I had this error coming up between 2 Linux boxes. Easily solved by installing RSYNC on the remote box as well as the local one.
A simple swap is far better for "moving something up" in an ArrayList:
if(i > 0) {
Item toMove = arrayList.get(i);
arrayList.set(i, arrayList.get(i-1));
arrayList.set(i-1, toMove);
}
Because an ArrayList uses an array, if you remove an item from an ArrayList, it has to "shift" all the elements after that item upward to fill in the gap in the array. If you insert an item, it has to shift all the elements after that item to make room to insert it. These shifts can get very expensive if your array is very big. Since you know that you want to end up with the same number of elements in the list, doing a swap like this allows you to "move" an element to another location in the list very efficiently.
As Chris Buckler and Michal Kreuzman point out, there is even a handy method in the Collections class to reduce these three lines of code to one:
Collections.swap(arrayList, i, i-1);
I had issue because my vim was not supporting clipboard:
vim --version | grep clip
-clipboard +insert_expand +path_extra +user_commands
+emacs_tags -mouseshape +startuptime -xterm_clipboard
I installed vim-gnome (which support clipboard) and then checked again:
vim --version | grep clipboard
+clipboard +insert_expand +path_extra +user_commands
+emacs_tags +mouseshape +startuptime +xterm_clipboard
Now I am able to copy and paste using "+y and "+p respectively.
See Java tools documentation for:
- The
java
tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class'smain
method.- The
javaw
command is identical tojava
, except that withjavaw
there is no associated console window. Usejavaw
when you don't want a command prompt window to appear.
javaws
command, the "Java Web Start command"The
javaws
command launches Java Web Start, which is the reference implementation of the Java Network Launching Protocol (JNLP). Java Web Start launches Java applications/applets hosted on a network.
If a JNLP file is specified,javaws
will launch the Java application/applet specified in the JNLP file.
Thejavaws
launcher has a set of options that are supported in the current release. However, the options may be removed in a future release.

For System.Timers.Timer
, according to MSDN documentation, http://msdn.microsoft.com/en-us/library/system.timers.timer.enabled.aspx:
If the interval is set after the Timer has started, the count is reset. For example, if you set the interval to 5 seconds and then set the Enabled property to true, the count starts at the time Enabled is set. If you reset the interval to 10 seconds when count is 3 seconds, the Elapsed event is raised for the first time 13 seconds after Enabled was set to true.
So,
const double TIMEOUT = 5000; // milliseconds
aTimer = new System.Timers.Timer(TIMEOUT);
aTimer.Start(); // timer start running
:
:
aTimer.Interval = TIMEOUT; // restart the timer
GnuPG (with binary name gpg
) is an application used for public key encryption using the OpenPGP protocol, but also verification of signatures (cryptographic signatures, that also can validate the publisher if used correctly). To some extend, you could say it's for OpenPGP what OpenSSL is for X.509 and TLS.
Unlike most Linux distributions (which make heavy use of GnuPG for ensuring untampered software within their package repositories), Mac OS X does not bring GnuPG with the operating system, so you have to install it on your own.

If you have MAMP PRO you can set up a host like mysite.local, then add some options from the 'Advanced' panel in the main window. Just switch on the options 'Indexes' and 'MultiViews'. 'Includes' and 'FollowSymLinks' should already be checked.
If you merged the branch, then reverted the merge using a pull request and merged that pull request to revert.
The easiest way I felt was to:
git revert -m 1 xxxxxx
(if the revert was merged using a branch) or using git revert xxxxxx
if it was a simple revertYou cannot use IF control block OUTSIDE of functions. So that affects both of your queries.
Turn the EXISTS clause into a subquery instead within an IF function
SELECT IF( EXISTS(
SELECT *
FROM gdata_calendars
WHERE `group` = ? AND id = ?), 1, 0)
In fact, booleans are returned as 1 or 0
SELECT EXISTS(
SELECT *
FROM gdata_calendars
WHERE `group` = ? AND id = ?)
Using pathlib you can get the folder in which the current file is located. __file__
is the pathname of the file from which the module was loaded.

When the JVM
tries to run your application, it calls your main method statically; something like this:
LinkedList.main();
That means there is no instance of your LinkedList
class. In order to call your toString()
method, you can create a new instance of your LinkedList
class.
So the body of your main
method should be like this:
public static void main(String[] args){
// creating an instance of LinkedList class
LinkedList ll = new LinkedList();
// adding some data to the list
ll.insertFront(1);
ll.insertFront(2);
ll.insertFront(3);
ll.insertBack(4);
System.out.println(ll.toString());
}
If you use jQuery built-in after()
with empty value it will create a dynamic object that will match your :after
CSS selector.
$('.active').after().click(function () {
alert('clickable!');
});
See the jQuery documentation.
Perhaps this will work?
<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
<c:set var="myVar" value="${stat.first ? '' : myVar} ${currentItem}" />
</c:forEach>
Functional approach:
Python 3.x
>>> x = [1,2,3,2,2,2,3,4]
>>> list(filter((2).__ne__, x))
[1, 3, 3, 4]
or
>>> x = [1,2,3,2,2,2,3,4]
>>> list(filter(lambda a: a != 2, x))
[1, 3, 3, 4]
Python 2.x
>>> x = [1,2,3,2,2,2,3,4]
>>> filter(lambda a: a != 2, x)
[1, 3, 3, 4]
That's the function I wrote to get string in Unicode characters:
function nbUnicodeLength(string){
var stringIndex = 0;
var unicodeIndex = 0;
var length = string.length;
var second;
var first;
while (stringIndex < length) {
first = string.charCodeAt(stringIndex); // returns an integer between 0 and 65535 representing the UTF-16 code unit at the given index.
if (first >= 0xD800 && first <= 0xDBFF && string.length > stringIndex + 1) {
second = string.charCodeAt(stringIndex + 1);
if (second >= 0xDC00 && second <= 0xDFFF) {
stringIndex += 2;
} else {
stringIndex += 1;
}
} else {
stringIndex += 1;
}
unicodeIndex += 1;
}
return unicodeIndex;
}
Add the following to the top of your file # coding=utf-8
If you go to the link in the error you can seen the reason why:
Defining the Encoding
Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=
For a checked exception:
public class MyCustomException extends Exception { }
Technically, anything that extends Throwable
can be an thrown, but exceptions are generally extensions of the Exception
class so that they're checked exceptions (except RuntimeException or classes based on it, which are not checked), as opposed to the other common type of throwable, Error
s which usually are not something designed to be gracefully handled beyond the JVM internals.
You can also make exceptions non-public, but then you can only use them in the package that defines them, as opposed to across packages.
As far as throwing/catching custom exceptions, it works just like the built-in ones - throw via
throw new MyCustomException()
and catch via
catch (MyCustomException e) { }
For me it wasn't a port or service issue; I had to re-run the XAMPP setup script. Although this didn't directly fix the issue for me, the script was much more verbose than the XAMPP log, pointing me in the right direction to actually solve the problem.
From the XAMPP GUI, click on Shell, type set
, press Tab to autocomplete to the setup_xampp.bat
file, and then press Enter to run it.
In my case I got the following output:
[ERROR]: Test php.exe failed !!!
[ERROR]: Perhaps the Microsoft C++ 2008 runtime package is not installed.
[ERROR]: Please try to install the MS VC++ 2008 Redistributable Package from the Mircrosoft page first
[ERROR]: http://www.microsoft.com/en-us/download/details.aspx?id=5582
This particular error is misleading. Although it specifies the Visual C++ 2008 Redistributable Package, PHP 7.4.x requires the Visual C++ 2019 Redistributable Package.
After installing that and following the prompt to restart, sure enough I'm now able to start Apache as normal.
If you used
brew install python
before 'unlink' you got
brew info python

so do
brew unlink python && brew link python
and open a new terminal shell
python -V

You need to access the underlying buffer:
printf("%s\n", someString.c_str());
Or better use cout << someString << endl;
(you need to #include <iostream>
to use cout
)
Additionally you might want to import the std
namespace using using namespace std;
or prefix both string
and cout
with std::
.
Since you tagged it Rails, you can use truncate:
http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-truncate
Example:
truncate(@text, :length => 17)
Excerpt is nice to know too, it lets you display an excerpt of a text Like so:
excerpt('This is an example', 'an', :radius => 5)
# => ...s is an exam...
http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-excerpt
If you want detect when user scroll over certain div, you can do something like this:
window.onscroll = function() {
var distanceScrolled = document.documentElement.scrollTop;
console.log('Scrolled: ' + distanceScrolled);
}
For example, if your div appear after scroll until the position 112:
window.onscroll = function() {
var distanceScrolled = document.documentElement.scrollTop;
if (distanceScrolled > 112) {
do something...
}
}
But as you can see you don't need a div, just the offset distance you want something to happen.
Routes
export const MyRoutes: Routes = [
{ path: '/items/:id', component: MyComponent }
]
Component
import { ActivatedRoute } from '@angular/router';
public id: string;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.id = this.route.snapshot.paramMap.get('id');
}
If you don't want to go down the VBA path, there is this trick from a previous question.
Excel 2010: how to use autocomplete in validation list
It does add some annoying bulk to the top of your sheets, and potential maintenance (should you need more options, adding names of people from a staff list, new projects etc.) but works all the same.
There is a Win32 port of wget that works decently.
PowerShell's Invoke-WebRequest -Method Head
would work as well.
VI search and replace command examples
Let us say you would like to find a word called “foo” and replace with “bar”.
First hit [Esc]
key
Type : (colon) followed by %s/foo/bar/
and hit [Enter] key
:%s/foo/bar/
Testing this Javascript:
var arr = [1234563995.721, 12345691212.718, 1234568421.5891, 12345677093.49284];
var sum = 0;
for( var i = 0; i < arr.length; i++ ) {
sum += arr[i];
}
alert( "fMath(sum) = " + Math.round( sum * 1e12 ) / 1e12 );
alert( "fFixed(sum) = " + sum.toFixed( 5 ) );
Dont use Math.round( (## + ## + ... + ##) * 1e12) / 1e12
Instead, use ( ## + ## + ... + ##).toFixed(5) )
In IE 9, toFixed
works very well.
In Pyspark you can simply specify each condition separately:
val Lead_all = Leads.join(Utm_Master,
(Leaddetails.LeadSource == Utm_Master.LeadSource) &
(Leaddetails.Utm_Source == Utm_Master.Utm_Source) &
(Leaddetails.Utm_Medium == Utm_Master.Utm_Medium) &
(Leaddetails.Utm_Campaign == Utm_Master.Utm_Campaign))
Just be sure to use operators and parenthesis correctly.
Unfortunately, all of these solutions rely on specifying a fixed width. Since the tables are generated dynamically (statistical results pulled from a database), the width can not be known in advance.
The desired result can be achieved by wrapping the two tables within another table:
<table align="center"><tr><td>
//code for table on the left
</td><td>
//code for table on the right
</td></tr></table>
and the result is a perfectly centered pair of tables that responds fluidly to arbitrary widths and page (re)sizes (and the align="center" table attribute could be hoisted out into an outer div with margin autos).
I conclude that there are some layouts that can only be achieved with tables.
The problem is that your anonymous object property data-icon
has an invalid name. C# properties cannot have dashes in their names. There are two ways you can get around that:
Use an underscore instead of dash (MVC will automatically replace the underscore with a dash in the emitted HTML):
@Html.ActionLink("Edit", "edit", "markets",
new { id = 1 },
new {@class="ui-btn-right", data_icon="gear"})
Use the overload that takes in a dictionary:
@Html.ActionLink("Edit", "edit", "markets",
new { id = 1 },
new Dictionary<string, object> { { "class", "ui-btn-right" }, { "data-icon", "gear" } });
This worked for me.
create extension IF NOT EXISTS "uuid-ossp" schema pg_catalog version "1.1";
make sure the extension should by on pg_catalog and not in your schema...
You could just use this
FileOpen(1, "C:\my files\2010\SomeFileName.txt", OpenMode.Output)
FileClose(1)
This opens the file replaces whatever is in it and closes the file.
JPA is a specification to standardize ORM-APIs. Hibernate is a vendor of a JPA implementation. So if you use JPA with hibernate, you can use the standard JPA API, hibernate will be under the hood, offering some more non standard functions. See http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html_single/ and http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/
Subtract '0' like this:
int i = c - '0';
The C Standard guarantees each digit in the range '0'..'9'
is one greater than its previous digit (in section 5.2.1/3
of the C99 draft). The same counts for C++.
no fancy linq, not adding all the chars by hand, just plain and simple:
var str = "foo";
var sc = new SecureString();
foreach(char c in str) sc.appendChar(c);
For anyone who tried everything without luck, this is the only thing that got it working for me. For the multiline labels inside cell, try adding this magic line:
label.preferredMaxLayoutWidth = 200

You can upload files by dragging and dropping or by pointing and clicking. To upload folders, you must drag and drop them. Drag and drop functionality is supported only for the Chrome and Firefox browsers
Adding \n
and/or \r
in the middle of the string, and having a very long line of code, like in second example, doesn't feel right : when you read the code, you don't see the result, and you have to scroll.
In this kind of situations, I always use Heredoc (Or Nowdoc, if using PHP >= 5.3) : easy to write, easy to read, no need for super-long lines, ...
For instance :
$var = 'World';
$str = <<<MARKER
this is a very
long string that
doesn't require
horizontal scrolling,
and interpolates variables :
Hello, $var!
MARKER;
Just one thing : the end marker (and the ';
' after it) must be the only thing on its line : no space/tab before or after !
if anyone faced problem even after using return false;
. then use the below.
setTimeout(function(){document.location.href = "index.php"},500);
The problem is with slashes: your variable contains them and the final command will be something like sed "s/string/path/to/something/g"
, containing way too many slashes.
Since sed
can take any char as delimiter (without having to declare the new delimiter), you can try using another one that doesn't appear in your replacement string:
replacement="/my/path"
sed --expression "s@pattern@$replacement@"
Note that this is not bullet proof: if the replacement string later contains @
it will break for the same reason, and any backslash sequences like \1
will still be interpreted according to sed
rules. Using |
as a delimiter is also a nice option as it is similar in readability to /
.
Yes, the problem is that there are no commits in "bare". This is a problem with the first commit only, if you create the repos in the order (bare,alice). Try doing:
git push --set-upstream origin master
This would only be required the first time. Afterwards it should work normally.
As Chris Johnsen pointed out, you would not have this problem if your push.default was customized. I like upstream/tracking.
If you're looking for a document-level key event handling, then binding it during componentDidMount
is the best way (as shown by Brad Colthurst's codepen example):
class ActionPanel extends React.Component {
constructor(props){
super(props);
this.escFunction = this.escFunction.bind(this);
}
escFunction(event){
if(event.keyCode === 27) {
//Do whatever when esc is pressed
}
}
componentDidMount(){
document.addEventListener("keydown", this.escFunction, false);
}
componentWillUnmount(){
document.removeEventListener("keydown", this.escFunction, false);
}
render(){
return (
<input/>
)
}
}
Note that you should make sure to remove the key event listener on unmount to prevent potential errors and memory leaks.
EDIT: If you are using hooks, you can use this useEffect
structure to produce a similar effect:
const ActionPanel = (props) => {
const escFunction = useCallback((event) => {
if(event.keyCode === 27) {
//Do whatever when esc is pressed
}
}, []);
useEffect(() => {
document.addEventListener("keydown", escFunction, false);
return () => {
document.removeEventListener("keydown", escFunction, false);
};
}, []);
return (
<input />
)
};
public static void WriteLine(this List<int> theList)
{
foreach (int i in list)
{
Console.Write("{0}\t", t.ToString());
}
Console.WriteLine();
}
Then, later...
list.WriteLine();
Your code was very close to working.
Try using a regular csv.writer rather than a DictWriter. The latter is mainly used for writing a list of dictionaries.
Here's some code that writes each key/value pair on a separate row:
import csv
somedict = dict(raymond='red', rachel='blue', matthew='green')
with open('mycsvfile.csv','wb') as f:
w = csv.writer(f)
w.writerows(somedict.items())
If instead you want all the keys on one row and all the values on the next, that is also easy:
with open('mycsvfile.csv','wb') as f:
w = csv.writer(f)
w.writerow(somedict.keys())
w.writerow(somedict.values())
Pro tip: When developing code like this, set the writer to w = csv.writer(sys.stderr)
so you can more easily see what is being generated. When the logic is perfected, switch back to w = csv.writer(f)
.
If you prefer a code with a pretty look, you can do a break:
for(int j = 0; ; j++){
if(j < 6
&& j < ( (int) abc[j] & 0xff)){
break;
}
// Put your code here
}
Sonatype Nexus and Apache Maven are two pieces of software that often work together but they do very different parts of the job. Nexus provides a repository while Maven uses a repository to build software.
Here's a quote from "What is Nexus?":
Nexus manages software "artifacts" required for development. If you develop software, your builds can download dependencies from Nexus and can publish artifacts to Nexus creating a new way to share artifacts within an organization. While Central repository has always served as a great convenience for developers you shouldn't be hitting it directly. You should be proxying Central with Nexus and maintaining your own repositories to ensure stability within your organization. With Nexus you can completely control access to, and deployment of, every artifact in your organization from a single location.
And here is a quote from "Maven and Nexus Pro, Made for Each Other" explaining how Maven uses repositories:
Maven leverages the concept of a repository by retrieving the artifacts necessary to build an application and deploying the result of the build process into a repository. Maven uses the concept of structured repositories so components can be retrieved to support the build. These components or dependencies include libraries, frameworks, containers, etc. Maven can identify components in repositories, understand their dependencies, retrieve all that are needed for a successful build, and deploy its output back to repositories when the build is complete.
So, when you want to use both you will have a repository managed by Nexus and Maven will access this repository.
CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.
This is an old post, but thanks to this post I have found this:
\! echo 'some text';
Tested with MySQL 8 and working correctly. Cool right? :)
To avoid a panic on a zero length input, wrap the truncate operation in an if
input, _ := src.ReadString('\n')
var inputFmt string
if len(input) > 0 {
inputFmt = input[:len(input)-1]
}
// Do something with inputFmt
What's wrong with just invoking the commands?
foo:
echo line1
echo line2
....
And for your second question, you need to escape the $
by using $$
instead, i.e. bash -c '... echo $$a ...'
.
EDIT: Your example could be rewritten to a single line script like this:
gcc $(for i in `find`; do echo $i; done)
It is a unary "+" operator which yields a numeric expression. It would be the same as d*1
, I believe.
Let the modern java.time classes of JSR 310 automatically generate localized text, rather than hard-coding 12-hour clock and AM/PM.
LocalTime // Represent a time-of-day, without date, without time zone or offset-from-UTC.
.now( // Capture the current time-of-day as seen in a particular time zone.
ZoneId.of( "Africa/Casablanca" )
) // Returns a `LocalTime` object.
.format( // Generate text representing the value in our `LocalTime` object.
DateTimeFormatter // Class responsible for generating text representing the value of a java.time object.
.ofLocalizedTime( // Automatically localize the text being generated.
FormatStyle.SHORT // Specify how long or abbreviated the generated text should be.
) // Returns a `DateTimeFormatter` object.
.withLocale( Locale.US ) // Specifies a particular locale for the `DateTimeFormatter` rather than rely on the JVM’s current default locale. Returns another separate `DateTimeFormatter` object rather than altering the first, per immutable objects pattern.
) // Returns a `String` object.
10:31 AM
Rather than insisting on 12-hour clock with AM/PM, you may want to let java.time automatically localize for you. Call DateTimeFormatter.ofLocalizedTime
.
To localize, specify:
FormatStyle
to determine how long or abbreviated should the string be.Locale
to determine:
Here we get the current time-of-day as seen in a particular time zone. Then we generate text to represent that time. We localize to French language in Canada culture, then English language in US culture.
ZoneId z = ZoneId.of( "Asia/Tokyo" ) ;
LocalTime localTime = LocalTime.now( z ) ;
// Québec
Locale locale_fr_CA = Locale.CANADA_FRENCH ; // Or `Locale.US`, and so on.
DateTimeFormatter formatterQuébec = DateTimeFormatter.ofLocalizedTime( FormatStyle.SHORT ).withLocale( locale_fr_CA ) ;
String outputQuébec = localTime.format( formatterQuébec ) ;
System.out.println( outputQuébec ) ;
// US
Locale locale_en_US = Locale.US ;
DateTimeFormatter formatterUS = DateTimeFormatter.ofLocalizedTime( FormatStyle.SHORT ).withLocale( locale_en_US ) ;
String outputUS = localTime.format( formatterUS ) ;
System.out.println( outputUS ) ;

I found a way to display the Document Location module
in Office 2010.
File -> Options -> Quick Access Toolbar
From the
Choose commands

select All Commands
find "Document Location"
press the "Add>>"
button.
press OK
.
Viola, the file path is at the top of your 2010 office document.
If you are mocking the behavior (with something like doNothing()
) there should really be no need to call to verify*()
. That said, here's my stab at re-writing your test method:
@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
public void testProcessOrder() {
//Variables
InternalService is = new InternalService();
Order order = mock(Order.class);
//Mock Behavior
when(order.isSuccessful()).thenReturn(true);
mockStatic(Internalutils.class);
doNothing().when(InternalUtils.class); //This is the preferred way
//to mock static void methods.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
//Execute
is.processOrder(order);
//Verify
verifyStatic(InternalUtils.class); //Similar to how you mock static methods
//this is how you verify them.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
}
}
I grouped into four sections to better highlight what is going on:
I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.
This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.
Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.
This is when you call any method starting with verify
or assert
. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.
This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.
I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:
Also, you can just set the ViewName:
return View("ViewName");
Full controller example:
public ActionResult SomeAction() {
if (condition)
{
return View("CustomView");
}else{
return View();
}
}
This works on MVC 5.

"ASCII is a subset of UTF-8, so..." - so UTF-8 is a set? :)
In other words: any string build with code points
from x00 to x7F has indistinguishable representations (byte sequences) in ASCII and UTF-8. Converting such string is pointless.
Another HTML-based, client-side solution using markdown-it and jQuery. Below is a small HTML wrapper as a master document, that supports unlimited includes of markdown files, but not nested includes. Explanation is provided in the JS comments. Error handling is omitted.

Ionic Android emulator error INSTALL_FAILED_OLDER_SDK
So, basically it means that the installation has failed due to having an older SDK version than the targetSdkVersion specified in your app (it's a Gradle issue). Just edit the AndroidManifest.xml file and add the following code:
<uses-sdk android:minSdkVersion="19" android:targetSdkVersion="14"/>
_x000D_
After days looking for the solution, that's it.
Works fine for me!
For Bootstrap 4 you may have to use .modal-backdrop.show
and play around with !important
flag on both background-color
and opacity
.
E.g.
.modal-backdrop.show {
background-color: #f00;
opacity: 0.75;
}
I can't comment on Esben Skov Pedersen's answer directly, but using the following notation for links:
<a href="javascript:window.open('http://www.websiteofyourchoice.com');">Click here</a>
In Internet Explorer, the new browser window appears, but the current window navigates to a page which says "[Object]". To avoid this, simple put a "void(0)" behind the JavaScript function.
If a value contains a comma, a newline character or a double quote, then the string must be enclosed in double quotes. E.g: "Newline char in this field \n".
You can use below online tool to escape "" and , operators. https://www.freeformatter.com/csv-escape.html#ad-output
For the current date activity and complete activity for previous 30 days use this, since the SYSDATE is variable in a day the previous 30th day will not have the whole data for that day.
SELECT DATE_FORMAT(create_date, '%m/%d/%Y')
FROM mytable
WHERE create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND SYSDATE()
as amber and sinan have noted above, the javascritp '.split' method will work just fine. Just pass it the string separator(-) and the string that you intend to split('123-abc-itchy-knee') and it will do the rest.
var coolVar = '123-abc-itchy-knee';
var coolVarParts = coolVar.split('-'); // this is an array containing the items
var1=coolVarParts[0]; //this will retrieve 123
To access each item from the array just use the respective index(indices start at zero).
itemgetter
(see other answers) is (as I know) more efficient for large dictionaries but for the common case, I believe that d.get
wins. And it does not require an extra import
.
>>> d = {"aa": 3, "bb": 4, "cc": 2, "dd": 1}
>>> for k in sorted(d, key=d.get, reverse=True):
... k, d[k]
...
('bb', 4)
('aa', 3)
('cc', 2)
('dd', 1)
Note that alternatively you can set d.__getitem__
as key
function which may provide a small performance boost over d.get
.
The basic principle of centering a page is to have a body CSS and main_container CSS. It should look something like this:
body {
margin: 0;
padding: 0;
text-align: center;
}
#main_container {
margin: 0 auto;
text-align: left;
}
A cleaner way to specify the Gradle compiler arguments follow:
compileJava.options.compilerArgs = ['-Xlint:unchecked','-Xlint:deprecation']
sudo apt-get install --reinstall python-pkg-resources
fixed it for me in Debian. Seems like uninstalling some .deb packages (twisted set in my case) has broken the path python uses to find packages
So what are you doing is with append and concat is almost equivalent. The difference is the empty DataFrame. For some reason this causes a big slowdown, not sure exactly why, will have to look at some point. Below is a recreation of basically what you did.
I almost always use concat (though in this case they are equivalent, except for the empty frame); if you don't use the empty frame they will be the same speed.
In [17]: df1 = pd.DataFrame(dict(A = range(10000)),index=pd.date_range('20130101',periods=10000,freq='s'))
In [18]: df1
Out[18]:
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 10000 entries, 2013-01-01 00:00:00 to 2013-01-01 02:46:39
Freq: S
Data columns (total 1 columns):
A 10000 non-null values
dtypes: int64(1)
In [19]: df4 = pd.DataFrame()
The concat
In [20]: %timeit pd.concat([df1,df2,df3])
1000 loops, best of 3: 270 us per loop
This is equavalent of your append
In [21]: %timeit pd.concat([df4,df1,df2,df3])
10 loops, best of
3: 56.8 ms per loop
After few days, today I just resolved this problem. Generate ssh key, follow this article:
https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/
Declare it to
Then clone by command:
git clone [email protected]:my_group/my_repository.git
And no error happen.
The above problem
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
because have error when clone by HTTP protocol (curl
command).
And, you should increment buffer size:
git config --global http.postBuffer 524288000
Use urllib2 in combination with the brilliant BeautifulSoup library:
import urllib2
from BeautifulSoup import BeautifulSoup
# or if you're using BeautifulSoup4:
# from bs4 import BeautifulSoup
soup = BeautifulSoup(urllib2.urlopen('http://example.com').read())
for row in soup('table', {'class': 'spad'})[0].tbody('tr'):
tds = row('td')
print tds[0].string, tds[1].string
# will print date and sunrise
A generic solution like so
public static <X, Y, Z> Map<X, Z> transform(Map<X, Y> input,
Function<Y, Z> function) {
return input
.entrySet()
.stream()
.collect(
Collectors.toMap((entry) -> entry.getKey(),
(entry) -> function.apply(entry.getValue())));
}
Example
Map<String, String> input = new HashMap<String, String>();
input.put("string1", "42");
input.put("string2", "41");
Map<String, Integer> output = transform(input,
(val) -> Integer.parseInt(val));
Percent encoding. Replace the hash with %23
.
I had the same problem. Get the warning. Went to Data connections and deleted connection. Save, close reopen. Still get the warning. I use a xp/vista menu plugin for classic menus. I found under data, get external data, properties, uncheck the save query definition. Save close and reopen. That seemed to get rid of the warning. Just removing the connection does not work. You have to get rid of the query.
When you get a UnicodeEncodeError
, it means that somewhere in your code you convert directly a byte string to a unicode one. By default in Python 2 it uses ascii encoding, and utf8 encoding in Python3 (both may fail because not every byte is valid in either encoding)
To avoid that, you must use explicit decoding.
If you may have 2 different encoding in your input file, one of them accepts any byte (say UTF8 and Latin1), you can try to first convert a string with first and use the second one if a UnicodeDecodeError occurs.
def robust_decode(bs):
'''Takes a byte string as param and convert it into a unicode one.
First tries UTF8, and fallback to Latin1 if it fails'''
cr = None
try:
cr = bs.decode('utf8')
except UnicodeDecodeError:
cr = bs.decode('latin1')
return cr
If you do not know original encoding and do not care for non ascii character, you can set the optional errors
parameter of the decode
method to replace
. Any offending byte will be replaced (from the standard library documentation):
Replace with a suitable replacement character; Python will use the official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on decoding and ‘?’ on encoding.
bs.decode(errors='replace')
As a general rule, you can’t just set the color of a horizontal line with CSS like you would anything else. First of all, Internet Explorer needs the color in your CSS to read like this:
“color: #123455”
But Opera and Mozilla needs the color in your CSS to read like this:
“background-color: #123455”
So, you will need to add both options to your CSS.
Next, you will need to give the horizontal line some dimensions or it will default to the standard height, width and color set by your browser. Here is a sample code of what your CSS should look like to get the blue horizontal line.
hr {
border: 0;
width: 100%;
color: #123455;
background-color: #123455;
height: 5px;
}
Or you could just add the style to your HTML page directly when you insert a horizontal line, like this:
<hr style="background:#123455" />
Hope this helps.
Use the function to clear cookies:
function clearCookies($clearSession = false)
{
$past = time() - 3600;
if ($clearSession === false)
$sessionId = session_id();
foreach ($_COOKIE as $key => $value)
{
if ($clearSession !== false || $value !== $sessionId)
setcookie($key, $value, $past, '/');
}
}
If you pass true
then it clears session
data, otherwise session data is preserved.
Through trial and error, it seems if the user was originally created "without login" then this query
select * from sys.database_principals
will show authentication_type = 0 (NONE).
Apparently these users cannot be re-linked to any login (pre-existing or new, SQL or Windows) since this command:
alter user [TempUser] with login [TempLogin]
responds with the Remap Error "Msg 33016" shown in the question.
Also these users do not show up in classic (deprecating) SP report:
exec sp_change_users_login 'Report'
If anyone knows a way around this or how to change authentication_type, please comment.

RUN yum install php72w -y
ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]
The app returned the same error with json_decode and json_encode
Resolution
Install PHP Common that has json_encode and json_decode
yum install -y php72w-common-7.2.14-1.w7.x86_64
How to find the resolution?
I have another Docker File what build the container for the API and it has the order to install php-mysql client:
yum install php72w-mysql.x86_64 -y
If i use these image to mount the app, the json_encode and json_decode works!! Ok..... What dependencies does this have?

As BalusC indicated, the actionListener
by default swallows exceptions, but in JSF 2.0 there is a little more to this. Namely, it doesn't just swallows and logs, but actually publishes the exception.
This happens through a call like this:
context.getApplication().publishEvent(context, ExceptionQueuedEvent.class,
new ExceptionQueuedEventContext(context, exception, source, phaseId)
);
The default listener for this event is the ExceptionHandler
which for Mojarra is set to com.sun.faces.context.ExceptionHandlerImpl
. This implementation will basically rethrow any exception, except when it concerns an AbortProcessingException, which is logged. ActionListeners wrap the exception that is thrown by the client code in such an AbortProcessingException which explains why these are always logged.
This ExceptionHandler
can be replaced however in faces-config.xml with a custom implementation:
<exception-handlerfactory>
com.foo.myExceptionHandler
</exception-handlerfactory>
Instead of listening globally, a single bean can also listen to these events. The following is a proof of concept of this:
@ManagedBean
@RequestScoped
public class MyBean {
public void actionMethod(ActionEvent event) {
FacesContext.getCurrentInstance().getApplication().subscribeToEvent(ExceptionQueuedEvent.class, new SystemEventListener() {
@Override
public void processEvent(SystemEvent event) throws AbortProcessingException {
ExceptionQueuedEventContext content = (ExceptionQueuedEventContext)event.getSource();
throw new RuntimeException(content.getException());
}
@Override
public boolean isListenerForSource(Object source) {
return true;
}
});
throw new RuntimeException("test");
}
}
(note, this is not how one should normally code listeners, this is only for demonstration purposes!)
Calling this from a Facelet like this:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:body>
<h:form>
<h:commandButton value="test" actionListener="#{myBean.actionMethod}"/>
</h:form>
</h:body>
</html>
Will result in an error page being displayed.
You could try something like this in javascript:
var regex = /[^a-zA-Z]/g;
and have a keyup event.
$("#nameofInputbox").value.replace(regex, "");
SELECT * FROM table SAMPLE(10) WHERE ROWNUM <= 20;
This is more efficient as it doesn't need to sort the Table.
Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.
To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)
The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:
* ASP.NET * Advanced Windows Communication Foundation (WCF) functionality * .NET Framework Data Provider for Oracle * MSBuild for compiling
(SELECT CASE WHEN (SELECT Salary FROM tbl_Salary WHERE Code=102 AND Month=1 AND Year=2020 )=0 THEN 'Pending'

SOLVED: On Debian 10 by adding "EXPORT TERM=xterm" on the Script executed by CRONTAB (root) but executed as www-data.
$ crontab -e

If you're doing any sort of development you need to point to the JDK (Java Development Kit). Otherwise, you can point to the JRE (Java Runtime Environment).
The JDK contains everything the JRE has and more. If you're just executing Java programs, you can point to either the JRE or the JDK.
You should set JAVA_HOME
based on current Java you are using.
readlink
will print value of a symbolic link for current Java and sed
will adjust it to JRE directory:
export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")
If you want to set up JAVA_HOME to JDK you should go up one folder more:
export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:jre/bin/java::")
Try this method to get path of original
image captured by camera.
public String getOriginalImagePath() {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, null, null, null);
int column_index_data = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToLast();
return cursor.getString(column_index_data);
}
This method will return path of the last image captured by camera. So this path would be of original image not of thumbnail bitmap.
In case you want to see the local variables of a calling function use select-frame
before info locals
E.g.:
(gdb) bt

#1 0xfec36f39 in thr_kill () from /lib/libc.so.1

#3 0xfebc2961 in abort () from /lib/libc.so.1
#4 0xfebc2bef in _assert_c99 () from /lib/libc.so.1
#5 0x08053260 in main (argc=1, argv=0x8047958) at ber.c:480
(gdb) info locals
No symbol table info available.

If d is a dictionary, then d.get(k, v)
means, give me the value of k in d, unless k isn't there, in which case give me v. It's being used here to get the current count of the character, which should start at 0 if the character hasn't been encountered before.
Not sure if there's a convenient way, but you can just inspect your kafka/libs
folder. You should see files like kafka_2.10-0.8.2-beta.jar
, where 2.10
is Scala version and 0.8.2-beta
is Kafka version.
.class {
background-color:none;
}
This is not a valid property. W3C validator will display following error:

values during the development of specification of CSS.
When you pass the the System.Drawing.Image
type object to a method you are actually passing a copy of reference to that object.
So if inside that method you are loading a new image you are loading using new/copied reference. You are not making change in original.
YourMethod(System.Drawing.Image image)
{
//now this image is a new reference
//if you load a new image
image = new Image()..
//you are not changing the original reference you are just changing the copy of original reference
}
The following javascript will fade in an element from opacity 0 to whatever the opacity value was at the time of calling fade in. You can also set the duration of the animation which is nice:
function fadeIn(element) {
var duration = 0.5;
var interval = 10;//ms
var op = 0.0;
var iop = element.style.opacity;
var timer = setInterval(function () {
if (op >= iop) {
op = iop;
clearInterval(timer);
}
element.style.opacity = op;
op += iop/((1000/interval)*duration);
}, interval);
}
*Based on IBUs answer but modified to account for previous opacity value and ability to set duration, also removed irrelevant CSS changes it was making
This is such a basic thing to do I wouldn't use an external library (it will cause a dependency in your project that you probably don't need).
We have a class of static methods specifically crafted to do these sort of jobs. Because the code for this is so simple we let Hotspot do the optimization for us. This seems to be a theme in my code recently: write very simple (straightforward) code and let Hotspot do its magic. We rarely have performance issues around code like this - when a new VM version comes along you get all the extra speed benefits etc.
As much as I love Jakarta collections, they don't support Generics and use 1.4 as the LCD. I am wary of Google Collections because they are listed as Alpha support level!
June 2014:
This is the configuration I used and it working fine after banging my head on the wall for some days. I use Express 3.4 (I think is the same for Express 4.0)
var privateKey = fs.readFileSync('helpers/sslcert/key.pem', 'utf8');
var certificate = fs.readFileSync('helpers/sslcert/csr.pem', 'utf8');
files = ["COMODORSADomainValidationSecureServerCA.crt",
"COMODORSAAddTrustCA.crt",
"AddTrustExternalCARoot.crt"
];
ca = (function() {
var _i, _len, _results;
_results = [];
for (_i = 0, _len = files.length; _i < _len; _i++) {
file = files[_i];
_results.push(fs.readFileSync("helpers/sslcert/" + file));
}
return _results;
})();
var credentials = {ca:ca, key: privateKey, cert: certificate};
// process.env.PORT : Heroku Config environment
var port = process.env.PORT || 4000;
var app = express();
var server = http.createServer(app).listen(port, function() {
console.log('Express HTTP server listening on port ' + server.address().port);
});
https.createServer(credentials, app).listen(3000, function() {
console.log('Express HTTPS server listening on port ' + server.address().port);
});
// redirect all http requests to https
app.use(function(req, res, next) {
if(!req.secure) {
return res.redirect(['https://mydomain.com', req.url].join(''));
}
next();
});
Then I redirected the 80 and 443 ports:
sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 4000
sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 3000

For this, I prefer to keep a correct HTML semantic, and to use a CSS simple as possible.
Something like this would do the job :
label{
display: block;
float: left;
width : 120px;
}
One drawback however : you might have to pick the right label width for each form, and this is not easy if your labels can be dynamic (I18N labels for instance).
keras predict_classes (docs) outputs A numpy array of class predictions. Which in your model case, the index of neuron of highest activation from your last(softmax) layer. [[0]]
means that your model predicted that your test data is class 0. (usually you will be passing multiple image, and the result will look like [[0], [1], [1], [0]]
)
You must convert your actual label (e.g. 'cancer', 'not cancer'
) into binary encoding (0
for 'cancer', 1
for 'not cancer') for binary classification. Then you will interpret your sequence output of [[0]]
as having class label 'cancer'
I wrote this silly thing a long time ago and still actually use it now and then:
https://gist.github.com/kphretiq/e2f924416a326895233d
Basically, it does a "SHOW TABLES", then a "DESCRIBE " on each table, then spits it out as markdown.
Just edit below the "if name" and go. You'll need to have pymysql installed.
You can add this in your css file:
[data-role=page]{height: 100% !important; position:relative !important;}
[data-role=footer]{bottom:0; position:absolute !important; top: auto !important; width:100%;}
So the page data-role now have 100% height, and footer is in absolute position.
Also Yappo have wrote an excellent plugin that you can find here: jQuery Mobile in a iScroll plugin http://yappo.github.com/projects/jquery.mobile.iscroll/livedemo.html
hope you found the answer!
An answer update
You can now use the data-position="fixed"
attribute to keep your footer element on the bottom.

It is best practice to go asynchronous if you can do several things in parallel (no inter-dependencies). If you need it to complete to continue loading the next thing you could use synchronous, but note that this option is deprecated to avoid abuse of sync:
I prefer Font Awesome: http://fortawesome.github.io/Font-Awesome/icons/
The icon you would be looking for is fa-times
. It's as simple as this to use:
<button><i class="fa fa-times"></i> Close</button>
Use Random.nextInt(int).
In your case it would look something like this:
a[i][j] = r.nextInt(101);

Steps
Make a list of items, based on their weights
:
items = [1, 2, 3, 4, 5, 6]
probabilities= [0.1, 0.05, 0.05, 0.2, 0.4, 0.2]
# if the list of probs is normalized (sum(probs) == 1), omit this part
prob = sum(probabilities) # find sum of probs, to normalize them
c = (1.0)/prob # a multiplier to make a list of normalized probs
probabilities = map(lambda x: c*x, probabilities)
print probabilities
ml = max(probabilities, key=lambda x: len(str(x)) - str(x).find('.'))
ml = len(str(ml)) - str(ml).find('.') -1
amounts = [ int(x*(10**ml)) for x in probabilities]
itemsList = list()
for i in range(0, len(items)): # iterate through original items
itemsList += items[i:i+1]*amounts[i]
# choose from itemsList randomly
print itemsList
An optimization may be to normalize amounts by the greatest common divisor, to make the target list smaller.
Also, this might be interesting.
extern
declaration in the other file.static
. Such variables are said to have internal linkage.Consider following example:
void f(int i);
extern const int max = 10;
int n = 0;
int main()
{
int a;
//...
f(a);
//...
f(a);
//...
}
f
declares f
as a function with external linkage (default). Its definition must be provided later in this file or in other translation unit (given below).max
is defined as an integer constant. The default linkage for constants is internal. Its linkage is changed to external with the keyword extern
. So now max
can be accessed in other files. n
is defined as an integer variable. The default linkage for variables defined outside function bodies is external.#include <iostream>
using namespace std;
extern const int max;
extern int n;
static float z = 0.0;
void f(int i)
{
static int nCall = 0;
int a;
//...
nCall++;
n++;
//...
a = max * z;
//...
cout << "f() called " << nCall << " times." << endl;
}
max
is declared to have external linkage. A matching definition for max
(with external linkage) must appear in some file. (As in 1.cpp)n
is declared to have external linkage.z
is defined as a global variable with internal linkage.nCall
specifies nCall
to be a variable that retains its value across calls to function f()
. Unlike local variables with the default auto storage class, nCall
will be initialized only once at the start of the program and not once for each invocation of f()
. The storage class specifier static
affects the lifetime of the local variable and not its scope.NB: The keyword static
plays a double role. When used in the definitions of global variables, it specifies internal linkage. When used in the definitions of the local variables, it specifies that the lifetime of the variable is going to be the duration of the program instead of being the duration of the function.
Hope that helps!
Multiple attributes can be connected with an and
:
GroupMember.find_or_create_by_member_id_and_group_id(4, 7)
(use find_or_initialize_by
if you don't want to save the record right away)
Edit: The above method is deprecated in Rails 4. The new way to do it will be:
GroupMember.where(:member_id => 4, :group_id => 7).first_or_create
and
GroupMember.where(:member_id => 4, :group_id => 7).first_or_initialize
Edit 2: Not all of these were factored out of rails just the attribute specific ones.
https://github.com/rails/rails/blob/4-2-stable/guides/source/active_record_querying.md
Example
GroupMember.find_or_create_by_member_id_and_group_id(4, 7)

GroupMember.find_or_create_by(member_id: 4, group_id: 7)

Tried and working. you are using,
<textarea name='Status'> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>
I am using javascript , (don't know about php), use id ="status" in textarea like
<textarea name='Status' id="status"> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>
then make a call to servlet sending the status to backend for updating using whatever strutucre(like MVC in java or anyother) you like, like this in your UI in script tag
<srcipt>
function UpdateStatus(){
//make an ajax call and get status value using the same 'id'
var var1= document.getElementById("status").value;
$.ajax({
type:"GET",//or POST
url:'http://localhost:7080/ajaxforjson/Testajax',
// (or whatever your url is)
data:{data1:var1},
//can send multipledata like {data1:var1,data2:var2,data3:var3
//can use dataType:'text/html' or 'json' if response type expected
success:function(responsedata){
// process on data
alert("got response as "+"'"+responsedata+"'");
}
})
}
</script>
and jsp is like
the servlet will look like: //webservlet("/zcvdzv") is just for url annotation
@WebServlet("/Testajax")
public class Testajax extends HttpServlet {
private static final long serialVersionUID = 1L;
public Testajax() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String data1=request.getParameter("data1");
//do processing on datas pass in other java class to add to DB
// i am adding or concatenate
String data="i Got : "+"'"+data1+"' ";
System.out.println(" data1 : "+data1+"\n data "+data);
response.getWriter().write(data);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}
To print the columns with a specific string, you use the // search pattern. For example, if you are looking for second columns that contains abc:
awk '$2 ~ /abc/'
... and if you want to print only a particular column:
awk '$2 ~ /abc/ { print $3 }'
... and for a particular line number:
awk '$2 ~ /abc/ && FNR == 5 { print $3 }'
You can make virtualenvwrapper use a custom Python binary instead of the one virtualenvwrapper is run with. To do that you need to use VIRTUALENV_PYTHON variable which is utilized by virtualenv:
$ export VIRTUALENV_PYTHON=/usr/bin/python3
$ mkvirtualenv -a myproject myenv
Running virtualenv with interpreter /usr/bin/python3
New python executable in myenv/bin/python3
Also creating executable in myenv/bin/python

Type "help", "copyright", "credits" or "license" for more information.
The traditional way is to have a Makefile
in each of the subdirectories (part1
, part2
, etc.) allowing you to build them independently. Further, have a Makefile
in the root directory of the project which builds everything. The "root" Makefile
would look something like the following:
all:
+$(MAKE) -C part1
+$(MAKE) -C part2
+$(MAKE) -C part3
Since each line in a make target is run in its own shell, there is no need to worry about traversing back up the directory tree or to other directories.
I suggest taking a look at the GNU make manual section 5.7; it is very helpful.
In JSF 2.2 it's possible to use passthrough elements:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:jsf="http://xmlns.jcp.org/jsf">
...
<div jsf:id="id1" />
...
</html>
The requirement is to have at least one attribute in the element using jsf namespace.
hello to everyone just wanted to share my experience with phpMailer , that was working locally (XAMPP) but wasn't working on my hosting provider.
I turned on phpMailer error reporting
$mail->SMTPDebug=2
i got 'Connection refused Error'
I email my host provider for the issue , and he said that he would open the SMTP PORTS and he opened the ports 25,465,587 .
Then i got the following error response "SMTP ERROR: Password command failed:"...."Please log in via your web browser and then try again"...."SMTP Error: Could not authenticate."
So google checks if your are logged in to your account (i was when i ran the script locally through my browser) and then allows you to send mail through the phpMailer script.
To fix that 1:go to your google account -> security 2:Scroll to the Key Icon and choose "2 way verification" and follow the procedure 3:When done go back to the key icon from google account -> security and choose the second option "create app passwords" and follow the procedure to get the password.
Now go to your phpMailer object and change your google password with the password given from the above procedure
you are done .
The code
require_once('class.phpmailer.php');
$phpMailerObj= new PHPMailer();
$phpMailerObj->isSMTP();
$phpMailerObj->SMTPDebug = 0;
$phpMailerObj->Debugoutput = 'html';
$phpMailerObj->Host = 'smtp.gmail.com';
$phpMailerObj->Port = 587;
$phpMailerObj->SMTPSecure = 'tls';
$phpMailerObj->SMTPAuth = true;
$phpMailerObj->Username = "YOUR EMAIL";
$phpMailerObj->Password = "THE NEW PASSWORD FROM GOOGLE ";
$phpMailerObj->setFrom('YOUR EMAIL ADDRESS', 'THE NAME OF THE SENDER',0);
$phpMailerObj->addAddress('RECEIVER EMAIL ADDRESS', 'RECEIVER NAME');
$phpMailerObj->Subject = 'SUBJECT';
$phpMailerObj->Body ='MESSAGE';
if (!phpMailerObj->send()) {
echo "phpMailerObjer Error: " . $phpMailerObj->ErrorInfo;
return 0;
} else {
echo "Message sent!";
return 1;
}
driver.close
and driver.quit
are two different methods for closing the browser session in Selenium WebDriver. Understanding both of them and knowing when to use each method is important in your test execution. Therefore, I have tried to shed some light on both of these methods.
driver.close
- This method closes the browser window on which the focus is set. Despite the familiar name for this method, WebDriver
does not implement the AutoCloseable
interface.
driver.quit
– This method basically calls driver.dispose
a now internal method which in turn closes all of the browser windows and ends the WebDriver session gracefully.
driver.dispose
- As mentioned previously, is an internal method of WebDriver which has been silently dropped according to another answer - Verification needed. This method really doesn't have a use-case in a normal test workflow as either of the previous methods should work for most use cases.
Explanation use case:
You should use driver.quit
whenever you want to end the program. It will close all opened browser windows and terminates the WebDriver session. If you do not use driver.quit
at the end of the program, the WebDriver session will not close properly and files would not be cleared from memory. This may result in memory leak errors.
The above explanation should explain the difference between driver.close
and driver.quit
methods in WebDriver. I hope you find it useful.
The following website has some good tips on selenium testing : Link
Set the check box after loading the modal window. I think you are setting the check box before loading the page.
$('#fModal').modal('show');
$("#estado_cat").attr("checked","checked");
I don't know anything about EF really, but in LINQ to SQL you usually express a LIKE clause using String.Contains:
where entity.Name.Contains("xyz")
translates to
WHERE Name LIKE '%xyz%'
(Use StartsWith
and EndsWith
for other behaviour.)
I'm not entirely sure whether that's helpful, because I don't understand what you mean when you say you're trying to implement LIKE. If I've misunderstood completely, let me know and I'll delete this answer :)
In windows, if Python is installed into the default directory (For me it is):
cd C:\Python27
You then proceed to type
"python.exe "[FULLPATH]\[name].py"
to run your Python script in Command Prompt
-- First Truncate temporary table SQL> TRUNCATE TABLE test_temp1; -- Then Drop temporary table SQL> DROP TABLE test_temp1;
The best way to set/get the value of a textarea is the .val()
, .value
method.
.text()
internally uses the .textContent
(or .innerText
for IE) method to get the contents of a <textarea>
. The following test cases illustrate how text()
and .val()
relate to each other:
var t = '<textarea>';
console.log($(t).text('test').val()); // Prints test
console.log($(t).val('too').text('test').val()); // Prints too
console.log($(t).val('too').text()); // Prints nothing
console.log($(t).text('test').val('too').val()); // Prints too
console.log($(t).text('test').val('too').text()); // Prints test
The value
property, used by .val()
always shows the current visible value, whereas text()
's return value can be wrong.
This is a variation on the answers already provided, but should be better performing because it doesn't require ORDER BY, COUNT or MIN/MAX. The only disadvantage with this approach is that you have to create a temp table to hold all the Ids (the assumption is that you have gaps in your list of CustomerIDs).
That said, I agree with @Mark Powell though that, generally speaking, a set based approach should still be better.
DECLARE @tmp table (Id INT IDENTITY(1,1) PRIMARY KEY NOT NULL, CustomerID INT NOT NULL)
DECLARE @CustomerId INT
DECLARE @Id INT = 0
INSERT INTO @tmp SELECT CustomerId FROM Sales.Customer
WHILE (1=1)
BEGIN
SELECT @CustomerId = CustomerId, @Id = Id
FROM @tmp
WHERE Id = @Id + 1
IF @@rowcount = 0 BREAK;
-- call your sproc
EXEC dbo.YOURSPROC @CustomerId;
END
Here is the my solution that I prefer when using stored procedures. Custom mysql function for check the table exists in current database.
delimiter $$
CREATE FUNCTION TABLE_EXISTS(_table_name VARCHAR(45))
RETURNS BOOLEAN
DETERMINISTIC READS SQL DATA
BEGIN
DECLARE _exists TINYINT(1) DEFAULT 0;
SELECT COUNT(*) INTO _exists
FROM information_schema.tables
WHERE table_schema = DATABASE()
AND table_name = _table_name;
RETURN _exists;
END$$
SELECT TABLE_EXISTS('you_table_name') as _exists
Try swich fetchType from LAZY to EAGER
...
@OneToMany(fetch=FetchType.EAGER)
private Set<NodeValue> nodeValues;

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

Other answers have focused more on the multithreading vs multiprocessing aspect, but in python Global Interpreter Lock (GIL) has to be taken into account. When more number (say k) of threads are created, generally they will not increase the performance by k times, as it will still be running as a single threaded application. GIL is a global lock which locks everything out and allows only single thread execution utilizing only a single core. The performance does increase in places where C extensions like numpy, Network, I/O are being used, where a lot of background work is done and GIL is released.
So when threading is used, there is only a single operating system level thread while python creates pseudo-threads which are completely managed by threading itself but are essentially running as a single process. Preemption takes place between these pseudo threads. If the CPU runs at maximum capacity, you may want to switch to multiprocessing.
Now in case of self-contained instances of execution, you can instead opt for pool. But in case of overlapping data, where you may want processes communicating you should use multiprocessing.Process
.
See this:
Align ImageView with EditText horizontally
It seems that the background image of EditText has some transparent pixels which also add padding.
A solution is to change the default background of EditText to something else (or nothing, but no background for a EditText is probably not acceptable). That's can be made setting android:background XML attribute.
android:background="@drawable/myEditBackground"
We use the logging module for this.
For example:
import logging
class SomeTest( unittest.TestCase ):
def testSomething( self ):
log= logging.getLogger( "SomeTest.testSomething" )
log.debug( "this= %r", self.this )
log.debug( "that= %r", self.that )
# etc.
self.assertEquals( 3.14, pi )
if __name__ == "__main__":
logging.basicConfig( stream=sys.stderr )
logging.getLogger( "SomeTest.testSomething" ).setLevel( logging.DEBUG )
unittest.main()
That allows us to turn on debugging for specific tests which we know are failing and for which we want additional debugging information.
My preferred method, however, isn't to spend a lot of time on debugging, but spend it writing more fine-grained tests to expose the problem.
I have pieced together the following that is hopefully simpler and cleaner than some of the existing answers and uses only the AWS CLI and no additional tools.
This code example shows how to get the value of tag 'myTag' for the current EC2 instance:
Using describe-tags:
export AWS_DEFAULT_REGION=us-east-1
instance_id=$(curl -s http://169.254.169.254/latest/meta-data/instance-id)
aws ec2 describe-tags \
--filters "Name=resource-id,Values=$instance_id" 'Name=key,Values=myTag' \
--query 'Tags[].Value' --output text
Or, alternatively, using describe-instances:
aws ec2 describe-instances --instance-id $instance_id \
--query 'Reservations[].Instances[].Tags[?Key==`myTag`].Value' --output text
Why not using the method toISOString()
with slice
or simply toLocaleDateString()
?
Check here:
const d = new Date() // today, now
console.log(d.toISOString().slice(0, 10)) // YYYY-MM-DD
console.log(d.toLocaleDateString('en-US')) // M/D/YYYY
console.log(d.toLocaleDateString('de-DE')) // D.M.YYYY
console.log(d.toLocaleDateString('pt-PT')) // DD/MM/YYYY

We also had this problem when upgrading our system to Revive. After turning of GZIP we found the problem still persisted. Upon further investigation we found the file permissions where not correct after the upgrade. A simple recursive chmod did the trick.
There are some good solutions above, and mine is just a combination of two (I came here looking for a solution).
@Sarvar Nishonboyev's solution is good because it maintains the creation of the form input label and help-block for error messages.
I went with:
<?php
use yii\helpers\ArrayHelper;
use app\models\Product;
?>
<?=
$form->field($model, 'parent_id')
->dropDownList(
ArrayHelper::map(Product::find()->asArray()->all(), 'parent_id', 'name')
)
?>
Again, full credit to: @Sarvar Nishonboyev's and @ippi

Example solution for adding the library to your PYTHONPATH.
Add the following line into your ~/.bashrc or just run it directly:
export PYTHONPATH="$PYTHONPATH:$HOME/.python"
Then link your required library into your ~/.python folder, e.g.
ln -s /home/user/work/project/foo ~/.python/
Handle the Worksheet_Change
event or the Workbook_SheetChange
event.
The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.
DSM's and Tadeck's answers answer your question directly.
In my scripts I often use the convenient dict.pop()
to deal with optional, and additional arguments. Here's an example of a simple print()
wrapper:
def my_print(*args, **kwargs):
prefix = kwargs.pop('prefix', '')
print(prefix, *args, **kwargs)
Then:
>>> my_print('eggs')

As you can see, if prefix
is not contained in kwargs
, then the default ''
(empty string) is being stored in the local prefix
variable. If it is given, then its value is being used.
This is generally a compact and readable recipe for writing wrappers for any kind of function: Always just pass-through arguments you don't understand, and don't even know if they exist. If you always pass through *args
and **kwargs
you make your code slower, and requires a bit more typing, but if interfaces of the called function (in this case print
) changes, you don't need to change your code. This approach reduces development time while supporting all interface changes.
The usual way to use assertRaises
is to call a function:
self.assertRaises(TypeError, test_function, args)
to test that the function call test_function(args) raises a TypeError.
The problem with self.testListNone[:1]
is that Python evaluates the expression immediately, before the assertRaises
method is called. The whole reason why test_function
and args
is passed as separate arguments to self.assertRaises
is to allow assertRaises
to call test_function(args)
from within a try...except
block, allowing assertRaises
to catch the exception.
Since you've defined self.testListNone = None
, and you need a function to call, you might use operator.itemgetter like this:
import operator
self.assertRaises(TypeError, operator.itemgetter, (self.testListNone,slice(None,1)))
since
operator.itemgetter(self.testListNone,slice(None,1))
is a long-winded way of saying self.testListNone[:1]
, but which separates the function (operator.itemgetter
) from the arguments.
Lodash has a nice _.cloneDeep(value) method:
var objects = [{ 'a': 1 }, { 'b': 2 }];
var deep = _.cloneDeep(objects);
console.log(deep[0] === objects[0]);
// => false
No, there isn't such constant.
I don't think you need/want the timeout.
onhover (hover) would be defined as the time period while "over" something. IMHO
onmouseover = start...
onmouseout = ...end
For the record I've done some stuff with this to "fake" the hover event in IE6. It was rather expensive and in the end I ditched it in favor of performance.

99.9% likely that you have corrupted memory (over- or under-flowed a buffer, wrote to a pointer after it was freed, called free twice on the same pointer, etc.)
Run your code under Valgrind to see where your program did something incorrect.
I just tried SMTPop and it worked.
smtpop.dll
reference to my C# .NET projectWrote the following code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SmtPop;
namespace SMT_POP3 {
class Program {
static void Main(string[] args) {
SmtPop.POP3Client pop = new SmtPop.POP3Client();
pop.Open("<hostURL>", 110, "<username>", "<password>");
// Get message list from POP server
SmtPop.POPMessageId[] messages = pop.GetMailList();
if (messages != null) {
// Walk attachment list
foreach(SmtPop.POPMessageId id in messages) {
SmtPop.POPReader reader= pop.GetMailReader(id);
SmtPop.MimeMessage msg = new SmtPop.MimeMessage();
// Read message
msg.Read(reader);
if (msg.AddressFrom != null) {
String from= msg.AddressFrom[0].Name;
Console.WriteLine("from: " + from);
}
if (msg.Subject != null) {
String subject = msg.Subject;
Console.WriteLine("subject: "+ subject);
}
if (msg.Body != null) {
String body = msg.Body;
Console.WriteLine("body: " + body);

SmtPop.MimeAttachment attach = msg.Attachments[0];
if (attach.Filename == "data") {
// Read data from attachment

I think this is what you want:
JavaScriptSerializer JSS = new JavaScriptSerializer();
T obj = JSS.Deserialize<T>(String);
With me mostly it happens when I push changes to the wrong branch and realize later. And following works in most of the time.
git revert commit-hash
git push
git checkout my-other-branch
git revert revert-commit-hash
git push
Try doing this:
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force
You can use GroupBy
with anonymous type, and then get First
:
list.GroupBy(e => new {
empLoc = e.empLoc,
empPL = e.empPL,
empShift = e.empShift
})
.Select(g => g.First());
Your selector won't select the input field, and if it did it would return a jQuery object. Try this:
$('#test2').is(':checked');
Double toBeTruncated = new Double("2.25");
Double truncatedDouble = new BigDecimal(toBeTruncated).setScale(1, BigDecimal.ROUND_HALF_UP).doubleValue();
it will return 2.3

If you are getting json from database, put
mysqli_set_charset($con, "utf8");

You can do it using string.indexOf("{item}")
. If the result is greater than -1 {item}
is in the string
To ignore some files in a directory, you have to do this in the correct order:
For example, ignore everything in folder "application" except index.php and folder "config" pay attention to the order.
You must negate want you want first.
FAILS
application/*
!application/config/*
!application/index.php
WORKS
!application/config/*
!application/index.php
application/*
In addition to the suggestion by Konrad here, I'd like to suggest jupyter themes, which seems to have more options, such as line-height, font size, cell width etc.
Command line usage:
jt [-h] [-l] [-t THEME] [-f MONOFONT] [-fs MONOSIZE] [-nf NBFONT]
[-nfs NBFONTSIZE] [-tf TCFONT] [-tfs TCFONTSIZE] [-dfs DFFONTSIZE]
[-m MARGINS] [-cursw CURSORWIDTH] [-cursc CURSORCOLOR] [-vim]
[-cellw CELLWIDTH] [-lineh LINEHEIGHT] [-altp] [-P] [-T] [-N]
[-r] [-dfonts]
1. Approach:
RMI uses an object-oriented paradigm where the user needs to know the object and the method of the object he needs to invoke.
RPC doesn't deal with objects. Rather, it calls specific subroutines that are already established.
2. Working:
With RPC, you get a procedure call that looks pretty much like a local call. RPC handles the complexities involved with passing the call from local to the remote computer.
RMI does the very same thing, but RMI passes a reference to the object and the method that is being called.
RMI = RPC + Object-orientation
3. Better one:
RMI is a better approach compared to RPC, especially with larger programs as it provides a cleaner code that is easier to identify if something goes wrong.
4. System Examples:
RPC Systems: SUN RPC, DCE RPC
RMI Systems: Java RMI, CORBA, Microsoft DCOM/COM+, SOAP(Simple Object Access Protocol)
Try this, if enter key was pressed you can capture it like this for example, I developed an answer the other day html button specify selected, see if this helps.
Specify the forms name as for example yourFormName
then you should be able to submit the form without having focus on the form.
document.onkeypress = keyPress;
function keyPress(e){
var x = e || window.event;
var key = (x.keyCode || x.which);
if(key == 13 || key == 3){
// myFunc1();
document.yourFormName.submit();
}
}
add this in your code block, or even click of your button
$('input:checkbox').attr('checked',false);
The cited answer was wrong. You had to change
csvContent += index < infoArray.length ? dataString+ "\n" : dataString;
to
csvContent += dataString + "\n";
As to why the cited answer was wrong (funny it has been accepted!): index
, the second parameter of the forEach
callback function, is the index in the looped-upon array, and it makes no sense to compare this to the size of infoArray
, which is an item of said array (which happens to be an array too).
Six years have passed now since I wrote this answer. Many things have changed, including browsers. The following was part of the answer:
START of aged part
BTW, the cited code is suboptimal. You should avoid to repeatedly append to a string. You should append to an array instead, and do an array.join("\n") at the end. Like this:
var lineArray = [];
data.forEach(function (infoArray, index) {
var line = infoArray.join(",");
lineArray.push(index == 0 ? "data:text/csv;charset=utf-8," + line : line);
});
var csvContent = lineArray.join("\n");
END of aged part
(Keep in mind that the CSV case is a bit different from generic string concatenation, since for every string you also have to add the separator.)
Anyway, the above seems not to be true anymore, at least not for Chrome and Firefox (it seems to still be true for Safari, though).
To put an end to uncertainty, I wrote a jsPerf test that tests whether, in order to concatenate strings in a comma-separated way, it's faster to push them onto an array and join the array, or to concatenate them first with the comma, and then directly with the result string using the += operator.
Please follow the link and run the test, so that we have enough data to be able to talk about facts instead of opinions.
You can open a new powershell window under a specified user credential like this:
start powershell -credential ""
Just adding to the answers already given, the solution using the string "nunique"
seems much faster, tested here on ~21M rows dataframe, then grouped to ~2M
%time _=g.agg({"id": lambda x: x.nunique()})
CPU times: user 3min 3s, sys: 2.94 s, total: 3min 6s
Wall time: 3min 20s
%time _=g.agg({"id": pd.Series.nunique})
CPU times: user 3min 2s, sys: 2.44 s, total: 3min 4s
Wall time: 3min 18s
%time _=g.agg({"id": "nunique"})
CPU times: user 14 s, sys: 4.76 s, total: 18.8 s
Wall time: 24.4 s
To make a dropdown list you need two properties:
In your case you only have a list of string which cannot be exploited to create a usable drop down list.
While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:
@model List<string>
@Html.DropDownList(
"Foo",
new SelectList(
Model.Select(x => new { Value = x, Text = x }),
"Value",
"Text"
)
)
where Foo
will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:
<select name="Foo" id="Foo">
<option value="item 1">item 1</option>
<option value="item 2">item 2</option>
<option value="item 3">item 3</option>
...
</select>
This being said a far better view model for a drop down list is the following:
public class MyListModel
{
public string SelectedItemId { get; set; }
public IEnumerable<SelectListItem> Items { get; set; }
}
and then:
@model MyListModel
@Html.DropDownListFor(
x => x.SelectedItemId,
new SelectList(Model.Items, "Value", "Text")
)
and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId
property of this view model to the corresponding Value
of some element in the Items
collection.
You can expend the following function in order to pull out more parameters from the DB before the insert:
--
-- insert_employee (Function)
--
CREATE OR REPLACE FUNCTION insert_employee(p_emp_id in number, p_emp_name in varchar2, p_emp_address in varchar2, p_emp_state in varchar2, p_emp_position in varchar2, p_emp_manager in varchar2)
RETURN VARCHAR2 AS
p_state_id varchar2(30) := '';
BEGIN
select state_id
into p_state_id
from states where lower(emp_state) = state_name;
INSERT INTO Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager) VALUES
(p_emp_id, p_emp_name, p_emp_address, p_state_id, p_emp_position, p_emp_manager);
return 'SUCCESS';
EXCEPTION
WHEN others THEN
RETURN 'FAIL';
END;

I think the best and cleanest way would be to get a custom download of bootstrap.
http://getbootstrap.com/customize/
You can then change the font-defaults in the Typography (in that link). This then gives you a .Less file that you can make further changes to defaults with later.
There's no easy way to find out the memory size of a python object. One of the problems you may find is that Python objects - like lists and dicts - may have references to other python objects (in this case, what would your size be? The size containing the size of each object or not?). There are some pointers overhead and internal structures related to object types and garbage collection. Finally, some python objects have non-obvious behaviors. For instance, lists reserve space for more objects than they have, most of the time; dicts are even more complicated since they can operate in different ways (they have a different implementation for small number of keys and sometimes they over allocate entries).
There is a big chunk of code (and an updated big chunk of code) out there to try to best approximate the size of a python object in memory.
You may also want to check some old description about PyObject (the internal C struct that represents virtually all python objects).
edit 2018: This is outdated, js and typescript now have for..of loops.
http://www.typescriptlang.org/docs/handbook/iterators-and-generators.html
The book "TypeScript Revealed" says
"You can iterate through the items in an array by using either for or for..in loops as demonstrated here:
// standard for loop
for (var i = 0; i < actors.length; i++)
{
console.log(actors[i]);
}
// for..in loop
for (var actor in actors)
{
console.log(actor);
}
"
Turns out, the second loop does not pass the actors in the loop. So would say this is plain wrong. Sadly it is as above, loops are untouched by typescript.
map and forEach often help me and are due to typescripts enhancements on function definitions more approachable, lke at the very moment:
this.notes = arr.map(state => new Note(state));
My wish list to TypeScript;
window.location.reload() or just location.reload()
You can try this:
pushd ../
maven install [...]
popd
I know that you don't want to hear that, but: I consider the best practice is the most readable in this case. As long as the loop is not counting from here to the moon, the performance-gain will not be uhge enough.
Under HTML5 you are be able to do this:
document.getElementById('test').selectedOptions[0].text
MDN's documentation at https://developer.mozilla.org/en-US/docs/Web/API/HTMLSelectElement/selectedOptions indicates full cross-browser support (as of at least December 2017), including Chrome, Firefox, Edge and mobile browsers, but excluding Internet Explorer.
Using jQuery's .is( ":focus" )
$(".status").on("click","textarea",function(){
if ($(this).is( ":focus" )) {
// fire this step
}else{
$(this).focus();
// fire this step
}
'Is not possible!'
Oh yes it is ....

function unloadJS(scriptName) {

var jsArray = new Array();
jsArray = document.getElementsByTagName('script');
for (i = 0; i < jsArray.length; i++){
if (jsArray[i].id){
unloadJS(jsArray[i].id)
}else{
jsArray[i].parentNode.removeChild(jsArray[i]);
}
}
}
There are multiple classes that are grouped together as "numeric" classes, the 2 most common of which are double (for double precision floating point numbers) and integer. R will automatically convert between the numeric classes when needed, so for the most part it does not matter to the casual user whether the number 3 is currently stored as an integer or as a double. Most math is done using double precision, so that is often the default storage.
Sometimes you may want to specifically store a vector as integers if you know that they will never be converted to doubles (used as ID values or indexing) since integers require less storage space. But if they are going to be used in any math that will convert them to double, then it will probably be quickest to just store them as doubles to begin with.
I had the ValueError: zlib is required unless explicitly disabled using --disable-zlib

So I would try to update tools before anything else.
That can be done using:

another example: google map api vs google direction api web service, while the former serves (delivers) javascript file to the site (which can then be used as an api to make new functions) , the later is a Rest web service delivering data (in json or xml format), which can be processed (but not used in an api sense).
You need one project per language. I'm quite confident I saw a tool that merged assemblies, if you find that tool you should be good to go. If you need to use both languages in the same class, you should be able to write half of it in say VB.net and then write the rest in C# by inheriting the VB.net class.
Using the Signum.Utilities library from SignumFramework (which you can use stand-alone), you can get it nicely and without dealing with the registry by yourself:

//v3.0 SP2
//v3.5 SP1

Here's a helpful article on long polling (long-held HTTP request) using jQuery. A code snippet derived from this article:
(function poll() {
setTimeout(function() {
$.ajax({
url: "/server/api/function",
type: "GET",
success: function(data) {
console.log("polling");
},
dataType: "json",
complete: poll,
timeout: 2000
})
}, 5000);
})();
This will make the next request only after the ajax request has completed.
A variation on the above that will execute immediately the first time it is called before honouring the wait/timeout interval.
(function poll() {
$.ajax({
url: "/server/api/function",
type: "GET",
success: function(data) {
console.log("polling");
},
dataType: "json",
complete: setTimeout(function() {poll()}, 5000),
timeout: 2000
})
})();
Another way that works with the YAML parser used in Jekyll:
title: My Life: A Memoir
Colons not followed by spaces don't seem to bother Jekyll's YAML parser, on the other hand. Neither do dashes.
It is very easy to achieve with built in method SelectAll
Simply cou can write this:
txtTextBox.Focus();
txtTextBox.SelectAll();
And everything in textBox will be selected :)
have at look at the static methods DateTime.Parse()
and DateTime.TryParse()
. They will allow you to pass in your date string and a format string, and get a DateTime object in return.
you can try to add this

to the configure options
CREATE SCHEMA exe AUTHORIZATION [dbo]

Here is a sample showing an easy way to do it. The script is:
$(function() {
var _t = $("#container").scrollTop();
$("#container").scroll(function() {
var _n = $("#container").scrollTop();
if (_n > _t) {
$("#target").text("Down");
} else {
$("#target").text("Up");
}
_t = _n;
});
});
The #container
is your div id
. The #target
is just to see it working. Change to what you want when up or when down.
EDIT
The OP didn't say before, but since he's using a div with overflow: hidden
, scrolling doesn't occur, then the script to detect the scroll is the least of it. Well, how to detect something that does not happen?!
So, the OP himself posted the link with what he wants, so why not use that library? http://cdn.jquerytools.org/1.2.5/full/jquery.tools.min.js.
The call is just:
$(function() {
$(".scrollable").scrollable({ vertical: true, mousewheel: true });
});
If you add this to your web.config transformation file, you can also set certain publish options to have debugging enabled or disabled:
<system.web>
<customErrors mode="Off" defaultRedirect="~/Error.aspx" xdt:Transform="Replace"/>
</system.web>
Initializing a vector having struct, class or Union can be done this way
std::vector<SomeStruct> someStructVect(length);
memset(someStructVect.data(), 0, sizeof(SomeStruct)*length);
These are the preferred methods:
var item = Items.SingleOrDefault(x => x.Id == 123);
Or
var item = Items.Single(x => x.Id == 123);
maybe this can help..

As mentioned earlier, you can indicate that a variable or method is private by prefixing it with an underscore. If you don't feel like this is enough, you can always use the property
decorator. Here's an example:
class Foo:
def __init__(self, bar):
self._bar = bar
@property
def bar(self):
"""Getter for '_bar'."""
return self._bar
This way, someone or something that references bar
is actually referencing the return value of the bar
function rather than the variable itself, and therefore it can be accessed but not changed. However, if someone really wanted to, they could simply use _bar
and assign a new value to it. There is no surefire way to prevent someone from accessing variables and methods that you wish to hide, as has been said repeatedly. However, using property
is the clearest message you can send that a variable is not to be edited. property
can also be used for more complex getter/setter/deleter access paths, as explained here: https://docs.python.org/3/library/functions.html#property
Simply use list property count\
i = ['apple','red','apple','red','red','pear']
d = {x:i.count(x) for x in i}
print d
output :
{'pear': 1, 'apple': 2, 'red': 3}
Define Principal
as a dependency in your controller method and spring will inject the current authenticated user in your method at invocation.
For anyone else who stumbles on this make sure you're not attempting to modify the class rather than the instance! (unless you've declared the variable as static)
eg.
MyClass.variable = 'Foo' // WRONG! - Instance member 'variable' cannot be used on type 'MyClass'
instanceOfMyClass.variable = 'Foo' // Right!
In case you want to kill not all java processes but specif jars running. It will work for multiple jars as well.
