FlagsAttribute, a small but nice feature when using enum to make a bitmasks:
[Flags]
public enum ConfigOptions
{
None = 0,
A = 1 << 0,
B = 1 << 1,
Both = A | B
}
Console.WriteLine( ConfigOptions.A.ToString() );
Console.WriteLine( ConfigOptions.Both.ToString() );
// Will print:
// A
// A, B
CSS:
tr {
width: 100%;
display: inline-table;
height:60px; // <-- the rows height
}
table{
height:300px; // <-- Select the height of the table
display: -moz-groupbox; // For firefox bad effect
}
tbody{
overflow-y: scroll;
height: 200px; // <-- Select the height of the body
width: 100%;
position: absolute;
}

Expanding on @MGA's Answer
While it's not possible to embed a video in Markdown you can "fake it" by including a valid linked image in your markup file, using this format:
[![IMAGE ALT TEXT](http://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg)](http://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE "Video Title")
If this markup snippet looks complicated, break it down into two parts:
an image
![image alt text](https://example.com/link-to-image)
wrapped in a link
[link text](https://example.com/my-link "link title")
We are sourcing the thumbnail image directly from YouTube and linking to the actual video, so when the person clicks the image/thumbnail they will be taken to the video.
[![Everything Is AWESOME](https://img.youtube.com/vi/StTqXEQ2l-Y/0.jpg)](https://www.youtube.com/watch?v=StTqXEQ2l-Y "Everything Is AWESOME")
OR If you want to give readers a visual cue that the image/thumbnail is actually a playable video, take your own screenshot of the video in YouTube and use that as the thumbnail instead.
[![Everything Is AWESOME](http://i.imgur.com/Ot5DWAW.png)](https://youtu.be/StTqXEQ2l-Y?t=35s "Everything Is AWESOME")
While this requires a couple of extra steps (a) taking the screenshot of the video and (b) uploading it so you can use the image as your thumbnail it does have 3 clear advantages:
Taking and uploading a screenshot takes a few seconds but has a big payoff.
Since this is standard markdown, it works everywhere. try it on GitHub, Reddit, Ghost, and here on Stack Overflow.
This approach also works with Vimeo videos
[![Little red riding hood](http://i.imgur.com/7YTMFQp.png)](https://vimeo.com/3514904 "Little red riding hood - Click to Watch!")
You can add that line to your console config file (e.g. .bashrc) , or to .profile
Here is another way without extra modules:
I needed to guess the environment from the task name, I have a 'dev' task and a 'prod' task.
When I run gulp prod
it should be set to prod environment.
When I run gulp dev
or anything else it should be set to dev environment.
For that I just check the running task name:
devEnv = process.argv[process.argv.length-1] !== 'prod';
I have solved this issue about $ sudo docker run hello-world
following the Docker doc.
If you are behind an HTTP Proxy server of corporate, this may solve your problem.
Docker doc also displays other situation about HTTP proxy setting.
There is a handy Debian and Ubuntu package called 'members' that provides this functionality:
Description: Shows the members of a group; by default, all members members is the complement of groups: whereas groups shows the groups a specified user belongs to, members shows users belonging to a specified group.
... You can ask for primary members, secondary members, both on one line, each on separate lines.
The previous answers are correct but it's generally a better practice to do:
import datetime
Then you'll have, using datetime.timedelta
:
date_1 = datetime.datetime.strptime(start_date, "%m/%d/%y")
end_date = date_1 + datetime.timedelta(days=10)
One big gotcha is that PHP is disabled in user home directories by default, so if you are testing from ~/public_html it doesn't work. Check /etc/apache2/mods-enabled/php5.conf
# Running PHP scripts in user directories is disabled by default
#
# To re-enable PHP in user directories comment the following lines
# (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it
# prevents .htaccess files from disabling it.
#<IfModule mod_userdir.c>
# <Directory /home/*/public_html>
# php_admin_flag engine Off
# </Directory>
#</IfModule>
Other than that installing in Ubuntu is real easy, as all the stuff you used to have to put in httpd.conf is done automatically.
In my case it was concurrent access to one Hibernate Session from several threads. I had the Spring Boot Batch and RepositoryItemReader implementation where I fetched entities by page request with size 10.
For example my entities are:
@Entity
class JobEntity {
@ManyToOne(fetch = FetchType.LAZY)
private GroupEntity group;
}
@Entity
class GroupEntity {
@OneToMany(mappedBy = "group", cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
private Set<Config> configs;
}
Batch process: reader -> processor -> writer
in one transaction.
In that entities configuration, GroupEntity can escapes to other threads:
First thread that entered to read section fetches the page of JobEntity with size 10 (RepositoryItemReader#doRead), this items contain one shared GroupEntity object (because all of them pointed to the same group id). Then it takes the first entity. Next threads that come to read section take JobEntity from this page one by one, until this page will be exhausted.
So now threads have access to the same GroupEntity instance thought the JobEntity instances, that is unsafe multi thread access to the one Hibernate Session.
Redirection of program output is performed by the shell.
grep ... > output.txt
grep
has no mechanism for adding blank lines between each match, but does provide options such as context around the matched line and colorization of the match itself. See the grep(1)
man page for details, specifically the -C
and --color
options.
I'm not sure of a way to do this in 3D, but in 2D you can use the compass
command.
$st = $data->prepare("SELECT * FROM exampleWHERE example LIKE :search LIMIT 10");
An executable file needs to have permissions for execute set before you can execute it.
In your machine where you are building the docker image (not inside the docker image itself) try running:
ls -la path/to/directory
The first column of the output for your executable (in this case docker-entrypoint.sh) should have the executable bits set something like:
-rwxrwxr-x
If not then try:
chmod +x docker-entrypoint.sh
and then build your docker image again.
Docker uses it's own file system but it copies everything over (including permissions bits) from the source directories.
Function:
public float simpleSimilarity(String u, String v) {
String[] a = u.split(" ");
String[] b = v.split(" ");
long correct = 0;
int minLen = Math.min(a.length, b.length);
for (int i = 0; i < minLen; i++) {
String aa = a[i];
String bb = b[i];
int minWordLength = Math.min(aa.length(), bb.length());
for (int j = 0; j < minWordLength; j++) {
if (aa.charAt(j) == bb.charAt(j)) {
correct++;
}
}
}
return (float) (((double) correct) / Math.max(u.length(), v.length()));
}
Test:
String a = "This is the first string.";
String b = "this is not 1st string!";
// for exact string comparison, use .equals
boolean exact = a.equals(b);
// For similarity check, there are libraries for this
// Here I'll try a simple example I wrote
float similarity = simple_similarity(a,b);
The out of memory suggestion doesn't seem like a bad lead.
What is your program doing that it gets this error?
Is it creating a great many windows or controls? Does it create them programatically as opposed to at design time? If so, do you do this in a loop? Is that loop infinite? Are you consuming staggering boatloads of memory in some other way?
What happens when you watch the memory used by your application in task manager? Does it skyrocket to the moon? Or better yet, as suggested above use process monitor to dive into the details.
Yes, if you use the SQL Server Agent.
Open your Enterprise Manager, and go to the Management folder under the SQL Server instance you are interested in. There you will see the SQL Server Agent, and underneath that you will see a Jobs section.
Here you can create a new job and you will see a list of steps you will need to create. When you create a new step, you can specify the step to actually run a stored procedure (type TSQL Script). Choose the database, and then for the command section put in something like:
exec MyStoredProcedure
That's the overview, post back here if you need any further advice.

Sometimes you need to call the base class' implementation, when you aren't in the derived function...It still works:
struct Base
{
virtual int Foo()
{
return -1;
}
};
struct Derived : public Base
{
virtual int Foo()
{
return -2;
}
};
int main(int argc, char* argv[])
{
Base *x = new Derived;
ASSERT(-2 == x->Foo());
//syntax is trippy but it works
ASSERT(-1 == x->Base::Foo());
return 0;
}
To find the sessions, as a DBA use
select sid,serial# from v$session where username = '<your_schema>'
If you want to be sure only to get the sessions that use SQL Developer, you can add and program = 'SQL Developer'
. If you only want to kill sessions belonging to a specific developer, you can add a restriction on os_user
Then kill them with
alter system kill session '<sid>,<serial#>'
(e.g.
alter system kill session '39,1232'
)
A query that produces ready-built kill-statements could be
select 'alter system kill session ''' || sid || ',' || serial# || ''';' from v$session where username = '<your_schema>'
This will return one kill statement per session for that user - something like:
alter system kill session '375,64855';
alter system kill session '346,53146';
You can do it like this
List<Value> list = new ArrayList<Value>(map.values());
On latest version of NPM you can just do:
npm install gitAuthor/gitRepo#tag
If the repo is a valid NPM package it will be auto-aliased in package.json as:
{
"NPMPackageName": "gitAuthor/gitRepo#tag"
}
If you could add this to @justingordon 's answer there is no need for manual aliasing now !
If you are inside of Spring bean (in this case @Controller
bean) you shouldn't use Spring context instance at all. Just autowire className
bean directly.
BTW, avoid using field injection as it's considered as bad practice.
First of all, the best answer for the literal question is
Hash === @some_var
But the question really should have been answered by showing how to do duck-typing here. That depends a bit on what kind of duck you need.
@some_var.respond_to?(:each_pair)
or
@some_var.respond_to?(:has_key?)
or even
@some_var.respond_to?(:to_hash)
may be right depending on the application.
This question was asked a long time ago so I thought I'd post an updated answer.
You should now avoid using @import
. Taken from the docs:
Sass will gradually phase it out over the next few years, and eventually remove it from the language entirely. Prefer the @use rule instead.
A full list of reasons can be found here
You should now use @use
as shown below:
_variables.scss
$text-colour: #262626;
_otherFile.scss
@use 'variables'; // Path to _variables.scss Notice how we don't include the underscore or file extension
body {
// namespace.$variable-name
// namespace is just the last component of its URL without a file extension
color: variables.$text-colour;
}
You can also create an alias for the namespace:
_otherFile.scss
@use 'variables' as v;
body {
// alias.$variable-name
color: v.$text-colour;
}
EDIT As pointed out by @und3rdg at the time of writing (November 2020) @use
is currently only available for Dart Sass and not LibSass (now deprecated) or Ruby Sass. See https://sass-lang.com/documentation/at-rules/use for the latest compatibility
//Different validations:
NSString * inputStr = @"Hey ";
//Check length
[inputStr length]
//Coming from server, check if its NSNull
[inputStr isEqual:[NSNull null]] ? nil : inputStr

-(BOOL)validateString:(NSString*)inputStr
{
BOOL isValid = NO;
if(!([inputStr length]>0))
{
return isValid;
}
NSMutableCharacterSet *allowedSet = [NSMutableCharacterSet characterSetWithCharactersInString:@".-"];
[allowedSet formUnionWithCharacterSet:[NSCharacterSet decimalDigitCharacterSet]];
if ([inputStr rangeOfCharacterFromSet:[allowedSet invertedSet]].location == NSNotFound)

Syntax: (Triple dot ... ) --> Means we can add zero or more objects pass in an arguments or pass an array of type object.
public static void main(String[] args){}
public static void main(String... args){}
Definition: 1) The Object ... argument is just a reference to an array of Objects.
2) ('String []' or String ... ) It can able to handle any number of string objects. Internally it uses an array of reference type object.
i.e. Suppose we pass an Object array to the ... argument - will the resultant argument value be a two-dimensional array - because an Object[] is itself an Object:
3) If you want to call the method with a single argument and it happens to be an array, you have to explicitly wrap it in
another. method(new Object[]{array});
OR
method((Object)array), which will auto-wrap.
Application: It majorly used when the number of arguments is dynamic(number of arguments know at runtime) and in overriding. General rule - In the method we can pass any types and any number of arguments. We can not add object(...) arguments before any specific arguments. i.e.
void m1(String ..., String s) this is a wrong approach give syntax error.
void m1(String s, String ...); This is a right approach. Must always give last order prefernces.
This is because the CHARINDEX-1 is returning a -ive value if the look-up for " " (space) is 0. The simplest solution would be to avoid '-ve' by adding
ABS(CHARINDEX(' ', PostCode ) -1))
which will return only +ive values for your length even if CHARINDEX(' ', PostCode ) -1)
is a -ve value. Correct me if I'm wrong!

I think you can use display as grid:
.parent { display: grid };
change them to rows
rows = zip(list1,list2,list3,list4,list5)
then just
import csv
with open(newfilePath, "w") as f:
writer = csv.writer(f)
for row in rows:
writer.writerow(row)
You should append to the table and not the rows.
<script type="text/javascript">
$('a').click(function() {
$('#myTable').append('<tr class="child"><td>blahblah<\/td></tr>');
});
</script>
You can use Procpath (author here), to simplify parsing of VmSwap
from /proc/$PID/status
.
$ procpath record -f stat,cmdline,status -r 1 -d db.sqlite
$ sqlite3 -column db.sqlite \
'SELECT status_name, status_vmswap FROM record ORDER BY status_vmswap DESC LIMIT 5'
Web Content 192136
okular 186872
thunderbird 183692
Web Content 143404
MainThread 86300
You can also plot VmSwap
of processes of interest over time like this. Here I'm recording my Firefox process tree while opening a couple tens of tabs along with statrting a memory-hungry application to try to cause it to swap (which wasn't convincing for Firefox, but your kilometrage may vary).
$ procpath record -f stat,cmdline,status -i 1 -d db2.sqlite \
'$..children[?(@.stat.pid == 6029)]'
# interrupt by Ctrl+C
$ procpath plot -d db2.sqlite -q cpu --custom-value-expr status_vmswap \
--title "CPU usage, % vs Swap, kB"
class of my button is "input-addon btn btn-default fileinput-exists"
below code helped me
document.querySelector('.input-addon.btn.btn-default.fileinput-exists').click();
but I want to click second button, I have two buttons in my screen so I used querySelectorAll
var elem = document.querySelectorAll('.input-addon.btn.btn-default.fileinput-exists');
elem[1].click();
here elem[1] is the second button object that I want to click.

When x in seen
is True
:
x
's sequence 511, 256, 129, 68, 41, 32, 31, 31;Hence, it suffices to stop as soon as the current x
is greater than or equal to the previous one:
def is_square(n):
assert n > 1
previous = n
x = n // 2
while x * x != n:
x = (x + (n // x)) // 2
if x >= previous:
return False

Equivalence with the original algorithm tested for 1 < n < 10**7. On the same interval, this slightly simpler variant is about 1.4 times faster.

As the name suggests ClassNotFoundException
in Java is a subclass of java.lang.Exception
and Comes when Java Virtual Machine tries to load a particular class and doesn't found the requested class in classpath.
Another important point about this Exception is that, It is a checked Exception and you need to provide explicitly Exception handling while using methods which can possibly throw ClassNotFoundException
in java either by using try-catch block or by using throws clause.
public class ClassNotFoundException
extends ReflectiveOperationException
Thrown when an application tries to load in a class through its string name using:
but no definition for the class with the specified name could be found.
You can use:
git diff <commit>^ <commit> -- <path> | git apply
The notation <commit>^
specifies the (first) parent of <commit>
. Hence, this diff command picks the changes made to <path>
in the commit <commit>
.
Note that this won't commit anything yet (as git cherry-pick
does). So if you want that, you'll have to do:
git add <path>
git commit
@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.
I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).
For the record: The following snippet can help you to get details about input, textarea, select, button, a tags through a temp title when hover them.

var $form = $tag.closest( 'form' );

var tagName = this.tagName;
var options = [];
var hidden = [];

if ( $form.length ) {
$form.find( ':input[type="hidden"]' ).each( function( index, el ) {
hidden.push( "\t" + el.name + ' = ' + el.value );
} );
var formName = $form.prop( 'name' );
var formTitle = $form.prop( 'title' );
var formId = $form.prop( 'id' );
var formClass = $form.prop( 'class' );
formDetails +=
"\n\nFORM NAME: " + formName +

check the name of the database in a file where you established a connection.
When trying to get the Python logging system (import logging
) to emit low level debug log messages, it suprised me to discover that given:
requests --> urllib3 --> http.client.HTTPConnection
that only urllib3
actually uses the Python logging
system:
requests
nohttp.client.HTTPConnection
nourllib3
yesSure, you can extract debug messages from HTTPConnection
by setting:
HTTPConnection.debuglevel = 1
but these outputs are merely emitted via the print
statement. To prove this, simply grep the Python 3.7 client.py
source code and view the print statements yourself (thanks @Yohann):
curl https://raw.githubusercontent.com/python/cpython/3.7/Lib/http/client.py |grep -A1 debuglevel`
Presumably redirecting stdout in some way might work to shoe-horn stdout into the logging system and potentially capture to e.g. a log file.
urllib3
' logger not 'requests.packages.urllib3
'To capture urllib3
debug information through the Python 3 logging
system, contrary to much advice on the internet, and as @MikeSmith points out, you won’t have much luck intercepting:
log = logging.getLogger('requests.packages.urllib3')
instead you need to:
log = logging.getLogger('urllib3')
urllib3
to a log fileHere is some code which logs urllib3
workings to a log file using the Python logging
system:
import requests
import logging
from http.client import HTTPConnection # py3
# log = logging.getLogger('requests.packages.urllib3') # useless
log = logging.getLogger('urllib3') # works
log.setLevel(logging.DEBUG) # needed
fh = logging.FileHandler("requests.log")
log.addHandler(fh)
requests.get('http://httpbin.org/')
the result:
Starting new HTTP connection (1): httpbin.org:80
http://httpbin.org:80 "GET / HTTP/1.1" 200 3168
HTTPConnection.debuglevel
print() statementsIf you set HTTPConnection.debuglevel = 1
from http.client import HTTPConnection # py3
HTTPConnection.debuglevel = 1
requests.get('http://httpbin.org/')
you'll get the print statement output of additional juicy low level info:
send: b'GET / HTTP/1.1\r\nHost: httpbin.org\r\nUser-Agent: python-
requests/2.22.0\r\nAccept-Encoding: gzip, deflate\r\nAccept: */*\r\nConnection: keep-alive\r\n\r\n'
reply: 'HTTP/1.1 200 OK\r\n'
header: Access-Control-Allow-Credentials header: Access-Control-Allow-Origin
header: Content-Encoding header: Content-Type header: Date header: ...
Remember this output uses print
and not the Python logging
system, and thus cannot be captured using a traditional logging
stream or file handler (though it may be possible to capture output to a file by redirecting stdout).
To maximise all possible logging, you must settle for console/stdout output with this:
import requests
import logging
from http.client import HTTPConnection # py3
log = logging.getLogger('urllib3')
log.setLevel(logging.DEBUG)
# logging from urllib3 to console
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)
log.addHandler(ch)
# print statements from `http.client.HTTPConnection` to console/stdout
HTTPConnection.debuglevel = 1

StanleyH's answer was excellent, but it had one unfortunate bug: clicking the shaded area of the scrollbar no longer jumps to the selection you click. Instead, what you get is a very small and somewhat annoying increment in the position of the scrollbar.
Tested: 4 versions of Firefox (100% affected), 4 versions of Chrome (50% affected).
Here's my jsfiddle. You can get around this with by having an on/off (true/false) var that allows only one onScroll() event to trigger at a time:
var scrolling = false;
$(".wrapper1").scroll(function(){
if(scrolling) {
scrolling = false;
return true;
}
scrolling = true;
$(".wrapper2")
.scrollLeft($(".wrapper1").scrollLeft());
});
$(".wrapper2").scroll(function(){
if(scrolling) {
scrolling = false;
return true;
}
scrolling = true;
$(".wrapper1")
.scrollLeft($(".wrapper2").scrollLeft());
});
Problem Behavior With Accepted Answer :
Actually Desired Behavior :
So, just why does this happen? If you run through the code, you'll see that wrapper1 calls wrapper2's scrollLeft, and wrapper2 calls wrapper1's scrollLeft, and repeat this infinitely, so, we have an infinite loop problem. Or, rather: the continued scrolling of the user conflicts with wrapperx's call of the scrolling, an event conflict occurs, and the end result is no jumping in the scrollbars.
Hope this helps someone else out!
I have found a fairly simple way to do this.
Initially, through your Anaconda Prompt, you can follow the steps in this official Tensorflow site - here. You have to follow the steps as is, no deviation.
Later, you open the Anaconda Navigator. In Anaconda Navigator, go to Applications On --- section. Select the drop down list, after following above steps you must see an entry - tensorflow into it. Select tensorflow and let the environment load.
Then, select Jupyter Notebook in this new context, and install it, let the installation get over.
After that you can run the Jupyter notebook like the regular notebook in tensorflow environment.
I think if you want to add content directly to the body, the best way is:
document.body.innerHTML = document.body.innerHTML + "bla bla";
To replace it, use:
document.body.innerHTML = "bla bla";
There is this MarkerClusterer
client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:
There are many approaches for doing what you asked for:
You can read about them on the provided link above.
Marker Clusterer
uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.
I hope this is what you were looking for & this will solve your problem :)
Let’s look at how to filter a built-in JDK List and a MutableList using Eclipse Collections.
List<Integer> jdkList = Arrays.asList(1, 2, 3, 4, 5);
MutableList<Integer> ecList = Lists.mutable.with(1, 2, 3, 4, 5);
If you wanted to filter the numbers less than 3, you would expect the following outputs.
List<Integer> selected = Lists.mutable.with(1, 2);
List<Integer> rejected = Lists.mutable.with(3, 4, 5);
Here’s how you can filter using a Java 8 lambda as the Predicate
.
Assert.assertEquals(selected, Iterate.select(jdkList, each -> each < 3));
Assert.assertEquals(rejected, Iterate.reject(jdkList, each -> each < 3));
Assert.assertEquals(selected, ecList.select(each -> each < 3));
Assert.assertEquals(rejected, ecList.reject(each -> each < 3));
Here’s how you can filter using an anonymous inner class as the Predicate
.
Predicate<Integer> lessThan3 = new Predicate<Integer>()
{
public boolean accept(Integer each)
{
return each < 3;
}
};
Assert.assertEquals(selected, Iterate.select(jdkList, lessThan3));
Assert.assertEquals(selected, ecList.select(lessThan3));
Here are some alternatives to filtering JDK lists and Eclipse Collections MutableLists using the Predicates factory.
Assert.assertEquals(selected, Iterate.select(jdkList, Predicates.lessThan(3)));
Assert.assertEquals(selected, ecList.select(Predicates.lessThan(3)));
Here is a version that doesn't allocate an object for the predicate, by using the Predicates2 factory instead with the selectWith
method that takes a Predicate2
.
Assert.assertEquals(
selected, ecList.selectWith(Predicates2.<Integer>lessThan(), 3));
Sometimes you want to filter on a negative condition. There is a special method in Eclipse Collections for that called reject
.
Assert.assertEquals(rejected, Iterate.reject(jdkList, lessThan3));
Assert.assertEquals(rejected, ecList.reject(lessThan3));
The method partition
will return two collections, containing the elements selected by and rejected by the Predicate
.
PartitionIterable<Integer> jdkPartitioned = Iterate.partition(jdkList, lessThan3);
Assert.assertEquals(selected, jdkPartitioned.getSelected());
Assert.assertEquals(rejected, jdkPartitioned.getRejected());
PartitionList<Integer> ecPartitioned = gscList.partition(lessThan3);
Assert.assertEquals(selected, ecPartitioned.getSelected());
Assert.assertEquals(rejected, ecPartitioned.getRejected());
Note: I am a committer for Eclipse Collections.

Add the following line on the top of your file
require 'json'
Then you can use:
car = {:make => "bmw", :year => "2003"}
car.to_json
Alternatively, you can use:
JSON.generate({:make => "bmw", :year => "2003"})
I see this questions is realla old, but for that problem I wrote a recursive function to unset all values in an array. Recursive because its possible that values from the given array are also an array. So that works for me:
function empty_array(& $complete_array) {
foreach($complete_array as $ckey => $cvalue)
{
if (!is_array($cvalue)) {
$complete_array[$ckey] = "";
} else {
empty_array( $complete_array[$ckey]);
}
}
return $complete_array;
}
So with that i get the array with all keys and sub-arrays, but empty values.
This might be your script-free solution: http://davidwalsh.name/css-transform-rotate
It's supported in all browsers prefixed and, in IE10-11 and all still-used Firefox versions, unprefixed.
That means that if you don't care for old IEs (the bane of web designers) you can skip the -ms-
and -moz-
prefixes to economize space.
However, the Webkit browsers (Chrome, Safari, most mobile navigators) still need -webkit-
, and there's a still-big cult following of pre-Next Opera and using -o-
is sensate.
I know this topic is old, but for future people who could wonder the same question, another incredibly inefficient solution could be to do:
PersonModel.find({$where : 'this.favouriteFoods.indexOf("sushi") != -1'});
This avoids all optimisations by MongoDB so do not use in production code.
An easy solution which avoids looping over the ticklabes is to just use
This command automatically rotates the xaxis labels and adjusts their position. The default values are a rotation angle 30° and horizontal alignment "right". But they can be changed in the function call
fig.autofmt_xdate(bottom=0.2, rotation=30, ha='right')
The additional bottom
argument is equivalent to setting plt.subplots_adjust(bottom=bottom)
, which allows to set the bottom axes padding to a larger value to host the rotated ticklabels.
So basically here you have all the settings you need to have a nice date axis in a single command.
A good example can be found on the matplotlib page.
Please see a link for more details.

hi if are you new in android use this way Apply your view to make it gone GONE is one way, else, get hold of the parent view, and remove the child from there..... else get the parent layout and use this method an remove all child parentView.remove(child)
I would suggest using the GONE approach...
It's a bug or whatever but the removePersistentDomainForName
is not working while clearing all the NSUserDefaults
values.
So, better option is that to reset the PersistentDomain
and that you can do via following way:
NSUserDefaults.standardUserDefaults().setPersistentDomain(["":""], forName: NSBundle.mainBundle().bundleIdentifier!)
Not with pure CSS. The closest equivalent is this:
.class1, .class2 {
some stuff
}
.class2 {
some more stuff
}
On OSX (and Solaris, apparently), the mkfile
command is available as well:
mkfile 10g big_file
This makes a 10 GB file named "big_file". Found this approach here.

Since sync XHR is being deprecated, it's best not to rely on that. If you need to do a sync POST request, you can use the following helpers inside of a service to simulate a form post.
It works by creating a form with hidden inputs which is posted to the specified URL.
//Helper to create a hidden input
function createInput(name, value) {
return angular
.element('<input/>')
.attr('type', 'hidden')
.attr('name', name)
.val(value);
}
//Post data
function post(url, data, params) {
//Ensure data and params are an object
data = data || {};
params = params || {};
//Serialize params
const serialized = $httpParamSerializer(params);
const query = serialized ? `?${serialized}` : '';
//Create form
const $form = angular
.element('<form/>')
.attr('action', `${url}${query}`)
.attr('enctype', 'application/x-www-form-urlencoded')
.attr('method', 'post');
//Create hidden input data
for (const key in data) {
if (data.hasOwnProperty(key)) {
const value = data[key];
if (Array.isArray(value)) {
for (const val of value) {
const $input = createInput(`${key}[]`, val);
$form.append($input);
}
}
else {
const $input = createInput(key, value);
$form.append($input);
}
}
}
//Append form to body and submit
angular.element(document).find('body').append($form);
$form[0].submit();
$form.remove();
}
Modify as required for your needs.

Honestly I find it easiest to convert to a pandas Series or DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame({'data':np.array([0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1])})
print df['data'].value_counts()
Or this nice one-liner suggested by Robert Muil:
pd.Series([0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1]).value_counts()

String redirectURL = "http://whatever.com/myJSPFile.jsp";
response.sendRedirect(redirectURL);

Code that appends a list of parameters to an existing url using ES6 and jQuery:
class UrlBuilder {
static appendParametersToUrl(baseUrl, listOfParams) {
if (jQuery.isEmptyObject(listOfParams)) {
return baseUrl;
}
const newParams = jQuery.param(listOfParams);
let partsWithHash = baseUrl.split('#');
let partsWithParams = partsWithHash[0].split('?');
let previousParams = '?' + ((partsWithParams.length === 2) ? partsWithParams[1] + '&' : '');
let previousHash = (partsWithHash.length === 2) ? '#' + partsWithHash[1] : '';
return partsWithParams[0] + previousParams + newParams + previousHash;
}
}
Where listOfParams is like
const listOfParams = {
'name_1': 'value_1',
'name_2': 'value_2',
'name_N': 'value_N',
};
Example of Usage:
UrlBuilder.appendParametersToUrl(urlBase, listOfParams);
Fast tests:
url = 'http://hello.world';
console.log('=> ', UrlParameters.appendParametersToUrl(url, null));
// Output: http://hello.world
url = 'http://hello.world#h1';
console.log('=> ', UrlParameters.appendParametersToUrl(url, null));
// Output: http://hello.world#h1
url = 'http://hello.world';

There is a function specifically for this. It is called numpy.pad
a = np.array([[1,2,3], [2,3,4]])
b = np.pad(a, ((0, 0), (0, 1)), mode='constant', constant_values=0)
print b
>>> array([[1, 2, 3, 0],
[2, 3, 4, 0]])
Here is what it says in the docstring:
Pads an array.
Parameters
----------
array : array_like of rank N
Input array
pad_width : {sequence, array_like, int}
Number of values padded to the edges of each axis.
((before_1, after_1), ... (before_N, after_N)) unique pad widths
for each axis.
((before, after),) yields same before and after pad for each axis.
(pad,) or int is a shortcut for before = after = pad width for all
axes.
mode : str or function
One of the following string values or a user supplied function.
'constant'
Pads with a constant value.
'edge'
Pads with the edge values of array.
'linear_ramp'
Pads with the linear ramp between end_value and the
array edge value.
'maximum'
Pads with the maximum value of all or part of the
vector along each axis.
'mean'
Pads with the mean value of all or part of the
vector along each axis.
'median'
Pads with the median value of all or part of the
vector along each axis.
'minimum'
Pads with the minimum value of all or part of the
vector along each axis.
'reflect'
Pads with the reflection of the vector mirrored on
the first and last values of the vector along each
axis.
'symmetric'
Pads with the reflection of the vector mirrored
along the edge of the array.
'wrap'
Pads with the wrap of the vector along the axis.
The first values are used to pad the end and the
end values are used to pad the beginning.
<function>
Padding function, see Notes.
stat_length : sequence or int, optional
Used in 'maximum', 'mean', 'median', and 'minimum'. Number of
values at edge of each axis used to calculate the statistic value.
((before_1, after_1), ... (before_N, after_N)) unique statistic
lengths for each axis.
((before, after),) yields same before and after statistic lengths
for each axis.
(stat_length,) or int is a shortcut for before = after = statistic
length for all axes.
Default is ``None``, to use the entire axis.
constant_values : sequence or int, optional
Used in 'constant'. The values to set the padded values for each
axis.
((before_1, after_1), ... (before_N, after_N)) unique pad constants
for each axis.
((before, after),) yields same before and after constants for each
axis.
(constant,) or int is a shortcut for before = after = constant for
all axes.
Default is 0.
end_values : sequence or int, optional
Used in 'linear_ramp'. The values used for the ending value of the
linear_ramp and that will form the edge of the padded array.
((before_1, after_1), ... (before_N, after_N)) unique end values
for each axis.
((before, after),) yields same before and after end values for each
axis.
(constant,) or int is a shortcut for before = after = end value for
all axes.
Default is 0.
reflect_type : {'even', 'odd'}, optional
Used in 'reflect', and 'symmetric'. The 'even' style is the
default with an unaltered reflection around the edge value. For
the 'odd' style, the extented part of the array is created by
subtracting the reflected values from two times the edge value.
Returns
-------
pad : ndarray
Padded array of rank equal to `array` with shape increased
according to `pad_width`.
Notes
-----
.. versionadded:: 1.7.0
For an array with rank greater than 1, some of the padding of later
axes is calculated from padding of previous axes. This is easiest to
think about with a rank 2 array where the corners of the padded array
are calculated by using padded values from the first axis.
The padding function, if used, should return a rank 1 array equal in
length to the vector argument with padded values replaced. It has the
following signature::
padding_func(vector, iaxis_pad_width, iaxis, kwargs)
where
vector : ndarray
A rank 1 array already padded with zeros. Padded values are
vector[:pad_tuple[0]] and vector[-pad_tuple[1]:].
iaxis_pad_width : tuple
A 2-tuple of ints, iaxis_pad_width[0] represents the number of
values padded at the beginning of vector where
iaxis_pad_width[1] represents the number of values padded at
the end of vector.
iaxis : int
The axis currently being calculated.
kwargs : dict
Any keyword arguments the function requires.

The question, essentially, is "how to concatenate arrays in Ruby". Naturally the answer is to use concat
or +
as mentioned in nearly every answer.
A natural extension to the question would be "how to perform row-wise concatenation of 2D arrays in Ruby". When I googled "ruby concatenate matrices", this SO question was the top result so I thought I would leave my answer to that (unasked but related) question here for posterity.
In some applications you might want to "concatenate" two 2D arrays row-wise. Something like,
[[a, b], | [[x], [[a, b, x],
[c, d]] | [y]] => [c, d, y]]
This is something like "augmenting" a matrix. For example, I used this technique to create a single adjacency matrix to represent a graph out of a bunch of smaller matrices. Without this technique I would have had to iterate over the components in a way that could have been error prone or frustrating to think about. I might have had to do an each_with_index
, for example. Instead I combined zip and flatten as follows,
# given two multi-dimensional arrays that you want to concatenate row-wise
m1 = [[:a, :b], [:c, :d]]
m2 = [[:x], [:y]]
m1m2 = m1.zip(m2).map(&:flatten)
# => [[:a, :b, :x], [:c, :d, :y]]

$dbc
is returning false. Your query has an error in it:
SELECT users.*, profile.* --You do not join with profile anywhere.
FROM users
INNER JOIN contact_info
ON contact_info.user_id = users.user_id
WHERE users.user_id=3");
The fix for this in general has been described by Raveren.
The pull
command is:
adb pull source dest
When you write:
adb pull /data/data/path.to.package/databases/data /sdcard/test
It means that you'll pull from /data/data/path.to.package/databases/data
and you'll copy it to /sdcard/test
, but the destination MUST be a local directory. You may write C:\Users\YourName\temp
instead.
For example:
adb pull /data/data/path.to.package/databases/data c:\Users\YourName\temp
This also work proper in chrome and internet Explorer
$("#MainContent_cmbEvalStatus").prop("selectedIndex", 1).change();
Put according your choice possition value of DropDown 0,1,2,3,4.....

$.ajax()
is the most configurable one, where you get fine grained control over HTTP headers and such. You're also able to get direct access to the XHR-object using this method. Slightly more fine-grained error-handling is also provided. Can therefore be more complicated and often unecessary, but sometimes very useful. You have to deal with the returned data yourself with a callback.
$.get()
is just a shorthand for $.ajax()
but abstracts some of the configurations away, setting reasonable default values for what it hides from you. Returns the data to a callback. It only allows GET-requests so is accompanied by the $.post()
function for similar abstraction, only for POST
.load()
is similar to $.get()
but adds functionality which allows you to define where in the document the returned data is to be inserted. Therefore really only usable when the call only will result in HTML. It is called slightly differently than the other, global, calls, as it is a method tied to a particular jQuery-wrapped DOM element. Therefore, one would do: $('#divWantingContent').load(...)
It should be noted that all $.get()
, $.post()
, .load()
are all just wrappers for $.ajax()
as it's called internally.

The answer by webmat is perfect. I just want to point you to a addition. If you have to deal a lot with command line parameters for your scripts, you should use optparse. It is simple and helps you tremendously.
YES - solution is to save workbook in to XML file (eg. 'XML Spreadsheet 2003') and edit this file as text in notepad! use "SEARCH" function of notepad to find query text and change your data to "?".
save and open in excel, try refresh data and excel will be monit about parameters.

Just to update this thread, here is how to add a list (as a json array) into JSONObject. Plz substitute YourClass with your class name;
List<YourClass> list = new ArrayList<>();
JSONObject jsonObject = new JSONObject();
org.codehaus.jackson.map.ObjectMapper objectMapper = new
org.codehaus.jackson.map.ObjectMapper();
org.codehaus.jackson.JsonNode listNode = objectMapper.valueToTree(list);
org.json.JSONArray request = new org.json.JSONArray(listNode.toString());
jsonObject.put("list", request);

Java Object Serialization
Serialization
is a mechanism to transform a graph of Java objects into an array of bytes for storage(to disk file
) or transmission(across a network
), then by using deserialization we can restore the graph of objects.
Graphs of objects are restored correctly using a reference sharing mechanism. But before storing, check whether serialVersionUID from input-file/network and .class file serialVersionUID are the same. If not, throw a java.io.InvalidClassException
.
Each versioned class must identify the original class version for which it is capable of writing streams and from which it can read. For example, a versioned class must declare:
serialVersionUID Syntax
// ANY-ACCESS-MODIFIER static final long serialVersionUID = (64-bit has)L; private static final long serialVersionUID = 3487495895819393L;
serialVersionUID is essential to the serialization process. But it is optional for the developer to add it into the java source file. If a serialVersionUID is not included, the serialization runtime will generate a serialVersionUID and associate it with the class. The serialized object will contain this serialVersionUID along with other data.
Note - It is strongly recommended that all serializable classes explicitly declare a serialVersionUID, since the default serialVersionUID computation is highly sensitive to class details that may vary depending on compiler implementations
, and can thus result in unexpected serialVersionUID conflicts during deserialization, causing deserialization to fail.
Inspecting Serializable Classes
A Java object is only serializable. if a class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable.
A class must implement java.io.Serializable interface in order to serialize its object successfully. Serializable is a marker interface and used to inform the compiler that the class implementing it has to be added serializable behavior. Here Java Virtual Machine (JVM) is responsible for its automatic serialization.
transient Keyword:
java.io.Serializable interface
While serializing an object, if we don't want certain data members of the object to be serialized we can use the transient modifier. The transient keyword will prevent that data member from being serialized.
- Fields declared as transient or static are ignored by the serialization process.
+--------------+--------+-------------------------------------+ | Flag Name | Value | Interpretation | +--------------+--------+-------------------------------------+ | ACC_VOLATILE | 0x0040 | Declared volatile; cannot be cached.| +--------------+--------+-------------------------------------+ |ACC_TRANSIENT | 0x0080 | Declared transient; not written or | | | | read by a persistent object manager.| +--------------+--------+-------------------------------------+
class Employee implements Serializable {
private static final long serialVersionUID = 2L;
static int id;
int eno;
String name;
transient String password; // Using transient keyword means its not going to be Serialized.
}
Implementing the Externalizable interface allows the object to assume complete control over the contents and format of the object's serialized form. The methods of the Externalizable interface, writeExternal and readExternal, are called to save and restore the objects state. When implemented by a class they can write and read their own state using all of the methods of ObjectOutput and ObjectInput. It is the responsibility of the objects to handle any versioning that occurs.
class Emp implements Externalizable {
int eno;
String name;
transient String password; // No use of transient, we need to take care of write and read.
@Override
public void writeExternal(ObjectOutput out) throws IOException {
out.writeInt(eno);
out.writeUTF(name);
//out.writeUTF(password);
}
@Override
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
this.eno = in.readInt();
this.name = in.readUTF();
//this.password = in.readUTF(); // java.io.EOFException
}
}
Only objects that support the java.io.Serializable or java.io.Externalizable interface can be written to
/read from
streams. The class of each serializable object is encoded including the class name and signature of the class, the values of the object's fields and arrays, and the closure of any other objects referenced from the initial objects.
Serializable Example For Files
public class SerializationDemo {
static String fileName = "D:/serializable_file.ser";
public static void main(String[] args) throws IOException, ClassNotFoundException, InstantiationException, IllegalAccessException {
Employee emp = new Employee( );
Employee.id = 1; // Can not Serialize Class data.
emp.eno = 77;
emp.name = "Yash";
emp.password = "confidential";

/*String stubHost = "127.0.0.1";
Integer anyFreePort = 7777;
socketRead(anyFreePort); //Thread1
socketWrite(emp, stubHost, anyFreePort); //Thread2*/
}
public static void objects_WriteRead( Employee obj, String serFilename ) throws IOException{
FileOutputStream fos = new FileOutputStream( new File( serFilename ) );
ObjectOutputStream objectOut = new ObjectOutputStream( fos );
objectOut.writeObject( obj );
objectOut.close();
fos.close();
System.out.println("Data Stored in to a file");
try {

ObjectInputStream ois = new ObjectInputStream( fis );
Object readObject;
readObject = ois.readObject();
String calssName = readObject.getClass().getName();
System.out.println("Restoring Class Name : "+ calssName); // InvalidClassException
Employee emp = (Employee) readObject;

obj.writeExternal( objectOut );
objectOut.flush();
fos.close();
System.out.println("Data Stored in to a file");
try {
// create a new instance and read the assign the contents from stream.
Emp emp = new Emp();

ObjectInputStream ois = new ObjectInputStream( fis );
emp.readExternal(ois);
System.out.format("Obj[No:%s, Name:%s, Pass:%s]", emp.eno, emp.name, emp.password);

} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
Serializable Example Over Network
Distributing object's state across different address spaces, either in different processes on the same computer, or even in multiple computers connected via a network, but which work together by sharing data and invoking methods.
/**
* Creates a stream socket and connects it to the specified port number on the named host.
*/
public static void socketWrite(Employee objectToSend, String stubHost, Integer anyFreePort) {
try { // CLIENT - Stub[marshalling]
Socket client = new Socket(stubHost, anyFreePort);
ObjectOutputStream out = new ObjectOutputStream(client.getOutputStream());
out.writeObject(objectToSend);
out.flush();
client.close();
} catch (IOException e) {
e.printStackTrace();
}
}
// Creates a server socket, bound to the specified port.
public static void socketRead( Integer anyFreePort ) {
try { // SERVER - Stub[unmarshalling ]
ServerSocket serverSocket = new ServerSocket( anyFreePort );
System.out.println("Server serves on port and waiting for a client to communicate");
/*System.in.read();
System.in.read();*/
Socket socket = serverSocket.accept();
System.out.println("Client request to communicate on port server accepts it.");
ObjectInputStream in = new ObjectInputStream(socket.getInputStream());
Employee objectReceived = (Employee) in.readObject();
System.out.println("Server Obj : "+ objectReceived.name );
socket.close();
serverSocket.close();
} catch (IOException | ClassNotFoundException e) {
e.printStackTrace();
}
}
@see
Two points not otherwise mentioned here that I find significant:
1) cout
carries a lot of baggage if you're not already using the STL. It adds over twice as much code to your object file as printf
. This is also true for string
, and this is the major reason I tend to use my own string library.
2) cout
uses overloaded <<
operators, which I find unfortunate. This can add confusion if you're also using the <<
operator for its intended purpose (shift left). I personally don't like to overload operators for purposes tangential to their intended use.
Bottom line: I'll use cout
(and string
) if I'm already using the STL. Otherwise, I tend to avoid it.
Mathias Bynens has compiled a list of well-known URL regexes with test URLs. There is little reason to write a new regular expression; just pick an existing one that suits you best.
But the comparison table for those regexes also shows that it is next to impossible to do URL validation with a single regular expression. All of the regexes in Bynens' list produce false positives and false negatives.
I suggest that you use an existing URL parser (for example new URL('http://www.example.com/')
in JavaScript) and then apply the checks you want to perform against the parsed and normalized form of the URL resp. its components. Using the JavaScript URL
interface has the additional benefit that it will only accept such URLs that are really accepted by the browser.
You should also keep in mind that technically incorrect URLs may still work. For example http://w_w_w.example.com/
, http://www..example.com/
, http://123.example.com/
all have an invalid hostname part but every browser I know will try to open them without complaints, and when you specify IP addresses for those invalid names in /etc/hosts/
such URLs will even work but only on your computer.
The question is, therefore, not so much whether a URL is valid, but rather which URLs work and should be allowed in a particular context.
If you want to do URL validation there are a lot of details and edge cases that are easy to overlook:
http://user:[email protected]/
.http://www.stackoverflow.com.
). [-0-9a-zA-z]
is definitely no longer sufficient.co.uk
and many others).Which of these limitations and rules apply is a question of project requirements and taste.
I have recently written a URL validator for a web app that is suitable for user-supplied URLs in forums, social networks, or the like. Feel free to use it as a base for your own one:
I have also written a blog post The Gory Details of URL Validation with more in-depth information.
You can also use this very simplified form:
@Html.ActionLink("Come back to Home", "Index", "Home")
Where :
Come back to Home
is the text that will appear on the page
Index
is the view name
Home
is the controller name
I've been looking into this problem for myself for almost a day and finally had a breakthrough. Try this:
Setting the PYTHONPATH / PYTHONHOME variables
Right click the Computer icon in the start menu, go to properties.
On the left tab, go to Advanced system settings. In the window that comes up, go to the Advanced tab, then at the bottom click Environment Variables. Click in the list of user variables and start typing Python, and repeat for System variables, just to make certain that you don't have mis-set variables for PYTHONPATH or PYTHONHOME. Next, add new variables (I did in System rather than User, although it may work for User too): PYTHONPATH, set to C:\Python27\Lib. PYTHONHOME
, set to C:\Python27.
Hope this helps!
I do not know C#, but with a little guesswork I think I understand what
foo : int {
get { return getFoo(); }
set { setFoo(newValue); }
}
does. It looks very similar to what you have in Swift, but it's not the same: in Swift you do not have the getFoo
and setFoo
. That is not a little difference: it means you do not have any underlying storage for your value.
Swift has stored and computed properties.
A computed property has get
and may have set
(if it's writable). But the code in the getter and setter, if they need to actually store some data, must do it in other properties. There is no backing storage.
A stored property, on the other hand, does have backing storage. But it does not have get
and set
. Instead it has willSet
and didSet
which you can use to observe variable changes and, eventually, trigger side effects and/or modify the stored value. You do not have willSet
and didSet
for computed properties, and you do not need them because for computed properties you can use the code in set
to control changes.
JQUery has a .parents() method for moving up the DOM tree you can start there.
If you're interested in doing this a more semantic way I don't think using the REL attribute on a button is the best way to semantically define "this is the answer" in your code. I'd recommend something along these lines:
<p id="question1">
<label for="input1">Volume =</label>
<input type="text" name="userInput1" id="userInput1" />
<button type="button">Check answer</button>
<input type="hidden" id="answer1" name="answer1" value="3.93e-6" />
</p>
and
$("button").click(function () {
var correctAnswer = $(this).parent().siblings("input[type=hidden]").val();
var userAnswer = $(this).parent().siblings("input[type=text]").val();
validate(userAnswer, correctAnswer);
$("#messages").html(feedback);
});
Not quite sure how your validate and feedback are working, but you get the idea.
I'm going to assume that you know the path and filename of the image that you want to upload. Add this string to your NameValuePair
using image
as the key-name.
Sending images can be done using the HttpComponents libraries. Download the latest HttpClient (currently 4.0.1) binary with dependencies package and copy apache-mime4j-0.6.jar
and httpmime-4.0.1.jar
to your project and add them to your Java build path.
You will need to add the following imports to your class.
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
Now you can create a MultipartEntity
to attach an image to your POST request. The following code shows an example of how to do this:
public void post(String url, List<NameValuePair> nameValuePairs) {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
try {
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
for(int index=0; index < nameValuePairs.size(); index++) {
if(nameValuePairs.get(index).getName().equalsIgnoreCase("image")) {
// If the key equals to "image", we use FileBody to transfer the data
entity.addPart(nameValuePairs.get(index).getName(), new FileBody(new File (nameValuePairs.get(index).getValue())));
} else {
// Normal string data
entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue()));
}
}
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost, localContext);
} catch (IOException e) {
e.printStackTrace();
}
}
I hope this helps you a bit in the right direction.
You should only access Linux files system (those located in lxss folder) from inside WSL; DO NOT create/modify any files in lxss folder in Windows - it's dangerous and WSL will not see these files.
Files can be shared between WSL and Windows, though; put the file outside of lxss folder. You can access them via drvFS (/mnt
) such as /mnt/c/Users/yourusername/files
within WSL. These files stay synced between WSL and Windows.
For details and why, see: https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/
The answers mentioning adding @Transactional
are correct, but for simplicity you could just have your test class extends AbstractTransactionalJUnit4SpringContextTests
.
The System.out.println(cal_Two.getTime())
invocation returns a Date
from getTime()
. It is the Date
which is getting converted to a string for println
, and that conversion will use the default IST
timezone in your case.
You'll need to explicitly use DateFormat.setTimeZone()
to print the Date
in the desired timezone.
EDIT: Courtesy of @Laurynas, consider this:
TimeZone timeZone = TimeZone.getTimeZone("UTC");
Calendar calendar = Calendar.getInstance(timeZone);
SimpleDateFormat simpleDateFormat =
new SimpleDateFormat("EE MMM dd HH:mm:ss zzz yyyy", Locale.US);
simpleDateFormat.setTimeZone(timeZone);
System.out.println("Time zone: " + timeZone.getID());
System.out.println("default time zone: " + TimeZone.getDefault().getID());
System.out.println();
System.out.println("UTC: " + simpleDateFormat.format(calendar.getTime()));
System.out.println("Default: " + calendar.getTime());
$date=$year."-".$month."-".$day;
$new_date=date('Y-m-d', strtotime($dob));
$status=0;
$insert_date = date("Y-m-d H:i:s");
$latest_insert_id=0;
$insertSql="insert into participationDetail (formId,name,city,emailId,dob,mobile,status,social_media1,social_media2,visa_status,tnc_status,data,gender,insertDate)values('".$formid."','".$name."','".$city."','".$email."','".$new_date."','".$mobile."','".$status."','".$link1."','".$link2."','".$visa_check."','".$tnc_check."','".json_encode($detail_arr,JSON_HEX_APOS)."','".$gender."','".$insert_date."')";
I found this solution to be quite helpful. It uses C# 4.0 DynamicObject to wrap the ConfigurationManager. So instead of accessing values like this:
WebConfigurationManager.AppSettings["PFUserName"]
you access them as a property:
dynamic appSettings = new AppSettingsWrapper();
Console.WriteLine(appSettings.PFUserName);
EDIT: Adding code snippet in case link becomes stale:
public class AppSettingsWrapper : DynamicObject
{
private NameValueCollection _items;
public AppSettingsWrapper()
{
_items = ConfigurationManager.AppSettings;
}
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = _items[binder.Name];
return result != null;
}
}
for some reason, my.demo.service has the same level as src/ in eclise project explorer view. After I move my.demo.service under src/, it is fine. Seems I should not create new package in "Project Explorer" view in Eclipse...
But thank you for your response:)
Visual Studio e.g. 2019 In general be aware that the selected Platform (e.g. x64) in the configuration Dialog is the the same as the Platform You intend to debug with! (see picture for explanation)

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).
This is a good understanding of data-binding. I think you've got that down.
For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.
I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.
I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.
<div rotate-on-click="45"></div>
First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.
function rotate(deg, elem) {
$(elem).css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
}
function addRotateOnClick($elems) {
$elems.each(function(i, elem) {
var deg = 0;
$(elem).click(function() {
deg+= parseInt($(this).attr('rotate-on-click'), 10);
rotate(deg, this);
});
});
}
addRotateOnClick($('[rotate-on-click]'));
app.directive('rotateOnClick', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var deg = 0;
element.bind('click', function() {
deg+= parseInt(attrs.rotateOnClick, 10);
element.css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
});
}
};
});
Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link
function (or compile
function).
Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.
This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?
The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.
Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:
Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.
Here are some things that modern frameworks are providing:
Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.
If you need to destroy a planet and you have a Death Star, use the Death star.
Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.
In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:
<clock></clock>
Done.
Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.
Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.
THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.
Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.
Note: The question is about JavaScript, and this answer is about jQuery, which is wrong. This is an old answer, from times when jQuery was widespread.
Instead, I recommend understanding scopes and closures in JavaScript.
With jQuery you can just do this, no matter where the declaration is:
$my_global_var = 'my value';
And will be available everywhere.
I use it for making quick image galleries, when images are spread in different places, like so:
$gallery = $('img');
$current = 0;
$gallery.each(function(i,v){
// preload images
(new Image()).src = v;
});
$('div').eq(0).append('<a style="display:inline-block" class="prev">prev</a> <div id="gallery"></div> <a style="display:inline-block" class="next">next</a>');
$('.next').click(function(){
$current = ( $current == $gallery.length - 1 ) ? 0 : $current + 1;
$('#gallery').hide().html($gallery[$current]).fadeIn();
});
$('.prev').click(function(){
$current = ( $current == 0 ) ? $gallery.length - 1 : $current - 1;
$('#gallery').hide().html($gallery[$current]).fadeIn();
});
Tip: run this whole code in the console in this page ;-)
Can't you just try to replace the body content with the document.body handler?
if your page is this:
<html>
<body>
blablabla
<script type="text/javascript">
document.body.innerHTML="hi!";
</script>
</body>
</html>
Just use the document.body to replace the body.
This works for me. All the content of the BODY tag is replaced by the innerHTML you specify. If you need to even change the html tag and all childs you should check out which tags of the 'document.' are capable of doing so.
An example with javascript scripting inside it:
<html>
<body>
blablabla
<script type="text/javascript">
var changeme = "<button onClick=\"document.bgColor = \'#000000\'\">click</button>";
document.body.innerHTML=changeme;
</script>
</body>
This way you can do javascript scripting inside the new content. Don't forget to escape all double and single quotes though, or it won't work. escaping in javascript can be done by traversing your code and putting a backslash in front of all singe and double quotes.
Bare in mind that server side scripting like php doesn't work this way. Since PHP is server-side scripting it has to be processed before a page is loaded. Javascript is a language which works on client-side and thus can not activate the re-processing of php code.
SELECT tab.*,
row_number() OVER () as rnum
FROM tab;
Here's the relevant section in the docs.
P.S. This, in fact, fully matches the answer in the referenced question.
One easy way to accomplish this is combining what was posted in the original post into a single statement:
int numberOfRecords = dtFoo.Select("IsActive = 'Y'").Length;
Another way to accomplish this is using Linq methods:
int numberOfRecords = dtFoo.AsEnumerable().Where(x => x["IsActive"].ToString() == "Y").ToList().Count;
Note this requires including System.Linq
.
The delete
operator allows you to remove a property from an object.
The following examples all do the same thing.
// Example 1
var key = "Cow";
delete thisIsObject[key];
// Example 2
delete thisIsObject["Cow"];
// Example 3
delete thisIsObject.Cow;
If you're interested, read Understanding Delete for an in-depth explanation.
There is also a smaller one yet called "input-mini".
You can serialize the data as JSON, like this:
$.cookie("basket-data", JSON.stringify($("#ArticlesHolder").data()));
Then to get it from the cookie:
$("#ArticlesHolder").data(JSON.parse($.cookie("basket-data")));
This relies on JSON.stringify()
and JSON.parse()
to serialize/deserialize your data object, for older browsers (IE<8) include json2.js to get the JSON
functionality. This example uses the jQuery cookie plugin
Test-Path
can be used with a special syntax:
Test-Path variable:global:foo
This also works for environment variables ($env:foo
):
Test-Path env:foo
And for non-global variables (just $foo
inline):
Test-Path variable:foo
I had a different but still related configuration.
Could be a custom configuration section that hasn't been declared in configSections.
Just declare the section and the error should resolve itself.
According to Javascript Date Documentation, you can easily do this way:
var twoHoursBefore = new Date();
twoHoursBefore.setHours(twoHoursBefore.getHours() - 2);
And don't worry about if hours you set will be out of 0..23
range.
Date() object will update the date accordingly.
This is a very broad question, so I am going to give a broad answer.
That is all that I can tell from the above screenshot. However, if I were to speculate, you probably have an IO subsystem that is too slow to keep up with the demand. This could be caused by missing indexes or an actually too slow disk. Keep in mind, that 15000 reads for a single OLTP query is slightly high but not uncommon.
Sorry for coding with Kotlin. But I faced the same problem. I solved with the code below.
list.setOnItemClickListener{ _, view, _, _ ->
val text1 = view.find<TextView>(R.id.~~).text
}
You can put an id which shows a TextView that you want in "~~".
Hope it'll help someone!
You can easily solve this problem by getting the latest version of the Firebase Libraries for Android SDK.
You can get the latest library from https://firebase.google.com/docs/android/setup
Example:
Before:
implementation 'com.google.firebase:firebase-auth:10.6.0'
to
After:
implementation 'com.google.firebase:firebase-auth:16.0.4'
I was facing similar problem on Windows 7 x64 professional edition. Please note following steps to fix this problem.
tools.jar is missing from required path if you are using jdk1.7 x64 bit version.
Please install x86 version of jdk1.7
Set JDK_HOME="C:\Program Files (x86)\Java\jdk1.7.0_67" and update path environment variable as path="C:\Program Files (x86)\Java\jdk1.7.0_67\bin" Note: Linux put the proper path.
Launch 32 bit application from /android-studio\bin folder.
I tested and verified these steps on windows 7 with 32 bit jdk1.7
This is how you do a distinct count query. Note that you have to filter out the nulls.
var useranswercount = (from a in tpoll_answer
where user_nbr != null && answer_nbr != null
select user_nbr).Distinct().Count();
If you combine this with into your current grouping code, I think you'll have your solution.
You need to search the World from the top right search bar and delete the expired certificate. Make sure you selected Login and All items.
if you are working on dynamic permissions and any permission like ACCESS_FINE_LOCATION,ACCESS_COARSE_LOCATION giving error "cannot resolve method PERMISSION_NAME" in this case write you code with permission name and then rebuild your project this will regenerate the manifest(Manifest.permission) file.
For bash, store your command like this:
command="ls | grep -c '^'"
Run your command like this:
echo $command | bash
Using internal-ip:

The trick is to show/dismiss the dialog within AsyncTask during onPreExecute/onPostExecute as usual, though in case of orientation-change create/show a new instance of the dialog in the activity and pass its reference to the task.
public class MainActivity extends Activity {
private Button mButton;
private MyTask mTask = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MyTask task = (MyTask) getLastNonConfigurationInstance();
if(task != null){
mTask = task;
mTask.mContext = this;
mTask.mDialog = ProgressDialog.show(this, "", "", true);
}
mButton = (Button) findViewById(R.id.button1);
mButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
mTask = new MyTask(MainActivity.this);
mTask.execute();
}
});
}
@Override
public Object onRetainNonConfigurationInstance() {
String str = "null";
if(mTask != null){
str = mTask.toString();
mTask.mDialog.dismiss();
}
Toast.makeText(this, str, Toast.LENGTH_SHORT).show();
return mTask;
}
private class MyTask extends AsyncTask<Void, Void, Void>{
private ProgressDialog mDialog;
private MainActivity mContext;
public MyTask(MainActivity context){
super();
mContext = context;
}
protected void onPreExecute() {
mDialog = ProgressDialog.show(MainActivity.this, "", "", true);
}
protected void onPostExecute(Void result) {
mContext.mTask = null;
mDialog.dismiss();
}
@Override
protected Void doInBackground(Void... params) {
SystemClock.sleep(5000);
return null;
}
}
}
++i
is slightly more efficient due to its semantics:
++i; // Fetch i, increment it, and return it
i++; // Fetch i, copy it, increment i, return copy
For int-like indices, the efficiency gain is minimal (if any). For iterators and other heavier-weight objects, avoiding that copy can be a real win (particularly if the loop body doesn't contain much work).
As an example, consider the following loop using a theoretical BigInteger class providing arbitrary precision integers (and thus some sort of vector-like internals):
std::vector<BigInteger> vec;
for (BigInteger i = 0; i < 99999999L; i++) {
vec.push_back(i);
}
That i++ operation includes copy construction (i.e. operator new, digit-by-digit copy) and destruction (operator delete) for a loop that won't do anything more than essentially make one more copy of the index object. Essentially you've doubled the work to be done (and increased memory fragmentation most likely) by simply using the postfix increment where prefix would have been sufficient.
This happens because document.write
would overwrite your existing code therefore place your div
before your javascript code. e.g.:
CSS:
#mydiv {
visibility:hidden;
}
Inside your html file
<div id="mydiv">
<p>Hello world</p>
</div>
<script type="text/javascript">
document.getElementById('mydiv').style.visibility='visible';
</script>
Hope this was helpful
The ideal way is to use a dictionary that maps a word to it's count. But if you can't use that, you might want to use 2 lists - 1 storing the words, and the other one storing counts of words. Note that order of words and counts matters here. Implementing this would be hard and not very efficient.
I`ve aways use this:
<?php function fRand($len) {
$str = '';
$a = "abcdefghijklmnopqrstuvwxyz0123456789";
$b = str_split($a);
for ($i=1; $i <= $len ; $i++) {
$str .= $b[rand(0,strlen($a)-1)];
}
return $str;
} ?>
When you call it, sets the lenght of string.
<?php echo fRand([LENGHT]); ?>
You can also change the possible characters in the string $a
.
Kindly check Column ApplicationId datatype in Table aspnet_Users , ApplicationId column datatype should be uniqueidentifier .
*Your parameter order is passed wrongly , Parameter @id should be passed as first argument, but in your script it is placed in second argument..*
So error is raised..
Please refere sample script:
DECLARE @id uniqueidentifier
SET @id = NEWID()
Create Table #temp1(AppId uniqueidentifier)
insert into #temp1 values(@id)
Select * from #temp1
Drop Table #temp1
You could try to use ng-class
.
Here is my simple example:
http://plnkr.co/edit/wS3QkQ5dvHNdc6Lb8ZSF?p=preview
<div ng-repeat="object in objects">
<span ng-class="{'disabled': object.status}" ng-click="disableIt(object)">
{{object.value}}
</span>
</div>
The status is a custom attribute of object, you could name it whatever you want.
The disabled
in ng-class
is a CSS class name, the object.status
should be true
or false
You could change every object's status in function disableIt
.
In your Controller, you could do this:
$scope.disableIt = function(obj) {
obj.status = !obj.status
}
You can't, because IEnumerable
doesn't have an index at all... if you are sure your enumerable has less than int.MaxValue
elements (or long.MaxValue
if you use a long
index), you can:
Don't use foreach, and use a for
loop, converting your IEnumerable
to a generic enumerable first:
var genericList = list.Cast<object>();
for(int i = 0; i < genericList.Count(); ++i)
{
var row = genericList.ElementAt(i);
/* .... */
}
Have an external index:
int i = 0;
foreach(var row in list)
{
/* .... */
++i;
}
Get the index via Linq:
foreach(var rowObject in list.Cast<object>().Select((r, i) => new {Row=r, Index=i}))
{
var row = rowObject.Row;
var i = rowObject.Index;
/* .... */
}
In your case, since your IEnumerable
is not a generic one, I'd rather use the foreach
with external index (second method)... otherwise, you may want to make the Cast<object>
outside your loop to convert it to an IEnumerable<object>
.
Your datatype is not clear from the question, but I'm assuming object
since it's an items source (it could be DataGridRow
)... you may want to check if it's directly convertible to a generic IEnumerable<object>
without having to call Cast<object>()
, but I'll make no such assumptions.
The concept of an "index" is foreign to an IEnumerable
. An IEnumerable
can be potentially infinite. In your example, you are using the ItemsSource
of a DataGrid
, so more likely your IEnumerable
is just a list of objects (or DataRows
), with a finite (and hopefully less than int.MaxValue
) number of members, but IEnumerable
can represent anything that can be enumerated (and an enumeration can potentially never end).
Take this example:
public static IEnumerable InfiniteEnumerable()
{
var rnd = new Random();
while(true)
{
yield return rnd.Next();
}
}
So if you do:
foreach(var row in InfiniteEnumerable())
{
/* ... */
}
Your foreach
will be infinite: if you used an int
(or long
) index, you'll eventually overflow it (and unless you use an unchecked
context, it'll throw an exception if you keep adding to it: even if you used unchecked
, the index would be meaningless also... at some point -when it overflows- the index will be the same for two different values).
So, while the examples given work for a typical usage, I'd rather not use an index at all if you can avoid it.
More simple, just set the buttonTint color: (only works on api level 21 or above)
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/radio"
android:checked="true"
android:buttonTint="@color/your_color"/>
in your values/colors.xml put your color in this case a reddish one:
<color name="your_color">#e75748</color>
Result:
If you want to do it by code (also api 21 and above):
if(Build.VERSION.SDK_INT>=21)
{
ColorStateList colorStateList = new ColorStateList(
new int[][]{
new int[]{-android.R.attr.state_enabled}, //disabled
new int[]{android.R.attr.state_enabled} //enabled
},
new int[] {
Color.BLACK //disabled
,Color.BLUE //enabled
}
);
radio.setButtonTintList(colorStateList);//set the color tint list
radio.invalidate(); //could not be necessary
}
If you are using xampp you can find php.ini

C++ is a general-purpose programming language. It is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell Labs as an enhancement to the C programming language and originally named "C with Classes". It was renamed to C++ in 1983.
C++ is widely used in the software industry. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. Several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel, Borland and others.
Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms. It features tools for developing and debugging C++ code, especially code written for Windows API, DirectX and .NET Framework.
So the main difference between them is that they are different things. The former is a programming language, while the latter is a commercial integrated development environment (IDE).
functools.reduce and pd.concat are good solutions but in term of execution time pd.concat is the best.
from functools import reduce
import pandas as pd
dfs = [df1, df2, df3, ...]
nan_value = 0
# solution 1 (fast)
result_1 = pd.concat(dfs, join='outer', axis=1).fillna(nan_value)
# solution 2
result_2 = reduce(lambda df_left,df_right: pd.merge(df_left, df_right,
left_index=True, right_index=True,
how='outer'),
dfs).fillna(nan_value)
You can code like this:
$query_select = "SELECT * FROM shouts ORDER BY id DESC LIMIT 8;";
$result_select = mysql_query($query_select) or die(mysql_error());
$rows = array();
while($row = mysql_fetch_array($result_select))
$rows[] = $row;
foreach($rows as $row){
$ename = stripslashes($row['name']);
$eemail = stripcslashes($row['email']);
$epost = stripslashes($row['post']);
$eid = $row['id'];
$grav_url = "http://www.gravatar.com/avatar.php?gravatar_id=".md5(strtolower($eemail))."&size=70";
echo ('<img src = "' . $grav_url . '" alt="Gravatar">'.'<br/>');
echo $eid . '<br/>';
echo $ename . '<br/>';
echo $eemail . '<br/>';
echo $epost . '<br/><br/><br/><br/>';
}
As you can see, it's still need a loop while to get data from mysql_fetch_array

Actually you have a code compiled targeting a higher JDK (JDK 1.8 in your case) but at runtime you are supplying a lower JRE(JRE 7 or below).
you can fix this problem by adding target parameter while compilation
e.g. if your runtime target is 1.7, you should use 1.7 or below
javac -target 1.7 *.java
if you are using eclipse, you can sent this parameter at Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" = choose your runtime jre version or lower.
When set the new value of element, you need call trigger change.

is an iterator that points to const value (like a const T*
pointer); dereferencing it returns a reference to a constant value (const T&
) and prevents modification of the referenced value: it enforces const
-correctness.
When you have a const reference to the container, you can only get a const_iterator
.
Edited: I mentionned “The const_iterator
returns constant pointers” which is not accurate, thanks to Brandon for pointing it out.
Edit: For COW objects, getting a non-const iterator (or dereferencing it) will probably trigger the copy. (Some obsolete and now disallowed implementations of std::string
use COW.)
On some systems (Windows with VC springs to mind, currently), RAND_MAX
is ridiculously small, i. e. only 15 bit. When dividing by RAND_MAX
you are only generating a mantissa of 15 bit instead of the 23 possible bits. This may or may not be a problem for you, but you're missing out some values in that case.
Oh, just noticed that there was already a comment for that problem. Anyway, here's some code that might solve this for you:
float r = (float)((rand() << 15 + rand()) & ((1 << 24) - 1)) / (1 << 24);
Untested, but might work :-)
It sounds like you need to some background reading on what an FFT is (e.g. http://en.wikipedia.org/wiki/FFT). But to answer your questions:
Why does the x-axis (frequency) end at 500?
Because the input vector is length 1000. In general, the FFT of a length-N
input waveform will result in a length-N
output vector. If the input waveform is real, then the output will be symmetrical, so the first 501 points are sufficient.
Edit: (I didn't notice that the example padded the time-domain vector.)
The frequency goes to 500 Hz because the time-domain waveform is declared to have a sample-rate of 1 kHz. The Nyquist sampling theorem dictates that a signal with sample-rate fs
can support a (real) signal with a maximum bandwidth of fs/2
.
How do I know the frequencies are between 0 and 500?
See above.
Shouldn't the FFT tell me, in which limits the frequencies are?
No.
Does the FFT only return the amplitude value without the frequency?
The FFT simply assigns an amplitude (and phase) to every frequency bin.
The code you tried is in fact two statements. A DELETE
followed by a SELECT
.
You don't define TOP
as ordered by what.
For a specific ordering criteria deleting from a CTE or similar table expression is the most efficient way.
;WITH CTE AS
(
SELECT TOP 1000 *
FROM [mytab]
ORDER BY a1
)
DELETE FROM CTE
I think it's worth mentioning how the Underscore's _.each() works internally. The _.each(list, iteratee) checks if the passed list is an array object, or an object.
In the case that the list is an array, iteratee arguments will be a list element and index as in the following example:
var a = ['I', 'like', 'pancakes', 'a', 'lot', '.'];
_.each( a, function(v, k) { console.log( k + " " + v); });
0 I
1 like
2 pancakes
3 a
4 lot
5 .
On the other hand, if the list argument is an object the iteratee will take a list element and a key:
var o = {name: 'mike', lastname: 'doe', age: 21};
_.each( o, function(v, k) { console.log( k + " " + v); });
name mike
lastname doe
age 21
For reference this is the _.each() code from Underscore.js 1.8.3
_.each = _.forEach = function(obj, iteratee, context) {
iteratee = optimizeCb(iteratee, context);
var i, length;
if (isArrayLike(obj)) {
for (i = 0, length = obj.length; i < length; i++) {
iteratee(obj[i], i, obj);
}
} else {
var keys = _.keys(obj);
for (i = 0, length = keys.length; i < length; i++) {
iteratee(obj[keys[i]], keys[i], obj);
}
}
return obj;
};
Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Margin="0,0,0,0" Background="Transparent"
BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
<ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header" Margin="12,2,12,2"
RecognizesAccessKey="True">
<ContentPresenter.LayoutTransform>
<RotateTransform Angle="270" />
</ContentPresenter.LayoutTransform>
</ContentPresenter>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="Background" Value="Red" />
<Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Border" Property="Background" Value="DarkRed" />
<Setter TargetName="Border" Property="BorderBrush" Value="Black" />
<Setter Property="Foreground" Value="DarkGray" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Depending on what you want to achieve, Boost.Config might help you. It does not provide detection of the standard-version, but it provides macros that let you check for support of specific language/compiler-features.
What about $("ul#list li:not(.active)")
?
You might want to try the very new and simple CSS3 feature:
img {
object-fit: contain;
}
It preserves the picture ratio (as when you use the background-picture trick), and in my case worked nicely for the same issue.
Be careful though, it is not supported by IE (see support details here).
An alternative approach would be installing Microsoft ODBC Driver 13, then replace SQLOLEDB
with ODBC Driver 13 for SQL Server

Use crosstab()
from the tablefunc module.
SELECT * FROM crosstab(
$$SELECT user_id, user_name, rn, email_address
FROM (
SELECT u.user_id, u.user_name, e.email_address
, row_number() OVER (PARTITION BY u.user_id
ORDER BY e.creation_date DESC NULLS LAST) AS rn
FROM usr u
LEFT JOIN email_tbl e USING (user_id)
) sub
WHERE rn < 4
ORDER BY user_id
$$
, 'VALUES (1),(2),(3)'
) AS t (user_id int, user_name text, email1 text, email2 text, email3 text);
I used dollar-quoting for the first parameter, which has no special meaning. It's just convenient if you have to escape single quotes in the query string which is a common case:
Detailed explanation and instructions here:
And in particular, for "extra columns":
The special difficulties here are:
The lack of key names.
-> We substitute with row_number()
in a subquery.
The varying number of emails.
-> We limit to a max. of three in the outer SELECT
and use crosstab()
with two parameters, providing a list of possible keys.
Pay attention to NULLS LAST
in the ORDER BY
.

In case you did what the questioner hinted at (forgot to fork and just locally cloned a repo, made changes and now need to issue a pull request) you can get back on track:
A view model is a conceptual model of data. Its use is to for example either get a subset or combine data from different tables.
You might only want specific properties, so this allows you to only load those and not additional unneccesary properties
A segmentation fault is caused by a request for a page that the process does not have listed in its descriptor table, or an invalid request for a page that it does have listed (e.g. a write request on a read-only page).
A dangling pointer is a pointer that may or may not point to a valid page, but does point to an "unexpected" segment of memory.

the context.xml configuration didn't work for me. Tomcat 6.0.29 complains about the docBase being inside the appBase: ... For Tomcat 5 this did actually work.
So one solution is to put the application in the ROOT folder.
Another very simple solution is to put an index.jsp to ROOT that redirects to my application like this: response.sendRedirect("/MyApplicationXy");

This section of the boto3 documentation is helpful.
Here's what worked for me:
session = boto3.Session(profile_name='dev')
client = session.client('cloudfront')
It means your Java runtime version is 1.8, but your compiler version (javac) is 1.6. To simply solve it, just retreat the Java version from 1.8 to 1.6.
But if you don't want to change the Java runtime version, then do the following steps:
Commonly base64 it is used for images. if you like to decode an image (jpg in this example with org.apache.commons.codec.binary.Base64 package):
byte[] decoded = Base64.decodeBase64(imageJpgInBase64);
FileOutputStream fos = null;
fos = new FileOutputStream("C:\\output\\image.jpg");
fos.write(decoded);
fos.close();

We can use date -d option
1) Change format to "%Y-%m-%d" format i.e 20121212 to 2012-12-12
date -d '20121212' +'%Y-%m-%d'
2)Get next or last day from a given date=20121212. Like get a date 7 days in past with specific format
date -d '20121212 -7 days' +'%Y-%m-%d'
3) If we are getting date in some variable say dat
dat2=$(date -d "$dat -1 days" +'%Y%m%d')
The other answers are right, but when you're dealing with interfaces you cannot use typeof or instanceof because interfaces don't get compiled to javascript.
Instead you can use a typecast + function check typeguard to check your variable:
interface Car {
drive(): void;
honkTheHorn(): void;
}
interface Bike {
drive(): void;
ringTheBell(): void;
}
function start(vehicle: Bike | Car ) {
vehicle.drive();
// typecast and check if the function exists
if ((<Bike>vehicle).ringTheBell) {
const bike = (<Bike>vehicle);
bike.ringTheBell();
} else {
const car = (<Car>vehicle);
car.honkTheHorn();
}
}
And this is the compiled JavaScript in ES2017:
function start(vehicle) {
vehicle.drive();
if (vehicle.ringTheBell) {
const bike = vehicle;
bike.ringTheBell();
}
else {
const car = vehicle;
car.honkTheHorn();
}
}
Use encodeURIComponent()
to encode the string.
Eg.:
var product_list = encodeURIComponent(JSON.stringify(product_list));
You don't need to decode it since the web server automatically do the same.
This should work for you. Infact the one which you are thinking will also work:-
.......
DECLARE @returnvalue INT
EXEC @returnvalue = SP_One
.....
In the root folder where package.json
is located, run npm outdated
. You'll get outdated packages returned with some details. In those details, you'll see the current version number of the outdated package.
After then, open the package.json
file and manually change the version number of the corresponding package.
Then delete the node_modules
folder and run npm install
. It should solve this issue.
In "Package Explorer" view, Right click your test class, then "Build Path">>"Include", it should be OK.
Harish has the answer here - except you need to request manage_pages
permission when authenticating and then using the page-id

You can totally avoid disabling, it is painful since html form format won't send anything related to <p>
or some other label.
So you can instead put regular
<input text tag just before you have `/>
add this
readonly="readonly"
It wouldn't disable your text but wouldn't change by user so it work like <p>
and will send value through form. Just remove border if you would like to make it more like <p>
tag
1) The command is C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\sn -T {your.dll}
In the above example, the Microsoft SDK resides in C:\Program Files\Microsoft SDKs\Windows\v6.0A. Your environment may differ.
2) To get the public key token of any of your project, you can add sn.exe as part of your External Tools in Visual Studio. The steps are shown in this Microsoft link: How to: Create a Tool to Get the Public Key of an Assembly
you should check the radiobutton in the radiogroup like this:
radiogroup.check(IdOfYourButton)
Of course you first have to set an Id to your radiobuttons
EDIT: i forgot, radioButton.getId()
works as well, thx Ramesh
EDIT2:
android:checkedButton="@+id/my_radiobtn"
works in radiogroup xml
A correct snprintf
implementation:
int count = snprintf(NULL, 0, "%i", x);
Do not use "each". It is used for operations and changes in the same element. Use "map" to extract data from the element body and using it somewhere else.
$(function() {
$('form button').click(function() {
var allowSubmit = true;
$.each($('form input:text'), function(index, formField) {
if($(formField).val().trim().length == 0) {
alert('field is empty!');
allowSubmit = false;
}
});
return allowSubmit;
});
});
While several answers are similar, I still had an issue - the user would click the button several times, playing the audio over itself (either it was clicked by accident or they were just 'playing'....)
An easy fix:
var music = new Audio();
function playMusic(file) {
music.pause();
music = new Audio(file);
music.play();
}
Setting up the audio on load allowed 'music' to be paused every time the function is called - effectively stopping the 'noise' even if they user clicks the button several times (and there is also no need to turn off the button, though for user experience it may be something you want to do).
I had same sort of issue, I resolved it by getting direct access to internet. Also check Application Loader logs to see at which point it gets stuck.
Google Apps Script will not open automatically web pages, but it could be used to display a message with links, buttons that the user could click on them to open the desired web pages or even to use the Window object and methods like addEventListener() to open URLs.
It's worth to note that UiApp is now deprecated. From Class UiApp - Google Apps Script - Google Developers
Deprecated. The UI service was deprecated on December 11, 2014. To create user interfaces, use the HTML service instead.
The example in the HTML Service linked page is pretty simple,
Code.gs
// Use this code for Google Docs, Forms, or new Sheets.
function onOpen() {
SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
.createMenu('Dialog')
.addItem('Open', 'openDialog')
.addToUi();
}
function openDialog() {
var html = HtmlService.createHtmlOutputFromFile('index')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
.showModalDialog(html, 'Dialog title');
}

It seems you have the click event wrapped around a custom event name "pageinit", are you sure you're triggered the event before you click the button?
something like this:
$("#gender").trigger("pageinit");
I was having similar issues connecting to OpenSUSE 13.1 MySQL database with LibreOffice. Update LibreOffice to latest stable "Still" package, then make sure the database is accessible using a tool such as phpMyAdmin. Make sure your user is linked to localhost and not "%" (any). This worked for me, I am able to add data thru LibreOffice.
Side note - LibreOffice Base will not supply "native connection" via MySQL on first attempt, you will need to use the back button, then try again to see the options.
Hope this helps.
I would add one more thing to Marc's answer: The memberOf attribute can't contain wildcards, so you can't say something like "memberof=CN=SPS*", and expect it to find all groups that start with "SPS".
If you've already assigned the variables using the npm module dotenv
, then they should show up in your global variables. That module is here.
While running the debugger, go to your variables tab (right click to reopen if not visible) and then open "global" and then "process." There should then be an env section...
In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage
object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.
Consider using sessionStorage
directly:

to be the simplest method.
You can solve it like this:
git reset --hard sha
where sha
e.g.: 85a108ec5d8443626c690a84bc7901195d19c446
You can get the desired sha with the command:
git log
Try moving your layout xml from res/layout-land
to res/layout
folder
scanf()
.fgets()
to get an entire line.strtol()
to parse the line as an integer, checking if it consumed the entire line.char *end;
char buf[LINE_MAX];
do {
if (!fgets(buf, sizeof buf, stdin))
break;
// remove \n
buf[strlen(buf) - 1] = 0;
int n = strtol(buf, &end, 10);
} while (end != buf + strlen(buf));
For some reason, some of the other methods don't work until the field has been focused/blured/changed, or a submit has been attempted... this works for me.
$("#formid").data('validator').element('#element').valid();
Had to dig through the jquery.validate script to find it...
Set the html tag, too. This way no weird position hacks are required.
html, body {height: 100%}
