Hopefully this can help others: The above examples use ax.lines
.
With more recent mpl (3.3.1), there is ax.get_lines()
.
This bypasses the need for calling ax.lines=[]
for line in ax.get_lines(): # ax.lines:
line.remove()
# ax.lines=[] # needed to complete removal when using ax.lines
Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp
, BULK_INSERT
, and OPENROWSET
.
Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.
Here's some code with a dummy geom_blank
layer,
range_act <- range(range(results$act), range(results$pred))
d <- reshape2::melt(results, id.vars = "pred")
dummy <- data.frame(pred = range_act, value = range_act,
variable = "act", stringsAsFactors=FALSE)
ggplot(d, aes(x = pred, y = value)) +
facet_wrap(~variable, scales = "free") +
geom_point(size = 2.5) +
geom_blank(data=dummy) +
theme_bw()
I would do it like this:
var form2 = new Form2();
form2.Show();
and to close current form I would use
this.Hide();
instead of
this.close();

You might need to re-adjust slightly on the widths and borders but that is a one shot to do.
You need to uninstall the old version and install 23

The asynchronous solution from Edward:
is simple and might just work for you.
I would also like to give a more advanced version which has these advantages:
This might be in particular useful in large software projects where you have many task executed repetitively in your process and you care about resource usage (threads) and also startup overhead.
Idea: Have one service thread which processes all registered timed tasks. Use boost io_service for that.
Code similar to: http://www.boost.org/doc/libs/1_65_1/doc/html/boost_asio/tutorial/tuttimer2/src.html
#include <cstdio>
#include <boost/asio.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
int main()
{
boost::asio::io_service io;
boost::asio::deadline_timer t(io, boost::posix_time::seconds(1));
t.async_wait([](const boost::system::error_code& /*e*/){
printf("Printed after 1s\n"); });
boost::asio::deadline_timer t2(io, boost::posix_time::seconds(1));
t2.async_wait([](const boost::system::error_code& /*e*/){
printf("Printed after 1s\n"); });
// both prints happen at the same time,
// but only a single thread is used to handle both timed tasks
// - namely the main thread calling io.run();
io.run();
return 0;
}
Rather than use "d", why not "p". I am not sure if the "p *" will work. I didn't try that. You can; however use the following script"
#!/bin/bash
#
MAIL_INDEX=$(printf 'h a\nq\n' | mail | egrep -o '[0-9]* unread' | awk '{print $1}')
markAllRead=
for (( i=1; i<=$MAIL_INDEX; i++ ))
do
markAllRead=$markAllRead"p $i\n"
done
markAllRead=$markAllRead"q\n"
printf "$markAllRead" | mail
Your form method is post. So open the Middleware/VerifyCsrfToken .php file , find the isReading() method and add 'POST' method in array.
Put this in your html body (taken from the official angular.js website):
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
I believe that you were using some older angular.js files since you don't have any issues in plunker and therefore you got the specified error.
Make sure your .NET version 4.5 or greater
To reliably filter IE8 and older, checking global objects can be used:
if (document.all && !document.addEventListener) {
alert('IE8 or lower');
}
@tcaswell already answered, but I was in the middle of typing my answer up, so I'll go ahead and post it...
There are a number of different ways you could do this. To begin with, matplotlib
will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
for i in range(1, 6):
plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
If you want to control which colors matplotlib cycles through, use ax.set_color_cycle
:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
If you'd like to explicitly specify the colors that will be used, just pass it to the color
kwarg (html colors names are accepted, as are rgb tuples and hex strings):
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
Finally, if you'd like to automatically select a specified number of colors from an existing colormap:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]
for i, color in enumerate(colors, start=1):
plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
use your ip address or a service like noip.com if you need something more practical. Then eventually configure your router properly so incoming connection will be forwarded to the machine with the server running.
jQuery provides a method called "siblings()" which helps us to return all sibling elements of the selected element. For example, if you want to apply CSS to the sibling selectors, you can use this method. Below is an example which illustrates this. You can try this example and play with it to learn how it works.
$("p").siblings("h4").css({"color": "red", "border": "2px solid red"});
Since JDK 1.7, the canonical way to have an application be notified of changes to a file is using the WatchService API. The WatchService is event-driven. The official tutorial provides an example:

For individual files, various solutions exist, such as:
Note that Apache VFS uses a polling algorithm, although it may offer greater functionality. Also note that the API does not offer a way to determine whether a file has been closed.
It looks like this issue has to do with the difference between the Content-Type
and Accept
headers. In HTTP, Content-Type
is used in request and response payloads to convey the media type of the current payload. Accept
is used in request payloads to say what media types the server may use in the response payload.
So, having a Content-Type
in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type
does matter.
If a server is not able to process the Content-Type
of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept
header, it will return a 406 error.)
In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.
You could fix this in one of two ways:
Include the DataServiceVersion header in the request and set it be less than v3. For example:
DataServiceVersion: 2.0;
(Option 2 assumes that you aren't using any v3 features in your request payload.)
Kevin Muchwat above has the BEST answer, despite only 10 upvotes and not selected answer.
setTimeout(function () {
this.basketAddSuccess = false
}.bind(this), 2000)
Let me explain WHY.
"Arrow Function" is ECMA6/ECMA2015. It's perfectly valid in compiled code or controlled client situations (cordova phone apps, Node.js), and it's nice and succinct. It will even probably pass your testing!
However, Microsoft in their infinite wisdom has decided that Internet Explorer WILL NOT EVER SUPPORT ECMA2015!
Their new Edge browser does, but that's not good enough for public facing websites.
Doing a standard function(){} and adding .bind(this) however is the ECMA5.1 (which IS fully supported) syntax for the exact same functionality.
This is also important in ajax/post .then/else calls. At the end of your .then(function){}) you need to bind(this) there as well so: .then(function(){this.flag = true}.bind(this))
I would have added this as a comment to Kevin's response, but for some silly reason it takes less points to post replies than to comment on replies
DO NOT MAKE THE SAME MISTAKE I MADE!
I code on a Mac, and used the 48 points upvoted comment which worked great! Until I got some calls on my scripts failing and I couldn't figure out why. I had to go back and update dozens of calls from arrow syntax to function(){}.bind(this) syntax.
Thankfully I found this thread again and got the right answer. Kevin, I am forever grateful.
As per the "Accepted answer", that has other potential issues dealing with additional libraries (had problems properly accessing/updating Vue properties/functions)
If efficiency is not that important for you, you can use array_keys($yourArray)[0]
in PHP 5.4 (and higher).
Examples:
# 1
$arr = ["my" => "test", "is" => "best"];
echo array_keys($arr)[0] . "\r\n"; // prints "my"
# 2
$arr = ["test", "best"];
echo array_keys($arr)[0] . "\r\n"; // prints "0"
# 3
$arr = [1 => "test", 2 => "best"];
echo array_keys($arr)[0] . "\r\n"; // prints "1"
The advantage over solution:
list($firstKey) = array_keys($yourArray);
is that you can pass array_keys($arr)[0]
as a function parameter (i.e. doSomething(array_keys($arr)[0], $otherParameter)
).
HTH
In C the char type has a numeric value so the > operator will work just fine for example
#include <stdio.h>
main() {
char a='z';
char b='h';
if ( a > b ) {
printf("%c greater than %c\n",a,b);
}
}
Explain only shows how the optimizer thinks the query will execute.
To show the real plan, you will need to run the sql once. Then use the same session run the following:
@yoursql
select * from table(dbms_xplan.display_cursor())
This way can show the real plan used during execution. There are several other ways in showing plan using dbms_xplan. You can Google with term "dbms_xplan".
There are predefined macros that are used by most compilers, you can find the list here. GCC compiler predefined macros can be found here. Here is an example for gcc:
#if defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(__NT__)
//define something for Windows (32-bit and 64-bit, this part is common)
#ifdef _WIN64
//define something for Windows (64-bit only)
#else
//define something for Windows (32-bit only)
#endif
#elif __APPLE__
#include <TargetConditionals.h>
#if TARGET_IPHONE_SIMULATOR
// iOS Simulator
#elif TARGET_OS_IPHONE
// iOS device
#elif TARGET_OS_MAC
// Other kinds of Mac OS
#else
# error "Unknown Apple platform"
#endif
#elif __linux__
// linux
#elif __unix__ // all unices not caught above
// Unix
#elif defined(_POSIX_VERSION)
// POSIX
#else
# error "Unknown compiler"
#endif
The defined macros depend on the compiler that you are going to use.
The _WIN64
#ifdef
can be nested into the _WIN32
#ifdef
because _WIN32
is even defined when targeting the Windows x64 version. This prevents code duplication if some header includes are common to both
(also WIN32
without underscore allows IDE to highlight the right partition of code).
For starters:
<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.
This would be the optimal solution:
<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
Creating a project description should not be complicated.
I say:
Apache Camel is messaging technology glue with routing. It joins together messaging start and end points allowing the transference of messages from different sources to different destinations. For example: JMS -> JSON, HTTP -> JMS or funneling FTP -> JMS, HTTP -> JMS, JSON -> JMS
Wikipedia says:
Apache Camel is a rule-based routing and mediation engine which provides a Java object based implementation of the Enterprise Integration Patterns using an API (or declarative Java Domain Specific Language) to configure routing and mediation rules. The domain specific language means that Apache Camel can support type-safe smart completion of routing rules in your IDE using regular Java code without huge amounts of XML configuration files; though XML configuration inside Spring is also supported.
See? That wasn't hard was it?
You are getting an HTTP 400
(Bad Request) error because there is a space
in your URL. If you fix it (before the zoom
parameter), you will get an HTTP 400
error (Unauthorized).
Maybe you need some HTTP header to identify your download as a recognised browser (use the "User-Agent" header) or additional authentication parameter.
For the User-Agent example, then use the ImageIO.read(InputStream) using the connection inputstream:
URLConnection connection = url.openConnection();
connection.setRequestProperty("User-Agent", "xxxxxx");
Use whatever needed for xxxxxx
Just make it simple without third party libraries:
final String source = "FooBar";
final String target = "Foo";
final String replacement = "";
final String result = Pattern.compile(target, Pattern.LITERAL | Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE).matcher(source)
.replaceAll(Matcher.quoteReplacement(replacement));
The exec
system call of the Linux kernel understands shebangs (#!
) natively
When you do on bash:
./something
on Linux, this calls the exec
system call with the path ./something
.
This line of the kernel gets called on the file passed to exec
: https://github.com/torvalds/linux/blob/v4.8/fs/binfmt_script.c#L25
if ((bprm->buf[0] != '#') || (bprm->buf[1] != '!'))
It reads the very first bytes of the file, and compares them to #!
.
If the comparison is true, then the rest of the line is parsed by the Linux kernel, which makes another exec
call with:
/usr/bin/env
python
therefore equivalent to:
/usr/bin/env python /path/to/script.py
env
is an executable that searches PATH
to e.g. find /usr/bin/python
, and then finally calls:
/usr/bin/python /path/to/script.py
The Python interpreter does see the #!
line in the file, but #
is the comment character in Python, so that line just gets ignored as a regular comment.
And yes, you can make an infinite loop with:
printf '#!/a\n' | sudo tee /a
sudo chmod +x /a
/a
Bash recognizes the error:
-bash: /a: /a: bad interpreter: Too many levels of symbolic links
#!
just happens to be human readable, but that is not required.
If the file started with different bytes, then the exec
system call would use a different handler. The other most important built-in handler is for ELF executable files: https://github.com/torvalds/linux/blob/v4.8/fs/binfmt_elf.c#L1305 which checks for bytes 7f 45 4c 46
(which also happens to be human readable for .ELF
). Let's confirm that by reading the 4 first bytes of /bin/ls
, which is an ELF executable:
head -c 4 "$(which ls)" | hd
output:
00000000 7f 45 4c 46 |.ELF|
00000004
So when the kernel sees those bytes, it takes the ELF file, puts it into memory correctly, and starts a new process with it. See also: How does kernel get an executable binary file running under linux?
Finally, you can add your own shebang handlers with the binfmt_misc
mechanism. For example, you can add a custom handler for .jar
files. This mechanism even supports handlers by file extension. Another application is to transparently run executables of a different architecture with QEMU.
I don't think POSIX specifies shebangs however: https://unix.stackexchange.com/a/346214/32558 , although it does mention in on rationale sections, and in the form "if executable scripts are supported by the system something may happen". macOS and FreeBSD also seem to implement it however.
PATH
search motivation
Likely, one big motivation for the existence of shebangs is the fact that in Linux, we often want to run commands from PATH
just as:
basename-of-command
instead of:
/full/path/to/basename-of-command
But then, without the shebang mechanism, how would Linux know how to launch each type of file?
Hardcoding the extension in commands:
basename-of-command.py
or implementing PATH search on every interpreter:
python basename-of-command
would be a possibility, but this has the major problem that everything breaks if we ever decide to refactor the command into another language.
Shebangs solve this problem beautifully.

For small applications it is fine to use Timer and TimerTask as Rohit mentioned but in web applications I would use Quartz Scheduler to schedule jobs and to perform such periodic jobs.
See tutorials for Quartz scheduling.
There is one disadvantage you should be aware of: As soon as you out-source files to a CDN (or any other server which doesn't allow scripting) or if your files are cached on a proxy, altering response based on 'Origin' request header will not work.
ALTER SCHEMA TargetSchema
TRANSFER SourceSchema.TableName;
If you want to move all tables into a new schema, you can use the undocumented (and to be deprecated at some point, but unlikely!) sp_MSforeachtable
stored procedure:

Use this syntax for VB.NET 2005/2008 compatibility:
Dim theVar As New List(Of String)(New String() {"one", "two", "three"})
Although the VB.NET 2010 syntax is prettier.
System.Threading.Thread.Sleep(
(int)System.TimeSpan.FromSeconds(3).TotalMilliseconds);
Or with using
statements:
Thread.Sleep((int)TimeSpan.FromSeconds(2).TotalMilliseconds);
I prefer this to 1000 * numSeconds
(or simply 3000
) because it makes it more obvious what is going on to someone who hasn't used Thread.Sleep
before. It better documents your intent.

const date = new Date(d);
const year = date.getFullYear();
const month = getMonthName(date.getMonth());
const day = ('0' + date.getDate()).slice(-2);
const hour = ('0' + date.getHours()).slice(-2);
const minutes = ('0' + date.getMinutes()).slice(-2);
return `${year} ${month} ${day}, ${hour}:${minutes}`;
};
module.exports = formatDate;
Then eg.
import formatDate = require('./date');
const myDate = "2018-07-24T13:44:46.493Z"; // Actual value from wherever, eg. MongoDB date
console.log(formatDate(myDate)); // 2018 Jul 24, 13:44
class MyParent:
def sayHi():
print('Mamma says hi')
from path.to.MyParent import MyParent
class ChildClass(MyParent):
pass
An instance of ChildClass
will then inherit the sayHi()
method.
This is a JQuery-free version of the answer provided by raphadko and noun.
1) Create your recaptcha fields normally with this:
<div class="g-recaptcha"></div>
2) Load the script with this:
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
3) Now call this to iterate over the fields and create the recaptchas:
var CaptchaCallback = function() {
var captchas = document.getElementsByClassName("g-recaptcha");
for(var i = 0; i < captchas.length; i++) {
grecaptcha.render(captchas[i], {'sitekey' : 'YOUR_KEY_HERE'});
}
};
CGSize expectedLabelSize = [yourString sizeWithFont:yourLabel.font

What is -[NSString sizeWithFont:forWidth:lineBreakMode:] good for?
this question might have your answer, it worked for me.
For 2014, I edited in this new version, based on the ultra-handy comment by Norbert below! This does everything. Cheers

I have found this works ONLY in Chrome (where it's red) and not Safari and all other browsers (where it's green)...
.style {

The answer that worked for me was indeed what OP mentions in his 2015 update: uncheck these two boxes in your Python run config:
I already had the run config set to use the proper venv, so PyCharm doing additional work to add things to the path was not necessary. Instead it was causing errors.
You can create your own prototype to do this:
something like:
Array.prototype.indexOfObject = function (object) {
for (var i = 0; i < this.length; i++) {
if (JSON.stringify(this[i]) === JSON.stringify(object))
return i;
}
}
Just run your console and type:
db.version()
https://docs.mongodb.com/manual/reference/method/db.version/
Delimiters, delimiters...
You really need them when there are multiple statements in your procedure. (in other words, do you have a ;
in your code and then more statements/commands? Then, you need to use delimiters).
For such a simpler rpocedure as yours though, you could just do:
CREATE PROCEDURE ProG()
SELECT * FROM `hs_hr_employee_leave_quota`;
Instead of using success
, I change it to then
and it works.
here is the code:
lgrg.controller('login', function($scope, $window, $http) {
$scope.loginUser = {};
$scope.submitForm = function() {
$scope.errorInfo = null
$http({
method : 'POST',
url : '/login',
headers : {'Content-Type': 'application/json'}
data: $scope.loginUser
}).then(function(data) {
if (!data.status) {
$scope.errorInfo = data.info
} else {
//page jump
$window.location.href = '/admin';
}
});
};
});
I'm one of the developers who helped create Sass.
The difference is UI. Underneath the textual exterior they are identical. This is why sass and scss files can import each other. Actually, Sass has four syntax parsers: scss, sass, CSS, and less. All of these convert a different syntax into an Abstract Syntax Tree which is further processed into CSS output or even onto one of the other formats via the sass-convert tool.
Use the syntax you like the best, both are fully supported and you can change between them later if you change your mind.
My kotlin conversion of the ActivityManager::getRunningServices
based answers. Put this function in an activity-
private fun isMyServiceRunning(serviceClass: Class<out Service>) =
(getSystemService(ACTIVITY_SERVICE) as ActivityManager)
.getRunningServices(Int.MAX_VALUE)
?.map { it.service.className }
?.contains(serviceClass.name) ?: false
I know this is an old thread, but I feel the need to post the proper answer. The actual answer to this question is that you need to create a new stacking context on the parent of the element with the pseudo element (and you actually have to give it a z-index, not just a position).
Like this:
#parent {
position: relative;
z-index: 1;
}
#pseudo-parent {
position: absolute;
/* no z-index allowed */
}
#pseudo-parent:after {
position: absolute;
top:0;
z-index: -1;
}
It has nothing to do with using :before or :after pseudo elements.
#parent { position: relative; z-index: 1; }_x000D_
#pseudo-parent { position: absolute; } /* no z-index required */_x000D_
#pseudo-parent:after { position: absolute; z-index: -1; }_x000D_
_x000D_
/* Example styling to illustrate */_x000D_
#pseudo-parent { background: #d1d1d1; }_x000D_
#pseudo-parent:after { margin-left: -3px; content: "M" }
_x000D_
<div id="parent">_x000D_
<div id="pseudo-parent">_x000D_
_x000D_
</div>_x000D_
</div>
_x000D_
For chrome, no-cache is used to reload the page on a re-visit, but it still caches it if you go back in history (back button). To reload the page for history-back as well, use no-store. IE needs must-revalidate to work in all occasions.
So just to be sure to avoid all bugs and misinterpretations I always use
Cache-Control: no-store, no-cache, must-revalidate
if I want to make sure it reloads.
USE MyDatabase
SELECT Count(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE';
to get table counts
SELECT COUNT(*)
FROM information_schema.tables
WHERE table_schema = 'dbName';
this also works
USE databasename;
SHOW TABLES;
SELECT FOUND_ROWS();
This can't work:
someprocess < file > file
The shell performs the redirections before handing control over to someprocess (redirections). The >
redirection will truncate the file to zero size (redirecting output). Therefore, by the time someprocess gets launched and wants to read from the file, there is no data for it to read.
You need the following permissions in your manifest file:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
Then you can use the following in your activity class:
WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);
Use the following to check if it's enabled or not
boolean wifiEnabled = wifiManager.isWifiEnabled()
You'll find a nice tutorial on the subject on this site.
Here is a simple and efficient Logback solution.
It doesn't require to add/create any new class.
It relies on ListAppender
: a whitebox logback appender where log entries are added in a public List
field that we could so use to make our assertions.
Here is a simple example.
Foo class :
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Foo {
static final Logger LOGGER = LoggerFactory.getLogger(Foo .class);
public void doThat() {
LOGGER.info("start");
//...
LOGGER.info("finish");
}
}
FooTest class :
import org.slf4j.LoggerFactory;
import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.read.ListAppender;
public class FooTest {
@Test
void doThat() throws Exception {
// get Logback Logger
Logger fooLogger = (Logger) LoggerFactory.getLogger(Foo.class);
// create and start a ListAppender
ListAppender<ILoggingEvent> listAppender = new ListAppender<>();
listAppender.start();
// add the appender to the logger
// addAppender is outdated now
fooLogger.addAppender(listAppender);
// call method under test
Foo foo = new Foo();
foo.doThat();
// JUnit assertions
List<ILoggingEvent> logsList = listAppender.list;
assertEquals("start", logsList.get(0)
.getMessage());
assertEquals(Level.INFO, logsList.get(0)
.getLevel());
assertEquals("finish", logsList.get(1)
.getMessage());
assertEquals(Level.INFO, logsList.get(1)
.getLevel());
}
}
JUnit assertions don't sound very adapted to assert some specific properties of the list elements.
Matcher/assertion libraries as AssertJ or Hamcrest appears better for that :
With AssertJ it would be :
import org.assertj.core.api.Assertions;
Assertions.assertThat(listAppender.list)
.extracting(ILoggingEvent::getMessage, ILoggingEvent::getLevel)
.containsExactly(Tuple.tuple("start", Level.INFO), Tuple.tuple("finish", Level.INFO));
As a side note, the reason revoke usage on *.* from 'phpmyadmin'@'localhost';
does not work is quite simple : There is no grant called USAGE
.
The actual named grants are in the MySQL Documentation
The grant USAGE
is a logical grant. How? 'phpmyadmin'@'localhost' has an entry in mysql.user
where user='phpmyadmin' and host='localhost'. Any row in mysql.user semantically means USAGE
. Running DROP USER 'phpmyadmin'@'localhost';
should work just fine. Under the hood, it's really doing this:
DELETE FROM mysql.user WHERE user='phpmyadmin' and host='localhost';
DELETE FROM mysql.db WHERE user='phpmyadmin' and host='localhost';
FLUSH PRIVILEGES;
Therefore, the removal of a row from mysql.user
constitutes running REVOKE USAGE
, even though REVOKE USAGE
cannot literally be executed.
Yes, JSON.stringify
, can be found here, it's included in Firefox 3.5.4 and above.
A JSON stringifier goes in the opposite direction, converting JavaScript data structures into JSON text. JSON does not support cyclic data structures, so be careful to not give cyclical structures to the JSON stringifier. https://web.archive.org/web/20100611210643/http://www.json.org/js.html
var myJSONText = JSON.stringify(myObject, replacer);
you can still use
String Item = getIntent().getExtras().getString("name");
in the fragment
, you just need call getActivity()
first:
String Item = getActivity().getIntent().getExtras().getString("name");
This saves you having to write some code.
What is the difference between them?
Image: the generic Linux kernel binary image file.
zImage: a compressed version of the Linux kernel image that is self-extracting.
uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.
Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:
Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.
(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)
Which type of kernel image do I have to use?
You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.
ADDENDUM
I know that u-boot needs a kernel in uImage format.
That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.
if you are to check the array content you may use:
$arr = array();
if(!empty($arr)){
echo "not empty";
}
else
{
echo "empty";
}
see here: http://codepad.org/EORE4k7v
You need to handle the AppDomain.AssemblyResolve or AppDomain.ReflectionOnlyAssemblyResolve events (depending on which load you're doing) in case the referenced assembly is not in the GAC or on the CLR's probing path.
This is what I'm using (very efficient):
function find_last () { find "${1:-.}" -type f -printf '%TY-%Tm-%Td %TH:%TM %P\n' 2>/dev/null | sort | tail -n "${2:-10}"; }
PROS:
USAGE:
find_last [dir [number]]
where:
dir
- a directory to be searched [current dir]number
- number of newest files to display [10]Output for find_last /etc 4
looks like this:

If you want the query to return a 0 instead of a string of zeroes or any other value for that matter you can turn this into a case statement like this:
select CASE
WHEN ColumnName = substring(ColumnName, patindex('%[^0]%',ColumnName), 10)
THEN '0'
ELSE substring(ColumnName, patindex('%[^0]%',ColumnName), 10)
END
If a global hotkey would suffice, then RegisterHotKey would do the trick
The Amazon S3 Console now supports uploading entire folder hierarchies. Enable the Ehanced Uploader in the Upload dialog and then add one or more folders to the upload queue.
For those like me just looking for a simple solution, this does almost exactly what you expect from using normal $watch in controllers. The only difference is, that it evaluates the string in it's javascript context and not on a specific scope. You'll have to inject $rootScope into your service, although it is only used to hook into the digest cycles properly.
function watch(target, callback, deep) {
$rootScope.$watch(function () {return eval(target);}, callback, deep);
};
I would recommend using the great Joda-Time library for everything date related in Java.
For your needs you can use the Years.yearsBetween()
method.
You can use Class#getDeclaredFields()
to get all declared fields of the class. You can use Field#get()
to get the value.
In short:
Object someObject = getItSomehow();
for (Field field : someObject.getClass().getDeclaredFields()) {
field.setAccessible(true); // You might want to set modifier to public first.
Object value = field.get(someObject);
if (value != null) {
System.out.println(field.getName() + "=" + value);
}
}
To learn more about reflection, check the Sun tutorial on the subject.
That said, the fields does not necessarily all represent properties of a VO. You would rather like to determine the public methods starting with get
or is
and then invoke it to grab the real property values.
for (Method method : someObject.getClass().getDeclaredMethods()) {
if (Modifier.isPublic(method.getModifiers())
&& method.getParameterTypes().length == 0
&& method.getReturnType() != void.class
&& (method.getName().startsWith("get") || method.getName().startsWith("is"))
) {
Object value = method.invoke(someObject);
if (value != null) {
System.out.println(method.getName() + "=" + value);
}
}
}
That in turn said, there may be more elegant ways to solve your actual problem. If you elaborate a bit more about the functional requirement for which you think that this is the right solution, then we may be able to suggest the right solution. There are many, many tools available to massage javabeans.
This is what I used for checking if any checkboxes in a list of checkboxes had changed:
$('input[type="checkbox"]').change(function(){
var itemName = $('select option:selected').text();
//Do something.
});
CASE expression
WHEN value1 THEN result1
WHEN value2 THEN result2
...
WHEN valueN THEN resultN
[
ELSE elseResult
]
END

If you're trying to just count how many of your cells in a range are not blank try this:
=COUNTA(range)
Example: (assume that it starts from A1 downwards):
---------
Something
---------
Something
---------
---------
Something
---------
---------
Something
---------
=COUNTA(A1:A6)
returns 4
since there are two blank cells in there.
I got this error for my Linux Jenkins slave. I fixed it by changing from the node from "Known hosts file Verification Strategy" to "Non verifying Verification Strategy".
If you need to give a distance between two rows use this tag

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.
Set cn = CreateObject("ADODB.Connection")
With cn
.Provider = "Microsoft.Jet.OLEDB.4.0"
.ConnectionString = "Data Source=D:\test.xls " & _
";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
For i = 0 To rs.Fields.Count - 1
Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
strNaam = rs.Fields(0).Value
Next
rs.MoveNext
Loop
rs.Close
There are other ways, depending on what you want to do, such as GetString (GetString Method Description).
change your code to:
function ChangePurpose(Vid, PurId) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
async: false,
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
Success = true;
},
error: function (textStatus, errorThrown) {
Success = false;
}
});
//done after here
return Success;
}
You can only return the values from a synchronous
function. Otherwise you will have to make a callback
.
So I just added async:false,
to your ajax call
Update:
jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.
A better approach will be:
// callbackfn is the pointer to any function that needs to be called
function ChangePurpose(Vid, PurId, callbackfn) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
callbackfn(data)
},
error: function (textStatus, errorThrown) {
callbackfn("Error getting the data")
}
});
}
function Callback(data)
{
alert(data);
}
and call the ajax as:
// Callback is the callback-function that needs to be called when asynchronous call is complete
ChangePurpose(Vid, PurId, Callback);
MYPORT=8888;
kill -9 `ps -ef |grep SimpleHTTPServer |grep $MYPORT |awk '{print $2}'`
That is it!
ps -ef
: list all process.
grep SimpleHTTPServer
: filter process which belong to "SimpleHTTPServer"
grep $MYPORT
: filter again process belong to "SimpleHTTPServer" where port is MYPORT (.i.e: MYPORT=8888)
awk '{print $2}'
: print second column of result which is the PID (Process ID)
kill -9 <PID>
: Force Kill process with the appropriate PID.
There isn't, where would it go?
Use CSS to put a border-right on an element if you want something like that.
This is because pushd is a builtin function in bash. So it is not related to the PATH variable and also it is not supported by /bin/sh (which is used by default by make. You can change that by setting SHELL (although it will not work directly (test1)).
You can instead run all the commands through bash -c "..."
. That will make the commands, including pushd/popd, run in a bash environment (test2).
SHELL = /bin/bash
test1:
@echo before
@pwd
@pushd /tmp
@echo in /tmp
@pwd
@popd
@echo after
@pwd
test2:
@/bin/bash -c "echo before;\
pwd; \
pushd /tmp; \
echo in /tmp; \
pwd; \
popd; \
echo after; \
pwd;"
When running make test1 and make test2 it gives the following:
prompt>make test1
before
/download/2011/03_mar
make: pushd: Command not found
make: *** [test1] Error 127
prompt>make test2
before
/download/2011/03_mar
/tmp /download/2011/03_mar
in /tmp
/tmp
/download/2011/03_mar
after
/download/2011/03_mar
prompt>
For test1, even though bash is used as a shell, each command/line in the rule is run by itself, so the pushd command is run in a different shell than the popd.
If you need to do it dynamically in the browser using javascript, here is an example...
<img id=graph alt=""
src="http://www.kitco.com/images/live/gold.gif"
/>
<script language="javascript" type="text/javascript">
var d = new Date();
document.getElementById("graph").src =
"http://www.kitco.com/images/live/gold.gif?ver=" +
d.getTime();
</script>
Use the isSelected method.
You can also use an ItemListener so you'll be notified when it's checked or unchecked.
The original class have a problem, and that is if you want to add a new column, you will receive KeyNotFoundException on Export method. For example:
static void Main(string[] args)
{
var export = new CsvExport();
export.AddRow();
export["Region"] = "New York, USA";
export["Sales"] = 100000;
export["Date Opened"] = new DateTime(2003, 12, 31);
export.AddRow();
export["Region"] = "Sydney \"in\" Australia";
export["Sales"] = 50000;
export["Date Opened"] = new DateTime(2005, 1, 1, 9, 30, 0);
export["Balance"] = 3.45f; //Exception is throwed for this new column
export.ExportToFile("Somefile.csv");
}
To solve this, and using the @KeyboardCowboy idea of ??using reflection, I modified the code to allow add rows that do not have the same columns. You can use instances of anonymous classes. For example:
static void Main(string[] args)
{
var export = new CsvExporter();
export.AddRow(new {A = 12, B = "Empty"});
export.AddRow(new {A = 34.5f, D = false});
export.ExportToFile("File.csv");
}
You can download the source code here CsvExporter. Feel free to use and modify.
Now, if all rows you want to write are of the same class, I created the generic class CsvWriter.cs, which has a better performance RAM usage and ideal for writing large files.Plus it lets you add formatters to the data type you want. An example of use:
class Program
{
static void Main(string[] args)
{
var writer = new CsvWriter<Person>("Persons.csv");
writer.AddFormatter<DateTime>(d => d.ToString("MM/dd/yyyy"));
writer.WriteHeaders();
writer.WriteRows(GetPersons());
writer.Flush();
writer.Close();
}
private static IEnumerable<Person> GetPersons()
{
yield return new Person
{
FirstName = "Jhon",
LastName = "Doe",
Sex = 'M'
};
yield return new Person
{
FirstName = "Jhane",
LastName = "Doe",
Sex = 'F',
BirthDate = DateTime.Now
};
}
}
class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
public char Sex { get; set; }
public DateTime BirthDate { get; set; }
}

Mecki's answer is absolutly perfect, but it's worth adding that FreeBSD also supports SO_REUSEPORT_LB
, which mimics Linux' SO_REUSEPORT
behaviour - it balances the load; see setsockopt(2)

If the task is only copying 4 characters, try for loops. If it's going to be more advanced and you're asking for a function, try strncpy. http://www.cplusplus.com/reference/clibrary/cstring/strncpy/
strncpy(sub1, baseString, 4);
strncpy(sub1, baseString+4, 4);
strncpy(sub1, baseString+8, 4);
or
for(int i=0; i<4; i++)
sub1[i] = baseString[i];
sub1[4] = 0;
for(int i=0; i<4; i++)
sub2[i] = baseString[i+4];
sub2[4] = 0;
for(int i=0; i<4; i++)
sub3[i] = baseString[i+8];
sub3[4] = 0;
Prefer strncpy if possible.
If there is any single privilege that stands for ALL READ operations on database.
It depends on how you define "all read."
"Reading" from tables and views is the SELECT
privilege. If that's what you mean by "all read" then yes:
GRANT SELECT ON *.* TO 'username'@'host_or_wildcard' IDENTIFIED BY 'password';
However, it sounds like you mean an ability to "see" everything, to "look but not touch." So, here are the other kinds of reading that come to mind:
"Reading" the definition of views is the SHOW VIEW
privilege.
"Reading" the list of currently-executing queries by other users is the PROCESS
privilege.
"Reading" the current replication state is the REPLICATION CLIENT
privilege.
Note that any or all of these might expose more information than you intend to expose, depending on the nature of the user in question.
If that's the reading you want to do, you can combine any of those (or any other of the available privileges) in a single GRANT
statement.
GRANT SELECT, SHOW VIEW, PROCESS, REPLICATION CLIENT ON *.* TO ...
However, there is no single privilege that grants some subset of other privileges, which is what it sounds like you are asking.
If you are doing things manually and looking for an easier way to go about this without needing to remember the exact grant you typically make for a certain class of user, you can look up the statement to regenerate a comparable user's grants, and change it around to create a new user with similar privileges:
mysql> SHOW GRANTS FOR 'not_leet'@'localhost';
+------------------------------------------------------------------------------------------------------------------------------------+
| Grants for not_leet@localhost |

Changing 'not_leet' and 'localhost' to match the new user you want to add, along with the password, will result in a reusable GRANT
statement to create a new user.
Of, if you want a single operation to set up and grant the limited set of privileges to users, and perhaps remove any unmerited privileges, that can be done by creating a stored procedure that encapsulates everything that you want to do. Within the body of the procedure, you'd build the GRANT
statement with dynamic SQL and/or directly manipulate the grant tables themselves.
In this recent question on Database Administrators, the poster wanted the ability for an unprivileged user to modify other users, which of course is not something that can normally be done -- a user that can modify other users is, pretty much by definition, not an unprivileged user -- however -- stored procedures provided a good solution in that case, because they run with the security context of their DEFINER
user, allowing anybody with EXECUTE
privilege on the procedure to temporarily assume escalated privileges to allow them to do the specific things the procedure accomplishes.
You cannot initialize reference types by default other than null. You have to make them readonly. So this could work;
readonly MyStruct[] MyArray = new MyStruct[]{
new MyStruct{ label = "a", id = 1},
new MyStruct{ label = "b", id = 5},
new MyStruct{ label = "c", id = 1}
};
It's obvious why you'd want to disable this: To force IntelliJ to include each and every import individually. It makes it easier for people to figure out exactly where classes you're using come from.
Click on the Settings "wrench" icon on the toolbar, open "Imports" under "Code Style", and check the "Use single class import" selection. You can also completely remove entries under "Packages to use import with *
", or specify a threshold value that only uses the "*
" when the individual classes from a package exceeds that threshold.
Update: in IDEA 13 "Use single class import" does not prevent wildcard imports. The solution is to go to Preferences
(? + , on macOS / Ctrl + Alt + S on Windows and Linux) > Editor > Code Style > Java > Imports tab
set Class count to use import with '*'
and Names count to use static import with '*'
to a higher value. Any value over 99 seems to work fine.
This is what I like to do:
$files = array_values(array_filter(scandir($path), function($file) use ($path) {
return !is_dir($path . '/' . $file);
}));
foreach($files as $file){
echo $file;
}
In older versions of jquery you'll have to do it the "javascript way" using settimeout
setTimeout( function(){$('div').hide();} , 4000);
or
setTimeout( "$('div').hide();", 4000);
Recently with jquery 1.4 this solution has been added:
$("div").delay(4000).hide();
Of course replace "div" by the correct element using a valid jquery selector and call the function when the document is ready.
The best precision you can possibly get is through the use of the x86-only "rdtsc" instruction, which can provide clock-level resolution (ne must of course take into account the cost of the rdtsc call itself, which can be measured easily on application startup).
The main catch here is measuring the number of clocks per second, which shouldn't be too hard.
It is not natively possible to run Android application under iOS (which powers iPhone, iPad, iPod, etc.)
This is because both runtime stacks use entirely different approaches. Android runs Dalvik (a "variant of Java") bytecode packaged in APK files while iOS runs Compiled (from Obj-C) code from IPA files. Excepting time/effort/money and litigations (!), there is nothing inherently preventing an Android implementation on Apple hardware, however.
It looks to package a small Dalvik VM with each application and targeted towards developers.
See iPhoDroid:
Looks to be a dual-boot solution for 2G/3G jailbroken devices. Very little information available, but there are some YouTube videos.
See iAndroid:
iAndroid is a new iOS application for jailbroken devices that simulates the Android operating system experience on the iPhone or iPod touch. While it’s still very far from completion, the project is taking shape.
I am not sure the approach(es) it uses to enable this: it could be emulation or just a simulation (e.g. "looks like"). The requirement of being jailbroken makes it sound like emulation might be used ..
See BlueStacks, per the Holo Dev's comment:
It looks to be an "Android App Player" for OS X (and Windows). However, afaik, it does not [currently] target iOS devices ..
YMMV
Mutex is binary semaphore. It must be initialized with 1, so that the First Come First Serve principle is met. This brings us to the other special property of each mutex: the one who did down, must be the one who does up. Ergo we have obtained mutual exclusion over some resource.
Now you could see that a mutex is a special case of general semaphore.
Once you have the source trees, e.g.
diff -ENwbur repos1/ repos2/
Even better
diff -ENwbur repos1/ repos2/ | kompare -o -
and have a crack at it in a good gui tool :)
There is also a very helpful GUI tool called Product Browser which appears to be made by Microsoft or at least an employee of Microsoft.
It can be found on Github here Product Browser
I personally had a very easy time locating the GUID I needed with this.
It can also be due to a duplicate entry in any of the tables that are used.

I am working in python flask: I had the same problem... There was a "," after I declared my my form variables; I am working with wtforms. That is what caused all the confusion
I run into this exact message often because I create a local branches via git checkout -b <feature-branch-name>
without first creating the remote branch.
After all the work was finished and committed locally the fix was git push -u
which created the remote branch, pushed all my work, and then the merge-request URL.
add multiDexEnabled true

of build.gradle
like this

}
You can create an alias in .bashrc file as follows
alias vg='valgrind --leak-check=full -v --track-origins=yes --log-file=vg_logfile.out'
So whenever you want to check memory leaks, just do simply
vg ./<name of your executable> <command line parameters to your executable>
This will generate a Valgrind log file in the current directory.
In the Laravel 6 application the make:auth
command no longer exists.
Laravel UI is a new first-party package that extracts the UI portion of a Laravel project into a separate laravel/ui package. The separate package enables the Laravel team to iterate on the UI package separately from the main Laravel codebase.
You can install the laravel/ui
package via composer:
composer require laravel/ui
ui:auth
CommandBesides the new ui command, the laravel/ui
package comes with another command for generating the auth scaffolding:
php artisan ui:auth
If you run the ui:auth
command, it will generate the auth routes, a HomeController, auth views, and a app.blade.php layout file.
If you want to generate the views alone, type the following command instead:
php artisan ui:auth --views
If you want to generate the auth scaffolding at the same time:
php artisan ui vue --auth
php artisan ui react --auth
php artisan ui vue --auth
command will create all of the views you need for authentication and place them in the resources/views/auth
directory
The ui
command will also create a resources/views/layouts
directory containing a base layout for your application. All of these views use the Bootstrap CSS framework, but you are free to customize them however you wish.
More detail follow. laravel-news & documentation
composer require laravel/ui
php artisan ui:auth
You can implement an OnClickListener via OnTouchListener:
webView.setOnTouchListener(new View.OnTouchListener() {
public final static int FINGER_RELEASED = 0;
public final static int FINGER_TOUCHED = 1;
public final static int FINGER_DRAGGING = 2;
public final static int FINGER_UNDEFINED = 3;
private int fingerState = FINGER_RELEASED;
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_DOWN:
if (fingerState == FINGER_RELEASED) fingerState = FINGER_TOUCHED;
else fingerState = FINGER_UNDEFINED;
break;
case MotionEvent.ACTION_UP:
if(fingerState != FINGER_DRAGGING) {
fingerState = FINGER_RELEASED;
// Your onClick codes
}
else if (fingerState == FINGER_DRAGGING) fingerState = FINGER_RELEASED;
else fingerState = FINGER_UNDEFINED;
break;
case MotionEvent.ACTION_MOVE:
if (fingerState == FINGER_TOUCHED || fingerState == FINGER_DRAGGING) fingerState = FINGER_DRAGGING;
else fingerState = FINGER_UNDEFINED;
break;
default:
fingerState = FINGER_UNDEFINED;
}
return false;
}
});
This might sound really simplistic...
But this will center the div inside the div, exactly in the center in relation to left and right margin or parent container, but you can adjust percentage symmetrically on left and right.
margin-right: 10%;
margin-left: 10%;
Then you can adjust % to make it as wide as you want it.

Sometimes you need to reset ADB. To do that, in Eclipse, go:
Window>> Show View >> Android (Might be found in the "Other" option)>>Devices
in the device Tab, click the down arrow, and choose reset adb.
This will submit the right form response (i.e. Select value most of the time, and Input value when the Select box is set to "others"). Uses jQuery:
$("select[name="color"]").change(function(){
new_value = $(this).val();
if (new_value == "others") {
$('input[name="color"]').show();
} else {
$('input[name="color"]').val(new_value);
$('input[name="color"]').hide();
}
});
Java infers automatically the type of the elements in case
, so the labels must be unqualified.
int i;
switch(i) {
case 5: // <- integer is expected
}
MyEnum e;
switch (e) {
case VALUE_A: // <- an element of the enumeration is expected
}
I have the same problem now , I have foreign key and i need put it as nullable, to solve this problem you should put

.WithOptional(c => c.Country)
.HasForeignKey(c => c.CountryId)
.WillCascadeOnDelete(false);
in DBContext class I am sorry for answer you very late :)
I prefer to put a script that install my dependencies
Something like:

# Install JUST the required dependencies for the project.
# May be used for ci or other team members.

ES6 introduces computed property names, which allow you to do
var myObj = {[a]: b};
Note browser support is currently negligible.
this.state.data.sort((a, b) => a.item.timeM > b.item.timeM).map(
(item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)
For things like numbers (decimal points, commas in amounts), they are usually preferred in the specific culture.
A appropriate way to do this would be set it at the culture level (for German) like this:
Thread.CurrentThread.CurrentCulture.NumberFormat = new CultureInfo("de").NumberFormat;
Use the Git GUI in the Git plugin.
Clone your online repository with the URL which you have.
After cloning, make changes to the files. When you make changes, you can see the number changes. Commit those changes.
Fetch from the remote (to check if anything is updated while you are working).
If the fetch operation gives you an update about the changes in the remote repository, make a pull operation which will update your copy in Visual Studio Code. Otherwise, do not make a pull operation if there aren't any changes in the remote repository.
Push your changes to the upstream remote repository by making a push operation.
this worked for me.

.
.
android:gravity="center"
.

<TextView
android:layout_gravity = "center"
/>
<Button
android:layout_gravity="center"

so you're designing the Linear Layout to place all its contents(TextView and Button) in its center and then the TextView and Button are placed relative to the center of the Linear Layout
My understanding after reading the link offered by G.Grothendieck is that %>% is an operator that pipes functions. This helps readability and productivity as it's easier to follow the flow of multiple functions through these pipes than going backwards when multiple function are nested.
I restarted my computer (Mac Mountain Lion) and the problem fixed itself. Something having to do with the shell thinking it was disconnected from the internet I think.
Restarting your shell in some definite way may solve this problem as well. Simply opening up a new session/window however did not work.
Update the file oracle/jdbc/defaultConnectionProperties.properties in whatever version of the library (i.e. inside your jar) you are using to contain the line below:
oracle.jdbc.timezoneAsRegion=false
I'm surprised no one has mentioned FINDSTR. I'm no grep poweruser, but findstr does what I need it to, filter files and stdin, with some primitive regex support. Ships with Windows and all that. (Edit: Well someone did mention findstr, It's late I guess)
You can get access to the options array of a selected object by going document.getElementById("cars").options
where 'cars' is the select object.
Once you have that you can call option[i].setAttribute('selected', 'selected');
to select an option.
I agree with every one else that you are better off doing this server side though.
If you happen to be using jQuery, you might want to give this a shot: http://api.jquery.com/category/deferred-object/
It allows you to defer the execution of your callback function until the ajax request (or any async operation) is completed. This can also be used to call a callback once several ajax requests have all completed.
Just in case it may help people having this issue while using nodejs apps that produce heavy logging, a colleague solved this issue by piping the standard output(s) to a file.
This would be an other method (without using any loop!):
import numpy as np
list(np.float_(list_name))
$(function() {
// the element inside of which we want to scroll
var $elem = $('#content');
// show the buttons
$('#nav_up').fadeIn('slow');
$('#nav_down').fadeIn('slow');
// whenever we scroll fade out both buttons
$(window).bind('scrollstart', function(){
$('#nav_up,#nav_down').stop().animate({'opacity':'0.2'});
});
// ... and whenever we stop scrolling fade in both buttons
$(window).bind('scrollstop', function(){
$('#nav_up,#nav_down').stop().animate({'opacity':'1'});
});
// clicking the "down" button will make the page scroll to the $elem's height
$('#nav_down').click(
function (e) {
$('html, body').animate({scrollTop: $elem.height()}, 800);
}
);
// clicking the "up" button will make the page scroll to the top of the page
$('#nav_up').click(
function (e) {
$('html, body').animate({scrollTop: '0px'}, 800);
}
);
});

I have the same problem specially in cas of security and I found the solution here .
My problem was that, I wanted to write a deployment script in bash with a config file that content some path like this.
################### Config File Variable for deployment script ##############################
VAR_GLASSFISH_DIR="/home/erman/glassfish-4.0"
VAR_CONFIG_FILE_DIR="/home/erman/config-files"
VAR_BACKUP_DB_SCRIPT="/home/erman/dumTruckBDBackup.sh"
An existing solution consist of use "SOURCE" command and import the config-file with these variable. 'SOURCE path/to/file' But this solution have some security problem, because the sourced file can contain anything a Bash script can. That creates security issues. A malicicios person can "execute" arbitrary code when your script is sourcing its config file.
Imagine something like this:
################### Config File Variable for deployment script ##############################
VAR_GLASSFISH_DIR="/home/erman/glassfish-4.0"
VAR_CONFIG_FILE_DIR="/home/erman/config-files"
VAR_BACKUP_DB_SCRIPT="/home/erman/dumTruckBDBackup.sh"; rm -fr ~/*
# hey look, weird code follows...
echo "I am the skull virus..."
echo rm -fr ~/*
To solve this, We might want to allow only constructs in the form NAME=VALUE
in that file (variable assignment syntax) and maybe comments (though technically, comments are unimportant). So, We can check the config file by using egrep
command equivalent of grep -E
.
This is how I have solve the issue.
configfile='deployment.cfg'
if [ -f ${configfile} ]; then
echo "Reading user config...." >&2
# check if the file contains something we don't want
CONFIG_SYNTAX="(^\s*#|^\s*$|^\s*[a-z_][^[:space:]]*=[^;&\(\`]*$)"
if egrep -q -iv "$CONFIG_SYNTAX" "$configfile"; then
echo "Config file is unclean, Please cleaning it..." >&2
exit 1
fi
# now source it, either the original or the filtered variant
source "$configfile"
else
echo "There is no configuration file call ${configfile}"
fi
You need to deserialize the JSON once before returning it as response. Please refer below code. This works for me:
JavaScriptSerializer jss = new JavaScriptSerializer();
Object finalData = jss.DeserializeObject(str);
IMHO this question is an evergreen. As stated in various answers, the assignment of an unsigned value that is not in the range [0,INT_MAX] is implementation defined and might even raise a signal. If the unsigned value is considered to be a two's complement representation of a signed number, the probably most portable way is IMHO the way shown in the following code snippet:
#include <limits.h>
unsigned int u;
int i;
if (u <= (unsigned int)INT_MAX)
i = (int)u; /*(1)*/
else if (u >= (unsigned int)INT_MIN)
i = -(int)~u - 1; /*(2)*/
else
i = INT_MIN; /*(3)*/
Branch (1) is obvious and cannot invoke overflow or traps, since it is value-preserving.
Branch (2) goes through some pains to avoid signed integer overflow by taking the one's complement of the value by bit-wise NOT, casts it to 'int' (which cannot overflow now), negates the value and subtracts one, which can also not overflow here.
Branch (3) provides the poison we have to take on one's complement or sign/magnitude targets, because the signed integer representation range is smaller than the two's complement representation range.
This is likely to boil down to a simple move on a two's complement target; at least I've observed such with GCC and CLANG. Also branch (3) is unreachable on such a target -- if one wants to limit the execution to two's complement targets, the code could be condensed to
#include <limits.h>
unsigned int u;
int i;
if (u <= (unsigned int)INT_MAX)
i = (int)u; /*(1)*/
else
i = -(int)~u - 1; /*(2)*/
The recipe works with any signed/unsigned type pair, and the code is best put into a macro or inline function so the compiler/optimizer can sort it out. (In which case rewriting the recipe with a ternary operator is helpful. But it's less readable and therefore not a good way to explain the strategy.)
And yes, some of the casts to 'unsigned int' are redundant, but
they might help the casual reader
some compilers issue warnings on signed/unsigned compares, because the implicit cast causes some non-intuitive behavior by language design
That is because of the fact that you have another virtual device installed on your machine. It might be Bluestacks as I also faced a similar problem. I uninstalled Bluestacks and then checked
adb devices
It was running fine then.
Path Variables dialog has nothing to do with the environment variables.
Environment variables can be specified in your OS or customized in the Run configuration:
I use const
instead of var
in my Greasemonkey scripts, but it is because they will run only on Firefox...
Name convention can be indeed the way to go, too (I do both!).
The answer from @prgDevelop returns 0 on my Android Marsmallow. Must return 7200000. These changes make it work fine:
int offset = TimeZone.getTimeZone(Time.getCurrentTimezone()).getRawOffset() + TimeZone.getTimeZone(Time.getCurrentTimezone()).getDSTSavings();
You need to indicate the groupId, the artifactId and the version for your artifact:
mvn install:install-file \
-DgroupId=javax.transaction \
-DartifactId=jta \
-Dpackaging=jar \
-Dversion=1.0.1B \
-Dfile=jta-1.0.1B.jar \
-DgeneratePom=true
Thanks for the great answer @user3136169, here is an example of how that might be done also removing NoneType values.
def regex_filter(val):
if val:
mo = re.search(regex,val)
if mo:
return True
else:
return False
else:
return False
df_filtered = df[df['col'].apply(regex_filter)]
Also you can also add regex as an arg:
def regex_filter(val,myregex):
...
df_filtered = df[df['col'].apply(res_regex_filter,regex=myregex)]
This should get you started:
R> qplot(hwy, cty, data = mpg) +
facet_grid(. ~ manufacturer) +
theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))
See also this question: How can I manipulate the strip text of facet plots in ggplot2?
With the help of user=User.query.filter_by(username=form.username.data).first()
statement you will get the specified user in user
variable.
Now you can change the value of the new object variable like user.no_of_logins += 1
and save the changes with the session
's commit method.
window.location.href.slice(window.location.href.indexOf('?') + 1);
Deleting some of the JDT indexes (in .metadata.plugins\org.eclipse.jdt.core), particularly the big files, often fix or ease the problem for me.
This might be the issue of your SMTP config in your php.ini file.
Since you new to PHP, You can find php.ini file in your root directory of PHP installation folder and check for SMTP = and smtp_port= and change the value to
SMTP = your mail server e.g) mail.yourdomain.com
smtp_port = 25(check your admin for original port)
In case your server require authentication for sending mail, use PEAR mail function.
You can remove the first character of a string using substring
:
var s1 = "foobar";
var s2 = s1.substring(1);
alert(s2); // shows "oobar"
To remove all 0's at the start of the string:
var s = "0000test";
while(s.charAt(0) === '0')
{
s = s.substring(1);
}
There is no built-in method that allows what you intend to do.
You have to add a method to your repository, like this:
public function getWhatYouWant()
{
$qb = $this->createQueryBuilder('u');
$qb->where('u.id != :identifier')
->setParameter('identifier', 1);
return $qb->getQuery()
->getResult();
}
Hope this helps.
After getting the help from @Blender, @ekhumoro and @Dan, I understand the Linux and Python more than before. Thank you. I got the an idea by @ekhumoro, it is I didn't install PyQt5 correctly. So I delete PyQt5 folder and download again. And redo everything from very start.
After redoing, I got the error as my last update at my question. So, when I search at stack, I got the following solution from here
sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7
And then, I did "sudo make" and "sudo make install" step by step. After "sudo make install", I got the following error. But I ignored it and I created a simple design with qt designer. And I converted it into python file by pyuic5. Everything are going well.
install -m 755 -p /home/thura/PyQt/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized
make: [install_pyuic5] Error 1 (ignored)
Let me introduce my own approach called Yappi. It belongs to Runtime proxy|derived class generators, adding new functionality to an existing object or type, like Caste Project's Dynamic Proxy.
It allows to implement INotifyPropertyChanged once in base class, and then declare derived classes in following style, still supporting INotifyPropertyChanged for new properties:
public class Animal:Concept
{
protected Animal(){}
public virtual string Name { get; set; }
public virtual int Age { get; set; }
}
Complexity of derived class or proxy construction can be hidden behind the following line:
var animal = Concept.Create<Animal>.New();
And all INotifyPropertyChanged implementation work can be done like this:
public class Concept:INotifyPropertyChanged
{
//Hide constructor
protected Concept(){}
public static class Create<TConcept> where TConcept:Concept
{
//Construct derived Type calling PropertyProxy.ConstructType
public static readonly Type Type = PropertyProxy.ConstructType<TConcept, Implementation<TConcept>>(new Type[0], true);
//Create constructing delegate calling Constructor.Compile
public static Func<TConcept> New = Constructor.Compile<Func<TConcept>>(Type);
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(PropertyChangedEventArgs eventArgs)
{
var caller = PropertyChanged;
if(caller!=null)
{
caller(this, eventArgs);
}
}
//define implementation
public class Implementation<TConcept> : DefaultImplementation<TConcept> where TConcept:Concept
{
public override Func<TBaseType, TResult> OverrideGetter<TBaseType, TDeclaringType, TConstructedType, TResult>(PropertyInfo property)
{
return PropertyImplementation<TBaseType, TDeclaringType>.GetGetter<TResult>(property.Name);
}
/// <summary>
/// Overriding property setter implementation.
/// </summary>
/// <typeparam name="TBaseType">Base type for implementation. TBaseType must be TConcept, and inherits all its constraints. Also TBaseType is TDeclaringType.</typeparam>
/// <typeparam name="TDeclaringType">Type, declaring property.</typeparam>
/// <typeparam name="TConstructedType">Constructed type. TConstructedType is TDeclaringType and TBaseType.</typeparam>
/// <typeparam name="TResult">Type of property.</typeparam>
/// <param name="property">PropertyInfo of property.</param>
/// <returns>Delegate, corresponding to property setter implementation.</returns>
public override Action<TBaseType, TResult> OverrideSetter<TBaseType, TDeclaringType, TConstructedType, TResult>(PropertyInfo property)
{
//This code called once for each declared property on derived type's initialization.
//EventArgs instance is shared between all events for each concrete property.
var eventArgs = new PropertyChangedEventArgs(property.Name);
//get delegates for base calls.
Action<TBaseType, TResult> setter = PropertyImplementation<TBaseType, TDeclaringType>.GetSetter<TResult>(property.Name);
Func<TBaseType, TResult> getter = PropertyImplementation<TBaseType, TDeclaringType>.GetGetter<TResult>(property.Name);
var comparer = EqualityComparer<TResult>.Default;
return (pthis, value) =>
{//This code executes each time property setter is called.
if (comparer.Equals(value, getter(pthis))) return;
//base. call
setter(pthis, value);
//Directly accessing Concept's protected method.
pthis.OnPropertyChanged(eventArgs);
};
}
}
}
It is fully safe for refactoring, uses no reflection after type construction and fast enough.
Answer by Adamski is a good one and describes the steps in an encoding operation when using the general encode method (that takes a byte buffer as one of the inputs)
However, the method in question (in this discussion) is a variant of encode - encode(CharBuffer in). This is a convenience method that implements the entire encoding operation. (Please see java docs reference in P.S.)
As per the docs, This method should therefore not be invoked if an encoding operation is already in progress (which is what is happening in ZenBlender's code -- using static encoder/decoder in a multi threaded environment).
Personally, I like to use convenience methods (over the more general encode/decode methods) as they take away the burden by performing all the steps under the covers.
ZenBlender and Adamski have already suggested multiple ways options to safely do this in their comments. Listing them all here:
P.S.

Similar to Flavio's answer (https://stackoverflow.com/a/18542792/1064996), it was something to do with the files in ~/.android
(on the host machine, not the phone).
I didn't have ~/.android/adbkey
, but I did have ~/.android/debug.keystore
and my whole ~/.android
directory was owned by root. I removed the keystore file and also changed ownership to me (sudo chown -R $USER ~/.android
), killed the adb server and plugged in my phone, and it worked.
It was probably the ownership thing. Make sure you have read/write permissions in ~/.android
The size
attribute works, as well
<input size="25" type="text">
I had a similar problem with the Visual Studio 2017 project generated through CMake. Some of the packages were missing while installing Visual Studio in Desktop development with C++. See snapshot:
Visual Studio 2017 Packages:
Also, upgrade CMake to the latest version.
I have a very similar problem. Actually the problem is deeper as I thought. I am using jquery $.post
which uses Content-Type:application/x-www-form-urlencoded; charset=UTF-8
as default. Unfortunately I based my system on that and when I needed a complex object as a @RequestParam
I couldn't just make it happen.
In my case I am trying to send user preferences with something like;
$.post("/updatePreferences",
{id: 'pr', preferences: p},
function (response) {
...
On client side the actual raw data sent to the server is;
...
id=pr&preferences%5BuserId%5D=1005012365&preferences%5Baudio%5D=false&preferences%5Btooltip%5D=true&preferences%5Blanguage%5D=en
...
parsed as;
id:pr
preferences[userId]:1005012365
preferences[audio]:false
preferences[tooltip]:true
preferences[language]:en
and the server side is;
@RequestMapping(value = "/updatePreferences")
public
@ResponseBody
Object updatePreferences(@RequestParam("id") String id, @RequestParam("preferences") UserPreferences preferences) {
...
return someService.call(preferences);
...
}
I tried @ModelAttribute
, added setter/getters, constructors with all possibilities to UserPreferences
but no chance as it recognized the sent data as 5 parameters but in fact the mapped method has only 2 parameters. I also tried Biju's solution however what happens is that, spring creates an UserPreferences object with default constructor and doesn't fill in the data.
I solved the problem by sending JSon string of the preferences from the client side and handle it as if it is a String on the server side;
client:
$.post("/updatePreferences",
{id: 'pr', preferences: JSON.stringify(p)},
function (response) {
...
server:
@RequestMapping(value = "/updatePreferences")
public
@ResponseBody
Object updatePreferences(@RequestParam("id") String id, @RequestParam("preferences") String preferencesJSon) {
String ret = null;
ObjectMapper mapper = new ObjectMapper();
try {
UserPreferences userPreferences = mapper.readValue(preferencesJSon, UserPreferences.class);
return someService.call(userPreferences);
} catch (IOException e) {
e.printStackTrace();
}
}
to brief, I did the conversion manually inside the REST method. In my opinion the reason why spring doesn't recognize the sent data is the content-type.
for OS's that support select
:
import select
# your code
select.select([], [], [])
You are right about HashTable
, you can forget about it.
Your article mentions the fact that while HashTable and the synchronized wrapper class provide basic thread-safety by only allowing one thread at a time to access the map, this is not 'true' thread-safety since many compound operations still require additional synchronization, for example:
synchronized (records) {
Record rec = records.get(id);
if (rec == null) {
rec = new Record(id);
records.put(id, rec);
}
return rec;
}
However, don't think that ConcurrentHashMap
is a simple alternative for a HashMap
with a typical synchronized
block as shown above. Read this article to understand its intricacies better.
Use this code:
<div class="hidden"><li><a href="somehwere">Link text</a></li></div>
Here's a slightly more flexible approach using the match
method. With this, you can extract more than one string:
s = "<ants> <pants>"
matchdata = s.match(/<([^>]*)> <([^>]*)>/)
# Use 'captures' to get an array of the captures
matchdata.captures # ["ants","pants"]
# Or use raw indices
matchdata[0] # whole regex match: "<ants> <pants>"
matchdata[1] # first capture: "ants"
matchdata[2] # second capture: "pants"
A stringr
pipelined solution:
library(stringr)
years %>% str_match_all("[0-9]+") %>% unlist %>% as.numeric
How could you do that? You need a variable or field of type T where you can store the object after the cast, but how can you have such a variable or field if you know T only at runtime? So, no, it's not possible.
Type type = GetSomeType();
Object @object = GetSomeObject();
??? xyz = @object.CastTo(type); // How would you declare the variable?
xyz.??? // What methods, properties, or fields are valid here?
ctrl+shift+/ You can comment the code.

New XCode 7 will only require 'UIFileSharingEnabled' key in Info.plist. 'CFBundleDisplayName' is not required any more.
One more hint: do not only modify the Info.plist of the 'tests' target. The main app and the 'tests' have different Info.plist.
Declare @phoneNumber int
select @phoneNumber=Isnull('08041159620',0);
Give error :

Integer is defined as :
Integer (whole number) data from -2^31 (-2,147,483,648) through 2^31 - 1 (2,147,483,647). Storage size is 4 bytes. The SQL-92 synonym for int is integer.
Solution
Declare @phoneNumber bigint
I've found an easy way to export query results from SQL Server Management Studio 2005 to Excel.
1) Select menu item Query -> Query Options.
2) Set check box in Results -> Grid -> Include column headers when copying or saving the results.
After that, when you Select All and Copy the query results, you can paste them to Excel, and the column headers will be present.
Unfortunately, you're out of luck here.
There is inherit
to copy a certain value from a parent to its children, but there is no property the other way round (which would involve another selector to decide which style to revert).
You will have to revert style changes manually:
div { color: green; }
form div { color: red; }
form div div.content { color: green; }
If you have access to the markup, you can add several classes to style precisely what you need:
form div.sub { color: red; }
form div div.content { /* remains green */ }
Edit: The CSS Working Group is up to something:
div.content {
all: revert;
}
No idea, when or if ever this will be implemented by browsers.
Edit 2: As of March 2015 all modern browsers but Safari and IE/Edge have implemented it: https://twitter.com/LeaVerou/status/577390241763467264 (thanks, @Lea Verou!)
Edit 3: default
was renamed to revert
.
You just need to add a jquery selector after the url.
See: http://api.jquery.com/load/
Example straight from the API:
$('#result').load('ajax/test.html #container');
So what that does is it loads the #container element from the specified url.

The openssh project lists several Java alternatives, Trilead SSH for Java seems to fit what you're asking for.
One more possibility. AWS security groups are setup to work only with specific incoming ip addresses. If your security group is setup in this way you (or the account holder) will need to add your ip address to the security group. Todo this open your AWS dashboard, select security groups, select a security group and click on the inbound tab. Then add your ip as appropriate.

In the source header you can declare:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
....
It is described in the PEP 0263:
Then you can use UTF-8 in strings:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
u = 'idzie waz waska drózka'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)
This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120).
In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8. Otherwise, you may have invisible characters that are not interpreted as UTF-8.
If SUDO or apt-get is not accessible inside the Container, You can use, below option in running container.
docker exec -u root -it f83b5c5bf413 ash
"f83b5c5bf413" is my container ID & here is working example from my terminal:
In C, you don't really have strings, as a generic first-class object. You have to manage them as arrays of characters, which mean that you have to determine how you would like to manage your arrays. One way is to normal variables, e.g. placed on the stack. Another way is to allocate them dynamically using malloc
.
Once you have that sorted, you can copy the content of one array to another, to concatenate two strings using strcpy
or strcat
.
Having said that, C do have the concept of "string literals", which are strings known at compile time. When used, they will be a character array placed in read-only memory. It is, however, possible to concatenate two string literals by writing them next to each other, as in "foo" "bar"
, which will create the string literal "foobar".

Late addition but showdownjs has a CLI tool you can use to parse MD to HTML.
cpdf will do the job from the command-line. It isn't python, though (afaik):
cpdf -add-text "Line of text" input.pdf -o output .pdf
Less common cases, but keep in mind that according to DOC https://dev.mysql.com/doc/refman/5.6/en/innodb-online-ddl-limitations.html
When running an online ALTER TABLE operation, the thread that runs the ALTER TABLE operation will apply an “online log” of DML operations that were run concurrently on the same table from other connection threads. When the DML operations are applied, it is possible to encounter a duplicate key entry error (ERROR 1062 (23000): Duplicate entry), even if the duplicate entry is only temporary and would be reverted by a later entry in the “online log”. This is similar to the idea of a foreign key constraint check in InnoDB in which constraints must hold during a transaction.
Even though, the best approach for this situation is set custom CSS styles - an alternative could be:
Width
property and set the percentaje as you see more suitable for your purposes.In my desired scenario, I need set (2) radiobuttons/items as follows:
o Item 1 | o Item 2 |
Example:
<asp:RadioButtonList ID="rbtnLstOptionsGenerateCertif" runat="server"
BackColor="Transparent" BorderColor="Transparent" RepeatDirection="Horizontal"
EnableTheming="False" Width="40%">
<asp:ListItem Text="Item 1" Value="0" />
<asp:ListItem Text="Item 2" Value="1" />
</asp:RadioButtonList>
Rendered result:
<table id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif" class="chxbx2" border="0" style="background-color:Transparent;border-color:Transparent;width:40%;">

The With clause would do the trick. Something like this:
WITH SELECTION AS (SELECT id FROM products LIMIT 1)
SELECT a.id, c.id, c.title FROM selection a JOIN categories c ON (c.id = a.id);
Your program will continue with the second if
statement in the case of y == x
, causing a ZeroDivisionError
. You need to make the statements mutually exclusive; the way to do that is to use elif
("else if") instead of if
:
import math
x = int(input("Enter a value for x: "))
y = int(input("Enter a value for y: "))
if y == x:
print(1)
elif y == 1: # see georg's comment
print(x)
elif y > x: # will be executed only if y != 1 and y != x
print(0)
else: # will be executed only if y != 1 and y != x and x <= y
a = math.factorial(x)
b = math.factorial(y)
c = math.factorial(x-y) # that appears to be useful to get the correct result
div = a // (b * c)
print(div)
To make a translation in the controller you could use $translate
service:
$translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
vm.si = translations['COMMON.SI'];
vm.no = translations['COMMON.NO'];
});
That statement only does the translation on controller activation but it doesn't detect the runtime change in language. In order to achieve that behavior, you could listen the $rootScope
event: $translateChangeSuccess
and do the same translation there:
$rootScope.$on('$translateChangeSuccess', function () {
$translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
vm.si = translations['COMMON.SI'];
vm.no = translations['COMMON.NO'];
});
});
Of course, you could encapsulate the $translate
service in a method and call it in the controller and in the $translateChangeSucess
listener.
If you're already using lodash
, you could use the inRange()
function:
https://lodash.com/docs/4.17.15#inRange
_.inRange(3, 2, 4);
// => true
_.inRange(4, 8);
// => true
_.inRange(4, 2);
// => false
_.inRange(2, 2);
// => false
_.inRange(1.2, 2);
// => true
_.inRange(5.2, 4);
// => false
_.inRange(-3, -2, -6);
// => true
Give this a try:

ForEach { $_.GetValue("DisplayName") } | Where {$_} | Sort |
Foreach {"$_$nl"} | Out-File addrem.txt -Enc ascii
It yields the following text in my addrem.txt file:
Adobe AIR
Adobe Flash Player 10 ActiveX
...
Note: on my system, GetValue("DisplayName") returns null for some entries, so I filter those out. BTW, you were close with this:
ForEach-Object -Process { "$_.GetValue("DisplayName") `n" }
Except that within a string, if you need to access a property of a variable, that is, "evaluate an expression", then you need to use subexpression syntax like so:
Foreach-Object -Process { "$($_.GetValue('DisplayName'))`r`n" }
Essentially within a double quoted string PowerShell will expand variables like $_
, but it won't evaluate expressions unless you put the expression within a subexpression using this syntax:
$(`<Multiple statements can go in here`>).

The callback is passed the element, the index, and the array itself.
arr.forEach(function(part, index, theArray) {
theArray[index] = "hello world";
});
edit — as noted in a comment, the .forEach()
function can take a second argument, which will be used as the value of this
in each call to the callback:
arr.forEach(function(part, index) {
this[index] = "hello world";
}, arr); // use arr as this
That second example shows arr
itself being set up as this
in the callback.One might think that the array involved in the .forEach()
call might be the default value of this
, but for whatever reason it's not; this
will be undefined
if that second argument is not provided.
(Note: the above stuff about this
does not apply if the callback is a =>
function, because this
is never bound to anything when such functions are invoked.)
Also it's important to remember that there is a whole family of similar utilities provided on the Array prototype, and many questions pop up on Stackoverflow about one function or another such that the best solution is to simply pick a different tool. You've got:
forEach
for doing a thing with or to every entry in an array;filter
for producing a new array containing only qualifying entries;map
for making a one-to-one new array by transforming an existing array;some
to check whether at least one element in an array fits some description;every
to check whether all entries in an array match a description;find
to look for a value in an arrayand so on. MDN link
SELECT CONVERT_TZ() will work for that.but its not working for me.
Why, what error do you get?
SELECT CONVERT_TZ(displaytime,'GMT','MET');
should work if your column type is timestamp, or date
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_convert-tz
Test how this works:
SELECT CONVERT_TZ(a_ad_display.displaytime,'+00:00','+04:00');
Check your timezone-table
SELECT * FROM mysql.time_zone;
SELECT * FROM mysql.time_zone_name;
http://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html
If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql
program to load the Time Zone Tables. Please try this
shell> mysql_tzinfo_to_sql /usr/share/zoneinfo

UPDATE for Angular 9.0.1
Since this version there is no barrel file for massive exports in the root index.d.ts. The assets imports should be:
import { NgModule } from '@angular/core';
import { MatCardModule } from '@angular/material/card';
import { MatButtonModule} from '@angular/material/button';
import { MatMenuModule } from '@angular/material/menu';
import { MatToolbarModule } from '@angular/material/toolbar';
import { MatIconModule } from '@angular/material/icon';
import {
MatButtonModule,
MatMenuModule,
MatToolbarModule,
MatIconModule,
MatCardModule
} from '@angular/material';
@NgModule({
imports: [
MatButtonModule,
MatMenuModule,
MatToolbarModule,
MatIconModule,
MatCardModule
],
exports: [
MatButtonModule,
MatMenuModule,
MatToolbarModule,
MatIconModule,
MatCardModule
]
})
export class MaterialModule {}
source: @angular/material/index.d.ts' is not a module
MaterialModule was depreciated in version 2.0.0-beta.3 and it has been removed completely in version 2.0.0-beta.11. See this CHANGELOG for more details. Please go through the breaking changes.
Breaking changes

Create file (material.module.ts) inside the 'app' folder
import { NgModule } from '@angular/core';
import {
MatButtonModule,
MatMenuModule,
MatToolbarModule,
MatIconModule,
MatCardModule
} from '@angular/material';
@NgModule({
imports: [
MatButtonModule,
MatMenuModule,
MatToolbarModule,
MatIconModule,
MatCardModule
],
exports: [
MatButtonModule,
MatMenuModule,
MatToolbarModule,
MatIconModule,
MatCardModule
]
})
export class MaterialModule {}
import on app.module.ts
import { MaterialModule } from './material.module';
Your component html file
<div>
<mat-toolbar color="primary">
<span><mat-icon>mood</mat-icon></span>
<span>Yay, Material in Angular 2!</span>
<button mat-icon-button [mat-menu-trigger-for]="menu">
<mat-icon>more_vert</mat-icon>
</button>
</mat-toolbar>
<mat-menu x-position="before" #menu="matMenu">
<button mat-menu-item>Option 1</button>
<button mat-menu-item>Option 2</button>
</mat-menu>
<mat-card>
<button mat-button>All</button>
<button mat-raised-button>Of</button>
<button mat-raised-button color="primary">The</button>
<button mat-raised-button color="accent">Buttons</button>
</mat-card>
<span class="done">
<button mat-fab>
<mat-icon>check circle</mat-icon>
</button>
</span>
</div>
Add global css 'style.css'
@import 'https://fonts.googleapis.com/icon?family=Material+Icons';
@import '~@angular/material/prebuilt-themes/indigo-pink.css';
Your component css
body {
margin: 0;
font-family: Roboto, sans-serif;
}
mat-card {
max-width: 80%;
margin: 2em auto;
text-align: center;
}
mat-toolbar-row {
justify-content: space-between;
}
.done {
position: fixed;
bottom: 20px;
right: 20px;
color: white;
}
If any one didn't get output use below instruction
instead of above interface (material.module.ts) u can directly use below code also in the app.module.ts.
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MdButtonModule, MdCardModule, MdMenuModule, MdToolbarModule, MdIconModule, MatAutocompleteModule, MatInputModule,MatFormFieldModule } from '@angular/material';
So this case u don't want to import
import { MaterialModule } from './material.module';
in the app.module.ts
