How to auto increment by one, starting at 10 in MySQL:

create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;

'10', 'abc'
'11', 'def'
'12', 'xyz'

This auto increments the id column by one starting at 10.

Auto increment in MySQL by 5, starting at 10:

drop table foobar
create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
SET @@auto_increment_increment=5;
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;
'11', 'abc'
'16', 'def'
'21', 'xyz'

This auto increments the id column by 5 each time, starting at 10.

I run the service at IPLocate.io, which you can hook into for free with one easy call:

<?php
$res = file_get_contents('https://www.iplocate.io/api/lookup/8.8.8.8');
$res = json_decode($res);

echo $res->country; // United States
echo $res->continent; // North America
echo $res->latitude; // 37.751
echo $res->longitude; // -97.822

var_dump($res);

The $res object will contain your geolocation fields like country, city, etc.

Bash

To get list of keys in Bash, follow the these steps.

First, define the following wrapper function to make it simple to use (copy and paste into shell):

function memcmd() {
  exec {memcache}<>/dev/tcp/localhost/11211
  printf "%s\n%s\n" "$*" quit >&${memcache}
  cat <&${memcache}
}

Memcached 1.4.31 and above

You can use lru_crawler metadump all command to dump (most of) the metadata for (all of) the items in the cache.

As opposed to cachedump, it does not cause severe performance problems and has no limits on the amount of keys that can be dumped.

Example command by using the previously defined function:

memcmd lru_crawler metadump all

See: ReleaseNotes1431.

Memcached 1.4.30 and below

Get list of slabs by using items statistics command, e.g.:

memcmd stats items

For each slub class, you can get list of items by specifying slub id along with limit number (0 - unlimited):

memcmd stats cachedump 1 0
memcmd stats cachedump 2 0
memcmd stats cachedump 3 0
memcmd stats cachedump 4 0
...

^{Note: You need to do this for each memcached server.}

To list all the keys from all stubs, here is the one-liner (per one server):

for id in $(memcmd stats items | grep -o ":[0-9]\+:" | tr -d : | sort -nu); do
    memcmd stats cachedump $id 0
done

^{Note: The above command could cause severe performance problems while accessing the items, so it's not advised to run on live.}

Notes:

stats cachedump only dumps the HOT_LRU (IIRC?), which is managed by a background thread as activity happens. This means under a new enough version which the 2Q algo enabled, you'll get snapshot views of what's in just one of the LRU's.

If you want to view everything, lru_crawler metadump 1 (or lru_crawler metadump all) is the new mostly-officially-supported method that will asynchronously dump as many keys as you want. you'll get them out of order but it hits all LRU's, and unless you're deleting/replacing items multiple runs should yield the same results.

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

This can be accomplished without javascript, with this metatag:

<meta http-equiv="refresh" content="5" >

where content ="5" are the seconds that the page will wait until refreshed.

But you said only if there was no activity, what kind for activity would that be?

This error basically happens when the specific port is not free. So there are two solutions, you can free that port by killing or closing the service which is using it or you can run your application (tomcat) on a different port.

Solution 1: Free the port

On a Linux machine you can find the process-id of port's consumer and then kill it. Use the following command (it is assume that the default port is 8080)

netstat -pnltu | grep -i "8080"

The output of the above-mentioned command would be something like:

tcp6   0  0 :::8080    :::*      LISTEN      20674/java 

Then you can easily kill the process with its processid:

kill 20674

On a windows machine to find a processid use netstat -ano -p tcp |find "8080". To kill the process use taskkill /F /PID 1234 (instead of 1234 enter the founded processid).

Solution 2: Change the default port

In the development process developers use the port 8080 that you can change it easily. You need to specify your desired port number in the application.properties file of your project (/src/main/resources/application.properties) by using the following specification:

server.port=8081

You can also set an alternative port number while executing the .jar file

- java -jar spring-boot-application.jar --server.port=8081

Please notice that sometimes (not necessarily) you have to change other ports too like:

management.port=
tomcat.jvmroute=
tomcat.ajp.port=
tomcat.ajp.redirectPort=
etc...

You may also need to enable the World Wide Web Service inbound firewall rule.

On Windows 7: Start -> Control Panel -> Windows Firewall -> Advanced Settings -> Inbound Rules

Find World Wide Web Services (HTTP Traffic-In) in the list and select to enable the rule. Change is pretty much immediate.

var jArr = [
{
    id : "001",
    name : "apple",
    category : "fruit",
    color : "red"
},
{
    id : "002",
    name : "melon",
    category : "fruit",
    color : "green"
},
{
    id : "003",
    name : "banana",
    category : "fruit",
    color : "yellow"
}
]

var tableData = '<table><tr><td>Id</td><td>Name</td><td>Category</td><td>Color</td></tr>';
$.each(jArr, function(index, data) {
 tableData += '<tr><td>'+data.id+'</td><td>'+data.name+'</td><td>'+data.category+'</td><td>'+data.color+'</td></tr>';
});

$('div').html(tableData);

A good gotcha is any error code > 255 will be converted to error code % 256. One should be specifically careful about this if they are using a custom error code > 255 and expecting the exact error code in the application logic. http://www.tldp.org/LDP/abs/html/exitcodes.html

MSDN seems to have an article for this now:

Intro:

By default, Windows Communication Foundation (WCF) makes endpoints available only to SOAP clients. In How to: Create a Basic WCF Web HTTP Service, an endpoint is made available to non-SOAP clients. There may be times when you want to make the same contract available both ways, as a Web endpoint and as a SOAP endpoint. This topic shows an example of how to do this.

Is there a prize for being lazy and using the transpose function of NumPy arrays? ;)

import numpy as np

a = np.array([(1,2,3), (4,5,6)])

b = a.transpose()

One approach:

(
  shopt -s nullglob
  files=(/home/edward/bank1/fiche/Test*)
  if [[ "${#files[@]}" -gt 0 ]] ; then
    echo found one
  else
    echo found none
  fi
)

Explanation:

• shopt -s nullglob will cause /home/edward/bank1/fiche/Test* to expand to nothing if no file matches that pattern. (Without it, it will be left intact.)
• ( ... ) sets up a subshell, preventing shopt -s nullglob from "escaping".
• files=(/home/edward/bank1/fiche/Test*) puts the file-list in an array named files. (Note that this is within the subshell only; files will not be accessible after the subshell exits.)
• "${#files[@]}" is the number of elements in this array.

Edited to address subsequent question ("What if i also need to check that these files have data in them and are not zero byte files"):

For this version, we need to use -s (as you did in your question), which also tests for the file's existence, so there's no point using shopt -s nullglob anymore: if no file matches the pattern, then -s on the pattern will be false. So, we can write:

(
  found_nonempty=''
  for file in /home/edward/bank1/fiche/Test* ; do
    if [[ -s "$file" ]] ; then
      found_nonempty=1
    fi
  done
  if [[ "$found_nonempty" ]] ; then
    echo found one
  else
    echo found none
  fi
)

(Here the ( ... ) is to prevent file and found_file from "escaping".)

Don't know, if it's a good idea or not: After trying all other solutions without success, I just renamed /usr/local/lib/dtrace, linked node and re-renamed the directory again. After that, node worked as expected.

For ubuntu me help - sudo dpkg-reconfigure phpmyadmin

For reference (this is the correct answer):

Inside a .d.ts definition file

type MyGlobalFunctionType = (name: string) => void

If you work in the browser, you add members to the browser's window context by reopening Window's interface:

interface Window {
  myGlobalFunction: MyGlobalFunctionType
}

Same idea for NodeJS:

declare module NodeJS {
  interface Global {
    myGlobalFunction: MyGlobalFunctionType
  }
}

Now you declare the root variable (that will actually live on window or global)

declare const myGlobalFunction: MyGlobalFunctionType;

Then in a regular .ts file, but imported as side-effect, you actually implement it:

global/* or window */.myGlobalFunction = function (name: string) {
  console.log("Hey !", name);
};

And finally use it elsewhere in the codebase, with either:

global/* or window */.myGlobalFunction("Kevin");

myGlobalFunction("Kevin");

Use display: none instead. Besides, this is probably what you need, because this also truncates the page by removing the space the table occupies, whereas visibility: hidden leaves the white space left by the table.

The docs give a pretty good explanation of the difference between apply() and commit():

Unlike commit(), which writes its preferences out to persistent storage synchronously, apply() commits its changes to the in-memory SharedPreferences immediately but starts an asynchronous commit to disk and you won't be notified of any failures. If another editor on this SharedPreferences does a regular commit() while a apply() is still outstanding, the commit() will block until all async commits are completed as well as the commit itself. As SharedPreferences instances are singletons within a process, it's safe to replace any instance of commit() with apply() if you were already ignoring the return value.

you can loop through the data frame like this .

for ad in range(1,dataframe_c.size):
    print(dataframe_c.values[ad])

What about /disable, and /enable switch for a /change command?

schtasks.exe /change /s <machine name> /tn <task name> /disable
schtasks.exe /change /s <machine name> /tn <task name> /enable

find . -print0|while read -d $'\0' file; do echo "$file"; done

Array.Equals() appears to only test for the same instance.

There doesn't appear to be a method that compares the values but it would be very easy to write.

Just compare the lengths, if not equal, return false. Otherwise, loop through each value in the array and determine if they match.

Use git checkout instead of git stash apply:

$ git checkout stash -- .
$ git commit

This will restore all the files in the current directory to their stashed version.

If there are changes to other files in the working directory that should be kept, here is a less heavy-handed alternative:

$ git merge --squash --strategy-option=theirs stash

If there are changes in the index, or the merge will touch files with local changes, git will refuse to merge. Individual files can be checked out from the stash using

$ git checkout stash -- <paths...>

or interactively with

$ git checkout -p stash

The encodings are spelled out in the buffer documentation.

Buffers and character encodings:

Character Encodings

• utf8: Multi-byte encoded Unicode characters. Many web pages and other document formats use UTF-8. This is the default character encoding.
• utf16le: Multi-byte encoded Unicode characters. Unlike utf8, each character in the string will be encoded using either 2 or 4 bytes.
• latin1: Latin-1 stands for ISO-8859-1. This character encoding only supports the Unicode characters from U+0000 to U+00FF.

Binary-to-Text Encodings

• base64: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.
• hex: Encode each byte as two hexadecimal characters.

Legacy Character Encodings

• ascii: For 7-bit ASCII data only. Generally, there should be no reason to use this encoding, as 'utf8' (or, if the data is known to always be ASCII-only, 'latin1') will be a better choice when encoding or decoding ASCII-only text.
• binary: Alias for 'latin1'.
• ucs2: Alias of 'utf16le'.

It is now this For swift 3,

    let button = (sender as AnyObject)
    button.setTitle("Your text", for: .normal)

(The constant declaration of the variable is not necessary just make sure you use the sender from the button like this) :

    (sender as AnyObject).setTitle("Your text", for: .normal)

Remember this is used inside the IBAction of your button.

This will give you all property names and values defined in your dynamic variable.

dynamic d = { // your code };
object o = d;
string[] propertyNames = o.GetType().GetProperties().Select(p => p.Name).ToArray();
foreach (var prop in propertyNames)
{
    object propValue = o.GetType().GetProperty(prop).GetValue(o, null);
}

Hive apparently supports INSERT...VALUES starting in Hive 0.14.

You have to make sure the application is uninstalled.

In your phone, try going to settings/applications and show the list of all your installed applications, then make sure the application is uninstalled for all users (in my case I had uninstalled the application but still for others).

When you change files or add a new ones in repository you first must stage them.

git add <file>

or if you want to stage all

git add .

By doing this you are telling to git what files you want in your next commit. Then you do:

git commit -m 'your message here'

You use

git push origin master

where origin is the remote repository branch and master is your local repository branch.

being overwhelmed by being VERY NEW to python i missed some very simple and useful commands given here: Print in terminal with colors using Python? -

eventually decided to use CLINT as an answer that was given there by great and smart people

In Python 3.6+:

import datetime

timestamp = 1579117901
value = datetime.datetime.fromtimestamp(timestamp)
print(f"{value:%Y-%m-%d %H:%M:%S}")

Output (in UTC)

2020-01-15 19:51:41

Explanation

• Line #1: Import datetime library.
• Line #2: Unix time which is seconds since 1970-01-01.
• Line #3: Converts this to a unix time object, check with: type(value)
• Line #4: Prints in the same format as strp.

Bonus

To save the date to a string then print it, use this:

my_date = f"{value:%Y-%m-%d %H:%M:%S}"
print(my_date)

What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties

1. inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx

2. Add the event listeners etc..

That is because you have continuous text, means single long word without space. To break it add word-break: break-all;

.submenu div p {
    color:#fff;
    margin: 0;
    padding:0;
    width:100%;
    position: relative; word-break: break-all; background:red
}

DEMO

This should do the work:

sed -e 's/[ \t]+/\n/g'

[ \t] means a space OR an tab. If you want any kind of space, you could also use \s.

[ \t]+ means as many spaces OR tabs as you want (but at least one)

s/x/y/ means replace the pattern x by y (here \n is a new line)

The g at the end means that you have to repeat as many times it occurs in every line.

You can work around this by setting the X-UA-Compatible meta header for the specific version of IE you are debugging with. This will change the Browser Mode to the version you specify in the header.

For example:

<meta http-equiv="X-UA-Compatible" content="IE=9" />

In order for the Browser Mode to update on the Developer Tools, you must close [the Developer Tools] and reopen again. This will switch to that specific version.

Switching from a minor version to a greater version will work just fine by refreshing, but if you want to switch back from a greater version to a minor version, such as from 9 to 7, you would need to open a new tab and load the page again.

Here's a screenshot:

Here is a little improvement to the answer from https://stackoverflow.com/users/318563/o-o

    var dd  = this.getDate().toString();
    return (dd[1]?dd:"0"+dd[0]) + delimiter + (mm[1]?mm:"0"+mm[0]) + delimiter +yyyy  ; // padding
};

Hope to be helpfull for anyone!

You could also use the Executors object to create an ExecutorService thread pool. Then use the invokeAll method to run each of your threads and retrieve Futures. This will block until all have finished execution. Your other option would be to execute each one using the pool and then call awaitTermination to block until the pool is finished executing. Just be sure to call shutdown() when you're done adding tasks.

Turns out I don't have enough reputation to put this as a comment, which would be a more appropriate place for this:

Re. AllBlackt's answer, if you prefer Ansible's multiline format you need to adjust the quoting for state (I spent a few minutes working this out, so hopefully this speeds someone else up),

- stat:
    path: "/etc/nologin"
  register: p

- name: create fake 'nologin' shell
  file:
    path: "/etc/nologin"
    owner: root
    group: sys
    mode: 0555
    state: '{{ "file" if  p.stat.exists else "touch" }}'

I think this is important to consider for cross-platform execution, i.e. as a CYA. :)

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

This is directly quoted from Python Software Foundation 2.7.x.

var oldString = "stackoverflow";
var str=oldString.replace(/stackover/g,"NO");
$scope.newString= str;

It works for me. Use an intermediate variable.

I liked the last comment which used openssl_random_pseudo_bytes, but it wasn't a solution for me as I still had to remove the characters I didn't want, and I wasn't able to get a set length string. Here is my solution...

function rndStr($len = 20) {
    $rnd='';
    for($i=0;$i<$len;$i++) {
        do {
            $byte = openssl_random_pseudo_bytes(1);
            $asc = chr(base_convert(substr(bin2hex($byte),0,2),16,10));
        } while(!ctype_alnum($asc));
        $rnd .= $asc;
    }
    return $rnd;
}

Check if you did compress the driver or folder in where you put the .mdf file.

If so, plesae goto the driver or folder, change the compress option by

Properties -> Advanced and unticked the “Compress contents to save disk space” checkbox.

After above things, you should be able to start the service again.

Git doesn't store file permissions other than executable scripts. Consider using something like git-cache-meta to save file ownership and permissions.

Git can only store two types of modes: 755 (executable) and 644 (not executable). If your file was 444 git would store it has 644.

Check out some of the jQuery plugins for other implementations of a dialog. Cluetip appears to be a feature-rich tooltip/dialog style plug-in. The 4th demo sounds similar to what you are trying to do (although I see that it doesn't have the precise positioning option that you're looking for.)

Same Problem I had... I was writing all the script in a seperate file and was adding it through tag into the end of the HTML file after body tag. After moving the the tag inside the body tag it works fine. before :

</body>
<script>require('../script/viewLog.js')</script>

after :

<script>require('../script/viewLog.js')</script>
</body>

I'm not sure that I understand what you mean by "rights of ownership".

If User B owns a stored procedure, User B can grant User A permission to run the stored procedure

GRANT EXECUTE ON b.procedure_name TO a

User A would then call the procedure using the fully qualified name, i.e.

BEGIN
  b.procedure_name( <<list of parameters>> );
END;

Alternately, User A can create a synonym in order to avoid having to use the fully qualified procedure name.

CREATE SYNONYM procedure_name FOR b.procedure_name;

BEGIN
  procedure_name( <<list of parameters>> );
END;

Some answers don't take into account the OP wants a array of values

Other answers don't work well if your Model has thousands of records

That said, I think a good answer is:

    Model.uniq.select(:ratings).map(&:ratings)
    => "SELECT DISTINCT ratings FROM `models` " 

Because, first you generate a array of Model (with diminished size because of the select), then you extract the only attribute those selected models have (ratings)

This got bumped to the top because of an edit ... The answers have gotten a bit stale, and not as useful today as another solution has been added to the standard.

There is now an "all" shorthand property.

#elementId select.funTimes {
   all: initial;
}

This sets all css properties to their initial value ... note some of the initial values are inherit; Resulting in some formatting still taking place on the element.

Because of that pause required when reading the code or reviewing it in the future, don't use it unless you most as the review process is a point where errors/bugs can be made! when editing the page. But clearly if there are a large number of properties that need to be reset, then "all" is the way to go.

So this is my first answer here, and because I needed something similar I did with pseudo elements for 2 inner shadows, and an extra DIV for an upper outer shadow. Don't know if this is the best solutions but maybe it will help someone.

HTML

<div class="shadow-block">
    <div class="shadow"></div>
    <div class="overlay">
        <div class="overlay-inner">
            content here
        </div>
    </div>
</div>

CSS

.overlay {
    background: #f7f7f4;
    height: 185px;
    overflow: hidden;
    position: relative;
    width: 100%; 
}

.overlay:before {
    border-radius: 50% 50% 50% 50%;
    box-shadow: 0 0 50px 2px rgba(1, 1, 1, 0.6);
    content: " ";
    display: block;
    margin: 0 auto;
    width: 80%;
}

.overlay:after {
    border-radius: 50% 50% 50% 50%;
    box-shadow: 0 0 70px 5px rgba(1, 1, 1, 0.5);
    content: "-";
    display: block;
    margin: 0 auto;
    position: absolute;
    bottom: -65px;
    left: -50%;
    right: -50%;
    width: 80%;
}

.shadow {
    position: relative;
    width:100%;
    height:8px;
    margin: 0 0 -22px 0;
    -webkit-box-shadow: 0px 0px 50px 3px rgba(1, 1, 1, 0.6);
    box-shadow: 0px 0px 50px 3px rgba(1, 1, 1, 0.6);
    border-radius: 50%;
}

I wasn't able to replicate your bug:

var message = new MailMessage();

message.To.Add("[email protected]");
message.To.Add("[email protected]");

message.From = new MailAddress("[email protected]");
message.Subject = "Test";
message.Body = "Test";

var client = new SmtpClient("localhost", 25);
client.Send(message);

Dumping the contents of the To: MailAddressCollection:

MailAddressCollection (2 items)
DisplayName User Host Address

user example.com [email protected]
user2 example.com [email protected]

And the resulting e-mail as caught by smtp4dev:

Are you sure there's not some other issue going on with your code or SMTP server?

The coordinate system on the screen is left-handed, i.e. the x coordinate increases from left to right and the y coordinate increases from top to bottom. The origin, O(0, 0) is at the upper left corner of the screen.

A clockwise rotation around the origin of a point with coordinates (x, y) is given by the following equations:

where (x', y') are the coordinates of the point after rotation and angle theta, the angle of rotation (needs to be in radians, i.e. multiplied by: PI / 180).

To perform rotation around a point different from the origin O(0,0), let's say point A(a, b) (pivot point). Firstly we translate the point to be rotated, i.e. (x, y) back to the origin, by subtracting the coordinates of the pivot point, (x - a, y - b). Then we perform the rotation and get the new coordinates (x', y') and finally we translate the point back, by adding the coordinates of the pivot point to the new coordinates (x' + a, y' + b).

Following the above description:

a 2D clockwise theta degrees rotation of point (x, y) around point (a, b) is:

Using your function prototype: (x, y) -> (p.x, p.y); (a, b) -> (cx, cy); theta -> angle:

POINT rotate_point(float cx, float cy, float angle, POINT p){

     return POINT(cos(angle) * (p.x - cx) - sin(angle) * (p.y - cy) + cx,
                  sin(angle) * (p.x - cx) + cos(angle) * (p.y - cy) + cy);
}

Similar idea to yeh answer, just minimalist alternative.

You can include any layout file in other layout file as-

             <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="10dp"
                android:layout_marginRight="30dp" >

                <include
                    android:id="@+id/frnd_img_file"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    layout="@layout/include_imagefile"/>

                <include
                    android:id="@+id/frnd_video_file"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    layout="@layout/include_video_lay" />

                <ImageView
                    android:id="@+id/downloadbtn"
                    android:layout_width="30dp"
                    android:layout_height="30dp"
                    android:layout_centerInParent="true"
                    android:src="@drawable/plus"/>
            </RelativeLayout>

here the layout files in include tag are other .xml layout files in the same res folder.

I know it's old but I wanted to add my (preferred) flavour to this.

I think a pretty readable way to achieve this is to pass the topicId to a function, which in turn uses the argument to reference the topic ID internally. This value won't change even if topicId in the outside will be changed shortly after.

var topicId = xmlhttp.responseText;
var fDelayed = function(tid) {
  return function() {
    postinsql(tid);
  };
}
setTimeout(fDelayed(topicId),4000);

or short:

var topicId = xmlhttp.responseText;
setTimeout(function(tid) {
  return function() { postinsql(tid); };
}(topicId), 4000);

http://forums.iis.net/t/1187650.aspx has the answer. Setting the iis authentication to appliction pool identity will resolve this.

In IIS Authentication, Anonymous Authentication was set to "Specific User". When I changed it to Application Pool, I can access the site.

To set, click on your website in IIS and double-click "Authentication". Right-click on "Anonymous Authentication" and click "Edit..." option. Switch from "Specific User" to "Application pool identity". Now you should be able to set file and folder permissions using the IIS AppPool\{Your App Pool Name}.

The question as answered by Daniel is perfctly fine. I wanted to leave a note regarding NULLS. We should be carefull about using NOT IN operator when a column contains NULL values. You won't get any output if your column contains NULL values and you are using the NOT IN operator. This is how it's explained over here http://www.oraclebin.com/2013/01/beware-of-nulls.html , a very good article which I came across and thought of sharing it.

This worked for me:

byte[] bfoo = (byte[])foo;

foo is an Object that I'm 100% certain that is a byte array.

Try this below code

<?php
$file = 'dummy.pdf';
$filename = 'dummy.pdf';
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
header('Accept-Ranges: bytes');
@readfile($file);
?>

In the interpreter its easy to restart it and fix such problems. If you don't want to restart the interpreter, there is another way to fix it:

Python 2.6.6 (r266:84292, Dec 27 2010, 00:02:40)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> l = [1,2,3]
>>> sum(l)
6
>>> sum = 0 # oops! shadowed a builtin!
>>> sum(l)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable
>>> import sys
>>> sum = sys.modules['__builtin__'].sum # -- fixing sum
>>> sum(l)
6

This also comes in handy if you happened to assign a value to any other builtin, like dict or list

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Step 1 : import android.*;

Step 2 : clean your project

Step 3 : Enjoy !!!

you can do it using the format function, here is a sample:

Format(mydate, "yyyy-MM-dd HH:mm:ss")

I have found a solution which helped me to get it done. Setting cache-view="false" on ion-view tag resolved my problem.

<ion-view cache-view="false" view-title="My Title!">

You use an insert trigger - inside the trigger, inserted row items will be exposed as a logical table INSERTED, which has the same column layout as the table the trigger is defined on.

Delete triggers have access to a similar logical table called DELETED.

Update triggers have access to both an INSERTED table that contains the updated values and a DELETED table that contains the values to be updated.

For user check, just post get the access token as accessToken and post it and get the response

https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=accessToken

you can try in address bar in browsers too, use httppost and response in java also

response will be like

From a blog I found:

"This [git-credential-cache] doesn’t work for Windows systems as git-credential-cache communicates through a Unix socket."

Git for Windows

Since msysgit has been superseded by Git for Windows, using Git for Windows is now the easiest option. Some versions of the Git for Windows installer (e.g. 2.7.4) have a checkbox during the install to enable the Git Credential Manager. Here is a screenshot:

Still using msysgit? For msysgit versions 1.8.1 and above

The wincred helper was added in msysgit 1.8.1. Use it as follows:

git config --global credential.helper wincred

For msysgit versions older than 1.8.1

First, download git-credential-winstore and install it in your git bin directory.

Next, make sure that the directory containing git.cmd is in your Path environment variable. The default directory for this is C:\Program Files (x86)\Git\cmd on a 64-bit system or C:\Program Files\Git\cmd on a 32-bit system. An easy way to test this is to launch a command prompt and type git. If you don't get a list of git commands, then it's not set up correctly.

Finally, launch a command prompt and type:

git config --global credential.helper winstore

Or you can edit your .gitconfig file manually:

[credential]
    helper = winstore

Once you've done this, you can manage your git credentials through Windows Credential Manager which you can pull up via the Windows Control Panel.

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

I thought i'd expand on the above answer by talking about how you'd fit modules together into an application. I'd read about this in the doug crockford book but being new to javascript it was all still a bit mysterious.

I come from a c# background so have added some terminology I find useful from there.

Html

You'll have some kindof top level html file. It helps to think of this as your project file. Every javascript file you add to the project wants to go into this, unfortunately you dont get tool support for this (I'm using IDEA).

You need add files to the project with script tags like this:

        <script type="text/javascript" src="app/native/MasterFile.js" /></script>
        <script type="text/javascript" src="app/native/SomeComponent.js" /></script>

It appears collapsing the tags causes things to fail - whilst it looks like xml it's really something with crazier rules!

Namespace file

MasterFile.js

myAppNamespace = {};

that's it. This is just for adding a single global variable for the rest of our code to live in. You could also declare nested namespaces here (or in their own files).

Module(s)

SomeComponent.js

myAppNamespace.messageCounter= (function(){

    var privateState = 0;

    var incrementCount = function () {
        privateState += 1;
    };

    return function (message) {
        incrementCount();
        //TODO something with the message! 
    }
})();

What we're doing here is assigning a message counter function to a variable in our application. It's a function which returns a function which we immediately execute.

Concepts

I think it helps to think of the top line in SomeComponent as being the namespace where you are declaring something. The only caveat to this is all your namespaces need to appear in some other file first - they are just objects rooted by our application variable.

I've only taken minor steps with this at the moment (i'm refactoring some normal javascript out of an extjs app so I can test it) but it seems quite nice as you can define little functional units whilst avoiding the quagmire of 'this'.

You can also use this style to define constructors by returning a function which returns an object with a collection of functions and not calling it immediately.

You can use string.punctuation and any function like this

import string
invalidChars = set(string.punctuation.replace("_", ""))
if any(char in invalidChars for char in word):
    print "Invalid"
else:
    print "Valid"

With this line

invalidChars = set(string.punctuation.replace("_", ""))

we are preparing a list of punctuation characters which are not allowed. As you want _ to be allowed, we are removing _ from the list and preparing new set as invalidChars. Because lookups are faster in sets.

any function will return True if atleast one of the characters is in invalidChars.

Edit: As asked in the comments, this is the regular expression solution. Regular expression taken from https://stackoverflow.com/a/336220/1903116

word = "Welcome"
import re
print "Valid" if re.match("^[a-zA-Z0-9_]*$", word) else "Invalid"

if the project is not a big ,

1- change the name of folder project

2- make a new project with the same project (before renaming)

3- add existing files from the old project to the new project (totally same , same folders , same names , ...)

4- open the the new project file (as xml ) and the old project

5- copy the new project file (xml content ) and paste it in the old project file

6- delete the old project

7- rename the old folder project to old name

Or you could just create a link element and click it...

var evLink = document.createElement('a');
evLink.href = 'http://' + strUrl;
evLink.target = '_blank';
document.body.appendChild(evLink);
evLink.click();
// Now delete it
evLink.parentNode.removeChild(evLink);

This shouldn't be blocked by any popup blockers... Hopefully.

The way a cherry-pick works is by taking the diff a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying it to your current branch.

So, if a commit has two or more parents, it also represents two or more diffs - which one should be applied?

You're trying to cherry pick fd9f578, which was a merge with two parents. So you need to tell the cherry-pick command which one against which the diff should be calculated, by using the -m option. For example, git cherry-pick -m 1 fd9f578 to use parent 1 as the base.

I can't say for sure for your particular situation, but using git merge instead of git cherry-pick is generally advisable. When you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m into that one commit. You lose all their history, and glom together all their diffs. Your call.

        .nullsFirst(String::compareToIgnoreCase); 

private static Comparator<Metadata> metadataComparator = Comparator
        .comparing(Metadata::getName, nullSafeStringComparator)
        .thenComparing(Metadata::getValue, nullSafeStringComparator);

public int compareTo(Metadata that) {
    return metadataComparator.compare(this, that);
}

        // It needs to release key after pressing
        rb.keyRelease(KeyEvent.VK_A);
        rb.keyRelease(KeyEvent.VK_CONTROL);
        Thread.sleep(3000);
    }
}

To demonstrate, consider the following set, which holds different Person objects:

Set<Person> people = new HashSet<Person>();
people.add(new Person("Tharindu", 10));
people.add(new Person("Martin", 20));
people.add(new Person("Fowler", 30));

Person Model Class

public class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    //TODO - getters,setters ,overridden toString & compareTo methods

}

1. The for statement has a form designed for iteration through Collections and arrays .This form is sometimes referred to as the enhanced for statement, and can be used to make your loops more compact and easy to read.

for(Person p:people){
  System.out.println(p.getName());
}

2. Java 8 - java.lang.Iterable.forEach(Consumer)

people.forEach(p -> System.out.println(p.getName()));

default void forEach(Consumer<? super T> action)

Performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception. Unless otherwise specified by the implementing class, actions are performed in the order of iteration (if an iteration order is specified). Exceptions thrown by the action are relayed to the caller. Implementation Requirements:

The default implementation behaves as if: 

for (T t : this)
     action.accept(t);

Parameters: action - The action to be performed for each element

Throws: NullPointerException - if the specified action is null

Since: 1.8

In a Python interpreter or script, you can do

import site
site.getsitepackages() # List of global package locations

and

site.getusersitepackages() # String for user-specific package location

For locations third-party packages (those not in the core Python distribution) are installed to.

On my Homebrew-installed Python on macOS, the former outputs

['/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages'],

which canonicalizes to the same path output by pip show, as mentioned in a previous answer:

$ readlink -f /usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages
/usr/local/lib/python3.7/site-packages

I was able to solve this by removing the [&TotalPages] builtin field from the bottom. The time when down from minutes to less than a second.

Something odd that I could not determined was having impact on the calculation of total pages.

I was using SSRS 2012.

Yet another way of obtaining the IP Address from a NIC, using Python.

I had this as part of an app that I developed long time ago, and I didn't wanted to simply git rm script.py. So, here I provide the approach, using subprocess and list comprehensions for the sake of functional approach and less lines of code:

import subprocess as sp

__version__ = "v1.0"                                                            
__author__ = "@ivanleoncz"

def get_nic_ipv4(nic):                                                          
    """
        Get IP address from a NIC.                                              

        Parameter
        ---------
        nic : str
            Network Interface Card used for the query.                          

        Returns                                                                 
        -------                                                                 
        ipaddr : str
            Ipaddress from the NIC provided as parameter.                       
    """                                                                         
    result = None                                                               
    try:                                                                        
        result = sp.check_output(["ip", "-4", "addr", "show", nic],             
                                                  stderr=sp.STDOUT)
    except Exception:
        return "Unkown NIC: %s" % nic
    result = result.decode().splitlines()
    ipaddr = [l.split()[1].split('/')[0] for l in result if "inet" in l]        
    return ipaddr[0]

Additionally, you can use a similar approach for obtaining a list of NICs:

def get_nics():                                                                 
    """                                                                         
        Get all NICs from the Operating System.                                 

        Returns                                                                 
        -------                                                                 
        nics : list                                                             
            All Network Interface Cards.                                        
    """                                                                         
    result = sp.check_output(["ip", "addr", "show"])                            
    result = result.decode().splitlines()                                       
    nics = [l.split()[1].strip(':') for l in result if l[0].isdigit()]          
    return nics                                                

Here's the solution as a Gist.

And you would have something like this:

$ python3
Python 3.6.7 (default, Oct 22 2018, 11:32:17) 
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 
>>> 
>>> import helpers
>>> 
>>> helpers.get_nics()
['lo', 'enp1s0', 'wlp2s0', 'docker0']
>>> helpers.get_nic_ipv4('docker0')
'172.17.0.1'
>>> helpers.get_nic_ipv4('docker2')
'Unkown NIC: docker2'

There are many ways to filter for element ancestors.

if ($elem.closest('.parentClass').length /* > 0*/) {/*...*/}
if ($elem.parents('.parentClass').length /* > 0*/) {/*...*/}
if ($elem.parents().hasClass('parentClass')) {/*...*/}
if ($('.parentClass').has($elem).length /* > 0*/) {/*...*/}
if ($elem.is('.parentClass *')) {/*...*/} 

Beware, closest() method includes element itself while checking for selector.

Alternatively, if you have a unique selector matching the $elem, e.g #myElem, you can use:

if ($('.parentClass:has(#myElem)').length /* > 0*/) {/*...*/}
if(document.querySelector('.parentClass #myElem')) {/*...*/}

If you want to match an element depending any of its ancestor class for styling purpose only, just use a CSS rule:

.parentClass #myElem { /* CSS property set */ }

When you make a call to using namespace <some_namespace>; all symbols in that namespace will become visible without adding the namespace prefix. A symbol may be for instance a function, class or a variable.

E.g. if you add using namespace std; you can write just cout instead of std::cout when calling the operator cout defined in the namespace std.

This is somewhat dangerous because namespaces are meant to be used to avoid name collisions and by writing using namespace you spare some code, but loose this advantage. A better alternative is to use just specific symbols thus making them visible without the namespace prefix. Eg:

#include <iostream>
using std::cout;

int main() {
  cout << "Hello world!";
  return 0;
}

Yes but it depends what you want to execute:

E.g.

try {
   a();
   b();
}
catch(Exception $e){
}

c();

c() will always be executed. But if a() throws an exception, b() is not executed.

Only put the stuff in to the try block that is depended on each other. E.g. b depends on some result of a it makes no sense to put b after the try-catch block.

If you want to clear all the headers as well as the data, for example if you are switching between 2 totally different databases with different fields, therefore different columns and column headers, I found the following to work. Otherwise when you switch you have the columns/ fields from both databases showing in the grid.

dataTable.Dispose();//get rid of existing datatable
dataTable = new DataTable();//create new datatable

datagrid.DataSource = dataTable;//clears out the datagrid with empty datatable
//datagrid.Refresh(); This does not seem to be neccesary

dataadapter.Fill(dataTable); //assumming you set the adapter with new data               
datagrid.DataSource = dataTable; 

Another way is to get the row index and then use df.loc or df.at.

# get row index 'label' from row number 'irow'
label = df.index.values[irow] 
df.at[label, 'COL_NAME'] = x

The new Network framework has failable initializers for struct IPv4Address and struct IPv6Address which handle the IP address portion very easily. Doing this in IPv6 with a regex is tough with all the shortening rules.

Unfortunately I don't have an elegant answer for hostname.

Note that Network framework is recent, so it may force you to compile for recent OS versions.

import Network
let tests = ["192.168.4.4","fkjhwojfw","192.168.4.4.4","2620:3","2620::33"]

for test in tests {
    if let _ = IPv4Address(test) {
        debugPrint("\(test) is valid ipv4 address")
    } else if let _ = IPv6Address(test) {
        debugPrint("\(test) is valid ipv6 address")
    } else {
        debugPrint("\(test) is not a valid IP address")
    }
}

output:
"192.168.4.4 is valid ipv4 address"
"fkjhwojfw is not a valid IP address"
"192.168.4.4.4 is not a valid IP address"
"2620:3 is not a valid IP address"
"2620::33 is valid ipv6 address"

Try this, works for me.. simple

Assume that your resource file name is "TestResource.resx", and you want to pass key dynamically then,

string resVal = TestResource.ResourceManager.GetString(dynamicKeyVal);

Add Namespace

using System.Resources;

EDIT based on comments:

If you have line breaks in your result set and want to remove them, make your query this way:

SELECT
    REPLACE(REPLACE(YourColumn1,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn2,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn3,CHAR(13),' '),CHAR(10),' ')
   --^^^^^^^^^^^^^^^           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   --only add the above code to strings that are having line breaks, not to numbers or dates
   FROM YourTable...
   WHERE ...

This will replace all the line breaks with a space character.

Run this to "get" all characters permitted in a char() and varchar():

;WITH AllNumbers AS
(
    SELECT 1 AS Number
    UNION ALL
    SELECT Number+1
        FROM AllNumbers
        WHERE Number+1<256
)
SELECT Number AS ASCII_Value,CHAR(Number) AS ASCII_Char FROM AllNumbers
OPTION (MAXRECURSION 256)

OUTPUT:

ASCII_Value ASCII_Char

If you want easy and simple, you might also want to look at Fabric. It's an automated deployment tool like Ruby's Capistrano, but simpler and of course for Python. It's build on top of Paramiko.

You might not want to do 'automated deployment' but Fabric would suit your use case perfectly none the less. To show you how simple Fabric is: the fab file and command for your script would look like this (not tested, but 99% sure it will work):

fab_putfile.py:

from fabric.api import *

env.hosts = ['THEHOST.com']
env.user = 'THEUSER'
env.password = 'THEPASSWORD'

def put_file(file):
    put(file, './THETARGETDIRECTORY/') # it's copied into the target directory

Then run the file with the fab command:

fab -f fab_putfile.py put_file:file=./path/to/my/file

And you're done! :)

Assuming the key is contained inside the <appSettings> node:

ConfigurationSettings.AppSettings["theKey"];

As for "writing" - put simply, dont.

The web.config is not designed for that, if you're going to be changing a value constantly, put it in a static helper class.

You need a split function:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create Function [dbo].[udf_Split]
(   
    @DelimitedList nvarchar(max)
    , @Delimiter nvarchar(2) = ','
)
RETURNS TABLE 
AS
RETURN 
    (
    With CorrectedList As
        (
        Select Case When Left(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
            + @DelimitedList
            + Case When Right(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
            As List
            , Len(@Delimiter) As DelimiterLen
        )
        , Numbers As 
        (
        Select TOP( Coalesce(DataLength(@DelimitedList)/2,0) ) Row_Number() Over ( Order By c1.object_id ) As Value
        From sys.columns As c1
            Cross Join sys.columns As c2
        )
    Select CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen As Position
        , Substring (
                    CL.List
                    , CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen     
                    , CharIndex(@Delimiter, CL.list, N.Value + 1)                           
                        - ( CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen ) 
                    ) As Value
    From CorrectedList As CL
        Cross Join Numbers As N
    Where N.Value <= DataLength(CL.List) / 2
        And Substring(CL.List, N.Value, CL.DelimiterLen) = @Delimiter
    )

With your split function, you would then use Cross Apply to get the data:

Select T.Col1, T.Col2
    , Substring( Z.Value, 1, Charindex(' = ', Z.Value) - 1 ) As AttributeName
    , Substring( Z.Value, Charindex(' = ', Z.Value) + 1, Len(Z.Value) ) As Value
From Table01 As T
    Cross Apply dbo.udf_Split( T.Col3, '|' ) As Z

You can let PHP do a POST, but then your php will get the return, with all sorts of complications. I think the simplest would be to actually let the user do the POST.

So, kind-of what you suggested, you'll get indeed this part:

Customer fill detail in Page A, then in Page B we create another page show all the customer detail there, click a CONFIRM button then POST to Page C.

But you can actually do a javascript submit on page B, so there is no need for a click. Make it a "redirecting" page with a loading animation, and you're set.

Modifying, or more correctly, adding additional HTTP headers is a great code debugging tool if nothing else.

When a URL request returns a redirect or an image there is no html "page" to temporarily write the results of debug code to - at least not one that is visible in a browser.

One approach is to write the data to a local log file and view that file later. Another is to temporarily add HTTP headers reflecting the data and variables being debugged.

I regularly add extra HTTP headers like X-fubar-somevar: or X-testing-someresult: to test things out - and have found a lot of bugs that would have otherwise been very difficult to trace.

Ok well this might work for you, a function that takes a path and returns an array of file names in the folder. You could use an if statement to get just the excel files when looping through the array.

Function listfiles(ByVal sPath As String)

    Dim vaArray     As Variant
    Dim i           As Integer
    Dim oFile       As Object
    Dim oFSO        As Object
    Dim oFolder     As Object
    Dim oFiles      As Object

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(sPath)
    Set oFiles = oFolder.Files

    If oFiles.Count = 0 Then Exit Function

    ReDim vaArray(1 To oFiles.Count)
    i = 1
    For Each oFile In oFiles
        vaArray(i) = oFile.Name
        i = i + 1
    Next

    listfiles = vaArray

End Function

It would be nice if we could just access the files in the files object by index number but that seems to be broken in VBA for whatever reason (bug?).

Using header function for routing

<?php
     header('Location: B.php');
     exit();
?>

Suppose we want to route from A.php file to B.php than we have to take help of <button> or <a>. Lets see an example

<?php
if(isset($_GET['go_to_page_b'])) {
    header('Location: B.php');
    exit();

}
?>

<p>I am page A</p>
<button name='go_to_page_b'>Page B</button>

B.php

<p> I am Page B</p>

Simply removing @RequestBody annotation solves the problem (tested on Spring Boot 2):

@RestController
public class MyController {

    @PostMapping
    public void method(@Valid RequestDto dto) {
       // method body ...
    }
}

//program to form1 to form2
private void button1_Click(object sender, EventArgs e)
{
    //MessageBox.Show("Welcome Admin");
    Form2 frm = new Form2();
    frm.Show();
    this.Hide();          
}

tl;dr

• "Foo" and "bar" as metasyntactic variables were popularised by MIT and DEC, the first references are in work on LISP and PDP-1 and Project MAC from 1964 onwards.

• Many of these people were in MIT's Tech Model Railroad Club, where we find the first documented use of "foo" in tech circles in 1959 (and a variant in 1958).

• Both "foo" and "bar" (and even "baz") were well known in popular culture, especially from Smokey Stover and Pogo comics, which will have been read by many TMRC members.

• Also, it seems likely the military FUBAR contributed to their popularity.

The use of lone "foo" as a nonsense word is pretty well documented in popular culture in the early 20th century, as is the military FUBAR. (Some background reading: FOLDOC FOLDOC Jargon File Jargon File Wikipedia RFC3092)

OK, so let's find some references.

STOP PRESS! After posting this answer, I discovered this perfect article about "foo" in the Friday 14th January 1938 edition of The Tech ("MIT's oldest and largest newspaper & the first newspaper published on the web"), Volume LVII. No. 57, Price Three Cents:

On Foo-ism

The Lounger thinks that this business of Foo-ism has been carried too far by its misguided proponents, and does hereby and forthwith take his stand against its abuse. It may be that there's no foo like an old foo, and we're it, but anyway, a foo and his money are some party. (Voice from the bleachers- "Don't be foo-lish!")

As an expletive, of course, "foo!" has a definite and probably irreplaceable position in our language, although we fear that the excessive use to which it is currently subjected may well result in its falling into an early (and, alas, a dark) oblivion. We say alas because proper use of the word may result in such happy incidents as the following.

It was an 8.50 Thermodynamics lecture by Professor Slater in Room 6-120. The professor, having covered the front side of the blackboard, set the handle that operates the lift mechanism, turning meanwhile to the class to continue his discussion. The front board slowly, majestically, lifted itself, revealing the board behind it, and on that board, writ large, the symbols that spelled "FOO"!

The Tech newspaper, a year earlier, the Letter to the Editor, September 1937:

By the time the train has reached the station the neophytes are so filled with the stories of the glory of Phi Omicron Omicron, usually referred to as Foo, that they are easy prey.

...

It is not that I mind having lost my first four sons to the Grand and Universal Brotherhood of Phi Omicron Omicron, but I do wish that my fifth son, my baby, should at least be warned in advance.

Hopefully yours,

Indignant Mother of Five.

And The Tech in December 1938:

General trend of thought might be best interpreted from the remarks made at the end of the ballots. One vote said, '"I don't think what I do is any of Pulver's business," while another merely added a curt "Foo."

The first documented "foo" in tech circles is probably 1959's Dictionary of the TMRC Language:

FOO: the sacred syllable (FOO MANI PADME HUM); to be spoken only when under inspiration to commune with the Deity. Our first obligation is to keep the Foo Counters turning.

These are explained at FOLDOC. The dictionary's compiler Pete Samson said in 2005:

Use of this word at TMRC antedates my coming there. A foo counter could simply have randomly flashing lights, or could be a real counter with an obscure input.

And from 1996's Jargon File 4.0.0:

Earlier versions of this lexicon derived 'baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout 'Bazz Fazz!' or 'Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."

A year before the TMRC dictionary, 1958's MIT Voo Doo Gazette ("Humor suplement of the MIT Deans' office") (PDF) mentions Foocom, in "The Laws of Murphy and Finagle" by John Banzhaf (an electrical engineering student):

Further research under a joint Foocom and Anarcom grant expanded the law to be all embracing and universally applicable: If anything can go wrong, it will!

Also 1964's MIT Voo Doo (PDF) references the TMRC usage:

Yes! I want to be an instant success and snow customers. Send me a degree in: ...

• Foo Counters

• Foo Jung

Let's find "foo", "bar" and "foobar" published in code examples.

So, Jargon File 4.4.7 says of "foobar":

Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972.

The first published reference I can find is from February 1964, but written in June 1963, The Programming Language LISP: its Operation and Applications by Information International, Inc., with many authors, but including Timothy P. Hart and Michael Levin:

Thus, since "FOO" is a name for itself, "COMITRIN" will treat both "FOO" and "(FOO)" in exactly the same way.

Also includes other metasyntactic variables such as: FOO CROCK GLITCH / POOT TOOR / ON YOU / SNAP CRACKLE POP / X Y Z

I expect this is much the same as this next reference of "foo" from MIT's Project MAC in January 1964's AIM-064, or LISP Exercises by Timothy P. Hart and Michael Levin:

car[((FOO . CROCK) . GLITCH)]

It shares many other metasyntactic variables like: CHI / BOSTON NEW YORK / SPINACH BUTTER STEAK / FOO CROCK GLITCH / POOT TOOP / TOOT TOOT / ISTHISATRIVIALEXCERCISE / PLOOP FLOT TOP / SNAP CRACKLE POP / ONE TWO THREE / PLANE SUB THRESHER

For both "foo" and "bar" together, the earliest reference I could find is from MIT's Project MAC in June 1966's AIM-098, or PDP-6 LISP by none other than Peter Samson:

EXPLODE, like PRIN1, inserts slashes, so (EXPLODE (QUOTE FOO/ BAR)) PRIN1's as (F O O // / B A R) or PRINC's as (F O O / B A R).

Some more recallations.

@Walter Mitty recalled on this site in 2008:

I second the jargon file regarding Foo Bar. I can trace it back at least to 1963, and PDP-1 serial number 2, which was on the second floor of Building 26 at MIT. Foo and Foo Bar were used there, and after 1964 at the PDP-6 room at project MAC.

John V. Everett recalls in 1996:

When I joined DEC in 1966, foobar was already being commonly used as a throw-away file name. I believe fubar became foobar because the PDP-6 supported six character names, although I always assumed the term migrated to DEC from MIT. There were many MIT types at DEC in those days, some of whom had worked with the 7090/7094 CTSS. Since the 709x was also a 36 bit machine, foobar may have been used as a common file name there.

Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again.

It was also common to use foo to fill a buffer when editing with TECO. The text string to exactly fill one disk block was IFOO$HXA127GA$$. Almost all of the PDP-6/10 programmers I worked with used this same command string.

Daniel P. B. Smith in 1998:

Dick Gruen had a device in his dorm room, the usual assemblage of B-battery, resistors, capacitors, and NE-2 neon tubes, which he called a "foo counter." This would have been circa 1964 or so.

Robert Schuldenfrei in 1996:

The use of FOO and BAR as example variable names goes back at least to 1964 and the IBM 7070. This too may be older, but that is where I first saw it. This was in Assembler. What would be the FORTRAN integer equivalent? IFOO and IBAR?

Paul M. Wexelblat in 1992:

The earliest PDP-1 Assembler used two characters for symbols (18 bit machine) programmers always left a few words as patch space to fix problems. (Jump to patch space, do new code, jump back) That space conventionally was named FU: which stood for Fxxx Up, the place where you fixed Fxxx Ups. When spoken, it was known as FU space. Later Assemblers ( e.g. MIDAS allowed three char tags so FU became FOO, and as ALL PDP-1 programmers will tell you that was FOO space.

Bruce B. Reynolds in 1996:

On the IBM side of FOO(FU)BAR is the use of the BAR side as Base Address Register; in the middle 1970's CICS programmers had to worry out the various xxxBARs...I think one of those was FRACTBAR...

Here's a straight IBM "BAR" from 1955.

I haven't been able to find any references to foo bar as "inverted foo signal" as suggested in RFC3092 and elsewhere.

Here are a some of even earlier F00s but I think they're coincidences/false positives:

• 1959 "FOO 31 IBM-704 Bettis Plant Uses a least squares technique" U.S. Atomic Energy Commission

• 1960 FOO (FO Out, F1, F2, FOO, FOI) "Digital computer and control engineering"

• 1967 FOO?

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.

I don't like and understand things, which can be explained visually, by words.

This is how I solved this issue:

1. Change the .env file as follow

2. Never forget to restart the server after you change the .env file

Its very simple. Call one function inside another function with parameters.

    function fun1()
    {
     var a=10;
     var b=20;
     fun2(a,b); //calling function fun2() and passing 2 parameters
    }

   function fun2(num1,num2)
   {
    var sum;
    sum = num1+num2;
    return sum;
   }

   fun1(); //trigger function fun1

Sometimes you will need this :

 /*<![CDATA[*/
 /*]]>*/

and not only this :

 <![CDATA[
 ]]>

Actually this error occurs when server makes connection but can't build due to failure in identifying connection function identifier. This problem can be solved by typing connection function in code. For this I take a simple example. In this case function is con your may be different.

SqlCommand cmd = new SqlCommand("insert into ptb(pword,rpword) values(@a,@b)",con);

You can also do this as a one-liner:

df.drop(columns=['b', 'x']).assign(b=df['b'], x=df['x'])

If the order of the execution is not important and you need both some javascript AND some codebehind to be fired on an asp element, heres what you can do.

What you can take away from my example: I have a div covering the ASP control that I want both javascript and codebehind to be ran from. The div's onClick method AND the calendar's OnSelectionChanged event both get fired this way.

In this example, i am using an ASP Calendar control, and im controlling it from both javascript and codebehind:

Front end code:

        <div onclick="showHideModal();">
            <asp:Calendar 
                OnSelectionChanged="DatepickerDateChange" ID="DatepickerCalendar" runat="server" 
                BorderWidth="1px" DayNameFormat="Shortest" Font-Names="Verdana" 
                Font-Size="8pt" ShowGridLines="true" BackColor="#B8C9E1" BorderColor="#003E51" Width="100%"> 
                <OtherMonthDayStyle ForeColor="#6C5D34"> </OtherMonthDayStyle> 
                <DayHeaderStyle  ForeColor="black" BackColor="#D19000"> </DayHeaderStyle>
                <TitleStyle BackColor="#B8C9E1" ForeColor="Black"> </TitleStyle> 
                <DayStyle BackColor="White"> </DayStyle> 
                <SelectedDayStyle BackColor="#003E51" Font-Bold="True"> </SelectedDayStyle> 
            </asp:Calendar>
        </div>

Codebehind:

        protected void DatepickerDateChange(object sender, EventArgs e)
        {
            if (toFromPicked.Value == "MainContent_fromDate")
            {
                fromDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
            else
            {
                toDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
        }

Here's a function that gives you all subsets of the integers [0..n], not just the subsets of a given length:

from itertools import combinations, chain

def allsubsets(n):
    return list(chain(*[combinations(range(n), ni) for ni in range(n+1)]))

so e.g.

>>> allsubsets(3)
[(), (0,), (1,), (2,), (0, 1), (0, 2), (1, 2), (0, 1, 2)]

'Fraid so. I'd make an HTML page with a stylesheet, then use jQuery to apply the stylesheet to the style attr of each element. Something like this:

var styleAttributes = ['color','font-size']; // all the attributes you've applied in your stylesheet
for (i in styleAttributes) {
    $('body *').css(styleAttributes[i],function () {
        $(this).css(styleAttributes[i]);
    });
}

Then copy the DOM and use that in the email.

This problem is because you use uppercase suffix stuff.C rather than lowercase stuff.c when you compile it with Mingw GCC. For example, when you do like this:

gcc -o stuff stuff.C

then you will get the message: gcc: CreateProcess: No such file or directory

But if you do this:

 gcc -o stuff stuff.c

then it works. I just don't know why.

I think you are simply exchanging dumps and loads.

>>> import json
>>> data = [['apple', 'cat'], ['banana', 'dog'], ['pear', 'fish']]

The first returns as a (JSON encoded) string its data argument:

>>> encoded_str = json.dumps( data )
>>> encoded_str
'[["apple", "cat"], ["banana", "dog"], ["pear", "fish"]]'

The second does the opposite, returning the data corresponding to its (JSON encoded) string argument:

>>> decoded_data = json.loads( encoded_str )
>>> decoded_data
[[u'apple', u'cat'], [u'banana', u'dog'], [u'pear', u'fish']]
>>> decoded_data == data
True

I think you can use REGEXP instead of LIKE

SELECT trecord FROM `tbl` WHERE (trecord REGEXP '^ALA[0-9]')

If you want to set 777 permission to your created file than you can use the following method:

public void setPermission(File file) throws IOException{
    Set<PosixFilePermission> perms = new HashSet<>();
    perms.add(PosixFilePermission.OWNER_READ);
    perms.add(PosixFilePermission.OWNER_WRITE);
    perms.add(PosixFilePermission.OWNER_EXECUTE);

    perms.add(PosixFilePermission.OTHERS_READ);
    perms.add(PosixFilePermission.OTHERS_WRITE);
    perms.add(PosixFilePermission.OTHERS_EXECUTE);

    perms.add(PosixFilePermission.GROUP_READ);
    perms.add(PosixFilePermission.GROUP_WRITE);
    perms.add(PosixFilePermission.GROUP_EXECUTE);

    Files.setPosixFilePermissions(file.toPath(), perms);
}

Thanks to everyone's contributions to this question, I've come up with the following script. Change the values for $SvcName and $SvrName to suit your needs. This script will start the remote service if it is stopped, or stop it if it is started. And it uses the cool .WaitForStatus method to wait while the service responds.

#Change this values to suit your needs:
$SvcName = 'Spooler'
$SvrName = 'remotePC'

#Initialize variables:
[string]$WaitForIt = ""
[string]$Verb = ""
[string]$Result = "FAILED"
$svc = (get-service -computername $SvrName -name $SvcName)
Write-host "$SvcName on $SvrName is $($svc.status)"
Switch ($svc.status) {
    'Stopped' {
        Write-host "Starting $SvcName..."
        $Verb = "start"
        $WaitForIt = 'Running'
        $svc.Start()}
    'Running' {
        Write-host "Stopping $SvcName..."
        $Verb = "stop"
        $WaitForIt = 'Stopped'
        $svc.Stop()}
    Default {
        Write-host "$SvcName is $($svc.status).  Taking no action."}
}
if ($WaitForIt -ne "") {
    Try {  # For some reason, we cannot use -ErrorAction after the next statement:
        $svc.WaitForStatus($WaitForIt,'00:02:00')
    } Catch {
        Write-host "After waiting for 2 minutes, $SvcName failed to $Verb."
    }
    $svc = (get-service -computername $SvrName -name $SvcName)
    if ($svc.status -eq $WaitForIt) {$Result = 'SUCCESS'}
    Write-host "$Result`: $SvcName on $SvrName is $($svc.status)"
}

Of course, the account you run this under will need the proper privileges to access the remote computer and start and stop services. And when executing this against older remote machines, you might first have to install WinRM 3.0 on the older machine.

A different approach that I found ugly compared to the classic dict+append, but that works:

df = df.T

df[0] = ['1/1/2013', 'Smith','test',123]

df = df.T

df
Out[6]: 
       Date   Name Action   ID
0  1/1/2013  Smith   test  123

@RestController is composition of @Controller and @ResponseBody, if we are not using the @ResponseBody in Method signature then we need to use the @Restcontroller.

This method has been tested and worked with ASP.NET Core 3.1 and Visual Studio 2019.

    <binding protocol="http" bindingInformation="*:5737:localhost" />
    <binding protocol="https" bindingInformation="*:44320:*" />
</bindings>

Both links work:

• https://localhost:44320
• https://127.0.0.1:44320

Now if you want the app to work with the custom domain, just add the following line to the host file:

C:\Windows\System32\drivers\etc\hosts

127.0.0.1 customdomain

Now:

• https://customdomain:44320

NOTE: If your app works without SSL, change the protocol="http" part.

it's in there by default. It's the id field.

I just went through this myself and chose to set the default value at the reducer INIT function.

If you bind your select with redux then best not 'de-bind' it with a select default value that doesn't represent the actual value, instead set the value when you initialize the object.

In MySql, alice name may not work, therefore put the original column name in the CASE statement

 SELECT col1 as a, CASE WHEN col1 = 'test' THEN 'yes' END as value FROM table;

Sometimes above query also may return error, I don`t know why (I faced this problem in my two different development machine). Therefore put the CASE statement into the "(...)" as below:

SELECT col1 as a, (CASE WHEN col1 = 'test' THEN 'yes' END) as value FROM table;

Alternatively to count columns, count the separators between columns. I find this to be a good balance of brevity and ease to remember. Of course, this won't work if your data include the column separator.

head -n1 myfile.txt | grep -o " " | wc -l

Uses head -n1 to grab the first line of the file. Uses grep -o to to count all the spaces, and output each space found on a new line. Uses wc -l to count the number of lines.

Have a look at this article: Tracing python memory leaks

Also, note that the garbage collection module actually can have debug flags set. Look at the set_debug function. Additionally, look at this code by Gnibbler for determining the types of objects that have been created after a call.

The 60 you're passing is just the initial capacity for internal storage. It's a hint on how big you think it might be, yet of course it's not limited by that. If you need to preset values you'll have to set them yourself, e.g.:

for (int i = 0; i < 60; i++) {
    list.add(0);
}

You usually get this error if your tables use the InnoDB engine. In that case you would have to drop the foreign key, and then do the alter table and drop the column.

But the tricky part is that you can't drop the foreign key using the column name, but instead you would have to find the name used to index it. To find that, issue the following select:

SHOW CREATE TABLE region;

This should show you the name of the index, something like this:

CONSTRAINT region_ibfk_1 FOREIGN KEY (country_id) REFERENCES country (id) ON DELETE NO ACTION ON UPDATE NO ACTION

Now simply issue an:

alter table region drop foreign key region_ibfk_1;

And finally an:

alter table region drop column country_id;

And you are good to go!

You are most likely not using the correct credentials for the MySQL server. You also need to ensure the user you are connecting as has the correct privileges to view databases/tables, and that you can connect from your current location in network topographic terms (localhost).

try this css:

/* Show in default resolution screen*/
#container2 {

There are many ways how you can fix this issue, if you know the root of the issue.

Problem 1

Firstly, it may be a problem with your apache not having the mod_rewrite.c module installed or enabled.

For this reason, you would have to enable it as follows

1. Open up your console and type into it, this:

   sudo a2enmod rewrite

2. Restart your apache server.

   service apache2 restart

Problem 2

1. You may also, in addition to the above, if it does not work, have to change the override rule from the apache conf file (either apache2.conf, http.conf , or 000-default file).

2. Locate "Directory /var/www/"

3. Change the "Override None" to "Override All"

Problem 3

If you get an error stating rewrite module is not found, then probably your userdir module is not enabled. For this reason you need to enable it.

1. Type this into the console:

   sudo a2enmod userdir

2. Then try enabling the rewrite module if still not enabled (as mentioned above).

Used this approach for array of bytes:

Initially:

byte[] bytes = new byte[0];

Whenever required (Need to provide original length for extending):

Array.Resize<byte>(ref bytes, bytes.Length + requiredSize);

Reset:

Array.Resize<byte>(ref bytes, 0);

Typed List Method

Initially:

List<byte> bytes = new List<byte>();

Whenever required:

bytes.AddRange(new byte[length]);

Release/Clear:

bytes.Clear()

Both Promises and Observables help us dealing with asynchronous operations. They can call certain callbacks when these asynchronous operations are done.

Angular uses Observables which is from RxJS instead of promises for dealing with HTTP

Below are some important differences in promises & Observables.

I think you should try

data = {"shareInfo":[{"id":"1","a":"sss","b":"sss","question":"whi?"},
{"id":"2","a":"sss","b":"sss","question":"whi?"},
{"id":"3","a":"sss","b":"sss","question":"whi?"},
{"id":"4","a":"sss","b":"sss","question":"whi?"}]};

ShareInfoLength = data.shareInfo.length;
alert(ShareInfoLength);
for(var i=0; i<ShareInfoLength; i++)
{
alert(Object.keys(data.shareInfo[i]).length);
}

Use indexOf

imageList.indexOf(200)

The AngularJS documentation on directives is pretty well written for what the symbols mean.

To be clear, you cannot just have

scope: '@'

in a directive definition. You must have properties for which those bindings apply, as in:

scope: {
    myProperty: '@'
}

I strongly suggest you read the documentation and the tutorials on the site. There is much more information you need to know about isolated scopes and other topics.

Here is a direct quote from the above-linked page, regarding the values of scope:

The scope property can be true, an object or a falsy value:

• falsy: No scope will be created for the directive. The directive will use its parent's scope.

• true: A new child scope that prototypically inherits from its parent will be created for the directive's element. If multiple directives on the same element request a new scope, only one new scope is created. The new scope rule does not apply for the root of the template since the root of the template always gets a new scope.

• {...} (an object hash): A new "isolate" scope is created for the directive's element. The 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent scope. This is useful when creating reusable components, which should not accidentally read or modify data in the parent scope.

(Three years late...) but I believe the answer to your second question is that SSRS essentially treats data from your datasets as unsorted; I'm not sure if it ignores any ORDER BY in the sql, or if it just assumes the data is unsorted.

To sort your groups in a particular order, you need to specify it in the report:

• Select the chart,
• In the Chart Data popup window (where you specify the Category Groups), right-click your Group and click Category Group Properties,
• Click on the Sorting option to see a control to set the Sort order

For the report I just created, the default sort order on the category was alphabetic on the category group which was basically a string code. But sometimes it can be useful to sort by some other characteristic of the data; for example, my report is of Average and Maximum processing times for messages identified by some code (the category). By setting the sort order of the group to be on [MaxElapsedMs], Z->A it draws my attention to the worst-performing message-types.

This sort of presentation won't be useful for every report but it can be an excellent tool to guide readers to have a better understanding of the data; though on other occasions you might prefer a report to have the same ordering every time it runs, in which case sorting on the category label itself may be best... and I guess there are circumstances where changing the sort order could harm understanding, such as if the categories implied some sort of ordering (such as date values?)

Open Office / LibreOffice based solutions will do an OK job, but don't expect your PDFs to resemble your source files if they were created in MS-Office. A PDF that looks 90% like the original is not considered to be acceptable in many fields.

The only way to make sure your PDFs look exactly like the originals is to use a solution that uses the official MS-Office DLLs under the hood. If you are running your PHP solution on non-Windows based servers then it requires an additional Windows Server. This may be a showstopper, but if you really care about the look and feel of your PDFs you may not have an option.

Have a look at this blog post. It shows how to use PHP to convert MS-Office files with a high level of fidelity.

Disclaimer: I wrote this blog post and worked on a related commercial product, so consider me biased. However, it appears to be a great solution for the PHP people I work with.

__main__.py is used for python programs in zip files. The __main__.py file will be executed when the zip file in run. For example, if the zip file was as such:

test.zip
     __main__.py

and the contents of __main__.py was

import sys
print "hello %s" % sys.argv[1]

Then if we were to run python test.zip world we would get hello world out.

So the __main__.py file run when python is called on a zip file.

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

Yes, but be careful when using between for dates.

BETWEEN '20090101' AND '20090131'

is really interpreted as 12am, or

BETWEEN '20090101 00:00:00' AND '20090131 00:00:00'

so will miss anything that occurred during the day of Jan 31st. In this case, you will have to use:

myDate >= '20090101 00:00:00' AND myDate < '20090201 00:00:00'  --CORRECT!

or

BETWEEN '20090101 00:00:00' AND '20090131 23:59:59' --WRONG! (see update!)

UPDATE: It is entirely possible to have records created within that last second of the day, with a datetime as late as 20090101 23:59:59.997!!

For this reason, the BETWEEN (firstday) AND (lastday 23:59:59) approach is not recommended.

Use the myDate >= (firstday) AND myDate < (Lastday+1) approach instead.

Good article on this issue here.

Have not tested it yet, but the looks are better than the one Alex mentions.

The description at winginx.com/en/htaccess says:

About the htaccess to nginx converter

The service is to convert an Apache's .htaccess to nginx configuration instructions.

First of all, the service was thought as a mod_rewrite to nginx converter. However, it allows you to convert some other instructions that have reason to be ported from Apache to nginx.

Note server instructions (e.g. php_value, etc.) are ignored.

The converter does not check syntax, including regular expressions and logic errors.

Please, check the result manually before use.

Several third-party libraries have classes encapsulating the concept of a range, such as Apache commons-lang's Range (and subclasses).

Using classes such as this you could express your constraint similar to:

if (new IntRange(0, 5).contains(orderBean.getFiles().size())
// (though actually Apache's Range is INclusive, so it'd be new Range(1, 4) - meh

with the added bonus that the range object could be defined as a constant value elsewhere in the class.

However, without pulling in other libraries and using their classes, Java's strong syntax means you can't massage the language itself to provide this feature nicely. And (in my own opinion), pulling in a third party library just for this small amount of syntactic sugar isn't worth it.

The extend method for example in jQuery or PrototypeJS, copies all properties from the source to the destination object.

Now about the prototype property, it is a member of function objects, it is part of the language core.

Any function can be used as a constructor, to create new object instances. All functions have this prototype property.

When you use the new operator with on a function object, a new object will be created, and it will inherit from its constructor prototype.

For example:

function Foo () {
}
Foo.prototype.bar = true;

var foo = new Foo();

foo.bar; // true
foo instanceof Foo; // true
Foo.prototype.isPrototypeOf(foo); // true

There is no such thing built-in, since R does not track calls to source and is not able to figure out what was loaded from where (this is not the case when using packages). Yet, you may use same idea as in C .h files, i.e. wrap the whole in:

if(!exists('util_R')){
 util_R<-T

 #Code

}

CREATE OR REPLACE PROCEDURE ADDEMP
    (xml IN CLOB)

END;

No macros required. Data as below, two columns, dates don't need to be in order. Select range, convert to a Table (Ctrl+T). When data is added to the table, a chart based on the table will automatically include the added data.

Select table, insert a line chart. Right click chart, choose Select Data, click on Blank and Hidden Cells button, choose Interpolate option.

Usually a simple hash function works by taking the "component parts" of the input (characters in the case of a string), and multiplying them by the powers of some constant, and adding them together in some integer type. So for example a typical (although not especially good) hash of a string might be:

(first char) + k * (second char) + k^2 * (third char) + ...

Then if a bunch of strings all having the same first char are fed in, then the results will all be the same modulo k, at least until the integer type overflows.

[As an example, Java's string hashCode is eerily similar to this - it does the characters reverse order, with k=31. So you get striking relationships modulo 31 between strings that end the same way, and striking relationships modulo 2^32 between strings that are the same except near the end. This doesn't seriously mess up hashtable behaviour.]

A hashtable works by taking the modulus of the hash over the number of buckets.

It's important in a hashtable not to produce collisions for likely cases, since collisions reduce the efficiency of the hashtable.

Now, suppose someone puts a whole bunch of values into a hashtable that have some relationship between the items, like all having the same first character. This is a fairly predictable usage pattern, I'd say, so we don't want it to produce too many collisions.

It turns out that "because of the nature of maths", if the constant used in the hash, and the number of buckets, are coprime, then collisions are minimised in some common cases. If they are not coprime, then there are some fairly simple relationships between inputs for which collisions are not minimised. All the hashes come out equal modulo the common factor, which means they'll all fall into the 1/n th of the buckets which have that value modulo the common factor. You get n times as many collisions, where n is the common factor. Since n is at least 2, I'd say it's unacceptable for a fairly simple use case to generate at least twice as many collisions as normal. If some user is going to break our distribution into buckets, we want it to be a freak accident, not some simple predictable usage.

Now, hashtable implementations obviously have no control over the items put into them. They can't prevent them being related. So the thing to do is to ensure that the constant and the bucket counts are coprime. That way you aren't relying on the "last" component alone to determine the modulus of the bucket with respect to some small common factor. As far as I know they don't have to be prime to achieve this, just coprime.

But if the hash function and the hashtable are written independently, then the hashtable doesn't know how the hash function works. It might be using a constant with small factors. If you're lucky it might work completely differently and be nonlinear. If the hash is good enough, then any bucket count is just fine. But a paranoid hashtable can't assume a good hash function, so should use a prime number of buckets. Similarly a paranoid hash function should use a largeish prime constant, to reduce the chance that someone uses a number of buckets which happens to have a common factor with the constant.

In practice, I think it's fairly normal to use a power of 2 as the number of buckets. This is convenient and saves having to search around or pre-select a prime number of the right magnitude. So you rely on the hash function not to use even multipliers, which is generally a safe assumption. But you can still get occasional bad hashing behaviours based on hash functions like the one above, and prime bucket count could help further.

Putting about the principle that "everything has to be prime" is as far as I know a sufficient but not a necessary condition for good distribution over hashtables. It allows everybody to interoperate without needing to assume that the others have followed the same rule.

[Edit: there's another, more specialized reason to use a prime number of buckets, which is if you handle collisions with linear probing. Then you calculate a stride from the hashcode, and if that stride comes out to be a factor of the bucket count then you can only do (bucket_count / stride) probes before you're back where you started. The case you most want to avoid is stride = 0, of course, which must be special-cased, but to avoid also special-casing bucket_count / stride equal to a small integer, you can just make the bucket_count prime and not care what the stride is provided it isn't 0.]

@Marton had an important objection to the accepted answer on the grounds that the pipe creates a new collection on each change detection. I would instead create an HtmlService which provides a range of utility functions which the view can use as follows:

@Component({
  selector: 'app-myview',
  template: `<div *ngFor="let i of html.keys(items)">{{i + ' : ' + items[i]}}</div>`
})
export class MyComponent {
  items = {keyOne: 'value 1', keyTwo: 'value 2', keyThree: 'value 3'};
  constructor(private html: HtmlService){}
}

@Injectable()
export class HtmlService {
  keys(object: {}) {
    return Object.keys(object);
  }
  // ... other useful methods not available inside html, like isObject(), isArray(), findInArray(), and others...
}

For React 16 and React >=15.6

Setter .value= is not working as we wanted because React library overrides input value setter but we can call the function directly on the input as context.

var nativeInputValueSetter = Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, "value").set;
nativeInputValueSetter.call(input, 'react 16 value');

var ev2 = new Event('input', { bubbles: true});
input.dispatchEvent(ev2);

For textarea element you should use prototype of HTMLTextAreaElement class.

New codepen example.

Outdated answer only for React <=15.5

With react-dom ^15.6.0 you can use simulated flag on the event object for the event to pass through

var ev = new Event('input', { bubbles: true});
ev.simulated = true;
element.value = 'Something new';
element.dispatchEvent(ev);

I made a codepen with an example

To understand why new flag is needed I found this comment very helpful:

The input logic in React now dedupe's change events so they don't fire more than once per value. It listens for both browser onChange/onInput events as well as sets on the DOM node value prop (when you update the value via javascript). This has the side effect of meaning that if you update the input's value manually input.value = 'foo' then dispatch a ChangeEvent with { target: input } React will register both the set and the event, see it's value is still `'foo', consider it a duplicate event and swallow it.

This works fine in normal cases because a "real" browser initiated event doesn't trigger sets on the element.value. You can bail out of this logic secretly by tagging the event you trigger with a simulated flag and react will always fire the event. https://github.com/jquense/react/blob/9a93af4411a8e880bbc05392ccf2b195c97502d1/src/renderers/dom/client/eventPlugins/ChangeEventPlugin.js#L128

Adding to @HYRY's answer in1d seems to be fastest for numpy. This is using numpy 1.8 and python 2.7.6.

In this test in1d was fastest, however 10 in a look cleaner:

a = arange(0,99999,3)
%timeit 10 in a
%timeit in1d(a, 10)

10000 loops, best of 3: 150 µs per loop
10000 loops, best of 3: 61.9 µs per loop

Constructing a set is slower than calling in1d, but checking if the value exists is a bit faster:

s = set(range(0, 99999, 3))
%timeit 10 in s

10000000 loops, best of 3: 47 ns per loop

The format is %lu.

Please check about the various other datatypes and their usage in printf here

If you decide to use ggplot2, you can set transparency of overlapping points using the alpha argument.

e.g.

library(ggplot2)
ggplot(diamonds, aes(carat, price)) + geom_point(alpha = 1/40)

For what it's worth, I needed to update the port and scheme for SSL for my RESTFul service. This is what I did. Apologies that it is a bit more that the original question, but hopefully useful to someone.

// Don't forget to add references to System.ServiceModel and System.ServiceModel.Web

using System.ServiceModel;
using System.ServiceModel.Configuration;

var port = 1234;
var isSsl = true;
var scheme = isSsl ? "https" : "http";

var currAssembly = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
Configuration config = ConfigurationManager.OpenExeConfiguration(currAssembly);

ServiceModelSectionGroup serviceModel = ServiceModelSectionGroup.GetSectionGroup(config);

// Get the first endpoint in services.  This is my RESTful service.
var endp = serviceModel.Services.Services[0].Endpoints[0];

// Assign new values for endpoint
UriBuilder b = new UriBuilder(endp.Address);
b.Port = port;
b.Scheme = scheme;
endp.Address = b.Uri;

// Adjust design time baseaddress endpoint
var baseAddress = serviceModel.Services.Services[0].Host.BaseAddresses[0].BaseAddress;
b = new UriBuilder(baseAddress);
b.Port = port;
b.Scheme = scheme;
serviceModel.Services.Services[0].Host.BaseAddresses[0].BaseAddress = b.Uri.ToString();

// Setup the Transport security
BindingsSection bindings = serviceModel.Bindings;
WebHttpBindingCollectionElement x =(WebHttpBindingCollectionElement)bindings["webHttpBinding"];
WebHttpBindingElement y = (WebHttpBindingElement)x.ConfiguredBindings[0];
var e = y.Security;

e.Mode = isSsl ? WebHttpSecurityMode.Transport : WebHttpSecurityMode.None;
e.Transport.ClientCredentialType = HttpClientCredentialType.None;

// Save changes
config.Save();

use

location.reload();

or

window.location.reload();

Long ago, when all we had was sh, Booleans where handled by relying on a convention of the test program where test returns a false exit status if run without any arguments.

This allows one to think of a variable that is unset as false and variable set to any value as true. Today, test is a builtin to Bash and is commonly known by its one-character alias [ (or an executable to use in shells lacking it, as dolmen notes):

FLAG="up or <set>"

if [ "$FLAG" ] ; then
    echo 'Is true'
else
    echo 'Is false'
fi

# Unset FLAG
#    also works
FLAG=

if [ "$FLAG" ] ; then
    echo 'Continues true'
else
    echo 'Turned false'
fi

Because of quoting conventions, script writers prefer to use the compound command [[ that mimics test, but has a nicer syntax: variables with spaces do not need to be quoted; one can use && and || as logical operators with weird precedence, and there are no POSIX limitations on the number of terms.

For example, to determine if FLAG is set and COUNT is a number greater than 1:

FLAG="u p"
COUNT=3

if [[ $FLAG  && $COUNT -gt '1' ]] ; then
    echo 'Flag up, count bigger than 1'
else
    echo 'Nope'
fi

This stuff can get confusing when spaces, zero length strings, and null variables are all needed and also when your script needs to work with several shells.

A useful 2D vector operation is a cross product that returns a scalar. I use it to see if two successive edges in a polygon bend left or right.

From the Chipmunk2D source:

/// 2D vector cross product analog.
/// The cross product of 2D vectors results in a 3D vector with only a z component.
/// This function returns the magnitude of the z value.
static inline cpFloat cpvcross(const cpVect v1, const cpVect v2)
{
        return v1.x*v2.y - v1.y*v2.x;
}

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

$("input").click(function() {_x000D_
  var bd = $('<div class="modal-backdrop"></div>');_x000D_
  bd.appendTo(document.body);_x000D_
  setTimeout(function() {_x000D_
    bd.remove();_x000D_
  }, 2000);_x000D_
});

Whether this answer is universally true or not, I don't know, but I solved this by altering my query slightly.

Rather than joining a select query to a table and processing it, I changed the select query to create a temporary table. I then used that temporary table to the real table and it all worked perfectly.

Wow, this had me tearing my hair out, banging my head against walls, tables and other things. I had the same or a similar issue as the OP where it was either missing / not downloading the jar files or downloading them, but not including them in the Maven dependencies with the same error message. My limited knowledge of java packaging and maven probably didn't help.

For me the problem seems to have been caused by the Dependency Type "bundle" (but I don't know how or why). I was using the Add Dependency dialog in Eclipse Mars on the pom.xml, which allows you to search and browse the central repository. I was searching and adding a dependency to jackson-core libraries, picking the latest version, available as a bundle. This kept failing.

So finally, I changed the dependency properties form bundle to jar (again using the dependency properties window), which finally downloaded and referenced the dependencies properly after saving the changes.

I had to edit the C:\Windows\System32\inetsrv\config\applicationHost.config file and add <requestLimits maxAllowedContentLength="1073741824" /> to the end of the...

<configuration>
    <system.webServer>

            <requestFiltering>

section.

Complementing Matt Frear's answer - This would be an ASP NET Core alternative for reading the file directly from Stream, without saving&reading it from disk:

public ActionResult OnPostUpload(List<IFormFile> files)
    {
        try
        {
            var file = files.FirstOrDefault();
            var inputstream = file.OpenReadStream();

            XSSFWorkbook workbook = new XSSFWorkbook(stream);

            var FIRST_ROW_NUMBER = {{firstRowWithValue}};

            ISheet sheet = workbook.GetSheetAt(0);
            // Example: var firstCellRow = (int)sheet.GetRow(0).GetCell(0).NumericCellValue;

            for (int rowIdx = 2; rowIdx <= sheet.LastRowNum; rowIdx++)
               {
                  IRow currentRow = sheet.GetRow(rowIdx);

                  if (currentRow == null || currentRow.Cells == null || currentRow.Cells.Count() < FIRST_ROW_NUMBER) break;

                  var df = new DataFormatter();                

                  for (int cellNumber = {{firstCellWithValue}}; cellNumber < {{lastCellWithValue}}; cellNumber++)
                      {
                         //business logic & saving data to DB                        
                      }               
                }
        }
        catch(Exception ex)
        {
            throw new FileFormatException($"Error on file processing - {ex.Message}");
        }
    }

I think you are looking for this function:

http://doc.qt.io/qt-5/qdatetime.html#toTime_t

uint QDateTime::toTime_t () const

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).

On systems that do not support time zones, this function will behave as if local time were Qt::UTC.

See also setTime_t().

You can exchange this local variable for a global, it would be easier.

DROP PROCEDURE IF EXISTS ABC;
DELIMITER $$  
CREATE PROCEDURE ABC()

   BEGIN
      SET @a = 0;
      simple_loop: LOOP
         SET @a=@a+1;
         select @a;
         IF @a=5 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

You'll need to add this to your server configuration:

AddType application/x-httpd-php .php

That is assuming you have installed PHP properly, which may not be the case since it doesn't work where it normally would immediately after installing.

It is entirely possible that you'll also have to add the php .so/.dll file to your Apache configuration using a LoadModule directive (usually in httpd.conf).

For visual learners, when defining the function without .prototype

ExampleClass = function(){};
ExampleClass.method = function(customString){
             console.log((customString !== undefined)? 
                          customString : 
                          "called from func def.");}
ExampleClass.method(); // >> output: `called from func def.`  

var someInstance = new ExampleClass();
someInstance.method('Called from instance');
    // >> error! `someInstance.method is not a function`  

With same code, if .prototype is added,

ExampleClass.prototype.method = function(customString){
             console.log((customString !== undefined)? 
                          customString : 
                          "called from func def.");}
ExampleClass.method();  
      // > error! `ExampleClass.method is not a function.`  

var someInstance = new ExampleClass();
someInstance.method('Called from instance');
                 // > output: `Called from instance`

To make it clearer,

ExampleClass = function(){};
ExampleClass.directM = function(){}  //M for method
ExampleClass.prototype.protoM = function(){}

var instanceOfExample = new ExampleClass();

ExampleClass.directM();     ? works
instanceOfExample.directM();   x Error!

ExampleClass.protoM();     x Error!
instanceOfExample.protoM();  ? works

****Note for the example above, someInstance.method() won't be executed as,
ExampleClass.method() causes error & execution cannot continue.
But for the sake of illustration & easy understanding, I've kept this sequence.****

Write it as a one-liner:

figure('position', [0, 0, 200, 500])  % create new figure with specified size  

If you have a table called memos that has two columns id and text you should be able to do like this:

INSERT INTO memos(id,text) 
SELECT 5, 'text to insert' 
WHERE NOT EXISTS(SELECT 1 FROM memos WHERE id = 5 AND text = 'text to insert');

If a record already contains a row where text is equal to 'text to insert' and id is equal to 5, then the insert operation will be ignored.

I don't know if this will work for your particular query, but perhaps it give you a hint on how to proceed.

I would advice that you instead design your table so that no duplicates are allowed as explained in @CLs answer below.

Sending XHR requests is bad because it could fail if that particular server is down. Instead, use googles API library to load their cached version(s) of jQuery.

You can use googles API to perform a callback after loading jQuery, and this will check if jQuery was loaded successfully. Something like the code below should work:

<script type="text/javascript">
    google.load("jquery");

    // Call this function when the page has been loaded
    function test_connection() {
        if($){
            //jQuery WAS loaded.
        } else {
            //jQuery failed to load.  Grab the local copy.
        }
    }
    google.setOnLoadCallback(test_connection);
</script>

The google API documentation can be found here.

This is one of the ways:

String toDate = "05/11/2010";

if (new SimpleDateFormat("MM/dd/yyyy").parse(toDate).getTime() / (1000 * 60 * 60 * 24) >= System.currentTimeMillis() / (1000 * 60 * 60 * 24)) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

A bit more easy interpretable:

String toDateAsString = "05/11/2010";
Date toDate = new SimpleDateFormat("MM/dd/yyyy").parse(toDateAsString);
long toDateAsTimestamp = toDate.getTime();
long currentTimestamp = System.currentTimeMillis();
long getRidOfTime = 1000 * 60 * 60 * 24;
long toDateAsTimestampWithoutTime = toDateAsTimestamp / getRidOfTime;
long currentTimestampWithoutTime = currentTimestamp / getRidOfTime;

if (toDateAsTimestampWithoutTime >= currentTimestampWithoutTime) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Oh, as a bonus, the JodaTime's variant:

String toDateAsString = "05/11/2010";
DateTime toDate = DateTimeFormat.forPattern("MM/dd/yyyy").parseDateTime(toDateAsString);
DateTime now = new DateTime();

if (!toDate.toLocalDate().isBefore(now.toLocalDate())) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Building on the suggestion of using drawImage you could also combine this with scale function.

So before you draw the image scale the context to the zoom level you want:

ctx.scale(2, 2) // Doubles size of anything draw to canvas.

I've created a small example here http://jsfiddle.net/mBzVR/4/ that uses drawImage and scale to zoom in on mousedown and out on mouseup.

Use numpy.apply_along_axis(). Assuming your matrix is 2D, you can use like:

import numpy as np
mymatrix = np.matrix([[11,12,13],
                      [21,22,23],
                      [31,32,33]])
def myfunction( x ):
    return sum(x)

print np.apply_along_axis( myfunction, axis=1, arr=mymatrix )
#[36 66 96]

    NSDateFormatter *dateformat = [[NSDateFormatter alloc] init];
    [dateformat setDateFormat:@"Your Date Format"];

set the format to return is....

yyyy-MM-dd return 2015-12-17 date

yyyy-MMM-dd return 2015-Dec-17 date

yy-MM-dd return 15-12-17 date

dd-MM-yy return 17-12-15 date

dd-MM-yyyy return 17-12-2015 date

yyyy-MMM-dd HH:mm:ss return 2015-Dec-17 08:07:13 date and time

yyyy-MMM-dd HH:mm return 2015-Dec-17 08:07 date and time

origin is an alias on your system for a particular remote repository. It's not actually a property of that repository.

By doing

git push origin branchname

you're saying to push to the origin repository. There's no requirement to name the remote repository origin: in fact the same repository could have a different alias for another developer.

Remotes are simply an alias that store the URL of repositories. You can see what URL belongs to each remote by using

git remote -v

In the push command, you can use remotes or you can simply use a URL directly. An example that uses the URL:

git push [email protected]:git/git.git master

You use the error_page property in the nginx config.

For example, if you intend to set the 404 error page to /404.html, use

error_page 404 /404.html;

Setting the 500 error page to /500.html is just as easy as:

error_page 500 /500.html;

In clean Ubuntu 16.04 LTS, MariaDB root login for localhost changed from password style to sudo login style...

so, just do

sudo mysql -u root

since we want to login with password, create another user 'user'

in MariaDB console... (you get in MariaDB console with 'sudo mysql -u root')

use mysql
CREATE USER 'user'@'localhost' IDENTIFIED BY 'yourpassword';
\q

then in bash shell prompt,

mysql-workbench

and you can login with 'user' with 'yourpassword' on localhost

You can use Container to contain your widget:

Container(
  decoration: BoxDecoration(
    border: Border.all(
    color: Color(0xff000000),
    width: 1,
  )),
  child: Text()
),

Super late here and I still couldn't uninstall using sudo as the other answers suggest. What did it for me was checking where cordova was installed by running

which cordova

it will output something like this

/usr/local/bin/

then removing by

rm -rf /usr/local/bin/cordova

Looks like no, though it was requested, and there’s a UDF for it.

Edit: Or there’s… this. Ugh.

%d prints an integer: it will print the ascii representation of your character. What you need is %c:

printf("%c", ch);

printf("%d", '\0'); prints the ascii representation of '\0', which is 0 (by escaping 0 you tell the compiler to use the ascii value 0.

printf("%d", sizeof('\n')); prints 4 because a character literal is an int, in C, and not a char.
