(Posted on behalf of the OP).
I believe I figured it out.
In my case, I added [class*="col-"] {padding: 0 7.5px;};
.
Then added .row {margin: 0 -7.5px;}
.
This works pretty well, except there is 1px margin on both sides. So I just make .row {margin: 0 -7.5px;}
to .row {margin: 0 -8.5px;}
, then it works perfectly.
I have no idea why there is a 1px margin. Maybe someone can explain it?
See the sample I created:
If you use sass in your own project, you can override the default bootstrap gutter size by copy pasting the sass variables from bootstrap's _variables.scss file into your own projects sass file somewhere, like:
// Grid columns
//
// Set the number of columns and specify the width of the gutters.
$grid-gutter-width-base: 50px !default;
$grid-gutter-widths: (
xs: $grid-gutter-width-base,
sm: $grid-gutter-width-base,
md: $grid-gutter-width-base,
lg: $grid-gutter-width-base,
xl: $grid-gutter-width-base
) !default;
Now your gutters will be 50px instead of 30px. I find this to be the cleanest method to adjust the gutter size.

Try setting the charset on your Content-Type:
httpCon.setRequestProperty( "Content-Type", "multipart/form-data; charset=UTF-8; boundary=" + boundary );
If you can use some dynamic query, you can use LEN
. It will give false on both empty and null string. By this way you can implement the option parameter.
ALTER PROCEDURE [dbo].[psProducts]
(@SearchType varchar(50))
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Query nvarchar(max) = N'
SELECT
P.[ProductId],
P.[ProductName],
P.[ProductPrice],
P.[Type]
FROM [Product] P'
-- if @Searchtype is not null then use the where clause
SET @Query = CASE WHEN LEN(@SearchType) > 0 THEN @Query + ' WHERE p.[Type] = ' + ''''+ @SearchType + '''' ELSE @Query END
EXECUTE sp_executesql @Query
PRINT @Query
END
//source
public async Task<string> methodName()
{
return Data;
}
//Consumption
methodName().Result;
Hope this helps :)
In the repository directory you remove the directory named .git and that's all :). On Un*x it is hidden, so you might not see it from file browser, but
cd repository-path/
rm -r .git
should do the trick.
In my case it was Avast Antivirus interfering with the connection. Actions to disable this feature: Avast -> Settings-> Components -> Mail Shield (Customize) -> SSL scanning -> uncheck "Scan SSL connections".
import csv
hello = [['Me','You'],['293', '219'],['13','15']]

with open('test1.csv', 'wb') as testfile:
csv_writer = csv.writer(testfile)
for y in range(length):
csv_writer.writerow([x[y] for x in hello])
will produce an output like this

I had the same problem and it turned out that my image names included special characters (e.g. château.jpg), which could not bet handled by cv2.imread
. My solution was to make a temporary copy of the file, renaming it e.g. temp.jpg, which could be loaded by cv2.imread
without any problems.
Note: I did not check the performance of shutil.copy2
vice versa other options. So probably there is a better/faster solution to make a temporary copy.
import shutil, sys, os, dlib, glob, cv2
for f in glob.glob(os.path.join(myfolder_path, "*.jpg")):
shutil.copy2(f, myfolder_path + 'temp.jpg')
img = cv2.imread(myfolder_path + 'temp.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
os.remove(myfolder_path + 'temp.jpg')
If there are only few files with special characters, renaming can also be done as an exeption, e.g.
for f in glob.glob(os.path.join(myfolder_path, "*.jpg")):
try:
img = cv2.imread(f)
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
except:
shutil.copy2(f, myfolder_path + 'temp.jpg')
img = cv2.imread(myfolder_path + 'temp.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
os.remove(myfolder_path + 'temp.jpg')
The previous answers assume that you indeed calculated TP/Sens yourself. It's a bad idea to do this manually, it's easy to make mistakes with the calculations, rather use a library function for all of this.
the plot_roc function in scikit_lean does exactly what you need: http://scikit-learn.org/stable/auto_examples/model_selection/plot_roc.html
The essential part of the code is:
for i in range(n_classes):
fpr[i], tpr[i], _ = roc_curve(y_test[:, i], y_score[:, i])
roc_auc[i] = auc(fpr[i], tpr[i])
you can import django and then type print statement as given below to know the version of django i.e. installed on your system:

I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:
FOR /F "tokens=*" %G IN ('dir /b') DO robocopy "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0
As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.
It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.
Thanks for the answer of https://stackoverflow.com/a/65513726/889126, it gave me an idea to make a complete bash script as it is
export api_image_id=$(docker inspect --format="{{.Id}}" <image-name> | sed '/^[[:space:]]*$/d')
sudo docker exec -i -t ${api_image_id} /bin/bash
I need a specific container and make a script to extract some info from it in a quick sight.
Hope this would help others.
Try this in config.js
CKEDITOR.editorConfig = function( config )
{
config.enterMode = CKEDITOR.ENTER_BR;
config.shiftEnterMode = CKEDITOR.ENTER_BR;
};
Following will give you active connections/ queries in postgres DB-
SELECT
pid
,datname
,usename
,application_name
,client_hostname
,client_port
,backend_start
,query_start
,query
,state
FROM pg_stat_activity
WHERE state = 'active';
You may use 'idle' instead of active to get already executed connections/queries.

First Parse the json data by using jquery eval parser and then iterarate through jquery each function below is the code sniplet:
var obj = eval("(" + data.d + ")");
alert(obj);
$.each(obj, function (index,Object) {
var Id = Object.Id;
var AptYear = Object.AptYear;
$("#ddlyear").append('<option value=' + Id + '>' + AptYear + '</option>').toString();
});
On Server Server 2016 and newer, you can use STRING_SPLIT
with t as (
select 'GOOFYEAR Tire and Rubber Company' as n
union all
select 'THE HAPPY BEAR' as n
union all
select 'MONK HOUSE SALES' as n
union all
select 'FORUM COMMUNICATIONS' as n
)
select
n,
(
select ' ' + (
upper(left(value, 1))
+ lower(substring(value, 2, 999))
)
from (
select value
from string_split(t.n, ' ')
) as sq
for xml path ('')
) as title_cased

Junit xml format is used outside of Java/Maven/Ant word. Jenkins with http://wiki.jenkins-ci.org/display/JENKINS/xUnit+Plugin is a solution.
For the one shot solution I have found this tool that does the job: https://www.npmjs.com/package/junit-viewer
junit-viewer --results=surefire-reports --save=file_location.html
--results=
is directory with xml files (test reports)
For a PRIMARY KEY
, an index will be created with the following message:
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "index" for table "table"
For a FOREIGN KEY
, the constraint will not be created if there is no index on the referenced table.
An index on referencing table is not required (though desired), and therefore will not be implicitly created.
You are calling nextInt
statically by using Random.nextInt
.
Instead, create a variable, Random r = new Random();
and then call r.nextInt(10)
.
It would be definitely worth while to check out:
You really should replace this line,
Random Random = new Random();
with something like this,
Random r = new Random();
If you use variable names as class names you'll run into a boat load of problems. Also as a Java convention, use lowercase names for variables. That might help avoid some confusion.
I simply add the return key word like:
return res.redirect("/great");
and walla!
If you're using Ubuntu, run sudo apt install libssl-dev
.
Don't use localhost in the url!
Use like this:
<script type="text/javascript">
$("a.more").fancybox({
'titleShow' : false,
'transitionIn' : 'elastic',
'transitionOut' : 'elastic',
'href' : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
'type' : 'swf',
'swf' : {'wmode':'transparent','allowfullscreen':'true'}
});
</script>
This way if the user javascript is enabled it opens a fancybox with the youtube embed video, if javascript is disabled it opens the video's youtube page. If you want you can add
target="_blank"
to each of your links, it won't validate on most doctypes, but it will open the link in a new window if fancybox doesn't pick it up.
this
, above, isn't referenced correctly, so the code won't find href
under this
. You have to call it like this:
$("a.more").click(function() {
$.fancybox({
'padding' : 0,
'autoScale' : false,
'transitionIn' : 'none',
'transitionOut' : 'none',
'title' : this.title,
'width' : 680,
'height' : 495,
'href' : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
'type' : 'swf',
'swf' : {
'wmode' : 'transparent',
'allowfullscreen' : 'true'
}
});
return false;
});
as covered at http://fancybox.net/blog #4, replicated above
To obtain all the rows that contains an empty cell in in a particular column.
DF_new_row=DF_raw.loc[DF_raw['columnname']=='']
This will give the subset of DF_raw, which satisfy the checking condition.
I've been using this line to launch the default browser:

This ERROR can happen when you use Mockito to mock final classes.
Consider using Mockito inline or Powermock instead.
A normal loop?
function extend(target) {
var sources = [].slice.call(arguments, 1);
sources.forEach(function (source) {
for (var prop in source) {
target[prop] = source[prop];
}
});
return target;
}
var object3 = extend({}, object1, object2);
That's a basic starting point. You may want to add things like a hasOwnProperty
check, or add some logic to handle the case where multiple source objects have a property with the same identifier.
Here's a working example.
Side note: what you are referring to as "JSON" are actually normal JavaScript objects. JSON is simply a text format that shares some syntax with JavaScript.
This is working
<form name="myform" ng-submit="create()">
<input type="number"
name="price_field"
ng-model="price"
require
ng-pattern="/^\d{0,9}(\.\d{1,9})?$/">
<span ng-show="myform.price_field.$error.pattern">Not valid number!</span>
<input type="submit" class="btn">
</form>
A few ways:
-- Do the comparison, OR'd with a check on the @Country=0 case
WHERE (a.Country = @Country OR @Country = 0)
-- compare the Country field to itself
WHERE a.Country = CASE WHEN @Country > 0 THEN @Country ELSE a.Country END
Or, use a dynamically generated statement and only add in the Country condition if appropriate. This should be most efficient in the sense that you only execute a query with the conditions that actually need to apply and can result in a better execution plan if supporting indices are in place. You would need to use parameterised SQL to prevent against SQL injection.

This could be a issue in mvn home path in IntellijIdea IDE. For me it worked out when I set the mvn home directory correctly.
From the official documentation:
As of PHP 5.2.2, DateTime objects can be compared using comparison operators.
$date1 = new DateTime("now");
$date2 = new DateTime("tomorrow");
var_dump($date1 == $date2); // false
var_dump($date1 < $date2); // true
var_dump($date1 > $date2); // false
For PHP versions before 5.2.2 (actually for any version), you can use diff.
$datetime1 = new DateTime('2009-10-11'); // 11 October 2013
$datetime2 = new DateTime('2009-10-13'); // 13 October 2013
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days'); // +2 days

A slight edit on an example provided in http://matplotlib.org/users/shell.html:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_title('click on points')
line, = ax.plot(np.random.rand(100), '-', picker=5) # 5 points tolerance
def onpick(event):
thisline = event.artist
xdata = thisline.get_xdata()
ydata = thisline.get_ydata()
ind = event.ind
print('onpick points:', *zip(xdata[ind], ydata[ind]))
fig.canvas.mpl_connect('pick_event', onpick)
plt.show()
This plots a straight line plot, as Sohaib was asking
var text = "\"http://example.com\"";
Whatever your text, to wrap it with "
, you need to put them and escape inner ones with \
. Above will result in:
"http://example.com"
I had same problem with Eclipse 3.7.2 (Indigo) and maven 3.0.4.
In my case, the problem was caused by missing maven-resources-plugin-2.4.3.jar
in {user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\2.4.3
folder. (no idea why maven didn't update it)
Solution:
1.) add dependency to pom.xml
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.4.3</version>
</dependency>
2.) run mvn install
from Eclipse or from command line
3.) refresh the project in eclipse (F5)
4.) run Maven > Update Project Configuration...
on project (right click)
JAR file is downloaded to local repository and there are no errors in WS.
You could also use the the basic structure for the PL/pgSQL CASE with anonymous code block procedure block:
DO $$ BEGIN
CASE
WHEN boolean-expression THEN
statements;
WHEN boolean-expression THEN
statements;
...
ELSE
statements;
END CASE;
END $$;

I tried to rebuilt, restart, clean, update Gradle, etc. However, none of them worked for me.
Sometimes, it can be caused by a wrong naming for an XML or resource file.
At least, for me, that problem was solved by changing the name.
In my case I could get the query working by changing "TZR" with "TZD"..
String query = "select * from table1 to_timestamp_tz(origintime,'dd-mm-yyyy hh24:mi:ss TZD') between ? and ?";
The differences are listed in the Javadoc for ListIterator

No, you don't want to store it as a single string in your database like that.
You could use serialize()
but this will make your data harder to search, harder to work with, and wastes space.
You could do some other encoding as well, but it's generally prone to the same problem.
The whole reason you have a DB is so you can accomplish work like this trivially. You don't need a table to store arrays, you need a table that you can represent as an array.
Example:
id | word
1 | Sports
2 | Festivals
3 | Classes
4 | Other
You would simply select the data from the table with SQL, rather than have a table that looks like:
id | word
1 | Sports|Festivals|Classes|Other
That's not how anybody designs a schema in a relational database, it totally defeats the purpose of it.
You can use twiny to create 2 x-axis scales. For Example:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()
a = np.cos(2*np.pi*np.linspace(0, 1, 60.))
ax1.plot(range(60), a)
ax2.plot(range(100), np.ones(100)) # Create a dummy plot
ax2.cla()
plt.show()
Ref: http://matplotlib.sourceforge.net/faq/howto_faq.html#multiple-y-axis-scales

UPDATED AGAIN 2018 (pg10)
little edit to add 2018's results and reinforce recommendations.
My results, after average, in many machines and many tests: all the same
(statistically less tham standard deviation).
Use text
datatype,
avoid old varchar(x)
because sometimes it is not a standard, e.g. in CREATE FUNCTION
clauses varchar(x)
?varchar(y)
.
express limits (with same varchar
performance!) by with CHECK
clause in the CREATE TABLE
e.g. CHECK(char_length(x)<=10)
.
With a negligible loss of performance in INSERT/UPDATE you can also to control ranges and string structure
e.g. CHECK(char_length(x)>5 AND char_length(x)<=20 AND x LIKE 'Hello%')
Had exactly the same problem; I'd brew added [email protected]
(after previously having 5.5).
The brew defaults for 5.6 are innodb_file_per_table=1
whereas in 5.5 they're innodb_file_per_table=0
.
Your existing ibdata1
file (the combined innodb data) will still have references to the tables you're trying to create/drop. Either change innodb_file_per_table
back to 0, or delete the ibdata1 data file (this will lose you all your data, so make sure you mysqldump it first or already have an .sql dump).
The other brew [email protected]
default that bit me was the lack of a port, so networking was defaulting to unix sockets, and the mysql client kept reporting:
ERROR 2013 (HY000): Lost connection to MySQL server at 'sending authentication information', system error: 32
I added <string>--port=3306</string>
to the .plist
array, but you could also specify port=3306
in your my.cnf
Run brew services stop [email protected]
make your changes then brew services start [email protected]
I checked the "Put NetBeans metadata in separate directory" tick and it works fine.
This is in 2. Name and Location after you choose PHP from existing source
matches();
does not buffer, but find()
buffers. find()
searches to the end of the string first, indexes the result, and return the boolean value and corresponding index.
That is why when you have a code like
1:Pattern.compile("[a-z]");
2:Pattern.matcher("0a1b1c3d4");
3:int count = 0;
4:while(matcher.find()){
5:count++: }
At 4: The regex engine using the pattern structure will read through the whole of your code (index to index as specified by the regex[single character]
to find at least one match. If such match is found, it will be indexed then the loop will execute based on the indexed result else if it didn't do ahead calculation like which matches()
; does not. The while statement would never execute since the first character of the matched string is not an alphabet.
For SQL Server 2012, or later, an easier solution is to use FORMAT ()
Documentation.
EG:
SELECT Format(1234567.8, '##,##0')
Results in: 1,234,568

I had a similar question, so I worked up a complete runnable answer below. What I needed to do is pass a class (C) to an object (O) of an unrelated class and have that object (O) emit new objects of class (C) back to me when I asked for them.
The example below shows how this is done. There is a MagicGun class that you load with any subtype of the Projectile class (Pebble, Bullet or NuclearMissle). The interesting is you load it with subtypes of Projectile, but not actual objects of that type. The MagicGun creates the actual object when it's time to shoot.
You've annoyed the target!
You've holed the target!
You've obliterated the target!

String effect = gun.shoot().effectOnTarget();

Did you try
for line in open("masters", "r").readlines(): print line
?
readline()
only reads "a line", on the other hand
readlines()
reads whole lines and gives you a list of all lines.
It marks the string as a verbatim string literal - anything in the string that would normally be interpreted as an escape sequence is ignored.
So "C:\\Users\\Rich"
is the same as @"C:\Users\Rich"
There is one exception: an escape sequence is needed for the double quote. To escape a double quote, you need to put two double quotes in a row. For instance, @""""
evaluates to "
.
Don't ever use the setInterval
or setTimeout
functions for time measuring! They are unreliable, and it is very likely that the JS execution scheduling during a documents parsing and displaying is delayed.
Instead, use the Date
object to create a timestamp when you page began loading, and calculate the difference to the time when the page has been fully loaded:
<doctype html>
<html>
<head>
<script type="text/javascript">
var timerStart = Date.now();
</script>
<!-- do all the stuff you need to do -->
</head>
<body>
<!-- put everything you need in here -->
<script type="text/javascript">
$(document).ready(function() {
console.log("Time until DOMready: ", Date.now()-timerStart);
});
$(window).load(function() {
console.log("Time until everything loaded: ", Date.now()-timerStart);
});
</script>
</body>
</html>
In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:
.ball {
animation: bounce 1s infinite alternate;
-webkit-animation: bounce 1s infinite alternate;
}
@keyframes bounce {
from {
margin-top: 0;
}
to {
margin-top: -15px;
}
}
It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).
BTW gdb
watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.
I went through the exercise to capture low level packet exchange, and found that network connection is only triggered by operations like getInputStream, getOutputStream, getResponseCode, getResponseMessage etc.
Here is the packet exchange captured when I try to write a small program to upload file to Dropbox.
Below is my toy program and annotation
/* Create a connection LOCAL object,
* the openConnection() function DOES NOT initiate
* any packet exchange with the remote server.
*
* The configurations only setup the LOCAL
* connection object properties.
*/
HttpURLConnection connection = (HttpURLConnection) dst.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
...//headers setup
byte[] testContent = {0x32, 0x32};
/**
* This triggers packet exchange with the remote
* server to create a link. But writing/flushing
* to a output stream does not send out any data.
*
* Payload are buffered locally.
*/
try (BufferedOutputStream outputStream = new BufferedOutputStream(connection.getOutputStream())) {
outputStream.write(testContent);
outputStream.flush();
}
/**
* Trigger payload sending to the server.
* Client get ALL responses (including response code,
* message, and content payload)
*/
int responseCode = connection.getResponseCode();
System.out.println(responseCode);
/* Here no further exchange happens with remote server, since
* the input stream content has already been buffered
* in previous step
*/
try (InputStream is = connection.getInputStream()) {
Scanner scanner = new Scanner(is);
StringBuilder stringBuilder = new StringBuilder();
while (scanner.hasNextLine()) {
stringBuilder.append(scanner.nextLine()).append(System.lineSeparator());
}
}
/**
* Trigger the disconnection from the server.
*/
String responsemsg = connection.getResponseMessage();
System.out.println(responsemsg);
connection.disconnect();
Obviously, of the two methods you mention number 1 is more efficient, since it only needs to go through the list once, while with method number 2 the list has to be traversed two times (first to find the elements to remove, and them to remove them).
Actually, removing a list of elements from another list is likely an algorithm that's worse than O(n) so method 2 is even worse.
The iterator method:
List data = ...;
for (Iterator i = data.iterator(); i.hasNext(); ) {
Object element = i.next();
if (!(...)) {
i.remove();
}
}
Maybe this code helps:
var chunk_size = 10;_x000D_
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];_x000D_
var groups = arr.map( function(e,i){ _x000D_
return i%chunk_size===0 ? arr.slice(i,i+chunk_size) : null; _x000D_
}).filter(function(e){ return e; });_x000D_
console.log({arr, groups})

I would use @HostListener decorator within your component:
import { HostListener } from '@angular/core';
@Component({
...
})
export class AppComponent {
@HostListener('document:keypress', ['$event'])
handleKeyboardEvent(event: KeyboardEvent) {
this.key = event.key;
}
}
There are also other options like:
host property within @Component
decorator
Angular recommends using @HostListener
decorator over host property https://angular.io/guide/styleguide#style-06-03
@Component({
...
host: {
'(document:keypress)': 'handleKeyboardEvent($event)'
}
})
export class AppComponent {
handleKeyboardEvent(event: KeyboardEvent) {
console.log(event);
}
}
renderer.listen
import { Component, Renderer2 } from '@angular/core';
@Component({
...
})
export class AppComponent {
globalListenFunc: Function;
constructor(private renderer: Renderer2) {}
ngOnInit() {
this.globalListenFunc = this.renderer.listen('document', 'keypress', e => {
console.log(e);
});
}
ngOnDestroy() {
// remove listener
this.globalListenFunc();
}
}
Observable.fromEvent
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/fromEvent';
import { Subscription } from 'rxjs/Subscription';
@Component({
...
})
export class AppComponent {
subscription: Subscription;
ngOnInit() {
this.subscription = Observable.fromEvent(document, 'keypress').subscribe(e => {
console.log(e);
})
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
If you want to pass non-URL state, then you must not use url
when setting up your state
. I found the answer on a PR and did some monkeying around to better understand.
$stateProvider.state('toState', {
templateUrl:'wokka.html',
controller:'stateController',
params: {
'referer': 'some default',
'param2': 'some default',
'etc': 'some default'
}
});
Then you can navigate to it like so:
$state.go('toState', { 'referer':'jimbob', 'param2':37, 'etc':'bluebell' });
Or:
var result = { referer:'jimbob', param2:37, etc:'bluebell' };
$state.go('toState', result);
And in HTML thusly:
<a ui-sref="toState(thingy)" class="list-group-item" ng-repeat="thingy in thingies">{{ thingy.referer }}</a>
This use case is completely uncovered in the documentation, but I think it's a powerful means on transitioning state without using URLs.
I found that, sometimes, nuget packages will install (what I'm guessing are) .NET Core required components or other items that conflict with the already-installed framework. My solution there was to open the project (.csproj) file and remove those references. For example, System.IO, System.Threading and such, tend to be added when Microsoft.Bcl is included via some recently installed NuGet package. There's no reason for specific versions of those in my projects, so I remove the references and the project builds. Hope that helps.
You can search your project file for "reference" and remove the conflicts. If they're included in System, get rid of them, and the build should work. This may not answer all cases of this issue - I'm making sure you know what worked for me :)
Example of what I commented out:
<!-- <Reference Include="System.Runtime, Version=2.6.9.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL"> -->_x000D_

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.
Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.
Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).
The registry keys of interest (At least in some versions of windows) are:
HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart
will have the value 1
if delayed, 0
if not.HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay
or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay
(on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.Further to RolandTumble's answer to Cody Gray's answer, both fine answers, here is another very simple and flexible way, when you know all of the array contents at coding time - e.g. you just want to build an array that contains 1, 10, 20 and 50. This also uses variant declaration, but doesn't use ReDim. Like in Roland's answer, the enumerated count of the number of array elements need not be specifically known, but is obtainable by using uBound.
sub Demo_array()
Dim MyArray as Variant, MyArray2 as Variant, i as Long
MyArray = Array(1, 10, 20, 50) 'The key - the powerful Array() statement
MyArray2 = Array("Apple", "Pear", "Orange") 'strings work too
For i = 0 to UBound(MyArray)
Debug.Print i, MyArray(i)
Next i
For i = 0 to UBound(MyArray2)
Debug.Print i, MyArray2(i)
Next i
End Sub
I love this more than any of the other ways to create arrays. What's great is that you can add or subtract members of the array right there in the Array statement, and nothing else need be done to code. To add Egg to your 3 element food array, you just type
, "Egg"
in the appropriate place, and you're done. Your food array now has the 4 elements, and nothing had to be modified in the Dim, and ReDim is omitted entirely.
If a 0-based array is not desired - i.e., using MyArray(0) - one solution is just to jam a 0 or "" for that first element.
Note, this might be regarded badly by some coding purists; one fair objection would be that "hard data" should be in Const statements, not code statements in routines. Another beef might be that, if you stick 36 elements into an array, you should set a const to 36, rather than code in ignorance of that. The latter objection is debatable, because it imposes a requirement to maintain the Const with 36 rather than relying on uBound. If you add a 37th element but leave the Const at 36, trouble is possible.
SELECT * FROM Table where codtable not in (Select codtable from Table where fecha is null)
It solved throung second parameter in Model load:
$this->load->model('user','User');
first parameter is the model's filename, and second it defining the name of model to be used in the controller:
function alluser()
{
$this->load->model('User');
$result = $this->User->showusers();
}
Just going to add a simple example to what everyone has explained,
json.load()
json.load
can deserialize a file itself i.e. it accepts a file
object, for example,
# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
print(json.load(content))
will output,
{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}
If I use json.loads
to open a file instead,
# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
print(json.loads(content))
I would get this error:
TypeError: expected string or buffer
json.loads()
json.loads()
deserialize string.
So in order to use json.loads
I will have to pass the content of the file using read()
function, for example,
using content.read()
with json.loads()
return content of the file,
with open("json_data.json", "r") as content:
print(json.loads(content.read()))
Output,
{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}
That's because type of content.read()
is string, i.e. <type 'str'>
If I use json.load()
with content.read()
, I will get error,
with open("json_data.json", "r") as content:
print(json.load(content.read()))
Gives,
AttributeError: 'str' object has no attribute 'read'
So, now you know json.load
deserialze file and json.loads
deserialize a string.
Another example,
sys.stdin
return file
object, so if i do print(json.load(sys.stdin))
, I will get actual json data,
cat json_data.json | ./test.py
{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}
If I want to use json.loads()
, I would do print(json.loads(sys.stdin.read()))
instead.
In the terminal, you are running the node application and it is running your script. That is a very different execution environment than directly running your script in the browser. While the Javascript language is largely the same (both V8 if you're running the Chrome browser), the rest of the execution environment such as libraries available are not the same.
node.js is a server-side Javascript execution environment that combines the V8 Javascript engine with a bunch of server-side libraries. require()
is one such feature that node.js adds to the environment. So, when you run node in the terminal, you are running an environment that contains require()
.
require()
is not a feature that is built into the browser. That is a specific feature of node.js, not of a browser. So, when you try to have the browser run your script, it does not have require()
.
There are ways to run some forms of node.js code in a browser (but not all). For example, you can get browser substitutes for require()
that work similarly (though not identically).
But, you won't be running a web server in your browser as that is not something the browser has the capability to do.
You may be interested in browserify which lets you use node-style modules in a browser using require()
statements.
You have not given us your representation of a polygon. So I am choosing (more like suggesting) one for you :)
Represent each polygon as one big convex polygon, and a list of smaller convex polygons which need to be 'subtracted' from that big convex polygon.
Now given two polygons in that representation, you can compute the intersection as:
Compute intersection of the big convex polygons to form the big polygon of the intersection. Then 'subtract' the intersections of all the smaller ones of both to get a list of subracted polygons.
You get a new polygon following the same representation.
Since convex polygon intersection is easy, this intersection finding should be easy too.
This seems like it should work, but I haven't given it more deeper thought as regards to correctness/time/space complexity.
Use two dimensional array instead. For instance, int values[][] = new int[2][5];
Arrays are faster, when you are not manipulating much.
This worked for me,
IF OBJECT_ID('tempdb.dbo.#tempTable') IS NOT NULL
DROP TABLE #tempTable;
Here tempdb.dbo(dbo is nothing but your schema) is having more importance.
You can't target each word in CSS. However, with a bit of jQuery you probably could.
With jQuery you can wrap each word in a <span>
and then CSS set span to display:block
which would put it on its own line.
In theory of course :P
Simple is that:
IF OBJECT_ID(dbo.TableName, 'U') IS NOT NULL
DROP TABLE dbo.TableName
where dbo.TableName
is your desired table and 'U' is type
of your table
.
Or you can use an alternative:
https://github.com/kint-php/kint
It works with zero set up and has much more features than Xdebug's var_dump anyway. To bypass the nested limit on the fly with Kint, just use
+d( $variable ); // append `+` to the dump call
Coming from SQL Server as well, and this really bugged me. For those using Toad Data Point or Toad for Oracle, it's extremely simple. Just putting a colon in front of your variable name will prompt Toad to open a dialog where you enter the value on execute.

Each deployed webapp has a context.xml
file that lives in
$CATALINA_BASE/conf/[enginename]/[hostname]
(conf/Catalina/localhost by default)
and has the same name as the webapp (manager.xml
in this case). If no file is present, default values are used.
So, you need to create a file conf/Catalina/localhost/manager.xml
and specify the rule you want to allow remote access. For example, the following content of manager.xml
will allow access from all machines:
<Context privileged="true" antiResourceLocking="false"
docBase="${catalina.home}/webapps/manager">
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^YOUR.IP.ADDRESS.HERE$" />
</Context>
Note that the allow attribute of the Valve
element is a regular expression that matches the IP address of the connecting host. So substitute your IP address for YOUR.IP.ADDRESS.HERE (or some other useful expression).
Other Valve
classes cater for other rules (e.g. RemoteHostValve
for matching host names). Earlier versions of Tomcat use a valve class org.apache.catalina.valves.RemoteIpValve for IP address matching.
Once the changes above have been made, you should be presented with an authentication dialog when accessing the manager URL. If you enter the details you have supplied in tomcat-users.xml
you should have access to the Manager.
I liked Jed's solution but the issue with that was every time I built my project in debug mode, it would deploy my database project and removed the user again. so I added this MySQL script to the Post-Deployment script. it practically does what Jed said but creates the user every time I deploy.

Have you tried using JsonSlurper?
Example usage:
def slurper = new JsonSlurper()
def result = slurper.parseText('{"person":{"name":"Guillaume","age":33,"pets":["dog","cat"]}}')
assert result.person.name == "Guillaume"
assert result.person.age == 33
assert result.person.pets.size() == 2
assert result.person.pets[0] == "dog"
assert result.person.pets[1] == "cat"
I assume the question is already answered. If above solution doesn't help in solving the issue then can use below to solve the issue.
The issue occurs if sometimes your maven user settings is not reflecting correct settings.xml file.
To update the settings file go to Windows > Preferences > Maven > User Settings and update the settings.xml to it correct location.
Once this is doen re-build the project, these should solve the issue. Thanks.

Building upon the answer from booij boy, check if you checked the "windows authentication" feature in Control Panel -> Programs -> Turn windows features on or of -> Internet Information Services -> World Wide Web Services -> Security
Also, there seems to be a big difference when using firefox or internet explorer. After enabeling the "windows authentication" it works for me but only in IE.
That means that the definition of your function is not present in your program. You forgot to add that one.cpp
to your program.
What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp
to the project.
In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp
is missing.
Simplest way is to use dimensions in % or em. Just change the base font size everything will change.

Just for the record if somebody needs a way to handle signals on Windows. I had a requirement to handle from prog A calling prog B through os/exec but prog B never was able to terminate gracefully because sending signals through ex. cmd.Process.Signal(syscall.SIGTERM) or other signals are not supported on Windows. The way I handled is by creating a temp file as a signal ex. .signal.term through prog A and prog B needs to check if that file exists on interval base, if file exists it will exit the program and handle a cleanup if needed, I'm sure there are other ways but this did the job.
You get this message in the logs, because you do something that is not allowed in the current state of your MediaPlayer instance.
Therefore you should always register an error handler to catch those things (as @tidbeck suggested).
At first, I advice you to take a look at the documentation for the MediaPlayer
class and get an understanding of what that with states means. See: http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram
Your mistake here could well be one of the common ones, the others wrote here, but in general, I would take a look at the documentation of what methods are valid to call in what state: http://developer.android.com/reference/android/media/MediaPlayer.html#Valid_and_Invalid_States
In my example it was the method mediaPlayer.CurrentPosition
, that I called while the media player was in a state, where it was not allowed to call this property.

but what i am doing is purely synchronous
You could use HttpClient
for synchronous requests just fine:
using (var client = new HttpClient())
{
var response = client.GetAsync("http://google.com").Result;
if (response.IsSuccessStatusCode)
{
var responseContent = response.Content;
// by calling .Result you are synchronously reading the result
string responseString = responseContent.ReadAsStringAsync().Result;
Console.WriteLine(responseString);
}
}
As far as why you should use HttpClient
over WebRequest
is concerned, well, HttpClient
is the new kid on the block and could contain improvements over the old client.
This is just like passing the error to the stdout or the terminal.
That is, cmd
is not a command:
$cmd 2>filename
cat filename
command not found
The error is sent to the file like this:
2>&1
Standard error is sent to the terminal.
I stumbled upon this problem again. But this time it occurred for a different reason. I had copied files into the repo to overwrite the previous versions. Now I can see the files are modified but diff doesn't return the diffs.
For example, I have a mainpage.xaml file.
In File Explorer I pasted a new mainpage.xaml file over the one in my current repo.
I did the work on another machine and just pasted the file here.
The file shows modified, but when I run git diff, it will not show the changes. It's probably because the fileinfo on the file has changed and git knows that it isn't really the same file. Interesting.
You can see that when I run diff on the file it shows nothing, just returns the prompt.
I'm a MacOS user.
I solved it by uninstalling Android Studio and reinstalling it again.
If you want to try this link helped me a lot.
I have to pass two parameters like:
/Controller/Action/Param1Value/Param2Value
This way:
@Html.ActionLink(
linkText,
actionName,
controllerName,
routeValues: new {
Param1Name= Param1Value,
Param2Name = Param2Value
},
htmlAttributes: null
)
will generate this url
/Controller/Action/Param1Value?Param2Name=Param2Value
I used a workaround method by merging parameter two in parameter one and I get what I wanted:
@Html.ActionLink(
linkText,
actionName,
controllerName,
routeValues: new {
Param1Name= "Param1Value / Param2Value" ,
},
htmlAttributes: null
)
And I get :
/Controller/Action/Param1Value/Param2Value
You need to
#include <string>
<iostream>
declares cout
, cin
, not string
.
in swift 5 we do like, Use typealias for the completion. Typlealias nothing just use to clean the code.
typealias response = (Bool,Any?)->()
static func postCall(_ url : String, param : [String : Any],completion : @escaping response){
Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: [:]).responseJSON { (response) in
switch response.result {
case .success(let JSON):
print("\n\n Success value and JSON: \(JSON)")
case .failure(let error):
print("\n\n Request failed with error: \(error)")
}
}
}
CASE
isn't used for flow control... for this, you would need to use IF
...
But, there's a set-based solution to this problem instead of the procedural approach:
UPDATE tblEmployee
SET
InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID
Note that the ELSE
will preserves the original value if the @NewStatus
condition isn't met.
I'm not sure I agree with inheritance from ValueError
-- my interpretation of the documentation is that ValueError
is only supposed to be raised by builtins... inheriting from it or raising it yourself seems incorrect.
Raised when a built-in operation or function receives an argument that has the right type but an inappropriate value, and the situation is not described by a more precise exception such as IndexError.
<?php
if (isset($_POST['str'])){
function printme($str){
echo $str;
}
printme("{$_POST['str']}");
}
?>
<form action="<?php $_PHP_SELF ?>" method="POST">
<input type="text" name="str" /> <input type="submit" value="Submit"/>
</form>
What you have seems to be a string
incorrectly decoded from another encoding, likely code page 1252, which is US Windows default. Here's how to reverse, assuming no other loss. One loss not immediately apparent is the non-breaking space
(U+00A0) at the end of your string that is not displayed. Of course it would be better to read the data source correctly in the first place, but perhaps the data source was stored incorrectly to begin with.
using System;
using System.Text;
class Program
{
static void Main(string[] args)
{
string junk = "déjÃ\xa0"; // Bad Unicode string
// Turn string back to bytes using the original, incorrect encoding.
byte[] bytes = Encoding.GetEncoding(1252).GetBytes(junk);
// Use the correct encoding this time to convert back to a string.
string good = Encoding.UTF8.GetString(bytes);
Console.WriteLine(good);
}
}
Result:
déjà
You should definitely have a look at this answer of mine:

Tabula/TabulaPDF is currently the best table extraction tool that is available for PDF scraping.
Coming from someone who has tried a number of "C# IDEs" on the Mac, your best bet is to install a virtual desktop with Windows and Visual Studio. It really is the best development IDE out there for .NET, nothing even comes close.
On a related note: I hate XCode.
Update: Use Xamarin Studio. It's solid.
It may be hackish to some, but I learned this way from how Cakephp does some functions and have adapted it because I like the flexibility it creates
The idea is you have different type of arguments, arrays, objects etc, then you detect what you were passed and go from there
function($arg1, $lastname) {
if(is_array($arg1)){
$lastname = $arg1['lastname'];
$firstname = $arg1['firstname'];
} else {
$firstname = $arg1;
}
...
}
I was trying to solve the same problem, but found an interesting advice by Basarat Ali Syed, of TypeScript Deep Dive fame, that we should avoid the generic export default
declaration for a class, and instead append the export
tag to the class declaration. The imported class should be instead listed in the import
command of the module.
That is: instead of
class Foo {
// ...
}
export default Foo;
and the simple import Foo from './foo';
in the module that will import, one should use
export class Foo {
// ...
}
and import {Foo} from './foo'
in the importer.
The reason for that is difficulties in the refactoring of classes, and the added work for exportation. The original post by Basarat is in export default
can lead to problems
Login to virtual machine use below command to check ip address. (anyone will work)
If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1
If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine
You should place Scanner input = new Scanner (System.in);
into the main method rather than creating the input object outside.

You can do this using Input.setSelectionRange
, part of the Range API for interacting with text selections and the text cursor:
var searchInput = $('#Search');
// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;
searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);
Demo: Fiddle
By default Spring uses org.springframework.boot.orm.jpa.SpringNamingStrategy
to generate table names. This is a very thin extension of org.hibernate.cfg.ImprovedNamingStrategy
. The tableName
method in that class is passed a source String
value but it is unaware if it comes from a @Column.name
attribute or if it has been implicitly generated from the field name.
The ImprovedNamingStrategy
will convert CamelCase
to SNAKE_CASE
where as the EJB3NamingStrategy
just uses the table name unchanged.
If you don't want to change the naming strategy you could always just specify your column name in lowercase:
@Column(name="testname")
List<Customer> list = ...;
Customer john = list.SingleOrDefault(customer => customer.Firstname == "John");
john will be null if no customer exists with a first name of "John".
Note that, image slicing is not creating a copy of the cropped image
but creating a pointer
to the roi
. If you are loading so many images, cropping the relevant parts of the images with slicing, then appending into a list, this might be a huge memory waste.
Suppose you load N images each is >1MP
and you need only 100x100
region from the upper left corner.
Slicing
:
X = []
for i in range(N):
im = imread('image_i')
X.append(im[0:100,0:100]) # This will keep all N images in the memory.
# Because they are still used.
Alternatively, you can copy the relevant part by .copy()
, so garbage collector will remove im
.
X = []
for i in range(N):
im = imread('image_i')
X.append(im[0:100,0:100].copy()) # This will keep only the crops in the memory.
# im's will be deleted by gc.
After finding out this, I realized one of the comments by user1270710 mentioned that but it took me quite some time to find out (i.e., debugging etc). So, I think it worths mentioning.
To simplify Amiram Korach's solution:
dtList.RemoveAll(s => string.IsNullOrWhiteSpace(s))
No need to use Distinct() or ToList()
Before creating a new branch always the best practice is to have the latest of repo in your local machine. Follow these steps for error free branch creation.
1. $ git branch (check which branches exist and which one is currently active (prefixed with *). This helps you avoid creating duplicate/confusing branch name)
2. $ git branch <new_branch> (creates new branch)
3. $ git checkout new_branch
4. $ git add . (After making changes in the current branch)
5. $ git commit -m "type commit msg here"
6. $ git checkout master (switch to master branch so that merging with new_branch can be done)
7. $ git merge new_branch (starts merging)
8. $ git push origin master (push to the remote server)
I referred this blog and I found it to be a cleaner approach.
I like Clay Eclipse plugin. I've only used it with MySQL, but it claims Firebird support.
C does not and never has had a native string type. By convention, the language uses arrays of char
terminated with a null char, i.e., with '\0'
. Functions and macros in the language's standard libraries provide support for the null-terminated character arrays, e.g., strlen iterates over an array of char
until it encounters a '\0'
character and strcpy copies from the source string until it encounters a '\0'
.
The use of null-terminated strings in C reflects the fact that C was intended to be only a little more high-level than assembly language. Zero-terminated strings were already directly supported at that time in assembly language for the PDP-10 and PDP-11.
It is worth noting that this property of C strings leads to quite a few nasty buffer overrun bugs, including serious security flaws. For example, if you forget to null-terminate a character string passed as the source argument to strcpy
, the function will keep copying sequential bytes from whatever happens to be in memory past the end of the source string until it happens to encounter a 0
, potentially overwriting whatever valuable information follows the destination string's location in memory.
In your code example, the string literal "Hello, world!" will be compiled into a 14-byte long array of char
. The first 13 bytes will hold the letters, comma, space, and exclamation mark and the final byte will hold the null-terminator character '\0'
, automatically added for you by the compiler. If you were to access the array's last element, you would find it equal to 0
. E.g.:
const char foo[] = "Hello, world!";
assert(foo[12] == '!');
assert(foo[13] == '\0');
However, in your example, message
is only 10 bytes long. strcpy
is going to write all 14 bytes, including the null-terminator, into memory starting at the address of message
. The first 10 bytes will be written into the memory allocated on the stack for message
and the remaining four bytes will simply be written on to the end of the stack. The consequence of writing those four extra bytes onto the stack is hard to predict in this case (in this simple example, it might not hurt a thing), but in real-world code it usually leads to corrupted data or memory access violation errors.
Use this script tossh within script, First argument is the hostname and second will be the password.

System.out.println

Use DefinePlugin.
The DefinePlugin allows you to create global constants which can be configured at compile time.
new webpack.DefinePlugin(definitions)
plugins: [
new webpack.DefinePlugin({
PRODUCTION: JSON.stringify(true)
})
//...
]
console.log(`Environment is in production: ${PRODUCTION}`);
It prints the byte
in Hexadecimal format.

I know this is an old question I thought I might just add my 2 cents.
If you have a List<Something>[]
you can join them using Aggregate
public List<TType> Concat<TType>(params List<TType>[] lists)
{
var result = lists.Aggregate(new List<TType>(), (x, y) => x.Concat(y).ToList());
return result;
}
Hope this helps.
You can also set the options --log-fd if you just want to read your logs with a less. For example :
valgrind --log-fd=1 ls | less
jww is right — you're referencing the wrong intermediate certificate.
As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt
I noticed that at least two proposed solutions don't handle overlapping search hits. I didn't check the one marked with the green checkmark. Here is one that handles overlapping search hits:
public static List<int> GetPositions(this string source, string searchString)
{
List<int> ret = new List<int>();
int len = searchString.Length;
int start = -1;
while (true)
{
start = source.IndexOf(searchString, start +1);
if (start == -1)
{
break;
}
else
{
ret.Add(start);
}
}
return ret;
}
First of all we will need serializeObject();
$.fn.serializeObject = function () {
var o = {};
var a = this.serializeArray();
$.each(a, function () {
if (o[this.name]) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
then you make a basic post and get response
$.post("/Education/StudentSave", $("#frmNewStudent").serializeObject(), function (data) {
if(data){
//do true
}
else
{
//do false
}
});
You might be using C:/[your-php-directory]/php.exe in Handler mapping of IIS just change it C:/[your-php-directory]/php-cgi.exe.
For those of you who just want to allow max. 2 <br>
in a row, you can use this:
let text = text.replace(/(\r?\n){2,}/g, '<br><br>');
text = text.replace(/(\r?\n)/g, '<br>');
First line: Search for \n
OR \r\n
where at least 2 of them are in a row, e.g. \n\n\n\n
. Then replace it with 2 br
Second line: Search for all single \r\n
or \n
and replace them with <br>
Scott Meyers tells you to prefer prefix except on those occasions where logic would dictate that postfix is appropriate.
"More Effective C++" item #6 - that's sufficient authority for me.
For those who don't own the book, here are the pertinent quotes. From page 32:
From your days as a C programmer, you may recall that the prefix form of the increment operator is sometimes called "increment and fetch", while the postfix form is often known as "fetch and increment." The two phrases are important to remember, because they all but act as formal specifications...
And on page 34:
If you're the kind who worries about efficiency, you probably broke into a sweat when you first saw the postfix increment function. That function has to create a temporary object for its return value and the implementation above also creates an explicit temporary object that has to be constructed and destructed. The prefix increment function has no such temporaries...
Try to use deep Equal. It will compare nested arrays as well as nested Json.
expect({ foo: 'bar' }).to.deep.equal({ foo: 'bar' });

You can use the CONVERT

Why you need to implement shuffle when it already exists? Stay on the shoulders of giants.
import random
d1 = {0:'zero', 1:'one', 2:'two', 3:'three', 4:'four',
5:'five', 6:'six', 7:'seven', 8:'eight', 9:'nine'}
keys = list(d1)
random.shuffle(keys)
d2 = {}
for key in keys: d2[key] = d1[key]
print(d1)
print(d2)
If we have 3 parameters (t0, a0, a1)
for Relu, that is we want to implement
if x > t0:
x = x * a1
else:
x = x * a0
We can use the following code:
X = X * (X > t0) * a1 + X * (X < t0) * a0
X
there is a matrix.
If you want to print decimal variables:
wchar_t text_buffer[20] = { 0 }; //temporary buffer
swprintf(text_buffer, _countof(text_buffer), L"%d", your.variable); // convert
OutputDebugString(text_buffer); // print
Try this:
$(".datepicker").on("dp.change", function(e) {
alert('hey');

A UUID created by CFUUIDCreate
is unique if a user uninstalls and re-installs the app: you will get a new one each time.
But you might want it to be not unique, i. e. it should stay the same when the user uninstalls and re-installs the app. This requires a bit of effort, since the most reliable per-device-identifier seems to be the MAC address. You could query the MAC and use that as UUID.
Edit: One needs to always query the MAC of the same interface, of course. I guess the best bet is with en0
. The MAC is always present, even if the interface has no IP/is down.
Edit 2: As was pointed out by others, the preferred solution since iOS 6 is -[UIDevice identifierForVendor]. In most cases, you should be able use it as a drop-in replacement to the old -[UIDevice uniqueIdentifier]
(but a UUID that is created when the app starts for the first time is what Apple seems to want you to use).
Edit 3: So this major point doesn't get lost in the comment noise: do not use the MAC as UUID, create a hash using the MAC. That hash will always create the same result every time, even across reinstalls and apps (if the hashing is done in the same way). Anyways, nowadays (2013) this isn't necessary any more except if you need a "stable" device identifier on iOS < 6.0.
Edit 4: In iOS 7, Apple now always returns a fixed value when querying the MAC to specifically thwart the MAC as base for an ID scheme. So you now really should use -[UIDevice identifierForVendor] or create a per-install UUID.
First Strong/Weak Reference types are introduced in ARC. In Non ARC assign/retain are being used. A strong reference means that you want to "own" the object you are referencing with this property/variable. The compiler will take care that any object that you assign to this property will not be destroyed as long as you points to it with a strong reference. Only once you set the property to nil, the object get destroyed.
A weak reference means you signify that you don't want to have control over the object's lifetime or don't want to "own" object. The object you are referencing weakly only lives on because at least one other object holds a strong reference to it. Once that is no longer the case, the object gets destroyed and your weak property will automatically get set to nil. The most frequent use cases of weak references in iOS are for IBOutlets, Delegates etc.

I have worked on some servers where sort don't support '-u' option. there we have to use
sort xyz | uniq
You can use StringBuffer
StringBuffer text = new StringBuffer("Hello World");
text.replace( StartIndex ,EndIndex ,String);
followers_df.reset_index()
followers_df.reindex(index=range(0,20))
Here you go:
^[^<>]*$
This will test for string that has no <
and no >
If you want to test for a string that may have <
and >
, but must also have something other you should use just
[^<>] (or ^.*[^<>].*$)
Where [<>]
means any of <
or >
and [^<>]
means any that is not of <
or >
.
And of course the mandatory link.

Normally Python throws NameError
if the variable is not defined:
>>> d[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined
However, you've managed to stumble upon a name that already exists in Python.
Because dict
is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.
The type of dict
is a type
. All types are objects in Python. Thus you are actually trying to index into the type
object. This is why the error message says that the "'type' object is not subscriptable."
>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable
Note that you can blindly assign to the dict
name, but you really don't want to do that. It's just going to cause you problems later.
>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'
The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:
d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))
You can also create a database named 'mydatabasename' and then try restoring it again.
Create a new database using MySQL CLI:
mysql -u[username] -p[password]
CREATE DATABASE mydatabasename;
Then try to restore your database:
mysql -u[username] -p[password] mydatabase<mydatabase.sql;
what about the retrying library on pypi? I have been using it for a while and it does exactly what I want and more (retry on error, retry when None, retry with timeout). Below is example from their website:
import random
from retrying import retry
@retry
def do_something_unreliable():
if random.randint(0, 10) > 1:
raise IOError("Broken sauce, everything is hosed!!!111one")
else:
return "Awesome sauce!"
print do_something_unreliable()
In addition to the several programatic approaches discussed, another option is to redirect standard output from the shell. Here are several Unix and DOS examples.
Based on @Rick answer which was really helpful.
You have to scape the string data
if you want to share it this way:
$('a.download').attr('href', 'data:application/csv;charset=utf-8,'+ encodeURI(data));
` Sorry I can not comment on @Rick's answer due to my current low reputation in StackOverflow.
An edit suggestion was shared and rejected.
One way is to use ANSI escape sequences:
import sys
import time
for i in range(10):
print("Loading" + "." * i)
sys.stdout.write("\033[F") # Cursor up one line
time.sleep(1)
Also sometimes useful (for example if you print something shorter than before):
sys.stdout.write("\033[K") # Clear to the end of line
You can get the introduction of the article in Wikipedia by querying pages such as https://en.wikipedia.org/w/api.php?format=json&action=query&prop=extracts&exintro=&explaintext=&titles=java. You just need to parse the json file and the result is plain text which has been cleaned including removing links and references.
If any of the above method is not working and you code is perfect then try hard refreshing by pressing Ctrl + F5. It will clear all the chaces and then reload file. It worked for me.
\
is an escape character in Python. \t
gets interpreted as a tab. If you need \
character in a string, you have to use \\
.
Your code should be:
test_file=open('c:\\Python27\\test.txt','r')
The reason the code will not work without void
is because the System.out.println(String string)
method returns nothing and just prints the supplied arguments to the standard out terminal, which is the computer monitor in most cases. When a method returns "nothing" you have to specify that by putting the void
keyword in its signature.
You can see the documentation of the System.out.println here:
http://download.oracle.com/javase/6/docs/api/java/io/PrintStream.html#println%28java.lang.String%29
To press the issue further, println is a classic example of a method which is performing computation as a "side effect."

just posting in case anyone else has the same error...
I was using 'await' outside of an 'async' function and for whatever reason that results in a 'missing ) after argument list' error.
The solution was to make the function asynchronous
function functionName(args) {}
becomes
async function functionName(args) {}
Try this:
$Date = $row['valdate']->format('d/m/Y'); // the result will 01/12/2015
NOTE: $row['valdate']
its a value date in the database
Mostly, I prefer to use this syntax :
if ($('#MyId')!= null) {
// dostuff
}
Even if this code is not commented, the functionality is obvious.
You can use the more
command. For example:
more filename.txt
Take a look at GNU utilities for Win32 or download it:
Adding another answer that uses switch
... There are more comprehensive examples out there, but this will give you the idea.
In example, t
becomes the specified data type within each case
scope. Note, you have to provide a case
for only one type at a type, otherwise t
remains an interface
.
package main
import "fmt"
func main() {
var val interface{} // your starting value
val = 4
var i int // your final value
switch t := val.(type) {
case int:
fmt.Printf("%d == %T\n", t, t)
i = t
case int8:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case int16:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case int32:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case int64:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case bool:
fmt.Printf("%t == %T\n", t, t)
// // not covertible unless...
// if t {
// i = 1
// } else {
// i = 0
// }
case float32:
fmt.Printf("%g == %T\n", t, t)
i = int(t) // standardizes across systems
case float64:
fmt.Printf("%f == %T\n", t, t)
i = int(t) // standardizes across systems
case uint8:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case uint16:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case uint32:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case uint64:
fmt.Printf("%d == %T\n", t, t)
i = int(t) // standardizes across systems
case string:
fmt.Printf("%s == %T\n", t, t)
// gets a little messy...
default:
// what is it then?
fmt.Printf("%v == %T\n", t, t)
}
fmt.Printf("i == %d\n", i)
}
Yes. Have a look at Wikipedia and Cloanto Implementation of INI File Format (see bottom of page).
Alternatively, you can use requests.Session
and observe cookies
before and after a request:
>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())
{}
>>> response = session.get('http://google.com')
>>> print(session.cookies.get_dict())
{'PREF': 'ID=5514c728c9215a9a:FF=0:TM=1406958091:LM=1406958091:S=KfAG0U9jYhrB0XNf', 'NID': '67=TVMYiq2wLMNvJi5SiaONeIQVNqxSc2RAwVrCnuYgTQYAHIZAGESHHPL0xsyM9EMpluLDQgaj3db_V37NjvshV-eoQdA8u43M8UwHMqZdL-S2gjho8j0-Fe1XuH5wYr9v'}

What is the difference between Git and GitHub?
Linus Torvalds would kill you for this. Git is the name of the version manager program he wrote. GitHub is a website on which there are source code repositories manageable by Git. Thus, GitHub is completely unrelated to the original Git tool.
Is git saving every repository locally (in the user's machine) and in GitHub?
If you commit changes, it stores locally. Then, if you push the commits, it also sotres them remotely.
Can you use Git without GitHub? If yes, what would be the benefit for using GitHub?
You can, but I'm sure you don't want to manually set up a git server for yourself. Benefits of GitHub? Well, easy to use, lot of people know it so others may find your code and follow/fork it to make improvements as well.
How does Git compare to a backup system such as Time Machine?
Git is specifically designed and optimized for source code.
Is this a manual process, in other words if you don't commit you wont have a new version of the changes made?
Exactly.
If are not collaborating and you are already using a backup system why would you use Git?
See #4.
Please use
{!! $test !!}
Only in case of HTML while if you want to render data, sting etc. use
{{ $test }}
This is because when your blade file is compiled
{{ $test }}
is converted to <?php echo e($test) ?>
while
{!! $test !!}
is converted to <?php echo $test ?>
try adding this in AppDelegate applicationWillEnterForeground.

If you're having issues compiling the binary extension, or on a platform where you cant, you can try using the pure python PyMySQL
bindings.
Simply pip install pymysql
and switch your SQLAlchemy URI to start like this:
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://.....'
There are some other drivers you could also try.
With a FrameLayout you can place a text on top of an image view, the frame layout holding both an imageView and a textView.
If that's not enough and you want something more fancy like 'drawing' text, you need to draw text on a canvas - a sample is here: How to draw RTL text (Arabic) onto a Bitmap and have it ordered properly?
Try looking at decode string encoded in utf-8 format in android but it doesn't look like your string is encoded with anything particular. What do you think the output should be?
I looked at every solution (and tried a few) from this page but I was not convinced that we have to kind of implement a hack-ish way to achieve the data transfer between route.
Another problem with simple history.state
is that if you are passing an instance of a particular class in the state
object, it will not be the instance while receiving it. But it will be a plain simple JavaScript object.
So in my Angular v10 (Ionic v5) application, I did this-
this.router.navigateByUrl('/authenticate/username', {
state: {user: new User(), foo: 'bar'}
});
And in the navigating component ('/authenticate/username'
), in ngOnInit()
method, I printed the data with this.router.getCurrentNavigation().extras.state
-
ngOnInit() {
console.log('>>authenticate-username:41:',
this.router.getCurrentNavigation().extras.state);
}
And I got the desired data which was passed-
Very interesting question. I think it's mainly a semantic meaning, and may also be due to historical reasons.
Although in current Android Activity and Service implementations, getApplication()
and getApplicationContext()
return the same object, there is no guarantee that this will always be the case (for example, in a specific vendor implementation).
So if you want the Application class you registered in the Manifest, you should never call getApplicationContext()
and cast it to your application, because it may not be the application instance (which you obviously experienced with the test framework).
Why does getApplicationContext()
exist in the first place ?
getApplication()
is only available in the Activity class and the Service class, whereas getApplicationContext()
is declared in the Context class.
That actually means one thing : when writing code in a broadcast receiver, which is not a context but is given a context in its onReceive method, you can only call getApplicationContext()
. Which also means that you are not guaranteed to have access to your application in a BroadcastReceiver.
When looking at the Android code, you see that when attached, an activity receives a base context and an application, and those are different parameters. getApplicationContext()
delegates it's call to baseContext.getApplicationContext()
.
One more thing : the documentation says that it most cases, you shouldn't need to subclass Application:
There is normally no need to subclass
Application
. In most situation, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), the function to retrieve it can be given aContext
which internally usesContext.getApplicationContext()
when first constructing the singleton.
I know this is not an exact and precise answer, but still, does that answer your question?
The JSON sample you provided is not valid. Check it online with this JSON Validator http://jsonlint.com/. You need to remove the extra comma on line 59.

This is for es2015

but this a great way to do it (with TypeScript
).
let values: any[] = [];
const distinct = (value: any, index: any, self: any) => {
return self.indexOf(value) === index;
};
values = values.filter(distinct);
The top-rated answer with NVL is totally valid. If you have any interest in making your SQL code more portable, you might want to use CASE, which is supported with the same syntax in both Oracle and SQL Server:
select
type,craft,
SUM(
case when regular is null
then 0
else regular
end
+
case when overtime is null
then 0
else overtime
end
) as total_hours
from
hours_t
group by
type
,craft
order by
type
,craft
Here is an elegant way to do similar thing. But why do partly JSON unmarshal? That doesn't make sense.

}
}`
type SendMsg struct {
User string `json:"user"`
Msg string `json:"msg"`
}
type Chat struct {
Say string `json:"say"`
SendMsg *SendMsg `json:"sendMsg"`
}
func main() {
/** Clean way to solve Json Decoding in Go */
/** Excellent solution */
var chat Chat
r := bytes.NewReader([]byte(messeging))
chatErr := json.NewDecoder(r).Decode(&chat)
errHandler(chatErr)
fmt.Println(chat.Say)
fmt.Println(chat.SendMsg.User)
fmt.Println(chat.SendMsg.Msg)
}
func errHandler(err error) {
if err != nil {
fmt.Println(err)
return

If you compare output for x+x , x*2 and x<<1 syntax on a gcc compiler, then you would get the same result in x86 assembly : https://godbolt.org/z/JLpp0j
push rbp
mov rbp, rsp
mov DWORD PTR [rbp-4], edi
mov eax, DWORD PTR [rbp-4]
add eax, eax
pop rbp

So you can consider gcc as smart enought to determine his own best solution independently from what you typed.
I've used Flexcel in the past and it was great. But this was more for programmatically creating and updating excel worksheets.
The simplest way might be:
var func='myDynamicFunction_'+myHandler;
var arg1 = 100, arg2 = 'abc';
window[func].apply(null,[arg1, arg2]);
Assuming, that target function is already attached to a "window" object.
You are trying to call do_something before you declare it. You need to add a function prototype before your printf line:
char* do_something(char*, const char*);
Or you need to move the function definition above the printf line. You can't use a function before it is declared.
SELECT * FROM employees e1, employees e2
WHERE e1.phoneNumber = e2.phoneNumber
AND e1.id != e2.id;
Update : for better performance and faster query its good to add e1
before *
SELECT e1.* FROM employees e1, employees e2
WHERE e1.phoneNumber = e2.phoneNumber
AND e1.id != e2.id;

instanceof is probably going to be more costly than a simple equals in most real world implementations (that is, the ones where instanceof is really needed, and you can't just solve it by overriding a common method, like every beginner textbook as well as Demian above suggest).
Why is that? Because what is probably going to happen is that you have several interfaces, that provide some functionality (let's say, interfaces x, y and z), and some objects to manipulate that may (or not) implement one of those interfaces... but not directly. Say, for instance, I have:
w extends x
A implements w
B extends A
C extends B, implements y
D extends C, implements z
Suppose I am processing an instance of D, the object d. Computing (d instanceof x) requires to take d.getClass(), loop through the interfaces it implements to know whether one is == to x, and if not do so again recursively for all of their ancestors... In our case, if you do a breadth first exploration of that tree, yields at least 8 comparisons, supposing y and z don't extend anything...
The complexity of a real-world derivation tree is likely to be higher. In some cases, the JIT can optimize most of it away, if it is able to resolve in advance d as being, in all possible cases, an instance of something that extends x. Realistically, however, you are going to go through that tree traversal most of the time.
If that becomes an issue, I would suggest using a handler map instead, linking the concrete class of the object to a closure that does the handling. It removes the tree traversal phase in favor of a direct mapping. However, beware that if you have set a handler for C.class, my object d above will not be recognized.
here are my 2 cents, I hope they help...

Before MySQL 5.6 Full-Text Search is supported only with MyISAM Engine.
Therefore either change the engine for your table to MyISAM
CREATE TABLE gamemech_chat (
id bigint(20) unsigned NOT NULL auto_increment,
from_userid varchar(50) NOT NULL default '0',
to_userid varchar(50) NOT NULL default '0',
text text NOT NULL,
systemtext text NOT NULL,
timestamp datetime NOT NULL default '0000-00-00 00:00:00',
chatroom bigint(20) NOT NULL default '0',
PRIMARY KEY (id),
KEY from_userid (from_userid),
FULLTEXT KEY from_userid_2 (from_userid),
KEY chatroom (chatroom),
KEY timestamp (timestamp)
) ENGINE=MyISAM;
Here is SQLFiddle demo
or upgrade to 5.6 and use InnoDB Full-Text Search.
Update a row or column of a table
$update = "UPDATE daily_patients SET queue_status = 'pending' WHERE doctor_id = $room_no and serial_number= $serial_num";
if ($con->query($update) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $con->error;
}
I had this pop up recently where a function was being called prior to its definition in the same file, and it didnt have the returned value assigned to a variable. Adding a var for the return value to be assigned to made the error go away.
for (let key in data) {
let value = data[key];
for (i = 0; i < value.length; i++) {
console.log(value[i].msgFrom);
console.log(value[i].msgBody);
}
}
8388608 bytes is 8M, the default limit in PHP. Update your post_max_size
in php.ini to a larger value.
upload_max_filesize
sets the max file size that a user can upload while
post_max_size
sets the maximum amount of data that can be sent via a POST in a form.
So you can set upload_max_filesize
to 1 meg, which will mean that the biggest single file a user can upload is 1 megabyte, but they could upload 5 of them at once if the post_max_size
was set to 5.
You can call the single method with a predicate:
var portCode = Database.DischargePorts
.Single(p => p.PortName.Contains("BALTIMORE"))
.PortCode;
You write this function in sql server after that problem will be solved.

Well, there are important differences between how OneHot Encoding and Label Encoding work :
int
. In this case, the 1st class found will be coded as 1
, the 2nd as 2
, ...
But this encoding creates an issue.Let's take the example of a variable Animal = ["Dog", "Cat", "Turtle"]
.
If you use Label Encoder on it, Animal
will be [1, 2, 3]
. If you parse it to your machine learning model, it will interpret Dog
is closer than Cat
, and farther than Turtle
(because distance between 1
and 2
is lower than distance between 1
and 3
).
Label encoding is actually excellent when you have ordinal variable.
For example, if you have a value Age = ["Child", "Teenager", "Young Adult", "Adult", "Old"]
,
then using Label Encoding is perfect. Child
is closer than Teenager
than it is from Young Adult
. You have a natural order on your variables
Let's take back the previous example of Animal = ["Dog", "Cat", "Turtle"]
.
It will create as much variable as classes you encounter. In my example, it will create 3 binary variables : Dog, Cat and Turtle
. Then if you have Animal = "Dog"
, encoding will make it Dog = 1, Cat = 0, Turtle = 0
.
Then you can give this to your model, and he will never interpret that Dog
is closer from Cat
than from Turtle
.
But there are also cons to OneHotEncoding. If you have a categorical variable encountering 50 kind of classes
eg : Dog, Cat, Turtle, Fish, Monkey, ...
then it will create 50 binary variables, which can cause complexity issues. In this case, you can create your own classes and manually change variable
eg : regroup Turtle, Fish, Dolphin, Shark
in a same class called Sea Animals
and then appy a OneHotEncoding.
You can accomplish this (if I understand what you are trying to do) using dynamic SQL.
The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.
So you can use something like this approach:
SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue
+ ' AS fld1 FROM tbl' + @KeyValue
EXEC (@stmt)
First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:
'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'
At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE
(or EXEC
for short).
The old-school sp_executesql
procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.
FOLLOWUP
EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.
Consider what would happen if @KeyValue
contained the string:
'1 AS foo; DROP TABLE students; -- '
The string we would produce as a SQL statement would be:
'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'
When we EXECUTE that string as a SQL statement:
INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...
And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)
One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'
. If an illegal character is found, then reject the value, and exit without executing any SQL.
If it's a single String argument, do:
joinPoint.getArgs()[0];
A one-liner command to delete both local, and remote:
D=branch-name; git branch -D $D; git push origin :$D
Or add the alias below to your ~/.gitconfig. Usage: git kill branch-name
[alias]
kill = "!f(){ git branch -D \"$1\"; git push origin --delete \"$1\"; };f"
