oh, that's a tough one. What you have here, basically, is two values for each item. Then you are trying to call them with a number as the key. Unfortunately, one of your values is already set as the key!
Try this:
colors = {1: ["blue", "5"], 2: ["red", "6"], 3: ["yellow", "8"]}
Now you can call the keys by number as if they are indexed like a list. You can also reference the color and number by their position within the list.
For example,
colors[1][0]
// returns 'blue'
colors[3][1]
// returns '8'
Of course, you will have to come up with another way of keeping track of what location each color is in. Maybe you can have another dictionary that stores each color's key as it's value.
colors_key = {'blue': 1, 'red': 6, 'yllow': 8}
Then, you will be able to also look up the colors key if you need to.
colors[colors_key['blue']][0] will return 'blue'
Something like that.
And then, while you're at it, you can make a dict with the number values as keys so that you can always use them to look up your colors, you know, if you need.
values = {5: [1, 'blue'], 6: [2, 'red'], 8: [3, 'yellow']}
Then, (colors[colors_key[values[5][1]]][0]) will return 'blue'.
Or you could use a list of lists.
Good luck!
If you do not find interest in overriding save
method, you can do
model_fields = [f.name for f in YourModel._meta.get_fields()]
valid_data = {
key: new_data[key]
for key in model_fields
if key in new_data.keys()
}
for (key, value) in valid_data.items():
if getattr(instance, key) != value:
print ('Data has changed')
setattr(instance, key, value)
instance.save()
you are in wrong cdb/pdb so connect to right pdb
Thanks to this post, my full css for cross browser happiness is:
<style>
.backgroundpic {
background-image: url('img/home.jpg');
background-size: cover;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='img/home.jpg',
sizingMethod='scale');
}
</style>
It's been so long since I've worked on this piece of code, but I'd like to add for more browser compatibility I've appended this to my CSS for more browser compatibility:
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
Here's an update to what Richard did that adds a "depth" indicator. The output is level-0, level-1, level-2, etc.
class UL_Class_Walker extends Walker_Nav_Menu {
function start_lvl(&$output, $depth) {
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<ul class=\"level-".$depth."\">\n";
}
}
If you're using Python 2.5, this won't work, but for people using 2.6 or 2.7, try
from __future__ import print_function
print("abcd", end='')
print("efg")
results in
abcdefg
For those using 3.x, this is already built-in.
List(Of String)
will handle that, mostly - though you need to either use AddRange
to add a collection of items, or Add
to add one at a time:
lstOfString.Add(String1)
lstOfString.Add(String2)
lstOfString.Add(String3)
lstOfString.Add(String4)
If you're adding known values, as you show, a good option is to use something like:
Dim inputs() As String = { "some value", _
"some value2", _
"some value3", _
"some value4" }
Dim lstOfString as List(Of String) = new List(Of String)(inputs)
' ...
Dim s3 = lstOfStrings(3)
This will still allow you to add items later as desired, but also get your initial values in quickly.
Edit:
In your code, you need to fix the declaration. Change:
Dim lstWriteBits() As List(Of String)
To:
Dim lstWriteBits As List(Of String)
Currently, you're declaring an Array of List(Of String) objects.
Another option:
=MID(A1,2,LEN(A1)-2)
Or this (for fun):
=RIGHT(LEFT(A1,LEN(A1)-1),LEN(LEFT(A1,LEN(A1)-1))-1)
Assuming the data file is actually Tab separated, not space aligned:
<test.tsv awk '{print $4}' | sort | uniq
Where $4 will be:
Considering there might be several img
tags I would recommend re.findall
:
import re
with open("sample.txt", 'r') as f_in, open('writetest.txt', 'w') as f_out:
for line in f_in:
for img in re.findall('<img[^>]+>', line):
print >> f_out, "yo it's a {}".format(img)
Since it is your files in your app bundle, I think you can use pathForResource:ofType:
to get the full pathname of your file.
Here is an example:
NSString* filePath = [[NSBundle mainBundle] pathForResource:@"your_file_name"
ofType:@"the_file_extension"];
Yes You can compile and execute without main method By using static block. But after static block executed (printed) you will get an error saying no main method found.
And Latest INFO --> YOU cant Do this with JAVA 7 version. IT will not execute.
{
static
{
System.out.println("Hello World!");
System.exit(0); // prevents “main method not found” error
}
}
But this will not execute with JAVA 7 version.
Here is an example that lists all the files on my desktop. you should change the path variable to your path.
Instead of printing the file's name with System.out.println, you should place your own code to operate on the file.
public static void main(String[] args) {
File path = new File("c:/documents and settings/Zachary/desktop");
File [] files = path.listFiles();
for (int i = 0; i < files.length; i++){
if (files[i].isFile()){ //this line weeds out other directories/folders
System.out.println(files[i]);
}
}
}

The /etc/apache2/httpd.conf
is empty in Ubuntu, because the Apache configuration resides in /etc/apache2/apache2.conf
!
“httpd.conf is for user options.” No it isn't, it's there for historic reasons.
Using Apache server, all user options should go into a new *.conf
-file inside /etc/apache2/conf.d/
. This method should be "update-safe", as httpd.conf
or apache2.conf
may get overwritten on the next server update.
Inside /etc/apache2/apache2.conf
, you will find the following line, which includes those files:
# Include generic snippets of statements
Include conf.d/
As of Apache 2.4+ the user configuration directory is /etc/apache2/conf-available/
. Use a2enconf FILENAME_WITHOUT_SUFFIX
to enable the new configuration file or manually create a symlink in /etc/apache2/conf-enabled/
. Be aware that as of Apache 2.4 the configuration files must have the suffix .conf
(e.g. conf-available/my-settings.conf
);
Another intuitive solution could be:
class Post
{
public $title;
public $date;
}
$posts = array();
$posts[0] = new Post();
$posts[0]->title = 'post sample 1';
$posts[0]->date = '1/1/2021';
$posts[1] = new Post();
$posts[1]->title = 'post sample 2';
$posts[1]->date = '2/2/2021';
foreach ($posts as $post) {
echo 'Post Title:' . $post->title . ' Post Date:' . $post->date . "\n";
}

You won't be able to convert it directly to long because of the decimal point i think you should convert it into decimal and then convert it into long something like this:
String strValue[i] = "1100.25";
long l1 = Convert.ToInt64(Convert.ToDecimal(strValue));
hope this helps!
This article explains all the details http://kunststube.net/encoding/
WRITING TO BUFFER
if you write to a 4 byte buffer, symbol ?
with UTF8 encoding, your binary will look like this:
00000000 11100011 10000001 10000010
if you write to a 4 byte buffer, symbol ?
with UTF16 encoding, your binary will look like this:
00000000 00000000 00110000 01000010
As you can see, depending on what language you would use in your content this will effect your memory accordingly.
e.g. For this particular symbol: ?
UTF16 encoding is more efficient since we have 2 spare bytes to use for the next symbol. But it doesn't mean that you must use UTF16 for Japan alphabet.
READING FROM BUFFER
Now if you want to read the above bytes, you have to know in what encoding it was written to and decode it back correctly.
e.g. If you decode this :
00000000 11100011 10000001 10000010
into UTF16 encoding, you will end up with ?
not ?
Note: Encoding and Unicode are two different things. Unicode is the big (table) with each symbol mapped to a unique code point. e.g. ?
symbol (letter) has a (code point): 30 42 (hex). Encoding on the other hand, is an algorithm that converts symbols to more appropriate way, when storing to hardware.
30 42 (hex) - > UTF8 encoding - > E3 81 82 (hex), which is above result in binary.
30 42 (hex) - > UTF16 encoding - > 30 42 (hex), which is above result in binary.
The official way to set the disabled
attribute on an HTMLInputElement
is this:
var input = document.querySelector('[name="myButton"]');
// Without querySelector API
// var input = document.getElementsByName('myButton').item(0);
// disable
input.setAttribute('disabled', true);
// enable
input.removeAttribute('disabled');
While @kaushar's answer is sufficient for enabling and disabling an HTMLInputElement
, and is probably preferable for cross-browser compatibility due to IE's historically buggy setAttribute
, it only works because Element
properties shadow Element
attributes. If a property is set, then the DOM uses the value of the property by default rather than the value of the equivalent attribute.
There is a very important difference between properties and attributes. An example of a true HTMLInputElement
property is input.value
, and below demonstrates how shadowing works:
var input = document.querySelector('#test');_x000D_
_x000D_
// the attribute works as expected_x000D_
console.log('old attribute:', input.getAttribute('value'));_x000D_
// the property is equal to the attribute when the property is not explicitly set_x000D_
console.log('old property:', input.value);_x000D_
_x000D_
// change the input's value property_x000D_
input.value = "My New Value";_x000D_
_x000D_
// the attribute remains there because it still exists in the DOM markup_x000D_
console.log('new attribute:', input.getAttribute('value'));_x000D_
// but the property is equal to the set value due to the shadowing effect_x000D_
console.log('new property:', input.value);
_x000D_
<input id="test" type="text" value="Hello World" />
_x000D_
That is what it means to say that properties shadow attributes. This concept also applies to inherited properties on the prototype
chain:
function Parent() {_x000D_
this.property = 'ParentInstance';_x000D_
}_x000D_
_x000D_
Parent.prototype.property = 'ParentPrototype';_x000D_
_x000D_
// ES5 inheritance_x000D_
Child.prototype = Object.create(Parent.prototype);_x000D_
Child.prototype.constructor = Child;_x000D_
_x000D_
function Child() {_x000D_
// ES5 super()_x000D_
Parent.call(this);_x000D_
_x000D_
this.property = 'ChildInstance';_x000D_
}_x000D_
_x000D_
Child.prototype.property = 'ChildPrototype';_x000D_
_x000D_
logChain('new Parent()');_x000D_
_x000D_
log('-------------------------------');_x000D_
logChain('Object.create(Parent.prototype)');_x000D_
_x000D_
log('-----------');_x000D_
logChain('new Child()');_x000D_
_x000D_
log('------------------------------');_x000D_
logChain('Object.create(Child.prototype)');_x000D_
_x000D_
// below is for demonstration purposes_x000D_
// don't ever actually use document.write(), eval(), or access __proto___x000D_
function log(value) {_x000D_
document.write(`<pre>${value}</pre>`);_x000D_
}_x000D_
_x000D_
function logChain(code) {_x000D_
log(code);_x000D_
_x000D_
var object = eval(code);_x000D_
_x000D_
do {_x000D_
log(`${object.constructor.name} ${object instanceof object.constructor ? 'instance' : 'prototype'} property: ${JSON.stringify(object.property)}`);_x000D_
_x000D_
object = object.__proto__;_x000D_
} while (object !== null);_x000D_
}
_x000D_
I hope this clarifies any confusion about the difference between properties and attributes.
The ab (apache bench) tool allows you to send many requests to a single page and you specify how many clients you want to be used and how many concurrent connection you want.
This may be the first step when developing a site. Just test some pages with a specific load. This way of benchmarking may have some problem, like caching being over used.
Later you may want a tool that simulate some concrete traffic and not for a single page. I don't have a refence handy on such tool yet.
Use curl --data-urlencode
; from man curl
:
This posts data, similar to the other
--data
options with the exception that this performs URL-encoding. To be CGI-compliant, the<data>
part should begin with a name followed by a separator and a content specification.
Example usage:
curl \
--data-urlencode "paramName=value" \
--data-urlencode "secondParam=value" \
http://example.com
See the man page for more info.
This requires curl 7.18.0 or newer (released January 2008). Use curl -V
to check which version you have.
You can as well encode the query string:
curl -G \
--data-urlencode "p1=value 1" \
--data-urlencode "p2=value 2" \
http://example.com
# http://example.com?p1=value%201&p2=value%202
I have given the comparison of all three discussed above.
Using values
%timeit df['value'] = df['a'].values % df['c'].values
139 µs ± 1.91 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
Without values
%timeit df['value'] = df['a']%df['c']
216 µs ± 1.86 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
Apply function
%timeit df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)
474 µs ± 5.07 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
Using docker-compose
, you can inherit env variables in docker-compose.yml and subsequently any Dockerfile(s) called by docker-compose
to build images. This is useful when the Dockerfile
RUN
command should execute commands specific to the environment.
(your shell has RAILS_ENV=development
already existing in the environment)
docker-compose.yml:
version: '3.1'
services:
my-service:
build:
#$RAILS_ENV is referencing the shell environment RAILS_ENV variable
#and passing it to the Dockerfile ARG RAILS_ENV
#the syntax below ensures that the RAILS_ENV arg will default to
#production if empty.
#note that is dockerfile: is not specified it assumes file name: Dockerfile
context: .
args:
- RAILS_ENV=${RAILS_ENV:-production}
environment:
- RAILS_ENV=${RAILS_ENV:-production}
Dockerfile:
FROM ruby:2.3.4
#give ARG RAILS_ENV a default value = production
ARG RAILS_ENV=production
#assign the $RAILS_ENV arg to the RAILS_ENV ENV so that it can be accessed
#by the subsequent RUN call within the container
ENV RAILS_ENV $RAILS_ENV
#the subsequent RUN call accesses the RAILS_ENV ENV variable within the container
RUN if [ "$RAILS_ENV" = "production" ] ; then echo "production env"; else echo "non-production env: $RAILS_ENV"; fi
This way, I don't need to specify environment variables in files or docker-compose
build
/up
commands:
docker-compose build
docker-compose up
You can also use the following code to open new page in new tab.
<asp:Button ID="Button1" runat="server" Text="Go"
OnClientClick="window.open('yourPage.aspx');return false;"
onclick="Button3_Click" />
And just call Response.Redirect("yourPage.aspx"); behind button event.
Try this.

As of Android versions M and N, following works for me and would be the correct approach. Emptying the ListView or setting the Adapter to null is not the right approach and would lead to null pointer issue, invalid ListView and/or crash of the app.
Simply do:
mList.clear();
mAdapter.notifyDataSetChanged();
i.e. first you clear the list altogether, and then let the adapter know about this change. Android will take care of correctly updating the UI with an empty list. In my case, my list is an ArrayList.
In case you are doing this operation from a different thread, run this code on the UI thread:
runOnUiThread(mRunnable);
Where mRunnable would be:
Runnable mRunnable = new Runnable() {
public void run() {
mList.clear();
mAdapter.notifyDataSetChanged();
}
};;
I got the solution for onunload
in all browsers except Opera by changing the Ajax asynchronous request into synchronous request.
xmlhttp.open("POST","LogoutAction",false);
It works well for all browsers except Opera.
I don't know what version of CI you were using back in 2013, but I am using CI3 and I just tested with two null
parameters passed to limit()
and there was no LIMIT
or OFFSET
in the rendered query (I checked by using get_compiled_select()
).
This means that -- assuming your have correctly posted your coding attempt -- you don't need to change anything (or at least the old issue is no longer a CI issue).
If this was my project, this is how I would write the method to return an indexed array of objects or an empty array if there are no qualifying rows in the result set.
function nationList($limit = null, $start = null) {
// assuming the language value is sanitized/validated/whitelisted
return $this->db
->select('nation.id, nation.name_' . $this->session->userdata('language') . ' AS name')
->from('nation')
->order_by("name")
->limit($limit, $start)
->get()
->result();
}
These refinements remove unnecessary syntax, conditions, and the redundant loop.
For reference, here is the CI core code:
/**
* LIMIT
*
* @param int $value LIMIT value
* @param int $offset OFFSET value
* @return CI_DB_query_builder
*/
public function limit($value, $offset = 0)
{
is_null($value) OR $this->qb_limit = (int) $value;
empty($offset) OR $this->qb_offset = (int) $offset;
return $this;
}
So the $this->qb_limit
and $this->qb_offset
class objects are not updated because null
evaluates as true
when fed to is_null()
or empty()
.
Use purrr::has_element
to check against the value of a list element:
> x <- list(c(1, 2), c(3, 4))
> purrr::has_element(x, c(3, 4))
[1] TRUE
> purrr::has_element(x, c(3, 5))
[1] FALSE
Three methods in my mind:
1) Short test for a name in a path (I'm not sure this might be your case)
ls -a "path" | grep "name"
2) Short test for a string in a file
grep -R "string" "filepath"
3) Longer bash script using regex:
#!/bin/bash
declare file="content.txt"
declare regex="\s+string\s+"
declare file_content=$( cat "${file}" )
if [[ " $file_content " =~ $regex ]] # please note the space before and after the file content
then
echo "found"
else
echo "not found"
fi
exit
This should be quicker if you have to test multiple string on a file content using a loop for example changing the regex at any cicle.
If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?
By default the rotation point is the Canvas's (0,0) point, and my guess is that you may want to rotate it around the center. I did that:
protected void renderImage(Canvas canvas)
{
Rect dest,drawRect ;
drawRect = new Rect(0,0, mImage.getWidth(), mImage.getHeight());
dest = new Rect((int) (canvas.getWidth() / 2 - mImage.getWidth() * mImageResize / 2), // left
(int) (canvas.getHeight()/ 2 - mImage.getHeight()* mImageResize / 2), // top
(int) (canvas.getWidth() / 2 + mImage.getWidth() * mImageResize / 2), //right
(int) (canvas.getWidth() / 2 + mImage.getHeight()* mImageResize / 2));// bottom
if(!mRotate) {
canvas.drawBitmap(mImage, drawRect, dest, null);
} else {
canvas.save(Canvas.MATRIX_SAVE_FLAG); //Saving the canvas and later restoring it so only this image will be rotated.
canvas.rotate(90,canvas.getWidth() / 2, canvas.getHeight()/ 2);
canvas.drawBitmap(mImage, drawRect, dest, null);
canvas.restore();
}
}
You could use Enumerable#select:
clients.select{|key, hash| hash["client_id"] == "2180" }
#=> [["orange", {"client_id"=>"2180"}]]
Note that the result will be an array of all the matching values, where each is an array of the key and value.
I was trying to set up MediaWiki on my windows 7 pc and got this error.
My solution was to "create a global FastCGI handler mapping for php".
In Swift you can do something like this. Following condition will be true every time you reach end of the tableView
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.row+1 == postArray.count {
println("came to last row")
}
}
There is often the tip to use 'echo.'
But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.
You could use echo(
. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.
More about the different ECHO:/\
variants is at DOS tips: ECHO. FAILS to give text or blank line.
Just pass the function as the argument in the array of useEffect...
useEffect(() => {
functionName()
}, [functionName])
You can try this code. Fast, you can also include special characters
@echo off
set "str=[string]"
echo %str% > "%tmp%\STR"
for %%P in ("%TMP%\STR") do (set /a strlen=%%~zP-3)
echo String lenght: %strlen%
When you echo $array;
, the result is Array
, result[0]
then represents the first character in Array
which is A
.
One way to handle this problem would be like this:
ajax.php
<?php
$array = array(1,2,3,4,5,6);
foreach($array as $a)
echo $a.",";
?>
jquery code
$(function(){ /* short for $(document).ready(function(){ */
$('#prev').click(function(){
$.ajax({type: 'POST',
url: 'ajax.php',
data: 'id=testdata',
cache: false,
success: function(data){
var tmp = data.split(",");
$('#content1').html(tmp[0]);
}
});
});
});
no, but it runs fine on win64, and can create win64 .EXEs

Please take a look at the vue-mouseover package if you are not satisfied how does this code look:
<div
@mouseover="isMouseover = true"
@mouseleave="isMouseover = false"
/>
vue-mouseover provides a v-mouseover
directive that automaticaly updates the specified data context property when the cursor enters or leaves an HTML element the directive is attached to.
By default in the next example isMouseover
property will be true
when the cursor is over an HTML element and false
otherwise:
<div v-mouseover="isMouseover" />
Also by default isMouseover
will be initially assigned when v-mouseover
is attached to the div
element, so it will not remain unassigned before the first mouseenter
/mouseleave
event.
You can specify custom values via v-mouseover-value
directive:
<div
v-mouseover="isMouseover"
v-mouseover-value="customMouseenterValue"/>
or
<div
v-mouseover="isMouseover"
v-mouseover-value="{
mouseenter: customMouseenterValue,
mouseleave: customMouseleaveValue
}"
/>
Custom default values can be passed to the package via options object during setup.
button {
background:transparent;
border:none;
outline:none;
display:block;
height:200px;
width:200px;
cursor:pointer;
}
Give the height and width with respect to the image in the background.This removes the borders and color of a button.You might also need to position it absolute so you can correctly place it where you need.I cant help you further without posting you code
To make it truly invisible you have to set outline:none; otherwise there would be a blue outline in some browsers and you have to set display:block if you need to click it and set dimensions to it

Sounds like an error you would get when your forms authentication ticket has expired. What is the timeout period for your ticket? Is it set to sliding or absolute expiration?
I believe the default for the timeout is 20 minutes with sliding expiration so if a user gets authenticated and at some point doesn't hit your site for 20 minutes their ticket would be expired. If it is set to absolute expiration it will expire X number of minutes after it was issued where X is your timeout setting.
You can set the timeout and expiration policy (e.g. sliding, absolute) in your web/machine.config
under /configuration/system.web/authentication/forms
Try this
myDataTable.Select("[Name] is NULL OR [Name] <> 'n/a'" )

You can use guava's Sets.newSetFromMap(map)
to get one. Java 6 also has that method in java.util.Collections
Dependency required for jersey restful service and Tomcat is the server. where ${jersey.version} is 2.29.1

My preferred way to make Raise button with match parent is that wrap it with Container. below is sample code.
Container(
width: double.infinity,
child: RaisedButton(
onPressed: () {},
color: Colors.deepPurpleAccent[100],
child: Text(
"Continue",
style: TextStyle(color: Colors.white),
),
),
)
Both your examples are equivalent. However, the first one is less obvious and more "hacky", while the second one clearly states your intention.
int (*pointer)[280];
pointer = tab1;
pointer
points to an 1D array of 280 integers. In your assignment, you actually assign the first row of tab1
. This works since you can implicitly cast arrays to pointers (to the first element).
When you are using pointer[5][12]
, C treats pointer
as an array of arrays (pointer[5]
is of type int[280]
), so there is another implicit cast here (at least semantically).
In your second example, you explicitly create a pointer to a 2D array:
int (*pointer)[100][280];
pointer = &tab1;
The semantics are clearer here: *pointer
is a 2D array, so you need to access it using (*pointer)[i][j]
.
Both solutions use the same amount of memory (1 pointer) and will most likely run equally fast. Under the hood, both pointers will even point to the same memory location (the first element of the tab1
array), and it is possible that your compiler will even generate the same code.
The first solution is "more advanced" since one needs quite a deep understanding on how arrays and pointers work in C to understand what is going on. The second one is more explicit.
http://javahowto.blogspot.com/2006/05/javahome-vs-javahome.html
Control Panel > Java, Java tab, click the View button. In Runtime Parameters, put:

Or when you execute Java you can add that command line switch to the command:
java -Djava.home=PATH SomeJavaApp
I suggest you check out chunked
and disk.frame
. They both have functions for reading in CSVs chunk-by-chunk.
In particular, disk.frame::csv_to_disk.frame
may be the function you are after?
Loop through divs every 10 seconds.
$(function () {
var counter = 0,
divs = $('#div1, #div2, #div3');
function showDiv () {
divs.hide() // hide all divs
.filter(function (index) { return index == counter % 3; }) // figure out correct div to show
.show('fast'); // and show it
counter++;
}; // function to loop through divs and show correct div
showDiv(); // show first div
setInterval(function () {
showDiv(); // show next div
}, 10 * 1000); // do this every 10 seconds
});
WebElement select = driver.findElement(By.id("gender"));
List<WebElement> options = select.findElements(By.tagName("option"));
for (WebElement option : options) {
if("Germany".equals(option.getText()))
option.click();
}
You should be able to use chaining to execute the events in sequence, e.g.:
$('#target')
.bind('click',function(event) {
alert('Hello!');
})
.bind('click',function(event) {
alert('Hello again!');
})
.bind('click',function(event) {
alert('Hello yet again!');
});
I guess the below code is doing the same
$('#target')
.click(function(event) {
alert('Hello!');
})
.click(function(event) {
alert('Hello again!');
})
.click(function(event) {
alert('Hello yet again!');
});
Source: http://www.peachpit.com/articles/article.aspx?p=1371947&seqNum=3
TFM also says:
When an event reaches an element, all handlers bound to that event type for the element are fired. If there are multiple handlers registered, they will always execute in the order in which they were bound. After all handlers have executed, the event continues along the normal event propagation path.

This other comment about using a new network comes pretty close to the solution for me, and was working for a while, but I found a better way thanks to some talk over in another question
Create a network with:
docker network create your-network --subnet 172.24.24.0/24
Then, at the bottom of docker-compose.yaml, put this:
networks:
default:
external:
name: your-network
Done. No need to add networks to all container definitions etc. and you can re-use the network with other docker-compose files as well if you'd like.
Try this:
String urle = HOST + url + value;
Then return the values from:
urle.replace(" ", "%20").trim();
To print out an SQL query in Doctrine, use:
$query->getResult()->getSql();
One way without using external process forking is string manipulation, in a generic case it would look like this:
#start value
CNT=1
for [whatever iterative loop, seq, cat, find...];do
# number of 0s is at least the amount of decimals needed, simple concatenation
TEMP="000000$CNT"
# for example 6 digits zero padded, get the last 6 character of the string
echo ${TEMP:(-6)}
# increment, if the for loop doesn't provide the number directly
TEMP=$(( TEMP + 1 ))
done
This works quite well on WSL as well, where forking is a really heavy operation. I had a 110000 files list, using printf "%06d" $NUM
took over 1 minute, the solution above ran in about 1 second.
The Advanced Editor did not resolve my issue, instead I was forced to edit dtsx-file through notepad (or your favorite text/xml editor) and manually replace values in attributes to
length="0"
dataType="nText"
(I'm using unicode)
Always make a backup of the dtsx-file before you edit in text/xml mode.

Here is an excerpts from "Effective Python: 90 Specific Ways to Write Better Python" (Amazing book. I highly recommend it).
Things to Remember
? Define new class interfaces using simple public attributes and avoid defining setter and getter methods.
? Use @property to define special behavior when attributes are accessed on your objects, if necessary.
? Follow the rule of least surprise and avoid odd side effects in your @property methods.
? Ensure that @property methods are fast; for slow or complex work—especially involving I/O or causing side effects—use normal methods instead.
One advanced but common use of @property is transitioning what was once a simple numerical attribute into an on-the-fly calculation. This is extremely helpful because it lets you migrate all existing usage of a class to have new behaviors without requiring any of the call sites to be rewritten (which is especially important if there’s calling code that you don’t control). @property also provides an important stopgap for improving interfaces over time.
I especially like @property because it lets you make incremental progress toward a better data model over time.
@property is a tool to help you address problems you’ll come across in real-world code. Don’t overuse it. When you find yourself repeatedly extending @property methods, it’s probably time to refactor your class instead of further paving over your code’s poor design.? Use @property to give existing instance attributes new functionality.
? Make incremental progress toward better data models by using @property.
? Consider refactoring a class and all call sites when you find yourself using @property too heavily.
printAccountSummary: function()
{return "Welcome!" + "\n" + "Your balance is currently $1000 and your interest rate is 1%."}
};
console.log(savingsAccount.printAccountSummary()); // method
Prints:
Welcome!
Your balance is currently $1000 and your interest rate is 1%.
This happens because $cOTLdata
is not null but the index 'char_data'
does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.
To check whether the index exists or not you can use isset():
isset($cOTLdata['char_data'])
Which means the line should look something like this:
$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;
Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).
From my point of view this error "Error: Aesthetics must either be length one, or the same length as the data" refers to the argument aes(x,y) I tried the na.omit() and worked just fine to me.
To sum it up,in object oriented programming, everything is modeled into classes and objects. Classes contain properties and methods. Public, private and protected keywords are used to specify access to these members(properties and methods) of a class from other classes or other .dlls or even other applications.
You're missing an ending anchor.

This is happening because your current CUDA version doesn't support your current GCC version. You need to do the following:
Find the supported GCC version (in my case 5 for CUDA 9)
Install the supported GCC version
sudo apt-get install gcc-5
sudo apt-get install g++-5
Change the softlinks for GCC in the /usr/bin
directory
cd /usr/bin
sudo rm gcc
sudo rm g++
sudo ln -s /usr/bin/gcc-5 gcc
sudo ln -s /usr/bin/g++-5 g++
Change the softlinks for GCC in the /usr/local/cuda-9.0/bin
directory
cd /usr/local/cuda-9.0/bin
sudo rm gcc
sudo rm g++
sudo ln -s /usr/bin/gcc-5 gcc
sudo ln -s /usr/bin/g++-5 g++
Add -DCUDA_HOST_COMPILER=/usr/bin/gcc-5
to your setup.py
file, used for compilation
if torch.cuda.is_available() and CUDA_HOME is not None:
extension = CUDAExtension
sources += source_cuda
define_macros += [("WITH_CUDA", None)]
extra_compile_args["nvcc"] = [
"-DCUDA_HAS_FP16=1",
"-D__CUDA_NO_HALF_OPERATORS__",
"-D__CUDA_NO_HALF_CONVERSIONS__",
"-D__CUDA_NO_HALF2_OPERATORS__",
"-DCUDA_HOST_COMPILER=/usr/bin/gcc-5"
]
Remove the old build directory
rm -rd build/
Compile again by setting CUDAHOSTCXX=/usr/bin/gcc-5
CUDAHOSTCXX=/usr/bin/gcc-5 python setup.py build develop
Note: If you still get the gcc: error trying to exec 'cc1plus': execvp: no such file or directory
error after following these steps, try reinstalling the GCC like this and then compiling again:
sudo apt-get install --reinstall gcc-5
sudo apt-get install --reinstall g++-5

Use wordwrap()
to truncate the string without breaking words if the string is longer than 50 characters, and just add ...
at the end:
$str = $input;
if( strlen( $input) > 50) {
$str = explode( "\n", wordwrap( $input, 50));
$str = $str[0] . '...';
}
echo $str;
Otherwise, using solutions that do substr( $input, 0, 50);
will break words.
Here is how to do dump the database (with just the schema):
mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql
If you also want the data, remove the --no-data
option.
I saw this when changing rsync versions. In the older version, it worked to say:
rsync -e 'ssh ...
when the rsync.exe
and ssh.exe
were in the same directory.
With the newer version, I had to specify the path:
rsync -e './ssh ...
and it worked.
There is a trick to have both timestamps, but with a little limitation.
You can use only one of the definitions in one table. Create both timestamp columns like so:
create table test_table(
id integer not null auto_increment primary key,
stamp_created timestamp default '0000-00-00 00:00:00',
stamp_updated timestamp default now() on update now()
);
Note that it is necessary to enter null
into both columns during insert
:
mysql> insert into test_table(stamp_created, stamp_updated) values(null, null);
Query OK, 1 row affected (0.06 sec)
mysql> select * from test_table;
+----+---------------------+---------------------+
| id | stamp_created | stamp_updated |
+----+---------------------+---------------------+
| 2 | 2009-04-30 09:44:35 | 2009-04-30 09:44:35 |
+----+---------------------+---------------------+
2 rows in set (0.00 sec)
mysql> update test_table set id = 3 where id = 2;
Query OK, 1 row affected (0.05 sec) Rows matched: 1 Changed: 1 Warnings: 0
mysql> select * from test_table;
+----+---------------------+---------------------+
| id | stamp_created | stamp_updated |
+----+---------------------+---------------------+
| 3 | 2009-04-30 09:44:35 | 2009-04-30 09:46:59 |
+----+---------------------+---------------------+

Remove space between classes in css selector:
driver.find_element_by_css_selector('.button .c_button .s_button').click()
# ^ ^
=>
driver.find_element_by_css_selector('.button.c_button.s_button').click()
If you want to avoid the regex, or must target an earlier JVM, String.replace() will do:
str=str.replace("\r","").replace("\n","");
And to remove a CRLF pair:
str=str.replace("\r\n","");
The latter is more efficient than building a regex to do the same thing. But I think the former will be faster as a regex since the string is only parsed once.

In case you are willing to use Curl for the calls with JSON 2 and Spring 3.2.0 in hand checkout the FAQ here. As AnnotationMethodHandlerAdapter is deprecated and replaced by RequestMappingHandlerAdapter.
This is an adapter for HashMaps which I implemented for a recent project. Works in a way similart to what @SandyR does, but encapsulates conversion logic so you don't manually convert strings to a wrapper object.
I used Java 8 features but with a few changes, you can adapt it to previous versions. I tested it for most common scenarios, except new Java 8 stream functions.
Basically it wraps a HashMap, directs all functions to it while converting strings to/from a wrapper object. But I had to also adapt KeySet and EntrySet because they forward some functions to the map itself. So I return two new Sets for keys and entries which actually wrap the original keySet() and entrySet().
One note: Java 8 has changed the implementation of putAll method which I could not find an easy way to override. So current implementation may have degraded performance especially if you use putAll() for a large data set.
Please let me know if you find a bug or have suggestions to improve the code.

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.
But there are more important differences on the receiving side of things. When the receiver does a recv
(or read
) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.
Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.
Note: this code doesn't detect cancellation, it offers a way to circumvent the need to detect it in a common case in which people try to detect it.
I got here while looking for a solution for file uploads using a hidden input, I believe that this is the most common reason to look for a way to detect cancellation of file input (open file dialog -> if a file was selected then run some code, otherwise do nothing), here's my solution:
var fileSelectorResolve;
var fileSelector = document.createElement('input');
fileSelector.setAttribute('type', 'file');
fileSelector.addEventListener('input', function(){
fileSelectorResolve(this.files[0]);
fileSelectorResolve = null;
fileSelector.value = '';
});
function selectFile(){
if(fileSelectorResolve){
fileSelectorResolve();
fileSelectorResolve = null;
}
return new Promise(function(resolve){
fileSelectorResolve = resolve;
fileSelector.dispatchEvent(new MouseEvent('click'));
});
}
Note that if no file was selected then the first line will return only once selectFile()
is called again (or if you called fileSelectorResolve()
from elsewhere).
async function logFileName(){
const file = await selectFile();
if(!file) return;
console.log(file.name);
}
Another example:
async function uploadFile(){
const file = await selectFile();
if(!file) return;
// ... make an ajax call here to upload the file ...
}
This is an old post, but I thought I would add another method to do this:
var win = window.open("http://www.google.com");
var winClosed = setInterval(function () {
if (win.closed) {
clearInterval(winClosed);
foo(); //Call your function here
}
}, 250);
You don't have to modify the contents or use any event handlers from the child window.
Check that the web server has permissions to write to the "images/" directory
Reader they show at http://www.webqr.com/index.html works like a charm, but literaly, you need the one on the webpage, the github version it's really hard to make it work, however, it is possible. The best way to go is reverse-engineer the example shown at the webpage.
However, to edit and get the full potential out of it, it's not so easy. At some point I may post the stripped-down reverse-engineered QR reader, but in the meantime have some fun hacking the code.
Happy coding.

If you want to set null value using update query set column value to NULL (without quotes) update tablename set columnname = NULL
However, if you are directly editing field value inside mysql workbench then use (Esc + del) keystroke to insert null value into selected column
See the example:
mkdir test && echo "Something" > test/file
Shell will try to create directory test
and then, only if it was successfull will try create file inside it.
So you may interrupt a sequence of steps if one of them failed.
I've created a complete function to determine if object is empty.
It uses Object.keys
from ECMAScript 5 (ES5) functionality if possible to achieve the best performance (see compatibility table) and fallbacks to the most compatible approach for older engines (browsers).
/**
* Returns true if specified object has no properties,
* false otherwise.
*
* @param {object} object
* @returns {boolean}
*/
function isObjectEmpty(object)
{
if ('object' !== typeof object) {
throw new Error('Object must be specified.');
}
if (null === object) {
return true;
}
if ('undefined' !== Object.keys) {
// Using ECMAScript 5 feature.
return (0 === Object.keys(object).length);
} else {
// Using legacy compatibility mode.
for (var key in object) {
if (object.hasOwnProperty(key)) {
return false;
}
}
return true;
}
}
Here's the Gist for this code.
And here's the JSFiddle with demonstration and a simple test.
I hope it will help someone. Cheers!

Change the button to
<button id="search">Search</button>
and add the following script
var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
var keyWord = $('#Keyword').val();
$('#searchResults').load(url, { searchText: keyWord });
})
and modify the controller method to accept the search text
public ActionResult DisplaySearchResults(string searchText)
{
var model = // build list based on parameter searchText
return PartialView("SearchResults", model);
}
The jQuery .load
method calls your controller method, passing the value of the search text and updates the contents of the <div>
with the partial view.
Side note: The use of a <form>
tag and @Html.ValidationSummary()
and @Html.ValidationMessageFor()
are probably not necessary here. Your never returning the Index
view so ValidationSummary
makes no sense and I assume you want a null
search text to return all results, and in any case you do not have any validation attributes for property Keyword
so there is nothing to validate.
Edit
Based on OP's comments that SearchCriterionModel
will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit()
event
<input type="submit" value="Search" />
var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
if (!$(this).valid()) {
return false; // prevent the ajax call if validation errors
}
var form = $(this).serialize();
$('#searchResults').load(url, form);
return false; // prevent the default submit action
})
and the controller method would be
public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
var model = // build list based on the properties of criteria
return PartialView("SearchResults", model);
}
A method that I use is to load the table into R as a data.frame
, then use dbWriteTable
to push it to PostgreSQL. These two steps are shown below.
R's data.frame
objects are database-like, where named columns have explicit types, such as text or numbers. There are several ways to get a spreadsheet into R, such as XLConnect. However, a really simple method is to select the range of the Excel table (including the header), copy it (i.e. CTRL+C), then in R use this command to get it from the clipboard:
d <- read.table("clipboard", header=TRUE, sep="\t", quote="\"", na.strings="", as.is=TRUE)
If you have RStudio, you can easily view the d
object to make sure it is as expected.
Ensure you have RPostgreSQL installed from CRAN, then make a connection and send the data.frame
to the database:
library(RPostgreSQL)
conn <- dbConnect(PostgreSQL(), dbname="mydb")
dbWriteTable(conn, "some_table_name", d)
Now some_table_name
should appear in the database.
Some common clean-up steps can be done from pgAdmin or psql:
ALTER TABLE some_table_name RENAME "row.names" TO id;
ALTER TABLE some_table_name ALTER COLUMN id TYPE integer USING id::integer;
ALTER TABLE some_table_name ADD PRIMARY KEY (id);
Not easily done I am afraid. The problem is Css cannot replace the arrow in a select as this is rendered by the browser. But you can build a new control from div and input elements and Javascript to perform the same function as the select.
Try looking at some of the autocomplete plugins for Jquery for example.
Otherwise there is some info on the select element here:
http://www.devarticles.com/c/a/Web-Style-Sheets/Taming-the-Select/
Some color-syntaxing enrichment can be applied with the following blockcode syntax
```json
Here goes your json object definition
```
Note: This won't prettify the json representation. To do so, one can previously rely on an external service such as jsbeautifier.org and paste the prettified result in the wiki.
There is a possibility that somehow you have a non-unicode string with unicode escape characters, e.g.:
>>> print repr(text)
'I don\\u2018t like this'
This actually happened to me once before. You can use a unicode_escape
codec to decode the string to unicode and then encode it to any format you want:
>>> uni = text.decode('unicode_escape')
>>> print type(uni)
<type 'unicode'>
>>> print uni.encode('utf-8')
I don‘t like this
Probably, more intuitive way would be like this
if type(e) is list:
print('Found a list element inside the list')
I had a similar problem with my Gradle Project using Intelij. I solved it by deleting the .gradle (see screenshot below) Package and rebuilding the Project. .gradle Package
Well you can not run code from notepad so that means you are opening up the page from the file system. aka c:/foo/bar/hello.html
When you run the code from the asp.net page, you are running it from localhost. aka http://loalhost:1234/assdf.html
Each of these run in different security zones on IE.
As others have noted, in general use the -v
flag for the gem install
command.
If you're developing a gem locally, after cutting a gem from your gemspec:
$ gem install gemname-version.gem
Assuming version 0.8, it would look like this:
$ gem install gemname-0.8.gem
Enable "resolveJsonModule": true
in tsconfig.json
file and implement as below code, it's work for me:
const config = require('./config.json');
NumPy is not just more efficient; it is also more convenient. You get a lot of vector and matrix operations for free, which sometimes allow one to avoid unnecessary work. And they are also efficiently implemented.
For example, you could read your cube directly from a file into an array:
x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))
Sum along the second dimension:
s = x.sum(axis=1)
Find which cells are above a threshold:
(x > 0.5).nonzero()
Remove every even-indexed slice along the third dimension:
x[:, :, ::2]
Also, many useful libraries work with NumPy arrays. For example, statistical analysis and visualization libraries.
Even if you don't have performance problems, learning NumPy is worth the effort.
You can use below statement to write the contents of dataframe in CSV format
df.write.csv("/data/home/csv")
If you need to write the whole dataframe into a single CSV file, then use
df.coalesce(1).write.csv("/data/home/sample.csv")
For spark 1.x, you can use spark-csv to write the results into CSV files
Below scala snippet would help
import org.apache.spark.sql.hive.HiveContext
// sc - existing spark context
val sqlContext = new HiveContext(sc)
val df = sqlContext.sql("SELECT * FROM testtable")
df.write.format("com.databricks.spark.csv").save("/data/home/csv")
To write the contents into a single file
import org.apache.spark.sql.hive.HiveContext
// sc - existing spark context
val sqlContext = new HiveContext(sc)
val df = sqlContext.sql("SELECT * FROM testtable")
df.coalesce(1).write.format("com.databricks.spark.csv").save("/data/home/sample.csv")
Building upon the already compact solution from @Dan, here's a self-contained function version of it. Variable names are reduced to single letters for those who just want it to be as compact as possible at the expense of context.
const ns = {};
ns.sizeof = function(v) {
let f = ns.sizeof, //this needs to match the name of the function itself, since arguments.callee.name is defunct
o = {
"undefined": () => 0,
"boolean": () => 4,
"number": () => 8,
"string": i => 2 * i.length,
"object": i => !i ? 0 : Object
.keys(i)
.reduce((t, k) => f(k) + f(i[k]) + t, 0)
};
return o[typeof v](v);
};
ns.undef;
ns.bool = true;
ns.num = 1;
ns.string = "Hello";
ns.obj = {
first_name: 'Brendan',
last_name: 'Eich',
born: new Date(1961, 6, 4),
contributions: ['Netscape', 'JavaScript', 'Brave', 'BAT'],
politically_safe: false
};
console.log(ns.sizeof(ns.undef));
console.log(ns.sizeof(ns.bool));
console.log(ns.sizeof(ns.num));
console.log(ns.sizeof(ns.string));
console.log(ns.sizeof(ns.obj));
console.log(ns.sizeof(ns.obj.contributions));

Here you go. I have used this code with UIView, though. You should be able to make those adjustments for scrollview.
func addKeyboardNotifications() {
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillShow(notification:)),
name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillHide(notification:)),
name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
// if using constraints
// bottomViewBottomSpaceConstraint.constant = keyboardSize.height
self.view.frame.origin.y -= keyboardSize.height
UIView.animate(withDuration: duration) {
self.view.layoutIfNeeded()
}
}
}
func keyboardWillHide(notification: NSNotification) {
let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
//if using constraint
// bottomViewBottomSpaceConstraint.constant = 0
self.view.frame.origin.y = 0
UIView.animate(withDuration: duration) {
self.view.layoutIfNeeded()
}
}
Don't forget to remove notifications at right place.
func removeKeyboardNotifications() {
NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
replace
I know the accepted answer from four years ago works, but this seems a tad lighter than using replace
:
dt = datetime.date.today()
dt = datetime.datetime(dt.year, dt.month, dt.day)
Notes
datetime
object without passing time properties to the constructor, you get midnight.dt = datetime.datetime.now()
Following @Michelle Tilley solution, apparently it didn't work for me at first. Not sure why, maybe I am using chrome and different version of node. After did some minor tweaks, it is working for me now.
app.all('*', function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'PUT, GET, POST, DELETE, OPTIONS');
res.header('Access-Control-Allow-Headers', 'Content-Type');
next();
});
In case someone facing similar issue as mine, this might be helpful.
Encountered similar error. resetting chrome://net-internals/#hsts did not work for me. The issue was that my vm's clock was skewed by days. resetting the time did work out to resolve this issue. https://support.google.com/chrome/answer/4454607?hl=en
This can also happen when you're trying to load a DLL and that in turn needs another DLL which cannot be not found.
You need to use the scrollTop
property.
document.getElementById('box').scrollTop
@Neil's answer is one (perfectly valid!) way of doing it, but you can also simply call matplotlib.use('Agg')
before importing matplotlib.pyplot
, and then continue as normal.
E.g.
import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
fig.savefig('temp.png')
You don't have to use the Agg backend, as well. The pdf, ps, svg, agg, cairo, and gdk backends can all be used without an X-server. However, only the Agg backend will be built by default (I think?), so there's a good chance that the other backends may not be enabled on your particular install.
Alternately, you can just set the backend parameter in your .matplotlibrc
file to automatically have matplotlib.pyplot
use the given renderer.
PDO will make it a lot easier to scale if your site/web app gets really being as you can daily set up Master and slave connections to distribute the load across the database, plus PHP is heading towards moving to PDO as a standard.
For development you can use https://cors-anywhere.herokuapp.com , for production is better to set up your own proxy
async function read() {_x000D_
let r= await (await fetch('https://cors-anywhere.herokuapp.com/http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&q=http://feeds.feedburner.com/mathrubhumi')).json();_x000D_

If you use C++, and don't want to create the algorithm yourself, you can use Boost.Geometry. It uses an adapted version of the Weiler-Atherton algorithm mentioned above.
Another way to accomplish this is with the jq "--arg" flag. Using the original example:
#!/bin/sh
#this works ***
projectID=$(cat file.json | jq -r '.resource[] |
select(.username=="[email protected]") | .id')
echo "$projectID"
[email protected]
# Use --arg to pass the variable to jq. This should work:
projectID=$(cat file.json | jq --arg EMAILID $EMAILID -r '.resource[]
| select(.username=="$EMAILID") | .id')
echo "$projectID"
See here, which is where I found this solution: https://github.com/stedolan/jq/issues/626
Override all methods

This is just example using reflect.DeepEqual() that is given in @VictorDeryagin's answer.
package main
import (
"fmt"
"reflect"
)
func main() {
a := []int {4,5,6}
b := []int {4,5,6}
c := []int {4,5,6,7}
fmt.Println(reflect.DeepEqual(a, b))
fmt.Println(reflect.DeepEqual(a, c))
}
Result:
true
false

I had this error today and discovered it was an incorrectly-formatted year...
select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')
Notice the year has only three 'y's. It should have 4.
Double-check your format.
The prior value for the key is dropped and replaced with the new one.
If you'd like to keep all the values a key is given, you might consider implementing something like this:
import org.apache.commons.collections.MultiHashMap;
import java.util.Set;
import java.util.Map;
import java.util.Iterator;
import java.util.List;
public class MultiMapExample {
public static void main(String[] args) {
MultiHashMap mp=new MultiHashMap();
mp.put("a", 10);
mp.put("a", 11);
mp.put("a", 12);
mp.put("b", 13);
mp.put("c", 14);
mp.put("e", 15);
List list = null;
Set set = mp.entrySet();
Iterator i = set.iterator();
while(i.hasNext()) {
Map.Entry me = (Map.Entry)i.next();
list=(List)mp.get(me.getKey());
for(int j=0;j<list.size();j++)
{
System.out.println(me.getKey()+": value :"+list.get(j));
}
}
}
}
I had this same issue , but after a couple of research I fond it out it's quite simple to do,
Locate this URL in your Codeigniter project: application/helpers/util_helper.php
add this below code
//you can define any kind of function but I have queried database in my case
//check if the function exist
if (!function_exists('yourfunctionname')) {
function yourfunctionname($param (if neccesary)) {
//get the instance
$ci = & get_instance();
// write your query with the instance class
$data = $ci->db->select('*');
$data = $ci->db->from('table');
$data = $ci->db->where('something', 'something');
//you can return anythting
$data = $ci->db->get()->num_rows();
if ($data > 0) {
return $data;

In my case, I was getting this error because my table had
varchar(50)
but I was injecting 67 character long string, which resulted in thi error. Changing it to
varchar(255)
fixed the problem.

That should work.
Basically, with prepared statements the data coming in from a potential hacker is treated as data - and there's no way it can be intermixed with your application SQL and/or be interpreted as SQL (which can happen when data passed in is placed directly into your application SQL).
This is because prepared statements "prepare" the SQL query first to find an efficient query plan, and send the actual values that presumably come in from a form later - at that time the query is actually executed.
More great info here:
From the docs:
_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.
So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.
Edit: Further reading led me here:
http://www.analyticsmarket.com/blog/edit-ecommerce-data
Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.
you should use extend()
>>> c=[1,2,3]
>>> c.extend(c)
>>> c
[1, 2, 3, 1, 2, 3]
other info: append vs. extend

What version of Python do you use? 2.x or 3.x?

list
has a count
method:
>>> [True,True,False].count(True)

This is actually more efficient than sum
, as well as being more explicit about the intent, so there's no reason to use sum
:
In [1]: import random
In [2]: x = [random.choice([True, False]) for i in range(100)]
In [3]: %timeit x.count(True)
970 ns ± 41.1 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
In [4]: %timeit sum(x)
1.72 µs ± 161 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)
there is a good example in here to calculate distance with PHP http://www.geodatasource.com/developers/php :
function distance($lat1, $lon1, $lat2, $lon2, $unit) {
$theta = $lon1 - $lon2;
$dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta));
$dist = acos($dist);
$dist = rad2deg($dist);
$miles = $dist * 60 * 1.1515;
$unit = strtoupper($unit);
if ($unit == "K") {
return ($miles * 1.609344);
} else if ($unit == "N") {
return ($miles * 0.8684);
} else {
return $miles;
}
}
In Objective-C:
NSString *myString = myURL.absoluteString;
In Swift:
var myString = myURL.absoluteString

Here's another way to do it :) The concept is to create a clip-path polygon with the wave as one side.
This approach is fairly flexible. You can change the position (left, right, top or bottom) in which the wave appears, change the wave function to any function(t) which maps to [0,1]). The polygon can also be used for shape-outside, which lets text flow around the wave when in 'left' or 'right' orientation.
At the end, an example you can uncomment which demonstrates animating the wave.

I doubt it's going to get much simpler than that, I'm afraid. Just accept it and move on.
Pure speculation is that you're using a terminal that attempts to do word-wrapping rather than character-wrapping, and treats B
as a word character but #
as a non-word character. So when it reaches the end of a line and searches for a place to break the line, it sees a #
almost immediately and happily breaks there; whereas with the B
, it has to keep searching for longer, and may have more text to wrap (which may be expensive on some terminals, e.g., outputting backspaces, then outputting spaces to overwrite the letters being wrapped).
But that's pure speculation.

In theory, there's nothing preventing you from sending a request body in a GET
request. The HTTP protocol allows it, but have no defined semantics, so it's up to you to document what exactly is going to happen when a client sends a GET
payload. For instance, you have to define if parameters in a JSON body are equivalent to querystring parameters or something else entirely.
However, since there are no clearly defined semantics, you have no guarantee that implementations between your application and the client will respect it. A server or proxy might reject the whole request, or ignore the body, or anything else. The REST way to deal with broken implementations is to circumvent it in a way that's decoupled from your application, so I'd say you have two options that can be considered best practices.
The simple option is to use POST
instead of GET
as recommended by other answers. Since POST
is not standardized by HTTP, you'll have to document how exactly that's supposed to work.
Another option, which I prefer, is to implement your application assuming the GET
payload is never tampered with. Then, in case something has a broken implementation, you allow clients to override the HTTP method with the X-HTTP-Method-Override
, which is a popular convention for clients to emulate HTTP methods with POST
. So, if a client has a broken implementation, it can write the GET
request as a POST
, sending the X-HTTP-Method-Override: GET
method, and you can have a middleware that's decoupled from your application implementation and rewrites the method accordingly. This is the best option if you're a purist.

As Jose answered, screen -d -r
should do the trick. This is a combination of two commands, as taken from the man page.
screen -d
detaches the already-running screen session, and screen -r
reattaches the existing session. By running screen -d -r
, you force screen to detach it and then resume the session.
If you use the capital -D -RR
, I quote the man page because it's too good to pass up.
Attach here and now. Whatever that means, just do it.
Note: It is always a good idea to check the status of your sessions by means of "screen -list".

There is not a way to directly get the version out, but there are two work-arounds that could be done.
The version could be stored in a resource string, and placed into the manifest by:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.somepackage"
android:versionName="@string/version" android:versionCode="20">
One could create a custom view, and place it into the XML. The view would use this to assign the name:
context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version
or something like that.
Can also see here on how to turn on MSDTC from the Control Panel's services.msc.
On the server where the trigger resides, you need to turn the MSDTC service on. You can this by clicking START > SETTINGS > CONTROL PANEL > ADMINISTRATIVE TOOLS > SERVICES. Find the service called 'Distributed Transaction Coordinator' and RIGHT CLICK (on it and select) > Start.
You can use Random.nextInt(n). This returns a random int in [0,n). Just using max-min+1 in place of n and adding min to the answer will give a value in the desired range.

I have mixed feelings about the Cocotron project. I'm glad they are releasing source code and sharing but I don't feel that they are doing things the easiest way.
Examples.
Apple has released the source code to the objective-c runtime, which includes properties and garbage collection. The Cocotron project however has their own implementation of the objective-c runtime. Why bother to duplicate the effort? There is even a Visual Studio Project file that can be used to build an objc.dll file. Or if you're really lazy, you can just copy the DLL file from an installation of Safari on Windows.
They also did not bother to leverage CoreFoundation, which is also open sourced by Apple. I posted a question about this but did not receive an answer.
I think the current best solution is to take source code from multiple sources (Apple, CocoTron, GnuStep) and merge it together to what you need. You'll have to read a lot of source but it will be worth the end result.
$eval
and $parse
don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.
Q: What exactly is $eval doing? Why does it need its own mini parsing language?
From the docs:
Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.
It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).
Q: Why isn't plain old javascript "eval" being used?
Because it's not actually evaluating JavaScript. As the docs say:
If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.

I have already upvoted the @dasblinkenlight answer since the Median of Medians algorithm in fact solves this problem in O(n) time. I only want to add that this problem could be solved in O(n) time by using heaps also. Building a heap could be done in O(n) time by using the bottom-up. Take a look to the following article for a detailed explanation Heap sort
Supposing that your array has N elements, you have to build two heaps: A MaxHeap that contains the first N/2 elements (or (N/2)+1 if N is odd) and a MinHeap that contains the remaining elements. If N is odd then your median is the maximum element of MaxHeap (O(1) by getting the max). If N is even, then your median is (MaxHeap.max()+MinHeap.min())/2 this takes O(1) also. Thus, the real cost of the whole operation is the heaps building operation which is O(n).
BTW this MaxHeap/MinHeap algorithm works also when you don't know the number of the array elements beforehand (if you have to resolve the same problem for a stream of integers for e.g). You can see more details about how to resolve this problem in the following article Median Of integer streams

The Path class is very useful here.
You get two methods called
that could solve your issue
So for example you could write: (if you don't mind the exact file name)
using(StreamWriter sw = new StreamWriter(Path.GetTempFileName()))
{
sw.WriteLine("Your error message");
}
Or if you need to set your file name
string myTempFile = Path.Combine(Path.GetTempPath(), "SaveFile.txt");
using(StreamWriter sw = new StreamWriter(myTempFile))
{
sw.WriteLine("Your error message");
}
Simply type the table name and select it and press ATL + F1
Say your table name is Customer
then open a new query window, type and select the table name and press ALT + F1
It will show the complete definition of table.
This is not a system font. this font is not supported in other systems. you can use font-face, convert font from this Site or from this
In answer to your first question, there's no parameter substitution because you've put the delimiter in quotes - the bash manual says:
The format of here-documents is:
<<[-]word here-document delimiter
No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. [...]
If you change your first example to use <<EOF
instead of << "EOF"
you'll find that it works.
In your second example, the shell invokes sudo
only with the parameter cat
, and the redirection applies to the output of sudo cat
as the original user. It'll work if you try:
sudo sh -c "cat > /path/to/outfile" <<EOT

Your newly packaged library is not backward binary compatible (BC) with old version. For this reason some of the library clients that are not recompiled may throw the exception.
This is a complete list of changes in Java library API that may cause clients built with an old version of the library to throw java.lang.IncompatibleClassChangeError if they run on a new one (i.e. breaking BC):
Note: There are many other exceptions caused by other incompatible changes: NoSuchFieldError, NoSuchMethodError, IllegalAccessError, InstantiationError, VerifyError, NoClassDefFoundError and AbstractMethodError.
The better paper about BC is "Evolving Java-based APIs 2: Achieving API Binary Compatibility" written by Jim des Rivières.
There are also some automatic tools to detect such changes:
Usage of japi-compliance-checker for your library:
japi-compliance-checker OLD.jar NEW.jar
Usage of clirr tool:
java -jar clirr-core-0.6-uber.jar -o OLD.jar -n NEW.jar
Good luck!
You need to add C:\xampp\php

If you generally use constructor-injection and don't want to switch to property-injection then Spring's lookup-method-injection will let one bean lazily lookup the other and hence workaround the cyclic dependency. See here: http://docs.spring.io/spring/docs/1.2.9/reference/beans.html#d0e1161
The issue is that the value for backgroundImage
needs to be a string like this:
<div class="circular" v-bind:style="{ backgroundImage: 'url(' + image + ')' }"></div>
Here's a simplified fiddle that's working: https://jsfiddle.net/89af0se9/1/
Re: the comment below about kebab-case, this is how you can do that:
<div class="circular" v-bind:style="{ 'background-image': 'url(' + image + ')' }"></div>
In other words, the value for v-bind:style
is just a plain Javascript object and follows the same rules.
UPDATE: One other note about why you may have trouble getting this to work.
You should make sure your image
value is quoted so that the end resulting string is:
url('some/url/path/to/image.jpeg')
Otherwise, if your image URL has special characters in it (such as whitespace or parentheses) the browser may not apply it properly. In Javascript, the assignment would look like:
this.image = "'some/url/path/to/image.jpeg'"
or
this.image = "'" + myUrl + "'"
Technically, this could be done in the template, but the escaping required to keep it valid HTML isn't worth it.
More info here: Is quoting the value of url() really necessary?
Try this
String[] arr = list.toArray(new String[list.size()]);
You can take both the collections in two different lists, say list1 and list2.
Then just write
list1.RemoveAll(Item => list2.Contains(Item));
This will work.
You can call the method getBoundingClientRect()
on a reference to the element. Then you can examine the top
, left
, right
and/or bottom
properties...
var offsets = document.getElementById('11a').getBoundingClientRect();
var top = offsets.top;
var left = offsets.left;
If using jQuery, you can use the more succinct code...
var offsets = $('#11a').offset();
var top = offsets.top;
var left = offsets.left;

You shouldn't get both horizontal and vertical scrollbars unless you make the content large enough to require them.
However you typically do in IE due to a bug. Check in other browsers (Firefox etc.) to find out whether it is in fact only IE that is doing it.
IE6-7 (amongst other browsers) supports the proposed CSS3 extension to set scrollbars independently, which you could use to suppress the vertical scrollbar:
overflow: auto;
overflow-y: hidden;
You may also need to add for IE8:
-ms-overflow-y: hidden;
as Microsoft are threatening to move all pre-CR-standard properties into their own ‘-ms’ box in IE8 Standards Mode. (This would have made sense if they'd always done it that way, but is rather an inconvenience for everyone now.)
On the other hand it's entirely possible IE8 will have fixed the bug anyway.
You don't need to specify both at the same time, unless you're specifically restricting the other verbs (i.e. you don't want PUT or DELETE, etc).
Contrary to some of the comments, I was also unable to use both Attributes [HttpGet, HttpPost]
at the same time, but was able to specify both verbs instead.

{
return Json(new {
// user input
input = id,
// just so there's different content in the response
when = DateTime.Now,
// type of request
req = this.Request.HttpMethod,
// differentiate calls in response, for matching up
call = new StackTrace().GetFrame(1).GetMethod().Name
},
JsonRequestBehavior.AllowGet);

For those of you using Centos (and perhaps other linux distibutions), you need to make sure that its FW (iptables) allows for port 80 or any other port you want.
See here on how to completely disable it (for testing purposes only!). And here for specific rules

You can see it implemented here : Sql Fiddle Demo. Exactly what you need.
Update Splitting in two steps. First we get a table having all values(comma separated) against a unique[Name,id]. Then from obtained table we get all names and values as a single value against each unique id See this explained here SQL Fiddle Demo (scroll down as it has two result sets)
Edit There was a mistake in reading question, I had grouped only by id. But two group_contacts are needed if (Values are to be concatenated grouped by Name and id and then over all by id). Previous answer was
select
id,group_concat(concat(`name`,':',`value`) separator ',')
as Result from mytbl group by id

Try this:
private byte[] Hex2Bin(string hex)
{
if ((hex == null) || (hex.Length < 1)) {
return new byte[0];
}
int num = hex.Length / 2;
byte[] buffer = new byte[num];
num *= 2;
for (int i = 0; i < num; i++) {
int num3 = int.Parse(hex.Substring(i, 2), NumberStyles.HexNumber);
buffer[i / 2] = (byte) num3;
i++;
}
return buffer;
}
private string Bin2Hex(byte[] binary)
{
StringBuilder builder = new StringBuilder();
foreach(byte num in binary) {
if (num > 15) {
builder.AppendFormat("{0:X}", num);
} else {
builder.AppendFormat("0{0:X}", num); /////// ?? 15 ???? 0
}
}
return builder.ToString();
}
Finally, I got a solution!

Use the following code it worked for me:
# Create the figure
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
# Generate the values
x_vals = X_iso[:, 0:1]
y_vals = X_iso[:, 1:2]
z_vals = X_iso[:, 2:3]
# Plot the values
ax.scatter(x_vals, y_vals, z_vals, c = 'b', marker='o')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')
plt.show()
while X_iso is my 3-D array and for X_vals, Y_vals, Z_vals I copied/used 1 column/axis from that array and assigned to those variables/arrays respectively.
Use Bash and the date command to convert from an ISO-like format to the one you want. I wanted an org-mode date format (and list item), so I did this:
echo + [$(date -d "$(git log --pretty=format:%ai -1)" +"%Y-%m-%d %a %H:%M")] \
$(git log --pretty=format:"%h %s" --abbrev=12 -1)
And the result is for example:

Still a huge pain. Poor UI design (But my mindset does not seem to match the mindset of software engineers that make 100+ character variable and method names. Enough of my complaining)
I'll modify a previous post for the current version.
In the source editor box there is a list of types of text that you may set the font for: Plain text Comments Documentation Comments . . .
Select any or all items from the source editor list and the name and size of the font for that particular text will show up in the 'Font' window below the 'Source Editor' window. (If you happen to skip highlighting one of these, you will be able to get to the Font Inspector and select new sizes, but will wonder why the changes you make are not being applied!)
Congratulations. Your may now read your code. Wasn't that painless?
JS ist browser-based, PHP is server-based. You have to generate some browser-based request/signal to get the data from the JS into the PHP. Take a look into Ajax.
This will give you the difference between two dates, in milliseconds
var diff = Math.abs(date1 - date2);
In your example, it'd be
var diff = Math.abs(new Date() - compareDate);
You need to make sure that compareDate
is a valid Date
object.
Something like this will probably work for you
var diff = Math.abs(new Date() - new Date(dateStr.replace(/-/g,'/')));
i.e. turning "2011-02-07 15:13:06"
into new Date('2011/02/07 15:13:06')
, which is a format the Date
constructor can comprehend.

So many answers and still everybody forgot about the strangely named, oddly behaved, and yet still handy dict.setdefault()
This
value = my_dict.setdefault(key, default)
basically just does this:
try:
value = my_dict[key]
except KeyError: # key not found
value = my_dict[key] = default
e.g.
>>> mydict = {'a':1, 'b':2, 'c':3}
>>> mydict.setdefault('d', 4)
4 # returns new value at mydict['d']
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # a new key/value pair was indeed added
# but see what happens when trying it on an existing key...
>>> mydict.setdefault('a', 111)
1 # old value was returned
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # existing key was ignored
You can do it with cut
:
cut -d " " -f 3- input_filename > output_filename
Explanation:
cut
: invoke the cut command-d " "
: use a single space as the delimiter (cut
uses TAB by default)-f
: specify fields to keep3-
: all the fields starting with field 3input_filename
: use this file as the input> output_filename
: write the output to this file.Alternatively, you can do it with awk
:
awk '{$1=""; $2=""; sub(" ", " "); print}' input_filename > output_filename
Explanation:
awk
: invoke the awk command$1=""; $2="";
: set field 1 and 2 to the empty stringsub(...);
: clean up the output fields because fields 1 & 2 will still be delimited by " "print
: print the modified lineinput_filename > output_filename

FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :
strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"
If you are using the following Windows versions or later: Windows Server 2012, Windows Server 2012 R2, or Windows 8.1 then MakeCert is now deprecated, and Microsoft recommends using the PowerShell Cmdlet New-SelfSignedCertificate.
If you're using an older version such as Windows 7, you'll need to stick with MakeCert or another solution. Some people suggest the Public Key Infrastructure Powershell (PSPKI) Module.
While you can create a self-signed code-signing certificate (SPC - Software Publisher Certificate) in one go, I prefer to do the following:
makecert -r -pe -n "CN=My CA" -ss CA -sr CurrentUser ^
-a sha256 -cy authority -sky signature -sv MyCA.pvk MyCA.cer
(^ = allow batch command-line to wrap line)
This creates a self-signed (-r) certificate, with an exportable private key (-pe). It's named "My CA", and should be put in the CA store for the current user. We're using the SHA-256 algorithm. The key is meant for signing (-sky).
The private key should be stored in the MyCA.pvk file, and the certificate in the MyCA.cer file.
Because there's no point in having a CA certificate if you don't trust it, you'll need to import it into the Windows certificate store. You can use the Certificates MMC snapin, but from the command line:
certutil -user -addstore Root MyCA.cer
makecert -pe -n "CN=My SPC" -a sha256 -cy end ^
-sky signature ^
-ic MyCA.cer -iv MyCA.pvk ^
-sv MySPC.pvk MySPC.cer
It is pretty much the same as above, but we're providing an issuer key and certificate (the -ic and -iv switches).
We'll also want to convert the certificate and key into a PFX file:
pvk2pfx -pvk MySPC.pvk -spc MySPC.cer -pfx MySPC.pfx
If you want to protect the PFX file, add the -po switch, otherwise PVK2PFX creates a PFX file with no passphrase.
signtool sign /v /f MySPC.pfx ^
/t http://timestamp.url MyExecutable.exe
(See why timestamps may matter)
If you import the PFX file into the certificate store (you can use PVKIMPRT or the MMC snapin), you can sign code as follows:
signtool sign /v /n "Me" /s SPC ^
/t http://timestamp.url MyExecutable.exe
Some possible timestamp URLs for signtool /t
are:
http://timestamp.verisign.com/scripts/timstamp.dll
http://timestamp.globalsign.com/scripts/timstamp.dll
http://timestamp.comodoca.com/authenticode
For those who are not .NET developers, you will need a copy of the Windows SDK and .NET framework. A current link is available here: SDK & .NET (which installs makecert in C:\Program Files\Microsoft SDKs\Windows\v7.1
). Your mileage may vary.
MakeCert is available from the Visual Studio Command Prompt. Visual Studio 2015 does have it, and it can be launched from the Start Menu in Windows 7 under "Developer Command Prompt for VS 2015" or "VS2015 x64 Native Tools Command Prompt" (probably all of them in the same folder).
