First time I have added a video link for solving your problem but I learned it was a bad idea. This time I'll explain it briefly.
Android studio is compatible with github but you need adjust something:
Setup the Github plugins in the Android Studio settings
Download the git version control system from this link and setup https://git-scm.com/
settings >> version control >> git
program files >> git >> bin >> git.exe
Settings >> Version control >> Github
you will see login and password for your Github account. Apply the settings.VCS >> enable version control integration >> git
VCS >> import into version control >> share project on Github
and enter your master password. Now you can use VCS update buttons for updating your project to Github
If you have to iterate over the first len(a)
items of an object b
(that is larger than a
), you should probably use range(len(a))
:
for i in range(len(a)):
do_something_with(b[i])
My issue was inside of my app.gradle. I ran into this issue when I moved
apply plugin: "com.android.application"

You can use
cd /You folder name
svn commit 'your file path' -m "Commit message you want to give"
You can also drage you files to command promt instead to write cd [common in MAC OSx]

Sorry that was a typo. You can either add node_modules to the end of your user's global path variable, or maybe check the permissions associated with that folder (node _modules). The error doesn't seem like the last case, but I've encountered problems similar to yours. I find the first solution enough for most cases. Just go to environment variables and add the path to node_modules to the last part of your user's path variable. Note I'm saying user and not system.
Just add a semicolon to the end of the variable declaration and add the static path to your node_module folder. ( Ex c:\path\to\node_module)
Alternatively you could:
In your CMD
PATH=%PATH%;C:\\path\to\node_module
EDIT
The last solution will work as long as you don't close your CMD. So, use the first solution for a permanent change.
Your CRON should look like this:
*/5 * * * *
CronWTF is really usefull when you need to test out your CRON settings.
Might be a good idea to pipe the output into a log file so you can see if your script is throwing any errors too - since you wont see them in your terminal.
Also try using a shebang at the top of your PHP file, so the system knows where to find PHP. Such as:
#!/usr/bin/php
that way you can call the whole thing like this
*/5 * * * * php /path/to/script.php > /path/to/logfile.log
I faced a problem that I had to use a timer, but I had to display them in 2 component same time, same screen. I created the timerObservable in a service. I subscribed to the timer in both component, and what happened? It won't be synched, cause new subscription always creates its own stream.
What I would like to say, is that if you plan to use one timer at several places, always put .publishReplay(1).refCount()
at the end of the Observer, cause it will publish the same stream out of it every time.
Example:
this.startDateTimer = Observable.combineLatest(this.timer, this.startDate$, (localTimer, startDate) => {
return this.calculateTime(startDate);
}).publishReplay(1).refCount();
you certainly won't succeed with
tail -f /var/log/foo.log |grep --line-buffered string2search
when you use "colortail" as an alias for tail, eg. in bash
alias tail='colortail -n 30'
you can check by
type alias
if this outputs something like
tail isan alias of colortail -n 30
.
then you have your culprit :)
Solution:
remove the alias with
unalias tail
ensure that you're using the 'real' tail binary by this command
type tail
which should output something like:
tail is /usr/bin/tail
and then you can run your command
tail -f foo.log |grep --line-buffered something
Good luck.
The most efficient way would be using a matcher to continually find the expressions and replace them, then append the text to a string builder:
Pattern pattern = Pattern.compile("\\[(.+?)\\]");
Matcher matcher = pattern.matcher(text);
HashMap<String,String> replacements = new HashMap<String,String>();
//populate the replacements map ...
StringBuilder builder = new StringBuilder();
int i = 0;
while (matcher.find()) {
String replacement = replacements.get(matcher.group(1));
builder.append(text.substring(i, matcher.start()));
if (replacement == null)
builder.append(matcher.group(0));
else
builder.append(replacement);
i = matcher.end();
}
builder.append(text.substring(i, text.length()));
return builder.toString();
As others have said, Dir::foreach
is a good option here. However, note that Dir::foreach
and Dir::entries
will always include .
and ..
(the current and parent directories). You will generally not want to work on them, so you can use Dir::each_child
or Dir::children
(as suggested by ma11hew28) or do something like this:
Dir.foreach('/path/to/dir') do |filename|
next if filename == '.' or filename == '..'
# Do work on the remaining files & directories
end
Dir::foreach
and Dir::entries
(as well as Dir::each_child
and Dir::children
) also include hidden files & directories. Often this is what you want, but if it isn't, you need to do something to skip over them.
Alternatively, you might want to look into Dir::glob
which provides simple wildcard matching:
Dir.glob('/path/to/dir/*.rb') do |rb_filename|
# Do work on files & directories ending in .rb
end
One point not pointed out yet, is the speed. I know it's an old answered question, but I think this deserves direct comment/answer:
They would seem to be redundant as the same can be done with derived tables
When I used CTE the very first time I was absolutely stunned by it's speed. It was a case like from a textbook, very suitable for CTE, but in all ocurences I ever used CTE, there was a significant speed gain. My first query was complex with derived tables, taking long minutes to execute. With CTE it took fractions of seconds and left me shocked, that it is even possible.
If you want to check repetition more than 1 in descending order then implement below query.
SELECT duplicate_data,COUNT(duplicate_data) AS duplicate_data
FROM duplicate_data_table_name
GROUP BY duplicate_data
HAVING COUNT(duplicate_data) > 1
ORDER BY COUNT(duplicate_data) DESC
If want simple count query.
SELECT COUNT(duplicate_data) AS duplicate_data
FROM duplicate_data_table_name
GROUP BY duplicate_data
ORDER BY COUNT(duplicate_data) DESC
var mailcopy = document.getElementById('mailCopy').checked;

array.reduce(0, :+)
While equivalent to array.inject(0, :+)
, the term reduce is entering a more common vernacular with the rise of MapReduce programming models.
inject, reduce, fold, accumulate, and compress are all synonymous as a class of folding functions. I find consistency across your code base most important, but since various communities tend to prefer one word over another, it’s nonetheless useful to know the alternatives.
To emphasize the map-reduce verbiage, here’s a version that is a little bit more forgiving on what ends up in that array.
array.map(&:to_i).reduce(0, :+)
Some additional relevant reading:
I hope you want to access the current directory including the package i.e. If your Java program is in c:\myApp\com\foo\src\service\MyTest.java
and you want to print until c:\myApp\com\foo\src\service
then you can try the following code:
String myCurrentDir = System.getProperty("user.dir")
+ File.separator
+ System.getProperty("sun.java.command")
.substring(0, System.getProperty("sun.java.command").lastIndexOf("."))
.replace(".", File.separator);
System.out.println(myCurrentDir);
Note: This code is only tested in Windows with Oracle JRE.
"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur. (From other SO answer)
So you can't do anything about it, it is the issue of the server.
But you could use try .. except
block to handle that exception:
from socket import error as SocketError
import errno
try:
response = urllib2.urlopen(request).read()
except SocketError as e:
if e.errno != errno.ECONNRESET:
raise # Not error we are looking for
pass # Handle error here.
You can also use shift()
.
var streetaddress = addy.split(',').shift();
According to MDN Web Docs:
The
shift()
method removes the first element from an array and returns that removed element. This method changes the length of the array.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/shift
jboss and glassfish include a servlet container(like tomcat), however the two application servers (jboss and glassfish) also provide a bean container (and a few other things aswell I imagine)
Simply don't put whole commands in variables. You'll get into a lot of trouble trying to recover quoted arguments.
Also:
#! /bin/bash
if [ $# -ne 2 ]
then
echo "Usage: $(basename $0) DIRECTORY BACKUP_DIRECTORY"
exit 1
fi
directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"
tar cv "$directory" | openssl des3 -salt | split -b 1024m - "$backup_file"
Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if
block.
public String foo(@Nullable String mayBeNothing) {
return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}
You can also throw some exception in there by swapping .orElse
to
orElseThrow(() -> new Exception("Dont' send a null"))
.
If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe...
so your intention is clear.
I was getting this problem with a maven project using the eclipse IDE. I changed the 'Order and Export' in the project's build path putting the Maven dependencies first and the error disappeared. I guess it's because the eclipse IDE was initially building my application source before loading the Maven libraries.
mysqli_error()
As in:
$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);
Trigger error is better than die because you can use it for development AND production, it's the permanent solution.
Symbolic or soft link (files or directories, more flexible and self documenting)
# Source Link
ln -s /home/jake/doc/test/2000/something /home/jake/xxx
Hard link (files only, less flexible and not self documenting)
# Source Link
ln /home/jake/doc/test/2000/something /home/jake/xxx
More information: man ln
/home/jake/xxx
is like a new directory. To avoid "is not a directory: No such file or directory" error, as @trlkly comment, use relative path in the target, that is, using the example:
cd /home/jake/
ln -s /home/jake/doc/test/2000/something xxx
1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math
2: Yes: But you already know it:
`^`(x,y)
#[1] 1024
In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math
.
Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply
and sapply
:
> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )

The version number above of course refers to the major version of your Visual studio you see in the about box, not to the year in the name. A thorough list can be found here. Starting recently, Visual Studio will start updating its ranges monotonically, meaning you should check ranges, rather than exact compiler values.
cl.exe /?
will give a hint of the used version, e.g.:
c:\program files (x86)\microsoft visual studio 11.0\vc\bin>cl /?
Microsoft (R) C/C++ Optimizing Compiler Version 17.00.50727.1 for x86

If you're happy you know what you're doing and can accept the portability problems, on GCC for example you can disable the warning on the command line:

I use this for my own apps to work with AVI and MP4 file headers for similar reasons to you.
You could use a function similar to this also, it would allow you to add in different cases where you would like to change values:
Public Function strReplace(varValue As Variant) as Variant
Select Case varValue
Case "Avenue"
strReplace = "Ave"
Case "North"
strReplace = "N"
Case Else
strReplace = varValue
End Select
End Function
Then your SQL would read something like:
SELECT strReplace(Address) As Add FROM Tablename
Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.
Create /etc/nginx/sites-available
and /etc/nginx/sites-enabled
and then edit the http
block inside /etc/nginx/nginx.conf
and add this line
include /etc/nginx/sites-enabled/*;
Of course, all the files will be inside sites-available
, and you'd create a symlink for them inside sites-enabled
for those you want enabled.
I have been reading about Android Service very recently and got a chance to deep dive on it. I have encountered a service leak, for my situation it happened because I had an unbound Service which was starting a bound Service, but in this my unbound Service is replaced by an Activity.
So when I was stopping my unbound Service by using stopSelf() the leak occurred, the reason was I was stopping the parent service without unbinding the bound service. Now the bound service is running and it doesn't know to whom does it belong.
The easy and straight forward fix is you should call unbindService(YOUR_SERVICE); in your onDestroy() function of your parent Activity/Service. This way the lifecycle will ensure that your bound services are stopped or cleaned up before your parent Activity/Services go down.
There is one other variation of this problem. Sometimes in your bound service you want certain functions to work only if the service is bound so we end up putting a bound flag in the onServiceConnected like:
public void onServiceConnected(ComponentName name, IBinder service) {
bounded = true;
// code here
}
This works fine till here but the problem comes when we treat onServiceDisconnected function as a callback for unbindService function call, this by documentation is only called when a service is killed or crashed. And you will never get this callback in the same thread. Hence, we end up doing something like:
public void onServiceDisconnected(ComponentName name) {
bounded = false;
}
Which creates major bug in the code because our bound flag never gets reset to false and when this service is connected back again most of the times it is true
. So in order to avoid this scenario you should set the bound
to false the moment you are calling unbindService
.
This is cover in more detail in Erik's blog.
Hope who ever came here got his curiosity satisfied.
If you are using the two formulas at the same time, it will not work... Here is a simple spreadsheet with it working: https://docs.google.com/spreadsheet/ccc?key=0AiOy0YDBXjt4dDJSQWg1Qlp6TEw5SzNqZENGOWgwbGc If you are still getting problems I would need to know what type of erroneous result you are getting.
Today() returns a numeric integer value: Returns the current computer system date. The value is updated when your document recalculates. TODAY is a function without arguments.
Apart from Install Shield and WiX, there is Inno Setup. Although I haven't tried it myself I have heard good things about it.
This is a textbook case for a constructor function:
var myArray = [];
function myElement(id, value){
this.id = id
this.value = value
}
myArray[0] = new myElement(0,1)
myArray[1] = new myElement(2,3)
// or myArray.push(new myElement(1, 1))
Since API 14 you can use the function onTrimMemory()
and check for the flag TRIM_MEMORY_UI_HIDDEN
. This will tell you that your Application is going to the background.
So in your custom Application class you can write something like:
override fun onTrimMemory(level: Int) {
if (level == TRIM_MEMORY_UI_HIDDEN) {
// Application going to background, do something
}
}
For an in-depth study of this, I invite you to read this article: http://www.developerphil.com/no-you-can-not-override-the-home-button-but-you-dont-have-to/
Googling gives me this:
Command A & Command B
Execute Command A, then execute Command B (no evaluation of anything)
Command A | Command B
Execute Command A, and redirect all its output into the input of Command B
Command A && Command B
Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B
Command A || Command B
Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B
format
supports a percentage floating point precision type:
>>> print "{0:.0%}".format(1./3)
33%
If you don't want integer division, you can import Python3's division from __future__
:
>>> from __future__ import division
>>> 1 / 3
0.3333333333333333
# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%
# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%
You are accessing the list elements and then using them to attempt to index your list. This is not a good idea. You already have an answer showing how you could use indexing to get your sum list, but another option would be to zip
the list with a slice of itself such that you can sum the pairs.
b = [i + j for i, j in zip(a, a[1:])]
You can simply add another join like this:
SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data
INNER JOIN dashboard_messages
ON dashboard_message_id = dashboard_messages.id
INNER JOIN images
ON dashboard_messages.image_id = images.image_id
However be aware that, because it is an INNER JOIN
, if you have a message without an image, the entire row will be skipped. If this is a possibility, you may want to do a LEFT OUTER JOIN
which will return all your dashboard messages and an image_filename only if one exists (otherwise you'll get a null)
SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data
INNER JOIN dashboard_messages
ON dashboard_message_id = dashboard_messages.id
LEFT OUTER JOIN images
ON dashboard_messages.image_id = images.image_id
os.system('command')
returns a 16 bit number, which first 8 bits from left(lsb) talks about signal used by os to close the command, Next 8 bits talks about return code of command.
Refer my answer for more detail in What is the return value of os.system() in Python?
In WPF, you use a DispatcherTimer
.
System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();
private void dispatcherTimer_Tick(object sender, EventArgs e)
{
// code goes here

I just noticed that top is available in adb, so you can do things like
adb shell
top -m 5
to monitor the top five CPU hogging processes.
Or
adb shell top -m 5 -s cpu -n 20 |tee top.log
to record this for one minute and collect the output to a file on your computer.
The PHP refresh after 5 seconds didn't work for me when opening a Save As dialogue to save a file: (header('Content-type: text/plain'); header("Content-Disposition: attachment; filename=$filename>");)
After the Save As link was clicked, and file was saved, the timed refresh stopped on the calling page.
However, thank you very much, ibu's javascript solution just kept on ticking and refreshing my webpage, which is what I needed for my specific application. So thank you ibu for posting javascript solution to php problem here.
You can use javascript to redirect after some time
setTimeout(function () {
window.location.href = 'http://www.google.com';
},5000); // 5 seconds
In sake of readability it should be something like
<?php
$countries = $myaddress->get_countries();
foreach($countries as $value) {
$selected ='';
if($value=='United States') $selected ='selected="selected"';
echo '<option value="'.$value.'"'.$selected.'>'.$value.'</option>';
}
?>
desire to stuff EVERYTHING in a single line is a decease, man. Write distinctly.
But there is another way, a better one. There is no need to use echo at all. Learn to use templates. Prepare your data first, and display it only then ready.
Business logic part:
$countries = $myaddress->get_countries();
$selected_country = 1;
Template part:
<? foreach($countries as $row): ?>
<option value="<?=$row['id']?>"<? if ($row['id']==$current_country):> "selected"><? endif ?>
<?=$row['name']?>
</option>
<? endforeach ?>
Here's a way to do it using only standard String functions and no explicit loops:
// create a string made up of n copies of s
repeated = String.format(String.format("%%%ds", n), " ").replace(" ",s);
Try something like this:
type: application/ms-excel
/**
* used to get file from server
*/
this.http.get(`${environment.apiUrl}`,{
responseType: 'arraybuffer',headers:headers}
).subscribe(response => this.downLoadFile(response, "application/ms-excel"));
/**
* Method is use to download file.
* @param data - Array Buffer data
* @param type - type of the document.
*/
downLoadFile(data: any, type: string) {
let blob = new Blob([data], { type: type});
let url = window.URL.createObjectURL(blob);
let pwa = window.open(url);
if (!pwa || pwa.closed || typeof pwa.closed == 'undefined') {
alert( 'Please disable your Pop-up blocker and try again.');
}
}
Finally, I found the solution to my problem.
I looked into the Magento system log file (var/log/system.log). There I saw the exact error.
The error is as below:-
Recoverable Error: Argument 1 passed to Mage_Core_Model_Store::setWebsite() must be an instance of Mage_Core_Model_Website, null given, called in YOUR_PATH\app\code\core\Mage\Core\Model\App.php on line 555 and defined in YOUR_PATH\app\code\core\Mage\Core\Model\Store.php on line 285
Recoverable Error: Argument 1 passed to Mage_Core_Model_Store_Group::setWebsite() must be an instance of Mage_Core_Model_Website, null given, called in YOUR_PATH\app\code\core\Mage\Core\Model\App.php on line 575 and defined in YOUR_PATH\app\code\core\Mage\Core\Model\Store\Group.php on line 227
Actually, I had this error before. But, error display message like Error: 404 Not Found
was new to me.
The reason for this error is that store_id
and website_id
for admin should be set to 0 (zero). But, when you import database to new server, somehow these values are not set to 0.
Open PhpMyAdmin and run the following query in your database:-
SET FOREIGN_KEY_CHECKS=0;

They do very different things.
The below checks if A has anything except the values False
, []
, None
, ''
and 0
. It checks the value of A.
if A:
The below checks if A is a different object than None. It checks and compares the reference (memory address) of A and None.
if A is not None:
UPDATE: Further explanation
Many times the two seem to do the same thing so a lot of people use them interchangeably. The reason the two give the same results is many times by pure coincidence due to optimizations of the interpreter/compiler like interning or something else.
With those optimizations in mind, integers and strings of the same value end up using the same memory space. That probably explains why two separate strings act as if they are the same.
> a = 'test'
> b = 'test'
> a is b
True
> a == b
True
Other things don't behave the same though..
> a = []
> b = []
> a is b
False
> a == b
True
The two lists clearly have their own memory. Surprisingly tuples behave like strings.
> a = ()
> b = ()
> a is b
True
> a == b
True
Probably this is because tuples are guaranteed to not change, thus it makes sense to reuse the same memory.
This shows that you should be extra vigilant on what comparison operator you use. Use is
and ==
depending on what you really want to check. These things can be hard to debug since is
reads like prose that we often just skim over it.
Sample Usage:
import paramiko
paramiko.util.log_to_file("paramiko.log")
# Open a transport
host,port = "example.com",22
transport = paramiko.Transport((host,port))
# Auth
username,password = "bar","foo"
transport.connect(None,username,password)
# Go!
sftp = paramiko.SFTPClient.from_transport(transport)
# Download
filepath = "/etc/passwd"
localpath = "/home/remotepasswd"
sftp.get(filepath,localpath)
# Upload
filepath = "/home/foo.jpg"
localpath = "/home/pony.jpg"
sftp.put(localpath,filepath)
# Close
if sftp: sftp.close()
if transport: transport.close()
This problem was driving me crazy too. I was using PHP on my server side so I was not able to use @The Lazy Log(ruby) & @deweydb(python) solutions. However it pointed me to the right direction. I fixed it on the backed using Imagick's getImageOrientation().
<?php
// Note: $image is an Imagick object, not a filename! See example use below.
function autoRotateImage($image) {
$orientation = $image->getImageOrientation();
switch($orientation) {
case imagick::ORIENTATION_BOTTOMRIGHT:
$image->rotateimage("#000", 180); // rotate 180 degrees
break;
case imagick::ORIENTATION_RIGHTTOP:
$image->rotateimage("#000", 90); // rotate 90 degrees CW
break;
case imagick::ORIENTATION_LEFTBOTTOM:
$image->rotateimage("#000", -90); // rotate 90 degrees CCW
break;
}
// Now that it's auto-rotated, make sure the EXIF data is correct in case the EXIF gets saved with the image!
$image->setImageOrientation(imagick::ORIENTATION_TOPLEFT);
}
?>

Without access to the type (and no "InternalsVisibleTo" etc) you would have to use reflection. But a better question would be: should you be accessing this data? It isn't part of the public type contract... it sounds to me like it is intended to be treated as an opaque object (for their purposes, not yours).
You've described it as a public instance field; to get this via reflection:
object obj = ...
string value = (string)obj.GetType().GetField("test").GetValue(obj);
If it is actually a property (not a field):
string value = (string)obj.GetType().GetProperty("test").GetValue(obj,null);
If it is non-public, you'll need to use the BindingFlags
overload of GetField
/GetProperty
.
Important aside: be careful with reflection like this; the implementation could change in the next version (breaking your code), or it could be obfuscated (breaking your code), or you might not have enough "trust" (breaking your code). Are you spotting the pattern?
The /P
switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.
Two ways I've used it... first:
SET /P variable=
When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.
And second:
SET /P variable=<%temp%\filename.txt
Will set variable to contents (the first line) of the txt file. This method won't work unless the /P
is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

Sometimes, XCode does not forget the line which had an "Editor Placeholder" even if you have replaced it with a value. Cut the portion of the code where XCode is complaining and paste the code back to the same place to make the error message go away. This worked for me.
Acrylic DNS Proxy (free, open source) does the job. It creates a proxy DNS server (on your own computer) with its own hosts file. The hosts file accepts wildcards.
Download from the offical website
http://mayakron.altervista.org/support/browse.php?path=Acrylic&name=Home
To configure Acrylic DNS Proxy, install it from the above link then go to:
Add the folowing lines on the end of the file:
127.0.0.1 *.localhost
127.0.0.1 *.local
127.0.0.1 *.lc
Restart the Acrylic DNS Proxy service:
You will also need to adjust your DNS setting in you network interface settings:
Set "Use the following DNS server address":
Preferred DNS Server: 127.0.0.1
If you then combine this answer with jeremyasnyder's answer (using VirtualDocumentRoot
) you can then automatically setup domains/virtual hosts by simply creating a directory.
Simply putting - this.setState({data: value}) is asynchronous in nature that means it moves out of the Call Stack and only comes back to the Call Stack unless it is resolved.
Please read about Event Loop to have a clear picture about Asynchronous nature in JS and why it takes time to update -
https://medium.com/front-end-weekly/javascript-event-loop-explained-4cd26af121d4
Hence -
this.setState({data:value});
console.log(this.state.data); // will give undefined or unupdated value
as it takes time to update. To achieve the above process -
this.setState({data:value},function () {
console.log(this.state.data);
});
The JavaScript function:
String.prototype.capitalize = function(){
return this.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
};
To use this function:
capitalizedString = someString.toLowerCase().capitalize();
Also, this would work on multiple words string.
To make sure the converted City name is injected into the database, lowercased and first letter capitalized, then you would need to use JavaScript before you send it over to server side. CSS simply styles, but the actual data would remain pre-styled. Take a look at this jsfiddle example and compare the alert message vs the styled output.
If you really want one line per user, you can group by grantee (require PG9+ for string_agg)
SELECT grantee, string_agg(privilege_type, ', ') AS privileges
FROM information_schema.role_table_grants
WHERE table_name='mytable'
GROUP BY grantee;
This should output something like :
grantee | privileges
---------+----------------
user1 | INSERT, SELECT
user2 | UPDATE
(2 rows)
You need to read from req.Body
. The ParseForm
method is reading from the req.Body
and then parsing it in standard HTTP encoded format. What you want is to read the body and parse it in JSON format.
Here's your code updated.
package main
import (
"encoding/json"
"log"
"net/http"
"io/ioutil"
)
type test_struct struct {
Test string
}
func test(rw http.ResponseWriter, req *http.Request) {
body, err := ioutil.ReadAll(req.Body)
if err != nil {
panic(err)
}
log.Println(string(body))
var t test_struct
err = json.Unmarshal(body, &t)
if err != nil {
panic(err)
}
log.Println(t.Test)
}
func main() {
http.HandleFunc("/test", test)
log.Fatal(http.ListenAndServe(":8082", nil))
}
Encountering the same problem, I solved this by reconverting the file with default mp4 settings in iMovie.
Your code works, but the fadeIn
doesn't, because it's already visible. I think the effect you want to achieve is: fadeOut
→ load
→ fadeIn
:
var auto_refresh = setInterval(function () {
$('.View').fadeOut('slow', function() {
$(this).load('/echo/json/', function() {
$(this).fadeIn('slow');
});
});
}, 15000); // refresh every 15000 milliseconds
Try it here: http://jsfiddle.net/kelunik/3qfNn/1/
Additional notice: As Khanh TO mentioned, you may need to get rid of the browser's internal cache. You can do so using $.ajax
and $.ajaxSetup ({ cache: false });
or the random-hack, he mentioned.
I found a free plugin that can generate class diagrams with android studio. It's called SimpleUML.
Update Android Studio 2.2+: To install the plugin, follow steps in this answer: https://stackoverflow.com/a/36823007/1245894
Older version of Android Studio
On Mac: go to Android Studio
-> Preferences
-> Plugins
On Windows: go to Android Studio
-> File
-> Settings
-> Plugins
Click on Browse repositories...
and search for SimpleUMLCE
(CE means Community Edition, this is what android studio is based on).
Install it, restart, then you can do a right click on the folder containing the classes you want to visualize, and select Add to simpleUML Diagram
.
That's it; you have you fancy class diagram generated from your code!
Simple solution: just create and add a second, non-generic interface to the generic class:
public interface IGenericClass
{
}
public class GenericClass<T> : GenericInterface<T>, IGenericClass
{
}
Then just check for that in any way you like using is
, as
, IsAssignableFrom
, etc.
if (thing is IGenericClass)
{
// Do work
{
Obviously only possible if you have the ability to edit the generic class (which the OP seems to have), but it's a bit more elegant and readable than using a cryptic extension method.
You have to convert the pivot to values first before you can do that:
Are you using Google App Engine? You could use cookies (made with JavaScript) to maintain a relationship between filenames and the name received from the server.
Regarding 3rd definition:
var foo = function foo() { return 5; }
Heres an example which shows how to use possibility of recursive call:
a = function b(i) {
if (i>10) {
return i;
}
else {
return b(++i);
}
}
console.log(a(5)); // outputs 11
console.log(a(10)); // outputs 11
console.log(a(11)); // outputs 11
console.log(a(15)); // outputs 15
Edit: more interesting example with closures:
a = function(c) {
return function b(i){
if (i>c) {
return i;
}
return b(++i);
}
}
d = a(5);
console.log(d(3)); // outputs 6
console.log(d(8)); // outputs 8
See the port and make a port change in postgresql.conf. My installation of postgres 9.4 uses port 5431 or 5434 instead of 5432. If it say the port is in use so change the port. And check if you give password in psql installation so give the password in file and save it.
[Ljava.lang.Object;
is the name for Object[].class
, the java.lang.Class
representing the class of array of Object
.
The naming scheme is documented in Class.getName()
:
If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).
If this class object represents a primitive type or
void
, then the name returned is the Java language keyword corresponding to the primitive type orvoid
.If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more
'['
characters representing the depth of the array nesting. The encoding of element type names is as follows:Element Type Encoding boolean Z byte B char C double D float F int I long J short S class or interface Lclassname;
Yours is the last on that list. Here are some examples:
// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx
The reason why the toString()
method on arrays returns String
in this format is because arrays do not @Override
the method inherited from Object
, which is specified as follows:
The
toString
method for classObject
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:getClass().getName() + '@' + Integer.toHexString(hashCode())
Note: you can not rely on the toString()
of any arbitrary object to follow the above specification, since they can (and usually do) @Override
it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass()
on it (a final
method inherited from Object
) and then reflecting on the returned Class
object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).
toString
for arraysjava.util.Arrays
provides toString
overloads for primitive arrays and Object[]
. There is also deepToString
that you may want to use for nested arrays.
Here are some examples:
int[] nums = { 1, 2, 3 };
System.out.println(nums);
// [I@xxxxx
System.out.println(Arrays.toString(nums));
// [1, 2, 3]
int[][] table = {
{ 1, },
{ 2, 3, },
{ 4, 5, 6, },
};
System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]
System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]
There are also Arrays.equals
and Arrays.deepEquals
that perform array equality comparison by their elements, among many other array-related utility methods.
The other answer is very complete, but here is a rule of thumb:
call
is blocking:
call('notepad.exe')
print('hello') # only executed when notepad is closed
Popen
is non-blocking:
Popen('notepad.exe')
print('hello') # immediately executed
As with SQL Server 2012, you can use the built-in format function:
SELECT FORMAT(Minutes/60.0, 'N2')
(just for further readings...)
As the answer by @plaul mentions TouchableOpacity
, here is an example of how you can use that;
<TouchableOpacity
style={someStyles}
onPress={doSomething}
>
<Text>Press Here</Text>
</TouchableOpacity>
just override onCreateOptionsMenu like this in your MainPage.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
For browser compatibility you can use this code. This method returns browser name and version :
private string GetBrowserNameWithVersion
{
var userAgent = Request.UserAgent;
var browserWithVersion = "";
if (userAgent.IndexOf("Edge") > -1)
{
//Edge
browserWithVersion = "Edge Browser Version : " + userAgent.Split(new string[] { "Edge/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Chrome") > -1)
{
//Chrome
browserWithVersion = "Chrome Browser Version : " + userAgent.Split(new string[] { "Chrome/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Safari") > -1)
{
//Safari
browserWithVersion = "Safari Browser Version : " + userAgent.Split(new string[] { "Safari/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Firefox") > -1)
{
//Firefox
browserWithVersion = "Firefox Browser Version : " + userAgent.Split(new string[] { "Firefox/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("rv") > -1)
{
//IE11
browserWithVersion = "Internet Explorer Browser Version : " + userAgent.Split(new string[] { "rv:" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("MSIE") > -1)
{
//IE6-10
browserWithVersion = "Internet Explorer Browser Version : " + userAgent.Split(new string[] { "MSIE" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Other") > -1)
{
//Other
browserWithVersion = "Other Browser Version : " + userAgent.Split(new string[] { "Other" }, StringSplitOptions.None)[1].Split('.')[0];
}
return browserWithVersion;
}
I use the following code to test the empty line with or without white spaces.
if len(line.strip()) == 0 :
# do something with empty line
If you are limited to ES6, the best option is Promise all. Promise.all(array)
also returns an array of promises after successfully executing all the promises in array
argument.
Suppose, if you want to update many student records in the database, the following code demonstrates the concept of Promise.all in such case-
let promises = students.map((student, index) => {
//where students is a db object
student.rollNo = index + 1;
student.city = 'City Name';
//Update whatever information on student you want
return student.save();
});
Promise.all(promises).then(() => {
//All the save queries will be executed when .then is executed
//You can do further operations here after as all update operations are completed now
});
Map is just an example method for loop. You can also use for
or forin
or forEach
loop. So the concept is pretty simple, start the loop in which you want to do bulk async operations. Push every such async operation statement in an array declared outside the scope of that loop. After the loop completes, execute the Promise all statement with the prepared array of such queries/promises as argument.
The basic concept is that the javascript loop is synchronous whereas database call is async and we use push method in loop that is also sync. So, the problem of asynchronous behavior doesn't occur inside the loop.
You can easily achieve this with the use of jQuery .toggle().
$("#btnDisplay").click(function() {
$("#div1").toggle();
$("#div2").toggle();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div1">
First Div
</div>
<div id="div2" style="display: none;">
Second Div
</div>
<button id="btnDisplay">Display</button>
In Android Studio 2.1 I follow the this way,
Goto app -> src-> main -> assets folder (If not available create it) -> put your JAR files
In your build.gradle add dependency like this,
implementation files('src/main/assets/jsoup.jar')
implementation files('src/main/assets/org-apache-xmlrpc.jar')
implementation files('src/main/assets/org.apache.commons.httpclient.jar')
implementation files('src/main/assets/ws-commons-util-1.0.2.jar')
Sync now. Now your JAR files ready to use.
in my case
my service has function to Upload Files
and this error just shown up on trying to upload Big Files
so I found this answer to Increase maxRequestLength
to needed value in web.config
and problem solved
if you don't make any upload or download operations maybe this answer will not help you
function currentUrl() {
$protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') === FALSE ? 'http' : 'https';
$host = $_SERVER['HTTP_HOST'];
$script = $_SERVER['SCRIPT_NAME'];
$params = $_SERVER['QUERY_STRING'];
return $protocol . '://' . $host . $script . '?' . $params;
}
Then add your value with something like;
echo currentUrl().'&value=myVal';
You can use the .forEach() method of JavaScript for looping through JSON.
var datesBooking = [_x000D_
{"date": "04\/24\/2018"},_x000D_
{"date": "04\/25\/2018"}_x000D_
];_x000D_
_x000D_
datesBooking.forEach(function(data, index) {_x000D_
console.log(data);_x000D_
});
_x000D_
The two have different semantics when it comes to the key already existing in the map. So they aren't really directly comparable.
But the operator[] version requires default constructing the value, and then assigning, so if this is more expensive then copy construction, then it will be more expensive. Sometimes default construction doesn't make sense, and then it would be impossible to use the operator[] version.
It's a bit late but I just had the same problem and finally solved it with the help of another stackoverflow post (https://stackoverflow.com/a/29103071).
img {
object-fit: cover;
width: 50px;
height: 100px;
}
Hope this still helps somebody.
Ps: Also works together with max-height, max-width, min-width and min-height css properties. It's espacially handy with using lenght units like 100% or 100vh/100vw to fill the container or the whole browser window.
If you want a lighter footprint, but a longer script, get the elements innerHTML and only create and clone the empty parent-
function getHTML(who,lines){
if(!who || !who.tagName) return '';
var txt, ax, str, el= document.createElement('div');
el.appendChild(who.cloneNode(false));
txt= el.innerHTML;
ax= txt.indexOf('>')+1;
str= txt.substring(0, ax)+who.innerHTML+ txt.substring(ax);
el= null;
return lines? str.replace(/> *</g,'>\n<'): str;
//easier to read if elements are separated
}
When i use these solution this error coming:
java -jar xxxxx.jar
no main manifest attribute, in xxxxx.jar
and solution is:
You have to change manifest directory:
<project folder>\src\main\java
change java to resources
<project folder>\src\main\resources

I definitely agree that this is perfect for an extension method, but I think it can be improved a bit.
public static string Remove(this string source, string remove, int firstN)
{
if(firstN <= 0 || string.IsNullOrEmpty(source) || string.IsNullOrEmpty(remove))
{
return source;
}
int index = source.IndexOf(remove);
return index < 0 ? source : source.Remove(index, remove.Length).Remove(remove, --firstN);
}
This does a bit of recursion which is always fun.
Here is a simple unit test as well:
[TestMethod()]
public void RemoveTwiceTest()
{
string source = "look up look up look it up";
string remove = "look";
int firstN = 2;
string expected = " up up look it up";
string actual;
actual = source.Remove(remove, firstN);
Assert.AreEqual(expected, actual);
}
You have to use ==
to compare (or even ===
, if you want to compare types). A single =
is for assignment.
if (one == 'rock' && two == 'rock') {
console.log('Tie! Try again!');
}
Reason for error:
The query from p in dc.BlogPosts where p.BlogPostID == ID select p
returns a sequence.
Single()
tries to retrieve an element from the sequence returned in step1.
As per the exception - The sequence returned in step1 contains no elements.
Single() tries to retrieve an element from the sequence returned in step1 which contains no elements.
Since Single()
is not able to fetch a single element from the sequence returned in step1, it throws an error.
Fix:
Make sure the query (from p in dc.BlogPosts where p.BlogPostID == ID select p)
returns a sequence with at least one element.
ORDER BY
is always last...
However, you need to pick the fields you ACTUALLY WANT then select only those and group by them. SELECT *
and GROUP BY Email
will give you RANDOM VALUES for all the fields but Email
. Most RDBMS will not even allow you to do this because of the issues it creates, but MySQL is the exception.
SELECT Email, COUNT(*)
FROM user_log
GROUP BY Email
HAVING COUNT(*) > 1
ORDER BY UpdateDate DESC

I hit the same issue and none of the solutions worked. I then bumped an answer in stackexchange dba which lead to this link. So here is what I did:
sudo mysqld_safe --skip-grant-tables --skip-networking &
sudo mysql -uroot
and got into mysql consoleALTER USER root@localhost identified via unix_socket;
and flush privileges;
consecutively to allow for password-less loginIf you want to set the password then you need to do one more step, that is running ALTER USER root@localhost IDENTIFIED VIA mysql_native_password;
and SET PASSWORD = PASSWORD('YourPasswordHere');
consecutively.
UPDATE
Faced this issue recently and here is how I resolved it with recent version, but before that some background. Mariadb does not require a password when is run as root. So first run it as a root. Then once in the Mariadb console, change password there. If you are content with running it as admin, you can just keep doing it but I find that cumbersome especially because I cannot use that with DB Admin Tools. TL;DR here is how I did it on Mac (should be similar for *nix systems)
sudo mariadb-secure-installation
then follow instructions on the screen!
Hope this will help someone and serve me a reference for future problems
I found 2 quick options to fix this:
Happy coding!
Omit row if either of two specific columns contain <NA>
.
DF[!is.na(DF$x)&!is.na(DF$z),]
Using the Google Maps API V3, create a Circle object, then use bindTo() to tie it to the position of your Marker (since they are both google.maps.MVCObject instances).
// Create marker
var marker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(53, -2.5),
title: 'Some location'
});
// Add circle overlay and bind to marker
var circle = new google.maps.Circle({
map: map,
radius: 16093, // 10 miles in metres
fillColor: '#AA0000'
});
circle.bindTo('center', marker, 'position');
You can make it look just like the Google Latitude circle by changing the fillColor, strokeColor, strokeWeight etc (full API).

Even without cloning or fetching, you can check the list of tags on the upstream repo with git ls-remote
:
git ls-remote --tags /url/to/upstream/repo
(as illustrated in "When listing git-ls-remote why there's “^{}
” after the tag name?")
xbmono illustrates in the comments that quotes are needed:
git ls-remote --tags /some/url/to/repo "refs/tags/MyTag^{}"
Note that you can always push your commits and tags in one command with (git 1.8.3+, April 2013):
git push --follow-tags
See Push git commits & tags simultaneously.
Regarding Atlassian SourceTree specifically:
Note that, from this thread, SourceTree ONLY shows local tags.
There is an RFE (Request for Enhancement) logged in SRCTREEWIN-4015
since Dec. 2015.
A simple workaround:
see a list of only unpushed tags?
git push --tags
or check the "
Push all tags
" box on the "Push" dialog box, all tags will be pushed to your remote.
That way, you will be "sure that they are present in remote so that other developers can pull them".
First I would recommend you to store your timestamp as a NSNumber
in your Firebase Database, instead of storing it as a String
.
Another thing worth mentioning here, is that if you want to manipulate dates with Swift, you'd better use Date
instead of NSDate
, except if you're interacting with some Obj-C code in your app.
You can of course use both, but the Documentation states:
Date bridges to the NSDate class. You can use these interchangeably in code that interacts with Objective-C APIs.
Now to answer your question, I think the problem here is because of the timezone.
For example if you print(Date())
, as for now, you would get:
2017-09-23 06:59:34 +0000
This is the Greenwich Mean Time (GMT).
So depending on where you are located (or where your users are located) you need to adjust the timezone before (or after, when you try to access the data for example) storing your Date
:
let now = Date()
let formatter = DateFormatter()
formatter.timeZone = TimeZone.current
formatter.dateFormat = "yyyy-MM-dd HH:mm"
let dateString = formatter.string(from: now)
Then you have your properly formatted String
, reflecting the current time at your location, and you're free to do whatever you want with it :) (convert it to a Date
/ NSNumber
, or store it directly as a String
in the database..)
You can use OLD
and NEW
in the trigger to access those values which had changed in that trigger. Mysql Ref
1-liner, takes a XML string text
and YourType
as the expected object type. not very different from other answers, just compressed to 1 line:
var result = (YourType)new XmlSerializer(typeof(YourType)).Deserialize(new StringReader(text));
Tomcat can work in 2 modes:
Tomcat 7 is BIO by default, although consensus seems to be "don't use Bio because Nio is better in every way". You set this using the protocol
parameter in the server.xml
file.
HTTP/1.1
or org.apache.coyote.http11.Http11Protocol
org.apache.coyote.http11.Http11NioProtocol
If you're using BIO then I believe they should be more or less the same.
If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. The defaults are maxConnections=10,000 and maxThreads=200. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.
public byte[] longToBytes(long x) {
ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
buffer.putLong(x);
return buffer.array();
}
public long bytesToLong(byte[] bytes) {
ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
buffer.put(bytes);
buffer.flip();//need flip
return buffer.getLong();
}
Or wrapped in a class to avoid repeatedly creating ByteBuffers:
public class ByteUtils {
private static ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
public static byte[] longToBytes(long x) {
buffer.putLong(0, x);
return buffer.array();
}
public static long bytesToLong(byte[] bytes) {
buffer.put(bytes, 0, bytes.length);
buffer.flip();//need flip
return buffer.getLong();
}
}
Since this is getting so popular, I just want to mention that I think you're better off using a library like Guava in the vast majority of cases. And if you have some strange opposition to libraries, you should probably consider this answer first for native java solutions. I think the main thing my answer really has going for it is that you don't have to worry about the endian-ness of the system yourself.
This snippet works in IE7 at least

right: 0;
}
</style>
</head>
<body>
<div id="foo">Hello World</div>

Perhaps the default

<html>
<div>Hello {{name|default:"World"}}!</div>

Here is an update for Swift 3 and an addition to Mani's answer. I would suggest using sender.view
in combination with tagging UIViews (or other elements, depending on what you are trying to track) for a somewhat more "advanced" approach.
let yourTapEvent = UITapGestureRecognizer(target: self, action: #selector(yourController.yourFunction))
yourObject.addGestureRecognizer(yourTapEvent) // adding the gesture to your object
Defining the function in the same testController (that's the name of your View Controller). We are going to use tags here - tags are Int IDs, which you can add to your UIView with yourButton.tag = 1
. If you have a dynamic list of elements like an array you can make a for-loop, which iterates through your array and adds a tag, which increases incrementally
func yourFunction(_ sender: AnyObject) {
let yourTag = sender.view!.tag // this is the tag of your gesture's object
// do whatever you want from here :) e.g. if you have an array of buttons instead of just 1:
for button in buttonsArray {
if(button.tag == yourTag) {
// do something with your button
}
}
}
The reason for all of this is because you cannot pass further arguments for yourFunction when using it in conjunction with #selector.
If you have an even more complex UI structure and you want to get the parent's tag of the item attached to your tap gesture you can use let yourAdvancedTag = sender.view!.superview?.tag
e.g. getting the UIView's tag of a pressed button inside that UIView; can be useful for thumbnail+button lists etc.
You need to open the file first. This doesn't work:
json_file = json.load('test.json')
But this works:
f = open('test.json')
json_file = json.load(f)
To the base question, the following will do the trick (hiding the taskbar)
private void Form1_Load(object sender, EventArgs e)
{
this.TopMost = true;
this.FormBorderStyle = FormBorderStyle.None;
this.WindowState = FormWindowState.Maximized;
}
But, interestingly, if you swap those last two lines the Taskbar remains visible. I think the sequence of these actions will be hard to control with the properties window.
You can also do just like this:
Task.Run(() => this.FunctionAsync()).Wait();
Note: Be careful about thread blocking!
I struggled with this error for more than an hour! Below is what helped me resolve it. All this while my working directory was the repo i had cloned on my system.
If you are doing adding files to your existing repository** 1. I pulled everything which I had added to my repository to my GitHub folder:
git pull
Output was- some readme file file1 file2
eg. some readme file file1 file2 newfile1 newfile2
git add "newfile1" "newfile2"
[optional] git status this will assure you if the files you want to add are staged properly or not output was
On branch master Your branch is up-to-date with 'origin/master'. Changes to be committed: (use "git reset HEAD ..." to unstage)
new file: newfile1
new file: newfile2
5.git commit -m "whatever description you want to give" 6.git push
And all my new files along with the older ones were seen in my repo.
Pure CSS approaches that work very well are discussed here. Two techniques are examined in particular and I personally prefer the second as it not CSS3 dependent, which suits my own needs better.
If most/all of your traffic has a CSS3 capable browser, the first method is quicker and cleaner to implement (copy/pasted by Mr. Zoidberg in another answer here for convenience, though I'd visit the source for further background on why it works).
An alternative method to CSS is to use the JavaScript library jQuery to detect resolution changes and adjust the image size accordingly. This article covers the jQuery technique and provides a live demo.
Supersized is a dedicated JavaScript library designed for static full screen images as well as full sized slideshows.
A good tip for full-screen images is to scale them with a correct ratio beforehand. I normally aim for a size of 1500x1000 when using supersized.js or 1680x1050 for other methods, setting the jpg quality for photographs to between 60-80% resulting in a file size in the region of 100kb or less if possible without compromising quality too much.
You're not looping over the items. Try this instead:
$.getJSON(url, function(data){
$.each(data.response.venue.tips.groups.items, function (index, value) {
console.log(this.text);
});
});
Use Collections.synchronizedList()
.
Ex:
Collections.synchronizedList(new ArrayList<YourClassNameHere>())
$data
is indeed an array, but it's made up of objects.
Convert its content to array before creating it:
$data = array();
foreach ($results as $result) {
$result->filed1 = 'some modification';
$result->filed2 = 'some modification2';
$data[] = (array)$result;
#or first convert it and then change its properties using
#an array syntax, it's up to you
}
Excel::create(....
You can't concatenate an int to a string. Instead of:
SET @sql = N'DECLARE @Rt int; SET @Rt = ' + @RowTo;
You need:
SET @sql = N'DECLARE @Rt int; SET @Rt = ' + CONVERT(VARCHAR(12), @RowTo);
To help illustrate what's happening here. Let's say @RowTo = 5.
DECLARE @RowTo int;
SET @RowTo = 5;
DECLARE @sql nvarchar(max);
SET @sql = N'SELECT ' + CONVERT(varchar(12), @RowTo) + ' * 5';
EXEC sys.sp_executesql @sql;
In order to build that into a string (even if ultimately it will be a number), I need to convert it. But as you can see, the number is still treated as a number when it's executed. The answer is 25, right?
In your case you don't really need to re-declare @Rt etc. inside the @sql string, you just need to say:
SET @sql = @sql + ' WHERE RowNum BETWEEN '
+ CONVERT(varchar(12), @RowFrom) + ' AND '
+ CONVERT(varchar(12), @RowTo);
Though it would be better to have proper parameterization, e.g.
SET @sql = @sql + ' WHERE RowNum BETWEEN @RowFrom AND @RowTo;';
EXEC sys.sp_executesql @sql,
N'@RowFrom int, @RowTo int',
@RowFrom, @RowTo;
For the second part of your question, see the array page of the manual, which states (quoting) :
Array assignment always involves value copying. Use the reference operator to copy an array by reference.
And the given example :
<?php
$arr1 = array(2, 3);
$arr2 = $arr1;
$arr2[] = 4; // $arr2 is changed,
// $arr1 is still array(2, 3)
$arr3 = &$arr1;
$arr3[] = 4; // now $arr1 and $arr3 are the same
?>
For the first part, the best way to be sure is to try ;-)
Consider this example of code :
function my_func($a) {
$a[] = 30;
}
$arr = array(10, 20);
my_func($arr);
var_dump($arr);
It'll give this output :
array
0 => int 10
1 => int 20
Which indicates the function has not modified the "outside" array that was passed as a parameter : it's passed as a copy, and not a reference.
If you want it passed by reference, you'll have to modify the function, this way :
function my_func(& $a) {
$a[] = 30;
}
And the output will become :
array
0 => int 10
1 => int 20
2 => int 30
As, this time, the array has been passed "by reference".
Don't hesitate to read the References Explained section of the manual : it should answer some of your questions ;-)
Works for me:
select DATE( FROM_UNIXTIME( columnname ) ) from tablename;
I prefer to use ToString()
and IFormatProvider
.
double value = 100000.3
Console.WriteLine(value.ToString("0,0.00", new CultureInfo("en-US", false)));
Output: 10,000.30
because you used space between software engineer html/php will not support space between value under textbox, you have to use this code
<input type="text" name="txtJob" value=software_engineer>
It will work
The optimal solution for this is provide it as '0' and while using string use it as 'null' when using integer.
ex:
INSERT INTO table_name(column_name) VALUES(NULL);
It's similar to pass
in Python.
One use would be to stub out a function until it gets written:
future_function () { :; }
size_t
is an unsigned type that can hold maximum integer value for your architecture, so it is protected from integer overflows due to sign (signed int 0x7FFFFFFF
incremented by 1 will give you -1) or short size (unsigned short int 0xFFFF incremented by 1 will give you 0).
It is mainly used in array indexing/loops/address arithmetic and so on. Functions like memset()
and alike accept size_t
only, because theoretically you may have a block of memory of size 2^32-1
(on 32bit platform).
For such simple loops don't bother and use just int.
EditText txtUserID = (EditText) findViewById(R.id.txtUserID);
String UserID = txtUserID.getText().toString();
if (UserID.equals(""))
{
Log.d("value","null");
}
You will see the message in LogCat....
VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the results of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation.
On Error Resume Next
DoStep1
If Err.Number <> 0 Then
WScript.Echo "Error in DoStep1: " & Err.Description
Err.Clear
End If
DoStep2
If Err.Number <> 0 Then
WScript.Echo "Error in DoStop2:" & Err.Description
Err.Clear
End If
'If you no longer want to continue following an error after that block's completed,
'call this.
On Error Goto 0
The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above.

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }
and get these arguments inside update
method
update(e, space, txt){
console.log(e.target, space, txt);
}
event.target
gives you the native DOMNode
, then you need to use the regular DOM APIs to access attributes. For instance getAttribute
or dataset
<button
data-space="home"
className="home"
data-txt="Home"
onClick={ this.props.onClick }
/>
Button
</button>
onClick(e) {
console.log(e.target.dataset.txt, e.target.dataset.space);
}

You should be referencing a copy of the library that you copied to your development workspace—you should not reference the library directly from the Android SDK directory.
I faced this error because I referenced the original copy from SDK directory. Make sure that you first copy the library to android workspace and only reference it. In eclipse you can do it by checking "Copy projects into workspace" while importing the project.
I wrote this method to handle UTF8 arrays and JSON problems. It works fine with array (simple and multidimensional).
/**
* Encode array from latin1 to utf8 recursively
* @param $dat
* @return array|string
*/
public static function convert_from_latin1_to_utf8_recursively($dat)
{
if (is_string($dat)) {
return utf8_encode($dat);
} elseif (is_array($dat)) {
$ret = [];
foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);
return $ret;
} elseif (is_object($dat)) {
foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);
return $dat;
} else {
return $dat;
}
}
// Sample use
// Just pass your array or string and the UTF8 encode will be fixed
$data = convert_from_latin1_to_utf8_recursively($data);
Douglas Crockford has some very good explanations of inheritance in JavaScript:

for $d in $doc/element2/element3
return fn:string-join(fn:data($d/element()), ".")

$doc stores the Xml.
By setting and unsetting the setCustomValidity
in the right time, the validation message will work flawlessly.
<input name="Username" required
oninvalid="this.setCustomValidity('Username cannot be empty.')"
onchange="this.setCustomValidity('')" type="text" />
I used onchange
instead of oninput
which is more general and occurs when the value is changed in any condition even through JavaScript.
The main reason was the change from the proxy installed by the company recently, which has blocked other ssh connections other than those to the company domain.
I was able to connect successfully by following these steps:
ssh -T [email protected]
It should end up in a timeout.
ssh config --local -e
and from
[email protected]:asheeshjanghu/Journal.git
to
url=https://github.com/asheeshjanghu/Journal.git
The important point is that in the url you have to change at 2 places.
from git@
to https://
and from github:username
to github/username
In the end verify by doing a git fetch
It sounds trivial, but my issue was that I wasn't in the right project. Make sure you are in the project you expect to be in; otherwise, you won't be able to pull down the correct branches.
It's not a format suitable for blindly copying to another machine, but users who wish to work out whether they've added a repository yet or not (like I did), you can just do:
sudo apt update
When apt
is updating, it outputs a list of repositories it fetches. It seems obvious, but I've just realised what the GET
URLs are that it spits out.
The following awk
-based expression could be used to generate a sources.list file:
cat /tmp/apt-update.txt | awk '/http/ { gsub("/", " ", $3); gsub("^\s\*$", "main", $3); printf("deb "); if($4 ~ "^[a-z0-9]$") printf("[arch=" $4 "] "); print($2 " " $3) }' | sort | uniq
Alternatively, as other answers suggest, you could just cat
all the pre-existing sources like this:
cat /etc/apt/sources.list /etc/apt/sources.list.d/*
Since the disabled repositories are commented out with hash, this should work as intended.
It is written here that "By default, Android Studio 2.2 and the Android Plugin for Gradle 2.2 sign your app using both APK Signature Scheme v2 and the traditional signing scheme, which uses JAR signing."
As it seems that these new checkboxes appeared with Android 2.3, I understand that my previous versions of Android Studio (at least the 2.2) did sign with both signatures. So, to continue as I did before, I think that it is better to check both checkboxes.
EDIT March 31st, 2017 : submitted several apps with both signatures => no problem :)
If you are not required to use Apple's look and feel, a simple fix is to put the following code in your application or applet, before you add any GUI components to your JFrame or JApplet:
try {
UIManager.setLookAndFeel( UIManager.getCrossPlatformLookAndFeelClassName() );
} catch (Exception e) {
e.printStackTrace();
}
That will set the look and feel to the cross-platform look and feel, and the setBackground() method will then work to change a JButton's background color.

You can use slice method in javascript array object
<div ng-repeat="item in items.slice(0, 4)">{{item}}</div>
Short n sweet
From the PHP manual:
This is only called on reading/writing inaccessible properties. Your property however is public, which means it is accessible. Changing the access modifier to protected solves the issue.
You're looking for the setInterval
function, which runs a function every x milliseconds.
For example:
var start = new Date;
setInterval(function() {
$('.Timer').text((new Date - start) / 1000 + " Seconds");
}, 1000);
You can also use day names like Mon
for Monday, Tue
for Tuesday, etc. It's more human friendly.
The iScroll4 javascript library will fix it right up. It has a hideScrollbar
method that you can set to false
to prevent the scrollbar from disappearing.
It looks like get-pip.py
has been updated to use the environment variables http_proxy
and https_proxy
.
Windows:
set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py
Linux/OS X:
export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py
However if this still doesn't work for you, you can always install pip through a proxy using setuptools' easy_install
by setting the same environment variables.
Windows:
set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip
Linux/OS X:
export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip
Then once it's installed, use:
pip install --proxy="user:password@server:port" packagename
From the pip man page:
--proxy
Have pip use a proxy server to access sites. This can be specified using "user:[email protected]:port" notation. If the password is left out, pip will ask for it.

Here is how I create a tag:

Log.d(TAG, "some description");
You could use getCannonicalName

If you have any programming experience, you can probably learn the C# syntax in a few hours, and be comfortable with it within a week or so. However, you will not be writing complex structures unless you write a lot of code with it. It's really the same as learning any language: you can learn all the words and grammer fairly quickly, but it takes a while to be fluent.
EDIT
A book you may want to pick up for learning C# is C# in a Nutshell (3.0) which I found to be very useful, and has been recommended by several people here.
First of all, there're two kinds of keystores.
Individual and General
The application will use the one indicated in the startup or the default of the system.
It will be a different folder if JRE or JDK is running, or if you check the personal or the "global" one.
They are encrypted too
In short, the path will be like:
$JAVA_HOME/lib/security/cacerts
for the "general one", who has all the CA for the Authorities and is quite important.
Consider a solution that will neatly handle arbitrarily many tables.
//ASSUMPTION: All tables must have the same columns
var tables = new List<DataTable>();
tables.Add(oneTableToRuleThemAll);
tables.Add(oneTableToFindThem);
tables.Add(oneTableToBringThemAll);
tables.Add(andInTheDarknessBindThem);
//Or in the real world, you might be getting a collection of tables from some abstracted data source.
//behold, a table too great and terrible to imagine
var theOneTable = tables.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();
Encapsulated into a helper for future reuse:
public static DataTable CombineDataTables(params DataTable[] args)
{
return args.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();
}
Just have a few tables declared in code?
var combined = CombineDataTables(dt1,dt2,dt3);
Want to combine into one of the existing tables instead of creating a new one?
dt1 = CombineDataTables(dt1,dt2,dt3);
Already have a collection of tables, instead of declared one by one?
//Pretend variable tables already exists
var tables = new[] { dt1, dt2, dt3 };
var combined = CombineDataTables(tables);
During the install of python make sure you have "Install for all users" selected. Uninstall python and do a custom install and check "Install for all users".
header('Content-type: image/png')

Only difference is the capital 'T'.
Consider the Switch Function as an alternative to multiple IIf()
expressions. It will return the value from the first expression/value pair where the expression evaluates as True, and ignore any remaining pairs. The concept is similar to the SELECT ... CASE
approach you referenced but which is not available in Access SQL.
If you want to display a calculated field as commission
:
SELECT
Switch(
OpeningBalance < 5001, 20,
OpeningBalance < 10001, 30,
OpeningBalance < 20001, 40,
OpeningBalance >= 20001, 50
) AS commission
FROM YourTable;
If you want to store that calculated value to a field named commission
:
UPDATE YourTable
SET commission =
Switch(
OpeningBalance < 5001, 20,
OpeningBalance < 10001, 30,
OpeningBalance < 20001, 40,
OpeningBalance >= 20001, 50
);
Either way, see whether you find Switch()
easier to understand and manage. Multiple IIf()s
can become mind-boggling as the number of conditions grows.
You have two possibilities:
org.springframework.beans.factory.config.MethodInvokingFactoryBean
to invoke a static setter.In the first option you have a bean with a regular setter but instead setting an instance property you set the static property/field.
public void setTheProperty(Object value) {
foo.bar.Class.STATIC_VALUE = value;
}
but in order to do this you need to have an instance of a bean that will expose this setter (its more like an workaround).
In the second case it would be done as follows:
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> <property name="staticMethod" value="foo.bar.Class.setTheProperty"/> <property name="arguments"> <list> <ref bean="theProperty"/> </list> </property> </bean>
On you case you will add a new setter on the Utils
class:
public static setDataBaseAttr(Properties p)
and in your context you will configure it with the approach exemplified above, more or less like:
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> <property name="staticMethod" value="foo.bar.Utils.setDataBaseAttr"/> <property name="arguments"> <list> <ref bean="dataBaseAttr"/> </list> </property> </bean>
When a module is loaded from a file in Python, __file__
is set to its path. You can then use that with other functions to find the directory that the file is located in.
Taking your examples one at a time:
A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.
B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.
C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.
You can see the various values returned from these here:
import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))
and make sure you run it from different locations (such as ./text.py
, ~/python/text.py
and so forth) to see what difference that makes.
I just want to address some confusion first. __file__
is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.
http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.
In this case __file__
is an attribute of a module (a module object). In Python a .py
file is a module. So import amodule
will have an attribute of __file__
which means different things under difference circumstances.
Taken from the docs:
__file__
is the pathname of the file from which the module was loaded, if it was loaded from a file. The__file__
attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.
In your case the module is accessing it's own __file__
attribute in the global namespace.
To see this in action try:
# file: test.py
print globals()
print __file__
And run:
python test.py
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py
Batch files are not an executable. They need an application to run them (i.e. cmd).
On UNIX, the script file has shebang (#!) at the start of a file to specify the program that executes it. Double-clicking in Windows is performed by Windows Explorer. CreateProcess
does not know anything about that.
Runtime.
getRuntime().
exec("cmd /c start \"\" build.bat");
Note: With the start \"\"
command, a separate command window will be opened with a blank title and any output from the batch file will be displayed there. It should also work with just `cmd /c build.bat", in which case the output can be read from the sub-process in Java if desired.
i encountered this error in quite a stupid way
@Autowired
// private Bean bean;
public void myMethod() {
return;
}
what happened is that I commented a line for some reason and left the annotation which made spring think that the method needs to be autowired
row_count = sum(1 for line in open(filename))
worked for me.
Note : sum(1 for line in csv.reader(filename))
seems to calculate the length of first line
I have the same problem that I found some color in form of #AAAAAA
and I want to conver that into a form that android could make use of.
I found that you can just use 0xFFAAAAAA
so that android could automatically tell the color. Notice the first FF
is telling alpha
value.
Hope it helps
Instead of using
if(data !== null && data !== '' && data!==undefined) {
// do something
}
You can use below simple code
if(Boolean(value)){
// do something
}
Radio inputs must be inside of a form for 'checked' to work.

You should use back tick character (`) eg:
create table if not exists misc_info (
id INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
`key` TEXT UNIQUE NOT NULL,
value TEXT NOT NULL)ENGINE=INNODB;
Ping is meant to be sent only from server to client, and browser should answer as soon as possible with Pong OpCode, automatically. So you have not to worry about that on higher level.
Although that not all browsers support standard as they suppose to, they might have some differences in implementing such mechanism, and it might even means there is no Pong response functionality. But personally I am using Ping / Pong, and never saw client that does not implement this type of OpCode and automatic response on low level client side implementation.
If you're trying to find the first count
multiples of m
, something like this would work:
def multiples(m, count):
for i in range(count):
print(i*m)
Alternatively, you could do this with range:
def multiples(m, count):
for i in range(0,count*m,m):
print(i)
Note that both of these start the multiples at 0
- if you wanted to instead start at m
, you'd need to offset it by that much:
range(m,(count+1)*m,m)
Try setting a height on your td elements.
vertical-align: middle;
means the element the style is applied to will be aligned within the parent element. The height of the td may be only as high as the text inside.
Conditional statements are used to perform different actions based on different conditions.
Use if
to specify a block of code to be executed, if a specified condition is true
Use else
to specify a block of code to be executed, if the same condition is false
Use else if
to specify a new condition to test, if the first condition is false
The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization
header with the Bearer
authentication scheme.
This scheme is described by the RFC6750.
Example:
GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ
If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.
Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.
Unlike the custom JWT
scheme you mention in your question, the Bearer
one is registered at the IANA.
Concerning the Basic
and Digest
authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.
There's a --no-cache
option:
docker build --no-cache -t u12_core -f u12_core .
In older versions of Docker you needed to pass --no-cache=true
, but this is no longer the case.
C# added a new feature in Visual Studio 2010 called generate from usage. The intent is to generate the standard code from a usage pattern. One of the features is generating a constructor based off an initialization pattern.
The feature is accessible via the smart tag that will appear when the pattern is detected.
For example, let’s say I have the following class
class MyType {
}
And I write the following in my application
var v1 = new MyType(42);
A constructor taking an int
does not exist so a smart tag will show up and one of the options will be "Generate constructor stub". Selecting that will modify the code for MyType
to be the following.
class MyType {
private int p;
public MyType(int p) {
// TODO: Complete member initialization
this.p = p;
}
}
You can do it using jQuery. Example:
<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>
<script>
$.ajax({
url : "next.php",
type: "POST",
data : "name=Denniss",
success: function(data)
{
//data - response from server
$('#response_div').html(data);
}
});
</script>
Along the same lines as some of the suggestions you would need to do at least the following:
An example CSS could be as simple as this:
@media print {
body * {
display:none;
}
body .printable {
display:block;
}
}
Your JavaScript would then only need to apply the "printable" class to your target div and it will be the only thing visible (as long as there are no other conflicting CSS rules -- a separate exercise) when printing happens.
<script type="text/javascript">
function divPrint() {
// Some logic determines which div should be printed...
// This example uses div3.
$("#div3").addClass("printable");
window.print();
}
</script>
You may want to optionally remove the class from the target after printing has occurred, and / or remove the dynamically-added CSS after printing has occurred.
Below is a full working example, the only difference is that the print CSS is not loaded dynamically. If you want it to really be unobtrusive then you will need to load the CSS dynamically like in this answer.

def setUp(self, ):
desired = DesiredCapabilities.CHROME
desired ['loggingPrefs'] = { 'browser':'ALL' }
self.driver = webdriver.Chrome(desired_capabilities=desired)
def analyzeLog(self, ):
data = self.driver.get_log('browser')
print(data)
def testMethod(self, ):
self.setUp()
self.driver.get("http://mypage.com")

For everyone using editors like Komodo Edit (win10) add sys.stdout.flush()
to:
def mp_worker((inputs, the_time)):
print " Process %s\tWaiting %s seconds" % (inputs, the_time)
time.sleep(int(the_time))
print " Process %s\tDONE" % inputs
sys.stdout.flush()
or as first line to:
if __name__ == '__main__':
sys.stdout.flush()
This helps to see what goes on during the run of the script; in stead of having to look at the black command line box.
If using a StackTraceElement, use:
String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);
System.out.println(simpleClassName);

NOTE: This is true for the version mentioned in the question, 4.1.1.RELEASE.
Spring MVC handles a ResponseEntity
return value through HttpEntityMethodProcessor
.
When the ResponseEntity
value doesn't have a body set, as is the case in your snippet, HttpEntityMethodProcessor
tries to determine a content type for the response body from the parameterization of the ResponseEntity
return type in the signature of the @RequestMapping
handler method.
So for
public ResponseEntity<Void> taxonomyPackageExists( @PathVariable final String key ) {
that type will be Void
. HttpEntityMethodProcessor
will then loop through all its registered HttpMessageConverter
instances and find one that can write a body for a Void
type. Depending on your configuration, it may or may not find any.
If it does find any, it still needs to make sure that the corresponding body will be written with a Content-Type that matches the type(s) provided in the request's Accept
header, application/xml
in your case.
If after all these checks, no such HttpMessageConverter
exists, Spring MVC will decide that it cannot produce an acceptable response and therefore return a 406 Not Acceptable HTTP response.
With ResponseEntity<String>
, Spring will use String
as the response body and find StringHttpMessageConverter
as a handler. And since StringHttpMessageHandler
can produce content for any media type (provided in the Accept
header), it will be able to handle the application/xml
that your client is requesting.
Spring MVC has since been changed to only return 406 if the body in the ResponseEntity
is NOT null
. You won't see the behavior in the original question if you're using a more recent version of Spring MVC.
In iddy85's solution, which seems to suggest ResponseEntity<?>
, the type for the body will be inferred as Object
. If you have the correct libraries in your classpath, ie. Jackson (version > 2.5.0) and its XML extension, Spring MVC will have access to MappingJackson2XmlHttpMessageConverter
which it can use to produce application/xml
for the type Object
. Their solution only works under these conditions. Otherwise, it will fail for the same reason I've described above.
Being late to this, but after Java 8, I personally find this following approach with the Stream
API more concise and can be an alternative to the accepted answer.
For example,
Arrays.stream(new int[size]).boxed().collect(Collectors.toList())
where size
is the desired List
size and without the disadvantage mentioned here, all elements in the List
are initialized as 0
.
(I did a quick search and did not see stream
in any answers posted - feel free to let me know if this answer is redundant and I can remove it)
As a function:
def multi_delete(list_, *args):
indexes = sorted(list(args), reverse=True)
for index in indexes:
del list_[index]
return list_
Runs in n log(n) time, which should make it the fastest correct solution yet.
Use JavaScript function reset()
:
document.forms["frm_id"].reset();
I've always tested to find the MAX string length of an encrypted string and set that as the character length of a VARCHAR type. Depending on how many records you're going to have, it could really help the database size.
I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding
style="position: relative; bottom: 0px"
to your Widget2 tag. Also try:
style="position: absolute; bottom: 0px"
if you want to snap your widget to the bottom of the screen.
I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.
For username is same with some modification:
$user=$this->__('Welcome, %s!', Mage::getSingleton('customer/session')->getCustomer()->getName());
echo $user;
You should use PDO Prepare
From the link:
Calling PDO::prepare() and PDOStatement::execute() for statements that will be issued multiple times with different parameter values optimizes the performance of your application by allowing the driver to negotiate client and/or server side caching of the query plan and meta information, and helps to prevent SQL injection attacks by eliminating the need to manually quote the parameters.
psql -h <host> -p <port> -U <user> -d <db>
and update /var/lib/pgsql/10/data/pg_hba.conf
to change the auth method to cert
. Check the following link for more information:
This seems to work fine:
<button onclick="location.href='mailto:[email protected]';">send mail</button>
@Html.DropDownListFor(m => m.Departments.id, (SelectList)ViewBag.Department, "Select", htmlAttributes: new { @class = "form-control" })
If you want to use this in VBA:
For i = 1 To X
UserForm1.Controls("Label" & i).Caption = MySheet.Cells(i + 1, i).Value
Next
Outer Div must set its position
to relative
or fixed
, and the Inner Div must set its position
to absolute
, top
and left
to 50%
and apply a transform: translate(-50%, -50%)
.
div.cn {_x000D_
position: relative;_x000D_
width: 200px;_x000D_
height: 200px;_x000D_
background: gray;_x000D_
text-align: center;_x000D_
}_x000D_
_x000D_
div.inner {_x000D_
position: absolute;_x000D_
top: 50%;_x000D_
left: 50%;_x000D_
width: 100px;_x000D_
height: 100px;_x000D_
-webkit-transform: translate(-50%, -50%); _x000D_
transform: translate(-50%, -50%); _x000D_
background: red;_x000D_
_x000D_
}
_x000D_
<div class="cn">_x000D_
<div class="inner">_x000D_
test_x000D_
</div>_x000D_
</div>
_x000D_
Tested in:
Using a template trigger:
<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Background" Value="White"></Setter>
...
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="White"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I used this before..
public static Bitmap myblur(Bitmap image, Context context) {
final float BITMAP_SCALE = 0.4f;
final float BLUR_RADIUS = 7.5f;
int width = Math.round(image.getWidth() * BITMAP_SCALE);
int height = Math.round(image.getHeight() * BITMAP_SCALE);
Bitmap inputBitmap = Bitmap.createScaledBitmap(image, width, height, false);
Bitmap outputBitmap = Bitmap.createBitmap(inputBitmap);
RenderScript rs = RenderScript.create(context);
ScriptIntrinsicBlur theIntrinsic = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
Allocation tmpOut = Allocation.createFromBitmap(rs, outputBitmap);
theIntrinsic.setRadius(BLUR_RADIUS);
theIntrinsic.setInput(tmpIn);
theIntrinsic.forEach(tmpOut);
tmpOut.copyTo(outputBitmap);
return outputBitmap;
}
