as an integer
>>> class B:
...     def __len__(self):
...         return -1
... 
>>> len(B())
Traceback (most recent call last):
  File "<pyshell#13>", line 1, in <module>
    len(B())
ValueError: __len__() should return >= 0

Of course, it is possible to "override" the len function by reassigning it as a global variable, but code which does this is much more obviously suspicious than code which overrides a method in a class.

I'm not familiar with napping, but using Golang's net/http package works fine (playground):

func main() {
    url := "http://restapi3.apiary.io/notes"
    fmt.Println("URL:>", url)

    var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`)
    req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
    req.Header.Set("X-Custom-Header", "myvalue")
    req.Header.Set("Content-Type", "application/json")

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    fmt.Println("response Status:", resp.Status)
    fmt.Println("response Headers:", resp.Header)
    body, _ := ioutil.ReadAll(resp.Body)
    fmt.Println("response Body:", string(body))
}

Your code is fine. In case you're not sure how to use Calculate function, try

Calculate(5,5,(Operator)0); //this will add 5,5
Calculate(5,5,Operator.PLUS);// alternate

Default enum values start from 0 and increase by one for following elements, until you assign different values. Also you can do :

public enum Operator{PLUS=21,MINUS=345,MULTIPLY=98,DIVIDE=100};

Head, or before closure of body tag. When DOM loads JS is then executed, that is exactly what jQuery document.ready does.

Adding library in Android studio 2.1

Just Go to project -> then it has some android,package ,test ,project view

Just change it to Project View

under the app->lib folder you can directly copy paste the lib and do android synchronize it. That's it

Here's an example where all the logic for waiting until the variable is set gets deferred to a function which then invokes a callback that does everything else the program needs to do - if you need to load variables before doing anything else, this feels like a neat-ish way to do it, so you're separating the variable loading from everything else, while still ensuring 'everything else' is essentially a callback.

var loadUser = function(everythingElse){
    var interval = setInterval(function(){
      if(typeof CurrentUser.name !== 'undefined'){
        $scope.username = CurrentUser.name;
        clearInterval(interval);
        everythingElse();
      }
    },1);
  };

  loadUser(function(){

    //everything else

  });

simple solution will be change spring.datasource.url=jdbc:h2:file:~/dasboot in application.properties to new file name like : spring.datasource.url=jdbc:h2:file:~/dasboots

I found a little utility function a while back and I've been using it for resetting my form elements ever since (source: http://www.learningjquery.com/2007/08/clearing-form-data):

function clearForm(form) {
  // iterate over all of the inputs for the given form element
  $(':input', form).each(function() {
    var type = this.type;
    var tag = this.tagName.toLowerCase(); // normalize case
    // it's ok to reset the value attr of text inputs, 
    // password inputs, and textareas
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = "";
    // checkboxes and radios need to have their checked state cleared 
    // but should *not* have their 'value' changed
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    // select elements need to have their 'selectedIndex' property set to -1
    // (this works for both single and multiple select elements)
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

... or as a jQuery plugin...

$.fn.clearForm = function() {
  return this.each(function() {
    var type = this.type, tag = this.tagName.toLowerCase();
    if (tag == 'form')
      return $(':input',this).clearForm();
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = '';
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

Easiest way: $injector = angular.element(document.body).injector()

Then use that to run invoke() or get()

I had the same issue and tried various things to fix this, amending the .bash_profile file, logging in and out, without any luck. In the end, restarting my machine fixed it.

if you have multiple sets of numbers then this is another option

>>> import re
>>> print(re.findall('\d+', 'xyz123abc456def789'))
['123', '456', '789']

its no good for floating point number strings though.

Use white-space: nowrap;^{[1] [2]} or give that link more space by setting li's width to greater values.

In summary of the previous comments:

function() {
  alert("hello");
}();

when not assigned to a variable, yields a syntax error. The code is parsed as a function statement (or definition), which renders the closing parentheses syntactically incorrect. Adding parentheses around the function portion tells the interpreter (and programmer) that this is a function expression (or invocation), as in

(function() {
  alert("hello");
})();

This is a self-invoking function, meaning it is created anonymously and runs immediately because the invocation happens in the same line where it is declared. This self-invoking function is indicated with the familiar syntax to call a no-argument function, plus added parentheses around the name of the function: (myFunction)();.

There is a good SO discussion JavaScript function syntax.

I have two solutions for this Question.

1. The first solution is on getting display names from enum.

public enum CourseLocationTypes
{
    [Display(Name = "On Campus")]
    OnCampus,
    [Display(Name = "Online")]
    Online,
    [Display(Name = "Both")]
    Both
}

public static string DisplayName(this Enum value)
{
    Type enumType = value.GetType();
    string enumValue = Enum.GetName(enumType, value);
    MemberInfo member = enumType.GetMember(enumValue)[0];

    object[] attrs = member.GetCustomAttributes(typeof(DisplayAttribute), false);
    string outString = ((DisplayAttribute)attrs[0]).Name;

    if (((DisplayAttribute)attrs[0]).ResourceType != null)
    {
        outString = ((DisplayAttribute)attrs[0]).GetName();
    }

    return outString;
}

<h3 class="product-title white">@Model.CourseLocationType.DisplayName()</h3>

2. The second Solution is on getting display name from enum name but that will be enum split in developer language it's called patch.

public static string SplitOnCapitals(this string text)
{
        var r = new Regex(@"
            (?<=[A-Z])(?=[A-Z][a-z]) |
             (?<=[^A-Z])(?=[A-Z]) |
             (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);

        return r.Replace(text, " ");
}

 <div class="widget-box pt-0">
     @foreach (var item in Enum.GetNames(typeof(CourseLocationType)))
     {
         <label class="pr-2 pt-1">
             @Html.RadioButtonFor(x => x.CourseLocationType, item, new { type = "radio", @class = "iCheckBox control-label" })&nbsp; @item.SplitOnCapitals()
         </label>
     }
     @Html.ValidationMessageFor(x => x.CourseLocationType)
 </div>

This line in your app.php, 'key' => env('APP_KEY', 'SomeRandomString'),, is saying that the key for your application can be found in your .env file on the line APP_KEY.

Basically it tells Laravel to look for the key in the .env file first and if there isn't one there then to use 'SomeRandomString'.

When you use the php artisan key:generate it will generate the new key to your .env file and not the app.php file.

As kotapeter said, your .env will be inside your root Laravel directory and may be hidden; xampp/htdocs/laravel/blog

It is good idea to use remote config for app version and always check in launch activity is current app version is same as remote version or not if not force for update from app store..

Simple logic happy coding..

https://firebase.google.com/docs/remote-config/android

I encountered the same problem and checked for null but it did not help. Because the script was loading before page load. So just by placing the script before the end body tag solved the problem.

I write these 2 functions to make my life easier:

function scrollToTop(elem, parent, speed) {
    var scrollOffset = parent.scrollTop() + elem.offset().top;
    parent.animate({scrollTop:scrollOffset}, speed);
    // parent.scrollTop(scrollOffset, speed);
}

function scrollToCenter(elem, parent, speed) {
    var elOffset = elem.offset().top;
    var elHeight = elem.height();
    var parentViewTop = parent.offset().top;
    var parentHeight = parent.innerHeight();
    var offset;

    if (elHeight >= parentHeight) {
        offset = elOffset;
    } else {
        margin = (parentHeight - elHeight)/2;
        offset = elOffset - margin;
    }

    var scrollOffset = parent.scrollTop() + offset - parentViewTop;

    parent.animate({scrollTop:scrollOffset}, speed);
    // parent.scrollTop(scrollOffset, speed);
}

And use them:

scrollToTop($innerListItem, $parentDiv, 200);
// or
scrollToCenter($innerListItem, $parentDiv, 200);

Here is what the MySQL docs say about NOW():

Returns the current date and time as a value in YYYY-MM-DD HH:MM:SS or YYYYMMDDHHMMSS.uuuuuu format, depending on whether the function is used in a string or numeric context. The value is expressed in the current time zone.

mysql> SELECT NOW();
        -> '2007-12-15 23:50:26'
mysql> SELECT NOW() + 0;
        -> 20071215235026.000000

Now, you can certainly reduce your smart date to something less...

SELECT (
 date_part('year', NOW())::text
 || date_part('month', NOW())::text
 || date_part('day', NOW())::text
 || date_part('hour', NOW())::text
 || date_part('minute', NOW())::text
 || date_part('second', NOW())::text
)::float8 + foo;

But, that would be a really bad idea, what you need to understand is that times and dates are not stupid unformated numbers, they are their own type with their own set of functions and operators

So the MySQL time essentially lets you treat NOW() as a dumber type, or it overrides + to make a presumption that I can't find in the MySQL docs. Eitherway, you probably want to look at the date and interval types in pg.

Here's my webpack 4 + font awesome 5 solution:

webpack plugin:

new CopyWebpackPlugin([
    { from: 'node_modules/font-awesome/fonts', to: 'font-awesome' }
  ]),

global css style:

@font-face {
    font-family: 'FontAwesome';
    src: url('/font-awesome/fontawesome-webfont.eot');
    src: url('/font-awesome/fontawesome-webfont.eot?#iefix') format('embedded-opentype'),
    url('/font-awesome/fontawesome-webfont.woff2') format('woff2'),
    url('/font-awesome/fontawesome-webfont.woff') format('woff'),
    url('/font-awesome/fontawesome-webfont.ttf') format('truetype'),
    url('/font-awesome/fontawesome-webfont.svgfontawesomeregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

i {
    font-family: "FontAwesome";
}

I've encountered this problem with a input[type="datetime-local"], which is similar to this problem.

And I've found a way to overcome this kind of problems.

First, you must turn on chrome's shadow-root feature by "DevTools -> Settings -> General -> Elements -> Show user agent shadow DOM"

Then you can see all shadowed DOM elements, for example, for <input type="number">, the full element with shadowed DOM is:

<input type="number">_x000D_
  <div id="text-field-container" pseudo="-webkit-textfield-decoration-container">_x000D_
    <div id="editing-view-port">_x000D_
      <div id="inner-editor"></div>_x000D_
    </div>_x000D_
    <div pseudo="-webkit-inner-spin-button" id="spin"></div>_x000D_
  </div>_x000D_
</input>

And according to these info, you can draft some CSS to hide unwanted elements, just as @Josh said.

A small but important detail for adjusting figure size on a one-off basis (as several commenters above reported "this doesn't work for me"):

You should do plt.figure(figsize=(,)) PRIOR to defining your actual plot. For example:

This should correctly size the plot according to your specified figsize:

values = [1,1,1,2,2,3]
_ = plt.figure(figsize=(10,6))
_ = plt.hist(values,bins=3)
plt.show()

Whereas this will show the plot with the default settings, seeming to "ignore" figsize:

values = [1,1,1,2,2,3]
_ = plt.hist(values,bins=3)
_ = plt.figure(figsize=(10,6))
plt.show()

In C arrays, arr[3] and 3[arr] are the same, and their equivalent pointer notations are *(arr + 3) to *(3 + arr). But on the contrary [arr]3 or [3]arr is not correct and will result into syntax error, as (arr + 3)* and (3 + arr)* are not valid expressions. The reason is dereference operator should be placed before the address yielded by the expression, not after the address.

Solutions listed did not exactly work for me. The closest was Chief Wiggum - I wanted to add a comment on his answer but lack the reputation to do so. So I post as separate answer:

=MIN(IF(A1:E1>0;A1:E1))

Then instead of pressing ENTER, press CTRL+SHIFT+ENTER and watch Excel add { and } to respectively the beginning and the end of the formula (to activate the formula on array).

The comma "," and "If" statement as proposed by Chief Wiggum did not work on Excel Home and Student 2013. Need a semicolon ";" as well as full cap "IF" did the trick. Small syntax difference but took me 1.5 hour to figure out why I was getting an error and #VALUE.

To use Redux-saga is the best middleware in React-redux implementation.

Ex: store.js

  import createSagaMiddleware from 'redux-saga';
  import { createStore, applyMiddleware } from 'redux';
  import allReducer from '../reducer/allReducer';
  import rootSaga from '../saga';

  const sagaMiddleware = createSagaMiddleware();
  const store = createStore(
     allReducer,
     applyMiddleware(sagaMiddleware)
   )

   sagaMiddleware.run(rootSaga);

 export default store;

And then saga.js

import {takeLatest,delay} from 'redux-saga';
import {call, put, take, select} from 'redux-saga/effects';
import { push } from 'react-router-redux';
import data from './data.json';

export function* updateLesson(){
   try{
       yield put({type:'INITIAL_DATA',payload:data}) // initial data from json
       yield* takeLatest('UPDATE_DETAIL',updateDetail) // listen to your action.js 
   }
   catch(e){
      console.log("error",e)
     }
  }

export function* updateDetail(action) {
  try{
       //To write store update details
   }  
    catch(e){
       console.log("error",e)
    } 
 }

export default function* rootSaga(){
    yield [
        updateLesson()
       ]
    }

And then action.js

 export default function updateFruit(props,fruit) {
    return (
       {
         type:"UPDATE_DETAIL",
         payload:fruit,
         props:props
       }
     )
  }

And then reducer.js

import {combineReducers} from 'redux';

const fetchInitialData = (state=[],action) => {
    switch(action.type){
      case "INITIAL_DATA":
          return ({type:action.type, payload:action.payload});
          break;
      }
     return state;
  }
 const updateDetailsData = (state=[],action) => {
    switch(action.type){
      case "INITIAL_DATA":
          return ({type:action.type, payload:action.payload});
          break;
      }
     return state;
  }
const allReducers =combineReducers({
   data:fetchInitialData,
   updateDetailsData
 })
export default allReducers; 

And then main.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './app/components/App.jsx';
import {Provider} from 'react-redux';
import store from './app/store';
import createRoutes from './app/routes';

const initialState = {};
const store = configureStore(initialState, browserHistory);

ReactDOM.render(
       <Provider store={store}>
          <App />  /*is your Component*/
       </Provider>, 
document.getElementById('app'));

try this.. is working

Handy with error_log() if you're outputting multiple lines.

I've found a lot of debug statements look weird on my windows install since the developers have assumed unix endings when breaking up strings.

Create Relative layout and inside that layout create your button with this line

android:layout_alignParentBottom="true"

Heres a another take on this problem, using recursion and without using mutable variables. Also, im not using setInterval so theres no cleanup that has to be done.

Having this HTML

<section id="testimonials">
    <h2>My testimonial spinner</h2>
    <div class="testimonial">
      <p>First content</p>
    </div>
    <div class="testimonial">
      <p>Second content</p>
    </div>
    <div class="testimonial">
       <p>Third content</p>
    </div>
</section>

Using ES2016

Here you call the function recursively and update the arguments.

  const testimonials = $('#testimonials')
      .children()
      .filter('div.testimonial');

  const showTestimonial = index => {

    testimonials.hide();
    $(testimonials[index]).fadeIn();

    return index === testimonials.length
      ? showTestimonial(0)
      : setTimeout(() => { showTestimonial(index + 1); }, 10000);
   }

showTestimonial(0); // id of the first element you want to show.

You can use System.IO.Path.GetFileName to do this.

E.g.,

string[] files = Directory.GetFiles(dir);
foreach(string file in files)
    Console.WriteLine(Path.GetFileName(file));

While you could use FileInfo, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFiles unless you need the additional functionality of the FileInfo class.

Active mode: -server initiates the connection.

Passive mode: -client initiates the connection.

_{Old question but adding answer so that one can get help}

Its two step process:

Suppose, a table1 has a foreign key with column name fk_table2_id, with constraint name fk_name and table2 is referred table with key t2 (something like below in my diagram).

   table1 [ fk_table2_id ] --> table2 [t2]

First step, DROP old CONSTRAINT: (reference)

ALTER TABLE `table1` 
DROP FOREIGN KEY `fk_name`;  

_{notice constraint is deleted, column is not deleted}

Second step, ADD new CONSTRAINT:

ALTER TABLE `table1`  
ADD CONSTRAINT `fk_name` 
    FOREIGN KEY (`fk_table2_id`) REFERENCES `table2` (`t2`) ON DELETE CASCADE;  

_{adding constraint, column is already there}

Example:

I have a UserDetails table refers to Users table:

mysql> SHOW CREATE TABLE UserDetails;
:
:
 `User_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`Detail_id`),
  KEY `FK_User_id` (`User_id`),
  CONSTRAINT `FK_User_id` FOREIGN KEY (`User_id`) REFERENCES `Users` (`User_id`)
:
:

First step:

mysql> ALTER TABLE `UserDetails` DROP FOREIGN KEY `FK_User_id`;
Query OK, 1 row affected (0.07 sec)  

Second step:

mysql> ALTER TABLE `UserDetails` ADD CONSTRAINT `FK_User_id` 
    -> FOREIGN KEY (`User_id`) REFERENCES `Users` (`User_id`) ON DELETE CASCADE;
Query OK, 1 row affected (0.02 sec)  

result:

mysql> SHOW CREATE TABLE UserDetails;
:
:
`User_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`Detail_id`),
  KEY `FK_User_id` (`User_id`),
  CONSTRAINT `FK_User_id` FOREIGN KEY (`User_id`) REFERENCES 
                                       `Users` (`User_id`) ON DELETE CASCADE
:

SSL development libraries have to be installed

CentOS:

$ yum install openssl-devel libffi-devel

Ubuntu:

$ apt-get install libssl-dev libffi-dev

OS X (with Homebrew installed):

$ brew install openssl

The data is UTF-8 encoded bytes escaped with URL quoting, so you want to decode, with urllib.parse.unquote(), which handles decoding from percent-encoded data to UTF-8 bytes and then to text, transparently:

from urllib.parse import unquote

url = unquote(url)

Demo:

>>> from urllib.parse import unquote
>>> url = 'example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0'
>>> unquote(url)
'example.com?title=????????+??????'

The Python 2 equivalent is urllib.unquote(), but this returns a bytestring, so you'd have to decode manually:

from urllib import unquote

url = unquote(url).decode('utf8')

As per this example:

import numpy as np
import matplotlib.pyplot as plt

N = 50
x = np.random.rand(N)
y = np.random.rand(N)

plt.scatter(x, y)
plt.show()

will produce:

To unpack your data from pairs into lists use zip:

x, y = zip(*li)

So, the one-liner:

plt.scatter(*zip(*li))

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

If you want the GUI to behave as if you clicked the X close button then you need to dispatch a window closing event to the Window. The ExitAction from Closing An Application allows you to add this functionality to a menu item or any component that uses Actions easily.

frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));

After reading all the answers and comments on this question, I thought to do a small experiment.

I generated 50,000 random booleans and called sum and count on them.

Here are my results:

>>> a = [bool(random.getrandbits(1)) for x in range(50000)]
>>> len(a)
50000
>>> a.count(False)
24884
>>> a.count(True)
25116
>>> def count_it(a):
...   curr = time.time()
...   counting = a.count(True)
...   print("Count it = " + str(time.time() - curr))
...   return counting
... 
>>> def sum_it(a):
...   curr = time.time()
...   counting = sum(a)
...   print("Sum it = " + str(time.time() - curr))
...   return counting
... 
>>> count_it(a)
Count it = 0.00121307373046875
25015
>>> sum_it(a)
Sum it = 0.004102230072021484
25015

Just to be sure, I repeated it several more times:

>>> count_it(a)
Count it = 0.0013530254364013672
25015
>>> count_it(a)
Count it = 0.0014507770538330078
25015
>>> count_it(a)
Count it = 0.0013344287872314453
25015
>>> sum_it(a)
Sum it = 0.003480195999145508
25015
>>> sum_it(a)
Sum it = 0.0035257339477539062
25015
>>> sum_it(a)
Sum it = 0.003350496292114258
25015
>>> sum_it(a)
Sum it = 0.003744363784790039
25015

And as you can see, count is 3 times faster than sum. So I would suggest to use count as I did in count_it.

On OS X, use pbcopy; pbpaste goes in the opposite direction.

You'll probably have to put another element around the table and style that with a rounded border.

The working draft specifies that border-radius does not apply to table elements when the value of border-collapse is collapse.

You won't need a library; if you are using a recent version of Java, have a look at String.format:

String.format("Hello %s!", "world");

Editor editor = getSharedPreferences("clear_cache", Context.MODE_PRIVATE).edit();
editor.clear();
editor.commit();

You can pass values from one activity to another activity using the Bundle. In your current activity, create a bundle and set the bundle for the particular value and pass that bundle to the intent.

Intent intent = new Intent(this,NewActivity.class);
Bundle bundle = new Bundle();
bundle.putString(key,value);
intent.putExtras(bundle);
startActivity(intent);

Now in your NewActivity, you can get this bundle and retrive your value.

Bundle bundle = getArguments();
String value = bundle.getString(key);

You can also pass data through the intent. In your current activity, set intent like this,

Intent intent = new Intent(this,NewActivity.class);
intent.putExtra(key,value);
startActivity(intent);

Now in your NewActivity, you can get that value from intent like this,

String value = getIntent().getExtras().getString(key);

If you want to remove spaces at the beginning/end of a line too(common when shortening html) you can try:

string.Join("",input.Split('\n','\r').Select(s=>s.Trim()))

Else use the simple Replace Marc suggested.

Add your library folder in your root location of your project and copy all the library files there. For ex YourProject/library then sync it and rest things seems OK to me.

Some explanation about this regular expression might be useful: ^(.+?)\n\n((?:[A-Z]+\n)+)

• The first character (^) means "starting at the beginning of a line". Be aware that it does not match the newline itself (same for $: it means "just before a newline", but it does not match the newline itself).
• Then (.+?)\n\n means "match as few characters as possible (all characters are allowed) until you reach two newlines". The result (without the newlines) is put in the first group.
• [A-Z]+\n means "match as many upper case letters as possible until you reach a newline. This defines what I will call a textline.
• ((?:textline)+) means match one or more textlines but do not put each line in a group. Instead, put all the textlines in one group.
• You could add a final \n in the regular expression if you want to enforce a double newline at the end.
• Also, if you are not sure about what type of newline you will get (\n or \r or \r\n) then just fix the regular expression by replacing every occurrence of \n by (?:\n|\r\n?).

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Fortunately, it's not possible (for security reasons) to access client-side filesystem with standard JS. Some proprietary solutions exist though (like Microsoft's IE-only ActiveX component).

A Function To Do This

extract () {
  if [ -f $1 ] ; then
      case $1 in
          *.tar.bz2)   tar xvjf $1    ;;
          *.tar.gz)    tar xvzf $1    ;;
          *.bz2)       bunzip2 $1     ;;
          *.rar)       rar x $1       ;;
          *.gz)        gunzip $1      ;;
          *.tar)       tar xvf $1     ;;
          *.tbz2)      tar xvjf $1    ;;
          *.tgz)       tar xvzf $1    ;;
          *.zip)       unzip $1       ;;
          *.Z)         uncompress $1  ;;
          *.7z)        7z x $1        ;;
          *)           echo "don't know '$1'..." ;;
      esac
  else
      echo "'$1' is not a valid file!"
  fi
}

Other Note

In response to Aquarius Power in the comment above, We need to store the regex on a var

The variable BASH_REMATCH is set after you match the expression, and ${BASH_REMATCH[n]} will match the nth group wrapped in parentheses ie in the following ${BASH_REMATCH[1]} = "compressed" and ${BASH_REMATCH[2]} = ".gz"

if [[ "compressed.gz" =~ ^(.*)(\.[a-z]{1,5})$ ]]; 
then 
  echo ${BASH_REMATCH[2]} ; 
else 
  echo "Not proper format"; 
fi

(The regex above isn't meant to be a valid one for file naming and extensions, but it works for the example)

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

Here is an example of a simple Two-column class:

.two-col {
       -moz-column-count: 2;
       -moz-column-gap: 20px;
       -webkit-column-count: 2;
       -webkit-column-gap: 20px;
}

Of which you would apply to a block of text like so:

<p class="two-col">Text</p>

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

I've not met that particular package before, but it says it's for client-side HTTP authentication, which I've been able to do on Android using the java.net APIs, like so:

Authenticator.setDefault(new Authenticator(){
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("myuser","mypass".toCharArray());
    }});
HttpURLConnection c = (HttpURLConnection) new URL(url).openConnection();
c.setUseCaches(false);
c.connect();

Obviously your getPasswordAuthentication() should probably do something more intelligent than returning a constant.

If you're trying to make a request with a body (e.g. POST) with authentication, beware of Android issue 4326. I've linked a suggested fix to the platform there, but there's a simple workaround if you only want Basic auth: don't bother with Authenticator, and instead do this:

c.setRequestProperty("Authorization", "basic " +
        Base64.encode("myuser:mypass".getBytes(), Base64.NO_WRAP));

I think that I remember looking at a performance comparison between int.TryParse and int.Parse Regex and char.IsNumber and char.IsNumber was fastest. At any rate, whatever the performance, here's one more way to do it.

        bool isNumeric = true;
        foreach (char c in "12345")
        {
            if (!Char.IsNumber(c))
            {
                isNumeric = false;
                break;
            }
        }

I have never been a fan of closing blocks of PHP to output content to the browser, I prefer to have my output captured so if at some point within my logic I decide I want to change my output (after output has already been sent) I can just delete the current buffer.

But as Pekka said, the main reason you are having issues with your javascript inclusion is because your using href to specify the location of the js file where as you should be using src.

If you have a functions file with your functions inside then add something like:

function js_link($src)
{
    if(file_exists("my/html/root/" . $src))
    {
        //we know it will exists within the HTTP Context
        return sprintf("<script type=\"text/javascript\" src=\"%s\"></script>",$src);
    }
    return "<!-- Unable to load " . $src . "-->";
}

The n in your code without the need for closing your blocks with ?> you can just use:

echo js_link("jquery/1.6/main.js");

It's all about the selector. You can change your code to be something like this:

<div class="formbuilder">
    <div class="active">Heading</div>
    <div>1</div>
    <div>2</div>
    <div>3</div>
    <div>4</div>
</div>

Then use this javascript:

$(document).ready(function () {
    $('.formbuilder div').on('click', function () {
        $('.formbuilder div').removeClass('active');
        $(this).addClass('active');
    });
});

The example in a working jsfiddle

See this api about the selector I used: http://api.jquery.com/descendant-selector/

The best to remove a class in jquery from all the elements is to target via element tag. e.g.,

$("div").removeClass("highlight");

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

Here is a working example. I changed the code to output to a div instead of an alert box. Your issue was item.innerHTML I believe. I use the jQuery html function instead and that seemed to resolve the issue.

<table id='thisTable' class='disptable' style='margin-left:auto;margin-right:auto;'  >
    <tr>

   <th>Fund</th>
   <th>Organization</th>
   <th>Access</th>
   <th>Delete</th>
   </tr>
    <tr>
   <td class='fund'>100000</td><td class='org'>10110</td><td>OWNED</td><td><a  class='delbtn'ref='#'>X</a></td></tr>
   <tr><td class='fund'>100000</td><td class='org'>67130</td><td>OWNED</td><td><a class='delbtn' href='#'>X</a></td></tr>
   <tr><td class='fund'>170252</td><td class='org'>67130</td><td>OWNED</td><td><a class='delbtn' href='#'>X</a></td></tr>
   <tr><td class='fund'>100000</td><td class='org'>67150</td><td>PENDING ACCESS</td><td><a  class='delbtn' href='#'>X</a></td></tr>
   <tr><td class='fund'>100000</td><td class='org'>67120</td><td>PENDING ACCESS</td><td><a class='delbtn' href='#'>X</a>
   </td>
  </tr>
</table>
<div id="output"></div>?

the javascript:

$('#thisTable tr').on('click', function(event) {    
    var tds = $(this).addClass('row-highlight').find('td');
    var values = '';
    tds.each(function(index, item) {           
        values = values + 'td' + (index + 1) + ':' + $(item).html() + '<br/>';
    });
    $("#output").html(values);
});

Try using input arrays:

<form action="try.php" method="post">
    <div id="events_wrapper">
        <div id="sub_events">
            <input type="text" name="firstname[]" />                                       
        </div>
    </div>
    <input type="button" id="add_another_event" name="add_another_event" value="Add Another" />
    <input type="submit" name="submit" value="submit" />
</form>

and add this script and jQuery, using foreach() to retrieve the data being $_POST'ed:

<script>                                                                                    
    $(document).ready(function(){
        $("#add_another_event").click(function(){
        var $address = $('#sub_events');
        var num = $('.clonedAddress').length; // there are 5 children inside each address so the prevCloned address * 5 + original
        var newNum = num + 1;
        var newElem = $address.clone().attr('id', 'address' + newNum).addClass('clonedAddress');

        //set all div id's and the input id's
        newElem.children('div').each (function (i) {
            this.id = 'input' + (newNum*5 + i);
        });

        newElem.find('input').each (function () {
            this.id = this.id + newNum;
            this.name = this.name + newNum;
        });

        if (num > 0) {
            $('.clonedAddress:last').after(newElem);
        } else {
            $address.after(newElem);
        }

        $('#btnDel').removeAttr('disabled');
        });

        $("#remove").click(function(){

        });

    });
</script>

In Java 8, it can be done using

String[] arrayFromList = fromlist.stream().toArray(String[]::new);

Another functional approach which is maybe a little easier to look at than an anonymous function if you go that route is using functools.partial to utilize the two-parameter operator.mul with a fixed multiple

>>> from functools import partial
>>> from operator import mul
>>> double = partial(mul, 2)
>>> list(map(double, [1, 2, 3]))
[2, 4, 6]

Not sure if this is the most efficient method, but it might be relatively interesting: the the Burrows-Wheeler transform. According to the WP article, all rotations of the input yield the same output. For applications such as compression this isn't desirable, so the original rotation is indicated (e.g. by an index; see the article). But for simple rotation-independent comparison, it sounds ideal. Of course, it's not necessarily ideally efficient!

I like @huynhjl's answer, it led me down the right path. However, it isn't great at handling error conditions. If the desired node does not exist, you get a cast exception. I've adapted this slightly to make use of Option to better handle this.

class CC[T] {
  def unapply(a:Option[Any]):Option[T] = if (a.isEmpty) {
    None
  } else {
    Some(a.get.asInstanceOf[T])
  }
}

object M extends CC[Map[String, Any]]
object L extends CC[List[Any]]
object S extends CC[String]
object D extends CC[Double]
object B extends CC[Boolean]

for {
  M(map) <- List(JSON.parseFull(jsonString))
  L(languages) = map.get("languages")
  language <- languages
  M(lang) = Some(language)
  S(name) = lang.get("name")
  B(active) = lang.get("is_active")
  D(completeness) = lang.get("completeness")
} yield {
  (name, active, completeness)
}

Of course, this doesn't handle errors so much as avoid them. This will yield an empty list if any of the json nodes are missing. You can use a match to check for the presence of a node before acting...

for {
  M(map) <- Some(JSON.parseFull(jsonString))
} yield {
  map.get("languages") match {
    case L(languages) => {
      for {
        language <- languages
        M(lang) = Some(language)
        S(name) = lang.get("name")
        B(active) = lang.get("is_active")
        D(completeness) = lang.get("completeness")
      } yield {
        (name, active, completeness)
      }        
    }
    case None => "bad json"
  }
}

I've made some changes to code given by Mark Byers. Below function will also adds empty directories if you have them. Examples should make it more clear what is the path added to the zip.

#!/usr/bin/env python
import os
import zipfile

def addDirToZip(zipHandle, path, basePath=""):
    """
    Adding directory given by \a path to opened zip file \a zipHandle

    @param basePath path that will be removed from \a path when adding to archive

    Examples:
        # add whole "dir" to "test.zip" (when you open "test.zip" you will see only "dir")
        zipHandle = zipfile.ZipFile('test.zip', 'w')
        addDirToZip(zipHandle, 'dir')
        zipHandle.close()

        # add contents of "dir" to "test.zip" (when you open "test.zip" you will see only it's contents)
        zipHandle = zipfile.ZipFile('test.zip', 'w')
        addDirToZip(zipHandle, 'dir', 'dir')
        zipHandle.close()

        # add contents of "dir/subdir" to "test.zip" (when you open "test.zip" you will see only contents of "subdir")
        zipHandle = zipfile.ZipFile('test.zip', 'w')
        addDirToZip(zipHandle, 'dir/subdir', 'dir/subdir')
        zipHandle.close()

        zipHandle = zipfile.ZipFile('test.zip', 'w')
        addDirToZip(zipHandle, 'dir/subdir', 'dir')
        zipHandle.close()

        # add whole "dir/subdir" with full path to "test.zip" (when you open "test.zip" you will see only "dir" and inside it only "subdir")
        zipHandle = zipfile.ZipFile('test.zip', 'w')
        addDirToZip(zipHandle, 'dir/subdir')
        zipHandle.close()

        # add whole "dir" and "otherDir" (with full path) to "test.zip" (when you open "test.zip" you will see only "dir" and "otherDir")
        zipHandle = zipfile.ZipFile('test.zip', 'w')
        addDirToZip(zipHandle, 'dir')
        addDirToZip(zipHandle, 'otherDir')
        zipHandle.close()
    """
    basePath = basePath.rstrip("\\/") + ""
    basePath = basePath.rstrip("\\/")
    for root, dirs, files in os.walk(path):
        # add dir itself (needed for empty dirs
        zipHandle.write(os.path.join(root, "."))
        # add files
        for file in files:
            filePath = os.path.join(root, file)
            inZipPath = filePath.replace(basePath, "", 1).lstrip("\\/")
            #print filePath + " , " + inZipPath
            zipHandle.write(filePath, inZipPath)

Above is a simple function that should work for simple cases. You can find more elegant class in my Gist: https://gist.github.com/Eccenux/17526123107ca0ac28e6

There is no difference between the two, one is just a shorthand for the second.

The v- prefix serves as a visual cue for identifying Vue-specific attributes in your templates. This is useful when you are using Vue.js to apply dynamic behavior to some existing markup, but can feel verbose for some frequently used directives. At the same time, the need for the v- prefix becomes less important when you are building an SPA where Vue.js manages every template.

<!-- full syntax -->
<a v-on:click="doSomething"></a>
<!-- shorthand -->
<a @click="doSomething"></a>

The spec files are unit tests for your source files. The convention for Angular applications is to have a .spec.ts file for each .ts file. They are run using the Jasmine javascript test framework through the Karma test runner (https://karma-runner.github.io/) when you use the ng test command.

You can use this for some further reading:

Socket.io uses the EventEmitter pattern to disconnect/connect/check heartbeats so you could do. Client.emit('disconnect');

$arr = array(1, 'a', 3, 4 => 1, 'b' => 1);
foreach ($arr as $key => $val) {
    echo "{$key} = {$val}" . (end(array_keys($arr))===$key ? '' : ', ');
}
// output: 0 = 1, 1 = a, 2 = 3, 4 = 1, b = 1

Since in your situation you only want to notify the user with a short and simple message, a Toast would make for a better user experience.

Toast.makeText(getApplicationContext(), "Data saved", Toast.LENGTH_LONG).show();

Update: A Snackbar is recommended now instead of a Toast for Material Design apps.

If you have a more lengthy message that you want to give the reader time to read and understand, then you should use a DialogFragment. (The documentation currently recommends wrapping your AlertDialog in a fragment rather than calling it directly.)

Make a class that extends DialogFragment:

public class MyDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("App Title");
        builder.setMessage("This is an alert with no consequence");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // You don't have to do anything here if you just 
                // want it dismissed when clicked
            }
        });

        // Create the AlertDialog object and return it
        return builder.create();
    }
}

Then call it when you need it in your activity:

DialogFragment dialog = new MyDialogFragment();
dialog.show(getSupportFragmentManager(), "MyDialogFragmentTag");

The round funtion stated does not works for definate integers like :

a=8
round(a,3)
8.0
a=8.00
round(a,3)
8.0
a=8.000000000000000000000000
round(a,3)
8.0

but , works for :

r=400/3.0
r
133.33333333333334
round(r,3)
133.333

Morever the decimals like 2.675 are rounded as 2.67 not 2.68.
Better use the other method provided above.

I got this error using Spring Boot (in Mozilla),

because I was just testing some basic controller -> service -> repository communication by directly returning some entities from the database to the browser (as JSON).

I forgot to put data in the database, so my method wasn't returning anything... and I got this error.

Now that I put some data in my db, it works fine (the error is removed). :D

Anonymous classes always extend superclass or implements interfaces. for example:

button.addActionListener(new ActionListener(){ // ActionListener is an interface
    public void actionPerformed(ActionEvent e){
    }
});

Moreover, although anonymous class cannot implement multiple interfaces, you can create an interface that extends other interface and let your anonymous class to implement it.

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);

sync method first lists both source and destination paths and copies only differences (name, size etc.).

cp --recursive method lists source path and copies (overwrites) all to the destination path.

If you have possible matches in the destination path, I would suggest sync as one LIST request on the destination path will save you many unnecessary PUT requests - meaning cheaper and possibly faster.

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

Rule No.1: Never let the user wait for anything.

That in mind a life growing page that needs 10seconds appears way faster than waiting 3 seconds on before a blank screen and get all at once.

So instead of make the page fast, just let the page appear to be fast, even if the final result is slower:

function applyItemlist(items){
    var item = items.shift();
    if(item){
        $timeout(function(){
            $scope.items.push(item);
            applyItemlist(items);
        }, 0); // <-- try a little gap of 10ms
    }
}

The code above let appear the list to be growing row-by-row, and is always slower than render all at once. But for the user it appears to be faster.

This is my working version. Note that the resolvers code is not shown but are a spin on my implementation which allows columns to be resolved even though they are named slightly differently in each worksheet.

public static IEnumerable<T> ToArray<T>(this ExcelWorksheet worksheet, List<PropertyNameResolver> resolvers) where T : new()
{

  // List of all the column names
  var header = worksheet.Cells.GroupBy(cell => cell.Start.Row).First();

  // Get the properties from the type your are populating
  var properties = typeof(T).GetProperties().ToList();


  var start = worksheet.Dimension.Start;
  var end = worksheet.Dimension.End;

  // Resulting list
  var list = new List<T>();

  // Iterate the rows starting at row 2 (ie start.Row + 1)
  for (int row = start.Row + 1; row <= end.Row; row++)
  {
    var instance = new T();
    for (int col = start.Column; col <= end.Column; col++)
    {
      object value = worksheet.Cells[row, col].Text;

      // Get the column name zero based (ie col -1)
      var column = (string)header.Skip(col - 1).First().Value;

      // Gets the corresponding property to set
      var property = properties.Property(resolvers, column);

      try
      {
        var propertyName = property.PropertyType.IsGenericType
          ? property.PropertyType.GetGenericArguments().First().FullName
          : property.PropertyType.FullName;


        // Implement setter code as needed. 
        switch (propertyName)
        {
          case "System.String":
            property.SetValue(instance, Convert.ToString(value));
            break;
          case "System.Int32":
            property.SetValue(instance, Convert.ToInt32(value));
            break;
          case "System.DateTime":
            if (DateTime.TryParse((string) value, out var date))
            {
              property.SetValue(instance, date);
            }
            property.SetValue(instance, FromExcelSerialDate(Convert.ToInt32(value)));
            break;
          case "System.Boolean":
            property.SetValue(instance, (int)value == 1);
            break;
        }
      }
      catch (Exception e)
      {
        // instance property is empty because there was a problem.
      }

    } 
    list.Add(instance);
  }
  return list;
}

// Utility function taken from the above post's inline function.
public static DateTime FromExcelSerialDate(int excelDate)
{
  if (excelDate < 1)
    throw new ArgumentException("Excel dates cannot be smaller than 0.");

  var dateOfReference = new DateTime(1900, 1, 1);

  if (excelDate > 60d)
    excelDate = excelDate - 2;
  else
    excelDate = excelDate - 1;
  return dateOfReference.AddDays(excelDate);
}

The CSS below stops users from being able to select text.

-webkit-user-select: none; /* Safari */        
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* IE10+/Edge */
user-select: none; /* Standard */

To target IE9 downwards the html attribute unselectable must be used instead:

<p unselectable="on">Test Text</p>

This snippet is from working code.

You can trigger bat file not only from Windows GUI or Task Scheduler, but directly from PHP script when you need it. But in most cases it will have execution for 30-60 sec. depending from your PHP configuration. If job in BAT file is long and you don't want to freeze your PHP scripts, you need to fork BAT job as another process using php.exe and not be dependable from Apache.

This runs in background mode in Windows, seen as separate processes cmd.exe and php.exe from Task Manager not halting your Apache PHP scripts. The messages produced by your script may be stored and retrieved back via log files.

In my case in file_scanner.php I do some heavy calculations in loop for big array of files which may last for few hours with php function sleep() not to overload CPU.

The success poiner result from file $r which you can query via ajax if you want to know success or fauty start. In my case file_scanner.php writes log file with messages somefile.jpg - OK wich you can load to your UI with AJAX every few seconds to show progress.

PHP

/**
 * Runs bat file in background mode
 *
 */
 function run_scanner() {

    $c='start /b D:\Web\example.com\tasks\file_scanner.bat'; 
    $r=pclose(popen($c, 'r')); 
    return json_encode(array('result'=>$r));

 }

BAT

@echo Off
D:\PHP\php.exe D:\Web\example.com\tasks\file_scanner.php > D:\Web\example.com\tasks\file_scanner.log
exit

You should set your domain for example: www.abi.wapka.mobi, that is if you are using a wapka site.

Note that if you had a domain with wapka it won't work, so compare wapka with your site provider and text it.

Following code worked for me:

     git fetch
     git checkout <branch from which file needs to be fetched> <filepath> 

Try below code

I will recommend to use error handler while using vlookup because error might occur when the lookup_value is not found.

Private Sub ComboBox1_Change()


    On Error Resume Next
    Ret = Application.WorksheetFunction.VLookup(Me.ComboBox1.Value, Worksheets("Sheet3").Range("Names"), 2, False)
    On Error GoTo 0

    If Ret <> "" Then MsgBox Ret


End Sub

OR

 On Error Resume Next

    Result = Application.VLookup(Me.ComboBox1.Value, Worksheets("Sheet3").Range("Names"), 2, False)

    If Result = "Error 2042" Then
        'nothing found
    ElseIf cell <> Result Then
        MsgBox cell.Value
    End If

    On Error GoTo 0

def some_view(request):
    if request.method == 'POST':
        form = SomeForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks'/)
    else:
        form = SomeForm()
    return render(request, 'some_form.html', {'form': form})

Selected answer throws exceptions, and the answer from Carlos Toledo applies filtering after retrieving all values from the database.

The following one runs a single round-trip and reads a single value, using any possible indexes, without an exception.

int maxAge = _dbContext.Persons
  .OrderByDescending(p => p.Age)
  .Select(p => p.Age)
  .FirstOrDefault();

You forgot braces around the if block, and a semicolon between the statements in the block.

awk '{if($3 != 0) {a = ($3/$4); print $0, a;} else if($3==0) print $0, "-" }' file > out

1) What is Express.js?

Express.js is a Node.js framework. It's the most popular framework as of now (the most starred on NPM).

.

It's built around configuration and granular simplicity of Connect middleware. Some people compare Express.js to Ruby Sinatra vs. the bulky and opinionated Ruby on Rails.

2) What is the purpose of it with Node.js?

That you don't have to repeat same code over and over again. Node.js is a low-level I/O mechanism which has an HTTP module. If you just use an HTTP module, a lot of work like parsing the payload, cookies, storing sessions (in memory or in Redis), selecting the right route pattern based on regular expressions will have to be re-implemented. With Express.js, it is just there for you to use.

3) Why do we actually need Express.js? How it is useful for us to use with Node.js?

The first answer should answer your question. If no, then try to write a small REST API server in plain Node.js (that is, using only core modules) and then in Express.js. The latter will take you 5-10x less time and lines of code.

What is Redis? Does it come with Express.js?

Redis is a fast persistent key-value storage. You can optionally use it for storing sessions with Express.js, but you don't need to. By default, Express.js has memory storage for sessions. Redis also can be use for queueing jobs, for example, email jobs.

Check out my tutorial on REST API server with Express.js.

MVC but not by itself

Express.js is not an model-view-controller framework by itself. You need to bring your own object-relational mapping libraries such as Mongoose for MongoDB, Sequelize (http://sequelizejs.com) for SQL databases, Waterline (https://github.com/balderdashy/waterline) for many databases into the stack.

Alternatives

Other Node.js frameworks to consider (https://www.quora.com/Node-js/Which-Node-js-framework-is-best-for-building-a-RESTful-API):

UPDATE: I put together this resource that aid people in choosing Node.js frameworks: http://nodeframework.com

To create a Twitter share link with a photo, you first need to tweet out the photo from your Twitter account. Once you've tweeted it out, you need to grab the pic.twitter.com link and place that inside your twitter share url.

note: You won't be able to see the pic.twitter.com url so what I do is use a separate account and hit the retweet button. A modal will pop up with the link inside.

You Twitter share link will look something like this:

<a href="https://twitter.com/home?status=This%20photo%20is%20awesome!%20Check%20it%20out:%20pic.twitter.com/9Ee63f7aVp">Share on Twitter</a>

Hopefully it will help new beginners

If you dont have keystore than use before command else skip

Generating a signing key / Keystore file You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

you will get a file like my-release-key.keystore

Setting up gradle variables Place the my-release-key.keystore file under the android/app directory in your project folder. Edit the file android/gradle.properties and add the following (replace ***** with the correct keystore password, alias and key password), enableAapt2 set false is workaround , as android gradle version 3.0 problem

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=*****
MYAPP_RELEASE_KEY_PASSWORD=*****

android.enableAapt2=false

then add these app/buid.gradle (app)

below default config

signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }

and Inside Build type release { }

 signingConfig signingConfigs.release

then simply run this command in android studio terminal Below commands will automate above all answers

if windows

cd android
gradlew assembleRelease

if linux / mac

$ cd android
$ ./gradlew assembleRelease

if you got any error delete all build folder and run command

gradlew clean

than again

gradlew assembleRelease

In C# you can do something like

 String.Format("hello {0}, your age is {1}.",  "John",  29) 

In JavaScript you could do something like

 var x = "hello {0}, your age is {1}";
 x = x.replace(/\{0\}/g, "John");
 x = x.replace(/\{1\}/g, 29);

You don't have to, but some people like to explicitly initialize all variables (I do too). Especially those who program in a variety of languages, it's just easier to have the rule of always initializing your variables rather than deciding case-by-case/language-by-language.

For instance Java has default values for Boolean, int etc .. C on the other hand doesn't automatically give initial values, whatever happens to be in memory is what you end up with unless you assign a value explicitly yourself.

In your case above, as you discovered, the code works just as well without the initialization, esp since the variable is set in the next line which makes it appear particularly redundant. Sometimes you can combine both of those lines (declaration and initialization - as shown in some of the other posts) and get the best of both approaches, i.e., initialize the your variable with the result of the email1.equals (email2); operation.

You should consider using a button for this. Links generally should be use for linking. Buttons can be used for other functionality you wish to add. Neals solution works, but its a workaround.

If you use a <button> instead of a <a>, your original code should work as expected.

I wanted to do counts and sums over full resultset. I achieved grouping by all with GROUP BY 1=1.

The IFRAME element may be a security risk if your site is embedded inside an IFRAME on hostile site. Google "clickjacking" for more details. Note that it does not matter if you use <iframe> or not. The only real protection from this attack is to add HTTP header X-Frame-Options: DENY and hope that the browser knows its job.

In addition, IFRAME element may be a security risk if any page on your site contains an XSS vulnerability which can be exploited. In that case the attacker can expand the XSS attack to any page within the same domain that can be persuaded to load within an <iframe> on the page with XSS vulnerability. This is because content from the same origin (same domain) is allowed to access the parent content DOM (practically execute JavaScript in the "host" document). The only real protection methods from this attack is to add HTTP header X-Frame-Options: DENY and/or always correctly encode all user submitted data (that is, never have an XSS vulnerability on your site - easier said than done).

That's the technical side of the issue. In addition, there's the issue of user interface. If you teach your users to trust that URL bar is supposed to not change when they click links (e.g. your site uses a big iframe with all the actual content), then the users will not notice anything in the future either in case of actual security vulnerability. For example, you could have an XSS vulnerability within your site that allows the attacker to load content from hostile source within your iframe. Nobody could tell the difference because the URL bar still looks identical to previous behavior (never changes) and the content "looks" valid even though it's from hostile domain requesting user credentials.

If somebody claims that using an <iframe> element on your site is dangerous and causes a security risk, he does not understand what <iframe> element does, or he is speaking about possibility of <iframe> related vulnerabilities in browsers. Security of <iframe src="..."> tag is equal to <img src="..." or <a href="..."> as long there are no vulnerabilities in the browser. And if there's a suitable vulnerability, it might be possible to trigger it even without using <iframe>, <img> or <a> element, so it's not worth considering for this issue.

However, be warned that content from <iframe> can initiate top level navigation by default. That is, content within the <iframe> is allowed to automatically open a link over current page location (the new location will be visible in the address bar). The only way to avoid that is to add sandbox attribute without value allow-top-navigation. For example, <iframe sandbox="allow-forms allow-scripts" ...>. Unfortunately, sandbox also disables all plugins, always. For example, Youtube content cannot be sandboxed because Flash player is still required to view all Youtube content. No browser supports using plugins and disallowing top level navigation at the same time.

Note that X-Frame-Options: DENY also protects from rendering performance side-channel attack that can read content cross-origin (also known as "Pixel perfect Timing Attacks").

Different languages do different things with different levels of efficiency.

The Benchmarks Game has a whole load of different programming problems implemented in a lot of different languages.

I don't know if I'm on the right path, but I got it working on ng 2.4.8 with the following form/submit tags:

<form #heroForm="ngForm" (ngSubmit)="add(newHero); heroForm.reset()">
<!-- place your input stuff here -->
<button type="submit" class="btn btn-default" [disabled]="!heroForm.valid">Add hero</button>

Seems to do the trick and sets the form's fields to "pristine" again.

A deadlock happens when a thread is waiting for something that never occurs.

Typically, it happens when a thread is waiting on a mutex or semaphore that was never released by the previous owner.

It also frequently happens when you have a situation involving two threads and two locks like this:

Thread 1               Thread 2

Lock1->Lock();         Lock2->Lock();
WaitForLock2();        WaitForLock1();   <-- Oops!

You generally detect them because things that you expect to happen never do, or the application hangs entirely.

session.flush() is synchronise method means to insert data in to database sequentially.if we use this method data will not store in database but it will store in cache,if any exception will rise in middle we can handle it. But commit() it will store data in database,if we are storing more amount of data then ,there may be chance to get out Of Memory Exception,As like in JDBC program in Save point topic

There second method will be many times more effective (mostly because of compilers inlining and boxing but still numbers are very expressive):

public static bool CheckObjectImpl(object o)
{
    return o != null;
}

public static bool CheckNullableImpl<T>(T? o) where T: struct
{
    return o.HasValue;
}

Benchmark code:

public class BenchmarkNullableCheck
{
    static int? x = (new Random()).Next();

    public static bool CheckObjectImpl(object o)
    {
        return o != null;
    }

    public static bool CheckNullableImpl<T>(T? o) where T: struct
    {
        return o.HasValue;
    }

    [Benchmark]
    public bool CheckObject()
    {
        return CheckObjectImpl(x);
    }

    [Benchmark]
    public bool CheckNullable()
    {
        return CheckNullableImpl(x);
    }
}

https://github.com/dotnet/BenchmarkDotNet was used

So if you have an option (e.g. writing custom serializers) to process Nullable in different pipeline than object - and use their specific properties - do it and use Nullable specific properties. So from consistent thinking point of view HasValue should be preferred. Consistent thinking can help you to write better code do not spending too much time in details.

PS. People say that advice "prefer HasValue because of consistent thinking" is not related and useless. Can you predict the performance of this?

public static bool CheckNullableGenericImpl<T>(T? t) where T: struct
{
    return t != null; // or t.HasValue?
}

PPS People continue minus, seems nobody tries to predict performance of CheckNullableGenericImpl. I will tell you: there compiler will not help you replacing !=null with HasValue. HasValue should be used directly if you are interested in performance.

Assuming there are no prepending/succeeding whitespace characters, there are still a few ways to assert string equality. Some of those are:

• strings.ToLower(..) then ==
• strings.EqualFold(.., ..)
• cases#Lower paired with ==
• cases#Fold paired with ==

Here are some basic benchmark results (in these tests, strings.EqualFold(.., ..) seems like the most performant choice):

Since there are quite a few options, so here's the code to generate benchmarks.

package main

import (
    "fmt"
    "strings"

For Saturday and Sunday You can do something like this

             $('#orderdate').datepicker({
                               daysOfWeekDisabled: [0,6]
                 });

Update For Node / NPM

Add "type": "module" to your package.json

{
  // ...
  "type": "module",
  // ...
}

    HashMap<Integer,String> hs1 = new HashMap<>();
    hs1.put(1,"ram");
    hs1.put(2,"sita");
    hs1.put(3,"laxman");
    hs1.put(4,"hanuman");
    hs1.put(5,"geeta");

    HashMap<Integer,String> hs2 = new HashMap<>();
    hs2.put(5,"rat");
    hs2.put(6,"lion");
    hs2.put(7,"tiger");
    hs2.put(8,"fish");
    hs2.put(9,"hen");

    HashMap<Integer,String> hs3 = new HashMap<>();//Map is which we add

    hs3.putAll(hs1);
    hs3.putAll(hs2);

    System.out.println(" hs1 : " + hs1);
    System.out.println(" hs2 : " + hs2);
    System.out.println(" hs3 : " + hs3);

Duplicate items will not be added(that is duplicate keys) as when we will print hs3 we will get only one value for key 5 which will be last value added and it will be rat. **[Set has a property of not allowing the duplicate key but values can be duplicate]

class foo(object):
    def __str__(self):
        return "representation"
    def __unicode__(self):
        return u"representation"

You should be using datetime.datetime.strptime. Note that very old versions of Python (2.4 and older) don't have datetime.datetime.strptime; use time.strptime in that case.

A very simple way if your code is in Python, where I didn't have to install a Python package, is the following:

\documentclass[11pt]{article}  
\usepackage{pythonhighlight}

\begin{document}

The following is some Python code

\begin{python}
# A comment
x = [5, 7, 10]
y = 0

for num in x:
    y += num
    
print(y)
\end{python}

\end{document}

which looks like:

Unfortunately, this only works for Python.

Non of the above solutions worked for me. I used the code that exists in the documentation of NodeMailer. It looks like this:

let transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true,
    auth: {
        type: 'OAuth2',
        user: '[email protected]',
        serviceClient: '113600000000000000000',
        privateKey: '-----BEGIN PRIVATE KEY-----\nMIIEvgIBADANBg...',
        accessToken: 'ya29.Xx_XX0xxxxx-xX0X0XxXXxXxXXXxX0x',
        expires: 1484314697598
    }
}); 

vw units:

You can use vw units for both the width and height of the element. This allows the element's aspect ratio to be preserved, based on the viewport width.

vw : 1/100th of the width of the viewport. [MDN]

Alternatively, you can also use vh for viewport height, or even vmin/vmax to use the lesser/greater of the viewport dimensions (discussion here).

Example: 1:1 aspect ratio

div {_x000D_
  width: 20vw;_x000D_
  height: 20vw;_x000D_
  background: gold;_x000D_
}

<div></div>

For other aspect ratios, you can use the following table to calculate the value for height according to the width of the element :

aspect ratio  |  multiply width by
-----------------------------------
     1:1      |         1
     1:3      |         3
     4:3      |        0.75
    16:9      |       0.5625

Example: 4x4 grid of square divs

body {_x000D_
  display: flex;_x000D_
  flex-wrap: wrap;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
div {_x000D_
  width: 23vw;_x000D_
  height: 23vw;_x000D_
  margin: 0.5vw auto;_x000D_
  background: gold;_x000D_
}

<div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div>

Here is a Fiddle with this demo and here is a solution to make a responsive grid of squares with verticaly and horizontaly centered content.

Browser support for vh/vw units is IE9+ see canIuse for more info

Step 1: Installing GLFW 3 on your system with CMAKE

For this install, I was using KUbuntu 13.04, 64bit.

The first step is to download the latest version (assuming versions in the future work in a similar way) from www.glfw.org, probably using this link.

The next step is to extract the archive, and open a terminal. cd into the glfw-3.X.X directory and run cmake -G "Unix Makefiles" you may need elevated privileges, and you may also need to install build dependencies first. To do this, try sudo apt-get build-dep glfw or sudo apt-get build-dep glfw3 or do it manually, as I did using sudo apt-get install cmake xorg-dev libglu1-mesa-dev... There may be other libs you require such as the pthread libraries... Apparently I had them already. (See the -l options given to the g++ linker stage, below.)

Now you can type make and then make install, which will probably require you to sudo first.

Okay, you should get some verbose output on the last three CMake stages, telling you what has been built or where it has been placed. (In /usr/include, for example.)

Step 2: Create a test program and compile

The next step is to fire up vim ("what?! vim?!" you say) or your preferred IDE / text editor... I didn't use vim, I used Kate, because I am on KUbuntu 13.04... Anyway, download or copy the test program from here (at the bottom of the page) and save, exit.

Now compile using g++ -std=c++11 -c main.cpp - not sure if c++11 is required but I used nullptr so, I needed it... You may need to upgrade your gcc to version 4.7, or the upcoming version 4.8... Info on that here.

Then fix your errors if you typed the program by hand or tried to be "too clever" and something didn't work... Then link it using this monster! g++ main.o -o main.exec -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi So you see, in the "install build dependencies" part, you may also want to check you have the GL, GLU, X11 Xxf86vm (whatever that is) Xrandr posix-thread and Xi (whatever that is) development libraries installed also. Maybe update your graphics drivers too, I think GLFW 3 may require OpenGL version 3 or higher? Perhaps someone can confirm that? You may also need to add the linker options -ldl -lXinerama -lXcursor to get it to work correctly if you are getting undefined references to dlclose (credit to @user2255242).

And, yes, I really did need that many -ls!

Step 3: You are finished, have a nice day!

Hopefully this information was correct and everything worked for you, and you enjoyed writing the GLFW test program. Also hopefully this guide has helped, or will help, a few people in the future who were struggling as I was today yesterday!

By the way, all the tags are the things I searched for on stackoverflow looking for an answer that didn't exist. (Until now.) Hopefully they are what you searched for if you were in a similar position to myself.

Author Note:

This might not be a good idea. This method (using sudo make install) might be harzardous to your system. (See Don't Break Debian)

Ideally I, or someone else, should propose a solution which does not just install lib files etc into the system default directories as these should be managed by package managers such as apt, and doing so may cause a conflict and break your package management system.

See the new "2020 answer" for an alternative solution.

As I found the default Bootstrap <hr/> size unsightly, here's some simple HTML and CSS to balance out the element visually:

HTML:

<hr class="half-rule"/>

CSS:

.half-rule { 
    margin-left: 0;
    text-align: left;
    width: 50%;
 }

Simple like that.

include the following line in the function to close pop.

$('#youriframeid').remove();

My version of @Merak Marey's Code. I am checking if files exist already and different download directories for .txt and other files

        static void DownloadAll()
    {
        string host = "xxx.xxx.xxx.xxx";
        string username = "@@@";
        string password = "123";string remoteDirectory = "/IN/";
        string finalDir = "";
        string localDirectory = @"C:\filesDN\";
        string localDirectoryZip = @"C:\filesDN\ZIP\";
        using (var sftp = new SftpClient(host, username, password))
        {
            Console.WriteLine("Connecting to " + host + " as " + username);
            sftp.Connect();
            Console.WriteLine("Connected!");
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {

                string remoteFileName = file.Name;

                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today)))
                { 

                    if (!file.Name.Contains(".TXT"))
                    {
                        finalDir = localDirectoryZip;
                    } 
                    else 
                    {
                        finalDir = localDirectory;
                    }


                    if (File.Exists(finalDir  + file.Name))
                    {
                        Console.WriteLine("File " + file.Name + " Exists");
                    }else{
                        Console.WriteLine("Downloading file: " + file.Name);
                          using (Stream file1 = File.OpenWrite(finalDir + remoteFileName))
                    {
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
                    }
                }
            }



            Console.ReadLine();

        }

For me, it helped to link the projects current directory as such:

In the properties -> C++ -> General window, instead of linking the path to the file in "additional include directories". Put "." and uncheck "inheret from parent or project defaults".

Hope this helps.

using JQuery:

myelement=$("#myelement")
[myelement.offset().left, myelement.offset().top,  myelement.width(), myelement.height()]

You need to insert the character code that Excel uses, which IIRC is 10 (ten).

EDIT: OK, here's some code. Note that I was able to confirm that the character-code used is indeed 10, by creating a cell containing:

A

B

...and then selecting it and executing this in the VBA immediate window:

?Asc(Mid(Activecell.Value,2,1))

So, the code you need to insert that value into another cell in VBA would be:

ActiveCell.Value = "A" & vbLf & "B"

(since vbLf is character code 10).

I know you're using C# but I find it's much easier to figure out what to do if you first do it in VBA, since you can try it out "interactively" without having to compile anything. Whatever you do in C# is just replicating what you do in VBA so there's rarely any difference. (Remember that the C# interop stuff is just using the same underlying COM libraries as VBA).

Anyway, the C# for this would be:

oCell.Value = "A\nB";

Spot the difference :-)

EDIT 2: Aaaargh! I just re-read the post and saw that you're using the Aspose library. Sorry, in that case I've no idea.

Google is hosting jQueryUI css at this link https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.all.css

If you look at this code directly, it is importing the css using @import which can be slow. You may want to factor the import into its parts to gain a slight performance benefit:

https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.base.css https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.theme.css

String text = "text";
text += new String(" ");

For Mozilla

input[type=number] { 
    -moz-appearance: textfield;
    appearance: textfield;
    margin: 0; 
}

For Chrome

input[type=number]::-webkit-inner-spin-button, 
input[type=number]::-webkit-outer-spin-button { 
      -webkit-appearance: none; 
      margin: 0; 
}

You can use easy & simple EasyFonts third party library to set variety of custom fonts to your TextView. By using this library you should not have to worry about downloading and adding fonts into the assets/fonts folder. Also about Typeface object creation.

Instead of

Typeface myTypeface = Typeface.createFromAsset(getAssets(), "fonts/myFont.ttf");
TextView myTextView = (TextView)findViewById(R.id.myTextView);
myTextView.setTypeface(myTypeface);

Simply:

TextView myTextView = (TextView)findViewById(R.id.myTextView);
myTextView.setTypeface(EasyFonts.robotoThin(this));

This library also provides following font face.

• Roboto
• Droid Serif
• Droid Robot
• Freedom
• Fun Raiser
• Android Nation
• Green Avocado
• Recognition

Navigate from Error List Tab to the Visual Studios Output folder by one of the following:

• Select tab Output in standard VS view at the bottom
• Click in Menubar View > Output or Ctrl+Alt+O

where Show output from <build> should be selected.

You can find out more by analyzing the output logs.

In my case it was an error in the Cmake step, see below. It could be in any build step, as described in the other answers.

It's as simple as:

s.split("");

The delimiter is an empty string, hence it will break up between each single character.

There is no generic type which will tell the compiler that a method returns nothing.

I believe the convention is to use Object when inheriting as a type parameter

OR

Propagate the type parameter up and then let users of your class instantiate using Object and assigning the object to a variable typed using a type-wildcard ?:

interface B<E>{ E method(); }

class A<T> implements B<T>{

    public T method(){
        // do something
        return null;
    }
}

A<?> a = new A<Object>();

and the implicit comment by many posters => Dont use arrays, use vectors. All of the benefits of arrays with none of the downsides. PLus you get lots of other goodies

If you dont know STL, read Josuttis The C++ standard library and meyers effective STL

I have found a slightly different way implement pointers that is perhaps more general and easier to understand from a C perspective (and thus fits more into the format of the users example).

In JavaScript, like in C, array variables are actually just pointers to the array, so you can use an array as exactly the same as declaring a pointer. This way, all pointers in your code can be used the same way, despite what you named the variable in the original object.

It also allows one to use two different notations referring to the address of the pointer and what is at the address of the pointer.

Here is an example (I use the underscore to denote a pointer):

var _x = [ 10 ];

function foo(_a){
    _a[0] += 10;
}

foo(_x);

console.log(_x[0]);

Yields

output: 20

For me, just setting the compatibility level to higher level works fine. To see C.Level :

select compatibility_level from sys.databases where name = [your_database]

Actually its pretty easy to make integration between Csharp (VS) and Python with IronPython. It's not that much complex... As Chris Dunaway already said in answer section I started to build this inegration for my own project. N its pretty simple. Just follow these steps N you will get your results.

step 1 : Open VS and create new empty ConsoleApp project.

step 2 : Go to tools --> NuGet Package Manager --> Package Manager Console.

step 3 : After this open this link in your browser and copy the NuGet Command. Link: https://www.nuget.org/packages/IronPython/2.7.9

step 4 : After opening the above link copy the PM>Install-Package IronPython -Version 2.7.9 command and paste it in NuGet Console in VS. It will install the supportive packages.

step 5 : This is my code that I have used to run a .py file stored in my Python.exe directory.

step 6 : save and execute the code

In Oracle you can use a collection in the following way:

WHERE EXISTS (SELECT 1
                FROM TABLE(ku$_vcnt('bla%', '%foo%', 'batz%'))
               WHERE something LIKE column_value)

Here I have used a predefined collection type ku$_vcnt, but you can declare your own one like this:

CREATE TYPE my_collection AS TABLE OF VARCHAR2(4000);

It's also useful to note that you can run the underlying MapReduce jobs with either the source or target cluster like so:

hadoop --config /path/to/hadoop/config distcp <src> <dst>

Add a common class to all the div. For example add foo to all the divs.

$('.foo').each(function () {
   $(this).dialog({
    autoOpen: false,
    show: {
      effect: "blind",
      duration: 1000
    },
    hide: {
      effect: "explode",
      duration: 1000
    }
  });
});

For me using the official OpenJDK 12 Docker image, the location of the Java keystore was:

/usr/java/openjdk-12/lib/security/cacerts

Using HTTP with SSL will make your life much easier and you can rest at ease very smart people (smarter than me at least!) have scrutinized this method of confidential communication for years.

raw_input returns a string (a sequence of characters). In Python, multiplying a string and a float makes no defined meaning (while multiplying a string and an integer has a meaning: "AB" * 3 is "ABABAB"; how much is "L" * 3.14 ? Please do not reply "LLL|"). You need to parse the string to a numerical value.

You might want to try:

salesAmount = float(raw_input("Insert sale amount here\n"))

I know this is old but I was looking for the answer in this post and with jquery you can do it easily and without too much hassle. Just declare your animation keyframe in the css and set the class with the atributes you would like. I my case I used the tada animation from css animate:

.tada {
    -webkit-animation-name: tada;
    animation-name: tada;
    -webkit-animation-duration: 1.25s;
    animation-duration: 1.25s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}

I wanted the animation to run every 10 seconds so jquery just adds the class, after 6000ms (enough time for the animation to finish) it removes the class and 4 seconds later it adds the class again and so the animation starts again.

$(document).ready(function() {
  setInterval(function() {

    $(".bottom h2").addClass("tada");//adds the class

    setTimeout(function() {//waits 6 seconds to remove the class
      $(".bottom h2").removeClass("tada");
    }, 6000);

  }, 10000)//repeats the process every 10 seconds
});

Not at all difficult like one guy posted.

You'll have to convert it from dps to pixels using the display scale factor.

final float scale = getContext().getResources().getDisplayMetrics().density;
int pixels = (int) (dps * scale + 0.5f);

While technically correct, the other answers would benefit from an explanation of Angular's URL-to-route matching. I don't think you can fully (pardon the pun) understand what pathMatch: full does if you don't know how the router works in the first place.

Let's first define a few basic things. We'll use this URL as an example: /users/james/articles?from=134#section.

1. It may be obvious but let's first point out that query parameters (?from=134) and fragments (#section) do not play any role in path matching. Only the base url (/users/james/articles) matters.

2. Angular splits URLs into segments. The segments of /users/james/articles are, of course, users, james and articles.

3. The router configuration is a tree structure with a single root node. Each Route object is a node, which may have children nodes, which may in turn have other children or be leaf nodes.

The goal of the router is to find a router configuration branch, starting at the root node, which would match exactly all (!!!) segments of the URL. This is crucial! If Angular does not find a route configuration branch which could match the whole URL - no more and no less - it will not render anything.

E.g. if your target URL is /a/b/c but the router is only able to match either /a/b or /a/b/c/d, then there is no match and the application will not render anything.

Finally, routes with redirectTo behave slightly differently than regular routes, and it seems to me that they would be the only place where anyone would really ever want to use pathMatch: full. But we will get to this later.

Default (prefix) path matching

The reasoning behind the name prefix is that such a route configuration will check if the configured path is a prefix of the remaining URL segments. However, the router is only able to match full segments, which makes this naming slightly confusing.

Anyway, let's say this is our root-level router configuration:

const routes: Routes = [
  {
    path: 'products',
    children: [
      {
        path: ':productID',
        component: ProductComponent,
      },
    ],
  },
  {
    path: ':other',
    children: [
      {
        path: 'tricks',
        component: TricksComponent,
      },
    ],
  },
  {
    path: 'user',
    component: UsersonComponent,
  },
  {
    path: 'users',
    children: [
      {
        path: 'permissions',
        component: UsersPermissionsComponent,
      },
      {
        path: ':userID',
        children: [
          {
            path: 'comments',
            component: UserCommentsComponent,
          },
          {
            path: 'articles',
            component: UserArticlesComponent,
          },
        ],
      },
    ],
  },
];

Note that every single Route object here uses the default matching strategy, which is prefix. This strategy means that the router iterates over the whole configuration tree and tries to match it against the target URL segment by segment until the URL is fully matched. Here's how it would be done for this example:

1. Iterate over the root array looking for a an exact match for the first URL segment - users.
2. 'products' !== 'users', so skip that branch. Note that we are using an equality check rather than a .startsWith() or .includes() - only full segment matches count!
3. :other matches any value, so it's a match. However, the target URL is not yet fully matched (we still need to match james and articles), thus the router looks for children.

• The only child of :other is tricks, which is !== 'james', hence not a match.

4. Angular then retraces back to the root array and continues from there.
5. 'user' !== 'users, skip branch.
6. 'users' === 'users - the segment matches. However, this is not a full match yet, thus we need to look for children (same as in step 3).

• 'permissions' !== 'james', skip it.
• :userID matches anything, thus we have a match for the james segment. However this is still not a full match, thus we need to look for a child which would match articles.
  1. We can see that :userID has a child route articles, which gives us a full match! Thus the application renders UserArticlesComponent.

Full URL (full) matching

Example 1

Imagine now that the users route configuration object looked like this:

{
  path: 'users',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

Note the usage of pathMatch: full. If this were the case, steps 1-5 would be the same, however step 6 would be different:

6. 'users' !== 'users/james/articles - the segment does not match because the path configuration users with pathMatch: full does not match the full URL, which is users/james/articles.
7. Since there is no match, we are skipping this branch.
8. At this point we reached the end of the router configuration without having found a match. The application renders nothing.

Example 2

What if we had this instead:

{
  path: 'users/:userID',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'comments',
      component: UserCommentsComponent,
    },
    {
      path: 'articles',
      component: UserArticlesComponent,
    },
  ],
}

users/:userID with pathMatch: full matches only users/james thus it's a no-match once again, and the application renders nothing.

Example 3

Let's consider this:

{
  path: 'users',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      pathMatch: 'full',
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

In this case:

6. 'users' === 'users - the segment matches, but james/articles still remains unmatched. Let's look for children.

• 'permissions' !== 'james' - skip.
• :userID' can only match a single segment, which would be james. However, it's a pathMatch: full route, and it must match james/articles (the whole remaining URL). It's not able to do that and thus it's not a match (so we skip this branch)!

7. Again, we failed to find any match for the URL and the application renders nothing.

As you may have noticed, a pathMatch: full configuration is basically saying this:

Ignore my children and only match me. If I am not able to match all of the remaining URL segments myself, then move on.

Redirects

Any Route which has defined a redirectTo will be matched against the target URL according to the same principles. The only difference here is that the redirect is applied as soon as a segment matches. This means that if a redirecting route is using the default prefix strategy, a partial match is enough to cause a redirect. Here's a good example:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

For our initial URL (/users/james/articles), here's what would happen:

1. 'not-found' !== 'users' - skip it.
2. 'users' === 'users' - we have a match.
3. This match has a redirectTo: 'not-found', which is applied immediately.
4. The target URL changes to not-found.
5. The router begins matching again and finds a match for not-found right away. The application renders NotFoundComponent.

Now consider what would happen if the users route also had pathMatch: full:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    pathMatch: 'full',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

1. 'not-found' !== 'users' - skip it.
2. users would match the first segment of the URL, but the route configuration requires a full match, thus skip it.
3. 'users/:userID' matches users/james. articles is still not matched but this route has children.

• We find a match for articles in the children. The whole URL is now matched and the application renders UserArticlesComponent.

Empty path (path: '')

The empty path is a bit of a special case because it can match any segment without "consuming" it (so it's children would have to match that segment again). Consider this example:

const routes: Routes = [
  {
    path: '',
    children: [
      {
        path: 'users',
        component: BadUsersComponent,
      }
    ]
  },
  {
    path: 'users',
    component: GoodUsersComponent,
  },
];

Let's say we are trying to access /users:

• path: '' will always match, thus the route matches. However, the whole URL has not been matched - we still need to match users!
• We can see that there is a child users, which matches the remaining (and only!) segment and we have a full match. The application renders BadUsersComponent.

Now back to the original question

The OP used this router configuration:

const routes: Routes = [
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
  {
    path: '',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
  {
    path: '**',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
];

If we are navigating to the root URL (/), here's how the router would resolve that:

1. welcome does not match an empty segment, so skip it.
2. path: '' matches the empty segment. It has a pathMatch: 'full', which is also satisfied as we have matched the whole URL (it had a single empty segment).
3. A redirect to welcome happens and the application renders WelcomeComponent.

What if there was no pathMatch: 'full'?

Actually, one would expect the whole thing to behave exactly the same. However, Angular explicitly prevents such a configuration ({ path: '', redirectTo: 'welcome' }) because if you put this Route above welcome, it would theoretically create an endless loop of redirects. So Angular just throws an error, which is why the application would not work at all! (https://angular.io/api/router/Route#pathMatch)

Actually, this does not make too much sense to me because Angular also has implemented a protection against such endless redirects - it only runs a single redirect per routing level! This would stop all further redirects (as you'll see in the example below).

What about path: '**'?

path: '**' will match absolutely anything (af/frewf/321532152/fsa is a match) with or without a pathMatch: 'full'.

Also, since it matches everything, the root path is also included, which makes { path: '', redirectTo: 'welcome' } completely redundant in this setup.

Funnily enough, it is perfectly fine to have this configuration:

const routes: Routes = [
  {
    path: '**',
    redirectTo: 'welcome'
  },
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
];

If we navigate to /welcome, path: '**' will be a match and a redirect to welcome will happen. Theoretically this should kick off an endless loop of redirects but Angular stops that immediately (because of the protection I mentioned earlier) and the whole thing works just fine.

One way would be to convert both strings to upper or lower:

test $(echo "string" | /bin/tr '[:upper:]' '[:lower:]') = $(echo "String" | /bin/tr '[:upper:]' '[:lower:]') && echo same || echo different

Another way would be to use grep:

echo "string" | grep -qi '^String$' && echo same || echo different

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

I think the reason it doesn't work has something to do with the fact that you have the right position set, but not the left.

If you manually set the left to the current position, it seems to go:

Live example: http://jsfiddle.net/XqqtN/

var left = $('#coolDiv').offset().left;  // Get the calculated left position

$("#coolDiv").css({left:left})  // Set the left to its calculated position
             .animate({"left":"0px"}, "slow");

EDIT:

Appears as though Firefox behaves as expected because its calculated left position is available as the correct value in pixels, whereas Webkit based browsers, and apparently IE, return a value of auto for the left position.

Because auto is not a starting position for an animation, the animation effectively runs from 0 to 0. Not very interesting to watch. :o)

Setting the left position manually before the animate as above fixes the issue.

If you don't like cluttering the landscape with variables, here's a nice version of the same thing that obviates the need for a variable:

$("#coolDiv").css('left', function(){ return $(this).offset().left; })
             .animate({"left":"0px"}, "slow");    ?

I looked all over for an easy solution and found this code that worked for me. The right div is a third column which I left in for readability sake.

Here is the HTML:

<div class="container">
  <div class="row">
    <div class="left">
      <p>PHONE & FAX:</p>
    </div>
    <div class="middle">
      <p>+43 99 554 28 53</p>
    </div>
    <div class="right"> </div>
  </div>
  <div class="row">
    <div class="left">
      <p>Cellphone Gert:</p>
    </div>
    <div class="middle">
      <p>+43 99 302 52 32</p>
    </div>
    <div class="right"> </div>
  </div>
  <div class="row">
    <div class="left">
      <p>Cellphone Petra:</p>
    </div>
    <div class="middle">
      <p>+43 99 739 38 84</p>
    </div>
    <div class="right"> </div>
  </div>
</div>

And the CSS:

.container {
    display: table;
    }
.row  {
    display: table-row;
    }
.left, .right, .middle {
    display: table-cell;
    padding-right: 25px;
    }
.left p, .right p, .middle p {
    margin: 1px 1px;
   }

try: var cc = @Html.Raw(Json.Encode(ViewBag.CC)

If you have multiple occurrences of an element name, then you have to use forEach().

html

  <input type="checkbox" name="delete" id="flizzit" />
  <input type="checkbox" name="delete" id="floo" />
  <input type="checkbox" name="delete" id="flum" />
  <input type="submit" value="Save"  onClick={evt => saveAction(evt)}></input>

js

const submitAction = (evt) => {
  evt.preventDefault();
  const dels = evt.target.parentElement.delete;
  const deleted = [];
  dels.forEach((d) => { if (d.checked) deleted.push(d.id); });
  window.alert(deleted.length);
};

Note the dels in this case is a RadioNodeList, not an array, and is not an Iterable. The forEach()is a built-in method of the list class. You will not be able to use a map() or reduce() here.

Please check that your key exists in the array or not, instead of simply trying to access it.

Replace:

$myVar = $someArray['someKey']

With something like:

if (isset($someArray['someKey'])) {
    $myVar = $someArray['someKey']
}

or something like:

if(is_array($someArray['someKey'])) {
    $theme_img = 'recent_works_iso_thumbnail';
}else {
    $theme_img = 'recent_works_iso_thumbnail';
}

<form id="myform">
    <input type="textbox" id="field"/>
    <input type="button" value="submit">
</form>

<script>
    $(function () {
        $("#field").keyup(function (event) {
            if (event.which === 13) {
                document.myform.submit();
            }
        }
    });
</script>

You can also write a custom query using @Query

@Query(value = "from EntityClassTable t where yourDate BETWEEN :startDate AND :endDate")
public List<EntityClassTable> getAllBetweenDates(@Param("startDate")Date startDate,@Param("endDate")Date endDate);

This is the easiest possible way. If form is posted via post, do php function. Note that if you want to perform function asynchronously (without the need to reload the page), then you'll need AJAX.

<form method="post">
    <button name="test">test</button>
</form>

    <?php
    if(isset($_POST['test'])){
      //do php stuff  
    }
    ?>

For dropped packets I would simply use iptables and the statistic module.

iptables -A INPUT -m statistic --mode random --probability 0.01 -j DROP

Above will drop an incoming packet with a 1% probability. Be careful, anything above about 0.14 and most of you tcp connections will most likely stall completely.

Take a look at man iptables and search for "statistic" for more information.
