Every canvas item is an object that Tkinter keeps track of. If you are clearing the screen by just drawing a black rectangle, then you effectively have created a memory leak -- eventually your program will crash due to the millions of items that have been drawn.

To clear a canvas, use the delete method. Give it the special parameter "all" to delete all items on the canvas (the string "all"" is a special tag that represents all items on the canvas):

canvas.delete("all")

If you want to delete only certain items on the canvas (such as foreground objects, while leaving the background objects on the display) you can assign tags to each item. Then, instead of "all", you could supply the name of a tag.

If you're creating a game, you probably don't need to delete and recreate items. For example, if you have an object that is moving across the screen, you can use the move or coords method to move the item.

I know this is a super old post, but I figured this may still be helpful.

If you're comfortable with reading json format you could replace your var_dump with:

return json_encode($myvar);

I've been using this to help troubleshoot a service I've been building that has some deeply nested arrays. This will return every level of your array without truncating anything or requiring you to change your php.ini file.

Also, because the json_encoded data is a string it means you can write it to the error log easily

error_log(json_encode($myvar));

It probably isn't the best choice for every situation, but it's a choice!

Sometimes the crash itself isn't the real cause of the problem-- perhaps the memory got smashed at an earlier point but it took a while for the corruption to show itself. Check out valgrind, which has lots of checks for pointer problems (including array bounds checking). It'll tell you where the problem starts, not just the line where the crash occurs.

Looks like the setup.py uses easy_install (i.e. setuptools). Just install the setuptools package and you will be all set.

To install setuptools in Python 2.6, see the answer to this question.

Copying the answer from Chris:

Got it working:

import {AfterViewInit} from 'angular2/core';    

export class HomeCmp implements AfterViewInit {    

    ngAfterViewInit() {
       //Copy in all the js code from the script.js. Typescript will complain but it works just fine
    }

try lcut! - http://code.google.com/p/lcut

The 'c' means it's a character special file.

__init__ is a special method in Python classes, it is the constructor method for a class. It is called whenever an object of the class is constructed or we can say it initialises a new object. Example:

    In [4]: class A:
   ...:     def __init__(self, a):
   ...:         print(a)
   ...:
   ...: a = A(10) # An argument is necessary
10

If we use A(), it will give an error TypeError: __init__() missing 1 required positional argument: 'a' as it requires 1 argument a because of __init__ .

........

__call__ when implemented in the Class helps us invoke the Class instance as a function call.

Example:

In [6]: class B:
   ...:     def __call__(self,b):
   ...:         print(b)
   ...:
   ...: b = B() # Note we didn't pass any arguments here
   ...: b(20)   # Argument passed when the object is called
   ...:
20

Here if we use B(), it runs just fine because it doesn't have an __init__ function here.

The difference between http and https is that https requests are sent over an ssl-encrypted connection. The ssl-encrypted connection must be established between the browser and the server before the browser sends the http request.

Https requests are in fact http requests that are sent over an ssl encrypted connection. If the server rejects to establish an ssl encrypted connection then the browser will have no connection to send the request over. The browser and the server will have no way of talking to each other. The browser will not be able to send the url that it wants to access and the server will not be able to respond with a redirect to another url.

So this is not possible. If you want to respond to https links, then you need an ssl certificate.

Not the answer for this question

I got this exception when trying to delete a folder where i deleted the file inside.

Example:

createFolder("folder");  
createFile("folder/file");  
deleteFile("folder/file");  
deleteFolder("folder"); // error here

While deleteFile("folder/file"); returned that it was deleted, the folder will only be considered empty after the program restart.

On some operating systems it may not be possible to remove a file when it is open and in use by this Java virtual machine or other programs.

Explanation from dhke

I've found this page on their github repo, I'll just paste the content here.

Recommended approach for saving a model

There are two main approaches for serializing and restoring a model.

The first (recommended) saves and loads only the model parameters:

torch.save(the_model.state_dict(), PATH)

Then later:

the_model = TheModelClass(*args, **kwargs)
the_model.load_state_dict(torch.load(PATH))

The second saves and loads the entire model:

torch.save(the_model, PATH)

Then later:

the_model = torch.load(PATH)

However in this case, the serialized data is bound to the specific classes and the exact directory structure used, so it can break in various ways when used in other projects, or after some serious refactors.

if you found out that the memory settings were not being used and in order to change the memory settings, I used the tomcat7w or tomcat8w in the \bin folder.Then the following should pop up:

Click the Java tab and add the arguments.restart tomcat

CSV isn't quite that simple. Depending on the limits of the data you have, you might have to worry about quoted values (which may contain commas and newlines) and escaping quotes.

So if your data are restricted enough can get away with simple comma-splitting fine, shell script can do that easily. If, on the other hand, you need to parse CSV ‘properly’, bash would not be my first choice. Instead I'd look at a higher-level scripting language, for example Python with a csv.reader.

On macOS, none of the answers worked for me. I discovered that was due to differences in how sed works on macOS and other BSD systems compared to GNU.

In particular BSD sed takes the -i option but requires a suffix for the backup (but an empty suffix is permitted)

grep version from this answer.

grep -rl 'foo' ./ | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

find version from this answer.

find . \( ! -regex '.*/\..*' \) -type f | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

Don't omit the Regex to ignore . folders if you're in a Git repo. I realized that the hard way!

That LC_ALL=C option is to avoid getting sed: RE error: illegal byte sequence if sed finds a byte sequence that is not a valid UTF-8 character. That's another difference between BSD and GNU. Depending on the kind of files you are dealing with, you may not need it.

For some reason that is not clear to me, the grep version found more occurrences than the find one, which is why I recommend to use grep.

What you are probably really wanting to do here is use the union operator like this:

(select ID from Logo where AccountID = 1 and Rendered = 'True')
  union
  (select ID from Design where AccountID = 1 and Rendered = 'True')
  order by ID limit 0, 51

Here's the docs for it https://dev.mysql.com/doc/refman/5.0/en/union.html

If you need to set the user header string in the curl request, you can use the -H option to set user agent like:

curl -H "user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36" http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Using a proxy tool like Charles Proxy really helps make short work of something like what you are asking. Here is what I do, using this SO page as an example (as of July 2015 using Charles version 3.10):

1. Get Charles Proxy running
2. Make web request using browser
3. Find desired request in Charles Proxy
4. Right click on request in Charles Proxy
5. Select 'Copy cURL Request'

You now have a cURL request you can run in a terminal that will mirror the request your browser made. Here is what my request to this page looked like (with the cookie header removed):

curl -H "Host: stackoverflow.com" -H "Cache-Control: max-age=0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" -H "HTTPS: 1" -H "DNT: 1" -H "Referer: https://www.google.com/" -H "Accept-Language: en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4" -H "If-Modified-Since: Thu, 23 Jul 2015 20:31:28 GMT" --compressed http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Use the FormBorderStyle property. Make it FixedSingle:

this.FormBorderStyle = FormBorderStyle.FixedSingle;

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

for me, this worked

exec utl_mail.send@myotherdb(
  sender => '[email protected]',recipients => '[email protected], 
  cc => null, subject => 'my subject', message => 'my message'
); 

based on @CanalDoMestre's answer. I added support for the blank filter case, fixed a typo and prevented hiding the rows so I can still see the column headers.

    $("#filterby").on('keyup', function() {
        if (this.value.length < 1) {
            $("#list tr").css("display", "");
        } else {
            $("#list tbody tr:not(:contains('"+this.value+"'))").css("display", "none");
            $("#list tbody tr:contains('"+this.value+"')").css("display", "");
        }
    });

The calculation of the zoom level for the longitudes of Giles Gardam works fine for me. If you want to calculate the zoom factor for latitude, this is an easy solution that works fine:

double minLat = ...;
double maxLat = ...;
double midAngle = (maxLat+minLat)/2;
//alpha is the non-negative angle distance of alpha and beta to midangle
double alpha  = maxLat-midAngle;
//Projection screen is orthogonal to vector with angle midAngle
//portion of horizontal scale:
double yPortion = Math.sin(alpha*Math.pi/180) / 2;
double latZoom = Math.log(mapSize.height / GLOBE_WIDTH / yPortion) / Math.ln2;

//return min (max zoom) of both zoom levels
double zoom = Math.min(lngZoom, latZoom);

DateTime.Now.Ticks is not safe, Guid.NewGuid() is too ugly, if you need something clean and almost safe (it's not 100% safe for example if you call it 1,000,000 times in 1ms), try:

Math.Abs(Guid.NewGuid().GetHashCode())

By safe I mean safe to be unique when you call it so many times in very short period few ms of time.

You can call [aDictionary description], or anywhere you would need a format string, just use %@ to stand in for the dictionary:

[NSString stringWithFormat:@"my dictionary is %@", aDictionary];

or

NSLog(@"My dictionary is %@", aDictionary);

This is what worked for me in KitKat and with good results.

public static void setTaskBarColored(Activity context) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
        {
            Window w = context.getWindow();
            w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            //status bar height
            int statusBarHeight = Utilities.getStatusBarHeight(context);

            View view = new View(context);
            view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
            view.getLayoutParams().height = statusBarHeight;
            ((ViewGroup) w.getDecorView()).addView(view);
            view.setBackgroundColor(context.getResources().getColor(R.color.colorPrimaryTaskBar));
        }
    }

It means that you have a memory error. You may be trying to free a pointer that wasn't allocated by malloc (or delete an object that wasn't created by new) or you may be trying to free/delete such an object more than once. You may be overflowing a buffer or otherwise writing to memory to which you shouldn't be writing, causing heap corruption.

Any number of programming errors can cause this problem. You need to use a debugger, get a backtrace, and see what your program is doing when the error occurs. If that fails and you determine you have corrupted the heap at some previous point in time, you may be in for some painful debugging (it may not be too painful if the project is small enough that you can tackle it piece by piece).

It creates a hidden input on the form for the field (from your model) that you pass it.

It is useful for fields in your Model/ViewModel that you need to persist on the page and have passed back when another call is made but shouldn't be seen by the user.

Consider the following ViewModel class:

public class ViewModel
{
    public string Value { get; set; }
    public int Id { get; set; }
}

Now you want the edit page to store the ID but have it not be seen:

<% using(Html.BeginForm() { %>
    <%= Html.HiddenFor(model.Id) %><br />
    <%= Html.TextBoxFor(model.Value) %>
<% } %>

This results in the equivalent of the following HTML:

<form name="form1">
    <input type="hidden" name="Id">2</input>
    <input type="text" name="Value" value="Some Text" />
</form>

If what you're looking for is a way to append a vector to another after creation, vector::insert is your best bet, as has been answered several times, for example:

vector<int> first = {13};
const vector<int> second = {42};

first.insert(first.end(), second.cbegin(), second.cend());

Sadly there's no way to construct a const vector<int>, as above you must construct and then insert.

If what you're actually looking for is a container to hold the concatenation of these two vector<int>s, there may be something better available to you, if:

1. Your vector contains primitives
2. Your contained primitives are of size 32-bit or smaller
3. You want a const container

If the above are all true, I'd suggest using the basic_string who's char_type matches the size of the primitive contained in your vector. You should include a static_assert in your code to validate these sizes stay consistent:

static_assert(sizeof(char32_t) == sizeof(int));

With this holding true you can just do:

const u32string concatenation = u32string(first.cbegin(), first.cend()) + u32string(second.cbegin(), second.cend());

For more information on the differences between string and vector you can look here: https://stackoverflow.com/a/35558008/2642059

For a live example of this code you can look here: http://ideone.com/7Iww3I

Either increase the ram size allocated while doing HAX installation , so as to fit exactly or a bit more higher space than the ram size of the emulator which you want to launch in "Intel x86 Emulator Accelerator (HAXM) " mode,

Once you succeed with that, you can now able to view this in the console /log

printf("%.<number>f", myFloat) //where <number> - digit after comma

http://www.cplusplus.com/reference/clibrary/cstdio/printf/

By default, the layouts in /res/layout are applied to both portrait and landscape.

If you have for example

/res/layout/main.xml

you can add a new folder /res/layout-land, copy main.xml into it and make the needed adjustments.

According to the Java docs, it looks like you need to use the MemoryImageSource Class to put your byte array into an object in memory, and then use Component.createImage(ImageProducer) next (passing in your MemoryImageSource, which implements ImageProducer).

You can get posted form data from request.form and query string data from request.args.

myvar =  request.form["myvar"]

myvar = request.args["myvar"]

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

None of the above solutions were suitable for my scenario, handling .Navigated and .FileDownload events seemed like a good fit but accessing the WebBrowser.Document property threw an UnauthorizedAccessException which is caused by cross frame scripting security (our web content contains frames - all on the same domain/address but frames have their own security holes that are being blocked).

I've added three custom commands: git tree, git stree and git vtree. I'll go over them in that order.

[alias]
    tree = log --all --graph --decorate=short --color --format=format:'%C(bold blue)%h%C(reset) %C(auto)%d%C(reset)\n         %C(black)[%cr]%C(reset)  %x09%C(black)%an: %s %C(reset)'

With git stree and git vtree I've use bash to help with the formatting.

[alias]
    logx = log --all --graph --decorate=short --color --format=format:'%C(bold blue)%h%C(reset)+%C(dim black)(%cr)%C(reset)+%C(auto)%d%C(reset)++\n+++       %C(bold black)%an%C(reset)%C(black): %s%C(reset)'

        while IFS=+ read -r hash time branch message; do                                            \

EDIT: This works with git version 1.9a. The color value 'auto' is apparently making its debut in this release. It's a nice addition because branch names will get a different color. This makes it easier to distinguish between local and remote branches for instance.

I was looking for something like a LinkedHashMap in Java. Neither Swift nor Objective-C have one if I'm not mistaken.

My initial thought was to wrap my dictionary in an Array. [[String: UIImage]] but then I realized that grabbing the key from the dictionary was wacky with Array(dict)[index].key so I went with Tuples. Now my array looks like [(String, UIImage)] so I can retrieve it by tuple.0. No more converting it to an Array. Just my 2 cents.

While none of these answers worked for me, I was able to fix the issue using the following command.

git fetch origin

This did a trick for me.

This works but password length should be exactly 8. This is simple and requires pyDes.

from pyDes import *

def encode(data,password):
    k = des(password, CBC, "\0\0\0\0\0\0\0\0", pad=None, padmode=PAD_PKCS5)
    d = k.encrypt(data)
    return d

def decode(data,password):
    k = des(password, CBC, "\0\0\0\0\0\0\0\0", pad=None, padmode=PAD_PKCS5)
    d = k.decrypt(data)
    return d

x = encode('John Doe', 'mypass12')
y = decode(x,'mypass12')

print x
print y

OUTPUT:

³.\Þ\åS¾+æÅ`;Ê
John Doe

Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.

Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.

The answer to my question is at Ansible: best practice for maintaining list of sudoers.

The Ansible playbook code fragment looks like this from my problem:

- name: Make sure we have a 'wheel' group
  group:
    name: wheel
    state: present

- name: Allow 'wheel' group to have passwordless sudo
  lineinfile:
    dest: /etc/sudoers
    state: present
    regexp: '^%wheel'
    line: '%wheel ALL=(ALL) NOPASSWD: ALL'
    validate: 'visudo -cf %s'

- name: Add sudoers users to wheel group
  user:
    name=deployer
    groups=wheel
    append=yes
    state=present
    createhome=yes

- name: Set up authorized keys for the deployer user
  authorized_key: user=deployer key="{{item}}"
  with_file:
    - /home/railsdev/.ssh/id_rsa.pub

And the best part is that the solution is idempotent. It doesn't add the line

%wheel ALL=(ALL) NOPASSWD: ALL

to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.

You can do it the OO way, just an alternative and flexible:

class Logger {

    private
        $file,
        $timestamp;

    public function __construct($filename) {
        $this->file = $filename;
    }

    public function setTimestamp($format) {
        $this->timestamp = date($format)." » ";
    }

    public function putLog($insert) {
        if (isset($this->timestamp)) {
            file_put_contents($this->file, $this->timestamp.$insert."<br>", FILE_APPEND);
        } else {
            trigger_error("Timestamp not set", E_USER_ERROR);
        }
    }

    public function getLog() {
        $content = @file_get_contents($this->file);
        return $content;
    }

}

Then use it like this .. let's say you have user_name stored in a session (semi pseudo code):

$log = new Logger("log.txt");
$log->setTimestamp("D M d 'y h.i A");

if (user logs in) {
    $log->putLog("Successful Login: ".$_SESSION["user_name"]);
}
if (user logs out) {
    $log->putLog("Logout: ".$_SESSION["user_name"]);
}

Check your log with this:

$log->getLog();

Result is like:

Sun Jul 02 '17 05.45 PM » Successful Login: JohnDoe
Sun Jul 02 '17 05.46 PM » Logout: JohnDoe

Starting with C++20, you can use the starts_with method.

std::string s = "abcd";
if (s.starts_with("abc")) {
    ...
}

Be aware that random.shuffle() should not be used on multi-dimensional arrays as it causes repetitions.

Imagine you want to shuffle an array along its first dimension, we can create the following test example,

import numpy as np
x = np.zeros((10, 2, 3))

for i in range(10):
   x[i, ...] = i*np.ones((2,3))

so that along the first axis, the i-th element corresponds to a 2x3 matrix where all the elements are equal to i.

If we use the correct shuffle function for multi-dimensional arrays, i.e. np.random.shuffle(x), the array will be shuffled along the first axis as desired. However, using random.shuffle(x) will cause repetitions. You can check this by running len(np.unique(x)) after shuffling which gives you 10 (as expected) with np.random.shuffle() but only around 5 when using random.shuffle().

Both are fine, but only the first one will allow you to inspect the Exception itself.

Both swallow the Exception, and you should only catch exceptions to do something meaningfull. Hiding a problem is not meaningful!

Try to use this with single quotes in data:

insert into table test_hive values ('1','puneet');

Like Vatine wrote: Since go lacks generics it would have to be part of the language and not the standard library. For that you would then have to pollute the language with keywords set, union, intersection, difference, subset...

The other reason is, that it's not clear at all what the "right" implementation of a set is:

1. There is a functional approach:

   func IsInEvenNumbers(n int) bool {
       if n % 2 == 0 {
           return true
       }
      return false
   }
   

This is a set of all even ints. It has a very efficient lookup and union, intersect, difference and subset can easily be done by functional composition.

2. Or you do a has-like approach like Dali showed.

A map does not have that problem, since you store something associated with the value.

Whomever gets nothing back, I think he just has to enclose the result in html tags,

Like this:

<html>
<head></head>
<body>
<?php
echo $_GET['link'];
?>
<body>
</html>

Try this instead:

  =SUM(IF(MONTH($A$2:$A$6)=1,$B$2:$B$6,0))

It's an array formula, so you will need to enter it with the Control-Shift-Enter key combination.

Here's how the formula works.

1. MONTH($A$2:$A$6) creates an array of numeric values of the month for the dates in A2:A6, that is,
   {1, 1, 1, 2, 2}.
2. Then the comparison {1, 1, 1, 2, 2}= 1 produces the array {TRUE, TRUE, TRUE, FALSE, FALSE}, which comprises the condition for the IF statement.
3. The IF statement then returns an array of values, with {430, 96, 400.. for the values of the sum ranges where the month value equals 1 and ..0,0} where the month value does not equal 1.
4. That array {430, 96, 400, 0, 0} is then summed to get the answer you are looking for.

This is essentially equivalent to what the SUMIF and SUMIFs functions do. However, neither of those functions support the kind of calculation you tried to include in the conditional.

It's also possible to drop the IF completely. Since TRUE and FALSE can also be treated as 1 and 0, this formula--=SUM((MONTH($A$2:$A$6)=1)*$B$2:$B$6)--also works.

Heads up: This does not work in Google Spreadsheets

Parse a filename from the fully qualified path name (e.g., c:\temp\my.bat) to any component (e.g., File.ext).

Single line of code:

For %%A in ("C:\Folder1\Folder2\File.ext") do (echo %%~fA)

You can change out "C:\Folder1\Folder2\File.ext" for any full path and change "%%~fA" for any of the other options you will find by running "for /?" at the command prompt.

Elaborated Code

set "filename=C:\Folder1\Folder2\File.ext"
For %%A in ("%filename%") do (
    echo full path: %%~fA
    echo drive: %%~dA
    echo path: %%~pA
    echo file name only: %%~nA
    echo extension only: %%~xA
    echo expanded path with short names: %%~sA
    echo attributes: %%~aA
    echo date and time: %%~tA
    echo size: %%~zA
    echo drive + path: %%~dpA
    echo name.ext: %%~nxA
    echo full path + short name: %%~fsA)

Just like I have a device 1080x1920

The vertical number we calculate from height **hp**
height:200
200/1920*100 = 10.41% - height:hp("10.41%")


The Horizontal number we calculate from width **wp**
width:200
200/1080*100 = 18.51% - Width:wp("18.51%")

It's working for all device

var btn = document.getElementById('btn-test');
var event = new Event(null);

event.initEvent('beforeinstallprompt', true, true);
btn.addEventListener('beforeinstallprompt', null, false);
btn.dispatchEvent(event);

this will imediattely trigger an event 'beforeinstallprompt'

A __pycache__ folder is created when you use the line:

import file_name

or try to get information from another file you have created. This makes it a little faster when running your program the second time to open the other file.

To rotate a DIV Make use of WebkitTransform / -moz-transform: rotate(Xdeg).

This will not work in IE. The Raphael library does work with IE and it does rotation. I believe it uses canvases

If you want to animate the rotation, you can use a recursive setTimeout()

You could probably even do part of a spin with jQuery's .animate()

Make sure that you consider the width of your element. If rotate an that has a larger width than its visible content, you'll get funny results. However you can narrow the widths of elements, and then rotate them.

Here is a simply jQuery snippet that rotates the elements in a jQuery object. Rotatation can be started and stopped:

$(function() {
    var $elie = $(selectorForElementsToRotate);
    rotate(0);
    function rotate(degree) {

          // For webkit browsers: e.g. Chrome
        $elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
          // For Mozilla browser: e.g. Firefox
        $elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});

          // Animate rotation with a recursive call
        setTimeout(function() { rotate(++degree); },5);
    }
});

Taking the degree and increasing it, will rotate the image clockwise. Decreasing the degree of rotation will rotate the image counter clockwise.

You can' just add a class to each of your DIVs and apply the rule to the class in this way:

HTML:

<div class="myclass" id="s1">...</div>
<div class="myclass" id="s2">...</div>

CSS:

//css
.myclass
{
   ...
}

You could use CAST or CONVERT:

SELECT CAST(MyVarcharCol AS INT) FROM Table

SELECT CONVERT(INT, MyVarcharCol) FROM Table

The page to do this is at https://developers.facebook.com/tools/debug/ and has changed slightly since some of the other answers.

Paste your URL in there and hit "Debug". Then hit the "Fetch new scrape information" button under the URL text field and you should be all set. It'll pull the fresh meta tags from your page, but they'll still cache so keep in mind you'll need to do this whenever you change them. This is really critical if you are playing with the meta tags to get FB Shared URLs to format the way you want them to inside of facebook.

Quote your args in Testscript 1:

echo "TestScript1 Arguments:"
echo "$1"
echo "$2"
echo "$#"
./testscript2 "$1" "$2"

Static methods should be called on the Class, Instance methods should be called on the Instances of the Class. But what does that mean in reality? Here is a useful example:

A car class might have an instance method called Accelerate(). You can only Accelerate a car, if the car actually exists (has been constructed) and therefore this would be an instance method.

A car class might also have a count method called GetCarCount(). This would return the total number of cars created (or constructed). If no cars have been constructed, this method would return 0, but it should still be able to be called, and therefore it would have to be a static method.

Kindly check Column ApplicationId datatype in Table aspnet_Users , ApplicationId column datatype should be uniqueidentifier .

*Your parameter order is passed wrongly , Parameter @id should be passed as first argument, but in your script it is placed in second argument..*

So error is raised..

Please refere sample script:

DECLARE @id uniqueidentifier
SET @id = NEWID()
Create Table #temp1(AppId uniqueidentifier)

insert into #temp1 values(@id)

Select * from #temp1

Drop Table #temp1

Seems like a bad way to do it (creating two correlated lists) but I'm assuming you have your reasons.

I'd parse the JSON string (which has a typo in your example, it's missing a comma between the two objects) into a strongly-typed object and then use a couple of LINQ queries to get the two lists.

void Main()
{
    string json = "{\"People\":[{\"FirstName\":\"Hans\",\"LastName\":\"Olo\"},{\"FirstName\":\"Jimmy\",\"LastName\":\"Crackedcorn\"}]}";

    var result = JsonConvert.DeserializeObject<RootObject>(json);

    var firstNames = result.People.Select (p => p.FirstName).ToList();
    var lastNames = result.People.Select (p => p.LastName).ToList();
}

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class RootObject
{
    public List<Person> People { get; set; }
}

To plot an equation that is not solved for a specific variable (like circle or hyperbola):

import numpy as np  
import matplotlib.pyplot as plt  
plt.figure() # Create a new figure window
xlist = np.linspace(-2.0, 2.0, 100) # Create 1-D arrays for x,y dimensions
ylist = np.linspace(-2.0, 2.0, 100) 
X,Y = np.meshgrid(xlist, ylist) # Create 2-D grid xlist,ylist values
F = X**2 + Y**2 - 1  #  'Circle Equation
plt.contour(X, Y, F, [0], colors = 'k', linestyles = 'solid')
plt.show()

After nearly a decade of work — with proposals, proofs-of-concept, discussions and other contributions by the broader web developer community — the CSS Working Group has finally laid some of the groundwork needed for container queries to be written into a future edition of the CSS Containment spec! For more details on how such a feature might work and be used, check out Miriam Suzanne's extensive explainer.

Hopefully it won't be much longer before we see a robust cross-browser implementation of such a system. It's been a grueling wait, but I'm glad that it's no longer something we simply have to accept as an insurmountable limitation of CSS due to cyclic dependencies or infinite loops or what have you (these are still a potential issue in some aspects of the proposed design, but I have faith that the CSSWG will find a way).

Media queries aren't designed to work based on elements in a page. They are designed to work based on devices or media types (hence why they are called media queries). width, height, and other dimension-based media features all refer to the dimensions of either the viewport or the device's screen in screen-based media. They cannot be used to refer to a certain element on a page.

If you need to apply styles depending on the size of a certain div element on your page, you'll have to use JavaScript to observe changes in the size of that div element instead of media queries.

Alternatively, with more modern layout techniques introduced since the original publication of this answer such as flexbox and standards such as custom properties, you may not need media or element queries after all. Djave provides an example.

Search your installation of PhpMyAdmin for a file called Documentation.txt. This describes how to create a file called config.inc.php and how you can configure the username and password.

I tried all answers but nothing worked for me. I ended up connecting to different WiFi network then I was able to debug wirelessly.

I have no clue why it didn't work with the old network

Try to replace the

padding: 2px 30px 2px 2px;

with

padding: 2px 2px 2px 2px;

It should work.

Use the following command on the your command line:

fsutil file createnew filename  requiredSize

The parameters info as followed:

fsutil - File system utility ( the executable you are running )

file - triggers a file action

createnew - the action to perform (create a new file)

filename - would be literally the name of the file

requiredSize - would allocate a file size in bytes in the created file

Add /Q for quiet mode and it should remove the prompt.

With the release of Android 2.3 (Gingerbread), you can now use the android.hardware.Camera class to get the number of cameras, information about a specific camera, and get a reference to a specific Camera. Check out the new Camera APIs here.

Assuming that c++ code (c++11) is okay as well and the interface is known.

#include <cstdint>
#include <fstream>
#include <streambuf>
#include <regex>

using namespace std;

uint64_t getIFMAC(const string &ifname) {
  ifstream iface("/sys/class/net/" + ifname + "/address");
  string str((istreambuf_iterator<char>(iface)), istreambuf_iterator<char>());
  if (str.length() > 0) {
    string hex = regex_replace(str, std::regex(":"), "");
    return stoull(hex, 0, 16);
  } else {
    return 0;
  }
} 
int main()
{
  string iface = "eth0";
  printf("%s: mac=%016llX\n", iface.c_str(), getIFMAC(iface));
}

I don't know why anyone told you that catching runtime exceptions was bad.

Use valueOf and catching IllegalArgumentException is fine for converting/checking a string to an enum.

Try the Apache Commons HttpClient library instead of trying to roll your own: http://hc.apache.org/httpclient-3.x/index.html

From their sample code:

  HttpClient httpclient = new HttpClient();
  httpclient.getHostConfiguration().setProxy("myproxyhost", 8080);

  /* Optional if authentication is required.
  httpclient.getState().setProxyCredentials("my-proxy-realm", " myproxyhost",
   new UsernamePasswordCredentials("my-proxy-username", "my-proxy-password"));
  */

  PostMethod post = new PostMethod("https://someurl");
  NameValuePair[] data = {
     new NameValuePair("user", "joe"),
     new NameValuePair("password", "bloggs")
  };
  post.setRequestBody(data);
  // execute method and handle any error responses.
  // ...
  InputStream in = post.getResponseBodyAsStream();
  // handle response.


  /* Example for a GET reqeust
  GetMethod httpget = new GetMethod("https://someurl");
  try { 
    httpclient.executeMethod(httpget);
    System.out.println(httpget.getStatusLine());
  } finally {
    httpget.releaseConnection();
  }
  */

It looks like the phoneGap plugin will allow you to get the device's uid.

http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html#device.uuid

Update: This is dependent on running native code. We used this solution writing javascript that was being compiled to native code for a native phone application we were creating.

In a SQL Server trigger you have available two psdeuotables called inserted and deleted. These contain the old and new values of the record.

So within the trigger (you can look up the create trigger parts easily) you would do something like this:

Insert table2 (user_id, user_name)
select user_id, user_name from inserted i
left join table2 t on i.user_id = t.userid
where t.user_id is null

When writing triggers remember they act once on the whole batch of information, they do not process row-by-row. So account for multiple row inserts in your code.

I've had this problem before too and I think I found the answer.

If you are using a button to run the macro, it is likely linked to a different macro, perhaps a save as version of what you are currently working in and you might not even realize it. Try running the macro directly from VBA (F5) instead of running it with the button. My guess is that will work. You just have to reassign the macro on the button to the one you actually want to run.

You can pass via GET. So if you want to pass the value foobar from PageA.php to PageB.php, call it as PageB.php?value=foobar.

In PageB.php, you can access it this way:

$value = $_GET['value'];

All of the answers seem to be missing the fact that you may need to complete some portion of work in coordinated fashion during graceful shutdown (for example, in an enterprise application).

@PreDestroy allows you to execute shutdown code in the individual beans. Something more sophisticated would look like this:

@Component
public class ApplicationShutdown implements ApplicationListener<ContextClosedEvent> {
     @Autowired ... //various components and services

     @Override
     public void onApplicationEvent(ContextClosedEvent event) {
         service1.changeHeartBeatMessage(); // allows loadbalancers & clusters to prepare for the impending shutdown
         service2.deregisterQueueListeners();
         service3.finishProcessingTasksAtHand();
         service2.reportFailedTasks();
         service4.gracefullyShutdownNativeSystemProcessesThatMayHaveBeenLaunched(); 
         service1.eventLogGracefulShutdownComplete();
     }
}

i want to post my solution here which was done AngularJS, ASP.NET MVC. The code illustrates how to download file with authentication.

WebApi method along with helper class:

[RoutePrefix("filess")]
class FileController: ApiController
{
    [HttpGet]
    [Route("download-file")]
    [Authorize(Roles = "admin")]
    public HttpResponseMessage DownloadDocument([FromUri] int fileId)
    {
        var file = "someFile.docx"// asking storage service to get file path with id
        return Request.ReturnFile(file);
    }
}

static class DownloadFIleFromServerHelper
{
    public static HttpResponseMessage ReturnFile(this HttpRequestMessage request, string file)
    {
        var result = request.CreateResponse(HttpStatusCode.OK);

        result.Content = new StreamContent(new FileStream(file, FileMode.Open, FileAccess.Read));
        result.Content.Headers.Add("x-filename", Path.GetFileName(file)); // letters of header names will be lowercased anyway in JS.
        result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
        result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
        {
            FileName = Path.GetFileName(file)
        };

        return result;
    }
}

Web.config file changes to allow sending file name in custom header.

<configuration>
    <system.webServer>
        <httpProtocol>
            <customHeaders>
                <add name="Access-Control-Allow-Methods" value="POST,GET,PUT,PATCH,DELETE,OPTIONS" />
                <add name="Access-Control-Allow-Headers" value="Authorization,Content-Type,x-filename" />
                <add name="Access-Control-Expose-Headers" value="Authorization,Content-Type,x-filename" />
                <add name="Access-Control-Allow-Origin" value="*" />

Angular JS Service Part:

function proposalService($http, $cookies, config, FileSaver) {
        return {
                downloadDocument: downloadDocument
        };

    function downloadFile(documentId, errorCallback) {
    $http({
        url: config.apiUrl + "files/download-file?documentId=" + documentId,
        method: "GET",
        headers: {
            "Content-type": "application/json; charset=utf-8",
            "Authorization": "Bearer " + $cookies.get("api_key")
        },
        responseType: "arraybuffer"  
        })
    .success( function(data, status, headers) {
        var filename = headers()['x-filename'];

        var blob = new Blob([data], { type: "application/octet-binary" });
        FileSaver.saveAs(blob, filename);
    })
    .error(function(data, status) {
        console.log("Request failed with status: " + status);
        errorCallback(data, status);
    });
};
};

Module dependency for FileUpload: angular-file-download (gulp install angular-file-download --save). Registration looks like below.

var app = angular.module('cool',
[
    ...
    require('angular-file-saver'),
])
. // other staff.

You can use pure Python to do it:

import json
list = [1, 2, (3, 4)] # Note that the 3rd element is a tuple (3, 4)
json.dumps(list) # '[1, 2, [3, 4]]'

I think there may be problem that you haven't added click listener for ok positive button.

dlgAlert.setPositiveButton("Ok",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
          //dismiss the dialog  
        }
    });

I'll try to answer all your questions by addressing the larger question: How can I sync data between a webserver and an android app?

Syncing data between your webserver and an android app requires a couple of different components on your android device.

Persistent Storage:

This is how your phone actually stores the data it receives from the webserver. One possible method for accomplishing this is writing your own custom ContentProvider backed by a Sqlite database. A decent tutorial for a content provider can be found here: http://thinkandroid.wordpress.com/2010/01/13/writing-your-own-contentprovider/

A ContentProvider defines a consistent interface to interact with your stored data. It could also allow other applications to interact with your data if you wanted. Behind your ContentProvider could be a Sqlite database, a Cache, or any arbitrary storage mechanism.

While I would certainly recommend using a ContentProvider with a Sqlite database you could use any java based storage mechanism you wanted.

Data Interchange Format:

This is the format you use to send the data between your webserver and your android app. The two most popular formats these days are XML and JSON. When choosing your format, you should think about what sort of serialization libraries are available. I know off-hand that there's a fantastic library for json serialization called gson: https://github.com/google/gson, although I'm sure similar libraries exist for XML.

Synchronization Service

You'll want some sort of asynchronous task which can get new data from your server and refresh the mobile content to reflect the content of the server. You'll also want to notify the server whenever you make local changes to content and want to reflect those changes. Android provides the SyncAdapter pattern as a way to easily solve this pattern. You'll need to register user accounts, and then Android will perform lots of magic for you, and allow you to automatically sync. Here's a good tutorial: http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1/

As for how you identify if the records are the same, typically you'll create items with a unique id which you store both on the android device and the server. You can use that to make sure you're referring to the same reference. Furthermore, you can store column attributes like "updated_at" to make sure that you're always getting the freshest data, or you don't accidentally write over newly written data.

Two ways are shorter and easy:

let arr = [2, 6, 1, 0]

Way 1:

let max = Math.max.apply(null, arr)

Way 2:

let max = arr.reduce(function(a, b) {
    return Math.max(a, b);
});

According to my understanding, Application.Current.Shutdown() also has its drawback.

If you want to show a confirmation window to let users confirm on quit or not, Application.Current.Shutdown() is irreversible.

I'm Sure you are not looking for a closure solution, try this for a more compact solution

 try{
    DB::beginTransaction();

    /*
     * Your DB code
     * */

    DB::commit();
}catch(\Exception $e){
    DB::rollback();
}

How about calling a function from within your callback instead of returning a value in sync_call()?

function sync_call(input) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) {
        value = result;
        use_value(value);
    } );
}

export VAR=value will set VAR to value. Enclose it in single quotes if you want spaces, like export VAR='my val'. If you want the variable to be interpolated, use double quotes, like export VAR="$MY_OTHER_VAR".

I didn't have the same problem but similar. Below code solves your problem too, of course if you don't mind performance issue. Before implement that kind of solution to your system I recommend you to redesign your structure if you can. Sending variable structure response is over-engineering. I believe a response structure represents a contract between a request and resource and it should't be depend requests.(you can make un-wanted fields null, I do). In some cases we have to implement this design, if you believe you are in that cases here is the play link and code I use.

type User2 struct {
    ID       int    `groups:"id" json:"id,omitempty"`
    Username string `groups:"username" json:"username,omitempty"`
    Nickname string `groups:"nickname" json:"nickname,omitempty"`
}

type User struct {
    ID       int    `groups:"private,public" json:"id,omitempty"`
    Username string `groups:"private" json:"username,omitempty"`
    Nickname string `groups:"public" json:"nickname,omitempty"`
}

var (
    tagName = "groups"
)

//OmitFields sets fields nil by checking their tag group value and access control tags(acTags)
func OmitFields(obj interface{}, acTags []string) {
    //nilV := reflect.Value{}
    sv := reflect.ValueOf(obj).Elem()
    st := sv.Type()
    if sv.Kind() == reflect.Struct {
        for i := 0; i < st.NumField(); i++ {
            fieldVal := sv.Field(i)
            if fieldVal.CanSet() {
                tagStr := st.Field(i).Tag.Get(tagName)
                if len(tagStr) == 0 {
                    continue
                }
                tagList := strings.Split(strings.Replace(tagStr, " ", "", -1), ",")
                //fmt.Println(tagList)
                // ContainsCommonItem checks whether there is at least one common item in arrays
                if !ContainsCommonItem(tagList, acTags) {
                    fieldVal.Set(reflect.Zero(fieldVal.Type()))
                }
            }
        }
    }
}

//ContainsCommonItem checks if arrays have at least one equal item
func ContainsCommonItem(arr1 []string, arr2 []string) bool {
    for i := 0; i < len(arr1); i++ {
        for j := 0; j < len(arr2); j++ {
            if arr1[i] == arr2[j] {
                return true
            }
        }
    }
    return false
}
func main() {
    u := User{ID: 1, Username: "very secret", Nickname: "hinzir"}
    //assume authenticated user doesn't has permission to access private fields
    OmitFields(&u, []string{"public"}) 
    bytes, _ := json.Marshal(&u)
    fmt.Println(string(bytes))


    u2 := User2{ID: 1, Username: "very secret", Nickname: "hinzir"}
    //you want to filter fields by field names
    OmitFields(&u2, []string{"id", "nickname"}) 
    bytes, _ = json.Marshal(&u2)
    fmt.Println(string(bytes))

}

SSMS only allows unlimited data for XML data. This is not the default and needs to be set in the options.

One trick which might work in quite limited circumstances is simply naming the column in a special manner as below so it gets treated as XML data.

DECLARE @S varchar(max) = 'A'

SET @S =  REPLICATE(@S,100000) + 'B' 

SELECT @S as [XML_F52E2B61-18A1-11d1-B105-00805F49916B]

In SSMS (at least versions 2012 to current of 18.3) this displays the results as below

Clicking on it opens the full results in the XML viewer. Scrolling to the right shows the last character of B is preserved,

However this does have some significant problems. Adding extra columns to the query breaks the effect and extra rows all become concatenated with the first one. Finally if the string contains characters such as < opening the XML viewer fails with a parsing error.

A more robust way of doing this that avoids issues of SQL Server converting < to < etc or failing due to these characters is below (credit Adam Machanic here).

DECLARE @S varchar(max)

SELECT @S = ''

SELECT @S = @S + '
' + OBJECT_DEFINITION(OBJECT_ID) FROM SYS.PROCEDURES

SELECT @S AS [processing-instruction(x)] FOR XML PATH('')

However, empty($error) still returns true, even though nothing is set.

That's not how empty() works. According to the manual, it will return true on an empty array only. Anything else wouldn't make sense.

Actually Java doesn't have multi-dimensional array in mathematical sense. What Java has is just array of arrays, an array where each element is also an array. That is why the absolute requirement to initialize it is the size of the first dimension. If the rest are specified then it will create an array populated with default value.

int[][]   ar  = new int[2][];
int[][][] ar  = new int[2][][];
int[][]   ar  = new int[2][2]; // 2x2 array with zeros

It also gives us a quirk. The size of the sub-array cannot be changed by adding more elements, but we can do so by assigning a new array of arbitrary size.

int[][]   ar  = new int[2][2];
ar[1][3] = 10; // index out of bound
ar[1]    = new int[] {1,2,3,4,5,6}; // works

Found the solution myself in the end. The problem was not with the LinearLayout, but with the ScrollView (seems weird, considering the fact that the ScrollView was expanding, while the LinearLayout wasn't).

The solution was to use android:fillViewport="true" on the ScrollView.

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

You can use prettytable to render the table as text. The trick is to convert the data_frame to an in-memory csv file and have prettytable read it. Here's the code:

from StringIO import StringIO
import prettytable    

output = StringIO()
data_frame.to_csv(output)
output.seek(0)
pt = prettytable.from_csv(output)
print pt

If you have >100 images that you want to have drop shadows for, I would suggest using the command-line program ImageMagick. With this, you can apply shaped drop shadows to 100 images just by typing one command! For example:

for i in "*.png"; do convert $i '(' +clone -background black -shadow 80x3+3+3 ')' +swap -background none -layers merge +repage "shadow/$i"; done

The above (shell) command takes each .png file in the current directory, applies a drop shadow, and saves the result in the shadow/ directory. If you don't like the drop shadows generated, you can tweak the parameters a lot; start by looking at the documentation for shadows, and the general usage instructions have a lot of cool examples of things that can be done to images.

If you change your mind in the future about the look of the drop shadows - it's just one command to generate new images with different parameters :-)

mysqlclient is a fork of MySQLdb and can serve as a drop-in replacement with Python 3.4 support. If you have trouble building it on Windows, you can download it from Christoph Gohlke's Unofficial Windows Binaries for Python Extension Packages

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            ContextCompat.startForegroundService(context, Intent(context, YourServiceClass::class.java))
        } else {
            context.startService(Intent(context, YourServiceClass::class.java))
        }
    }
}

3) Declare in Manifest file like this under application tag

<receiver android:name=".utils.BootCompletedReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        </intent-filter>
    </receiver>

For some kind of reason my NULL values where of data length 8. That is why none of the abovementioned seemed to work. If you encounter the same problem, use the following code:

--Check the length of your NULL values
SELECT DATALENGTH(COLUMN) as length_column
FROM your_table

--Filter the length of your NULL values (8 is used as example)
WHERE DATALENGTH(COLUMN) > 8

Python lists have no built-in pre-allocation. If you really need to make a list, and need to avoid the overhead of appending (and you should verify that you do), you can do this:

l = [None] * 1000 # Make a list of 1000 None's
for i in xrange(1000):
    # baz
    l[i] = bar
    # qux

Perhaps you could avoid the list by using a generator instead:

def my_things():
    while foo:
        #baz
        yield bar
        #qux

for thing in my_things():
    # do something with thing

This way, the list isn't every stored all in memory at all, merely generated as needed.

I hate to answer my own questions, but I did finally find a solution that actually works (using socket communication between services may fix the problem, but it creates even more problems). Since our database is legacy, it merely required Microsoft.ACE.OLEDB.12.0 in the connection string. It turns out that this was also included in Office 2007 (and MSDE 2007), where there is only a 32-bit version available. So, instead of installing MSDE 2010 32-bit, we install MSDE 2007, and it works just fine. Other applications can then install 64-bit MSDE 2010 (or 64-bit Office 2010), and it does not conflict with our application.

Thus far, it appears this is an acceptable solution for all Windows OS environments.

Using StringUtils from commons lang

A null source string will return null. An empty ("") source string will return the empty string. A null remove string will return the source string. An empty ("") remove string will return the source string.

String str = StringUtils.remove("Test remove", "remove");
System.out.println(str);
//result will be "Test"

Another option would be to just use the excellent corrr package https://github.com/drsimonj/corrr and do

require(corrr)
require(dplyr)

myData %>% 
   select(x,y,z) %>%  # or do negative or range selections here
   correlate() %>%
   rearrange() %>%  # rearrange by correlations
   shave() # Shave off the upper triangle for a cleaner result

Steps 3 and 4 are entirely optional and are just included to demonstrate the usefulness of the package.

It is working fine with me.

I have the following HTML:

<div>
    <select id="select1">
        <option value="1">test1</option>
        <option value="2" selected="selected">test2</option>
        <option value="3">test3</option>
    </select>
    <br/>
    <button onClick="GetSelectedItem('select1');">Get Selected Item</button>
</div>

And the following JavaScript:

function GetSelectedItem(el)
{
    var e = document.getElementById(el);
    var strSel = "The Value is: " + e.options[e.selectedIndex].value + " and text is: " + e.options[e.selectedIndex].text;
    alert(strSel);
}

See that you are using the right id. In case you are using it with ASP.NET, the id changes when rendered.

I had the same problem, and my solution was to eliminate the line

android:screenOrientation="portrait"

and then add this in the activity:

if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

Just close the Project you want to add , then drag and drop the file .

You don't need an index match formula. You can use this array formula. You have to press CTL + SHIFT + ENTER after you enter the formula.

=MAX(IF((A1:A6=A10)*(B1:B6=B10),C1:F6))

SNAPSHOT

I use lists to filter dataframes by whether or not they have a value %in% a list.

I had been manually creating lists by exporting a 1 column dataframe to Excel where I would add " ", around each element, before pasting into R: list <- c("el1", "el2", ...) which was usually followed by FilteredData <- subset(Data, Column %in% list).

After searching stackoverflow and not finding an intuitive way to convert a 1 column dataframe into a list, I am now posting my first ever stackoverflow contribution:

# assuming you have a 1 column dataframe called "df"
list <- c()
for(i in 1:nrow(df)){
  list <- append(list, df[i,1])
}
View(list)
# This list is not a dataframe, it is a list of values
# You can filter a dataframe using "subset([Data], [Column] %in% list")

echo 'hollow world' . PHP_EOL;

Use the constant PHP_EOL then it is OS independent too.

The NVARCHAR2 datatype was introduced by Oracle for databases that want to use Unicode for some columns while keeping another character set for the rest of the database (which uses VARCHAR2). The NVARCHAR2 is a Unicode-only datatype.

One reason you may want to use NVARCHAR2 might be that your DB uses a non-Unicode character set and you still want to be able to store Unicode data for some columns without changing the primary character set. Another reason might be that you want to use two Unicode character set (AL32UTF8 for data that comes mostly from western Europe, AL16UTF16 for data that comes mostly from Asia for example) because different character sets won't store the same data equally efficiently.

Both columns in your example (Unicode VARCHAR2(10 CHAR) and NVARCHAR2(10)) would be able to store the same data, however the byte storage will be different. Some strings may be stored more efficiently in one or the other.

Note also that some features won't work with NVARCHAR2, see this SO question:

• Oracle Text will not work with NVARCHAR2. What else might be unavailable?

We're happy with a custom hook we call useCounterKey. It just sets up a counterKey, or a key that counts up from zero. The function it returns resets the key (i.e. increment). (I believe this is the most idiomatic way in React to reset a component - just bump the key.)

However this hook also works in any situation where you want to send a one-time message to the client to do something. E.g. we use it to focus a control in the child on a certain parent event - it just autofocuses anytime the key is updated. (If more props are needed they could be set prior to resetting the key so they're available when the event happens.)

This method has a bit of a learning curve b/c it's not as straightforward as a typical event handler, but it seems the most idiomatic way to handle this in React that we've found (since keys already function this way). Def open to feedback on this method but it is working well!

// Main helper hook:
export function useCounterKey() {
  const [key, setKey] = useState(0);
  return [key, () => setKey(prev => prev + 1)] as const;
}

Sample usages:

// Sample 1 - normal React, just reset a control by changing Key on demand
function Sample1() {
  const [inputLineCounterKey, resetInputLine] = useCounterKey();

  return <>
    <InputLine key={inputLineCounterKey} />
    <button onClick={() => resetInputLine()} />
  <>;
}

// Second sample - anytime the counterKey is incremented, child calls focus() on the input
function Sample2() {
  const [amountFocusCounterKey, focusAmountInput] = useCounterKey();

  // ... call focusAmountInput in some hook or event handler as needed

  return <WorkoutAmountInput focusCounterKey={amountFocusCounterKey} />
}

function WorkoutAmountInput(props) {
  useEffect(() => {
    if (counterKey > 0) {
      // Don't focus initially
      focusAmount();
    }
  }, [counterKey]);

  // ...
}

(Credit to Kent Dodds for the counterKey concept.)

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;

For more details refer to: http://www.postgresql.org/docs/9.2/static/sql-copy.html

It depends upon the context. Some possible contexts in HTML:

• document body
• inside common attributes
• inside script tags
• inside style tags
• several more!

See OWASP's Cross Site Scripting Prevention Cheat Sheet, especially the "Why Can't I Just HTML Entity Encode Untrusted Data?" and "XSS Prevention Rules" sections. However, it's best to read the whole document.

export default is used to export a single class, function or primitive from a script file.

The export can also be written as

export default function SafeString(string) {
  this.string = string;
}

SafeString.prototype.toString = function() {
  return "" + this.string;
};

This is used to import this function in another script file

Say in app.js, you can

import SafeString from './handlebars/safe-string';

A little about export

As the name says, it's used to export functions, objects, classes or expressions from script files or modules

Utiliites.js

export function cube(x) {
  return x * x * x;
}
export const foo = Math.PI + Math.SQRT2;

This can be imported and used as

App.js

import { cube, foo } from 'Utilities';
console.log(cube(3)); // 27
console.log(foo);    // 4.555806215962888

Or

import * as utilities from 'Utilities';
console.log(utilities.cube(3)); // 27
console.log(utilities.foo);    // 4.555806215962888

When export default is used, this is much simpler. Script files just exports one thing. cube.js

export default function cube(x) {
  return x * x * x;
};

and used as App.js

import Cube from 'cube';
console.log(Cube(3)); // 27

Shameless plug of a library that I wrote the solve this.

The above will take the contents of /path/to/include.html and replace the div with it.

I am amazed how I've not been able to find a clear example of how to authenticate an user right from the login screen down to using the Authorize attribute over my ApiController methods after several hours of Googling.

That's because you are getting confused about these two concepts:

• Authentication is the mechanism whereby systems may securely identify their users. Authentication systems provide an answers to the questions:

  • Who is the user?
  • Is the user really who he/she represents himself to be?

• Authorization is the mechanism by which a system determines what level of access a particular authenticated user should have to secured resources controlled by the system. For example, a database management system might be designed so as to provide certain specified individuals with the ability to retrieve information from a database but not the ability to change data stored in the datbase, while giving other individuals the ability to change data. Authorization systems provide answers to the questions:

  • Is user X authorized to access resource R?
  • Is user X authorized to perform operation P?
  • Is user X authorized to perform operation P on resource R?

The Authorize attribute in MVC is used to apply access rules, for example:

 [System.Web.Http.Authorize(Roles = "Admin, Super User")]
 public ActionResult AdministratorsOnly()
 {
     return View();
 }

The above rule will allow only users in the Admin and Super User roles to access the method

These rules can also be set in the web.config file, using the location element. Example:

  <location path="Home/AdministratorsOnly">
    <system.web>
      <authorization>
        <allow roles="Administrators"/>
        <deny users="*"/>
      </authorization>
    </system.web>
  </location>

However, before those authorization rules are executed, you have to be authenticated to the current web site.

Even though these explain how to handle unauthorized requests, these do not demonstrate clearly something like a LoginController or something like that to ask for user credentials and validate them.

From here, we could split the problem in two:

• Authenticate users when consuming the Web API services within the same Web application

  This would be the simplest approach, because you would rely on the Authentication in ASP.Net

  This is a simple example:

  Web.config

  <authentication mode="Forms">
    <forms
      protection="All"
      slidingExpiration="true"
      loginUrl="account/login"
      cookieless="UseCookies"
      enableCrossAppRedirects="false"
      name="cookieName"
    />
  </authentication>
  

  Users will be redirected to the account/login route, there you would render custom controls to ask for user credentials and then you would set the authentication cookie using:

      if (ModelState.IsValid)
      {
          if (Membership.ValidateUser(model.UserName, model.Password))
          {
              FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
              return RedirectToAction("Index", "Home");
          }
          else
          {
              ModelState.AddModelError("", "The user name or password provided is incorrect.");
          }
      }
  
      // If we got this far, something failed, redisplay form
      return View(model);
  

• Cross - platform authentication

  This case would be when you are only exposing Web API services within the Web application therefore, you would have another client consuming the services, the client could be another Web application or any .Net application (Win Forms, WPF, console, Windows service, etc)

  For example assume that you will be consuming the Web API service from another web application on the same network domain (within an intranet), in this case you could rely on the Windows authentication provided by ASP.Net.

  <authentication mode="Windows" />
  

  If your services are exposed on the Internet, then you would need to pass the authenticated tokens to each Web API service.

  For more info, take a loot to the following articles:

  • http://stevescodingblog.co.uk/basic-authentication-with-asp-net-webapi/

If increasing max_allowed_packet doesn't help.

I was getting the same error as you when importing a .sql file into my database via Sequel Pro.

The error still persisted after upping the max_allowed_packet to 512M so I ran the import in the command line instead with:

mysql --verbose -u root -p DatabaseName < MySQL.sql

It gave the following error:

ASCII '\0' appeared in the statement, but this is not allowed unless option --binary-mode is enabled

I found a couple helpful StackOverflow questions:

• Enable binary mode while restoring a Database from an SQL dump
• Mysql ERROR: ASCII '\0' while importing sql file on linux server

In my case, my .sql file was a little corrupt or something. The MySQL dump we get comes in two zip files that need to be concatenated together and then unzipped. I think the unzipping was interrupted initially, leaving the file with some odd characters and encodings. Getting a fresh MySQL dump and unzipping it properly worked for me.

Just wanted to add this here in case others find that increasing the max_allowed_packet variable was not helping.

expanding on @leaf 's answer, here's one that can take multiple characters:

var trim = function (s, t) {
  var tr, sr
  tr = t.split('').map(e => `\\\\${e}`).join('')
  sr = s.replace(new RegExp(`^[${tr}]+|[${tr}]+$`, 'g'), '')
  return sr
}

use return in the if condition will returns you out from the function, so that you can use return to break the the if condition.

I run some tests to see if links on my site are valid - alerts me to when third parties change their links. I was having an issue with a site that had a poorly configured certificate that meant that php's get_headers didn't work.

SO, I read that curl was faster and decided to give that a go. then i had an issue with linkedin which gave me a 999 error, which turned out to be a user agent issue.

I didn't care if the certificate was not valid for this test, and i didn't care if the response was a re-direct.

Then I figured use get_headers anyway if curl was failing....

Give it a go....

/**
 * returns true/false if the $url is present.
 *
 * @param string $url assumes this is a valid url.
 *
 * @return bool
 */
private function url_exists (string $url): bool
{
  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_NOBODY, TRUE);             // this does a head request to make it faster.
  curl_setopt($ch, CURLOPT_HEADER, TRUE);             // just the headers
  curl_setopt($ch, CURLOPT_SSL_VERIFYSTATUS, FALSE);  // turn off that pesky ssl stuff - some sys admins can't get it right.
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  // set a real user agent to stop linkedin getting upset.
  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36');
  curl_exec($ch);
  $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  if (($http_code >= HTTP_OK && $http_code < HTTP_BAD_REQUEST) || $http_code === 999)
  {
    curl_close($ch);
    return TRUE;
  }
  $error = curl_error($ch); // used for debugging.
  curl_close($ch);
  // just try the get_headers - it might work!
  stream_context_set_default(array('http' => array('method' => 'HEAD')));
  $file_headers = @get_headers($url);
  if ($file_headers)
  {
    $response_code = substr($file_headers[0], 9, 3);
    return $response_code >= 200 && $response_code < 400;
  }
  return FALSE;
}

You may already find your answer because it was some time ago you asked. But I tried to do something similar when coding ror. I wanted to run "rails server" in a new cmd window so I don't have to open a new cmd and then find my path again.

What I found out was to use the K switch like this:

start cmd /k echo Hello, World!

start before "cmd" will open the application in a new window and "/K" will execute "echo Hello, World!" after the new cmd is up.

You can also use the /C switch for something similar.

start cmd /C pause

This will then execute "pause" but close the window when the command is done. In this case after you pressed a button. I found this useful for "rails server", then when I shutdown my dev server I don't have to close the window after.

Use the following in your batch file:

start cmd.exe /c "more-batch-commands-here"

or

start cmd.exe /k "more-batch-commands-here"

/c Carries out the command specified by string and then terminates

/k Carries out the command specified by string but remains

The /c and /k options controls what happens once your command finishes running. With /c the terminal window will close automatically, leaving your desktop clean. With /k the terminal window will remain open. It's a good option if you want to run more commands manually afterwards.

Consult the cmd.exe documentation using cmd /? for more details.

Escaping Commands with White Spaces

The proper formatting of the command string becomes more complicated when using arguments with spaces. See the examples below. Note the nested double quotes in some examples.

Examples:

Run a program and pass a filename parameter:
CMD /c write.exe c:\docs\sample.txt

Run a program and pass a filename which contains whitespace:
CMD /c write.exe "c:\sample documents\sample.txt"

Spaces in program path:
CMD /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in program path + parameters:
CMD /c ""c:\Program Files\demo.cmd"" Parameter1 Param2
CMD /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch demo1 and demo2:
CMD /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

You need to define height of ul or your div and set overflow equals to auto as below:

<ul style="width: 300px; height: 200px; overflow: auto">
  <li>text</li>
  <li>text</li>

genrsa has been replaced by genpkey & when run manually in a terminal it will prompt for a password:

openssl genpkey -aes-256-cbc -algorithm RSA -out /etc/ssl/private/key.pem -pkeyopt rsa_keygen_bits:4096

However when run from a script the command will not ask for a password so to avoid the password being viewable as a process use a function in a shell script:

get_passwd() {
    local passwd=
    echo -ne "Enter passwd for private key: ? "; read -s passwd
    openssl genpkey -aes-256-cbc -pass pass:$passwd -algorithm RSA -out $PRIV_KEY -pkeyopt rsa_keygen_bits:$PRIV_KEYSIZE
}

Use the keyword next. If you do not want to continue to the next item, use break.

When next is used within a block, it causes the block to exit immediately, returning control to the iterator method, which may then begin a new iteration by invoking the block again:

f.each do |line|              # Iterate over the lines in file f
  next if line[0,1] == "#"    # If this line is a comment, go to the next
  puts eval(line)
end

When used in a block, break transfers control out of the block, out of the iterator that invoked the block, and to the first expression following the invocation of the iterator:

f.each do |line|             # Iterate over the lines in file f
  break if line == "quit\n"  # If this break statement is executed...
  puts eval(line)
end
puts "Good bye"              # ...then control is transferred here

And finally, the usage of return in a block:

return always causes the enclosing method to return, regardless of how deeply nested within blocks it is (except in the case of lambdas):

def find(array, target)
  array.each_with_index do |element,index|
    return index if (element == target)  # return from find
  end
  nil  # If we didn't find the element, return nil
end

I will side with nategood's answer as it is complete and it seemed to have please your needs. Though, I would like to add a comment on identifying multiple (1 or more) resource that way:

http://our.api.com/Product/101404,7267261

In doing so, you:

Complexify the clients by forcing them to interpret your response as an array, which to me is counter intuitive if I make the following request: http://our.api.com/Product/101404

Create redundant APIs with one API for getting all products and the one above for getting 1 or many. Since you shouldn't show more than 1 page of details to a user for the sake of UX, I believe having more than 1 ID would be useless and purely used for filtering the products.

It might not be that problematic, but you will either have to handle this yourself server side by returning a single entity (by verifying if your response contains one or more) or let clients manage it.

Example

I want to order a book from Amazing. I know exactly which book it is and I see it in the listing when navigating for Horror books:

1. 10 000 amazing lines, 0 amazing test
2. The return of the amazing monster
3. Let's duplicate amazing code
4. The amazing beginning of the end

After selecting the second book, I am redirected to a page detailing the book part of a list:

--------------------------------------------
Book #1
--------------------------------------------
    Title: The return of the amazing monster
    Summary:
    Pages:
    Publisher:
--------------------------------------------

Or in a page giving me the full details of that book only?

---------------------------------
The return of the amazing monster
---------------------------------
Summary:
Pages:
Publisher:
---------------------------------

My Opinion

I would suggest using the ID in the path variable when unicity is guarantied when getting this resource's details. For example, the APIs below suggest multiple ways to get the details for a specific resource (assuming a product has a unique ID and a spec for that product has a unique name and you can navigate top down):

/products/{id}
/products/{id}/specs/{name}

The moment you need more than 1 resource, I would suggest filtering from a larger collection. For the same example:

/products?ids=

Of course, this is my opinion as it is not imposed.

only start listner then u can connect with database. command run on editor:

lsnrctl start

its work fine.

Use some regex like [0-9] or \d:

$words = preg_replace('/\d+/', '', $words );

You might want to read the preg_replace() documentation as this is directly shown there.

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

The best way is to simply use Convert.ToInt32. It is fast and also rounds correctly.

Why make it more complicated?

Use time

Let's say you have the initial dates as strings like these:
date1 = "31/12/2015"
date2 = "01/01/2016"

You can do the following:
newdate1 = time.strptime(date1, "%d/%m/%Y") and newdate2 = time.strptime(date2, "%d/%m/%Y") to convert them to python's date format. Then, the comparison is obvious:

newdate1 > newdate2 will return False
newdate1 < newdate2 will return True

Every SQL reference I can find says the "any single character" wildcard is the underscore (_), not the question mark (?). That simplifies things a bit, since the underscore is not a regex metacharacter. However, you still can't use Pattern.quote() for the reason given by mmyers. I've got another method here for escaping regexes when I might want to edit them afterward. With that out of the way, the like() method becomes pretty simple:

public static boolean like(final String str, final String expr)
{
  String regex = quotemeta(expr);
  regex = regex.replace("_", ".").replace("%", ".*?");
  Pattern p = Pattern.compile(regex,
      Pattern.CASE_INSENSITIVE | Pattern.DOTALL);
  return p.matcher(str).matches();
}

public static String quotemeta(String s)
{
  if (s == null)
  {
    throw new IllegalArgumentException("String cannot be null");
  }

  int len = s.length();
  if (len == 0)
  {
    return "";
  }

  StringBuilder sb = new StringBuilder(len * 2);
  for (int i = 0; i < len; i++)
  {
    char c = s.charAt(i);
    if ("[](){}.*+?$^|#\\".indexOf(c) != -1)
    {
      sb.append("\\");
    }
    sb.append(c);
  }
  return sb.toString();
}

If you really want to use ? for the wildcard, your best bet would be to remove it from the list of metacharacters in the quotemeta() method. Replacing its escaped form -- replace("\\?", ".") -- wouldn't be safe because there might be backslashes in the original expression.

And that brings us to the real problems: most SQL flavors seem to support character classes in the forms [a-z] and [^j-m] or [!j-m], and they all provide a way to escape wildcard characters. The latter is usually done by means of an ESCAPE keyword, which lets you define a different escape character every time. As you can imagine, this complicates things quite a bit. Converting to a regex is probably still the best option, but parsing the original expression will be much harder--in fact, the first thing you would have to do is formalize the syntax of the LIKE-like expressions themselves.

I tried many ways mentioned here, especially the preference - editor - general - code completion - show documentation popup in.. isn't working in version 2019.2.2

Finally, i am just using F1 while caret is on the type/method and it displays the documentation nicely. This is not ideal but helpful.

You might be better off using a ListView with a CursorAdapter (or SimpleCursorAdapter).

These are built to show rows from a sqlite database and allow refreshing with minimal programming on your part.

Edit - here is a tutorial involving SimpleCursorAdapter and ListView including sample code.

Did you try putting all your jars directly in the WEB-INF/lib dir instead of sub-dirs of that?

No WEB-INF/lib/spring/org.springframework.aop-3.0.0.RELEASE.jar, just WEB-INF/lib/org.springframework.aop-3.0.0.RELEASE.jar

Same with the rest of the jars.

So much simpler: look at this

B2: 23:00
C2:  1:37
D2: = C2 - B2 + ( B2 > C2 )

Why it works, time is a fraction of a day, the comparison B2>C2 returns True (1) or False (0), if true 1 day (24 hours) is added. http://www.excelforum.com/excel-general/471757-calculating-time-difference-over-midnight.html

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

Set it within button instead of div if you don't care about its little visual 3D effect.

I had the same problem. I eventually figured it out by inspecting the element and the element I thought I had selected was different element. When I did that I found there was a hidden element that had z-index of 9999, once I fixed that my problem went away.

Simply: It's a warning by which the compiler indicates that it cannot ensure type safety.

JPA service method for example:

@SuppressWarnings("unchecked")
public List<User> findAllUsers(){
    Query query = entitymanager.createQuery("SELECT u FROM User u");
    return (List<User>)query.getResultList();
}

If I didn'n anotate the @SuppressWarnings("unchecked") here, it would have a problem with line, where I want to return my ResultList.

In shortcut type-safety means: A program is considered type-safe if it compiles without errors and warnings and does not raise any unexpected ClassCastException s at runtime.

I build on http://www.angelikalanger.com/GenericsFAQ/FAQSections/Fundamentals.html

I had to go to bash (from ZSH) first. Then

sudo -H pip install 'requests[security]' --upgrade

fixed the problem.

When using System.Net.WebRequest your application will negotiate with the server to determine the highest TLS version that both your application and the server support, and use this. You can see more details on how this works here:

http://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_handshake

If the server doesn't support TLS it will fallback to SSL, therefore it could potentially fallback to SSL3. You can see all of the versions that .NET 4.5 supports here:

http://msdn.microsoft.com/en-us/library/system.security.authentication.sslprotocols(v=vs.110).aspx

In order to prevent your application being vulnerable to POODLE, you can disable SSL3 on the machine that your application is running on by following this explanation:

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

However, the support for dashed lines depends on the selected terminal:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

Running

set terminal pngcairo dashed
set output 'test.png'
test
set output

gives:

whereas, the postscript terminal shows different dash patterns:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

Version 5.0

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• A new dashtype parameter was introduced:

  To get the predefined dash patterns, use e.g.

  plot x dashtype 2
  

  You can also specify custom dash patterns like

  plot x dashtype (3,5,10,5),\
       2*x dashtype '.-_'
  

• The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

  set for [i=1:8] linetype i dashtype i
  

• The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:

Try to add type of configuration in dependency line. For example:

implementation project(path: ':some_module', **configuration: 'default'**)`

This one is easy. When you start the installation, Anaconda asks "Destination Folder" as below screenshot. If you are not sure where did default installation go, double click setup file and see what anaconda offers as a default location.

This worked for me:

exclude: [/bower_components/, /node_modules/]

module.loaders

A array of automatically applied loaders.

Each item can have these properties:

test: A condition that must be met

exclude: A condition that must not be met

include: A condition that must be met

loader: A string of "!" separated loaders

loaders: A array of loaders as string

A condition can be a RegExp, an absolute path start, or an array of one of these combined with "and".

See http://webpack.github.io/docs/configuration.html#module-loaders

sed -i 's/$/,/g' foo.txt

I do this quite often to add a comma to the end of an output so I can just easily copy and paste it into a Python(or your fav lang) array

import javax.swing.JOptionPane;
import javax.swing.JFrame;

/*Some piece of code*/
frame.addWindowListener(new java.awt.event.WindowAdapter() {
    @Override
    public void windowClosing(java.awt.event.WindowEvent windowEvent) {
        if (JOptionPane.showConfirmDialog(frame, 
            "Are you sure you want to close this window?", "Close Window?", 
            JOptionPane.YES_NO_OPTION,
            JOptionPane.QUESTION_MESSAGE) == JOptionPane.YES_OPTION){
            System.exit(0);
        }
    }
});

If you also want to prevent the window from closing unless the user chooses 'Yes', you can add:

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

Solution with greedy approach in java is as below :

public class CoinChange {
    public static void main(String args[]) {
        int denominations[] = {1, 5, 10, 25};
        System.out.println("Total required coins are " + greeadApproach(53, denominations));
    }

    public static int greeadApproach(int amount, int denominations[]) {
        int cnt[] = new int[denominations.length];
        for (int i = denominations.length-1; amount > 0 && i >= 0; i--) {
            cnt[i] = (amount/denominations[i]);
            amount -= cnt[i] * denominations[i];            
        }
        int noOfCoins = 0;
        for (int cntVal : cnt) {
            noOfCoins+= cntVal;
        }
        return noOfCoins;
    }
}

But this works for single amount. If you want to run it for range, than we have to call it for each amount of range.

MessageBox like others said, or RegisterClientScriptBlock if you want something more arbitrary, but your use case is extremely dubious. Merely displaying exceptions is not something you want to do in production code - you don't want to expose that detail publicly and you do want to record it with proper logging privately.

You do it exactly as you showed with this line:

get.setHeader("Content-Type", "application/x-zip");

So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.

Guys, don´t scare the crap out of others (hey! just kidding), but it´s really all a question of equivalences and synonyms:

firstly:

"XAND" doesn´t exist logically, neither does "XNAND", however "XAND" is normally thought-up by a studious but confused initiating logic student.(wow!). It com from the thought that, if there´s a XOR(exclusive OR) it´s logical to exist a "XAND"("exclusive" AND). The rational suggestion would be an "IAND"("inclusive" AND), which isn´t used or recognised as well. So:

 XNOR <=> !XOR <=> EQV

And all this just discribes a unique operator, called the equivalency operator(<=>, EQV) so:

A  |  B  | A <=> B | A XAND B | A XNOR B | A !XOR B | ((NOT(A) AND B)AND(A AND NOT(B)))
---------------------------------------------------------------------------------------
T  |  T  |    T    |     T    |     T    |     T    |                T    
T  |  F  |    F    |     F    |     F    |     F    |                F    
F  |  T  |    F    |     F    |     F    |     F    |                F    
F  |  F  |    T    |     T    |     T    |     T    |                T    

And just a closing comment: The 'X' prefix is only possible if and only if the base operator isn´t unary. So, XNOR <=> NOT XOR <=/=> X NOR.

Peace.

If you want use RegEx in .NET,

Regex rx = new Regex(@"^([\w]+)(\-)*");
var match = rx.Match("thisis-thefirst");
var text = match.Groups[1].Value;
Assert.AreEqual("thisis", text);

Answered by zerkms is the correct method. But, if someone looking to insert more extra column in the table then you can get it from the following:

INSERT INTO action_2_members (`campaign_id`, `mobile`, `email`, `vote`, `vote_date`, `current_time`)
SELECT `campaign_id`, `from_number`, '[email protected]', `received_msg`, `date_received`, 1502309889 FROM `received_txts` WHERE `campaign_id` = '8'

In the above query, there are 2 extra columns named email & current_time.

In Kotlin, I am using a class DoubleButtonDialog.Java with line window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT)) as important one

class DoubleButtonDialog(context: Context) : Dialog(context, R.style.DialogTheme) {

    private var cancelableDialog: Boolean = true
    private var titleDialog: String? = null
    private var messageDialog: String? = null
    private var leftButtonDialog: String = "Yes"
    //    private var rightButtonDialog: String? = null
    private var onClickListenerDialog: OnClickListener? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
        //requestWindowFeature(android.view.Window.FEATURE_NO_TITLE)
        setCancelable(cancelableDialog)
        setContentView(R.layout.dialog_double_button)
//        val btnNegative = findViewById<Button>(R.id.btnNegative)
//        btnNegative.visibility = View.GONE
//        if (rightButtonDialog != null) {
//            btnNegative.visibility = View.VISIBLE
//            btnNegative.text = rightButtonDialog
//            btnNegative.setOnClickListener {
//                dismiss()
//                onClickListenerDialog?.onClickCancel()
//            }
//        }
        val btnPositive = findViewById<Button>(R.id.btnPositive)
        btnPositive.text = leftButtonDialog
        btnPositive.setOnClickListener {
            onClickListenerDialog?.onClick()
            dismiss()
        }
        (findViewById<TextView>(R.id.title)).text = titleDialog
        (findViewById<TextView>(R.id.message)).text = messageDialog
        super.onCreate(savedInstanceState)
    }

    constructor(
        context: Context, cancelableDialog: Boolean, titleDialog: String?,
        messageDialog: String, leftButtonDialog: String, /*rightButtonDialog: String?,*/
        onClickListenerDialog: OnClickListener
    ) : this(context) {
        this.cancelableDialog = cancelableDialog
        this.titleDialog = titleDialog
        this.messageDialog = messageDialog
        this.leftButtonDialog = leftButtonDialog
//        this.rightButtonDialog = rightButtonDialog
        this.onClickListenerDialog = onClickListenerDialog
    }
}


interface OnClickListener {
    //    fun onClickCancel()
    fun onClick()
}

In layout, we can create a dialog_double_button.xml

Short answer

To see the whole file: git show stash@{0}:<filename>

To see the diff: git diff stash@{0}^1 stash@{0} -- <filename>

RewriteBase is only applied to the target of a relative rewrite rule.

• Using RewriteBase like this...

  RewriteBase /folder/
  RewriteRule a\.html b.html
  

• is essentially the same as...

  RewriteRule a\.html /folder/b.html
  

• But when the .htaccess file is inside /folder/ then this also points to the same target:

  RewriteRule a\.html b.html
  

Although the docs imply always using a RewriteBase, Apache usually detects it correctly for paths under the DocumentRoot unless:

• You are using Alias directives

• You are using .htaccess rewrite rules to perform HTTP redirects (rather than just silent rewriting) to relative URLs

In these cases, you may find that you need to specify the RewriteBase.

However, since it's a confusing directive, it's generally better to simply specify absolute (aka 'root relative') URIs in your rewrite targets. Other developers reading your rules will grasp these more easily.

Quoting from Jon Lin's excellent in-depth answer here:

In an htaccess file, mod_rewrite works similar to a <Directory> or <Location> container. and the RewriteBase is used to provide a relative path base.

For example, say you have this folder structure:

DocumentRoot
|-- subdir1
`-- subdir2
    `-- subsubdir

So you can access:

• http://example.com/ (root)
• http://example.com/subdir1 (subdir1)
• http://example.com/subdir2 (subdir2)
• http://example.com/subdir2/subsubdir (subsubdir)

The URI that gets sent through a RewriteRule is relative to the directory containing the htaccess file. So if you have:

RewriteRule ^(.*)$ - 

• In the root htaccess, and the request is /a/b/c/d, then the captured URI ($1) is a/b/c/d.
• If the rule is in subdir2 and the request is /subdir2/e/f/g then the captured URI is e/f/g.
• If the rule is in the subsubdir, and the request is /subdir2/subsubdir/x/y/z, then the captured URI is x/y/z.

The directory that the rule is in has that part stripped off of the URI. The rewrite base has no affect on this, this is simply how per-directory works.

What the rewrite base does do, is provide a URL-path base (not a file-path base) for any relative paths in the rule's target. So say you have this rule:

RewriteRule ^foo$ bar.php [L]

The bar.php is a relative path, as opposed to:

RewriteRule ^foo$ /bar.php [L]

where the /bar.php is an absolute path. The absolute path will always be the "root" (in the directory structure above). That means that regardless of whether the rule is in the "root", "subdir1", "subsubdir", etc. the /bar.php path always maps to http://example.com/bar.php.

But the other rule, with the relative path, it's based on the directory that the rule is in. So if

RewriteRule ^foo$ bar.php [L]

is in the "root" and you go to http://example.com/foo, you get served http://example.com/bar.php. But if that rule is in the "subdir1" directory, and you go to http://example.com/subdir1/foo, you get served http://example.com/subdir1/bar.php. etc. This sometimes works and sometimes doesn't, as the documentation says, it's supposed to be required for relative paths, but most of the time it seems to work. Except when you are redirecting (using the R flag, or implicitly because you have http://host in your rule's target). That means this rule:

RewriteRule ^foo$ bar.php [L,R]

if it's in the "subdir2" directory, and you go to http://example.com/subdir2/foo, mod_rewrite will mistake the relative path as a file-path instead of a URL-path and because of the R flag, you'll end up getting redirected to something like: http://example.com/var/www/localhost/htdocs/subdir1. Which is obviously not what you want.

This is where RewriteBase comes in. The directive tells mod_rewrite what to append to the beginning of every relative path. So if I have:

RewriteBase /blah/
RewriteRule ^foo$ bar.php [L]

in "subsubdir", going to http://example.com/subdir2/subsubdir/foo will actually serve me http://example.com/blah/bar.php. The "bar.php" is added to the end of the base. In practice, this example is usually not what you want, because you can't have multiple bases in the same directory container or htaccess file.

In most cases, it's used like this:

RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]

where those rules would be in the "subdir1" directory and

RewriteBase /subdir2/subsubdir/
RewriteRule ^foo$ bar.php [L]

would be in the "subsubdir" directory.

This partly allows you to make your rules portable, so you can drop them in any directory and only need to change the base instead of a bunch of rules. For example if you had:

RewriteEngine On
RewriteRule ^foo$ /subdir1/bar.php [L]
RewriteRule ^blah1$ /subdir1/blah.php?id=1 [L]
RewriteRule ^blah2$ /subdir1/blah2.php [L]
...

such that going to http://example.com/subdir1/foo will serve http://example.com/subdir1/bar.php etc. And say you decided to move all of those files and rules to the "subsubdir" directory. Instead of changing every instance of /subdir1/ to /subdir2/subsubdir/, you could have just had a base:

RewriteEngine On
RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]
RewriteRule ^blah1$ blah.php?id=1 [L]
RewriteRule ^blah2$ blah2.php [L]
...

And then when you needed to move those files and the rules to another directory, just change the base:

RewriteBase /subdir2/subsubdir/

and that's it.

If you know the exact axis you want, then

pylab.ylim([0,1000])

works as answered previously. But if you want a more flexible axis to fit your exact data, as I did when I found this question, then set axis limit to be the length of your dataset. If your dataset is fft as in the question, then add this after your plot command:

length = (len(fft)) pylab.ylim([0,length])

Just run this: select * from v$version

Make sure to check the phpMyAdmin config file as well! On newer WAMP applications it is set to 128Mb by default. Even if you update php.ini to desired values you still need to update the phpmyadmin.conf!

Sample path: C:\wamp64\alias\phpmyadmin.conf

Or edit through your WAMP icon by: ->Apache -> Alias directories -> phpMyAdmin

If you place your buttons inside a div with class "btn-group" the buttons inside will stretch to the same size as the largest button.

eg:

<div class="btn-group">
  <button type="button" class="btn btn-default">Left</button>
  <button type="button" class="btn btn-default">Middle</button>
  <button type="button" class="btn btn-default">Right</button>
</div>

There is a much easier way!

You can easily create an attached DocumentXaml (or DocumentRTF) property which will allow you to bind the RichTextBox's document. It is used like this, where Autobiography is a string property in your data model:

<TextBox Text="{Binding FirstName}" />
<TextBox Text="{Binding LastName}" />
<RichTextBox local:RichTextBoxHelper.DocumentXaml="{Binding Autobiography}" />

Voila! Fully bindable RichTextBox data!

The implementation of this property is quite simple: When the property is set, load the XAML (or RTF) into a new FlowDocument. When the FlowDocument changes, update the property value.

This code should do the trick:

using System.IO;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
public class RichTextBoxHelper : DependencyObject
{
    public static string GetDocumentXaml(DependencyObject obj)
    {
        return (string)obj.GetValue(DocumentXamlProperty);
    }

    public static void SetDocumentXaml(DependencyObject obj, string value)
    {
        obj.SetValue(DocumentXamlProperty, value);
    }

    public static readonly DependencyProperty DocumentXamlProperty =
        DependencyProperty.RegisterAttached(
            "DocumentXaml",
            typeof(string),
            typeof(RichTextBoxHelper),
            new FrameworkPropertyMetadata
            {
                BindsTwoWayByDefault = true,
                PropertyChangedCallback = (obj, e) =>
                {
                    var richTextBox = (RichTextBox)obj;

                    // Parse the XAML to a document (or use XamlReader.Parse())
                    var xaml = GetDocumentXaml(richTextBox);
                    var doc = new FlowDocument();
                    var range = new TextRange(doc.ContentStart, doc.ContentEnd);

                    range.Load(new MemoryStream(Encoding.UTF8.GetBytes(xaml)),
                          DataFormats.Xaml);

                    // Set the document
                    richTextBox.Document = doc;

                    // When the document changes update the source
                    range.Changed += (obj2, e2) =>
                    {
                        if (richTextBox.Document == doc)
                        {
                            MemoryStream buffer = new MemoryStream();
                            range.Save(buffer, DataFormats.Xaml);
                            SetDocumentXaml(richTextBox,
                                Encoding.UTF8.GetString(buffer.ToArray()));
                        }
                    };
                }
            });
}

The same code could be used for TextFormats.RTF or TextFormats.XamlPackage. For XamlPackage you would have a property of type byte[] instead of string.

The XamlPackage format has several advantages over plain XAML, especially the ability to include resources such as images, and it is more flexible and easier to work with than RTF.

It is hard to believe this question sat for 15 months without anyone pointing out the easy way to do this.

The following site uses System.Management to accomplish the same is a very sleek way in a console application

An alternative way to do this could be select distinct PersonId and group join with persons:

var result = 
    from id in persons.Select(x => x.PersonId).Distinct()
    join p2 in persons on id equals p2.PersonId into gr // apply group join here
    select new 
    {
        PersonId = id,
        Cars = gr.Select(x => x.Car).ToList(),
    };

Or the same with fluent API syntax:

var result = persons.Select(x => x.PersonId).Distinct()
    .GroupJoin(persons, id => id, p => p.PersonId, (id, gr) => new
    {
        PersonId = id,
        Cars = gr.Select(x => x.Car).ToList(),
    });

GroupJoin produces a list of entries in the first list ( list of PersonId in our case), each with a group of joined entries in the second list (list of persons).

You don't need quotes around the variable, so simply change this:

Get-ADComputer -Filter {name -like '$nameregex' -and Enabled -eq "true"}

into this:

Get-ADComputer -Filter {name -like $nameregex -and Enabled -eq "true"}

Note, however, that the scriptblock notation for filter statements is misleading, because the statement is actually a string, so it's better to write it as such:

Get-ADComputer -Filter "name -like '$nameregex' -and Enabled -eq 'true'"

Related. Also related.

And FTR: you're using wildcard matching here (operator -like), not regular expressions (operator -match).

Operations are much faster when you work at the integer level. In particular, converting to a string as suggested here is really slow.

If you want bit 7 and 8 only, use e.g.

val = (byte >> 6) & 3

(this is: shift the byte 6 bits to the right - dropping them. Then keep only the last two bits 3 is the number with the first two bits set...)

These can easily be translated into simple CPU operations that are super fast.

none of the above answers worked for me. This one did:

=QUERY(Copy!A1:AP, "select AP, E, F, AO where AP="&E1&" ",1)

Closing a window that was opened by the user through JavaScript is considered to be a security risk, thus not all browsers will allow this (which is why all solutions are hacks/workarounds). Browsers that are steadily maintained remove these types of hacks, and solutions that work one day may be broken the next.

This was addressed here by rvighne in a similar question on the subject.

Simply add the below to your maven project pom.xml flie:

<dependencies>
          <dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-web-api</artifactId>
            <version>6.0</version>
            <scope>provided</scope>
         </dependency>
  </dependencies>

use only org.hibernate.dialect.OracleDialect Remove 10g,9 etc.

Github's libgit2 binding, pygit2 provides a one-liner cloning a remote directory:

clone_repository(url, path, 
    bare=False, repository=None, remote=None, checkout_branch=None, callbacks=None)

An easy, loop-free alternative is to use the horizontalalignment Text property as a keyword argument to xticks[1]. In the below, at the commented line, I've forced the xticks alignment to be "right".

n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')

plt.xticks(
        [0,1,2,3,4],
        ["this label extends way past the figure's left boundary",
        "bad motorfinger", "green", "in the age of octopus diplomacy", "x"], 
        rotation=45,
        horizontalalignment="right")    # here
plt.show()

(yticks already aligns the right edge with the tick by default, but for xticks the default appears to be "center".)

[1] You find that described in the xticks documentation if you search for the phrase "Text properties".

It's the last one:

a = a & b;

In Swift3:
let fileUrl = Foundation.URL(string: filePath)

Take the width of the table and divide it by the number of cell ().

PerformanceTable {width:500px;}    
PerformanceTable.td {width:100px;}

If the table dynamically widens or shrinks you could dynamically increase the cell size with a little javascript.

I think it's better to use the symmetric difference operation of sets to do that Here is the link to the doc.

>>> dict1 = {1:'donkey', 2:'chicken', 3:'dog'}
>>> dict2 = {1:'donkey', 2:'chimpansee', 4:'chicken'}
>>> set1 = set(dict1.items())
>>> set2 = set(dict2.items())
>>> set1 ^ set2
{(2, 'chimpansee'), (4, 'chicken'), (2, 'chicken'), (3, 'dog')}

It is symmetric because:

>>> set2 ^ set1
{(2, 'chimpansee'), (4, 'chicken'), (2, 'chicken'), (3, 'dog')}

This is not the case when using the difference operator.

>>> set1 - set2
{(2, 'chicken'), (3, 'dog')}
>>> set2 - set1
{(2, 'chimpansee'), (4, 'chicken')}

However it may not be a good idea to convert the resulting set to a dictionary because you may lose information:

>>> dict(set1 ^ set2)
{2: 'chicken', 3: 'dog', 4: 'chicken'}

All the other solutions posted here cause the toggle to get out of sync if it is double clicked. The following solution uses the events provided by the Bootstrap framework, and the toggle always matches the state of the collapsible element:

HTML:

<div class="row-fluid summary">
    <div class="span11">
        <h2>MyHeading</h2>  
    </div>
    <div class="span1">
        <button id="intro-switch" class="btn btn-success" data-toggle="collapse" data-target="#intro">+</button>
    </div>
</div>
<div class="row-fluid summary">
    <div id="intro" class="collapse"> 
        Here comes the text...
    </div>
</div>

JS:

$('#intro').on('show', function() {
  $('#intro-switch').html('-')
})
$('#intro').on('hide', function() {
  $('#intro-switch').html('+')
})

That should work for most cases.

However, I also ran into an additional problem when trying to nest one collapsible element and its toggle switch inside another collapsible element. With the above code, when I click the nested toggle to hide the nested collapsible element, the toggle for the parent element also changes. It may be a bug in Bootstrap. I found a solution that seems to work: I added a "collapsed" class to the toggle switches (Bootstrap adds this when the collapsible element is hidden but they don't start out with it), then added that to the jQuery selector for the hide function:

http://jsfiddle.net/fVpkm/87/

HTML:

<div class="row-fluid summary">
    <div class="span11">
        <h2>MyHeading</h2>  
    </div>
    <div class="span1">
        <button id="intro-switch" class="btn btn-success collapsed" data-toggle="collapse" data-target="#intro">+</button>
    </div>
</div>
<div class="row-fluid summary">
    <div id="intro" class="collapse"> 
        Here comes the text...<br>
        <a id="details-switch" class="collapsed" data-toggle="collapse" href="#details">Show details</a>
        <div id="details" class="collapse">
            More details...
        </div>
    </div>
</div>

JS:

$('#intro').on('show', function() {
    $('#intro-switch').html('-')
})
$('#intro').on('hide', function() {
    $('#intro-switch.collapsed').html('+')
})

$('#details').on('show', function() {
    $('#details-switch').html('Hide details')
})
$('#details').on('hide', function() {
    $('#details-switch.collapsed').html('Show details')
})

Python doesn't have a foreach statement per se. It has for loops built into the language.

for element in iterable:
    operate(element)

If you really wanted to, you could define your own foreach function:

def foreach(function, iterable):
    for element in iterable:
        function(element)

As a side note the for element in iterable syntax comes from the ABC programming language, one of Python's influences.

My issue was simple when i faced the following error:

objects are not valid as a react child (found object with keys {...}

was just that I was passing an object with keys specified in the error while trying to render the object directly in a component using {object} expecting it to be a string

object: {
    key1: "key1",
    key2: "key2"
}

while rendering on a React Component, I used something like below

render() {
    return this.props.object;
}

but it should have been

render() {
    return this.props.object.key1;
}

If you use Homebrew on OS X, then you have a simpler solution:

$ brew install go --with-cc-common # Linux, Darwin, and Windows

or..

$ brew install go --with-cc-all # All the cross-compilers

Use reinstall if you already have go installed.

I had a similar problem, made all the more infuriating by simply being very SLOW to update. I couldn't get my changes to take effect while working on the site to save my life (trying all manner of clearing my browser cache and cookies), but if I came back to the site later in the day or opened another browser, there they were.

I also solved the problem by disabling the Supercacher software at my host's cpanel (Siteground). You can also use the "flush" button for individual directories to test if that's it before disabling.

In android studio add/change this line at the end of gradle.properties (Global Properties):

...
org.gradle.jvmargs=-XX\:MaxHeapSize\=1024m -Xmx1024m 

if it doesn't work you can retry with bigger than 1024 heap size.

You have to use Convert.FromBase64String to turn a Base64 encoded string into a byte[].

catch (ReflectionTypeLoadException ex)
{        
    foreach (var item in ex.LoaderExceptions)
    {
          MessageBox.Show(item.Message);                    
    }
}

I'm sorry for resurrecting an old thread, but wanted to post a different solution to pull the loader exception (Using the actual ReflectionTypeLoadException) for anybody else to come across this.

See this CodePen https://codepen.io/ella301/pen/vYLNmVg which I created. I used 3 CSS functions min, max and calc to make sure the left and right paddings are fluid between minimum 20px and maximum 120px.

 padding: 20px max(min(120px, calc((100% - 1198px) / 2)), 20px);

Hope it helps!

How about this

var numbers = [1, 2, 3, 4, 5];
var option = '';

for (var i=0;i<numbers.length;i++){
     option += '<option value="'+ numbers[i] + '">' + numbers[i] + '</option>';
    }

    $('#items').append(option);

For the replacement portion, Python uses \1 the way sed and vi do, not $1 the way Perl, Java, and Javascript (amongst others) do. Furthermore, because \1 interpolates in regular strings as the character U+0001, you need to use a raw string or \escape it.

For something simple that work for arrays , strings , and objects I builed this function:

function console_testing($var){

    $var = json_encode($var,JSON_UNESCAPED_UNICODE);

    $output = <<<EOT
    <script>
        console.log($var);

EOT;

    echo $output;

}

I'll just post the code:

IPAddress ip = new IPAddress(new byte[] { 192, 168, 0, 1 });
int bits = 25;

uint mask = ~(uint.MaxValue >> bits);

// Convert the IP address to bytes.
byte[] ipBytes = ip.GetAddressBytes();

// BitConverter gives bytes in opposite order to GetAddressBytes().
byte[] maskBytes = BitConverter.GetBytes(mask).Reverse().ToArray();

byte[] startIPBytes = new byte[ipBytes.Length];
byte[] endIPBytes = new byte[ipBytes.Length];

// Calculate the bytes of the start and end IP addresses.
for (int i = 0; i < ipBytes.Length; i++)
{
    startIPBytes[i] = (byte)(ipBytes[i] & maskBytes[i]);
    endIPBytes[i] = (byte)(ipBytes[i] | ~maskBytes[i]);
}

// Convert the bytes to IP addresses.
IPAddress startIP = new IPAddress(startIPBytes);
IPAddress endIP = new IPAddress(endIPBytes);

If you comment out the following code from the _Layout.cshtml page, the modal popup will start working:

    </footer>

    @*@Scripts.Render("~/bundles/jquery")*@
    @RenderSection("scripts", required: false)
    </body>
</html>

In POJS, you add one listener at a time. It is not common to add the same listener for two different events on the same element. You could write your own small function to do the job, e.g.:

/* Add one or more listeners to an element
** @param {DOMElement} element - DOM element to add listeners to
** @param {string} eventNames - space separated list of event names, e.g. 'click change'
** @param {Function} listener - function to attach for each event as a listener
*/
function addListenerMulti(element, eventNames, listener) {
  var events = eventNames.split(' ');
  for (var i=0, iLen=events.length; i<iLen; i++) {
    element.addEventListener(events[i], listener, false);
  }
}

addListenerMulti(window, 'mousemove touchmove', function(){…});

Hopefully it shows the concept.

Edit 2016-02-25

Dalgard's comment caused me to revisit this. I guess adding the same listener for multiple events on the one element is more common now to cover the various interface types in use, and Isaac's answer offers a good use of built–in methods to reduce the code (though less code is, of itself, not necessarily a bonus). Extended with ECMAScript 2015 arrow functions gives:

function addListenerMulti(el, s, fn) {
  s.split(' ').forEach(e => el.addEventListener(e, fn, false));
}

A similar strategy could add the same listener to multiple elements, but the need to do that might be an indicator for event delegation.
