As Kevin Panko said, it's mostly because of library change. So in some cases a "clean" of the project (directory) followed by a build does the trick.
Since Oracle is the licensed product, there are issue in adding maven dependency directly. To add any version of the ojdbc.jar, below 2 steps could do.
/opt/apache-maven/bin/mvn install:install-file
-Dfile=<path-to-file>/ojdbc7.jar
-DgroupId=com.oracle
-DartifactId=ojdbc7
-Dversion=12.1.0.1.0
-Dpackaging=jar
This will add the dependency into local repository.
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc7</artifactId>
<version>12.1.0.1.0</version>
</dependency>
Currently, I know about the following three ways:
1. The @Value
annotation
@Value("${<property.name>}")
private static final <datatype> PROPERTY_NAME;
null
.
For instance,
when you try to set it in a preConstruct()
method or an init()
method.
This happens because the value injection happens after the class is fully constructed.
This is why it is better to use the 3'rd option.2. The @PropertySource
annotation
<pre>@PropertySource("classpath:application.properties")
//env is an Environment variable
env.getProperty(configKey);</pre>
PropertySouce
sets values from the property source file in an Environment
variable (in your class) when the class is loaded.
So you able to fetch easily afterword.
3. The @ConfigurationProperties
annotation.
It initializes an entity based on property data.
@ConfigurationProperties
identifies the property file to load.@Configuration
creates a bean based on configuration file variables.@ConfigurationProperties(prefix = "user") @Configuration("UserData") class user { //Property & their getter / setter } @Autowired private UserData userData; userData.getPropertyName();
The nodejs package tecfu/tty-table can be globally installed to do precisely this:
apt-get install nodejs
npm i -g tty-table
cat data.csv | tty-table
It can also handle streams.
For more info, see the docs for terminal usage here.
A simple function for testing if an input value is an array is the following:
function isArray(value)
{
return Object.prototype.toString.call(value) === '[object Array]';
}
This works cross browser, and with older browsers. This is pulled from T.J. Crowders' blog post
I have on several projects.
The biggest difference in my opinion
jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old
Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding
jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)
So what to choose?
That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?
I always end up using both, so I can use the best of both worlds.
Here are the links to both frameworks, if you decide to use them.
This issue has been fixed in the regular release of MVC4. Now you can do:
public string GetFindBooks(string author="", string title="", string isbn="", string somethingelse="", DateTime? date= null)
{
// ...
}
and everything will work out of the box.
You may want to double check the authorized_keys file permissions:
$ chmod 600 ~/.ssh/authorized_keys
Newer SSH server versions are very picky on this respect.
With this code i solved my problem.For back button paste these two line code.Hope this will help you.
Only paste this code on button click
super.onBackPressed();
Example:-
Button backButton = (Button)this.findViewById(R.id.back);
backButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
super.onBackPressed();
}
});
Assuming that onMove
is an event handler, it is likely that its context is something other than the instance of MyContainer
, i.e. this
points to something different.
You can manually bind the context of the function during the construction of the instance via Function.bind
:
class MyContainer extends Component {
constructor(props) {
super(props);
this.onMove = this.onMove.bind(this);
this.test = "this is a test";
}
onMove() {
console.log(this.test);
}
}
Also, test !== testVariable
.
Here's how you might implement a counter:
counter=0
while true; do
if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
echo "Files Present" | mailx -s "File Present" -r [email protected] [email protected]
exit 0
elif [[ "$counter" -gt 20 ]]; then
echo "Counter: $counter times reached; Exiting loop!"
exit 1
else
counter=$((counter+1))
echo "Counter: $counter time(s); Sleeping for another half an hour" | mailx -s "Time to Sleep Now" -r [email protected] [email protected]
sleep 1800
fi
done
Some Explanations:
counter=$((counter+1))
- this is how you can increment a counter. The $
for counter
is optional inside the double parentheses in this case.elif [[ "$counter" -gt 20 ]]; then
- this checks whether $counter
is not greater than 20
. If so, it outputs the appropriate message and breaks out of your while loop.How much a stack can grow?
You can use a VM option named ss
to adjust the maximum stack size. A VM option is usually passed using -X{option}. So you can use java -Xss1M
to set the maximum of stack size to 1M.
Each thread has at least one stack. Some Java Virtual Machines(JVM) put Java stack(Java method calls) and native stack(Native method calls in VM) into one stack, and perform stack unwinding using a Managed to Native Frame, known as M2NFrame. Some JVMs keep two stacks separately. The Xss
set the size of the Java Stack in most cases.
For many JVMs, they put different default values for stack size on different platforms.
Can we limit this growth?
When a method call occurs, a new stack frame will be created on the stack of that thread. The stack will contain local variables, parameters, return address, etc. In java, you can never put an object on stack, only object reference can be stored on stack. Since array is also an object in java, arrays are also not stored on stack. So, if you reduce the amount of your local primitive variables, parameters by grouping them into objects, you can reduce the space on stack. Actually, the fact that we cannot explicitly put objects on java stack affects the performance some time(cache miss).
Does stack has some default minimum value or default maximum value?
As I said before, different VMs are different, and may change over versions. See here.
how does garbage collection work on stack?
Garbage collections in Java is a hot topic. Garbage collection aims to collect unreachable objects in the heap. So that needs a definition of 'reachable.' Everything on the stack constitutes part of the root set references in GC. Everything that is reachable from every stack of every thread should be considered as live. There are some other root set references, like Thread objects and some class objects.
This is only a very vague use of stack on GC. Currently most JVMs are using a generational GC. This article gives brief introduction about Java GC. And recently I read a very good article talking about the GC on .net. The GC on oracle jvm is quite similar so I think that might also help you.
Everyone else has posted some perfectly reasonable answers. I took a different direction. Without using split, substring, or indexOf. Works great on i.e. and firefox. Probably works on Netscape too.
Just a loop and two ifs.
function getAfterDash(str) {
var dashed = false;
var result = "";
for (var i = 0, len = str.length; i < len; i++) {
if (dashed) {
result = result + str[i];
}
if (str[i] === '-') {
dashed = true;
}
}
return result;
};
console.log(getAfterDash("adfjkl-o812347"));
My solution is performant and handles edge cases.
The point of the above code was to procrastinate work, please don't actually use it.
You can dispatch the click event on a hidden file input like this:
<form action="#type your action here" method="POST" enctype="multipart/form-data">_x000D_
<div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" >Click to upload!</div>_x000D_
<!-- hide input[type=file]!-->_x000D_
<div style='height: 0px;width:0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>_x000D_
<input type="submit" value='submit' >_x000D_
</form>_x000D_
_x000D_
<script type="text/javascript">_x000D_
var btn = document.getElementById("yourBtn");_x000D_
var upfile = document.getElementById("upfile"); _x000D_
btn.addEventListener('click',function(){_x000D_

Example of AngularJS "global variables" using $rootScope
:
Controller 1 sets the global variable:
function MyCtrl1($scope, $rootScope) {
$rootScope.name = 'anonymous';
}
Controller 2 reads the global variable:
function MyCtrl2($scope, $rootScope) {
$scope.name2 = $rootScope.name;
}

Yes, it will recursively call your trigger unless you turn the recursive triggers setting off:
ALTER DATABASE db_name SET RECURSIVE_TRIGGERS OFF
MSDN has a good explanation of the behavior at http://msdn.microsoft.com/en-us/library/aa258254(SQL.80).aspx under the Recursive Triggers heading.
Try this
COALESCE(NULLIF(Address.COUNTRY,''), 'United States')
To correct @willsteel solution:

croppedBitmap = Bitmap.createBitmap(tempBitmap, start, 0, tempBitmap.getHeight(), tempBitmap.getHeight(), matrix, true);
} else {

croppedBitmap = Bitmap.createBitmap(tempBitmap, 0, start, tempBitmap.getWidth(), tempBitmap.getWidth(), matrix, true);
}
I adapted @mVchr's answer and inverted it to use for sticky ad positioning: if you need it absolutely positioned (scrolling) until the header junk is off screen but then need it to stay fixied/visible on screen after that:
$.fn.followTo = function (pos) {
var stickyAd = $(this),
theWindow = $(window);
$(window).scroll(function (e) {
if ($(window).scrollTop() > pos) {
stickyAd.css({'position': 'fixed','top': '0'});
} else {
stickyAd.css({'position': 'absolute','top': pos});
}
});
};
$('#sticky-ad').followTo(740);
CSS:
#sticky-ad {
float: left;
display: block;
position: absolute;
top: 740px;
left: -664px;
margin-left: 50%;
z-index: 9999;
}
Based on the hint and link provided in Simone Giannis answer, this is my hack to fix this.
I am testing on uri.getAuthority(), because UNC path will report an Authority. This is a bug - so I rely on the existence of a bug, which is evil, but it apears as if this will stay forever (since Java 7 solves the problem in java.nio.Paths).
Note: In my context I will receive absolute paths. I have tested this on Windows and OS X.
(Still looking for a better way to do it)
package com.christianfries.test;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.URL;
public class UNCPathTest {
public static void main(String[] args) throws MalformedURLException, URISyntaxException {
UNCPathTest upt = new UNCPathTest();
upt.testURL("file://server/dir/file.txt"); // Windows UNC Path
upt.testURL("file:///Z:/dir/file.txt"); // Windows drive letter path
upt.testURL("file:///dir/file.txt"); // Unix (absolute) path
}
private void testURL(String urlString) throws MalformedURLException, URISyntaxException {
URL url = new URL(urlString);
System.out.println("URL is: " + url.toString());
URI uri = url.toURI();
System.out.println("URI is: " + uri.toString());
if(uri.getAuthority() != null && uri.getAuthority().length() > 0) {
// Hack for UNC Path
uri = (new URL("file://" + urlString.substring("file:".length()))).toURI();
}
File file = new File(uri);
System.out.println("File is: " + file.toString());
String parent = file.getParent();
System.out.println("Parent is: " + parent);
System.out.println("____________________________________________________________");
}
}
Thanks to malat. Your comment helped me.
But I want to add my try-catch block, as I found the MExeption
method getReport()
that returns the whole error message and prints it to the matlab console.
Additionally I printed the filename as this compilation is part of a batch script that calls matlab.
try
some_code
...
catch message
display(['ERROR in file: ' message.stack.file])
display(['ERROR: ' getReport(message)])
end;
For a false model name passed to legacy code generation method, the output would look like:
ERROR in file: C:\..\..\..
ERROR: Undefined function or variable 'modelname'.
Error in sub-m-file (line 63)
legacy_code( 'slblock_generate', specs, modelname);
Error in m-file (line 11)
sub-m-file
Error in run (line 63)
evalin('caller', [script ';']);
Finally, to display the output at the windows command prompt window, just log the matlab console to a file with -logfile logfile.txt
(use additionally -wait
) and call the batch command type logfile.txt
If istream fails to insert, it will set the fail bit.
int i = 0;
std::cin >> i; // type a and press enter
if (std::cin.fail())
{
std::cout << "I failed, try again ..." << std::endl
std::cin.clear(); // reset the failed state
}
You can set this up in a do-while loop to get the correct type (int
in this case) propertly inserted.

It's not a good way.
When doing conversion from int to string, this should be used:

Float elements will be rendered at the line they are normally in the layout. To fix this, you have two choices:
Move the header and the p after the login box:
<div class='container'>
<div class='hero-unit'>
<div id='login-box' class='pull-right control-group'>
<div class='clearfix'>
<input type='text' placeholder='Username' />
</div>
<div class='clearfix'>
<input type='password' placeholder='Password' />
</div>
<button type='button' class='btn btn-primary'>Log in</button>
</div>
<h2>Welcome</h2>
<p>Please log in</p>
</div>
</div>
Or enclose the left block in a pull-left div, and add a clearfix at the bottom
<div class='container'>
<div class='hero-unit'>
<div class="pull-left">
<h2>Welcome</h2>
<p>Please log in</p>
</div>
<div id='login-box' class='pull-right control-group'>
<div class='clearfix'>
<input type='text' placeholder='Username' />
</div>
<div class='clearfix'>
<input type='password' placeholder='Password' />
</div>
<button type='button' class='btn btn-primary'>Log in</button>
</div>
<div class="clearfix"></div>
</div>
</div>
Use hasClass('in')
. It will return true if modal is in OPEN
state.
E.g:
if($('.modal').hasClass('in')){
//Do something here
}
I finally was able to run datepicker directive in angular js , here are pointers
include following JS in order
I added the following
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"> </script>
in html code
<body ng-app="myApp" ng-controller="myController">
// some other html code
<input type="text" ng-model="date" mydatepicker />
<br/>
{{ date }}
//some other html code
</body>
in the js , make sure you code for the directive first and after that add the code for controller , else it will cause issues.
date picker directive :
var app = angular.module('myApp',[]);
app.directive('mydatepicker', function () {
return {
restrict: 'A',
require: 'ngModel',
link: function (scope, element, attrs, ngModelCtrl) {
element.datepicker({
dateFormat: 'DD, d MM, yy',
onSelect: function (date) {
scope.date = date;
scope.$apply();
}
});
}
};
});
directive code referred from above answers.
After this directive , write the controller
app.controller('myController',function($scope){
//controller code
};
TRY THIS INSTEAD in angular js
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
along with jquery.js and jquery-ui.js
we can implement angular js datepicker as
<input type="date" ng-model="date" name="DOB">
This gives the built in datepicker and date is set in ng-model and can be used for further processing and validation.
Found this after lot of successful headbanging with previous approach. :)
I use something like this function I created...
Object.getKeys = function(obj, add) {
if(obj === undefined || obj === null) {
return undefined;
}
var keys = [];
if(add !== undefined) {
keys = jQuery.merge(keys, add);
}
for(key in obj) {
if(obj.hasOwnProperty(key)) {
keys.push(key);
}
}
return keys;
};
I think you could set obj to self or something better in the first test. It seems sometimes I'm checking if it's empty too so I did it that way. Also I don't think {} is Object.* or at least there's a problem finding the function getKeys on the Object that way. Maybe you're suppose to put prototype first, but that seems to cause a conflict with GreenSock etc.

int delta = 0Xff;
int gapIndex = target - nums[i] + delta;
if (vIndex[gapIndex] != 0) {
r[0] = vIndex[gapIndex];
r[1] = i + 1;
return r;
} else {
vIndex[nums[i] + delta] = i + 1;
}
}
return r;
}
You might be specifying a wrong version of java. java -version(in your terminal) to check the version of java you are using. Go to maven-compile-plugin for the latest maven compiler version Your plugin may appear like this if you are using java 6 and the latest version of maven compiler plugin is 3.1
<plugin>
<groupId>org.apache.maven.plugins</groupId>

A zone transfer is the only way to be sure you have all the subdomain records. If the DNS is correctly configured you should not normally be able to perform an external zone transfer.
The scans.io project has a database of DNS records that can be downloaded and searched for subdomains. This requires downloading the 87GB of DNS data, alternatively you can try the online search of the data at https://hackertarget.com/find-dns-host-records/
The border-radius property is supported in IE9+, Firefox 4+, Chrome, Safari 5+, and Opera, because it is CSS3 property. so, you could use css3pie
first check this demo in IE 8 and download it from here write your css rule like this
#myAwesomeElement {
border: 1px solid #999;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
behavior: url(path/to/pie_files/PIE.htc);
}
note: added behavior: url(path/to/pie_files/PIE.htc);
in the above rule. within url() you need to specify your PIE.htc file location
As .Net progresses, so does their ability to add new 32-bit configurations that trips everyone up it seems.

Put an image in with your app and load it on startup. Hold it until the app exits. The user wont be able to start a 2nd instance. (Of course the mutex solution is much cleaner)

worked for me, too.
{"params":["arg1", "arg2", ...]}

Unfortuantely, as div
elements can't be direct descendants of table
elements, the way I know to do this is to apply the CSS rules you want to each tr
element that you want to apply it to.
<table>
<tr><th>Test Table</th><tr>
<tr><td>123456789</td><tr>
<tr style="display: none; other-property: value;"><td>123456789</td><tr>
<tr style="display: none; other-property: value;"><td>123456789</td><tr>
<tr><td>123456789</td><tr>
<tr><td>123456789</td><tr>
</table>
If you have more than one CSS rule to apply to the rows in question, give the applicable rows a class
instead and offload the rules to external CSS.
<table>
<tr><th>Test Table</th><tr>
<tr><td>123456789</td><tr>
<tr class="something"><td>123456789</td><tr>
<tr class="something"><td>123456789</td><tr>
<tr><td>123456789</td><tr>
<tr><td>123456789</td><tr>

This is not possible in the requested way because there are numbers with two decimal places which can not be expressed exactly using IEEE floating point numbers (for example 1/10 = 0.1 can not be expressed as a Double
or Float
). The formatting should always happen as the last step before presenting the result to the user.
I guess you are asking because you want to deal with monetary values. There is no way to do this reliably with floating-point numbers, you shoud consider switching to fixed-point arithmetics. This probably means doing all calculations in "cents" instead of "dollars".
You probably need something like:
result.className = 'red';
In pure JavaScript you should use className
to deal with classes. jQuery has an abstraction called addClass
for it.
CSS 3 introduces rgba colour, and you can combine it with graphics for a backwards compatible solution.
You can't pass str
to your model fit()
method. as it mentioned here
The training input samples. Internally, it will be converted to dtype=np.float32 and if a sparse matrix is provided to a sparse csc_matrix.
Try transforming your data to float and give a try to LabelEncoder.
The easiest option is to just use the list() command. However, if you don't want to use it or it dose not work for some bazaar reason, you can always use this method.
word = 'foo'
splitWord = []
for letter in word:
splitWord.append(letter)
print(splitWord) #prints ['f', 'o', 'o']
Works on Windows
open command prompt (press Windows Key + R then type "cmd" without quotations in the appearing dialogue box and then press Enter Key).
then type the code sniff below :
then type following command
Then it will ask for Keystore password now. The default password is "android" type and enter or just hit enter "DONT TYPE ANY PASSWORD".
it looks like you are adding a blank item, and then databinding, which would empty the list; try inserting the blank item after databinding
Here is the solution I was looking for. If you would like to create List2 that contains the difference of the number elements in List1.
list1 = [12, 15, 22, 54, 21, 68, 9, 73, 81, 34, 45]
list2 = []
for i in range(1, len(list1)):
change = list1[i] - list1[i-1]
list2.append(change)
Note that while len(list1)
is 11 (elements), len(list2)
will only be 10 elements because we are starting our for loop from element with index 1 in list1 not from element with index 0 in list1
Simply add .. import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
imports: [ .. BrowserAnimationsModule
],
in app.module.ts file.
make sure you have installed .. npm install @angular/animations@latest --save
If you have an array that contains objects, you need to make a copy of that array without touching its internal pointer, and you need all the objects to be cloned (so that you're not modifying the originals when you make changes to the copied array), use this.
The trick to not touching the array's internal pointer is to make sure you're working with a copy of the array, and not the original array (or a reference to it), so using a function parameter will get the job done (thus, this is a function that takes in an array).
Note that you will still need to implement __clone() on your objects if you'd like their properties to also be cloned.
This function works for any type of array (including mixed type).
function array_clone($array) {
return array_map(function($element) {
return ((is_array($element))
? array_clone($element)
: ((is_object($element))
? clone $element
: $element
)
);
}, $array);
}
first Set id attribute of dropdownlist like i do here than use that id to get value in jquery or javascrip.
dropdownlist:
@Html.DropDownList("CompanyId", ViewBag.CompanyList as SelectList, "Select Company", new { @id="ddlCompany" })
jquery:
var id = jQuery("#ddlCompany option:selected").val();
While sourceSets
allows you to include entire directory structures, there's no way to exclude parts of it in Android Studio (as of version 1.2), as described here: Android Studio Exclude Class from build?
Until Android Studio gets updated to support include/exclude directives for Android sources, Symlinks work quite well. If you're using Windows, native tools such as junction
or mklink
can accomplish the equivalent of Un*x symlinks. CygWin can also create these with a little coersion. See: Git Symlinks in Windows and How to make symbolic link with cygwin in Windows 7
Remove the TO_DATE in the WHERE clause
TO_DATE (alarm_datetime,'DD.MM.YYYY HH24:MI:SS')
and change the code to
alarm_datetime
The error comes from to_date conversion of a date column.
Added Explanation: Oracle converts your alarm_datetime into a string using its nls depended date format. After this it calls to_date with your provided date mask. This throws the exception.
The easiest way to configure your system to use single ssh sessions by default with multiplexing.
This can be done by creating a folder for the sockets:
mkdir ~/.ssh/controlmasters
And then adding the following to your .ssh configuration:
Host *
ControlMaster auto
ControlPath ~/.ssh/controlmasters/%r@%h:%p.socket
ControlMaster auto
ControlPersist 10m
Now, you do not need to modify any of your code. This allows multiple calls to ssh and scp without creating multiple sessions, which is useful when there needs to be more interaction between your local and remote machines.
Thanks to @terminus's answer, http://www.cyberciti.biz/faq/linux-unix-osx-bsd-ssh-multiplexing-to-speed-up-ssh-connections/ and https://en.wikibooks.org/wiki/OpenSSH/Cookbook/Multiplexing.

If you really want to have a blocking (synchronous) delay
function (for whatsoever), why not do something like this:
<script type="text/javascript">
function delay(ms) {
var cur_d = new Date();
var cur_ticks = cur_d.getTime();
var ms_passed = 0;
while(ms_passed < ms) {
var d = new Date(); // Possible memory leak?
var ticks = d.getTime();
ms_passed = ticks - cur_ticks;
// d = null; // Prevent memory leak?
}
}
alert("2 sec delay")
delay(2000);
alert("done ... 500 ms delay")
delay(500);
alert("done");
</script>
std::iterator
with random_access_iterator_tag
.These base classes define all type definitions required by STL and do other work.To avoid code duplication iterator class should be a template class and be parametrized by "value type", "pointer type", "reference type" or all of them (depends on implementation). For example:
// iterator class is parametrized by pointer type
template <typename PointerType> class MyIterator {
// iterator class definition goes here
};
typedef MyIterator<int*> iterator_type;
typedef MyIterator<const int*> const_iterator_type;
Notice iterator_type
and const_iterator_type
type definitions: they are types for your non-const and const iterators.
See Also: standard library reference
EDIT: std::iterator
is deprecated since C++17. See a relating discussion here.
It's a very interesting question.
You can use both of them, there's not any strict rule about this subject, but using URI path variables has some advantages:
But if you use path variables, all of this services can cache your GET requests.
It gives the user more information about the structure of the data.
But if your data doesn't have any hierarchy relation you can still use Path variables, using comma or semi-colon:
/City/longitude,latitude
As a rule, use comma when the ordering of the parameters matter, use semi-colon when the ordering doesn't matter:
/IconGenerator/red;blue;green
Apart of those reasons, there are some cases when it's very common to use query string variables:
http:// www.google.com/search?q=rest
To sum up, there's not any strong reason to use one of this methods but whenever you can, use URI variables.
Using diffobj
package:
library(diffobj)
diffPrint(a1, a2)
diffObj(a1, a2)
As said before, you can use td { display: block; }
but this defeats the purpose of using a table.
You can use table { table-layout: fixed; }
but maybe you want it to behave differently for some colums.
So the best way to achieve what you want would be to wrap your text in a <div>
and apply your CSS to the <div>
(not to the <td>
) like this :
td {
border: 1px solid black;
}
td > div {
width: 50px;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
You can use https://github.com/musclesoft/jquery-connections. This allows you connect block elements in DOM.
Slightly more "Angular way" would be to use the straightforward limitTo
filter, as natively provided by Angular:
<ul class="phones">
<li ng-repeat="phone in phones | filter:query | orderBy:orderProp | limitTo:quantity">
{{phone.name}}
<p>{{phone.snippet}}</p>
</li>
</ul>
app.controller('PhoneListCtrl', function($scope, $http) {
$http.get('phones.json').then(
function(phones){
$scope.phones = phones.data;
}
);
$scope.orderProp = 'age';
$scope.quantity = 5;
}
);
You must have added new files in your commits which has not been pushed. Check the file and push that file again and the try pull / push it will work. This worked for me..
How wide is the text column?
With a GROUP BY there's not much you can do to avoid a data scan (at least an index scan).
I'd recommend:
If possible, changing the schema to remove duplication of text data. This way the count will happen on a narrow foreign key field in the 'many' table.
Alternatively, creating a generated column with a HASH of the text, then GROUP BY the hash column. Again, this is to decrease the workload (scan through a narrow column index)
Edit:
Your original question did not quite match your edit. I'm not sure if you're aware that the COUNT, when used with a GROUP BY, will return the count of items per group and not the count of items in the entire table.
I had a similar issue. In my case, I had to uninstall and then reinstall pip3:
sudo apt-get remove python3-pip
sudo apt-get install python3-pip
//1 year from today's date
echo date('d-m-Y', strtotime('+1 year'));
//1 year from from specific date
echo date('22-09-Y', strtotime('+1 year'));
hope this simpler bit of code helps someone in future :)
For iOS 9 users, this worked for me. just add this:
UINavigationBar.appearance().shadowImage = UIImage()
ArrayList<Matrices> list = new ArrayList<Matrices>();
list.add( new Matrices(1,1,10) );
list.add( new Matrices(1,2,20) );
string left = "411329_SOFT_MAC_GREEN";
string right= "SOFT_MAC_GREEN";
string[] l = left.Split('_');
string[] r = right.Split('_');
string[] distinctLeft = l.Distinct().ToArray();
string[] distinctRight = r.Distinct().ToArray();
var commonWord = l.Except(r, StringComparer.OrdinalIgnoreCase)
string result = String.Join("_",commonWord);
result = "411329"
Launch terminal and run open -n /Applications/Eclipse.app
for a new instance.
Lists are just a wrapper for a doubly-LinkedList in stl, thus offering feature you might expect from d-linklist namely O(1) insertion and deletion. While vectors are contagious data sequence which works like a dynamic array.P.S- easier to traverse.
if you need a init.py file in your folder make a copy of the folder and delete init.py in that one to run your tests it works for local projects. If you need to run test regularly see if you can move your init.py to a separate file.
Update: this literally answers the question asked, but I think KurzedMetal's answer is really what you want.
Assuming that:
master
master
in origin
.... you could do:
# Do a pull as usual, but don't commit the result:
git pull --no-commit
# Overwrite config/config.php with the version that was there before the merge
# and also stage that version:
git checkout HEAD config/config.php
# Create the commit:
git commit -F .git/MERGE_MSG
You could create an alias for that if you need to do it frequently. Note that if you have uncommitted changes to config/config.php
, this would throw them away.
Try:
select concat(first_name,last_name) as "Name" from test.student
or, better:
select concat(first_name," ",last_name) as "Name" from test.student
Generally speaking, people refer to an application's presentation layer as its front end, its persistence layer (database, usually) as the back end, and anything between as middle tier. This set of ideas is often referred to as 3-tier architecture. They let you separate your application into more easily comprehensible (and testable!) chunks; you can also reuse lower-tier code more easily in higher tiers.
Which code is part of which tier is somewhat subjective; graphic designers tend to think of everything that isn't presentation as the back end, database people think of everything in front of the database as the front end, and so on.
Not all applications need to be separated out this way, though. It's certainly more work to have 3 separate sub-projects than it is to just open index.php and get cracking; depending on (1) how long you expect to have to maintain the app (2) how complex you expect the app to get, you may want to forgo the complexity.
For a line-by-line delta measurement, try gnonom.
It is a command line utility, a bit like moreutils's ts, to prepend timestamp information to the standard output of another command. Useful for long-running processes where you'd like a historical record of what's taking so long.
Piping anything to gnomon will prepend a timestamp to each line, indicating how long that line was the last line in the buffer--that is, how long it took the next line to appear. By default, gnomon will display the seconds elapsed between each line, but that is configurable.
I just want to add what worked for me, I added height and width to both divs and used bootstrap to make it responsive

Correct answer is simply:
SELECT a.group_id
FROM a
LEFT JOIN b ON a.group_id=b.group_id and b.user_id = 4
where b.user_id is null
and a.keyword like '%keyword%'
Here we are checking user_id = 4
(your user id from the session). Since we have it in the join criteria, it will return null values for any row in table b that does not match the criteria - ie, any group that that user_id is NOT in.
From there, all we need to do is filter for the null values, and we have all the groups that your user is not in.

Sorry for being late, I have tried all above answers but none of them is giving me correct value, After doing the lot of R&D I have found a simple way that gives me exact value.
Declare this method in your class
private String hmacSha(String KEY, String VALUE, String SHA_TYPE) {
try {
SecretKeySpec signingKey = new SecretKeySpec(KEY.getBytes("UTF-8"), SHA_TYPE);
Mac mac = Mac.getInstance(SHA_TYPE);
mac.init(signingKey);
byte[] rawHmac = mac.doFinal(VALUE.getBytes("UTF-8"));
byte[] hexArray = {(byte)'0', (byte)'1', (byte)'2', (byte)'3', (byte)'4', (byte)'5', (byte)'6', (byte)'7', (byte)'8', (byte)'9', (byte)'a', (byte)'b', (byte)'c', (byte)'d', (byte)'e', (byte)'f'};
byte[] hexChars = new byte[rawHmac.length * 2];
for ( int j = 0; j < rawHmac.length; j++ ) {
int v = rawHmac[j] & 0xFF;
hexChars[j * 2] = hexArray[v >>> 4];
hexChars[j * 2 + 1] = hexArray[v & 0x0F];
}
return new String(hexChars);
}
catch (Exception ex) {
throw new RuntimeException(ex);
}
}
Use this like
Log.e("TAG", "onCreate: "+hmacSha("key","text","HmacSHA256"));

Yield : will make thread to wait for the currently executing thread and the thread which has called yield() will attaches itself at the end of the thread execution. The thread which call yield() will be in Blocked state till its turn.
Sleep : will cause the thread to sleep in sleep mode for span of time mentioned in arguments.
Join : t1 and t2 are two threads , t2.join() is called then t1 enters into wait state until t2 completes execution. Then t1 will into runnable state then our specialist JVM thread scheduler will pick t1 based on criteria's.

I use Windows Server 2012 for hosting for a long time and it just stop working after a more than years without any problem. My solution was to add public IP address of the server to list of relays and enabled Windows Integrated Authentication.
I just made two changes and I don't which help.
Go to IIS 6 Manager
Select properties of SMTP server
On tab Access, select Relays
Add your public IP address
Close the dialog and on the same tab click to Authentication button.
Add Integrated Windows Authentication
Maybe some step is not needed, but it works.
//BEWARE
//This works ONLY if the server returns 401 first
//The client DOES NOT send credentials on first request
//ONLY after a 401
client.Credentials = new NetworkCredential(userName, passWord); //doesnt work
//So use THIS instead to send credentials RIGHT AWAY
string credentials = Convert.ToBase64String(
Encoding.ASCII.GetBytes(userName + ":" + password));
client.Headers[HttpRequestHeader.Authorization] = string.Format(
"Basic {0}", credentials);

Much simpler solution:
pd.DataFrame(df2["teams"].to_list(), columns=['team1', 'team2'])
Yields,
team1 team2
-------------
0 SF NYG
1 SF NYG
2 SF NYG
3 SF NYG
4 SF NYG
5 SF NYG
6 SF NYG
7 SF NYG
If you wanted to split a column of delimited strings rather than lists, you could similarly do:
pd.DataFrame(df["teams"].str.split('<delim>', expand=True).values,
columns=['team1', 'team2'])
This is really just a syntax switch. OK, so we have this method call:
[NSPredicate predicateWithFormat:@"name contains[c] %@", searchText];
In Swift, constructors skip the "blahWith…" part and just use the class name as a function and then go straight to the arguments, so [NSPredicate predicateWithFormat: …]
would become NSPredicate(format: …)
. (For another example, [NSArray arrayWithObject: …]
would become NSArray(object: …)
. This is a regular pattern in Swift.)
So now we just need to pass the arguments to the constructor. In Objective-C, NSString literals look like @""
, but in Swift we just use quotation marks for strings. So that gives us:
let resultPredicate = NSPredicate(format: "name contains[c] %@", searchText)
And in fact that is exactly what we need here.
(Incidentally, you'll notice some of the other answers instead use a format string like "name contains[c] \(searchText)"
. That is not correct. That uses string interpolation, which is different from predicate formatting and will generally not work for this.)
I found this to work for me.
<script> document.write(unescape('%3Cscript src="' + window.location.protocol + "//" +
window.location.host + "/" + 'js/general.js?ver=2"%3E%3C/script%3E'))</script>

I have wondered the same thing. Basically it appears that the html spec has different content types for html and form data. Json only has a single content type.
According to the spec, a POST of json data should have the content-type:
application/json
Relevant portion of the HTML spec
6.7 Content types (MIME types)
...
Examples of content types include "text/html", "image/png", "image/gif", "video/mpeg", "text/css", and "audio/basic".17.13.4 Form content types
...
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows
Relevant portion of the JSON spec
- IANA Considerations
The MIME media type for JSON text is application/json.
I had the same question for macOS.

Some context on here: https://bugs.swift.org/browse/SR-1061
You're not adding a new instance of the class to the list. Try this:
lstemail.Add(new EmailData { FirstName="John", LastName="Smith", Location="Los Angeles" });`
List
is a generic class. When you specify a List<EmailData>
, the Add
method is expecting an object that's of type EmailData
. The example above, expressed in more verbose syntax, would be:
EmailData data = new EmailData();
data.FirstName="John";
data.LastName="Smith;
data.Location = "Los Angeles";
lstemail.Add(data);
You can also use static code block to instantiate the instance at class load and prevent the thread synchronization issues.
public class MySingleton {
private static final MySingleton instance;
static {
instance = new MySingleton();
}
private MySingleton() {
}
public static MySingleton getInstance() {
return instance;
}
}

Actually there is a way to make them bigger, checkboxes just like anything else (even an iframe like a facebook button).
Wrap them in a "zoomed" element:
.double {_x000D_
zoom: 2;_x000D_
transform: scale(2);_x000D_
-ms-transform: scale(2);_x000D_
-webkit-transform: scale(2);_x000D_
-o-transform: scale(2);_x000D_
-moz-transform: scale(2);_x000D_
transform-origin: 0 0;_x000D_
-ms-transform-origin: 0 0;_x000D_
-webkit-transform-origin: 0 0;_x000D_
-o-transform-origin: 0 0;_x000D_
-moz-transform-origin: 0 0;_x000D_
}
_x000D_
<div class="double">_x000D_
<input type="checkbox" name="hello" value="1">_x000D_
</div>
_x000D_
It might look a little bit "rescaled" but it works.
Of course you can make that div float:left and put your label besides it, float:left too.
It is better to use API Key in header, not in URL.
URLs are saved in browser's history if it is tried from browser. It is very rare scenario. But problem comes when the backend server logs all URLs. It might expose the API key.
In two ways, you can use API Key in header
Basic Authorization:
Example from stripe:
curl https://api.stripe.com/v1/charges -u sk_test_BQokikJOvBiI2HlWgH4olfQ2:
curl uses the -u flag to pass basic auth credentials (adding a colon after your API key will prevent it from asking you for a password).
Custom Header
curl -H "X-API-KEY: 6fa741de1bdd1d91830ba" https://api.mydomain.com/v1/users
In case you want jquery validate to auto pick validations on dynamically added items, you can simply remove and add validation on the whole form like below
//remove validations on entire form
$("#yourFormId")
.removeData("validator")
.removeData("unobtrusiveValidation");
//Simply add it again
$.validator
.unobtrusive
.parse("#yourFormId");
SELECT Col.Column_Name from
INFORMATION_SCHEMA.TABLE_CONSTRAINTS Tab,
INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE Col
WHERE
Col.Constraint_Name = Tab.Constraint_Name
AND Col.Table_Name = Tab.Table_Name
AND Constraint_Type = 'PRIMARY KEY'
AND Col.Table_Name = '<your table name>'
There are two easy ways:
In your cpanel Go to cpanel/ softaculous/ wordpress, under the current installation, you will see the websites you have installed with the wordpress. Click the "edit detail" of the particular website and you will see your SQL database username and password.
In your server Access your FTP and view the wp-config.php
.offset()
will return the offset position of an element as a simple object, eg:
var position = $(element).offset(); // position = { left: 42, top: 567 }
You can use this return value to position other elements at the same spot:
$(anotherElement).css(position)

Check out this great blog post by John Atten: ASP.NET Identity 2.0: Customizing Users and Roles
It has great step-by-step info on the whole process. Go read it : )
Here are some of the basics.
Extend the default ApplicationUser class by adding new properties (i.e.- Address, City, State, etc.):
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity>
GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
return userIdentity;
}
public string Address { get; set; }
public string City { get; set; }
public string State { get; set; }
// Use a sensible display name for views:
[Display(Name = "Postal Code")]
public string PostalCode { get; set; }
// Concatenate the address info for display in tables and such:
public string DisplayAddress
{
get
{
string dspAddress = string.IsNullOrWhiteSpace(this.Address) ? "" : this.Address;
string dspCity = string.IsNullOrWhiteSpace(this.City) ? "" : this.City;
string dspState = string.IsNullOrWhiteSpace(this.State) ? "" : this.State;
string dspPostalCode = string.IsNullOrWhiteSpace(this.PostalCode) ? "" : this.PostalCode;
return string.Format("{0} {1} {2} {3}", dspAddress, dspCity, dspState, dspPostalCode);
}
}
Then you add your new properties to your RegisterViewModel.
// Add the new address properties:
public string Address { get; set; }
public string City { get; set; }
public string State { get; set; }
Then update the Register View to include the new properties.
<div class="form-group">
@Html.LabelFor(m => m.Address, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextBoxFor(m => m.Address, new { @class = "form-control" })
</div>
</div>
Then update the Register() method on AccountController with the new properties.
// Add the Address properties:
user.Address = model.Address;
user.City = model.City;
user.State = model.State;
user.PostalCode = model.PostalCode;
More from Bill Phillip's article (go read it!) but i thought it was important to point out the following.
In ListView, there was some ambiguity about how to handle click events: Should the individual views handle those events, or should the ListView handle them through OnItemClickListener? In RecyclerView, though, the ViewHolder is in a clear position to act as a row-level controller object that handles those kinds of details.
We saw earlier that LayoutManager handled positioning views, and ItemAnimator handled animating them. ViewHolder is the last piece: it’s responsible for handling any events that occur on a specific item that RecyclerView displays.

One could use the Buffer
s that are provided as part of the java.nio
package to perform the conversion.
Here, the source byte[]
array has a of length 8, which is the size that corresponds with a long
value.
First, the byte[]
array is wrapped in a ByteBuffer
, and then the ByteBuffer.getLong
method is called to obtain the long
value:
ByteBuffer bb = ByteBuffer.wrap(new byte[] {0, 0, 0, 0, 0, 0, 0, 4});
long l = bb.getLong();
System.out.println(l);
Result
4
I'd like to thank dfa for pointing out the ByteBuffer.getLong
method in the comments.
Although it may not be applicable in this situation, the beauty of the Buffer
s come with looking at an array with multiple values.
For example, if we had a 8 byte array, and we wanted to view it as two int
values, we could wrap the byte[]
array in an ByteBuffer
, which is viewed as a IntBuffer
and obtain the values by IntBuffer.get
:
ByteBuffer bb = ByteBuffer.wrap(new byte[] {0, 0, 0, 1, 0, 0, 0, 4});
IntBuffer ib = bb.asIntBuffer();
int i0 = ib.get(0);
int i1 = ib.get(1);
System.out.println(i0);
System.out.println(i1);
Result:
1
4
This is pretty simple here is an example
Add your command code here like:
if (cmd === `!dm`) {
let dUser =
message.guild.member(message.mentions.users.first()) ||
message.guild.members.get(args[0]);
if (!dUser) return message.channel.send("Can't find user!");
if (!message.member.hasPermission('ADMINISTRATOR'))
return message.reply("You can't you that command!");
let dMessage = args.join(' ').slice(22);
if (dMessage.length < 1) return message.reply('You must supply a message!');
dUser.send(`${dUser} A moderator from WP Coding Club sent you: ${dMessage}`);
message.author.send(
`${message.author} You have sent your message to ${dUser}`
);
}
Assuming you have (or can easily make) a pid file for tracking the child's pid, you could then create a script that checks the modtime of the pid file and kills/respawns the process as needed. Then just put the script in crontab to run at approximately the period you need.
Let me know if you need more details. If that doesn't sound like it'd suit your needs, what about upstart?
You can do which python
and see if its pointing to the one in virtual env.

Finally, I solved it. Even though the solution is a bit lengthy, I think its the simplest. The solution is as follows:
- Install Visual Studio 2008
- Install the service Package 1 (SP1)
- Install SQL Server 2008 r2

Then, to change Java editor font: Java > Java Editor Text Font > EDIT
There it is.
You can use parents() to get all parents with the given selector.
Description: Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector.
But parent() will get just the first parent of the element.
Description: Get the parent of each element in the current set of matched elements, optionally filtered by a selector.
And there is .parentsUntil() which I think will be the best.
Description: Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector.
Given the following dataframe df
and the function complex_function
,
import pandas as pd
def complex_function(x, y=0):
if x > 5 and x > y:
return 1
else:
return 2
df = pd.DataFrame(data={'col1': [1, 4, 6, 2, 7], 'col2': [6, 7, 1, 2, 8]})
col1 col2
0 1 6
1 4 7
2 6 1
3 2 2
4 7 8
there are several solutions to use apply() on only one column. In the following I will explain them in detail.
The straightforward solution is the one from @Fabio Lamanna:
df['col1'] = df['col1'].apply(complex_function)
Output:
col1 col2
0 2 6
1 2 7
2 1 1
3 2 2
4 1 8
Only the first column is modified, the second column is unchanged. The solution is beautiful. It is just one line of code and it reads almost like english: "Take 'col1' and apply the function complex_function to it."
However, if you need data from another column, e.g. 'col2', it's not working. If you want to pass the values of 'col2' to variable y
of the complex_function
, you need something else.
Alternatively, you could use the whole dataframe as described in this or this SO post:
df['col1'] = df.apply(lambda x: complex_function(x['col1']), axis=1)
or if you prefer (like me) a solution without a lambda function:
def apply_complex_function(x): return complex_function(x['col1'])
df['col1'] = df.apply(apply_complex_function, axis=1)
There is a lot going on in this solution that needs to be explained. The apply() function works on pd.Series and pd.DataFrame. But you cannot use df['col1'] = df.apply(complex_function).loc[:, 'col1']
, because it would throw a ValueError
.
Hence, you need to give the information which column to use. To complicate things, the apply() function does only accept callables. To solve this, you need to define a (lambda) function with the column x['col1']
as argument; i.e. we wrap the column information in another function.
Unfortunately, the default value of the axis parameter is zero (axis=0
), which means it will try executing column-wise and not row-wise. This wasn't a problem in the first solution, because we gave apply() a pd.Series. But now the input is a dataframe and we must be explicit (axis=1
). (I marvel how often I forget this.)
Whether you prefer the version with the lambda function or without is subjective. In my opinion the line of code is complicated enough to read even without a lambda function thrown in. You only need the (lambda) function as a wrapper. It is just boiler code. A reader should not be bothered with it.
Now, you can modify this solution easily to take the second column into account:
def apply_complex_function(x): return complex_function(x['col1'], x['col2'])
df['col1'] = df.apply(apply_complex_function, axis=1)
Output:
col1 col2
0 2 6
1 2 7
2 1 1
3 2 2
4 2 8
At index 4 the value has changed from 1 to 2, because the first condition 7 > 5
is true but the second condition 7 > 8
is false.
Note that you only needed to change the first line of code (i.e. the function) and not the second line.
Never put the column information into your function.
def bad_idea(x):
return x['col1'] ** 2
By doing this, you make a general function dependent on a column name! This is a bad idea, because the next time you want to use this function, you cannot. Worse: Maybe you rename a column in a different dataframe just to make it work with your existing function. (Been there, done that. It is a slippery slope!)
Although the OP specifically asked for a solution with apply(), alternative solutions were suggested. For example, the answer of @George Petrov suggested to use map(), the answer of @Thibaut Dubernet proposed assign().
I fully agree that apply() is seldom the best solution, because apply() is not vectorized. It is an element-wise operation with expensive function calling and overhead from pd.Series.
One reason to use apply() is that you want to use an existing function and performance is not an issue. Or your function is so complex that no vectorized version exists.
Another reason to use apply() is in combination with groupby(). Please note that DataFrame.apply() and GroupBy.apply() are different functions.
So it does make sense to consider some alternatives:
map()
only works on pd.Series, but accepts dict and pd.Series as input. Using map() with a function is almost interchangeable with using apply(). It can be faster than apply(). See this SO post for more details. df['col1'] = df['col1'].map(complex_function)
applymap()
is almost identical for dataframes. It does not support pd.Series and it will always return a dataframe. However, it can be faster. The documentation states: "In the current implementation applymap calls func twice on the first column/row to decide whether it can take a fast or slow code path.". But if performance really counts you should seek an alternative route. df['col1'] = df.applymap(complex_function).loc[:, 'col1']
assign()
is not a feasible replacement for apply(). It has a similar behaviour in only the most basic use cases. It does not work with the complex_function
. You still need apply() as you can see in the example below. The main use case for assign() is method chaining, because it gives back the dataframe without changing the original dataframe. df['col1'] = df.assign(col1=df.col1.apply(complex_function))
I only mention it here because it was suggested by other answers, e.g. @durjoy. The list is not exhaustive:
.loc
. My example complex_function
could be refactored in this way.raw=True
parameter. Theoretically, this should improve the performance of apply() if you are just applying a NumPy reduction function, because the overhead of pd.Series is removed. Of course, your function has to accept an ndarray. You have to refactor your function to NumPy. By doing this, you will have a huge performance boost.It's Feb 2013, and I can now target XP in VS2012 by setting:
Project Properties -> General -> Platform Toolset to:
Visual Studio 2012 - Windows XP (v110_xp)
You will have to redistribute the msvcp110.dll libraries et al with your application, which are found here: "<Program Files>\Microsoft Visual Studio 11.0\VC\redist\x86\Microsoft.VC110.CRT\"
Update Aug 2015 with Visual Studio 2015
There seems to be quite a selection now. I was able to compile application in VS2015 using Visual Studio 2015 - Windows XP (v140_xp) setting. To make it actually run on Win XP I had to deploy (copy alongside application) msvcr100.dll for Release build and msvcr110.dll and msvcr100d.dll for Debug build (note there is a difference in numbers 100 and 110, also debug lib msvcr100d.dll may not be redistributable)
It seems that without return()
it's faster...

If you just want to change alignment of text just make a classes
.left {
text-align: left;
}
and span that class through the text
<span class='left'>aligned left</span>
To dynamically change the color of a text box goto properties, goto font/Color and set the following expression
=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)
Same way for tolerance
=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")
NumPy 1.8 introduced np.full()
, which is a more direct method than empty()
followed by fill()
for creating an array filled with a certain value:
>>> np.full((3, 5), 7)
array([[ 7., 7., 7., 7., 7.],
[ 7., 7., 7., 7., 7.],
[ 7., 7., 7., 7., 7.]])
>>> np.full((3, 5), 7, dtype=int)
array([[7, 7, 7, 7, 7],
[7, 7, 7, 7, 7],
[7, 7, 7, 7, 7]])
This is arguably the way of creating an array filled with certain values, because it explicitly describes what is being achieved (and it can in principle be very efficient since it performs a very specific task).
The best solution depends on how much code is incompatible. If there are a lot of places you need to support Python 2 and 3, six
is the compatibility module. six.PY2
and six.PY3
are two booleans if you want to check the version.
However, a better solution than using a lot of if
statements is to use six
compatibility functions if possible. Hypothetically, if Python 3000 has a new syntax for next
, someone could update six
so your old code would still work.
import six
#OK
if six.PY2:
x = it.next() # Python 2 syntax
else:
x = next(it) # Python 3 syntax
#Better
x = six.next(it)
Cheers
Yes there is something similar to pointers in PHP but may not match with what exactly happens in c or c++. Following is one of the example.
$a = "test";
$b = "a";
echo $a;
echo $b;
echo $$b;
//output
test
a
test
This illustrates similar concept of pointers in PHP.
"referencedColumnName" property is the name of the column in the table that you are making reference with the column you are anotating. Or in a short manner: it's the column referenced in the destination table. Imagine something like this: cars and persons. One person can have many cars but one car belongs only to one person (sorry, I don't like anyone else driving my car).
Table Person
name char(64) primary key
age intTable Car
car_registration char(32) primary key
car_brand (char 64)
car_model (char64)
owner_name char(64) foreign key references Person(name)
When you implement classes you will have something like
class Person{
...
}
class Car{
...
@ManyToOne
@JoinColumn([column]name="owner_name", referencedColumnName="name")
private Person owner;
}
EDIT: as @searchengine27 has commented, columnName
does not exist as a field in persistence section of Java7 docs. I can't remember where I took this property from, but I remember using it, that's why I'm leaving it in my example.
Wrap the text within the list item with a span (or some other element) and apply the bullet color to the list item and the text color to the span.
There are actually two place where where mac os x serves website by default:

If your date is not in format standar yyyy-mm-dd (2017-02-06) for example 20/06/2016. You can use this code
var parts ='01/07/2016'.val().split('/');
var d1 = Number(parts[2] + parts[1] + parts[0]);
parts ='20/06/2016'.val().split('/');
var d2 = Number(parts[2] + parts[1] + parts[0]);
return d1 > d2
This is the code I'm using:
private static byte[] xor(final byte[] input, final byte[] secret) {
final byte[] output = new byte[input.length];
if (secret.length == 0) {
throw new IllegalArgumentException("empty security key");
}
int spos = 0;
for (int pos = 0; pos < input.length; ++pos) {
output[pos] = (byte) (input[pos] ^ secret[spos]);
++spos;
if (spos >= secret.length) {
spos = 0;
}
}
return output;
}
It will give consistent behavior for add/remove operations. But while iterating you have to explicitly synchronized. Refer this link
PHP generates HTML. You may want:
echo "foo";
echo "<br />\n";
echo "bar";
With nginx you can send both tokens like this (even though it's against the standard):
Authorization: Basic basic-token,Bearer bearer-token
This works as long as the basic token is first - nginx successfully forwards it to the application server.
And then you need to make sure your application can properly extract the Bearer from the above string.
As Bhavik Shah says, you can do it in JAVA_OPTS, but the recommended way (as per catalina.sh) is to use CATALINA_OPTS:
# CATALINA_OPTS (Optional) Java runtime options used when the "start",
# "run" or "debug" command is executed.
# Include here and not in JAVA_OPTS all options, that should
# only be used by Tomcat itself, not by the stop process,
# the version command etc.
# Examples are heap size, GC logging, JMX ports etc.
# JAVA_OPTS (Optional) Java runtime options used when any command
# is executed.
# Include here and not in CATALINA_OPTS all options, that
# should be used by Tomcat and also by the stop process,
# the version command etc.
# Most options should go into CATALINA_OPTS.
Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:
All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.
This restriction accomplishes four functions, 1st and 3rd are important in this particular case:
And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.
One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.
There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:
If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.
Hope this will helps you to find the proper solution!
boto3 offers a resource model that makes tasks like iterating through objects easier. Unfortunately, StreamingBody doesn't provide readline
or readlines
.
s3 = boto3.resource('s3')
bucket = s3.Bucket('test-bucket')
# Iterates through all the objects, doing the pagination for you. Each obj
# is an ObjectSummary, so it doesn't contain the body. You'll need to call
# get to get the whole body.
for obj in bucket.objects.all():
key = obj.key
body = obj.get()['Body'].read()
A better way would be to use Stopwatch, instead of DateTime
differences.
Stopwatch Class - Microsoft Docs
Provides a set of methods and properties that you can use to accurately measure elapsed time.
Stopwatch stopwatch = Stopwatch.StartNew(); //creates and start the instance of Stopwatch
//your sample code
System.Threading.Thread.Sleep(500);
stopwatch.Stop();
Console.WriteLine(stopwatch.ElapsedMilliseconds);
The correct way to do this is:
typedef void (*callback_function)(void); // type for conciseness
callback_function disconnectFunc; // variable to store function pointer type
void D::setDisconnectFunc(callback_function pFunc)
{
disconnectFunc = pFunc; // store
}
void D::disconnected()
{
disconnectFunc(); // call
connected = false;
}
Try to use createChild() method of DOM or insertRow() and insertCell() method of table object in script tag.
$.ajax({
url: 'http://url.of.my.server/submit',
dataType: "jsonp",
jsonp: 'callback',
jsonpCallback: 'jsonp_callback'
});
jsonp is the querystring parameter name that is defined to be acceptable by the server while the jsonpCallback is the javascript function name to be executed at the client.
When you use such url:
url: 'http://url.of.my.server/submit?callback=?'
the question mark ? at the end instructs jQuery to generate a random function while the predfined behavior of the autogenerated function will just invoke the callback -the sucess function in this case- passing the json data as a parameter.
$.ajax({
url: 'http://url.of.my.server/submit?callback=?',
success: function (data, status) {
mySurvey.closePopup();
},
error: function (xOptions, textStatus) {
mySurvey.closePopup();
}
});
The same goes here if you are using $.getJSON with ? placeholder it will generate a random function while the predfined behavior of the autogenerated function will just invoke the callback:
$.getJSON('http://url.of.my.server/submit?callback=?',function(data){
//process data here
});

The cause of this for me was that the project was located on a network drive. I moved the project to the C: drive and everything ran without any delay.
If the project is located on a network drive, try moving it to your local C: drive and try it again.
The performance increase is much more than you would expect from just network speed. I guess VS is continually accessing the files when debugging an ASP.NET MVC application. I was using VS 2017, ASP.NET MVC debugging on IIS Express and this worked for me.
I hope this helps.
Using rcParams you can show grid very easily as follows
plt.rcParams['axes.facecolor'] = 'white'
plt.rcParams['axes.edgecolor'] = 'white'
plt.rcParams['axes.grid'] = True
plt.rcParams['grid.alpha'] = 1
plt.rcParams['grid.color'] = "#cccccc"
If grid is not showing even after changing these parameters then use
plt.grid(True)
before calling
plt.show()
I'm not sure if you can turn it off, but you can change the colors of it :)
myDiv::selection,
myDiv::-moz-selection,
myDiv::-webkit-selection {
background:#000;
color:#fff;
}
Then just match the colors to your "darky" design and see what happens :)
The answer can be actually quite more simple than ALL of the above, for example (in WPF):
public void YourTextBox_MouseEnter(object sender, MouseEventArgs e)
{
YourTextBox.Focus();
YourTextBox.SelectAll();
}
of course I can't know how you want to use this code, but the main part to look at here is: First call .Focus() and then call .SelectAll();
If an object's property may refer to some other object then you can test that for undefined before trying to use its properties:
if (thing && thing.foo)
alert(thing.foo.bar);
I could update my answer to better reflect your situation if you show some actual code, but possibly something like this:
function someFunc(parameterName) {
if (parameterName && parameterName.foo)
alert(parameterName.foo.bar);
}
As per answer by WarrenFaith, go to:
Settings -> Gradle -> Project-level settings
Change to Use customizable gradle wrapper.
Click OK and watch it build. If you still get an error at that stage, go back to:
Settings -> Gradle -> Project-level settings
Change it back to Use default gradle wrapper (recommended)
Click OK. That fixed it for me.
@jim's answer is correct -- fuser
is what you want.
Additionally (or alternately), you can use lsof
to get more information including the username, in case you need permission (without having to run an additional command) to kill the process. (THough of course, if killing the process is what you want, fuser
can do that with its -k
option. You can have fuser
use other signals with the -s
option -- check the man page for details.)
For example, with a tail -F /etc/passwd
running in one window:
ghoti@pc:~$ lsof | grep passwd
tail 12470 ghoti 3r REG 251,0 2037 51515911 /etc/passwd
Note that you can also use lsof
to find out what processes are using particular sockets. An excellent tool to have in your arsenal.
Example 1:
RestTemplate restTemplate = new RestTemplate();
// Add the Jackson message converter
restTemplate.getMessageConverters()
.add(new MappingJackson2HttpMessageConverter());
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Basic XXXXXXXXXXXXXXXX=");
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
restTemplate.getInterceptors()
.add(new BasicAuthorizationInterceptor(USERID, PWORD));
String requestJson = getRequetJson(Code, emailAddr, firstName, lastName);
response = restTemplate.postForObject(URL, requestJson, MYObject.class);
Example 2:
RestTemplate restTemplate = new RestTemplate();
String requestJson = getRequetJson(code, emil, name, lastName);
HttpHeaders headers = new HttpHeaders();
String userPass = USERID + ":" + PWORD;
String authHeader =
"Basic " + Base64.getEncoder().encodeToString(userPass.getBytes());
headers.set(HttpHeaders.AUTHORIZATION, authHeader);
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
HttpEntity<String> request = new HttpEntity<String>(requestJson, headers);
ResponseEntity<MyObject> responseEntity;
responseEntity =
this.restTemplate.exchange(URI, HttpMethod.POST, request, Object.class);
responseEntity.getBody()
The getRequestJson
method creates a JSON Object:
private String getRequetJson(String Code, String emailAddr, String name) {
ObjectMapper mapper = new ObjectMapper();
JsonNode rootNode = mapper.createObjectNode();
((ObjectNode) rootNode).put("code", Code);
((ObjectNode) rootNode).put("email", emailAdd);
((ObjectNode) rootNode).put("firstName", name);
String jsonString = null;
try {
jsonString = mapper.writerWithDefaultPrettyPrinter()
.writeValueAsString(rootNode);
}
catch (JsonProcessingException e) {
e.printStackTrace();
}
return jsonString;
}
If it's not important to use a RelativeLayout, you could use a LinearLayout, and do this:
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
Doing this allows you to avoid the addRule method you've tried. You can simply use addView() to add new TextViews.
Complete code:
String[] textArray = {"One", "Two", "Three", "Four"};
LinearLayout linearLayout = new LinearLayout(this);
setContentView(linearLayout);
linearLayout.setOrientation(LinearLayout.VERTICAL);
for( int i = 0; i < textArray.length; i++ )
{
TextView textView = new TextView(this);
textView.setText(textArray[i]);
linearLayout.addView(textView);
}
var bmp = new Bitmap(@"path\picture.bmp");
using( Graphics g = Graphics.FromImage( bmp ) )
{
g.DrawString( ... );
}
picturebox1.Image = bmp;
Try:
"${str:$((${#str}-1)):1}"
For e.g.:
someone@mypc:~$ str="A random string*"; echo "$str"
A random string*
someone@mypc:~$ echo "${str:$((${#str}-1)):1}"
*
someone@mypc:~$ echo "${str:$((${#str}-2)):1}"
g
unset
is the command you're looking for.
unset GNUPLOT_DRIVER_DIR
I use this in my code in a custom class. Comes in handy for sending out emails like [email protected] "no-reply@" + BaseSiteUrl Works fine on any site.
// get a sites base urll ex: example.com
public static string BaseSiteUrl
{
get
{
HttpContext context = HttpContext.Current;
string baseUrl = context.Request.Url.Authority + context.Request.ApplicationPath.TrimEnd('/');
return baseUrl;
}
}
If you want to use it in codebehind get rid of context.
Is there a prize for being lazy and using the transpose function of NumPy arrays? ;)
import numpy as np
a = np.array([(1,2,3), (4,5,6)])
b = a.transpose()
First of all, you need to check that the IIS is installed in your machine, for that you can go to:
Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'
If not, check it, and Press Accept to install it.
Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).
Edit:
You should have something like this:
Batch files don't work that way. They don't just "type" everything - they run system commands, in this case ftp
, wait for them to return, and run the next command... so in this case, the interpreter is simply waiting for ftp
to exit.
If you must use the ftp
command, then prepare a script file (for example, commands.txt
and run ftp -s:commands.txt
.
But using cURL, or a PHP/Perl/Python/whatever script may be a better idea.
For other people who might run into this, don't forget to check ~/.mavenrc for M2_HOME or JAVA_HOME settings.
The best way to use is white-space: nowrap;
This will align the text to one line.
I don't know if it's possible to run it just like that.
I usually first copy it with scp and then log in to run it.
scp foo.sh user@host:~
ssh user@host
./foo.sh
The performance tests here are not correct:
e.g.
timeit.Timer('for i in xrange(100): app(i)', 's = [] ; app = s.append').timeit()

Answer updated for 2020:
Both <object>
and <embed>
are included in the WHAT-WG HTML Living Standard (Sept 2020).
<object>
The object element can represent an external resource, which, depending on the type of the resource, will either be treated as an image, as a child browsing context, or as an external resource to be processed by a plugin.
<embed>
The embed element provides an integration point for an external (typically non-HTML) application or interactive content.
Are there advantages/disadvantages to using one tag vs. the other?
The opinion of Mozilla Developer Network (MDN) appears (albeit fairly subtly) to very marginally favour <object>
over <embed>
but overwhelmingly, MDN, wants to recommend that wherever you can, you avoid embedding external content entirely.
[...] you are unlikely to use these elements very much — Applets haven't been used for years, Flash is no longer very popular, due to a number of reasons (see The case against plugins, below), PDFs tend to be better linked to than embedded, and other content such as images and video have much better, easier elements to handle those. Plugins and these embedding methods are really a legacy technology, and we are mainly mentioning them in case you come across them in certain circumstances like intranets, or enterprise projects.
Once upon a time, plugins were indispensable on the Web. Remember the days when you had to install Adobe Flash Player just to watch a movie online? And then you constantly got annoying alerts about updating Flash Player and your Java Runtime Environment. Web technologies have since grown much more robust, and those days are over. For virtually all applications, it's time to stop delivering content that depends on plugins and start taking advantage of Web technologies instead.
To complement Felix Kling's answer, I was studying a codebase that used to have the following code:
if (is_array($start_vars)) {
foreach ($start_vars as $var) {
session_register($var);
}
} else if (!(empty($start_vars))) {
session_register($start_vars);
}
In order to not use session_register they made the following adjustments:
if (is_array($start_vars)) {
foreach ($start_vars as $var) {
$_SESSION[$var] = $GLOBALS[$var];
}
} else if (!(empty($start_vars))) {
$_SESSION[$start_vars] = $GLOBALS[$start_vars];
}
$(document).ready(function () {
toggleFields(); // call this first so we start out with the correct visibility depending on the selected form values
// this will call our toggleFields function every time the selection value of our other field changes
$("#dbType").change(function () {
toggleFields();
});
});
// this toggles the visibility of other server
function toggleFields() {
if ($("#dbType").val() === "other")
$("#otherServer").show();
else
$("#otherServer").hide();
}
HTML:
<p>Choose type</p>
<p>Server:
<select id="dbType" name="dbType">
<option>Choose Database Type</option>
<option value="oracle">Oracle</option>
<option value="mssql">MS SQL</option>
<option value="mysql">MySQL</option>
<option value="other">Other</option>

Without a look at your exact JSON output, it's hard to give you some working code. This tutorial is very useful, but you could use something along the lines of:
JSONObject jsonObj = new JSONObject("yourJsonString");
Then you can retrieve from this json object using:
String value = jsonObj.getString("yourKey");
I have a list of positions of array to retrieve ,This worked for me.
public void create_list_to_add_group(ArrayList<Integer> arrayList_loc) {
//In my case arraylist_loc is the list of positions to retrive from
// contact_names
//arraylist and phone_number arraylist
ArrayList<String> group_members_list = new ArrayList<>();
ArrayList<String> group_members_phone_list = new ArrayList<>();
int size = arrayList_loc.size();
for (int i = 0; i < size; i++) {
try {
int loc = arrayList_loc.get(i);
group_members_list.add(contact_names_list.get(loc));
group_members_phone_list.add(phone_num_list.get(loc));
} catch (Exception e) {
e.printStackTrace();
}
}
Log.e("Group memnbers list", " " + group_members_list);
Log.e("Group memnbers num list", " " + group_members_phone_list);
}
If you want a method in which you know the algorithm, or the functions mentioned in the previous answer aren't available: convert the date to Julian Day number (which is a way of counting days from January 1st, 4713 B.C), then subtract five, then convert back to calendar date (year, month, day). Sources of the algorithms for the two conversions is section 9 of http://www.hermetic.ch/cal_stud/jdn.htm or http://en.wikipedia.org/wiki/Julian_day
First select the text
To convert lowercase to uppercase, press Ctrl+Shift+U
To convert uppercase to lowercase, press Ctrl+U
public String stripNonValidXMLCharacters(String in) {
StringBuffer out = new StringBuffer(); // Used to hold the output.
char current; // Used to reference the current character.
if (in == null || ("".equals(in))) return ""; // vacancy test.
for (int i = 0; i < in.length(); i++) {
current = in.charAt(i); // NOTE: No IndexOutOfBoundsException caught here; it should not happen.
if ((current == 0x9) ||
(current == 0xA) ||
(current == 0xD) ||
((current >= 0x20) && (current <= 0xD7FF)) ||
((current >= 0xE000) && (current <= 0xFFFD)) ||
((current >= 0x10000) && (current <= 0x10FFFF)))
out.append(current);
}
return out.toString();
}
Please see my answer here. As dreamwerx.myopenid.com points out, it is possible to do this with SimpleXML, but the DOM extension would be the better and more flexible way. Additionally there is a third way: using XMLWriter. It's much more simple to use than the DOM and therefore it's my preferred way of writing XML documents from scratch.
$w=new XMLWriter();
$w->openMemory();
$w->startDocument('1.0','UTF-8');
$w->startElement("root");
$w->writeAttribute("ah", "OK");
$w->text('Wow, it works!');
$w->endElement();
echo htmlentities($w->outputMemory(true));
By the way: DOM stands for Document Object Model; this is the standardized API into XML documents.
a possible solution could be
create a batch file
there do a loop on lib directory for all files inside it and set each file unside lib on classpath
then after that run the jar
source for loop in batch file for info on loops
I see the other answer just posted, but I think you are interactive with clients playing your game, so I may pose another approach (while BufferedReader is definitely valid in some cases).
If you wanted to... you could delegate the "registration" responsibility to the client. I.e. you would have a collection of connected users with a timestamp on the last message received from each... if a client times out, you would force a re-registration of the client, but that leads to the quote and idea below.
I have read that to actually determine whether or not a socket has been closed data must be written to the output stream and an exception must be caught. This seems like a really unclean way to handle this situation.
If your Java code did not close/disconnect the Socket, then how else would you be notified that the remote host closed your connection? Ultimately, your try/catch is doing roughly the same thing that a poller listening for events on the ACTUAL socket would be doing. Consider the following:
I think one of the features of the abstracted languages is that you are abstracted from the minutia. Think of the using keyword in C# (try/finally) for SqlConnection s or whatever... it's just the cost of doing business... I think that try/catch/finally is the accepted and necesary pattern for Socket use.
This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.
var fullEntries = dbContext.tbl_EntryPoint
.Join(
dbContext.tbl_Entry,
entryPoint => entryPoint.EID,
entry => entry.EID,
(entryPoint, entry) => new { entryPoint, entry }
)
.Join(
dbContext.tbl_Title,
combinedEntry => combinedEntry.entry.TID,
title => title.TID,
(combinedEntry, title) => new
{
UID = combinedEntry.entry.OwnerUID,
TID = combinedEntry.entry.TID,
EID = combinedEntry.entryPoint.EID,
Title = title.Title
}
)
.Where(fullEntry => fullEntry.UID == user.UID)
.Take(10);
Update 11/2020: The Google Developer link is (currently) dead. The original article with a LOT more explanations can still be found at web.archive.org.
This question is already a few years old but in that time some additional possibilities have evolved, like accessing the camera directly, displaying a preview and capturing snapshots (e.g. for QR code scanning).
This Google Developers article provides an in-depth explaination of all (?) the ways how to get image/camera data into a web application, from "work everywhere" (even in desktop browsers) to "work only on modern, up-to-date mobile devices with camera". Along with many useful tips.
Explained methods:
Ask for a URL: Easiest but least satisfying.
File input (covered by most other posts here): The data can then be attached to a or manipulated with JavaScript by listening for an onchange event on the input element and then reading the files property of the event target.
<input type="file" accept="image/*" id="file-input">
<script>
const fileInput = document.getElementById('file-input');
fileInput.addEventListener('change', (e) => doSomethingWithFiles(e.target.files));
</script>
The files
property is a FileList object.
<div id="target">You can drag an image file here</div>
<script>
const target = document.getElementById('target');
target.addEventListener('drop', (e) => {
e.stopPropagation();
e.preventDefault();
doSomethingWithFiles(e.dataTransfer.files);
});
target.addEventListener('dragover', (e) => {
e.stopPropagation();
e.preventDefault();
e.dataTransfer.dropEffect = 'copy';
});
</script>
You can get a FileList
object from the dataTransfer.files
property of the drop
event.
<textarea id="target">Paste an image here</textarea>
<script>
const target = document.getElementById('target');
target.addEventListener('paste', (e) => {
e.preventDefault();
doSomethingWithFiles(e.clipboardData.files);
});
</script>
e.clipboardData.files
is a FileList
object again.
const supported = 'mediaDevices' in navigator;
and prompt the user for consent. Then show a realtime preview and copy snapshots to a canvas.<video id="player" controls autoplay></video>
<button id="capture">Capture</button>
<canvas id="canvas" width=320 height=240></canvas>
<script>
const player = document.getElementById('player');
const canvas = document.getElementById('canvas');
const context = canvas.getContext('2d');
const captureButton = document.getElementById('capture');
const constraints = {
video: true,
};
captureButton.addEventListener('click', () => {
// Draw the video frame to the canvas.
context.drawImage(player, 0, 0, canvas.width, canvas.height);
});
// Attach the video stream to the video element and autoplay.
navigator.mediaDevices.getUserMedia(constraints)
.then((stream) => {
player.srcObject = stream;
});
</script>
Don't forget to stop the video stream with
player.srcObject.getVideoTracks().forEach(track => track.stop());

Always get a positive random number.
var nexnumber = Guid.NewGuid().GetHashCode();
if (nexnumber < 0)
{
nexnumber *= -1;
}
You need to print
to get that output.
You should do
>>> x = "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])
>>> x # this is the value, returned by the join() function
'I\nwould\nexpect\nmultiple\nlines'
>>> print x # this prints your string (the type of output you want)
I
would
expect
multiple
lines
EDIT:
The info below is only applicable to VS2008 and the 3.5 framework. VS2010 has a new registry location. Further details can be found on MSDN: How to Add or Remove References in Visual Studio.
ORIGINAL
It should be listed in the .NET tab of the Add Reference dialog. Assemblies that appear there have paths in registry keys under:
HKLM\Software\Microsoft\.NETFramework\AssemblyFolders\
I have a key there named Microsoft .NET Framework 3.5 Reference Assemblies with a string value of:
C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\
Navigating there I can see the actual System.Web.Extensions dll.
EDIT:
I found my .NET 4.0 version in:
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.Extensions.dll
I'm running Win 7 64 bit, so if you're on a 32 bit OS drop the (x86).
Don't worry! This problem occurs because of the annotation. Instead of Field based access, Property based access solves this problem. The code as follows:
package onetomanymapping;
import java.util.List;
import javax.persistence.*;
@Entity
public class College {
private int collegeId;
private String collegeName;
private List<Student> students;
@OneToMany(targetEntity = Student.class, mappedBy = "college",
cascade = CascadeType.ALL, fetch = FetchType.EAGER)
public List<Student> getStudents() {
return students;
}
public void setStudents(List<Student> students) {
this.students = students;
}
@Id
@GeneratedValue
public int getCollegeId() {
return collegeId;
}
public void setCollegeId(int collegeId) {
this.collegeId = collegeId;
}
public String getCollegeName() {
return collegeName;
}
public void setCollegeName(String collegeName) {
this.collegeName = collegeName;
}
}
Use: xmlhttp.setRequestHeader(key, value);
The three options that come to mind:
1st) End void loop()
with while(1)
... or equally as good... while(true)
void loop(){
//the code you want to run once here,
//e.g., If (blah == blah)...etc.
while(1) //last line of main loop
}
This option runs your code once and then kicks the Ard into
an endless "invisible" loop. Perhaps not the nicest way to
go, but as far as outside appearances, it gets the job done.
The Ard will continue to draw current while it spins itself in
an endless circle... perhaps one could set up a sort of timer
function that puts the Ard to sleep after so many seconds,
minutes, etc., of looping... just a thought... there are certainly
various sleep libraries out there... see
e.g., Monk, Programming Arduino: Next Steps, pgs., 85-100
for further discussion of such.
2nd) Create a "stop main loop" function with a conditional control
structure that makes its initial test fail on a second pass.
This often requires declaring a global variable and having the
"stop main loop" function toggle the value of the variable
upon termination. E.g.,
boolean stop_it = false; //global variable
void setup(){
Serial.begin(9600);
//blah...
}
boolean stop_main_loop(){ //fancy stop main loop function
if(stop_it == false){ //which it will be the first time through
Serial.println("This should print once.");
//then do some more blah....you can locate all the
// code you want to run once here....eventually end by
//toggling the "stop_it" variable ...
}
stop_it = true; //...like this
return stop_it; //then send this newly updated "stop_it" value
// outside the function
}
void loop{
stop_it = stop_main_loop(); //and finally catch that updated
//value and store it in the global stop_it
//variable, effectively
//halting the loop ...
}
Granted, this might not be especially pretty, but it also works.
It kicks the Ard into another endless "invisible" loop, but this
time it's a case of repeatedly checking the if(stop_it == false)
condition in stop_main_loop()
which of course fails to pass every time after the first time through.
3rd) One could once again use a global variable but use a simple if (test == blah){}
structure instead of a fancy "stop main loop" function.
boolean start = true; //global variable
void setup(){
Serial.begin(9600);
}
void loop(){
if(start == true){ //which it will be the first time through
Serial.println("This should print once.");
//the code you want to run once here,
//e.g., more If (blah == blah)...etc.
}
start = false; //toggle value of global "start" variable
//Next time around, the if test is sure to fail.
}
There are certainly other ways to "stop" that pesky endless main loop but these three as well as those already mentioned should get you started.

Technically, this is the same answer as @Sujee. It also depends on your version of Oracle as to whether it works. (I think this syntax was introduced in Oracle 12??)
SELECT *
FROM table
ORDER BY value DESC, date_column ASC
FETCH first 1 rows only;
As I say, if you look under the bonnet, I think this code is unpacked internally by the Oracle Optimizer to read like @Sujee's. However, I'm a sucker for pretty coding, and nesting select
statements without a good reason does not qualify as beautiful!! :-P
Try this...
if(string1.toLowerCase() == string2.toLowerCase()){
return true;
}
Also, it's not a loop, it's a block of code. Loops are generally repeated (although they can possibly execute only once), whereas a block of code never repeats.
I read your note about not using toLowerCase, but can't see why it would be a problem.
To create a property class please select your package where you wants to create your property file.
Right click on the package and select other. Now select File and type your file name with (.properties) suffix. For example: db.properties. Than click finish. Now you can write your code inside this property file.
A very simple example:
SET a=Hello
SET b=World
SET c=%a% %b%!
echo %c%
The result should be:
Hello World!
Looks like there are two things at play here:
I will address each separately.
Basically, in onBindViewHolder
you are given an already initialized ViewHolder
, which already contains a view. That ViewHolder
may or may not have been previously bound to some data!
Note this bit of code right here:
holder.checkBox.setChecked(fonts.get(position).isSelected());
If the holder has been previously bound, then the checkbox already has a listener for when the checked state changes! That listener is being triggered at this point, which is what was causing your IllegalStateException
.
An easy solution would be to remove the listener before calling setChecked
. An elegant solution would require more knowledge of your views - I encourage you to look for a nicer way of handling this.
The listener in your code is changing the state of the data without notifying the adapter of any subsequent changes. I don't know how your views are working so this may or may not be an issue. Typically when the state of your data changes, you need to let the adapter know about it.
RecyclerView.Adapter
has many options to choose from, including notifyItemChanged
, which tells it that a particular item has changed state. This might be good for your use
if(isChecked) {
for (int i = 0; i < fonts.size(); i++) {
if (i == position) continue;
Font f = fonts.get(i);
if (f.isSelected()) {
f.setSelected(false);
notifyItemChanged(i); // Tell the adapter this item is updated
}
}
fonts.get(position).setSelected(isChecked);
notifyItemChanged(position);
}
In a situation where you have this:
enum fruit {
apple,
orange,
grape,
banana,
// etc.
};
I like to put this in the header file where the enum is defined:
static inline char *stringFromFruit(enum fruit f)
{
static const char *strings[] = { "apple", "orange", "grape", "banana", /* continue for rest of values */ };
return strings[f];
}
Tail Recursion is pretty fast as compared to normal recursion. It is fast because the output of the ancestors call will not be written in stack to keep the track. But in normal recursion all the ancestor calls output written in stack to keep the track.
You may not like it, but personally I find
if (x.HasValue && x.Value)
the most readable. It makes it clear you are working with a nullable type and it makes it clear you are first checking whether the nullable type has a value before acting on it conditionally.
If you take your version and replace the variable with x also it reads:
if (x ?? false)
Is that as clear? Is it obvious x is a nullable type? I'll let you decide.
I had problems with this recently, i use this code and work fine for me.
var data = 'Peter';
db.User.find({'name' : new RegExp(data, 'i')}, function(err, docs){
cb(docs);
});
Use directly /Peter/i
work, but i use '/'+data+'/i'
and not work for me.
You can make virtualenvwrapper use a custom Python binary instead of the one virtualenvwrapper is run with. To do that you need to use VIRTUALENV_PYTHON variable which is utilized by virtualenv:

2020 Update:
For current Debian/Ubuntu, use
apt-get install python3-pip
to install pip3
.
Old 2013 answer (easy_install is now deprecated):
Use setuptools to install pip: sudo easy_install pip
(I know the above part of my answer is redundant with klobucar's, but I can't add comments yet), so here's an answer with a solution to sudo: easy_install: command not found
on Debian/Ubuntu:sudo apt-get install python-setuptools
Also, for python3, use easy_install3
and python3-setuptools
.
For Python 3, use apt-get install python3-pip
.
The python error says that wordInput
is not an iterable -> it is of NoneType.
If you print wordInput
before the offending line, you will see that wordInput
is None
.
Since wordInput
is None
, that means that the argument passed to the function is also None
. In this case word
. You assign the result of pickEasy
to word
.
The problem is that your pickEasy
function does not return anything. In Python, a method that didn't return anything returns a NoneType.
I think you wanted to return a word
, so this will suffice:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
It depends on what you're trying to achieve after changing the Java file. Until you want to test the maven process, you never need to do anything. Eclipse/MyEclipse will build what is necessary and put the output in the appropriate place within your project. You can also run or deploy it (if it's a web project, for example), without your needing to explicitly do anything with maven. In the end, to install your project in the maven repository, you will need to do a maven install. You may also have other maven goals that you wish to execute, which MyEclipse won't do automatically.
As I say, it depends on what you want to do.
Expanding on betabandido's answer, you could write a function to inject the attributes as constants into the module:
def module_register_class_constants(klass, attr_prefix):
globals().update(
(name, getattr(klass, name)) for name in dir(klass) if name.startswith(attr_prefix)
)
class Animal(object):
SIZE_HUGE = "Huge"
SIZE_BIG = "Big"
module_register_class_constants(Animal, "SIZE_")
class Horse(Animal):
def printSize(self):
print SIZE_BIG

Note (as of 2020-08-04): this solution does not appear to work in iOS Safari v12+. I will update this answer and delete this note once I find a clear solution that covers iOS Safari.
CSS-only solution
Add touch-action: manipulation
to any element on which you want to disable double tap zoom, like with the following disable-dbl-tap-zoom
class:
.disable-dbl-tap-zoom {
touch-action: manipulation;
}
From the touch-action
docs (emphasis mine):
manipulation
Enable panning and pinch zoom gestures, but disable additional non-standard gestures such as double-tap to zoom.
This value works on Android and on iOS.
You still need two INSERT
statements, but it sounds like you want to get the IDENTITY
from the first insert and use it in the second, in which case, you might want to look into OUTPUT
or OUTPUT INTO
