A quick Google search turns up these two possibilities:
There are a number of ways to do this, but the cleanest approach has been lost among the top answers and loads of arguments over val()
. Also some methods changed as of jQuery 1.6, so this needs an update.
For the following examples I will assume the variable $select
is a jQuery object pointing at the desired <select>
tag, e.g. via the following:
var $select = $('.selDiv .opts');
For value matching, using val()
is far simpler than using an attribute selector: https://jsfiddle.net/yz7tu49b/6/
$select.val("SEL2");
The setter version of .val()
is implemented on select
tags by setting the selected
property of a matching option
with the same value
, so works just fine on all modern browsers.
If you want to set the selected state of an option directly, you can use prop
(not attr
) with a boolean
parameter (rather than the text value selected
):
e.g. https://jsfiddle.net/yz7tu49b/
$option.prop('selected', true); // Will add selected="selected" to the tag
If you use val()
to select an <option>
, but the val is not matched (might happen depending on the source of the values), then "nothing" is selected and $select.val()
will return null
.
So, for the example shown, and for the sake of robustness, you could use something like this https://jsfiddle.net/1250Ldqn/:
var $select = $('.selDiv .opts');
$select.val("SEL2");
if ($select.val() == null) {
$select.val("DEFAULT");
}
If you want to match by exact text, you can use a filter
with function. e.g. https://jsfiddle.net/yz7tu49b/2/:
var $select = $('.selDiv .opts');
$select.children().filter(function(){
return this.text == "Selection 2";
}).prop('selected', true);
although if you may have extra whitespace you may want to add a trim to the check as in
return $.trim(this.text) == "some value to match";
If you want to match by index just index the children of the select e.g. https://jsfiddle.net/yz7tu49b/3/
var $select = $('.selDiv .opts');
var index = 2;
$select.children()[index].selected = true;
Although I tend to avoid direct DOM properties in favour of jQuery nowadays, to future-proof code, so that could also be done as https://jsfiddle.net/yz7tu49b/5/:
var $select = $('.selDiv .opts');
var index = 2;
$select.children().eq(index).prop('selected', true);
In all the above cases, the change event does not fire. This is by design so that you do not wind up with recursive change events.
To generate the change event, if required, just add a call to .change()
to the jQuery select
object. e.g. the very first simplest example becomes https://jsfiddle.net/yz7tu49b/7/
var $select = $('.selDiv .opts');
$select.val("SEL2").change();
There are also plenty of other ways to find the elements using attribute selectors, like [value="SEL2"]
, but you have to remember attribute selectors are relatively slow compared to all these other options.
Using tee with option -a (--append) allows you to append to multiple files at once and also to use sudo (very useful when appending to protected files). Besides that, it is interesting if you need to use other shells besides bash, as not all shells support the > and >> operators
echo "hello world" | sudo tee -a output.txt
This thread has good answers about tee
Your regex is good altough I would replace it with the empty string
String resultString = subjectString.replaceAll("[\t\n\r]", "");
You expect a space between "text." and "And" right?
I get that space when I try the regex by copying your sample
"This is my text. "
So all is well here. Maybe if you just replace it with the empty string it will work. I don't know why you replace it with \s. And the alternation | is not necessary in a character class.
<context:component-scan base-package="" />
tells Spring to scan those packages for Annotations.
<mvc:annotation-driven>
registers a RequestMappingHanderMapping, a RequestMappingHandlerAdapter, and an ExceptionHandlerExceptionResolver to support the annotated controller methods like @RequestMapping, @ExceptionHandler, etc. that come with MVC.
This also enables a ConversionService that supports Annotation driven formatting of outputs as well as Annotation driven validation for inputs. It also enables support for @ResponseBody which you can use to return JSON data.
You can accomplish the same things using Java-based Configuration using @ComponentScan(basePackages={"...", "..."} and @EnableWebMvc in a @Configuration class.
Check out the 3.1 documentation to learn more.

The following worked for me:
ax2.xaxis.set_tick_params(labelsize=7)
ax2.yaxis.set_tick_params(labelsize=7)
The advantage of the above is you do not need to provide the array
of labels
and works with any data on the axes
.
The common name in the certicate for api.evercam.io
is for *.herokuapp.com
and there are no alternative subject names in the certificate. This means, that the certificate for api.evercam.io
does not match the hostname and therefore the certificate verification fails.
Same as true for www.evercam.io
, e.g. try https://www.evercam.io with a browser and you get the error message, that the name in the certificate does not match the hostname.
So it is a problem which needs to be fixed by evercam.io. If you don't care about security, man-in-the-middle attacks etc you might disable verification of the certificate (curl --insecure
), but then you should ask yourself why you use https instead of http at all.

In my case just work when i add "project" to compile:
repositories {
mavenCentral()
flatDir {
dirs 'libs'
}
}
dependencies {
compile project('com.x.x:x:1.0.0')
}
I'd like to provide an alternate solution, a robust solution similar to what I am about to propose was required in the latest version of ggtern, since introducing the canvas rotation feature.
Basically, you need to determine the relative positions using trigonometry, by building a function which returns an element_text
object, given angle (ie degrees) and positioning (ie one of x,y,top or right) information.
#Load Required Libraries
library(ggplot2)
library(gridExtra)
#Build Function to Return Element Text Object
rotatedAxisElementText = function(angle,position='x'){
angle = angle[1];
position = position[1]
positions = list(x=0,y=90,top=180,right=270)
if(!position %in% names(positions))
stop(sprintf("'position' must be one of [%s]",paste(names(positions),collapse=", ")),call.=FALSE)
if(!is.numeric(angle))
stop("'angle' must be numeric",call.=FALSE)
rads = (angle - positions[[ position ]])*pi/180
hjust = 0.5*(1 - sin(rads))
vjust = 0.5*(1 + cos(rads))
element_text(angle=angle,vjust=vjust,hjust=hjust)
}
Frankly, in my opinion, I think that an 'auto' option should be made available in ggplot2
for the hjust
and vjust
arguments, when specifying the angle, anyway, lets demonstrate how the above works.
#Demonstrate Usage for a Variety of Rotations
df = data.frame(x=0.5,y=0.5)
plots = lapply(seq(0,90,length.out=4),function(a){
ggplot(df,aes(x,y)) +
geom_point() +
theme(axis.text.x = rotatedAxisElementText(a,'x'),
axis.text.y = rotatedAxisElementText(a,'y')) +
labs(title = sprintf("Rotated %s",a))
})
grid.arrange(grobs=plots)
Which produces the following:
Using serialize and unserialize on cookies is a security risk. Users (or attackers) can alter cookie data, then when you unserialize it, it could run PHP code on your server. Cookie data should not be trusted. Use JSON instead!
From PHP's site:
Do not pass untrusted user input to
unserialize()
regardless of theoptions
value of allowed_classes. Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Use a safe, standard data interchange format such as JSON (viajson_decode()
andjson_encode()
) if you need to pass serialized data to the user.
response.setContentType("text/html");
Above code would be include in "HTTP response" to inform the browser about the format of the response, so that the browser can interpret it.
I didn't want to have so many lines of code just to play a simple damn sound. This can work if you have the JavaFX package (already included in my jdk 8).
private static void playSound(String sound){
// cl is the ClassLoader for the current class, ie. CurrentClass.class.getClassLoader();
URL file = cl.getResource(sound);
final Media media = new Media(file.toString());
final MediaPlayer mediaPlayer = new MediaPlayer(media);
mediaPlayer.play();
}
Notice : You need to initialize JavaFX. A quick way to do that, is to call the constructor of JFXPanel() once in your app :
static{
JFXPanel fxPanel = new JFXPanel();
}
Here is a stripped down example, using as little HTML markup as possible.
The overlay is provided by the :before
pseudo element on the .content
container.
No z-index is required, :before
is naturally layered over the video element.
The .content
container is position: relative
so that the position: absolute
overlay is positioned in relation to it.
The overlay is stretched to cover the entire .content
div width with left / right / bottom
and left
set to 0
.
The width of the video is controlled by the width of its container with width: 100%
.content {
position: relative;
width: 500px;
margin: 0 auto;
padding: 20px;
}
.content video {
width: 100%;
display: block;
}
.content:before {
content: '';
position: absolute;
background: rgba(0, 0, 0, 0.5);
border-radius: 5px;

Regarding the difference between an object
and an instance
, I do not think there is any consensus.
It looks to me like people change it pretty much interchangeably, in papers, blog posts, books or conversations.
As for me, the way I see it is, an object is a generic and alive entity in the memory, specified by the language it is used in. Just like the Object
class in Java
. We do not much care its type, or anything else associated with it, whether it is managed by a container or not.
An instance
is an object
but associated with a type, as in this method accepts Foo instances
, or you can not put Animal instances in an instance of
a List of Vehicles
.
object
s for example have locks
associated with them, not instance
s, whereas instance
s have methods. objects
are garbage collected, not instance
s.
But as I said, this is only how I see it, and I do not think there is any organisation we can refer to for a standard definition between them and everyone will pretty much have their slightly different understanding / definitions (of course within limits).

Be careful when you simply append values of variables to your statements:
Imagine a user naming himself ';DROP TABLE Users;'
--
That's why you need to use sql escaping, which Python provides for you when you use the cursor.execute in a decent manner. Example in the url is:
cursor.execute("insert into Attendees values (?, ?, ?)", (name,
seminar, paid) )
The Java Language Specification(1) describes how try-catch-finally
is executed.
Having no catch is equivalent to not having a catch able to catch the given Throwable.
- If execution of the try block completes abruptly because of a throw of a value V, then there is a choice:
- If the run-time type of V is assignable to the parameter of any catch clause of the try statement, then …
…- If the run-time type of V is not assignable to the parameter of any catch clause of the try statement, then the finally block is executed. Then there is a choice:
- If the finally block completes normally, then the try statement completes abruptly because of a throw of the value V.
- If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S (and the throw of value V is discarded and forgotten).
Steps to remove index.php from url for your wordpress website.
<?php
phpinfo?();
?>
Now run this file - www.yoursite.com/phpinfo.php and it will show mod_rewrite at Load modules section. If not enabled then perform below commands at your terminal.
sudo a2enmod rewrite
sudo service apache2 restart
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Further make permission of .htaccess to 666 so that it become writable and now you can do changes in your wordpress permalinks.
Now go to Settings -> permalinks -> and change to your needed url format. Remove this code /index.php/%year%/%monthnum%/%day%/%postname%/ and insert this code on Custom Structure: /%postname%/
If still not succeeded then check your hosting, mine was digitalocean server, so I cleared it myself
Edited the file /etc/apache2/sites-enabled/000-default.conf
Added this line after DocumentRoot /var/www/html
<Directory /var/www/html>
AllowOverride All
</Directory>
Restart your apache server
Note: /var/www/html will be your document root
This is BY FAR the easiest way to convert *.cer to *.pfx files:
Just download the portable certificate converter from DigiCert: https://www.digicert.com/util/pfx-certificate-management-utility-import-export-instructions.htm
Execute it, select a file and get your *.pfx!!
To vote on this issue, here is one active suggestion of how this could be added to the language. I'm not saying this is the best way to do this (at all), feel free to put out your own suggestion. But allowing properties to be passed by ref like Visual Basic already can do would hugely help simplify some code, and quite often!
In WPF it seems this code,
System.Windows.Forms.MessageBox.Show("Test");
is replaced with:
System.Windows.MessageBox.Show("Test");
The C standard (actually C99, I'm not up to date) says:
Alphabetic escape sequences representing nongraphic characters in the execution character set are intended to produce actions on display devices as follows:
\b
(backspace) Moves the active position to the previous position on the current line. [...]
\t
(horizontal tab) Moves the active position to the next horizontal tabulation position on the current line. [...]
Both just move the active position, neither are supposed to write any character on or over another character. To overwrite with a space you could try: puts("foo\b \tbar");
but note that on some display devices - say a daisy wheel printer - the o
will show the transparent space.
var results = list.GroupBy(x => x.Category)
.Select(g => g.OrderBy(x => x.SortByProp).FirstOrDefault());
For those wondering how to do this for groups that are not necessarily sorted correctly, here's an expansion of this answer that uses method syntax to customize the sort order of each group and hence get the desired record from each.
Note: If you're using LINQ-to-Entities you will get a runtime exception if you use First() instead of FirstOrDefault() here as the former can only be used as a final query operation.
$scope.clearSearch = function () {
$scope.searchAll = "";
};
JsFiddle of how you could do it without using inline JS.
As selected answer says you can use findAndModify to generate sequential IDs.
But I strongly disagree with opinion that you should not do that. It all depends on your business needs. Having 12-byte ID may be very resource consuming and cause significant scalability issues in future.
I have detailed answer here.
All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if
to bind them all together in the way I believe you intend.
The error as reported appears when the variables are null (or empty):
$ unset var3 var4; var5=$(($var4-$var3))
bash: -: syntax error: operand expected (error token is "-")
That could happen because the value given to bc was incorrect. That might well be that bc needs UPPERcase values. It needs BFCA3000
, not bfca3000
. That is easily fixed in bash, just use the ^^
expansion:
var3=bfca3000; var3=`echo "ibase=16; ${var1^^}" | bc`
That will change the script to this:
#!/bin/bash
var1="bfca3000"
var2="efca3250"
var3="$(echo "ibase=16; ${var1^^}" | bc)"
var4="$(echo "ibase=16; ${var2^^}" | bc)"
var5="$(($var4-$var3))"
echo "Diference $var5"
But there is no need to use bc [1], as bash could perform the translation and substraction directly:
#!/bin/bash
var1="bfca3000"
var2="efca3250"
var5="$(( 16#$var2 - 16#$var1 ))"
echo "Diference $var5"
[1]Note: I am assuming the values could be represented in 64 bit math, as the difference was calculated in bash in your original script. Bash is limited to integers less than ((2**63)-1) if compiled in 64 bits. That will be the only difference with bc which does not have such limit.
Set line-height
to the vertical size of the picture, then do vertical-align:middle
like Josh said.
so if the picture is 20px
, you would have
{
line-height:20px;
font-size:14px;
vertical-align:middle;
}
For <input type=number>
, by the HTML5 CR, the size
attribute is not allowed. However, in Obsolete features it says: “Authors should not, but may despite requirements to the contrary elsewhere in this specification, specify the maxlength and size attributes on input elements whose type attributes are in the Number state. One valid reason for using these attributes regardless is to help legacy user agents that do not support input elements with type="number" to still render the text field with a useful width.”
Thus, the size
attribute can be used, but it only affects older browsers that do not support type=number
, so that the element falls back to a simple text control, <input type=text>
.
The rationale behind this is that the browser is expected to provide a user interface that takes the other attributes into account, for good usability. As the implementations may vary, any size imposed by an author might mess things up. (This also applies to setting the width of the control in CSS.)
The conclusion is that you should use <input type=number>
in a more or less fluid setup that does not make any assumptions about the dimensions of the element.
Remember that char
is an integral type, and thus can be given an integer value, as well as a char constant.
char c = 0x2202;//aka 8706 in decimal. \u codepoints are in hex.
String s = String.valueOf(c);
Another advantage of CXF: it connects to web servers using NTLMV2 authentication out of the box. (used by Windows 2008 & up) Before using CXF, I hacked Axis2 to use HTTPClient V4 + JCIFS to make this possible.

Arguments
property in Execute Process Task available on the Control Flow tab is expecting a value of data type DT_WSTR
and not DT_STR
.
Create an SSIS package in Business Intelligence Development Studio (BIDS) 2008 R2 and name it as SO_13177007.dtsx
. Create a package variable with the following information.
Name Scope Data Type Value
------ ------------ ---------- -----
IdVar SO_13177007 Int32 123
Drag and drop an Execute Process Task onto the Control Flow tab and name it as Pass arguments
Double-click the Execute Process Task to open the Execute Process Task Editor
. Click Expressions page and then click the Ellipsis button against the Expressions property to view the Property Expression Editor
.
On the Property Expression Editor, select the property Arguments
and click the Ellipsis button against the property to open the Expression Builder
.
On the Expression Builder, enter the following expression and click Evaluate Expression
. This expression tries to convert the integer value in the variable IdVar
to string data type.
(DT_STR, 10, 1252) @[User::IdVar]
Clicking Evaluate Expression will display the following error message because the Arguments property on Execute Process Task expects a value of data type DT_WSTR
.
To fix the issue, update the expression as shown below to convert the integer value to data type DT_WSTR
. Clicking Evaluate Expression will display the value in the Evaluated value text area.
(DT_WSTR, 10) @[User::IdVar]
To understand the differences between the data types DT_STR
and DT_WSTR
in SSIS, read the documentation Integration Services Data Types on MSDN. Here are the quotes from the documentation about these two string data types.
A null-terminated ANSI/MBCS character string with a maximum length of 8000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)
A null-terminated Unicode character string with a maximum length of 4000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)
The ===
is not for checking string equalit , to do so you can use the Regxp functions for example
if (x.match(y) === null) {
// x and y are not equal
}
there is also the test
function
based on https://stackoverflow.com/a/19494006/1815624 and desire to make it happen...

Create a static value of the containers height before opening the keyboard
Set the container height based on usableHeightSansKeyboard - heightDifference
when the keyboard opens and set it back to the saved value when it closes
if (heightDifference > (usableHeightSansKeyboard / 4)) {
// keyboard probably just became visible
frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
int mStatusHeight = getStatusBarHeight();
frameLayoutParams.topMargin = mStatusHeight;
((MainActivity)activity).setMyMainHeight(usableHeightSansKeyboard - heightDifference);
if(BuildConfig.DEBUG){
Log.v("aBug5497", "keyboard probably just became visible");
}
} else {
// keyboard probably just became hidden
if(usableHeightPrevious != 0) {
frameLayoutParams.height = usableHeightSansKeyboard;
((MainActivity)activity).setMyMainHeight();
}
frameLayoutParams.topMargin = 0;
if(BuildConfig.DEBUG){
Log.v("aBug5497", "keyboard probably just became hidden");
}
}

public void setMyMainHeight(final int myMainHeight) {
runOnUiThread(new Runnable() {

similarly margins can be added if needed...
Another consideration is use padding an example of this can be found at:

Prototypes can be a hassle to work with, and from the _PROTO
part of the error it appears your error is caused by, say, HTMLCanvasElement.prototype.width
, possibly as an attempt to resize all the canvases at once.
As a suggestion, if you are trying to resize a number of canvases at once, you could try:
<canvas></canvas>
<canvas></canvas>
<canvas></canvas>
<script type="text/javascript">
...
</script>
In the JavaScript, instead of invoking a prototype, try this:
$$ = function(){
return document.querySelectorAll.apply(document,arguments);
}
for(var i in $$('canvas')){
canvas = $$('canvas')[i];
canvas.width = canvas.width+100;
canvas.height = canvas.height+100;
}
This would resize all the canvases by adding 100 px to their size, as is demonstrated in this example
I would use list comprehension :
somelists = [
[1, 2, 3],
['a', 'b'],
[4, 5]
]
cart_prod = [(a,b,c) for a in somelists[0] for b in somelists[1] for c in somelists[2]]
As others Mentioned, you can use the @SuppressFBWarnings
Annotation.
If you don't want or can't add another Dependency to your code, you can add the Annotation to your Code yourself, Findbugs dosn't care in which Package the Annotation is.
@Retention(RetentionPolicy.CLASS)
public @interface SuppressFBWarnings {
/**
* The set of FindBugs warnings that are to be suppressed in
* annotated element. The value can be a bug category, kind or pattern.
*
*/
String[] value() default {};
/**
* Optional documentation of the reason why the warning is suppressed
*/
String justification() default "";
}

A compiler specific difference between anonymous namespaces and static functions can be seen compiling the following code.
#include <iostream>
namespace
{
void unreferenced()
{
std::cout << "Unreferenced";
}
void referenced()
{
std::cout << "Referenced";
}
}
static void static_unreferenced()
{
std::cout << "Unreferenced";
}
static void static_referenced()
{
std::cout << "Referenced";
}
int main()
{
referenced();
static_referenced();
return 0;
}
Compiling this code with VS 2017 (specifying the level 4 warning flag /W4 to enable warning C4505: unreferenced local function has been removed) and gcc 4.9 with the -Wunused-function or -Wall flag shows that VS 2017 will only produce a warning for the unused static function. gcc 4.9 and higher, as well as clang 3.3 and higher, will produce warnings for the unreferenced function in the namespace and also a warning for the unused static function.
Use the onclick
as an attribute of your a

<a onclick='window.open("lead_data.php?leadid=1", myWin, scrollbars=yes, width=400, height=650);'>1</a>

To add multiple Lines in a configuration file you can use " "
instead of ' '
and escape sequence \n
for the new line in lineinfile
ansible module:
- name: Configure core-site.xml
lineinfile:
path: /etc/hadoop/core-site.xml
insertafter: '^<configuration>'
line: "Line 1 \n Line 2 \n Line 3"
A simpler but equally effective option would be:
+ theme_bw(base_size=X)
For these who don't get proper results other than mentioned languages, if you're using C# to print a text into console(terminal) window you should replace "\033" with "\x1b". In Visual Basic it would be Chrw(27).
Haven't tried it myself, but this page has a list of plugin modules that run in Linux' built in iptables IP filtering system. One of the modules is called "nth", and allows you to set up a rule that will drop a configurable rate of the packets. Might be a good place to start, at least.
PHP has a built-in function implode to assign array values to string. Use it like this:

For those of you who figured out that many/most of the ios::fmtflags
don't work with std::stringstream
yet like the template idea that Kornel posted way back when, the following works and is relatively clean:
#include <iomanip>
#include <sstream>
template< typename T >
std::string hexify(T i)
{
std::stringbuf buf;
std::ostream os(&buf);
os << "0x" << std::setfill('0') << std::setw(sizeof(T) * 2)
<< std::hex << i;
return buf.str().c_str();
}
int someNumber = 314159265;
std::string hexified = hexify< int >(someNumber);

It's rather very simple.
Consider the following Array
object.
var names: [String] = ["jack", "rose", "jill"]
In order to obtain the index of the element rose
, all you have to do is:
names.index(of: "rose") // returns 1
Note:
Array.index(of:)
returns an Optional<Int>
.
nil
implies that the element isn't present in the array.
You might want to force-unwrap the returned value or use an if-let
to get around the optional.
Use the CSS 3 property background-size
:

}

It lets you open WhatsApp conversation screen for that specific user you are trying to communicate with:

if (isWhatsappInstalled) {
Intent sendIntent = new Intent("android.intent.action.MAIN");

Just use the standard library in C++:
#include <bitset>
You need a variable of type std::bitset
:
std::bitset<8ul> x;
x = std::bitset<8>(10);
for (int i = x.size() - 1; i >= 0; i--) {
std::cout << x[i];
}
In this example, I stored the binary form of 10
in x
.
8ul
defines the size of your bits, so 7ul
means seven bits and so on.
you can do it as follow:
$("#addButton").click(function () {
if(counter>10){
alert("Only 10 textboxes allow");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
$("#removeButton").click(function () {
if(counter==1){
alert("No more textbox to remove");
return false;
}
counter--;
$("#TextBoxDiv" + counter).remove();
});

From javadocs
next() Returns the next token if it matches the pattern constructed from the specified string. nextLine() Advances this scanner past the current line and returns the input that was skipped.
Which one you choose depends which suits your needs best. If it were me reading a whole file I would go for nextLine until I had all the file.
From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)
The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.
In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.
raw_input()
takes exactly what the user typed and passes it back as a string.
input()
first takes the raw_input()
and then performs an eval()
on it as well.
The main difference is that input()
expects a syntactically correct python statement where raw_input()
does not.
raw_input()
was renamed to input()
so now input()
returns the exact string.input()
was removed. If you want to use the old input()
, meaning you need to evaluate a user input as a python statement, you have to do it manually by using eval(input())
.
datetime has fields hour
and minute
. So to get the hours and minutes, you would use t1.hour
and t1.minute
.
However, when you subtract two datetimes, the result is a timedelta, which only has the days
and seconds
fields. So you'll need to divide and multiply as necessary to get the numbers you need.

I would like to emphasize one comment from @Jules on this answer to this question. The comment brings a useful link: Spring Injection with @Resource, @Autowired and @Inject. I encourage you to read it entirely, however here is a quick summary of its usefulness:
@Autowired
and @Inject
@Resource
Explicitly name your component [@Component("beanName")]
Use @Resource
with the name
attribute [@Resource(name="beanName")]
@Qualifier
?Avoid @Qualifier
annotations unless you want to create a list of similar beans. For example you may want to mark a set of rules with a specific @Qualifier
annotation. This approach makes it simple to inject a group of rule classes into a list that can be used for processing data.
Scan specific packages for components [context:component-scan base-package="com.sourceallies.person"]
. While this will result in more component-scan
configurations it reduces the chance that you’ll add unnecessary components to your Spring context.
Reference: Spring Injection with @Resource, @Autowired and @Inject
you can show one line output then set property Line=0 and show multiple line output then set property Line=1 and more
[self.yourLableName sizeToFit];
Create a UITextView inside of a tableViewController. I used function: textViewDidChange and then checked for return-key-input. then if it detected return-key-input, delete the input of return key and dismiss keyboard.
func textViewDidChange(_ textView: UITextView) {
tableView.beginUpdates()
if textView.text.contains("\n"){
textView.text.remove(at: textView.text.index(before: textView.text.endIndex))
textView.resignFirstResponder()
}
tableView.endUpdates()
}
Trying http://0.0.0.0:3000/routes
on a Rails 5 API app (i.e.: JSON-only oriented) will (as of Rails beta 3) return

However, http://0.0.0.0:3000/rails/info/routes
will render a nice, simple HTML page with routes.
I also found leviathan's answer to work the best. However, it was calculating a strange height. When looping through the subviews, if the scrollview is set to show scroll indicators, those will be in the array of subviews. In this case, the solution is to temporarily disable the scroll indicators before looping, then re-establish their previous visibility setting.
-(void)adjustContentSizeToFit

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.
You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,
http://www.javaworld.com/javaworld/javatips/jw-javatip111.html
EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,
public SSLTunnelSocketFactory(String proxyhost, String proxyport){
tunnelHost = proxyhost;
tunnelPort = Integer.parseInt(proxyport);
dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
}
...
connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
connection.setDefaultHostnameVerifier( new HostnameVerifier()
{
public boolean verify( String arg0, SSLSession arg1 )
{
return true;
}
} );
EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,
http://bugs.sun.com/view_bug.do?bug_id=6614957
The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,
public class SSLContextTest {
public static void main(String[] args) {
System.setProperty("https.proxyHost", "proxy.xxx.com");
System.setProperty("https.proxyPort", "8888");
try {
SSLContext sslContext = SSLContext.getInstance("SSL");
// set up a TrustManager that trusts everything
sslContext.init(null, new TrustManager[] { new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
System.out.println("getAcceptedIssuers =============");
return null;
}
public void checkClientTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkClientTrusted =============");
}
public void checkServerTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkServerTrusted =============");
}
} }, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(
sslContext.getSocketFactory());
HttpsURLConnection
.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String arg0, SSLSession arg1) {
System.out.println("hostnameVerifier =============");
return true;
}
});
URL url = new URL("https://www.verisign.net");
URLConnection conn = url.openConnection();
BufferedReader reader =
new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
This is what I get when I run the program,
checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......
As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.
A checkbox has a linked cell, which contains the True/False representing the state of the checkbox. It is much easier to reference this cell's value than the value of the embedded object which is the checkbox.
Manually: Right click on the checkbox, choose Format, click in the Linked Cell box, and select the cell to contain the checkbox value.
In code:
Set cbTime = ActiveSheet.CheckBoxes.Add(100, 100, 50, 15)
With cbTime
.Value = xlOff ' = unchecked xlOn = checked
.LinkedCell = "$A$1"
End With
you can pass the json object as the body(third argument) of the fetch request.
I'm using GDB7.1.1, as --help
shows:
gdb [options] --args executable-file [inferior-arguments ...]
IMHO, the order is a bit unintuitive at first.
Ian put this in the comment, but I think it's a good answer:
if (exists("aVariable"))
{
do whatever
}
note that the variable name is quoted.
IE<=8 simply doesn't have an indexOf()
method for arrays.
If you need indexOf
in IE<=8, you should consider using the following polyfill, which is recommended at the MDN :
if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function(searchElement, fromIndex) {
var k;
if (this == null) {
throw new TypeError('"this" is null or not defined');
}
var o = Object(this);
var len = o.length >>> 0;
if (len === 0) {
return -1;
}
var n = +fromIndex || 0;
if (Math.abs(n) === Infinity) {
n = 0;
}
if (n >= len) {
return -1;
}
k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
while (k < len) {
if (k in o && o[k] === searchElement) {
return k;
}
k++;
}
return -1;
};
}
Minified :
Array.prototype.indexOf||(Array.prototype.indexOf=function(r,t){var n;if(null==this)throw new TypeError('"this" is null or not defined');var e=Object(this),i=e.length>>>0;if(0===i)return-1;var a=+t||0;if(Math.abs(a)===1/0&&(a=0),a>=i)return-1;for(n=Math.max(a>=0?a:i-Math.abs(a),0);i>n;){if(n in e&&e[n]===r)return n;n++}return-1});
No, there is no such type. But there are some choices:
None of these are really elegant, but that's the best there is.
If you are using windows and are interested in clearing the screen before running the program, you can compile the file call it from a .bat file. for example:
cls
java "what ever the name of the compiles class is"
Save as "etc".bat and then running by calling it in the command prompt or double clicking the file
Just install http-server globally
npm install -g http-server
where ever you need to run a html file run the command http-server
For ex: your html file is in /home/project/index.html
you can do /home/project/$ http-server
That will give you a link to accessyour webpages:
http-server
Starting up http-server, serving ./
Available on:
http://127.0.0.1:8080
http://192.168.0.106:8080
public void schedule(TimerTask task,long delay)
Schedules the specified task for execution after the specified delay.
you want:
public void schedule(TimerTask task, long delay, long period)
Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.

Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
Sometimes changing document.body.innerHTML
breaks some JS scripts on page. Here is version, that only changes content of text
elements:
function replace(element, from, to) {
if (element.childNodes.length) {
element.childNodes.forEach(child => replace(child, from, to));
} else {
const cont = element.textContent;
if (cont) element.textContent = cont.replace(from, to);
}
};
replace(document.body, new RegExp("hello", "g"), "hi");
According MDN documentation:
A Map object iterates its elements in insertion order.
You could do it this way:
var map = new Map();
map.set('2-1', "foo");
map.set('0-1', "bar");
map.set('3-1', "baz");
var mapAsc = new Map([...map.entries()].sort());
console.log(mapAsc)
_x000D_
Using .sort()
, remember that the array is sorted according to each character's Unicode code point value, according to the string conversion of each element. So 2-1, 0-1, 3-1
will be sorted correctly.
The Self-Host now uses Owin. Checkout http://www.asp.net/signalr/overview/signalr-20/getting-started-with-signalr-20/tutorial-signalr-20-self-host to setup the server. It's compatible with the client code above.
If you are in IE11, you can tell IE to always refresh from the server for a specific browsing session with IE Developer Tools.
(Sorry for french capture)
Old thread, but just came across this in a sample:
services.AddSignalR()
.AddAzureSignalR(options =>
{
options.ClaimsProvider = context => new[]
{
new Claim(ClaimTypes.NameIdentifier, context.Request.Query["username"])
};
});
How about just using associative arrays?
function intersect(a, b) {
var d1 = {};
var d2 = {};
var results = [];
for (var i = 0; i < a.length; i++) {
d1[a[i]] = true;
}
for (var j = 0; j < b.length; j++) {
d2[b[j]] = true;
}
for (var k in d1) {
if (d2[k])
results.push(k);
}
return results;
}
edit:
// new version
function intersect(a, b) {
var d = {};
var results = [];
for (var i = 0; i < b.length; i++) {
d[b[i]] = true;
}
for (var j = 0; j < a.length; j++) {
if (d[a[j]])
results.push(a[j]);
}
return results;
}
You can add full text to an existing instance by changing the SQL Server program in Programs and Features. Follow the steps below. You might need the original disk or ISO for the installation to complete. (Per HotN's comment: If you have SQL Server Express, make sure it is SQL Server Express With Advanced Services.)
Directions:
On the Installation Type screen, select the appropriate SQL Server instance.
Advance through the rest of the wizard.

There's no difference in internal representation between 2 and 2.00. You can use Math.round
to round a value to the nearest integer - to make that round to 2 decimal places you could multiply by 100, round, and then divide by 100, but you shouldn't expect the result to be exactly 2dps, due to the nature of binary floating point arithmetic.
If you're only interested in formatting a value to two decimal places, look at DecimalFormat
- if you're interested in a number of decimal places while calculating you should really be using BigDecimal
. That way you'll know that you really are dealing with decimal digits, rather than "the nearest available double
value".
Another option you may want to consider if you're always dealing with two decimal places is to store the value as a long
or BigInteger
, knowing that it's exactly 100 times the "real" value - effectively storing cents instead of dollars, for example.
Windows uses backward slashes, linux uses forward slashes.
I got here with an MS Access problem.
Backticks are good for MySQL, but they create weird errors, like "Invalid Query Name: Query1" in MS Access, for MS Access only, use square brackets:
It should look like this
SELECT Customer.[Customer ID], Customer.[Full Name] ...
I think your example is a sensible approach, although you could simplify it slightly as:
@title = tokens[Title].strip! || tokens[Title] if tokens[Title]
Alternative you could put it on two lines:
@title = tokens[Title] || ''
@title.strip!
If you want to read space separated string, and immediately split the string into an array, you can do this:
var arr = readLine()!.characters.split(" ").map(String.init)
eg.
print("What is your full name?")
var arr = readLine()!.characters.split(" ").map(String.init)
var firstName = ""
var middleName = ""
var lastName = ""
if arr.count > 0 {
firstName = arr[0]
}
if arr.count > 2 {
middleName = arr[1]
lastName = arr[2]
} else if arr.count > 1 {
lastName = arr[1]
}
print("First Name: \(firstName)")
print("Middle Name: \(middleName)")
print("Last Name: \(lastName)")
<?php
function takes_array($input)
{
echo "$input[0] + $input[1] = ", $input[0]+$input[1];
}
?>
Yeah Got it...
Date dob=null;
DateFormat df=new SimpleDateFormat("dd/MM/yyyy");
dob=df.parse( "13/06/1983" );
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(dob);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), DatatypeConstants.FIELD_UNDEFINED);
This will give it in correct format.
Amazed this hasn't been noted so far, but it is common sense to use var
for foreach
loop variables.
If you specify a specific type instead, you risk having a runtime cast silently inserted into your program by the compiler!
foreach (Derived d in listOfBase)
{
The above will compile. But the compiler inserts a downcast from Base
to Derived
. So if anything on the list is not a Derived
at runtime, there is an invalid cast exception. Type safety is compromised. Invisible casts are horrible.
The only way to rule this out is to use var
, so the compiler determines the type of the loop variable from the static type of the list.
Maybe a bit late, but: instead of this:
public void onNewIntent(Intent intent){
Bundle extras = intent.getExtras();
Log.i( "dbg","onNewIntent");
if(extras != null){
Log.i( "dbg", "Extra6 bool: "+ extras.containsKey("net.dbg.android.fjol"));
Log.i( "dbg", "Extra6 val : "+ extras.getString("net.dbg.android.fjol"));
}
mTabsController.setActiveTab(TabsController.TAB_DOWNLOADS);
}
Use this:
Bundle extras = getIntent().getExtras();
if(extras !=null) {
String value = extras.getString("keyName");
}
I use combination of several plugins - for the basic assignment of roles and permission I use Role Strategy Plugin.
When I need to split some role depending on parameters (e.g. everybody with job-runner is able to run jobs, but user only user UUU is allowed to run the deployment job to deploy on machine MMM), I use Python Plugin and define a python script as first build step and end with sys.exit(-1) when the job is forbidden to be run with the given combination of parameters.
Build User Vars Plugin provides me the information about the user executing the job as environment variables.
E.g:
import os
import sys
print os.environ["BUILD_USER"], "deploying to", os.environ["target_host"]
# only some users are allowed to deploy to servers "MMM"
mmm_users = ["UUU"]
if os.environ["target_host"] != "MMM" or os.environ["BUILD_USER"] in mmm_users:
print "access granted"
else:
print "access denied"
sys.exit(-1)
You can use typeof(N)
to get the actual object type, but what you want to do is check the tag, not the type of the DOM element.
In that case, use the elem.tagName
or elem.nodeName
property.
if you want to get really creative, you can use a dictionary of tagnames and anonymous closures instead if a switch or if/else.
I don't think you can achieve that with mysql date. You have to use timestamp or try this approach..
CREATE TRIGGER table_OnInsert BEFORE INSERT ON `DB`.`table`
FOR EACH ROW SET NEW.dateColumn = IFNULL(NEW.dateColumn, NOW());
This is an ancient question, but both module private (one underscore) and class-private (two underscores) mangled variables are now covered in the standard documentation:
Image by default is displayed as inline-block, you need to display it as block in order to center it with .mx-auto
. This can be done with built-in .d-block
:
<div class="container">
<div class="row">
<div class="col-4">
<img class="mx-auto d-block" src="...">
</div>
</div>
</div>
Or leave it as inline-block and wrapped it in a div with .text-center
:
<div class="container">
<div class="row">
<div class="col-4">
<div class="text-center">
<img src="...">
</div>
</div>
</div>
</div>
I made a fiddle showing both ways. They are documented here as well.
var myCallback = function(data) {
console.log('got data: '+data);
};
var usingItNow = function(callback) {
callback('get it?');
};
Now open node or browser console and paste the above definitions.
Finally use it with this next line:
usingItNow(myCallback);
With Respect to the Node-Style Error Conventions
Costa asked what this would look like if we were to honor the node error callback conventions.
In this convention, the callback should expect to receive at least one argument, the first argument, as an error. Optionally we will have one or more additional arguments, depending on the context. In this case, the context is our above example.
Here I rewrite our example in this convention.
var myCallback = function(err, data) {
if (err) throw err; // Check for the error and throw if it exists.
console.log('got data: '+data); // Otherwise proceed as usual.
};
var usingItNow = function(callback) {
callback(null, 'get it?'); // I dont want to throw an error, so I pass null for the error argument
};
If we want to simulate an error case, we can define usingItNow like this
var usingItNow = function(callback) {
var myError = new Error('My custom error!');
callback(myError, 'get it?'); // I send my error as the first argument.
};
The final usage is exactly the same as in above:
usingItNow(myCallback);
The only difference in behavior would be contingent on which version of usingItNow
you've defined: the one that feeds a "truthy value" (an Error object) to the callback for the first argument, or the one that feeds it null for the error argument.
Using the data.table
package, which is fast (useful for larger datasets)
https://github.com/Rdatatable/data.table/wiki
library(data.table)
df2 <- setDT(df1)[, lapply(.SD, sum), by=.(year, month), .SDcols=c("x1","x2")]
setDF(df2) # convert back to dataframe
Using the plyr package
require(plyr)
df2 <- ddply(df1, c("year", "month"), function(x) colSums(x[c("x1", "x2")]))
Using summarize() from the Hmisc package (column headings are messy in my example though)
# need to detach plyr because plyr and Hmisc both have a summarize()
detach(package:plyr)
require(Hmisc)
df2 <- with(df1, summarize( cbind(x1, x2), by=llist(year, month), FUN=colSums))
There are two points I want to make about yield here. First, while a lot of answers here talk about different ways to pass a block to a method which uses yield, let's also talk about the control flow. This is especially relevant since you can yield MULTIPLE times to a block. Let's take a look at an example:
class Fruit
attr_accessor :kinds
def initialize
@kinds = %w(orange apple pear banana)
end
def each
puts 'inside each'
3.times { yield (@kinds.tap {|kinds| puts "selecting from #{kinds}"} ).sample }
end
end
f = Fruit.new
f.each do |kind|
puts 'inside block'
end
=> inside each
=> selecting from ["orange", "apple", "pear", "banana"]
=> inside block
=> selecting from ["orange", "apple", "pear", "banana"]
=> inside block
=> selecting from ["orange", "apple", "pear", "banana"]
=> inside block
When the each method is invoked, it executes line by line. Now when we get to the 3.times block, this block will be invoked 3 times. Each time it invokes yield. That yield is linked to the block associated with the method that called the each method. It is important to notice that each time yield is invoked, it returns control back to the block of the each method in client code. Once the block is finished executing, it returns back to the 3.times block. And this happens 3 times. So that block in client code is invoked on 3 separate occasions since yield is explicitly called 3 separate times.
My second point is about enum_for and yield. enum_for instantiates the Enumerator class and this Enumerator object also responds to yield.
class Fruit
def initialize
@kinds = %w(orange apple)
end
def kinds
yield @kinds.shift
yield @kinds.shift
end
end
f = Fruit.new
enum = f.to_enum(:kinds)
enum.next
=> "orange"
enum.next
=> "apple"
So notice every time we invoke kinds with the external iterator, it will invoke yield only once. The next time we call it, it will invoke the next yield and so on.
There's an interesting tidbit with regards to enum_for. The documentation online states the following:
enum_for(method = :each, *args) ? enum
Creates a new Enumerator which will enumerate by calling method on obj, passing args if any.
str = "xyz"
enum = str.enum_for(:each_byte)
enum.each { |b| puts b }
# => 120
# => 121
# => 122
If you do not specify a symbol as an argument to enum_for, ruby will hook the enumerator to the receiver's each method. Some classes do not have an each method, like the String class.
str = "I like fruit"
enum = str.to_enum
enum.next
=> NoMethodError: undefined method `each' for "I like fruit":String
Thus, in the case of some objects invoked with enum_for, you must be explicit as to what your enumerating method will be.
Seems to work
$(".selector").change(function() {
var $value = $(this).val();
var $title = $(this).children('option[value='+$value+']').html();
$('#bacon').val($title);
});
Just check with your firebug. And don't put css on hidden input.
Git has a fairly complete set of traces embedded which you can use to debug your git problems.
To turn them on, you can define the following variables:
GIT_TRACE
for general traces,GIT_TRACE_PACK_ACCESS
for tracing of packfile access,GIT_TRACE_PACKET
for packet-level tracing for network operations,GIT_TRACE_PERFORMANCE
for logging the performance data,GIT_TRACE_SETUP
for information about discovering the repository and environment it’s interacting with,GIT_MERGE_VERBOSITY
for debugging recursive merge strategy (values: 0-5),GIT_CURL_VERBOSE
for logging all curl messages (equivalent to curl -v
),GIT_TRACE_SHALLOW
for debugging fetching/cloning of shallow repositories.Possible values can include:
true
, 1
or 2
to write to stderr,/
to trace output to the specified file.For more details, see: Git Internals - Environment Variables
For SSH issues, try the following commands:
echo 'ssh -vvv "$*"' > ssh && chmod +x ssh
GIT_SSH="$PWD/ssh" git pull origin master
or use ssh
to validate your credentials, e.g.
ssh -vvvT [email protected]
or over HTTPS port:
ssh -vvvT -p 443 [email protected]
Note: Reduce number of -v
to reduce the verbosity level.

You need to create a git repo locally, add your project files to that repo, commit them to the local repo, and then sync that repo to your repo on github. You can find good instructions on how to do the latter bit on github, and the former should be easy to do with the software you've downloaded.
If I remember correctly, the gen stands for generation, as in a generational garbage collector (that treats younger objects differently than mid-life and "permanent" objects). Principle of locality suggests that recently created objects will be wiped out first.
If you are using it on CentOS,you may need to reload postgres after making the above solutions:
systemctl restart postgresql-9.3.service
Accepted answer is correct, but I like to define this little utility in most projects I build.
var types = {
'get': function(prop) {
return Object.prototype.toString.call(prop);
},
'null': '[object Null]',
'object': '[object Object]',
'array': '[object Array]',
'string': '[object String]',
'boolean': '[object Boolean]',
'number': '[object Number]',
'date': '[object Date]',
}
Used like this:
if(types.get(prop) == types.number) {
}
If you're using angular you can even have it cleanly injected:
angular.constant('types', types);
Instruction is base on the "icemelon" post. Link to the post:
how-do-i-compile-and-run-a-c-program-in-sublime-text-2
Use the link below to find out how to setup enviroment variable on your OS:
The instruction below was tested on the Windows 8.1 system and Sublime Text 3 - build 3065.
1) Install MinGW. 2) Add path to the "MinGW\bin" in the "PATH environment variable".
"System Properties -> Advanced -> Environment" variables and there update "PATH' variable.
3) Then check your PATH environment variable by the command below in the "Command Prompt":
echo %path%
4) Add new Build System to the Sublime Text.
My version of the code below ("C.sublime-build").
link to the code:
// Put this file here:
// "C:\Users\[User Name]\AppData\Roaming\Sublime Text 3\Packages\User"
// Use "Ctrl+B" to Build and "Crtl+Shift+B" to Run the project.
// OR use "Tools -> Build System -> New Build System..." and put the code there.
{
"cmd" : ["gcc", "$file_name", "-o", "${file_base_name}.exe"],

Actually you can do with VS Code the following:
libsysfs does look potentially useful, but not directly from a shell script. There's a program that comes with it called systool which will do what you want, though it may be easier to just look in /sys directly rather than using another program to do it for you.
Hashtags at the end of the URL bring a visitor to the element with the ID: e.g.
http://stackoverflow.com/questions/8424785/link-to-a-section-of-a-webpage#answers
Would bring you to where the DIV with the ID 'answers' begins. Also, you can use the name attribute in anchor tags, to create the same effect.
Come on guys, there is no need to loop, just use simple math to solve this equation system:
a*b = i;
a+b = j;
a = j/b;
a = i-b;
j/b = i-b; so:
b + j/b + i = 0
b^2 + i*b + j = 0
From here, its a quadratic equation, and it's trivial to find b (just implement the quadratic equation formula) and from there get the value for a.
EDIT:
There you go:
function finder($add,$product)
{
$inside_root = $add*$add - 4*$product;
if($inside_root >=0)
{
$b = ($add + sqrt($inside_root))/2;
$a = $add - $b;
echo "$a+$b = $add and $a*$b=$product\n";
}else
{
echo "No real solution\n";
}
}
Real live action:
Just code, with implementation of GetHashCode
and NULL
validation:
public class Class_reglementComparer : IEqualityComparer<Class_reglement>
{
public bool Equals(Class_reglement x, Class_reglement y)
{
if (x is null || y is null))
return false;
return x.Numf == y.Numf;
}
public int GetHashCode(Class_reglement product)
{
//Check whether the object is null
if (product is null) return 0;
//Get hash code for the Numf field if it is not null.
int hashNumf = product.hashNumf == null ? 0 : product.hashNumf.GetHashCode();
return hashNumf;
}
}
Example: list of Class_reglement distinct by Numf
List<Class_reglement> items = items.Distinct(new Class_reglementComparer());
I wrote a tutorial about this a while ago.
The most important point is the "Site URL":
Site URL: http://localhost/app_name/
Where the folder structure is something like:

¦ +---css
¦ main.css
¦ reset.css
¦
+---src
facebook.php
fb_ca_chain_bundle.crt
EDIT:
Kavya: how does the FB server recognize my localhost even without an IP or port??
I don't think this has anything to do with Facebook, I guess since the iframe src
parameter is loaded from client-side it'll treat your local URL as if you put it directly on your browser.
For example have a file on your online server with content (e.g. online.php
):
<iframe src="http://localhost/test.php" width="100%" height="100%">
<p>Not supported!</p>
</iframe>
And on your localhost root directory, have the file test.php
:
<?php echo "Hello from Localhost!"; ?>
Now visit http://your_domain.com/online.php
you will see your localhost file's content!
This is why realtime subscriptions and deauthorize callbacks (just to mention) won't work with localhost URLs! because Facebook will ping (send http requests) to these URLs but obviously Facebook server won't translate those URLs to yours!
class name:
def __init__(self, name):

Somewhere else:
john = name("john")
Output:

Well, I'm not sure if my solution is best practice. Using the NotificationBuilder
my code looks like that:
private void showNotification() {
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(
this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIntent);

Came across the question myself today. I think the reason that your code returns 'None' (exactly what I got by using the same method) is that
a.sort()
is calling the sort function to mutate the list a. In my understanding, this is a modification command. To see the result you have to use print(a).
My solution, as I tried to keep everything in pandas:
pd.Series(df['A'].unique()).sort_values()
A fun, but useless way to do this:
az = ('a'..'z').to_a
azz = az.map{|e| [e, az.index(e)+2]}
Use the command
git clone --help
to see whether your git supports the command
git clone --branch tag_name
If not, just do the following:
git clone repo_url
cd repo
git checkout tag_name
Like this :
String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
List<String> wordList = new ArrayList<String>(Arrays.asList(words));
or
List myList = new ArrayList();
String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
Collections.addAll(myList, words);
For me it was a fresh NetCore application that was just not loading via IIS. When run standalone it was OK though.
I removed the <aspNetCore
line and then I got a normal error message from IIS saying that NetCoreModule could not be loaded. That module is required to understand this new web.config line.
The error message 0x8007000d
actually says that the web.config is malformed and that error shows up before the error loading module making this error message really crap. (and an unfortunate race condition problem)
I installed the NetCoreSDK and stopped and started IIS (restart didnt work)
The NetCore API started working via IIS as expected.

There are a number of work-flows you can use. The main point is not to break history in a published branch unless you've communicated with everyone who might consume the branch and are willing to do surgery on everyone's clones. It's best not to do that if you can avoid it.
Your outlined steps have merit. If you need the dev branch to be stable right away, do it that way. You have a number of tools for Debugging with Git that will help you find the right branch point, and then you can revert all the commits between your last stable commit and HEAD.
Either revert commits one at a time, in reverse order, or use the <first_bad_commit>..<last_bad_commit>
range. Hashes are the simplest way to specify the commit range, but there are other notations. For example, if you've pushed 5 bad commits, you could revert them with:
# Revert a series using ancestor notation.
git revert --no-edit dev~5..dev
# Revert a series using commit hashes.
git revert --no-edit ffffffff..12345678
This will apply reversed patches to your working directory in sequence, working backwards towards your known-good commit. With the --no-edit flag, the changes to your working directory will be automatically committed after each reversed patch is applied.
See man 1 git-revert
for more options, and man 7 gitrevisions
for different ways to specify the commits to be reverted.
Alternatively, you can branch off your HEAD, fix things the way they need to be, and re-merge. Your build will be broken in the meantime, but this may make sense in some situations.
Of course, if you're absolutely sure that no one has pulled from the repository since your bad pushes, and if the remote is a bare repository, then you can do a non-fast-forward commit.
git reset --hard <last_good_commit>
git push --force
This will leave the reflog intact on your system and the upstream host, but your bad commits will disappear from the directly-accessible history and won't propagate on pulls. Your old changes will hang around until the repositories are pruned, but only Git ninjas will be able to see or recover the commits you made by mistake.
Most likely the remote repository doesn't exist or you have added the wrong one.
You have to first remove the origin and re-add it:
git remote remove origin
git remote add origin https://github.com/username/repository

Check out printf...

Without using printf
echo -e $mystr
Output: say "hi"
Using printf
echo -e $(printf '%q' $mystr)
Output: say \"hi\"
You can simply try this and it should work in most cases, feel free to correct me if I am wrong :

if(obj.val() != "") {
//Do this here

If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/
It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates
Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/
There are some SPARQL libraries available for multiple platforms to make queries easier

@tasseKATT's Answer is great, but if you don't want to make a directive, why not use $document
?
.controller('ExampleController', ['$scope', '$document', function($scope, $document) {
var dumb = function (id) {
var queryResult = $document[0].getElementById(id)
var wrappedID = angular.element(queryResult);
return wrappedID;
};

In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager
then find Xml Tools
plugin. Tick the box and click Install
Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now
).
Following dialog will open:
Click on ...
. Point to XSD file and I am pretty sure you'll be able to handle things from here.
Hope this saves you some time.
EDIT:
Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1
plugin manager is back under a different guise... Plugin Admin
so now you can simply update notepad++ and have it back.
If you want to insert text inside your EditText view that stays there after the field is selected (unlike how hint behaves), do this:
In Java:
// Cast Your EditText as a TextView
((TextView) findViewById(R.id.email)).setText("your Text")
In Kotlin:
// Cast your EditText into a TextView
// Like this
(findViewById(R.id.email) as TextView).text = "Your Text"
// Or simply like this
findViewById<TextView>(R.id.email).text = "Your Text"
A debugging script (jquery solution based on the answer above by hashchange)
function getAttributes ( $node ) {
$.each( $node[0].attributes, function ( index, attribute ) {
console.log(attribute.name+':'+attribute.value);
} );
}
getAttributes($(this)); // find out what attributes are available
You can use
<%
Response.Write("Version: " + System.Environment.Version.ToString());
%>
That will get the currently running version. You can check the registry for all installed versions at:

Just to correct mingos' answer:
If you set the expiration time to 0, the cookie won't be created at all. I've tested this on Google Chrome at least, and when set to 0 that was the result. The cookie, I guess, expires immediately after creation.
To set a cookie so it expires at the end of the browsing session, simply OMIT the expiration parameter altogether.
Example:
Instead of:
document.cookie = "cookie_name=cookie_value; 0; path=/";
Just write:
document.cookie = "cookie_name=cookie_value; path=/";

This is a handshake failure. The other side closes the connection without sending any data ("read 0 bytes"). It might be, that the other side does not speak SSL at all. But I've seen similar errors on broken SSL implementation, which do not understand newer SSL version. Try if you get a SSL connection by adding -ssl3

Interestingly enough I tried both of these in LinqPad and the variant using group from Dmitry Gribkov by appears to be quicker. (also the final distinct is not required as the result is already distinct.
My (somewhat simple) code was:
public class Pair
{
public int id {get;set;}
public string Arb {get;set;}
}
void Main()
{
var theList = new List<Pair>();
var randomiser = new Random();
for (int count = 1; count < 10000; count++)
{
theList.Add(new Pair
{
id = randomiser.Next(1, 50),
Arb = "not used"
});
}
var timer = new Stopwatch();
timer.Start();
var distinct = theList.GroupBy(c => c.id).Select(p => p.First().id);
timer.Stop();
Debug.WriteLine(timer.Elapsed);
timer.Start();
var otherDistinct = theList.Select(p => p.id).Distinct();
timer.Stop();
Debug.WriteLine(timer.Elapsed);
}

You can access session variables from any page or control using Session["loginId"]
and from any class (e.g. from inside a class library), using System.Web.HttpContext.Current.Session["loginId"].
But please read on for my original answer...
I always use a wrapper class around the ASP.NET session to simplify access to session variables:
public class MySession
{
// private constructor
private MySession()
{
Property1 = "default value";
}
// Gets the current session.
public static MySession Current
{
get
{
MySession session =
(MySession)HttpContext.Current.Session["__MySession__"];
if (session == null)
{
session = new MySession();
HttpContext.Current.Session["__MySession__"] = session;
}
return session;
}
}
// **** add your session properties here, e.g like this:
public string Property1 { get; set; }
public DateTime MyDate { get; set; }
public int LoginId { get; set; }
}
This class stores one instance of itself in the ASP.NET session and allows you to access your session properties in a type-safe way from any class, e.g like this:
int loginId = MySession.Current.LoginId;
string property1 = MySession.Current.Property1;
MySession.Current.Property1 = newValue;
DateTime myDate = MySession.Current.MyDate;
MySession.Current.MyDate = DateTime.Now;
This approach has several advantages:
If you just want to change alignment of text just make a classes
.left {
text-align: left;
}
and span that class through the text
<span class='left'>aligned left</span>
If you select two files in IntellijIdea and press Ctrl + D

Somewhere in your code there is a line #include <string>
. This by itself tells you that the program is written in C++. So using g++
is better than gcc
.
For the missing library: you should look around in the file system if you can find a file called libl.so
. Use the locate
command, try /usr/lib
, /usr/local/lib
, /opt/flex/lib
, or use the brute-force find / | grep /libl
.
Once you have found the file, you have to add the directory to the compiler command line, for example:
g++ -o scan lex.yy.c -L/opt/flex/lib -ll
Unfortunately, no. This feature is not available for facebook albums.

Echo The name of this scriptfile %~n0
Echo The extension of this scriptfile %~x0
Echo.
If "%~2"=="" (

There is another option to scroll page to required element if element has "id"
attribute
If you want to navigate to page and scroll down to element with @id
, it can be done automatically by adding #element_id
to URL...
Example
Let's say we need to navigate to Selenium Waits documentation and scroll page down to "Implicit Wait" section. We can do
driver.get('https://selenium-python.readthedocs.io/waits.html')
and add code for scrolling...OR use
driver.get('https://selenium-python.readthedocs.io/waits.html#implicit-waits')
to navigate to page AND scroll page automatically to element with id="implicit-waits"
(<div class="section" id="implicit-waits">...</div>
)
You could try doing
document.getElementById(id).innerHTML = ajax_response
In later Elasticsearch versions (7.x), types were removed. Updating a mapping can becomes:
curl -XPUT "http://localhost:9200/test/_mapping" -H 'Content-Type: application/json' -d'{
"properties": {
"new_geo_field": {
"type": "geo_point"
}
}
}'
As others have pointed out, if the field exists, you typically have to reindex. There are exceptions, such as adding a new sub-field or changing analysis settings.
You can't "create a mapping", as the mapping is created with the index. Typically, you'd define the mapping when creating the index (or via index templates):
curl -XPUT "http://localhost:9200/test" -H 'Content-Type: application/json' -d'{
"mappings": {
"properties": {
"foo_field": {
"type": "text"
}
}
}
}'
That's because, in production at least, you'd want to avoid letting Elasticsearch "guess" new fields. Which is what generated this question: geo data was read as an array of long
values.
It's too late to answer this question, but it could help for new readers,
It seems version issues. I ran all these tests with spring 4.1.4 and found that the order of @RequestBody
and @RequestParam
doesn't matter.
body= "name=abc"
, and name = "abc"
body ="name=abc"
, name = "xyz,abc"
Another useful way is with Concat.
More information in the official documentation.
List<string> first = new List<string> { "One", "Two", "Three" };
List<string> second = new List<string>() { "Four", "Five" };
first.Concat(second);
The output will be.
One
Two
Three
Four
Five
And there is another similar answer.
I had trouble finding the applicationhost.config file. It was in c:\windows\System32\inetsrv\ (Server2008) or the c:\windows\System32\inetsrv\config\ (Server2008r2).
After I changed that setting, I also had to change the way IIS loads the aspnet_filter.dll. Open the IIS Manager, go under "Sites", "SharePoint - 80", in the "IIS" grouping, under the "ISAPI Filters", make sure that all of the "Executable" paths point to ...Microsoft.NET\Framework64\v#.#.####\aspnet_filter.dll. Some of mine were pointed to the \Framework\ (not 64).
You also need to restart the WWW service to reload the new settings.
app.use(express.favicon(__dirname + '/public/images/favicon.ico'));
I had it working locally without the __dirname +
but couldn't get it working on my deployed server.
You can do that using the SimpleDateFormat
class.
SimpleDateFormat formatter=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String dates=formatter.format(mydate);
//mydate is your date object

I faced the same problem whenever i am firing SELECT query with specific columns, though the one of the column is primary in table. I was trying to fetch selective records with selective columns in standard wordpress "posts" table. ID column is already primary and unique..
Just specifying primary/unique column name will not resolve this issue. You have to specify full column name like "posts.id" (tablename.columnname) that tells PMA to select specific column and reveals edit etc..
My PMA is 4.3.8. Let me know if this helps..
fn
literally refers to the jquery prototype
.
This line of code is in the source code:
jQuery.fn = jQuery.prototype = {
//list of functions available to the jQuery api
}
But the real tool behind fn
is its availability to hook your own functionality into jQuery. Remember that jquery will be the parent scope to your function, so this
will refer to the jquery object.
$.fn.myExtension = function(){
var currentjQueryObject = this;
//work with currentObject
return this;//you can include this if you would like to support chaining
};
So here is a simple example of that. Lets say I want to make two extensions, one which puts a blue border, and which colors the text blue, and I want them chained.
jsFiddle Demo
$.fn.blueBorder = function(){
this.each(function(){
$(this).css("border","solid blue 2px");
});
return this;
};
$.fn.blueText = function(){
this.each(function(){
$(this).css("color","blue");
});
return this;
};
Now you can use those against a class like this:
$('.blue').blueBorder().blueText();
(I know this is best done with css such as applying different class names, but please keep in mind this is just a demo to show the concept)
This answer has a good example of a full fledged extension.
If you have an image imported as a resource in your project there is also this:
picPreview.Image = Properties.Resources.ImageName;
Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.
*Resources are located by going to: Project --> Properties --> Resources
Are you trying to actually follow the link or trigger the onclick? You can trigger an onclick with something like this:
var link = document.getElementById(linkId);
link.onclick.call(link);
Navigate to Window > Preferences > General > Editors > Text Editors
Click on the CheckBox "Show whitespace characters".
Thats all.!!!
If this code fails to operate on every item in the list, it must be because something is throwing an exception before you have completed the list; the likeliest candidate is the method called "insertOrThrow". You could wrap that call in a try-catch structure to handle the exception for whichever items are failing without exiting the loop and the method prematurely.

template_name = 'manager/add_product.html'

sub_form = ImageForm(self.request.GET or None, prefix="loc")

context['form'] = form
context['sub_form'] = sub_form
return self.render_to_response(context)

sub_form = ImageForm(request.POST, prefix="loc")

I know it's late but, you could use a wrapper to your buttons and change a rgba color function opacity level, as said in other answers but with no explicit example.

I've had this issue on a Mac - while I setup SSH correctly to access my Git repository, after restart (and some time the Mac was on a standoff), all my credentials were removed. Apparently, for some reason the pub key was set to 644 which caused it to be removed from the keychain. To readd:
chmod 600
the public keyssh-add ~/.ssh/[your private key]
- this should display that identity has been added. The key file you want is the one without the .pub extension.ssh-add -l
should show you newly added identityedit: apparently MacOS has tendency of removing keys - after downloading the High Sierra update (but I've not installed it yet) my key has been removed and I've had to add it again via ssh-add
Both have similar functionality only difference is that fill_parent is used up to API level 8 and match_parent is used after API level 8 or higher level.
For just reading file and outputting it the best one would be readfile
.
what you could do, is put an if statement around everything inside the loop that you want kept away from the 50. e.g.
for i in range(0, len(list)):
if i != 50:
x= listRow(list, i)
for j in range (#0 to len(list) not including x#)
I had an issue with the parseActivityForResult arguments. I got this to work:
package JMA.BarCodeScanner;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class JMABarcodeScannerActivity extends Activity {
Button captureButton;
TextView tvContents;
TextView tvFormat;
Activity activity;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
activity = this;
captureButton = (Button)findViewById(R.id.capture);
captureButton.setOnClickListener(listener);
tvContents = (TextView)findViewById(R.id.tvContents);
tvFormat = (TextView)findViewById(R.id.tvFormat);
}
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
switch (requestCode)
{
case IntentIntegrator.REQUEST_CODE:
if (resultCode == Activity.RESULT_OK)
{
IntentResult intentResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (intentResult != null)
{
String contents = intentResult.getContents();
String format = intentResult.getFormatName();
tvContents.setText(contents.toString());
tvFormat.setText(format.toString());
//this.elemQuery.setText(contents);
//this.resume = false;
Log.d("SEARCH_EAN", "OK, EAN: " + contents + ", FORMAT: " + format);
} else {
Log.e("SEARCH_EAN", "IntentResult je NULL!");
}
}
else if (resultCode == Activity.RESULT_CANCELED) {
Log.e("SEARCH_EAN", "CANCEL");
}
}
}
private View.OnClickListener listener = new View.OnClickListener() {
@Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(activity);
integrator.initiateScan();
}
};
}
Latyout for Activity:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="@+id/capture"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Take a Picture"/>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tvContents"
android:layout_width="wrap_content"

</LinearLayout>
You might have output (maybe error/debug output) that precedes your call to
header("Content-type: text/xml");
Therefore, the content being delivered to the browser is not "xml"... that's what the error message is trying to tell you (at least that was the case for me and I had the same error message as you've described).
This should work:
$ mkdir -p dir
or:
if [[ ! -e $dir ]]; then
mkdir $dir
elif [[ ! -d $dir ]]; then
echo "$dir already exists but is not a directory" 1>&2
fi
which will create the directory if it doesn't exist, but warn you if the name of the directory you're trying to create is already in use by something other than a directory.
This is probably the easiest way:
new Date(<your-date-object>.toDateString());
Example: To get the Current Date without time component:
new Date(new Date().toDateString());
gives: Thu Jul 11 2019 00:00:00 GMT-0400 (Eastern Daylight Time)
Note this works universally, because toDateString()
produces date string with your browser's localization (without the time component), and the new Date()
uses the same localization to parse that date string.
Actually even font-awesome
CSS has a similar strategy for setting their icon styles. If you want to get a quick hold of the icon
code, check the non-minified font-awesome.css
file and there they are....each font in its purity.
No, if a is true (in a or
test), b will not be tested, as the result of the test will always be true, whatever is the value of the b expression.
Make a simple test:
if (true || ((String) null).equals("foobar")) {
...
}
will not throw a NullPointerException
!
take a look at generic method to print all elements in an array
but in short, the Arrays.toString(arr) is just a easy way of printing the content of a primative array.
This code snippet can be used for displaying time in seconds,milliseconds and microseconds:
#include <sys/time.h>
struct timeval start, stop;
double secs = 0;
gettimeofday(&start, NULL);
// Do stuff here
gettimeofday(&stop, NULL);
secs = (double)(stop.tv_usec - start.tv_usec) / 1000000 + (double)(stop.tv_sec - start.tv_sec);
printf("time taken %f\n",secs);
I like this approach because it is simple and clean:
String getCompaniesIdAndName = " select "
+ " c.id as id, "
+ " c.name as name "
+ " from Company c ";
@Query(value = getCompaniesWithoutAccount)
Set<CompanyIdAndName> findAllIdAndName();
public static interface CompanyIdAndName extends DTO {
Integer getId();
String getName();
}
In order to have a "function within a function", if I understand what you're asking, you need PHP 5.3, where you can take advantage of the new Closure feature.
So you could have:
public function newTest() {
$bigTest = function() {
//Big Test Here
}
}
If you can live with limited parallel capablilities, the following solution will work:
private static <T> Stream<T> nonEmptyStream(
Stream<T> stream, Supplier<RuntimeException> e) {
Spliterator<T> it=stream.spliterator();
return StreamSupport.stream(new Spliterator<T>() {
boolean seen;
public boolean tryAdvance(Consumer<? super T> action) {
boolean r=it.tryAdvance(action);
if(!seen && !r) throw e.get();
seen=true;
return r;
}
public Spliterator<T> trySplit() { return null; }
public long estimateSize() { return it.estimateSize(); }
public int characteristics() { return it.characteristics(); }
}, false);
}
Here is some example code using it:
List<String> l=Arrays.asList("hello", "world");
nonEmptyStream(l.stream(), ()->new RuntimeException("No strings available"))
.forEach(System.out::println);
nonEmptyStream(l.stream().filter(s->s.startsWith("x")),
()->new RuntimeException("No strings available"))
.forEach(System.out::println);
The problem with (efficient) parallel execution is that supporting splitting of the Spliterator
requires a thread-safe way to notice whether either of the fragments has seen any value in a thread-safe manner. Then the last of the fragments executing tryAdvance
has to realize that it is the last one (and it also couldn’t advance) to throw the appropriate exception. So I didn’t add support for splitting here.
To do this, you can loop through one and append to the other:
<?php
$test1 = array(
'11' => '11',
'22' => '22',
'33' => '33',
'44' => '44'
);
$test2 = array(
'44' => '44',
'55' => '55',
'66' => '66',
'77' => '77'
);
function combineWithKeys($array1, $array2)
{
foreach($array1 as $key=>$value) $array2[$key] = $value;
asort($array2);
return $array2;
}
print_r(combineWithKeys($test1, $test2));
?>
UPDATE: KingCrunch came up with the best solution: print_r($array1+$array2);
Lets see some simple examples of both __getattr__
and __getattribute__
magic methods.
__getattr__
Python will call __getattr__
method whenever you request an attribute that hasn't already been defined. In the following example my class Count has no __getattr__
method. Now in main when I try to access both obj1.mymin
and obj1.mymax
attributes everything works fine. But when I try to access obj1.mycurrent
attribute -- Python gives me AttributeError: 'Count' object has no attribute 'mycurrent'
class Count():
def __init__(self,mymin,mymax):
self.mymin=mymin
self.mymax=mymax
obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.mycurrent) --> AttributeError: 'Count' object has no attribute 'mycurrent'
Now my class Count has __getattr__
method. Now when I try to access obj1.mycurrent
attribute -- python returns me whatever I have implemented in my __getattr__
method. In my example whenever I try to call an attribute which doesn't exist, python creates that attribute and set it to integer value 0.
class Count:
def __init__(self,mymin,mymax):
self.mymin=mymin
self.mymax=mymax
def __getattr__(self, item):
self.__dict__[item]=0
return 0
obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.mycurrent1)
__getattribute__
Now lets see the __getattribute__
method. If you have __getattribute__
method in your class, python invokes this method for every attribute regardless whether it exists or not. So why we need __getattribute__
method? One good reason is that you can prevent access to attributes and make them more secure as shown in the following example.
Whenever someone try to access my attributes that starts with substring 'cur' python raises AttributeError
exception. Otherwise it returns that attribute.
class Count:
def __init__(self,mymin,mymax):
self.mymin=mymin
self.mymax=mymax
self.current=None
def __getattribute__(self, item):
if item.startswith('cur'):
raise AttributeError
return object.__getattribute__(self,item)
# or you can use ---return super().__getattribute__(item)
obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.current)
Important: In order to avoid infinite recursion in __getattribute__
method, its implementation should always call the base class method with the same name to access any attributes it needs. For example: object.__getattribute__(self, name)
or super().__getattribute__(item)
and not self.__dict__[item]
If your class contain both getattr and getattribute magic methods then __getattribute__
is called first. But if __getattribute__
raises
AttributeError
exception then the exception will be ignored and __getattr__
method will be invoked. See the following example:
class Count(object):
def __init__(self,mymin,mymax):
self.mymin=mymin
self.mymax=mymax
self.current=None
def __getattr__(self, item):
self.__dict__[item]=0
return 0
def __getattribute__(self, item):
if item.startswith('cur'):
raise AttributeError
return object.__getattribute__(self,item)
# or you can use ---return super().__getattribute__(item)
# note this class subclass object
obj1 = Count(1,10)
print(obj1.mymin)
print(obj1.mymax)
print(obj1.current)
falsetru's solution is nice, but has a little bug:
Suppose original 'id' length was larger than 5 characters. When we then dump with the new 'id' (134 with only 3 characters) the length of the string being written from position 0 in file is shorter than the original length. Extra chars (such as '}') left in file from the original content.
I solved that by replacing the original file.
import json
import os
filename = 'data.json'
with open(filename, 'r') as f:
data = json.load(f)
data['id'] = 134 # <--- add `id` value.
os.remove(filename)
with open(filename, 'w') as f:
json.dump(data, f, indent=4)
You will have to access db through the ip of host machine, or if you want to access it via localhost:1521, then run webserver like -
docker run --net=host --name oracle-wls wls-image:latest
You can use xpath for for identifying that element.
This is a warning from distutils, and is a sign that you do not have setuptools installed. Installing it from http://pypi.python.org/pypi/setuptools will remove the warning.
It`s possible to use MySQL specific syntax sugar:
SELECT ... date_field + INTERVAL 1 DAY
Looks much more pretty instead of DATE_ADD function
open up console and navigate to bin folder and run
JBOSS_HOME/bin > stanalone.sh
Once it is up and running just copy past your war file in
standalone/deployments folder
Thats probably it for jboss 7.1
There is a difference between signed and unsigned APK files. Most likely you had an unsigned on there previously. You just need to delete the unsigned before you install the signed version. How this can be accomplished varies on the exact version, but in general, go on the emulator to settings-> application, long click your app, and delete/remove/uninstall it.
There are some other ways too. I have used the following script:
$File = "D:\Dev\somefilename.zip";
$ftp = "ftp://username:[email protected]/pub/incoming/somefilename.zip";
Write-Host -Object "ftp url: $ftp";
$webclient = New-Object -TypeName System.Net.WebClient;
$uri = New-Object -TypeName System.Uri -ArgumentList $ftp;
Write-Host -Object "Uploading $File...";
$webclient.UploadFile($uri, $File);
And you could run a script against the windows FTP command line utility using the following command
ftp -s:script.txt
(Check out this article)
The following question on SO also answers this: How to script FTP upload and download?
Not exactly the answer to the question, but I needed to scroll down as soon as an EditText got the focus. However the accepted answer would make the ET also lose focus right away (to the ScrollView I assume).
My workaround was the following:
emailEt.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
Toast.makeText(getActivity(), "got the focus", Toast.LENGTH_LONG).show();
scrollView.postDelayed(new Runnable() {
@Override
public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
}, 200);
}else {
Toast.makeText(getActivity(), "lost the focus", Toast.LENGTH_LONG).show();
}
}
});
