From Oracle 11gR2, the LISTAGG clause should do the trick:
SELECT question_id,
LISTAGG(element_id, ',') WITHIN GROUP (ORDER BY element_id)
FROM YOUR_TABLE
GROUP BY question_id;
Beware if the resulting string is too big (more than 4000 chars for a VARCHAR2, for instance): from version 12cR2, we can use ON OVERFLOW TRUNCATE/ERROR to deal with this issue.
I was playing around with cmder (http://gooseberrycreative.com/cmder/) and I wanted to count the lines of html,css,java and javascript. While some of the answers above worked, or
pattern in grep didn't - I found here (https://unix.stackexchange.com/questions/37313/how-do-i-grep-for-multiple-patterns) that I had to escape it
So this is what I use now:
git ls-files | grep "\(.html\|.css\|.js\|.java\)$" | xargs wc -l
E:>move "blogger code.txt" d:/"blogger code.txt"
1 file(s) moved.
"blogger code.txt" is a file name
The file move from E: drive to D: drive
Generally to get the current week number (starts from Sunday):
from datetime import *
today = datetime.today()
print today.strftime("%U")
If you only have to support modern browsers, you can get away with:
You only need to convert the number to a class
, e.g. class='stars-score-50'
.

The biggest downsides of this solution are:
width
on a pseudo-element).To fix this the solution above can be easily tweaked. The :before
and :after
bits need to become actual elements in the DOM (so we need some JS for that).
The latter is left as an excercise for the reader.
You can achieve this with DateTime
extension, which will also work for number of minutes that is larger than one day (>= 1440
):
$minutes = 250;
$zero = new DateTime('@0');
$offset = new DateTime('@' . $minutes * 60);
$diff = $zero->diff($offset);
echo $diff->format('%a Days, %h Hours, %i Minutes');
Spring (nowadays) makes it easy to add Spring to a project by using just one dependency, e.g.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.1.2.RELEASE</version>
</dependency>
This will resolve to

I just shortened the answer I selected a bit:
var selectedGroups = new Array();
$("input[@name='user_group[]']:checked").each(function() {
selectedGroups.push($(this).val());
});
and it works like a charm, thanks!
When using MySQL Workbench, at Data Export, click in Advanced Options and uncheck the "lock-tables" options.
I would prefer giving him a problem and asking him to solve it using the features of .net you know and why do you think it is best solution.
This will crack almost all the capabilities of a candidate in terms of technical, analytical and problem solving skills along with his approach for solving a problem.
Another option is snprintf
:
double pi = 3.1415926;
std::string s(16, '\0');
auto written = std::snprintf(&s[0], s.size(), "%.2f", pi);
s.resize(written);
Demo. Error handling should be added, i.e. checking for written < 0
.
try this:
$('form').submit(function(){
// this function will be raised when submit button is clicked.
// perform submit operations here
});
if u r using navigation bar to change fragment then u can add change it where u r changing Fragment like below example :
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.clientsidedrawer:
// Toast.makeText(getApplicationContext(),"Client selected",Toast.LENGTH_SHORT).show();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new clients_fragment()).commit();
break;
case R.id.adddatasidedrawer:
getSupportActionBar().setTitle("Add Client");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new addclient_fragment()).commit();
break;
case R.id.editid:
getSupportActionBar().setTitle("Edit Clients");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new Editclient()).commit();
break;
case R.id.taskid:
getSupportActionBar().setTitle("Task manager");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new Taskmanager()).commit();
break;
if u r using simple activity then just call :
getSupportActionBar().setTitle("Contact Us");
to change actionbar/toolbar color in activity use :
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#06023b")));
to set gradient to actionbar first create gradient : Example directry created > R.drawable.gradient_contactus
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<gradient
android:angle="90"
android:startColor="#2980b9"
android:centerColor="#6dd5fa"
android:endColor="#2980b9">
</gradient>
</shape>
and then set it like this :
getSupportActionBar().setBackgroundDrawable(getResources().getDrawable(R.drawable.gradient_contactus));
you need external library
json-lib-2.2.2-jdk15.jar
List mybeanList = new ArrayList();
mybeanList.add("S");
mybeanList.add("b");
JSONArray jsonA = JSONArray.fromObject(mybeanList);
System.out.println(jsonA);
Google Gson is the best library http://code.google.com/p/google-gson/
In my case issue was that space
character was in the name of the source folder (Windows 10).
Here is perhaps the simplest way to obtain the value of a single cell.
document.querySelector("#table").children[0].children[r].children[c].innerText
where r is the row index and c is the column index
Therefore, to obtain all cell data and put it in a multi-dimensional array:
var tableData = [];
Array.from(document.querySelector("#table").children[0].children).forEach(function(tr){tableData.push(Array.from(tr.children).map(cell => cell.innerText))});
var cell = tableData[1][2];//2nd row, 3rd column
To access a specific cell's data in this multi-dimensional array, use the standard syntax: array[rowIndex][columnIndex].
When your native query is based on joins, in that case you can get the result as list of objects and process it.
one simple example.
@Autowired
EntityManager em;
String nativeQuery = "select name,age from users where id=?";
Query query = em.createNativeQuery(nativeQuery);
query.setParameter(1,id);
List<Object[]> list = query.getResultList();
for(Object[] q1 : list){
String name = q1[0].toString();
//..
//do something more on
}
A slightly out-of-the-box method would be to script up a solution in AutoHotKey. I use this, and it's not perfect, but works and is free. Essentially, this script assigns a hotkey to CTRL+SHIFT+R which will copy the selected SQL in SSMS (CTRL+C), save off a datestamp SQL file, and then execute the highlighted query (F5). If you aren't used to AHK scripts, the leading semicolon is a comment.
;CTRL+SHIFT+R to run a query that is first saved off
^+r::
;Copy
Send, ^c
; Set variables
EnvGet, HomeDir, USERPROFILE
FormatTime, DateString,,yyyyMMdd
FormatTime, TimeString,,hhmmss
; Make a spot to save the clipboard
FileCreateDir %HomeDir%\Documents\sqlhist\%DateString%
FileAppend, %Clipboard%, %HomeDir%\Documents\sqlhist\%DateString%\%TimeString%.sql
; execute the query
Send, {f5}
Return
The biggest limitations are that this script won't work if you click "Execute" rather than use the keyboard shortcut, and this script won't save off the whole file - just the selected text. But, you could always modify the script to execute the query, and then select all (CTRL+A) before the copy/save.
Using a modern editor with "find in files" features will let you search your SQL history. You could even get fancy and scrape your files into a SQLite3 database to query your queries.
Be sure the font is the same for all browsers. If it is the same font, then the problem has no solution using cross-browser CSS.
Because every browser has its own font rendering engine, they are all different. They can also differ in later versions, or across different OS's.
UPDATE: For those who do not understand the browser and OS font rendering differences, read this and this.
However, the difference is not even noticeable by most people, and users accept that. Forget pixel-perfect cross-browser design, unless you are:
UPDATE: I checked the example page. Tuning the kerning by text-rendering should help:
text-rendering: optimizeLegibility;
More references here:
font-smoothing
(as mentioned) and another part is text-rendering
. Tuning these properties may help as their default values are not the same across browsers.As vim's own help on set background
says, "Setting this option does not change the background color, it tells Vim what the background color looks like. For changing the background color, see |:hi-normal|."
For example
:highlight Normal ctermfg=grey ctermbg=darkblue
will write in white on blue on your color terminal.
This will do what you want:
INSERT INTO table2 (st_id,uid,changed,status,assign_status)
SELECT st_id,from_uid,now(),'Pending','Assigned'
FROM table1
If you want to include all rows from table1. Otherwise you can add a WHERE statement to the end if you want to add only a subset of table1.
I hope this helps.
Chart JS 2.0
Just set chart.data.labels = [];
For example:
function addData(chart, label, data) {
chart.data.labels.push(label);
chart.data.datasets.forEach((dataset) => {
dataset.data.push(data);
});
chart.update();
}
$chart.data.labels = [];
$.each(res.grouped, function(i,o) {
addData($chart, o.age, o.count);
});
$chart.update();
Your server configuration settings allows users to upload files upto 16MB (because you have set upload_max_filesize = 16Mb) but the post_max_size accepts post data upto 8MB only. This is why it throws an error.
Quoted from the official PHP site:
To upload large files, post_max_size value must be larger than upload_max_filesize.
memory_limit should be larger than post_max_size
You should always set your post_max_size value greater than the upload_max_filesize value.
While there isn't a standard way of doing this in ES6, there is a library called Bluebird to handle this.
There is also a recommended way described as part of the react documentation. It looks similar to what you have in your 2 and 3rd updates.
const makeCancelable = (promise) => {
let hasCanceled_ = false;
const wrappedPromise = new Promise((resolve, reject) => {
promise.then((val) =>
hasCanceled_ ? reject({isCanceled: true}) : resolve(val)
);
promise.catch((error) =>
hasCanceled_ ? reject({isCanceled: true}) : reject(error)
);
});
return {
promise: wrappedPromise,
cancel() {
hasCanceled_ = true;
},
};
};
const cancelablePromise = makeCancelable(
new Promise(r => component.setState({...}}))
);
cancelablePromise
.promise
.then(() => console.log('resolved'))
.catch((reason) => console.log('isCanceled', reason.isCanceled));
cancelablePromise.cancel(); // Cancel the promise

You can use the Boolean constants - Boolean.TRUE
and Boolean.FALSE
instead of 0
and 1
. You can create your variable as of type boolean
if primitive is what you are after. This way you won't have to create new Boolean
objects.
You can try something like:
Topic.find(:all, :conditions => ['forum_id not in (?)', @forums.map(&:id)])
You might need to do @forums.map(&:id).join(',')
. I can't remember if Rails will the argument into a CSV list if it is enumerable.
You could also do this:
# in topic.rb
named_scope :not_in_forums, lambda { |forums| { :conditions => ['forum_id not in (?)', forums.select(&:id).join(',')] }
# in your controller
Topic.not_in_forums(@forums)
The simple way is using ternary operator
var Link = React.createClass({
getInitialState: function(){
return {hover: false}
},
toggleHover: function(){
this.setState({hover: !this.state.hover})
},
render: function() {
var linkStyle;
if (this.state.hover) {
linkStyle = {backgroundColor: 'red'}
} else {
linkStyle = {backgroundColor: 'blue'}
}
return(
<div>
<a style={this.state.hover ? {"backgroundColor": 'red'}: {"backgroundColor": 'blue'}} onMouseEnter={this.toggleHover} onMouseLeave={this.toggleHover}>Link</a>
</div>
)
}
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.

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.

Can someone help me with the exact syntax?
It's a three-step process, and it involves modifying the openssl.cnf
file. You might be able to do it with only command line options, but I don't do it that way.
Find your openssl.cnf
file. It is likely located in /usr/lib/ssl/openssl.cnf
:
$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf
On my Debian system, /usr/lib/ssl/openssl.cnf
is used by the built-in openssl
program. On recent Debian systems it is located at /etc/ssl/openssl.cnf
You can determine which openssl.cnf
is being used by adding a spurious XXX
to the file and see if openssl
chokes.
First, modify the req
parameters. Add an alternate_names
section to openssl.cnf
with the names you want to use. There are no existing alternate_names
sections, so it does not matter where you add it.
[ alternate_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = mail.example.com
DNS.4 = ftp.example.com
Next, add the following to the existing [ v3_ca ]
section. Search for the exact string [ v3_ca ]
:
subjectAltName = @alternate_names
You might change keyUsage
to the following under [ v3_ca ]
:
keyUsage = digitalSignature, keyEncipherment
digitalSignature
and keyEncipherment
are standard fare for a server certificate. Don't worry about nonRepudiation
. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.
In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.
Second, modify the signing parameters. Find this line under the CA_default
section:
# Extension copying option: use with caution.
# copy_extensions = copy
And change it to:
# Extension copying option: use with caution.
copy_extensions = copy
This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.
Third, generate your self-signed certificate:
$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...
Finally, examine the certificate:
$ openssl x509 -in certificate.pem -text -noout

Lalith's answer is correct.
You may also try this approach:
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
invalidateOptionsMenu();
}
});
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
MenuItem settingsItem = menu.findItem(R.id.action_settings);
// set your desired icon here based on a flag if you like
settingsItem.setIcon(ContextCompat.getDrawable(this, R.drawable.ic_launcher));
return super.onPrepareOptionsMenu(menu);
}
If you want to use the catch()
of the Observable
you need to use Observable.throw()
method before delegating the error response to a method

ALTER USER
Example:
ALTER USER 'username' IDENTIFIED BY 'password';
Because:
SET PASSWORD ... = PASSWORD('auth_string')
syntax is deprecated as of MySQL 5.7.6 and will be removed in a future MySQL release.
SET PASSWORD ... = 'auth_string'
syntax is not deprecated, but ALTER USER
is now the preferred statement for assigning passwords.

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?
You could check in the following way (extra = and making length a truthy evaluation)
if (typeof(sub.from) !== 'undefined' && sub.from.length) {
[update]
I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:
for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
mainid = sub.from[i]['id'];
var sub = afcHelper_Submissions[mainid]; // <== re setting sub
My guess is that the error is not on the if statement but on the for(i...
statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).
I have create an extension method based on position of items in a list which is bind with recycler view
Smooth scroll in large list takes longer time to scroll , use this to improve speed of scrolling and also have the smooth scroll animation. Cheers!!
fun RecyclerView?.perfectScroll(size: Int,up:Boolean = true ,smooth: Boolean = true) {
this?.apply {
if (size > 0) {
if (smooth) {
val minDirectScroll = 10 // left item to scroll
//smooth scroll
if (size > minDirectScroll) {
//scroll directly to certain position
val newSize = if (up) minDirectScroll else size - minDirectScroll
//scroll to new position
val newPos = newSize - 1
//direct scroll
scrollToPosition(newPos)
//smooth scroll to rest
perfectScroll(minDirectScroll, true)
} else {
//direct smooth scroll
smoothScrollToPosition(if (up) 0 else size-1)
}
} else {
//direct scroll
scrollToPosition(if (up) 0 else size-1)
}
}
} }
Just call the method anywhere using
rvList.perfectScroll(list.size,up=true,smooth=true)
In JS "==" sign does not check the type of variable. Therefore, "0" = 0 = false (in JS 0 = false) and will return true in this case, but if you use "===" the result will be false.
When you use "if", it will be "false" in the following case:
[0, false, '', null, undefined, NaN] // null = undefined, 0 = false
So
if("0") = if( ("0" !== 0) && ("0" !== false) && ("0" !== "") && ("0" !== null) && ("0" !== undefined) && ("0" !== NaN) )
= if(true && true && true && true && true && true)
= if(true)
//CSS:

Search for "Objective-C Generated Interface Header Name" in the Build Settings of the target you're trying to build (let's say it's MyApp-Swift.h
), and import the value of this setting (#import "MyApp-Swift.h"
) in the source file where you're trying to access your Swift APIs.
The default value for this field is $(SWIFT_MODULE_NAME)-Swift.h
. You can see it if you double-click in the value field of the "Objective-C Generated Interface Header Name" setting.
Also, if you have dashes in your module name (let's say it's My-App
), then in the $(SWIFT_MODULE_NAME)
all dashes will be replaced with underscores. So then you'll have to add #import "My_App-Swift.h"
.
I think I can illustrate this quite nicely. Since nextTick
is called at the end of the current operation, calling it recursively can end up blocking the event loop from continuing. setImmediate
solves this by firing in the check phase of the event loop, allowing event loop to continue normally.

source: https://nodejs.org/en/docs/guides/event-loop-timers-and-nexttick/
Notice that the check phase is immediately after the poll phase. This is because the poll phase and I/O callbacks are the most likely places your calls to setImmediate
are going to run. So ideally most of those calls will actually be pretty immediate, just not as immediate as nextTick
which is checked after every operation and technically exists outside of the event loop.
Let's take a look at a little example of the difference between setImmediate
and process.nextTick
:
function step(iteration) {
if (iteration === 10) return;
setImmediate(() => {
console.log(`setImmediate iteration: ${iteration}`);
step(iteration + 1); // Recursive call from setImmediate handler.
});
process.nextTick(() => {
console.log(`nextTick iteration: ${iteration}`);
});
}
step(0);
Let's say we just ran this program and are stepping through the first iteration of the event loop. It will call into the step
function with iteration zero. It will then register two handlers, one for setImmediate
and one for process.nextTick
. We then recursively call this function from the setImmediate
handler which will run in the next check phase. The nextTick
handler will run at the end of the current operation interrupting the event loop, so even though it was registered second it will actually run first.
The order ends up being: nextTick
fires as current operation ends, next event loop begins, normal event loop phases execute, setImmediate
fires and recursively calls our step
function to start the process all over again. Current operation ends, nextTick
fires, etc.
The output of the above code would be:
nextTick iteration: 0
setImmediate iteration: 0
nextTick iteration: 1
setImmediate iteration: 1
nextTick iteration: 2
setImmediate iteration: 2
nextTick iteration: 3
setImmediate iteration: 3
nextTick iteration: 4
setImmediate iteration: 4
nextTick iteration: 5
setImmediate iteration: 5
nextTick iteration: 6
setImmediate iteration: 6
nextTick iteration: 7
setImmediate iteration: 7
nextTick iteration: 8
setImmediate iteration: 8
nextTick iteration: 9
setImmediate iteration: 9
Now let's move our recursive call to step
into our nextTick
handler instead of the setImmediate
.
function step(iteration) {
if (iteration === 10) return;
setImmediate(() => {
console.log(`setImmediate iteration: ${iteration}`);
});
process.nextTick(() => {
console.log(`nextTick iteration: ${iteration}`);
step(iteration + 1); // Recursive call from nextTick handler.
});
}
step(0);
Now that we have moved the recursive call to step
into the nextTick
handler things will behave in a different order. Our first iteration of the event loop runs and calls step
registering a setImmedaite
handler as well as a nextTick
handler. After the current operation ends our nextTick
handler fires which recursively calls step
and registers another setImmediate
handler as well as another nextTick
handler. Since a nextTick
handler fires after the current operation, registering a nextTick
handler within a nextTick
handler will cause the second handler to run immediately after the current handler operation finishes. The nextTick
handlers will keep firing, preventing the current event loop from ever continuing. We will get through all our nextTick
handlers before we see a single setImmediate
handler fire.
The output of the above code ends up being:
nextTick iteration: 0
nextTick iteration: 1
nextTick iteration: 2
nextTick iteration: 3
nextTick iteration: 4
nextTick iteration: 5
nextTick iteration: 6
nextTick iteration: 7
nextTick iteration: 8
nextTick iteration: 9
setImmediate iteration: 0
setImmediate iteration: 1
setImmediate iteration: 2
setImmediate iteration: 3
setImmediate iteration: 4
setImmediate iteration: 5
setImmediate iteration: 6
setImmediate iteration: 7
setImmediate iteration: 8
setImmediate iteration: 9
Note that had we not interrupted the recursive call and aborted it after 10 iterations then the nextTick
calls would keep recursing and never letting the event loop continue to the next phase. This is how nextTick
can become blocking when used recursively whereas setImmediate
will fire in the next event loop and setting another setImmediate
handler from within one won't interrupt the current event loop at all, allowing it to continue executing phases of the event loop as normal.
Hope that helps!
PS - I agree with other commenters that the names of the two functions could easily be swapped since nextTick
sounds like it's going to fire in the next event loop rather than the end of the current one, and the end of the current loop is more "immediate" than the beginning of the next loop. Oh well, that's what we get as an API matures and people come to depend on existing interfaces.
For Kotlin use KTX extension function:

you can pass multiple params in url like
http://localhost:2000/custom?brand=dell&limit=20&price=20000&sort=asc
and in order to get this query fields , you can use map like
@RequestMapping(method = RequestMethod.GET, value = "/custom")
public String controllerMethod(@RequestParam Map<String, String> customQuery) {
System.out.println("customQuery = brand " + customQuery.containsKey("brand"));
System.out.println("customQuery = limit " + customQuery.containsKey("limit"));
System.out.println("customQuery = price " + customQuery.containsKey("price"));
System.out.println("customQuery = other " + customQuery.containsKey("other"));
System.out.println("customQuery = sort " + customQuery.containsKey("sort"));
return customQuery.toString();
}
You can use sys.exit()
to exit from the middle of the main function.
However, I would recommend not doing any logic there. Instead, put everything in a function, and call that from __main__
- then you can use return as normal.
You can use below code to get all the privileges list from all users.
select * from dba_sys_privs
In the end, I right-clicked on the certificate, and selected "Get Info". Under the Trust section, I selected "Always Trust" and this solved my problem.

Using Yoo's answer, put this in your ~/.bashrc
:
sudoe() {
[[ "$#" -ne 2 ]] && echo "Usage: sudoe <text> <file>" && return 1
echo "$1" | sudo tee --append "$2" > /dev/null
}
Now you can run sudoe 'deb blah # blah' /etc/apt/sources.list
Edit:
A more complete version which allows you to pipe input in or redirect from a file and includes a -a
switch to turn off appending (which is on by default):
sudoe() {
if ([[ "$1" == "-a" ]] || [[ "$1" == "--no-append" ]]); then
shift &>/dev/null || local failed=1
else
local append="--append"
fi
while [[ $failed -ne 1 ]]; do
if [[ -t 0 ]]; then
text="$1"; shift &>/dev/null || break
else
text="$(cat <&0)"
fi
[[ -z "$1" ]] && break
echo "$text" | sudo tee $append "$1" >/dev/null; return $?
done
echo "Usage: $0 [-a|--no-append] [text] <file>"; return 1

The recent openssh version deprecated DSA keys by default. You should suggest to your GIT provider to add some reasonable host key. Relying only on DSA is not a good idea.
As a workaround, you need to tell your ssh
client that you want to accept DSA host keys, as described in the official documentation for legacy usage. You have few possibilities, but I recommend to add these lines into your ~/.ssh/config
file:
Host your-remote-host
HostkeyAlgorithms +ssh-dss
Other possibility is to use environment variable GIT_SSH
to specify these options:
GIT_SSH_COMMAND="ssh -oHostKeyAlgorithms=+ssh-dss" git clone ssh://user@host/path-to-repository
I use this code piece while working with indexes for radio group:
radioGroup.check(radioGroup.getChildAt(index).getId());
Probably you haven't injected $http
service to your controller. There are several ways of doing that.
Please read this reference about DI. Then it gets very simple:
function MyController($scope, $http) {
// ... your code
}
The return statements should place in one line. Or the other option is to remove the curly brackets that bound the HTML statement.
example:
return posts.map((post, index) =>
<div key={index}>
<h3>{post.title}</h3>
<p>{post.body}</p>
</div>
);
You can add a simple css3 rule in the body or in specific div, use pointer-events: none;
property.
cd /usr/local && sudo chown -R $(whoami) bin etc include lib sbin share var opt Cellar Frameworks
fs.exists() is deprecated dont use it https://nodejs.org/api/fs.html#fs_fs_exists_path_callback
You could implement the core nodejs way used at this: https://github.com/nodejs/node-v0.x-archive/blob/master/lib/module.js#L86
function statPath(path) {
try {
return fs.statSync(path);
} catch (ex) {}
return false;
}
this will return the stats object then once you've got the stats object you could try
var exist = statPath('/path/to/your/file.js');
if(exist && exist.isFile()) {
// do something
}
Element.insertAdjacentHTML has very good browser support, and can add a stylesheet in one line.

Building on Preet Sangha's solution, the following should safely cover the scenario where you're working with a large solution with the potential for several Inner Exceptions.
try
{
object result = processClass.InvokeMethod("Create", methodArgs);
}
catch (Exception e)
{
// Here I was hoping to get an error code.
if (ExceptionContainsErrorCode(e, 10004))
{
// Execute desired actions
}
}
...
private bool ExceptionContainsErrorCode(Exception e, int ErrorCode)
{
Win32Exception winEx = e as Win32Exception;
if (winEx != null && ErrorCode == winEx.ErrorCode)
return true;
if (e.InnerException != null)
return ExceptionContainsErrorCode(e.InnerException, ErrorCode);
return false;
}
This code has been unit tested.
I won't harp too much on the need for coming to appreciate and implement good practice when it comes to Exception Handling by managing each expected Exception Type within their own blocks.

Use the TRIM SQL function.
If you are using SQL Server try :
SELECT LTRIM(RTRIM(YourColumn)) FROM YourTable
tl;dr:
ContextCompat.getColor(context, R.color.my_color)
Explanation:
You will need to use ContextCompat.getColor(), which is part of the Support V4 Library (it will work for all the previous APIs).
ContextCompat.getColor(context, R.color.my_color)
If you don't already use the Support Library, you will need to add the following line to the dependencies
array inside your app build.gradle
(note: it's optional if you already use the appcompat (V7) library):
compile 'com.android.support:support-v4:23.0.0' # or any version above
If you care about themes, the documentation specifies that:
Starting in M, the returned color will be styled for the specified Context's theme
You can use --jars $(echo /Path/To/Your/Jars/*.jar | tr ' ' ',') to include entire folder of Jars. So, spark-submit -- class com.yourClass \ --jars $(echo /Path/To/Your/Jars/*.jar | tr ' ' ',') \ ...
I solved it this way (similar to above but I feel like it's a cleaner solution) Works with .NET Core 3.x
Create MappingProfile.cs class and populate constructor with Maps (I plan on using a single class to hold all my mappings)
public class MappingProfile : Profile
{
public MappingProfile()
{
CreateMap<Source, Dest>().ReverseMap();
}
}
In Startup.cs, add below to add to DI (the assembly arg is for the class that holds your mapping configs, in my case, it's the MappingProfile class).
//add automapper DI
services.AddAutoMapper(typeof(MappingProfile));
In Controller, use it like you would any other DI object
[Route("api/[controller]")]
[ApiController]
public class AnyController : ControllerBase
{
private readonly IMapper _mapper;
public AnyController(IMapper mapper)
{
_mapper = mapper;
}
public IActionResult Get(int id)
{
var entity = repository.Get(id);
var dto = _mapper.Map<Dest>(entity);
return Ok(dto);
}
}
The only software that I found that already exists is Matrox PowerDesk. Among other things it lets you split a monitor into 2 virtual desktops. You have to have a compatible matrox video card though. It also does a bunch of other multi-monitor functions.
You can create an alias for it. I am using ZSH shell with Oh-my-Zsh and here is an handy alias:
# delete and re-init git
# usage: just type 'gdelinit' in a local repository
alias gdelinit="trash .git && git init"
I am using Trash to trash the .git
folder since using rm
is really dangerous:
trash .git
Then I am re-initializing the git repo:
git init
Also with option -T

As of October 2014, you can just do something like the following (using JSONStream) - https://www.npmjs.org/package/JSONStream
var fs = require('fs'),
JSONStream = require('JSONStream'),
var getStream() = function () {
var jsonData = 'myData.json',
stream = fs.createReadStream(jsonData, { encoding: 'utf8' }),
parser = JSONStream.parse('*');
return stream.pipe(parser);
}
getStream().pipe(MyTransformToDoWhateverProcessingAsNeeded).on('error', function (err) {
// handle any errors
});
To demonstrate with a working example:
npm install JSONStream event-stream
data.json:
{
"greeting": "hello world"
}
hello.js:
var fs = require('fs'),
JSONStream = require('JSONStream'),
es = require('event-stream');
var getStream = function () {
var jsonData = 'data.json',
stream = fs.createReadStream(jsonData, { encoding: 'utf8' }),
parser = JSONStream.parse('*');
return stream.pipe(parser);
};
getStream()
.pipe(es.mapSync(function (data) {
console.log(data);
}));
$ node hello.js
// hello world
None of these responses really seem to answer the question. Here's something similar to what I'm utilizing on a site of mine by targeting a menu item by its title/name:
function add_class_to_menu_item($sorted_menu_objects, $args) {
$theme_location = 'primary_menu'; // Name, ID, or Slug of the target menu location
$target_menu_title = 'Link'; // Name/Title of the menu item you want to target
$class_to_add = 'my_own_class'; // Class you want to add
if ($args->theme_location == $theme_location) {
foreach ($sorted_menu_objects as $key => $menu_object) {
if ($menu_object->title == $target_menu_title) {
$menu_object->classes[] = $class_to_add;
break; // Optional. Leave if you're only targeting one specific menu item
}
}
}
return $sorted_menu_objects;
}
add_filter('wp_nav_menu_objects', 'add_class_to_menu_item', 10, 2);
Check if have not set a open_basedir in php.ini or .htaccess of domain what you use. That will jail you in directory of your domain and php will get only access to execute inside this directory.
As others answers are correct, but too simple, so for completeness I'm presenting below code snippet to perform SELECT COUNT
on a sophisticated JPA Criteria query (with multiple joins, fetches, conditions).
It is slightly modified this answer.
public <T> long count(final CriteriaBuilder cb, final CriteriaQuery<T> selectQuery,
Root<T> root) {
CriteriaQuery<Long> query = createCountQuery(cb, selectQuery, root);
return this.entityManager.createQuery(query).getSingleResult();
}
private <T> CriteriaQuery<Long> createCountQuery(final CriteriaBuilder cb,
final CriteriaQuery<T> criteria, final Root<T> root) {
final CriteriaQuery<Long> countQuery = cb.createQuery(Long.class);
final Root<T> countRoot = countQuery.from(criteria.getResultType());
doJoins(root.getJoins(), countRoot);
doJoinsOnFetches(root.getFetches(), countRoot);
countQuery.select(cb.count(countRoot));
countQuery.where(criteria.getRestriction());
countRoot.alias(root.getAlias());
return countQuery.distinct(criteria.isDistinct());
}
@SuppressWarnings("unchecked")
private void doJoinsOnFetches(Set<? extends Fetch<?, ?>> joins, Root<?> root) {
doJoins((Set<? extends Join<?, ?>>) joins, root);
}
private void doJoins(Set<? extends Join<?, ?>> joins, Root<?> root) {
for (Join<?, ?> join : joins) {
Join<?, ?> joined = root.join(join.getAttribute().getName(), join.getJoinType());
joined.alias(join.getAlias());
doJoins(join.getJoins(), joined);
}
}
private void doJoins(Set<? extends Join<?, ?>> joins, Join<?, ?> root) {
for (Join<?, ?> join : joins) {
Join<?, ?> joined = root.join(join.getAttribute().getName(), join.getJoinType());
joined.alias(join.getAlias());
doJoins(join.getJoins(), joined);
}
}
Hope it saves somebody's time.
Because IMHO JPA Criteria API is not intuitive nor quite readable.
For linuxes I've figured out that ECU could be measured by sysbench:
sysbench --num-threads=128 --test=cpu --cpu-max-prime=50000 --max-requests=50000 run
Total time (t) should be calculated by formula:
ECU=1925/t
And my example test results:
| instance type | time | ECU |
|-------------------|----------|---------|
| m1.small | 1735,62 | 1 |
| m3.xlarge | 147,62 | 13 |
| m3.2xlarge | 74,61 | 26 |
| r3.large | 295,84 | 7 |
| r3.xlarge | 148,18 | 13 |
| m4.xlarge | 146,71 | 13 |
| m4.2xlarge | 73,69 | 26 |
| c4.xlarge | 123,59 | 16 |
| c4.2xlarge | 61,91 | 31 |
| c4.4xlarge | 31,14 | 62 |
Avoid loops. What you want to do is:
import numpy as np
data=np.loadtxt(fname="data.txt")## to load the above two column
print data
print data.sum(axis=1)

All of the answers didn't work for me, I checked the playlist URL and seen that playlist parameter changed to list! So it should be:
&loop=1&list=PLvNxGp1V1dOwpDBl7L3AJIlkKYdNDKUEs
So here is the full code I use make a clean, looping, autoplay video:
<iframe width="100%" height="425" src="https://www.youtube.com/embed/MavEpJETfgI?autoplay=1&showinfo=0&loop=1&list=PLvNxGp1V1dOwpDBl7L3AJIlkKYdNDKUEs&rel=0" frameborder="0" allowfullscreen></iframe>
that syntax is now deprecated, you will get this error:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 14: Expected a stage @ line 14, column 9.
parallel firstTask: {
^
WorkflowScript: 14: Stage does not have a name @ line 14, column 9.
parallel secondTask: {
^
2 errors
You should do something like:
stage("Parallel") {
steps {
parallel (
"firstTask" : {
//do some stuff
},
"secondTask" : {
// Do some other stuff in parallel
}
)
}
}
Just to add the use of node here, to distribute jobs across multiple build servers/ VMs:
pipeline {
stages {
stage("Work 1"){
steps{
parallel ( "Build common Library":
{
node('<Label>'){
/// your stuff
}
},
"Build Utilities" : {
node('<Label>'){
/// your stuff
}
}
)
}
}
All VMs should be labelled as to use as a pool.
response.statusCode
is a number, e.g. response.statusCode === 200
, not '200'
. As the error message says, write
expects a string
or Buffer
object, so you must convert it.
res.write(response.statusCode.toString());
You are also correct about your callback comment though. res.end();
should be inside the callback, just below your write
calls.
Similar to the first example, but with more flexibility:
-- min_length = 8, max_length = 12
SET @Length = RAND() * 5 + 8
-- SET @Length = RAND() * (max_length - min_length + 1) + min_length
-- define allowable character explicitly - easy to read this way an easy to
-- omit easily confused chars like l (ell) and 1 (one) or 0 (zero) and O (oh)
SET @CharPool =
'abcdefghijkmnopqrstuvwxyzABCDEFGHIJKLMNPQRSTUVWXYZ23456789.,-_!$@#%^&*'
SET @PoolLength = Len(@CharPool)
SET @LoopCount = 0
SET @RandomString = ''
WHILE (@LoopCount < @Length) BEGIN
SELECT @RandomString = @RandomString +
SUBSTRING(@Charpool, CONVERT(int, RAND() * @PoolLength) + 1, 1)
SELECT @LoopCount = @LoopCount + 1
END
I forgot to mention one of the other features that makes this more flexible. By repeating blocks of characters in @CharPool, you can increase the weighting on certain characters so that they are more likely to be chosen.

If you want to pull down a remote branch to run locally (say for reviewing or testing purposes), and when you $ git pull
you get local merge conflicts:
$ git checkout REMOTE-BRANCH
$ git pull (you get local merge conflicts)
$ git reset --hard HEAD (discards local conflicts, and resets to remote branch HEAD)
$ git pull (now get remote branch updates without local conflicts)

data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]
plt.subplots_adjust(bottom = 0.1)
plt.scatter(

But to fix it, knowing you are the only one changing it, do:
1 - backup your project (I did only the files on git, ./src folder)
2 - git pull
3 - restore you backup over the many "messed" files (with merge indicators)
I tried git pull -s recursive -X ours
but didnt work the way I wanted, it could be an option tho, but backup first!!!
Make sure the differences/changes (at git gui) are none. This is my case, there is nothing to merge at all, but github keeps saying I should merge...
If you really don't like the Terminal here is the GUI way to do dkamins is telling you :
1) Go to your user home directory (ludo would be mine) and from the File menu choose Get Info cmdI in the inspector :
2) By alt/option clicking on the [+] sign add the _www group and set it's permission to read-only :
3) Show the Get Info inspector of your user Sites folder and reproduce step 2 then from the gear action sub-menu choose Apply to enclosed Items... :
Voilà 3 steps and the GUI only way...
I see that BigDecimal has an inflate() method on equals() method. What does inflate() do actually?
Basically, inflate()
calls BigInteger.valueOf(intCompact)
if necessary, i.e. it creates the unscaled value that is stored as a BigInteger
from long intCompact
. If you don't need that BigInteger
and the unscaled value fits into a long
BigDecimal
seems to try to save space as long as possible.
After allocating DateFormatter
you need to give the formatted string
then you can convert as string like this way
var date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let myString = formatter.string(from: date)
let yourDate: Date? = formatter.date(from: myString)
formatter.dateFormat = "dd-MMM-yyyy"
let updatedString = formatter.string(from: yourDate!)
print(updatedString)

ES6 introduce template strings for concatenation. Template Strings use back-ticks (``) rather than the single or double quotes we're used to with regular strings. A template string could thus be written as follows:
// Simple string substitution
let name = "Brendan";
console.log(`Yo, ${name}!`);
// => "Yo, Brendan!"
var a = 10;
var b = 10;
console.log(`JavaScript first appeared ${a+b} years ago. Crazy!`);
//=> JavaScript first appeared 20 years ago. Crazy!

Directory.GetParent
is probably a better answer, but for completeness there's a different method that takes string and returns string: Path.GetDirectoryName
.
string parent = System.IO.Path.GetDirectoryName(str_directory);
string = string.replace(/[\W_]/g, "_");
The last update for "windows git" did move the git.exe file from the /bin folder to the /cmd folder. So, to use git with IDEs such as webStorm or Android Studio you can use the path :
C:\Users\<user>\AppData\Local\GitHub\PortableGit_<..numbers..>\cmd\git.exe
But if you want to have linux-like commands such as git, ssh, ls, cp under windows powerShell or cmd add to your windows PATH variables :
C:\Users\<user>\AppData\Local\GitHub\PortableGit_<...numbers...>\usr\bin
change <user> and <...numbers...> to your values and reboot!
Also, you will have to update this everytime git updates since it might change the portable folder name. If folder structure changes I will update this post.
Thx @dennisschagt for the comment above! ;)

Shutdown Hooks are unstarted threads that are registered with Runtime.addShutdownHook().JVM does not give any guarantee on the order in which shutdown hooks are started.For more info refer http://techno-terminal.blogspot.in/2015/08/shutdown-hooks.html
Double equals ==
will always check based on object identity, regardless of the objects' implementation of hashCode or equals. Of course - make sure the object references you are comparing are volatile
(in a 1.5+ JVM).
If you really must have the original Object toString result (although it's not the best solution for your example use-case), the Commons Lang library has a method ObjectUtils.identityToString(Object) that will do what you want. From the JavaDoc:
public static java.lang.String identityToString(java.lang.Object object)
Gets the toString that would be produced by Object if a class did not override toString itself. null will return null.
ObjectUtils.identityToString(null) = null
ObjectUtils.identityToString("") = "java.lang.String@1e23"
ObjectUtils.identityToString(Boolean.TRUE) = "java.lang.Boolean@7fa"
Use the CREATE TABLE SELECT syntax.

CREATE TABLE new_tbl SELECT * FROM orig_tbl;
As long as method parameters (number (or) type) are different, yes they can. It is called overloading.
Overloaded methods are differentiated by the number and the type of the arguments passed into the method
public static void main(String[] args)
only main method with single String[]
(or) String...
as param will be considered as entry point for the program.
The distribute
package provides a Python 3-compatible version of setuptools
: http://pypi.python.org/pypi/distribute
Also, use pip
to install the modules. It automatically finds dependencies and installs them for you.
It works just fine for me with your package:
[~] pip --version
pip 1.2.1 from /usr/lib/python3.3/site-packages (python 3.3)
[~] sudo pip install ansicolors

You (normally) cannot modify the collection you are iterating over when using foreach.
Although for and foreach seem to be similar from a developer perspective they are quite different from an implementation perspective.
Foreach
uses an Iterator
to access the individual objects while for
doesn't know (or care) about the underlying object sequence.
Android 4.4 (Kit Kat) does have a new sniffing capability for Bluetooth. You should give it a try.
If you don’t own a sniffing device however, you aren’t necessarily out of luck. In many cases we can obtain positive results with a new feature introduced in Android 4.4: the ability to capture all Bluetooth HCI packets and save them to a file.
When the Analyst has finished populating the capture file by running the application being tested, he can pull the file generated by Android into the external storage of the device and analyze it (with Wireshark, for example).
Once this setting is activated, Android will save the packet capture to /sdcard/btsnoop_hci.log to be pulled by the analyst and inspected.
Type the following in case /sdcard/
is not the right path on your particular device:
adb shell echo \$EXTERNAL_STORAGE
We can then open a shell and pull the file: $adb pull /sdcard/btsnoop_hci.log and inspect it with Wireshark, just like a PCAP collected by sniffing WiFi traffic for example, so it is very simple and well supported:
You can enable this by going to Settings->Developer Options, then checking the box next to "Bluetooth HCI Snoop Log."
Looking into https://mochajs.org/#usage we see that simply use
mocha test/myfile
will work. You can omit the '.js' at the end.

In most cases, this error is the result of code which tries to instantiate a COM object. For example, here is a piece of code starting up Excel:
Excel.ApplicationClass xlapp = new Excel.ApplicationClass();
Typically, in .NET 4 you just need to remove the 'Class' suffix and compile the code:
Excel.Application xlapp = new Excel.Application();
An MSDN explanation is here.
But how does this handle language specific sorting rules? Does it take locale into account?
No, list.sort()
is a generic sorting function. If you want to sort according to the Unicode rules, you'll have to define a custom sort key function. You can try using the pyuca module, but I don't know how complete it is.
show user
to get connected user
select instance_name from v$instance
to get instance or set in sqlplus
set sqlprompt "_USER'@'_CONNECT_IDENTIFIER> "
put the logic in
afterTextChanged(Editable s) {
string str = s.toString()
// use the string str
}
The simple answer is, whenever an operation is impossible (because of either application OR because it would violate business logic). If a method is invoked and it impossible to do what the method was written to do, throw an Exception. A good example is that constructors always throw ArgumentExceptions if an instance cannot be created using the supplied parameters. Another example is InvalidOperationException, which is thrown when an operation cannot be performed because of the state of another member or members of the class.
In your case, if a method like Login(username, password) is invoked, if the username is not valid, it is indeed correct to throw a UserNameNotValidException, or PasswordNotCorrectException if password is incorrect. The user cannot be logged in using the supplied parameter(s) (i.e. it's impossible because it would violate authentication), so throw an Exception. Although I might have your two Exceptions inherit from ArgumentException.
Having said that, if you wish NOT to throw an Exception because a login failure may be very common, one strategy is to instead create a method that returns types that represent different failures. Here's an example:
{ // class
...
public LoginResult Login(string user, string password)
{
if (IsInvalidUser(user))
{
return new UserInvalidLoginResult(user);
}
else if (IsInvalidPassword(user, password))
{
return new PasswordInvalidLoginResult(user, password);
}
else
{
return new SuccessfulLoginResult();
}
}
...
}
public abstract class LoginResult
{
public readonly string Message;
protected LoginResult(string message)
{
this.Message = message;
}
}
public class SuccessfulLoginResult : LoginResult
{
public SucccessfulLogin(string user)
: base(string.Format("Login for user '{0}' was successful.", user))
{ }
}
public class UserInvalidLoginResult : LoginResult
{
public UserInvalidLoginResult(string user)
: base(string.Format("The username '{0}' is invalid.", user))
{ }
}
public class PasswordInvalidLoginResult : LoginResult
{
public PasswordInvalidLoginResult(string password, string user)
: base(string.Format("The password '{0}' for username '{0}' is invalid.", password, user))
{ }
}
Most developers are taught to avoid Exceptions because of the overhead caused by throwing them. It's great to be resource-conscious, but usually not at the expense of your application design. That is probably the reason you were told not to throw your two Exceptions. Whether to use Exceptions or not usually boils down to how frequently the Exception will occur. If it's a fairly common or an fairly expectable result, this is when most developers will avoid Exceptions and instead create another method to indicate failure, because of the supposed consumption of resources.
Here's an example of avoiding using Exceptions in a scenario like just described, using the Try() pattern:
public class ValidatedLogin
{
public readonly string User;
public readonly string Password;
public ValidatedLogin(string user, string password)
{
if (IsInvalidUser(user))
{
throw new UserInvalidException(user);
}
else if (IsInvalidPassword(user, password))
{
throw new PasswordInvalidException(password);
}
this.User = user;
this.Password = password;
}
public static bool TryCreate(string user, string password, out ValidatedLogin validatedLogin)
{
if (IsInvalidUser(user) ||
IsInvalidPassword(user, password))
{
return false;
}
validatedLogin = new ValidatedLogin(user, password);
return true;
}
}
You use new
to perform dynamic allocation. It returns a pointer that points to the dynamically allocated object.
You have no reason to use new
, since A
is an automatic variable. You can simply initialise A
using its constructor:
vector<vector<int> > A(dimension, vector<int>(dimension));
Recently discovered that a third party library - Square Retrofit can do the job very well.
Defining REST endpoint
public interface GitHubService {
@GET("/users/{user}/repos")
List<Repo> listRepos(@Path("user") String user,Callback<List<User>> cb);
}
Getting the concrete service
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("https://api.github.com")
.build();
GitHubService service = restAdapter.create(GitHubService.class);
Calling the REST endpoint
List<Repo> repos = service.listRepos("octocat",new Callback<List<User>>() {
@Override
public void failure(final RetrofitError error) {
android.util.Log.i("example", "Error, body: " + error.getBody().toString());
}
@Override
public void success(List<User> users, Response response) {
// Do something with the List of Users object returned
// you may populate your adapter here
}
});
The library handles the json serialization and deserailization for you. You may customize the serialization and deserialization too.
Gson gson = new GsonBuilder()
.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
.registerTypeAdapter(Date.class, new DateTypeAdapter())
.create();
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("https://api.github.com")
.setConverter(new GsonConverter(gson))
.build();
I did some test to see how the theory actually works: kennethxu.blogspot.com/2009/05/interlocked-vs-monitor-performance.html. My test was more focused on CompareExchnage but the result for Increment is similar. Interlocked is not necessary faster in multi-cpu environment. Here is the test result for Increment on a 2 years old 16 CPU server. Bare in mind that the test also involves the safe read after increase, which is typical in real world.

Here's your code with a few fixes, it prints out only primes:
import math
def main():
count = 3
while True:
isprime = True
for x in range(2, int(math.sqrt(count) + 1)):
if count % x == 0:
isprime = False
break
if isprime:
print count
count += 1
For much more efficient prime generation, see the Sieve of Eratosthenes, as others have suggested. Here's a nice, optimized implementation with many comments:
# Sieve of Eratosthenes
# Code by David Eppstein, UC Irvine, 28 Feb 2002
# http://code.activestate.com/recipes/117119/
def gen_primes():
""" Generate an infinite sequence of prime numbers.
"""
# Maps composites to primes witnessing their compositeness.
# This is memory efficient, as the sieve is not "run forward"
# indefinitely, but only as long as required by the current
# number being tested.
#
D = {}
# The running integer that's checked for primeness
q = 2
while True:
if q not in D:
# q is a new prime.
# Yield it and mark its first multiple that isn't
# already marked in previous iterations
#
yield q
D[q * q] = [q]
else:
# q is composite. D[q] is the list of primes that
# divide it. Since we've reached q, we no longer
# need it in the map, but we'll mark the next
# multiples of its witnesses to prepare for larger
# numbers
#
for p in D[q]:
D.setdefault(p + q, []).append(p)
del D[q]
q += 1
Note that it returns a generator.
1. Check for your configuration files by running the aforementioned command: sudo nginx -t
.
2. Check for port conflicts. For instance, if apache2 (ps waux | grep apache2
) or any other service is using the same ports configured for nginx (say port 80) the service will not start and will fail silently (err... the cousin of my friend had this problem...)
If you're looking for a shortcut for writing out all of your selectors, then a CSS Preprocessor (Sass, LESS, Stylus, etc.) can do what you're looking for. However, the generated styles must be valid CSS.
Sass:
#applyCSS {
.ui-bar-a {
color: blue;
}
.ui-bar-a .ui-link-inherit {
color: orange;
}
background: #CCC;
}
Generated CSS:
#applyCSS {
background: #CCC;
}
#applyCSS .ui-bar-a {
color: blue;
}
#applyCSS .ui-bar-a .ui-link-inherit {
color: orange;
}

How to distinguish lookahead and lookbehind?
Take 2 minutes tour with me:
(?=) - positive lookahead
(?<=) - positive lookbehind
Suppose
A B C #in a line
Now, we ask B, Where are you?
B has two solutions to declare it location:
One, B has A ahead and has C bebind
Two, B is ahead(lookahead) of C and behind (lookhehind) A.
As we can see, the behind and ahead are opposite in the two solutions.
Regex is solution Two.
assuming your using click events, just unbind that one.
example
if (current = 1){
$('li:eq(2)').unbind("click");
}
EDIT:
Are you currently binding a click event to your list somewhere? Based on your comment above, I'm wondering if this is really what you're doing? How are you enabling the click? Is it just an anchor(<a>
tag) ? A little more explicit information will help us answer your question.
UPDATE:
Did some playing around with the :eq() operator. http://jsfiddle.net/ehudokai/VRGfS/5/
As I should have expected it is a 0 based index operator. So if you want to turn of the second element in your selection, where your selection is
$("#navigation a")
you would simply add :eq(1) (the second index) and then .unbind("click") So:
if(current == 1){
$("#navigation a:eq(1)").unbind("click");
}
Ought to do the trick.
Hope this helps!
If you are using Facebook SDK, you don't need to bother yourself to enter anything for redirect URI on the app management page of facebook. Just setup a URL scheme for your iOS app. The URL scheme of your app should be a value "fbxxxxxxxxxxx" where xxxxxxxxxxx is your app id as identified on facebook. To setup URL scheme for your iOS app, go to info tab of your app settings and add URL Type.
If you want to be in a foreach
loop, then foreach($array as $key => $value)
is definitely the recommended approach. Take advantage of simple syntax when a language offers it.
Update 2020: how they made it work while avoiding XSS attacks
GitHub appears to use two security approaches, this is a good article: https://digi.ninja/blog/svg_xss.php see also: https://security.stackexchange.com/questions/148507/how-to-prevent-xss-in-svg-file-upload
show SVG inside <img
tag, which prevents scripts from running, e.g. on READMEs: https://github.com/cirosantilli/test-git-web-interface/tree/8e394cdb012cba4bcf55ebdb89f36872b4c6c12a
use Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; sandbox
. This prevents the script from running even in raw
which contains the raw SVG file: https://raw.githubusercontent.com/cirosantilli/test-git-web-interface/8e394cdb012cba4bcf55ebdb89f36872b4c6c12a/svg-foreignObject.svg
You can see the header with curl -vvv
. The regular github.com
pages also have a content-security-policy
, but it is much larger.
Update 2017
A GitHub dev is currently looking into this: https://github.com/github/markup/issues/556#issuecomment-306103203
Update 2014-12: GitHub now renders SVG on blob show, so I don't see any reason why not to render on README renderings:
Also note that that SVG does have an XSS attempt but it does not run: https://raw.githubusercontent.com/cirosantilli/test/2144a93333be144152e8b0d4144b77b211afce63/svg.svg
The billion laugh SVG does make Firefox 44 Freeze, but Chromium 48 is OK: https://github.com/cirosantilli/web-cheat/blob/master/svg-billion-laughs.svg
Petah mentioned that blobs are fine because the SVG is inside an iframe
.
Possible rationale for GitHub not serving SVG images
general XML vulnerabilities. E.g. opening a billion laughs exploit just made Firefox crash my system. Firefox bug with exploit attached: https://bugzilla.mozilla.org/page.cgi?id=voting/user.html. Same on Chromium: https://code.google.com/p/chromium/issues/detail?id=231562
SVG XSS scripting: while most browsers don't run scripts when the SVG is embedded with img
, it seems that this is not required by the standards, so maybe GitHub is playing it safe.
Browsers do run it if you open the SVG directly (but it appears that GitHub never shows images directly on the github.com
domain) or if it is inline (which are currently completely removed by GitHub), so those cases shouldn't be a security concern. Relevant links:
The following questions asks about the risks of SVG in general: https://security.stackexchange.com/questions/11384/exploits-or-other-security-risks-with-svg-upload
You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):
dataGridView1.Columns[1].Width = 108; // or whatever width works well for abbrev
dataGridView1.Columns[2].Width =
dataGridView1.Width
- dataGridView1.Columns[0].Width
- dataGridView1.Columns[1].Width
- 72; // this is an extra "margin" number of pixels
If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize
event handler of the DataGridView.
In case someone like me didn't really understand what all above are talking about, I give an easy example which is working for me. If you have a web api which url is "http://somesite.com/verifyAddress", it is a post method and it need you to pass it an address object. You want to call this api in your code. Here what you can do.
public Address verifyAddress(Address address)
{
this.client = new HttpClient();
client.BaseAddress = new Uri("http://somesite.com/");
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var urlParm = URL + "verifyAddress";
response = client.PostAsJsonAsync(urlParm,address).Result;
var dataObjects = response.IsSuccessStatusCode ? response.Content.ReadAsAsync<Address>().Result : null;
return dataObjects;
}
Sometimes it's case sensitive. Have you tried going to http://localhost/phpMyAdmin
?
If you want to write a script to automate creation of jobs using the Jenkins API, you can use one of the API clients to do that. A ruby client for Jenkins is available at https://github.com/arangamani/jenkins_api_client
gem install jenkins_api_client
require "rubygems"
require "jenkins_api_client"
# Initialize the client by passing in the server information
# and credentials to communicate with the server
client = JenkinsApi::Client.new(
:server_ip => "127.0.0.1",
:username => "awesomeuser",
:password => "awesomepassword"
)
# The following block will create 10 jobs in Jenkins
# test_job_0, test_job_1, test_job_2, ...
10.times do |num|
client.job.create_freestyle(:name => "test_job_#{num}")
end
# The jobs in Jenkins can be listed using
client.job.list_all
The API client can be used to perform a lot of operations.

As said before, VBA does not support Multithreading.
But you don't need to use C# or vbScript to start other VBA worker threads.
I use VBA to create VBA worker threads.
First copy the makro workbook for every thread you want to start.
Then you can start new Excel Instances (running in another Thread) simply by creating an instance of Excel.Application (to avoid errors i have to set the new application to visible).
To actually run some task in another thread i can then start a makro in the other application with parameters form the master workbook.
To return to the master workbook thread without waiting i simply use Application.OnTime in the worker thread (where i need it).
As semaphore i simply use a collection that is shared with all threads. For callbacks pass the master workbook to the worker thread. There the runMakroInOtherInstance Function can be reused to start a callback.
'Create new thread and return reference to workbook of worker thread
Public Function openNewInstance(ByVal fileName As String, Optional ByVal openVisible As Boolean = True) As Workbook

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).
We're not necessarily talking theoretical limits here, we're talking about real world limits of the 2GB max file size AND database schema.
The schema is on even footing with the row count in determining how many rows you can have.
We have used Access MDBs to store exports of MS-SQL data for statistical analysis by some of our corporate users. In those cases we've exported our core table structure, typically four tables with 20 to 150 columns varying from a hundred bytes per row to upwards of 8000 bytes per row. In these cases, we would bump up against a few hundred thousand rows of data were permissible PER MDB that we would ship them.
So, I just don't think that this question has an answer in absence of your schema.
This will resolve your error. Run these commands in your terminal. These commands will add the older versions. You can update them later or you can change version here too before running these commands one by one.

The proper way to fully uninstall conda (Anaconda / Miniconda):
Remove all conda-related files and directories using the Anaconda-Clean package
conda activate your_conda_env_name
conda install anaconda-clean
anaconda-clean # add `--yes` to avoid being prompted to delete each one
Remove your entire conda directory
rm -rf ~/miniconda3
Remove the line which adds the conda path to the PATH
environment variable
vi ~/.bashrc
# -> Search for conda and delete the lines containing it
# -> If you're not sure if the line belongs to conda, comment it instead of deleting it just to be safe
source ~/.bashrc
Remove the backup folder created by the the Anaconda-Clean package NOTE: Think twice before doing this, because after that you won't be able to restore anything from your old conda installation!
rm -rf ~/.anaconda_backup

We will have to use git cherry-pick <commit-number>
Scenario: I am on a branch called release and I want to add only few changes from master branch to release branch.
Step 1: checkout the branch where you want to add the changes
git checkout release
Step 2: get the commit number of the changes u want to add
for example
git cherry-pick 634af7b56ec
Step 3: git push
Note: Every time your merge there is a separate commit number create. Do not take the commit number for merge that won't work. Instead, the commit number for any regular commit u want to add.
Create an Arraylist of unique values
You could use Set.toArray()
method.
A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element. As implied by its name, this interface models the mathematical set abstraction.
Another way to get the apk
s you can't find, on a rooted device is with rom tool box.
Make a backup using app manager then go to storage/emulated/appmanager

Using @Adrian Frühwirth answer:

Best way to find the average of some numbers is trying Classes ......
public static void main(String[] args) {
average(1,2,5,4);
}
public static void average(int...numbers){
int total = 0;
for(int x: numbers){
total+=x;
}
System.out.println("Average is: "+(double)total/numbers.length);
}

Yes, you can always use null

It would be 1.
also null

There are already so many good answers on this thread! I am going to post this to help anybody trying to do this automatically! To automatically remove unused imports for the whole project this article was really helpful to me.
In the article the author explains it like this:
Make a stand alone tslint file that has the following in it:
{
"extends": ["tslint-etc"],
"rules": {
"no-unused-declaration": true
}
}
Then run the following command to fix the imports:
tslint --config tslint-imports.json --fix --project .
Consider fixing any other errors it throws. (I did)
Then check the project works by building it:
ng build
or
ng build name_of_project --configuration=production
End: If it builds correctly, you have successfully removed imports automatically!
NOTE: This only removes unnecessary imports. It does not provide the other features that VS Code does when using one of the commands previously mentioned.
The domain name portion of a URL is not case sensitive since DNS ignores case:
http://en.example.org/
and HTTP://EN.EXAMPLE.ORG/
both open the same page.
The path is used to specify and perhaps find the resource requested. It is case-sensitive, though it may be treated as case-insensitive by some servers, especially those based on Microsoft Windows.
If the server is case sensitive and http://en.example.org/wiki/URL
is correct, then http://en.example.org/WIKI/URL
or http://en.example.org/wiki/url
will display an HTTP 404 error page, unless these URLs point to valid resources themselves.
The following will just print out the content of the file:
cat $Path/FileName.txt
while read line;
do
echo $line
done
If you are using a local .mdf file, probably a sync software such Dropbox attempted to sync two log files (.ldf) in two different computers you can delete the log files from the bin Directory and make sure the .mdf properties->Copy to Output Directory ->Copy if newer that will copy the selected DB file and it's log to the bin Directory. !Alert- if your DB file has only changed in the bin Directory all the changes ill be discarded!
invoke run()
is executing on the calling thread, like any other method call. whereas Thread.start()
creates a new thread.
invoking run()
is a programmatic bug.
The way I typically handle this is with a second piece of software. For Windows I use Notepad++, for OS X I use Sublime Text 2.
The following snippet (from the dotnet samples) demonstrates how:
public static Dictionary<int, string> EnumNamedValues<T>() where T : System.Enum
{
var result = new Dictionary<int, string>();
var values = Enum.GetValues(typeof(T));
foreach (int item in values)
result.Add(item, Enum.GetName(typeof(T), item));
return result;
}

Which generates a function that would look like this, if it were valid C#:
T GetEnumFromString<T>(string valueString, T defaultValue) where T : Enum
Then with the following C# code:
using MyThing;
// stuff...
private enum MyEnum { Yes, No, Okay }
static void Main(string[] args)
{
Thing.GetEnumFromString("No", MyEnum.Yes); // returns MyEnum.No
Thing.GetEnumFromString("Invalid", MyEnum.Okay); // returns MyEnum.Okay
Thing.GetEnumFromString("AnotherInvalid", 0); // compiler error, not an Enum
}
Unfortunately, this means having this part of your code written in MSIL instead of C#, with the only added benefit being that you're able to constrain this method by System.Enum
. It's also kind of a bummer, because it gets compiled into a separate assembly. However, it doesn't mean you have to deploy it that way.
By removing the line .assembly MyThing{}
and invoking ilasm as follows:
ilasm.exe /DLL /OUTPUT=MyThing.netmodule
you get a netmodule instead of an assembly.
Unfortunately, VS2010 (and earlier, obviously) does not support adding netmodule references, which means you'd have to leave it in 2 separate assemblies when you're debugging. The only way you can add them as part of your assembly would be to run csc.exe yourself using the /addmodule:{files}
command line argument. It wouldn't be too painful in an MSBuild script. Of course, if you're brave or stupid, you can run csc yourself manually each time. And it certainly gets more complicated as multiple assemblies need access to it.
So, it CAN be done in .Net. Is it worth the extra effort? Um, well, I guess I'll let you decide on that one.
Extra Credit: It turns out that a generic restriction on enum
is possible in at least one other .NET language besides MSIL: F#.
type MyThing =
static member GetEnumFromString<'T when 'T :> Enum> str defaultValue: 'T =
/// protect for null (only required in interop with C#)
let str = if isNull str then String.Empty else str
Enum.GetValues(typedefof<'T>)
|> Seq.cast<_>
|> Seq.tryFind(fun v -> String.Compare(v.ToString(), str.Trim(), true) = 0)
|> function Some x -> x | None -> defaultValue
This one is easier to maintain since it's a well-known language with full Visual Studio IDE support, but you still need a separate project in your solution for it. However, it naturally produces considerably different IL (the code is very different) and it relies on the FSharp.Core
library, which, just like any other external library, needs to become part of your distribution.
Here's how you can use it (basically the same as the MSIL solution), and to show that it correctly fails on otherwise synonymous structs:
// works, result is inferred to have type StringComparison
var result = MyThing.GetEnumFromString("OrdinalIgnoreCase", StringComparison.Ordinal);
// type restriction is recognized by C#, this fails at compile time
var result = MyThing.GetEnumFromString("OrdinalIgnoreCase", 42);
As you've indicated, you can't output NULL in an excel formula. I think this has to do with the fact that the formula itself causes the cell to not be able to be NULL. "" is the next best thing, but sometimes it's useful to use 0.
--EDIT--
Based on your comment, you might want to check out this link. http://peltiertech.com/WordPress/mind-the-gap-charting-empty-cells/
It goes in depth on the graphing issues and what the various values represent, and how to manipulate their output on a chart.
I'm not familiar with VSTO I'm afraid. So I won't be much help there. But if you are really placing formulas in the cell, then there really is no way. ISBLANK() only tests to see if a cell is blank or not, it doesn't have a way to make it blank. It's possible to write code in VBA (and VSTO I imagine) that would run on a worksheet_change event and update the various values instead of using formulas. But that would be cumbersome and performance would take a hit.
when you add more space between double quotes or single quotes PHP takes only one white space ,so if you want to add more white space between words or strings use tab '\t' sequence
echo "\t";
This catches every exit event I can find that can be handled. Seems quite reliable and clean so far.
[`exit`, `SIGINT`, `SIGUSR1`, `SIGUSR2`, `uncaughtException`, `SIGTERM`].forEach((eventType) => {
process.on(eventType, cleanUpServer.bind(null, eventType));
})
After a few days of struggle, this works for me, and I hope this also works for you.
add this to your CONFIG.XML, top of your code.
<access origin="*" />
<allow-navigation href="*" />
and this, under the platform android.

</edit-config>
<resource-file src="resources/android/xml/network_security_config.xml"

add the follow code to this file "resources/android/xml/network_security_config.xml".

Two ways you can do that:
Removing JDK directly from Users-> Library -> Java -> VirtualMachines -> then delete the jdk folder directly to uninstall the java.
By following the command: (uninstall java 1.8 version )
make sure you are in home directory by using below command, before you write the command:
cd ~/
sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.jdk
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -rf /Library/Application\ Support/Oracle/Java
Swift 3 version
import UIKit
protocol PhoneCalling {
func call(phoneNumber: String)
}
extension PhoneCalling {
func call(phoneNumber: String) {
let cleanNumber = phoneNumber.replacingOccurrences(of: " ", with: "").replacingOccurrences(of: "-", with: "")
guard let number = URL(string: "telprompt://" + cleanNumber) else { return }
UIApplication.shared.open(number, options: [:], completionHandler: nil)
}
}
Perhaps this example could explain.
CREATE TABLE `test`(`fla` FLOAT,`flb` FLOAT,`dba` DOUBLE(10,2),`dbb` DOUBLE(10,2));
We have a table like this:
+-------+-------------+
| Field | Type |
+-------+-------------+
| fla | float |
| flb | float |
| dba | double(10,2)|
| dbb | double(10,2)|
+-------+-------------+
For first difference, we try to insert a record with '1.2' to each field:
INSERT INTO `test` values (1.2,1.2,1.2,1.2);
The table showing like this:
SELECT * FROM `test`;
+------+------+------+------+
| fla | flb | dba | dbb |
+------+------+------+------+
| 1.2 | 1.2 | 1.20 | 1.20 |
+------+------+------+------+
See the difference?
We try to next example:
SELECT fla+flb, dba+dbb FROM `test`;
Hola! We can find the difference like this:
+--------------------+---------+
| fla+flb | dba+dbb |
+--------------------+---------+
| 2.4000000953674316 | 2.40 |
+--------------------+---------+
The question is kind of old, but I get a good result creating a function to convert an object in a Json string from a string variable to an integer
function getInt(arr, prop) {
var int;
for (var i=0 ; i<arr.length ; i++) {
int = parseInt(arr[i][prop])
arr[i][prop] = int;
}
return arr;
}
the function just go thru the array and return all elements of the object of your selection as an integer
The response from Marco is the BEST solution. I needed to control my error handling, and I mean really CONTROL it. Of course, I have extended the solution a little and created a full error management system that manages everything. I have also read about this solution in other blogs and it seems very acceptable by most of the advanced developers.
Here is the final code that I am using:
protected void Application_EndRequest()
{
if (Context.Response.StatusCode == 404)
{
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "ErrorManager";
routeData.Values["action"] = "Fire404Error";
routeData.Values["exception"] = exception;
Response.StatusCode = 500;
if (httpException != null)
{
Response.StatusCode = httpException.GetHttpCode();
switch (Response.StatusCode)
{
case 404:
routeData.Values["action"] = "Fire404Error";
break;
}
}
// Avoid IIS7 getting in the middle
Response.TrySkipIisCustomErrors = true;
IController errormanagerController = new ErrorManagerController();
HttpContextWrapper wrapper = new HttpContextWrapper(Context);
var rc = new RequestContext(wrapper, routeData);
errormanagerController.Execute(rc);
}
}
and inside my ErrorManagerController :
public void Fire404Error(HttpException exception)
{
//you can place any other error handling code here
throw new PageNotFoundException("page or resource");
}
Now, in my Action, I am throwing a Custom Exception that I have created. And my Controller is inheriting from a custom Controller Based class that I have created. The Custom Base Controller was created to override error handling. Here is my custom Base Controller class:
public class MyBasePageController : Controller
{
protected override void OnException(ExceptionContext filterContext)
{
filterContext.GetType();
filterContext.ExceptionHandled = true;
this.View("ErrorManager", filterContext).ExecuteResult(this.ControllerContext);
base.OnException(filterContext);
}
}
The "ErrorManager" in the above code is just a view that is using a Model based on ExceptionContext
My solution works perfectly and I am able to handle ANY error on my website and display different messages based on ANY exception type.
I started to get the issue today only on chrome and not safari for the same project/url for my goormide container (node.js)
After trying several suggestions above which didn't appear to work and backtracking on some code changes I made from yesterday to today which also made no difference I ended up in the chrome settings clicking:
1.Settings;
2.scroll down to bottom, select: "Advanced";
3.scroll down to bottom, select: "Restore settings to their original defaults";
That appears to have fixed the problem as I no longer get the warning/error in the console and the page displays as it should. Reading the posts above it appears the issue can occur from any number of sources so the settings reset is a potential generic fix. Cheers
Instead of using ->bindParam()
you can pass the data only at the time of ->execute()
:
$data = [ ':item_name' => $_POST['item_name'], ':item_type' => $_POST['item_type'], ':item_price' => $_POST['item_price'], ':item_description' => $_POST['item_description'], ':image_location' => 'images/'.$_FILES['file']['name'], ':status' => 0, ':id' => 0, ]; $stmt->execute($data);
In this way you would know exactly what values are going to be sent.
This logic will first convert the items in list to string(str)
. Sometimes the list contains a tuple like
alist = [(i12,tiger),
(113,lion)]
This logic will write to file each tuple in a new line. We can later use eval
while loading each tuple when reading the file:
outfile = open('outfile.txt', 'w') # open a file in write mode
for item in list_to_persistence: # iterate over the list items
outfile.write(str(item) + '\n') # write to the file
outfile.close() # close the file
Using .editorconfig
to fix the tabs automagically:
root = true
[*]
charset = utf-8
end_of_line = lf
insert_final_newline = true
indent_style = space
indent_size = 4
[Makefile]
indent_style = tab
I was going to write up my own explanation but this Wikipedia article pretty much sums it up.
Here is the basic concept:
Copy-on-write (sometimes referred to as "COW") is an optimization strategy used in computer programming. The fundamental idea is that if multiple callers ask for resources which are initially indistinguishable, you can give them pointers to the same resource. This function can be maintained until a caller tries to modify its "copy" of the resource, at which point a true private copy is created to prevent the changes becoming visible to everyone else. All of this happens transparently to the callers. The primary advantage is that if a caller never makes any modifications, no private copy need ever be created.
Also here is an application of a common use of COW:
The COW concept is also used in maintenance of instant snapshot on database servers like Microsoft SQL Server 2005. Instant snapshots preserve a static view of a database by storing a pre-modification copy of data when underlaying data are updated. Instant snapshots are used for testing uses or moment-dependent reports and should not be used to replace backups.
Yes, you can use jQuery's attribute selector for that.
var linksToGoogle = $('a[href="http://google.com"]');
Alternatively, if your interest is rather links starting with a certain URL, use the attribute-starts-with selector:
var allLinksToGoogle = $('a[href^="http://google.com"]');
Best way is to use Joda-Time, the highly successful open-source library you would add to your project.
String date1 = "2015-11-11";
String date2 = "2013-11-11";
DateTimeFormatter formatter = new DateTimeFormat.forPattern("yyyy-MM-dd");
DateTime d1 = formatter.parseDateTime(date1);
DateTime d2 = formatter.parseDateTime(date2);
long diffInMillis = d2.getMillis() - d1.getMillis();
Duration duration = new Duration(d1, d2);
int days = duration.getStandardDays();
int hours = duration.getStandardHours();
int minutes = duration.getStandardMinutes();
If you're using Android Studio, very easy to add joda-time. In your build.gradle (app):
dependencies {
compile 'joda-time:joda-time:2.4'
compile 'joda-time:joda-time:2.4'
compile 'joda-time:joda-time:2.2'
}
Column(
children: <Widget>[
FirstWidget(),
Spacer(),
SecondWidget(),
]
)
Spacer creates a flexible space to insert into a [Flexible] widget. (Like a column)
I had a similar issue. I had mentioned a wrong output folder path in angular.json
"outputPath": "dist/",
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'dist/index.html'));
});
Just implemented my OWIN Service with Bearer (called access_token in the following) and Refresh Tokens. My insight into this is that you can use different flows. So it depends on the flow you want to use how you set your access_token and refresh_token expiration times.
I will describe two flows A and B in the follwing (I suggest what you want to have is flow B):
A) expiration time of access_token and refresh_token are the same as it is per default 1200 seconds or 20 minutes. This flow needs your client first to send client_id and client_secret with login data to get an access_token, refresh_token and expiration_time. With the refresh_token it is now possible to get a new access_token for 20 minutes (or whatever you set the AccessTokenExpireTimeSpan in the OAuthAuthorizationServerOptions to). For the reason that the expiration time of access_token and refresh_token are the same, your client is responsible to get a new access_token before the expiration time! E.g. your client could send a refresh POST call to your token endpoint with the body (remark: you should use https in production)
grant_type=refresh_token&client_id=xxxxxx&refresh_token=xxxxxxxx-xxxx-xxxx-xxxx-xxxxx
to get a new token after e.g. 19 minutes to prevent the tokens from expiration.
B) in this flow you want to have a short term expiration for your access_token and a long term expiration for your refresh_token. Lets assume for test purpose you set the access_token to expire in 10 seconds (AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(10)
) and the refresh_token to 5 Minutes. Now it comes to the interesting part setting the expiration time of refresh_token: You do this in your createAsync function in SimpleRefreshTokenProvider class like this:
var guid = Guid.NewGuid().ToString();
//copy properties and set the desired lifetime of refresh token
var refreshTokenProperties = new AuthenticationProperties(context.Ticket.Properties.Dictionary)
{
IssuedUtc = context.Ticket.Properties.IssuedUtc,
ExpiresUtc = DateTime.UtcNow.AddMinutes(5) //SET DATETIME to 5 Minutes
//ExpiresUtc = DateTime.UtcNow.AddMonths(3)
};
/*CREATE A NEW TICKET WITH EXPIRATION TIME OF 5 MINUTES
*INCLUDING THE VALUES OF THE CONTEXT TICKET: SO ALL WE
*DO HERE IS TO ADD THE PROPERTIES IssuedUtc and
*ExpiredUtc to the TICKET*/
var refreshTokenTicket = new AuthenticationTicket(context.Ticket.Identity, refreshTokenProperties);
//saving the new refreshTokenTicket to a local var of Type ConcurrentDictionary<string,AuthenticationTicket>
// consider storing only the hash of the handle
RefreshTokens.TryAdd(guid, refreshTokenTicket);
context.SetToken(guid);
Now your client is able to send a POST call with a refresh_token to your token endpoint when the access_token
is expired. The body part of the call may look like this: grant_type=refresh_token&client_id=xxxxxx&refresh_token=xxxxxxxx-xxxx-xxxx-xxxx-xx
One important thing is that you may want to use this code not only in your CreateAsync function but also in your Create function. So you should consider to use your own function (e.g. called CreateTokenInternal) for the above code. Here you can find implementations of different flows including refresh_token flow(but without setting the expiration time of the refresh_token)
Here is one sample implementation of IAuthenticationTokenProvider on github (with setting the expiration time of the refresh_token)
I am sorry that I can't help out with further materials than the OAuth Specs and the Microsoft API Documentation. I would post the links here but my reputation doesn't let me post more than 2 links....
I hope this may help some others to spare time when trying to implement OAuth2.0 with refresh_token expiration time different to access_token expiration time. I couldn't find an example implementation on the web (except the one of thinktecture linked above) and it took me some hours of investigation until it worked for me.
New info: In my case I have two different possibilities to receive tokens. One is to receive a valid access_token. There I have to send a POST call with a String body in format application/x-www-form-urlencoded with the following data
client_id=YOURCLIENTID&grant_type=password&username=YOURUSERNAME&password=YOURPASSWORD
Second is if access_token is not valid anymore we can try the refresh_token by sending a POST call with a String body in format application/x-www-form-urlencoded
with the following data grant_type=refresh_token&client_id=YOURCLIENTID&refresh_token=YOURREFRESHTOKENGUID

Further to RolandTumble's answer to Cody Gray's answer, both fine answers, here is another very simple and flexible way, when you know all of the array contents at coding time - e.g. you just want to build an array that contains 1, 10, 20 and 50. This also uses variant declaration, but doesn't use ReDim. Like in Roland's answer, the enumerated count of the number of array elements need not be specifically known, but is obtainable by using uBound.
sub Demo_array()
Dim MyArray as Variant, MyArray2 as Variant, i as Long
MyArray = Array(1, 10, 20, 50) 'The key - the powerful Array() statement
MyArray2 = Array("Apple", "Pear", "Orange") 'strings work too
For i = 0 to UBound(MyArray)
Debug.Print i, MyArray(i)
Next i
For i = 0 to UBound(MyArray2)
Debug.Print i, MyArray2(i)
Next i
End Sub
I love this more than any of the other ways to create arrays. What's great is that you can add or subtract members of the array right there in the Array statement, and nothing else need be done to code. To add Egg to your 3 element food array, you just type
, "Egg"
in the appropriate place, and you're done. Your food array now has the 4 elements, and nothing had to be modified in the Dim, and ReDim is omitted entirely.
If a 0-based array is not desired - i.e., using MyArray(0) - one solution is just to jam a 0 or "" for that first element.
Note, this might be regarded badly by some coding purists; one fair objection would be that "hard data" should be in Const statements, not code statements in routines. Another beef might be that, if you stick 36 elements into an array, you should set a const to 36, rather than code in ignorance of that. The latter objection is debatable, because it imposes a requirement to maintain the Const with 36 rather than relying on uBound. If you add a 37th element but leave the Const at 36, trouble is possible.
t = (1, 2, 3)
# the comma (,) concatenates the strings and adds a space
print "this is a tuple", (t)
# format is the most flexible way to do string formatting
print "this is a tuple {0}".format(t)
# classic string formatting
# I use it only when working with older Python versions
print "this is a tuple %s" % repr(t)
print "this is a tuple %s" % str(t)
Install PIL(Python Image Library) :
then:
from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();
You cannot change a table while the INSERT trigger is firing. The INSERT might do some locking which could result in a deadlock. Also, updating the table from a trigger would then cause the same trigger to fire again in an infinite recursive loop. Both of these reasons are why MySQL prevents you from doing this.
However, depending on what you're trying to achieve, you can access the new values by using NEW.fieldname or even the old values--if doing an UPDATE--with OLD.
If you had a row named full_brand_name
and you wanted to use the first two letters as a short name in the field small_name
you could use:
CREATE TRIGGER `capital` BEFORE INSERT ON `brandnames`
FOR EACH ROW BEGIN
SET NEW.short_name = CONCAT(UCASE(LEFT(NEW.full_name,1)) , LCASE(SUBSTRING(NEW.full_name,2)))
END
You could use the between function to get all records between 2010-08-03 00:00:00:000 AND 2010-08-03 23:59:59:000
If you are grouping by some other value, then instead of what you have,
write it as
Sum(CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END) as SumSomeProduct
If, otoh, you want to group By
the internal expression, (col3*col4)
then
write the group By
to match the expression w/o the SUM
...
Select Sum(Case When col1 > col2 Then col3*col4 Else 0 End) as SumSomeProduct
From ...
Group By Case When col1 > col2 Then col3*col4 Else 0 End
Finally, if you want to group By the actual aggregate
Select SumSomeProduct, Count(*), <other aggregate functions>
From (Select <other columns you are grouping By>,
Sum(Case When col1 > col2
Then col3*col4 Else 0 End) as SumSomeProduct
From Table
Group By <Other Columns> ) As Z
Group by SumSomeProduct
Also, if you want cellspacing="0"
, don't forget to add border-collapse: collapse
in your table
's stylesheet.
do you try
[{"name":"myEnterprise", "departments":["HR"]}]
the square brace is the key point.
Okay, this maybe an old post... but was first result in google and decided to make your own mix on this as..
FIRSTLY I WILL USE FOCUS
The reason for this is that it works nicely for the example i'm showing, if someone wants a mouse down type event then use active
THE HTML CODE:
<button class="mdT mdI1" ></button>
<button class="mdT mdI2" ></button>
<button class="mdT mdI3" ></button>
<button class="mdT mdI4" ></button>
THE CSS CODE:
/* Change Button Size/Border/BG Color And Align To Middle */
.mdT {
width:96px;
height:96px;
border:0px;
outline:0;
vertical-align:middle;
background-color:#AAAAAA;
}
.mdT:focus {
width:256px;
height:256px;
}
/* Change Images Depending On Focus */
.mdI1 { background-image:url('http://placehold.it/96x96/AAAAAA&text=img1'); }
.mdI1:focus { background-image:url('http://placehold.it/256x256/555555&text=Image+1'); }
.mdI2 { background-image:url('http://placehold.it/96x96/AAAAAA&text=img2'); }
.mdI2:focus { background-image:url('http://placehold.it/256x256/555555&text=Image+2'); }
.mdI3 { background-image:url('http://placehold.it/96x96/AAAAAA&text=img3'); }
.mdI3:focus { background-image:url('http://placehold.it/256x256/555555&text=Image+3'); }
.mdI4 { background-image:url('http://placehold.it/96x96/AAAAAA&text=img4'); }
.mdI4:focus { background-image:url('http://placehold.it/256x256/555555&text=Image+4'); }

So why am i posting this in an old thread, well because the examples here vary and i thought to provide one back to the community which is a working example.
As already answered by the thread creator, they only want the effect to last during the click event. Now while this is not exact for that need, its close. active will animate while the mouse is down and any changes that you need to have last longer need to be done with javascript.
If you don't want to commit, or want to commit later (commit message will still be prepared for you, which you can also edit):
git revert -n <commit>
I put the year and the number series of my app example 2014-01
You can use the variables name itself to check if a value is an integer. for example:
#include <iostream>
using namespace std;
int main (){
int firstvariable;
int secondvariable;
float float1;
float float2;
cout << "Please enter two integers and then press Enter:" << endl;
cin >> firstvariable;
cin >> secondvariable;
if(firstvariable && secondvariable){
cout << "Time for some simple mathematical operations:\n" << endl;
cout << "The sum:\n " << firstvariable << "+" << secondvariable
<<"="<< firstvariable + secondvariable << "\n " << endl;
}else{
cout << "\n[ERROR\tINVALID INPUT]\n";
return 1;
}
return 0;
}
