I tried using phyatt's AspectRatioPixmapLabel
class, but experienced a few problems:
QLabel::setPixmap(...)
inside the resizeEvent method, because QLabel
actually calls updateGeometry
inside setPixmap
, which may trigger resize events...heightForWidth
seemed to be ignored by the containing widget (a QScrollArea
in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
QLabel
's implementation of minimumSizeHint()
does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite itThat said, here is my solution. I found that I could just use setScaledContents(true)
and let QLabel
handle the resizing.
Of course, this depends on the containing widget / layout honoring the heightForWidth
.
aspectratiopixmaplabel.h
#ifndef ASPECTRATIOPIXMAPLABEL_H
#define ASPECTRATIOPIXMAPLABEL_H
#include <QLabel>
#include <QPixmap>
class AspectRatioPixmapLabel : public QLabel
{
Q_OBJECT
public:
explicit AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent = 0);
virtual int heightForWidth(int width) const;
virtual bool hasHeightForWidth() { return true; }
virtual QSize sizeHint() const { return pixmap()->size(); }
virtual QSize minimumSizeHint() const { return QSize(0, 0); }
};
#endif // ASPECTRATIOPIXMAPLABEL_H
aspectratiopixmaplabel.cpp
#include "aspectratiopixmaplabel.h"
AspectRatioPixmapLabel::AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent) :
QLabel(parent)
{
QLabel::setPixmap(pixmap);
setScaledContents(true);
QSizePolicy policy(QSizePolicy::Maximum, QSizePolicy::Maximum);
policy.setHeightForWidth(true);
this->setSizePolicy(policy);
}
int AspectRatioPixmapLabel::heightForWidth(int width) const
{
if (width > pixmap()->width()) {
return pixmap()->height();
} else {
return ((qreal)pixmap()->height()*width)/pixmap()->width();
}
}
This is what I use to control headers/caching, I'm not an Apache pro, so let me know if there is room for improvement, but I know that this has been working well on all of my sites for some time now.
http://httpd.apache.org/docs/2.2/mod/mod_expires.html
This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.
These HTTP headers are an instruction to the client about the document's validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered "expired" and invalid, and a new copy must be obtained from the source.
# BEGIN Expires

I don't know much about the MySQL command line interface, but assuming you only need help with the bashing, you should try to either swap the commands around like so:
myvariable=$(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p$password)
which echos the string into MySQL. Or, you can be more fancy and use some new bash-features (the here string)
myvariable=$(mysql database -u $user -p$password<<<"SELECT A, B, C FROM table_a")
resulting in the same thing (assuming you're using a recent enough bash version), without involving echo.
Please note that the -p$password is not a typo, but is the way MySQL expects passwords to be entered through the command line (with no space between the option and value).
Note that myvariable will contain everything that MySQL outputs on standard out (usually everything but error messages), including any and all column headers, ASCII-art frames and so on, which may or may not be what you want.
EDIT:
As has been noted, there appears to be a -e
parameter to MySQL, I'd go for that one, definitely.
Unless it is the most trivial case, there is only one sane way to use command line options in Ruby. It is called docopt and documented here.
What is amazing with it, is it's simplicity. All you have to do, is specify the "help" text for your command. What you write there will then be auto-parsed by the standalone (!) ruby library.
From the example:
#!/usr/bin/env ruby
require 'docopt.rb'
doc = <<DOCOPT
Usage: #{__FILE__} --help
#{__FILE__} -v...
#{__FILE__} go [go]
#{__FILE__} (--path=<path>)...
#{__FILE__} <file> <file>
Try: #{__FILE__} -vvvvvvvvvv
#{__FILE__} go go
#{__FILE__} --path ./here --path ./there
#{__FILE__} this.txt that.txt
DOCOPT
begin
require "pp"
pp Docopt::docopt(doc)
rescue Docopt::Exit => e
puts e.message
end
The output:
$ ./counted_example.rb -h
Usage: ./counted_example.rb --help
./counted_example.rb -v...
./counted_example.rb go [go]
./counted_example.rb (--path=<path>)...
./counted_example.rb <file> <file>
Try: ./counted_example.rb -vvvvvvvvvv
./counted_example.rb go go
./counted_example.rb --path ./here --path ./there
./counted_example.rb this.txt that.txt
$ ./counted_example.rb something else
{"--help"=>false,
"-v"=>0,
"go"=>0,
"--path"=>[],
"<file>"=>["something", "else"]}
$ ./counted_example.rb -v
{"--help"=>false, "-v"=>1, "go"=>0, "--path"=>[], "<file>"=>[]}
$ ./counted_example.rb go go
{"--help"=>false, "-v"=>0, "go"=>2, "--path"=>[], "<file>"=>[]}
Enjoy!
Note that %in%
returns a logical vector of TRUE
and FALSE
. To negate it, you can use !
in front of the logical statement:
SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean,
!where_case_travelled_1 %in%
c('Outside Canada','Outside province/territory of residence but within Canada'))
Regarding your original approach with -c(...)
, -
is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")
). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -
.
Use typeof
:
> typeof "foo"
"string"
> typeof true
"boolean"
> typeof 42
"number"
So you can do:
if(typeof bar === 'number') {
//whatever
}
Be careful though if you define these primitives with their object wrappers (which you should never do, use literals where ever possible):
> typeof new Boolean(false)
"object"
> typeof new String("foo")
"object"
> typeof new Number(42)
"object"
The type of an array is still object
. Here you really need the instanceof
operator.
Update:
Another interesting way is to examine the output of Object.prototype.toString
:
> Object.prototype.toString.call([1,2,3])
"[object Array]"
> Object.prototype.toString.call("foo bar")
"[object String]"
> Object.prototype.toString.call(45)
"[object Number]"
> Object.prototype.toString.call(false)
"[object Boolean]"
> Object.prototype.toString.call(new String("foo bar"))
"[object String]"
> Object.prototype.toString.call(null)
"[object Null]"
> Object.prototype.toString.call(/123/)
"[object RegExp]"
> Object.prototype.toString.call(undefined)
"[object Undefined]"
With that you would not have to distinguish between primitive values and objects.
select * from [schema_name].sys.tables
This should work. Make sure you are on the server which consists of your "[schema_name]"
Fragment transactions should not be executed after Activity.onStop()
!
Check that you do not have any callbacks that could execute transaction after onStop()
. It is better to fix the reason instead of trying to walk around the problem with approaches like .commitAllowingStateLoss()
The onkeyup event does "work" as you intend:

There is far more efficient answer: just put the following instructions in the Form_Load
:
Me.MinimumSize = New Size(Width, Height)
Me.MaximumSize = Me.MinimumSize
It looks like your longs are seconds, and not milliseconds. Date constructor takes time as millis, so
Date d = new Date(timeInSeconds * 1000);
The accepted answer works pretty good. I wanted more control so I added a couple of functions more to the script:
function unmuteVideo() {
player.unMute();
return false;
}
function muteVideo() {
player.mute();
return false;
}
function setVolumeVideo(volume) {
player.setVolume(volume);
return false;
}
And here is the HTML:
<br>
<button type="button" onclick="unmuteVideo();">Unmute Video</button>
<button type="button" onclick="muteVideo();">Mute Video</button>
<br>
<br>
<button type="button" onclick="setVolumeVideo(100);">Volume 100%</button>
<button type="button" onclick="setVolumeVideo(75);">Volume 75%</button>
<button type="button" onclick="setVolumeVideo(50);">Volume 50%</button>
<button type="button" onclick="setVolumeVideo(25);">Volume 25%</button>

The answer is: you can't only through sms, i have tried that approach before.
You could fetch the base station IDs, but this won't help you a lot without the location of the base station itself and this informations are really hard to retrieve from the providers.
I have looked through the 3 apps you have listed in your question:
As also noted in the docs here.
Go to Python X.X/Lib
and add these lines to the site.py
there,
import sys
sys.path.append("yourpathstring")
This changes your sys.path
so that on every load, it will have that value in it..
As stated here about site.py
,
This module is automatically imported during initialization. Importing this module will append site-specific paths to the module search path and add a few builtins.
For other possible methods of adding some path to sys.path
see these docs
Try this code, I get working fine.
webSettings.setSupportZoom(true);
webSettings.setBuiltInZoomControls(true);
webSettings.setDisplayZoomControls(false);
A useful feature for this is using static
As others have said, you have to create a class for your globals:
public static class Globals {
public const float PI = 3.14;
}
But you can import it like this in order to no longer write the class name in front of its static properties:
using static Globals;
[...]
Console.WriteLine("Pi is " + PI);
dispatchTouchEvent handles before onInterceptTouchEvent.
Using this simple example:
main = new LinearLayout(this){
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
System.out.println("Event - onInterceptTouchEvent");
return super.onInterceptTouchEvent(ev);
//return false; //event get propagated
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
System.out.println("Event - dispatchTouchEvent");
return super.dispatchTouchEvent(ev);
//return false; //event DONT get propagated
}
};
main.setBackgroundColor(Color.GRAY);
main.setLayoutParams(new LinearLayout.LayoutParams(320,480));
viewA = new EditText(this);
viewA.setBackgroundColor(Color.YELLOW);
viewA.setTextColor(Color.BLACK);
viewA.setTextSize(16);
viewA.setLayoutParams(new LinearLayout.LayoutParams(320,80));
main.addView(viewA);
setContentView(main);
You can see that the log willl be like:
I/System.out(25900): Event - dispatchTouchEvent
I/System.out(25900): Event - onInterceptTouchEvent
So in case you are working with these 2 handlers use dispatchTouchEvent to handle on first instance the event, which will go to onInterceptTouchEvent.
Another difference is that if dispatchTouchEvent return 'false' the event dont get propagated to the child, in this case the EditText, whereas if you return false in onInterceptTouchEvent the event still get dispatch to the EditText
Try this:
if(Math.floor(id) == id && $.isNumeric(id))
alert('yes its an int!');
$.isNumeric(id)
checks whether it's numeric or not
Math.floor(id) == id
will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.

First of all, a warning: what follows is strictly in the realm of ugly, undocumented hacks. Do not rely on this working - even if it works for you now, it may stop working tomorrow, with any minor or major .NET update.
You can use the information in this article on CLR internals MSDN Magazine Issue 2005 May - Drill Into .NET Framework Internals to See How the CLR Creates Runtime Objects - last I checked, it was still applicable. Here's how this is done (it retrieves the internal "Basic Instance Size" field via TypeHandle
of the type).
object obj = new List<int>(); // whatever you want to get the size of
RuntimeTypeHandle th = obj.GetType().TypeHandle;
int size = *(*(int**)&th + 1);
Console.WriteLine(size);
This works on 3.5 SP1 32-bit. I'm not sure if field sizes are the same on 64-bit - you might have to adjust the types and/or offsets if they are not.
This will work for all "normal" types, for which all instances have the same, well-defined types. Those for which this isn't true are arrays and strings for sure, and I believe also StringBuilder
. For them you'll have add the size of all contained elements to their base instance size.
If you really want to use linq, you can do something like this
li= (from tl in li
select new Myclass
{
name = tl.name,
age = (tl.name == "di" ? 10 : (tl.name == "marks" ? 20 : 30))
}).ToList();
or
li = li.Select(ex => new MyClass { name = ex.name, age = (ex.name == "di" ? 10 : (ex.name == "marks" ? 20 : 30)) }).ToList();
This assumes that there are only 3 types of name
. I would externalize that part into a function to make it more manageable.
with JQuery .toggle()
you can accomplish it easily
$( ".target" ).toggle();
first, you need to load URL helper like this type or you can upload within autoload.php file:
$this->load->helper('url');
if (!$user_logged_in)
{
redirect('/account/login', 'refresh');
}
From your question, I think what you are trying to do is to store something (an object, a string...) to foward it then to another servlet, using RequestDispatcher(). To do this you don't need to set a paramater but an attribute using
void setAttribute(String name, Object o);
and then
Object getAttribute(String name);

For those interested on detail on why maven argline tag should be preferred to the systemProperties one, look, for example:
You can use .is(':visible')
Selects all elements that are visible.
For example:
if($('#selectDiv').is(':visible')){
Also, you can get the div which is visible by:
$('div:visible').callYourFunction();
Live example:
console.log($('#selectDiv').is(':visible'));_x000D_

This Might be help some:

The onload property of the GlobalEventHandlers mixin is an event handler for the load event of a Window, XMLHttpRequest, element, etc., which fires when the resource has loaded.
So basically javascript already has onload method on window which get executed which page fully loaded including images...
You can do something:
var spinner = true;
window.onload = function() {
//whatever you like to do now, for example hide the spinner in this case
spinner = false;
};
Thinking a little bit outside the box here I'm going to propose that powershell may be an answer on up-to-date XP/2003 machines and certainly on Vista/2008 and newer (instead of .bat/.cmd). Anyone who has some Perl in their background should feel at-home pretty quickly.
$serviceName = "ServiceName";
$serviceStatus = (get-service "$serviceName").Status;
if ($serviceStatus -eq "Running") {
echo "Service is Running";
}
else {
#Could be Stopped, Stopping, Paused, or even Starting...
echo "Service is $serviceStatus";
}
Another way, if you have significant investment in batch is to run the PS script as a one-liner, returning an exit code.
@ECHO off
SET PS=powershell -nologo -command
%PS% "& {if((get-service SvcName).Status -eq 'Running'){exit 1}}"
ECHO.%ERRORLEVEL%
Running as a one-liner also gets around the default PS code signing policy at the expense of messiness. To put the PS commands in a .ps1 file and run like powershell myCode.ps1
you may find signing your powershell scripts is neccessary to run them in an automated way (depends on your environment). See http://www.hanselman.com/blog/SigningPowerShellScripts.aspx for details
You can also use fcntl to change the file flags in-fly.
fl = fcntl.fcntl(fd.fileno(), fcntl.F_GETFL)
fl |= os.O_SYNC # or os.O_DSYNC (if you don't care the file timestamp updates)
fcntl.fcntl(fd.fileno(), fcntl.F_SETFL, fl)
I believe that using "cbind" is the simplest way to add a column to a data frame in R. Below an example:
myDf = data.frame(index=seq(1,10,1), Val=seq(1,10,1))
newCol= seq(2,20,2)
myDf = cbind(myDf,newCol)
My preferred method for reloading the same page is $_SERVER['PHP_SELF']
header('Location: '.$_SERVER['PHP_SELF']);
die;
Don't forget to die or exit after your header();
Edit: (Thanks @RafaelBarros )
If the query string is also necessary, use
header('Location:'.$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING']);
die;
Edit: (thanks @HugoDelsing)
When htaccess url manipulation is in play the value of $_SERVER['PHP_SELF'] may take you to the wrong place. In that case the correct url data will be in $_SERVER['REQUEST_URI']
for your redirect, which can look like Nabil's answer below:
header("Location: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
exit;
You can also use $_SERVER[REQUEST_URI] to assign the correct value to $_SERVER['PHP_SELF']
if desired. This can help if you use a redirect function heavily and you don't want to change it. Just set the correct vale in your request handler like this:
$_SERVER['PHP_SELF'] = 'https://sample.com/controller/etc';
$(window).on("touchstart", function(ev) {
var e = ev.originalEvent;
console.log(e.touches);
});
I know it been asked a long time ago, but I thought a concrete example might help.
I'm not sure whether you think about:
select * from friend f
where not exists (
select 1 from likes l where f.id1 = l.id and f.id2 = l.id2
)
it works only if id1 is related with id1 and id2 with id2 not both.
Try this
INSERT INTO dbo.DB1.TempTable
(COLUMNS)
SELECT COLUMNS_IN_SAME_ORDER FROM dbo.DB2.TempTable
This will only fail if an item in dbo.DB2.TempTable is in already in dbo.DB1.TempTable.
I always try to factor out complex boolean expressions into meaningful variables (you could probably think of better names based on what these columns are used for):
bool notColumnsABC = (columnname != a && columnname != b && columnname != c);
bool notColumnA2OrBoxIsChecked = ( columnname != A2 || checkbox.checked );
if ( notColumnsABC
&& notColumnA2OrBoxIsChecked )
{
"statement 1"
}
The safest place to get the correct width and height without the scrollbars is from the HTML element. Try this:
var width = document.documentElement.clientWidth
var height = document.documentElement.clientHeight
Browser support is pretty decent, with IE 9 and up supporting this. For OLD IE, use one of the many fallbacks mentioned here.
You have asked two questions, one in the title about the difference between PNG8 and PNG24, which has received a few answers, namely that PNG24 has 8-bit red, green, and blue channels, and PNG-8 has a single 8-bit index into a palette. Naturally, PNG24 usually has a larger filesize than PNG8. Furthermore, PNG8 usually means that it is opaque or has only binary transparency (like GIF); it's defined that way in ImageMagick/GraphicsMagick.
This is an answer to the other one, "I would like to know that if I use either type in my html page, will there be any error? Or is this only quality matter?"
You can put either type on an HTML page and no, this won't cause an error; the files should all be named with the ".png" extension and referred to that way in your HTML. Years ago, early versions of Internet Explorer would not handle PNG with an alpha channel (PNG32) or indexed-color PNG with translucent pixels properly, so it was useful to convert such images to PNG8 (indexed-color with binary transparency conveyed via a PNG tRNS chunk) -- but still use the .png extension, to be sure they would display properly on IE. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.
The names PNG8 and PNG24 aren't mentioned in the PNG specification, which simply calls them all "PNG". Other names, invented by others, include
There are many more possible combinations including grayscale with 1, 2, 4, 8, or 16-bit samples and indexed PNG with 1, 2, or 4-bit samples (and any of those with transparent or translucent pixels), but those don't have special names.
I'd like to add that TypeGuards only work on strings or numbers, if you want to compare an object use instanceof
if(task.id instanceof UUID) {
//foo
}
Here is what I learned: PYTHONPATH is a directory to add to the Python import search path "sys.path", which is made up of current dir. CWD, PYTHONPATH, standard and shared library, and customer library. For example:
% python3 -c "import sys;print(sys.path)"
['',
'/home/username/Documents/DjangoTutorial/mySite',
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload',
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
where the first path '' denotes the current dir., the 2nd path is via
%export PYTHONPATH=/home/username/Documents/DjangoTutorial/mySite
which can be added to ~/.bashrc to make it permanent, and the rest are Python standard and dynamic shared library plus third-party library such as django.
As said not to mess with PYTHONHOME, even setting it to '' or 'None' will cause python3 shell to stop working:
% export PYTHONHOME=''
% python3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'
Current thread 0x00007f18a44ff740 (most recent call first):
Aborted (core dumped)
Note that if you start a Python script, the CWD will be the script's directory. For example:
username@bud:~/Documents/DjangoTutorial% python3 mySite/manage.py runserver
==== Printing sys.path ====
/home/username/Documents/DjangoTutorial/mySite # CWD is where manage.py resides
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages
You can also append a path to sys.path at run-time: Suppose you have a file Fibonacci.py in ~/Documents/Python directory:
username@bud:~/Documents/DjangoTutorial% python3
>>> sys.path.append("/home/username/Documents")
>>> print(sys.path)
['', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload',
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages',
'/home/username/Documents']
>>> from Python import Fibonacci as fibo
or via
% PYTHONPATH=/home/username/Documents:$PYTHONPATH
% python3
>>> print(sys.path)
['',
'/home/username/Documents', '/home/username/Documents/DjangoTutorial/mySite',
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload',
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
>>> from Python import Fibonacci as fibo
#include <bits/stdc++.h> // to include all libraries
using namespace std;
int main()
{
double a,b;
cin>>a>>b;
double x=a/b; //say we want to divide a/b
cout<<fixed<<setprecision(10)<<x; //for precision upto 10 digit
return 0;
}
input: 1987 31
output: 662.3333333333 10 digits after decimal point
Use SQL server isnull function
public string absentDayNo(DateTime sdate, DateTime edate, string idemp)
{
string result="0";
string myQuery="select isnull(COUNT(idemp_atd),0) as absentDayNo from td_atd where ";
myQuery +=" absentdate_atd between '"+sdate+"' and '"+edate+" ";
myQuery +=" and idemp_atd='"+idemp+"' group by idemp_atd ";
SqlCommand cmd = new SqlCommand(myQuery, conn);
conn.Open();
//System.NullReferenceException occurs when their is no data/result
string getValue = cmd.ExecuteScalar().ToString();
if (getValue != null)
{
result = getValue.ToString();
}
conn.Close();
return result;
}
I know this is an older post, but I spent a long time trying to find a solution. I came across a decent one using only ReportLab and PyPDF so I thought I'd share:
PdfFileReader()
, we'll call this inputPdfFileReader()
, we'll call this textPdfFileWriter()
, we'll call this output.mergePage(*text*.getPage(0))
for each page you want the text added to, then use output.addPage()
to add the modified pages to a new documentThis works well for simple text additions. See PyPDF's sample for watermarking a document.
Here is some code to answer the question below:
packet = StringIO.StringIO()
can = canvas.Canvas(packet, pagesize=letter)
<do something with canvas>
can.save()
packet.seek(0)
input = PdfFileReader(packet)
From here you can merge the pages of the input file with another document.
Tests
On the Tests
class we will add an @XmlRootElement
annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData
property differs from the default mapping we will use the @XmlElement
annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted
package forum11221136;
import javax.xml.bind.annotation.*;
@XmlRootElement
public class Tests {
TestData testData;
@XmlElement(name="test-data")
public TestData getTestData() {
return testData;
}
public void setTestData(TestData testData) {
this.testData = testData;
}
}
TestData
On this class I used the @XmlType
annotation to specify the order in which the elements should be ordered in. I added a testData
property that appeared to be missing. I also used an @XmlElement
annotation for the same reason as in the Tests
class.
package forum11221136;
import java.util.List;
import javax.xml.bind.annotation.*;
@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
String title;
String book;
String count;
List<TestData> testData;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getBook() {
return book;
}
public void setBook(String book) {
this.book = book;
}
public String getCount() {
return count;
}
public void setCount(String count) {
this.count = count;
}
@XmlElement(name="test-data")
public List<TestData> getTestData() {
return testData;
}
public void setTestData(List<TestData> testData) {
this.testData = testData;
}
}
Demo
Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.
package forum11221136;
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Tests.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum11221136/input.xml");
Tests tests = (Tests) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(tests, System.out);
}
}
You should be able to run the script typing:
$ chmod 755 ./scripts/replace-md5sums.py
$ ./scripts/replace-md5sums.py
There are times where the user you are currently logged with just don't have the permission to change file mode bits. In such cases if you have the root password you can change the file permission this way:
$ sudo chmod 755 ./scripts/replace-md5sums.py
here's the incantation for nginx, inside a
location / {
# Simple requests
if ($request_method ~* "(GET|POST)") {
add_header "Access-Control-Allow-Origin" *;
}
# Preflighted requests
if ($request_method = OPTIONS ) {
add_header "Access-Control-Allow-Origin" *;
add_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, HEAD";
add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept";
}
}
If you have shell access you may use mysqldump
to dump the content of database1.table1
and pipe it to mysql
to database2
. The problem here is that table1
is still table1
.
mysqldump --user=user1 --password=password1 database1 table1 \
| mysql --user=user2 --password=password2 database2
Maybe you need to rename table1
to table2
with another query. On the other way you might use sed to change table1 to table2 between the to pipes.
mysqldump --user=user1 --password=password1 database1 table1 \
| sed -e 's/`table1`/`table2`/' \
| mysql --user=user2 --password=password2 database2
If table2 already exists, you might add the parameters to the first mysqldump which dont let create the table-creates.
mysqldump --no-create-info --no-create-db --user=user1 --password=password1 database1 table1 \
| sed -e 's/`table1`/`table2`/' \
| mysql --user=user2 --password=password2 database2

from { transform: rotate(0deg); }
to { transform: rotate(359deg); }
}

Here's a useful gradient so you can prove it is spinning (if its a circle):

First, the class must implements the click listenener :
implements OnItemClickListener
Then set a listener to the ListView
yourList.setOnItemclickListener(this);
And finally, create the clic method:
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "You Clicked at ",
Toast.LENGTH_SHORT).show();
}
In a nutshell :
-> Git Merge: It will simply merge your local changes and remote changes, and that will create another commit history record
-> Git Rebase: It will put your changes above all new remote changes, and rewrite commit history, so your commit history will be much cleaner than git merge. Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

The documentation of MySQL says :
CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.
So, it would seem normal that those two instruction do the same.
Maven is trying to download m2e's lifecycle-mapping artifact, which M2E uses to determine how to process plugins within Eclipse (adding source folders, etc.). For some reason this artifact cannot be downloaded. Do you have an internet connection? Can other artifacts be downloaded from repositories? Proxy settings?
For more details from Maven, try turning M2E debug output on (Settings/Maven/Debug Output checkbox) and it might give you more details as to why it cannot download from the repository.
If you could provide some reason as to why you need to replace the label with a div, that would certainly help...

I agree with @Richard Morgan ... what you are doing should be working, so more information may be needed.
Microsoft has some suggestions on options to protect your Excel 2003 worksheets.
Here is a little more info ...
From help files (Protect Method):
expression.Protect(Password, Structure, Windows)
expression Required. An expression that returns a Workbook object.
Password Optional Variant. A string that specifies a case-sensitive password for the worksheet or workbook. If this argument is omitted, you can unprotect the worksheet or workbook without using a password. Otherwise, you must specify the password to unprotect the worksheet or workbook. If you forget the password, you cannot unprotect the worksheet or workbook. It's a good idea to keep a list of your passwords and their corresponding document names in a safe place.
Structure Optional Variant. True to protect the structure of the workbook (the relative position of the sheets). The default value is False.
Windows Optional Variant. True to protect the workbook windows. If this argument is omitted, the windows aren’t protected.
ActiveWorkbook.Protect Password:="password", Structure:=True, Windows:=True
If you want to work at the worksheet level, I used something similar years ago when I needed to protect/unprotect:
Sub ProtectSheet()
ActiveSheet.Protect "password", True, True
End Sub
Sub UnProtectSheet()
ActiveSheet.Unprotect "password"
End Sub
Sub protectAll()
Dim myCount
Dim i
myCount = Application.Sheets.Count
Sheets(1).Select
For i = 1 To myCount
ActiveSheet.Protect "password", true, true
If i = myCount Then
End
End If
ActiveSheet.Next.Select
Next i
End Sub
I will suggest to use Object.assign
within a forEach()
loop so that the objects are copied and does not affect the original array of objects
var res = [];
array.forEach(function(item) {
var tempItem = Object.assign({}, item);
delete tempItem.bad;
res.push(tempItem);
});
console.log(res);
None of these answer were working for me on my macbook pro. So what i had to do was go to:
Preferences -> Source Code -> Code Formatting -> C# source code.
From here I could change my style and spacing tabs etc. This is the only project i have where the lead developer has different formatting than i do. It was a pain in the butt that my IDE would format my code different than theirs.
This is against the very definition of an iterator, which is a pointer to an object, plus information about how to get to the next object.
An iterator does not know how many more times it will be able to iterate until terminating. This could be infinite, so infinity might be your answer.

On Oracle XE this works:
SELECT 'DROP TABLE "' || TABLE_NAME || '";'
FROM USER_TABLES
WHERE TABLE_NAME LIKE 'YOURTABLEPREFIX%'
Or if you want to remove the constraints and free up space as well, use this:
SELECT 'DROP TABLE "' || TABLE_NAME || '" cascade constraints PURGE;'
FROM USER_TABLES
WHERE TABLE_NAME LIKE 'YOURTABLEPREFIX%'
Which will generate a bunch of DROP TABLE cascade constraints PURGE
statements...
For VIEWS
use this:
SELECT 'DROP VIEW "' || VIEW_NAME || '";'
FROM USER_VIEWS
WHERE VIEW_NAME LIKE 'YOURVIEWPREFIX%'

Open a Windows PowerShell window and type:
notepad $profile
Then create a function, such as:
function goSomewhereThenOpenGoogleThenDeleteSomething {
cd C:\Users\
Start-Process -FilePath "http://www.google.com"
rm fileName.txt
}
Then type this under the function name:
Set-Alias google goSomewhereThenOpenGoogleThenDeleteSomething
Now you can type the word "google" into Windows PowerShell and have it execute the code within your function!

Recovering stashes that were cleared/dropped erroneously
If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
following incantation to get a list of stashes that are still in your repository, but not reachable any more:
git fsck --unreachable |
grep commit | cut -d\ -f3 |
xargs git log --merges --no-walk --grep=WIP
This helped me better than the accepted answer with the same scenario.
You can also try this

Promise returned from $http
can not be binded directly (I dont exactly know why).
I'm using wrapping service that works perfectly for me:
.factory('DocumentsList', function($http, $q){
var d = $q.defer();
$http.get('/DocumentsList').success(function(data){
d.resolve(data);
});
return d.promise;
});
and bind to it in controller:
function Ctrl($scope, DocumentsList) {
$scope.Documents = DocumentsList;
...
}
UPDATE!:
In Angular 1.2 auto-unwrap promises was removed. See http://docs.angularjs.org/guide/migration#templates-no-longer-automatically-unwrap-promises
Margin="1,2,3,4"
It is also possible to specify just two sizes like this:
Margin="1,2"
Finally you can specify a single size:
Margin="1"
The order is the same as in WinForms.
Most of these work! BUT for a quick single line (low resource) call:
$array = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' );
echo $array[key($array)];
// key($array) -> will return the first key (which is 4 in this example)
Although this works, and decently well, please also see my additional answer: https://stackoverflow.com/a/48410351/1804013
In gitk --all
:
Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)
It would be cool if gitk
had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.
Even if you're normally a command-line junkie like myself, git gui
and gitk
are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)
gitk
is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.
I don't even have a graphical file browser open, but I love gitk/git gui.
By default, a grid item cannot be smaller than the size of its content.
Grid items have an initial size of min-width: auto
and min-height: auto
.
You can override this behavior by setting grid items to min-width: 0
, min-height: 0
or overflow
with any value other than visible
.
From the spec:
6.6. Automatic Minimum Size of Grid Items
To provide a more reasonable default minimum size for grid items, this specification defines that the
auto
value ofmin-width
/min-height
also applies an automatic minimum size in the specified axis to grid items whoseoverflow
isvisible
. (The effect is analogous to the automatic minimum size imposed on flex items.)
Here's a more detailed explanation covering flex items, but it applies to grid items, as well:
This post also covers potential problems with nested containers and known rendering differences among major browsers.
To fix your layout, make these adjustments to your code:
.month-grid {
display: grid;
grid-template: repeat(6, 1fr) / repeat(7, 1fr);
background: #fff;
grid-gap: 2px;
min-height: 0; /* NEW */
min-width: 0; /* NEW; needed for Firefox */
}
.day-item {
padding: 10px;
background: #DFE7E7;
overflow: hidden; /* NEW */
min-width: 0; /* NEW; needed for Firefox */
}
1fr
vs minmax(0, 1fr)
The solution above operates at the grid item level. For a container level solution, see this post:

fwrite()
is a smidgen faster and file_put_contents()
is just a wrapper around those three methods anyway, so you would lose the overhead.
Article
file_put_contents(file,data,mode,context):
The file_put_contents
writes a string to a file.
This function follows these rules when accessing a file.If FILE_USE_INCLUDE_PATH is set, check the include path for a copy of filename Create the file if it does not exist then Open the file and Lock the file if LOCK_EX is set and If FILE_APPEND is set, move to the end of the file. Otherwise, clear the file content Write the data into the file and Close the file and release any locks. This function returns the number of the character written into the file on success, or FALSE on failure.
fwrite(file,string,length):
The fwrite
writes to an open file.The function will stop at the end of the file or when it reaches the specified length,
whichever comes first.This function returns the number of bytes written or FALSE on failure.
error 'Class' does not name a type
Just in case someone does the same idiotic thing I did ... I was creating a small test program from scratch and I typed Class instead of class (with a small C). I didn't take any notice of the quotes in the error message and spent a little too long not understanding my problem.
My search for a solution brought me here so I guess the same could happen to someone else.
Why all people want to use '==' instead of simple '=' ? It is bad habit! It used only in [[ ]] expression. And in (( )) too. But you may use just = too! It work well in any case. If you use numbers, not strings use not parcing to strings and then compare like strings but compare numbers. like that
let -i i=5 # garantee that i is nubmber
test $i -eq 5 && echo "$i is equal 5" || echo "$i not equal 5"
It's match better and quicker. I'm expert in C/C++, Java, JavaScript. But if I use bash i never use '==' instead '='. Why you do so?
Probably part of Open Graph Protocol for Facebook.
Edit: guess not only Facebook - that's only one example of using it.
If you want to send as Cc using MimeMessageHelper
List<String> emails= new ArrayList();
email.add("email1");
email.add("email2");
for (String string : emails) {
message.addCc(string);
}
Same you can use to add multiple recipient.
You can set any pointer to NULL
, though NULL
is simply defined as 0 in C++:
myObject *foo = NULL;
Also note that NULL
is defined if you include standard headers, but is not built into the language itself. If NULL
is undefined, you can use 0 instead, or include this:
#ifndef NULL
#define NULL 0
#endif
As an aside, if you really want to set an object, not a pointer, to NULL
, you can read about the Null Object Pattern.
Your methods are missing the static
keyword. Change
function getInstanceByName($name=''){
to
public static function getInstanceByName($name=''){
if you want to call them statically.
Note that static methods (and Singletons) are death to testability.
Also note that you are doing way too much work in the constructor, especially all that querying shouldn't be in there. All your constructor is supposed to do is set the object into a valid state. If you have to have data from outside the class to do that consider injecting it instead of pulling it. Also note that constructors cannot return anything. They will always return void so all these return false
statements do nothing but end the construction.
I had the same problem and, after a day of research, I came up with this solution: http://jsfiddle.net/konstantc/4jkef3a1/

I know this question is pretty old but I thought that my solution can be of use to others that encounter this problem. Hope it helps.
You have four main options for converting types in pandas:
to_numeric()
- provides functionality to safely convert non-numeric types (e.g. strings) to a suitable numeric type. (See also to_datetime()
and to_timedelta()
.)
astype()
- convert (almost) any type to (almost) any other type (even if it's not necessarily sensible to do so). Also allows you to convert to categorial types (very useful).
infer_objects()
- a utility method to convert object columns holding Python objects to a pandas type if possible.
convert_dtypes()
- convert DataFrame columns to the "best possible" dtype that supports pd.NA
(pandas' object to indicate a missing value).
Read on for more detailed explanations and usage of each of these methods.
to_numeric()
The best way to convert one or more columns of a DataFrame to numeric values is to use pandas.to_numeric()
.
This function will try to change non-numeric objects (such as strings) into integers or floating point numbers as appropriate.
The input to to_numeric()
is a Series or a single column of a DataFrame.
>>> s = pd.Series(["8", 6, "7.5", 3, "0.9"]) # mixed string and numeric values
>>> s
0 8
1 6
2 7.5
3 3
4 0.9
dtype: object
>>> pd.to_numeric(s) # convert everything to float values
0 8.0
1 6.0
2 7.5
3 3.0
4 0.9
dtype: float64
As you can see, a new Series is returned. Remember to assign this output to a variable or column name to continue using it:
# convert Series
my_series = pd.to_numeric(my_series)
# convert column "a" of a DataFrame
df["a"] = pd.to_numeric(df["a"])
You can also use it to convert multiple columns of a DataFrame via the apply()
method:
# convert all columns of DataFrame
df = df.apply(pd.to_numeric) # convert all columns of DataFrame
# convert just columns "a" and "b"
df[["a", "b"]] = df[["a", "b"]].apply(pd.to_numeric)
As long as your values can all be converted, that's probably all you need.
But what if some values can't be converted to a numeric type?
to_numeric()
also takes an errors
keyword argument that allows you to force non-numeric values to be NaN
, or simply ignore columns containing these values.
Here's an example using a Series of strings s
which has the object dtype:
>>> s = pd.Series(['1', '2', '4.7', 'pandas', '10'])
>>> s
0 1
1 2
2 4.7
3 pandas
4 10
dtype: object
The default behaviour is to raise if it can't convert a value. In this case, it can't cope with the string 'pandas':
>>> pd.to_numeric(s) # or pd.to_numeric(s, errors='raise')
ValueError: Unable to parse string
Rather than fail, we might want 'pandas' to be considered a missing/bad numeric value. We can coerce invalid values to NaN
as follows using the errors
keyword argument:
>>> pd.to_numeric(s, errors='coerce')
0 1.0
1 2.0
2 4.7
3 NaN
4 10.0
dtype: float64
The third option for errors
is just to ignore the operation if an invalid value is encountered:
>>> pd.to_numeric(s, errors='ignore')
# the original Series is returned untouched
This last option is particularly useful when you want to convert your entire DataFrame, but don't not know which of our columns can be converted reliably to a numeric type. In that case just write:
df.apply(pd.to_numeric, errors='ignore')
The function will be applied to each column of the DataFrame. Columns that can be converted to a numeric type will be converted, while columns that cannot (e.g. they contain non-digit strings or dates) will be left alone.
By default, conversion with to_numeric()
will give you either a int64
or float64
dtype (or whatever integer width is native to your platform).
That's usually what you want, but what if you wanted to save some memory and use a more compact dtype, like float32
, or int8
?
to_numeric()
gives you the option to downcast to either 'integer', 'signed', 'unsigned', 'float'. Here's an example for a simple series s
of integer type:
>>> s = pd.Series([1, 2, -7])
>>> s
0 1
1 2
2 -7
dtype: int64
Downcasting to 'integer' uses the smallest possible integer that can hold the values:
>>> pd.to_numeric(s, downcast='integer')
0 1
1 2
2 -7
dtype: int8
Downcasting to 'float' similarly picks a smaller than normal floating type:
>>> pd.to_numeric(s, downcast='float')
0 1.0
1 2.0
2 -7.0
dtype: float32
astype()
The astype()
method enables you to be explicit about the dtype you want your DataFrame or Series to have. It's very versatile in that you can try and go from one type to the any other.
Just pick a type: you can use a NumPy dtype (e.g. np.int16
), some Python types (e.g. bool), or pandas-specific types (like the categorical dtype).
Call the method on the object you want to convert and astype()
will try and convert it for you:
# convert all DataFrame columns to the int64 dtype
df = df.astype(int)
# convert column "a" to int64 dtype and "b" to complex type
df = df.astype({"a": int, "b": complex})
# convert Series to float16 type
s = s.astype(np.float16)
# convert Series to Python strings
s = s.astype(str)
# convert Series to categorical type - see docs for more details
s = s.astype('category')
Notice I said "try" - if astype()
does not know how to convert a value in the Series or DataFrame, it will raise an error. For example if you have a NaN
or inf
value you'll get an error trying to convert it to an integer.
As of pandas 0.20.0, this error can be suppressed by passing errors='ignore'
. Your original object will be return untouched.
astype()
is powerful, but it will sometimes convert values "incorrectly". For example:
>>> s = pd.Series([1, 2, -7])
>>> s
0 1
1 2
2 -7
dtype: int64
These are small integers, so how about converting to an unsigned 8-bit type to save memory?
>>> s.astype(np.uint8)
0 1
1 2
2 249
dtype: uint8
The conversion worked, but the -7 was wrapped round to become 249 (i.e. 28 - 7)!
Trying to downcast using pd.to_numeric(s, downcast='unsigned')
instead could help prevent this error.
infer_objects()
Version 0.21.0 of pandas introduced the method infer_objects()
for converting columns of a DataFrame that have an object datatype to a more specific type (soft conversions).
For example, here's a DataFrame with two columns of object type. One holds actual integers and the other holds strings representing integers:
>>> df = pd.DataFrame({'a': [7, 1, 5], 'b': ['3','2','1']}, dtype='object')
>>> df.dtypes
a object
b object
dtype: object
Using infer_objects()
, you can change the type of column 'a' to int64:
>>> df = df.infer_objects()
>>> df.dtypes
a int64
b object
dtype: object
Column 'b' has been left alone since its values were strings, not integers. If you wanted to try and force the conversion of both columns to an integer type, you could use df.astype(int)
instead.
convert_dtypes()
Version 1.0 and above includes a method convert_dtypes()
to convert Series and DataFrame columns to the best possible dtype that supports the pd.NA
missing value.
Here "best possible" means the type most suited to hold the values. For example, this a pandas integer type if all of the values are integers (or missing values): an object column of Python integer objects is converted to Int64
, a column of NumPy int32
values will become the pandas dtype Int32
.
With our object
DataFrame df
, we get the following result:
>>> df.convert_dtypes().dtypes
a Int64
b string
dtype: object
Since column 'a' held integer values, it was converted to the Int64
type (which is capable of holding missing values, unlike int64
).
Column 'b' contained string objects, so was changed to pandas' string
dtype.
By default, this method will infer the type from object values in each column. We can change this by passing infer_objects=False
:
>>> df.convert_dtypes(infer_objects=False).dtypes
a object
b string
dtype: object
Now column 'a' remained an object column: pandas knows it can be described as an 'integer' column (internally it ran infer_dtype
) but didn't infer exactly what dtype of integer it should have so did not convert it. Column 'b' was again converted to 'string' dtype as it was recognised as holding 'string' values.
Similar to what Mark E has proposed, you have to come up with your own. Just to help you a bit, there is a neat article http://gleichmann.wordpress.com/2008/01/15/building-your-own-literals-in-java-tuples-and-maps/ which gives you a really neat way of creating tuples and maps that might be something you might want to consider.
PHP's strlen()
function returns the number of ASCII characters.
strlen('borsc')
-> 5 (bytes)
strlen('boršc')
-> 7 (bytes)
$limit_in_kBytes = 20000;
$pointer = 0;
while(strlen($your_string) > (($pointer + 1) * $limit_in_kBytes)){
$str_to_handle = substr($your_string, ($pointer * $limit_in_kBytes ), $limit_in_kBytes);
// here you can handle (0 - n) parts of string
$pointer++;
}
$str_to_handle = substr($your_string, ($pointer * $limit_in_kBytes), $limit_in_kBytes);
// here you can handle last part of string
.. or you can use a function like this:
function parseStrToArr($string, $limit_in_kBytes){
$ret = array();
$pointer = 0;
while(strlen($string) > (($pointer + 1) * $limit_in_kBytes)){
$ret[] = substr($string, ($pointer * $limit_in_kBytes ), $limit_in_kBytes);
$pointer++;
}
$ret[] = substr($string, ($pointer * $limit_in_kBytes), $limit_in_kBytes);
return $ret;
}
$arr = parseStrToArr($your_string, $limit_in_kBytes = 20000);
For full numbers (non-floats) in Angular you can use:
if (Number.isInteger(yourVariable)) {
...
}
This works regardless of the size of its contents

Are you running Skype? This has been the best solution I have found to get rid of the "cannot empty the clipboard error" in Excel 2007 & 2010. Delete the Skype add-on in IE and/or Firefox and good-bye annoying error!
In reply to rjacobs7 post on February 28, 2011
Cannot clear clipboard error - Windows 7, Excel 2010 - This error occurs nearly every time a drag and drop of cell contents is attempted. I've had this same error over the past 10 years on older computers and older versions of Windows and Office. It has now reoccurred with a new laptop running Windows 7 64 bit and Office 2010. The issue can be replicated only if a browser - IE or Firefox - is open at the same time that Excel is open. Having Word and/or Outlook open at the same time will not cause the problem to occur unless a browser is also open. This error is extremely irritating and no solutions from Microsoft or other posts on this issue resolve it.
I have a solution - at least for me! Delete the Skype add-in in IE and Firefox and the "cannot clear clipboard" error after a drag and drop goes away when IE and/or Firefox are running. Apparently some sort of memory-management issue with Skype, Office and the browsers.

I solved this issue by doing like that:
insert into my_table(my_field_0, ..., my_field_n) values(my_value_0, ..., my_value_n)
import java.util.Scanner;
public class Duplicates {
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
int number = console.nextInt();
String numb = "" + number;
int leng = numb.length()-1;
if (numb.charAt(0) != numb.charAt(1)) {
System.out.print(numb.substring(0,1));
}
for (int i = 0; i < leng; i++){
if (numb.charAt(i)==numb.charAt(i+1)){
System.out.print(numb.substring(i,i+1));
}
else {
System.out.print(numb.substring(i+1,i+2));
}
}
}
}
Another way to do this is to reassign df
based on a cross section of df
, using the .xs method.
>>> df
a
b c
0 1 2
1 3 4
>>> df = df.xs('a', axis=1, drop_level=True)
# 'a' : key on which to get cross section
# axis=1 : get cross section of column
# drop_level=True : returns cross section without the multilevel index
>>> df
b c
0 1 2
1 3 4

Another crazy possibility: If you follow a simple source control arrangement of putting Branch\Main, Main, and Release next to each other and you somehow end up adding an existing project from Main instead of Branch\Main (assuming your working solution is Branch\Main), you may see this error.
The solution is simple: reference the right project!
I tried all of the above suggestions, which did not work for me, but I found how to fix the error in my case.
The following steps made the project compile succesfully:
In project explorer, right-click on project, select “properties” In the tree on the right, go to Java build path. Select the tab “libraries”. Click “Add library”. Select JRE system library. Click next. Select radio button Alternate JRE. Click “installed JRE’s”. Select the JRE with the right version. Click Appy and close. In the next screen, click finish. In the properties window, click Apply and close. In the project explorer, right-click your pom.xml and select run as > maven build In the goal textbox, write “install”. Click Run.
This made the project build succesfully in my case.
Position absolute fixes it for me. I suggest also adding a semi-colon if you haven't already.
.container {
width: 22.5%;
size: 22.5% 22.5%;

min-height: 20%;

}
The most "foolproof" way is to check for the availability of URL:
public boolean isURL(String url) {
try {
(new java.net.URL(url)).openStream().close();
return true;
} catch (Exception ex) { }
return false;
}
Use forward slashes to specify the UNC Path:
open('//HOST/share/path/to/file')
(if your Python client code is also running under Windows)
For example:
lst_points = [[313, 262, 470, 482], [551, 254, 697, 449]]
lst_s_points = [" ".join(map(str, lst)) for lst in lst_points]
print lst_s_points
# ['313 262 470 482', '551 254 697 449']
As to me, I want to add a str
before each str list:
# here o means class, other four points means coordinate
print ['0 ' + " ".join(map(str, lst)) for lst in lst_points]
# ['0 313 262 470 482', '0 551 254 697 449']
Or single list:
lst = [313, 262, 470, 482]
lst_str = [str(i) for i in lst]
print lst_str, ", ".join(lst_str)
# ['313', '262', '470', '482'], 313, 262, 470, 482
lst_str = map(str, lst)
print lst_str, ", ".join(lst_str)
# ['313', '262', '470', '482'], 313, 262, 470, 482
$("#mydropdown option").length
Or if you already got a reference to it,
$(myDropdown).find("option").length
Most common case of this error happening is using template that is generating the control then changing the way id
and/or name
are being generated by 'overriding' default template with something like
@Html.TextBoxFor(m => m, new {Name = ViewData["Name"], id = ViewData["UniqueId"]} )
and then forgetting to change ValidationMessageFor
to
@Html.ValidationMessageFor(m => m, null, new { data_valmsg_for = ViewData["Name"] })
Hope this saves you some time.
The guide by Ani Menon (thx!) almost worked for me on windows 10, i just had to get a newer winutils.exe off that git (currently hadoop-2.8.1): https://github.com/steveloughran/winutils
From here:
The function
ord()
gets the int value of the char. And in case you want to convert back after playing with the number, functionchr()
does the trick.
>>> ord('a')
97
>>> chr(97)
'a'
>>> chr(ord('a') + 3)
'd'
>>>
In Python 2, there was also the unichr
function, returning the Unicode character whose ordinal is the unichr
argument:
>>> unichr(97)
u'a'
>>> unichr(1234)
u'\u04d2'
In Python 3 you can use chr
instead of unichr
.
Are we talking about standard java.io.FileReader
? Won't work, but it's not hard without it.
/src/main/resources
maven directory contents are placed in the root of your CLASSPATH, so you can simply retrieve it using:
InputStream is = getClass().getResourceAsStream("/storedProcedures.sql");
If the result is not null
(resource not found), feel free to wrap it in a reader:
Reader reader = new InputStreamReader(is);
Of course you can.
One thing should be noted however: The INSERT INTO SELECT
statement copies data from one table and inserts it into another table AND requires that data types in source and target tables match. If data types from given table columns does not match (i.e. trying to insert VARCHAR
into INT
, or TINYINT
intoINT
) the MySQL server will throw an SQL Error (1366)
.
So be careful.
Here is the syntax of the command:
INSERT INTO table2 (column1, column2, column3)
SELECT column1, column2, column3 FROM table1
WHERE condition;
Side note: There is a way to circumvent different column types insertion problem by using casting in your SELECT
, for example:
SELECT CAST('qwerty' AS CHAR CHARACTER SET utf8) COLLATE utf8_bin;
This conversion (CAST()
is synonym of CONVERT()
) is very useful if your tables have different character sets on the same table column (which can potentially lead to data loss if not handled properly).
Just type javac
. If it is installed you get usage information, otherwise it would just ask if you would like to install Java.
Your return function is in line of def function(main function), you must give one tab to it. And Use
%%debug
instead of
%debug
to debug the whole cell not only line. Hope, maybe this will help you.
I have found a way to use JSONP
method in $http
directly and with support of params
in the config object:
params = {
'a': b,
'callback': 'JSON_CALLBACK'
};
$http({
url: url,
method: 'JSONP',
params: params
})
Use Convert.ToDouble(value)
rather than (double)value
. It takes an object
and supports all of the types you asked for! :)
Also, your method is always returning a string
in the code above; I'd recommend having the method indicate so, and give it a more obvious name (public string FormatLargeNumber(object value)
)
A solution to this is to serve your code, and make it run on a server, you could use web server for chrome to easily serve your pages.
This is only a temporary workaround and not a real fix.
After having this happen to me and not being pleased with the current responses I went to work trying to figure it out from the AOSP source. I have found a REAL solution.
First off, a bit of (simplified) background on how Android installs and updates
The first time an app is installed:
The APK file is saved as
/data/app/<full.package.name>-1.apk (1.apk)
When the app is to be updated:
The updated APK file is saved as:
/data/app/<full.package.name>-2.apk (2.apk)
The first version (1.apk) gets deleted.
On our next update(s):
- The new APK is saved as (1.apk) and (2.apk) is deleted (Repeat forever).
The issue that most of us are having happens when the application is updated, but deleting of the old APK fails. Which itself does not yet cause the update to fail, but it does cause there to be two APK files in /data/app
.
The next time you try to update the app the system can't move its temporary file because neither (1.apk) nor (2.apk) are empty. Since File#renameTo(File) doesn't throw an exception but instead returns a boolean PackageManager, it doesn't have any way to tell why it returns INSTALL_FAILED_INSUFFICIENT_STORAGE even though the failure had nothing to do with the amount of free space.
Run:
adb shell "pm uninstall <full.packge.name>"
adb shell "rm -rf /data/app/<full.package.name>-*"
OR
Uninstall the app
Use your favorite method to delete BOTH:
/data/app/<full.package.name>-1.apk
/data/app/<full.package.name>-2.apk
Make sure nothing else blocks future installs in a similar way. In my case I had a /data/app-lib/<full.package.name>-1
directory lingering around! In this case, an install to the SD card worked, and a subsequent move to internal memory, too. (Creating /data/app-lib/<full.package.name>
without the -1
ending.)
The code for installing to external storage is significantly different which does not have the same problems
Uninstalling the app only deletes one version of the APK file in /data/app
. That's why you can reinstall it once, but not update it.
The amount of free space in an emulator isn't really relevant when this bug occurs
In my case, my JSON object didn't have any existing Array in it, so I had to create array element first and then had to push the element.
elementToPush = [1, 2, 3]
if (!obj.arr) this.$set(obj, "arr", [])
obj.arr.push(elementToPush)
(This answer may not be relevant to this particular question, but may help someone else)
You could use the round function. If you use no second parameter (# of significant digits) then I think you will get the behavior you want.
IDLE output.
>>> round(2.99999999999)
3
>>> round(2.6)
3
>>> round(2.5)
3
>>> round(2.4)

To make life easier when entering multiple dates/times it is possible to use a custom format to remove the need to enter the colon, and the leading "hour" 0. This however requires a second field for the numerical date to be stored, as the displayed date from the custom format is in base 10.
Displaying a number as a time (no need to enter colons, but no time conversion)
For displaying the times on the sheet, and for entering them without having to type the colon set the cell format to custom and use:
0/:00
Then enter your time. For example, if you wanted to enter 62:30, then you would simply type 6230 and your custom format would visually insert a colon 2 decimal points from the right.
If you only need to display the times, stop here.
Converting number to time
If you need to be able to calculate with the times, you will need to convert them from base 10 into the time format.
This can be done with the following formula (change A2
to the relevant cell reference):
=TIME(0,TRUNC(A2/100),MOD(A2,100))
=TIME
starts the number to time conversion0,
at the beginning of the formula, as the format is always hh,mm,ss
(to display hours and minutes instead of minutes and seconds, place the 0 at the end of the formula).TRUNC(A2/100),
discards the rightmost 2 digits.MOD(A2,100)
keeps the rightmost 2 digits and discards everything to the left.The above formula was found and adapted from this article: PC Mag.com - Easy Date and Time Entry in Excel
Alternatively, you could skip the 0/:00
custom formatting, and just enter your time in a cell to be referenced of the edge of the visible workspace or on another sheet as you would for the custom formatting (ie: 6230 for 62:30)
Then change the display format of the cells with the formula to [m]:ss
as @Sean Chessire suggested.
Here is a screen shot to show what I mean.
I came up with something using HTML + CSS only. Hope it works for you

sorry guys, except page reload method(flickering), none of them works for me (:key didn't worked).
and i found this method from old vue.js forum which is works for me:
https://github.com/vuejs/Discussion/issues/356
<template>
<div v-if="show">
<button @click="rerender">re-render</button>
</div>
</template>
<script>
export default {
data(){
return {show:true}
},
methods:{
rerender(){
this.show = false
this.$nextTick(() => {
this.show = true
console.log('re-render start')
this.$nextTick(() => {
console.log('re-render end')
})
})
}
}
}
</script>
In addition to everything else that has been said, you can call DefaultIfEmpty()
before you call Single()
. This will ensure that your sequence contains something and thereby averts the InvalidOperationException "Sequence contains no elements". For example:
BlogPost post = (from p in dc.BlogPosts
where p.BlogPostID == ID
select p).DefaultIfEmpty().Single();
One solution which avoids MultiIndex is to create a new datetime
column setting day = 1. Then group by this column.
df = pd.DataFrame({'Date': pd.to_datetime(['2017-10-05', '2017-10-20', '2017-10-01', '2017-09-01']),
'Values': [5, 10, 15, 20]})
# normalize day to beginning of month, 4 alternative methods below
df['YearMonth'] = df['Date'] + pd.offsets.MonthEnd(-1) + pd.offsets.Day(1)
df['YearMonth'] = df['Date'] - pd.to_timedelta(df['Date'].dt.day-1, unit='D')
df['YearMonth'] = df['Date'].map(lambda dt: dt.replace(day=1))
df['YearMonth'] = df['Date'].dt.normalize().map(pd.tseries.offsets.MonthBegin().rollback)
Then use groupby
as normal:
g = df.groupby('YearMonth')
res = g['Values'].sum()
# YearMonth
# 2017-09-01 20
# 2017-10-01 30
# Name: Values, dtype: int64
pd.Grouper
The subtle benefit of this solution is, unlike pd.Grouper
, the grouper index is normalized to the beginning of each month rather than the end, and therefore you can easily extract groups via get_group
:
some_group = g.get_group('2017-10-01')
Calculating the last day of October is slightly more cumbersome. pd.Grouper
, as of v0.23, does support a convention
parameter, but this is only applicable for a PeriodIndex
grouper.
An alternative to the above idea is to convert to a string, e.g. convert datetime 2017-10-XX
to string '2017-10'
. However, this is not recommended since you lose all the efficiency benefits of a datetime
series (stored internally as numerical data in a contiguous memory block) versus an object
series of strings (stored as an array of pointers).
I'd call the column "gender".
Data Type Bytes Taken Number/Range of Values
------------------------------------------------
TinyINT 1 255 (zero to 255)
INT 4 - 2,147,483,648 to 2,147,483,647
BIT 1 (2 if 9+ columns) 2 (0 and 1)
CHAR(1) 1 26 if case insensitive, 52 otherwise
The BIT data type can be ruled out because it only supports two possible genders which is inadequate. While INT supports more than two options, it takes 4 bytes -- performance will be better with a smaller/more narrow data type.
CHAR(1)
has the edge over TinyINT - both take the same number of bytes, but CHAR provides a more narrow number of values. Using CHAR(1)
would make using "m", "f",etc natural keys, vs the use of numeric data which are referred to as surrogate/artificial keys. CHAR(1)
is also supported on any database, should there be a need to port.
I would use Option 2: CHAR(1).
An index on the gender column likely would not help because there's no value in an index on a low cardinality column. Meaning, there's not enough variety in the values for the index to provide any value.
The Bootstrap version will be stated at the top of the CSS file. Simply open it and look at the top of the file.

Using Math.Round()
:
int percentComplete = (int)Math.Round((double)(100 * complete) / total);
or manually rounding:
int percentComplete = (int)(0.5f + ((100f * complete) / total));
I made a simple JQuery plugin for this if anyone is interested.
Components control views (html). They also communicate with other components and services to bring functionality to your app.
Modules consist of one or more components. They do not control any html. Your modules declare which components can be used by components belonging to other modules, which classes will be injected by the dependency injector and which component gets bootstrapped. Modules allow you to manage your components to bring modularity to your app.
The .NET Assembly loader:
This assembly does not match what was requested and therefore you get this error.
In simple words, it can't find the assembly that was referenced. Make sure it can find the right assembly by putting it in the GAC or in the application path. Also see https://docs.microsoft.com/archive/blogs/junfeng/the-located-assemblys-manifest-definition-with-name-xxx-dll-does-not-match-the-assembly-reference.
You need a spring-security-config.jar
on your classpath.
The exception means that the security:
xml namescape cannot be handled by spring "parsers". They are implementations of the NamespaceHandler
interface, so you need a handler that knows how to process <security:
tags. That's the SecurityNamespaceHandler
located in spring-security-config
If you're only looking for a webkit version this is nifty: http://s3.amazonaws.com/37assets/svn/463-single_spinner.html from http://37signals.com/svn/posts/2577-loading-spinner-animation-using-css-and-webkit
I like plugin https://github.com/hazzik/livequery It works without timers!
Simple usage
$('.some:visible').livequery( function(){ ... } );
But you need to fix a mistake. Replace line
$jQlq.registerPlugin('append', 'prepend', 'after', 'before', 'wrap', 'attr', 'removeAttr', 'addClass', 'removeClass', 'toggleClass', 'empty', 'remove', 'html', 'prop', 'removeProp');
to
$jQlq.registerPlugin('show', 'append', 'prepend', 'after', 'before', 'wrap', 'attr', 'removeAttr', 'addClass', 'removeClass', 'toggleClass', 'empty', 'remove', 'html', 'prop', 'removeProp');
You can use a simple "null function" for this, for example:
func Use(vals ...interface{}) {
for _, val := range vals {
_ = val
}
}
Which you can use like so:
package main
func main() {
a := "declared and not used"
b := "another declared and not used"
c := 123
Use(a, b, c)
}
There's also a package for this so you don't have to define the Use
function every time:
import (
"github.com/lunux2008/xulu"
)
func main() {
// [..]
xulu.Use(a, b, c)
}
You need both a value and a field to assign it to. The value is TableField + 1
, so the assignment is:
SET TableField = TableField + 1
My Problem:
docker run <IMAGE_NAME>
docker ps -a
I could see two containers. docker run <IMAGE_NAME>
command, new image was getting createdSolution: To work on the same container you created in the first place run follow these steps
docker ps
to get container of your containerdocker container start <CONTAINER_ID>
to start existing containerdocker exec -it <CONTAINER_ID> /bin/bash
If the class implements comparable, you could also do
int compRes = a.compareTo(b);
if(compRes < 0 || compRes > 0)
System.out.println("not equal");
else
System.out.println("equal);
doesn't use a !
, though not particularly useful, or readable....
If you need to print the number you can use printf
System.out.printf("%02d", num);
You can use
String.format("%02d", num);
or
(num < 10 ? "0" : "") + num;
or
(""+(100+num)).substring(1);
short read:
Flattening a tensor means to remove all of the dimensions except for one. This is exactly what the Flatten layer do.
long read:
If we take the original model (with the Flatten layer) created in consideration we can get the following model summary:
Layer (type) Output Shape Param #
=================================================================
D16 (Dense) (None, 3, 16) 48
_________________________________________________________________
A (Activation) (None, 3, 16) 0
_________________________________________________________________
F (Flatten) (None, 48) 0
_________________________________________________________________
D4 (Dense) (None, 4) 196
=================================================================
Total params: 244
Trainable params: 244
Non-trainable params: 0
For this summary the next image will hopefully provide little more sense on the input and output sizes for each layer.
The output shape for the Flatten layer as you can read is (None, 48)
. Here is the tip. You should read it (1, 48)
or (2, 48)
or ... or (16, 48)
... or (32, 48)
, ...
In fact, None
on that position means any batch size. For the inputs to recall, the first dimension means the batch size and the second means the number of input features.
The role of the Flatten layer in Keras is super simple:
A flatten operation on a tensor reshapes the tensor to have the shape that is equal to the number of elements contained in tensor non including the batch dimension.
Note: I used the model.summary()
method to provide the output shape and parameter details.
You can do this with pure CSS but you will need to hard code the offset scroll amounts, which may not be ideal should you be changing page content- or should dimensions of your content change on say window resize.
You're likely best placed to use e.g. jQuery, specifically:
$('html, body').stop().animate({
scrollTop: element.offset().top
}, 1000);
A complete implementation may be:
$('#up, #down').on('click', function(e){
e.preventDefault();
var target= $(this).get(0).id == 'up' ? $('#down') : $('#up');
$('html, body').stop().animate({
scrollTop: target.offset().top
}, 1000);
});
Where element
is the target element to scroll to and 1000
is the delay in ms before completion.
The benefit being, no matter what changes to your content dimensions, the function will not need to be altered.
An array is a pointer. It points to the start of a sequence of "objects".
If we do this: ìnt arr[10];
, then arr
is a pointer to a memory location, from which ten integers follow. They are uninitialised, but the memory is allocated. It is exactly the same as doing int *arr = new int[10];
.
What I would do, is create my own custom Date helper that looks like this :
var DateHelper = {_x000D_
addDays : function(aDate, numberOfDays) {_x000D_
aDate.setDate(aDate.getDate() + numberOfDays); // Add numberOfDays_x000D_
return aDate; // Return the date_x000D_
},_x000D_
format : function format(date) {_x000D_
return [_x000D_
("0" + date.getDate()).slice(-2), // Get day and pad it with zeroes_x000D_
("0" + (date.getMonth()+1)).slice(-2), // Get month and pad it with zeroes_x000D_
date.getFullYear() // Get full year_x000D_
].join('/'); // Glue the pieces together_x000D_
}_x000D_
}_x000D_
_x000D_
// With this helper, you can now just use one line of readable code to :_x000D_
// ---------------------------------------------------------------------_x000D_
// 1. Get the current date_x000D_
// 2. Add 20 days_x000D_
// 3. Format it_x000D_
// 4. Output it_x000D_
// ---------------------------------------------------------------------_x000D_
document.body.innerHTML = DateHelper.format(DateHelper.addDays(new Date(), 20));
_x000D_
(see also this Fiddle)
in SQL 2008 a new TSQL statement "MERGE" is introduced which performs insert, update, or delete operations on a target table based on the results of a join with a source table. You can synchronize two tables by inserting, updating, or deleting rows in one table based on differences found in the other table.

Speaking for the JS only solutions, I've found that, inelegant as it may be, a simple indexed for
loop is more performant than its alternatives.
Extracting single property from a 100000 element array (via jsPerf)
Traditional for loop 368 Ops/sec
var vals=[];
for(var i=0;i<testArray.length;i++){
vals.push(testArray[i].val);
}
ES6 for..of loop 303 Ops/sec
var vals=[];
for(var item of testArray){
vals.push(item.val);
}
Array.prototype.map 19 Ops/sec
var vals = testArray.map(function(a) {return a.val;});
TL;DR - .map() is slow, but feel free to use it if you feel readability is worth more than performance.
Edit #2: 6/2019 - jsPerf link broken, removed.
This is another way to specify the range of the bit-vector.
x +: N, The start position of the vector is given by x and you count up from x by N.
There is also
x -: N, in this case the start position is x and you count down from x by N.
N is a constant and x is an expression that can contain iterators.
It has a couple of benefits -
It makes the code more readable.
You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.
I was having this issue too. The scraper shows the right information, but the share url was still populated with old data.
The way I got around this was to use the feed method, instead of share, and then populate the data manually (which isn't exposed with the share method)
Something like this:
shareToFB = () => {
window.FB.ui({
method: 'feed',
link: `signup.yourdomain.com/?referrer=${this.props.subscriber.sid}`,
name: 'THIS WILL OVERRIDE OG:TITLE TAG',
description: 'THIS WILL OVERRIDE OG:DESCRIPTION TAG',
caption: 'THIS WILL OVERRIDE THE OG:URL TAG'
});
};
If anyone wants to get only the selected value on click to an option, he can do the follow:
$('.chosen-select').on('change', function(evt, params) {
var selectedValue = params.selected;
console.log(selectedValue);
});
You cannot append to an existing xlsx file with xlsxwriter
.
There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close()
which will then write all of the information to your xlsx file.
Similarly, you can use a method of your own to "append" to xlsx documents. I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet, and then I had to append a new sheet each time a test started as well. The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns...
i.e.
cells = []
for row in range(sheet.nrows):
cells.append([])
for col in range(sheet.ncols):
cells[row].append(workbook.cell(row, col).value)
You don't need arrays, though. For example, this works perfectly fine:
import xlrd
import xlsxwriter
from os.path import expanduser
home = expanduser("~")
# this writes test data to an excel file
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
sheet1 = wb.add_worksheet()
for row in range(10):
for col in range(20):
sheet1.write(row, col, "test ({}, {})".format(row, col))
wb.close()
# open the file for reading
wbRD = xlrd.open_workbook("{}/Desktop/test.xlsx".format(home))
sheets = wbRD.sheets()
# open the same file for writing (just don't write yet)
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
# run through the sheets and store sheets in workbook
# this still doesn't write to the file yet
for sheet in sheets: # write data from old file
newSheet = wb.add_worksheet(sheet.name)
for row in range(sheet.nrows):
for col in range(sheet.ncols):
newSheet.write(row, col, sheet.cell(row, col).value)
for row in range(10, 20): # write NEW data
for col in range(20):
newSheet.write(row, col, "test ({}, {})".format(row, col))
wb.close() # THIS writes
However, I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over (which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call .close()
).
Perhaps:
> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)
Q#1: I would guess that it's somewhere on your MySQL server? Q#2: Yes, this is possible. You have to establish a connection via Server Administration. There you can clone any table or the entire database.
This tutorial might be useful.
EDIT
Since the provided link is no longer active, here's a SO answer outlining the process of creating a DB backup in Workbench.
Please remove e.preventDefault()
, because event.cancelable
of touchmove is false
.
So you can't call this method.
a = range(1,10)
itemsToRemove = set([2, 3, 7])
b = filter(lambda x: x not in itemsToRemove, a)
or
b = [x for x in a if x not in itemsToRemove]
Don't create the set inside the lambda
or inside the comprehension. If you do, it'll be recreated on every iteration, defeating the point of using a set at all.
And now there is readxl:
The readxl package makes it easy to get data out of Excel and into R. Compared to the existing packages (e.g. gdata, xlsx, xlsReadWrite etc) readxl has no external dependencies so it's easy to install and use on all operating systems. It is designed to work with tabular data stored in a single sheet.
readxl is built on top of the libxls C library, which abstracts away many of the complexities of the underlying binary format.
It supports both the legacy .xls format and .xlsx
readxl is available from CRAN, or you can install it from github with:
# install.packages("devtools")
devtools::install_github("hadley/readxl")
Usage
library(readxl)
# read_excel reads both xls and xlsx files
read_excel("my-old-spreadsheet.xls")
read_excel("my-new-spreadsheet.xlsx")
# Specify sheet with a number or name
read_excel("my-spreadsheet.xls", sheet = "data")
read_excel("my-spreadsheet.xls", sheet = 2)
# If NAs are represented by something other than blank cells,
# set the na argument
read_excel("my-spreadsheet.xls", na = "NA")
Note that while the description says 'no external dependencies', it does require the Rcpp
package, which in turn requires Rtools (for Windows) or Xcode (for OSX), which are dependencies external to R. Though many people have them installed for other reasons.
Such difference between the output of du -sh
and df -h
may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted
to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.
or can do this...
set all btn ( class name like : .btn-
+ $theme-colors: map-merge
) styles at one time :
@each $color, $value in $theme-colors {
.btn-#{$color} {
@include button-variant($value, $value,
// modify
$hover-background: lighten($value, 7.5%),
$hover-border: lighten($value, 10%),
$active-background: lighten($value, 10%),
$active-border: lighten($value, 12.5%)
// /modify
);
}
}
// code from "node_modules/bootstrap/scss/_buttons.scss"
should add into your customization scss file.
Try using head or tail. If you want the 5 most-recently modified files:
ls -1t | head -5
The -1 (that's a one) says one file per line and the head says take the first 5 entries.
If you want the last 5 try
ls -1t | tail -5
Using something like selection.node().getBBox()
you get values like
{
height: 5,
width: 5,
y: 50,
x: 20
}
Use selection.node().getBoundingClientRect()
You can use SWITCH() function to evaluate multiple criteria to color the cell. The node <BackgroundColor>
is the cell fill, <Color>
is font color.

Inside of VBS you can access parameters with
Wscript.Arguments(0)
Wscript.Arguments(1)
and so on. The number of parameter:
Wscript.Arguments.Count
Using lodash _.values(object)
_.values({"id": 1, "second": "abcd"})
[ 1, 'abcd' ]
lodash
includes a whole bunch of other functions to work with arrays, objects, collections, strings, and more that you wish were built into JavaScript (and actually seem to slowly be making their way into the language).
Use dotPeek
Select the .dll
to decompile
That's it
Empty dictionaries evaluate to False
in Python:
>>> dct = {}
>>> bool(dct)
False
>>> not dct
True
>>>
Thus, your isEmpty
function is unnecessary. All you need to do is:
def onMessage(self, socket, message):
if not self.users:
socket.send("Nobody is online, please use REGISTER command" \
" in order to register into the server")
else:
socket.send("ONLINE " + ' ' .join(self.users.keys()))
It could be possible that the compiler translates Set(Integer) to Set(Object) in java byte code. If this is the case, Set(Integer) would be used only at compile phase for syntax checking.
Here is the code for it.

Because I don't like to have duplicate files (log4j.properties in test and main), and I have quite many test classes, they each runwith SpringJUnit4ClassRunner class, so I have to customize it. This is what I use:
import java.io.FileNotFoundException;
import org.junit.runners.model.InitializationError;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.util.Log4jConfigurer;
public class MySpringJUnit4ClassRunner extends SpringJUnit4ClassRunner {
static {
String log4jLocation = "classpath:log4j-oops.properties";
try {
Log4jConfigurer.initLogging(log4jLocation);
} catch (FileNotFoundException ex) {
System.err.println("Cannot Initialize log4j at location: " + log4jLocation);
}
}
public MySpringJUnit4ClassRunner(Class<?> clazz) throws InitializationError {
super(clazz);
}
}
When you use it, replace SpringJUnit4ClassRunner with MySpringJUnit4ClassRunner
@RunWith(MySpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:conf/applicationContext.xml")
public class TestOrderController {
private Logger LOG = LoggerFactory.getLogger(this.getClass());
private MockMvc mockMvc;
...
}
Good question. Yes, one can do this more efficiently. Your CPU can extract both the quotient and the remainder of the ratio of two integers in a single operation. In <stdlib.h>
, the function that exposes this CPU operation is called div()
. In your psuedocode, you'd use it something like this:
function to_tuple(x):
qr = div(x, 1000)
ms = qr.rem
qr = div(qr.quot, 60)
s = qr.rem
qr = div(qr.quot, 60)
m = qr.rem
h = qr.quot
A less efficient answer would use the /
and %
operators separately. However, if you need both quotient and remainder, anyway, then you might as well call the more efficient div()
.
Adding everything together, it is a good idea to trim for extra white space at beginning of string. Otherwise, .substring(0,1).toUpperCase will try to capitalize a white space.
public String capitalizeFirstLetter(String original) {
if (original == null || original.length() == 0) {
return original;
}
return original.trim().substring(0, 1).toUpperCase() + original.substring(1);
}
I define a category that lets me filter using a block, like this:
@implementation NSMutableArray (Filtering)
- (void)filterUsingTest:(BOOL (^)(id obj, NSUInteger idx))predicate {
NSMutableIndexSet *indexesFailingTest = [[NSMutableIndexSet alloc] init];
NSUInteger index = 0;
for (id object in self) {
if (!predicate(object, index)) {
[indexesFailingTest addIndex:index];
}
++index;
}
[self removeObjectsAtIndexes:indexesFailingTest];
[indexesFailingTest release];
}
@end
which can then be used like this:
[myMutableArray filterUsingTest:^BOOL(id obj, NSUInteger idx) {
return [self doIWantToKeepThisObject:obj atIndex:idx];
}];
You need to be in a synchronized
block in order for Object.wait()
to work.
Also, I recommend looking at the concurrency packages instead of the old school threading packages. They are safer and way easier to work with.
Happy coding.
EDIT
I assumed you meant Object.wait()
as your exception is what happens when you try to gain access without holding the objects lock.
Semaphore can also be used as a ... semaphore. For example if you have multiple process enqueuing data to a queue, and only one task consuming data from the queue. If you don't want your consuming task to constantly poll the queue for available data, you can use semaphore.
Here the semaphore is not used as an exclusion mechanism, but as a signaling mechanism. The consuming task is waiting on the semaphore The producing task are posting on the semaphore.
This way the consuming task is running when and only when there is data to be dequeued
For me, I had an issue until I removed the padding. It looks like there is a bug on certain devices that doesn't alter the size of the view to accommodate the padding, and instead compresses the contents.
Remove padding
, use layout_margin
instead.
Component:
import { Component, AfterViewInit, ViewChild } from @angular/core;
import { MatPaginator } from @angular/material;
export class ClassName implements AfterViewInit {
@ViewChild(MatPaginator) paginator: MatPaginator;
length = 1000;
pageSize = 10;
pageSizeOptions: number[] = [5, 10, 25, 100];
ngAfterViewInit() {
this.paginator.page.subscribe(
(event) => console.log(event)
);
}
HTML
<mat-paginator
[length]="length"

[pageSizeOptions]="pageSizeOptions"

I would rather use OnPreDrawListener() instead of addOnGlobalLayoutListener(), since it is called a bit earlier than other listeners.
view.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener()
{
@Override
public boolean onPreDraw()
{
if (view.getViewTreeObserver().isAlive())
view.getViewTreeObserver().removeOnPreDrawListener(this);
// put your code here
return true;
}
});
Don't forget:
div.something.else {
// will only style a div with both, not just one or the other
}
LocalDate::plusMonths
Example:
LocalDate.now( )
.plusMonths( 1 );
Better to specify time zone.
LocalDate.now( ZoneId.of( "America/Montreal" )
.plusMonths( 1 );
The java.time framework is built into Java 8 and later. These classes supplant the old troublesome date-time classes such as java.util.Date
, .Calendar
, & java.text.SimpleDateFormat
. The Joda-Time team also advises migration to java.time.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.
Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.
If you want the date-only, use the LocalDate
class.
ZoneId z = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( z );
today.toString(): 2017-01-23
Add a month.
LocalDate oneMonthLater = today.plusMonths( 1 );
oneMonthLater.toString(): 2017-02-23
Perhaps you want a time-of-day along with the date.
First get the current moment in UTC with a resolution of nanoseconds.
Instant instant = Instant.now();
Adding a month means determining dates. And determining dates means applying a time zone. For any given moment, the date varies around the world with a new day dawning earlier to the east. So adjust that Instant
into a time zone.
ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );
Now add your month. Let java.time handle Leap month, and the fact that months vary in length.
ZonedDateTime zdtMonthLater = zdt.plusMonths( 1 );
You might want to adjust the time-of-day to the first moment of the day when making this kind of calculation. That first moment is not always 00:00:00.0
so let java.time determine the time-of-day.
ZonedDateTime zdtMonthLaterStartOfDay = zdtMonthLater.toLocalDate().atStartOfDay( zoneId );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
Update: The Joda-Time project is now in maintenance mode. Its team advises migration to the java.time classes. I am leaving this section intact for posterity.
The Joda-Time library offers a method to add months in a smart way.
DateTimeZone timeZone = DateTimeZone.forID( "Europe/Paris" );
DateTime now = DateTime.now( timeZone );
DateTime nextMonth = now.plusMonths( 1 );
You might want to focus on the day by adjust the time-of-day to the first moment of the day.
DateTime nextMonth = now.plusMonths( 1 ).withTimeAtStartOfDay();

There is no good answer as Python and Java are both specifications for which there are many different implementations. For example, CPython, IronPython, Jython, and PyPy are just a handful of Python implementations out there. For Java, there is the HotSpot VM, the Mac OS X Java VM, OpenJRE, etc. Jython generates Java bytecode, and so it would be using more-or-less the same underlying Java. CPython implements quite a handful of things directly in C, so it is very fast, but then again Java VMs also implement many functions in C. You would probably have to measure on a function-by-function basis and across a variety of interpreters and VMs in order to make any reasonable statement.
In Windows, you can use /
in your path just like Linux or macOS in all places as long as you use PowerShell as your command-line interface. It comes pre-installed on Windows and it supports many Linux commands like ls
command.
If you use Windows Command Prompt (the one that appears when you type cmd
in Windows Start Menu), you need to specify paths with \
just inside it. You can use /
paths in all other places (code editor, Python interactive mode, etc.).
Here is an example of how you can create a struct that causes the error message "Attempted to read or write protected memory. This is often an indication that other memory is corrupt". The difference between success and failure is very subtle.
The following unit test demonstrates the problem.
See if you can work out what went wrong.
[Test]
public void Test()
{
var bar = new MyClass
{
Foo = 500
};
bar.Foo += 500;
Assert.That(bar.Foo.Value.Amount, Is.EqualTo(1000));
}
private class MyClass
{
public MyStruct? Foo { get; set; }
}
private struct MyStruct
{
public decimal Amount { get; private set; }
public MyStruct(decimal amount) : this()
{
Amount = amount;
}
public static MyStruct operator +(MyStruct x, MyStruct y)
{
return new MyStruct(x.Amount + y.Amount);
}
public static MyStruct operator +(MyStruct x, decimal y)
{
return new MyStruct(x.Amount + y);
}
public static implicit operator MyStruct(int value)
{
return new MyStruct(value);
}
public static implicit operator MyStruct(decimal value)
{
return new MyStruct(value);
}
}
you can also copy the gradlew.bat into you root folder and copy the gradlew-wrapper into gradlew folder.
that's work for me.
If you want to have your vars in files under group_vars, just move them here. Vars can be in the inventory ([group:vars] section) but also (and foremost) in files under group_vars
or hosts_vars
.
For instance, with your example above, you can move your vars for group tests
in the file group_vars/tests
:
