Here is the code to generate random alphanumeric code. First you have to declare a string of allowed characters what you want to include in random number.and also define max length of string
SecureRandom secureRandom = new SecureRandom();
String CHARACTERS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789";
StringBuilder generatedString= new StringBuilder();
for (int i = 0; i < MAXIMUM_LENGTH; i++) {
int randonSequence = secureRandom .nextInt(CHARACTERS.length());
generatedString.append(CHARACTERS.charAt(randonSequence));
}
Use toString() method to get String from StringBuilder
Another recursive approach:
# change directory to target folder:
cd /Volumes/path/to/folder
# find all things of type "f" (file),
# then pipe "|" each result as an argument (xargs -0)
# to the "xattr -c" command:
find . -type f -print0 | xargs -0 xattr -c
# Sometimes you may have to use a star * instead of the dot.
# The dot just means "here" (whereever your cd'd to
find * -type f -print0 | xargs -0 xattr -c
I've taken your code and adapted it with library react-form-with-constraints: https://codepen.io/tkrotoff/pen/LLraZp
const {
FormWithConstraints,
FieldFeedbacks,
FieldFeedback
} = ReactFormWithConstraints;
class Form extends React.Component {
handleChange = e => {
this.form.validateFields(e.target);
}
contactSubmit = e => {
e.preventDefault();
this.form.validateFields();
if (!this.form.isValid()) {
console.log('form is invalid: do not submit');
} else {
console.log('form is valid: submit');
}
}
render() {
return (
<FormWithConstraints
ref={form => this.form = form}
onSubmit={this.contactSubmit}
noValidate>
<div className="col-md-6">
<input name="name" size="30" placeholder="Name"

Here is how i solved it. i know if you have several physical interfaces this might not select the exact eth you want.
private string FetchIP()
{
//Get all IP registered
List<string> IPList = new List<string>();
IPHostEntry host;
host = Dns.GetHostEntry(Dns.GetHostName());
foreach (IPAddress ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
IPList.Add(ip.ToString());
}
}
//Find the first IP which is not only local
foreach (string a in IPList)
{
Ping p = new Ping();
string[] b = a.Split('.');
string ip2 = b[0] + "." + b[1] + "." + b[2] + ".1";
PingReply t = p.Send(ip2);
p.Dispose();
if (t.Status == IPStatus.Success && ip2 != a)
{
return a;
}
}
return null;
}
You can try RuneCountInString
from the utf8 package.
returns the number of runes in p
that, as illustrated in this script: the length of "World" might be 6 (when written in Chinese: "??"), but its rune count is 2:
package main
import "fmt"
import "unicode/utf8"
func main() {
fmt.Println("Hello, ??", len("??"), utf8.RuneCountInString("??"))
}
Phrozen adds in the comments:
Actually you can do len()
over runes by just type casting.
len([]rune("??"))
will print 2
. At leats in Go 1.3.
And with CL 108985 (May 2018, for Go 1.11), len([]rune(string))
is now optimized. (Fixes issue 24923)
The compiler detects len([]rune(string))
pattern automatically, and replaces it with for r := range s call.
Adds a new runtime function to count runes in a string. Modifies the compiler to detect the pattern
len([]rune(string))
and replaces it with the new rune counting runtime function.RuneCount/lenruneslice/ASCII 27.8ns ± 2% 14.5ns ± 3% -47.70% RuneCount/lenruneslice/Japanese 126ns ± 2% 60 ns ± 2% -52.03% RuneCount/lenruneslice/MixedLength 104ns ± 2% 50 ns ± 1% -51.71%
Stefan Steiger points to the blog post "Text normalization in Go"
What is a character?
As was mentioned in the strings blog post, characters can span multiple runes.
For example, an 'e
' and '?´?´' (acute "\u0301") can combine to form 'é' ("e\u0301
" in NFD). Together these two runes are one character.The definition of a character may vary depending on the application.
For normalization we will define it as:
- a sequence of runes that starts with a starter,
- a rune that does not modify or combine backwards with any other rune,
- followed by possibly empty sequence of non-starters, that is, runes that do (typically accents).
The normalization algorithm processes one character at at time.
Using that package and its Iter
type, the actual number of "character" would be:
package main
import "fmt"
import "golang.org/x/text/unicode/norm"
func main() {
var ia norm.Iter
ia.InitString(norm.NFKD, "école")
nc := 0
for !ia.Done() {
nc = nc + 1
ia.Next()
}
fmt.Printf("Number of chars: %d\n", nc)
}
Here, this uses the Unicode Normalization form NFKD "Compatibility Decomposition"
Oliver's answer points to UNICODE TEXT SEGMENTATION as the only way to reliably determining default boundaries between certain significant text elements: user-perceived characters, words, and sentences.
For that, you need an external library like rivo/uniseg, which does Unicode Text Segmentation.
That will actually count "grapheme cluster", where multiple code points may be combined into one user-perceived character.
package uniseg
import (
"fmt"
"github.com/rivo/uniseg"
)
func main() {
gr := uniseg.NewGraphemes("!")
for gr.Next() {
fmt.Printf("%x ", gr.Runes())
}
// Output: [1f44d 1f3fc] [21]
}
Two graphemes, even though there are three runes (Unicode code points).
You can see other examples in "How to manipulate strings in GO to reverse them?"
? alone is one grapheme, but, from unicode to code points converter, 4 runes:
The following adds elements to a list in a loop.
l<-c()
i=1
while(i<100) {
b<-i
l<-c(l,b)
i=i+1
}
If you are on a mysql server and if you don't mind loosing your tables, you can use a simple query to delete multiple tables at once:
SET foreign_key_checks = 0;
DROP TABLE IF EXISTS table_a,table_b,table_c,table_etc;
SET foreign_key_checks = 1;
In this way it doesn't matter in what order you use the table in you query.
If anybody is going to say something about the fact that this is not a good solution if you have a database with many tables: I agree!
You should be able to see the schema by running
.schema <table>
I see this nice tutorial on how to get the like count from facebook using PHP.
public static function get_the_fb_like( $url = '' ){
$pageURL = 'http://nextopics.com';
$url = ($url == '' ) ? $pageURL : $url; // setting a value in $url variable
$params = 'select comment_count, share_count, like_count from link_stat where url = "'.$url.'"';
$component = urlencode( $params );
$url = 'http://graph.facebook.com/fql?q='.$component;
$fbLIkeAndSahre = json_decode( $this->file_get_content_curl( $url ) );
$getFbStatus = $fbLIkeAndSahre->data['0'];
return $getFbStatus->like_count;
}
here is a sample code.. I don't know how to paste the code with correct format in here, so just kindly visit this link for better view of the code.
I created a small application which had similar functionality

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer);

R.string.close
)
{

{
super.onDrawerClosed(view);
invalidateOptionsMenu();
syncState();
}
public void onDrawerOpened(View drawerView)
{
super.onDrawerOpened(drawerView);
invalidateOptionsMenu();
syncState();
}
};
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//Set the custom toolbar
if (toolbar != null){
setSupportActionBar(toolbar);
}
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
actionBarDrawerToggle.syncState();

You can use the NotMapped
attribute data annotation to instruct Code-First to exclude a particular property
public class Customer
{
public int CustomerID { set; get; }
public string FirstName { set; get; }
public string LastName{ set; get; }
[NotMapped]
public int Age { set; get; }
}
[NotMapped]
attribute is included in the System.ComponentModel.DataAnnotations
namespace.
You can alternatively do this with Fluent API
overriding OnModelCreating
function in your DBContext
class:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
base.OnModelCreating(modelBuilder);
}
http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx
The version I checked is EF 4.3
, which is the latest stable version available when you use NuGet.
Edit : SEP 2017
Data annotation
If you are using asp.net core (2.0 at the time of this writing), The [NotMapped]
attribute can be used on the property level.
public class Customer
{
public int Id { set; get; }
public string FirstName { set; get; }
public string LastName { set; get; }
[NotMapped]
public int FullName { set; get; }
}
Fluent API
public class SchoolContext : DbContext
{
public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
base.OnModelCreating(modelBuilder);
}
public DbSet<Customer> Customers { get; set; }
}
In jQuery 1.2 and newer you no longer have to position the element absolutely; you can use normal relative positioning and use += or -= to add to or subtract from properties, e.g.
$("#startAnimation").click(function(){
$(".toBeAnimated").animate({
marginLeft: "+=250px",
}, 1000 );
});
And to echo the guy who answered first's advice: Javascript is not performant. Don't overuse animations, or expect things than run nice and fast on your high performance PC on Chrome to look good on a bog-standard PC running IE. Test it, and make sure it degrades well!
Jon's answer didn't work for me as I got a compiler error CS0453 C# The type must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method
This worked for me though:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<SomeObject>().HasOptional(m => m.somefield);
base.OnModelCreating(modelBuilder);
}
Based on dominic Rodger's solution, here is what I use (it uses wc if available, otherwise fallbacks to dominic Rodger's solution).
class FileTool
{
public static function getNbLines($file)
{
$linecount = 0;
$m = exec('which wc');
if ('' !== $m) {
$cmd = 'wc -l < "' . str_replace('"', '\\"', $file) . '"';
$n = exec($cmd);
return (int)$n + 1;
}
$handle = fopen($file, "r");
while (!feof($handle)) {
$line = fgets($handle);
$linecount++;
}
fclose($handle);
return $linecount;
}
}
My problem was to access the logged in User as an object in the cshtml file. Considering you wanted the user in ViewData, this approach might be helpful:
In the cshtml file
@using Microsoft.AspNetCore.Identity
@inject UserManager<ApplicationUser> UserManager
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>
@UserManager.FindByNameAsync(UserManager.GetUserName(User)).Result.Email
</title>
</head>
<body>
</body>
</html>
If you need to open the DevTools press ctrl-shift-i.
If the DevTools window is already opened you can use the ctrl-shift-d shortcut; it switches the window into a detached mode.
For example in my case the electron application window (Chrome) is really small.
It's not possible to use any other suggestions except the ctrl-shift-d shortcut
If upgarde angular to 8+ you must change in angular.json

"output": "/assets/"

What levi said about passing it into the constructor is correct, but you could also use an object.
I think what Veverke is trying to say is that you could easily use the delete
keyword on an object to achieve the same effect.
I think you're confused by the terminology; properties are components of the object that you can use as named indices (if you want to think of it that way).
Try something like this:
var obj = {
"bob": "dole",
"mr.": "peabody",
"darkwing": "duck"
};
Then, you could just do this:
delete obj["bob"];
The structure of the object would then be this:
{
"mr.": "peabody",
"darkwing": "duck"
}
Which has the same effect.
#include<stdio.h>
int main()
{
int a,b,i,c,j;
printf("\n Enter the two no. in between you want to check:");
scanf("%d%d",&a,&c);
printf("%d-%d\n",a,c);
for(j=a;j<=c;j++)
{
b=0;
for(i=1;i<=c;i++)
{
if(j%i==0)
{
b++;
}
}
if(b==2)
{
printf("\nPrime number:%d\n",j);
}
else
{
printf("\n\tNot prime:%d\n",j);
}
}
}

net stop <service name>
net start <service name>

Since you mentioned stdout.txt I google'd it to see what exactly would create a stdout.txt; normally, even with a Windows app, console output goes to the allocated console, or nowhere if one is not allocated.
So, assuming you are using SDL (which is the only thing that brought up stdout.txt), you should follow the advice here. Either freopen stdout and stderr with "CON", or do the other linker/compile workarounds there.
In case the link gets broken again, here is exactly what was referenced from libSDL:
How do I avoid creating stdout.txt and stderr.txt?

Because lock is expensive, when you are using synchronized block you lock only if _instance == null
, and after _instance
finally initialized you'll never lock. But when you synchronize on method you lock unconditionally, even after the _instance
is initialized. This is the idea behind double-checked locking optimization pattern http://en.wikipedia.org/wiki/Double-checked_locking.
Your constructor is expecting one parameter (data). You're not passing it in the call. I guess you wanted to initialise a field in the object. That would look like this:
class DHT:
def __init__(self):
self.data = {}
self.data['one'] = '1'
self.data['two'] = '2'
self.data['three'] = '3'
def showData(self):
print(self.data)
if __name__ == '__main__':
DHT().showData()
Or even just:
class DHT:
def __init__(self):
self.data = {'one': '1', 'two': '2', 'three': '3'}
def showData(self):
print(self.data)
Just use the table name:
SELECT myTable.*, otherTable.foo, otherTable.bar...
That would select all columns from myTable
and columns foo
and bar
from otherTable
.
Singleton's are instantiated, it's just there's only one instance ever instantiated, hence the single in Singleton.
A static class can't be instantiated by anything other than itself.

It's possible using jQuery it depends on your site load time you can adjust your timeout. It can be your custom image or you can use youtube image maxres1.jpg, maxres2.jpg or maxres3.jpg
var newImage = 'http://i.ytimg.com/vi/[Video_ID]/maxres1.jpg';
window.setTimeout(function() {
jQuery('div > div.video-container-thumb > div > a > img').attr('src',newImage );
}, 300);
The following demonstrates an alternative approach for returning a key pair object using the form of (a, b)
. The first example uses the string 'key'
as the property name, and 'val'
as the value.
Example #1:
(function(o,a,b){return o[a]=b,o})({},'key','val');
Example: #2:
var obj = { foo: 'bar' };
(function(o,a,b){return o[a]=b,o})(obj,'key','val');
As shown in the second example, this can modify existing objects, too (if property is already defined in the object, value will be overwritten).
Result #1:
{ key: 'val' }
Result #2:
{ foo: 'bar', key: 'val' }
The following code works to prevent column breaks inside elements:
-webkit-column-break-inside: avoid;
-moz-column-break-inside: avoid;
-o-column-break-inside: avoid;
-ms-column-break-inside: avoid;
column-break-inside: avoid;
Clickatell is a popular SMS gateway. It works in 200+ countries.
Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.
The HTTP/S method is as simple as this:
http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here
The SMTP method consists of sending a plain-text e-mail to: [email protected]
, with the following body:
user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home
You can also test the gateway (incoming and outgoing) for free from your browser

Python does have a multiline string/comment syntax in the sense that unless used as docstrings, multiline strings generate no bytecode -- just like #-prepended comments. In effect, it acts exactly like a comment.
On the other hand, if you say this behavior must be documented in the official docs to be a true comment syntax, then yes, you would be right to say it is not guaranteed as part of the language specification.
In any case your editor should also be able to easily comment-out a selected region (by placing a # in front of each line individually). If not, switch to an editor that does.
Programming in Python without certain text editing features can be a painful experience. Finding the right editor (and knowing how to use it) can make a big difference in how the Python programming experience is perceived.
Not only should the editor be able to comment-out selected regions, it should also be able to shift blocks of code to the left and right easily, and should automatically place the cursor at the current indentation level when you press Enter. Code folding can also be useful.

.The best solution, you can manage the multiple node versions using nvm installer. then, install the required node's version using below command
nvm install version
Use below command as a working node with mentioned version alone
nvm use version
now, you can use any version node without uninstalling previous installed node.
You have the most efficient representation already - it's the bare minimum that needs to be checked unless you know for sure that x1 < x2 etc, then use the solutions others have provided.
You should probably note that some compilers will actually optimise this for you - by returning as soon as any of those 4 expressions return true. If one returns true, so will the end result - so the other checks can just be skipped.
In VB.Net. Do NOT use "IsNot Nothing" when you can use ".HasValue". I just solved an "Operation could destabilize the runtime" Medium trust error by replacing "IsNot Nothing" with ".HasValue" In one spot. I don't really understand why, but something is happening differently in the compiler. I would assume that "!= null" in C# may have the same issue.
If nothing worked use git rm filename to delete file from disk and add it back.
I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.
To answer the question in the header: To install make in ubuntu you have to install build-essentials
sudo apt-get install build-essential
ElementFormDefault has nothing to do with namespace of the types in the schema, it's about the namespaces of the elements in XML documents which comply with the schema.
Here's the relevent section of the spec:
Element Declaration Schema Component Property {target namespace} Representation If form is present and its ·actual value· is qualified, or if form is absent and the ·actual value· of elementFormDefault on the <schema> ancestor is qualified, then the ·actual value· of the targetNamespace [attribute] of the parent <schema> element information item, or ·absent· if there is none, otherwise ·absent·.
What that means is that the targetNamespace you've declared at the top of the schema only applies to elements in the schema compliant XML document if either elementFormDefault is "qualified" or the element is declared explicitly in the schema as having form="qualified".
For example: If elementFormDefault is unqualified -
<element name="name" type="string" form="qualified"></element>
<element name="page" type="target:TypePage"></element>
will expect "name" elements to be in the targetNamespace and "page" elements to be in the null namespace.
To save you having to put form="qualified" on every element declaration, stating elementFormDefault="qualified" means that the targetNamespace applies to each element unless overridden by putting form="unqualified" on the element declaration.

I have tried 2 options which both work on my company's NTLM authenticated proxy.
Option 1 is to use --proxy http://user:pass@proxyAddress:proxyPort
If you are still having trouble I would suggest installing a proxy authentication service (I use CNTLM) and pointing pip at it ie something like --proxy http://localhost:3128
I have been getting similar error, and just want to share with you. maybe it will help someone.
If you want to use EntityManagerFactory
to get an EntityManager
, make sure that you will use:
<persistence-unit name="name" transaction-type="RESOURCE_LOCAL">
and not:
<persistence-unit name="name" transaction-type="JPA">
in persistance.xml
clean and rebuild project, it should help.
This maybe what you're looking for:
awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'
That is, with '\''
you close the opening '
, then print a literal '
by escaping it and finally open the '
again.
For people (like me) who really want PathLocationStrategy
(i.e. html5Mode) instead of HashLocationStrategy
, see How to: Configure your server to work with html5Mode from a third-party wiki:
When you have html5Mode enabled, the
#
character will no longer be used in your URLs. The#
symbol is useful because it requires no server side configuration. Without#
, the URL looks much nicer, but it also requires server side rewrites.
Here I only copy three examples from the wiki, in case the Wiki get lost. Other examples can be found by searching keyword "URL rewrite" (e.g. this answer for Firebase).

If you have an async method called " RefreshList " then, you can call that async method from a non-async method like below.
Task.Run(async () => { await RefreshList(); });
I struggled with this as well but heres the solution. If you add "
before and at the end of the csv string you are trying to display, it will consolidate them into 1 cell while honoring new line.
csvString += "\""+"Date Generated: \n" ;
csvString += "Doctor: " + "\n"+"\"" + "\n";
Likewise,
$myNewObj->setNewVar = 'newVal';
yields a stdClass object - auto casted
I found this out today by misspelling:
$GLOBASLS['myObj']->myPropertyObj->myProperty = 'myVal';
Cool!
I don't know why do you need this onmousedown
event here, but what you have to do is put your function above actual usage. Look at the snipplet below:
<script type="text/javascript">_x000D_
function jsFunction(value)_x000D_
{_x000D_
alert(value);_x000D_
}_x000D_
</script>_x000D_
_x000D_
<select id ="ddl" name="ddl" onmousedown="this.value='';" onchange="jsFunction(this.value);">_x000D_
<option value='1'>One</option>_x000D_
<option value='2'>Two</option>_x000D_
<option value='3'>Three</option>_x000D_
</select>

It says "POST not supported", so the request is not calling your servlet. If I were you, I will issue a GET (e.g. access using a browser) to the exact URL you are issuing your POST request, and see what you get. I bet you'll see something unexpected.
Regex pattern for matching only alphabets and white spaces:
String regexUserName = "^[A-Za-z\\s]+$";
Thou shalt always encode URLs.
Here is how Ruby encodes your URL:
irb(main):008:0> CGI.escape "a.com/a+b"
=> "a.com%2Fa%2Bb"
Make sure return type of you method is same what you want to return. Eg: `
public int get(int[] r)
{
return r[0];
}
`
Note : return type is int, not int[], so it is able to return int.
In general, prototype can be
public Type get(Type[] array, int index)
{
return array[index];
}
Visibility:
While your angularjs is bootstrapping, the user might see your placed brackets in the html. This can be handled with ng-cloak
. But for me this is a workaround, that I don't need to use, if I use ng-bind
.
Performance:
The {{}}
is much slower.
This ng-bind
is a directive and will place a watcher on the passed variable.
So the ng-bind
will only apply, when the passed value does actually change.
The brackets on the other hand will be dirty checked and refreshed in every $digest
, even if it's not necessary.
I am currently building a big single page app (~500 bindings per view). Changing from {{}} to strict ng-bind
did save us about 20% in every scope.$digest
.
Suggestion:
If you use a translation module such as angular-translate, always prefer directives before brackets annotation.
{{'WELCOME'|translate}}
=> <span ng-translate="WELCOME"></span>
If you need a filter function, better go for a directive, that actually just uses your custom filter. Documentation for $filter service
UPDATE 28.11.2014 (but maybe off the topic):
In Angular 1.3x the bindonce
functionality was introduced. Therefore you can bind the value of an expression/attribute once (will be bound when != 'undefined').
This is useful when you don't expect your binding to change.
Usage:
Place ::
before your binding:
<ul>
<li ng-repeat="item in ::items">{{item}}</li>
</ul>
<a-directive name="::item">
<span data-ng-bind="::value"></span>
Example:
ng-repeat
to output some data in the table, with multiple bindings per row.
Translation-bindings, filter outputs, which get executed in every scope digest.
getFragmentManager()
just try this.it worked for my case
A slightly more complicated, but far more flexible, alternative is to create a class that represents a configuration section. In your app.config
/ web.config
file, you can have this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<!-- This section must be the first section within the <configuration> node -->
<configSections>
<section name="DirectoryInfo" type="MyProjectNamespace.DirectoryInfoConfigSection, MyProjectAssemblyName" />
</configSections>
<DirectoryInfo>
<Directory MyBaseDir="C:\MyBase" Dir1="Dir1" Dir2="Dir2" />
</DirectoryInfo>
</configuration>
Then, in your .NET code (I'll use C# in my example), you can create two classes like this:
using System;
using System.Configuration;
namespace MyProjectNamespace {
public class DirectoryInfoConfigSection : ConfigurationSection {
[ConfigurationProperty("Directory")]
public DirectoryConfigElement Directory {
get {
return (DirectoryConfigElement)base["Directory"];
}
}
public class DirectoryConfigElement : ConfigurationElement {
[ConfigurationProperty("MyBaseDir")]
public String BaseDirectory {
get {
return (String)base["MyBaseDir"];
}
}
[ConfigurationProperty("Dir1")]
public String Directory1 {
get {
return (String)base["Dir1"];
}
}
[ConfigurationProperty("Dir2")]
public String Directory2 {
get {
return (String)base["Dir2"];
}
}
// You can make custom properties to combine your directory names.
public String Directory1Resolved {
get {
return System.IO.Path.Combine(BaseDirectory, Directory1);
}
}
}
}
Finally, in your program code, you can access your app.config
variables, using your new classes, in this manner:
DirectoryInfoConfigSection config =
(DirectoryInfoConfigSection)ConfigurationManager.GetSection("DirectoryInfo");
String dir1Path = config.Directory.Directory1Resolved; // This value will equal "C:\MyBase\Dir1"
Have a same problem. My solution is after you handle with parsing arguments using argparse or other way, remove arguments from sys.argv
sys.argv = sys.argv[:1]
If you need you can filter unittest arguments from main.parseArgs()
Alternatively you could update brew
by installing it again. (Think I did this as El Capitan changed something)
Note: this is a heavy handed approach that will remove all applications installed via brew!
Try to install brew a fresh and it will tell how to uninstall.
At original time of writing to uninstall:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Edit: As of 2020 to uninstall:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
I got the error below when I run 'ant deploy'
Cannot run program "C:\java\jdk1.8.0_45\bin\java.exe": CreateProcess error=206, The filename or extension is too long
Fixed it by run 'ant clean' before it.
I tried updating all of my SDKs by just going into the Project Structure > Platform Settings > SDKs and changing the Java SDK, but that didn't work, so I had to recreate the configurations from scratch.
Here's how to create your SDKs with the latest Java:
Read From Config:
You'll need to add a reference to the configuration:
Get Value with using following code:
string value = Properties.Settings.Default.keyname;
Save to the configuration:
Properties.Settings.Default.keyName = value;
Properties.Settings.Default.Save();
Target the element you wish to change and use !important
to overwrite any existing styles that are assigned to that element. Be sure not to use the !important
declaration when it is not absolutely necessary.
div.navbar div.navbar-inner ul.nav a:hover {
color: #fff !important;
}
I'm just starting some string manipulations and found this question. I was probably trying to do something like the OP, "usual me". The previous answers did not clear up my confusion, but after thinking a little about it I finally "got it".
As long as a
, b
, c
, d
, and e
have the same value, they reference to the same place. Memory is saved. As soon as the variable start to have different values, they get start to have different references. My learning experience came from this code:
import copy
a = 'hello'
b = str(a)
c = a[:]
d = a + ''
e = copy.copy(a)
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e
e = a + 'something'
a = 'goodbye'
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e
The printed output is:
[4538504992, 4538504992, 4538504992, 4538504992, 4538504992]
hello hello hello hello hello
[6113502048, 4538504992, 4538504992, 4538504992, 5570935808]
goodbye hello hello hello hello something
A compilation in C++ is done in 2 major phases:
The first is the compilation of "source" text files into binary "object" files: The CPP file is the compiled file and is compiled without any knowledge about the other CPP files (or even libraries), unless fed to it through raw declaration or header inclusion. The CPP file is usually compiled into a .OBJ or a .O "object" file.
The second is the linking together of all the "object" files, and thus, the creation of the final binary file (either a library or an executable).
Where does the HPP fit in all this process?
The compilation of each CPP file is independent from all other CPP files, which means that if A.CPP needs a symbol defined in B.CPP, like:
// A.CPP
void doSomething()
{
doSomethingElse(); // Defined in B.CPP
}
// B.CPP
void doSomethingElse()
{
// Etc.
}
It won't compile because A.CPP has no way to know "doSomethingElse" exists... Unless there is a declaration in A.CPP, like:
// A.CPP
void doSomethingElse() ; // From B.CPP
void doSomething()
{
doSomethingElse() ; // Defined in B.CPP
}
Then, if you have C.CPP which uses the same symbol, you then copy/paste the declaration...
Yes, there is a problem. Copy/pastes are dangerous, and difficult to maintain. Which means that it would be cool if we had some way to NOT copy/paste, and still declare the symbol... How can we do it? By the include of some text file, which is commonly suffixed by .h, .hxx, .h++ or, my preferred for C++ files, .hpp:
// B.HPP (here, we decided to declare every symbol defined in B.CPP)
void doSomethingElse() ;
// A.CPP
#include "B.HPP"
void doSomething()
{
doSomethingElse() ; // Defined in B.CPP
}
// B.CPP
#include "B.HPP"
void doSomethingElse()
{
// Etc.
}
// C.CPP
#include "B.HPP"
void doSomethingAgain()
{
doSomethingElse() ; // Defined in B.CPP
}
include
work?Including a file will, in essence, parse and then copy-paste its content in the CPP file.
For example, in the following code, with the A.HPP header:
// A.HPP
void someFunction();
void someOtherFunction();
... the source B.CPP:
// B.CPP
#include "A.HPP"
void doSomething()
{
// Etc.
}
... will become after inclusion:
// B.CPP
void someFunction();
void someOtherFunction();
void doSomething()
{
// Etc.
}
In the current case, this is not needed, and B.HPP has the doSomethingElse
function declaration, and B.CPP has the doSomethingElse
function definition (which is, by itself a declaration). But in a more general case, where B.HPP is used for declarations (and inline code), there could be no corresponding definition (for example, enums, plain structs, etc.), so the include could be needed if B.CPP uses those declaration from B.HPP. All in all, it is "good taste" for a source to include by default its header.
The header file is thus necessary, because the C++ compiler is unable to search for symbol declarations alone, and thus, you must help it by including those declarations.
One last word: You should put header guards around the content of your HPP files, to be sure multiple inclusions won't break anything, but all in all, I believe the main reason for existence of HPP files is explained above.
#ifndef B_HPP_
#define B_HPP_
// The declarations in the B.hpp file
#endif // B_HPP_
or even simpler (although not standard)
#pragma once
// The declarations in the B.hpp file
For the most part, the number of bytes and range of values is determined by the CPU's architecture not by C++. However, C++ sets minimum requirements, which litb explained properly and Martin York only made a few mistakes with.
The reason why you can't use int and long interchangeably is because they aren't always the same length. C was invented on a PDP-11 where a byte had 8 bits, int was two bytes and could be handled directly by hardware instructions. Since C programmers often needed four-byte arithmetic, long was invented and it was four bytes, handled by library functions. Other machines had different specifications. The C standard imposed some minimum requirements.
To add to rcs' answer, if you want to use position_dodge() with geom_bar() when x is a POSIX.ct date, you must multiply the width by 86400, e.g.,
ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) +
geom_bar(position = "dodge", stat = 'identity') +
geom_text(aes(label=Number), position=position_dodge(width=0.9*86400), vjust=-0.25)

My team moved away from Bower and migrated to npm because:
For more details, see "Why my team uses npm instead of bower".
In case you had to deal with a lot of subfolders contatining subfolders and other recursive stuff. Small improvment of @Mike L'Angelo:
$mypath = "path_to_folder"
$myacl = Get-Acl $mypath
$myaclentry = "username","FullControl","Allow"
$myaccessrule = New-Object System.Security.AccessControl.FileSystemAccessRule($myaclentry)
$myacl.SetAccessRule($myaccessrule)
Get-ChildItem -Path "$mypath" -Recurse -Force | Set-Acl -AclObject $myacl -Verbose
Verbosity is optional in the last line
This is a complete cheat but I think that it adds value to this question because it's basically a canned library function that you can use out-of-the box.
If your code has access to lodash
or a lodash compatible library like underscore
then you can use the _.sortBy
method. The snippet below is copied directly from the lodash documentation.
The commented results in the examples looks like they return arrays of arrays but that's just showing the order and not the actual results which are an array of objects.
var users = [
{ 'user': 'fred', 'age': 48 },
{ 'user': 'barney', 'age': 36 },
{ 'user': 'fred', 'age': 40 },
{ 'user': 'barney', 'age': 34 }
];
_.sortBy(users, [function(o) { return o.user; }]);
// => objects for [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 40]]
_.sortBy(users, ['user', 'age']);
// => objects for [['barney', 34], ['barney', 36], ['fred', 40], ['fred', 48]]
Try:
@item.Date.ToString("dd MMM yyyy")
or you could use the [DisplayFormat]
attribute on your view model:
[DisplayFormat(DataFormatString = "{0:dd MMM yyyy}")]
public DateTime Date { get; set }
and in your view simply:
@Html.DisplayFor(x => x.Date)
Not with CSS you can't. You need to use JS. A quick example copying the img to the background:
var $el = document.getElementById( 'rightflower' )
, $img = $el.getElementsByTagName( 'img' )[0]
, src = $img.src
$el.innerHTML = "";
$el.style.background = "url( " + src + " ) repeat-y;"
Or you can actually repeat the image, but how many times?
var $el = document.getElementById( 'rightflower' )
, str = ""
, imgHTML = $el.innerHTML
, i, i2;
for( i=0,i2=10; i<i2; i++ ){
str += imgHTML;
}
$el.innerHTML = str;
You're running the code before the DOM is loaded.
Try this:
Live example:
$(function() { // Makes sure the code contained doesn't run until
// all the DOM elements have loaded
$('#colorselector').change(function(){
$('.colors').hide();
$('#' + $(this).val()).show();
});
});
The Kotlin
way by using builtin Extension function on File
Write: yourFile.writeText(textFromEditText)
Read: yourFile.readText()
You should try this one:
Console.WriteLine("{0}.{1}.{2}", mon, da, yet);
See http://www.dotnetperls.com/console-writeline for more details.
You also can use in this form:
<a href="@Url.Action("Information", "Admin", null)"> Admin</a>
I was getting this too, had me baffled for a while, even with the module and types already installed and reloading my IDE several times.
What fixed it in my case was terminating terminal processes, removing node_modules
, clearing the node package manager cache and doing a fresh install
then re-loading the editor.
I just learned this trick from a friend. Put your code inside these 2 statements and it will be commented out.
#if false
#endif
I had to solve the same issue and this is what I used as solution.
To use this solution the source and destination table must be identical, and the must have an id unique and autoincrement in first table (so that the same id is never reused).
Lets say table1 and table2 have this structure
|id|field1|field2
You can make those two query :
INSERT INTO table2 SELECT * FROM table1 WHERE
DELETE FROM table1 WHERE table1.id in (SELECT table2.id FROM table2)
Following is the util function to get current timestamp in milliseconds:
#include <sys/time.h>
long long current_timestamp() {
struct timeval te;
gettimeofday(&te, NULL); // get current time
long long milliseconds = te.tv_sec*1000LL + te.tv_usec/1000; // calculate milliseconds
// printf("milliseconds: %lld\n", milliseconds);
return milliseconds;
}
About timezone:
gettimeofday() support to specify timezone, I use NULL, which ignore the timezone, but you can specify a timezone, if need.
@Update - timezone
Since the long
representation of time is not relevant to or effected by timezone itself, so setting tz
param of gettimeofday() is not necessary, since it won't make any difference.
And, according to man page of gettimeofday()
, the use of the timezone
structure is obsolete, thus the tz
argument should normally be specified as NULL, for details please check the man page.
This method orderBy
does not change the input array,
you have to assign the result to your array :
var chars = this.state.characters;
chars = _.orderBy(chars, ['name'],['asc']); // Use Lodash to sort array by 'name'
this.setState({characters: chars})
Try RGBA, e.g.
div { background-color: rgba(255, 255, 255, 0.5); }
As always, this won't work in every single browser ever written.

This code works fine:

def readFile(filename):
filehandle = open(filename)
print filehandle.read()
filehandle.close()
fileDir = os.path.dirname(os.path.realpath('__file__'))
print fileDir
#For accessing the file in the same folder
filename = "same.txt"
readFile(filename)
#For accessing the file in a folder contained in the current folder
filename = os.path.join(fileDir, 'Folder1.1/same.txt')
readFile(filename)
#For accessing the file in the parent folder of the current folder
filename = os.path.join(fileDir, '../same.txt')
readFile(filename)
#For accessing the file inside a sibling folder.
filename = os.path.join(fileDir, '../Folder2/same.txt')
filename = os.path.abspath(os.path.realpath(filename))
print filename
readFile(filename)

You can do this without using refs. This approach is preferred, since refs can lead to fragile code. The React docs advise finding other solutions where possible:
If you have not programmed several apps with React, your first inclination is usually going to be to try to use refs to "make things happen" in your app. If this is the case, take a moment and think more critically about where state should be owned in the component hierarchy. Often, it becomes clear that the proper place to "own" that state is at a higher level in the hierarchy. Placing the state there often eliminates any desire to use refs to "make things happen" – instead, the data flow will usually accomplish your goal.
Instead, we'll use a state variable to focus the second input field.
Add a state variable that we'll pass as a prop to the DescriptionInput
:
initialState() {
return {
focusDescriptionInput: false,
};
}
Define a handler method that will set this state variable to true:
handleTitleInputSubmit() {
this.setState(focusDescriptionInput: true);
}
Upon submitting / hitting enter / next on the TitleInput
, we'll call handleTitleInputSubmit
. This will set focusDescriptionInput
to true.
<TextInput
style = {styles.titleInput}
returnKeyType = {"next"}
autoFocus = {true}
placeholder = "Title"
onSubmitEditing={this.handleTitleInputSubmit}
/>
DescriptionInput
's focus
prop is set to our focusDescriptionInput
state variable. So, when focusDescriptionInput
changes (in step 3), DescriptionInput
will re-render with focus={true}
.
<TextInput
style = {styles.descriptionInput}
multiline = {true}
maxLength = {200}
placeholder = "Description"
focus={this.state.focusDescriptionInput}
/>
This is a nice way to avoid using refs, since refs can lead to more fragile code :)
EDIT: h/t to @LaneRettig for pointing out that you'll need to wrap the React Native TextInput with some added props & methods to get it to respond to focus
:
// Props:
static propTypes = {
focus: PropTypes.bool,
}
static defaultProps = {
focus: false,
}
// Methods:
focus() {
this._component.focus();
}
componentWillReceiveProps(nextProps) {
const {focus} = nextProps;
focus && this.focus();
}
i believe that DI is a way of configurings or instantianting a bean. The DI can be done in many ways like constructor, setter-getter etc.
Factory pattern is just another way of instantiating beans. this pattern will be used mainly when you have to create objects using factory design pattern,because while using this pattern you dont configure the properties of a bean, only instantiate the object.
Check this link :Dependency Injection
ALTER TABLE `{$installer->getTable('sales/quote_payment')}`
ADD `custom_field_one` VARCHAR( 255 ) NOT NULL,
ADD `custom_field_two` VARCHAR( 255 ) NOT NULL;
Add backtick i.e. " ` " properly. Write your getTable name and column name between backtick.
Shouldn't that be:
<xsl:value-of select="/root/Image/img/@src"/>
? It looks like you are trying to copy the entire Image/img node to the attribute @src
listView.Items.Clear()
listView.Refresh()
/e Updating due to lack of explanation. Often times, Clear() isn't suffice in the event of immediate events / methods following. It's best to update the view with Refresh() following a Clear() for an instant reflection of the listView clearing. This, anyhow had solved my related issues.

The difference is not just for Chrome but for most of the web browsers.
F5
refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.
Shift + F5
forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.
Shift + F5
guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5
.
You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?
The underlying problem here is the 1st level cache of JPA. From the JPA spec Version 2.2 section 3.1. emphasise is mine:
An EntityManager instance is associated with a persistence context. A persistence context is a set of entity instances in which for any persistent entity identity there is a unique entity instance.
This is important because JPA tracks changes to that entity in order to flush them to the database. As a side effect it also means within a single persistence context an entity gets only loaded once. This why reloading the changed entity doesn't have any effect.
You have a couple of options how to handle this:
Evict the entity from the EntityManager
.
This may be done by calling EntityManager.detach
, annotating the updating method with @Modifying(clearAutomatically = true)
which evicts all entities.
Make sure changes to these entities get flushed first or you might end up loosing changes.
Use a different persistence context to load the entity.
The easiest way to do this is to do it in a separate transaction.
With Spring this can be done by having separate methods annotated with @Transactional
on beans called from a bean not annotated with @Transactional
.
Another way is to use a TransactionTemplate
which works especially nicely in tests where it makes transaction boundaries very visible.
The function name does not reflect the semantic of the function. In fact you do not append a character. You create a new character array that contains the original array plus the given character. So if you indeed need a function that appends a character to a character array I would write it the following way
bool AppendCharToCharArray( char *array, size_t n, char c )
{
size_t sz = std::strlen( array );
if ( sz + 1 < n )
{
array[sz] = c;
array[sz + 1] = '\0';
}
return ( sz + 1 < n );
}
If you need a function that will contain a copy of the original array plus the given character then it could look the following way
char * CharArrayPlusChar( const char *array, char c )
{
size_t sz = std::strlen( array );
char *s = new char[sz + 2];
std::strcpy( s, array );
s[sz] = c;
s[sz + 1] = '\0';
return ( s );
}
An old question, with a lot of answers, here's the steps I've recently followed reading the answers above, but in my case the problem was due to cifs resource sharing. This case is not reported previously, so hope it helps someone.
Try to force the lock mode on the connection opening with
final SQLiteConfig config = new SQLiteConfig();
config.setReadOnly(false);
config.setLockingMode(LockingMode.NORMAL);
connection = DriverManager.getConnection(url, config.toProperties());
If your using your SQLite db file over a NFS shared folder, check this point of the SQLite faq, and review your mounting configuration options to make sure your avoiding locks, as described here:
//myserver /mymount cifs username=*****,password=*****,iocharset=utf8,sec=ntlm,file,nolock,file_mode=0700,dir_mode=0700,uid=0500,gid=0500 0 0

Turning Hardware Acceleration OFF seems to be the setting that affects popups & dialogs.
Chrome was continually hiding Dialog Windows when I needed to respond Yes or No to things, also when I needed to Rename folders in my bookmarks panel. After weeks of doing this. I disabled all the Chrome helpers in Settings, Also In windows 10 I switched Window Snapping off. It has done something to put the popups and dialogs back in the Viewport.
When this bug is happening, I was able to shut a tab by first pressing Enter before clicking the tab close X button. The browser had an alert box, hidden which needed a response from the user.
Switching Hardware Accleration Off and back On, Killing the Chrome process and switching all the other Helpers Off and back has fixed it for me... It must be in chrome itself because Ive just gone into a Chrome window in the Mac and it has now stopped the problem, without any intervention. Im guessing flicking the chrome settings on/off/on has caused it to reposition the dialogs. I cant get the browser to repeat the fault now...
I wondered if it would be possible to avoid some of the disadvantages of using global variables (see e.g. http://wiki.c2.com/?GlobalVariablesAreBad) by using a class namespace rather than a global/module namespace to pass values of variables. The following code indicates that the two methods are essentially identical. There is a slight advantage in using class namespaces as explained below.
The following code fragments also show that attributes or variables may be dynamically created and deleted in both global/module namespaces and class namespaces.
wall.py
# Note no definition of global variables
class router:
""" Empty class """
I call this module 'wall' since it is used to bounce variables off of. It will act as a space to temporarily define global variables and class-wide attributes of the empty class 'router'.
source.py
import wall
def sourcefn():
msg = 'Hello world!'
wall.msg = msg
wall.router.msg = msg
This module imports wall and defines a single function sourcefn
which defines a message and emits it by two different mechanisms, one via globals and one via the router function. Note that the variables wall.msg
and wall.router.message
are defined here for the first time in their respective namespaces.
dest.py
import wall
def destfn():
if hasattr(wall, 'msg'):
print 'global: ' + wall.msg
del wall.msg
else:
print 'global: ' + 'no message'
if hasattr(wall.router, 'msg'):
print 'router: ' + wall.router.msg
del wall.router.msg
else:
print 'router: ' + 'no message'
This module defines a function destfn
which uses the two different mechanisms to receive the messages emitted by source. It allows for the possibility that the variable 'msg' may not exist. destfn
also deletes the variables once they have been displayed.
main.py
import source, dest
source.sourcefn()
dest.destfn() # variables deleted after this call
dest.destfn()
This module calls the previously defined functions in sequence. After the first call to dest.destfn
the variables wall.msg
and wall.router.msg
no longer exist.
The output from the program is:
global: Hello world!
router: Hello world!
global: no message
router: no message
The above code fragments show that the module/global and the class/class variable mechanisms are essentially identical.
If a lot of variables are to be shared, namespace pollution can be managed either by using several wall-type modules, e.g. wall1, wall2 etc. or by defining several router-type classes in a single file. The latter is slightly tidier, so perhaps represents a marginal advantage for use of the class-variable mechanism.

All user installed apks are located in /data/app/, but you can only access this if you are rooted(afaik, you can try without root and if it doesn't work, rooting isn't hard. I suggest you search xda-developers for rooting instructions)
Use Root explorer or ES File Explorer to access /data/app/ (you have to keep going "up" until you reach the root directory /, kind of like C: in windows, before you can see the data directory(folder)). In ES file explorer you must also tick a checkbox in settings to allow going up to the root directory.
When you are in there you will see all your applications apks, though they might be named strangely. Just copy the wanted .apk and paste in the sd card, after that you can copy it to your computer and when you want to install it just open the .apk in a file manager (be sure to have install from unknown sources enabled in android settings). Even if you only want to send over bluetooth I would recommend copying it to the SD first.
PS Note that paid apps probably won't work being copied this way, since they usually check their licence online. PPS Installing an app this way may not link it with google play(you won't see it in my apps and it won't get updates).

What maven does is, it downloads all your project's dependencies into your local repo (.m2 folder). Because of the internet causing issues with your local repo, you project is facing problems. I am not sure if this will surely help you or not but you can try deleting all the files within the repository folder inside the .m2 folder. Since there would be nothing in the local repo, maven would be forced to download the dependencies again, thus forcing an update. Generally, the .m2 folder is located at c:users:[username]:.m2
app.get('/category', function(req, res) {
var string = query
res.redirect('/?valid=' + string);
});
in the ejs you can directly use valid:
<% var k = valid %>
A javascript Object does not have a standard .each function. jQuery provides a function. See http://api.jquery.com/jQuery.each/ The below should work
$.each(object, function(index, value) {
console.log(value);
});
Another option would be to use vanilla Javascript using the Object.keys()
and the Array .map()
functions like this
Object.keys(object).map(function(objectKey, index) {
var value = object[objectKey];
console.log(value);
});
See https://developer.mozilla.org/nl/docs/Web/JavaScript/Reference/Global_Objects/Object/keys and https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
These are usually better than using a vanilla Javascript for-loop, unless you really understand the implications of using a normal for-loop and see use for it's specific characteristics like looping over the property chain.
But usually, a for-loop doesn't work better than jQuery
or Object.keys().map()
. I'll go into two potential issues with using a plain for-loop below.
Right, so also pointed out in other answers, a plain Javascript alternative would be
for(var index in object) {
var attr = object[index];
}
There are two potential issues with this:
1 . You want to check whether the attribute that you are finding is from the object itself and not from up the prototype chain. This can be checked with the hasOwnProperty
function like so
for(var index in object) {
if (object.hasOwnProperty(index)) {
var attr = object[index];
}
}
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/hasOwnProperty for more information.
The jQuery.each
and Object.keys
functions take care of this automatically.
2 . Another potential issue with a plain for-loop is that of scope and non-closures. This is a bit complicated, but take for example the following code. We have a bunch of buttons with ids button0, button1, button2 etc, and we want to set an onclick on them and do a console.log
like this:
<button id='button0'>click</button>
<button id='button1'>click</button>
<button id='button2'>click</button>
var messagesByButtonId = {"button0" : "clicked first!", "button1" : "clicked middle!", "button2" : "clicked last!"];
for(var buttonId in messagesByButtonId ) {
if (messagesByButtonId.hasOwnProperty(buttonId)) {
$('#'+buttonId).click(function() {
var message = messagesByButtonId[buttonId];
console.log(message);
});
}
}
If, after some time, we click any of the buttons we will always get "clicked last!" in the console, and never "clicked first!" or "clicked middle!". Why? Because at the time that the onclick function is executed, it will display messagesByButtonId[buttonId]
using the buttonId
variable at that moment. And since the loop has finished at that moment, the buttonId
variable will still be "button2" (the value it had during the last loop iteration), and so messagesByButtonId[buttonId]
will be messagesByButtonId["button2"]
, i.e. "clicked last!".
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Closures for more information on closures. Especially the last part of that page that covers our example.
Again, jQuery.each
and Object.keys().map()
solve this problem automatically for us, because it provides us with a function(index, value)
(that has closure) so we are safe to use both index and value and rest assured that they have the value that we expect.

If you're working with actual files (as opposed to some sort of string data), how about the following?
$files | % { "$($_.BaseName -replace '_[^_]+$','')$($_.Extension)" }
(or use _.+$
if you want to cut everything from the first underscore.)
You almost always want autocrlf=input
unless you really know what you are doing.
Some additional context below:
It should be either
core.autocrlf=true
if you like DOS ending orcore.autocrlf=input
if you prefer unix-newlines. In both cases, your Git repository will have only LF, which is the Right Thing. The only argument forcore.autocrlf=false
was that automatic heuristic may incorrectly detect some binary as text and then your tile will be corrupted. So,core.safecrlf
option was introduced to warn a user if a irreversable change happens. In fact, there are two possibilities of irreversable changes -- mixed line-ending in text file, in this normalization is desirable, so this warning can be ignored, or (very unlikely) that Git incorrectly detected your binary file as text. Then you need to use attributes to tell Git that this file is binary.
The above paragraph was originally pulled from a thread on gmane.org, but it has since gone down.
That's a good question. I'd love to say “yes”. I can't.
JavaScript is usually considered to have a single thread of execution visible to scripts(*), so that when your inline script, event listener or timeout is entered, you remain completely in control until you return from the end of your block or function.
(*: ignoring the question of whether browsers really implement their JS engines using one OS-thread, or whether other limited threads-of-execution are introduced by WebWorkers.)
However, in reality this isn't quite true, in sneaky nasty ways.
The most common case is immediate events. Browsers will fire these right away when your code does something to cause them:
var l= document.getElementById('log');_x000D_
var i= document.getElementById('inp');_x000D_
i.onblur= function() {_x000D_
l.value+= 'blur\n';_x000D_
};_x000D_
setTimeout(function() {_x000D_
l.value+= 'log in\n';_x000D_
l.focus();_x000D_
l.value+= 'log out\n';_x000D_
}, 100);_x000D_
i.focus();
_x000D_
<textarea id="log" rows="20" cols="40"></textarea>_x000D_
<input id="inp">
_x000D_
Results in log in, blur, log out
on all except IE. These events don't just fire because you called focus()
directly, they could happen because you called alert()
, or opened a pop-up window, or anything else that moves the focus.
This can also result in other events. For example add an i.onchange
listener and type something in the input before the focus()
call unfocuses it, and the log order is log in, change, blur, log out
, except in Opera where it's log in, blur, log out, change
and IE where it's (even less explicably) log in, change, log out, blur
.
Similarly calling click()
on an element that provides it calls the onclick
handler immediately in all browsers (at least this is consistent!).
(I'm using the direct on...
event handler properties here, but the same happens with addEventListener
and attachEvent
.)
There's also a bunch of circumstances in which events can fire whilst your code is threaded in, despite you having done nothing to provoke it. An example:
var l= document.getElementById('log');_x000D_
document.getElementById('act').onclick= function() {_x000D_
l.value+= 'alert in\n';_x000D_
alert('alert!');_x000D_
l.value+= 'alert out\n';_x000D_
};_x000D_
window.onresize= function() {_x000D_
l.value+= 'resize\n';_x000D_
};
_x000D_
<textarea id="log" rows="20" cols="40"></textarea>_x000D_
<button id="act">alert</button>
_x000D_
Hit alert
and you'll get a modal dialogue box. No more script executes until you dismiss that dialogue, yes? Nope. Resize the main window and you will get alert in, resize, alert out
in the textarea.
You might think it's impossible to resize a window whilst a modal dialogue box is up, but not so: in Linux, you can resize the window as much as you like; on Windows it's not so easy, but you can do it by changing the screen resolution from a larger to a smaller one where the window doesn't fit, causing it to get resized.
You might think, well, it's only resize
(and probably a few more like scroll
) that can fire when the user doesn't have active interaction with the browser because script is threaded. And for single windows you might be right. But that all goes to pot as soon as you're doing cross-window scripting. For all browsers other than Safari, which blocks all windows/tabs/frames when any one of them is busy, you can interact with a document from the code of another document, running in a separate thread of execution and causing any related event handlers to fire.
Places where events that you can cause to be generated can be raised whilst script is still threaded:
when the modal popups (alert
, confirm
, prompt
) are open, in all browsers but Opera;
during showModalDialog
on browsers that support it;
the “A script on this page may be busy...” dialogue box, even if you choose to let the script continue to run, allows events like resize and blur to fire and be handled even whilst the script is in the middle of a busy-loop, except in Opera.
a while ago for me, in IE with the Sun Java Plugin, calling any method on an applet could allow events to fire and script to be re-entered. This was always a timing-sensitive bug, and it's possible Sun have fixed it since (I certainly hope so).
probably more. It's been a while since I tested this and browsers have gained complexity since.
In summary, JavaScript appears to most users, most of the time, to have a strict event-driven single thread of execution. In reality, it has no such thing. It is not clear how much of this is simply a bug and how much deliberate design, but if you're writing complex applications, especially cross-window/frame-scripting ones, there is every chance it could bite you — and in intermittent, hard-to-debug ways.
If the worst comes to the worst, you can solve concurrency problems by indirecting all event responses. When an event comes in, drop it in a queue and deal with the queue in order later, in a setInterval
function. If you are writing a framework that you intend to be used by complex applications, doing this could be a good move. postMessage
will also hopefully soothe the pain of cross-document scripting in the future.

If the set of possibilities is "compact" (i.e. largest-value - smallest-value is, say, less than 200) you might consider a lookup table. This would be especially useful if you had a structure like
if (x == 12 || x == 16 || x == 19 || ...)
else if (x==34 || x == 55 || ...)
else if (...)
Set up an array with values identifying the branch to be taken (1, 2, 3 in the example above) and then your tests become
switch(dispatchTable[x])
{
case 1:
...
break;
case 2:
...
break;
case 3:
...
break;
}
Whether or not this is appropriate depends on the semantics of the problem.
If an array isn't appropriate, you could use a Map<Integer,Integer>
, or if you just want to test membership for a single statement, a Set<Integer>
would do. That's a lot of firepower for a simple if
statement, however, so without more context it's kind of hard to guide you in the right direction.
These are the rules of the C++ language:
12
) is a "rvalue"int &ri = 12;
is ill-formedYou have to understand that these are C++ rules. They just are.
It is easy to invent a different language, say C++', with slightly different rules. In C++', it would be permitted to create a non-const reference with a rvalue. There is nothing inconsistent or impossible here.
But it would allow some risky code where the programmer might not get what he intended, and C++ designers rightly decided to avoid that risk.

, and add different file types for different indents,e.g. I want html/rb
indent for 2 spaces, and js/coffee
files indent for 4 spaces:
" by default, the indent is 2 spaces.
set shiftwidth=2
set softtabstop=2
set tabstop=2
" for html/rb files, 2 spaces
autocmd Filetype html setlocal ts=2 sw=2 expandtab
autocmd Filetype ruby setlocal ts=2 sw=2 expandtab
" for js/coffee/jade files, 4 spaces
autocmd Filetype javascript setlocal ts=4 sw=4 sts=0 expandtab
autocmd Filetype coffeescript setlocal ts=4 sw=4 sts=0 expandtab
autocmd Filetype jade setlocal ts=4 sw=4 sts=0 expandtab
This is due to the wp_terms
, wp_termmeta
and wp_term_taxonomy
tables, which had all their ID's not set to AUTO_INCREMENT
To do this go to phpmyadmin, click on the concern database, wp_terms
table, click on structure Tab, at right side you will see a tab named A_I(AUTO_INCREMENT)
, check it and save (You are only doing this for the first option, in the case wp_term
you are only doing it for term_id
).
Do the same for wp_termmeta
and wp_term_taxonomy
that will fix the issue.
Below are the steps to do revoke your JWT access token:
Please let me know if you need more details, I can share the code (Java + Spring boot) as well.
For your questions:
Q1: It's another JWT with fewer claims put in with long expiry time.
Q2: It won't be in a database. The backend will not store anywhere. They will just decrypt the token with private/public key and validate it with its expiry time also.
Q3: Yes, Correct
Another quite fresh test with to_pickle()
.
I have 25 .csv
files in total to process and the final dataframe
consists of roughly 2M items.
(Note: Besides loading the .csv files, I also manipulate some data and extend the data frame by new columns.)
Going through all 25 .csv
files and create the dataframe takes around 14 sec
.
Loading the whole dataframe from a pkl
file takes less than 1 sec
Perhaps the best two browser techs for this are Canvas, with Flash as a back up.
We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.
With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.
In Git, to "fast forward" means to update the HEAD
pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...
Fast forwarding is not possible when the new HEAD
is in a diverged state relative to the stream you want to integrate. For instance, you are on master
and have local commits, and git fetch
has brought new upstream commits into origin/master
. The branch now diverges from its upstream and cannot be fast forwarded: your master
HEAD
commit is not an ancestor of origin/master
HEAD
. To simply reset master
to the value of origin/master
would discard your local commits. The situation requires a rebase or merge.
If your local master
has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master
. Usually, no special steps are needed to do fast-forwarding; it is done by merge
or rebase
in the situation when there are no local commits.
Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?
No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

What are raw types in Java, and why do I often hear that they shouldn't be used in new code?
Raw-types are ancient history of the Java language. In the beginning there were Collections
and they held Objects
nothing more and nothing less. Every operation on Collections
required casts from Object
to the desired type.
List aList = new ArrayList();
String s = "Hello World!";
aList.add(s);
String c = (String)aList.get(0);
While this worked most of the time, errors did happen
List aNumberList = new ArrayList();
String one = "1";//Number one
aNumberList.add(one);
Integer iOne = (Integer)aNumberList.get(0);//Insert ClassCastException here
The old typeless collections could not enforce type-safety so the programmer had to remember what he stored within a collection.
Generics where invented to get around this limitation, the developer would declare the stored type once and the compiler would do it instead.
List<String> aNumberList = new ArrayList<String>();
aNumberList.add("one");
Integer iOne = aNumberList.get(0);//Compile time error
String sOne = aNumberList.get(0);//works fine
For Comparison:
// Old style collections now known as raw types
List aList = new ArrayList(); //Could contain anything
// New style collections with Generics
List<String> aList = new ArrayList<String>(); //Contains only Strings
More complex the Compareable interface:
//raw, not type save can compare with Other classes
class MyCompareAble implements CompareAble
{
int id;
public int compareTo(Object other)
{return this.id - ((MyCompareAble)other).id;}
}
//Generic
class MyCompareAble implements CompareAble<MyCompareAble>
{
int id;
public int compareTo(MyCompareAble other)
{return this.id - other.id;}
}
Note that it is impossible to implement the CompareAble
interface with compareTo(MyCompareAble)
with raw types.
Why you should not use them:
Object
stored in a Collection
has to be cast before it can be usedObject
What the compiler does: Generics are backward compatible, they use the same java classes as the raw types do. The magic happens mostly at compile time.
List<String> someStrings = new ArrayList<String>();
someStrings.add("one");
String one = someStrings.get(0);
Will be compiled as:
List someStrings = new ArrayList();
someStrings.add("one");
String one = (String)someStrings.get(0);
This is the same code you would write if you used the raw types directly. Thought I'm not sure what happens with the CompareAble
interface, I guess that it creates two compareTo
functions, one taking a MyCompareAble
and the other taking an Object
and passing it to the first after casting it.
What are the alternatives to raw types: Use generics
This is what I have setup on my express

Apache Kafka is a popular choice for powering data pipelines. Apache kafka added kafka stream to support popular etl use cases. KSQL makes it simple to transform data within the pipeline, readying messages to cleanly land in another system. KSQL is the streaming SQL engine for Apache Kafka. It provides an easy-to-use yet powerful interactive SQL interface for stream processing on Kafka, without the need to write code in a programming language such as Java or Python. KSQL is scalable, elastic, fault-tolerant, and real-time. It supports a wide range of streaming operations, including data filtering, transformations, aggregations, joins, windowing, and sessionization.
https://docs.confluent.io/current/ksql/docs/index.html
Rabbitmq is not a popular choice for etl systems rather for those systems where it requires simple messaging systems with less throughput.
I would recommend to use date->diff function, as in example below:
$dStart = new DateTime('2012-07-26');
$dEnd = new DateTime('2012-08-26');
$dDiff = $dStart->diff($dEnd);
echo $dDiff->format('%r%a'); // use for point out relation: smaller/greater
This is my basic understanding. It may well be wrong!
$watch
method.$apply
method.$apply
the $digest
method is invoked which goes
through each of the watches and checks to see if they changed since
last time the $digest
ran.In normal development, data-binding syntax in the HTML tells the AngularJS compiler to create the watches for you and controller methods are run inside $apply
already. So to the application developer it is all transparent.
If you are using springboot then jackson is added by default,
So the version of jackson you are adding manualy is probably conflicting with the one spring boot adds,
Try to delete the jackson dependencies from your pom,
If you need to override the version spring boots add, then you need to exclude it first and then add your own

This worked for me,
1. For getting Columns having at least 1 null value. (column names)
data.columns[data.isnull().any()]
2. For getting Columns with count, with having at least 1 null value.
data[data.columns[data.isnull().any()]].isnull().sum()
[Optional] 3. For getting percentage of the null count.
data[data.columns[data.isnull().any()]].isnull().sum() * 100 / data.shape[0]
Generally you shouldn't rely on system properties to configure a webapp - they may be used to configure the container (e.g. Tomcat) but not an application running inside tomcat.
cliff.meyers has already mentioned the way you should rather use for your webapplication. That's the standard way, that also fits your question of being configurable through context.xml or server.xml means.
That said, should you really need system properties or other jvm options (like max memory settings) in tomcat, you should create a file named "bin/setenv.sh" or "bin/setenv.bat". These files do not exist in the standard archive that you download, but if they are present, the content is executed during startup (if you start tomcat via startup.sh/startup.bat). This is a nice way to separate your own settings from the standard tomcat settings and makes updates so much easier. No need to tweak startup.sh or catalina.sh.
(If you execute tomcat as windows servive, you usually use tomcat5w.exe, tomcat6w.exe etc. to configure the registry settings for the service.)
EDIT: Also, another possibility is to go for JNDI Resources.
One can also do this with pylab and xticks

I had input type text field in a table row field. I am targeting it with code
.admin_table input[type=text]:focus

}
While you can use rand(42-10) + 10
to get a random number between 10
and 42
(where 10 is inclusive and 42 exclusive), there's a better way since Ruby 1.9.3, where you are able to call:
rand(10...42) # => 13
Available for all versions of Ruby by requiring my backports
gem.
Ruby 1.9.2 also introduced the Random
class so you can create your own random number generator objects and has a nice API:
r = Random.new
r.rand(10...42) # => 22
r.bytes(3) # => "rnd"
The Random
class itself acts as a random generator, so you call directly:
Random.rand(10...42) # => same as rand(10...42)
Notes on Random.new
In most cases, the simplest is to use rand
or Random.rand
. Creating a new random generator each time you want a random number is a really bad idea. If you do this, you will get the random properties of the initial seeding algorithm which are atrocious compared to the properties of the random generator itself.
If you use Random.new
, you should thus call it as rarely as possible, for example once as MyApp::Random = Random.new
and use it everywhere else.
The cases where Random.new
is helpful are the following:
rand
/Random.rand

In newer versions(>=1.8.0) of docker, you can do this
docker build -f Dockerfile.db .
docker build -f Dockerfile.web .
A big save.
EDIT: update versions per raksja's comment
EDIT: comment from @vsevolod: it's possible to get syntax highlighting in VS code by giving files .Dockerfile extension(instead of name) e.g. Prod.Dockerfile, Test.Dockerfile etc.
In my case junk files from editor caused the problem. I had a config as below:
#...
http {
# ...
include ../sites/*;
}
In the ../sites
directory initially I had a default.config
file.
However, by mistake I saved duplicate files as default.config.save
and default.config.save.1
.
Removing them resolved the issue.
The simplest solution is to apply Python str
function to the column you are trying to loop through.
If you are using pandas
, this can be implemented as:
dataframe['column_name']=dataframe['column_name'].apply(str)
var d = new Date(2011,10,30);
as months are indexed from 0 in js.
@MIP is right, but with newer versions of Safari, you will need to add sandbox attribute(HTML5) to give redirect access to the iFrame. There are a few specific values that can be added with a space between them.
Reference(you will need to scroll): https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe
Ex:
<iframe sandbox="allow-top-navigation" src="http://google.com/"></iframe>
Some browsers support Array.indexOf()
.
If not, you could augment the Array
object via its prototype like so...
if (!Array.prototype.indexOf)
{
Array.prototype.indexOf = function(searchElement /*, fromIndex */)
{
"use strict";
if (this === void 0 || this === null)
throw new TypeError();
var t = Object(this);
var len = t.length >>> 0;
if (len === 0)
return -1;
var n = 0;
if (arguments.length > 0)
{
n = Number(arguments[1]);
if (n !== n) // shortcut for verifying if it's NaN
n = 0;
else if (n !== 0 && n !== (1 / 0) && n !== -(1 / 0))
n = (n > 0 || -1) * Math.floor(Math.abs(n));
}
if (n >= len)
return -1;
var k = n >= 0
? n
: Math.max(len - Math.abs(n), 0);
for (; k < len; k++)
{
if (k in t && t[k] === searchElement)
return k;
}
return -1;
};
}
I have done following and it resolve an issue with recyclerview same you may use for other widget as well if it's not working in eclipse project.
• Go to sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0-rc1 directory
• Copy recyclerview-v7-21.0.0-rc1.aar file and rename it as .zip
• Unzip the file, you will get classes.jar (rename the jar file more meaningful name)
• Use the following jar in your project build path or lib directory.
and it resolve your error.
happy coding :)
Using require.js you can do the same thing in a safer way. You can just define your dependency on jquery and then execute the code you want using the dependency when it is loaded without polluting the namespace:
I generally recommend this library for managing all dependencies on Javascript. It's simple and allows for an efficient optimization of resource loading. However there's some precautions you may need to take when using it with JQuery . My favourite way to deal with them is explained in this github repo and reflected by the following code sample:
<title>jQuery+RequireJS Sample Page</title>
<script src="scripts/require.js"></script>
<script>
require({
baseUrl: 'scripts',
paths: {
jquery: 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min'
},
priority: ['jquery']
}, ['main']);
</script>
Match a regular expression that starts at the beginning ^
or after a space [[:space:]]
and is followed by an alphabetical character [[:alpha:]]
. Globally (the g in gsub) replace all such occurrences with the matched beginning or space and the upper-case version of the matched alphabetical character, \\1\\U\\2
. This has to be done with perl-style regular expression matching.
gsub("(^|[[:space:]])([[:alpha:]])", "\\1\\U\\2", name, perl=TRUE)
# [1] "Zip Code" "State" "Final Count"
In a little more detail for the replacement argument to gsub()
, \\1
says 'use the part of x
matching the first sub-expression', i.e., the part of x
matching (^|[[:spacde:]])
. Likewise, \\2
says use the part of x
matching the second sub-expression ([[:alpha:]])
. The \\U
is syntax enabled by using perl=TRUE
, and means to make the next character Upper-case. So for "Zip code", \\1
is "Zip", \\2
is "code", \\U\\2
is "Code", and \\1\\U\\2
is "Zip Code".
The ?regexp
page is helpful for understanding regular expressions, ?gsub
for putting things together.
Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z]
or [0-9-]
), OR escape it (e.g. [a-z\-0-9]
) in order to add "hyphen" to your class.
It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.
(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]
) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)
Great question!
As a developer, you should probably start learning set operations (difference, union, intersection). You can imagine your array as one "set", and the keys you are searching for the other.
function in_array_all($needles, $haystack) {
return empty(array_diff($needles, $haystack));
}
echo in_array_all( [3,2,5], [5,8,3,1,2] ); // true, all 3, 2, 5 present
echo in_array_all( [3,2,5,9], [5,8,3,1,2] ); // false, since 9 is not present
function in_array_any($needles, $haystack) {
return !empty(array_intersect($needles, $haystack));
}
echo in_array_any( [3,9], [5,8,3,1,2] ); // true, since 3 is present
echo in_array_any( [4,9], [5,8,3,1,2] ); // false, neither 4 nor 9 is present
See:
The Difference Between a Program and a Script
A Script is also a program but without an opaque layer hiding the (source code) whereas a program is one having clothes, you can't see it's source code unless it is decompilable.
Scripts need other programs to execute them while programs don't need one.

The Date
documentation states that :
The JavaScript date is based on a time value that is milliseconds since midnight January 1, 1970, UTC
Click on start button then on end button. It will show you the number of seconds between the 2 clicks.
The milliseconds diff is in variable timeDiff
. Play with it to find seconds/minutes/hours/ or what you need
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = new Date();_x000D_

var timeDiff = endTime - startTime; //in ms_x000D_
// strip the ms_x000D_
timeDiff /= 1000;_x000D_
_x000D_
// get seconds _x000D_
var seconds = Math.round(timeDiff);_x000D_
console.log(seconds + " seconds");_x000D_
}
_x000D_
<button onclick="start()">Start</button>_x000D_

<button onclick="end()">End</button>
_x000D_
OR another way of doing it for modern browser
Using performance.now()
which returns a value representing the time elapsed since the time origin. This value is a double with microseconds in the fractional.
The time origin is a standard time which is considered to be the beginning of the current document's lifetime.
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = performance.now();_x000D_

The solution is already answered here above (long ago).
But the implicit question "why does it work in FF and IE but not in Chrome and Safari" is found in the error text "Not allowed to load local resource": Chrome and Safari seem to use a more strict implementation of sandboxing (for security reasons) than the other two (at this time 2011).
This applies for local access. In a (normal) server environment (apache ...) the file would simply not have been found.
control + shift + F will do the work
If you just want the difference in years, there's:
SELECT EXTRACT(YEAR FROM date1) - EXTRACT(YEAR FROM date2) FROM mytable
Or do you want fractional years as well?
SELECT (date1 - date2) / 365.242199 FROM mytable
365.242199 is 1 year in days, according to Google.
Building on the answer from @fzzle - to achieve a circle from a rectangle without defining a fixed height or width, the following will work. The padding-top:100% keeps a 1:1 ratio for the circle-cropper div. Set an inline background image, center it, and use background-size:cover to hide any excess.
CSS
.circle-cropper {
background-repeat: no-repeat;
background-size: cover;
background-position: 50%;
border-radius: 50%;
width: 100%;
padding-top: 100%;
}
HTML
<div class="circle-cropper" role="img" style="background-image:url(myrectangle.jpg);"></div>

clip-path
is now (2020) the best way I have found to achieve box-shadows on specific sides of elements, especially when the required effect is a "clean cut" shadow at particular edges, like this:
.shadow-element {
width: 100px;
height: 100px;
background-color: #FFC300;
box-shadow: 0 0 10px 5px rgba(0,0,0,0.75);
clip-path: inset(0px -15px 0px -15px);
/* position and left properties required to bring element out from edge of parent
so that shadow can be seen; margin-left would also achieve the same thing */
position: relative;
left: 15px;
}
_x000D_
<div class="shadow-element"></div>
_x000D_
...as opposed to an attenuated/reduced/thinning shadow like this:
.shadow-element {
width: 100px;
height: 100px;
background-color: #FFC300;
box-shadow: 15px 0 15px -10px rgba(0,0,0,0.75), -15px 0 15px -10px rgba(0,0,0,0.75);
/* position and left properties required to bring element out from edge of parent
so that shadow can be seen; margin-left would also achieve the same thing */
position: relative;
left: 15px;
}
_x000D_
<div class="shadow-element"></div>
_x000D_
Simply apply the following CSS to the element in question:
box-shadow: 0 0 Xpx Ypx [hex/rgba]; /* note 0 offset values */
clip-path: inset(Apx Bpx Cpx Dpx);
Where:
Apx
sets the shadow visibility for the top edgeBpx
rightCpx
bottomDpx
leftEnter a value of 0 for any edges where the shadow should be hidden and a negative value (the same as the combined result of the blur radius + spread values - Xpx + Ypx
) to any edges where the shadow should be displayed.
One of the options is to use the Javascript.

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.
Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.
In this case I'd ask why you're including both cstdlib
and stdlib.h
; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib
puts them in the namespace std
in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!
Anyway, your use of using namespace std
(which I would recommend against, in future) means that std::system
from cstdlib
now conflicts with system
from stdlib.h
. I can't explain what's going on with std::cout
and std::cin
.
Try removing #include <stdlib.h>
and see what happens.
If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.
Another way: (Since SQL Server 2012)
SELECT
DATEFROMPARTS(YEAR(GETDATE()), 1, 1) FirstDay,
DATEFROMPARTS(YEAR(GETDATE()),12,31) LastDay
I like the following approach as it works for all situations:
$(':focus').blur();
If you don't need VML and IE8 support then use Canvas (PaperJS for example). Look at latest IE10 demos for Windows 7. They have amazing animations in Canvas. SVG is not capable to do anything close to them. Overall Canvas is available at all mobile browsers. SVG is not working at early versions of Android 2.0- 2.3 (as I know)
Yes, Canvas is not scalable, but it so fast that you can redraw the whole canvas faster then browser capable to scroll view port.
From my perspective Microsoft's optimizations provides means to use Canvas as regular GDI engine and implement graphics applications like we do them for Windows now.
With the expression API, which based on the comments is what this question is asking for, you can use the in_
method of the relevant column.
To query
SELECT id, name FROM user WHERE id in (123,456)
use
myList = [123, 456]
select = sqlalchemy.sql.select([user_table.c.id, user_table.c.name], user_table.c.id.in_(myList))
result = conn.execute(select)
for row in result:
process(row)
This assumes that user_table
and conn
have been defined appropriately.
plot "data.dat" using 2: xtic(1) with histogram
Here data.dat contains data of the form
title 1 title2 3 "long title" 5
I suggest using a DataTable.DefaultView as a DataSource. Then the line below.
foreach (DataGridViewColumn column in gridview.Columns)
{
column.SortMode = DataGridViewColumnSortMode.Automatic;
}
After that the gridview itself will manage sorting(Ascending or Descending is supported.)
In my case I signed with only V2 signature (from Android 7 onward) but tried to install on 5 and 6. Adding V1 during ARK generation/signing fixed the issue.
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.

You missed the *
in front of NgIf (like we all have, dozens of times):
<div *ngIf="answer.accepted">✔</div>
Without the *
, Angular sees that the ngIf
directive is being applied to the div
element, but since there is no *
or <template>
tag, it is unable to locate a template, hence the error.
If you get this error with Angular v5:
Error: StaticInjectorError[TemplateRef]:
StaticInjectorError[TemplateRef]:
NullInjectorError: No provider for TemplateRef!
You may have <template>...</template>
in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>
.
It sounds like the web server on hosttwo.com doesn't allow undefined domains to be passed through. You also said you wanted to do a redirect, this isn't actually a method for redirecting. If you bought this domain through GoDaddy you may just want to use their redirection service.
In a nutshell :
List/Array Sort() :
OrderBy/ThenBy() :
x => x.Id
). All keys are extracted first before sorting. This might result in better performance than using Sort() and a custom comparer. Sources: MDSN, reference source and dotnet/coreclr repository (GitHub).
Some of the statements listed above are based on current .NET framework implementation (4.7.2). It might change in the future.
