Try this:
[https://lodash.com/docs/4.17.4#clone][1]
var objects = [{ 'a': 1 }, { 'b': 2 }];
var shallow = _.clone(objects);
console.log(shallow[0] === objects[0]);
// => true
The easiest way is simply to pay attention to the order in which the Views are added to your XML file. Lower down in the file means higher up in the Z-axis.
Edit: This is documented here and here on the Android developer site. (Thanks @flightplanner)
For Jupyter and Windows users, you can change the Target path in your Jupyter Notebook (anaconda3)
shortcut from C:\Users\<YourUserName>\anaconda3
to C:\Users\<YourUserName>\anaconda3\envs\<YourEnvironmentName>
you could do the same thing for the Anaconda Prompt..etc.
After changing the path you can check your active environment by opening a terminal in Jupyter and run conda info --envs
.
Images have display: inline
by default.
You might want to put the image inside the paragraph.
<p><img /></p>
You want border-spacing
:
<table style="border-spacing: 10px;">
Or in a CSS block somewhere:
table {
border-spacing: 10px;
}
See quirksmode on border-spacing
. Be aware that border-spacing
does not work on IE7 and below.
Node.js does not run in a browser, therefore you will not have a document
object available. Actually, you will not even have a DOM tree at all. If you are a bit confused at this point, I encourage you to read more about it before going further.
There are a few methods you can choose from to do what you want.
Because you wrote about opening the file in the browser, why don't you use a framework that will serve the file directly as an HTTP service, instead of having a two-step process? This way, your code will be more dynamic and easily maintainable (not mentioning your HTML always up-to-date).
There are plenty frameworks out there for that :
The most basic way you could do what you want is this :
var http = require('http');
http.createServer(function (req, res) {
var html = buildHtml(req);
res.writeHead(200, {
'Content-Type': 'text/html',
'Content-Length': html.length,
'Expires': new Date().toUTCString()
});
res.end(html);
}).listen(8080);
function buildHtml(req) {
var header = '';
var body = '';
// concatenate header string
// concatenate body string
return '<!DOCTYPE html>'
+ '<html><head>' + header + '</head><body>' + body + '</body></html>';
};
And access this HTML with http://localhost:8080
from your browser.
(Edit: you could also serve them with a small HTTP server.)
If what you are trying to do is simply generating some HTML files, then go simple. To perform IO access on the file system, Node has an API for that, documented here.
var fs = require('fs');
var fileName = 'path/to/file';
var stream = fs.createWriteStream(fileName);
stream.once('open', function(fd) {
var html = buildHtml();
stream.end(html);
});
Note: The buildHtml
function is exactly the same as in Method 1.
stdout
This is the most basic Node.js implementation and requires the invoking application to handle the output itself. To output something in Node (ie. to stdout), the best way is to use console.log(message)
where message
is any string, or object, etc.
var html = buildHtml();
console.log(html);
Note: The buildHtml
function is exactly the same as in Method 1 (again)
If your script is called html-generator.js
(for example), in Linux/Unix based system, simply do
$ node html-generator.js > path/to/file
Because Node is a modular system, you can even put the buildHtml
function inside it's own module and simply write adapters to handle the HTML however you like. Something like
var htmlBuilder = require('path/to/html-builder-module');
var html = htmlBuilder(options);
...
You have to think "server-side" and not "client-side" when writing JavaScript for Node.js; you are not in a browser and/or limited to a sandbox, other than the V8 engine.
Extra reading, learn about npm. Hope this helps.
This is tested in android 7.0 up to android 10.0 and it works
Use these codes to check if string contains space/spaces may it be in the first position, middle or last:
name = firstname.getText().toString(); //name is the variable that holds the string value
Pattern space = Pattern.compile("\\s+");
Matcher matcherSpace = space.matcher(name);
boolean containsSpace = matcherSpace.find();
if(constainsSpace == true){
//string contains space
}
else{
//string does not contain any space
}
import java.util.Scanner;
public class SumAll {
public static void sumAll(int arr[]) {//initialize method return sum
int sum = 0;
for (int i = 0; i < arr.length; i++) {
sum += arr[i];
}
System.out.println("Sum is : " + sum);
}
public static void main(String[] args) {
int num;
Scanner input = new Scanner(System.in);//create scanner object
System.out.print("How many # you want to add : ");
num = input.nextInt();//return num from keyboard
int[] arr2 = new int[num];
for (int i = 0; i < arr2.length; i++) {
System.out.print("Enter Num" + (i + 1) + ": ");
arr2[i] = input.nextInt();
}
sumAll(arr2);
}
}
You're already doing it correctly, it just that the <h4>Facebook</h4>
tag is taking too much vertical margin. You can remove it by using the style margin:0px
on the <h4>
tag.
For your future convenience, you can put border (border:1px solid black
) on your elements to see which part you actually get it wrong.
window.location.href
returns the location of the current page.
top.location.href
(which is an alias of window.top.location.href
) returns the location of the topmost window in the window hierarchy. If a window has no parent, top
is a reference to itself (in other words, window
=== window.top
).
top
is useful both when you're dealing with frames and when dealing with windows which have been opened by other pages. For example, if you have a page called test.html
with the following script:
var newWin=window.open('about:blank','test','width=100,height=100');
newWin.document.write('<script>alert(top.location.href);</script>');
The resulting alert will have the full path to test.html – not about:blank, which is what window.location.href
would return.
To answer your question about redirecting, go with window.location.assign(url);
Please read the $.ajax
documentation, this is a covered topic.
$.ajax({
url: "test.html",
error: function(){
// will fire when timeout is reached
},
success: function(){
//do something
},
timeout: 3000 // sets timeout to 3 seconds
});
You can get see what type of error was thrown by accessing the textStatus parameter of the error: function(jqXHR, textStatus, errorThrown)
option. The options are "timeout", "error", "abort", and "parsererror".
@Multipart
@POST(Config.UPLOAD_IMAGE)
Observable<Response<String>> uploadPhoto(@Header("Access-Token") String header, @Part MultipartBody.Part imageFile);
And you can call this api like this:
public void uploadImage(File file) {
// create multipart
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);
// upload
getViewInteractor().showProfileUploadingProgress();
Observable<Response<String>> observable = api.uploadPhoto("",body);
// on Response
subscribeForNetwork(observable, new ApiObserver<Response<String>>() {
@Override
public void onError(Throwable e) {
getViewInteractor().hideProfileUploadingProgress();
}
@Override
public void onResponse(Response<String> response) {
if (response.code() != 200) {
Timber.d("error " + response.code());
return;
}
getViewInteractor().hideProfileUploadingProgress();
getViewInteractor().onProfileImageUploadSuccess(response.body());
}
});
}
Try following code;
DropDownList1.Items.Add(new ListItem(txt_box1.Text));
Unfortunately you cannot.
I tried using the CSS max
function in padding
to attempt this functionality, but I got a parse error in my css. Below is what I tried:
padding: 5px max(50vw - 350px, 10vw);
I then tried to separate the operations into variables, and that didn't work either
--padding: calc(50vw - 350px);
--max-padding: max(1vw, var(--padding));
padding: 5px var(--max-padding);
What eventually worked was just nesting what I wanted padded in a div with class "centered" and using max width and width like so
.centered {
width: 98vw;
max-width: 700px;
height: 100%;
margin: 0 auto;
}
Unfortunately, this appears to be the best way to mimic a "max-padding" and "min-padding". I imagine the technique would be similar for "min-margin" and "max-margin". Hopefully this gets added at some point!
//create TreeMap instance
TreeMap treeMap = new TreeMap();
//add key value pairs to TreeMap
treeMap.put("1","One");
treeMap.put("2","Two");
treeMap.put("3","Three");
/*

Collection c = treeMap.values();
//obtain an Iterator for Collection
Iterator itr = c.iterator();
//iterate through TreeMap values iterator
while(itr.hasNext())
System.out.println(itr.next());
or:
for (Map.Entry<K,V> entry : treeMap.entrySet()) {
V value = entry.getValue();
K key = entry.getKey();
}
or:
// Use iterator to display the keys and associated values
System.out.println("Map Values Before: ");
Set keys = map.keySet();
for (Iterator i = keys.iterator(); i.hasNext();) {
Integer key = (Integer) i.next();
String value = (String) map.get(key);
System.out.println(key + " = " + value);
}
studying the above answers almost worked for me ... but I still had a problem that I could 'fling' the view on 2.1 (seemed to be fixed with 2.2 & 2.3).
here is my final solution
public class MyWebView extends WebView
{
private boolean bAllowScroll = true;
@SuppressWarnings("unused") // it is used, just java is dumb
private long downtime;
public MyWebView(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public void setAllowScroll(int allowScroll)
{
bAllowScroll = allowScroll!=0;
if (!bAllowScroll)
super.scrollTo(0,0);
setHorizontalScrollBarEnabled(bAllowScroll);
setVerticalScrollBarEnabled(bAllowScroll);
}
@Override
public boolean onTouchEvent(MotionEvent ev)
{
switch (ev.getAction())
{
case MotionEvent.ACTION_DOWN:
if (!bAllowScroll)
downtime = ev.getEventTime();
break;
case MotionEvent.ACTION_CANCEL:
case MotionEvent.ACTION_UP:
if (!bAllowScroll)
{
try {
Field fmNumSamples = ev.getClass().getDeclaredField("mNumSamples");
fmNumSamples.setAccessible(true);
Field fmTimeSamples = ev.getClass().getDeclaredField("mTimeSamples");
fmTimeSamples.setAccessible(true);
long newTimeSamples[] = new long[fmNumSamples.getInt(ev)];
newTimeSamples[0] = ev.getEventTime()+250;
fmTimeSamples.set(ev,newTimeSamples);
} catch (Exception e) {
e.printStackTrace();
}
}
break;
}
return super.onTouchEvent(ev);
}
@Override
public void flingScroll(int vx, int vy)
{
if (bAllowScroll)
super.flingScroll(vx,vy);
}
@Override

You use attach
without detach
- every time you do it new call to attach masks objects attached before (they contain the same names). Either use detach
or do not use attach
at all.
Nice discussion and tips are here.
You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.
Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.
Here is a working code I have written for you:
https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27
In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.
I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file):
Percentage (%) = 100 x partial value / total value
It automatically calculates the total and pourcentage even if you add more categories.
I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:
var trace1 = {
x: xValue,
y: data,
type: 'bar',
text: yValue,
textposition: 'auto',
hoverinfo: 'none',
marker: {
color: 'yellow',
opacity: 0.6,
line: {
color: 'yellow',
width: 1.5
}
}
};
It is rather self explanatory, the text
is where you put the percentage.
Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:
I know it is an old post but I hope it helps people with the same problem !
Disclosure : I’m a developer of funfun
To dynamically change the color of a text box goto properties, goto font/Color and set the following expression
=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)
Same way for tolerance
=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")
inplace=True
is used depending if you want to make changes to the original df or not.
df.drop_duplicates()
will only make a view of dropped values but not make any changes to df
df.drop_duplicates(inplace = True)
will drop values and make changes to df.
Hope this helps.:)
I don't know R at all, but a bit of creative googling led me here: http://tolstoy.newcastle.edu.au/R/help/05/04/1919.html
The key quote from there:
I do not find explicit documentation for R on how to remove elements from lists, but trial and error tells me
myList[[5]] <- NULL
will remove the 5th element and then "close up" the hole caused by deletion of that element. That suffles the index values, So I have to be careful in dropping elements. I must work from the back of the list to the front.
A response to that post later in the thread states:
For deleting an element of a list, see R FAQ 7.1
And the relevant section of the R FAQ says:
... Do not set x[i] or x[[i]] to NULL, because this will remove the corresponding component from the list.
Which seems to tell you (in a somewhat backwards way) how to remove an element.
Hope that helps, or at least leads you in the right direction.
If you're not sure whether the object has been disposed or not, you should call the Dispose
method itself rather than methods such as Close
. While the framework doesn't guarantee that the Dispose method must run without exceptions even if the object had previously been disposed, it's a common pattern and to my knowledge implemented on all disposable objects in the framework.
The typical pattern for Dispose
, as per Microsoft:
public void Dispose()
{
Dispose(true);
// Use SupressFinalize in case a subclass
// of this type implements a finalizer.
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
// If you need thread safety, use a lock around these
// operations, as well as in your methods that use the resource.
if (!_disposed)
{
if (disposing) {
if (_resource != null)
_resource.Dispose();
Console.WriteLine("Object disposed.");
}
// Indicate that the instance has been disposed.
_resource = null;
_disposed = true;
}
}
Notice the check on _disposed
. If you were to call a Dispose
method implementing this pattern, you could call Dispose as many times as you wanted without hitting exceptions.
There are extra square brackets in the command you tried.
To install the latest version from the v1
branch, you can use:
npm install git://github.com/shakacode/bootstrap-loader.git#v1 --save
Try to never use relative paths. Use a generic include where you assign the DocumentRoot server variable to a global variable, and construct absolute paths from there. Alternatively, for larger projects, consider implementing a PSR-0 SPL autoloader.
How did you try it? Maybe you are working with \
and omit proper escaping.
Instead of
open('\\HOST\share\path\to\file')
use either Johnsyweb's solution with the /
s, or try one of
open(r'\\HOST\share\path\to\file')
or
open('\\\\HOST\\share\\path\\to\\file')
.
-To compare only the date part, you can do:
var result = db.query($"SELECT * FROM table WHERE date >= '{fromDate.ToString("yyyy-MM-dd")}' and date <= '{toDate.ToString("yyyy-MM-dd"}'");

If you already have the data "for (Parcelable currentHeadline : allHeadlines)," then why are you doing that in a separate thread?
You should poll the data in a separate thread, and when it's finished gathering it, then call your populateTables method on the UI thread:
private void populateTable() {
runOnUiThread(new Runnable(){
public void run() {
//If there are stories, add them to the table
for (Parcelable currentHeadline : allHeadlines) {
addHeadlineToTable(currentHeadline);
}
try {
dialog.dismiss();
} catch (final Exception ex) {
Log.i("---","Exception in thread");
}
}
});
}
If you need to add two strings you have to use the '+' operator
hence
msg['Subject'] = 'your string' + sys.argv[1]
and also you have to import sys in the beginning
as
import sys
msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]
When you want to create interval store promise to variable:
var p = $interval(function() { ... },1000);
And when you want to stop / clear the interval simply use:
$interval.cancel(p);
i it integer, int to Integer
Integer intObj = new Integer(i);
add to collection
list.add(String.valueOf(intObj));
This answer if for the people experiencing the same problem trying to accessing the camera.
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
# Capture frame-by-frame
ret, frame = cap.read()
# Our operations on the frame come here
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# Display the resulting frame
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
Using Linux:
if you are trying to access the camera from your computer most likely there is a permission issue, try running the python script with sudo it should fix it.
sudo python python_script.py
To test if the camera is accessible run the following command.
ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 output.mkv
Let's talk in from company concept. Log gives you flexible levels (see Difference between logger.info and logger.debug). Different people want to see different levels, like QAs, developers, business people. But e.printStackTrace() will print out everything. Also, like if this method will be restful called, this same error may print several times. Then the Devops or Tech-Ops people in your company may be crazy because they will receive the same error reminders.
I think a better replacement could be log.error("errors happend in XXX", e)
This will also print out whole information which is easy reading than e.printStackTrace()
As we can read here (Peter Gulutzan) there is difference on sorting/comparing polish letter "L" (L with stroke - html esc: Ł
) (lower case: "l" - html esc: ł
) - we have following assumption:
utf8_polish_ci L greater than L and less than M
utf8_unicode_ci L greater than L and less than M
utf8_unicode_520_ci L equal to L
utf8_general_ci L greater than Z
In polish language letter L
is after letter L
and before M
. No one of this coding is better or worse - it depends of your needs.
Newer versions of Groovy (1.7.2+) offer a JDK extension to more easily traverse over files in a directory, for example:
import static groovy.io.FileType.FILES
def dir = new File(".");
def files = [];
dir.traverse(type: FILES, maxDepth: 0) { files.add(it) };
See also [1] for more examples.

You could start your php script from the command line (i.e. bash) by using
nohup php myscript.php &
the &
puts your process in the background.
Edit:
Yes, there are some drawbacks, but not possible to control? That's just wrong.
A simple kill processid
will stop it. And it's still the best and simplest solution.
In my case I had added a project to a solution manually, where that project was targeting a higher .NET version than the rest of the projects that were referencing it. Strange... there would normally be a somewhat more verbose, literal and descriptive error in such cases.
There wasn't a real error but there was a warning that said as much.
1.If I have something like Foo o = new Foo(); inside the method, does that mean that each time the timer ticks, I'm creating a new object and a new reference to that object?
Yes.
2.If I have string foo = null and then I just put something temporal in foo, is it the same as above?
If you are asking if the behavior is the same then yes.
3.Does the garbage collector ever delete the object and the reference or objects are continually created and stay in memory?
The memory used by those objects is most certainly collected after the references are deemed to be unused.
4.If I just declare Foo o; and not point it to any instance, isn't that disposed when the method ends?
No, since no object was created then there is no object to collect (dispose is not the right word).
5.If I want to ensure that everything is deleted, what is the best way of doing it
If the object's class implements IDisposable
then you certainly want to greedily call Dispose
as soon as possible. The using
keyword makes this easier because it calls Dispose
automatically in an exception-safe way.
Other than that there really is nothing else you need to do except to stop using the object. If the reference is a local variable then when it goes out of scope it will be eligible for collection.1 If it is a class level variable then you may need to assign null
to it to make it eligible before the containing class is eligible.
1This is technically incorrect (or at least a little misleading). An object can be eligible for collection long before it goes out of scope. The CLR is optimized to collect memory when it detects that a reference is no longer used. In extreme cases the CLR can collect an object even while one of its methods is still executing!
Update:
Here is an example that demonstrates that the GC will collect objects even though they may still be in-scope. You have to compile a Release build and run this outside of the debugger.
static void Main(string[] args)
{
Console.WriteLine("Before allocation");
var bo = new BigObject();
Console.WriteLine("After allocation");
bo.SomeMethod();
Console.ReadLine();
// The object is technically in-scope here which means it must still be rooted.
}
private class BigObject
{
private byte[] LotsOfMemory = new byte[Int32.MaxValue / 4];
public BigObject()
{
Console.WriteLine("BigObject()");
}
~BigObject()
{
Console.WriteLine("~BigObject()");
}
public void SomeMethod()
{
Console.WriteLine("Begin SomeMethod");
GC.Collect();
GC.WaitForPendingFinalizers();
Console.WriteLine("End SomeMethod");
}
}
On my machine the finalizer is run while SomeMethod
is still executing!
sudo apt-get install libpng-dev libjpeg8-dev libfreetype6-dev
worked for me on Ubuntu 14.04
It happened to me when I accidentally left the build in release mode.
Sorry to bump an old question but the answer is to count the character length of the cell and not its value.
CellCount = Cells(Row, 10).Value
If Len(CellCount) <= "13" Then
'do something
End If
hope that helps. Cheers
Here are two pitfalls in iOS 8.3 when coming with textView.textContainer.maximumNumberOfLines = 10
Refer to my gist, please.
textView.attributedText = originalContent
let lineLimit = 10
textView.isEditable = true
textView.isScrollEnabled = false
textView.textContainerInset = .zero // default is (8, 0, 8, 0)
textView.textContainer.maximumNumberOfLines = lineLimit // Important condition
textView.textContainer.lineBreakMode = .byTruncatingTail
// two incomplete methods, which do NOT work in iOS 8.3
// size.width???maxSize.width? ————???? iOS 8.3 ??????maximumNumberOfLines??,??????UILabel
// size.width may be less than maxSize.width, ---- Do NOT work in iOS 8.3, which disregards textView.textContainer.maximumNumberOfLines
// let size = textView.sizeThatFits(maxSize)
// ???? iOS 8.3 ???????,????UILabel
// Does not work in iOS 8.3
// let size = textView.layoutManager.usedRectForTextContainer(textView.textContainer).size
// Suggested method: use a temperary label to get its size
let label = UILabel(); label.attributedText = originalContent
let size = label.textRect(forBounds: CGRect(origin: .zero, size: maxSize), limitedToNumberOfLines: lineLimit).size
textView.frame.size = size
The --no-ff
flag prevents git merge
from executing a "fast-forward" if it detects that your current HEAD
is an ancestor of the commit you're trying to merge. A fast-forward is when, instead of constructing a merge commit, git just moves your branch pointer to point at the incoming commit. This commonly occurs when doing a git pull
without any local changes.
However, occasionally you want to prevent this behavior from happening, typically because you want to maintain a specific branch topology (e.g. you're merging in a topic branch and you want to ensure it looks that way when reading history). In order to do that, you can pass the --no-ff
flag and git merge
will always construct a merge instead of fast-forwarding.
Similarly, if you want to execute a git pull
or use git merge
in order to explicitly fast-forward, and you want to bail out if it can't fast-forward, then you can use the --ff-only
flag. This way you can regularly do something like git pull --ff-only
without thinking, and then if it errors out you can go back and decide if you want to merge or rebase.
In general, the key to avoiding an explicit loop would be to join (merge) 2 instances of the dataframe on rowindex-1==rowindex.
Then you would have a big dataframe containing rows of r and r-1, from where you could do a df.apply() function.
However the overhead of creating the large dataset may offset the benefits of parallel processing...
Problem solved!

I think there is an unwritten rule (something like a convention) that says to use 'alias' just for registering a method-name alias, means if you like to give the user of your code one method with more than one name:
class Engine
def start
#code goes here
end
alias run start
end
If you need to extend your code, use the ruby meta alternative.
class Engine
def start
puts "start me"
end
end
Engine.new.start() # => start me
Engine.class_eval do
unless method_defined?(:run)
alias_method :run, :start
define_method(:start) do
puts "'before' extension"
run()
puts "'after' extension"
end
end
end
Engine.new.start
# => 'before' extension
# => start me
# => 'after' extension
Engine.new.run # => start me
The easiest way would be to use regular expression.
The other way is to find the position of the string with strpos() and then an substr_replace()
But i would really go for the RegExp.
I've tried this in Python 3.6.9
>>> hours, minutes, seconds = 9, 33, 35
>>> time = f'{hours:02}:{minutes:02}:{seconds:02} {"pm" if hours > 12 else "am"}'
>>> print (time)
09:33:35 am
>>> type(time)
<class 'str'>
You're running your Python 3 code with a Python 2 interpreter. If you weren't, your print
statement would throw up a SyntaxError
before it ever prompted you for input.
The result is that you're using Python 2's input
, which tries to eval
your input (presumably sdas
), finds that it's invalid Python, and dies.

Here is a technique which seems to work around the edge cases: the end of the year and leap Februaries.
The problem with datediff(year,…,…)
is that it only finds the difference between the years, and not the actual dates, which is a bit naïve in my opinion. This is only reliable if the date of birth is 1st Jan.
The solution is to time warp the date of birth to the first of January, and the asking date by the same amount.
Because of the leap year problem using the day of year is also unreliable, so I use the month and day to do the time warp:
CREATE FUNCTION age(@then AS date,@now AS date) RETURNS int AS
BEGIN
DECLARE @month INT = month(@then)-1;
DECLARE @day INT = day(@then)-1;
SET @then=dateadd(month,-@month,@then);
SET @then=dateadd(day,-@day,@then);
SET @now=dateadd(month,-@month,@now;)
SET @now=dateadd(day,-@day,@now);
RETURN datediff(year,@then,@now);
END;
You can write this more compactly, of course. You can even write it in one line, if that’s your idea of having a good time:
CREATE FUNCTION age(@then AS date,@now AS date) RETURNS int AS
BEGIN
RETURN datediff(
year,
dateadd(day,-day(@then)+1,dateadd(month,-month(@then)+1,@then)),
dateadd(day,-day(@then)+1,dateadd(month,-month(@then)+1,@now))
);
END;
but that’s only showing off, and it’s less efficient as it needs to recalculate the offsets.
This works for me
.print+.print {
page-break-before: always;

Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.
In the case the first arg is '-v', then do your conditional ps -ef
, else in all other cases throw the usage.
#!/bin/sh
case $1 in
'-v') if [ "$1" = -v ]; then
echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
fi;;
*) echo "usage: $0 [-v]"
exit 1;; #It is good practice to throw a code, hence allowing $? check
esac
If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.
#!/bin/sh
usage ()
{
echo "usage: $0 [-v]"
exit 1
}
unset arg_match
for arg in $*
do
case $arg in
'-v') if [ "$arg" = -v ]; then
echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
fi
arg_match=1;; # this is set, but could increment.
*) ;;
esac
done
if [ ! $arg_match ]
then
usage
fi
But, allow multiple occurrences of an argument is convenient to use in situations such as:
$ adduser -u:sam -s -f -u:bob -trace -verbose
We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:
$ adduser -u sam -s -f -u bob -trace -verbose
Try something like this:
$link = @new mysqli($this->host, $this->user, $this->pass)
$statement = $link->prepare($sqlStatement);
if(!$statement)
{
$this->debug_mode('query', 'error', '#Query Failed<br/>' . $link->error);
return false;
}
Does this work?

Your function would work like this:
CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS
$$
BEGIN
RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;
END
$$ LANGUAGE plpgsql;
Call:
SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)
You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.
The aggregate function count()
returns bigint
, but you had rowcount
defined as integer
, so you need an explicit cast ::int
to make this work
I use dollar quoting to avoid quoting hell.
However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.
Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)
The query itself seems rather odd, btw. But that's beside the point here.
I had this same issue in SQL Server and wrote this T-SQL script to automate the process (actually this is the watered-down version, mine wrote all the diff to a single table for easy reporting).
Update 'MyTable' and 'MyOtherTable' to the names of the tables you wish to compare.
DECLARE @ColName varchar(100)
DECLARE @Table1 varchar(100) = 'MyTable'
DECLARE @Table2 varchar(100) = 'MyOtherTable'
IF (OBJECT_ID('tempdb..#col') IS NOT NULL) DROP TABLE #col
SELECT IDENTITY(INT, 1, 1) RowNum , c.name
INTO #col
FROM SYS.Objects o
JOIN SYS.columns c on o.object_id = c.object_id
WHERE o.name = @Table1 AND NOT c.Name IN ('List','Columns','YouWantToIgnore')
DECLARE @Counter INT = (SELECT MAX(RowNum) FROM #col)
WHILE @Counter > 0
BEGIN
SET @ColName = (SELECT name FROM #Col WHERE RowNum= @Counter)
EXEC ('SELECT t1.Identifier
,t1.'+@ColName+' AS '+@Table1+@ColName+'
,t2.'+@ColName+' AS '+@Table2+@ColName+'
FROM '+@Table1+' t1
LEFT JOIN '+@Table2+' t2 ON t1.Identifier = t2.Identifier
WHERE t1.'+@ColName+' <> t2.'+@ColName)
SET @Counter = @Counter - 1
END
This can also be done as follows. Put your commands in a script, let's name it commands-inc.sh
#!/bin/bash
ls some_folder
./someaction.sh
pwd
Save the file
Now run it on the remote server.
ssh user@remote 'bash -s' < /path/to/commands-inc.sh
Never failed for me.
What solved my issue was creating a file startmongo.conf that sets the bind_ip to 127.0.0.1 . After that, I just created a *.bat to start the mongo using something like:
mongod --config c:\mongodb\bin\startmongo.conf
tl;dr: use OSX's native process launcher and manager, launchd
.
To do so, make a launchctl
daemon. You'll have full control over all aspects of the script. You can run once or keep alive as a daemon. In most cases, this is the way to go.
.plist
file according to the instructions in the Apple Dev docs here or more detail below.~/Library/LaunchAgents
launchctl load [filename.plist]
)For more on launchd
, the wikipedia article is quite good and describes the system and its advantages over other older systems.
Here's the specific plist file to run a script at login.
Updated 2017/09/25 for OSX El Capitan and newer (credit to José Messias Jr):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.user.loginscript</string>
<key>ProgramArguments</key>
<array><string>/path/to/executable/script.sh</string></array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
Replace the <string>
after the Program key with your desired command (note that any script referenced by that command must be executable: chmod a+x /path/to/executable/script.sh
to ensure it is for all users).
Save as ~/Library/LaunchAgents/com.user.loginscript.plist
Run launchctl load ~/Library/LaunchAgents/com.user.loginscript.plist
and log out/in to test (or to test directly, run launchctl start com.user.loginscript
)
Tail /var/log/system.log
for error messages.
The key is that this is a User-specific launchd entry, so it will be run on login for the given user. System-specific launch daemons (placed in /Library/LaunchDaemons
) are run on boot.
If you want a script to run on login for all users, I believe LoginHook is your only option, and that's probably the reason it exists.
If you have a typical table structure with an auto-incrementing primary key column in which rows are never deleted, the following will be the fastest way to determine the record count and should work similarly across most ANSI compliant databases:
SELECT TOP(1) <primarykeyfield> FROM <table> ORDER BY <primarykeyfield> DESC;
I work with MS SQL tables containing billions of rows that require sub-second response times for data, including record counts. A similar SELECT COUNT(*) would take minutes to process by comparison.
If you are floating the elements you can reverse the order
i.e. float: right;
instead of float: left;
And then use this method to select the first-child of a class.
/* 1: Apply style to ALL instances */
#header .some-class {
padding-right: 0;
}
/* 2: Remove style from ALL instances except FIRST instance */
#header .some-class~.some-class {
padding-right: 20px;
}
This is actually applying the class to the LAST instance only because it's now in reversed order.
Here is a working example for you:
<!doctype html>
<head><title>CSS Test</title>
<style type="text/css">
.some-class { margin: 0; padding: 0 20px; list-style-type: square; }
.lfloat { float: left; display: block; }
.rfloat { float: right; display: block; }
/* apply style to last instance only */
#header .some-class {
border: 1px solid red;
padding-right: 0;
}
#header .some-class~.some-class {
border: 0;
padding-right: 20px;
}
</style>
</head>
<body>
<div id="header">
<img src="some_image" title="Logo" class="lfloat no-border"/>
<ul class="some-class rfloat">
<li>List 1-1</li>
<li>List 1-2</li>
<li>List 1-3</li>
</ul>
<ul class="some-class rfloat">
<li>List 2-1</li>
<li>List 2-2</li>
<li>List 2-3</li>
</ul>
<ul class="some-class rfloat">
<li>List 3-1</li>
<li>List 3-2</li>
<li>List 3-3</li>
</ul>
<img src="some_other_img" title="Icon" class="rfloat no-border"/>
</div>

Thx guys, I finally found the solution, a really basic one.. In my controller I have
$scope.mySplit = function(string, nb) {
var array = string.split(',');
return array[nb];
}
and in my view
{{mySplit(string,0)}}
Here is the focus listener example.
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean hasFocus) {
if (hasFocus) {
Toast.makeText(getApplicationContext(), "Got the focus", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Lost the focus", Toast.LENGTH_LONG).show();
}
}
});
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

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;
SELECT TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') FROM EmpTable;
First the bigint(20) not null auto_increment
will not work, simply use bigserial primary key
. Then datetime
is timestamp
in PostgreSQL. All in all:
CREATE TABLE article (
article_id bigserial primary key,
article_name varchar(20) NOT NULL,
article_desc text NOT NULL,
date_added timestamp default NULL
);

In PHP5, you should use the Document Object Model class instead. Example:
$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);
$subElt = $domDoc->createElement('foo');
$attr = $domDoc->createAttribute('ah');
$attrVal = $domDoc->createTextNode('OK');
$attr->appendChild($attrVal);
$subElt->appendChild($attr);
$subNode = $rootNode->appendChild($subElt);
$textNode = $domDoc->createTextNode('Wow, it works!');
$subNode->appendChild($textNode);
echo htmlentities($domDoc->saveXML());
In the parent process, fork()'s return value is the process ID of the child process. Stuff that value away somewhere for when you need to terminate the child process. fork() returns zero(0) in the child process.
When you need to terminate the child process, use the kill(2) function with the process ID returned by fork(), and the signal you wish to deliver (e.g. SIGTERM).
Remember to call wait() on the child process to prevent any lingering zombies.
Different web stacks do support different lengths of http-requests. I know from experience that the early stacks of Safari only supported 4000 characters and thus had difficulty handling ASP.net pages because of the USER-STATE. This is even for POST, so you would have to check the browser and see what the stack limit is. I think that you may reach a limit even on newer browsers. I cannot remember but one of them (IE6, I think) had a limit of 16-bit limit, 32,768 or something.
If your instance is called SQLEXPRESS

exec 3>&1 1>>${LOG_FILE} 2>&1
would send stdout and stderr output into the log file, but would also leave you with fd 3 connected to the console, so you can do
echo "Some console message" 1>&3
to write a message just to the console, or
echo "Some console and log file message" | tee /dev/fd/3
to write a message to both the console and the log file - tee
sends its output to both its own fd 1 (which here is the LOG_FILE
) and the file you told it to write to (which here is fd 3, i.e. the console).
Example:
exec 3>&1 1>>${LOG_FILE} 2>&1
echo "This is stdout"
echo "This is stderr" 1>&2
echo "This is the console (fd 3)" 1>&3
echo "This is both the log and the console" | tee /dev/fd/3
would print
This is the console (fd 3)
This is both the log and the console
on the console and put
This is stdout
This is stderr
This is both the log and the console
into the log file.
The three top-rated answers have a weakness.
If your dataframe looks like this
df <- data.frame(Time=c(1,2), In=c(2,3), Out=c(3,4), Files=c(4,5))
> df
Time In Out Files
1 1 2 3 4
2 2 3 4 5
then it's a poor solution to use
> df2[,c(1,3,2,4)]
It does the job, but you have just introduced a dependence on the order of the columns in your input.
This style of brittle programming is to be avoided.
The explicit naming of the columns is a better solution
data[,c("Time", "Out", "In", "Files")]
Plus, if you intend to reuse your code in a more general setting, you can simply
out.column.name <- "Out"
in.column.name <- "In"
data[,c("Time", out.column.name, in.column.name, "Files")]
which is also quite nice because it fully isolates literals. By contrast, if you use dplyr's select
data <- data %>% select(Time, out, In, Files)
then you'd be setting up those who will read your code later, yourself included, for a bit of a deception. The column names are being used as literals without appearing in the code as such.
MySQL will truncate any insert value that exceeds the specified column width.
to make this without error try switch your SQL mode
to not use STRICT
.
To change the mode
This can be done in two ways:
my.ini
(Windows) or my.cnf
(Unix) file within the MySQL installation directory, and look for the text "sql-mode".Find:
Code:
# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
Replace with:
Code:
# Set the SQL mode to strict
sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
Or
Code:
SET @@global.sql_mode= '';

using dynamic variable in C# is the simplest.
Newtonsoft.Json.Linq has class JValue that can be used. Below is a sample code which displays Question id and text from the JSON string you have.
string jsonString = "[{\"Question\":{\"QuestionId\":49,\"QuestionText\":\"Whats your name?\",\"TypeId\":1,\"TypeName\":\"MCQ\",\"Model\":{\"options\":[{\"text\":\"Rahul\",\"selectedMarks\":\"0\"},{\"text\":\"Pratik\",\"selectedMarks\":\"9\"},{\"text\":\"Rohit\",\"selectedMarks\":\"0\"}],\"maxOptions\":10,\"minOptions\":0,\"isAnswerRequired\":true,\"selectedOption\":\"1\",\"answerText\":\"\",\"isRangeType\":false,\"from\":\"\",\"to\":\"\",\"mins\":\"02\",\"secs\":\"04\"}},\"CheckType\":\"\",\"S1\":\"\",\"S2\":\"\",\"S3\":\"\",\"S4\":\"\",\"S5\":\"\",\"S6\":\"\",\"S7\":\"\",\"S8\":\"\",\"S9\":\"Pratik\",\"S10\":\"\",\"ScoreIfNoMatch\":\"2\"},{\"Question\":{\"QuestionId\":51,\"QuestionText\":\"Are you smart?\",\"TypeId\":3,\"TypeName\":\"True-False\",\"Model\":{\"options\":[{\"text\":\"True\",\"selectedMarks\":\"7\"},{\"text\":\"False\",\"selectedMarks\":\"0\"}],\"maxOptions\":10,\"minOptions\":0,\"isAnswerRequired\":false,\"selectedOption\":\"3\",\"answerText\":\"\",\"isRangeType\":false,\"from\":\"\",\"to\":\"\",\"mins\":\"01\",\"secs\":\"04\"}},\"CheckType\":\"\",\"S1\":\"\",\"S2\":\"\",\"S3\":\"\",\"S4\":\"\",\"S5\":\"\",\"S6\":\"\",\"S7\":\"True\",\"S8\":\"\",\"S9\":\"\",\"S10\":\"\",\"ScoreIfNoMatch\":\"2\"}]";

You can use the Series.to_list
method.
For example:
import pandas as pd
df = pd.DataFrame({'a': [1, 3, 5, 7, 4, 5, 6, 4, 7, 8, 9],
'b': [3, 5, 6, 2, 4, 6, 7, 8, 7, 8, 9]})
print(df['a'].to_list())
Output:
[1, 3, 5, 7, 4, 5, 6, 4, 7, 8, 9]
To drop duplicates you can do one of the following:
>>> df['a'].drop_duplicates().to_list()
[1, 3, 5, 7, 4, 6, 8, 9]
>>> list(set(df['a'])) # as pointed out by EdChum
[1, 3, 4, 5, 6, 7, 8, 9]
Function for set corner radius programmatically
static void setCornerRadius(GradientDrawable drawable, float topLeft,
float topRight, float bottomRight, float bottomLeft) {
drawable.setCornerRadii(new float[] { topLeft, topLeft, topRight, topRight,
bottomRight, bottomRight, bottomLeft, bottomLeft });
}
static void setCornerRadius(GradientDrawable drawable, float radius) {
drawable.setCornerRadius(radius);
}
Using
GradientDrawable gradientDrawable = new GradientDrawable();
gradientDrawable.setColor(Color.GREEN);
setCornerRadius(gradientDrawable, 20f);
//or setCornerRadius(gradientDrawable, 20f, 40f, 60f, 80f);
view.setBackground(gradientDrawable);
I had same issue and this solution didn't work but what worked was to use html
$('#your_textarea_id').html('some_value');
From the Maven docs, sounds like it's just a difference in which repository you install the package into:
Maybe there is some confusion in that "install" to the CI server installs it to it's local repository, which then you as a user are sharing?
You can do it using Linked Server.
Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel.
Linked servers offer the following advantages:
Read more about Linked Servers.
Server Objects -> Linked Servers -> New Linked Server
Provide Remote Server Name.
Select Remote Server Type (SQL Server or Other).
Select Security -> Be made using this security context and provide login and password of remote server.
Click OK and you are done !!
Here is a simple tutorial for creating a linked server.
OR
You can add linked server using query.
Syntax:
sp_addlinkedserver [ @server= ] 'server' [ , [ @srvproduct= ] 'product_name' ]
[ , [ @provider= ] 'provider_name' ]
[ , [ @datasrc= ] 'data_source' ]
[ , [ @location= ] 'location' ]
[ , [ @provstr= ] 'provider_string' ]
[ , [ @catalog= ] 'catalog' ]
Read more about sp_addlinkedserver.
You have to create linked server only once. After creating linked server, we can query it as follows:
select * from LinkedServerName.DatabaseName.OwnerName.TableName
There are a few attributes you should check: android:lines, android:minLines, android:maxLines. To display a maximum of 4 lines and ellipsize it, you just need android:maxLines and android:ellipsize:
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:maxLines="4"
android:ellipsize="marquee"
android:text="Hai!"
/>
Where is this info kept ("this connection is between computer
A
and serverF
")?
A TCP connection is recognized by source IP and port and destination IP and port. Your OS, all intermediate session-aware devices and the server's OS will recognize the connection by this.
HTTP works with request-response: client connects to server, performs a request and gets a response. Without keep-alive, the connection to an HTTP server is closed after each response. With HTTP keep-alive you keep the underlying TCP connection open until certain criteria are met.
This allows for multiple request-response pairs over a single TCP connection, eliminating some of TCP's relatively slow connection startup.
When The IIS (F) sends keep alive header (or user sends keep-alive) , does it mean that (E,C,B) save a connection
No. Routers don't need to remember sessions. In fact, multiple TCP packets belonging to same TCP session need not all go through same routers - that is for TCP to manage. Routers just choose the best IP path and forward packets. Keep-alive is only for client, server and any other intermediate session-aware devices.
which is only for my session ?
Does it mean that no one else can use that connection
That is the intention of TCP connections: it is an end-to-end connection intended for only those two parties.
If so - does it mean that keep alive-header - reduce the number of overlapped connection users ?
Define "overlapped connections". See HTTP persistent connection for some advantages and disadvantages, such as:
if so , for how long does the connection is saved to me ? (in other words , if I set keep alive- "keep" till when?)
An typical keep-alive response looks like this:
Keep-Alive: timeout=15, max=100
See Hypertext Transfer Protocol (HTTP) Keep-Alive Header for example (a draft for HTTP/2 where the keep-alive header is explained in greater detail than both 2616 and 2086):
A host sets the value of the timeout
parameter to the time that the host will allows an idle connection to remain open before it is closed. A connection is idle if no data is sent or received by a host.
The max
parameter indicates the maximum number of requests that a client will make, or that a server will allow to be made on the persistent connection. Once the specified number of requests and responses have been sent, the host that included the parameter could close the connection.
However, the server is free to close the connection after an arbitrary time or number of requests (just as long as it returns the response to the current request). How this is implemented depends on your HTTP server.
If the DataFrame happens to have an Index or MultiIndex and you want those included as column names too:
names = list(filter(None, df.index.names + df.columns.values.tolist()))
It avoids calling reset_index() which has an unnecessary performance hit for such a simple operation.
I've run into needing this more often because I'm shuttling data from databases where the dataframe index maps to a primary/unique key, but is really just another "column" to me. It would probably make sense for pandas to have a built-in method for something like this (totally possible I've missed it).

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.
You can return an array, an object literal, or an object of a type you created that encapsulates the returned values.
Then you can pass in the array, object literal, or custom object into a method to disseminate the values.
Object example:
function myFunction(value1,value2,value3)
{
var returnedObject = {};
returnedObject["value1"] = value1;
returnedObject["value2"] = value2;
return returnedObject;
}
var returnValue = myFunction("1",value2,value3);
if(returnValue.value1 && returnValue.value2)
{
//Do some stuff
}
Array example:
function myFunction(value1,value2,value3)
{
var returnedArray = [];
returnedArray.push(value1);
returnedArray.push(value2);
return returnedArray;
}
var returnValue = myFunction("1",value2,value3);
if(returnValue[0] && returnValue[1])
{
//Do some stuff
}
Custom Object:
function myFunction(value1,value2,value3)
{
var valueHolder = new ValueHolder(value1, value2);
return valueHolder;
}
var returnValue = myFunction("1",value2,value3);
// hypothetical method that you could build to create an easier to read conditional
// (might not apply to your situation)
if(returnValue.valid())
{
//Do some stuff
}
I would avoid the array method because you would have to access the values via indices rather than named object properties.
This is what Wikipedia says about finally clause:
More common is a related clause (finally, or ensure) that is executed whether an exception occurred or not, typically to release resources acquired within the body of the exception-handling block.
Let's dissect your program.
try {
System.out.print(1);
q();
}
So, 1
will be output into the screen, then q()
is called. In q()
, an exception is thrown. The exception is then caught by Exception y
but it does nothing. A finally clause is then executed (it has to), so, 3
will be printed to screen. Because (in method q()
there's an exception thrown in the finally clause, also q()
method passes the exception to the parent stack (by the throws Exception
in the method declaration) new Exception()
will be thrown and caught by catch ( Exception i )
, MyExc2
exception will be thrown (for now add it to the exception stack), but a finally in the main
block will be executed first.
So in,
catch ( Exception i ) {
throw( new MyExc2() );
}
finally {
System.out.print(2);
throw( new MyExc1() );
}
A finally clause is called...(remember, we've just caught Exception i
and thrown MyExc2
) in essence, 2
is printed on screen...and after the 2
is printed on screen, a MyExc1
exception is thrown. MyExc1
is handled by the public static void main(...)
method.
Output:
"132Exception in thread main MyExc1"
Lecturer is correct! :-)
In essence, if you have a finally in a try/catch clause, a finally will be executed (after catching the exception before throwing the caught exception out)
I highly suggest not to write the loop by hand. You will do that over and over again during the course of your programming career. People reading your code - that includes you - always have to invest time, even if it are just some seconds, to digest the meaning of the loop.
Instead reuse one of the available libraries providing code that does just that like StringUtils.repeat
from Apache Commons Lang:
StringUtils.repeat(' ', length);
That way you also do not have to bother about performance, thus all the gory details of StringBuilder
, Compiler optimisations etc. are hidden.
If the function would turn out as slow it would be a bug of the library.
With Java 11 it becomes even easier:
" ".repeat(length);

You can use JSON.stringify(object)
with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array))
, which is the following code (more detail can be found on this answer):
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
}
To make it more generic, you can override the JSON.stringify
function and you won't have to worry about it again, to do this, just paste this at the top of your page:
// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
};
var oldJSONStringify = JSON.stringify;
JSON.stringify = function(input){
return oldJSONStringify(convArrToObj(input));
};
})();
And now JSON.stringify
will accept arrays
or objects
! (link to jsFiddle with example)
Edit:
Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array)
always returns []
, which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify
with an object
):
(function(){
// Convert array to object
var convArrToObj = function(array){
var thisEleObj = new Object();
if(typeof array == "object"){
for(var i in array){
var thisEle = convArrToObj(array[i]);
thisEleObj[i] = thisEle;
}
}else {
thisEleObj = array;
}
return thisEleObj;
};
var oldJSONStringify = JSON.stringify;
JSON.stringify = function(input){
if(oldJSONStringify(input) == '[]')
return oldJSONStringify(convArrToObj(input));
else
return oldJSONStringify(input);
};
})();
It is also worth noting the sorted()
function:
for x in sorted(list):
print x
This returns a new, sorted version of a list without changing the original list.
You can use anycache to do the job for you. It considers all the details:
pickle
module to handle lambda
and all the nice
python features.Assuming you have a function myfunc
which creates the instance:
from anycache import anycache
class Company(object):
def __init__(self, name, value):
self.name = name
self.value = value
@anycache(cachedir='/path/to/your/cache')
def myfunc(name, value)
return Company(name, value)
Anycache calls myfunc
at the first time and pickles the result to a
file in cachedir
using an unique identifier (depending on the function name and its arguments) as filename.
On any consecutive run, the pickled object is loaded.
If the cachedir
is preserved between python runs, the pickled object is taken from the previous python run.
For any further details see the documentation
It would be best to just have the http content on https

Make sure that the selected DB is the one where the table is. I was running the Script on Master
. In my case, I had to switch to hr_db
.
Rookie mistake but, could help someone.
Two more options based on CSS Text Module Level 3 (instead of white-space-collapsing:discard
which had been dropped from the spec draft):
word-spacing: -100%;
In theory, it should do exactly what is needed — shorten whitespaces between 'words' by the 100% of the space character width, i.e. to zero. But seems not to work anywhere, unfortunately, and this feature is marked 'at risk' (it can be dropped from the specification, too).
word-spacing: -1ch;
It shortens the inter-word spaces by the width of the digit '0'. In a monospace font it should be exactly equal to the width of the space character (and any other character as well). This works in Firefox 10+, Chrome 27+, and almost works in Internet Explorer 9+.
If you are using CustomBinding then you would rather need to make changes in httptransport element. Set it as
<customBinding>
<binding ...>
...
<httpsTransport maxReceivedMessageSize="2147483647"/>
</binding>
</customBinding>
Padding around the collapsing div must be 0
Not necessarily simpler, but a different way, if you are more familiar with the re family.
import re, string
s = "string. With. Punctuation?" # Sample string
out = re.sub('[%s]' % re.escape(string.punctuation), '', s)
Try this code:
Bitmap bitmap = null;
File f = new File(_path);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
try {
bitmap = BitmapFactory.decodeStream(new FileInputStream(f), null, options);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
image.setImageBitmap(bitmap);
Here is another way you can get to the root of your website without hard coding the url:
var response = Request.CreateResponse(HttpStatusCode.Moved);
string fullyQualifiedUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority);
response.Headers.Location = new Uri(fullyQualifiedUrl);
Note: Will only work if both your MVC website and WebApi are on the same URL
I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:
home = System.getenv('HOME')
It helps to keep in mind that anything that works in pure Java will work in Gradle too.
The transmission delay is the amount of time required for the router to push out the packet.
The propagation delay, is the time it takes a bit to propagate from one router to the next.
the transmission and propagation delay are completely different! if denote the length of the packet by L bits, and denote the transmission rate of the link from first router to second router by R bits/sec. then transmission delay will be L/R. and this is depended to transmission rate of link and the length of packet.
then if denote the distance between two routers d and denote the propagation speed s, the propagation delay will be d/s. it is a function of the Distance between the two routers, but has no dependence to the packet's length or the transmission rate of the link.
If you are using vim in MAC OSX, unfortunately it comes with older verion, and not complied with clipboard options. Luckily, homebrew can easily solve this problem.
install vim:
brew install vim --with-lua --with-override-system-vim
install gui verion of vim:
brew install macvim --with-lua --with-override-system-vim
restart the terminal to take effect.
append the following line to ~/.vimrc
set clipboard=unnamed
now you can copy the line in vim withyy
and paste it system-wide.

I had similar problems. I was also confused by some solutions leaving me with different versions displaying for different users. If you have any problems at all, I would first check every account your using any implementation of node
Finally, this solution appears to solve this issue 100%, giving me the confidence that my versions were universal no matter what user privileges I wanted to use:
sudo yum update
sudo yum install build-essential checkinstall libssl-dev
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash
(sudo) nvm --version
(sudo) nvm ls-remote
(sudo) nvm install [version.number]
If you're still having a problem, next try looking inside your /usr/local/bin directory. If you find either a large binary document named node or a folder named npm, delete them.
rm /usr/local/bin/node
rm -r /usr/local/bin/npm
Personally, before I deleted those, two of my user accounts were using the latest version of node/npm installed correctly via nvm, while a third account of mine remained stubborn by still using a far older installation of both node and npm apparently located inside my /usr/local/bin/ directory. As soon as I deleted both of them with the two above commands, that problematic user account implicitly began running the correct installation, having all three accounts mutually the intended versions.
(Implemented while using Centos 7 Blank x64. Some source code used above was originally supplied by 'phoenixNAP Global IT services' 1)
You can't group by literals, only columns.
You are probably looking for something like this:
select
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1) as pathinfo,
qvalues.name,
qvalues.compound,
qvalues.rid
from batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where LEN(datapath)>4
group by pathinfo, qvalues.name, qvalues.compound
having rid!=MAX(rid)
First of all, you have to give that first expression a column name with as
. Then you have to specify the names of the columns in the group by expression.
No. There is no single reliable way and there will never be. Did you really think you could trust the client?
I also needed this once, and I did a check on the window title of the process. If it is the one you expect, you can be sure the application is running. The application I was checking needed some time for startup and this method worked fine for me.
var process = Process.Start("popup.exe");
while(process.MainWindowTitle != "Title")
{
Thread.Sleep(10);
}
For the record, be advised that all of the above is (still) true only if the AJAX call is made on the same domain. If you're looking into setting cookies on another domain using AJAX, you're opening a totally different can of worms. Reading cross-domain cookies does work, however (or at least the server serves them; whether your client's UA allows your code to access them is, again, a different topic; as of 2014 they do).
This is a part from a REST-Service I´ve written recently.
var select = $("#productSelect")
for (var prop in data) {
var option = document.createElement('option');
option.innerHTML = data[prop].ProduktName
option.value = data[prop].ProduktName;
select.append(option)
}
The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.
You can use concat:
In [11]: pd.concat([df1['c'], df2['c']], axis=1, keys=['df1', 'df2'])
Out[11]:
df1 df2
2014-01-01 NaN -0.978535
2014-01-02 -0.106510 -0.519239
2014-01-03 -0.846100 -0.313153
2014-01-04 -0.014253 -1.040702
2014-01-05 0.315156 -0.329967
2014-01-06 -0.510577 -0.940901
2014-01-07 NaN -0.024608
2014-01-08 NaN -1.791899
[8 rows x 2 columns]
The axis argument determines the way the DataFrames are stacked:
df1 = pd.DataFrame([1, 2, 3])
df2 = pd.DataFrame(['a', 'b', 'c'])
pd.concat([df1, df2], axis=0)
0
0 1
1 2
2 3
0 a
1 b
2 c
pd.concat([df1, df2], axis=1)
0 0
0 1 a
1 2 b
2 3 c
add style="clear:both;"
to the "adm" div
.
In Eclipse, go to Build Path, click "Add Library", select JRE System Library, click "Next", select option "Workspace default JRE(i)", and click "Finish".
This worked for me.
Try this one:
import java.text.DecimalFormat;
DecimalFormat df = new DecimalFormat("0000");
String c = df.format(9); // Output: 0009
String a = df.format(99); // Output: 0099
String b = df.format(999); // Output: 0999
You could use tabs instead of spaces between columns, and/or set maximum size for a column in format strings ...
I've had this happen on VS after I changed the file's line endings. Changing them back to Windows CR LF fixed the issue.
Java does not support multiple inheritance.
There are a few workarounds I can think of:
The first is aggregation: make a class that takes those two activities as fields.
The second is to use interfaces.
The third is to rethink your design: does it make sense for a Preferences
class to be both a PreferenceActivity
and an AbstractBillingActivity
?
I had to solve the same issue and this is what I used as solution.
To use this solution the source and destination table must be identical, and the must have an id unique and autoincrement in first table (so that the same id is never reused).
Lets say table1 and table2 have this structure
|id|field1|field2
You can make those two query :
INSERT INTO table2 SELECT * FROM table1 WHERE
DELETE FROM table1 WHERE table1.id in (SELECT table2.id FROM table2)
I believe Angular 6 has the BehaviorSubject object. My sample below is done using Angular 8 and will hopefully work for Angular 6 as well.
This method is a more "reactive" approach to the problem, and assumes you are using and are well versed in rxjs.
Assuming you are using an Observable in your parent component, the component that is used in your routing definition, then you should be able to just pulse the data stream pretty easily.
My example also assumes you are using a view model in your component like so...
vm$: Observable<IViewModel>;
And in the HTML like so...
<div *ngIf="(vm$ | async) as vm">
In your component file, add a BehaviorSubject instance...
private refreshBs: BehaviorSubject<number> = new BehaviorSubject<number>(0);
Then also add an action that can be invoked by a UI element...
refresh() {
this.refreshBs.next(1);
}
Here's the UI snippet, a Material Bootstrap button...
<button mdbBtn color="primary" class="ml-1 waves-dark" type="button" outline="true"
(click)="refresh()" mdbWavesEffect>Refresh</button>
Then, in your ngOnIt function do something like this, keep in mind that my example is simplified a bit so that I don't have to provide a lot of code...
ngOnInit() {
this.vm$ = this.refreshBs.asObservable().pipe(
switchMap(v => this.route.queryParamMap),
map(qpm => qpm.get("value")),
tap(v => console.log(`query param value: "${v}"`)),
// simulate data load
switchMap(v => of(v).pipe(
delay(500),
map(v => ({ items: [] }))
)),
catchError(e => of({ items: [], error: e }))
);
}
You may use Map.entrySet()
method:
for (Map.Entry entry : objectSet.entrySet())
{
System.out.println("key: " + entry.getKey() + "; value: " + entry.getValue());
}
subprocess.Popen
takes a cwd
argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'
), or use r'd:\test\local'
so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t
part will be translated to a tab.
So, your new line should look like:
subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')
To use your Python script path as cwd, import os
and define cwd using this:
os.path.dirname(os.path.realpath(__file__))
For me I only have read access to run querys so I need to use this function often here is what I use:
SELECT *
FROM INFORMATION_SCHEMA.TABLES
where TABLES.TABLE_NAME like '%your table name here%'
You can replace .TABLES with .COLUMNS then it would look like this:
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE columns.COLUMN_NAME like '%your column name here%'
If you want to open your phone without touching it here is the way
Steps
adb devices
to cheek if your phone is ready or notList of devices attached
059c97f4 device
then enter the following command
adb shell input keyevent 26 && adb shell input swipe 600 600 0 0 && adb shell input text <pass> && adb shell input keyevent 66
put your password in <pass>
and done. You phone is hopefully opened
Java's Runtime object can report the JVM's memory usage. For CPU consumption you'll have to use an external utility, like Unix's top or Windows Process Manager.
By strange it can seem it works perfectly fine: date_create( '2016-02-01 + 1 day' );
echo date_create( $your_date . ' + 1 day' )->format( 'Y-m-d' );
Should do it
After a some research i found the way to bypass ssl error Trust anchor for certification path not found. This might be not a good way to do but you can use it for a testing purpose.
private HttpsURLConnection httpsUrlConnection( URL urlDownload) throws Exception {
HttpsURLConnection connection=null;
TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
@SuppressLint("TrustAllX509TrustManager")
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
@SuppressLint("TrustAllX509TrustManager")
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
}
};
SSLContext sc = SSLContext.getInstance("SSL"); // Add in try catch block if you get error.
sc.init(null, trustAllCerts, new java.security.SecureRandom()); // Add in try catch block if you get error.
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HostnameVerifier usnoHostnameVerifier = new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
SSLSocketFactory sslSocketFactory = sc.getSocketFactory();
connection = (HttpsURLConnection) urlDownload.openConnection();
connection.setHostnameVerifier(usnoHostnameVerifier);
connection.setSSLSocketFactory(sslSocketFactory);
return connection;
}
You should use textView.setGravity(Gravity.CENTER_HORIZONTAL);
.
Remember that using
LinearLayout.LayoutParams layoutParams =new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
layoutParams2.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;
won't work. This will set the gravity for the widget and not for it's text.
I have found this way of reading strings from files to work best for me
String st, full;
full="";
BufferedReader br = new BufferedReader(new FileReader(URL));
while ((st=br.readLine())!=null) {
full+=st;
}
"full" will be the completed combination of all of the lines. If you want to add a line break between the lines of text you would do
full+=st+"\n";
if you have JSON file you can set it on assets folder then call it using this code
InputStream in = mResources.getAssets().open("fragrances.json");
// where mResources object from Resources class
just in case someone finds this searching for errors concerning ActiveStorage:
if you have a controller-action where you want to generate upload-urls etc with the local disc-service (most likely in test environment), you need to include ActiveStorage::SetCurrent
in the controller in order to allow blob.service_url_for_direct_upload
to work correctly.
The answer posted to this question as an example taken from Microsoft's MSDN is nice however it doesn't directly demonstrate where the error comes from if it doesn't come from the TRY Block. I prefer this example with a very minor update to the RAISERROR Message within the CATCH Block stating that the error is from the CATCH Block. I demonstrate this in the gif as well.
BEGIN TRY
/* RAISERROR with severity 11-19 will cause execution
| to jump to the CATCH block.
*/
RAISERROR ('Error raised in TRY block.', -- Message text.
5, -- Severity. /* Severity Levels Less Than 11 do not jump to the CATCH block */
1 -- State.
);
END TRY
BEGIN CATCH
DECLARE @ErrorMessage NVARCHAR(4000);
DECLARE @ErrorSeverity INT;
DECLARE @ErrorState INT;
SELECT
@ErrorMessage = ERROR_MESSAGE(),
@ErrorSeverity = ERROR_SEVERITY(),
@ErrorState = ERROR_STATE();
/* Use RAISERROR inside the CATCH block to return error
| information about the original error that caused
| execution to jump to the CATCH block
*/
RAISERROR ('Caught Error in Catch', --@ErrorMessage, /* Message text */
@ErrorSeverity, /* Severity */
@ErrorState /* State */
);
END CATCH;
ok just to answer the original question:
you can get the padding as a usable integer like this:
var padding = parseInt($("myId").css("padding-top").replace("ems",""));
If you have defined another measurement like px just replace "ems" with "px". parseInt interprets the stringpart as a wrong value so its important to replace it with ... nothing.
I solve this problem with this code in NugetPackageConsole.and it works.The problem was in the version. i thikn it will help others.
Simple Solution to compare the two arrays:
var array1 = [2, 4];
var array2 = [4, 2];
array1.sort();
array2.sort();
if (array1[0] == array2[0]) {
console.log("Success");
}else{
console.log("Wrong");
}
DataSource is vendor-specific, for MySql you could use MysqlDataSource which is provided in the MySql Java connector jar:
MysqlDataSource dataSource = new MysqlDataSource();
dataSource.setDatabaseName("xyz");
dataSource.setUser("xyz");
dataSource.setPassword("xyz");
dataSource.setServerName("xyz.yourdomain.com");
Invalid login/password could be also related to issues in your DNS server - that's what happened to me and cost me good 5 hours of my life. See if you can specify ip address instead on domain name.
Note as of Symfony 3.3 EntityManager is depreciated. Use EntityManagerInterface instead.
namespace AppBundle\Service;
use Doctrine\ORM\EntityManagerInterface;
class Someclass {
protected $em;
public function __construct(EntityManagerInterface $entityManager)
{
$this->em = $entityManager;
}
public function somefunction() {
$em = $this->em;
...
}
}
I'm not sure if that is possible. The MSDN GetFiles reference says a search pattern, not a list of search patterns.
I might be inclined to fetch each list separately and "foreach" them into a final list.
public init() {_x000D_
return from(_x000D_
fetch("assets/server-config.json").then(response => {_x000D_
return response.json();_x000D_
})_x000D_
)_x000D_
.pipe(_x000D_
map(config => {_x000D_
return config;_x000D_
})_x000D_
)_x000D_
.toPromise();_x000D_
}
_x000D_
Adding [AllowHtml]
on the specific property is the recommended solution as there are plenty of blogs and comments suggesting to decrease the security level, which should be unacceptable.
By adding that, the MVC framework will allow the Controller to be hit and the code in that controller to be executed.
However, it depends on your code, filters, etc. how the response is generated and whether there is any further validation that might trigger another similar error.
In any case, adding [AllowHtml]
attribute is the right answer, as it allows html to be deserialized in the controller. Example in your viewmodel:
[AllowHtml]
public string MessageWithHtml {get; set;}
ngKeypress
, ngKeydown
and ngKeyup
are now part of AngularJS.
<!-- you can, for example, specify an expression to evaluate -->
<input ng-keypress="count = count + 1" ng-init="count=0">
<!-- or call a controller/directive method and pass $event as parameter.
With access to $event you can now do stuff like
finding which key was pressed -->
<input ng-keypress="changed($event)">
Read more here:
https://docs.angularjs.org/api/ng/directive/ngKeypress https://docs.angularjs.org/api/ng/directive/ngKeydown https://docs.angularjs.org/api/ng/directive/ngKeyup
Earlier solutions:
Solution 1: Use ng-change
with ng-model
<input type="text" placeholder="+639178983214" ng-model="mobileNumber"
ng-controller="RegisterDataController" ng-change="keydown()">
JS:
function RegisterDataController($scope) {
$scope.keydown = function() {
/* validate $scope.mobileNumber here*/
};
}
Solution 2. Use $watch
<input type="text" placeholder="+639178983214" ng-model="mobileNumber"
ng-controller="RegisterDataController">
JS:
$scope.$watch("mobileNumber", function(newValue, oldValue) {
/* change noticed */
});
Laravel provides bunch of helper functions and for your requirement you can simply
use url() function of Laravel Helpers
but in case of Laravel 5.2 you will have to use url('/')
here is the list of all other helper functions of Laravel
Standard input - this is the file handle that your process reads to get information from you.
Standard output - your process writes conventional output to this file handle.
Standard error - your process writes diagnostic output to this file handle.
That's about as dumbed-down as I can make it :-)
Of course, that's mostly by convention. There's nothing stopping you from writing your diagnostic information to standard output if you wish. You can even close the three file handles totally and open your own files for I/O.
When your process starts, it should already have these handles open and it can just read from and/or write to them.
By default, they're probably connected to your terminal device (e.g., /dev/tty
) but shells will allow you to set up connections between these handles and specific files and/or devices (or even pipelines to other processes) before your process starts (some of the manipulations possible are rather clever).
An example being:
my_prog <inputfile 2>errorfile | grep XYZ
which will:
my_prog
.inputfile
as your standard input (file handle 0).errorfile
as your standard error (file handle 2).grep
.my_prog
to the standard input of grep
.Re your comment:
When I open these files in /dev folder, how come I never get to see the output of a process running?
It's because they're not normal files. While UNIX presents everything as a file in a file system somewhere, that doesn't make it so at the lowest levels. Most files in the /dev
hierarchy are either character or block devices, effectively a device driver. They don't have a size but they do have a major and minor device number.
When you open them, you're connected to the device driver rather than a physical file, and the device driver is smart enough to know that separate processes should be handled separately.
The same is true for the Linux /proc
filesystem. Those aren't real files, just tightly controlled gateways to kernel information.
<?php echo substr($string, 0, strlen($string) - 3); ?>
The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants (except when using prepared statements).
With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1):
SELECT * FROM tbl LIMIT 5,10; # Retrieve rows 6-15
To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
With one argument, the value specifies the number of rows to return from the beginning of the result set:
SELECT * FROM tbl LIMIT 5; # Retrieve first 5 rows
In other words, LIMIT row_count is equivalent to LIMIT 0, row_count.
All details on: http://dev.mysql.com/doc/refman/5.0/en/select.html
Non-standard function, but its implemented on most common compilers:
int input = MY_VALUE;
char buffer[100] = {0};
int number_base = 10;
std::string output = itoa(input, buffer, number_base);
Update
C++11 introduced several std::to_string
overloads (note that it defaults to base-10).
Similar to the previous answer: Just use the 'name' key with your regular add_index line:
def change
add_index :studies, :user_id, name: 'my_index'
end

Debug.Print ArrayLen(arr) ' Prints 3. Everything's going to be ok.
The JSON.stringify
method supported by many modern browsers (including IE8) can output a beautified JSON string:
JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4); // stringify with 4 spaces at each level
Demo: http://jsfiddle.net/AndyE/HZPVL/
This method is also included with json2.js, for supporting older browsers.
If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.
If your modulus / divisor is a known constant, and you care about performance, see this and this. A multiplicative inverse is even possible for loop-invariant values that aren't known until runtime, e.g. see https://libdivide.com/ (But without JIT code-gen, that's less efficient than hard-coding just the steps necessary for one constant.)
Never use div
for known powers of 2: it's much slower than and
for remainder, or right-shift for divide. Look at C compiler output for examples of unsigned or signed division by powers of 2, e.g. on the Godbolt compiler explorer. If you know a runtime input is a power of 2, use lea eax, [esi-1]
; and eax, edi
or something like that to do x & (y-1)
. Modulo 256 is even more efficient: movzx eax, cl
has zero latency on recent Intel CPUs (mov-elimination), as long as the two registers are separate.
The DIV
instruction (and its counterpart IDIV
for signed numbers) gives both the quotient and remainder. For unsigned, remainder and modulus are the same thing. For signed idiv
, it gives you the remainder (not modulus) which can be negative:
e.g. -5 / 2 = -2 rem -1
. x86 division semantics exactly match C99's %
operator.
DIV r32
divides a 64-bit number in EDX:EAX
by a 32-bit operand (in any register or memory) and stores the quotient in EAX
and the remainder in EDX
. It faults on overflow of the quotient.
Unsigned 32-bit example (works in any mode)
mov eax, 1234 ; dividend low half
mov edx, 0 ; dividend high half = 0. prefer xor edx,edx
mov ebx, 10 ; divisor can be any register or memory
div ebx ; Divides 1234 by 10.
; EDX = 4 = 1234 % 10 remainder
; EAX = 123 = 1234 / 10 quotient
In 16-bit assembly you can do div bx
to divide a 32-bit operand in DX:AX
by BX
. See Intel's Architectures Software Developer’s Manuals for more information.
Normally always use xor edx,edx
before unsigned div
to zero-extend EAX into EDX:EAX. This is how you do "normal" 32-bit / 32-bit => 32-bit division.
For signed division, use cdq
before idiv
to sign-extend EAX into EDX:EAX. See also Why should EDX be 0 before using the DIV instruction?. For other operand-sizes, use cbw
(AL->AX), cwd
(AX->DX:AX), cdq
(EAX->EDX:EAX), or cqo
(RAX->RDX:RAX) to set the top half to 0
or -1
according to the sign bit of the low half.
div
/ idiv
are available in operand-sizes of 8, 16, 32, and (in 64-bit mode) 64-bit. 64-bit operand-size is much slower than 32-bit or smaller on current Intel CPUs, but AMD CPUs only care about the actual magnitude of the numbers, regardless of operand-size.
Note that 8-bit operand-size is special: the implicit inputs/outputs are in AH:AL (aka AX), not DL:AL. See 8086 assembly on DOSBox: Bug with idiv instruction? for an example.
Signed 64-bit division example (requires 64-bit mode)
mov rax, 0x8000000000000000 ; INT64_MIN = -9223372036854775808
mov ecx, 10 ; implicit zero-extension is fine for positive numbers

div dword 10
is not encodeable into machine code (so your assembler will report an error about invalid operands).
Unlike with mul
/imul
(where you should normally use faster 2-operand imul r32, r/m32
or 3-operand imul r32, r/m32, imm8/32
instead that don't waste time writing a high-half result), there is no newer opcode for division by an immediate, or 32-bit/32-bit => 32-bit division or remainder without the high-half dividend input.
Division is so slow and (hopefully) rare that they didn't bother to add a way to let you avoid EAX and EDX, or to use an immediate directly.
div and idiv will fault if the quotient doesn't fit into one register (AL / AX / EAX / RAX, the same width as the dividend). This includes division by zero, but will also happen with a non-zero EDX and a smaller divisor. This is why C compilers just zero-extend or sign-extend instead of splitting up a 32-bit value into DX:AX.
And also why INT_MIN / -1
is C undefined behaviour: it overflows the signed quotient on 2's complement systems like x86. See Why does integer division by -1 (negative one) result in FPE? for an example of x86 vs. ARM. x86 idiv
does indeed fault in this case.
The x86 exception is #DE
- divide exception. On Unix/Linux systems, the kernel delivers a SIGFPE arithmetic exception signal to processes that cause a #DE exception. (On which platforms does integer divide by zero trigger a floating point exception?)
For div
, using a dividend with high_half < divisor
is safe. e.g. 0x11:23 / 0x12
is less than 0xff
so it fits in an 8-bit quotient.
Extended-precision division of a huge number by a small number can be implemented by using the remainder from one chunk as the high-half dividend (EDX) for the next chunk. This is probably why they chose remainder=EDX quotient=EAX instead of the other way around.
It's a new feature called Modules or "semantic import". There's more info in the WWDC 2013 videos for Session 205 and 404. It's kind of a better implementation of the pre-compiled headers. You can use modules with any of the system frameworks in iOS 7 and Mavericks. Modules are a packaging together of the framework executable and its headers and are touted as being safer and more efficient than #import
.
One of the big advantages of using @import
is that you don't need to add the framework in the project settings, it's done automatically. That means that you can skip the step where you click the plus button and search for the framework (golden toolbox), then move it to the "Frameworks" group. It will save many developers from the cryptic "Linker error" messages.
You don't actually need to use the @import
keyword. If you opt-in to using modules, all #import
and #include
directives are mapped to use @import
automatically. That means that you don't have to change your source code (or the source code of libraries that you download from elsewhere). Supposedly using modules improves the build performance too, especially if you haven't been using PCHs well or if your project has many small source files.
Modules are pre-built for most Apple frameworks (UIKit, MapKit, GameKit, etc). You can use them with frameworks you create yourself: they are created automatically if you create a Swift framework in Xcode, and you can manually create a ".modulemap" file yourself for any Apple or 3rd-party library.
You can use code-completion to see the list of available frameworks:
Modules are enabled by default in new projects in Xcode 5. To enable them in an older project, go into your project build settings, search for "Modules" and set "Enable Modules" to "YES". The "Link Frameworks" should be "YES" too:
You have to be using Xcode 5 and the iOS 7 or Mavericks SDK, but you can still release for older OSs (say iOS 4.3 or whatever). Modules don't change how your code is built or any of the source code.
From the WWDC slides:
- Imports complete semantic description of a framework
- Doesn't need to parse the headers
- Better way to import a framework’s interface
- Loads binary representation
- More flexible than precompiled headers
- Immune to effects of local macro definitions (e.g.
#define readonly 0x01
)- Enabled for new projects by default
To explicitly use modules:
Replace #import <Cocoa/Cocoa.h>
with @import Cocoa;
You can also import just one header with this notation:
@import iAd.ADBannerView;
The submodules autocomplete for you in Xcode.

I just met the same issue and see this post. For me it's because I forgot the set the identifier of cell, also as mentioned in other answers. What I want to say is that if you are using the storyboard to load custom cell we don't need to register the table view cell in code, which can cause other problems.
See this post for detail:
Use the following notations:
Thanks @lit for your ideal answer in below comment:
Use the environment variables %ProgramFiles% and %ProgramFiles(x86)%

Session.Abandon()
http://msdn.microsoft.com/en-us/library/ms524310.aspx
Here is a little more detail on the HttpSessionState
object:
http://msdn.microsoft.com/en-us/library/system.web.sessionstate.httpsessionstate_members.aspx
I have also used a non-generic version, using the new
keyword:
public interface IMetadata
{
Type DataType { get; }
object Data { get; }
}
public interface IMetadata<TData> : IMetadata
{
new TData Data { get; }
}
Explicit interface implementation is used to allow both Data
members:
public class Metadata<TData> : IMetadata<TData>
{
public Metadata(TData data)
{
Data = data;
}
public Type DataType
{
get { return typeof(TData); }
}
object IMetadata.Data
{
get { return Data; }
}
public TData Data { get; private set; }
}
You could derive a version targeting value types:
public interface IValueTypeMetadata : IMetadata
{
}
public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{
}
public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
public ValueTypeMetadata(TData data) : base(data)
{}
}
This can be extended to any kind of generic constraints.
Use the following,
echo "<script type='text/javascript'> window.location.href = '$file_name'; </script>";
I would simply use,
np.asarray(input, dtype=np.float)[0]
input
is an ndarray
of the right dtype, there is no overhead, since np.asarray
does nothing in this case.input
is a list
, np.asarray
makes sure the output is of the right type.Problem is caused by comma at the end of (in your case each) JSON object placed in the array:
{
"number": "...",
"title": ".." , //<- see that comma?
}
If you remove them your data will become
[
{
"number": "3",
"title": "hello_world"
}, {
"number": "2",
"title": "hello_world"
}
]
and
Wrapper[] data = gson.fromJson(jElement, Wrapper[].class);
should work fine.
In case you are looking for datepicker in spanish (datepicker en español)

Here is how I do it in Angular 7.3
// you can put this method in a module and reuse it as needed
resetForm(form: FormGroup) {
form.reset();
Object.keys(form.controls).forEach(key => {
form.get(key).setErrors(null) ;
});
}
There was no need to call form.clearValidators()

Make resource controller with Model.
php artisan make:controller PostController --model=Post
Yes, you can access it through GET
and POST
(trying this simple task would have made you aware of that).
Yes, there are other ways, one of the other "preferred" ways is using sessions. When you would want to use hidden over session is kind of touchy, but any GET / POST data is easily manipulated by the end user. A session is a bit more secure given it is saved to a file on the server and it is much harder for the end user to manipulate without access through the program.
No use script tag only.
Solution with |
:
script
| if (10 == 10) {
| alert("working")
| }
Or with a .
:
script.
if (10 == 10) {
alert("working")
}

As I understand, you want the average value for each id at each pass. The solution is
SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;
try this code
you can not store mapper in NSUserDefault, you can only store NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.
let myData = NSKeyedArchiver.archivedData(withRootObject: myJson)

You can't easily do this in a generic way: you can only convert an integer to a specific type of enum. As Nicholas has shown, this is a trivial cast if you only care about one kind of enum, but if you want to write a generic method that can handle different kinds of enums, things get a bit more complicated. You want a method along the lines of:
public static string GetEnumDescription<TEnum>(int value)
{
return GetEnumDescription((Enum)((TEnum)value)); // error!
}
but this results in a compiler error that "int can't be converted to TEnum" (and if you work around this, that "TEnum can't be converted to Enum"). So you need to fool the compiler by inserting casts to object:
public static string GetEnumDescription<TEnum>(int value)
{
return GetEnumDescription((Enum)(object)((TEnum)(object)value)); // ugly, but works
}
You can now call this to get a description for whatever type of enum is at hand:
GetEnumDescription<MyEnum>(1);
GetEnumDescription<YourEnum>(2);
Here is my functional version of recursive flatten which handles both tuples and lists, and lets you throw in any mix of positional arguments. Returns a generator which produces the entire sequence in order, arg by arg:
flatten = lambda *n: (e for a in n
for e in (flatten(*a) if isinstance(a, (tuple, list)) else (a,)))
Usage:
l1 = ['a', ['b', ('c', 'd')]]
l2 = [0, 1, (2, 3), [[4, 5, (6, 7, (8,), [9]), 10]], (11,)]
print list(flatten(l1, -2, -1, l2))
['a', 'b', 'c', 'd', -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
It's actually very easy to handle using Scala f
interpolator - https://docs.scala-lang.org/overviews/core/string-interpolation.html
Suppose we want to round till 2 decimal places:
scala> val sum = 1 + 1/4D + 1/7D + 1/10D + 1/13D
sum: Double = 1.5697802197802198
scala> println(f"$sum%1.2f")
1.57
Based on another question on stackoverflow, I got this code.. This calculates the result in meters, not in miles :)
public static float distFrom(float lat1, float lng1, float lat2, float lng2) {
double earthRadius = 6371000; //meters
double dLat = Math.toRadians(lat2-lat1);
double dLng = Math.toRadians(lng2-lng1);
double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
Math.sin(dLng/2) * Math.sin(dLng/2);
double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
float dist = (float) (earthRadius * c);
return dist;
}
