If you are using the free software R, you can open the matlab files in Rstudio. Very easy!
For those who use NSwag and need a custom header:
app.UseSwaggerUi3(typeof(Startup).GetTypeInfo().Assembly, settings =>
{
settings.GeneratorSettings.IsAspNetCore = true;
settings.GeneratorSettings.OperationProcessors.Add(new OperationSecurityScopeProcessor("custom-auth"));
settings.GeneratorSettings.DocumentProcessors.Add(
new SecurityDefinitionAppender("custom-auth", new SwaggerSecurityScheme
{
Type = SwaggerSecuritySchemeType.ApiKey,
Name = "header-name",
Description = "header description",
In = SwaggerSecurityApiKeyLocation.Header
}));
});
}
Swagger UI will then include an Authorize button.
Rule of three in C++ is a fundamental principle of the design and the development of three requirements that if there is clear definition in one of the following member function, then the programmer should define the other two members functions together. Namely the following three member functions are indispensable: destructor, copy constructor, copy assignment operator.
Copy constructor in C++ is a special constructor. It is used to build a new object, which is the new object equivalent to a copy of an existing object.
Copy assignment operator is a special assignment operator that is usually used to specify an existing object to others of the same type of object.
There are quick examples:
// default constructor
My_Class a;
// copy constructor
My_Class b(a);
// copy constructor
My_Class c = a;
// copy assignment operator
b = a;
Use the Git History Diff plugin for easy side-by-side branch diffing:
https://marketplace.visualstudio.com/items?itemName=huizhou.githd
Visit the link above and scroll down to the animated GIF image titled Diff Branch. You'll see you can easily pick any branch and do side-by-side comparison with the branch you are on! It is like getting a preview of what you will see in the GitHub Pull Request. For other Git stuff I prefer Visual Studio Code's built-in functionality or Git Lens as others have mentioned.
However, the above plugin is outstanding for doing branch diffing (i.e., for those doing a rebase Git flow and need to preview before a force push up to a GitHub PR).
I launched ubuntu Xampp server on AWS amazon. And met the same problem with FTP, even though add user to group ftp SFTP and set permissions, owner group of htdocs folder. Finally find the reason in inbound rules in security group, added All TCP, 0 - 65535 rule(0.0.0.0/0,::/0) , then working right!
Color? color = null;
or you can use
Color? color = new Color?();
example where assigning null wont work
color = x == 5 ? Color.Red : x == 9 ? Color.Black : null ;
so you can use :
color = x == 5 ? Color.Red : x == 9 ? Color.Black : new Color?();
Here is a variant for dynamically adding a class
function setClassStyle(class_name, css) {
var style_sheet = document.createElement('style');
if (style_sheet) {
style_sheet.setAttribute('type', 'text/css');
var cstr = '.' + class_name + ' {' + css + '}';
var rules = document.createTextNode(cstr);
if(style_sheet.styleSheet){// IE
style_sheet.styleSheet.cssText = rules.nodeValue;
} else {
style_sheet.appendChild(rules);
}
var head = document.getElementsByTagName('head')[0];
if (head) {
head.appendChild(style_sheet);
}
}
}
try:
.row {
margin-left: 0;
margin-right: 0;
}
Every column have a padding of 15 px on both sides. Which makes a gutter between of 30 px. In the case of the sm-grid your container class will 970px (((940px + @grid-gutter-width))). Every column get a width of 940/12. The resulting @grid-gutter-width/2 on both sides of the grid will be hide with a negative margin of - 15px;. Undoing this negative left-margin set a gutter of 30 px on both sides of the grid. This gutter is build with 15px padding of the column + 15 px resting grid space.
update
In response of the answer of @ElwoodP, consider the follow code:
<div class="container" style="background-color:darkblue;">
<div class="row" style="background-color:yellow;">
<div class="col-md-9" style="background-color:green;">
<div style="background-color:lightblue;">div 1: .col-md-9</div>
<div class="row" style="background-color:orange;">
<div class="col-md-6" style="background-color:red;">
<div style="background-color:lightblue;">div 2: .col-md-6</div>
</div>
<div class="col-md-6" style="background-color:red;">
<div style="background-color:lightblue;">div 2: .col-md-6</div>
</div>
</div>
</div>
<div class="col-md-3" style="background-color:green;">
<div style="background-color:lightblue;">div 1: .col-md-3</div>
</div>
</div>
</div>
In the case of nesting, manipulation the .row class indeed influences the sub grid. Good or fault depends on your expectations / requirements for the subgrid. Changing the margin of the .row
won't break the sub grid.
.row
classwith:
.row {
margin-left: 0;
margin-right: 0;
}
.container
classwith:
.container {
padding-left:30px;
padding-right:30px;
}
Notice sub grids shouldn't wrapped inside a .container
class.
This thread has some great tips. However....
@GirishB's answer isn't correct - sorry. Jartender's is best.
Also, every post in here seems to assume you're logging in to the Linux guest as root, except for @tomoguisuru. Yuck! Don't use root, use a separate user account and "sudo" when you need root privileges. Then this user (or any other user who needs the shared folder) should have membership in the vboxsf group, and @tomoguisuru's command is perfect, even terser than what I use.
Forget running mount yourself. Set up the shared folder to auto mount and you'll find the shared folder - it's under /media in my OEL (RH and Centos probably the same). If it's not there, just run "mount" with no arguments and look for the mounted directory of type vboxsf.
Sending an email from PHP in Windows is a bit of a minefield with gotchas and head scratching. I'll try to walk you through one instance where I got it to work on Windows 7 and PHP 5.2.3 under (IIS) Internet Information Services webserver.
I'm assuming you don't want to use any pre-built framework like CodeIgniter or Symfony which contains email sending capability. We'll be sending an email from a standalone PHP file. I acquired this code from under the codeigniter hood (under system/libraries) and modified it so you can just drop in this Email.php file and it should just work.
This should work with newer versions of PHP. But you never know.
Step 1, You need a username/password with an SMTP server:
I'm using the smtp server from smtp.ihostexchange.net
which is already created and setup for me. If you don't have this you can't proceed. You should be able to use an email client like thunderbird, evolution, Microsoft Outlook, to specify your smtp server and then be able to send emails through there.
Step 2, Create your Hello World Email file:
I'm assuming you are using IIS. So create a file called index.php under C:\inetpub\wwwroot
and put this code in there:
<?php
include("Email.php");
$c = new CI_Email();
$c->from("[email protected]");
$c->to("[email protected]");
$c->subject("Celestial Temple");
$c->message("Dominion reinforcements on the way.");
$c->send();
echo "done";
?>
You should be able to visit this index.php by navigating to localhost/index.php in a browser, it will spew errors because Email.php is missing. But make sure you can at least run it from the browser.
Step 3, Create a file called Email.php
:
Create a new file called Email.php under C:\inetpub\wwwroot
.
Copy/paste this PHP code into Email.php:
https://github.com/sentientmachine/standalone_php_script_send_email/blob/master/Email.php
Since there are many kinds of smtp servers, you will have to manually fiddle with the settings at the top of Email.php
. I've set it up so it automatically works with smtp.ihostexchange.net
, but your smtp server might be different.
For example:
\n
is required.The linked code is too long to paste as a stackoverflow answer, If you want to edit it, leave a comment in here or through github and I'll change it.
Step 4, make sure your php.ini has ssl extension enabled:
Find your PHP.ini file and uncomment the
;extension=php_openssl.dll
So it looks like:
extension=php_openssl.dll
Step 5, Run the index.php file you just made in a browser:
You should get the following output:
220 smtp.ihostexchange.net Microsoft ESMTP MAIL Service ready at
Wed, 16 Apr 2014 15:43:58 -0400 250 2.6.0
<[email protected]> Queued mail for delivery
lang:email_sent
done
Step 6, check your email, and spam folder:
Visit the email account for [email protected] and you should have received an email. It should arrive within 5 or 10 seconds. If you does not, inspect the errors returned on the page. If that doesn't work, try mashing your face on the keyboard on google while chanting: "working at the grocery store isn't so bad."

You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do
for (var i = myArray.length - 1; i >= 0; i--) { console.log(eval(myArray[i])); };
More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.
var result = {}; for (var i = myArray.length - 1; i >= 0; i--) { result[myArray[i]] = eval(myArray[i]); };
I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via
window['myVarName'] = 'namingCollisionsAreFun';

I used zxing-1.3 jar and I had to make some changes implementing code from other answers, so I will leave my solution for others. I did the following:
1) find zxing-1.3.jar, download it and add in properties (add external jar).
2) in my activity layout add ImageView and name it (in my example it was tnsd_iv_qr).
3) include code in my activity to create qr image (in this example I was creating QR for bitcoin payments):
QRCodeWriter writer = new QRCodeWriter();
ImageView tnsd_iv_qr = (ImageView)findViewById(R.id.tnsd_iv_qr);
try {
ByteMatrix bitMatrix = writer.encode("bitcoin:"+btc_acc_adress+"?amount="+amountBTC, BarcodeFormat.QR_CODE, 512, 512);
int width = 512;
int height = 512;
Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
for (int x = 0; x < width; x++) {
for (int y = 0; y < height; y++) {
if (bitMatrix.get(x, y)==0)
bmp.setPixel(x, y, Color.BLACK);
else
bmp.setPixel(x, y, Color.WHITE);
}
}
tnsd_iv_qr.setImageBitmap(bmp);
} catch (WriterException e) {
//Log.e("QR ERROR", ""+e);
}
If someone is wondering, variable "btc_acc_adress" is a String (with BTC adress), amountBTC is a double, with, of course, transaction amount.
In your src/main/resources
put an application.properties
or application.yml
and put a server.contextPath
in there.
server.contextPath=/your/context/here
When starting your application the application will be available at http://localhost:8080/your/context/here
.
For a comprehensive list of properties to set see Appendix A. of the Spring Boot reference guide.
Instead of putting it in the application.properties you can also pass it as a system property when starting your application
java -jar yourapp.jar -Dserver.contextPath=/your/path/here
You shouldn't rely on the order of elements by using prev
or next
. Just use the for
attribute of the label, as it should correspond to the ID of the element you're currently manipulating:
var label = $("label[for='" + $(this).attr('id') + "']");
However, there are some cases where the label will not have for
set, in which case the label will be the parent of its associated control. To find it in both cases, you can use a variation of the following:
var label = $('label[for="' + $(this).attr('id') + '"]');
if(label.length <= 0) {
var parentElem = $(this).parent(),
parentTagName = parentElem.get(0).tagName.toLowerCase();
if(parentTagName == "label") {
label = parentElem;
}
}
I hope this helps!
I assume that you have some sort of List
component and some sort of Item
component. The way I did it in one project was to let the item know if it was active or not; the item would ask the list to scroll it into view if necessary. Consider the following pseudocode:
class List extends React.Component {
render() {
return <div>{this.props.items.map(this.renderItem)}</div>;
}
renderItem(item) {
return <Item key={item.id} item={item}
active={item.id === this.props.activeId}
scrollIntoView={this.scrollElementIntoViewIfNeeded} />
}
scrollElementIntoViewIfNeeded(domNode) {
var containerDomNode = React.findDOMNode(this);
// Determine if `domNode` fully fits inside `containerDomNode`.
// If not, set the container's scrollTop appropriately.
}
}
class Item extends React.Component {
render() {
return <div>something...</div>;
}
componentDidMount() {
this.ensureVisible();
}
componentDidUpdate() {
this.ensureVisible();
}
ensureVisible() {
if (this.props.active) {
this.props.scrollIntoView(React.findDOMNode(this));
}
}
}
A better solution is probably to make the list responsible for scrolling the item into view (without the item being aware that it's even in a list). To do so, you could add a ref
attribute to a certain item and find it with that:
class List extends React.Component {
render() {
return <div>{this.props.items.map(this.renderItem)}</div>;
}
renderItem(item) {
var active = item.id === this.props.activeId;
var props = {
key: item.id,
item: item,
active: active
};
if (active) {
props.ref = "activeItem";
}
return <Item {...props} />
}
componentDidUpdate(prevProps) {
// only scroll into view if the active item changed last render
if (this.props.activeId !== prevProps.activeId) {
this.ensureActiveItemVisible();
}
}
ensureActiveItemVisible() {
var itemComponent = this.refs.activeItem;
if (itemComponent) {
var domNode = React.findDOMNode(itemComponent);
this.scrollElementIntoViewIfNeeded(domNode);
}
}
scrollElementIntoViewIfNeeded(domNode) {
var containerDomNode = React.findDOMNode(this);
// Determine if `domNode` fully fits inside `containerDomNode`.
// If not, set the container's scrollTop appropriately.
}
}
If you don't want to do the math to determine if the item is visible inside the list node, you could use the DOM method scrollIntoView()
or the Webkit-specific scrollIntoViewIfNeeded
, which has a polyfill available so you can use it in non-Webkit browsers.
Working solution is by using in-build: panelClass attribute and set styles in global style.css (with !important):
https://material.angular.io/components/select/api
/* style.css */
.matRole .mat-option-text {
height: 4em !important;
}
_x000D_
<mat-select panelClass="matRole">...
_x000D_
The following worked for me.
array.slice( where_to_start_deleting, array.length )
Here is an example
var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.slice(2, fruits.length);
//Banana,Orange ->These first two we get as resultant
can simply use style inside element
<p style="text-transform: lowercase;">HI I AM NEW HERE</p>
You need to append your variables to the echoed string. For example:

Try creating an inline table-valued function. Example:
CREATE FUNCTION dbo.fxnExample (@Parameter1 INTEGER)
RETURNS TABLE
AS
RETURN
(
SELECT Field1, Field2
FROM SomeTable
WHERE Field3 = @Parameter1
)
-- Then call like this, just as if it's a table/view just with a parameter
SELECT * FROM dbo.fxnExample(1)
If you view the execution plan for the SELECT you will not see a mention of the function at all and will actually just show you the underlying tables being queried. This is good as it means statistics on the underlying tables will be used when generating an execution plan for the query.
The thing to avoid would be a multi-statement table valued function as underlying table statistics will not be used and can result in poor performance due to a poor execution plan.
Example of what to avoid:
CREATE FUNCTION dbo.fxnExample (@Parameter1 INTEGER)
RETURNS @Results TABLE(Field1 VARCHAR(10), Field2 VARCHAR(10))
AS
BEGIN
INSERT @Results
SELECT Field1, Field2
FROM SomeTable
WHERE Field3 = @Parameter1
RETURN
END
Subtly different, but with potentially big differences in performance when the function is used in a query.
URL url = new URL("http://example.com");

This is by no means a robust example; you'll need to handle IOException
s and whatnot. But it should get you started.
If you need something with more capability, check out HttpClient.

}
try this

Use a BackgroundWorker. It will allow you to get callbacks on completion and allow you to track progress. You can set the Result value on the event arguments to the resulting value.
public void UseBackgroundWorker()

worker.RunWorkerCompleted += WorkDone;
worker.RunWorkerAsync("input");
}
public void DoWork(object sender, DoWorkEventArgs e)
{
e.Result = e.Argument.Equals("input");
Thread.Sleep(1000);
}
public void WorkDone(object sender, RunWorkerCompletedEventArgs e)
{
var result = (bool) e.Result;
}
All you have to do is use the runas
command to run your program as Administrator (with a caveat).
runas /user:Administrator "cmdName parameters"
In my case, this was
runas /user:Administator "cmd.exe /C %CD%\installer.cmd %CD%"
Note that you must use Quotation marks, else the runas command will gobble up the switch option to cmd.
Also note that the administrative shell (cmd.exe) starts up in the C:\Windows\System32 folder. This isn't what I wanted, but it was easy enough to pass in the current path to my installer, and to reference it using an absolute path.
Using runas this way requires the administrative account to be enabled, which is not the default on Windows 7 or Vista. However, here is a great tutorial on how to enable it, in three different ways:
I myself enabled it by opening Administrative Tools, Local Security Policy, then navigating to Local Policies\Security Options and changing the value of the Accounts: Administrative Account Status policy to Enabled, which is none of the three ways shown in the link.
An even easier way:
C:> net user Administrator /active:yes
I see a couple of issues.
First:
ser.read() is only going to return 1 byte at a time.
If you specify a count
ser.read(5)
it will read 5 bytes (less if timeout occurrs before 5 bytes arrive.)
If you know that your input is always properly terminated with EOL characters, better way is to use
ser.readline()
That will continue to read characters until an EOL is received.
Second:
Even if you get ser.read() or ser.readline() to return multiple bytes, since you are iterating over the return value, you will still be handling it one byte at a time.
Get rid of the
for line in ser.read():
and just say:
line = ser.readline()
Java 8's stream()
interface provides a great way to update a list in place.
To safely update items in the list, use map()
:
List<String> letters = new ArrayList<>();
// add stuff to list
letters = letters.stream().map(x -> "D").collect(Collectors.toList());
To safely remove items in place, use filter()
:
letters.stream().filter(x -> !x.equals("A")).collect(Collectors.toList());
A short answer is to add the following options when the JVM is started.
JAVA_OPTS=" $JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8080"
You can also initiate a port forward TO your HOST, OR ANY OTHER SERVER, from your Guest. This is especially useful if your Guest is 'locked' or can't otherwise complete the ModifyVM option (e.g. no permission to VBoxManage).
Three minor requirements are 1) you are/can log into the VirtualBox Guest (via 'console' GUI, another Guest, etc), 2) you have an account on the VirtualBox HOST (or other Server), and 3) SSH and TCP forwarding is not blocked.
Presuming you can meet the 3 requirements, these are the steps:
netstat -rn
and find the Gateway address to the default route destination 0.0.0.0. Let's say it's "10.0.2.2". This 'Gateway' address is (one of) the VirtualBox Host virtual IP(s).ssh -R 2222:localhost:22 10.0.2.2
where "10.0.2.2" is the VirtualBox server's IP address -OR- any other server IP you wish to port forward to.ssh 10.0.2.2 -p2222
where 10.0.2.2 is the default gateway/VBHost virtual IP found in step 1. If it is NOT the VirtualBox host you are port forwarding to, then the command is ssh localhost -p2222
The 'Enter some junk value' answer didn't do the trick for me, my site was continuing to load despite the entered junk.
Instead I added the following line to the top of the .htaccess file:
deny from all
This will quickly let you know if .htaccess is being picked up or not. If the .htaccess is being used, the files in that folder won't load at all.
A couple of things:
You need to set the video bitrate. I have never used minrate and maxrate so I don't know how exactly they work, but by setting the bitrate using the -b
switch, I am able to get high quality video. You need to come up with a bitrate that offers a good tradeoff between compression and video quality. You may have to experiment with this because it all depends on the frame size, frame rate and the amount of motion in the content of your video. Keep in mind that DVD tends to be around 4-5 Mbit/s on average for 720x480, so I usually start from there and decide whether I need more or less and then just experiment. For example, you could add -b 5000k
to the command line to get more or less DVD video bitrate.
You need to specify a video codec. If you don't, ffmpeg will default to MPEG-1 which is quite old and does not provide near the amount of compression as MPEG-4 or H.264. If your ffmpeg version is built with libx264 support, you can specify -vcodec libx264
as part of the command line. Otherwise -vcodec mpeg4
will also do a better job than MPEG-1, but not as well as x264.
There are a lot of other advanced options that will help you squeeze out the best quality at the lowest bitrates. Take a look here for some examples.
How about a list?
mystring.split(",")
It might help if you could explain what kind of info we are looking at. Maybe some background info also?
EDIT:
I had a thought you might want the info in groups of two?
then try:
re.split(r"\d*,\d*", mystring)
and also if you want them into tuples
[(pair[0], pair[1]) for match in re.split(r"\d*,\d*", mystring) for pair in match.split(",")]
in a more readable form:
mylist = []
for match in re.split(r"\d*,\d*", mystring):
for pair in match.split(",")
mylist.append((pair[0], pair[1]))
Why not merge the rows that contain the same values? -
13 21 29 37 45
1000] -75.2 -- 79.21 -- 80.02
5000] ---------------------87.9---88.54----88.56
10000] -------------------90.11--90.97----90.87
Excel can use that pretty well..
You need to put the last()
indexing on the nodelist result, rather than as part of the selection criteria. Try:
(//element[@name='D'])[last()]
Here is a bare bones version:
Let's say that you have a date in Cell A1 in the format you described. For example: 19760210
.
Then this formula will give you the date you want:
=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2)).
On my system (Excel 2010) it works with strings or floats.
Use the System.Runtime.InteropServices.Marshal
class:
String SecureStringToString(SecureString value) {
IntPtr valuePtr = IntPtr.Zero;
try {
valuePtr = Marshal.SecureStringToGlobalAllocUnicode(value);
return Marshal.PtrToStringUni(valuePtr);
} finally {
Marshal.ZeroFreeGlobalAllocUnicode(valuePtr);
}
}
If you want to avoid creating a managed string object, you can access the raw data using Marshal.ReadInt16(IntPtr, Int32)
:
void HandleSecureString(SecureString value) {
IntPtr valuePtr = IntPtr.Zero;
try {
valuePtr = Marshal.SecureStringToGlobalAllocUnicode(value);
for (int i=0; i < value.Length; i++) {
short unicodeChar = Marshal.ReadInt16(valuePtr, i*2);
// handle unicodeChar
}
} finally {
Marshal.ZeroFreeGlobalAllocUnicode(valuePtr);
}
}
I had an issue like this, and found the solution was to do with Underscore.js. My initial logging made no sense:
console.log(JSON.stringify(obj, null, 2));
> {
> "code": "foo"
> }
console.log(obj.code);
> undefined
I found the solution by also looking at the keys of the object:
console.log(JSON.stringify(Object.keys(obj)));
> ["_wrapped","_chain"]
This lead me to realise that obj
was actually an Underscore.js wrapper around an object, and the initial debugging was lying to me.
First I added a to_dict method to my model ;
def to_dict(self):
return {"name": self.woo, "title": self.foo}
Then I have this;
class DjangoJSONEncoder(JSONEncoder):
def default(self, obj):
if isinstance(obj, models.Model):
return obj.to_dict()
return JSONEncoder.default(self, obj)
dumps = curry(dumps, cls=DjangoJSONEncoder)
and at last use this class to serialize my queryset.
def render_to_response(self, context, **response_kwargs):
return HttpResponse(dumps(self.get_queryset()))
This works quite well
when you pass an object within curly braces as an argument to a function with one parameter , you're assigning this object to a variable which is the parameter in this case
Use of javafx.util.Pair is sufficient for most simple Key-Value pairings of any two types that can be instantiated.
Pair<Integer, String> myPair = new Pair<>(7, "Seven");
Integer key = myPair.getKey();
String value = myPair.getValue();

Try wrapping your FileWriter
in a BufferedWriter
:
BufferedWriter bw = new BufferedWriter(writer);
bw.newLine();
Javadocs for BufferedWriter here.
You need to define static variables in a translation unit, unless they are of integral types.
In your header:
private:
static const char *SOMETHING;
static const int MyInt = 8; // would be ok
In the .cpp file:
const char *YourClass::SOMETHING = "something";
C++ standard, 9.4.2/4:
If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression. In that case, the member can appear in integral constant expressions within its scope. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.
You can do this entirely with bash 4.3
and above:
_timeout() { ( set +b; sleep "$1" & "${@:2}" & wait -n; r=$?; kill -9 `jobs -p`; exit $r; ) }
_timeout 5 longrunning_command args
{ _timeout 5 producer || echo KABOOM $?; } | consumer
producer | { _timeout 5 consumer1; consumer2; }
Example: { while date; do sleep .3; done; } | _timeout 5 cat | less
Needs Bash 4.3 for wait -n
If you do not need the return code, this can be made even simpler:
_timeout() { ( set +b; sleep "$1" & "${@:2}" & wait -n; kill -9 `jobs -p`; ) }
Notes:
Strictly speaking you do not need the ;
in ; )
, however it makes thing more consistent to the ; }
-case. And the set +b
probably can be left away, too, but better safe than sorry.
Except for --forground
(probably) you can implement all variants timeout
supports. --preserve-status
is a bit difficult, though. This is left as an exercise for the reader ;)
This recipe can be used "naturally" in the shell (as natural as for flock fd
):
(
set +b
sleep 20 &
{
YOUR SHELL CODE HERE
} &
wait -n
kill `jobs -p`
)
However, as explained above, you cannot re-export environment variables into the enclosing shell this way naturally.
Edit:
Real world example: Time out __git_ps1
in case it takes too long (for things like slow SSHFS-Links):
eval "__orig$(declare -f __git_ps1)" && __git_ps1() { ( git() { _timeout 0.3 /usr/bin/git "$@"; }; _timeout 0.3 __orig__git_ps1 "$@"; ) }
Edit2: Bugfix. I noticed that exit 137
is not needed and makes _timeout
unreliable at the same time.
Edit3: git
is a die-hard, so it needs a double-trick to work satisfyingly.
Edit4: Forgot a _
in the first _timeout
for the real world GIT example.
You may want to consider why you want to use a 1-based array at all. Zero-based arrays (when using non-associative arrays) are pretty standard, and if you're wanting to output to a UI, most would handle the solution by just increasing the integer upon output to the UI.
Think about consistency—both in your application and in the code you work with—when thinking about 1-based indexers for arrays.
Go to Project
and hit Clean
. This should, among others, regenerate your R.java file.
Also get rid of any import android.R.*
statements and then do the clean up I mentioned.
Apparently Jonas problem was related to incorrect target build settings. His target build was set to Android 2.1 (SDK v7) where his layout XML used Android 2.2 (SDK v8) elements (layout parameter match_parent
), due to this there was no way for Eclipse to correctly generate the R.java file which caused all the problems.
AJAX is a technique to do an XMLHttpRequest (out of band Http request) from a web page to the server and send/retrieve data to be used on the web page. AJAX stands for Asynchronous Javascript And XML. It uses javascript to construct an XMLHttpRequest, typically using different techniques on various browsers.
jQuery (website) is a javascript framework that makes working with the DOM easier by building lots of high level functionality that can be used to search and interact with the DOM. Part of the functionality of jQuery implements a high-level interface to do AJAX requests. jQuery implements this interface abstractly, shielding the developer from the complexity of multi-browser support in making the request.
var link = $("#me").closest(":has(h3 span b)").find('h3 span b');
Example: http://jsfiddle.net/e27r8/
This uses the closest()
[docs] method to get the first ancestor that has a nested h3 span b
, then does a .find()
.
Of course you could have multiple matches.
Otherwise, you're looking at doing a more direct traversal.
var link = $("#me").closest("h3 + div").prev().find('span b');
edit: This one works with your updated HTML.
Example: http://jsfiddle.net/e27r8/2/
EDIT: Updated to deal with updated question.
var link = $("#me").closest("h3 + *").prev().find('span b');
This makes the targeted element for .closest()
generic, so that even if there is no parent, it will still work.
Example: http://jsfiddle.net/e27r8/4/
I had the same issue and worked it out by nesting a div inside bootstrap col and adding padding to it. Something like:

</div>
<div class="col-md-4">

You should add:
android {
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
exclude '...'
}
}
to your build.gradle
file.
According to comment 14 in this bug: https://issuetracker.google.com/issues/36982149#comment14 this is a bug in v0.7.0 of the Android Gradle plugin, and is due to be fixed soon in 0.7.1.
Here are the notes from that bug about the addition for 0.7.1:
0.7.1 is out with the fix for this.
The DSL to exclude files is:
android {
packagingOptions {
exclude 'META-INF/LICENSE.txt'
}
}
You can add as many exclude statement as you want. The value is the archive path. No wildcard or glob support yet.
Filenames "LICENSE.txt" and "NOTICE.txt" are case sensitive. Please try out with "license.txt" and "notice.txt" as well.
$_
is the active object in the current pipeline. You've started a new pipeline with $FOLDLIST | ...
so $_
represents the objects in that array that are passed down the pipeline. You should stash the FileInfo object from the first pipeline in a variable and then reference that variable later e.g.:
write-host $NEWN.Length
$file = $_
...
Move-Item $file.Name $DPATH
The return value of an event handler determines whether or not the default browser behaviour should take place as well. In the case of clicking on links, this would be following the link, but the difference is most noticeable in form submit handlers, where you can cancel a form submission if the user has made a mistake entering the information.
I don't believe there is a W3C specification for this. All the ancient JavaScript interfaces like this have been given the nickname "DOM 0", and are mostly unspecified. You may have some luck reading old Netscape 2 documentation.
The modern way of achieving this effect is to call event.preventDefault()
, and this is specified in the DOM 2 Events specification.
with a form, just set method
to "post"
<form action="blah.php" method="post">
<input type="text" name="data" value="mydata" />
<input type="submit" />
</form>
The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.
@SuppressWarnings annotation is one of the three built-in annotations available in JDK and added alongside @Override and @Deprecated in Java 1.5.
@SuppressWarnings instruct the compiler to ignore or suppress, specified compiler warning in annotated element and all program elements inside that element. For example, if a class is annotated to suppress a particular warning, then a warning generated in a method inside that class will also be separated.
You might have seen @SuppressWarnings("unchecked") and @SuppressWarnings("serial"), two of most popular examples of @SuppressWarnings annotation. Former is used to suppress warning generated due to unchecked casting while the later warning is used to remind about adding SerialVersionUID in a Serializable class.
Object Model is concerned with the following three concepts Data Abstraction Encapsulation Inheritance The relational model used the basic concept of a relation or table. Object-relational mapping (OR mapping) products integrate object programming language capabilities with relational databases.
Use ` backticks for MYSQL reserved words...
table name "table" is reserved word for MYSQL...
so your query should be as follows...
$sql="INSERT INTO `table` (`username`, `password`)
VALUES
('$_POST[username]','$_POST[password]')";
What you're looking for is modular exponentiation, specifically modular binary exponentiation. This wikipedia link has pseudocode.
Please try
InputStream in = this.getClass().getResourceAsStream("/SomeTextFile.txt");
Your tries didn't work because only the class loader for your classes is able to load from the classpath. You used the class loader for the java system itself.
You could try jQuery UI's .position method.
$("#mydiv").position({
of: $('#mydiv').parent(),
my: 'left+200 top+200',
at: 'left top'
});
My solution to this issue was to create the function shown below. My requirements included that the number had to be a standard integer, not a BIGINT, and I needed to allow negative numbers and positive numbers. I have not found a circumstance where this fails.

(
-- Add the parameters for the function here
@Value nvarchar(max)
)
RETURNS int
AS
BEGIN
-- Declare the return variable here
DECLARE @Result int = 0
-- Add the T-SQL statements to compute the return value here
DECLARE @MinValue nvarchar(11) = '-2147483648'
DECLARE @MaxValue nvarchar(10) = '2147483647'
SET @Value = ISNULL(@Value,'')
IF LEN(@Value)=0 OR
ISNUMERIC(@Value)<>1 OR
(LEFT(@Value,1)='-' AND LEN(@Value)>11) OR
(LEFT(@Value,1)='-' AND LEN(@Value)=11 AND @Value>@MinValue) OR
(LEFT(@Value,1)<>'-' AND LEN(@Value)>10) OR
(LEFT(@Value,1)<>'-' AND LEN(@Value)=10 AND @Value>@MaxValue)
GOTO FINISHED
DECLARE @cnt int = 0
WHILE @cnt<LEN(@Value)
BEGIN
SET @cnt=@cnt+1
IF SUBSTRING(@Value,@cnt,1) NOT IN ('-','0','1','2','3','4','5','6','7','8','9') GOTO FINISHED
END
SET @Result=1
FINISHED:
-- Return the result of the function
RETURN @Result

The document.write method is very limited. You can only use it before the page has finished loading. You can't use it to update the contents of a loaded page.
What you probably want is innerHTML.
This is my solution:
Request.Url.AbsoluteUri.Replace(Request.Url.Query, String.Empty);

function resizeIframe(obj) {
obj.style.height = 0;
obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
}

As already noted the approach for resetting the notification state for an app on a device is changed for iOS5 an newer.
This works for me on iOS6:
However this will only make the initial prompt appear again - it will not remove any other push state related stuff.
$("#btnSubmit").click(function(){
alert("button");
});
@Adrian's answer is perfectly suitable, I just wanted to share another way of achieving the same result:
select nvl(a.id, b.id)

order by b.id;
Edit (as suggested in comments and other people), Visual Studio Code has evolved and provides this functionality in-built as the command "Organize imports", with the following default keyboard shortcuts:
option+Shift+O for Mac
Alt + Shift + O for Windows

I hope this visual studio code extension will suffice your need: https://marketplace.visualstudio.com/items?itemName=rbbit.typescript-hero
It provides following features:
For Mac: control+option+o
For Win: Ctrl+Alt+o

You could can use git rebase
to rewrite the commit history. This can be potentially destructive to your changes, so use with care.
First commit your "amend" change as a normal commit. Then do an interactive rebase starting on the parent of your oldest commit
git rebase -i 47175e84c2cb7e47520f7dde824718eae3624550^
This will fire up your editor with all commits. Reorder them so your "amend" commit comes below the one you want to amend. Then replace the first word on the line with the "amend" commit with s
which will combine (s quash) it with the commit before. Save and exit your editor and follow the instructions.
The following simple steps help me:
First, initialize the repository to work with Git
, so that any file changes are tracked:
git init
Then, check that the remote repository that you want to associate with the alias origin
exists, if not create it in git
first.
$ git ls-remote https://github.com/repo-owner/repo-name.git/
If it exists, associate it with the remote "origin":
git remote add origin https://github.com:/repo-owner/repo-name.git
and check to which URL, the remote "origin" belongs to by using git remote -v
:
$ git remote -v
origin https://github.com:/repo-owner/repo-name.git (fetch)
origin https://github.com:/repo-owner/repo-name.git (push)
Next, verify if your origin is properly aliased as follows:
$ cat ./.git/config
:
[remote "origin"]
url = https://github.com:/repo-owner/repo-name.git
fetch = +refs/heads/*:refs/remotes/origin/*
:
You need to see this section [remote "origin"]
. You can consider to use GitHub Desktop available for both Windows and MacOS, which help me to automatically populate the missing section/s in ~./git/config
file OR you can manually add it, not great, but hey it works!
[Optional]
You might also want to change the origin
alias to make it more intuitive, especially if you are working with multiple origin
:
git remote rename origin mynewalias
or even remove it:
git remote rm origin
Finally, on your first push, if you want master
in that repository to be your default upstream. you may want to add the -u
parameter
git add .
git commit -m 'First commit'
git push -u origin master
I know it's an old question, but here is another solution:
This duplicates a row in the main table, assuming the primary key is auto-increment, and creates copies of linked-tables data with the new main table id.
Other options for getting column names:
-SHOW COLUMNS FROM tablename
; (Column name: Field)

The answer comes from the javadoc of ZoneId
(emphasis mine) ...
A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:
- Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
- Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply
Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.
... and from the javadoc of ZoneId#of
(emphasis mine):
This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.
The argument id is specified as "UTC"
, therefore it will return a ZoneId
with an offset, which also presented in the string form:
System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));
Outputs:
2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]
As you use the equals
method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false
.
When the normalized()
method is used as proposed in the documentation, the comparison using equals
will return true
, as normalized()
will return the corresponding ZoneOffset
:
Normalizes the time-zone ID, returning a ZoneOffset where possible.
now.withZoneSameInstant(ZoneOffset.UTC)
.equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true
As the documentation states, if you use "Z"
or "+0"
as input id, of
will return the ZoneOffset
directly and there is no need to call normalized()
:
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true
To check if they store the same date time, you can use the isEqual
method instead:
now.withZoneSameInstant(ZoneOffset.UTC)
.isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true
Sample
System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
.equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
.isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));
Output:
equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true
The error is here:
hasLetter("a",words[]);
You are passing the first item of words
, instead of the array.
Instead, pass the array to the function:
hasLetter("a",words);
Problem solved!
Here's a breakdown of what the problem was:
I'm guessing in your browser (chrome throws a different error), words[] == words[0]
, so when you call hasLetter("a",words[]);
, you are actually calling hasLetter("a",words[0]);
. So, in essence, you are passing the first item of words to your function, not the array as a whole.
Of course, because words
is just an empty array, words[0]
is undefined
. Therefore, your function call is actually:
hasLetter("a", undefined);
which means that, when you try to access d[ascii]
, you are actually trying to access undefined[0]
, hence the error.
FormulaR1C1 has the same behavior as Formula, only using R1C1 style annotation, instead of A1 annotation. In A1 annotation you would use:
Worksheets("Sheet1").Range("A5").Formula = "=A4+A10"
In R1C1 you would use:
Worksheets("Sheet1").Range("A5").FormulaR1C1 = "=R4C1+R10C1"
It doesn't act upon row 1 column 1, it acts upon the targeted cell or range. Column 1 is the same as column A, so R4C1 is the same as A4, R5C2 is B5, and so forth.
The command does not change names, the targeted cell changes. For your R2C3 (also known as C2) example :
Worksheets("Sheet1").Range("C2").FormulaR1C1 = "=your formula here"
If that version you need to obtain is either a branch or a tag then:
git clone -b branch_or_tag_name repo_address_or_path
I was having the same issue
Role.java
@ManyToMany(mappedBy = "roles", fetch = FetchType.LAZY,cascade = CascadeType.ALL)
Set<BusinessUnitMaster> businessUnits =new HashSet<>();
BusinessUnitMaster.java
@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(
name = "BusinessUnitRoles",
joinColumns = {@JoinColumn(name = "unit_id", referencedColumnName = "record_id")},
inverseJoinColumns = {@JoinColumn(name = "role_id", referencedColumnName = "record_id")}
)
private Set<Role> roles=new HashSet<>();
the problem is that when you create BusinessUnitMaster and Role you have to save the object for both sides for RoleService.java
roleRepository.save(role);
for BusinessUnitMasterService.java
businessUnitMasterRepository.save(businessUnitMaster);
Great question, great answers. Here's a quick way to echo the results if anyone is reading this page and missing that part:
$counter = mysql_query("SELECT COUNT(*) AS id FROM table");
$num = mysql_fetch_array($counter);
$count = $num["id"];
echo("$count");
Use the %pylab inline
magic command.
git diff branch_1..branch_2
That will produce the diff between the tips of the two branches. If you'd prefer to find the diff from their common ancestor to test, you can use three dots instead of two:
git diff branch_1...branch_2
Swift 3
If you need the object use:
array.first{$0.name == "Foo"}
(If you have more than one object named "Foo" then first
will return the first object from an unspecified ordering)
unit test: testing of individual module or independent component in an application is known to be unit testing , the unit testing will be done by developer.
integration test: combining all the modules and testing the application to verify the communication and the data flow between the modules are working properly or not , this testing also performed by developers.
funcional test checking the individual functionality of an application is mean to be functional testing
acceptance testing this testing is done by end user or customer whether the build application is according to the customer requirement , and customer specification this is known to be acceptance testing
I'm surprised that no one has offered something like the following (harvested from the RAPI gem):
class Enum
private
def self.enum_attr(name, num)
name = name.to_s
define_method(name + '?') do
@attrs & num != 0
end
define_method(name + '=') do |set|
if set
@attrs |= num
else
@attrs &= ~num
end
end
end
public
def initialize(attrs = 0)
@attrs = attrs
end
def to_i
@attrs
end
end
Which can be used like so:
class FileAttributes < Enum
enum_attr :readonly, 0x0001
enum_attr :hidden, 0x0002
enum_attr :system, 0x0004
enum_attr :directory, 0x0010
enum_attr :archive, 0x0020
enum_attr :in_rom, 0x0040
enum_attr :normal, 0x0080
enum_attr :temporary, 0x0100
enum_attr :sparse, 0x0200
enum_attr :reparse_point, 0x0400
enum_attr :compressed, 0x0800
enum_attr :rom_module, 0x2000
end
Example:
>> example = FileAttributes.new(3)
=> #<FileAttributes:0x629d90 @attrs=3>
>> example.readonly?
=> true
>> example.hidden?
=> true
>> example.system?
=> false
>> example.system = true
=> true
>> example.system?
=> true
>> example.to_i
=> 7
This plays well in database scenarios, or when dealing with C style constants/enums (as is the case when using FFI, which RAPI makes extensive use of).
Also, you don't have to worry about typos causing silent failures, as you would with using a hash-type solution.
to remove symbol use tag [ ]
step:1
[]
step 2:place what symbol u want to remove eg:@ like [@]
[@]
step 3:
var name = name.replace(/[@]/g, "");
thats it
var name="ggggggg@fffff"
var result = name.replace(/[@]/g, "");
console .log(result)
_x000D_
Extra Tips
To remove space (give one space into square bracket like []=>[ ])
[@ ]
It Remove Everything (using except)
[^place u dont want to remove]
eg:i remove everyting except alphabet (small and caps)
[^a-zA-Z ]
var name="ggggg33333@#$%^&**I(((**gg@fffff"
var result = name.replace(/[^a-zA-Z]/g, "");
console .log(result)
_x000D_
Stack corruptions ususally caused by buffer overflows. You can defend against them by programming defensively.
Whenever you access an array, put an assert before it to ensure the access is not out of bounds. For example:
assert(i + 1 < N);
assert(i < N);
a[i + 1] = a[i];
This makes you think about array bounds and also makes you think about adding tests to trigger them if possible. If some of these asserts can fail during normal use turn them into a regular if
.
For info, in your .bowerrc
file you can add a no-proxy attribute. I don't know since when it is supported but it works on bower 1.7.4
.bowerrc :
{
"directory": "bower_components",
"proxy": "http://yourProxy:yourPort",
"https-proxy":"http://yourProxy:yourPort",
"no-proxy":"myserver.mydomain.com"
}
.bowerrc
should be located in the root folder of your Javascript project, the folder in which you launch the bower command. You can also have it in your home folder (~/.bowerrc
).
By the time the query gets to SQL you have to have already expanded the list. The easy way of doing this, if you're using IDs from some internal, trusted data source, where you can be 100% certain they're integers (e.g., if you selected them from your database earlier) is this:
$sql = 'SELECT * WHERE id IN (' . implode(',', $ids) . ')';
If your data are coming from the user, though, you'll need to ensure you're getting only integer values, perhaps most easily like so:
$sql = 'SELECT * WHERE id IN (' . implode(',', array_map('intval', $ids)) . ')';
Until today (9 jan 2014) the Bootstrap 3 still not support sub menu dropdown.
I searched Google about responsive navigation menu and found this is the best i though.
It is Smart menus http://www.smartmenus.org/
I hope this is the way out for anyone who want navigation menu with multilevel sub menu.
update 2015-02-17 Smart menus are now fully support Bootstrap element style for submenu. For more information please look at Smart menus website.
Here is another possible workaround:
if exists (select * from master..sysservers where srvname = 'loopback')
exec sp_dropserver 'loopback'
go
exec sp_addlinkedserver @server = N'loopback', @srvproduct = N'', @provider = N'SQLOLEDB', @datasrc = @@servername
go
create function testit()
returns int
as
begin
declare @res int;
select @res=count(*) from openquery(loopback, 'exec sp_who');
return @res
end
go
select dbo.testit()
It's not so scary as xp_cmdshell
but also has too many implications for practical use.
To also highlight the menu item when one of the child pages is active, also check for the other class (current-page-ancestor
) like below:
add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);
function special_nav_class ($classes, $item) {
if (in_array('current-page-ancestor', $classes) || in_array('current-menu-item', $classes) ){
$classes[] = 'active ';
}
return $classes;
}
A three-liner to combine or merge two dictionaries:
dest = {}
dest.update(orig)
dest.update(extra)
This creates a new dictionary dest
without modifying orig
and extra
.
Note: If a key has different values in orig
and extra
, then extra
overrides orig
.
Based on Rohith Nandakumar's solution, I did something of my own to copy files from a subfolder of assets (i.e. "assets/MyFolder"). Also, I'm checking if the file already exists in sdcard before trying to copy again.
private void copyAssets() {
AssetManager assetManager = getAssets();
String[] files = null;
try {
files = assetManager.list("MyFolder");
} catch (IOException e) {
Log.e("tag", "Failed to get asset file list.", e);
}
if (files != null) for (String filename : files) {
InputStream in = null;
OutputStream out = null;
try {
in = assetManager.open("MyFolder/"+filename);
File outFile = new File(getExternalFilesDir(null), filename);
if (!(outFile.exists())) {// File does not exist...
out = new FileOutputStream(outFile);
copyFile(in, out);
}
} catch(IOException e) {
Log.e("tag", "Failed to copy asset file: " + filename, e);
}
finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
// NOOP
}
}
if (out != null) {
try {
out.close();
} catch (IOException e) {
// NOOP
}
}
}
}
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while((read = in.read(buffer)) != -1){
out.write(buffer, 0, read);
}
}
Activity is a context so if you can simply check the context is an Activity and cast it if necessary.
@Override
public void onAttach(Context context) {
super.onAttach(context);
Activity a;
if (context instanceof Activity){
a=(Activity) context;
}
}
Update: Some are claiming that the new Context
override is never called. I have done some tests and cannot find a scenario where this is true and according to the source code, it should never be true. In all cases I tested, both pre and post SDK23, both the Activity
and the Context
versions of onAttach
were called. If you can find a scenario where this is not the case, I would suggest you create a sample project illustrating the issue and report it to the Android team.
Update 2: I only ever use the Android Support Library fragments as bugs get fixed faster there. It seems the above issue where the overrides do not get called correctly only comes to light if you use the framework fragments.
Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS
// Example using HTTP POST operation
var page = require('webpage').create(),
server = 'http://posttestserver.com/post.php?dump',
data = 'universe=expanding&answer=42';
page.open(server, 'post', data, function (status) {
if (status !== 'success') {
console.log('Unable to post!');
} else {
console.log(page.content);
}
phantom.exit();
});
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;} );
For python 2.7 I had the same issue Just use "from __future__ import print_function" without quotes to resolve this issue.This Ensures Python 2.6 and later Python 2.x can use Python 3.x print function.
I broke my head to understand why your answers for WPA/WPA2 don't work...after hours of tries I found what you are missing:
conf.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
is REQUIRED for WPA networks!!!!
Now, it works :)
This is another way of tackling the problem if you have long strings (like file path names) and you only want to break the strings on certain characters (like slashes). You can insert Unicode Zero Width Space characters just before (or after) the slashes in the HTML.
After some research for translation between Linux and Windows formats of the file paths in XML files I found interesting tutorials and solutions on:
To detect and locate memory leaks for long running processes, e.g. in production environments, you can now use stackimpact. It uses tracemalloc underneath. More info in this post.
I actually had the same problem with a completely new repository. I had even tried creating one with git checkout -b master
, but it would not create the branch. I then realized if I made some changes and committed them, git created my master branch.
For QT 5.* if you face error at Kits, like No Valid Kits Found
, go to Options->Build&Run-> (Kits tab) then you see a Manual category which should list Desktop as the default.
Just go to your OS Terminal and write sudo apt-get install qt5-default
, go back to QT Creator and Start your New Project, and there you see the kit option Desktop included in the list.
Try this command, it will purge all branches that have been merged to the develop

I found this question while trying to debug my mod_rewrite issues, and it definitely has some helpful advice. But in the end the most important thing is to make sure you have your regex syntax correct. Due to problems with my own RE syntax, installing the regexpCheck.php script was not a viable option.
But since Apache uses Perl-Compatible Regular Expressions (PCRE)s, any tool which helps writing PCREs should help. I've used RegexPlanet's tool with Java and Javascript REs in the past, and was happy to find that they support Perl as well.
Just type in your regular expression and one or more example URLs, and it will tell you if the regex matches (a "1" in the "~=" column) and if applicable, any matching groups (the numbers in the "split" column will correspond to the numbers Apache expects, e.g. $1, $2 etc.) for each URL. They claim PCRE support is "in beta", but it was just what I needed to solve my syntax problems.

I'd have simply added a comment to an existing answer but my reputation isn't yet at that level. Hope this helps someone.
You need to download log4j and add in your classpath.

I have added this function to a library I created
vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------
Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.
If you don't use jQuery
then the script would be something like this:
function posY(elm) {
var test = elm, top = 0;
while(!!test && test.tagName.toLowerCase() !== "body") {
top += test.offsetTop;
test = test.offsetParent;
}
return top;
}
function viewPortHeight() {
var de = document.documentElement;
if(!!window.innerWidth)
{ return window.innerHeight; }
else if( de && !isNaN(de.clientHeight) )
{ return de.clientHeight; }
return 0;
}
function scrollY() {
if( window.pageYOffset ) { return window.pageYOffset; }
return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}
function checkvisible( elm ) {
var vpH = viewPortHeight(), // Viewport Height
st = scrollY(), // Scroll Top
y = posY(elm);
return (y > (vpH + st));
}
Using jQuery is a lot easier:
function checkVisible( elm, evalType ) {
evalType = evalType || "visible";
var vpH = $(window).height(), // Viewport Height
st = $(window).scrollTop(), // Scroll Top
y = $(elm).offset().top,
elementHeight = $(elm).height();
if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
if (evalType === "above") return ((y < (vpH + st)));
}
This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.
See in action: http://jsfiddle.net/RJX5N/2/
I hope this answers your question.
-- IMPROVED VERSION--
This is a lot shorter and should do it as well:
function checkVisible(elm) {
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}
with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/
And a version with threshold
and mode
included:
function checkVisible(elm, threshold, mode) {
threshold = threshold || 0;
mode = mode || 'visible';
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
var above = rect.bottom - threshold < 0;
var below = rect.top - viewHeight + threshold >= 0;
return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}
and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/
I found a solution changing buildTypes like this:
buildTypes {
release {
signingConfig signingConfigs.release
}
}
1. Style parent element: style="display:flex; flex-direction:column; flex:1;"
2. Style the element you want to stay at bottom: style="margin-top: auto;"
3. Done! Wow. That was easy.
Example:
<section style="display:flex; flex-wrap:wrap;"> // For demo, not necessary
<div style="display:flex; flex-direction:column; flex:1;"> // Parent element
<button style="margin-top: auto;"> I </button> // Target element
</div>
... 5 more identical divs, for demo ...
</section>
Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point
Right click on your project
Properties > Configuration Properties > Linker > System
Select Console (/SUBSYSTEM:CONSOLE) in SubSystem
option or you can just type Console in the text field!
Now try it...it should work
I wasn't quite sure where I would store the start position, so I want to elaborate on David Boikes comment. I found that I could store that variable in the ui.item object itself and retrieve it in the stop function as so:
$( "#sortable" ).sortable({
start: function(event, ui) {
ui.item.startPos = ui.item.index();
},
stop: function(event, ui) {
console.log("Start position: " + ui.item.startPos);
console.log("New position: " + ui.item.index());
}
});
I have encountered this with Maven projects too. This is what I had to do to get around the problem:
First update your web.xml
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>Servlet 3.0 Web Application</display-name>
Then right click on your project and select Properties -> Project Facets In there you will see the version of your Dynamic Web Module. This needs to change from version 2.3 or whatever to version 2.5 or above (I chose 3.0).
However to do this I had to uncheck the tick box for Dynamic Web Module -> Apply, then do a Maven Update on the project. Go back into the Project Facets window and it should already match your web.xml configuration - 3.0 in my case. You should be able to change it if not.
If this does not work for you then try right-clicking on the Dynamic Web Module Facet and select change version (and ensure it is not locked).
Or you can follow this steps:
don't forget to update your project
Hope that works!
This error will also occur when using pdsh to hosts which are not contained in your "known_hosts" file.
I was able to correct this by SSH'ing into each host manually and accepting the question "Do you want to add this to known hosts".
This worked for me :
select option {
color: black;
}
select:not(:checked) {
color: gray;
}
You can use literal:
this.Controls.Add(new LiteralControl("<script type='text/javascript'>myFunction();</script>"));
I have resolved this problem to add some change like git add -A and git commit again.
I use such alias in my .bashrc config
alias gpb='git push origin `git rev-parse --abbrev-ref HEAD`'
On the command $gpb
it takes the current branch name and pushes it to the origin.
Here are my other aliases:
alias gst='git status'
alias gbr='git branch'
alias gca='git commit -am'
alias gco='git checkout'
Although it might look out of topic nobody bothered to check the ERRORLEVEL. When I used your suggestions I tried to check for errors straight after the MSI installation. I made it fail on purpose and noticed that on the command line all works beautifully whilst in a batch file msiexec dosn't seem to set errors. Tried different things there like
Nothing works and what mostly annoys me it's the fact that it works in the command line.
A simple way to use modals is with eModal!
Ex from github:
<script src="//rawgit.com/saribe/eModal/master/dist/eModal.min.js"></script>
use eModal to display a modal for alert, ajax, prompt or confirm
// Display an alert modal with default title (Attention)
eModal.alert('You shall not pass!');

Whilst the accepted answer works and is good for Linq to Objects it bugged me that the SQL query isn't just a straight Left Outer Join.
The following code relies on the LinkKit Project that allows you to pass expressions and invoke them to your query.
static IQueryable<TResult> LeftOuterJoin<TSource,TInner, TKey, TResult>(
this IQueryable<TSource> source,
IQueryable<TInner> inner,
Expression<Func<TSource,TKey>> sourceKey,
Expression<Func<TInner,TKey>> innerKey,
Expression<Func<TSource, TInner, TResult>> result
) {
return from a in source.AsExpandable()
join b in inner on sourceKey.Invoke(a) equals innerKey.Invoke(b) into c
from d in c.DefaultIfEmpty()
select result.Invoke(a,d);
}
It can be used as follows
Table1.LeftOuterJoin(Table2, x => x.Key1, x => x.Key2, (x,y) => new { x,y});
I think you must use rawurlencode() instead urlencode() for your purpose.
sample
$image = 'some images.jpg';
$url = 'http://example.com/'
With urlencode($str) will result
echo $url.urlencode($image); //http://example.com/some+images.jpg
its not change to %20 at all
but with rawurlencode($image) will produce
echo $url.rawurlencode(basename($image)); //http://example.com/some%20images.jpg
Serialization systems other than the native java one can also use this modifier. Hibernate, for instance, will not persist fields marked with either @Transient or the transient modifier. Terracotta as well respects this modifier.
I believe the figurative meaning of the modifier is "this field is for in-memory use only. don't persist or move it outside of this particular VM in any way. Its non-portable". i.e. you can't rely on its value in another VM memory space. Much like volatile means you can't rely on certain memory and thread semantics.
TLS 1.2
is only supported since OpenSSL 1.0.1
(see the Major version releases section), you have to update your OpenSSL
.
It is not necessary to set the CURLOPT_SSLVERSION
option. The request involves a handshake which will apply the newest TLS
version both server and client support. The server you request is using TLS 1.2
, so your php_curl
will use TLS 1.2
(by default) as well if your OpenSSL
version is (or newer than) 1.0.1
.
This query generates numbers from 0 to 1023. I believe it would work in any sql database flavor:
select
i0.i
+i1.i*2
+i2.i*4
+i3.i*8
+i4.i*16
+i5.i*32
+i6.i*64
+i7.i*128
+i8.i*256
+i9.i*512
as i
from
(select 0 as i union select 1) as i0
cross join (select 0 as i union select 1) as i1
cross join (select 0 as i union select 1) as i2
cross join (select 0 as i union select 1) as i3
cross join (select 0 as i union select 1) as i4
cross join (select 0 as i union select 1) as i5
cross join (select 0 as i union select 1) as i6
cross join (select 0 as i union select 1) as i7
cross join (select 0 as i union select 1) as i8
cross join (select 0 as i union select 1) as i9
Underscore.js is great for this kind of thing. You can use _.countBy()
to get the counts per name
:
data = [{"id":11,"name":"ajax","subject":"OR","mark":63},
{"id":12,"name":"javascript","subject":"OR","mark":63},
{"id":13,"name":"jquery","subject":"OR","mark":63},
{"id":14,"name":"ajax","subject":"OR","mark":63},
{"id":15,"name":"jquery","subject":"OR","mark":63},
{"id":16,"name":"ajax","subject":"OR","mark":63},
{"id":20,"name":"ajax","subject":"OR","mark":63}]
_.countBy(data, function(data) { return data.name; });
Gives:
{ajax: 4, javascript: 1, jquery: 2}
For an array of the keys just use _.keys()
_.keys(_.countBy(data, function(data) { return data.name; }));
Gives:
["ajax", "javascript", "jquery"]
Let me describe my situation.
First, check the current config
$ nvm use --delete-prefix v10.7.0
$ npm config list
Then, I found the error config in output:
; project config /mnt/c/Users/paul/.npmrc
prefix = "/mnt/c/Users/paul/C:\\Program Files\\nodejs"
So, I deleted the C:\\Program Files\\nodejs
in /mnt/c/Users/paul/.npmrc.
If you want to send your data inside the body, then you have to make a POST
or PUT
instead of GET
.
For me, it looks like you're trying to send the query with uri parameters, which is not related to GET
, you can also put these parameters on POST
, PUT
and so on.
The query is an optional part, separated by a question mark ("?"), that contains additional identification information that is not hierarchical in nature. The query string syntax is not generically defined, but it is commonly organized as a sequence of = pairs, with the pairs separated by a semicolon or an ampersand.
For example:
curl http://server:5050/a/c/getName?param0=foo¶m1=bar
In Python 2.x another approach is to use map
:
numbers = map(int, numbers)
Note: in Python 3.x map
returns a map object which you can convert to a list if you want:
numbers = list(map(int, numbers))
go to Run Configuration and in argument tab you can write your argument
You can use dictionary.map like this:
let myKeys: [String] = myDictionary.map{String($0.key) }
The explanation: Map iterates through the myDictionary and accepts each key and value pair as $0. From here you can get $0.key or $0.value. Inside the trailing closure {}, you can transform each element and return that element. Since you want $0 and you want it as a string then you convert using String($0.key). You collect the transformed elements to an array of strings.
Simply update with a convert/cast to INT:
UPDATE YOUR_TABLE
SET YOUR_COLUMN = CAST(YOUR_COLUMN AS INT)
WHERE -- some condition is met if required
Or convert:
UPDATE YOUR_TABLE
SET YOUR_COLUMN = CONVERT(INT, YOUR_COLUMN)
WHERE -- some condition is met if required
To test you can do this:
SELECT YOUR_COLUMN AS CurrentValue,
CAST(YOUR_COLUMN AS INT) AS NewValue
FROM YOUR_TABLE
Other that the differences in the default access (public/private), there is no difference.
However, some shops that code in C and C++ will use "class/struct" to indicate that which can be used in C and C++ (struct) and which are C++ only (class). In other words, in this style all structs must work with C and C++. This is kind of why there was a difference in the first place long ago, back when C++ was still known as "C with Classes."
Note that C unions work with C++, but not the other way around. For example
union WorksWithCppOnly{
WorksWithCppOnly():a(0){}
friend class FloatAccessor;
int a;
private:
float b;
};
And likewise
typedef union friend{
int a;
float b;
} class;
only works in C
here is the full program to make a POST rest call using spring's RestTemplate.
import java.util.HashMap;
import java.util.Map;
import org.springframework.http.HttpEntity;
import org.springframework.http.ResponseEntity;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;
import com.ituple.common.dto.ServiceResponse;
public class PostRequestMain {
public static void main(String[] args) {
// TODO Auto-generated method stub
MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
Map map = new HashMap<String, String>();
map.put("Content-Type", "application/json");
headers.setAll(map);
Map req_payload = new HashMap();
req_payload.put("name", "piyush");
HttpEntity<?> request = new HttpEntity<>(req_payload, headers);
String url = "http://localhost:8080/xxx/xxx/";
ResponseEntity<?> response = new RestTemplate().postForEntity(url, request, String.class);
ServiceResponse entityResponse = (ServiceResponse) response.getBody();
System.out.println(entityResponse.getData());
}
}
I'm not convinced that doing what you did fixes the problem; I think it masks yet another problem in your logic. To find the second highest is actually quite simple:
static int secondHighest(int... nums) {
int high1 = Integer.MIN_VALUE;
int high2 = Integer.MIN_VALUE;
for (int num : nums) {
if (num > high1) {
high2 = high1;
high1 = num;
} else if (num > high2) {
high2 = num;
}
}
return high2;
}
This is O(N)
in one pass. If you want to accept ties, then change to if (num >= high1)
, but as it is, it will return Integer.MIN_VALUE
if there aren't at least 2 elements in the array. It will also return Integer.MIN_VALUE
if the array contains only the same number.
I've taken your code and adapted it with library react-form-with-constraints: https://codepen.io/tkrotoff/pen/LLraZp
const {
FormWithConstraints,
FieldFeedbacks,
FieldFeedback
} = ReactFormWithConstraints;
class Form extends React.Component {
handleChange = e => {
this.form.validateFields(e.target);
}
contactSubmit = e => {
e.preventDefault();
this.form.validateFields();
if (!this.form.isValid()) {
console.log('form is invalid: do not submit');
} else {
console.log('form is valid: submit');
}
}
render() {
return (
<FormWithConstraints
ref={form => this.form = form}
onSubmit={this.contactSubmit}
noValidate>
<div className="col-md-6">
<input name="name" size="30" placeholder="Name"
required onChange={this.handleChange}
className="form-control" />
<FieldFeedbacks for="name">
<FieldFeedback when="*" />
</FieldFeedbacks>
<input type="email" name="email" size="30" placeholder="Email"
required onChange={this.handleChange}
className="form-control" />
<FieldFeedbacks for="email">
<FieldFeedback when="*" />
</FieldFeedbacks>
<input name="phone" size="30" placeholder="Phone"

First off, it might not be good to just go by recall alone. You can simply achieve a recall of 100% by classifying everything as the positive class. I usually suggest using AUC for selecting parameters, and then finding a threshold for the operating point (say a given precision level) that you are interested in.
For how class_weight
works: It penalizes mistakes in samples of class[i]
with class_weight[i]
instead of 1. So higher class-weight means you want to put more emphasis on a class. From what you say it seems class 0 is 19 times more frequent than class 1. So you should increase the class_weight
of class 1 relative to class 0, say {0:.1, 1:.9}.
If the class_weight
doesn't sum to 1, it will basically change the regularization parameter.
For how class_weight="auto"
works, you can have a look at this discussion.
In the dev version you can use class_weight="balanced"
, which is easier to understand: it basically means replicating the smaller class until you have as many samples as in the larger one, but in an implicit way.
I was also struggling with a similar issue dealing with exporting data into an Excel spreadsheet using C#. I tried many different methods working with external DLLs and had no luck.
For the export functionality you do not need to use anything dealing with the external DLLs. Instead, just maintain the header and content type of the response.
Here is an article that I found rather helpful. The article talks about how to export data to Excel spreadsheets using ASP.NET.
http://www.icodefor.net/2016/07/export-data-to-excel-sheet-in-asp-dot-net-c-sharp.html
try this
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string = dateFormat.format(new Date());
System.out.println(string);
you can create any format see this
I suggest you use a wrapper div or paragraph:
<td><p style="width:50%;">Text only allowed to extend 50% of the cell.</p></td>
And you can make a class out of it:
<td class="linebreak"><p>Text only allowed to extend 50% of the cell.</p></td>
td.linebreak p {
width: 50%;
}
All of this assuming that you meant 50% as in 50% of the cell.
Use JSON classes for parsing e.g
JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");
JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....
Add double quote
$nameRegex = "chalmw-dm*"
-like "$nameregex"
or -like "'$nameregex'"
GoodNews from v.9.6 and above, View editing are now native from psql. Just invoke \ev
command. View definitions will show in your configured editor.
julian@assange=# \ev {your_view_names}
Bonus. Some useful command to interact with query buffer.
Query Buffer
\e [FILE] [LINE] edit the query buffer (or file) with external editor
\ef [FUNCNAME [LINE]] edit function definition with external editor
\ev [VIEWNAME [LINE]] edit view definition with external editor
\p show the contents of the query buffer
\r reset (clear) the query buffer
\s [FILE] display history or save it to file
\w FILE write query buffer to file
toString()
only returns the exception name and the optional message. I would suggest calling
exception.printStackTrace()
to dump the message, or if you need the gory details:
StackTraceElement[] trace = exception.getStackTrace()
To simply explain the difference,
response.sendRedirect("login.jsp");
doesn't prepend the contextpath (refers to the application/module in which the servlet is bundled)
but, whereas
request.getRequestDispathcer("login.jsp").forward(request, response);
will prepend the contextpath of the respective application
Furthermore, Redirect request is used to redirect to resources to different servers or domains. This transfer of control task is delegated to the browser by the container. That is, the redirect sends a header back to the browser / client. This header contains the resource url to be redirected by the browser. Then the browser initiates a new request to the given url.
Forward request is used to forward to resources available within the server from where the call is made. This transfer of control is done by the container internally and browser / client is not involved.
It all depends what type of operation you are doing while iterating , all data structures have trade off between time and memory and depending on our needs we should choose the right DS. So there are some cases where LinkedList are faster then array and vice versa . Consider the three basic operation on data structures.
Since array is index based data structure searching array.get(index) will take O(1) time while linkedlist is not index DS so you will need to traverse up to index , where index <=n , n is size of linked list , so array is faster the linked list when have random access of elements.
Q.So what's the beauty behind this ?
As Arrays are contiguous memory blocks, large chunks of them will be loaded into the cache upon first access this makes it comparatively quick to access remaining elements of the array,as much as we access the elements in array locality of reference also increases thus less catch misses, Cache locality refers to the operations being in the cache and thus execute much faster as compared to in memory,basically In array we maximize the chances of sequential element access being in the cache. While Linked lists aren't necessarily in contiguous blocks of memory, there's no guarantee that items which appear sequentially in the list are actually arranged near each-other in memory, this means fewer cache hits e.g. more cache misses because we need to read from memory for every access of linked list element which increases the time it takes to access them and degraded performance so if we are doing more random access operation aka searching , array will be fast as explained below.
This is easy and fast in LinkedList as insertion is O(1) operation in LinkedList (in Java) as compared to array, consider the case when array is full, we need to copy contents to new array if array gets full which makes inserting an element into ArrayList of O(n) in worst case, while ArrayList also needs to update its index if you insert something anywhere except at the end of array , in case of linked list we needn't to be resize it, you just need to update pointers.
It works like insertions and better in LinkedList than array.
INTERSECT
needs to be emulated in MySQL
:
SELECT 'robot' AS `set`, r.*
FROM robot r
WHERE ROW(r.col1, r.col2, …) NOT IN
(
SELECT col1, col2, ...
FROM tbd_robot
)
UNION ALL
SELECT 'tbd_robot' AS `set`, t.*
FROM tbd_robot t
WHERE ROW(t.col1, t.col2, …) NOT IN
(
SELECT col1, col2, ...
FROM robot
)
I found deleting the contents of node_modules and performing npm install
again worked for me.
Instead of attempting to do a right click on a mouse use the keyboard shortcut:
Double click on the element -> hold shift and press F10.
Actions action = new Actions(driver);
//Hold left shift and press F10
action.MoveToElement(element).DoubleClick().KeyDown(Keys.LeftShift).SendKeys(Keys.F10).KeyUp(Keys.LeftShift).Build().Perform();
If you use same color for whole program , you can define printf()
function.
#include<stdio.h>
#define ah_red "\e[31m"
#define printf(X) printf(ah_red "%s",X);
#int main()
{
printf("Bangladesh");
printf("\n");
return 0;
}
Consider the below sample code snippet which demonstrates how to dismiss a dialog fragment safely:
DialogFragment dialogFragment = new DialogFragment();
/**
* do something
*/
// Now you want to dismiss the dialog fragment
if (dialogFragment.getDialog() != null && dialogFragment.getDialog().isShowing())
{
// Dismiss the dialog
dialogFragment.dismiss();
}
Happy Coding!
You can include the user and password as part of the URL:

of course, you'll need the username password, it's not 'Basic hashstring
.

To make an exact spacing, I use Padding
. An example with two images:
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Expanded(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Image.asset('images/user1.png'),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Image.asset('images/user2.png'),
),
)
],
),
Yes it's the exact same thing in Python 2:
d.values()
In Python 3 (where dict.values
returns a view of the dictionary’s values instead):
list(d.values())
C doesn't have a foreach, but macros are frequently used to emulate that:
#define for_each_item(item, list) \
for(T * item = list->head; item != NULL; item = item->next)
And can be used like
for_each_item(i, processes) {
i->wakeup();
}
Iteration over an array is also possible:
#define foreach(item, array) \
for(int keep = 1, \
count = 0,\
size = sizeof (array) / sizeof *(array); \
keep && count != size; \
keep = !keep, count++) \
for(item = (array) + count; keep; keep = !keep)
And can be used like
int values[] = { 1, 2, 3 };
foreach(int *v, values) {
printf("value: %d\n", *v);
}
Edit: In case you are also interested in C++ solutions, C++ has a native for-each syntax called "range based for"
public void GetResponseAsync (HttpWebRequest request, Action<HttpWebResponse> gotResponse)

HttpWebResponse response = request.EndGetResponse (r);
if (gotResponse != null)
gotResponse (response);
} catch (Exception x) {
Console.WriteLine ("Unable to get response for '" + request.RequestUri + "' Err: " + x);
}
}, null);
}
}
You can configure patterns to hide files and folders from the explorer and searches.
Open VS User Settings (Main menu: File > Preferences > Settings). This will open the setting screen.
Search for files:exclude
in the search at the top.
Configure the User Setting with new glob patterns as needed. In this case, add this pattern node_modules/ then click OK. The pattern syntax is powerful. You can find pattern matching details under the Search Across Files topic.

If you are creating the TableModel automatically from a set of values (with "new JTable(Vector, Vector)"), perhaps it is easier to remove editors from columns:
JTable table = new JTable(my_rows, my_header);
for (int c = 0; c < table.getColumnCount(); c++)
{
Class<?> col_class = table.getColumnClass(c);
table.setDefaultEditor(col_class, null); // remove editor
}
Without editors, data will be not editable.
You can add an IBAction to the uiTextField(the releation event is "Did End On Exit"),and the IBAction may named hideKeyboard,
-(IBAction)hideKeyboard:(id)sender
{
[uitextfield resignFirstResponder];
}
also,you can apply it to the other textFields or buttons,for example,you may add a hidden button to the view,when you click it to hide the keyboard.

It means maven is not able to download artifacts from repository. Following steps will help you:
Your best bet would be to anticipate prefixes, so:
"(|(displayName=SEARCHKEY*)(displayName=ITSM - SEARCHKEY*)(displayName=alt prefix - SEARCHKEY*))"
Clunky, but I'm doing a similar thing within my organization.
This is code I used in Windows. It works.
for item in COOKIES.split(';'):
name,value = item.split('=', 1)
name=name.replace(' ', '').replace('\r', '').replace('\n', '')
value = value.replace(' ', '').replace('\r', '').replace('\n', '')
cookie_dict={
'name':name,
'value':value,
"domain": "", # Google Chrome
"expires": "",
'path': '/',
'httpOnly': False,
'HostOnly': False,
'Secure': False
}
self.driver_.add_cookie(cookie_dict)
You already attempt to filter out NULL
values with NOT NULL
. I have changed this to IS NOT NULL
in the WHERE
clause so it will execute. We can refactor this by removing the ISNULL
function in the AVG
method. Also, I doubt you'll actually need bigint
so we can remove the cast.
SELECT distinct
AVG(a.SecurityW) as Average1
,AVG(a.TransferW) as Average2
,AVG(a.StaffW) as Average3
FROM Table1 a, Table2 b
WHERE a.SecurityW <> 0 AND a.SecurityW IS NOT NULL
AND a.TransferW<> 0 AND a.TransferWIS IS NOT NULL
AND a.StaffW<> 0 AND a.StaffWIS IS NOT NULL
AND MONTH(a.ActualTime) = 4
AND YEAR(a.ActualTime) = 2013
Best Practice - use singular. You have a list of items that make up an Enum. Using an item in the list sounds strange when you say Versions.1_0
. It makes more sense to say Version.1_0
since there is only one 1_0 Version.
This is known as varargs see the link here for more details
In past java releases, a method that took an arbitrary number of values required you to create an array and put the values into the array prior to invoking the method. For example, here is how one used the MessageFormat class to format a message:
Object[] arguments = {
new Integer(7),
new Date(),
"a disturbance in the Force"
};
String result = MessageFormat.format(
"At {1,time} on {1,date}, there was {2} on planet "
+ "{0,number,integer}.", arguments);
It is still true that multiple arguments must be passed in an array, but the varargs feature automates and hides the process. Furthermore, it is upward compatible with preexisting APIs. So, for example, the MessageFormat.format method now has this declaration:
public static String format(String pattern,
Object... arguments);
I wrote a library that can help with type convertions https://github.com/KromDaniel/jonson
js := jonson.New([]interface{}{55.6, 70.8, 10.4, 1, "48", "-90"})
js.SliceMap(func(jsn *jonson.JSON, index int) *jonson.JSON {
jsn.MutateToInt()
return jsn
}).SliceMap(func(jsn *jonson.JSON, index int) *jonson.JSON {
if jsn.GetUnsafeInt() > 50{
jsn.MutateToString()
}
return jsn
}) // ["55","70",10,1,48,-90]
You can use the Path
api:
Path p = Paths.get(yourFileNameUri);
Path folder = p.getParent();
Just include Better-Dom and Better-Dateinput-Polyfill in your scripts section.
Here is a Demo:
http://chemerisuk.github.io/better-dateinput-polyfill/
Here is a simple solution that works at least for me. It's probably not the fastest though because it uses the cool DateTime's AddMonth feature in a loop:
public static int GetMonthsDiff(DateTime start, DateTime end)
{
if (start > end)
return GetMonthsDiff(end, start);
int months = 0;
do
{
start = start.AddMonths(1);
if (start > end)
return months;
months++;
}
while (true);
}
Simple ways to check an empty dict are below:
a= {}
1. if a == {}:
print ('empty dict')
2. if not a:
print ('empty dict')
Although method 1st is more strict as when a = None, method 1 will provide correct result but method 2 will give an incorrect result.
If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.
You can simply use:
List<string> items = new List<string>() { "foo", "boo", "john", "doe" };
Console.WriteLine(string.Join(",", items));
Happy coding!
df.dropna(subset=['columnName1', 'columnName2'])

.OrderBy(group => group.Key)
.Select(group => Tuple.Create(group.Key, group.Count()));
REST is tightly coupled with HTTP, so if you only expose your API over HTTP then REST is more appropriate for most (but not all) situations. However, if you need to expose your API over other transports like messaging or web sockets then REST is just not applicable.
This is changed in Java 6 update 18.
Assuming that we have more than 1 GB of physical memory (quite common these days), it's always 1/4th of your physical memory for the server vm.
//This is without test
NSMutableCharacterSet* set = [[NSCharacterSet alphanumericCharacterSet] mutableCopy];
[set addCharactersInString:@"-_.~"];
NSString *encode = [test stringByAddingPercentEncodingWithAllowedCharacters:set];
I had an error with an array getting the max and the min so my solution was:
int max = Arrays.stream(arrayWithInts).max().getAsInt();

I fixed this problem by following the solution to this other StackOverflow question
I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below: (Please note the https protocol)
- Open Window > Preferences
- Open Maven > Archetypes
- Click 'Add Remote Catalog' and add the following:
- Catalog File: https://repo1.maven.org/maven2/archetype-catalog.xml
- Description: maven catalog
I did something like this. I passed "fragmentType" and created two ViewHolders
and on basis of this, i classified my Layouts accordingly in a single adapter that can have different Layouts
and LayoutManagers
private Context mContext;
protected IOnLoyaltyCardCategoriesItemClicked mListener;
private String fragmentType;
private View view;
public LoyaltyCardsCategoriesRecyclerViewAdapter(Context context, IOnLoyaltyCardCategoriesItemClicked itemListener, String fragmentType) {
this.mContext = context;
this.mListener = itemListener;
this.fragmentType = fragmentType;
}
public class LoyaltyCardCategoriesFragmentViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private ImageView lc_categories_iv;
private TextView lc_categories_name_tv;
private int pos;
public LoyaltyCardCategoriesFragmentViewHolder(View v) {
super(v);
view.setOnClickListener(this);
lc_categories_iv = (ImageView) v.findViewById(R.id.lc_categories_iv);
lc_categories_name_tv = (TextView) v.findViewById(R.id.lc_categories_name_tv);
}
public void setData(int pos) {
this.pos = pos;
lc_categories_iv.setImageResource(R.mipmap.ic_launcher);
lc_categories_name_tv.setText("Loyalty Card Categories");
}
@Override
public void onClick(View view) {
if (mListener != null) {
mListener.onLoyaltyCardCategoriesItemClicked(pos);
}
}
}
public class MyLoyaltyCardsFragmentTagViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public ImageButton lc_categories_btn;
private int pos;
public MyLoyaltyCardsFragmentTagViewHolder(View v) {
super(v);
lc_categories_btn = (ImageButton) v.findViewById(R.id.lc_categories_btn);
lc_categories_btn.setOnClickListener(this);
}
public void setData(int pos) {
this.pos = pos;
lc_categories_btn.setImageResource(R.mipmap.ic_launcher);
}
@Override
public void onClick(View view) {
if (mListener != null) {
mListener.onLoyaltyCardCategoriesItemClicked(pos);
}
}
}
@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (fragmentType.equalsIgnoreCase(Constants.LoyaltyCardCategoriesFragmentTag)) {
view = LayoutInflater.from(mContext).inflate(R.layout.loyalty_cards_categories_frag_item, parent, false);
return new LoyaltyCardCategoriesFragmentViewHolder(view);
} else if (fragmentType.equalsIgnoreCase(Constants.MyLoyaltyCardsFragmentTag)) {
view = LayoutInflater.from(mContext).inflate(R.layout.my_loyalty_cards_categories_frag_item, parent, false);
return new MyLoyaltyCardsFragmentTagViewHolder(view);
} else {
return null;
}
}
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
if (fragmentType.equalsIgnoreCase(Constants.LoyaltyCardCategoriesFragmentTag)) {
((LoyaltyCardCategoriesFragmentViewHolder) holder).setData(position);
} else if (fragmentType.equalsIgnoreCase(Constants.MyLoyaltyCardsFragmentTag)) {
((MyLoyaltyCardsFragmentTagViewHolder) holder).setData(position);
}
}
@Override

Here is a fully functional example of what you are trying to accomplish. I created the example inside of hyperdev rather than jsFiddle so that you could see the server-side and client-side code.
View Code: https://hyperdev.com/#!/project/destiny-authorization
View Working Application: https://destiny-authorization.hyperdev.space/
This code creates a handler for a get request that returns a random string:
app.get("/string", function(req, res) {
var strings = ["string1", "string2", "string3"]
var n = Math.floor(Math.random() * strings.length)
res.send(strings[n])
});
This jQuery code then makes the ajax request and receives the random string from the server.
$.get("/string", function(string) {
$('#txtString').val(string);
});
Note that this example is based on code from Jamund Ferguson's answer so if you find this useful be sure to upvote him as well. I just thought this example would help you to see how everything fits together.
Actually, I think the problem is that your variable "lines" is bad. You defined lines as a tuple, but I believe that write() requires a string. All you have to change is your commas into pluses (+).
nl = "\n"
lines = line1+nl+line2+nl+line3+nl
textdoc.writelines(lines)
should work.
You should use NMAP:
nmap -T5 -sP 192.168.0.0-255
It actually happend to me because I mistakenly named the source file "something.c" instead of "something.cpp". I hope this helps someone who has the same error.
Easy
$('<img src=>')[0].src
Generates a img with empty src-name forces the browser to calculate the base-url by itself, no matter if you have /index.html
or anything else.
I will show you a whole example of servlet & how do ajax call.
Here, we are going to create the simple example to create the login form using servlet.
index.html
<form>
Name:<input type="text" name="username"/><br/><br/>
Password:<input type="password" name="userpass"/><br/><br/>
<input type="button" value="login"/>
</form>
Here is ajax Sample
$.ajax
({
type: "POST",
data: 'LoginServlet='+name+'&name='+type+'&pass='+password,
url: url,
success:function(content)
{
$('#center').html(content);
}
});
LoginServlet Servlet Code :-
package abc.servlet;
import java.io.File;
public class AuthenticationServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
doPost(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
try{
HttpSession session = request.getSession();
String username = request.getParameter("name");
String password = request.getParameter("pass");
/// Your Code
out.println("sucess / failer")
} catch (Exception ex) {
// System.err.println("Initial SessionFactory creation failed.");
ex.printStackTrace();
System.exit(0);
}
}
}
