This is how I did it, in my code

 ...
 global $wpdb;
 $query =  "INSERT INTO... VALUES(...)" ;
 $wpdb->query(
        $wpdb->prepare($query)
);
return $wpdb->insert_id;
...

More Class Variables

You can prevent race condition, if you use "Atomic" classes. The reason is just the thread don't separate operation get and set, example is below:

AtomicInteger ai = new AtomicInteger(2);
ai.getAndAdd(5);

As a result, you will have 7 in link "ai". Although you did two actions, but the both operation confirm the same thread and no one other thread will interfere to this, that means no race conditions!

This should be the answer you are looking for

EmployeeInfo.objects.update_or_create(
    #id or any primary key:value to search for
    identifier=your_id, 
    #if found update with the following or save/create if not found
    defaults={'name':'your_name'}
)

This works for me:

$entities = $em->getRepository('MyBundle:MyTable')->findBy(array(),array('name' => 'ASC'));

Keeping the first array empty fetches back all data, it worked in my case.

[ES6] This code works for me.

let result = array.map(item => item.id === updatedItem.id ? updatedItem : item)

I struggled with this from behind a proxy so I thought I should post what I did. Below one is worked for me.

-> "export HTTPS_PROXY=(yourproxy)"

This is a crazy thing of apple. When you say self.navigationItem.rightBarButtonItem.title then it will say nil while on the GUI it shows Edit or Save. Fresher likes me will take a lot of time to debug this behavior.

There is a requirement that the Item will show Edit in the firt load then user taps on it It will change to Save title. To archive this, i did as below.

//view did load will say Edit title

private func loadRightBarItem() {
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
}

// tap Edit item will change to Save title

@objc private func handleEditBtn() {
    print("clicked on Edit btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Save", style: .done, target: self, action: #selector(handleSaveBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
    blockEditTable(isBlock: false)
}

//tap Save item will display Edit title

@objc private func handleSaveBtn(){
    print("clicked on Save btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem

    saveInvitation()
    blockEditTable(isBlock: true)

}

You should not be operating the state at all. At least, not directly. If you want to update your array, you'll want to do something like this.

var newStateArray = this.state.myArray.slice();
newStateArray.push('new value');
this.setState(myArray: newStateArray);

Working on the state object directly is not desirable. You can also take a look at React's immutability helpers.

Both are valid. It's your choice.

I prefer border:0 because it's shorter; I find that easier to read. You may find none more legible. We live in a world of very capable CSS post-processors so I'd recommend you use whatever you prefer and then run it through a "compressor". There's no holy war worth fighting here but Webpack?LESS?PostCSS?PurgeCSS is a good 2020 stack.

That all said, if you're hand-writing all your production CSS, I maintain —despite the grumbling in the comments— it does not hurt to be bandwidth conscious. Using border:0 will save an infinitesimal amount of bandwidth on its own, but if you make every byte count, you will make your website faster.

The CSS2 specs are here. These are extended in CSS3 but not in any way relevant to this.

'border'
    Value:      [ <border-width> || <border-style> || <'border-top-color'> ] | inherit
    Initial:    see individual properties
    Applies to:     all elements
    Inherited:      no
    Percentages:    N/A
    Media:      visual
    Computed value:     see individual properties 

You can use any combination of width, style and colour.
Here, 0 sets the width, none the style. They have the same rendering result: nothing is shown.

You should join T1 and T2 tables using sql joins in order to analyze from two tables. Link for learn joins : https://www.w3schools.com/sql/sql_join.asp

If I understand your question right you are asking what is difference if you register listener callback with $watch or if you do it with $observe.

Callback registerd with $watch is fired when $digest is executed.

Callback registered with $observe are called when value changes of attributes that contain interpolation (e.g. attr="{{notJetInterpolated}}").

Inside directive you can use both of them on very similar way:

    attrs.$observe('attrYouWatch', function() {
         // body
    });

or

    scope.$watch(attrs['attrYouWatch'], function() {
         // body
    });

If you want to look in all tables in all Databases server-wide and get output you can make use of the undocumented sp_MSforeachdb procedure:

sp_MSforeachdb 'SELECT "?" AS DB, * FROM [?].sys.tables WHERE name like ''%Table_Names%'''

In which scenarios does one out-perform the other?

For smaller tables (less than 1000 rows) use a temp variable, otherwise use a temp table.

Never use =='NA' to test for missing values. Use is.na() instead. This should do it:

new_DF <- DF[rowSums(is.na(DF)) > 0,]

or in case you want to check a particular column, you can also use

new_DF <- DF[is.na(DF$Var),]

In case you have NA character values, first run

Df[Df=='NA'] <- NA

to replace them with missing values.

This error might also pop-up if you run the rsync process for files that are not recently modified in the source or destination...because it cant set the time for the recently modified files.

WebClient doesn't have a direct support for form data, but you can send a HTTP post by using the UploadString method:

Using client as new WebClient
    result = client.UploadString(someurl, "param1=somevalue&param2=othervalue")
End Using

Similar and thanks to tslegaitis's answer, after

gcloud builds submit --config cloudbuild.yaml . 

it shows

Check the gcloud log [/home/USER/.config/gcloud/logs/2020.05.24/21.12.04.NUMBERS.log] to see which files and the contents of the
default gcloudignore file used (see `$ gcloud topic gcloudignore` to learn
more).

Checking that log, it says that docker will use .gitignore:

DATE Using default gcloudignore file:
# This file specifies files that are *not* uploaded to Google Cloud Platform
# using gcloud. It follows the same syntax as .gitignore, with the addition of
# "#!include" directives (which insert the entries of the given .gitignore-style
# file at that point).
# ...

.gitignore

So I fixed my .gitignore (I use it as whitelist instead) and docker copied the file.

[I added the answer because I have not enough reputation to comment]

In one controller, you can do:

$rootScope.$broadcast('eventName', data);

and listen to the event in another:

$scope.$on('eventName', function (event, data) {...});

var test = {'red':'#FF0000', 'blue':'#0000FF'};_x000D_
delete test.blue; // or use => delete test['blue'];_x000D_
console.log(test);

this deletes test.blue

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

In confing.yml

# app/config/config.yml
twig:
  globals:
    version: '%app.version%'

In Twig view

# twig view
{{ version }}

Another method through re module. It does the reverse operation of matching all the words instead of spitting the whole sentence by space.

>>> import re
>>> s = "many   fancy word \nhello    \thi"
>>> re.findall(r'\S+', s)
['many', 'fancy', 'word', 'hello', 'hi']

Above regex would match one or more non-space characters.

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");

Result:

"Hello, this is Mike"

Real mirror:

.mirror{_x000D_
    display: inline-block; _x000D_
    font-size: 30px;_x000D_
_x000D_
    -webkit-transform: matrix(-1, 0, 0, 1, 0, 0);_x000D_
    -moz-transform: matrix(-1, 0, 0, 1, 0, 0);_x000D_
    -o-transform: matrix(-1, 0, 0, 1, 0, 0);_x000D_
    transform: matrix(-1, 0, 0, 1, 0, 0);_x000D_
}

<span class='mirror'>Mirror Text<span>

Within the class you can call function by using :

 $this->filter();

Outside of the class

you have to create an object of a class

 ex: $obj = new Functions();

     $obj->filter($param);    

for more about OOPs in php

this example:

class test {
 public function newTest(){
      $this->bigTest();// we don't need to create an object we can call simply using $this
      $this->smallTest();
 }

 private function bigTest(){
      //Big Test Here
 }

 private function smallTest(){
      //Small Test Here
 }

 public function scoreTest(){
      //Scoring code here;
 }
}

$testObject = new test();

$testObject->newTest();

$testObject->scoreTest();

hope it will help!

You should try this one.

var table = $('#example').DataTable();
table.columns.adjust().draw();

Or command line Python, for example, for 6 and a half seconds:

python -c "import time;time.sleep(6.5)"

Hi me also faced same issue , solved using below steps:

cause 1:

Add internet permission in your android application

cause 2:

Check the manually your default application is able access internet or not if not its problem of your emulator , check in your internet connection in your pc

try below method to connect net in your pc

try explicitly specifying DNS server settings, this worked for me.

In Eclipse:

Window>Preferences>Android>Launch

Default emulator options: -dns-server 8.8.8.8,8.8.4.4**

cause 3:

check : check if you are using more than one internet connection to your pc like one is LAN second one is Modem , so disable all lan or modem .

For Jersey 2 you'd need to modify the code:

        return ClientBuilder.newBuilder()
            .withConfig(config)
            .hostnameVerifier(new TrustAllHostNameVerifier())
            .sslContext(ctx)
            .build();

Long time since I've done Assembly programming, but this link might be useful...

The processor has a collection of registers which are used to store data. Some of these are direct values while others are pointing to an area within RAM. Registers do tend to be used for certain specific actions and every operand in assembly will require a certain amount of data in specific registers.

The stack pointer is mostly used when you're calling other procedures. With modern compilers, a bunch of data will be dumped first on the stack, followed by the return address so the system will know where to return once it's told to return. The stack pointer will point at the next location where new data can be pushed to the stack, where it will stay until it's popped back again.

Base registers or segment registers just point to the address space of a large amount of data. Combined with a second regiser, the Base pointer will divide the memory in huge blocks while the second register will point at an item within this block. Base pointers therefor point to the base of blocks of data.

Do keep in mind that Assembly is very CPU specific. The page I've linked to provides information about different types of CPU's.

Yes, you can. Return an Action like this :

return RedirectToAction("View", "Name of Controller");

An example:

return RedirectToAction("Details/" + id.ToString(), "FullTimeEmployees");

This approach will call the GET method

Also you could pass values to action like this:

return RedirectToAction("Details/" + id.ToString(), "FullTimeEmployees", new {id = id.ToString(), viewtype = "extended" });

Update:

Read the Docs for your version of Django. e.g.

https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/3.0/ref/contrib/admin/#admin-overriding-templates

Original answer from 2011:

I had the same issue about a year and a half ago and I found a nice template loader on djangosnippets.org that makes this easy. It allows you to extend a template in a specific app, giving you the ability to create your own admin/index.html that extends the admin/index.html template from the admin app. Like this:

{% extends "admin:admin/index.html" %}

{% block sidebar %}
    {{block.super}}
    <div>
        <h1>Extra links</h1>
        <a href="/admin/extra/">My extra link</a>
    </div>
{% endblock %}

I've given a full example on how to use this template loader in a blog post on my website.

Don't do anything in Parent ScrollView. Only do this to child ListView. Everything will work perfectly.

mListView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                mScrollView.requestDisallowInterceptTouchEvent(true);
               int action = event.getActionMasked();
                switch (action) {
                    case MotionEvent.ACTION_UP:
                        mScrollView.requestDisallowInterceptTouchEvent(false);
                        break;
                }
                return false;
            }
        });

If the return in the try block is reached, it transfers control to the finally block, and the function eventually returns normally (not a throw).

If an exception occurs, but then the code reaches a return from the catch block, control is transferred to the finally block and the function eventually returns normally (not a throw).

In your example, you have a return in the finally, and so regardless of what happens, the function will return 34, because finally has the final (if you will) word.

Although not covered in your example, this would be true even if you didn't have the catch and if an exception were thrown in the try block and not caught. By doing a return from the finally block, you suppress the exception entirely. Consider:

public class FinallyReturn {
  public static final void main(String[] args) {
    System.out.println(foo(args));
  }

  private static int foo(String[] args) {
    try {
      int n = Integer.parseInt(args[0]);
      return n;
    }
    finally {
      return 42;
    }
  }
}

If you run that without supplying any arguments:

$ java FinallyReturn

...the code in foo throws an ArrayIndexOutOfBoundsException. But because the finally block does a return, that exception gets suppressed.

This is one reason why it's best to avoid using return in finally.

Get the EOF position of the file:

def get_eof_position(file_handle):
    original_position = file_handle.tell()
    eof_position = file_handle.seek(0, 2)
    file_handle.seek(original_position)
    return eof_position

and compare it with the current position: get_eof_position == file_handle.tell().

I am a little bit surprised nobody mentioned

sp_help 'mytable'

$ git checkout stash@{0} -- <filename>

Notes:

1. Make sure you put space after the "--" and the file name parameter

2. Replace zero(0) with your specific stash number. To get stash list, use:

   git stash list
   

Based on Jakub Narebski's answer -- Shorter version

I know the question is asking about your "csv" package implementation, but for your information, there are options that are much simpler — numpy, for instance.

import numpy as np
np.savetxt('data.csv', (col1_array, col2_array, col3_array), delimiter=',')

(This answer posted 6 years later, for posterity's sake.)

In a different case similar to what you're asking about, say you have two columns like this:

names = ['Player Name', 'Foo', 'Bar']
scores = ['Score', 250, 500]

You could save it like this:

np.savetxt('scores.csv', [p for p in zip(names, scores)], delimiter=',', fmt='%s')

scores.csv would look like this:

Player Name,Score
Foo,250
Bar,500

This code works with integer lists in a recursive way. Looks for the simplest case scenario, which is: list length less than 2. It means the answer is already there and a test is performed to check for the correct answer. If not, a middle value is set and tested to be the correct, if not bisection is performed by calling again the function, but setting middle value as the upper or lower limit, by shifting it to the left or right

def binary_search(intList, intValue, lowValue, highValue):
    if(highValue - lowValue) < 2:
        return intList[lowValue] == intValue or intList[highValue] == intValue
    middleValue = lowValue + ((highValue - lowValue)/2)
    if intList[middleValue] == intValue:
        return True
    if intList[middleValue] > intValue:
        return binary_search(intList, intValue, lowValue, middleValue - 1)
   return binary_search(intList, intValue, middleValue + 1, highValue)

Use this batch file: RunWithQt.bat

set QT_QPA_PLATFORM_PLUGIN_PATH=%QTDIR%\plugins\platforms\

• to use it, drag your gui.exe file and drop it on the RunWithQt.bat in explorer,
• or call RunWithQt gui.exe from the command line

The source code for ASP.NET AJAX is available for your reference, so you can pick through it and include the parts you want to continue using into a separate JS file. Or, you can port them to jQuery.

Here is the format function...

String.format = function() {
  var s = arguments[0];
  for (var i = 0; i < arguments.length - 1; i++) {       
    var reg = new RegExp("\\{" + i + "\\}", "gm");             
    s = s.replace(reg, arguments[i + 1]);
  }

  return s;
}

And here are the endsWith and startsWith prototype functions...

String.prototype.endsWith = function (suffix) {
  return (this.substr(this.length - suffix.length) === suffix);
}

String.prototype.startsWith = function(prefix) {
  return (this.substr(0, prefix.length) === prefix);
}

Change your constructor to pass true as the second argument.

TextWriter tsw = new StreamWriter(@"C:\Hello.txt", true);

The default namespace in Python is "__main__". When you use import scipy, Python creates a separate namespace as your module name. The rule in Pyhton is: when you want to call an attribute from another namespaces you have to use the fully qualified attribute name.

char originalString[] = "THESTRINGHASNOSPACES";

    char aux[5];
    int j=0;
    for(int i=0;i<strlen(originalString);i++){
        aux[j] = originalString[i];
        if(j==3){
            aux[j+1]='\0'; 
            printf("%s\n",aux);
            j=0;
        }else{
            j++;
        }

Please check your listenning ports with :

netstat -nat |grep :3306

If it show

 tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN 

Thats is ok for your remote connection.

But in this case i think you have

tcp        0     192.168.1.3:3306            0.0.0.0:*               LISTEN 

Thats is ok for your remote connection. You should also check your firewall (iptables if you centos/redhat)

services iptables stop

for testing or use :

iptables -A input -p tcp -i eth0 --dport 3306 -m state NEW,ESTABLISHED -j ACCEPT
iptables -A output -p tcp -i eth0 --sport 3306 -m state NEW,ESTABLISHED -j ACCEPT

And another thing to check your grant permission for remote connection :

GRANT ALL ON *.* TO remoteUser@'remoteIpadress' IDENTIFIED BY 'my_password';

If new does the job for you, then it will make your code modestly smaller as well. If you would otherwise call [[SomeClass alloc] init] in many different places in your code, you will create a Hot Spot in new's implementation - that is, in the objc runtime - that will reduce the number of your cache misses.

In my understanding, if you need to use a custom initializer use [[SomeClass alloc] initCustom].

If you don't, use [SomeClass new].

Every time you used the mysql console, the version is shown.

 mysql -u user

Successful console login shows the following which includes the mysql server version.

It's worth mentioning that if you have encountered something like this:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)

you can fix it by:

sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock

For input and button:

$('button').prop('disabled', true);

For anchor:

$('a').attr('disabled', true);

Checked in firefox, chrome.

See http://jsfiddle.net/czL54/2/

$('#3').remove();

Might not work with numeric id's though.

You can use something like this:
note: responseText returns server response and statusText returns the predefined
message for status error.for e.g:
responseText returns something like "Not Found (#404)" in some frameworks like Yii2 but
statusText returns "Not Found".

$.ajax({
    cache: false,
    url: "addInterview_Code.asp",
    type: "POST",
    datatype: "text",
    data: strData,
    success: function (html) {
        alert('successful : ' + html);
        $("#result").html("Successful");
    },
    error: function (data) {
        console.log(data.status + ':' + data.statusText,data.responseText);
    }
});

In Java 7 you can now just use Files.probeContentType(path).

I had the dependencies as specified @Greg post. I still faced the issue and could be able to resolve it by adding following additional jackson dependency:

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
    <version>2.7.4</version>
</dependency>

jQuery Mobile has a datepicker too. Source

Just include the following files,

  <script src="jQuery.ui.datepicker.js"></script>
  <script src="jquery.ui.datepicker.mobile.js"></script>

 window.open($('#myanchor').attr('href'));

               $('#myanchor')[0].click();

I encountered this using it in Mac, resolved it by using --ignore-platform-reqs option.

composer install --ignore-platform-reqs

How to debug a remote staging or production Spring Boot application

Server-side

Let's assume you have successfully followed Spring Boot's guide on setting up your Spring Boot application as a service. Your application artifact resides in /srv/my-app/my-app.war, accompanied by a configuration file /srv/my-app/my-app.conf:

# This is file my-app.conf
# What can you do in this .conf file? The my-app.war is prepended with a SysV init.d script
# (yes, take a look into the war file with a text editor). As my-app.war is symlinked in the init.d directory, that init.d script
# gets executed. One of its step is actually `source`ing this .conf file. Therefore we can do anything in this .conf file that
# we can also do in a regular shell script.

JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,address=localhost:8002,server=y,suspend=n"
export SPRING_PROFILES_ACTIVE=staging

When you restart your Spring Boot application with sudo service my-app restart, then in its log file located at /var/log/my-app.log should be a line saying Listening for transport dt_socket at address: 8002.

Client-side (developer machine)

Open an SSH port-forwarding tunnel to the server: ssh -L 8002:localhost:8002 [email protected]. Keep this SSH session running.

In Eclipse, from the toolbar, select Run -> Debug Configurations -> select Remote Java Application -> click the New button -> select as Connection Type Standard (Socket Attach), as Host localhost, and as Port 8002 (or whatever you have configured in the steps before). Click Apply and then Debug.

The Eclipse debugger should now connect to the remote server. Switching to the Debug perspective should show the connected JVM and its threads. Breakpoints should fire as soon as they are remotely triggered.

UPDATE: I suggest using a solution with filters, provided by @Jess.

I would write a method for that, and then where you need to format price you can just put the method in the template and pass value down

methods: {
    formatPrice(value) {
        let val = (value/1).toFixed(2).replace('.', ',')
        return val.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".")
    }
}

And then in template:

<template>
    <div>
        <div class="panel-group"v-for="item in list">
            <div class="col-md-8">
                <small>
                   Total: <b>{{ formatPrice(item.total) }}</b>
                </small>
            </div>
        </div>
    </div>
</template>

BTW - I didn't put too much care on replacing and regular expression. It could be improved.enter code here

Vue.filter('tableCurrency', num => {_x000D_
  if (!num) {_x000D_
    return '0.00';_x000D_
  }_x000D_
  const number = (num / 1).toFixed(2).replace(',', '.');_x000D_
  return number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ',');_x000D_
});

If your on jQuery 1.3+ then use .live()

Binds a handler to an event (like click) for all current - and future - matched element. Can also bind custom events.

You might try turning off pooling, which is enabled by default. See this discussion for more information.

import pyodbc
pyodbc.pooling = False
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 

csr = conn.cursor()  
csr.close()
del csr

print scalar grep { defined $_ } @a;

I had this exact problem, it was caused by a 20 item array literal. Had to switch to different syntax. Pretty silly.

You can use the sort command:

sort -k2 -n yourfile

-n, --numeric-sort compare according to string numerical value

For example:

$ cat ages.txt 
Bob 12
Jane 48
Mark 3
Tashi 54

$ sort -k2 -n ages.txt 
Mark 3
Bob 12
Jane 48
Tashi 54

If you want to see the full paths, I would recommend to cd to the top directory (of your drive if using windows)

cd C:\
grep -r somethingtosearch C:\Users\Ozzesh\temp

Or on Linux:

cd /
grep -r somethingtosearch ~/temp

if you really resist on your file name filtering (*.log) AND you want recursive (files are not all in the same directory), combining find and grep is the most flexible way:

cd /
find ~/temp -iname '*.log' -type f -exec grep somethingtosearch '{}' \;

you can also try with this answer :

 <img src="~/Content/img/@Html.DisplayFor(model =>model.ImagePath)" style="height:200px;width:200px;"/>

Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:

var mvar = "";
$(".mbox").each(function() {
    console.log($(this).html());
    mvar += $(this).html();
});
console.log(mvar);

The default value for bool is false. See this table for a great reference on default values. The only reason it would not be false when you check it is if you initialize/set it to true.

How about this?

$( document ).ready(function() {
    $('#fixed').width($('#wrap').width());
});

By using jquery you can set any kind of width :)

EDIT: As stated by dream in the comments, using JQuery just for this effect is pointless and even counter productive. I made this example for people who use JQuery for other stuff on their pages and consider using it for this part also. I apologize for any inconvenience my answer caused.

The difference between absolute and relative imports come into play only when you import a module from a package and that module imports an other submodule from that package. See the difference:

$ mkdir pkg
$ touch pkg/__init__.py
$ touch pkg/string.py
$ echo 'import string;print(string.ascii_uppercase)' > pkg/main1.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pkg/main1.py", line 1, in <module>
    import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
>>> 
$ echo 'from __future__ import absolute_import;import string;print(string.ascii_uppercase)' > pkg/main2.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 

In particular:

$ python2 pkg/main2.py
Traceback (most recent call last):
  File "pkg/main2.py", line 1, in <module>
    from __future__ import absolute_import;import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 
$ python2 -m pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ

Note that python2 pkg/main2.py has a different behaviour then launching python2 and then importing pkg.main2 (which is equivalent to using the -m switch).

If you ever want to run a submodule of a package always use the -m switch which prevents the interpreter for chaining the sys.path list and correctly handles the semantics of the submodule.

Also, I much prefer using explicit relative imports for package submodules since they provide more semantics and better error messages in case of failure.

I’ve been struggling with this for a while now. Dycey’s solution is correct in that specifying the src multiple times outputs the same thing in your css file. However, this seems to break in OSX Firefox 23 (probably other versions too, but I don’t have time to test).

The cross-browser @font-face solution from Font Squirrel looks like this:

@font-face {
    font-family: 'fontname';
    src: url('fontname.eot');
    src: url('fontname.eot?#iefix') format('embedded-opentype'),
         url('fontname.woff') format('woff'),
         url('fontname.ttf') format('truetype'),
         url('fontname.svg#fontname') format('svg');
    font-weight: normal;
    font-style: normal;
}

To produce the src property with the comma-separated values, you need to write all of the values on one line, since line-breaks are not supported in Sass. To produce the above declaration, you would write the following Sass:

@font-face
  font-family: 'fontname'
  src: url('fontname.eot')
  src: url('fontname.eot?#iefix') format('embedded-opentype'), url('fontname.woff') format('woff'), url('fontname.ttf') format('truetype'), url('fontname.svg#fontname') format('svg')
  font-weight: normal
  font-style: normal

I think it seems silly to write out the path a bunch of times, and I don’t like overly long lines in my code, so I worked around it by writing this mixin:

=font-face($family, $path, $svg, $weight: normal, $style: normal)
  @font-face
    font-family: $family
    src: url('#{$path}.eot')
    src: url('#{$path}.eot?#iefix') format('embedded-opentype'), url('#{$path}.woff') format('woff'), url('#{$path}.ttf') format('truetype'), url('#{$path}.svg##{$svg}') format('svg')
    font-weight: $weight
    font-style: $style

Usage: For example, I can use the previous mixin to setup up the Frutiger Light font like this:

+font-face('frutigerlight', '../fonts/frutilig-webfont', 'frutigerlight')

In this line:

for name, email, lastname in unpaidMembers.items():

unpaidMembers.items() must have only two values per iteration.

Here is a small example to illustrate the problem:

This will work:

for alpha, beta, delta in [("first", "second", "third")]:
    print("alpha:", alpha, "beta:", beta, "delta:", delta)

This will fail, and is what your code does:

for alpha, beta, delta in [("first", "second")]:
    print("alpha:", alpha, "beta:", beta, "delta:", delta)

In this last example, what value in the list is assigned to delta? Nothing, There aren't enough values, and that is the problem.

More recent versions have a different syntax:

var table = $('#example').DataTable();

// #myInput is a <input type="text"> element
$('#myInput').on('keyup change', function () {
    table.search(this.value).draw();
});

Note that this example uses the variable table assigned when datatables is first initialised. If you don't have this variable available, simply use:

var table = $('#example').dataTable().api();

// #myInput is a <input type="text"> element
$('#myInput').on('keyup change', function () {
    table.search(this.value).draw();
});

Since: DataTables 1.10

– Source: https://datatables.net/reference/api/search()

Try not setting the options parameter

this.http.post(${this.apiEndPoint}, formData)

and make sure you are not setting the globalHeaders in your Http factory.

Add height:100% to body

body{height:100%}

A monad is a thing used to encapsulate objects that have changing state. It is most often encountered in languages that otherwise do not allow you to have modifiable state (e.g., Haskell).

An example would be for file I/O.

You would be able to use a monad for file I/O to isolate the changing state nature to just the code that used the Monad. The code inside the Monad can effectively ignore the changing state of the world outside the Monad - this makes it a lot easier to reason about the overall effect of your program.

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

You can use --version and in that case it's not required to redirect to stdout

java --version | head -1 | cut -f2 -d' '

From java help

-version      print product version to the error stream and exit
--version     print product version to the output stream and exit

Since most developers are familiar with tag/annotation-based documentation, the convention I have started using is similar. Here is a taste:

{
  "@comment dependencies": [
    "These are the comments for the `dependencies` section.",
    "The name of the section being commented is included in the key after the `@comment` 'annotation'/'tag' to ensure the keys are unique.",
    "That is, using just \"@comment\" would not be sufficient to keep keys unique if you need to add another comment at the same level.",
    "Because JSON doesn't allow a multi-line string or understand a line continuation operator/character, just use an array for each line of the comment.",
    "Since this is embedded in JSON, the keys should be unique.",
    "Otherwise JSON validators, such as ones built into IDEs, will complain.",
    "Or some tools, such as running `npm install something --save`, will rewrite the `package.json` file but with duplicate keys removed.",
    "",
    "@package react - Using an `@package` 'annotation` could be how you add comments specific to particular packages."
  ],
  "dependencies": {
    ...
  },
  "scripts": {
    "@comment build": "This comment is about the build script.",
    "build": "...",

    "@comment start": [
      "This comment is about the `start` script.",
      "It is wrapped in an array to allow line formatting.",
      "When using npm, as opposed to yarn, to run the script, be sure to add ` -- ` before adding the options.",
      "",
      "@option {number} --port - The port the server should listen on."
    ],
    "start": "...",

    "@comment test": "This comment is about the test script.",
    "test": "..."
  }
}

Note: For the dependencies, devDependencies, etc. sections, the comment annotations can't be added directly above the individual package dependencies inside the configuration object since npm is expecting the key to be the name of an npm package. Hence the reason for the @comment dependencies.

Note: In certain contexts, such as in the scripts object, some editors/IDEs may complain about the array. In the scripts context, Visual Studio Code expects a string for the value -- not an array.

I like the annotation/tag style way of adding comments to JSON because the @ symbol stands out from the normal declarations.

new File(fileName).getName();

or

int idx = fileName.replaceAll("\\\\", "/").lastIndexOf("/");
return idx >= 0 ? fileName.substring(idx + 1) : fileName;

Notice that the first solution is system dependent. It only takes the system's path separator character into account. So if your code runs on a Unix system and receives a Windows path, it won't work. This is the case when processing file uploads being sent by Internet Explorer.

the method modify() that you called in the last is called in global context if you want to override modify() you first have to inherit A or B.

Maybe you're trying to do this:

In this case C inherits A

function A() {
    this.modify = function() {
        alert("in A");
    }
}

function B() {
    this.modify = function() {
        alert("in B");
    }
}

C = function() {
    this.modify = function() {
        alert("in C");
    };

    C.prototype.modify(); // you can call this method where you need to call modify of the parent class
}

C.prototype = new A();

The method to fetch this list is already documented on Facebook's Developer site, you can make a whois call to see all IPs assigned to Facebook:

whois -h whois.radb.net -- '-i origin AS32934' | grep ^route

You can save your @change="onChange()" an use watchers. Vue computes and watches, it´s designed for that. In case you only need the value and not other complex Event atributes.

Something like:

  ...
  watch: {
    leaveType () {
      this.whateverMethod(this.leaveType)
    }
  },
  methods: {
     onChange() {
         console.log('The new value is: ', this.leaveType)
     }
  }

The dplyr select function selects specific columns from a data frame. To return unique values in a particular column of data, you can use the group_by function. For example:

library(dplyr)

# Fake data
set.seed(5)
dat = data.frame(x=sample(1:10,100, replace=TRUE))

# Return the distinct values of x
dat %>%
  group_by(x) %>%
  summarise() 

    x
1   1
2   2
3   3
4   4
5   5
6   6
7   7
8   8
9   9
10 10

If you want to change the column name you can add the following:

dat %>%
  group_by(x) %>%
  summarise() %>%
  select(unique.x=x)

This both selects column x from among all the columns in the data frame that dplyr returns (and of course there's only one column in this case) and changes its name to unique.x.

You can also get the unique values directly in base R with unique(dat$x).

If you have multiple variables and want all unique combinations that appear in the data, you can generalize the above code as follows:

set.seed(5)
dat = data.frame(x=sample(1:10,100, replace=TRUE), 
                 y=sample(letters[1:5], 100, replace=TRUE))

dat %>% 
  group_by(x,y) %>%
  summarise() %>%
  select(unique.x=x, unique.y=y)

You'll have to understand that the significance of element creation performance is irrelevant in the context of using jQuery in the first place.

Keep in mind, there's no real purpose of creating an element unless you're actually going to use it.

You may be tempted to performance test something like $(document.createElement('div')) vs. $('<div>') and get great performance gains from using $(document.createElement('div')) but that's just an element that isn't in the DOM yet.

However, in the end of the day, you'll want to use the element anyway so the real test should include f.ex. .appendTo();

Let's see, if you test the following against each other:

var e = $(document.createElement('div')).appendTo('#target');
var e = $('<div>').appendTo('#target');
var e = $('<div></div>').appendTo('#target');
var e = $('<div/>').appendTo('#target');

You will notice the results will vary. Sometimes one way is better performing than the other. And this is only because the amount of background tasks on your computer change over time.

Test yourself here

So, in the end of the day, you do want to pick the smallest and most readable way of creating an element. That way, at least, your script files will be smallest possible. Probably a more significant factor on the performance point than the way of creating an element before you use it in the DOM.

Explicit...

cursor foo is select * from blah; begin open fetch exit when close cursor yada yada yada

don't use them, use implicit

cursor foo is select * from blah;

for n in foo loop x = n.some_column end loop

I think you can even do this

for n in (select * from blah) loop...

Stick to implicit, they close themselves, they are more readable, they make life easy.

I tried to combine efficiency and simplicity and end up with this :

public static IEnumerable<T> TakeLast<T>(this IEnumerable<T> source, int count)
{
    if (source == null) { throw new ArgumentNullException("source"); }

    Queue<T> lastElements = new Queue<T>();
    foreach (T element in source)
    {
        lastElements.Enqueue(element);
        if (lastElements.Count > count)
        {
            lastElements.Dequeue();
        }
    }

    return lastElements;
}

About performance : In C#, Queue<T> is implemented using a circular buffer so there is no object instantiation done each loop (only when the queue is growing up). I did not set queue capacity (using dedicated constructor) because someone might call this extension with count = int.MaxValue . For extra performance you might check if source implement IList<T> and if yes, directly extract the last values using array indexes.

Hope this code will help

public class ThisFragment extends Fragment {

public Button button = null;
Intent intent;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.yourlayout, container, false);

    intent = new Intent(getActivity(), GoToThisActivity.class);
    button = (Button) rootView.findViewById(R.id.theButtonid);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(intent);
        }
    });
    return rootView;
}

You can use this code, make sure you change "ThisFragment" as your fragment name, "yourlayout" as the layout name, "GoToThisActivity" change it to which activity do you want and then "theButtonid" change it with your button id you used.

If you write an image gallery with ImageViews and ViewPager, that supports zoom and pan, see a simple solution described here: Implementing a zoomable ImageView by Extending the Default ViewPager in Phimpme Android (and Github sample - PhotoView). This solution doesn't work with ViewPager alone.

public class CustomViewPager extends ViewPager {
    public CustomViewPager(Context context) {
        super(context);
    }

    public CustomViewPager(Context context, AttributeSet attrs)
    {
        super(context,attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        try {
            return super.onInterceptTouchEvent(event);
        } catch (IllegalArgumentException e) {
            return false;
        }
    }
}

The worst thing of using just

console.log({'some stuff': 2} + '\n' + 'something')

is that all stuff are converted to the string and if you need object to show you may see next:

[object Object]

Thus my variant is the next code:

console.log({'some stuff': 2},'\n' + 'something');

The simplest and the coolest way I found was to use (it takes 2 minutes to setup):

https://ngrok.com/

It will work with anything running on localhost. Just signup, run little excutable and whatever you run on localhost gets public URL you can access from anywhere.

This is good for showing stuff to your remote team mates, no fiddling with IIS setup or firewalls. Want to stop access just terminate executable.

ngrok authtoken xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

ngrok http -host-header=localhost 89230

assuming that 89230 is your IIS Express port

You can also run multiple ports even on free plan

This is a comprehensive answer to this question. I have done this because this page is high on the Google search results and the answer does not go into enough detail. This post assumes that you are competent at using Visual Studio C# forms. This is based on VS2012.

1. Start by simply dragging a ContextMenuStrip onto the form. It will just put it into the top left corner where you can add your menu items and rename it as you see fit.

2. You will have to view code and enter in an event yourself on the form. Create a mouse down event for the item in question and then assign a right click event for it like so (I have called the ContextMenuStrip "rightClickMenuStrip"):

   private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
   {
   switch (e.Button)
       {
           case MouseButtons.Right:
           {
               rightClickMenuStrip.Show(this, new Point(e.X, e.Y));//places the menu at the pointer position
           }
           break;
       }
   }
   

3. Assign the event handler manually to the form.designer (you may need to add a "using" for System.Windows.Forms; You can just resolve it):

   this.pictureBox1.MouseDown += new MouseEventHandler(this.pictureBox1_MouseDown);
   

4. All that is needed at this point is to simply double click each menu item and do the desired operations for each click event in the same way you would for any other button.

This is the basic code for this operation. You can obviously modify it to fit in with your coding practices.

Use below Code, It worked for me.

<script type="text/javascript">
     $(document).ready(function () {
            $('#dialog').dialog({
                autoOpen: false,
                title: 'Basic Dialog'
            });
            $('#contactUs').click(function () {
                $('#dialog').dialog('open');
            });
        });
</script>

I think the answer by jpmc26, while by no means wrong, comes down too heavily on circular imports. They can work just fine, if you set them up correctly.

The easiest way to do so is to use import my_module syntax, rather than from my_module import some_object. The former will almost always work, even if my_module included imports us back. The latter only works if my_object is already defined in my_module, which in a circular import may not be the case.

To be specific to your case: Try changing entities/post.py to do import physics and then refer to physics.PostBody rather than just PostBody directly. Similarly, change physics.py to do import entities.post and then use entities.post.Post rather than just Post.

Actually, RFC 2965, the document that defines how cookies work, specifies that there should be no maximum length of a cookie's key or value size, and encourages implementations to support arbitrarily large cookies. Each browser's implementation maximum will necessarily be different, so consult individual browser documentation.

See section 5.3, "Implementation Limits", in the RFC.

Gnu GCC has a builtin function for comparing types __builtin_types_compatible_p.

https://gcc.gnu.org/onlinedocs/gcc-3.4.5/gcc/Other-Builtins.html

This built-in function returns 1 if the unqualified versions of the types type1 and type2 (which are types, not expressions) are compatible, 0 otherwise. The result of this built-in function can be used in integer constant expressions.

This built-in function ignores top level qualifiers (e.g., const, volatile). For example, int is equivalent to const int.

Used in your example:

double doubleVar;
if(__builtin_types_compatible_p(typeof(doubleVar), double)) {
    printf("doubleVar is of type double!");
}

There's typically two levels of buffering involved:

1. Internal buffers
2. Operating system buffers

The internal buffers are buffers created by the runtime/library/language that you're programming against and is meant to speed things up by avoiding system calls for every write. Instead, when you write to a file object, you write into its buffer, and whenever the buffer fills up, the data is written to the actual file using system calls.

However, due to the operating system buffers, this might not mean that the data is written to disk. It may just mean that the data is copied from the buffers maintained by your runtime into the buffers maintained by the operating system.

If you write something, and it ends up in the buffer (only), and the power is cut to your machine, that data is not on disk when the machine turns off.

So, in order to help with that you have the flush and fsync methods, on their respective objects.

The first, flush, will simply write out any data that lingers in a program buffer to the actual file. Typically this means that the data will be copied from the program buffer to the operating system buffer.

Specifically what this means is that if another process has that same file open for reading, it will be able to access the data you just flushed to the file. However, it does not necessarily mean it has been "permanently" stored on disk.

To do that, you need to call the os.fsync method which ensures all operating system buffers are synchronized with the storage devices they're for, in other words, that method will copy data from the operating system buffers to the disk.

Typically you don't need to bother with either method, but if you're in a scenario where paranoia about what actually ends up on disk is a good thing, you should make both calls as instructed.

Addendum in 2018.

Note that disks with cache mechanisms is now much more common than back in 2013, so now there are even more levels of caching and buffers involved. I assume these buffers will be handled by the sync/flush calls as well, but I don't really know.

double jhon = 3;
double[] numbers = new double[3];
for (int i = 0; i < 3; i++)

{
    numbers[i] = double.Parse(Console.ReadLine());

}
Console.WriteLine("\n");

Array.Sort(numbers);

for (int i = 0; i < 3; i++)
{
    Console.WriteLine(numbers[i]);

}

Console.ReadLine();

Suppose we have three anchor tags like ,

<a  href="ID=1" class="testClick">Test1.</a>
<br />
<a  href="ID=2" class="testClick">Test2.</a>
<br />
<a  href="ID=3" class="testClick">Test3.</a>

now in script

$(".testClick").click(function () {
        var anchorValue= $(this).attr("href");
        alert(anchorValue);
});

use this keyword instead of className (testClick)

res.send is used to send the response to the client where res.end is used to end the response you are sending.

res.send automatically call res.end So you don't have to call or mention it after res.send

Make sure your docker repositry name matches your local docker repo name. e.g lets say if you local repo name "kavashgar/nodjsapp"

then your should also have a repo names "kavashgar" in docker hub

You can use function colSums() to calculate sum of all values. [,-1] ensures that first column with names of people is excluded.

 colSums(people[,-1])
Height Weight 
   199    425

Assuming there could be multiple columns that are not numeric, or that your column order is not fixed, a more general approach would be:

colSums(Filter(is.numeric, people))

32-bit Java requires contiguous free space in memory to run. If you specify a large heap size, there may not be so much contiguous free space in memory even if you have much more free space available than necessary.

Installing a 64-bit version of Java helps in these cases, the contiguous memory requirements only applies to 32-bit Java.

use contentDocument to achieve this

var iframe = document.getElementById('iframeId');
var innerDoc = (iframe.contentDocument) 
               ? iframe.contentDocument 
               : iframe.contentWindow.document;

var ulObj = innerDoc.getElementById("ID_TO_SEARCH");

When using more +n that Matt already mentioned, to avoid pauses in long files, try this:

more +1 myfile.txt > con

When you redirect the output from more, it doesn't pause - and here you redirect to the console. You can similarly redirect to some other file like this w/o the pauses of more if that's your desired end result. Use > to redirect to file and overwrite it if it already exists, or >> to append to an existing file. (Can use either to redirect to con.)

You can also check whether an element is in set or not while inserting the element. The single element version return a pair, with its member pair::first set to an iterator pointing to either the newly inserted element or to the equivalent element already in the set. The pair::second element in the pair is set to true if a new element was inserted or false if an equivalent element already existed.

For example: Suppose the set already has 20 as an element.

 std::set<int> myset;
 std::set<int>::iterator it;
 std::pair<std::set<int>::iterator,bool> ret;

 ret=myset.insert(20);
 if(ret.second==false)
 {
     //do nothing

 }
 else
 {
    //do something
 }

 it=ret.first //points to element 20 already in set.

If the element is newly inserted than pair::first will point to the position of new element in set.

You can use ClassLoader.getResource method to get the correct resource.

URL res = getClass().getClassLoader().getResource("abc.txt");
File file = Paths.get(res.toURI()).toFile();
String absolutePath = file.getAbsolutePath();

OR

Although this may not work all the time, a simpler solution -

You can create a File object and use getAbsolutePath method:

File file = new File("resources/abc.txt");
String absolutePath = file.getAbsolutePath();

Someone I know created a portable version of IE8 using thinstall (now it's bought by vmware and called thinapp) (only 1.8 MB). Thinstall creates a virtualized application with a virtual filesystem builtin and is the perfect solution to DLL hell. The whole app runs from a single exe file.

This is untested against other versions install, I might add.

I tend to version my framework then apply the version number to script and style paths

<cfset fw.version = '001' />
<script src="/scripts/#fw.version#/foo.js"/>

Here is a link to an example using PDFSharp and ConcatenateDocuments

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

If Options -Indexes does not work as Bryan Drewery suggested, you could write a recursive method to create blank index.php files.

Place this inside of your base folder you wish to protect, you can name it whatever (I would recommend index.php)

<?php

recurse(".");

function recurse($path){
    foreach(scandir($path) as $o){
        if($o != "." && $o != ".."){
            $full = $path . "/" . $o;
            if(is_dir($full)){
                if(!file_exists($full . "/index.php")){
                    file_put_contents($full . "/index.php", "");
                }
                recurse($full);
            }
        }
    }
}

?>

These blank index.php files can be easily deleted or overwritten, and they'll keep your directories from being listable.

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

You can use the with template tag.

{% with name="World" %}     
<html>
<div>Hello {{name}}!</div>
</html>
{% endwith %}

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

If you happen to have IPython in your packages (you should), it has (up to now, anyway) a very nice formatter for durations (in float seconds). That is used in various places, for example by the %%time cell magic. I like the format it produces for short durations:

>>> from IPython.core.magics.execution import _format_time
>>> 
>>> for v in range(-9, 10, 2):
...     dt = 1.25 * 10**v
...     print(_format_time(dt))

1.25 ns
125 ns
12.5 µs
1.25 ms
125 ms
12.5 s
20min 50s
1d 10h 43min 20s
144d 16h 13min 20s
14467d 14h 13min 20s

This can be done using the numeric_limits in C++:

http://www.cplusplus.com/reference/limits/numeric_limits/

These are the methods you probably want to look at:

infinity()  T   Representation of positive infinity, if available.
quiet_NaN() T   Representation of quiet (non-signaling) "Not-a-Number", if available.
signaling_NaN() T   Representation of signaling "Not-a-Number", if available.

To get unique and random looking tokens you could just encrypt your primary key i.e.:

SELECT HEX(AES_ENCRYPT(your_pk,'your_password')) AS 'token' FROM your_table;

This is good enough plus its reversable so you'd not have to store that token in your table but to generate it instead.

Another advantage is once you decode your PK from that token you do not have to do heavy full text searches over your table but simple and quick PK search.

Theres one small problem though. MySql supports different block encryption modes which if changed will completely change your token space making old tokens useless...

To overcome this one could set that variable before token generated i.e.:

SET block_encryption_mode = 'aes-256-cbc';

However that a bit waste... The solution for this is to attach an encryption mode used marker to the token:

SELECT CONCAT(CONV(CRC32(@@GLOBAL.block_encryption_mode),10,35),'Z',HEX(AES_ENCRYPT(your_pk,'your_password'))) AS 'token' FROM your_table;

Another problem may come up if you wish to persist that token in your table on INSERT because to generate it you need to know primary_key for the record which was not inserted yet... Ofcourse you might just INSERT and then UPDATE with LAST_INSERT_ID() but again - theres a better solution:

INSERT INTO your_table ( token )
SELECT CONCAT(CONV(CRC32(@@GLOBAL.block_encryption_mode),10,35),'Z',HEX(AES_ENCRYPT(your_pk,'your_password'))) AS 'token'
FROM information_schema.TABLES 
WHERE  TABLE_SCHEMA = DATABASE() AND TABLE_NAME = "your_table";

One last but not least advantage of this solution is you can easily replicate it in php, python, js or any other language you might use.

saving in any format is very much possible. Check following- http://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html

2ndly , What exactly you are expecting the save dialog to work , it works like that, Opening a doc file is very much possible- http://srikanthtechnologies.com/blog/openworddoc.html

This simple solution worked for me.

import 'rxjs/add/operator/pairwise';
import { Router } from '@angular/router';

export class TempComponent {
    constructor(private router: Router) {
        this.router.events.pairwise().subscribe((event) => {
            console.log(event); // NavigationEnd will have last and current visit url
        });
    };
}

yes java's timer can be used, but as the question asks for better way (for mobile). Which is explained Here.

For the sake of StackOverflow:

Since Timer creates a new thread it may be considered heavy,

if all you need is to get is a call back while the activity is running a Handler can be used in conjunction with a

Runnable:

private final int interval = 1000; // 1 Second
private Handler handler = new Handler();
private Runnable runnable = new Runnable(){
    public void run() {
        Toast.makeText(MyActivity.this, "C'Mom no hands!", Toast.LENGTH_SHORT).show();
    }
};
...
handler.postAtTime(runnable, System.currentTimeMillis()+interval);
handler.postDelayed(runnable, interval);

or a Message

private final int EVENT1 = 1; 
private Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) {         
        case Event1:
            Toast.makeText(MyActivity.this, "Event 1", Toast.LENGTH_SHORT).show();
            break;

        default:
            Toast.makeText(MyActivity.this, "Unhandled", Toast.LENGTH_SHORT).show();
            break;
        }
    }
};

...

Message msg = handler.obtainMessage(EVENT1);
handler.sendMessageAtTime(msg, System.currentTimeMillis()+interval);
handler.sendMessageDelayed(msg, interval);

on a side note this approach can be used, if you want to run a piece of code in the UI thread from an another thread.

if you need to get a call back even if your activity is not running then, you can use an AlarmManager

You can try like this:

var x= str== null 
        ? string.Empty 
        : str.Substring(0, Math.Min(5, str.Length));

I recommend dynamically adding the elements, and if using jQuery or other JavaScript library, it is quite simple:

• http://api.jquery.com/appendTo/
• http://api.jquery.com/prependTo/
• http://api.jquery.com/html/

also look at prepend and append. Otherwise if you have an image tag like that, and you want to make it validate, then you might consider using a dummy image, such as a 1px transparent gif or png.

Ask this questions yourself? And you will decide your DB selection.

1. Do you need master-master? Then CouchDB. Mainly CouchDB supports master-master replication which anticipates nodes being disconnected for long periods of time. MongoDB would not do well in that environment.
2. Do you need MAXIMUM R/W throughput? Then MongoDB
3. Do you need ultimate single-server durability because you are only going to have a single DB server? Then CouchDB.
4. Are you storing a MASSIVE data set that needs sharding while maintaining insane throughput? Then MongoDB.
5. Do you need strong consistency of data? Then MongoDB.
6. Do you need high availability of database? Then CouchDB.
7. Are you hoping multi databases and multi tables/ collections? Then MongoDB
8. You have a mobile app offline users and want to sync their activity data to a server? Then you need CouchDB.
9. Do you need large variety of querying engine? Then MongoDB
10. Do you need large community to be using DB? Then MongoDB

well in mysql 5.5 , like operator is insensitive...so if your vale is elm or ELM or Elm or eLM or any other , and you use like '%elm%' , it will list all the matching values.

I cant say about earlier versions of mysql.

If you go in Oracle , like work as case-sensitive , so if you type like '%elm%' , it will go only for this and ignore uppercases..

Strange , but this is how it is :)

Here's a windows bat file I wrote which combines Vincent and Pauls suggestions. It prompts the user for source and destination names.

Just modify the variables at the top to set the proper paths to your executables / database ports.

:: Creates a copy of a database with a different name.
:: User is prompted for Src and destination name.
:: Fair Warning: passwords are passed in on the cmd line, modify the script with -p instead if security is an issue.
:: Uncomment the rem'd out lines if you want script to prompt for database username, password, etc.

:: See also: http://stackoverflow.com/questions/1887964/duplicate-entire-mysql-database

From the OP:

Instead of converting my whole Dictionary, i decided to keep my obj dynamic the whole time. When i access the keys and values of my Dictionary with a foreach later, i use foreach(dynamic key in obj.Keys) and convert the keys and values to strings simply.

Java has a assert statement, the JVM disables assertion validation by default. They must be explicitly enabled using command line argument -enableassertions (or its shorthand -ea),

while JavaScript supports console.assert(), it's just a logging method and won't interrupt current procedure if assertion failed.

To bring things together and satisfy various needs, here is a tiny js assertion lib.

globalThis.assert = (()=> {
  class AssertionError extends Error {
    constructor(message) {
      super(message);
      this.name = 'AssertionError';
    }
  }
  let config = {
    async: true,
    silent: false
  };
  function assert(condition, message = undefined) {
    if (!condition) {
      if (config.silent) {
        //NOOP
      } else if (config.async) {
        console.assert(condition, message || 'assert');
      } else {
        throw new AssertionError(message || 'assertion failed');
      }
    }
  }
  assert.config = config;
  return assert;
})();


/* global assert */
Object.assign(assert.config, {
  // silent: true, // to disable assertion validation
  async: false, // to validate assertion synchronously (will interrupt if assertion failed, like Java's)
});

let items = [
  {id: 1},
  {id: 2},
  {id: 3}
];
function deleteItem(item) {
  let index = items.findIndex((e)=> e.id === item.id);
  assert(index > -1, `index should be >=0, the item(id=${item.id}) to be deleted doesn't exist, or was already deleted`);
  items.splice(index, 1);
}

console.log('begin');
deleteItem({id: 1});
deleteItem({id: 1});
console.log('end');

Here is a good example in Python3.

  >>> a = input("What is your name?")
  What is your name?Peter

  >>> b = input("Where are you from?")
  Where are you from?DE

  >>> print("So you are %s of %s" % (a, b))
  So you are Peter of DE

For a loop where you want to convert an array of strings to an array of bigIntegers do this:

String[] unsorted = new String[n]; //array of Strings
BigInteger[] series = new BigInteger[n]; //array of BigIntegers

for(int i=0; i<n; i++){
    series[i] = new BigInteger(unsorted[i]); //convert String to bigInteger
}

For me texBoxName.Clear();is the best method because I have textboxs in binding and if I use other methods I do not have a good day

I have written down the steps:

? Add gem 'newrelic_rpm' to your Gemfile under staging & production
? bundle install
? Login to heroku control panel and add newrelic addon
? Once added, setup automatic pinging to your website so that it does not idle
? Browse to Menu > Availability Monitoring (under Settings) ? Click “Turn on Availability Monitoring”
? Enter the url to ping (eg: http://spokenvote.org)
? Select 1 minute for the interval

Using regular for loop is the simplest way of printing array in my opinion. Here you have a sample code based on your intArray

for (int i = 0; i < intArray.length; i++) {
   System.out.print(intArray[i] + ", ");
}

It gives output as yours 1, 2, 3, 4, 5

jQuery(".success_mgs").show(); setTimeout(function(){ jQuery(".success_mgs").hide();},5000);

Since we are talking about having every element exactly once, a "set" makes more sense to me.

Example with classes and IEqualityComparer implemented:

 public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }

        public Product(int x, string y)
        {
            Id = x;
            Name = y;
        }
    }

    public class ProductCompare : IEqualityComparer<Product>
    {
        public bool Equals(Product x, Product y)
        {  //Check whether the compared objects reference the same data.
            if (Object.ReferenceEquals(x, y)) return true;

            //Check whether any of the compared objects is null.
            if (Object.ReferenceEquals(x, null) || Object.ReferenceEquals(y, null))
                return false;

            //Check whether the products' properties are equal.
            return x.Id == y.Id && x.Name == y.Name;
        }
        public int GetHashCode(Product product)
        {
            //Check whether the object is null
            if (Object.ReferenceEquals(product, null)) return 0;

            //Get hash code for the Name field if it is not null.
            int hashProductName = product.Name == null ? 0 : product.Name.GetHashCode();

            //Get hash code for the Code field.
            int hashProductCode = product.Id.GetHashCode();

            //Calculate the hash code for the product.
            return hashProductName ^ hashProductCode;
        }
    }

Now

List<Product> originalList = new List<Product> {new Product(1, "ad"), new Product(1, "ad")};
var setList = new HashSet<Product>(originalList, new ProductCompare()).ToList();

setList will have unique elements

I thought of this while dealing with .Except() which returns a set-difference

I cheated, but I believe this is the only answer that addresses every requirement. Namely, this avoids the trailing CRLF, provides a place for the other operation to complete in the meantime, and properly redirects to stdout as necessary.

Restarting the SQL Server will clear up the log space used by your database. If this however is not an option, you can try the following:

* Issue a CHECKPOINT command to free up log space in the log file.

* Check the available log space with DBCC SQLPERF('logspace'). If only a small 
  percentage of your log file is actually been used, you can try a DBCC SHRINKFILE 
  command. This can however possibly introduce corruption in your database. 

* If you have another drive with space available you can try to add a file there in 
  order to get enough space to attempt to resolve the issue.

Hope this will help you in finding your solution.

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:

You can put your servers in the default_step group and those vars will apply to it:

# inventory file
[default_step]
prod2
web_v2

Then just move your default_step.yml file to group_vars/default_step.yml.

SELECT INTO is typically used to generate temp tables or to copy another table (data and/or structure).

In day to day code you use INSERT because your tables should already exist to be read, UPDATEd, DELETEd, JOINed etc. Note: the INTO keyword is optional with INSERT

That is, applications won't normally create and drop tables as part of normal operations unless it is a temporary table for some scope limited and specific usage.

A table created by SELECT INTO will have no keys or indexes or constraints unlike a real, persisted, already existing table

The 2 aren't directly comparable because they have almost no overlap in usage

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).

When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization can convert these complex objects into byte strings for such use. After the byte strings are transmitted, the receiver will have to recover the original object from the byte string. This is known as deserialization.

Say, you have an object:

{foo: [1, 4, 7, 10], bar: "baz"}

serializing into JSON will convert it into a string:

'{"foo":[1,4,7,10],"bar":"baz"}'

which can be stored or sent through wire to anywhere. The receiver can then deserialize this string to get back the original object. {foo: [1, 4, 7, 10], bar: "baz"}.

json_encode is available in php > 5.2.0:

echojson_encode($row);

Below mechanism helps in redirecting multiple lines to file. Keep complete string under " so that we can redirect values of the variable.

#!/bin/bash
kernel="2.6.39"
echo "line 1, ${kernel}
line 2," > a.txt
echo 'line 2, ${kernel}
line 2,' > b.txt

Content of a.txt is

line 1, 2.6.39
line 2,

Content of b.txt is

line 2, ${kernel}
line 2,

I had same error. First I update cocoapods using

sudo gem install cocoapods

then install pods using Pod install command worked for me.

I usually just run ez_setup.py. IIRC, that works fine, at least with UAC off.

It also creates an easy_install executable in your Python\scripts subdirectory, which should be in your PATH.

UPDATE: I highly recommend not to bother with easy_install anymore! Jump right to pip, it's better in every regard!
Installation is just as simple: from the installation instructions page, you can download get-pip.py and run it. Works just like the ez_setup.py mentioned above.

Try to do all the steps specified in the link below and before that upgrade VirtualBox to 4.2 by following the instructions in VirtualBox 4.2.0 Released With Support For Drag'n'drop From Host To Linux Guests, More. Then upgrade Genymotion to the latest version.

Go to the desktop and run Genymotion. Select a virtual device with Android version 4.2 and then drag and drop the two files Genymotion-ARM-Translation_v1.1.zip first. Then Genymotion will show progress and after this it will promt a dialog. Then click OK and it will ask to reboot the device. Restart ADB. Do the same steps for the second file, gapps-jb-20130812-signed.zip and restart ADB.

I hope this will resolve the issue. Check this link - it explains it clearer.

You need to use '2011-12-07' as the end point as a date without a time default to time 00:00:00.

So what you have actually written is interpreted as:

 SELECT users.* 
 FROM   users
 WHERE  created_at >= '2011-12-01 00:00:00' 
   AND  created_at <= '2011-12-06 00:00:00'

And your time stamp is: 2011-12-06 10:45:36 which is not between those points.
Change this too:

 SELECT users.* 
 FROM   users
 WHERE  created_at >= '2011-12-01'  -- Implied 00:00:00
   AND  created_at <  '2011-12-07'  -- Implied 00:00:00 and smaller than 
                                   --                  thus any time on 06

To avoid blank line skipping just replace this:

echo !modified! >> %OUTTEXTFILE%

with this:

echo.!modified! >> %OUTTEXTFILE%

The best way to compare 2 strings ignoring the case of the letters is to use the String.Equals static method specifying an ordinal ignore case string comparison. This is also the fastest way, much faster than converting the strings to lower or upper case and comparing them after that.

I tested the performance of both approaches and the ordinal ignore case string comparison was more than 9 times faster! It is also more reliable than converting strings to lower or upper case (check out the Turkish i problem). So always use the String.Equals method to compare strings for equality:

String.Equals(string1, string2, StringComparison.OrdinalIgnoreCase);

If you want to perform a culture specific string comparison you can use the following code:

String.Equals(string1, string2, StringComparison.CurrentCultureIgnoreCase);

Please note that the second example uses the the string comparison logic of the current culture, which makes it slower than the "ordinal ignore case" comparison in the first example, so if you don't need any culture specific string comparison logic and you are after maximum performance, use the "ordinal ignore case" comparison.

For more information, read the full story on my blog.

Comparable defines a natural ordering. What this means is that you're defining it when one object should be considered "less than" or "greater than".

Suppose you have a bunch of integers and you want to sort them. That's pretty easy, just put them in a sorted collection, right?

TreeSet<Integer> m = new TreeSet<Integer>(); 
m.add(1);
m.add(3);
m.add(2);
for (Integer i : m)
... // values will be sorted

But now suppose I have some custom object, where sorting makes sense to me, but is undefined. Let's say, I have data representing districts by zipcode with population density, and I want to sort them by density:

public class District {
  String zipcode; 
  Double populationDensity;
}

Now the easiest way to sort them is to define them with a natural ordering by implementing Comparable, which means there's a standard way these objects are defined to be ordered.:

public class District implements Comparable<District>{
  String zipcode; 
  Double populationDensity;
  public int compareTo(District other)
  {
    return populationDensity.compareTo(other.populationDensity);
  }
}

Note that you can do the equivalent thing by defining a comparator. The difference is that the comparator defines the ordering logic outside the object. Maybe in a separate process I need to order the same objects by zipcode - in that case the ordering isn't necessarily a property of the object, or differs from the objects natural ordering. You could use an external comparator to define a custom ordering on integers, for example by sorting them by their alphabetical value.

Basically the ordering logic has to exist somewhere. That can be -

• in the object itself, if it's naturally comparable (extends Comparable -e.g. integers)

• supplied in an external comparator, as in the example above.

I'd use SimpleXMLElement.

<?php

$xml = new SimpleXMLElement('<xml/>');

for ($i = 1; $i <= 8; ++$i) {
    $track = $xml->addChild('track');
    $track->addChild('path', "song$i.mp3");
    $track->addChild('title', "Track $i - Track Title");
}

Header('Content-type: text/xml');
print($xml->asXML());

I use this if the exe is supposed to be called by double clicking it

var thisPath = System.IO.Directory.GetCurrentDirectory();

If I get you right, you need ..\..\src

If you want to authenticate against a user name and password and without an authorization cookie, the MVC4 Authorize attribute won't work out of the box. However, you can add the following helper method to your controller to accept basic authentication headers. Call it from the beginning of your controller's methods.

void EnsureAuthenticated(string role)
{
    string[] parts = UTF8Encoding.UTF8.GetString(Convert.FromBase64String(Request.Headers.Authorization.Parameter)).Split(':');
    if (parts.Length != 2 || !Membership.ValidateUser(parts[0], parts[1]))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "No account with that username and password"));
    if (role != null && !Roles.IsUserInRole(parts[0], role))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "An administrator account is required"));
}

From the client side, this helper creates a HttpClient with the authentication header in place:

static HttpClient CreateBasicAuthenticationHttpClient(string userName, string password)
{
    var client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(userName + ':' + password)));
    return client;
}

This depends on a lot of things, such as what is the size of the file, what is its type (text/binary) etc. Some time ago I benchmarked the following function against versions using streambuf iterators - it was about twice as fast:

unsigned int FileRead( std::istream & is, std::vector <char> & buff ) {
    is.read( &buff[0], buff.size() );
    return is.gcount();
}

void FileRead( std::ifstream & ifs, string & s ) {
    const unsigned int BUFSIZE = 64 * 1024; // reasoable sized buffer
    std::vector <char> buffer( BUFSIZE );

    while( unsigned int n = FileRead( ifs, buffer ) ) {
        s.append( &buffer[0], n );
    }
}

my solution to the problem: in footer add <script src="//cdnjs.cloudflare.com/ajax/libs/jquery-form-validator/2.3.26/jquery.form-validator.min.js"></script>

If you don't mind importing the json module, then the best way to handle it is through json.JSONDecodeError (or json.decoder.JSONDecodeError as they are the same) as using default errors like ValueError could catch also other exceptions not necessarily connected to the json decode one.

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want

//EDIT (Oct 2020):

As @Jacob Lee noted in the comment, there could be the basic common TypeError raised when the JSON object is not a str, bytes, or bytearray. Your question is about JSONDecodeError, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want
except TypeError as e:
    # do whatever you want in this case

sizeof str is 7 - five bytes for the "Hello" text, plus the explicit NUL terminator, plus the implicit NUL terminator.

strlen(str) is 5 - the five "Hello" bytes only.

The key here is that the implicit nul terminator is always added - even if the string literal just happens to end with \0. Of course, strlen just stops at the first \0 - it can't tell the difference.

There is one exception to the implicit NUL terminator rule - if you explicitly specify the array size, the string will be truncated to fit:

char str[6] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 6 (with one NUL)
char str[7] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 7 (with two NULs)
char str[8] = "Hello\0"; // strlen(str) = 5, sizeof(str) = 8 (with three NULs per C99 6.7.8.21)

This is, however, rarely useful, and prone to miscalculating the string length and ending up with an unterminated string. It is also forbidden in C++.

Valid numbers for ports are: 0 to 2^16-1 = 0 to 65535
That is because a port number is 16 bit length.

However ports are divided into:
Well-known ports: 0 to 1023 (used for system services e.g. HTTP, FTP, SSH, DHCP ...)
Registered/user ports: 1024 to 49151 (you can use it for your server, but be careful some famous applications: like Microsoft SQL Server database management system (MSSQL) server or Apache Derby Network Server are already taking from this range i.e. it is not recommended to assign the port of MSSQL to your server otherwise if MSSQL is running then your server most probably will not run because of port conflict )
Dynamic/private ports: 49152 to 65535. (not used for the servers rather the clients e.g. in NATing service)

In programming you can use any numbers 0 to 65535 for your server, however you should stick to the ranges mentioned above, otherwise some system services or some applications will not run because of port conflict.
Check the list of most ports here: https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

I think that you'll probably have to use $.ajax() if you want to change the encoding, see the contentType param below (the success and error callbacks assume you have <div id="success"></div> and <div id="error"></div> in the html):

$.ajax({
    type: "POST",
    url: "SomePage.aspx/GetSomeObjects",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: "{id: '" + someId + "'}",
    success: function(json) {
        $("#success").html("json.length=" + json.length);
        itemAddCallback(json);
    },
    error: function (xhr, textStatus, errorThrown) {
        $("#error").html(xhr.responseText);
    }
});

I actually just had to do this about an hour ago, what a coincidence!

Assuming, var friend = { firstName: 'Harry', lastName: 'Potter' };

There are two options you have:

Update the model in-memory, and save (plain javascript array.push):

person.friends.push(friend);
person.save(done);

or

PersonModel.update(
    { _id: person._id }, 
    { $push: { friends: friend } },
    done
);

I always try and go for the first option when possible, because it'll respect more of the benefits that mongoose gives you (hooks, validation, etc.).

However, if you are doing lots of concurrent writes, you will hit race conditions where you'll end up with nasty version errors to stop you from replacing the entire model each time and losing the previous friend you added. So only go to the former when it's absolutely necessary.

You simply need to start mysql and feed it with the content of db.sql:

mysql -u user -p < db.sql

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

Two possible issues could be

• you either forgot to include Servlet jar in your classpath
• you forgot to import it in your Servlet class

To include Servlet jar in your class path in eclipse, Download the latest Servlet Jar and configure using buildpath option. look at this Link for more info.

If you have included the jar make sure that your import is declared.

import javax.servlet.http.HttpServletResponse

For saving Current time to firebase database I use Unic Epoch Conversation:

let timestamp = NSDate().timeIntervalSince1970

and For Decoding Unix Epoch time to Date().

let myTimeInterval = TimeInterval(timestamp)
let time = NSDate(timeIntervalSince1970: TimeInterval(myTimeInterval))

 WebConfigurationManager.ConnectionStrings["YourConnectionString"].ProviderName;

You would probably want this. Simplest solution would be

Create file first.

open file via

f = open('<filename>', 'w')

or

f = open('<filename>', 'a')

in case you want to append to file

Now, write to the same file via

f.write(<text to be written>)

Close the file after you are done using it

#good pracitice
f.close()

To run an executable in mac

1). Move to the path of the file:

cd/PATH_OF_THE_FILE

2). Run the following command to set the file's executable bit using the chmod command:

chmod +x ./NAME_OF_THE_FILE

3). Run the following command to execute the file:

./NAME_OF_THE_FILE

Once you have run these commands, going ahead you just have to run command 3, while in the files path.

I just tried the same and came up with following solution:

public enum Countries {
    TEXAS,
    FLORIDA,
    OKLAHOMA,
    KENTUCKY;

    private static Countries[] list = Countries.values();

    public static Countries getCountry(int i) {
        return list[i];
    }

    public static int listGetLastIndex() {
        return list.length - 1;
    }
}

The class has it's own values saved inside an array, and I use the array to get the enum at indexposition. As mentioned above arrays begin to count from 0, if you want your index to start from '1' simply change these two methods to:

public static String getCountry(int i) {
    return list[(i - 1)];
}

public static int listGetLastIndex() {
    return list.length;
}

Inside my Main I get the needed countries-object with

public static void main(String[] args) {
   int i = Countries.listGetLastIndex();
   Countries currCountry = Countries.getCountry(i);
}

which sets currCountry to the last country, in this case Countries.KENTUCKY.

Just remember this code is very affected by ArrayOutOfBoundsExceptions if you're using hardcoded indicies to get your objects.

The modern way:

pip install -U requests[socks]

then

import requests

resp = requests.get('http://go.to', 
                    proxies=dict(http='socks5://user:pass@host:port',
                                 https='socks5://user:pass@host:port'))

What about the Checked event? Combine that with AttachedCommandBehaviors or something similar, and a DelegateCommand to get a function fired in your viewmodel everytime that event is called.

I think you should avoid writing side-effecting method. Return true or false from your method and you can check these methods in unit tests.

This arstechnica article describes the basic steps:

Start by visiting the program portal and make sure that your developer certificate is up to date. It expires every six months and, if you haven't requested that a new one be issued, you cannot submit software to App Store. For most people experiencing the "pink upload of doom," though, their certificates are already valid. What next?

Open your Xcode project and check that you've set the active SDK to one of the device choices, like Device - 2.2. Accidentally leaving the build settings to Simulator can be a big reason for the pink rejection. And that happens more often than many developers would care to admit.

Next, make sure that you've chosen a build configuration that uses your distribution (not your developer) certificate. Check this by double-clicking on your target in the Groups & Files column on the left of the project window. The Target Info window will open. Click the Build tab and review your Code Signing Identity. It should be iPhone Distribution: followed by your name or company name.

You may also want to confirm your application identifier in the Properties tab. Most likely, you'll have set the identifier properly when debugging with your developer certificate, but it never hurts to check.

The top-left of your project window also confirms your settings and configuration. It should read something like "Device - 2.2 | Distribution". This shows you the active SDK and configuration.

If your settings are correct but you still aren't getting that upload finished properly, clean your builds. Choose Build > Clean (Command-Shift-K) and click Clean. Alternatively, you can manually trash the build folder in your Project from Finder. Once you've cleaned, build again fresh.

If this does not produce an app that when zipped properly loads to iTunes Connect, quit and relaunch Xcode. I'm not kidding. This one simple trick solves more signing problems and "pink rejections of doom" than any other solution already mentioned.

outgoing url in mvc generated based on the current routing schema.

because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.

to solve this problem you should use UrlParameter.Optional:

 <a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>

From Wikipedia:

[In] an XML document or external parsed entity, a CDATA section is a section of element content that is marked for the parser to interpret as only character data, not markup.

http://en.wikipedia.org/wiki/CDATA

Thus: text inside CDATA is seen by the parser but only as characters not as XML nodes.

We may need to check internet connectivity more than once. So it will be easier for us if we write the code block in an extension method of Context. Below are my helper extensions for Context and Fragment.

Checking Internet Connection

fun Context.hasInternet(): Boolean {
    val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    return if (Build.VERSION.SDK_INT < 23) {
        val activeNetworkInfo = connectivityManager.activeNetworkInfo
        activeNetworkInfo != null && activeNetworkInfo.isConnected
    } else {
        val nc = connectivityManager.getNetworkCapabilities(connectivityManager.activeNetwork)
        if (nc == null) {
            false
        } else {
            nc.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) ||
                    nc.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)
        }
    }
}

Other Extensions

fun Context.hasInternet(notifyNoInternet: Boolean = true, trueFunc: (internet: Boolean) -> Unit) {
    if (hasInternet()) {
        trueFunc(true)
    } else if (notifyNoInternet) {
        Toast.makeText(this, "No Internet Connection!", Toast.LENGTH_SHORT).show()
    }
}

fun Context.hasInternet(
    trueFunc: (internet: Boolean) -> Unit,
    falseFunc: (internet: Boolean) -> Unit
) {
    if (hasInternet()) {
        trueFunc(true)
    } else {
        falseFunc(true)
    }
}

fun Fragment.hasInternet(): Boolean = context!!.hasInternet()

fun Fragment.hasInternet(notifyNoInternet: Boolean = true, trueFunc: (internet: Boolean) -> Unit) =
    context!!.hasInternet(notifyNoInternet, trueFunc)

fun Fragment.hasInternet(
    trueFunc: (internet: Boolean) -> Unit, falseFunc: (internet: Boolean) -> Unit
) = context!!.hasInternet(trueFunc, falseFunc)

The only way I could get it to work in ALL scenarios (except Protected sheets) (based on Farham's Answer):

It supports:

• Scanning Hidden Row / Columns

• Ignores formatted cells with no data / formula

Code:

// Unhide All Cells and clear formats
sheet.Columns.ClearFormats();
sheet.Rows.ClearFormats();

// Detect Last used Row - Ignore cells that contains formulas that result in blank values
int lastRowIgnoreFormulas = sheet.Cells.Find(
                "*",
                System.Reflection.Missing.Value,
                InteropExcel.XlFindLookIn.xlValues,
                InteropExcel.XlLookAt.xlWhole,
                InteropExcel.XlSearchOrder.xlByRows,
                InteropExcel.XlSearchDirection.xlPrevious,
                false,
                System.Reflection.Missing.Value,
                System.Reflection.Missing.Value).Row;
// Detect Last Used Column  - Ignore cells that contains formulas that result in blank values
int lastColIgnoreFormulas = sheet.Cells.Find(
                "*",
                System.Reflection.Missing.Value,
                System.Reflection.Missing.Value,
                System.Reflection.Missing.Value,
                InteropExcel.XlSearchOrder.xlByColumns,
                InteropExcel.XlSearchDirection.xlPrevious,
                false,
                System.Reflection.Missing.Value,
                System.Reflection.Missing.Value).Column;

// Detect Last used Row / Column - Including cells that contains formulas that result in blank values
int lastColIncludeFormulas = sheet.UsedRange.Columns.Count;
int lastColIncludeFormulas = sheet.UsedRange.Rows.Count;

There is no difference.

The Java Software Development Kit (Java SDK) used to be called the Java Development Kit (JDK) before the marketing department at Sun got crazy with the "tm" and terminology. For political reasons & for sanity, they call the meaningful names (jdk) & versions (1.2 / 1.3 / 1.4 1.5 / 1.6) "engineering" terms. The marketing terms are "Java2 platform" (aka jdk 1.2 thru 1.4) or Java5 (aka jdk 1.5) or Java6 (aka jdk1.6). I'm getting a headache just thinking about it.

Put the DataGrid in a Grid, DockPanel, ContentControl or directly in the Window. A vertically-oriented StackPanel will give its children whatever vertical space they ask for - even if that means it is rendered out of view.

As of spring boot 2 the server.contextPath property is deprecated. Instead you should use server.servlet.contextPath.

So in your application.properties file add:

server.servlet.contextPath=/myWebApp

For more details see: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#servlet-specific-server-properties

For disabling all the database related autoconfiguration and exit from:

Cannot determine embedded database driver class for database type NONE

1. Using annotation:

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(PayPalApplication.class, args);
    }
}

2. Using Application.properties:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration, org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

To upload files to your repo without using the command-line, simply type this after your repository name in the browser:

https://github.com/yourname/yourrepositoryname/upload/master

and then drag and drop your files.(provided you are on github and the repository has been created beforehand)

I am not sure 100%, but try to replace selector with "html, body":

html, body 
{
   background: black;
   color: white;
   font-family: Chaparral Pro, lucida grande, verdana, sans-serif;
}

This is how i registered my domain:

sudo letsencrypt --apache -d mydomain.com

Then it was possible to use the same command with additional domains and follow the instructions:

sudo letsencrypt --apache -d mydomain.com,x.mydomain.com,y.mydomain.com

You can always use Request.QueryString collection like Web forms, but you can also make MVC handle them and pass them as parameters. This is the suggested way as it's easier and it will validate input data type automatically.

TCPDF 5.9.010 (2010-10-27) - Support for CSS properties 'border-spacing' and 'padding' for tables were added.

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.
