To expand on Karl's reply, Vim looks in a specific set of directories for its runtime files. You can see that set of directories via :set runtimepath?. In order to tell Vim to also look inside ~/.vim/vim-haml you'll want to add

set runtimepath+=$HOME/.vim/vim-haml

to your ~/.vimrc. You'll likely also want the following in your ~/.vimrc to enable all the functionality provided by vim-haml.

filetype plugin indent on
syntax on

You can refer to the 'runtimepath' and :filetype help topics in Vim for more information.

None of the above answers worked for me so let me share my experience. I am running nginx in a docker container that has a port mapping (hostPort:containerPort) - 80:80 The above answers are giving me strange console output. Only the good old 'nmap' is working flawlessly even catching the nginx version. The command working for me is:

 nmap -sV localhost -p 80

We are doing nmap using the -ServiceVersion switch on the localhost and port: 80. It works great for me.

try this css:

/* Show in default resolution screen*/
#container2 {
width: 960px;
position: relative;
margin:0 auto;
line-height: 1.4em;
}

/* If in mobile screen with maximum width 479px. The iPhone screen resolution is 320x480 px (except iPhone4, 640x960) */    
@media only screen and (max-width: 479px){
    #container2 { width: 90%; }
}

A Context is a handle to the system; it provides services like resolving resources, obtaining access to databases and preferences, and so on. It is an "interface" that allows access to application specific resources and class and information about application environment. Your activities and services also extend Context to they inherit all those methods to access the environment information in which the application is running.

This means you must have to pass context to the specific class if you want to get/modify some specific information about the resources. You can pass context in the constructor like

public classname(Context context, String s1) 
{
...
}

Try something like this:

var node=document.createElement("LI");
var textnode=document.createTextNode(firstname);
node.appendChild(textnode);
document.getElementById("demo").appendChild(node);

Sending data from formfields back to the server (php) is usualy done by the POST method which can be found back in the superglobal array $_POST inside PHP. There is no need to transform it to JSON before you send it to the server. Little example:

<?php

if($_SERVER['REQUEST_METHOD'] == 'POST')
{
    echo '<pre>';
    print_r($_POST);
}
?>
<form action="" method="post">
<input type="text" name="email" value="[email protected]" />
<button type="submit">Send!</button>

With AJAX you are able to do exactly the same thing, only without page refresh.

If Ruby is installed, then

ruby yourfile.rb

where yourfile.rb is the file containing the ruby code.

Or

irb

to start the interactive Ruby environment, where you can type lines of code and see the results immediately.

Merge commits: retains all of the commits in your branch and interleaves them with commits on the base branch

Merge Squash: retains the changes but omits the individual commits from history

Rebase: This moves the entire feature branch to begin on the tip of the master branch, effectively incorporating all of the new commits in master

More on here

import numpy as np    
x = [1,2,3,4,5]
[(np.mean((x[i],x[i+1]))) for i in range(len(x)-1)]
# [1.5, 2.5, 3.5, 4.5]

You can iterate over keys by calling map.keySet(), or iterate over the entries by calling map.entrySet(). Iterating over entries will probably be faster.

for (Map.Entry<String, List<String>> entry : map.entrySet()) {
    List<String> list = entry.getValue();
    // Do things with the list
}

If you want to ensure that you iterate over the keys in the same order you inserted them then use a LinkedHashMap.

By the way, I'd recommend changing the declared type of the map to <String, List<String>>. Always best to declare types in terms of the interface rather than the implementation.

I was able to fix this with:

html { height: 100%; }

As xanatos said, this is a misuse of ForEach.

If you are going to use linq to handle this, I would do it like this:

var departments = employees.SelectMany(x => x.Departments);
foreach (var item in departments)
{
    item.SomeProperty = null;
}
collection.AddRange(departments);

However, the Loop approach is more readable and therefore more maintainable.

A nice way is to use Spring's ResponseStatusException

Rather than returning a ResponseEntityor similar you simply throw the ResponseStatusException from the controller with an HttpStatus and cause, for example:

throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Cause description here");

or:

throw new ResponseStatusException(HttpStatus.INTERNAL_SERVER_ERROR, "Cause description here");

This results in a response to the client containing the HTTP status (e.g. 400 Bad request) with a body like:

{
  "timestamp": "2020-07-09T04:43:04.695+0000",
  "status": 400,
  "error": "Bad Request",
  "message": "Cause description here",
  "path": "/test-api/v1/search"
}

Instead of using git-revert you could have used this command in the devel branch to throw away (undo) the wrong merge commit (instead of just reverting it).

git checkout devel
git reset --hard COMMIT_BEFORE_WRONG_MERGE

This will also adjust the contents of the working directory accordingly. Be careful:

• Save your changes in the develop branch (since the wrong merge) because they too will be erased by the git-reset. All commits after the one you specify as the git reset argument will be gone!
• Also, don't do this if your changes were already pulled from other repositories because the reset will rewrite history.

I recommend to study the git-reset man-page carefully before trying this.

Now, after the reset you can re-apply your changes in devel and then do

git checkout devel
git merge 28s

This will be a real merge from 28s into devel like the initial one (which is now erased from git's history).

foo.instance_of? String

or

foo.kind_of? String 

if you you only care if it is derrived from String somewhere up its inheritance chain

document.getElementById("fName").style.border="1px solid black";

from IPython import get_ipython;   
get_ipython().magic('reset -sf')

If you need one single regex, try:

(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)

A short explanation:

(?=.*[a-z])        // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z])        // use positive look ahead to see if at least one upper case letter exists
(?=.*\d)           // use positive look ahead to see if at least one digit exists
(?=.*\W])        // use positive look ahead to see if at least one non-word character exists

And I agree with SilentGhost, \W might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?] (feel free to add more of course!)

Terminology

First, let's get some terminology out of the way...

upstream <= The remote git repo (likely whose master or release branch is in production)

forked-repo <= The remote [experimental git repo] (https://docs.github.com/en/github/getting-started-with-github/fork-a-repo) also known as "origin".

local repo <= The files and directories that you work with on your local workstaion, which you likely got by running a git clone my-forked-repo.git command

local index <= Also known as your local git "stage", i.e., where you stage your files before pushing them to you remote repo.

Github workflow process

Next, let's talk about the process of getting your changes to the upstream repo:

The process is generally to work on a feature branch and then push said branch, and open a Pull Request, either to your forked-repo's master branch or to the upstream's master branch

Create a feature branch by running git checkout -b FEATURE_BRANCH_NAME

Add/delete/modify files project files.

Add files by running git add .

Commit your files to your index by running git commit -m'My commit message'

Push your staged files by running git push origin FEATURE_BRANCH_NAME

Solution for entirely different commit histories

The master and upstreambranch are entirely different commit histories message can occur when you've forked a git repository and have changed your git history.

For example, if you fork a repo and pull your forked repo to work on it locally...

If then you decide to rewrite the entire application and then decide it's a good idea to deleting all existing files, including the forked-repo's .git directory. You add new files and directories to recreate your app and also recreate your .git directory with git init command.

Now, your application works great with your new files and you want to get it merged into the upstream repo. However, when you push your changes you get that "...entirely different commit histories..." error message.

You'll see that your original git commit will be different in your new local directory and if in your remote fork (as well as your upstream). Check this out by running this command in your current directory: git log --reverse master. Then running the following: pushd $(mktemp -d); git clone https://github.com/my-forking-username/my-forked-repo.git; git log --reverse master; popd

You must fix your local .git repo to match your remote my-forked-repo if you want to push your commits and subsequently perform a pull request (in hopes of merging your new updates to the upstream/master branch).

git clone https://github.com/my-forking-username/my-forked-repo.git
cd my-forked-repo
git checkout -b my-new-files-branch-name
# Delete all files and directories except for the .git directory
git add .
git commit -m'Remove old files'
# Copy your new files to this my-forked-repo directory
git add .
git commit -m'Add new files'
git push origin my-new-files-branch-name

Create a PR on GitHub and request to merge your my-new-files-branch-name branch in your my-forked-repo into master.

Note: The "...entirely different commit histories..." error message can also occur in non-forked repos for the same reasons and can be fixed with the same solution above.

You can use the jQuery ajax method link if you want to pass data from client to server. In this case you can use $_SERVER['HTTP_USER_AGENT'] variable to found browser user agent.

This is what a constant expression in Java looks like:

package com.mycompany.mypackage;

public class MyLinks {
  // constant expression
  public static final String GUESTBOOK_URL = "/guestbook";
}

You can use it with annotations as following:

import com.mycompany.mypackage.MyLinks;

@WebServlet(urlPatterns = {MyLinks.GUESTBOOK_URL})
public class GuestbookServlet extends HttpServlet {
  // ...
}

Sure you could write that:

public static class Utils {
    public static bool IsAny<T>(this IEnumerable<T> data) {
        return data != null && data.Any();
    }
}

however, be cautious that not all sequences are repeatable; generally I prefer to only walk them once, just in case.

We faced the same issue and changed commandname="" to modelAttribute="" in jsp page to solve this issue.

An executable jar file is just a jar file containing a Main-Class entry in its manifest. So you just need to configure the jar task in order to add this entry in its manifest:

jar {
    manifest {
        attributes 'Main-Class': 'com.foo.bar.MainClass'
    }
}

You might also need to add classpath entries in the manifest, but that would be done the same way.

See http://docs.oracle.com/javase/tutorial/deployment/jar/manifestindex.html

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

I'm going to assume you mean carriage returns (CR, "\r", 0x0d) at the ends of lines rather than just blindly within a file (you may have them in the middle of strings for all I know). Using this test file with a CR at the end of the first line only:

$ cat infile
hello
goodbye

$ cat infile | od -c
0000000   h   e   l   l   o  \r  \n   g   o   o   d   b   y   e  \n
0000017

dos2unix is the way to go if it's installed on your system:

$ cat infile | dos2unix -U | od -c
0000000   h   e   l   l   o  \n   g   o   o   d   b   y   e  \n
0000016

If for some reason dos2unix is not available to you, then sed will do it:

$ cat infile | sed 's/\r$//' | od -c
0000000   h   e   l   l   o  \n   g   o   o   d   b   y   e  \n
0000016

If for some reason sed is not available to you, then ed will do it, in a complicated way:

$ echo ',s/\r\n/\n/
> w !cat
> Q' | ed infile 2>/dev/null | od -c
0000000   h   e   l   l   o  \n   g   o   o   d   b   y   e  \n
0000016

If you don't have any of those tools installed on your box, you've got bigger problems than trying to convert files :-)

Despite @Saint Hill's answer if you consider the time complexity of str.toCharArray(),

the first one is faster even for very large strings. You can run the code below to see it for yourself.

        char [] ch = new char[1_000_000_00];
    String str = new String(ch); // to create a large string

    // ---> from here
    long currentTime = System.nanoTime();
    for (int i = 0, n = str.length(); i < n; i++) {
        char c = str.charAt(i);
    }
    // ---> to here
    System.out.println("str.charAt(i):"+(System.nanoTime()-currentTime)/1000000.0 +" (ms)");

    /**
     *   ch = str.toCharArray() itself takes lots of time   
     */
    // ---> from here
    currentTime = System.nanoTime();
    ch = str.toCharArray();
    for (int i = 0, n = str.length(); i < n; i++) {
        char c = ch[i];
    }
    // ---> to  here
    System.out.println("ch = str.toCharArray() + c = ch[i] :"+(System.nanoTime()-currentTime)/1000000.0 +" (ms)");

output:

str.charAt(i):5.492102 (ms)
ch = str.toCharArray() + c = ch[i] :79.400064 (ms)

There is an .Offset property on a Range class which allows you to do just what you need

ActiveCell.Offset(numRows, numCols)

follow up on a comment:

Dim newRange as Range
Set newRange = Range(ActiveCell, ActiveCell.Offset(numRows, numCols))

and you can verify by MsgBox newRange.Address

and here's how to assign this range to an array

fs.readFile takes a call back which calls response.send as you have shown - good. If you simply replace that with fs.readFileSync, you need to be aware it does not take a callback so your callback which calls response.send will never get called and therefore the response will never end and it will timeout.

You need to show your readFileSync code if you're not simply replacing readFile with readFileSync.

Also, just so you're aware, you should never call readFileSync in a node express/webserver since it will tie up the single thread loop while I/O is performed. You want the node loop to process other requests until the I/O completes and your callback handling code can run.

Sorry guys.. maybe it's a bit late.. I've been using NoGray.. it's cool..

OK, here is what I did to fix the problem:

Open Eclipse. Then:
  Window > Android SDK and AVD Manager

       + Android SDK Platform-tools, revision 1

[Install Selected]

Open your file in Notepad++. From the Encoding menu, select Convert to UTF-8 without BOM, save the file, replace the old file with this new file. And it will work, damn sure.

Got the same question from a friend. My suggestion which does not require !Important looks like this: I add a custom class "no-border" which can be added to the bootstrap table.

.table.no-border tr td, .table.no-border tr th {
  border-width: 0;
}

You can see my go at a solution here

You can use Substring:

string b = a.Substring(0,3);

To go back to the beginning of an open file and then return the first line, do this:

my_file.seek(0)
first_line = my_file.readline()

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

var isInt = function (n) { return n === (n | 0); };

Haven't had a case where this didn't do the job.

range is expecting an integer argument, from which it will build a range of integers:

>>> range(10)
range(0, 10)
>>> list(range(10))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>>

Moreover, giving it a list will raise a TypeError because range will not know how to handle it:

>>> range([1, 2, 3])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'list' object cannot be interpreted as an integer
>>>

If you want to access the items in myList, loop over the list directly:

for i in myList:
    ...

Demo:

>>> myList = [1, 2, 3]
>>> for i in myList:
...     print(i)
...
1
2
3
>>>

You can use this command:

links https://www.honeymovies.com

Another solution is to use a RangeValidator where you set Type="Integer" like this:

<asp:RangeValidator runat="server"
    id="valrNumberOfPreviousOwners"
    ControlToValidate="txtNumberOfPreviousOwners"
    Type="Integer"
    MinimumValue="0"
    MaximumValue="999"
    CssClass="input-error"
    ErrorMessage="Please enter a positive integer."
    Display="Dynamic">
</asp:RangeValidator>

You can set reasonable values for the MinimumValue and MaximumValue attributes too.

Use -F [field separator] to split the lines on "s:

awk -F '"' '{print $2}' your_input_file

or for input from pipe

<some_command> | awk -F '"' '{print $2}'

output:

A B
C
D

You can check if the Connected property is set to $true and display a friendly message:

    $t = New-Object Net.Sockets.TcpClient "10.45.23.109", 443 

    if($t.Connected)
    {
        "Port 443 is operational"
    }
    else
    {
        "..."
    }

This seems to have changed in the latest version of React Native when using refs to calculate.

Declare refs this way.

  <View
    ref={(image) => {
    this._image = image
  }}>

And find the value this way.

  _measure = () => {
    this._image._component.measure((width, height, px, py, fx, fy) => {
      const location = {
        fx: fx,
        fy: fy,
        px: px,
        py: py,
        width: width,
        height: height
      }
      console.log(location)
    })
  }

This is in answer to your question...

I'd also like to know how to make it open up in Sublime Text 2 instead

For Windows:

git config --global core.editor "'C:/Program Files/Sublime Text 2/sublime_text.exe'"

Check that the path for sublime_text.exe is correct and adjust if needed.

For Mac/Linux:

git config --global core.editor "subl -n -w"

If you get an error message such as:

error: There was a problem with the editor 'subl -n -w'.

Create the alias for subl

sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl

Again check that the path matches for your machine.

For Sublime Text simply save cmd S and close the window cmd W to return to git.

break and continue breaks the readability for the reader, although it's often useful. Not as much as "goto" concept, but almost.

Besides, if you take some new languages like Scala (inspired by Java and functional programming languages like Ocaml), you will notice that break and continue simply disappeared.

Especially in functional programming, this style of code is avoided:

Why scala doesn't support break and continue?

To sum up: break and continueare widely used in Java for an imperative style, but for any coders that used to practice functional programming, it might be.. weird.

Ideally you would use str.find or str.index like demented hedgehog said. But you said you can't ...

Your problem is your code searches only for the first character of your search string which(the first one) is at index 2.

You are basically saying if char[0] is in s, increment index until ch == char[0] which returned 3 when I tested it but it was still wrong. Here's a way to do it.

def find_str(s, char):
    index = 0

    if char in s:
        c = char[0]
        for ch in s:
            if ch == c:
                if s[index:index+len(char)] == char:
                    return index

            index += 1

    return -1

print(find_str("Happy birthday", "py"))
print(find_str("Happy birthday", "rth"))
print(find_str("Happy birthday", "rh"))

It produced the following output:

3
8
-1

This worked for me:

grep  "\bsearch_word\b"  text_file > output.txt  ## \b indicates boundaries. This is much faster.

or,

grep -w "search_word" text_file > output.txt

Reposting this here for others from the requests issue page:

Requests' does not support doing this before version 1. Subsequent to version 1, you are expected to subclass the HTTPAdapter, like so:

from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager
import ssl

class MyAdapter(HTTPAdapter):
    def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connections,
                                       maxsize=maxsize,
                                       block=block,
                                       ssl_version=ssl.PROTOCOL_TLSv1)

When you've done that, you can do this:

import requests
s = requests.Session()
s.mount('https://', MyAdapter())

Any request through that session object will then use TLSv1.

I recently had the same issue while trying to access domains using CloudFlare Origin CA.

The only way I found to workaround/avoid HSTS cert exception on Chrome (Windows build) was following the short instructions in https://support.opendns.com/entries/66657664.

The workaround:
Add to Chrome shortcut the flag --ignore-certificate-errors, then reopen it and surf to your website.

Reminder:
Use it only for development purposes.

ls | grep "^abc"  

will give you all files beginning (which is what the OP specifically required) with the substringabc.
It operates only on the current directory whereas find operates recursively into sub folders.

To use find for only files starting with your string try

find . -name 'abc'*

Here is a useful article by Michael J. Swart on the matter, which covers different patterns and antipatterns for implementing UPSERT in SQL Server:
https://michaeljswart.com/2017/07/sql-server-upsert-patterns-and-antipatterns/

It addresses associated concurrency issues (primary key violations, deadlocks) - all of the answers provided here yet are considered antipatterns in the article (except for the @Bridge solution using triggers, which is not covered there).

Here is an extract from the article with the solution preferred by the author:

Inside a serializable transaction with lock hints:

CREATE PROCEDURE s_AccountDetails_Upsert ( @Email nvarchar(4000), @Etc nvarchar(max) )
AS 
  SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
  BEGIN TRAN

    IF EXISTS ( SELECT * FROM dbo.AccountDetails WITH (UPDLOCK) WHERE Email = @Email )

      UPDATE dbo.AccountDetails
         SET Etc = @Etc
       WHERE Email = @Email;

    ELSE 

      INSERT dbo.AccountDetails ( Email, Etc )
      VALUES ( @Email, @Etc );

  COMMIT

There is no such feature in java. By using the other API you will get this feature. Like suppose we have a animal Object containing name and id. We have list object having animal objects. Now if we want to get the all the animal name which contains 'o' from list object. we can write the following query

from(animals).where("getName", contains("o")).all();

Above Query statement will list of the animals which contains 'o' alphabet in their name. More information please go through following blog. http://javaworldwide.blogspot.in/2012/09/linq-in-java.html

Compile:

gcc -ggdb3 -O0 -o main -std=c99 -Wall -Wextra -pedantic main.c -lGL -lGLU -lglut

Run with glOrtho:

./main 1

Run with glFrustrum:

./main

Tested on Ubuntu 18.10.

Schema

Ortho: camera is a plane, visible volume a rectangle:

Frustrum: camera is a point,visible volume a slice of a pyramid:

Image source.

Parameters

We are always looking from +z to -z with +y upwards:

glOrtho(left, right, bottom, top, near, far)

• left: minimum x we see
• right: maximum x we see
• bottom: minimum y we see
• top: maximum y we see
• -near: minimum z we see. Yes, this is -1 times near. So a negative input means positive z.
• -far: maximum z we see. Also negative.

Schema:

Image source.

How it works under the hood

In the end, OpenGL always "uses":

glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

If we use neither glOrtho nor glFrustrum, that is what we get.

glOrtho and glFrustrum are just linear transformations (AKA matrix multiplication) such that:

• glOrtho: takes a given 3D rectangle into the default cube
• glFrustrum: takes a given pyramid section into the default cube

This transformation is then applied to all vertexes. This is what I mean in 2D:

Image source.

The final step after transformation is simple:

• remove any points outside of the cube (culling): just ensure that x, y and z are in [-1, +1]
• ignore the z component and take only x and y, which now can be put into a 2D screen

With glOrtho, z is ignored, so you might as well always use 0.

One reason you might want to use z != 0 is to make sprites hide the background with the depth buffer.

Deprecation

glOrtho is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.

So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.

Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.

Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.

Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

Output:

The matrix for glOrtho is really simple, composed only of scaling and translation:

scalex, 0,      0,      translatex,
0,      scaley, 0,      translatey,
0,      0,      scalez, translatez,
0,      0,      0,      1

as mentioned in the OpenGL 2 docs.

The glFrustum matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho, more info at: https://gamedev.stackexchange.com/a/118848/25171

The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho and frustum operations.

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

Framebuffer seems the way to go, it will not always contain 2+ frames like mentioned by Ryan Conrad. In my case it contained only one. I guess it depends on the frame/display size.

I tried to read the framebuffer continuously but it seems to return for a fixed amount of bytes read. In my case that is (3 410 432) bytes, which is enough to store a display frame of 854*480 RGBA (3 279 360 bytes). Yes, the frame in binary outputed from fb0 is RGBA in my device. This will most likely depend from device to device. This will be important for you to decode it =)

In my device /dev/graphics/fb0 permissions are so that only root and users from group graphics can read the fb0. graphics is a restricted group so you will probably only access fb0 with a rooted phone using su command.

Android apps have the user id (uid) app_## and group id (guid) app_## .

adb shell has uid shell and guid shell, which has much more permissions than an app. You can actually check those permissions at /system/permissions/platform.xml

This means you will be able to read fb0 in the adb shell without root but you will not read it within the app without root.

Also, giving READ_FRAME_BUFFER and/or ACCESS_SURFACE_FLINGER permissions on AndroidManifest.xml will do nothing for a regular app because these will only work for 'signature' apps.

You can use:

$answer.replace(' ' , '')

or

$answer -replace " ", ""

if you want to remove all whitespace you can use:

$answer -replace "\s", ""

sophisticated error handling

If your error handling is very sophisticated and therefore might throw an error itself, it is useful to add a flag indicating if you are already in "errorHandling-Mode". Like so:

var appIsHandlingError = false;

window.onerror = function() {
    if (!appIsHandlingError) {
        appIsHandlingError = true;
        handleError();
    }
};

function handleError() {
    // graceful error handling
    // if successful: appIsHandlingError = false;
}

Otherwise you could find yourself in an infinite loop.

I want to understand the lock each transaction isolation takes on the table

For example, you have 3 concurrent processes A, B and C. A starts a transaction, writes data and commit/rollback (depending on results). B just executes a SELECT statement to read data. C reads and updates data. All these process work on the same table T.

• READ UNCOMMITTED - no lock on the table. You can read data in the table while writing on it. This means A writes data (uncommitted) and B can read this uncommitted data and use it (for any purpose). If A executes a rollback, B still has read the data and used it. This is the fastest but most insecure way to work with data since can lead to data holes in not physically related tables (yes, two tables can be logically but not physically related in real-world apps =\).
• READ COMMITTED - lock on committed data. You can read the data that was only committed. This means A writes data and B can't read the data saved by A until A executes a commit. The problem here is that C can update data that was read and used on B and B client won't have the updated data.
• REPEATABLE READ - lock on a block of SQL(which is selected by using select query). This means B reads the data under some condition i.e. WHERE aField > 10 AND aField < 20, A inserts data where aField value is between 10 and 20, then B reads the data again and get a different result.
• SERIALIZABLE - lock on a full table(on which Select query is fired). This means, B reads the data and no other transaction can modify the data on the table. This is the most secure but slowest way to work with data. Also, since a simple read operation locks the table, this can lead to heavy problems on production: imagine that T table is an Invoice table, user X wants to know the invoices of the day and user Y wants to create a new invoice, so while X executes the read of the invoices, Y can't add a new invoice (and when it's about money, people get really mad, especially the bosses).

I want to understand where we define these isolation levels: only at JDBC/hibernate level or in DB also

Using JDBC, you define it using Connection#setTransactionIsolation.

Using Hibernate:

<property name="hibernate.connection.isolation">2</property>

Where

• 1: READ UNCOMMITTED
• 2: READ COMMITTED
• 4: REPEATABLE READ
• 8: SERIALIZABLE

Hibernate configuration is taken from here (sorry, it's in Spanish).

By the way, you can set the isolation level on RDBMS as well:

• MySQL isolation level,
• SQL Server isolation level
• Informix isolation level (Personal Note: I will never forget about SET ISOLATION TO DIRTY READ sentence.)

and on and on...

Please set your form action attribute as below it will solve your problem.

<form name="addProductForm" id="addProductForm" action="javascript:;" enctype="multipart/form-data" method="post" accept-charset="utf-8">

jQuery code:

$(document).ready(function () {
    $("#addProductForm").submit(function (event) {

        //disable the default form submission
        event.preventDefault();
        //grab all form data  
        var formData = $(this).serialize();

        $.ajax({
            url: 'addProduct.php',
            type: 'POST',
            data: formData,
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function () {
                alert('Form Submitted!');
            },
            error: function(){
                alert("error in ajax form submission");
            }
        });

        return false;
    });
});

It is better to demonstrate this way

if [[ $# -eq 0 ]] ; then
    echo 'some message'
    exit 1
fi

You normally need to exit if you have too few arguments.

This is the PHP ternary operator (also known as a conditional operator) - if first operand evaluates true, evaluate as second operand, else evaluate as third operand.

Think of it as an "if" statement you can use in expressions. Can be very useful in making concise assignments that depend on some condition, e.g.

$param = isset($_GET['param']) ? $_GET['param'] : 'default';

There's also a shorthand version of this (in PHP 5.3 onwards). You can leave out the middle operand. The operator will evaluate as the first operand if it true, and the third operand otherwise. For example:

$result = $x ?: 'default';

It is worth mentioning that the above code when using i.e. $_GET or $_POST variable will throw undefined index notice and to prevent that we need to use a longer version, with isset or a null coalescing operator which is introduced in PHP7:

$param = $_GET['param'] ?? 'default';

For some reason, I get that error unless I add the "bash" clarifier. Even adding "#!/bin/bash" to the top of my entrypoint file didn't help.

ENTRYPOINT [ "bash", "entrypoint.sh" ]

As Sahil Chhabra suggested you can use @JsonFormat with proper shape on your variable. In case you would like to apply it on every BigDecimal field you have in your Dto's you can override default format for given class.

@Configuration
public class JacksonObjectMapperConfiguration {

    @Autowired
    public void customize(ObjectMapper objectMapper) {
         objectMapper
            .configOverride(BigDecimal.class).setFormat(JsonFormat.Value.forShape(JsonFormat.Shape.STRING));
    }
}

This didn't work

=IIf((CountRows("ScannerStatisticsData") = 0),False,True)

but this did and I can't really explain why

=IIf((CountRows("ScannerStatisticsData") < 1),False,True)

guess SSRS doesn't like equal comparisons as much as less than.

Its too late, but it may be simple and useful

var json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" };
var keytoFind = "key2";
var index = Object.keys(json).indexOf(keytoFind);
alert(index);

bash doesn't know boolean variables, nor does test (which is what gets called when you use [).

A solution would be:

if $myVar ; then ... ; fi

because true and false are commands that return 0 or 1 respectively which is what if expects.

Note that the values are "swapped". The command after if must return 0 on success while 0 means "false" in most programming languages.

SECURITY WARNING: This works because BASH expands the variable, then tries to execute the result as a command! Make sure the variable can't contain malicious code like rm -rf /

string Index = i;
            string FileName = "Mutton" + Index + ".xml";
            XmlDocument xmlDoc = new XmlDocument();

            var path = Path.Combine(Server.MapPath("~/Content/FilesXML"), FileName);
            xmlDoc.Load(path); // Can use xmlDoc.LoadXml(YourString);

this is the best Solution to get the path what is exactly need for now

In jQuery, the fn property is just an alias to the prototype property.

The jQuery identifier (or $) is just a constructor function, and all instances created with it, inherit from the constructor's prototype.

A simple constructor function:

function Test() {
  this.a = 'a';
}
Test.prototype.b = 'b';

var test = new Test(); 
test.a; // "a", own property
test.b; // "b", inherited property

A simple structure that resembles the architecture of jQuery:

(function() {
  var foo = function(arg) { // core constructor
    // ensure to use the `new` operator
    if (!(this instanceof foo))
      return new foo(arg);
    // store an argument for this example
    this.myArg = arg;
    //..
  };

  // create `fn` alias to `prototype` property
  foo.fn = foo.prototype = {
    init: function () {/*...*/}
    //...
  };

  // expose the library
  window.foo = foo;
})();

// Extension:

foo.fn.myPlugin = function () {
  alert(this.myArg);
  return this; // return `this` for chainability
};

foo("bar").myPlugin(); // alerts "bar"

There's one difference — which shouldn't matter — that the other answers haven't touched on, so:

There's no difference that's likely to matter, no. Yes, there is a very small difference.

If the fulfillment handler passed to then throws, the promise returned by that call to then is rejected with what was thrown.

If it returns a rejected promise, the promise returned by the call to then is resolved to that promise (and will ultimately be rejected, since the promise it's resolved to is rejected), which may introduce one extra async "tick" (one more loop in the microtask queue, to put it in browser terms).

Any code that relies on that difference is fundamentally broken, though. :-) It shouldn't be that sensitive to the timing of the promise settlement.

Here's an example:

function usingThrow(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                throw new Error(`${v} is not 42!`);
            }
            return v;
        });
}
function usingReject(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                return Promise.reject(new Error(`${v} is not 42!`));
            }
            return v;
        });
}

// The rejection handler on this chain may be called **after** the
// rejection handler on the following chain
usingReject(1)
.then(v => console.log(v))
.catch(e => console.error("Error from usingReject:", e.message));

// The rejection handler on this chain may be called **before** the
// rejection handler on the preceding chain
usingThrow(2)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

If you run that, as of this writing you get:

Error from usingThrow: 2 is not 42!
Error from usingReject: 1 is not 42!

Note the order.

Compare that to the same chains but both using usingThrow:

function usingThrow(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                throw new Error(`${v} is not 42!`);
            }
            return v;
        });
}

usingThrow(1)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

usingThrow(2)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

which shows that the rejection handlers ran in the other order:

Error from usingThrow: 1 is not 42!
Error from usingThrow: 2 is not 42!

I said "may" above because there's been some work in other areas that removed this unnecessary extra tick in other similar situations if all of the promises involved are native promises (not just thenables). (Specifically: In an async function, return await x originally introduced an extra async tick vs. return x while being otherwise identical; ES2020 changed it so that if x is a native promise, the extra tick is removed.)

Again, any code that's that sensitive to the timing of the settlement of a promise is already broken. So really it doesn't/shouldn't matter.

In practical terms, as other answers have mentioned:

• As Kevin B pointed out, throw won't work if you're in a callback to some other function you've used within your fulfillment handler — this is the biggie
• As lukyer pointed out, throw abruptly terminates the function, which can be useful (but you're using return in your example, which does the same thing)
• As Vencator pointed out, you can't use throw in a conditional expression (? :), at least not for now

Other than that, it's mostly a matter of style/preference, so as with most of those, agree with your team what you'll do (or that you don't care either way), and be consistent.

using Apache IO could be another option for copy the Stream

@RequestMapping(path = "/file/{fileId}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> downloadFile(@PathVariable(value="fileId") String fileId,HttpServletResponse response) throws Exception {

    InputStream yourInputStream = ...
    IOUtils.copy(yourInputStream, response.getOutputStream());
    response.flushBuffer();
    return ResponseEntity.ok().build();
}

It depends on what database you are using. In MySQL, you would use the "ALTER TABLE" syntax. I don't remember exactly how, but it would go something like this if you wanted to add a column called 'newcol' that was a 200 character varchar:

ALTER TABLE example ADD newCol VARCHAR(200) AFTER otherCol;

As a workaround, go to sdk installation directory and perform the following steps:

• Navigate to system-images/android-19/default
• Move everything in there to system-images/android-19/

The directory structure should look like this:

And it should work!

why not just put the ng-controller one level higher,

<body ng-controller="ProjectController">
    <div ng-view><div>

And don't set controller in the route,

.when('/', { templateUrl: "abc.html" })

it works for me.

You use the String.format() method.

In HTML 4, the type attribute is required. In my experience, all browsers will default to text/javascript if it is absent, but that behaviour is not defined anywhere. While you can in theory leave it out and assume it will be interpreted as JavaScript, it's invalid HTML, so why not add it.

In HTML 5, the type attribute is optional and defaults to text/javascript

Use <script type="text/javascript"> or simply <script> (if omitted, the type is the same). Do not use <script language="JavaScript">; the language attribute is deprecated

Ref :

and
Difference between <script> tag with type and <script> without type?

Do you need type attribute at all?

I am using HTML5- No

I am not using HTML5 - Yes

In modern JS you can simply use async/await, like:

  async function upload() {
    return new Promise((resolve, reject) => {
        $.ajax({
            url: $(this).attr('href'),
            type: 'GET',
            timeout: 30000,
            success: (response) => {
                resolve(response);
            },
            error: (response) => {
                reject(response);
            }
        })
    })
}

Then call it in an async function like:

let response = await upload();

Try the following:

int[][] multi = new int[5][10];

... which is a short hand for something like this:

int[][] multi = new int[5][];
multi[0] = new int[10];
multi[1] = new int[10];
multi[2] = new int[10];
multi[3] = new int[10];
multi[4] = new int[10];

Note that every element will be initialized to the default value for int, 0, so the above are also equivalent to:

int[][] multi = new int[][]{
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }
};

 public char lastChar(String s) {
     if (s == "" || s == null)
        return ' ';
    char lc = s.charAt(s.length() - 1);
    return lc;
}

You just need to add three file and two css links. You can either cdn's as well. Links for the js files and css files are as such :-

1. jQuery.dataTables.min.js
2. dataTables.bootstrap.min.js
3. dataTables.bootstrap.min.css
4. bootstrap-datepicker.css
5. bootstrap-datepicker.js

They are valid if you are using bootstrap in your project.

I hope this will help you. Regards, Vivek Singla

The UserManager did not work, and As @Kevin Junghans wrote,

UpdateAsync just commits the update to the context, you still need to save the context for it to commit to the database

Here is quick solution (prior to new features in ASP.net identity v2) I used in a web forms projetc. The

class AspNetUser :IdentityUser

Was migrated from SqlServerMembership aspnet_Users. And the context is defined:

public partial class MyContext : IdentityDbContext<AspNetUser>

I apologize for the reflection and synchronous code--if you put this in an async method, use await for the async calls and remove the Tasks and Wait()s. The arg, props, contains the names of properties to update.

 public static void UpdateAspNetUser(AspNetUser user, string[] props)
 {
     MyContext context = new MyContext();
     UserStore<AspNetUser> store = new UserStore<AspNetUser>(context);
     Task<AspNetUser> cUser = store.FindByIdAsync(user.Id); 
     cUser.Wait();
     AspNetUser oldUser = cUser.Result;

    foreach (var prop in props)
    {
        PropertyInfo pi = typeof(AspNetUser).GetProperty(prop);
        var val = pi.GetValue(user);
        pi.SetValue(oldUser, val);
    }

    Task task = store.UpdateAsync(oldUser);
    task.Wait();

    context.SaveChanges();
 }

Here's my EmguCV (a C# port of OpenCV) solution:

public static Image<TColor, TDepth> Rotate90<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    var rot = new Image<TColor, TDepth>(img.Height, img.Width);
    CvInvoke.cvTranspose(img.Ptr, rot.Ptr);
    rot._Flip(FLIP.HORIZONTAL);
    return rot;
}

public static Image<TColor, TDepth> Rotate180<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    var rot = img.CopyBlank();
    rot = img.Flip(FLIP.VERTICAL);
    rot._Flip(FLIP.HORIZONTAL);
    return rot;
}

public static void _Rotate180<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    img._Flip(FLIP.VERTICAL);
    img._Flip(FLIP.HORIZONTAL);
}

public static Image<TColor, TDepth> Rotate270<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    var rot = new Image<TColor, TDepth>(img.Height, img.Width);
    CvInvoke.cvTranspose(img.Ptr, rot.Ptr);
    rot._Flip(FLIP.VERTICAL);
    return rot;
}

Shouldn't be too hard to translate it back into C++.

As suggeseted, the way to go is valgrind. It's a profiler that checks many aspects of the running performance of your application, including the usage of memory.

Running your application through Valgrind will allow you to verify if you forget to release memory allocated with malloc, if you free the same memory twice etc.

Had the same problem (is not a method) with jQuery when working on autocomplete. It appeared the code was executed before the autocomplete.js was loaded. So make sure the ui.colorpicker.js is loaded before calling colorpicker.

here's what six is:

pip search six
six                       - Python 2 and 3 compatibility utilities

to install:

pip install six

though if you did install python-dateutil from pip six should have been set as a dependency.

N.B.: to install pip run easy_install pip from command line.

Ok, I know there is an accepted answer but… for more special cases you also could use this one:

array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);

Or in a more un-complex way:

function printItem($n){
    echo $n['filename'];
    echo $n['filepath'];
}

array_map('printItem', $array);

This will allow you to manipulate the data in an easier way.

This may work:

nvm install NEW_VERSION --reinstall-packages-from=OLD_VERSION

For example:

nvm install 6.7 --reinstall-packages-from=6.4

then, if you want, you can delete your previous version with:

nvm uninstall OLD_VERSION

Where, in your case, NEW_VERSION = 5.4 OLD_VERSION = 5.0

Alternatively, try:

nvm install stable --reinstall-packages-from=current

All the above examples will actually REPLACE any params already present for the View, which may not be desired. The below code will just extend the existing params, without replacing them:

ImageView myImage = (ImageView) findViewById(R.id.image_view);
MarginLayoutParams marginParams = (MarginLayoutParams) image.getLayoutParams();
marginParams.setMargins(left, top, right, bottom);

You can use jmap to get a dump of any process running, assuming you know the pid.

Use Task Manager or Resource Monitor to get the pid. Then

jmap -dump:format=b,file=cheap.hprof <pid>

to get the heap for that process.

For me, I had to have OpenCV (3.4.2), Py-OpenCV (3.4.2), LibOpenCV (3.4.2).

My Python was version 3.5.6 with Anaconda in Windows OS 10.

In response to comments on rexem's answer, with respect to whether a an inline view or CTE would be faster I recast the queries to use a table I, and everyone, had available: sys.objects.

WITH object_rows AS (
    SELECT object_id, 
        ROW_NUMBER() OVER ( ORDER BY object_id) RN
    FROM sys.objects)
SELECT object_id
FROM object_rows
WHERE RN > 1

SELECT object_id
FROM (SELECT object_id, 
        ROW_NUMBER() OVER ( ORDER BY object_id) RN
    FROM sys.objects) T
WHERE RN > 1

The query plans produced were exactly the same. I would expect in all cases, the query optimizer would come up with the same plan, at least in simple replacement of CTE with inline view or vice versa.

Of course, try your own queries on your own system to see if there is a difference.

Also, row_number() in the where clause is a common error in answers given on Stack Overflow. Logicaly row_number() is not available until the select clause is processed. People forget that and when they answer without testing the answer, the answer is sometimes wrong. (A charge I have myself been guilty of.)

I changed the import sequence without fixing the problem, until finally I installed moments and tempus dominius (Core and bootrap), using npm and include them in boostrap.js

try {
window.Popper = require('popper.js').default;
window.$ = window.jQuery = require('jquery');
require('moment'); /*added*/
require('bootstrap');
require('tempusdominus-bootstrap-4');/*added*/} catch (e) {}

To download and show PDF files, a very similar code snipped is like below:

  private downloadFile(data: Response): void {
    let blob = new Blob([data.blob()], { type: "application/pdf" });
    let url = window.URL.createObjectURL(blob);
    window.open(url);
  }

  public showFile(fileEndpointPath: string): void {
    let reqOpt: RequestOptions = this.getAcmOptions();  //  getAcmOptions is our helper method. Change this line according to request headers you need.
    reqOpt.responseType = ResponseContentType.Blob;
    this.http
      .get(fileEndpointPath, reqOpt)
      .subscribe(
        data => this.downloadFile(data),
        error => alert("Error downloading file!"),
        () => console.log("OK!")
      );
  }

select * from tablename order by ID DESC

that will give you row with id 22

The script webpack-dev-server is already installed inside ./node_modules directory. You can either install it again globally by

sudo npm install -g webpack-dev-server

or run it like this

./node_modules/webpack-dev-server/bin/webpack-dev-server.js -d --config webpack.dev.config.js --content-base public/ --progress --colors

. means look it in current directory.

You can do

$result = Model::where(...)->count(); 

to count the results.

You can also use

if ($result->isEmpty()){}

to check whether or not the result is empty.

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

tl;dr

LocalDateTime.parse(                            // Lacking an offset or time zone, parse as a `LocalDateTime`. *Not* a specific moment in time.
    "2008-01-01 13:15:00".replace( " " , "T" )  // Alter input string to comply with ISO 8601 standard format.
)
.toLocalDate()                                  // Extract a date-only value.
.atStartOfDay(                                  // Do not assume the day starts at 00:00:00. Let class determine start-of-day.
    ZoneId.of( "Europe/Paris" )                 // Determining a specific start-of-day requires a time zone.
)                                               // Result is a `ZonedDateTime` object. At this point we have a specific moment in time, a point on the timeline.
.toString()                                     // Generate a String in standard ISO 8601 format, wisely extended to append the name of the time zone in square brackets.

2008-01-01T00:00+01:00[Europe/Paris]

To generate a String in your desired format, pass a DateTimeFormatter.

LocalDateTime.parse(                            // Lacking an offset or time zone, parse as a `LocalDateTime`. *Not* a specific moment in time.
    "2008-01-01 13:15:00".replace( " " , "T" )  // Alter input string to comply with ISO 8601 standard format.
)
.toLocalDate()                                  // Extract a date-only value.
.atStartOfDay(                                  // Do not assume the day starts at 00:00:00. Let class determine start-of-day.
    ZoneId.of( "Europe/Paris" )                 // Determining a specific start-of-day requires a time zone.
)                                               // Result is a `ZonedDateTime` object. At this point we have a specific moment in time, a point on the timeline.
.format(                                        // Generate a String representing the object’s value.
    DateTimeFormatter.ISO_LOCAL_DATE_TIME       // Built-in predefined formatter close to what you want. 
)
.replace( "T" , " " )                           // Replace the standard’s use of a 'T' in the middle with your desired SPACE character.

Details

Other Answers are correct, but use old date-time classes now outmoded by the java.time framework.

java.time

The java.time framework is built into Java 8 and later. Much of the java.time functionality is back-ported to Java 6 & 7 (ThreeTen-Backport) and further adapted to Android (ThreeTenABP).

First alter the input string to comply with the canonical version of ISO 8601 format. The standard ISO 8601 formats are used by default in java.time classes for parsing/generating strings that represent date-time values. We need to replace that SPACE in the middle with a T.

String input = "2008-01-01 13:15:00".replace( " " , "T" );  // ? 2008-01-01T13:15:00

Now we can parse it as a LocalDateTime, where “Local” means no specific locality. The input lacks any offset-from-UTC or time zone info.

LocalDateTime ldt = LocalDateTime.parse( input );

ldt.toString()… 2008-01-01T13:15:00

If you do not care about time-of-day nor time zone, then convert to a LocalDate.

LocalDate ld = ldt.toLocalDate();

ld.toString()… 2008-01-01

First Moment Of Day

If instead you want the time-of-day set to the first moment of the day, use a ZonedDateTime class, then convert to a LocalDate object to call its atStartOfDay method. Be aware that the first moment may not be the time 00:00:00 because of Daylight Saving Time or perhaps other anomalies.

The time zone is crucial because for any given moment the date varies around the world by zone. For example, a few moments after midnight in Paris is a new day for Parisians but is still “yesterday” in Montréal for the Canadians.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ldt.atZone( zoneId );
LocalDate ldFromZdt = zdt.toLocalDate();
ZonedDateTime zdtStartOfDay = ldFromZdt.atStartOfDay( zoneId );

zdtStartOfDay.toString()… 2008-01-01T00:00:00-05:00[America/Montreal]

UTC

To see that moment through the lens of the UTC time zone, extract a Instant object. Both the ZonedDateTime and Instant will represent the same moment on the timeline but appear as two different wall-clock times.

An Instant is the basic building-block class in java.time, always in UTC by definition. Use this class frequently, as you should generally be doing your business logic, data storage, and data exchange in UTC.

Instant instant = zdtStartOfDay.toInstant();

instant.toString()… 2008-01-01T05:00:00Z

We see 5 AM rather than stroke-of-midnight. In standard format, the Z on the end is short for Zulu and means “UTC”.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

htaccess files affect the directory they are placed in and all sub-directories, that is an htaccess file located in your root directory (yoursite.com) would affect yoursite.com/content, yoursite.com/content/contents, etc.

You can bulk import all aliases from one keystore to another:

keytool -importkeystore -srckeystore source.jks -destkeystore dest.jks

For a cross browser implementation I'd sugguest you look at prototype.js $A function

copyed from 1.6.1:

function $A(iterable) {
  if (!iterable) return [];
  if ('toArray' in Object(iterable)) return iterable.toArray();
  var length = iterable.length || 0, results = new Array(length);
  while (length--) results[length] = iterable[length];
  return results;
}

It doesn't use Array.prototype.slice probably because it isn't available on every browser. I'm afraid the performance is pretty bad as there a the fall back is a javascript loop over the iterable.

In powershell 5.1 you can actually use install-package, but it can't take extra msi arguments.

install-package .\file.msi

Otherwise with start-process and waiting:

start -wait file.msi ALLUSERS=1,INSTALLDIR=C:\FILE

Just add another join:

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

You don't have any error in either of your queries. My guess is the following:

• No records exists between 2013-10-17' and '2013-10-18'
• the records the second query returns you exist after '2013-10-18'

You can delete files and folders recursively like this:

void deleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory())
        for (File child : fileOrDirectory.listFiles())
            deleteRecursive(child);

    fileOrDirectory.delete();
}

Local package is a annoying problem in go.

For some projects in our company we decide not use sub packages at all.

• $ glide install
• $ go get
• $ go install

All work.

For some projects we use sub packages, and import local packages with full path:

import "xxxx.gitlab.xx/xxgroup/xxproject/xxsubpackage

But if we fork this project, then the subpackages still refer the original one.

import array
integerValue = array.array("I", 'y\xcc\xa6\xbb')[0]

Warning: the above is strongly platform-specific. Both the "I" specifier and the endianness of the string->int conversion are dependent on your particular Python implementation. But if you want to convert many integers/strings at once, then the array module does it quickly.

Start by turning the text into a list of lists. That will take care of the parsing part:

lol = list(csv.reader(open('text.txt', 'rb'), delimiter='\t'))

The rest can be done with indexed lookups:

d = dict()
key = lol[6][0]      # cell A7
value = lol[6][3]    # cell D7
d[key] = value       # add the entry to the dictionary
 ...

Intel now provides a Python distribution for Linux / Windows / OS X for free called "Intel distribution for Python".

Its a complete Python distribution (e.g. python.exe is included in the package) which includes some pre-installed modules compiled against Intel's MKL (Math Kernel Library) and thus optimized for faster performance.

The distribution includes the modules NumPy, SciPy, scikit-learn, pandas, matplotlib, Numba, tbb, pyDAAL, Jupyter, and others. The drawback is a bit of lateness in upgrading to more recent versions of Python. For example as of today (1 May 2017) the distribution provides CPython 3.5 while the 3.6 version is already out. But if you don't need the new features they should be perfectly fine.

None of these answers were correct in my case.. the order seems dependent on the alphabetical ordering of the <id> tag, which is an arbitrary string. Hence this forced repo search order:

            <repository>
                <id>1_maven.apache.org</id>
                <releases>  <enabled>true</enabled>  </releases>
                <snapshots> <enabled>true</enabled> </snapshots>
                <url>https://repo.maven.apache.org/maven2</url>
                <layout>default</layout>
            </repository>

            <repository>
                <id>2_maven.oracle.com</id>
                <releases>  <enabled>true</enabled>  </releases>
                <snapshots> <enabled>false</enabled> </snapshots>
                <url>https://maven.oracle.com</url>
                <layout>default</layout>
            </repository>

If I were you I would not use either of them.

The disadvantage of the first one is that the parameter names might collide if there are same values in the list.

The disadvantage of the second one is that you are creating command and parameters for each entity.

The best way is to have the command text and parameters constructed once (use Parameters.Add to add the parameters) change their values in the loop and execute the command. That way the statement will be prepared only once. You should also open the connection before you start the loop and close it after it.

In java, we can do as follows :

AWSLambdaAsync awsLambdaAsync = AWSLambdaAsyncClientBuilder.standard().withRegion("us-east-1").build();

InvokeRequest invokeRequest = new InvokeRequest();
invokeRequest.withFunctionName("youLambdaFunctionNameToCall").withPayload(payload);

InvokeResult invokeResult = awsLambdaAsync.invoke(invokeRequest); 

Here, payload is your stringified java object which needs to be passed as Json object to another lambda in case you need to pass some information from calling lambda to called lambda.

$("your id or class name").css({ 'margin-top': '18px' });  

I came across this thread while trying to clear the date already set. Attempting:

$('#datepicker').val('').datepicker('update');

produced:

TypeError: t.dpDiv is undefined 
https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js -- Line 8

Thinking that perhaps one needed to include the original Datepicker for bootstrap removes the error, but then causes the original Datepicker widget to appear! - so that's obviously wrong and not needed.

Looking further, the crash in jqueryui is in:

    /* Generate the date picker content. */
_updateDatepicker: function(inst) {
    this.maxRows = 4; //Reset the max number of rows being displayed (see #7043)
    datepicker_instActive = inst; // for delegate hover events
    inst.dpDiv.empty().append(this._generateHTML(inst));
    this._attachHandlers(inst);

and inst.pdDiv does not exist.

Investigating further - I realized that what was needed was:

        $formControl = $duedate.find("input");
        $formControl.val('');
        $formControl.removeData();

Which solved my problem. Note I also needed the $formControl.removeData() otherwise the state of the widget would not be reinitialized to the initial state.

I hope this helps someone else. :-)

You can find blocking sql and wait sql by running this:

SELECT
    t1.resource_type ,
    DB_NAME( resource_database_id) AS dat_name ,
    t1.resource_associated_entity_id,
    t1.request_mode,
    t1.request_session_id,
    t2.wait_duration_ms,
    ( SELECT TEXT FROM sys.dm_exec_requests r CROSS apply sys.dm_exec_sql_text ( r.sql_handle ) WHERE r.session_id = t1.request_session_id ) AS wait_sql,
    t2.blocking_session_id,
    ( SELECT TEXT FROM sys.sysprocesses p CROSS apply sys.dm_exec_sql_text ( p.sql_handle ) WHERE p.spid = t2.blocking_session_id ) AS blocking_sql 
FROM
    sys.dm_tran_locks t1,
    sys.dm_os_waiting_tasks t2 
WHERE
    t1.lock_owner_address = t2.resource_address

$dateValue = '2012-01-05';
$year = date('Y',strtotime($dateValue));
$month = date('F',strtotime($dateValue));

The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.

Alternatively, I would suggest turning interactive on in the beginning and at the very last plot, turn it off. All will show up, but they will not disappear as your program will stay around until you close the figures.

import matplotlib.pyplot as plt
from matplotlib import interactive

plt.figure(1)
... code to make figure (1)

interactive(True)
plt.show()

plt.figure(2)
... code to make figure (2)

plt.show()

plt.figure(3)
... code to make figure (3)

interactive(False)
plt.show()

In case of ActionLink, it generally uses HttpUtility.Encode on the link text. In that case you can use HttpUtility.HtmlDecode(myString) it worked for me when using HtmlActionLink to decode the string that I wanted to pass. eg:

  @Html.ActionLink(HttpUtility.HtmlDecode("myString","ActionName",..)

yourArray.indexOf(yourArrayKeyName) > -1

fruit = ['apple', 'grapes', 'banana']

fruit.indexOf('apple') > -1

true

fruit = ['apple', 'grapes', 'banana']

fruit.indexOf('apple1') > -1

false

SELECT 'ALTER TABLE '||substr(c.table_name,1,35)|| 
' DISABLE CONSTRAINT '||constraint_name||' ;' 
FROM user_constraints c, user_tables u 
WHERE c.table_name = u.table_name; 

This statement returns the commands which turn off all the constraints including primary key, foreign keys, and another constraints.

If use generic repository

> lstModule = _ModuleRepository.GetAll().OrderBy(x => new { x.Level,
> x.Rank}).ToList();

else

@GáborNagy's comment on another post was the simplest solution I could find and worked like a charm for me, since he brought a jsfiddle I'm copying it here with a small addition:

CSS:

#wrapper {
    display: table;
    height: 150px;
    width: 800px;
    border: 1px solid red;
}

#cell {
    display: table-cell;
    vertical-align: middle;
}

HTML:

<div id="wrapper">
    <div id="cell">
        <div class="content">
            Content goes here
        </div>
    </div>
</div>

If you wish to also align it horizontally you'd have to add another div "inner-cell" inside the "cell" div, and give it this style:

#inner-cell{
      width: 250px;
      display: block;
      margin: 0 auto;
}

Running Latest Code Igniter 3.10

$this->load->helper('uri'); // or you can autoload it in config

print base_url($this->uri->uri_string());

This works for me:

sudo apt-get install php5.6-curl

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

Try itext. Add dependency to your build.gradle for latest as of this post

Note: special version for android, trailing "g":

You should put it into command line in windows.

mysqladmin -u [username] -p flush-hosts
**** [MySQL password]

or

mysqladmin flush-hosts -u [username] -p
**** [MySQL password]

For network login use the following command:

mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts 

you can permanently solution your problem by editing my.ini file[Mysql configuration file] change variables max_connections = 10000;

or

login into MySQL using command line -

mysql -u [username] -p
**** [MySQL password]

put the below command into MySQL window

SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;

check veritable using command-

show variables like "max_connections";
show variables like "max_connect_errors";

Now the <b> element is deprecated. <strong> renders as <b>, and <em> renders as <i>.

tv.setText(Html.fromHtml("<strong>bold</strong> and <em>italic</em> "));

this works fine for me

As posted by 'Dan' in a similar thread, there is a possible fix if you're not using a sprite:

How do I make background-size work in IE?

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale');

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale')";

However, this scales the entire image to fit in the allocated area. So if your using a sprite, this may cause issues.

Caution
The filter has a flaw, any links inside the allocated area are no longer clickable.

Inside class Testclass:

public function __construct($new_value)
{
    $this->testvar = $new_value;
}

Not only is it the preferred way, it's the only reasonable way. Because strings are immutable, in order to "remove" a char from a string you have to create a new string whenever you want a different string value.

You may be wondering why strings are immutable, given that you have to make a whole new string every time you change a character. After all, C strings are just arrays of characters and are thus mutable, and some languages that support strings more cleanly than C allow mutable strings as well. There are two reasons to have immutable strings: security/safety and performance.

Security is probably the most important reason for strings to be immutable. When strings are immutable, you can't pass a string into some library and then have that string change from under your feet when you don't expect it. You may wonder which library would change string parameters, but if you're shipping code to clients you can't control their versions of the standard library, and malicious clients may change out their standard libraries in order to break your program and find out more about its internals. Immutable objects are also easier to reason about, which is really important when you try to prove that your system is secure against particular threats. This ease of reasoning is especially important for thread safety, since immutable objects are automatically thread-safe.

Performance is surprisingly often better for immutable strings. Whenever you take a slice of a string, the Python runtime only places a view over the original string, so there is no new string allocation. Since strings are immutable, you get copy semantics without actually copying, which is a real performance win.

Eric Lippert explains more about the rationale behind immutable of strings (in C#, not Python) here.

You're mixing notations. It should be:

<img src="folder/file.jpg" width="200" height="200">

(note, no px). Or:

<img src="folder/file.jpg" style="width: 200px; height: 200px;">

(using the style attribute) The style attribute could be replaced with the following CSS:

#mydiv img {
    width: 200px;
    height: 200px;
}

or

#mydiv img {
    width: 100%;
    height: 100%;
}

If you use any full screen window (having its WindowState = WindowState.Maximized, WindowStyle = WindowStyle.None), you can wrap its contents in System.Windows.Controls.Canvas like this:

<Canvas Name="MyCanvas" Width="auto" Height="auto">
...
</Canvas>

Then you can use MyCanvas.ActualWidth and MyCanvas.ActualHeight to get the resolution of the current screen, with DPI settings taken into account and in device independent units. It doesn't add any margins as the maximized window itself does.

(Canvas accepts UIElements as children, so you should be able to use it with any content.)

IE 8 actually uses the first button it encounters submit or button. Instead of easily indicating which is desired by making it a input type=submit the order on the page is actually significant.

Because I hate repeating complex logic, here's a generic version of Slauma's solution.

Here's my update method. Note that in a detached scenario, sometimes your code will read data and then update it, so it's not always detached.

public async Task UpdateAsync(TempOrder order)
{
    order.CheckNotNull(nameof(order));
    order.OrderId.CheckNotNull(nameof(order.OrderId));

    order.DateModified = _dateService.UtcNow;

    if (_context.Entry(order).State == EntityState.Modified)
    {
        await _context.SaveChangesAsync().ConfigureAwait(false);
    }
    else // Detached.
    {
        var existing = await SelectAsync(order.OrderId!.Value).ConfigureAwait(false);
        if (existing != null)
        {
            order.DateModified = _dateService.UtcNow;
            _context.TrackChildChanges(order.Products, existing.Products, (a, b) => a.OrderProductId == b.OrderProductId);
            await _context.SaveChangesAsync(order, existing).ConfigureAwait(false);
        }
    }
}

CheckNotNull is defined here.

I don't know whether its the newer version of php, but this works. I'm using php 5.6

    <?php
    class Person
    {
       public $name;

       public function save()
       {
          print_r($this);
       }
    }

   $p = new Person;
   $p->name = "Ganga";
   $p->age = 23;

   $p->save();

This is the result. The save method actually gets the new property

    Person Object
    (
       [name] => Ganga
       [age] => 23
    )

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

application because .js-Files aren't something a user wants to read but something that should get executed.

The NumberFormat class will only parse the string until it reaches a non-parseable character:

((Number)NumberFormat.getInstance().parse("123e")).intValue()

will hence return 123.

Here is an efficient way to solve this question using For loops in Java

 public static void main(String[] args) {

    int [] numbers = { 1, 2, 3, 4 };
    int size = numbers.length;

    int sum = 0;
    for (int i = 0; i < size; i++) {
        sum += numbers[i];
    }

    System.out.println(sum);
}

You could try giving an ID to the form, in order to get ahold of it, and then call form.submit() from a Javascript call.

As others have pointed out, ideally, the foreign key would be created as a reference to a primary key (usually an IDENTITY column). However, we don't live in an ideal world, and sometimes even a "small" change to a schema can have significant ripple effects to the application logic.

Consider the case of a Customer table with a SSN column (and a dumb primary key), and a Claim table that also contains a SSN column (populated by business logic from the Customer data, but no FK exists). The design is flawed, but has been in use for several years, and three different applications have been built on the schema. It should be obvious that ripping out Claim.SSN and putting in a real PK-FK relationship would be ideal, but would also be a significant overhaul. On the other hand, putting a UNIQUE constraint on Customer.SSN, and adding a FK on Claim.SSN, could provide referential integrity, with little or no impact on the applications.

Don't get me wrong, I'm all for normalization, but sometimes pragmatism wins over idealism. If a mediocre design can be helped with a band-aid, surgery might be avoided.

To account for leading and trailing whitespace, you probably want to use normalize-space()

//div[contains(@class, 'Caption') and normalize-space(.)='Model saved']

and

//div[@id='alertLabel' and normalize-space(.)='Save to server successful']

Note that //div[contains(@class, 'Caption') and normalize-space(.//text())='Model saved'] also works.

Here's the lowdown on Mac IDE's for PHP

NetBeans Free! Plus, the best functionality of all offerings. Includes inline database connections, code completion, syntax checking, color coding, split views etc. Downside: It's a memory hog on the Mac. Be prepared to allow half a gig of memory then you'll need to shut down and restart.

Komodo A step above a Text Editor. Does not support database connections or split views. Color coding and syntax checking are there to an extent. The project control on Komodo is very unwieldy and strange compared to the other IDEs.

Aptana The perfect solution. Eclipsed based and uses the Aptana PHP plug in. Real time syntax checking, word wrap, drag and drop split views, database connections and a slew of other excellent features. Downside: Not a supported product any more. Aptana Studio 2.0+ uses PDT which is a watered down, under-developed (at present) php plug in.

Zend Studio - Almost identical to Aptana, except no word wrap and you can't change alot of the php configuration on the MAC apparently due to bugs.

Coda Created by Panic, Coda has nice integration with source control and their popular FTP client, transmit. They also have a collaboration feature which is cool for pair-programming.

PhpEd with Parallels or Wine. The best IDE for Windows has all the feature you could need and is worth the effort to pass it through either Parallels or Wine.

Dreamweaver Good for Javascript/HTML/CSS, but only marginal for PHP. There is some color coding, but no syntax checking or code completion native to the package. Database connections are supported, and so are split views.

I'm using NetBeans, which is free, and feature rich. I can deal with the memory issues for a while, but it could be slow coming to the MAC.

Looks like this is new as of Python 3.4 - pathlib.

from pathlib import Path

Path('path/to/file.txt').touch()

This will create a file.txt at the path.

--

Path.touch(mode=0o777, exist_ok=True)

Create a file at this given path. If mode is given, it is combined with the process’ umask value to determine the file mode and access flags. If the file already exists, the function succeeds if exist_ok is true (and its modification time is updated to the current time), otherwise FileExistsError is raised.

You can try this (worked in my case)

If you want to test if the first char of a string is an int:

if (parseInt(YOUR_STRING.slice(0, 1))) {
    alert("first char is int")
} else {
    alert("first char is not int")
}

If you want to test if the char is a int:

if (parseInt(YOUR_CHAR)) {
    alert("first char is int")
} else {
    alert("first char is not int")
}

Sometimes you can reference a Windows "shortcut" file to launch an application instead of using a ".bat" file, and it won't have the residual prompt problem. But it's not as flexible as bat files.

As you have figured out that you cannot do it the way you have done in Java (or C#). Here is another suggestion, you could pass in the reference of the object as an argument and return bool value. If the result is found in your collection, you could assign it to the reference being passed and return ‘true’, otherwise return ‘false’. Please consider this code.

typedef std::map<string, Operator> OPERATORS_MAP;

bool OperatorList::tryGetOperator(string token, Operator& op)
{
    bool val = false;

    OPERATORS_MAP::iterator it = m_operators.find(token);
    if (it != m_operators.end())
    {
        op = it->second;
        val = true;
    }
    return val;
}

The function above has to find the Operator against the key 'token', if it finds the one it returns true and assign the value to parameter Operator& op.

The caller code for this routine looks like this

Operator opr;
if (OperatorList::tryGetOperator(strOperator, opr))
{
    //Do something here if true is returned.
}

Change this line:

mMyListView.setAdapter(new ArrayAdapter<String>(this, 
                           android.R.layout.simple_list_item_1, 
                           listItems));

to:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                   android.R.layout.simple_list_item_1, 
                                   listItems)
mMyListView.setAdapter(adapter);

and after updating the value of a list item, call:

adapter.notifyDataSetChanged();

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

The redirect function cleans the output buffer and does a header('Location:...'); redirection and exits script execution. The part you are trying to echo will never be outputted.

You should either notify on the download page or notify on the page you redirect to about the missing data.

    --DROP TABLE #Employee
    CREATE TABLE #Employee(EmpId BIGINT IDENTITY,EmpName VARCHAR(25),Designation VARCHAR(25),ManagerID BIGINT)

    INSERT INTO #Employee VALUES('M11M','Manager',NULL)
    INSERT INTO #Employee VALUES('P11P','Manager',NULL)

    INSERT INTO #Employee VALUES('AA','Clerk',1)
    INSERT INTO #Employee VALUES('AB','Assistant',1)
    INSERT INTO #Employee VALUES('ZC','Supervisor',2)
    INSERT INTO #Employee VALUES('ZD','Security',2)


    SELECT * FROM #Employee (NOLOCK)

    ;
    WITH Emp_CTE 
    AS
    (
        SELECT EmpId,EmpName,Designation, ManagerID
              ,CASE WHEN ManagerID IS NULL THEN EmpId ELSE ManagerID END ManagerID_N
        FROM #Employee  
    )
    select EmpId,EmpName,Designation, ManagerID
    FROM Emp_CTE
    order BY ManagerID_N, EmpId

If you changed the ruby version you're using with rvm use, remove Gemfile.lock and try again.

Five years later with introduction of React Hooks there is now much more elegant way of doing it with use useContext hook.

You define context in a global scope, export variables, objects and functions in the parent component and then wrap children in the App in a context provided and import whatever you need in child components. Below is a proof of concept.

import React, { useState, useContext } from "react";
import ReactDOM from "react-dom";
import styles from "./styles.css";

// Create context container in a global scope so it can be visible by every component
const ContextContainer = React.createContext(null);

const initialAppState = {
  selected: "Nothing"
};

function App() {
  // The app has a state variable and update handler
  const [appState, updateAppState] = useState(initialAppState);

  return (
    <div>
      <h1>Passing state between components</h1>

      {/* 
          This is a context provider. We wrap in it any children that might want to access
          App's variables.
          In 'value' you can pass as many objects, functions as you want. 
           We wanna share appState and its handler with child components,           
       */}
      <ContextContainer.Provider value={{ appState, updateAppState }}>
        {/* Here we load some child components */}
        <Book title="GoT" price="10" />
        <DebugNotice />
      </ContextContainer.Provider>
    </div>
  );
}

// Child component Book
function Book(props) {
  // Inside the child component you can import whatever the context provider allows.
  // Earlier we passed value={{ appState, updateAppState }}
  // In this child we need the appState and the update handler
  const { appState, updateAppState } = useContext(ContextContainer);

  function handleCommentChange(e) {
    //Here on button click we call updateAppState as we would normally do in the App
    // It adds/updates comment property with input value to the appState
    updateAppState({ ...appState, comment: e.target.value });
  }

  return (
    <div className="book">
      <h2>{props.title}</h2>
      <p>${props.price}</p>
      <input
        type="text"
        //Controlled Component. Value is reverse vound the value of the variable in state
        value={appState.comment}
        onChange={handleCommentChange}
      />
      <br />
      <button
        type="button"
        // Here on button click we call updateAppState as we would normally do in the app
        onClick={() => updateAppState({ ...appState, selected: props.title })}
      >
        Select This Book
      </button>
    </div>
  );
}

// Just another child component
function DebugNotice() {
  // Inside the child component you can import whatever the context provider allows.
  // Earlier we passed value={{ appState, updateAppState }}
  // but in this child we only need the appState to display its value
  const { appState } = useContext(ContextContainer);

  /* Here we pretty print the current state of the appState  */
  return (
    <div className="state">
      <h2>appState</h2>
      <pre>{JSON.stringify(appState, null, 2)}</pre>
    </div>
  );
}

const rootElement = document.body;
ReactDOM.render(<App />, rootElement);

You can run this example in the Code Sandbox editor.

No need to install nodemon globally. Just run this npx nodemon <scriptname.js>. That's it.

Remove yarn.lock , package-lock.json, node_modules

and then

npm install -f 

Worked for me

I don't know what you mean by 'manually'. You can choose a colourmap and make a colour array easily enough:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm

x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]

colors = cm.rainbow(np.linspace(0, 1, len(ys)))
for y, c in zip(ys, colors):
    plt.scatter(x, y, color=c)

Or you can make your own colour cycler using itertools.cycle and specifying the colours you want to loop over, using next to get the one you want. For example, with 3 colours:

import itertools

colors = itertools.cycle(["r", "b", "g"])
for y in ys:
    plt.scatter(x, y, color=next(colors))

Come to think of it, maybe it's cleaner not to use zip with the first one neither:

colors = iter(cm.rainbow(np.linspace(0, 1, len(ys))))
for y in ys:
    plt.scatter(x, y, color=next(colors))

You can (should) use CROSS JOIN. Following query will be equivalent to yours:

SELECT 
   table1.columnA
 , table2.columnA
FROM table1 
CROSS JOIN table2
WHERE table1.columnA = 'Some value'

or you can even use INNER JOIN with some always true conditon:

FROM table1 
INNER JOIN table2 ON 1=1

I know the answer by @Pascal Thivent has solved the issue. I would like to add a bit more to his answer to others who might be surfing this thread.

If you are like me in the initial days of learning and wrapping your head around the concept of using the @OneToMany annotation with the 'mappedBy' property, it also means that the other side holding the @ManyToOne annotation with the @JoinColumn is the 'owner' of this bi-directional relationship.

Also, mappedBy takes in the instance name (mCustomer in this example) of the Class variable as an input and not the Class-Type (ex:Customer) or the entity name(Ex:customer).

BONUS : Also, look into the orphanRemoval property of @OneToMany annotation. If it is set to true, then if a parent is deleted in a bi-directional relationship, Hibernate automatically deletes it's children.

In case anybody wonders how how to get rid of the rest of the white margin after applying plt.tight_layout() or fig.tight_layout(): With the parameter pad (which is 1.08 by default), you're able to make it even tighter: "Padding between the figure edge and the edges of subplots, as a fraction of the font size." So for example

plt.tight_layout(pad=0.05)

will reduce it to a very small margin. Putting 0 doesn't work for me, as it makes the box of the subplot be cut off a little, too.

The element you were trying to find wasn’t in the DOM when your script ran.

The position of your DOM-reliant script can have a profound effect upon its behavior. Browsers parse HTML documents from top to bottom. Elements are added to the DOM and scripts are (generally) executed as they're encountered. This means that order matters. Typically, scripts can't find elements which appear later in the markup because those elements have yet to be added to the DOM.

Consider the following markup; script #1 fails to find the <div> while script #2 succeeds:

<script>_x000D_
  console.log("script #1: %o", document.getElementById("test")); // null_x000D_
</script>_x000D_
<div id="test">test div</div>_x000D_
<script>_x000D_
  console.log("script #2: %o", document.getElementById("test")); // <div id="test" ..._x000D_
</script>

So, what should you do? You've got a few options:

Option 1: Move your script

Move your script further down the page, just before the closing body tag. Organized in this fashion, the rest of the document is parsed before your script is executed:

<body>_x000D_
  <button id="test">click me</button>_x000D_
  <script>_x000D_
    document.getElementById("test").addEventListener("click", function() {_x000D_
      console.log("clicked: %o", this);_x000D_
    });_x000D_
  </script>_x000D_
</body><!-- closing body tag -->

_{Note: Placing scripts at the bottom is generally considered a best practice.}

Option 2: jQuery's ready()

Defer your script until the DOM has been completely parsed, using $(handler):

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script>_x000D_
  $(function() {_x000D_
    $("#test").click(function() {_x000D_
      console.log("clicked: %o", this);_x000D_
    });_x000D_
  });_x000D_
</script>_x000D_
<button id="test">click me</button>

_{Note: You could simply bind to DOMContentLoaded or window.onload but each has its caveats. jQuery's ready() delivers a hybrid solution.}

Option 3: Event Delegation

Delegated events have the advantage that they can process events from descendant elements that are added to the document at a later time.

When an element raises an event (provided that it's a bubbling event and nothing stops its propagation), each parent in that element's ancestry receives the event as well. That allows us to attach a handler to an existing element and sample events as they bubble up from its descendants... even those added after the handler is attached. All we have to do is check the event to see whether it was raised by the desired element and, if so, run our code.

jQuery's on() performs that logic for us. We simply provide an event name, a selector for the desired descendant, and an event handler:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script>_x000D_
  $(document).on("click", "#test", function(e) {_x000D_
    console.log("clicked: %o",  this);_x000D_
  });_x000D_
</script>_x000D_
<button id="test">click me</button>

_{Note: Typically, this pattern is reserved for elements which didn't exist at load-time or to avoid attaching a large amount of handlers. It's also worth pointing out that while I've attached a handler to document (for demonstrative purposes), you should select the nearest reliable ancestor.}

Option 4: The defer attribute

Use the defer attribute of <script>.

[defer, a Boolean attribute,] is set to indicate to a browser that the script is meant to be executed after the document has been parsed, but before firing DOMContentLoaded.

<script src="https://gh-canon.github.io/misc-demos/log-test-click.js" defer></script>_x000D_
<button id="test">click me</button>

For reference, here's the code from that external script:

document.getElementById("test").addEventListener("click", function(e){
   console.log("clicked: %o", this); 
});

<sub>Note: The defer attribute certainly seems like a magic bullet but it's important to be aware of the caveats...
1. defer can only be used for external scripts, i.e.: those having a src attribute.
2. be aware of browser support, i.e.: buggy implementation in IE < 10</sub>

function deepclone(obj) {
    let newObj = {};

    if (typeof obj === 'object') {
        for (let key in obj) {
            let property = obj[key],
                type = typeof property;
            switch (type) {
                case 'object':
                    if( Object.prototype.toString.call( property ) === '[object Array]' ) {
                        newObj[key] = [];
                        for (let item of property) {
                            newObj[key].push(this.deepclone(item))
                        }
                    } else {
                        newObj[key] = deepclone(property);
                    }
                    break;
                default:
                    newObj[key] = property;
                    break;

            }
        }
        return newObj
    } else {
        return obj;

It used to help to switch to trusty32, but the situation now got worse again: I tried to use Homestead 2.0 and now I've got the Connection Timeout problem again, which would't usually be a problem, because switching to 32bit helped before. But now I can't just add a line like config.vm.box="ubuntu/trusty32" because we don't have a classic Homestead.yaml file anymore, the values in the new 2.0 Homestead.yaml file just seem to be inserted into the real one in the background and there ist no Vagrantfile available that I could manually edit ...

Hope someone can help ...

Make the value a list, e.g.

a["abc"] = [1, 2, "bob"]

UPDATE:

There are a couple of ways to add values to key, and to create a list if one isn't already there. I'll show one such method in little steps.

key = "somekey"
a.setdefault(key, [])
a[key].append(1)

Results:

>>> a
{'somekey': [1]}

Next, try:

key = "somekey"
a.setdefault(key, [])
a[key].append(2)

Results:

>>> a
{'somekey': [1, 2]}

The magic of setdefault is that it initializes the value for that key if that key is not defined, otherwise it does nothing. Now, noting that setdefault returns the key you can combine these into a single line:

a.setdefault("somekey",[]).append("bob")

Results:

>>> a
{'somekey': [1, 2, 'bob']}

You should look at the dict methods, in particular the get() method, and do some experiments to get comfortable with this.

As of Oct 2019, SQL Server Management Studio, they did not upgraded the SSMS to add create ER Diagram feature.

I would suggest try using DBWeaver from here :

https://dbeaver.io/download/

I am using Mac and Windows both and I was able to download the community edition and logged into my SQL server database and was able to create the ER diagram using the DB Weaver.

It seems to work when I replace the

Runtime.getRuntime().exec("rmiregistry 2020");

by

LocateRegistry.createRegistry(2020);

anyone an idea why? What's the difference?

This can happen (at least once for me ;) after installing the new version of IntelliJ and the IntelliJ plugins have not yet updated.

You may have to manually do the Check for updates… from IntelliJ Help menu.

I would rather use plt.clf() after every plt.show() to just clear the current figure instead of closing and reopening it, keeping the window size and giving you a better performance and much better memory usage.

Similarly, you could do plt.cla() to just clear the current axes.

To clear a specific axes, useful when you have multiple axes within one figure, you could do for example:

fig, axes = plt.subplots(nrows=2, ncols=2)

axes[0, 1].clear()

Clojure solution:

(defn pick-random [set] (let [sq (seq set)] (nth sq (rand-int (count sq)))))

DateTime inherits its equals method from AbstractInstant. It is implemented as such

public boolean equals(Object readableInstant) {     // must be to fulfil ReadableInstant contract     if (this == readableInstant) {         return true;     }     if (readableInstant instanceof ReadableInstant == false) {         return false;     }     ReadableInstant otherInstant = (ReadableInstant) readableInstant;     return         getMillis() == otherInstant.getMillis() &&         FieldUtils.equals(getChronology(), otherInstant.getChronology()); } 

Notice the last line comparing chronology. It's possible your instances' chronologies are different.

For converting categorical data in column C of dataset data, we need to do the following:

from sklearn.preprocessing import LabelEncoder 
labelencoder= LabelEncoder() #initializing an object of class LabelEncoder
data['C'] = labelencoder.fit_transform(data['C']) #fitting and transforming the desired categorical column.

This project https://github.com/FilipDeVos/sp_select has a stored procedure sp_select which allows for selecting from a temp table.

Usage:

exec sp_select 'tempDb..#myTempTable'

While debugging a stored procedure you can open a new tab and run this command to see the contents of the temp table.

I just solve this error while using capybara in ror project by adding:

Capybara.ignore_elements = true

to features/support/env.rb.

Should Use this way to convert into map :

    String student[] = students.split("\\{|}");
    String id_name[] = student[1].split(",");

    Map<String,String> studentIdName = new HashMap<>();

    for (String std: id_name) {
        String str[] = std.split("=");
        studentIdName.put(str[0],str[1]);
  }

I added the start and exit which works. Without both it was not working

start C:/Anaconda3/Library/bin/pyrcc4.exe -py3 {path}/Resourses.qrc -{path}/Resourses_rc.py
exit

Use dt.days to obtain the days attribute as integers.

For eg:

In [14]: s = pd.Series(pd.timedelta_range(start='1 days', end='12 days', freq='3000T'))

In [15]: s
Out[15]: 
0    1 days 00:00:00
1    3 days 02:00:00
2    5 days 04:00:00
3    7 days 06:00:00
4    9 days 08:00:00
5   11 days 10:00:00
dtype: timedelta64[ns]

In [16]: s.dt.days
Out[16]: 
0     1
1     3
2     5
3     7
4     9
5    11
dtype: int64

More generally - You can use the .components property to access a reduced form of timedelta.

In [17]: s.dt.components
Out[17]: 
   days  hours  minutes  seconds  milliseconds  microseconds  nanoseconds
0     1      0        0        0             0             0            0
1     3      2        0        0             0             0            0
2     5      4        0        0             0             0            0
3     7      6        0        0             0             0            0
4     9      8        0        0             0             0            0
5    11     10        0        0             0             0            0

Now, to get the hours attribute:

In [23]: s.dt.components.hours
Out[23]: 
0     0
1     2
2     4
3     6
4     8
5    10
Name: hours, dtype: int64

Thanks Sanoj, that worked for me.
However iOS does not support "onbeforeunload" on iPhone. Workaround for me was to set localStorage with js:

<button onclick="myFunction()">Click me</button>

<script>
document.addEventListener("DOMContentLoaded", function(event) { 
            var scrollpos = localStorage.getItem('scrollpos');
            if (scrollpos) window.scrollTo(0, scrollpos);
        });
function myFunction() {
  localStorage.setItem('scrollpos', window.scrollY);
  location.reload(); 
}
</script>

I just found the simplest way to find the channel ID of any YouTube channel !!

Step 1: Play a video of that channel.

Step 2: Click the channel name under that video.

Step 3: Look at the browser address bar.
