I've been searching for a simple HTML/JS code and I did not found any. Then, I wrote the code below using onkeyup="DelayedSubmission()"
.

One case where namespaces may not be so useful for achieving "static classes" is when using these classes to achieve composition over inheritance. Namespaces cannot be friends of classes and so cannot access private members of a class.
class Class {
public:
void foo() { Static::bar(*this); }
private:
int member{0};
friend class Static;
};
class Static {
public:
template <typename T>
static void bar(T& t) {
t.member = 1;
}
};
It's not defined in the ECMA JSON standard. And generally speaking, a lack of definition in a standard means, "Don't count on this working the same way everywhere."
If you're a gambler, "many" JSON engines will allow duplication and simply use the last-specified value. This:
var o = {"a": 1, "b": 2, "a": 3}
Becomes this:
Object {a: 3, b: 2}
But if you're not a gambler, don't count on it!
The clean
, install
and deploy
phases are valid lifecycle phases and invoking them will trigger all the phases preceding them, and the goals bound to these phases.
mvn clean install
This command invokes the clean
phase and then the install
phase sequentially:
clean
: removes files generated at build-time in a project's directory (target
by default)install
: installs the package into the local repository, for use as a dependency in other projects locally.mvn deploy
This command invokes the deploy
phase:
deploy
: copies the final package to the remote repository for sharing with other developers and projects.mvn release
This is not a valid phase nor a goal so this won't do anything. But if refers to the Maven Release Plugin that is used to automate release management. Releasing a project is done in two steps: prepare
and perform
. As documented:
Preparing a release goes through the following release phases:
- Check that there are no uncommitted changes in the sources
- Check that there are no SNAPSHOT dependencies
- Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
- Transform the SCM information in the POM to include the final destination of the tag
- Run the project tests against the modified POMs to confirm everything is in working order
- Commit the modified POMs
- Tag the code in the SCM with a version name (this will be prompted for)
- Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
- Commit the modified POMs
And then:
Performing a release runs the following release phases:
- Checkout from an SCM URL with optional tag
- Run the predefined Maven goals to release the project (by default, deploy site-deploy)
I like this solution best. Simple, scalable, responsive. The idea here is to create a zero-height outer div with bottom padding set to the aspect ratio of the video. The iframe is scaled to 100% in both width and height, completely filling the outer container. The outer container automatically adjusts its height according to its width, and the iframe inside adjusts itself accordingly.
<div style="position:relative; width:100%; height:0px; padding-bottom:56.25%;">
<iframe style="position:absolute; left:0; top:0; width:100%; height:100%"
src="http://www.youtube.com/embed/RksyMaJiD8Y">
</iframe>
</div>
The only variable here is the padding-bottom value in the outer div. It's 75% for 4:3 aspect ratio videos, and 56.25% for widescreen 16:9 aspect ratio videos.
I created a game framework sometime ago to work on Android and Desktop, the desktop part that handle sound maybe can be used as inspiration to what you need.
Here is the code for reference.

There is another way to do that without cast:
when(a.method(Matchers.<Class<A>>any())).thenReturn(b);
This solution forces the method any()
to return Class<A>
type and not its default value (Object
).
Try this part of code:
void containsOnlyNumbers(String str)
{
try {
Integer num = Integer.valueOf(str);
System.out.println("is a number");
} catch (NumberFormatException e) {
// TODO: handle exception
System.out.println("is not a number");
}
}

Convert.ChangeType()
doesn't correctly handle nullable types or enumerations in .NET 2.0 BCL (I think it's fixed for BCL 4.0 though). Rather than make the outer implementation more complex, make the converter do more work for you. Here's an implementation I use:
public static class Converter
{
public static T ConvertTo<T>(object value)
{
return ConvertTo(value, default(T));
}
public static T ConvertTo<T>(object value, T defaultValue)
{
if (value == DBNull.Value)
{
return defaultValue;
}
return (T) ChangeType(value, typeof(T));
}
public static object ChangeType(object value, Type conversionType)
{
if (conversionType == null)
{
throw new ArgumentNullException("conversionType");
}
// if it's not a nullable type, just pass through the parameters to Convert.ChangeType
if (conversionType.IsGenericType && conversionType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
{
// null input returns null output regardless of base type
if (value == null)
{
return null;
}
// it's a nullable type, and not null, which means it can be converted to its underlying type,
// so overwrite the passed-in conversion type with this underlying type
conversionType = Nullable.GetUnderlyingType(conversionType);
}
else if (conversionType.IsEnum)
{
// strings require Parse method
if (value is string)
{
return Enum.Parse(conversionType, (string) value);
}
// primitive types can be instantiated using ToObject
else if (value is int || value is uint || value is short || value is ushort ||
value is byte || value is sbyte || value is long || value is ulong)
{
return Enum.ToObject(conversionType, value);
}
else
{
throw new ArgumentException(String.Format("Value cannot be converted to {0} - current type is " +
"not supported for enum conversions.", conversionType.FullName));
}
}
return Convert.ChangeType(value, conversionType);
}
}
Then your implementation of GetQueryString<T> can be:
public static T GetQueryString<T>(string key)
{
T result = default(T);
string value = HttpContext.Current.Request.QueryString[key];
if (!String.IsNullOrEmpty(value))
{
try
{
result = Converter.ConvertTo<T>(value);
}
catch
{
//Could not convert. Pass back default value...
result = default(T);
}
}
return result;
}

TL;DR: Use StandardError
instead for general exception catching. When the original exception is re-raised (e.g. when rescuing to log the exception only), rescuing Exception
is probably okay.
Exception
is the root of Ruby's exception hierarchy, so when you rescue Exception
you rescue from everything, including subclasses such as SyntaxError
, LoadError
, and Interrupt
.
Rescuing Interrupt
prevents the user from using CTRLC to exit the program.
Rescuing SignalException
prevents the program from responding correctly to signals. It will be unkillable except by kill -9
.
Rescuing SyntaxError
means that eval
s that fail will do so silently.
All of these can be shown by running this program, and trying to CTRLC or kill
it:
loop do
begin
sleep 1
eval "djsakru3924r9eiuorwju3498 += 5u84fior8u8t4ruyf8ihiure"
rescue Exception
puts "I refuse to fail or be stopped!"
end
end
Rescuing from Exception
isn't even the default. Doing
begin
# iceberg!
rescue
# lifeboats
end
does not rescue from Exception
, it rescues from StandardError
. You should generally specify something more specific than the default StandardError
, but rescuing from Exception
broadens the scope rather than narrowing it, and can have catastrophic results and make bug-hunting extremely difficult.
If you have a situation where you do want to rescue from StandardError
and you need a variable with the exception, you can use this form:
begin
# iceberg!
rescue => e
# lifeboats
end
which is equivalent to:
begin
# iceberg!
rescue StandardError => e
# lifeboats
end
One of the few common cases where it’s sane to rescue from Exception
is for logging/reporting purposes, in which case you should immediately re-raise the exception:
begin
# iceberg?
rescue Exception => e
# do some logging
raise # not enough lifeboats ;)
end
If you don't want to add id's to your data, you could track by the index in the array, which will cause the items to be keyed by their position in the array instead of their value.
Like this:
var myArray = [1,1,1,1,1];
<li ng-repeat="item in myArray track by $index">
https://www.programmableweb.com/ -- Great collection of all category API's across web. It not only show cases the API's , but also Developers who use those API's in their applications and code samples, rating of the API and much more. They have more than apis they also have sdk and libraries too.
You cannot 'alter' the property syntax this way. What you can do is this:
class Foo
{
string MyProperty { get; set; } // auto-property with inaccessible backing field
}
and a generic version would look like this:
class Foo<T>
{
T MyProperty { get; set; }
}
SEL is a type that represents a selector in Objective-C. The @selector() keyword returns a SEL that you describe. It's not a function pointer and you can't pass it any objects or references of any kind. For each variable in the selector (method), you have to represent that in the call to @selector. For example:
-(void)methodWithNoParameters;
SEL noParameterSelector = @selector(methodWithNoParameters);
-(void)methodWithOneParameter:(id)parameter;
SEL oneParameterSelector = @selector(methodWithOneParameter:); // notice the colon here
-(void)methodWIthTwoParameters:(id)parameterOne and:(id)parameterTwo;
SEL twoParameterSelector = @selector(methodWithTwoParameters:and:); // notice the parameter names are omitted
Selectors are generally passed to delegate methods and to callbacks to specify which method should be called on a specific object during a callback. For instance, when you create a timer, the callback method is specifically defined as:
-(void)someMethod:(NSTimer*)timer;
So when you schedule the timer you would use @selector to specify which method on your object will actually be responsible for the callback:
@implementation MyObject
-(void)myTimerCallback:(NSTimer*)timer
{
// do some computations
if( timerShouldEnd ) {
[timer invalidate];
}
}
@end
// ...
int main(int argc, const char **argv)
{
// do setup stuff
MyObject* obj = [[MyObject alloc] init];
SEL mySelector = @selector(myTimerCallback:);
[NSTimer scheduledTimerWithTimeInterval:30.0 target:obj selector:mySelector userInfo:nil repeats:YES];
// do some tear-down
return 0;
}
In this case you are specifying that the object obj be messaged with myTimerCallback every 30 seconds.
Depending on how secure you need the configuration files or how reliable your application is, http://activemq.apache.org/encrypted-passwords.html may be a good solution for you.
If you are not too afraid of the password being decrypted and it can be really simple to configure using a bean to store the password key. However, if you need more security you can set an environment variable with the secret and remove it after launch. With this you have to worry about the application / server going down and not application not automatically relaunching.

Some checking code required of course, but easily implemented!
The following is what I use to commit changes on foo
to N=1
days in the past:
git add foo
git commit -m "Update foo"
git commit --amend --date="$(date -v-1d)"
If you want to commit to a even older date, say 3 days back, just change the date
argument: date -v-3d
.
That's really useful when you forget to commit something yesterday, for instance.
UPDATE: --date
also accepts expressions like --date "3 days ago"
or even --date "yesterday"
. So we can reduce it to one line command:
git add foo ; git commit --date "yesterday" -m "Update"
If you can use a simple delimiter, a very simple oneliner is this:
for i in a,b c_s,d ; do
KEY=${i%,*};
VAL=${i#*,};
echo $KEY" XX "$VAL;
done
Hereby i
is filled with character sequences like "a,b"
and "c_s,d"
. each separated by spaces. After the do
we use parameter substitution to extract the part before the comma ,
and the part after it.
don't do anything just type in your command prompt
C:\> sh
then you got like this
sh-4.4$
# type here
ssh-4.4$ ssh-keygen -t rsa -b 4096 -C "[email protected]"
this should must work.
Put your script in a file foo.py
starting with
#!/usr/bin/python
Then give execute permission to that script using
chmod a+x foo.py
and use the full path of your foo.py
file in your crontab
.
See documentation of execve(2) which is handling the shebang.
If you want to set styles of all elements in body you should use next code^
body{
color: green;
}
You can use the doubleValue of your string like
NSString *string=@"1.22";
double a=[string doubleValue];
i think this will return a as 0.0 if the string is invalid (it might throw an exception, in which case you can just catch it, the docs say 0.0 tho). more info here

Image provides an abstract access to an arbitrary image , it defines a set of methods that can loggically be applied upon any implementation of Image. Its not bounded to any particular image format or implementation . Bitmap is a specific implementation to the image abstract class which encapsulate windows GDI bitmap object. Bitmap is just a specific implementation to the Image abstract class which relay on the GDI bitmap Object.
You could for example , Create your own implementation to the Image abstract , by inheriting from the Image class and implementing the abstract methods.
Anyway , this is just a simple basic use of OOP , it shouldn't be hard to catch.
The most common representations are probably these two:
Of these two the adjacency matrix is the simplest, as long as you don't mind having a (possibly huge) n * n
array, where n
is the number of vertices. Depending on the base type of the array, you can even store edge weights for use in e.g. shortest path discovery algorithms.

Something like this should do it:
.column-left{ float: left; width: 33.333%; }
.column-right{ float: right; width: 33.333%; }
.column-center{ display: inline-block; width: 33.333%; }
EDIT
To do this with a larger number of columns you could build a very simple grid system. For example, something like this should work for a five column layout:
.column {_x000D_

I think you haven't edited codeigniter files to enable base_url(). you try to assign it in url_helper.php you also can do the same config/autoload.php file. you can add this code in your autoload.php
$autoload['helper'] = array('url');
Than You will be able to ue base_url() like this
<link rel="stylesheet" href="<?php echo base_url();?>/css/template/default.css" type="text/css" />

All the proposed approaches may give wrong results because they don’t take into account summer/winter time changes. Rather than calculating the number of days between two dates using the constant of 86’400’000 milliseconds, it is better to use an approach like the following one:
getDaysDiff = function (dateObject0, dateObject1) {
if (dateObject0 >= dateObject1) return 0;
var d = new Date(dateObject0.getTime());
var nd = 0;
while (d <= dateObject1) {
d.setDate(d.getDate() + 1);
nd++;
}
return nd-1;
};
If you use Android Studio .Open the SDK-Manager, checked "Show Package Details" you will find out "Android Wear ARM EABI v7a System Image" download it , success !
That only works for numbers less than 1.
select to_char(12.34, '0D99') from dual;
-- Result: #####
This won't work.
You could do something like this but this results in leading whitespaces:
select to_char(12.34, '999990D99') from dual;
-- Result: ' 12,34'
Ultimately, you could add a TRIM to get rid of the whitespaces again but I wouldn't consider that a proper solution either...
select trim(to_char(12.34, '999990D99')) from dual;
-- Result: 12,34
Again, this will only work for numbers with 6 digits max.
Edit: I wanted to add this as a comment on DCookie's suggestion but I can't.

The -t enables terminal emulation. Whether you need the terminal emulation for sudo depends on configuration (and by default you do no need it, while many distributions override the default). On the contrary, many other commands need terminal emulation.

To use like this:
var dataToSend = document.querySelector("form").serialize();
I hope I have helped.

It looks like others had this problem also, and there is a simple Python script now, for converting output of mysqldump into CSV files.
wget https://raw.githubusercontent.com/jamesmishra/mysqldump-to-csv/master/mysqldump_to_csv.py
mysqldump -u username -p --host=rdshostname database table | python mysqldump_to_csv.py > table.csv
The steps described above do work, however I've encountered this problem on IntelliJ IDEA and have found that I'm having these problems with existing projects and the only solution is to remove the 'appcompat' module (not the library) and re-import it.
0 for input, 1 for stdout and 2 for stderr.
One Tip:
somecmd >1.txt 2>&1
is correct, while somecmd 2>&1 >1.txt
is totally wrong with no effect!
What you are looking for is 'type casting'. typecasting (putting the type you know you want in brackets) tells the compiler you know what you are doing and are cool with it. The old way that is inherited from C is as follows.
float var_a = 9.99;
int var_b = (int)var_a;
If you had only tried to write
int var_b = var_a;
You would have got a warning that you can't implicitly (automatically) convert a float
to an int
, as you lose the decimal.
This is referred to as the old way as C++ offers a superior alternative, 'static cast'; this provides a much safer way of converting from one type to another. The equivalent method would be (and the way you should do it)
float var_x = 9.99;
int var_y = static_cast<int>(var_x);
This method may look a bit more long winded, but it provides much better handling for situations such as accidentally requesting a 'static cast' on a type that cannot be converted. For more information on the why you should be using static cast, see this question.
Right now you seem to be saying 'does this array of strings equal this string', which of course it never would.
Perhaps you should think about iterating through your array of strings with a loop, and checking each to see if they are equals() with the inputted string?
...or do I misunderstand your question?
use the get method in the url. If you want to pass over a variable called 'phone' as 0001112222:
<a href='whatever.php?phone=0001112222'>click</a>
then on the next page (whatever.php) you can access this var via:
$_GET['phone']
bad = []
good = [x for x in mylist if x in goodvals or bad.append(x)]
append returns None, so it works.
cURL is an option, using Ajax as well eventhough solving back-end problems with the front-end isn't so neat.
A very useful post about doing it without cURL is this one: http://netevil.org/blog/2006/nov/http-post-from-php-without-curl
The code to do this (untested, unimproved, from the blog post):
function do_post_request($url, $data, $optional_headers = null)
{
$params = array('http' => array(
'method' => 'POST',
'content' => $data
));
if ($optional_headers !== null) {
$params['http']['header'] = $optional_headers;
}
$ctx = stream_context_create($params);
$fp = @fopen($url, 'rb', false, $ctx);
if (!$fp) {
throw new Exception("Problem with $url, $php_errormsg");
}
$response = @stream_get_contents($fp);
if ($response === false) {
throw new Exception("Problem reading data from $url, $php_errormsg");
}
return $response;
}
please Find below one it helps me a lot to set data function
$('#datepicker').datepicker({dateFormat: 'yy-mm-dd'}).datepicker('setDate', '2010-07-25');
Thanks for spotting this I was about to add strings thinking the same as you that they'd get added to end of collection. It appears the params are:
msg.to.Add(<MailAddress>) adds MailAddress to the end of the collection
msg.to.Add(<string>) add a list of emails to the collection
Slightly different actions depending on param type, I think this is pretty bad form i'd have prefered split methods AddStringList of something.
You can set background color to All Scaffolds in application at once.
just set scaffoldBackgroundColor: in ThemeData
MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(scaffoldBackgroundColor: const Color(0xFFEFEFEF)),
home: new MyHomePage(title: 'Flutter Demo Home Page'),
);
Simple using html like this downloads the file mentioned using static keyword
<a href="{% static 'bt.docx' %}" class="btn btn-secondary px-4 py-2 btn-sm">Download CV</a>
For those who struggle with this:
const value = $('SELECTOR').iCheck('update')[0].checked;
This directly returns true
or false
as boolean
.
If you're dealing with very large strings, specifically multiline strings, be aware of the triple-quote syntax:
a = r"""This is a multiline string
with more than one line
in the source code."""
XCode 8.2, iOS 10, Swift 3: now there's an unselectedItemTintColor
attribute for tabBar
:
self.tabBar.unselectedItemTintColor = UIColor(red: 0/255.0, green: 200/255.0, blue: 0/255.0, alpha: 1.0)
What I have just experiment with VS diagnostic tools is I called this.Close() then formclosing event triggered. Then When I call this.Dispose() at the end in Formclosing event where I dispose many other objects in it, it cleans everything much much smoother.
This is an option:
dbContext.Entry(entity).State = EntityState.Detached;
In this case, it's probably because you are using the wrong brackets here:
document.getElementById['calendar'].src = loc;
should be
document.getElementById('calendar').src = loc;
I realize that you want to avoid reading the whole JSON file into memory if possible, however if you have the memory available it may not be a bad idea performance-wise. Using node.js's require() on a json file loads the data into memory really fast.
I ran two tests to see what the performance looked like on printing out an attribute from each feature from a 81MB geojson file.
In the 1st test, I read the entire geojson file into memory using var data = require('./geo.json')
. That took 3330 milliseconds and then printing out an attribute from each feature took 804 milliseconds for a grand total of 4134 milliseconds. However, it appeared that node.js was using 411MB of memory.
In the second test, I used @arcseldon's answer with JSONStream + event-stream. I modified the JSONPath query to select only what I needed. This time the memory never went higher than 82MB, however, the whole thing now took 70 seconds to complete!
You can make your own with:
>>> import os
>>> base=os.path.basename('/root/dir/sub/file.ext')
>>> base
'file.ext'
>>> os.path.splitext(base)
('file', '.ext')
>>> os.path.splitext(base)[0]
'file'
Important note: If there is more than one .
in the filename, only the last one is removed. For example:
/root/dir/sub/file.ext.zip -> file.ext
/root/dir/sub/file.ext.tar.gz -> file.ext.tar
See below for other answers that address that.
you try read link this
Error:Execution failed for task ‘:app:processDevDebugManifest’. Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.3.0) then usd VERSION 26.0.0
I kept using this all this time
Import-module .\build_functions.ps1 -Force
I declare them as undefined when I don't assign a value because they are undefined after all.
The following CSS works for me - Using Bootstrap 3. You need to add this css after boostrap styles -
.modal.fade .modal-dialog{
-webkit-transition-property: transform;
-webkit-transition-duration:0 ;
transition-property: transform;
transition-duration:0 ;
}
.modal.fade {
transition: none;
}
@echo off
setlocal enableextensions disabledelayedexpansion
set "search=%1"
set "replace=%2"
set "textFile=Input.txt"
for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
set "line=%%i"
setlocal enabledelayedexpansion
>>"%textFile%" echo(!line:%search%=%replace%!
endlocal
)
for /f
will read all the data (generated by the type
comamnd) before starting to process it. In the subprocess started to execute the type
, we include a redirection overwritting the file (so it is emptied). Once the do
clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.
The compiler cannot tell from that code if the function will ever reach the end and still return something. To make that clear, replace the last else if(...)
with just else
.
To add to the above answer (do steps 1-5).
Above answers are pretty correct, but some times Android Studio, does not like to refresh after SDK path change, a quick solution is to make some change in you Build file, and click on Sync. It will refresh you project.
Happy coding... :)

Have you considering using the Maven command-line to upload files?
mvn deploy:deploy-file \
-Durl=$REPO_URL \
-DrepositoryId=$REPO_ID \
-DgroupId=org.myorg \
-DartifactId=myproj \
-Dversion=1.2.3 \
-Dpackaging=zip \
-Dfile=myproj.zip
This will automatically generate the Maven POM for the artifact.
The following Sonatype article states that the "deploy-file" maven plugin is the easiest solution, but it also provides some examples using curl:
Try using an invisible element (or psuedoelement) to force the table-cell to expand.

You need to float all the buttons to left and make sure its width to fit within outer container.
CSS:
.btn{
float:left;
}
HTML:
<button type="submit" class="btn" onClick="return false;" >Save</button>
<button type="submit" class="btn" onClick="return false;">Publish</button>
<button class="btn">Back</button>
Should work.
Here's a working example:
Excerpt:
function loadIframe(iframeName, url) {
var $iframe = $('#' + iframeName);
if ($iframe.length) {
$iframe.attr('src',url);
return false;
}
return true;
}
I'm always running tests against an in-memory DB (HSQLDB or Derby) for these reasons:
The in-memory DB is loaded with fresh data once the tests start and after most tests, I invoke ROLLBACK to keep it stable. ALWAYS keep the data in the test DB stable! If the data changes all the time, you can't test.
The data is loaded from SQL, a template DB or a dump/backup. I prefer dumps if they are in a readable format because I can put them in VCS. If that doesn't work, I use a CSV file or XML. If I have to load enormous amounts of data ... I don't. You never have to load enormous amounts of data :) Not for unit tests. Performance tests are another issue and different rules apply.
I haven't seen this particular approach suggested, so here's a terse comparison method I like to use that works for both string
and number
types:
const objs = [
{ first_nom: 'Lazslo', last_nom: 'Jamf' },
{ first_nom: 'Pig', last_nom: 'Bodine' },
{ first_nom: 'Pirate', last_nom: 'Prentice' }
];
const sortBy = fn => {
const cmp = (a, b) => -(a < b) || +(a > b);
return (a, b) => cmp(fn(a), fn(b));
};
const getLastName = o => o.last_nom;
const sortByLastName = sortBy(getLastName);
objs.sort(sortByLastName);
console.log(objs.map(getLastName));
_x000D_
sortBy()
sortBy()
accepts a fn
that selects a value from an object to use in comparison, and returns a function that can be passed to Array.prototype.sort()
. In this example, we're comparing o.last_nom
. Whenever we receive two objects such as
a = { first_nom: 'Lazslo', last_nom: 'Jamf' }
b = { first_nom: 'Pig', last_nom: 'Bodine' }
we compare them with (a, b) => cmp(fn(a), fn(b))
. Given that
fn = o => o.last_nom
we can expand the comparison function to (a, b) => cmp(a.last_nom, b.last_nom)
. Because of the way logical OR (||
) works in JavaScript, cmp(a.last_nom, b.last_nom)
is equivalent to
if (a.last_nom < b.last_nom) return -1;
if (a.last_nom > b.last_nom) return 1;
return 0;
Incidentally, this is called the three-way comparison "spaceship" (<=>
) operator in other languages.
Finally, here's the ES5-compatible syntax without using arrow functions:
var objs = [
{ first_nom: 'Lazslo', last_nom: 'Jamf' },
{ first_nom: 'Pig', last_nom: 'Bodine' },
{ first_nom: 'Pirate', last_nom: 'Prentice' }
];
function sortBy(fn) {
function cmp(a, b) { return -(a < b) || +(a > b); }
return function (a, b) { return cmp(fn(a), fn(b)); };
}
function getLastName(o) { return o.last_nom; }
var sortByLastName = sortBy(getLastName);
objs.sort(sortByLastName);
console.log(objs.map(getLastName));

An alternative to services is to use the value store.
In the base of my app I added this
var agentApp = angular.module('rbAgent', ['ui.router', 'rbApp.tryGoal', 'rbApp.tryGoal.service', 'ui.bootstrap']);
agentApp.value('agentMemory',
{
contextId: '',
sessionId: ''
}
);
...
And then in my controller I just reference the value store. I don't think it holds thing if the user closes the browser.
angular.module('rbAgent')
.controller('AgentGoalListController', ['agentMemory', '$scope', '$rootScope', 'config', '$state', function(agentMemory, $scope, $rootScope, config, $state){
$scope.config = config;
$scope.contextId = agentMemory.contextId;

As of Bootstrap 3.x, there's an example of this in the docs here: http://getbootstrap.com/components/#input-groups-buttons-dropdowns
<div class="input-group">
<input type="text" class="form-control" aria-label="...">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Action <span class="caret"></span></button>
<ul class="dropdown-menu dropdown-menu-right" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
</div><!-- /input-group -->
This copies the 5 cells to the right of the activecell. If you have a range selected, the active cell is the top left cell in the range.
Sub Copy5CellsToRight()
ActiveCell.Offset(, 1).Resize(1, 5).Copy
End Sub
If you want to include the activecell in the range that gets copied, you don't need the offset:
Sub ExtendAndCopy5CellsToRight()
ActiveCell.Resize(1, 6).Copy
End Sub
Note that you don't need to select before copying.
If you're OK with littering your markup a bit, you could do it the easy way and just wrap your <button>
with an anchor (<a>
) link.
<a href="#/new-page.html"><button>New Page<button></a>
Also, there is nothing stopping you from styling an anchor link to look like a <button>
as pointed out in the comments by @tronman, this is not technically valid html5, but it should not cause any problems in practice
you also should specify def name in the project settings here:
Configuration > Properties/Input/Advanced/Module > Definition File
There is better way to do this.
DataTable targetDataTable = new DataTable(); targetDataTable = changedColumnMetadata.AsEnumerable().Where(dataRow => entityName.Equals(dataRow["EntityName"])).CopyToDataTable();
Please try this and let me know in case of any issues.
@Bolton 's answer worked for me. Some details...
I got my phone a few weeks ago. I tried the HelloAndroid sample app right away (after installing req'd software, etc.). The app worked in the emulator AND on the phone--right away!
Shortly after that, I rooted my phone but did not flash any roms or kernels. I was only experimenting on the emulator until yesterday (writing a simple notepad app). When I tried debugging the app on the phone, here's what I observed:
Eclipse console reported the "...failed to install on device...(null)" message. BUT
The HelloAndroid app DID get pushed to the phone! (It appeared in the apps drawer AND I was able to launch it.)
It simply would not launch on the phone from the Eclipse run.
I searched around here and elsewhere last night (including this thread) with no luck. Finally, I rebooted my phone--which I never tried (doh!) 'cause I didn't think it would make a difference--and the app launched from an Eclipse start!
Still don't know the cause, but I'll come back here if I figure it out.
The shortest code would be:
Select CAST((@EndDateTime-@StartDateTime) as time(0)) '[hh:mm:ss]'
Consider using strtok_r
, as others have suggested, or something like:
void printWords(const char *string) {
// Make a local copy of the string that we can manipulate.
char * const copy = strdup(string);
char *space = copy;
// Find the next space in the string, and replace it with a newline.
while (space = strchr(space,' ')) *space = '\n';
// There are no more spaces in the string; print out our modified copy.
printf("%s\n", copy);
// Free our local copy
free(copy);
}
In bootstrap 4, if you want to over-ride when navbar-expand-*, expands and collapses and shows and hides the hamburger (navbar-toggler) you have to find that style/definition in bootstrap.css, and redefine it in your own customstyle.css (or directly in bootstrap.css if you are so inclined).
Eg. I wanted the navbar-expand-lg to collapses and shows the navbar-toggler at 950px. In bootstrap.css I find:
@media (max-width: 991.98px) {
.navbar-expand-lg > .container,
.navbar-expand-lg > .container-fluid {
padding-right: 0;
padding-left: 0;
}
}
And below that ...
@media (min-width:992px) {
... lots of styling ...
}
I copied both @media queries and stuck them in my style.css, then modified the size to fit my needs. I my case I wanted it to collapse at 950px. The @media queries must need to be different sizes (I'm guessing), so I set container max-width to 949.98px and used the 950px for the other @media query and so the following code was appended to my style.css. This was not easy to detangle from twisted solutions I found on Stackoverflow and elsewhere. Hope this helps.
@media (max-width: 949.98px) {
.navbar-expand-lg > .container,
.navbar-expand-lg > .container-fluid {
padding-right: 0;
padding-left: 0;
}

This is related to Content-Type
. As you might have noticed from other discussions and answers to this question some people were able to solve it by setting Content-Type: 'application/json'
. Unfortunately in my case it didn't work, my POST request was still empty on the server side.
However, if you try with jQuery's $.post()
and it's working, the reason is probably because of jQuery using Content-Type: 'x-www-form-urlencoded'
instead of application/json
.
data = Object.keys(data).map(key => encodeURIComponent(key) + '=' + encodeURIComponent(data[key])).join('&')
fetch('/api/', {
method: 'post',
credentials: "include",
body: data,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})

if you want to append to a file
with open("test.txt", "a") as myfile:
myfile.write("append me")
We declared the variable myfile
to open a file named test.txt
. Open takes 2 arguments, the file that we want to open and a string that represents the kinds of permission or operation we want to do on the file
here is file mode options
Mode Description 'r' This is the default mode. It Opens file for reading. 'w' This Mode Opens file for writing. If file does not exist, it creates a new file. If file exists it truncates the file. 'x' Creates a new file. If file already exists, the operation fails. 'a' Open file in append mode. If file does not exist, it creates a new file. 't' This is the default mode. It opens in text mode. 'b' This opens in binary mode. '+' This will open a file for reading and writing (updating)
If you want the button to stay static without the "pressed" appearance:
// Swift 2
editButton.userInteractionEnabled = false
// Swift 3
editButton.isUserInteractionEnabled = false
Remember:
1) Your IBOutlet
is --> @IBOutlet weak var editButton: UIButton!
2) Code above goes in viewWillAppear
You'll have to use the ChannelFactory class.
Here's an example:
var myBinding = new BasicHttpBinding();
var myEndpoint = new EndpointAddress("http://localhost/myservice");
using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint))
{
IMyService client = null;
try
{
client = myChannelFactory.CreateChannel();
client.MyServiceOperation();
((ICommunicationObject)client).Close();
myChannelFactory.Close();
}
catch
{
(client as ICommunicationObject)?.Abort();
}
}

array.join
was not recognizing ";" how a separator, but replacing it with comma. Using jQuery, you can use $.each
to implode an array (Note that output_saved_json is the array and tmp is the string that will store the imploded array):
var tmp = "";
$.each(output_saved_json, function(index,value) {
tmp = tmp + output_saved_json[index] + ";";
});
output_saved_json = tmp.substring(0,tmp.length - 1); // remove last ";" added
I have used substring to remove last ";" added at the final without necessity.
But if you prefer, you can use instead substring
something like:
var tmp = "";
$.each(output_saved_json, function(index,value) {
tmp = tmp + output_saved_json[index];
if((index + 1) != output_saved_json.length) {
tmp = tmp + ";";
}
});
output_saved_json = tmp;
I think this last solution is more slower than the 1st one because it needs to check if index is different than the lenght of array every time while $.each
do not end.

There are two ways to do it: creating filter condition 1) Manually 2) Dynamically.
Sample DataFrame:
val df = spark.createDataFrame(Seq(
(0, "a1", "b1", "c1", "d1"),
(1, "a2", "b2", "c2", "d2"),
(2, "a3", "b3", null, "d3"),
(3, "a4", null, "c4", "d4"),
(4, null, "b5", "c5", "d5")
)).toDF("id", "col1", "col2", "col3", "col4")
+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
| 0| a1| b1| c1| d1|
| 1| a2| b2| c2| d2|
| 2| a3| b3|null| d3|
| 3| a4|null| c4| d4|
| 4|null| b5| c5| d5|
+---+----+----+----+----+
1) Creating filter condition manually i.e. using DataFrame where
or filter
function
df.filter(col("col1").isNotNull && col("col2").isNotNull).show
or
df.where("col1 is not null and col2 is not null").show
Result:
+---+----+----+----+----+
| id|col1|col2|col3|col4|

2) Creating filter condition dynamically: This is useful when we don't want any column to have null value and there are large number of columns, which is mostly the case.
To create the filter condition manually in these cases will waste a lot of time. In below code we are including all columns dynamically using map
and reduce
function on DataFrame columns:
val filterCond = df.columns.map(x=>col(x).isNotNull).reduce(_ && _)
How filterCond
looks:
filterCond: org.apache.spark.sql.Column = (((((id IS NOT NULL) AND (col1 IS NOT NULL)) AND (col2 IS NOT NULL)) AND (col3 IS NOT NULL)) AND (col4 IS NOT NULL))
Filtering:
val filteredDf = df.filter(filterCond)
Result:
+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
| 0| a1| b1| c1| d1|
| 1| a2| b2| c2| d2|
+---+----+----+----+----+
x ~= 0 or 1
is the same as ((x ~= 0) or 1)
x ~=(0 or 1)
is the same as (x ~= 0)
.
try something like this instead.
function isNot0Or1(x)
return (x ~= 0 and x ~= 1)
end
print( isNot0Or1(-1) == true )
print( isNot0Or1(0) == false )
print( isNot0Or1(1) == false )
Use extension methods. Replace NameOfContext with the name of your object context.
public static class Extensions{
public static IQueryable<Company> CompleteCompanies(this NameOfContext context){
return context.Companies
.Include("Employee.Employee_Car")
.Include("Employee.Employee_Country") ;
}
public static Company CompanyById(this NameOfContext context, int companyID){
return context.Companies
.Include("Employee.Employee_Car")
.Include("Employee.Employee_Country")
.FirstOrDefault(c => c.Id == companyID) ;
}
}
Then your code becomes
Company company =
context.CompleteCompanies().FirstOrDefault(c => c.Id == companyID);
//or if you want even more
Company company =
context.CompanyById(companyID);
Just a minor modification to the excellent answer above by Lessan Vaezi. I ran into a situation where I needed to include attributes in my option entries. The original implementation loses any tag attributes. This version of the above answer preserves the option tag attributes:
jQuery.fn.filterByText = function(textbox) {
return this.each(function() {
var select = this;
var options = [];
$(select).find('option').each(function() {
options.push({
value: $(this).val(),
text: $(this).text(),
attrs: this.attributes, // Preserve attributes.
});
});
$(select).data('options', options);
$(textbox).bind('change keyup', function() {
var options = $(select).empty().data('options');
var search = $.trim($(this).val());
var regex = new RegExp(search, "gi");
$.each(options, function(i) {
var option = options[i];
if (option.text.match(regex) !== null) {
var new_option = $('<option>').text(option.text).val(option.value);
if (option.attrs) // Add old element options to new entry
{
$.each(option.attrs, function () {
$(new_option).attr(this.name, this.value);
});
}
$(select).append(new_option);
}
});
});
});
};
try this trick
div{
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
this will force the browser to calculate the width acording to the "outer"-width of the div, it means the padding will be substracted from the width.
In a multi-select option box, you can use $('#input1 :selected').length;
to get the number of selected options. This can be useful to disable buttons if a certain minimum number of options aren't met.
function refreshButtons () {
if ($('#input :selected').length == 0)
{
$('#submit').attr ('disabled', 'disabled');
}
else
{
$('#submit').removeAttr ('disabled');
}
}
Just double click on the break and it will collaspe. However, it will still display the line where it will break but it's better than downloading add-ons etc.
there is a nicer alternative - use query() method:
In [58]: df = pd.DataFrame({'closing_price': np.random.randint(95, 105, 10)})
In [59]: df
Out[59]:
closing_price
0 104
1 99
2 98
3 95
4 103
5 101
6 101
7 99
8 95
9 96
In [60]: df.query('99 <= closing_price <= 101')
Out[60]:
closing_price
1 99
5 101
6 101
7 99
UPDATE: answering the comment:
I like the syntax here but fell down when trying to combine with expresison;
df.query('(mean + 2 *sd) <= closing_price <=(mean + 2 *sd)')
In [161]: qry = "(closing_price.mean() - 2*closing_price.std())" +\
...: " <= closing_price <= " + \
...: "(closing_price.mean() + 2*closing_price.std())"
...:
In [162]: df.query(qry)
Out[162]:
closing_price
0 97
1 101
2 97
3 95
4 100
5 99
6 100
7 101
8 99

It seems like what you've done is imported the socket
module as import socket
. Therefore socket
is the module. You either need to change that line to self.serv = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
, as well as every other use of the socket
module, or change the import statement to from socket import socket
.
Or you've got an import socket
after your from socket import *
:
>>> from socket import *
>>> serv = socket(AF_INET,SOCK_STREAM)
>>> import socket
>>> serv = socket(AF_INET,SOCK_STREAM)
Traceback (most recent call last):
File "<input>", line 1, in <module>

Although the selected answer is correct, I just want to further elaborate it. I found here a useful Custom Adapter for multiple View Types in RecyclerView. Its Kotlin version is here.
Custom Adapter is following
public class CustomAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private final Context context;
ArrayList<String> list; // ArrayList of your Data Model
final int VIEW_TYPE_ONE = 1;
final int VIEW_TYPE_TWO = 2;
public CustomAdapter(Context context, ArrayList<String> list) { // you can pass other parameters in constructor
this.context = context;
this.list = list;
}
private class ViewHolder1 extends RecyclerView.ViewHolder {
TextView yourView;
ViewHolder1(final View itemView) {
super(itemView);
yourView = itemView.findViewById(R.id.yourView); // Initialize your All views prensent in list items
}
void bind(int position) {
// This method will be called anytime a list item is created or update its data
//Do your stuff here
yourView.setText(list.get(position));
}
}
private class ViewHolder2 extends RecyclerView.ViewHolder {
TextView yourView;
ViewHolder2(final View itemView) {
super(itemView);
yourView = itemView.findViewById(R.id.yourView); // Initialize your All views prensent in list items
}
void bind(int position) {
// This method will be called anytime a list item is created or update its data
//Do your stuff here
yourView.setText(list.get(position));
}
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == VIEW_TYPE_ONE) {
return new ViewHolder1(LayoutInflater.from(context).inflate(R.layout.your_list_item_1, parent, false));
}
//if its not VIEW_TYPE_ONE then its VIEW_TYPE_TWO
return new ViewHolder2(LayoutInflater.from(context).inflate(R.layout.your_list_item_2, parent, false));
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (list.get(position).type == Something) { // put your condition, according to your requirements
((ViewHolder1) holder).bind(position);
} else {
((ViewHolder2) holder).bind(position);
}
}
@Override
public int getItemCount() {
return list.size();
}
@Override
public int getItemViewType(int position) {
// here you can get decide from your model's ArrayList, which type of view you need to load. Like
if (list.get(position).type == Something) { // put your condition, according to your requirements
return VIEW_TYPE_ONE;
}
return VIEW_TYPE_TWO;
}
}
For a (left outer) join of a table Bar
with a table Foo
on Foo.Foo_Id = Bar.Foo_Id
in lambda notation:
var qry = Foo.GroupJoin(
Bar,
foo => foo.Foo_Id,
bar => bar.Foo_Id,
(x,y) => new { Foo = x, Bars = y })
.SelectMany(
x => x.Bars.DefaultIfEmpty(),
(x,y) => new { Foo=x.Foo, Bar=y});
You need convert list
to numpy array
and then reshape
:
df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
a b c
0 1 2 3
1 4 5 6
2 7 8 9
Add class text-center
to your column:
<div class="col text-center">

A different take on authentication is Passwordless, a token-based authentication module for express that circumvents the inherent problem of passwords [1]. It's fast to implement, doesn't require too many forms, and offers better security for the average user (full disclosure: I'm the author).
Converting the String to JsonNode using ObjectMapper object :
ObjectMapper mapper = new ObjectMapper();
// For text string
JsonNode = mapper.readValue(mapper.writeValueAsString("Text-string"), JsonNode.class)
// For Array String
JsonNode = mapper.readValue("[\"Text-Array\"]"), JsonNode.class)
// For Json String
String json = "{\"id\" : \"1\"}";
ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = mapper.getFactory();
JsonParser jsonParser = factory.createParser(json);
JsonNode node = mapper.readTree(jsonParser);

In reply to Is there a specific reason?
, here is one interesting application: breaking out of multiple levels of looping.
Here is how it works: the outer loop has a break at the end, so it would only be executed once. However, if the inner loop completes (finds no divisor), then it reaches the else statement and the outer break is never reached. This way, a break in the inner loop will break out of both loops, rather than just one.
for k in [2, 3, 5, 7, 11, 13, 17, 25]:
for m in range(2, 10):
if k == m:
continue
print 'trying %s %% %s' % (k, m)
if k % m == 0:
print 'found a divisor: %d %% %d; breaking out of loop' % (k, m)
break
else:
continue
print 'breaking another level of loop'
break
else:
print 'no divisor could be found!'
For both while
and for
loops, the else
statement is executed at the end, unless break
was used.
In most cases there are better ways to do this (wrapping it into a function or raising an exception), but this works!
Adding the following two lines at the top of my .py script worked for me (first line was necessary):
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import pandas as pd
header=['a','b','v']
df=pd.DataFrame(columns=header)
for i in range(len(doc_list)):
d_id=(test_data.filenames[i]).split('\\')
doc_id.append(d_id[len(d_id)-1])
df['a']=doc_id
print(df.head())
df[column_names_to_be_updated]=np.asanyarray(data)
print(df.head())
df.to_csv('output.csv')
Using pandas dataframe,we can write to csv. First create a dataframe as per the your needs for storing in csv. Then create csv of the dataframe using pd.DataFrame.to_csv() API.
For adding a new column to an existing CSV file(with headers), if the column to be added has small enough number of values, here is a convenient function (somewhat similar to @joaquin's solution). The function takes the
def add_col_to_csv(csvfile,fileout,new_list):
with open(csvfile, 'r') as read_f, \
open(fileout, 'w', newline='') as write_f:
csv_reader = csv.reader(read_f)
csv_writer = csv.writer(write_f)
i = 0
for row in csv_reader:
row.append(new_list[i])
csv_writer.writerow(row)
i += 1
Example:
new_list1 = ['test_hdr',4,4,5,5,9,9,9]
add_col_to_csv('exists.csv','new-output.csv',new_list1)
For many years I used the command:
ps aux | grep postgres
On one hand it is useful (for any process) and gives useful info (but from process POV). But on the other hand it is for checking if the server you know, you already installed is running.
At some point I found this tutorial, where the usage of the locate command is shown. It looks like this command is much more to the point for this case.
You can do this programmatically using a VBA macro. You can make the sheet hidden or very hidden:
Sub HideSheet()
Dim sheet As Worksheet
Set sheet = ActiveSheet
' this hides the sheet but users will be able
' to unhide it using the Excel UI
sheet.Visible = xlSheetHidden
' this hides the sheet so that it can only be made visible using VBA
sheet.Visible = xlSheetVeryHidden
End Sub

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany
which explains how to do this with a @JoinColumn
annotation. In your case, i think you would want:
@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;
I've used a Set
rather than a List
, because the data itself is not ordered.
The above is using a defaulted referencedColumnName
, unlike the example in the wikibook. If that doesn't work, try an explicit one:
@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;
Alternative way to check would be:
if (!$('#myModal').is(':visible')) {
// if modal is not shown/visible then do something
}
capitalize the first letter of Only
input[readOnly] {_x000D_
background: red !important;_x000D_
}
_x000D_
<input type="text" name="country" value="China" readonly="readonly" />
_x000D_
using position:fixed
alone is just fine when you don't have a header or logo at the top of your page. This solution will take into account the how far the window has scrolled, and moves the div when you scrolled past your header. It will then lock it back into place when you get to the top again.
if($(window).scrollTop() > Height_of_Header){
//begin to scroll
$("#div").css("position","fixed");
$("#div").css("top",0);
}
else{
//lock it back into place
$("#div").css("position","relative");
}
If you're using Jquery to manipulate the DOM, then I have found the following a good way to include logic in a Jquery statement:
$(selector).addClass(A && B?'classIfTrue':'');
class Person:
def init(self,name,age,weight,sex,mob_no,place):
self.name = str(name)
self.age = int(age)
self.weight = int(weight)
self.sex = str(sex)
self.mob_no = int(mob_no)
self.place = str(place)
p1 = Person(Muthuswamy,50,70,Male,94*****23,India)
print(p1.name)
print(p1.place)
Muthuswamy

Similar to Lloyd's answer, but works with any size array.
$missing = array();
$missing[] = 'name';
$missing[] = 'zipcode';
$missing[] = 'phone';
if( is_array($missing) && count($missing) > 0 )
{
$result = '';
$total = count($missing) - 1;
for($i = 0; $i <= $total; $i++)
{
if($i == $total && $total > 0)
$result .= "and ";
$result .= $missing[$i];
if($i < $total)
$result .= ", ";
}
echo 'You need to provide your '.$result.'.';
// Echos "You need to provide your name, zipcode, and phone."
}
You can index dataframe columns by the position using ix
.
df1.ix[:,1]
This returns the first column for example. (0 would be the index)
df1.ix[0,]
This returns the first row.
df1.ix[:,1]
This would be the value at the intersection of row 0 and column 1:
df1.ix[0,1]
and so on. So you can enumerate()
returns.keys():
and use the number to index the dataframe.

Let us see a more updated approach to this question:
Import AudioToolbox
func noteSelector(noteNumber: String) {
if let soundURL = Bundle.main.url(forResource: noteNumber, withExtension: "wav") {
var mySound: SystemSoundID = 0
AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
AudioServicesPlaySystemSound(mySound)
}
Function imageMorph
will create a new img element therefore the id is removed.
Changed to
$("#wrapper > img")

Probably the shortest solution:
def printLog(*args, **kwargs):
print(*args, **kwargs)
with open('output.out','a') as file:
print(*args, **kwargs, file=file)
printLog('hello world')
Writes 'hello world' to sys.stdout
and to output.out
and works exactly the same way as print().
Note:
Please do not specify the file argument for the printLog function. Calls like printLog('test',file='output2.out')
are not supported.
The CORS spec is all-or-nothing. It only supports *
, null
or the exact protocol + domain + port: http://www.w3.org/TR/cors/#access-control-allow-origin-response-header
Your server will need to validate the origin header using the regex, and then you can echo the origin value in the Access-Control-Allow-Origin
response header.
An alternative to the cursor.description solution from smallredstone could be to use row.keys():
import sqlite3
connection = sqlite3.connect('~/foo.sqlite')
connection.row_factory = sqlite3.Row
cursor = connection.execute('select * from bar')
# instead of cursor.description:
row = cursor.fetchone()
names = row.keys()
The drawback: it only works if there is at least a row returned from the query.
The benefit: you can access the columns by their name (row['your_column_name'])
Read more about the Row objects in the python documentation.
You can get the spark version by using the following command:

You can visit the below site to know the spark-version used in CDH 5.7.0
Please check if you have already close the database connection or not. In my case i was getting the error because the connection was close in upper line.
You can use zip
with *
to get transpose of a matrix:
>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis = [[1,2,3],
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]
If you want the returned list to be a list of lists:
>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))

JSONP is the best option, in my opinion. Try to figure out why you get the syntax error - are you sure the received data is not JSON? Then maybe you're using the API wrong somehow.
Another way you could use, but I don't think that it applies in your case, is have an iFrame in the page which src is in the domain you want to call. Have it do the calls for you, and then use JS to communicate between the iFrame and the page. This will bypass the cross domain, but only if you can have the iFrame's src in the domain you want to call.
You should use readfile()
:
readfile("/path/to/file");
This will read the file and send it to the browser in one command. This is essentially the same as:
echo file_get_contents("/path/to/file");
except that file_get_contents()
may cause the script to crash for large files, while readfile()
won't.
# Hide grid lines
ax.grid(False)
# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])
Note, you need matplotlib>=1.2 for set_zticks()
to work.

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.
EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character
If that next lines never contain 'blah', you can filter them with:
grep -A1 blah logfile | grep -v blah
The use of cat logfile | ...
is not needed.
If you need a free and simple API for converting one currency to another, try free.currencyconverterapi.com.
Disclaimer, I'm the author of the website and I use it for one of my other websites.
The service is free to use even for commercial applications but offers no warranty. For performance reasons, the values are only updated every hour.
A sample conversion URL is: http://free.currencyconverterapi.com/api/v6/convert?q=EUR_PHP&compact=ultra&apiKey=sample-api-key which will return a json-formatted value, e.g. {"EUR_PHP":60.849184}
According the documentaion hide / toggle should work. But it don't.
Here is how I did it
$('#modal-id').modal('toggle'); //Hide the modal dialog
$('.modal-backdrop').remove(); //Hide the backdrop
$("body").removeClass( "modal-open" ); //Put scroll back on the Body
This should work:
$("label[for='comedyclubs']")

you may have to use div instead of li for that
.DivParent {_x000D_
height: 100px;_x000D_

After 7 long hours of searching I finally found the way!! None of the above solutions worked, only one of them pointed towards the issue!
If you are on Win7, then your Firewall blocks the SDK Manager from retrieving the addon list. You will have to add "android.bat" and "java.exe" to the trusted files and bingo! everything will start working!!
items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:
you can also get the line if there are other characters before token
items=re.findall("^.*token.*$",s,re.MULTILINE)
The above works like grep token on unix and keyword 'in' or .contains in python and C#
s='''
qwertyuiop
asdfghjkl
zxcvbnm
token qwerty
asdfghjklñ
'''
http://pythex.org/ matches the following 2 lines
....
....
token qwerty
it's right way to use operator overloading now you get your object by reference avoiding value copying.
I posted this in another question, but I find using tables with iTextSharp offers a great level of precision.
document.Add(BlankLineDoc(16));
public static PdfPTable BlankLineDoc(int height)
{
var table = new PdfPTable(1) {WidthPercentage = 100};
table = BlankLineTable(table, height);
return table;
}
public static PdfPTable BlankLineTable(PdfPTable table, int height, int border = Rectangle.NO_BORDER)
{
var cell = new PdfPCell(new Phrase(" "))
{
Border = border,
Colspan = table.NumberOfColumns,
FixedHeight = height
};
table.AddCell(cell);
return table;
}
BlankLineTable can be used directly when working with tables
Works for me:

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".
Sub test()
dbWb = Application.ActiveWorkbook.FullName
dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2" 'Data2 is a named range
sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh
Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command
dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon
dbCommand.CommandText = sCommand
dbCommand.Execute
dbCon.Close
End Sub
The Most simple code you can write:
persons.stream().map(x-> x.getName()).distinct().collect(Collectors.toList());
use this actiion
$(document).ready(function () {
var a = this.id;
alert (a);
});
Use Modernizr for detection of feature capabilities. In general jQuery offers to detect browser features: http://api.jquery.com/jQuery.support/. However, hashchange is not on the list.
The wiki of Modernizr offers a list of libraries to add HTML5 capabilities to old browsers. The list for hashchange includes a pointer to the project HTML5 History API, which seems to offer the functionality you would need if you wanted to emulate the behavior in old browsers.
Short variant:
my_var = some_value if 'my_var' not in globals() else my_var:
here is an example i did on change i get children of the first select in second select
jQuery(document).ready(function($) {
$('.your_select').change(function() {
$.ajaxSetup({
headers:{'X-CSRF-TOKEN': $("meta[name='csrf-token']").attr('content')}
});
$.ajax({
type:'POST',
url: 'Link',
data:{
'id': $(this).val()
},
success:function(r){
$.each(r, function(res) {
console.log(r[res].Nom);
$('.select_to_populate').append($("<option />").val(r[res].id).text(r[res].Nom));
});
},error:function(r) {
alert('Error');
}
});
});

I have a proper solution of this problem, lets try and understand the root cause of this issue. This issue comes when remote servers ssl cannot be verified using root certificates in your system's certificate store or remote ssl is not installed along with chain certificates. If you have a linux system with root ssh access, then in this case you can try updating your certificate store with below command:
update-ca-certificates
If still, it doesn't work then you need to add root and interim certificate of remote server in your cert store. You can download root and intermediate certs and add them in /usr/local/share/ca-certificates directory and then run command update-ca-certificates
. This should do the trick. Similarly for windows you can search how to add root and intermediate cert.
The other way you can solve this problem is by asking remote server team to add ssl certificate as a bundle of domain root cert, intermediate cert and root cert.
We can use the below Methods to get the version Number of Oracle.
Method No : 1
set serveroutput on;
BEGIN
DBMS_OUTPUT.PUT_LINE(DBMS_DB_VERSION.VERSION || '.' || DBMS_DB_VERSION.RELEASE);
END;
Method No : 2

2 from v$version;
Unfortunately, neither of answers are good for me. Surprisingly the solution is much simpler. Return from controller:
return new HttpStatusCodeResult(HttpStatusCode.BadRequest, e.Response.ReasonPhrase);
And handle it as standard HTTP error on client as you like.
First of all, do you really need to store indices like this? Have you looked into std::map, enabling you to store key => value pairs?
Secondly, if you used iterators instead, you would be able to return std::vector.end() to indicate an invalid result. To convert an iterator to an index you simply use
size_t i = it - myvector.begin();
I recently had same issue with Spring 4.0.
It was caused by a collision in names from spring-beans-4.0.xsd
and spring-context-4.0.xsd
.
Opening spring-context-4.0.xsd
you can see that spring-beans-4.0.xsd
is imported like follow:
<xsd:import namespace="http://www.springframework.org/schema/beans"
schemaLocation="http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"/>
These name's collisions make Eclipse complain about "...A schema cannot contain two global components with the same name..."
A noteworthy aspect is that I hadn't this problem with Eclipse Kepler SR2 but Eclipse Luna SR1, comparing both preferences about XML Validation, they were the same.
It was solved by removing spring-context-4.0.xsd from xsi:schemaLocation attribute:
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
After this everything worked as expected.
Here's a dead simple usage of multiprocessing.Queue
and multiprocessing.Process
that allows callers to send an "event" plus arguments to a separate process that dispatches the event to a "do_" method on the process. (Python 3.4+)
import multiprocessing as mp
import collections
Msg = collections.namedtuple('Msg', ['event', 'args'])
class BaseProcess(mp.Process):
"""A process backed by an internal queue for simple one-way message passing.
"""
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.queue = mp.Queue()
def send(self, event, *args):
"""Puts the event and args as a `Msg` on the queue
"""
msg = Msg(event, args)
self.queue.put(msg)
def dispatch(self, msg):
event, args = msg
handler = getattr(self, "do_%s" % event, None)
if not handler:
raise NotImplementedError("Process has no handler for [%s]" % event)
handler(*args)
def run(self):
while True:
msg = self.queue.get()
self.dispatch(msg)
Usage:
class MyProcess(BaseProcess):
def do_helloworld(self, arg1, arg2):
print(arg1, arg2)
if __name__ == "__main__":
process = MyProcess()
process.start()
process.send('helloworld', 'hello', 'world')
The send
happens in the parent process, the do_*
happens in the child process.
I left out any exception handling that would obviously interrupt the run loop and exit the child process. You can also customize it by overriding run
to control blocking or whatever else.
This is really only useful in situations where you have a single worker process, but I think it's a relevant answer to this question to demonstrate a common scenario with a little more object-orientation.
You can make use of cut
, sort
and uniq
commands as follows:
cat input_file | cut -f 1 | sort | uniq
gets unique values in field 1, replacing 1 by 2 will give you unique values in field 2.
Avoiding UUOC :)
cut -f 1 input_file | sort | uniq
EDIT:
To count the number of unique occurences you can make use of wc
command in the chain as:
cut -f 1 input_file | sort | uniq | wc -l
select CustomerName,count(1) from Customers group by CustomerName having count(1) > 1
I recently had the same problem and used the solution provided by Harry Joy. That solution only works with with zero-based enumaration though. I also wouldn't consider it save as it doesn't deal with indexes that are out of range.
The solution I ended up using might not be as simple but it's completely save and won't hurt the performance of your code even with big enums:
public enum Example {
UNKNOWN(0, "unknown"), ENUM1(1, "enum1"), ENUM2(2, "enum2"), ENUM3(3, "enum3");
private static HashMap<Integer, Example> enumById = new HashMap<>();
static {
Arrays.stream(values()).forEach(e -> enumById.put(e.getId(), e));
}
public static Example getById(int id) {
return enumById.getOrDefault(id, UNKNOWN);
}
private int id;
private String description;
private Example(int id, String description) {
this.id = id;
this.description= description;
}
public String getDescription() {
return description;
}
public int getId() {
return id;
}
}
If you are sure that you will never be out of range with your index and you don't want to use UNKNOWN
like I did above you can of course also do:
public static Example getById(int id) {
return enumById.get(id);
}

So, the concept of a "wildcard" in Regular Expressions works a bit differently. In order to match "any character" you would use "." The "*" modifier means, match any number of times.
Here's how I addressed this (using a MEAN derivative)
My variables:
{
NODE_ENV : development,
...
ui_varables {
var1: one,
var2: two
}
}
First I had to make sure that the necessary config variables were being passed. MEAN uses the node nconf package, and by default is set up to limit which variables get passed from the environment. I had to remedy that:
config/config.js:
original:
nconf.argv()
.env(['PORT', 'NODE_ENV', 'FORCE_DB_SYNC'] ) // Load only these environment variables
.defaults({
store: {
NODE_ENV: 'development'
}
});
after modifications:
nconf.argv()
.env('__') // Load ALL environment variables
// double-underscore replaces : as a way to denote hierarchy
.defaults({
store: {
NODE_ENV: 'development'
}
});
Now I can set my variables like this:
export ui_varables__var1=first-value
export ui_varables__var2=second-value
Note: I reset the "heirarchy indicator" to "__" (double underscore) because its default was ":", which makes variables more difficult to set from bash. See another post on this thread.
Now the jade part: Next the values need to be rendered, so that javascript can pick them up on the client side. A straightforward way to write these values to the index file. Because this is a one-page app (angular), this page is always loaded first. I think ideally this should be a javascript include file (just to keep things clean), but this is good for a demo.
app/controllers/index.js:
'use strict';
var config = require('../../config/config');
exports.render = function(req, res) {
res.render('index', {
user: req.user ? JSON.stringify(req.user) : "null",
//new lines follow:
config_defaults : {
ui_defaults: JSON.stringify(config.configwriter_ui).replace(/<\//g, '<\\/') //NOTE: the replace is xss prevention
}
});
};
app/views/index.jade:
extends layouts/default
block content
section(ui-view)
script(type="text/javascript").
window.user = !{user};
//new line here
defaults = !{config_defaults.ui_defaults};
In my rendered html, this gives me a nice little script:
<script type="text/javascript">
window.user = null;
defaults = {"var1":"first-value","var2:"second-value"};
</script>
From this point it's easy for angular to utilize the code.
You Just need to subtract one day from today's date. In Python datetime.timedelta
object lets you create specific spans of time as a timedelta
object.
datetime.timedelta(1)
gives you the duration of "one day" and is subtractable from a datetime
object. After you subtracted the objects you can use datetime.strftime
in order to convert the result --which is a date object-- to string format based on your format of choice:
>>> from datetime import datetime, timedelta
>>> yesterday = datetime.now() - timedelta(1)
>>> type(yesterday)
>>> datetime.datetime
>>> datetime.strftime(yesterday, '%Y-%m-%d')
'2015-05-26'
Note that instead of calling the datetime.strftime
function, you can also directly use strftime
method of datetime
objects:
>>> (datetime.now() - timedelta(1)).strftime('%Y-%m-%d')
'2015-05-26'
As a function:
def yesterday(string=False):
yesterday = datetime.now() - timedelta(1)
if string:
return yesterday.strftime('%Y-%m-%d')
return yesterday
If you want to retain the last one of the duplicates you could use
tac a.csv | sort -u -t, -r -k1,1 |tac
Which was my requirement
here
tac
will reverse the file line by line
Erland Sommarskog has maintained the authoritative answer to this question for the last 16 years: Arrays and Lists in SQL Server.
There are at least a dozen ways to pass an array or list to a query; each has their own unique pros and cons.
I really can't recommend enough to read the article to learn about the tradeoffs among all these options.
You can see a detailed description here.
ini_set('display_errors', 1);
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
// Report all PHP errors
error_reporting(-1);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

TextMate with the Django and django-html bundles installed gives you syntax highlighting and great extensibility. It is lightweight and fun to use.
Here is a link to a code completion project for TextMate with Python (which I haven't used myself). As for "intellisense" (which I understand to be inline-doc reference), TextMate has that too.
The direct answer is that you can't. You must select either an aggregate or something that you are grouping by.
So, you need an alternative approach.
1). Take you current query and join the base data back on it
SELECT
cpe.*
FROM
Filteredfmgcms_claimpaymentestimate cpe
INNER JOIN
(yourQuery) AS lookup
ON lookup.MaxData = cpe.createdOn
AND lookup.fmgcms_cpeclaimid = cpe.fmgcms_cpeclaimid
2). Use a CTE to do it all in one go...
WITH
sequenced_data AS
(
SELECT
*,
ROW_NUMBER() OVER (PARITION BY fmgcms_cpeclaimid ORDER BY CreatedOn DESC) AS sequence_id
FROM
Filteredfmgcms_claimpaymentestimate
WHERE
createdon < 'reportstartdate'
)
SELECT
*
FROM
sequenced_data
WHERE
sequence_id = 1
NOTE: Using ROW_NUMBER()
will ensure just one record per fmgcms_cpeclaimid
. Even if multiple records are tied with the exact same createdon
value. If you can have ties, and want all records with the same createdon
value, use RANK()
instead.
If you check Thrown
for Common Language Runtime Exception
in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.
This will probably give you some insight into what is going on.
I am currently working on phpDataMapper, which is an ORM designed to have simple syntax like Ruby's Datamapper project. It's still in early development as well, but it works great.
