Expires
and Cache-Control
are "strong caching headers"
Last-Modified
and ETag
are "weak caching headers"
First the browser check Expires/Cache-Control
to determine whether or not to make a request to the server
If have to make a request, it will send Last-Modified/ETag
in the HTTP request. If the Etag
value of the document matches that, the server will send a 304 code instead of 200, and no content. The browser will load the contents from its cache.
Exact transfer to Angular2+ is as below:
<button (click)="myFunc()"></button>
also in your component file:
import { Component, OnInit } from "@angular/core";
@Component({
templateUrl:"button.html" //this is the component which has the above button html
})
export class App implements OnInit{
constructor(){}
ngOnInit(){
}
myFunc(){
console.log("function called");
}
}
WhiteStarUML is a fork of StarUML that is still maintain http://sourceforge.net/projects/whitestaruml/?source=dlp.
I faced multiple time the same issue that I add device info to portal so I can publish build to fabric testing but device is still missing due to how Xcode is not updating team provisioning profile.
So based on other answers and my own experience, the best and quickest way is to remove all Provisioning profiles manually by command line while automatic signing will download them again with updated devices.
If this can lead to some unknown issues I don't know and highly doubt, but it works for me just fine.
So just:
cd ~/Library/MobileDevice/Provisioning\ Profiles/
rm *
And try again...
You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.
SELECT * FROM <table_name> WHERE id = 1
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';
If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':
hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')
You can use localStorage
for the purpose.
Steps:
<input type='text' minlength=3 /><br />
if browser supports html5,
it will automatical be validate attributes(minlength) in tag
but Safari(iOS) doesn't working
onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"
Change 1000 to the number of milliseconds you want to delay.
For php7.0-fpm I call:
service php7.0-fpm status
php7.0-fpm start/running, process 25993
Now watch for the good part. The process name is actually php-fpm7.0
echo `/bin/pidof php-fpm7.0`
26334 26297 26286 26285 26282
You can do as
body{
background:url('equote.png'),url('equote.png');
background-size:400px 100px,50px 50px;
}
You can use this script:
*! > input[type=text] { background: #000; }
This will select any parent of a text input. But wait, there's still much more. If you want, you can select a specified parent:
.input-wrap! > input[type=text] { background: #000; }
Or select it when it's active:
.input-wrap! > input[type=text]:focus { background: #000; }
Check out this HTML:
<div class="input-wrap">
<input type="text" class="Name"/>
<span class="help hide">Your name sir</span>
</div>
You can select that span.help
when the input
is active and show it:
.input-wrap! .help > input[type=text]:focus { display: block; }
There are many more capabilities; just check out the documentation of the plugin.
BTW, it works in Internet Explorer.
Given that today (was not available when this question was made) lots of people use Jupyter Notebook as python console, there is an extremely easy way to save the plots as .png
, just call the matplotlib
's pylab
class from Jupyter Notebook, plot the figure 'inline' jupyter cells, and then drag that figure/image to a local directory. Don't forget
%matplotlib inline
in the first line!
All your problems derive from this
byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;
Which are enclosed in a try, catch block, the problem is that in case the program found an exception you are not returning anything. Put it like this (modify it as your program logic stands):
public static byte[] encrypt(String toEncrypt) throws Exception{
try{
String plaintext = toEncrypt;
String key = "01234567890abcde";
String iv = "fedcba9876543210";
SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());
Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;
} catch(Exception e){
return null; // Always must return something
}
}
For the second one you must catch the Exception from the encrypt method call, like this (also modify it as your program logic stands):
public void actionPerformed(ActionEvent e)
.
.
.
try {
byte[] encrypted = encrypt(concatURL);
String encryptedString = bytesToHex(encrypted);
content.removeAll();
content.add(new JLabel("Concatenated User Input -->" + concatURL));
content.add(encryptedTextField);
setContentPane(content);
} catch (Exception exc) {
// TODO: handle exception
}
}
The lessons you must learn from this:
It's better not to use refs in such cases. Use:
<input
type="checkbox"
checked={this.state.active}
onClick={this.handleClick}
/>
There are some options:
checked
vs defaultChecked
The former would respond to both state changes and clicks. The latter would ignore state changes.
onClick
vs onChange
The former would always trigger on clicks.
The latter would not trigger on clicks if checked
attribute is present on input
element.
I did it like this
func showAlert() {
let alert = UIAlertController(title: "Thanks!", message: "We'll get back to you as soon as posible.", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
self.dismissView()
}))
self.present(alert, animated: true)
}
func dismissView() {
navigationController?.popViewController(animated: true)
dismiss(animated: true, completion: nil)
}
This may work
CREATE USER 'user'@'localhost' IDENTIFIED BY 'pwd';
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
Yes you can. You can even test it:
var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
console.log(++i);_x000D_
if (i === 5) clearInterval(timer);_x000D_
console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);
_x000D_
In this example, this timer clears when i
reaches 5.
Use this
os.chdir('C:/Users\expoperialed\Desktop\Python')
CREATE DATABASE hindi_test
CHARACTER SET utf8
COLLATE utf8_unicode_ci;
USE hindi_test;
CREATE TABLE `hindi` (`data` varchar(200) COLLATE utf8_unicode_ci NOT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
INSERT INTO `hindi` (`data`) VALUES('????????');
In short:
getPath()
gets the path string that the File
object was constructed with, and it may be relative current directory.getAbsolutePath()
gets the path string after resolving it against the current directory if it's relative, resulting in a fully qualified path.getCanonicalPath()
gets the path string after resolving any relative path against current directory, and removes any relative pathing (.
and ..
), and any file system links to return a path which the file system considers the canonical means to reference the file system object to which it points.Also, each of these has a File equivalent which returns the corresponding File
object.
Note that IMO, Java got the implementation of an "absolute" path wrong; it really should remove any relative path elements in an absolute path. The canonical form would then remove any FS links or junctions in the path.
It means that there have been other commits pushed to the remote repository that differ from your commits. You can usually solve this with a
git pull
before you push
Ultimately, "fast-forward" means that the commits can be applied directly on top of the working tree without requiring a merge.
@William Brendel answer provided three different use cases in nice way.
Use case 1:
Offical java documentation page on this provides same use-cases.
Within an instance method or a constructor, this is a reference to the current object — the object whose method or constructor is being called. You can refer to any member of the current object from within an instance method or a constructor by using this.
It covers two examples :
Using this with a Field and Using this with a Constructor
Use case 2:
Other use case which has not been quoted in this post: this
can be used to synchronize the current object in a multi-threaded application to guard critical section of data & methods.
synchronized(this){
// Do some thing.
}
Use case 3:
Implementation of Builder pattern depends on use of this
to return the modified object.
Refer to this post
With "Asset Type" set to "Image", try setting the same image for the foreground and background layers, keeping the same "Resize" percentage.
INSERT INTO TABLE_NAME (TIMESTAMP_VALUE) VALUES (TO_TIMESTAMP('2014-07-02 06:14:00.742000000', 'YYYY-MM-DD HH24:MI:SS.FF'));
Recently I was playing with this method too. I wrote a memoized algorithm to calcualte Fibonacci numbers which could serve as another illustration on how to use the method.
We can start by defining a map and putting the values in it for the base cases, namely, fibonnaci(0)
and fibonacci(1)
:
private static Map<Integer,Long> memo = new HashMap<>();
static {
memo.put(0,0L); //fibonacci(0)
memo.put(1,1L); //fibonacci(1)
}
And for the inductive step all we have to do is redefine our Fibonacci function as follows:
public static long fibonacci(int x) {
return memo.computeIfAbsent(x, n -> fibonacci(n-2) + fibonacci(n-1));
}
As you can see, the method computeIfAbsent
will use the provided lambda expression to calculate the Fibonacci number when the number is not present in the map. This represents a significant improvement over the traditional, tree recursive algorithm.
I hope i am understanding your question correctly, as the above comment says you need to provide more information.
In order to bind it to your view you would use property binding which is using [property]="value". Hope this helps.

You can use GCHandleType.Weak instead of Pinned. On the other hand, there is another way to get a pointer to an object:
object o = new object();
TypedReference tr = __makeref(o);
IntPtr ptr = **(IntPtr**)(&tr);
Requires unsafe block and is very, very dangerous and should not be used at all. ?
Back in the day when by-ref locals weren't possible in C#, there was one undocumented mechanism that could accomplish a similar thing – __makeref
.
object o = new object();
ref object r = ref o;
//roughly equivalent to
TypedReference tr = __makeref(o);
There is one important difference in that TypedReference is "generic"; it can be used to store a reference to a variable of any type. Accessing such a reference requires to specify its type, e.g. __refvalue(tr, object)
, and if it doesn't match, an exception is thrown.
To implement the type checking, TypedReference must have two fields, one with the actual address to the variable, and one with a pointer to its type representation. It just so happens that the address is the first field.
Therefore, __makeref
is used first to obtain a reference to the variable o
. The cast (IntPtr**)(&tr)
treats the structure as an array (represented via a pointer) of IntPtr*
(pointers to a generic pointer type), accessed via a pointer to it. The pointer is first dereferenced to obtain the first field, then the pointer there is dereferenced again to obtain the value actually stored in the variable o
– the pointer to the object itself.
However, since 2012, I have come up with a better and safer solution:
public static class ReferenceHelpers
{
public static readonly Action<object, Action<IntPtr>> GetPinnedPtr;
static ReferenceHelpers()
{
var dyn = new DynamicMethod("GetPinnedPtr", typeof(void), new[] { typeof(object), typeof(Action<IntPtr>) }, typeof(ReferenceHelpers).Module);
var il = dyn.GetILGenerator();
il.DeclareLocal(typeof(object), true);
il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Stloc_0);
il.Emit(OpCodes.Ldarg_1);
il.Emit(OpCodes.Ldloc_0);
il.Emit(OpCodes.Conv_I);
il.Emit(OpCodes.Call, typeof(Action<IntPtr>).GetMethod("Invoke"));
il.Emit(OpCodes.Ret);
GetPinnedPtr = (Action<object, Action<IntPtr>>)dyn.CreateDelegate(typeof(Action<object, Action<IntPtr>>));
}
}
This creates a dynamic method that first pins the object (so its storage doesn't move in the managed heap), then executes a delegate that receives its address. During the execution of the delegate, the object is still pinned and thus safe to be manipulated via the pointer:
object o = new object();
ReferenceHelpers.GetPinnedPtr(o, ptr => Console.WriteLine(Marshal.ReadIntPtr(ptr) == typeof(object).TypeHandle.Value)); //the first pointer in the managed object header in .NET points to its run-time type info
This is the easiest way to pin an object, since GCHandle requires the type to be blittable in order to pin it. It has the advantage of not using implementation details, undocumented keywords and memory hacking.
All string functions as lower
, upper
, strip
are returning a string without modifying the original. If you try to modify a string, as you might think well it is an iterable
, it will fail.
x = 'hello'
x[0] = 'i' #'str' object does not support item assignment
There is a good reading about the importance of strings being immutable: Why are Python strings immutable? Best practices for using them

There is no way to reliably check if "dotted module" is importable without importing its parent package. Saying this, there are many solutions to problem "how to check if Python module exists".
Below solution address the problem that imported module can raise ImportError even it exists. We want to distinguish that situation from such in which module does not exist.
Python 2:
import importlib
import pkgutil
import sys
def find_module(full_module_name):
"""
Returns module object if module `full_module_name` can be imported.
Returns None if module does not exist.
Exception is raised if (existing) module raises exception during its import.
"""
module = sys.modules.get(full_module_name)
if module is None:
module_path_tail = full_module_name.split('.')
module_path_head = []
loader = True
while module_path_tail and loader:
module_path_head.append(module_path_tail.pop(0))
module_name = ".".join(module_path_head)
loader = bool(pkgutil.find_loader(module_name))
if not loader:
# Double check if module realy does not exist
# (case: full_module_name == 'paste.deploy')
try:
importlib.import_module(module_name)
except ImportError:
pass
else:
loader = True
if loader:
module = importlib.import_module(full_module_name)
return module
Python 3:
import importlib
def find_module(full_module_name):
"""
Returns module object if module `full_module_name` can be imported.
Returns None if module does not exist.
Exception is raised if (existing) module raises exception during its import.
"""
try:
return importlib.import_module(full_module_name)
except ImportError as exc:
if not (full_module_name + '.').startswith(exc.name + '.'):
raise
The easiest option is to just use the list() command. However, if you don't want to use it or it dose not work for some bazaar reason, you can always use this method.

Setting the image using picture.ImageLocation()
works fine, but you are using a relative path. Check your path against the location of the .exe
after it is built.
For example, if your .exe
is located at:
<project folder>/bin/Debug/app.exe
The image would have to be at:
<project folder>/bin/Image/1.jpg
Of course, you could just set the image at design-time (the Image
property on the PictureBox
property sheet).
If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image
. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory
to Copy if newer
.
At this point the image file will be copied when you build the application and you can use
picture.ImageLocation = @"Image\1.jpg";
In my case whitespaces at the end of the lines of .gitignore was the cause. So watch out for whitespaces in the .gitignore!
The error is in your string formatting.
The correct way to use traditional string formatting using the '%' operator is to use a printf-style format string (Python documentation for this here: http://docs.python.org/2/library/string.html#format-string-syntax):
"'%s' is longer than '%s'" % (name1, name2)
However, the '%' operator will probably be deprecated in the future. The new PEP 3101 way of doing things is like this:
"'{0}' is longer than '{1}'".format(name1, name2)
I think for your situation, the easy and simple for your html input , you can probably add the attribute title

Create the following function
CREATE OR REPLACE FUNCTION isnull(text, text) RETURNS text AS 'SELECT (CASE (SELECT $1 "
"is null) WHEN true THEN $2 ELSE $1 END) AS RESULT' LANGUAGE 'sql'
And it'll work.
You may to create different versions with different parameter types.
You can get the comments of a particular method by using the ReflectionMethod class and calling ->getDocComment().
http://www.php.net/manual/en/reflectionclass.getdoccomment.php
You can achieve this by using the following query:
EXEC sp_msforeachdb
'IF EXISTS
(
SELECT 1
FROM [?].sys.objects
WHERE name LIKE ''OBJECT_TO_SEARCH''
)
SELECT
''?'' AS DB,
name AS Name,
type_desc AS Type
FROM [?].sys.objects
WHERE name LIKE ''OBJECT_TO_SEARCH'''
Just replace OBJECT_TO_SEARCH with the actual object name you are interested in (or part of it, surrounded with %).

I found a generic and simple way to do that. In my class I created a method that returns the generic type according to it's position in the class definition. Let's assume a class definition like this:
public class MyClass<A, B, C> {
}
Now let's create some attributes to persist the types:
public class MyClass<A, B, C> {
private Class<A> aType;
private Class<B> bType;
private Class<C> cType;
// Getters and setters (not necessary if you are going to use them internally)
}
Then you can create a generic method that returns the type based on the index of the generic definition:
/**
* Returns a {@link Type} object to identify generic types
* @return type
*/
private Type getGenericClassType(int index) {
// To make it use generics without supplying the class type
Type type = getClass().getGenericSuperclass();
while (!(type instanceof ParameterizedType)) {
if (type instanceof ParameterizedType) {
type = ((Class<?>) ((ParameterizedType) type).getRawType()).getGenericSuperclass();
} else {
type = ((Class<?>) type).getGenericSuperclass();
}
}
return ((ParameterizedType) type).getActualTypeArguments()[index];
}
Finally, in the constructor just call the method and send the index for each type. The complete code should look like:
public class MyClass<A, B, C> {
private Class<A> aType;
private Class<B> bType;
private Class<C> cType;
public MyClass() {
this.aType = (Class<A>) getGenericClassType(0);
this.bType = (Class<B>) getGenericClassType(1);
this.cType = (Class<C>) getGenericClassType(2);
}
/**
* Returns a {@link Type} object to identify generic types
* @return type
*/
private Type getGenericClassType(int index) {
Type type = getClass().getGenericSuperclass();
while (!(type instanceof ParameterizedType)) {
if (type instanceof ParameterizedType) {
type = ((Class<?>) ((ParameterizedType) type).getRawType()).getGenericSuperclass();
} else {
type = ((Class<?>) type).getGenericSuperclass();
}
}
return ((ParameterizedType) type).getActualTypeArguments()[index];
}
}
Hazar is right with his \t
. Here's the full list of escape characters for C#:
\'
for a single quote.
\"
for a double quote.
\\
for a backslash.
\0
for a null character.
\a
for an alert character.
\b
for a backspace.
\f
for a form feed.
\n
for a new line.
\r
for a carriage return.
\t
for a horizontal tab.
\v
for a vertical tab.
\uxxxx
for a unicode character hex value (e.g. \u0020
).
\x
is the same as \u
, but you don't need leading zeroes (e.g. \x20
).
\Uxxxxxxxx
for a unicode character hex value (longer form needed for generating surrogates).
$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){

Get-content Filename returns an array of strings for each line.
On the first string only, I split it based on ",". Dumping it into $IP_Array.
$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
if ($IP -eq "2.2.2.2") {

const iframe = '<iframe height="265" style="width: 100%;" scrolling="no" title="fx." src="//codepen.io/ycw/embed/JqwbQw/?height=265&theme-id=0&default-tab=js,result" frameborder="no" allowtransparency="true" allowfullscreen="true">See the Pen <a href="https://codepen.io/ycw/pen/JqwbQw/">fx.</a> by ycw(<a href="https://codepen.io/ycw">@ycw</a>) on <a href="https://codepen.io">CodePen</a>.</iframe>';
A function component to load Iframe
function Iframe(props) {
return (<div dangerouslySetInnerHTML={ {__html: props.iframe?props.iframe:""}} />);
}
Usage:
import React from "react";
import ReactDOM from "react-dom";
function App() {
return (
<div className="App">
<h1>Iframe Demo</h1>
<Iframe iframe={iframe} />,
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
Edit on CodeSandbox:
You can disable the app using enable maintenance mode from the admin panel.
Without mod_expires it will be harder to set expiration headers on your files. For anything generated you can certainly set some default headers on the answer, doing the job of mod_expires like that:
<?php header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T', time() + 3600)); ?>
(taken from: Stack Overflow answer from @brianegge, where the mod_expires solution is also explained)
Now this won't work for static files, like your javascript files. As for static files there is only apache (without any expiration module) between the browser and the source file.
To prevent caching of javascript files, which is done on your browser, you can use a random token at the end of the js url, something like ?rd=45642111
, so the url looks like:
<script type="texte/javascript" src="my/url/myjs.js?rd=4221159546">
If this url on the page is generated by a PHP file you can simply add the random part with PHP. This way of randomizing url by simply appending random query string parameters is the base thing upôn no-cache setting of ajax jQuery request for example. The browser will never consider 2 url having different query strings to be the same, and will never use the cached version.
EDIT
Note that you should alos test mod_headers. If you have mod_headers you can maybe set the Expires headers directly with the Header keyword.
read = com.ExecuteReader()
SqlDataReader
has a function Read()
that reads the next row from your query's results and returns a bool
whether it found a next row to read or not. So you need to check that before you actually get the columns from your reader (which always just gets the current row that Read()
got). Or preferably make a loop while(read.Read())
if your query returns multiple rows.
Actually this can be done without creating a temporary file. The method described by jeb and dbenham will work even with a target file that contains no backspaces. The critical point is that the line recognized by findstr.exe must not end with a CRLF. So the obvious text file to scan with a line not ending with a CRLF is the invoking batch itself, provided that we end it with such a line! Here's an updated example script working this way...
Changes from the previous example:
@echo off
setlocal
call :Echo.Color.Init
goto main
:Echo.Color %1=Color %2=Str [%3=/n]
setlocal enableDelayedExpansion
set "str=%~2"
:Echo.Color.2
:# Replace path separators in the string, so that the final path still refers to the current path.
set "str=a%ECHO.DEL%!str:\=a%ECHO.DEL%\..\%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%!"
set "str=!str:/=a%ECHO.DEL%/..\%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%!"
set "str=!str:"=\"!"
:# Go to the script directory and search for the trailing -
pushd "%ECHO.DIR%"
findstr /p /r /a:%~1 "^^-" "!str!\..\!ECHO.FILE!" nul
popd
:# Remove the name of this script from the output. (Dependant on its length.)
for /l %%n in (1,1,12) do if not "!ECHO.FILE:~%%n!"=="" <nul set /p "=%ECHO.DEL%"
:# Remove the other unwanted characters "\..\: -"
<nul set /p "=%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%%ECHO.DEL%"
:# Append the optional CRLF
if not "%~3"=="" echo.
endlocal & goto :eof
:Echo.Color.Var %1=Color %2=StrVar [%3=/n]
if not defined %~2 goto :eof
setlocal enableDelayedExpansion
set "str=!%~2!"
goto :Echo.Color.2

set "ECHO.COLOR=call :Echo.Color"
set "ECHO.DIR=%~dp0"
set "ECHO.FILE=%~nx0"
set "ECHO.FULL=%ECHO.DIR%%ECHO.FILE%"
:# Use prompt to store a backspace into a variable. (Actually backspace+space+backspace)

exit /b
:# The following line must be last and not end by a CRLF.

PS. I'm having a problem with the output of the ! character that you did not have in the previous example. (Or at least you did not have the same symptoms.) To be investigated.
You should also check /var/db/receipts and remove all entries that contain com.mysql.*
Using sudo rm -rf /var/db/receipts/com.mysql.* didn't work for me. I had to go into var/db/receipts and delete each one seperately.
Take out the method name from in your import statement. e.g.
import Dan.Vik.disp;
becomes:
import Dan.Vik;
I need to do this and have the <dt>
content vertically centered, relative to the <dd>
content. I used display: inline-block
, together with vertical-align: middle
See full example on Codepen here
.dl-horizontal {
font-size: 0;
text-align: center;
dt, dd {
font-size: 16px;
display: inline-block;
vertical-align: middle;
width: calc(50% - 10px);
}
dt {
text-align: right;
padding-right: 10px;
}
dd {
font-size: 18px;
text-align: left;
padding-left: 10px;
}
}
The two most usual choices are GTK+, which has documentation links here, and is mostly used with C; or Qt which has documentation here and is more used with C++.
I posted these two as you do not specify an operating system and these two are pretty cross-platform.
This is documented in section 3.9.3 of the Spring 3.0 manual:
For a fallback match, the bean name is considered a default qualifier value.
In other words, the default behaviour is as though you'd added @Qualifier("country")
to the setter method.
You can do it in the following way: So you will not only format the number but you can also pass as a parameter how many decimal digits to display, you set a custom decimal and mile separator.
function format(number, decimals = 2, decimalSeparator = '.', thousandsSeparator = ',') {
const roundedNumber = number.toFixed(decimals);
let integerPart = '', fractionalPart = '';
if (decimals == 0) {
integerPart = roundedNumber;
decimalSeparator = '';
} else {
let numberParts = roundedNumber.split('.');
integerPart = numberParts[0];
fractionalPart = numberParts[1];
}
integerPart = integerPart.replace(/(\d)(?=(\d{3})+(?!\d))/g, `$1${thousandsSeparator}`);
return `${integerPart}${decimalSeparator}${fractionalPart}`;
}
Use:
let min = 1556454.0001;
let max = 15556982.9999;
console.time('number format');
for (let i = 0; i < 15000; i++) {
let randomNumber = Math.random() * (max - min) + min;
let formated = format(randomNumber, 4, ',', '.'); // formated number
console.debug('number: ', randomNumber, 'formated: ', formated);
}
console.timeEnd('number format');
This would truncate the file:
$fh = fopen( 'filelist.txt', 'w' );
fclose($fh);
In clear.php, redirect to the caller page by making use of $_SERVER['HTTP_REFERER']
value.
I think that you would install Android SDK files not in (your PC)\Appdata\Local\Android\sdk (default Path). Also there was nothing when you double click 'intelhaxm-android.exe' file.
If it was, Browse (your PC)\Appdata\Local\Temp\intel\HAXM\6.0.3(yyyy-mm-dd_hh_mm_ss) (or silent), then you must see 'hax64' (or hax) file, and simply invoke this file.
Through
remove_column :table_name, :column_name
in a migration file
You can remove a column directly in a rails console by typing:
ActiveRecord::Base.remove_column :table_name, :column_name
You can also use the built-in sp_who2
stored procedure to get current blocked and blocking processes on a SQL Server instance. Typically you'd run this alongside a SQL Profiler instance to find a blocking process and look at the most recent command that spid issued in profiler.
If you do not specifically need the alt text of an image, then you can just target the class/id of the image.
$('img.propImg').each(function(){
enter code here
}
I know it’s not quite answering the question, though I’d spent ages trying to figure this out and this question gave me the solution :). In my case I needed to hide any image tags with a specific src.
$('img.propImg').each(function(){ //for each loop that gets all the images.
if($(this).attr('src') == "img/{{images}}") { // if the src matches this
$(this).css("display", "none") // hide the image.
}
});
Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.
So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.
Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.
var joinedString= string.Join(";", myDict.Select(x => x.Key + "=" + x.Value));
This question makes me nervous. It indicates that maybe you don't understand how using server-side code will impact you're page's DOM state.
Whenever you run server-side code the entire page is rebuilt from scratch. This has several implications:
If you can get away with it, you might want to push this down to javascript and avoid the postback. Perhaps use an XmlHttpRequest() call to trigger any server-side action you need.
There are many problems in your query.
This is a modified version of your code
string connetionString = null;
string sql = null;
// All the info required to reach your db. See connectionstrings.com
connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;
// Prepare a proper parameterized query
sql = "insert into Main ([Firt Name], [Last Name]) values(@first,@last)";
// Create the connection (and be sure to dispose it at the end)
using(SqlConnection cnn = new SqlConnection(connetionString))
{
try
{
// Open the connection to the database.
// This is the first critical step in the process.
// If we cannot reach the db then we have connectivity problems
cnn.Open();
// Prepare the command to be executed on the db
using(SqlCommand cmd = new SqlCommand(sql, cnn))
{
// Create and set the parameters values
cmd.Parameters.Add("@first", SqlDbType.NVarChar).Value = textbox2.text;
cmd.Parameters.Add("@last", SqlDbType.NVarChar).Value = textbox3.text;
// Let's ask the db to execute the query
int rowsAdded = cmd.ExecuteNonQuery();
if(rowsAdded > 0)
MessageBox.Show ("Row inserted!!" + );
else
// Well this should never really happen
MessageBox.Show ("No row inserted");
}
}
catch(Exception ex)
{
// We should log the error somewhere,
// for this example let's just show a message
MessageBox.Show("ERROR:" + ex.Message);
}
}
using
statement to be sure that the connection
will be closed and resources released Apart from this, there are other potential problems. What if the user doesn't input anything in the textbox controls? Do you have done any checking on this before trying to insert? As I have said the fields names contain spaces and this will cause inconveniences in your code. Try to change those field names.
This code assumes that your database columns are of type NVARCHAR, if not, then use the appropriate SqlDbType enum value.
Please plan to switch to a more recent version of NET Framework as soon as possible. The 1.1 is really obsolete now.
And, about AddWithValue problems, this article explain why we should avoid it. Can we stop using AddWithValue() already?
@echo off
(echo this is in the first line) > xy.txt
(echo this is in the second line) >> xy.txt
exit
The two >>
means that the second line will be appended to the file (i.e. second line will start after the last line of xy.txt).
this is how the xy.txt
looks like:
this is in the first line
this is in the second line
An AnyCPU assembly will JIT to 64-bit code when loaded into a 64-bit process and 32 bit when loaded into a 32-bit process.
By limiting the CPU you would be saying: There is something being used by the assembly (something likely unmanaged) that requires 32 bits or 64 bits.
In this example:
http://www.example.com:80/somepage?parameter1="hello"¶meter2="world"
the bold part is the Domainname. 80 is rarely included. I post it since many people may wonder if 3000 or some other port is part of the domain if their not staging their app for production yet. Normally you don't specify it since 80 is the default, but if you just want to specify localhost
just do it without the port number, it works just as fine. The adress, though, should be http://localhost:3000
(if you have it on that port).
If you don't want to use str.lower()
, you can use a regular expression:
import re
if re.search('mandy', 'Mandy Pande', re.IGNORECASE):
# Is True
You are using the wrong build.gradle
file.
In your top-level file you can't define an android
block.
Just move this part inside the module/build.gradle
file.
android {
compileSdkVersion 17
buildToolsVersion '23.0.0'
}
dependencies {
compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'
You could use an anonymous type:
.Select(i => new { i.name, i.category_name })
The compiler will generate the code for a class with name
and category_name
properties and returns instances of that class. You can also manually specify property names:
i => new { Id = i.category_id, Name = i.category_name }
You can have arbitrary number of properties.
TFS redefined what "Get Latest" does. In TFS terms, Get Latest means get the latest version of the files, but ignore the ones that the server thinks is already in your workspace. Which to me and just about everyone else on the planet is wrong.
See this link: http://blogs.microsoft.co.il/blogs/srlteam/archive/2009/04/13/how-get-latest-version-really-works.aspx
The only way to get it to do what you want is to Get Specific Version, then check both of the "Overwrite ..." boxes.
FWIW, the real problem was that I had included a semicolon at the end of my \set command:
\set owner_password 'thepassword';
The semicolon was interpreted as an actual character in the variable:
\echo :owner_password thepassword;
So when I tried to use it:
CREATE ROLE myrole LOGIN UNENCRYPTED PASSWORD :owner_password NOINHERIT CREATEDB CREATEROLE VALID UNTIL 'infinity';
...I got this:
CREATE ROLE myrole LOGIN UNENCRYPTED PASSWORD thepassword; NOINHERIT CREATEDB CREATEROLE VALID UNTIL 'infinity';
That not only failed to set the quotes around the literal, but split the command into 2 parts (the second of which was invalid as it started with "NOINHERIT").
The moral of this story: PostgreSQL "variables" are really macros used in text expansion, not true values. I'm sure that comes in handy, but it's tricky at first.
Take the following folder structure
notice:
Now in the index.html.en
file you'll want to put the following markup
<p>
<span>src="check_mark.png"</span>
<img src="check_mark.png" />
<span>I'm purple because I'm referenced from this current directory</span>
</p>
<p>
<span>src="/check_mark.png"</span>
<img src="/check_mark.png" />
<span>I'm green because I'm referenced from the ROOT directory</span>
</p>
<p>
<span>src="subfolder/check_mark.png"</span>
<img src="subfolder/check_mark.png" />
<span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>
<p>
<span>src="/subfolder/check_mark.png"</span>
<img src="/subfolder/check_mark.png" />
<span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>
<p>
<span>src="../subfolder/check_mark.png"</span>
<img src="../subfolder/check_mark.png" />
<span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>
<p>
<span>src="subfolder/subfolder/check_mark.png"</span>
<img src="subfolder/subfolder/check_mark.png" />
<span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>
<p>
<span>src="/subfolder/subfolder/check_mark.png"</span>
<img src="/subfolder/subfolder/check_mark.png" />
<span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>
Now if you load up the index.html.en
file located in the second subfolder
http://example.com/subfolder/subfolder/
This will be your output

In case anybody has tried to access tabs from within an iframe, you may notice it's not possible. The div
of the tab never gets marked as selected, just as hidden or not hidden. The link itself is the only piece marked as selected.
<li class="ui-state-default ui-corner-top ui-tabs-selected ui-state-active ui-state-focus"><a href="#tabs-4">Tab 5</a></li>
The following will get you the href
value of the link which should be the same as the id for your tab container:
jQuery('.ui-tabs-selected a',window.parent.document).attr('href')
This should also work in place of: $tabs.tabs('option', 'selected');
It's better in the sense that instead of just getting the index of the tab, it gives you the actual id of the tab.
In addition to the above explanations, what I experience:
app.use('/book', handler);
will match all requests beginning with '/book' as URL. so it also matches '/book/1' or '/book/2'
app.get('/book')
matches only GET request with exact match. It will not handle URLs like '/book/1' or '/book/2'
So, if you want a global handler that handles all of your routes, then app.use('/')
is the option. app.get('/')
will handle only the root URL.
Petr Krampl's answer is the best in my opinion, but more needs to be said about the nature of loops and how to optimize the use of the system. Beginners who happen upon this thread may be further confused by the logical and algorithmic errors in the question and existing answers.
First, let's look at what your code does as you originally wrote it:
while True:
test = 0
if test == 5:
break
test = test - 1
If you say while True
in a loop context, normally your intention is to stay in the loop forever. If that's not your intention, you should consider other options for the structure of the loop. Petr Krampl showed you a perfectly reasonable way to handle this that's much more clear to someone else who may read your code. In addition, it will be more clear to you several months later should you need to revisit your code to add or fix something. Well-written code is part of your documentation. There are usually multiple ways to do things, but that doesn't make all of the ways equally valid in all contexts. while true
is a good example of this especially in this context.
Next, we will look at the algorithmic error in your original code. The very first thing you do in the loop is assign 0 to test
. The very next thing you do is to check if the value of test
is 5, which will never be the case unless you have multiple threads modifying the same memory location. Threading is not in scope for this discussion, but it's worth noting that the code could technically work, but even with multiple threads a lot would be missing, e.g. semaphores. Anyway, you will sit in this loop forever regardless of the fact that the sentinel is forcing an infinite loop.
The statement test = test - 1
is useless regardless of what it does because the variable is reset at the beginning of the next iteration of the loop. Even if you changed it to be test = 5
, the loop would still be infinite because the value is reset each time. If you move the initialization statement outside the loop, then it will at least have a chance to exit. What you may have intended was something like this:
test = 0
while True:
test = test - 1
if test == 5:
break
The order of the statements in the loop depends on the logic of your program. It will work in either order, though, which is the main point.
The next issue is the potential and probable logical error of starting at 0, continually subtracting 1, and then comparing with a positive number. Yes, there are occasions where this may actually be what you intend to do as long as you understand the implications, but this is most likely not what you intended. Newer versions of python will not wrap around when you reach the 'bottom' of the range of an integer like C and various other languages. It will let you continue to subtract 1 until you've filled the available memory on your system or at least what's allocated to your process. Look at the following script and the results:
test = 0
while True:
test -= 1
if test % 100 == 0:
print "Test = %d" % test
if test == 5:
print "Test = 5"
break
which produces this:
Test = -100
Test = -200
Test = -300
Test = -400
...
Test = -21559000
Test = -21559100
Test = -21559200
Test = -21559300
...
The value of test
will never be 5, so this loop will never exit.
To add to Petr Krampl's answer, here's a version that's probably closer to what you actually intended in addition to exiting the loop after a certain period of time:
import time
test = 0
timeout = 300 # [seconds]
timeout_start = time.time()
while time.time() < timeout_start + timeout:
if test == 5:
break
test -= 1
It still won't break based on the value of test
, but this is a perfectly valid loop with a reasonable initial condition. Further boundary checking could help you to avoid execution of a very long loop for no reason, e.g. check if the value of test is less than 5 upon loop entry, which would immediately break the loop.
One other thing should be mentioned that no other answer has addressed. Sometimes when you loop like this, you may not want to consume the CPU for the entire allotted time. For example, say you are checking the value of something that changes every second. If you don't introduce some kind of delay, you would use every available CPU cycle allotted to your process. That's fine if it's necessary, but good design will allow a lot of programs to run in parallel on your system without overburdening the available resources. A simple sleep statement will free up the vast majority of the CPU cycles allotted to your process so other programs can do work.
The following example isn't very useful, but it does demonstrate the concept. Let's say you want to print something every second. One way to do it would be like this:
import time
tCurrent = time.time()
while True:
if time.time() >= tCurrent + 1:
print "Time = %d" % time.time()
tCurrent = time.time()
The output would be this:
Time = 1498226796
Time = 1498226797
Time = 1498226798
Time = 1498226799
And the process CPU usage would look like this:
That's a huge amount of CPU usage for doing basically no work. This code is much nicer to the rest of the system:
import time
tCurrent = time.time()
while True:
time.sleep(0.25) # sleep for 250 milliseconds
if time.time() >= tCurrent + 1:
print "Time = %d" % time.time()
tCurrent = time.time()
The output is the same:
Time = 1498226796
Time = 1498226797
Time = 1498226798
Time = 1498226799
and the CPU usage is way, way lower:
you make the use of the HTML Helper and have
@using(Html.BeginForm())
{
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
}
or use the Url helper
<form method="post" action="@Url.Action("MyAction", "MyController")" >
Html.BeginForm
has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:
@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
< ... >
}
If you don't specify any arguments, the Html.BeginForm()
will create a POST
form that points to your current controller and current action. As an example, let's say you have a controller called Posts
and an action called Delete
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
return View(model);
}
[HttpPost]
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
if(model != null)
db.DeletePost(id);
return RedirectToView("Index");
}
and your html page would be something like:
<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>

Even if you have unchecked the "Display intranet sites in Compatibility View" option, and have the X-UA-Compatible in your response headers, there is another reason why your browser might default to "Compatibility View" anyways - your Group Policy. Look at your console for the following message:
HTML1203: xxx.xxx has been configured to run in Compatibility View through Group Policy.
Where xxx.xxx is the domain for your site (i.e. test.com). If you see this then the group policy for your domain is set so that any site ending in test.com will automatically render in Compatibility mode regardless of doctype, headers, etc.
For more information, please see the following link (explains the html codes): http://msdn.microsoft.com/en-us/library/ie/hh180764(v=vs.85).aspx
With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:
print *(myVector._M_impl._M_start)@myVector.size()
To print only the first N elements, do:
print *(myVector._M_impl._M_start)@N
Explanation
This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:
myVector._M_impl._M_start
And the GDB command to print N elements of an array starting at pointer P is:
print P@N
Or, in a short form (for a standard .gdbinit):
p P@N
Note that you can also expand part of argument list:
myfun(1, *("foo", "bar"))
To convert all Java files recursively in a directory to use 4 spaces instead of a tab:
find . -type f -name *.java -exec bash -c 'expand -t 4 {} > /tmp/stuff;mv /tmp/stuff {}' \;
If the string is 1 character long, just take that character. If the string is not 1 character long, it cannot be parsed into a character.
I suggest creating a test app (for dev environment only) on https://developers.facebook.com/apps and set: Website with Facebook Login
property to your localhost:[port] settings.
this option will work fine with no need to change hosts.
remember to change the appId back to your production app once you go live.
Edit - in the latest fb version you'll find it under the settings
tab.
Sorry, but the event handler is really not needed. What you do need is another element within the tag to click on.
<a id="test1" href="javascript:alert('test1')">TEST1</a>
<a id="test2" href="javascript:alert('test2')"><span>TEST2</span></a>
Jquery:
$('#test1').trigger('click'); // Nothing
$('#test2').find('span').trigger('click'); // Works
$('#test2 span').trigger('click'); // Also Works
This is all about what you are clicking and it is not the tag but the thing within it. Unfortunately, bare text does not seem to be recognised by JQuery, but it is by vanilla javascript:
document.getElementById('test1').click(); // Works!
Or by accessing the jQuery object as an array
$('#test1')[0].click(); // Works too!!!
In this case, to validate Date (DD-MM-YYYY) or (DD/MM/YYYY), with a year between 1900 and 2099,like this with month and Days validation
if (!Regex.Match(txtDob.Text, @"^(0[1-9]|1[0-9]|2[0-9]|3[0,1])([/+-])(0[1-9]|1[0-2])([/+-])(19|20)[0-9]{2}$").Success)
{
MessageBox.Show("InValid Date of Birth");
txtDob.Focus();
}
Not jQuery, but it works well for a calendar with time: JavaScript Date Time Picker.
I just bound the click event to pop it up:
$(".arrival-date").click(function() {
NewCssCal($(this).attr('id'), 'mmddyyyy', 'dropdown', true, 12);
});
Here is way I tried and found useful,
URL u = new URL(name); // this would check for the protocol
u.toURI(); // does the extra checking required for validation of URI
This happens because of your application does not allow to append iframe from origin other than your application domain.
If your application have web.config then add the following tag in web.config
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="X-Frame-Options" value="ALLOW" />
</customHeaders>
</httpProtocol>
</system.webServer>
This will allow application to append iframe from other origin also. You can also use the following value for X-Frame-Option
X-FRAME-OPTIONS: ALLOW-FROM https://example.com/
The most simple and shortest way to accomplish this:
/[^\p{L}\d\s@#]/u
[^...]
Match a single character not present in the list below
\p{L}
=> matches any kind of letter from any language
\d
=> matches a digit zero through nine
\s
=> matches any kind of invisible character
@#
=> @
and #
characters
Don't forget to pass the u
(unicode) flag.
Merging 2 repos

git update-ref -d refs/remotes/project2/master
First, convert the base 64 string to an Image
, then use the Image.Save
method.
To convert from base 64 string to Image
:
public Image Base64ToImage(string base64String)
{
// Convert base 64 string to byte[]
byte[] imageBytes = Convert.FromBase64String(base64String);
// Convert byte[] to Image
using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
{
Image image = Image.FromStream(ms, true);
return image;
}
}
To convert from Image
to base 64 string:
public string ImageToBase64(Image image,System.Drawing.Imaging.ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
// Convert Image to byte[]
image.Save(ms, format);
byte[] imageBytes = ms.ToArray();
// Convert byte[] to base 64 string
string base64String = Convert.ToBase64String(imageBytes);
return base64String;
}
}
Finally, you can easily to call Image.Save(filePath);
to save the image.
Try this code using VIewWillDisappear
method to detect the press of The back button of NavigationItem:
-(void) viewWillDisappear:(BOOL)animated
{
if ([self.navigationController.viewControllers indexOfObject:self]==NSNotFound)
{
// Navigation button was pressed. Do some stuff
[self.navigationController popViewControllerAnimated:NO];
}
[super viewWillDisappear:animated];
}
OR There is another way to get Action of the Navigation BAck button.
Create Custom button for UINavigationItem of back button .
For Ex:
In ViewDidLoad :
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle:@"Home" style:UIBarButtonItemStyleBordered target:self action:@selector(home:)];
self.navigationItem.leftBarButtonItem=newBackButton;
}
-(void)home:(UIBarButtonItem *)sender
{
[self.navigationController popToRootViewControllerAnimated:YES];
}
Swift :
override func willMoveToParentViewController(parent: UIViewController?)
{
if parent == nil
{
// Back btn Event handler
}
}
It should be :
public async Task<ActionResult> GetSomeJsonData()
{
var model = // ... get data or build model etc.
return Json(new { Data = model }, JsonRequestBehavior.AllowGet);
}
or more simply:
return Json(model, JsonRequestBehavior.AllowGet);
I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...
No one has brought up the hackintosh. If you have supported hardware it might be the best option.
What you are looking for is this:
SHOW VARIABLES;
You can modify it further like any query:
SHOW VARIABLES LIKE '%max%';
This issue boiled down to how I was building my select2 select box. In one javascript file I had...
$(function(){
$(".select2").select2();
});
And in another js file an override...
$(function(){
var employerStateSelector =
$("#registration_employer_state").select2("destroy");
employerStateSelector.select2({
placeholder: 'Select a State...'
});
});
Moving the second override into a window load event resolved the issue.
$( window ).load(function() {
var employerStateSelector =
$("#registration_employer_state").select2("destroy");
employerStateSelector.select2({
placeholder: 'Select a State...'
});
});
This issue blossomed inside a Rails application
You have a wrong idea of what fgets returns. Take a look at this: http://www.cplusplus.com/reference/clibrary/cstdio/fgets/
It returns null when it finds an EOF character. Try running the program above and pressing CTRL+D (or whatever combination is your EOF character), and the loop will exit succesfully.
How do you want to detect the end of the input? Newline? Dot (you said sentence xD)?
The Ternary operator is just written as a boolean expression followed by a questionmark and then two further expressions separated by a colon.
The first thing that I can see that you have got wrong is that your first expression isn't returning a boolean or anything sensible that could be converted to a boolean. Your first expression is always going to return a jQuery object that has no sensible interpretation as a boolean and what it does convert to is probably an unchanging interpretation. You are always best off returning something that has a well known boolean interpretation, if nothign else for the sake of readability.
The second thing is that you are putting a semicolon after each of your expressions which is wrong. In effect this is saying "end of construct" and so is breaking your ternary operator.
In this situation though you probably can do this a more easy way. If you use classes and the toggleClass method then you can easily get it to switch a class on and off and then you can put your styles in that class definition (Kudos to @yoavmatchulsky for suggesting use of classes up there in comments).
A fiddle of this is found here: http://jsfiddle.net/chrisvenus/wSMnV/ (based on the original)
Your solution is correct, but your outer loop is still longer than needed. You don't need to compare the last element with anything else because it's been already compared with all the others in the previous iterations. Your inner loop still prevents that, but since we're talking about collision detection you can save the unnecessary check.
Using the same language you used to illustrate your algorithm, you'd come with something like this:
for (int i = 0, i < mylist.size() - 1; ++i)
for (int j = i + 1, j < mylist.size(); --j)
compare(mylist[i], mylist[j])

I don't understand, why you don't want to set the $HOME
environment variable since that solves exactly what you're asking for.
cd ~
doesn't mean change to the root directory, but change to the user's home directory, which is set by the $HOME
environment variable.
Edit C:\Program Files (x86)\Git\etc\profile
and set $HOME
variable to whatever you want (add it if it's not there). A good place could be for example right after a condition commented by # Set up USER's home directory
. It must be in the MinGW format, for example:
HOME=/c/my/custom/home
Save it, open Git Bash and execute cd ~
. You should be in a directory /c/my/custom/home
now.
Everything that accesses the user's profile should go into this directory instead of your Windows' profile on a network drive.
Note: C:\Program Files (x86)\Git\etc\profile
is shared by all users, so if the machine is used by multiple users, it's a good idea to set the $HOME
dynamically:
HOME=/c/Users/$USERNAME
Set the environment variable HOME
in Windows to whatever directory you want. In this case, you have to set it in Windows path format (with backslashes, e.g. c:\my\custom\home
), Git Bash will load it and convert it to its format.
If you want to change the home directory for all users on your machine, set it as a system environment variable, where you can use for example %USERNAME%
variable so every user will have his own home directory, for example:
HOME=c:\custom\home\%USERNAME%
If you want to change the home directory just for yourself, set it as a user environment variable, so other users won't be affected. In this case, you can simply hard-code the whole path:
HOME=c:\my\custom\home
The built-in string constructor will automatically call obj.__str__
:
''.join(map(str,list))
Don't know if this is relevant to XAML, but in my simple Windows app I created the binding manually and added a Format event handler.
public FormMain() {
InitializeComponent();
Binding argBinding = new Binding("Enabled", uxCheckBoxArgsNull, "Checked", false, DataSourceUpdateMode.OnPropertyChanged);
argBinding.Format += new ConvertEventHandler(Binding_Format_BooleanInverse);
uxTextBoxArgs.DataBindings.Add(argBinding);
}
void Binding_Format_BooleanInverse(object sender, ConvertEventArgs e) {
bool boolValue = (bool)e.Value;
e.Value = !boolValue;
}
I don't think you can make a control look like anything other than a control with CSS.
Your best bet it to make a PRINT button goes to a new page with a graphic in place of the selected radio button, then do a window.print() from there.
Actually, often it is better not to join, in linq that is. When there are navigation properties a very succinct way to write your linq statement is:
from dealer in db.Dealers
from contact in dealer.DealerContacts
select new { whatever you need from dealer or contact }
It translates to a where clause:
SELECT <columns>
FROM Dealer, DealerContact
WHERE Dealer.DealerID = DealerContact.DealerID
This is probably slower than what you want, but you can do:
>>> tostring = vectorize(lambda x: str(x))
>>> numpy.where(tostring(phis).astype('float64') != phis)
(array([], dtype=int64),)
It looks like it rounds off the values when it converts to str from float64, but this way you can customize the conversion however you like.
Another solution I ran across tonight, which worked for my needs, was to add box-sizing
attributes:
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
These attributes force the border to be part of the box model's width and height and correct the issue as well.
According to caniuse.com » box-sizing, box-sizing
is supported in IE8+.
If you're using LESS or Sass there is a Bootstrap mixin for this.
LESS:
.box-sizing(border-box);
Sass:
@include box-sizing(border-box);
Whilst I was looking for my answer for the same question, I found this:
<img src="img.png" style=max-
width:100%;overflow:hidden;border:none;padding:0;margin:0 auto;display:block;" marginheight="0" marginwidth="0">
You can use it inside a tag (iframe or img) the image will adjust based on it's device.
Another possible way could be using conda and pip. Some time you probably want to use just one of those, but if you really need to set up a particular version of python I combine both.
I create a starting conda enviroment with the python I want. As in here https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html. Alternatively you could set up the whole enviroment just using conda.
conda create -n myenv python=3.6.4
Then activate your enviroment with the python you like. This command could change depending on the OS.
source activae myenv
Now you have your python active then you could continue using conda but if you need/want to use pip:
python -m pip -r requirements.txt
Here you have a possible way.
I loved Christopher Currens's solution using IL but for those who don't want to deal with tricky business of including MSIL into their build process I wrote similar function in C#.
Please note though that you can't use generic restriction like where T : Enum
because Enum is special type. Therefore I have to check if given generic type is really enum.
My function is:
public static T GetEnumFromString<T>(string strValue, T defaultValue)
{
// Check if it realy enum at runtime
if (!typeof(T).IsEnum)
throw new ArgumentException("Method GetEnumFromString can be used with enums only");
if (!string.IsNullOrEmpty(strValue))
{
IEnumerator enumerator = Enum.GetValues(typeof(T)).GetEnumerator();
while (enumerator.MoveNext())
{
T temp = (T)enumerator.Current;
if (temp.ToString().ToLower().Equals(strValue.Trim().ToLower()))
return temp;
}
}
return defaultValue;
}
Whenever you use
export someobject
and someobject is
{
"prop1":"Property1",
"prop2":"Property2",
}
the above you can import anywhere using import
or module.js
and there you can use someobject. This is not a restriction that someobject will be an object only it can be a function too, a class or an object.
When you say
new Object()
like you said
new Vue({
el: '#app',
data: []
)}
Here you are initiating an object of class Vue.
I hope my answer explains your query in general and more explicitly.
To extend the given answer with few useful tricks:
var markers = //some array;
var bounds = new google.maps.LatLngBounds();
for(i=0;i<markers.length;i++) {
bounds.extend(markers[i].getPosition());
}
//center the map to a specific spot (city)
map.setCenter(center);
//center the map to the geometric center of all markers
map.setCenter(bounds.getCenter());
map.fitBounds(bounds);
//remove one zoom level to ensure no marker is on the edge.
map.setZoom(map.getZoom()-1);
// set a minimum zoom
// if you got only 1 marker or all markers are on the same address map will be zoomed too much.
if(map.getZoom()> 15){
map.setZoom(15);
}
//Alternatively this code can be used to set the zoom for just 1 marker and to skip redrawing.
//Note that this will not cover the case if you have 2 markers on the same address.
if(count(markers) == 1){
map.setMaxZoom(15);
map.fitBounds(bounds);
map.setMaxZoom(Null)
}
UPDATE:
Further research in the topic show that fitBounds() is a asynchronic
and it is best to make Zoom manipulation with a listener defined before calling Fit Bounds.
Thanks @Tim, @xr280xr, more examples on the topic : SO:setzoom-after-fitbounds
google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
this.setZoom(map.getZoom()-1);
if (this.getZoom() > 15) {
this.setZoom(15);
}
});
map.fitBounds(bounds);
Alternatively if you enable developer mode and (ADB) is still needed you can use connect to the device.
To enable developer Mode you go to Phone Settings > About Phone > tap buildnumber 7 times
once you have it enabled and have the device connected you can start seeing the device in VSCode
"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur. (From other SO answer)
So you can't do anything about it, it is the issue of the server.
But you could use try .. except
block to handle that exception:
from socket import error as SocketError
import errno
try:
response = urllib2.urlopen(request).read()
except SocketError as e:
if e.errno != errno.ECONNRESET:
raise # Not error we are looking for
pass # Handle error here.
// SQL: SELECT * FROM table LIMIT start, maxRows;
Query q = session.createQuery("FROM table");
q.setFirstResult(start);
q.setMaxResults(maxRows);
For future googlers (thousands have now googled this question):
To set your mind at ease, the onClick
event does work with divs in react, so double-check your code syntax.
These are right:
<div onClick={doThis}>
<div onClick={() => doThis()}>
These are wrong:
<div onClick={doThis()}>
<div onClick={() => doThis}>
(and don't forget to close your tags... Watch for this:
<div onClick={doThis}
missing closing tag on the div)
The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.
Thank you all for your help!
If you are just interested in growing, you can update the width
to scrollWidth
, whenever the content of the input
element changes.
document.querySelectorAll('input[type="text"]').forEach(function(node) {
node.onchange = node.oninput = function() {
node.style.width = node.scrollWidth+'px';
};
});
But this will not shrink the element.
According to this video of Android Developers you should only make two changes
To disable all mouse click
var event = $(document).click(function(e) {
e.stopPropagation();
e.preventDefault();
e.stopImmediatePropagation();
return false;
});
// disable right click
$(document).bind('contextmenu', function(e) {
e.stopPropagation();
e.preventDefault();
e.stopImmediatePropagation();
return false;
});
to enable it again:
$(document).unbind('click');
$(document).unbind('contextmenu');
Try this
<form action="" method="POST" id="formaddtask">
Add Task: <input type="text"name="newtaskname" />
<input type="submit" value="Submit"/>
</form>
//Check if the form is submitted
if($_SERVER['REQUEST_METHOD'] == 'POST' && !empty($_POST['newtaskname'])){
}
Use this:
static int RandomNumber(int min, int max)
{
Random random = new Random(); return random.Next(min, max);
}
This is example for you to modify and use in your application.
Above answers assume that UTF8 encoding can safely be used - this one is specifically targetted for Windows.
The Windows console normaly uses CP850 encoding and not utf-8, so if you try to use a source file utf8-encoded, you get those 2 (incorrect) characters -¦
instead of a degree °
.
Demonstration (using python 2.7 in a windows console):
deg = u'\xb0` # utf code for degree
print deg.encode('utf8')
effectively outputs -¦
.
Fix: just force the correct encoding (or better use unicode):
local_encoding = 'cp850' # adapt for other encodings
deg = u'\xb0'.encode(local_encoding)
print deg
or if you use a source file that explicitely defines an encoding:
# -*- coding: utf-8 -*-
local_encoding = 'cp850' # adapt for other encodings
print " The current temperature in the country/city you've entered is " + temp_in_county_or_city + "°C.".decode('utf8').encode(local_encoding)
I was able to get SSL working with the following boilerplate code:
var fs = require('fs'),
http = require('http'),
https = require('https'),
express = require('express');
var port = 8000;
var options = {
key: fs.readFileSync('./ssl/privatekey.pem'),
cert: fs.readFileSync('./ssl/certificate.pem'),
};
var app = express();
var server = https.createServer(options, app).listen(port, function(){
console.log("Express server listening on port " + port);
});
app.get('/', function (req, res) {
res.writeHead(200);
res.end("hello world\n");
});
Sounds like you'd like to use toLocaleString() on your numeric inputs.
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString for its usage.
Localization of numbers in JS is also covered in Internationalization(Number formatting "num.toLocaleString()") not working for chrome

You need to get 2 folders back from your css file.
Try:
background-image: url("../../images/image.png");
In linux (Debian Jessie for example):
apt-get install php7.0-intl
will make the job to you due will create a simbolic link to it.
@Mock
annotation mocks the concerned object.
@InjectMocks
annotation allows to inject into the underlying object the different (and relevant) mocks created by @Mock
.
Both are complementary.

The thought process here is that you spend most of your time in development
. When in development, you create a feature
branch (off of development
), complete the feature, and then merge back into development
. This can then be added to the final production version by merging into production
.
See A Successful Git Branching Model for more detail on this approach.
The permament pool contains everything that is not your application data, but rather things required for the VM: typically it contains interned strings, the byte code of defined classes, but also other "not yours" pieces of data.
ok i spent some frustrating time with this problem too. My little guide.
Open desktop for example. If you didnt switch your disc in cmd, type:
cd desktop
Now if you want to display subfolders:
cd, make 1 spacebar, and press tab 2 times
Now if you want to enter directory/file with SPACE IN NAME. Lets open some file name f.g., to open it we need to type:
cd file\ name
p.s. notice this space after slash :)
nflog is better
sudo apt-get -y install ulogd2
ICMP Block rule example:
iptables=/sbin/iptables
# Drop ICMP (PING)
$iptables -t mangle -A PREROUTING -p icmp -j NFLOG --nflog-prefix 'ICMP Block'
$iptables -t mangle -A PREROUTING -p icmp -j DROP
And you can search prefix "ICMP Block" in log:
/var/log/ulog/syslogemu.log
Your second bit of code starts the first bit of code as a subprocess with piped input and output. It then closes its input and tries to read its output.
The first bit of code tries to read from standard input, but the process that started it closed its standard input, so it immediately reaches an end-of-file, which Python turns into an exception.
When using Object.keys
, the following works:
Object.keys(this)
.forEach(key => {
console.log(this[key as keyof MyClass]);
});
Your answers inspired me to write some macros myself. My requirements were the following:
only write each value of the enum once, so there are no double lists to maintain
don't keep the enum values in a separate file that is later #included, so I can write it wherever I want
don't replace the enum itself, I still want to have the enum type defined, but in addition to it I want to be able to map every enum name to the corresponding string (to not affect legacy code)
the searching should be fast, so preferably no switch-case, for those huge enums
This code creates a classic enum with some values. In addition it creates as std::map which maps each enum value to it's name (i.e. map[E_SUNDAY] = "E_SUNDAY", etc.)
Ok, here is the code now:
EnumUtilsImpl.h:
map<int, string> & operator , (map<int, string> & dest,
const pair<int, string> & keyValue) {
dest[keyValue.first] = keyValue.second;
return dest;
}
#define ADD_TO_MAP(name, value) pair<int, string>(name, #name)

<button type="submit" onClick="refreshPage()">Refresh Button</button>
Assuming you are on Python 3, you can use this syntax
inputs = list(map(str,input().split()))
if you want to access individual element you can do it like that
m, n = map(str,input().split())
An easy way to do this is using the pandas
library like this.
import pandas as pd
fields = ['star_name', 'ra']
df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print df.keys()
# See content in 'star_name'
print df.star_name
The problem here was the skipinitialspace
which remove the spaces in the header. So ' star_name' becomes 'star_name'
In your main.ts
, you are bootstrapping both your AppModule and your App. It should just be the AppModule, which then bootstraps the App.
If you compare your main.ts to the docs you'll see the difference - just remove all references to App from main.ts
A better answer is to leave your script as it was. When doing the Select name
, follow it by -ExpandProperty Name
like so:
Get-ADGroupMember 'Domain Admins' | Select Name -ExpandProperty Name | out-file Admins.txt
In general, you cannot do this. Git does not care how your git repository is named. For example, you can rename directory containing your repository (one with .git
subdirectory), and git will not even notice it - everything will continue to work.
However, if you cloned it, you can use command:
git remote show origin
to display a lot of information about original remote that you cloned your repository from, and it will contain original clone URL.
If, however, you removed link to original remote using git remote rm origin
, or if you created that repository using git init
, such information is simply impossible to obtain - it does not exist anywhere.

The mysqli_query()
method returns an object resource to your $result
variable, not a string.
You need to loop it up and then access the records. You just can't directly use it as your $result
variable.
while ($row = $result->fetch_assoc()) {
echo $row['classtype']."<br>";
}
Official Ruby FAQ: What is the difference between class variables and class instance variables?
The main difference is the behavior concerning inheritance: class variables are shared between a class and all its subclasses, while class instance variables only belong to one specific class.
Class variables in some way can be seen as global variables within the context of an inheritance hierarchy, with all the problems that come with global variables. For instance, a class variable might (accidentally) be reassigned by any of its subclasses, affecting all other classes:
class Woof
@@sound = "woof"
def self.sound
@@sound
end
end
Woof.sound # => "woof"
class LoudWoof < Woof
@@sound = "WOOF"
end
LoudWoof.sound # => "WOOF"
Woof.sound # => "WOOF" (!)
Or, an ancestor class might later be reopened and changed, with possibly surprising effects:
class Foo
@@var = "foo"
def self.var
@@var
end
end
Foo.var # => "foo" (as expected)
class Object
@@var = "object"
end
Foo.var # => "object" (!)
So, unless you exactly know what you are doing and explicitly need this kind of behavior, you better should use class instance variables.
MariaDB has lifted this starting from 10.3.x (both for DELETE
and UPDATE
):
UPDATE - Statements With the Same Source and Target
From MariaDB 10.3.2, UPDATE statements may have the same source and target.
Until MariaDB 10.3.1, the following UPDATE statement would not work:
UPDATE t1 SET c1=c1+1 WHERE c2=(SELECT MAX(c2) FROM t1); ERROR 1093 (HY000): Table 't1' is specified twice, both as a target for 'UPDATE' and as a separate source for data
From MariaDB 10.3.2, the statement executes successfully:
UPDATE t1 SET c1=c1+1 WHERE c2=(SELECT MAX(c2) FROM t1);
DELETE - Same Source and Target Table
Until MariaDB 10.3.1, deleting from a table with the same source and target was not possible. From MariaDB 10.3.1, this is now possible. For example:
DELETE FROM t1 WHERE c1 IN (SELECT b.c1 FROM t1 b WHERE b.c2=0);
Edit: You didn't say you had pushed to a public repo! That makes a world of difference.
There are two ways, the "dirty" way and the "clean" way. Suppose your branch is named new-master
. This is the clean way:
git checkout new-master
git branch -m master old-master
git branch -m new-master master
# And don't do this part. Just don't. But if you want to...
# git branch -d --force old-master
This will make the config files change to match the renamed branches.
You can also do it the dirty way, which won't update the config files. This is kind of what goes on under the hood of the above...
mv -i .git/refs/new-master .git/refs/master
git checkout master
This makefile
will generate the 'missing separator' error message:
all
@echo NDK_PROJECT_PATH=$(NDK_PROJECT_PATH)
done:
@echo "All done"
There's a tab before the @echo "All done"
(though the done:
rule and action are largely superfluous), but not before the @echo PATH=$(PATH)
.
The trouble is that the line starting all
should either have a colon :
or an equals =
to indicate that it is a target line or a macro line, and it has neither, so the separator is missing.
The action that echoes the value of a variable must be associated with a target, possibly a dummy or PHONEY target. And that target line must have a colon on it. If you add a :
after all
in the example makefile
and replace the leading blanks on the next line by a tab, it will work sanely.
You probably have an analogous problem near line 102 in the original makefile
. If you showed 5 non-blank, non-comment lines before the echo operations that are failing, it would probably be possible to finish the diagnosis. However, since the question was asked in May 2013, it is unlikely that the broken makefile
is still available now (August 2014), so this answer can't be validated formally. It can only be used to illustrate a plausible way in which the problem occurred.
I faced this exception while I was doing APIs for ElasticSearch using Spring Data. I did the following and it worked.
@SpringDataApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
If you're using Atom editor, you can accomplish this by the ascii-tree package.
You can write the following tree:
root
+-- dir1
+--file1
+-- dir2
+-- file2
and convert it to the following by selecting it and pressing ctrl-alt-t
:
root
+-- dir1
¦ +-- file1
+-- dir2
+-- file2
The quick and dirty way is using json_encode
and json_decode
which will turn the entire array (including sub elements) into an object.
$clasa = json_decode(json_encode($clasa)); //Turn it into an object
The same can be used to convert an object into an array. Simply add , true
to json_decode
to return an associated array:
$clasa = json_decode(json_encode($clasa), true); //Turn it into an array
An alternate way (without being dirty) is simply a recursive function:
function convertToObject($array) {
$object = new stdClass();
foreach ($array as $key => $value) {
if (is_array($value)) {
$value = convertToObject($value);
}
$object->$key = $value;
}
return $object;
}
or in full code:
<?php
function convertToObject($array) {
$object = new stdClass();
foreach ($array as $key => $value) {
if (is_array($value)) {
$value = convertToObject($value);
}
$object->$key = $value;
}
return $object;
}
$clasa = array(
'e1' => array('nume' => 'Nitu', 'prenume' => 'Andrei', 'sex' => 'm', 'varsta' => 23),
'e2' => array('nume' => 'Nae', 'prenume' => 'Ionel', 'sex' => 'm', 'varsta' => 27),
'e3' => array('nume' => 'Noman', 'prenume' => 'Alice', 'sex' => 'f', 'varsta' => 22),
'e4' => array('nume' => 'Geangos', 'prenume' => 'Bogdan', 'sex' => 'm', 'varsta' => 23),
'e5' => array('nume' => 'Vasile', 'prenume' => 'Mihai', 'sex' => 'm', 'varsta' => 25)
);
$obj = convertToObject($clasa);
print_r($obj);
?>
which outputs (note that there's no arrays - only stdClass
's):
stdClass Object
(
[e1] => stdClass Object
(
[nume] => Nitu
[prenume] => Andrei
[sex] => m
[varsta] => 23
)
[e2] => stdClass Object
(
[nume] => Nae
[prenume] => Ionel
[sex] => m
[varsta] => 27
)
[e3] => stdClass Object
(
[nume] => Noman
[prenume] => Alice
[sex] => f
[varsta] => 22
)
[e4] => stdClass Object
(
[nume] => Geangos
[prenume] => Bogdan
[sex] => m
[varsta] => 23
)
[e5] => stdClass Object
(
[nume] => Vasile
[prenume] => Mihai
[sex] => m
[varsta] => 25
)
)
So you'd refer to it by $obj->e5->nume
.
The delete[]
operator is used to delete arrays. The delete
operator is used to delete non-array objects. It calls operator delete[]
and operator delete
function respectively to delete the memory that the array or non-array object occupied after (eventually) calling the destructors for the array's elements or the non-array object.
The following shows the relations:
typedef int array_type[1];
// create and destroy a int[1]
array_type *a = new array_type;
delete [] a;
// create and destroy an int
int *b = new int;
delete b;
// create and destroy an int[1]
int *c = new int[1];
delete[] c;
// create and destroy an int[1][2]
int (*d)[2] = new int[1][2];
delete [] d;
For the new
that creates an array (so, either the new type[]
or new
applied to an array type construct), the Standard looks for an operator new[]
in the array's element type class or in the global scope, and passes the amount of memory requested. It may request more than N * sizeof(ElementType)
if it wants (for instance to store the number of elements, so it later when deleting knows how many destructor calls to done). If the class declares an operator new[]
that additional to the amount of memory accepts another size_t
, that second parameter will receive the number of elements allocated - it may use this for any purpose it wants (debugging, etc...).
For the new
that creates a non-array object, it will look for an operator new
in the element's class or in the global scope. It passes the amount of memory requested (exactly sizeof(T)
always).
For the delete[]
, it looks into the arrays' element class type and calls their destructors. The operator delete[]
function used is the one in the element type's class, or if there is none then in the global scope.
For the delete
, if the pointer passed is a base class of the actual object's type, the base class must have a virtual destructor (otherwise, behavior is undefined). If it is not a base class, then the destructor of that class is called, and an operator delete
in that class or the global operator delete
is used. If a base class was passed, then the actual object type's destructor is called, and the operator delete
found in that class is used, or if there is none, a global operator delete
is called. If the operator delete
in the class has a second parameter of type size_t
, it will receive the number of elements to deallocate.
Choice one! But the first is very simple. The last maybe util for file manipulation:
//Method 1 (I like this)
File.AppendAllLines(
"FileAppendAllLines.txt",
new string[] { "line1", "line2", "line3" });
//Method 2
File.AppendAllText(
"FileAppendAllText.txt",
"line1" + Environment.NewLine +
"line2" + Environment.NewLine +
"line3" + Environment.NewLine);
//Method 3
using (StreamWriter stream = File.AppendText("FileAppendText.txt"))
{
stream.WriteLine("line1");
stream.WriteLine("line2");
stream.WriteLine("line3");
}
//Method 4
using (StreamWriter stream = new StreamWriter("StreamWriter.txt", true))
{
stream.WriteLine("line1");
stream.WriteLine("line2");
stream.WriteLine("line3");
}
//Method 5
using (StreamWriter stream = new FileInfo("FileInfo.txt").AppendText())
{
stream.WriteLine("line1");
stream.WriteLine("line2");
stream.WriteLine("line3");
}
I found this article to be very useful. In particular, the following example:
#!/usr/bin/ruby
def test
yield 5
puts "You are in the method test"
yield 100
end
test {|i| puts "You are in the block #{i}"}
test do |i|
puts "You are in the block #{i}"
end
which should give the following output:
You are in the block 5
You are in the method test
You are in the block 100
You are in the block 5
You are in the method test
You are in the block 100
So essentially each time a call is made to yield
ruby will run the code in the do
block or inside {}
. If a parameter is provided to yield
then this will be provided as a parameter to the do
block.
For me, this was the first time that I understood really what the do
blocks were doing. It is basically a way for the function to give access to internal data structures, be that for iteration or for configuration of the function.
So when in rails you write the following:
respond_to do |format|
format.html { render template: "my/view", layout: 'my_layout' }
end
This will run the respond_to
function which yields the do
block with the (internal) format
parameter. You then call the .html
function on this internal variable which in turn yields the code block to run the render
command. Note that .html
will only yield if it is the file format requested. (technicality: these functions actually use block.call
not yield
as you can see from the source but the functionality is essentially the same, see this question for a discussion.) This provides a way for the function to perform some initialisation then take input from the calling code and then carry on processing if required.
Or put another way, it's similar to a function taking an anonymous function as an argument and then calling it in javascript.
I'm interested in this as well. The only explanation I've found is that xsd:include
is used for intra-namespace inclusions, while xsd:import
is for inter-namespace inclusion.
I guess I will start you off with the time complexity of a linked list:
Indexing---->O(n)
Inserting / Deleting at end---->O(1) or O(n)
Inserting / Deleting in middle--->O(1) with iterator O(n) with out
The time complexity for the Inserting at the end depends if you have the location of the last node, if you do, it would be O(1) other wise you will have to search through the linked list and the time complexity would jump to O(n).
All of the code above was really helpful, but none of it quite answered my own need: grep
all *.tar.gz
files in the current directory to find a pattern that is specified as an argument in a reusable script to output:
It's what I was really hoping that zgrep
could do for me and it just can't.
Here's my solution:
pattern=$1
for f in *.tar.gz; do
echo "$f:"
tar -xzf "$f" --to-command 'grep --label="`basename $TAR_FILENAME`" -Hin '"$pattern ; true";
done
You can also replace the tar
line with the following if you'd like to test that all variables are expanding properly with a basic echo
statement:
tar -xzf "$f" --to-command 'echo "f:`basename $TAR_FILENAME` s:'"$pattern\""
Let me explain what's going on. Hopefully, the for
loop and the echo
of the archive filename in question is obvious.
tar -xzf
: x
extract, z
filter through gzip, f
based on the following archive file...
"$f"
: The archive file provided by the for loop (such as what you'd get by doing an ls
) in double-quotes to allow the variable to expand and ensure that the script is not broken by any file names with spaces, etc.
--to-command
: Pass the output of the tar command to another command rather than actually extracting files to the filesystem. Everything after this specifies what the command is (grep
) and what arguments we're passing to that command.
Let's break that part down by itself, since it's the "secret sauce" here.
'grep --label="`basename $TAR_FILENAME`" -Hin '"$pattern ; true"
First, we use a single-quote to start this chunk so that the executed sub-command (basename $TAR_FILENAME
) is not immediately expanded/resolved. More on that in a moment.
grep
: The command to be run on the (not actually) extracted files
--label=
: The label to prepend the results, the value of which is enclosed in double-quotes because we do want to have the grep
command resolve the $TAR_FILENAME
environment variable passed in by the tar
command.
basename $TAR_FILENAME
: Runs as a command (surrounded by backticks) and removes directory path and outputs only the name of the file
-Hin
: H
Display filename (provided by the label), i
Case insensitive search, n
Display line number of match
Then we "end" the first part of the command string with a single quote and start up the next part with a double quote so that the $pattern
, passed in as the first argument, can be resolved.
Realizing which quotes I needed to use where was the part that tripped me up the longest. Hopefully, this all makes sense to you and helps someone else out. Also, I hope I can find this in a year when I need it again (and I've forgotten about the script I made for it already!)
And it's been a bit a couple of weeks since I wrote the above and it's still super useful... but it wasn't quite good enough as files have piled up and searching for things has gotten more messy. I needed a way to limit what I looked at by the date of the file (only looking at more recent files). So here's that code. Hopefully it's fairly self-explanatory.
if [ -z "$1" ]; then
echo "Look within all tar.gz files for a string pattern, optionally only in recent files"
echo "Usage: targrep <string to search for> [start date]"
fi
pattern=$1
startdatein=$2
startdate=$(date -d "$startdatein" +%s)
for f in *.tar.gz; do
filedate=$(date -r "$f" +%s)
if [[ -z "$startdatein" ]] || [[ $filedate -ge $startdate ]]; then
echo "$f:"
tar -xzf "$f" --to-command 'grep --label="`basename $TAR_FILENAME`" -Hin '"$pattern ; true"
fi
done
And I can't stop tweaking this thing. I added an argument to filter by the name of the output files in the tar file. Wildcards work, too.
Usage:
targrep.sh [-d <start date>] [-f <filename to include>] <string to search for>
Example:
targrep.sh -d "1/1/2019" -f "*vehicle_models.csv" ford
while getopts "d:f:" opt; do
case $opt in
d) startdatein=$OPTARG;;
f) targetfile=$OPTARG;;
esac
done
shift "$((OPTIND-1))" # Discard options and bring forward remaining arguments
pattern=$1
echo "Searching for: $pattern"
if [[ -n $targetfile ]]; then
echo "in filenames: $targetfile"
fi
startdate=$(date -d "$startdatein" +%s)
for f in *.tar.gz; do
filedate=$(date -r "$f" +%s)
if [[ -z "$startdatein" ]] || [[ $filedate -ge $startdate ]]; then
echo "$f:"
if [[ -z "$targetfile" ]]; then
tar -xzf "$f" --to-command 'grep --label="`basename $TAR_FILENAME`" -Hin '"$pattern ; true"
else
tar -xzf "$f" --no-anchored "$targetfile" --to-command 'grep --label="`basename $TAR_FILENAME`" -Hin '"$pattern ; true"
fi
fi
done
To get the script, that currently loaded the script you can use
var thisScript = document.currentScript;
You need to keep a reference at the beginning of your script, so you can call later
var url = thisScript.src
I like this method:
import datetime, time
dts = datetime.datetime.utcnow()
epochtime = round(time.mktime(dts.timetuple()) + dts.microsecond/1e6)
The other methods posted here are either not guaranteed to give you UTC on all platforms or only report whole seconds. If you want full resolution, this works, to the micro-second.
Had same error with code:

You can install the Microsoft Report Viewer 2012 Runtime and change your references so they point to the ones installed by the runtime.
http://www.microsoft.com/en-gb/download/details.aspx?id=35747
I have installed the runtime without it asking for SQL Server 2012. Before installing try uninstalling any previous versions of report viewer.
For some further information on how to determine the processing time, and a comparison of a few methods (some mentioned already in the answers of this post) - specifically, the difference between:
start = time.time()
versus the now obsolete (as of 3.3, time.clock() is deprecated)
start = time.clock()
see this other article on Stackoverflow here:
Python - time.clock() vs. time.time() - accuracy?
If nothing else, this will work good:
start = time.time()
... do something
elapsed = (time.time() - start)
The basic difference is the syntax. While SASS has a loose syntax with white space and no semicolons, the SCSS resembles more to CSS.
If you are planing to use the same image for retina and non-retina screen then here is the solution. Say that you have a image of 200x200
and have two icons in top row and two icon in bottom row. So, it's four quadrants.
.sprite-of-icons {
background: url("../images/icons-in-four-quad-of-200by200.png") no-repeat;
background-size: 100px 100px /* Scale it down to 50% rather using 200x200 */
}
.sp-logo-1 { background-position: 0 0; }
/* Reduce positioning of the icons down to 50% rather using -50px */
.sp-logo-2 { background-position: -25px 0 }
.sp-logo-3 { background-position: 0 -25px }
.sp-logo-3 { background-position: -25px -25px }
Scaling and positioning of the sprite icons to 50% than actual value, you can get the expected result.

i founded and my solution : you have 2 way to resolve it in java :
testEditText.setInputType(InputType.TYPE_CLASS_TEXT
| InputType.TYPE_TEXT_FLAG_CAP_WORDS);
and xml :
<EditText
android:id="@+id/mytxt"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textCapWords"
android:textSize="12sp" />
When it is on server side, use web services - maybe RESTful with JSON.
When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.
Below is example from documentation. Look at methodReturningString
.
Java code:
public class MethodInvocation extends Applet {
public void noArgMethod() { ... }
public void someMethod(String arg) { ... }
public void someMethod(int arg) { ... }
public int methodReturningInt() { return 5; }
public String methodReturningString() { return "Hello"; }
public OtherClass methodReturningObject() { return new OtherClass(); }
}
public class OtherClass {
public void anotherMethod();
}
Web page and JavaScript code:
<applet id="app"
archive="examples.jar"
code="MethodInvocation" ...>
</applet>
<script language="javascript">
app.noArgMethod();
app.someMethod("Hello");
app.someMethod(5);
var five = app.methodReturningInt();
var hello = app.methodReturningString();
app.methodReturningObject().anotherMethod();
</script>
Just to add to the existing answers, I don't see anyone mentioning that python requests is not a native library. If you are ok with adding dependencies, then requests is fine. However, if you are trying to avoid adding dependencies, urllib is a native python library that is already available to you.

Also, applying display:table-header-group or table-footer-group is a handy way of jumping 'row' elements to the top/bottom of the 'table'.
Oracle has a page for this issue with SQL and trouble shooting suggestions.

there is no command directly to draw Triangle. For Drawing of triangle we have to use the concept of lines here.
i.e, g.drawLines(Coordinates of points)
The above answers are good but with Express and node this will work fine.
Since express create the app for you, I'll skip that here.
var express = require('express')
, fs = require('fs')
, routes = require('./routes');
var privateKey = fs.readFileSync('cert/key.pem').toString();
var certificate = fs.readFileSync('cert/certificate.pem').toString();
// To enable HTTPS
var app = module.exports = express.createServer({key: privateKey, cert: certificate});
If you want to exclude the sub-directories, you can use
git diff <ref1>..<ref2> -- $(git diff <ref1>..<ref2> --name-only | grep -v /)
The best way is not to write your own funcion.
Let me explain the motivaion - please lookup the official Android source code.
In TypedValue.java
we have:
public static int complexToDimensionPixelSize(int data,
DisplayMetrics metrics)
{
final float value = complexToFloat(data);
final float f = applyDimension(
(data>>COMPLEX_UNIT_SHIFT)&COMPLEX_UNIT_MASK,
value,
metrics);
final int res = (int) ((f >= 0) ? (f + 0.5f) : (f - 0.5f));
if (res != 0) return res;
if (value == 0) return 0;
if (value > 0) return 1;
return -1;
}
and:
public static float applyDimension(int unit, float value,
DisplayMetrics metrics)
{
switch (unit) {
case COMPLEX_UNIT_PX:
return value;
case COMPLEX_UNIT_DIP:
return value * metrics.density;
case COMPLEX_UNIT_SP:
return value * metrics.scaledDensity;
case COMPLEX_UNIT_PT:
return value * metrics.xdpi * (1.0f/72);
case COMPLEX_UNIT_IN:
return value * metrics.xdpi;
case COMPLEX_UNIT_MM:
return value * metrics.xdpi * (1.0f/25.4f);
}
return 0;
}
As you can see, DisplayMetrics metrics
can differ, which means it would yield different values across Android-OS powered devices.
I strongly recommend putting your dp padding in dimen xml file and use the official Android conversions to have consistent behaviour with regard to how Android framework works.

If you don't have Your own Data Class, then you can design your map as follows
Map<Integer, Object> map=new HashMap<Integer, Object>();
Here don't forget to use "instanceof" operator while retrieving the values from MAP.
If you have your own Data class then then you can design your map as follows

I think to add timestamp to every record and get the latest. In this situation you can get any ids, pack rows and other ops.
first off, to be a bit of a henpeck, its best NOT to use just the <background>
tag. rather, use the proper, more specific, <background-image>
tag.
the only way that i'm aware of to do such a thing is to build the padding into the image by extending the matte. since the empty pixels aren't stripped, you have your padding right there. so if you need a 10px border, create 10px of empty pixels all around your image. this is mui simple in Photoshop, Fireworks, GIMP, &c.
i'd also recommend trying out the PNG8 format instead of the dying GIF... much better.
there may be an alternate solution to your problem if we knew a bit more of how you're using it. :) it LOOKS like you're trying to add an accordion button. this would be best placed in the HTML because then you can target it with JavaScript/PHP; something you cannot do if it's in the background (at least not simply). in such a case, you can style the heck out of the image you currently have in CSS by using the following:
#hello img { padding: 10px; }
WR!
I was also facing such an issue while dockerizing our existing application. The solution si to add allowPublicKeyRetrieval connection option of MySQL with a value of true to the JDBC connection string. If that is not working , try adding useSSL option to false as well .
The resultant string would look like this :
jdbc:mysql://<database server ip>:3306/databaseName?allowPublicKeyRetrieval=true&useSSL=false
What you are doing will not work for root user. Maybe you are running your services as root and hence you don't get to see the change.
To increase the ulimit for root user you should replace the *
by root. *
does not apply for root user. Rest is the same as you did. I will re-quote it here.
Add the following lines to the file: /etc/security/limits.conf
root soft nofile 40000
root hard nofile 40000
And then add following line in the file: /etc/pam.d/common-session
session required pam_limits.so
This will update the ulimit for root user. As mentioned in comments, you may don't even have to reboot to see the change.
Two issues surrounding this question are memory management and thread safety. As you can see from the numerous posts, this isn't an easy task to accomplish seamlessly in C. I desired a solution that is:
The solution I came up meets all of these criteria. It's probably a little more work to setup than some other solutions posted here, but I think that in practice, the extra work is worth it in order to avoid the common pitfalls of other solutions.

Java provides the static method System.currentTimeMillis()
. And that's returning a long value, so it's a good reference. A lot of other classes accept a 'timeInMillis' parameter which is long as well.
And a lot of people find it easier to use the Joda Time library to do calculations on dates and times.
Here is an example that will focus on an input using refs (tested in React 16.8.6):
The Child component:
class Child extends React.Component {
constructor(props) {
super(props);
this.myRef = React.createRef();
}
render() {
return (<input type="text" ref={this.myRef} />);
}
}
The Parent component with the Child component inside:
class Parent extends React.Component {
constructor(props) {
super(props);
this.childRef = React.createRef();
}
componentDidMount() {
this.childRef.current.myRef.current.focus();
}
render() {
return <Child ref={this.childRef} />;
}
}
ReactDOM.render(
<Parent />,
document.getElementById('container')
);
The Parent component with this.props.children:
class Parent extends React.Component {
constructor(props) {
super(props);
this.childRef = React.createRef();
}
componentDidMount() {
this.childRef.current.myRef.current.focus();
}
render() {
const ChildComponentWithRef = React.forwardRef((props, ref) =>
React.cloneElement(this.props.children, {
...props,
ref
})
);
return <ChildComponentWithRef ref={this.childRef} />
}
}
ReactDOM.render(
<Parent>
<Child />
</Parent>,
document.getElementById('container')
);
ConcurrentLinkedQueue
If you don't care about having index-based access and just want the insertion-order-preserving characteristics of a List, you could consider a java.util.concurrent.ConcurrentLinkedQueue
. Since it implements Iterable, once you've finished adding all the items, you can loop over the contents using the enhanced for syntax:
Queue<String> globalQueue = new ConcurrentLinkedQueue<String>();
//Multiple threads can safely call globalQueue.add()...
for (String href : globalQueue) {
//do something with href
}
