The bitmap constructor has resizing built in.
Bitmap original = (Bitmap)Image.FromFile("DSC_0002.jpg");
Bitmap resized = new Bitmap(original,new Size(original.Width/4,original.Height/4));
resized.Save("DSC_0002_thumb.jpg");

It's 2020 and many of these answers no longer apply to the Sequelize v4/v5/v6 ecosystem.
The one good answer says to use sequelize-auto-migrations
, but probably is not prescriptive enough to use in your project. So here's a bit more color...
My team uses a fork of sequelize-auto-migrations
because the original repo is has not been merged a few critical PRs. #56 #57 #58 #59
$ yarn add github:scimonster/sequelize-auto-migrations#a063aa6535a3f580623581bf866cef2d609531ba
Edit package.json:
"scripts": {
...
"db:makemigrations": "./node_modules/sequelize-auto-migrations/bin/makemigration.js",
...
}
Note: Make sure you’re using git (or some source control) and database backups so that you can undo these changes if something goes really bad.
.sync()
yarn db:makemigrations --name "mega-migration"
).01-mega-migration.js
and the _current.json
that is generated..sync()
or hand-written migrations, you need to “Fake” that mega-migration by inserting the name of it into your SequelizeMeta table. INSERT INTO SequelizeMeta Values ('01-mega-migration.js')
.$ yarn db:makemigrations --name whatever
02-whatever.js
migration and the changes to _current.json
, and _current.bak.json
.$ yarn sequelize db:migrate
.removeColumn
and addColumn
. This will lose data in production. You will need to modify the up and down actions to use renameColumn
instead.For those who confused how to use
renameColumn
, the snippet would look like this. (switch "column_name_before" and "column_name_after" for therollbackCommands
)
{
fn: "renameColumn",
params: [
"table_name",
"column_name_before",
"column_name_after",
{
transaction: transaction
}
]
}
If you have a lot of migrations, the down action may not perfectly remove items in an order consistent way.
The maintainer of this library does not actively check it. So if it doesn't work for you out of the box, you will need to find a different community fork or another solution.
To check if a string is empty or contains only whitespace you could use:
shopt -s extglob # more powerful pattern matching
if [ -n "${str##+([[:space:]])}" ]; then
echo '$str is not null or space'
fi
See Shell Parameter Expansion and Pattern Matching in the Bash Manual.
Try this:
foreach($samplearr as $key => $item){
print "<tr><td>"
. $key
. "</td><td>"
. $item['value1']
. "</td><td>"
. $item['value2']
. "</td></tr>";
}
Another short version:
System.IO.File.WriteAllBytes(path, new byte[0]);
$('.second').find('div:first')
Use the -O file
option.
E.g.
wget google.com
...
16:07:52 (538.47 MB/s) - `index.html' saved [10728]
vs.
wget -O foo.html google.com
...
16:08:00 (1.57 MB/s) - `foo.html' saved [10728]
I know this question already has an accepted answer, but for me, a .NET beginner, there was a simple solution to what I was doing wrong and I thought I'd share.
I had been doing this:
@Html.HiddenFor(Model.Foo.Bar.ID)
What worked for me was changing to this:
@Html.HiddenFor(m => m.Foo.Bar.ID)
(where "m" is an arbitrary string to represent the model object)
children
const Wrapper = ({children}) => (
<div>
<div>header</div>
<div>{children}</div>
<div>footer</div>
</div>
);
const App = ({name}) => <div>Hello {name}</div>;
const WrappedApp = ({name}) => (
<Wrapper>
<App name={name}/>
</Wrapper>
);
render(<WrappedApp name="toto"/>,node);
This is also known as transclusion
in Angular.
children
is a special prop in React and will contain what is inside your component's tags (here <App name={name}/>
is inside Wrapper
, so it is the children
Note that you don't necessarily need to use children
, which is unique for a component, and you can use normal props too if you want, or mix props and children:
const AppLayout = ({header,footer,children}) => (
<div className="app">
<div className="header">{header}</div>
<div className="body">{children}</div>
<div className="footer">{footer}</div>
</div>
);
const appElement = (
<AppLayout
header={<div>header</div>}
footer={<div>footer</div>}
>
<div>body</div>
</AppLayout>
);
render(appElement,node);
This is simple and fine for many usecases, and I'd recommend this for most consumer apps.
It is possible to pass render functions to a component, this pattern is generally called render prop
, and the children
prop is often used to provide that callback.
This pattern is not really meant for layout. The wrapper component is generally used to hold and manage some state and inject it in its render functions.
Counter example:
const Counter = () => (
<State initial={0}>
{(val, set) => (
<div onClick={() => set(val + 1)}>
clicked {val} times
</div>
)}
</State>
);
You can get even more fancy and even provide an object
<Promise promise={somePromise}>
{{
loading: () => <div>...</div>,
success: (data) => <div>{data.something}</div>,
error: (e) => <div>{e.message}</div>,
}}
</Promise>
Note you don't necessarily need to use children
, it is a matter of taste/API.
<Promise
promise={somePromise}
renderLoading={() => <div>...</div>}
renderSuccess={(data) => <div>{data.something}</div>}
renderError={(e) => <div>{e.message}</div>}
/>
As of today, many libraries are using render props (React context, React-motion, Apollo...) because people tend to find this API more easy than HOC's. react-powerplug is a collection of simple render-prop components. react-adopt helps you do composition.
const wrapHOC = (WrappedComponent) => {
class Wrapper extends React.PureComponent {
render() {
return (
<div>
<div>header</div>
<div><WrappedComponent {...this.props}/></div>
<div>footer</div>
</div>
);
}
}
return Wrapper;
}
const App = ({name}) => <div>Hello {name}</div>;
const WrappedApp = wrapHOC(App);
render(<WrappedApp name="toto"/>,node);
An Higher-Order Component / HOC is generally a function that takes a component and returns a new component.
Using an Higher-Order Component can be more performant than using children
or render props
, because the wrapper can have the ability to short-circuit the rendering one step ahead with shouldComponentUpdate
.
Here we are using PureComponent
. When re-rendering the app, if the WrappedApp
name prop does not change over time, the wrapper has the ability to say "I don't need to render because props (actually, the name) are the same as before". With the children
based solution above, even if the wrapper is PureComponent
, it is not the case because the children element is recreated everytime the parent renders, which means the wrapper will likely always re-render, even if the wrapped component is pure. There is a babel plugin that can help mitigate this and ensure a constant children
element over time.
Higher-Order Components can give you better performance. It's not so complicated but it certainly looks unfriendly at first.
Don't migrate your whole codebase to HOC after reading this. Just remember that on critical paths of your app you might want to use HOCs instead of runtime wrappers for performance reasons, particularly if the same wrapper is used a lot of times it's worth considering making it an HOC.
Redux used at first a runtime wrapper <Connect>
and switched later to an HOC connect(options)(Comp)
for performance reasons (by default, the wrapper is pure and use shouldComponentUpdate
). This is the perfect illustration of what I wanted to highlight in this answer.
Note if a component has a render-prop API, it is generally easy to create a HOC on top of it, so if you are a lib author, you should write a render prop API first, and eventually offer an HOC version. This is what Apollo does with <Query>
render-prop component, and the graphql
HOC using it.
Personally, I use both, but when in doubt I prefer HOCs because:
compose(hoc1,hoc2)(Comp)
) compared to render propsI don't hesitate to use/create HOC versions of my favorite tools:
Context.Consumer
compSubscribe
graphql
HOC of Apollo instead of Query
render propIn my opinion, sometimes render props make the code more readable, sometimes less... I try to use the most pragmatic solution according to the constraints I have. Sometimes readability is more important than performances, sometimes not. Choose wisely and don't bindly follow the 2018 trend of converting everything to render-props.
After much digging around we were able to scrape the info more or less (mainly from Keycloak's own JS client lib):
/auth/realms/{realm}/tokens/login
/auth/realms/{realm}/tokens/access/codes
As for OpenID Connect UserInfo, right now (1.1.0.Final) Keycloak doesn't implement this endpoint, so it is not fully OpenID Connect compliant. However, there is already a patch that adds that as of this writing should be included in 1.2.x.
But - Ironically Keycloak does send back an id_token
in together with the access token. Both the id_token
and the access_token
are signed JWTs, and the keys of the token are OpenID Connect's keys, i.e:
"iss": "{realm}"
"sub": "5bf30443-0cf7-4d31-b204-efd11a432659"
"name": "Amir Abiri"
"email: "..."
So while Keycloak 1.1.x is not fully OpenID Connect compliant, it does "speak" in OpenID Connect language.
Or you can do this way :
((TextView)findViewById(R.id.this_is_the_id_of_textview)).setText("Test");
NOTE: For a concise and efficient solution, please see Marc-André Lafortune's answer below.
This answer was originally offered as an alternative to approaches using flatten, which were the most highly upvoted at the time of writing. I should have clarified that I didn't intend to present this example as a best practice or an efficient approach. Original answer follows.
Warning! Solutions using flatten will not preserve Array keys or values!
Building on @John Topley's popular answer, let's try:
a3 = [ ['apple', 1], ['banana', 2], [['orange','seedless'], 3] ]
h3 = Hash[*a3.flatten]
This throws an error:
ArgumentError: odd number of arguments for Hash
from (irb):10:in `[]'
from (irb):10
The constructor was expecting an Array of even length (e.g. ['k1','v1,'k2','v2']). What's worse is that a different Array which flattened to an even length would just silently give us a Hash with incorrect values.
If you want to use Array keys or values, you can use map:
h3 = Hash[a3.map {|key, value| [key, value]}]
puts "h3: #{h3.inspect}"
This preserves the Array key:
h3: {["orange", "seedless"]=>3, "apple"=>1, "banana"=>2}
Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.
from datetime import datetime
from time import mktime
dt = datetime.fromtimestamp(mktime(struct))
in my case
@JsonInclude(Include.NON_EMPTY)
made it work.
Async/Await with axios
useEffect(() => {
const getData = async () => {
await axios.get('your_url')
.then(res => {
console.log(res)
})
.catch(err => {
console.log(err)
});
}
getData()
}, [])
Just to clarify what yalestar said, this will give you the relative path:
Workbooks.Open FileName:= ThisWorkbook.Path & "\TRICATEndurance Summary.html"
You can open a new popup window by following code:
var myWindow = window.open("", "newWindow", "width=500,height=700");
//window.open('url','name','specs');
Afterwards, you can add HTML using both myWindow.document.write();
or myWindow.document.body.innerHTML = "HTML";
What I will recommend is that first you create a new html file with any name. In this example I am using
newFile.html
And make sure to add all content in that file such as bootstrap cdn or jquery, means all the links and scripts. Then make a div with some id or use your body and give that a id
. in this example I have given id="mainBody"
to my newFile.html <body>
tag
<body id="mainBody">
Then open this file using
<script>
var myWindow = window.open("newFile.html", "newWindow", "width=500,height=700");
</script>
And add whatever you want to add in your body tag. using following code
<script>
var myWindow = window.open("newFile.html","newWindow","width=500,height=700");
myWindow.onload = function(){
let content = "<button class='btn btn-primary' onclick='window.print();'>Confirm</button>";
myWindow.document.getElementById('mainBody').innerHTML = content;
}
myWindow.window.close();
</script>
it is as simple as that.

window.location
always refers to the location of the current window. Changing it will affect only the current window.
One thing that can be done is forcing a click on the link after setting its target
attribute to _blank
:
Check this: http://www.techfoobar.com/2012/jquery-programmatically-clicking-a-link-and-forcing-the-default-action
Disclaimer: Its my blog.
See the isDigit(char ch)
method:
https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Character.html
and pass it to the first character of the String using the String.charAt()
method.
Character.isDigit(myString.charAt(0));
Try this, it's shorter and works exactly as window.location.href
:
if (document.URL.indexOf("franky") > -1) { ... }
also if you want to check the previous URL:
if (document.referrer.indexOf("franky") > -1) { ... }
Your expression is never going to evaluate.
You are comparing a
with a property of a
.
a
is of type Answer. a.Correct
, I'm guessing is a boolean.
Long form:-
Answer = answer.SingleOrDefault(a => a.Correct == true);
Short form:-
Answer = answer.SingleOrDefault(a => a.Correct);
You can read files in raw/res using getResources().openRawResource(R.raw.myfilename)
.
BUT there is an IDE limitation that the file name you use can only contain lower case alphanumeric characters and dot. So file names like XYZ.txt
or my_data.bin
will not be listed in R.
GridView
is used for implementing material grid lists. If you know you have a fixed number of items and it's not very many (16 is fine), you can use GridView.count
. However, you should note that a GridView
is scrollable, and if that isn't what you want, you may be better off with just rows and columns.

('a', 'b', 'c', 'd')

True
When unpacking into two lists, this becomes:
>>> list1, list2 = zip(*source_list)
>>> list(source_list) == zip(list1, list2)
True
Addition suggested by rocksportrocker.
The other answers are right. Assuming your examples reflect the full range of possibilities what you want is DECIMAL(3, 1)
. Or, DECIMAL(14, 1)
will allow a total of 14 digits. It's your job to think about what's enough.
I found if you have issues with including or mixing your page with something like http://www.example.com, you can fix that by putting //www.example.com instead

I performed tests on Eclipse vs Netbeans 8.0.2, both with Java version 1.8;
I used System.nanoTime()
for measurements.
I got the same time on both cases - around 1.564 seconds.
So, it looks like Netbeans has bad performance on print to console.
After more research I realized that the problem is line-wrapping of the max buffer of Netbeans (it's not restricted to System.out.println
command), demonstrated by this code:
for (int i = 0; i < 1000; i++) {
long t1 = System.nanoTime();
System.out.print("BBB......BBB"); \\<-contain 1000 "B"
long t2 = System.nanoTime();
System.out.println(t2-t1);
System.out.println("");
}
The time results are less then 1 millisecond every iteration except every fifth iteration, when the time result is around 225 millisecond. Something like (in nanoseconds):
BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807
BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807
.
.
.
And so on..
you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment
<div style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: gray;height:30px;">
<div style="float:left;line-height:30px;">Contact Details</div>
<button type="button" class="edit_button" style="float: right;">My Button</button>
</div>

We can also use this to update multiple documents.
You could get a JavaScript object containing the parameters with something like this:
var regex = /[?&]([^=#]+)=([^&#]*)/g,
url = window.location.href,
params = {},
match;
while(match = regex.exec(url)) {
params[match[1]] = match[2];
}
The regular expression could quite likely be improved. It simply looks for name-value pairs, separated by =
characters, and pairs themselves separated by &
characters (or an =
character for the first one). For your example, the above would result in:
{v: "123", p: "hello"}
Here's a working example.
There could be any of the following, but all of them lead into DOM not loaded before its accessed by the javascript.
So here is what you have to ensure before actually calling JS code: * Make sure the container has loaded before any javascript is called * Make sure the target URL is loaded in whatever container it has to
I came across the similar issue but on my local when I am trying to have my Javascript run well before onLoad of the main page which causes the error message. I have fixed it by simply waiting for whole page to load and then call the required function.
You could simply do this by adding a timeout function when page has loaded and call your onload event like:
window.onload = new function() { setTimeout(function() { // some onload event }, 10); }
that will ensure what you are trying will execute well after onLoad is trigger.
If your application uses async stuff and you're fiddling with Mouse's cursor, you probably want to do it only in main UI thread. You can use app's Dispatcher thread for that:
Application.Current.Dispatcher.Invoke(() =>
{
// The check is required to prevent cursor flickering
if (Mouse.OverrideCursor != cursor)
Mouse.OverrideCursor = cursor;
});
With the magic of user-defined literals, we have yet another solution to this. C++14 added a std::string
literal operator.
using namespace std::string_literals;
auto const x = "\0" "0"s;
Constructs a string of length 2, with a '\0' character (null) followed by a '0' character (the digit zero). I am not sure if it is more or less clear than the initializer_list<char>
constructor approach, but it at least gets rid of the '
and ,
characters.
This is now supported in Chrome by the "Pause on all exceptions" button.
To enable it:
Note that this button has multiple states. Keep clicking the button to switch between
One gotcha to do with converting Base64 from a string is that some conversion functions use the preceding "data:image/jpg;base64," and others only accept the actual data.
You need a dependency property for this:
public BindingList<User> Users
{
get { return (BindingList<User>)GetValue(UsersProperty); }
set { SetValue(UsersProperty, value); }
}
public static readonly DependencyProperty UsersProperty =
DependencyProperty.Register("Users", typeof(BindingList<User>),
typeof(OptionsDialog));
Once that is done, you bind the checkbox to the dependency property:
<CheckBox x:Name="myCheckBox"
IsChecked="{Binding ElementName=window1, Path=CheckBoxIsChecked}" />
For that to work you have to name your Window or UserControl in its openning tag, and use that name in the ElementName parameter.
With this code, whenever you change the property on the code side, you will change the textbox. Also, whenever you check/uncheck the textbox, the Dependency Property will change too.
EDIT:
An easy way to create a dependency property is typing the snippet propdp, which will give you the general code for Dependency Properties.

public static readonly DependencyProperty IsCheckBoxCheckedProperty =

Notice how the only code behind is the Dependency Property. Both the label and the checkbox are bound to it. If the checkbox changes, the label changes too.

You can simply use
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('body,html').animate({
scrollTop: 0
}, 800);
$('#btn-go-to-top').click(function () {
$('body,html').animate({
scrollTop: 0
}, 800);
return false;
});
});
</script>
this will help you to smoothly scroll to the top of the page.
and for styling
#btn-go-to-top {
opacity: .5;
width:4%;
height:8%;
display: none;
position: fixed;
bottom: 5%;
right: 3%;
z-index: 99;
border: none;
outline: none;
background-color: red;
color: white;
cursor: pointer;
padding: 10px;
border-radius: 50%;
}
#btn-go-to-top:hover {
opacity: 1;
}
.top {
transition: all 0.5s ease 0s;
-moz-transition: all 0.5s ease 0s;
-webkit-transition: all 0.5s ease 0s;
-o-transition: all 0.5s ease 0s;
}
this styling makes the button arrive at the bottom-right of the page.
and in your page you can add the button to go to top like this
<div id="btn-go-to-top" class="text-center top">
<img src="uploads/Arrow.png" style="margin: 7px;" width="50%" height="50%">
</div>
hope this help you.if you have any doubts you are always free to ask me
In Java 11 we can use Collection.toArray(generator)
method. The following code will create a new array of String:
Set<String> set = Set.of("one", "two", "three");
String[] array = set.toArray(String[]::new)
I prefer to use java.util.Scanner
:
try {
Scanner scanner = new Scanner(context.openFileInput(filename)).useDelimiter("\\Z");
StringBuilder sb = new StringBuilder();
while (scanner.hasNext()) {
sb.append(scanner.next());
}
scanner.close();
String result = sb.toString();
} catch (IOException e) {}
The best definition I've found so far is one by James Shore:
"Dependency Injection" is a 25-dollar term for a 5-cent concept. [...] Dependency injection means giving an object its instance variables. [...].
There is an article by Martin Fowler that may prove useful, too.
Dependency injection is basically providing the objects that an object needs (its dependencies) instead of having it construct them itself. It's a very useful technique for testing, since it allows dependencies to be mocked or stubbed out.
Dependencies can be injected into objects by many means (such as constructor injection or setter injection). One can even use specialized dependency injection frameworks (e.g. Spring) to do that, but they certainly aren't required. You don't need those frameworks to have dependency injection. Instantiating and passing objects (dependencies) explicitly is just as good an injection as injection by framework.

Here's an example that reads a list of CSV strings into a list of lists and then loops through that list of lists and prints the CSV strings back out to the console.
import java.util.ArrayList;
import java.util.List;
public class ListExample
{
public static void main(final String[] args)
{
//sample CSV strings...pretend they came from a file
String[] csvStrings = new String[] {
"abc,def,ghi,jkl,mno",
"pqr,stu,vwx,yz",
"123,345,678,90"
};
List<List<String>> csvList = new ArrayList<List<String>>();
//pretend you're looping through lines in a file here
for(String line : csvStrings)
{
String[] linePieces = line.split(",");
List<String> csvPieces = new ArrayList<String>(linePieces.length);
for(String piece : linePieces)
{
csvPieces.add(piece);
}
csvList.add(csvPieces);
}
//write the CSV back out to the console
for(List<String> csv : csvList)
{
//dumb logic to place the commas correctly
if(!csv.isEmpty())
{
System.out.print(csv.get(0));
for(int i=1; i < csv.size(); i++)
{
System.out.print("," + csv.get(i));
}
}
System.out.print("\n");
}
}
}
Pretty straightforward I think. Just a couple points to notice:
I recommend using "List" instead of "ArrayList" on the left side when creating list objects. It's better to pass around the interface "List" because then if later you need to change to using something like Vector (e.g. you now need synchronized lists), you only need to change the line with the "new" statement. No matter what implementation of list you use, e.g. Vector or ArrayList, you still always just pass around List<String>
.
In the ArrayList constructor, you can leave the list empty and it will default to a certain size and then grow dynamically as needed. But if you know how big your list might be, you can sometimes save some performance. For instance, if you knew there were always going to be 500 lines in your file, then you could do:
List<List<String>> csvList = new ArrayList<List<String>>(500);
That way you would never waste processing time waiting for your list to grow dynamically grow. This is why I pass "linePieces.length" to the constructor. Not usually a big deal, but helpful sometimes.
Hope that helps!
you can use 'use' in function like bellow example
function page_properties($objPortal) use($objPage){
$objPage->set_page_title($myrow['title']);
}
def updateJsonFile():
jsonFile = open("replayScript.json", "r") # Open the JSON file for reading
data = json.load(jsonFile) # Read the JSON into the buffer
jsonFile.close() # Close the JSON file
## Working with buffered content
tmp = data["location"]
data["location"] = path
data["mode"] = "replay"
## Save our changes to JSON file
jsonFile = open("replayScript.json", "w+")
jsonFile.write(json.dumps(data))
jsonFile.close()
This would be the shortest way to sum up int
type array (for long
array LongStream
, for double
array DoubleStream
and so forth). Not all the primitive integer or floating point types have the Stream
implementation though.
IntStream.of(integers).sum();
Try swich fetchType from LAZY to EAGER
...
@OneToMany(fetch=FetchType.EAGER)
private Set<NodeValue> nodeValues;

But in this case your app will fetch data from DB anyway. If this query very hard - this may impact on performance. More here: https://docs.oracle.com/javaee/6/api/javax/persistence/FetchType.html

In case someone is using php7 under a Linux environment
Make sure you enable php7
sudo a2enmod php7
Restart the mysql service and Apache
sudo systemctl restart mysql
sudo systemctl restart apache2
Consider using Android's uiautomator, with adb shell uiautomator [...] or directly using the .jar that comes with the SDK.
For this particular case, if using re
module is overkill, how about using split
(or rsplit
) method as
se='</html>'
z.write(article.split(se)[0]+se)
For example,
#!/usr/bin/python
article='''<html>Larala
Ponta Monta
</html>Kurimon
Waff Moff
'''
z=open('out.txt','w')
se='</html>'
z.write(article.split(se)[0]+se)
outputs out.txt
as
<html>Larala
Ponta Monta
</html>
I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:
function utf8_to_latin2($str)
{
return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
{
mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
"From: $form\r\n".
"Reply-To: $reply\r\n".
"X-Mailer: PHP/" . phpversion());
}
I have made another mailer function, because apple device could not read well the previous version.
function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
$s= "=?utf-8?b?".base64_encode($s)."?=";
$headers = "MIME-Version: 1.0\r\n";
$headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
$headers.= "Content-Type: text/plain;charset=utf-8\r\n";
$headers.= "Reply-To: $reply\r\n";
$headers.= "X-Mailer: PHP/" . phpversion();
mail($to, $s, $body, $headers);
}
You should use Event Delegation, because of the fact that you are creating dynamic rows.
$(document).on('click','button.removebutton', function() {
alert("aa");
$(this).closest('tr').remove();
return false;
});
If you're using php7 and you want to handle only undefined errors this is the cleanest IMHO
$array = [1,2,3,4];
foreach ( $array ?? [] as $item ) {
echo $item;
}

With help from numpy one can calculate for example a linear fitting.
# plot the data itself
pylab.plot(x,y,'o')
# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])
The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.
You can also split a string at every n-th character and put them each, in each index of a List :
Here I made a list of Strings named Sequence :
List < String > Sequence
Then I'm basically splitting the String "KILOSO" by every 2 words. So 'KI' 'LO' 'SO' would be incorporate in separate index of the List called Sequence.
String S = KILOSO
Sequence = Arrays.asList(S.split("(?<=\G..)"));
So when I'm doing :
System.out.print(Sequence)
It should print :
[KI, LO, SO]
to verify I can write :
System.out.print(Sequence.get(1))
it will print :
LO

I faced this Issue multiple times and they're all solved by disabling Instant Run.
I know this is an old question, but it is the top google result for "gitbash homedir windows" so figured I'd add my findings.
No matter what I tried I couldn't get git-bash to start in anywhere but my network drive,(U:) in my case making every operation take 15-20 seconds to respond. (Remote employee on VPN, network drive hosted on the other side of the country)
I tried setting HOME and HOMEDIR variables in windows.
I tried setting HOME and HOMEDIR variables in the git installation'setc/profile file.
I tried editing the "Start in" on the git-bash shortcut to be C:/user/myusername.
"env" command inside the git-bash shell would show correct c:/user/myusername. But git-bash would still start in U:
What ultimately fixed it for me was editing the git-bash shortcut and removing the "--cd-to-home" from the Target line.
I'm on Windows 10 running latest version of Git-for-windows 2.22.0.
You would just do the same thing, looping through the array to search for the term you want. Of course if it's a sorted array this would be much faster, so something similar to prehaps:
for(int i = 0; i < arraySize; i++){
if(array[i] == itemToFind){
break;
}
}
Normaly you can GET and POST parameters in a servlet the same way:
request.getParameter("cmd");
But only if the POST data is encoded as key-value pairs of content type: "application/x-www-form-urlencoded" like when you use a standard HTML form.
If you use a different encoding schema for your post data, as in your case when you post a json data stream, you need to use a custom decoder that can process the raw datastream from:
BufferedReader reader = request.getReader();
Json post processing example (uses org.json package )
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
StringBuffer jb = new StringBuffer();
String line = null;
try {
BufferedReader reader = request.getReader();
while ((line = reader.readLine()) != null)
jb.append(line);
} catch (Exception e) { /*report an error*/ }
try {
JSONObject jsonObject = HTTP.toJSONObject(jb.toString());
} catch (JSONException e) {
// crash and burn
throw new IOException("Error parsing JSON request string");
}
// Work with the data using methods like...
// int someInt = jsonObject.getInt("intParamName");
// String someString = jsonObject.getString("stringParamName");
// JSONObject nestedObj = jsonObject.getJSONObject("nestedObjName");
// JSONArray arr = jsonObject.getJSONArray("arrayParamName");
// etc...
}
To avoid memory leaks you may use smart pointers whenever you can. There are basically 2 different types of smart pointers in C++
The main difference is that reference counted smart pointers can be copied (and used in std:: containers) while scoped_ptr cannot. Non reference counted pointers have almost no overhead or no overhead at all. Reference counting always introduces some kind of overhead.
(I suggest to avoid auto_ptr, it has some serious flaws if used incorrectly)
If your project is Maven-based, remember to set scope to provided for such dependencies as servlet-api, jsp-api. Otherwise, these jars will be exported to WEB-INF/lib and hence contaminate with those in Tomcat server. That causes painful problems.

since HashMap
implements Serializable
interface, you can simply use ObjectOutputStream
class to write whole Map
to file, and read it again using ObjectInputStream
class
below simple code that explain usage of ObjectOutStream
and ObjectInputStream
import java.util.*;
import java.io.*;
public class A{
HashMap<String,String> hm;
public A() {
hm=new HashMap<String,String>();
hm.put("1","A");
hm.put("2","B");
hm.put("3","C");
method1(hm);
}
public void method1(HashMap<String,String> map) {
//write to file : "fileone"
try {
File fileOne=new File("fileone");
FileOutputStream fos=new FileOutputStream(fileOne);
ObjectOutputStream oos=new ObjectOutputStream(fos);
oos.writeObject(map);
oos.flush();
oos.close();
fos.close();
} catch(Exception e) {}
//read from file
try {
File toRead=new File("fileone");
FileInputStream fis=new FileInputStream(toRead);
ObjectInputStream ois=new ObjectInputStream(fis);
HashMap<String,String> mapInFile=(HashMap<String,String>)ois.readObject();
ois.close();
fis.close();
//print All data in MAP
for(Map.Entry<String,String> m :mapInFile.entrySet()){
System.out.println(m.getKey()+" : "+m.getValue());
}
} catch(Exception e) {}
}
public static void main(String args[]) {
new A();
}
}
or if you want to write data as text to file you can simply iterate through Map
and write key and value line by line, and read it again line by line and add to HashMap
import java.util.*;
import java.io.*;
public class A{
HashMap<String,String> hm;
public A(){
hm=new HashMap<String,String>();
hm.put("1","A");
hm.put("2","B");
hm.put("3","C");
method2(hm);
}
public void method2(HashMap<String,String> map) {
//write to file : "fileone"
try {
File fileTwo=new File("filetwo.txt");
FileOutputStream fos=new FileOutputStream(fileTwo);
PrintWriter pw=new PrintWriter(fos);
for(Map.Entry<String,String> m :map.entrySet()){
pw.println(m.getKey()+"="+m.getValue());
}
pw.flush();
pw.close();
fos.close();
} catch(Exception e) {}
//read from file
try {
File toRead=new File("filetwo.txt");
FileInputStream fis=new FileInputStream(toRead);
Scanner sc=new Scanner(fis);
HashMap<String,String> mapInFile=new HashMap<String,String>();
//read data from file line by line:
String currentLine;
while(sc.hasNextLine()) {
currentLine=sc.nextLine();
//now tokenize the currentLine:
StringTokenizer st=new StringTokenizer(currentLine,"=",false);
//put tokens ot currentLine in map
mapInFile.put(st.nextToken(),st.nextToken());
}
fis.close();
//print All data in MAP
for(Map.Entry<String,String> m :mapInFile.entrySet()) {
System.out.println(m.getKey()+" : "+m.getValue());
}
}catch(Exception e) {}
}
public static void main(String args[]) {
new A();
}
}

I'm using GitHub for Windows which is a nice visual option. But I also prefer the command line, so to make it work when I open a repository in a Git shell I just set the following:
git config --global core.editor vim
which works great.
You can also do this without cat
, though honestly cat
is more readable:
>> file1 < file2
The >>
appends STDIN to file1
and the <
dumps file2
to STDIN.

setTimeout(callback,t)
is used to run callback after at least t millisecond. The actual delay depends on many external factors like OS timer granularity and system load.
So, there is a possibility that it will be called slightly after the set time, but will never be called before.
A timer can't span more than 24.8 days.

Following will work like a charm (assuming you have div/span/table/tr/td/etc with "id"="myId"
)
$("#myId").hover(function() {
$(this).css('cursor','pointer').attr('title', 'This is a hover text.');
}, function() {
$(this).css('cursor','auto');
});
As a complimentary, .css('cursor','pointer')
will change the mouse pointer on hover.
Using a normal css selector:
$('.sys input[type=text], .sys select').each(function() {...})
If you don't like the repetition:
$('.sys').find('input[type=text],select').each(function() {...})
Or more concisely, pass in the context
argument:
$('input[type=text],select', '.sys').each(function() {...})
Note: Internally jQuery
will convert the above to find()
equivalent
Internally, selector context is implemented with the .find() method, so $('span', this) is equivalent to $(this).find('span').
I personally find the first alternative to be the most readable :), your take though
The ALTER TABLE
MySQL command should do the trick. The following command will change the default character set of your table and the character set of all its columns to UTF8.
ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
This command will convert all text-like columns in the table to the new character set. Character sets use different amounts of data per character, so MySQL will convert the type of some columns to ensure there's enough room to fit the same number of characters as the old column type.
I recommend you read the ALTER TABLE MySQL documentation before modifying any live data.
I think the easiest way to accomplish it is to use querystring instead of HTTP headers.

Here are some schemes the Facebook app uses, there are a ton more on the source link:
NSURL *url = [NSURL URLWithString:@"fb://profile/<id>"];
[[UIApplication sharedApplication] openURL:url];
fb://profile – Open Facebook app to the user’s profile
fb://friends – Open Facebook app to the friends list
fb://notifications – Open Facebook app to the notifications list (NOTE: there appears to be a bug with this URL. The Notifications page opens. However, it’s not possible to navigate to anywhere else in the Facebook app)
fb://feed – Open Facebook app to the News Feed
fb://events – Open Facebook app to the Events page
fb://requests – Open Facebook app to the Requests list
fb://notes – Open Facebook app to the Notes page
fb://albums – Open Facebook app to Photo Albums list
If before opening this url you want to check wether the user fas the facebook app you can do the following (as explained in another answer below):
if ([[UIApplication sharedApplication] canOpenURL:nsurl]){
[[UIApplication sharedApplication] openURL:nsurl];
}
else {
//Open the url as usual
}

At work we have a common library that is used by a few different projects all in a single repository. Originally we used the published (private) version (npm install --save rp-utils) but that lead to a lot of needless version updates as we developed. The library lives in a sister directory to the applications and we are able to use a relative path instead of a version. Instead of "rp-utils": "^1.3.34" in package.json it now is:
{
"dependencies": { ...
"rp-utils": "../rp-utils",
...
the rp-utils directory contains a publishable npm package

Using the utility I describe here, you can have a more control over the string representation you get for your array.
String[] s = { "hello", "world" };
RichIterable<String> r = RichIterable.from(s);
r.mkString(); // gives "hello, world"
r.mkString(" | "); // gives "hello | world"
r.mkString("< ", ", ", " >"); // gives "< hello, world >"
You still have to wrap it in an ISERROR, but you could use MATCH()
instead of VLOOKUP()
:
Returns the relative position of an item in an array that matches a specified value in a specified order. Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself.
Here's a complete example, assuming you're looking for the word "key" in a range of cells:
=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")
The FALSE
is necessary to force an exact match, otherwise it will look for the closest value.

You can use Chocolatey to install cyg-get
and then install your packages with it.
For example:
choco install cyg-get
Then:
cyg-get install my-package
Here is a different solution for anyone interested. It uses the new For range in c++11
string str("(555) 555-5555");
string str2="";
for (const auto c: str){
if(!ispunct(c)){
str2.push_back(c);
}
}
str = str2;
//output: 555 5555555
cout<<str<<endl;
This question is similar to How do I limit the number of rows returned by an Oracle query after ordering?.
It talks about how to implement a MySQL limit on an oracle database which judging by your tags and post is what you are using.
The relevant section is:
select *
from
( select *
from emp
order by sal desc )
where ROWNUM <= 5;
hg strip
is what you are looking for. It's analogous of git reset
if you familiar with git.
Use console:
You need to know the revision number. hg log -l 10
. This command shows the last 10 commits. Find commit you are looking for. You need 4 digit number from changeset line changeset: 5888:ba6205914681
Then hg strip -r 5888 --keep
. This removes the record of the commit but keeps all files modified and then you could recommit them.
(if you want to delete files to just remove --keep hg strip -r 5888
It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.
There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit()
method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.
CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.
Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.
Here input is a string currentUTCTime (in format 08/30/2012 11:11) converts input time in GMT to system set zone time
//UTC time
NSDateFormatter *utcDateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[utcDateFormatter setDateFormat:@"MM/dd/yyyy HH:mm"];
[utcDateFormatter setTimeZone :[NSTimeZone timeZoneForSecondsFromGMT: 0]];
// utc format
NSDate *dateInUTC = [utcDateFormatter dateFromString: currentUTCTime];
// offset second
NSInteger seconds = [[NSTimeZone systemTimeZone] secondsFromGMT];
// format it and send
NSDateFormatter *localDateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[localDateFormatter setDateFormat:@"MM/dd/yyyy HH:mm"];
[localDateFormatter setTimeZone :[NSTimeZone timeZoneForSecondsFromGMT: seconds]];

I found this very annoying bug while converting EmployeeID values with ISNUMERIC:
SELECT DISTINCT [EmployeeID],
ISNUMERIC(ISNULL([EmployeeID], '')) AS [IsNumericResult],
CASE WHEN COALESCE(NULLIF(tmpImport.[EmployeeID], ''), 'Z')
LIKE '%[^0-9]%' THEN 'NonNumeric' ELSE 'Numeric'
END AS [IsDigitsResult]
FROM [MyTable]
This returns:
EmployeeID IsNumericResult MyCustomResult ---------- --------------- -------------- 0 NonNumeric 00000000c 0 NonNumeric 00D026858 1 NonNumeric (3 row(s) affected)
Hope this helps!
Simplest option ...your can change it from AdminConsole. Login to AdminConsole--->Server-->--->Configuration--->ListenPort (Change it)!
Use np.mat(x) * np.mat(y)
, that'll work.
You can use from the pd.to_numeric(s)
Have not tested it yet, but the looks are better than the one Alex mentions.
The description at winginx.com/en/htaccess says:
About the htaccess to nginx converter
The service is to convert an Apache's .htaccess to nginx configuration instructions.
First of all, the service was thought as a mod_rewrite to nginx converter. However, it allows you to convert some other instructions that have reason to be ported from Apache to nginx.
Note server instructions (e.g. php_value, etc.) are ignored.
The converter does not check syntax, including regular expressions and logic errors.
Please, check the result manually before use.
I would use jQuery to get the results that you're looking for. You wouldn't need to use an anchor tag at that point but if you did it would look like:
<a href="page" style="text-decoration:none;display:block;">
<span onclick="hide()">Hide me</span>
</a>
<script type='text/javascript' src='http://code.jquery.com/jquery-1.7.2.min.js' /
<script type='text/javascript'>
$(document).ready(function(){
$('span').click(function(){
$(this).hide();
}
}
Just in case you want a new array you can use sample
:
import random
new_array = random.sample( array, len(array) )
Have you tried rewording your query like this?
@Query("SELECT DISTINCT p.name FROM People p WHERE p.name NOT IN ?1")
List<String> findNonReferencedNames(List<String> names);
Note, I'm assuming your entity class is named People
, and not people
.
In Java, integer literals are of type int by default. For some other types, you may suffix the literal with a case-insensitive letter like L
, D
, F
to specify a long, double, or float, respectively. Note it is common practice to use uppercase letters for better readability.
The Java Language Specification does not provide the same syntactic sugar for byte or short types. Instead, you may declare it as such using explicit casting:
byte foo = (byte)0;
short bar = (short)0;
In your setLongValue(100L)
method call, you don't have to necessarily include the L
suffix because in this case the int literal is automatically widened to a long. This is called widening primitive conversion in the Java Language Specification.
MVC, MVP, MVVM
MVC (old one)
MVP (more modular because of its low-coupling. Presenter is a mediator between the View and Model)
MVVM (You already have two-way binding between VM and UI component, so it is more automated than MVP)
In Objective-C all methods start with either a "-" or "+" character. Example:
@interface MyClass : NSObject
// instance method
- (void) instanceMethod;
+ (void) classMethod;
@end
The "+" and "-" characters specify whether a method is a class method
or an instance method
respectively.
The difference would be clear if we call these methods. Here the methods are declared in MyClass
.
instance method
require an instance of the class:
MyClass* myClass = [[MyClass alloc] init];
[myClass instanceMethod];
Inside MyClass
other methods can call instance methods of MyClass
using self
:
-(void) someMethod
{
[self instanceMethod];
}
But, class methods
must be called on the class itself:
[MyClass classMethod];
Or:
MyClass* myClass = [[MyClass alloc] init];
[myClass class] classMethod];
This won't work:
// Error
[myClass classMethod];
// Error
[self classMethod];
First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):
import static org.mockito.Mockito.*;
There are actually many ways to achieve this, however it's (arguably) cleaner to use the
verify(yourMock, times(0)).someMethod();
method all over your tests, when on other Tests you use it to assert a certain amount of executions like this:
verify(yourMock, times(5)).someMethod();
Alternatives are:
verify(yourMock, never()).someMethod();
Alternatively - when you really want to make sure a certain mocked Object is actually NOT called at all - you can use:
verifyZeroInteractions(yourMock)
The built-in matrix
function has the nice option to enter data byrow
. Combine that with an unlist
on your source list will give you a matrix. We also need to specify the number of rows so it can break up the unlisted data. That is:
> matrix(unlist(a), byrow=TRUE, nrow=length(a) )
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 1 2 3 4 5
[2,] 2 1 2 3 4 5
[3,] 3 1 2 3 4 5
[4,] 4 1 2 3 4 5
[5,] 5 1 2 3 4 5
[6,] 6 1 2 3 4 5
[7,] 7 1 2 3 4 5
[8,] 8 1 2 3 4 5
[9,] 9 1 2 3 4 5
[10,] 10 1 2 3 4 5
You can also do this with positioning, set parent div to relative and child div to absolute.
.wrapper {
position: relative;
}
.childDiv {
position: absolute;
left: 50%;
transform: translateX(-50%);
}
Try AddRange-method:
GlobalStrings.AddRange(localStrings);
If you are getting 500 - Internal server error that means you don't have permission to set these values by .htaccess. You have to contact your web server providers and ask to set AllowOverride Options
for your host or to put these lines in their virtual host configuration file.
You probably want git checkout master
, or git checkout [branchname]
.
To have access to stuff provided by math
module, like pi
. You need to import the module first:
import math
print (math.pi)
You can also pass the function of a struct, like:
package main
// define struct
type Apple struct {}
// return apple's color
func (Apple) GetColor() string {
return "Red"
}
func main () {
// instantiate
myApple := Apple{}
// put the func in a variable
theFunc := myApple.GetColor
// execute the variable as a function
color := theFunc()
print(color)
}
output will be "Red", check on the playground
I solved this (partially) by adding some lines of code to the bootstrap css library. You will have to modify tooltip.js, tooltip.less, popover.js, and popover.less
in tooltip.js, add this case in the switch statement there
case 'bottom-right':
tp = {top: pos.top + pos.height, left: pos.left + pos.width}
break
in tooltip.less, add these two lines in .tooltip{}
&.bottom-right { margin-top: -2px; }
&.bottom-right .tooltip-arrow { #popoverArrow > .bottom(); }
do the same in popover.js and popover.less. Basically, wherever you find code where other positions are mentioned, add your desired position accordingly.
As I mentioned earlier, this solved the problem partially. My problem now is that the little arrow of the popover does not appear.
note: if you want to have the popover in top-left, use top attribute of '.top' and left attribute of '.left'
Some practical examples, somewhat connected to large scale development where Gerrit is used for review and delivery integration:
I merge when I uplift my feature branch to a fresh remote master. This gives minimal uplift work and it's easy to follow the history of the feature development in for example gitk.
git fetch
git checkout origin/my_feature
git merge origin/master
git commit
git push origin HEAD:refs/for/my_feature
I merge when I prepare a delivery commit.
git fetch
git checkout origin/master
git merge --squash origin/my_feature
git commit
git push origin HEAD:refs/for/master
I rebase when my delivery commit fails integration for whatever reason, and I need to update it towards a fresh remote master.
git fetch
git fetch <gerrit link>
git checkout FETCH_HEAD
git rebase origin/master
git push origin HEAD:refs/for/master
The low-level way would be to access the matrix data directly. In an RGB image (which I believe OpenCV typically stores as BGR), and assuming your cv::Mat variable is called frame
, you could get the blue value at location (x
, y
) (from the top left) this way:
frame.data[frame.channels()*(frame.cols*y + x)];
Likewise, to get B, G, and R:
uchar b = frame.data[frame.channels()*(frame.cols*y + x) + 0];
uchar g = frame.data[frame.channels()*(frame.cols*y + x) + 1];
uchar r = frame.data[frame.channels()*(frame.cols*y + x) + 2];
Note that this code assumes the stride is equal to the width of the image.
One way should be to add a <div style="min-width:XXXpx">
within the td, and let the <td style="width:100%">
I was having two .sh scripts to start and stop the digital ocean servers that I wanted to run from the Windows 10. What I did is:
Now to run the script each time I just double-click the script
This code should work:
>>> iter = (i for i in range(50))
>>> sum(1 for _ in iter)
50
Although it does iterate through each item and count them, it is the fastest way to do so.
It also works for when the iterator has no item:
>>> sum(1 for _ in range(0))
0
Of course, it runs forever for an infinite input, so remember that iterators can be infinite:
>>> sum(1 for _ in itertools.count())
[nothing happens, forever]
Also, be aware that the iterator will be exhausted by doing this, and further attempts to use it will see no elements. That's an unavoidable consequence of the Python iterator design. If you want to keep the elements, you'll have to store them in a list or something.
Please read the official Django DOC carefully and you will find the most fit answer.
The best and easist way to solve this is like below.
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = patterns('',
# ... the rest of your URLconf goes here ...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
I like this light weight http request client called `unirest'
gem install unirest
usage:
response = Unirest.post "http://httpbin.org/post",
headers:{ "Accept" => "application/json" },
parameters:{ :age => 23, :foo => "bar" }
response.code # Status code
response.headers # Response headers
response.body # Parsed body
response.raw_body # Unparsed body
There is collection of Func<...>
classes - Func that is probably what you are looking for:
void MyMethod(Func<int> param1 = null)
This defines method that have parameter param1
with default value null
(similar to AS), and a function that returns int
. Unlike AS in C# you need to specify type of the function's arguments.
So if you AS usage was
MyMethod(function(intArg, stringArg) { return true; })
Than in C# it would require param1
to be of type Func<int, siring, bool>
and usage like
MyMethod( (intArg, stringArg) => { return true;} );

It seems problem is not in JDK bug 6602600 ( it was solved at 2010-05-22), but in incorrect call of sleep(10) in circle. Addition note, that the main Thread must give directly CHANCE to other threads to realize thier tasks by invoke SLEEP(0) in EVERY branch of outer circle. It is better, I think, to use Thread.yield() instead of Thread.sleep(0)
The result corrected part of previous problem code is such like this:
.......................
........................
Thread.yield();
if (i % 1000== 0) {
System.out.println(i + "/" + counter.get()+ "/"+service.toString());
}
//
// while (i > counter.get()) {
// Thread.sleep(10);
// }
It works correctly with amount of outer counter up to 150 000 000 tested circles.
There is a pretty library at http://256stuff.com/sources/md5/, with example of use. This is the simplest library for MD5.
Running PHP as a CGI means that you basically tell your web server the location of the PHP executable file, and the server runs that executable
whereas
PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle strenuous loads. PHP-FPM maintains pools (workers that can respond to PHP requests) to accomplish this. PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments
However, there are pros and cons to both and one should choose as per their specific use case.
I found info on this link for fastcgi vs fpm quite helpful in choosing which handler to use in my scenario.
Break
Break forces a loop to exit immediately.
Continue
This does the opposite of break. Instead of terminating the loop, it immediately loops again, skipping the rest of the code.

You can have return
in a void method, you just can't return any value (as in return 5;
), that's why they call it a void method. Some people always explicitly end void methods with a return statement, but it's not mandatory. It can be used to leave a function early, though:
void someFunct(int arg)
{
if (arg == 0)
{
//Leave because this is a bad value
return;
}
//Otherwise, do something
}
Honestly, I hate all the solutions I've seen so far, and I'll tell you why: They just don't seem to ever align it right...so here's what I usually do:
I know what pixel values each div and their respective margins hold...so I do the following.
I'll create a wrapper div that has an absolute position and a left value of 50%...so this div now starts in the middle of the screen, and then I subtract half of all the content of the div's width...and I get BEAUTIFULLY scaling content...and I think this works across all browsers, too. Try it for yourself (this example assumes all content on your site is wrapped in a div tag that uses this wrapper class and all content in it is 200px in width):
.wrapper {
position: absolute;
left: 50%;
margin-left: -100px;
}
EDIT: I forgot to add...you may also want to set width: 0px; on this wrapper div for some browsers to not show the scrollbars, and then you may use absolute positioning for all inner divs.
This also works AMAZING for vertically aligning your content as well using top: 50% and margin-top. Cheers!
No one mentioned that case classes have val
constructor parameters yet this is also the default for regular classes (which I think is an inconsistency in the design of Scala). Dario implied such where he noted they are "immutable".
Note you can override the default by prepending the each constructor argument with var
for case classes. However, making case classes mutable causes their equals
and hashCode
methods to be time variant.[1]
sepp2k already mentioned that case classes automatically generate equals
and hashCode
methods.
Also no one mentioned that case classes automatically create a companion object
with the same name as the class, which contains apply
and unapply
methods. The apply
method enables constructing instances without prepending with new
. The unapply
extractor method enables the pattern matching that others mentioned.
Also the compiler optimizes the speed of match
-case
pattern matching for case classes[2].
XDocument xdoc = XDocument.Load("data.xml");
var lv1s = xdoc.Root.Descendants("level1");
var lvs = lv1s.SelectMany(l=>
new string[]{ l.Attribute("name").Value }
.Union(
l.Descendants("level2")
.Select(l2=>" " + l2.Attribute("name").Value)
)
);
foreach (var lv in lvs)
{
result.AppendLine(lv);
}
Ps. You have to use .Root on any of these versions.
There is a good explanation in the documentation of jQuery.fn.on
.
In short:
Event handlers are bound only to the currently selected elements; they must exist on the page at the time your code makes the call to
.on()
.
Thus in the following example #dataTable tbody tr
must exist before the code is generated.
$("#dataTable tbody tr").on("click", function(event){
console.log($(this).text());
});
If new HTML is being injected into the page, it is preferable to use delegated events to attach an event handler, as described next.
Delegated events have the advantage that they can process events from descendant elements that are added to the document at a later time. For example, if the table exists, but the rows are added dynamically using code, the following will handle it:
$("#dataTable tbody").on("click", "tr", function(event){
console.log($(this).text());
});
In addition to their ability to handle events on descendant elements which are not yet created, another advantage of delegated events is their potential for much lower overhead when many elements must be monitored. On a data table with 1,000 rows in its tbody
, the first code example attaches a handler to 1,000 elements.
A delegated-events approach (the second code example) attaches an event handler to only one element, the tbody
, and the event only needs to bubble up one level (from the clicked tr
to tbody
).
Note: Delegated events do not work for SVG.
String.valueOf('X')
will create you a String "X"
"X".charAt(0)
will give you the character 'X'

You can test with jQuery
if any child div has a certain class. Then by applying that class when you mouse over and out out a certain div, you can test whether your mouse is over it, even when you mouse over a different element on the page Much less code this way. I used this because I had spaces between divs in a pop-up, and I only wanted to close the pop up when I moved off of the pop up, not when I was moving my mouse over the spaces in the pop up. So I called a mouseover function on the content div (which the pop up was over), but it would only trigger the close function when I moused-over the content div, AND was outside the pop up!
$(".pop-up").mouseover(function(e) { $(this).addClass("over"); }); $(".pop-up").mouseout(function(e) { $(this).removeClass("over"); }); $("#mainContent").mouseover(function(e){ if (!$(".expanded").hasClass("over")) { Drupal.dhtmlMenu.toggleMenu($(".expanded")); } });
when I started xampp on my windows 10 there were many options available, unfortunately every one of them failed. I ll list them so that you don't go through all of them again.
1) i installed xampp initially in a different drive and not c because of UAC issues so i uninstalled Xampp and installed it again in c (didn't work) 2) while reinstalling i deactivated the antivirus as setup said that some installing might not end up properly(realized it doesn't matter :) lmao) 3) i tried to change ports several times of xampp from 80 to some different number like 8080 etc. still nothing happened 4) i then tried using firefox as it is believed that internet explorer or internet edge is not a good browser for xampp 5) after that i went to config file i.e config.inc inside phpmyadmin folder and did some crap as were given in the instructions. Failure it was 6) then i closed laptop and went to sleep(XD srry leave this point) 7) then i tried searching for windows web services in the services.msc to disable it. i couldn't find it
On eighth time i got success.This is what i did 8)In control panel, where you have actions , modules PIDs, Ports you will see Services under which you will see gray boxes which are actually checkboxes but are empty initially. i checked it so that xampp services start and apache services start. now you will see them ticked. After that just change the port of xampp and apache to 80.
I hope it helps. cheers ;)

For my problem this code worked, I had to navigate to an anchor tag on page load :
$(window).scrollTop($('a#captchaAnchor').position().top);
For that matter you can use this on any element, not just an anchor tag.
My answer only supports single line text. Check out gfullam's comment below for the multi-line fork, it looks pretty promising.
I rewrote the code from the first answer a few times, and I think this should be the fastest.
It first finds an "Estimated" text length, and then adds or removes a character until the width is correct.
The logic it uses is shown below:
After an "estimated" text length is found, characters are added or removed until the desired width is reached.
I'm sure it needs some tweaking, but here's the code:
(function ($) {
$.fn.ellipsis = function () {
return this.each(function () {
var el = $(this);
if (el.css("overflow") == "hidden") {
var text = el.html().trim();
var t = $(this.cloneNode(true))
.hide()
.css('position', 'absolute')
.css('overflow', 'visible')
.width('auto')
.height(el.height())
;
el.after(t);
function width() { return t.width() > el.width(); };
if (width()) {
var myElipse = "....";
t.html(text);
var suggestedCharLength = (text.length * el.width() / t.width()) - myElipse.length;
t.html(text.substr(0, suggestedCharLength) + myElipse);
var x = 1;
if (width()) {

Simply add static
in the declaration of these two methods and the compile time error will disappear!
By default in C# methods are instance methods, and they receive the implicit "self" argument. By making them static, no such argument is needed (nor available), and the method must then of course refrain from accessing any instance (non-static) objects or methods of the class.
More info on static methods
Provided the class and the method's access modifiers (public vs. private) are ok, a static method can then be called from anywhere without having to previously instantiate a instance of the class. In other words static methods are used with the following syntax:
className.classMethod(arguments)
rather than
someInstanceVariable.classMethod(arguments)
A classical example of static methods are found in the System.Math class, whereby we can call a bunch of these methods like
Math.Sqrt(2)
Math.Cos(Math.PI)
without ever instantiating a "Math" class (in fact I don't even know if such an instance is possible)
Look at the types of those properties:
In [1]: import datetime
In [2]: d = datetime.date.today()
In [3]: type(d.month)
Out[3]: <type 'int'>
In [4]: type(d.day)
Out[4]: <type 'int'>
Both are integers. So there is no automatic way to do what you want. So in the narrow sense, the answer to your question is no.
If you want leading zeroes, you'll have to format them one way or another. For that you have several options:
In [5]: '{:02d}'.format(d.month)
Out[5]: '03'
In [6]: '%02d' % d.month
Out[6]: '03'
In [7]: d.strftime('%m')
Out[7]: '03'
In [8]: f'{d.month:02d}'
Out[8]: '03'
API Sanity Checker — test framework for C/C++ libraries:
An automatic generator of basic unit tests for a shared C/C++ library. It is able to generate reasonable (in most, but unfortunately not all, cases) input data for parameters and compose simple ("sanity" or "shallow"-quality) test cases for every function in the API through the analysis of declarations in header files.
The quality of generated tests allows to check absence of critical errors in simple use cases. The tool is able to build and execute generated tests and detect crashes (segfaults), aborts, all kinds of emitted signals, non-zero program return code and program hanging.
Examples:
Copy the hosts
file and add 127.0.0.1
and name which you want to show or run at the browser link. For example:
127.0.0.1 abc
Then run abc/
as a local host in the browser.
One way I can imagine is to use a linked list to implement such a scenario, if you need all the numbers entered before the user enters something which indicates the loop termination. (posting as the first option, because have never done this for user input, it just seemed to be interesting. Wasteful but artistic)
Another way is to do buffered input. Allocate a buffer, fill it, re-allocate, if the loop continues (not elegant, but the most rational for the given use-case).
I don't consider the described to be elegant though. Probably, I would change the use-case (the most rational).
The Problem is with your code formatting,
inorder to use strtotime()
You should replace '06/Oct/2011:19:00:02'
with 06/10/2011 19:00:02
and date('d/M/Y:H:i:s', $date);
with date('d/M/Y H:i:s', $date);
. Note the spaces in between.
So the final code looks like this
$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);
You can't according to the PHP manual:
Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.
This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.
But you can work around it by also setting $_COOKIE
when you call setcookie()
:
if(!isset($_COOKIE['lg'])) {
setcookie('lg', 'ro');
$_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];
With the Factory pattern, you produce instances of implementations (Apple
, Banana
, Cherry
, etc.) of a particular interface -- say, IFruit
.
With the Abstract Factory pattern, you provide a way for anyone to provide their own factory. This allows your warehouse to be either an IFruitFactory
or an IJuiceFactory
, without requiring your warehouse to know anything about fruits or juices.
You can also use rowcount, but TOP is probably better and cleaner, hence the upvote for Mehrdad
SET ROWCOUNT 10
SELECT * FROM dbo.Orders
WHERE EmployeeID = 5
ORDER BY OrderDate
SET ROWCOUNT 0
You can use html5 tag to download the image directly
<?php
$file = "Bang.png"; //Let say If I put the file name Bang.png
echo "<a href='download.php?nama=".$file."' download>donload</a> ";
?>

You do it exactly as you showed with this line:
get.setHeader("Content-Type", "application/x-zip");
So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.
If you use "format-table" you can use -hidetableheaders
To add to the good answer by @Tomalak:
Here are some unmentioned and important differences:
xsl:apply-templates
is much richer and deeper than xsl:call-templates
and even from xsl:for-each
, simply because we don't know what code will be applied on the nodes of
the selection -- in the general case this code will be different for
different nodes of the node-list.
The code that will be applied
can be written way after the xsl:apply template
s was written and by
people that do not know the original author.
The FXSL library's implementation of higher-order functions (HOF) in XSLT wouldn't be possible if XSLT didn't have the <xsl:apply-templates>
instruction.
Summary: Templates and the <xsl:apply-templates>
instruction is how XSLT implements and deals with polymorphism.

You can use std::find
for this:
#include <algorithm> // for std::find
#include <iterator> // for std::begin, std::end
int main ()
{
int a[] = {3, 6, 8, 33};
int x = 8;
bool exists = std::find(std::begin(a), std::end(a), x) != std::end(a);
}
std::find
returns an iterator to the first occurrence of x
, or an iterator to one-past the end of the range if x
is not found.
Try this:
Private Sub CreateSheet()
Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets.Add(After:= _
ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count))
ws.Name = "Tempo"
End Sub
Or use a With
clause to avoid repeatedly calling out your object
Private Sub CreateSheet()
Dim ws As Worksheet
With ThisWorkbook
Set ws = .Sheets.Add(After:=.Sheets(.Sheets.Count))
ws.Name = "Tempo"
End With
End Sub
Above can be further simplified if you don't need to call out on the same worksheet in the rest of the code.
Sub CreateSheet()
With ThisWorkbook
.Sheets.Add(After:=.Sheets(.Sheets.Count)).Name = "Temp"
End With
End Sub

Here's a simple, pure-Python implementation. It should be used when performance is not critical (included for future Googlers).
import string
allowed = set(string.ascii_lowercase + string.digits + '.')
def check(test_str):
set(test_str) <= allowed
Regarding performance, iteration will probably be the fastest method. Regexes have to iterate through a state machine, and the set equality solution has to build a temporary set. However, the difference is unlikely to matter much. If performance of this function is very important, write it as a C extension module with a switch statement (which will be compiled to a jump table).
Here's a C implementation, which uses if statements due to space constraints. If you absolutely need the tiny bit of extra speed, write out the switch-case. In my tests, it performs very well (2 seconds vs 9 seconds in benchmarks against the regex).
#define PY_SSIZE_T_CLEAN
#include <Python.h>
static PyObject *check(PyObject *self, PyObject *args)
{
const char *s;
Py_ssize_t count, ii;
char c;
if (0 == PyArg_ParseTuple (args, "s#", &s, &count)) {
return NULL;
}
for (ii = 0; ii < count; ii++) {
c = s[ii];
if ((c < '0' && c != '.') || c > 'z') {
Py_RETURN_FALSE;
}
if (c > '9' && c < 'a') {
Py_RETURN_FALSE;
}
}
Py_RETURN_TRUE;
}
PyDoc_STRVAR (DOC, "Fast stringcheck");

{"check", (PyCFunction) (check), METH_VARARGS, NULL},
{NULL, NULL}
};
PyMODINIT_FUNC
initstringcheck (void) {
Py_InitModule3 ("stringcheck", PROCEDURES, DOC);
}
Include it in your setup.py:
from distutils.core import setup, Extension
ext_modules = [
Extension ('stringcheck', ['stringcheck.c']),
],
Use as:
>>> from stringcheck import check
>>> check("abc")
True

False
For the 24-hour time, you need to use HH24
instead of HH
.
For the 12-hour time, the AM/PM indicator is written as A.M.
(if you want periods in the result) or AM
(if you don't). For example:
SELECT invoice_date,
TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
FROM invoices
;
For more information on the format models you can use with TO_CHAR
on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.
Actually you must make sure that the IIS Management Console feature is explicitly checked. On my win 10 pro I had to do it manually, checking the root only was not enough!
The problem is that the number of <th> tags need to match the number of columns in the configuration (the array with the key "columns"). If there are fewer <th> tags than columns specified, you get this slightly cryptical error message.
(the correct answer is already present as a comment but I'm repeating it as an answer so it's easier to find - I didn't see the comments)
The first one will be implemented:
Collection.Where(x => x.Age == 10)
.Where(x => x.Name == "Fido") // applied to the result of the previous
.Where(x => x.Fat == true) // applied to the result of the previous
As opposed to the much simpler (and far fasterpresumably faster):
// all in one fell swoop
Collection.Where(x => x.Age == 10 && x.Name == "Fido" && x.Fat == true)
There is a standard feature echo:
in cmd/bat-files to write blank line, which emulates a new line in your cmd-output:
@echo off
@echo line1
@echo:
@echo line2
Output of cited above cmd-file:
line1
line2
I think this wont be true for all the cases. Because css will download parallel but js cant. Consider for the same case,
Instead of having single css, take 2 or 3 css files and try it out these ways,
1) css..css..js 2) css..js..css 3) js..css..css
I'm sure css..css..js will give better result than all others.
