The fundamental difference in most programming languages is that unless the unexpected happens a for
loop will always repeat n
times or until a break statement, (which may be conditional), is met then finish with a while
loop it may repeat 0 times, 1, more or even forever
, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while
loop, (or repeat until
), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).
It is worth noting that in Python a for
or while
statement can have break
, continue
and else
statements where:
break
- terminates the loopcontinue
- moves on to the next time around the loop without executing following code this time aroundelse
- is executed if the loop completed without any break
statements being executed.N.B. In the now unsupported Python 2 range
produced a list of integers but you could use xrange
to use an iterator. In Python 3 range
returns an iterator.
So the answer to your question is 'it all depends on what you are trying to do'!
This flexbox principle also works horizontally
During calculations of flex bases and flexible lengths, auto margins
are treated as 0.
Prior to alignment via justify-content and
align-self, any positive free space is distributed to auto margins in
that dimension.
Setting an automatic left margin for the Last Item will do the work.
.last-item {
margin-left: auto;
}
Code Example:
.container {_x000D_
display: flex;_x000D_
width: 400px;_x000D_
outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
height: 50px;_x000D_
width: 50px;_x000D_
margin: 5px;_x000D_
background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
margin-left: auto;_x000D_
}
_x000D_
<div class="container">_x000D_
<p></p>_x000D_
<p></p>_x000D_
<p></p>_x000D_
<p class="last-item"></p>_x000D_
</div>
_x000D_
This can be very useful for Desktop Footers.
As Envato did here with the company logo.
The accepted answer as well as most of the answers (if not all of them) have one common limitation which might not be the case for the owner of the question (they have contiguous data) but for future readers.
For example, consider this very simple scenario:
the accepted solution would give 4
while the correct answer is 6
.
Find the index of first non-empty value starting from the end of the array by using the reverse method.
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Sheet1')
const lrow = sh.getLastRow();
const Avals = sh.getRange("A1:A"+lrow).getValues();
const Alast = lrow - Avals.reverse().findIndex(c=>c[0]!='');
Your query would always return an empty recordset since cut_name= '?????' and cut_name='??'
will never evaluate to true
.
In general, INTERSECT
in MySQL
should be emulated like this:
SELECT *
FROM mytable m
WHERE EXISTS
(
SELECT NULL
FROM othertable o
WHERE (o.col1 = m.col1 OR (m.col1 IS NULL AND o.col1 IS NULL))
AND (o.col2 = m.col2 OR (m.col2 IS NULL AND o.col2 IS NULL))
AND (o.col3 = m.col3 OR (m.col3 IS NULL AND o.col3 IS NULL))
)
If both your tables have columns marked as NOT NULL
, you can omit the IS NULL
parts and rewrite the query with a slightly more efficient IN
:
SELECT *
FROM mytable m
WHERE (col1, col2, col3) IN
(
SELECT col1, col2, col3
FROM othertable o
)
I used starikovs' solution. I started with a bash window and gave the commands
cd ~
touch .bashrc
Then I found the .bashrc file in windows explorer, opened it with notepad++ and added
PATH=$PATH:"C:\Program Files (x86)\Notepad++"
so that bash knows where to find Notepad++. (Having Notepad++ in the bash PATH is a useful thing on its own!) Then I pasted his line
git config --global core.editor "notepad++.exe -multiInst"
into a bash window. I started a new bash window for a git repository to test things with the command
git rebase -i HEAD~10
and the file opened in Notepad++ as hoped.
If you still have files that are supposed to be deleted after re-installing a package, make sure the folder build
is also deleted. Therefore, assuming that pkg
is the package you want to delete:
rm -r $(python3 -c "import pkg; print(pkg.__path__[0] + '*' )")
rm -rf build
Obove work out for python3 and delete the package and its *.egg-info file
And if you have more than two lists to concatenate:
import operator
from functools import reduce # For Python 3
list1, list2, list3 = [1,2,3], ['a','b','c'], [7,8,9]
reduce(operator.add, [list1, list2, list3])
# or with an existing list
all_lists = [list1, list2, list3]
reduce(operator.add, all_lists)
It doesn't actually save you any time (intermediate lists are still created) but nice if you have a variable number of lists to flatten, e.g., *args
.
You can use Pandas:
import pandas as pd
pd.Series(your_array).to_json(orient='values')
You can create a 'comment' table, with an id as primary key, then you add a text field to capture the text inserted by the user and you need another field to link the comment table to the article table (foreign key). Plus you need a field to store the user that has entered a comment, this field can be the user's email. Then you capture via GET or POST the user's email and comment and you insert everything in the DB:
"INSERT INTO comment (comment, email, approved) VALUES ('$comment', '$email', '$approved')"
This is a first hint. Of course adding a comment feature it takes a little bit. Then you should think about a form to let the admin to approve the comments and how to publish the comments in the end of articles.
Just include <stdbool.h>
if your system provides it. That defines a number of macros, including bool
, false
, and true
(defined to _Bool
, 0, and 1 respectively). See section 7.16 of C99 for more details.
Check if "nowrap" solve the issue to an extent. Note: nowrap is not supported in HTML5
<table border="1" style="width: 100%; white-space: nowrap; table-layout: fixed;">
<tr>
<td style="overflow: hidden; text-overflow: ellipsis;" nowrap >This cells has more content </td>
<td style="overflow: hidden; text-overflow: ellipsis;" nowrap >Less content here has more content</td>
</tr>
Most of my XML parsing life is spent extracting nuggets of useful information out of truckloads of XML (Amazon MWS). As such, my answer assumes you want only specific information and you know where it is located.
I find the easiest way to use XMLReader is to know which tags I want the information out of and use them. If you know the structure of the XML and it has lots of unique tags, I find that using the first case is the easy. Cases 2 and 3 are just to show you how it can be done for more complex tags. This is extremely fast; I have a discussion of speed over on What is the fastest XML parser in PHP?
The most important thing to remember when doing tag-based parsing like this is to use if ($myXML->nodeType == XMLReader::ELEMENT) {...
- which checks to be sure we're only dealing with opening nodes and not whitespace or closing nodes or whatever.
function parseMyXML ($xml) { //pass in an XML string
$myXML = new XMLReader();
$myXML->xml($xml);
while ($myXML->read()) { //start reading.
if ($myXML->nodeType == XMLReader::ELEMENT) { //only opening tags.
$tag = $myXML->name; //make $tag contain the name of the tag
switch ($tag) {
case 'Tag1': //this tag contains no child elements, only the content we need. And it's unique.
$variable = $myXML->readInnerXML(); //now variable contains the contents of tag1
break;
case 'Tag2': //this tag contains child elements, of which we only want one.
while($myXML->read()) { //so we tell it to keep reading
if ($myXML->nodeType == XMLReader::ELEMENT && $myXML->name === 'Amount') { // and when it finds the amount tag...
$variable2 = $myXML->readInnerXML(); //...put it in $variable2.
break;
}
}
break;
case 'Tag3': //tag3 also has children, which are not unique, but we need two of the children this time.
while($myXML->read()) {
if ($myXML->nodeType == XMLReader::ELEMENT && $myXML->name === 'Amount') {
$variable3 = $myXML->readInnerXML();
break;
} else if ($myXML->nodeType == XMLReader::ELEMENT && $myXML->name === 'Currency') {
$variable4 = $myXML->readInnerXML();
break;
}
}
break;
}
}
}
$myXML->close();
}
In my case it needed higher permissions along with this memory limit increase.

Different web servers implement different techniques for handling incoming HTTP requests in parallel. A pretty popular technique is using threads -- that is, the web server will create/dedicate a single thread for each incoming request. The Apache HTTP web server supports multiple models for handling requests, one of which (called the worker MPM) uses threads. But it supports another concurrency model called the prefork MPM which uses processes -- that is, the web server will create/dedicate a single process for each request.
There are also other completely different concurrency models (using Asynchronous sockets and I/O), as well as ones that mix two or even three models together. For the purpose of answering this question, we are only concerned with the two models above, and taking Apache HTTP server as an example.
PHP itself does not respond to the actual HTTP requests -- this is the job of the web server. So we configure the web server to forward requests to PHP for processing, then receive the result and send it back to the user. There are multiple ways to chain the web server with PHP. For Apache HTTP Server, the most popular is "mod_php". This module is actually PHP itself, but compiled as a module for the web server, and so it gets loaded right inside it.
There are other methods for chaining PHP with Apache and other web servers, but mod_php is the most popular one and will also serve for answering your question.
You may not have needed to understand these details before, because hosting companies and GNU/Linux distros come with everything prepared for us.
Since with mod_php, PHP gets loaded right into Apache, if Apache is going to handle concurrency using its Worker MPM (that is, using Threads) then PHP must be able to operate within this same multi-threaded environment -- meaning, PHP has to be thread-safe to be able to play ball correctly with Apache!
At this point, you should be thinking "OK, so if I'm using a multi-threaded web server and I'm going to embed PHP right into it, then I must use the thread-safe version of PHP". And this would be correct thinking. However, as it happens, PHP's thread-safety is highly disputed. It's a use-if-you-really-really-know-what-you-are-doing ground.
In case you are wondering, my personal advice would be to not use PHP in a multi-threaded environment if you have the choice!
Speaking only of Unix-based environments, I'd say that fortunately, you only have to think of this if you are going to use PHP with Apache web server, in which case you are advised to go with the prefork MPM of Apache (which doesn't use threads, and therefore, PHP thread-safety doesn't matter) and all GNU/Linux distributions that I know of will take that decision for you when you are installing Apache + PHP through their package system, without even prompting you for a choice. If you are going to use other webservers such as nginx or lighttpd, you won't have the option to embed PHP into them anyway. You will be looking at using FastCGI or something equal which works in a different model where PHP is totally outside of the web server with multiple PHP processes used for answering requests through e.g. FastCGI. For such cases, thread-safety also doesn't matter. To see which version your website is using put a file containing <?php phpinfo(); ?>
on your site and look for the Server API
entry. This could say something like CGI/FastCGI
or Apache 2.0 Handler
.
If you also look at the command-line version of PHP -- thread safety does not matter.
Finally, if thread-safety doesn't matter so which version should you use -- the thread-safe or the non-thread-safe? Frankly, I don't have a scientific answer! But I'd guess that the non-thread-safe version is faster and/or less buggy, or otherwise they would have just offered the thread-safe version and not bothered to give us the choice!
You can use scanf function to read string
scanf("%[^\n]",name);
i don't know about other better options to receive string,
Consolidating all the different approaches here.
Sample table structure is below and will update from Product_BAK to Product table.
CREATE TABLE [dbo].[Product](
[Id] [int] IDENTITY(1, 1) NOT NULL,
[Name] [nvarchar](100) NOT NULL,
[Description] [nvarchar](100) NULL
) ON [PRIMARY]
CREATE TABLE [dbo].[Product_BAK](
[Id] [int] IDENTITY(1, 1) NOT NULL,
[Name] [nvarchar](100) NOT NULL,
[Description] [nvarchar](100) NULL
) ON [PRIMARY]
update P1
set Name = P2.Name
from Product P1
inner join Product_Bak P2 on p1.id = P2.id
where p1.id = 2
; With CTE as
(
select id, name from Product_Bak where id = 2
)
update P
set Name = P2.name
from product P inner join CTE P2 on P.id = P2.id
where P2.id = 2
Merge into product P1
using Product_Bak P2 on P1.id = P2.id
when matched then
update set p1.[description] = p2.[description], p1.name = P2.Name;
In this Merge statement, we can do inset if not finding a matching record in the target, but exist in the source and please find syntax:
Merge into product P1
using Product_Bak P2 on P1.id = P2.id;
when matched then
update set p1.[description] = p2.[description], p1.name = P2.Name;
WHEN NOT MATCHED THEN
insert (name, description)
values(p2.name, P2.description);
<div class="row" style="padding-left:21px;">
<ul class="nav nav-tabs" style="padding-left:40px;">
<li class="active filter"><a href="#month" onclick="Data(this)">This Month</a></li>
<li class="filter"><a href="#year" onclick="Data(this)">Year</a></li>
<li class="filter"><a href="#last60" onclick="Data(this)">60 Days</a></li>
<li class="filter"><a href="#last90" onclick="Data(this)">90 Days</a></li>
</ul>
</div>
<script>
function Data(element)
{
element.removeClass('active');
element.addClass('active') ;
}
</script>
Move the jar files from your classpath to web-inf/lib, and run a new tomcat server.
With C++11 or higher you can use find()
and find_first_of()
Example using find to find a single char:
#include <string>
std::string name = "Aaah";
size_t found_index = name.find('a');
if (found_index != std::string::npos) {
// Found string containing 'a'
}
Example using find to find a full string & starting from position 5:
std::string name = "Aaah";
size_t found_index = name.find('h', 3);
if (found_index != std::string::npos) {
// Found string containing 'h'
}
Example using the find_first_of()
and only the first char, to search at the start only:
std::string name = ".hidden._di.r";
size_t found_index = name.find_first_of('.');
if (found_index == 0) {
// Found '.' at first position in string
}
Good luck!
This worked for me:
File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)
clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.
Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.
then in:
Run >> Edit Configurations
Add this line to VM Options:
--module-path /path/to/JavaFX/lib --add-modules=javafx.controls
(oh and don't forget to set the SDK)
Here is yet another solution using JavaScript. Specialities of my solution:
The tests are based on integers but since date objects in JavaScript are comparable you can just throw in two date objects as well. Or you could throw in the millisecond timestamp.
/**
* Compares to comparable objects to find out whether they overlap.
* It is assumed that the interval is in the format [from,to) (read: from is inclusive, to is exclusive).
* A null value is interpreted as infinity
*/
function intervalsOverlap(from1, to1, from2, to2) {
return (to2 === null || from1 < to2) && (to1 === null || to1 > from2);
}
describe('', function() {
function generateTest(firstRange, secondRange, expected) {
it(JSON.stringify(firstRange) + ' and ' + JSON.stringify(secondRange), function() {
expect(intervalsOverlap(firstRange[0], firstRange[1], secondRange[0], secondRange[1])).toBe(expected);
});
}
describe('no overlap (touching ends)', function() {
generateTest([10,20], [20,30], false);
generateTest([20,30], [10,20], false);
generateTest([10,20], [20,null], false);
generateTest([20,null], [10,20], false);
generateTest([null,20], [20,30], false);
generateTest([20,30], [null,20], false);
});
describe('do overlap (one end overlaps)', function() {
generateTest([10,20], [19,30], true);
generateTest([19,30], [10,20], true);
generateTest([10,20], [null,30], true);
generateTest([10,20], [19,null], true);
generateTest([null,30], [10,20], true);
generateTest([19,null], [10,20], true);
});
describe('do overlap (one range included in other range)', function() {
generateTest([10,40], [20,30], true);
generateTest([20,30], [10,40], true);
generateTest([10,40], [null,null], true);
generateTest([null,null], [10,40], true);
});
describe('do overlap (both ranges equal)', function() {
generateTest([10,20], [10,20], true);
generateTest([null,20], [null,20], true);
generateTest([10,null], [10,null], true);
generateTest([null,null], [null,null], true);
});
});

Actually the guy who asked that question posted his own answer.
"Vimeo seem to want me to make a HTTP request, and extract the thumbnail URL from the XML they return..."
The Vimeo API docs are here: http://vimeo.com/api/docs/simple-api
In short, your app needs to make a GET request to an URL like the following:
http://vimeo.com/api/v2/video/video_id.output
and parse the returned data to get the thumbnail URL that you require, then download the file at that URL.
It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.
My personal feeling when it comes to reading
if(!status) : if not status
if(status == false) : if status is false
if you are not used to !status reading. I see no harm doing as the second way.
if you use "active" instead of status I thing if(!active) is more readable
I am facing the same problem but only in Chrome Canary and searching a solution I've found this post.
one of the next versions of Chrome is going to force all domains ending on .dev (and .foo) to be redirected to HTTPs via a preloaded HTTP Strict Transport Security (HSTS) header.
{ "name": "dev", "include_subdomains": true, "mode": "force-https" },
{ "name": "foo", "include_subdomains": true, "mode": "force-https" },
So, change your domains.
You can also use the Cookies API and do:
browser.cookies.set({
url: 'example.com',
name: 'HelloWorld',
value: 'HelloWorld',
expirationDate: myDate
}
You can also apply multiple transforms using an extra layer of markup e.g.:
<h3 class="rotated-heading">
<span class="scaled-up">Hey!</span>
</h3>
<style type="text/css">
.rotated-heading
{
transform: rotate(10deg);
}
.scaled-up
{
transform: scale(1.5);
}
</style>
This can be really useful when animating elements with transforms using Javascript.
This function will return the IE major version number as an integer, or undefined
if the browser isn't Internet Explorer. This, like all user agent solutions, is suceptible to user agent spoofing (which has been an official feature of IE since version 8).
function getIEVersion() {
var match = navigator.userAgent.match(/(?:MSIE |Trident\/.*; rv:)(\d+)/);
return match ? parseInt(match[1]) : undefined;
}
Defining your private methods in the @implementation
block is ideal for most purposes. Clang will see these within the @implementation
, regardless of declaration order. There is no need to declare them in a class continuation (aka class extension) or named category.
In some cases, you will need to declare the method in the class continuation (e.g. if using the selector between the class continuation and the @implementation
).
static
functions are very good for particularly sensitive or speed critical private methods.
A convention for naming prefixes can help you avoid accidentally overriding private methods (I find the class name as a prefix safe).
Named categories (e.g. @interface MONObject (PrivateStuff)
) are not a particularly good idea because of potential naming collisions when loading. They're really only useful for friend or protected methods (which are very rarely a good choice). To ensure you are warned of incomplete category implementations, you should actually implement it:
@implementation MONObject (PrivateStuff)
...HERE...
@end
Here's a little annotated cheat sheet:
MONObject.h
@interface MONObject : NSObject
// public declaration required for clients' visibility/use.
@property (nonatomic, assign, readwrite) bool publicBool;
// public declaration required for clients' visibility/use.
- (void)publicMethod;
@end
MONObject.m
@interface MONObject ()
@property (nonatomic, assign, readwrite) bool privateBool;
// you can use a convention where the class name prefix is reserved
// for private methods this can reduce accidental overriding:
- (void)MONObject_privateMethod;
@end
// The potentially good thing about functions is that they are truly
// inaccessible; They may not be overridden, accidentally used,
// looked up via the objc runtime, and will often be eliminated from
// backtraces. Unlike methods, they can also be inlined. If unused
// (e.g. diagnostic omitted in release) or every use is inlined,
// they may be removed from the binary:
static void PrivateMethod(MONObject * pObject) {
pObject.privateBool = true;
}
@implementation MONObject
{
bool anIvar;
}
static void AnotherPrivateMethod(MONObject * pObject) {
if (0 == pObject) {
assert(0 && "invalid parameter");
return;
}
// if declared in the @implementation scope, you *could* access the
// private ivars directly (although you should rarely do this):
pObject->anIvar = true;
}
- (void)publicMethod
{
// declared below -- but clang can see its declaration in this
// translation:
[self privateMethod];
}
// no declaration required.
- (void)privateMethod
{
}
- (void)MONObject_privateMethod
{
}
@end
Another approach which may not be obvious: a C++ type can be both very fast and provide a much higher degree of control, while minimizing the number of exported and loaded objc methods.
The other answers are very complete, and you should definitely use them if you're trying to find the last character of a string. But if you're just trying to use a conditional (e.g. is the last character 'g'), you could also do the following:
if (str.endsWith("g")) {
or, strings
if (str.endsWith("bar")) {
Do .libPaths()
, close every R runing, check in the first directory, remove the zoo
package restart R and install
zoo
again. Of course you need to have sufficient rights.
Say you have a superclass Fruit and the subclass Banana and you have a method addBananaToBasket()
The method will not accept grapes for example so you want to make sure that you're adding a banana to the basket.
So:
Fruit myFruit = new Banana();
((Banana)myFruit).addBananaToBasket();
? This is called casting
I had the same problem, and want to let you know that none of the above worked for me. What worked for me was:
Intent dialogIntent = new Intent(this, myActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(dialogIntent);
and in one my subclasses, stored in a separate file I had to:
public static Service myService;
myService = this;
new SubService(myService);
Intent dialogIntent = new Intent(myService, myActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
myService.startActivity(dialogIntent);
All the other answers gave me a nullpointerexception

I just want to explain it in my own way with a small story that I experienced in one of my projects. First I want to explain Why DAO is important? rather than go to What is DAO? for better understanding.
Why DAO is important?
In my one project of my project, I used Client.class
which contains all the basic information of our system users. Where I need client then every time I need to do an ugly query where it is needed. Then I felt that decreases the readability and made a lot of redundant boilerplate code.
Then one of my senior developers introduced a QueryUtils.class
where all queries are added using public static
access modifier and then I don't need to do query everywhere. Suppose when I needed activated clients then I just call -
QueryUtils.findAllActivatedClients();
In this way, I made some optimizations of my code.
But there was another problem !!!
I felt that the QueryUtils.class was growing very highly. 100+ methods were included in that class which was also very cumbersome to read and use. Because this class contains other queries of another domain models ( For example- products, categories locations, etc ).
Then the superhero Mr. CTO introduced a new solution named DAO which solved the problem finally. I felt DAO is very domain-specific. For example, he created a DAO called ClientDAO.class
where all Client.class
related queries are found which seems very easy for me to use and maintain. The giant QueryUtils.class
was broken down into many other domain-specific DAO for example - ProductsDAO.class
, CategoriesDAO.class
, etc which made the code more Readable, more Maintainable, more Decoupled.
What is DAO?
It is an object or interface, which made an easy way to access data from the database without writing complex and ugly queries every time in a reusable way.

@Autowired and @Required are targets property level so bean should register in spring IOC before use these annotations. To enable these annotations either have to register respective beans or include <context:annotation-config />
. i.e. <context:annotation-config />
works with registered beans only.
@Required enables RequiredAnnotationBeanPostProcessor
processing tool
@Autowired enables AutowiredAnnotationBeanPostProcessor
processing tool
Note: Annotation itself nothing to do, we need a Processing Tool, which is a class underneath, responsible for the core process.
@Repository, @Service and @Controller are @Component, and they targets class level.
<context:component-scan>
it scans the package and find and register the beans, and it includes the work done by <context:annotation-config />

As from iOS 13 your app also needs Core Location access in order to use the CNCopyCurrentNetworkInfo
function unless it configured the current network or has VPN configurations:
So this is what you need (see apple documentation):
- Link the CoreLocation.framework
library
- Add location-services
as a UIRequiredDeviceCapabilities
Key/Value in Info.plist
- Add a NSLocationWhenInUseUsageDescription
Key/Value in Info.plist describing why your app requires Core Location
- Add the "Access WiFi Information" entitlement for your app
Now as an Objective-C example, first check if location access has been accepted before reading the network info using CNCopyCurrentNetworkInfo
:
- (void)fetchSSIDInfo {
NSString *ssid = NSLocalizedString(@"not_found", nil);
if (@available(iOS 13.0, *)) {
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {
NSLog(@"User has explicitly denied authorization for this application, or location services are disabled in Settings.");
} else {
CLLocationManager* cllocation = [[CLLocationManager alloc] init];
if(![CLLocationManager locationServicesEnabled] || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined){
[cllocation requestWhenInUseAuthorization];
usleep(500);
return [self fetchSSIDInfo];
}
}
}
NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
id info = nil;
for (NSString *ifnam in ifs) {
info = (__bridge_transfer id)CNCopyCurrentNetworkInfo(
(__bridge CFStringRef)ifnam);
NSDictionary *infoDict = (NSDictionary *)info;
for (NSString *key in infoDict.allKeys) {
if ([key isEqualToString:@"SSID"]) {
ssid = [infoDict objectForKey:key];
}
}
}
...
...
}
In Typescript, one doesn't necessarily have to follow the new instance()
Singleton methodology. An imported, constructor-less static class can work equally as well.
Consider:
export class YourSingleton {
public static foo:bar;
public static initialise(_initVars:any):void {
YourSingleton.foo = _initvars.foo;
}
public static doThing():bar {
return YourSingleton.foo
}
}
You can import the class and refer to YourSingleton.doThing()
in any other class. But remember, because this is a static class, it has no constructor so I usually use an intialise()
method that is called from a class that imports the Singleton:
import {YourSingleton} from 'singleton.ts';
YourSingleton.initialise(params);
let _result:bar = YourSingleton.doThing();
Don't forget that in a static class, every method and variable needs to also be static so instead of this
you would use the full class name YourSingleton
.
For a slightly different take on the question. A scripting language is a programming language but a programming language is not necessarily a scripting language. A scripting language is used to control or script a system. That system could be an operating system where the scripting language would be bash. The system could be a web server with PHP the scripting language. Scripting languages are designed to fill a specific niche; they are domain specific languages. Interactive systems have interpreted scripting languages giving rise to the notion that scripting languages are interpreted; however, this is a consequence of the system and not the scripting language itself.

I would prefer to not use ts-node and always run from dist folder.
To do that, just setup your package.json with default config:
....
"main": "dist/server.js",
"scripts": {
"build": "tsc",
"prestart": "npm run build",
"start": "node .",
"dev": "nodemon"
},
....
and then add nodemon.json config file:
{
"watch": ["src"],
"ext": "ts",
"ignore": ["src/**/*.spec.ts"],
"exec": "npm restart"
}
Here, i use "exec": "npm restart"
so all ts file will re-compile to js file and then restart the server.
To run while in dev environment,
npm run dev
Using this setup I will always run from the distributed files and no need for ts-node.

Missing from the other answers is how to allow localhost(or 0.0.0.0 or whatever) as an oauth callback url. Here is the explanation. How can I add localhost:3000 to Facebook App for development
Like many others, I would suggest implementing a to_dict() function rather than (or in addition to) allowing casting to a dictionary. I think it makes it more obvious that the class supports that kind of functionality. You could easily implement such a method like this:
def to_dict(self):
class_vars = vars(MyClass) # get any "default" attrs defined at the class level
inst_vars = vars(self) # get any attrs defined on the instance (self)
all_vars = dict(class_vars)
all_vars.update(inst_vars)
# filter out private attributes
public_vars = {k: v for k, v in all_vars.items() if not k.startswith('_')}
return public_vars
new String(byteArray, Charset.defaultCharset())
This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.
there is no standard, but most frameworks support both, you can see for example for java spring that it accepts both here
@GetMapping("/api/foos")
@ResponseBody
public String getFoos(@RequestParam List<String> id) {
return "IDs are " + id;
}
And Spring MVC will map a comma-delimited id parameter:
http://localhost:8080/api/foos?id=1,2,3
----
IDs are [1,2,3]
Or a list of separate id parameters:
http://localhost:8080/api/foos?id=1&id=2
----
IDs are [1,2]
class
is a keyword that is used only* to introduce class definitions. When you declare new class instances either as local objects or as function parameters you use only the name of the class (which must be in scope) and not the keyword class
itself.
e.g.
class ANewType
{
// ... details
};
This defines a new type called ANewType
which is a class type.
You can then use this in function declarations:
void function(ANewType object);
You can then pass objects of type ANewType
into the function. The object will be copied into the function parameter so, much like basic types, any attempt to modify the parameter will modify only the parameter in the function and won't affect the object that was originally passed in.
If you want to modify the object outside the function as indicated by the comments in your function body you would need to take the object by reference (or pointer). E.g.
void function(ANewType& object); // object passed by reference
This syntax means that any use of object
in the function body refers to the actual object which was passed into the function and not a copy. All modifications will modify this object and be visible once the function has completed.
[* The class
keyword is also used in template definitions, but that's a different subject.]
(This info is from The Git User's Manual)
I'm also learning, so this might not be exactly an answer to the question but it might help somebody:
git branch -r
)git fetch
. This will not effect any of you existing, custom created branches.git add origin /path/to/repository
) use git checkout origin/branch_name
, this will override your locals changes on branch branch_name
In simple words a static synchronized
method will lock the class instead of the object, and it will lock the class because the keyword static
means: "class instead of instance".
The keyword synchronized
means that only one thread can access the method at a time.
And static synchronized
mean:
Only one thread can access the class at one time.
Another possible solution:
sek=[]
L=[1,2,3,4,5,6,7,8,9,0]
for i in [2, 4, 7, 0, 3]:
a=[L[i]]
sek=sek+a
print (sek)
// Once finished with the bitmap objects, we deallocate them.
originalBMP.Dispose();
bannerBMP.Dispose();
oGraphics.Dispose();
This is a programming style that you'll regret sooner or later. Sooner is knocking on the door, you forgot one. You are not disposing newBitmap. Which keeps a lock on the file until the garbage collector runs. If it doesn't run then the second time you try to save to the same file you'll get the klaboom. GDI+ exceptions are too miserable to give a good diagnostic so serious head-scratching ensues. Beyond the thousands of googlable posts that mention this mistake.
Always favor using the using statement. Which never forgets to dispose an object, even if the code throws an exception.
using (var newBitmap = new Bitmap(thumbBMP)) {
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
}
Albeit that it is very unclear why you even create a new bitmap, saving thumbBMP should already be good enough. Anyhoo, give the rest of your disposable objects the same using love.
I can open the log directly via the iOS simulator: Debug -> Open System Log...
Not sure when this was introduced, so it might not be available for earlier versions.
please do not set id of child class which is generator class is foreign only set parent class id if your parent class id is assigned... just do one thing dont set id of child class via setter method your problem will be fix.....definately.
Just to add here, whenever you get "error: device offline" means that connection with emulator & adb bridge has been broken due to time taken in emulator startup.
Rather than re-starting emulator at this point try below two commands which stops & start adb bridge again.
adb kill-server
adb start-server
If you do not want to specify a message with your stashed changes, pass the filename after a double-dash.
$ git stash -- filename.ext
If it's an untracked/new file, you will have to stage it first.
However, if you do want to specify a message, use push
.
git stash push -m "describe changes to filename.ext" filename.ext
Both methods work in git versions 2.13+

I have had the same problem.
In my case, since I have the original repository in my local machine, I have made a copy in a new folder without any hidden file (.git, .gitignore).
Finally I have added the .gitignore file to the new created folder.
Then I have created and added the new repository from the local path (in my case using GitHub Desktop).
It is pretty easy. If you are using DB generated Ids (like IDENTITY
in MS SQL) you just need to add entity to ObjectSet
and SaveChanges
on related ObjectContext
. Id
will be automatically filled for you:
using (var context = new MyContext())
{
context.MyEntities.Add(myNewObject);
context.SaveChanges();
int id = myNewObject.Id; // Yes it's here
}
Entity framework by default follows each INSERT
with SELECT SCOPE_IDENTITY()
when auto-generated Id
s are used.
You have at least these 3 issues:
display
yet in your javascript you attempt to get element myDiv
which is not even defined in your markup.You can save all three values at once by doing:
var title=new Array();
var names=new Array();//renamed to names -added an S-
//to avoid conflicts with the input named "name"
var tickets=new Array();
function insert(){
var titleValue = document.getElementById('title').value;
var actorValue = document.getElementById('name').value;
var ticketsValue = document.getElementById('tickets').value;
title[title.length]=titleValue;
names[names.length]=actorValue;
tickets[tickets.length]=ticketsValue;
}
And then change the show function to:
function show() {
var content="<b>All Elements of the Arrays :</b><br>";
for(var i = 0; i < title.length; i++) {
content +=title[i]+"<br>";
}
for(var i = 0; i < names.length; i++) {
content +=names[i]+"<br>";
}
for(var i = 0; i < tickets.length; i++) {
content +=tickets[i]+"<br>";
}
document.getElementById('display').innerHTML = content; //note that I changed
//to 'display' because that's
//what you have in your markup
}
Here's a jsfiddle for you to play around.
You could also add an offset if you want to use negative indexes:
uint8_t l_matrix[10][20];
uint8_t (*matrix_ptr)[20] = l_matrix+5;
matrix_ptr[-4][1]=7;
If your compiler gives an error or warning you could use:
uint8_t (*matrix_ptr)[20] = (uint8_t (*)[20]) l_matrix;
Try this:
<div class="row">
<div class="col-md-5">
Set room heater temperature
</div>
<div class="col-md-2"></div>
<div class="col-md-5">
Set room heater temperature
</div>
</div>
You can also use colnames
instead of names if you have data.frame
or matrix
In my case, my JSON object didn't have any existing Array in it, so I had to create array element first and then had to push the element.
elementToPush = [1, 2, 3]
if (!obj.arr) this.$set(obj, "arr", [])
obj.arr.push(elementToPush)
(This answer may not be relevant to this particular question, but may help someone else)
First of all, if you want it displayed on a PHP form, the medium is HTML and so a new line will be rendered with the <br />
tag. Check the source HTML of the page - you may possibly have the new line rendered just as a line break, in which case your problem is simply one of translating the text for output to a web browser.
Try '\1'
for the replacement (single quotes are important, otherwise you need to escape the \
):
"foo".gsub(/(o+)/, '\1\1\1')
#=> "foooooo"
But since you only seem to be interested in the capture group, note that you can index a string with a regex:
"foo"[/oo/]
#=> "oo"
"Z_123: foobar"[/^Z_.*(?=:)/]
#=> "Z_123"

Sign-off is a line at the end of the commit message which certifies who is the author of the commit. Its main purpose is to improve tracking of who did what, especially with patches.
Example commit:
Add tests for the payment processor.
Signed-off-by: Humpty Dumpty <[email protected]>
It should contain the user real name if used for an open-source project.
If branch maintainer need to slightly modify patches in order to merge them, he could ask the submitter to rediff, but it would be counter-productive. He can adjust the code and put his sign-off at the end so the original author still gets credit for the patch.

That will be possible only if the HTML file is also loaded with the file
protocol from the local user's harddisk.
If the HTML page is served by HTTP from a server, you can't access any local files by specifying them in a src
attribute with the file://
protocol as that would mean you could access any file on the users computer without the user knowing which would be a huge security risk.
As Dimitar Bonev said, you can access a file if the user selects it using a file selector on their own. Without that step, it's forbidden by all browsers for good reasons. Thus, while his answer might prove useful for many people, it loosens the requirement from the code in the original question.
The number in parentheses specifies the precision of fractional seconds to be stored. So, (0)
would mean don't store any fraction of a second, and use only whole seconds. The default value if unspecified is 6 digits after the decimal separator.
So an unspecified value would store a date like:
TIMESTAMP 24-JAN-2012 08.00.05.993847 AM
And specifying (0)
stores only:
TIMESTAMP(0) 24-JAN-2012 08.00.05 AM

Check the current role you are logged into by using: SELECT CURRENT_USER, SESSION_USER;
Note: It must match with Owner of the schema.
Schema | Name | Type | Owner
--------+--------+-------+----------
If the owner is different, then give all the grants to the current user role from the admin role by :
GRANT 'ROLE_OWNER' to 'CURRENT ROLENAME';
Then try to execute the query, it will give the output as it has access to all the relations now.

Here is how I encountered this error in Django and fixed it:
urlpatterns = [path('home/', views.home, 'home'),]
urlpatterns = [path('home/', views.home, name='home'),]
Depends on the situation. If it is a special case, then return null. If the function just happens to return an empty collection, then obviously returning that is ok. However, returning an empty collection as a special case because of invalid parameters or other reasons is NOT a good idea, because it is masking a special case condition.
Actually, in this case I usually prefer to throw an exception to make sure it is REALLY not ignored :)
Saying that it makes the code more robust (by returning an empty collection) as they do not have to handle the null condition is bad, as it is simply masking a problem that should be handled by the calling code.
You can run this command for making a factory reset:
killall dropbear uhttpd; sleep 1; mtd -r erase rootfs_data
I had a great deal of trouble with this. I just wanted to:
thisBill.IntervalCount = jPaidCountSpinner.getValue();
Where IntervalCount is a Long, and the JSpinner was set to return a Long. Eventually I had to write this function:
public static final Long getLong(Object obj) throws IllegalArgumentException {
Long rv;
if((obj.getClass() == Integer.class) || (obj.getClass() == Long.class) || (obj.getClass() == Double.class)) {
rv = Long.parseLong(obj.toString());
}
else if((obj.getClass() == int.class) || (obj.getClass() == long.class) || (obj.getClass() == double.class)) {
rv = (Long) obj;
}
else if(obj.getClass() == String.class) {
rv = Long.parseLong(obj.toString());
}
else {
throw new IllegalArgumentException("getLong: type " + obj.getClass() + " = \"" + obj.toString() + "\" unaccounted for");
}
return rv;
}
which seems to do the trick. No amount of simple casting, none of the above solutions worked for me. Very frustrating.

If you want to open command prompt inside your eclipse, this can be a useful approach to link cmd with eclipse.
You can follow this link to get the steps in detail with screenshots. How to use cmd prompt inside Eclipse ?
I'm quoting the steps here:
Step 1: Setup a new External Configuration Tool
In the Eclipse tool go to Run -> External Tools -> External Tools Configurations option.
Step 2: Click New Launch Configuration option in Create, manage and run configuration screen
Step 3: New Configuration screen for configuring the command prompt
Step 4: Provide configuration details of the Command Prompt in the Main tab
Name: Give any name to your configuration (Here it is Command_Prompt)
Location: Location of the CMD.exe in your Windows
Working Directory: Any directory where you want to point the Command prompt
Step 5: Tick the check box Allocate console This will ensure the eclipse console is being used as the command prompt for any input or output.
Step 6: Click Run and you are there!! You will land up in the C: directory as a working directory
Since cP/WHM took away the ability to modify User privileges as root in PHPMyAdmin, you have to use the command line to:
mysql> GRANT FILE ON *.* TO 'user'@'localhost';
Step 2 is to allow that user to dump a file in a specific folder. There are a few ways to do this but I ended up putting a folder in :
/home/user/tmp/db
and
chown mysql:mysql /home/user/tmp/db
That allows the mysql user to write the file. As previous posters have said, you can use the MySQL temp folder too, I don't suppose it really matters but you definitely don't want to make it 0777 permission (world-writeable) unless you want the world to see your data. There is a potential problem if you want to rinse-repeat the process as INTO OUTFILE
won't work if the file exists. If your files are owned by a different user then just trying to unlink($file)
won't work. If you're like me (paranoid about 0777) then you can set your target directory using:
chmod($dir,0777)
just prior to doing the SQL command, then
chmod($dir,0755)
immediately after, followed by unlink(file)
to delete the file. This keeps it all running under your web user and no need to invoke the mysql user.

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles
.modal {
display: block;
}
.modal-body:before,
.modal-body:after {
display: table;
content: " ";
}
.modal-header:before,
.modal-header:after {
display: table;
content: " ";
}
(The last ones are necessary if you use custom directives) and encapsulate the html with
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">

If you set a static height for your header, you can use that in a calculation for the size of your wrapper.
http://jsfiddle.net/ske5Lqyv/5/
Using your example code, you can add this CSS:
html, body {
margin: 0px;
padding: 0px;
height: 100%;
}
#container {
height: 100%;
}
.header {
height: 64px;
background-color: lightblue;
}
.wrapper {
height: calc(100% - 64px);
overflow-y: auto;
}
Or, you can use flexbox for a more dynamic approach http://jsfiddle.net/19zbs7je/3/
<div id="container">
<div class="section">
<div class="header">Heading</div>
<div class="wrapper">

Getting this error, I changed the
c/C++ > Code Generation > Runtime Library to Multi-threaded library (DLL) /MD
for both code project and associated Google Test project. This solved the issue.
Note: all components of the project must have the same definition in c/C++ > Code Generation > Runtime Library. Either DLL or not DLL, but identical.
It is possible to get a web application running in full screen in both iOS and Android, it is called a PWA and after mucha hard work, it was the only way around this issue.
PWAs open a number of interesting options for development that should not be missed. I've made a couple already, check out this Public and Private Tender Manual For Designers (Spanish). And here is an English explanation from the CosmicJS site
Here some basic explanation of hibernate cache...
First level cache is associated with “session” object.
The scope of cache objects is of session. Once session is closed, cached objects are gone forever.
First level cache is enabled by default and you can not disable it.
When we query an entity first time, it is retrieved from database and stored in first level cache associated with hibernate session.
If we query same object again with same session object, it will be loaded from cache and no sql query will be executed.
The loaded entity can be removed from session using evict()
method. The next loading of this entity will again make a database call if it has been removed using evict()
method.
The whole session cache can be removed using clear()
method. It will remove all the entities stored in cache.
Second level cache is apart from first level cache which is available to be used globally in session factory scope.
second level cache is created in session factory scope and is available to be used in all sessions which are created using that particular session factory.
It also means that once session factory is closed, all cache associated with it die and cache manager also closed down.
Whenever hibernate session try to load an entity, the very first place it look for cached copy of entity in first level cache (associated with particular hibernate session).
If cached copy of entity is present in first level cache, it is returned as result of load method.
If there is no cached entity in first level cache, then second level cache is looked up for cached entity.
If second level cache has cached entity, it is returned as result of load method. But, before returning the entity, it is stored in first level cache also so that next invocation to load method for entity will return the entity from first level cache itself, and there will not be need to go to second level cache again.
If entity is not found in first level cache and second level cache also, then database query is executed and entity is stored in both cache levels, before returning as response of load()
method.

This does not work for existing jobs, however there is Jenkins job builder.
This allows one to keep job definitions in yaml files and in a git repo which is very portable.
<?php
$j=1;
array_reverse($skills_nav);
foreach ( $skills_nav as $skill ) {
$a = '<li><a href="#" data-filter=".'.$skill->slug.'">';
$a .= $skill->name;
$a .= '</a></li>';
echo $a;
echo "\n";
$j++;
}
?>
An excellent plug-in is jscrollpane
Use bellow command from CLI interface

The JQuery answer. Since JavaScript was invented in order to develop JQuery, I am giving you an example in JQuery doing this:
<div class="menu">
<a href="http://example.org">Example</a>
<a href="http://foobar.com">Foobar.com</a>
</div>
<script>
jQuery( 'div.menu a' )
.click(function() {
do_the_click( this.href );
return false;
});
// play the funky music white boy
function do_the_click( url )
{
alert( url );
}
</script>
Yep, Use a better option source filter. If you're searching with JSON it'll look something like this:
{
"_source": ["user", "message", ...],
"query": ...,
"size": ...
}
In ES 2.4 and earlier, you could also use the fields option to the search API:
{
"fields": ["user", "message", ...],
"query": ...,
"size": ...
}
This is deprecated in ES 5+. And source filters are more powerful anyway!
Pure CSS Workaround:
I was using both bootstrap and jQuery UI and changing the order of adding the scripts broke some other objects. I ended up using pure CSS workaround:
.ui-dialog-titlebar-close {
background: url("http://code.jquery.com/ui/1.10.3/themes/smoothness/images/ui-icons_888888_256x240.png") repeat scroll -93px -128px rgba(0, 0, 0, 0);
border: medium none;
}
.ui-dialog-titlebar-close:hover {
background: url("http://code.jquery.com/ui/1.10.3/themes/smoothness/images/ui-icons_222222_256x240.png") repeat scroll -93px -128px rgba(0, 0, 0, 0);
}
This is the solution we went with. Simply save the scroll position when the overlay is opened, scroll back to the saved position any time the user attempted to scroll the page, and turn the listener off when the overlay is closed.
It's a bit jumpy on IE, but works like a charm on Firefox/Chrome.

Assuming that you use SimpleDateFormat implicitly or explicitly, you need to use H
instead of h
in the format string.
E.g
HH:mm:ss
instead of
hh:mm:ss
What happens is when these elements are called before the DOM is loaded these kind of errors come up. Always use:
window.onload = function(){
this.keywordsInput.nativeElement.focus();
}
$routeProvider resolve property allows delaying of route change until data is loaded.
First define a route with resolve
attribute like this.
angular.module('phonecat', ['phonecatFilters', 'phonecatServices', 'phonecatDirectives']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: PhoneListCtrl,
resolve: PhoneListCtrl.resolve}).
when('/phones/:phoneId', {
templateUrl: 'partials/phone-detail.html',
controller: PhoneDetailCtrl,
resolve: PhoneDetailCtrl.resolve}).
otherwise({redirectTo: '/phones'});
}]);
notice that the resolve
property is defined on route.
function PhoneListCtrl($scope, phones) {
$scope.phones = phones;
$scope.orderProp = 'age';
}
PhoneListCtrl.resolve = {
phones: function(Phone, $q) {
// see: https://groups.google.com/forum/?fromgroups=#!topic/angular/DGf7yyD4Oc4
var deferred = $q.defer();
Phone.query(function(successData) {
deferred.resolve(successData);
}, function(errorData) {
deferred.reject(); // you could optionally pass error data here
});
return deferred.promise;
},
delay: function($q, $defer) {
var delay = $q.defer();
$defer(delay.resolve, 1000);
return delay.promise;
}
}
Notice that the controller definition contains a resolve object which declares things which should be available to the controller constructor. Here the phones
is injected into the controller and it is defined in the resolve
property.
The resolve.phones
function is responsible for returning a promise. All of the promises are collected and the route change is delayed until after all of the promises are resolved.
Working demo: http://mhevery.github.com/angular-phonecat/app/#/phones Source: https://github.com/mhevery/angular-phonecat/commit/ba33d3ec2d01b70eb5d3d531619bf90153496831
If you want to find the rows that are duplicated you can use find_duplicates
from hablar
:
library(dplyr)
library(hablar)
df <- tibble(a = c(1, 2, 2, 4),
b = c(5, 2, 2, 8))
df %>% find_duplicates()
Try this:
np.concatenate((a, np.array([a[0]])))
http://docs.scipy.org/doc/numpy/reference/generated/numpy.concatenate.html
concatenate needs both elements to be numpy arrays; however, a[0] is not an array. That is why it does not work.
Yes, Java bytecode (and source code) is platform independent, assuming you use platform independent libraries. 32 vs. 64 bit shouldn't matter.
A file object is an instance of Blob but a blob object is not an instance of File
new File([], 'foo.txt').constructor.name === 'File' //true
new File([], 'foo.txt') instanceof File // true
new File([], 'foo.txt') instanceof Blob // true
new Blob([]).constructor.name === 'Blob' //true
new Blob([]) instanceof Blob //true
new Blob([]) instanceof File // false
new File([], 'foo.txt').constructor.name === new Blob([]).constructor.name //false
If you must convert a file object to a blob object, you can create a new Blob object using the array buffer of the file. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
let reader = new FileReader();
reader.onload = function(e) {
let blob = new Blob([new Uint8Array(e.target.result)], {type: file.type });
console.log(blob);
};
reader.readAsArrayBuffer(file);
As pointed by @bgh you can also use the arrayBuffer method of the File object. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
file.arrayBuffer().then((arrayBuffer) => {
let blob = new Blob([new Uint8Array(arrayBuffer)], {type: file.type });
console.log(blob);
});
If your environment supports async/await you can use a one-liner like below
let fileToBlob = async (file) => new Blob([new Uint8Array(await file.arrayBuffer())], {type: file.type });
console.log(await fileToBlob(new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'})));
Here is a snippet that does not need ajQuery and will enable alerts in a disabled iframe (like on codepen)
for (var i = 0; i < document.getElementsByTagName('iframe').length; i++) {
document.getElementsByTagName('iframe')[i].setAttribute('sandbox','allow-modals');
}
Here is a codepen demo working with an alert() after this fix as well: http://codepen.io/nicholasabrams/pen/vNpoBr?editors=001

You should use "readonly
" instead like:
$("input[type='text']").attr("readonly", "true");
Edit: Answer updated to reflect changes in recent versions of NAudio
It's possible using the NAudio open source .NET audio library I have written. It looks for an ACM codec on your PC to do the conversion. The Mp3FileReader supplied with NAudio currently expects to be able to reposition within the source stream (it builds an index of MP3 frames up front), so it is not appropriate for streaming over the network. However, you can still use the MP3Frame
and AcmMp3FrameDecompressor
classes in NAudio to decompress streamed MP3 on the fly.
I have posted an article on my blog explaining how to play back an MP3 stream using NAudio. Essentially you have one thread downloading MP3 frames, decompressing them and storing them in a BufferedWaveProvider
. Another thread then plays back using the BufferedWaveProvider
as an input.

Here's a poor man's Linux/Python/Expect-like example based on this blog post: Upgrading simple shells to fully interactive TTYs. I needed this for old machines where I can't install Expect or add modules to Python.
Code:
(
echo 'scp [email protected]:./install.sh .'
sleep 5
echo 'scp-passwd'
sleep 5
echo 'exit'
) |
python -c 'import pty; pty.spawn("/usr/bin/bash")'
Output:
scp [email protected]:install.sh .
bash-4.2$ scp [email protected]:install.sh .

There is no float: center; in css. Use margin: 0 auto; instead. So like this:
.mydivclass {
margin: 0 auto;
}
Go to Files->Options->Formulas-> Calculation Options / Set Workbook calculation to Automatic
You can use numpy's slicing, simply start:stop:step
.
>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])
This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2] # O(1), constant time
>>> b[:] = 0 # modifying the view changes original array
>>> a # original array is modified
array([0, 2, 0, 4, 0])
so if either of the above things are a problem, you can make a copy explicitly:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy() # explicit copy, O(n)
>>> b[:] = 0 # modifying the copy
>>> a # original is intact
array([1, 2, 3, 4, 5])
This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.
For completeness:
Along the lines of Chase's answer, I usually use as.data.frame
to coerce the matrix to a data.frame:
m <- as.data.frame(matrix(0, ncol = 30, nrow = 2))
EDIT: speed test data.frame
vs. as.data.frame
system.time(replicate(10000, data.frame(matrix(0, ncol = 30, nrow = 2))))
user system elapsed
8.005 0.108 8.165
system.time(replicate(10000, as.data.frame(matrix(0, ncol = 30, nrow = 2))))
user system elapsed
3.759 0.048 3.802
Yes, it appears to be faster (by about 2 times).

Sources that helped me get to work with my self signed certificate on my AWS Apache server and connect with HttpsURLConnection from android device:
SSL on aws instance - amazon tutorial on ssl
Android Security with HTTPS and SSL - creating your own trust manager on client for accepting your certificate
Creating self signed certificate - easy script for creating your certificates
Then I did the following:
create_my_certs.sh
:#!/bin/bash FQDN=$1 # make directories to work from mkdir -p server/ client/ all/ # Create your very own Root Certificate Authority openssl genrsa \ -out all/my-private-root-ca.privkey.pem \ 2048 # Self-sign your Root Certificate Authority # Since this is private, the details can be as bogus as you like openssl req \ -x509 \ -new \ -nodes \ -key all/my-private-root-ca.privkey.pem \ -days 1024 \ -out all/my-private-root-ca.cert.pem \ -subj "/C=US/ST=Utah/L=Provo/O=ACME Signing Authority Inc/CN=example.com" # Create a Device Certificate for each domain, # such as example.com, *.example.com, awesome.example.com # NOTE: You MUST match CN to the domain name or ip address you want to use openssl genrsa \ -out all/privkey.pem \ 2048 # Create a request from your Device, which your Root CA will sign openssl req -new \ -key all/privkey.pem \ -out all/csr.pem \ -subj "/C=US/ST=Utah/L=Provo/O=ACME Tech Inc/CN=${FQDN}" # Sign the request from Device with your Root CA openssl x509 \ -req -in all/csr.pem \ -CA all/my-private-root-ca.cert.pem \ -CAkey all/my-private-root-ca.privkey.pem \ -CAcreateserial \ -out all/cert.pem \ -days 500 # Put things in their proper place rsync -a all/{privkey,cert}.pem server/ cat all/cert.pem > server/fullchain.pem # we have no intermediates in this case rsync -a all/my-private-root-ca.cert.pem server/ rsync -a all/my-private-root-ca.cert.pem client/
bash create_my_certs.sh yourdomain.com
Place the certificates in their proper place on the server (you can find configuration in /etc/httpd/conf.d/ssl.conf). All these should be set:
SSLCertificateFile
SSLCertificateKeyFile
SSLCertificateChainFile
SSLCACertificateFile
Restart httpd using sudo service httpd restart
and make sure httpd started:
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
Copy my-private-root-ca.cert
to your android project assets folder
Create your trust manager:
SSLContext SSLContext;
CertificateFactory cf = CertificateFactory.getInstance("X.509"); InputStream caInput = context.getAssets().open("my-private-root-ca.cert.pem"); Certificate ca; try { ca = cf.generateCertificate(caInput); } finally { caInput.close(); }
// Create a KeyStore containing our trusted CAs
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);
// Create a TrustManager that trusts the CAs in our KeyStore
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
// Create an SSLContext that uses our TrustManager
SSLContext = SSLContext.getInstance("TLS");
SSSLContext.init(null, tmf.getTrustManagers(), null);
And make the connection using HttpsURLConnection:
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection(); connection.setSSLSocketFactory(SSLContext.getSocketFactory());
Thats it, try your https connection.
This worked for me and I think is more HTML5 compliant. You should change your html to use 'data-' prefix
<div data-example-directive data-number="99"></div>
And within the directive read the variable's value:
scope: {
number : "=",
....
},
You could avoid memory allocation. There are many variants, all having problems in case of multithreading environment.
I prefer this kind of implementation (actually, it is not correctly said I prefer, because I avoid singletons as much as possible):
class Singleton
{
private:
Singleton();
public:
static Singleton& instance()
{
static Singleton INSTANCE;
return INSTANCE;
}
};
It has no dynamic memory allocation.
If you want to reset bootstrap page with button click using jQuery :
function resetForm(){
var validator = $( "#form_ID" ).validate();
validator.resetForm();
}
Using above code you also have change the field colour as red to normal.
If you want to reset only fielded value then :
$("#form_ID")[0].reset();
None of the above solutions worked for me, in a YAML file within a Jekyll project. After trying many options, I realized that an HTML injection with <br>
might do as well, since in the end everything is rendered to HTML:
name: |
In a village of La Mancha <br>
whose name I don't <br>
want to remember.
At least it works for me. No idea on the problems associated to this approach.

If you still want to show the item but make it not clickable and look disabled with CSS:
CSS:
.disabled {
pointer-events:none; //This makes it not clickable
opacity:0.6; //This grays it out to look disabled
}
HTML:
<li class="disabled">Disabled List Item</li>
Also, if you are using BootStrap, they already have a class called disabled for this purpose. See this example.
As @LV98 pointed out, users could change this on the client side and submit a selection you weren't expecting. You will want to validate at the server as well.
You needed to do it like this:

Hope it helped.
Suspend the process with CTRL+Z then use the command bg
to resume it in background. For example:
sleep 60
^Z #Suspend character shown after hitting CTRL+Z
[1]+ Stopped sleep 60 #Message showing stopped process info
bg #Resume current job (last job stopped)
More about job control and bg
usage in bash
manual page:
JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.
EDIT
To start a process where you can even kill the terminal and it still carries on running
nohup [command] [-args] > [filename] 2>&1 &
e.g.
nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &
To just ignore the output (not very wise) change the filename to /dev/null
To get the error message set to a different file change the &1
to a filename.
In addition: You can use the jobs
command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1
or kill %2
with the number being the index of the process.
Your example code is wrong. This works:
import datetime
datetime.datetime.strptime("21/12/2008", "%d/%m/%Y").strftime("%Y-%m-%d")
The call to strptime() parses the first argument according to the format specified in the second, so those two need to match. Then you can call strftime() to format the result into the desired final format.
Use the beginning and end anchors.
Regex regex = new Regex(@"^\d$");
Use "^\d+$"
if you need to match more than one digit.
Note that "\d"
will match [0-9]
and other digit characters like the Eastern Arabic numerals ??????????
. Use "^[0-9]+$"
to restrict matches to just the Arabic numerals 0 - 9.
If you need to include any numeric representations other than just digits (like decimal values for starters), then see @tchrist's comprehensive guide to parsing numbers with regular expressions.
Here's a simple one that worked for me. It checks whether the path exists, and if it doesn't, it will create not only the root path, but all sub-directories also:
$rptpath = "C:\temp\reports\exchange"
if (!(test-path -path $rptpath)) {new-item -path $rptpath -itemtype directory}
As of lodash 3.5.0 you can use sortByOrder (renamed orderBy in v4.3.0):
var data = _.sortByOrder(array_of_objects, ['type','name'], [true, false]);
Since version 3.10.0 you can even use standard semantics for ordering (asc, desc):
var data = _.sortByOrder(array_of_objects, ['type','name'], ['asc', 'desc']);
In version 4 of lodash this method has been renamed orderBy:
var data = _.orderBy(array_of_objects, ['type','name'], ['asc', 'desc']);
You could use LINQ:
var checkedButton = container.Controls.OfType<RadioButton>()
.FirstOrDefault(r => r.Checked);
Note that this requires that all of the radio buttons be directly in the same container (eg, Panel or Form), and that there is only one group in the container. If that is not the case, you could make List<RadioButton>
s in your constructor for each group, then write list.FirstOrDefault(r => r.Checked)
.
Recursion is your friend. I updated the function to account for property arrays:
function getObject(theObject) {
var result = null;
if(theObject instanceof Array) {
for(var i = 0; i < theObject.length; i++) {
result = getObject(theObject[i]);
if (result) {
break;
}
}
}
else
{
for(var prop in theObject) {
console.log(prop + ': ' + theObject[prop]);
if(prop == 'id') {
if(theObject[prop] == 1) {
return theObject;
}
}
if(theObject[prop] instanceof Object || theObject[prop] instanceof Array) {
result = getObject(theObject[prop]);
if (result) {
break;
}
}
}
}
return result;
}

Provided you use the Angular-CLI to generate new projects, there's another way to make bootstrap accessible in Angular 2/4.
$ npm install --save bootstrap
. The --save
option will make bootstrap appear in the dependencies."styles"
array. The reference has to be the relative path to the bootstrap file downloaded with npm. In my case it's: "../node_modules/bootstrap/dist/css/bootstrap.min.css",
My example .angular-cli.json:
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"project": {
"name": "bootstrap-test"
},
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": [
"assets",
"favicon.ico"
],
"index": "index.html",
"main": "main.ts",
"polyfills": "polyfills.ts",
"test": "test.ts",
"tsconfig": "tsconfig.app.json",
"testTsconfig": "tsconfig.spec.json",
"prefix": "app",
"styles": [
"../node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.css"
],
"scripts": [],
"environmentSource": "environments/environment.ts",
"environments": {
"dev": "environments/environment.ts",
"prod": "environments/environment.prod.ts"
}
}
],
"e2e": {
"protractor": {
"config": "./protractor.conf.js"
}
},
"lint": [
{
"project": "src/tsconfig.app.json"
},
{
"project": "src/tsconfig.spec.json"
},
{
"project": "e2e/tsconfig.e2e.json"
}
],
"test": {
"karma": {
"config": "./karma.conf.js"
}
},
"defaults": {
"styleExt": "css",
"component": {}
}
}
Now bootstrap should be part of your default settings.
When I publish apps I use the following screenshot sizes:
Phone: 1080 x 1920 I prepare 8 images with title, some fancy background and a screenshot inside a smartphone mockup. So it's more than a simple screenshot. It gives some nice branding and helps you to stand out from other apps out there.
Tablet 7": 1200 x 1920 - I do actually a couple of raw screenshots of 7" emulator so that the user could know how the layout will appear on his device. No fancy design with titles etc.
Tablet 10": 1800 x 2560 - same thing here, just a couple of raw screenshots.
all in .png
format.
Hope this helps.
Big difference, TABLOCK
will try to grab "shared" locks, and TABLOCKX
exclusive locks.
If you are in a transaction and you grab an exclusive lock on a table, EG:
SELECT 1 FROM TABLE WITH (TABLOCKX)
No other processes will be able to grab any locks on the table, meaning all queries attempting to talk to the table will be blocked until the transaction commits.
TABLOCK
only grabs a shared lock, shared locks are released after a statement is executed if your transaction isolation is READ COMMITTED
(default). If your isolation level is higher, for example: SERIALIZABLE
, shared locks are held until the end of a transaction.
Shared locks are, hmmm, shared. Meaning 2 transactions can both read data from the table at the same time if they both hold a S or IS lock on the table (via TABLOCK
). However, if transaction A
holds a shared lock on a table, transaction B
will not be able to grab an exclusive lock until all shared locks are released. Read about which locks are compatible with which at msdn.
Both hints cause the db to bypass taking more granular locks (like row or page level locks). In principle, more granular locks allow you better concurrency. So for example, one transaction could be updating row 100 in your table and another row 1000, at the same time from two transactions (it gets tricky with page locks, but lets skip that).
In general granular locks is what you want, but sometimes you may want to reduce db concurrency to increase performance of a particular operation and eliminate the chance of deadlocks.
In general you would not use TABLOCK
or TABLOCKX
unless you absolutely needed it for some edge case.
As stated in an article by Slicehost:
User setup
So let's start by adding the main user to the Apache user group:
sudo usermod -a -G www-data demo
That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.
You will need to log out and log back in again to enable the group change.
Check the groups now:
groups ... # demo www-data
So now I am a member of two groups: My own (demo) and the Apache group (www-data).
Folder setup
Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).
Let's set that up:
sudo chgrp -R www-data /home/demo/public_html
As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.
If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.
Setgid
Good so far, but remember the command we just gave only affects existing folders. What about anything new?
We can set the ownership so anything new is also in the 'www-data' group.
The first command will change the permissions for the public_html directory to include the "setgid" bit:
sudo chmod 2750 /home/demo/public_html
That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.
If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:
sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads
The permissions only need to be set once as new files will automatically be assigned the correct ownership.
I had a similar issue on Mac OS and I was able to fix it this way:
From the terminal, run:
mysql -u root -p -h 127.0.0.1 -P 3306
Then, I was asked to enter the password. I just pressed enter since no password was setup.
I got a message as follows:
Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 181. Server version: 8.0.11 Homebrew.
If you succeeded to log into mysql>, run the following command:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
You should get a message like this:
Query OK, 0 rows affected (0.19 sec)
Now, your password is "password" and your username is "root".
Happy coding :)
In my case, boolean values in my Python dict were the problem. JSON boolean values are in lowercase ("true", "false") whereas in Python they are in Uppercase ("True", "False"). Couldn't find this solution anywhere online but hope it helps.
If you want to mock a fake response, another way to do it is to simply instantiate an instance of the base HttpResponse class, like so:
from django.http.response import HttpResponseBase
self.fake_response = HttpResponseBase()
awk 'NR>1{print buf}{buf = $0}'
Essentially, this code says the following:
For each line after the first, print the buffered line
for each line, reset the buffer
The buffer is lagged by one line, hence you end up printing lines 1 to n-1
In order to go to a previous commit version of the file, get the commit number, say eb917a1 then
git checkout eb917a1 YourFileName
If you just need to go back to the last commited version
git reset HEAD YourFileName
git checkout YourFileName
This will simply take you to the last committed state of the file
Yes, 4,2 means "4 digits total, 2 of which are after the decimal place". That translates to a number in the format of 00.00
. Beyond that, you'll have to show us your SQL query. PHP won't translate 3.80 into 99.99 without good reason. Perhaps you've misaligned your fields/values in the query and are trying to insert a larger number that belongs in another field.
This question has been answered, but maybe this might someone else coming here.
I also had an issue where this
is undefined, when I was foolishly trying to destructure the methods of a class when initialising it:
import MyClass from "./myClass"
// 'this' is not defined here:
const { aMethod } = new MyClass()
aMethod() // error: 'this' is not defined
// So instead, init as you would normally:
const myClass = new MyClass()
myClass.aMethod() // OK
if your options have a value, you can do this:
$('select').val("the-value-of-the-option-you-want-to-select");
'select' would be the id of your select or a class selector. or if there is just one select, you can use the tag as it is in the example.
This will work
UIImage *buttonImage = [UIImage imageNamed:@"imageName.png"];
[btn setImage:buttonImage forState:UIControlStateNormal];
[self.view addSubview:btn];
Just invoke ruby XXXXX.rb
in terminal, if the interpreter is in your $PATH variable.
( this can hardly be a rails thing, until you have it running. )
jQuery('#modal_ajax').modal('show', {backdrop: 'static', keyboard: false});
Use CSS position: absolute;
followed by top: 0px; left 0px;
in the style
attribute of each DIV. Replace the pixel values with whatever you want.
You can use z-index: x;
to set the vertical "order" (which one is "on top"). Replace x
with a number, higher numbers are on top of lower numbers.
Here is how your new code would look:
<div>
<div id="backdrop" style="z-index: 1; position: absolute; top: 0px; left: 0px;"><img alt="" src='/backdrop.png' /></div>
<div id="curtain" style="z-index: 2; position: absolute; top: 0px; left: 0px; background-image:url(/curtain.png);background-position:100px 200px; height:250px; width:500px;"> </div>
</div>
<a href="https://www." style="color: inherit;"target="_blank">
For CSS inline style, this worked best for me.
If you've downloaded SQL from the Microsoft site, rename the file to a zip file and then you can extract the files inside to a folder, then choose that one when you "Browse for SQL server Installation Media"
SQLEXPRADV_x64_ENU.exe > SQLEXPRADV_x64_ENU.zip
7zip will open it (standard Windows zip doesn't work though)
Extract to something like C:\SQLInstallMedia
You will get folders like 1033_enu_lp, resources, x64 and a bunch of files.
Look at this example:
public void RunWorker()
{
Thread newThread = new Thread(WorkerMethod);
newThread.Start(new Parameter());
}
public void WorkerMethod(object parameterObj)
{
var parameter = (Parameter)parameterObj;
// do your job!
}
You are first creating a thread by passing delegate to worker method and then starts it with a Thread.Start method which takes your object as parameter.
So in your case you should use it like this:
Thread thread = new Thread(download);
thread.Start(filename);
But your 'download' method still needs to take object, not string as a parameter. You can cast it to string in your method body.
I used docker-entrypoint-initdb.d approach (Thanks to @Kuhess) But in my case I want to create my DB based on some parameters I defined in .env file so I did these
1) First I define .env file something like this in my docker root project directory
MYSQL_DATABASE=my_db_name
MYSQL_USER=user_test
MYSQL_PASSWORD=test
MYSQL_ROOT_PASSWORD=test
MYSQL_PORT=3306
2) Then I define my docker-compose.yml file. So I used the args directive to define my environment variables and I set them from .env file
version: '2'
services:
### MySQL Container
mysql:
build:
context: ./mysql
args:
- MYSQL_DATABASE=${MYSQL_DATABASE}
- MYSQL_USER=${MYSQL_USER}
- MYSQL_PASSWORD=${MYSQL_PASSWORD}
- MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
ports:
- "${MYSQL_PORT}:3306"
3) Then I define a mysql folder that includes a Dockerfile. So the Dockerfile is this
FROM mysql:5.7
RUN chown -R mysql:root /var/lib/mysql/
ARG MYSQL_DATABASE
ARG MYSQL_USER
ARG MYSQL_PASSWORD
ARG MYSQL_ROOT_PASSWORD
ENV MYSQL_DATABASE=$MYSQL_DATABASE
ENV MYSQL_USER=$MYSQL_USER
ENV MYSQL_PASSWORD=$MYSQL_PASSWORD
ENV MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD
ADD data.sql /etc/mysql/data.sql
RUN sed -i 's/MYSQL_DATABASE/'$MYSQL_DATABASE'/g' /etc/mysql/data.sql
RUN cp /etc/mysql/data.sql /docker-entrypoint-initdb.d
EXPOSE 3306
4) Now I use mysqldump to dump my db and put the data.sql inside mysql folder
mysqldump -h <server name> -u<user> -p <db name> > data.sql
The file is just a normal sql dump file but I add 2 lines at the beginning so the file would look like this
--
-- Create a database using `MYSQL_DATABASE` placeholder
--
CREATE DATABASE IF NOT EXISTS `MYSQL_DATABASE`;
USE `MYSQL_DATABASE`;
-- Rest of queries
DROP TABLE IF EXISTS `x`;
CREATE TABLE `x` (..)
LOCK TABLES `x` WRITE;
INSERT INTO `x` VALUES ...;
...
...
...
So what happening is that I used "RUN sed -i 's/MYSQL_DATABASE/'$MYSQL_DATABASE'/g' /etc/mysql/data.sql" command to replace the MYSQL_DATABASE
placeholder with the name of my DB that I have set it in .env file.
|- docker-compose.yml
|- .env
|- mysql
|- Dockerfile
|- data.sql
Now you are ready to build and run your container
How about this one?
"my test string \t\t with crazy stuff is cool ".replace(/\s{2,9999}|\t/g, ' ')
outputs "my test string with crazy stuff is cool "
This one gets rid of any tabs as well
The linear
timing function will animate the defined properties linearly. For the background-image it seems to have this fade/resize effect while changing the frames of you animation (not sure if it is standard behavior, I would go with @Chukie B's approach).
If you use the steps
function, it will animate discretely. See the timing function documentation on MDN for more detail. For you case, do like this:
-webkit-animation-timing-function: steps(1,end);
animation-timing-function: steps(1,end);
See this jsFiddle.
I'm not sure if it is standard behavior either, but when you say that there will be only one step, it allows you to change the starting point in the @keyframes
section. This way you can define each frame of you animation.
There should not be a space after name
.
Incorrect:
{% url 'author' name = p.article_author.name.username %}
Correct:
{% url 'author' name=p.article_author.name.username %}
To append to an array, just use the +=
operator.
$Target += $TargetObject
Also, you need to declare $Target = @()
before your loop because otherwise, it will empty the array every loop.
add 0.5 before casting (if x > 0) or subtract 0.5 (if x < 0), because the compiler will always truncate.
float x = 55; // stored as 54.999999...
x = x + 0.5 - (x<0); // x is now 55.499999...
int y = (int)x; // truncated to 55
C++11 also introduces std::round, which likely uses a similar logic of adding 0.5 to |x| under the hood (see the link if interested) but is obviously more robust.
A follow up question might be why the float isn't stored as exactly 55. For an explanation, see this stackoverflow answer.
This is a variation on hexacyanide's answer above. This middleware also handles the 'data' event but does not wait for the data to be consumed before calling 'next'. This way both this middleware and bodyParser may coexist, consuming the stream in parallel.
app.use(function(req, res, next) {
req.rawBody = '';
req.setEncoding('utf8');
req.on('data', function(chunk) {
req.rawBody += chunk;
});
next();
});
app.use(express.bodyParser());

After show table, above the table ( +options ) Hyperlink is there.
use the following command to install the specific version. say you want to install angular/cli version 1.6.8 then enter the following command :
sudo npm install -g @angular/[email protected]
this will install angular/cli version 1.6.8
You can always tell EF to do this with conventions in the Context class in the OnModelCreating function as follows:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
// <... other configurations ...>
// modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
// modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
// modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
// Configure Decimal to always have a precision of 18 and a scale of 4
modelBuilder.Conventions.Remove<DecimalPropertyConvention>();
modelBuilder.Conventions.Add(new DecimalPropertyConvention(18, 4));
base.OnModelCreating(modelBuilder);
}
This only applies to Code First EF fyi and applies to all decimal types mapped to the db.
With:
FILES = $(shell ls)
indented underneath all
like that, it's a build command. So this expands $(shell ls)
, then tries to run the command FILES ...
.
If FILES
is supposed to be a make
variable, these variables need to be assigned outside the recipe portion, e.g.:
FILES = $(shell ls)
all:
echo $(FILES)
Of course, that means that FILES
will be set to "output from ls
" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ...
to avoid this, for efficiency and/or correctness.1)
If FILES
is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:
all:
FILES="$(shell ls)"
However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:
FILES="$(shell ls)"; echo $$FILES
This is all a bit silly since the shell will expand *
(and other shell glob expressions) for you in the first place, so you can just:
echo *
as your shell command.
Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls
is not completely reliable (some details depend on file names and sometimes even the version of ls
; some versions of ls
attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard)
and $(subst ...)
to accomplish everything inside make
itself (avoiding any "weird characters in file name" issues). (In sh
scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0
to avoid tripping over blanks, newlines, control characters, and so on.)
1The GNU Make documentation notes further that POSIX make added ::=
assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make
variants support ::=
assignment, although GNU make does today, with the same meaning as :=
, i.e., do the assignment right now with expansion.
Note that VAR := $(shell command args...)
can also be spelled VAR != command args...
in several make
variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell)
so using VAR != command args...
is superior in both being shorter and working in more variants.
% ps -o args -C nginx
COMMAND
build/sbin/nginx -c ../test.conf
If nginx was run without the -c
option, then you can use the -V
option to find out the configure arguments that were set to non-standard values. Among them the most interesting for you are:
--prefix=PATH set installation prefix
--sbin-path=PATH set nginx binary pathname
--conf-path=PATH set nginx.conf pathname
My scenario:
eg.
a.button { background-image: url(this.png; }
I found that applying the mark-up provided by Dan Tello didn't work.
However, by placing a span within the anchor element, and setting the background-image to that element I was able to achieve a good result using Dan Tello's markup.
eg.
a.button span { background-image: url(this.png; }
You might want to check you spaces and tabs. A tab is a default of 4 spaces. However, your "if" and "elif" match, so I am not quite sure why. Go into Options in the top bar, and click "Configure IDLE". Check the Indentation Width on the right in Fonts/Tabs, and make sure your indents have that many spaces.
{{ wpis.entry.lastChangeDate|date:"SHORT_DATETIME_FORMAT" }}
First, eq is for comparing strings; == is for comparing numbers.
Even if the "if" condition is satisfied, it doesn't evaluate the "then" block.
I think your problem is that your variables don't contain what you think they do. I think your $str1
or $str2
contains something like "taste\n" or so. Check them by printing before your if: print "str1='$str1'\n";
.
The trailing newline can be removed with the chomp($str1);
function.
Despite all the great answers above and due to me being new to Django, I was still stuck. Here's my explanation from a very newbie perspective.
models.py
class Author(models.Model):
name = models.CharField(max_length=255)
class Book(models.Model):
author = models.ForeignKey(Author)
title = models.CharField(max_length=255)
admin.py (Incorrect Way) - you think it would work by using 'model__field' to reference, but it doesn't
class BookAdmin(admin.ModelAdmin):
model = Book
list_display = ['title', 'author__name', ]
admin.site.register(Book, BookAdmin)
admin.py (Correct Way) - this is how you reference a foreign key name the Django way
class BookAdmin(admin.ModelAdmin):
model = Book
list_display = ['title', 'get_name', ]
def get_name(self, obj):
return obj.author.name
get_name.admin_order_field = 'author' #Allows column order sorting
get_name.short_description = 'Author Name' #Renames column head
#Filtering on side - for some reason, this works
#list_filter = ['title', 'author__name']
admin.site.register(Book, BookAdmin)
For additional reference, see the Django model link here
c# 7.0 lets you do this:
var tupleList = new List<(int, string)>
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
If you don't need a List
, but just an array, you can do:
var tupleList = new(int, string)[]
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
And if you don't like "Item1" and "Item2", you can do:
var tupleList = new List<(int Index, string Name)>
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
or for an array:
var tupleList = new (int Index, string Name)[]
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
which lets you do: tupleList[0].Index
and tupleList[0].Name
Framework 4.6.2 and below
You must install System.ValueTuple
from the Nuget Package Manager.
Framework 4.7 and above
It is built into the framework. Do not install System.ValueTuple
. In fact, remove it and delete it from the bin directory.
note: In real life, I wouldn't be able to choose between cow, chickens or airplane. I would be really torn.
This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.
There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.
The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like
1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host
EDIT
Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication
So, I'm not sure why there's so much consternation on this topic. I can name a git stash
with both a push
and the deprecated save
, and I can use a regex to pull it back with an apply
:
$ git stash push -m "john-hancock"
$ git stash apply stash^{/john-hancock}
As it has been mentioned before, the save
command is deprecated, but it still works, so you can used this on older systems where you can't update them with a push
call. Unlike the push
command, the -m
switch isn't required with save
.
// save is deprecated but still functional
$ git stash save john-hancock
This is Git 2.2 and Windows 10.
Here's a beautiful animated GIF demonstrating the process.
The GIF runs quickly, but if you look, the process is this:
ls
command shows 4 files in the directorytouch example.html
adds a 5th filegit stash push -m "john-hancock" -a
(The -a
includes untracked files)ls
command shows 4 files after the stash, meaning the stash and the implicit hard reset workedgit stash apply stash^{/john-hancock}
runsls
command lists 5 files, showing the example.html file was brought back, meaning the git stash apply
command worked.To be frank, I'm not sure what the benefit of this approach is though. There's value in giving the stash a name, but not the retrieval. Maybe to script the shelve and unshelve process it'd be helpful, but it's still way easier to just pop a stash by name.
$ git stash pop 3
$ git stash apply 3
That looks way easier to me than the regex.
The git interaction library part of StGit is actually pretty good. However, it isn't broken out as a separate package but if there is sufficient interest, I'm sure that can be fixed.
It has very nice abstractions for representing commits, trees etc, and for creating new commits and trees.
window_handles
should give you the references to all open windows.
this is what the docu has to say about switching windows.
NSNotificationCenter add observer syntax in Swift 4.0 for iOS 11
NotificationCenter.default.addObserver(self, selector: #selector(keyboardShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
This is for keyboardWillShow notification name type. Other type can be selected from the available option
the Selector is of type @objc func which handle how the keyboard will show ( this is your user function )
I've also had trouble using any type of javascript "scrollTo" function in an iframe on an iPad. Finally found an "old" solution to the problem, just hash to an anchor.
In my situation after an ajax return my error messages were set to display at the top of the iframe but if the user had scrolled down in what is an admittedly long form the submission goes out and the error appears "above the fold". Additionally, assuming the user did scroll way down the top level page was scrolled away from 0,0 and was also hidden.
I added
<a name="ptop"></a>
to the top of my iframe document and
<a name="atop"></a>
to the top of my top level page
then
$(document).ready(function(){
$("form").bind("ajax:complete",
function() {
location.hash = "#";
top.location.hash = "#";
setTimeout('location.hash="#ptop"',150);
setTimeout('top.location.hash="#atop"',350);
}
)
});
in the iframe.
You have to hash the iframe before the top page or only the iframe will scroll and the top will remain hidden but while it's a tiny bit "jumpy" due to the timeout intervals it works. I imagine tags throughout would allow various "scrollTo" points.
@FindBy(xpath = "//span[@class='y2' and contains(text(), 'Your Text')] ")
private WebElementFacade emailLinkToVerifyAccount;
This approach will work for you, hopefully.
findViewById<Button>(R.id.signUp)?.setOnClickListener(
Toast.makeText(mActivity, "Button Clicked", Toast.LENGTH_LONG).show()
)
With jquery you can do it like:
$('img').click(function(){
$('#foo').css('background-color', 'red').css('color', 'white');
});
this applies for all img
tags you should set an id
attribute for it like image
and then:
$('#image').click(function(){
$('#foo').css('background-color', 'red').css('color', 'white');
});
Don't use array_values
on your $row
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
array_push($res_arr_values, $row);
}
Also, the preferred way to add a value to an array is writing $array[] = $value;
, not using array_push
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$res_arr_values[] = $row;
}
And a further optimization is not to call mysql_fetch_array($result, MYSQL_ASSOC)
but to use mysql_fetch_assoc($result)
directly.
$res_arr_values = array();
while ($row = mysql_fetch_assoc($result))
{
$res_arr_values[] = $row;
}
There were 8 other signals they came up with first.
Based on the first sentence of the question: "I'm trying to write out a Byte[] array representing a complete file to a file."
The path of least resistance would be:
File.WriteAllBytes(string path, byte[] bytes)
Documented here:
class Program
{
static void Main(string[] args)
{
Thread t = new Thread(new ParameterizedThreadStart(ThreadMethod));
t.Start("My Parameter");
}
static void ThreadMethod(object parameter)
{
// parameter equals to "My Parameter"
}
}
There is a small change to happen, it will not come under rowdatabound, first all the rows should get bound, only then could we hide that. So it will be a separate method after the grid is dataBound.
Make sure to balance the risk that fresh statistics cause undesirable changes to query plans against the risk that stale statistics can themselves cause query plans to change.
Imagine you have a bug database with a table ISSUE and a column CREATE_DATE where the values in the column increase more or less monotonically. Now, assume that there is a histogram on this column that tells Oracle that the values for this column are uniformly distributed between January 1, 2008 and September 17, 2008. This makes it possible for the optimizer to reasonably estimate the number of rows that would be returned if you were looking for all issues created last week (i.e. September 7 - 13). If the application continues to be used and the statistics are never updated, though, this histogram will be less and less accurate. So the optimizer will expect queries for "issues created last week" to be less and less accurate over time and may eventually cause Oracle to change the query plan negatively.
You can use the getGraphics method of the component on which you would like to draw. This in turn should allow you to draw lines and make other things which are available through the Graphics class
The accepted answer works well. Just for completeness (and since I like it's shortness), I wanted to share how to to it with compass (SCSS/SASS):
body{
$colorStart: rgba(0,0,0,0);
$colorEnd: rgba(0,0,0,0.8);
@include background-image(linear-gradient(to bottom, $colorStart, $colorEnd), url("bg.jpg"));
}
