git rev-parse --show-toplevel
could be enough if executed within a git repo.
From git rev-parse
man page:
--show-toplevel
Show the absolute path of the top-level directory.
For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":
git rev-parse --git-dir
That would give the path of the .git
directory.
The OP mentions:
git rev-parse --show-prefix
which returns the local path under the git repo root. (empty if you are at the git repo root)
Note: for simply checking if one is in a git repo, I find the following command quite expressive:
git rev-parse --is-inside-work-tree
And yes, if you need to check if you are in a .git
git-dir folder:
git rev-parse --is-inside-git-dir

EventEmitter
is a public, documented type in the final Angular Core API. Whether or not it is based on Observable
is irrelevant; if its documented emit
and subscribe
methods suit what you need, then go ahead and use it.
As also stated in the docs:
Uses Rx.Observable but provides an adapter to make it work as specified here: https://github.com/jhusain/observable-spec
Once a reference implementation of the spec is available, switch to it.
So they wanted an Observable
like object that behaved in a certain way, they implemented it, and made it public. If it were merely an internal Angular abstraction that shouldn't be used, they wouldn't have made it public.
There are plenty of times when it's useful to have an emitter which sends events of a specific type. If that's your use case, go for it. If/when a reference implementation of the spec they link to is available, it should be a drop-in replacement, just as with any other polyfill.
Just be sure that the generator you pass to the subscribe()
function follows the linked spec. The returned object is guaranteed to have an unsubscribe
method which should be called to free any references to the generator (this is currently an RxJs Subscription
object but that is indeed an implementation detail which should not be depended on).
export class MyServiceEvent {
message: string;
eventId: number;
}
export class MyService {
public onChange: EventEmitter<MyServiceEvent> = new EventEmitter<MyServiceEvent>();
public doSomething(message: string) {
// do something, then...
this.onChange.emit({message: message, eventId: 42});
}
}
export class MyConsumer {
private _serviceSubscription;
constructor(private service: MyService) {
this._serviceSubscription = this.service.onChange.subscribe({
next: (event: MyServiceEvent) => {
console.log(`Received message #${event.eventId}: ${event.message}`);
}
})
}
public consume() {
// do some stuff, then later...
this.cleanup();
}
private cleanup() {
this._serviceSubscription.unsubscribe();
}
}
All of the strongly-worded doom and gloom predictions seem to stem from a single Stack Overflow comment from a single developer on a pre-release version of Angular 2.
I needed time only up to one day, 24h, this was my take:
const milliseconds = 5680000;_x000D_
_x000D_
const hours = `0${new Date(milliseconds).getHours() - 1}`.slice(-2);_x000D_
const minutes = `0${new Date(milliseconds).getMinutes()}`.slice(-2);_x000D_
const seconds = `0${new Date(milliseconds).getSeconds()}`.slice(-2);_x000D_
_x000D_
const time = `${hours}:${minutes}:${seconds}`_x000D_
console.log(time);
_x000D_
you could get days this way as well if needed.
As explained in "Deleting your master branch" by Matthew Brett, you need to change your GitHub repo default branch.
You need to go to the GitHub page for your forked repository, and click on the “Settings” button.
Click on the "Branches" tab on the left hand side. There’s a “Default branch” dropdown list near the top of the screen.
From there, select placeholder (where placeholder is the dummy name for your new default branch).
Confirm that you want to change your default branch.
Now you can do (from the command line):
git push origin :master
Or, since 2012, you can delete that same branch directly on GitHub:
That was announced in Sept. 2013, a year after I initially wrote that answer.
For small changes like documentation fixes, typos, or if you’re just a walking software compiler, you can get a lot done in your browser without needing to clone the entire repository to your computer.
Note: for BitBucket, Tum reports in the comments:
About the same for Bitbucket
Repo -> Settings -> Repository details -> Main branch
Copy all file and replace to /var/lib/mysql ,
after that you must change owner of files to mysql
this is so important if mariadb.service restart has been faild
chown -R mysql:mysql /var/lib/mysql/*
and
chmod -R 700 /var/lib/mysql/*
Check the username credential used to login to the database. (persistence.xml ??). The problem mostly is, the username\password used to login to the database, does not have visiblity to the object (table_name in this case). ( try logging in to sql developer, using the same username\password available in your data source)
As other answers have stated, the ->
symbol is used as part of function annotations. In more recent versions of Python >= 3.5
, though, it has a defined meaning.
PEP 3107 -- Function Annotations described the specification, defining the grammar changes, the existence of func.__annotations__
in which they are stored and, the fact that it's use case is still open.
In Python 3.5
though, PEP 484 -- Type Hints attaches a single meaning to this: ->
is used to indicate the type that the function returns. It also seems like this will be enforced in future versions as described in What about existing uses of annotations:
The fastest conceivable scheme would introduce silent deprecation of non-type-hint annotations in 3.6, full deprecation in 3.7, and declare type hints as the only allowed use of annotations in Python 3.8.
(Emphasis mine)
This hasn't been actually implemented as of 3.6
as far as I can tell so it might get bumped to future versions.
According to this, the example you've supplied:
def f(x) -> 123:
return x
will be forbidden in the future (and in current versions will be confusing), it would need to be changed to:
def f(x) -> int:
return x
for it to effectively describe that function f
returns an object of type int
.
The annotations are not used in any way by Python itself, it pretty much populates and ignores them. It's up to 3rd party libraries to work with them.

See A comparison of the C++ casting operators.
However, using the same syntax for a variety of different casting operations can make the intent of the programmer unclear.
Furthermore, it can be difficult to find a specific type of cast in a large codebase.
the generality of the C-style cast can be overkill for situations where all that is needed is a simple conversion. The ability to select between several different casting operators of differing degrees of power can prevent programmers from inadvertently casting to an incorrect type.
I ran into a similar issue when trying to get composer to install some dependencies. It turns out the .dll my version of Wamp came with had a conflict, I am guessing, with 64 bit Windows.
This url has fixed curl dlls: http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/
Scroll down to the section that says: Fixed Curl Extensions.
I downloaded "php_curl-5.4.3-VC9-x64.zip". I just overwrote the dll inside the wamp/bin/php/php5.4.3/ext directory with the dll that was in the zip file and composer worked again.
I am running 64 bit Windows 8.
Hope this helps.
Okay, redis is pretty user friendly but there are some gotchas.
Here are just some easy commands for working with redis on Ubuntu:
install:
sudo apt-get install redis-server
start with conf:
sudo redis-server <path to conf>
sudo redis-server config/redis.conf
stop with conf:
redis-ctl shutdown
(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)
log:
tail -f /var/log/redis/redis-server.log
Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:
/etc/redis/redis.conf
Then paste it at <path to conf>
, tweak as needed and you're good to go.
The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.
If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.
Conceptually, the simplest regular expressions are literal characters. The pattern N
matches the character 'N'.
Regular expressions next to each other match sequences. For example, the pattern Nick
matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.
If you've ever used grep
on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re
in grep
refers to regular expressions.)
Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick
. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c]
matches either 'a' or 'b' or 'c'.
The pattern .
is special: rather than matching a literal dot only, it matches any character†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...]
.
Think of character classes as menus: pick just one.
Using .
can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]
. Digits are a frequent match target, so you could instead use the shortcut \d
. Others are \s
(whitespace) and \w
(word characters: alphanumerics or underscore).
The uppercased variants are their complements, so \S
matches any non-whitespace character, for example.
From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c
matches 'abc' or 'ac' because the ?
quantifier makes the subpattern it modifies optional. Other quantifiers are
*
(zero or more times)+
(one or more times){n}
(exactly n times){n,}
(at least n times){n,m}
(at least n times but no more than m times)Putting some of these blocks together, the pattern [Nn]*ick
matches all of
The first match demonstrates an important lesson: *
always succeeds! Any pattern can match zero times.
A few other useful examples:
[0-9]+
(and its equivalent \d+
) matches any non-negative integer\d{4}-\d{2}-\d{2}
matches dates formatted like 2019-01-01A quantifier modifies the pattern to its immediate left. You might expect 0abc+0
to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c
. This means 0abc+0
matches '0abc0', '0abcc0', '0abccc0', and so on.
To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0
. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr
.
Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick
. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |
, e.g., (Nick|nick)
.
For another example, you could equivalently write [a-c]
as a|b|c
, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.
Although some characters match themselves, others have special meanings. The pattern \d+
doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+
. A backslash removes the special meaning from the following character.
Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.
For example, say the input is
"Hello," she said, "How are you?"
You might expect ".+"
to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.
To switch from greedy to what you might think of as cautious, add an extra ?
to the quantifier. Now you understand how \((.+?)\)
, the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.
If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.
(As to your confusion, I don't know of any regular-expression dialect where ((.+?))
would do the same thing. I suspect something got lost in transmission somewhere along the way.)
Use the special pattern ^
to match only at the beginning of your input and $
to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.
Say you want to match comments of the form
-- This is a comment --
you'd write ^--\s+(.+)\s+--$
.
Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.
†: The statement above that .
matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n"
, but in practice you rarely expect a pattern such as .+
to cross a newline boundary. Perl regexes have a /s
switch and Java Pattern.DOTALL
, for example, to make .
match any character at all. For languages that don't have such a feature, you can use something like [\s\S]
to match "any whitespace or any non-whitespace", in other words anything.
The Flying Saucer XHTML renderer project has support for outputting XHTML to PDF. Have a look at an example here.
I think the simplest way would be to use a function with a foreach loop:
//This functions deletes the elements of an array $original that are equivalent to the value $del_val
//The function works by reference, which means that the actual array used as parameter will be modified.
function delete_value(&$original, $del_val)
{
//make a copy of the original, to avoid problems of modifying an array that is being currently iterated through
$copy = $original;
foreach ($original as $key => $value)
{
//for each value evaluate if it is equivalent to the one to be deleted, and if it is capture its key name.
if($del_val === $value) $del_key[] = $key;
};
//If there was a value found, delete all its instances
if($del_key !== null)
{
foreach ($del_key as $dk_i)
{
unset($original[$dk_i]);
};
//optional reordering of the keys. WARNING: only use it with arrays with numeric indexes!
/*
$copy = $original;
$original = array();
foreach ($copy as $value) {
$original[] = $value;
};
*/
//the value was found and deleted
return true;
};
//The value was not found, nothing was deleted
return false;
};
$original = array(0,1,2,3,4,5,6,7,4);
$del_val = 4;
var_dump($original);
delete_value($original, $del_val);
var_dump($original);
Output will be:

int(3)
[4]=>
int(4)

}

When script execution is halted (e.g., on a breakpoint) you can simply view all globals in the right pane of the Developer Tools window:
Unless you have a good reason, in your root controller do this:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(onTheEvent:)
name:@"ABCMyEvent"
object:nil];
And when you want to notify it:
[[NSNotificationCenter defaultCenter] postNotificationName:@"ABCMyEvent"
object:self];
I've mostly just seen the builtin ValueError

Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount()
in a React class.
For you edit, you may want to try something like this:
class Component extends React.Component {
constructor(props) {
super(props);
this.onAddBucket = this.onAddBucket.bind(this);
}
componentWillMount() {
this.setState({
buckets: {},
})
}
componentDidMount() {
this.onAddBucket();
}
onAddBucket() {
let self = this;
let getToken = localStorage.getItem('myToken');
var apiBaseUrl = "...";
let input = {
"name" : this.state.fields["bucket_name"]
}
axios.defaults.headers.common['Authorization'] = getToken;
axios.post(apiBaseUrl+'...',input)
.then(function (response) {
if (response.data.status == 200) {
this.setState({
buckets: this.state.buckets.concat(response.data.buckets),
});
} else {
alert(response.data.message);
}
})
.catch(function (error) {
console.log(error);
});
}
render() {
return (
{this.state.bucket}
);
}
}

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;
That method was added in Servlet 2.5.
So this problem can have at least 3 causes:
web.xml
is not declared conform Servlet 2.5 or newer.To solve it,
web.xml
complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.servlet-api.jar
or j2ee.jar
in /WEB-INF/lib
or even worse, the JRE/lib
or JRE/lib/ext
. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.Java doesn't support default parameters. You will need to have two constructors to do what you want.
An alternative if there are lots of possible values with defaults is to use the Builder pattern, whereby you use a helper object with setters.
e.g.
public class Foo {
private final String param1;
private final String param2;
private Foo(Builder builder) {
this.param1 = builder.param1;
this.param2 = builder.param2;
}
public static class Builder {
private String param1 = "defaultForParam1";
private String param2 = "defaultForParam2";
public Builder param1(String param1) {
this.param1 = param1;
return this;
}
public Builder param2(String param1) {
this.param2 = param2;
return this;
}
public Foo build() {
return new Foo(this);
}
}
}
which allows you to say:
Foo myFoo = new Foo.Builder().param1("myvalue").build();
which will have a default value for param2
.
Try passing width=200
as additional paramater when creating the Label.
This should work in creating label with specified width.
If you want to change it later, you can use:
label.config(width=200)
As you want to change the size of font itself you can try:
label.config(font=("Courier", 44))

Maven versions can contain a string literal "SNAPSHOT" to signify that a project is currently under active development.
For example, if your project has a version of “1.0-SNAPSHOT” and you deploy this project’s artifacts to a Maven repository, Maven would expand this version to “1.0-20080207-230803-1” if you were to deploy a release at 11:08 PM on February 7th, 2008 UTC. In other words, when you deploy a snapshot, you are not making a release of a software component; you are releasing a snapshot of a component at a specific time.
So mainly snapshot versions are used for projects under active development. If your project depends on a software component that is under active development, you can depend on a snapshot release, and Maven will periodically attempt to download the latest snapshot from a repository when you run a build. Similarly, if the next release of your system is going to have a version “1.8,” your project would have a “1.8-SNAPSHOT” version until it was formally released.
For example , the following dependency would always download the latest 1.8 development JAR of spring:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>1.8-SNAPSHOT”</version>
</dependency>
An example of maven release process
This is not a direct answer to the question. Rather it answers this question: "How do I choose a specific function output from many possible options?".
If you are able to write the function (ie, it is not in a library you cannot modify), then add an input argument that indicates what you want out of the function. Make it a named argument with a default value so in the "common case" you don't even have to specify it.
def fancy_function( arg1, arg2, return_type=1 ):
ret_val = None
if( 1 == return_type ):
ret_val = arg1 + arg2
elif( 2 == return_type ):
ret_val = [ arg1, arg2, arg1 * arg2 ]
else:
ret_val = ( arg1, arg2, arg1 + arg2, arg1 * arg2 )
return( ret_val )
This method gives the function "advanced warning" regarding the desired output. Consequently it can skip unneeded processing and only do the work necessary to get your desired output. Also because Python does dynamic typing, the return type can change. Notice how the example returns a scalar, a list or a tuple... whatever you like!
You have to add repositories
to your build file. For maven repositories you have to prefix repository name with maven{}
repositories {
maven { url "http://maven.springframework.org/release" }
maven { url "http://maven.restlet.org" }
mavenCentral()
}
Basically it checks if the value before the || evaluates to true, if yes, it takes this value, if not, it takes the value after the ||.
Values for which it will take the value after the || (as far as i remember):
For curious minds and to complete the conversation: Yes, String is a reference type:
unsafe
{
string a = "Test";
string b = a;
fixed (char* p = a)
{
p[0] = 'B';
}
Console.WriteLine(a); // output: "Best"
Console.WriteLine(b); // output: "Best"
}
But note that this change only works in an unsafe block! because Strings are immutable (From MSDN):
The contents of a string object cannot be changed after the object is created, although the syntax makes it appear as if you can do this. For example, when you write this code, the compiler actually creates a new string object to hold the new sequence of characters, and that new object is assigned to b. The string "h" is then eligible for garbage collection.
string b = "h";
b += "ello";
And keep in mind that:
Although the string is a reference type, the equality operators (
==
and!=
) are defined to compare the values of string objects, not references.
Your command line should have a -d/--data inserted before the string you want to send in the PUT, and you want to set the Content-Type and not Accept.
curl -H 'Content-Type: application/json' -X PUT -d '[JSON]' \
http://example.com/service
Using the exact JSON data from the question, the full command line would become:
curl -H 'Content-Type: application/json' -X PUT \
-d '{"tags":["tag1","tag2"],
"question":"Which band?",
"answers":[{"id":"a0","answer":"Answer1"},
{"id":"a1","answer":"answer2"}]}' \
http://example.com/service
Note: JSON data wrapped only for readability, not valid for curl
request.

Tested on API 21
EDIT: You cannot overload operators in current, common browser-based implementations of JavaScript interpreters.
To answer the original question, one way you could do this, and mind you, this is a bit of a hack, simply serialize the two arrays to JSON and then compare the two JSON strings. That would simply tell you if the arrays are different, obviously you could do this to each of the objects within the arrays as well to see which ones were different.
Another option is to use a library which has some nice facilities for comparing objects - I use and recommend MochiKit.
EDIT: The answer kamens gave deserves consideration as well, since a single function to compare two given objects would be much smaller than any library to do what I suggest (although my suggestion would certainly work well enough).
Here is a naïve implemenation that may do just enough for you - be aware that there are potential problems with this implementation:
function objectsAreSame(x, y) {
var objectsAreSame = true;
for(var propertyName in x) {
if(x[propertyName] !== y[propertyName]) {
objectsAreSame = false;
break;
}
}
return objectsAreSame;
}
The assumption is that both objects have the same exact list of properties.
Oh, and it is probably obvious that, for better or worse, I belong to the only-one-return-point camp. :)
After messing around with @BringBackCommodore64 answer I figured it out
[link](file:///d:/absolute.md) # absolute filesystem path
[link](./relative1.md) # relative to opened file
[link](/relativeToProject.md) # relative to opened project
All of them tested in Visual Studio Code
and working,
Note: The absolute path works in editor but doesn't work in markdown preview mode!
Many people have already mentioned that document.cookie
gets you all the cookies (except http-only
ones).
I'll just add a snippet to keep up with the times.
document.cookie.split(';').reduce((cookies, cookie) => {
const [ name, value ] = cookie.split('=').map(c => c.trim());
cookies[name] = value;
return cookies;
}, {});
The snippet will return an object with cookie names as the keys with cookie values as the values.
Slightly different syntax:
document.cookie.split(';').reduce((cookies, cookie) => {
const [ name, value ] = cookie.split('=').map(c => c.trim());
return { ...cookies, [name]: value };
}, {});
I think you should use python wheels for distribution instead of egg now.
Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.
Two ways come to mind:
Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that
Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.
According to Oracle's Java Documentation:
private static final Pattern NUMBER_PATTERN = Pattern.compile(
"[\\x00-\\x20]*[+-]?(NaN|Infinity|((((\\p{Digit}+)(\\.)?((\\p{Digit}+)?)" +
"([eE][+-]?(\\p{Digit}+))?)|(\\.((\\p{Digit}+))([eE][+-]?(\\p{Digit}+))?)|" +
"(((0[xX](\\p{XDigit}+)(\\.)?)|(0[xX](\\p{XDigit}+)?(\\.)(\\p{XDigit}+)))" +
"[pP][+-]?(\\p{Digit}+)))[fFdD]?))[\\x00-\\x20]*");
boolean isNumber(String s){
return NUMBER_PATTERN.matcher(s).matches()
}
I can't give you graphics, but maybe I can give a clear explanation.
Suppose we have an information channel, such as a light that flashes once every day either red or green. How much information does it convey? The first guess might be one bit per day. But what if we add blue, so that the sender has three options? We would like to have a measure of information that can handle things other than powers of two, but still be additive (the way that multiplying the number of possible messages by two adds one bit). We could do this by taking log2(number of possible messages), but it turns out there's a more general way.
Suppose we're back to red/green, but the red bulb has burned out (this is common knowledge) so that the lamp must always flash green. The channel is now useless, we know what the next flash will be so the flashes convey no information, no news. Now we repair the bulb but impose a rule that the red bulb may not flash twice in a row. When the lamp flashes red, we know what the next flash will be. If you try to send a bit stream by this channel, you'll find that you must encode it with more flashes than you have bits (50% more, in fact). And if you want to describe a sequence of flashes, you can do so with fewer bits. The same applies if each flash is independent (context-free), but green flashes are more common than red: the more skewed the probability the fewer bits you need to describe the sequence, and the less information it contains, all the way to the all-green, bulb-burnt-out limit.
It turns out there's a way to measure the amount of information in a signal, based on the the probabilities of the different symbols. If the probability of receiving symbol xi is pi, then consider the quantity
-log pi
The smaller pi, the larger this value. If xi becomes twice as unlikely, this value increases by a fixed amount (log(2)). This should remind you of adding one bit to a message.
If we don't know what the symbol will be (but we know the probabilities) then we can calculate the average of this value, how much we will get, by summing over the different possibilities:
I = -Σ pi log(pi)
This is the information content in one flash.
Red bulb burnt out: pred = 0, pgreen=1, I = -(0 + 0) = 0 Red and green equiprobable: pred = 1/2, pgreen = 1/2, I = -(2 * 1/2 * log(1/2)) = log(2) Three colors, equiprobable: pi=1/3, I = -(3 * 1/3 * log(1/3)) = log(3) Green and red, green twice as likely: pred=1/3, pgreen=2/3, I = -(1/3 log(1/3) + 2/3 log(2/3)) = log(3) - 2/3 log(2)
This is the information content, or entropy, of the message. It is maximal when the different symbols are equiprobable. If you're a physicist you use the natural log, if you're a computer scientist you use log2 and get bits.
Another version with Promise's modern method. It's shorter that the others responses based on Promise :
const readFiles = (dirname) => {
const readDirPr = new Promise( (resolve, reject) => {
fs.readdir(dirname,
(err, filenames) => (err) ? reject(err) : resolve(filenames))
});
return readDirPr.then( filenames => Promise.all(filenames.map((filename) => {
return new Promise ( (resolve, reject) => {
fs.readFile(dirname + filename, 'utf-8',
(err, content) => (err) ? reject(err) : resolve(content));
})
})).catch( error => Promise.reject(error)))
};
readFiles(sourceFolder)
.then( allContents => {
// handle success treatment
}, error => console.log(error));
Shortest example of code:
<p><span>Some text</span></p>
p {
position: relative;
pointer-events: none;
}
p::before {
content: "";
position: absolute;
pointer-events: auto;
}
p span {
display: contents;
pointer-events: auto;
}
const all_p = Array.from(document.querySelectorAll('p'));
for (let p of all_p) {
p.addEventListener("click", listener, false);
};
pointer-events
control detection of events, removing receiving events from target, but keep receiving from pseudo-elements make possible to click on ::before
and ::after
and you will always know what you are clicking on pseudo-element, however if you still need to click, you put all content in nested element (span
in example), but because we don't want to apply any additional styles, display: contents;
become very handy solution and it supported by most browsers. pointer-events: none;
as already mentioned in original post also widely supported.
The JavaScript part also used widely supported Array.from
and for...of
, however they are not necessary to use in code.
You can apply a centering to any View, including a Layout, by using the XML attribute android:layout_gravity". You probably want to give it the value "center".
You can find a reference of possible values for this option here: http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html#attr_android:layout_gravity
Pure Bash, no external utilities
This demonstration does full justification, but you can just omit subtracting the length of the second string if you want ragged-right lines.
pad=$(printf '%0.1s' "-"{1..60})
padlength=40
string2='bbbbbbb'
for string1 in a aa aaaa aaaaaaaa
do
printf '%s' "$string1"
printf '%*.*s' 0 $((padlength - ${#string1} - ${#string2} )) "$pad"
printf '%s\n' "$string2"
string2=${string2:1}
done
Unfortunately, in that technique, the length of the pad string has to be hardcoded to be longer than the longest one you think you'll need, but the padlength can be a variable as shown. However, you can replace the first line with these three to be able to use a variable for the length of the pad:
padlimit=60
pad=$(printf '%*s' "$padlimit")
pad=${pad// /-}
So the pad (padlimit
and padlength
) could be based on terminal width ($COLUMNS
) or computed from the length of the longest data string.
Output:
a--------------------------------bbbbbbb
aa--------------------------------bbbbbb
aaaa-------------------------------bbbbb
aaaaaaaa----------------------------bbbb
Without subtracting the length of the second string:
a---------------------------------------bbbbbbb
aa--------------------------------------bbbbbb
aaaa------------------------------------bbbbb
aaaaaaaa--------------------------------bbbb
The first line could instead be the equivalent (similar to sprintf
):
printf -v pad '%0.1s' "-"{1..60}
or similarly for the more dynamic technique:
printf -v pad '%*s' "$padlimit"
You can do the printing all on one line if you prefer:
printf '%s%*.*s%s\n' "$string1" 0 $((padlength - ${#string1} - ${#string2} )) "$pad" "$string2"
If you're using a Mac computer, you can use the new updateR package to update the R version from RStudio: http://www.andreacirillo.com/2018/02/10/updater-package-update-r-version-with-a-function-on-mac-osx/
In summary, you need to perform this:
To update your R version from within Rstudio using updateR you just have to run these five lines of code:
install.packages('devtools') #assuming it is not already installed library(devtools) install_github('andreacirilloac/updateR') library(updateR) updateR(admin_password = 'Admin user password')
at the end of installation process a message is going to confirm you the happy end:
everything went smoothly open a Terminal session and run 'R' to assert that latest version was installed
Actually, I have got this error a while ago. There are two ways to make this to work, as per my knowledge.
solve using this code:
npm install npm@latest -g
git show
is more a plumbing command than git log
, and has the same formatting options:
git show -s --format=%B SHA1
To resolve problem go to the MDaemon-->setup-->Miscellaneous options-->Server-->SMTP Server Checks commands and headers for RFC Compliance
Use os.path.normpath
, then os.path.basename
:
>>> os.path.basename(os.path.normpath('/folderA/folderB/folderC/folderD/'))
'folderD'
The first strips off any trailing slashes, the second gives you the last part of the path. Using only basename
gives everything after the last slash, which in this case is ''
.
In addition, gcc will look in the directories specified after the -I
option.
Like this:
border: 1px solid black;
Why it didn't work? because:
Always declare the border-style (solid in my example) property before the border-width property. An element must have borders before you can change the color.
Use non-static position along with greater z-index in child element:
.parent {
position: absolute
z-index: 100;
}
.child {
position: relative;
z-index: 101;
}
From Netbeans 8.1 - there is an "Import from ZIP" option.
Go to Main Menu -> File -> Import Project -> from ZIP.
Browse your .ZIP file's location via Browse button.
If you have Java project depending on external Libraries, Netbeans will highlight & ask for "Resolving problems" in project, click on resolve, provide location in your file system containing required library files .e.g JARs etc & you will be good to go.
You can user UIBezierPath Class for this:
And can draw as many lines as you want:
I have subclassed UIView :
@interface MyLineDrawingView()
{
NSMutableArray *pathArray;
NSMutableDictionary *dict_path;
CGPoint startPoint, endPoint;
}
@property (nonatomic,retain) UIBezierPath *myPath;
@end
And initialized the pathArray and dictPAth objects which will be used for line drawing. I am writing the main portion of the code from my own project:
- (void)drawRect:(CGRect)rect
{
for(NSDictionary *_pathDict in pathArray)
{
[((UIColor *)[_pathDict valueForKey:@"color"]) setStroke]; // this method will choose the color from the receiver color object (in this case this object is :strokeColor)
[[_pathDict valueForKey:@"path"] strokeWithBlendMode:kCGBlendModeNormal alpha:1.0];
}
[[dict_path objectForKey:@"color"] setStroke]; // this method will choose the color from the receiver color object (in this case this object is :strokeColor)
[[dict_path objectForKey:@"path"] strokeWithBlendMode:kCGBlendModeNormal alpha:1.0];
}
touchesBegin method :
UITouch *touch = [touches anyObject];
startPoint = [touch locationInView:self];
myPath=[[UIBezierPath alloc]init];
myPath.lineWidth = currentSliderValue*2;
dict_path = [[NSMutableDictionary alloc] init];
touchesMoved Method:
UITouch *touch = [touches anyObject];
endPoint = [touch locationInView:self];
[myPath removeAllPoints];
[dict_path removeAllObjects];// remove prev object in dict (this dict is used for current drawing, All past drawings are managed by pathArry)
// actual drawing
[myPath moveToPoint:startPoint];
[myPath addLineToPoint:endPoint];
[dict_path setValue:myPath forKey:@"path"];
[dict_path setValue:strokeColor forKey:@"color"];
// NSDictionary *tempDict = [NSDictionary dictionaryWithDictionary:dict_path];
// [pathArray addObject:tempDict];
// [dict_path removeAllObjects];
[self setNeedsDisplay];
touchesEnded Method:
NSDictionary *tempDict = [NSDictionary dictionaryWithDictionary:dict_path];
[pathArray addObject:tempDict];
[dict_path removeAllObjects];
[self setNeedsDisplay];
Check out emailjs
After wasting lots of time on trying to make nodemailer work with large attachments, found emailjs and happy ever since.
It supports sending files by using normal File objects, and not huge Buffers as nodemailer requires. Means that you can link it to, f.e., formidable to pass the attachments from an html form to the mailer. It also supports queueing..
All in all, no idea why nodejitsu ppl chose nodemailer to base their version on, emailjs is just much more advanced.
Use Object#toString()
.
String string = map.toString();
That's after all also what System.out.println(object)
does under the hoods. The format for maps is described in AbstractMap#toString()
.
Returns a string representation of this map. The string representation consists of a list of key-value mappings in the order returned by the map's
entrySet
view's iterator, enclosed in braces ("{}"). Adjacent mappings are separated by the characters ", " (comma and space). Each key-value mapping is rendered as the key followed by an equals sign ("=") followed by the associated value. Keys and values are converted to strings as byString.valueOf(Object)
.
I usually use either komodo edit or aquamacs with ropemacs. Although I should warn you, IDE features won't be what you're used to if you're coming from a Java or C# background. I personally find that powerful IDEs get in my way more than they help.
UPDATE: I should also point out that if you have the money Komodo IDE is worth it. It's the paid version of Komodo Edit.
you can use online library
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
or else download library and add css in css folder and jquery in js folder.both folder you keep in laravel public folder then you can link like below
<link rel="stylesheet" href="{{asset('css/bootstrap-theme.min.css')}}">
<script src="{{asset('js/jquery.min.js')}}"></script>
or else
{{ HTML::style('css/style.css') }}
{{ HTML::script('js/functions.js') }}
Here's the config for ISAPI_Rewrite 3:
RewriteBase /
RewriteCond %{HTTP_HOST} ^mysite.org.uk$ [NC]
RewriteRule ^stuff/(.+)$ http://stuff.mysite.org.uk/$1 [NC,R=301,L]
You can reset the root password by running the server with --skip-grant-tables
and logging in without a password by running the following as root (or with sudo):
# service mysql stop
# mysqld_safe --skip-grant-tables &
$ mysql -u root
mysql> use mysql;
mysql> update user set authentication_string=PASSWORD("YOUR-NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
mysql> quit
# service mysql stop
# service mysql start
$ mysql -u root -p
Now you should be able to login as root with your new password.
It is also possible to find the query that reset the password in /home/$USER/.mysql_history
or /root/.mysql_history
of the user who reset the password, but the above will always work.
Note: prior to MySQL 5.7 the column was called password
instead of authentication_string
. Replace the line above with
mysql> update user set password=PASSWORD("YOUR-NEW-ROOT-PASSWORD") where User='root';
In regards to @RitchieD response, here is a jQuery plugin version to make things easier if you are using jQuery.
(function ($) {
$.fn.initValidation = function () {
$(this).removeData("validator");
$(this).removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse(this);
return this;
};
}(jQuery));
This can be used like this:
$("#SomeForm").initValidation();
Use a FrameLayout with two children. The two children will be overlapped. This is recommended in one of the tutorials from Android actually, it's not a hack...
Here is an example where a TextView is displayed on top of an ImageView:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="center"
android:src="@drawable/golden_gate" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dip"
android:layout_gravity="center_horizontal|bottom"
android:padding="12dip"
android:background="#AA000000"
android:textColor="#ffffffff"
android:text="Golden Gate" />
</FrameLayout>
If use this on capitalized text;
p text-transform: lowercase;
Then show the text, it is lowercase but if you copy that lower-cased text, and paste it, it change back to original capitalized.
I've used a technique similar to McVitie's, and only in stored procedures or scripts that are pretty long. I will break down certain functional portions like this:
BEGIN /** delete queries **/
DELETE FROM blah_blah
END /** delete queries **/
BEGIN /** update queries **/
UPDATE sometable SET something = 1
END /** update queries **/
This method shows up fairly nice in management studio and is really helpful in reviewing code. The collapsed piece looks sort of like:
BEGIN /** delete queries **/ ... /** delete queries **/
I actually prefer it this way because I know that my BEGIN
matches with the END
this way.
instead of onmouseout use onmouseleave.
You haven't showed to us your specific code so I cannot show you on your specific example how to do it.
But it is very simple: just replace onmouseout with onmouseleave.
That's all :) So, simple :)
If not sure how to do it, see explanation on:
https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_onmousemove_leave_out
Peace of cake :) Enjoy it :)
Qberticus's answer is good, but one useful detail is missing. If you are implementing these in a library replace:
xmlns:whatever="http://schemas.android.com/apk/res/org.example.mypackage"
with:
xmlns:whatever="http://schemas.android.com/apk/res-auto"
Otherwise the application that uses the library will have runtime errors.
What you can do is use WMI to get the paths. This will allow you to get the path regardless it's a 32-bit or 64-bit application. Here's an example demonstrating how you can get it:
// include the namespace
using System.Management;
var wmiQueryString = "SELECT ProcessId, ExecutablePath, CommandLine FROM Win32_Process";
using (var searcher = new ManagementObjectSearcher(wmiQueryString))
using (var results = searcher.Get())
{
var query = from p in Process.GetProcesses()
join mo in results.Cast<ManagementObject>()
on p.Id equals (int)(uint)mo["ProcessId"]
select new
{
Process = p,
Path = (string)mo["ExecutablePath"],
CommandLine = (string)mo["CommandLine"],
};
foreach (var item in query)
{
// Do what you want with the Process, Path, and CommandLine
}
}
Note that you'll have to reference the System.Management.dll
assembly and use the System.Management
namespace.
For more info on what other information you can grab out of these processes such as the command line used to start the program (CommandLine
), see the Win32_Process class and WMI .NET for for more information.
Adapted from this post on Processing JSON with jq, you can use the select(bool)
like this:
$ jq '.[] | select(.location=="Stockholm")' json
{
"location": "Stockholm",
"name": "Walt"
}
{
"location": "Stockholm",
"name": "Donald"
}
I made good experiences with Scala.
I use the simple build tool (sbt: http://code.google.com/p/simple-build-tool/) with the Android-Plugin (http://github.com/jberkel/android-plugin)
try this command line below for MacOS to check user's permission.
$ sudo python -m pip install --user --upgrade pip
Save your sorting order in a ViewState.
private const string ASCENDING = " ASC";
private const string DESCENDING = " DESC";
public SortDirection GridViewSortDirection
{
get
{
if (ViewState["sortDirection"] == null)
ViewState["sortDirection"] = SortDirection.Ascending;
return (SortDirection) ViewState["sortDirection"];
}
set { ViewState["sortDirection"] = value; }
}
protected void GridView_Sorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
if (GridViewSortDirection == SortDirection.Ascending)
{
GridViewSortDirection = SortDirection.Descending;
SortGridView(sortExpression, DESCENDING);
}
else
{
GridViewSortDirection = SortDirection.Ascending;
SortGridView(sortExpression, ASCENDING);
}
}
private void SortGridView(string sortExpression,string direction)
{
// You can cache the DataTable for improving performance
DataTable dt = GetData().Tables[0];
DataView dv = new DataView(dt);
dv.Sort = sortExpression + direction;
GridView1.DataSource = dv;
GridView1.DataBind();
}
Why you don't want to use existing sorting functionality? You can always customize it.
Sorting Data in a GridView Web Server Control at MSDN
Here is an example with customization:
When using the .html()
method, a htmlString
must be the parameter. (source) Put your string inside a HTML tag and it should work or use .text()
as suggested by farzad.
Example:
<div class="demo-container">
<div class="demo-box">Demonstration Box</div>
</div>
<script type="text/javascript">
$("div.demo-container").html( "<p>All new content. <em>You bet!</em></p>" );
</script>
Try this
SELECT * FROM
(
SELECT T.*, ROW_NUMBER() OVER() R FROM TABLE T
)
WHERE R BETWEEN 10000 AND 20000
Using .one
ensures this is done only once and not repeatedly.
$(window).one("focus", function() {
localStorage.clear();
});
It is okay to put several document.ready event listeners (if you need other events to execute multiple times) as long as you do not overdo it, for the sake of readability.
.one
is especially useful when you want local storage to be cleared only once the first time a web page is opened or when a mobile application is installed the first time.
// Fired once when document is ready
$(document).one('ready', function () {
localStorage.clear();
});
This worked for me:
min-height: 14px;
height: 14px;
Looks like you forgot the mode parameter when calling open
, try w
:
file = open("copy.txt", "w")
file.write("Your text goes here")
file.close()
The default value is r
and will fail if the file does not exist
'r' open for reading (default)
'w' open for writing, truncating the file first
Other interesting options are
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
See Doc for Python2.7 or Python3.6
-- EDIT --
As stated by chepner in the comment below, it is better practice to do it with a with
statement (it guarantees that the file will be closed)
with open("copy.txt", "w") as file:
file.write("Your text goes here")
Your question is a bit unclear, but I think you want (requires using System.Linq;
):
var result = yourArrayOfStrings.SelectMany(s => s).ToArray();
Another solution is:
var result = string.Concat(yourArrayOfStrings).ToCharArray();
Another way to compile C# programs (without using Visual Studio or without having it installed) is to create a user variable in environment variables, namely "PATH".
Copy the following path in this variable:
"C:\Windows\Microsoft.NET\Framework\v4.0.30319"
or depending upon which .NET your PC have.
So you don't have to mention the whole path every time you compile a code. Simply use
"C:\Users\UserName\Desktop>csc [options] filename.cs"
or wherever the path of your code is.
Now you are good to go.
in regard of answer from @Perception, its true to be very memory-consuming when working with byte arrays, but you could also simply write back into the outputstream
@Path("/picture")
public class ProfilePicture {
@GET
@Path("/thumbnail")
@Produces("image/png")
public StreamingOutput getThumbNail() {
return new StreamingOutput() {
@Override
public void write(OutputStream os) throws IOException, WebApplicationException {
//... read your stream and write into os
}
};
}
}
# this works:
rm foo
# versus this, which doesn't:
rm foo/
Basically, you need to tell it to delete a file, not delete a directory. I believe the difference between rm
and rmdir
exists because of differences in the way the C library treats each.
At any rate, the first should work, while the second should complain about foo being a directory.
If it doesn't work as above, then check your permissions. You need write permission to the containing directory to remove files.
for Chinese user, just add two lines below to you config/application.rb
:
config.active_record.default_timezone = :local
config.time_zone = 'Beijing'
You can use the following rule to redirect from https to http :
RewriteEngine On
RewriteCond %{HTTPS} ^on$
RewriteRule ^(.*)$ http://example.com/$1 [NC,L,R]
Explanation :
RewriteCond %{HTTPS} ^on$
Checks if the HTTPS is on (Request is made using https)
Then
RewriteRule ^(.*)$ http://example.com/$1 [NC,L,R]
Redirect any request (https://example.com/foo) to http://example.com/foo .
$1 is part of the regex in RewriteRule pattern, it contains whatever value was captured in (.+) , in this case ,it captures the full request_uri everything after the domain name.
[NC,L,R] are the flags, NC makes the uri case senstive, you can use both uppercase or lowercase letters in the request.
L flag tells the server to stop proccessing other rules if the currunt rule has matched, it is important to use the L flag to avoid rule confliction when you have more then on rules in a block.
R flag is used to make an external redirection.
The default session.save_path
is set to ""
which will evaluate to your system's temp directory. See this comment at https://bugs.php.net/bug.php?id=26757 stating:
The new default for save_path in upcoming releaess (sic) will be the empty string, which causes the temporary directory to be probed.
You can use sys_get_temp_dir
to return the directory path used for temporary files
To find the current session save path, you can use
Refer to this answer to find out what the temp path is when this function returns an empty string.
AllowOverride AuthConfig
try this. Authentication may be the problem. I was working with a CGI script written in C++, and faced some authentication issues when passed DELETE. The above solution helped me. It may help in your case too.
Also even if you don't get the solution for your problem of PUT and DELETE, do not stop working rather use "CORS". It is a google chrome app, which will help you bypass the problem, but remember it is a temporary solution, so that your work or experiments doesn't remain freeze for long. Obviously, you cannot ask your client to have "CORS" enabled to run your solution, as it may compromise systems security.
Usually this is an OpenSSL version mismatch error, between Apache and PHP. In case Apache loads PHP as a DSO module, its own OpenSSL versions (dlls and libs) will be used. So, in case the PHP extension requires a newer version, it may not find the appropriate interface inside the Apache-loaded DLLS and it will fail to work.
Since you need the PHP extension to load, you need the relevant DLL files to be at least the version of what the PHP module asks for. Supposing that you 're using lastest builds for both Apache and PHP and both having been built with the same MVC version, you can copy the following files:
from the PHP root folder to the Apache2/bin folder, in case you 're confident that the PHP build is newer than the Apache build.
In the opposite case, you can copy the same files from the Apache BIN to the PHP root.
In any case, backup the contents of the APache and PHP folders beforehand.
Adding the PHP path as an enviromental variable will give priority to this path for loading the relevant DLLs and may solve the problem. However, you lose in server portability. Additionally, if you have also added the Apache PATH as a variable and the OpenSSL versions are way different (up to loading different linked DLL files), a lot of shit may happen.
You could try this:
$(".edgetoedge").children().removeClass("highlight");
I have just used dompdf and the code was a little different but it worked.
Here it is:
require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);
$html =
'<html><body>'.
'<p>Put your html here, or generate it with your favourite '.
'templating system.</p>'.
'</body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$output = $dompdf->output();
file_put_contents('Brochure.pdf', $output);
Only difference here is that all of the files in the include directory are included.
Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.
select Main form -> properties -> Windows style -> icon -> browse your ico
this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
I most cases, creating a temporary file named after your variable name might be acceptable. (as you are probably using meaningful variables name...)
Here, my variable name is SSH_PAGEANT_AUTH_SOCK
dir /w "\\.\pipe\\"|find "pageant" > %temp%\SSH_PAGEANT_AUTH_SOCK && set /P SSH_PAGEANT_AUTH_SOCK=<%temp%\SSH_PAGEANT_AUTH_SOCK
Maybe, something like
for t in threading.enumerate():
if t.daemon:
t.join()
The CSS selector for the direct first-child in your case is:
.section > :first-child
The direct selector is > and the first child selector is :first-child
No need for an asterisk before the : as others suggest. You could speed up the DOM searching by modifying this solution by prepending the tag:
div.section > :first-child
You need to use Range
and Valu
e functions.
Range
would be the cell where you want the text you want
Value
would be the text that you want in that Cell
Range("A1").Value="whatever text"
We can use title()
function with negative line
value to bring down the title.
See this example:
plot(1, 1)
title("Title", line = -2)
1.Go to your manifest.xml
file.
2.Find

The best way in javascript to do so is
function getBinaryValue(num){
return num.toString(2);
}
function checkOnces(binaryValue){
return binaryValue.toString().replace(/0/g, "").length;
}
where binaryValue is the binary String eg: 1100
There's some proposition over the web (and this page) to use ViewConfiguration.getScaledTouchSlop() to have a device-scaled value for SWIPE_MIN_DISTANCE
.
getScaledTouchSlop()
is intended for the "scrolling threshold" distance, not swipe. The scrolling threshold distance has to be smaller than a "swing between page" threshold distance. For example, this function returns 12 pixels on my Samsung GS2, and the examples quoted in this page are around 100 pixels.
With API Level 8 (Android 2.2, Froyo), you've got getScaledPagingTouchSlop()
, intended for page swipe.
On my device, it returns 24 (pixels). So if you're on API Level < 8, I think "2 * getScaledTouchSlop()
" should be the "standard" swipe threshold.
But users of my application with small screens told me that it was too few... As on my application, you can scroll vertically, and change page horizontally. With the proposed value, they sometimes change page instead of scrolling.
Got the issue for months, and finally discovered that when we disable DNSSEC on our api domain, everything was ok :simple_smile:
try
{
// Some code
}
catch (Web2PDFException ex)
{
// It's your special exception
}
catch (Exception ex)
{
// Any other exception here
}
In Python 3, use
print('h', end='')
to suppress the endline terminator, and
print('a', 'b', 'c', sep='')
to suppress the whitespace separator between items. See the documentation for print
Give your radiobutton a custom style:
<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
<item name="android:button">@drawable/custom_btn_radio</item>
</style>
custom_btn_radio.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:state_window_focused="false"
android:drawable="@drawable/btn_radio_on" />
<item android:state_checked="false" android:state_window_focused="false"
android:drawable="@drawable/btn_radio_off" />
<item android:state_checked="true" android:state_pressed="true"
android:drawable="@drawable/btn_radio_on_pressed" />
<item android:state_checked="false" android:state_pressed="true"
android:drawable="@drawable/btn_radio_off_pressed" />
<item android:state_checked="true" android:state_focused="true"
android:drawable="@drawable/btn_radio_on_selected" />
<item android:state_checked="false" android:state_focused="true"
android:drawable="@drawable/btn_radio_off_selected" />
<item android:state_checked="false" android:drawable="@drawable/btn_radio_off" />
<item android:state_checked="true" android:drawable="@drawable/btn_radio_on" />
</selector>

I had a similar issue when trying to access a service (old ASMX service). The call would work when accessing via an IP however when calling with an alias I would get the remote name could not be resolved.
Added the following to the config and it resolved the issue:
<system.net>
<defaultProxy enabled="true">
</defaultProxy>
</system.net>
You're apparently off by one day, exactly 86400 seconds. Use the number 2209161600 Not the number 2209075200 If you Google the two numbers, you'll find support for the above. I tried your formula but was always coming up 1 day different from my server. It's not obvious from the unix timestamp unless you think in unix instead of human time ;-) but if you double check then you'll see this might be correct.
This isn’t a solution in the sense that it doesn’t resolve the conditions which cause the message to appear in the logs, but the message can be suppressed by appending the following to conf/logging.properties
:
org.apache.catalina.webresources.Cache.level = SEVERE
This filters out the “Unable to add the resource” logs, which are at level WARNING.
In my view a WARNING
is not necessarily an error that needs to be addressed, but rather can be ignored if desired.
I normally use the HttpPostedFileBase parameter only in Mvc Controllers. When dealing with ApiControllers try checking the HttpContext.Current.Request.Files property for incoming files instead:
[HttpPost]
public string UploadFile()
{
var file = HttpContext.Current.Request.Files.Count > 0 ?
HttpContext.Current.Request.Files[0] : null;
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(
HttpContext.Current.Server.MapPath("~/uploads"),
fileName
);
file.SaveAs(path);
}
return file != null ? "/uploads/" + file.FileName : null;
}
You can use laravel MessageBag to add our own messages to existing messages.
To use MessageBag you need to use:
use Illuminate\Support\MessageBag;
In the controller:
MessageBag $message_bag
$message_bag->add('message', trans('auth.confirmation-success'));
return redirect('login')->withSuccess($message_bag);
Hope it will help some one.
You are using the wrong type. The Array(...)
function returns a Variant
, not a String
.
Thus, in the Declaration section of your module (it does not need to be a different module!), you define
Public colHeader As Variant
and somewhere at the beginning of your program code (for example, in the Workbook_Open
event) you initialize it with
colHeader = Array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L")
Another (simple) alternative would be to create a function that returns the array, e.g. something like
Public Function GetHeaders() As Variant
GetHeaders = Array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L")
End Function
This has the advantage that you do not need to initialize the global variable and the drawback that the array is created again on every function call.
Update in 2017: Hey. This is a terrible answer. Don't use it. Back in the old days this type of jQuery use was common. And it probably worked back then. Just read it, realize it's terrible, then move on (or downvote or, whatever) to one of the other answers that are better for today's jQuery.
$("input[type=radio]").change(function(){
alert( $("input[type=radio][name="+ this.name + "]").val() );
});
if you are hosted on Linux:
passthru('du -h -s ' . $DIRECTORY_PATH)
It's better than foreach

In the case where you pass -D
parameters into CMake when generating the build files and don't want to delete the entire build/ directory:
Simply delete the CMakeFiles/ directory inside your build directory.
rm -rf CMakeFiles/
cmake --build .
This causes CMake to rerun, and build system files are regenerated. Your build will also start from scratch.
BalusC's list is solid. One additional way this field frequently appears empty is when the user is behind a proxy server. This is similar to being behind a firewall but is slightly different so I wanted to mention it for the sake of completeness.
You can use the function stat.desc from pastec package.
library(pastec)
stat.desc(x, BASIC =TRUE, NORMAL =TRUE)
you can find more about it from here: https://www.rdocumentation.org/packages/pastecs/versions/1.3.21/topics/stat.desc
I had this issue, grid lines appeared to be missing on some cells.
Took me awhile to figure out that the color of those cells were white. I clicked format cell, pattern and then selected "no color" (instead of white) The the grid lines were visible again.
I hope this helps others as it took me a while to figure out why.
I prefer this process:
public class SortUtil
{
public static <T> List<T> sort(List<T> list, String sortByProperty)
{
Collections.sort(list, new BeanComparator(sortByProperty));
return list;
}
}
List<T> sortedList = SortUtil<T>.sort(unsortedList, "startDate");
If you list of objects has a property called startDate
, you call use this over and over. You can even chain them startDate.time
.
This requires your object to be Comparable
which means you need a compareTo
, equals
, and hashCode
implementation.
Yes, it could be faster... But now you don't have to make a new Comparator for each type of sort. If you can save on dev time and give up on runtime, you might go with this one.
I found a function called sleep function on the internet and don't know who made it. Here it is.
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
sleep(2000);
This one works for me
CREATE Function [dbo].[RemoveNumericCharacters](@Temp VarChar(1000))
Returns VarChar(1000)
AS
Begin
Declare @NumRange as varchar(50) = '%[0-9]%'
While PatIndex(@NumRange, @Temp) > 0
Set @Temp = Stuff(@Temp, PatIndex(@NumRange, @Temp), 1, '')
Return @Temp
End
and you can use it like so
SELECT dbo.[RemoveNumericCharacters](Name) FROM TARGET_TABLE
You have two options here, you can make it open in a new window/tab with JS:
<td onClick={()=> window.open("someLink", "_blank")}>text</td>
But a better option is to use a regular link but style it as a table cell:
<a style={{display: "table-cell"}} href="someLink" target="_blank">text</a>
If you don't like break
s and goto
s, you can use a "traditional" for loop instead the for-in, with an extra abort condition:
int a, b;
bool abort = false;
for (a = 0; a < 10 && !abort; a++) {
for (b = 0; b < 10 && !abort; b++) {
if (condition) {
doSomeThing();
abort = true;
}
}
}
Expanding on René Nyffenegger's answer, for those who do not have access to PowerShell version 6.x, we use Split Path, which doesn't test for file existence:
Split-Path "C:\Folder\SubFolder\myfile.txt" -Leaf
This returns "myfile.txt". If we know that the file name doesn't have periods in it, we can split the string and take the first part:
(Split-Path "C:\Folder\SubFolder\myfile.txt" -Leaf).Split('.') | Select -First 1
or
(Split-Path "C:\Folder\SubFolder\myfile.txt" -Leaf).Split('.')[0]
This returns "myfile". If the file name might include periods, to be safe, we could use the following:
$FileName = Split-Path "C:\Folder\SubFolder\myfile.txt.config.txt" -Leaf
$Extension = $FileName.Split('.') | Select -Last 1
$FileNameWoExt = $FileName.Substring(0, $FileName.Length - $Extension.Length - 1)
This returns "myfile.txt.config". Here I prefer to use Substring() instead of Replace() because the extension preceded by a period could also be part of the name, as in my example. By using Substring we return the filename without the extension as requested.
Your best bet is to throw
an Error
wrapping the value, which results in a rejected promise with an Error
wrapping the value:
} catch (error) {
throw new Error(400);
}
You can also just throw
the value, but then there's no stack trace information:
} catch (error) {
throw 400;
}
Alternately, return a rejected promise with an Error
wrapping the value, but it's not idiomatic:
} catch (error) {
return Promise.reject(new Error(400));
}
(Or just return Promise.reject(400);
, but again, then there's no context information.)
In your case, as you're using TypeScript
and foo
's return value is Promise<A>
, you'd use this:
return Promise.reject<A>(400 /*or Error*/ );
In an async
/await
situation, that last is probably a bit of a semantic mis-match, but it does work.
If you throw an Error
, that plays well with anything consuming your foo
's result with await
syntax:
try {
await foo();
} catch (error) {
// Here, `error` would be an `Error` (with stack trace, etc.).
// Whereas if you used `throw 400`, it would just be `400`.
}
Here is a very nice and compact way to do this, you can also change this function as your case needs:
result: 03.11.2017
//get date now function
getNowDate() {
//return string
var returnDate = "";
//get datetime now
var today = new Date();
//split
var dd = today.getDate();
var mm = today.getMonth() + 1; //because January is 0!
var yyyy = today.getFullYear();
//Interpolation date
if (dd < 10) {
returnDate += `0${dd}.`;
} else {
returnDate += `${dd}.`;
}
if (mm < 10) {
returnDate += `0${mm}.`;
} else {
returnDate += `${mm}.`;
}
returnDate += yyyy;
return returnDate;
}
If you use module with c++ code and have the same issue you could try
Build -> Refresh Linked C++ Projects
Also, you should open some file from this module and do
Build -> Make module "YourNativeLibModuleName"
simply use find tool.
find absolute_path
displays full paths on my Linux machine, while
find relative_path
will not.
You can use Toolbar inside the fragment and it is easy to handle. First add Toolbar to layout of the fragment
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:minHeight="?attr/actionBarSize"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:background="?attr/colorPrimaryDark">
</android.support.v7.widget.Toolbar>
Inside the onCreateView Method in the fragment you can handle the toolbar like this.
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
toolbar.setTitle("Title");
toolbar.setNavigationIcon(R.drawable.ic_arrow_back);
IT will set the toolbar,title and the back arrow navigation to toolbar.You can set any icon to setNavigationIcon method.
If you need to trigger any event when click toolbar navigation icon you can use this.
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//handle any click event
});
If your activity have navigation drawer you may need to open that when click the navigation back button. you can open that drawer like this.
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
drawer.openDrawer(Gravity.START);
}
});
Full code is here
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//inflate the layout to the fragement
view = inflater.inflate(R.layout.layout_user,container,false);
//initialize the toolbar
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
toolbar.setTitle("Title");
toolbar.setNavigationIcon(R.drawable.ic_arrow_back);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//open navigation drawer when click navigation back button
DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
drawer.openDrawer(Gravity.START);
}
});
return view;
}
Bit old, but doesn't hurt to add some notes.
When you write something like this
let a: any;
let b: Object;
let c: {};
And that's why
a.doSomething(); // Ok: the compiler trusts you on that
b.doSomething(); // Error: Object has no doSomething member
c.doSomething(); // Error: c neither has doSomething nor inherits it from Object
and why
a.toString(); // Ok: whatever, dude, have it your way
b.toString(); // Ok: toString is defined in Object
c.toString(); // Ok: c inherits toString from Object
So Object
and {}
are equivalents in TypeScript.
If you declare functions like these
function fa(param: any): void {}
function fb(param: Object): void {}
with the intention of accepting anything for param (maybe you're going to check types at run-time to decide what to do with it), remember that
It is worth noting, though, that if param is supposed to accept multiple known types, a better approach is to declare it using union types, as in
function fc(param: string|number): void {}
Obviously, OO inheritance rules still apply, so if you want to accept instances of derived classes and treat them based on their base type, as in
interface IPerson {
gender: string;
}
class Person implements IPerson {
gender: string;
}
class Teacher extends Person {}
function func(person: IPerson): void {
console.log(person.gender);
}
func(new Person()); // Ok
func(new Teacher()); // Ok
func({gender: 'male'}); // Ok
func({name: 'male'}); // Error: no gender..
the base type is the way to do it, not any. But that's OO, out of scope, I just wanted to clarify that any should only be used when you don't know whats coming, and for anything else you should annotate the correct type.
UPDATE:
Typescript 2.2 added an object
type, which specifies that a value is a non-primitive: (i.e. not a number
, string
, boolean
, symbol
, undefined
, or null
).
Consider functions defined as:
function b(x: Object) {}
function c(x: {}) {}
function d(x: object) {}
x
will have the same available properties within all of these functions, but it's a type error to call d
with a primitive:
b("foo"); //Okay
c("foo"); //Okay
d("foo"); //Error: "foo" is a primitive
Try something along these lines:
int divisors(int myNum) {
int limit = myNum;
int divisorCount = 0;
if (x == 1)
return 1;
for (int i = 1; i < limit; ++i) {
if (myNum % i == 0) {
limit = myNum / i;
if (limit != i)
divisorCount++;
divisorCount++;
}
}
return divisorCount;
}
assert
is for ensuring that something is true in a debug mode, without it having any effect in a release build. Better to use an if
statement and have an alternate plan for characters that are outside the range, unless the only way to get characters outside the range is through a program bug.
Also, depending on your character encoding, you might find a difference between the Unicode characters 0x80 through 0xff and their char
version.
I personally prefer to split the string by .
and just return the last array element :)
var fileExt = filename.split('.').pop();
If there is no .
in filename you get the entire string back.
Examples:
'some_value' => 'some_value'
'.htaccess' => 'htaccess'
'../images/something.cool.jpg' => 'jpg'
'http://www.w3schools.com/jsref/jsref_pop.asp' => 'asp'
'http://stackoverflow.com/questions/680929' => 'com/questions/680929'
You can use Coil library to load svg. Just add these lines in build.gradle
// ... Coil (https://github.com/coil-kt/coil)
implementation("io.coil-kt:coil:0.12.0")
implementation("io.coil-kt:coil-svg:0.12.0")
Then Add an extension function
fun AppCompatImageView.loadSvg(url: String) {
val imageLoader = ImageLoader.Builder(this.context)
.componentRegistry { add(SvgDecoder([email protected])) }
.build()
val request = ImageRequest.Builder(this.context)
.crossfade(true)
.crossfade(500)
.data(url)
.target(this)
.build()
imageLoader.enqueue(request)
}
Then call this method in your activity or fragment
your_image_view.loadSvg("your_file_name.svg")
I just copy the file name Queue.py in the */lib/python2.7/

You can include any layout file in other layout file as-
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="30dp" >
<include
android:id="@+id/frnd_img_file"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
layout="@layout/include_imagefile"/>
<include
android:id="@+id/frnd_video_file"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
layout="@layout/include_video_lay" />
<ImageView
android:id="@+id/downloadbtn"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_centerInParent="true"
android:src="@drawable/plus"/>
</RelativeLayout>
here the layout files in include tag are other .xml layout files in the same res folder.
If you really don't want to use any server controls, you should put the Response.Write
in the place you want the string to be written:
<body>
<% Response.Write(stringVariable); %>
</body>
A shorthand for this syntax is:
<body>
<%= stringVariable %>
</body>

You could include it however you'd like, but possibly in some kind of extensions.js
file at the top of your script stack.
<?php wp_make_link_relative( $link ) ?>
Convert full URL paths to relative paths.
Removes the http or https protocols and the domain. Keeps the path '/' at the beginning, so it isn't a true relative link, but from the web root base.

The recursive function is a function which calls by itself
It allows programmers to write efficient programs using a minimal amount of code.
The downside is that they can cause infinite loops and other unexpected results if not written properly.
I will explain both Simple Recursive function and Tail Recursive function

From the given example:
public static int fact(int n){

Is the deciding factor when to exit the loop
else
return n * fact(n-1);
Is the actual processing to be done

Let us see what happens internally if I run fact(4)
public static int fact(4){
if(4 <=1)
return 1;
else
return 4 * fact(4-1);
}
If
loop fails so it goes to else
loop
so it returns 4 * fact(3)
In stack memory, we have 4 * fact(3)
Substituting n=3
public static int fact(3){
if(3 <=1)
return 1;
else
return 3 * fact(3-1);
}
If
loop fails so it goes to else
loop
so it returns 3 * fact(2)
Remember we called ```4 * fact(3)``
The output for fact(3) = 3 * fact(2)
So far the stack has 4 * fact(3) = 4 * 3 * fact(2)
In stack memory, we have 4 * 3 * fact(2)
Substituting n=2
public static int fact(2){
if(2 <=1)
return 1;
else
return 2 * fact(2-1);
}
If
loop fails so it goes to else
loop
so it returns 2 * fact(1)
Remember we called 4 * 3 * fact(2)
The output for fact(2) = 2 * fact(1)
So far the stack has 4 * 3 * fact(2) = 4 * 3 * 2 * fact(1)
In stack memory, we have 4 * 3 * 2 * fact(1)
Substituting n=1
public static int fact(1){
if(1 <=1)
return 1;
else
return 1 * fact(1-1);
}
If
loop is true
so it returns 1
Remember we called 4 * 3 * 2 * fact(1)
The output for fact(1) = 1
So far the stack has 4 * 3 * 2 * fact(1) = 4 * 3 * 2 * 1
Finally, the result of fact(4) = 4 * 3 * 2 * 1 = 24
The Tail Recursion would be
public static int fact(x, running_total=1) {
if (x==1) {
return running_total;
} else {
return fact(x-1, running_total*x);
}
}
public static int fact(4, running_total=1) {
if (x==1) {
return running_total;
} else {
return fact(4-1, running_total*4);
}
}
If
loop fails so it goes to else
loop
so it returns fact(3, 4)
In stack memory, we have fact(3, 4)
Substituting n=3
public static int fact(3, running_total=4) {
if (x==1) {
return running_total;
} else {
return fact(3-1, 4*3);
}
}
If
loop fails so it goes to else
loop
so it returns fact(2, 12)
In stack memory, we have fact(2, 12)
Substituting n=2
public static int fact(2, running_total=12) {
if (x==1) {
return running_total;
} else {
return fact(2-1, 12*2);
}
}
If
loop fails so it goes to else
loop
so it returns fact(1, 24)
In stack memory, we have fact(1, 24)
Substituting n=1
public static int fact(1, running_total=24) {
if (x==1) {
return running_total;
} else {
return fact(1-1, 24*1);
}
}
If
loop is true
so it returns running_total
The output for running_total = 24
Finally, the result of fact(4,1) = 24
In Kotlin I have created an extension function for the Context. It takes a @StringRes and optionally you can provide parameters as well.
fun Context.fromHtmlWithParams(@StringRes stringRes: Int, parameter : String? = null) : Spanned {
val stringText = if (parameter.isNullOrEmpty()) {
this.getString(stringRes)
} else {
this.getString(stringRes, parameter)
}
return Html.fromHtml(stringText, Html.FROM_HTML_MODE_LEGACY)
}
Usage
tv_directors.text = context?.fromHtmlWithParams(R.string.directors, movie.Director)
Just Use
import qs from "qs";
let data = {
'profileId': this.props.screenProps[0],
'accountId': this.props.screenProps[1],
'accessToken': this.props.screenProps[2],
'itemId': this.itemId
};
return axios.post(METHOD_WALL_GET, qs.stringify(data))
Redis is an in memory data store, that can persist it's state to disk (to enable recovery after restart). However, being an in-memory data store means the size of the data store (on a single node) cannot exceed the total memory space on the system (physical RAM + swap space). In reality, it will be much less that this, as Redis is sharing that space with many other processes on the system, and if it exhausts the system memory space it will likely be killed off by the operating system.
Mongo is a disk based data store, that is most efficient when it's working set fits within physical RAM (like all software). Being a disk based data means there are no intrinsic limits on the size of a Mongo database, however configuration options, available disk space, and other concerns may mean that databases sizes over a certain limit may become impractical or inefficient.
Both Redis and Mongo can be clustered for high availability, backup and to increase the overall size of the datastore.
Since this is a popular question, I would like to add that in Elasticsearch version 2 things changed a bit.
Instead of filtered
query, one should use bool
query in the top level.
If you don't care about the score of must
parts, then put those parts into filter
key. No scoring means faster search. Also, Elasticsearch will automatically figure out, whether to cache them, etc. must_not
is equally valid for caching.
Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html
Also, mind that "gte": "now"
cannot be cached, because of millisecond granularity. Use two ranges in a must
clause: one with now/1h
and another with now
so that the first can be cached for a while and the second for precise filtering accelerated on a smaller result set.
simply multiplying by -1 works in both ways ...
>>> -10 * -1
10
>>> 10 * -1
-10
All data about topics and its partitions are stored in tmp/kafka-logs/
. Moreover they are stored in a format topic-partionNumber
, so if you want to delete a topic newTopic
, you can:
rm -rf /tmp/kafka-logs/newTopic-*
Note that ≪Copy all as HAR≫ does not contain response body.
You can get response body via ≪Save as HAR with Content≫, but it breaks if you have any more than a trivial amount of logs (I tried once with only 8k requests and it doesn't work.) To solve this, you can script an output yourself using _request.contentData()
.
When there's too many logs, even _request.contentData()
and ≪Copy response≫ would fail, hopefully they would fix this problem. Until then, inspecting any more than a trivial amount of network logs cannot be properly done with Chrome Network Inspector and its best to use another tool.
I assume you mean struct and not strict, but on a 32-bit system it'll be either 5 or 8 bytes, depending on if the compiler is padding the struct.
Here is my subroutine approach to this problem. it transforms an integer in the range 0 : 9999 as a character. For example, the INTEGER 123 is transformed into the character 0123. hope it helps.
P.S. - sorry for the comments; they make sense in Romanian :P

include.prepload.js file will have a line something like below. probably as the last line.
//# sourceMappingURL=include.prepload.js.map
Delete it and the error will go away.
First We Need To Write into our Memory Stream and then with the help of Memory Stream method "WriteTo" we can write to the Response of the Page as shown in the below code.
MemoryStream filecontent = null;
filecontent =//CommonUtility.ExportToPdf(inputXMLtoXSLT);(This will be your MemeoryStream Content)
Response.ContentType = "image/pdf";
string headerValue = string.Format("attachment; filename={0}", formName.ToUpper() + ".pdf");
Response.AppendHeader("Content-Disposition", headerValue);
filecontent.WriteTo(Response.OutputStream);
Response.End();
FormName is the fileName given,This code will make the generated PDF file downloadable by invoking a PopUp.

string currentdatetime = DateTime.Now.ToString("dd'/'MM'/'yyyy");
you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.
<script type="text/javascript">
$(document).ready(function(){
$("#formID").validate({
rules :{
"data[User][name]" : {
required : true
}
},
messages :{
"data[User][name]" : {
required : 'Enter username'
}
}
});
});
</script>
You can see required : true
same there is many more property like for email you can define email : true
for number number : true
To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
If you care for it to be in the same order as before you can use a common table expression for that:
;WITH CTE AS (
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
)
SELECT *
FROM CTE
ORDER BY MySortColumn
I think this is related, but I had a problem when building directly using msbuild
command line (from a batch file) vs building from within VS.
Using something like the following:
<PostBuildEvent>
MOVE /Y "$(TargetDir)something.file1" "$(ProjectDir)something.file1"
start XCOPY /Y /R "$(SolutionDir)SomeConsoleApp\bin\$(ConfigurationName)\*" "$(ProjectDir)App_Data\Consoles\SomeConsoleApp\"
</PostBuildEvent>
(note: start XCOPY
rather than XCOPY
used to get around a permissions issue which prevented copying)
The macro $(SolutionDir)
evaluated to ..\
when executing msbuild from a batchfile, which resulted in the XCOPY
command failing. It otherwise worked fine when built from within Visual Studio. Confirmed using /verbosity:diagnostic
to see the evaluated output.
Using the macro $(ProjectDir)..\
instead, which amounts to the same thing, worked fine and retained the full path in both build scenarios.
First I recommend you as @ChrisHuang-Leaver suggested to define a new file with all the choices you need it there, like choices.py
:
STATUS_CHOICES = (
(1, _("Not relevant")),
(2, _("Review")),
(3, _("Maybe relevant")),
(4, _("Relevant")),
(5, _("Leading candidate"))
)
RELEVANCE_CHOICES = (
(1, _("Unread")),
(2, _("Read"))
)
Now you need to import them on the models, so the code is easy to understand like this(models.py):
from myApp.choices import *
class Profile(models.Model):
user = models.OneToOneField(User)
status = models.IntegerField(choices=STATUS_CHOICES, default=1)
relevance = models.IntegerField(choices=RELEVANCE_CHOICES, default=1)
And you have to import the choices in the forms.py too:
forms.py:
from myApp.choices import *
class CViewerForm(forms.Form):
status = forms.ChoiceField(choices = STATUS_CHOICES, label="", initial='', widget=forms.Select(), required=True)
relevance = forms.ChoiceField(choices = RELEVANCE_CHOICES, required=True)
Anyway you have an issue with your template, because you're not using any {{form.field}}
, you generate a table but there is no inputs only hidden_fields.
When the user is staff you should generate as many input fields as users you can manage. I think django form is not the best solution for your situation.
I think it will be better for you to use html form, so you can generate as many inputs using the boucle: {% for user in users_list %}
and you generate input with an ID related to the user, and you can manage all of them in the view.
Better than all above is ever to use Standard C specification for struct initialization:
struct StructType structVar = {0};
Here are all bits zero (ever).

There is a Mongoose plugin available on NPM called mongoose-file. It lets you add a file field to a Mongoose Schema for file upload. I have never used it but it might prove useful. If the images are very small you could Base64 encode them and save the string to the database.
Storing some small (under 1MB) files with MongoDB in NodeJS WITHOUT GridFS
Simple and neet : use vw
units for a responsive height/width according to the viewport width.
vw : 1/100th of the width of the viewport. (Source MDN)
HTML:
<div></div>
CSS for a 1:1 aspect ratio:
div{
width:80vw;
height:80vw; /* same as width */
}
Table to calculate height according to the desired aspect ratio and width of element.
aspect ratio | multiply width by
-----------------------------------
1:1 | 1
1:3 | 3
4:3 | 0.75
16:9 | 0.5625
This technique allows you to :
position:absolute;
These units are supported by IE9+ see canIuse for more info
An alternative is to normalize the data. Below are three sets of data with widely varying ranges. In the top chart you can see the variation in one series clearly, in another not so clearly, and the third not at all.
In the second range, I have adjusted the series names to include the data range, using this formula in cell C15 and copying it to D15:E15
=C2&" ("&MIN(C3:C9)&" to "&MAX(C3:C9)&")"
I have normalized the values in the data range using this formula in C15 and copying it to the entire range C16:E22
=100*(C3-MIN(C$3:C$9))/(MAX(C$3:C$9)-MIN(C$3:C$9))
In the second chart, you can see a pattern: all series have a low in January, rising to a high in March, and dropping to medium-low value in June or July.
You can modify the normalizing formula however you need:
=100*C3/MAX(C$3:C$9)
=C3/MAX(C$3:C$9)
=(C3-AVERAGE(C$3:C$9))/STDEV(C$3:C$9)
etc.
One simple possibility would be to make an array of 26 ints, each is a count for a letter a-z:
int alphacount[26] = {0}; //[0] = 'a', [1] = 'b', etc
Then loop through the string and increment the count for each letter:
for(int i = 0; i<strlen(mystring); i++) //for the whole length of the string
if(isalpha(mystring[i]))
alphacount[tolower(mystring[i])-'a']++; //make the letter lower case (if it's not)
//then use it as an offset into the array
//and increment
It's a simple idea that works for A-Z, a-z. If you want to separate by capitals you just need to make the count 52 instead and subtract the correct ASCII offset
ubar jar is also known as fat jar i.e. jar with dependencies.
There are three common methods for constructing an uber jar:
Ok, there already is an accepted answer but I think there is a better way to do it, you just have to had a new layer a bit larger than your view and do not mask it to the bounds of the view's layer (which actually is the default behaviour). Here is the sample code :
CALayer * externalBorder = [CALayer layer];
externalBorder.frame = CGRectMake(-1, -1, myView.frame.size.width+2, myView.frame.size.height+2);
externalBorder.borderColor = [UIColor blackColor].CGColor;
externalBorder.borderWidth = 1.0;
[myView.layer addSublayer:externalBorder];
myView.layer.masksToBounds = NO;
Of course this is if you want your border to be 1 unity large, if you want more you adapt the borderWidth
and the frame of the layer accordingly.
This is better than using a second view a bit larger as a CALayer
is lighter than a UIView
and you don't have do modify the frame of myView
, which is good for instance if myView
is aUIImageView
N.B : For me the result was not perfect on simulator (the layer was not exactly at the right position so the layer was thicker on one side sometimes) but was exactly what is asked for on real device.
EDIT
Actually the problem I talk about in the N.B was just because I had reduced the screen of the simulator, on normal size there is absolutely no issue
Hope it helps
Lists are slightly faster than sets when you just want to iterate over the values.
Sets, however, are significantly faster than lists if you want to check if an item is contained within it. They can only contain unique items though.
It turns out tuples perform in almost exactly the same way as lists, except for their immutability.
Iterating

... for i in iterable:

Use Pattern and Matcher
public class Chk {
public static void main(String[] args) {
String s = "test string (67)";
ArrayList<String> arL = new ArrayList<String>();
ArrayList<String> inL = new ArrayList<String>();
Pattern pat = Pattern.compile("\\(\\w+\\)");
Matcher mat = pat.matcher(s);
while (mat.find()) {
arL.add(mat.group());
System.out.println(mat.group());
}
for (String sx : arL) {
Pattern p = Pattern.compile("(\\w+)");
Matcher m = p.matcher(sx);
while (m.find()) {
inL.add(m.group());
System.out.println(m.group());
}
}
System.out.println(inL);
}
}
Wrap your all statements in !IsPostBack
condition on page load.
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
// all statements
}
}
This will fix your issue.
Addition to @jwize's answer
Because angular.element(document).injector()
was giving error injector is not defined
So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.
function compileAngularElement( elSelector) {
var elSelector = (typeof elSelector == 'string') ? elSelector : null ;
// The new element to be added
if (elSelector != null ) {
var $div = $( elSelector );
// The parent of the new element
var $target = $("[ng-app]");
angular.element($target).injector().invoke(['$compile', function ($compile) {
var $scope = angular.element($target).scope();
$compile($div)($scope);
// Finally, refresh the watch expressions in the new element
$scope.$apply();
}]);
}
}
use it by passing just new element's selector. like this
compileAngularElement( '.user' ) ;
There are already multiple answers and formatting types for SQL server 2008. But this method somewhat ambiguous and it would be difficult for you to remember the number with respect to Specific Date Format. That's why in next versions of SQL server there is better option.
FORMAT ( value, format [, culture ] )
With culture option, you can specify date as per your viewers.
DECLARE @d DATETIME = '10/01/2011';
SELECT FORMAT ( @d, 'd', 'en-US' ) AS 'US English Result'
,FORMAT ( @d, 'd', 'en-gb' ) AS 'Great Britain English Result'
,FORMAT ( @d, 'd', 'de-de' ) AS 'German Result'
,FORMAT ( @d, 'd', 'zh-cn' ) AS 'Simplified Chinese (PRC) Result';
SELECT FORMAT ( @d, 'D', 'en-US' ) AS 'US English Result'
,FORMAT ( @d, 'D', 'en-gb' ) AS 'Great Britain English Result'
,FORMAT ( @d, 'D', 'de-de' ) AS 'German Result'
,FORMAT ( @d, 'D', 'zh-cn' ) AS 'Chinese (Simplified PRC) Result';
US English Result Great Britain English Result German Result Simplified Chinese (PRC) Result
---------------- ----------------------------- ------------- -------------------------------------

For OP's solution, we can use following format, which is already mentioned by @Martin Smith:
FORMAT(GETDATE(), 'dd/MMM/yyyy', 'en-us')
Some sample date formats:
If you want more date formats of SQL server, you should visit:
UTF-8 is a multibyte encoding that can represent any Unicode character. ISO 8859-1 is a single-byte encoding that can represent the first 256 Unicode characters. Both encode ASCII exactly the same way.
$('inputFile').parent().parent().children('td > label').hide();
can help you navigate two levels up ( to TD, to TR ) moving two levels back down ( all TD's in that TR and their LABEL tags ), applying the hide() function there.
if you want to stay at the TR level and hide them:
$('inputFile').parent().parent().hide();
… is sufficient.
you can navigate very easily through the elements using the jquery selectors.
parent is documented here: http://api.jquery.com/parent/
hide is documented here: http://api.jquery.com/hide/
You might find Perl or Python useful to get data from the serial port. To send data to the server, the solution could be easy if the server is (let's say) an HTTP application or even a popular database. The solution would be not so easy if it is some custom/proprietary TCP application.
Make sure you've added first, and then commit/ push:
Like:
git init
git add .
git commit -m "message"
git remote add origin "github.com/your_repo.git"
git push -u origin master
Just for the sake of completeness, I would suggest using the InnerHTML way as well - even though I would not call it the best way...
document.getElementById("image-holder").innerHTML = "<img src='image.png' alt='The Image' />";
By the way, innerHTML is not that bad
In the example you gave, there is no difference, in terms of output, between append
and +=
. But there is a difference between append
and +
(which the question originally asked about).
>>> a = []
>>> id(a)
11814312
>>> a.append("hello")
>>> id(a)
11814312
>>> b = []
>>> id(b)
11828720
>>> c = b + ["hello"]
>>> id(c)
11833752
>>> b += ["hello"]
>>> id(b)
11828720
As you can see, append
and +=
have the same result; they add the item to the list, without producing a new list. Using +
adds the two lists and produces a new list.
I had this issue and I realized that .gitignore file is changed. So, I changed .gitignore and I could pull the changes.
try
CREATE TABLE [dbo].[Names]
(
[Name] [nvarchar](64) NOT NULL,
[CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
[UpdateTS] [smalldatetime] NOT NULL
)
PS I think a smalldatetime is good enough. You may decide differently.
Can you not do this at the "moment of impact" ?
In Sql Server, this is common:
Update dbo.MyTable
Set
ColA = @SomeValue ,
UpdateDS = CURRENT_TIMESTAMP
Where...........
Sql Server has a "timestamp" datatype.
But it may not be what you think.
Here is a reference:
http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx
Here is a little RowVersion (synonym for timestamp) example:
CREATE TABLE [dbo].[Names]
(
[Name] [nvarchar](64) NOT NULL,
RowVers rowversion ,
[CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
[UpdateTS] [datetime] NOT NULL
)
INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Update dbo.Names Set Name = Name
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Maybe a complete working example:
DROP TABLE [dbo].[Names]
GO
CREATE TABLE [dbo].[Names]

Matching on the "Name" value is probably not wise.

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS
BEGIN
UPDATE dbo.Names
SET UpdateTS = CURRENT_TIMESTAMP
From dbo.Names myAlias
WHERE exists ( select null from inserted triggerInsertedTable where myAlias.SurrogateKey = triggerInsertedTable.SurrogateKey)
END
GO
INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */
select * , ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]
The other answers are entirely correct, but this answer provides some extra detalis, I think.
Consider this example:
using System;
static class Program {
static void Main() {
try {
ThrowTest();
} catch (Exception e) {
Console.WriteLine("Your stack trace:");
Console.WriteLine(e.StackTrace);
Console.WriteLine();
if (e.InnerException == null) {
Console.WriteLine("No inner exception.");
} else {
Console.WriteLine("Stack trace of your inner exception:");
Console.WriteLine(e.InnerException.StackTrace);
}
}
}
static void ThrowTest() {
decimal a = 1m;
decimal b = 0m;
try {
Mult(a, b); // line 34
Div(a, b); // line 35
Mult(b, a); // line 36
Div(b, a); // line 37
} catch (ArithmeticException arithExc) {
Console.WriteLine("Handling a {0}.", arithExc.GetType().Name);
// uncomment EITHER
//throw arithExc;
// OR
//throw;
// OR
//throw new Exception("We handled and wrapped your exception", arithExc);
}
}
static void Mult(decimal x, decimal y) {
decimal.Multiply(x, y);
}
static void Div(decimal x, decimal y) {
decimal.Divide(x, y);
}
}
If you uncomment the throw arithExc;
line, your output is:
Handling a DivideByZeroException.
Your stack trace:
at Program.ThrowTest() in c:\somepath\Program.cs:line 44
at Program.Main() in c:\somepath\Program.cs:line 9
No inner exception.
Certainly, you have lost information about where that exception happened. If instead you use the throw;
line, this is what you get:
Handling a DivideByZeroException.
Your stack trace:
at System.Decimal.FCallDivide(Decimal& d1, Decimal& d2)
at System.Decimal.Divide(Decimal d1, Decimal d2)
at Program.Div(Decimal x, Decimal y) in c:\somepath\Program.cs:line 58
at Program.ThrowTest() in c:\somepath\Program.cs:line 46
at Program.Main() in c:\somepath\Program.cs:line 9
No inner exception.
This is a lot better, because now you see that it was the Program.Div
method that caused you problems. But it's still hard to see if this problem comes from line 35 or line 37 in the try
block.
If you use the third alternative, wrapping in an outer exception, you lose no information:
Handling a DivideByZeroException.
Your stack trace:
at Program.ThrowTest() in c:\somepath\Program.cs:line 48
at Program.Main() in c:\somepath\Program.cs:line 9
Stack trace of your inner exception:
at System.Decimal.FCallDivide(Decimal& d1, Decimal& d2)
at System.Decimal.Divide(Decimal d1, Decimal d2)
at Program.Div(Decimal x, Decimal y) in c:\somepath\Program.cs:line 58
at Program.ThrowTest() in c:\somepath\Program.cs:line 35
In particular you can see that it's line 35 that leads to the problem. However, this requires people to search the InnerException
, and it feels somewhat indirect to use inner exceptions in simple cases.
In this blog post they preserve the line number (line of the try block) by calling (through reflection) the internal
intance method InternalPreserveStackTrace()
on the Exception
object. But it's not nice to use reflection like that (the .NET Framework might change their internal
members some day without warning).
Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:
Sub FilterAndCopy()
Dim LastRow As Long
Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
.Range("$A:$E").AutoFilter
.Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
.Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
.Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
.Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
.Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub
As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.
When calling the function, follow it by return false
example:
<input type="submit" value="Add" onclick="addNewPayment();return false;">
Such difference between the output of du -sh
and df -h
may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted
to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.
There is an odd case I got in VS2017, about the space between ‘Any’ and 'CPU'. this is not about using command prompt.
If you have a build project file, which could call other solution files. You can try to add the space between Any and CPU, like this (the Platform property value):
<MSBuild Projects="@(SolutionToBuild2)" Properties ="Configuration=$(ProjectConfiguration);Platform=Any CPU;Rerun=$(MsBuildReRun);" />
Before I fix this build issue, it is like this (ProjectPlatform is a global variable, was set to 'AnyCPU'):
<MSBuild Projects="@(SolutionToBuild1)" Properties ="Configuration=$(ProjectConfiguration);Platform=$(ProjectPlatform);Rerun=$(MsBuildReRun);" />
Also, we have a lot projects being called using $ (ProjectPlatform), which is 'AnyCPU' and work fine. If we open proj file, we can see lines liket this and it make sense.
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'">
So my conclusion is, 'AnyCPU' works for calling project files, but not for calling solution files, for calling solution files, using 'Any CPU' (add the space.)
For now, I am not sure if it is a bug of VS project file or MSBuild. I am using VS2017 with VS2017 build tools installed.
Maybe not as elegant but another possibility would be to write a formula to do the check and fill it in an adjacent column. You could then filter on that column.
The following looks in cell b14 and would return true for all the file types you mention. This assumes that the file extension is by itself in the column. If it's not it would be a little more complicated but you could still do it this way.
=OR(B14=".pdf",B14=".doc",B14=".docx",B14=".xls",B14=".xlsx",B14=".rtf",B14=".txt",B14=".csv",B14=".pps")
Like I said, not as elegant as the advanced filters but options are always good.

Solution with greedy approach in java is as below :
public class CoinChange {
public static void main(String args[]) {
int denominations[] = {1, 5, 10, 25};
System.out.println("Total required coins are " + greeadApproach(53, denominations));
}
public static int greeadApproach(int amount, int denominations[]) {
int cnt[] = new int[denominations.length];
for (int i = denominations.length-1; amount > 0 && i >= 0; i--) {
cnt[i] = (amount/denominations[i]);
amount -= cnt[i] * denominations[i];
}
int noOfCoins = 0;
for (int cntVal : cnt) {
noOfCoins+= cntVal;
}
return noOfCoins;
}
}
But this works for single amount. If you want to run it for range, than we have to call it for each amount of range.
You need to add "(/\d+/g)" which will remove all non-number text, but it will still be a string at this point. If you create a variable and "parseInt" through the match, you can set the new variables to the array values. Here is an example of how I got it to work:
var color = $( this ).css( "background-color" );
var r = parseInt(color.match(/\d+/g)[0]);
var g = parseInt(color.match(/\d+/g)[1]);
var b = parseInt(color.match(/\d+/g)[2]);
Clone target repository same way like you cloning any other project:
git clone [email protected]:myuser/foo.git
Then install it in develop mode:
cd foo
pip install -e .
You can change anything you wan't and every code using foo
package will use modified code.
There 2 benefits ot this solution:
.git
dir, so it's regular Git repository. You can push to your fork right away.Use numpy.asscalar to convert a numpy array / matrix a scalar value:
>>> a=numpy.array([[[[42]]]])
>>> numpy.asscalar(a)
42
The output data type is the same type returned by the input’s
item
method.
It has built in error-checking if there is more than an single element:
>>> a=numpy.array([1, 2])
>>> numpy.asscalar(a)
gives:
ValueError: can only convert an array of size 1 to a Python scalar
Note: the object passed to asscalar
must respond to item
, so passing a list or tuple won't work.
1st of all, when you declare a variable in java, you should declare it using Interfaces even if you specify the implementation when instantiating it
ArrayList<ArrayList<String>> listOfLists = new ArrayList<ArrayList<String>>();
should be written
List<List<String>> listOfLists = new ArrayList<List<String>>(size);
Then you will have to instantiate all columns of your 2d array
for(int i = 0; i < size; i++) {
listOfLists.add(new ArrayList<String>());
}
And you will use it like this :
listOfLists.get(0).add("foobar");
But if you really want to "create a 2D array that each cell is an ArrayList!"
Then you must go the dijkstra way.
There has been many helpful answers here, generally culminating into two points.
AND as @MichaelBerkowski said
Backticks are to be used for table and column identifiers, but are only necessary when the identifier is a
MySQL
reserved keyword, or when the identifier contains whitespace characters or characters beyond a limited set (see below) It is often recommended to avoid using reserved keywords as column or table identifiers when possible, avoiding the quoting issue.
There is a case though where an identifier can neither be a reserved keyword or contain whitespace or characters beyond limited set but necessarily require backticks around them.
EXAMPLE
123E10
is a valid identifier name but also a valid INTEGER
literal.
[Without going into detail how you would get such an identifier name], Suppose I want to create a temporary table named 123456e6
.
No ERROR on backticks.
DB [XXX]> create temporary table `123456e6` (`id` char (8));
Query OK, 0 rows affected (0.03 sec)
ERROR when not using backticks.
DB [XXX]> create temporary table 123451e6 (`id` char (8));
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '123451e6 (`id` char (8))' at line 1
However, 123451a6
is a perfectly fine identifier name (without back ticks).
DB [XXX]> create temporary table 123451a6 (`id` char (8));
Query OK, 0 rows affected (0.03 sec)
This is completely because 1234156e6
is also an exponential number.
Updated Answer
As of June11, 2018 it is now mandatory to have a billing account to get API key. You can still make keyless calls to the Maps JavaScript API and Street View Static API which will return low-resolution maps that can be used for development. Enabling billing still gives you $200 free credit monthly for your projects.
This answer is no longer valid
As long as you're using a testing API key it is free to register and use. But when you move your app to commercial level you have to pay for it. When you enable billing, google gives you $200 credit free each month that means if your app's map usage is low you can still use it for free even after the billing enabled, if it exceeds the credit limit now you have to pay for it.
