A simpler way is
ggplot(data=df, aes(x=xvar, y=yvar)) +
geom_point()
ggsave(path = path, width = width, height = height, device='tiff', dpi=700)
Exception may also help:
try {

catch (Exception e) {
//in that case, you may affect "" to myString
myString="";
}

I had a similar requirement to dump the contents of json file for logging, something quick and easy:
print(json.dumps(json.load(open(os.path.join('<myPath>', '<myjson>'), "r")), indent = 4 ))
if you use it often then put it in a function:
def pp_json_file(path, file):
print(json.dumps(json.load(open(os.path.join(path, file), "r")), indent = 4))
from the FAQ
elem = $("#elemid");
if (elem.is (".class")) {
// whatever
}
or:
elem = $("#elemid");
if (elem.hasClass ("class")) {
// whatever
}
If I understood your question, you want to merge branchB
into branchA
. To do so, first checkout branchA
like below,
git checkout branchA
Then execute the below command to merge branchB
into branchA
:
git merge branchB
A different approach, because in my case I needed to also check whether it contained certain words (like 'test' in this example), not characters alone:
input_string = 'abc test'
input_string_test = input_string
allowed_list = ['a', 'b', 'c', 'test', ' ']
for allowed_list_item in allowed_list:
input_string_test = input_string_test.replace(allowed_list_item, '')
if not input_string_test:
# test passed
So, the allowed strings (char or word) are cut from the input string. If the input string only contained strings that were allowed, it should leave an empty string and therefore should pass if not input_string
.
Java conveniently has the instanceof
operator (JLS 15.20.2) to test if a given object is of a given type.
if (x instanceof List<?>) {
List<?> list = (List<?>) x;
// do something with list
} else if (x instanceof Collection<?>) {
Collection<?> col = (Collection<?>) x;
// do something with col
}
One thing should be mentioned here: it's important in these kinds of constructs to check in the right order. You will find that if you had swapped the order of the check in the above snippet, the code will still compile, but it will no longer work. That is the following code doesn't work:
// DOESN'T WORK! Wrong order!
if (x instanceof Collection<?>) {
Collection<?> col = (Collection<?>) x;
// do something with col
} else if (x instanceof List<?>) { // this will never be reached!
List<?> list = (List<?>) x;
// do something with list
}
The problem is that a List<?>
is-a Collection<?>
, so it will pass the first test, and the else
means that it will never reach the second test. You have to test from the most specific to the most general type.
I'd strongly suggest moving away from inline JavaScript, to something like the following:
function redirect(goto){
var conf = confirm("Are you sure you want to go elswhere?");
if (conf && goto != '') {
window.location = goto;
}
}
var selectEl = document.getElementById('redirectSelect');
selectEl.onchange = function(){
var goto = this.value;
redirect(goto);
};
JS Fiddle demo (404 linkrot victim).
JS Fiddle demo via Wayback Machine.
Forked JS Fiddle for current users.
In the mark-up in the JS Fiddle the first option has no value assigned, so clicking it shouldn't trigger the function to do anything, and since it's the default value clicking the select
and then selecting that first default option
won't trigger the change
event anyway.
Update:
The latest example's (2017-08-09) redirect URLs required swapping out due to errors regarding mixed content between JS Fiddle and both domains, as well as both domains requiring 'sameorigin' for framed content. - Albert
If you have already pushed the wrong name to remote, do the following:
Switch to the local branch you want to rename
git checkout <old_name>
Rename the local branch
git branch -m <new_name>
Push the <new_name>
local branch and reset the upstream branch
git push origin -u <new_name>
Delete the <old_name>
remote branch
git push origin --delete <old_name>

When you insert ANY variable into HTML, unless you want the browser to interpret the variable itself as HTML, it's best to use htmlspecialchars()
on it. Among other things, it prevents hackers from inserting arbitrary HTML in your page.
The value of $_SERVER['PHP_SELF']
is taken directly from the URL entered in the browser. Therefore if you use it without htmlspecialchars()
, you're allowing hackers to directly manipulate the output of your code.
For example, if I e-mail you a link to http://example.com/"><script>malicious_code_here()</script><span class="
and you have <form action="<?php echo $_SERVER['PHP_SELF'] ?>">
, the output will be:
<form action="http://example.com/"><script>malicious_code_here()</script><span class="">
My script will run, and you will be none the wiser. If you were logged in, I may have stolen your cookies, or scraped confidential info from your page.
However, if you used <form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']) ?>">
, the output would be:
<form action="http://example.com/"><script>cookie_stealing_code()</script><span class="">
When you submitted the form, you'd have a weird URL, but at least my evil script did not run.
On the other hand, if you used <form action="">
, then the output would be the same no matter what I added to my link. This is the option I would recommend.
x = float(raw_input("enter number between 0 and 1: "))
p = 0
while ((2**p)*x) %1 != 0:
p += 1
# print p
num = int (x * (2 ** p))
# print num
result = ''
if num == 0:
result = '0'
while num > 0:
result = str(num%2) + result
num = num / 2
for i in range (p - len(result)):
result = '0' + result
result = result[0:-p] + '.' + result[-p:]
print result #this will print result for the decimal portion
If you're running a jar file with java -jar
, the -classpath
argument is ignored. You need to set the classpath in the manifest file of your jar, like so:
Class-Path: jar1-name jar2-name directory-name/jar3-name
See the Java tutorials: Adding Classes to the JAR File's Classpath.
Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':
' after "Class-Path
" like you showed, it would not work.
If you're not set on rolling your own solution, check out this jQuery plugin:

It will do that and more for you. It's highly recommended.
Here's a minimal working example which works for Angular 1.0.2
Template:
<script type="text/ng-template" id="/editor-tpl.html">
Editor Template {{datasets}}
</script>
<div ng-view>
</div>
JavaScript:
function MyCtrl($scope, datasets) {
$scope.datasets = datasets;
}
MyCtrl.resolve = {
datasets : function($q, $http) {
var deferred = $q.defer();
$http({method: 'GET', url: '/someUrl'})
.success(function(data) {
deferred.resolve(data)
})
.error(function(data){
//actually you'd want deffered.reject(data) here
//but to show what would happen on success..
deferred.resolve("error value");
});
return deferred.promise;
}
};
var myApp = angular.module('myApp', [], function($routeProvider) {
$routeProvider.when('/', {
templateUrl: '/editor-tpl.html',
controller: MyCtrl,
resolve: MyCtrl.resolve
});
});?
?
Streamlined version:
Since $http() already returns a promise (aka deferred), we actually don't need to create our own. So we can simplify MyCtrl. resolve to:
MyCtrl.resolve = {
datasets : function($http) {
return $http({
method: 'GET',
url: 'http://fiddle.jshell.net/'
});
}
};
The result of $http() contains data, status, headers and config objects, so we need to change the body of MyCtrl to:
$scope.datasets = datasets.data;
var dates = dates_as_int.map(function(dateStr) {
return new Date(dateStr).getTime();
});
=>
[1468959781804, 1469029434776, 1469199218634, 1469457574527]
Update: ES6 version:
const dates = dates_as_int.map(date => new Date(date).getTime())
There are two ways to use this variable:
passing it as a command line argument just like Job mentioned:
cmake -DCMAKE_INSTALL_PREFIX=< install_path > ..
assigning value to it in CMakeLists.txt
:
SET(CMAKE_INSTALL_PREFIX < install_path >)
But do remember to place it BEFORE PROJECT(< project_name>)
command, otherwise it will not work!

AsNoTracking() allows the "unique key per record" requirement in EF to be bypassed (not mentioned explicitly by other answers).
This is extremely helpful when reading a View that does not support a unique key because perhaps some fields are nullable or the nature of the view is not logically indexable.
For these cases the "key" can be set to any non-nullable column but then AsNoTracking() must be used with every query else records (duplicate by key) will be skipped.
As I posted here gcc can create dependencies and compile at the same time:
DEPS := $(OBJS:.o=.d)
-include $(DEPS)
%.o: %.c
$(CC) $(CFLAGS) -MM -MF $(patsubst %.o,%.d,$@) -o $@ $<
The '-MF' parameter specifies a file to store the dependencies in.
The dash at the start of '-include' tells Make to continue when the .d file doesn't exist (e.g. on first compilation).
Note there seems to be a bug in gcc regarding the -o option. If you set the object filename to say obj/_file__c.o then the generated file.d will still contain file.o, not obj/_file__c.o.
Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable

Character sets will help out a ton here. You want to create a matching set for the characters that you want to validate:
\w
, which is the same as [A-Za-z0-9_]
in JavaScript (other languages can differ).-
and spaces, which can be combined into a matching set such as [\w\- ]
. However, you may want to consider using \s
instead of just the space character (\s
also matches tabs, and other forms of whitespace)
-
as \-
so that the regex engine doesn't confuse it with a character range like A-Z
^
and $
The full regex you're probably looking for is:
/^[\w\-\s]+$/
(Note that the +
indicates that there must be at least one character for it to match; use a *
instead, if a zero-length string is also ok)
Finally, http://www.regular-expressions.info/ is an awesome reference
Bonus Points: This regex does not match non-ASCII alphas. Unfortunately, the regex engine in most browsers does not support named character sets, but there are some libraries to help with that.
For languages/platforms that do support named character sets, you can use /^[\p{Letter}\d\_\-\s]+$/

Google TOS have been relaxed a bit in April 2014. Now it states:
"Don’t misuse our Services. For example, don’t interfere with our Services or try to access them using a method other than the interface and the instructions that we provide."
So the passage about "automated means" and scripts is gone now. It evidently still is not the desired (by google) way of accessing their services, but I think it is now formally open to interpretation of what exactly an "interface" is and whether it makes any difference as of how exactly returned HTML is processed (rendered or parsed). Anyhow, I have written a Java convenience library and it is up to you to decide whether to use it or not:
You can't achieve text size change with a state list drawable. To change text color and text size do this:
Text color
To change the text color, you can create color state list resource. It will be a separate resource located in res/color/
directory. In layout xml you have to set it as the value for android:textColor
attribute. The color selector will then contain something like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="@color/text_pressed" />
<item android:color="@color/text_normal" />
</selector>
Text size
You can't change the size of the text simply with resources. There's no "dimen selector". You have to do it in code. And there is no straightforward solution.
Probably the easiest solution might be utilizing View.onTouchListener()
and handle the up and down events accordingly. Use something like this:
view.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// change text size to the "pressed value"
return true;
case MotionEvent.ACTION_UP:
// change text size to the "normal value"
return true;
default:
return false;
}
}
});
A different solution might be to extend the view and override the setPressed(Boolean)
method. The method is internally called when the change of the pressed state happens. Then change the size of the text accordingly in the method call (don't forget to call the super).

I found an article about how to move svn repositories from a hosting service to another, and how to do local backups:
Define where you will store your repositories:
mkdir ~/repo
MYREPO=/home/me/someplace ## you should use full path here
svnadmin create $MYREPO
Create a hook file and make it executable:
echo '#!/bin/sh' > $MYREPO/hooks/pre-revprop-change
chmod +x $MYREPO/hooks/pre-revprop-change
Now we can start importing the repository with svnsync
, that will initialize a destination repository for synchronization from another repository:
svnsync init file://$MYREPO http://your.svn.repo.here/
And the finishing touch to transfer all pending revisions to the destination from the source with which it was initialized:
svnsync sync file://$MYREPO
There now you have a local svn repository in the ~/repo
directory.
Source:

1 - Open the files '.vbox' and '.vbox-prev' (if exist) files in any text editor and replace the first character of HardDisk uuid (take note to revert this change on step 6)
Example: nano /home/virtualbox/WindowsServer/WindowsServer.vbox
Change:
<HardDisks>
<HardDisk uuid="{3ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>
To:
<HardDisks>
<HardDisk uuid="{2ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>
2 - Reboot machine
4 - Stop Virtual Machine (if started)
5 - On terminal:
su vbox
cd /home/virtualbox/WindowsServer/
VBoxManage modifyhd WindowsServer.vdi --resize SIZE
exit
exit
change SIZE for a number in Megabytes, example 80000 (80GB)
6 - Open again the files '.vbox' and '.vbox-prev' (if exist) files in any text editor and replace the first character of HardDisk uuid whith the original value
Example: nano /home/virtualbox/WindowsServer/WindowsServer.vbox
Change:
<HardDisks>
<HardDisk uuid="{2ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>
To:
<HardDisks>
<HardDisk uuid="{3ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>

I wrote this simple function to produce this format: 01:00:03
Seconds are always shown (even if zero). Minutes are shown if greater than zero or if hours or days are required. Hours are shown if greater than zero or if days are required. Days are shown if greater than zero.
function formatSeconds($secs) {
$result = '';
$seconds = intval($secs) % 60;
$minutes = (intval($secs) / 60) % 60;
$hours = (intval($secs) / 3600) % 24;
$days = intval(intval($secs) / (3600*24));
if ($days > 0) {
$result = str_pad($days, 2, '0', STR_PAD_LEFT) . ':';
}
if(($hours > 0) || ($result!="")) {
$result .= str_pad($hours, 2, '0', STR_PAD_LEFT) . ':';
}
if (($minutes > 0) || ($result!="")) {
$result .= str_pad($minutes, 2, '0', STR_PAD_LEFT) . ':';
}
//seconds aways shown
$result .= str_pad($seconds, 2, '0', STR_PAD_LEFT);
return $result;
} //funct
Examples:
echo formatSeconds(15); //15
echo formatSeconds(100); //01:40
echo formatSeconds(10800); //03:00:00 (mins shown even if zero)
echo formatSeconds(10000000); //115:17:46:40
You want the php function "asort":
http://php.net/manual/en/function.asort.php
it sorts the array, maintaining the index associations.
Edit: I've just noticed you're using a standard array (non-associative). if you're not fussed about preserving index associations, use sort():
The problem may be that directive is not under < Directory>
https://httpd.apache.org/docs/2.4/mod/mod_authz_host.html#requiredirectives
The directive can be referenced within a < Directory>, < Files>, or < Location> section as well as .htaccess files to control access to particular parts of the server. Access can be controlled based on the client hostname or IP address.
I suggest another way to solve to this problem. The idea is wrapping your viewPager by a scrollView, so that when this scrollView is non-scrollable, your viewPager is non-scrollable too.
Here is my XML layout:
<HorizontalScrollView
android:id="@+id/horizontalScrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</HorizontalScrollView>
No code needed.
Works fine for me.

An alternative to theme_classic()
is the theme that comes with the cowplot package, theme_cowplot()
(loaded automatically with the package). It looks similar to theme_classic()
, with a few subtle differences. Most importantly, the default label sizes are larger, so the resulting figures can be used in publications without further modifications needed (in particular if you save them with save_plot()
instead of ggsave()
). Also, the background is transparent, not white, which may be useful if you want to edit the figure in illustrator. Finally, faceted plots look better, in my opinion.
Example:
library(cowplot)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))
p <- ggplot(df, aes(x = a, y = b)) + geom_point()
save_plot('plot.png', p) # alternative to ggsave, with default settings that work well with the theme
This is what the file plot.png
produced by this code looks like:

If you are looking for a solution that works in node.js, you can use this:
var myBuffer = [];
var str = 'Stack Overflow';
var buffer = new Buffer(str, 'utf16le');
for (var i = 0; i < buffer.length; i++) {
myBuffer.push(buffer[i]);
}
console.log(myBuffer);
A sort of block comment uses an if statement:
if(FALSE) {
all your code
}
It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).
If you're only worried about the first letter of the first word being capitalized:
private String capitalize(final String line) {
return Character.toUpperCase(line.charAt(0)) + line.substring(1);
}
Okay, it is going to be extremely late answer to this question. But here is just one sample if you want to do it in Kotlin.
val intent = Intent(Intent.ACTION_DIAL)
intent.data = Uri.parse("tel:<number>")
startActivity(intent)
Thought it might help someone.
I agree with the use of instanceof
already mentioned.
An additional benefit of using instanceof
is that when used with a null
reference instanceof
of will return false
, while a.getClass()
would throw a NullPointerException
.
A bundled stylesheet may save page load performance but the more styles there are the slower the browser renders animations on the page you are on. This is caused by the huge amount of unused styles that may not be on the page you are on but the browser still has to calculate.
See: https://benfrain.com/css-performance-revisited-selectors-bloat-expensive-styles/
Bundled stylesheets advantages: - page load performance
Bundled stylesheets disadvantages: - slower behaviour, which can cause choppyness during scrolling, interactivity, animation,
Conclusion: To solve both problems, for production the ideal solution is to bundle all the css into one file to save on http requests, but use javascript to extract from that file, the css for the page you are on and update the head with it.
To know which shared components are needed per page, and to reduce complexity, it would be nice to have declared all the components this particular page uses - for example:
<style href="global.css" rel="stylesheet"/>
<body data-shared-css-components="x,y,z">
If I understand, what you want to do is disregard the orientation of the UIImage? If so then you could do this:
UIImage *originalImage = [... whatever ...];
UIImage *imageToDisplay =
[UIImage imageWithCGImage:[originalImage CGImage]
scale:[originalImage scale]
orientation: UIImageOrientationUp];
So you're creating a new UIImage with the same pixel data as the original (referenced via its CGImage property) but you're specifying an orientation that doesn't rotate the data.
Today I faced with the same problem. As the result of the first run I got next error:
Lexical or Preprocessor Issue: 'SDKProjectName*/*SDKProjectName.h' file not found.
But before running, I, obviously, added my SDK into the demo project, just drag&drop .xcodeproj file into my test project's source tree. After that, I moved into Build Phases tab in setting of the main xcodeproj file (of the demo) and added my SDK as target dependency and embed framework into corresponding tabs.
But at the result, I got an error above!
So, the problem was into empty line on the Header Search Paths option. I just wrote "../**"
as value for this key and project compiled successfully. So, after that, you can add #include <SDKName/SDKName.h>
into any project, which includes this SDK.
ps. My test app was created into root SDK folder.
I wrote some lines of code to automatically tweak all things powertop suggests when I unplug my laptop and undo that if I plug the laptop back in. Maximum power, maximum efficiency, maximum convenience.
You should not wrap JavaScript expressions in quotes.
<option data-img-src={this.props.imageUrl} value="1">{this.props.title}</option>
Take a look at the JavaScript Expressions docs for more info.
This worked for me fine:
File 1:
<html>
<head></head>
<body>
<a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
</body>
<footer></footer>
</html>
File 2:
<html>
...
</html>
This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.
For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.
I need to know way for converting uri to string and string to uri.
Use toString()

. A Uri
has a scheme, and "/external/images/media/470939"
does not have a scheme.

These answers are fine for debugging, but for programmatically testing the exception, isinstance(e, SomeException)
can be handy, as it tests for subclasses of SomeException
too, so you can create functionality that applies to hierarchies of exceptions.
I had quite a bit of trouble as I didn't want to FIX the overlay in place as I wanted the info inside the overlay to be scrollable over the text. I used:
<html style="height=100%">
<body style="position:relative">
<div id="my-awesome-overlay"
style="position:absolute;
height:100%;
width:100%;
display: block">
[epic content here]
</div>
</body>
</html>
Of course the div in the middle needs some content and probably a transparent grey background but I'm sure you get the gist!
Use the ALLOW_PAGE_LOCKS clause of ALTER/CREATE INDEX:
ALTER INDEX indexname ON tablename SET (ALLOW_PAGE_LOCKS = OFF);
cd
to the repository then
find . -name ".git*" -exec rm -R {} \;
Make sure not to accidentally pipe a single dot, slash, asterisk, or other regex wildcard into find, or else rm
will happily delete it.
An easy fix to this question is to add '[' in the start of your json file, and ending it with a ']'. This solved it for me.

If I know the database is MySQL, I'll use the NOW() function like this:

I take it you're on Mac. See How can I install PIL on mac os x 10.7.2 Lion
If you use [homebrew][], you can install the PIL with just
brew install pil
. You may then need to add the install directory ($(brew --prefix)/lib/python2.7/site-packages
) to your PYTHONPATH, or add the location of PIL directory itself in a file calledPIL.pth
file in any of your site-packages directories, with the contents:/usr/local/lib/python2.7/site-packages/PIL
(assuming
brew --prefix
is/usr/local
).Alternatively, you can just download/build/install it from source:
# download curl -O -L http://effbot.org/media/downloads/Imaging-1.1.7.tar.gz # extract tar -xzf Imaging-1.1.7.tar.gz cd Imaging-1.1.7 # build and install python setup.py build sudo python setup.py install # or install it for just you without requiring admin permissions: # python setup.py install --user
I ran the above just now (on OSX 10.7.2, with XCode 4.2.1 and System Python 2.7.1) and it built just fine, though there is a possibility that something in my environment is non-default.

Well, maybe an int

Try:
len(str(numbers))
Unique pointers are guaranteed to destroy the object they manage when they go out of scope. http://en.cppreference.com/w/cpp/memory/unique_ptr
In this case:
unique_ptr<double> uptr2 (pd);
pd
will be destroyed when uptr2
goes out of scope. This facilitates memory management by automatic deletion.
The case of unique_ptr<int> uptr (new int(3));
is not different, except that the raw pointer is not assigned to any variable here.

In addition to the other answers, a further example of the variability of word size (from one system to the next) is in the paper Smashing The Stack For Fun And Profit by Aleph One:
We must remember that memory can only be addressed in multiples of the word size. A word in our case is 4 bytes, or 32 bits. So our 5 byte buffer is really going to take 8 bytes (2 words) of memory, and our 10 byte buffer is going to take 12 bytes (3 words) of memory.
In my case, I needed to retrieve the username to enable the script to change the path, ie. c:\users\%username%\
. I needed to start the script by changing the path to the users desktop. I was able to do this, with help from above and elsewhere, by using the get-location applet.
You may have another, or even better way to do it, but this worked for me:
$Path = Get-Location
Set-Location $Path\Desktop
This code will add an event listener to the default local Inbox, then take some action on incoming emails. You need to add that action in the code below.
Private WithEvents Items As Outlook.Items
Private Sub Application_Startup()
Dim olApp As Outlook.Application
Dim objNS As Outlook.NameSpace
Set olApp = Outlook.Application
Set objNS = olApp.GetNamespace("MAPI")
' default local Inbox
Set Items = objNS.GetDefaultFolder(olFolderInbox).Items
End Sub
Private Sub Items_ItemAdd(ByVal item As Object)
On Error Goto ErrorHandler
Dim Msg As Outlook.MailItem
If TypeName(item) = "MailItem" Then
Set Msg = item
' ******************
' do something here
' ******************
End If
ProgramExit:
Exit Sub
ErrorHandler:
MsgBox Err.Number & " - " & Err.Description
Resume ProgramExit
End Sub
After pasting the code in ThisOutlookSession
module, you must restart Outlook.
If you have a lot of relation attribute fields to use in list_display
and do not want create a function (and it's attributes) for each one, a dirt but simple solution would be override the ModelAdmin
instace __getattr__
method, creating the callables on the fly:
class DynamicLookupMixin(object):
'''
a mixin to add dynamic callable attributes like 'book__author' which
return a function that return the instance.book.author value
'''
def __getattr__(self, attr):
if ('__' in attr
and not attr.startswith('_')
and not attr.endswith('_boolean')
and not attr.endswith('_short_description')):
def dyn_lookup(instance):
# traverse all __ lookups
return reduce(lambda parent, child: getattr(parent, child),
attr.split('__'),
instance)
# get admin_order_field, boolean and short_description
dyn_lookup.admin_order_field = attr
dyn_lookup.boolean = getattr(self, '{}_boolean'.format(attr), False)
dyn_lookup.short_description = getattr(
self, '{}_short_description'.format(attr),
attr.replace('_', ' ').capitalize())
return dyn_lookup
# not dynamic lookup, default behaviour
return self.__getattribute__(attr)
# use examples
@admin.register(models.Person)
class PersonAdmin(admin.ModelAdmin, DynamicLookupMixin):
list_display = ['book__author', 'book__publisher__name',
'book__publisher__country']
# custom short description
book__publisher__country_short_description = 'Publisher Country'
@admin.register(models.Product)
class ProductAdmin(admin.ModelAdmin, DynamicLookupMixin):
list_display = ('name', 'category__is_new')
# to show as boolean field
category__is_new_boolean = True
As gist here
Callable especial attributes like boolean
and short_description
must be defined as ModelAdmin
attributes, eg book__author_verbose_name = 'Author name'
and category__is_new_boolean = True
.
The callable admin_order_field
attribute is defined automatically.
Don't forget to use the list_select_related attribute in your ModelAdmin
to make Django avoid aditional queries.
The class which implements KeyListener
interface becomes our custom key event listener. This listener can not directly listen the key events. It can only listen the key events through intermediate objects such as JFrame
. So
Make one Key listener class as
class MyListener implements KeyListener{
// override all the methods of KeyListener interface.
}
Now our class MyKeyListener
is ready to listen the key events. But it can not directly do so.
Create any object like JFrame
object through which MyListener
can listen the key events. for that you need to add MyListener
object to the JFrame
object.
JFrame f=new JFrame();
f.addKeyListener(new MyKeyListener);
There's a difference between C++ and C# in this specific case. In C++ the object is not initialized and therefore it is unsafe to call a virutal function inside a constructor. In C# when a class object is created all its members are zero initialized. It is possible to call a virtual function in the constructor but if you'll might access members that are still zero. If you don't need to access members it is quite safe to call a virtual function in C#.
I was surprised that no other answers on this page mentioned git stash push
.
This article helped me understand:
The command
git stash
is shorthand forgit stash push
. In this mode, non-option arguments are not allowed to prevent a misspelled subcommand from making an unwanted stash entry. There are also another alias for this commandgit stash save
which is deprecated in favour ofgit stash push
.By default git ignores untracked files when doing stash. If those files need to be added to stash you can use
-u
options which tells git to include untracked files. Ignored files can be added as well if-a
option is specified.-a
will include both untracked and ignored files.
I care about naming my stashes, and I want them to include untracked files, so the command I most commonly run is: git stash push -u -m "whatIWantToNameThisStash"
As of v1.1.0-alpha1 (pre release package) the framework uses the VirtualPathProvider
to access files rather than touching the physical file system.
The updated transformer can be seen below:
public class StyleRelativePathTransform
: IBundleTransform
{
public void Process(BundleContext context, BundleResponse response)
{
Regex pattern = new Regex(@"url\s*\(\s*([""']?)([^:)]+)\1\s*\)", RegexOptions.IgnoreCase);
response.Content = string.Empty;
// open each of the files
foreach (var file in response.Files)
{
using (var reader = new StreamReader(file.Open()))
{
var contents = reader.ReadToEnd();
// apply the RegEx to the file (to change relative paths)
var matches = pattern.Matches(contents);
if (matches.Count > 0)
{
var directoryPath = VirtualPathUtility.GetDirectory(file.VirtualPath);
foreach (Match match in matches)
{
// this is a path that is relative to the CSS file
var imageRelativePath = match.Groups[2].Value;
// get the image virtual path
var imageVirtualPath = VirtualPathUtility.Combine(directoryPath, imageRelativePath);
// convert the image virtual path to absolute
var quote = match.Groups[1].Value;
var replace = String.Format("url({0}{1}{0})", quote, VirtualPathUtility.ToAbsolute(imageVirtualPath));
contents = contents.Replace(match.Groups[0].Value, replace);
}
}
// copy the result into the response.
response.Content = String.Format("{0}\r\n{1}", response.Content, contents);
}
}
}
}
Use the SC

TL;DR: All well written web sites (/apps) must emit the header X-XSS-Protection: 0
and just forget about this feature. If you want to have extra security that better user agents can provide, use a strict Content-Security-Policy
header.
Long answer:
HTTP header X-XSS-Protection
is one of those things that Microsoft introduced in Internet Explorer 8.0 (MSIE 8) that was supposed to improve security of incorrectly written web sites.
The idea is to apply some kind of heuristics to try to detect reflection XSS attack and automatically neuter the attack.
The problematic part of this is "heuristics" and "neutering". The heuristics causes false positives and neutering cannot be safely done because it causes side-effects that can be used to implement XSS attacks and DoS attacks on perfectly safe web sites.
The bad part is that if a web site does not emit the header X-XSS-Protection
then the browser will behave as if the header X-XSS-Protection: 1
had been emitted. The worst part is that this value is the least-safe value of all possible values for this header!
For a given secure web site (that is, the site does not have reflected XSS vulnerabilities) this "XSS protection" feature allows following attacks:
X-XSS-Protection: 1
allows attacker to selectively block parts of JavaScript and keep rest of the scripts running. This is possible because the heuristics of this feature are simply "if value of any GET parameter is found in the scripting part of the page source, the script will be automatically modified in user agent dependant way". In practice, the attacker can e.g. add parameter disablexss=<script src="framebuster.js"
and the browser will automatically remove the string <script src="framebuster.js"
from the actual page source. Note that the rest of the page continues run and the attacker just removed this part of page security. In practice, any JS in the page source can be modified. For some cases, a page without XSS vulnerability having reflected content can be used to run selected JavaScript on page due the neutering incorrectly turning plain text data into executable JavaScript code. (That is, turn textual data within a normal DOM text node into content of <script>
tag and execute it!)
X-XSS-Protection: 1; mode=block
allows attacker to leak data from the page source by using the behavior of the page as side-channel. For example, if the page contains JavaScript code along the lines of var csrf_secret="521231347843"
, the attacker simply adds an extra parameter e.g. leak=var%20csrf_secret="3
and if the page is NOT blocked, the 3
was incorrect first digit. The attacker tries again, this time leak=var%20csrf_secret="5
and the page loading will be aborted. This allows the attacker to know that the first digit of the secret is 5
. The attacker then continues to guess the next digit. This allows easily brute-forcing of CSRF secrets or any other secret value in the <script>
source.
In the end, if your site is full of XSS reflection attacks, using the default value of 1
will reduce the attack surface a little bit. However, if your site is secure and you don't emit X-XSS-Protection: 0
, your site will be vulnerable with any browser that supports this feature. If you want defense in depth support from browsers against yet-unknown XSS vulnerabilities on your site, use a strict Content-Security-Policy
header and keep sending 0
for this mis-feature. That doesn't open your site to any known vulnerabilities.
Currently this feature is enabled by default in MSIE, Safari and Google Chrome. This used to be enabled in Edge but Microsoft already removed this mis-feature from Edge. Mozilla Firefox never implemented this.

Unsigned int can be converted to signed (or vice-versa) by simple expression as shown below :
unsigned int z;
int y=5;
z= (unsigned int)y;
Though not targeted to the question, you would like to read following links :
x = list(1, 2, 3, 4)
x2 = list(1:4)
all.equal(x,x2)
is not the same because 1:4 is the same as c(1,2,3,4). If you want them to be the same then:
x = list(c(1,2,3,4))
x2 = list(1:4)
all.equal(x,x2)

Try this its working for me.
private static async Task<object> Upload(string actionUrl)
{
Image newImage = Image.FromFile(@"Absolute Path of image");
ImageConverter _imageConverter = new ImageConverter();
byte[] paramFileStream= (byte[])_imageConverter.ConvertTo(newImage, typeof(byte[]));
var formContent = new MultipartFormDataContent
{
// Send form text values here
{new StringContent("value1"),"key1"},
{new StringContent("value2"),"key2" },
// Send Image Here
{new StreamContent(new MemoryStream(paramFileStream)),"imagekey","filename.jpg"}
};
var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(actionUrl.ToString(), formContent);
string stringContent = await response.Content.ReadAsStringAsync();
return response;

Your code works for me.
$input = 201308131830;
echo date("Y-M-d H:i:s",strtotime($input)) . "\n";
echo date("D", strtotime($input)) . "\n";
Output:
2013-Aug-13 18:30:00
Tue
However if you pass 201308131830
as a number it is 50 to 100x larger than can be represented by a 32-bit integer. [dependent on your system's specific implementation] If your server/PHP version does not support 64-bit integers then the number will overflow and probably end up being output as a negative number and date()
will default to Jan 1, 1970 00:00:00 GMT
.
Make sure whatever source you are retrieving this data from returns that date as a string, and keep it as a string.
First give your input type submit a name, like this name='submitform'
.
and then put this in your php file
if (isset($_POST['submitform']))
{
?>
<script type="text/javascript">
window.location = "http://www.google.com/";
</script>
<?php
}
Don't forget to change the url to yours.
You can add your own css property for button size as follows:

Try an LL
suffix on the number, the compiler may be casting it to an intermediate type as part of the parse. See http://gcc.gnu.org/onlinedocs/gcc/Long-Long.html
long long int i2 = 0x0000444400004444LL;
Additionally, the the compiler is discarding the leading zeros, so 0x000044440000
is becoming 0x44440000
, which is a perfectly acceptable 32-bit integer (which is why you aren't seeing any warnings prior to f2
).
encodeURIComponent/decodeURIComponent() is almost always the pair you want to use, for concatenating together and splitting apart text strings in URI parts.
encodeURI in less common, and misleadingly named: it should really be called fixBrokenURI. It takes something that's nearly a URI, but has invalid characters such as spaces in it, and turns it into a real URI. It has a valid use in fixing up invalid URIs from user input, and it can also be used to turn an IRI (URI with bare Unicode characters in) into a plain URI (using %-escaped UTF-8 to encode the non-ASCII).
decodeURI decodes the same characters as decodeURIComponent except for a few special ones. It is provided to be an inverse of encodeURI, but you still can't count on it to return the same as you originally put in — see eg. decodeURI(encodeURI('%20 '));
.
Where encodeURI should really be named fixBrokenURI(), decodeURI() could equally be called potentiallyBreakMyPreviouslyWorkingURI(). I can think of no valid use for it anywhere; avoid.
The results of the execution time directly contradict the results of the Query Cost, but I'm having difficulty determining what "Query Cost" actually means.
Query cost
is what optimizer thinks of how long your query will take (relative to total batch time).
The optimizer tries to choose the optimal query plan by looking at your query and statistics of your data, trying several execution plans and selecting the least costly of them.
Here you may read in more detail about how does it try to do this.
As you can see, this may differ significantly of what you actually get.
The only real query perfomance metric is, of course, how long does the query actually take.
After a lot of searching, the best explanation I've found is from Java Performance Tuning website in Question of the month: 1.4.1 Garbage collection algorithms, January 29th, 2003
Young generation garbage collection algorithms
The (original) copying collector (Enabled by default). When this collector kicks in, all application threads are stopped, and the copying collection proceeds using one thread (which means only one CPU even if on a multi-CPU machine). This is known as a stop-the-world collection, because basically the JVM pauses everything else until the collection is completed.
The parallel copying collector (Enabled using -XX:+UseParNewGC). Like the original copying collector, this is a stop-the-world collector. However this collector parallelizes the copying collection over multiple threads, which is more efficient than the original single-thread copying collector for multi-CPU machines (though not for single-CPU machines). This algorithm potentially speeds up young generation collection by a factor equal to the number of CPUs available, when compared to the original singly-threaded copying collector.
The parallel scavenge collector (Enabled using -XX:UseParallelGC). This is like the previous parallel copying collector, but the algorithm is tuned for gigabyte heaps (over 10GB) on multi-CPU machines. This collection algorithm is designed to maximize throughput while minimizing pauses. It has an optional adaptive tuning policy which will automatically resize heap spaces. If you use this collector, you can only use the the original mark-sweep collector in the old generation (i.e. the newer old generation concurrent collector cannot work with this young generation collector).
From this information, it seems the main difference (apart from CMS cooperation) is that UseParallelGC supports ergonomics while UseParNewGC doesn't.
For internal gridlines, use the tag: td For external gridlines, use the tag: table
The problem is the length of the filenames. The first filename is only 7 chars long, so the tab occurs at char 8 (doing a tab after every 4 characters). However the next filenames are 8 chars long, so the next tab won't be until char 12. And if you had filenames longer than 11 chars, you'd run into the same problem again.
Below is the code that worked for me. We use jpa 1.0, Apache openjpa implementation.
import java.sql.Connection;
import org.apache.openjpa.persistence.OpenJPAEntityManager;
import org.apache.openjpa.persistence.OpenJPAPersistence;
public final class MsSqlDaoFactory {
public static final Connection getConnection(final EntityManager entityManager) {
OpenJPAEntityManager openJPAEntityManager = OpenJPAPersistence.cast(entityManager);
Connection connection = (Connection) openJPAEntityManager.getConnection();
return connection;
}
}
I had the same problem but mine was Due To an Android database memory leak. I skipped a cursor. So the device crashes so as to fix that memory leak. If you are working with the Android database check if you skipped a cursor while retrieving from the database
There are several ways to do this depending on the file format required.
I would use the standard configparser approach unless there were compelling reasons to use a different format.
Write a file like so:
# python 2.x
# from ConfigParser import SafeConfigParser
# config = SafeConfigParser()
# python 3.x
from configparser import ConfigParser
config = ConfigParser()
config.read('config.ini')
config.add_section('main')
config.set('main', 'key1', 'value1')
config.set('main', 'key2', 'value2')
config.set('main', 'key3', 'value3')
with open('config.ini', 'w') as f:
config.write(f)
The file format is very simple with sections marked out in square brackets:
[main]
key1 = value1
key2 = value2
key3 = value3
Values can be extracted from the file like so:
# python 2.x
# from ConfigParser import SafeConfigParser
# config = SafeConfigParser()
# python 3.x
from configparser import ConfigParser
config = ConfigParser()
config.read('config.ini')
print config.get('main', 'key1') # -> "value1"
print config.get('main', 'key2') # -> "value2"
print config.get('main', 'key3') # -> "value3"
# getfloat() raises an exception if the value is not a float
a_float = config.getfloat('main', 'a_float')
# getint() and getboolean() also do this for their respective types
an_int = config.getint('main', 'an_int')
JSON data can be very complex and has the advantage of being highly portable.
Write data to a file:
import json
config = {"key1": "value1", "key2": "value2"}
with open('config1.json', 'w') as f:
json.dump(config, f)
Read data from a file:
import json
with open('config.json', 'r') as f:
config = json.load(f)
#edit the data
config['key3'] = 'value3'
#write it back to the file
with open('config.json', 'w') as f:
json.dump(config, f)
A basic YAML example is provided in this answer. More details can be found on the pyYAML website.
I don't think WPF supports what you are trying to achieve i.e. assigning method to a button using method's name or btn1.Click = "btn1_Click". You will have to use approach suggested in above answers i.e. register button click event with appropriate method btn1.Click += btn1_Click;
Clustered Index
Clustered indexes sort and store the data rows in the table or view based on their key values. These are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be sorted in only one order.
The only time the data rows in a table are stored in sorted order is when the table contains a clustered index. When a table has a clustered index, the table is called a clustered table. If a table has no clustered index, its data rows are stored in an unordered structure called a heap.
Nonclustered
Nonclustered indexes have a structure separate from the data rows. A nonclustered index contains the nonclustered index key values and each key value entry has a pointer to the data row that contains the key value. The pointer from an index row in a nonclustered index to a data row is called a row locator. The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table. For a heap, a row locator is a pointer to the row. For a clustered table, the row locator is the clustered index key.
You can add nonkey columns to the leaf level of the nonclustered index to by-pass existing index key limits, and execute fully covered, indexed, queries. For more information, see Create Indexes with Included Columns. For details about index key limits see Maximum Capacity Specifications for SQL Server.
You have to use FirebaseMessagingService()
instead of FirebaseInstanceIdService
If above solutions doesn't work, try to change the default por from 3306, to another one (i.e. 3307)
This is less for @easwee and more for others that might have the same question:
If you do not require support for IE < 10, you can use Flexbox. It's an exciting CSS3 property that unfortunately was implemented in several different versions,; add in vendor prefixes, and getting good cross-browser support suddenly requires quite a few more properties than it should.
With the current, final standard, you would be done with
.container {
display: flex;
}
.container div {
flex: 1;
}
.column_center {
order: 2;
}
That's it. If you want to support older implementations like iOS 6, Safari < 6, Firefox 19 or IE10, this blossoms into
.container {
display: -webkit-box; /* OLD - iOS 6-, Safari 3.1-6 */
display: -moz-box; /* OLD - Firefox 19- (buggy but mostly works) */
display: -ms-flexbox; /* TWEENER - IE 10 */
display: -webkit-flex; /* NEW - Chrome */
display: flex; /* NEW, Spec - Opera 12.1, Firefox 20+ */
}
.container div {
-webkit-box-flex: 1; /* OLD - iOS 6-, Safari 3.1-6 */
-moz-box-flex: 1; /* OLD - Firefox 19- */
-webkit-flex: 1; /* Chrome */
-ms-flex: 1; /* IE 10 */
flex: 1; /* NEW, Spec - Opera 12.1, Firefox 20+ */
}
.column_center {
-webkit-box-ordinal-group: 2; /* OLD - iOS 6-, Safari 3.1-6 */
-moz-box-ordinal-group: 2; /* OLD - Firefox 19- */
-ms-flex-order: 2; /* TWEENER - IE 10 */
-webkit-order: 2; /* NEW - Chrome */
order: 2; /* NEW, Spec - Opera 12.1, Firefox 20+ */
}
Here is an excellent article about Flexbox cross-browser support: Using Flexbox: Mixing Old And New
You can set data to session simply like this in Codeigniter:
$this->load->library('session');
$this->session->set_userdata(array(
'user_id' => $user->uid,
'username' => $user->username,
'groupid' => $user->groupid,
'date' => $user->date_cr,
'serial' => $user->serial,
'rec_id' => $user->rec_id,
'status' => TRUE
));
and you can get it like this:
$u_rec_id = $this->session->userdata('rec_id');
$serial = $this->session->userdata('serial');
If you remove the javascript:
prefix and remove the parts for the unknown ids like 'black_fade'
from your javascript code, this should work in firefox
Condensed example:
<html>
<head>
<script type="text/javascript">
function show_update_profile() {
document.getElementById('div_register').style.height= "500px";
document.getElementById('div_register').style.width= "500px";
document.getElementById('div_register').style.display='block';
return true;
}
</script>
<style>
/* just to show dimensions of div */
#div_register
{
background-color: #cfc;
}
</style>
</head>
<body>
<div id="main">
<input type="button" onclick="show_update_profile();" value="show"/>
</div>
<div id="div_register">
<table>
<tr>
<td>
welcome
</td>
</tr>
</table>
</div>
</body>
</html>
SELECT DATEADD(minute, -15, '2000-01-01 08:30:00');
The second value (-15 in this case) must be numeric (i.e. not a string like '00:15'). If you need to subtract hours and minutes I would recommend splitting the string on the : to get the hours and minutes and subtracting using something like
SELECT DATEADD(minute, -60 * @h - @m, '2000-01-01 08:30:00');
where @h is the hour part of your string and @m is the minute part of your string
EDIT:
Here is a better way:
SELECT CAST('2000-01-01 08:30:00' as datetime) - CAST('00:15' AS datetime)
It entirely depends upon the Certificate Authority who issuing a certificate.
As far as Let's Encrypt CA, they wont issue TLS certificate on public IP address. https://community.letsencrypt.org/t/certificate-for-public-ip-without-domain-name/6082
To know your Certificate authority , you can execute following command and look for an entry marked below.
curl -v -u <username>:<password> "https://IPaddress/.."
in the html :
<div ng-repeat="t in getTimes(4)">text</div>
and in the controller :
$scope.getTimes=function(n){
return new Array(n);
};
http://plnkr.co/edit/j5kNLY4Xr43CzcjM1gkj
EDIT :
with angularjs > 1.2.x
<div ng-repeat="t in getTimes(4) track by $index">TEXT</div>
Add the line below in application.properties file under resource folder and restart your application.

I had to install IIS Media Services 4.1 from the Windows Web App Gallery.
Update (using renderer):
Note that the original Renderer service has now been deprecated in favor of Renderer2
as on Renderer2 official doc.
Furthermore, as pointed out by @GünterZöchbauer:
Actually using ElementRef is just fine. Also using ElementRef.nativeElement with Renderer2 is fine. What is discouraged is accessing properties of ElementRef.nativeElement.xxx directly.
You can achieve this by using elementRef
as well as by ViewChild
. however it's not recommendable to use elementRef
due to:
as pointed out by official ng2 documentation.
elementRef
(Direct Access):export class MyComponent {
constructor (private _elementRef : ElementRef) {
this._elementRef.nativeElement.querySelector('textarea').focus();
}
}
ViewChild
(better approach):<textarea #tasknote name="tasknote" [(ngModel)]="taskNote" placeholder="{{ notePlaceholder }}"
style="background-color: pink" (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} </textarea> // <-- changes id to local var
export class MyComponent implements AfterViewInit {
@ViewChild('tasknote') input: ElementRef;
ngAfterViewInit() {
this.input.nativeElement.focus();
}
}
renderer
:export class MyComponent implements AfterViewInit {
@ViewChild('tasknote') input: ElementRef;
constructor(private renderer: Renderer2){
}
ngAfterViewInit() {
//using selectRootElement instead of depreaced invokeElementMethod
this.renderer.selectRootElement(this.input["nativeElement"]).focus();
}
}
For linux/unix OS, you can use the shell syntax
const shell = require('child_process').execSync ;
const currentPath= `/path/to/name.png`;
const newPath= `/path/to/another_name.png`;
shell(`mv ${currentPath} ${newPath}`);
That's it!
I also see that the page loading (performance) takes a long time on using h:commandLink than h:link. h:link is faster compared to h:commandLink
In this line:
const char* cstr2 = ss.str().c_str();
ss.str()
will make a copy of the contents of the stringstream. When you call c_str()
on the same line, you'll be referencing legitimate data, but after that line the string will be destroyed, leaving your char*
to point to unowned memory.
There's no mention of numpy in the question. If by array you mean list, then if you treat a list as a boolean it will yield True if it has items and False if it's empty.
l = []
if l:
print "list has items"
if not l:
print "list is empty"
You can also call the show() function after each plot. e.g
plt.plot(a)
plt.show()
plt.plot(b)
plt.show()
To differentiate between scroll up/down in jQuery, you could use:
var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$('#yourDiv').bind(mousewheelevt, function(e){
var evt = window.event || e //equalize event object
evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible
var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF
if(delta > 0) {
//scroll up
}
else{
//scroll down
}
});
This method also works in divs that have overflow:hidden
.
I successfully tested it in FireFox, IE and Chrome.
This should work
SELECT EXTRACTVALUE(column_name, '/DCResponse/ContextData/Decision') FROM traptabclob;
I have assumed the ** were just for highlighting?
As you might be aware of, Maven is a build automation tool provided by Apache which does more than dependency management. We can make it as a peer of Ant and Makefile which downloads all of the dependencies required.
On a mvn install
, it frames a dependency tree based on the project configuration pom.xml
on all the sub projects under the super pom.xml
(the root POM) and downloads/compiles all the needed components in a directory called .m2
under the user's folder. These dependencies will have to be resolved for the project to be built without any errors, and mvn install
is one utility that could download most of the dependencies.
Further, there are other utils within Maven like dependency:resolve
which can be used separately in any specific cases. The build life cycle of the mvn is as below: LifeCycle Bindings
process-resources
compile
process-test-resources
test-compile
test
package
install
deploy
The test phase of this mvn can be ignored by using a flag -DskipTests=true
.
You can flip it horizontally with CSS...
a:visited {
-moz-transform: scaleX(-1);
-o-transform: scaleX(-1);
-webkit-transform: scaleX(-1);
transform: scaleX(-1);
filter: FlipH;
-ms-filter: "FlipH";
}
If you want to flip vertically instead...
a:visited {
-moz-transform: scaleY(-1);
-o-transform: scaleY(-1);
-webkit-transform: scaleY(-1);
transform: scaleY(-1);
filter: FlipV;
-ms-filter: "FlipV";
}
Per the MSDN documentation for sys.database_permissions, this query lists all permissions explicitly granted or denied to principals in the database you're connected to:
SELECT DISTINCT pr.principal_id, pr.name, pr.type_desc,
pr.authentication_type_desc, pe.state_desc, pe.permission_name
FROM sys.database_principals AS pr
JOIN sys.database_permissions AS pe
ON pe.grantee_principal_id = pr.principal_id;
Per Managing Databases and Logins in Azure SQL Database, the loginmanager and dbmanager roles are the two server-level security roles available in Azure SQL Database. The loginmanager role has permission to create logins, and the dbmanager role has permission to create databases. You can view which users belong to these roles by using the query you have above against the master database. You can also determine the role memberships of users on each of your user databases by using the same query (minus the filter predicate) while connected to them.
When using Docker for Mac Application, it appears that the containers are stored within the VM located at:
~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2
UPDATE (Courtesy of mmorin):
As of Jan 15 2019 it seems there is only this file:
~/Library/Containers/com.docker.docker/Data/vms/0/Docker.raw
that contains the Docker Disk and all the images and containers within it.

Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.
Some operations are quicker than java heap space manager. Delaying operations for some time can free memory space. You can use this method to escape heap size error:
waitForGarbageCollector(new Runnable() {
@Override
public void run() {
// Your operations.
}
});
/**
* Measure used memory and give garbage collector time to free up some
* of the space.
*
* @param callback Callback operations to be done when memory is free.
*/
public static void waitForGarbageCollector(final Runnable callback) {
Runtime runtime;
long maxMemory;
long usedMemory;
double availableMemoryPercentage = 1.0;
final double MIN_AVAILABLE_MEMORY_PERCENTAGE = 0.1;
final int DELAY_TIME = 5 * 1000;
runtime =
Runtime.getRuntime();
maxMemory =
runtime.maxMemory();
usedMemory =
runtime.totalMemory() -
runtime.freeMemory();
availableMemoryPercentage =
1 -
(double) usedMemory /
maxMemory;
if (availableMemoryPercentage < MIN_AVAILABLE_MEMORY_PERCENTAGE) {
try {
Thread.sleep(DELAY_TIME);
} catch (InterruptedException e) {
e.printStackTrace();
}
waitForGarbageCollector(
callback);
} else {
// Memory resources are available, go to next operation:
callback.run();
}
}
Though this thread is old but still, I feel I should post a good answer from this stackoverflow answer.
ini_set('display_errors', 1);

Was facing the same issue and unfortunately nothing here was working. Finally, I came across this link: https://blogs.msdn.microsoft.com/jjameson/2009/11/18/the-copy-local-bug-in-visual-studio/
Turns out the solution is sort of dumb: set copy-local for the microsoft.web.infrastructure dll to False, then set it back to True.
By the way, I think what is happening is that there are two versions of the microsoft.web.infrastructure dll, one that is pre-installed in the GAC, and another one that is now a nuget package. I think one is masking the other, hence causing issues. In my particular case, on my build server, I need it to be copied over to a folder (this folder is then zipped and sent off to deployment). I guess the system had a copy locally and just thought "nah, it'll be fine"
... 7 years later, in the desert, a tumbleweed blows by ...
I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone
but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:
Use git svn clone
to clone the last 50 revisions
# -u The SVN URL to clone
# -l The limit of revisions
# -o The output directory
./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt
Find the previous N revision from an SVN repo
# -u The SVN URL to clone
# -l The limit of revisions
./svn-lookback.sh -u https://server/project/trunk -l 5
Probably the best reason is because 0xfffffffffffffff/15
would give you a horribly wrong answer...
For those new to Java and wondering why Jiri's answer doesn't work, make sure you do what he says and handle the exception or else it won't compile. Here's the bare minimum:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class ReadFile {
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new FileReader("test.txt"));
for (String line; (line = br.readLine()) != null;) {
System.out.print(line);
}
br.close()
}
}
There is an alternative to repeating the CONCAT
expression or using subqueries. You can make use of the HAVING
clause, which recognizes column aliases.
SELECT
neededfield, CONCAT(firstname, ' ', lastname) AS firstlast
FROM
users
HAVING firstlast = "Bob Michael Jones"
Here is a working SQL Fiddle.
If you use a website and you fill out a form to submit information (your social security number for example) you want to be sure that the information is being sent to the site you think it's being sent to. So browsers were built to say, by default, 'Do not send information to a domain other than the domain being visited).
Eventually that became too limiting but the default idea still remains in browsers. Don't let the web page send information to a different domain. But this is all browser checking. Chrome and firefox, etc have built in code that says 'before send this request, we're going to check that the destination matches the page being visited'.
Postman (or CURL on the cmd line) doesn't have those built in checks. You're manually interacting with a site so you have full control over what you're sending.
Try the following.
Execute a database backup query from PHP file. Below is an example of using SELECT INTO OUTFILE query for creating table backup:
<?php
$DB_HOST = "localhost";
$DB_USER = "xxx";
$DB_PASS = "xxx";
$DB_NAME = "xxx";
$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if($con->connect_errno > 0) {
die('Connection failed [' . $con->connect_error . ']');
}
$tableName = 'yourtable';
$backupFile = 'backup/yourtable.sql';
$query = "SELECT * INTO OUTFILE '$backupFile' FROM $tableName";
$result = mysqli_query($con,$query);
?>
To restore the backup you just need to run LOAD DATA INFILE query like this:
<?php
$DB_HOST = "localhost";
$DB_USER = "xxx";
$DB_PASS = "xxx";
$DB_NAME = "xxx";
$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if($con->connect_errno > 0) {
die('Connection failed [' . $con->connect_error . ']');
}
$tableName = 'yourtable';
$backupFile = 'yourtable.sql';
$query = "LOAD DATA INFILE 'backupFile' INTO TABLE $tableName";
$result = mysqli_query($con,$query);
?>
Try
mainScrollView.fullScroll(ScrollView.FOCUS_UP);
it should work.
IF there is not only jQuery or other resource killing frameworks - many kb to download each time by each user just for a simple trick - but also native JavaScript(!):
<img src="img1_on.jpg"
onclick="this.src=this.src.match(/_on/)?'img1_off.jpg':'img1_on.jpg';">
<img src="img2_on.jpg"
onclick="this.src=this.src.match(/_on/)?'img2_off.jpg':'img2_on.jpg';">
This can be written general and more elegant:
<html>
<head>
<script>
function switchImg(img){
img.src = img.src.match(/_on/) ?
img.src.replace(/_on/, "_off") :
img.src.replace(/_off/, "_on");
}
</script>
</head>
<body>
<img src="img1_on.jpg" onclick="switchImg(this)">
<img src="img2_on.jpg" onclick="switchImg(this)">
</body>
</html>
You can change the last line to following (assuming you want to return 0 when there is nothing in db):
return OrdersPerHour == null ? 0 : OrdersPerHour.Value;
this is pretty basic stuff, all you need to do is to create a base view model and make sure ALL! and i mean ALL! of your views that will ever use that layout will receive views that use that base model!
public class SomeViewModel : ViewModelBase
{
public bool ImNotEmpty = true;
}
public class EmptyViewModel : ViewModelBase
{
}
public abstract class ViewModelBase
{
}
in the _Layout.cshtml:
@model Models.ViewModelBase
<!DOCTYPE html>
<html>
and so on...
in the the Index (for example) method in the home controller:
public ActionResult Index()
{
var model = new SomeViewModel()
{
};
return View(model);
}
the Index.cshtml:
@model Models.SomeViewModel
@{
ViewBag.Title = "Title";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div class="row">
i disagree that passing a model to the _layout is an error, some user info can be passed and the data can be populate in the controllers inheritance chain so only one implementation is needed.
obviously for more advanced purpose you should consider creating custom static contaxt using injection and include that model namespace in the _Layout.cshtml.
but for basic users this will do the trick
All you have to do is create an object that has the same property names as the results returned by the stored procedure. For the following stored procedure:
CREATE PROCEDURE [dbo].[GetResultsForCampaign]
@ClientId int
AS
BEGIN
SET NOCOUNT ON;
SELECT AgeGroup, Gender, Payout
FROM IntegrationResult
WHERE ClientId = @ClientId
END
create a class that looks like:
public class ResultForCampaign
{
public string AgeGroup { get; set; }
public string Gender { get; set; }
public decimal Payout { get; set; }
}
and then call the procedure by doing the following:
using(var context = new DatabaseContext())
{
var clientIdParameter = new SqlParameter("@ClientId", 4);
var result = context.Database
.SqlQuery<ResultForCampaign>("GetResultsForCampaign @ClientId", clientIdParameter)
.ToList();
}
The result will contain a list of ResultForCampaign
objects. You can call SqlQuery
using as many parameters as needed.
To debug, check server logs if possible. Firefox returns CORS errors in console for a whole range of reasons.
One of the reasons is also uMatrix (and I guess NoScript and similar too) plugin.
Try using ports higher than 3000.
Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like
INSERT INTO HISTORICAL_CAR_STATS (
HISTORICAL_CAR_STATS_ID,
YEAR,
MONTH,
MAKE,
MODEL,
REGION,
AVG_MSRP,
CNT)
SELECT MY_SEQ.nextval,
year,
month,
make,
model,
region,
avg_msrp,
cnt
FROM (SELECT '2010' year,
'12' month,
'ALL' make,
'ALL' model,
REGION,
sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
sum(cnt) cnt
FROM HISTORICAL_CAR_STATS
WHERE YEAR = '2010'
AND MONTH = '12'
AND MAKE != 'ALL'
GROUP BY REGION)
I'm Daniel Stenberg.
I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.
I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.
Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.
Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.
Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.
At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.
Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.
Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?
Yes. So insanely much.
But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.
We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.
Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.
Yeah. For real.
Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.
But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.
curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.
To augment other answers - if you have multiple custom compound views with the same ID and they are all being restored with the state of the last view on a configuration change, all you need to do is tell the view to only dispatch save/restore events to itself by overriding a couple of methods.
class MyCompoundView : ViewGroup {
...
override fun dispatchSaveInstanceState(container: SparseArray<Parcelable>) {
dispatchFreezeSelfOnly(container)
}
override fun dispatchRestoreInstanceState(container: SparseArray<Parcelable>) {
dispatchThawSelfOnly(container)
}
}
For an explanation of what is happening and why this works, see this blog post. Basically your compound view's children's view IDs are shared by each compound view and state restoration gets confused. By only dispatching state for the compound view itself, we prevent their children from getting mixed messages from other compound views.
I did not try this, but what happens when you use :status
twice to check for NULL
?
Query query = getSession().createQuery(
"from CountryDTO c where ( c.status = :status OR ( c.status IS NULL AND :status IS NULL ) ) and c.type =:type"
)
.setParameter("status", status, Hibernate.STRING)
.setParameter("type", type, Hibernate.STRING);
another way to get exactly the output mentioned in the question:
envtext= "printenv".execute().text
envtext.split('\n').each
{ envvar=it.split("=")
println envvar[0]+" is "+envvar[1]
}
This can easily be extended to build a map with a subset of env vars matching a criteria:
envdict=[:]
envtext= "printenv".execute().text
envtext.split('\n').each
{ envvar=it.split("=")
if (envvar[0].startsWith("GERRIT_"))
envdict.put(envvar[0],envvar[1])
}
envdict.each{println it.key+" is "+it.value}
enter code here IN DATAFRAME:
val p=spark.read.format("csv").options(Map("header"->"true","delimiter"->"^")).load("filename.csv")
The simplest modification (to the code in your question) is this:
Range("A" & Rows.Count).End(xlUp).Select
Selection.EntireRow.Delete
Which can be simplified to:
Range("A" & Rows.Count).End(xlUp).EntireRow.Delete
If checked:
$( "SELECTOR" ).attr( "checked" ) // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.
Get the checked val:
$( "SELECTOR:checked" ).val()
Get the checked val numbers:
$( "SELECTOR:checked" ).length
Check or uncheck checkbox
$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );
This can't be done with pure HTML.
However if you have access to PHP on the Apache server (you tagged the post "apache") it can be done easilly - se the PHP glob function. If not - you might try Server Side Include - it's an Apache thing, and I don't know much about it.

You can use the Web Services using an API_KEY issuing a request like this:
https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&key=API_KEY
An API_KEY can be obtained in the Google Developer Console with a quota of 2,500 free requests/day.
A request can return JSON or XML results that can be used to draw a path on a map.

That's not a good solution because you're relying on exceptions for control flow. In your solution it's normal to get exceptions, it's normal to have them in the log.
public String test() {
String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
List<String> certs = jdbc.queryForList(sql, String.class);
if (certs.isEmpty()) {
return null;
} else {
return certs.get(0);
}
}
You need to rearrange your curly brackets. Your first statement is complete, so R interprets it as such and produces syntax errors on the other lines. Your code should look like:
if (dsnt<0.05) {
wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else if (dst<0.05) {
wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else {
t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
}
To put it more simply, if you have:
if(condition == TRUE) x <- TRUE
else x <- FALSE
Then R reads the first line and because it is complete, runs that in its entirety. When it gets to the next line, it goes "Else? Else what?" because it is a completely new statement. To have R interpret the else as part of the preceding if statement, you must have curly brackets to tell R that you aren't yet finished:
if(condition == TRUE) {x <- TRUE
} else {x <- FALSE}
I know this is an older question, but I found this nifty library on nuget that seems to do just the trick for me:
How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?
You can undo changes to tracked files with:
git reset HEAD --hard
You can remove untracked files with:
git clean -f
You can remove untracked files and directories with:
git clean -fd
but you can't undo change to untracked files.
You can remove ignored and untracked files and directories
git clean -fdx
but you can't undo change to ignored files.
You can also set clean.requireForce
to false
:
git config --global --add clean.requireForce false
to avoid using -f
(--force
) when you use git clean
.
primitive way:
public string ToBinary(int n)
{
if (n < 2) return n.ToString();
var divisor = n / 2;
var remainder = n % 2;
return ToBinary(divisor) + remainder;
}
I find that the the approved answer, request.env['PATH_INFO']
, works for getting the base URL, but this does not always contain the full path if you have nested routes. You can use request.env['HTTP_REFERER']
to get the full path and then see if it matches a given route:
request.env['HTTP_REFERER'].match?(my_cool_path)
I wanted to add this answer because I used the primary answer from this question as my basis for exporting from a datatable to Excel using OpenXML but then transitioned to OpenXMLWriter when I found it to be much faster than the above method.
You can find the full details in my answer in the link below. My code is in VB.NET though, so you'll have to convert it.

You can do it in a few ways.All the ways are technically the same but using Lambda would simplify some of the code. Lets say we initialize a List first with String, call it persons.
List<String> persons = new ArrayList<String>(){{add("a"); add("b"); add("c");}};
Stream<String> stream = persons.stream();
Now you can use either of the following ways.
Using the Lambda Expresiion to create a new StringArray with defined size.
String[] stringArray = stream.toArray(size->new String[size]);
Using the method reference directly.
String[] stringArray = stream.toArray(String[]::new);
I had the same problem but I used sql server 2008 r2, you must check in options and verify the paths where sql going to save the files .mdf and .ldf you must select the path of your sql server installation. I solved my problem with this, I hope it helps you.

The problem in your initial definition of the class is that you've written:
class name(object, name):
This means that the class inherits the base class called "object", and the base class called "name". However, there is no base class called "name", so it fails. Instead, all you need to do is have the variable in the special init method, which will mean that the class takes it as a variable.
class name(object):
def __init__(self, name):
print name
If you wanted to use the variable in other methods that you define within the class, you can assign name to self.name, and use that in any other method in the class without needing to pass it to the method.
For example:
class name(object):
def __init__(self, name):
self.name = name
def PrintName(self):
print self.name
a = name('bob')
a.PrintName()
bob
A simple way to achieve what you want:
import cv2
s_img = cv2.imread("smaller_image.png")
l_img = cv2.imread("larger_image.jpg")
x_offset=y_offset=50
l_img[y_offset:y_offset+s_img.shape[0], x_offset:x_offset+s_img.shape[1]] = s_img
I suppose you want to take care of the alpha channel too. Here is a quick and dirty way of doing so:
s_img = cv2.imread("smaller_image.png", -1)
y1, y2 = y_offset, y_offset + s_img.shape[0]
x1, x2 = x_offset, x_offset + s_img.shape[1]
alpha_s = s_img[:, :, 3] / 255.0
alpha_l = 1.0 - alpha_s
for c in range(0, 3):
l_img[y1:y2, x1:x2, c] = (alpha_s * s_img[:, :, c] +
alpha_l * l_img[y1:y2, x1:x2, c])
I tried all the above things, and still ng as sticking around globally. So in powershell I ran Get-Command ng
, and then it became clear what my problem was. I was using yarn heavily in the past, and all the old angular cli packages were also installed globally in the yarn cache location. I deleted my yarn cache for good measure, but probably could have just updated the global angular cli via yarn. In any case, I hope this helps remind some of you that if you use yarn, then global commands like ng can also live in another path than where npm puts them.
Try this.
public function insert_data_function($your_data)
{
$this->db->insert("your_table",$your_data);
$last_id = $this->db->insert_id();
return $last_id;
}
In my experience, using System.gc() is effectively a platform-specific form of optimization (where "platform" is the combination of hardware architecture, OS, JVM version and possible more runtime parameters such as RAM available), because its behaviour, while roughly predictable on a specific platform, can (and will) vary considerably between platforms.
Yes, there are situations where System.gc() will improve (perceived) performance. On example is if delays are tolerable in some parts of your app, but not in others (the game example cited above, where you want GC to happen at the start of a level, not during the level).
However, whether it will help or hurt (or do nothing) is highly dependent on the platform (as defined above).
So I think it is valid as a last-resort platform-specific optimization (i.e. if other performance optimizations are not enough). But you should never call it just because you believe it might help(without specific benchmarks), because chances are it will not.
Visual Studio 2015 doesn't install C++ by default. You have to rerun the setup, select Modify and then check Programming Language -> C++
You may also consider the following solution:
let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
return html + "<li>" + item + "</li>";
}, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;
I'd do it this way:
[in the public header]
typedef unsigned long E;
void Foo(E e);
[in the internal header]
enum Econtent { FUNCTIONALITY_NORMAL, FUNCTIONALITY_RESTRICTED, FUNCTIONALITY_FOR_PROJECT_X,
FORCE_32BIT = 0xFFFFFFFF };
By adding FORCE_32BIT we ensure that Econtent compiles to a long, so it's interchangeable with E.
input type = number
When you want to provide a number input, you can use the HTML5 input type="number" attribute value.
<input type="number" name="n" />
Here is the keyboard that comes up on iPhone 4:
iPhone Screenshot of HTML5 input type number Android 2.2 uses this keyboard for type=number:

Try like this.
<div style="overflow-y: scroll; height:400px;">

The overload that you're using sets the enumeration of serialization formatters. You need to specify the content type explicitly like:
httpResponseMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
I am in the role of maintaining application created by offshore development team. Now I am having all kinds of issues in the application because original database schema did not contain PRIMARY KEYS on some tables. So please dont let other people suffer because of your poor design. It is always good idea to have primary keys on tables.

They're essentially the same... They both use swig for templating, they both use karma and mocha for tests, passport integration, nodemon, etc.
Why so similar? Mean.js is a fork of Mean.io and both initiatives were started by the same guy... Mean.io is now under the umbrella of the company Linnovate and looks like the guy (Amos Haviv) stopped his collaboration with this company and started Mean.js. You can read more about the reasons here.
Now... main (or little) differences you can see right now are:
SCAFFOLDING AND BOILERPLATE GENERATION
Mean.io uses a custom cli tool named 'mean'
Mean.js uses Yeoman Generators
MODULARITY
Mean.io uses a more self-contained node packages modularity with client and server files inside the modules.
Mean.js uses modules just in the front-end (for angular), and connects them with Express. Although they were working on vertical modules as well...
BUILD SYSTEM
Mean.io has recently moved to gulp
Mean.js uses grunt
DEPLOYMENT
Both have Dockerfiles in their respective repos, and Mean.io has one-click install on Google Compute Engine, while Mean.js can also be deployed with one-click install on Digital Ocean.
DOCUMENTATION
Mean.io has ok docs
Mean.js has AWESOME docs
COMMUNITY
Mean.io has a bigger community since it was the original boilerplate
Mean.js has less momentum but steady growth
On a personal level, I like more the philosophy and openness of MeanJS and more the traction and modules/packages approach of MeanIO. Both are nice, and you'll end probably modifying them, so you can't really go wrong picking one or the other. Just take them as starting point and as a learning exercise.
MEAN is a generic way (coined by Valeri Karpov) to describe a boilerplate/framework that takes "Mongo + Express + Angular + Node" as the base of the stack. You can find frameworks with this stack that use other denomination, some of them really good for RAD (Rapid Application Development) and building SPAs. Eg:
You also have Hackathon Starter. It doesn't have A of MEAN (it is 'MEN'), but it rocks..
Have fun!

As with all good examples, you've simplified what you're actually trying to do. This is good, but it is worth noting that python has a lot of flexibility when it comes to class versus instance variables. The same can be said of methods. For a good list of possibilities, I recommend reading Michael Fötsch' new-style classes introduction, especially sections 2 through 6.
One thing that takes a lot of work to remember when getting started is that python is not java. More than just a cliche. In java, an entire class is compiled, making the namespace resolution real simple: any variables declared outside a method (anywhere) are instance (or, if static, class) variables and are implicitly accessible within methods.
With python, the grand rule of thumb is that there are three namespaces that are searched, in order, for variables:
{begin pedagogy}
There are limited exceptions to this. The main one that occurs to me is that, when a class definition is being loaded, the class definition is its own implicit namespace. But this lasts only as long as the module is being loaded, and is entirely bypassed when within a method. Thus:
>>> class A(object):
foo = 'foo'
bar = foo
>>> A.foo
'foo'
>>> A.bar
'foo'
but:
>>> class B(object):
foo = 'foo'
def get_foo():
return foo
bar = get_foo()
Traceback (most recent call last):
File "<pyshell#11>", line 1, in <module>
class B(object):
File "<pyshell#11>", line 5, in B
bar = get_foo()
File "<pyshell#11>", line 4, in get_foo
return foo
NameError: global name 'foo' is not defined
{end pedagogy}
In the end, the thing to remember is that you do have access to any of the variables you want to access, but probably not implicitly. If your goals are simple and straightforward, then going for Foo.bar or self.bar will probably be sufficient. If your example is getting more complicated, or you want to do fancy things like inheritance (you can inherit static/class methods!), or the idea of referring to the name of your class within the class itself seems wrong to you, check out the intro I linked.
Use this Code for read all files in folder and sub-folders also

List<string> files = get.GetAllFiles(@"D:\Document");
foreach(string f in files)
{
Console.WriteLine(f);
}
Console.Read();
}
}
class getfiles
{
public List<string> GetAllFiles(string sDirt)
{
List<string> files = new List<string>();
try
{
foreach (string file in Directory.GetFiles(sDirt))
{
files.Add(file);
}
foreach (string fl in Directory.GetDirectories(sDirt))
{
files.AddRange(GetAllFiles(fl));
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
return files;
}
}
Add this somewhere towards the start of your main app file (e.g. app.js):
global.__basedir = __dirname;
This sets a global variable that will always be equivalent to your app's base dir. Use it just like any other variable:
const yourModule = require(__basedir + '/path/to/module.js');
Simple...
Sorry, but I'm pretty sure Peter's answer is wrong. Note that the y axis goes down the page (common in graphics). As such the deltaY calculation has to be reversed, or you get the wrong answer.
Consider:
System.out.println (Math.toDegrees(Math.atan2(1,1)));
System.out.println (Math.toDegrees(Math.atan2(-1,1)));
System.out.println (Math.toDegrees(Math.atan2(1,-1)));
System.out.println (Math.toDegrees(Math.atan2(-1,-1)));
gives
45.0
-45.0
135.0
-135.0
So if in the example above, P1 is (1,1) and P2 is (2,2) [because Y increases down the page], the code above will give 45.0 degrees for the example shown, which is wrong. Change the order of the deltaY calculation and it works properly.
Instead of this :
for(int a = 0, b = 1; a<cards.length-1; b=a+1; a++;){
It should be
for(int a = 0, b = 1; a<cards.length()-1; b=a+1, a++){

long a = 1111;
Long b = new Long(1113);
System.out.println(b.equals(a) ? "equal" : "different");
System.out.println((long) b == a ? "equal" : "different");
I agree with what @fge said, more over. Lets look at example. Consider you have a method:
class A {
public void foo(OtherClass other) {
SomeData data = new SomeData("Some inner data");
other.doSomething(data);
}
}
Now if you want to check the inner data you can use the captor:
// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);
// Run the foo method with the mock
new A().foo(other);
// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());
// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);
Just in case anyone else encounters the same problems.
Note, that relations are required to be camelcase. So in my case available_videos() should have been availableVideos().
You can easily find out investigating the Laravel source:
// Illuminate\Database\Eloquent\Model.php
...
/**
* Get an attribute from the model.
*
* @param string $key
* @return mixed
*/
public function getAttribute($key)
{
$inAttributes = array_key_exists($key, $this->attributes);
// If the key references an attribute, we can just go ahead and return the
// plain attribute value from the model. This allows every attribute to
// be dynamically accessed through the _get method without accessors.
if ($inAttributes || $this->hasGetMutator($key))
{
return $this->getAttributeValue($key);
}
// If the key already exists in the relationships array, it just means the
// relationship has already been loaded, so we'll just return it out of
// here because there is no need to query within the relations twice.
if (array_key_exists($key, $this->relations))
{
return $this->relations[$key];
}
// If the "attribute" exists as a method on the model, we will just assume
// it is a relationship and will load and return results from the query
// and hydrate the relationship's value on the "relationships" array.
$camelKey = camel_case($key);
if (method_exists($this, $camelKey))
{
return $this->getRelationshipFromMethod($key, $camelKey);
}
}
This also explains why my code worked, whenever I loaded the data using the load() method before.
Anyway, my example works perfectly okay now, and $model->availableVideos always returns a Collection.
DataTable dt = myDataRowCollection.CopyToDataTable<DataRow>();
We had the same problem and solved it by checking the error.log of our virtual host. We found the following message:
AH00670: Options FollowSymLinks and SymLinksIfOwnerMatch are both off, so the RewriteRule directive is also forbidden due to its similar ability to circumvent directory restrictions : /srv/www/htdocs/wp-intranet/
The solution was to set Options All
and AllowOverride All
in our virtual host config.

I wrote a small command-line based Python script based on pesterfesh that does exactly this:
Set setHasMenuOptions(true)
works if application has a theme with Actionbar
such as Theme.MaterialComponents.DayNight.DarkActionBar
or Activity has it's own Toolbar, otherwise onCreateOptionsMenu
in fragment does not get called.
If you want to use standalone Toolbar you either need to get activity and set your Toolbar as support action bar with
(requireActivity() as? MainActivity)?.setSupportActionBar(toolbar)
which lets your fragment onCreateOptionsMenu to be called.
Other alternative is, you can inflate your Toolbar's own menu with toolbar.inflateMenu(R.menu.YOUR_MENU)
and item listener with
toolbar.setOnMenuItemClickListener {
// do something
true
}
Simple jQuery solution - find the <a>

Simple way to initiate the message on startup:
bot.on('ready', () => {
bot.user.setStatus('available')
bot.user.setPresence({
game: {
name: 'with depression',
type: "STREAMING",
url: "https://www.twitch.tv/monstercat"
}
});
});
You can also just declare it elsewhere after startup, to change the message as needed:
bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}});
This is how I did it:
First define the column names you'll use, or leave it blank and pdo will assume you want to use all the columns on the table - in which case you'll need to inform the row values in the exact order they appear on the table.
$cols = 'name', 'middleName', 'eMail';
$table = 'people';
Now, suppose you have a two dimensional array already prepared. Iterate it, and construct a string with your row values, as such:
foreach ( $people as $person ) {
if(! $rowVals ) {
$rows = '(' . "'$name'" . ',' . "'$middleName'" . ',' . "'$eMail'" . ')';
} else { $rowVals = '(' . "'$name'" . ',' . "'$middleName'" . ',' . "'$eMail'" . ')';
}
Now, what you just did was check if $rows was already defined, and if not, create it and store row values and the necessary SQL syntax so it will be a valid statement. Note that strings should go inside double quotes and single quotes, so they will be promptly recognized as such.
All it's left to do is prepare the statement and execute, as such:
$stmt = $db->prepare ( "INSERT INTO $table $cols VALUES $rowVals" );
$stmt->execute ();
Tested with up to 2000 rows so far, and the execution time is dismal. Will run some more tests and will get back here in case I have something further to contribute.

In Laravel 4 & 5 (up to 5.7), you can use str_limit
, which limits the number of characters in a string.
While in Laravel 5.8 up, you can use the Str::limit
helper.
//For Laravel 4 to Laravel 5.5
{{ str_limit($string, $limit = 150, $end = '...') }}
//For Laravel 5.5 upwards
{{ \Illuminate\Support\Str::limit($string, 150, $end='...') }}

If the performance hit of the default constructor isn't an issue, the please, for the love of god, go with the more readable version.

OneToOneField: if second table is related with
table2_col1 = models.OneToOneField(table1,on_delete=models.CASCADE, related_name='table1_id')
table2 will contains only one record corresponding to table1's pk value, i.e table2_col1 will have unique value equal to pk of table
table2_col1 == models.ForeignKey(table1, on_delete=models.CASCADE, related_name='table1_id')
table2 may contains more than one record corresponding to table1's pk value.
