A framework helps us about using the "already created", a metaphore can be like,
think that earth material is the programming language,
and for example "a camera" is the program, and you decided to create a notebook. You don't need to recreate the camera everytime, you just use the earth framework (for example to a technology store) take the camera and integrate it to your notebook.
Play is pretty sweet.
It is now production ready. It incorporates: a cool template framework,automatic reloading of source files upon safe, a composable action system, akka awesomeness, etc.
Its part of the Typesafe Stack.
Having used it for two projects, I can say that it works pretty smoothly and it should be something to consider next time you are looking to learn new web frameworks.
In the project navigator, select your project.
Select your target.
Select the "Build Phases" tab.
expander. Click the + button.
Select your framework.
(optional) Drag and drop the added framework to the "Frameworks" group.
I forget where I saw this definition, but I think it's pretty nice.
A library is a module that you call from your code, and a framework is a module which calls your code.
Got this from the Laravel forums, but if you recently upgraded Laravel versions AND PHP versions AND are running nginx, make sure you have changed your nginx configuration file to reflect the new PHP version. For instance:
In your nginx site config file (here: /etc/nginx/sites-available), change
fastcgi_pass unix:/var/run/php5-fpm.sock;
to
fastcgi_pass unix:/var/run/php/php5.6-fpm.sock;
Look at an HTML parser such as TagSoup, HTMLCleaner or NekoHTML.
Old days, Spring was a dependency injection frame work only like (Guice, PicoContainer,...), but nowadays it is a total solution for building your Enterprise Application.
The spring dependency injection, which is, of course, the heart of spring is still there (and you can review other good answers here), but there are more from spring...
Spring now has lots of projects, each with some sub-projects (http://spring.io/projects). When someone speaks about spring, you must find out what spring project he is talking about, is it only spring core, which is known as spring framework, or it is another spring projects.
Some spring projects which is worth too mention are:
If you need some more specify feature for your application, you may find it there too:
There are also some tiny projects there for example spring-social-facebook (http://projects.spring.io/spring-social-facebook/)
You can use spring for web development as it has the Spring MVC
module which is part of Spring Framework project. Or you can use spring with another web framework, like struts2.
Middleware is a general term for software that serves to "glue together" separate, often complex and already existing, programs. Some software components that are frequently connected with middleware include enterprise applications and Web services.
Go to Netcraft and use the "What's that site running?" search box in the top left corner. Click here for the report on Stack Overflow. It won't necessarily be correct (e.g., there could be caching or load balancing in the way), but it often gives you the clue you need.
Using Commons Lang (to convert) + Collections (to min/max)
import java.util.Arrays;
import java.util.Collections;
import org.apache.commons.lang.ArrayUtils;
public class MinMaxValue {
public static void main(String[] args) {
char[] a = {'3', '5', '1', '4', '2'};
List b = Arrays.asList(ArrayUtils.toObject(a));
System.out.println(Collections.min(b));
System.out.println(Collections.max(b));
}
}
Note that Arrays.asList()
wraps the underlying array, so it should not be too memory intensive and it should not perform a copy on the elements of the array.
It was quite simple for me, i just added my framework to my embedded binaries under app targets
Yii::app()->request->url
Yii::$app->request->url
I answered too late but it has worked in my case.If you are facing this issue in your project please add the following line in your web.config :
<compilation batch="false" >
This worked in my case. If you already have compilation tag in your web.config then add only batch="false" property to it.
If you want to get the root directory of your yii2 project use, assuming that the name of your project is project_app you'll need to use:
echo Yii::getAlias('@app');
on windows you'd see "C:\dir\to\project_app"
on linux you'll get "/var/www/dir/to/your/project_app"
I was formally using:
echo Yii::getAlias('@webroot').'/..';
I hope this helps someone
Difference between Spring, Struts and Hibernate are following:
SDK represents to software development kit, and IDE represents to integrated development environment. The IDE is the software or the program is used to write, compile, run, and debug such as Xcode. The SDK is the underlying engine of the IDE, includes all the platform's libraries an app needs to access. It's more basic than an IDE because it doesn't usually have graphical tools.
We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.
Check your linker flags:
Target > Build Settings > Other Linker Flags
You should see -lApptentiveConnect
listed as a linker flag:
... -ObjC -lApptentiveConnect ...
You should also see our required Frameworks listed:

v-model
it is two way data binding, it is used to bind html input element when you change input value then bounded data will be change.
v-model is used only for HTML input elements
ex: <input type="text" v-model="name" >
v-bind
it is one way data binding,means you can only bind data to input element but can't change bounded data changing input element.
v-bind is used to bind html attribute
ex:
<input type="text" v-bind:class="abc" v-bind:value="">
<a v-bind:href="home/abc" > click me </a>
Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.
Have in mind also that,
large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.
-- Announcement of YUI development being ceased
That said, below are a number of Ext JS alternatives currently available.
Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.
Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.
Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.
Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.
The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).
The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.
Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.
kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).
Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.
A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.
The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.
The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.
Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO
DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.
Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.
Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.
Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).
The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.
PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.
qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).
Mobile themes look modern but desktop themes look old (gradients).

jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.
angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).
DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.
Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.
Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.
With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.
Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.
The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM
Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.
CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.
ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.
Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.
CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.
Widgets - Demo Apps - Examples - GitHub
SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.
Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:
Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile
Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.
Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.
SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.
Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework
Backbase - portal software
Shiny - front-end library on top R, with visualization, layout and control widgets
ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.
These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.
Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library
UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.
Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.
Regardless of where you put the CSS file you can simply use the CodeIgniter "html" helper called link_tag(). You would apply this helper something like this:
echo link_tag('folder/subfolder/stylesheet.css');
It is up to you to locate the CSS file in the most appropriate place (in your opinion). You would have to either autoload the "html" helper or separately load it in to use it.
People keep suggesting the usage of base_url() to achieve this but it is actually not really the "CodeIgniter" way to do it (I think this question has a few duplicates). That will work but one of the reasons for using a framework is to use the pre-made functions within it.
There are many helpers in codeigniter to do this kind of thing.
I strongly recommend TurboGears or Bottle:
TurboGears:
Bottle:
Put your assets in the public folder
public/css
public/images
public/fonts
public/js
And then called it using Laravel
{{ URL::asset('js/scrollTo.js'); }} // Generates the path to public directory public/js/scrollTo.js
{{ URL::asset('css/css.css'); }} // Generates the path to public directory public/css/css.css
(OR)
{{ HTML::script('js/scrollTo.js'); }} // Generates the path to public directory public/js/scrollTo.js
{{ HTML::style('css/css.css'); }} // Generates the path to public directory public/css/css.css
Or simply use
ng-show="v.hasOwnProperty('secId')"

None is used to indicate "not set", whereas any other value is used to indicate a "default" value.
Hence, if your class copes with empty strings and you like it as a default value, use "". If your class needs to check if the variable was set at all, use None.
Notice that it doesn't matter if your variable is a string initially. You can change it to any other type/value at any other moment.
Try using the responses library. Here is an example from their documentation:
import responses
import requests
@responses.activate
def test_simple():
responses.add(responses.GET, 'http://twitter.com/api/1/foobar',
json={'error': 'not found'}, status=404)
resp = requests.get('http://twitter.com/api/1/foobar')
assert resp.json() == {"error": "not found"}
assert len(responses.calls) == 1
assert responses.calls[0].request.url == 'http://twitter.com/api/1/foobar'
assert responses.calls[0].response.text == '{"error": "not found"}'
It provides quite a nice convenience over setting up all the mocking yourself.
There's also HTTPretty:
It's not specific to requests
library, more powerful in some ways though I found it doesn't lend itself so well to inspecting the requests that it intercepted, which responses
does quite easily
There's also httmock.
This is the simplest and easy way. This is how we do this.
var obj = { 'bar' : 'baz' }_x000D_
var key = Object.keys(obj)[0];_x000D_
var value = obj[key];_x000D_
_x000D_
console.log("key = ", key) // bar_x000D_
console.log("value = ", value) // baz
_x000D_
Object.keys(obj) // ['bar']
Now you can iterate on the objects and can access values like below-
Object.keys(obj).forEach( function(key) {
console.log(obj[key]) // baz
})
Why not grab them from dependencies
in package.json
?
Of course, this will only give you the ones you actually saved, but you should be doing that anyway.
console.log(Object.keys(require('./package.json').dependencies));
One way this can be done is using shell script in global environment section, here, I am using UNIX timestamp but you can use any shell script syntax compatible time format:
pipeline {
agent any
environment {
def BUILDVERSION = sh(script: "echo `date +%s`", returnStdout: true).trim()
}
stages {
stage("Awesome Stage") {
steps {
echo "Current build version :: $BUILDVERSION"
}
}
}
}
Don't use your raw url
Instead of:
cookieManager.setCookie(myUrl, cookieString);
use it like this:
cookieManager.setCookie("your url host", cookieString);
Perhaps you misunderstood the difference between &
and &&
, |
and ||
The purpose of the shortcut operators &&
and ||
is that the value of the first operand can determine the result and so the second operand doesn't need to be evaluated.
This is especially useful if the second operand would results in an error. e.g.
if (set == null || set.isEmpty())
// or
if (list != null && list.size() > 0)
However with XOR, you always have to evaluate the second operand to get the result so the only meaningful operation is ^
.
Single quotes will not parse PHP variables inside of them. Either use double quotes or use a dot to extend the echo.
$variableName = 'Ralph';
echo 'Hello '.$variableName.'!';
OR
echo "Hello $variableName!";
And in your case:
$i = 1;
echo '<p class="paragraph'.$i.'"></p>';
++i;
OR
$i = 1;
echo "<p class='paragraph$i'></p>";
++i;

@kindall's solution does not work with my Python version 3.5. @styles correctly states in his comment that the reason is the additional optional keywords argument. Hence my slightly refined version for Python 3 looks like this:
if VERBOSE:
def verboseprint(*args, **kwargs):
print(*args, **kwargs)
else:
verboseprint = lambda *a, **k: None # do-nothing function
In Python 2.x just put a ,
at the end of your print
statement. If you want to avoid the blank space that print
puts between items, use sys.stdout.write
.
import sys
sys.stdout.write('hi there')
sys.stdout.write('Bob here.')
yields:
hi thereBob here.
Note that there is no newline or blank space between the two strings.
In Python 3.x, with its print() function, you can just say
print('this is a string', end="")
print(' and this is on the same line')
and get:
this is a string and this is on the same line
There is also a parameter called sep
that you can set in print with Python 3.x to control how adjoining strings will be separated (or not depending on the value assigned to sep
)
E.g.,
Python 2.x
print 'hi', 'there'
gives
hi there
Python 3.x
print('hi', 'there', sep='')
gives
hithere
Given: text = "42 0"

I think the biggest confusion is that xml namespace is pointing to some kind of URL that doesn't have any information. But the truth is that the person who invented below namespace:
xmlns:android="http://schemas.android.com/apk/res/android"
could also call it like that:
xmlns:android="asjkl;fhgaslifujhaslkfjhliuqwhrqwjlrknqwljk.rho;il"
This is just a unique identifier. However it is established that you should put there URL that is unique and can potentially point to the specification of used tags/attributes in that namespace. It's not required tho.
Why it should be unique? Because namespaces purpose is to have them unique so the attribute for example called background from your namespace can be distinguished from the background from another namespace.
Because of that uniqueness you do not need to worry that if you create your custom attribute you gonna have name collision.
I think the example is wrong - javax.sql.DataSource
doesn't have these properties either. Your DataSource
needs to be of the type org.apache.derby.jdbc.ClientDataSource
, which should have those properties.
findAny
& orElse
By using findAny()
and orElse()
:
Person matchingObject = objects.stream().
filter(p -> p.email().equals("testemail")).
findAny().orElse(null);
Stops looking after finding an occurrence.
findAny
Optional<T> findAny()
Returns an Optional describing some element of the stream, or an empty Optional if the stream is empty. This is a short-circuiting terminal operation. The behavior of this operation is explicitly nondeterministic; it is free to select any element in the stream. This is to allow for maximal performance in parallel operations; the cost is that multiple invocations on the same source may not return the same result. (If a stable result is desired, use findFirst() instead.)
You need to call CLASS in button
<button class="tim" id="rock" onClick="choose(1)">Rock</button>
<style>
.tim{
font-size: 18px;
border: 2px solid #AD235E;
border-radius: 100px;

height: 150px; background-image: url(images/Sun.jpg);
}
</style>
From the fine manual:
ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;
There's no need to specify the type when you're just changing the nullability.
You may use Apache Commons IO:
try (OutputStream outputStream = ...) {
IOUtils.write("data", outputStream, "UTF-8");
}
Execute the same commands but replace the "-A" with "-D". For example:
iptables -A ...
becomes
iptables -D ...
Copies a directory named html & all its contents to a destination directory in silent mode. If the destination directory is not present it will still create it.
@echo off
TITLE Copy Folder with Contents
set SOURCE=C:\labs
set DESTINATION=C:\Users\MyUser\Desktop\html
xcopy %SOURCE%\html\* %DESTINATION%\* /s /e /i /Y >NUL
/S Copies directories and subdirectories except empty ones.
/E Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T.
/I If destination does not exist and copying more than one file, assumes that destination must be a directory.

Not sure if it helps you still... but I had to do a small trick to make the image bigger but keeping it responsive
@media screen and (max-width: 368px) {
img.smallResolution{
min-height: 150px;
}
}
Hope it helps P.S. The max width can be anything you like
You can't call "printf" with a std::string in parameter. The "%s" is designed for C-style string : char* or char []. In C++ you can do like that :
#include <iostream>
std::cout << YourString << std::endl;
If you absolutely want to use printf, you can use the "c_str()" method that give a char* representation of your string.
printf("%s\n",YourString.c_str())
try changing that line-height change to a margin-top or padding-top change instead
#btnhome:active{
margin-top : 25px;
}
Edit: You could also try adding a span inside the button
<div id="header">
<button id="btnhome"><span>Home</span></button>
<button id="btnabout">About</button>
<button id="btncontact">Contact</button>
<button id="btnsup">Help Us</button>
</div>
Then style that
#btnhome span:active { padding-top:25px;}
If you don't have any other indexes or sorted information for your objects, then you will have to iterate until such an object is found:
next(obj for obj in objs if obj.val == 5)
This is however faster than a complete list comprehension. Compare these two:
[i for i in xrange(100000) if i == 1000][0]
next(i for i in xrange(100000) if i == 1000)
The first one needs 5.75ms, the second one 58.3µs (100 times faster because the loop 100 times shorter).
I was getting the same UnicodeEncodeError
when saving scraped web content to a file. To fix it I replaced this code:
with open(fname, "w") as f:
f.write(html)
with this:
import io
with io.open(fname, "w", encoding="utf-8") as f:
f.write(html)
Using io
gives you backward compatibility with Python 2.
If you only need to support Python 3 you can use the builtin open
function instead:
with open(fname, "w", encoding="utf-8") as f:
f.write(html)
It can be done this way as well:
$('input', '#div').each(function () {
console.log($(this)); //log every element found to console output
});
If you don't want your data to be seen by the user, use a PHP session.
Data in a post request is still accessible (and manipulable) by the user.

This code extracts the YouTube video duration using the YouTube API v3 by passing a video ID. It worked for me.
<?php
function getDuration($videoID){
$apikey = "YOUR-Youtube-API-KEY"; // Like this AIcvSyBsLA8znZn-i-aPLWFrsPOlWMkEyVaXAcv
$dur = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=$videoID&key=$apikey");
$VidDuration =json_decode($dur, true);
foreach ($VidDuration['items'] as $vidTime)
{
$VidDuration= $vidTime['contentDetails']['duration'];
}
preg_match_all('/(\d+)/',$VidDuration,$parts);
return $parts[0][0] . ":" .
$parts[0][1] . ":".
$parts[0][2]; // Return 1:11:46 (i.e.) HH:MM:SS
}
echo getDuration("zyeubYQxHyY"); // Video ID
?>
You can get your domain's own YouTube API key on https://console.developers.google.com and generate credentials for your own requirement.
A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:
from tkinter import Frame, Tk
class MyApp():
def __init__(self):
self.root = Tk()
self.my_frame_red = Frame(self.root, bg='red')
self.my_frame_red.grid(row=0, column=0, sticky='nsew')
self.my_frame_blue = Frame(self.root, bg='blue')
self.my_frame_blue.grid(row=0, column=1, sticky='nsew')
self.root.grid_rowconfigure(0, minsize=200, weight=1)
self.root.grid_columnconfigure(0, minsize=200, weight=1)
self.root.grid_columnconfigure(1, weight=1)
self.root.mainloop()
if __name__ == '__main__':
app = MyApp()
But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.
You cannot concatenate a string
with an int
. You would need to convert your int
to a string
using the str
function, or use formatting
to format your output.
Change: -
print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")
to: -
print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))
or: -
print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")
or as per the comment, use ,
to pass different strings to your print
function, rather than concatenating using +
: -
print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")
Use this
DELETE FROM `articles`, `comments`
USING `articles`,`comments`
WHERE `comments`.`article_id` = `articles`.`id` AND `articles`.`id` = 4
or
DELETE `articles`, `comments`
FROM `articles`, `comments`
WHERE `comments`.`article_id` = `articles`.`id` AND `articles`.`id` = 4
You can also use this:
ALTER TABLE [tablename] CHANGE [columnName] [columnName] DECIMAL (10,2)
Your logic condition is wrong. IIUC, what you want is:
import pyspark.sql.functions as f
df.filter((f.col('d')<5))\
.filter(
((f.col('col1') != f.col('col3')) |
(f.col('col2') != f.col('col4')) & (f.col('col1') == f.col('col3')))
)\
.show()
I broke the filter()
step into 2 calls for readability, but you could equivalently do it in one line.
Output:
+----+----+----+----+---+
|col1|col2|col3|col4| d|
+----+----+----+----+---+
| A| xx| D| vv| 4|
| A| x| A| xx| 3|
| E| xxx| B| vv| 3|
| F|xxxx| F| vvv| 4|
| G| xxx| G| xx| 4|
+----+----+----+----+---+
I'll give you one nice function for this problem:
function url_redirect(url){
var X = setTimeout(function(){
window.location.replace(url);
return true;
},300);
if( window.location = url ){
clearTimeout(X);
return true;
} else {
if( window.location.href = url ){
clearTimeout(X);
return true;
}else{
clearTimeout(X);
window.location.replace(url);
return true;
}
}
return false;
};
This is universal working solution for the window.location
problem. Some browsers go into problem with window.location.href
and also sometimes can happen that window.location
fail. That's why we also use window.location.replace()
for any case and timeout for the "last try".
Try this:
HTML
<div><span>Text</span></div>
CSS
div {
height: 100px;
}
span {
height: 100px;
display: table-cell;
vertical-align: middle;
}
Here you can find a nice tutorial of how you can create and consume a SOAP service through WSDL. Long story short you need to call wsimport tool from command line (you can find it in your jdk) with parameters like -s (source for .java files) -d (destination for .class files) and the wsdl link.
$ wsimport -s "C:\workspace\soap\src\main\java\com\test\soap\ws" -d "C:\workspace\soap\target\classes\com\test\soap\ws" http://localhost:8855/soap/test?wsdl
After the stubs are created, you can call the webservices very easy something like:
TestHarnessService harnessService = new TestHarnessService();
ITestApi testApi = harnessService.getBasicHttpBindingITestApi();
testApi.resetLogMemoryTarget();
If you really want to force-download all dependencies, you can try to re-initialise the entire maven repository. Like in this article already described, you could use:
mvn -Dmaven.repo.local=$HOME/.my/other/repository clean install
<?php
$connection =mysql_connect("localhost", "root" , "");
$sqlimage = "SELECT * FROM userdetail where `id` = '".$id1."'";
$imageresult1 = mysql_query($sqlimage,$connection);
while($rows = mysql_fetch_assoc($imageresult1))
{
echo'<img height="300" width="300" src="data:image;base64,'.$rows['image'].'">';
}
?>
If It is simple Session you can apply NULL
Check directly Session["emp_num"] != null
But if it's a session of a list Item then You need to apply any one of the following option
Option 1:
if (((List<int>)(Session["emp_num"])) != null && (List<int>)Session["emp_num"])).Count > 0)
{
//Your Logic here
}
Option 2:
List<int> val= Session["emp_num"] as List<int>; //Get the value from Session.
if (val.FirstOrDefault() != null)
{
//Your Logic here
}
A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.
A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.
(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).
The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:
You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.
In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.
This topic is very well covered in the documentation.

you have fetched just 1 row. fix like this:
while ( $tables = $result->fetch_array())
{
echo $tmp[0]."<br>";
}
and I think, information_schema would be better than SHOW TABLES
SELECT TABLE_NAME
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = 'your database name'
while ( $tables = $result->fetch_assoc())
{
echo $tables['TABLE_NAME']."<br>";
}
If you are targeting ASP.NET Core that does not support RijndaelManaged
yet, you can use IDataProtectionProvider
.
First, configure your application to use data protection:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddDataProtection();
}
// ...
}
Then you'll be able to inject IDataProtectionProvider
instance and use it to encrypt/decrypt data:
public class MyService : IService
{
private const string Purpose = "my protection purpose";
private readonly IDataProtectionProvider _provider;
public MyService(IDataProtectionProvider provider)
{
_provider = provider;
}
public string Encrypt(string plainText)
{
var protector = _provider.CreateProtector(Purpose);
return protector.Protect(plainText);
}
public string Decrypt(string cipherText)
{
var protector = _provider.CreateProtector(Purpose);
return protector.Unprotect(cipherText);
}
}
See this article for more details.
For Example:
$data = array('firstKey' => 'firstValue', 'secondKey' => 'secondValue');
For changing key value:
$data['firstKey'] = 'changedValue';
//this will change value of firstKey because firstkey is available in array
output:
Array ( [firstKey] => changedValue [secondKey] => secondValue )
For adding new key value pair:
$data['newKey'] = 'newValue';
//this will add new key and value because newKey is not available in array
output:
Array ( [firstKey] => firstValue [secondKey] => secondValue [newKey] => newValue )
Using jQuery the easiest will be:
var text = '<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>';
var output = $("<div />").html(text).text();
console.log(output);
CREATE TABLE UserGroup
(
[User_Id] INT NOT NULL,
[Group_Id] INT NOT NULL
CONSTRAINT PK_UserGroup PRIMARY KEY NONCLUSTERED ([User_Id], [Group_Id])
)
I tried all the options and none worked.
Only google app scripts helped me.
source : https://ctrlq.org/code/19649-find-duplicate-rows-in-google-sheets
At the top of your document
1.- go to tools > script editor
2.- set the name of your script
3.- paste this code :
function findDuplicates() {
// List the columns you want to check by number (A = 1)
var CHECK_COLUMNS = [1];
// Get the active sheet and info about it
var sourceSheet = SpreadsheetApp.getActiveSheet();
var numRows = sourceSheet.getLastRow();
var numCols = sourceSheet.getLastColumn();
// Create the temporary working sheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
var newSheet = ss.insertSheet("FindDupes");
// Copy the desired rows to the FindDupes sheet
for (var i = 0; i < CHECK_COLUMNS.length; i++) {
var sourceRange = sourceSheet.getRange(1,CHECK_COLUMNS[i],numRows);
var nextCol = newSheet.getLastColumn() + 1;
sourceRange.copyTo(newSheet.getRange(1,nextCol,numRows));
}
// Find duplicates in the FindDupes sheet and color them in the main sheet
var dupes = false;
var data = newSheet.getDataRange().getValues();
for (i = 1; i < data.length - 1; i++) {
for (j = i+1; j < data.length; j++) {
if (data[i].join() == data[j].join()) {
dupes = true;
sourceSheet.getRange(i+1,1,1,numCols).setBackground("red");
sourceSheet.getRange(j+1,1,1,numCols).setBackground("red");
}
}
}
// Remove the FindDupes temporary sheet
ss.deleteSheet(newSheet);
// Alert the user with the results
if (dupes) {
Browser.msgBox("Possible duplicate(s) found and colored red.");
} else {
Browser.msgBox("No duplicates found.");
}
};
4.- save and run
In less than 3 seconds, my duplicate row was colored. Just copy-past the script.

I hope this helps.
When constructing a BigInteger with a string, the string must be formatted as a decimal number. You cannot use letters, unless you specify a radix in the second argument, you can specify up to 36 in the radix. 36 will give you alphanumeric characters only [0-9,a-z], so if you use this, you will have no formatting. You can create: new BigInteger("ihavenospaces", 36) Then to convert back, use a .toString(36)
BUT TO KEEP FORMATTING: Use the byte[] method that a couple people mentioned. That will pack the data with formatting into the smallest size, and allow you to keep track of number of bytes easily
That should be perfect for an RSA public key crypto system example program, assuming you keep the number of bytes in the message smaller than the number of bytes of PQ
(I realize this thread is old)
After some trial and error, I found that
$computername = $env:computername
works to get a computer name, but sending $computername
to a file via Add-Content doesn't work.
I also tried $computername.Value
.
Instead, if I use
$computername = get-content env:computername
I can send it to a text file using
$computername | Out-File $file
A bonus would be if I can detect the specific version(s) of Excel that is(/are) installed.
I know the question has been asked and answered a long time ago, but this same question has kept me busy until I made this observation:
To get the build number (e.g. 15.0.4569.1506
), probe HKLM\SOFTWARE\Microsoft\Office\[VER]\Common\ProductVersion::LastProduct
, where [VER]
is the major version number (12.0 for Office 2007, 14.0 for Office 2010, 15.0 for Office 2013).
On a 64-bit Windows, you need to insert Wow6432Node
between the SOFTWARE
and Microsoft
crumbs, irrespective of the bitness of the Office installation.
On my machines, this gives the version information of the originally installed version. For Office 2010 for instance, the numbers match the ones listed here, and they differ from the version reported in File > Help
, which reflects patches applied by hotfixes.
I had a similar problem - authenticate device and user at device. I used a Cookie
header alongside an Authorization: Bearer...
header. One header authenticated the device, the other authenticated the user. I used a Cookie
header because these are commonly used for authentication.
Try this:
CSS:
.hidden{display:none;}
HTML:

$.ajax({
type: 'POST',
url: 'cityResults.htm',
data: $('#cityDetails').serialize(),
dataType:"json", //to parse string into JSON object,
success: function(data){
if(data){
var len = data.length;
var txt = "";
if(len > 0){
for(var i=0;i<len;i++){
if(data[i].city && data[i].cStatus){
txt += "<tr><td>"+data[i].city+"</td><td>"+data[i].cStatus+"</td></tr>";
}
}
if(txt != ""){
$("#table").append(txt).removeClass("hidden");
}
}
}
},
error: function(jqXHR, textStatus, errorThrown){
alert('error: ' + textStatus + ': ' + errorThrown);
}
});
return false;//suppress natural form submission
});
Just like any other collection. With the addition of the List<T>.ForEach
method.
foreach (var item in myMoney)
Console.WriteLine("amount is {0}, and type is {1}", item.amount, item.type);
for (int i = 0; i < myMoney.Count; i++)
Console.WriteLine("amount is {0}, and type is {1}", myMoney[i].amount, myMoney[i].type);
myMoney.ForEach(item => Console.WriteLine("amount is {0}, and type is {1}", item.amount, item.type));

Just wanted to show you a way to save all your Bundle after onConfigurationChanged:
Create new Bundle just after your class:
public class MainActivity extends Activity {
Bundle newBundy = new Bundle();
Next, after "protected void onCreate" add this:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
onSaveInstanceState(newBundy);
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
onSaveInstanceState(newBundy);
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBundle("newBundy", newBundy);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
savedInstanceState.getBundle("newBundy");
}
If you add this all your crated classes into MainActivity will be saved.
But the best way is to add this in your AndroidManifest:
<activity name= ".MainActivity" android:configChanges="orientation|screenSize"/>
var minRows = 5;
var maxRows = 26;
function ResizeTextarea(id) {
var t = document.getElementById(id);
if (t.scrollTop == 0) t.scrollTop=1;
while (t.scrollTop == 0) {
if (t.rows > minRows)
t.rows--; else
break;
t.scrollTop = 1;
if (t.rows < maxRows)
t.style.overflowY = "hidden";
if (t.scrollTop > 0) {
t.rows++;
break;
}
}
while(t.scrollTop > 0) {
if (t.rows < maxRows) {
t.rows++;
if (t.scrollTop == 0) t.scrollTop=1;
} else {
t.style.overflowY = "auto";
break;
}
}
}
Just running the SELECT
statement will have no effect on the data. You have to use an UPDATE
statement with the REPLACE
to make the change occur:
UPDATE photos
SET caption = REPLACE(caption,'"','\'')
Here is a working sample: http://sqlize.com/7FjtEyeLAh
From the documentation,
Positioning your Toast
A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the
setGravity(int, int, int)
method. This accepts three parameters: aGravity
constant, anx-position
offset, and ay-position
offset.For example, if you decide that the toast should appear in the top-left corner, you can set the gravity like this:
toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);
If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.
pack_forget
and grid_forget
will only remove widgets from view, it doesn't destroy them. If you don't plan on re-using the widgets, your only real choice is to destroy them with the destroy
method.
To do that you have two choices: destroy each one individually, or destroy the frame which will cause all of its children to be destroyed. The latter is generally the easiest and most effective.
Since you claim you don't want to destroy the container frame, create a secondary frame. Have this secondary frame be the container for all the widgets you want to delete, and then put this one frame inside the parent you do not want to destroy. Then, it's just a matter of destroying this one frame and all of the interior widgets will be destroyed along with it.
We can implement ajax request by using http service in AngularJs, which helps to read/load data from remote server.
$http service methods are listed below,
$http.get()
$http.post()
$http.delete()
$http.head()
$http.jsonp()
$http.patch()
$http.put()
One of the Example:
$http.get("sample.php")
.success(function(response) {
$scope.getting = response.data; // response.data is an array
}).error(){
// Error callback will trigger
});
These are all a matter of convenience.
Basically, if the question were 'Do we need to use body-parser
?' The answer is 'No'. We can come up with the same information from the client-post-request using a more circuitous route that will generally be less flexible and will increase the amount of code we have to write to get the same information.
This is kind of the same as asking 'Do we need to use express
to begin with?' Again, the answer there is no, and again, really it all comes down to saving us the hassle of writing more code to do the basic things that express comes with 'built-in'.
On the surface - body-parser
makes it easier to get at the information contained in client requests in a variety of formats instead of making you capture the raw data streams and figuring out what format the information is in, much less manually parsing that information into useable data.
A bat file has no structure...it is how you would type it on the command line. So just open your favourite editor..copy the line of code you want to run..and save the file as whatever.bat or whatever.cmd
Your working tree is what is actually in the files that you are currently working on.
HEAD
is a pointer to the branch or commit that you last checked out, and which will be the parent of a new commit if you make it. For instance, if you're on the master
branch, then HEAD
will point to master
, and when you commit, that new commit will be a descendent of the revision that master
pointed to, and master
will be updated to point to the new commit.
The index is a staging area where the new commit is prepared. Essentially, the contents of the index are what will go into the new commit (though if you do git commit -a
, this will automatically add all changes to files that Git knows about to the index before committing, so it will commit the current contents of your working tree). git add
will add or update files from the working tree into your index.
OK I was able to solve this myself:
$(document).ready(function() {
$('#tid_css').DataTable({
"iDisplayLength": 100,
"bFilter": false,
"aaSorting": [
[2, "desc"]
],
"fnRowCallback": function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
if (aData[2] == "5") {
$('td', nRow).css('background-color', 'Red');
} else if (aData[2] == "4") {
$('td', nRow).css('background-color', 'Orange');
}
}
});
})
For languages not specifying a memory model, you are writing code for the language and the memory model specified by the processor architecture. The processor may choose to re-order memory accesses for performance. So, if your program has data races (a data race is when it's possible for multiple cores / hyper-threads to access the same memory concurrently) then your program is not cross platform because of its dependence on the processor memory model. You may refer to the Intel or AMD software manuals to find out how the processors may re-order memory accesses.
Very importantly, locks (and concurrency semantics with locking) are typically implemented in a cross platform way... So if you are using standard locks in a multithreaded program with no data races then you don't have to worry about cross platform memory models.
Interestingly, Microsoft compilers for C++ have acquire / release semantics for volatile which is a C++ extension to deal with the lack of a memory model in C++ http://msdn.microsoft.com/en-us/library/12a04hfd(v=vs.80).aspx. However, given that Windows runs on x86 / x64 only, that's not saying much (Intel and AMD memory models make it easy and efficient to implement acquire / release semantics in a language).
I recently moved a site using SimplePie (http://simplepie.org/) from a server that was using PHP 5.2.17 to one that is using PHP 5.3.2. It was after this move that I began receiving a list of error messages such as this one:
Deprecated: Assigning the return value of new by reference is deprecated in .../php/simplepie.inc on line 738
After reviewing several discussions of this issue, I cleared things up by replacing all the instances of =& new with = new in the simplepie.inc file.
I'm not experienced enough to know if this will work in all instances where these error messages are received but it worked in this particular case and it may be worth trying.
for i in count:
means for i in 7:
, which won't work. The bit after the in
should be of an iterable type, not a number. Try this:
for i in range(count):
int
is a primitive type. Variables of type int
store the actual binary value for the integer you want to represent. int.parseInt("1")
doesn't make sense because int
is not a class and therefore doesn't have any methods.
Integer
is a class, no different from any other in the Java language. Variables of type Integer
store references to Integer
objects, just as with any other reference (object) type. Integer.parseInt("1")
is a call to the static method parseInt
from class Integer
(note that this method actually returns an int
and not an Integer
).
To be more specific, Integer
is a class with a single field of type int
. This class is used where you need an int
to be treated like any other object, such as in generic types or situations where you need nullability.
Note that every primitive type in Java has an equivalent wrapper class:
byte
has Byte
short
has Short
int
has Integer
long
has Long
boolean
has Boolean
char
has Character
float
has Float
double
has Double
Wrapper classes inherit from Object class, and primitive don't. So it can be used in collections with Object reference or with Generics.
Since java 5 we have autoboxing, and the conversion between primitive and wrapper class is done automatically. Beware, however, as this can introduce subtle bugs and performance problems; being explicit about conversions never hurts.
With recent browsers you can use the HTML5 download attribute as well:
<a download="quot.pdf" href="../doc/quot.pdf">Click here to Download quotation</a>
It is supported by most of the recent browsers except MSIE11. You can use a polyfill, something like this (note that this is for data uri only, but it is a good start):
(function (){
addEvent(window, "load", function (){
if (isInternetExplorer())
polyfillDataUriDownload();
});
function polyfillDataUriDownload(){
var links = document.querySelectorAll('a[download], area[download]');
for (var index = 0, length = links.length; index<length; ++index) {
(function (link){
var dataUri = link.getAttribute("href");
var fileName = link.getAttribute("download");
if (dataUri.slice(0,5) != "data:")
throw new Error("The XHR part is not implemented here.");
addEvent(link, "click", function (event){
cancelEvent(event);
try {
var dataBlob = dataUriToBlob(dataUri);
forceBlobDownload(dataBlob, fileName);
} catch (e) {
alert(e)
}
});
})(links[index]);
}
}
function forceBlobDownload(dataBlob, fileName){
window.navigator.msSaveBlob(dataBlob, fileName);
}
function dataUriToBlob(dataUri) {
if (!(/base64/).test(dataUri))
throw new Error("Supports only base64 encoding.");
var parts = dataUri.split(/[:;,]/),
type = parts[1],
binData = atob(parts.pop()),
mx = binData.length,
uiArr = new Uint8Array(mx);
for(var i = 0; i<mx; ++i)
uiArr[i] = binData.charCodeAt(i);
return new Blob([uiArr], {type: type});
}
function addEvent(subject, type, listener){
if (window.addEventListener)
subject.addEventListener(type, listener, false);
else if (window.attachEvent)
subject.attachEvent("on" + type, listener);
}
function cancelEvent(event){
if (event.preventDefault)
event.preventDefault();
else
event.returnValue = false;
}
function isInternetExplorer(){
return /*@cc_on!@*/false || !!document.documentMode;
}
})();
I understand you intention well, I use buffers exclusively too, and occasionally do split if needed.
below is excerpt of my .vimrc
" disable macro, since not used in 90+% use cases
map q <Nop>
" q, close/hide current window, or quit vim if no other window
nnoremap q :if winnr('$') > 1 \|hide\|else\|silent! exec 'q'\|endif<CR>
" qo, close all other window -- 'o' stands for 'only'
nnoremap qo :only<CR>
set hidden
set timeout
set timeoutlen=200 " let vim wait less for your typing!
Which fits my workflow quite well
If
q
was pressed
- hide current window if multiple window open, else try to quit vim.
if
qo
was pressed,
- close all other window, no effect if only one window.
Of course, you can wrap that messy part into a function, eg
func! Hide_cur_window_or_quit_vim()
if winnr('$') > 1
hide
else
silent! exec 'q'
endif
endfunc
nnoremap q :call Hide_cur_window_or_quit_vim()<CR>
Sidenote:
I remap q
, since I do not use macro for editing, instead use :s
, :g
, :v
, and external text processing command if needed, eg, :'{,'}!awk 'some_programm'
, or use :norm! normal-command-here
.
For python 3.6
class SomeClass:
def attr_list(self, should_print=False):
items = self.__dict__.items()
if should_print:
[print(f"attribute: {k} value: {v}") for k, v in items]
return items
scanf
needs to know the size of the data being pointed at by &d
to fill it properly, whereas variadic functions promote floats to doubles (not entirely sure why), so printf
is always getting a double
.
You don't need to escape it inside. You can use the |
character to delimit searches.
"\"foo\"\'bar\'".replace(/("|')/g, "")
This should be faster than iterating and will work regardless of shape.
numpy.isnan(myarray).any()
Edit: 30x faster:
import timeit
s = 'import numpy;a = numpy.arange(10000.).reshape((100,100));a[10,10]=numpy.nan'
ms = [
'numpy.isnan(a).any()',
'any(numpy.isnan(x) for x in a.flatten())']
for m in ms:
print " %.2f s" % timeit.Timer(m, s).timeit(1000), m
Results:
0.11 s numpy.isnan(a).any()
3.75 s any(numpy.isnan(x) for x in a.flatten())
Bonus: it works fine for non-array NumPy types:
>>> a = numpy.float64(42.)
>>> numpy.isnan(a).any()
False
>>> a = numpy.float64(numpy.nan)
>>> numpy.isnan(a).any()
True
In my case a dependency was missing in the dll that threw this exception. I checked with Dependency Walker, added the missing dll and the problem was resolved.
More specifically, I somehow corrupted my opencv_core340.dll by accidentally adding SVN keywords to it, and thus my dll could no longer use it. However I don't believe that the solution to this problem depends on whether the dll is corrupted or missing. I'm just adding this for the sake of giving complete information.
FWIW, I didn't have any success with the spring.resources.static-locations
recommended above; what worked for me was setting spring.thymeleaf.prefix:
report.location=file:/Users/bill/report/html/
spring.thymeleaf.prefix=${report.location}
I don't know if the solution below is more or less efficient than jspcal's answer, but I'm pretty sure it requires less object creation than Jamie's and George's.
string s = "THIS IS MY TEXT RIGHT NOW";
StringBuilder sb = new StringBuilder(s.Length);
bool capitalize = true;
foreach (char c in s) {
sb.Append(capitalize ? Char.ToUpper(c) : Char.ToLower(c));
capitalize = !Char.IsLetter(c);
}
return sb.ToString();
If you are the only the person working on the project, what you can do is:
git checkout master
git push origin +HEAD
This will set the tip of origin/master to the same commit as master (and so delete the commits between 41651df and origin/master)
Try AddRange-method:
GlobalStrings.AddRange(localStrings);
And in clean javascript:
var texts = [], lis = document.getElementsByTagName("li");
for(var i=0, im=lis.length; im>i; i++)
texts.push(lis[i].firstChild.nodeValue);
alert(texts);

I would suggest this for matching Chrome's style, extended from Jarish's example. Notice the cursor property which previous answers have omitted.
cursor: text;
border: 1px solid #ccc;
font: medium -moz-fixed;
font: -webkit-small-control;
height: 200px;
overflow: auto;
padding: 2px;
resize: both;

file = open('parsed_data.txt', 'w')
for link in soup.findAll('a', attrs={'href': re.compile("^http")}): print (link)
soup_link = str(link)
print (soup_link)
file.write(soup_link)
file.flush()
file.close()
In my case, I used BeautifulSoup to write a .txt with Python 3.x. It had the same issue. Just as @tsduteba said, change the 'wb' in the first line to 'w'.
I use a for loop to iterate the string and use charAt()
to get each character to examine it. Since the String is implemented with an array, the charAt()
method is a constant time operation.
String s = "...stuff...";
for (int i = 0; i < s.length(); i++){
char c = s.charAt(i);
//Process char
}
That's what I would do. It seems the easiest to me.
As far as correctness goes, I don't believe that exists here. It is all based on your personal style.
My code is:
s=["9"]*int(input())
for I in range(len(s)):
while not set(s[I])<=set('01'):s[i]=input(i)
print(bin(sum([int(x,2)for x in s]))[2:])
It is a binary adder but I don't think the range len or the inside can be replaced to make it smaller/better.
I believe that @Matthew Crumley is right. They are functionally, if not structurally, equivalent. If you use Firebug to look at the objects that are created using new
, you can see that they are the same. However, my preference would be the following. I'm guessing that it just seems more like what I'm used to in C#/Java. That is, define the class, define the fields, constructor, and methods.
var A = function() {};
A.prototype = {
_instance_var: 0,
initialize: function(v) { this._instance_var = v; },
x: function() { alert(this._instance_var); }
};
EDIT Didn't mean to imply that the scope of the variable was private, I was just trying to illustrate how I define my classes in javascript. Variable name has been changed to reflect this.
Change Background Color using on click button jquery
Below is the code of jquery, which you can put in your head tag.
jQuery Code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("div").addClass("myclass");
});
});
</script>
CSS Code:
<style>
.myclass {
background-color: red;
padding: 100px;
color: #fff;
}
</style>
HTML Code:
<body>
<div>Lorem Ipsum is simply dummy text of the printing and typesetting industry.</div>
<button>Click Here</button>
</body>
Just add:
left: calc(-50vw + 50%);
right: calc(-50vw + 50%);
margin-left: auto;
margin-right: auto;
For PHP version 4 or later versions:
<?PHP
$input = 4;
if(is_numeric($input)){ // return **TRUE** if it is numeric
echo "The input is numeric";
}else{
echo "The input is not numeric";
}
?>
Start by selecting the sheets you want to combine:
ThisWorkbook.Sheets(Array("Sheet1", "Sheet2")).Select
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"C:\tempo.pdf", Quality:= xlQualityStandard, IncludeDocProperties:=True, _
IgnorePrintAreas:=False, OpenAfterPublish:=True
Of course, all modern browsers now support the following simpler way:
var elements = document.getElementsByClassName('someClass');
but be warned it doesn't work with IE8 or before. See http://caniuse.com/getelementsbyclassname
Also, not all browsers will return a pure NodeList
like they're supposed to.
You're probably still better off using your favorite cross-browser library.
You can modify the .form-control:focus
color without altering the bootstrap style in this way:
.form-control:focus {
border-color: #28a745;
box-shadow: 0 0 0 0.2rem rgba(40, 167, 69, 0.25);
}
.form-control:focus
and copy the parameters that you want to modify into your css. In this case is border-color
and box-shadow
.border-color
. In this case I choose to pick up the same green the bootstrap uses for their .btn-success
class, by searching for that particular class in the bootstrap.css page mentioned in the step 1.box-shadow
parameter without altering the fourth RGBA parameter (0.25) that bootstrap has for transparency.You could use a library like jQuery and its $.post method.
In SQL Server 2005+ with Full-Text indexing switched on, I'd do the following:
SELECT *
FROM T
WHERE CONTAINS(C, '"David" OR "Robi" OR "Moses"');
If you wanted your search to bring back results where the result is prefixed with David, Robi or Moses you could do:
SELECT *
FROM T
WHERE CONTAINS(C, '"David*" OR "Robi*" OR "Moses*"');
As someone familiar with Visual Studio, I've looked at several open source IDE's to replace it, and KDevelop comes the closest IMO to being something that a Visual C++ person can just sit down and start using. When you run the project in debugging mode, it uses gdb but kdevelop pretty much handles the whole thing so that you don't have to know it's gdb; you're just single stepping or assigning watches to variables.
It still isn't as good as the Visual Studio Debugger, unfortunately.
Just create the database using createdb
CLI tool:
PGHOST="my.database.domain.com"
PGUSER="postgres"
PGDB="mydb"
createdb -h $PGHOST -p $PGPORT -U $PGUSER $PGDB
If the database exists, it will return an error:
createdb: database creation failed: ERROR: database "mydb" already exists
I have faced the same issue and this is what I did to resolve it:
In the WebApi service, inside Global.asax I have written the following code:
Sub Application_BeginRequest()
Dim currentRequest = HttpContext.Current.Request
Dim currentResponse = HttpContext.Current.Response
Dim currentOriginValue As String = String.Empty
Dim currentHostValue As String = String.Empty
Dim currentRequestOrigin = currentRequest.Headers("Origin")
Dim currentRequestHost = currentRequest.Headers("Host")
Dim currentRequestHeaders = currentRequest.Headers("Access-Control-Request-Headers")
Dim currentRequestMethod = currentRequest.Headers("Access-Control-Request-Method")
If currentRequestOrigin IsNot Nothing Then
currentOriginValue = currentRequestOrigin
End If
If currentRequest.Path.ToLower().IndexOf("token") > -1 Or Request.HttpMethod = "OPTIONS" Then
currentResponse.Headers.Remove("Access-Control-Allow-Origin")
currentResponse.AppendHeader("Access-Control-Allow-Origin", "*")
End If
For Each key In Request.Headers.AllKeys
If key = "Origin" AndAlso Request.HttpMethod = "OPTIONS" Then
currentResponse.AppendHeader("Access-Control-Allow-Credentials", "true")
currentResponse.AppendHeader("Access-Control-Allow-Methods", currentRequestMethod)
currentResponse.AppendHeader("Access-Control-Allow-Headers", If(currentRequestHeaders, "GET,POST,PUT,DELETE,OPTIONS"))
currentResponse.StatusCode = 200
currentResponse.End()
End If
Next
End Sub
Here this code only allows pre-flight and token request to add "Access-Control-Allow-Origin" in the response otherwise I am not adding it.
Here is my blog about the implementation: https://ibhowmick.wordpress.com/2018/09/21/cross-domain-token-based-authentication-with-web-api2-and-jquery-angular-5-angular-6/

Generally, you just need to update constraints and call layoutIfNeeded
inside the animation block. This can be either changing the .constant
property of an NSLayoutConstraint
, adding remove constraints (iOS 7), or changing the .active
property of constraints (iOS 8 & 9).
[UIView animateWithDuration:0.3 animations:^{
// Move to right
self.leadingConstraint.active = false;
self.trailingConstraint.active = true;
// Move to bottom
self.topConstraint.active = false;
self.bottomConstraint.active = true;
// Make the animation happen
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];
There are some questions about whether the constraint should be changed before the animation block, or inside it (see previous answers).
The following is a Twitter conversation between Martin Pilkington who teaches iOS, and Ken Ferry who wrote Auto Layout. Ken explains that though changing constants outside of the animation block may currently work, it's not safe and they should really be change inside the animation block. https://twitter.com/kongtomorrow/status/440627401018466305
Here's a simple project showing how a view can be animated. It's using Objective C and animates the view by changing the .active
property of several constraints.

This post describes it very nicely.
In short: utf8_unicode_ci
uses the Unicode Collation Algorithm as defined in the Unicode standards, whereas utf8_general_ci
is a more simple sort order which results in "less accurate" sorting results.
You could use penlight library. This has a function for splitting string using delimiter which outputs list.
It has implemented many of the function that we may need while programming and missing in Lua.
Here is the sample for using it.
>
> stringx = require "pl.stringx"
>
> str = "welcome to the world of lua"
>
> arr = stringx.split(str, " ")
>
> arr
{welcome,to,the,world,of,lua}

document.getElementsByName("name")
will get several elements called by same name .
document.getElementsByName("name")[Number]
will get one of them.
document.getElementsByName("name")[Number].value
will get the value of paticular element.
The key of this question is this:
The name of elements is not unique, it is usually used for several input elements in the form.
On the other hand, the id of the element is unique, which is the only definition for a particular element in a html file.
UIAlertViews
use a delegate to communicate with you, the client.
You add a second button, and you create an object to receive the delegate messages from the view:
class LogInErrorDelegate : UIAlertViewDelegate {
init {}
// not sure of the prototype of this, you should look it up
func alertView(view :UIAlertView, clickedButtonAtIndex :Integer) -> Void {
switch clickedButtonAtIndex {
case 0:
userClickedOK() // er something
case 1:
userClickedRetry()
/* Don't use "retry" as a function name, it's a reserved word */
default:
userClickedRetry()
}
}
/* implement rest of the delegate */
}
logInErrorAlert.addButtonWithTitle("Retry")
var myErrorDelegate = LogInErrorDelegate()
logInErrorAlert.delegate = myErrorDelegate
It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:
When location matches the last part of the directive’s value: it is better to use the root directive instead:
which would yield:
server {
listen 8080;
server_name www.mysite.com mysite.com;
error_log /home/www-data/logs/nginx_www.error.log;
error_page 404 /404.html;
location /public/doc/ {
autoindex on;
root /home/www-data/mysite;
}
location = /404.html {
root /home/www-data/mysite/static/html;
}
}
Update (2016):
If you only need SOAP client, there is well maintained library called zeep. It supports both Python 2 and 3 :)
Update:
Additionally to what is mentioned above, I will refer to Python WebServices page which is always up-to-date with all actively maintained and recommended modules to SOAP and all other webservice types.
Unfortunately, at the moment, I don't think there is a "best" Python SOAP library. Each of the mainstream ones available has its own pros and cons.
Older libraries:
SOAPy: Was the "best," but no longer maintained. Does not work on Python 2.5+
ZSI: Very painful to use, and development is slow. Has a module called "SOAPpy", which is different than SOAPy (above).
"Newer" libraries:
SUDS: Very Pythonic, and easy to create WSDL-consuming SOAP clients. Creating SOAP servers is a little bit more difficult. (This package does not work with Python3. For Python3 see SUDS-py3)
SUDS-py3: The Python3 version of SUDS
spyne: Creating servers is easy, creating clients a little bit more challenging. Documentation is somewhat lacking.
ladon: Creating servers is much like in soaplib (using a decorator). Ladon exposes more interfaces than SOAP at the same time without extra user code needed.
pysimplesoap: very lightweight but useful for both client and server - includes a web2py server integration that ships with web2py.
Of the above, I've only used SUDS personally, and I liked it a lot.
Best approach:
function playPauseThisVideo(this_video_id) {
var this_video = document.getElementById(this_video_id);
if (this_video.paused) {
console.log("VIDEO IS PAUSED");
} else {
console.log("VIDEO IS PLAYING");
}
}
I did a fun hack to solve this issue to my satisfaction. I've got an AJAX site that loads content dynamically, then modifies the window.location.hash, and I had code to run upon $(document).ready() to parse the hash and load the appropriate section. The thing is that I was perfectly happy with my section loading code for navigation, but wanted to add a way to intercept the browser back and forward buttons, which change the window location, but not interfere with my current page loading routines where I manipulate the window.location, and polling the window.location at constant intervals was out of the question.
What I ended up doing was creating an object as such:
var pageload = {
ignorehashchange: false,
loadUrl: function(){
if (pageload.ignorehashchange == false){
//code to parse window.location.hash and load content
};
}
};
Then, I added a line to my site script to run the pageload.loadUrl
function upon the hashchange event, as such:
window.addEventListener("hashchange", pageload.loadUrl, false);
Then, any time I want to modify the window.location.hash
without triggering this page loading routine, I simply add the following line before each window.location.hash =
line:
pageload.ignorehashchange = true;
and then the following line after each hash modification line:
setTimeout(function(){pageload.ignorehashchange = false;}, 100);
So now my section loading routines are usually running, but if the user hits the 'back' or 'forward' buttons, the new location is parsed and the appropriate section loaded.
I haven't tested this, but you might try using PipedInputStream and PipedOutputStream. It might look something like:
final Bitmap bmp = … // your bitmap
// Set up Piped streams
final PipedOutputStream pos = new PipedOutputStream(new ByteArrayOutputStream());
final PipedInputStream pis = new PipedInputStream(pos);
// Send bitmap data to the PipedOutputStream in a separate thread
new Thread() {
public void run() {
bmp.compress(Bitmap.CompressFormat.PNG, 100, pos);
}
}.start();
// Send POST request
try {
// Construct InputStreamEntity that feeds off of the PipedInputStream
InputStreamEntity reqEntity = new InputStreamEntity(pis, -1);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
} catch (Exception e) {
e.printStackTrace()
}
find($id)
takes an id and returns a single model. If no matching model exist, it returns null
.
findOrFail($id)
takes an id and returns a single model. If no matching model exist, it throws an error1.
first()
returns the first record found in the database. If no matching model exist, it returns null
.
firstOrFail()
returns the first record found in the database. If no matching model exist, it throws an error1.
get()
returns a collection of models matching the query.
pluck($column)
returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists
.
toArray()
converts the model/collection into a simple PHP array.
Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.
Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach
loop is ok, put passing it to array_map
is not. Similarly, if you type-hint an argument as array
, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable
typehint, which can be used to accept both arrays and collections.
If you ever want to get a plain array from a collection, call its all()
method.
1 The error thrown by the findOrFail
and firstOrFail
methods is a ModelNotFoundException
. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.
As @Richard pointed out above, the onClick needs to have a capital 'C'.
$('#stop').click(function() {
$('next').attr('onClick','stopMoving()');
}

Can you make and edit a collection of objects from an enum? Yes.
If you do not care about the order, use EnumSet
, an implementation of Set
.
enum Animal{ DOG , CAT , BIRD , BAT ; }
Set<Animal> flyingAnimals = EnumSet.of( BIRD , BAT );
Set<Animal> featheredFlyingAnimals = flyingAnimals.clone().remove( BAT ) ;
If you care about order, use a List
implementation such as ArrayList
. For example, we can create a list of a person’s preference in choosing a pet, in the order of their most preferred.
List< Animal > favoritePets = new ArrayList<>() ;
favoritePets.add( CAT ) ; // This person prefers cats over dogs…
favoritePets.add( DOG ) ; // …but would accept either.
// This person would not accept a bird nor a bat.
For a non-modifiable ordered list, use List.of
.
List< Animal > favoritePets = List.of( CAT , DOG ) ; // This person prefers cats over dogs, but would accept either. This person would not accept a bird nor a bat.
The Answer (EnumSet
) by Amit Deshpande and the Answer (.values
) by Marko Topolnik are both correct. Here is a bit more info.
Enum.values
The .values()
method is an implicitly declared method on Enum
, added by the compiler. It produces a crude array rather than a Collection
. Certainly usable.
Special note about documentation: Being unusual as an implicitly declared method, the .values()
method is not listed among the methods on the Enum
class. The method is defined in the Java Language Specification, and is mentioned in the doc for Enum.valueOf
.
EnumSet
– Fast & SmallThe upsides to EnumSet
include:
To quote the class doc:
Enum sets are represented internally as bit vectors. This representation is extremely compact and efficient. The space and time performance of this class should be good enough to allow its use as a high-quality, typesafe alternative to traditional int-based "bit flags." Even bulk operations (such as containsAll and retainAll) should run very quickly if their argument is also an enum set.
Given this enum:
enum Animal
{
DOG , CAT , BIRD , BAT ;
}
Make an EnumSet
in one line.
Set<Animal> allAnimals = EnumSet.allOf( Animal.class );
Dump to console.
System.out.println( "allAnimals : " + allAnimals );
allAnimals : [DOG, CAT, BIRD, BAT]
Make a set from a subset of the enum objects.
Set<Animal> flyingAnimals = EnumSet.of( BIRD , BAT );
Look at the class doc to see many ways to manipulate the collection including adding or removing elements.
Set<Animal> featheredFlyingAnimals =
EnumSet.copyOf( flyingAnimals ).remove( BAT );
The doc promises the Iterator for EnumSet is in natural order, the order in which the values of the enum were originally declared.
To quote the class doc:
The iterator returned by the iterator method traverses the elements in their natural order (the order in which the enum constants are declared).
Frankly, given this promise, I'm confused why this is not a SortedSet
. But, oh well, good enough. We can create a List
from the Set
if desired. Pass any Collection
to constructor of ArrayList
and that collection’s Iterator
is automatically called on your behalf.
List<Animal> list = new ArrayList<>( allAnimals );
Dump to console.
System.out.println("list : " + list );
When run.
list : [DOG, CAT, BIRD, BAT]
In Java 10 and later, you can conveniently create a non-modifiable List
by passing the EnumSet
. The order of the new list will be in the iterator order of the EnumSet
. The iterator order of an EnumSet
is the order in which the element objects of the enum were defined on that enum.
List< Animal > nonModList = List.copyOf( allAnimals ) ; // Or pass Animals.values()
You can use the new URL for Google Maps: https://www.google.com/maps/@39.774769,-74.86084,18z equivalent to http://maps.google.com/?ll=39.774769,-74.86084.
39.774769 is the latitude and -74.86084 is longitude and 18z is 18 zoom level.
Here's one that works (see the example):
function updateTextArea() {
var allVals = [];
$('#c_b :checked').each(function() {
allVals.push($(this).val());
});
$('#t').val(allVals);
}
$(function() {
$('#c_b input').click(updateTextArea);
updateTextArea();
});
Some number of months later another question was asked in regards to how to keep the above working if the ID changes. Well, the solution boils down to mapping the updateTextArea function into something generic that uses CSS classes, and to use the live function to monitor the DOM for those changes.
Why not update the files on the local file system instead? You can read/write files into your applications sandboxed area.

Other alternatives you may want to look into are Shared Perferences and using Cache Files (all described at the link above)

inplace=True
makes the function impure. It changes the original dataframe and returns None. In that case, You breaks the DSL chain.
Because most of dataframe functions return a new dataframe, you can use the DSL conveniently. Like
df.sort_values().rename().to_csv()
Function call with inplace=True
returns None and DSL chain is broken. For example
df.sort_values(inplace=True).rename().to_csv()
will throw NoneType object has no attribute 'rename'
Something similar with python’s build-in sort and sorted. lst.sort()
returns None
and sorted(lst)
returns a new list.
Generally, do not use inplace=True
unless you have specific reason of doing so. When you have to write reassignment code like df = df.sort_values()
, try attaching the function call in the DSL chain, e.g.
df = pd.read_csv().sort_values()...
To edit Date in oracle you can try
select to_char(<columnName> + 5 / 24 + 30 / (24 * 60),
'DD/MM/RRRR hh:mi AM') AS <logicalName> from <tableName>
how about sysdate?
SELECT field,datetime_field
FROM database
WHERE datetime_field > (sysdate-1)
Initializer block is just like any bits of code; it's not "attached" to any field/method preceding it. To assign values to fields, you have to explicitly use the field as the lhs of an assignment statement.
private int lineCount; {
try{
lineCount = LineCounter.countLines(sFileName);
/*^^^^^^^*/
}
catch(IOException ex){
System.out.println (ex.toString());
System.out.println("Could not find file " + sFileName);
}
}
Also, your countLines
can be made simpler:
public static int countLines(String filename) throws IOException {
LineNumberReader reader = new LineNumberReader(new FileReader(filename));
while (reader.readLine() != null) {}
reader.close();
return reader.getLineNumber();
}
Based on my test, it looks like you can getLineNumber()
after close()
.
Though this question has been answered. I would like to put something extra, i.e. if there is a file exist with the directory name that you are trying to create than it should prompt an error. For future visitors.
public static void makeDir()
{
File directory = new File(" dirname ");
if (directory.exists() && directory.isFile())
{
System.out.println("The dir with name could not be" +
" created as it is a normal file");
}
else
{
try
{
if (!directory.exists())
{
directory.mkdir();
}
String username = System.getProperty("user.name");
String filename = " path/" + username + ".txt"; //extension if you need one
}
catch (IOException e)
{
System.out.println("prompt for error");
}
}
}

return false;
});

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:
Dim MyVar as string = "some text ""hello"" "
This will give the MyVar
variable a value of some text "hello"
.
Using netsh with connectaddress=127.0.0.1 did not work for me.
Despite looking everywhere on the internet I could not find the solution which solved this for me, which was to use connectaddress=127.x.x.x (i.e. any 127. ipv4 address, just not 127.0.0.1) as this appears to link back to localhost just the same but without the restriction, so that the loopback works in netsh.
No need to store it anywhere. Just output the content with the appropriate content type.
<?php
header('Content-type: text/plain');
?>Hello, world.
Add content-disposition if you wish to trigger a download prompt.
header('Content-Disposition: attachment; filename="default-filename.txt"');
Pretty simple
public class SomeClass{
private int number;
private String someString;
public SomeClass(){
number = 0;
someString = new String();
}
public SomeClass(int number){
this(); //set the class to 0
this.setNumber(number);
}
public SomeClass(int number, String someString){
this(number); //call public SomeClass( int number )
this.setString(someString);
}
public void setNumber(int number){
this.number = number;
}
public void setString(String someString){
this.someString = someString;
}
//.... add some accessors
}
now here is some small extra credit:
public SomeOtherClass extends SomeClass {
public SomeOtherClass(int number, String someString){
super(number, someString); //calls public SomeClass(int number, String someString)
}
//.... Some other code.
}
Hope this helps.
You have to add the android:screenOrientation="portrait"
directive in your AndroidManifest.xml
. This is to be done in your <activity>
tag.
In addition, the Android Developers guide states that :
[...] you should also explicitly declare that your application requires either portrait or landscape orientation with the element. For example,
<uses-feature android:name="android.hardware.screen.portrait" />

To get the shape as a list of ints, do tensor.get_shape().as_list()
.
To complete your tf.shape()
call, try tensor2 = tf.reshape(tensor, tf.TensorShape([num_rows*num_cols, 1]))
. Or you can directly do tensor2 = tf.reshape(tensor, tf.TensorShape([-1, 1]))
where its first dimension can be inferred.

The project type set as the Start-up project in that solution is of type ClassLibrary. DUe to that, the output is a dll not an executable and so, you cannot start it.
If this is an error then you can do this:
A quick and dirty fix for this, if that is the only csproj in the solution is to open the .csproj file in a text editor and change the value of the node <ProjectGuid>
to the Guid corresponding to a WinForms C# project. (That you may obtain from a google search or by creating a new project and opening the .csproj file generated by Visual Studio to find out what the GUID for that type is). (Enjoy - not many people know about this sneaky trick)
BUT: the project might be a class library rightfully and then you should reference it in another project and use it that way.
With the help of ceztko's answer I wrote this little helper function to make my life easier:
function gpu()
{
if git rev-parse --abbrev-ref --symbolic-full-name @{u} > /dev/null 2>&1; then
git push origin HEAD
else
git push -u origin HEAD
fi
}
It pushes the current branch to origin and also sets the remote tracking branch if it hasn't been setup yet.
if it is a Spring boot App.
Spring Boot automatically detects index.html in public/static/webapp folder. If you have written any controller @Requestmapping("/")
it will override the default feature and it will not show the index.html
unless you type localhost:8080/index.html
An anonymous class is extending or implementing while creating its object For example :
Interface in = new InterFace()

}
Here anonymous class is implementing Interface.
Class cl = new Class(){

By default, the docker daemon will use the unix socket unix:///var/run/docker.sock
(you can check this is the case for you by doing a sudo netstat -tunlp
and note that there is no docker daemon process listening on any ports). It's recommended to keep this setting for security reasons but it sounds like Riak requires the daemon to be running on a TCP socket.
To start the docker daemon with a TCP socket that anybody can connect to, use the -H
option:
sudo docker -H 0.0.0.0:2375 -d &
Warning: This means machines that can talk to the daemon through that TCP socket can get root access to your host machine.

This might be of help to some. I had two projects, one which was a copy of the demo from Google and that worked fine. Another I copied into an existing project and I could not get it to run at all. And in the second failing one I was getting the error message described above.
My problem was due to a library not enabled, even though I rebuilt, imported multiple times etc. Right-click on the project -> Properties -> Java Build Path -> Order & Export tab. On the failing project the "Android Private Libraries" tab was unchecked.
Once I enabled it the project worked fine.
mute=1

as suggested by @Fab will work. However, if you wish to enable autoplay with sound you should add allow="autoplay"
to your embedded <iframe>
.
<iframe type="text/html" src="https://www.youtube.com/embed/-ePDPGXkvlw?autoplay=1" frameborder="0" allow="autoplay"></iframe>
This is officially supported and documented in Google's Autoplay Policy Changes 2017 post
Iframe delegation A feature policy allows developers to selectively enable and disable use of various browser features and APIs. Once an origin has received autoplay permission, it can delegate that permission to cross-origin iframes with a new feature policy for autoplay. Note that autoplay is allowed by default on same-origin iframes.
<!-- Autoplay is allowed. --> <iframe src="https://cross-origin.com/myvideo.html" allow="autoplay"> <!-- Autoplay and Fullscreen are allowed. --> <iframe src="https://cross-origin.com/myvideo.html" allow="autoplay; fullscreen">
When the feature policy for autoplay is disabled, calls to play() without a user gesture will reject the promise with a NotAllowedError DOMException. And the autoplay attribute will also be ignored.
To add to tacaswell's answer, the colorbar()
function has an optional cax
input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)

cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')
cax.set_xlabel('data label') # cax == cb.ax
I don't think any of these answers are quite right/optimal. NameValueCollection not only doesn't distinguish between null values and missing values, it's also case-insensitive with regards to it's keys. Thus, I think a full solution would be:
public static bool ContainsKey(this NameValueCollection @this, string key)
{
return @this.Get(key) != null
// I'm using Keys instead of AllKeys because AllKeys, being a mutable array,
// can get out-of-sync if mutated (it weirdly re-syncs when you modify the collection).
// I'm also not 100% sure that OrdinalIgnoreCase is the right comparer to use here.
// The MSDN docs only say that the "default" case-insensitive comparer is used
// but it could be current culture or invariant culture
|| @this.Keys.Cast<string>().Contains(key, StringComparer.OrdinalIgnoreCase);
}
There is now (as of v1.10.7) a fourth way to instantiate mocks, which is using a JUnit4 rule called MockitoRule.
@RunWith(JUnit4.class) // or a different runner of your choice
public class YourTest
@Rule public MockitoRule rule = MockitoJUnit.rule();
@Mock public YourMock yourMock;
@Test public void yourTestMethod() { /* ... */ }
}
JUnit looks for subclasses of TestRule annotated with @Rule, and uses them to wrap the test Statements that the Runner provides. The upshot of this is that you can extract @Before methods, @After methods, and even try...catch wrappers into rules. You can even interact with these from within your test, the way that ExpectedException does.
MockitoRule behaves almost exactly like MockitoJUnitRunner, except that you can use any other runner, such as Parameterized (which allows your test constructors to take arguments so your tests can be run multiple times), or Robolectric's test runner (so its classloader can provide Java replacements for Android native classes). This makes it strictly more flexible to use in recent JUnit and Mockito versions.
In summary:
Mockito.mock()
: Direct invocation with no annotation support or usage validation.MockitoAnnotations.initMocks(this)
: Annotation support, no usage validation.MockitoJUnitRunner
: Annotation support and usage validation, but you must use that runner.MockitoRule
: Annotation support and usage validation with any JUnit runner.See also: How JUnit @Rule works?
You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.
You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig
. It will give out some information and your local IP should look like 192.168.1.x.
The simplest and most elegant way is as follows:
all(x==myList[0] for x in myList)
(Yes, this even works with the empty list! This is because this is one of the few cases where python has lazy semantics.)
Regarding performance, this will fail at the earliest possible time, so it is asymptotically optimal.

To delete a cookie I set it again with an empty value and expiring in 1 second. In details, I always use one of the following flavours (I tend to prefer the second one):
1.
function setCookie(key, value, expireDays, expireHours, expireMinutes, expireSeconds) {
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = key +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie(name, "", null , null , null, 1);
}
Usage:
setCookie("reminder", "buyCoffee", null, null, 20);
deleteCookie("reminder");
2
function setCookie(params) {
var name = params.name,
value = params.value,
expireDays = params.days,
expireHours = params.hours,
expireMinutes = params.minutes,
expireSeconds = params.seconds;
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = name +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie({name: name, value: "", seconds: 1});
}
Usage:
setCookie({name: "reminder", value: "buyCoffee", minutes: 20});
deleteCookie("reminder");
An alternative - which may work for you depending on what you're trying to do - is to have the HTML in place and then use the CSS to show or hide it depending on the class of a parent element.
OR
Use jQuery append()
It's pretty straightforward with some simple rules:
then
, return it - any promise you don't return will not be waited for outside..all
them - that way it waits for all the promises and no error from any of them are silenced.then
s, you can typically return in the middle - then
chains are usually at most 1 level deep.And some tips:
.map
than with for/push
- if you're mapping values with a function, map
lets you concisely express the notion of applying actions one by one and aggregating the results.Promise.all
than to execute things one after the other - each waiting before the next.Ok, so let's get started:
var items = [1, 2, 3, 4, 5];
var fn = function asyncMultiplyBy2(v){ // sample async action
return new Promise(resolve => setTimeout(() => resolve(v * 2), 100));
};
// map over forEach since it returns
var actions = items.map(fn); // run the function over all items
// we now have a promises array and we want to wait for it
var results = Promise.all(actions); // pass array of promises
results.then(data => // or just .then(console.log)
console.log(data) // [2, 4, 6, 8, 10]
);
// we can nest this of course, as I said, `then` chains:
var res2 = Promise.all([1, 2, 3, 4, 5].map(fn)).then(
data => Promise.all(data.map(fn))
).then(function(data){
// the next `then` is executed after the promise has returned from the previous
// `then` fulfilled, in this case it's an aggregate promise because of
// the `.all`
return Promise.all(data.map(fn));
}).then(function(data){
// just for good measure
return Promise.all(data.map(fn));
});
// now to get the results:
res2.then(function(data){
console.log(data); // [16, 32, 48, 64, 80]
});

You could use startOf('day')
method to compare just the date
Example :
var dateToCompare = moment("06/04/2015 18:30:00");
var today = moment(new Date());
dateToCompare.startOf('day').isSame(today.startOf('day'));
The iterator of _.each
is called with 3 parameters (element, index, list)
. So yes, for _.each
you cab get the index.
You can do the same in sortBy
do it like this:
"abc%s" % 9
#or
"abc" + str(9)
Quick alternative
import timeit
start = timeit.default_timer()
#Your statements here
stop = timeit.default_timer()
print('Time: ', stop - start)
Basing on your solutions I've made some trick:
When you use it, your HTML will be only
<div data-keep-ratio="75%">
<div>Main content</div>
</div>
To use it this way make: CSS:
*[data-keep-ratio] {
display: block;
width: 100%;
position: relative;
}
*[data-keep-ratio] > * {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
}
and js (jQuery)
$('*[data-keep-ratio]').each(function(){
var ratio = $(this).data('keep-ratio');
$(this).css('padding-bottom', ratio);
});
And having this you just set attr data-keep-ratio
to height/width and that's it.
Here is the solution:
show full processlist;
to get the process id with status and query itself which causes the database hanging;KILL <pid>;
to kill that process.Sometimes it is not enough to kill each process manually. So, for that we've to go with some trick:
Select concat('KILL ',id,';') from information_schema.processlist where user='user';
to print all processes with KILL
command;|
sign, copy and paste all again into the query console. HIT ENTER. BooM it's done.var table = new DataTable();
using (var da = new SqlDataAdapter("SELECT * FROM mytable", "connection string"))
{
da.Fill(table);
}
The dat file has some lines of extra information before the actual data. Skip them with the skip
argument:
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)
An easy way to check this if you are unfamiliar with the dataset is to first use readLines
to check a few lines, as below:
readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
n=10)
# [1] "Ozone data from CZ03 2009" "Local time: GMT + 0"
# [3] "" "Date Hour Value"
# [5] "01.01.2009 00:00 34.3" "01.01.2009 01:00 31.9"
# [7] "01.01.2009 02:00 29.9" "01.01.2009 03:00 28.5"
# [9] "01.01.2009 04:00 32.9" "01.01.2009 05:00 20.5"
Here, we can see that the actual data starts at [4]
, so we know to skip the first three lines.
If you really only wanted the Value
column, you could do that by:
as.vector(
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)$Value)
Again, readLines
is useful for helping us figure out the actual name of the columns we will be importing.
But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

You can simply use linq
Directory.EnumerateFiles(LoanFolder).Select(file => Path.GetFileName(file));
Note: EnumeratesFiles is more efficient compared to Directory.GetFiles as you can start enumerating the collection of names before the whole collection is returned.
You better setup a single test and create a performance test from this test. This way you can monitor the progress using the default tool set.
I've always found the easiest way is php -i
and filtering down.
*nix (including MacOS):
php -i | grep "Loaded Configuration File"
Windows:
php -i | findstr /C:"Loaded Configuration File"
Of course this assumes your CLI environment is using the same PHP binaries as your actual web server.
You can always check that to be sure using which php
in *nix and where php
in Windows.
I assume we are talking about doing this in Bash?
I like to use sed to load the date values into an array so I can break down each field and do whatever I want with it. The following example assumes and input format of mm/dd/yyyy...
DATE=$2
DATE_ARRAY=(`echo $DATE | sed -e 's/\// /g'`)
MONTH=(`echo ${DATE_ARRAY[0]}`)
DAY=(`echo ${DATE_ARRAY[1]}`)
YEAR=(`echo ${DATE_ARRAY[2]}`)
LOAD_DATE=$YEAR$MONTH$DAY
you also may want to read up on the date command in linux. It can be very useful: http://unixhelp.ed.ac.uk/CGI/man-cgi?date
Hope that helps... :)

It will work if you use an IP or set domain to none. Details here:

In supported browsers, you can use the following:
.parent {
display: flex;
flex-direction: column;
}
.child {
margin-top: auto;
}
.parent {_x000D_
height: 100px;_x000D_
border: 5px solid #000;_x000D_
display: flex;_x000D_
flex-direction: column;_x000D_
}_x000D_
.child {_x000D_
height: 40px;_x000D_
width: 100%;_x000D_
background: #f00;_x000D_
margin-top: auto;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div class="child">Align to the bottom</div>_x000D_
</div>
_x000D_
The solution above is probably more flexible, however, here is an alternative solution:
.parent {
display: flex;
}
.child {
align-self: flex-end;
}
.parent {_x000D_
height: 100px;_x000D_
border: 5px solid #000;_x000D_
display: flex;_x000D_
}_x000D_
.child {_x000D_
height: 40px;_x000D_
width: 100%;_x000D_
background: #f00;_x000D_
align-self: flex-end;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div class="child">Align to the bottom</div>_x000D_
</div>
_x000D_
As a side note, you may want to add vendor prefixes for additional support.
Some version working
<div class="hidden-xs">Only Mobile hidden</div>
<div class="visible-xs">Only Mobile visible</div>
here's an example for bash:
usage="$(basename "$0") [-h] [-s n] -- program to calculate the answer to life, the universe and everything
where:
-h show this help text
-s set the seed value (default: 42)"
seed=42
while getopts ':hs:' option; do
case "$option" in
h) echo "$usage"
exit
;;
s) seed=$OPTARG
;;
:) printf "missing argument for -%s\n" "$OPTARG" >&2
echo "$usage" >&2
exit 1
;;
\?) printf "illegal option: -%s\n" "$OPTARG" >&2
echo "$usage" >&2
exit 1
;;
esac
done
shift $((OPTIND - 1))
To use this inside a function:
"$FUNCNAME"
instead of $(basename "$0")
local OPTIND OPTARG
before calling getopts
li = [0, 1, 2, 3]
for elem in li:
if (li.index(elem))+1 != len(li):
thiselem = elem
nextelem = li[li.index(elem)+1]
print 'thiselem',thiselem
print 'nextel',nextelem
else:
print 'thiselem',li[li.index(elem)]
print 'nextel',li[li.index(elem)]
In Symfony 2.6 and older versions, to get a parameter in a controller - you should get the container first, and then - the needed parameter.
$this->container->getParameter('api_user');
This documentation chapter explains it.
While $this->get()
method in a controller will load a service (doc)
In Symfony 2.7 and newer versions, to get a parameter in a controller you can use the following:
$this->getParameter('api_user');
You're looking for the JavaScriptSerializer
class, which is used internally by JsonResult:
string json = new JavaScriptSerializer().Serialize(jsonResult.Data);
On most (see details below) browsers, editing the placeholder in javascript allows multiline placeholder. As it has been said, it's not compliant with the specification and you shouldn't expect it to work in the future (edit: it does work).
This example replaces all multiline textarea's placeholder.
var textAreas = document.getElementsByTagName('textarea');
Array.prototype.forEach.call(textAreas, function(elem) {
elem.placeholder = elem.placeholder.replace(/\\n/g, '\n');
});

<textarea class="textAreaMultiline"
placeholder="Hello, \nThis is multiline example \n\nHave Fun"
rows="5" cols="35"></textarea>

Expected resultBased on comments it seems some browser accepts this hack and others don't.
This is the results of tests I ran (with browsertshots and browserstack)
Fused with theses statistics, this means that it works on about 88.7% of currently (Oct 2015) used browsers.
Update: Today, it works on at least 94.4% of currently (July 2018) used browsers.
$final_array = array_combine($a, $a);
Reference: http://php.net/array-combine
P.S. Be careful with source array containing duplicated keys like the following:
$a = ['one','two','one'];
Note the duplicated one
element.
The SQLite database engine
With library for most popular languages
This also works
String logFileName = new SimpleDateFormat("yyyyMMddHHmm'.txt'").format(new Date());
logFileName = "loggerFile_" + logFileName;
I got the top answer working (can't reply yet) after one small edit
This did not work for me:
FEATURE('authinfo','hash /etc/mail/auth/client-info')dnl
The first single quote for each string should be changed to a backtick (`) like this:
FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl
After the change I run:
sudo sendmailconfig
And I'm in business :)
Use Jquery for append the value for creating dynamically
eg:
var user_image1='<img src="{@user_image}" class="img-thumbnail" alt="Thumbnail Image"
style="width:125px; height:125px">';
$("#userphoto").append(user_image1.replace("{@user_image}","http://127.0.0.1:50075/webhdfs/v1/PATH/"+user_image+"?op=OPEN"));
HTML :
<div id="userphoto">
When entered as the reference of a Named range
, it refers to range on the sheet the named range is used on.
For example, create a named range MyName
refering to =SUM(!B1:!K1)
Place a formula on Sheet1
=MyName
. This will sum Sheet1!B1:K1
Now place the same formula (=MyName
) on Sheet2
. That formula will sum Sheet2!B1:K1
Note: (as pnuts commented) this and the regular SheetName!B1:K1
format are relative, so reference different cells as the =MyName
formula is entered into different cells.
You can define foreign key by:
public class Parent
{
public int Id { get; set; }
public virtual ICollection<Child> Childs { get; set; }
}
public class Child
{
public int Id { get; set; }
// This will be recognized as FK by NavigationPropertyNameForeignKeyDiscoveryConvention
public int ParentId { get; set; }
public virtual Parent Parent { get; set; }
}
Now ParentId is foreign key property and defines required relation between child and existing parent. Saving the child without exsiting parent will throw exception.
If your FK property name doesn't consists of the navigation property name and parent PK name you must either use ForeignKeyAttribute data annotation or fluent API to map the relation
Data annotation:
// The name of related navigation property
[ForeignKey("Parent")]
public int ParentId { get; set; }
Fluent API:
modelBuilder.Entity<Child>()
.HasRequired(c => c.Parent)
.WithMany(p => p.Childs)
.HasForeignKey(c => c.ParentId);
Other types of constraints can be enforced by data annotations and model validation.
Edit:
You will get an exception if you don't set ParentId
. It is required property (not nullable). If you just don't set it it will most probably try to send default value to the database. Default value is 0 so if you don't have customer with Id = 0 you will get an exception.
Not a true solution, but everywhere I looked the solution suggested was to simply tell Eclipse that those aren't errors. You can change it by going to Properties --> Java Compiler --> Errors Warnings --> Deprecated and restrited APIs --> Forbidden reference (acess rule), Change it from Error to Warning or Ignore.
On my Mac neither of these regular methods to uninstall Yarn worked:
brew: brew uninstall yarn
npm: npm uninstall -g yarn
Instead I removed it manually by typing rm -rf ~/.yarn
(thanks user elthrasher) and deleting the two symbol links yarn and yarnpkg from usr/local/bin
.
Afterwards brew install yarn
gave me the latest version of Yarn.
Background: The fact that I had a very outdated version of Yarn installed gave me utterly incomprehensible errors while trying to install additional modules to a project set up with Vue CLI Service and Vue UI, which apparently uses Yarn 'under the hood'. I generally use NPM so it took me a while to figure out the cause for my trouble. Naturally googling error messages produced by such module incompatibilities presented no clues. With Yarn updated everything works just perfectly now.
Yes.

If you use numpy
, this is easy:
slice = arr[:2,:2]
or if you want the 0's,
slice = arr[0:2,0:2]
You'll get the same result.
*note that slice
is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".
Another way, if you're working with lists of lists*:
slice = [arr[i][0:2] for i in range(0,2)]
(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)]
would also work.).
What I did here is that I take each desired row 1 at a time (arr[i]
). I then slice the columns I want out of that row and add it to the list that I'm building.
If you naively try: arr[0:2]
You get the first 2 rows which if you then slice again arr[0:2][0:2]
, you're just slicing the first two rows over again.
*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.
The issue is in the deserialization of the bean Customer. Your programs knows how to do it in XML, with JAXB as Daniel is writing, but most likely doesn't know how to do it in JSON.
Here you have an example with Resteasy/Jackson http://www.mkyong.com/webservices/jax-rs/integrate-jackson-with-resteasy/
The same with Jersey: http://www.mkyong.com/webservices/jax-rs/json-example-with-jersey-jackson/
Just use dynamic
as the argument:
var list = new List<dynamic>();
It is because there is no package cache in the image, you need to run:
apt-get update
before installing packages, and if your command is in a Dockerfile, you'll then need:
apt-get -y install curl
To suppress the standard output from a command use -qq
. E.g.
apt-get -qq -y install curl
A programmatic way can be to:
Note:
Answer of @r3dm4n was great. However, I needed also hour in it. Just in case someone else needed too here it is:
func formatSecondsToString(_ seconds: TimeInterval) -> String {
if seconds.isNaN {
return "00:00:00"
}
let sec = Int(seconds.truncatingRemainder(dividingBy: 60))
let min = Int(seconds.truncatingRemainder(dividingBy: 3600) / 60)
let hour = Int(seconds / 3600)
return String(format: "%02d:%02d:%02d", hour, min, sec)
}
Step 1:
Locate phpMyAdmin installation path.
Step 2:
Open phpMyAdmin>config.inc.php in your favourite text editor.
Step 3:

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
$cfg['Lang'] = '';
