Those look much like Bonjour / mDNS requests to me. Those packets use multicast IP address 224.0.0.251 and port 5353.
The most likely source for this is Apple iTunes, which comes pre-installed on Mac computers (and is a popular install on Windows machines as well). Apple iTunes uses it to discover other iTunes-compatible devices in the same WiFi network.
mDNS is also used (primarily by Apple's Mac and iOS devices) to discover mDNS-compatible devices such as printers on the same network.
If this is a Linux box instead, it's probably the Avahi daemon then. Avahi is ZeroConf/Bonjour compatible and installed by default, but if you don't use DNS-SD or mDNS, it can be disabled.
You have to do:
git branch <branch_name> <commit>
(you were interchanging the branch name and commit)
Or you can do:
git checkout -b <branch_name> <commit>
If in place of you use branch name, you get a branch out of tip of the branch.
go to you build.gradle (app level)
and replace the word "compile" by "implementation"
it will work 100%
Here's a simplified function that will read in bytes and create a string. It assumes you probably already know what encoding the file is in (and otherwise defaults).
static final int BUFF_SIZE = 2048;
static final String DEFAULT_ENCODING = "utf-8";
public static String readFileToString(String filePath, String encoding) throws IOException {
if (encoding == null || encoding.length() == 0)
encoding = DEFAULT_ENCODING;
StringBuffer content = new StringBuffer();
FileInputStream fis = new FileInputStream(new File(filePath));
byte[] buffer = new byte[BUFF_SIZE];
int bytesRead = 0;
while ((bytesRead = fis.read(buffer)) != -1)
content.append(new String(buffer, 0, bytesRead, encoding));
fis.close();
return content.toString();
}
a negative index will count from the end of the list, so:
num_list[-9:]

Standard UITableViewCell already contains UIImageView that appears to the left to all your labels if its image is set. You can access it using imageView property:
cell.imageView.image = someImage;
If for some reason standard behavior does not suit your needs (note that you can customize properties of that standard image view) then you can add your own UIImageView to the cell as Aman suggested in his answer. But in that approach you'll have to manage cell's layout yourself (e.g. make sure that cell labels do not overlap image). And do not add subviews to the cell directly - add them to cell's contentView:
// DO NOT!
[cell addSubview:imv];
// DO:
[cell.contentView addSubview:imv];
If you need to order your code into namespaces, just use the keyword namespace
:
file1.php
namespace foo\bar;
In file2.php
$obj = new \foo\bar\myObj();
You can also use use
. If in file2 you put
use foo\bar as mypath;
you need to use mypath
instead of bar
anywhere in the file:
$obj = new mypath\myObj();
Using use foo\bar;
is equal to use foo\bar as bar;
.
Create directory [your.project.name] in workspace root directory of your project.
Copy *.java from "src" to that directory.
Close and reopen project.
You can use Jquery's on method and listen for the scroll

To give a partial answer my own question, here is a working sample for HTML5 browsers:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="http://code.angularjs.org/1.0.0rc10/angular-1.0.0rc10.js"></script>
<script>
angular.module('myApp', [], function($locationProvider) {
$locationProvider.html5Mode(true);
});
function QueryCntl($scope, $location) {
$scope.target = $location.search()['target'];
}
</script>
</head>
<body ng-controller="QueryCntl">
Target: {{target}}<br/>
</body>
</html>
The key was to call $locationProvider.html5Mode(true);
as done above. It now works when opening http://127.0.0.1:8080/test.html?target=bob
. I'm not happy about the fact that it won't work in older browsers, but I might use this approach anyway.
An alternative that would work with older browsers would be to drop the html5mode(true)
call and use the following address with hash+slash instead:
http://127.0.0.1:8080/test.html#/?target=bob
The relevant documentation is at Developer Guide: Angular Services: Using $location (strange that my google search didn't find this...).
When you define concatenation you need to use an ALIAS for the new column if you want to order on it combined with DISTINCT Some Ex with sql 2008
--this works
SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName
from SalesLT.Customer c
order by FullName
--this works too
SELECT DISTINCT (c.FirstName + ' ' + c.LastName)
from SalesLT.Customer c
order by 1
-- this doesn't
SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName
from SalesLT.Customer c
order by c.FirstName, c.LastName
-- the problem the DISTINCT needs an order on the new concatenated column, here I order on the singular column
-- this works
SELECT DISTINCT (c.FirstName + ' ' + c.LastName)
as FullName, CustomerID
from SalesLT.Customer c
order by 1, CustomerID
-- this doesn't
SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName
from SalesLT.Customer c
order by 1, CustomerID
I know that this question is old but i would like to contribute too:
The main difference between others responses is the hashmap return.
@GetMapping("...")
@ResponseBody
public Map<String, Object> endPointExample(...) {
Map<String, Object> rtn = new LinkedHashMap<>();
rtn.put("pic", image);
rtn.put("potato", "King Potato");
return rtn;
}
This will return:
{"pic":"a17fefab83517fb...beb8ac5a2ae8f0449","potato":"King Potato"}
In addition to all the excellent answers here, newer versions of matplotlib
and pylab
can automatically determine where to put the legend without interfering with the plots, if possible.
pylab.legend(loc='best')
This will automatically place the legend away from the data if possible!
However, if there is no place to put the legend without overlapping the data, then you'll want to try one of the other answers; using loc="best"
will never put the legend outside of the plot.
#include <stdio.h>
int main() {
int c;
while((c = getchar()) != EOF) {
putchar(c);
}
printf("%d at EOF\n", c);
}
modified the above code to give more clarity on EOF, Press Ctrl+d and putchar is used to print the char avoid using printf within while loop.
Unchecked all Device orientation and checked only "Requires full screen". Its working properly
First I struggled a bit with a
DELETE FROM ... USING ... WHERE query,...
Since i wanted to test first
so i tried with SELECT FROM ... USING... WHERE ...
and this caused an error , ...
Then i wanted to reduce the number of deletions adding
LIMIT 10
which also produced an error
Then i removed the "LIMIT" and - hurray - it worked:
"1867 rows deleted. (Query took 1.3025 seconds.)"
The query was:
DELETE FROM tableX
USING tableX , tableX as Dup
WHERE NOT tableX .id = Dup.id
AND tableX .id > Dup.id
AND tableX .email= Dup.email
AND tableX .mobil = Dup.mobil
This worked.
Here I want to suggest steps to create simple plugin with arguments.
(function($) {_x000D_
$.fn.myFirstPlugin = function(options) {_x000D_
// Default params_x000D_
var params = $.extend({_x000D_
text : 'Default Title',_x000D_
fontsize : 10,_x000D_
}, options);_x000D_
return $(this).text(params.text);_x000D_
}_x000D_
}(jQuery));_x000D_
_x000D_
$('.cls-title').myFirstPlugin({ text : 'Argument Title' });
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<h1 class="cls-title"></h1>
_x000D_
Here, we have added default object called params
and set default values of options using extend
function. Hence, If we pass blank argument then it will set default values instead otherwise it will set.

Juts to follow up on what Andy Hume and others have said:
The '()' surrounding the anonymous function is the 'grouping operator' as defined in section 11.1.6 of the ECMA spec: http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf.
Taken verbatim from the docs:
11.1.6 The Grouping Operator
The production PrimaryExpression : ( Expression ) is evaluated as follows:
In this context the function is treated as an expression.
ng-bind has one-way data binding ($scope --> view). It has a shortcut {{ val }}
which displays the scope value $scope.val
inserted into html where val
is a variable name.
ng-model is intended to be put inside of form elements and has two-way data binding ($scope --> view and view --> $scope) e.g. <input ng-model="val"/>
.
Ternary operator should do nicely here: condition ? first_expression : second_expression;
strLevel = !Convert.IsDBNull(rsData["usr.ursrdaystime"]) ? Convert.ToString(rsData["usr.ursrdaystime"]) : null
I ran into a similar problem where Visual Studio (2017) said it could not find my project's PDB file. I could see the PDB file did exist in the correct path. I had to Clean and Rebuild the project, then Visual Studio recognized the PDB file and debugging worked.
We have to consider the orientation of device too:
CGFloat screenHeight;
// it is important to do this after presentModalViewController:animated:
if ([[UIApplication sharedApplication] statusBarOrientation] == UIDeviceOrientationPortrait || [[UIApplication sharedApplication] statusBarOrientation] == UIDeviceOrientationPortraitUpsideDown){
screenHeight = [UIScreen mainScreen].applicationFrame.size.height;
}
else{
screenHeight = [UIScreen mainScreen].applicationFrame.size.width;
}
If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide()
, with additional arguments, as follows:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this).hide('slide',{direction:'right'},1000);
});
});
Without using jQuery UI, you could achieve your aim just using animate()
:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this)
.animate(
{
'margin-left':'1000px'
// to move it towards the right and, probably, off-screen.
},1000,
function(){
$(this).slideUp('fast');
// once it's finished moving to the right, just
// removes the the element from the display, you could use
// `remove()` instead, or whatever.
}
);
});
});
If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js
A modified version of @nickf code:
function addhttp($url) {
if (!preg_match("~^(?:f|ht)tps?://~i", $url)) {
$url = "http://" . $url;
}
return $url;
}
Recognizes ftp://
, ftps://
, http://
and https://
in a case insensitive way.
This is the simplest way
np.random.uniform(start,stop,(rows,columns))
You can use JSON.stringify(object)
with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array))
, which is the following code (more detail can be found on this answer):
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
}
To make it more generic, you can override the JSON.stringify
function and you won't have to worry about it again, to do this, just paste this at the top of your page:
// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
};
var oldJSONStringify = JSON.stringify;
JSON.stringify = function(input){
return oldJSONStringify(convArrToObj(input));
};
})();
And now JSON.stringify
will accept arrays
or objects
! (link to jsFiddle with example)
Edit:
Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array)
always returns []
, which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify
with an object
):
(function(){
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
};
var oldJSONStringify = JSON.stringify;
JSON.stringify = function(input){
if(oldJSONStringify(input) == '[]')
return oldJSONStringify(convArrToObj(input));
else
return oldJSONStringify(input);
};
})();
success
is the callback that is invoked when the request is successful and is part of the $.ajax
call. done
is actually part of the jqXHR
object returned by $.ajax()
, and replaces success
in jQuery 1.8.
UPDATE some_table SET some_field = REPLACE(some_field, '<', '<')
findIndex
retrieves only the first index which matches callback output. You can implement your own findIndexes
by extending Array , then casting your arrays to the new structure .
class EnhancedArray extends Array {_x000D_
findIndexes(where) {_x000D_
return this.reduce((a, e, i) => (where(e, i) ? a.concat(i) : a), []);_x000D_
}_x000D_
}_x000D_
/*----Working with simple data structure (array of numbers) ---*/_x000D_
_x000D_
//existing array_x000D_
let myArray = [1, 3, 5, 5, 4, 5];_x000D_
_x000D_
//cast it :_x000D_
myArray = new EnhancedArray(...myArray);_x000D_
_x000D_
//run_x000D_
console.log(_x000D_
myArray.findIndexes((e) => e===5)_x000D_
)_x000D_
/*----Working with Array of complex items structure-*/_x000D_
_x000D_
let arr = [{name: 'Ahmed'}, {name: 'Rami'}, {name: 'Abdennour'}];_x000D_
_x000D_
arr= new EnhancedArray(...arr);_x000D_
_x000D_
_x000D_
console.log(_x000D_
arr.findIndexes((o) => o.name.startsWith('A'))_x000D_
)

string str = "2C F4 32 3C B9 DE";

I ran into this problem after a fresh install of Android Studio (in GNU/Linux). I also used the installation wizard for Android SDK, and the Build Tools 28.0.3 were installed, although Android Studio tried to use 28.0.2 instead.
But the problem was not the build tools version but the license. I had not accepted the Android SDK license (the wizard does not ask for it), and Android Studio refused to use the build tools; the error message just is wrong.
In order to solve the problem, I manually accepted the license. In a terminal, I launched $ANDROID_SDK/tools/bin/sdkmanager --licenses
and answered "Yes" for the SDK license. The other ones can be refused.
Use below code in spring rest side :
@PostMapping(value = Constant.API_INITIAL + "/uploadFile")
public UploadFileResponse uploadFile(@RequestParam("file") MultipartFile file,String jsonFileVo) {
FileUploadVo fileUploadVo = null;
try {
fileUploadVo = new ObjectMapper().readValue(jsonFileVo, FileUploadVo.class);
} catch (Exception e) {
e.printStackTrace();
}
This question has frequently been nominated as a canonical for people who try to use sh
and are surprised that it's not behaving the same as bash
. Here's a quick rundown of common misunderstandings and pitfalls.
First off, you should understand what to expect.
sh scriptname
, or run it with scriptname
and have #!/bin/sh
in the shebang line, you should expect POSIX sh
behavior.bash scriptname
, or run it with scriptname
and have #!/bin/bash
(or the local equivalent) in the shebang line, you should expect Bash behavior.Having a correct shebang and running the script by typing just the script name (possibly with a relative or full path) is generally the preferred solution. In addition to a correct shebang, this requires the script file to have execute permission (chmod a+x scriptname
).
So, how do they actually differ?
The Bash Reference manual has a section which attempts to enumerate the differences but some common sources of confusion include
[[
is not available in sh
(only [
which is more clunky and limited). See also Difference between single and double square brackets in Bashsh
does not have arrays.local
, source
, function
, shopt
, let
, declare
, and select
are not portable to sh
. (Some sh
implementations support e.g. local
.)for((i=0;i<=3;i++))
loop, +=
increment assignment, etc. The $'string\nwith\tC\aescapes'
feature is tentatively accepted for POSIX (meaning it works in Bash now, but will not yet be supported by sh
on systems which only adhere to the current POSIX specification, and likely will not for some time to come).<<<'here strings'
.*.{png,jpg}
and {0..12}
brace expansion.~

only in Bash (and more generally ~username
to the home directory of username
)./bin/sh

syntax which however should be replaced with POSIX arithmetic $((expression))
syntax. (Some legacy pre-POSIX sh
implementations may not support that, though.)type -a
, printf -v
, and the perennial echo -e
.$RANDOM
, $SECONDS
, $PIPESTATUS[@]
and $FUNCNAME
are Bash extensions.export variable=value
and [ "x" == "y" ]
which are not portable (export variable
should be separate from variable assignment, and portable string comparison in [ ... ]
uses a single equals sign).Remember, this is an abridged listing. Refer to the reference manual for the full scoop, and http://mywiki.wooledge.org/Bashism for many good workarounds; and/or try http://shellcheck.net/ which warns for many Bash-only features.
A common error is to have a #!/bin/bash
shebang line, but then nevertheless using sh scriptname
to actually run the script. This basically disables any Bash-only functionality, so you get syntax errors e.g. for trying to use arrays. (The shebang line is syntactically a comment, so it is simply ignored in this scenario.)
Unfortunately, Bash will not warn when you try to use these constructs when it is invoked as sh
. It doesn't completely disable all Bash-only functionality, either, so running Bash by invoking it as sh
is not a good way to check if your script is properly portable to ash
/dash
/POSIX sh
or variants like Heirloom sh

To invert a boolean Series, use ~s
:
In [7]: s = pd.Series([True, True, False, True])
In [8]: ~s
Out[8]:
0 False
1 False
2 True
3 False
dtype: bool
Using Python2.7, NumPy 1.8.0, Pandas 0.13.1:
In [119]: s = pd.Series([True, True, False, True]*10000)
In [10]: %timeit np.invert(s)
10000 loops, best of 3: 91.8 µs per loop
In [11]: %timeit ~s
10000 loops, best of 3: 73.5 µs per loop
In [12]: %timeit (-s)
10000 loops, best of 3: 73.5 µs per loop
As of Pandas 0.13.0, Series are no longer subclasses of numpy.ndarray
; they are now subclasses of pd.NDFrame
. This might have something to do with why np.invert(s)
is no longer as fast as ~s
or -s
.
Caveat: timeit
results may vary depending on many factors including hardware, compiler, OS, Python, NumPy and Pandas versions.

For your requirements it sounds like the bottom line will be to use Swing since it is slightly easier to get started with and not as tightly integrated to the native platform as SWT.
Swing usually is a safe bet.
If you really want to use itoa, you need to include the standard library header.
#include <stdlib.h>
I also believe that if you're on Windows (using MSVC), then itoa
is actually _itoa

Lets try to answer this question, with a good and simple scenario, with 3 MySQL
tables i.e. datetable, colortable and jointable.
first see values of table
datetable with primary key
assigned to column
dateid:
mysql> select * from datetable;
+--------+------------+
| dateid | datevalue |
+--------+------------+
| 101 | 2015-01-01 |
| 102 | 2015-05-01 |
| 103 | 2016-01-01 |
+--------+------------+
3 rows in set (0.00 sec)
now move to our second table
values colortable with primary key
assigned to column
colorid:
mysql> select * from colortable;
+---------+------------+
| colorid | colorvalue |
+---------+------------+
| 11 | blue |
| 12 | yellow |
+---------+------------+
2 rows in set (0.00 sec)
and our final third table
jointable have no primary keys
and values are:
mysql> select * from jointable;
+--------+---------+
| dateid | colorid |
+--------+---------+
| 101 | 11 |
| 102 | 12 |
| 101 | 12 |
+--------+---------+
3 rows in set (0.00 sec)
Now our condition is to find the dateid's, which have both color values blue and yellow.
So, our query is:
mysql> SELECT t1.dateid FROM jointable AS t1 INNER JOIN jointable t2
-> ON t1.dateid = t2.dateid
-> WHERE
-> (t1.colorid IN (SELECT colorid FROM colortable WHERE colorvalue = 'blue'))
-> AND
-> (t2.colorid IN (SELECT colorid FROM colortable WHERE colorvalue = 'yellow'));
+--------+
| dateid |
+--------+
| 101 |
+--------+
1 row in set (0.00 sec)
Hope, this would help many one.
Had the same problem and did two changes: (a) did not over-write existing data (not ideal if that is your intention but you can run a delete query beforehand), and (b) counted the columns and found that the csv had an empty column so it always pays to go back to your original work even though all 'seems' to look correct.
That's not how you send file on postman. What you did is sending a string which is the path of your image, nothing more.
What you should do is;
You're ready to go.
In your Django view,
from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
from rest_framework.decorators import parser_classes
@parser_classes((MultiPartParser, ))

def post(self, request, format=None):
thumbnail = request.FILES["file"]
info = json.loads(request.data['info'])
...
return HttpResponse()
In addition to the other suggestions - you can also wrap the flag in a control class and make a final instance of it in your parent class:
public class Test {
class Control {
public volatile boolean flag = false;
}
final Control control = new Control();
class T1 implements Runnable {
@Override
public void run() {
while ( !control.flag ) {
}
}
}
class T2 implements Runnable {
@Override
public void run() {
while ( !control.flag ) {
}
}
}
private void test() {
T1 main = new T1();
T2 help = new T2();
new Thread(main).start();
new Thread(help).start();
}
public static void main(String[] args) throws InterruptedException {
try {
Test test = new Test();
test.test();
} catch (Exception e) {
e.printStackTrace();
}
}
}

As the default configuration of Postgres, a user called postgres is made and the user postgres has full super admin access to entire PostgreSQL instance running on your OS.
sudo -u postgres psql
The above command gets you the psql command line interface in admin mode.

In pandas 16.2, I had to do pd.DataFrame.from_records(d)
to get this to work.
Important to note with elementFormDefault is that it applies to locally defined elements, typically named elements inside a complexType block, as opposed to global elements defined on the top-level of the schema. With elementFormDefault="qualified" you can address local elements in the schema from within the xml document using the schema's target namespace as the document's default namespace.
In practice, use elementFormDefault="qualified" to be able to declare elements in nested blocks, otherwise you'll have to declare all elements on the top level and refer to them in the schema in nested elements using the ref attribute, resulting in a much less compact schema.
This bit in the XML Schema Primer talks about it: http://www.w3.org/TR/xmlschema-0/#NS
Working fiddle:
$.ajax({
url: 'https://api.flightstats.com/flex/schedules/rest/v1/jsonp/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59',
dataType: 'JSONP',
jsonpCallback: 'callback',
type: 'GET',
success: function (data) {
console.log(data);
}
});
I had to manually set the callback to callback
, since that's all the remote service seems to support. I also changed the url to specify that I wanted jsonp.
Here is sample code (Ref from: Safe Area Layout Guide):
If you create your constraints in code use the safeAreaLayoutGuide property of UIView to get the relevant layout anchors. Let’s recreate the above Interface Builder example in code to see how it looks:
Assuming we have the green view as a property in our view controller:
private let greenView = UIView()
We might have a function to set up the views and constraints called from viewDidLoad:
private func setupView() {
greenView.translatesAutoresizingMaskIntoConstraints = false
greenView.backgroundColor = .green
view.addSubview(greenView)
}
Create the leading and trailing margin constraints as always using the layoutMarginsGuide of the root view:
let margins = view.layoutMarginsGuide
NSLayoutConstraint.activate([
greenView.leadingAnchor.constraint(equalTo: margins.leadingAnchor),
greenView.trailingAnchor.constraint(equalTo: margins.trailingAnchor)
])
Now, unless you are targeting iOS 11 and later, you will need to wrap the safe area layout guide constraints with #available and fall back to top and bottom layout guides for earlier iOS versions:
if #available(iOS 11, *) {
let guide = view.safeAreaLayoutGuide
NSLayoutConstraint.activate([
greenView.topAnchor.constraintEqualToSystemSpacingBelow(guide.topAnchor, multiplier: 1.0),
guide.bottomAnchor.constraintEqualToSystemSpacingBelow(greenView.bottomAnchor, multiplier: 1.0)
])
} else {
let standardSpacing: CGFloat = 8.0
NSLayoutConstraint.activate([
greenView.topAnchor.constraint(equalTo: topLayoutGuide.bottomAnchor, constant: standardSpacing),
bottomLayoutGuide.topAnchor.constraint(equalTo: greenView.bottomAnchor, constant: standardSpacing)
])
}
Result:
Here is Apple Developer Official Documentation for Safe Area Layout Guide
Safe Area is required to handle user interface design for iPhone-X. Here is basic guideline for How to design user interface for iPhone-X using Safe Area Layout
Use alternative HashMap implementation (Trove). Standard Java HashMap has >12x memory overhead. One can read details here.
The error tells you that there is an error but you don´t catch it. This is how you can catch it:
getAllPosts().then(response => {
console.log(response);
}).catch(e => {
console.log(e);
});
You can also just put a console.log(reponse)
at the beginning of your API callback function, there is definitely an error message from the Graph API in it.
More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch
Or with async/await:
//some async function
try {
let response = await getAllPosts();
} catch(e) {
console.log(e);
}
Box shadows can use commas to have multiple effects, just like with background images (in CSS3).
Here is my other simple answer to accept only numbers in the text box using Regular Expressions.

}
If I'm not mistaken, the default bean name of a bean declared with @Component is the name of its class its first letter in lower-case. This means that
@Component
public class SuggestionService {
declares a bean of type SuggestionService
, and of name suggestionService
. It's equivalent to
@Component("suggestionService")
public class SuggestionService {
or to
<bean id="suggestionService" .../>
You're redefining another bean of the same type, but with a different name, in the XML:
<bean id="SuggestionService" class="com.hp.it.km.search.web.suggestion.SuggestionService">
...
</bean>
So, either specify the name of the bean in the annotation to be SuggestionService
, or use the ID suggestionService
in the XML (don't forget to also modify the <ref>
element, or to remove it, since it isn't needed). In this case, the XML definition will override the annotation definition.
In my case I had to manually delete all the files in .m2\repository
folder and then open command prompt and run mvn -install
command in my project directory.
I managed to reproduce this error by doing the following.

Because the <
operator (and most others) are binary operators (they take two arguments), and (true true)
is not a valid boolean expression.
The Java language designers could have designed the language to allow syntax like the type you prefer, but (I'm guessing) they decided that it was not worth the more complex parsing rules.
There is a way to change the package name easily in Eclipse. Right click on your project, scroll down to Android Tools, and then click on Rename Application Package.
Here are some things that can fix this (in increasing order of difficulty):
Manually paste in
@IBOutlet weak var viewName: UIView!
// or
@IBAction func viewTapped(_ sender: Any) { }
and control drag to it. (Change type as needed.) Also see this.
Completely close Xcode and restart your project.
in fork(), either child or parent process will execute based on cpu selection.. But in vfork(), surely child will execute first. after child terminated, parent will execute.
What do you mean by impacts? Content will flow around a float. That's how they work.
If you want it to appear above your design, try setting:

You need to assign $first and $second
$first = $_POST['first'];
$second= $_POST['second'];
Also, As Travesty3 said, you need to do your arithmetic outside of the quotes:
echo $first + $second;

(Depending, you might need to: Set Path=C:\Program Files\7-Zip;%Path% )
I faced the same error while using pip on anaconda3 4.4.0 (python 3.6) on windows.
I fixed the problem by the following command:
easy_install pip==18.* ### installing the latest version pip
Or if lower version pip required, mention the same in the command.
Or you can try installing the lower version and then upgrading the same to latest version as follow:
easy_install pip==9.0.1
easy_install --upgrade pip
Using boolean algebra, it is easy to show that:
A xor B = (not A and B) or (A and not B)
A B | f = notA and B | g = A and notB | f or g | A xor B

0 0 | 0 | 0 | 0 | 0

In simpler words:
key=
parameter of sort
requires a key function (to be applied to be objects to be sorted) rather than a single key value and operator.itemgetter(1)
will give you: A function that grabs the first item from a list-like object. (More precisely those are callables, not functions, but that is a difference that can often be ignored.)
Use this style attribute for no word wrapping:
white-space: nowrap;
call below method on div or body tag onclick="show(event);" function show(event) {
var x = event.clientX;
var y = event.clientY;
var ele = document.getElementById("tt");
var width = ele.offsetWidth;
var height = ele.offsetHeight;
var half=(width/2);
if(x>half)
{
// alert('right click');
gallery.next();
}
else
{
// alert('left click');
gallery.prev();
}
}
According to the MediaPlayer
life cycle, which you can view in the Android API guide, I think that you have to call reset()
instead of stop()
, and after that prepare again the media player (use only one) to play the sound from the beginning. Take also into account that the sound may have finished. So I would also recommend to implement setOnCompletionListener()
to make sure that if you try to play again the sound it doesn't fail.
None of this worked for me in ios 7. Here is what I ended up doing. I put this in my custom cell class and call the method in my heightForCellAtIndexPath method.
My cell looks similar to the description cell when viewing an app in the app store.
First in the storyboard, set your label to 'attributedText', set the number of lines to 0 (which will resize the label automatically (ios 6+ only)) and set it to word wrap.
Then i just add up all the heights of the content of the cell in my custom Cell Class. In my case I have a Label at the top that always says "Description" (_descriptionHeadingLabel), a smaller label that is variable in size that contains the actual description (_descriptionLabel) a constraint from the top of the cell to the heading (_descriptionHeadingLabelTopConstraint). I also added 3 to space out the bottom a little bit (about the same amount apple places on the subtitle type cell.)
- (CGFloat)calculateHeight
{
CGFloat width = _descriptionLabel.frame.size.width;
NSAttributedString *attributedText = _descriptionLabel.attributedText;
CGRect rect = [attributedText boundingRectWithSize:(CGSize){width, CGFLOAT_MAX} options: NSStringDrawingUsesLineFragmentOrigin context:nil];
return rect.size.height + _descriptionHeadingLabel.frame.size.height + _descriptionHeadingLabelTopConstraint.constant + 3;
}
And in my Table View delegate:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
if (indexPath.row == 0) {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"descriptionCell"];
DescriptionCell *descriptionCell = (DescriptionCell *)cell;
NSString *text = [_event objectForKey:@"description"];
descriptionCell.descriptionLabel.text = text;
return [descriptionCell calculateHeight];
}
return 44.0f;
}
You can change the if statement to be a little 'smarter' and actually get the cell identifier from some sort of data source. In my case the cells are going to be hard coded since there will be fixed amount of them in a specific order.
Always use tax_query to get posts/products from a particular category or any other taxonomy. You can also get the products using ID/slug of particular taxonomy...
$the_query = new WP_Query( array(
'post_type' => 'product',
'tax_query' => array(
array (
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => 'accessories',
)
),
) );
while ( $the_query->have_posts() ) :
$the_query->the_post();
the_title(); echo "<br>";
endwhile;
wp_reset_postdata();
Basic example:
String fileName = "file.test";
BufferedOutputStream bs = null;
try {
FileOutputStream fs = new FileOutputStream(new File(fileName));
bs = new BufferedOutputStream(fs);
bs.write(byte_array);
bs.close();
bs = null;
} catch (Exception e) {
e.printStackTrace()
}
if (bs != null) try { bs.close(); } catch (Exception e) {}
I use it for lookup data. Load once from DB.

Personally I like to keep the label outside, like in your second example. That's why the FOR attribute is there. The reason being I'll often apply styles to the label, like a width, to get the form to look nice (shorthand below):
<style>
label {
width: 120px;
margin-right: 10px;
}
</style>
<label for="myinput">My Text</label>
<input type="text" id="myinput" /><br />
<label for="myinput2">My Text2</label>
<input type="text" id="myinput2" />
Makes it so I can avoid tables and all that junk in my forms.
There is a problem in that whilst:

It seems that there is no ISO/IEC 9075 way to recognize a pattern involving a left brace.
I've installed and use VB6 for legacy projects many times on Windows 7.
What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

I personally prefer the +
operator than append
:
for i in range(0, n):
list1 += [[i]]
But this is creating a new list every time, so might not be the best if performance is critical.
As an additional note, there is no need for the for loop because of R's vectorization.
This:
P <- 243.51
t <- 31 / 365
n <- 365
for (r in seq(0.15, 0.22, by = 0.01))
A <- P * ((1 + (r/ n))^ (n * t))
interest <- A - P
}
is equivalent to:
P <- 243.51
t <- 31 / 365
n <- 365
r <- seq(0.15, 0.22, by = 0.01)
A <- P * ((1 + (r/ n))^ (n * t))
interest <- A - P
Because r
is a vector, the expression above containing it is performed for all values of the vector.
Create a file named "config.js" in ./src folder with this content:
module.exports = global.config = {
i18n: {
welcome: {
en: "Welcome",
fa: "??? ?????"
}
// rest of your translation object
}
// other global config variables you wish
};
In your main file "index.js" put this line:
import './config';
Everywhere you need your object use this:
global.config.i18n.welcome.en
Kevin's answer works but It makes it hard to play with the data using that solution.
Best solution is don't start startActivityForResult()
on activity level.
in your case don't call getActivity().startActivityForResult(i, 1);
Instead, just use startActivityForResult()
and it will work perfectly fine! :)

With this API, QtCore.QString

I was looking for some information regarding reloads on pages retrieved with POST requests, such as after submitting a method="post"
form.
To reload the page keeping the POST data, use:
window.location.reload();
To reload the page discarding the POST data (perform a GET request), use:
window.location.href = window.location.href;
Hopefully this can help others looking for the same information.
<p>

They could probably be used interchangeably, but you shouldn't.
A canvas has 2 sizes, the dimension of the pixels in the canvas (it's backingstore or drawingBuffer) and the display size. The number of pixels is set using the the canvas attributes. In HTML
<canvas width="400" height="300"></canvas>
Or in JavaScript
someCanvasElement.width = 400;
someCanvasElement.height = 300;
Separate from that are the canvas's CSS style width and height
In CSS
canvas { /* or some other selector */
width: 500px;
height: 400px;
}
Or in JavaScript
canvas.style.width = "500px";
canvas.style.height = "400px";
The arguably best way to make a canvas 1x1 pixels is to ALWAYS USE CSS to choose the size then write a tiny bit of JavaScript to make the number of pixels match that size.

Because I didn't set the attributes the only thing that changed in each sample is the CSS (as far as the canvas is concerned)
Notes:
run this in Command Prompt windows (cmd.exe).
set PATH=C:\xampp\php;%PATH%
change it depending where you put the php 7 installation.
For commenting line use REM or :: though ::
might fail inside brackets
within delayed expansion lines starting with !<delimiter>
will be ignored so this can be used for comments:
@echo off
setlocal enableDelayedExpansion
echo delayed expansion activated
!;delayed expansion commented line
echo end of the demonstration
For comments at the end of line you can again use rem
and ::
combined with &
:
echo --- &:: comment (should not be the last line in the script)
echo --- &rem comment
As noting will be parsed after the exit
command you can use it to put comments at the end of the file:
@echo off
echo commands
exit /b
-------------------
commnts at the end
of the file
------------------
Expansion of not existing variables is replaced with nothing ,and as setting a variable with =
rather hard you can use this for inline comments:
@echo off
echo long command %= this is a comment =% with an inline comment
For multiline comments GOTO
(for outside brackets) and REM
with conditional execution (for inside brackets) can be used. More details here:
@echo off
echo starting script
goto :end_comments
comented line
one more commented line
:end_comments
echo continue with the script
(
echo demonstration off
rem/||(
lines with
comments
)
echo multiline comment inside
echo brackets
)
And the same technique beautified with macros:
@echo off
::GOTO comment macro
set "[:=goto :]%%"
::brackets comment macros
set "[=rem/||(" & set "]=)"
::testing
echo not commented 1
%[:%
multi
line
comment outside of brackets
%:]%
echo not commented 2
%[:%
second multi
line
comment outside of brackets
%:]%
::GOTO macro cannot be used inside for
for %%a in (first second) do (
echo first not commented line of the %%a execution
%[%
multi line
comment
%]%
echo second not commented line of the %%a execution
)
You use return false to prevent something from happening. So if you have a script running on submit then return false will prevent the submit from working.
To make the query run faster in big tables where not every line needs to be updated, you can also choose to only update rows that will be modified:
UPDATE dbo.xxx
SET Value = REPLACE(Value, '123', '')
WHERE ID <= 4
AND Value LIKE '%123%'
I have looked through many loggers, and I wasn't able to find a lightweight solution - so I decided to make a simple solution that is posted on github.
I hope this helps you out.

Note that -lm
may not always need to be specified even if you use some C math functions.
For example, the following simple program:
#include <stdio.h>
#include <math.h>
int main() {
printf("output: %f\n", sqrt(2.0));
return 0;
}
can be compiled and run successfully with the following command:
gcc test.c -o test
Tested on gcc 7.5.0 (on Ubuntu 16.04) and gcc 4.8.0 (on CentOS 7).
The post here gives some explanations:
The math functions you call are implemented by compiler built-in functions

Angularjs Dependency Injection framework is responsible for injecting the dependancies of you app module to your controllers. This is possible through its injector.
You need to first identify the ng-app and get the associated injector. The below query works to find your ng-app in the DOM and retrieve the injector.
angular.element('*[ng-app]').injector()
In chrome, however, you can point to target ng-app as shown below. and use the $0
hack and issue angular.element($0).injector()
Once you have the injector, get any dependency injected service as below
injector = angular.element($0).injector();
injector.get('$mdToast');
You can have multiple projects in one instance of Visual Studio. The point of a VS solution is to bring together all the projects you want to work with in one place, so you can't have multiple solutions in one instance. You'd have to open each solution separately.
I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):
sudo apt-get install python-setuptools python-dev build-essential
I'd avoid eval.
To solve this problem, you should know these things about JavaScript.
.
rather than square brackets []
, or vice versa.Your problem is a result of considering the dot manner of reference rather than the square bracket manner.
So, why not something like,
window["functionName"]();
That's assuming your function lives in the global space. If you've namespaced, then:
myNameSpace["functionName"]();
Avoid eval, and avoid passing a string in to setTimeout and setInterval. I write a lot of JS, and I NEVER need eval. "Needing" eval comes from not knowing the language deeply enough. You need to learn about scoping, context, and syntax. If you're ever stuck with an eval, just ask--you'll learn quickly.
.toString()
is available, or just add ""
to the end of the int
var x = 3,
toString = x.toString(),
toConcat = x + "";
Angular is simply JavaScript at the core.
There is one more use not covered here, and that is as part of an array type declaration as an argument to a function:
int someFunction(char arg[static 10])
{
...
}
In this context, this specifies that arguments passed to this function must be an array of type char
with at least 10 elements in it. For more info see my question here.
Or if you do not prefer to use LINQ you can do it the old-school way:
List<MyClass> list = new List<MyClass>();
foreach (MyClass element in list)
{
if (element.GetId() == "heres_where_you_put_what_you_are_looking_for")
{
break; // If you only want to find the first instance a break here would be best for your application
}
}
Adding to @mihai's answer:
If you are in Windows, then just concatenating __dirname' + '../public'
will result in wrong directory name (For example: c:\dev\app\module../public
).
Instead use path
, which will work irrespective of the OS:
var path = require ('path');
app.use(express.static(path.join(__dirname + '../public')));
path.join will normalize the path separator character and will return correct path value.
You can do git push --force
but be aware that you are rewriting history and anyone using the repo will have issue with this.
If you want to prevent this problem, don't use reset, but instead use git revert
If you really want to avoid touching this code, you can use Powermockito (PowerMock for Mockito).
With this, amongst many other things, you can mock the construction of new objects in a very easy way.
You can do it with CSS.
Put the buttons in the markup with the Next
button first, then the Prev
button afterwards.
Then use CSS to position them to appear the way you want.
I know i am probably the only one that will have this problem in this way. but if you deleted the mdf files in the C:/{user}/ directory, you will get this error too. restore it and you are golden
Do not connect() and end() inside the function. This will cause problems on repeated calls to the function. Make the connection only
var connection = mysql.createConnection({
host: 'localhost',
user: 'node',
password: 'node',
database: 'node_project'
})
connection.connect(function(err) {
if (err) throw err
});
once and reuse that connection.
Inside the function
function insertData(name,id) {
connection.query('INSERT INTO members (name, id) VALUES (?, ?)', [name,id], function(err,result) {
if(err) throw err
});
}
As my usecase involves dozens of columns, I expanded @jahroy's answer a bit. (also just realized @charles-clayton had the same idea.)
I pass the parameter I want to sort by, and the sort function is redefined with the desired index for the comparison to take place on.
var ID_COLUMN=0
var URL_COLUMN=1
findings.sort(compareByColumnIndex(URL_COLUMN))
function compareByColumnIndex(index) {
return function(a,b){
if (a[index] === b[index]) {
return 0;
}
else {
return (a[index] < b[index]) ? -1 : 1;
}
}
}
Unix cp
doesn't 'support both directories and files':
betelgeuse:tmp james$ cp source/ dest/
cp: source/ is a directory (not copied).
To make cp copy a directory, you have to manually tell cp that it's a directory, by using the '-r' flag.
There is some disconnect here though - cp -r
when passed a filename as the source will happily copy just the single file; copytree won't.
You just need to put [(ngModel)]
on your select element:
<select class="form-control col-lg-8" #corporation required [(ngModel)]="selectedValue">
For a .NET Core 2.0 console app, I did the following:
{ "myKey1" : "my test value 1", "myKey2" : "my test value 2", "foo" : "bar" }
Configure to copy the file to the output directory whenever the project is built (in VS -> Solution Explorer -> right-click file -> select 'Properties' -> Advanced -> Copy to Output Directory -> select 'Copy Always')
Install the following nuget package in my project:
Add the following to Program.cs (or wherever Main()
is located):
static void Main(string[] args)
{
var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json");
var configuration = builder.Build();
// rest of code...
}
Then read the values using either of the following ways:
string myKey1 = configuration["myKey1"];
Console.WriteLine(myKey1);
string foo = configuration.GetSection("foo").Value;
Console.WriteLine(foo);
May be this time stamp fit you better Code
Function LastInputTimeStamp() As Date
LastInputTimeStamp = Now()
End Function
and each time you input data in defined cell (in my example below it is cell C36) you'll get a new constant time stamp. As an example in Excel file may use this
=IF(C36>0,LastInputTimeStamp(),"")
document.forms['someform'].elements['someelement'].value
Found this post on a Google search, and it solved my issue thanks to @jwal reply, but I made one addition to his solution.
img.content.x700 {
width: auto !important; /*override the width below*/
width: 100%;
max-width: 678px;
float: left;
clear: both;
}
With the above I changed the max-width to the dimensions of the content container that my image is in. In this case it is: container width - padding - boarder = max width
This way my image won't break out of the containing div, and I can still float the image within the content div.
I've tested in IE 9, FireFox 18.0.2 and Chrome 25.0.1364.97, Safari iOS and seems to work.
Additional: I tested this on an image 1024px wide displayed at 678px (the max width), and an image 500px wide displayed at 500px (width of the image).
Please check the following file
%SystemRoot%\system32\drivers\etc\host
The line which bind the host name with ip is probably missing a line which bind them togather
127.0.0.1 localhost
If the given line is missing. Add the line in the file
Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.
If you are getting such error, the only reason could be you using a Distribution profile rather than a development profile in Xcode or a missing Entitlement property. If you are not using the Entitlements.plist, then the only possible error could be the app is getting packaged with a distribution profile. You could verify this confirming the build logs. To change this, go to Build Setting of the project and verify Code Signing Entity setting. For debugging to work, this setting should be a developer profile for the configuration that you are currently using.
https://developer.apple.com/library/ios/#qa/qa1682/_index.html
For instant results, delete all mobile provisioning profiles from xcode and install the developer profile that you intend to use.

Apart from the accepted answer, I'm suggesting another alternative.
Use QueryDSL, create a predicate and use the exists()
method that accepts a predicate and returns Boolean.
One advantage with QueryDSL is you can use the predicate for complicated where clauses.
Leap years and uneven months actually make this a non-trivial problem. I'm sure someone can come up with a more efficient way, but here's one option - approximate on the small side first and adjust up (untested):
public static void GetDifference(DateTime date1, DateTime date2, out int Years,
out int Months, out int Weeks, out int Days)
{
//assumes date2 is the bigger date for simplicity
//years
TimeSpan diff = date2 - date1;
Years = diff.Days / 366;
DateTime workingDate = date1.AddYears(Years);
while(workingDate.AddYears(1) <= date2)
{
workingDate = workingDate.AddYears(1);
Years++;
}
//months
diff = date2 - workingDate;
Months = diff.Days / 31;
workingDate = workingDate.AddMonths(Months);

I came here looking for same answer for node js. So here it is
const events = require('events');
const eventEmitter = new events.EventEmitter();
// Createing state to watch and trigger on change
let x = 10 // x is being watched for changes in do while loops below
do {
eventEmitter.emit('back to normal');
}
while (x !== 10);
do {
eventEmitter.emit('something changed');
}
while (x === 10);
What I am doing is setting some event emitters when values are changed and using do while loops to detect it.
I had the same problem. I was able to solve the problem from application side, under the following scenario:
JDK8, spring framework 4.2.4.RELEASE, apache tomcat 7.0.63, Oracle Database 11g Enterprise Edition 11.2.0.4.0
I used the database connection pooling apache tomcat-jdbc
:
You can take the following configuration parameters as a reference:
<Resource name="jdbc/exampleDB"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
validationQuery="SELECT 1 FROM DUAL"
validationInterval="30000"
timeBetweenEvictionRunsMillis="30000"
maxActive="100"
minIdle="10"
maxWait="10000"
initialSize="10"

This configuration was sufficient to fix the error. This works fine for me in the scenario mentioned above.

working workaround:
<div class="input-group">
<input type="text" class="form-control input-sm" value="test1" />
<span class="input-group-btn" style="width:0px;"></span>
<input type="text" class="form-control input-sm" value="test2" />
</div>
downside: no border-collapse between the two text-fields, but they keep next to each other
Update
thanks to Stalinko
This technique allows to glue more than 2 inputs.
Border-collapsing is achieved using "margin-left: -1px"
(-2px
for the 3rd input and so on)
<div class="input-group">
<input type="text" class="form-control input-sm" value="test1" />
<span class="input-group-btn" style="width:0px;"></span>
<input type="text" class="form-control input-sm" value="test2" style="margin-left:-1px" />

The best solution for this problem is just open your mysql configuration directive file my.ini present inside the folder C:\xampp\mysql\bin and change the information related to the ports, usually some programs occupy the port no. 3306 as a result of that it stops working, Now you follow two steps to make it working.
enter code here
Step-1. Search for ['client'], you can see some thing like this
[client]
# password = your_password
port = 3306
socket = "C:/xampp/mysql/mysql.sock"
Now in the port section remove 3306 and add port = 3306 > 3307 as shown below.
[client]
# password = your_password
port = 3306 > 3307
socket = "C:/xampp/mysql/mysql.sock"
Step -2. Similarly Search for ['mysqld'], you can see something like this
[mysqld]
port= 3306
socket = "C:/xampp/mysql/mysql.sock"
basedir = "C:/xampp/mysql"
tmpdir = "C:/xampp/tmp"
datadir = "C:/xampp/mysql/data"
pid_file = "mysql.pid"
# enable-named-pipe
key_buffer = 16M
max_allowed_packet = 1M
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
log_error = "mysql_error.log"
Now here change the port number 3306 to 3307 and add a line "innodb_force_recovery = 1" exactly as shown below.
[mysqld]
port= 3307
socket = "C:/xampp/mysql/mysql.sock"
basedir = "C:/xampp/mysql"
tmpdir = "C:/xampp/tmp"
datadir = "C:/xampp/mysql/data"
pid_file = "mysql.pid"
# enable-named-pipe
key_buffer = 16M
max_allowed_packet = 1M
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
log_error = "mysql_error.log"
innodb_force_recovery = 1
Thats it, restart you mysql service, it will work for sure.
For information purpose, _timestamp is now deprecated since 2.0.0-beta2.
Use date
type in your mapping.
A simple date mapping JSON from date
datatype doc:
{
"mappings": {
"my_type": {
"properties": {
"date": {
"type": "date"
}
}
}
}
}
You can also add a format
field in date
:
{
"mappings": {
"my_type": {
"properties": {
"date": {
"type": "date",
"format": "yyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
}
}
}
}
}
I needed the div to stop when it reach a certain object, so i did it like this:
var el = $('#followdeal');
var elpos_original = el.offset().top;
$(window).scroll(function(){
var elpos = el.offset().top;
var windowpos = $(window).scrollTop();
var finaldestination = windowpos;
var stophere = ( $('#filtering').offset().top ) - 170;
if(windowpos<elpos_original || windowpos>=stophere) {
finaldestination = elpos_original;
el.stop().animate({'top':10});
} else {
el.stop().animate({'top':finaldestination-elpos_original+10},500);
}
});
This should work fine:
{{ 'http://' ~ app.request.host }}
To add a filter - like 'trans' - in the same tag use
{{ ('http://' ~ app.request.host) | trans }}
As Adam Elsodaney points out, you can also use string interpolation, this does require double quoted strings:
{{ "http://#{app.request.host}" }}
It really depends on the filesystem used, and also some flags.
For example, ext3 can have many thousands of files; but after a couple of thousands, it used to be very slow. Mostly when listing a directory, but also when opening a single file. A few years ago, it gained the 'htree' option, that dramatically shortened the time needed to get an inode given a filename.
Personally, I use subdirectories to keep most levels under a thousand or so items. In your case, I'd create 256 directories, with the two last hex digits of the ID. Use the last and not the first digits, so you get the load balanced.
In short: No, your VOLUME
instruction is not correct.
Dockerfile's VOLUME
specify one or more volumes given container-side paths. But it does not allow the image author to specify a host path. On the host-side, the volumes are created with a very long ID-like name inside the Docker root. On my machine this is /var/lib/docker/volumes
.
Note: Because the autogenerated name is extremely long and makes no sense from a human's perspective, these volumes are often referred to as "unnamed" or "anonymous".
Your example that uses a '.' character will not even run on my machine, no matter if I make the dot the first or second argument. I get this error message:
docker: Error response from daemon: oci runtime error: container_linux.go:265: starting container process caused "process_linux.go:368: container init caused "open /dev/ptmx: no such file or directory"".
I know that what has been said to this point is probably not very valuable to someone trying to understand VOLUME
and -v
and it certainly does not provide a solution for what you try to accomplish. So, hopefully, the following examples will shed some more light on these issues.
Given this Dockerfile:
FROM openjdk:8u131-jdk-alpine
VOLUME vol1 vol2
(For the outcome of this minitutorial, it makes no difference if we specify vol1 vol2
or /vol1 /vol2
— this is because the default working directory within a Dockerfile is /
)
Build it:
docker build -t my-openjdk
Run:
docker run --rm -it my-openjdk
Inside the container, run ls
in the command line and you'll notice two directories exist; /vol1
and /vol2
.
Running the container also creates two directories, or "volumes", on the host-side.
While having the container running, execute docker volume ls
on the host machine and you'll see something like this (I have replaced the middle part of the name with three dots for brevity):
DRIVER VOLUME NAME
local c984...e4fc
local f670...49f0
Back in the container, execute touch /vol1/weird-ass-file
(creates a blank file at said location).
This file is now available on the host machine, in one of the unnamed volumes lol. It took me two tries because I first tried the first listed volume, but eventually I did find my file in the second listed volume, using this command on the host machine:
sudo ls /var/lib/docker/volumes/f670...49f0/_data
Similarly, you can try to delete this file on the host and it will be deleted in the container as well.
Note: The _data
folder is also referred to as a "mount point".
Exit out from the container and list the volumes on the host. They are gone. We used the --rm
flag when running the container and this option effectively wipes out not just the container on exit, but also the volumes.
Run a new container, but specify a volume using -v
:
docker run --rm -it -v /vol3 my-openjdk
This adds a third volume and the whole system ends up having three unnamed volumes. The command would have crashed had we specified only -v vol3
. The argument must be an absolute path inside the container. On the host-side, the new third volume is anonymous and resides together with the other two volumes in /var/lib/docker/volumes/
.
It was stated earlier that the Dockerfile
can not map to a host path which sort of pose a problem for us when trying to bring files in from the host to the container during runtime. A different -v
syntax solves this problem.
Imagine I have a subfolder in my project directory ./src
that I wish to sync to /src
inside the container. This command does the trick:
docker run -it -v $(pwd)/src:/src my-openjdk
Both sides of the :
character expects an absolute path. Left side being an absolute path on the host machine, right side being an absolute path inside the container. pwd
is a command that "print current/working directory". Putting the command in $()
takes the command within parenthesis, runs it in a subshell and yields back the absolute path to our project directory.
Putting it all together, assume we have ./src/Hello.java
in our project folder on the host machine with the following contents:
public class Hello {
public static void main(String... ignored) {
System.out.println("Hello, World!");
}
}
We build this Dockerfile:
FROM openjdk:8u131-jdk-alpine
WORKDIR /src
ENTRYPOINT javac Hello.java && java Hello
We run this command:
docker run -v $(pwd)/src:/src my-openjdk
This prints "Hello, World!".
The best part is that we're completely free to modify the .java file with a new message for another output on a second run - without having to rebuild the image =)
I am quite new to Docker, and the aforementioned "tutorial" reflects information I gathered from a 3-day command line hackathon. I am almost ashamed I haven't been able to provide links to clear English-like documentation backing up my statements, but I honestly think this is due to a lack of documentation and not personal effort. I do know the examples work as advertised using my current setup which is "Windows 10 -> Vagrant 2.0.0 -> Docker 17.09.0-ce".
The tutorial does not solve the problem "how do we specify the container's path in the Dockerfile and let the run command only specify the host path". There might be a way, I just haven't found it.
Finally, I have a gut feeling that specifying VOLUME
in the Dockerfile is not just uncommon, but it's probably a best practice to never use VOLUME
. For two reasons. The first reason we have already identified: We can not specify the host path - which is a good thing because Dockerfiles should be very agnostic to the specifics of a host machine. But the second reason is people might forget to use the --rm
option when running the container. One might remember to remove the container but forget to remove the volume. Plus, even with the best of human memory, it might be a daunting task to figure out which of all anonymous volumes are safe to remove.
If you want the list of all database sizes sorted, you can use :
SELECT *
FROM (SELECT table_schema AS `DB Name`,
ROUND(SUM(data_length + index_length) / 1024 / 1024, 1) AS `DB Size in MB`
FROM information_schema.tables
GROUP BY `DB Name`) AS tmp_table
ORDER BY `DB Size in MB` DESC;
Should you want what is exactly specified in the web page, just use:
document.querySelector('head base')['href']
With POST you can also do multipart mime encoding which means you can attach files as well. Also if you are using post variables across navigation of pages, the user will get a warning asking if they want to resubmit the post parameter. Typically they look the same in an HTTP request, but you should just stick to POST if you need to "POST" something TO a server and "GET" if you need to GET something FROM a server as that's the way they were intended.
The way I see it, the only place for a nested query would be in the WHERE clause, so e.g.
SELECT country.name, country.headofstate
FROM country
WHERE country.headofstate LIKE 'A%' AND
country.id in (SELECT country_id FROM city WHERE population > 100000)
Apart from that, I have to agree with Adrian on: why the heck should you use nested queries?
In general, bless
associates an object with a class.
package MyClass;
my $object = { };
bless $object, "MyClass";
Now when you invoke a method on $object
, Perl know which package to search for the method.
If the second argument is omitted, as in your example, the current package/class is used.
For the sake of clarity, your example might be written as follows:
sub new {
my $class = shift;
my $self = { };
bless $self, $class;
}
The answer, in a few words
In your example, itsProblem
is a local variable.
Your must use self
to set and get instance variables. You can set it in the __init__
method. Then your code would be:
class Example(object):
def __init__(self):
self.itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
But if you want a true class variable, then use the class name directly:
class Example(object):
itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
print (Example.itsProblem)
But be careful with this one, as theExample.itsProblem
is automatically set to be equal to Example.itsProblem
, but is not the same variable at all and can be changed independently.
Some explanations
In Python, variables can be created dynamically. Therefore, you can do the following:
class Example(object):
pass
Example.itsProblem = "problem"
e = Example()
e.itsSecondProblem = "problem"
print Example.itsProblem == e.itsSecondProblem
prints
True
Therefore, that's exactly what you do with the previous examples.
Indeed, in Python we use self
as this
, but it's a bit more than that. self
is the the first argument to any object method because the first argument is always the object reference. This is automatic, whether you call it self
or not.
Which means you can do:
class Example(object):
def __init__(self):
self.itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
or:
class Example(object):
def __init__(my_super_self):
my_super_self.itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
It's exactly the same. The first argument of ANY object method is the current object, we only call it self
as a convention. And you add just a variable to this object, the same way you would do it from outside.
Now, about the class variables.
When you do:
class Example(object):
itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
You'll notice we first set a class variable, then we access an object (instance) variable. We never set this object variable but it works, how is that possible?
Well, Python tries to get first the object variable, but if it can't find it, will give you the class variable. Warning: the class variable is shared among instances, and the object variable is not.
As a conclusion, never use class variables to set default values to object variables. Use __init__
for that.
Eventually, you will learn that Python classes are instances and therefore objects themselves, which gives new insight to understanding the above. Come back and read this again later, once you realize that.
You will get the un passed argument value as undefined. But in your case you have to pass at least null value in the first argument.
Or you have to change the method definition like
my_function = function(options, content) { action }
In the newer apache poi versions:
XSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop(BorderStyle.MEDIUM);
style.setBorderBottom(BorderStyle.MEDIUM);
style.setBorderLeft(BorderStyle.MEDIUM);
style.setBorderRight(BorderStyle.MEDIUM);
Simply don't put whole commands in variables. You'll get into a lot of trouble trying to recover quoted arguments.
Also:
#! /bin/bash
if [ $# -ne 2 ]
then
echo "Usage: $(basename $0) DIRECTORY BACKUP_DIRECTORY"
exit 1
fi
directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"
tar cv "$directory" | openssl des3 -salt | split -b 1024m - "$backup_file"
Use getJSON
$.getJSON(
'index.php?r=admin/post/ajax',
{"parentCatId":parentCatId},
function(data){
$.each(data, function(key, value){
console.log(key + ":" + value)
})
});

I had same problem on Fedora, and found that problem was selinux. to test that it is problem run command: sudo setenforce 0
Otherwise or change in file /etc/sysconfig/selinux

or add rules to selinux to allow http access
.grandparent{

In Python, you can use this code for automatic PostgreSQL table creation with column names:
import pandas, csv
from io import StringIO
from sqlalchemy import create_engine
def psql_insert_copy(table, conn, keys, data_iter):
dbapi_conn = conn.connection
with dbapi_conn.cursor() as cur:
s_buf = StringIO()
writer = csv.writer(s_buf)
writer.writerows(data_iter)
s_buf.seek(0)
columns = ', '.join('"{}"'.format(k) for k in keys)
if table.schema:
table_name = '{}.{}'.format(table.schema, table.name)
else:
table_name = table.name
sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(table_name, columns)
cur.copy_expert(sql=sql, file=s_buf)
engine = create_engine('postgresql://user:password@localhost:5432/my_db')
df = pandas.read_csv("my.csv")
df.to_sql('my_table', engine, schema='my_schema', method=psql_insert_copy)
It's also relatively fast, I can import more than 3.3 million rows in about 4 minutes.
What I would do is use the same trick often use for hovering on buttons. Prepare an image that has 2 parts: (1) a top half which is greyed out, meaning incomplete, and (2) a bottom half which is colored in, meaning completed. Use the same image 4 times to make up the 4 steps of the progress bar, and align top for incomplete steps, and align bottom for incomplete steps.
In order to take advantage of image alignment, you'd have to use the image as the background for 4 divs, rather than using the img element.
This is the CSS for background image alignment:
div.progress-incomplete {
background-position: top;
}
div.progress-finished {
background-position: bottom;
}
Here's a solution that moves the directives that need to be added dynamically, into the view and also adds some optional (basic) conditional-logic. This keeps the directive clean with no hard-coded logic.
The directive takes an array of objects, each object contains the name of the directive to be added and the value to pass to it (if any).
I was struggling to think of a use-case for a directive like this until I thought that it might be useful to add some conditional logic that only adds a directive based on some condition (though the answer below is still contrived). I added an optional if
property that should contain a bool value, expression or function (e.g. defined in your controller) that determines if the directive should be added or not.
I'm also using attrs.$attr.dynamicDirectives
to get the exact attribute declaration used to add the directive (e.g. data-dynamic-directive
, dynamic-directive
) without hard-coding string values to check for.

I'm using IBM Data Studio v 3.1.1.0 with an underlying DB2 for z/OS and the accepted answer didn't work for me. If you're using IBM Data Studio (v3.1.1.0) you can:
in your question you mentioned that your phpinfo was stating that apache was loading xdebug's configuration in /etc/php5/apache2/conf.d/xdebug.ini In many of the instructions online you may note that they ask you to put xdebug config in php.ini (and that is what I did) HOWEVER, if the configuration is set to /etc/php5/apache2/conf.d/xdebug.ini, then you should remove the [XDebug] configuration settings from /etc/php5/apache2/php.ini and put it in /etc/php5/apache2/conf.d/xdebug.ini INSTEAD. Once I removed from /etc/php5/apache2/php.ini and put in /etc/php5/apache2/conf.d/xdebug.ini instead, and restarted apache, it worked!!
Therefore, in your /etc/php5/apache2/conf.d/xdebug.ini, put the following:
[XDebug]
zend_extension="/usr/lib/php5/20121212+lfs/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_port="9000"
xdebug.profiler_enable=1
xdebug.profiler_output_dir="/home/paul/tmp"
xdebug.remote_host="localhost"
xdebug.remote_handler="dbgp";
xdebug.idekey="phpstorm_xdebug"
then remove this from the /etc/php5/apache2/php.ini if you put it there as well.
Then do:
sudo service apache2 restart
Then it should work!!!
To pull from the default branch, new repositories should use the command:
git pull origin main
Github changed naming convention of default branch from master to main in 2020. https://github.com/github/renaming
To fetch a branch that exists on remote, the simplest way is:
git fetch origin branchName
git checkout branchName
You can see if it already exists on remote with:
git branch -r
This will fetch the remote branch to your local and will automatically track the remote one.
I Would like to add how the pythonic key function works while sorting :
Decorate-Sort-Undecorate Design Pattern :
Python’s support for a key function when sorting is implemented using what is known as the decorate-sort-undecorate design pattern.
It proceeds in 3 steps:
Each element of the list is temporarily replaced with a “decorated” version that includes the result of the key function applied to the element.
The list is sorted based upon the natural order of the keys.
The decorated elements are replaced by the original elements.
Key parameter to specify a function to be called on each list element prior to making comparisons. docs
I observed that when I removed SessionMode from the ServiceContract attribute, the issue went away.
Example:
[ServiceContract(SessionMode=SessionMode.Required, CallbackContract=typeof(ICallbacks))]
public interface IStringReverser
{
[OperationContract]
string ReverseString(string value);
}
to...
[ServiceContract()]
public interface IStringReverser
{
[OperationContract]
string ReverseString(string value);
}
As you said, that string intern()
method will first find from the String pool, if it finds, then it will return the object that points to that, or will add a new String into the pool.
String s1 = "Hello";
String s2 = "Hello";
String s3 = "Hello".intern();
String s4 = new String("Hello");
System.out.println(s1 == s2);//true
System.out.println(s1 == s3);//true
System.out.println(s1 == s4.intern());//true
The s1
and s2
are two objects pointing to the String pool "Hello", and using "Hello".intern()
will find that s1
and s2
. So "s1 == s3"
returns true, as well as to the s3.intern()
.
I had the same problem when trying to use a token with Github.
The only syntax that has worked for me with Python 3 is:
import requests
myToken = '<token>'
myUrl = '<website>'
head = {'Authorization': 'token {}'.format(myToken)}
response = requests.get(myUrl, headers=head)
Just add:
import os
in the beginning, before:
from settings import PROJECT_ROOT
This will import the python's module os, which apparently is used later in the code of your module without being imported.
I usually shy away from queries from sys* type tables, vendors tend to change these between releases, major or otherwise. What I have always done is to issue the DROP FUNCTION <name>
statement and not worry about any SQL error that might come back. I consider that standard procedure in the DBA realm.
You can change the Authentication if u are running on Windows by reconfiguring the installation by running the msi. It will ask for changing the default authentication to legacy, then u can proceed with that option to change the authentication to the legacy one.
imo there's a better answer for this using Snippets
Create a snippet with a definition like this:
"name_of_your_snippet": {
"scope": "javascript,html",
"prefix": "name_of_your_snippet",
"body": "<${0:b}>$TM_SELECTED_TEXT</${0:b}>"
}
Then bind it to a key in keybindings.json E.g. like this:
{
"key": "alt+w",
"command": "editor.action.insertSnippet",
"args": { "name": "name_of_your_snippet" }
}
I think this should give you exactly the same result as htmltagwrap but without having to install an extension.
It will insert tags around selected text, defaults to <b>
tag & selects the tag so typing lets you change it.
If you want to use a different default tag just change the b
in the body
property of the snippet.
One option would be:
SET SERVEROUTPUT ON
EXEC DBMS_OUTPUT.PUT_LINE(your_fn_name(your_fn_arguments));
MobileSafari supports the orientationchange
event on the window
object. Unfortunately there doesn't seem to be a way to directly control the zoom via JavaScript. Perhaps you could dynamically write/change the meta
tag which controls the viewport — but I doubt that would work, it only affects the initial state of the page. Perhaps you could use this event to actually resize your content using CSS. Good luck!
A bit late to the party but might be valuable to someone with this error..
I just straight copied a bunch of files into an Xcode project, if you forget to add them to your projects Build Phases you will get the error "Undefined symbols for architecture i386". So add your implementation files to Compile Sources, and Xib files to Copy Bundle Resources.
The error was telling me that there was no link to my classes simply because they weren't included in the Compile Sources, quite obvious really but may save someone a headache.
I checked some of the methods for speed performance and find that there is no difference! The only difference is that using some methods you must carefully check dimension.
Timing:
|------------|----------------|-------------------|
| | shape (10000) | shape (1,10000) |
|------------|----------------|-------------------|
| np.concat | 0.18280 | 0.17960 |
|------------|----------------|-------------------|
| np.stack | 0.21501 | 0.16465 |
|------------|----------------|-------------------|
| np.vstack | 0.21501 | 0.17181 |
|------------|----------------|-------------------|
| np.array | 0.21656 | 0.16833 |
|------------|----------------|-------------------|
As you can see I tried 2 experiments - using np.random.rand(10000)
and np.random.rand(1, 10000)
And if we use 2d arrays than np.stack
and np.array
create additional dimension - result.shape is (1,10000,10000) and (10000,1,10000) so they need additional actions to avoid this.
Code:
from time import perf_counter
from tqdm import tqdm_notebook
import numpy as np
l = []
for i in tqdm_notebook(range(10000)):
new_np = np.random.rand(10000)
l.append(new_np)
start = perf_counter()
stack = np.stack(l, axis=0 )
print(f'np.stack: {perf_counter() - start:.5f}')
start = perf_counter()
vstack = np.vstack(l)
print(f'np.vstack: {perf_counter() - start:.5f}')
start = perf_counter()
wrap = np.array(l)
print(f'np.array: {perf_counter() - start:.5f}')
start = perf_counter()
l = [el.reshape(1,-1) for el in l]
conc = np.concatenate(l, axis=0 )
print(f'np.concatenate: {perf_counter() - start:.5f}')
You can make use of the SchUseStrongCrypto registry setting to require all .NET applications to use TLS 1.2 instead of 1.0 by default.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
If you use the Stopwatch class, you can use the .StartNew() method to reset the watch to 0. So you don't have to call .Reset() followed by .Start(). Might come in handy.
Callable is a type or class of "Build-in function or Method" with a method call
>>> type(callable)
<class 'builtin_function_or_method'>
>>>
Example: print is a callable object. With a build-in function __call__ When you invoke the print function, Python creates an object of type print and invokes its method __call__ passing the parameters if any.
>>> type(print)
<class 'builtin_function_or_method'>
>>> print.__call__(10)
10
>>> print(10)
10
>>>
Thank you. Regards, Maris
they are similar but not same
set.seed(0)
x<-matrix(rnorm(10),1)
# one can compute from the other
rank(x) == col(x)%*%diag(length(x))[order(x),]
order(x) == col(x)%*%diag(length(x))[rank(x),]
# rank can be used to sort
sort(x) == x%*%diag(length(x))[rank(x),]
In Python 3, this worked with me
import urllib
urllib.parse.quote(query)
I used skimage. You can create a collection and access elements the standard way, i.e. col[index]. This will give you the RGB values.
from skimage.io import imread_collection
#your path
col_dir = 'cats/*.jpg'
#creating a collection with the available images
col = imread_collection(col_dir)
In the terminal, I typed:
/usr/local/mysql/bin/mysql -u root -p
I was then prompted to enter the temporary password that was given to me upon completion of the installation.
This will loop through only once.
Item biggest = items.Aggregate((i1,i2) => i1.ID > i2.ID ? i1 : i2);
Thanks Nick - Here's the proof
class Program
{
static void Main(string[] args)
{
IEnumerable<Item> items1 = new List<Item>()
{
new Item(){ ClientID = 1, ID = 1},
new Item(){ ClientID = 2, ID = 2},
new Item(){ ClientID = 3, ID = 3},
new Item(){ ClientID = 4, ID = 4},
};
Item biggest1 = items1.Aggregate((i1, i2) => i1.ID > i2.ID ? i1 : i2);
Console.WriteLine(biggest1.ID);
Console.ReadKey();
}
}
public class Item
{
public int ClientID { get; set; }
public int ID { get; set; }
}
Rearrange the list and get the same result
I suggest to use a container for each img
p
like this:
<div class="image123">
<div style="float:left;margin-right:5px;">
<img src="/images/tv.gif" height="200" width="200" />
<p style="text-align:center;">This is image 1</p>
</div>
<div style="float:left;margin-right:5px;">
<img class="middle-img" src="/images/tv.gif/" height="200" width="200" />
<p style="text-align:center;">This is image 2</p>
</div>
<div style="float:left;margin-right:5px;">
<img src="/images/tv.gif/" height="200" width="200" />
<p style="text-align:center;">This is image 3</p>
</div>
</div>
Then apply float:left
to each container. I add and 5px
margin right
so there is a space between each image. Also alway close your elements. Maybe in html img
tag is not important to close but in XHTML is.
Also a friendly advice. Try to avoid inline styles as much as possible. Take a look here:
html
<div class="image123">
<div>
<img src="/images/tv.gif" />
<p>This is image 1</p>
</div>
<div>
<img class="middle-img" src="/images/tv.gif/" />
<p>This is image 2</p>
</div>
<div>
<img src="/images/tv.gif/" />
<p>This is image 3</p>
</div>
</div>
css
div{
float:left;
margin-right:5px;
}
div > img{
height:200px;
width:200px;
}
p{
text-align:center;
}
It's generally recommended that you use linked style sheets because:
All the other answers didn't work for me. (including cors package, or setting headers through middleware)
For socket.io 3^ this worked without any extra packages.
const express = require('express');
const app = express();
const server = require('http').createServer(app);
const io = require('socket.io')(server, {
cors: {
origin: "*",
methods: ["GET", "POST"]
}
});
Perhaps your character array needs to be constant. Since you're initializing your array with characters from a constant string, your array needs to be constant. Try this:
#define S "ABCD"
const char a[] = { S[0], S[1], S[2], S[3] };
You can also do it in easy way
def sum(numbers)
return 0 if numbers.length < 1
result = 0
numbers.each { |num| result += num }
result
end
The reason why Ng-Bind is better because,
When Your page is not Loaded or when your internet is slow or when your website loaded half, then you can see these type of issues (Check the Screen Shot with Read mark) will be triggered on Screen which is Completly weird. To avoid such we should use Ng-bind
If you are a guava user there is a handy Charsets
class:
String s = "Hello, world!";
byte[] b = s.getBytes(Charsets.US_ASCII);
Apart from not hard-coding arbitrary charset name in your source code it has a much bigger advantage: Charsets.US_ASCII
is of Charset
type (not String
) so you avoid checked UnsupportedEncodingException
thrown only from String.getBytes(String)
, but not from String.getBytes(Charset)
.
In Java 7 there is equivalent StandardCharsets
class.
JObject implements IDictionary, so you can use it that way. For ex,
var cycleJson = JObject.Parse(@"{""name"":""john""}");
//add surname
cycleJson["surname"] = "doe";
//add a complex object
cycleJson["complexObj"] = JObject.FromObject(new { id = 1, name = "test" });
So the final json will be
{
"name": "john",
"surname": "doe",
"complexObj": {
"id": 1,
"name": "test"
}
}
You can also use dynamic
keyword
dynamic cycleJson = JObject.Parse(@"{""name"":""john""}");
cycleJson.surname = "doe";
cycleJson.complexObj = JObject.FromObject(new { id = 1, name = "test" });
It usually represents some common service (protocol) that bluetooth device supports.
When creating your own rfcomm server (with listenUsingRfcommWithServiceRecord
), you should specify your own UUID so that the clients connecting to it could identify it;
it is one of the reasons why createRfcommSocketToServiceRecord
requires an UUID parameter.
Otherwise, some common services have the same UUID, just find one you need and use it.
See here
Collections use generics which support either reference types or wilcards. You can however use an Integer
wrapper
List<Integer> list = new ArrayList<>();
If you are using Anti-Virus, you can first check virus chest and restore from there. Otherwise, just go to your SDK Manager and install Android SDK Tools.
How about
# pattern is by finding a set of numbers in the start and capturing them
as.numeric(gsub("([0-9]+).*$", "\\1", years))
or
# pattern is to just remove _years_old
as.numeric(gsub(" years old", "", years))
or
# split by space, get the element in first index
as.numeric(sapply(strsplit(years, " "), "[[", 1))
This works for me on [{"id":"data"},{"id":"data"}]
function getObjects(obj, key, val)
{
var newObj = false;
$.each(obj, function()
{
var testObject = this;
$.each(testObject, function(k,v)
{
//alert(k);
if(val == v && k == key)
{
newObj = testObject;
}
});
});
return newObj;
}
You can put the graphic in a pseudo-element with its own dimensional context:

content: '';
z-index: -1;
width: 200px;

Browser support is good, but if you need to support IE8, use a single colon :before
. IE has no support for either syntax in versions prior to that.
