This is called string interpolation; it doesn't exist as such in Java.
One approach is to use String.format:
String string = String.format("A string %s", aVariable);
Another approach is to use a templating library such as Velocity or FreeMarker.
REASON
This happens because for now they only ship 64bit JRE with Android Studio for Windows which produces glitches in 32 bit systems.
SOLUTION
For more details: https://code.google.com/p/android/issues/detail?id=219524
You have several options to set up variables from outside your makefile:
From environment - each environment variable is transformed into a makefile variable with the same name and value.
You may also want to set -e
option (aka --environments-override
) on, and your environment variables will override assignments made into makefile (unless these assignments themselves use the override
directive . However, it's not recommended, and it's much better and flexible to use ?=
assignment (the conditional variable assignment operator, it only has an effect if the variable is not yet defined):
FOO?=default_value_if_not_set_in_environment
Note that certain variables are not inherited from environment:
MAKE
is gotten from name of the scriptSHELL
is either set within a makefile, or defaults to /bin/sh
(rationale: commands are specified within the makefile, and they're shell-specific).From command line - make
can take variable assignments as part of his command line, mingled with targets:
make target FOO=bar
But then all assignments to FOO
variable within the makefile will be ignored unless you use the override
directive in assignment. (The effect is the same as with -e
option for environment variables).
Exporting from the parent Make - if you call Make from a Makefile, you usually shouldn't explicitly write variable assignments like this:
# Don't do this!
target:
$(MAKE) -C target CC=$(CC) CFLAGS=$(CFLAGS)
Instead, better solution might be to export these variables. Exporting a variable makes it into the environment of every shell invocation, and Make calls from these commands pick these environment variable as specified above.
# Do like this
CFLAGS=-g
export CFLAGS
target:
$(MAKE) -C target
You can also export all variables by using export
without arguments.
Run the code either in onload event, either just before you close body
tag.
You try to find an element wich is not there at the moment you do it.
<?php
$xml = $argv[1];
$dom = new DOMDocument();
// Initial block (must before load xml string)
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
// End initial block
$dom->loadXML($xml);
$out = $dom->saveXML();
print_R($out);
Found the solution as below.... posting it as it could help somebody else too :)
DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = format.parse("2014-04-24 11:15:00");
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(date);
XMLGregorianCalendar xmlGregCal = DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);
System.out.println(xmlGregCal);
Output:
2014-04-24T11:15:00.000+02:00
$("#birthdate" ).datepicker("setDate", new Date(1985,01,01))
I've opted for a quick Polyfill based on the above answers:
//# Polyfill
window.addEventListener = window.addEventListener || function (e, f) { window.attachEvent('on' + e, f); };
//# Standard usage
window.addEventListener("message", function(){ /*...*/ }, false);
Of course, like the answers above this doesn't ensure that window.attachEvent
exists, which may or may not be an issue.
Jeff Gilfelt's answer as a static helper method:
private static String getSizeName(Context context) {
int screenLayout = context.getResources().getConfiguration().screenLayout;
screenLayout &= Configuration.SCREENLAYOUT_SIZE_MASK;
switch (screenLayout) {
case Configuration.SCREENLAYOUT_SIZE_SMALL:
return "small";
case Configuration.SCREENLAYOUT_SIZE_NORMAL:
return "normal";
case Configuration.SCREENLAYOUT_SIZE_LARGE:
return "large";
case 4: // Configuration.SCREENLAYOUT_SIZE_XLARGE is API >= 9
return "xlarge";
default:
return "undefined";
}
}
step 1 : create layout with name activity_main.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/rl"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp"
tools:context=".MainActivity"
android:background="#c6cabd"
>
<TextView
android:id="@+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="17dp"
android:textColor="#ff0e13"
/>
<EditText
android:id="@+id/et"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/tv"
android:hint="Input your country"

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get EditText Text"
android:layout_below="@id/et"
/>
</RelativeLayout>
Step 2 : Create class Main.class
public class Main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.btn);
final TextView tv = (TextView) findViewById(R.id.tv);
final EditText et = (EditText) findViewById(R.id.et);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String country = et.getText().toString();
tv.setText("Your inputted country is : " + country);
}
});
}
}

int itag = 22;
// Here you can get download url
String downloadUrl = ytFiles.get(itag).getUrl();
}
}
};
ytEx.execute(youtubeLink);
This question has been asked and answered many times:
Read file from serial port using Java
Reading file from serial port in Java
Is there Java library or framework for accessing Serial ports?
Java Serial Communication on Windows
to reference a few.
Personally I recommend SerialPort from http://serialio.com - it's not free, but it's well worth the developer (no royalties) licensing fee for any commercial project. Sadly, it is no longer royalty free to deploy, and SerialIO.com seems to have remade themselves as a hardware seller; I had to search for information on SerialPort.
From personal experience, I strongly recommend against the Sun, IBM and RxTx implementations, all of which were unstable in 24/7 use. Refer to my answers on some of the aforementioned questions for details. To be perfectly fair, RxTx may have come a long way since I tried it, though the Sun and IBM implementations were essentially abandoned, even back then.
A newer free option that looks promising and may be worth trying is jSSC (Java Simple Serial Connector), as suggested by @Jodes comment.
Short tag are alwayes available in php. So you do not need echo the first statement in your script
example:
$a =10;
<?= $a;//10
echo "Hellow";//
echo "Hellow";
?>
Suddenly you need to use for a single php script then u can use it. example:
<html>
<head>
<title></title>
</head>
<body>
<p>hellow everybody<?= hi;?></p>
<p>hellow everybody </p>
<p>hellow everybody </p>
</body>
</html>
Or you can skip rake and use the 'rspec' command:
rspec path/to/spec/file.rb
In your case I think as long as your ./spec/db_spec.rb file includes the appropriate helpers, it should work fine.
If you're using an older version of rspec it is:
spec path/to/spec/file.rb
By using ''.join
list1 = ['1', '2', '3']
str1 = ''.join(list1)
Or if the list is of integers, convert the elements before joining them.
list1 = [1, 2, 3]
str1 = ''.join(str(e) for e in list1)
Do not use Class.newInstance()
; see this thread: Why is Class.newInstance() evil?
Like other answers say, use Constructor.newInstance()
instead.
I had the pleasure of experiencing this random problem in Visual Studio 2017 Enterprise.
I tried every solution here, and it didn't work, including the Visual Studio repair (which takes a while). Several hours in, I thought maybe I should actually check the ActivityLog.xml file.
I uninstalled the offending extension from the 'Developer Command Prompt for VS2017' as an administrator since Visual Studio just freezed after open and nothing could be clicked.
Steps to uninstall - courtesy of jessehouwing.net
vsixinstaller /u:Microsoft.VisualStudio.LiveShare
to remove the extension.If you are using qmake, the standard Qt build system, just add a line to the .pro
file as documented in the qmake Variable Reference:
INCLUDEPATH += <your path>
If you are using your own build system, you create a project by selecting "Import of Makefile-based project". This will create some files in your project directory including a file named <your project name>.includes
. In that file, simply list the paths you want to include, one per line. Really all this does is tell Qt Creator where to look for files to index for auto completion. Your own build system will have to handle the include paths in its own way.
As explained in the Qt Creator Manual, <your path>
must be an absolute path, but you can avoid OS-, host- or user-specific entries in your .pro
file by using $$PWD
which refers to the folder that contains your .pro
file, e.g.
INCLUDEPATH += $$PWD/code/include
You have no need to put for loop to see the data into the array, you can simply do in following manner
<?php
echo "<pre>";
print_r($results);
echo "</pre>";
?>
GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
aspose pdf works pretty well. then again, you have to pay for it
Since Ubuntu 16.04 includes snapd
by default.
So, the easiest way to install the stable version is
$ sudo snap install intellij-idea-community --classic
$ sudo snap install intellij-idea-ultimate --classic
For the latest version use channel --edge
$ sudo snap install intellij-idea-community --classic --edge
Here is the list of all channels https://snapcraft.io/intellij-idea-ultimate (drop down 'All versions').
--classic
The --classic option is required because the IntelliJ IDEA snap requires full access to the system, like a traditionally packaged application.
[https://www.jetbrains.com/help/idea/install-and-set-up-product.html#install-on-linux-with-snaps]
--edge
--edge Install from the edge channel [http://manpages.ubuntu.com/manpages/bionic/man1/snap.1.html]
Note: Snap, also work a few major distributions: Arch, Debian, Fedora, openSUSE, Linux Mint,...
In R you can use the refresh method, but to start with we navigate to a url using navigate method:
remDr$navigate("https://...")
remDr$refresh()
Java is only pass-by-value. (or better - pass-reference-by-value)
So the passed argument and the argument within the method are two different handlers pointing to the same object (value).
Therefore if you change the state of the object, it is reflected to every other variable that's referencing it. But if you re-assign a new object (value) to the argument, then other variables pointing to this object (value) do not get re-assigned.
You can do both in code and XML. Only 4 basic things to be set.
e.g.
android:shadowColor="@color/text_shadow_color"
android:shadowDx="-2"
android:shadowDy="2"
android:shadowRadius="0.01"
This draws a prominent shadow on left-lower side of text. In code, you can add something like this;
TextView item = new TextView(getApplicationContext());
item.setText(R.string.text);
item.setTextColor(getResources().getColor(R.color.general_text_color));
item.setShadowLayer(0.01f, -2, 2, getResources().getColor(R.color.text_shadow_color));
You can use Data::Dump
:
use Data::Dump qw(dump);
my @a = (1, [2, 3], {4 => 5});
dump(@a);
Produces:
"(1, [2, 3], { 4 => 5 })"
The algorithm has 4 simple steps:
Code for the algorithm in python:
def my_sort(A):
p=A[0] #determine pivot element.
left=[] #create left array
right=[] #create right array
for i in range(1,len(A)):
#if cur elem is less than pivot, add elem in left array
if A[i]< p:
left.append(A[i])
#the recurssion will occur only if the left array is atleast half the size of original array
if len(left)>1 and len(left)>=len(A)//2:
left=my_sort(left) #recursive call
elif A[i]>p:
right.append(A[i]) #if elem is greater than pivot, append it to right array
if len(right)>1 and len(right)>=len(A)//2: # recurssion will occur only if length of right array is atleast the size of original array
right=my_sort(right)
A=left+[p]+right #append all three part of the array into one and return it
return A
my_sort([12,4,5,6,7,3,1,15])
Carry on with this algorithm recursively with the left and right parts.
Bootstrap 3 dropped native support for nested collapsing menus, but there's a way to re-enable it with a 3rd party script. It's called SmartMenus. It means adding three new resources to your page, but it seamlessly supports Bootstrap 3.x with multiple levels of menus for nested <ul>/<li>
elements with class="dropdown-menu"
. It automatically displays the proper caret indicator as well.
<head>
...
<script src=".../jquery.smartmenus.min.js"></script>
<script src=".../jquery.smartmenus.bootstrap.min.js"></script>
...
<link rel="stylesheet" href=".../jquery.smartmenus.bootstrap.min.css"/>
...
</head>
Here's a demo page: http://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar-fixed-top.html
def rotate(image, angle, center = None, scale = 1.0):
(h, w) = image.shape[:2]
if center is None:
center = (w / 2, h / 2)
# Perform the rotation
M = cv2.getRotationMatrix2D(center, angle, scale)
rotated = cv2.warpAffine(image, M, (w, h))
return rotated
I had this issue when inserting date data into a database, you can simply use the struct members separately: In my case it's useful since the sql sentence needs to have the right values and you just need to add the slash or dash to complete the format, no conversions needed.
DateTimePicker dtp = new DateTimePicker();
String sql = "insert into table values(" + dtp.Value.Date.Year + "/" +
dtp.Value.Date.Month + "/" + dtp.Value.Date.Day + ");";
That way you get just the date members without time...
First CD to where node(nodejs) is installed using windows CMD, then follow the steps below
C:...\node> git config --system http.sslcainfo /bin/curl-ca-bundle.crt

If you want a CompletableFuture way you could have a method like
public MyResponseObject retrieveDataFromEndpoint() {
CompletableFuture<MyResponseObject> endpointCall
= CompletableFuture.supplyAsync(() ->
yourRestService.callEnpoint(withArg1, withArg2));
try {
return endpointCall.get(10, TimeUnit.MINUTES);
} catch (TimeoutException
| InterruptedException
| ExecutionException e) {
throw new RuntimeException("Unable to fetch data", e);
}
}
If you're using spring, you could annotate the method with a @Retryable
so that it retries the method three times if an exception is thrown.
This will allow a space between the two columns and obviously if you want to change the default width you can go for mixins to modify the default bootstrap width. Or, you can give the width using the inline CSS style.
<div class="col-md-5 pull-left"></div>
<div class="col-md-5 pull-right"></div>
Python 3.3+ has Implicit Namespace Packages that allow it to create a packages without an __init__.py
file.
Allowing implicit namespace packages means that the requirement to provide an
__init__.py
file can be dropped completely, and affected ... .
The old way with __init__.py
files still works as in Python 2.
a is the array of objects you have
a.findIndex(x => x.property=="WhateverPropertyYouWantToMatch") <0 ?
a.push(objectYouWantToPush) : console.log("response if object exists");
Another approach using RegExp
const list = [1, 2, 3, 5, 2, 8, 9, 2]
const d = 2;
const counter = (`${list.join()},`.match(new RegExp(`${d}\\,`, 'g')) || []).length
console.log(counter)

You can't move a mouse but can lock it. Note: that you must call requestPointerLock in click event.
Small Example:
var canvas = document.getElementById('mycanvas');
canvas.requestPointerLock = canvas.requestPointerLock || canvas.mozRequestPointerLock || canvas.webkitRequestPointerLock;
canvas.requestPointerLock();

Here's how to change the dosbox.conf file in Linux to increase the size of the window. I actually DID what follows, so I can say it works (in 32-bit PCLinuxOS fullmontyKDE, anyway). The question's answer is in the .conf file itself.
You find this file in Linux at /home/(username)/.dosbox . In Konqueror or Dolphin, you must first check 'Hidden files' or you won't see the folder. Open it with KWrite superuser or your fav editor.
Then, search on 'output', and as the instruction in the conf file warns, if and only if you have 'hardware scaling', change the default 'output=surface' to something else; he then lists the optional other settings. I changed it to 'output=overlay'. There's one other setting to test: aspect. Search the file for 'aspect', and change the 'false' to 'true' if you want an even bigger window. When I did this, the window took up over half of the screen. With 'false' left alone, I had a somewhat smaller window (I use widescreen monitors, whether laptop or desktop, maybe that's why).
So after you've made the changes, save the file with the original name of dosbox-0.74.conf . Then, type dosbox at the command line or create a Launcher (in KDE, this is a right click on the desktop) with the command dosbox. You still have to go through the mount command (i.e., mount c~ c:\123 if that's the location and file you'll execute). I'm sure there's a way to make a script, but haven't yet learned how to do that.
Yes, the Map
constructor takes an array of key-value pairs.
Object.entries
is a new Object static method available in ES2017 (19.1.2.5).
const map = new Map(Object.entries({foo: 'bar'}));
map.get('foo'); // 'bar'
It's currently implemented in Firefox 46+ and Edge 14+ and newer versions of Chrome
If you need to support older environments and transpilation is not an option for you, use a polyfill, such as the one recommended by georg:
Object.entries = typeof Object.entries === 'function' ? Object.entries : obj => Object.keys(obj).map(k => [k, obj[k]]);
Try this. Click anywhere in your range of data and then use this macro:
Sub CombineColumns()
Dim rng As Range
Dim iCol As Integer
Dim lastCell As Integer
Set rng = ActiveCell.CurrentRegion
lastCell = rng.Columns(1).Rows.Count + 1
For iCol = 2 To rng.Columns.Count
Range(Cells(1, iCol), Cells(rng.Columns(iCol).Rows.Count, iCol)).Cut
ActiveSheet.Paste Destination:=Cells(lastCell, 1)
lastCell = lastCell + rng.Columns(iCol).Rows.Count
Next iCol
End Sub
I have encountered similar (nearly unexplainable) behavior
Found a reference to deleting .exd files under the directory C:\Users\username\AppData\Local\Temp Located one in each of the directory Excel8.0 and VBE. Typical name is MSForms.exd
Google "Excel exd" or "KB 2553154" From my perspective, it is a completely unacceptable situation which has been there for at least a month now.

You can use android:background="#DC143C"
, or any other RGB values for your color. I have no problem using it this way, as stated here
If you have a SOAPMessage
or SOAPMessageContext
, you can use a Transformer
, by converting it to a Source
via DOMSource
:
final SOAPMessage message = messageContext.getMessage();
final StringWriter sw = new StringWriter();
try {
TransformerFactory.newInstance().newTransformer().transform(
new DOMSource(message.getSOAPPart()),
new StreamResult(sw));
} catch (TransformerException e) {
throw new RuntimeException(e);
}
// Now you have the XML as a String:
System.out.println(sw.toString());
This will take the encoding into account, so your "special characters" won't get mangled.
You can use this code instead.

initial: Sets this property to its default value.
inherit Inherits this property from its parent element.
I know the op was using an older version of IIS and this may not apply to him, but I'm posting this as it might help others. I had the same problem and none of the above IPv6 or hosts file changes worked for me. My asp.net MVC4 project was really slow after hitting F5 to refresh js changes on localhost. It was happening across all browsers - Chrome, FF, and IE. Eventually I realised I was running IIS Express 8.0 locally, and it turns out 8.0 is extremely slow when serving up js files and seems to be a bug. If I ran iisexpress on the command line and hit F5 I could see each js file took 4 or 5 seconds to load.
I ended up uninstalling IIS 8.0 and installing IIS express 7.5 and straight away the problem was fixed. Here are the steps I followed:
IIS Express 8.0 seems to be installed with VS 2012 so if you had a new install or possibly a service pack update this might upgrade the previous IIS Express version.
In Windows 7, 8 or 8.1, in Devices Manager:
You can execute this statement in the mysql command line tool:
echo "SELECT concat('ALTER TABLE `',TABLE_NAME,'` ENGINE=InnoDB;')
FROM Information_schema.TABLES
WHERE ENGINE != 'InnoDB' AND TABLE_TYPE='BASE TABLE'
AND TABLE_SCHEMA='name-of-database'" | mysql > convert.sql
You may need to specify username and password using: mysql -u username -p The result is an sql script that you can pipe back into mysql:
mysql name-of-database < convert.sql
Replace "name-of-database" in the above statement and command line.
You can to do it this way:
string Camnr = "", Klantnr = "", ... // or String.Empty
Or you could declare them all first and then in the next line use your way.
This is an old question, but I'm going to add the fix for my particular issue (Spring Boot, JPA using Hibernate, SQL Server 2014) since it doesn't exactly match the other answers included here:
I had a foreign key, e.g. my_id = '12345', but the value in the referenced column was my_id = '12345 '. It had an extra space at the end which hibernate didn't like. I removed the space, fixed the part of my code that was allowing this extra space, and everything works fine.
Note that -regex
depends on whole path.
-regex pattern
File name matches regular expression pattern.
This is a match on the whole path, not a search.
You don't actually have to use -regex
for what you are doing.
find . -iname "*[0-9]"
I don't know anything provided by the Framework (beyond what you want to avoid) that would do what you want but (as I suspect you know) it would be pretty easy to create something simple yourself:
private DataTable GetDataTableFromDGV(DataGridView dgv) {
var dt = new DataTable();
foreach (DataGridViewColumn column in dgv.Columns) {
if (column.Visible) {
// You could potentially name the column based on the DGV column name (beware of dupes)
// or assign a type based on the data type of the data bound to this DGV column.
dt.Columns.Add();
}
}

If you are inserting keys that are comparable but not int-like, you could potentially override the comparison operators on them (i.e. <= become > and > becomes <=). Otherwise, you can override heapq._siftup in the heapq module (it's all just Python code, in the end).
I have scopes for this, hope it help somebody. https://laravel.com/docs/master/eloquent#local-scopes
public function scopeWhereLike($query, $column, $value)
{
return $query->where($column, 'like', '%'.$value.'%');
}
public function scopeOrWhereLike($query, $column, $value)
{
return $query->orWhere($column, 'like', '%'.$value.'%');
}
Usage:
$result = BookingDates::whereLike('email', $email)->orWhereLike('name', $name)->get();
The parseInt solution is the best way to go as it is clear what is happening.
For completeness it is worth mentioning that this can also be done with the + operator
$('.load_more').live("click",function() { //When user clicks
var newcurrentpageTemp = +$(this).attr("id") + 1; //Get the id from the hyperlink
alert(newcurrentpageTemp);
dosomething();
});
In my case problem was in css and html layout.
Layout was something like html - body - root - ...
html and body was overflow: hidden
, and root was position: fixed, height: 100vh
.
Whith this layout browser tabs on mobile doesnt hide.
For solve this I delete overflow: hidden
from html and body and delete position: fixed
, height: 100vh
from root.
select substring(substring('B10000N0Z', patindex('%[0]%','B10000N0Z'), 20),
patindex('%[^0]%',substring('B10000N0Z', patindex('%[0]%','B10000N0Z'),
20)), 20)
returns N0Z
, that is, will get rid of leading zeroes and anything that comes before them.
You don't need to escape the '
character in a String (wrapped in "
), and you don't have to escape a "
character in a char (wrapped in '
).
You can use toLocaleString(). This is a javascript method.
var event = new Date("01/02/1993");_x000D_
_x000D_
var options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };_x000D_
_x000D_
console.log(event.toLocaleString('en', options));_x000D_
_x000D_
// expected output: "Saturday, January 2, 1993"
_x000D_
Almost all formats supported. Have look on this link for more details.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString
Returns true if comes 'y', '1', 'true', 'on'or whatever you add in similar way
boolean getValue(String value) {
return ("Y".equals(value.toUpperCase())
|| "1".equals(value.toUpperCase())
|| "TRUE".equals(value.toUpperCase())
|| "ON".equals(value.toUpperCase())
);
}
Seems bundler can't use .gem files out of the box. Pointing the :path to a directory containing .gem files doesn't work. Some people suggested to setup a local gem server (geminabox, stickler) for that purpose.
However, what I found to be much simpler is to use a local gem "server" from file system: Just put your .gem files in a local directory, then use "gem generate_index" to make it a Gem repository
mkdir repo
mkdir repo/gems
cp *.gem repo/gems
cd repo
gem generate_index
Finally point bundler to this location by adding the following line to your Gemfile
source "file://path/to/repo"
If you update the gems in the repository, make sure to regenerate the index.
I had my tryst with KSOAP; I chose a rather simpler approach.
Given a WSDL file, create SOAP Request templates for each Request(for e.g.: using SOAP UI) and then substitute the values to be passed in code. POST this data to the service end point using DefaultHttpClient instance and get the response stream. Parse the Response Stream using an XML Pull parser.
I found an excellent utility that is configurable at https://github.com/acch/genfiles.
It fills the target file with random data, so there are no problems with sparse files, and for my purposes (testing compression algorithms) it gives a nice level of white noise.
virtualenv
is a very popular tool that creates isolated Python environments for Python libraries. If you're not familiar with this tool, I highly recommend learning it, as it is a very useful tool, and I'll be making comparisons to it for the rest of this answer.
It works by installing a bunch of files in a directory (eg: env/
), and then modifying the PATH
environment variable to prefix it with a custom bin
directory (eg: env/bin/
). An exact copy of the python
or python3
binary is placed in this directory, but Python is programmed to look for libraries relative to its path first, in the environment directory. It's not part of Python's standard library, but is officially blessed by the PyPA (Python Packaging Authority). Once activated, you can install packages in the virtual environment using pip
.
pyenv
is used to isolate Python versions. For example, you may want to test your code against Python 2.7, 3.6, 3.7 and 3.8, so you'll need a way to switch between them. Once activated, it prefixes the PATH
environment variable with ~/.pyenv/shims
, where there are special files matching the Python commands (python
, pip
). These are not copies of the Python-shipped commands; they are special scripts that decide on the fly which version of Python to run based on the PYENV_VERSION
environment variable, or the .python-version
file, or the ~/.pyenv/version
file. pyenv
also makes the process of downloading and installing multiple Python versions easier, using the command pyenv install
.
pyenv-virtualenv
is a plugin for pyenv
by the same author as pyenv
, to allow you to use pyenv
and virtualenv
at the same time conveniently. However, if you're using Python 3.3 or later, pyenv-virtualenv
will try to run python -m venv
if it is available, instead of virtualenv
. You can use virtualenv
and pyenv
together without pyenv-virtualenv
, if you don't want the convenience features.
virtualenvwrapper
is a set of extensions to virtualenv
(see docs). It gives you commands like mkvirtualenv
, lssitepackages
, and especially workon
for switching between different virtualenv
directories. This tool is especially useful if you want multiple virtualenv
directories.
pyenv-virtualenvwrapper
is a plugin for pyenv
by the same author as pyenv
, to conveniently integrate virtualenvwrapper
into pyenv
.
pipenv
aims to combine Pipfile
, pip
and virtualenv
into one command on the command-line. The virtualenv
directory typically gets placed in ~/.local/share/virtualenvs/XXX
, with XXX
being a hash of the path of the project directory. This is different from virtualenv
, where the directory is typically in the current working directory. pipenv
is meant to be used when developing Python applications (as opposed to libraries). There are alternatives to pipenv
, such as poetry
, which I won't list here since this question is only about the packages that are similarly named.
pyvenv
is a script shipped with Python 3 but deprecated in Python 3.6 as it had problems (not to mention the confusing name). In Python 3.6+, the exact equivalent is python3 -m venv
.
venv
is a package shipped with Python 3, which you can run using python3 -m venv
(although for some reason some distros separate it out into a separate distro package, such as python3-venv
on Ubuntu/Debian). It serves the same purpose as virtualenv
, but only has a subset of its features (see a comparison here). virtualenv
continues to be more popular than venv
, especially since the former supports both Python 2 and 3.
This is my personal recommendation for beginners: start by learning virtualenv
and pip
, tools which work with both Python 2 and 3 and in a variety of situations, and pick up other tools once you start needing them.
There are security flaws to using preg_replace(), if you get the payload from user input [or other untrusted sources]. PHP executes the regular expression with eval(). If the incoming string isn't properly sanitized, your application risks being subjected to code injection.
In my own application, instead of bothering sanitizing the input (and as I only deal with short strings), I instead made a slightly more processor intensive function, though which is secure, since it doesn't eval() anything.
function secureRip(string $str): string { /* Rips all whitespace securely. */
$arr = str_split($str, 1);
$retStr = '';
foreach ($arr as $char) {
$retStr .= trim($char);
}
return $retStr;
}
Now, sometimes you already have less
open, and you can't use cat
on it. For example, you did a | less
, and you can't just reopen a file, as that's actually a stream.
If all you need is to identify end of line, one easy way is to search for the last character on the line: /.$
. The search will highlight the last character, even if it is a blank, making it easy to identify it.
That will only help with the end of line case. If you need other special characters, you can use the cat -vet
solution above with marks and pipe:
ma
mb
'a
cat -vet
and view the result in another less command: |bcat -vet | less
This will open another less
process, which shows the result of running cat -vet
on the text that lies between marks a and b.
If you want the whole thing, instead, do g|$cat -vet | less
, to go to the first line and filter all lines through cat
.
The advantage of this method over less
options is that it does not mess with the output you see on the screen.
One would think that eight years after this question was originally posted, less
would have that feature... But I can't even see a feature request for it on https://github.com/gwsw/less/issues
str.match(pattern)
, if pattern
has the global flag g
, will return all the matches as an array.
For example:
const str = 'All of us except @Emran, @Raju and @Noman was there';_x000D_
console.log(_x000D_
str.match(/@\w*/g)_x000D_
);_x000D_
// Will log ["@Emran", "@Raju", "@Noman"]
_x000D_
used a reference like "///<reference path="web.ts" />
and then in the VS2013 project properties for building "app.ts","Typescript Build"->"Combine javascript output into file:"(checked)->"app.js"
If for some people (like me earlier) the above answers don't work, I think the following answer would work (for Mac users I think) Enter the following commands to do flask run
$ export FLASK_APP = hello.py
$ export FLASK_ENV = development
$ flask run
Alternatively you can do the following (I haven't tried this but one resource online talks about it)
$ export FLASK_APP = hello.py
$ python -m flask run

You wont be able to do this from the client side because of the Same Origin Policy set by the browsers. You wont be able to get much information from the iFrame other than basic properties like its width and height.
Also, google sets in its response header an 'X-Frame-Options' of SAMEORIGIN.
Even if you did an ajax call to google you wont be able to inspect the response because the browser enforcing Same Origin Policy.
So, the only option is to make the request from your server to see if you can display the site in your IFrame.
So, on your server.. your web app would make a request to www.google.com and then inspect the response to see if it has a header argument of X-Frame-Options. If it does exist then you know the IFrame will error.

If I understand your question correctly, here are four methods to do the equivalent of Excel's VLOOKUP
and fill down using R
:
# load sample data from Q
hous <- read.table(header = TRUE,
stringsAsFactors = FALSE,
text="HouseType HouseTypeNo
Semi 1
Single 2
Row 3
Single 2
Apartment 4
Apartment 4
Row 3")
# create a toy large table with a 'HouseType' column
# but no 'HouseTypeNo' column (yet)
largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType), 1000, replace = TRUE)), stringsAsFactors = FALSE)
# create a lookup table to get the numbers to fill
# the large table
lookup <- unique(hous)
HouseType HouseTypeNo
1 Semi 1
2 Single 2
3 Row 3
5 Apartment 4
Here are four methods to fill the HouseTypeNo
in the largetable
using the values in the lookup
table:
First with merge
in base:
# 1. using base
base1 <- (merge(lookup, largetable, by = 'HouseType'))
A second method with named vectors in base:
# 2. using base and a named vector
housenames <- as.numeric(1:length(unique(hous$HouseType)))
names(housenames) <- unique(hous$HouseType)
base2 <- data.frame(HouseType = largetable$HouseType,
HouseTypeNo = (housenames[largetable$HouseType]))
Third, using the plyr
package:
# 3. using the plyr package
library(plyr)
plyr1 <- join(largetable, lookup, by = "HouseType")
Fourth, using the sqldf
package
# 4. using the sqldf package
library(sqldf)
sqldf1 <- sqldf("SELECT largetable.HouseType, lookup.HouseTypeNo
FROM largetable
INNER JOIN lookup
ON largetable.HouseType = lookup.HouseType")
If it's possible that some house types in largetable
do not exist in lookup
then a left join would be used:
sqldf("select * from largetable left join lookup using (HouseType)")
Corresponding changes to the other solutions would be needed too.
Is that what you wanted to do? Let me know which method you like and I'll add commentary.

Found a nice solution in another Stackoverflow post (using only standard libraries + dealing with jpg as well): JohnTESlade answer
And another solution (the quick way) for those who can afford running 'file' command within python, run:
import os
info = os.popen("file foo.jpg").read()
print info
Output:
foo.jpg: JPEG image data...density 28x28, segment length 16, baseline, precision 8, 352x198, frames 3
All you gotta do now is to format the output to capture the dimensions. 352x198 in my case.
Bitcode refers to to the type of code: "LLVM Bitcode" that is sent to iTunes Connect. This allows Apple to use certain calculations to re-optimize apps further (e.g: possibly downsize executable sizes). If Apple needs to alter your executable then they can do this without a new build being uploaded.
This differs from: Slicing which is the process of Apple optimizing your app for a user's device based on the device's resolution and architecture. Slicing does not require Bitcode. (Ex: only including @2x images on a 5s)
App Thinning is the combination of slicing, bitcode, and on-demand resources
Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.
Or if you need it in a loop
foreach ($array as $key => $value)
{
echo $key . ':' . $value . "\n";
}
//Result:
//one:value
//two:value2
Yes, just open the "Source" Tab in the dev-tools and navigate to the script you want to change . Make your adjustments directly in the dev tools window and then hit ctrl+s to save the script - know the new js will be used until you refresh the whole page.
You could use str_replace
to replace the <br />
tags into end of line characters.
str_replace('<br />', PHP_EOL, $textarea);
Alternatively, you could save the data in the database without calling nl2br
first. That way the line breaks would remain. When you display as HTML, call nl2br
. An additional benefit of this approach is that it would require less storage space in your database as a line break is 1 character as opposed to "<br />
" which is 6.
QColorDialog *dialog = new QColorDialog(this);
QColor color= dialog->getColor();
QVariant variant= color;
QString colcode = variant.toString();
ui->label->setStyleSheet("QLabel { background-color :"+colcode+" ; color : blue; }");
getColor()
method returns the selected color.
You can change label color using stylesheet
Your original problem was that you were checking if the list was null, which it would never be because you instantiated it with List<Integer> numbers = new ArrayList<Integer>();
. However, you have updated your code to use the List.isEmpty()
method to properly check if the list is empty.
The problem now is that you are never actually sending an empty list to giveList()
. In your do-while loop, you add any input number to the list, even if it is -1. To prevent -1 being added, change the do-while loop to only add numbers if they are not -1. Then, the list will be empty if the user's first input number is -1.
do {
number = Integer.parseInt(JOptionPane.showInputDialog("Enter a number (-1 to stop)"));
/* Change this line */
if (number != -1) numbers.add(number);
} while (number != -1);
Setting session timeout through the deployment descriptor should work - it sets the default session timeout for the web app. Calling session.setMaxInactiveInterval() sets the timeout for the particular session it is called on, and overrides the default. Be aware of the unit difference, too - the deployment descriptor version uses minutes, and session.setMaxInactiveInterval() uses seconds.
So
<session-config>
<session-timeout>60</session-timeout>
</session-config>
sets the default session timeout to 60 minutes.
And
session.setMaxInactiveInterval(600);
sets the session timeout to 600 seconds - 10 minutes - for the specific session it's called on.
This should work in Tomcat or Glassfish or any other Java web server - it's part of the spec.
You are tying one had behind your back saying that you won't use the LESS files. I built my first Twitter Bootstrap theme using 2.0, and I did everything in CSS -- creating an override.css file. It took days to get things to work correctly.
Now we have 3.0. Let me assure you that it takes less time to learn LESS, which is pretty straight forward if you're comfortable with CSS, than doing all of those crazy CSS overrides. Making changes like the one you want is a piece of cake.
In Bootstrap 3.0, the container class controls the width, and all of the contained styles adjust to fill the container. The container width variables are at the bottom of the variables.less file.
// Container sizes
// --------------------------------------------------
// Small screen / tablet
@container-tablet: ((720px + @grid-gutter-width));
// Medium screen / desktop
@container-desktop: ((940px + @grid-gutter-width));
// Large screen / wide desktop
@container-lg-desktop: ((1020px + @grid-gutter-width));
Some sites either don't have enough content to fill the 1020 display or you want a narrower frame for aesthetic reasons. Because BS uses a 12-column grid I use a multiple like 960.

Because otherwise scanf will think you are passing a pointer to a float which is a smaller size than a double, and it will return an incorrect value.

I had a similar problem. I wanted to find a string in one column and put that value in another column in the same table. The select statement below finds the text inside the parens.
When I created the query in Access I selected all fields. On the SQL view for that query, I replaced the mytable.myfield for the field I wanted to have the value from inside the parens with
SELECT Left(Right(OtherField,Len(OtherField)-InStr((OtherField),"(")),
Len(Right(OtherField,Len(OtherField)-InStr((OtherField),"(")))-1)
I ran a make table query. The make table query has all the fields with the above substitution and ends with INTO NameofNewTable FROM mytable
You'll want to use a number of layout managers to help you achieve the basic results you want.
Check out A Visual Guide to Layout Managers for a comparision.
You could use a GridBagLayout
but that's one of the most complex (and powerful) layout managers available in the JDK.
You could use a series of compound layout managers instead.
I'd place the graphics component and text area on a single JPanel
, using a BorderLayout
, with the graphics component in the CENTER

I'd place the text field and button on a separate JPanel

(because it's the simplest I can think of to achieve the over result you want)
I'd place these two panels onto a third, master, panel, using a BorderLayout

If you are using the Firefox add-on sqlite-manager you can do the following:
Instead of dropping and creating the table again one can just modify it like this.
In the Columns text box, right click on the last column name listed to bring up the context menu and select Edit Column. Note that if the last column in the TABLE definition is the PRIMARY KEY then it will be necessary to first add a new column and then edit the column type of the new column in order to add the FOREIGN KEY definition. Within the Column Type box , append a comma and the
FOREIGN KEY (parent_id) REFERENCES parent(id)
definition after data type. Click on the Change button and then click the Yes button on the Dangerous Operation dialog box.

If you use Packer, just go far the 'shrink variables' option and gzip the resulting code. The base62 option is only for if your server cannot send gzipped files. Packer with 'shrink vars' achieves better compression the YUI, but can introduce bugs if you've skipped a semicolon somewhere.
base62 is basically a poor man's gzip, which is why gzipping base62-ed code gives you bigger files than gzipping shrink-var-ed code.
Use map function
var values = $("input[name^='card']").map(function (idx, ele) {
return $(ele).val();
}).get();
On my machine I tried check it. My result:
Calendar.getInstance().getTime() (*1000000 times) = 402ms new Date().getTime(); (*1000000 times) = 18ms System.currentTimeMillis() (*1000000 times) = 16ms
Don't forget about GC (if you use Calendar.getInstance()
or new Date()
)
In my case, I want the name of the renamed file to be unique, so I add a date-time stamp to the name. This way, the filename of the 'old' log is always unique:
if (File.Exists(clogfile))
{
Int64 fileSizeInBytes = new FileInfo(clogfile).Length;
if (fileSizeInBytes > 5000000)
{
string path = Path.GetFullPath(clogfile);
string filename = Path.GetFileNameWithoutExtension(clogfile);
System.IO.File.Move(clogfile, Path.Combine(path, string.Format("{0}{1}.log", filename, DateTime.Now.ToString("yyyyMMdd_HHmmss"))));
}
}

The checkbox is in a td
, so need to get the parent first:
$("input:checkbox").on("change", function() {
$(this).parent().next().find("label").text("TESTTTT");
});
Alternatively, find a label which has a for
with the same id
(perhaps more performant than reverse traversal) :
$("input:checkbox").on("change", function() {
$("label[for='" + $(this).attr('id') + "']").text("TESTTTT");
});
Or, to be more succinct just this.id
:
$("input:checkbox").on("change", function() {
$("label[for='" + this.id + "']").text("TESTTTT");
});
I haven't seen Log Expert anywhere among answers here.
It's customizable and is quite good for going around log files. So far it's the best Windows graphical log viewer for me.
Unfortunately, this software is no longer available. You can read about it on archive.org.
Do this by either going to my computer and then right clicking the background for the context menu > "properties". On the left side open "advanced system settings" or just search for "env..." in start menu ([Win]+[s] keys).
Then click on environment variables
If you struggle with this step read this explanation.
D:\path\to\anaconda3
D:\path\to\anaconda3\Scripts
D:\path\to\anaconda3\Library\bin
D:\path\to\anaconda3
should be the folder where you have installed anaconda
Click [OK] on all opened windows.
If you did everything correctly, you can test a conda
command by opening a new powershell window.
conda --version
This should output something like: conda 4.8.2
Providing some other solution; we're also using react-native-image-picker
; and the server side is using koa-multer
; this set-up is working good:
ui
ImagePicker.showImagePicker(options, (response) => {
if (response.didCancel) {}
else if (response.error) {}
else if (response.customButton) {}
else {
this.props.addPhoto({ // leads to handleAddPhoto()
fileName: response.fileName,
path: response.path,
type: response.type,
uri: response.uri,
width: response.width,
height: response.height,
});
}
});
handleAddPhoto = (photo) => { // photo is the above object
uploadImage({ // these 3 properties are required
uri: photo.uri,
type: photo.type,
name: photo.fileName,
}).then((data) => {
// ...
});
}
client
export function uploadImage(file) { // so uri, type, name are required properties
const formData = new FormData();
formData.append('image', file);
return fetch(`${imagePathPrefix}/upload`, { // give something like https://xx.yy.zz/upload/whatever
method: 'POST',
body: formData,
}
).then(
response => response.json()
).then(data => ({
uri: data.uri,
filename: data.filename,
})
).catch(
error => console.log('uploadImage error:', error)
);
}
server
import multer from 'koa-multer';
import RouterBase from '../core/router-base';
const upload = multer({ dest: 'runtime/upload/' });
export default class FileUploadRouter extends RouterBase {
setupRoutes({ router }) {
router.post('/upload', upload.single('image'), async (ctx, next) => {
const file = ctx.req.file;
if (file != null) {
ctx.body = {
uri: file.filename,
filename: file.originalname,
};
} else {
ctx.body = {
uri: '',

}
});

}
In your xampppath\apache\conf\extra open file httpd-xampp.conf and find the below tag:
# Close XAMPP sites here
<LocationMatch "^/(?i:(?:xampp|licenses|phpmyadmin|webalizer|server-status|server-info))">
Order deny,allow
Deny from all
Allow from ::1 127.0.0.0/8
ErrorDocument 403 /error/HTTP_XAMPP_FORBIDDEN.html.var
</LocationMatch>
and add
"Allow from all"
after Allow from ::1 127.0.0.0/8 {line}
Restart xampp, and you are done.
In later versions of Xampp
...you can simply remove this part
#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">

from the same file and it should work over the local network.
git
isn't a centralized scm like svn
so you have two options:
It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.
An example with fetching into a temporary directory:
git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline
Alternatively:
git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master
Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.
An example with GitHub:
GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3
An example with GitLab:
GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3
Both are really fast but have different interfaces (like every platform).
Disclaimer: Rust and Inkscape were chosen because of their size and safety to stay, no advertisement
The best way to access files from resource folder inside a jar is it to use the InputStream via getResourceAsStream
. If you still need a the resource as a file instance you can copy the resource as a stream into a temporary file (the temp file will be deleted when the JVM exits):
public static File getResourceAsFile(String resourcePath) {
try {
InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
if (in == null) {
return null;
}
File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
tempFile.deleteOnExit();
try (FileOutputStream out = new FileOutputStream(tempFile)) {
//copy stream
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = in.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
}
}
return tempFile;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
If you have deadlocks occurring in a combination of locks, threads and forks in the logging
module, that is reported in bug report 6721 (see also related SO question).
There is a small fixup solution posted here.
However, that will just fix any potential deadlocks in logging
. That will not fix that things are maybe garbled up. See the other answers presented here.
if (combo1.SelectedIndex > -1)
{
// do something
}
if any item is selected selected index will be greater than -1
XOR
is short for exclusive or. It is a logical, binary operator that requires that one of the two operands be true but not both.
So these statements are true:
TRUE XOR FALSE
FALSE XOR TRUE
And these statements are false:
FALSE XOR FALSE
TRUE XOR TRUE
There really isn't such a thing as an"exclusive and" (or XAND
) since in theory it would have the same exact requirements as XOR
. There also isn't an XNOT
since NOT
is a unary operator that negates its single operand (basically it just flips a boolean value to its opposite) and as such it cannot support any notion of exclusivity.
I'm not 100% sure what your NonIntersect method is supposed to do (regarding set theory) - is it
B \ A (everything from B that does not occur in A)?
If yes, then you should be able to use the Except operation (B.Except(A)).
In case you couldn't find "Import code" button on github, you can:
url
. It will look like: Public
or Private
repoBegin Import
UPDATE: Recently, Github announced the ability to "Import repositories with large files"

the worked proposition for me is __call__

start = 10
end = 100
for cmb in range(2, len(str(self.how_much)) + 1):

start *= 10
end *= 10
def __call__(self, number, *args, **kwargs):

for subset in itertools.product(*multi_work_list):
if is_upper_then <= nbr < is_under_then:
self.generated_list.append(''.join(subset))
if self.how_much == nbr:
break
nbr += 1
and to run it:
if __name__ == '__main__':
sm = SmallNumbers(56)
print(sm.generated_list)
print(sm.generated_list[34], sm.generated_list[27], sm.generated_list[10])

ArrayList
and Vector
both implements List interface and maintains insertion order.But there are many differences between ArrayList
and Vector
classes...
ArrayList
is not synchronized.ArrayList
increments 50% of current array size if number of element exceeds from its capacity.ArrayList
is not a legacy class, it is introduced in JDK 1.2.ArrayList
is fast because it is non-synchronized.ArrayList
uses Iterator interface to traverse the elements.Vector -
Vector
is synchronized.Vector
increments 100% means doubles the array size if total number of element exceeds than its capacity.Vector
is a legacy class.
Vector
is slow because it is synchronized i.e. in multithreading environment, it will hold the other threads in runnable or non-runnable state until current thread releases the lock of object.
Vector
uses Enumeration interface to traverse the elements. But it can use Iterator also.
See Also : https://www.javatpoint.com/difference-between-arraylist-and-vector
.each()
should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map
.
var newArray = $(array).map(function(i) {
return $('#event' + i, response).html();
});
Edit: I removed the adding of the prepended 0 since it is suggested to not use that.
If you must have it use
var newArray = $(array).map(function(i) {
var number = '' + i;
if (number.length == 1) {
number = '0' + number;
}
return $('#event' + number, response).html();
});
It’s just HTML with Server Side Includes.
My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v
if you just want that...
I find htop
a useful tool.
sudo apt-get install htop
and then
free -m
will give the information you need.
string connectionString= ServerName + DatabaseName + SecurityType;
using (SqlConnection connection = new SqlConnection(connectionString))

connection.Open();
bulkCopy.DestinationTableName = "TableName";
try {
bulkCopy.WriteToServer(dataTableName);
} catch (Exception e) {
Console.Write(e.Message);
}
}
Please note that the structure of the database table and the table name should be the same or it will throw an exception.
Those who use WPF
for (int i = 0; i < dataGridName.Items.Count; i++)
{
string cellValue= ((DataRowView)dataGridName.Items[i]).Row["columnName"].ToString();
if (cellValue.Equals("Search_string")) // check the search_string is present in the row of ColumnName
{
object item = dataGridName.Items[i];
dataGridName.SelectedItem = item; // selecting the row of dataGridName
dataGridName.ScrollIntoView(item);
break;
}
}
if you want to get the selected row items after this, the follwing code snippet is helpful
DataRowView drv = dataGridName.SelectedItem as DataRowView;
DataRow dr = drv.Row;
string item1= Convert.ToString(dr.ItemArray[0]);// get the first column value from selected row
string item2= Convert.ToString(dr.ItemArray[1]);// get the second column value from selected row
After five years, I can see this is still a very relevant subject. Somewhat mirroring leucos's answer which I find the best in my case, using ansible tools only (without any centralised authentication, tokens or whatever). This assumes you have the same username and the same public key on all servers. If you don't, of course you'd need to be more specific and add the corresponding variables next to the hosts:
[all:vars]
ansible_ssh_user=ansible
ansible_ssh_private_key_file=home/user/.ssh/mykey
[group]
192.168.0.50 ansible_sudo_pass='{{ myserver_sudo }}'
ansible-vault create mypasswd.yml
ansible-vault edit mypasswd.yml
Add:
myserver_sudo: mysecretpassword
Then:
ansible-playbook -i inv.ini my_role.yml --ask-vault --extra-vars '@passwd.yml'
At least this way you don't have to write more the variables which point to the passwords.
Kill the braces.
var defaults = {
backgroundcolor: '#000',
color: '#fff',
weekdays: ['sun','mon','tue','wed','thu','fri','sat']
};
This is very confusing, and if you are using IDE like pycharm, it's little more confusing. What worked for me: 1. Make pycharm project settings (if you are running python from a VE or from python directory) 2. There is no wrong the way you defined. sometime it works with from folder1.file1 import class
if it does not work, use import folder1.file1 3. Your environment variable should be correctly mentioned in system or provide it in your command line argument.
Under Windows7 Pro, I found that Arun's solution worked for me: I could get this to work even with "no user logged on", I did choose use highest priveledges.
From past experience, you must have an account with a password (blank passwords are no good), and if the program doesn't prompt you for the password when you finish the wizard, go back in and edit something till it does!
This is the method in case its not clear which worked
Action: start a program
Program/script : cmd
(doesn't need the .exe bit!)
Add arguments:
/c start "" "E:\Django-1.4.1\setup.bat"
List comprehension will lead you to a solution.
But the right way to copy a object in python is using python module copy - Shallow and deep copy operations.
l=[1,2,3,0,0,1]
for i in range(0,len(l)):
if l[i]==0:
l.pop(i)
If instead of this,
import copy
l=[1,2,3,0,0,1]
duplicate_l = copy.copy(l)
for i in range(0,len(l)):
if l[i]==0:
m.remove(i)
l = m
Then, your own code would have worked. But for optimization, list comprehension is a good solution.
System read-only variable %CD%
keeps the path of the caller of the batch, not the batch file location.
You can get the name of the batch script itself as typed by the user with %0
(e.g. scripts\mybatch.bat
). Parameter extensions can be applied to this so %~dp0
will return the Drive and Path to the batch script (e.g. W:\scripts\
) and %~f0
will return the full pathname (e.g. W:\scripts\mybatch.cmd
).
You can refer to other files in the same folder as the batch script by using this syntax:
CALL %0\..\SecondBatch.cmd
This can even be used in a subroutine, Echo %0
will give the call label but, echo "%~nx0"
will give you the filename of the batch script.
When the %0
variable is expanded, the result is enclosed in quotation marks.
I resolved by adding - %AppData%\npm\node_modules@angular\cli\bin\ path to my environment variables path
If the charset of the tables is the same as it's content try to use mysql_set_charset('UTF8', $link_identifier)
. Note that MySQL uses UTF8
to specify the UTF-8 encoding instead of UTF-8
which is more common.
Check my other answer on a similar question too.
But what if the container is not the viewport (body)?
The real answer is in the transform property allows you to visually manipulate an element by skewing, rotating, translating, or scaling:
This is not possible from HTML on. The closest what you can get is the accept-charset
attribute of the <form>
. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type
header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.
To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding
attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).
Update:
Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type
header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.
(This is already answered in comments, but since it lacks an actual answer, I'm writing this.)
This problem arises in newer versions of Visual C++ (the older versions usually just silently linked the program and it would crash and burn at run time.) It means that some of the libraries you are linking with your program (or even some of the source files inside your program itself) are using different versions of the CRT (the C RunTime library.)
To correct this error, you need to go into your Project Properties
(and/or those of the libraries you are using,) then into C/C++
, then Code Generation
, and check the value of Runtime Library
; this should be exactly the same for all the files and libraries you are linking together. (The rules are a little more relaxed for linking with DLLs, but I'm not going to go into the "why" and into more details here.)
There are currently four options for this setting:
Your particular problem seems to stem from you linking a library built with "Multithreaded Debug" (i.e. static multithreaded debug CRT) against a program that is being built using the "Multithreaded Debug DLL" setting (i.e. dynamic multithreaded debug CRT.) You should change this setting either in the library, or in your program. For now, I suggest changing this in your program.
Note that since Visual Studio projects use different sets of project settings for debug and release builds (and 32/64-bit builds) you should make sure the settings match in all of these project configurations.
For (some) more information, you can see these (linked from a comment above):
UPDATE: (This is in response to a comment that asks for the reason that this much care must be taken.)
If two pieces of code that we are linking together are themselves linking against and using the standard library, then the standard library must be the same for both of them, unless great care is taken about how our two code pieces interact and pass around data. Generally, I would say that for almost all situations just use the exact same version of the standard library runtime (regarding debug/release, threads, and obviously the version of Visual C++, among other things like iterator debugging, etc.)
The most important part of the problem is this: having the same idea about the size of objects on either side of a function call.
Consider for example that the above two pieces of code are called A
and B
. A is compiled against one version of the standard library, and B against another. In A's view, some random object that a standard function returns to it (e.g. a block of memory or an iterator or a FILE
object or whatever) has some specific size and layout (remember that structure layout is determined and fixed at compile time in C/C++.) For any of several reasons, B's idea of the size/layout of the same objects is different (it can be because of additional debug information, natural evolution of data structures over time, etc.)
Now, if A calls the standard library and gets an object back, then passes that object to B, and B touches that object in any way, chances are that B will mess that object up (e.g. write the wrong field, or past the end of it, etc.)
The above isn't the only kind of problems that can happen. Internal global or static objects in the standard library can cause problems too. And there are more obscure classes of problems as well.
All this gets weirder in some aspects when using DLLs (dynamic runtime library) instead of libs (static runtime library.)
This situation can apply to any library used by two pieces of code that work together, but the standard library gets used by most (if not almost all) programs, and that increases the chances of clash.
What I've described is obviously a watered down and simplified version of the actual mess that awaits you if you mix library versions. I hope that it gives you an idea of why you shouldn't do it!
Do you mean this?
var listOfList = new List<List<int>>() {
new List<int>() { 1, 2 },
new List<int>() { 3, 4 },
new List<int>() { 5, 6 }
};
var list = new List<int> { 9, 9, 9 };
var result = list.Concat(listOfList.SelectMany(x => x));
foreach (var x in result) Console.WriteLine(x);
Results in: 9 9 9 1 2 3 4 5 6

Add your JDK's /bin folder to the PATH
environmental variable. You can do this under System settings > Environmental variables, or via CLI:
set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
Close and reopen your CLI window
You can determine window
scroll bar with document
as below using jquery + javascript:
var scrollbarWidth = ($(document).width() - window.innerWidth);
console.info("Window Scroll Bar Width=" + scrollbarWidth );
I am using below code for today and database date.

In C# 7 it's possible to use a when clause in a case statement.
int age = 12;
switch (age)
{
case int i when i >=1 && i <= 8:
System.Console.WriteLine("You are only " + age + " years old. You must be kidding right. Please fill in your *real* age.");
break;
case int i when i >=9 && i <= 15:
System.Console.WriteLine("You are only " + age + " years old. That's too young!");
break;
case int i when i >=16 && i <= 100:
System.Console.WriteLine("You are " + age + " years old. Perfect.");
break;
default:
System.Console.WriteLine("You an old person.");
break;
}
There are many possibilities to solve this task.
The easiest solution is running the batch file with full path.
"F:\- Big Packets -\kitterengine\Common\Template.bat"
Once end of batch file Template.bat
is reached, there is no return to previous script in case of the command line above is within a *.bat or *.cmd file.
The current directory for the batch file Template.bat
is the current directory of the current process. In case of Template.bat
requires that the directory of this batch file is the current directory, the batch file Template.bat
should contain after @echo off
as second line the following command line:
cd /D "%~dp0"
Run in a command prompt window cd /?
for getting displayed the help of this command explaining parameter /D
... change to specified directory also on a different drive.
Run in a command prompt window call /?
for getting displayed the help of this command used also in 2., 4. and 5. solution and explaining also %~dp0
... drive and path of argument 0 which is the name of the batch file.
Another solution is calling the batch file with full path.
call "F:\- Big Packets -\kitterengine\Common\Template.bat"
The difference to first solution is that after end of batch file Template.bat
is reached the batch processing continues in batch script containing this command line.
For the current directory read above.
There are 3 operators for running multiple commands on one command line: &
, &&
and ||
.
For details see answer on Single line with multiple commands using Windows batch file
I suggest for this task the &&
operator.
cd /D "F:\- Big Packets -\kitterengine\Common" && Template.bat
As on first solution there is no return to current script if this is a *.bat or *.cmd file and changing the directory and continuation of batch processing on Template.bat
is successful.
This command line changes the directory and on success calls the batch file.
cd /D "F:\- Big Packets -\kitterengine\Common" && call Template.bat
The difference to third solution is the return to current batch script on exiting processing of Template.bat
.
The four solutions above change the current directory and it is unknown what Template.bat
does regarding
In case of it is important to keep the environment of current *.bat or *.cmd script unmodified by whatever Template.bat
changes on environment for itself, it is advisable to use setlocal
and endlocal
.
Run in a command prompt window setlocal /?
and endlocal /?
for getting displayed the help of these two commands. And read answer on change directory command cd ..not working in batch file after npm install explaining more detailed what these two commands do.
setlocal & cd /D "F:\- Big Packets -\kitterengine\Common" & call Template.bat & endlocal
Now there is only &
instead of &&
used as it is important here that after setlocal
is executed the command endlocal
is finally also executed.
ONE MORE NOTE
If batch file Template.bat
contains the command exit
without parameter /B
and this command is really executed, the command process is always exited independent on calling hierarchy. So make sure Template.bat
contains exit /B
or goto :EOF
instead of just exit
if there is exit
used at all in this batch file.
As the others have said already, your first line should be
#!/usr/bin/env ruby
And you also have to make it executable: (in the shell)
chmod +x test.rb
Then follows the ruby code. If you open a file
File.open("file", "r") do |io|
# do something with io
end
the file is opened in the current directory you'd get with pwd
in the shell.
The path to your script is also simple to get. With $0
you get the first argument of the shell, which is the relative path to your script. The absolute path can be determined like that:
#!/usr/bin/env ruby
require 'pathname'
p Pathname.new($0).realpath()
For file system operations I almost always use Pathname. This is a wrapper for many of the other file system related classes. Also useful: Dir, File...
Use the text method [text()
] to get text in the div element,
by identifing the element by class or id.
You can run the ant task echoproperties
and look for "java.version" or ant -v
and look for "Java version", e.g. on my machine
ant echoproperties | grep java.version
shows
[echoproperties] java.version=11.0.9.1
and
ant -v | grep -i "java version"
shows
Detected Java version: 11 in: /opt/java/zulu11.43.55-ca-jdk11.0.9.1-linux_x64
If you don't care about supporting old browsers, you can use :not()
to exclude that element:
.parent:hover span:not(:hover) {
border: 10px solid red;
}
Demo: http://jsfiddle.net/vz9A9/1/
If you do want to support them, the I guess you'll have to either use JavaScript or override the CSS properties again:
.parent span:hover {
border: 10px solid green;
}
We have solved the same error by following the below steps.
linux command for this type of error occurred then, first of all, check your php.ini file
If your php.ini file exists then in configuration file simply uncomment the extension:
;extension=php_pdo_mysql.dll
Else follow below steps
step1:php -v
step2: Install php mysql extension
php 7.0 sudo apt-get install php7.0-mysql
php 7.1 sudo apt-get install php7.1-mysql
php 7.2 sudo apt-get install php7.2-mysql
php 7.3 sudo apt-get install php7.3-mysql
step3: service apache2 restart
step4: php artisan migrate
I couldn't find an off-the-shelf module that added this function, so I wrote one:
In Access, go to the Database Tools ribbon, in the Macro area click into Visual Basic. In the top left Project area, right click the name of your file and select Insert -> Module. In the module paste this:
Public Function Substring_Index(strWord As String, strDelim As String, intCount As Integer) As String
Substring_Index = delims
start = 0
test = ""
For i = 1 To intCount
oldstart = start + 1
start = InStr(oldstart, strWord, strDelim)
Substring_Index = Mid(strWord, oldstart, start - oldstart)
Next i
End Function
Save the module as module1 (the default). You can now use statements like:
SELECT Substring_Index([fieldname],",",2) FROM table
There is actually a native solution to this, using the four-values to background-position
.CssClass {background-position: right 10px top 20px;}
This means 10px from right and 20px from top. you can also use three values the fourth value will be count as 0.
I've written a little tool called psql2csv
that encapsulates the COPY query TO STDOUT
pattern, resulting in proper CSV. It's interface is similar to psql
.
psql2csv [OPTIONS] < QUERY
psql2csv [OPTIONS] QUERY
The query is assumed to be the contents of STDIN, if present, or the last argument. All other arguments are forwarded to psql except for these:
-h, --help show help, then exit
--encoding=ENCODING use a different encoding than UTF8 (Excel likes LATIN1)
--no-header do not output a header
File 1
class ClassA {
public $name = 'A';
public function getName(){
return $this->name;
}
}
File 2
include("file1.php");
class ClassB {
public $name = 'B';
public function getName(){
return $this->name;
}
public function callA(){
$a = new ClassA();
return $a->getName();
}
public static function callAStatic(){
$a = new ClassA();
return $a->getName();
}
}
$b = new ClassB();
echo $b->callA();
echo $b->getName();
echo ClassB::callAStatic();
To read characters try
scan("/PathTo/file.csv", "")
If you're reading numeric values, then just use
scan("/PathTo/file.csv")
scan
by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).
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.
DATEADD

By default, html buttons submit a form.
This is due to the fact that even buttons located outside of a form act as submitters (see the W3Schools website: http://www.w3schools.com/tags/att_button_form.asp)
In other words, the button type is "submit" by default
<button type="submit">Button Text</button>
Therefore an easy way to get around this is to use the button type.
<button type="button">Button Text</button>
Other options include returning false at the end of the onclick or any other handler for when the button is clicked, or to using an < input> tag instead
To find out more, check out the Mozilla Developer Network's information on buttons: https://developer.mozilla.org/en/docs/Web/HTML/Element/button
Nobody mentioned the ability to use them in switch
statements; I'll throw that in as well.
This allows arbitrarily complex enums to be used in a clean way without using instanceof
, potentially confusing if
sequences, or non-string/int switching values. The canonical example is a state machine.
Thanks guys for help, here is the code I tried which is working for me

instructions.lineBreakMode = NSLineBreakByWordWrapping;
[instructions setTextColor:[UIColor grayColor]];
CGSize expectedLabelSize = [text sizeWithFont:instructions.font

CGRect newFrame = instructions.frame;
newFrame.size.height = expectedLabelSize.height;
instructions.frame = newFrame;
instructions.numberOfLines = 0;
[instructions sizeToFit];
[self addSubview:instructions];

lockless Copy and Write approach works great if you're not dealing with too many items. Here's a class I wrote:
public class CopyAndWriteList<T>
{
public static List<T> Clear(List<T> list)
{
var a = new List<T>(list);
a.Clear();
return a;
}
public static List<T> Add(List<T> list, T item)
{
var a = new List<T>(list);
a.Add(item);
return a;
}
public static List<T> RemoveAt(List<T> list, int index)
{
var a = new List<T>(list);
a.RemoveAt(index);
return a;
}
public static List<T> Remove(List<T> list, T item)
{
var a = new List<T>(list);
a.Remove(item);
return a;
}
}
example usage: orders_BUY = CopyAndWriteList.Clear(orders_BUY);
This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.
change it to:
$(function () {
var specialElementHandlers = {
'#editor': function (element,renderer) {
return true;
}
};
$('#cmd').click(function () {
var doc = new jsPDF();
doc.fromHTML(
$('#target').html(), 15, 15,
{ 'width': 170, 'elementHandlers': specialElementHandlers },
function(){ doc.save('sample-file.pdf'); }
);
});
});
and it will work.

In my case I am using Akcess USB Type C Data Sync Cable For Nexus 5x, 5P - White As Nexus 5x do not supply type C to usb cable I purchased it from some vendor.
Having the same issue. What I am doing stupidly is:- I am connecting the cable in wrong way. After I reconnect it from upside down its working for me.
I might think that some of the Cables do not support debuggable. But its in my case.
This(Image) is my case the Type C should be as USB side symbol. A stupid solution, but work for me
This is because interfaces do not allow to define the method body in it.but we should have to define the constructor in the same class as interfaces have by default abstract modifier for all the methods to define. That's why we can not define constructor in the interfaces.
<ul>
<li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 1" required><label>Box 1</label></li>
<li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 2" required><label>Box 2</label></li>
<li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 3" required><label>Box 3</label></li>
<li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 4" required><label>Box 4</label></li>
</ul>
<script type="text/javascript">
$(document).ready(function(){
var checkboxes = $('.checkboxes');
checkboxes.change(function(){
if($('.checkboxes:checked').length>0) {
checkboxes.removeAttr('required');
} else {
checkboxes.attr('required', 'required');
}
});
});

Replace whatever is in the address bar with this:
javascript:document.getElementById('serverTime').innerHTML='[text here]';
I struggled to solve a similar problem around data table classes instead of messages. The root issue mentioned above of casting a non-generic version of the class to a derived generic version was the same.
In order to allow injection into a portable class library which did not support database libraries, I introduced a set of interface classes, with the intent that I could pass a type and get a matching generic. It ended up needing to implement a generic method.
// Interface for injection
public interface IDatabase
{
// Original, non-functional signature:
IDatatable<object> GetDataTable(Type dataType);
// Functional method using a generic method:
IDatatable<T> GetDataTable<T>();
}
And this the whole implementation using the generic method above.
The generic class that will be cast from a dictionary.
// Non-generic base class allows listing tables together
abstract class Datatable
{
Datatable(Type storedClass)
{
StoredClass = storedClass;
}
Type StoredClass { get; private set; }
}
// Generic inheriting class
abstract class Datatable<T>: Datatable, IDatatable<T>
{
protected Datatable()
:base(typeof(T))
{
}
}
This is the class that stores the generic class and casts it to satisfy the generic method in the interface
class Database
{
// Dictionary storing the classes using the non-generic base class
private Dictionary<Type, Datatable> _tableDictionary;
protected Database(List<Datatable> tables)
{
_tableDictionary = new Dictionary<Type, Datatable>();
foreach (var table in tables)
{
_tableDictionary.Add(table.StoredClass, table);
}
}
// Interface implementation, casts the generic
public IDatatable<T> GetDataTable<T>()
{
Datatable table = null;
_tableDictionary.TryGetValue(typeof(T), out table);
return table as IDatatable<T>;
}
}
And finally the calling of the interface method.
IDatatable<CustomerAccount> table = _database.GetDataTable<CustomerAccount>();
Uncaught InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number
Means you are not passing numbers into the google.maps.LatLng constructor. Per your comment:
/*Information from chromium debugger
trader: Object
geo: Object
lat: "49.014821"
lon: "10.985072"
*/
trader.geo.lat and trader.geo.lon are strings, not numbers. Use parseFloat to convert them to numbers:
var myLatlng = new google.maps.LatLng(parseFloat(trader.geo.lat),parseFloat(trader.geo.lon));
You can modify the id
without having to use getElementById
Example:
<div id = 'One' onclick = "One.id = 'Two'; return false;">One</div>

It can also mean that the server is completely inaccessible - I was getting this when trying to hit a server that was offline
My client was configured to connect to localhost:3000, but no server was running on that port.
This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.

AuthType Basic
AuthName <AUTH_NAME>
Require valid-user
AuthUserFile <FILE_PATH>
</LimitExcept>
In the specific case of sed
, the -i
option that others have already mentioned is far and away the simplest and sanest one.
In the more general case, sponge
, from the moreutils
collection, does exactly what you want: it lets you replace a file with the result of processing it, in a way specifically designed to keep the processing step from tripping over itself by overwriting the very file it's working on. To quote the sponge
man page:
sponge reads standard input and writes it out to the specified file. Unlike a shell redirect, sponge soaks up all its input before writing the output file. This allows constructing pipelines that read from and write to the same file.
Use this:
\d{10}
I hope it helps.
This is not a matter of accuracy, nor is it a matter of precision. It is a matter of meeting the expectations of humans who use base 10 for calculations instead of base 2. For example, using doubles for financial calculations does not produce answers that are "wrong" in a mathematical sense, but it can produce answers that are not what is expected in a financial sense.
Even if you round off your results at the last minute before output, you can still occasionally get a result using doubles that does not match expectations.
Using a calculator, or calculating results by hand, 1.40 * 165 = 231 exactly. However, internally using doubles, on my compiler / operating system environment, it is stored as a binary number close to 230.99999... so if you truncate the number, you get 230 instead of 231. You may reason that rounding instead of truncating would have given the desired result of 231. That is true, but rounding always involves truncation. Whatever rounding technique you use, there are still boundary conditions like this one that will round down when you expect it to round up. They are rare enough that they often will not be found through casual testing or observation. You may have to write some code to search for examples that illustrate outcomes that do not behave as expected.
Assume you want to round something to the nearest penny. So you take your final result, multiply by 100, add 0.5, truncate, then divide the result by 100 to get back to pennies. If the internal number you stored was 3.46499999.... instead of 3.465, you are going to get 3.46 instead 3.47 when you round the number to the nearest penny. But your base 10 calculations may have indicated that the answer should be 3.465 exactly, which clearly should round up to 3.47, not down to 3.46. These kinds of things happen occasionally in real life when you use doubles for financial calculations. It is rare, so it often goes unnoticed as an issue, but it happens.
If you use base 10 for your internal calculations instead of doubles, the answers are always exactly what is expected by humans, assuming no other bugs in your code.
You may also want to try two backslashes (\\")
to escape the escape character.
RequireJS can be configured to append a value to each of the script urls for cache busting.
From the RequireJS documentation (http://requirejs.org/docs/api.html#config):
urlArgs: Extra query string arguments appended to URLs that RequireJS uses to fetch resources. Most useful to cache bust when the browser or server is not configured correctly.
Example, appending "v2" to all scripts:
require.config({
urlArgs: "bust=v2"
});
For development purposes, you can force RequireJS to bypass the cache by appending a timestamp:
require.config({
urlArgs: "bust=" + (new Date()).getTime()
});
How about creating an <a>
with _blank
as target
attribute value and the url
as href
, with style display:hidden with a a children element? Then add to the DOM and then trigger the click event on a children element.
That doesn't work. The browser prevents the default behaviour. It could be triggered programmatically, but it doesn't follow the default behaviour.
Check and see for yourself: http://jsfiddle.net/4S4ET/
You can use String.split(String regex):
String input = "aabbab";
String[] parts = input.split("(?!^)");
I ended up writing a script (I'm trying to teach myself the finer points of bash scripting, so that's why you don't see something like Perl here). It's not exactly a simple affair, but it does most of what I need. It uses Kyle's suggestion for looking up individual users' crontabs, but also deals with /etc/crontab
(including the scripts launched by run-parts
in /etc/cron.hourly
, /etc/cron.daily
, etc.) and the jobs in the /etc/cron.d
directory. It takes all of those and merges them into a display something like the following:
mi h d m w user command
09,39 * * * * root [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -print0 | xargs -r -0 rm
47 */8 * * * root rsync -axE --delete --ignore-errors / /mirror/ >/dev/null
17 1 * * * root /etc/cron.daily/apt
17 1 * * * root /etc/cron.daily/aptitude
17 1 * * * root /etc/cron.daily/find
17 1 * * * root /etc/cron.daily/logrotate
17 1 * * * root /etc/cron.daily/man-db
17 1 * * * root /etc/cron.daily/ntp
17 1 * * * root /etc/cron.daily/standard
17 1 * * * root /etc/cron.daily/sysklogd
27 2 * * 7 root /etc/cron.weekly/man-db
27 2 * * 7 root /etc/cron.weekly/sysklogd
13 3 * * * archiver /usr/local/bin/offsite-backup 2>&1
32 3 1 * * root /etc/cron.monthly/standard
36 4 * * * yukon /home/yukon/bin/do-daily-stuff
5 5 * * * archiver /usr/local/bin/update-logs >/dev/null
Note that it shows the user, and more-or-less sorts by hour and minute so that I can see the daily schedule.
So far, I've tested it on Ubuntu, Debian, and Red Hat AS.

Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.
Simple code example for observing display:none switching:
// Start observing visbility of element. On change, the
// the callback is called with Boolean visibility as
// argument:
function respondToVisibility(element, callback) {
var options = {
root: document.documentElement,
};
var observer = new IntersectionObserver((entries, observer) => {
entries.forEach(entry => {
callback(entry.intersectionRatio > 0);
});
}, options);
observer.observe(element);
}

To complete André's answer, an ant solution could be like the one described in Emacs, JDEE, Ant, and the Eclipse Java Compiler, as in:
<javac
srcdir="${src}"
destdir="${build.dir}/classes">
<compilerarg
compiler="org.eclipse.jdt.core.JDTCompilerAdapter"
line="-warn:+unused -Xemacs"/>
<classpath refid="compile.classpath" />
</javac>
The compilerarg element also allows you to pass in additional command line args to the eclipse compiler.
You can find a full ant script example here which would be invoked in a command line with:
java -cp C:/eclipse-SDK-3.4-win32/eclipse/plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar org.eclipse.core.launcher.Main -data "C:\Documents and Settings\Administrator\workspace" -application org.eclipse.ant.core.antRunner -buildfile build.xml -verbose
BUT all that involves ant, which is not what Keith is after.
For a batch compilation, please refer to Compiling Java code, especially the section "Using the batch compiler"
The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into plugins/org.eclipse.jdt.core_3.4.0..jar. Since 3.2, it is also available as a separate download. The name of the file is ecj.jar.
Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). In order to use the annotations processing support, a 1.6 VM is required.
Running the batch compiler From the command line would give
java -jar org.eclipse.jdt.core_3.4.0<qualifier>.jar -classpath rt.jar A.java
or:
java -jar ecj.jar -classpath rt.jar A.java
All java compilation options are detailed in that section as well.
The difference with the Visual Studio command line compilation feature is that Eclipse does not seem to directly read its .project and .classpath in a command-line argument. You have to report all information contained in the .project and .classpath in various command-line options in order to achieve the very same compilation result.
So, then short answer is: "yes, Eclipse kind of does." ;)
Have you tried using the value in MB ?
php_value memory_limit 2048M
Also try editing this value in php.ini
not Apache.
Use limitTo filter to display a limited number of results in ng-repeat.
<ul class="phones">
<li ng-repeat="phone in phones | limitTo:5">
{{phone.name}}
<p>{{phone.snippet}}</p>
</li>
</ul>
Deleting file .condarc (eg./root/.condarc) in the user's home directory before installation, resolved the issue.
