I believe that phrase should have been worded as follows:
bcrypt has salts built into the generated hashes to prevent rainbow table attacks.
The bcrypt
utility itself does not appear to maintain a list of salts. Rather, salts are generated randomly and appended to the output of the function so that they are remembered later on (according to the Java implementation of bcrypt
). Put another way, the "hash" generated by bcrypt
is not just the hash. Rather, it is the hash and the salt concatenated.
The idea is that when you are designing a library only the classes that are intended for use from outside (by clients of your library) should be public. This way you can hide classes that
etc.
If you are developing inhouse solutions than using internal elements is not that important I guess, because usually the clients will have constant contact with you and/or access to the code. They are fairly critical for library developers though.
Adding the actual code here for future reference
So, there are 3 steps, and therefore 3 SQL statements:
Step 1: Move the non duplicates (unique tuples) into a temporary table
CREATE TABLE new_table as
SELECT * FROM old_table WHERE 1 GROUP BY [column to remove duplicates by];
Step 2: delete the old table (or rename it) We no longer need the table with all the duplicate entries, so drop it!
DROP TABLE old_table;
Step 3: rename the new_table to the name of the old_table
RENAME TABLE new_table TO old_table;
And of course, don't forget to fix your buggy code to stop inserting duplicates!
If you're wanting this as a script, the following Bash script should do what you want (plus tell you when the file already exists):
#!/bin/bash
if [ -e $1 ]; then
echo "File $1 already exists!"
else
echo >> $1
fi
If you don't want the "already exists" message, you can use:
#!/bin/bash
if [ ! -e $1 ]; then
echo >> $1
fi
Edit about using:
Save whichever version with a name you like, let's say "create_file" (quotes mine, you don't want them in the file name). Then, to make the file executatble, at a command prompt do:
chmod u+x create_file
Put the file in a directory in your path, then use it with:
create_file NAME_OF_NEW_FILE
The $1 is a special shell variable which takes the first argument on the command line after the program name; i.e. $1 will pick up NAME_OF_NEW_FILE in the above usage example.
Single quote must be there, since date converted to character.
Select employee_id, count(*) From Employee Where to_char(employee_date_hired, 'DD-MON-YY') > '31-DEC-95';
Yes, you can definitely do this. Just use something like
.parent:hover .child {
/* ... */
}
According to this page it's supported by all major browsers.
You can also cross reference repos:
githubuser/repository#xxx
xxx being the issue number
function setWidth(width) {
var canvas = document.getElementById("myCanvas");
canvas.width = width;
}
header( 'Location: http://www.yoursite.com/new_page.html' );
in your process.php file
I know, it's a tad bit too late to answer, but all you need to do is, force all forms dirty. Take a look at the following snippet:
angular.forEach($scope.myForm.$error.required, function(field) {
field.$setDirty();
});
and then you can check if your form is valid using:
if($scope.myForm.$valid) {
//Do something
}
and finally, I guess, you would want to change your route if everything looks good:
$location.path('/somePath');
Edit: form won't register itself on the scope until submit event is trigger. Just use ng-submit directive to call a function, and wrap the above in that function, and it should work.
For What its worth, this is what I did and maybe it can help others even though the article is old.
PHP:
session_start();
$_SESSION['ipaddress'] = $_SERVER['REMOTE_ADDR'];
if(isset($_SESSION['userID'])){
if(!strpos($_SESSION['activeID'], '-')){
$_SESSION['activeID'] = $_SESSION['userID'].'-'.$_SESSION['activeID'];
}
}elseif(!isset($_SESSION['activeID'])){
$_SESSION['activeID'] = time();
}
JS
window.setInterval(function(){
var userid = '<?php echo $_SESSION['activeID']; ?>';
var ipaddress = '<?php echo $_SESSION['ipaddress']; ?>';
var action = 'data';
$.ajax({
url:'activeUser.php',
method:'POST',
data:{action:action,userid:userid,ipaddress:ipaddress},
success:function(response){
//alert(response);
}
});
}, 5000);
Ajax call to activeUser.php
if(isset($_POST['action'])){
if(isset($_POST['userid'])){
$stamp = time();
$activeid = $_POST['userid'];
$ip = $_POST['ipaddress'];
$query = "SELECT stamp FROM activeusers WHERE activeid = '".$activeid."' LIMIT 1";
$results = RUNSIMPLEDB($query);
if($results->num_rows > 0){
$query = "UPDATE activeusers SET stamp = '$stamp' WHERE activeid = '".$activeid."' AND ip = '$ip' LIMIT 1";
RUNSIMPLEDB($query);
}else{
$query = "INSERT INTO activeusers (activeid,stamp,ip)
VALUES ('".$activeid."','$stamp','$ip')";
RUNSIMPLEDB($query);
}
}
}
Database:
CREATE TABLE `activeusers` (
`id` int(11) NOT NULL,
`activeid` varchar(20) NOT NULL,
`stamp` int(11) NOT NULL,
`ip` text
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
Basically every 5 seconds the js will post to a php file that will track the user and the users ip address. Active users are simply a database record that have an update to the database time stamp within 5 seconds. Old users stop updating to the database. The ip address is used just to ensure that a user is unique so 2 people on the site at the same time don't register as 1 user.
Probably not the most efficient solution but it does the job.
If I'm correct in thinking that you want to find the minimum value of a function for all possible pairs of 2 elements from a list...
l = [1,2,3,4,5]
def f(i,j):
return i+j
# Prints min value of f(i,j) along with i and j
print min( (f(i,j),i,j) for i in l for j in l)
A minor additional points worth mentioning. If you have a very large file you can on the fly calculate the number of rows (if no header) using (where bedGraph
is the name of your file in your working directory):
>numRow=as.integer(system(paste("wc -l", bedGraph, "| sed 's/[^0-9.]*\\([0-9.]*\\).*/\\1/'"), intern=T))
You can then use that either in read.csv
, read.table
...
>system.time((BG=read.table(bedGraph, nrows=numRow, col.names=c('chr', 'start', 'end', 'score'),colClasses=c('character', rep('integer',3)))))
user system elapsed
25.877 0.887 26.752
>object.size(BG)
203949432 bytes
As an alternative to $dollarsign
notation, use a within
block:
breast <- within(breast, {
class <- as.numeric(as.character(class))
})
Note that you want to convert your vector to a character before converting it to a numeric. Simply calling as.numeric(class)
will not the ids corresponding to each factor level (1, 2) rather than the levels themselves.

Updated answer (9/2/2019):
Homebrew has removed mongodb formula from its core repository, see this pull request.
The new way to install mongodb using Homebrew is as follows:
~> brew tap mongodb/brew
~> brew install mongodb-community
After installation you can start the mongodb service by following the caveats:
~> brew info mongodb-community
mongodb/brew/mongodb-community: stable 4.2.0
High-performance, schema-free, document-oriented database
https://www.mongodb.com/
Not installed
From: https://github.com/mongodb/homebrew-brew/blob/master/Formula/mongodb-community.rb
==> Caveats
To have launchd start mongodb/brew/mongodb-community now and restart at login:
brew services start mongodb/brew/mongodb-community
Or, if you don't want/need a background service you can just run:
mongod --config /usr/local/etc/mongod.conf
Deprecated answer (8/27/2019):
I assume you are using Homebrew. You can see the additional information that you need using brew info $FORMULA
~> brew info mongo 255
mongodb: stable 2.4.6, devel 2.5.1
http://www.mongodb.org/
/usr/local/Cellar/mongodb/2.4.5-x86_64 (20 files, 287M) *
Built from source
From: https://github.com/mxcl/homebrew/commits/master/Library/Formula/mongodb.rb
==> Caveats
To reload mongodb after an upgrade:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Caveats is what you need to follow after installation.
Bitmap
The accepted answer will crash when the Bitmap
is too large. I believe it's a 1MB limit. The Bitmap
must be compressed into a different file format such as a JPG represented by a ByteArray
, then it can be safely passed via an Intent
.
The function is contained in a separate thread using Kotlin Coroutines because the Bitmap
compression is chained after the Bitmap
is created from an url String
. The Bitmap
creation requires a separate thread in order to avoid Application Not Responding (ANR) errors.
toBitmap()
is a Kotlin extension function requiring that library to be added to the app dependencies.Bitmap
to JPG ByteArray
after it has been created.Repository.kt
suspend fun bitmapToByteArray(url: String) = withContext(Dispatchers.IO) {
MutableLiveData<Lce<ContentResult.ContentBitmap>>().apply {
postValue(Lce.Loading())
postValue(Lce.Content(ContentResult.ContentBitmap(
ByteArrayOutputStream().apply {
try {
BitmapFactory.decodeStream(URL(url).openConnection().apply {
doInput = true
connect()
}.getInputStream())
} catch (e: IOException) {
postValue(Lce.Error(ContentResult.ContentBitmap(ByteArray(0), "bitmapToByteArray error or null - ${e.localizedMessage}")))
null
}?.compress(CompressFormat.JPEG, BITMAP_COMPRESSION_QUALITY, this)
}.toByteArray(), "")))
}
}
ViewModel.kt
//Calls bitmapToByteArray from the Repository
private fun bitmapToByteArray(url: String) = liveData {
emitSource(switchMap(repository.bitmapToByteArray(url)) { lce ->
when (lce) {
is Lce.Loading -> liveData {}
is Lce.Content -> liveData {
emit(Event(ContentResult.ContentBitmap(lce.packet.image, lce.packet.errorMessage)))
}
is Lce.Error -> liveData {
Crashlytics.log(Log.WARN, LOG_TAG,
"bitmapToByteArray error or null - ${lce.packet.errorMessage}")
}
}
})
}
ByteArray
via an Intent
.In this sample it's passed from a Fragment to a Service. It's the same concept if being shared between two Activities.
Fragment.kt
ContextCompat.startForegroundService(
context!!,
Intent(context, AudioService::class.java).apply {
action = CONTENT_SELECTED_ACTION
putExtra(CONTENT_SELECTED_BITMAP_KEY, contentPlayer.image)
})
ByteArray
back to Bitmap
.Utils.kt
fun ByteArray.byteArrayToBitmap(context: Context) =
run {
BitmapFactory.decodeByteArray(this, BITMAP_OFFSET, size).run {
if (this != null) this
// In case the Bitmap loaded was empty or there is an error I have a default Bitmap to return.
else AppCompatResources.getDrawable(context, ic_coinverse_48dp)?.toBitmap()
}
}
If you want an alert that is fixed to the top and you are using bootstrap navbar navbar-fixed-top the following style class will overlay they alert on top of the nav:
.alert-fixed {
position:fixed;
top: 0px;
left: 0px;
width: 100%;
z-index:9999;
border-radius:0px
}
This worked well for me to provide alerts even when the user is scrolled down in the page.
If $arrayofStringsNotInterestedIn is an [array] you should use -notcontains:
Get-Content $FileName | foreach-object { `
if ($arrayofStringsNotInterestedIn -notcontains $_) { $) }
or better (IMO)
Get-Content $FileName | where { $arrayofStringsNotInterestedIn -notcontains $_}
Got the fix in css.
td.disabledAnchor a{
pointer-events: none !important;
cursor: default;
color:Gray;
}
Above css when applied to the anchor tag will disable the click event.
For details checkout this link
This will update all the rows in that columns if safe mode is not enabled.
UPDATE table SET columnB = columnA;
If safe mode is enabled then you will need to use a where clause. I use primary key as greater than 0 basically all will be updated
UPDATE table SET columnB = columnA where table.column>0;
git push
can push all branches or a single one dependent on this configuration:
Push all branches
git config --global push.default matching
It will push all the branches to the remote branch and would merge them.
If you don't want to push all branches, you can push the current branch if you fully specify its name, but this is much is not different from default
.
Push only the current branch if its named upstream is identical
git config --global push.default simple
So, it's better, in my opinion, to use this option and push your code branch by branch. It's better to push branches manually and individually.
I found that when mixed with PCL libraries the above problem presented itself, and whilst it is true that the WindowsBase library contains System.IO.Packaging I was using the OpenXMLSDK-MOT 2.6.0.0 library which itself provides it's own copy of the physical System.IO.Packaging library. The reference that was missing for me could be found as follows in the csharp project
<Reference Include="System.IO.Packaging, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
<HintPath>..\..\..\..\packages\OpenXMLSDK-MOT.2.6.0.0\lib\System.IO.Packaging.dll</HintPath>
<Private>True</Private>
</Reference>
I downgraded my version of the XMLSDK to 2.6 which then seemed to fix this problem up for me. But you can see there is a physical assembly System.IO.Packaging.dll
Seems like you are using an image from a URL that has not set correct Access-Control-Allow-Origin header and hence the issue.. You can fetch that image from your server and get it from your server to avoid CORS issues..
I found that setting the time out settings in HttpConnectionParams
and HttpConnectionManager
did not solve our case. We're limited to using org.apache.commons.httpclient

This is probably the closest translation from your C code to Python code.
A = 1
B = "hello"
buf = "A = %d\n , B= %s\n" % (A, B)
c = 2
buf += "C=%d\n" % c
f = open('output.txt', 'w')
print >> f, c
f.close()
The %
operator in Python does almost exactly the same thing as C's sprintf
. You can also print the string to a file directly. If there are lots of these string formatted stringlets involved, it might be wise to use a StringIO
object to speed up processing time.
So instead of doing +=
, do this:
import cStringIO
buf = cStringIO.StringIO()
...
print >> buf, "A = %d\n , B= %s\n" % (A, B)
...
print >> buf, "C=%d\n" % c
...
print >> f, buf.getvalue()

Exim 4 requires that AUTH command only be sent after the client issued EHLO - attempts to authenticate without EHLO would be rejected. Some mailservers require that EHLO be issued twice. PHPMailer apparently fails to do so. If PHPMailer does not allow you to force EHLO initiation, you really should switch to SwiftMailer 4.
This seems a little bit like homework. So I'll give you some hints. The good news is that you're almost there! You've done most of the hard work already!

If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.
To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.
Then click 'Microsoft WCF Web Service Reference':
Enter the file path into URI text box and import the WSDL:
It will generate a simple, very basic WCF client and you to use it something like this:
YourServiceClient client = new YourServiceClient();
client.DoSomething();

You should think carefully about changes over time, versioning, stability, compatibility, etc.
If there are two apps that use the shared code, do you want to force those apps to change together, in case they need to be compatible with each other? Then use the dll. All the exe's will be using the same code.
Or do you want to isolate them from each other, so that you can change one and be confident you haven't broken the other. Then use the static lib.
DLL hell is when you probably SHOULD HAVE used a static lib, but you used a dll instead, and not all the exes are comaptible with it.
Please not that rand()
does not generate a cryptographically secure value according to the docs:
http://php.net/manual/en/function.rand.php
This function does not generate cryptographically secure values, and should not be used for cryptographic purposes. If you need a cryptographically secure value, consider using random_int(), random_bytes(), or openssl_random_pseudo_bytes() instead.
Instead it is better to use random_int()
, available on PHP 7 (See: http://php.net/manual/en/function.random-int.php).
So to extend @Marcus's answer, you should use:
function generateSecureRandomNumber($digits): int {
return random_int(pow(10, $digits - 1), pow(10, $digits) - 1);
}
function generateSecureRandomNumberWithPadding($digits): string {
$randomNumber = random_int(0, pow(10, $digits) - 1);
return str_pad($randomNumber, $digits, '0', STR_PAD_LEFT);
}
Note that using rand()
is fine if you don't need a secure random number.
@Autowired + @Qualifier will work only with spring DI, if you want to use some other DI in future @Resource is good option.
other difference which I found very significant is @Qualifier does not support dynamic bean wiring, as @Qualifier does not support placeholder, while @Resource does it very well.
For example: if you have an interface with multiple implementations like this
interface parent {
}
@Service("actualService")
class ActualService implements parent{
}
@Service("stubbedService")
class SubbedService implements parent{
}
with @Autowired & @Qualifier you need to set specific child implementation like
@Autowired
@Qualifier("actualService") or
@Qualifier("stubbedService")
Parent object;
which does not provide placeholder while with @Resource you can put placeholder and use property file to inject specific child implementation like
@Resource(name="${service.name}")
Parent object;
where service.name is set in property file as
#service.name=actualService
service.name=stubbedService
Hope that helps someone :)
... is syntax for variadic arguments.
I think it is implemented by the complier using slice ([]Type)
, just like the function append :
func append(slice []Type, elems ...Type) []Type
when you use "elems" in "append", actually it is a slice([]type).
So "a = append(a[:0], a[1:]...)
" means "a = append(a[0:0], a[1:])
"
a[0:0]
is a slice which has nothing
a[1:]
is "Hello2 Hello3"
This is how it works
I think its already been answered before, but just a correction if you are populating an unordered list, the *ngFor
will come in the element which you want to repeat. So it should be insdide <li>
. Also, Angular2 now uses let to declare a variable.
<ul>
<li *ngFor="let item of items; let i = index" [attr.data-index]="i">
{{item}}
</li>
</ul>
If your server is still listening on port 80, check the permission on the DocumentRoot folder and if DirectoryIndex file existed.
I know that this question is old but I think my answer would help those who haven't found solution in other answers. So, my problem was that I couldn't display croatian characters in my PDF. Firstly, I used FPDF but, I think, it does not support Unicode. Finally, what solved my problem is tFPDF which is the version of FPDF that supports Unicode. This is the example that worked for me:
require('tFPDF/tfpdf.php');
$pdf = new tFPDF();
$pdf->AddPage();
$pdf->AddFont('DejaVu','','DejaVuSansCondensed.ttf',true);
$pdf->AddFont('DejaVu', 'B', 'DejaVuSansCondensed-Bold.ttf', true);
$pdf->SetFont('DejaVu','',14);
$txt = 'ccžšdCCŽŠÐ';
$pdf->Write(8,$txt);
$pdf->Output();
No.
An ArrayList can be empty (or with nulls as items) an not be null. It would be considered empty. You can check for am empty ArrayList with:
ArrayList arrList = new ArrayList();
if(arrList.isEmpty())
{
// Do something with the empty list here.
}
Or if you want to create a method that checks for an ArrayList with only nulls:
public static Boolean ContainsAllNulls(ArrayList arrList)
{
if(arrList != null)
{
for(object a : arrList)
if(a != null) return false;
}
return true;
}
find $HOME -name "hello.c" -print
This will search the whole $HOME
(i.e. /home/username/
) system for any files named “hello.c” and display their pathnames:
/Users/user/Downloads/hello.c
/Users/user/hello.c
However, it will not match HELLO.C
or HellO.C
. To match is case insensitive pass the -iname
option as follows:
find $HOME -iname "hello.c" -print
Sample outputs:
/Users/user/Downloads/hello.c
/Users/user/Downloads/Y/Hello.C
/Users/user/Downloads/Z/HELLO.c
/Users/user/hello.c
Pass the -type f
option to only search for files:
find /dir/to/search -type f -iname "fooBar.conf.sample" -print
find $HOME -type f -iname "fooBar.conf.sample" -print
The -iname
works either on GNU or BSD (including OS X) version find command. If your version of find command does not supports -iname
, try the following syntax using grep
command:
find $HOME | grep -i "hello.c"
find $HOME -name "*" -print | grep -i "hello.c"
OR try
find $HOME -name '[hH][eE][lL][lL][oO].[cC]' -print
Sample outputs:
/Users/user/Downloads/Z/HELLO.C
/Users/user/Downloads/Z/HEllO.c
/Users/user/Downloads/hello.c
/Users/user/hello.c
You can build it with list comprehension like this:
>>> dict((i, range(int(i), int(i) + 2)) for i in ['1', '2'])
{'1': [1, 2], '2': [2, 3]}
And for the second part of your question use defaultdict
>>> from collections import defaultdict
>>> s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
>>> d = defaultdict(list)
>>> for k, v in s:
d[k].append(v)
>>> d.items()
[('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])]
Actually, char* name
is not a pointer to a constant, but a pointer to a variable. You might be talking about this other question.
What is the difference between char * const and const char *?
It's called the protocol. The only thing that prevents you from making your own protocol is you have to:
Windows makes #1 really easy, an in many cases this is all you actually need. Viz:
Pure bash
, no basename
, no variable juggling. Set a string and echo
:
p=/the/path/foo.txt
echo "${p//+(*\/|.*)}"
Output:
foo
Note: the bash
extglob option must be "on", (Ubuntu sets extglob "on" by default), if it's not, do:
shopt -s extglob
Walking through the ${p//+(*\/|.*)}
:
${p

end parameter expansion. With a string substitution, there's usually another /
there, followed by a replacement string. But since there's no /
there, the matched patterns are substituted with nothing; this deletes the matches.Relevant man bash
background:
${parameter/pattern/string} Pattern substitution. The pattern is expanded to produce a pat tern just as in pathname expansion. Parameter is expanded and the longest match of pattern against its value is replaced with string. If pattern begins with /, all matches of pattern are replaced with string. Normally only the first match is replaced. If pattern begins with #, it must match at the begin- ning of the expanded value of parameter. If pattern begins with %, it must match at the end of the expanded value of parameter. If string is null, matches of pattern are deleted and the / fol lowing pattern may be omitted. If parameter is @ or *, the sub stitution operation is applied to each positional parameter in turn, and the expansion is the resultant list. If parameter is an array variable subscripted with @ or *, the substitution operation is applied to each member of the array in turn, and the expansion is the resultant list.
If the extglob shell option is enabled using the shopt builtin, several extended pattern matching operators are recognized. In the following description, a pattern-list is a list of one or more patterns separated by a |. Composite patterns may be formed using one or more of the fol lowing sub-patterns: ?(pattern-list) Matches zero or one occurrence of the given patterns *(pattern-list) Matches zero or more occurrences of the given patterns +(pattern-list) Matches one or more occurrences of the given patterns @(pattern-list) Matches one of the given patterns !(pattern-list) Matches anything except one of the given patterns
Run this command:-
rails g migration drop_table_name
then:
rake db:migrate
or if you are using MySql database then:
show databases;
show tables;
drop table_name;
This has bitten me a second time so I thought might be worth mentioning. The line listen_addresses = '*' in the postgresql.conf is by default commented. Be sure to uncomment (remove the pound sign, # at the beginning) it after updating otherwise, remote connections will continue to be blocked.
You can execute commands in parallel with start
like this:
start "" ping myserver
start "" nslookup myserver
start "" morecommands
They will each start in their own command prompt and allow you to run multiple commands at the same time from one batch file.
Hope this helps!
The syntax is as follows:
new Date(year, month [, day, hour, minute, second, millisecond ])
so
Date d = new Date(2011,10,30);
is correct; day, hour, minute, second, millisecond are optional.

You can center auto width div using display:table;
div{
margin: 0px auto;
float: none;
display: table;
}
Try this:
<?php
$str = "This is some <b>bold</b> text.";
echo htmlspecialchars($str);
?>
In Python 2.*
, input
lets the user enter any expression, e.g. a tuple:
>>> a, b = input('Two numbers please (with a comma in between): ')
Two numbers please (with a comma in between): 23, 45
>>> print a, b
23 45
In Python 3.*
, input
is like 2.*
's raw_input
, returning you a string that's just what the user typed (rather than eval
ing it as 2.*
used to do on input
), so you'll have to .split
, and/or eval
, &c but you'll also be MUCH more in control of the whole thing.
For :
abc:number|string;
Use the JavaScript operator typeof
:
if (typeof abc === "number") {
// do something
}
TypeScript understands typeof
This is called a typeguard.
For classes you would use instanceof
e.g.
class Foo {}
class Bar {}
// Later
if (fooOrBar instanceof Foo){
// TypeScript now knows that `fooOrBar` is `Foo`
}
There are also other type guards e.g. in
etc https://basarat.gitbooks.io/typescript/content/docs/types/typeGuard.html
If you want to use less code, you can also use the norm
in the stats
package (the 'F' stands for Forbenius, which is the Euclidean norm):
norm(matrix(x1-x2), 'F')
While this may look a bit neater, it's not faster. Indeed, a quick test on very large vectors shows little difference, though so12311's method is slightly faster. We first define:
set.seed(1234)
x1 <- rnorm(300000000)
x2 <- rnorm(300000000)
Then testing for time yields the following:
> system.time(a<-sqrt(sum((x1-x2)^2)))
user system elapsed
1.02 0.12 1.18
> system.time(b<-norm(matrix(x1-x2), 'F'))
user system elapsed
0.97 0.33 1.31
One way is to use the version of parse that takes an InputSource rather than a file
A SAX InputSource can be constructed from a Reader object. One Reader object is the StringReader
So something like
parse(new InputSource(new StringReader(myString))) may work.
Read up on the configuration settings (e.g., display_errors
, display_startup_errors
, log_errors
) and update your php.ini
or .htaccess
or .user.ini
file, whichever is appropriate.
It works.
If you're constructing an array via mutability and then want to return an immutable version, you can simply return the mutable array as an "NSArray" via inheritance.
- (NSArray *)arrayOfStrings {
NSMutableArray *mutableArray = [NSMutableArray array];
mutableArray[0] = @"foo";
mutableArray[1] = @"bar";
return mutableArray;
}
If you "trust" the caller to treat the (technically still mutable) return object as an immutable NSArray, this is a cheaper option than [mutableArray copy]
.
To determine whether it can change a received object, the receiver of a message must rely on the formal type of the return value. If it receives, for example, an array object typed as immutable, it should not attempt to mutate it. It is not an acceptable programming practice to determine if an object is mutable based on its class membership.
The above practice is discussed in more detail here:
Best Practice: Return mutableArray.copy or mutableArray if return type is NSArray
On GNU versions of find you can use -executable
:
find . -type f -executable -print
For BSD versions of find, you can use -perm
with +
and an octal mask:
find . -type f -perm +111 -print
In this context "+" means "any of these bits are set" and 111 is the execute bits.
Note that this is not identical to the -executable
predicate in GNU find. In particular, -executable
tests that the file can be executed by the current user, while -perm +111
just tests if any execute permissions are set.
Older versions of GNU find also support the -perm +111
syntax, but as of 4.5.12 this syntax is no longer supported. Instead, you can use -perm /111
to get this behavior.
success
is the callback that is invoked when the request is successful and is part of the $.ajax
call. done
is actually part of the jqXHR
object returned by $.ajax()
, and replaces success
in jQuery 1.8.
One solution is to create a named class instead of using an anonymous class. Give that named class a constructor that takes whatever parameters you wish and assigns them to class fields:
class MenuActionListener implements ActionListener {
private Color kolorIkony;
public MenuActionListener(Color kolorIkony) {
this.kolorIkony = kolorIkony
}
@Override
public void actionPerformed(ActionEvent e) {
JMenuItem item = (JMenuItem) e.getSource();
IconA icon = (IconA) item.getIcon();
// Use the class field here
textArea.setForeground(kolorIkony);
}
});
Now you can create an instance of this class as usual:
Jmi.addActionListener(new MenuActionListener(getColor(colors[mi]));
I have met the similiar issue. I would link to run Ant task fron Maven build and I got the issue. I have fixed it as bellow steps:
And it worked for me.
I was running a job which ran a shell script in Jenkins on a Windows machine. The job was failing due to the error given below. I was able to fix the error thanks to clues in Andrejz's answer.

Solution :
1 - Install Cygwin and note the directory where it gets installed.
It was C:\cygwin64 in my case. The sh.exe which is needed to run shell scripts is in the "bin" sub-directory, i.e. C:\cygwin64\bin.
2 - Tell Jenkins where sh.exe is located.
Jenkins web console > Manage Jenkins > Configure System > Under shell, set the "Shell executable" = C:\cygwin64\bin\sh.exe > Click apply & also click save.
That's all I did to make my job pass. I was running Jenkins from a war file and I did not need to restart it to make this work.
You could also pass points to the function: Small example:
def test(points):
addpoint = raw_input ("type ""add"" to add a point")
if addpoint == "add":
points = points + 1
else:
print "asd"
return points;
if __name__ == '__main__':
points = 0
for i in range(10):
points = test(points)
print points
I had a similar problem. I was attempting to have a file written every time a user visits a website.
The problem ended up being twofold.
1: the permissions were not set correctly
2: I attempted to use
f = open(r"newfile.txt","w+")
(Wrong)
After changing the file to 777 (all users can read/write)
chmod 777 /var/www/path/to/file
and changing the path to an absolute path, my problem was solved
f = open(r"/var/www/path/to/file/newfile.txt","w+")
(Right)
I'd love to use regex to accomplish this, but since you can only use lists, loops, functions, etc..
here's what I came up with:
stringWithNumbers="I have 10 bananas for my 5 monkeys!"
stringWithoutNumbers=''.join(c if c not in map(str,range(0,10)) else "" for c in stringWithNumbers)
print(stringWithoutNumbers) #I have bananas for my monkeys!
If file filename.tar.gz
gives this message: POSIX tar archive,
the archive is a tar, not a GZip archive.
Unpack a tar without the z
, it is for gzipped (compressed), only:
mv filename.tar.gz filename.tar # optional
tar xvf filename.tar
Or try a generic Unpacker like unp
(https://packages.qa.debian.org/u/unp.html), a script for unpacking a wide variety of archive formats.
determine the file type:
$ file ~/Downloads/filename.tbz2
/User/Name/Downloads/filename.tbz2: bzip2 compressed data, block size = 400k
@Henrik's is better for usability as this will make the column character and no longer numeric but matches what you asked for...

Below is a list of the common key codes for quick reference, taken from Events.h
.
If you need to use these keycodes in an application, you should include the Carbon framework:
Objective-C:
#include <Carbon/Carbon.h>
Swift:
import Carbon.HIToolbox
You can then use the kVK_ANSI_A
constants directly.
The key constants reference physical keys on the keyboard. Their output changes if the typist is using a different keyboard layout. The letters in the constants correspond only to the U.S. QWERTY keyboard layout.
For example, the left ring-finger key on the homerow:
QWERTY keyboard layout
> s > kVK_ANSI_S
> "s"
Dvorak keyboard layout
> o > kVK_ANSI_S
> "o"
Strategies for layout-agnostic conversion of keycode to string, and vice versa, are discussed here:
How to convert ASCII character to CGKeyCode?
From Events.h
:
/*
* Summary:
* Virtual keycodes
*
* Discussion:
* These constants are the virtual keycodes defined originally in
* Inside Mac Volume V, pg. V-191. They identify physical keys on a
* keyboard. Those constants with "ANSI" in the name are labeled
* according to the key position on an ANSI-standard US keyboard.
* For example, kVK_ANSI_A indicates the virtual keycode for the key
* with the letter 'A' in the US keyboard layout. Other keyboard
* layouts may have the 'A' key label on a different physical key;
* in this case, pressing 'A' will generate a different virtual
* keycode.

The project JsonSubTypes implement a generic converter that handle this feature with the helps of attributes.
For the concrete sample provided here is how it works:

[JsonSubtypes.KnownSubTypeWithProperty(typeof(Artist), "Skill")]
public class Person
{
public string FirstName { get; set; }

}
public class Employee : Person
{
public string Department { get; set; }
public string JobTitle { get; set; }
}
public class Artist : Person
{
public string Skill { get; set; }
}

A callback function, also known as a higher-order function, is a function that is passed to another function as a parameter, and the callback function is called (or executed) inside the parent function.
$("#button_1").click(function() {
alert("button 1 Clicked");
});
Here we have pass a function as a parameter to the click method. And the click method will call (or execute) the callback function we passed to it.
I got same problem, I tried all above, noting solved my problem. Luckely, I solved the problem this way:
echo $SHELL
Output
/bin/zsh
OR
/bin/bash
If it showing "bash" in output. You have to add env properties in .bashrc file (.bash_profile i did not tried, you can try) or else
It is showing 'zsh' in output. You have to add env properties in .zshrc file, if not exist already you create one no issue.
This should work in modern browsers:
input[value]:not([value=""])
It selects all inputs with value attribute and then select inputs with non empty value among them.
Broadcast receivers receive events of a certain type. I don't think you can invoke them by class name.
First, your IntentFilter must contain an event.
static final String SOME_ACTION = "com.yourcompany.yourapp.SOME_ACTION";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);
Second, when you send a broadcast, use this same action:
Intent i = new Intent(SOME_ACTION);
sendBroadcast(i);
Third, do you really need MyIntentService to be inline? Static? [EDIT] I discovered that MyIntentSerivce MUST be static if it is inline.
Fourth, is your service declared in the AndroidManifest.xml?
Here's a more simple version of essentially the same file.
@echo off

Most of the answers here give useful suggestions for when you have a single async operation, but sometimes, this comes up when you need to do an asynchronous operation for each entry in an array or other list-like structure. The temptation is to do this:
// WRONG
var results = [];
theArray.forEach(function(entry) {
doSomethingAsync(entry, function(result) {
results.push(result);
});
});
console.log(results); // E.g., using them, returning them, etc.
Example:
// WRONG_x000D_
var theArray = [1, 2, 3];_x000D_
var results = [];_x000D_
theArray.forEach(function(entry) {_x000D_
doSomethingAsync(entry, function(result) {_x000D_
results.push(result);_x000D_
});_x000D_
});_x000D_
console.log("Results:", results); // E.g., using them, returning them, etc._x000D_
_x000D_
function doSomethingAsync(value, callback) {_x000D_
console.log("Starting async operation for " + value);_x000D_
setTimeout(function() {_x000D_
console.log("Completing async operation for " + value);_x000D_
callback(value * 2);_x000D_
}, Math.floor(Math.random() * 200));_x000D_
}
_x000D_
.as-console-wrapper {_x000D_
max-height: 100% !important;_x000D_
}
_x000D_
The reason that doesn't work is that the callbacks from doSomethingAsync
haven't run yet by the time you're trying to use the results.
So, if you have an array (or list of some kind) and want to do async operations for each entry, you have two options: Do the operations in parallel (overlapping), or in series (one after another in sequence).
You can start all of them and keep track of how many callbacks you're expecting, and then use the results when you've gotten that many callbacks:
var results = [];
var expecting = theArray.length;
theArray.forEach(function(entry, index) {
doSomethingAsync(entry, function(result) {
results[index] = result;
if (--expecting === 0) {
// Done!
console.log("Results:", results); // E.g., using the results
}
});
});
Example:
var theArray = [1, 2, 3];_x000D_
var results = [];_x000D_
var expecting = theArray.length;_x000D_
theArray.forEach(function(entry, index) {_x000D_
doSomethingAsync(entry, function(result) {_x000D_
results[index] = result;_x000D_

(We could do away with expecting
and just use results.length === theArray.length
, but that leaves us open to the possibility that theArray
is changed while the calls are outstanding...)
Notice how we use the index
from forEach
to save the result in results
in the same position as the entry it relates to, even if the results arrive out of order (since async calls don't necessarily complete in the order in which they were started).
But what if you need to return those results from a function? As the other answers have pointed out, you can't; you have to have your function accept and call a callback (or return a Promise). Here's a callback version:
function doSomethingWith(theArray, callback) {
var results = [];
var expecting = theArray.length;
theArray.forEach(function(entry, index) {
doSomethingAsync(entry, function(result) {
results[index] = result;
if (--expecting === 0) {
// Done!
callback(results);
}
});
});
}
doSomethingWith(theArray, function(results) {
console.log("Results:", results);
});
Example:
function doSomethingWith(theArray, callback) {_x000D_
var results = [];_x000D_
var expecting = theArray.length;_x000D_
theArray.forEach(function(entry, index) {_x000D_
doSomethingAsync(entry, function(result) {_x000D_
results[index] = result;_x000D_
if (--expecting === 0) {_x000D_
// Done!_x000D_
callback(results);_x000D_
}_x000D_
});_x000D_
});_x000D_
}_x000D_
doSomethingWith([1, 2, 3], function(results) {_x000D_
console.log("Results:", results);_x000D_
});_x000D_
_x000D_
function doSomethingAsync(value, callback) {_x000D_
console.log("Starting async operation for " + value);_x000D_
setTimeout(function() {_x000D_
console.log("Completing async operation for " + value);_x000D_
callback(value * 2);_x000D_
}, Math.floor(Math.random() * 200));_x000D_
}
_x000D_
.as-console-wrapper {_x000D_
max-height: 100% !important;_x000D_
}
_x000D_
Or here's a version returning a Promise
instead:
function doSomethingWith(theArray) {
return new Promise(function(resolve) {
var results = [];
var expecting = theArray.length;
theArray.forEach(function(entry, index) {
doSomethingAsync(entry, function(result) {
results[index] = result;
if (--expecting === 0) {
// Done!
resolve(results);
}
});
});
});
}
doSomethingWith(theArray).then(function(results) {
console.log("Results:", results);
});
Of course, if doSomethingAsync
passed us errors, we'd use reject
to reject the promise when we got an error.)
Example:
function doSomethingWith(theArray) {_x000D_
return new Promise(function(resolve) {_x000D_
var results = [];_x000D_
var expecting = theArray.length;_x000D_
theArray.forEach(function(entry, index) {_x000D_
doSomethingAsync(entry, function(result) {_x000D_
results[index] = result;_x000D_
if (--expecting === 0) {_x000D_
// Done!_x000D_
resolve(results);_x000D_
}_x000D_
});_x000D_
});_x000D_
});_x000D_
}_x000D_

console.log("Results:", results);_x000D_
});_x000D_
_x000D_
function doSomethingAsync(value, callback) {_x000D_
console.log("Starting async operation for " + value);_x000D_
setTimeout(function() {_x000D_
console.log("Completing async operation for " + value);_x000D_

(Or alternately, you could make a wrapper for doSomethingAsync
that returns a promise, and then do the below...)
If doSomethingAsync
gives you a Promise, you can use Promise.all
:
function doSomethingWith(theArray) {
return Promise.all(theArray.map(function(entry) {
return doSomethingAsync(entry);
}));
}
doSomethingWith(theArray).then(function(results) {
console.log("Results:", results);
});
If you know that doSomethingAsync
will ignore a second and third argument, you can just pass it directly to map
(map
calls its callback with three arguments, but most people only use the first most of the time):
function doSomethingWith(theArray) {
return Promise.all(theArray.map(doSomethingAsync));
}
doSomethingWith(theArray).then(function(results) {
console.log("Results:", results);
});
Example:
function doSomethingWith(theArray) {_x000D_
return Promise.all(theArray.map(doSomethingAsync));_x000D_
}_x000D_
doSomethingWith([1, 2, 3]).then(function(results) {_x000D_
console.log("Results:", results);_x000D_
});_x000D_
_x000D_
function doSomethingAsync(value) {_x000D_
console.log("Starting async operation for " + value);_x000D_
return new Promise(function(resolve) {_x000D_
setTimeout(function() {_x000D_
console.log("Completing async operation for " + value);_x000D_
resolve(value * 2);_x000D_
}, Math.floor(Math.random() * 200));_x000D_
});_x000D_
}
_x000D_
.as-console-wrapper {_x000D_
max-height: 100% !important;_x000D_
}
_x000D_
Note that Promise.all
resolves its promise with an array of the results of all of the promises you give it when they are all resolved, or rejects its promise when the first of the promises you give it rejects.
Suppose you don't want the operations to be in parallel? If you want to run them one after another, you need to wait for each operation to complete before you start the next. Here's an example of a function that does that and calls a callback with the result:
function doSomethingWith(theArray, callback) {
var results = [];
doOne(0);
function doOne(index) {
if (index < theArray.length) {
doSomethingAsync(theArray[index], function(result) {
results.push(result);
doOne(index + 1);
});
} else {
// Done!
callback(results);
}
}
}
doSomethingWith(theArray, function(results) {
console.log("Results:", results);
});
(Since we're doing the work in series, we can just use results.push(result)
since we know we won't get results out of order. In the above we could have used results[index] = result;
, but in some of the following examples we don't have an index to use.)
Example:
function doSomethingWith(theArray, callback) {_x000D_
var results = [];_x000D_
doOne(0);_x000D_
function doOne(index) {_x000D_
if (index < theArray.length) {_x000D_
doSomethingAsync(theArray[index], function(result) {_x000D_
results.push(result);_x000D_
doOne(index + 1);_x000D_
});_x000D_
} else {_x000D_
// Done!_x000D_
callback(results);_x000D_
}_x000D_
}_x000D_
}_x000D_

console.log("Results:", results);_x000D_
});_x000D_
_x000D_

callback(value * 2);_x000D_
}, Math.floor(Math.random() * 200));_x000D_

(Or, again, build a wrapper for doSomethingAsync
that gives you a promise and do the below...)
If doSomethingAsync
gives you a Promise, if you can use ES2017+ syntax (perhaps with a transpiler like Babel), you can use an async
function with for-of
and await
:
async function doSomethingWith(theArray) {
const results = [];
for (const entry of theArray) {
results.push(await doSomethingAsync(entry));
}
return results;
}
doSomethingWith(theArray).then(results => {
console.log("Results:", results);
});
Example:
async function doSomethingWith(theArray) {_x000D_
const results = [];_x000D_
for (const entry of theArray) {_x000D_
results.push(await doSomethingAsync(entry));_x000D_
}_x000D_
return results;_x000D_
}_x000D_
doSomethingWith([1, 2, 3]).then(function(results) {_x000D_
console.log("Results:", results);_x000D_
});_x000D_
_x000D_
function doSomethingAsync(value) {_x000D_
console.log("Starting async operation for " + value);_x000D_
return new Promise(function(resolve) {_x000D_
setTimeout(function() {_x000D_
console.log("Completing async operation for " + value);_x000D_
resolve(value * 2);_x000D_
}, Math.floor(Math.random() * 200));_x000D_

If you can't use ES2017+ syntax (yet), you can use a variation on the "Promise reduce" pattern (this is more complex than the usual Promise reduce because we're not passing the result from one into the next, but instead gathering up their results in an array):
function doSomethingWith(theArray) {
return theArray.reduce(function(p, entry) {
return p.then(function(results) {
return doSomethingAsync(entry).then(function(result) {
results.push(result);
return results;
});
});
}, Promise.resolve([]));
}
doSomethingWith(theArray).then(function(results) {
console.log("Results:", results);
});
Example:
function doSomethingWith(theArray) {_x000D_
return theArray.reduce(function(p, entry) {_x000D_
return p.then(function(results) {_x000D_
return doSomethingAsync(entry).then(function(result) {_x000D_
results.push(result);_x000D_
return results;_x000D_
});_x000D_
});_x000D_
}, Promise.resolve([]));_x000D_
}_x000D_
doSomethingWith([1, 2, 3]).then(function(results) {_x000D_
console.log("Results:", results);_x000D_
});_x000D_
_x000D_
function doSomethingAsync(value) {_x000D_
console.log("Starting async operation for " + value);_x000D_
return new Promise(function(resolve) {_x000D_
setTimeout(function() {_x000D_
console.log("Completing async operation for " + value);_x000D_
resolve(value * 2);_x000D_
}, Math.floor(Math.random() * 200));_x000D_

...which is less cumbersome with ES2015+ arrow functions:

return theArray.reduce((p, entry) => p.then(results => doSomethingAsync(entry).then(result => {
results.push(result);
return results;
})), Promise.resolve([]));
}
doSomethingWith(theArray).then(results => {
console.log("Results:", results);
});

function doSomethingWith(theArray) {_x000D_
return theArray.reduce((p, entry) => p.then(results => doSomethingAsync(entry).then(result => {_x000D_

The solution is very simple. git checkout <filename>
tries to check out file from the index, and therefore fails on merge.
What you need to do is (i.e. checkout a commit):
To checkout your own version you can use one of:
git checkout HEAD -- <filename>
or
git checkout --ours -- <filename>
(Warning!: If you are rebasing --ours
and --theirs
are swapped.)
or
git show :2:<filename> > <filename> # (stage 2 is ours)
To checkout the other version you can use one of:
git checkout test-branch -- <filename>
or
git checkout --theirs -- <filename>
or
git show :3:<filename> > <filename> # (stage 3 is theirs)
You would also need to run 'add' to mark it as resolved:
git add <filename>
Sudo over SSH passing a password, no tty required:
You can use sudo over ssh without forcing ssh to have a pseudo-tty (without the use of the ssh "-t" switch) by telling sudo not to require an interactive password and to just grab the password off stdin. You do this by using the "-S" switch on sudo. This makes sudo listen for the password on stdin, and stop listening when it sees a newline.
Example 1 - Simple Remote Command
In this example, we send a simple whoami
command:
$ ssh user@server cat \| sudo --prompt="" -S -- whoami << EOF
> <remote_sudo_password>
root
We're telling sudo not to issue a prompt, and to take its input from stdin. This makes the sudo password passing completely silent so the only response you get back is the output from whoami
.
This technique has the benefit of allowing you to run programs through sudo over ssh that themselves require stdin input. This is because sudo is consuming the password over the first line of stdin, then letting whatever program it runs continue to grab stdin.
Example 2 - Remote Command That Requires Its Own stdin
In the following example, the remote command "cat" is executed through sudo, and we are providing some extra lines through stdin for the remote cat to display.
$ ssh user@server cat \| sudo --prompt="" -S -- "cat" << EOF
> <remote_sudo_password>
> Extra line1
> Extra line2
> EOF
Extra line1
Extra line2
The output demonstrates that the <remote_sudo_password>
line is being consumed by sudo, and that the remotely executed cat is then displaying the extra lines.
An example of where this would be beneficial is if you want to use ssh to pass a password to a privileged command without using the command line. Say, if you want to mount a remote encrypted container over ssh.
Example 3 - Mounting a Remote VeraCrypt Container
In this example script, we are remotely mounting a VeraCrypt container through sudo without any extra prompting text:
#!/bin/sh
ssh user@server cat \| sudo --prompt="" -S -- "veracrypt --non-interactive --stdin --keyfiles=/path/to/test.key /path/to/test.img /mnt/mountpoint" << EOF
SudoPassword
VeraCryptContainerPassword
EOF
It should be noted that in all the command-line examples above (everything except the script) the << EOF
construct on the command line will cause the everything typed, including the password, to be recorded in the local machine's .bash_history. It is therefore highly recommended that for real-world use you either use do it entirely through a script, like the veracrypt example above, or, if on the command line then put the password in a file and redirect that file through ssh.
Example 1a - Example 1 Without Local Command-Line Password
The first example would thus become:
$ cat text_file_with_sudo_password | ssh user@server cat \| sudo --prompt="" -S -- whoami
root
Example 2a - Example 2 Without Local Command-Line Password
and the second example would become:
$ cat text_file_with_sudo_password - << EOF | ssh va1der.net cat \| sudo --prompt="" -S -- cat
> Extra line1
> Extra line2
> EOF
Extra line1
Extra line2
Putting the password in a separate file is unnecessary if you are putting the whole thing in a script, since the contents of scripts do not end up in your history. It still may be useful, though, in case you want to allow users who should not see the password to execute the script.
You can also use
cd %localhost%
to set the directory to the folder the batch file was opened from. Your script would look like this:
@echo off
cd %localhost%
echo .> dblank.txt
Make sure you set the directory before you use the command to create the text file.
In my case .
The layout i was trying to inflate had
<include
layout = "...."

tag, removing it fixed it.
I was trying to inflate a previous layout designed for a Actvity into the view-pager adapter.
Maybe someone will think of a clever way to do this, but you shouldn't. Swapping two items in a list is inherently side-effect laden but LINQ operations should be side-effect free. Thus, just use a simple extension method:
static class IListExtensions {
public static void Swap<T>(
this IList<T> list,
int firstIndex,
int secondIndex
) {
Contract.Requires(list != null);
Contract.Requires(firstIndex >= 0 && firstIndex < list.Count);
Contract.Requires(secondIndex >= 0 && secondIndex < list.Count);
if (firstIndex == secondIndex) {
return;
}
T temp = list[firstIndex];
list[firstIndex] = list[secondIndex];
list[secondIndex] = temp;
}
}

Arrays are, in general, a poor data structure to use if you want to ask if a particular object is in the collection or not.
If you'll be running this search frequently, it might be worth it to use a Dictionary<string, something>
rather than an array. Lookups in a Dictionary are O(1) (constant-time), while searching through the array is O(N) (takes time proportional to the length of the array).
Even if the array is only 200 items at most, if you do a lot of these searches, the Dictionary will likely be faster.

$("#textbox1").prop("disabled", true);
$("#checkbox1").prop("disabled", true);

else {
$("#textbox1").prop("disabled", false);
$("#checkbox1").prop("disabled", false);

An AnyCPU assembly will JIT to 64-bit code when loaded into a 64-bit process and 32 bit when loaded into a 32-bit process.
By limiting the CPU you would be saying: There is something being used by the assembly (something likely unmanaged) that requires 32 bits or 64 bits.
I found that I can do some basic logic by running something like:
A=true
B=true
if ($A && $B); then
C=true
else
C=false

I'm not sure why is this not an answer already, but I just followed this advice and it worked.
Another solution involves creating mutable string:
//make mutable string
NSMutableString *stringToTrim = [@" i needz trim " mutableCopy];
//pass it by reference to CFStringTrimSpace
CFStringTrimWhiteSpace((__bridge CFMutableStringRef) stringToTrim);
//stringToTrim is now "i needz trim"
if(data.length==0){
alert("empty");
$('#MembershipTable > tbody').empty();
// $('#MembershipTable').dataTable().fnDestroy();
$('#MembershipTable_info').empty();
$("#MembershipTable_length").empty();
$("#MembershipTable_paginate").empty();
html="<tr><td colspan='20'><b>No data available in Table</b> </td></tr>";
$("#MembershipTable").append(html);
}
else{
$('#MembershipTable').dataTable().fnDestroy();
$('#MembershipTable > tbody').empty();
for(var i=0; i<data.length; i++){
//
.......}
I know this is old but it is still relevant. You can take advantage of reshape2::melt to change the dataframe into a more friendly structure for ggplot2.
Advantages:
Disadvantage:
For example:
jobsAFAM1 <- data.frame(
data_date = seq.Date(from = as.Date('2017-01-01'),by = 'day', length.out = 100),
Percent.Change = runif(5,1,100)
)
jobsAFAM2 <- data.frame(
data_date = seq.Date(from = as.Date('2017-01-01'),by = 'day', length.out = 100),
Percent.Change = runif(5,1,100)
)
jobsAFAM <- merge(jobsAFAM1, jobsAFAM2, by="data_date")
jobsAFAMMelted <- reshape2::melt(jobsAFAM, id.var='data_date')
ggplot(jobsAFAMMelted, aes(x=data_date, y=value, col=variable)) + geom_line()
Even more so, to add on the existing answers, you may use a macro that hides a struct initializer:
#define DEFAULT_EMPLOYEE { 0, "none" }
Then in your code:
employee john = DEFAULT_EMPLOYEE;
You can iterate through the entries in a Map
in several ways. Get each key and value like this:
Map<?,?> map = new HashMap<Object, Object>();
for(Entry<?, ?> e: map.entrySet()){
System.out.println("Key " + e.getKey());
System.out.println("Value " + e.getValue());
}
Or you can get the list of keys with
Collection<?> keys = map.keySet();
for(Object key: keys){
System.out.println("Key " + key);
System.out.println("Value " + map.get(key));
}
If you just want to get all of the values and aren't concerned with the keys, you can use:
Collection<?> values = map.values();
Here's another solution to retrieving the records only with a field that has the maximum value for that field. This works for SQL400 which is the platform I work on. In this example, the records with the maximum value in field FIELD5 will be retrieved by the following SQL statement.
SELECT A.KEYFIELD1, A.KEYFIELD2, A.FIELD3, A.FIELD4, A.FIELD5
FROM MYFILE A
WHERE RRN(A) IN
(SELECT RRN(B)
FROM MYFILE B
WHERE B.KEYFIELD1 = A.KEYFIELD1 AND B.KEYFIELD2 = A.KEYFIELD2
ORDER BY B.FIELD5 DESC
FETCH FIRST ROW ONLY)
Firstly — I don't think column1 is not NULL or column1 <> ''
makes very much sense. Maybe you meant to write column1 is not NULL and column1 <> ''
(AND
instead of OR
)?
Secondly — because of Hive's "schema on read" approach to table definitions, invalid values will be converted to NULL
when you read from them. So, for example, if table1.column1
is of type STRING
and table2.column1
is of type INT
, then I don't think that table1.column1 IS NOT NULL
is enough to guarantee that table2.column1 IS NOT NULL
. (I'm not sure about this, though.)
Use flatMap. If a value is present, flatMap returns a sequential Stream containing only that value, otherwise returns an empty Stream. So there is no need to use ifPresent()
. Example:
list.stream().map(data -> data.getSomeValue).map(this::getOptinalValue).flatMap(Optional::stream).collect(Collectors.toList());
For anyone using entity framework core ending up here. This is how you do it.
# Powershell / Package manager console
Script-Migration
# Cli
dotnet ef migrations script
You can use the -From
and -To
parameter to generate an update script to update a database to a specific version.
Script-Migration -From 20190101011200_Initial-Migration -To 20190101021200_Migration-2
https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/#generate-sql-scripts
There are several options to this command.
The from migration should be the last migration applied to the database before running the script. If no migrations have been applied, specify
0
(this is the default).The to migration is the last migration that will be applied to the database after running the script. This defaults to the last migration in your project.
An idempotent script can optionally be generated. This script only applies migrations if they haven't already been applied to the database. This is useful if you don't exactly know what the last migration applied to the database was or if you are deploying to multiple databases that may each be at a different migration.
Of course, you have to use to tags to do that. One to create the circle and other for the text.
Here some code may help you
#circle {
background: #f00;
width: 200px;
height: 200px;
border-radius: 50%;
color:black;
}
.innerTEXT{
position:absolute;
top:80px;
left:60px;
}
<div id="circle">
<span class="innerTEXT"> Here a text</span>
</div>
Live example here http://jsbin.com/apumik/1/edit
Update
Here less smaller with a few changes
Could you try something like this:
.red:first-of-type {
border: 5px solid red;
}
you also can use this for last element (if you need it):
.red:last-of-type {
border: 5px solid red;
}
This may also happen if you have a faulty or accidental equation in your csv file. i.e - One of the cells in your csv file starts with an equals sign (=) (An excel equation) which will, in turn throw an error. If you fix, or remove this equation by getting rid of the equals sign, it should solve the ORA-06502 error.
You can use the border-radius attribute to give it a border-radius equivalent to the element's border-radius. For example:
<div style="border-radius 10px; -moz-border-radius 10px; -webkit-border-radius 10px; width: 20px; height: 20px; background: red; border: solid black 1px;"> </div>
(The reason for using the -moz and -webkit extensions is to support pre-CSS3-final versions of Gecko and Webkit.)
There are more examples on this page. As far as inserting text, you can do it but you have to be mindful of the positioning, as most browsers' box padding model still uses the outer square.
setprecision(n)
applies to the entire number, not the fractional part. You need to use the fixed-point format to make it apply to the fractional part: setiosflags(ios::fixed)
Be careful with your routes. A "redirectTo" will remove|drop any query parameter.
const appRoutes: Routes [
{path: "one", component: PageOneComponent},
{path: "two", component: PageTwoComponent},
{path: "", redirectTo: "/one", pathMatch: full},
{path: "**", redirectTo: "/two"}
]
I called my main component with query parameters like "/main?param1=a¶m2=b and assume that my query parameters arrive in the "ngOnInit()" method in the main component before the redirect forwarding takes effect.
But this is wrong. The redirect will came before, drop the query parameters away and call the ngOnInit() method in the main component without query parameters.
I changed the third line of my routes to
{path: "", component: PageOneComponent},
and now my query parameters are accessible in the main components ngOnInit and also in the PageOneComponent.
$today=date('d-m-Y');
$next_date= date('d-m-Y', strtotime($today. ' + 90 days'));
echo $next_date;

Finally I got! Just to share, there are more config than just .env
This is .env
MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=********
MAIL_ENCRYPTION=tls
config/mail.php also need to input address & name for it to work.
'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'smtp.gmail.com'),
'port' => env('MAIL_PORT', 587),
'from' => ['address' => '[email protected]' , 'name' => 'YourName' ],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'sendmail' => '/usr/sbin/sendmail -bs',
'pretend' => false,
Join the table with itself and give it two different aliases (A
and B
in the following example). This allows to compare different rows of the same table.
SELECT DISTINCT A.Id
FROM
Address A
INNER JOIN Address B
ON A.Id = B.Id AND A.[Adress Code] < B.[Adress Code]
WHERE
A.Address <> B.Address
The "less than" comparison <
ensures that you get 2 different addresses and you don't get the same 2 address codes twice. Using "not equal" <>
instead, would yield the codes as (1, 2) and (2, 1); each one of them for the A
alias and the B
alias in turn.
The join clause is responsible for the pairing of the rows where as the where-clause tests additional conditions.
The query above works with any address codes. If you want to compare addresses with specific address codes, you can change the query to
SELECT A.Id
FROM
Address A
INNER JOIN Address B
ON A.Id = B.Id
WHERE
A.[Adress Code] = 1 AND
B.[Adress Code] = 2 AND
A.Address <> B.Address
I imagine that this might be useful to find customers having a billing address (Adress Code = 1 as an example) differing from the delivery address (Adress Code = 2) .
Loosely:
Declarative programming tends towards:-
Imperative programming tends towards:-
As a result, an imperative style helps the reader to understand the mechanics of what the system is actually doing, but may give little insight into the problem that it is intended to solve. On the other hand, a declarative style helps the reader to understand the problem domain and the approach that the system takes towards the solution of the problem, but is less informative on the matter of mechanics.
Real programs (even ones written in languages that favor the ends of the spectrum, such as ProLog or C) tend to have both styles present to various degrees at various points, to satisfy the varying complexities and communication needs of the piece. One style is not superior to the other; they just serve different purposes, and, as with many things in life, moderation is key.
BTW, in my case it was that I needed to specify the user/pwd in the url, not as independent properties, they were ignored and my OS user was used to connect

you must change your model name first letter capital. in localhost small letter work properly but online this not work. for exa:
common_model.php
replaced it to

You don't add or link directly against a DLL, you link against the LIB produced by the DLL.
A LIB provides symbols and other necessary data to either include a library in your code (static linking) or refer to the DLL (dynamic linking).
To link against a LIB, you need to add it to the project Properties -> Linker -> Input -> Additional Dependencies list. All LIB files here will be used in linking. You can also use a pragma like so:
#pragma comment(lib, "dll.lib")
With static linking, the code is included in your executable and there are no runtime dependencies. Dynamic linking requires a DLL with matching name and symbols be available within the search path (which is not just the path or system directory).
You could code an ES5.1 helper function:
function setAttributes(el, attrs) {
Object.keys(attrs).forEach(key => el.setAttribute(key, attrs[key]));
}
Call it like this:
setAttributes(elem, { src: 'http://example.com/something.jpeg', height: '100%' });

Your class:
class name {
public:
string first;
string last;
name() { } //Default constructor.
name(string a, string b){
first = a;
last = b;
}
};
Has an explicit constructor that requires two string parameters. Classes with no constructor written explicitly get default constructors taking no parameters. Adding the explicit one stopped the compiler from generating that default constructor for you.
So, if you wish to make an array of uninitialized objects, add a default constructor to your class so the compiler knows how to create them without providing those two string parameters - see the commented line above.

Here's the GNU version of printf
... you can see it passing in stdout
to vfprintf
:
__printf (const char *format, ...)
{
va_list arg;
int done;
va_start (arg, format);
done = vfprintf (stdout, format, arg);
va_end (arg);
return done;
}
Here's a link to vfprintf
... all the formatting 'magic' happens here.
The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf
equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)
Who ever is using LATEST, please make sure you have -U otherwise the latest snapshot won't be pulled.
mvn -U dependency:copy -Dartifact=com.foo:my-foo:LATEST
// pull the latest snapshot for my-foo from all repositories
$this->where('email', $email)->where('password', $password)
is returning a Builder object which you could use to append more where filters etc.
To get the result you need:
$userRecord = $this->where('email', $email)->where('password', $password)->first();
=AND(LEN($A1), COLUMN()<3, COUNTBLANK($E1:$H1))
=AND(LEN($A1), OR(COLUMN()<3, AND(COLUMN()>4, COUNTBLANK(A1))), COUNTBLANK($E1:$H1))
=$A:$H
.Results should be similar to the following.
¹ The COUNTBLANK function was introduced with Excel 2007. It will count both true blanks and zero-length strings left by formulas (e.g. ""
).
Use CSS Pseudo-classes and give your tag a class, for example:
<a class="noDecoration" href="#">
and add this to your stylesheet:
.noDecoration, a:link, a:visited {
text-decoration: none;
}
creating a symbolic link was the solution for me either. However before working I had to grant access and execute rights to the created symbolic links.
I am not sure if it was @eaykin's answer or @crazymacleod's that worked for me, as I did both before finding the above mentioned solution.
Thanks!
No, there isn't a syntax for extracting text using regular expressions. You have to use the ordinary string manipulation functions.
Alternatively select the entire value from the database (or the first n characters if you are worried about too much data transfer) and then use a regular expression on the client.
I had the same problem. I'm no expert but this is the solution we used: Before you filter your data, first create a temporary column to populate your entire data set with your original sort order. Auto number the temporary "original sort order" column. Now filter your data. Copy and paste the filtered data into a new worksheet. This will move only the filtered data to the new sheet so that your row numbers will become consecutive. Now auto number your desired field. Go back to your original worksheet and delete the filtered rows. Copy and paste the newly numbered data from the secondary sheet onto the bottom of your original worksheet. Then clear your filter and sort the worksheet by the temporary "original sort order" column. This will put your newly numbered data back into its original order and you can then delete the temporary column.
I use the header(name, value) method and give the return to webResource var:
Client client = Client.create();
WebResource webResource = client.resource("uri");
MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl();
queryParams.add("json", js); //set parametes for request
appKey = "Bearer " + appKey; // appKey is unique number
//Get response from RESTful Server get(ClientResponse.class);
ClientResponse response = webResource.queryParams(queryParams)
.header("Content-Type", "application/json;charset=UTF-8")
.header("Authorization", appKey)
.get(ClientResponse.class);
String jsonStr = response.getEntity(String.class);

You need to put the font files in assets folder (may be a fonts sub-folder within assets) and refer to it in the styles:
@font-face {
font-family: lato;
src: url(assets/font/Lato.otf) format("opentype");
}
Once done, you can apply this font any where like:
* {
box-sizing: border-box;
margin: 0;
padding: 0;
font-family: 'lato', 'arial', sans-serif;
}
You can put the @font-face
definition in your global styles.css
or styles.scss
and you would be able to refer to the font anywhere - even in your component specific CSS/SCSS. styles.css
or styles.scss
is already defined in angular-cli.json
. Or, if you want you can create a separate CSS/SCSS file and declare it in angular-cli.json along with the styles.css
or styles.scss
like:
"styles": [
"styles.css",
"fonts.css"
],
You can also load the content with cURL, if file_get_contents insn't enabled on your server.
Example:
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://feeds.bbci.co.uk/sport/0/football/rss.xml?edition=int");
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$output = curl_exec($ch);
curl_close($ch);
$items = simplexml_load_string($output);
<input type="text" id="inputName" placeholder="Enter name" required oninvalid="this.setCustomValidity('Your Message')" oninput="this.setCustomValidity('') />
this can help you even more better, Fast, Convenient & Easiest.
You can sum numbers in a list simply with the sum() built-in:
sum(your_list)
It will sum as many number items as you have. Example:
my_list = range(10, 17)
my_list
[10, 11, 12, 13, 14, 15, 16]
sum(my_list)
91
For your specific case:
For your data convert the numbers into int
first and then sum the numbers:
data = ['5', '4', '9']
sum(int(i) for i in data)
18
This will work for undefined number of elements in your list (as long as they are "numbers")
Thanks for @senderle's comment re conversion in case the data is in string format.
In general, things are easier to keep organized if you separate your code and your markup. Define all of your elements, and then in your JavaScript section, define the various actions that should be performed on those elements.
When an event handler is called, it's called within the context of the element that was clicked on. So, the identifier this will refer to the DOM element that you clicked on. You can then access attributes of the element through that identifier.
For example:
<button id="1">Button 1</button>
<button id="2">Button 2</button>
<button id="3">Button 3</button>
<script type="text/javascript">
var reply_click = function()
{
alert("Button clicked, id "+this.id+", text"+this.innerHTML);
}
document.getElementById('1').onclick = reply_click;
document.getElementById('2').onclick = reply_click;
document.getElementById('3').onclick = reply_click;
</script>
sp_change_users_login
is deprecated.
Much easier is:
ALTER USER usr1 WITH LOGIN = login1;
I have found an excellent and relatively short explanation here.
A multipart request is a REST request containing several packed REST requests inside its entity.
SerialPort (RS-232 Serial COM Port) in C# .NET
This article explains how to use the SerialPort
class in .NET to read and write data, determine what serial ports are available on your machine, and how to send files. It even covers the pin assignments on the port itself.
Example Code:
using System;
using System.IO.Ports;
using System.Windows.Forms;
namespace SerialPortExample
{
class SerialPortProgram
{
// Create the serial port with basic settings
private SerialPort port = new SerialPort("COM1",
9600, Parity.None, 8, StopBits.One);
[STAThread]
static void Main(string[] args)
{
// Instatiate this class
new SerialPortProgram();
}
private SerialPortProgram()
{
Console.WriteLine("Incoming Data:");
// Attach a method to be called when there
// is data waiting in the port's buffer
port.DataReceived += new
SerialDataReceivedEventHandler(port_DataReceived);
// Begin communications
port.Open();
// Enter an application loop to keep this thread alive
Application.Run();
}
private void port_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
// Show all the incoming data in the port's buffer
Console.WriteLine(port.ReadExisting());
}
}
}
Use sprintf
(or snprintf
if like me you can't count) with format string "pre_%d_suff"
.
For what it's worth, with itoa/strcat you could do:
char dst[12] = "pre_";
itoa(i, dst+4, 10);
strcat(dst, "_suff");
Why not just use rm -rf /some/dir
? That will remove the directory if it's present, otherwise do nothing. Unlike rm -r /some/dir
this flavor of the command won't crash if the folder doesn't exist.
You can just use a UNIX pipe for this
brew deps [FORMULA] | xargs brew rm
I had the same question but applying the provided solutions changed the file to write in. Once I selected the new excel file, I was also writing in that file and not in my original file. My solution for this issue is below:
Sub GetData()
Dim excelapp As Application
Dim source As Workbook
Dim srcSH1 As Worksheet
Dim sh As Worksheet
Dim path As String
Dim nmr As Long
Dim i As Long
nmr = 20
Set excelapp = New Application
With Application.FileDialog(msoFileDialogOpen)
.AllowMultiSelect = False
.Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
.Show
path = .SelectedItems.Item(1)
End With
Set source = excelapp.Workbooks.Open(path)
Set srcSH1 = source.Worksheets("Sheet1")
Set sh = Sheets("Sheet1")
For i = 1 To nmr
sh.Cells(i, "A").Value = srcSH1.Cells(i, "A").Value
Next i
End Sub
With excelapp
a new application will be called. The with
block sets the path for the external file. Finally, I set the external Workbook with source
and srcSH1
as a Worksheet within the external sheet.
You might want to look at Liquibase (http://www.liquibase.org/). Even if you don't use the tool itself it handles the concepts of database change management or refactoring pretty well.
This is more for someone Searching for a result, than the original post-er. This worked for me...
declare @value varchar(max) = 'sad';
select sum(cast(iif(isnumeric(@value) = 1, @value, 0) as bigint));
returns 0
declare @value varchar(max) = '3';
select sum(cast(iif(isnumeric(@value) = 1, @value, 0) as bigint));
returns 3
Here are some other approaches you can take.
1. CTE with union:
;WITH cte AS (SELECT a, b, c FROM table1)
SELECT a AS val FROM cte
UNION SELECT b AS val FROM cte
UNION SELECT c AS val FROM cte;
2. CTE with unpivot:
;WITH cte AS (SELECT a, b, c FROM table1)
SELECT DISTINCT val
FROM cte
UNPIVOT (val FOR col IN (a, b, c)) u;
You will need to configure you IIS (assuming this is the web server your are/will using) allowing access from WLAN/LAN to specific users (or anonymous). Allow IIS trought your firewall if you have one.
Your application won't need to be changed, that's just networking problems ans configuration you will have to face to allow acces only trought LAN and WLAN.
Following is the util function to get current timestamp in milliseconds:
#include <sys/time.h>
long long current_timestamp() {
struct timeval te;
gettimeofday(&te, NULL); // get current time
long long milliseconds = te.tv_sec*1000LL + te.tv_usec/1000; // calculate milliseconds
// printf("milliseconds: %lld\n", milliseconds);
return milliseconds;
}
About timezone:
gettimeofday() support to specify timezone, I use NULL, which ignore the timezone, but you can specify a timezone, if need.
@Update - timezone
Since the long
representation of time is not relevant to or effected by timezone itself, so setting tz
param of gettimeofday() is not necessary, since it won't make any difference.
And, according to man page of gettimeofday()
, the use of the timezone
structure is obsolete, thus the tz
argument should normally be specified as NULL, for details please check the man page.
Works for me:
std::wstring CStringToWString(const CString& s)
{
std::string s2;
s2 = std::string((LPCTSTR)s);
return std::wstring(s2.begin(),s2.end());
}
CString WStringToCString(std::wstring s)
{
std::string s2;
s2 = std::string(s.begin(),s.end());
return s2.c_str();
}

Here's a variation of @RichieHindle's excellent answer which implements a decorator that can be selectively applied to functions as desired. Works with Python 2.7.14 and 3.6.4.
from __future__ import print_function
import functools
import traceback
import sys
INDENT = 4*' '
def stacktrace(func):
@functools.wraps(func)
def wrapped(*args, **kwds):
# Get all but last line returned by traceback.format_stack()
# which is the line below.
callstack = '\n'.join([INDENT+line.strip() for line in traceback.format_stack()][:-1])
print('{}() called:'.format(func.__name__))
print(callstack)
return func(*args, **kwds)
return wrapped
@stacktrace
def test_func():
return 42
print(test_func())
Output from sample:
test_func() called:
File "stacktrace_decorator.py", line 28, in <module>
print(test_func())
42
Try this:
function someFunction(username, password) {
return new Promise((resolve, reject) => {
// Do something with the params username and password...
if ( /* everything turned out fine */ ) {
resolve("Stuff worked!");
} else {
reject(Error("It didn't work!"));
}
});
}
someFunction(username, password)
.then((result) => {
// Do something...
})
.catch((err) => {
// Handle the error...
});

Are you asking in php or javascript.
If it is in php, give the name of that and use the post or get method, after that you can use the option of isset or that particular button name is checked to that value.
If it is in js, use getElementById for that
If you use bpython, all your command history is by default saved to ~/.pythonhist
.
To save the commands for later reusage you can copy them to a python script file:
$ cp ~/.pythonhist mycommands.py
Then edit that file to clean it up and put it under Python path (global or virtual environment's site-packages, current directory, mentioning in *.pth, or some other way).
To include the commands into your shell, just import them from the saved file:
>>> from mycommands import *
It's a difference between RDBMS's varchar
(or similar) — those are usually specified with a maximum length, and might be more efficient in terms of performance or storage — and text
(or similar) types — those are usually limited only by hardcoded implementation limits (not a DB schema).
PostgreSQL 9, specifically, states that "There is no performance difference among these three types", but AFAIK there are some differences in e.g. MySQL, so this is something to keep in mind.
A good rule of thumb is that you use CharField
when you need to limit the maximum length, TextField
otherwise.
This is not really Django-specific, also.
I had the same issue too, the problem is exacerbated with the download link now only working for Visual Studio 2017, and installing the package from the download link did nothing for VS2015, although it took up 5gB of space.
I looked everywhere on how to do it with the Nu Get package manager and I couldn't find the solution.
It turns out it's even simpler than that, all you have to do is right-click the project or solution in the Solution Explorer from within Visual Studio, and click "Install Missing Components"
You have to return a promise instead of a variable. So in your function just return:
return relationsManagerResource.GetParentId(nodeId)
And later resolve the returned promise.
Or you can make another deferred and resolve theParentId
with it.
in pyqt5 to convert from a ui file to .py file
pyuic5.exe youruifile.ui -o outputpyfile.py -x
You're close.
std::list<Student>::iterator it;
for (it = data.begin(); it != data.end(); ++it){
std::cout << it->name;
}
Note that you can define it
inside the for
loop:
for (std::list<Student>::iterator it = data.begin(); it != data.end(); ++it){
std::cout << it->name;
}
And if you are using C++11 then you can use a range-based for
loop instead:
for (auto const& i : data) {
std::cout << i.name;
}
Here auto
automatically deduces the correct type. You could have written Student const& i
instead.
If you need to remove unbreakable spaces too, you can upgrade your code like this :
st.replaceAll("[\\s|\\u00A0]+", "");
Strangely enough,
package main
func main () {
var sessions = map[string] chan int{};
delete(sessions, "moo");
}
seems to work. This seems a poor use of resources though!
Another way is to check for existence and use the value itself:
package main
func main () {
var sessions = map[string] chan int{};
sessions["moo"] = make (chan int);
_, ok := sessions["moo"];
if ok {
delete(sessions, "moo");
}
}
It looks like you want to define Truck as a Class
with properties NumberOfAxles, AxleWeights & AxleSpacings.
This can be defined in a CLASS MODULE (here named clsTrucks)
Option Explicit
Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double
Public Property Get truckID() As String
truckID = tID
End Property
Public Property Let truckID(value As String)
tID = value
End Property
Public Property Get truckNumberOfAxles() As Double
truckNumberOfAxles = tNumberOfAxles
End Property
Public Property Let truckNumberOfAxles(value As Double)
tNumberOfAxles = value
End Property
Public Property Get truckAxleSpacings() As Double
truckAxleSpacings = tAxleSpacings
End Property
Public Property Let truckAxleSpacings(value As Double)
tAxleSpacings = value
End Property
then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.
Option Explicit
Public TruckCollection As New Collection
Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long
'Add 5 trucks
For i = 1 To 5
Set tempTruck = New clsTrucks
'Random data
tempTruck.truckID = "Truck" & i
tempTruck.truckAxleSpacings = 13.5 + i
tempTruck.truckNumberOfAxles = 20.5 + i
'tempTruck.truckID is the collection key
TruckCollection.Add tempTruck, tempTruck.truckID
Next i
'retrieve 5 trucks
For i = 1 To 5
'retrieve by collection index
Debug.Print TruckCollection(i).truckAxleSpacings
'retrieve by key
Debug.Print TruckCollection("Truck" & i).truckAxleSpacings
Next i
End Sub
There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.
URLs use forward slashes (/), not backward ones (as windows). Try:
serverURLS = "https://abc.my.domain.com:55555/update";
The reason why you get the error is that the URL class can't parse the host part of the string and therefore, host
is null
.
You can simply do this:
user.js
class User {
//...
}
module.exports = User
server.js
const User = require('./user.js')
// Instantiate User:
let user = new User()
This is called CommonJS module.
Sometimes it could be useful to export more than one value. For example it could be classes, functions or constants. This is an alternative version of the same functionality:
user.js
class User {}
exports.User = User // Spot the difference
server.js
const {User} = require('./user.js') // Destructure on import
// Instantiate User:
let user = new User()
Since Node.js version 14 it's possible to use ES Modules with CommonJS. Read more about it in the ESM documentation.
?? Don't use globals, it creates potential conflicts with the future code.
I am an iOS dev, so I made a solution similar to NotificationCenter:
object NotificationCenter {
var observers: MutableMap<String, MutableList<NotificationObserver>> = mutableMapOf()
fun addObserver(observer: NotificationObserver, notificationName: NotificationName) {
var os = observers[notificationName.value]
if (os == null) {
os = mutableListOf<NotificationObserver>()
observers[notificationName.value] = os
}
os.add(observer)
}
fun removeObserver(observer: NotificationObserver, notificationName: NotificationName) {
val os = observers[notificationName.value]
if (os != null) {
os.remove(observer)
}
}
fun removeObserver(observer:NotificationObserver) {
observers.forEach { name, mutableList ->
if (mutableList.contains(observer)) {
mutableList.remove(observer)
}
}
}
fun postNotification(notificationName: NotificationName, obj: Any?) {
val os = observers[notificationName.value]
if (os != null) {
os.forEach {observer ->
observer.onNotification(notificationName,obj)
}
}
}
}
interface NotificationObserver {
fun onNotification(name: NotificationName,obj:Any?)
}
enum class NotificationName(val value: String) {
onPlayerStatReceived("on player stat received"),
...
}
Some class that want to observe notification must conform to observer protocol:
class MainActivity : AppCompatActivity(), NotificationObserver {
override fun onCreate(savedInstanceState: Bundle?) {
...
NotificationCenter.addObserver(this,NotificationName.onPlayerStatReceived)
}
override fun onDestroy() {
...
super.onDestroy()
NotificationCenter.removeObserver(this)
}
...
override fun onNotification(name: NotificationName, obj: Any?) {
when (name) {
NotificationName.onPlayerStatReceived -> {
Log.d(tag, "onPlayerStatReceived")
}
else -> Log.e(tag, "Notification not handled")
}
}
Finally, post some notification to observers:
NotificationCenter.postNotification(NotificationName.onPlayerStatReceived,null)
According to this SO answer, it occurs due to an AWS SDK bug that appears to be solved in version 2.6.30 of the SDK, so updating the version to a newer, can help you fixing the problem.
The answers above work ($ for empty), but I just tried this and it also works to just leave empty like so:
/\A(INTENSE_EMAIL_REGEX|)\z/i
Same thing in reverse order
/\A(|INTENSE_EMAIL_REGEX)\z/i
In your controller use:
var path = HttpContext.Server.MapPath("~/Data/data.html");
This allows you to test the controller with Moq like so:
var queryString = new NameValueCollection();
var mockRequest = new Mock<HttpRequestBase>();
mockRequest.Setup(r => r.QueryString).Returns(queryString);
var mockHttpContext = new Mock<HttpContextBase>();
mockHttpContext.Setup(c => c.Request).Returns(mockRequest.Object);
var server = new Mock<HttpServerUtilityBase>();
server.Setup(m => m.MapPath("~/Data/data.html")).Returns("path/to/test/data");
mockHttpContext.Setup(m => m.Server).Returns(server.Object);
var mockControllerContext = new Mock<ControllerContext>();
mockControllerContext.Setup(c => c.HttpContext).Returns(mockHttpContext.Object);
var controller = new MyTestController();
controller.ControllerContext = mockControllerContext.Object;
Why don't you use cURL
?
$yourkey="your api key";
$url="https://prod.api.pvp.net/api/lol/euw/v1.1/game/by-summoner/20986461/recent?api_key=$yourkey";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$auth = curl_exec($curl);
if($auth)
{
$json = json_decode($auth);
print_r($json);

Use the CSS attribute "overflow" for this.
Short summary:
overflow: visible|hidden|scroll|auto|initial|inherit;
e.g.
table {
display: block;
overflow: scroll;
}
Look, instead of using visibility: hidden;
use display: none;
. The first option will hide but still takes space and the second option will hide and doesn't take any space.
Using dtype
will give you desired column's data type:
dataframe['column1'].dtype
if you want to know data types of all the column at once, you can use plural of dtype
as dtypes:
dataframe.dtypes
Conventions:
Tools:
Update: Since Python 3.5 you can use type hints which is a compact, machine-readable syntax:
from typing import Dict, Union
def foo(i: int, d: Dict[str, Union[str, int]]) -> int:
"""
Explanation: this function takes two arguments: `i` and `d`.
`i` is annotated simply as `int`. `d` is a dictionary with `str` keys
and values that can be either `str` or `int`.
The return type is `int`.
"""
The main advantage of this syntax is that it is defined by the language and that it's unambiguous, so tools like PyCharm can easily take advantage from it.
Pointing the source(src) folder to the build path will solve this easily to do so right click on the project > build path > configure build path > java build path > source > add folder and click Apply

This is on groovy, but I thing that this is not problem for you. Method work perfect.
Error messages don't get any clearer than this:
"Scripts may close only the windows that were opened by it."
If your script did not initiate opening the window (with something like window.open), then the script in that window is not allowed to close it. Its a security to prevent a website taking control of your browser and closing windows.
Not sure if this is the most efficient method, but it might be relatively interesting: the the Burrows-Wheeler transform. According to the WP article, all rotations of the input yield the same output. For applications such as compression this isn't desirable, so the original rotation is indicated (e.g. by an index; see the article). But for simple rotation-independent comparison, it sounds ideal. Of course, it's not necessarily ideally efficient!
You can use Object.getOwnPropertyNames()
to get all properties that belong to an object, whether enumerable or not. For example:
console.log(Object.getOwnPropertyNames(Math));
//-> ["E", "LN10", "LN2", "LOG2E", "LOG10E", "PI", ...etc ]
You can then use filter()
to obtain only the methods:
console.log(Object.getOwnPropertyNames(Math).filter(function (p) {
return typeof Math[p] === 'function';
}));
//-> ["random", "abs", "acos", "asin", "atan", "ceil", "cos", "exp", ...etc ]
In ES3 browsers (IE 8 and lower), the properties of built-in objects aren't enumerable. Objects like window
and document
aren't built-in, they're defined by the browser and most likely enumerable by design.
From ECMA-262 Edition 3:
Global Object
There is a unique global object (15.1), which is created before control enters any execution context. Initially the global object has the following properties:• Built-in objects such as Math, String, Date, parseInt, etc. These have attributes { DontEnum }.
• Additional host defined properties. This may include a property whose value is the global object itself; for example, in the HTML document object model the window property of the global object is the global object itself.As control enters execution contexts, and as ECMAScript code is executed, additional properties may be added to the global object and the initial properties may be changed.
I should point out that this means those objects aren't enumerable properties of the Global object. If you look through the rest of the specification document, you will see most of the built-in properties and methods of these objects have the { DontEnum }
attribute set on them.
Update: a fellow SO user, CMS, brought an IE bug regarding { DontEnum }
to my attention.
Instead of checking the DontEnum attribute, [Microsoft] JScript will skip over any property in any object where there is a same-named property in the object's prototype chain that has the attribute DontEnum.
In short, beware when naming your object properties. If there is a built-in prototype property or method with the same name then IE will skip over it when using a for...in
loop.

When you
import App from './App.jsx';
That means it will import whatever you export default
. You can rename App
class inside App.jsx
to whatever you want as long as you export default
it will work but you can only have one export default.
So you only need to export default App
and you don't need to export the rest.
If you still want to export the rest of the components, you will need named export.

I just had the same problem. Visual Studio isn't building the project that's being referenced.
CSS Attribute selectors will allow you to check attributes for a string. (in this case - a class-name)
https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors
(looks like it's actually at 'recommendation' status for 2.1 and 3)
Here's an outline of how I *think it works:
[ ]
: is the container for complex selectors if you will... class
: 'class' is the attribute you are looking at in this case.*
: modifier(if any): in this case - "wildcard" indicates you're looking for ANY match.test-
: the value (assuming there is one) of the attribute - that contains the string "test-" (which could be anything)So, for example:
[class*='test-'] {
color: red;
}
You could be more specific if you have good reason, with the element too
ul[class*='test-'] > li { ... }
I've tried to find edge cases, but I see no need to use a combination of ^
and *
- as * gets everything...
example: http://codepen.io/sheriffderek/pen/MaaBwp
http://caniuse.com/#feat=css-sel2
Everything above IE6 will happily obey. : )
note that:
[class] { ... }
Will select anything with a class...
I also got the message "The search key was not found in any record". When I moved my database from the network drive to my desktop, everything ran smoothly and faster. I didn't get the same error again.

You can also use python chardet library
# install the chardet library
!pip install chardet
# import the chardet library
import chardet
# use the detect method to find the encoding
# 'rb' means read in the file as binary
with open("test.csv", 'rb') as file:
print(chardet.detect(file.read()))
what happened to me is that I have multiple projects in my solution. I meant to debug project 1, however, the project 2 was set as the default starting project. I fixed this by, right click on the project and select "Set as startup project", then running debugging is fine.
Nowdays that's possible with native JS
var href = new URL('https://google.com?q=cats');
href.searchParams.set('q', 'dogs');
console.log(href.toString()); // https://google.com/?q=dogs
You could also do it like this, not sure if it's a good plan :D
class Parent extends Component {
handleClick() {
if (this._getAlert !== null) {
this._getAlert()
}
}
render() {
return (
<div>
<Child>
{(getAlert, childScope) => (
<span> {!this._getAlert ? this._getAlert = getAlert.bind(childScope) : null}</span>
)}
</Child>
<button onClick={() => this.handleClick()}> Click me</button>
</div>
);
}
}
class Child extends Component {
constructor() {
super();
this.state = { count: 0 }
}
getAlert() {
alert(`Child function called state: ${this.state.count}`);
this.setState({ count: this.state.count + 1 });
}
render() {
return this.props.children(this.getAlert, this)
}
}

Your piece of script works just great. Are you sure you are not assigning anything else before the if to "i"?
A common mistake is also not to leave a space after and before the square brackets.
Just wondering why you are using 2 directives?
It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.
Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).
It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.
Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

You need to pass "departure_time":str(int(time.time()))
is a required query string parameter for traffic information.
Your traffic information would be present in duration_in_traffic
.

It works ! Now you can use a subprocess.run
to run this from python.
If you have the process ID (PID
) you can kill this process as follow:
Process processToKill = Process.GetProcessById(pid);
processToKill.Kill();
