I use inline styles extensively within my React components. I find it so much clearer to colocate styles within components because it's always clear what styles the component does and doesn't have. Plus having the full power of Javascript at hand really simplifies more complex styling needs.
I wasn't convinced at first but after dabbling in it for several months, I'm fully converted and am in process of converting all my CSS to inline or other JS-driven css methods.
This presentation by Facebook employee and React contributor "vjeux" is really helpful as well — https://speakerdeck.com/vjeux/react-css-in-js
x = 10;
if(x > 100 ) console.log('over 100')
else if (x > 90 ) console.log('over 90')
else if (x > 50 ) console.log('over 50')
else if (x > 9 ) console.log('over 9')
else console.log('lower 9')
One subtle but significant difference is in the way the two libraries approach scope. Mustache will fall back to parent scope if it can't find a variable within the current context; Handlebars will return a blank string.
This is barely mentioned in the GitHub README, where there's one line for it:
Handlebars deviates from Mustache slightly in that it does not perform recursive lookup by default.
However, as noted there, there is a flag to make Handlebars behave in the same way as Mustache -- but it affects performance.
This has an effect on the way you can use #
variables as conditionals.
For example in Mustache you can do this:
{{#variable}}<span class="text">{{variable}}</span>{{/variable}}
It basically means "if variable exists and is truthy, print a span with the variable in it". But in Handlebars, you would either have to:
{{this}}
instead{{../variable}}
to get back out to relevant scopevariable
value within the parent variable
objectMore details on this, if you want them, here.
it is for testing JavaScript. Amazingly, at barely five or six lines, this code provides a great level of power and control over your code, when testing.
The assert function accepts two parameters:
outcome: A boolean, which references whether your test passed or failed
description: A short description of your test.
The assert function then simply creates a list item, applies a class of either “pass” or “fail,” dependent upon whether your test returned true or false, and then appends the description to the list item. Finally, that block of coded is added to the page. It’s crazy simple, but works perfectly.
Here is the code that can be used to reverse a String.
public static void main(String[] args) {
String aString = "noun";
int size = aString.length();
String reversed = "";
for (int i=size-1;i>=0;i--){
reversed = reversed+ aString.charAt(i);
if (i == 0)
System.out.println(reversed);
}
}
you can also watch the video to better understand the concepts that are needed https://www.youtube.com/watch?v=KaoA0o2Tfi4
You can use this command,
adb shell dumpsys activity
You can find current activity name in activity stack.

I think your best bet would be to use a combination of absolute and relative positioning.
Here's a fiddle: http://jsfiddle.net/PKVza/2/
given your html:
<div class="row">
<div class="col-sm-6">
<img src="~/Images/MyLogo.png" alt="Logo" />
</div>
<div class="bottom-align-text col-sm-6">
<h3>Some Text</h3>
</div>
</div>
use the following CSS:
@media (min-width: 768px ) {
.row {
position: relative;
}
.bottom-align-text {
position: absolute;
bottom: 0;
right: 0;
}
}
EDIT - Fixed CSS and JSFiddle for mobile responsiveness and changed the ID to a class.
I got the same error because of a simple typo in vhost.conf. Remember to make sure you don't have any errors in the config files.

Please use @Frank's a one line solution:
new Date(SECONDS * 1000).toISOString().substr(11, 8)
It is by far the best solution.
HttpClient-4.5,Use TLSv1.2 ,You must code like this:
//Set the https use TLSv1.2
private static Registry<ConnectionSocketFactory> getRegistry() throws KeyManagementException, NoSuchAlgorithmException {
SSLContext sslContext = SSLContexts.custom().build();
SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext,
new String[]{"TLSv1.2"}, null, SSLConnectionSocketFactory.getDefaultHostnameVerifier());
return RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", PlainConnectionSocketFactory.getSocketFactory())
.register("https", sslConnectionSocketFactory)
.build();
}
public static void main(String... args) {
try {
//Set the https use TLSv1.2
PoolingHttpClientConnectionManager clientConnectionManager = new PoolingHttpClientConnectionManager(getRegistry());
clientConnectionManager.setMaxTotal(100);
clientConnectionManager.setDefaultMaxPerRoute(20);
HttpClient client = HttpClients.custom().setConnectionManager(clientConnectionManager).build();
//Then you can do : client.execute(HttpGet or HttpPost);
} catch (KeyManagementException | NoSuchAlgorithmException e) {
e.printStackTrace();
}
}
With the arrival of the HTTPClient
API, not only was the Http
API replaced, but a new one was added, the HttpInterceptor
API.
AFAIK one of its goals is to add default behavior to all the HTTP outgoing requests and incoming responses.
So assumming that you want to add a default error handling behavior, adding .catch()
to all of your possible http.get/post/etc methods is ridiculously hard to maintain.
This could be done in the following way as example using a HttpInterceptor
:
import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HttpErrorResponse, HTTP_INTERCEPTORS } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { _throw } from 'rxjs/observable/throw';
import 'rxjs/add/operator/catch';
/**
* Intercepts the HTTP responses, and in case that an error/exception is thrown, handles it
* and extract the relevant information of it.
*/
@Injectable()
export class ErrorInterceptor implements HttpInterceptor {
/**
* Intercepts an outgoing HTTP request, executes it and handles any error that could be triggered in execution.
* @see HttpInterceptor
* @param req the outgoing HTTP request
* @param next a HTTP request handler
*/
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
return next.handle(req)
.catch(errorResponse => {
let errMsg: string;
if (errorResponse instanceof HttpErrorResponse) {
const err = errorResponse.message || JSON.stringify(errorResponse.error);
errMsg = `${errorResponse.status} - ${errorResponse.statusText || ''} Details: ${err}`;
} else {
errMsg = errorResponse.message ? errorResponse.message : errorResponse.toString();
}
return _throw(errMsg);
});
}
}
/**
* Provider POJO for the interceptor
*/
export const ErrorInterceptorProvider = {
provide: HTTP_INTERCEPTORS,
useClass: ErrorInterceptor,
multi: true,
};
// app.module.ts
import { ErrorInterceptorProvider } from 'somewhere/in/your/src/folder';
@NgModule({
...
providers: [
...
ErrorInterceptorProvider,
....
],
...
})
export class AppModule {}
Some extra info for OP: Calling http.get/post/etc without a strong type isn't an optimal use of the API. Your service should look like this:
// These interfaces could be somewhere else in your src folder, not necessarily in your service file
export interface FooPost {
// Define the form of the object in JSON format that your
// expect from the backend on post
}
export interface FooPatch {
// Define the form of the object in JSON format that your
// expect from the backend on patch
}
export interface FooGet {
// Define the form of the object in JSON format that your
// expect from the backend on get
}
@Injectable()
export class DataService {
baseUrl = 'http://localhost'
constructor(
private http: HttpClient) {
}
get(url, params): Observable<FooGet> {
return this.http.get<FooGet>(this.baseUrl + url, params);
}
post(url, body): Observable<FooPost> {
return this.http.post<FooPost>(this.baseUrl + url, body);
}
patch(url, body): Observable<FooPatch> {
return this.http.patch<FooPatch>(this.baseUrl + url, body);
}
}
Returning Promises
from your service methods instead of Observables
is another bad decision.
And an extra piece of advice: if you are using TYPEscript, then start using the type part of it. You lose one of the biggest advantages of the language: to know the type of the value that you are dealing with.
If you want a, in my opinion, good example of an angular service, take a look at the following gist.
The [:-1]
removes the last element. Instead of
a[3:-1]
write
a[3:]
You can read up on Python slicing notation here: Explain Python's slice notation
NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.
You should be able to use normal C methods in math.
#include <cmath>
pow(2,3)
if you're on a unix-like system, man cmath
Is that what you're asking?

I once had to use CDATA when my xml element needed to store HTML code. Something like
<codearea>
<![CDATA[
<div> <p> my para </p> </div>
]]>
</codearea>
So CDATA means it will ignore any character which could otherwise be interpreted as XML tag like < and > etc.
If you use docker-compose just set UPLOAD_LIMIT
phpmyadmin:
image: phpmyadmin/phpmyadmin
environment:
UPLOAD_LIMIT: 1G
This is a quirk of the C grammar. A label (Cleanup:
) is not allowed to appear immediately before a declaration (such as char *str ...;
), only before a statement (printf(...);
). In C89 this was no great difficulty because declarations could only appear at the very beginning of a block, so you could always move the label down a bit and avoid the issue. In C99 you can mix declarations and code, but you still can't put a label immediately before a declaration.
You can put a semicolon immediately after the label's colon (as suggested by Renan) to make there be an empty statement there; this is what I would do in machine-generated code. Alternatively, hoist the declaration to the top of the function:
int main (void)
{
char *str;
printf("Hello ");
goto Cleanup;
Cleanup:
str = "World\n";
printf("%s\n", str);
return 0;
}
Using INDEX
and MATCH
for binning. Easier to maintain if we have more bins.
=INDEX({"Text 1","Text 2","Text 3"},MATCH(A2,{0,5,21,100}))
Action is a delegate (pointer) to a method, that takes zero, one or more input parameters, but does not return anything.
Func is a delegate (pointer) to a method, that takes zero, one or more input parameters, and returns a value (or reference).
Predicate is a special kind of Func often used for comparisons.
Though widely used with Linq, Action and Func are concepts logically independent of Linq. C++ already contained the basic concept in form of typed function pointers.
Here is a small example for Action and Func without using Linq:
class Program
{
static void Main(string[] args)
{
Action<int> myAction = new Action<int>(DoSomething);
myAction(123); // Prints out "123"
// can be also called as myAction.Invoke(123);
Func<int, double> myFunc = new Func<int, double>(CalculateSomething);
Console.WriteLine(myFunc(5)); // Prints out "2.5"
}
static void DoSomething(int i)
{
Console.WriteLine(i);
}
static double CalculateSomething(int i)
{
return (double)i/2;
}
}
Actually.
Why are you checking the URL? That's no guarantee what you're going to get is an image, and no guarantee that the things you're rejecting aren't images. Try performing a HEAD request on it, and see what content-type it actually is.
Let consider that your data are in the file values.txt
and that you want to import them in the database table myTable
then the following query does the job
COPY myTable FROM 'value.txt' (DELIMITER('|'));
https://www.postgresql.org/docs/current/static/sql-copy.html
Though this question is rather old, here's a answer :)
What you are asking for can be achieved by using jQuery's .click() event method and .on() event method
So this could be the code:
// Set the global variables
var userImage = $("#img-giLkojRpuK");
var hangoutButton = $("#hangout-giLkojRpuK");
$(document).ready(function() {
// When the document is ready/loaded, execute function
// Hide hangoutButton
hangoutButton.hide();
// Assign "click"-event-method to userImage
userImage.on("click", function() {
console.log("in onclick");
hangoutButton.click();
});
});
You can close a figure by calling matplotlib.pyplot.close
, for example:
from numpy import *
import matplotlib.pyplot as plt
from scipy import *
t = linspace(0, 0.1,1000)
w = 60*2*pi
fig = plt.figure()
plt.plot(t,cos(w*t))
plt.plot(t,cos(w*t-2*pi/3))
plt.plot(t,cos(w*t-4*pi/3))
plt.show()
plt.close(fig)
You can also close all open figures by calling matplotlib.pyplot.close("all")
For IPv4, you could get away with storing the 4 raw bytes of the IP address (each of the numbers between the periods in an IP address are 0-255, i.e., one byte). But then you would have to translate going in and out of the DB and that's messy.
IPv6 addresses are 128 bits (as opposed to 32 bits of IPv4 addresses). They are usually written as 8 groups of 4 hex digits separated by colons: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
. 39 characters is appropriate to store IPv6 addresses in this format.
Edit: However, there is a caveat, see @Deepak's answer for details about IPv4-mapped IPv6 addresses. (The correct maximum IPv6 string length is 45 characters.)
Easiest solution:
kill $(lsof -ti:3000,3001,8080)
For single port:
kill $(lsof -ti:3000)
#3000 is the port to be freed
Kill multiple ports with single line command:
kill $(lsof -ti:3000,3001)
#here multiple ports 3000 and 3001 are the ports to be freed
lsof -ti:3000
82500 (Process ID)

ord()
will not work because your end string is two characters long.
Returns the ASCII value of the first character of string.
From my testing, you need to check that the end
string doesn't get "stepped over". The perl-style character incrementation is a cool method, but it is a single-stepping method. For this reason, an inner loop helps it along when necessary. This is actually not a bother, in fact, it is useful because we need to check if the loop(s) should be broken on each single step.
Code: (Demo)
function excelCols($letter,$end,$step=1){ // function doesn't check that $end is "later" than $letter
if($step==0)return []; // prevent infinite loop
do{
$letters[]=$letter; // store letter
for($x=0; $x<$step; ++$x){ // increment in accordance with $step declaration
if($letter===$end)break(2); // break if end is "stepped on"
++$letter;
}
}while(true);
return $letters;
}
echo implode(' ',excelCols('A','JJ',4));
echo "\n --- \n";
echo implode(' ',excelCols('A','BB',3));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',1));

C and C++ don't have a standard library for HTTP or even for socket connections. Over the years some portable libraries have been developed. The most widely used, as others have said, is libcurl.
Here is a list of alternatives to libcurl (coming from the libcurl's web site).
Also, for Linux, this is a simple HTTP client. You could implement your own simple HTTP GET client, but this won't work if there are authentication or redirects involved or if you need to work behind a proxy. For these cases you need a full-blown library like libcurl.
For source code with libcurl, this is the closest to what you want (Libcurl has many examples). Look at the main function. The html content will be copied to the buffer, after a successfully connection. Just replace parseHtml with your own function.
If you already have a table and can't/don't want to recreate it for whatever reason, use indexes:
CREATE UNIQUE INDEX my_index ON my_table(col_1, col_2);

The simplest code to align the iframe element:

In order:
You can replace target-action with a closure (block in Objective-C) by adding a helper closure wrapper (ClosureSleeve) and adding it as an associated object to the control so it gets retained. That way you can pass any parameters.
class ClosureSleeve {
let closure: () -> ()
init(attachTo: AnyObject, closure: @escaping () -> ()) {
self.closure = closure
objc_setAssociatedObject(attachTo, "[\(arc4random())]", self, .OBJC_ASSOCIATION_RETAIN)
}
@objc func invoke() {
closure()
}
}
extension UIControl {
func addAction(for controlEvents: UIControlEvents, action: @escaping () -> ()) {
let sleeve = ClosureSleeve(attachTo: self, closure: action)
addTarget(sleeve, action: #selector(ClosureSleeve.invoke), for: controlEvents)
}
}
Usage:
button.addAction(for: .touchUpInside) {
self.switchToNewsDetails(parameter: i)
}
It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.
The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:
You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:
Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:
#toolbar=0&navpanes=0
So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.
string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);
You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.
You have several options for iterating over a dictionary.
If you iterate over the dictionary itself (for team in league
), you will be iterating over the keys of the dictionary. When looping with a for loop, the behavior will be the same whether you loop over the dict (league
) itself, or league.keys()
:
for team in league.keys():
runs_scored, runs_allowed = map(float, league[team])
You can also iterate over both the keys and the values at once by iterating over league.items()
:
for team, runs in league.items():
runs_scored, runs_allowed = map(float, runs)
You can even perform your tuple unpacking while iterating:
for team, (runs_scored, runs_allowed) in league.items():
runs_scored = float(runs_scored)
runs_allowed = float(runs_allowed)
Return as a tuple, e.g.
def foo (a):
x=a
y=a*2
return (x,y)
This worked for me:
JSONArray jsonarr = (JSONArray) new JSONParser().parse(new InputStreamReader(Nameofclass.class.getResourceAsStream(pathToJSONFile)));
JSONObject jsonobj = (JSONObject) new JSONParser().parse(new InputStreamReader(Nameofclass.class.getResourceAsStream(pathToJSONFile)));
In my case I misspelled the name of the branch. Locally I did something like:
git push --set-upstream origin feture/my-feature
where my branch name was missing the a
in feature
. I corrected it to:
git push --set-upstream origin feature/my-feature
And everything worked fine.
Simply type:
list(my_set)
This will turn a set in the form {'1','2'} into a list in the form ['1','2'].
Really it's interesting. You need just use javax-mail.jar of "com.sun" not "javax.mail".

As strtotime requires specific input format, DateTime::createFromFormat could be used (php 5.3+ is required)
// set timezone to user timezone
date_default_timezone_set($str_user_timezone);
// create date object using any given format
$date = DateTime::createFromFormat($str_user_dateformat, $str_user_datetime);
// convert given datetime to safe format for strtotime
$str_user_datetime = $date->format('Y-m-d H:i:s');
// convert to UTC
$str_UTC_datetime = gmdate($str_server_dateformat, strtotime($str_user_datetime));
// return timezone to server default
date_default_timezone_set($str_server_timezone);
Short list of some of the major differences:
bool
, true
and false
, Objective-C uses BOOL
, YES
and NO
.void*
and nullptr
, Objective-C prefers id
and nil
.SEL
) as an approximate equivalent to function pointers.nil
, unlike C++ which will crash if you try to call a member function of nullptr
self
, and allows class initialisers (similar to constructors) to return a completely different class if desired. Contrast to C++, where if you create a new instance of a class (either implicitly on the stack, or explicitly through new
) it is guaranteed to be of the type you originally specified.int foo (void)
and int foo (int)
define an implicit overload of the method foo
, but to achieve the same in Objective-C requires the explicit overloads - (int) foo
and - (int) foo:(int) intParam
. This is due to Objective-C's named parameters being functionally equivalent to C++'s name mangling.alloc
message, or implicitly in an appropriate factory method).In my opinion, probably the biggest difference is the syntax. You can achieve essentially the same things in either language, but in my opinion the C++ syntax is simpler while some of Objective-C's features make certain tasks (such as GUI design) easier thanks to dynamic dispatch.
Probably plenty of other things too that I've missed, I'll update with any other things I think of. Other than that, can highly recommend the guide LiraNuna pointed you to. Incidentally, another site of interest might be this.
I should also point out that I'm just starting learning Objective-C myself, and as such a lot of the above may not quite be correct or complete - I apologise if that's the case, and welcome suggestions for improvement.
EDIT: updated to address the points raised in the following comments, added a few more items to the list.
The getTimezoneOffset() method returns the time zone difference, in minutes, from current locale (host system settings) to UTC.
Source: MDN web docs
This means that the offset is positive if the local timezone is behind UTC, and negative if it is ahead. For example, for time zone UTC+02:00, -120 will be returned.
let d = new Date();
console.log(d);
d.setTime(d.getTime() + (d.getTimezoneOffset() * 60000));
console.log(d);
_x000D_
NOTE: This will shift the date object time to UTC±00:00 and not convert its timezone so the date object timezone will still the same but the value will be in UTC±00:00.
The traditional way to do this is to use the Flags
attribute on an enum
:
[Flags]
public enum Names
{
None = 0,
Susan = 1,
Bob = 2,
Karen = 4
}
Then you'd check for a particular name as follows:
Names names = Names.Susan | Names.Bob;
// evaluates to true
bool susanIsIncluded = (names & Names.Susan) != Names.None;
// evaluates to false
bool karenIsIncluded = (names & Names.Karen) != Names.None;
Logical bitwise combinations can be tough to remember, so I make life easier on myself with a FlagsHelper
class*:
// The casts to object in the below code are an unfortunate necessity due to
// C#'s restriction against a where T : Enum constraint. (There are ways around
// this, but they're outside the scope of this simple illustration.)
public static class FlagsHelper
{
public static bool IsSet<T>(T flags, T flag) where T : struct
{
int flagsValue = (int)(object)flags;
int flagValue = (int)(object)flag;
return (flagsValue & flagValue) != 0;
}
public static void Set<T>(ref T flags, T flag) where T : struct
{
int flagsValue = (int)(object)flags;
int flagValue = (int)(object)flag;
flags = (T)(object)(flagsValue | flagValue);
}
public static void Unset<T>(ref T flags, T flag) where T : struct
{
int flagsValue = (int)(object)flags;
int flagValue = (int)(object)flag;
flags = (T)(object)(flagsValue & (~flagValue));
}
}
This would allow me to rewrite the above code as:
Names names = Names.Susan | Names.Bob;
bool susanIsIncluded = FlagsHelper.IsSet(names, Names.Susan);
bool karenIsIncluded = FlagsHelper.IsSet(names, Names.Karen);
Note I could also add Karen
to the set by doing this:
FlagsHelper.Set(ref names, Names.Karen);
And I could remove Susan
in a similar way:
FlagsHelper.Unset(ref names, Names.Susan);
*As Porges pointed out, an equivalent of the IsSet
method above already exists in .NET 4.0: Enum.HasFlag
. The Set
and Unset
methods don't appear to have equivalents, though; so I'd still say this class has some merit.
Note: Using enums is just the conventional way of tackling this problem. You can totally translate all of the above code to use ints instead and it'll work just as well.
Here is a fairly easy to understand version using method syntax:
IEnumerable<JoinPair> outerLeft =
lefts.SelectMany(l =>
rights.Where(r => l.Key == r.Key)
.DefaultIfEmpty(new Item())
.Select(r => new JoinPair { LeftId = l.Id, RightId = r.Id }));
Long i = 1000000;
String s = i + "";
Double d = Double.parseDouble(s);
Float f = Float.parseFloat(s);
This way we can convert Long type to Double or Float or Int without any problem because it's easy to convert string value to Double or Float or Int.
I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .
While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

Simply right click on your file in the Visual Studio Code side-panel (explorer) and select the first option open to the side.
A perl oneliner would do: perl -i.bak -pe 's/[^[:ascii:]]//g' <your file>
-i
says that the file is going to be edited inplace, and the backup is going to be saved with extension .bak
.
You need to decide exactly what you want to do - and preferably explain it a bit more clearly.
If you know which file you want the output of the executed command to go to, then:
If you want the parent to read the output from the child, arrange for the child to pipe its output back to the parent.
if no luck with above try to it a class or even id something like textarea.foo and then your style. or try to !important
You can just echo all the HTML as normal:
<?php
echo '<input type="button" onclick="alert(\'Clicky!\')"/>';
?>
JQuery:
$(function () {
$('.SendEmail').click(function (event) {
var email = '[email protected]';
var subject = 'Test';
var emailBody = 'Hi Sample,';
var attach = 'path';
document.location = "mailto:"+email+"?subject="+subject+"&body="+emailBody+
"?attach="+attach;
});
});
HTML:
<button class="SendEmail">Send Email</button>
Export you Java Project as an Runnable Jar file rather than Jar.
I exported my project as Jar and even though the Manifest was present it gave me the error no main manifest attribute in jar even though the Manifest file was present in the Jar. However there is only one entry in the Manifest file and it didn't specify the Main class or Function to execute or any dependent JAR's
After exporting it as Runnable Jar file it works as expected.
I'm not sure when this was written, but currently to add or remove a default from a column in a migration, you can use the following:
change_column_null :products, :name, false
Rails 5:
change_column_default :products, :approved, from: true, to: false
http://edgeguides.rubyonrails.org/active_record_migrations.html#changing-columns
Rails 4.2:
change_column_default :products, :approved, false
http://guides.rubyonrails.org/v4.2/active_record_migrations.html#changing-columns
Which is a neat way of avoiding looking through your migrations or schema for the column specifications.
You can flush hosts local MySQL using following command:
mysqladmin -u [username] -p flush-hosts
**** [MySQL password]
or
mysqladmin flush-hosts -u [username] -p
**** [MySQL password]
Though Amazon RDS database server is on network then use the following command as like as flush network MySQL server:
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
In additional suggestion you can permanently solve blocked of many connections error problem by editing my.ini file[Mysql configuration file]
change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";
This is how you use the TensorBoard callback:
from keras.callbacks import TensorBoard
tensorboard = TensorBoard(log_dir='./logs', histogram_freq=0,
write_graph=True, write_images=False)
# define model
model.fit(X_train, Y_train,
batch_size=batch_size,
epochs=nb_epoch,
validation_data=(X_test, Y_test),
shuffle=True,
callbacks=[tensorboard])
Hello i have got the same issue i was getting Optional(3) So, i have tried this below code
cell.lbl_Quantity.text = "(data?.quantity!)" //"Optional(3)"
let quantity = data?.quantity
cell.lbl_Quantity.text = "(quantity!)" //"3"
It was changing the line endings (from Windows CRLF to Unix LF) in the .htaccess
file that fixed it for me.
You have a scalar valued function as opposed to a table valued function. The from clause is used for tables. Just query the value directly in the column list.
select dbo.fun_functional_score('01091400003')
Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.
Try using this command to allow a port
sudo ufw allow 1701
To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:
nc -l 1701
Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.
rtrim(lastname)+','+rtrim(firstname) as [Person Name]
from Table
the result will show lastname,firstname as one column header !
Updated Answer
* Updated answer which support the v2.1.1** bootstrap version stylesheet.
**But be careful because this solution has been removed from v3
Just wanted to point out that this solution is not needed anymore as the latest bootstrap now supports multi-level dropdowns by default. You can still use it if you're on older versions but for those who updated to the latest (v2.1.1 at the time of writing) it is not needed anymore. Here is a fiddle with the updated default multi-level dropdown straight from the documentation:
http://jsfiddle.net/2Smgv/2858/
Original Answer
There have been some issues raised on submenu support over at github and they are usually closed by the bootstrap developers, such as this one, so i think it is left to the developers using the bootstrap to work something out. Here is a demo i put together showing you how you can hack together a working sub-menu.
Relevant code
CSS
.dropdown-menu .sub-menu {
left: 100%;
position: absolute;
top: 0;
visibility: hidden;
margin-top: -1px;
}
.dropdown-menu li:hover .sub-menu {
visibility: visible;
display: block;
}
.navbar .sub-menu:before {
border-bottom: 7px solid transparent;
border-left: none;
border-right: 7px solid rgba(0, 0, 0, 0.2);
border-top: 7px solid transparent;
left: -7px;
top: 10px;
}
.navbar .sub-menu:after {
border-top: 6px solid transparent;
border-left: none;
border-right: 6px solid #fff;
border-bottom: 6px solid transparent;
left: 10px;
top: 11px;
left: -6px;
}
Created my own .sub-menu
class to apply to the 2-level drop down menus, this way we can position them next to our menu items. Also modified the arrow to display it on the left of the submenu group.
If you are looking for a very simple lastIndex lookup with RegExp and don't care if it mimics lastIndexOf to the last detail, this may catch your attention.
I simply reverse the string, and subtract the first occurence index from length - 1. It happens to pass my test, but I think there could arise a performance issue with long strings.
interface String {
reverse(): string;
lastIndex(regex: RegExp): number;
}
String.prototype.reverse = function(this: string) {
return this.split("")
.reverse()
.join("");
};
String.prototype.lastIndex = function(this: string, regex: RegExp) {
const exec = regex.exec(this.reverse());
return exec === null ? -1 : this.length - 1 - exec.index;
};
Just for the completeness, we can also avoid declaring private_class_method in a separate line. I personally don't like this usage but good to know that it exists.
private_class_method def self.method_name
....
end
In my case I was sending in correct object in ResponseEntity<>().
Correct :
@PostMapping(value = "/get-customer-details", produces = { MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<?> getCustomerDetails(@RequestBody String requestMessage) throws JSONException {
JSONObject jsonObject = new JSONObject();
jsonObject.put("customerId", "123");
jsonObject.put("mobileNumber", "XXX-XXX-XXXX");
return new ResponseEntity<>(jsonObject.toString(), HttpStatus.OK);
}
Incorrect :
return new ResponseEntity<>(jsonObject, HttpStatus.OK);
Because, jsonObject's toString() method "Encodes the jsonObject as a compact JSON string". Therefore, Spring returns json string directly without any further serialization.
When we send jsonObject instead, Spring tries to serialize it based on produces method used in RequestMapping and fails due to it "Could not find acceptable representation".
You can use substr
and strrchr
:
$url = 'http://www.vimeo.com/1234567';
$str = substr(strrchr($url, '/'), 1);
echo $str; // Output: 1234567
This should work:
your_str='GenFiltEff=7.092200e-01'
echo $your_str | cut -d "=" -f2
Here's a solution that's part of the standard library:
from distutils.dir_util import copy_tree
copy_tree("/a/b/c", "/x/y/z")
See this similar question.
Thanks to DroidT, I made this:
I realize that if the Fragment does not execute onCreateView(), its view is not instantiated. So, if the fragment on back stack did not create its views, I save the last stored state, otherwise I build my own bundle with the data I want to save/restore.
1) Extend this class:
import android.os.Bundle;
import android.support.v4.app.Fragment;
public abstract class StatefulFragment extends Fragment {
private Bundle savedState;
private boolean saved;
private static final String _FRAGMENT_STATE = "FRAGMENT_STATE";
@Override
public void onSaveInstanceState(Bundle state) {
if (getView() == null) {
state.putBundle(_FRAGMENT_STATE, savedState);
} else {
Bundle bundle = saved ? savedState : getStateToSave();
state.putBundle(_FRAGMENT_STATE, bundle);
}
saved = false;
super.onSaveInstanceState(state);
}
@Override
public void onCreate(Bundle state) {
super.onCreate(state);
if (state != null) {
savedState = state.getBundle(_FRAGMENT_STATE);
}
}
@Override
public void onDestroyView() {
savedState = getStateToSave();
saved = true;
super.onDestroyView();
}
protected Bundle getSavedState() {
return savedState;
}
protected abstract boolean hasSavedState();
protected abstract Bundle getStateToSave();
}
2) In your Fragment, you must have this:
@Override
protected boolean hasSavedState() {
Bundle state = getSavedState();
if (state == null) {
return false;
}
//restore your data here
return true;
}
3) For example, you can call hasSavedState in onActivityCreated:
@Override
public void onActivityCreated(Bundle state) {
super.onActivityCreated(state);
if (hasSavedState()) {
return;
}
//your code here
}
As of jQuery 1.7, .on()
is now the preferred method of binding events, rather than .bind()
:
From http://api.jquery.com/bind/:
As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().
The documentation page is located at http://api.jquery.com/on/
Here, I would like to add that if you are reading window handle that is HWND of a process then that process should not be running in a debugging otherwise it will not find the window handle by using FindWindowEx.
Ensure the IDE recognizes that you have the package. It didn't on mine even after downloading 28, so I uninstalled then reinstalled it after realizing it wasn't showing up under File-Project Structure-Modules-App as a choice for SDK.
On top of that, you may want to change your build path to match.
Slightly related, the latest updates seem able to compile when I forced an update all the way to 28 for CompileSDK, and not just up to the new API 26 min requirement from Google Play. This is related to dependencies though, and might not affect yours
This means that there is a line which starts with a space, tab, or some other whitespace without having a target in front of it.
You can either change the thread identity, or P/Invoke WNetAddConnection2. I prefer the latter, as I sometimes need to maintain multiple credentials for different locations. I wrap it into an IDisposable and call WNetCancelConnection2 to remove the creds afterwards (avoiding the multiple usernames error):
using (new NetworkConnection(@"\\server\read", readCredentials))
using (new NetworkConnection(@"\\server2\write", writeCredentials)) {
File.Copy(@"\\server\read\file", @"\\server2\write\file");
}
First of all you missed ScriptService attribute to add in webservice.
[ScriptService]
After then try following method to call webservice via JSON.
var webAddr = "http://Domain/VBRService.asmx/callJson"; var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr); httpWebRequest.ContentType = "application/json; charset=utf-8"; httpWebRequest.Method = "POST"; using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { string json = "{\"x\":\"true\"}"; streamWriter.Write(json); streamWriter.Flush(); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); return result; }
By reading online (tables tutorial) it seems tables behave like arrays so you're looking for:
Way1
names = {'John', 'Joe', 'Steve'}
for i = 1,3 do print( names[i] ) end
Way2
names = {'John', 'Joe', 'Steve'}
for k,v in pairs(names) do print(v) end
Way1 uses the table index/key
, on your table names
each element has a key starting from 1, for example:
names = {'John', 'Joe', 'Steve'}
print( names[1] ) -- prints John
So you just make i
go from 1 to 3.
On Way2 instead you specify what table you want to run and assign a variable for its key and value for example:
names = {'John', 'Joe', myKey="myValue" }
for k,v in pairs(names) do print(k,v) end
prints the following:
1 John
2 Joe
myKey myValue
For me, this worked in Ubuntu 14.04 and for php5.6:
$ sudo apt-get install php5.6-mbstring
Each java.util.List implementation is required to preserve the order so either you are using ArrayList, LinkedList, Vector, etc. each of them are ordered collections and each of them preserve the order of insertion (see http://download.oracle.com/javase/1.4.2/docs/api/java/util/List.html)
You can use a utility called codel
(link). It's a simple Python module to count lines with colorful formatting.
pip install codel
To count lines of C++ files (with .cpp
and .h
extensions), use:
codel count -e .cpp .h
You can also ignore some files/folder with the .gitignore format:
codel count -e .py -i tests/**
It will ignore all the files in the tests/
folder.
The output looks like:
You also can shorten the output with the -s
flag. It will hide the information of each file and show only information about each extension. The example is below:
$_='~s/blue/red/g';
Uh, what??
Just
s/blue/red/g;
or, if you insist on using a variable (which is not necessary when using $_, but I just want to show the right syntax):
$_ =~ s/blue/red/g;
String path ="AnyDirectory/subFolder/last.htm";
int pos = path.lastIndexOf("/") + 1;
path.substring(pos, path.length()-pos) ;
Now you have the last.htm in the path string.
This will get your buttons and labels next to each other, at least. I believe the second part can't be done in css alone, and will need javascript. I found a page that might help you with that part as well, but I don't have time right now to try it out: http://www.webmasterworld.com/forum83/6942.htm
<style type="text/css">
.input input {

}
.input label {

}
</style>
<div class="input radio">
<fieldset>
<legend>What color is the sky?</legend>
<input type="hidden" name="data[Submit][question]" value="" id="SubmitQuestion" />
<input type="radio" name="data[Submit][question]" id="SubmitQuestion1" value="1" />
<label for="SubmitQuestion1">A strange radient green.</label>
<input type="radio" name="data[Submit][question]" id="SubmitQuestion2" value="2" />

<input type="radio" name="data[Submit][question]" id="SubmitQuestion3" value="3" />
<label for="SubmitQuestion3">A perfect glittering blue</label>
</fieldset>
</div>
you can create selector file in res/drawable
example: res/drawable/selector_button.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/btn_disabled" android:state_enabled="false" />
<item android:drawable="@drawable/btn_enabled" />
</selector>
and in layout activity, fragment or etc
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/selector_bg_rectangle_black"/>
Is there a prize for being lazy and using the transpose function of NumPy arrays? ;)
import numpy as np
a = np.array([(1,2,3), (4,5,6)])
b = a.transpose()
The first way is "more correct", what intention could there be to express? If the code ends, it ends. That's pretty clear, in my opinion.
I don't understand what could possibly be confusing and need clarification. If there's no looping construct being used, then what could possibly happen other than that the function stops executing?
I would be severly annoyed by such a pointless extra return
statement at the end of a void
function, since it clearly serves no purpose and just makes me feel the original programmer said "I was confused about this, and now you can be too!" which is not very nice.

Reviving an old question, but I wanted to post an iteration on @adeneo's answer. That answer is completely general, but for this use case it could be more efficient (it's slow on my machine with an array of a few thousand objects). If you know the specific properties of the objects you need to compare, just compare them directly:
var sl = standardsList;
var out = [];
for (var i = 0, l = sl.length; i < l; i++) {
var unique = true;
for (var j = 0, k = out.length; j < k; j++) {
if ((sl[i].Grade === out[j].Grade) && (sl[i].Domain === out[j].Domain)) {
unique = false;
}
}
if (unique) {
out.push(sl[i]);
}
}
console.log(sl.length); // 10
console.log(out.length); // 5
strip
only removes characters from the beginning and end of a string. You want to use replace
:
str2 = str.replace("\n", "")
re.sub('\s{2,}', ' ', str) # To remove more than one space
The hosts
file is for host name resolution only (on Windows as well as on Unix-like systems). You cannot put port numbers in there, and there is no way to do what you want with generic OS-level configuration - the browser is what selects the port to choose.
So use bookmarks or something like that.
(Some firewall/routing software might allow outbound port redirection, but that doesn't really sound like an appealing option for this.)
Maybe you mean like this? I like to make an object and use Format-Table:
> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table
Name Age Info
---- --- ----
Joe 32 something about him
This will put all objects you have in the array in columns according to their properties.
Tip: Using -auto
sizes the table better
> $array | Format-Table -Auto
Name Age Info
---- --- ----
Joe 32 something about him
You can also specify which properties you want in the table. Just separate each property name with a comma:
> $array | Format-Table Name, Age -Auto
Name Age
---- ---
Joe 32
Extending the above post by Tom, if you need a class type declaration and access the singleton instance using a variable, the code below might be of help. I like this notation as the code is little self guiding.
function SingletonClass(){
if ( arguments.callee.instance )
return arguments.callee.instance;
arguments.callee.instance = this;
}
SingletonClass.getInstance = function() {
var singletonClass = new SingletonClass();
return singletonClass;
};
To access the singleton, you would
var singleTon = SingletonClass.getInstance();
Did you try
string.trim();
This is meant to trim all leading and leaning while spaces in the string. Hope this helps.
Edit: (I was not explicit enough)
So, when you string.split(), you will have a string[] - for each of the strings in the array, do a string.trim() and then append it.
String[] tokens = yourString.split(" ");
StringBuffer buff = new StringBuffer();
for (String token : tokens)
{
buff.append(token.trim());
}
Use stringBuffer/Builder instead of appending in the same string.
The most important difference is this:
In case of persist
method, if the entity that is to be managed in the persistence context, already exists in persistence context, the new one is ignored. (NOTHING happened)
But in case of merge
method, the entity that is already managed in persistence context will be replaced by the new entity (updated) and a copy of this updated entity will return back. (from now on any changes should be made on this returned entity if you want to reflect your changes in persistence context)
I know this already has a chosen answer - but I wanted to toss in my two cents. I have a databound dropdown list:
<asp:DropDownList
id="country"
runat="server"
CssClass="selectOne"
DataSourceID="country_code"
DataTextField="Name"
DataValueField="CountryCode_PK"
></asp:DropDownList>
<asp:SqlDataSource
id="country_code"
runat="server"
ConnectionString="<%$ ConnectionStrings:DBConnectionString %>"
SelectCommand="SELECT CountryCode_PK, CountryCode_PK + ' - ' + Name AS N'Name' FROM TBL_Country ORDER BY CountryCode_PK"
></asp:SqlDataSource>
In the codebehind, I have this - (which selects United States by default):
if (this.IsPostBack)
{
//handle posted data
}
else
{
country.SelectedValue = "US";
}
The page initially loads based on the 'US' value rather than trying to worry about a selectedIndex (what if another item is added into the data table - I don't want to have to re-code)
The next approach work to me with Visual Studio 2013 Update 4 1- From Solution Explorer right click on References then select add references 2- Assemblies > Framework > System.Data.OracleClient > OK and after that you free to add using System.Data.OracleClient in your application and deal with database like you do with Sql Server database except changing the prefix from Sql to Oracle as in SqlCommand become OracleCommand for example to link to Oracle XE
OracleConnection oraConnection = new OracleConnection(@"Data Source=XE; User ID=system; Password=*myPass*");
public void Open()
{
if (oraConnection.State != ConnectionState.Open)
{
oraConnection.Open();
}
}
public void Close()
{
if (oraConnection.State == ConnectionState.Open)
{
oraConnection.Close();
}}
and to execute some command like INSERT, UPDATE, or DELETE using stored procedure we can use the following method
public void ExecuteCMD(string storedProcedure, OracleParameter[] param)
{
OracleCommand oraCmd = new OracleCommand();
oraCmd,CommandType = CommandType.StoredProcedure;
oraCmd.CommandText = storedProcedure;
oraCmd.Connection = oraConnection;
if(param!=null)
{
oraCmd.Parameters.AddRange(param);
}
try
{
oraCmd.ExecuteNoneQuery();
}
catch (Exception)
{
MessageBox.Show("Sorry We've got Unknown Error","Connection Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
}
}
Consider UTF-8. In UTF-8 Unicode code points are built from one or more bytes. A class encapsulating a UTF-8 byte array can implement the CharSequence interface but is most decidedly not a String. Certainly you can't pass a UTF-8 byte array where a String is expected but you certainly can pass a UTF-8 wrapper class that implements CharSequence when the contract is relaxed to allow a CharSequence. On my project, I am developing a class called CBTF8Field (Compressed Binary Transfer Format - Eight Bit) to provide data compression for xml and am looking to use the CharSequence interface to implement conversions from CBTF8 byte arrays to/from character arrays (UTF-16) and byte arrays (UTF-8).
The reason I came here was to get a complete understanding of the subsequence contract.
I wanted to encrypt and decrypt the string as a readable string.
Here is a very simple quick example in C# Visual Studio 2019 WinForms based on the answer from @Pradip
.
Right click project > properties > settings > Create a username
and password
setting.
Now you can leverage those settings you just created. Here I save the username
and password
but only encrypt the password
in it's respectable value field in the user.config
file.
Example of the encrypted string in the user.config
file.
<?xml version="1.0" encoding="utf-8"?>

because you are just learning I suggest you practice converting a SELECT joins to UPDATE or DELETE joins. First I suggest you generate a SELECT statement joining these two tables:
SELECT *
FROM tempDataView a
INNER JOIN tempData b
ON a.Name = b.Name
Then note that we have two table aliases a
and b
. Using these aliases you can easily generate UPDATE statement to update either table a or b. For table a you have an answer provided by JW. If you want to update b
, the statement will be:
UPDATE b
SET b.marks = a.marks
FROM tempDataView a
INNER JOIN tempData b
ON a.Name = b.Name
Now, to convert the statement to a DELETE statement use the same approach. The statement below will delete from a
only (leaving b intact) for those records that match by name:
DELETE a
FROM tempDataView a
INNER JOIN tempData b
ON a.Name = b.Name
You can use the SQL Fiddle created by JW as a playground
In Ubuntu you can apply this way,
path = default_storage.save('static/tmp/' + f1.name, ContentFile(f1.read()))
path12 = os.path.join(os.getcwd(), "static/tmp/" + f1.name)
data={} #can be anything u want to pass along with File
file1 = open(path12, 'rb')
header = {"Content-Disposition": "attachment; filename=" + f1.name, "Authorization": "JWT " + token}
res= requests.post(url,data,header)

Like others have mentioned, the Google Places Autocomplete API is missing some important functions. Case in point, Google will not validate that the street number is real, and they also will not put it into a standardized format. So, it is the user's responsibility to enter that portion of the address correctly.
Google also won't predict PO Boxes or apartment numbers. So, if you are using their API for shipping, address cleansing or data governance, you may want one that will validate the building number, autocomplete the unit number and standardize the information.

Depends on the database server. MySQL
doesn't care, its basically the same thing.
Oracle
, DB2
, and other enterprise level database solutions make a distinction. Usually a schema is a collection of tables and a Database is a collection of schemas.
I don't know why that doesn't work, but this one is logically equivalent and it does work:
-(myField:superneat AND -myOtherField:somethingElse)
Maybe it has something to do with defining the same field twice in the query...

As a correction to those suggesting crontab -l | crontab -
: This does not work on every system. For example, I had to add a job to the root crontab on dozens of servers running an old version SUSE (don't ask why). Old SUSEs prepend comment lines to the output of crontab -l
, making crontab -l | crontab -
non-idempotent (Debian recognizes this problem in the crontab manpage and patched its version of Vixie Cron to change the default behaviour of crontab -l
).
To edit crontabs programmatically on systems where crontab -l
adds comments, you can try the following:
EDITOR=cat crontab -e > old_crontab; cat old_crontab new_job | crontab -
EDITOR=cat
tells crontab to use cat
as an editor (not the usual default vi), which doesn't change the file, but instead copies it to stdout. This might still fail if crontab -
expects input in a format different from what crontab -e
outputs. Do not try to replace the final crontab -
with crontab -e
- it will not work.
You can use implode to return your array with a string separator.
$withComma = implode(",", $array);
echo $withComma;

I successfully followed this answer, but since entitlements have changed, I simply removed the --entitlements "Payload/Application.app/Entitlements.plist"
part of the second to last statement, and it worked like a charm.
Because char
is by default signed
declared that means the range of the variable is
-127 to +127>
your value is overflowed. To get the desired value you have to declared the unsigned
modifier. the modifier's (unsigned
) range is:
0 to 255
to get the the range of any data type follow the process 2^bit
example char
is 8 bit length to get its range just 2 ^(power) 8
.
what version of sonar are you using? There is one option called "sonar.skippedModules=yourmodulename".
This will skip the whole module. So be aware of it.
if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:
If x and/or y is 2-dimensional, then the corresponding columns will be plotted.
In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:
np.squeez doc: Remove single-dimensional entries from the shape of an array.
import numpy as np
import matplotlib.pyplot as plt
data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()
But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:
the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.
Just about every RegEx I've seen - including some used by Microsoft will not allow the following valid email to get through : [email protected]
Just had a real customer with an email address in this format who couldn't place an order.
Here's what I settled on:
MailAddress
constructor with some additional checks (see below):.cmo
or .gmial.com
and asking for confirmation Are you sure this is your correct email address. It looks like there may be a mistake.
Allow the user to accept what they typed if they are sure. try
{
var email = new MailAddress(str);
if (email.Host.EndsWith(".cmo"))
{
return EmailValidation.PossibleTypo;
}
if (!email.Host.EndsWith(".") && email.Host.Contains("."))
{
return EmailValidation.OK;
}
}
catch
{
return EmailValidation.Invalid;
}
There is no function to append the data in dictionary. You just assign the value against new key in existing dictionary. it will automatically add value to the dictionary.
var param = ["Name":"Aloha","user" : "Aloha 2"]
param["questions"] = "Are you mine?"
print(param)
The output will be like
["Name":"Aloha","user" : "Aloha 2","questions" : ""Are you mine"?"]
In Laravel 6 you can get it like this:

The following code uses both data.table
and fastmatch
for increased speed.
library("data.table")
library("fastmatch")
a1 <- setDT(data.frame(a = 1:5, b=letters[1:5]))
a2 <- setDT(data.frame(a = 1:3, b=letters[1:3]))
compare_rows <- a1$a %fin% a2$a
# the %fin% function comes from the `fastmatch` package
added_rows <- a1[which(compare_rows == FALSE)]
added_rows
# a b
# 1: 4 d
# 2: 5 e

Charles Bailey's answer is correct. The exact wording from the C++ standard is (§4.7/4): "If the source type is bool, the value false is converted to zero and the value true is converted to one."
Edit: I see he's added the reference as well -- I'll delete this shortly, if I don't get distracted and forget...
Edit2: Then again, it is probably worth noting that while the Boolean values themselves always convert to zero or one, a number of functions (especially from the C standard library) return values that are "basically Boolean", but represented as int
s that are normally only required to be zero to indicate false or non-zero to indicate true. For example, the is* functions in <ctype.h>
only require zero or non-zero, not necessarily zero or one.
If you cast that to bool
, zero will convert to false, and non-zero to true (as you'd expect).
based on @LindseyD answer I created a simple BAT file, that opens cygwin in current directory, it may be useful (for me it is). Assuming that You have cygwin's bin directory in PATH.

You can access Globals
entity from any point of your App via Angular dependency injection. If you want to output Globals.role
value in some component's template, you should inject Globals
through the component's constructor like any service:
// hello.component.ts
import { Component } from '@angular/core';
import { Globals } from './globals';
@Component({
selector: 'hello',
template: 'The global role is {{globals.role}}',
providers: [ Globals ] // this depends on situation, see below
})
export class HelloComponent {
constructor(public globals: Globals) {}
}
I provided Globals
in the HelloComponent
, but instead it could be provided in some HelloComponent's
parent component or even in AppModule
. It will not matter until your Globals
has only static data that could not be changed (say, constants only). But if it's not true and for example different components/services might want to change that data, then the Globals
must be a singleton. In that case it should be provided in the topmost level of the hierarchy where it is going to be used. Let's say this is AppModule
:
import { Globals } from './globals'
@NgModule({
// ... imports, declarations etc
providers: [
// ... other global providers
Globals // so do not provide it into another components/services if you want it to be a singleton
]
})
Also, it's impossible to use var the way you did, it should be
// globals.ts
import { Injectable } from '@angular/core';
@Injectable()
export class Globals {
role: string = 'test';
}
Update
At last, I created a simple demo on stackblitz, where single Globals
is being shared between 3 components and one of them can change the value of Globals.role
.
In most regex dialects there are a set of convenient character summaries you can use for this kind of thing - these are good ones to remember:
\w
- Matches any word character.
\W
- Matches any nonword character.
\s
- Matches any white-space character.
\S
- Matches anything but white-space characters.
\d
- Matches any digit.
\D
- Matches anything except digits.
A search for "Regex Cheatsheets" should reward you with a whole lot of useful summaries.
What is the code of your button? If it's an a tag, then you could do this:
a {_x000D_
padding: 5px;_x000D_
background: green;_x000D_
}_x000D_
a:visited {_x000D_
background: red;_x000D_
}
_x000D_
<a href="#">A button</a>
_x000D_
Or you could use jQuery to add a class on click, as below:
$("#button").click(function() {_x000D_
$("#button").addClass('button-clicked');_x000D_
});
_x000D_
.button-clicked {_x000D_
background: red;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button id="button">Button</button>
_x000D_
No. The best you can do is to use a border-bottom
with a different color, but that isn't really underlining.
You can use pandas.DataFrame.fillna
with the method='ffill'
option. 'ffill'
stands for 'forward fill' and will propagate last valid observation forward. The alternative is 'bfill'
which works the same way, but backwards.
import pandas as pd
df = pd.DataFrame([[1, 2, 3], [4, None, None], [None, None, 9]])
df = df.fillna(method='ffill')
print(df)
# 0 1 2
#0 1 2 3
#1 4 2 3
#2 4 2 9
There is also a direct synonym function for this, pandas.DataFrame.ffill
, to make things simpler.
INSERT
syntax cannot have WHERE
but you can use UPDATE
.
The syntax is as follows:
UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;
Extending to Matt D and others answers, the command can be till Apache Hadoop 3.0.0
hadoop fs -du [-s] [-h] [-v] [-x] URI [URI ...]
It displays sizes of files and directories contained in the given directory or the length of a file in case it's just a file.
Options:
- The -s option will result in an aggregate summary of file lengths being displayed, rather than the individual files. Without the -s option, the calculation is done by going 1-level deep from the given path.
- The -h option will format file sizes in a human-readable fashion (e.g 64.0m instead of 67108864)
- The -v option will display the names of columns as a header line.
- The -x option will exclude snapshots from the result calculation. Without the -x option (default), the result is always calculated from all INodes, including all snapshots under the given path.
du
returns three columns with the following format: +-------------------------------------------------------------------+
| size | disk_space_consumed_with_all_replicas | full_path_name |
+-------------------------------------------------------------------+
##Example command:
hadoop fs -du /user/hadoop/dir1 \
/user/hadoop/file1 \
hdfs://nn.example.com/user/hadoop/dir1
Exit Code: Returns 0 on success and -1 on error.
Here is a simple method to plot two histograms, with their bars side-by-side, on the same plot when the data has different sizes:
def plotHistogram(p, o):
"""
p and o are iterables with the values you want to
plot the histogram of
"""
plt.hist([p, o], color=['g','r'], alpha=0.8, bins=50)
plt.show()
This looks like a Json array list.Therefore its best to use ArrayList
to handle the data. In your api end point add array list like this
@GET("places/")
Call<ArrayList<Place>> getNearbyPlaces(@Query("latitude") String latitude, @Query("longitude") String longitude);
There is no standard Unix command, AFAIK. I haven't used Sun OS, but on Linux, you can use this:
cat /proc/cpuinfo
Sorry that it is Linux, not Sun OS. There is probably something similar though for Sun OS.
Something like this would work
/^\d{2}$/
This will work:
WebElement searchbox = driver.findElement(By.name("j_username"));
WebElement searchbox2 = driver.findElement(By.name("j_password"));
try {
FileInputStream file = new FileInputStream(new File("C:\\paulo.xls"));
HSSFWorkbook workbook = new HSSFWorkbook(file);
HSSFSheet sheet = workbook.getSheetAt(0);
for (int i=1; i <= sheet.getLastRowNum(); i++){
HSSFCell j_username = sheet.getRow(i).getCell(0)
HSSFCell j_password = sheet.getRow(i).getCell(0)
//Setting the Cell type as String
j_username.setCellType(j_username.CELL_TYPE_STRING)
j_password.setCellType(j_password.CELL_TYPE_STRING)
searchbox.sendKeys(j_username.toString());
searchbox2.sendKeys(j_password.toString());
searchbox.submit();
driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);
}
workbook.close();
file.close();
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
}
None of the answers, including the checked one did not work for me.
The solution was far more simple. I first removed the references from my BUS layer. Then deleted the dll's from the project (to make sure it's gone), then reinstalled JSON.NET from nuget packeges. And, the tricky part was, "turning it off and on again".
I just restarted visual studio, and there it worked!
So, if you try everything possible and still can't solve the problem, just try turning visual studio off and on again, it might help.
In my case I had an issue around using Microsoft.ReportViewer.WebForms. I removed validate=true from add verb
line in web.config and it started working:
<system.web>
<httpHandlers>
<add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
You can do the following:
Load the data:
test <- read.csv(
"http://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/breast-cancer-wisconsin.data",
header=FALSE)
Note that the default value of the header
argument for read.csv
is TRUE
so in order to get all lines you need to set it to FALSE
.
Add names to the different columns in the data.frame
names(test) <- c("A","B","C","D","E","F","G","H","I","J","K")
or alternative and faster as I understand (not reloading the entire dataset):
colnames(test) <- c("A","B","C","D","E","F","G","H","I","J","K")
If the values are integer then you can use [2-3]
or you can use [5,7,8]
for non continuous values.
#!/bin/bash
while [ $# -gt 0 ];
do
case $1 in
1)
echo "one"
;;
[2-3])
echo "two or three"
;;
[4-6])
echo "four to six"
;;
[7,9])
echo "seven or nine"
;;
*)
echo "others"
;;
esac
shift
done
If the values are string then you can use |
.
#!/bin/bash
while [ $# -gt 0 ];
do
case $1 in
"one")
echo "one"
;;
"two" | "three")
echo "two or three"
;;
*)
echo "others"
;;
esac
shift
done
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
You can sort like this:
Collections.sort(studlist, new Comparator<Student>() {
@Override
public int compare(Student o1, Student o2) {
return o1.getStud_location().compareTo(o2.getStud_location());
}
});
Assuming you also have the getter for location on your Student class.
Create a repository folder under your project. Let's take
${project.basedir}/src/main/resources/repo
Then, install your custom jar to this repo:
mvn install:install-file -Dfile=[FILE_PATH] \
-DgroupId=[GROUP] -DartifactId=[ARTIFACT] -Dversion=[VERS] \
-Dpackaging=jar -DlocalRepositoryPath=[REPO_DIR]
Lastly, add the following repo and dependency definitions to the projects pom.xml:
<repositories>
<repository>
<id>project-repo</id>
<url>file://${project.basedir}/src/main/resources/repo</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>[GROUP]</groupId>
<artifactId>[ARTIFACT]</artifactId>
<version>[VERS]</version>
</dependency>
</dependencies>
In case of password reset, it is recommended to reset it through sending password reset token to registered user email and ask user to provide new password.

Windows 7 64-bit, with both Python3.4 and Python2.7 installed at some point :)
I'm using Py.exe to route to Py2 or Py3 depending on the script's needs - but I previously improperly uninstalled Python27 before.
Py27 was removed manually from C:\python\Python27 (the folder Python27 was deleted by me previously)
Upon re-installing Python27, it gave the above error you specify.
It would always back out while trying to 'remove shortcuts' during the installation process.
I placed a copy of Python27 back in that original folder, at C:\Python\Python27, and re-ran the same failing Python27 installer. It was happy locating those items and removing them, and proceeded with the install.
This is not the answer that addresses registry key issues (others mention that) but it is somewhat of a workaround if you know of previous installations that were improperly removed.
You could have some insight to this by opening "regedit" and searching for "Python27" - a registry key appeared in my command-shell Cache pointing at c:\python\python27\ (which had been removed and was not present when searching in the registry upon finding it).
That may help point to previously improperly removed installations.
Good luck!
List<string> keyList = new List<string>(this.yourDictionary.Keys);
There is no direct format specifier for this in the C language. Although I wrote this quick python snippet to help you understand the process step by step to roll your own.
#!/usr/bin/python
dec = input("Enter a decimal number to convert: ")
base = 2
solution = ""
while dec >= base:
solution = str(dec%base) + solution
dec = dec/base
if dec > 0:
solution = str(dec) + solution
print solution
Explained:
dec = input("Enter a decimal number to convert: ") - prompt the user for numerical input (there are multiple ways to do this in C via scanf for example)
base = 2 - specify our base is 2 (binary)
solution = "" - create an empty string in which we will concatenate our solution
while dec >= base: - while our number is bigger than the base entered
solution = str(dec%base) + solution - get the modulus of the number to the base, and add it to the beginning of our string (we must add numbers right to left using division and remainder method). the str() function converts the result of the operation to a string. You cannot concatenate integers with strings in python without a type conversion.
dec = dec/base - divide the decimal number by the base in preperation to take the next modulo
if dec > 0: solution = str(dec) + solution - if anything is left over, add it to the beginning (this will be 1, if anything)
print solution - print the final number

I think it would be much easier to put an anchor
tag around i
. You can just use the css :hover
selector. Less moving parts makes maintenance easier, and less javascript to load makes the page quicker.
This will do the trick:
<style>
a.icon-link:hover {
background-color: pink;
}
</style>
<a href="#" class="icon-link" id="course-0"><i class="icon-thumbsup"></id></a>
This is how you save the relevant file as a Excel12 (.xlsx) file... It is not as you would intuitively think i.e. using Excel.XlFileFormat.xlExcel12
but Excel.XlFileFormat.xlOpenXMLWorkbook
. The actual C# command was
excelWorkbook.SaveAs(strFullFilePathNoExt, Excel.XlFileFormat.xlOpenXMLWorkbook, Missing.Value,
Missing.Value, false, false, Excel.XlSaveAsAccessMode.xlNoChange,
Excel.XlSaveConflictResolution.xlUserResolution, true,
Missing.Value, Missing.Value, Missing.Value);
I hope this helps someone else in the future.
Missing.Value
is found in the System.Reflection
namespace.
This code works for me:
public void Run()
{
Dog myDog = new Dog();
myDog.Name= "Foo";
myDog.Color = DogColor.Brown;
System.Console.WriteLine("{0}", myDog.ToString());
MemoryStream stream = SerializeToStream(myDog);
Dog newDog = (Dog)DeserializeFromStream(stream);
System.Console.WriteLine("{0}", newDog.ToString());
}
Where the types are like this:
[Serializable]
public enum DogColor
{
Brown,
Black,
Mottled
}
[Serializable]
public class Dog
{
public String Name
{
get; set;
}
public DogColor Color
{
get;set;
}
public override String ToString()
{
return String.Format("Dog: {0}/{1}", Name, Color);
}
}
and the utility methods are:
public static MemoryStream SerializeToStream(object o)
{
MemoryStream stream = new MemoryStream();
IFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, o);
return stream;
}
public static object DeserializeFromStream(MemoryStream stream)
{
IFormatter formatter = new BinaryFormatter();
stream.Seek(0, SeekOrigin.Begin);
object o = formatter.Deserialize(stream);
return o;
}
Taking in account some answers read here I'd like to propose this:
function getSelectorFromElement($el) {
if (!$el || !$el.length) {
return ;
}
function _getChildSelector(index) {
if (typeof index === 'undefined') {
return '';
}
index = index + 1;
return ':nth-child(' + index + ')';
}
function _getIdAndClassNames($el) {
var selector = '';
// attach id if exists
var elId = $el.attr('id');
if(elId){
selector += '#' + elId;
}
// attach class names if exists
var classNames = $el.attr('class');
if(classNames){
selector += '.' + classNames.replace(/^\s+|\s+$/g, '').replace(/\s/gi, '.');
}
return selector;
}
// get all parents siblings index and element's tag name,
// except html and body elements
var selector = $el.parents(':not(html,body)')
.map(function() {
var parentIndex = $(this).index();
return this.tagName + _getChildSelector(parentIndex);
})
.get()
.reverse()
.join(' ');
if (selector) {
// get node name from the element itself
selector += ' ' + $el[0].nodeName +
// get child selector from element ifself
_getChildSelector($el.index());
}
selector += _getIdAndClassNames($el);
return selector;
}
Maybe useful to create a jQuery plugin?
You somehow have to refer to the variable you want to print the name of. So it would look like:
print varname(something_else)
There is no such function, but if there were it would be kind of pointless. You have to type out something_else
, so you can as well just type quotes to the left and right of it to print the name as a string:
print "something_else"
The simple way to make bold headers:
$row = 1;
foreach($tittles as $index => $tittle) {
$worksheet->getStyleByColumnAndRow($index + 1, $row)->getFont()->setBold(true);
$worksheet->setCellValueByColumnAndRow($index + 1, $row, $tittle);
}
As replace()
creates/returns a new string rather than modifying the original (tt
), you need to set the variable (tt
) equal to the new string returned from the replace
function.
tt = tt.replace(/,/g, '.')
Every answer is rather convoluted. Here:
var url = window.location.href.split('?')[0];
Even if a ? isn't present, it'll still return the first argument, which will be your full URL, minus query string.
It's also protocol-agnostic, meaning you could even use it for things like ftp, itunes.etc.
Rather than trying to address the resource as a File just ask the ClassLoader to return an InputStream for the resource instead via getResourceAsStream:
InputStream in = getClass().getResourceAsStream("/file.txt");
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
As long as the file.txt
resource is available on the classpath then this approach will work the same way regardless of whether the file.txt
resource is in a classes/
directory or inside a jar
.
The URI is not hierarchical
occurs because the URI for a resource within a jar file is going to look something like this: file:/example.jar!/file.txt
. You cannot read the entries within a jar
(a zip
file) like it was a plain old File.
This is explained well by the answers to:
Using copy_if
:
#include <string>
#include <iostream>
#include <algorithm>
int main() {
std::string s1 = "a1a2b3c4a5";
char s2[256];
std::copy_if(s1.begin(), s1.end(), s2, [](char c){return c!='a';});
std::cout << s2 << std::endl;
return 0;
}
When you have opened a folder in a workspace you can do Ctrl+P (Cmd+P on Mac) and start typing the filename, or extension to filter the list of filenames
if you have:
You can type css
and press enter and it will open the page.css
. If you type .ts
the list is filtered and contains two items.
You can use .is(':visible')
Selects all elements that are visible.
For example:
if($('#selectDiv').is(':visible')){
Also, you can get the div which is visible by:
$('div:visible').callYourFunction();
Live example:
console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));
_x000D_
#selectDiv {_x000D_
display: none; _x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>
_x000D_
Is it possible to use a
.netrc
file on Windows?
Yes: You must:
%HOME%
(pre-Git 2.0, no longer needed with Git 2.0+)_netrc
file in %HOME%
If you are using Windows 7/10, in a CMD
session, type:
setx HOME %USERPROFILE%
and the %HOME%
will be set to 'C:\Users\"username"
'.
Go that that folder (cd %HOME%
) and make a file called '_netrc
'
Note: Again, for Windows, you need a '_netrc
' file, not a '.netrc
' file.
Its content is quite standard (Replace the <examples>
with your values):
machine <hostname1>
login <login1>
password <password1>
machine <hostname2>
login <login2>
password <password2>
Luke mentions in the comments:
Using the latest version of msysgit on Windows 7, I did not need to set the
HOME
environment variable. The_netrc
file alone did the trick.
This is indeed what I mentioned in "Trying to “install
” github, .ssh
dir not there":
git-cmd.bat
included in msysgit does set the %HOME%
environment variable:
@if not exist "%HOME%" @set HOME=%HOMEDRIVE%%HOMEPATH%
@if not exist "%HOME%" @set HOME=%USERPROFILE%
??? believes in the comments that "it seems that it won't work for http protocol"
However, I answered that netrc
is used by curl
, and works for HTTP protocol, as shown in this example (look for 'netrc
' in the page): . Also used with HTTP protocol here: "_netrc
/.netrc
alternative to cURL
".
A common trap with with netrc
support on Windows is that git will bypass using it if an origin https url specifies a user name.
For example, if your .git/config
file contains:
[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = https://[email protected]/p/my-project/
Git will not resolve your credentials via _netrc
, to fix this remove your username, like so:
[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = https://code.google.com/p/my-project/
Alternative solution: With git version 1.7.9+ (January 2012): This answer from Mark Longair details the credential cache mechanism which also allows you to not store your password in plain text as shown below.
With Git 1.8.3 (April 2013):
You now can use an encrypted .netrc (with gpg
).
On Windows: %HOME%/_netrc
(_
, not '.
')
A new read-only credential helper (in
contrib/
) to interact with the.netrc/.authinfo
files has been added.
That script would allow you to use gpg-encrypted netrc files, avoiding the issue of having your credentials stored in a plain text file.
Files with the
.gpg
extension will be decrypted by GPG before parsing.
Multiple-f
arguments are OK. They are processed in order, and the first matching entry found is returned via the credential helper protocol.When no
-f
option is given,.authinfo.gpg
,.netrc.gpg
,.authinfo
, and.netrc
files in your home directory are used in this order.
To enable this credential helper:
git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'
(Note that Git will prepend "
git-credential-
" to the helper name and look for it in the path.)
# and if you want lots of debugging info:
git config credential.helper '$shortname -f AUTHFILE -d'
#or to see the files opened and data found:
git config credential.helper '$shortname -f AUTHFILE -v'
See a full example at "Is there a way to skip password typing when using https:// github
"
With Git 2.18+ (June 2018), you now can customize the GPG program used to decrypt the encrypted .netrc
file.
See commit 786ef50, commit f07eeed (12 May 2018) by Luis Marsano (``).
(Merged by Junio C Hamano -- gitster
-- in commit 017b7c5, 30 May 2018)
git-credential-netrc
: acceptgpg
option
git-credential-netrc
was hardcoded to decrypt with 'gpg
' regardless of the gpg.program option.
This is a problem on distributions like Debian that call modern GnuPG something else, like 'gpg2
'
I'll share a code which has Basic Auth Header form data request body,
let username = 'test-name';
let password = 'EbQZB37gbS2yEsfs';
let formdata = new FormData();
let headers = new Headers();
formdata.append('grant_type','password');
formdata.append('username','testname');
formdata.append('password','qawsedrf');
headers.append('Authorization', 'Basic ' + base64.encode(username + ":" + password));
fetch('https://www.example.com/token.php', {
method: 'POST',
headers: headers,
body: formdata
}).then((response) => response.json())
.then((responseJson) => {
console.log(responseJson);
this.setState({
data: responseJson
})
})
.catch((error) => {
console.error(error);
});
For Python users the pattern to use with t3chbot's excellent answer looks like:
https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-python/vsextensions/python/{version_number}/vspackage
be sure to scroll right to see where you have to enter the version number.
The only cure I know for this is a good editor. Sorry.
Something like:
function populate(selector) {
$(selector)
.append('<option value="foo">foo</option>')
.append('<option value="bar">bar</option>')
}
populate('#myform .myselect');
Or even:
$.fn.populate = function() {
$(this)
.append('<option value="foo">foo</option>')
.append('<option value="bar">bar</option>')
}
$('#myform .myselect').populate();
On Debian we use the start-stop-daemon
utility, which handles pid-files, changing the user, putting the daemon into background and much more.
I'm not familiar with RedHat, but the daemon
utility that you are already using (which is defined in /etc/init.d/functions
, btw.) is mentioned everywhere as the equivalent to start-stop-daemon
, so either it can also change the uid of your program, or the way you do it is already the correct one.
If you look around the net, there are several ready-made wrappers that you can use. Some may even be already packaged in RedHat. Have a look at daemonize
, for example.
Try:
itemsCard.ToList().Select(c=>c.Price).Sum();
Actually this would perform better:
var itemsInCart = from o in db.OrderLineItems
where o.OrderId == currentOrder.OrderId
select new { o.WishListItem.Price };
var sum = itemsCard.ToList().Select(c=>c.Price).Sum();
Because you'll only be retrieving one column from the database.
as a workaround you can use the stdin device in /dev directory
....| for item in `cat /dev/stdin` ; do echo $item ;done
according the documentation, this should do it...
RESET QUERY CACHE
The answer above didn't work for me, what did eventually was this syntax:
curl https://${URL} &> /dev/stdout | tee -a ${LOG}
tee puts the output on the screen, but also appends it to my log.
I want to add to Michael Berkowski's answer that this can also happen if the array's order is reversed, in which case it's a bit trickier to observe the issue, because in the json object, the order will be ordered ascending.
For example:
[
3 => 'a',
2 => 'b',
1 => 'c',
0 => 'd'
]
Will return:
{
0: 'd',
1: 'c',
2: 'b',
3: 'a'
}
So the solution in this case, is to use array_reverse
before encoding it to json
Now, in Django 1.9 you have first()
method for querysets.
YourModel.objects.all().first()
This is a better way than .get()
or [0]
because it does not throw an exception if queryset is empty, Therafore, you don't need to check using exists()
This is my favorite use of 112 and 114
select (convert(varchar, getdate(), 112)+ replace(convert(varchar, getdate(), 114),':','')) as 'Getdate()
112 + 114 or YYYYMMDDHHMMSSMSS'
Result:
Getdate() 112 + 114 or YYYYMMDDHHMMSSMSS
20171016083349100
You cannot do this with an attribute because they are just meta information generated at compile time. Just add code to the constructor to initialize the date if required, create a trigger and handle missing values in the database, or implement the getter in a way that it returns DateTime.Now if the backing field is not initialized.
public DateTime DateCreated
{
get
{
return this.dateCreated.HasValue
? this.dateCreated.Value
: DateTime.Now;
}
set { this.dateCreated = value; }
}
private DateTime? dateCreated = null;
If you do an "Add" it will add it to the bottom of the list. You need to do an "Insert" if you want the item added to the top of the list.
For my case gulp-ignore was perfect. As option you may pass a function there:
function condition(file) {
// do whatever with file.path
// return boolean true if needed to exclude file
}
And the task would look like this:
var gulpIgnore = require('gulp-ignore');
gulp.task('task', function() {
gulp.src('./**/*.js')
.pipe(gulpIgnore.exclude(condition))
.pipe(gulp.dest('./dist/'));
});
Yes, endEditing is the best option. And From iOW 7.0, UIScrollView
has a cool feature to dismiss the keyboard on interacting with the scroll view. For achieving this, you can set keyboardDismissMode
property of UIScrollView
.
Set the keyboard dismiss mode as:
tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag
It has few other types. Have a look at this apple document.
I want to post this link as it may help further for peeps checking this answer and looking for more java style convention
Java Programming Style Guidelines
Item "2.13 is prefix should be used for boolean variables and methods." is specifically relevant and suggests the is prefix.
The style guide goes on to suggest:
There are a few alternatives to the is prefix that fits better in some situations. These are has, can and should prefixes:
boolean hasLicense();
boolean canEvaluate();
boolean shouldAbort = false;
If you follow the Guidelines I believe the appropriate method would be named:
shouldCreateFreshSnapshot()
