You could try killing one of the java.exe services running in your task manager - ps make sure you dont kill eclipse since that is listed as java.exe as well. If nothing else works, restarting your machine will fix it anyhow. It looks like youre not shutting down a socket from a previous test. Hope this helps.
So there are many ways but one which worked for me is as follows since I already had my requirements.txt file freeze.
So delete old virtual environment with following command
use
deactivate
cd ..
rm -r old_virtual_environment
to install virtualenv python package with pip
use pip install virtualenv
then check if it's installed correctly
use virtualenv --version
jump to your project directory
use cd project_directory
now create new virtual environment inside project directory using following
use virtualenv name_of_new_virtual_environment
now activate newly created virtual environment
use source name_of_new_virtual_environment/bin/activate
now install all project dependencies using following command
use pip install -r requirements.txt
The (un)safe way to do this - if you are ok with not using option explicit - is...
Not TypeName(myObj) = "Empty"
This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...
Dim myObj as Object
Not TypeName(myObj) = "Empty" '/ true, the object exists - TypeName is Object
'Dim myObj as Object
Not TypeName(myObj) = "Empty" '/ false, the object has not been declared
This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.
For JavaScript arrays, you use push()
.
var a = [];
a.push(12);
a.push(32);
For jQuery objects, there's add()
.
$('div.test').add('p.blue');
Note that while push()
modifies the original array in-place, add()
returns a new jQuery object, it does not modify the original one.
Change your constructor to pass true as the second argument.
TextWriter tsw = new StreamWriter(@"C:\Hello.txt", true);
you can try this
class select_choice():
return x, y
a, b = test()
Another summary:
You need to use both. ETags are a "server side" information. Expires are a "Client side" caching.
Use ETags except if you have a load-balanced server. They are safe and will let clients know they should get new versions of your server files every time you change something on your side.
Expires must be used with caution, as if you set a expiration date far in the future but want to change one of the files immediatelly (a JS file for instance), some users may not get the modified version until a long time!
If you want to access redis
from the host (127.0.0.1), you have to use the ports
command.
redis:

I am using microsoft's Android emulator with Android Studio. I have an AMD FX8350. The ARM one in android studio is terribly slow.
The only issue is that it requires Hyper-V which is not available on windows 10 Home.
Its a really quick emulator and it is free. The best emulator I have used.
You can use node.js http module to do that. You could check the documentation at Node.js HTTP.
You would need to pass the query string as well to the other HTTP Server. You should have that in ServerRequest.url.
Once you have those info, you could pass in the backend HTTP Server and port in the options that you will provide in the http.request()
@Annk you can make a variable in the __component.ts file
myImage : string = "http://example.com/path/image.png";
and inside the __.component.html file you can use one of those 3 methods :
1 .
<div> <img src="{{myImage}}"> </div>
2 .
<div> <img [src]="myImage"/> </div>
3 .
<div> <img bind-src="myImage"/> </div>
All the above methods will work fine if your content-type is "application/-www-form-urlencoded". But if your content-type is "application/json" then you will have to do the following:
$params = json_decode(file_get_contents('php://input'), true); print_r($params);
Reason : See #7 in https://www.toptal.com/php/10-most-common-mistakes-php-programmers-make
Check if element is visible in viewport using jquery:
First determine the top and bottom positions of the element. Then determine the position of the viewport's bottom (relative to the top of your page) by adding the scroll position to the viewport height.
If the bottom position of the viewport is greater than the element's top position AND the top position of the viewport is less than the element's bottom position, the element is in the viewport (at least partially). In simpler terms, when any part of the element is between the top and bottom bounds of your viewport, the element is visible on your screen.
Now you can write an if/else statement, where the if statement only runs when the above condition is met.
The code below executes what was explained above:
// this function runs every time you are scrolling
$(window).scroll(function() {
var top_of_element = $("#element").offset().top;
var bottom_of_element = $("#element").offset().top + $("#element").outerHeight();
var bottom_of_screen = $(window).scrollTop() + $(window).innerHeight();
var top_of_screen = $(window).scrollTop();
if ((bottom_of_screen > top_of_element) && (top_of_screen < bottom_of_element)){
// the element is visible, do something
} else {
// the element is not visible, do something else
}
});
This answer is a summary of what Chris Bier and Andy were discussing below. I hope it helps anyone else who comes across this question while doing research like I did. I also used an answer to the following question to formulate my answer: Show Div when scroll position.

//block all selects
jQuery(document).on("focusin", 'select.yourClass', function (event) {
var $selectDiabled = jQuery(this).attr('disabled', 'disabled');
setTimeout(function(){ $selectDiabled.removeAttr("disabled"); }, 30);
});

In CurrentGame
component you need to change initial state because you are trying use loop for participants
but this property is undefined
that's why you get error.,
getInitialState: function(){
return {
data: {
participants: []
}
};
},
also, as player
in .map
is Object
you should get properties from it
this.props.data.participants.map(function(player) {
return <li key={player.championId}>{player.summonerName}</li>
// -------------------^^^^^^^^^^^---------^^^^^^^^^^^^^^
})
Even though I'm 6 years late, but I think all the answers above didn't properly address the question @kalai is asking. The bash script below will process a text file in the following format:
URL | start_time | end_time | filename
for example
https://www.youtube.com/watch?v=iUDURCrvrMI|00:02:02|00:03:41|1
and loop through the file, downloads the file that youtube-dl
supports, calculating duration between start_time
and end_time
and passing it to ffmpeg
, since -t
is actually the duration, not the real end_time
Hit me up if you have any question.
for i in $(<video.txt);
do
URL=`echo $i | cut -d "|" -f 1`;
START=`echo $i | cut -d "|" -f 2`;
END=`echo $i | cut -d "|" -f 3`;
FILE=`echo $i | cut -d "|" -f 4`;
SEC1=`echo $START | sed 's/^/((/; s/:/)*60+/g' | bc`
SEC2=`echo $END | sed 's/^/((/; s/:/)*60+/g' | bc`
DIFFSEC=`expr ${SEC2} - ${SEC1}`
ffmpeg $(youtube-dl -g $URL | sed "s/.*/-ss $START -i &/") -t $DIFFSEC -c copy $FILE".mkv";
ffmpeg -i $FILE".mkv" -f mp3 -ab 192000 -vn $FILE".mp3";

There are two ways to access properties of objects:
var obj = {a: 'foo', b: 'bar'};
obj.a //foo
obj['b'] //bar
Or, if you need to dynamically do it:
var key = 'b';
obj[key] //bar
If you don't already have it as an object, you'll need to convert it.
For a more complex example, let's assume you have an array of objects that represent users:
var users = [{name: 'Corbin', age: 20, favoriteFoods: ['ice cream', 'pizza']},
{name: 'John', age: 25, favoriteFoods: ['ice cream', 'skittle']}];
To access the age property of the second user, you would use users[1].age
. To access the second "favoriteFood" of the first user, you'd use users[0].favoriteFoods[2]
.
Another example: obj[2].key[3]["some key"]
That would access the 3rd element of an array named 2. Then, it would access 'key' in that array, go to the third element of that, and then access the property name some key
.
As Amadan noted, it might be worth also discussing how to loop over different structures.
To loop over an array, you can use a simple for loop:
var arr = ['a', 'b', 'c'],
i;
for (i = 0; i < arr.length; ++i) {
console.log(arr[i]);
}
To loop over an object is a bit more complicated. In the case that you're absolutely positive that the object is a plain object, you can use a plain for (x in obj) { }
loop, but it's a lot safer to add in a hasOwnProperty check. This is necessary in situations where you cannot verify that the object does not have inherited properties. (It also future proofs the code a bit.)
var user = {name: 'Corbin', age: 20, location: 'USA'},
key;
for (key in user) {
if (user.hasOwnProperty(key)) {
console.log(key + " = " + user[key]);
}
}
(Note that I've assumed whatever JS implementation you're using has console.log
. If not, you could use alert
or some kind of DOM manipulation instead.)
My answer addresses the specific (and somewhat common) case where you don't really need to convert the entire xml to json, but what you need is to traverse/access specific parts of the xml, and you need it to be fast, and simple (using json/dict-like operations).
For this, it is important to note that parsing an xml to etree using lxml
is super fast. The slow part in most of the other answers is the second pass: traversing the etree structure (usually in python-land), converting it to json.
Which leads me to the approach I found best for this case: parsing the xml using lxml
, and then wrapping the etree nodes (lazily), providing them with a dict-like interface.
Here's the code:
from collections import Mapping
import lxml.etree
class ETreeDictWrapper(Mapping):
def __init__(self, elem, attr_prefix = '@', list_tags = ()):
self.elem = elem
self.attr_prefix = attr_prefix
self.list_tags = list_tags
def _wrap(self, e):
if isinstance(e, basestring):
return e
if len(e) == 0 and len(e.attrib) == 0:
return e.text
return type(self)(
e,
attr_prefix = self.attr_prefix,
list_tags = self.list_tags,
)
def __getitem__(self, key):
if key.startswith(self.attr_prefix):
return self.elem.attrib[key[len(self.attr_prefix):]]
else:
subelems = [ e for e in self.elem.iterchildren() if e.tag == key ]
if len(subelems) > 1 or key in self.list_tags:
return [ self._wrap(x) for x in subelems ]
elif len(subelems) == 1:
return self._wrap(subelems[0])
else:
raise KeyError(key)
def __iter__(self):
return iter(set( k.tag for k in self.elem) |
set( self.attr_prefix + k for k in self.elem.attrib ))
def __len__(self):
return len(self.elem) + len(self.elem.attrib)
# defining __contains__ is not necessary, but improves speed
def __contains__(self, key):
if key.startswith(self.attr_prefix):
return key[len(self.attr_prefix):] in self.elem.attrib
else:
return any( e.tag == key for e in self.elem.iterchildren() )
def xml_to_dictlike(xmlstr, attr_prefix = '@', list_tags = ()):
t = lxml.etree.fromstring(xmlstr)
return ETreeDictWrapper(
t,
attr_prefix = '@',
list_tags = set(list_tags),
)
This implementation is not complete, e.g., it doesn't cleanly support cases where an element has both text and attributes, or both text and children (only because I didn't need it when I wrote it...) It should be easy to improve it, though.
In my specific use case, where I needed to only process specific elements of the xml, this approach gave a suprising and striking speedup by a factor of 70 (!) compared to using @Martin Blech's xmltodict and then traversing the dict directly.
As a bonus, since our structure is already dict-like, we get another alternative implementation of xml2json
for free. We just need to pass our dict-like structure to json.dumps
. Something like:
def xml_to_json(xmlstr, **kwargs):
x = xml_to_dictlike(xmlstr, **kwargs)
return json.dumps(x)
If your xml includes attributes, you'd need to use some alphanumeric attr_prefix
(e.g. "ATTR_"), to ensure the keys are valid json keys.
I haven't benchmarked this part.
Android SDK build tools are used to debug, build, run and test an Android application.
Android Build Tools can be used to develop and work from command line or IDE (i.e Eclipse or Android Studio).
Also used to connect Android devices and root them.(fastboot, adb and more..)

I would suggest reading this url http://docs.angularjs.org/api/ngResource/service/$resource
and revaluate how you are calling your delete method of your resources.
ideally you would want to be calling the delete of the resource item itself and by not passing the id of the resource into a catch all delete method
however $http.delete accepts a config object that contains both url and data properties you could either craft the query string there or pass an object/string into the data
maybe something along these lines
$http.delete('/roles/'+roleid, {data: input});
Just find the remainder by dividing by 1, that is x%1. If the remainder is 0, it means that x is a whole number. Otherwise, you have to display the message "Must input numbers". This will work even in the case of strings, decimal numbers etc.
function checkInp()
{
var x = document.forms["myForm"]["age"].value;
if ((x%1) != 0)
{
alert("Must input numbers");
return false;
}
}
Thanks to https://stackoverflow.com/users/1652962/cimmanon that gave me the answer.
The solution is setting a height to the vertical scrollable element. For example:
#container article {
flex: 1 1 auto;
overflow-y: auto;
height: 0px;
}
The element will have height because flexbox recalculates it unless you want a min-height so you can use height: 100px;
that it is exactly the same as: min-height: 100px;
#container article {
flex: 1 1 auto;
overflow-y: auto;
height: 100px; /* == min-height: 100px*/
}
So the best solution if you want a min-height
in the vertical scroll:
#container article {
flex: 1 1 auto;
overflow-y: auto;
min-height: 100px;
}
If you just want full vertical scroll in case there is no enough space to see the article:
#container article {
flex: 1 1 auto;
overflow-y: auto;
min-height: 0px;
}

On newer versions of Windows (Windows 10 and Windows Server 2016) the tasks you create are located in C:\Windows\Tasks
. They will have the extension .job
For example if you create the task "DoWork" it will create the task in
C:\Windows\Tasks\DoWork.job
you need to prevent the default behavior of your form when submitting
by adding this:
$("#postcontent").on('submit' , function(e) {
e.preventDefault();
//then the rest of your code
}
If you care about the speed use ujson (UltraJSON), which has the same API as json:
import ujson
ujson.dumps([{"key": "value"}, 81, True])
# '[{"key":"value"},81,true]'
ujson.loads("""[{"key": "value"}, 81, true]""")
# [{u'key': u'value'}, 81, True]
$key = array_search($needle, $array);
if ($key !== false) {
unset($array[$key]);
}

The Bundle
is a container for all the information you want to save. You use the put* functions to insert data into it. Here's a short list (there are more) of put functions you can use to store data in the Bundle
.
putString
putBoolean
putByte
putChar
putFloat
putLong
putShort
putParcelable (used for objects but they must implement Parcelable)
In your onCreate
function, this Bundle
is handed back to the program. The best way to check if the application is being reloaded, or started for the first time is:
if (savedInstanceState != null) {
// Then the application is being reloaded
}
To get the data back out, use the get* functions just like the put* functions. The data is stored as a name-value pair. This is like a hashmap. You provide a key and the value, then when you want the value back, you give the key and the function gets the value. Here's a short example.
@Override
public void onSaveInstanceState(Bundle outState) {
outState.putString("message", "This is my message to be reloaded");
super.onSaveInstanceState(outState);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
String message = savedInstanceState.getString("message");
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
}
Your saved message will be toasted to the screen. Hope this helps.
An unsigned 1 byte number can contain the range [0-255] inclusive. So when you see 255, it is mostly because programmers think in base 10
(get the joke?) :)
Actually, for a while, 255 was the largest size you could give a VARCHAR in MySQL, and there are advantages to using VARCHAR over TEXT with indexing and other issues.
You can also upload using HTML5. You can use this AJAX uploader.
The JS code is basically:
$scope.doPhotoUpload = function () {
// ..
var myUploader = new uploader(document.getElementById('file_upload_element_id'), options);
myUploader.send();
// ..
}
Which reads from an HTML input element
<input id="file_upload_element_id" type="file" onchange="angular.element(this).scope().doPhotoUpload()">
You can parse the text as a string, which creates an Element, and create an ElementTree using that Element.
import xml.etree.ElementTree as ET
tree = ET.ElementTree(ET.fromstring(xmlstring))
I just came across this issue and the documentation, while complete, is not very straightforward on the difference in usage between the parse()
and fromstring()
methods.

var image = e.target.result;
$("#imgthumbnail").attr('src', image);
});
});

If you are already using Newtonsoft.Json try this:
// Alternative using WebApi.Client 5.2.7
////var response = await Client.PutAsJsonAsync(
//// "api/AgentCollection", user
//// requestListDto)
var response = await Client.PostAsync("api/AgentCollection", new StringContent(
JsonConvert.SerializeObject(user), Encoding.UTF8, "application/json"));
Performance are better than JavaScriptSerializer. Take a look here https://www.newtonsoft.com/json/help/html/Introduction.htm
If you want to find the rows that are duplicated you can use find_duplicates
from hablar
:
library(dplyr)
library(hablar)
df <- tibble(a = c(1, 2, 2, 4),
b = c(5, 2, 2, 8))
df %>% find_duplicates()
In my case I added the missing import, which was the ReactiveFormsModule
.
You can find elements by available methods and check response array length if the length of an array equal the 0 element not exist.
element_exist = False if len(driver.find_elements_by_css_selector('div.eiCW-')) > 0 else True
your string is NOT a valid json to start with.
a valid json will be,
{
"area": [
{
"area": "kothrud"
},
{
"area": "katraj"
}
]
}
if you do a json_decode
, it will yield,
stdClass Object
(
[area] => Array
(
[0] => stdClass Object
(
[area] => kothrud
)
[1] => stdClass Object
(
[area] => katraj
)
)
)
Update: to use
$string = '
{
"area": [
{
"area": "kothrud"
},
{
"area": "katraj"
}
]
}
';
$area = json_decode($string, true);
foreach($area['area'] as $i => $v)
{
echo $v['area'].'<br/>';
}
Output:
kothrud
katraj
Update #2:
for that true

You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question.

print $ids
should be a fairly hard statement to mess up, but it is possible. Possible reasons:
$ids
is undefined. Gives the warning undefined value in print
$ids
is out of scope. With use
strict
, gives fatal warning Global
variable $ids needs explicit package
name
, and otherwise the undefined
warning from above.print $ids $nIds
,
in which case perl thinks that $ids
is supposed to be a filehandle, and
you get an error such as print to
unopened filehandle
.Explanations
1: Should not happen. It might happen if you do something like this (assuming you are not using strict
):
my $var;
while (<>) {
$Var .= $_;
}
print $var;
Gives the warning for undefined value, because $Var
and $var
are two different variables.
2: Might happen, if you do something like this:
if ($something) {
my $var = "something happened!";
}
print $var;
my
declares the variable inside the current block. Outside the block, it is out of scope.
3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings
.
4: Also a common mistake. There are a number of ways to correctly print two variables in the same print
statement:
print "$var1 $var2"; # concatenation inside a double quoted string
print $var1 . $var2; # concatenation
print $var1, $var2; # supplying print with a list of args
Lastly, some perl magic tips for you:
use strict;
use warnings;
# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;
# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;
my $ids = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";
Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.
Variations:
print "@file"
is equivalent to
$ids = join(' ',@file); print $ids;
$#file
will return the last index
in @file
. Since arrays usually start at 0,
$#file + 1
is equivalent to scalar @file
. You can also do:
my $ids;
do {
local $/;
$ids = <$fh>;
}
By temporarily "turning off" $/
, the input record separator, i.e. newline, you will make <$fh>
return the entire file. What <$fh>
really does is read until it finds $/
, then return that string. Note that this will preserve the newlines in $ids
.
Line-by-line solution:
open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
chomp;
$ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.
I had the same issue, with Build Tools revision 24.0.0-rc4. The fix was to install the package using the command line.
~/Android/Sdk| ls -1 build-tools/
23.0.3
24.0.0-rc4
~/Android/Sdk| ./tools/android list sdk -a | grep "SDK Build-tools"
4- Android SDK Build-tools, revision 24 rc4
5- Android SDK Build-tools, revision 23.0.3
6- Android SDK Build-tools, revision 23.0.2
7- Android SDK Build-tools, revision 23.0.1
8- Android SDK Build-tools, revision 23 (Obsolete)
...
~/Android/Sdk| ./tools/android update sdk -a -u -t 4
...
~/Android/Sdk| ls -1 build-tools/
23.0.3
24.0.0-preview
24.0.0-rc4
(note that 4
in the android update sdk
command above refers to the preceding list's number for the desired version, found at the beginning of the line).
The directory build-tools/24.0.0-rc4/
had been created when I installed the package from Android Studio's SDK Manager. The above method created build-tools/24.0.0-preview/
.
My app-level build.gradle
script uses the -rc4
version, as specified in the setup guide:
android {
compileSdkVersion 'android-N'
buildToolsVersion '24.0.0-rc4'
}
I do not understand the correlation between -rc4
and -preview
or why specifying 24.0.0-rc4
picks up the -preview
package, but it did fix the issue for me.
Your #container should be outside of the #header-wrap, then specify a fixed height for #header-wrap, after, specify margin-top for #container equal to the #header-wrap's height. Something like this:
#header-wrap {
position: fixed;
height: 200px;
top: 0;
width: 100%;
z-index: 100;
}
#container{
margin-top: 200px;
}

As far as I can tell, both syntaxes are equivalent. The first is SQL standard, the second is MySQL's extension.
So they should be exactly equivalent performance wise.
http://dev.mysql.com/doc/refman/5.6/en/insert.html says:
INSERT inserts new rows into an existing table. The INSERT ... VALUES and INSERT ... SET forms of the statement insert rows based on explicitly specified values. The INSERT ... SELECT form inserts rows selected from another table or tables.
My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v
if you just want that...
This is with HPUX, if the content of the files has space between words, use this:

Here are the primary differences between using System.out
/.err
/.in
and System.console()
:
System.console()
returns null if your application is not run in a terminal (though you can handle this in your application)System.console()
provides methods for reading password without echoing charactersSystem.out
and System.err
use the default platform encoding, while the Console
class output methods use the console encodingThis latter behaviour may not be immediately obvious, but code like this can demonstrate the difference:
public class ConsoleDemo {
public static void main(String[] args) {
String[] data = { "\u250C\u2500\u2500\u2500\u2500\u2500\u2510",
"\u2502Hello\u2502",
"\u2514\u2500\u2500\u2500\u2500\u2500\u2518" };
for (String s : data) {
System.out.println(s);
}
for (String s : data) {
System.console().writer().println(s);
}
}
}
On my Windows XP which has a system encoding of windows-1252 and a default console encoding of IBM850, this code will write:
???????
?Hello?
???????
+-----+
¦Hello¦
+-----+
Note that this behaviour depends on the console encoding being set to a different encoding to the system encoding. This is the default behaviour on Windows for a bunch of historical reasons.
This is really similar to another question. How should I load files into my Java application?
How should I load my files into my Java Application?
You do not want to load your files in by:
C:\your\project\file.txt
this is bad!
You should use getResourceAsStream.
InputStream inputStream = YourClass.class.getResourceAsStream(“file.txt”);
And also you should use File.separator; which is the system-dependent name-separator character, represented as a string for convenience.
In a talk about core containers internals in Python at PyCon 2012, Raymond Hettinger is suggesting to use [None] * n
to pre-allocate the length you want.
Slides available as PPT or via Google
The whole slide deck is quite interesting. The presentation is available on YouTube, but it doesn't add much to the slides.
In Visual Studio Code at least, you can force a Javadoc comment to respect line-breaks by wrapping it in triple-backticks, as seen below:
/** ```markdown
* This content is rendered in (partial) markdown.
*
* For example, *italic* and **bold** text works, but [links](https://www.google.com) do not.
* Bonus: it keeps single line-breaks, as seen between this line and the previous.
``` */
You can try this
import sys
reload(sys)
sys.setdefaultencoding("utf-8")
Or
You can also try following
Add following line at top of your .py file.
# -*- coding: utf-8 -*-
With Postgres, you may use
select * from users where active
or
select * from users where active = 't'
If you want to use integer value, you have to consider it as a string. You can't use integer value.
select * from users where active = 1 -- Does not work
select * from users where active = '1' -- Works
Agree with Heinzi's answer. For first second option, here's a query that generates a comma-separated list of columns in a table:
select name + ', ' as [text()]
from sys.columns
where object_id = object_id('YourTable')
for xml path('')
For big tables, this can save a lot of typing work :)
I prefer using the onclick method rather than the href for javascript hyperlinks. And always use alerts to determine what value do you have.
<a href='#' onclick='jsFunction();alert('it works!');'>Link</a>
It could be also used on input tags eg.
<input type='button' value='Submit' onclick='jsFunction();alert('it works!');'>
Here is one using newer javascript functions fill, map, reduce and constructor (and fat arrow syntax):
Math.factorial = n => n === 0 ? 1 : Array(n).fill(null).map((e,i)=>i+1).reduce((p,c)=>p*c)
Edit: updated to handle n === 0
This also happened to me when a PercentageRelativeLayout https://developer.android.com/reference/android/support/percent/PercentRelativeLayout.html was used and the build was targeting Android 0 = 26. PercentageRelativeLayout layout is obsolete starting from Android O and obviously sometime was changed in the resource generation. Replacing the layout with a ConstraintLayout or just a RelativeLayout solved it.
In the parent process, fork()'s return value is the process ID of the child process. Stuff that value away somewhere for when you need to terminate the child process. fork() returns zero(0) in the child process.
When you need to terminate the child process, use the kill(2) function with the process ID returned by fork(), and the signal you wish to deliver (e.g. SIGTERM).
Remember to call wait() on the child process to prevent any lingering zombies.
The easiest way is probably to use two parameters: One for hosts (can be an array), and one for vlan.
param([String[]] $Hosts, [String] $VLAN)
Instead of
foreach ($i in $args)
you can use
foreach ($hostName in $Hosts)
If there is only one host, the foreach loop will iterate only once. To pass multiple hosts to the script, pass it as an array:
myScript.ps1 -Hosts host1,host2,host3 -VLAN 2
...or something similar.
If you want to access your page's global variables, you can do so:
@{
ViewData["Title"] = "Home Page";
var LoadingButtons = Model.ToDictionary(person => person, person => false);
string GetLoadingState (string person) => LoadingButtons[person] ? "is-loading" : string.Empty;
}
Had a similar problem, fixed it by calling python3
instead of python
, my modules were in Python3.5.
New Version queries have a different format
To reach a lat long by url use (e.g.)
Use os.path.getsize(path)
which will
Return the size, in bytes, of path. Raise
OSError
if the file does not exist or is inaccessible.
import os
os.path.getsize('C:\\Python27\\Lib\\genericpath.py')
Or use os.stat(path).st_size
import os
os.stat('C:\\Python27\\Lib\\genericpath.py').st_size
Or use Path(path).stat().st_size
(Python 3.4+)
from pathlib import Path
Path('C:\\Python27\\Lib\\genericpath.py').stat().st_size
In your example you are comparing the string objects, not their content.
Your comparison should be :
if (s.equals("/quit"))
Or if s
string nullity doesn't mind / or you really don't like NPEs:
if ("/quit".equals(s))
What you have should work. If, however, the spaces provided are defaulting to... something else? You can use the whitespace regex:
str = "Hello I'm your String";
String[] splited = str.split("\\s+");
This will cause any number of consecutive spaces to split your string into tokens.
As a side note, I'm not sure "splited" is a word :) I believe the state of being the victim of a split is also "split". It's one of those tricky grammar things :-) Not trying to be picky, just figured I'd pass it on!
Load Testing: Large amount of users Stress Testing: Too many users, too much data, too little time and too little room
Because the join()
method is in the string class, instead of the list class?
I agree it looks funny.
See http://www.faqs.org/docs/diveintopython/odbchelper_join.html:
Historical note. When I first learned Python, I expected join to be a method of a list, which would take the delimiter as an argument. Lots of people feel the same way, and there’s a story behind the join method. Prior to Python 1.6, strings didn’t have all these useful methods. There was a separate string module which contained all the string functions; each function took a string as its first argument. The functions were deemed important enough to put onto the strings themselves, which made sense for functions like lower, upper, and split. But many hard-core Python programmers objected to the new join method, arguing that it should be a method of the list instead, or that it shouldn’t move at all but simply stay a part of the old string module (which still has lots of useful stuff in it). I use the new join method exclusively, but you will see code written either way, and if it really bothers you, you can use the old string.join function instead.

The code that you looked at is not ideal. You should either:
Catch the exception and handle it;
in which case the throws
is
unnecesary.
Remove the try/catch
; in which case
the Exception will be handled by a
calling method.
Catch the exception, possibly perform some action and then rethrow the exception (not just the message)

Specify complete path and grant proper permission to scriptfile. I tried following script file to run through cron:

It worked for me.
I used docker-entrypoint-initdb.d approach (Thanks to @Kuhess) But in my case I want to create my DB based on some parameters I defined in .env file so I did these
1) First I define .env file something like this in my docker root project directory
MYSQL_DATABASE=my_db_name
MYSQL_USER=user_test
MYSQL_PASSWORD=test
MYSQL_ROOT_PASSWORD=test
MYSQL_PORT=3306
2) Then I define my docker-compose.yml file. So I used the args directive to define my environment variables and I set them from .env file
version: '2'
services:
### MySQL Container
mysql:
build:
context: ./mysql
args:
- MYSQL_DATABASE=${MYSQL_DATABASE}
- MYSQL_USER=${MYSQL_USER}
- MYSQL_PASSWORD=${MYSQL_PASSWORD}
- MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
ports:
- "${MYSQL_PORT}:3306"
3) Then I define a mysql folder that includes a Dockerfile. So the Dockerfile is this
FROM mysql:5.7
RUN chown -R mysql:root /var/lib/mysql/
ARG MYSQL_DATABASE
ARG MYSQL_USER
ARG MYSQL_PASSWORD
ARG MYSQL_ROOT_PASSWORD
ENV MYSQL_DATABASE=$MYSQL_DATABASE
ENV MYSQL_USER=$MYSQL_USER
ENV MYSQL_PASSWORD=$MYSQL_PASSWORD
ENV MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD
ADD data.sql /etc/mysql/data.sql
RUN sed -i 's/MYSQL_DATABASE/'$MYSQL_DATABASE'/g' /etc/mysql/data.sql
RUN cp /etc/mysql/data.sql /docker-entrypoint-initdb.d
EXPOSE 3306
4) Now I use mysqldump to dump my db and put the data.sql inside mysql folder
mysqldump -h <server name> -u<user> -p <db name> > data.sql
The file is just a normal sql dump file but I add 2 lines at the beginning so the file would look like this
--
-- Create a database using `MYSQL_DATABASE` placeholder
--
CREATE DATABASE IF NOT EXISTS `MYSQL_DATABASE`;
USE `MYSQL_DATABASE`;
-- Rest of queries
DROP TABLE IF EXISTS `x`;
CREATE TABLE `x` (..)
LOCK TABLES `x` WRITE;
INSERT INTO `x` VALUES ...;
...
...
...
So what happening is that I used "RUN sed -i 's/MYSQL_DATABASE/'$MYSQL_DATABASE'/g' /etc/mysql/data.sql" command to replace the MYSQL_DATABASE
placeholder with the name of my DB that I have set it in .env file.
|- docker-compose.yml
|- .env
|- mysql
|- Dockerfile
|- data.sql
Now you are ready to build and run your container
This will do the trick :-
new Date().valueOf()
Similar to the accepted answer, the following code block might come in handy if you also want to make sure to create any (non-existent) folders in the path to the destination.
from os import path, makedirs
from shutil import copyfile
makedirs(path.dirname(path.abspath(destination_path)), exist_ok=True)
copyfile(source_path, destination_path)
As the accepted answers notes, these lines will overwrite any file which exists at the destination path, so sometimes it might be useful to also add: if not path.exists(destination_path):
before this code block.
I think you need str.contains
, if you need rows where values of column date
contains string 07311954
:
print df[df['date'].astype(str).str.contains('07311954')]
Or if type
of date
column is string
:
print df[df['date'].str.contains('07311954')]
If you want check last 4 digits for string
1954
in column date
:
print df[df['date'].astype(str).str[-4:].str.contains('1954')]
Sample:
print df['date']
0 8152007
1 9262007
2 7311954
3 2252011
4 2012011
5 2012011
6 2222011
7 2282011
Name: date, dtype: int64
print df['date'].astype(str).str[-4:].str.contains('1954')
0 False
1 False
2 True
3 False
4 False
5 False
6 False
7 False
Name: date, dtype: bool
print df[df['date'].astype(str).str[-4:].str.contains('1954')]

You can setup SSH key authorization like described here - https://confluence.atlassian.com/bitbucket/add-an-ssh-key-to-an-account-302811853.html.
For the Record:
Note that in PHP the switch statement is considered a looping structure for the purposes of continue.
Actually the best answer is
SELECT CONVERT(VARCHAR(1000), varbinary_value, 1);
using "2
" cuts off the "0x
" at the start of the varbinary
.
One advantage is that you are compiling access into the application, so it cannot accidentally be changed by someone modifying the Web.config.
This may not be an advantage to you, and might be a disadvantage. But for some kinds of access, it may be preferrable.
Plus, I find that authorization information in the Web.config pollutes it, and makes it harder to find things. So in some ways its preference, in others there is no other way to do it.
You can join
the table on itself to get the PK:
Select cpe1.PK, cpe2.MaxDate, cpe1.fmgcms_cpeclaimid
from Filteredfmgcms_claimpaymentestimate cpe1
INNER JOIN
(
select MAX(createdon) As MaxDate, fmgcms_cpeclaimid
from Filteredfmgcms_claimpaymentestimate
group by fmgcms_cpeclaimid
) cpe2
on cpe1.fmgcms_cpeclaimid = cpe2.fmgcms_cpeclaimid
and cpe1.createdon = cpe2.MaxDate
where cpe1.createdon < 'reportstartdate'
I got this error when I tried to write to a database on an Android system.
Apparently sqlite3 not only needs write permissions to the database file and the containing directory (as @austin-hyde already said in his answer) but also the environment variable TMPDIR
has to point to a (possibly writable) directory.
On my Android system I set it to TMPDIR="/data/local/tmp"
and now my script runs as expected :)
Edit:
If you can't set environment variables you can use one of the other methods listed here: https://www.sqlite.org/tempfiles.html#temporary_file_storage_locations
like PRAGMA temp_store_directory = 'directory-name';

Based on the syntax I'm assuming that it is some language which is descendant of C. As per what I have seen, length
is used for simple collection items like arrays and in most cases it is a property.
size()
is a function and is used for dynamic collection objects. However for all the purposes of using, you wont find any differences in outcome using either of them. In most implementations, size simply returns length property.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;
That method was added in Servlet 2.5.
So this problem can have at least 3 causes:
web.xml
is not declared conform Servlet 2.5 or newer.To solve it,
web.xml
complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.servlet-api.jar
or j2ee.jar
in /WEB-INF/lib
or even worse, the JRE/lib
or JRE/lib/ext
. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.You can use the username variable: %USERNAME%
Yes, you can.
From cplusplus.com:
Because these functions are operator overloading functions, the usual way in which they are called is:
strm >> variable;
Where
strm
is the identifier of a istream object andvariable
is an object of any type supported as right parameter. It is also possible to call a succession of extraction operations as:strm >> variable1 >> variable2 >> variable3; //...
which is the same as performing successive extractions from the same object
strm
.
Just replace strm
with cin
.

Well if you want fully transparent than you can use
border: 5px solid transparent;
If you mean opaque/transparent, than you can use
border: 5px solid rgba(255, 255, 255, .5);
Here, a
means alpha, which you can scale, 0-1.
Also some might suggest you to use opacity
which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba
seems better than using opacity
.
For older browsers, always declare the background color using #

There is an alternative way of just killing the daemon process by calling
kill -TERM PID
where PID
is the value stored in the file mysqld.pid

An oblique answer to the question is to write all the code as classes, apart from the index.php files, which are then the only points of entry. PHP files that contain classes will not cause anything to happen, even if they are invoked directly through Apache.
A direct answer is to include the following in .htaccess:
<FilesMatch "\.php$">
Order Allow,Deny
Deny from all
</FilesMatch>
<FilesMatch "index[0-9]?\.php$">
Order Allow,Deny
Allow from all
</FilesMatch>
This will allow any file like index.php, index2.php etc to be accessed, but will refuse access of any kind to other .php files. It will not affect other file types.
==========Advise==========
@martin clayton Answer is correct, But this is an advise only.
Please avoid the use of ambiguous variable in the stored procedure.
Example :
SELECT Id, dateCreated
INTO id, datecreated
FROM products
WHERE pName = iName
The above example will cause an error (null value error)
Example give below is correct. I hope this make sense.
Example :
SELECT Id, dateCreated
INTO val_id, val_datecreated
FROM products
WHERE pName = iName
You can also make them unambiguous by referencing the table, like:
[ Credit : maganap ]
SELECT p.Id, p.dateCreated INTO id, datecreated FROM products p
WHERE pName = iName
If the usage pattern justifies it, why not? While your team doesn't recognize the operator right away, with time they could. Humans learn new words all the time. Why not in programming?
The only caution I might state is that "^" doesn't have the short circuit semantics of your second boolean check. If you really need the short circuit semantics, then a static util method works too.
public static boolean xor(boolean a, boolean b) {
return (a && !b) || (b && !a);
}

If you're creating 2 executable JAR files, each will have it's own manifest file, and each manifest file will specify the class that contains the main()

In each JAR file, the manifest will be a file with the following path / name inside the JAR - META-INF/MANIFEST.MF
There are ways to specify alternatively named files as a JAR's manifest using the JAR command-line parameters.
The specific class you want to use is specified using Main-Class: package.classname inside the META-INF/MANIFEST.MF file.
As for how to do this in Netbeans - not sure off the top of my head - I usually use IntelliJ and / or Eclipse and usually build the JAR through ANT or Maven anyway.
JMX now uses port 7199 instead of port 8080 (as of Cassandra 0.8.xx).
This is configurable in your cassandra-env.sh file, but the default is 7199.
You can use this selector to undermouse object and then manipulate it as a jQuery object:
$(':hover').last();
webDriver.findElement(By.xpath("//a[@href='/docs/configuration']")).click();
The above line works fine. Please remove the space after href.
Is that element is visible in the page, if the element is not visible please scroll down the page then perform click action.
It is possible to connect to the database without specifying a password. Once you've done that you can then reset the passwords. I'm assuming that you've installed the database on your machine; if not you'll first need to connect to the machine the database is running on.
Ensure your user account is a member of the dba
group. How you do this depends on what OS you are running.
Enter sqlplus / as sysdba
in a Command Prompt/shell/Terminal window as appropriate. This should log you in to the database as SYS.
Once you're logged in, you can then enter
alter user SYS identified by "newpassword";
to reset the SYS password, and similarly for SYSTEM.
(Note: I haven't tried any of this on Oracle 12c; I'm assuming they haven't changed things since Oracle 11g.)
For specific month and year use date() as natural language as following
$first_date = date('d-m-Y',strtotime('first day of april 2010'));
$last_date = date('d-m-Y',strtotime('last day of april 2010'));
// Isn't it simple way?
but for Current month
$first_date = date('d-m-Y',strtotime('first day of this month'));
$last_date = date('d-m-Y',strtotime('last day of this month'));
An awk
code based on RS
.
awk '1' RS=',\n' file
or:
awk 'BEGIN{RS=",\n"}1' file
This last example will be valid for any char before newline:
awk '1' RS='.\n' file
Note: dot .
matches any character except line breaks.
Explanation
awk
allows us to use different record (line) regex
separators, we just need to include the comma before the line break (or dot
for any char) in the one used for the input
, the RS
.
Note: what that 1
means?
Short answer, It's just a shortcut to avoid using the print
statement.
In awk
when a condition gets matched the default action is to print the input line, example:
$ echo "test" |awk '1'
test
That's because 1
will be always true, so this expression is equivalent to:
$ echo "test"|awk '1==1'
test
$ echo "test"|awk '{if (1==1){print}}'
test

In addition to Shayne3000's answer you can also use a color resource (not only an int color). Kotlin version:
var indicatorViewDrawable = itemHolder.indicatorView.background
indicatorViewDrawable = DrawableCompat.wrap(indicatorViewDrawable)
val color = ResourcesCompat.getColor(context.resources, R.color.AppGreenColor, null) // get your color from resources
DrawableCompat.setTint(indicatorViewDrawable, color)
itemHolder.indicatorView.background = indicatorViewDrawable
Create an extension method?
Console.WriteLine(value.ToGBString());
// ...
public static class DoubleExtensions
{
public static string ToGBString(this double value)
{
return value.ToString(CultureInfo.GetCultureInfo("en-GB"));
}
}
I experienced this exact same issue. For me, the OPTIONS request would go through, but the POST request would say "aborted." This led me to believe that the browser was never making the POST request at all. Chrome said something like "Caution provisional headers are shown" in the request headers but no response headers were shown. In the end I turned to debugging on Firefox which led me to find out my server was responding with an error and no CORS headers were present on the response. Chrome was actually receiving the response, but not allowing the response to be shown in the network view.
try this:
static String getKeyFromValue(LinkedHashMap<String, String> map,String value) {
for (int x=0;x<map.size();x++){
if( String.valueOf( (new ArrayList<String>(map.values())).get(x) ).equals(value))
return String.valueOf((new ArrayList<String>(map.keySet())).get(x));
}
return null;
}
I've tried all the above solutions, but none of them worked for me. The following code helped me, when trying to return to MainActivity in a way that onCreate gets called:
Intent.FLAG_ACTIVITY_CLEAR_TOP is the key.
@Override
public void onBackPressed() {
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
This will do the trick
.gallery-item
{
opacity:1;
}

-o-transition: opacity .2s ease-out;
}
To get this running in Eclipse, as well as in a Maven build, you should add the addDefaultImplementationEntries
and addDefaultSpecificationEntries
pom entries as described in other replies, then use the following code:
public synchronized static final String getVersion() {
// Try to get version number from pom.xml (available in Eclipse)
try {
String className = getClass().getName();
String classfileName = "/" + className.replace('.', '/') + ".class";
URL classfileResource = getClass().getResource(classfileName);
if (classfileResource != null) {
Path absolutePackagePath = Paths.get(classfileResource.toURI())
.getParent();
int packagePathSegments = className.length()
- className.replace(".", "").length();
// Remove package segments from path, plus two more levels
// for "target/classes", which is the standard location for
// classes in Eclipse.
Path path = absolutePackagePath;
for (int i = 0, segmentsToRemove = packagePathSegments + 2;
i < segmentsToRemove; i++) {
path = path.getParent();
}
Path pom = path.resolve("pom.xml");
try (InputStream is = Files.newInputStream(pom)) {
Document doc = DocumentBuilderFactory.newInstance()
.newDocumentBuilder().parse(is);
doc.getDocumentElement().normalize();
String version = (String) XPathFactory.newInstance()
.newXPath().compile("/project/version")
.evaluate(doc, XPathConstants.STRING);
if (version != null) {
version = version.trim();
if (!version.isEmpty()) {
return version;
}
}
}
}
} catch (Exception e) {
// Ignore
}
// Try to get version number from maven properties in jar's META-INF
try (InputStream is = getClass()
.getResourceAsStream("/META-INF/maven/" + MAVEN_PACKAGE + "/"
+ MAVEN_ARTIFACT + "/pom.properties")) {
if (is != null) {
Properties p = new Properties();
p.load(is);
String version = p.getProperty("version", "").trim();
if (!version.isEmpty()) {
return version;
}
}
} catch (Exception e) {
// Ignore
}
// Fallback to using Java API to get version from MANIFEST.MF
String version = null;
Package pkg = getClass().getPackage();
if (pkg != null) {
version = pkg.getImplementationVersion();
if (version == null) {
version = pkg.getSpecificationVersion();
}
}
version = version == null ? "" : version.trim();
return version.isEmpty() ? "unknown" : version;
}
If your Java build puts target classes somewhere other than "target/classes", then you may need to adjust the value of segmentsToRemove.

I'm able to get the Class of the generic type this way:
class MyList<T> {
Class<T> clazz = (Class<T>) DAOUtil.getTypeArguments(MyList.class, this.getClass()).get(0);

You need two functions from this file: http://code.google.com/p/hibernate-generic-dao/source/browse/trunk/dao/src/main/java/com/googlecode/genericdao/dao/DAOUtil.java

OK, let's go a bit more comprehensive and start with what's Map for those who don't know this feature in JavaScript... MDN says:
The Map object holds key-value pairs and remembers the original insertion order of the keys.
Any value (both objects and primitive values) may be used as either a key or a value.
As you mentioned, you can easily create an instance of Map using new keyword... In your case:
let myMap = new Map().set('a', 1).set('b', 2);
So let's see...
The way you mentioned is an OK way to do it, but yes, there are more concise ways to do that...
Map has many methods which you can use, like set()
which you already used to assign the key values...
One of them is keys()
which returns all the keys...
In your case, it will return:
MapIterator {"a", "b"}
and you easily convert them to an Array using ES6 ways, like spread operator...
const b = [...myMap.keys()];
This method doesn't require external libraries

ternary = simple form of if-else. It is available mostly for readability.
Note that probability is different than probability density pdf()
, which some of the previous answers refer to. Probability is the chance that the variable has a specific value, whereas the probability density is the chance that the variable will be near a specific value, meaning probability over a range. So to obtain the probability you need to compute the integral of the probability density function over a given interval. As an approximation, you can simply multiply the probability density by the interval you're interested in and that will give you the actual probability.
import numpy as np
from scipy.stats import norm
data_start = -10
data_end = 10
data_points = 21
data = np.linspace(data_start, data_end, data_points)
point_of_interest = 5
mu = np.mean(data)
sigma = np.std(data)
interval = (data_end - data_start) / (data_points - 1)
probability = norm.pdf(point_of_interest, loc=mu, scale=sigma) * interval
The code above will give you the probability that the variable will have an exact value of 5 in a normal distribution between -10 and 10 with 21 data points (meaning interval is 1). You can play around with a fixed interval value, depending on the results you want to achieve.
Using static cast would probably result in something like this:
// This does not prevent a possible type overflow
const char char_max = -1;
int i = 48;
char c = (i & char_max);
To prevent possible type overflow you could do this:
const char char_max = (char)(((unsigned char) char(-1)) / 2);
int i = 128;
char c = (i & char_max); // Would always result in positive signed values.
Where reinterpret_cast would probably just directly convert to char, without any cast safety. -> Never use reinterpret_cast if you can also use static_cast. If you're casting between classes, static_cast will also ensure, that the two types are matching (the object is a derivate of the cast type).
If your object a polymorphic type and you don't know which one it is, you should use dynamic_cast which will perform a type check at runtime and return nullptr if the types do not match.
IF you need const_cast you most likely did something wrong and should think about possible alternatives to fix const correctness in your code.
Just try below script:

I think I found a more general regexp to validate urls, particularly websites
?(https?:\/\/)?(www\.)[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,4}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)|(https?:\/\/)?(www\.)?(?!ww)[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,4}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)
it does not allow for instance www.something or http://www or http://www.something

SELECT 'SQL Server 2000'
ELSE IF ( @ver = '9' )
SELECT 'SQL Server 2005'

You should not care. If size is a concern I would use byte, short, int, then long. The only reason you would use an int larger than int32 is if you need a number higher than 2147483647 or lower than -2147483648.
Other than that I wouldn't care, there are plenty of other items to be concerned with.
This is set background color on even and odd li:

If you use the Logcat display inside the 'debug' perspective in Eclipse the lines are colour-coded. It's pretty easy to find what made your app crash because it's usually in red.
The Java (or Dalvik) virtual machine should never crash, but if your program throws an exception and does not catch it the VM will terminate your program, which is the 'crash' you are seeing.
Here is a class that can be used to setup and run ordered tests independent of MS Ordered Tests framework for whatever reason--like not have to adjust mstest.exe arguments on a build machine, or mixing ordered with non-ordered in a class.
The original testing framework only sees the list of ordered tests as a single test so any init/cleanup like [TestInitalize()] Init() is only called before and after the entire set.
Usage:
[TestMethod] // place only on the list--not the individuals
public void OrderedStepsTest()
{
OrderedTest.Run(TestContext, new List<OrderedTest>
{
new OrderedTest ( T10_Reset_Database, false ),
new OrderedTest ( T20_LoginUser1, false ),
new OrderedTest ( T30_DoLoginUser1Task1, true ), // continue on failure
new OrderedTest ( T40_DoLoginUser1Task2, true ), // continue on failure
// ...
});

It's better and safer to add to your LoginController.php the following code, that runs only after the standard logout:
use AuthenticatesUsers;
protected function loggedOut(Request $request)
{
return redirect('/new/redirect/you/want');
}

Its 100% guaranteed to work.
Though checkdate
is good, this seems much concise function to validate and also you can give formats. [Source]
function validateDate($date, $format = 'Y-m-d H:i:s') {
$d = DateTime::createFromFormat($format, $date);
return $d && $d->format($format) == $date;
}
function was copied from this answer or php.net
The extra ->format()
is needed for cases where the date is invalid but createFromFormat
still manages to create a DateTime object. For example:
// Gives "2016-11-10 ..." because Thursday falls on Nov 10
DateTime::createFromFormat('D M j Y', 'Thu Nov 9 2016');
// false, Nov 9 is a Wednesday
validateDate('Thu Nov 9 2016', 'D M j Y');
Structure is a data type. You don't give values to a data type. You give values to instances/objects of data types.
So no this is not possible in C.
Instead you can write a function which does the initialization for structure instance.
Alternatively, You could do:
struct MyStruct_s
{
int id;
} MyStruct_default = {3};
typedef struct MyStruct_s MyStruct;
And then always initialize your new instances as:
MyStruct mInstance = MyStruct_default;
I used a BoxLayout
and set its second parameter as BoxLayout.Y_AXIS
and it worked for me:
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
which(df==my.val, arr.ind=TRUE)
You could use this recursive function for generate necessary T-SQL script.

Something you can try is using the bind method, I think this achieves what you were asking for. If nothing else, it's still very useful.

diffElem.addEventListener('click', func.bind(diffElem, elem))

console.log(elem);
// 'this' and elem can be the same thing if the first parameter
// of the bind method is the element the event is being attached to from the argument passed to doClick
console.log(evt);

You almost had it, just need to escape special regex chars:
regex = /http\:\/\/www\.youtube\.com\/watch\?v=([\w-]{11})/;
url = 'http://www.youtube.com/watch?v=Ahg6qcgoay4';
id = url.match(regex)[1]; // id = 'Ahg6qcgoay4'
Edit: Fix for regex by soupagain.
Here is what I had and what caused my "incomplete type error":
#include "X.h" // another already declared class
class Big {...} // full declaration of class A
class Small : Big {
Small() {}
Small(X); // line 6
}
//.... all other stuff
What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..
Small::Big(X my_x) { // line 9 <--- LOOK at this !
}
I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..
Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.
Mixaz's above answer worked for me. However I had issues installing the package because of PGP check failures. Installing it by skipping the signature worked, you could try this :
yaourt --m-arg "--skipchecksums --skippgpcheck" -Sb <your-package>
Netbeans hints:
You get code completion on $users[0]->
and for $this->
for an array of User classes.
/**
* @var User[]
*/
var $users = array();
You also can see the type of the array in a list of class members when you do completion of $this->...
As @Astariul said, path to the file might cause this bug.
In addition, any parent directory which contains non-ASCII character, for example Chinese, will cause this.
In that case, you should rename you parent directory
You can use this extension I test it over
import Foundation
import UIKit
extension NSMutableAttributedString {
convenience init (fullString: String, fullStringColor: UIColor, subString: String, subStringColor: UIColor) {
let rangeOfSubString = (fullString as NSString).range(of: subString)
let rangeOfFullString = NSRange(location: 0, length: fullString.count)//fullString.range(of: fullString)
let attributedString = NSMutableAttributedString(string:fullString)
attributedString.addAttribute(NSAttributedStringKey.foregroundColor, value: fullStringColor, range: rangeOfFullString)
attributedString.addAttribute(NSAttributedStringKey.foregroundColor, value: subStringColor, range: rangeOfSubString)
self.init(attributedString: attributedString)
}
}
Try this:
schtasks /change /ENABLE /tn "Auto Restart" /s mycomutername /u mycomputername\username/p mypassowrd
Try
safeRunCommand() {
"$@"
if [ $? != 0 ]; then
printf "Error when executing command: '$1'"
exit $ERROR_CODE
fi
}
I saw that someone was wondering how to do it for another controller.
In my case I had all of my email templates in the Views/Email folder, but you could modify this to pass in the controller in which you have views associated for.
public static string RenderViewToString(Controller controller, string viewName, object model)
{
var oldController = controller.RouteData.Values["controller"].ToString();
if (controller.GetType() != typeof(EmailController))
controller.RouteData.Values["controller"] = "Email";
var oldModel = controller.ViewData.Model;
controller.ViewData.Model = model;
try
{
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindView(controller.ControllerContext, viewName,
null);
var viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
viewResult.View.Render(viewContext, sw);
//Cleanup
controller.ViewData.Model = oldModel;
controller.RouteData.Values["controller"] = oldController;
return sw.GetStringBuilder().ToString();
}
}
catch (Exception ex)
{
Elmah.ErrorSignal.FromCurrentContext().Raise(ex);
throw ex;
}
}
Essentially what this does is take a controller, such as AccountController and modify it to think it's an EmailController so that the code will look in the Views/Email
folder. It's necessary to do this because the FindView
method doesn't take a straight up path as a parameter, it wants a ControllerContext
.
Once done rendering the string, it returns the AccountController back to its initial state to be used by the Response object.
In cmd
, you can do this:
copy one.txt+two.txt+three.txt four.txt
In PowerShell this would be:
cmd /c copy one.txt+two.txt+three.txt four.txt
While the PowerShell way would be to use gc, the above will be pretty fast, especially for large files. And it can be used on on non-ASCII files too using the /B
switch.
Not necessarily the best practice, but my environment was a local network with several machines which needed access to the selenium.
When running the chromedriver, you can pass through a param like so :
chromedriver --whitelisted-ips=""
This will basically whitelist all IP's, not always an ideal solution of course and be careful with it for production enviornments, but you should be presented with a verbose warning :
Starting ChromeDriver 2.16.333244 (15fb740a49ab3660b8f8d496cfab2e4d37c7e6ca) on port 9515 All remote connections are allowed. Use a whitelist instead!
A work-around at best, but it works.
If you're trying to grab a range with a dynamically generated string, then you just have to build the string like this:
Range(firstcol & firstrow & ":" & secondcol & secondrow).Select
For the UITextField text comparison I am using below code and working fine for me, let me know if you find any error.
if(txtUsername.text.isEmpty || txtPassword.text.isEmpty)
{
//Do some stuff
}
else if(txtUsername.text == "****" && txtPassword.text == "****")
{
//Do some stuff
}
If you are developing spring boot application add "SpringBootServletInitializer" as shown in following code to your main file. Because without SpringBootServletInitializer Tomcat will consider it as normal application it will not consider as Spring boot application
@SpringBootApplication
public class DemoApplication extends *SpringBootServletInitializer*{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication .class);
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication .class, args);
}
}
sizes=( $(cat files.txt | xargs ls -l | cut -c 23-30) )
total=$(( $(IFS="+"; echo "${sizes[*]}") ))
Or you could just sum them as you read the sizes
declare -i total=0
while read x; total+=x; done < <( cat files.txt | xargs ls -l | cut -c 23-30 )
If you don't care about bite sizes and blocks is OK, then just
declare -i total=0
while read s junk; total+=s; done < <( cat files.txt | xargs ls -s )
I had this issue when trying to use a SOCKS proxy. It appears that SoapUI does not support SOCKS proxys. I am using the Boomerang Chrome app instead.
Here is what you are looking for:
Service hangs up at WaitForExit after calling batch file
It's about a question as to why a service can't execute a file, but it shows all the code necessary to do so.
You can use cURL and CRON to run .php files at set times.
Here's an example of what cURL needs to run the .php file:
curl http://localhost/myscript.php
Then setup the CRON job to run the above cURL:
nano -w /var/spool/cron/root
or
crontab -e
Followed by:
01 * * * * /usr/bin/curl http://www.yoursite.com/script.php
For more info about, check out this post: https://www.scalescale.com/tips/nginx/execute-php-scripts-automatically-using-cron-curl/
For more info about cURL: What is cURL in PHP?
For more info about CRON: http://code.tutsplus.com/tutorials/scheduling-tasks-with-cron-jobs--net-8800
Also, if you would like to learn about setting up a CRON job on your hosted server, just inquire with your host provider, and they may have a GUI for setting it up in the c-panel (such as http://godaddy.com, or http://1and1.com/ )
NOTE: Technically I believe you can setup a CRON job to run the .php file directly, but I'm not certain.
Best of luck with the automatic PHP running :-)
Active Directory is refusing access to your SQL Agent. The Agent should be running under an account that is recognized by STAR domain controller.
Short answer: While it's technically possible to send 100k e-mails each week yourself, the simplest, easiest and cheapest solution is to outsource this to one of the companies that specialize in it (I did say "cheapest": there's no limit to the amount of development time (and therefore money) that you can sink into this when trying to DIY).
Long answer: If you decide that you absolutely want to do this yourself, prepare for a world of hurt (after all, this is e-mail/e-fail we're talking about). You'll need:
mail()
is horrible enough by itself)Surprisingly, that was the easy part. The hard part is actually sending it:
And to top it off, you'll have to manage the legal part of it (various federal, state, and local laws; and even different tangles of laws once you send outside the U.S. (note: you have no way of finding if [email protected] lives in Southwest Elbonia, the country with world's most draconian antispam laws)).
I'm pretty sure I missed a few heads of this hydra - are you still sure you want to do this yourself? If so, there'll be another wave, this time merely the annoying problems inherent in sending an e-mail. (You see, SMTP is a store-and-forward protocol, which means that your e-mail will be shuffled across many SMTP servers around the Internet, in the hope that the next one is a bit closer to the final recipient. Basically, the e-mail is sent to an SMTP server, which puts it into its forward queue; when time comes, it will forward it further to a different SMTP server, until it reaches the SMTP server for the given domain. This forward could happen immediately, or in a few minutes, or hours, or days, or never.) Thus, you'll see the following issues - most of which could happen en route as well as at the destination:
<blink>
is not your friend here, nor is <font color=...>
)and it'll be your job to troubleshoot and solve this (hint: you can't, mostly). The people who run a legit mass-mailing businesses know that in the end you can't solve it, and that they can't solve it either - and they have the reasons well researched, documented and outlined (maybe even as a Powerpoint presentation - complete with sounds and cool transitions - that your bosses can understand), as they've had to explain this a million times before. Plus, for the problems that are actually solvable, they know very well how to solve them.
If, after all this, you are not discouraged and still want to do this, go right ahead: it's even possible that you'll find a better way to do this. Just know that the road ahead won't be easy - sending e-mail is trivial, getting it delivered is hard.
First, stop your Tomcat, then double click your server, click Server Locations
and check Use Tomcat Installation (takes control of Tomcat installation)
.
If you want to check only if two arrays have same values (regardless the number of occurrences and order of each value) you could do this by using lodash:
_.isEmpty(_.xor(array1, array2))
Short, simple and pretty!
there's nothing wrong with your file. xlrd does not yet support xlsx (excel 2007+) files although it's purported to have supported this for some time.
2-days ago they committed a pre-alpha version to their git which integrates xlsx support. Other forums suggest that you use a DOM parser for xlsx files since the xlsx file type is just a zip archive containing XML. I have not tried this. there is another package with similar functionality as xlrd and this is called openpyxl which you can get from easy_install or pip. I have not tried this either, however, its API is supposed to be similar to xlrd.
If you need to produce "real" Word documents you need a Windows-based web server and COM automation. I highly recommend Joel's article on this subject.
A rather common (but unreliable) alternative is:
header("Content-type: application/vnd.ms-word");
header("Content-Disposition: attachment; filename=document_name.doc");
echo "<html>";
echo "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=Windows-1252\">";
echo "<body>";
echo "<b>Fake word document</b>";
echo "</body>";
echo "</html>"
Make sure you don't use external stylesheets. Everything should be in the same file.
Note that this does not send an actual Word document. It merely tricks browsers into offering it as download and defaulting to a .doc
file extension. Older versions of Word may often open this without any warning/security message, and just import the raw HTML into Word. PHP sending sending that misleading Content-Type
header along does not constitute a real file format conversion.
This will work.
USE INFORMATION_SCHEMA;
SELECT TABLE_SCHEMA, TABLE_NAME
FROM information_schema.tables
WHERE TABLE_TYPE LIKE 'VIEW';
For getting the list of ip addresses associated, you can use netstat command
netstat -rn
This gives a long list of ip addresses and it is not easy to find the required field. The sample result is as following:
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.195.1 UGSc 17 0 en2
127 127.0.0.1 UCS 0 0 lo0
127.0.0.1 127.0.0.1 UH 1 254107 lo0
169.254 link#7 UCS 0 0 en2
192.168.195 link#7 UCS 3 0 en2
192.168.195.1 0:27:22:67:35:ee UHLWIi 22 397 en2 1193
192.168.195.5 127.0.0.1 UHS 0 0 lo0
More result is truncated.......
The ip address of gateway is in the first line; one with default at its first column.
To display only the selected lines of result, we can use grep command along with netstat
netstat -rn | grep 'default'
This command filters and displays those lines of result having default. In this case, you can see result like following:
default 192.168.195.1 UGSc 14 0 en2
If you are interested in finding only the ip address of gateway and nothing else you can further filter the result using awk. The awk command matches pattern in the input result and displays the output. This can be useful when you are using your result directly in some program or batch job.
netstat -rn | grep 'default' | awk '{print $2}'
The awk command tells to match and print the second column of the result in the text. The final result thus looks like this:
192.168.195.1
In this case, netstat displays all result, grep only selects the line with 'default' in it, and awk further matches the pattern to display the second column in the text.
You can similarly use route -n get default command to get the required result. The full command is
route -n get default | grep 'gateway' | awk '{print $2}'
These commands work well in linux as well as unix systems and MAC OS.
I had run into the same issue while I was dealing with large dataset. One thing I've noticed was the NoSuchElementException
is thrown when the Scanner reaches the endOfFile
, where it is not going to affect our data.
Here, I've placed my code in try block
and catch block
handles the exception
. You can also leave it empty, if you don't want to perform any task.
For the above question, because you are using file.next()
both in the condition and in the while loop you can handle the exception as
while(!file.next().equals(treasure)){
try{
file.next(); //stack trace error here
}catch(NoSuchElementException e) { }
}
This worked perfectly for me, if there are any corner cases for my approach, do let me know through comments.

If you are looking for a very extensible option or have a specific problem domain you could consider rolling your own using the Java Object Oriented Neural Engine. Another JOONE reference.
I used it successfully in a personal project to identify the letter from an image such as this, you can find all the source for the OCR component of my application on github, here.
Your title question and your example are completely different. I'll start by answering the title question:
$("a").removeAttr("href");
And as far as not requiring an href, the generally accepted way of doing this is:
<a href"#" onclick="doWork(); return false;">link</a>
The return false is necessary so that the href doesn't actually go anywhere.
That how I have done in kotlin
fun View.setTopMargin(@DimenRes dimensionResId: Int) {
(layoutParams as ViewGroup.MarginLayoutParams).topMargin = resources.getDimension(dimensionResId).toInt()
}

Well to obtain all different values in a Dataframe
you can use distinct. As you can see in the documentation that method returns another DataFrame
. After that you can create a UDF
in order to transform each record.
For example:
val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")
// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct
// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)
// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))
Just from reading that i would have never understood that "$@"
expands into a list of separate parameters. Whereas, "$*"
is one parameter consisting of all the parameters added together.
If it still makes no sense do this.

Technically, Node.js isn't proper JavaScript as we know it, since there isn't a Document Object Model (DOM). For instance, JavaScript scripts that run in the browser will not work. At all. The solution would be to run JavaScript with a headless browser. Fortunately there is a project still active: Mozilla Firefox has a headless mode.

Between the opening and closing tag in our case textarea tag shouldn't be space or newline character or any text(value).
If there's space, newline character or any text, it's considered as value which overrides placeholder.

**PlaceHolder Doesn't Appear**
<textarea placeholder="Am Default Message"> </textarea>
<textarea placeholder="Am Default Message">

If you want to get advantage of your local machine timezone you can use myDateTime.ToUniversalTime()
to get the UTC time from your local time or myDateTime.ToLocalTime()
to convert the UTC time to the local machine's time.
// convert UTC time from the database to the machine's time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var localTime = databaseUtcTime.ToLocalTime();
// convert local time to UTC for database save
var databaseUtcTime = localTime.ToUniversalTime();
If you need to convert time from/to other timezones, you may use TimeZoneInfo.ConvertTime()
or TimeZoneInfo.ConvertTimeFromUtc()
.
// convert UTC time from the database to japanese time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var japaneseTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
var japaneseTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, japaneseTimeZone);
// convert japanese time to UTC for database save
var databaseUtcTime = TimeZoneInfo.ConvertTimeToUtc(japaneseTime, japaneseTimeZone);
If you happen to be using jQuery, you might want to give this a shot: http://api.jquery.com/category/deferred-object/
It allows you to defer the execution of your callback function until the ajax request (or any async operation) is completed. This can also be used to call a callback once several ajax requests have all completed.
The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.
Instead, use sos (second-order sections) output of filter design.
from scipy.signal import butter, sosfilt, sosfreqz
def butter_bandpass(lowcut, highcut, fs, order=5):
nyq = 0.5 * fs
low = lowcut / nyq
high = highcut / nyq
sos = butter(order, [low, high], analog=False, btype='band', output='sos')
return sos
def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
sos = butter_bandpass(lowcut, highcut, fs, order=order)
y = sosfilt(sos, data)
return y
Also, you can plot frequency response by changing
b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)
to
sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)
If you want the actions to be more or less atomic, I would make sure to wrap them in a transaction. That way you can be sure both happened or both didn't happen as needed.
In vba the function is MOD. e.g
5 MOD 2
