I have tried it, it works for you.
String mainWinHander = webDriver.getWindowHandle();
// code for clicking button to open new window is ommited
//Now the window opened. So here reture the handle with size = 2
Set<String> handles = webDriver.getWindowHandles();
for(String handle : handles)
{
if(!mainWinHander.equals(handle))
{
// Here will block for ever. No exception and timeout!
WebDriver popup = webDriver.switchTo().window(handle);
// do something with popup
popup.close();
}
}
You create a primary key on your fields and let the engine enforce the uniqueness. Doing IF EXISTS logic is incorrect anyway as is flawed with race conditions.
Recursive is the current default two-head strategy, but after some searching I finally found some info about the "resolve" merge strategy.
Taken from O'Reilly book Version Control with Git (Amazon) (paraphrased):
Originally, "resolve" was the default strategy for Git merges.
In criss-cross merge situations, where there is more than one possible merge basis, the resolve strategy works like this: pick one of the possible merge bases, and hope for the best. This is actually not as bad as it sounds. It often turns out that the users have been working on different parts of the code. In that case, Git detects that it's remerging some changes that are already in place and skips the duplicate changes, avoiding the conflict. Or, if these are slight changes that do cause conflict, at least the conflict should be easy for the developer to handle..
I have successfully merged trees using "resolve" that failed with the default recursive strategy. I was getting fatal: git write-tree failed to write a tree
errors, and thanks to this blog post (mirror) I tried "-s resolve", which worked. I'm still not exactly sure why... but I think it was because I had duplicate changes in both trees, and resolve "skipped" them properly.

Here's an Apple developer link that explicitly says that -
on iPhone and iPod touch, which are small screen devices, "Video is NOT presented within the Web Page"
Safari Device-Specific Considerations
Your options:
webkit-playsinline
attribute works for HTML5 videos on iOS but only when you save the webpage to your home screen as a webapp - Not if opened a page in SafariUIWebView
allows to play the video inline, but only if you set the allowsInlineMediaPlayback
property for the UIWebView
class to trueThis is fastest way to do it:
let thisVar = false
if (thisVar === false) {
throw new Error("thisVar is false. It should be true.")
}
Works for me on Chrome on Mac. Seems to be or simpler or more reliable (in case userAgent string tested) than all above.
var isChrome = false;
if (window.chrome && !window.opr){
isChrome = true;
}
console.log(isChrome);

If you are using Mysql with Hibernate v3 it's ok to use GenerationType.AUTO
because internally it will use GenerationType.IDENTITY
, which is the most optimal in for MySQL.
However in Hibernate v5, It has changed. GenerationType.AUTO
will use GenerationType.TABLE
which generates to much queries for the insertion.
You can avoid that using GenerationType.IDENTITY
(if MySQL is the only database you are using) or with these notations (if you have multiple databases):
@GeneratedValue(strategy = GenerationType.AUTO, generator = "native")
@GenericGenerator(name = "native", strategy = "native")
If you mean to change default directory for "Node.js command prompt", when you launch it, then (Windows case)
change the default path in the row which looks like
if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
with your path. It could be for example
if "%CD%\"=="%~dp0" cd /d "c://MyDirectory/"
if you mean to change directory once when you launched "Node.js command prompt", then execute the following command in the Node.js command prompt:
cd c:/MyDirectory/
If you are looking for retrieving remote user IDSID/Username, use:
echo gethostbyaddr($_SERVER['REMOTE_ADDR']);
You will get something like iamuser1-mys.corp.company.com
Filter the rest of the domain behind, and you are able to get the idsid only.

From the documentation of XPath ( http://www.w3.org/TR/xpath/#location-paths ):
child::*
selects all element children of the context node
child::text()
selects all text node children of the context node
child::node()
selects all the children of the context node, whatever their node type
So I guess your answer is:
$doc/PRESENTEDIN/X/child::node()
And if you want a flatten array of all nested nodes:
$doc/PRESENTEDIN/X/descendant::node()
You can use ng-change instead of ng-click:
<!doctype html>
<html>
<head>
<script src="http://code.angularjs.org/1.2.3/angular.min.js"></script>
<script>
var app = angular.module('myapp', []);
app.controller('mainController', function($scope) {
$scope.vm = {};
$scope.vm.myClick = function($event) {
alert($event);
}
});
</script>
</head>
<body ng-app="myapp">
<div ng-controller="mainController">
<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
</div>
</body>
</html>
Open Control Panel >> Network and Sharing Center. Now click on Change Adapter Settings. Right click on the adapter whose Name or the Device Name matches with VirtualBox Host-Only Ethernet Adapter # 3 and click on Properties. Click on the Configure button.
Now click on the Driver tab. Click on Update Driver. Select Browse my computer for drivers. Now choose Let me pick from a list of available drivers on my computer. Select the choice you get and click on Next. Click Close to finish the update. Now go back to your Terminal/Powershell/Command window and repeat the vagrant up command. It should work fine this time.

According to getBootstrap.com, dropdowns are built on third-party library Popper.js. So, if the dropdown menu does not work onclick but is working only on hover of the dropdown include popper.js, bootstrap.js and bootstrap.css. Not including popper.js before including bootstrap bundles could be one of the reasons.
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js"></script>

Whilst, as has been pointed out, it is possible to see the current default socket buffer sizes in /proc
, it is also possible to check them using sysctl
(Note: Whilst the name includes ipv4 these sizes also apply to ipv6 sockets - the ipv6 tcp_v6_init_sock() code just calls the ipv4 tcp_init_sock() function):
sysctl net.ipv4.tcp_rmem
sysctl net.ipv4.tcp_wmem
However, the default socket buffers are just set when the sock is initialised but the kernel then dynamically sizes them (unless set using setsockopt() with SO_SNDBUF). The actual size of the buffers for currently open sockets may be inspected using the ss
command (part of the iproute
package), which can also provide a bunch more info on sockets like congestion control parameter etc. E.g. To list the currently open TCP (t
option) sockets and associated memory (m
) information:
ss -tm
Here's some example output:
State Recv-Q Send-Q Local Address:Port Peer Address:Port
ESTAB 0 0 192.168.56.102:ssh 192.168.56.1:56328
skmem:(r0,rb369280,t0,tb87040,f0,w0,o0,bl0,d0)
Here's a brief explanation of skmem (socket memory) - for more info you'll need to look at the kernel sources (e.g. sock.h):
r:sk_rmem_alloc rb:sk_rcvbuf # current receive buffer size t:sk_wmem_alloc tb:sk_sndbuf # current transmit buffer size f:sk_forward_alloc w:sk_wmem_queued # persistent transmit queue size o:sk_omem_alloc bl:sk_backlog d:sk_drops
If you need to read all values from a section in properties file in a simple manner:
Your config.cfg
file layout :
[SECTION_NAME]
key1 = value1
key2 = value2
You code:
import configparser
config = configparser.RawConfigParser()
config.read('path_to_config.cfg file')
details_dict = dict(config.items('SECTION_NAME'))
This will give you a dictionary where keys are same as in config file and their corresponding values.
details_dict
is :
{'key1':'value1', 'key2':'value2'}
Now to get key1's value :
details_dict['key1']
Putting it all in a method which reads sections from config file only once(the first time the method is called during a program run).
def get_config_dict():
if not hasattr(get_config_dict, 'config_dict'):
get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
return get_config_dict.config_dict
Now call the above function and get the required key's value :
config_details = get_config_dict()
key_1_value = config_details['key1']
Generic Multi Section approach:
[SECTION_NAME_1]
key1 = value1
key2 = value2
[SECTION_NAME_2]
key1 = value1
key2 = value2
Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.
def get_config_section():
if not hasattr(get_config_section, 'section_dict'):
get_config_section.section_dict = collections.defaultdict()
for section in config.sections():
get_config_section.section_dict[section] = dict(config.items(section))
return get_config_section.section_dict
To access:
config_dict = get_config_section()
port = config_dict['DB']['port']
(here 'DB' is a section name in config file and 'port' is a key under section 'DB'.)
Here's a way to do this as a JQuery plugin (in case you want to re-use the functionality):
$.fn.onEnterKey =
function( closure ) {
$(this).keypress(
function( event ) {
var code = event.keyCode ? event.keyCode : event.which;
if (code == 13) {
closure();
return false;
}
} );
}
Now if you want to decorate an <input>
element with this type of functionality it's as simple as this:
$('#your-input-id').onEnterKey(
function() {
// Do stuff here
} );
There are many great libraries out there, for those interested
There really shouldn't be a need these days to invent your own formatting specifiers.

I have found a crossbrowser compatible JQuery plugin here.
http://designwithpc.com/Plugins/ddSlick
probably useful in this scenario.
From further research, I've found:
http://dev.mysql.com/doc/refman/5.1/en/news-5-1-11.html
An SQL-injection security hole has been found in multi-byte encoding processing. The bug was in the server, incorrectly parsing the string escaped with the mysql_real_escape_string() C API function.
This vulnerability was discovered and reported by Josh Berkus and Tom Lane as part of the inter-project security collaboration of the OSDB consortium. For more information about SQL injection, please see the following text.
Discussion. An SQL injection security hole has been found in multi-byte encoding processing. An SQL injection security hole can include a situation whereby when a user supplied data to be inserted into a database, the user might inject SQL statements into the data that the server will execute. With regards to this vulnerability, when character set-unaware escaping is used (for example, addslashes() in PHP), it is possible to bypass the escaping in some multi-byte character sets (for example, SJIS, BIG5 and GBK). As a result, a function such as addslashes() is not able to prevent SQL-injection attacks. It is impossible to fix this on the server side. The best solution is for applications to use character set-aware escaping offered by a function such mysql_real_escape_string().
However, a bug was detected in how the MySQL server parses the output of mysql_real_escape_string(). As a result, even when the character set-aware function mysql_real_escape_string() was used, SQL injection was possible. This bug has been fixed.
Workarounds. If you are unable to upgrade MySQL to a version that includes the fix for the bug in mysql_real_escape_string() parsing, but run MySQL 5.0.1 or higher, you can use the NO_BACKSLASH_ESCAPES SQL mode as a workaround. (This mode was introduced in MySQL 5.0.1.) NO_BACKSLASH_ESCAPES enables an SQL standard compatibility mode, where backslash is not considered a special character. The result will be that queries will fail.
To set this mode for the current connection, enter the following SQL statement:
SET sql_mode='NO_BACKSLASH_ESCAPES';
You can also set the mode globally for all clients:
SET GLOBAL sql_mode='NO_BACKSLASH_ESCAPES';
This SQL mode also can be enabled automatically when the server starts by using the command-line option --sql-mode=NO_BACKSLASH_ESCAPES or by setting sql-mode=NO_BACKSLASH_ESCAPES in the server option file (for example, my.cnf or my.ini, depending on your system). (Bug#8378, CVE-2006-2753)

Few years later, want to suggest just
for this: https://github.com/casey/just
action v1 v2=default:
@echo 'take action on {{v1}} and {{v2}}...'
My solution was:
for me command rm /usr/local/var/postgres/postmaster.pid
didn't work cause I installed a specific version of postgresql with homebrew.
the right command is rm /usr/local/var/postgres@10/postmaster.pid
.
then brew services restart postgresql@10
.
As mentioned by @Vivek Solanki, I also uploaded my file on the colaboratory dashboard under "File" section.
Just take a note of where the file has been uploaded. For me,
train_data = pd.read_csv('/fileName.csv')
worked.
Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler
, which defines a method that is invoked when a proxy method is invoked.
You create them by using the call
Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
The arguments are:
classLoader
. Once the class is generated, it is loaded with this class loader.interfaces
. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.invocationHandler
. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler
. When a method from any of the supported interfaces, or hashCode
, equals
, or toString
, is invoked, the method invoke
is invoked on the handler, passing the Method
object for the method to be invoked and the arguments passed.For more on this, see the documentation for the Proxy
class.
Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.
You should try doing it with css3 animation. Check the code bellow:

-webkit-animation-direction: alternate; /* Chrome, Safari, Opera */
animation: myfirst 5s infinite;
animation-direction: alternate;
}
/* Chrome, Safari, Opera */
@-webkit-keyframes myfirst {
0% {background: red; left: 0px; top: 0px;}
25% {background: yellow; left: 200px; top: 0px;}
50% {background: blue; left: 200px; top: 200px;}
75% {background: green; left: 0px; top: 200px;}
100% {background: red; left: 0px; top: 0px;}
}
@keyframes myfirst {
0% {background: red; left: 0px; top: 0px;}
25% {background: yellow; left: 200px; top: 0px;}
50% {background: blue; left: 200px; top: 200px;}
75% {background: green; left: 0px; top: 200px;}
100% {background: red; left: 0px; top: 0px;}
}
</style>
</head>
<body>
<p><strong>Note:</strong> The animation-direction property is not supported in Internet Explorer 9 and earlier versions.</p>
<div></div>
</body>
</html>
Where 'div' is your animated object.
I hope you find this useful.
Thanks.
promises
, a JavaScript feature of the ECMAScript 6
standard. If your target platform does not support promises
, polyfill it with PromiseJs.You can get the Deferred
object jQuery creates for the animation using .promise()
on the animation call. Wrapping these Deferreds
into ES6 Promises
results in much cleaner code than using timers.
You can also use Deferreds
directly, but this is generally discouraged because they do not follow the Promises/A+ specification.
The resulting code would look like this:
var p1 = Promise.resolve($('#Content').animate({ opacity: 0.5 }, { duration: 500, queue: false }).promise());
var p2 = Promise.resolve($('#Content').animate({ marginLeft: "-100px" }, { duration: 2000, queue: false }).promise());
Promise.all([p1, p2]).then(function () {
return $('#Content').animate({ width: 0 }, { duration: 500, queue: false }).promise();
});
Note that the function in Promise.all()
returns the promise. This is where magic happens. If in a then
call a promise is returned, the next then
call will wait for that promise to be resolved before executing.
jQuery uses an animation queue for each element. So animations on the same element are executed synchronously. In this case you wouldn't have to use promises at all!
I have disabled the jQuery animation queue to demonstrate how it would work with promises.
Promise.all()
takes an array of promises and creates a new Promise
that finishes after all promises in the array finished.
Promise.race()
also takes an array of promises, but finishes as soon as the first Promise
finished.

The accepted answer currently fires twice for animations in Chrome. Presumably this is because it recognizes webkitAnimationEnd
as well as animationEnd
. The following will definitely only fires once:
/* From Modernizr */
function whichTransitionEvent(){
var el = document.createElement('fakeelement');
var transitions = {
'animation':'animationend',
'OAnimation':'oAnimationEnd',
'MSAnimation':'MSAnimationEnd',
'WebkitAnimation':'webkitAnimationEnd'
};
for(var t in transitions){
if( transitions.hasOwnProperty(t) && el.style[t] !== undefined ){
return transitions[t];
}
}
}
$("#elementToListenTo")
.on(whichTransitionEvent(),
function(e){
console.log('Transition complete! This is the callback!');
$(this).off(e);
});
The server_name
docs directive is used to identify virtual hosts, they're not used to set the binding.
netstat
tells you that nginx listens on 0.0.0.0:80
which means that it will accept connections from any IP.
If you want to change the IP nginx binds on, you have to change the listen
docs rule.
So, if you want to set nginx to bind to localhost
, you'd change that to:
listen 127.0.0.1:80;
In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).
Since hashes aren't inherently ordered, there isn't a notion of appending. Ruby hashes since 1.9 maintain insertion order, however. Here are the ways to add new key/value pairs.
The simplest solution is
h[:key] = "bar"
If you want a method, use store
:
h.store(:key, "bar")
If you really, really want to use a "shovel" operator (<<
), it is actually appending to the value of the hash as an array, and you must specify the key:
h[:key] << "bar"
The above only works when the key exists. To append a new key, you have to initialize the hash with a default value, which you can do like this:
h = Hash.new {|h, k| h[k] = ''}
h[:key] << "bar"
You may be tempted to monkey patch Hash to include a shovel operator that works in the way you've written:
class Hash
def <<(k,v)
self.store(k,v)
end
end
However, this doesn't inherit the "syntactic sugar" applied to the shovel operator in other contexts:
h << :key, "bar" #doesn't work
h.<< :key, "bar" #works
something like this

"Better" is subjective.
querySelector
is the newer feature.
getElementById
is better supported than querySelector
.
querySelector
is better supported than getElementsByClassName
.
querySelector
lets you find elements with rules that can't be expressed with getElementById
and getElementsByClassName
You need to pick the appropriate tool for any given task.
(In the above, for querySelector
read querySelector
/ querySelectorAll
).
I had the same problem and, in my case, the problem was that python was looking for packages in some ordered locations, first of all the default computer one where default old packages are.
To check what your python is looking for you can do:
>>> import sys
>>> print '\n'.join(sys.path)
This was outputting the directory '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python' before pip or brew or port folders.
The simple solution is:
export PYTHONPATH="/Library/Python/2.7/site-packages:$PYTHONPATH"
This worked well for me, I advise you to add this line to your home bash_profile file for the next time. Remember that sys.path is built using the current working directory, followed by the directories in the PYTHONPATH environment variable. Then there are the installation-dependent default dirs.
Rclone is what you are looking for. Rclone ("rsync for cloud storage") is a command line program to sync files and directories to and from different cloud storage providers including local filesystems. Rclone was previously known as Swiftsync and has been available since 2013.
All other answers don't quite solve the issue. They print the date formatted as mm/dd/yyyy but the question was regarding MM/dd/yyyy. Notice the subtle difference? MM indicates that a leading zero must pad the month if the month is a single digit, thus having it always be a double digit number.
i.e. whereas mm/dd would be 3/31, MM/dd would be 03/31.
I've created a simple function to achieve this. Notice that the same padding is applied not only to the month but also to the day of the month, which in fact makes this MM/DD/yyyy:
function getFormattedDate(date) {_x000D_
var year = date.getFullYear();_x000D_
_x000D_
var month = (1 + date.getMonth()).toString();_x000D_
month = month.length > 1 ? month : '0' + month;_x000D_
_x000D_
var day = date.getDate().toString();_x000D_
day = day.length > 1 ? day : '0' + day;_x000D_
_x000D_
return month + '/' + day + '/' + year;_x000D_
}
_x000D_
Update for ES2017 using String.padStart(), supported by all major browsers except IE.
function getFormattedDate(date) {_x000D_
let year = date.getFullYear();_x000D_
let month = (1 + date.getMonth()).toString().padStart(2, '0');_x000D_
let day = date.getDate().toString().padStart(2, '0');_x000D_
_x000D_
return month + '/' + day + '/' + year;_x000D_
}
_x000D_
Above example is technically incorrect. Per latest jQuery, use the prop()
method should be used for things like disabled. See their API page.
To disable all form elements inside 'target', use the :input selector which matches all input, textarea, select and button elements.
$("#target :input").prop("disabled", true);
If you only want the elements, use this.
$("#target input").prop("disabled", true);

var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = new Date();_x000D_
};_x000D_
_x000D_
function end() {_x000D_
endTime = new Date();_x000D_
var timeDiff = endTime - startTime; //in ms_x000D_
// strip the ms_x000D_
timeDiff /= 1000;_x000D_
_x000D_
// get seconds _x000D_
var seconds = Math.round(timeDiff);_x000D_
console.log(seconds + " seconds");_x000D_
}
_x000D_
<button onclick="start()">Start</button>_x000D_
_x000D_
<button onclick="end()">End</button>
_x000D_
OR another way of doing it for modern browser
Using performance.now()
which returns a value representing the time elapsed since the time origin. This value is a double with microseconds in the fractional.
The time origin is a standard time which is considered to be the beginning of the current document's lifetime.
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = performance.now();_x000D_
};_x000D_
_x000D_
function end() {_x000D_
endTime = performance.now();_x000D_
var timeDiff = endTime - startTime; //in ms _x000D_
// strip the ms _x000D_
timeDiff /= 1000; _x000D_
_x000D_
// get seconds _x000D_
var seconds = Math.round(timeDiff);_x000D_
console.log(seconds + " seconds");_x000D_

Issue #2 now can be solved using BroadcastAPI.
At the moment it's only available in Chrome, Firefox, and Opera.
var bc = new BroadcastChannel('test_channel');
bc.onmessage = function (ev) {
if(ev.data && ev.data.url===window.location.href){
alert('You cannot open the same page in 2 tabs');
}
}
bc.postMessage(window.location.href);
There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.
And then you can copy for example the file "test.txt" from a remote host to the local host
scp [email protected]:test.txt /local/dir
@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.
In UNIX, absolute paths must start with '/'.
AJAX file uploads are now possible by passing a FormData
object to the data
property of the $.ajax
request.
As the OP specifically asked for a jQuery implementation, here you go:
<form id="upload" enctype="multipart/form-data" action="@Url.Action("JsonSave", "Survey")" method="POST">
<input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
<button>Upload!</button>
</form>
$('#upload').submit(function(e) {
e.preventDefault(); // stop the standard form submission
$.ajax({
url: this.action,
type: this.method,
data: new FormData(this),
cache: false,
contentType: false,
processData: false,
success: function (data) {
console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
},
error: function(xhr, error, status) {
console.log(error, status);
}
});
});
public JsonResult Survey()
{
for (int i = 0; i < Request.Files.Count; i++)
{
var file = Request.Files[i];
// save file as required here...
}
return Json(new { UploadedFileCount = Request.Files.Count });
}
More information on FormData at MDN
public static String formateDate(String dateString) {
Date date;
String formattedDate = "";
try {
date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss",Locale.getDefault()).parse(dateString);
formattedDate = new SimpleDateFormat("dd/MM/yyyy",Locale.getDefault()).format(date);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return formattedDate;
}
C# does have a preprocessor. It works just slightly differently than that of C++ and C.
Here is a MSDN links - the section on all preprocessor directives.
Not yet (as of September, 2019), but since the "safe navigation operator" is now at Stage 3, it's being implemented in TypeScript.
Watch this issue for updates:
https://github.com/microsoft/TypeScript/issues/16
Several engines have early implementations:

You can install a plugin to support it now:
npm install --save-dev ts-optchain
In your tsconfig.json:
// tsconfig.json
{
"compilerOptions": {
"plugins": [
{ "transform": "ts-optchain/transform" },
]
},

tips
in package.json
:
"scripts": {
"start": "set NODE_ENV=dev && node app.js"
}
in app.js
:
console.log(process.env.NODE_ENV) // dev
console.log(process.env.NODE_ENV === 'dev') // false
console.log(process.env.NODE_ENV.length) // 4 (including a space at the end)
so, this may better:
"start": "set NODE_ENV=dev&& node app.js"
or
console.log(process.env.NODE_ENV.trim() === 'dev') // true
For special character I normally use the Unicode definition, for the '&' for example: \u0026 if I am correct. Here is a nice reference page: http://jrgraphix.net/research/unicode_blocks.php?block=0

Using ImageMagick, this is very similar to hackerb9 code and result, but is a little simpler command line. It does assume that the top left pixel is the background color. I just flood fill the background with transparency, then select the alpha channel and blur it and remove half of the blurred area using -level 50x100%. Then turn back on all the channels and flatten it against the brown color. The -blur 0x1 -level 50x100% acts to antialias the boundaries of the alpha channel transparency. You can adjust the fuzz value, blur amount and the -level 50% value to change the degree of antialiasing.

The problem might be with service mysql-server and apache2 running while system start. You can do the following.
sudo /opt/lampp/lampp stop
To stop already running default services
sudo service apache2 stop
sudo service mysql stop
To remove the services completely, so that they won't create problem in next system-restart, If you are in ubuntu(debian)
sudo apt-get remove apache2
sudo apt-get remove mysql-server
If you are in redhat or other, You could use yum
or similar command to uninstall the services
Then start the lampp again
sudo /opt/lampp/lampp start
Also, don't install mysql-server in the system, because it might start in system start-up, occupy the port, and create problem for mysql of lampp.
We should have the projects which include (at least) all the filtered tags, or said in a different way, exclude the ones which doesn't include all those filtered tags.
So we can use Linq Except
to get those tags which are not included. Then we can use Count() == 0
to have only those which excluded no tags:
var res = projects.Where(p => filteredTags.Except(p.Tags).Count() == 0);
Or we can make it slightly faster with by replacing Count() == 0
with !Any()
:
var res = projects.Where(p => !filteredTags.Except(p.Tags).Any());
Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).
I recommend you using the stdlib module urllib2
, it will allow you to comfortably get web resources.
Example:
import urllib2
response = urllib2.urlopen("http://google.de")
page_source = response.read()
For parsing the code, have a look at BeautifulSoup
.
BTW: what exactly do you want to do:
Just for background, I need to download a page and replace any img with ones I have
Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests
is a very nice high-level library which is easier to use than urllib2
.
.val()
or .value
is IMHO the best solution because it's useful with Ajax. And .reset()
only works after page reload and APIs using Ajax never refresh pages unless it's triggered by a different script.
Simple date example using $filter in a controller would be:
var myDate = new Date();
$scope.dateAsString = $filter('date')(myDate, "yyyy-MM-dd");
As explained here - https://stackoverflow.com/a/20131782/262140
Lot's of people say to just use the "Pass an object" trick so that you have named parameters.
/**
* My Function
*
* @param {Object} arg1 Named arguments
*/
function myFunc(arg1) { }
myFunc({ param1 : 70, param2 : 175});
And that works great, except..... when it comes to most IDEs out there, a lot of us developers rely on type / argument hints within our IDE. I personally use PHP Storm (Along with other JetBrains IDEs like PyCharm for python and AppCode for Objective C)
And the biggest problem with using the "Pass an object" trick is that when you are calling the function, the IDE gives you a single type hint and that's it... How are we supposed to know what parameters and types should go into the arg1 object?
So... the "Pass an object" trick doesn't work for me... It actually causes more headaches with having to look at each function's docblock before I know what parameters the function expects.... Sure, it's great for when you are maintaining existing code, but it's horrible for writing new code.
Well, this is the technique I use.... Now, there may be some issues with it, and some developers may tell me I'm doing it wrong, and I have an open mind when it comes to these things... I am always willing to look at better ways of accomplishing a task... So, if there is an issue with this technique, then comments are welcome.
/**
* My Function
*
* @param {string} arg1 Argument 1
* @param {string} arg2 Argument 2
*/
function myFunc(arg1, arg2) { }
var arg1, arg2;
myFunc(arg1='Param1', arg2='Param2');
This way, I have the best of both worlds... new code is easy to write as my IDE gives me all the proper argument hints... And, while maintaining code later on, I can see at a glance, not only the value passed to the function, but also the name of the argument. The only overhead I see is declaring your argument names as local variables to keep from polluting the global namespace. Sure, it's a bit of extra typing, but trivial compared to the time it takes to look up docblocks while writing new code or maintaining existing code.
What worked for me tho is this library https://pypi.org/project/silence-tensorflow/
Install this library and do as instructed on the page, it works like a charm!

No need to mess around with settings just remove the quotes and spaces from the font-family:
this
body {font-family: "DroidSerif Regular", serif; }
becomes this
body {font-family: DroidSerifRegular, serif; }
see below code it may help you.
String q = "SELECT * FROM customer";
Cursor mCursor = mDb.rawQuery(q, null);
or
String q = "SELECT * FROM customer WHERE _id = " + customerDbId ;
Cursor mCursor = mDb.rawQuery(q, null);
Use the following syntax:
$ for i in {01..05}; do echo "$i"; done
01
02
03
04
05
Disclaimer: Leading zeros only work in >=bash-4
.
If you want to use printf
, nothing prevents you from putting its result in a variable for further use:
$ foo=$(printf "%02d" 5)
$ echo "${foo}"
05
If the array element is not integer you can use something like below :
$skus = array('LDRES10','LDRES12','LDRES11'); //sample data
if(!empty($skus)){
$sql = "SELECT * FROM `products` WHERE `prodCode` IN ('" . implode("','", $skus) . "') "
}
^\w{0,10}$ # allows words of up to 10 characters.
^\w{5,}$ # allows words of more than 4 characters.
^\w{5,10}$ # allows words of between 5 and 10 characters.

I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).
I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.
[Desktop Entry]
Name=No name
Encoding=UTF-8
Version=1.0
Exec=vncconfig -nowin
X-GNOME-Autostart-enabled=true
Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.
Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.
If you're copying data like that, that probably means your datamodel isn't fully normalized, right? Is it possible to make one list of countries and do a JOIN more?
Instead of a JOIN you could also use virtual tables so you don't have to change the queries in your system.
I found that the selected answer works for the browser apps but I was having issues with the code working in non browser apps that implement a UIWebView
.
The problem for me was a user on the Twitter app would click a link that would take them to my site through a UIWebView
in the Twitter app. Then when they clicked a button from my site Twitter tries to be fancy and only complete the window.location
if the site is reachable. So what happens is a UIAlertView
pops up saying are you sure you want to continue and then immediately redirects to the App Store without a second popup.
My solution involves iframes. This avoids the UIAlertView
being presented allowing for a simple and elegant user experience.
jQuery
var redirect = function (location) {
$('body').append($('<iframe></iframe>').attr('src', location).css({
width: 1,
height: 1,
position: 'absolute',
top: 0,
left: 0
}));
};
setTimeout(function () {
redirect('http://itunes.apple.com/app/id');
}, 25);
redirect('custom-uri://');
Javascript
var redirect = function (location) {
var iframe = document.createElement('iframe');
iframe.setAttribute('src', location);
iframe.setAttribute('width', '1px');
iframe.setAttribute('height', '1px');
iframe.setAttribute('position', 'absolute');
iframe.setAttribute('top', '0');
iframe.setAttribute('left', '0');
document.documentElement.appendChild(iframe);
iframe.parentNode.removeChild(iframe);
iframe = null;
};
setTimeout(function () {
redirect('http://itunes.apple.com/app/id');
}, 25);
redirect('custom-uri://');
EDIT:
Add position absolute to the iframe so when inserted there isn't a random bit of whitespace at the bottom of the page.
Also it's important to note that I have not found a need for this approach with Android. Using window.location.href
should work fine.
That ibdata1
isn't shrinking is a particularly annoying feature of MySQL. The ibdata1
file can't actually be shrunk unless you delete all databases, remove the files and reload a dump.
But you can configure MySQL so that each table, including its indexes, is stored as a separate file. In that way ibdata1
will not grow as large. According to Bill Karwin's comment this is enabled by default as of version 5.6.6 of MySQL.
It was a while ago I did this. However, to setup your server to use separate files for each table you need to change my.cnf
in order to enable this:
[mysqld]
innodb_file_per_table=1
https://dev.mysql.com/doc/refman/5.6/en/innodb-file-per-table-tablespaces.html
As you want to reclaim the space from ibdata1
you actually have to delete the file:
mysqldump
of all databases, procedures, triggers etc except the mysql
and performance_schema
databasesibdata1
and ib_log
filesWhen you start MySQL in step 5 the ibdata1
and ib_log
files will be recreated.
Now you're fit to go. When you create a new database for analysis, the tables will be located in separate ibd*
files, not in ibdata1
. As you usually drop the database soon after, the ibd*
files will be deleted.
http://dev.mysql.com/doc/refman/5.1/en/drop-database.html
You have probably seen this:
http://bugs.mysql.com/bug.php?id=1341
By using the command ALTER TABLE <tablename> ENGINE=innodb
or OPTIMIZE TABLE <tablename>
one can extract data and index pages from ibdata1 to separate files. However, ibdata1 will not shrink unless you do the steps above.
Regarding the information_schema
, that is not necessary nor possible to drop. It is in fact just a bunch of read-only views, not tables. And there are no files associated with the them, not even a database directory. The informations_schema
is using the memory db-engine and is dropped and regenerated upon stop/restart of mysqld. See https://dev.mysql.com/doc/refman/5.7/en/information-schema.html.

I found a solution for how to set a global variable in a mailinglist posting via assign:
a <- "old"
test <- function () {
assign("a", "new", envir = .GlobalEnv)
}
test()
a # display the new value
If you load the document in Chrome, the Developer|Elements
view will show you the HTML as fiddled by your JS code. It's not directly HTML text and you have to open (unfold) any elements of interest, but you effectively get to inspect the generated HTML.
Try to use the rack-cors gem. And add the header field in your Ajax call.
I used a combination of the above to achieve a working result; Change float to Left and display Block the li itself HTML:
<ol class="foo">
<li>bar1</li>
<li>bar2</li>
</ol>
CSS:
.foo li {
display: block;
float: left;
width: 100px;
height: 100px;
border: 1px solid black;
margin: 2px;
}
You just subindex it with [:5]
indicating that you want (up to) the first 5 elements.
>>> [1,2,3,4,5,6,7,8][:5]
[1, 2, 3, 4, 5]
>>> [1,2,3][:5]
[1, 2, 3]
>>> x = [6,7,8,9,10,11,12]
>>> x[:5]
[6, 7, 8, 9, 10]
Also, putting the colon on the right of the number means count from the nth element onwards -- don't forget that lists are 0-based!
>>> x[5:]
[11, 12]
From where did you get the idea that you need to free(token)
and free(tk)
? You don't. strsep()
doesn't allocate memory, it only returns pointers inside the original string. Of course, those are not pointers allocated by malloc()
(or similar), so free()
ing them is undefined behavior. You only need to free(s)
when you are done with the entire string.
Also note that you don't need dynamic memory allocation at all in your example. You can avoid strdup()
and free()
altogether by simply writing char *s = p;
.
You can use System.exit()
for this purpose.
According to oracle's Java 8 documentation:
public static void exit(int status)
Terminates the currently running Java Virtual Machine. The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination.
This method calls the exit method in class Runtime. This method never returns normally.
The call
System.exit(n)
is effectively equivalent to the call:
Runtime.getRuntime().exit(n)
If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:
public function scopeLike($query, $field, $value){
return $query->where($field, 'LIKE', "%$value%");
}
So then you can use this method in such way:
User::like('name', 'Tomas')->get();
Hint: If you have more than one connection property then separate them with:
&
To give you somthing like:
url="jdbc:mysql://localhost/glyndwr?autoReconnect=true&allowMultiQueries=true"
I hope this helps some one.

Select the folder containing the package tree of these classes, right-click and choose "Mark Directory as -> Source Root"
Add line below at the beginning of your script ( or as second line):
# -*- coding: utf-8 -*-
That's definition of python source code encoding. More info in PEP 263.
you can use "__range" for example :
from datetime import datetime
start_date=datetime(2009, 12, 30)
end_end=datetime(2020,12,30)
Sample.objects.filter(date__range=[start_date,end_date])
Linked lists are preferable over arrays when:
you need constant-time insertions/deletions from the list (such as in real-time computing where time predictability is absolutely critical)
you don't know how many items will be in the list. With arrays, you may need to re-declare and copy memory if the array grows too big
you don't need random access to any elements
you want to be able to insert items in the middle of the list (such as a priority queue)
Arrays are preferable when:
you need indexed/random access to elements
you know the number of elements in the array ahead of time so that you can allocate the correct amount of memory for the array
you need speed when iterating through all the elements in sequence. You can use pointer math on the array to access each element, whereas you need to lookup the node based on the pointer for each element in linked list, which may result in page faults which may result in performance hits.
memory is a concern. Filled arrays take up less memory than linked lists. Each element in the array is just the data. Each linked list node requires the data as well as one (or more) pointers to the other elements in the linked list.
Array Lists (like those in .Net) give you the benefits of arrays, but dynamically allocate resources for you so that you don't need to worry too much about list size and you can delete items at any index without any effort or re-shuffling elements around. Performance-wise, arraylists are slower than raw arrays.
If you need wait until user is finished with typing use simple this:
$(document).on('change','#PageSize', function () {
//Do something after new value in #PageSize
});
Complete Example with ajax call - this working for my pager - count of item per list:
$(document).ready(function () {
$(document).on('change','#PageSize', function (e) {
e.preventDefault();
var page = 1;
var pagesize = $("#PageSize").val();
var q = $("#q").val();
$.ajax({
url: '@Url.Action("IndexAjax", "Materials", new { Area = "TenantManage" })',
data: { q: q, pagesize: pagesize, page: page },
type: 'post',
datatype: "json",
success: function (data) {
$('#tablecontainer').html(data);
// toastr.success('Pager has been changed', "Success!");
},
error: function (jqXHR, exception) {
ShowErrorMessage(jqXHR, exception);
}
});
});
});
I've found an answer to this problem :)
SET @update_id := 0;
UPDATE some_table SET column_name = 'value', id = (SELECT @update_id := id)
WHERE some_other_column = 'blah' LIMIT 1;
SELECT @update_id;
EDIT by aefxx
This technique can be further expanded to retrieve the ID of every row affected by an update statement:
SET @uids := null;
UPDATE footable
SET foo = 'bar'
WHERE fooid > 5
AND ( SELECT @uids := CONCAT_WS(',', fooid, @uids) );
SELECT @uids;
This will return a string with all the IDs concatenated by a comma.
You can actually use a JavaScriptConverter to accomplish this with the built-in JavaScriptSerializer. By converting your enum to a Uri you can encode it as a string.
I've described how to do this for dates but it can be used for enums as well. Custom DateTime JSON Format for .NET JavaScriptSerializer.
I'd use modulus and a loop.
int[] GetIntArray(int num)
{
List<int> listOfInts = new List<int>();
while(num > 0)
{
listOfInts.Add(num % 10);
num = num / 10;
}
listOfInts.Reverse();
return listOfInts.ToArray();
}
Store the value of the scroll as changes in HiddenField when around the PostBack retrieves the value and adds the scroll.
//jQuery
jQuery(document).ready(function () {
$(window).scrollTop($("#<%=hidScroll.ClientID %>").val());
$(window).scroll(function (event) {
$("#<%=hidScroll.ClientID %>").val($(window).scrollTop());
});
});
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
$(window).scrollTop($("#<%=hidScroll.ClientID %>").val());
$(window).scroll(function (event) {
$("#<%=hidScroll.ClientID %>").val($(window).scrollTop());
});
});
//Page Asp.Net
<asp:HiddenField ID="hidScroll" runat="server" Value="0" />
Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).
With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.
We'll take an example, a company table with a user table containing people from theses company
CREATE TABLE COMPANY (
company_id INT NOT NULL,
company_name VARCHAR(50),
PRIMARY KEY (company_id)
) ENGINE=INNODB;
CREATE TABLE USER (
user_id INT,
user_name VARCHAR(50),
company_id INT,
INDEX company_id_idx (company_id),
FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;
Let's look at the ON UPDATE clause:
And now on the ON DELETE side:
usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE
for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL
when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.
Edit
It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.
MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server
==> See below the last edit, things are moving on this domain
Triggers are not activated by foreign key actions.
And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.
But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.
as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).
Use $dec = $null
From the documentation:
$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.
PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.
I don't know what things were like in the alpha, but I'm using beta 12 right now and this works fine. If you have an array of objects, create a select like this:
<select [(ngModel)]="simpleValue"> // value is a string or number
<option *ngFor="let obj of objArray" [value]="obj.value">{{obj.name}}</option>
</select>
If you want to match on the actual object, I'd do it like this:
<select [(ngModel)]="objValue"> // value is an object
<option *ngFor="let obj of objArray" [ngValue]="obj">{{obj.name}}</option>
</select>
The ActionBar
usually exists along Fragments
so from the Activity
you can hide it
getActionBar().hide();
getActionBar().show();
and from the Fragment
you can do it
getActivity().getActionBar().hide();
getActivity().getActionBar().show();
Installing node_modules in container to different from project folder, and setting NODE_PATH to your node_modules folder helps me (u need to rebuild container).
I'm using docker-compose. My project file structure:
-/myproject
--docker-compose.yml
--nodejs/
----Dockerfile
docker-compose.yml:
version: '2'
services:
nodejs:
image: myproject/nodejs
build: ./nodejs/.
volumes:
- ./nodejs:/workdir
ports:
- "23005:3000"
command: npm run server
Dockerfile in nodejs folder:
FROM node:argon
RUN mkdir /workdir
COPY ./package.json /workdir/.
RUN mkdir /data
RUN ln -s /workdir/package.json /data/.
WORKDIR /data
RUN npm install
ENV NODE_PATH /data/node_modules/
WORKDIR /workdir
Use a function like this:
public static string FlattenException(Exception exception)
{
var stringBuilder = new StringBuilder();
while (exception != null)
{
stringBuilder.AppendLine(exception.Message);
stringBuilder.AppendLine(exception.StackTrace);
exception = exception.InnerException;
}
return stringBuilder.ToString();
}
Then you can call it like this:
try
{
// invoke code above
}
catch(MyCustomException we)
{
Debug.Writeline(FlattenException(we));
}
In JBoss Developer 4.0 and above (Eclipse-based), this is a tad easier. Just right-click on your file or folder that contains xml-based files, choose "Exclude Validation", then click "Yes" to confirm. Then right-click the same files/folder again and click on "Validate", which will remove the errors with a confirmation.
There are a lot of great answers here, but this is the approach I took for an Appium test where acting on a single element can result in going to different application states based on the user's settings. While it doesn't follow the conventions of OP's example, I hope it helps someone.
public <T extends MobilePage> T tapSignInButton(Class<T> type) throws NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {
//signInButton.click();
return type.getConstructor(AppiumDriver.class).newInstance(appiumDriver);
}
If you don't want to throw the errors you can catch them like so:
public <T extends MobilePage> T tapSignInButton(Class<T> type) {
// signInButton.click();
T returnValue = null;
try {
returnValue = type.getConstructor(AppiumDriver.class).newInstance(appiumDriver);
} catch (Exception e) {
e.printStackTrace();
}
return returnValue;
}
In my case, just using flex-shrink: 0
didn't work. But adding flex-grow: 1
to it worked.
.item {
flex-shrink: 0;
flex-grow: 1;
}
Given your updated question, these are the simplest forms:
If ProductID
is unique you want
SELECT COUNT(*) FROM Products WHERE ProductID IN (1, 10, 100)
and then check that result against 3
, the number of products you're querying (this last part can be done in SQL, but it may be easier to do it in C# unless you're doing even more in SQL).
If ProductID
is not unique it is
SELECT COUNT(DISTINCT ProductID) FROM Products WHERE ProductID IN (1, 10, 100)
When the question was thought to require returning rows when all ProductIds
are present and none otherwise:
SELECT ProductId FROM Products WHERE ProductID IN (1, 10, 100) AND ((SELECT COUNT(*) FROM Products WHERE ProductID IN (1, 10, 100))=3)
or
SELECT ProductId FROM Products WHERE ProductID IN (1, 10, 100) AND ((SELECT COUNT(DISTINCT ProductID) FROM Products WHERE ProductID IN (1, 10, 100))=3)
if you actually intend to do something with the results. Otherwise the simple SELECT 1 WHERE (SELECT ...)=3
will do as other answers have stated or implied.
I need the exact same feature described in this question. Here is my solution and source code: https://github.com/laoyang/android-dynamic-views. And you can see the video demo in action here: http://www.youtube.com/watch?v=4HeqyG6FDhQ
Basically you'll two xml layout files:
TextEdit
, a Spinner
and an ImageButton
for deletion. In the Java code, you'll add and remove row views into the container dynamically, using inflate, addView, removeView, etc. There are some visibility control for better UX in the stock Android app. You need add a TextWatcher for the EditText view in each row: when the text is empty you need to hide the Add new button and the delete button. In my code, I wrote a void inflateEditRow(String)
helper function for all the logic.
android:animateLayoutChanges="true"
in xml to enable animationThe Java code of the main activity ( This explains all the logic, but quite a few properties are set in xml layout files, please refer to the Github source for complete solution):
public class MainActivity extends Activity {
// Parent view for all rows and the add button.
private LinearLayout mContainerView;
// The "Add new" button
private Button mAddButton;
// There always should be only one empty row, other empty rows will
// be removed.
private View mExclusiveEmptyView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.row_container);
mContainerView = (LinearLayout) findViewById(R.id.parentView);
mAddButton = (Button) findViewById(R.id.btnAddNewItem);
// Add some examples
inflateEditRow("Xiaochao");
inflateEditRow("Yang");
}
// onClick handler for the "Add new" button;
public void onAddNewClicked(View v) {
// Inflate a new row and hide the button self.
inflateEditRow(null);
v.setVisibility(View.GONE);
}
// onClick handler for the "X" button of each row
public void onDeleteClicked(View v) {
// remove the row by calling the getParent on button
mContainerView.removeView((View) v.getParent());
}
// Helper for inflating a row
private void inflateEditRow(String name) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.row, null);
final ImageButton deleteButton = (ImageButton) rowView
.findViewById(R.id.buttonDelete);
final EditText editText = (EditText) rowView
.findViewById(R.id.editText);
if (name != null && !name.isEmpty()) {
editText.setText(name);
} else {
mExclusiveEmptyView = rowView;
deleteButton.setVisibility(View.INVISIBLE);
}
// A TextWatcher to control the visibility of the "Add new" button and
// handle the exclusive empty view.
editText.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable s) {
// Some visibility logic control here:
if (s.toString().isEmpty()) {
mAddButton.setVisibility(View.GONE);
deleteButton.setVisibility(View.INVISIBLE);
if (mExclusiveEmptyView != null
&& mExclusiveEmptyView != rowView) {
mContainerView.removeView(mExclusiveEmptyView);
}
mExclusiveEmptyView = rowView;
} else {
if (mExclusiveEmptyView == rowView) {
mExclusiveEmptyView = null;
}
mAddButton.setVisibility(View.VISIBLE);
deleteButton.setVisibility(View.VISIBLE);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
});
// Inflate at the end of all rows but before the "Add new" button
mContainerView.addView(rowView, mContainerView.getChildCount() - 1);
}

It turns out that OpenSSL is compiled and enabled in php 5.3 of XAMPP 1.7.2 and so no longer requires a separate extension dll.
However, you STILL need to enable it in your PHP.ini file the line extension=php_openssl.dll
The gritty terminal was written to use Jsch, but with better handling and vt102 emulation. You can take a look at the code there. We use it and it works just fine.
This works for me
var options = $(dropdown).find('option');
var targetOption = $(options).filter(
function () { return $(this).html() == value; });
console.log($(targetOption).val());
Thanks for all the posts.

In case you want to pass in a block, say, for a glyphicon button, as in the following:
<%= link_to my_url, class: "stuff" do %>
<i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>
Then passing querystrings params could be accomplished through:
<%= link_to url_for(params.merge(my_params: "value")), class: "stuff" do %>
<i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>
window.opener

[^0-9][+-]?[0-9]{1,10}[^0-9]
In words: Optional + or - followed by a digit, repeated one up to ten times. Note that most libraries have a shortcut for a digit: \d

Those steps should be able to be shortened down to:
hg pull
hg update -r MY_BRANCH -C
The -C
flag tells the update command to discard all local changes before updating.
However, this might still leave untracked files in your repository. It sounds like you want to get rid of those as well, so I would use the purge
extension for that:
hg pull
hg update -r MY_BRANCH -C
hg purge
In any case, there is no single one command you can ask Mercurial to perform that will do everything you want here, except if you change the process to that "full clone" method that you say you can't do.
import * as fs from 'fs';
import * as path from 'path';
fs.readFile(path.join(__dirname, "filename.txt"), (err, data) => {
if (err) throw err;
console.log(data);
})
EDIT:
consider the project structure:
../readfile/
+-- filename.txt
+-- src
+-- index.js
+-- index.ts
consider the index.ts
:
import * as fs from 'fs';
import * as path from 'path';
function lookFilesInDirectory(path_directory) {
fs.stat(path_directory, (err, stat) => {
if (!err) {
if (stat.isDirectory()) {
console.log(path_directory)
fs.readdirSync(path_directory).forEach(file => {
console.log(`\t${file}`);
});
console.log();
}
}
});
}
let path_view = './';
lookFilesInDirectory(path_view);
lookFilesInDirectory(path.join(__dirname, path_view));
if you have in the readfile folder and run tsc src/index.ts && node src/index.js
, the output will be:
./
filename.txt
src
/home/andrei/scripts/readfile/src/
index.js
index.ts
that is, it depends on where you run the node.
the __dirname is directory name of the current module.
When you create a flex container various default flex rules come into play.
Two of these default rules are flex-direction: row
and align-items: stretch
. This means that flex items will automatically align in a single row, and each item will fill the height of the container.
If you don't want flex items to stretch – i.e., like you wrote:
make its height the minimum required for holding its content
... then simply override the default with align-items: flex-start
.
#a {_x000D_
display: flex;_x000D_
align-items: flex-start; /* NEW */_x000D_
}_x000D_
#a > div {_x000D_
background-color: red;_x000D_
padding: 5px;_x000D_
margin: 2px;_x000D_
}_x000D_
#b {_x000D_
height: auto;_x000D_
}
_x000D_
<div id="a">_x000D_
<div id="b">left</div>_x000D_
<div>_x000D_
right<br>right<br>right<br>right<br>right<br>_x000D_
</div>_x000D_
</div>
_x000D_
Here's an illustration from the flexbox spec that highlights the five values for align-items
and how they position flex items within the container. As mentioned before, stretch
is the default value.

The equivalent C code looks like this:
#include <stdio.h>
#include <string.h>
// This code outputs: h is in "This is my test string"
int main(int argc, char* argv[])
{
const char *invalid_characters = "hz";
char *mystring = "This is my test string";
char *c = mystring;
while (*c)
{
if (strchr(invalid_characters, *c))
{
printf("%c is in \"%s\"\n", *c, mystring);
}
c++;
}
return 0;
}
Note that invalid_characters is a C string, ie. a null-terminated char
array.

Are you asking in php or javascript.
If it is in php, give the name of that and use the post or get method, after that you can use the option of isset or that particular button name is checked to that value.
If it is in js, use getElementById for that
A solution using prototypes is only possible when your objects are alike:
function Cons(g) { this.good = g; }
Cons.prototype.bad = "something common";
var array = [new Cons("something 1"), new Cons("something 2"), …];
But then it's simple (and O(1)
):
delete Cons.prototype.bad;
There are few properties to set to make a Hive table support ACID properties and to insert the values into tables as like in SQL .
Conditions to create a ACID table in Hive.
Properties to set to create ACID table:
set hive.support.concurrency =true;
set hive.enforce.bucketing =true;
set hive.exec.dynamic.partition.mode =nonstrict
set hive.compactor.initiator.on = true;
set hive.compactor.worker.threads= 1;
set hive.txn.manager = org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
set the property hive.in.test to true in hive.site.xml
After setting all these properties , the table should be created with tblproperty 'transactional' ='true'. The table should be bucketed and saved as orc
CREATE TABLE table_name (col1 int,col2 string, col3 int) CLUSTERED BY col1 INTO 4
BUCKETS STORED AS orc tblproperties('transactional' ='true');
Now its possible to inserte values into the table like SQL query.
INSERT INTO TABLE table_name VALUES (1,'a',100),(2,'b',200),(3,'c',300);

The following worked for me against a SQL Azure backend (using SQL Server Management Studio), so YMMV, but, if it works for you, it's waaaaay simpler than the other solutions.
ALTER TABLE MyTable
DROP CONSTRAINT FK_MyColumn
CONSTRAINT DK_MyColumn
-- etc...
COLUMN MyColumn
GO
A way better solution is to just use the excelent compatibility script from Anthony Ferrara:
https://github.com/ircmaxell/password_compat
Please, and also, when checking the password, always add a way (preferibly async, so it doesn't impact the check process for timming attacks) to update the hash if needed.
If you are using Java 7 You can use Objects.requireNotNull(object[, optionalMessage]);
- to check if the parameter is null
. To check if each element is not null just use
if(null != books[i]){/*do stuff*/}
Example:
public static double calculateInventoryTotal(Book[] books){
Objects.requireNotNull(books, "Books must not be null");
double total = 0;
for (int i = 0; i < books.length; i++){
if(null != book[i]){
total += books[i].getPrice();
}
}
return total;
}
Use the --force
(-f
) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.
For example:
mysql -u userName -p -f -D dbName < script.sql
function hasNoDuplicates(arr) {
return arr.every(num => arr.indexOf(num) === arr.lastIndexOf(num));
}
hasNoDuplicates
accepts an array and returns true
if there are no duplicate values. If there are any duplicates, the function returns false
.
try this
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/linuxbrew/go/install)"
It is unnecessary. You can use an ORDER BY
and just change the sort to DESC
to get the same effect.
You can describe your css selection like cascading style sheet dows:
protected override void When()
{
SUT.Browser.FindElements(By.CssSelector("#carousel > a.tiny.button"))
}
HAVING: is used to check conditions after the aggregation takes place.
WHERE: is used to check conditions before the aggregation takes place.
This code:
select City, CNT=Count(1)
From Address
Where State = 'MA'
Group By City
Gives you a table of all cities in MA and the number of addresses in each city.
This code:
select City, CNT=Count(1)
From Address
Where State = 'MA'
Group By City
Having Count(1)>5
Gives you a table of cities in MA with more than 5 addresses and the number of addresses in each city.
Yes. The sequence doesn't have the 54th item.
Adam's chromeFix solution with Paul Alexander's pure-CSS modification solved the problem in Chrome, but not in Safari. A couple additional tweaks solved the problem in Safari, too: width: 100%
and z-index:-1
(or some other appropriate negative value that puts this element behind all the other elements on the page).
The CSS:
body:after {display:block; position:absolute; width:100%; height:100%; top:0px; left:0px; z-index:-1; content: "";}
Strange answers here! You can insert strings into other strings easily with sprintf [link to documentation]. The function is extremely powerful and can handle multiple elements and other data types too.
$color = 'green';
sprintf('I like %s apples.', $color);
gives you the string
I like green apples.

app.filter('dateUTC', function ($filter) {
return function (input, format) {
if (!angular.isDefined(format)) {
format = 'dd/MM/yyyy';
}
var date = new Date(input);
return $filter('date')(date.toISOString().slice(0, 23), format);
};
});
Let's not forget math.hypot:
dist = math.hypot(x2-x1, y2-y1)
Here's hypot as part of a snippet to compute the length of a path defined by a list of (x, y) tuples:
from math import hypot
pts = [
(10,10),
(10,11),
(20,11),
(20,10),
(10,10),
]
# Py2 syntax - no longer allowed in Py3
# ptdiff = lambda (p1,p2): (p1[0]-p2[0], p1[1]-p2[1])
ptdiff = lambda p1, p2: (p1[0]-p2[0], p1[1]-p2[1])
diffs = (ptdiff(p1, p2) for p1, p2 in zip (pts, pts[1:]))
path = sum(hypot(*d) for d in diffs)
print(path)
$(document).mousedown(function(e) {
if( e.button == 2 ) {
e.preventDefault();
return false;
}
});
Interestingly no one answers the question, OP isn't using a strongly typed int[]
but an Array
.
You have to cast the Array
to what it actually is, an int[]
, then you can use ToList
:
List<int> intList = ((int[])ints).ToList();
Note that Enumerable.ToList
calls the list constructor that first checks if the argument can be casted to ICollection<T>
(which an array implements), then it will use the more efficient ICollection<T>.CopyTo
method instead of enumerating the sequence.
var fs = require('fs');
function base64Encode(file) {
var body = fs.readFileSync(file);
return body.toString('base64');
}
var base64String = base64Encode('test.jpg');
console.log(base64String);
Set in RecyclerView
initialization
recyclerView.setLayoutManager(new GridLayoutManager(this, 4));
I'm not sure it's good way to check it. What about case when user uses button "clear data" from settings? SharedPreferences will be cleared and you catch "first run" again. And it's a problem. I guess it's better idea to use InstallReferrerReceiver.
I hate to post my own answer, but some answers recently have ignored the solution I posted in my own question, suggesting approaches that are nothing short of foolhardy.
In short - you do not need to edit any Windows user account privileges at all. Doing so only introduces risk. The process is entirely managed in IIS using inherited privileges.
Right-click the domain when it appears under the Sites list, and choose Edit Permissions
Under the Security tab, you will see MACHINE_NAME\IIS_IUSRS
is listed. This means that IIS automatically has read-only permission on the directory (e.g. to run ASP.Net in the site). You do not need to edit this entry.
Click the Edit button, then Add...
In the text box, type IIS AppPool\MyApplicationPoolName
, substituting MyApplicationPoolName
with your domain name or whatever application pool is accessing your site, e.g. IIS AppPool\mydomain.com
Press the Check Names button. The text you typed will transform (notice the underline):
Press OK to add the user
With the new user (your domain) selected, now you can safely provide any Modify or Write permissions
If you want want the end Collection
to be in the form of Set
and if you want to define your own natural order
rather than that of TreeSet
then -
1. Convert the HashSet
into List
2. Custom sort the List
using Comparator
3. Convert back the List
into LinkedHashSet
to maintain order
4. Display the LinkedHashSet
Sample program -
package demo31;
import java.util.Collections;
import java.util.Comparator;
import java.util.HashSet;
import java.util.LinkedHashSet;
import java.util.LinkedList;
import java.util.List;
import java.util.Set;
public class App26 {
public static void main(String[] args) {
Set<String> set = new HashSet<>();
addElements(set);
List<String> list = new LinkedList<>();
list = convertToList(set);
Collections.sort(list, new Comparator<String>() {
@Override
public int compare(String s1, String s2) {
int flag = s2.length() - s1.length();
if(flag != 0) {
return flag;
} else {
return -s1.compareTo(s2);
}
}
});
Set<String> set2 = new LinkedHashSet<>();
set2 = convertToSet(list);
displayElements(set2);
}
public static void addElements(Set<String> set) {
set.add("Hippopotamus");
set.add("Rhinocerous");
set.add("Zebra");
set.add("Tiger");
set.add("Giraffe");
set.add("Cheetah");
set.add("Wolf");
set.add("Fox");
set.add("Dog");
set.add("Cat");
}
public static List<String> convertToList(Set<String> set) {
List<String> list = new LinkedList<>();
for(String element: set) {
list.add(element);
}
return list;
}
public static Set<String> convertToSet(List<String> list) {
Set<String> set = new LinkedHashSet<>();
for(String element: list) {
set.add(element);
}
return set;
}
public static void displayElements(Set<String> set) {
System.out.println(set);
}
}
Output -
[Hippopotamus, Rhinocerous, Giraffe, Cheetah, Zebra, Tiger, Wolf, Fox, Dog, Cat]
Here the collection has been sorted as -
First - Descending order of String
length
Second - Descending order of String
alphabetical hierarchy
You can use exit method to quit an ios app :
exit(0);
You should say same alert message and ask him to quit
Another way is by using [[NSThread mainThread] exit]
However you should not do this way
According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.
You can add manually in the manifest file within manifest tag by:
<uses-permission android:name="android.permission.CAMERA"/>
This permission is required to be able to access the camera device.
I stumbled on this thread while trying to find a Windows alternative for getpid()
(defined in unistd.h
). It turns out that including process.h
does the trick. Maybe this helps people who find this thread in the future.
Allocate memory to hold chars.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct PString {
char *chars;
int (*length)(PString *self);
} PString;
int length(PString *self) {
return strlen(self->chars);
}
PString *initializeString(int n) {
PString *str = malloc(sizeof(PString));
str->chars = malloc(sizeof(char) * n);
str->length = length;
str->chars[0] = '\0'; //add a null terminator in case the string is used before any other initialization.
return str;
}
int main() {
PString *p = initializeString(30);
strcpy(p->chars, "Hello");
printf("\n%d", p->length(p));
return 0;
}
$(selector).attr('checked') !== undefined
This returns true
if the input is checked and false
if it is not.
removePeople(e){
var array = this.state.people;
var index = array.indexOf(e.target.value); // Let's say it's Bob.
array.splice(index,1);
}
Redfer doc for more info
A one liner:
perl -pi.back -e 's/<PREF>/ABCD/g;' inputfile
Hide the file input. Create a new input to capture a click event and forward it to the hidden input:
<input type="button" id="loadFileXml" value="loadXml" onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file"/>
.xlsx

(Hardware: Core2Duo 2.3 GHz, 4 GB RAM, 5.400 rpm SATA II HD; Windows 7, under somewhat heavy load from other processes.)
Beside this, there should be no differences. More precisely,
both formats support exactly the same feature set
cites this blog post from 2006-08-29. So maybe the info that .xlsb
does not support Ribbon code is newer than the upper citation, but I figure that forum source of yours is just wrong. When cracking open the binary file, it seems to condensedly mimic the OOXML file structure 1-to-1: Blog article from 2006-08-07
if no such option exists, then maybe there is a nice idiomatic one-liner for doing that ? like, using for...of, or similar ?
Indeed, there are several ways to convert a Set to an Array:
using Array.from
let array = Array.from(mySet);
Simply spreading
the Set out in an array
let array = [...mySet];
The old fashion way, iterating and pushing to a new array (Sets do have forEach
)
let array = [];
mySet.forEach(v => array.push(v));
Previously, using the non-standard, and now deprecated array comprehension syntax:
let array = [v for (v of mySet)];
The way I would do it is to leave the __ init__.py files empty, and do:
import lib.mod1.mod11
lib.mod1.mod11.mod12()
or
from lib.mod1.mod11 import mod12
mod12()
You may find that the mod1 dir is unnecessary, just have mod12.py in lib.
Got a better approach to implement the animating FAB menu without using any library or to write huge xml code for animations. hope this will help in future for someone who needs a simple way to implement this.
Just using animate().translationY()
function, you can animate any view up or down just I did in my below code, check complete code in github. In case you are looking for the same code in kotlin, you can checkout the kotlin code repo Animating FAB Menu.
first define all your FAB at same place so they overlap each other, remember on top the FAB should be that you want to click and to show other. eg:
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab3"
android:layout_width="@dimen/standard_45"
android:layout_height="@dimen/standard_45"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/standard_21"
app:srcCompat="@android:drawable/ic_btn_speak_now" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab2"
android:layout_width="@dimen/standard_45"
android:layout_height="@dimen/standard_45"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/standard_21"
app:srcCompat="@android:drawable/ic_menu_camera" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab1"
android:layout_width="@dimen/standard_45"
android:layout_height="@dimen/standard_45"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/standard_21"
app:srcCompat="@android:drawable/ic_dialog_map" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
app:srcCompat="@android:drawable/ic_dialog_email" />
Now in your java class just define all your FAB and perform the click like shown below:
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab1 = (FloatingActionButton) findViewById(R.id.fab1);
fab2 = (FloatingActionButton) findViewById(R.id.fab2);
fab3 = (FloatingActionButton) findViewById(R.id.fab3);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(!isFABOpen){
showFABMenu();
}else{
closeFABMenu();
}
}
});
Use the animation().translationY()
to animate your FAB,I prefer you to use the attribute of this method in DP since only using an int will effect the display compatibility with higher resolution or lower resolution. as shown below:
private void showFABMenu(){
isFABOpen=true;
fab1.animate().translationY(-getResources().getDimension(R.dimen.standard_55));
fab2.animate().translationY(-getResources().getDimension(R.dimen.standard_105));
fab3.animate().translationY(-getResources().getDimension(R.dimen.standard_155));
}
private void closeFABMenu(){
isFABOpen=false;
fab1.animate().translationY(0);
fab2.animate().translationY(0);
fab3.animate().translationY(0);
}
Now define the above mentioned dimension inside res->values->dimens.xml as shown below:
<dimen name="standard_55">55dp</dimen>
<dimen name="standard_105">105dp</dimen>
<dimen name="standard_155">155dp</dimen>
That's all hope this solution will help the people in future, who are searching for simple solution.
EDITED
If you want to add label over the FAB then simply take a horizontal LinearLayout and put the FAB with textview as label, and animate the layouts if find any issue doing this, you can check my sample code in github, I have handelled all backward compatibility issues in that sample code. check my sample code for FABMenu in Github
to close the FAB on Backpress, override onBackPress() as showen below:
@Override
public void onBackPressed() {
if(!isFABOpen){
this.super.onBackPressed();
}else{
closeFABMenu();
}
}
The Screenshot have the title as well with the FAB,because I take it from my sample app present ingithub
this is your first Activity1.
public class Activity1 extends Activity{
private int mRequestCode = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(this, Activity2.class);
startActivityForResult(intent, mRequestCode);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == mRequestCode && resultCode == RESULT_OK){
String editTextString = data.getStringExtra("editText");
}
}
}
From here you are starting your Activity2.class by using startActivityForResult(mRequestCode, Activity2.class);
Now this is your second Activity, name is Activity2
public class Activity2 extends Activity {
private EditText mEditText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//mEditText = (EditText)findViewById(R.id.edit_text);
Intent intent = new Intent();
intent.putExtra("editText", mEditText.getText().toString());
setResult(RESULT_OK, intent);
}
}
Now when you done with your second Activity then you call setResult() method, from onBackPress() or from any button click when your Activity2 will destroy then your Activity1's call back method onActivityResult() will call from there you can get your data from intent..
Hope it will help to you...:)
Looks like you want to use java.lang.Class.getResourceAsStream(String)
, see
https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getResourceAsStream-java.lang.String-
It is a new signing mechanism introduced in Android 7.0, with additional features designed to make the APK signature more secure.
It is not mandatory. You should check BOTH of those checkboxes if possible, but if the new V2 signing mechanism gives you problems, you can omit it.
So you can just leave V2 unchecked if you encounter problems, but should have it checked if possible.
UPDATED: This is now mandatory when targeting Android 11.
Rarely, a hardened HTTP server is configured to give no server information or misleading server information. In those scenarios if the server has PHP enabled you can add:
<?php phpinfo(); ?>
in a file and browse to it and look for the
_SERVER["SERVER_SOFTWARE"]
entry. This is susceptible to the same hardening lack of information/misleading though I would imagine that it's not altered often, because this method first requires access to the machine to create the PHP file.
A QueryString is, by definition, in the URL. You can access the URL of the request using req.URL
(doc). The URL object has a Query()
method (doc) that returns a Values
type, which is simply a map[string][]string
of the QueryString parameters.
If what you're looking for is the POST data as submitted by an HTML form, then this is (usually) a key-value pair in the request body. You're correct in your answer that you can call ParseForm()
and then use req.Form
field to get the map of key-value pairs, but you can also call FormValue(key)
to get the value of a specific key. This calls ParseForm()
if required, and gets values regardless of how they were sent (i.e. in query string or in the request body).
I was looking for an answer that restricted input to only alphanumeric characters, but still allowed for the use of control characters (e.g., backspace, delete, tab) and copy+paste. None of the provided answers that I tried satisfied all of these requirements, so I came up with the following using the input
event.
$('input').on('input', function() {
$(this).val($(this).val().replace(/[^a-z0-9]/gi, ''));
});
Edit:
As rinogo pointed out in the comments, the above code snippet forces the cursor to the end of the input when typing in the middle of the input text. I believe the code snippet below solves this problem.
$('input').on('input', function() {
var c = this.selectionStart,
r = /[^a-z0-9]/gi,
v = $(this).val();
if(r.test(v)) {
$(this).val(v.replace(r, ''));
c--;
}
this.setSelectionRange(c, c);
});
use this
byte[] myByte= System.Text.ASCIIEncoding.Default.GetBytes(myString);
Because of double print function. I suggest you to use return
instead of print
inside the function definition.
def lyrics():
return "The very first line"
print(lyrics())
OR
def lyrics():
print("The very first line")
lyrics()
I would use the SplFileObject class...
$file = new SplFileObject("filename");
if (!$file->eof()) {
$file->seek($lineNumber);
$contents = $file->current(); // $contents would hold the data from line x
}
My solution was simply to reload a saved GOOD (backup) copy of my settings (made a year ago). Worth trying before resetting everything to blank. My VS2010 would take 60 seconds to start debugging and approx. 3 minutes to stop debugging. I saved the corrupted settings and to my surprise they were over 3MB instead of 260Kb. I loaded the good backup copy and everything is great again :-)
Add to your .gitconfig file next code:
[color]
ui = auto
[color "branch"]
current = yellow reverse
local = yellow
remote = green
[color "diff"]
meta = yellow bold
frag = magenta bold
old = red bold
new = green bold
[color "status"]
added = yellow
changed = green
untracked = cyan
I think a really simple answer might be useful here:
return
makes the value (a variable, often) available for use by the caller (for example, to be stored by a function that the function using return
is within). Without return
, your value or variable wouldn't be available for the caller to store/re-use.
print
prints to the screen, but does not make the value or variable available for use by the caller.
(Fully admitting that the more thorough answers are more accurate.)
With less you can set it up like this;
.table tbody tr {
&.error > td { background-color: red !important; }
&.error:hover > td { background-color: yellow !important; }
&.success > td { background-color: green !important; }
&.success:hover > td { background-color: yellow !important; }
...
}
That did the trick for me.
Use Java Decompiler to turn the jar file into source code file, and then use WinMerge to perform comparison.
You should consult the copyright holder of the source code, to see whether it is OK to do so.
The trunc()
function truncates a date to the specified time period; so trunc(sysdate,'mm')
would return the beginning of the current month. You can then use the add_months()
function to get the beginning of the previous month, something like this:
select count(distinct switch_id)
from [email protected]
where dealer_name = 'XXXX'
and creation_date >= add_months(trunc(sysdate,'mm'),-1)
and creation_date < trunc(sysdate, 'mm')
As a little side not you're not explicitly converting to a date in your original query. Always do this, either using a date literal, e.g. DATE 2012-08-31
, or the to_date()
function, for example to_date('2012-08-31','YYYY-MM-DD')
. If you don't then you are bound to get this wrong at some point.
You would not use sysdate - 15
as this would provide the date 15 days before the current date, which does not seem to be what you are after. It would also include a time component as you are not using trunc()
.
Just as a little demonstration of what trunc(<date>,'mm')
does:
select sysdate
, case when trunc(sysdate,'mm') > to_date('20120901 00:00:00','yyyymmdd hh24:mi:ss')
then 1 end as gt
, case when trunc(sysdate,'mm') < to_date('20120901 00:00:00','yyyymmdd hh24:mi:ss')
then 1 end as lt
, case when trunc(sysdate,'mm') = to_date('20120901 00:00:00','yyyymmdd hh24:mi:ss')
then 1 end as eq
from dual
;

</paths>
Of course you can use the StringTokenizer
class to split the String with '.' or '/', and check if the last word is "work".
As @DSM points out, you can do this more directly using the vectorised string methods:
df['Date'].str[-4:].astype(int)
Or using extract (assuming there is only one set of digits of length 4 somewhere in each string):
df['Date'].str.extract('(?P<year>\d{4})').astype(int)
An alternative slightly more flexible way, might be to use apply
(or equivalently map
) to do this:
df['Date'] = df['Date'].apply(lambda x: int(str(x)[-4:]))
# converts the last 4 characters of the string to an integer
The lambda function, is taking the input from the Date
and converting it to a year.
You could (and perhaps should) write this more verbosely as:
def convert_to_year(date_in_some_format):
date_as_string = str(date_in_some_format) # cast to string
year_as_string = date_in_some_format[-4:] # last four characters
return int(year_as_string)
df['Date'] = df['Date'].apply(convert_to_year)
Perhaps 'Year' is a better name for this column...
first of all;
a Fragment
must be inside a FragmentActivity
, that's the first rule,
a FragmentActivity
is quite similar to a standart Activity
that you already know, besides having some Fragment oriented methods
second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView
, where you inflate your layout, think of it as the setContentLayout
here is an example:
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { mView = inflater.inflate(R.layout.fragment_layout, container, false); return mView; }
and continu your work based on that mView, so to find a View
by id, call mView.findViewById(..);
for the FragmentActivity
part:
the xml part "must" have a FrameLayout
in order to inflate a fragment in it
<FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout>
as for the inflation part
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();
begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site
Nothing worked for me but:
componentDidMount(){
$( document ).ready(function() {
window.scrollTo(0,0);
});
}
At least write the code without the bushy tree:
#!/bin/bash
PASSED=$1
if [ -d "${PASSED}" ]
then echo "${PASSED} is a directory";
elif [ -f "${PASSED}" ]
then echo "${PASSED} is a file";
else echo "${PASSED} is not valid";
exit 1
fi
When I put that into a file "xx.sh" and create a file "xx sh", and run it, I get:
$ cp /dev/null "xx sh"
$ for file in . xx*; do sh "$file"; done
. is a directory
xx sh is a file
xx.sh is a file
$
Given that you are having problems, you should debug the script by adding:
ls -l "${PASSED}"
This will show you what ls
thinks about the names you pass the script.
I like adding functions to jQuery so this function would help:
jQuery.fn.center = function () {
this.css("position","absolute");
this.css("top", Math.max(0, (($(window).height() - $(this).outerHeight()) / 2) +
$(window).scrollTop()) + "px");
this.css("left", Math.max(0, (($(window).width() - $(this).outerWidth()) / 2) +
$(window).scrollLeft()) + "px");
return this;
}
Now we can just write:
$(element).center();
Demo: Fiddle (with added parameter)
Just an update.
If the ticked answer is working fine for you but it shows nothing when the search text is empty. Here is the solution:

FilterResults results = new FilterResults();
if(constraint.length() == 0)
{

}else {
final List<String> list = originalData;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
}
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}

Just finished understanding Peek and Keep and had same confusion initially. The confusion arises becauses TempData behaves differently under different condition. You can watch this video which explains the Keep and Peek with demonstration https://www.facebook.com/video.php?v=689393794478113
Tempdata helps to preserve values for a single request and CAN ALSO preserve values for the next request depending on 4 conditions”.
If we understand these 4 points you would see more clarity.Below is a diagram with all 4 conditions, read the third and fourth point which talks about Peek and Keep.
Condition 1 (Not read):- If you set a “TempData” inside your action and if you do not read it in your view then “TempData” will be persisted for the next request.
Condition 2 ( Normal Read) :- If you read the “TempData” normally like the below code it will not persist for the next request.
string str = TempData["MyData"];
Even if you are displaying it’s a normal read like the code below.
@TempData["MyData"];
Condition 3 (Read and Keep) :- If you read the “TempData” and call the “Keep” method it will be persisted.
@TempData["MyData"];
TempData.Keep("MyData");
Condition 4 ( Peek and Read) :- If you read “TempData” by using the “Peek” method it will persist for the next request.
string str = TempData.Peek("Td").ToString();
Reference :- http://www.codeproject.com/Articles/818493/MVC-Tempdata-Peek-and-Keep-confusion
I think the best first approach is to make sure to turn on detailed error messages via your web.config file, like this:
<configuration>
<system.webServer>
<httpErrors errorMode="Detailed"></httpErrors>
</system.webServer>
</configuration>
After doing this, you should get a more detailed error message from the server.
In my particular case, the more detailed error pointed out that my <defaultDocument>
section of the web.config file was not allowed at the folder level where I'd placed my web.config. It said
This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false". "
I benchmarked all the other answers on an iPhone 4S and iPad 3 (release builds). CACurrentMediaTime
has the least overhead by a small margin. timeIntervalSince1970
is far slower than the others, probably due to NSDate
instantiation overhead, though it may not matter for many use cases.
I'd recommend CACurrentMediaTime
if you want the least overhead and don't mind adding the Quartz Framework dependency. Or gettimeofday
if portability is a priority for you.
iPhone 4S
CACurrentMediaTime: 1.33 µs/call
gettimeofday: 1.38 µs/call
[NSDate timeIntervalSinceReferenceDate]: 1.45 µs/call
CFAbsoluteTimeGetCurrent: 1.48 µs/call
[[NSDate date] timeIntervalSince1970]: 4.93 µs/call
iPad 3
CACurrentMediaTime: 1.25 µs/call
gettimeofday: 1.33 µs/call
CFAbsoluteTimeGetCurrent: 1.34 µs/call
[NSDate timeIntervalSinceReferenceDate]: 1.37 µs/call
[[NSDate date] timeIntervalSince1970]: 3.47 µs/call
If you want to re-filter the json data you can use following method. Given example is getting all document data from couchdb.
{
Gson gson = new Gson();
String resultJson = restTemplate.getForObject(url+"_all_docs?include_docs=true", String.class);
JSONObject object = (JSONObject) new JSONParser().parse(resultJson);
JSONArray rowdata = (JSONArray) object.get("rows");
List<Object>list=new ArrayList<Object>();
for(int i=0;i<rowdata.size();i++) {
JSONObject index = (JSONObject) rowdata.get(i);
JSONObject data = (JSONObject) index.get("doc");
list.add(data);
}
// convert your list to json
String devicelist = gson.toJson(list);
return devicelist;
}
Here's how I do file upload in react using axios
import React from 'react'
import axios, { post } from 'axios';
class SimpleReactFileUpload extends React.Component {
constructor(props) {
super(props);
this.state ={
file:null
}
this.onFormSubmit = this.onFormSubmit.bind(this)
this.onChange = this.onChange.bind(this)
this.fileUpload = this.fileUpload.bind(this)
}
onFormSubmit(e){
e.preventDefault() // Stop form submit
this.fileUpload(this.state.file).then((response)=>{
console.log(response.data);
})
}
onChange(e) {
this.setState({file:e.target.files[0]})
}
fileUpload(file){
const url = 'http://example.com/file-upload';
const formData = new FormData();
formData.append('file',file)
const config = {
headers: {
'content-type': 'multipart/form-data'
}
}
return post(url, formData,config)
}
render() {
return (
<form onSubmit={this.onFormSubmit}>
<h1>File Upload</h1>
<input type="file" onChange={this.onChange} />
<button type="submit">Upload</button>
</form>
)
}
}
export default SimpleReactFileUpload
You can also use numpy.subtract
It has the advantage over the difference operator, -
, that you do not have to transform the sequences (list or tuples) into a numpy arrays — you save the two commands:
array1 = np.array([1.1, 2.2, 3.3])
array2 = np.array([1, 2, 3])
Example: (Python 3.5)
import numpy as np
result = np.subtract([1.1, 2.2, 3.3], [1, 2, 3])
print ('the difference =', result)
which gives you
the difference = [ 0.1 0.2 0.3]
Remember, however, that if you try to subtract sequences (lists or tuples) with the -
operator you will get an error. In this case, you need the above commands to transform the sequences in numpy arrays
Wrong Code:
print([1.1, 2.2, 3.3] - [1, 2, 3])
$('someSelectorForTheElement').attr('name');

First, let me explain what a mem-initializer-list is. A mem-initializer-list is a comma-separated list of mem-initializers, where each mem-initializer is a member name followed by (
, followed by an expression-list, followed by a )
. The expression-list is how the member is constructed. For example, in
static const char s_str[] = "bodacydo";
class Example
{
private:
int *ptr;
string name;
string *pname;
string &rname;
const string &crname;
int age;
public:
Example()
: name(s_str, s_str + 8), rname(name), crname(name), age(-4)
{
}
};
the mem-initializer-list of the user-supplied, no-arguments constructor is name(s_str, s_str + 8), rname(name), crname(name), age(-4)
. This mem-initializer-list means that the name
member is initialized by the std::string
constructor that takes two input iterators, the rname
member is initialized with a reference to name
, the crname
member is initialized with a const-reference to name
, and the age
member is initialized with the value -4
.
Each constructor has its own mem-initializer-list, and members can only be initialized in a prescribed order (basically the order in which the members are declared in the class). Thus, the members of Example
can only be initialized in the order: ptr
, name
, pname
, rname
, crname
, and age
.
When you do not specify a mem-initializer of a member, the C++ standard says:
If the entity is a nonstatic data member ... of class type ..., the entity is default-initialized (8.5). ... Otherwise, the entity is not initialized.
Here, because name
is a nonstatic data member of class type, it is default-initialized if no initializer for name
was specified in the mem-initializer-list. All other members of Example
do not have class type, so they are not initialized.
When the standard says that they are not initialized, this means that they can have any value. Thus, because the above code did not initialize pname
, it could be anything.
Note that you still have to follow other rules, such as the rule that references must always be initialized. It is a compiler error to not initialize references.
In my case a failing Jest unit test preventing the push to the repo gives the same generic error of "Error encountered while pushing to the remote repository: Git failed with a fatal error."
If you use the Generate Scripts under SSMS, click the Advanced button. Under the 'Generate Scripts for the dependent objects' option, click True. By clicking that any dependencies of each object will also be scripted out in proper order.
Use alternative HashMap implementation (Trove). Standard Java HashMap has >12x memory overhead. One can read details here.
To populate a List of String, you need not use custom row mapper. Implement it using queryForList
.
List<String>data=jdbcTemplate.queryForList(query,String.class)
In the Google Maps API v2 Demo there is a MarkerDemoActivity
class in which you can see how a custom Image is set to a GoogleMap.
// Uses a custom icon.
mSydney = mMap.addMarker(new MarkerOptions()
.position(SYDNEY)
.title("Sydney")
.snippet("Population: 4,627,300")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));
As this just replaces the marker with an image you might want to use a Canvas
to draw more complex and fancier stuff:
Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);
// paint defines the text color, stroke width and size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);
// modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);
// add marker to Map
mMap.addMarker(new MarkerOptions()
.position(USER_POSITION)
.icon(BitmapDescriptorFactory.fromBitmap(bmp))
// Specifies the anchor to be at a particular point in the marker image.
.anchor(0.5f, 1));
This draws the Canvas canvas1
onto the GoogleMap mMap
. The code should (mostly) speak for itself, there are many tutorials out there how to draw a Canvas
. You can start by looking at the Canvas and Drawables from the Android Developer page.
Now you also want to download a picture from an URL.
URL url = new URL(user_image_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is);
You must download the image from an background thread (you could use AsyncTask or Volley or RxJava for that).
After that you can replace the BitmapFactory.decodeResource(getResources(), R.drawable.user_picture_image)
with your downloaded image bmImg
.
import csv
with open('file_name.csv', 'w') as csv_file:
writer = csv.writer(csv_file)
writer.writerow(('colum1', 'colum2', 'colum3'))
for key, value in dictionary.items():
writer.writerow([key, value[0], value[1]])
This would be the simplest way to write data to .csv file
For faster and short solution you can use HashSet
instead of List
.
a.Overlaps(b);
This method is an O(n) instead of O(n^2) with two lists.
I have found that using ._getexif
doesn't work in higher python versions, moreover, it is a protected class and one should avoid using it if possible.
After digging around the debugger this is what I found to be the best way to get the EXIF data for an image:
from PIL import Image
def get_exif(path):
return Image.open(path).info['parsed_exif']
This returns a dictionary of all the EXIF data of an image.
Note: For Python3.x use Pillow instead of PIL
When $(document).ready(function (){...})
not work after page post back then use JavaScript function pageLoad in Asp.page as follow:
<script type="text/javascript" language="javascript">
function pageLoad() {
// Initialization code here, meant to run once.
}
</script>
I had a similar problem and I resolved it with:
git pull origin
Note to Sinan and brian: perlfaq3 is still wrong.
I had the same problem where there's no files under Generated Java files, BuildConfig and R.java were missing. The automatic build option is not generating.
In Eclipse under Project, uncheck Build Automatically. Then under Project select Build Project. You may need to fix the projec
You can create a new JSONObject like this:
JSONObject merged = new JSONObject();
JSONObject[] objs = new JSONObject[] { Obj1, Obj2 };
for (JSONObject obj : objs) {
Iterator it = obj.keys();
while (it.hasNext()) {
String key = (String)it.next();
merged.put(key, obj.get(key));
}
}
With this code, if you have any repeated keys between Obj1
and Obj2
the value in Obj2
will remain. If you want the values in Obj1
to be kept you should invert the order of the array in line 2.
