SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String date = df.format(Calendar.getInstance().getTime());
Short and effective:
DateFormat.getDateTimeInstance().format(new Date(myMillisValue))
Actually, you're best off with the TextClock widget. It handles all of the complexity for you and will respect the user's 12/24hr preferences. http://developer.android.com/reference/android/widget/TextClock.html
Well, I don't understand why are you used transaction in case when you make a select
.
Transaction is useful when you make changes (add, edit or delete) data from database.
Remove transaction unless you use insert
, update
or delete
statements
Use these Kotlin extensions:
/**
* Converts Pixel to DP.
*/
val Int.pxToDp: Int
get() = (this / Resources.getSystem().displayMetrics.density).toInt()
/**
* Converts DP to Pixel.
*/
val Int.dpToPx: Int
get() = (this * Resources.getSystem().displayMetrics.density).toInt()
This works with multiple popovers and I also added a little big of extra JS to handle the z-index issues that happen with overlapping popovers:
http://jsfiddle.net/erik1337/fvE22/
JavaScript:
var $elements = $('.my-popover');
$elements.each(function () {
var $element = $(this);
$element.popover({
html: true,
placement: 'top',
container: $('body'), // This is just so the btn-group doesn't get messed up... also makes sorting the z-index issue easier
content: $('#content').html()
});
$element.on('shown.bs.popover', function (e) {
var popover = $element.data('bs.popover');
if (typeof popover !== "undefined") {
var $tip = popover.tip();
zindex = $tip.css('z-index');
$tip.find('.close').bind('click', function () {
popover.hide();
});
$tip.mouseover(function (e) {
$tip.css('z-index', function () {
return zindex + 1;
});
})
.mouseout(function () {
$tip.css('z-index', function () {
return zindex;
});
});
}
});
});
HTML:

}
/* Popover styles */
.popover .close {

If you need your script to be portable and you would rather not have any 3rd party dependencies, this is how you send POST request purely in Python 3.
from urllib.parse import urlencode
from urllib.request import Request, urlopen
url = 'https://httpbin.org/post' # Set destination URL here
post_fields = {'foo': 'bar'} # Set POST fields here
request = Request(url, urlencode(post_fields).encode())
json = urlopen(request).read().decode()
print(json)
Sample output:
{
"args": {},
"data": "",
"files": {},
"form": {
"foo": "bar"
},
"headers": {
"Accept-Encoding": "identity",
"Content-Length": "7",
"Content-Type": "application/x-www-form-urlencoded",
"Host": "httpbin.org",
"User-Agent": "Python-urllib/3.3"
},
"json": null,
"origin": "127.0.0.1",
"url": "https://httpbin.org/post"
}
__init_subclass__
As other answer mentioned you can check the __subclasses__
attribute to get the list of subclasses, since python 3.6 you can modify this attribute creation by overriding the __init_subclass__
method.
class PluginBase:
subclasses = []
def __init_subclass__(cls, **kwargs):
super().__init_subclass__(**kwargs)
cls.subclasses.append(cls)
class Plugin1(PluginBase):
pass
class Plugin2(PluginBase):
pass
This way, if you know what you're doing, you can override the behavior of of __subclasses__
and omit/add subclasses from this list.
I think this solution easy one

You have to add the order direction right after the column name:
$qb->orderBy('column1 ASC, column2 DESC');
As you have noted, multiple calls to orderBy
do not stack, but you can make multiple calls to addOrderBy
:
$qb->addOrderBy('column1', 'ASC')
->addOrderBy('column2', 'DESC');
The difference is not just for Chrome but for most of the web browsers.
F5
refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.
Shift + F5
forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.
Shift + F5
guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5
.
You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?
Regarding your query of
So when should interface with default methods be used and when should an abstract class be used? Are the abstract classes still useful in that scenario?
java documentation provides perfect answer.
Abstract Classes Compared to Interfaces:
Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation.
However, with abstract classes, you can declare fields that are not static and final, and define public, protected, and private concrete methods.
With interfaces, all fields are automatically public, static, and final, and all methods that you declare or define (as default methods) are public. In addition, you can extend only one class, whether or not it is abstract, whereas you can implement any number of interfaces.
Use cases for each of them have been explained in below SE post:
What is the difference between an interface and abstract class?
Are the abstract classes still useful in that scenario?
Yes. They are still useful. They can contain non-static, non-final methods and attributes (protected, private in addition to public), which is not possible even with Java-8 interfaces.
In Linux or MacOS you can use:
date +%s
where
+%s
, seconds since 1970-01-01 00:00:00 UTC. (GNU Coreutils 8.24 Date manual)Example output now 1454000043.
Just use z-index
CSS property as described in the highest liked answer and the nav bar will stick to the top.
Example:
<div class="navigation">
<nav>
<ul>
<li>Home</li>
<li>Contact</li>
</ul>
</nav>
.navigation {
/* fixed keyword is fine too */
position: sticky;
top: 0;
z-index: 100;
/* z-index works pretty much like a layer:
the higher the z-index value, the greater
it will allow the navigation tag to stay on top
of other tags */
}
=Sumifs(B:B,A:A,">=1/1/2013",A:A,"<=1/31/2013")
The beauty of this formula is you can add more data to columns A and B and it will just recalculate.
Factory methods should be considered as an alternative to constructors - mostly when constructors aren't expressive enough, ie.
class Foo{
public Foo(bool withBar);
}
is not as expressive as:
class Foo{
public static Foo withBar();
public static Foo withoutBar();
}
Factory classes are useful when you need a complicated process for constructing the object, when the construction need a dependency that you do not want for the actual class, when you need to construct different objects etc.
If you’re running JQuery on a production site, which library should you load? JQuery.js or JQuery.min.js? The short answer is, they are essentially the same, with the same functionality.
One version is long, while the other is the minified version. The minified is compressed to save space and page load time. White spaces have been removed in the minified version making them jibberish and impossible to read.
If you’re going to run the JQuery library on a production site, I recommend that you use the minified version, to decrease page load time, which Google now considers in their page ranking.
Another good option is to use Google’s online javascript library. This will save you the hassle of downloading the library, as well as uploading to your site. In addition, your site also does not use resources when JQuery is loaded.
The latest JQuery minified version from Google is available here.
You can link to it in your pages using:
http://ulyssesonline.com/2010/12/03/jquery-js-or-jquery-min-js/
The brief points:
If the request header had already been set, then the new value MUST be concatenated to the existing value using a U+002C COMMA followed by a U+0020 SPACE for separation.
UAs MAY give the User-Agent header an initial value, but MUST allow authors to append values to it.
However - After searching through the framework XHR in jQuery they don't allow you to change the User-Agent or Referer headers. The closest thing:
// Set header so the called script knows that it's an XMLHttpRequest
xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
I'm leaning towards the opinion that what you want to do is being denied by a security policy in FF - if you want to pass some custom Referer
type header you could always do:
xhr.setRequestHeader('X-Alt-Referer', 'http://www.google.com');
In your case, when you want a string in the end (in order to insert commas), you can also just use the Number.toFixed()
function, however, this will perform rounding.
I like this short video here mesos learning material
with bare metal clusters, you would need to spawn stacks like HDFS, SPARK, MR etc... so if you launch tasks related to these using only bare metal cluster management, there will be a lot cold starting time.
with mesos, you can install these services on top of the bare metals and you can avoid the bring up time of those base services. This is something mesos does well. and can be utilised by kubernetes building on top of it.
Virtualenv is a tool to create isolated Python environments.
Let's say you're working in 2 different projects, A and B. Project A is a web project and the team is using the following packages:
The project B is also a web project but your team is using:
The machine that you're working doesn't have any version of django, what should you do? Install django 1.4? django 1.6? If you install django 1.4 globally would be easy to point to django 1.6 to work in project A?
Virtualenv is your solution! You can create 2 different virtualenv's, one for project A and another for project B. Now, when you need to work in project A, just activate the virtualenv for project A, and vice-versa.
A better tip when using virtualenv is to install virtualenvwrapper to manage all the virtualenv's that you have, easily. It's a wrapper for creating, working, removing virtualenv's.
Multiply by 2, round, then divide by 2
if you want nearest quarter, multiply by 4, divide by 4, etc
In my case size of the index.php file was zero. I copied the original file back and it worked.
However, no idea about what erased the content of index.php.
Swift: Ui Button create programmatically
let myButton = UIButton()
myButton.titleLabel!.frame = CGRectMake(15, 54, 300, 500)
myButton.titleLabel!.text = "Button Label"
myButton.titleLabel!.textColor = UIColor.redColor()
myButton.titleLabel!.textAlignment = .Center
myButton.addTarget(self,action:"Action:",forControlEvents:UIControlEvent.TouchUpInside)
self.view.addSubview(myButton)
<script type="text/javascript">
$(document).ready(function() {
$(this).attr("title", "sometitle");
});
</script>
Another solution would be to pass the textbox (or control you want to modify) into the method that will manipulate it as a parameter.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
TestClass test = new TestClass();
test.ModifyText(textBox1);
}
}
public class TestClass
{
public void ModifyText(TextBox textBox)
{
textBox.Text = "New text";
}
}
Your vector<string> userString
has size 0
, so the loop is never entered. You could start with a vector of a given size:
vector<string> userString(10);
string word;
string sentence;
for (decltype(userString.size()) i = 0; i < userString.size(); ++i)
{
cin >> word;
userString[i] = word;
sentence += userString[i] + " ";
}
although it is not clear why you need the vector at all:
string word;
string sentence;
for (int i = 0; i < 10; ++i)
{
cin >> word;
sentence += word + " ";
}
If you don't want to have a fixed limit on the number of input words, you can use std::getline
in a while
loop, checking against a certain input, e.g. "q"
:
while (std::getline(std::cin, word) && word != "q")
{
sentence += word + " ";
}
This will add words to sentence
until you type "q".
You have 2 methods to check whether the string is empty or not:
Let's suppose your string name is NSString *strIsEmpty
.
Method 1:
if(strIsEmpty.length==0)
{
//String is empty
}
else
{
//String is not empty
}
Method 2:
if([strIsEmpty isEqualToString:@""])
{
//String is empty
}
else
{
//String is not empty
}
Choose any of the above method and get to know whether string is empty or not.
You can embed websites into another website using the <embed>
tag, like so:
<embed src="http://www.example.com" style="width:500px; height: 300px;">
You can change the height, width, and URL to suit your needs.
The <embed>
tag is the most up-to-date way to embed websites, as it was introduced with HTML5.
Well yea, they are the same, but....!
window.location
is not working on some Internet Explorer browsers.
You probably don't have the six
Python module installed. You can find it on pypi.
To install it:
$ easy_install six
(if you have pip
installed, use pip install six
instead)
I use iterator and a while loop to store the various window handles and then switch back and forth.
//Click your link
driver.findElement(By.xpath("xpath")).click();
//Get all the window handles in a set
Set <String> handles =driver.getWindowHandles();
Iterator<String> it = handles.iterator();
//iterate through your windows
while (it.hasNext()){
String parent = it.next();
String newwin = it.next();
driver.switchTo().window(newwin);
//perform actions on new window
driver.close();
driver.switchTo().window(parent);
}
All above answers are good but for information, we can use int.TryParse
which is safe to convert string to int , example
// TryParse returns true if the conversion succeeded
// and stores the result in j.
int j;
if (Int32.TryParse("-105", out j))
Console.WriteLine(j);
else
Console.WriteLine("String could not be parsed.");
// Output: -105
TryParse never throws an exception—even on invalid input and null. It is overall preferable to int.Parse in most program contexts.

After looking for a way to solve this problem, without loading any Python 3 module or extra mathematical operations, I solved the problem using only str.format() e .float(). I think this way is faster than using other mathematical operations, like in the most commom solution. I needed a fast solution because I work with a very very large dataset and so for its working very well here.
def truncate_number(f_number, n_decimals):
strFormNum = "{0:." + str(n_decimals+5) + "f}"
trunc_num = float(strFormNum.format(f_number)[:-5])
return(trunc_num)
# Testing the 'trunc_num()' function
test_num = 1150/252
[(idx, truncate_number(test_num, idx)) for idx in range(0, 20)]
It returns the following output:
[(0, 4.0),
(1, 4.5),
(2, 4.56),
(3, 4.563),
(4, 4.5634),
(5, 4.56349),
(6, 4.563492),
(7, 4.563492),
(8, 4.56349206),

Solution:
public Response Get(string jsonData) {
var json = JsonConvert.DeserializeObject<modelname>(jsonData);
var data = StoredProcedure.procedureName(json.Parameter, json.Parameter, json.Parameter, json.Parameter);
return data;
}
Model:
public class modelname {
public long parameter{ get; set; }
public int parameter{ get; set; }
public int parameter{ get; set; }
public string parameter{ get; set; }
}
You can use Replace instead of INSERT ... ON DUPLICATE KEY UPDATE.
You should use the exit
keyword.
First of all, there is no real folder concept in S3.
You definitely can have a file @ '/folder/subfolder/myfile.txt'
and no folder nor subfolder.
To "simulate" a folder in S3, you must create an empty file with a '/' at the end of its name (see Amazon S3 boto - how to create a folder?)
For your problem, you should probably use the method get_all_keys
with the 2 parameters : prefix
and delimiter
https://github.com/boto/boto/blob/develop/boto/s3/bucket.py#L427
for key in bucket.get_all_keys(prefix='first-level/', delimiter='/'):
print(key.name)

Command to get the database backup from linux machine terminal.
sqlcmd -S localhost -U SA -Q "BACKUP DATABASE [demodb] TO DISK = N'/var/opt/mssql/data/demodb.bak' WITH NOFORMAT, NOINIT, NAME = 'demodb-full', SKIP, NOREWIND, NOUNLOAD, STATS = 10"
That's Media Queries. It allows you to apply part of CSS rules only to the specific devices on specific configuration.
According to the docs, you want to export of type del (the default delimiter looks like a comma, which is what you want). See the doc page for more information on the EXPORT command.
The Linq extension method Any could work for you...
buildingStatus.Any(item => item.GetCharValue() == v.Status)
How can you get the tree-like view of commits in terminal?
git log --graph --oneline --all
is a good start.
You may get some strange letters. They are ASCII codes for colors and structure. To solve this problem add the following to your .bashrc
:
export LESS="-R"
such that you do not need use Tig's ASCII filter by
git log --graph --pretty=oneline --abbrev-commit | tig // Masi needed this
The article text-based graph from Git-ready contains other options:
git log --graph --pretty=oneline --abbrev-commit
Regarding the article you mention, I would go with Pod's answer: ad-hoc hand-made output.
Jakub Narebski mentions in the comments tig, a ncurses-based text-mode interface for git. See their releases.
It added a --graph
option back in 2007.
.NET can do it with its System.Speech namespace.
You would have to convert to .wav first or capture the audio live from the mic.
Details on implementation can be found here: Transcribing Audio with .NET
# mysqladmin -u root -p status
Output:
Enter password:
Uptime: 4 Threads: 1 Questions: 62 Slow queries: 0 Opens: 51 Flush tables: 1 Open tables: 45 Queries per second avg: 15.500
It means MySQL serer is running
If server is not running then it will dump error as follows
# mysqladmin -u root -p status
Output :
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
So Under Debian Linux you can type following command
# /etc/init.d/mysql status
This simple solution works natively and implements a smooth scroll to any position.
It avoids using anchor links (those with #
) that, in my opinion, are useful if you want to link to a section, but are not so comfortable in some situations, specially when pointing to top which could lead to two different URLs pointing to the same location (http://www.example.org and http://www.example.org/#).
Put an id to the tag you want to scroll to, for example your first section, which answers this question, but the id could be placed everywhere in the page.
<body>
<section id="top">
<!-- your content -->
</section>
<div id="another"><!-- more content --></div>
Then as a button you can use a link, just edit the onclick attribute with a code like this.
<a onclick="document.getElementById('top').scrollIntoView({ behavior: 'smooth', block: 'start', inline: 'nearest' })">Click me</a>
Where the argument of document.getElementById
is the id of the tag you want to scroll to after click.
i like to use a littly tiny library called class-transformer.
it can handle nested-objects, map strings to date-objects and handle different json-property-names a lot more.
Maybe worth a look.
import { Type, plainToClass, Expose } from "class-transformer";
import 'reflect-metadata';
export class Employee{
@Expose({ name: "uid" })
id: number;
firstname: string;
lastname: string;
birthdate: Date;
maxWorkHours: number;
department: string;
@Type(() => Permission)
permissions: Permission[] = [];
typeOfEmployee: string;
note: string;
@Type(() => Date)
lastUpdate: Date;
}
export class Permission {
type : string;
}
let json:string = {
"uid": 123,
"department": "<anystring>",
"typeOfEmployee": "<anystring>",
"firstname": "<anystring>",
"lastname": "<anystring>",
"birthdate": "<anydate>",
"maxWorkHours": 1,
"username": "<anystring>",
"permissions": [
{'type' : 'read'},
{'type' : 'write'}
],
"lastUpdate": "2020-05-08"
}
console.log(plainToClass(Employee, json));
```
With all due respect to all involved parties; I'm very surprised to see how many of you could clear the entire fragment back stack with a simple
fm.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
According to Android documentation (regarding the name
argument - the "null" in the claimed working proposals).
If null, only the top state is popped
Now, I do realize that I'm lacking knowledge of your particular implementations (like how many entries you have in the back stack at the given point in time), but I would bet all my money on the accepted answer when expecting a well defined behaviour over a wider range of devices and vendors:
(for reference, something along with this)
FragmentManager fm = getFragmentManager(); // or 'getSupportFragmentManager();'
int count = fm.getBackStackEntryCount();
for(int i = 0; i < count; ++i) {
fm.popBackStack();
}
The standard principle is separate event handlers shouldn't depend upon the order they are called. If they do depend upon the order they should not be separate.
Otherwise, you register one event handler as being 'first' and someone else then registers their event handler as 'first' and you're back in the same mess as before.
You can definitely use the section tag as a container. It is there to group content in a more semantically significant way than with a div or as the html5 spec says:
The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading. http://www.w3.org/TR/html5/sections.html#the-section-element

You are misusing the API.
Here's the situation: in ASP.NET, only one thread can handle a request at a time. You can do some parallel processing if necessary (borrowing additional threads from the thread pool), but only one thread would have the request context (the additional threads do not have the request context).
This is managed by the ASP.NET SynchronizationContext
.
By default, when you await
a Task
, the method resumes on a captured SynchronizationContext
(or a captured TaskScheduler
, if there is no SynchronizationContext
). Normally, this is just what you want: an asynchronous controller action will await
something, and when it resumes, it resumes with the request context.
So, here's why test5
fails:
Test5Controller.Get
executes AsyncAwait_GetSomeDataAsync
(within the ASP.NET request context).AsyncAwait_GetSomeDataAsync
executes HttpClient.GetAsync
(within the ASP.NET request context).HttpClient.GetAsync
returns an uncompleted Task
.AsyncAwait_GetSomeDataAsync
awaits the Task
; since it is not complete, AsyncAwait_GetSomeDataAsync
returns an uncompleted Task
.Test5Controller.Get
blocks the current thread until that Task
completes.Task
returned by HttpClient.GetAsync
is completed.AsyncAwait_GetSomeDataAsync
attempts to resume within the ASP.NET request context. However, there is already a thread in that context: the thread blocked in Test5Controller.Get
.Here's why the other ones work:
test1
, test2
, and test3
): Continuations_GetSomeDataAsync
schedules the continuation to the thread pool, outside the ASP.NET request context. This allows the Task
returned by Continuations_GetSomeDataAsync
to complete without having to re-enter the request context.test4
and test6
): Since the Task
is awaited, the ASP.NET request thread is not blocked. This allows AsyncAwait_GetSomeDataAsync
to use the ASP.NET request context when it is ready to continue.And here's the best practices:
async
methods, use ConfigureAwait(false)
whenever possible. In your case, this would change AsyncAwait_GetSomeDataAsync
to be var result = await httpClient.GetAsync("http://stackoverflow.com", HttpCompletionOption.ResponseHeadersRead).ConfigureAwait(false);
Task
s; it's async
all the way down. In other words, use await
instead of GetResult
(Task.Result
and Task.Wait
should also be replaced with await
).That way, you get both benefits: the continuation (the remainder of the AsyncAwait_GetSomeDataAsync
method) is run on a basic thread pool thread that doesn't have to enter the ASP.NET request context; and the controller itself is async
(which doesn't block a request thread).

awaiters use SynchronizationContext

You can think of these as the opposites of one another.
When you free an area of memory, but still keep a pointer to it, that pointer is dangling:
char *c = malloc(16);
free(c);
c[1] = 'a'; //invalid access through dangling pointer!
When you lose the pointer, but keep the memory allocated, you have a memory leak:
void myfunc()
{
char *c = malloc(16);
} //after myfunc returns, the the memory pointed to by c is not freed: leak!
Yes... I am using Hue 3.7.0 - The Hadoop UI and to get current date/time information we can use below commands in Hive:

However, in Impala you will find that only below command is working to get date/time details:

You can use a special React
attribute called ref
and then match the real DOM nodes in the onChange
event using React
's getDOMNode()
function:
handleClick: function(event) {
if (event.target === this.refs.prev.getDOMNode()) {
...
}
}
render: function() {
...
<button ref="prev" onClick={this.handleClick}>Previous question</button>
<button ref="next" onClick={this.handleClick}>Next question</button>
...
}
And, if you want to verify that you HAVEN'T broken your relationships and introduced orphans, once you have re-armed your checks, i.e.
ALTER TABLE foo CHECK CONSTRAINT ALL
or
ALTER TABLE foo CHECK CONSTRAINT FK_something
then you can run back in and do an update against any checked columns like so:
UPDATE myUpdatedTable SET someCol = someCol, fkCol = fkCol, etc = etc
And any errors at that point will be due to failure to meet constraints.

If you want to find all commits where commit message contains given word, use
$ git log --grep=word
If you want to find all commits where "word" was added or removed in the file contents (to be more exact: where number of occurences of "word" changed), i.e. search the commit contents, use so called 'pickaxe' search with
$ git log -Sword
In modern git there is also
$ git log -Gword
to look for differences whose added or removed line matches "word" (also commit contents).
Note that -G
by default accepts a regex, while -S
accepts a string, but can be modified to accept regexes using the --pickaxe-regex
.
To illustrate the difference between
-S<regex> --pickaxe-regex
and-G<regex>
, consider a commit with the following diff in the same file:+ return !regexec(regexp, two->ptr, 1, ®match, 0); ... - hit = !regexec(regexp, mf2.ptr, 1, ®match, 0);
While
git log -G"regexec\(regexp"
will show this commit,git log -S"regexec\(regexp" --pickaxe-regex
will not (because the number of occurrences of that string did not change).
With Git 2.25.1 (Feb. 2020), the documentation is clarified around those regexes.
See commit 9299f84 (06 Feb 2020) by Martin Ågren (``).

Keep in mind the second parameter to @Html.HiddenFor will only be used to set the value when it can't find route or model data matching the field. Darin is correct, use view model.
You can use the .not() method:
$(".content_box a").not(".button")
Alternatively, you can also use the :not() selector:
$(".content_box a:not('.button')")
There is little difference between the two approaches, except .not()
is more readable (especially when chained) and :not()
is very marginally faster. See this Stack Overflow answer for more info on the differences.
I am using Windows 10 and overcame this issue by running the pip install mysql-connector

Html.Label
- Just creates a label tag with whatever the string passed into the constructor is
Html.LabelFor
- Creates a label for that specific property. This is strongly typed. By default, this will just do the name of the property (in the below example, it'll output MyProperty if that Display attribute wasn't there). Another benefit of this is you can set the display property in your model and that's what will be put here:
public class MyModel
{
[Display(Name="My property title")
public class MyProperty{get;set;}
}
In your view:
Html.LabelFor(x => x.MyProperty) //Outputs My property title
In the above, LabelFor will display <label for="MyProperty">My property title</label>
. This works nicely so you can define in one place what the label for that property will be and have it show everywhere.
If are using jQuery, grep may be useful:

You need to slightly modify your compare
function and use functools.cmp_to_key
to pass it to sorted
. Example code:
import functools
lst = [list(range(i, i+5)) for i in range(5, 1, -1)]
def fitness(item):
return item[0]+item[1]+item[2]+item[3]+item[4]
def compare(item1, item2):
return fitness(item1) - fitness(item2)
sorted(lst, key=functools.cmp_to_key(compare))
Output:
[[2, 3, 4, 5, 6], [3, 4, 5, 6, 7], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]]
Works :)
This is my solution. I Hide and then confirm check
onclick="return ConfirmSubmit(this);" />
function ConfirmSubmit(sender)
{
sender.disabled = true;
var displayValue = sender.style.
sender.style.display = 'none'
if (confirm('Seguro que desea entregar los paquetes?')) {
sender.disabled = false
return true;
}
sender.disabled = false;
sender.style.display = displayValue;
return false;
}
Although Git has an internal implementation of diff, you can set up an external tool instead.
There are two different ways to specify an external diff tool:
GIT_EXTERNAL_DIFF
and the GIT_DIFF_OPTS
environment variables.git config
See also:
git diff --help
When doing a git diff
, Git checks both the settings of above environment variables and its .gitconfig
file.
By default, Git passes the following seven arguments to the diff program:
path old-file old-hex old-mode new-file new-hex new-mode
You typically only need the old-file and new-file parameters. Of course most diff tools only take two file names as an argument. This means that you need to write a small wrapper-script, which takes the arguments which Git provides to the script, and hands them on to the external git program of your choice.
Let's say you put your wrapper-script under ~/scripts/my_diff.sh
:
#!/bin/bash
# un-comment one diff tool you'd like to use
# side-by-side diff with custom options:
# /usr/bin/sdiff -w200 -l "$2" "$5"
# using kdiff3 as the side-by-side diff:
# /usr/bin/kdiff3 "$2" "$5"
# using Meld
/usr/bin/meld "$2" "$5"
# using VIM
# /usr/bin/vim -d "$2" "$5"
you then need to make that script executable:
chmod a+x ~/scripts/my_diff.sh
you then need to tell Git how and where to find your custom diff wrapper script. You have three choices how to do that: (I prefer editing the .gitconfig file)
Using GIT_EXTERNAL_DIFF
, GIT_DIFF_OPTS
e.g. in your .bashrc or .bash_profile file you can set:
GIT_EXTERNAL_DIFF=$HOME/scripts/my_diff.sh
export GIT_EXTERNAL_DIFF
Using git config
use "git config" to define where your wrapper script can be found:
git config --global diff.external ~/scripts/my_diff.sh
Editing your ~/.gitconfig
file
you can edit your ~/.gitconfig
file to add these lines:
[diff]
external = ~/scripts/my_diff.sh
Note:
Similarly to installing your custom diff tool, you can also install a custom merge-tool, which could be a visual merging tool to better help visualizing the merge. (see the progit.org page)
See: http://fredpalma.com/518/visual-diff-and-merge-tool/ and https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration
You can use the "Company Search" operation in the Company Fundamentals API here: http://www.mergent.com/servius/
SELECT TOP 1 * FROM foo ORDER BY Dates DESC
Will return one result with the latest date.
SELECT * FROM foo WHERE foo.Dates = (SELECT MAX(Dates) FROM foo)
Will return all results that have the same maximum date, to the milissecond.
This is for SQL Server. I'll leave it up to you to use the DATEPART function if you want to use dates but not times.
As someone who is also learning pandas I found the other answers a bit implicit as pandas hides most of the work behind the scenes. Namely in how the operation works by automatically matching up column and index names. This code should be equivalent to a step by step version of @exp1orer's accepted answer
With the df
, I'll call it by the alias state_office_sales
:
sales

WA 2 163942
4 369858
6 959285
state_total_sales
is state_office_sales
grouped by total sums in index level 0
(leftmost).
In: state_total_sales = df.groupby(level=0).sum()
state_total_sales
Out:
sales
state
AZ 2448009
CA 2832270
CO 1495486
WA 595859
Because the two dataframes share an index-name and a column-name pandas will find the appropriate locations through shared indexes like:
In: state_office_sales / state_total_sales
Out:
sales
state office_id
AZ 2 0.448640
4 0.125865
6 0.425496
CA 1 0.288022
3 0.322169

5 0.435425
WA 2 0.321689
4 0.346325
6 0.331986
To illustrate this even better, here is a partial total with a XX
that has no equivalent. Pandas will match the location based on index and column names, where there is no overlap pandas will ignore it:
In: partial_total = pd.DataFrame(
data = {'sales' : [2448009, 595859, 99999]},
index = ['AZ', 'WA', 'XX' ]
)
partial_total.index.name = 'state'
Out:
sales
state
AZ 2448009
WA 595859
XX 99999
In: state_office_sales / partial_total
Out:
sales
state office_id

4 0.125865
6 0.425496

5 NaN
CO 1 NaN
3 NaN
5 NaN
WA 2 0.321689
4 0.346325
6 0.331986
This becomes very clear when there are no shared indexes or columns. Here missing_index_totals
is equal to state_total_sales
except that it has a no index-name.
In: missing_index_totals = state_total_sales.rename_axis("")
missing_index_totals
Out:
sales
AZ 2448009
CA 2832270
CO 1495486
WA 595859
In: state_office_sales / missing_index_totals
Out: ValueError: cannot join with no overlapping index names
According to the Android developers guide for android.hardware.Camera
, they state:
We recommend using the new android.hardware.camera2 API for new applications.
On the information page about android.hardware.camera2
, (linked above), it is stated:
The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.
When you check that documentation you'll find that the implementation of these 2 Camera API's are very different.
For example getting camera orientation on android.hardware.camera
@Override
public int getOrientation(final int cameraId) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(cameraId, info);
return info.orientation;
}
Versus android.hardware.camera2
@Override
public int getOrientation(final int cameraId) {
try {
CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
String[] cameraIds = manager.getCameraIdList();
CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
} catch (CameraAccessException e) {
// TODO handle error properly or pass it on
return 0;
}
}
This makes it hard to switch from one to another and write code that can handle both implementations.
Note that in this single code example I already had to work around the fact that the olde camera API works with int
primitives for camera IDs while the new one works with String
objects. For this example I quickly fixed that by using the int as an index in the new API. If the camera's returned aren't always in the same order this will already cause issues. Alternative approach is to work with String objects and String representation of the old int cameraIDs which is probably safer.
Now to work around this huge difference you can implement an interface first and reference that interface in your code.
Here I'll list some code for that interface and the 2 implementations. You can limit the implementation to what you actually use of the camera API to limit the amount of work.
In the next section I'll quickly explain how to load one or another.
The interface wrapping all you need, to limit this example I only have 2 methods here.
public interface CameraSupport {
CameraSupport open(int cameraId);
int getOrientation(int cameraId);
}
Now have a class for the old camera hardware api:
@SuppressWarnings("deprecation")
public class CameraOld implements CameraSupport {
private Camera camera;
@Override
public CameraSupport open(final int cameraId) {
this.camera = Camera.open(cameraId);
return this;
}
@Override
public int getOrientation(final int cameraId) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(cameraId, info);
return info.orientation;
}
}
And another one for the new hardware api:
public class CameraNew implements CameraSupport {
private CameraDevice camera;
private CameraManager manager;
public CameraNew(final Context context) {
this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
}
@Override
public CameraSupport open(final int cameraId) {
try {
String[] cameraIds = manager.getCameraIdList();
manager.openCamera(cameraIds[cameraId], new CameraDevice.StateCallback() {
@Override
public void onOpened(CameraDevice camera) {
CameraNew.this.camera = camera;
}
@Override
public void onDisconnected(CameraDevice camera) {
CameraNew.this.camera = camera;
// TODO handle
}
@Override
public void onError(CameraDevice camera, int error) {
CameraNew.this.camera = camera;
// TODO handle
}
}, null);
} catch (Exception e) {
// TODO handle
}
return this;
}
@Override
public int getOrientation(final int cameraId) {
try {
String[] cameraIds = manager.getCameraIdList();
CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
} catch (CameraAccessException e) {
// TODO handle
return 0;
}
}
}
Now to load either your CameraOld
or CameraNew
class you'll have to check the API level since CameraNew
is only available from api level 21.
If you have dependency injection set up already you can do so in your module when providing the CameraSupport
implementation. Example:
@Module public class CameraModule {
@Provides
CameraSupport provideCameraSupport(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
return new CameraNew(context);
} else {
return new CameraOld();
}
}
}
If you don't use DI you can just make a utility or use Factory pattern to create the proper one. Important part is that the API level is checked.
If it's GNU diff then you should just be able to point it at the two directories and use the -r option.
Otherwise, try using
for i in $(\ls -d ./dir1/*); do diff ${i} dir2; done
N.B. As pointed out by Dennis in the comments section, you don't actually need to do the command substitution on the ls. I've been doing this for so long that I'm pretty much doing this on autopilot and substituting the command I need to get my list of files for comparison.
Also I forgot to add that I do '\ls' to temporarily disable my alias of ls to GNU ls so that I lose the colour formatting info from the listing returned by GNU ls.
For performance, it usually best to make the code as simple and clear as possible and this will often perform well (as the JIT will optimise this code best). In your case, the simplest examples are also likely to be the fastest.
I would do either
int cmp = a > b ? +1 : a < b ? -1 : 0;
or a longer version
int cmp;
if (a > b)
cmp = +1;
else if (a < b)
cmp = -1;
else
cmp = 0;
or
int cmp = Integer.compare(a, b); // in Java 7
int cmp = Double.compare(a, b); // before Java 7
It's best not to create an object if you don't need to.
Performance wise, the first is best.
If you know for sure that you won't get an overflow you can use
int cmp = a - b; // if you know there wont be an overflow.
you won't get faster than this.
There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.
If you have a long running background work you should specify this by using the correct Task Option.
You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.
Try this, but I don't think it will work because you're not supposed to be able to change this
Put this line in an htaccess file in the directory you want the setting to be enabled:
php_value allow_url_fopen On
Note that this setting will only apply to PHP file's in the same directory as the htaccess file.

font-size:9px;
min-height:40px;
}
remove the lines :
-moz-box-shadow: 3px 3px 4px #999999;
-webkit-box-shadow: 3px 3px 4px #999999;
box-shadow: 3px 3px 4px #999999;
This basically gives a shadow gradient only to the footer. In Firefox, it is the first line that is causing the problem.
For raising events concisely:
public static void Raise(this EventHandler handler, object sender, EventArgs e)
{
if (handler != null)
{
handler(sender, e);
}
}
public static void Raise<T>(this EventHandler<T> handler, object sender, T e) where T : EventArgs
{
if (handler != null)
{
handler(sender, e);
}
}
Usage:
public event EventHandler Bar;
public void Foo()
{
Bar.Raise(this, EventArgs.Empty);
}
There's a bit of discussion about potential thread-safety issues here. Since .NET 4, the above form is thread-safe, but requires rearranging and some locks if using an older version.

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.
Using JACOB call Office Word is a 100% perfect solution. But it only supports on Windows platform because need Office Word installed.
Using JACOB API call Office Word to convert doc/docx to pdf.
public void convertDocx2pdf(String docxFilePath) {
File docxFile = new File(docxFilePath);
String pdfFile = docxFilePath.substring(0, docxFilePath.lastIndexOf(".docx")) + ".pdf";
if (docxFile.exists()) {
if (!docxFile.isDirectory()) {
ActiveXComponent app = null;
long start = System.currentTimeMillis();
try {
ComThread.InitMTA(true);
app = new ActiveXComponent("Word.Application");
Dispatch documents = app.getProperty("Documents").toDispatch();
Dispatch document = Dispatch.call(documents, "Open", docxFilePath, false, true).toDispatch();
File target = new File(pdfFile);
if (target.exists()) {
target.delete();
}
Dispatch.call(document, "SaveAs", pdfFile, 17);
Dispatch.call(document, "Close", false);
long end = System.currentTimeMillis();
logger.info("============Convert Finished:" + (end - start) + "ms");
} catch (Exception e) {
logger.error(e.getLocalizedMessage(), e);
throw new RuntimeException("pdf convert failed.");
} finally {
if (app != null) {
app.invoke("Quit", new Variant[] {});
}
ComThread.Release();
}

CMake is more like a script language if comparing it with other ways to create Makefile (e.g. make or qmake). It is not very cool like Python, but still.
There are no such thing like a "proper way" if looking in various opensource projects how people include directories. But there are two ways to do it.
Crude include_directories will append a directory to the current project and all other descendant projects which you will append via a series of add_subdirectory commands. Sometimes people say that such approach is legacy.
A more elegant way is with target_include_directories. It allows to append a directory for a specific project/target without (maybe) unnecessary inheritance or clashing of various include directories. Also allow to perform even a subtle configuration and append one of the following markers for this command.
PRIVATE - use only for this specified build target
PUBLIC - use it for specified target and for targets which links with this project
INTERFACE -- use it only for targets which links with the current project
PS:
Both commands allow to mark a directory as SYSTEM to give a hint that it is not your business that specified directories will contain warnings.
A similar answer is with other pairs of commands target_compile_definitions/add_definitions, target_compile_options/CMAKE_C_FLAGS
Here the code i used for my app
This code will take a image from url and convert is to a byte array
byte[] logoImage = getLogoImage(IMAGEURL);
private byte[] getLogoImage(String url){
try {
URL imageUrl = new URL(url);
URLConnection ucon = imageUrl.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(500);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
return baf.toByteArray();
} catch (Exception e) {
Log.d("ImageManager", "Error: " + e.toString());
}
return null;
}
To save the image to db i used this code.
public void insertUser(){
SQLiteDatabase db = dbHelper.getWritableDatabase();
String delSql = "DELETE FROM ACCOUNTS";
SQLiteStatement delStmt = db.compileStatement(delSql);
delStmt.execute();
String sql = "INSERT INTO ACCOUNTS (account_id,account_name,account_image) VALUES(?,?,?)";
SQLiteStatement insertStmt = db.compileStatement(sql);
insertStmt.clearBindings();
insertStmt.bindString(1, Integer.toString(this.accId));
insertStmt.bindString(2,this.accName);
insertStmt.bindBlob(3, this.accImage);
insertStmt.executeInsert();
db.close();
}
To retrieve the image back this is code i used.
public Account getCurrentAccount() {
SQLiteDatabase db = dbHelper.getWritableDatabase();
String sql = "SELECT * FROM ACCOUNTS";
Cursor cursor = db.rawQuery(sql, new String[] {});
if(cursor.moveToFirst()){
this.accId = cursor.getInt(0);
this.accName = cursor.getString(1);
this.accImage = cursor.getBlob(2);
}
if (cursor != null && !cursor.isClosed()) {
cursor.close();
}
db.close();
if(cursor.getCount() == 0){
return null;
} else {
return this;
}
}
Finally to load this image to a imageview
logoImage.setImageBitmap(BitmapFactory.decodeByteArray( currentAccount.accImage,
0,currentAccount.accImage.length));
Example to set in the "V" environment variable the most recent file
FOR /F %I IN ('DIR *.* /O:D /B') DO SET V=%I
in a batch file you have to use double prefix in the loop variable:
FOR /F %%I IN ('DIR *.* /O:D /B') DO SET V=%%I
If you use "hg remove b"
against a file with "A" status, which means it has been added but not commited, Mercurial will respond:
not removing b: file has been marked for add (use forget to undo)
This response is a very clear explication of the difference between remove and forget.
My understanding is that "hg forget"
is for undoing an added but not committed file so that it is not tracked by version control; while "hg remove"
is for taking out a committed file from version control.
This thread has a example for using hg remove
against files of 7 different types of status.
The most basic and easiest way to understand (I think):
import java.util.Scanner;
public class ToUpperCase {
static Scanner kb = new Scanner(System.in);
public static String capitalize(String str){
/* Changes 1st letter of every word
in a string to upper case
*/
String[] ss = str.split(" ");
StringBuilder[] sb = new StringBuilder[ss.length];
StringBuilder capped = new StringBuilder("");
str = "";
// Capitalise letters
for (int i = 0; i < ss.length; i++){
sb[i] = new StringBuilder(ss[i]); // Construct and assign
str += Character.toUpperCase(ss[i].charAt(0)); // Only caps
//======================================================//
// Replace 1st letters with cap letters
sb[i].setCharAt(0, str.charAt(i));
capped.append(sb[i].toString() + " "); // Formatting
}
return capped.toString();
}
public static void main(String[] args){
System.out.println(capitalize(kb.nextLine()));
}
}
You don't have the last version of typescript.
Running :
npm install -g typescript
npm
checks if tsc
command is already installed.
And it might be, by another software like Visual Studio
. If so, npm
doesn't override it. So you have to remove the previous deprecated tsc
installed command.
Run where tsc
to know its bin location. It should be in C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\
in windows. Once found, delete the folder, and re-run npm install -g typescript
. This should now install the last version of typescript.
You can try below code will preserve any white-space and new lines in your text.
$str = "
put returns between paragraphs
for linebreak add 2 spaces at end
";
echo preg_replace( "/\r|\n/", "", $str );
There's one more "hack" by using HTTP Referer (we asume that browser window was closed current referer's domain name and curent page's domain name do not match):
session_start();
$_SESSION['somevariable'] = 'somevalue';
if(parse_url($_SERVER["HTTP_REFERER"], PHP_URL_HOST) != $_SERVER["SERVER_NAME"]){
session_destroy();
}
This also has some drawbacks, but it helped me few times.
import json, ast
r = {u'name': u'A', u'primary_key': 1}
ast.literal_eval(json.dumps(r))
will print
{'name': 'A', 'primary_key': 1}
Try:
window > preferences > java > editor > mark occurrences
Select all options available there.
Also go to:
Preferences > General > Editors > Text Editors > Annotations
Compare the settings for 'Occurrences' and 'Write Occurrences'
Make sure that you don't have the 'Text as higlighted' option checked for one of them.
This should fix it.

Try to add the following configuration for surefire plugin in your pom.xml of root project:
<project>
[...]
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
</plugins>
</build>
[...]
</project>
Unfortunately, the Preferences dialog is not always very helpful, but by tweaking around you should be able to get everything working.
To be able to type Swedish characters in Terminal, add the following lines to your ~/.inputrc (most likely you must create this file):
set input-meta on
set output-meta on
set convert-meta off
This should do the work both with utf8 and other codings in bash
, nano
and many other programs. Some programs, like tmux
, also depends on the locale
. Then, adding for instance export LC_ALL=en_US.UTF-8
to your ~/.profile
file should help, but keep in mind that a few (mainly obscure) programs require a standard locale, so if you have trouble running or compiling a program, try going back to LC_ALL=C
.

This one covers using it in the <input>
field:
<input type="date" name="d" min="2011-08-01" max="2011-08-15">
This example of the HTML5 input type "date" combine with the attributes min and max shows how we can restrict the dates a user can input. The attributes min and max are not dependent on each other and can be used independently.
<input type="time" name="t" value="12:00">
The HTML5 input type "time" allows users to choose a corresponding time that is displayed in a 24hour format. If we did not include the default value of "12:00" the time would set itself to the time of the users local machine.
<input type="week" name="w">
The HTML5 Input type week will display the numerical version of the week denoted by a "W" along with the corresponding year.
<input type="month" name="m">
The HTML5 input type month does exactly what you might expect it to do. It displays the month. To be precise it displays the numerical version of the month along with the year.
<input type="datetime" name="dt">
The HTML5 input type Datetime displays the UTC date and time code. User can change the the time steps forward or backward in one minute increments. If you wish to display the local date and time of the user you will need to use the next example datetime-local
<input type="datetime-local" name="dtl" step="7200">
Because datetime steps through one minute at a time, you may want to change the default increment by using the attribute "step". In the following example we will have it increment by two hours by setting the attribute step to 7200 (60seconds X 60 minutes X 2).
This error "Could not load file or assembly 'example' or one of its dependencies. An attempt was made to load a program with an incorrect format" is typically caused by an incorrect application pool configuration.
I had this issue as well, and the text-shadow
wasn't an option because the corners would look bad (unless I had many many shadows), and I didn't want any blur, therefore my only other option was to do the following: Have 2 divs, and for the background div, put a -webkit-text-stroke
on it, which then allows for as big of an outline as you like.
div {_x000D_
font-size: 200px;_x000D_
position: absolute;_x000D_
white-space: nowrap;_x000D_
}_x000D_
_x000D_
.front {_x000D_
color: blue;_x000D_
}_x000D_
_x000D_
.outline {_x000D_
-webkit-text-stroke: 30px red;_x000D_
user-select: none;_x000D_
}
_x000D_
<div class="outline">_x000D_
outline text_x000D_
</div>_x000D_
_x000D_
<div class="front">_x000D_
outline text_x000D_
</div>
_x000D_
Using this, I was able to achieve an outline, because the stroke-width
method was not an option if you want your text to remain legible with a very large outline (because with stroke-width
the outline will start inside the lettering which makes it not legible when the width gets larger than the letters.
Note: the reason I needed such a fat outline was I was emulating the street labels in "google maps" and I wanted a fat white halo around the text. This solution worked perfectly for me.
I had this error returned after using the commit id from a pull request commit id tab. That commit was subsequently squashed and merged. In the github pull request, look for this text: "merged commit xxxxxxx into..." instead of attempting to use the commit ids from the commits tab.
Extending the Throwable class will give you the String property error.stackTraceString
:
val Throwable.stackTraceString: String
get() {
val sw = StringWriter()
val pw = PrintWriter(sw)
this.printStackTrace(pw)
return sw.toString()
}
When your second thread is non-Daemon, your application's primary main thread cannot quit because its exit criteria is being tied to the exit also of non-Daemon thread(s). Threads cannot be forcibly killed in python, therefore your app will have to really wait for the non-Daemon thread(s) to exit. If this behavior is not what you want, then set your second thread as daemon so that it won't hold back your application from exiting.
Visibility is animatable. Check this blog post about it: http://www.greywyvern.com/?post=337
You can see it here too: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_animated_properties
Let's say you have a menu that you want to fade-in and fade-out on mouse hover. If you use opacity:0
only, your transparent menu will still be there and it will animate when you hover the invisible area. But if you add visibility:hidden
, you can eliminate this problem:
div {_x000D_
width:100px;_x000D_
height:20px;_x000D_
}_x000D_
.menu {_x000D_
visibility:hidden;_x000D_
opacity:0;_x000D_
transition:visibility 0.3s linear,opacity 0.3s linear;_x000D_
_x000D_
background:#eee;_x000D_
width:100px;_x000D_
margin:0;_x000D_
padding:5px;_x000D_
list-style:none;_x000D_
}_x000D_
div:hover > .menu {_x000D_
visibility:visible;_x000D_
opacity:1;_x000D_
}
_x000D_
<div>_x000D_
<a href="#">Open Menu</a>_x000D_

AJAX is getting data from the server using Javascript and XML in an asynchronous fashion. Unless you want to download the colour code from the server, that's not what you're really aiming for!
But otherwise you can set the CSS background with Javascript. If you're using a framework like jQuery, it'll be something like this:
$('body').css('background', '#ccc');
Otherwise, this should work:
document.body.style.background = "#ccc";
Instead of thinking of code or classes as thread safe or not, I think it is more helpful to think of actions as being thread-safe. Two actions are thread safe if they will be behave as specified when run from arbitrary threading contexts. In many cases, classes will support some combinations of actions in thread-safe fashion and others not.
For example, many collections like array-lists and hash sets will guarantee that if they are initially accessed exclusively with one thread, and they are never modified after a reference becomes visible to any other threads, they may be read in arbitrary fashion by any combination of threads without interference.
More interestingly, some hash-set collections such as the original non-generic one in .NET, may offer a guarantee that as long as no item is ever removed, and provided that only one thread ever writes to them, any thread that tries to read the collection will behave as though accessing a collection where updates might be delayed and occur in arbitrary order, but which will otherwise behave normally. If thread #1 adds X and then Y, and thread #2 looks for and sees Y and then X, it would be possible for thread #2 to see that Y exists but X doesn't; whether or not such behavior is "thread-safe" would depend upon whether thread #2 is prepared to deal with that possibility.
As a final note, some classes--especially blocking communications libraries--may have a "close" or "Dispose" method which is thread-safe with respect to all other methods, but no other methods that are thread-safe with respect to each other. If a thread performs a blocking read request and a user of the program clicks "cancel", there would be no way for a close request to be issued by the thread that's attempting to perform the read. The close/dispose request, however, may asynchronously set a flag which will cause the read request to be canceled as soon as possible. Once close is performed on any thread, the object would become useless, and all attempts at future actions would fail immediately, but being able to asynchronously terminate any attempted I/O operations is better than require that the close request be synchronized with the read (since if the read blocks forever, the synchronization request would be likewise blocked).
We can use RxJava (very powerful reactive extension library)
LinkedList<User> users = new LinkedList<>();
users.add(new User(1, "User1"));
users.add(new User(2, "User2"));
users.add(new User(3, "User3"));
User userFound = Observable.from(users)
.filter((user) -> user.getId() == 1)
.single().toBlocking().first();
The single operator throws an exception if no user or more then one user is found.
Assuming your WebSocket server is listening on the same port as from which the page is being requested, I would suggest:
function createWebSocket(path) {
var protocolPrefix = (window.location.protocol === 'https:') ? 'wss:' : 'ws:';
return new WebSocket(protocolPrefix + '//' + location.host + path);
}
Then, for your case, call it as follows:
var socket = createWebSocket(location.pathname + '/to/ws');
If you're using the memory you've allocated, then you're not doing anything wrong. It becomes a problem when you write functions (other than main) that allocate memory without freeing it, and without making it available to the rest of your program. Then your program continues running with that memory allocated to it, but no way of using it. Your program and other running programs are deprived of that memory.
Edit: It's not 100% accurate to say that other running programs are deprived of that memory. The operating system can always let them use it at the expense of swapping your program out to virtual memory (</handwaving>
). The point is, though, that if your program frees memory that it isn't using then a virtual memory swap is less likely to be necessary.
Ternary way
my_string.include?('ahr') ? (puts 'String includes ahr') : (puts 'String does not include ahr')
OR
puts (my_string.include?('ahr') ? 'String includes ahr' : 'String not includes ahr')
Based on @StanleyH solution I created an AngularJS directive, demo on jsFiddle.
Easy to use:
<div data-double-scroll-bar-horizontal> {{content}} or static content </div>
For AngularJS developers
For starters:
<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.
This would be the optimal solution:
<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
Since i am little late here but i wanted to share how actually list comprehension works especially nested list comprehension :
New_list= [[float(y) for x in l]
is actually same as :
New_list=[]
for x in l:
New_list.append(x)
And now nested list comprehension :
[[float(y) for y in x] for x in l]
is same as ;
new_list=[]
for x in l:
sub_list=[]
for y in x:
sub_list.append(float(y))
new_list.append(sub_list)
print(new_list)
output:
[[40.0, 20.0, 10.0, 30.0], [20.0, 20.0, 20.0, 20.0, 20.0, 30.0, 20.0], [30.0, 20.0, 30.0, 50.0, 10.0, 30.0, 20.0, 20.0, 20.0], [100.0, 100.0], [100.0, 100.0, 100.0, 100.0, 100.0], [100.0, 100.0, 100.0, 100.0]]

Today I just wrote a post about "Why do we use the letters like “e” in e.preventDefault()?" and I think my answer will make some sense...
At first,let us see the syntax of addEventListener
Normally it will be: target.addEventListener(type, listener[, useCapture]);
And the definition of the parameters of addEventlistener are:
type :A string representing the event type to listen out for.
listener :The object which receives a notification (an object that implements the Event interface) when an event of the specified type occurs. This must be an object implementing the EventListener interface, or a JavaScript function.
(From MDN)
But I think there is one thing should be remarked: When you use Javascript function as the listener, the object that implements the Event interface(object event) will be automatically assigned to the "first parameter" of the function.So,if you use function(e) ,the object will be assigned to "e" because "e" is the only parameter of the function(definitly the first one !),then you can use e.preventDefault to prevent something....
let us try the example as below:
<p>Please click on the checkbox control.</p>
<form>
<label for="id-checkbox">Checkbox</label>
<input type="checkbox" id="id-checkbox"/>
</div>
</form>
<script>
document.querySelector("#id-checkbox").addEventListener("click", function(e,v){
//var e=3;
var v=5;
var t=e+v;
console.log(t);
e.preventDefault();
}, false);
</script>
the result will be : [object MouseEvent]5 and you will prevent the click event.
but if you remove the comment sign like :
<script>
document.querySelector("#id-checkbox").addEventListener("click", function(e,v){
var e=3;
var v=5;
var t=e+v;
console.log(t);
e.preventDefault();
}, false);
</script>
you will get : 8 and an error:"Uncaught TypeError: e.preventDefault is not a function at HTMLInputElement. (VM409:69)".
Certainly,the click event will not be prevented this time.Because the "e" was defined again in the function.
However,if you change the code to:
<script>
document.querySelector("#id-checkbox").addEventListener("click", function(e,v){
var e=3;
var v=5;
var t=e+v;
console.log(t);
event.preventDefault();
}, false);
</script>
every thing will work propertly again...you will get 8 and the click event be prevented...
Therefore, "e" is just a parameter of your function and you need an "e" in you function() to receive the "event object" then perform e.preventDefault(). This is also the reason why you can change the "e" to any words that is not reserved by js.
I tried all the options and none worked.
Only google app scripts helped me.
source : https://ctrlq.org/code/19649-find-duplicate-rows-in-google-sheets
At the top of your document
1.- go to tools > script editor
2.- set the name of your script
3.- paste this code :
function findDuplicates() {
// List the columns you want to check by number (A = 1)
var CHECK_COLUMNS = [1];
// Get the active sheet and info about it
var sourceSheet = SpreadsheetApp.getActiveSheet();
var numRows = sourceSheet.getLastRow();
var numCols = sourceSheet.getLastColumn();
// Create the temporary working sheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
var newSheet = ss.insertSheet("FindDupes");
// Copy the desired rows to the FindDupes sheet
for (var i = 0; i < CHECK_COLUMNS.length; i++) {
var sourceRange = sourceSheet.getRange(1,CHECK_COLUMNS[i],numRows);
var nextCol = newSheet.getLastColumn() + 1;
sourceRange.copyTo(newSheet.getRange(1,nextCol,numRows));
}
// Find duplicates in the FindDupes sheet and color them in the main sheet
var dupes = false;
var data = newSheet.getDataRange().getValues();
for (i = 1; i < data.length - 1; i++) {
for (j = i+1; j < data.length; j++) {
if (data[i].join() == data[j].join()) {
dupes = true;
sourceSheet.getRange(i+1,1,1,numCols).setBackground("red");
sourceSheet.getRange(j+1,1,1,numCols).setBackground("red");
}
}
}
// Remove the FindDupes temporary sheet
ss.deleteSheet(newSheet);
// Alert the user with the results
if (dupes) {
Browser.msgBox("Possible duplicate(s) found and colored red.");
} else {
Browser.msgBox("No duplicates found.");
}
};
4.- save and run
In less than 3 seconds, my duplicate row was colored. Just copy-past the script.

I hope this helps.
Step over the next function(F10)
button beside Resume(F8)
in the upper top center of the chrome until you freeze the popup you want to see. Your form should look like this :
<form action="myprocessingscript.php" method="POST">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
and the PHP
<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
$data = $_POST['field1'] . '-' . $_POST['field2'] . "\r\n";
$ret = file_put_contents('/tmp/mydata.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "$ret bytes written to file";
}
}
else {
die('no post data to process');
}
I wrote to /tmp/mydata.txt
because this way I know exactly where it is. using data.txt
writes to that file in the current working directory which I know nothing of in your example.
file_put_contents
opens, writes and closes files for you. Don't mess with it.

If the schema of id is not of type ObjectId you cannot operate with function : findbyId()
I try to add following code:
private static final int MY_CAMERA_REQUEST_CODE = 100;
@RequiresApi(api = Build.VERSION_CODES.M)
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_REQUEST_CODE);
}
On onCreate Function and this following code:
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == MY_CAMERA_REQUEST_CODE) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
}
}
}
And this worked for me :)
With Spring Data Jpa, we can use this method:
/*
* (non-Javadoc)
* @see org.springframework.data.jpa.repository.JpaSpecificationExecutor#count(org.springframework.data.jpa.domain.Specification)
*/
@Override
public long count(@Nullable Specification<T> spec) {
return executeCountQuery(getCountQuery(spec, getDomainClass()));
}
This is exactly what ajax is for. See here:
Basically, you ajax/test.php and put the returned HTML code to the element which has the result id.
$('#result').load('ajax/test.php');
Of course, you will need to put the functionality which takes time to a new php file (or call the old one with a GET parameter which will activate that functionality only).
I don't know that much about batch files but couldn't you have a pre-made batch file copied from the home directory to the path you have that would return a list of the names of the files then use that name?
Here is a link I think might be helpful in making the pre-made batch file.
I had a similar problem and I did something like the below mentioned steps with my Path environment variable to fix the problem
Located where my Anaconda3 was installed. I run Windows 7. Mine is located at C:\ProgramData\Anaconda3.
Open Control Panel - System - Advanced System Settings, under Advanced tab click on Environment Variables.
Under System Variables, located "Path" add the following: C:\ProgramData\Anaconda3\Scripts;C:\ProgramData\Anaconda3\;
Save and open new terminal. type in "conda". It worked for me.
Hope these steps help
You are trying to set "++" on a jQuery element!
YOu could declare a js variable
var counter = 0;
and in jQuery code do:
$("#counter").html(counter++);
Changes all spaces to tab
:%s/\s/\t/g

This is what worked for me.
Go to File -> Project Structure and select the "Dependencies" tab on the right panel of the window. Then change the "Module SDK" using the drop-down like this. Then apply changes.
You could store those objects on a database. If you don't want the overhead of a full blown database server you can use an embedded one like HSQLDB. Then you can use Hibernate or BeanKeeper (simpler to use) or other ORM to map objects to tables. You keep using the OO model and get the advanced storage and querying benefits from a database.
Install react-native globally by using the following command

Suppose I want to increase the driver memory in runtime using Spark Session:
s2 = SparkSession.builder.config("spark.driver.memory", "29g").getOrCreate()
Now I want to view the updated settings:
s2.conf.get("spark.driver.memory")
To get all the settings, you can make use of spark.sparkContext._conf.getAll()
Hope this helps
[PrincipalPermission(SecurityAction.Demand, Role = @"BUILTIN\Administrators")]
This will do it without UAC - no need to start a new process. If the running user is member of Admin group as for my case.
I've wondered this myself for years. But i came across a good reason today.
Imagine a file with a record on every line (ex: a CSV file). And that the computer was writing records at the end of the file. But it suddenly crashed. Gee was the last line complete? (not a nice situation)
But if we always terminate the last line, then we would know (simply check if last line is terminated). Otherwise we would probably have to discard the last line every time, just to be safe.
From @NHG comment — works perfectly

To use variables within a query you have to use bindValue()
or bindParam()
. And do not concatenate the variables with " . $variable . "

This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?
You can either use:
<button onclick="window.history.back()">Back</button>
or..
<button onclick="window.history.go(-1)">Back</button>
The difference, of course, is back()
only goes back 1 page but go()
goes back/forward the number of pages you pass as a parameter, relative to your current page.
For SQL Server 2008, I would imagine the procedure is similar...?
You can do this from the template with something like this:
{% if form.instance.some_field %}
{{form.instance.some_field}}
{% else %}
{{form.data.some_field}}
{% endif %}
This will display the instance value (if the form is created with an instance, you can use initial instead if you like), or else display the POST data such as when a validation error occurs.

The code below avoids using the Python hash() function because it will not provide hashes that are consistent across restarts of Python (see hash function in Python 3.3 returns different results between sessions). make_hashable()
will convert the object into nested tuples and make_hash_sha256()
will also convert the repr()
to a base64 encoded SHA256 hash.
import hashlib
import base64
def make_hash_sha256(o):
hasher = hashlib.sha256()
hasher.update(repr(make_hashable(o)).encode())
return base64.b64encode(hasher.digest()).decode()
def make_hashable(o):
if isinstance(o, (tuple, list)):
return tuple((make_hashable(e) for e in o))
if isinstance(o, dict):
return tuple(sorted((k,make_hashable(v)) for k,v in o.items()))
if isinstance(o, (set, frozenset)):
return tuple(sorted(make_hashable(e) for e in o))
return o
o = dict(x=1,b=2,c=[3,4,5],d={6,7})
print(make_hashable(o))
# (('b', 2), ('c', (3, 4, 5)), ('d', (6, 7)), ('x', 1))

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.
ORDER BY column OFFSET 0 ROWS
Surprisingly makes it work, what a strange feature.
A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:
;WITH cte AS (
SELECT .....long select statement here....
)
SELECT * FROM
(
SELECT * FROM
( -- necessary to nest selects for union to work with where & order clauses
SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS
) first
UNION ALL
SELECT * FROM
(
SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS
) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example
So we get all results ordered by MainCol
But the results with MainCol = 1
get ordered by ColX
And the results with MainCol = 0
get ordered by ColY
For completeness and correct resource management:
ICursor cursor = null;
try
{
cursor = db.RawQuery("SELECT * FROM " + RECORDS_TABLE + " WHERE " + RECORD_ID + "=?", new String[] { id + "" });
if (cursor.Count > 0)
{
cursor.MoveToFirst();
}
return GetRecordFromCursor(cursor); // Copy cursor props to custom obj
}
finally // IMPORTANT !!! Ensure cursor is not left hanging around ...
{
if(cursor != null)
cursor.Close();
}
I use Windows 7 Professional 64-bit and have both the 32-bit and 64-bit Java 7u9 jre's installed. Chrome refused to work until I deleted the following registry key.
HKEY_LOCAL_MACHINE/Software/MozillaPlugins/@java.com/DTPlugin,version=10.9.2
Then I refreshed Chrome and the Applet loaded with a Warning that the plugin was out of date. I seleted "Run this time" and everything worked as expected.
Normally it's done with a named Mutex (use new Mutex( "your app name", true ) and check the return value), but there's also some support classes in Microsoft.VisualBasic.dll that can do it for you.
If you want to have lists only when they are necessary, and values in any other cases, then you can do this:
class DictList(dict):
def __setitem__(self, key, value):
try:
# Assumes there is a list on the key
self[key].append(value)
except KeyError: # If it fails, because there is no key
super(DictList, self).__setitem__(key, value)
except AttributeError: # If it fails because it is not a list
super(DictList, self).__setitem__(key, [self[key], value])
You can then do the following:
dl = DictList()
dl['a'] = 1
dl['b'] = 2
dl['b'] = 3
Which will store the following {'a': 1, 'b': [2, 3]}
.
I tend to use this implementation when I want to have reverse/inverse dictionaries, in which case I simply do:
my_dict = {1: 'a', 2: 'b', 3: 'b'}
rev = DictList()
for k, v in my_dict.items():
rev_med[v] = k
Which will generate the same output as above: {'a': 1, 'b': [2, 3]}
.
CAVEAT: This implementation relies on the non-existence of the append
method (in the values you are storing). This might produce unexpected results if the values you are storing are lists. For example,
dl = DictList()
dl['a'] = 1
dl['b'] = [2]
dl['b'] = 3
would produce the same result as before {'a': 1, 'b': [2, 3]}
, but one might expected the following: {'a': 1, 'b': [[2], 3]}
.
In addition to the margins, the most common issue by far, I have also seen two additional possibilities:
+
to concatenate text. You should use &
instead.I was trying to select an area of svg with a rectangle and get all the elements from it. For this, element.getBoundingClientRect() worked perfectly for me. It returns current coordinates of svg elements regardless of whether svg is scaled or transformed.
Solution:
Add the below line in your application
tag:
android:usesCleartextTraffic="true"
As shown below:
<application
....
android:usesCleartextTraffic="true"
....>
UPDATE: If you have network security config such as: android:networkSecurityConfig="@xml/network_security_config"
No Need to set clear text traffic to true as shown above, instead use the below code:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
....
....
</domain-config>
<base-config cleartextTrafficPermitted="false"/>
</network-security-config>
Set the cleartextTrafficPermitted
to true
Hope it helps.

I was able to solve the problem by setting data-container="body"
on the html element
HTML
example:
<a href="#" data-toggle="tooltip" data-container="body" title="first tooltip">
hover over me
</a>
JavaScript
example:
$('your element').tooltip({ container: 'body' })
Discovered from this link: https://github.com/twitter/bootstrap/issues/5889
I based this solution on the comments of @jberger.
if git checkout master &&
git fetch origin master &&
[ `git rev-list HEAD...origin/master --count` != 0 ] &&
git merge origin/master
then
echo 'Updated!'
else
echo 'Not updated.'

You can use an anonymous function to pass the matches to your function:
$result = preg_replace_callback(
"/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
$result
);
Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e
would convert a double quote "
into \"
.
Try this:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
AlertDialog OptionDialog = builder.create();
background.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
SetBackground();
OptionDialog .dismiss();
}
});
Here is another way that I came up with: Let's say you want to get a float between 5.5 and 7, with 3 decimals.
float myFloat;
int myInt;
System.Random rnd = new System.Random();
void GenerateFloat()
{
myInt = rnd.Next(1, 2000);
myFloat = (myInt / 1000) + 5.5f;
}
That way you will always get a bigger number than 5.5 and a smaller number than 7.
Actually, you can also do it with the iteration method. Because sometimes we might need to use the iteration method instead of the built-in epochs method to visualize the training results after each iteration.
history = [] #Creating a empty list for holding the loss later
for iteration in range(1, 3):
print()
print('-' * 50)
print('Iteration', iteration)
result = model.fit(X, y, batch_size=128, nb_epoch=1) #Obtaining the loss after each training
history.append(result.history['loss']) #Now append the loss after the training to the list.
start_index = random.randint(0, len(text) - maxlen - 1)
print(history)
This way allows you to get the loss you want while maintaining your iteration method.
or in a better way we can have like this
Let's say your primary key is an Integer and object you save is "ticket", then you can get it like this. When you save the object, id is always returned
//unboxing will occur here so that id here will be value type not the reference type. Now you can check id for 0 in case of save failure. like below:
int id = (Integer) session.save(ticket);
if(id==0)
your session.save call was not success.
else '
your call to session.save was successful.
Kiran's answer is definetely the answer for my case.
In code part I split string to 4000 char strings and try to put them in to db.
Explodes with this error.
The cause of the error is using utf chars, those counts 2 bytes each. Even I truncate to 4000 chars in code(sth. like String.Take(4000)), oracle considers 4001 when string contains 'ö' or any other non-eng(non ascii to be precise, which are represented with two or bytes in utf8) characters.
The methodNotAllowed
exception indicates that a route doesn't exist for the HTTP method you are requesting.
Your form is set up to make a DELETE
request, so your route needs to use Route::delete()
to receive this.
Route::delete('empresas/eliminar/{id}', [
'as' => 'companiesDelete',
'uses' => 'CompaniesController@delete'
]);
The solution i'm using is as follows and allows you to set the active class per php page.
Give each of your menu items a unique class, i use .nav-x
(nav-about, here).
<li class="nav-item nav-about">
<a class="nav-link" href="about.php">About</a>
</li>
At the top of each page (about.php here):
<!-- Navbar Active Class -->
<?php $activeClass = '.nav-about > a'; ?>
Elsewhere (header.php / index.php):
<style>
<?php echo $activeClass; ?> {
color: #fff !important;
}
</style>
Simply change the .nav-about > a
per page, .nav-forum > a
, for example.
If you want different styling (colors etc) for each nav item, just attach the inline styling to that page instead of the index / header page.
make sure you push into an Array only and if their is error like Uncaught TypeError: data.push is not a function** then check for type of data you can do this by consol.log(data) hope this will help
It's as simple as iterating the array and looking for the regexp
function searchStringInArray (str, strArray) {
for (var j=0; j<strArray.length; j++) {
if (strArray[j].match(str)) return j;
}
return -1;
}
Edit - make str
as an argument to function.

Follow these:
choose the "Apache (httpd.conf)" and find this code below and change it into this one:
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 0.0.0.0:80
#Listen [::]:80
Listen 80
#
# Dynamic Shared Object (DSO) Support
save it (ctrl + s)
after that, go back to xampp control panel and click again its config
choose "Apache (httpd-ssl.conf)" find this code below and change it again:
# Note: Configurations that use IPv6 but not IPv4-mapped addresses need two
# Listen directives: "Listen [::]:443" and "Listen 0.0.0.0:443"
#
#Listen 0.0.0.0:443
#Listen [::]:443
Listen 443
save it (ctrl + s)
then, click the "config" (note: above the netstat) and click the "service and port settings" then save both of it.
finally, go to the "control panel" -> "Programs & Features" -> "Turn Windows On or Off".
Uncheck your "Internet Information Services" then click ok.
Just wait for it and your computer/laptop will be automatically restart and try to open again your xampp control panel then start your Apache.
The difference lies in whether mixing colours results in LIGHTER or DARKER colours. When mixing light, the result is a lighter colour, so mixing red light and blue light becomes a lighter pink. When mixing paint (or ink), red and blue become a darker purple. Mixing paint results in DARKER colours, whereas mixing light results in LIGHTER colours. Therefore for paint the primary colours are Red Yellow Blue (or Cyan Magenta Yellow) as you stated. Yet for light the primary colours are Red Green Blue. It is (virtually) impossible to mix Red Green Blue paint into Yellow paint, or mixing Red Yellow Blue light into Green light.
Turns out this could also be caused by BuildEvents. For me I was referencing $(SolutionDir) there. With a regular build this variable has value, but running dotnet * commands is done at project level apparently. $(SolutionDir) comes out like Undefined in verbose mode (-v). This seems like a bug to me.

If you're using npm >=1.0, you can use npm link <global-package>
to create a local link to a package already installed globally. (Caveat: The OS must support symlinks.)
However, this doesn't come without its problems.
npm link is a development tool. It's awesome for managing packages on your local development box. But deploying with npm link is basically asking for problems, since it makes it super easy to update things without realizing it.
As an alternative, you can install the packages locally as well as globally.
For additional information, see
Try:
bash -c '[ -d my_mystery_dirname ] && run_this_command'
This will work if you can run bash on the remote machine....
In bash, [ -d something ]
checks if there is directory called 'something', returning a success code if it exists and is a directory. Chaining commands with && runs the second command only if the first one succeeded. So [ -d somedir ] && command
runs the command only if the directory exists.
You can show/hide with Value or Class name. Check the below link with working example.
Show/hide jquery chosen options with value or with class name.
Use FilenameUtils.removeExtension
from Apache Commons IO
Example:
You can provide full path name or only the file name.
String myString1 = FilenameUtils.removeExtension("helloworld.exe"); // returns "helloworld"
String myString2 = FilenameUtils.removeExtension("/home/abc/yey.xls"); // returns "yey"
Hope this helps ..
If you want to simply output a date, just use the following:
System.out.printf("Date: %1$te/%1$tm/%1$tY at %1$tH:%1$tM:%1$tS%n", new Date());
As seen here. Or if you want to get the value into a String (for SQL building, for example) you can use:
String formattedDate = String.format("%1$te/%1$tm/%1$tY", new Date());
You can also customize your output by following the Java API on Date/Time conversions.
You can experiment with model.summary()
(notice the concatenate_XX (Concatenate) layer size)
# merge samples, two input must be same shape
inp1 = Input(shape=(10,32))
inp2 = Input(shape=(10,32))
cc1 = concatenate([inp1, inp2],axis=0) # Merge data must same row column
output = Dense(30, activation='relu')(cc1)
model = Model(inputs=[inp1, inp2], outputs=output)
model.summary()
# merge row must same column size
inp1 = Input(shape=(20,10))
inp2 = Input(shape=(32,10))
cc1 = concatenate([inp1, inp2],axis=1)
output = Dense(30, activation='relu')(cc1)
model = Model(inputs=[inp1, inp2], outputs=output)
model.summary()
# merge column must same row size
inp1 = Input(shape=(10,20))
inp2 = Input(shape=(10,32))

It is important to note that each jQuery()
call must actually return. If an exception is thrown in one, subsequent (unrelated) calls will never be executed.
This applies regardless of syntax. You can use jQuery()
, jQuery(function() {})
, $(document).ready()
, whatever you like, the behavior is the same. If an early one fails, subsequent blocks will never be run.
This was a problem for me when using 3rd-party libraries. One library was throwing an exception, and subsequent libraries never initialized anything.
You need to quote that values.
Here is a more detailed spec.
You can use the code below if you dont want to use jQuery UI or any third party pluggin. It's only plain jQuery.

This is a hairy one to answer, because you didn't give the full context of what you're doing. The accepted answer will work, but in some cases will cause poor performance. That, and it's going to be harder to test.
If you're doing this as part of a static form, fine. The accepted answer will work, even if it isn't easy to test, and it's hinky.
You'll want to keep any "business logic" (i.e. logic that alters data to be displayed) out of your views. This is so you can unit test your logic, and so you don't end up tightly coupling your controller and your view. Theoretically, you should be able to point your controller at another view and use the same values from the scopes. (if that makes sense).
You'll also want to consider that any function calls inside of a binding (such as {{}}
or ng-bind
or ng-bind-html
) will have to be evaluated on every digest, because angular has no way of knowing if the value has changed or not like it would with a property on the scope.
The "angular" way to do this would be to cache the value in a property on the scope on change using an ng-change event or even a $watch.
For example with a static form:
angular.controller('MainCtrl', function($scope, $window) {
$scope.count = 0;
$scope.total = 1;
$scope.updatePercentage = function () {
$scope.percentage = $window.Math.round((100 * $scope.count) / $scope.total);
};
});
<form name="calcForm">
<label>Count <input name="count" ng-model="count"
ng-change="updatePercentage()"
type="number" min="0" required/></label><br/>
<label>Total <input name="total" ng-model="total"
ng-change="updatePercentage()"
type="number" min="1" required/></label><br/>
<hr/>
Percentage: {{percentage}}
</form>
describe('Testing percentage controller', function() {
var $scope = null;
var ctrl = null;
//you need to indicate your module in a test
beforeEach(module('plunker'));
beforeEach(inject(function($rootScope, $controller) {
$scope = $rootScope.$new();
ctrl = $controller('MainCtrl', {
$scope: $scope
});
}));
it('should calculate percentages properly', function() {
$scope.count = 1;
$scope.total = 1;
$scope.updatePercentage();
expect($scope.percentage).toEqual(100);
$scope.count = 1;
$scope.total = 2;
$scope.updatePercentage();
expect($scope.percentage).toEqual(50);
$scope.count = 497;
$scope.total = 10000;
$scope.updatePercentage();
expect($scope.percentage).toEqual(5); //4.97% rounded up.
$scope.count = 231;
$scope.total = 10000;
$scope.updatePercentage();
expect($scope.percentage).toEqual(2); //2.31% rounded down.
});
});
I found a real cool Grid which I also use for columns. Check it out Simple Grid. Wich this CSS you can simply use:
<div class="grid">
<div class="col-1-2">
<div class="content">
<p>...insert content left side...</p>
</div>
</div>
<div class="col-1-2">
<div class="content">
<p>...insert content right side...</p>
</div>
</div>
</div>
I use it for all my projects.
As said by Sparky in comments on many answers to this question, there is NOT any textarea
value for the type
attribute of the input
tag.
On other terms, the following markup is not valid :
<input type="textarea" />
And the browser replaces it by the default :
<input type="text" />
To define a multi-lines text input, use :
<textarea></textarea>
See the textarea element documentation for more details.
Use the Microsoft "_countof(array)" Macro. This link to the Microsoft Developer Network explains it and offers an example that demonstrates the difference between "sizeof(array)" and the "_countof(array)" macro.
No, but you should be careful when using IF...ELSE...END IF in stored procs. If your code blocks are radically different, you may suffer from poor performance because the procedure plan will need to be re-cached each time. If it's a high-performance system, you may want to compile separate stored procs for each code block, and have your application decide which proc to call at the appropriate time.
The best way to check the instance of an object is through instanceof operator or with the method isPrototypeOf() which inspects if the prototype of an object is in another object's prototype chain.
obj instanceof jQuery;
jQuery.prototype.isPrototypeOf(obj);
But sometimes it might fail in the case of multiple jQuery instances on a document. As @Georgiy Ivankin mentioned:
if I have
$
in my current namespace pointing tojQuery2
and I have an object from outer namespace (where$
isjQuery1
) then I have no way to useinstanceof
for checking if that object is ajQuery
object
One way to overcome that problem is by aliasing the jQuery object in a closure or IIFE
//aliases jQuery as $
(function($, undefined) {
/*... your code */
console.log(obj instanceof $);
console.log($.prototype.isPrototypeOf(obj));
/*... your code */
}(jQuery1));
//imports jQuery1
Other way to overcome that problem is by inquiring the jquery
property in obj
'jquery' in obj
However, if you try to perform that checking with primitive values, it will throw an error, so you can modify the previous checking by ensuring obj
to be an Object
'jquery' in Object(obj)
Although the previous way is not the safest (you can create the 'jquery'
property in an object), we can improve the validation by working with both approaches:
if (obj instanceof jQuery || 'jquery' in Object(obj)) { }
The problem here is that any object can define a property jquery
as own, so a better approach would be to ask in the prototype, and ensure that the object is not null
or undefined
if (obj && (obj instanceof jQuery || obj.constructor.prototype.jquery)) { }
Due to coercion, the if
statement will make short circuit by evaluating the &&
operator when obj
is any of the falsy values (null
, undefined
, false
, 0
, ""
), and then proceeds to perform the other validations.
Finally we can write an utility function:
function isjQuery(obj) {
return (obj && (obj instanceof jQuery || obj.constructor.prototype.jquery));
}
Let's take a look at: Logical Operators and truthy / falsy
