You can add the src
folder to build path by:
- Select Java perspective.
- Right click on
src
folder. - Select Build Path > Use a source folder.
And you are done. Hope this help.
EDIT: Refer to the Eclipse documentation
To expand on Charles Duffy's answer, Nginx uses the daemon off
directive to run in the foreground. If it's inconvenient to put this in the configuration file, we can specify it directly on the command line. This makes it easy to run in debug mode (foreground) and directly switch to running in production mode (background) by changing command line args.
To run in foreground:
nginx -g 'daemon off;'
To run in background:
nginx
Bootstrap 4
Use the data-parent=""
attribute on the collapse element (instead of the trigger element)
<div id="accordion">
<div class="card">
<div class="card-header">
<h5>
<button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne">
Collapsible #1 trigger
</button>
</h5>
</div>
<div id="collapseOne" class="collapse show" data-parent="#accordion">
<div class="card-body">
Collapsible #1 element
</div>
</div>
</div>
... (more cards/collapsibles inside #accordion parent)
</div>
Bootstrap 3
See this issue on GitHub: https://github.com/twbs/bootstrap/issues/10966
There is a "bug" that makes the accordion dependent on the .panel
class when using the data-parent
attribute. To workaround it, you can wrap each accordion group in a 'panel' div..
<div class="accordion" id="myAccordion">
<div class="panel">
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#collapsible-1" data-parent="#myAccordion">Question 1?</button>
<div id="collapsible-1" class="collapse">
..
</div>
</div>
<div class="panel">
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#collapsible-2" data-parent="#myAccordion">Question 2?</button>
<div id="collapsible-2" class="collapse">
..
</div>
</div>
<div class="panel">
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#collapsible-3" data-parent="#myAccordion">Question 3?</button>
<div id="collapsible-3" class="collapse">
...
</div>
</div>
</div>
Edit
As mentioned in the comments, each section doesn't have to be a .panel
. However...
.panel
must be a direct child of the element used as data-parent=
data-toggle=
) must be a direct child of the .panel
(http://www.bootply.com/AbiRW7BdD6#)if you're on windows, make sure you 'unblock' the lombok.jar before you install it. if you don't do this, it will install but it wont work.
You can use max-height
in an inline style
attribute, as below:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
To use scrolling with content that overflows a given max-height
, you can alternatively try the following:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>
To restrict the height to a fixed value you can use something like this.
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
Specify the same value for both max-height
and min-height
(either in pixels or in points – as long as it’s consistent).
You can also put the same styles in css class in a stylesheet (or a style
tag as shown below) and then include the same in your tag. See below:
Style Code:
.fixed-panel {
min-height: 10;
max-height: 10;
overflow-y: scroll;
}
Apply Style :
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>
Hope this helps with your need.
VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.
EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.
Although this answer is a bit verbose it does allow you to create a single commit branch by doing a single merge with another branch. (No rebasing/squashing/merging individual commits).
Since we don't care about the in-between commits we can use a simple solution:
# Merge and resolve conflicts
git merge origin/master
# Soft reset and create a HEAD with the version you want
git reset --soft origin/master
git commit -m "Commit message"
git push origin your-branch -f
... then to remove the history...
# Get the most up-to-date master
git checkout master
git reset --hard
# Create a temporary branch
git checkout -b temp-branch
# Retrieve the diff between master and your-branch and commit with a single commit
git checkout origin/your-branch
git commit -m "Feature commit"
# Force push to the feature branch
git push origin temp-branch:your-branch -f
# Clean up
git checkout your-branch
git branch -D temp-branch
This can all be put into a bash function with 3 params like so squashall --their master --mine your-branch --msg "Feature commit"
and it will work as long as you have the correct version of files locally.
It is worth to note that it's possible to add Q expressions.
For example:
from django.db.models import Q
query = Q(first_name='mark')
query.add(Q(email='[email protected]'), Q.OR)
query.add(Q(last_name='doe'), Q.AND)
queryset = User.objects.filter(query)
This ends up with a query like :
(first_name = 'mark' or email = '[email protected]') and last_name = 'doe'
This way there is no need to deal with or operators, reduce's etc.
You can use inWaiting()
to get the amount of bytes available at the input queue.
Then you can use read()
to read the bytes, something like that:
While True:
bytesToRead = ser.inWaiting()
ser.read(bytesToRead)
Why not to use readline()
at this case from Docs:
Read a line which is terminated with end-of-line (eol) character (\n by default) or until timeout.
You are waiting for the timeout at each reading since it waits for eol. the serial input Q remains the same it just a lot of time to get to the "end" of the buffer, To understand it better: you are writing to the input Q like a race car, and reading like an old car :)
For printing the Name column
df['Name']
extend class to AppCompatActivity
instead of Activity
I just stumbled upon this question and here is an update for Swift 3 and iOS 10:
let testUIBarButtonItem = UIBarButtonItem(image: UIImage(named: "test.png"), style: .plain, target: self, action: nil)
self.navigationItem.rightBarButtonItem = testUIBarButtonItem
It is definitely much faster than creating the UIButton with all the properties and then subsequently adding the customView to the UIBarButtonItem.
And if you want to change the color of the image from the default blue to e.g. white, you can always change the tint color:
test.tintColor = UIColor.white()
PS You should obviously change the selector etc. for your app :)
# This code works fine in QtSpim simulator
.data
buffer: .space 20
str1: .asciiz "Enter string"
str2: .asciiz "You wrote:\n"
.text
main:
la $a0, str1 # Load and print string asking for string
li $v0, 4
syscall
li $v0, 8 # take in input
la $a0, buffer # load byte space into address
li $a1, 20 # allot the byte space for string
move $t0, $a0 # save string to t0
syscall
la $a0, str2 # load and print "you wrote" string
li $v0, 4
syscall
la $a0, buffer # reload byte space to primary address
move $a0, $t0 # primary address = t0 address (load pointer)
li $v0, 4 # print string
syscall
li $v0, 10 # end program
syscall
Two ways come to mind:
Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that
Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.
Set display:inline-block
and then adjust your margins.
fiddle here: http://jsfiddle.net/Q2MrC/
For example, if you want to make the color of "text" green, just type:
<font color='green'>text</font>
strtotime( "+1 month", strtotime( $time ) );
this returns a timestamp that can be used with the date function
You can use white-space: nowrap;
to define this behaviour:
// HTML:
.nowrap {_x000D_
white-space: nowrap ;_x000D_
}
_x000D_
<p>_x000D_
<span class="nowrap">How do I wrap this line of text</span>_x000D_
<span class="nowrap">- asked by Peter 2 days ago</span>_x000D_
</p>
_x000D_
// CSS:
.nowrap {
white-space: nowrap ;
}
You wont be able to get python to tell you where the JSON is incorrect. You will need to use a linter online somewhere like this
This will show you error in the JSON you are trying to decode.
From The Definitive Guide to Django: Web Development Done Right:
If you’ve used Python before, you may be wondering why we’re running
python manage.py shell
instead of justpython
. Both commands will start the interactive interpreter, but themanage.py shell
command has one key difference: before starting the interpreter, it tells Django which settings file to use.
Use Case: Many parts of Django, including the template system, rely on your settings, and you won’t be able to use them unless the framework knows which settings to use.
If you’re curious, here’s how it works behind the scenes. Django looks for an environment variable called
DJANGO_SETTINGS_MODULE
, which should be set to the import path of your settings.py. For example,DJANGO_SETTINGS_MODULE
might be set to'mysite.settings'
, assuming mysite is on your Python path.When you run
python manage.py shell
, the command takes care of settingDJANGO_SETTINGS_MODULE
for you.**

As you can see from the screenshot below, the output is colored and the error message comes in the used language.
you must put at least a capture ()
in the pattern to match, and correct pattern like this:
String[] words = {"{apf","hum_","dkoe","12f"};
for(String s:words)
{
if(s.matches("(^[a-z]+$)"))
{
System.out.println(s);
}
}
Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.
Example
<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

I believe that the easiest way is to create an alias for the command sh
, e.g.
adb shell

cd /system/bin
cat sh > su && chmod 4775 su
Tested on Android Emulator 3.0 and higher.
fork, exec, and wait should work, if you're not really looking for a Objective-C specific way. fork
creates a copy of the currently running program, exec
replaces the currently running program with a new one, and wait
waits for the subprocess to exit. For example (without any error checking):
#include <stdlib.h>
#include <unistd.h>
pid_t p = fork();
if (p == 0) {
/* fork returns 0 in the child process. */
execl("/other/program/to/run", "/other/program/to/run", "foo", NULL);
} else {
/* fork returns the child's PID in the parent. */
int status;
wait(&status);
/* The child has exited, and status contains the way it exited. */
}
/* The child has run and exited by the time execution gets to here. */
There's also system, which runs the command as if you typed it from the shell's command line. It's simpler, but you have less control over the situation.
I'm assuming you're working on a Mac application, so the links are to Apple's documentation for these functions, but they're all POSIX
, so you should be to use them on any POSIX-compliant system.
That is a constraint on the generic parameter T
. It must be a class
(reference type) and must have a public parameter-less default constructor.
That means T
can't be an int
, float
, double
, DateTime
or any other struct
(value type).
It could be a string
, or any other custom reference type, as long as it has a default or parameter-less constructor.
Usefull script which you can delete all data in all tables of a database , replace tt with you databse name :
declare @tablename nvarchar(100)
declare c1 cursor for
SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_CATALOG='tt' AND TABLE_TYPE='BASE TABLE'
open c1
fetch next from c1 into @tablename
while @@FETCH_STATUS = 0
begin
print @t1
exec('alter table ' + @tablename + ' nocheck constraint all')
exec('delete from ' + @tablename)
exec ('alter table ' + @tablename + ' check constraint all')
fetch next from c1 into @tablename
end
close c1
DEALLOCATE c1
Below code is most suitable way to verify a text on page. You can use any one out of 8 locators as per your convenience.

In my case with Ubuntu 14.04.3 and Apache 2.4.7, the problem was that I copied site1.conf to make site2.conf available, and by copying, something happend and I could not a2ensite site2.conf with the error described in thread.
The solution for me, was to rename site2.conf to site2 and then again rename site2 to site2.conf. After that I was able to a2ensite site2.conf.
If you use the track by
option, the value
attribute is correctly written, e.g.:
<div ng-init="a = [{label: 'one', value: 15}, {label: 'two', value: 20}]">
<select ng-model="foo" ng-options="x for x in a track by x.value"/>
</div>
produces:
<select>
<option value="" selected="selected"></option>
<option value="15">one</option>
<option value="20">two</option>
</select>
In my case the trouble was I didn't put the components that contain the datasource in the declarations of main module.

There's a simple one-liner for this:
String target = myData.replaceAll("[^']*(?:'(.*?)')?.*", "$1");
By making the matching group optional, this also caters for quotes not being found by returning a blank in that case.
See live demo.
You can simply write :
class A(object):
def __init__(self):
print "Initialiser A was called"
class B(A):
def __init__(self):
A.__init__(self)
# A.__init__(self,<parameters>) if you want to call with parameters
print "Initialiser B was called"
class C(B):
def __init__(self):
# A.__init__(self) # if you want to call most super class...
B.__init__(self)
print "Initialiser C was called"
Per Truth value testing, 'None' directly tests as FALSE, so the simplest expression will suffice:
if not foo:
What are you using to compile this? If there's an undefined reference error, usually it's because the .o file (which gets created from the .cpp file) doesn't exist and your compiler/build system is not able to link it.
Also, in your card.cpp, the function should be Card::Card()
instead of void Card
. The Card::
is scoping; it means that your Card()
function is a member of the Card class (which it obviously is, since it's the constructor for that class). Without this, void Card is just a free function. Similarly,
void Card(Card::Rank rank, Card::Suit suit)
should be
Card::Card(Card::Rank rank, Card::Suit suit)
Also, in deck.cpp, you are saying #include "Deck.h"
even though you referred to it as deck.h. The includes are case sensitive.
I find that there are 3 package-based solutions to solve the problem. They are pyenchant, wordnet and corpus(self-defined or from ntlk). Pyenchant couldn't installed easily in win64 with py3. Wordnet doesn't work very well because it's corpus isn't complete. So for me, I choose the solution answered by @Sadik, and use 'set(words.words())' to speed up.
First:
pip3 install nltk
python3
import nltk
nltk.download('words')
Then:
from nltk.corpus import words
setofwords = set(words.words())
print("hello" in setofwords)
>>True
The simple solution would be to use a ItemListener
. When the state changes, you would simply check the currently selected item and set the text accordingly
import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestComboBox06 {
public static void main(String[] args) {
new TestComboBox06();
}
public TestComboBox06() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException ex) {
} catch (InstantiationException ex) {
} catch (IllegalAccessException ex) {
} catch (UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JComboBox cb;
private JTextField field;
public TestPane() {
cb = new JComboBox(new String[]{"Item 1", "Item 2"});
field = new JTextField(12);
add(cb);
add(field);
cb.setSelectedItem(null);
cb.addItemListener(new ItemListener() {
@Override
public void itemStateChanged(ItemEvent e) {
Object item = cb.getSelectedItem();
if ("Item 1".equals(item)) {
field.setText("20");
} else if ("Item 2".equals(item)) {
field.setText("30");
}
}
});
}
}
}
A better solution would be to create a custom object that represents the value to be displayed and the value associated with it...
Updated
Now I no longer have a 10 month chewing on my ankles, I updated the example to use a ListCellRenderer
which is a more correct approach then been lazy and overriding toString

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.
mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )
mysql $link
generally means, the resource object of the established mysqli connection to query the database.
So there are two ways of solving this problem
mysqli_query();
$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql");
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));
Or, Using mysql_query()
(This is now obselete)
$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());
As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .
I was getting errors in the console as well as the compiler and IDE when using the SimpleChanges
type in the function signature. To prevent the errors, use the any
keyword in the signature instead.
ngOnChanges(changes: any) {
console.log(changes.myInput.currentValue);
}
EDIT:
As Jon pointed out below, you can use the SimpleChanges
signature when using bracket notation rather than dot notation.
ngOnChanges(changes: SimpleChanges) {
console.log(changes['myInput'].currentValue);
}
NumPy is not just more efficient; it is also more convenient. You get a lot of vector and matrix operations for free, which sometimes allow one to avoid unnecessary work. And they are also efficiently implemented.
For example, you could read your cube directly from a file into an array:
x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))
Sum along the second dimension:
s = x.sum(axis=1)
Find which cells are above a threshold:
(x > 0.5).nonzero()
Remove every even-indexed slice along the third dimension:
x[:, :, ::2]
Also, many useful libraries work with NumPy arrays. For example, statistical analysis and visualization libraries.
Even if you don't have performance problems, learning NumPy is worth the effort.
Here is how I did it (that's to prompt browser to download the csv file):
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=file.csv');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
echo "\xEF\xBB\xBF"; // UTF-8 BOM
echo $csv_file_content;
exit();
The only thing it fixed UTF8 encoding problem in CSV preview when you hit space bar on Mac.. but not in Excel Mac 2008... don't know why
You can use ECMAScript 6's String.prototype.startsWith()
method, but it's not yet supported in all browsers. You'll want to use a shim/polyfill to add it on browsers that don't support it. Creating an implementation that complies with all the details laid out in the spec is a little complicated. If you want a faithful shim, use either:
String.prototype.startsWith
shim, orString.prototype.startsWith
.Once you've shimmed the method (or if you're only supporting browsers and JavaScript engines that already have it), you can use it like this:
console.log("Hello World!".startsWith("He")); // true
var haystack = "Hello world";
var prefix = 'orl';
console.log(haystack.startsWith(prefix)); // false

How about something like: Using HTML Agility Pack
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
foreach (HtmlNode table in doc.DocumentNode.SelectNodes("//table")) {
Console.WriteLine("Found: " + table.Id);
foreach (HtmlNode row in table.SelectNodes("tr")) {
Console.WriteLine("row");
foreach (HtmlNode cell in row.SelectNodes("th|td")) {
Console.WriteLine("cell: " + cell.InnerText);
}
}
}
Note that you can make it prettier with LINQ-to-Objects if you want:
var query = from table in doc.DocumentNode.SelectNodes("//table").Cast<HtmlNode>()
from row in table.SelectNodes("tr").Cast<HtmlNode>()
from cell in row.SelectNodes("th|td").Cast<HtmlNode>()
select new {Table = table.Id, CellText = cell.InnerText};
foreach(var cell in query) {
Console.WriteLine("{0}: {1}", cell.Table, cell.CellText);
}
It tells the cpu to activate interrupt vector 0x80, which on Linux OSes is the system-call interrupt, used to invoke system functions like open()
for files, et cetera.
Here is the simplest code for extracting text
code:
# importing required modules
import PyPDF2
# creating a pdf file object
pdfFileObj = open('filename.pdf', 'rb')
# creating a pdf reader object
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
# printing number of pages in pdf file
print(pdfReader.numPages)
# creating a page object
pageObj = pdfReader.getPage(5)
# extracting text from page
print(pageObj.extractText())
# closing the pdf file object
pdfFileObj.close()
If you want to see which IP addresses are in use on a specific subnet then there are several different IP Address managers.

Assuming that end_date
and start_date
are both of class ActiveSupport::TimeWithZone
in Rails, then you can use:
(end_date.to_date - start_date.to_date).to_i
I was also getting same issue as i tried using value 0 in non-based indexing,i.e starting with 1, not with zero
string s = (string)o; // 1
Throws InvalidCastException if o
is not a string
. Otherwise, assigns o
to s
, even if o
is null
.
string s = o as string; // 2
Assigns null
to s
if o
is not a string
or if o
is null
. For this reason, you cannot use it with value types (the operator could never return null
in that case). Otherwise, assigns o
to s
.
string s = o.ToString(); // 3
Causes a NullReferenceException if o
is null
. Assigns whatever o.ToString()
returns to s
, no matter what type o
is.
Use 1 for most conversions - it's simple and straightforward. I tend to almost never use 2 since if something is not the right type, I usually expect an exception to occur. I have only seen a need for this return-null type of functionality with badly designed libraries which use error codes (e.g. return null = error, instead of using exceptions).
3 is not a cast and is just a method invocation. Use it for when you need the string representation of a non-string object.
This error occurs when you have database is not in sync with your model and vice versa. To overcome this , follow the below steps -
a) Add a migration file using add-migration <{Migration File Name}> through the nuget package manager console. This migration file will have the script to sync anything not in sync between Db and code.
b) Update the database using update-database command. This will update the database with the latest changes in your model.
If this does not help, try these steps after adding the line of code in the Application_Start method of Global.asax.cs file -
Database.SetInitializer<VidlyDbContext>(new DropCreateDatabaseIfModelChanges<VidlyDbContext>());

Consider the following if you run into any further problems, but I'm guessing that the above will work for you:
To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
What you tried was df['V1','V2']
this will raise a KeyError
as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]]
.
import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()
img {
position: absolute;
clip: rect(0px, 140px, 140px, 0px);
}
<img src="w3css.gif" width="100" height="140" />
Another option would be to build it automatically using Eclipse. Of course if you have continuous integration environment Ant or Maven is recommended. The export alternative is not very convenient because you have to configure every time the export properties.
STEPS:
Enable "Project Archives" support; this might depend on your project (I used it on Java EE/Web project). Right-click project root directory; Configure -> Add Project Archives Support.
Go and create a new archive in the "Project Archives" top dir. You have only jar option, but name you archive *.war.
Configure Fileset-s, i.e what files to be included. Typical is to configure two filesets similar how the Web Deployment Assembly (project property) is configured.
You might need to tweek the fileset exclude property depending where you placed some of the config files or you might need more filesets, but the idea is that once you configured this you don't need to change it.
Build the archive manually or publish directly to server; but is also automatically built for you by Eclipse
To fully script-automate:
Create:
7z -mhc=on -mhe=on -pPasswordHere a %ZipDest% %WhatYouWantToZip%
Unzip:
7z x %ZipFile% -pPasswordHere
(Depending, you might need to: Set Path=C:\Program Files\7-Zip;%Path% )
You could use animation like this:
-webkit-animation: spin 1s infinite linear;
@-webkit-keyframes spin {
0% {-webkit-transform: rotate(0deg)}
100% {-webkit-transform: rotate(360deg)}
}

I am using GULP CLI 2.0.1 (installed globally) and GULP 4.0.0 (installed locally) here is how you do it without any additional plugin. I think the code is quite self-explanatory.
var cp = require('child_process'),
{ src, dest, series, parallel, watch } = require('gulp');
// == availableTasks: log available tasks to console
function availableTasks(done) {
var command = 'gulp --tasks-simple';
if (process.argv.indexOf('--verbose') > -1) {
command = 'gulp --tasks';
}
cp.exec(command, function(err, stdout, stderr) {
done(console.log('Available tasks are:\n' + stdout));
});
}
availableTasks.displayName = 'tasks';
availableTasks.description = 'Log available tasks to console as plain text list.';
availableTasks.flags = {
'--verbose': 'Display tasks dependency tree instead of plain text list.'
};
exports.availableTasks = availableTasks;
And run from the console:
gulp availableTasks
Then run and see the differences:
gulp availableTasks --verbose
If you are just going to substitute it into a URL I suppose one field would do - so you can form a URL like
http://maps.google.co.uk/maps?q=12.345678,12.345678&z=6
but as it is two pieces of data I would store them in separate fields

SOLVED
As other have said C maps in row order
#include <stdio.h>
int main(int argc, char **argv) {
int i, j, k;
int arr[5][3];
int *arr2 = (int*)arr;
for (k=0; k<15; k++) {
arr2[k] = k;
printf("arr[%d] = %2d\n", k, arr2[k]);
}

for (j=0; j< 3; j++) {
printf("arr2[%d][%d] = %2d\n", i, j ,arr[i][j]);
}
}
}
Output:

From the first answer,
"Using Mongoose, a user can define the schema for the documents in a particular collection. It provides a lot of convenience in the creation and management of data in MongoDB."
You can now also define schema with mongoDB native driver using
##For new collection
`db.createCollection("recipes",
validator: { $jsonSchema: {
<<Validation Rules>>
}
}
)`
##For existing collection
`db.runCommand( {
collMod: "recipes",
validator: { $jsonSchema: {
<<Validation Rules>>
}
}
} )`
##full example
`db.createCollection("recipes", {
validator: {
$jsonSchema: {
bsonType: "object",
required: ["name", "servings", "ingredients"],
additionalProperties: false,
properties: {
_id: {},
name: {
bsonType: "string",
description: "'name' is required and is a string"
},
servings: {
bsonType: ["int", "double"],
minimum: 0,
description:
"'servings' is required and must be an integer with a minimum of zero."
},
cooking_method: {
enum: [

});`
Insert collection Example
`db.recipes.insertOne({

You can simply use the indexOf method on the input string:
function hasWhiteSpace(s) {
return s.indexOf(' ') >= 0;
}
Or you can use the test method, on a simple RegEx:
function hasWhiteSpace(s) {
return /\s/g.test(s);
}
This will also check for other white space characters like Tab.
teststr=$'test1\n'
teststr+=$'test2\n'
echo "$teststr"
I was using restify instead of express and ran into the same problem. The solution was to do:
server.use(restify.bodyParser());
In jQuery, check whether you have hit the bottom of page using scroll function. Once you hit that, make an ajax call (you can show a loading image here till ajax response) and get the next set of data, append it to the div. This function gets executed as you scroll down the page again.
$(window).scroll(function() {
if($(window).scrollTop() == $(document).height() - $(window).height()) {
// ajax call get data from server and append to the div
}
});
You would have to tune it according to your environment.
Sometimes it's more useful to increase the size of the backlog (acceptCount) instead of the maximum number of threads.
Say, instead of
<Connector ... maxThreads="500" acceptCount="50"
you use
<Connector ... maxThreads="300" acceptCount="150"
you can get much better performance in some cases, cause there would be less threads disputing the resources and the backlog queue would be consumed faster.
In any case, though, you have to do some benchmarks to really know what is best.
I understand this isn't what OP asked for, but I still think it is worth to point out how to do it with printf. I almost always prefer using it over std::cout (even with no previous C background).
printf("%.2X", a);
'2' defines the precision, 'X' or 'x' defines case.
Variables are not defined, but declared.

I'm surprised that no one has mentioned the list-style-image property
ul {
list-style-image: url('images/ico-list-bullet.png');
}
So i finally figured out how to do this. The basic idea is that you have the token you get the first time you ask for authentication. This first token has a refresh token. The first original token expires after an hour. After an hour you have to use the refresh token from the first token to get a new usable token. You use $client->refreshToken($refreshToken)
to retrieve a new token. I will call this "temp token." You need to store this temp token as well because after an hour it expires as well and note it does not have a refresh token associated with it. In order to get a new temp token you need to use the method you used before and use the first token's refreshtoken. I have attached code below, which is ugly, but im new at this...
//pull token from database
$tokenquery="SELECT * FROM token WHERE type='original'";
$tokenresult = mysqli_query($cxn,$tokenquery);
if($tokenresult!=0)
{
$tokenrow=mysqli_fetch_array($tokenresult);
extract($tokenrow);
}
$time_created = json_decode($token)->created;
$t=time();
$timediff=$t-$time_created;
echo $timediff."<br>";
$refreshToken= json_decode($token)->refresh_token;
//start google client note:
$client = new Google_Client();
$client->setApplicationName('');
$client->setScopes(array());
$client->setClientId('');
$client->setClientSecret('');
$client->setRedirectUri('');
$client->setAccessType('offline');
$client->setDeveloperKey('');
//resets token if expired
if(($timediff>3600)&&($token!=''))
{
echo $refreshToken."</br>";
$refreshquery="SELECT * FROM token WHERE type='refresh'";
$refreshresult = mysqli_query($cxn,$refreshquery);
//if a refresh token is in there...
if($refreshresult!=0)
{
$refreshrow=mysqli_fetch_array($refreshresult);
extract($refreshrow);
$refresh_created = json_decode($token)->created;
$refreshtimediff=$t-$refresh_created;
echo "Refresh Time Diff: ".$refreshtimediff."</br>";
//if refresh token is expired
if($refreshtimediff>3600)
{
$client->refreshToken($refreshToken);
$newtoken=$client->getAccessToken();
echo $newtoken."</br>";
$tokenupdate="UPDATE token SET token='$newtoken' WHERE type='refresh'";
mysqli_query($cxn,$tokenupdate);
$token=$newtoken;
echo "refreshed again";
}
//if the refresh token hasn't expired, set token as the refresh token
else
{
$client->setAccessToken($token);
echo "use refreshed token but not time yet";
}
}
//if a refresh token isn't in there...
else
{
$client->refreshToken($refreshToken);
$newtoken=$client->getAccessToken();
echo $newtoken."</br>";
$tokenupdate="INSERT INTO token (type,token) VALUES ('refresh','$newtoken')";
mysqli_query($cxn,$tokenupdate);
$token=$newtoken;
echo "refreshed for first time";
}
}
//if token is still good.
if(($timediff<3600)&&($token!=''))
{
$client->setAccessToken($token);
}
$service = new Google_DfareportingService($client);
In XML 1.0, the XML Declaration is optional. See section 2.8 of the XML 1.0 Recommendation, where it says it "should" be used -- which means it is recommended, but not mandatory. In XML 1.1, however, the declaration is mandatory. See section 2.8 of the XML 1.1 Recommendation, where it says "MUST" be used. It even goes on to state that if the declaration is absent, that automatically implies the document is an XML 1.0 document.
Note that in an XML Declaration the encoding
and standalone
are both optional. Only the version
is mandatory. Also, these are not attributes, so if they are present they must be in that order: version
, followed by any encoding
, followed by any standalone

<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" standalone="yes"?>
<?xml version="1.0" encoding="UTF-16" standalone="yes"?>
If you don't specify the encoding in this way, XML parsers try to guess what encoding is being used. The XML 1.0 Recommendation describes one possible way character encoding can be autodetected. In practice, this is not much of a problem if the input is encoded as UTF-8, UTF-16 or US-ASCII. Autodetection doesn't work when it encounters 8-bit encodings that use characters outside the US-ASCII range (e.g. ISO 8859-1) -- avoid creating these if you can.
The standalone
indicates whether the XML document can be correctly processed without the DTD or not. People rarely use it. These days, it is a bad to design an XML format that is missing information without its DTD.
Update:
A "prolog error/invalid utf-8 encoding" error indicates that the actual data the parser found inside the file did not match the encoding that the XML declaration says it is. Or in some cases the data inside the file did not match the autodetected encoding.
Since your file contains a byte-order-mark (BOM) it should be in UTF-16 encoding. I suspect that your declaration says <?xml version="1.0" encoding="UTF-8"?>
which is obviously incorrect when the file has been changed into UTF-16 by NotePad. The simple solution is to remove the encoding
and simply say <?xml version="1.0"?>
. You could also edit it to say encoding="UTF-16"
but that would be wrong for the original file (which wasn't in UTF-16) or if the file somehow gets changed back to UTF-8 or some other encoding.
Don't bother trying to remove the BOM -- that's not the cause of the problem. Using NotePad or WordPad to edit XML is the real problem!
From axios docs you have baseURL and url
baseURL
will be prepended to url
when making requests. So you can define baseURL
as http://127.0.0.1:8000
and make your requests to /url
// `url` is the server URL that will be used for the request url: '/user', // `baseURL` will be prepended to `url` unless `url` is absolute. // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs // to methods of that instance. baseURL: 'https://some-domain.com/api/',
Take a look at the domReady script that allows setting up of multiple functions to execute when the DOM has loaded. It's basically what the Dom ready does in many popular JavaScript libraries, but is lightweight and can be taken and added at the start of your external script file.
Example usage
// add reference to domReady script or place
// contents of script before here
function codeAddress() {
}
domReady(codeAddress);
You can get network interfaces with NetworkInterface.getNetworkInterfaces()
, then the IP addresses off the NetworkInterface objects returned with .getInetAddresses()
, then the string representation of those addresses with .getHostAddress()
.
If you make a @Configuration
class which implements ApplicationListener<EmbeddedServletContainerInitializedEvent>
, you can override onApplicationEvent
to get the port number once it's set.
@Override
public void onApplicationEvent(EmbeddedServletContainerInitializedEvent event) {
int port = event.getEmbeddedServletContainer().getPort();
}
The easiest way to achieve this, without changing the HTML table
-based structure, is to use a class-name on the tr
elements containing a header, such as .header
, to give:
<table border="0">
<tr class="header">
<td colspan="2">Header</td>
</tr>
<tr>
<td>data</td>
<td>data</td>
</tr>
<tr>
<td>data</td>
<td>data</td>
</tr>
<tr class="header">
<td colspan="2">Header</td>
</tr>
<tr>
<td>date</td>
<td>data</td>
</tr>
<tr>
<td>data</td>
<td>data</td>
</tr>
<tr>
<td>data</td>
<td>data</td>
</tr>
</table>
And the jQuery:
// bind a click-handler to the 'tr' elements with the 'header' class-name:
$('tr.header').click(function(){
/* get all the subsequent 'tr' elements until the next 'tr.header',
set the 'display' property to 'none' (if they're visible), to 'table-row'
if they're not: */
$(this).nextUntil('tr.header').css('display', function(i,v){
return this.style.display === 'table-row' ? 'none' : 'table-row';
});
});
In the linked demo I've used CSS to hide the tr
elements that don't have the header
class-name; in practice though (despite the relative rarity of users with JavaScript disabled) I'd suggest using JavaScript to add the relevant class-names, hiding and showing as appropriate:
// hide all 'tr' elements, then filter them to find...
$('tr').hide().filter(function () {
// only those 'tr' elements that have 'td' elements with a 'colspan' attribute:
return $(this).find('td[colspan]').length;
// add the 'header' class to those found 'tr' elements
}).addClass('header')
// set the display of those elements to 'table-row':
.css('display', 'table-row')
// bind the click-handler (as above)
.click(function () {
$(this).nextUntil('tr.header').css('display', function (i, v) {
return this.style.display === 'table-row' ? 'none' : 'table-row';
});
});

For me, the below helped
Find org.apache.http.legacy.jar
which is in Android/Sdk/platforms/android-23/optional,
add it to your dependency.
In addition to @JBNizet's answer, my general use case for ifPresent
is to combine .isPresent()
and .get()
:
Old way:
Optional opt = getIntOptional();
if(opt.isPresent()) {
Integer value = opt.get();
// do something with value
}
New way:
Optional opt = getIntOptional();
opt.ifPresent(value -> {
// do something with value
})
This, to me, is more intuitive.
Create a folder where you want to keep the code, and right click on it. Choose SVN Checkout... and type http://wittytwitter.googlecode.com/svn/trunk into the URL of repository field.
You can also run
svn checkout http://wittytwitter.googlecode.com/svn/trunk
from the command line in the folder you want to keep it (svn.exe has to be in your path, of course).
This isn't quite the answer you were looking for, but it's the solution I came to when I had the same question.
I'm a pretty serious Notepad++ user, so don't take this the wrong way. I have started using NetBeans 8
to develop websites in addition to Notepad++ because you can set it to autoformat on save for all your languages, and there are a ton of configuration options for how the formatting looks, down to the most minute detail. You might look into it and find it is a worthy tool to use in conjunction with notepad++. It's also open source, completely free, and has a bunch of plugins and other useful things like automatically compiling Sass if you use that too. It's definitely not as quick as NP++ so it's not great for small edits, but it can be nice for a long coding session.
As one person may have already suggested,
I passed the ISO 8601 date string directly to moment like so...
`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`
or
`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`
either of these solutions will give you the same result.
`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`
while @vitocorleone is technically correct. If you have already installed, there is no need to reinstall. You just need to add it to your path. You will find yourself doing this for many of the tools for the mean stack so you should get used to doing it. You don't want to have to be in the folder that holds the executable to run it.
at the end of the line type (assuming this is where you installed it)
;C:\Program Files (x86)\git\cmd
click ok, ok, and ok to save
This essentially tells the OS.. if you don't find this executable in the folder I am typing in, look in Path to fide where it is.
Also you will see some other parameters after #!/bin/bash,
for example
#!/bin/bash -v -x
read this to get more idea.
https://unix.stackexchange.com/questions/124272/what-do-the-arguments-v-and-x-mean-to-bash .
This is how I did it, I hope it brings a new perspective how this works on Swift.
In this example below I will get the any string between []
var sample = "this is an [hello] amazing [world]"
var regex = NSRegularExpression(pattern: "\\[.+?\\]"
, options: NSRegularExpressionOptions.CaseInsensitive
, error: nil)
var matches = regex?.matchesInString(sample, options: nil
, range: NSMakeRange(0, countElements(sample))) as Array<NSTextCheckingResult>
for match in matches {
let r = (sample as NSString).substringWithRange(match.range)//cast to NSString is required to match range format.
println("found= \(r)")
}
Collection initializers are only available in VB.NET 2010, released 2010-04-12:

getClass() has the restriction that objects are only equal to other objects of the same class, the same run time type, as illustrated in the output of below code:
class ParentClass{
}
public class SubClass extends ParentClass{
public static void main(String []args){
ParentClass parentClassInstance = new ParentClass();
SubClass subClassInstance = new SubClass();
if(subClassInstance instanceof ParentClass){
System.out.println("SubClass extends ParentClass. subClassInstance is instanceof ParentClass");
}
if(subClassInstance.getClass() != parentClassInstance.getClass()){
System.out.println("Different getClass() return results with subClassInstance and parentClassInstance ");
}
}
}
Outputs:
SubClass extends ParentClass. subClassInstance is instanceof ParentClass.
Different getClass() return results with subClassInstance and parentClassInstance.
Presumably you have it in a variable and are using JSON.parse(data);
. In which case, use:
JSON.parse(data.replace(/"/g,'"'));
You might want to fix your JSON-writing script though, because "
is not valid in a JSON object.
I have a simple example here to display date and time with Millisecond......
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class MyClass{
public static void main(String[]args){
LocalDateTime myObj = LocalDateTime.now();
DateTimeFormatter myFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS);
String forDate = myObj.format(myFormat);
System.out.println("The Date and Time are: " + forDate);
}
}

But all forgot there is another option.
Only at the end of a file, of course.
While Python 3 deals in Unicode, the Windows console or POSIX tty that you're running inside does not. So, whenever you print
, or otherwise send Unicode strings to stdout
, and it's attached to a console/tty, Python has to encode it.
The error message indirectly tells you what character set Python was trying to use:
File "C:\Python32\lib\encodings\cp850.py", line 19, in encode
This means the charset is cp850
.
You can test or yourself that this charset doesn't have the appropriate character just by doing '\u2013'.encode('cp850')
. Or you can look up cp850 online (e.g., at Wikipedia).
It's possible that Python is guessing wrong, and your console is really set for, say UTF-8. (In that case, just manually set sys.stdout.encoding='utf-8'
.) It's also possible that you intended your console to be set for UTF-8 but did something wrong. (In that case, you probably want to follow up at superuser.com.)
But if nothing is wrong, you just can't print that character. You will have to manually encode it with one of the non-strict error-handlers. For example:
>>> '\u2013'.encode('cp850')
UnicodeEncodeError: 'charmap' codec can't encode character '\u2013' in position 0: character maps to <undefined>
>>> '\u2013'.encode('cp850', errors='replace')
b'?'
So, how do you print a string that won't print on your console?
You can replace every print
function with something like this:
>>> print(r['body'].encode('cp850', errors='replace').decode('cp850'))
?
… but that's going to get pretty tedious pretty fast.
The simple thing to do is to just set the error handler on sys.stdout
:
>>> sys.stdout.errors = 'replace'
>>> print(r['body'])
?
For printing to a file, things are pretty much the same, except that you don't have to set f.errors
after the fact, you can set it at construction time. Instead of this:
with open('path', 'w', encoding='cp850') as f:
Do this:
with open('path', 'w', encoding='cp850', errors='replace') as f:
… Or, of course, if you can use UTF-8 files, just do that, as Mark Ransom's answer shows:
with open('path', 'w', encoding='utf-8') as f:
NOTE: Despite (or rather, because of) succinctness and apparent elegance, this algorithm is by no means a high-quality one in terms of randomness. Look for e.g. those listed in this answer for better results.
(Originally adapted from a clever idea presented in a comment to another answer.)
var seed = 1;
function random() {
var x = Math.sin(seed++) * 10000;
return x - Math.floor(x);
}
You can set seed
to be any number, just avoid zero (or any multiple of Math.PI).
The elegance of this solution, in my opinion, comes from the lack of any "magic" numbers (besides 10000, which represents about the minimum amount of digits you must throw away to avoid odd patterns - see results with values 10, 100, 1000). Brevity is also nice.
It's a bit slower than Math.random() (by a factor of 2 or 3), but I believe it's about as fast as any other solution written in JavaScript.
If possible try this one instant solution:
Intent intent =new Intent(getApplicationBaseContext,second_Act.class);
StartActivity(intent);
Answer is very simple use the .NET Framework tools sn.exe
. So open the Visual Studio 2008 Command Prompt and then point to the dll’s folder you want to get the public key,
Use the following command,
sn –T myDLL.dll
This will give you the public key token. Remember one thing this only works if the assembly has to be strongly signed.
Example
C:\WINNT\Microsoft.NET\Framework\v3.5>sn -T EdmGen.exe Microsoft (R) .NET Framework Strong Name Utility Version 3.5.21022.8 Copyright (c) Microsoft Corporation. All rights reserved. Public key token is b77a5c561934e089
A tty is a terminal (it stands for teletype - the original terminals used a line printer for output and a keyboard for input!). A terminal is a basically just a user interface device that uses text for input and output.
A pty is a pseudo-terminal - it's a software implementation that appears to the attached program like a terminal, but instead of communicating directly with a "real" terminal, it transfers the input and output to another program.
For example, when you ssh in to a machine and run ls
, the ls
command is sending its output to a pseudo-terminal, the other side of which is attached to the SSH daemon.

The title "WPF Label Foreground Color" is very simple (exactly what I was looking for) but the OP's code is so cluttered it's easy to miss how simple it can be to set text foreground color on two different labels:
<StackPanel>
<Label Foreground="Red">Red text</Label>
<Label Foreground="Blue">Blue text</Label>
</StackPanel>
In summary, No, there was nothing wrong with your snippet.
Here are a variety of ways to do this, along with some benchmarks. The best methods are versions using optimized code from other libraries. The bottleneck.move_mean
method is probably best all around. The scipy.convolve
approach is also very fast, extensible, and syntactically and conceptually simple, but doesn't scale well for very large window values. The numpy.cumsum
method is good if you need a pure numpy
approach.
Note: Some of these (e.g. bottleneck.move_mean
) are not centered, and will shift your data.

It depends in what mode you are compiling. long long is not part of the C++ standard but only (usually) supported as extension. This affects the type of literals. Decimal integer literals without any suffix are always of type int if int is big enough to represent the number, long otherwise. If the number is even too big for long the result is implementation-defined (probably just a number of type long int that has been truncated for backward compatibility). In this case you have to explicitly use the LL suffix to enable the long long extension (on most compilers).
The next C++ version will officially support long long in a way that you won't need any suffix unless you explicitly want the force the literal's type to be at least long long. If the number cannot be represented in long the compiler will automatically try to use long long even without LL suffix. I believe this is the behaviour of C99 as well.

Another option is to use Apache Commons StrBuilder, which has the functionality that's lacking in StringBuilder.
As of version 3.6 StrBuilder has been deprecated in favour of TextStringBuilder which has the same functionality
It means three things.
First public
means that any other object can access it.
static
means that the class in which it resides doesn't have to be instantiated first before the function can be called.
void
means that the function does not return a value.
Since you are just learning, don't worry about the first two too much until you learn about classes, and the third won't matter much until you start writing functions (other than main that is).
Best piece of advice I got when learning to program, and which I pass along to you, is don't worry about the little details you don't understand right away. Get a broad overview of the fundamentals, then go back and worry about the details. The reason is that you have to use some things (like public static void
) in your first programs which can't really be explained well without teaching you about a bunch of other stuff first. So, for the moment, just accept that that's the way it's done, and move on. You will understand them shortly.
If none of the above answers works for you, try the following: Get the "org.eclipse.equinox.simpleconfigurator" and the "org.eclipse.update" folders found under the "eclipse\configuration" from a working Eclipse instance (can be the stock Eclipse downloaded from their website) and replace them in your Eclipse installation directory. This fixed it for me.
For anybody coming here looking for a getTickCount() implementation for iOS, here is mine after putting various sources together.
Previously I had a bug in this code (I divided by 1000000 first) which was causing some quantisation of the output on my iPhone 6 (perhaps this was not an issue on iPhone 4/etc or I just never noticed it). Note that by not performing that division first, there is some risk of overflow if the numerator of the timebase is quite large. If anybody is curious, there is a link with much more information here: https://stackoverflow.com/a/23378064/588476
In light of that information, maybe it is safer to use Apple's function CACurrentMediaTime
!
I also benchmarked the mach_timebase_info
call and it takes approximately 19ns on my iPhone 6, so I removed the (not threadsafe) code which was caching the output of that call.
#include <mach/mach.h>
#include <mach/mach_time.h>
uint64_t getTickCount(void)
{
mach_timebase_info_data_t sTimebaseInfo;
uint64_t machTime = mach_absolute_time();
// Convert to milliseconds
mach_timebase_info(&sTimebaseInfo);
machTime *= sTimebaseInfo.numer;
machTime /= sTimebaseInfo.denom;
machTime /= 1000000; // convert from nanoseconds to milliseconds
return machTime;
}
Do be aware of the potential risk of overflow depending on the output of the timebase call. I suspect (but do not know) that it might be a constant for each model of iPhone. on my iPhone 6 it was 125/3
.
The solution using CACurrentMediaTime()
is quite trivial:
uint64_t getTickCount(void)
{
double ret = CACurrentMediaTime();
return ret * 1000;
}
Open the file again using vi. and then press the insert button to begin editing it.
So I created an account just so I could help fix this problem that is plaguing a lot of people and where the fixes above aren't working.
If you get this error and nothing here helps. Try clicking the "Resume program play button" until the program finishes past the error. Then click in the console tab next to debug and read the red text.
I was getting that source code error even though my issue was trying to insert a value into a null Array. Step 1 Click the resume button
You can use String.Format function to add second class based on condition:
<div class="@String.Format("details {0}", Details.Count > 0 ? "show" : "hide")">
Maybe in your data source add a column which does a sumif over all rows.
Not sure what your data looks like but something like =(sumif([column holding pivot row heads),[current row head value in row], probability column)>.2).
This will give you a True when the pivot table will show >20%.
Then add a filter on your pivot table on this column for TRUE values
No real need for the JSON.NET package. You could use JavaScriptSerializer
. The Serialize
method will turn a managed type instance into a JSON string.
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(instanceOfThing);
Since my requirement is override the existing textView get from findViewById(getResources().getIdentifier("xxx", "id", "android"));
, so I can't simply try onDraw()
of other answer.
But I just figure out the correct steps to fixed my problem, here is the final result from Layout Inspector:
Since what I wanted is merely remove the top spaces, so I don't have to choose other font to remove bottom spaces.
Here is the critical code to fixed it:
Typeface mfont = Typeface.createFromAsset(getResources().getAssets(), "fonts/myCustomFont.otf");
myTextView.setTypeface(mfont);
myTextView.setPadding(0, 0, 0, 0);
myTextView.setIncludeFontPadding(false);
The first key is set custom font "fonts/myCustomFont.otf" which has the space on bottom but not on the top, you can easily figure out this by open otf file and click any font in android Studio:
As you can see, the cursor on the bottom has extra spacing but not on the top, so it fixed my problem.
The second key is you can't simply skip any of the code, otherwise it might not works. That's the reason you can found some people comment that an answer is working and some other people comment that it's not working.
Let's illustrated what will happen if I remove one of them.
Without setTypeface(mfont);
:
Without setPadding(0, 0, 0, 0);
:
Without setIncludeFontPadding(false);
:
Without 3 of them (i.e. the original):
<div><p>some unnecessary content</p></div>
div{
border: 1px solid red;
width: 40%;
padding: 40%;
box-sizing: border-box;
position: relative;
}
p{
position: absolute;
top: 0;
left: 0;
}
For this to work i think you need to define the padding to ex. top? like this:
<div><p>some unnecessary content</p></div>
div{
border: 1px solid red;
width: 40%;
padding-top: 40%;
box-sizing: border-box;
position: relative;
}
p{
position: absolute;
top: 0;
left: 0;
}
anyways, thats how i got it to work, since with just padding all arround it would not be a square.
The github help link helped me sort out this problem. Looks like the ssh key was not added to the ssh-agent. This is what I ended up doing.
Command 1:
Ensure ssh-agent is enabled. The command starts the ssh-agent in the background:
eval "$(ssh-agent -s)"
Command 2:
Add your SSH key to the ssh-agent:
ssh-add ~/.ssh/id_rsa
There are performance gains you can get by installing TensorFlow from the source even if you have a GPU and use it for training and inference. The reason is that some TF operations only have CPU implementation and cannot run on your GPU.
Also, there are some performance enhancement tips that makes good use of your CPU. TensorFlow's performance guide recommends the following:
Placing input pipeline operations on the CPU can significantly improve performance. Utilizing the CPU for the input pipeline frees the GPU to focus on training.
For best performance, you should write your code to utilize your CPU and GPU to work in tandem, and not dump it all on your GPU if you have one. Having your TensorFlow binaries optimized for your CPU could pay off hours of saved running time and you have to do it once.

You can use the folowing code:
def float_range(initVal, itemCount, step):
for x in xrange(itemCount):
yield initVal
initVal += step
[x for x in float_range(1, 3, 0.1)]

listener interface
public interface OnEventListener {
void onEvent(EventResult er);
// or void onEvent(); as per your need
}
then in your class say Event
class
public class Event {
private OnEventListener mOnEventListener;
public void setOnEventListener(OnEventListener listener) {
mOnEventListener = listener;
}
public void doEvent() {
/*
* code code code
*/
// and in the end
if (mOnEventListener != null)
mOnEventListener.onEvent(eventResult); // event result object :)
}
}
in your driver class MyTestDriver
public class MyTestDriver {
public static void main(String[] args) {
Event e = new Event();
e.setOnEventListener(new OnEventListener() {
public void onEvent(EventResult er) {
// do your work.
}
});
e.doEvent();
}
}
You can avoid compilation errors if you remove the method definitions from the header files and let the classes contain only the method declarations and variable declarations/definitions. The method definitions should be placed in a .cpp file (just like a best practice guideline says).
The down side of the following solution is (assuming that you had placed the methods in the header file to inline them) that the methods are no longer inlined by the compiler and trying to use the inline keyword produces linker errors.
//A.h
#ifndef A_H
#define A_H
class B;
class A
{
int _val;
B* _b;
public:
A(int val);
void SetB(B *b);
void Print();
};
#endif
//B.h
#ifndef B_H
#define B_H
class A;
class B
{
double _val;
A* _a;
public:
B(double val);
void SetA(A *a);
void Print();
};
#endif
//A.cpp
#include "A.h"
#include "B.h"
#include <iostream>
using namespace std;
A::A(int val)
:_val(val)
{
}
void A::SetB(B *b)
{
_b = b;
cout<<"Inside SetB()"<<endl;
_b->Print();
}
void A::Print()
{
cout<<"Type:A val="<<_val<<endl;
}

_a = a;

_a->Print();
}
void B::Print()

cout<<"Type:B val="<<_val<<endl;
}

If you are injecting something that needs the script tag, you may get an uncaught syntax error and say illegal token. To avoid this, be sure to escape the forward slashes in your closing script tag(s). ie;
var output += '<\/script>';
Same goes for any closing tags, such as a form tag.
Similar to @craig, I recently built a shortcut library.
https://github.com/blainekasten/shortcut.js
Chainable API with support for multple functions bound to one shortcut.
I know it's been a while on this question, but I was just looking for the same answer and found this seems to be the simplest solution:
select * from sales where datediff(dd, salesDate, '20101111') = 0
I actually use it more to find things within the last day or two, so my version looks like this:
select * from sales where datediff(dd, salesDate, getdate()) = 0
And by changing the 0 for today to a 1 I get yesterday's transactions, 2 is the day before that, and so on. And if you want everything for the last week, just change the equals to a less-than-or-equal-to:
select * from sales where datediff(dd, salesDate, getdate()) <= 7

This answer aims to force an image pull in a situation where your node has already downloaded an image with the same name, therefore even though you push a new image to container registry, when you spin up some pods, your pod says "image already present".
For a case in Azure Container Registry (probably AWS and GCP also provides this):
You can look to your Azure Container Registry and by checking the manifest creation date you can identify what image is the most recent one.
Then, copy its digest hash (which has a format of sha256:xxx...xxx
).
You can scale down your current replica by running command below. Note that this will obviously stop your container and cause downtime.
kubectl scale --replicas=0 deployment <deployment-name> -n <namespace-name>
kubectl get deployments.apps <deployment-name> -o yaml > deployment.yaml
Then change the line with image field from <image-name>:<tag>
to <image-name>@sha256:xxx...xxx
, save the file.
Now you can scale up your replicas again. New image will be pulled with its unique digest.
Note: It is assumed that, imagePullPolicy: Always field is present in the container.
The best way to do this is using Behaviur Subject
, here is an example:
var sub = new rxjs.BehaviorSubject([0, 1])
sub.next([2, 3])
setTimeout(() => {sub.next([4, 5])}, 1500)
sub.subscribe(a => console.log(a)) //2, 3 (current value) -> wait 2 sec -> 4, 5
The answer from ks1322 helped me to identify the issue while using docker-compose exec
:
If you omit the -T
flag, docker-compose exec
add a special character that break output, we see b
instead of 1b
:
$ test=$(/usr/local/bin/docker-compose exec db bash -c "echo 1")
$ echo "${test}b"
b
echo "${test}" | cat -vte
1^M$
With -T
flag, docker-compose exec
works as expected:
$ test=$(/usr/local/bin/docker-compose exec -T db bash -c "echo 1")
$ echo "${test}b"
1b
One way is to stack the frames on top of each other, then you can simply raise one above the other in the stacking order. The one on top will be the one that is visible. This works best if all the frames are the same size, but with a little work you can get it to work with any sized frames.
Note: for this to work, all of the widgets for a page must have that page (ie: self
) or a descendant as a parent (or master, depending on the terminology you prefer).
Here's a bit of a contrived example to show you the general concept:
try:
import tkinter as tk # python 3
from tkinter import font as tkfont # python 3
except ImportError:
import Tkinter as tk # python 2
import tkFont as tkfont # python 2
class SampleApp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.title_font = tkfont.Font(family='Helvetica', size=18, weight="bold", slant="italic")
# the container is where we'll stack a bunch of frames
# on top of each other, then the one we want visible
# will be raised above the others
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (StartPage, PageOne, PageTwo):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
# put all of the pages in the same location;
# the one on the top of the stacking order
# will be the one that is visible.
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("StartPage")
def show_frame(self, page_name):
'''Show a frame for the given page name'''
frame = self.frames[page_name]
frame.tkraise()
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is the start page", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button1 = tk.Button(self, text="Go to Page One",
command=lambda: controller.show_frame("PageOne"))
button2 = tk.Button(self, text="Go to Page Two",
command=lambda: controller.show_frame("PageTwo"))
button1.pack()
button2.pack()
class PageOne(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is page 1", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button = tk.Button(self, text="Go to the start page",
command=lambda: controller.show_frame("StartPage"))
button.pack()
class PageTwo(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is page 2", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button = tk.Button(self, text="Go to the start page",
command=lambda: controller.show_frame("StartPage"))
button.pack()
if __name__ == "__main__":
app = SampleApp()
app.mainloop()
If you find the concept of creating instance in a class confusing, or if different pages need different arguments during construction, you can explicitly call each class separately. The loop serves mainly to illustrate the point that each class is identical.
For example, to create the classes individually you can remove the loop (for F in (StartPage, ...)
with this:
self.frames["StartPage"] = StartPage(parent=container, controller=self)
self.frames["PageOne"] = PageOne(parent=container, controller=self)
self.frames["PageTwo"] = PageTwo(parent=container, controller=self)
self.frames["StartPage"].grid(row=0, column=0, sticky="nsew")
self.frames["PageOne"].grid(row=0, column=0, sticky="nsew")
self.frames["PageTwo"].grid(row=0, column=0, sticky="nsew")
Over time people have asked other questions using this code (or an online tutorial that copied this code) as a starting point. You might want to read the answers to these questions:
Something like the following should result in each data frame as a separate element in a single list:
temp = list.files(pattern="*.csv")
myfiles = lapply(temp, read.delim)
This assumes that you have those CSVs in a single directory--your current working directory--and that all of them have the lower-case extension .csv
.
If you then want to combine those data frames into a single data frame, see the solutions in other answers using things like do.call(rbind,...)
, dplyr::bind_rows()
or data.table::rbindlist()
.
If you really want each data frame in a separate object, even though that's often inadvisable, you could do the following with assign
:
temp = list.files(pattern="*.csv")
for (i in 1:length(temp)) assign(temp[i], read.csv(temp[i]))
Or, without assign
, and to demonstrate (1) how the file name can be cleaned up and (2) show how to use list2env
, you can try the following:
temp = list.files(pattern="*.csv")
list2env(
lapply(setNames(temp, make.names(gsub("*.csv$", "", temp))),
read.csv), envir = .GlobalEnv)
But again, it's often better to leave them in a single list.
A String
instance allocates a certain amount of bytes in memory. Maybe you're looking at something like sizeof("Hello World")
which would return the number of bytes allocated by the datastructure itself?
In Java, there's usually no need for a sizeof
function, because we never allocate memory to store a data structure. We can have a look at the String.java
file for a rough estimation, and we see some 'int', some references and a char[]
. The Java language specification defines, that a char
ranges from 0 to 65535, so two bytes are sufficient to keep a single char in memory. But a JVM does not have to store one char in 2 bytes, it only has to guarantee, that the implementation of char
can hold values of the defines range.
So sizeof
really does not make any sense in Java. But, assuming that we have a large String and one char
allocates two bytes, then the memory footprint of a String
object is at least 2 * str.length()
in bytes.
For me this error was solved by ensuring the app containing the tasks was included under django's INSTALLED_APPS setting.
I solved the Access-Control-Allow-Origin error modifying the dataType parameter to dataType:'jsonp' and adding a crossDomain:true
$.ajax({
url: 'https://www.googleapis.com/moderator/v1/series?key='+key,
data: myData,
type: 'GET',
crossDomain: true,
dataType: 'jsonp',
success: function() { alert("Success"); },
error: function() { alert('Failed!'); },
beforeSend: setHeader
});
As has been said, they are the same. There are two because bool is a C# keyword and Boolean a .Net class.
You can use sum()
with a generator expression here. The generator expression will be [1, 1, ...]
up to the length of the file. Then we call sum()
to add them all together, to get the total count.
with open('text.txt') as myfile:
count = sum(1 for line in myfile)
It seems by what you have tried that you don't want to include empty lines. You can then do:
with open('text.txt') as myfile:
count = sum(1 for line in myfile if line.rstrip('\n'))
You need to add z-index
to the divs, with a positive number for the top div and negative for the div below
You need to write() the read() data into the new file:
ssize_t nrd;
int fd;
int fd1;
fd = open(aa[1], O_RDONLY);
fd1 = open(aa[2], O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
while (nrd = read(fd,buffer,50)) {
write(fd1,buffer,nrd);
}
close(fd);
close(fd1);
Update: added the proper opens...
Btw, the O_CREAT can be OR'd (O_CREAT | O_WRONLY). You are actually opening too many file handles. Just do the open once.
Use @JsonValue:
public class User {
int id;
String name;
@JsonValue
public int getId() {
return id;
}
}
@JsonValue only works on methods so you must add the getId method. You should be able to skip your custom serializer altogether.
As Michael Borgwardt writes in his answer here:
int diffInDays = (int)( (newerDate.getTime() - olderDate.getTime()) / (1000 * 60 * 60 * 24) )
Note that this works with UTC dates, so the difference may be a day off if you look at local dates. And getting it to work correctly with local dates requires a completely different approach due to daylight savings time.
First off, you shouldn't add $
when you're outside of strings ($class
in your first function being an exception), so it should be:
def doCopyMibArtefactsHere(projectName) {
step ([
$class: 'CopyArtifact',
projectName: projectName,
filter: '**/**.mib',
fingerprintArtifacts: true,
flatten: true
]);
}
def BuildAndCopyMibsHere(projectName, params) {
build job: project, parameters: params
doCopyMibArtefactsHere(projectName)
}
...
Now, as for your problem; the second function takes two arguments while you're only supplying one argument at the call. Either you have to supply two arguments at the call:
...
node {
stage('Prepare Mib'){
BuildAndCopyMibsHere('project1', null)
}
}
... or you need to add a default value to the functions' second argument:
def BuildAndCopyMibsHere(projectName, params = null) {
build job: project, parameters: params
doCopyMibArtefactsHere($projectName)
}
you can also use es6-enum package (https://www.npmjs.com/package/es6-enum). It's very easy to use. See the example below:
import Enum from "es6-enum";
const Colors = Enum("red", "blue", "green");
Colors.red; // Symbol(red)
Centos 7 with PHP7.2:
sudo yum --enablerepo=remi-php72 install php-pecl-zip
It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILE
would have been too narrow in its meaning.
import Foundation
extension CGFloat {
var string1: String {
return String(format: "%.1f", self)
}
var string2: String {
return String(format: "%.2f", self)
}
}
let offset = CGPoint(1.23, 4.56)
print("offset: \(offset.x.string1) x \(offset.y.string1)")
// offset: 1.2 x 4.6
or perhaps:
from glob import glob
...
for files in glob('path/*.mp3'):
do something
for files in glob('path/*.flac'):
do something else
Take care of performance:
I experienced that at least with EF Core the different answers given here might result in different performance. I'm aware that the OP asked about Linq to SQL, but it seems to me that the same questions occur also with EF Core.
In a specific case I had to handle, the (syntactically nicer) suggestion by Marc Gravell resulted in left joins inside a cross apply -- similarly to what Mike U described -- which had the result that the estimated costs for this specific query were two times as high compared to a query with no cross joins. The server execution times differed by a factor of 3. [1]
The solution by Marc Gravell resulted in a query without cross joins.
Context: I essentially needed to perform two left joins on two tables each of which again required a join to another table. Furthermore, there I had to specify other where-conditions on the tables on which I needed to apply the left join. In addition, I had two inner joins on the main table.
Estimated operator costs:
Server execution times in ms (queries executed 10 times; measured using SET STATISTICS TIME ON):
(The very first run was slower for both queries; seems that something is cached.)
Table sizes:
EF Core version: 2.2.1.
SQL Server version: MS SQL Server 2017 - 14... (on Windows 10).
All relevant tables had indexes on the primary keys only.
My conclusion: it's always recommended to look at the generated SQL since it can really differ.
[1] Interestingly enough, when setting the 'Client statistics' in MS SQL Server Management Studio on, I could see an opposite trend; namely that last run of the solution without cross apply took more than 1s. I suppose that something was going wrong here - maybe with my setup.
Just use event.getSource()
frim within actionPerformed
Cast it to the component
for Ex, if you need combobox
JComboBox comboBox = (JComboBox) event.getSource();
JTextField txtField = (JTextField) event.getSource();
use appropriate api to get the value,
for Ex.
Object selected = comboBox.getSelectedItem(); etc.
The default display
property for a table is display:table;
. The only other useful value is inline-table
. All other display
values are invalid for table elements.
There isn't an auto
option to reset it to default, although if you're working in Javascript, you can set it to an empty string, which will do the trick.
width:auto;
is valid, but isn't the default. The default width for a table is 100%
, whereas width:auto;
will make the element only take up as much width as it needs to.
min-width:auto;
isn't allowed. If you set min-width
, it must have a value, but setting it to zero is probably as good as resetting it to default.
Maybe easy like this?
Compiled binaries of the PHP interpreter can be found at http://www.mamp.info/en/ downloads/index.html . Drop this downloaded folder into your /Applications/MAMP/bin/php! directory. Close and re-open your MAMP PRO application. Your new PHP version should now appear in the PHP drop down menu. MAMP PRO will only support PHP versions from the downloads page.
git remote show origin
Replace 'origin' with whatever the name of your remote is.
You could just change ABI to use older builds:
defaultConfig {
...
ndk {
abiFilters 'armeabi-v7a'
}
...
}
You should also use deprecated NDK by adding this line to gradle.properties
:

JQUery has a .parents() method for moving up the DOM tree you can start there.
If you're interested in doing this a more semantic way I don't think using the REL attribute on a button is the best way to semantically define "this is the answer" in your code. I'd recommend something along these lines:
<p id="question1">
<label for="input1">Volume =</label>
<input type="text" name="userInput1" id="userInput1" />
<button type="button">Check answer</button>
<input type="hidden" id="answer1" name="answer1" value="3.93e-6" />
</p>
and
$("button").click(function () {
var correctAnswer = $(this).parent().siblings("input[type=hidden]").val();
var userAnswer = $(this).parent().siblings("input[type=text]").val();
validate(userAnswer, correctAnswer);
$("#messages").html(feedback);
});
Not quite sure how your validate and feedback are working, but you get the idea.
if (!System.IO.File.Exists(filePath))
return SomeHelper.EmptyImageResult(); // preventing JSON GET/POST exception
else
return new FilePathResult(filePath, contentType);
SomeHelper.EmptyImageResult()
should return FileResult
with existing image (1x1 transparent, for example).
This is easiest way if you have files stored on local drive.
If files are byte[]
or stream
- then use FileContentResult
or FileStreamResult
as Dylan suggested.
"Sleep" state connections are most often created by code that maintains persistent connections to the database.
This could include either connection pools created by application frameworks, or client-side database administration tools.
As mentioned above in the comments, there is really no reason to worry about these connections... unless of course you have no idea where the connection is coming from.
(CAVEAT: If you had a long list of these kinds of connections, there might be a danger of running out of simultaneous connections.)
This appears to be a UTF-8 encoding issue that may have been caused by a double-UTF8-encoding of the database file contents.
This situation could happen due to factors such as the character set that was or was not selected (for instance when a database backup file was created) and the file format and encoding database file was saved with.
I have seen these strange UTF-8 characters in the following scenario (the description may not be entirely accurate as I no longer have access to the database in question):
Looking into the file contents:
So, the issue is that "false" (UTF8-encoded twice) utf-8 needs to be converted back into "correct" utf-8 (only UTF8-encoded once).
Trying to fix this in PHP turns out to be a bit challenging:
utf8_decode() is not able to process the characters.
// Fails silently (as in - nothing is output)
$str = "så";
$str = utf8_decode($str);
printf("\n%s", $str);
$str = utf8_decode($str);
printf("\n%s", $str);
iconv() fails with "Notice: iconv(): Detected an illegal character in input string".
echo iconv("UTF-8", "ISO-8859-1", "så");
Another fine and possible solution fails silently too in this scenario
$str = "så";
echo html_entity_decode(htmlentities($str, ENT_QUOTES, 'UTF-8'), ENT_QUOTES , 'ISO-8859-15');
mb_convert_encoding() silently: #
$str = "så";
echo mb_convert_encoding($str, 'ISO-8859-15', 'UTF-8');
// (No output)
Trying to fix the encoding in MySQL by converting the MySQL database characterset and collation to UTF-8 was unsuccessfully:
ALTER DATABASE myDatabase CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE myTable CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
I see a couple of ways to resolve this issue.
The first is to make a backup with correct encoding (the encoding needs to match the actual database and table encoding). You can verify the encoding by simply opening the resulting SQL file in a text editor.
The other is to replace double-UTF8-encoded characters with single-UTF8-encoded characters. This can be done manually in a text editor. To assist in this process, you can manually pick incorrect characters from Try UTF-8 Encoding Debugging Chart (it may be a matter of replacing 5-10 errors).
Finally, a script can assist in the process:
$str = "så";
// The two arrays can also be generated by double-encoding values in the first array and single-encoding values in the second array.
$str = str_replace(["Ã","Â¥"], ["Ã","¥"], $str);
$str = utf8_decode($str);
echo $str;
// Output: "så" (correct)
this works for me
new_df = df[df.loc[:]!=0].dropna()
Use this one, it is trusted solution and works well for all browsers:
protected void clearInput(WebElement webElement) {
// isIE() - just checks is it IE or not - use your own implementation
if (isIE() && "file".equals(webElement.getAttribute("type"))) {
// workaround
// if IE and input's type is file - do not try to clear it.
// If you send:
// - empty string - it will find file by empty path
// - backspace char - it will process like a non-visible char
// In both cases it will throw a bug.
//
// Just replace it with new value when it is need to.
} else {
// if you have no StringUtils in project, check value still empty yet
while (!StringUtils.isEmpty(webElement.getAttribute("value"))) {
// "\u0008" - is backspace char
webElement.sendKeys("\u0008");
}
}
}
If input has type="file" - do not clear it for IE. It will try to find file by empty path and will throw a bug.

One of the dummies ways to determine if .NET Core
is installed on Windows is:
cmd
dotnet --version
If the .NET Core
is installed, we should not get any error in the above steps.
According to Javax's persistence documentation:
Whether the column is included in SQL UPDATE statements generated by the persistence provider.
It would be best to understand from the official documentation here.
Other method by using pandas
import pandas as pd
LIST = ["a","a","c","a","a","v","d"]
counts,values = pd.Series(LIST).value_counts().values, pd.Series(LIST).value_counts().index
df_results = pd.DataFrame(list(zip(values,counts)),columns=["value","count"])
You can then export results in any format you want
Justin has correctly shown the expansion in the case where the join is just followed by a select
. If you've got something else, it becomes more tricky due to transparent identifiers - the mechanism the C# compiler uses to propagate the scope of both halves of the join.
So to change Justin's example slightly:
var result = from sc in enumerableOfSomeClass
join soc in enumerableOfSomeOtherClass
on sc.Property1 equals soc.Property2
where sc.X + sc.Y == 10
select new { SomeClass = sc, SomeOtherClass = soc }
would be converted into something like this:
var result = enumerableOfSomeClass
.Join(enumerableOfSomeOtherClass,
sc => sc.Property1,
soc => soc.Property2,
(sc, soc) => new { sc, soc })
.Where(z => z.sc.X + z.sc.Y == 10)
.Select(z => new { SomeClass = z.sc, SomeOtherClass = z.soc });
The z
here is the transparent identifier - but because it's transparent, you can't see it in the original query :)
If you want to run the script directly, you can:

(Three years late...) but I believe the answer to your second question is that SSRS essentially treats data from your datasets as unsorted; I'm not sure if it ignores any ORDER BY in the sql, or if it just assumes the data is unsorted.
To sort your groups in a particular order, you need to specify it in the report:
For the report I just created, the default sort order on the category was alphabetic on the category group which was basically a string code. But sometimes it can be useful to sort by some other characteristic of the data; for example, my report is of Average and Maximum processing times for messages identified by some code (the category). By setting the sort order of the group to be on [MaxElapsedMs], Z->A it draws my attention to the worst-performing message-types.
This sort of presentation won't be useful for every report but it can be an excellent tool to guide readers to have a better understanding of the data; though on other occasions you might prefer a report to have the same ordering every time it runs, in which case sorting on the category label itself may be best... and I guess there are circumstances where changing the sort order could harm understanding, such as if the categories implied some sort of ordering (such as date values?)
You can use the click
event and call your function or move your logic into the handler:
$("#bfCaptchaEntry").click(function(){ myFunction(); });
You can use the click
event and set your function as the handler:
$("#bfCaptchaEntry").click(myFunction);
.click()
Bind an event handler to the "click" JavaScript event, or trigger that event on an element.
You can use the on
event bound to "click"
and call your function or move your logic into the handler:
$("#bfCaptchaEntry").on("click", function(){ myFunction(); });
You can use the on
event bound to "click"
and set your function as the handler:
$("#bfCaptchaEntry").on("click", myFunction);
.on()
Attach an event handler function for one or more events to the selected elements.
string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_');
Alternatively, to change all characters except numbers and letters, try:
string = string.replace(/[^a-zA-Z0-9]/g,'_');
A good way to check whether a python object is an instance of a type is to use isinstance()
which is Python's 'built-in' function.
For Python 3.6:
dct = {
"1": "a",
"3": "b",
"8": {
"12": "c",
"25": "d"
}
}
for key in dct.keys():
if isinstance(dct[key], dict)== False:
print(key, dct[key])
#shows:
# 1 a
# 3 b
implode
or join
(they're the exact same thing) would work here. Alternatively, you can just call array_pop
and get the value of the only element in the array.
This is a common function of Adorners in WPF. Adorners typically appear above all other controls, but the other answers that mention z-order may fit your case better.
The most important thing to know is that ES6 modules are, indeed, an official standard, while CommonJS (Node.js) modules are not.
In 2019, ES6 modules are supported by 84% of browsers. While Node.js puts them behind an --experimental-modules flag, there is also a convenient node package called esm, which makes the integration smooth.
Another issue you're likely to run into between these module systems is code location. Node.js assumes source is kept in a node_modules
directory, while most ES6 modules are deployed in a flat directory structure. These are not easy to reconcile, but it can be done by hacking your package.json
file with pre and post installation scripts. Here is an example isomorphic module and an article explaining how it works.
Try this one Open your projectname.csproj file its work for me.
<PackageReference Include="System.Data.SqlClient" Version="4.6.0" />
You need to add this Reference "ItemGroup" tag inside.
You could can use git rebase
to rewrite the commit history. This can be potentially destructive to your changes, so use with care.
First commit your "amend" change as a normal commit. Then do an interactive rebase starting on the parent of your oldest commit
git rebase -i 47175e84c2cb7e47520f7dde824718eae3624550^
This will fire up your editor with all commits. Reorder them so your "amend" commit comes below the one you want to amend. Then replace the first word on the line with the "amend" commit with s
which will combine (s quash) it with the commit before. Save and exit your editor and follow the instructions.
I`m very happy my problem is solved.
and do this : Look below that line and find the tag. It will have a big ol' select statement in it. Remove the tag and it's contents..
now without changing DB T I can insert to a table which has not PK
thanks all and thank Pharylon
For python 3 and above
s = raw_input()
it will solve the problem on pycharm IDE if you are solving on online site exactly hackerrank then use:
s = input()
The easiest is to put overflow:hidden
on the parent div and don't specify a height:
#parent { overflow: hidden }
Another way is to also float the parent div:
#parent { float: left; width: 100% }
Another way uses a clear element:
<div class="parent">
<img class="floated_child" src="..." />
<span class="clear"></span>
</div>
CSS
span.clear { clear: left; display: block; }
If you want to get the stdout AND know whether the command succeeded or not, just use returnStdout
and wrap it in an exception handler:
scripted pipeline
try {
// Fails with non-zero exit if dir1 does not exist
def dir1 = sh(script:'ls -la dir1', returnStdout:true).trim()
} catch (Exception ex) {
println("Unable to read dir1: ${ex}")
}
output:
[Pipeline] sh
[Test-Pipeline] Running shell script
+ ls -la dir1
ls: cannot access dir1: No such file or directory
[Pipeline] echo
unable to read dir1: hudson.AbortException: script returned exit code 2
Unfortunately hudson.AbortException is missing any useful method to obtain that exit status, so if the actual value is required you'd need to parse it out of the message (ugh!)
Contrary to the Javadoc https://javadoc.jenkins-ci.org/hudson/AbortException.html the build is not failed when this exception is caught. It fails when it's not caught!
Update: If you also want the STDERR output from the shell command, Jenkins unfortunately fails to properly support that common use-case. A 2017 ticket JENKINS-44930 is stuck in a state of opinionated ping-pong whilst making no progress towards a solution - please consider adding your upvote to it.
As to a solution now, there could be a couple of possible approaches:
a) Redirect STDERR to STDOUT 2>&1
- but it's then up to you to parse that out of the main output though, and you won't get the output if the command failed - because you're in the exception handler.
b) redirect STDERR to a temporary file (the name of which you prepare earlier) 2>filename
(but remember to clean up the file afterwards) - ie. main code becomes:
def stderrfile = 'stderr.out'
try {
def dir1 = sh(script:"ls -la dir1 2>${stderrfile}", returnStdout:true).trim()
} catch (Exception ex) {
def errmsg = readFile(stderrfile)
println("Unable to read dir1: ${ex} - ${errmsg}")
}
c) Go the other way, set returnStatus=true
instead, dispense with the exception handler and always capture output to a file, ie:
def outfile = 'stdout.out'
def status = sh(script:"ls -la dir1 >${outfile} 2>&1", returnStatus:true)
def output = readFile(outfile).trim()
if (status == 0) {
// output is directory listing from stdout
} else {
// output is error message from stderr
}
Caveat: the above code is Unix/Linux-specific - Windows requires completely different shell commands.
From the documentation (MySQL 8) :
Type | Maximum length -----------+------------------------------------- TINYTEXT | 255 (2 8−1) bytes TEXT | 65,535 (216−1) bytes = 64 KiB MEDIUMTEXT | 16,777,215 (224−1) bytes = 16 MiB LONGTEXT | 4,294,967,295 (232−1) bytes = 4 GiB
Note that the number of characters that can be stored in your column will depend on the character encoding.
You can use ngHide (or ngShow) directive. It doesn't create child scope as ngIf does.
<div ng-hide="testa">
You can as well use $.when()
to wait until the promise
finished:
var myEvent = function() {
$( selector ).fadeOut( 'fast' );
};
$.when( myEvent() ).done( function() {
console.log( 'Task finished.' );
} );
In case you're doing a request that could as well fail, then you can even go one step further:
$.when( myEvent() )
.done( function( d ) {
console.log( d, 'Task done.' );
} )
.fail( function( err ) {
console.log( err, 'Task failed.' );
} )
// Runs always
.then( function( data, textStatus, jqXHR ) {
console.log( jqXHR.status, textStatus, 'Status 200/"OK"?' );
} );
You have to rely on '#' but to make the task easier in vi you can perform the following (press escape first):
:10,20 s/^/#
with 10 and 20 being the start and end line numbers of the lines you want to comment out
and to undo when you are complete:
:10,20 s/^#//

How we do it is put this method into a class and then call the class from the view
@Html.DropDownListFor(x => x.State, Class.States)
A variation using just standard color code:
android:textColor="#ff0000"
Using jQuery:
$('td:contains("male")')
Another way of doing the same thing:
class bol(object):
def __init__(self, f):
self.f = f
def __call__(self):
return "<b>{}</b>".format(self.f())
class ita(object):
def __init__(self, f):
self.f = f
def __call__(self):
return "<i>{}</i>".format(self.f())
@bol
@ita
def sayhi():
return 'hi'
Or, more flexibly:
class sty(object):
def __init__(self, tag):
self.tag = tag
def __call__(self, f):
def newf():
return "<{tag}>{res}</{tag}>".format(res=f(), tag=self.tag)
return newf
@sty('b')
@sty('i')
def sayhi():
return 'hi'
I was not able to copy Jenkins job from subfolder. copy from
option did not show the suggestion which i was looking for.Without using suggestion copying the job name didn't work.
So if you want to create a job from outer folder, you need to first create the job in subfolder and then move it in different folder where you need to place it.
You need the line
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
Because the default behaviour for the JFrame when you press the X button is the equivalent to
frame.setDefaultCloseOperation(WindowConstants.HIDE_ON_CLOSE);
So almost all the times you'll need to add that line manually when creating your JFrame
I am currently referring to constants in WindowConstants
like WindowConstants.EXIT_ON_CLOSE
instead of the same constants declared directly in JFrame
as the prior reflect better the intent.

Events are pretty easy in C#, but the MSDN docs in my opinion make them pretty confusing. Normally, most documentation you see discusses making a class inherit from the EventArgs
base class and there's a reason for that. However, it's not the simplest way to make events, and for someone wanting something quick and easy, and in a time crunch, using the Action
type is your ticket.
1. Create your event on your class right after your class
declaration.
public event Action<string,string,string,string>MyEvent;
2. Create your event handler class method in your class.
private void MyEventHandler(string s1,string s2,string s3,string s4)
{
Console.WriteLine("{0} {1} {2} {3}",s1,s2,s3,s4);
}
3. Now when your class is invoked, tell it to connect the event to your new event handler. The reason the +=
operator is used is because you are appending your particular event handler to the event. You can actually do this with multiple separate event handlers, and when an event is raised, each event handler will operate in the sequence in which you added them.
class Example
{
public Example() // I'm a C# style class constructor
{
MyEvent += new Action<string,string,string,string>(MyEventHandler);
}
}
4. Now, when you're ready, trigger (aka raise) the event somewhere in your class code like so:
MyEvent("wow","this","is","cool");
The end result when you run this is that the console will emit "wow this is cool". And if you changed "cool" with a date or a sequence, and ran this event trigger multiple times, you'd see the result come out in a FIFO sequence like events should normally operate.
In this example, I passed 4 strings. But you could change those to any kind of acceptable type, or used more or less types, or even remove the <...>
out and pass nothing to your event handler.
And, again, if you had multiple custom event handlers, and subscribed them all to your event with the +=
operator, then your event trigger would have called them all in sequence.
But what if you want to identify the caller to this event in your event handler? This is useful if you want an event handler that reacts with conditions based on who's raised/triggered the event. There are a few ways to do this. Below are examples that are shown in order by how fast they operate:
Option 1. (Fastest) If you already know it, then pass the name as a literal string to the event handler when you trigger it.
Option 2. (Somewhat Fast) Add this into your class and call it from the calling method, and then pass that string to the event handler when you trigger it:
private static string GetCaller([System.Runtime.CompilerServices.CallerMemberName] string s = null) => s;
Option 3. (Least Fast But Still Fast) In your event handler when you trigger it, get the calling method name string with this:
string callingMethod = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().ReflectedType.Name.Split('<', '>')[1];
You may have a scenario where your custom event has multiple event handlers, but you want to remove one special one out of the list of event handlers. To do so, use the -=
operator like so:
MyEvent -= MyEventHandler;
A word of minor caution with this, however. If you do this and that event no longer has any event handlers, and you trigger that event again, it will throw an exception. (Exceptions, of course, you can trap with try/catch blocks.)
Okay, let's say you're through with events and you don't want to process any more. Just set it to null like so:
MyEvent = null;
The same caution for Unsubscribing events is here, as well. If your custom event handler no longer has any events, and you trigger it again, your program will throw an exception.
T-SQL supports only AFTER and INSTEAD OF triggers, it does not feature a BEFORE trigger, as found in some other RDBMSs.
I believe you will want to use an INSTEAD OF trigger.
Here is my solution, i have been reading a lot of post and they was really helpfull, finaly i build a code for small files, with cUrl and Php, that i think its really usefull.
public function postFile()
{
$file_url = "test.txt"; //here is the file route, in this case is on same directory but you can set URL too like "http://examplewebsite.com/test.txt"
$eol = "\r\n"; //default line-break for mime type
$BOUNDARY = md5(time()); //random boundaryid, is a separator for each param on my post curl function
$BODY=""; //init my curl body
$BODY.= '--'.$BOUNDARY. $eol; //start param header
$BODY .= 'Content-Disposition: form-data; name="sometext"' . $eol . $eol; // last Content with 2 $eol, in this case is only 1 content.
$BODY .= "Some Data" . $eol;//param data in this case is a simple post data and 1 $eol for the end of the data
$BODY.= '--'.$BOUNDARY. $eol; // start 2nd param,
$BODY.= 'Content-Disposition: form-data; name="somefile"; filename="test.txt"'. $eol ; //first Content data for post file, remember you only put 1 when you are going to add more Contents, and 2 on the last, to close the Content Instance
$BODY.= 'Content-Type: application/octet-stream' . $eol; //Same before row
$BODY.= 'Content-Transfer-Encoding: base64' . $eol . $eol; // we put the last Content and 2 $eol,
$BODY.= chunk_split(base64_encode(file_get_contents($file_url))) . $eol; // we write the Base64 File Content and the $eol to finish the data,
$BODY.= '--'.$BOUNDARY .'--' . $eol. $eol; // we close the param and the post width "--" and 2 $eol at the end of our boundary header.
$ch = curl_init(); //init curl
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'X_PARAM_TOKEN : 71e2cb8b-42b7-4bf0-b2e8-53fbd2f578f9' //custom header for my api validation you can get it from $_SERVER["HTTP_X_PARAM_TOKEN"] variable
,"Content-Type: multipart/form-data; boundary=".$BOUNDARY) //setting our mime type for make it work on $_FILE variable
);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/1.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0'); //setting our user agent
curl_setopt($ch, CURLOPT_URL, "api.endpoint.post"); //setting our api post url
curl_setopt($ch, CURLOPT_COOKIEJAR, $BOUNDARY.'.txt'); //saving cookies just in case we want
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); // call return content
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); navigate the endpoint
curl_setopt($ch, CURLOPT_POST, true); //set as post
curl_setopt($ch, CURLOPT_POSTFIELDS, $BODY); // set our $BODY
$response = curl_exec($ch); // start curl navigation
print_r($response); //print response
}
With this we shoud be get on the "api.endpoint.post" the following vars posted You can easly test with this script, and you should be recive this debugs on the function postFile() at the last row
print_r($response); //print response
public function getPostFile()
{
echo "\n\n_SERVER\n";
echo "<pre>";
print_r($_SERVER['HTTP_X_PARAM_TOKEN']);
echo "/<pre>";
echo "_POST\n";
echo "<pre>";
print_r($_POST['sometext']);
echo "/<pre>";
echo "_FILES\n";
echo "<pre>";
print_r($_FILEST['somefile']);
echo "/<pre>";
}
Here you are it should be work good, could be better solutions but this works and is really helpfull to understand how the Boundary and multipart/from-data mime works on php and curl library,
My Best Reggards,

You can use 'input' event, that occurs when an element gets user input.
$(document).on('input', '#input_id', function() {
// this will fire all possible change actions
});
documentation from w3
Here it is:
function call_func(input) {
var evaled = eval('(' + input + ')');
var newDiv = document.createElement('div');
var id = evaled.id;
var name = evaled.Student_name;
var dob = evaled.student_dob;
var html = '<b>ID:</b>';
html += '<a href="/learningyii/index.php?r=student/view& id=' + id + '">' + id + '</a>';
html += '<br/>';
html += '<b>Student Name:</b>';
html += name;
html += '<br/>';
html += '<b>Student DOB:</b>';
html += dob;
html += '<br/>';
newDiv.innerHTML = html;
newDiv.setAttribute('class', 'view');
$('#StudentGridViewId').find('.items').prepend(newDiv);
};
For Notepad++ 64-bit:
There is an unreleased 64-bit version of this plugin. You can download the DLL from here, drop it under Notepad++/plugins/NppTextFX directory and restart Notepad++. You will need to create the NppTextFX directory first though.
As per this GitHub issue, there might be some bugs lurking around. If you run into any, feel free to raise a GitHub ticket for each, as the author (HQJaTu) is recommending. As per the author, the code behind this binary is found on this branch.
Tested on Notepad++ v7.5.8 (64-bit, Build time: Jul 23 2018)
In terms of the type of shift you get, the important thing is the type of the value that you're shifting. A classic source of bugs is when you shift a literal to, say, mask off bits. For example, if you wanted to drop the left-most bit of an unsigned integer, then you might try this as your mask:
~0 >> 1
Unfortunately, this will get you into trouble because the mask will have all of its bits set because the value being shifted (~0) is signed, thus an arithmetic shift is performed. Instead, you'd want to force a logical shift by explicitly declaring the value as unsigned, i.e. by doing something like this:
~0U >> 1;
For xml parsing of an inputstream you can do:
// the SAX way:
XMLReader myReader = XMLReaderFactory.createXMLReader();
myReader.setContentHandler(handler);
myReader.parse(new InputSource(new URL(url).openStream()));
// or if you prefer DOM:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new URL(url).openStream());
But to communicate over http from server to client I prefer using hessian library or springs http invoker lib
I think this may the most easy way to finish this work:

from pandas import DataFrame
from statsmodels.api import OLS
lr = lambda : [random() for i in range(100)]
x = DataFrame({'x1': lr(), 'x2':lr(), 'x3':lr()})
