This exception message doesn't mean it requires a primary key to be defined in your database, it means it requires a primary key to be defined in your class.
Although you've attempted to do so:
private Guid _id; [Key] public Guid ID { get { return _id; } }
This has no effect, as Entity Framework ignores read-only properties. It has to: when it retrieves a Fruits
record from the database, it constructs a Fruit
object, and then calls the property setters for each mapped property. That's never going to work for read-only properties.
You need Entity Framework to be able to set the value of ID
. This means the property needs to have a setter.
Overwrite the dataframe with something like that
import pandas as pd
df = pd.DataFrame(None)
or if you want to keep columns in place
df = pd.DataFrame(columns=df.columns)
Building on the answers of prufrofro and Frank van Puffelen here, I put together this setup that doesn't prevent scraping, but can make it slightly harder to use your API key.
Warning: To get your data, even with this method, one can for example simply open the JS console in Chrome and type:
firebase.database().ref("/get/all/the/data").once("value", function (data) {
console.log(data.val());
});
Only the database security rules can protect your data.
Nevertheless, I restricted my production API key use to my domain name like this:
projectname.firebaseapp.com/*
)Now the app will only work on this specific domain name. So I created another API Key that will be private for localhost developement.
By default, as mentioned by Emmanuel Campos, Firebase only whitelists localhost
and your Firebase hosting domain.
In order to make sure I don't publish the wrong API key by mistake, I use one of the following methods to automatically use the more restricted one in production.
Setup for Create-React-App
In /env.development
:
REACT_APP_API_KEY=###dev-key###
In /env.production
:
REACT_APP_API_KEY=###public-key###
In /src/index.js
const firebaseConfig = {
apiKey: process.env.REACT_APP_API_KEY,
// ...
};

I had the issue during transformClassesWithDexFor when the maximum heap size for the Gradle daemon is superior to 4Go. By changing my ~/gradle.properties with org.gradle.jvmargs=-Xmx2048m (meaning I reduce the heap size to 2Go instead of 4Go) the dex then runs in a separate process and I no longer have the issue.
14:52:26.412 [WARN] [org.gradle.api.Project]
Running dex as a separate process.
To run dex in process, the Gradle daemon needs a larger heap.
It currently has 2048 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to at least 4608 MB (based on the dexOptions.javaMaxHeapSize = 4g).
To do this set org.gradle.jvmargs=-Xmx4608M in the project gradle.properties.
If you call this function then you easily get the client's IP address. I have already used this in my existing project:
public function getUserIpAddr(){
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
In my case, IGListKit refactored their class named IGListSectionController to ListSectionController , while I already had a class named ListSectionController. I used find and replace and didn't know I had a class with the same name.

I read the error message in full and concluded that this error can also happen when you have Circular dependencies. This wasn't mentioned in any of the comments, I hope this helps.
When the length of v will be zero, it'll give you the value error.
You should check the length or you should check the list first whether it is none or not.

The WebRTC API can be used to retrieve the client's local IP.
However the browser may not support it, or the client may have disabled it for security reasons. In any case, one should not rely on this "hack" on the long term as it is likely to be patched in the future (see Cullen Fluffy Jennings's answer).
The ECMAScript 6 code below demonstrates how to do that.
/* ES6 */
const findLocalIp = (logInfo = true) => new Promise( (resolve, reject) => {
window.RTCPeerConnection = window.RTCPeerConnection
|| window.mozRTCPeerConnection
|| window.webkitRTCPeerConnection;
if ( typeof window.RTCPeerConnection == 'undefined' )
return reject('WebRTC not supported by browser');
let pc = new RTCPeerConnection();
let ips = [];
pc.createDataChannel("");
pc.createOffer()
.then(offer => pc.setLocalDescription(offer))
.catch(err => reject(err));
pc.onicecandidate = event => {
if ( !event || !event.candidate ) {
// All ICE candidates have been sent.
if ( ips.length == 0 )
return reject('WebRTC disabled or restricted by browser');
return resolve(ips);
}
let parts = event.candidate.candidate.split(' ');
let [base,componentId,protocol,priority,ip,port,,type,...attr] = parts;
let component = ['rtp', 'rtpc'];
if ( ! ips.some(e => e == ip) )
ips.push(ip);
if ( ! logInfo )
return;
console.log(" candidate: " + base.split(':')[1]);
console.log(" component: " + component[componentId - 1]);
console.log(" protocol: " + protocol);
console.log(" priority: " + priority);
console.log(" ip: " + ip);
console.log(" port: " + port);
console.log(" type: " + type);
if ( attr.length ) {
console.log("attributes: ");
for(let i = 0; i < attr.length; i += 2)
console.log("> " + attr[i] + ": " + attr[i+1]);
}
console.log();
};
} );
Notice I write return resolve(..)
or return reject(..)
as a shortcut. Both of those functions do not return anything.
Then you may have something this :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Local IP</title>
</head>
<body>
<h1>My local IP is</h1>
<p id="ip">Loading..</p>
<script src="ip.js"></script>
<script>
let p = document.getElementById('ip');
findLocalIp().then(
ips => {
let s = '';
ips.forEach( ip => s += ip + '<br>' );
p.innerHTML = s;
},
err => p.innerHTML = err
);
</script>
</body>
</html>
replace:
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
with:
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
if (isset($_POST['newsletter'])) {
$checkBoxValue = "yes";
} else {
$checkBoxValue = "no";
}
then replace this line of code:
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $name \n Email: $email_address \n Tel \n $message\n Newsletter \n $newsletter"
with:
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $name \n Email: $email_address \n Tel \n $message\n Newsletter \n $newsletter";

Just a sub answer:
Absolutely use translated urls with a language identifier in front of them: http://www.domain.com/nl/over-ons
Hybride solutions tend to get complicated, so I would just stick with it. Why? Cause the url is essential for SEO.
About the db translation: Is the number of languages more or less fixed? Or rather unpredictable and dynamic? If it is fixed, I would just add new columns, otherwise go with multiple tables.
But generally, why not use Drupal? I know everybody wants to build their own CMS cause it's faster, leaner, etc. etc. But that is just really a bad idea!
Consider Moshi's JsonWriter class (source). It has a wonderful API and it reduces copying to a minimum, everything is nicely streamed to the OutputStream.
OutputStream os = ...;

.name("type").value(methodn)
...
.endObject();
You can't use PHP in the WordPress back-end Page editor. Maybe with a plugin you can, but not out of the box.
The easiest solution for this is creating a shortcode. Then you can use something like this
function input_func( $atts ) {
extract( shortcode_atts( array(
'type' => 'text',
'name' => '',
), $atts ) );
return '<input name="' . $name . '" id="' . $name . '" value="' . (isset($_GET\['from'\]) && $_GET\['from'\] ? $_GET\['from'\] : '') . '" type="' . $type . '" />';
}
add_shortcode( 'input', 'input_func' );
See the Shortcode_API.

There are many questions about REST auth patterns here on SO. These are the most relevant for your question:
Basically you need to choose between using API keys (least secure as the key may be discovered by an unauthorized user), an app key and token combo (medium), or a full OAuth implementation (most secure).
You may also do the following in Python 3.6.1
from Object import Object as Parent
and your class definition to:
class Visitor(Parent):
Proxies may send a HTTP_X_FORWARDED_FOR
header but even that is optional.
Also keep in mind that visitors may share IP addresses; University networks, large companies and third-world/low-budget ISPs tend to share IPs over many users.
The User Country API has exactly what you need. Here is a sample code using file_get_contents() as you originally do:
$result = json_decode(file_get_contents('http://usercountry.com/v1.0/json/'.$cip), true);
$result['country']['name']; // this contains what you need
Please note that the error is Out of memory
and is not Allowed memory size [..] exhausted
.
So the memory leak is elsewhere on the system. It's possible that mysql server use a lot of system memory after this heavy query, leaving apache/php without it physical and swap.
This should explain the error always on the same line (and/or in the same script).
I don't believe the currently accepted answer is correct. For example, I have the following .htaccess
file in the root of a virtual server (apache 2.4):
<Files "reminder.php">
require all denied
require host localhost
require ip 127.0.0.1
require ip xxx.yyy.zzz.aaa
</Files>
This prevents external access to reminder.php
which is in a subdirectory.
I have a similar .htaccess
file on my Apache 2.2 server with the same effect:
<Files "reminder.php">
Order Deny,Allow
Deny from all
Allow from localhost
Allow from 127.0.0.1
Allow from xxx.yyy.zzz.aaa
</Files>
I don't know for sure but I suspect it's the attempt to define the subdirectory specifically in the .htaccess
file, viz <Files ./inscription/log.txt>
which is causing it to fail. It would be simpler to put the .htaccess
file in the same directory as log.txt
i.e. in the inscription
directory and it will work there.
document.forms[ 'forms1' ].onsubmit = function() {
return [].some.call( this.elements, function( el ) {
return el.type === 'radio' ? el.checked : false
} )
}
Just something out of my head. Not sure the code is working.
See my jsFiddle here: http://jsfiddle.net/fuDBL/
Whenever you change the email field, the link is updated automatically. This requires a small amount of jQuery. So now your form will work as needed, but your link will be updated dynamically so that when someone clicks on it, it contains what they entered in the email field. You should validate the input on the receiving page.
$('input[name="email"]').change(function(){
$('#regLink').attr('href')+$('input[name="email"]').val();
});
Uninstallation :
sudo /Library/PostgreSQL/9.6/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh
Removing the data file :
sudo rm -rf /Library/PostgreSQL
Removing the configs :
sudo rm /etc/postgres-reg.ini
And thats it.
If, like me, you want to make a function pack or something that people can download then it's very simple. Just write your function in a python file and save it as the name you want IN YOUR PYTHON DIRECTORY. Now, in your script where you want to use this, you type:
from FILE NAME import FUNCTION NAME
Note - the parts in capital letters are where you type the file name and function name.
Now you just use your function however it was meant to be.
Example:
FUNCTION SCRIPT - saved at C:\Python27 as function_choose.py
def choose(a):
from random import randint
b = randint(0, len(a) - 1)
c = a[b]
return(c)
SCRIPT USING FUNCTION - saved wherever
from function_choose import choose
list_a = ["dog", "cat", "chicken"]
print(choose(list_a))
OUTPUT WILL BE DOG, CAT, OR CHICKEN
Hoped this helped, now you can create function packs for download!

Hiding HTML source isn't really possible. Disabling right-click only frustrates users who wish to do something constructive with your content (copy/paste content or forms, or print, for example).
If you're running a server-side scripting language you could obfuscate or minify the HTML, CSS and Javascript. This will make it harder for someone to copy your code or see how you've achieved certain effects.

return object : TypeToken<List<T>>() {}.type

If you use Nginx behind other balancer, for instance AWS Application Balancer, HTTP_X_FORWARDED_FOR returns list of addresses. It can be fixed like that:

ip_list = proxy_data.split(',')
user_ip = ip_list[0] # first address in list is User IP
else:
user_ip = request.remote_addr # For local development

For developers looking for a full-featured geolocation utility, you can have a look at geolocator.js (I'm the author).
Example below will first try HTML5 Geolocation API to obtain the exact coordinates. If fails or rejected, it will fallback to Geo-IP look-up. Once it gets the coordinates, it will reverse-geocode the coordinates into an address.
var options = {
enableHighAccuracy: true,
timeout: 6000,
maximumAge: 0,
desiredAccuracy: 30,
fallbackToIP: true, // if HTML5 geolocation fails or rejected
addressLookup: true, // get detailed address information
timezone: true,
map: "my-map" // this will even create a map for you
};
geolocator.locate(options, function (err, location) {
console.log(err || location);
});
It supports geo-location (via HTML5 or IP lookups), geocoding, address look-ups (reverse geocoding), distance & durations, timezone information and more...

You could manually set the cookie, but depending on your use case (and if you might want to add more types of persistent/session data in future) it might make more sense to use Django's sessions feature. This will let you get and set variables tied internally to the user's session cookie. Cool thing about this is that if you want to store a lot of data tied to a user's session, storing it all in cookies will add a lot of weight to HTTP requests and responses. With sessions the session cookie is all that is sent back and forth (though there is the overhead on Django's end of storing the session data to keep in mind).
For easier use CI have updated this so you can just use
$this->load->helper('language');
and to translate text
lang('language line');
and if you want to warp it inside label then use optional parameter
lang('language line', 'element id');
This will output
// becomes <label for="form_item_id">language_key</label>

A solution that would conform to W3C standards would be to create a transparent div (for example dynamically with JavaScript), set its width and height to 100vw/100vh (Viewport units) and then get its offsetWidth and offsetHeight. After that, the element can be removed again. This will not work in older browsers because the viewport units are relatively new, but if you don't care about them but about (soon-to-be) standards instead, you could definitely go this way:
var objNode = document.createElement("div");
objNode.style.width = "100vw";
objNode.style.height = "100vh";
document.body.appendChild(objNode);
var intViewportWidth = objNode.offsetWidth;
var intViewportHeight = objNode.offsetHeight;
document.body.removeChild(objNode);
Of course, you could also set objNode.style.position = "fixed" and then use 100% as width/height - this should have the same effect and improve compatibility to some extent. Also, setting position to fixed might be a good idea in general, because otherwise the div will be invisible but consume some space, which will lead to scrollbars appearing etc.

I wrote a bot using an API from ipapi.co, here's how you can get location for an IP address (e.g. 1.2.3.4
) in php
:
Set header :
$opts = array('http'=>array('method'=>"GET", 'header'=>"User-Agent: mybot.v0.7.1"));
$context = stream_context_create($opts);
Get JSON response
echo file_get_contents('https://ipapi.co/1.2.3.4/json/', false, $context);
of get a specific field (country, timezone etc.)
echo file_get_contents('https://ipapi.co/1.2.3.4/country/', false, $context);
Visitor allows one to add new virtual functions to a family of classes without modifying the classes themselves; instead, one creates a visitor class that implements all of the appropriate specializations of the virtual function
Visitor structure:
Use Visitor pattern if:
Even though Visitor pattern provides flexibility to add new operation without changing the existing code in Object, this flexibility has come with a drawback.
If a new Visitable object has been added, it requires code changes in Visitor & ConcreteVisitor classes. There is a workaround to address this issue : Use reflection, which will have impact on performance.
Code snippet:
import java.util.HashMap;
interface Visitable{
void accept(Visitor visitor);
}
interface Visitor{
void logGameStatistics(Chess chess);
void logGameStatistics(Checkers checkers);
void logGameStatistics(Ludo ludo);
}
class GameVisitor implements Visitor{
public void logGameStatistics(Chess chess){
System.out.println("Logging Chess statistics: Game Completion duration, number of moves etc..");
}
public void logGameStatistics(Checkers checkers){
System.out.println("Logging Checkers statistics: Game Completion duration, remaining coins of loser");
}
public void logGameStatistics(Ludo ludo){
System.out.println("Logging Ludo statistics: Game Completion duration, remaining coins of loser");
}
}
abstract class Game{
// Add game related attributes and methods here
public Game(){
}
public void getNextMove(){};
public void makeNextMove(){}
public abstract String getName();
}
class Chess extends Game implements Visitable{
public String getName(){
return Chess.class.getName();
}
public void accept(Visitor visitor){
visitor.logGameStatistics(this);
}
}
class Checkers extends Game implements Visitable{
public String getName(){
return Checkers.class.getName();
}
public void accept(Visitor visitor){
visitor.logGameStatistics(this);
}
}
class Ludo extends Game implements Visitable{
public String getName(){
return Ludo.class.getName();
}
public void accept(Visitor visitor){
visitor.logGameStatistics(this);
}
}
public class VisitorPattern{
public static void main(String args[]){
Visitor visitor = new GameVisitor();
Visitable games[] = { new Chess(),new Checkers(), new Ludo()};
for (Visitable v : games){
v.accept(visitor);
}
}
}
Explanation:
Visitable
(Element
) is an interface and this interface method has to be added to a set of classes. Visitor
is an interface, which contains methods to perform an operation on Visitable
elements.GameVisitor
is a class, which implements Visitor
interface ( ConcreteVisitor
).Visitable
element accept Visitor
and invoke a relevant method of Visitor
interface.Game
as Element
and concrete games like Chess,Checkers and Ludo
as ConcreteElements
.In above example, Chess, Checkers and Ludo
are three different games ( and Visitable
classes). On one fine day, I have encountered with a scenario to log statistics of each game. So without modifying individual class to implement statistics functionality, you can centralise that responsibility in GameVisitor
class, which does the trick for you without modifying the structure of each game.
output:
Logging Chess statistics: Game Completion duration, number of moves etc..
Logging Checkers statistics: Game Completion duration, remaining coins of loser
Logging Ludo statistics: Game Completion duration, remaining coins of loser

pattern allows behaviour to be added to an individual object, either statically or dynamically, without affecting the behaviour of other objects from the same class

You could use getSelectedObjects() of ItemSelectable (superinterface of ButtonModel) which returns the list of selected items. In case of a radio button group it can only be one or none at all.
The following command works for Screen version 4.06.02:
screen -L -Logfile Log_file_name_of_your_choice command_to_be_executed
From the man page of Screen:
-Logfile file : By default logfile name is "screenlog.0".
You can set new logfile name with the "-Logfile" option.
You can check the existing version of Screen using screen -version. You can download and install the latest Screen version from https://www.gnu.org/software/screen/.
As for adding a dependency, I'm afraid the java.util.Date & .Calendar really are so bad that the first thing I do to any new project is add the Joda-Time library. In Java 8 you can use the new java.time package, inspired by Joda-Time.
The core of Joda-Time is the DateTime
class. Unlike java.util.Date, it understands its assigned time zone (DateTimeZone
). When converting from j.u.Date, assign a zone.
DateTimeZone zone = DateTimeZone.forID( "America/Montreal" );
DateTime dateTimeQuébec = new DateTime( date , zone );
LocalDate
One way to verify if two date-times land on the same date is to convert to LocalDate
objects.
That conversion depends on the assigned time zone. To compare LocalDate
objects, they must have been converted with the same zone.
Here is a little utility method.
static public Boolean sameDate ( DateTime dt1 , DateTime dt2 )
{
LocalDate ld1 = new LocalDate( dt1 );
// LocalDate determination depends on the time zone.
// So be sure the date-time values are adjusted to the same time zone.
LocalDate ld2 = new LocalDate( dt2.withZone( dt1.getZone() ) );
Boolean match = ld1.equals( ld2 );
return match;
}
Better would be another argument, specifying the time zone rather than assuming the first DateTime object’s time zone should be used.
static public Boolean sameDate ( DateTimeZone zone , DateTime dt1 , DateTime dt2 )
{
LocalDate ld1 = new LocalDate( dt1.withZone( zone ) );
// LocalDate determination depends on the time zone.
// So be sure the date-time values are adjusted to the same time zone.
LocalDate ld2 = new LocalDate( dt2.withZone( zone ) );
return ld1.equals( ld2 );
}
Another approach is to create a string representation of the date portion of each date-time, then compare strings.
Again, the assigned time zone is crucial.
DateTimeFormatter formatter = ISODateTimeFormat.date(); // Static method.
String s1 = formatter.print( dateTime1 );
String s2 = formatter.print( dateTime2.withZone( dt1.getZone() ) );
Boolean match = s1.equals( s2 );
return match;
The generalized solution is to define a span of time, then ask if the span contains your target. This example code is in Joda-Time 2.4. Note that the "midnight"-related classes are deprecated. Instead use the withTimeAtStartOfDay
method. Joda-Time offers three classes to represent a span of time in various ways: Interval, Period, and Duration.
Using the "Half-Open" approach where the beginning of the span is inclusive and the ending exclusive.
The time zone of the target can be different than the time zone of the interval.
DateTimeZone timeZone = DateTimeZone.forID( "Europe/Paris" );
DateTime target = new DateTime( 2012, 3, 4, 5, 6, 7, timeZone );
DateTime start = DateTime.now( timeZone ).withTimeAtStartOfDay();
DateTime stop = start.plusDays( 1 ).withTimeAtStartOfDay();
Interval interval = new Interval( start, stop );
boolean containsTarget = interval.contains( target );
Java 8 and later comes with the java.time framework. Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project. See Tutorial.
The makers of Joda-Time have instructed us all to move to java.time as soon as is convenient. In the meantime Joda-Time continues as an actively maintained project. But expect future work to occur only in java.time and ThreeTen-Extra rather than Joda-Time.
To summarize java.time in a nutshell… An Instant
is a moment on the timeline in UTC. Apply a time zone (ZoneId
) to get a ZonedDateTime
object. To move off the timeline, to get the vague indefinite idea of a date-time, use the "local" classes: LocalDateTime
, LocalDate
, LocalTime
.
The logic discussed in the Joda-Time section of this Answer applies to java.time.
The old java.util.Date class has a new toInstant
method for conversion to java.time.
Instant instant = yourJavaUtilDate.toInstant(); // Convert into java.time type.
Determining a date requires a time zone.
ZoneId zoneId = ZoneId.of( "America/Montreal" );
We apply that time zone object to the Instant
to obtain a ZonedDateTime
. From that we extract a date-only value (a LocalDate
) as our goal is to compare dates (not hours, minutes, etc.).
ZonedDateTime zdt1 = ZonedDateTime.ofInstant( instant , zoneId );
LocalDate localDate1 = LocalDate.from( zdt1 );
Do the same to the second java.util.Date
object we need for comparison. I’ll just use the current moment instead.
ZonedDateTime zdt2 = ZonedDateTime.now( zoneId );
LocalDate localDate2 = LocalDate.from( zdt2 );
Use the special isEqual
method to test for the same date value.
Boolean sameDate = localDate1.isEqual( localDate2 );

On Xcode 11 / macOS Catalina, the header files are no longer in the old location and the old /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
file is no longer available.
Instead, the headers are now installed to the /usr/include
directory of the current SDK path:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include
Most of this directory can be found by using the output of xcrun --show-sdk-path
. And if you add this path to the CPATH
environment variable, then build scripts (including those called via bundle
) will generally be able to find it.
I resolved this by setting my CPATH
in my .zshrc
file:
export CPATH="$(xcrun --show-sdk-path)/usr/include"
After opening a new shell (or running source .zshrc
), I no longer receive the error message mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h and the rubygems install properly.
Note on Building to Non-macOS Platforms
If you are building to non-macOS platforms, such as iOS/tvOS/watchOS, this change will attempt to include the macOS SDK in those platforms, causing build errors. To resolve, either don't set
CPATH
environment variable on login, or temporarily set it to blank when runningxcodebuild
like so:CPATH="" xcodebuild --some-args
We will look at how the contents of this array are constructed and can be manipulated to affect where the Perl interpreter will find the module files.
Default @INC
Perl interpreter is compiled with a specific @INC
default value. To find out this value, run env -i perl -V
command (env -i
ignores the PERL5LIB
environmental variable - see #2) and in the output you will see something like this:
$ env -i perl -V ... @INC: /usr/lib/perl5/site_perl/5.18.0/x86_64-linux-thread-multi-ld /usr/lib/perl5/site_perl/5.18.0 /usr/lib/perl5/5.18.0/x86_64-linux-thread-multi-ld /usr/lib/perl5/5.18.0 .
Note .
at the end; this is the current directory (which is not necessarily the same as the script's directory). It is missing in Perl 5.26+, and when Perl runs with -T
(taint checks enabled).
To change the default path when configuring Perl binary compilation, set the configuration option otherlibdirs
:
Configure -Dotherlibdirs=/usr/lib/perl5/site_perl/5.16.3
Environmental variable PERL5LIB
(or PERLLIB
)
Perl pre-pends @INC
with a list of directories (colon-separated) contained in PERL5LIB
(if it is not defined, PERLLIB
is used) environment variable of your shell. To see the contents of @INC
after PERL5LIB
and PERLLIB
environment variables have taken effect, run perl -V
.
$ perl -V ... %ENV: PERL5LIB="/home/myuser/test" @INC: /home/myuser/test /usr/lib/perl5/site_perl/5.18.0/x86_64-linux-thread-multi-ld /usr/lib/perl5/site_perl/5.18.0 /usr/lib/perl5/5.18.0/x86_64-linux-thread-multi-ld /usr/lib/perl5/5.18.0 .
-I
command-line option
Perl pre-pends @INC
with a list of directories (colon-separated) passed as value of the -I
command-line option. This can be done in three ways, as usual with Perl options:
Pass it on command line:
perl -I /my/moduledir your_script.pl
Pass it via the first line (shebang) of your Perl script:
#!/usr/local/bin/perl -w -I /my/moduledir
Pass it as part of PERL5OPT
(or PERLOPT
) environment variable (see chapter 19.02 in Programming Perl)
Pass it via the lib
pragma
Perl pre-pends @INC
with a list of directories passed in to it via use lib
.
In a program:
use lib ("/dir1", "/dir2");
On the command line:
perl -Mlib=/dir1,/dir2
You can also remove the directories from @INC
via no lib
.
You can directly manipulate @INC
as a regular Perl array.
Note: Since @INC
is used during the compilation phase, this must be done inside of a BEGIN {}
block, which precedes the use MyModule
statement.
Add directories to the beginning via unshift @INC, $dir
.
Add directories to the end via push @INC, $dir
.
Do anything else you can do with a Perl array.
Note: The directories are unshifted onto @INC
in the order listed in this answer, e.g. default @INC
is last in the list, preceded by PERL5LIB
, preceded by -I
, preceded by use lib
and direct @INC
manipulation, the latter two mixed in whichever order they are in Perl code.
@INC
?There does not seem to be a comprehensive @INC
FAQ-type post on Stack Overflow, so this question is intended as one.
If the modules in a directory need to be used by many/all scripts on your site, especially run by multiple users, that directory should be included in the default @INC
compiled into the Perl binary.
If the modules in the directory will be used exclusively by a specific user for all the scripts that user runs (or if recompiling Perl is not an option to change default @INC
in previous use case), set the users' PERL5LIB
, usually during user login.
Note: Please be aware of the usual Unix environment variable pitfalls - e.g. in certain cases running the scripts as a particular user does not guarantee running them with that user's environment set up, e.g. via su
.
If the modules in the directory need to be used only in specific circumstances (e.g. when the script(s) is executed in development/debug mode, you can either set PERL5LIB
manually, or pass the -I
option to perl.
If the modules need to be used only for specific scripts, by all users using them, use use lib
/no lib
pragmas in the program itself. It also should be used when the directory to be searched needs to be dynamically determined during runtime - e.g. from the script's command line parameters or script's path (see the FindBin module for very nice use case).
If the directories in @INC
need to be manipulated according to some complicated logic, either impossible to too unwieldy to implement by combination of use lib
/no lib
pragmas, then use direct @INC
manipulation inside BEGIN {}
block or inside a special purpose library designated for @INC
manipulation, which must be used by your script(s) before any other modules are used.
An example of this is automatically switching between libraries in prod/uat/dev directories, with waterfall library pickup in prod if it's missing from dev and/or UAT (the last condition makes the standard "use lib + FindBin" solution fairly complicated. A detailed illustration of this scenario is in How do I use beta Perl modules from beta Perl scripts?.
An additional use case for directly manipulating @INC
is to be able to add subroutine references or object references (yes, Virginia, @INC
can contain custom Perl code and not just directory names, as explained in When is a subroutine reference in @INC called?).
In my case I had to put it in the bin folder of my project even the fact that my classpath is set to the src folder. I have no idea why, but it's worth a try.

bool findStringIC(const std::string & strHaystack, const std::string & strNeedle)
{
auto it = std::search(
strHaystack.begin(), strHaystack.end(),
strNeedle.begin(), strNeedle.end(),
[](char ch1, char ch2) { return std::toupper(ch1) == std::toupper(ch2); }
);
return (it != strHaystack.end() );
}

Use the utf8 module from npm to encode/decode the string.
Installation:
npm install utf8
In a browser:
<script src="utf8.js"></script>
In Node.js:
const utf8 = require('utf8');
API:
Encode:
utf8.encode(string)
Encodes any given JavaScript string (string) as UTF-8, and returns the UTF-8-encoded version of the string. It throws an error if the input string contains a non-scalar value, i.e. a lone surrogate. (If you need to be able to encode non-scalar values as well, use WTF-8 instead.)
// U+00A9 COPYRIGHT SIGN; see http://codepoints.net/U+00A9
utf8.encode('\xA9');
// ? '\xC2\xA9'
// U+10001 LINEAR B SYLLABLE B038 E; see http://codepoints.net/U+10001
utf8.encode('\uD800\uDC01');
// ? '\xF0\x90\x80\x81'
Decode:
utf8.decode(byteString)
Decodes any given UTF-8-encoded string (byteString) as UTF-8, and returns the UTF-8-decoded version of the string. It throws an error when malformed UTF-8 is detected. (If you need to be able to decode encoded non-scalar values as well, use WTF-8 instead.)
utf8.decode('\xC2\xA9');
// ? '\xA9'
utf8.decode('\xF0\x90\x80\x81');
// ? '\uD800\uDC01'
// ? U+10001 LINEAR B SYLLABLE B038 E
What is the value range? Is it 0 through 10? If so, then try:
SELECT REPLICATE('0',2-LEN(@t)) + CAST(@t AS VARCHAR)
That handles 0 through 9 as well as 10 through 99.
Now, tinyint can go up to the value of 255. If you want to handle > 99 through 255, then try this solution:
declare @t TINYINT
set @t =233
SELECT ISNULL(REPLICATE('0',2-LEN(@t)),'') + CAST(@t AS VARCHAR)
To understand the solution, the expression to the left of the + calculates the number of zeros to prefix to the string.
In case of the value 3, the length is 1. 2 - 1 is 1. REPLICATE Adds one zero. In case of the value 10, the length is 2. 2 - 2 is 0. REPLICATE Adds nothing. In the case of the value 100, the length is -1 which produces a NULL. However, the null value is handled and set to an empty string.
Now if you decide that because tinyint can contain up to 255 and you want your formatting as three characters, just change the 2-LEN to 3-LEN in the left expression and you're set.
The issue is most likely you will need to use an auto loader that will take the name of the class (break by '\' in this case) and map it to a directory structure.
You can check out this article on the autoloading functionality of PHP. There are many implementations of this type of functionality in frameworks already.
I've actually implemented one before. Here's a link.
Just my two cents, Silas Ray is on the right track, however I felt like adding an example. ;-)
Python is a type-unsafe language and thus you'll always have to trust the users of your code to use the code like a reasonable (sensible) person.
Per PEP 8:
Use one leading underscore only for non-public methods and instance variables.
To have a 'read-only' property in a class you can make use of the @property
decoration, you'll need to inherit from object
when you do so to make use of the new-style classes.
Example:
>>> class A(object):
... def __init__(self, a):
... self._a = a
...
... @property
... def a(self):
... return self._a
...
>>> a = A('test')
>>> a.a
'test'
>>> a.a = 'pleh'

This is bcrypt:
Generate a random salt. A "cost" factor has been pre-configured. Collect a password.
Derive an encryption key from the password using the salt and cost factor. Use it to encrypt a well-known string. Store the cost, salt, and cipher text. Because these three elements have a known length, it's easy to concatenate them and store them in a single field, yet be able to split them apart later.
When someone tries to authenticate, retrieve the stored cost and salt. Derive a key from the input password, cost and salt. Encrypt the same well-known string. If the generated cipher text matches the stored cipher text, the password is a match.
Bcrypt operates in a very similar manner to more traditional schemes based on algorithms like PBKDF2. The main difference is its use of a derived key to encrypt known plain text; other schemes (reasonably) assume the key derivation function is irreversible, and store the derived key directly.
Stored in the database, a bcrypt
"hash" might look something like this:
$2a$10$vI8aWBnW3fID.ZQ4/zo1G.q1lRps.9cGLcZEiGDMVr5yUP1KUOYTa
This is actually three fields, delimited by "$":
2a
identifies the bcrypt
algorithm version that was used.10
is the cost factor; 210 iterations of the key derivation function are used (which is not enough, by the way. I'd recommend a cost of 12 or more.)vI8aWBnW3fID.ZQ4/zo1G.q1lRps.9cGLcZEiGDMVr5yUP1KUOYTa
is the salt and the cipher text, concatenated and encoded in a modified Base-64. The first 22 characters decode to a 16-byte value for the salt. The remaining characters are cipher text to be compared for authentication.This example is taken from the documentation for Coda Hale's ruby implementation.
It appears that SSRS has an issue(at leastin version 2008) - I'm studying this website that explains it
Where it says if you have two columns(from 2 diff. tables) with the same name, then it'll cause that problem.
From source:
SELECT a.Field1, a.Field2, a.Field3, b.Field1, b.field99 FROM TableA a JOIN TableB b on a.Field1 = b.Field1
SQL handled it just fine, since I had prefixed each with an alias (table) name. But SSRS uses only the column name as the key, not table + column, so it was choking.
The fix was easy, either rename the second column, i.e. b.Field1 AS Field01 or just omit the field all together, which is what I did.
Single quotation marks won't do in that case. You have to add quotation marks around each path and also enclose the whole command in quotation marks:
cmd /C ""C:\Program Files (x86)\WinRar\Rar.exe" a "D:\Hello 2\File.rar" "D:\Hello 2\*.*""

You need to add a css rule that removes the after content (through a class)..
An update due to some valid comments.
The more correct way to completely remove/disable the :after
rule is to use
p.no-after:after{content:none;}
Original answer
You need to add a css rule that removes the after content (through a class)..
p.no-after:after{content:"";}
and add that class to your p
when you want to with this line
$('p').addClass('no-after'); // replace the p selector with what you need...

The [new-ish at the time of writing in 2017] Fetch API is intended to make GET requests easy, but it is able to POST as well.
let data = {element: "barium"};
fetch("/post/data/here", {

body: JSON.stringify(data)
}).then(res => {
console.log("Request complete! response:", res);
});
If you are as lazy as me (or just prefer a shortcut/helper):
window.post = function(url, data) {
return fetch(url, {method: "POST", body: JSON.stringify(data)});
}
// ...
post("post/data/here", {element: "osmium"});

According to the Apple doc below, device token can not be decoded. So, I think the best thing to do is just leave it be.
Security Architecture
A device token is an opaque NSData instance that contains a unique identifier assigned by Apple to a specific app on a specific device. Only APNs can decode and read the contents of a device token. Each app instance receives its unique device token when it registers with APNs, and must then forward the token to its provider, as described in Configuring Remote Notification Support. The provider must include the device token in each push notification request that targets the associated device; APNs uses the device token to ensure the notification is delivered only to the unique app-device combination for which it is intended.
shift
can be used in places where you want to get the first element (index=0
) of an array and chain with other array methods.
example:
const comps = [{}, {}, {}]
const specComp = comps
.map(fn1)
.filter(fn2)
.shift()
Remember shift
mutates the array, which is very different from accessing via an indexer.
At this moment, 2020-10-17, if you select a text element and hit CTRL+SHIFT+ALT+M it will highlight every instance within the code chunk.
Just create another class and add along with the bootstrap container
class. You can also use container-fluid
though.
<div class="container full-width">
<div class="row">
....
</div>
</div>
The CSS part is pretty simple
* {
margin: 0;
padding: 0;
}
.full-width {
width: 100%;
min-width: 100%;
max-width: 100%;
}
Hope this helps, Thanks!

return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}
So you can use:
myvar = getURLParameter('myvar');
The following worked for me:
$("[id=attached_docs][value=123]")
More oin regards to question part 4 How do you e-mail that error to an email address? The error_log function has email destination too. http://php.net/manual/en/function.error-log.php
Agha, here I found an example that shows a usage. Send errors message via email using error_log()
error_log($this->_errorMsg, 1, ADMIN_MAIL, "Content-Type: text/html; charset=utf8\r\nFrom: ".MAIL_ERR_FROM."\r\nTo: ".ADMIN_MAIL);
extern tells the compiler to trust you that the memory for this variable is declared elsewhere, so it doesnt try to allocate/check memory.
Therefore, you can compile a file that has reference to an extern, but you can not link if that memory is not declared somewhere.
Useful for global variables and libraries, but dangerous because the linker does not type check.
Kindly find below one liner bash script command to find all broken symbolic links recursively in any linux based OS
a=$(find / -type l); for i in $(echo $a); do file $i ; done |grep -i broken 2> /dev/null

From a broken link:
Within an Aggregate there is an Aggregate Root. The Aggregate Root is the parent Entity to all other Entities and Value Objects within the Aggregate.
A Repository operates upon an Aggregate Root.

Any - boolean function that returns true when any of object in list satisfies condition set in function parameters. For example:
List<string> strings = LoadList();
boolean hasNonEmptyObject = strings.Any(s=>string.IsNullOrEmpty(s));
Where - function that returns list with all objects in list that satisfy condition set in function parameters. For example:
IEnumerable<string> nonEmptyStrings = strings.Where(s=> !string.IsNullOrEmpty(s));
Exists - basically the same as any but it's not generic - it's defined in List class, while Any is defined on IEnumerable interface.
In my case, the solution was to set serverTimezone parameter in Advanced settings to an appropriate value (CET for my time zone).
As I use IntelliJ, I use its Database module. While adding a new connection to the database and after adding all relevant parameters in tab General, there was an error on "Test Connection" button. Again, the solution is to set serverTimezone parameter in tab Advanced.
Use include_once
instead.
This error means that you have already included this file.
include_once(LIB.'/class.php');
MySQL documentation covers this topic.
Here is a synopsis. When using join
or inner join
, the on
condition is optional. This is different from the ANSI standard and different from almost any other database. The effect is a cross join
. Similarly, you can use an on
clause with cross join
, which also differs from standard SQL.
A cross join creates a Cartesian product -- that is, every possible combination of 1 row from the first table and 1 row from the second. The cross join for a table with three rows ('a', 'b', and 'c') and a table with four rows (say 1, 2, 3, 4) would have 12 rows.
In practice, if you want to do a cross join, then use cross join
:
from A cross join B
is much better than:
from A, B
and:
from A join B -- with no on clause
The on
clause is required for a right or left outer join, so the discussion is not relevant for them.
If you need to understand the different types of joins, then you need to do some studying on relational databases. Stackoverflow is not an appropriate place for that level of discussion.
Having php installed I use this way:
URL_ENCODED_DATA=`php -r "echo urlencode('$DATA');"`
I could not find a prohibition in writing, but by convention, the Windows hosts file closely follows the UNIX hosts file, and you cannot put wildcard hostname references into that file.
If you read the man page, it says:
DESCRIPTION
The hosts file contains information regarding the known hosts on the net-
work. For each host a single line should be present with the following
information:
Internet address
Official host name
Aliases
Although it does say,
Host names may contain any printable character other than a field delim-
iter, newline, or comment character.
that is not true from a practical level.
Basically, the code that looks at the /etc/hosts file does not support a wildcard entry.
The workaround is to create all the entries in advance, maybe use a script to put a couple hundred entries at once.
Personally, what I've done in the past is give them a common class id and used that to select them. It may not be ideal as they have a class specified that may not exist, but it makes the selection a hell of a lot easier. Just make sure you're unique in your classnames.
i.e. for the example above I'd use your selection by class. Better still would be to change the class name from bold to 'tcol1', so you don't get any accidental inclusions into the jQuery results. If bold does actually refer to a CSS class, you can always specify both in the class property - i.e. 'class="tcol1 bold"'.
In summary, if you can't select by Name, either use a complicated jQuery selector and accept any related performance hit or use Class selectors.
You can always limit the jQuery scope by including the table name i.e. $('#tableID > .bold')
That should restrict jQuery from searching the "world".
Its could still be classed as a complicated selector, but it quickly constrains any searching to within the table with the ID of '#tableID', so keeps the processing to a minimum.
An alternative of this if you're looking for more than 1 element within #table1 would be to look this up separately and then pass it to jQuery as this limits the scope, but saves a bit of processing to look it up each time.
var tbl = $('#tableID');
var boldElements = $('.bold',tbl);
var rows = $('tr',tbl);
if (rows.length) {
var row1 = rows[0];
var firstRowCells = $('td',row1);
}
$(document).ready(function(){
$("#HoursEntry").change(function(){
var HoursEntry = $(#HoursEntry option:selected).val();
if(HoursEntry == "")
{
$("#HoursEntry").html("Please select");
return false;
}
});
});
You can just create an Image
object and put the base64 as its src
, including the data:image...
part like this:
var image = new Image();
image.src = 'data:image/png;base64,iVBORw0K...';
document.body.appendChild(image);
It's what they call "Data URIs" and here's the compatibility table for inner peace.
Quick Fix: I have the same problem to start the MongoDB and it was
easily fixed by running the file mongod.exe
(C:\Program Files\MongoDB\Server\3.2\bin
) then run the file mongo.exe
(C:\Program Files\MongoDB\Server\3.2\bin
)..Problem fixed
Call the TreeView.OnAfterSelect()
protected method after you programatically select the node.
If changing size or after loading some data it is adding the scroll bar then you can try following, create class and apply this class.
.auto-scroll {
overflow-y: overlay;
overflow-x: overlay;
}
On CentOS, just run rm linkname
and it will ask to "remove symbolic link?". Type Y and Enter, the link will be gone and the directory be safe.
// I built my datatable first, and populated it, columns, rows and all. //Then, once the datatable is functional, do the following to bind it to the DGV. NOTE: the DGV's AutoGenerateColumns property must be 'true' for this example, or the "assigning" of column names from datatable to dgv will not work. I also "added" my datatable to a dataset previously, but I don't think that is necessary.
BindingSource SBind = new BindingSource();
SBind.DataSource = dtSourceData;

If you want to refer to names from the header rather than column numbers, you can use something like this:
fname <- "test.csv"
headset <- read.csv(fname, header = TRUE, nrows = 10)

classes[names(classes) %in% c("time")] <- "character"
dataset <- read.csv(fname, header = TRUE, colClasses = classes)

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.
inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024]; //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
System.out.println(read);

You need to enclose your <parent>
elements in a surrounding element as XML Documents can have only one root node:
<parents> <!-- I've added this tag -->
<parent>
<child>
Text
</child>
</parent>
<parent>
<child>
<grandchild>
Text
</grandchild>
<grandchild>
Text
</grandchild>
</child>
<child>
Text
</child>
</parent>
</parents> <!-- I've added this tag -->
As you're receiving this markup from somewhere else, rather than generating it yourself, you may have to do this yourself by treating the response as a string and wrapping it with appropriate tags, prior to attempting to parse it as XML.
So, you've a couple of choices:
<parent>
node) and process each as a distinct XML DocumentPython (at least the most common implementation of it) follows a pattern of compiling the original source to byte codes, then interpreting the byte codes on a virtual machine. This means (again, the most common implementation) is neither a pure interpreter nor a pure compiler.
The other side of this is, however, that the compilation process is mostly hidden -- the .pyc files are basically treated like a cache; they speed things up, but you normally don't have to be aware of them at all. It automatically invalidates and re-loads them (re-compiles the source code) when necessary based on file time/date stamps.
About the only time I've seen a problem with this was when a compiled bytecode file somehow got a timestamp well into the future, which meant it always looked newer than the source file. Since it looked newer, the source file was never recompiled, so no matter what changes you made, they were ignored...
One of the things that can bite you is if you are using .onmousedown
as your user interaction; when you do that, and then an attempt is immediately made to select a field, it won't happen, because the mouse is being held down on something else. So change to .onmouseup
and viola, now focus()
works, because the mouse is in an un-clicked state when the attempt to change focus is made.
Beware that in Mysql, the utf8
character set is only a subset of the real UTF8 character set. In order to save one byte of storage, the Mysql team decided to store only three bytes of a UTF8 characters instead of the full four-bytes. That means that some east asian language and emoji aren't fully supported. To make sure you can store all UTF8 characters, use the utf8mb4
data type, and utf8mb4_bin
or utf8mb4_general_ci
in Mysql.
Here's a simpler Python implementation of @varun-vohra answer:
def apportion_pcts(pcts, total):
proportions = [total * (pct / 100) for pct in pcts]
apportions = [math.floor(p) for p in proportions]
remainder = total - sum(apportions)
remainders = [(i, p - math.floor(p)) for (i, p) in enumerate(proportions)]
remainders.sort(key=operator.itemgetter(1), reverse=True)
for (i, _) in itertools.cycle(remainders):
if remainder == 0:
break
else:
apportions[i] += 1
remainder -= 1
return apportions
You need math
, itertools
, operator
.
Microsoft Azure offers a framework that makes it easy to perform this. http://azure.github.io/azure-mobile-services/iOS/v2/Classes/MSTable.html#//api/name/readWithQueryString:completion:
Another solution is to use a RangeValidator where you set Type="Integer"
like this:
<asp:RangeValidator runat="server"
id="valrNumberOfPreviousOwners"
ControlToValidate="txtNumberOfPreviousOwners"
Type="Integer"
MinimumValue="0"
MaximumValue="999"
CssClass="input-error"
ErrorMessage="Please enter a positive integer."
Display="Dynamic">
</asp:RangeValidator>
You can set reasonable values for the MinimumValue
and MaximumValue
attributes too.
Use ffmpeg + ffserver. It works!!! You can get a config file for ffserver from ffmpeg.org and accordingly set the values.
Java doesn't (yet) have a good built-in Time
class (it has one for JDBC queries, but that's not what you want).
One option would be use the JodaTime APIs and its LocalTime class.
Sticking with just the built-in Java APIs, you are stuck with java.util.Date. You can use a SimpleDateFormat to parse the time, then the Date
comparison functions to see if it is before or after some other time:
SimpleDateFormat parser = new SimpleDateFormat("HH:mm");
Date ten = parser.parse("10:00");
Date eighteen = parser.parse("18:00");
try {
Date userDate = parser.parse(someOtherDate);
if (userDate.after(ten) && userDate.before(eighteen)) {
...
}
} catch (ParseException e) {
// Invalid date was entered
}
Or you could just use some string manipulations, perhaps a regular expression to extract just the hour and the minute portions, convert them to numbers and do a numerical comparison:
Pattern p = Pattern.compile("(\d{2}):(\d{2})");
Matcher m = p.matcher(userString);
if (m.matches() ) {
String hourString = m.group(1);
String minuteString = m.group(2);
int hour = Integer.parseInt(hourString);
int minute = Integer.parseInt(minuteString);
if (hour >= 10 && hour <= 18) {
...
}
}
It really all depends on what you are trying to accomplish.

For implementing the timeout on the function, this stackoverflow thread has answers on that.
Coarse-grained and Fine-grained both think about optimizing a number of servicess. But the difference is in the level. I like to explain with an example, you will understand easily.
Fine-grained: For example, I have 100 services like findbyId, findbyCategry, findbyName...... so on. Instead of that many services why we can not provide find(id, category, name....so on). So this way we can reduce the services. This is just an example, but the goal is how to optimize the number of services.
Coarse-grained: For example, I have 100 clients, each client have their own set of 100 services. So I have to provide 100*100 total services. It is very much difficult. Instead of that what I do is, I identify all common services which apply to most of the clients as one service set and remaining separately. For example in 100 services 50 services are common. So I have to manage 100*50 + 50 only.
I've been told they are the same.
Actually they are documented in the same place under ruby-doc.org:
http://www.ruby-doc.org/core/classes/Array.html#M000249
- ary.collect {|item| block } ? new_ary
- ary.map {|item| block } ? new_ary
- ary.collect ? an_enumerator
- ary.map ? an_enumerator
Invokes block once for each element of self. Creates a new array containing the values returned by the block. See also Enumerable#collect.
If no block is given, an enumerator is returned instead.a = [ "a", "b", "c", "d" ] a.collect {|x| x + "!" } #=> ["a!", "b!", "c!", "d!"] a #=> ["a", "b", "c", "d"]
Python is a language: a set of rules that can be used to write programs. There are several implementaions of this language.
No matter what implementation you take, they do pretty much the same thing: take the text of your program and interpret it, executing its instructions. None of them compile your code into C or any other language.
CPython is the original implementation, written in C. (The "C" part in "CPython" refers to the language that was used to write Python interpreter itself.)
Jython is the same language (Python), but implemented using Java.
IronPython interpreter was written in C#.
There's also PyPy - a Python interpreter written in Python. Make your pick :)
Just in case if someone needs this for Xamarin in c#:

Here's my programmer's answer from a simliar thread
Semantics 101
First take a look at this code and think about what's wrong here...
class car {
int wheels = 4;
string engine;
}
car mybike = new car();
mybike.wheels = 2;
mybike.engine = null;
The problem, of course, is that a bike is not a car. The car class is an inappropriate class for the bike instance. The code is error-free, but is semantically incorrect. It reflects poorly on the programmer.
Semantics 102
Now apply this to document markup. If your document needs to present tabular data, then the appropriate tag would be <table>
. If you place navigation into a table however, then you're misusing the intended purpose of the <table>
element. In the second case, you're not presenting tabular data -- you're (mis)using the <table>
element to achieve a presentational goal.
Conclusion
Will visitors notice? No. Does your boss care? Maybe. Do we sometimes cut corners as programmers? Sure. But should we? No. Who benefits if you use semantic markup? You -- and your professional reputation. Now go and do the right thing.
It's not very clear what the problem is and what you are trying to accomplish from the code you posted, but I'll take a stab at it.
In general, I suggest calling a function on ng-click like so:
<a ng-click="navigateToPath()">click me</a>
obj.val1
& obj.val2
should be available on your controller's $scope, you dont need to pass those into a function from the markup.
then, in your controller:
$scope.navigateToPath = function(){
var path = '/somePath/' + $scope.obj.val1 + '/' + $scope.obj.val2; //dont need the '#'
$location.path(path)
}

I was hit by an unresponsive build and absolutely nothing would allow me to either kill or cancel the build. Even trying to end the task would trigger a user input window, saying that it could not be ended while the build is still going on (quite ironic because that was precisely the intention, to leave that broken state).
The build was taken care of by MSBuild, so the one way I found is to end its task. When forcing MSBuild.exe to end, VS will wake up and finally see the build as cancelled, allowing you to work again.
Hope this helps someone in the same situation.
The remainder of a division can be discovered using the operator %

In case you need both the quotient and the modulo, there's the builtin divmod
function:
>>> seconds= 137
>>> minutes, seconds= divmod(seconds, 60)
You can use properties:
Object.defineProperty MDN documentation
Example:
function def(varName, onChange) {
var _value;
Object.defineProperty(this, varName, {
get: function() {
return _value;
},
set: function(value) {
if (onChange)
onChange(_value, value);
_value = value;
}
});
return this[varName];
}
def('myVar', function (oldValue, newValue) {
alert('Old value: ' + oldValue + '\nNew value: ' + newValue);
});
myVar = 1; // alert: Old value: undefined | New value: 1
myVar = 2; // alert: Old value: 1 | New value: 2
Copying a file is a relatively straightforward operation as shown by the examples below, but you should instead use the shutil stdlib module for that.
def copyfileobj_example(source, dest, buffer_size=1024*1024):
"""
Copy a file from source to dest. source and dest
must be file-like objects, i.e. any object with a read or
write method, like for example StringIO.
"""
while True:
copy_buffer = source.read(buffer_size)
if not copy_buffer:
break
dest.write(copy_buffer)
If you want to copy by filename you could do something like this:
def copyfile_example(source, dest):
# Beware, this example does not handle any edge cases!
with open(source, 'rb') as src, open(dest, 'wb') as dst:
copyfileobj_example(src, dst)
You can use switch like this:
XML Layout
<RadioGroup
android:id="@+id/RG"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="@+id/R1"
android:layout_width="wrap_contnet"
android:layout_height="wrap_content"
android:text="R1" />
<RadioButton
android:id="@+id/R2"
android:layout_width="wrap_contnet"
android:layout_height="wrap_content"
android:text="R2" />
</RadioGroup>
And JAVA Activity
switch (RG.getCheckedRadioButtonId()) {
case R.id.R1:
regAuxiliar = ultimoRegistro;
case R.id.R2:
regAuxiliar = objRegistro;
default:
regAuxiliar = null; // none selected
}
You will also need to implement an onClick function with button or setOnCheckedChangeListener function to get required functionality.
Try this:
public class Team
{
public int TeamId { get; set;}
public string Name { get; set; }
public virtual ICollection<Match> HomeMatches { get; set; }
public virtual ICollection<Match> AwayMatches { get; set; }
}
public class Match
{
public int MatchId { get; set; }
public int HomeTeamId { get; set; }

Primary keys are mapped by default convention. Team must have two collection of matches. You can't have single collection referenced by two FKs. Match is mapped without cascading delete because it doesn't work in these self referencing many-to-many.
I'm not able to test this right now, but I would think you could use jQuery's preventDefault method.
All other answer are correct, but remember that if you cast double to int you will loss decimal value.. so 2.9 double become 2 int.
You can use Math.round(double)
function or simply do :
(int)(yourDoubleValue + 0.5d)
ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.
fileUpload = (e) => {
let data = e.target.files
if(e.target.files[0]!=null){
this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
}
}
here fileUpload is a different js file which accepts two params like this
export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);
return dispatch => {
axios.put(BaseUrl.RestUrl + "ur/url", formData)
.then(response => {
callback(response.data);
}).catch(error => {
console.log("***** "+error)
});
}
}
don't forget to bind method in the constructor. Let me know if you need more help in this.
you can also quote string
''+document.location+''.substring(2,3);
Update
This is mainly to query the container not to update as building images is the way to be done
I had the same issue so I created docker-run, a very simple command-line tool that runs inside a docker container to update packages in other running containers.
It uses docker-py to communicate with running docker containers and update packages or run any arbitrary single command
Examples:
docker run --rm -v /var/run/docker.sock:/tmp/docker.sock itech/docker-run exec
by default this will run date
command in all running containers and return results but you can issue any command e.g. docker-run exec "uname -a"
To update packages (currently only using apt-get):
docker run --rm -v /var/run/docker.sock:/tmp/docker.sock itech/docker-run update
You can create and alias and use it as a regular command line e.g.
alias docker-run='docker run --rm -v /var/run/docker.sock:/tmp/docker.sock itech/docker-run'
use this Reload page
success: function(data){
if(data.success == true){ // if true (1)
setTimeout(function(){// wait for 5 secs(2)
location.reload(); // then reload the page.(3)
}, 5000);
}
}
The value is null, you have to check why... (in addition to the implementation of the solutions proposed here)
Check the hardware Connections.
In the error message shown:
Error response from daemon: Cannot start container foo_1: \ exec: "grunt serve": executable file not found in $PATH
It is complaining that it cannot find the executable grunt serve
, not that it could not find the executable grunt
with the argument serve
. The most likely explanation for that specific error is running the command with the json syntax:
[ "grunt serve" ]
in something like your compose file. That's invalid since the json syntax requires you to split up each parameter that would normally be split by the shell on each space for you. E.g.:
[ "grunt", "serve" ]
The other possible way you can get both of those into a single parameter is if you were to quote them into a single arg in your docker run
command, e.g.
docker run your_image_name "grunt serve"
and in that case, you need to remove the quotes so it gets passed as separate args to the run command:
docker run your_image_name grunt serve
For others seeing this, the executable file not found
means that Linux does not see the binary you are trying to run inside your container with the default $PATH
value. That could mean lots of possible causes, here are a few:
Did you remember to include the binary inside your image? If you run a multi-stage image, make sure that binary install is run in the final stage. Run your image with an interactive shell and verify it exists:
docker run -it --rm your_image_name /bin/sh
Your path when shelling into the container may be modified for the interactive shell, particularly if you use bash, so you may need to specify the full path to the binary inside the container, or you may need to update the path in your Dockerfile with:
ENV PATH=$PATH:/custom/dir/bin
The binary may not have execute bits set on it, so you may need to make it executable. Do that with chmod:
RUN chmod 755 /custom/dir/bin/executable
If you run the image with a volume, that volume can overlay the directory where the executable exists in your image. Volumes do not merge with the image, they get mounted in the filesystem tree same as any other Linux filesystem mount. That means files from the parent filesystem at the mount point are no longer visible. (Note that named volumes are initialized by docker from the image content, but this only happens when the named volume is empty.) So the fix is to not mount volumes on top of paths where you have executables you want to run from the image.
What is row?
Either of these could be correct.
1) I assume that you capture your ajax response in a javascript variable 'row'. If that is the case, this would hold true.
var result=row.split('|');
alert(result[2]);
otherwise
2) Use this where $(row)
is a jQuery
object.
var result=$(row).val().split('|');
alert(result[2]);
[As mentioned in the other answer, you may have to use $(row).val()
or $(row).text()
or $(row).html()
etc. depending on what $(row) is.]
Just append a div
with that class to body
, then remove it when you're done:
// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);
// Remove it (later)
$(".modal-backdrop").remove();
Live Example:
$("input").click(function() {_x000D_
var bd = $('<div class="modal-backdrop"></div>');_x000D_
bd.appendTo(document.body);_x000D_
setTimeout(function() {_x000D_
bd.remove();_x000D_
}, 2000);_x000D_
});

The updated or deleted values are stored in DELETED. we can get it by the below method in trigger
Full example,
CREATE TRIGGER PRODUCT_UPDATE ON PRODUCTS
FOR UPDATE
AS
BEGIN
DECLARE @PRODUCT_NAME_OLD VARCHAR(100)
DECLARE @PRODUCT_NAME_NEW VARCHAR(100)
SELECT @PRODUCT_NAME_OLD = product_name from DELETED
SELECT @PRODUCT_NAME_NEW = product_name from INSERTED
END
Quoting an answer from Scott Ming, which works with workbook containing multiple sheets:
Here is a python script getsheets.py (mirror), you should install pandas
and xlrd
before you use it.
Run this:
pip3 install pandas xlrd # or `pip install pandas xlrd`
How does it works?
$ python3 getsheets.py -h
Usage: getsheets.py [OPTIONS] INPUTFILE
Convert a Excel file with multiple sheets to several file with one sheet.
Examples:
getsheets filename
getsheets filename -f csv
Options:
-f, --format [xlsx|csv] Default xlsx.
-h, --help Show this message and exit.
Convert to several xlsx:
$ python3 getsheets.py goods_temp.xlsx
Sheet.xlsx Done!
Sheet1.xlsx Done!
All Done!
Convert to several csv:
$ python3 getsheets.py goods_temp.xlsx -f csv
Sheet.csv Done!
Sheet1.csv Done!
All Done!
getsheets.py
:
# -*- coding: utf-8 -*-
import click
import os
import pandas as pd
def file_split(file):
s = file.split('.')
name = '.'.join(s[:-1]) # get directory name
return name
def getsheets(inputfile, fileformat):
name = file_split(inputfile)
try:
os.makedirs(name)
except:
pass
df1 = pd.ExcelFile(inputfile)
for x in df1.sheet_names:
print(x + '.' + fileformat, 'Done!')
df2 = pd.read_excel(inputfile, sheetname=x)
filename = os.path.join(name, x + '.' + fileformat)
if fileformat == 'csv':
df2.to_csv(filename, index=False)
else:
df2.to_excel(filename, index=False)
print('\nAll Done!')

I got the solution for your requirement.
I'm also getting the same error in my eclipse Luna.
Go to Windows option -> select preference.
Than Select General -> Network Connection.
Than select the Active Provider as Manual.
Then restart the tomcat and run. It will work.
Hope it will help you.
Simple answer
If you are behind a proxy server, please set the proxy for curl. The curl is not able to connect to server so it shows wrong version number. Set proxy by opening subl ~/.curlrc or use any other text editor. Then add the following line to file: proxy= proxyserver:proxyport For e.g. proxy = 10.8.0.1:8080
If you are not behind a proxy, make sure that the curlrc file does not contain the proxy settings.
Just supply literal values in the SELECT:
INSERT INTO TABLE1 (id, col_1, col_2, col_3)
SELECT id, 'data1', 'data2', 'data3'
FROM TABLE2
WHERE col_a = 'something';
A select list can contain any value expression:
But the expressions in the select list do not have to reference any columns in the table expression of the FROM clause; they can be constant arithmetic expressions, for instance.
And a string literal is certainly a value expression.
This work on all browser to get pasted value. And also to creating common method for all text box.
$("#textareaid").bind("paste", function(e){
var pastedData = e.target.value;
alert(pastedData);
} )
For the sake of completeness, isinstance will not work for type checking of a subtype that is not an instance. While that makes perfect sense, none of the answers (including the accepted one) covers it. Use issubclass for that.
>>> class a(list):
... pass
...
>>> isinstance(a, list)
False
>>> issubclass(a, list)
True
By setting the Visibility of all items in Menu, the appbar menu or overflow menu will be Hide automatically
Example
private Menu menu_change_language;
...
...
@Override
public boolean onCreateOptionsMenu(Menu menu) {
...
...
menu_change_language = menu;
menu_change_language.findItem(R.id.menu_change_language).setVisible(true);
return super.onCreateOptionsMenu(menu);
}
Before going to other fragment use bellow code:
if(menu_change_language != null){
menu_change_language.findItem(R.id.menu_change_language)
.setVisible(false);
}

It is possible to do manually, my tips are:
use eval
and/or exec
with encrypted strings
use [ord(i) for i in s]
/ ''.join(map(chr, [list of chars goes here]))
as simple encryption/decryption
use obscure variable names
make it unreadable
Don't write just 1 or True, write 1&True&0x00000001
;)
use different number systems
add confusing comments like "line 2" on line 10 or "it returns 0" on while loop.
use __builtins__
use getattr
and setattr
For Intellij IDEA Community 2019.1 you will need to follow these steps :

Use Validator.element()
:
Validates a single element, returns true if it is valid, false otherwise.
Here is the example shown in the API:
var validator = $( "#myform" ).validate();
validator.element( "#myselect" );
.valid()
validates the entire form, as others have pointed out. The API says:
Checks whether the selected form is valid or whether all selected elements are valid.
Twisted can help you with what you are doing, check out their documentation, there are plenty of examples. Also it is a mature product with a big developer/user community behind it.
None of these solutions worked for me. But I was able to get vertical centering by using <div class="form-row align-items-center">
for each form row, per the Bootstrap examples.
local constants:
const val NAME = "name"
Global constants:
object MyConstants{
val NAME = "name"
val ID = "_id"
var EMAIL = "email"
}
access MyConstants.NAME
Try the following.
string input = "someString";
string[] toSearchFor = GetSearchStrings();
var containsAll = toSearchFor.All(x => input.Contains(x));
One of the way is Using below sql queries

I took the liberty of modifying ConorLuddy's answer to address both 24 hour time and 12 hour time.
function minutesToHHMM (mins, twentyFour = false) {
let h = Math.floor(mins / 60);
let m = mins % 60;
m = m < 10 ? '0' + m : m;
if (twentyFour) {
h = h < 10 ? '0' + h : h;
return `${h}:${m}`;
} else {
let a = 'am';
if (h >= 12) a = 'pm';
if (h > 12) h = h - 12;
return `${h}:${m} ${a}`;
}
}
I like indent
as mentioned above, but most often I want to format only a small section of the file that I'm working on. Since indent
can take code from stdin, its really simple:
:!indent
.astyle
takes stdin too, so you can use the same trick there.

You're not working with strings. You're working with pointers.
var1
is a char pointer (const char*
). It is not a string. If it is null-terminated, then certain C functions will treat it as a string, but it is fundamentally just a pointer.
So when you compare it to a char array, the array decays to a pointer as well, and the compiler then tries to find an operator == (const char*, const char*)
.
Such an operator does exist. It takes two pointers and returns true
if they point to the same address. So the compiler invokes that, and your code breaks.
IF you want to do string comparisons, you have to tell the compiler that you want to deal with strings, not pointers.
The C way of doing this is to use the strcmp
function:
strcmp(var1, "dev");
This will return zero if the two strings are equal. (It will return a value greater than zero if the left-hand side is lexicographically greater than the right hand side, and a value less than zero otherwise.)
So to compare for equality you need to do one of these:
if (!strcmp(var1, "dev")){...}
if (strcmp(var1, "dev") == 0) {...}
However, C++ has a very useful string
class. If we use that your code becomes a fair bit simpler. Of course we could create strings from both arguments, but we only need to do it with one of them:
std::string var1 = getenv("myEnvVar");
if(var1 == "dev")
{
// do stuff
}
Now the compiler encounters a comparison between string and char pointer. It can handle that, because a char pointer can be implicitly converted to a string, yielding a string/string comparison. And those behave exactly as you'd expect.
You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.
When using storageClass
Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.
storageClass
-line from the PersistentVolumeClaimAt creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.
The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.
The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound
"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.
A PersistentVolume without StorageClass is considered to be static.
"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.
In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:
apiVersion: v1
kind: PersistentVolume
metadata:
name: ckan-pv-home
labels:
type: local
spec:
capacity:
storage: 100Mi
hostPath:
path: "/mnt/data/ckan"
The PersistentVolumeSpec allows us to define multiple attributes.
I chose a hostPath
volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.
Just Do a "npm audit" on your project directory and then go to your project package.json file. In the package.json file you will find all the versions and the package names.This should work irrespective of the OS.
Have you tried this:
function doSomething() {
if ($(this).hasClass('clickedTag')){
// code here
} else {
// and here
}
}
$('.tag1, .tag2').click(doSomething);
How about a workaround?
In my case I took the value of the textarea in a jQuery variable, and changed all "<p> "
to <p class="clear">
and clear class to have certain height and margin, as the following example:
jQuery
tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p> /g, '<p class="clear">');
the val is then saved to the database with the new val.
CSS
p.clear{height: 2px; margin-bottom: 3px;}
You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.
Hope that helps!
Building on the answers of prufrofro and Frank van Puffelen here, I put together this setup that doesn't prevent scraping, but can make it slightly harder to use your API key.
Warning: To get your data, even with this method, one can for example simply open the JS console in Chrome and type:
firebase.database().ref("/get/all/the/data").once("value", function (data) {
console.log(data.val());
});
Only the database security rules can protect your data.
Nevertheless, I restricted my production API key use to my domain name like this:
projectname.firebaseapp.com/*
)Now the app will only work on this specific domain name. So I created another API Key that will be private for localhost developement.
By default, as mentioned by Emmanuel Campos, Firebase only whitelists localhost
and your Firebase hosting domain.
In order to make sure I don't publish the wrong API key by mistake, I use one of the following methods to automatically use the more restricted one in production.
Setup for Create-React-App
In /env.development
:
REACT_APP_API_KEY=###dev-key###
In /env.production
:
REACT_APP_API_KEY=###public-key###
In /src/index.js
const firebaseConfig = {
apiKey: process.env.REACT_APP_API_KEY,
// ...
};
Your code is fine. There's no problem with returning Strings
in this manner.
In Java, a String
is a reference to an immutable object. This, coupled with garbage collection, takes care of much of the potential complexity: you can simply pass a String
around without worrying that it would disapper on you, or that someone somewhere would modify it.
If you don't mind me making a couple of stylistic suggestions, I'd modify the code like so:
public String time_to_string(long t) // time in milliseconds
{
if (t < 0)
{
return "-";
}
else
{
int secs = (int)(t/1000);
int mins = secs/60;
secs = secs - (mins * 60);
return String.format("%d:%02d", mins, secs);
}
}
As you can see, I've pushed the variable declarations as far down as I could (this is the preferred style in C++ and Java). I've also eliminated ans
and have replaced the mix of string concatenation and String.format()
with a single call to String.format()
.
I think you are getting confused about what the a:active
CSS selector does. This will only change the colour of your link when you click it (and only for the duration of the click i.e. how long your mouse button stays down). What you need to do is introduce a new class e.g. .selected
into your CSS and when you select a link, update the selected menu item with new class e.g.
<div class="menuBar">
<ul>
<li class="selected"><a href="index.php">HOME</a></li>
<li><a href="two.php">PORTFOLIO</a></li>
....
</ul>
</div>
// specific CSS for your menu
div.menuBar li.selected a { color: #FF0000; }
// more general CSS
li.selected a { color: #FF0000; }
You will need to update your template page to take in a selectedPage
parameter.
I had 20.8 GB in the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder (6 android images: - android-10 - android-15 - android-21 - android-23 - android-25 - android-26 ).
I have compressed the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder.
Now it takes only 4.65 GB.
I did not encountered any problem up to now...
Compression seems to vary from 2/3 to 6, sometimes much more:
You can have separate configuration file, but you'll have to read it "manually", the ConfigurationManager.AppSettings["key"]
will read only the config of the running assembly.
Assuming you're using Visual Studio as your IDE, you can right click the desired project ? Add ? New item ? Application Configuration File
This will add App.config
to the project folder, put your settings in there under <appSettings>
section. In case you're not using Visual Studio and adding the file manually, make sure to give it such name: DllName.dll.config, otherwise the below code won't work properly.
Now to read from this file have such function:
string GetAppSetting(Configuration config, string key)
{
KeyValueConfigurationElement element = config.AppSettings.Settings[key];
if (element != null)
{
string value = element.Value;
if (!string.IsNullOrEmpty(value))
return value;
}
return string.Empty;
}
And to use it:
Configuration config = null;
string exeConfigPath = this.GetType().Assembly.Location;
try
{
config = ConfigurationManager.OpenExeConfiguration(exeConfigPath);
}
catch (Exception ex)
{
//handle errror here.. means DLL has no sattelite configuration file.
}
if (config != null)
{
string myValue = GetAppSetting(config, "myKey");
...
}
You'll also have to add reference to System.Configuration namespace in order to have the ConfigurationManager class available.
When building the project, in addition to the DLL you'll have DllName.dll.config
file as well, that's the file you have to publish with the DLL itself.
The above is basic sample code, for those interested in a full scale example, please refer to this other answer.
echo strtotime("-1 month");
That will output the timestamp for last month exactly. You don't need to reset anything afterwards. If you want it in an English format after that, you can use date() to format the timestamp, ie:
echo date("Y-m-d H:i:s",strtotime("-1 month"));
You can use []
to extract values from a QueryDict
object like you would any ordinary dictionary.

request.POST['section'] # => [39]

Fixes this issue on windows like a charm.
Autossh is best option - checking process is not working in all cases (e.g. zombie process, network related problems)
example:
autossh -M 2323 -c arcfour -f -N -L 8088:localhost:80 host2
You could spare yourself the transformations, you could use CSS3 Transitions to flip <div>

You can reference Microsoft.VisualBasic.dll
.
Then using the code below.
Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");
Alternatively, by adding a using
directive allowing for a shorter syntax in your code (which I'd personally prefer).
using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");
Or you can do what Pranay Rana suggests, that's what I would've done too...
In Android Studio:
Build
Build APK(s)
Wait and go to the location shown in a pop-up window. On right bottom side
//Date
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .medium
let dateString = "Current date is: \(dateFormatter.string(from: Date() as Date))"
labelfordate.text = String(dateString)
//Time
let timeFormatter = DateFormatter()
timeFormatter.timeStyle = .medium
let timeString = "Current time is: \(timeFormatter.string(from: Date() as Date))"
labelfortime.text = String(timeString)
override func viewDidLoad() {
super.viewDidLoad()
timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(DateAndTime.action), userInfo: nil, repeats: true)
}
func action()
{
//Date
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .medium
let dateString = "Current date is: \(dateFormatter.string(from: Date() as Date))"
labelfordate.text = String(dateString)
//Time
let timeFormatter = DateFormatter()
timeFormatter.timeStyle = .medium
let timeString = "Current time is: \(timeFormatter.string(from: Date() as Date))"
labelfortime.text = String(timeString)
}
Note: DateAndTime in the Timer code is the Class name.
The problem is that you call remove
on the root of your Firebase:
ref = new Firebase("myfirebase.com")
ref.remove();
This will remove the entire Firebase through the API.
You'll typically want to remove specific child nodes under it though, which you do with:
ref.child(key).remove();
use target="_blank"
<a target='_blank' href="http://www.starfall.com/">Starfall</a>
Another way to do this is to use the numpy matrix
class (rather than a numpy array) and the I
attribute. For example:
>>> m = np.matrix([[2,3],[4,5]])
>>> m.I
matrix([[-2.5, 1.5],
[ 2. , -1. ]])
Localization support in legacy browsers is poor. Originally, this was due to phrases in the ECMAScript
language spec that look like this:
Number.prototype.toLocaleString()
Produces a string value that represents the value of the Number formatted according to the conventions of the host environment’s current locale. This function is implementation-dependent, and it is permissible, but not encouraged, for it to return the same thing as toString.
Every localization method defined in the spec is defined as "implementation-dependent", which results in a lot of inconsistencies. In this instance, Chrome Opera and Safari would return the same thing as .toString()
. Firefox and IE will return locale formatted strings, and IE even includes a thousand separator (perfect for currency strings). Chrome was recently updated to return a thousands-separated string, though with no fixed decimal.
For modern environments, the ECMAScript Internationalization API spec, a new standard that complements the ECMAScript Language spec, provides much better support for string comparison, number formatting, and the date and time formatting; it also fixes the corresponding functions in the Language Spec. An introduction can be found here. Implementations are available in:
There is also a compatibility implementation, Intl.js, which will provide the API in environments where it doesn't already exist.
Determining the user's preferred language remains a problem since there's no specification for obtaining the current language. Each browser implements a method to obtain a language string, but this could be based on the user's operating system language or just the language of the browser:
// navigator.userLanguage for IE, navigator.language for others
var lang = navigator.language || navigator.userLanguage;
A good workaround for this is to dump the Accept-Language header from the server to the client. If formatted as a JavaScript, it can be passed to the Internationalization API constructors, which will automatically pick the best (or first-supported) locale.
In short, you have to put in a lot of the work yourself, or use a framework/library, because you cannot rely on the browser to do it for you.
Various libraries and plugins for localization:
Feel free to add/edit.
You can write a simple gradle script to print your GRADLE_HOME
directory.
task getHomeDir {
doLast {
println gradle.gradleHomeDir
}
}
and name it build.gradle
.
Then run it with:
gradle getHomeDir
If you installed with homebrew, use brew info gradle
to find the base path (i.e. /usr/local/Cellar/gradle/1.10/
), and just append libexec
.
The same task in Kotlin in case you use build.gradle.kts
:
tasks.register("getHomeDir") {
println("Gradle home dir: ${gradle.gradleHomeDir}")
}
// replace
return <p>hello</p>;
// with
return <p>{JSON.stringify(movies)}</p>;
Now you should see, that your code actually does work. What does not work is the console.log(movies)
. This is because movies
points to the old state. If you move your console.log(movies)
outside of useEffect
, right above the return, you will see the updated movies object.
Here is another way...
It adds "others" to the enum definition of the column "rtipo" of the table "firmas".
set @new_enum = 'others';
set @table_name = 'firmas';
set @column_name = 'rtipo';
select column_type into @tmp from information_schema.columns
where table_name = @table_name and column_name=@column_name;
set @tmp = insert(@tmp, instr(@tmp,')'), 0, concat(',\'', @new_enum, '\'') );
set @tmp = concat('alter table ', @table_name, ' modify ', @column_name, ' ', @tmp);
prepare stmt from @tmp;
execute stmt;
deallocate prepare stmt;
var r = confirm('Want to delete ?');
if (r == true) {
$('#admin-category-destroy').submit();
}
If (theChar >= '0' && theChar <='9')
it's a digit. You get the idea.
NaN is the only value in JS which is not equals to itself so we can use this information in our favour
const x = NaN;
let y = x!=x && 0;
y = Number.isNaN(x) && 0
We can also use Number.isNaN instead of isNaN function as latter coerces its argument to number
isNaN('string') // true which is incorrect because 'string'=='string'
Number.isNaN('string') // false
Lets say above one is your original dataframe and you want to add a new column 'old'
If age greater than 50 then we consider as older=yes otherwise False
step 1: Get the indexes of rows whose age greater than 50
row_indexes=df[df['age']>=50].index
step 2:
Using .loc we can assign a new value to column
df.loc[row_indexes,'elderly']="yes"
same for age below less than 50
row_indexes=df[df['age']<50].index
df[row_indexes,'elderly']="no"
The code that you have is correct. To get a variable from another class you need to create an instance of the class if the variable is not static, and just call the explicit method to get access to that variable. If you put get and set method like the above is the same of declaring that variable public.
Put the method setNum private and inside the getNum assign the value that you want, you will have "get" access to the variable in that case
Excerpted from Josh Stodola's Setting keyboard caret Position in a Textbox or TextArea with Javascript
A generic function that will allow you to insert the caret at any position of a textbox or textarea that you wish:
function setCaretPosition(elemId, caretPos) {
var elem = document.getElementById(elemId);
if(elem != null) {
if(elem.createTextRange) {
var range = elem.createTextRange();
range.move('character', caretPos);
range.select();
}
else {
if(elem.selectionStart) {
elem.focus();
elem.setSelectionRange(caretPos, caretPos);
}
else
elem.focus();
}
}
}
The first expected parameter is the ID of the element you wish to insert the keyboard caret on. If the element is unable to be found, nothing will happen (obviously). The second parameter is the caret positon index. Zero will put the keyboard caret at the beginning. If you pass a number larger than the number of characters in the elements value, it will put the keyboard caret at the end.
Tested on IE6 and up, Firefox 2, Opera 8, Netscape 9, SeaMonkey, and Safari. Unfortunately on Safari it does not work in combination with the onfocus event).
An example of using the above function to force the keyboard caret to jump to the end of all textareas on the page when they receive focus:
function addLoadEvent(func) {
if(typeof window.onload != 'function') {
window.onload = func;
}
else {
if(func) {
var oldLoad = window.onload;
window.onload = function() {
if(oldLoad)
oldLoad();
func();
}
}
}
}
// The setCaretPosition function belongs right here!
function setTextAreasOnFocus() {
/***
* This function will force the keyboard caret to be positioned
* at the end of all textareas when they receive focus.
*/
var textAreas = document.getElementsByTagName('textarea');
for(var i = 0; i < textAreas.length; i++) {
textAreas[i].onfocus = function() {
setCaretPosition(this.id, this.value.length);
}
}
textAreas = null;
}
addLoadEvent(setTextAreasOnFocus);
JObject.ContainsKey(string propertyName)

Yes, you can by using DBlink (postgresql only) and DBI-Link (allows foreign cross database queriers) and TDS_LInk which allows queries to be run against MS SQL server.
I have used DB-Link and TDS-link before with great success.
It looks you are almost there. Try:
if(error == true){
// Your application has indicated there's an error
window.setTimeout(function(){
// Move to a new location or you can do something else
window.location.href = "https://www.google.co.in";
}, 5000);
}
You use the word initialize so it's unclear if this is one-time assignment or can happen multiple times.
If you just need a one time initialization, you can put it in the constructor and use the two iterator vector constructor:
Foo::Foo(double* w, int len) : w_(w, w + len) { }
Otherwise use assign as previously suggested:
void set_data(double* w, int len)
{
w_.assign(w, w + len);
}
<form action="portfolio.html">
<button type="link" class="btn btn-primary btn-lg">View Work</button>
</form>
I just figured this out, and it links perfectly to another page without having my default link settings over ride my button classes! :)
I've had to face this issue and also tried to solve it from different perspectives. Finally I found a solution by using a single flag to check if an error happened.
... extends WebViewClient {
boolean error;
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
showLoading(true);
super.onPageStarted(view, url, favicon);
error = false; // IMPORTANT
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
if(!error) {
Observable.timer(100, TimeUnit.MICROSECONDS, AndroidSchedulers.mainThread())
.subscribe((data) -> view.setVisibility(View.VISIBLE) );
}
showLoading(false);
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
view.stopLoading();
view.setVisibility(View.INVISIBLE)
error = true;
// Handle the error
}
@Override
@TargetApi(android.os.Build.VERSION_CODES.M)
public void onReceivedError(WebView view,
WebResourceRequest request,
WebResourceError error) {
this.onReceivedError(view, error.getErrorCode(),
error.getDescription().toString(),
request.getUrl().toString());
}
}
This way I hide the page every time there's an error and show it when the page has loaded again properly.
Also added a small delay in case.
I avoided the solution of loading an empty page as it does not allow you to do webview.reload() later on due to it adds that new page in the navigation history.
I use LuaSocket to get more precision.
require "socket"
print("Milliseconds: " .. socket.gettime()*1000)
This adds a dependency of course, but works fine for personal use (in benchmarking scripts for example).
Try to add the path to tnsnames.ora to the config file:

<configuration>
<oracle.manageddataaccess.client>
<version number="4.112.3.60">

Deleting node modules folder worked for me.
npm install
.There are two ways to do the same instruction, that is, an empty string. The first way is to allocate an empty string on static memory:
char* my_variable = "";
or, if you want to be explicit:
char my_variable = '\0';
The way posted above is only for a character. And, the second way:
#include <string.h>
char* my_variable = strdup("");
Don't forget to use free() with this one because strdup() use malloc inside.
A simple one would be
\d{4}-\d{2}-\d{2}
but this does not restrict month to 1-12 and days from 1 to 31.
There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.
The concept of number/length/dimensionality doesn't really make sense for an Object, and needing it suggests you really want an Array to me.
Edit: Pointed out to me that you want an O(1) for this. To the best of my knowledge no such way exists I'm afraid.
You can cast datetime to time
select CAST(GETDATE() as time)
If you want a hh:mm format
select cast(CAST(GETDATE() as time) as varchar(5))
A combination of line styles, markers, and qualitative colors from matplotlib
:
import itertools
import matplotlib as mpl
import matplotlib.pyplot as plt
N = 8*4+10
l_styles = ['-','--','-.',':']
m_styles = ['','.','o','^','*']
colormap = mpl.cm.Dark2.colors # Qualitative colormap
for i,(marker,linestyle,color) in zip(range(N),itertools.product(m_styles,l_styles, colormap)):
plt.plot([0,1,2],[0,2*i,2*i], color=color, linestyle=linestyle,marker=marker,label=i)
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=4);
UPDATE: Supporting not only ListedColormap
, but also LinearSegmentedColormap
import itertools
import matplotlib.pyplot as plt
Ncolors = 8
#colormap = plt.cm.Dark2# ListedColormap
colormap = plt.cm.viridis# LinearSegmentedColormap
Ncolors = min(colormap.N,Ncolors)
mapcolors = [colormap(int(x*colormap.N/Ncolors)) for x in range(Ncolors)]
N = Ncolors*4+10
l_styles = ['-','--','-.',':']
m_styles = ['','.','o','^','*']
fig,ax = plt.subplots(gridspec_kw=dict(right=0.6))
for i,(marker,linestyle,color) in zip(range(N),itertools.product(m_styles,l_styles, mapcolors)):
ax.plot([0,1,2],[0,2*i,2*i], color=color, linestyle=linestyle,marker=marker,label=i)
ax.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=3,prop={'size': 8})
If it were me, I'd put the EXE file in the root directory (C:) and see if it works like that. If so, it's probably the (already mentioned) spaces in the directory name. If not, it may be some environment variables.
Also, try to check you stderr (using an earlier answer by int3):
import subprocess
process = subprocess.Popen(["C:/Documents and Settings/flow_model/flow.exe"], \
stderr = subprocess.PIPE)
if process.stderr:
print process.stderr.readlines()
The code might not be entirely correct as I usually don't use Popen or Windows, but should give the idea. It might well be that the error message is on the error stream.
My assumption that this exception usually occurs when Tomcat is improperly closed and still holding the ports. Usually it is enough to kill any process listening to 1099 port. For Window 10:
netstat -aon | find "1099"
taskkill /F /PID $processId
to identify hive version on a EC2 instance use
hive --version
Like T.J. wrote: the order is defined (at least it's sequential when your browser is about to execute any JavaScript, even if it may download the scripts in parallel somehow). However, as apparently you're having trouble, maybe you're using third-party JavaScript libraries that yield some 404 Not Found or timeout? If so, then read Best way to use Google’s hosted jQuery, but fall back to my hosted library on Google fail.
Always keep in mind that 'size' is variable if not explicitly specified so if you declare
int i = 10;
On some systems it may result in 16-bit integer by compiler and on some others it may result in 32-bit integer (or 64-bit integer on newer systems).
In embedded environments this may end up in weird results (especially while handling memory mapped I/O or may be consider a simple array situation), so it is highly recommended to specify fixed size variables. In legacy systems you may come across
typedef short INT16;
typedef int INT32;
typedef long INT64;
Starting from C99, the designers added stdint.h header file that essentially leverages similar typedefs.
On a windows based system, you may see entries in stdin.h header file as
typedef signed char int8_t;
typedef signed short int16_t;
typedef signed int int32_t;
typedef unsigned char uint8_t;
There is quite more to that like minimum width integer or exact width integer types, I think it is not a bad thing to explore stdint.h for a better understanding.
Java conveniently has the instanceof
operator (JLS 15.20.2) to test if a given object is of a given type.
if (x instanceof List<?>) {
List<?> list = (List<?>) x;
// do something with list
} else if (x instanceof Collection<?>) {
Collection<?> col = (Collection<?>) x;
// do something with col
}
One thing should be mentioned here: it's important in these kinds of constructs to check in the right order. You will find that if you had swapped the order of the check in the above snippet, the code will still compile, but it will no longer work. That is the following code doesn't work:
// DOESN'T WORK! Wrong order!
if (x instanceof Collection<?>) {
Collection<?> col = (Collection<?>) x;
// do something with col
} else if (x instanceof List<?>) { // this will never be reached!
List<?> list = (List<?>) x;
// do something with list
}
The problem is that a List<?>
is-a Collection<?>
, so it will pass the first test, and the else
means that it will never reach the second test. You have to test from the most specific to the most general type.
If you want all groups known to the system, I would recommend using getent group
instead of parsing /etc/group
:
getent group
The reason is that on networked systems, groups may not only read from /etc/group
file, but also obtained through LDAP or Yellow Pages (the list of known groups comes from the local group file plus groups received via LDAP or YP in these cases).
If you want just the group names you can use:
getent group | cut -d: -f1
There is a possibility not to use extra variables
String s = "HelloSuresh";
s = s.replace("Hello","");
System.out.println(s);
I believe you can use the append
method
bigdata = data1.append(data2, ignore_index=True)
to keep their indexes just dont use the ignore_index
keyword ...
You can do (jQuery 1.6 onwards):
$('#idCheckbox').prop('checked', true);
$('#idCheckbox').prop('checked', false);
to remove you can also use:
$('#idCheckbox').removeProp('checked');
with jQuery < 1.6 you must do
$('#idCheckbox').attr('checked', true);
$('#idCheckbox').removeAttr('checked');
Use a comma ","
eg:
UPDATE my_table SET rowOneValue = rowOneValue + 1, rowTwoValue = rowTwoValue + ( (rowTwoValue / (rowTwoValue) ) + ?) * (v + 1) WHERE value = ?
I can suggest using WITH
like this:
DECLARE @Delim char(1) = ',';
SET @Ids = @Ids + @Delim;
WITH CTE(i, ls, id) AS (
SELECT 1, CHARINDEX(@Delim, @Ids, 1), SUBSTRING(@Ids, 1, CHARINDEX(@Delim, @Ids, 1) - 1)
UNION ALL
SELECT i + 1, CHARINDEX(@Delim, @Ids, ls + 1), SUBSTRING(@Ids, ls + 1, CHARINDEX(@Delim, @Ids, ls + 1) - CHARINDEX(@Delim, @Ids, ls) - 1)
FROM CTE
WHERE CHARINDEX(@Delim, @Ids, ls + 1) > 1
)
SELECT t.*
FROM yourTable t
INNER JOIN
CTE c
ON t.id = c.id;
using logback 1.1.3 I had to do the following (Scala code):

val root: Logger = LoggerFactory.getLogger(org.slf4j.Logger.ROOT_LOGGER_NAME).asInstanceOf[Logger]
torek's answer is probably perfect, but I just wanted for the record to mention another case which is different than the one described in the original question but the same error may appear (as it may help others with similar problem):
I have created an empty (new) repo using git init --bare
on one of my servers. Then I have git clone
d it to a local workspace on my PC.
After committing a single version on the local repo I got that error after calling git status
.
Following torek's answer, I understand that what happened is that the first commit on local working directory repo created "master" branch. But on the remote repo (on the server) there was never anything, so there was not even a "master" (remotes/origin/master) branch.
After running git push origin master
from local repo the remote repo finally had a master branch. This stopped the error from appearing.
So to conclude - one may get such an error for a fresh new remote repo with zero commits since it has no branch, including "master".
Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

I seemed to solve this by manually removing the unicorn gem via bundler ("sudo bundler exec gem uninstall unicorn"), then rebundling ("sudo bundle install").
Not sure why it happened though, although the above fix does seem to work.
You can use this Firefox addon to download all files in HTTP Directory.
https://addons.mozilla.org/en-US/firefox/addon/http-directory-downloader/
In my case I have a group of files which needs to be renamed before I can work with them. Each file has its own role in group and has its own pattern.
As result I have a list of rename commands like this:
f=`ls *canctn[0-9]*` ; mv $f CNLC.$f
f=`ls *acustb[0-9]*` ; mv $f CATB.$f
f=`ls *accusgtb[0-9]*` ; mv $f CATB.$f
f=`ls *acus[0-9]*` ; mv $f CAUS.$f
Try this also :
f=MyFileName; mv $f {pref1,pref2}$f{suf1,suf2}
This will produce all combinations with prefixes and suffixes:
pref1.MyFileName.suf1
...
pref2.MyFileName.suf2
Another way to solve same problem is to create mapping array and add corespondent prefix for each file type as shown below:
#!/bin/bash
unset masks
typeset -A masks
masks[ip[0-9]]=ip
masks[iaf_usg[0-9]]=ip_usg
masks[ipusg[0-9]]=ip_usg
...
for fileMask in ${!masks[*]};
do
registryEntry="${masks[$fileMask]}";
fileName=*${fileMask}*
[ -e ${fileName} ] && mv ${fileName} ${registryEntry}.${fileName}
done
In ES6, you could write something like:
let myVar = 'something';
let nameObject = {myVar};
let getVarNameFromObject = (nameObject) => {
for(let varName in nameObject) {
return varName;
}
}
let varName = getVarNameFromObject(nameObject);
Not really the best looking thing, but it gets the job done.
This leverages ES6's object destructuring.

hope this help you or Ctrl + Alt + Shift + S => select Dependencies tab and find what you need ( see my image)
A .o object file file (also .obj on Windows) contains compiled object code (that is, machine code produced by your C or C++ compiler), together with the names of the functions and other objects the file contains. Object files are processed by the linker to produce the final executable. If your build process has not produced these files, there is probably something wrong with your makefile/project files.
Simplest way for me is this one (Kotlin)
card_item.backgroundTintList = ColorStateList.valueOf(Color.parseColor("#fc4041"))
Just a minor addition: if you add the -c
flag to ps, you don't need to remove the line containing the grep process with grep -v
afterwards. I.e.
ps acux | grep cron
is all the typing you'll need on a bsd-ish system (this includes MacOSX) You can leave the -u
away if you need less information.
On a system where the genetics of the native ps
command point back to SysV, you'd use
ps -e |grep cron
or
ps -el |grep cron
for a listing containing more than just pid and process name. Of course you could select the specific fields to print out using the -o <field,field,...>
option.
I know this is older but the correct way to do this now is
string Domain = HttpContext.Current.Request.Url.Authority
That will get the DNS or ip address with port for a server.
One solution to the problem that I found was to just set the width in inches. So far I've only tested/confirmed this working in Chrome. It worked well for what I was using it for (to print out an 8.5 x 11 sheet)
@media print {
.printEl {
width: 8.5in;
height: 11in;
}
}
This Blog article explains the internals of ODEX files:
WHAT IS AN ODEX FILE?
In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
I had the same issue.
I was adding items to my ArrayList
outside the UI thread.
Solution: I have done both, adding the items
and called notifyDataSetChanged()
in the UI thread.
Binoj,
I don't think you have to choose one over the other.
The act of moving a dependent class or interface to a class constructor or setter follows the DI pattern. The object you pass to the constructor or set can be implemented with Factory.
When to use? Use the pattern or patterns that are in your developer wheelhouse. What do they feel the most comfortable with and find easiest to understand.
I don't know why but (for now) httpclient can be compiled only as a jar into the libs directory in your project. HttpCore works fine when it is included from mvn like that:
dependencies {
compile 'org.apache.httpcomponents:httpcore:4.4.3'
}
for complete this script , the function for draw circle ,
function drawCircle(coordon)
{
var coord = coordon.split(',');
var c = document.getElementById("myCanvas");
var hdc = c.getContext("2d");
hdc.beginPath();
hdc.arc(coord[0], coord[1], coord[2], 0, 2 * Math.PI);
hdc.stroke();
}
I faced this issue, while connecting DB, the variable to connect to db was not defined.
Cause: php
tried to connect to the db with undefined variable for db host (localhost/127.0.0.1/... any other ip or domain) but failed to trace the domain.
Solution: Make sure the db host
is properly defined.
