Using this way You will do a endless Loop on Your JS. to do a better way you can use the following

var on_submit_function = function(evt){
    evt.preventDefault(); //The form wouln't be submitted Yet.
    (...yourcode...)

    $(this).off('submit', on_submit_function); //It will remove this handle and will submit the form again if it's all ok.
    $(this).submit();
}

$('form').on('submit', on_submit_function); //Registering on submit.

I hope it helps! Thanks!

Yes, the GUI is available in XP. I can get the list of scheduled tasks (but not the GUI) to open with the following command,

control.exe  schedtasks

Then you can use the wizard to add a new scheduled task, for example.

In XP, you can find the Scheduler GUI from within Windows Help if you search for "Scheduled Tasks" then click on "Step by Step instructions" and open the scheduler GUI. Clicking on the last link executes the following command, which likely could be translatedinto something that would open the Scheduler GUI from the command line. Does anyone know how?

Customizing a ProgressBar requires defining the attribute or properties for the background and progress of your progress bar.

Create an XML file named customprogressbar.xml in your res->drawable folder:

custom_progressbar.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Define the background properties like color etc -->
    <item android:id="@android:id/background">
    <shape>
        <gradient
                android:startColor="#000001"
                android:centerColor="#0b131e"
                android:centerY="1.0"
                android:endColor="#0d1522"
                android:angle="270"
        />
    </shape>
   </item>

  <!-- Define the progress properties like start color, end color etc -->
  <item android:id="@android:id/progress">
    <clip>
        <shape>
            <gradient
                android:startColor="#007A00"
                android:centerColor="#007A00"
                android:centerY="1.0"
                android:endColor="#06101d"
                android:angle="270"
            />
        </shape>
    </clip>
    </item>
</layer-list> 

Now you need to set the progressDrawable property in customprogressbar.xml (drawable)

You can do this in the XML file or in the Activity (at run time).

Do the following in your XML:

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleHorizontal"
    android:progressDrawable="@drawable/custom_progressbar"         
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

At run time do the following

// Get the Drawable custom_progressbar                     
    Drawable draw=res.getDrawable(R.drawable.custom_progressbar);
// set the drawable as progress drawable
    progressBar.setProgressDrawable(draw);

Edit: corrected xml layout

public void run() {
    byte[] buffer = new byte[256];  
    int bytes;                      

    while (true) {
        try {
            bytes = mmInStream.read(buffer);
            mHandler.obtainMessage(RECIEVE_MESSAGE, bytes, -1, buffer).sendToTarget();
        } catch (IOException e) {
            break;
        }
    }
}

You could have is_hammer in terms of row["Open"] etc. as follows

def is_hammer(rOpen,rLow,rClose,rHigh):
    return lower_wick_at_least_twice_real_body(rOpen,rLow,rClose) \
       and closed_in_top_half_of_range(rHigh,rLow,rClose)

Then you can use map:

df["isHammer"] = map(is_hammer, df["Open"], df["Low"], df["Close"], df["High"])

If rather than the script, foo.R, knowing its path location, if you can change your code to always reference all source'd paths from a common root then these may be a great help:

• https://github.com/r-lib/rprojroot or https://rprojroot.r-lib.org/
• https://here.r-lib.org/

Given

• /app/deeply/nested/foo.R
• /app/other.R

This will work

#!/usr/bin/env Rscript
library(here)
source(here("other.R"))

See https://rprojroot.r-lib.org/ for how to define project roots.

To set Compatibility error

use this before using pivot function

ALTER DATABASE [dbname] SET COMPATIBILITY_LEVEL = 100  

Select the labels above the bar. Format Data Labels. Instead of selecting "VALUE" (unclick). SELECT Value from cells. Select the value. Use the following statement: if(cellvalue="","",cellvalue) where cellvalue is what ever the calculation is in the cell.

Official Developer Program

For a standard iPhone you'll need to pay the US$99/yr to be a member of the developer program. You can then use the adhoc system to install your application onto up to 100 devices. The developer program has the details but it involves adding UUIDs for each of the devices to your application package. UUIDs can be easiest retrieved using Ad Hoc Helper available from the App Store. For further details on this method, see Craig Hockenberry's Beta testing on iPhone 2.0 article

Jailbroken iPhone

For jailbroken iPhones, you can use the following method which I have personally tested using the AccelerometerGraph sample app on iPhone OS 3.0.

Create Self-Signed Certificate

First you'll need to create a self signed certificate and patch your iPhone SDK to allow the use of this certificate:

1. Launch Keychain Access.app. With no items selected, from the Keychain menu select Certificate Assistant, then Create a Certificate.

   Name: iPhone Developer
   Certificate Type: Code Signing
   Let me override defaults: Yes

2. Click Continue

   Validity: 3650 days

3. Click Continue

4. Blank out the Email address field.

5. Click Continue until complete.

   You should see "This root certificate is not trusted". This is expected.

6. Set the iPhone SDK to allow the self-signed certificate to be used:

   sudo /usr/bin/sed -i .bak 's/XCiPhoneOSCodeSignContext/XCCodeSignContext/' /Developer/Platforms/iPhoneOS.platform/Info.plist

   If you have Xcode open, restart it for this change to take effect.

Manual Deployment over WiFi

The following steps require openssh, and uikittools to be installed first. Replace jasoniphone.local with the hostname of the target device. Be sure to set your own password on both the mobile and root users after installing SSH.

To manually compile and install your application on the phone as a system app (bypassing Apple's installation system):

1. Project, Set Active SDK, Device and Set Active Build Configuration, Release.

2. Compile your project normally (using Build, not Build & Go).

3. In the build/Release-iphoneos directory you will have an app bundle. Use your preferred method to transfer this to /Applications on the device.

   scp -r AccelerometerGraph.app root@jasoniphone:/Applications/

4. Let SpringBoard know the new application has been installed:

   ssh [email protected] uicache

   This only has to be done when you add or remove applications. Updated applications just need to be relaunched.

To make life easier for yourself during development, you can setup SSH key authentication and add these extra steps as a custom build step in your project.

Note that if you wish to remove the application later you cannot do so via the standard SpringBoard interface and you'll need to use SSH and update the SpringBoard:

ssh [email protected] rm -r /Applications/AccelerometerGraph.app &&
ssh [email protected] uicache

The easiest way is to have a "wrapper" div element with a width set, and a left and right margin of auto.

Sample markup:

<!doctype html>
<html>
<head>
    <title></title>
    <style type="text/css">
        .wrapper { width: 960px; margin: 0 auto; background-color: #cccccc; }
        body { margin: 0; padding: 0 }
    </style>
</head>
<body>
    <div class="wrapper">
        your content...
    </div>
</body>
</html>

Go to Settings -> Style Configurator

Select Theme: Choose whichever you like best (the top two are easiest to read by most people's preference)

You can resolve this issue by downgrading Source Compatibility and Target Compatibility Java Version to 1.8 in Latest Android Studio Version 3.4.1

1. Open Module Settings (Project Structure) Winodw by right clicking on app folder or Command + Down Arrow on Mac

2. Go to Modules -> Properties

3. Change Source Compatibility and Target Compatibility Version to 1.8

4. Click on Apply or OK Thats it. It will solve your issue.

Also you can manually add in build.gradle (Module: app)

android {
...

compileOptions {
        sourceCompatibility = '1.8'
        targetCompatibility = '1.8'
    }

...
}

This is the one. The session will last for 1440 seconds (24 minutes).

session.gc_maxlifetime  1440    1440

Codes starting with 4 (4xx) are meant for client errors. Maybe 400 (Bad Request) could be suitable to this case? Definition in http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html says:

"The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications. "

This might be off-topic. But for the wget in for loop, you can certainly do

curl -O http://example.com/search/link[1-600]

The only safe way to protect your code is not giving it away. With client deployment, there is no avoiding the client having access to the code.

So the short answer is: You can't do it

The longer answer is considering flash or Silverlight. Although I believe silverlight will gladly give away it's secrets with reflector running on the client.

I'm not sure if something simular exists with the flash platform.

Define in msdn: https://msdn.microsoft.com/en-us/library/yd5xkb5c.aspx

int atoi(
   const char *str 
);
int _wtoi(
   const wchar_t *str 
);
int _atoi_l(
   const char *str,
   _locale_t locale
);
int _wtoi_l(
   const wchar_t *str,
   _locale_t locale
);

CString is wchar_t string. So, if you want convert Cstring to int, you can use:

 CString s;  
int test = _wtoi(s)

As mentioned in other answers you can use:

>> tic; x=5*ones(10,1); toc
Elapsed time is 0.000415 seconds.

An even faster method is:

>> tic;  x=5; x=x(ones(10,1)); toc
Elapsed time is 0.000257 seconds.

The Java language specification says you can have return with no expression if your method returns void.

X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);

store.Open(OpenFlags.ReadOnly);

foreach (X509Certificate2 certificate in store.Certificates){
    //TODO's
}

Check out fontsquirrel. They have a web font generator, which will also spit out a suitable stylesheet for your font (look for "@font-face kit"). This stylesheet can be included in your own, or you can use it as a template.

The following is more Drupal-ish:

url(current_path(), array('absolute' => true)); 

As stated, use TextView.setText(Html.fromHtml(String))

And use these tags in your Html formatted string:

<a href="...">

<big>
<blockquote>
<br>
<cite>
<dfn>
<div align="...">
<em>
<font size="..." color="..." face="...">

As far as I know, there isn't any better way in terms of working with Reflection library in a smarter way. However, you could use LINQ to make the code a bit nicer:

var props = from p in t.GetProperties()
            let attrs = p.GetCustomAttributes(typeof(MyAttribute), true)
            where attrs.Length != 0 select p;

// Do something with the properties in 'props'

I believe this helps you to structure the code in a more readable fashion.

The git-cache-meta mentioned in SO question "git - how to recover the file permissions git thinks the file should be?" (and the git FAQ) is the more staightforward approach.

The idea is to store in a .git_cache_meta file the permissions of the files and directories.
It is a separate file not versioned directly in the Git repo.

That is why the usage for it is:

$ git bundle create mybundle.bdl master; git-cache-meta --store
$ scp mybundle.bdl .git_cache_meta machine2: 
#then on machine2:
$ git init; git pull mybundle.bdl master; git-cache-meta --apply

So you:

• bundle your repo and save the associated file permissions.
• copy those two files on the remote server
• restore the repo there, and apply the permission

This works because Integer::min resolves to an implementation of the Comparator<Integer> interface.

The method reference of Integer::min resolves to Integer.min(int a, int b), resolved to IntBinaryOperator, and presumably autoboxing occurs somewhere making it a BinaryOperator<Integer>.

And the min() resp max() methods of the Stream<Integer> ask the Comparator<Integer> interface to be implemented.
Now this resolves to the single method Integer compareTo(Integer o1, Integer o2). Which is of type BinaryOperator<Integer>.

And thus the magic has happened as both methods are a BinaryOperator<Integer>.

Here i tried with this approach :

import numpy as np
#converting to one_hot





def one_hot_encoder(value, datal):

    datal[value] = 1

    return datal


def _one_hot_values(labels_data):
    encoded = [0] * len(labels_data)

    for j, i in enumerate(labels_data):
        max_value = [0] * (np.max(labels_data) + 1)

        encoded[j] = one_hot_encoder(i, max_value)

    return np.array(encoded)

What fixed this for me was re-setting my origin url:

git remote set-url origin https://github.com/username/example_repo.git

And then I was able to successfully git push my project. I had to do this even though when I viewed my origins with git remote -v, that the urls were same as what I re-set it as.

just simple:

.navbar{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

or,

.navbar.navbar-fixed-top{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

Hope it works (at least, for future searchers)

This is largely a duplicate of another question.

Here's the section of that answer that is relevant to this question:

Do I need to do my own synchronization if I use java.util.ConcurrentLinkedQueue?

Atomic operations on the concurrent collections are synchronized for you. In other words, each individual call to the queue is guaranteed thread-safe without any action on your part. What is not guaranteed thread-safe are any operations you perform on the collection that are non-atomic.

For example, this is threadsafe without any action on your part:

queue.add(obj);

or

queue.poll(obj);

However; non-atomic calls to the queue are not automatically thread-safe. For example, the following operations are not automatically threadsafe:

if(!queue.isEmpty()) {
   queue.poll(obj);
}

That last one is not threadsafe, as it is very possible that between the time isEmpty is called and the time poll is called, other threads will have added or removed items from the queue. The threadsafe way to perform this is like this:

synchronized(queue) {
    if(!queue.isEmpty()) {
       queue.poll(obj);
    }
}

Again...atomic calls to the queue are automatically thread-safe. Non-atomic calls are not.

string query = "SELECT column_name FROM table_name";      //query the database
SqlCommand queryStatus = new SqlCommand(query, myConnection);
sqlDataReader reader = queryStatus.ExecuteReader();                               
            
while (reader.Read())   //loop reader and fill the combobox
{
ComboBox1.Items.Add(reader["column_name"].ToString());
}

You can use EL if you want to work as IF:

<h:outputLabel value="#{row==10? '10' : '15'}"/>

Changing styles or classes:

style="#{test eq testMB.test? 'font-weight:bold' : 'font-weight:normal'}"

class="#{test eq testMB.test? 'divRred' : 'divGreen'}"

cmsjr had the right solution. I just wanted to point out a couple of things for your future trigger development. If you are using the values statement in an insert in a trigger, there is a stong possibility that you are doing the wrong thing. Triggers fire once for each batch of records inserted, deleted, or updated. So if ten records were inserted in one batch, then the trigger fires once. If you are refering to the data in the inserted or deleted and using variables and the values clause then you are only going to get the data for one of those records. This causes data integrity problems. You can fix this by using a set-based insert as cmsjr shows above or by using a cursor. Don't ever choose the cursor path. A cursor in a trigger is a problem waiting to happen as they are slow and may well lock up your table for hours. I removed a cursor from a trigger once and improved an import process from 40 minutes to 45 seconds.

You may think nobody is ever going to add multiple records, but it happens more frequently than most non-database people realize. Don't write a trigger that will not work under all the possible insert, update, delete conditions. Nobody is going to use the one record at a time method when they have to import 1,000,000 sales target records from a new customer or update all the prices by 10% or delete all the records from a vendor whose products you don't sell anymore.

It's incorrect, but you can try this instead:

select
    a.x,
    ( select b.y from b where b.v = a.v) as by,
    ( select b.z from b where b.v = a.v) as bz
from a

you can also use subquery in join

 select
        a.x,
        b.y,
        b.z
    from a
    left join (select y,z from b where ... ) b on b.v = a.v

or

   select
        a.x,
        b.y,
        b.z
    from a
    left join b on b.v = a.v

To my knowledge the setTimeout function is called asynchronously. What you can do is wrap the entire loop within an async function and await a Promise that contains the setTimeout as shown:

var looper = async function () {
  for (var start = 1; start < 10; start++) {
    await new Promise(function (resolve, reject) {
      setTimeout(function () {
        console.log("iteration: " + start.toString());
        resolve(true);
      }, 1000);
    });
  }
  return true;
}

And then you call run it like so:

looper().then(function(){
  console.log("DONE!")
});

Please take some time to get a good understanding of asynchronous programming.

Always keep in mind when you want to overcome this error, the default value of indexing and range starts from 0, so if total items is 100 then l[99] and range(99) will give you access up to the last element.

whenever you get this type of error please cross check with items that comes between/middle in range, and insure that their index is not last if you get output then you have made perfect error that mentioned above.

You could also look at using OpenRowSet with the CSV text file data provider.

This should be possible with any version of SQL Server >= 2005 although you need to enable the feature.

In javascript the "+" operator is used to add numbers or to concatenate strings. if one of the operands is a string "+" concatenates, and if it is only numbers it adds them.

example:

1+2+3 == 6
"1"+2+3 == "123"

Use numeric(n,n) where n has enough resolution to round to 1.00. For instance:

declare @discount numeric(9,9)
    , @quantity int
select @discount = 0.999999999
    , @quantity = 10000

select convert(money, @discount * @quantity)

For example:

<EditText
android:id="@+id/myNumber"
android:digits="0123456789."
android:inputType="numberDecimal"
/>

If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit

var thisIsObject= {
    'Cow' : 'Moo',
    'Cat' : 'Meow',
    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

Check if you have hidden it... Use Alt+6 to bring up the window and click on the button shown below 'Restore logcat view'

You can also set defaults by file extension using RCDefaultApp:

potentially you could set .sh to open in iTerm/Terminal etc. it would need user execute permissions, eg

chmod u+x filename.sh

just use class='text-center' in element for center heading.

<h2 class="text-center">sample center heading</h2>

use class='text-left' in element for left heading, and use class='text-right' in element for right heading.

It seems like you installed a zip version of sbt, which is fine. But I suggest you install the native debian package if you are on Ubuntu. That is how I managed to install it on my Ubuntu 12.04. Check it out here: http://www.scala-sbt.org/release/docs/Installing-sbt-on-Linux.html Or simply directly download it from here.

For me it was enough to use

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime StartDate { set; get; }

You can specify become_method to override the default method set in ansible.cfg (if any), and which can be set to one of sudo, su, pbrun, pfexec, doas, dzdo, ksu.

- name: I am confused
  command: 'whoami'
  become: true
  become_method: su
  become_user: some_user
  register: myidentity

- name: my secret identity
  debug:
    msg: '{{ myidentity.stdout }}'

Should display

TASK [my-task : my secret identity] ************************************************************
ok: [my_ansible_server] => {
    "msg": "some_user"
}

I recommend you to use an unordered list for your image gallery.

You should use my code unless you want the image to gain instantly 50% opacity after you hover out. You will have a smoother transition.

#photos li {
    opacity: .5;
    transition: opacity .5s ease-out;
    -moz-transition: opacity .5s ease-out;
    -webkit-transition: opacity .5s ease-out;
    -o-transition: opacity .5s ease-out;
}

#photos li:hover {
    opacity: 1;
}

Say it like this: struct xyx a;

the problem is in flow annotation in handleClick, i removed this and works fine thanks @alik

The parameter to the COUNT function is an expression that is to be evaluated for each row. The COUNT function returns the number of rows for which the expression evaluates to a non-null value. ( * is a special expression that is not evaluated, it simply returns the number of rows.)

There are two additional modifiers for the expression: ALL and DISTINCT. These determine whether duplicates are discarded. Since ALL is the default, your example is the same as count(ALL 1), which means that duplicates are retained.

Since the expression "1" evaluates to non-null for every row, and since you are not removing duplicates, COUNT(1) should always return the same number as COUNT(*).

This syntax isn't valid in any version of PostgreSQL:

ALTER SEQUENCE payments_id_seq LASTVALUE 22

This would work:

ALTER SEQUENCE payments_id_seq RESTART WITH 22;

And is equivalent to:

SELECT setval('payments_id_seq', 22, FALSE);

More in the current manual for ALTER SEQUENCE and sequence functions.

Note that setval() expects either (regclass, bigint) or (regclass, bigint, boolean). In the above example I am providing untyped literals. That works too. But if you feed typed variables to the function you may need explicit type casts to satisfy function type resolution. Like:

SELECT setval(my_text_variable::regclass, my_other_variable::bigint, FALSE);

For repeated operations you might be interested in:

ALTER SEQUENCE payments_id_seq START WITH 22; -- set default
ALTER SEQUENCE payments_id_seq RESTART;       -- without value

START [WITH] stores a default RESTART number, which is used for subsequent RESTART calls without value. You need Postgres 8.4 or later for the last part.

Regarding idioms, there is an itertools recipe called nth.

From itertools recipes:

def nth(iterable, n, default=None):
    "Returns the nth item or a default value"
    return next(islice(iterable, n, None), default)

If you want one-liners, consider installing a library that implements this recipe for you, e.g. more_itertools:

import more_itertools as mit

mit.nth([3, 2, 1], 0)
# 3

mit.nth([], 0)                                             # default is `None`
# None

Another tool is available that only returns the first item, called more_itertools.first.

mit.first([3, 2, 1])
# 3

mit.first([], default=None)
# None

These itertools scale generically for any iterable, not only for lists.

X * 2 = 1 bit shift left
X / 2 = 1 bit shift right
X * 3 = shift left 1 bit and then add X

I don't have IE8 to test this out, but I'm pretty sure it should work:

<div class="screen">
   <!-- code -->
   <div class="innerdiv">
      text or other content
   </div>
</div>

and the css:

.screen{
position: relative;
}
.innerdiv {
position: absolute;
bottom: 0;
right: 0;
}

This should place the .innerdiv in the bottom-right corner of the .screen class. I hope this helps :)

Closing IIS Express

By default Visual Studio places the IISExpress icon in your system tray at the lower right hand side of your screen, by the clock. You can right click it and choose exit. If you don't see the icon, try clicking the small arrow to view the full list of icons in the system tray.

then right click and choose Exit:

Changing the Port

Another option is to change the port by modifying the project properties. You'll need to do this for each web project in your solution.

1. Visual Studio > Solution Explorer
2. Right click the web project and choose Properties
3. Go to the Web tab
4. In the 'Servers' section, change the port in the Project URL box
5. Repeat for each web project in the solution

If All Else Fails

If that doesn't work, you can try to bring up Task Manager and close the IIS Express System Tray (32 bit) process and IIS Express Worker Process (32 bit).

If it still doesn't work, as ni5ni6 pointed out, there is a 'Web Deployment Agent Service' running on the port 80. Use this article to track down which process uses it, and turn it off:

https://sites.google.com/site/anashkb/port-80-in-use

Do what blak3r suggested and define your targets classpath like so

<taskdef resource="net/sf/antcontrib/antlib.xml">
    <classpath>
        <fileset dir="lib">
          <include name="**/*.jar"/>
        </fileset>
    </classpath>        
</taskdef>

where lib is where you store your jar's

Open an elevated Command Prompt (run cmd as administrator). query your registry for available TT fonts to the console by:

    REG query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont"

You'll see an output like :

    0    REG_SZ    Lucida Console
    00    REG_SZ    Consolas
    936    REG_SZ    *???
    932    REG_SZ    *MS ????

Now we need to add a TT font that supports the characters you need like Courier New, we do this by adding zeros to the string name, so in this case the next one would be "000" :

    REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont" /v 000 /t REG_SZ /d "Courier New"

Now we implement UTF-8 support:

    REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f

Set default font to "Courier New":

    REG ADD HKCU\Console /v FaceName /t REG_SZ /d "Courier New" /f

Set font size to 20 :

    REG ADD HKCU\Console /v FontSize /t REG_DWORD /d 20 /f

Enable quick edit if you like :

    REG ADD HKCU\Console /v QuickEdit /t REG_DWORD /d 1 /f

In addition to other nice answers, a quote from Linux system programming written by Google's expert Robert Love:

Advantages of mmap( )

Manipulating files via mmap( ) has a handful of advantages over the standard read( ) and write( ) system calls. Among them are:

• Reading from and writing to a memory-mapped file avoids the extraneous copy that occurs when using the read( ) or write( ) system calls, where the data must be copied to and from a user-space buffer.

• Aside from any potential page faults, reading from and writing to a memory-mapped file does not incur any system call or context switch overhead. It is as simple as accessing memory.

• When multiple processes map the same object into memory, the data is shared among all the processes. Read-only and shared writable mappings are shared in their entirety; private writable mappings have their not-yet-COW (copy-on-write) pages shared.

• Seeking around the mapping involves trivial pointer manipulations. There is no need for the lseek( ) system call.

For these reasons, mmap( ) is a smart choice for many applications.

Disadvantages of mmap( )

There are a few points to keep in mind when using mmap( ):

• Memory mappings are always an integer number of pages in size. Thus, the difference between the size of the backing file and an integer number of pages is "wasted" as slack space. For small files, a significant percentage of the mapping may be wasted. For example, with 4 KB pages, a 7 byte mapping wastes 4,089 bytes.

• The memory mappings must fit into the process' address space. With a 32-bit address space, a very large number of various-sized mappings can result in fragmentation of the address space, making it hard to find large free contiguous regions. This problem, of course, is much less apparent with a 64-bit address space.

• There is overhead in creating and maintaining the memory mappings and associated data structures inside the kernel. This overhead is generally obviated by the elimination of the double copy mentioned in the previous section, particularly for larger and frequently accessed files.

For these reasons, the benefits of mmap( ) are most greatly realized when the mapped file is large (and thus any wasted space is a small percentage of the total mapping), or when the total size of the mapped file is evenly divisible by the page size (and thus there is no wasted space).

Recently I faced the same issue. I got the following error:

repository access denied. access via a deployment key is read-only.

You can have two kinds of SSH keys:

1. For your entire account which will work for all repositories
2. Per repository SSH key which can only be used for that specific repository.

I simply removed my repository SSH key and added a new SSH key to my account and it worked well.

I hope it helps someone. Cheers

My understanding of margin and padding comes from google's developer tool in the image attached

In Simple words, a margin is the space around an element and padding means the space between an element and the content inside that element. Both these two are used to create gaps but in different ways.

Using Margin to create gap:

In creating gap margin pushes the adjacent elements away

Using Padding to create gap:

Using padding to create gap either grows the element's size or shrinks the content inside

Why is it important to know the difference?

It is important to know the difference so you could know when to use either of them and use them appropriately.

It is also worthy of note that margins and padding come handy when designing a website's layout, as margin specifies whether an element will move up or down, left or right while padding specifies how an element will look and sit inside its container.

Error 3027: No mapping specified for the following EntitySet/AssociationSet ..." - Entity Framework headaches

If you are developing model with Entities Framework then you may run into this annoying error at times:

Error 3027: No mapping specified for the following EntitySet/AssociationSet [Entity or Association Name]

This may make no sense when everything looks fine on the EDM, but that's because this error has nothing to do with the EDM usually. What it should say is "regenerate your database files".

You see, Entities checks against the SSDL and MSL during build, so if you just changed your EDM but doesn't use Generate Database Model... then it complains that there's stuff missing in your sql scripts.

so, in short, the solution is: "Don't forget to Generate Database Model every time after you update your EDM if you are doing model first development. I hope your problem is solved".

A simpler way is

ggplot(data=df, aes(x=xvar, y=yvar)) + 
geom_point()

ggsave(path = path, width = width, height = height, device='tiff', dpi=700)

Here is a practical example of Anchor tag with different

Target Attribute

Short answer: Why not?

Longer answer: The time itself doesn't really matter, as long as everyone who uses it agrees on its value. As 1/1/70 has been in use for so long, using it will make you code as understandable as possible for as many people as possible.

There's no great merit in choosing an arbitrary epoch just to be different.

The difference between the two is best brought in what seems a necessary and sufficient definition of the dependencyManagement element available in Maven website docs:

dependencyManagement

"Default dependency information for projects that inherit from this one. The dependencies in this section are not immediately resolved. Instead, when a POM derived from this one declares a dependency described by a matching groupId and artifactId, the version and other values from this section are used for that dependency if they were not already specified." [ https://maven.apache.org/ref/3.6.1/maven-model/maven.html ]

It should be read along with some more information available on a different page:

“..the minimal set of information for matching a dependency reference against a dependencyManagement section is actually {groupId, artifactId, type, classifier}. In many cases, these dependencies will refer to jar artifacts with no classifier. This allows us to shorthand the identity set to {groupId, artifactId}, since the default for the type field is jar, and the default classifier is null.” [https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html ]

Thus, all the sub-elements (scope, exclusions etc.,) of a dependency element--other than groupId, artifactId, type, classifier, not just version--are available for lockdown/default at the point (and thus inherited from there onward) you specify the dependency within a dependencyElement. If you’d specified a dependency with the type and classifier sub-elements (see the first-cited webpage to check all sub-elements) as not jar and not null respectively, you’d need {groupId, artifactId, classifier, type} to reference (resolve) that dependency at any point in an inheritance originating from the dependencyManagement element. Else, {groupId, artifactId} would suffice if you do not intend to override the defaults for classifier and type (jar and null respectively). So default is a good keyword in that definition; any sub-element(s) (other than groupId, artifactId, classifier and type, of course) explicitly assigned value(s) at the point you reference a dependency override the defaults in the dependencyManagement element.

So, any dependency element outside of dependencyManagement, whether as a reference to some dependencyManagement element or as a standalone is immediately resolved (i.e. installed to the local repository and available for classpaths).

Try setting the contentSize's height to the scrollView's height. Then the vertical scroll should be disabled because there would be nothing to scroll vertically.

scrollView.contentSize = CGSizeMake(scrollView.contentSize.width,scrollView.frame.size.height);

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

I usually use a plain old VARCHAR filtering for an IPAddress works fine.

If you want to filter on ranges of IP address I'd break it into four integers.

I solved a similar problem by updating the web.xml declaration to Servlet 4.0 specification as follows (I use Tomcat 9) :

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                          http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
      version="4.0"
      metadata-complete="true">
      <!-- ... (your content here) ... -->
</web-app>

You can check which servlet version Tomcat supports by refering to the chart on Tomcat's which version page.

The problem is your gradle build is not finding the JAVA_HOME path or JDK folder. So, you could declare the path in gradle.properties like org.gradle.java.home=C:\Program Files\Java\[or yours jdk folder name].

Use this guide for using gradle.properties.

Or (and I prefer this solution) include JAVA_HOME path in systmem variables and restart CMD.

DeZign for Databases might be interesting for you. You can reverse engineer and modify existing databases. Has got an auto-layout function and diagram layout is not meshed up when synchronizing your data model with the database.

can you try if.else

> col2=ifelse(df1$col=="true",1,0)
> df1
$col
[1] "true"  "false"

> cbind(df1$col)
     [,1]   
[1,] "true" 
[2,] "false"
> cbind(df1$col,col2)
             col2
[1,] "true"  "1" 
[2,] "false" "0" 

I've seen it done. I wouldn't recommend it. C++ originally started this way as a preprocessor that produced C code as an intermediate step.

Essentially what you end up doing is create a dispatch table for all of your methods where you store your function references. Deriving a class would entail copying this dispatch table and replacing the entries that you wanted to override, with your new "methods" having to call the original method if it wants to invoke the base method. Eventually, you end up rewriting C++.

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

For me it turned out to be an relative symbolic link (to the referenced project) that couldn't be used by grade. (I was referencing a library). Thats a pretty edgy edge-case but maybe it helps someone in the future.

I solved it by putting a absolute symbolic link.

Before ln -s ../library after ln -s /the/full/path/to/the/library

Another option is slice

library(dplyr)
group %>%
     group_by(Subject) %>%
     slice(which.max(pt))
#    Subject    pt Event
#    <dbl> <dbl> <dbl>
#1       1     5     2
#2       2    17     2
#3       3     5     2

Quick fix that worked for me:

for file in $(find "$JAVA_HOME" -name "*pack")
do 
    unpack200 "${file}" "${test_file/%pack/jar}";
done

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

For anyone coming here from search results and are targeting Android 10: Android 10 (API 29) changes some permissions related to storage.

I fixed the issue when I replaced my previous instances of Environment.getExternalStorageDirectory() (which is deprecated with API 29) with context.getExternalFilesDir(null).

Note that context.getExternalFilesDir(type) can return null if the storage location isn't available, so be sure to check that whenever you're checking if you have external permissions.

Read more here.

we can use

 element[role="ourRole"] {
    requried style !important; /*for overriding the old css styles */
    }

The simplest way in laravel 5 is:

$listings=Listing::take(10)->get();

return view('view.name',compact('listings'));

If you're using Joda-Time (and there are lots of good reasons to - a simple, intuitive API and thread-safety) then you can do this trivially:

(new LocalDate()).plusDays(5);

to give 5 days from today, for example.

EDIT: My current advice would be to now use the Java 8 date/time api

What is the best practice on where the logic for the @foreach should be at?

Nowhere, just get rid of it. You could use editor or display templates.

So for example:

@foreach (var item in Model.Foos)
{
    <div>@item.Bar</div>
}

could perfectly fine be replaced by a display template:

@Html.DisplayFor(x => x.Foos)

and then you will define the corresponding display template (if you don't like the default one). So you would define a reusable template ~/Views/Shared/DisplayTemplates/Foo.cshtml which will automatically be rendered by the framework for each element of the Foos collection (IEnumerable<Foo> Foos { get; set; }):

@model Foo
<div>@Model.Bar</div>

Obviously exactly the same conventions apply for editor templates which should be used in case you want to show some input fields allowing you to edit the view model in contrast to just displaying it as readonly.

use your jsonsimpleobject direclty like below

JSONObject unitsObj = parser.parse(new FileReader("file.json");

For those who tried gkalpak answer and it did not work,

be aware that chrome will add the content script to a needed page only when your extension enabled during chrome launch and also a good idea restart browser after making these changes

An Error Was Encountered Unable to load the requested file:

Sometimes we face this error because the requested file doesn't exist in that directory.

Suppose we have a folder home in views directory and trying to load home_view.php file as:

$this->load->view('home/home_view', $data);// $data is array

If home_view.php file doesn't exist in views/home directory then it will raise an error.

An Error Was Encountered Unable to load the requested file: home\home_view.php

So how to fix this error go to views/home and check the home_view.php file exist if not then create it.

This mini javascript libary (1.3 KB) can do all these things

nor.event(["#first"], ["touchstart", "click"], [doSomething, doSomething]);

Note that you can still do:

s[0] = 'h';

Keep in mind that Windows has virtual memory management and the JVM only needs memory that is contiguous in its address space. So, other programs running on the system shouldn't necessarily impact your heap size. What will get in your way are DLL's that get loaded in to your address space. Unfortunately optimizations in Windows that minimize the relocation of DLL's during linking make it more likely you'll have a fragmented address space. Things that are likely to cut in to your address space aside from the usual stuff include security software, CBT software, spyware and other forms of malware. Likely causes of the variances are different security patches, C runtime versions, etc. Device drivers and other kernel bits have their own address space (the other 2GB of the 4GB 32-bit space).

You could try going through your DLL bindings in your JVM process and look at trying to rebase your DLL's in to a more compact address space. Not fun, but if you are desperate...

Alternatively, you can just switch to 64-bit Windows and a 64-bit JVM. Despite what others have suggested, while it will chew up more RAM, you will have much more contiguous virtual address space, and allocating 2GB contiguously would be trivial.

Try this query

 SELECT  data_collector_id , count (data_collector_id ) as frequency 
    from rent_flats 
    where is_contact_person_landlord = 'True' 
    GROUP BY data_collector_id 
    ORDER BY count(data_collector_id) DESC

By changing runProguard to minifyEnabled, part of the issue gets fixed.

But the fix can cause "Library Projects cannot set application Id" (you can find the fix for this here Android Studio 1.0 and error "Library projects cannot set applicationId").

By removing application Id in the build.gradle file, you should be good to go.

Swift 3: You can create a UIButton programmatically

either inside a methods scope for example in ViewDidLoad() Be sure to add constraints to the button, otherwise you wont see it

let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.target(forAction: #selector(buttonAction), withSender: self)
//button.backgroundColor etc

view.addSubview(button)

@objc func buttonAction() {
   //some Action
}

or outside your scope as global variable to access it from anywhere in your module

let button: UIButton = {
   let b = UIButton()
   b.translatesAutoresizingMaskIntoConstraints = false
   //b.backgroundColor etc
   return b
}()

and then you setup the constraints

func setupButtonView() {
   view.addSubview(button)
   button.widthAnchor.constraint(equalToConstant: 40).isActive = true
   button.heightAnchor.constraint(equalToConstant: 40).isActive = true
   // etc

}

sudo apt install aptitude

Several answers already suggest how to query the current python version. To check programmatically the version requirements, I'd make use of one of the following two methods:

# Method 1: (see krawyoti's answer)
import sys
assert(sys.version_info >= (2,6))

# Method 2: 
import platform
from distutils.version import StrictVersion 
assert(StrictVersion(platform.python_version()) >= "2.6")

You can modify the id without having to use getElementById

Example:

<div id = 'One' onclick = "One.id = 'Two'; return false;">One</div>

You can see it here: http://jsbin.com/elikaj/1/

Solution 1 - you need to change your backend to accept your incoming requests

Solution 2 - using Angular proxy see here

Please note this is only for ng serve, you can't use proxy in ng build

Note: the reason it's working via postman is postman doesn't send preflight requests while your browser does.

The numpy array I was trying to normalize was an integer array. It seems they deprecated type casting in versions > 1.10, and you have to use numpy.true_divide() to resolve that.

arr = np.array(img)
arr = np.true_divide(arr,[255.0],out=None)

img was an PIL.Image object.

If anyone ever needs it - Here is a recursive average.

In the context of the original question, you may want to use the recursive average if you allowed the user to insert additional values and, without incurring the cost of visiting each element again, wanted to "update" the existing average.

/**
 * Computes the recursive average of an indefinite set
 * @param {Iterable<number>} set iterable sequence to average
 * @param {number} initAvg initial average value
 * @param {number} initCount initial average count
 */
function average(set, initAvg, initCount) {
  if (!set || !set[Symbol.iterator])
    throw Error("must pass an iterable sequence");

  let avg = initAvg || 0;
  let avgCnt = initCount || 0;
  for (let x of set) {
    avgCnt += 1;
    avg = avg * ((avgCnt - 1) / avgCnt) + x / avgCnt;
  }
  return avg; // or {avg: avg, count: avgCnt};
}

average([2, 4, 6]);    //returns 4
average([4, 6], 2, 1); //returns 4
average([6], 3, 2);    //returns 4
average({
  *[Symbol.iterator]() {
    yield 2; yield 4; yield 6;
  }
});                    //returns 4

How:

this works by maintaining the current average and element count. When a new value is to be included you increment count by 1, scale the existing average by (count-1) / count, and add newValue / count to the average.

Benefits:

• you don't sum all the elements, which may result in large number that cannot be stored in a 64-bit float.
• you can "update" an existing average if additional values become available.
• you can perform a rolling average without knowing the sequence length.

Downsides:

• incurs lots more divisions
• not infinite - limited to Number.MAX_SAFE_INTEGER items unless you employ BigNumber

System.setProperty is not working for applets. Because JVM already running before applet start. In this case we use applet parameters like this:

    deployJava.runApplet({
        id: 'MyApplet',
        code: 'com.mkysoft.myapplet.SomeClass',
        archive: 'com.mkysoft.myapplet.jar'
    }, {
        java_version: "1.6*", // Target version
        cache_option: "no",
        cache_archive: "",
        codebase_lookup: true,
        java_arguments: "-Djava.net.preferIPv4Stack=true"
    },
       "1.6" // Minimum version
    );

To load local resources in Chrome when just using your local computer and not using a webserver you need to add the --allow-file-access-from-files flag.

You can have a shortcut to Chrome that allows files access and one that does not.

Create a shortcut for Chrome on the desktop, right click on shortcut, select properties. In the dialog box that opens find the target for the short cut and add the parameter after chrome.exe leaving a space

eg C:\PATH TO\chrome.exe --allow-file-access-from-files

This shortcut will allow access to files without affecting any other shortcut to Chrome you have.

When you open Chrome with this shortcut it should allow local resources to be loaded using HTML5 and the filesystem api

The exact details differ a bit in .NET Framework vs .NET Core, but it also somewhat depends on what you're doing: if you're using an ICollection or ICollection<T> type (such as with List<T>) there is a .Count property that's cheap to access, whereas other types might require enumeration.

TL;DR:

Use .Count > 0 if the property exists, and otherwise .Any().

Using .Count() > 0 is never the best option, and in some cases could be dramatically slower.

This applies to both .NET Framework and .NET Core.

Now we can dive into the details..

Lists and Collections

Let's start with a very common case: using List<T> (which is also ICollection<T>).

The .Count property is implemented as:

    private int _size;

    public int Count {
        get {
            Contract.Ensures(Contract.Result<int>() >= 0);
            return _size; 
        }
    }

What this is saying is _size is maintained by Add(),Remove() etc, and since it's just accessing a field this is an extremely cheap operation -- we don't need to iterate over values.

ICollection and ICollection<T> both have .Count and most types that implement them are likely to do so in a similar way.

Other IEnumerables

Any other IEnumerable types that aren't also ICollection require starting enumeration to determine if they're empty or not. The key factor affecting performance is if we end up enumerating a single item (ideal) or the entire collection (relatively expensive).

If the collection is actually causing I/O such as by reading from a database or disk, this could be a big performance hit.

.NET Framework .Any()

In .NET Framework (4.8), the Any() implementation is:

public static bool Any<TSource>(this IEnumerable<TSource> source) {
    if (source == null) throw Error.ArgumentNull("source");
    using (IEnumerator<TSource> e = source.GetEnumerator()) {
        if (e.MoveNext()) return true;
    }
    return false;
}

This means no matter what, it's going to get a new enumerator object and try iterating once. This is more expensive than calling the List<T>.Count property, but at least it's not iterating the entire list.

.NET Framework .Count()

In .NET Framework (4.8), the Count() implementation is (basically):

public static int Count<TSource>(this IEnumerable<TSource> source)
{
    ICollection<TSource> collection = source as ICollection<TSource>;
    if (collection != null)
    { 
        return collection.Count;
    }
    int num = 0;
    using (IEnumerator<TSource> enumerator = source.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            num = checked(num + 1);
        }
        return num;
    }
}

If available, ICollection.Count is used, but otherwise the collection is enumerated.

.NET Core .Any()

The LINQ Any() implementation in .NET Core is much smarter. You can see the complete source here but the relevant bits to this discussion:

    public static bool Any<TSource>(this IEnumerable<TSource> source)
    {
        //..snip..
        
        if (source is ICollection<TSource> collectionoft)
        {
            return collectionoft.Count != 0;
        }
        
        //..snip..

        using (IEnumerator<TSource> e = source.GetEnumerator())
        {
            return e.MoveNext();
        }
    }

Because a List<T> is an ICollection<T>, this will call the Count property (and though it calls another method, there's no extra allocations).

.NET Core .Count()

The .NET Core implementation (source) is basically the same as .NET Framework (see above), and so it will use ICollection.Count if available, and otherwise enumerates the collection.

Summary

.NET Framework

• With ICollection:

  • .Count > 0 is best
  • .Count() > 0 is fine, but ultimately just calls ICollection.Count
  • .Any() is going to be slower, as it enumerates a single item

• With non-ICollection (no .Count property)

  • .Any() is best, as it only enumerates a single item
  • .Count() > 0 is bad as it causes complete enumeration

.NET Core

• .Count > 0 is best, if available (ICollection)
• .Any() is fine, and will either do ICollection.Count > 0 or enumerate a single item
• .Count() > 0 is bad as it causes complete enumeration

Well, why do you have %20 url-quoting escapes in a formatting string in first place? Ideally you'd do the interpolation formatting first:

formatting_template = 'Hello World%s'
text = '!'
full_string = formatting_template % text

Then you url quote it afterwards:

result = urllib.quote(full_string)

That is better because it would quote all url-quotable things in your string, including stuff that is in the text part.

BorderLayout(int Gap, int Gap) or GridLayout(int Gap, int Gap, int Gap, int Gap)

why paint Border() inside paintComponent( ...)

    Border line, raisedbevel, loweredbevel, title, empty;
    line = BorderFactory.createLineBorder(Color.black);
    raisedbevel = BorderFactory.createRaisedBevelBorder();
    loweredbevel = BorderFactory.createLoweredBevelBorder();
    title = BorderFactory.createTitledBorder("");
    empty = BorderFactory.createEmptyBorder(4, 4, 4, 4);
    Border compound = BorderFactory.createCompoundBorder(empty, xxx);
    Color crl = (Color.blue);
    Border compound1 = BorderFactory.createCompoundBorder(empty, xxx);

It's creating the file in the same directory as your script. Try this instead.

$content = "some text here";
$fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/myText.txt","wb");
fwrite($fp,$content);
fclose($fp);

This is how to pass the struct by reference. This means that your function can access the struct outside of the function and modify its values. You do this by passing a pointer to the structure to the function.

#include <stdio.h>
/* card structure definition */
struct card
{
    int face; // define pointer face
}; // end structure card

typedef struct card Card ;

/* prototype */
void passByReference(Card *c) ;

int main(void)
{
    Card c ;
    c.face = 1 ;
    Card *cptr = &c ; // pointer to Card c

    printf("The value of c before function passing = %d\n", c.face);
    printf("The value of cptr before function = %d\n",cptr->face);

    passByReference(cptr);

    printf("The value of c after function passing = %d\n", c.face);

    return 0 ; // successfully ran program
}

void passByReference(Card *c)
{
    c->face = 4;
}

This is how you pass the struct by value so that your function receives a copy of the struct and cannot access the exterior structure to modify it. By exterior I mean outside the function.

#include <stdio.h>


/* global card structure definition */
struct card
{
    int face ; // define pointer face
};// end structure card

typedef struct card Card ;

/* function prototypes */
void passByValue(Card c);

int main(void)
{
    Card c ;
    c.face = 1;

    printf("c.face before passByValue() = %d\n", c.face);

    passByValue(c);

    printf("c.face after passByValue() = %d\n",c.face);
    printf("As you can see the value of c did not change\n");
    printf("\nand the Card c inside the function has been destroyed"
        "\n(no longer in memory)");
}


void passByValue(Card c)
{
    c.face = 5;
}

The character is a backslash \

From the bash manual:

The backslash character ‘\’ may be used to remove any special meaning for the next character read and for line continuation.

Ok I realised that you can do this:

1. In Xcode > Window > Devices, select a connected iPhone/iPad/etc top left.
2. View Device Logs
3. All Logs

You probably have a lot of logs there, and to make it easier to find your imported log later, you could just go ahead and delete all logs at this point... unless they mean money to you. Or unless you know the exact point of time the crash happened - it should be written in the file anyway... I'm lazy so I just delete all old logs (this actually took a while).

4. Just drag and drop your file into that list. It worked for me.

https://github.com/logary/logary/blob/master/src/Logary/DataModel.fs#L832-L837

let scaleBytes (value : float) : float * string =
    let log2 x = log x / log 2.
    let prefixes = [| ""; "Ki"; "Mi"; "Gi"; "Ti"; "Pi" |] // note the capital K and the 'i'
    let index = int (log2 value) / 10
    1. / 2.**(float index * 10.),
sprintf "%s%s" prefixes.[index] (Units.symbol Bytes)

(DISCLAIMER: I wrote this code, even the code in the link!)

This is the best thing I've found so far - shows you the symlinks in the current directory, recursively, but without following them, displayed with full paths and other information:

find ./ -type l -print0 | xargs -0 ls -plah

outputs looks about like this:

lrwxrwxrwx 1 apache develop 99 Dec  5 12:49 ./dir/dir2/symlink1 -> /dir3/symlinkTarget
lrwxrwxrwx 1 apache develop 81 Jan 10 14:02 ./dir1/dir2/dir4/symlink2 -> /dir5/whatever/symlink2Target
etc...

DataGridView.SelectedCells is a collection of cells, so it's not as simple as calling ToString() on it. You have to loop through each cell in the collection and get each cell's value instead.

The following will create a comma-delimited list of all selected cells' values.

C#

TextBox1.Text = "";
bool FirstValue = true;
foreach(DataGridViewCell cell in DataGridView1.SelectedCells)
{
    if(!FirstValue)
    {
        TextBox1.Text += ", ";
    }
    TextBox1.Text += cell.Value.ToString();
    FirstValue = false;
}

VB.NET (Translated from the code above)

TextBox1.Text = ""
Dim FirstValue As Boolean =  True 
Dim cell As DataGridViewCell
For Each cell In DataGridView1.SelectedCells
    If Not FirstValue Then
        TextBox1.Text += ", "
    End If
    TextBox1.Text += cell.Value.ToString()
    FirstValue = False
Next

Just different names for what is really ECMAScript. John Resig has a good explanation.

Here's the full version breakdown:

• IE 6-7 support JScript 5 (which is equivalent to ECMAScript 3, JavaScript 1.5)
• IE 8 supports JScript 6 (which is equivalent to ECMAScript 3, JavaScript 1.5 - more bug fixes over JScript 5)
• Firefox 1.0 supports JavaScript 1.5 (ECMAScript 3 equivalent)
• Firefox 1.5 supports JavaScript 1.6 (1.5 + Array Extras + E4X + misc.)
• Firefox 2.0 supports JavaScript 1.7 (1.6 + Generator + Iterators + let + misc.)
• Firefox 3.0 supports JavaScript 1.8 (1.7 + Generator Expressions + Expression Closures + misc.)
• The next version of Firefox will support JavaScript 1.9 (1.8 + To be determined)
• Opera supports a language that is equivalent to ECMAScript 3 + Getters and Setters + misc.
• Safari supports a language that is equivalent to ECMAScript 3 + Getters and Setters + misc.

Try:

UPDATE Dispatch_Post

It depends on your file path. For me, the current directory was [project]\bin\Debug, so I had to move to the parent folder twice.

Image image = Image.FromFile(@"..\..\Pictures\"+text+".png");
this.pictureBox1.Image = image;

To find your current directory, you can make a dummy label called label2 and write this:

this.label2.Text = System.IO.Directory.GetCurrentDirectory();

As a setter, how about:

// setter
public void beCurrent(boolean X) {
    this.isCurrent = X;
}

or

// setter
public void makeCurrent(boolean X) {
    this.isCurrent = X;
}

I'm not sure if these naming make sense to native English speakers.

Have a look at iconv() or mb_convert_encoding(). Just by the way: why don't utf8_encode() and utf8_decode() work for you?

utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1

utf8_encode — Encodes an ISO-8859-1 string to UTF-8

So essentially

$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');

$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');

all should do the same - with utf8_en/decode() requiring no special extension, mb_convert_encoding() requiring ext/mbstring and iconv() requiring ext/iconv.

Short answer

Why? Because there is still whitespace (carriage returns, tabs, spaces, newline) left in the input stream.

When? When you are using some function which does not on their own ignores the leading whitespaces. Cin by default ignores and removes the leading whitespace but getline does not ignore the leading whitespace on its own.

Now a detailed answer.

Everything you input in the console is read from the standard stream stdin. When you enter something, let's say 256 in your case and press enter, the contents of the stream become 256\n. Now cin picks up 256 and removes it from the stream and \n still remaining in the stream. Now next when you enter your name, let's say Raddicus, the new contents of the stream is \nRaddicus.

Now here comes the catch. When you try to read a line using getline, if not provided any delimiter as the third argument, getline by default reads till the newline character and removes the newline character from the stream. So on calling new line, getline reads and discards \n from the stream and resulting in an empty string read in mystr which appears like getline is skipped (but it's not) because there was already an newline in the stream, getline will not prompt for input as it has already read what it was supposed to read.

Now, how does cin.ignore help here?

According to the ignore documentation extract from cplusplus.com-

istream& ignore (streamsize n = 1, int delim = EOF);

Extracts characters from the input sequence and discards them, until either n characters have been extracted, or one compares equal to delim.

The function also stops extracting characters if the end-of-file is reached. If this is reached prematurely (before either extracting n characters or finding delim), the function sets the eofbit flag.

So, cin.ignore(256, '\n');, ignores first 256 characters or all the character untill it encounters delimeter (here \n in your case), whichever comes first (here \n is the first character, so it ignores until \n is encountered).

Just for your reference, If you don't exactly know how many characters to skip and your sole purpose is to clear the stream to prepare for reading a string using getline or cin you should use cin.ignore(numeric_limits<streamsize>::max(),'\n').

Quick explanation: It ignores the characters equal to maximum size of stream or until a '\n' is encountered, whichever case happens first.

Try this

SELECT YEAR(end_date)*12 + MONTH(end_date) - (YEAR(start_date)*12 + MONTH(start_date))

Create a method that returns all digits, and another that counts them:

public static int GetNumberOfDigits(this long value)
{
    return value.GetDigits().Count();
}

public static IEnumerable<int> GetDigits(this long value)
{
    do
    {
        yield return (int)(value % 10);
        value /= 10;
    } while (value != 0);
}

This felt like the more intuitive approach to me when tackling this problem. I tried the Log10 method first due to its apparent simplicity, but it has an insane amount of corner cases and precision problems.

I also found the if-chain proposed in the other answer to a bit ugly to look at.

I know this is not the most efficient method, but it gives you the other extension to return the digits as well for other uses (you can just mark it private if you don't need to use it outside the class).

Keep in mind that it does not consider the negative sign as a digit.

As cardern has said list will do the job.

Here is how you can use a named range.

Select your range and enter a new name:

Select your cell that you want a drop down to be in and goto data tab -> data validation.

Select 'List' from the 'Allow' Drop down menu.

Enter your named range like this:

Now you have a drop down linked to your range. If you insert new rows in your range everything will update automatically.

A shorter alternative to the previously mentioned stash approach would be:

Temporarily move the changes to a stash.

1. git stash

Create and switch to a new branch and then pop the stash to it in just one step.

2. git stash branch new_branch_name

Then just add and commit the changes to this new branch.

Answer given by kennyut/Kistian works very well but to get exact RDD like output when RDD consist of list of attributes e.g. [1,2,3,4] we can use flatmap command as below,

rdd = df.rdd.flatMap(list)
or 
rdd = df.rdd.flatmap(lambda x: list(x))

The standard Python library module random has what you want:

normalvariate(mu, sigma)
Normal distribution. mu is the mean, and sigma is the standard deviation.

For the algorithm itself, take a look at the function in random.py in the Python library.

When entering the script's full file spec or its filename on the command line, the shell will use information accessibly by

assoc | grep -i vbs
.vbs=VBSFile

ftype | grep -i vbs
VBSFile=%SystemRoot%\System32\CScript.exe "%1" %*

to decide which program to run for the script. In my case it's cscript.exe, in yours it will be wscript.exe - that explains why your WScript.Echos result in MsgBoxes.

As

cscript /?
Usage: CScript scriptname.extension [option...] [arguments...]

Options:
 //B         Batch mode: Suppresses script errors and prompts from displaying
 //D         Enable Active Debugging
 //E:engine  Use engine for executing script
 //H:CScript Changes the default script host to CScript.exe
 //H:WScript Changes the default script host to WScript.exe (default)
 //I         Interactive mode (default, opposite of //B)
 //Job:xxxx  Execute a WSF job
 //Logo      Display logo (default)
 //Nologo    Prevent logo display: No banner will be shown at execution time
 //S         Save current command line options for this user
 //T:nn      Time out in seconds:  Maximum time a script is permitted to run
 //X         Execute script in debugger
 //U         Use Unicode for redirected I/O from the console

shows, you can use //E and //S to permanently switch your default host to cscript.exe.

If you are so lazy that you don't even want to type the extension, make sure that the PATHEXT environment variable

set | grep -i vbs
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.py;.pyw;.tcl;.PSC1

contains .VBS and there is no Converter.cmd (that converts your harddisk into a washing machine) in your path.

Update wrt comment:

If you 'don't want to specify the full path of my vbscript everytime' you may:

1. put your CONVERTER.VBS in a folder that is included in the PATH environment variable; the shell will then search all pathes - if necessary taking the PATHEXT and the ftype/assoc info into account - for a matching 'executable'.
2. put a CONVERTER.BAT/.CMD into a path directory that contains a line like cscript p:\ath\to\CONVERTER.VBS

In both cases I would type out the extension to avoid (nasty) surprises.

You can use bootstrap tooltip. Do not forget to initialize it.

<span class="tooltip-r" data-toggle="tooltip" data-placement="left" title="Explanation">

Will be shown text Explanation on the left side.

and run it with js:

$('.tooltip-r').tooltip();

How about this, replacing @ with $:

$("body").children().each(function () {

Use the Soot Java Optimization framework to directly modify the bytecode. http://www.sable.mcgill.ca/soot/

Soot is completely written in Java and works with new Java versions.

Firstly run this query

SHOW VARIABLES LIKE '%char%';

You have character_set_server='latin1'

If so,go into your config file,my.cnf and add or uncomment these lines:

character-set-server = utf8
collation-server = utf8_unicode_ci

Restart the server. Yes late to the party,just encountered the same issue.

Option 1 You can set a Slack channel to automatically delete messages after 1 day, but it's a little hidden. First, you have to go to your Slack Workspace Settings, Message Retention & Deletion, and check "Let workspace members override these settings". After that, in the Slack client you can open a channel, click the gear, and click "Edit message retention..."

Option 2 The slack-cleaner command line tool that others have mentioned.

Option 3 Below is a little Python script that I use to clear Private channels. Can be a good starting point if you want more programmatic control of deletion. Unfortunately Slack has no bulk-delete API, and they rate-limit the individual delete to 50 per minute, so it unavoidably takes a long time.

Note, that script will need modification to list & clear public channels. The API methods for those are channels.* instead of groups.*

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

Why should you learn Python Programming Language?

Python offers a stepping stone into the world of programming. Even though Python Programming Language has been around for 25 years, it is still rising in popularity. Some of the biggest advantage of Python are it's

• Easy to Read & Easy to Learn
• Very productive or small as well as big projects
• Big libraries for many things

What is Python Programming Language used for?

As a general purpose programming language, Python can be used for multiple things. Python can be easily used for small, large, online and offline projects. The best options for utilizing Python are web development, simple scripting and data analysis. Below are a few examples of what Python will let you do:

Web Development:

You can use Python to create web applications on many levels of complexity. There are many excellent Python web frameworks including, Pyramid, Django and Flask, to name a few.

Data Analysis:

Python is the leading language of choice for many data scientists. Python has grown in popularity, within this field, due to its excellent libraries including; NumPy and Pandas and its superb libraries for data visualisation like Matplotlib and Seaborn.

Machine Learning:

What if you could predict customer satisfaction or analyse what factors will affect household pricing or to predict stocks over the next few days, based on previous years data? There are many wonderful libraries implementing machine learning algorithms such as Scikit-Learn, NLTK and TensorFlow.

Computer Vision:

You can do many interesting things such as Face detection, Color detection while using Opencv and Python.

Internet Of Things With Raspberry Pi:

Raspberry Pi is a very tiny and affordable computer which was developed for education and has gained enormous popularity among hobbyists with do-it-yourself hardware and automation. You can even build a robot and automate your entire home. Raspberry Pi can be used as the brain for your robot in order to perform various actions and/or react to the environment. The coding on a Raspberry Pi can be performed using Python. The Possibilities are endless!

Game Development:

Create a video game using module Pygame. Basically, you use Python to write the logic of the game. PyGame applications can run on Android devices.

Web Scraping:

If you need to grab data from a website but the site does not have an API to expose data, use Python to scraping data.

Writing Scripts:

If you're doing something manually and want to automate repetitive stuff, such as emails, it's not difficult to automate once you know the basics of this language.

Browser Automation:

Perform some neat things such as opening a browser and posting a Facebook status, you can do it with Selenium with Python.

GUI Development:

Build a GUI application (desktop app) using Python modules Tkinter, PyQt to support it.

Rapid Prototyping:

Python has libraries for just about everything. Use it to quickly built a (lower-performance, often less powerful) prototype. Python is also great for validating ideas or products for established companies and start-ups alike.

Python can be used in so many different projects. If you're a programmer looking for a new language, you want one that is growing in popularity. As a newcomer to programming, Python is the perfect choice for learning quickly and easily.

If you have the HTML

<form name="formname" .... id="form-first">
    <iframe id="one" src="iframe2.html">
    </iframe>
</form>

and JavaScript

function iframeRef( frameRef ) {
    return frameRef.contentWindow
        ? frameRef.contentWindow.document
        : frameRef.contentDocument
}

var inside = iframeRef( document.getElementById('one') )

inside is now a reference to the document, so you can do getElementsByTagName('textarea') and whatever you like, depending on what's inside the iframe src.

Go to Build option on the top bar of android studio>create 'Build APK(s)', once build has created, open the folder where it has available(app\build\outputs\apk) then close the folder, that's all....then try to install the app.

If you try to count the number of rows in the already autofiltered range like this:

Rowz = rnData.SpecialCells(xlCellTypeVisible).Rows.Count

It will only count the number of rows in the first contiguous visible area of the autofiltered range. E.g. if the autofilter range is rows 1 through 10 and rows 3, 5, 6, 7, and 9 are filtered, four rows are visible (rows 2, 4, 8, and 10), but it would return 2 because the first contiguous visible range is rows 1 (the header row) and 2.

A more accurate alternative is this (assuming that ws contains the worksheet with the filtered data):

Rowz = ws.AutoFilter.Range.Columns(1).SpecialCells(xlCellTypeVisible).Cells.Count - 1

We have to subtract 1 to remove the header row. We need to include the header row in our counted range because SpecialCells will throw an error if no cells are found, which we want to avoid.

The Cells property will give you an accurate count even if the Range has multiple Areas, unlike the Rows property. So we just take the first column of the autofilter range and count the number of visible cells.

Google only allows images which are coming from trusted source .

So I solved this issue by hosting my images in google drive and using its url as source for my images.

Example: with: http://drive.google.com/uc?export=view&id=FILEID'>

to form URL please refer here.

Yes, you can get all keys by using this

var redis = require('redis');
redisClient = redis.createClient(redis.port, redis.host);    
  redisClient.keys('*example*', function (err, keys) {
})

use jquery

$("#item").change(function({
    var x=$(this).val();
});

Your value will be in x variable, use this variable value in your jsp, like this {x} this statement will give the value

select charindex(  'Express',@@version)

if this value is 0 is not a express edition

mysqli_error()

As in:

$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);

Trigger error is better than die because you can use it for development AND production, it's the permanent solution.

You error clearly says, you are trying to use locale something was not there.

>>> locale.setlocale(locale.LC_ALL, 'de_DE')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

locale.Error: unsupported locale setting

To check available setting, use locale -a

deb@deb-Latitude-E7470:/ambot$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
POSIX

so you can use one among,

>>> locale.setlocale(locale.LC_ALL, 'en_AG.utf8')
'en_AG.utf8'
>>> 

for de_DE

This file can either be adjusted manually or updated using the tool, update-locale.

update-locale LANG=de_DE.UTF-8

Accurate explanation from Armin Ronacher above, expanding on his answers so that beginners like me understand it well:

Difference in the methods defined in a class, whether static or instance method(there is yet another type - class method - not discussed here so skipping it), lay in the fact whether they are somehow bound to the class instance or not. For example, say whether the method receives a reference to the class instance during runtime

class C:
    a = [] 
    def foo(self):
        pass

C # this is the class object
C.a # is a list object (class property object)
C.foo # is a function object (class property object)
c = C() 
c # this is the class instance

The __dict__ dictionary property of the class object holds the reference to all the properties and methods of a class object and thus

>>> C.__dict__['foo']
<function foo at 0x17d05b0>

the method foo is accessible as above. An important point to note here is that everything in python is an object and so references in the dictionary above are themselves pointing to other objects. Let me call them Class Property Objects - or as CPO within the scope of my answer for brevity.

If a CPO is a descriptor, then python interpretor calls the __get__() method of the CPO to access the value it contains.

In order to determine if a CPO is a descriptor, python interpretor checks if it implements the descriptor protocol. To implement descriptor protocol is to implement 3 methods

def __get__(self, instance, owner)
def __set__(self, instance, value)
def __delete__(self, instance)

for e.g.

>>> C.__dict__['foo'].__get__(c, C)

where

• self is the CPO (it could be an instance of list, str, function etc) and is supplied by the runtime
• instance is the instance of the class where this CPO is defined (the object 'c' above) and needs to be explicity supplied by us
• owner is the class where this CPO is defined(the class object 'C' above) and needs to be supplied by us. However this is because we are calling it on the CPO. when we call it on the instance, we dont need to supply this since the runtime can supply the instance or its class(polymorphism)
• value is the intended value for the CPO and needs to be supplied by us

Not all CPO are descriptors. For example

>>> C.__dict__['foo'].__get__(None, C)
<function C.foo at 0x10a72f510> 
>>> C.__dict__['a'].__get__(None, C)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'list' object has no attribute '__get__'

This is because the list class doesnt implement the descriptor protocol.

Thus the argument self in c.foo(self) is required because its method signature is actually this C.__dict__['foo'].__get__(c, C) (as explained above, C is not needed as it can be found out or polymorphed) And this is also why you get a TypeError if you dont pass that required instance argument.

If you notice the method is still referenced via the class Object C and the binding with the class instance is achieved via passing a context in the form of the instance object into this function.

This is pretty awesome since if you chose to keep no context or no binding to the instance, all that was needed was to write a class to wrap the descriptor CPO and override its __get__() method to require no context. This new class is what we call a decorator and is applied via the keyword @staticmethod

class C(object):
  @staticmethod
  def foo():
   pass

The absence of context in the new wrapped CPO foo doesnt throw an error and can be verified as follows:

>>> C.__dict__['foo'].__get__(None, C)
<function foo at 0x17d0c30>

Use case of a static method is more of a namespacing and code maintainability one(taking it out of a class and making it available throughout the module etc).

It maybe better to write static methods rather than instance methods whenever possible, unless ofcourse you need to contexualise the methods(like access instance variables, class variables etc). One reason is to ease garbage collection by not keeping unwanted reference to objects.

Actually you need to wait till the push animation ends. So you can delegate UINavigationController and prevent pushing till the animation ends.

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
    waitNavigation = NO;
}


-(void)showGScreen:(id)gvc{

    if (!waitNavigation) {
        waitNavigation = YES;
        [_nav popToRootViewControllerAnimated:NO];
        [_nav pushViewController:gvc animated:YES];
    }
}

celery 4+ celery purge command to purge all configured task queues

celery -A *APPNAME* purge

programmatically:

from proj.celery import app
app.control.purge()

all pending task will be purged. Reference: celerydoc

The reason for this error is that there are other database before the wrong operation led to the current database operation can not be carried out(i use google translation to translate my chinese to english)

There is a module called 'time' which can help you. I know two ways:

1. sleep

   Sleep (reference) asks the program to wait, and then to do the rest of the code.

   There are two ways to use sleep:

   import time # Import whole time module
   print("0.00 seconds")
   time.sleep(0.05) # 50 milliseconds... make sure you put time. if you import time!
   print("0.05 seconds")
   

   The second way doesn't import the whole module, but it just sleep.

   from time import sleep # Just the sleep function from module time
   print("0.00 sec")
   sleep(0.05) # Don't put time. this time, as it will be confused. You did
               # not import the whole module
   print("0.05 sec")
   

2. Using time since Unix time.

   This way is useful if you need a loop to be running. But this one is slightly more complex.

   time_not_passed = True
   from time import time # You can import the whole module like last time. Just don't forget the time. before to signal it.
   
   init_time = time() # Or time.time() if whole module imported
   print("0.00 secs")
   while True: # Init loop
       if init_time + 0.05 <= time() and time_not_passed: # Time not passed variable is important as we want this to run once. !!! time.time() if whole module imported :O
           print("0.05 secs")
           time_not_passed = False
   

While saying "the compiler can reserve", why rely on it? And what about automatic detection of move semantics? And what about all that repeating of the container name with the begins and ends?

Wouldn't you want something, you know, simpler?

hehe.

Now with move-data-from-rhs, append-array-to-container, append forward_list-to-container, move-container-from-lhs, thanks to @DyP's help.

Note that the above does not compile in clang thanks to the EnableFunctionIf<>... technique. In clang this workaround works.

It's said here that you should be able to add the following to your chart config:

  credits: {
    enabled: false
  },

that will remove the "Highcharts.com" text from the bottom of the chart.

Yes, although Internet Explorer 9 will compile your Javascript on a separate thread in preparation for execution on the main thread. This doesn't change anything for you as a programmer, though.

Since you don't call Num.__init__ , the field "n1" never gets created. Call it and then it will be there.

After reinstalling Android Studio, Is working without adb kill-server

Try this way..

public static HttpContext getCurrentSession()
  {
        HttpContext.Current = new HttpContext(new HttpRequest("", ConfigurationManager.AppSettings["UnitTestSessionURL"], ""), new HttpResponse(new System.IO.StringWriter()));
        System.Web.SessionState.SessionStateUtility.AddHttpSessionStateToContext(
        HttpContext.Current, new HttpSessionStateContainer("", new SessionStateItemCollection(), new HttpStaticObjectsCollection(), 20000, true,
        HttpCookieMode.UseCookies, SessionStateMode.InProc, false));
        return HttpContext.Current;
  }

The third inet_pton parameter is a pointer to an in_addr structure. After a successful inet_pton call, the in_addr structure will be populated with the address information. The structure's S_addr field contains the IP address in network byte order (reverse order).

Example : 

#include <arpa/inet.h>
uint32_t NodeIpAddress::getIPv4AddressInteger(std::string IPv4Address) {
    int result;
    uint32_t IPv4Identifier = 0;
    struct in_addr addr;
    // store this IP address in sa:
    result = inet_pton(AF_INET, IPv4Address.c_str(), &(addr));
    if (result == -1) {         
gpLogFile->Write(LOGPREFIX, LogFile::LOGLEVEL_ERROR, _T("Failed to convert IP %hs to IPv4 Address. Due to invalid family of %d. WSA Error of %d"), IPv4Address.c_str(), AF_INET, result);
    }
    else if (result == 0) {
        gpLogFile->Write(LOGPREFIX, LogFile::LOGLEVEL_ERROR, _T("Failed to convert IP %hs to IPv4"), IPv4Address.c_str());
    }
    else {
        IPv4Identifier = ntohl(*((uint32_t *)&(addr)));
    }
    return IPv4Identifier;
}

I got the same error when trying to compile a Go package on Debian 9.8:

# pkg-config --cflags  -- libssl libcrypto
Package libssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libssl.pc'

The thing is that pkg-config searches for package meta-information in .pc files. Such files come from the dev package. So, even though I had libssl installed, I still got the error. It was resolved by running:

sudo apt-get install libssl-dev

You can use the ToString overload. Have a look at this page for more info

So just Use myDate.ToString("yyyy-MM-dd HH:mm:ss")

or something equivalent

A double quote character (") can be escaped as ", but here's the rest of the story...

Double quote character must be escaped in this context:

• In XML attributes delimited by double quotes:

  <EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>
  

Double quote character need not be escaped in most contexts:

• In XML textual content:

  <NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
  

• In XML attributes delimited by single quotes ('):

  <NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
  

  Similarly, (') require no escaping if (") are used for the attribute value delimiters:

  <NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>

I would use the following awk command:

string="text,text,text,text"
char=","
awk -F"${char}" '{print NF-1}' <<< "${string}"

I'm splitting the string by $char and print the number of resulting fields minus 1.

If your shell does not support the <<< operator, use echo:

echo "${string}" | awk -F"${char}" '{print NF-1}'

This kind of code perhaps should work for You

I have tried the above solution,but in my case as suggested in the console added the property DB_CLOSE_ON_EXIT=FALSE, it fixed the issue.

 spring.datasource.url=jdbc:h2:mem:testdb;DATABASE_TO_UPPER=false;DB_CLOSE_ON_EXIT=FALSE

Sorry to jump on this question late in the game but I have an answer for irregular (non-rectangular) shapes. I solved it using SVGs to generate masks of where I want to have the event attached.

The idea is to attach events to inlined SVGs, super cheap and even user friendly because there are plenty of programs for generating SVGs. The SVG can have a layer of the image as a background.

It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.

Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.

DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj

...

The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.

var DyObjectsList = new List<dynamic>; 
if (condition1) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = true; 
    DyObj.Message = "Message 1"; 
    DyObjectsList .Add(DyObj); 
} 
if (condition2) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = false; 
    DyObj.Message = "Message 2"; 
    DyObjectsList .Add(DyObj); 
} 

your resulting List essentially looks like this

DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj

Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.

However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.

Try using RUN /bin/sh instead of bash.

There are a few encodings that can be used to de-/encode from str to str or from unicode to unicode. For example base64, hex or even rot13. They are listed in the codecs module.

Edit:

The decode message on a unicode string can undo the corresponding encode operation:

In [1]: u'0a'.decode('hex')
Out[1]: '\n'

The returned type is str instead of unicode which is unfortunate in my opinion. But when you are not doing a proper en-/decode between str and unicode this looks like a mess anyway.

If you need to organize data in columns of 1 / 2 / 4 depending of the viewport size then push and pull may be no option at all. No matter how you order your items in the first place, one of the sizes may give you a wrong order.

A solution in this case is to use nested rows and cols without any push or pull classes.

Example

In XS you want...

A
B
C
D
E
F
G
H

In SM you want...

A   E
B   F
C   G
D   H

In MD and above you want...

A   C   E   G
B   D   F   H

Solution

Use nested two-column child elements in a surrounding two-column parent element:

Here is a working snippet:

<script src="https://code.jquery.com/jquery-1.12.4.min.js" type="text/javascript" ></script>_x000D_
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"> _x000D_
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>_x000D_
_x000D_
<div class="row">_x000D_
  <div class="col-sm-6">_x000D_
    <div class="row">_x000D_
      <div class="col-md-6"><p>A</p><p>B</p></div>_x000D_
      <div class="col-md-6"><p>C</p><p>D</p></div>_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="col-sm-6">_x000D_
    <div class="row">_x000D_
      <div class="col-md-6"><p>E</p><p>F</p></div>_x000D_
      <div class="col-md-6"><p>G</p><p>H</p></div>_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Another beauty of this solution is, that the items appear in the code in their natural order (A, B, C, ... H) and don't have to be shuffled, which is nice for CMS generation.

Python is not strongly typed in the sense of static or compile-time type checking.

Most Python code falls under so-called "Duck Typing" -- for example, you look for a method read on an object -- you don't care if the object is a file on disk or a socket, you just want to read N bytes from it.

Pojo - Plain old java object

pojo class is an ordinary class without any specialties,class totally loosely coupled from technology/framework.the class does not implements from technology/framework and does not extends from technology/framework api that class is called pojo class.

pojo class can implements interfaces and extend classes but the super class or interface should not be an technology/framework.

Examples :

1.

class ABC{
----
}

ABC class not implementing or extending from technology/framework that's why this is pojo class.

2.

class ABC extends HttpServlet{
---
}

ABC class extending from servlet technology api that's why this is not a pojo class.

3.

class ABC implements java.rmi.Remote{
----
}

ABC class implements from rmi api that's why this is not a pojo class.

4.

class ABC implements java.io.Serializable{
---
}

this interface is part of java language not a part of technology/framework.so this is pojo class.

5.

class ABC extends Thread{
--
}

here thread is also class of java language so this is also a pojo class.

6.

class ABC extends Test{
--
}

if Test class extends or implements from technologies/framework then ABC is also not a pojo class because it inherits the properties of Test class. if Test class is not a pojo class then ABC class also not a pojo class.

7.

now this point is an exceptional case

@Entity
class ABC{
--
}

@Entity is an annotation given by hibernate api or jpa api but still we can call this class as pojo class. class with annotations given from technology/framework is called pojo class by this exceptional case.

The p tag denotes a paragraph element. It has margins/padding applied to it. A span is an unstyled inline tag. An important difference is that p is a block element when span is inline, meaning that <p>Hi</p><p>There</p> would appear on different lines when <span>Hi</span><span>There</span> winds up side by side.

To use uint8_t type alias, you have to include stdint.h standard header.

body {
    width: calc( 100% );
    max-width: calc( 100vw - 1em );
}

works with default scroll bars as well. could add:

overflow-x: hidden;

to ensure horizontal scroll bars remain hidden for the parent frame. unless this is desired from your clients.

The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.

See Best Way to Embed PDF in HTML for an overview.

There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.

If you are using Babel then Unicode support is already available.

I also released a plugin which transforms your source code such that you can write regular expressions like /^\p{L}+$/. These will then be transformed into something that browsers understand.

Here is the project page of the plugin:

babel-plugin-utf-8-regex

You do not have to have the RETURN stament.

I just encountered this exception and in my case it was cause by a white space between asp:content elements

So, this failed:

<asp:content runat="server" ContentPlaceHolderID="Header">
    Header
</asp:content>

<asp:Content runat="server" ContentPlaceHolderID="Content">
    Content
</asp:Content>

But removing the white spaces between the elements worked:

<asp:content runat="server" ContentPlaceHolderID="Header">
    Header
</asp:content><asp:Content runat="server" ContentPlaceHolderID="Content">
    Content
</asp:Content>
