Do you mean the conversion 011001100110111101101111
? foo
, for example? You just take the binary stream, split it into separate bytes (01100110
, 01101111
, 01101111
) and look up the ASCII character that corresponds to given number. For example, 01100110
is 102 in decimal and the ASCII character with code 102 is f
:
$ perl -E 'say 0b01100110'
102
$ perl -E 'say chr(102)'
f
(See what the chr
function does.) You can generalize this algorithm and have a different number of bits per character and different encodings, the point remains the same.

One can use AMD GPU via the PlaidML Keras backend.
Fastest: PlaidML is often 10x faster (or more) than popular platforms (like TensorFlow CPU) because it supports all GPUs, independent of make and model. PlaidML accelerates deep learning on AMD, Intel, NVIDIA, ARM, and embedded GPUs.
Easiest: PlaidML is simple to install and supports multiple frontends (Keras and ONNX currently)
Free: PlaidML is completely open source and doesn't rely on any vendor libraries with proprietary and restrictive licenses.
For most platforms, getting started with accelerated deep learning is as easy as running a few commands (assuming you have Python (v2 or v3) installed):
virtualenv plaidml
source plaidml/bin/activate
pip install plaidml-keras plaidbench
Choose which accelerator you'd like to use (many computers, especially laptops, have multiple):
plaidml-setup
Next, try benchmarking MobileNet inference performance:
plaidbench keras mobilenet
Or, try training MobileNet:
plaidbench --batch-size 16 keras --train mobilenet
To use it with keras set
os.environ["KERAS_BACKEND"] = "plaidml.keras.backend"

exec is for statement and does not return anything. eval is for expression and returns value of expression.
expression means "something" while statement means "do something".
I believe it stems from the Python creed that "explicit is better than implicit".
For those of you who would prefer an Object
as opposed to a serialized string (like the one returned by $(form).serialize()
, and a slight improvement on $(form).serializeArray()
), feel free to use the code below:
var Form = {
_form: null,
_validate: function(){
if(!this._form || this._form.tagName.toLowerCase() !== "form") return false;
if(!this._form.elements.length) return false;
}, _loopFields: function(callback){
var elements = this._form.elements;
for(var i = 0; i < elements.length; i++){
var element = form.elements[i];
if(name !== ""){
callback(this._valueOfField(element));
}
}
}, _valueOfField: function(element){
var type = element.type;
var name = element.name.trim();
var nodeName = element.nodeName.toLowerCase();
switch(nodeName){
case "input":
if(type === "radio" || type === "checkbox"){
if(element.checked){
return element.value;
}
}
return element.value;
break;
case "select":
if(type === "select-multiple"){
for(var i = 0; i < element.options.length; i++){
if(options[i].selected){
return element.value;
}
}
}
return element.value;
break;
case "button":
switch(type){
case "reset":
case "submit":
case "button":
return element.value;
break;
}
break;
}
}, serialize: function(form){
var data = {};
this._form = form;
if(this._validate()){
this._loopFields(function(value){
if(value !== null) data[name] = value;
});
}
return data;
}
};
To execute it, just use Form.serialize(form)
and the function will return an Object
similar to this:
<!-- { username: "username", password: "password" } !-->
<input type="text" value="username">
<input type="password" value="password">
As a bonus, it means you don't have to install the entire bundle of jQuery just for one serialize function.
h:button
- clicking on a h:button
issues a bookmarkable GET
request.
h:commandbutton
- Instead of a get request, h:commandbutton
issues a POST request which sends the form data back to the server.
Because HTTP is stateless, in order to associate a request to any other request, you need a way to store user data between HTTP requests.
Cookies or URL parameters ( for ex. like http://example.com/myPage?asd=lol&boo=no ) are both suitable ways to transport data between 2 or more request. However they are not good in case you don't want that data to be readable/editable on client side.
The solution is to store that data server side, give it an "id", and let the client only know (and pass back at every http request) that id. There you go, sessions implemented. Or you can use the client as a convenient remote storage, but you would encrypt the data and keep the secret server-side.
Of course there are other aspects to consider, like you don't want people to hijack other's sessions, you want sessions to not last forever but to expire, and so on.
In your specific example, the user id (could be username or another unique ID in your user database) is stored in the session data, server-side, after successful identification. Then for every HTTP request you get from the client, the session id (given by the client) will point you to the correct session data (stored by the server) that contains the authenticated user id - that way your code will know what user it is talking to.
window.top.location.href = "http://www.example.com";

window.parent.location.href = "http://www.example.com";
Will redirect the parent iframe.
The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.
Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.
If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/
is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/
or http://s3-external-1.amazonaws.com/bucket/
.¹
The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].
S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com
. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.
If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.
However... the two endpoints do not offer the same functionality.
Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.
Choose the correct type of endpoint (REST or web site) for your application:
http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff
¹ s3-external-1.amazonaws.com
has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com
. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2
had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1
so s3-external-2
appears to have no purpose except backwards-compatibility.
What you should do is to serialize your form data and send it to the controller action. ASP.NET MVC will bind the form data to the EditPostViewModel
object( your action method parameter), using MVC model binding feature.
You can validate your form at client side and if everything is fine, send the data to server. The valid()
method will come in handy.
$(function () {
$("#yourSubmitButtonID").click(function (e) {
e.preventDefault();
var _this = $(this);
var _form = _this.closest("form");
var isvalid = _form .valid(); // Tells whether the form is valid
if (isvalid)
{
$.post(_form.attr("action"), _form.serialize(), function (data) {
//check the result and do whatever you want
})
}
});
});

Right click on Cell B1
and choose Format Cells. In Custom, put the following in the text box labeled Type:
[h]:mm:ss.000
To set this in code, you can do something like:
Range("A1").NumberFormat = "[h]:mm:ss.000"
That should give you what you're looking for.
NOTE: Specially formatted fields often require that the column width be wide enough for the entire contents of the formatted text. Otherwise, the text will display as ######
.
You don't need quotes around the variable, so simply change this:
Get-ADComputer -Filter {name -like '$nameregex' -and Enabled -eq "true"}
into this:
Get-ADComputer -Filter {name -like $nameregex -and Enabled -eq "true"}
Note, however, that the scriptblock notation for filter statements is misleading, because the statement is actually a string, so it's better to write it as such:
Get-ADComputer -Filter "name -like '$nameregex' -and Enabled -eq 'true'"
And FTR: you're using wildcard matching here (operator -like
), not regular expressions (operator -match
).
Difficulties with defining, what's legal and not were already adressed and whitelists were suggested. But Windows supports more-than-8-bit characters. Wikipedia states, that (for example) the
modifier letter colon [(See 7. below) is] sometimes used in Windows filenames as it is identical to the colon in the Segoe UI font used for filenames. The [inherited ASCII] colon itself is not permitted.
Therefore, I want to present a much more liberal approach using Unicode characters to replace the "illegal" ones. I found the result in my comparable use-case by far more readable. Plus you can even restore the original content from the replacements. Possible choices and research are provided in the following list:
U+002A * ASTERISK
), you can use one of the many listed, for example U+2217 * (ASTERISK OPERATOR)
or the Full Width Asterisk U+FF0A *
· U+22C5 dot operator
“ U+201C english leftdoublequotemark
(Alternatives see here)/ SOLIDUS U+002F
), you can use / DIVISION SLASH U+2215
(others here)\
(\ U+005C Reverse solidus
), you can use ? U+29F5 Reverse solidus operator
(more)U+005B Left square bracket
) and ] (U+005D Right square bracket
), you can use for example U+FF3B[ FULLWIDTH LEFT SQUARE BRACKET
and U+FF3D ]FULLWIDTH RIGHT SQUARE BRACKET
(from here, more possibilities here)U+2236 : RATIO (for mathematical usage)
or U+A789 ? MODIFIER LETTER COLON
, (see colon (letter), sometimes used in Windows filenames as it is identical to the colon in the Segoe UI font used for filenames. The colon itself is not permitted) (See here)U+037E ; GREEK QUESTION MARK
(see here)U+0964 ? DEVANAGARI DANDA
, U+2223 | DIVIDES
or U+01C0 | LATIN LETTER DENTAL CLICK
(Wikipedia). Also the box drawing characters contain various other options., U+002C COMMA
), you can use for example ‚ U+201A SINGLE LOW-9 QUOTATION MARK
(see here)U+003F ? QUESTION MARK
), these are good candidates: U+FF1F ? FULLWIDTH QUESTION MARK
or U+FE56 ? SMALL QUESTION MARK
(from here, two more from Dingbats Block, search for "question")For additional ideas, you can also look for example into this block. In Windows, these special characters should theoretically be able to be typed by using an alt-code, but I only found a solution to insert it in Microsoft Office in this Microsoft article using ALT + X. It can of course still be copied instead of typed.

It installs the latest version using a Chocolatey repository.
Originally I was using command cinst powershell 3.0.20121027
, but it looks like it later stopped working. Since this question is related to PowerShell 3.0 this was the right way. At this moment (June 26, 2014) cinst powershell
refers to version 3.0 of PowerShell, and that may change in future.
See the Chocolatey PowerShell package page for details on what version will be installed.

I used the solution posted by CSL but I would recommend you dont store the file data in Session during the whole session. By using TempData the file data is automatically removed after the next request (which is the GET request for the file). You could also manage removal of the file data in Session in download action.
Session could consume much memory/space depending on SessionState storage and how many files are exported during the session and if you have many users.
I've updated the serer side code from CSL to use TempData instead.
public ActionResult PostReportPartial(ReportVM model){
// Validate the Model is correct and contains valid data
// Generate your report output based on the model parameters
// This can be an Excel, PDF, Word file - whatever you need.
// As an example lets assume we've generated an EPPlus ExcelPackage
ExcelPackage workbook = new ExcelPackage();
// Do something to populate your workbook
// Generate a new unique identifier against which the file can be stored
string handle = Guid.NewGuid().ToString()
using(MemoryStream memoryStream = new MemoryStream()){
workbook.SaveAs(memoryStream);
memoryStream.Position = 0;
TempData[handle] = memoryStream.ToArray();
}
// Note we are returning a filename as well as the handle
return new JsonResult() {
Data = new { FileGuid = handle, FileName = "TestReportOutput.xlsx" }
};
}
[HttpGet]
public virtual ActionResult Download(string fileGuid, string fileName)
{
if(TempData[fileGuid] != null){
byte[] data = TempData[fileGuid] as byte[];
return File(data, "application/vnd.ms-excel", fileName);
}
else{
// Problem - Log the error, generate a blank file,
// redirect to another controller action - whatever fits with your application
return new EmptyResult();
}
}
Given three tasks - FeedCat()
, SellHouse()
and BuyCar()
, there are two interesting cases: either they all complete synchronously (for some reason, perhaps caching or an error), or they don't.
Let's say we have, from the question:
Task<string> DoTheThings() {
Task<Cat> x = FeedCat();
Task<House> y = SellHouse();
Task<Tesla> z = BuyCar();
// what here?
}
Now, a simple approach would be:
Task.WhenAll(x, y, z);
but ... that isn't convenient for processing the results; we'd typically want to await
that:
async Task<string> DoTheThings() {
Task<Cat> x = FeedCat();
Task<House> y = SellHouse();
Task<Tesla> z = BuyCar();
await Task.WhenAll(x, y, z);
// presumably we want to do something with the results...
return DoWhatever(x.Result, y.Result, z.Result);
}
but this does lots of overhead and allocates various arrays (including the params Task[]
array) and lists (internally). It works, but it isn't great IMO. In many ways it is simpler to use an async
operation and just await
each in turn:
async Task<string> DoTheThings() {
Task<Cat> x = FeedCat();
Task<House> y = SellHouse();
Task<Tesla> z = BuyCar();
// do something with the results...
return DoWhatever(await x, await y, await z);
}
Contrary to some of the comments above, using await
instead of Task.WhenAll
makes no difference to how the tasks run (concurrently, sequentially, etc). At the highest level, Task.WhenAll
predates good compiler support for async
/await
, and was useful when those things didn't exist. It is also useful when you have an arbitrary array of tasks, rather than 3 discreet tasks.
But: we still have the problem that async
/await
generates a lot of compiler noise for the continuation. If it is likely that the tasks might actually complete synchronously, then we can optimize this by building in a synchronous path with an asynchronous fallback:
Task<string> DoTheThings() {
Task<Cat> x = FeedCat();
Task<House> y = SellHouse();
Task<Tesla> z = BuyCar();
if(x.Status == TaskStatus.RanToCompletion &&
y.Status == TaskStatus.RanToCompletion &&
z.Status == TaskStatus.RanToCompletion)
return Task.FromResult(
DoWhatever(a.Result, b.Result, c.Result));
// we can safely access .Result, as they are known
// to be ran-to-completion
return Awaited(x, y, z);
}
async Task Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
return DoWhatever(await x, await y, await z);
}
This "sync path with async fallback" approach is increasingly common especially in high performance code where synchronous completions are relatively frequent. Note it won't help at all if the completion is always genuinely asynchronous.
Additional things that apply here:
with recent C#, a common pattern is for the async
fallback method is commonly implemented as a local function:
Task<string> DoTheThings() {
async Task<string> Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
return DoWhatever(await a, await b, await c);
}
Task<Cat> x = FeedCat();
Task<House> y = SellHouse();
Task<Tesla> z = BuyCar();
if(x.Status == TaskStatus.RanToCompletion &&
y.Status == TaskStatus.RanToCompletion &&
z.Status == TaskStatus.RanToCompletion)
return Task.FromResult(
DoWhatever(a.Result, b.Result, c.Result));
// we can safely access .Result, as they are known
// to be ran-to-completion
return Awaited(x, y, z);
}
prefer ValueTask<T>
to Task<T>
if there is a good chance of things ever completely synchronously with many different return values:
ValueTask<string> DoTheThings() {
async ValueTask<string> Awaited(ValueTask<Cat> a, Task<House> b, Task<Tesla> c) {
return DoWhatever(await a, await b, await c);
}
ValueTask<Cat> x = FeedCat();
ValueTask<House> y = SellHouse();
ValueTask<Tesla> z = BuyCar();
if(x.IsCompletedSuccessfully &&
y.IsCompletedSuccessfully &&
z.IsCompletedSuccessfully)
return new ValueTask<string>(
DoWhatever(a.Result, b.Result, c.Result));
// we can safely access .Result, as they are known
// to be ran-to-completion
return Awaited(x, y, z);
}
if possible, prefer IsCompletedSuccessfully
to Status == TaskStatus.RanToCompletion
; this now exists in .NET Core for Task
, and everywhere for ValueTask<T>
in my case i just disabled //@RunWith(SpringRunner.class)
and there is no exception
I am guessing you are trying to mix Asp code and JS code and at some point it's breaking or not excusing the binding calls correctly.
Perhaps you can try using a delegate instead. It will cut out the complexity of when to bind the click event.
An example would be:
$('body').delegate('.menu li','click',function(){
var $li = $(this);
var shouldAddClass = $li.find('a[href^="www.xyz.com/link1"]').length != 0;
if(shouldAddClass){
$li.addClass('active');
}
});
See if that helps, it uses the Attribute Starts With Selector from jQuery.
Chi
You can use one and more echo statement inside href
<a href="profile.php?usr=<?php echo $_SESSION['firstname']."&email=". $_SESSION['email']; ?> ">Link</a>
link : "/profile.php?usr=firstname&email=email"
scala> lazy val lazyEight = {

you can use the pow method from the Math class. The following code will output 2 raised to 3 (8)
System.out.println(Math.pow(2, 3));
#include <algorithm> // std::transform
#include <iterator> // std::back_inserter
std::transform(
your_map.begin(),
your_map.end(),
std::back_inserter(your_values_vector),
[](auto &kv){ return kv.second;}
);
Sorry that I didn't add any explanation - I thought that code is so simple that is doesn't require any explanation. So:
transform( beginInputRange, endInputRange, outputIterator, unaryOperation)
this function calls unaryOperation
on every item from inputIterator
range (beginInputRange
-endInputRange
). The value of operation is stored into outputIterator
.
If we want to operate through whole map - we use map.begin() and map.end() as our input range. We want to store our map values into vector - so we have to use back_inserter on our vector: back_inserter(your_values_vector)
. The back_inserter is special outputIterator that pushes new elements at the end of given (as paremeter) collection.
The last parameter is unaryOperation - it takes only one parameter - inputIterator's value. So we can use lambda:
[](auto &kv) { [...] }
, where &kv is just a reference to map item's pair. So if we want to return only values of map's items we can simply return kv.second:
[](auto &kv) { return kv.second; }
I think this explains any doubts.
For those that run into this and end up on this answer, as I did, where they got this error during uninstall orupgrade and Ubuntu keeps failing to uninstall the previous because the service doesn't exist this one line will get you past that and allow the uninstall or upgrade to continue.

This is one alternative for achieving the same but it avoids race condition caused by having two distinct "check ..and.. create" operations.
package main
import (
"fmt"
"os"
)
func main() {
if err := ensureDir("/test-dir"); err != nil {
fmt.Println("Directory creation failed with error: " + err.Error())
os.Exit(1)
}
// Proceed forward
}
func ensureDir(dirName string) error {
err := os.MkdirAll(dirName, os.ModeDir)
if err == nil || os.IsExist(err) {
return nil
} else {
return err
}
}
Appears you can somewhat accomplish something similar with the Notification API. You can't control how long it stays visible (probably an OS preference of some kind--unless you specify requireInteraction true, then it stays up forever or until dismissed or until you close it), and it requires the user to click "allow notifications" (unfortunately) first, but here it is:
If you want it to close after 1s (all OS's leave it open 1s at least):
var notification = new Notification("Hi there!", {body: "some text"});
setTimeout(function() {notification.close()}, 1000);
If you wanted to show it longer than the "default" you could bind to the onclose callback and show another repeat notification I suppose, to replace it.
Ref: inspired by this answer, though that answer doesn't work in modern Chrome anymore, but the Notification API does.
If you want to pass an app-instance to others in Node-Typescript :
Option 1:
With the help of import
(when importing)
//routes.ts
import { Application } from "express";
import { categoryRoute } from './routes/admin/category.route'
import { courseRoute } from './routes/admin/course.route';
const routing = (app: Application) => {
app.use('/api/admin/category', categoryRoute)
app.use('/api/admin/course', courseRoute)
}
export { routing }
Then import it and pass app:
import express, { Application } from 'express';
const app: Application = express();
import('./routes').then(m => m.routing(app))
Option 2: With the help of class
// index.ts
import express, { Application } from 'express';
import { Routes } from './routes';
const app: Application = express();
const rotues = new Routes(app)
...
Here we will access the app in the constructor of Routes Class
// routes.ts
import { Application } from 'express'
import { categoryRoute } from '../routes/admin/category.route'
import { courseRoute } from '../routes/admin/course.route';
class Routes {
constructor(private app: Application) {
this.apply();
}
private apply(): void {
this.app.use('/api/admin/category', categoryRoute)
this.app.use('/api/admin/course', courseRoute)
}
}
export { Routes }
Recently I was playing with this method too. I wrote a memoized algorithm to calcualte Fibonacci numbers which could serve as another illustration on how to use the method.
We can start by defining a map and putting the values in it for the base cases, namely, fibonnaci(0)
and fibonacci(1)
:
private static Map<Integer,Long> memo = new HashMap<>();
static {
memo.put(0,0L); //fibonacci(0)
memo.put(1,1L); //fibonacci(1)
}
And for the inductive step all we have to do is redefine our Fibonacci function as follows:
public static long fibonacci(int x) {
return memo.computeIfAbsent(x, n -> fibonacci(n-2) + fibonacci(n-1));
}
As you can see, the method computeIfAbsent
will use the provided lambda expression to calculate the Fibonacci number when the number is not present in the map. This represents a significant improvement over the traditional, tree recursive algorithm.
I had to do this in order to keep an array value of (string) 0
$url = array_filter($data, function ($value) {
return (!empty($value) || $value === 0 || $value==='0');
});
If Khanh TO's solution caused UI issues for you (like it did for me) try using $timeout
to not update the attribute until it has been unchanged for 500ms.
var oldWidth = window.innerWidth;
$(window).on('resize.doResize', function () {
var newWidth = window.innerWidth,
updateStuffTimer;
if (newWidth !== oldWidth) {
$timeout.cancel(updateStuffTimer);
}
updateStuffTimer = $timeout(function() {
updateStuff(newWidth); // Update the attribute based on window.innerWidth
}, 500);
});
$scope.$on('$destroy',function (){
$(window).off('resize.doResize'); // remove the handler added earlier
});

You will need to use different IP addresses. The server, whether Apache or IIS, grabs the traffic based on the IP and Port, which ever they are bound to listen to. Once it starts listening, then it uses the headers, such as the server name to filter and determine what site is being accessed. You can't do it will simply changing the server name in the request
function auth (req, res, next) {
console.log(req.headers);
var authHeader = req.headers.authorization;
if (!authHeader) {
var err = new Error('You are not authenticated!');
res.setHeader('WWW-Authenticate', 'Basic');
err.status = 401;
next(err);
return;
}
var auth = new Buffer.from(authHeader.split(' ')[1], 'base64').toString().split(':');
var user = auth[0];
var pass = auth[1];
if (user == 'admin' && pass == 'password') {
next(); // authorized
} else {
var err = new Error('You are not authenticated!');
res.setHeader('WWW-Authenticate', 'Basic');
err.status = 401;
next(err);
}
}
app.use(auth);

You didn't specify your IDEA version. Before 9.0 use Build | Build Jars, in IDEA 9.0 use Project Structure | Artifacts.
You can check it from your command prompt by running gem help commands
and then selecting the proper command:
kirti@kirti-Aspire-5733Z:~$ gem help commands
GEM commands are:
build Build a gem from a gemspec
cert Manage RubyGems certificates and signing settings
check Check a gem repository for added or missing files
cleanup Clean up old versions of installed gems in the local
repository
contents Display the contents of the installed gems
dependency Show the dependencies of an installed gem
environment Display information about the RubyGems environment
fetch Download a gem and place it in the current directory
generate_index Generates the index files for a gem server directory
help Provide help on the 'gem' command
install Install a gem into the local repository
list Display gems whose name starts with STRING
lock Generate a lockdown list of gems
mirror Mirror all gem files (requires rubygems-mirror)
outdated Display all gems that need updates
owner Manage gem owners on RubyGems.org.
pristine Restores installed gems to pristine condition from
files located in the gem cache
push Push a gem up to RubyGems.org
query Query gem information in local or remote repositories
rdoc Generates RDoc for pre-installed gems
regenerate_binstubs Re run generation of executable wrappers for gems.
search Display all gems whose name contains STRING
server Documentation and gem repository HTTP server
sources Manage the sources and cache file RubyGems uses to
search for gems
specification Display gem specification (in yaml)
stale List gems along with access times
uninstall Uninstall gems from the local repository
unpack Unpack an installed gem to the current directory
update Update installed gems to the latest version
which Find the location of a library file you can require
yank Remove a specific gem version release from
RubyGems.org
For help on a particular command, use 'gem help COMMAND'.
Commands may be abbreviated, so long as they are unambiguous.
e.g. 'gem i rake' is short for 'gem install rake'.
kirti@kirti-Aspire-5733Z:~$
Now from the above I can see the command environment
is helpful. So I would do:
kirti@kirti-Aspire-5733Z:~$ gem help environment
Usage: gem environment [arg] [options]
Common Options:
-h, --help Get help on this command
-V, --[no-]verbose Set the verbose level of output
-q, --quiet Silence commands
--config-file FILE Use this config file instead of default
--backtrace Show stack backtrace on errors
--debug Turn on Ruby debugging
Arguments:
packageversion display the package version
gemdir display the path where gems are installed
gempath display path used to search for gems
version display the gem format version
remotesources display the remote gem servers
platform display the supported gem platforms
<omitted> display everything
Summary:
Display information about the RubyGems environment
Description:
The RubyGems environment can be controlled through command line arguments,
gemrc files, environment variables and built-in defaults.
Command line argument defaults and some RubyGems defaults can be set in a
~/.gemrc file for individual users and a /etc/gemrc for all users. These
files are YAML files with the following YAML keys:
:sources: A YAML array of remote gem repositories to install gems from
:verbose: Verbosity of the gem command. false, true, and :really are the
levels
:update_sources: Enable/disable automatic updating of repository metadata
:backtrace: Print backtrace when RubyGems encounters an error
:gempath: The paths in which to look for gems
:disable_default_gem_server: Force specification of gem server host on
push
<gem_command>: A string containing arguments for the specified gem command
Example:
:verbose: false
install: --no-wrappers
update: --no-wrappers
:disable_default_gem_server: true
RubyGems' default local repository can be overridden with the GEM_PATH and
GEM_HOME environment variables. GEM_HOME sets the default repository to
install into. GEM_PATH allows multiple local repositories to be searched for
gems.
If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
proxy server.
If you would like to push gems to a private gem server the RUBYGEMS_HOST
environment variable can be set to the URI for that server.
If you are packaging RubyGems all of RubyGems' defaults are in
lib/rubygems/defaults.rb. You may override these in
lib/rubygems/defaults/operating_system.rb
kirti@kirti-Aspire-5733Z:~$
Finally to show you what you asked, I would do:
kirti@kirti-Aspire-5733Z:~$ gem environment gemdir
/home/kirti/.rvm/gems/ruby-2.0.0-p0
kirti@kirti-Aspire-5733Z:~$ gem environment gempath
/home/kirti/.rvm/gems/ruby-2.0.0-p0:/home/kirti/.rvm/gems/ruby-2.0.0-p0@global
kirti@kirti-Aspire-5733Z:~$
In addition to anyListOf
above, you can always specify generics explicitly using this syntax:
when(mock.process(Matchers.<List<Bar>>any(List.class)));
Java 8 newly allows type inference based on parameters, so if you're using Java 8, this may work as well:
when(mock.process(Matchers.any()));
Remember that neither any()
nor anyList()
will apply any checks, including type or null checks. In Mockito 2.x, any(Foo.class)
was changed to mean "any instanceof
Foo", but any()
still means "any value including null
".
NOTE: The above has switched to ArgumentMatchers in newer versions of Mockito, to avoid a name collision with org.hamcrest.Matchers
. Older versions of Mockito will need to keep using org.mockito.Matchers
as above.
LDF holds the transaction log. If you set your backups correctly - it will be small. It it grows - you have a very common problem of setting database recovery mode to FULL and then forgetting to backup the transaction log (LDF file). Let me explain how to fix it.
Some would suggest to use SHRINKFILE to trim you log. Note that this is OK only as an exception. If you do it regularly, it defeats the purpose of FULL recovery model: first you go into trouble of saving every single change in the log, then you just dump it. Set recovery mode to SIMPLE instead.
There are no default constructors in Go, but you can declare methods for any type. You could make it a habit to declare a method called "Init". Not sure if how this relates to best practices, but it helps keep names short without loosing clarity.
package main
import "fmt"
type Thing struct {
Name string
Num int
}
func (t *Thing) Init(name string, num int) {
t.Name = name
t.Num = num
}
func main() {
t := new(Thing)
t.Init("Hello", 5)
fmt.Printf("%s: %d\n", t.Name, t.Num)
}
The result is:
Hello: 5
when you are in a terminal window, command + n => opens a new terminal and command + t => opens a new tab in current terminal window
As several answer explained the you should run:
npm i
BUT if it does not solve...
Check the version of your npm
executable. (For me it was 3.x.x which doesn't uses the package-lock.json
(at all))
npm -v
It should be at least 5.x.x (which introduced the package-lock.json file.)
To update npm
on Linux, follow these instructions.
For more details about package files, please read this medium story.
THE CORRECT WAY ************************ THE CORRECT WAY
while($rows[] = mysqli_fetch_assoc($result));
array_pop($rows); // pop the last row off, which is an empty row
Another way is:
f = open("|ls")
foo = f.read()
Note that's the "pipe" character before "ls" in open. This can also be used to feed data into the programs standard input as well as reading its standard output.
For better performance you should use:
var numItems = $('div.item').length;
Since it will only look for the div
elements in DOM
and will be quick.
Suggestion: using size()
instead of length
property means one extra step in the processing since SIZE()
uses length
property in the function definition and returns the result.
This will get you close, the add button has been removed out of the table so you might want to consider this...
<script type="text/javascript">
$(document).ready(function() {
$("#add").click(function() {
$('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last');
return false;
});
});
</script>
HTML markup looks like this
<a id="add">+</a></td>
<table id="mytable" width="300" border="1" cellspacing="0" cellpadding="2">
<tbody>
<tr>
<td>Name</td>
</tr>
<tr class="person">
<td><input type="text" name="name" id="name" /></td>
</tr>
</tbody>
</table>
EDIT To empty a value of a textbox after insert..
$('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last');
$('#mytable tbody>tr:last #name').val('');
return false;
EDIT2 Couldn't help myself, to reset all dropdown lists in the inserted TR you can do this
$("#mytable tbody>tr:last").each(function() {this.reset();});
I will leave the rest to you!
You have to change the file from .html to .php.
and add this following line
header('Content-Type: text/html; charset=utf-8');
using numpy and list comprehension you can do the
import numpy as np
[num for num in np.arange(1,101) if (num%4 == 1 or num%4 == 2)]
There is a single quote in $submitsubject
or $submit_message
Why is this a problem?
The single quote char terminates the string in MySQL and everything past that is treated as a sql command. You REALLY don't want to write your sql like that. At best, your application will break intermittently (as you're observing) and at worst, you have just introduced a huge security vulnerability.
Imagine if someone submitted '); DROP TABLE private_messages;
in submit message.
Your SQL Command would be:
INSERT INTO private_messages (to_id, from_id, time_sent, subject, message)
VALUES('sender_id', 'id', now(),'subjet','');
DROP TABLE private_messages;
Instead you need to properly sanitize your values.
AT A MINIMUM you must run each value through mysql_real_escape_string()
but you should really be using prepared statements.
If you were using mysql_real_escape_string()
your code would look like this:
if($_POST['submit_message']){
if($_POST['form_subject']==""){
$submit_subject="(no subject)";
}else{
$submit_subject=mysql_real_escape_string($_POST['form_subject']);
}
$submit_message=mysql_real_escape_string($_POST['form_message']);
$sender_id = mysql_real_escape_string($_POST['sender_id']);
Here is a great article on prepared statements and PDO.
I'd use JSON as the format and Ajax (really XMLHttpRequest) as the client->server mechanism.
If you want to view the progress of the dump try this:
pv -i 1 -p -t -e /path/to/sql/dump | mysql -u USERNAME -p DATABASE_NAME
You'll of course need 'pv' installed. This command works only on *nix.
Some frameworks are using this header to detect xhr requests e.g. grails spring security is using this header to identify xhr request and give either a json response or html response as response.
Most Ajax libraries (Prototype, JQuery, and Dojo as of v2.1) include an X-Requested-With header that indicates that the request was made by XMLHttpRequest instead of being triggered by clicking a regular hyperlink or form submit button.

I can't comment on the accepted answer, due to low reputation. However, I would like to add, this behavior is by design. The NodeManager is killing your container. It sounds like you are trying to use hadoop streaming which is running as a child process of the map-reduce task. The NodeManager monitors the entire process tree of the task and if it eats up more memory than the maximum set in mapreduce.map.memory.mb or mapreduce.reduce.memory.mb respectively, we would expect the Nodemanager to kill the task, otherwise your task is stealing memory belonging to other containers, which you don't want.

Check out the following links which may help you
Best examples are provided in the below links, which you can refactor to meet your requirements.
//start the program
var express = require('express');
var app = express();
app.get('/', function (req, res) {
var sql = require("mssql");
// config for your database
var config = {
user: 'datapullman',
password: 'system',
server: 'localhost',
database: 'chat6'
};
// connect to your database
sql.connect(config, function (err) {
if (err) console.log(err);
// create Request object
var request = new sql.Request();
// query to the database and get the records
request.query("select * From emp", function (err, recordset) {
if (err) console.log(err)
// send records as a response
res.send(recordset);
});
});
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
//create a table as emp in a database (i have created as chat6)
// programs ends here
//save it as app.js and run as node app.js //open in you browser as localhost:5000
The orderBy
method requires either two strings or an Expr\OrderBy
object. If you want to add multiple order declarations, the correct thing is to use addOrderBy
method, or instantiate an OrderBy
object and populate it accordingly:
# Inside a Repository method:
$myResults = $this->createQueryBuilder('a')
->addOrderBy('a.column1', 'ASC')
->addOrderBy('a.column2', 'ASC')
->addOrderBy('a.column3', 'DESC')
;
# Or, using a OrderBy object:
$orderBy = new OrderBy('a.column1', 'ASC');
$orderBy->add('a.column2', 'ASC');
$orderBy->add('a.column3', 'DESC');
$myResults = $this->createQueryBuilder('a')
->orderBy($orderBy)
;
Instead of mocking concrete class you should mock that class interface. Extract interface from XmlCupboardAccess class
public interface IXmlCupboardAccess
{
bool IsDataEntityInXmlCupboard(string dataId, out string nameInCupboard, out string refTypeInCupboard, string nameTemplate = null);
}
And instead of
private Mock<XmlCupboardAccess> _xmlCupboardAccess = new Mock<XmlCupboardAccess>();
change to
private Mock<IXmlCupboardAccess> _xmlCupboardAccess = new Mock<IXmlCupboardAccess>();
Use the createFromFormat
method:
$start_date = DateTime::createFromFormat("U", $dbResult->db_timestamp);
UPDATE
I now recommend the use of Carbon
Create a File
object, passing the directory path to the constructor. Use the listFiles()
to retrieve an array of File
objects for each file in the directory, and then call the getName()
method to get the filename.
List<String> results = new ArrayList<String>();
File[] files = new File("/path/to/the/directory").listFiles();
//If this pathname does not denote a directory, then listFiles() returns null.
for (File file : files) {
if (file.isFile()) {
results.add(file.getName());
}
}
Woff is a compressed (zipped) form of the TrueType - OpenType font. It is small and can be delivered over the network like a graphic file. Most importantly, this way the font is preserved completely including rendering rule tables that very few people care about because they use only Latin script.
Take a look at [dead URL removed]. The font you see is an experimental web delivered smartfont (woff) that has thousands of combined characters making complex shapes. The underlying text is simple Latin code of romanized Singhala. (Copy and paste to Notepad and see).
Only woff can do this because nobody has this font and yet it is seen anywhere (Mac, Win, Linux and even on smartphones by all browsers except by IE. IE does not have full support for Open Types).
SSIS doesn't implicitly convert data types, so you need to do it explicitly. The Excel connection manager can only handle a few data types and it tries to make a best guess based on the first few rows of the file. This is fully documented in the SSIS documentation.
You have several options:
INSERT
into the real destination table using CAST
or CONVERT
to convert the dataYou might also want to note the comments in the Import Wizard documentation about data type mappings.
if you want to use parentheses in laravel 4 and don't forget return
In Laravel 4 (at least) you need to use $a, $b in parentheses as in the example
$a = 1;
$b = 1;
$c = 1;
$d = 1;
Model::where(function ($query) use ($a, $b) {
return $query->where('a', '=', $a)

This was not what I was expecting as a solution (though it is a legitimate use case). My requirement was to allow an existing buggy client (a mobile app which already released) to use alternate names.
The solution lies in providing a separate setter method like this:
@JsonSetter( "r" )
public void alternateSetRed( byte red ) {
this.red = red;
}
To accomplish that, you can use the two events onfocus and onblur:
<input type="text" name="theName" value="DefaultValue"
onblur="if(this.value==''){ this.value='DefaultValue'; this.style.color='#BBB';}"
onfocus="if(this.value=='DefaultValue'){ this.value=''; this.style.color='#000';}"
style="color:#BBB;" />

Or, if you're connected to a domain:

Just managed to sort this finally after hours. The www subdomain was pointing to Sites, but the front end wasn't showing me that.
After taking the plunge and setting the CNAME to gwh.google.com, and enabling / disabling Sites a couple of times (see the comment from Rodrigo Moraes on http://groups.google.com/group/google-appengine/web/deleting-existing-www-mapping-from-google-apps) I was able to set the Sites address to use the www subdomain.
I was then able to change it away from using the www subdomain, at which point the appengine app allowed me to specify the www subdomain.
That is one dirty fix - basically turning on and off Sites until it works!

In an interface all methods must be only definitions, not single one should be implemented.
But in an abstract class there must an abstract method with only definition, but other methods can be also in the abstract class with implementation...

Right now (11 Jul 2015) this solution is still working (jquery 2.1.4); in my opinion, it is the best one to pick up.
You need to convert the date into a readable value. You may use strftime() or date().
Try this:
$effectiveDate = strtotime("+3 months", strtotime($effectiveDate));
$effectiveDate = strftime ( '%Y-%m-%d' , $effectiveDate );
echo $effectiveDate;
This should work. I like using strftime better as it can be used for localization you might want to try it.

Adding up on EJP's answer; use this for more fluidity. Make sure you don't put his code inside a bigger try catch with more code between the .read and the catch block, it may return an exception and jump all the way to the outer catch block, safest bet is to place EJPS's while loop inside a try catch, and then continue the code after it, like:
int count;
byte[] bytes = new byte[4096];
try {
while ((count = is.read(bytes)) > 0) {
System.out.println(count);
bos.write(bytes, 0, count);
}
} catch ( Exception e )
{
//It will land here....
}
// Then continue from here

An established connection was aborted by the software in your host machine
That is a boiler-plate error message, it comes out of Windows. The underlying error code is WSAECONNABORTED. Which really doesn't mean more than "connection was aborted". You have to be a bit careful about the "your host machine" part of the phrase. In the vast majority of Windows application programs, it is indeed the host that the desktop app is connected to that aborted the connection. Usually a server somewhere else.
The roles are reversed however when you implement your own server. Now you need to read the error message as "aborted by the application at the other end of the wire". Which is of course not uncommon when you implement a server, client programs that use your server are not unlikely to abort a connection for whatever reason. It can mean that a fire-wall or a proxy terminated the connection but that's not very likely since they typically would not allow the connection to be established in the first place.
You don't really know why a connection was aborted unless you have insight what is going on at the other end of the wire. That's of course hard to come by. If your server is reachable through the Internet then don't discount the possibility that you are being probed by a port scanner. Or your customers, looking for a game cheat.
Extending @Hrvoje Hudo's answer...
Code:
using System;
using System.Runtime.Caching;
public class InMemoryCache : ICacheService
{
public TValue Get<TValue>(string cacheKey, int durationInMinutes, Func<TValue> getItemCallback) where TValue : class
{
TValue item = MemoryCache.Default.Get(cacheKey) as TValue;
if (item == null)
{
item = getItemCallback();
MemoryCache.Default.Add(cacheKey, item, DateTime.Now.AddMinutes(durationInMinutes));
}
return item;
}
public TValue Get<TValue, TId>(string cacheKeyFormat, TId id, int durationInMinutes, Func<TId, TValue> getItemCallback) where TValue : class
{
string cacheKey = string.Format(cacheKeyFormat, id);
TValue item = MemoryCache.Default.Get(cacheKey) as TValue;
if (item == null)
{
item = getItemCallback(id);
MemoryCache.Default.Add(cacheKey, item, DateTime.Now.AddMinutes(durationInMinutes));
}
return item;
}
}
interface ICacheService
{
TValue Get<TValue>(string cacheKey, Func<TValue> getItemCallback) where TValue : class;
TValue Get<TValue, TId>(string cacheKeyFormat, TId id, Func<TId, TValue> getItemCallback) where TValue : class;
}
Examples
Single item caching (when each item is cached based on its ID because caching the entire catalog for the item type would be too intensive).
Product product = cache.Get("product_{0}", productId, 10, productData.getProductById);
Caching all of something
IEnumerable<Categories> categories = cache.Get("categories", 20, categoryData.getCategories);
Why TId
The second helper is especially nice because most data keys are not composite. Additional methods could be added if you use composite keys often. In this way you avoid doing all sorts of string concatenation or string.Formats to get the key to pass to the cache helper. It also makes passing the data access method easier because you don't have to pass the ID into the wrapper method... the whole thing becomes very terse and consistant for the majority of use cases.
With .NET Core 2.2, and in the simplest way possible...
public IActionResult Index([FromServices] IConfiguration config)
{
var myValue = config.GetValue<string>("MyKey");
}
appsettings.json
is automatically loaded and available through either constructor or action injection, and there's a GetSection
method on IConfiguration
as well. There isn't any need to alter Startup.cs
or Program.cs
if all you need is appsettings.json
.
It's surprising to see that nobody mentioned the native JS way to do this..
Just access the children
property of the parent element. It will return a live HTMLCollection of children elements which can be accessed by an index. If you want to get the second child:
parentElement.children[1];
In your case, something like this could work: (example)
var secondChild = document.querySelector('.parent').children[1];
console.log(secondChild); // <td>element two</td>
<table>
<tr class="parent">
<td>element one</td>
<td>element two</td>
</tr>
</table>
You can also use a combination of CSS3 selectors / querySelector()
and utilize :nth-of-type()
. This method may work better in some cases, because you can also specifiy the element type, in this case td:nth-of-type(2)
(example)
var secondChild = document.querySelector('.parent > td:nth-of-type(2)');
console.log(secondChild); // <td>element two</td>
The accept attribute specifies a comma-separated list of content types (MIME types) that the target of the form will process correctly. Unfortunately this attribute is ignored by all the major browsers, so it does not affect the browser's file dialog in any way.

I know this already has a chosen answer - but I wanted to toss in my two cents. I have a databound dropdown list:
<asp:DropDownList
id="country"
runat="server"
CssClass="selectOne"
DataSourceID="country_code"
DataTextField="Name"
DataValueField="CountryCode_PK"
></asp:DropDownList>
<asp:SqlDataSource
id="country_code"
runat="server"
ConnectionString="<%$ ConnectionStrings:DBConnectionString %>"
SelectCommand="SELECT CountryCode_PK, CountryCode_PK + ' - ' + Name AS N'Name' FROM TBL_Country ORDER BY CountryCode_PK"
></asp:SqlDataSource>
In the codebehind, I have this - (which selects United States by default):
if (this.IsPostBack)
{
//handle posted data
}
else
{
country.SelectedValue = "US";
}
The page initially loads based on the 'US' value rather than trying to worry about a selectedIndex (what if another item is added into the data table - I don't want to have to re-code)
Recompiling did the trick for me!
You can try this-
mysql> select @@datadir;
PS- It works on every platform.
The first numbers of the credit card can be used to approximate the vendor:
Just make sure you've downloaded Binary zip archive(apache-maven-3.5.0-bin.zip) instead of Source zip archive. Then add the bin directory of the created directory apache-maven-3.5.0 to the PATH environment variable.
Short answer is that you don't 'decrypt' the password (because it's not encrypted - it's hashed).
The long answer is that you shouldn't send the user their password by email, or any other way. If the user has forgotten their password, you should send them a password reset email, and allow them to change their password on your website.
Laravel has most of this functionality built in (see the Laravel documentation - I'm not going to replicate it all here. Also available for versions 4.2 and 5.0 of Laravel).
For further reading, check out this 'blogoverflow' post: Why passwords should be hashed.
Steps to convert .py to .exe in Python 3.6
pip install cx_Freeze
.pip install idna
..py
program named myfirstprog.py
.setup.py
on the current directory of your script.setup.py
file, copy the code below and save it.python setup.py build
build
. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.See the original script in my blog.
setup.py:
from cx_Freeze import setup, Executable
base = None
executables = [Executable("myfirstprog.py", base=base)]
packages = ["idna"]
options = {
'build_exe': {
'packages':packages,
},
}
setup(
name = "<any name>",
options = options,
version = "<any number>",
description = '<any description>',
executables = executables
)
EDIT:
myfirstprog.py
you should put your .py
extension file name as created in step 4;import
ed package in your .py
into packages
list (ex: packages = ["idna", "os","sys"]
)any name, any number, any description
in setup.py
file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = ''
)import
ed packages must be installed before you start step 8.Also be sure to check out the OWASP Top 10 List for a categorization of all the main attack vectors/vulnerabilities.
These things are fascinating to read about. Learning to think like an attacker will train you of what to think about as you're writing your own code.
There is a better, and simpler, solution than the one given by John Vinyard. Use NullLocator
:
import matplotlib.pyplot as plt
plt.plot(range(10))
plt.gca().xaxis.set_major_locator(plt.NullLocator())
plt.show()
plt.savefig('plot')
Hope that helps.
To check that the file you're trying to open actually exists, you can change directories in terminal using cd
. To change to ~/Desktop/sass/css
: cd ~/Desktop/sass/css
. To see what files are in the directory: ls
.
If you want information about either of those commands, use the man
page: man cd
or man ls
, for example.
Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.
On Mac OS X, you can also use open
to open a finder window: open .
will open the current directory in finder. (open ~/Desktop/sass/css
will open the ~/Desktop/sass/css
).
paste your .html file in assets folder of your project folder. and create an xml file in layout folder with the fol code: my.xml:
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
add fol code in activity
setContentView(R.layout.my);
WebView mWebView = null;
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("file:///android_asset/new.html"); //new.html is html file name.
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission). This has been confirmed by Facebook as 'by design'.
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.
Use Apache Commons (IO and Lang) for simple/common things like this.
Imports:
import org.apache.commons.io.FileUtils;
import org.apache.commons.lang3.ArrayUtils;
Code:
String contents = FileUtils.readFileToString(new File("path/to/your/file.txt"));
String[] array = ArrayUtils.toArray(contents.split(" "));
Done.
$color = sprintf("#%06x",rand(0,16777215));
I was able to slightly improve Jai's answer to work in the case of you having more than one button dropdown with a pretty good presentation that works with bootstrap 3:
Code for The Button
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Option: <span class="selection">Option 1</span><span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Option 1</a></li>
<li><a href="#">Option 2</a></li>
<li><a href="#">Option 3</a></li>
</ul>
</div>
JQuery Snippet
$(".dropdown-menu li a").click(function(){
$(this).parents(".btn-group").find('.selection').text($(this).text());
$(this).parents(".btn-group").find('.selection').val($(this).text());
});
I also added a 5px margin-right to the "selection" class.
For me i tried everything on here and eventually it boiled down to a corporate proxy that kept on resetting the INET Settings.
I worked my way down the list of suggestions but in the end turned out to be the proxy settings. I had hunch about it but i wanted to be thorogh about it before going to 'IT' and saying can i have local bindows proxy settings override please?
I asked for the proxy management software to be removed and then within a second fiddler started working. If you cannot override the proxy settings in Internet Properties then fiddler will never work.
I assume you want to make modal use as much screen space as possible on phones. I've made a plugin to fix this UX problem of Bootstrap modals on mobile phones, you can check it out here - https://github.com/keaukraine/bootstrap-fs-modal
All you will need to do is to apply modal-fullscreen
class and it will act similar to native screens of iOS/Android.
I have 2.22 installed and this worked..
git stash pop --index 1
This is how I do it:

padding: 0;
width: 100%;
height: 100%;
display: table
}
#content {
display: table-cell;
text-align: center;
vertical-align: middle
}
HTML:
<div id="content">

In addition to Delan Azabani's answer, I like to share my console.js
, and I use for the same purpose. I create a noop console using an array of function names, what is in my opinion a very convenient way to do this, and I took care of Internet Explorer, which has a console.log
function, but no console.debug
:
// Create a noop console object if the browser doesn't provide one...
if (!window.console){
window.console = {};
}
// Internet Explorer has a console that has a 'log' function, but no 'debug'. To make console.debug work in Internet Explorer,
// We just map the function (extend for info, etc. if needed)
else {
if (!window.console.debug && typeof window.console.log !== 'undefined') {
window.console.debug = window.console.log;
}
}
// ... and create all functions we expect the console to have (taken from Firebug).
var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
"group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];
for (var i = 0; i < names.length; ++i){
if(!window.console[names[i]]){
window.console[names[i]] = function() {};
}
}
Unless you are subtracting dates on same browser client and don't care about edge cases like day light saving time changes, you are probably better off using moment.js which offers powerful localized APIs. For example, this is what I have in my utils.js:
subtractDates: function(date1, date2) {
return moment.subtract(date1, date2).milliseconds();
},
millisecondsSince: function(dateSince) {
return moment().subtract(dateSince).milliseconds();
},
When creating constants in a jar file, it is often helpful to let users extend enum values. We used enums for PropertyFile keys and got stuck because nobody could add any new ones! Below would have worked much better.
Given:
public interface Color {
String fetchName();
}
and:
public class MarkTest {
public static void main(String[] args) {
MarkTest.showColor(Colors.BLUE);
MarkTest.showColor(MyColors.BROWN);
}
private static void showColor(Color c) {
System.out.println(c.fetchName());
}
}
one could have one enum in the jar:
public enum Colors implements Color {
BLUE, RED, GREEN;
@Override
public String fetchName() {
return this.name();
}
}
and a user could extend it to add his own colors:
public enum MyColors implements Color {
BROWN, GREEN, YELLOW;
@Override
public String fetchName() {
return this.name();
}
}
I had the same error. Resizing the images resolved the issue. However, I used online tools to resize the images because using pillow to resize them did not solve my problem.
How about mkString ?
theStrings.mkString(",")
A variant exists in which you can specify a prefix and suffix too.
See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.
Another Solution for detecting Shift+Enter Key with Angular2+
Inside Component.html
<input type="text" (keydown.shift.enter)="newLine($event)">
Inside Component.ts
newLine(event){
if(event.keyCode==13 && event.shiftKey){
alert('Shift+Enter key Pressed');
}
}
If you read the performance and benchmark stats on this website, you'll see that the fastest way to read (because reading, writing, and processing are all different) a text file is the following snippet of code:
using (StreamReader sr = File.OpenText(fileName))
{
string s = String.Empty;
while ((s = sr.ReadLine()) != null)
{
//do your stuff here
}
}
All up about 9 different methods were bench marked, but that one seem to come out ahead the majority of the time, even out performing the buffered reader as other readers have mentioned.
They're also useful when you need several "constructors" with the same parameter type but with different behavior.
If you open the dropdown for the Text
property in Visual Studio, you can use the enter key to split lines. This will obviously only work for static text unless you know the maximum dimensions of dynamic text.
I suggest to add the '+' operator as follows:
list = list + ['foo']
Hope it helps!
./script.sh | sort -u
This is the same as monoxide's answer, but a bit more concise.
At the moment I'm selecting like this:
$('a[data-attribute=true]')
Which seems to work just fine, but it would be nice if jQuery was able to select by that attribute without the 'data-' prefix.
I haven't tested this with data added to elements via jQuery dynamically, so that could be the downfall of this method.
If you need to change the background colour of the navbar, you can do the following:

And to change the text:

This Kotlin state machine library has PlantUML export feature, it is not integrated with Android Studio but it is easy to visualize state machine structure on PlantUML web site.
That’s probably everyone’s first thought. But it’s a little bit more difficult. See Chris Shiflett’s article SERVER_NAME
Versus HTTP_HOST
.
It seems that there is no silver bullet. Only when you force Apache to use the canonical name you will always get the right server name with SERVER_NAME
.
So you either go with that or you check the host name against a white list:
$allowed_hosts = array('foo.example.com', 'bar.example.com');
if (!isset($_SERVER['HTTP_HOST']) || !in_array($_SERVER['HTTP_HOST'], $allowed_hosts)) {
header($_SERVER['SERVER_PROTOCOL'].' 400 Bad Request');
exit;
}
You could load the external page with jquery:
<script>$("#testLoad").load("http://www.somesite.com/somepage.html");</script> <div id="testLoad"></div> //would this help
An HttpHandler
(or IHttpHandler
) is basically anything that is responsible for serving content. An ASP.NET page (aspx) is a type of handler.
You might write your own, for example, to serve images etc from a database rather than from the web-server itself, or to write a simple POX service (rather than SOAP/WCF/etc)
Set texts with different sizes and styles, and size and style for texts from cells ( with Range)
Sub EmailManuellAbsenden()

Dim ghNewBody As String
Set ghApp = CreateObject("Outlook.Application")
With ghApp.CreateItem(0)
.To = Range("B2")
.CC = Range("B3")
.Subject = Range("B4")
.GetInspector.Display
ghOldBody = .htmlBody
ghNewBody = "<font style=""font-family: Calibri; font-size: 11pt;""/font>" & _
"<font style=""font-family: Arial; font-size: 14pt;"">Arial Text 14</font>" & _
Range("B5") & "<br>" & _
Range("B6") & "<br>" & _
"<font style=""font-family: Chiller; font-size: 21pt;"">Ciller 21</font>" &

.htmlBody = ghNewBody & ghOldBody
End With
End Sub
'Fill B2 to B6 with some letters for testing
'"<font style=""font-family: Calibri; font-size: 15pt;""/font>" = works for all Range Objekts
There is another answer here that also fits the authors request: 'compile-time' way to get all property names defined interface
If you use the plugin ts-transformer-keys and an Interface to your class you can get all the keys for the class.
But if you're using Angular or React then in some scenarios there is additional configuration necessary (webpack and typescript) to get it working: https://github.com/kimamula/ts-transformer-keys/issues/4
I would like to share 2 tips: (tip 1) create a csv file (tip 2) Load rows from a csv file into a table.
====[ (tip 1) SQLPLUS to create a csv file form an Oracle table ]====
I use SQLPLUS with the following commands:
set markup csv on
set lines 1000
set pagesize 100000 linesize 1000
set feedback off
set trimspool on
spool /MyFolderAndFilename.csv
Select * from MYschema.MYTABLE where MyWhereConditions ;
spool off
exit
====[tip 2 SQLLDR to load a csv file into a table ]====
I use SQLLDR and a csv ( comma separated ) file to add (APPEND) rows form the csv file to a table. the file has , between fields text fields have " before and after the text CRITICAL: if last column is null there is a , at the end of the line
Example of data lines in the csv file:
11,"aa",1001
22,"bb',2002
33,"cc",
44,"dd",4004
55,"ee',
This is the control file:
LOAD DATA
APPEND
INTO TABLE MYSCHEMA.MYTABLE
fields terminated by ',' optionally enclosed by '"'
TRAILING NULLCOLS
(
CoulmnName1,
CoulmnName2,
CoulmnName3
)
This is the command to execute sqlldr in Linux. If you run in Windows use \ instead of / c:
sqlldr userid=MyOracleUser/MyOraclePassword@MyOracleServerIPaddress:port/MyOracleSIDorService DATA=datafile.csv CONTROL=controlfile.ctl LOG=logfile.log BAD=notloadedrows.bad
Good luck !
As the rank doesn't depend at all from the contacts
RANKED_RSLTS
QRY_ID | RES_ID | SCORE | RANK
-------------------------------------
A | 1 | 15 | 3
A | 2 | 32 | 1
A | 3 | 29 | 2
C | 7 | 61 | 1
C | 9 | 30 | 2
Thus :
SELECT
C.*
,R.SCORE
,MYRANK
FROM CONTACTS C LEFT JOIN
(SELECT *,
MYRANK = RANK() OVER (PARTITION BY QRY_ID ORDER BY SCORE DESC)
FROM RSLTS) R
ON C.RES_ID = R.RES_ID
AND C.QRY_ID = R.QRY_ID
To quote the documentation:
Key words and unquoted identifiers are case insensitive. Therefore:
UPDATE MY_TABLE SET A = 5;
can equivalently be written as:
uPDaTE my_TabLE SeT a = 5;
You could also write it using quoted identifiers:
UPDATE "my_table" SET "a" = 5;
Quoting an identifier makes it case-sensitive, whereas unquoted names are always folded to lower case (unlike the SQL standard where unquoted names are folded to upper case). For example, the identifiers FOO
, foo
, and "foo"
are considered the same by PostgreSQL, but "Foo"
and "FOO"
are different from these three and each other.
If you want to write portable applications you are advised to always quote a particular name or never quote it.
I don't think it will make a significant difference in compile time but #pragma once
is very well supported across compilers but not actually part of the standard. The preprocessor may be a little faster with it as it is more simple to understand your exact intent.
#pragma once
is less prone to making mistakes and it is less code to type.
To speed up compile time more just forward declare instead of including in .h files when you can.
I prefer to use #pragma once
.
See this wikipedia article about the possibility of using both.
If using TFS, performing a Get latest (recursive) doesn't always work. Instead, I force a get latest by clicking Source control => Get specific version then clicking both boxes. This tends to work.
If it still doesn't work then deleting the suo file (usually found in the same place as the solution) forces visual studio to get all the files from the source (and subsequently rebuild the suo file).
If that doesn't work then try closing all your open files and closing Visual studio. When you next open Visual studio it should be fixed. There is a resharper bug that is resolved this way.

I've refactored your code a bit, this should work:
jQuery("#loadActive").click(writeData);
function writeData() {
jQuery("#chatTickets input:radio").attr('disabled',true);
}
If there are more than two radio buttons on your form, you'll have to modify the selector, for example, you can use the starts with attribute filter to pick out the radios whose ID starts with ticketID
:
function writeData() {
jQuery("#chatTickets input[id^=ticketID]:radio").attr('disabled',true);
}

When you look at the '=' operator in Python, don't think in terms of assignment. You don't assign things, you bind them. = is a binding operator.
So in your code, you are giving the value 1 a name: a. Then, you are giving the value in 'a' a name: b. Then you are binding the value 2 to the name 'a'. The value bound to b doesn't change in this operation.
Coming from C-like languages, this can be confusing, but once you become accustomed to it, you find that it helps you to read and reason about your code more clearly: the value which has the name 'b' will not change unless you explicitly change it. And if you do an 'import this', you'll find that the Zen of Python states that Explicit is better than implicit.
Note as well that functional languages such as Haskell also use this paradigm, with great value in terms of robustness.
Map<String, String> map = new HashMap<String, String>();
map.put("key1", "value1");
map.put("key2", "value2");
Object[][] twoDarray = new Object[map.size()][2];
Object[] keys = map.keySet().toArray();
Object[] values = map.values().toArray();
for (int row = 0; row < twoDarray.length; row++) {
twoDarray[row][0] = keys[row];
twoDarray[row][1] = values[row];
}
// Print out the new 2D array
for (int i = 0; i < twoDarray.length; i++) {
for (int j = 0; j < twoDarray[i].length; j++) {
System.out.println(twoDarray[i][j]);
}
}

This can be done using the tag <ScrollView>
. For ScrollView, one thing you have to remind that, ScrollView must have a single child.
If you want your full layout to be scrollable then add <ScrollView>
at the top. Check the example given below.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Content here -->
</LinearLayout>
</ScrollView>
But if you want some part of your layout to be scrollable then add <ScrollView>
within that part. Check the example given below.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="400dp">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Content here -->
</LinearLayout>
</ScrollView>
</LinearLayout>
Every method (other than a constructor) must have a return type.

If your column with DATE datatype has value like below : -
value in column : 10-NOV-2005 06:31:00
Then, You can Use TRUNC function in select query to convert your date-time value to only date like - DD/MM/YYYY or DD-MON-YYYY
select TRUNC(column_1) from table1;
result : 10-NOV-2005
You will see above result - Provided that NLS_DATE_FORMAT is set as like below :-
Alter session NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';
When you modify a file in your repository, the change is initially unstaged. In order to commit it, you must stage it—that is, add it to the index—using git add
. When you make a commit, the changes that are committed are those that have been added to the index.
git reset
changes, at minimum, where the current branch (HEAD
) is pointing. The difference between --mixed
and --soft
is whether or not your index is also modified. So, if we're on branch master
with this series of commits:
- A - B - C (master)
HEAD
points to C
and the index matches C
.
When we run git reset --soft B
, master
(and thus HEAD
) now points to B
, but the index still has the changes from C
; git status
will show them as staged. So if we run git commit
at this point, we'll get a new commit with the same changes as C
.
Okay, so starting from here again:
- A - B - C (master)
Now let's do git reset --mixed B
. (Note: --mixed
is the default option). Once again, master
and HEAD
point to B, but this time the index is also modified to match B
. If we run git commit
at this point, nothing will happen since the index matches HEAD
. We still have the changes in the working directory, but since they're not in the index, git status
shows them as unstaged. To commit them, you would git add
and then commit as usual.
And finally, --hard
is the same as --mixed
(it changes your HEAD
and index), except that --hard
also modifies your working directory. If we're at C
and run git reset --hard B
, then the changes added in C
, as well as any uncommitted changes you have, will be removed, and the files in your working copy will match commit B
. Since you can permanently lose changes this way, you should always run git status
before doing a hard reset to make sure your working directory is clean or that you're okay with losing your uncommitted changes.
And finally, a visualization:
If you want it to stop looking after a while (timeout) then the following jQuery will work. It will time out after 10sec. I needed to use this code rather than pure JS because I needed to select an input via name and was having trouble implementing some of the other solutions.
// Wait for element to exist.
function imageLoaded(el, cb,time) {
if ($(el).length) {
// Element is now loaded.
cb($(el));
var imageInput = $('input[name=product\\[image_location\\]]');
console.log(imageInput);
} else if(time < 10000) {
// Repeat every 500ms.
setTimeout(function() {
time = time+500;
imageLoaded(el, cb, time)
}, 500);
}
};
var time = 500;
imageLoaded('input[name=product\\[image_location\\]]', function(el) {
//do stuff here
},time);
Filter is just that. It filters out the elements of a list. You can see the definition mentions the same(in the official docs link I mentioned before). Whereas, list comprehension is something that produces a new list after acting upon something on the previous list.(Both filter and list comprehension creates new list and not perform operation in place of the older list. A new list here is something like a list with, say, an entirely new data type. Like converting integers to string ,etc)
In your example, it is better to use filter than list comprehension, as per the definition. However, if you want, say other_attribute from the list elements, in your example is to be retrieved as a new list, then you can use list comprehension.
return [item.other_attribute for item in my_list if item.attribute==value]
This is how I actually remember about filter and list comprehension. Remove a few things within a list and keep the other elements intact, use filter. Use some logic on your own at the elements and create a watered down list suitable for some purpose, use list comprehension.
Remove the slashes:
String json = {"phonetype":"N95","cat":"WP"};

JSONObject obj = new JSONObject(json);
Log.d("My App", obj.toString());
} catch (Throwable t) {
Log.e("My App", "Could not parse malformed JSON: \"" + json + "\"");
}

What is the exact contents you are passing into $html_brand?
If it is has an invalid URL syntax, you will very likely get the HTTP code 0.
No need for custom middleware?! In express:
//you probably have something like this already
app.use("/public", express.static('public'));
Then put your favicon in public and add the following line in your html's head:
<link rel="icon" href="/public/favicon.ico">
If you want to ensure only that class will match then use getClass() ==
. If you want to match subclasses then instanceof
is needed.
Also, instanceof will not match against a null but is safe to compare against a null. So you don't have to null check it.
if ( ! (obj instanceof MyClass) ) { return false; }
Below is a working code to add a fragment e.g 3 times to a vertical LinearLayout (xNumberLinear). You can change number 3 with any other number or take a number from a spinner!
for (int i = 0; i < 3; i++) {
LinearLayout linearDummy = new LinearLayout(getActivity());
linearDummy.setOrientation(LinearLayout.VERTICAL);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
Toast.makeText(getActivity(), "This function works on newer versions of android", Toast.LENGTH_LONG).show();
} else {
linearDummy.setId(View.generateViewId());
}
fragmentManager.beginTransaction().add(linearDummy.getId(), new SomeFragment(),"someTag1").commit();
xNumberLinear.addView(linearDummy);
}
Here is what I did to solve just by 2 ways:
make ID column as int
type
if you are using autogenerate in ID dont assing value in the setter of ID. If your mapping the some then sometimes autogenetated ID is not concedered. (I dont know why)
try using @GeneratedValue(strategy=GenerationType.SEQUENCE)
if possible
As of .NET 4.7
the preferred method of overriding GetHashCode()
is shown below. If targeting older .NET versions, include the System.ValueTuple nuget package.
// C# 7.0+
public override int GetHashCode() => (FooId, FooName).GetHashCode();
In terms of performance, this method will outperform most composite hash code implementations. The ValueTuple is a struct
so there won't be any garbage, and the underlying algorithm is as fast as it gets.
If you're using .NET 2.0, try XmlReader
and its subclasses XmlTextReader
, and XmlValidatingReader
. They provide a fast, lightweight (memory usage, etc.), forward-only way to parse an XML file.
If you need XPath
capabilities, try the XPathNavigator
. If you need the entire document in memory try XmlDocument
.
You can solve this issue be adding max-width
:
#element {
width: 100vw;
height: 100vw;
max-width: 100%;
}
When you using CSS to make the wrapper full width using the code width: 100vw;
then you will notice a horizontal scroll in the page, and that happened because the padding
and margin
of html
and body
tags added to the wrapper size, so the solution is to add max-width: 100%
const
guarantees that a program does not change an object’s value. However, const
does not guarantee which type of initialization the object undergoes.
Consider:
const int mx = numeric_limits<int>::max(); // OK: runtime initialization
The function max()
merely returns a literal value. However, because the initializer is a function call, mx
undergoes runtime initialization. Therefore, you cannot use it as a constant expression:
int arr[mx]; // error: “constant expression required”
constexpr
is a new C++11 keyword that rids you of the need to create macros and hardcoded literals. It also guarantees, under certain conditions, that objects undergo static initialization. It controls the evaluation time of an expression. By enforcing compile-time evaluation of its expression, constexpr
lets you define true constant expressions that are crucial for time-critical applications, system programming, templates, and generally speaking, in any code that relies on compile-time constants.
A constant-expression function is a function declared constexpr
. Its body must be non-virtual and consist of a single return statement only, apart from typedefs and static asserts. Its arguments and return value must have literal types. It can be used with non-constant-expression arguments, but when that is done the result is not a constant expression.
A constant-expression function is meant to replace macros and hardcoded literals without sacrificing performance or type safety.
constexpr int max() { return INT_MAX; } // OK
constexpr long long_max() { return 2147483647; } // OK
constexpr bool get_val()
{
bool res = false;
return res;
} // error: body is not just a return statement
constexpr int square(int x)
{ return x * x; } // OK: compile-time evaluation only if x is a constant expression
const int res = square(5); // OK: compile-time evaluation of square(5)
int y = getval();
int n = square(y); // OK: runtime evaluation of square(y)
A constant-expression object is an object declared constexpr
. It must be initialized with a constant expression or an rvalue constructed by a constant-expression constructor with constant-expression arguments.
A constant-expression object behaves as if it was declared const
, except that it requires initialization before use and its initializer must be a constant expression. Consequently, a constant-expression object can always be used as part of another constant expression.
struct S
{
constexpr int two(); // constant-expression function
private:
static constexpr int sz; // constant-expression object
};
constexpr int S::sz = 256;
enum DataPacket
{
Small = S::two(), // error: S::two() called before it was defined
Big = 1024
};
constexpr int S::two() { return sz*2; }
constexpr S s;
int arr[s.two()]; // OK: s.two() called after its definition
A constant-expression constructor is a constructor declared constexpr
. It can have a member initialization list but its body must be empty, apart from typedefs and static asserts. Its arguments must have literal types.
A constant-expression constructor allows the compiler to initialize the object at compile-time, provided that the constructor’s arguments are all constant expressions.
struct complex
{
// constant-expression constructor
constexpr complex(double r, double i) : re(r), im(i) { } // OK: empty body
// constant-expression functions
constexpr double real() { return re; }
constexpr double imag() { return im; }
private:
double re;
double im;
};
constexpr complex COMP(0.0, 1.0); // creates a literal complex
double x = 1.0;
constexpr complex cx1(x, 0); // error: x is not a constant expression
const complex cx2(x, 1); // OK: runtime initialization
constexpr double xx = COMP.real(); // OK: compile-time initialization
constexpr double imaglval = COMP.imag(); // OK: compile-time initialization
complex cx3(2, 4.6); // OK: runtime initialization
Tips from the book Effective Modern C++ by Scott Meyers about constexpr
:
constexpr
objects are const and are initialized with values known during compilation;constexpr
functions produce compile-time results when called with arguments whose values are known during compilation;constexpr
objects and functions may be used in a wider range of contexts than non-constexpr
objects and functions;constexpr
is part of an object’s or function’s interface.Source: Using constexpr to Improve Security, Performance and Encapsulation in C++.
It's usually the metacharacter .

So use ^.{1,35}$

You can use ^[\S\s]{1,35}$
without any modifiers, and this includes newlines as well.

If you are using fastexml jackson, you can use the following:
com.fasterxml.jackson.core.io.JsonStringEncoder.getInstance().quoteAsString(input)
If you are using codehaus jackson, you can use the following:
org.codehaus.jackson.io.JsonStringEncoder.getInstance().quoteAsString(input)
String formatting, using the new-style .format()
method (with the defaults .format() provides):
'{}{}'.format(s, i)
Or the older, but "still sticking around", %
-formatting:
'%s%d' %(s, i)
In both examples above there's no space between the two items concatenated. If space is needed, it can simply be added in the format strings.
These provide a lot of control and flexibility about how to concatenate items, the space between them etc. For details about format specifications see this.
Here's an example:
#Create a data frame
> d<- data.frame(a=1:3, b=2:4)
> d
a b
1 1 2
2 2 3
3 3 4
#currently, there are no levels in the `a` column, since it's numeric as you point out.
> levels(d$a)
NULL
#Convert that column to a factor
> d$a <- factor(d$a)
> d
a b
1 1 2
2 2 3
3 3 4
#Now it has levels.
> levels(d$a)
[1] "1" "2" "3"
You can also handle this when reading in your data. See the colClasses
and stringsAsFactors
parameters in e.g. readCSV()
.
Note that, computationally, factoring such columns won't help you much, and may actually slow down your program (albeit negligibly). Using a factor will require that all values are mapped to IDs behind the scenes, so any print of your data.frame requires a lookup on those levels -- an extra step which takes time.
Factors are great when storing strings which you don't want to store repeatedly, but would rather reference by their ID. Consider storing a more friendly name in such columns to fully benefit from factors.

V->T
where V=variable and T=terminal
RG may be Left Linear Grammar or Right Liner Grammar, but not Middle linear Grammar.
As we know all RG are Linear Grammar but only Left Linear or Right Linear Grammar are RG.
A regular grammar can be ambiguous.

You first mention this code:
throw new Error('sample')
and then in your first example you write:
throw new Error({'hehe':'haha'})
The first Error object would actually be useful, because it is expecting a string value, in this case 'sample'. The second would not because you are trying to pass an object in, and it is expecting a string, and would not display a helpful error.
The error object would have the "message" property, which would be 'sample'.

Also, there seems to be missing an (

You are now good to go! ReportViewer icon will be added to your toolbar, and you will also now find Report and ReportWizard templates added to your Common list of templates when you want to add a New Item... (Report) to your project
NB: When set up using Nuget package manager, the Report and ReportWizard templates are grouped under Reporting. Using my method described above however does not add the Reporting grouping in installed templates, but I dont think it is any trouble given that it enables you to quickly integrate rdlc without internet and without downloading what you already have from Nuget every time!

I just found the answer from a forum referred by one of my colleague. If you declare a variable outside a function, it's always global. No matter if you use var keyword or not. But, if you declare the variable inside a function, it has a big difference. Inside a function, if you declare the variable using var keyword, it will be local, but if you declare the variable without var keyword, it will be global. It can overwrite your previously declared variables. - See more at: http://forum.webdeveloperszone.com/question/what-is-the-difference-between-using-var-keyword-or-not-using-var-during-variable-declaration/#sthash.xNnLrwc3.dpuf

the path you are using is not correct you could just open the node_module and find the path of font-awesome. use could use js or svg font but i prefer the css style.
at first use this command to install font-awesome-free
npm install --save-dev @fortawesome/fontawesome-free
after that you can do this
@import "~@fortawesome/fontawesome-free/scss/fontawesome";
@import "~@fortawesome/fontawesome-free/scss/regular";
@import "~@fortawesome/fontawesome-free/scss/solid";
@import "~@fortawesome/fontawesome-free/scss/brands";
and I copy the font path like below this is optional
.copy('node_modules/@fortawesome/fontawesome-free/webfonts', 'public/fonts');
and finally just run the script
npm run dev
or npm run watch
in laravel

In case anyone is as dopey as me, double check the year of your date. I was converting a date from a text file in YYMMDD format so was creating a date with a year of 0020, not 2020. Obvious error but I spent more time looking at it but not seeing it than I should have!
I had the same problem and this worked for me:
If you don't want to drag in libraries, it's simple enough to do yourself using a Formatter, or related shortcut eg. given integer number of seconds s:
String.format("%d:%02d:%02d", s / 3600, (s % 3600) / 60, (s % 60));
