Try this:
$("input[type=checkbox]").prop('checked', true).uniform();
You can pass the element into the function <input type="button" value="mybutton1" onclick="dosomething(this)">test
by passing this. Then in the function you can access the value like this:
function dosomething(element) {
console.log(element.value);
}
Installing modules usually requires you to run an sql script that is included with the database installation.
Assuming linux-like OS
find / -name dblink.sql
Verify the location and run it
The reason can be lack of the word static
in some:
final static Logger logging = Logger.getLogger(ProcessorTest.class);
If I make logger the instance field, I am getting exactly this very warning:
No appenders could be found for logger (org.apache.kafka.producer.Sender)
What is worse, the warning points not to ProcessorTest
, where the mistake lives, but to an absolutely different class (Sender) as a source of problems. That class has correct set logger and need not any changes! We could look for the problem for ages!

if your class is not in current assambly you must give qualifiedName and this code shows how to get qualifiedname of class
string qualifiedName = typeof(YourClass).AssemblyQualifiedName;
and then you can get type with qualifiedName
Type elementType = Type.GetType(qualifiedName);

The checked answer does work but officially in MongooseJS latest, you should use pull.
doc.subdocs.push({ _id: 4815162342 }) // added
doc.subdocs.pull({ _id: 4815162342 }) // removed
https://mongoosejs.com/docs/api.html#mongoosearray_MongooseArray-pull
I was just looking that up too.
See Daniel's answer for the correct answer. Much better.
Using JSTL:
<c:set var="message" value='${requestScope["Error_Message"]}' />
Here var sets the variable name and request.getAttribute is equal to requestScope. But it's not essential. ${Error_Message} will give you the same outcome. It'll search every scope. If you want to do some operation with content you take from Error_Message you have to do it using message. like below one.
<c:out value="${message}"/>
This code is based on the most voted question but I might be easier to use

if (userAgent == null || userAgent.isEmpty()) {
toReturn = UNKNOWN;
} else if (userAgent.toLowerCase().contains("windows")) {
toReturn = WINDOWS;
} else if (userAgent.toLowerCase().contains("mac")) {
toReturn = MAC;
} else if (userAgent.toLowerCase().contains("x11")) {
toReturn = LINUX;
} else if (userAgent.toLowerCase().contains("android")) {
toReturn = ANDROID;
} else if (userAgent.toLowerCase().contains("iphone")) {
toReturn = IPHONE;
} else {
toReturn = UNKNOWN;
}
return toReturn;
}
}
I'm not sure there's a clear-cut definition of "framework". Sometimes a large set of libraries is called a framework, but I think the typical use of the word is closer to the definition aioobe brought.
This very nice article sums up the difference between just a set of libraries and a framework:
A framework can be defined as a set of libraries that say “Don’t call us, we’ll call you.”
How does a framework help you? Because instead of writing something from scratch, you basically just extend a given, working application. You get a lot of productivity this way - sometimes the resulting application can be far more elaborate than you could have done on your own in the same time frame - but you usually trade in a lot of flexibility.
Just a cooler swift syntax for Nate's answer:
[UISwipeGestureRecognizerDirection.right,
UISwipeGestureRecognizerDirection.left,
UISwipeGestureRecognizerDirection.up,
UISwipeGestureRecognizerDirection.down].forEach({ direction in
let swipe = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
swipe.direction = direction
self.view.addGestureRecognizer(swipe)
})
Long.parseLong(data)
and catch exception, it handles minus sign.
Although the number of digits is limited this actually creates a variable of the data which can be used, which is, I would imagine, the most common use-case.
This is Working for me
$().popover({container: 'body'})
Try putting your text in another div inside your span:
i.e.

I had this situation restoring a database to an SQL Server 2005 Standard Edition instance using Symantec Backup Exec 11d. After the restore job completed the database remained in a "Restoring" state. I had no disk space issues-- the database simply didn't come out of the "Restoring" state.
I ran the following query against the SQL Server instance and found that the database immediately became usable:
RESTORE DATABASE <database name> WITH RECOVERY
You need to set Opacity first for standards-compliant browsers, then the various versions of IE. See Example:
but this opacity code not work in ie8
.slidedownTrigger
{
cursor: pointer;
opacity: .75; /* Standards Compliant Browsers */
filter: alpha(opacity=75); /* IE 7 and Earlier */
/* Next 2 lines IE8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=75)";
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=75);
}
Note that I eliminated -moz as Firefox is a Standards Compliant browser and that line is no longer necessary. Also, -khtml is depreciated, so I eliminated that style as well.
Furthermore, IE's filters will not validate to w3c standards, so if you want your page to validate, separate your standards stylesheet from your IE stylesheet by using an if IE statement like below:
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="http://www.mysite.com/css/ie.css" />
<![endif]-->
If you separate the ie quirks, your site will validate just fine.
Base on this I was able to solve this by changing the constructor of XmlSerializer
I was using instead of changing the classes.
Instead of using something like this (suggested in the other answers):
[XmlInclude(typeof(Derived))]
public class Base {}
public class Derived : Base {}
public void Serialize()
{
TextWriter writer = new StreamWriter(SchedulePath);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>));
xmlSerializer.Serialize(writer, data);
writer.Close();
}
I did this:
public class Base {}
public class Derived : Base {}
public void Serialize()
{
TextWriter writer = new StreamWriter(SchedulePath);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>), new[] { typeof(Derived) });
xmlSerializer.Serialize(writer, data);
writer.Close();
}
Sort the array just as before, but print the elements out in reverse order, using a loop that counts down rather than counting up.
Also, move the sort out of the loop - you are currently sorting the array over and over again when you only need to sort it once.
Arrays.sort(arr);
for(int i = 0; i < arr.length; i++){
//Arrays.sort(arr); // not here
System.out.print( " " +arr[i]);
}
for(int i = arr.length-1; i >= 0; i--){
//Arrays.sort(arr); // not here
System.out.print( " " +arr[i]);
}
You can do something like:
s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ),
linewidth=2, color='r')
plt.show()
Login to virtual machine use below command to check ip address. (anyone will work)
If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1
If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine
Try this

Just use method "text()".
The .text() method cannot be used on form inputs or scripts. To set or get the text value of input or textarea elements, use the .val() method. To get the value of a script element, use the .html() method.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:
GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly which links here in the accepted answer (from the original poster, no less): http://help.github.com/linux-set-up-git/
It's worth mentioning that in some cases
File myFolder = new File("directory");
doesn't point to the root elements. For example when you place your application on C:
drive (C:\myApp.jar
) then myFolder
points to (windows)
C:\Users\USERNAME\directory
instead of
C:\Directory
It's actually not really clearly stated in the standard (RFC 3986) whether a percent-encoded version of .
or ..
is supposed to have the same this-folder/up-a-folder meaning as the unescaped version. Section 3.3 only talks about “The path segments .
and ..
”, without clarifying whether they match .
and ..
before or after pct-encoding.
Personally I find Firefox's interpretation that %2E
does not mean .
most practical, but unfortunately all the other browsers disagree. This would mean that you can't have a path component containing only .
or ..
.
I think the only possible suggestion is “don't do that”! There are other path components that are troublesome too, typically due to server limitations: %2F
, %00
and %5C
sequences in paths may also be blocked by some web servers, and the empty path segment can also cause problems. So in general it's not possible to fit all possible byte sequences into a path component.
I have spent the last few days trying to figure this out myself. Using the old json dataType gives you cross origin problems, while setting the dataType to jsonp makes the data "unreadable" as explained above. So there are apparently two ways out, the first hasn't worked for me but seems like a potential solution and that I might be doing something wrong. This is explained here [ https://learn.jquery.com/ajax/working-with-jsonp/ ].
The one that worked for me is as follows: 1- download the ajax cross origin plug in [ http://www.ajax-cross-origin.com/ ]. 2- add a script link to it just below the normal jQuery link. 3- add the line "crossOrigin: true," to your ajax function.
Good to go! here is my working code for this:
$.ajax({_x000D_
crossOrigin: true,_x000D_
url : "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.86,151.195&radius=5000&type=ATM&keyword=ATM&key=MyKey",_x000D_
type : "GET",_x000D_
success:function(data){_x000D_

I know you asked for non-looping solutions, but the only solutions I can come up with probably loop internally anyway:
map(int,y)
or:
[i*1 for i in y]
or:
import numpy
y=numpy.array(y)
y*1
There are companies that provide this service. Service bureaus that deal with mass mailing will scrub an entire mailing list to that it's in the proper format, which results in a discount on postage. The USPS sells databases of address information that can be used to develop custom solutions. They also have lists of approved vendors who provide this kind of software and service.
There are some (but not many) packages that have APIs for hooking address validation into your software.
However, you're right that its a pretty nasty problem.
Try to use rbindlist
approach over rbind
as it's very, very fast.
Example:
library(data.table)
##### example 1: slow processing ######
table.1 <- data.frame(x = NA, y = NA)
time.taken <- 0
for( i in 1:100) {
start.time = Sys.time()
x <- rnorm(100)
y <- x/2 +x/3
z <- cbind.data.frame(x = x, y = y)
table.1 <- rbind(table.1, z)
end.time <- Sys.time()
time.taken <- (end.time - start.time) + time.taken
}
print(time.taken)
> Time difference of 0.1637917 secs
####example 2: faster processing #####
table.2 <- list()
t0 <- 0
for( i in 1:100) {
s0 = Sys.time()
x <- rnorm(100)
y <- x/2 + x/3
z <- cbind.data.frame(x = x, y = y)
table.2[[i]] <- z
e0 <- Sys.time()
t0 <- (e0 - s0) + t0
}
s1 = Sys.time()
table.3 <- rbindlist(table.2)
e1 = Sys.time()
t1 <- (e1-s1) + t0
t1
> Time difference of 0.03064394 secs
I mean a prompt script would work if the variable was not needed for the HTML aspect, even then in certain situations, a function could be used.
var save_user_input = prompt('what needs to be saved?');
//^ makes a variable of the prompt's answer
if (save_user_input == null) {
//^ if the answer is null, it is nothing
//however, if it is nothing, it is cancelled (as seen below). If it is "null" it is what the user said, then assigned to the variable(i think), but also null as in nothing in the prompt answer window, but ok pressed. So you cant do an or "null" (which would look like: if (save_user_input == null || "null") {)because (I also don't really know if this is right) the variable is "null". Very confusing
alert("cancelled");
//^ alerts the user the cancel button was pressed. No long explanation this time.
}
//^ is an end for the if (i got stumped as to why it wasn’t working and then realised this. very important to remember.)
else {
alert(save_user_input + " is what you said");
//^ alerts the user the variable and adds the string " is what you said" on the end
}

As long as you specify a width on the element, it should wrap itself without needing anything else.
I had a similar problem just now and my solution might help. I'm using an iframe to upload and convert an xml file to json and send it back behind the scenes, and Chrome was adding some garbage to the incoming data that only would show up intermittently and cause the "Uncaught SyntaxError: Unexpected token o" error.
I was accessing the iframe data like this:
$('#load-file-iframe').contents().text()
which worked fine on localhost, but when I uploaded it to the server it stopped working only with some files and only when loading the files in a certain order. I don't really know what caused it, but this fixed it. I changed the line above to
$('#load-file-iframe').contents().find('body').text()
once I noticed some garbage in the HTML response.
Long story short check your raw HTML response data and you might turn something up.
If you are not sure Object.keys() is going to return you the keys in the right order, you can try this logic instead
var keys = []
var obj = {
'key1' : 'value1',
'key2' : 'value2',
'key3' : 'value3',
}
for (var key in obj){
keys.push(key)
}
console.log(obj[keys[1]])
console.log(obj[keys[2]])
console.log(obj[keys[3]])
As of today, you can read some values from HTML5 data
attributes in CSS3 declarations. In CaioToOn's fiddle the CSS code can use the data
properties for setting the content
.
Unfortunately it is not working for the width
and height
(tested in Google Chrome 35, Mozilla Firefox 30 & Internet Explorer 11).
But there is a CSS3 attr() Polyfill from Fabrice Weinberg which provides support for data-width
and data-height
. You can find the GitHub repo to it here: cssattr.js.

Many problems for which no efficient algorithm to find an optimal solution is known have heuristic approaches that yield near-optimal results very quickly.
There are some overlaps: "genetic algorithms" is an accepted term, but strictly speaking, those are heuristics, not algorithms.
Other way to solve the problem of space reclaiming is, Create multiple partitions within table - Range based, Value based partitions and just drop/truncate the partition to reclaim the space, which will release the space used by whole data stored in the particular partition.
There will be some changes needed in table schema when you introduce the partitioning for your table like - Unique Keys, Indexes to include partition column etc.
Couldn't you just add it as an environment variable in Jenkins settings:

You are loading .dll
so your OS has to be windows.
First check which php.ini
file you are using by running phpinfo()
Then check where your extensions folder is by checking extension_dir
attribute in that file.
Next make sure that php_curl.dll
is present in that folder. If not copy it over.
Restart apache
and check if it works.
Since you installed packages individually, also do this:
Copy the dll file from php_installation_folder/extensions
to apache_installation_folder/bin
try this:
import sys
sys.argv = ['arg1', 'arg2']
execfile('abc.py')
Note that when abc.py
finishes, control will be returned to the calling program. Note too that abc.py
can call quit()
if indeed finished.
This will work:
$stringToSplit = 'This is my String!' ."\n\r". 'Second Line';
$split = explode (
' ', implode (
' ', explode (
"\n\r", $stringToSplit
)
)
);
As you can see, it first glues the by \n\r exploded parts together with a space, to then cut it apart again, this time taking the spaces with him.
JavascriptExecutor is best to scroll down a web page
window.scrollTo
Function in JavascriptExecutor can do this
JavascriptExecutor js = ((JavascriptExecutor) driver);
js.executeScript("window.scrollTo(0,100");
Above code will scroll down by 100 y coordinates
A modern approach without Jquery is to use the FileList object you get back from <input type="file">
when user selects a file(s) and then use Fetch to post the FileList wrapped around a FormData object.
// The input DOM element // <input type="file">
const inputElement = document.querySelector('input[type=file]');
// Listen for a file submit from user
inputElement.addEventListener('change', () => {
const data = new FormData();
data.append('file', inputElement.files[0]);
data.append('imageName', 'flower');
// You can then post it to your server.
// Fetch can accept an object of type FormData on its body
fetch('/uploadImage', {
method: 'POST',
body: data
});
});
Differences in SOAP versions
Both SOAP Version 1.1 and SOAP Version 1.2 are World Wide Web Consortium (W3C) standards. Web services can be deployed that support not only SOAP 1.1 but also support SOAP 1.2. Some changes from SOAP 1.1 that were made to the SOAP 1.2 specification are significant, while other changes are minor.
The SOAP 1.2 specification introduces several changes to SOAP 1.1. This information is not intended to be an in-depth description of all the new or changed features for SOAP 1.1 and SOAP 1.2. Instead, this information highlights some of the more important differences between the current versions of SOAP.
The changes to the SOAP 1.2 specification that are significant include the following updates: SOAP 1.1 is based on XML 1.0. SOAP 1.2 is based on XML Information Set (XML Infoset). The XML information set (infoset) provides a way to describe the XML document with XSD schema. However, the infoset does not necessarily serialize the document with XML 1.0 serialization on which SOAP 1.1 is based.. This new way to describe the XML document helps reveal other serialization formats, such as a binary protocol format. You can use the binary protocol format to compact the message into a compact format, where some of the verbose tagging information might not be required.
In SOAP 1.2 , you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units. The HTTP binding that is specified in SOAP 1.2 - Part 2 uses XML 1.0 as the serialization of the SOAP message infoset.
SOAP 1.2 provides the ability to officially define transport protocols, other than using HTTP, as long as the vendor conforms to the binding framework that is defined in SOAP 1.2. While HTTP is ubiquitous, it is not as reliable as other transports including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability (WS-I) profiles. The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1.2 implementations. SOAP with Attachments API for Java (SAAJ) can also stand alone as a simple mechanism to issue SOAP requests. A major change to the SAAJ specification is the ability to represent SOAP 1.1 messages and the additional SOAP 1.2 formatted messages. For example, SAAJ Version 1.3 introduces a new set of constants and methods that are more conducive to SOAP 1.2 (such as getRole(), getRelay()) on SOAP header elements. There are also additional methods on the factories for SAAJ to create appropriate SOAP 1.1 or SOAP 1.2 messages. The XML namespaces for the envelope and encoding schemas have changed for SOAP 1.2. These changes distinguish SOAP processors from SOAP 1.1 and SOAP 1.2 messages and supports changes in the SOAP schema, without affecting existing implementations. Java Architecture for XML Web Services (JAX-WS) introduces the ability to support both SOAP 1.1 and SOAP 1.2. Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time, there became a need to represent this message in its appropriate SOAP context. In JAX-WS, a number of additional enhancements result from the support for SAAJ 1.3.
There is not difine POST AND GET method for particular android....but all here is differance
GET The GET method appends name/value pairs to the URL, allowing you to retrieve a resource representation. The big issue with this is that the length of a URL is limited (roughly 3000 char) resulting in data loss should you have to much stuff in the form on your page, so this method only works if there is a small number parameters.
What does this mean for me? Basically this renders the GET method worthless to most developers in most situations. Here is another way of looking at it: the URL could be truncated (and most likely will be give today's data-centric sites) if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser (YIKES!!!) not the best place for any kind of sensitive (or even non-sensitive) data to be shown because you are just begging the curious user to mess with it.
POST The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output, basically its a no-brainer on which one to use. POST is also more secure but certainly not safe. Although HTTP fully supports CRUD, HTML 4 only supports issuing GET and POST requests through its various elements. This limitation has held Web applications back from making full use of HTTP, and to work around it, most applications overload POST to take care of everything but resource retrieval.
simple solution
const handler1 = {
construct(target, args) {
let newDate = new target(...args);
var tzDifference = newDate.getTimezoneOffset();
return new target(newDate.getTime() + tzDifference * 60 * 1000);
}
};
Date = new Proxy(Date, handler1);
Use a double-negative:
/[^\S\r\n]/
That is, not-not-whitespace (the capital S complements) or not-carriage-return or not-newline. Distributing the outer not (i.e., the complementing ^
in the character class) with De Morgan's law, this is equivalent to “whitespace but not carriage return or newline.” Including both \r
and \n
in the pattern correctly handles all of Unix (LF), classic Mac OS (CR), and DOS-ish (CR LF) newline conventions.
No need to take my word for it:
#! /usr/bin/env perl
use strict;
use warnings;
use 5.005; # for qr//
my $ws_not_crlf = qr/[^\S\r\n]/;
for (' ', '\f', '\t', '\r', '\n') {
my $qq = qq["$_"];
printf "%-4s => %s\n", $qq,
(eval $qq) =~ $ws_not_crlf ? "match" : "no match";
}
Output:
" " => match "\f" => match "\t" => match "\r" => no match "\n" => no match
Note the exclusion of vertical tab, but this is addressed in v5.18.
Before objecting too harshly, the Perl documentation uses the same technique. A footnote in the “Whitespace” section of perlrecharclass reads
Prior to Perl v5.18,
\s
did not match the vertical tab.[^\S\cK]
(obscurely) matches what\s
traditionally did.
The same section of perlrecharclass also suggests other approaches that won’t offend language teachers’ opposition to double-negatives.
Outside locale and Unicode rules or when the /a
switch is in effect, “\s
matches [\t\n\f\r ]
and, starting in Perl v5.18, the vertical tab, \cK
.” Discard \r
and \n
to leave /[\t\f\cK ]/
for matching whitespace but not newline.
If your text is Unicode, use code similar to the sub below to construct a pattern from the table in the aforementioned documentation section.

The double-negative trick is also handy for matching alphabetic characters too. Remember that \w
matches “word characters,” alphabetic characters and digits and underscore. We ugly-Americans sometimes want to write it as, say,
if (/[A-Za-z]+/) { ... }
but a double-negative character-class can respect the locale:
if (/[^\W\d_]+/) { ... }
Expressing “a word character but not digit or underscore” this way is a bit opaque. A POSIX character-class communicates the intent more directly
if (/[[:alpha:]]+/) { ... }
or with a Unicode property as szbalint suggested
if (/\p{Letter}+/) { ... }
Here is example code you could run to make such test:
var f = 10000000;
var p = new int[f];
for(int i = 0; i < f; ++i)
{
p[i] = i % 2;
}
var time = DateTime.Now;
p.Sum();
Console.WriteLine(DateTime.Now - time);
int x = 0;
time = DateTime.Now;
foreach(var item in p){
x += item;
}
Console.WriteLine(DateTime.Now - time);
x = 0;
time = DateTime.Now;
for(int i = 0, j = f; i < j; ++i){
x += p[i];
}
Console.WriteLine(DateTime.Now - time);
The same example for complex object is:
void Main()
{
var f = 10000000;
var p = new Test[f];
for(int i = 0; i < f; ++i)
{
p[i] = new Test();
p[i].Property = i % 2;
}
var time = DateTime.Now;
p.Sum(k => k.Property);
Console.WriteLine(DateTime.Now - time);
int x = 0;
time = DateTime.Now;
foreach(var item in p){
x += item.Property;
}
Console.WriteLine(DateTime.Now - time);
x = 0;
time = DateTime.Now;
for(int i = 0, j = f; i < j; ++i){
x += p[i].Property;
}
Console.WriteLine(DateTime.Now - time);
}
class Test
{
public int Property { get; set; }
}
My results with compiler optimizations off are:
00:00:00.0570370 : Sum()
00:00:00.0250180 : Foreach()
00:00:00.0430272 : For(...)
and for second test are:
00:00:00.1450955 : Sum()
00:00:00.0650430 : Foreach()
00:00:00.0690510 : For()
it looks like LINQ is generally slower than foreach(...) but what is weird for me is that foreach(...) appears to be faster than for loop.
There is also a difference in indexing.
interface MyInterface {
foobar: string;
}
type MyType = {
foobar: string;
}
const exampleInterface: MyInterface = { foobar: 'hello world' };
const exampleType: MyType = { foobar: 'hello world' };
let record: Record<string, string> = {};
record = exampleType; // Compiles
record = exampleInterface; // Index signature is missing
So please consider this example, if you want to index your object
Take a look on this question
Using DataTable is valid as user927524 stated. You can also do it by adding rows manually, which will not require to add a specific wrapping class:
List<string> filenamesList = ...;
foreach(string filename in filenamesList)
gvFilesOnServer.Rows.Add(new object[]{filename});
In any case, thanks user927524 for clearing this weird behavior!!
Working example. Notes below.
class Animal {
constructor(public name) {
}
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
move() {
alert(this.name + " is Slithering...");
super.move(5);
}
}
class Horse extends Animal {
move() {
alert(this.name + " is Galloping...");
super.move(45);
}
}
var sam = new Snake("Sammy the Python");
var tom: Animal = new Horse("Tommy the Palomino");
sam.move();
tom.move(34);
You don't need to manually assign the name to a public variable. Using public name
in the constructor definition does this for you.
You don't need to call super(name)
from the specialised classes.
Using this.name
works.
Notes on use of super
.
This is covered in more detail in section 4.9.2 of the language specification.
The behaviour of the classes inheriting from Animal
is not dissimilar to the behaviour in other languages. You need to specify the super
keyword in order to avoid confusion between a specialised function and the base class function. For example, if you called move()
or this.move()
you would be dealing with the specialised Snake
or Horse
function, so using super.move()
explicitly calls the base class function.
There is no confusion of properties, as they are the properties of the instance. There is no difference between super.name
and this.name
- there is simply this.name
. Otherwise you could create a Horse that had different names depending on whether you were in the specialized class or the base class.
A group of 8 bits is called a byte ( with the exception where it is not :) for certain architectures )
A word is a fixed sized group of bits that are handled as a unit by the instruction set and/or hardware of the processor. That means the size of a general purpose register ( which is generally more than a byte ) is a word
In the C, a word is most often called an integer => int
The closest you will ever get to doing such thing is a dissasembler, or debug info (Log2Vis.pdb).
An alternative is to use the Alpine Linux containers, e.g. python:2.7-alpine
. They offer pip
out of the box (and have a smaller footprint which leads to faster builds etc).
Here's a simple function -
function getNumberFromCurrency(currency) {
return Number(currency.replace(/[$,]/g,''))
}
console.log(getNumberFromCurrency('$1,000,000.99')) // 1000000.99

When you reference Range like that it's called an unqualified reference because you don't specifically say which sheet the range is on. Unqualified references are handled by the "_Global" object that determines which object you're referring to and that depends on where your code is.
If you're in a standard module, unqualified Range will refer to Activesheet. If you're in a sheet's class module, unqualified Range will refer to that sheet.
inputTemplateContent is a variable that contains a reference to a range, probably a named range. If you look at the RefersTo property of that named range, it likely points to a sheet other than the Activesheet at the time the code executes.
The best way to fix this is to avoid unqualified Range references by specifying the sheet. Like
With ThisWorkbook.Worksheets("Template")
.Range(inputTemplateHeader).Value = NO_ENTRY
.Range(inputTemplateContent).Value = NO_ENTRY
End With
Adjust the workbook and worksheet references to fit your particular situation.
Just in case if you want to do this using an npm package semver
link
let fs = require('fs');
let semver = require('semver');
if (fs.existsSync('./package.json')) {
var package = require('./package.json');
let currentVersion = package.version;
let type = process.argv[2];
if (!['major', 'minor', 'patch'].includes(type)) {
type = 'patch';
}
let newVersion = semver.inc(package.version, type);
package.version = newVersion;
fs.writeFileSync('./package.json', JSON.stringify(package, null, 2));
console.log('Version updated', currentVersion, '=>', newVersion);
}
package.json
should look like,
{
"name": "versioning",
"version": "0.0.0",
"description": "Update version in package.json using npm script",
"main": "version.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"version": "node version.js"
},
"author": "Bhadresh Arya",
"license": "ISC",
"dependencies": {
"semver": "^7.3.2"
}
}
just pass major
, minor
, patch
argument with npm run version
. Default will be patch
.
example:
npm run version
or npm run verison patch
or npm run verison minor
or npm run version major
For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:
db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } ,
{$inc : {"items.$.price" : 1} } ,
false ,
true);
Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.
The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:
db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} ,
{$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
false ,
true);
For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:
db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
{$inc : {total : 1 , "items.$.price" : 1}} ,
false ,
true);
i suggest using phpmyadmin
it’s definitely the best free tool out there and it works on every system with php+mysql
I've just written a new (friendly) command line utility to do this. It doesn’t rely on Finder/AppleScript, or on any of the (deprecated) Alias Manager APIs, and it’s easy to configure and use.
Anyway, anyone who is interested can find it on PyPi; the documentation is available on Read The Docs.
You can determine if as certain word is found in a cell by using
If InStr(cell.Value, "Word1") > 0 Then
If Word1 is found in the string the InStr()
function will return the location of the first character of Word1 in the string.
There are two ways you could do this. Either create your own custom exception class to represent a divide by zero error or throw the same type of exception the java runtime would throw in this situation.
public class DivideByZeroException() extends ArithmeticException {
}
Then in your code you would check for a divide by zero and throw this exception:
if (divisor == 0) throw new DivideByZeroException();
Add to your code the check for a divide by zero and throw an arithmetic exception:
if (divisor == 0) throw new java.lang.ArithmeticException("/ by zero");
Additionally, you could consider throwing an illegal argument exception since a divisor of zero is an incorrect argument to pass to your setKp() method:
if (divisor == 0) throw new java.lang.IllegalArgumentException("divisor == 0");
Often times configmaps or secrets are injected as configuration files in containers. Depending on the application a restart may be required should those be updated with a subsequent helm upgrade
, but if the deployment spec itself didn't change the application keeps running with the old configuration resulting in an inconsistent deployment.
The sha256sum
function can be used together with the include
function to ensure a deployments template section is updated if another spec changes:
kind: Deployment
spec:
template:
metadata:
annotations:
checksum/config: {{ include (print $.Template.BasePath "/secret.yaml") . | sha256sum }}
[...]
In my case, for some reasons, $.Template.BasePath
didn't work but $.Chart.Name
does:
spec:
replicas: 1
template:
metadata:
labels:
app: admin-app
annotations:
checksum/config: {{ include (print $.Chart.Name "/templates/" $.Chart.Name "-configmap.yaml") . | sha256sum }}
The below example didnt quite work for me,this is the version that i made work!

As others pointed out if you are allowed to use a framework like jQuery the best thing to do is use it, as it high likely will do it in the best possible way. If you are not allowed to use a framework then I guess manipulating the DOM is the best way to do it (and in my opinion, the right way to do it).
Yes, it does. The way to enable this depends on your version of Notepad++. On newer versions you can use:
Menu View ? Show Symbol ? *Show All Characters`
or
Menu View ? Show Symbol ? Show White Space and TAB
(Thanks to bers' comment and bkaid's answers below for these updated locations.)
On older versions you can look for:
Menu View ? Show all characters
or
Menu View ? Show White Space and TAB
s.Substring(0, s.IndexOf(" ", s.IndexOf(" ") + 1))
.....
$("#testID #testID2").removeClass("test2").addClass("test3");
Because you have assigned an id to img too, you can simply do this too:
$("#testID2").removeClass("test2").addClass("test3");
And finally, you can do this too:
$("#testID img").removeClass("test2").addClass("test3");
Similar question has been asked in stackoverflow before.
See here: PHP $_SERVER['HTTP_HOST'] vs. $_SERVER['SERVER_NAME'], am I understanding the man pages correctly?
Also see this article: http://shiflett.org/blog/2006/mar/server-name-versus-http-host
Recommended using HTTP_HOST, and falling back on SERVER_NAME only if HTTP_HOST was not set. He said that SERVER_NAME could be unreliable on the server for a variety of reasons, including:
- no DNS support
- misconfigured
- behind load balancing software
I solved a situation where I needed a template for the element that would handle alternatively a regular URL or a javascript call, where the js function needs a reference to the calling element. In javascript, "this" works as a self reference only in the context of a form element, e.g., a button. I didn't want a button, just the apperance of a regular link.
Examples:
<a onclick="http://blahblah" href="http://blahblah" target="_blank">A regular link</a>
<a onclick="javascript:myFunc($(this));return false" href="javascript:myFunc($(this));" target="_blank">javascript with self reference</a>
The href and onClick attributes have the same values, exept I append "return false" on onClick when it's a javascript call. Having "return false" in the called function did not work.
You can also try viewing the graph in a browser.
Use the following:
matplotlib.use('WebAgg')
Make sure that while using : Button "varName" =findViewById("btID"); you put in the right "btID". I accidentally put in the id of a button from another similar activity and it showed the same error. Hope it helps.
Put this in your server directive:
location /issue {
rewrite ^/issue(.*) http://$server_name/shop/issues/custom_issue_name$1 permanent;
}
Or duplicate it:
location /issue1 {
rewrite ^/.* http://$server_name/shop/issues/custom_issue_name1 permanent;
}
location /issue2 {
rewrite ^.* http://$server_name/shop/issues/custom_issue_name2 permanent;
}

I guess you should add android:centerColor
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#FFFFFF"
android:centerColor="#000000"
android:endColor="#FFFFFF"
android:angle="0" />
</shape>
This example displays a horizontal gradient from white to black to white.
Three things to note:
1)Working Directory ----- folder where our codes file are present
2)Local Repository ------ This is inside our system. When we first time make
COMMIT command then this Local Repository is created.
in the same place where is our Working directory ,
Checkit ( .git ) file get created.
After that when ever we do commit , this will store the
changes we make in the file of Working Directory to
local Repository (.git)
3)Remote Repository ----- This is situated outside our system like on servers located any where in the world . like github. When we make PUSH command then codes from our local repository get stored to this Remote Repository
As @cs95 mentioned in a comment, to drop only one level, use:
df.reset_index(level=[...])
This avoids having to redefine your desired index after reset.
Some benefits of using getters and setters (known as encapsulation
or data-hiding
):
(originally answered here)
1. The fields of a class can be made read-only (by only providing the getter) or write-only (by only providing the setter). This gives the class a total control of who gets to access/modify its fields.
Example:
class EncapsulationExample {
private int readOnly = -1; // this value can only be read, not altered
private int writeOnly = 0; // this value can only be changed, not viewed
public int getReadOnly() {
return readOnly;
}
public int setWriteOnly(int w) {
writeOnly = w;
}
}
2. The users of a class do not need to know how the class actually stores the data. This means data is separated and exists independently from the users thus allowing the code to be more easily modified and maintained. This allows the maintainers to make frequent changes like bug fixes, design and performance enhancements, all while not impacting users.
Furthermore, encapsulated resources are uniformly accessible to each user and have identical behavior independent of the user since this behavior is internally defined in the class.
Example (getting a value):
class EncapsulationExample {
private int value;
public int getValue() {
return value; // return the value
}
}
Now what if I wanted to return twice the value instead? I can just alter my getter and all the code that is using my example doesn't need to change and will get twice the value:
class EncapsulationExample {
private int value;
public int getValue() {
return value*2; // return twice the value
}
}
3. Makes the code cleaner, more readable and easier to comprehend.
Here is an example:
No encapsulation:
class Box {
int widthS; // width of the side
int widthT; // width of the top
// other stuff
}
// ...
Box b = new Box();
int w1 = b.widthS; // Hm... what is widthS again?
int w2 = b.widthT; // Don't mistake the names. I should make sure I use the proper variable here!
With encapsulation:
class Box {
private int widthS; // width of the side
private int widthT; // width of the top
public int getSideWidth() {
return widthS;
}
public int getTopWIdth() {
return widthT;
}
// other stuff
}
// ...
Box b = new Box();
int w1 = b.getSideWidth(); // Ok, this one gives me the width of the side
int w2 = b.getTopWidth(); // and this one gives me the width of the top. No confusion, whew!
Look how much more control you have on which information you are getting and how much clearer this is in the second example. Mind you, this example is trivial and in real-life the classes you would be dealing with a lot of resources being accessed by many different components. Thus, encapsulating the resources makes it clearer which ones we are accessing and in what way (getting or setting).
Here is good SO thread
on this topic.
Here is good read
on data encapsulation.
If you are using Anaconda you should add the Anaconda path.

For PowerShell (pwsh
, not bash
), this was quite a rube-goldberg solution... My first attempt was to wrap the calls to mysql
in a try/catch
function, but due to some strange behavior in PowerShell error handling, this wasn't viable.
The solution was to override the $ErrorActionPreference
just long enough to combine and capture STDERR
and STDOUT
and parse for the word ERROR
and re-throw as needed. The reason we couldn't catch and release on "^mysql.*Warning.*password"
is because PowerShell handles and raises the error as one stream, so you must capture it all in order to filter and re-throw. :/
Function CallMySQL() {
# Cache the error action preference
$_temp = $ErrorActionPreference
$ErrorActionPreference = "Continue"
# Capture all output from mysql
$output = (&mysql --user=foo --password=bar 2>&1)
# Restore the error action preference
$ErrorActionPreference = $_temp
if ($output -match "ERROR") {
throw $output
} elseif($output) {
" Swallowing $output"
} else {
" No output"
}
}
Note: PowerShell is available for Unix, so this solution is cross-platform. It can be adapted to bash
with some minor syntax modifications.
Warning: There are dozens of edge-cases where this won't work such as non-english error messages or statements that return the word ERROR
anywhere in the output, but it was enough to swallow the warning for a basic call to mysql
without bombing out the entire script. Hopefully others find this useful.
It would be nice if mysql
simply added an option to suppress this warning.
If you know your commit was recent instead of going through the entire tree do the following:
git filter-branch --tree-filter 'rm LARGE_FILE.zip' HEAD~10..HEAD
p
is the conversion specifier to print pointers. Use this.
int a = 42;
printf("%p\n", (void *) &a);
Remember that omitting the cast is undefined behavior and that printing with p
conversion specifier is done in an implementation-defined manner.
I prefer this variant on the enumerator method with a pipeline, because you don't have to refer to the hash table in the foreach (tested in PowerShell 5):
$hash = @{
'a' = 3
'b' = 2
'c' = 1
}
$hash.getEnumerator() | foreach {
Write-Host ("Key = " + $_.key + " and Value = " + $_.value);
}
Output:
Key = c and Value = 1
Key = b and Value = 2
Key = a and Value = 3
Now, this has not been deliberately sorted on value, the enumerator simply returns the objects in reverse order.
But since this is a pipeline, I now can sort the objects received from the enumerator on value:
$hash.getEnumerator() | sort-object -Property value -Desc | foreach {
Write-Host ("Key = " + $_.key + " and Value = " + $_.value);
}
Output:
Key = a and Value = 3
Key = b and Value = 2
Key = c and Value = 1
When a thread object goes out of scope and it is in joinable state, the program is terminated. The Standard Committee had two other options for the destructor of a joinable thread. It could quietly join -- but join might never return if the thread is stuck. Or it could detach the thread (a detached thread is not joinable). However, detached threads are very tricky, since they might survive till the end of the program and mess up the release of resources. So if you don't want to terminate your program, make sure you join (or detach) every thread.
ReSharper offers a Generate Constructor tool where you can select any field/properties that you want initialized. I use the Alt + Ins hot-key to access this.
If I got you right, are you trying like this?
into this?
in your Form1, add this event in your button:
// button event in your Form1
private void button1_Click(object sender, EventArgs e)
{
Form2 f2 = new Form2();
f2.ShowDialog(); // Shows Form2
}
then, in your Form2 add also this event in your button:
// button event in your Form2
private void button1_Click(object sender, EventArgs e)
{
Form3 f3 = new Form3(); // Instantiate a Form3 object.
f3.Show(); // Show Form3 and
this.Close(); // closes the Form2 instance.
}
Just make a comparison function/functor:
bool my_cmp(const data& a, const data& b)
{
// smallest comes first
return a.word.size() < b.word.size();
}
std::sort(info.begin(), info.end(), my_cmp);
Or provide an bool operator<(const data& a) const
in your data
class:
struct data {
string word;
int number;
bool operator<(const data& a) const
{
return word.size() < a.word.size();
}
};
or non-member as Fred said:
struct data {
string word;
int number;
};
bool operator<(const data& a, const data& b)
{
return a.word.size() < b.word.size();
}
and just call std::sort()
:
std::sort(info.begin(), info.end());
A great reason to use 'git reset --soft <sha1>
' is to move HEAD
in a bare repo.
If you try to use the --mixed
or --hard
option, you'll get an error since you're trying to modify and working tree and/or index that does not exist.
Note: You will need to do this directly from the bare repo.
Note Again: You will need to make sure the branch you want to reset in the bare repo is the active branch. If not, follow VonC's answer on how to update the active branch in a bare repo when you have direct access to the repo.

Here's a solution which will work even when JavaScript is disabled:
<form action="login.html">
<button type="submit">Login</button>
</form>
The trick is to surround the button with its own <form>
tag.
I personally prefer the <button>
tag, but you can do it with <input>
as well:
<form action="login.html">
<input type="submit" value="Login"/>
</form>
You could bind the DropDownList to a data source (DataTable, List, DataSet, SqlDataSource, etc).
For example, if you wanted to use a DataTable:
ddlSubject.DataSource = subjectsTable;
ddlSubject.DataTextField = "SubjectNamne";
ddlSubject.DataValueField = "SubjectID";
ddlSubject.DataBind();
EDIT - More complete example
private void LoadSubjects()
{
DataTable subjects = new DataTable();
using (SqlConnection con = new SqlConnection(connectionString))
{
try
{
SqlDataAdapter adapter = new SqlDataAdapter("SELECT SubjectID, SubjectName FROM Students.dbo.Subjects", con);
adapter.Fill(subjects);
ddlSubject.DataSource = subjects;
ddlSubject.DataTextField = "SubjectNamne";
ddlSubject.DataValueField = "SubjectID";
ddlSubject.DataBind();
}
catch (Exception ex)
{
// Handle the error
}
}
// Add the initial item - you can add this even if the options from the
// db were not successfully loaded
ddlSubject.Items.Insert(0, new ListItem("<Select Subject>", "0"));
}
To set an initial value via the markup, rather than code-behind, specify the option(s) and set the AppendDataBoundItems attribute to true:
<asp:DropDownList ID="ddlSubject" runat="server" AppendDataBoundItems="true">
<asp:ListItem Text="<Select Subject>" Value="0" />
</asp:DropDownList>
You could then bind the DropDownList to a DataSource in the code-behind (just remember to remove:
ddlSubject.Items.Insert(0, new ListItem("<Select Subject>", "0"));
from the code-behind, or you'll have two "" items.
I'll give you a very different but real example: I write javascript code to be run in a browser. HTML tags have ID values, but there are constraints on what characters are valid in an ID.
But I want my ID to losslessly refer to files in my file system. Files in reality can have all manner of weird and wonderful characters in them from exclamation marks, accented characters, tilde, even emoji! I cannot do this:
<div id="/path/to/my_strangely_named_file!@().jpg">
<img src="http://myserver.com/path/to/my_strangely_named_file!@().jpg">
Here's a pic I took in Moscow.
</div>
Suppose I want to run some code like this:
# ERROR
document.getElementById("/path/to/my_strangely_named_file!@().jpg");
I think this code will fail when executed.
With Base64 I can refer to something complicated without worrying about which language allows what special characters and which need escaping:
document.getElementById("18GerPD8fY4iTbNpC9hHNXNHyrDMampPLA");
Unlike using an MD5 or some other hashing function, you can reverse the encoding to find out what exactly the data was that actually useful.
I wish I knew about Base64 years ago. I would have avoided tearing my hair out with ‘encodeURIComponent
’ and str.replace(‘\n’,’\\n’)
If you're trying to pass complex data over ssh (e.g. a dotfile so you can get your shell personalizations), good luck doing it without Base 64. This is how you would do it with base 64 (I know you can use SCP, but that would take multiple commands - which complicates key bindings for sshing into a server):
You have to interrupt the execution thread to allow the input to update.
$(document).ready(function(event) {
$("#dSuggest").keypress(function() {
//Interrupt the execution thread to allow input to update
setTimeout(function() {
var dInput = $('input:text[name=dSuggest]').val();
console.log(dInput);
$(".dDimension:contains('" + dInput + "')").css("display","block");
}, 0);
});
});
Try this:
$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);
http://api.cakephp.org/2.3/class-Model.html#_getDataSource
You will have to do this for each datasource if you have more than one though.
I resolved my issue with these commands:
sudo mkdir /usr/local/Cellar
sudo mkdir /usr/local/opt
sudo chown -R $(whoami) /usr/local/Cellar
sudo chown -R $(whoami) /usr/local/opt
$(document).height:
if your device height
was bigger. Your page has Not any scroll;
$(document).height:
assume you have not scroll and return this height
;
$(window).height:
return your page height
on your device.
I'm sticking with DbVisualizer Free until something better comes along.
EDIT/UPDATE: been using https://dbeaver.io/ lately, really enjoying this
You cannot use height: 0
and height: auto
to transition the height. auto
is always relative and cannot be transitioned towards. You could however use max-height: 0
and transition that to max-height: 9999px
for example.
Sorry I couldn't comment, my rep isn't high enough...
Could do this, but then the user has to separate the numbers by a space:
#include "stdio.h"
int main()
{
int minx, x, y, z;
printf("Enter four ints: ");
scanf( "%i %i %i %i", &minx, &x, &y, &z);
printf("You wrote: %i %i %i %i", minx, x, y, z);
}
Try deleting them with:
npm config delete proxy
npm config delete https-proxy
i resolve this problem in this way, later i will improve the code
protected Void doInBackground(byte[]... data) {

outFile.setExecutable(true, false);
outFile.setWritable(true, false);

outStream.write(data[0]);
outStream.flush();
outStream.close();
InputStream in = new FileInputStream(context.getFilesDir()+"image.jpg");

So when you want to set a value, you don't need "Set"; otherwise, if you are referring to an object, e.g. worksheet/range etc., you need using "Set".

I place the @Transactional
on the @Service
layer and set rollbackFor
any exception and readOnly
to optimize the transaction further.
By default @Transactional
will only look for RuntimeException
(Unchecked Exceptions), by setting rollback to Exception.class
(Checked Exceptions) it will rollback for any exception.
@Transactional(readOnly = false, rollbackFor = Exception.class)
To generate a random number between min and max, use:
int randNum = rand()%(max-min + 1) + min;
(Includes max and min)
Meteor is a framework built ontop of node.js. It uses node.js to deploy but has several differences.
The key being it uses its own packaging system instead of node's module based system. It makes it easy to make web applications using Node. Node can be used for a variety of things and on its own is terrible at serving up dynamic web content. Meteor's libraries make all of this easy.
mylist = ['a', 'ab', 'abc']

The question has already been answered, but I thought I'd add an answer with more precise terminology and references to the C++ standard.
Two things are going on here, array parameters being adjusted to pointer parameters, and array arguments being converted to pointer arguments. These are two quite different mechanisms, the first is an adjustment to the actual type of the parameter, whereas the other is a standard conversion which introduces a temporary pointer to the first element.
Adjustments to your function declaration:
After determining the type of each parameter, any parameter of type “array of T” (...) is adjusted to be “pointer to T”.
So int arg[]
is adjusted to be int* arg
.
Conversion of your function argument:
An lvalue or rvalue of type “array of N T” or “array of unknown bound of T” can be converted to a prvalue of type “pointer to T”. The temporary materialization conversion is applied. The result is a pointer to the first element of the array.
So in printarray(firstarray, 3);
, the lvalue firstarray
of type "array of 3 int" is converted to a prvalue (temporary) of type "pointer to int", pointing to the first element.
There are some things to change in your code:
0x7634706d
: out = cv2.VideoWriter('output.mp4',0x7634706d , 20.0, (640,480))
If you use Windows, there some shortcuts, while devtools are opened:
Pressing Ctrl+Shift+D will dock all devtools to left, right, bottom in turn.
Press Ctrl+Shift+F if your JS console disappeared, and you want it docked back to bottom within dev tools.
<edit>
Just noticed you said mod_rewrite.s instead of mod_rewrite.so - hope that's a typo in your question and not in the httpd.conf file! :)
</edit>
I'm more used to using Apache on Linux, but I had to do this the other day.
First off, take a look in your Apache install directory. (I'll be assuming you installed it to "C:\Program Files" here)
Take a look in the folder: "C:\Program Files\Apache Software Foundation\Apache2.2\modules" and make sure that there's a file called mod_rewrite.so in there. (It should be, it's provided as part of the default install.
Next, open up "C:\Program Files\Apache Software Foundation\Apache2.2\conf" and open httpd.conf. Make sure the line:
#LoadModule rewrite_module modules/mod_rewrite.so
is uncommented:
LoadModule rewrite_module modules/mod_rewrite.so
Also, if you want to enable the RewriteEngine by default, you might want to add something like
<IfModule mod_rewrite>
RewriteEngine On
</IfModule>
to the end of your httpd.conf file.
If not, make sure you specify
RewriteEngine On
somewhere in your .htaccess file.
If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:
var vm = new Vue({
data: {
list: [
{name: 'obj1 to watch'},
{name: 'obj2 to watch'},
],
},
methods: {
handleChange (newVal, oldVal) {
// Handle changes here!
// NOTE: For mutated objects, newVal and oldVal will be identical.
console.log(newVal);
},
},
created () {
this.list.forEach((val) => {
this.$watch(() => val, this.handleChange, {deep: true});
});
},
});
If your list isn't populated straight away (like in the original question), you can move the logic out of created
to wherever needed, e.g. inside the .then()
block.
If your list itself updates to have new or removed items, I've developed a useful pattern that "shallow" watches the list itself, and dynamically watches/unwatches items as the list changes:
// NOTE: This example uses Lodash (_.differenceBy and _.pull) to compare lists
// and remove list items. The same result could be achieved with lots of
// list.indexOf(...) if you need to avoid external libraries.
var vm = new Vue({
data: {
list: [
{name: 'obj1 to watch'},
{name: 'obj2 to watch'},
],
watchTracker: [],
},
methods: {
handleChange (newVal, oldVal) {
// Handle changes here!
console.log(newVal);
},
updateWatchers () {
// Helper function for comparing list items to the "watchTracker".
const getItem = (val) => val.item || val;
// Items that aren't already watched: watch and add to watched list.
_.differenceBy(this.list, this.watchTracker, getItem).forEach((item) => {
const unwatch = this.$watch(() => item, this.handleChange, {deep: true});
this.watchTracker.push({ item: item, unwatch: unwatch });
// Uncomment below if adding a new item to the list should count as a "change".
// this.handleChange(item);
});
// Items that no longer exist: unwatch and remove from the watched list.
_.differenceBy(this.watchTracker, this.list, getItem).forEach((watchObj) => {
watchObj.unwatch();
_.pull(this.watchTracker, watchObj);
// Optionally add any further cleanup in here for when items are removed.
});
},
},
watch: {
list () {
return this.updateWatchers();
},
},
created () {
return this.updateWatchers();
},
});
A simple approach is to output as html, which pandas does out of the box:
df.to_html('temp.html')
Besides all of the (well-explained) answers, there hasn't been the following mentioned and I visit this Q&A quite often.
In a nutshell; MySQL thinks you want to do math on its own table/column and interprets hyphens such as "e-mail" as e
minus mail
.
Disclaimer: So I thought I would add this as an "FYI" type of answer for those who are completely new to working with databases and who may not understand the technical terms described already.
When you declare a variable, you need to declare its type - in this case: int
. Also you've put a random comma in the while
loop. It probably worth looking up the syntax for Java and consider using a IDE that picks up on these kind of mistakes. You probably want something like this:
int [] numbers = { 1, 2, 3, 4, 5 ,6, 7, 8, 9 , 10 };
int sum = 0;
for(int i = 0; i < numbers.length; i++){
sum += numbers[i];
}
System.out.println("The sum is: " + sum);
Finally it worked for me.
<select ng-init="mybasketModel = basket[0]" ng-model="mybasketModel">
<option ng-repeat="item in basket" ng-selected="$first">{{item}}</option>
</select>
So, I hear this works:
Data$X1<-as.character(Data$X1)
Data$GEOID<-as.character(Data$BLKIDFP00)
Data<-within(Data,X1<-ifelse(is.na(Data$X1),GEOID,Data$X2))
But I admit I have only intermittent luck with it.
The {{variable}}
is substituted directly into the HTML. Do a view source; it isn't a "variable" or anything like it. It's just rendered text.
Having said that, you can put this kind of substitution into your JavaScript.
<script type="text/javascript">
var a = "{{someDjangoVariable}}";
</script>
This gives you "dynamic" javascript.
i think the setTimeout function that you write is not being run. if you use jquery, you can make it run correctly by doing this :
function alertMsg() {
//your func
}
$(document).ready(function() {
setTimeout(alertMsg,3000);
// the function you called by setTimeout must not be a string.
});
A public field is not worse than a getter/setter pair that does nothing except returning the field and assigning to it. First, it's clear that (in most languages) there is no functional difference. Any difference must be in other factors, like maintainability or readability.
An oft-mentioned advantage of getter/setter pairs, isn't. There's this claim that you can change the implementation and your clients don't have to be recompiled. Supposedly, setters let you add functionality like validation later on and your clients don't even need to know about it. However, adding validation to a setter is a change to its preconditions, a violation of the previous contract, which was, quite simply, "you can put anything in here, and you can get that same thing later from the getter".
So, now that you broke the contract, changing every file in the codebase is something you should want to do, not avoid. If you avoid it you're making the assumption that all the code assumed the contract for those methods was different.
If that should not have been the contract, then the interface was allowing clients to put the object in invalid states. That's the exact opposite of encapsulation If that field could not really be set to anything from the start, why wasn't the validation there from the start?
This same argument applies to other supposed advantages of these pass-through getter/setter pairs: if you later decide to change the value being set, you're breaking the contract. If you override the default functionality in a derived class, in a way beyond a few harmless modifications (like logging or other non-observable behaviour), you're breaking the contract of the base class. That is a violation of the Liskov Substitutability Principle, which is seen as one of the tenets of OO.
If a class has these dumb getters and setters for every field, then it is a class that has no invariants whatsoever, no contract. Is that really object-oriented design? If all the class has is those getters and setters, it's just a dumb data holder, and dumb data holders should look like dumb data holders:
class Foo {
public:
int DaysLeft;
int ContestantNumber;
};
Adding pass-through getter/setter pairs to such a class adds no value. Other classes should provide meaningful operations, not just operations that fields already provide. That's how you can define and maintain useful invariants.
Client: "What can I do with an object of this class?"
Designer: "You can read and write several variables."
Client: "Oh... cool, I guess?"
There are reasons to use getters and setters, but if those reasons don't exist, making getter/setter pairs in the name of false encapsulation gods is not a good thing. Valid reasons to make getters or setters include the things often mentioned as the potential changes you can make later, like validation or different internal representations. Or maybe the value should be readable by clients but not writable (for example, reading the size of a dictionary), so a simple getter is a nice choice. But those reasons should be there when you make the choice, and not just as a potential thing you may want later. This is an instance of YAGNI (You Ain't Gonna Need It).

I wrote an article on topis how to [manually install curl on debian linu][1]x.
[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:
And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.
If it is possible to change the sequence of the lines you could do:
^(.*\r?\n)\1+
How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n)
and captures the line in \1
then it continues and tries to find \1
one or more times (+
) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.
The \r?\n
should deal nicely with Windows and Unix lineendings.
If you really want constants, not just variables looking like constants, the standard way to do it is to use immutable dictionaries. Unfortunately it's not built-in yet, so you have to use third party recipes (like this one or that one).
This:
string clean = Regex.Replace(dirty, "[^a-zA-Z0-9\x20]", String.Empty);
\x20 is ascii hex for 'space' character
you can add more individual characters that you want to be allowed. If you want for example "?" to be ok in the return string add \x3f.
a = ['a1','b2','c3']
b = ['a1','b2','c3']
c = ['b2','a1','c3']
# if you care about order
a == b # True
a == c # False
# if you don't care about order AND duplicates
set(a) == set(b) # True
set(a) == set(c) # True
By casting a
, b
and c
as a set, you remove duplicates and order doesn't count. Comparing sets is also much faster and more efficient than comparing lists.

A process normally has two outputs to screen: stdout (standard out), and stderr (standard error).
Normally informational messages go to sdout
, and errors and alerts go to stderr
.
You can turn off stdout
for a command by doing
MyCommand >/dev/null
and turn off stderr
by doing:
MyCommand 2>/dev/null
If you want both off, you can do:
MyCommand 2>&1 >/dev/null
The 2>&1
says send stderr to the same place as stdout.
Use this ^[a-zA-Z0-9_]*$

First, you use include_directories()
to tell CMake to add the directory as -I
to the compilation command line. Second, you list the headers in your add_executable()
or add_library()
call.
As an example, if your project's sources are in src
, and you need headers from include
, you could do it like this:
include_directories(include)
add_executable(MyExec
src/main.c
src/other_source.c
include/header1.h
include/header2.h
)
It's Quite easy using Google Distance Matrix service
First step is to activate Distance Matrix service from google API console. it returns distances between a set of locations. And apply this simple function
function initMap() {
var bounds = new google.maps.LatLngBounds;
var markersArray = [];
var origin1 = {lat:23.0203, lng: 72.5562};
//var origin2 = 'Ahmedabad, India';
var destinationA = {lat:23.0436503, lng: 72.55008939999993};
//var destinationB = {lat: 23.2156, lng: 72.6369};
var destinationIcon = 'https://chart.googleapis.com/chart?' +
'chst=d_map_pin_letter&chld=D|FF0000|000000';
var originIcon = 'https://chart.googleapis.com/chart?' +
'chst=d_map_pin_letter&chld=O|FFFF00|000000';
var map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 55.53, lng: 9.4},
zoom: 10
});
var geocoder = new google.maps.Geocoder;
var service = new google.maps.DistanceMatrixService;
service.getDistanceMatrix({
origins: [origin1],
destinations: [destinationA],
travelMode: 'DRIVING',
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, function(response, status) {
if (status !== 'OK') {
alert('Error was: ' + status);
} else {
var originList = response.originAddresses;
var destinationList = response.destinationAddresses;
var outputDiv = document.getElementById('output');
outputDiv.innerHTML = '';
deleteMarkers(markersArray);
var showGeocodedAddressOnMap = function(asDestination) {
var icon = asDestination ? destinationIcon : originIcon;
return function(results, status) {
if (status === 'OK') {
map.fitBounds(bounds.extend(results[0].geometry.location));
markersArray.push(new google.maps.Marker({
map: map,
position: results[0].geometry.location,
icon: icon
}));
} else {
alert('Geocode was not successful due to: ' + status);
}
};
};
for (var i = 0; i < originList.length; i++) {
var results = response.rows[i].elements;
geocoder.geocode({'address': originList[i]},
showGeocodedAddressOnMap(false));
for (var j = 0; j < results.length; j++) {
geocoder.geocode({'address': destinationList[j]},
showGeocodedAddressOnMap(true));
//outputDiv.innerHTML += originList[i] + ' to ' + destinationList[j] + ': ' + results[j].distance.text + ' in ' + results[j].duration.text + '<br>';
outputDiv.innerHTML += results[j].distance.text + '<br>';
}
}
}
});
}
Where origin1 is your location and destinationA is destindation location.you can add above two or more data.
Rad Full Documentation with an example
To quote the specifications:
The docstring of a script (a stand-alone program) should be usable as its "usage" message, printed when the script is invoked with incorrect or missing arguments (or perhaps with a "-h" option, for "help"). Such a docstring should document the script's function and command line syntax, environment variables, and files. Usage messages can be fairly elaborate (several screens full) and should be sufficient for a new user to use the command properly, as well as a complete quick reference to all options and arguments for the sophisticated user.
The docstring for a module should generally list the classes, exceptions and functions (and any other objects) that are exported by the module, with a one-line summary of each. (These summaries generally give less detail than the summary line in the object's docstring.) The docstring for a package (i.e., the docstring of the package's
__init__.py
module) should also list the modules and subpackages exported by the package.The docstring for a class should summarize its behavior and list the public methods and instance variables. If the class is intended to be subclassed, and has an additional interface for subclasses, this interface should be listed separately (in the docstring). The class constructor should be documented in the docstring for its
__init__
method. Individual methods should be documented by their own docstring.
The docstring of a function or method is a phrase ending in a period. It prescribes the function or method's effect as a command ("Do this", "Return that"), not as a description; e.g. don't write "Returns the pathname ...". A multiline-docstring for a function or method should summarize its behavior and document its arguments, return value(s), side effects, exceptions raised, and restrictions on when it can be called (all if applicable). Optional arguments should be indicated. It should be documented whether keyword arguments are part of the interface.
Yes, Mid
.
Dim sub_str
sub_str = Mid(source_str, 10, 5)
The first parameter is the source string, the second is the start index, and the third is the length.
@bobobobo: Note that VBScript strings are 1-based, not 0-based. Passing 0 as an argument to Mid
results in "invalid procedure call or argument Mid".
Your method needs to return a ActionResult
type:
public ActionResult Index()
{
//All we want to do is redirect to the class selection page
return RedirectToAction("SelectClasses", "Registration");
}
Pawel Sawicz .NET blog has a real good explanation and example code, explaining how to call the library;
GET:
var client = new RestClient("192.168.0.1");
var request = new RestRequest("api/item/", Method.GET);
var queryResult = client.Execute<List<Items>>(request).Data;
POST:
var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/", Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddBody(new Item
{
ItemName = someName,
Price = 19.99
});
client.Execute(request);
DELETE:
var item = new Item(){//body};
var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/{id}", Method.DELETE);
request.AddParameter("id", idItem);
client.Execute(request)
The RestSharp GitHub page has quite an exhaustive sample halfway down the page. To get started install the RestSharp NuGet package in your project, then include the necessary namespace references in your code, then above code should work (possibly negating your need for a full example application).

I think "new" adds clarity to the code. And clarity is worth everything. Good to know there are pitfalls, but avoiding them by avoiding clarity doesn't seem like the way for me.
Try this:
INSERT INTO newTable SELECT * FROM initial_Table
In your $CATALINA_BASE/conf/context.xml
add block below before </Context>
<Resources cachingAllowed="true" cacheMaxSize="100000" />

The following query i have used in sql-server 2008, it may be help you.
For add day DATEADD(DAY,20,GETDATE())
*20 is the day quantity
I think the answer is much easier.
To hide the tab you just can use the way you already tried or adressing the TabPage itself.
TabControl1.TabPages.Remove(TabPage1) 'Could be male
TabControl1.TabPages.Remove(TabPage2) 'Could be female
a.s.o.
Removing the TabPage does not destroy it and the controls on it. To show the corresponding tab again just use the following code
TabControl1.TabPages.Insert(0, TabPage1) 'Show male
TabControl1.TabPages.Insert(1, TabPage2) 'Show female
One way would be to just escape the quotes properly:
<input type="button" value="click" id="mybtn"
onclick="myfunction('/myController/myAction',
'myfuncionOnOK(\'/myController2/myAction2\',
\'myParameter2\');',
'myfuncionOnCancel(\'/myController3/myAction3\',
\'myParameter3\');');">
In this case, though, I think a better way to handle this would be to wrap the two handlers in anonymous functions:
<input type="button" value="click" id="mybtn"
onclick="myfunction('/myController/myAction',
function() { myfuncionOnOK('/myController2/myAction2',
'myParameter2'); },
function() { myfuncionOnCancel('/myController3/myAction3',
'myParameter3'); });">
And then, you could call them from within myfunction
like this:
function myfunction(url, onOK, onCancel)
{
// Do whatever myfunction would normally do...
if (okClicked)
{
onOK();
}
if (cancelClicked)
{
onCancel();
}
}
That's probably not what myfunction
would actually look like, but you get the general idea. The point is, if you use anonymous functions, you have a lot more flexibility, and you keep your code a lot cleaner as well.
For MAC user, add this line into your Default Settings
File path is: /Users/USER_NAME/Library/Application Support/Code/User/settings.json
"tslint.autoFixOnSave": true
Sample of the file would be:
{
"window.zoomLevel": 0,
"workbench.iconTheme": "vscode-icons",
"typescript.check.tscVersion": false,
"vsicons.projectDetection.disableDetect": true,
"typescript.updateImportsOnFileMove.enabled": "always",
"eslint.autoFixOnSave": true,
"tslint.autoFixOnSave": true
}
In Sequelize version 5 you might also can use this way (full use Operator Sequelize) :
var condition =
{
[Op.or]: [
{
LastName: {
[Op.eq]: "Doe"
},
},
{
FirstName: {
[Op.or]: ["John", "Jane"]
}
},
{
Age:{
[Op.gt]: 18
}
}
]
}
And then, you must include this :
const Op = require('Sequelize').Op
and pass it in :
Student.findAll(condition)
.success(function(students){
//
})
It could beautifully generate SQL like this :
"SELECT * FROM Student WHERE LastName='Doe' OR FirstName in ("John","Jane") OR Age>18"
Given an email address like...
[email protected]
The length limits are as follows:
256
characters maximum.64
character maximum.254
characters maximum.SMTP originally defined what a path was in RFC821, published August 1982, which is an official Internet Standard (most RFC's are only proposals). To quote it...
...a reverse-path, specifies who the mail is from.
...a forward-path, which specifies who the mail is to.
RFC2821, published in April 2001, is the Obsoleted Standard that defined our present maximum values for local-parts, domains, and paths. A new Draft Standard, RFC5321, published in October 2008, keeps the same limits. In between these two dates, RFC3696 was published, on February 2004. It mistakenly cites the maximum email address limit as 320
-characters, but this document is "Informational" only, and states: "This memo provides information for the Internet community. It does not specify an Internet standard of any kind." So, we can disregard it.
To quote RFC2821, the modern, accepted standard as confirmed in RFC5321...
4.5.3.1.1. Local-part
The maximum total length of a user name or other local-part is 64 characters.
4.5.3.1.2. Domain
The maximum total length of a domain name or number is 255 characters.
4.5.3.1.3. Path
The maximum total length of a reverse-path or forward-path is 256 characters (including the punctuation and element separators).
You'll notice that I indicate a domain maximum of 254 and the RFC indicates a domain maximum of 255. It's a matter of simple arithmetic. A 255-character domain, plus the "@" sign, is a 256-character path, which is the max path length. An empty or blank name is invalid, though, so the domain actually has a maximum of 254.
INSERT INTO def (field_1, field_2, field3)

PostgreSQL does not define round(double precision, integer)
. For reasons @Mike Sherrill 'Cat Recall' explains in the comments, the version of round that takes a precision is only available for numeric
.
regress=> SELECT round( float8 '3.1415927', 2 );
ERROR: function round(double precision, integer) does not exist
regress=> \df *round*
List of functions
Schema | Name | Result data type | Argument data types | Type
------------+--------+------------------+---------------------+--------
pg_catalog | dround | double precision | double precision | normal
pg_catalog | round | double precision | double precision | normal
pg_catalog | round | numeric | numeric | normal
pg_catalog | round | numeric | numeric, integer | normal
(4 rows)
regress=> SELECT round( CAST(float8 '3.1415927' as numeric), 2);
round
-------
3.14
(1 row)
(In the above, note that float8
is just a shorthand alias for double precision
. You can see that PostgreSQL is expanding it in the output).
You must cast the value to be rounded to numeric
to use the two-argument form of round
. Just append ::numeric
for the shorthand cast, like round(val::numeric,2)
.
If you're formatting for display to the user, don't use round
. Use to_char
(see: data type formatting functions in the manual), which lets you specify a format and gives you a text
result that isn't affected by whatever weirdness your client language might do with numeric
values. For example:
regress=> SELECT to_char(float8 '3.1415927', 'FM999999999.00');
to_char
---------------
3.14
(1 row)
to_char
will round numbers for you as part of formatting. The FM
prefix tells to_char
that you don't want any padding with leading spaces.

First Create Bitmap Image
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.image);
now set bitmap in Notification Builder Icon....
Notification.Builder.setLargeIcon(bmp);
I know that its bit old Q but if u get here by searching a solution so i got a nice one via jquery
jQuery('a[target^="_new"]').click(function() {
var width = window.innerWidth * 0.66 ;
// define the height in
var height = width * window.innerHeight / window.innerWidth ;
// Ratio the hight to the width as the user screen ratio
window.open(this.href , 'newwindow', 'width=' + width + ', height=' + height + ', top=' + ((window.innerHeight - height) / 2) + ', left=' + ((window.innerWidth - width) / 2));
});
it will open all the <a target="_new">
in a new window
EDIT:
1st, I did some little changes in the original code now it open the new window perfectly followed the user screen ratio (for landscape desktops)
but, I would like to recommend you to use the following code that open the link in new tab if you in mobile (thanks to zvona answer in other question):
jQuery('a[target^="_new"]').click(function() {
return openWindow(this.href);
}
function openWindow(url) {
if (window.innerWidth <= 640) {
// if width is smaller then 640px, create a temporary a elm that will open the link in new tab
var a = document.createElement('a');
a.setAttribute("href", url);
a.setAttribute("target", "_blank");
var dispatch = document.createEvent("HTMLEvents");
dispatch.initEvent("click", true, true);
a.dispatchEvent(dispatch);
}
else {
var width = window.innerWidth * 0.66 ;
// define the height in
var height = width * window.innerHeight / window.innerWidth ;
// Ratio the hight to the width as the user screen ratio
window.open(url , 'newwindow', 'width=' + width + ', height=' + height + ', top=' + ((window.innerHeight - height) / 2) + ', left=' + ((window.innerWidth - width) / 2));
}
return false;
}
The answers are not making it clear:
Use this.$refs.someName
, but, in order to use it, you must add ref="someName"
in the parent.
See demo below.
new Vue({_x000D_
el: '#app',_x000D_
mounted: function() {_x000D_
var childSpanClassAttr = this.$refs.someName.getAttribute('class');_x000D_
_x000D_
console.log('<span> was declared with "class" attr -->', childSpanClassAttr);_x000D_
}_x000D_
})
_x000D_

<div id="app">_x000D_
Parent._x000D_
<span ref="someName" class="abc jkl xyz">Child Span</span>_x000D_
</div>
_x000D_
$refs
and v-for
Notice that when used in conjunction with v-for
, the this.$refs.someName
will be an array:
new Vue({_x000D_
el: '#app',_x000D_
data: {_x000D_
ages: [11, 22, 33]_x000D_
},_x000D_
mounted: function() {_x000D_
console.log("<span> one's text....:", this.$refs.mySpan[0].innerText);_x000D_
console.log("<span> two's text....:", this.$refs.mySpan[1].innerText);_x000D_
console.log("<span> three's text..:", this.$refs.mySpan[2].innerText);_x000D_
}_x000D_
})
_x000D_
span { display: inline-block; border: 1px solid red; }
_x000D_
<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>_x000D_
_x000D_
<div id="app">_x000D_

Try this -
<?php
date_default_timezone_set('Asia/Kolkata');
$timestamp = time();
$date_time = date("d-m-Y (D) H:i:s", $timestamp);
echo "Current date and local time on this server is $date_time";
?>
If i understand what you want:
'email' => 'required|email|unique:users,email_address,'. $id .''
In model update method, for exemple, should receive the $id with parameter.
Sorry my bad english.
You could create a user form:
That's not possible.
The alternative is using reflection:
Class.forName("SomeClass").getMethod("someMethod").invoke(null);
Mono comes with a wrapper, use theirs!
https://github.com/mono/mono/tree/master/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0 gives code to wrap the actual SQLite dll ( http://www.sqlite.org/sqlite-shell-win32-x86-3071300.zip found on the download page http://www.sqlite.org/download.html/ ) in a .net friendly way. It works on Linux or Windows.
This seems the thinnest of all worlds, minimizing your dependence on third party libraries. If I had to do this project from scratch, this is the way I would do it.
IF you want to select object with minimum or maximum property value. another way is to use Implementing IComparable.
public struct Money : IComparable<Money>
{
public Money(decimal value) : this() { Value = value; }
public decimal Value { get; private set; }
public int CompareTo(Money other) { return Value.CompareTo(other.Value); }
}
Max Implementation will be.
var amounts = new List<Money> { new Money(20), new Money(10) };
Money maxAmount = amounts.Max();
Min Implementation will be.
var amounts = new List<Money> { new Money(20), new Money(10) };
Money maxAmount = amounts.Min();
In this way, you can compare any object and get the Max and Min while returning the object type.
Hope This will help someone.
Use StringBuilder instead of StringBuffer, because it is faster than StringBuffer.
String[] strArr = {"1", "2", "3"};
StringBuilder strBuilder = new StringBuilder();
for (int i = 0; i < strArr.length; i++) {
strBuilder.append(strArr[i]);
}
String newString = strBuilder.toString();
Here's why this is a better solution to using string concatenation: When you concatenate 2 strings, a new string object is created and character by character copy is performed.
Effectively meaning that the code complexity would be the order of the squared of the size of your array!
(1+2+3+ ... n
which is the number of characters copied per iteration).
StringBuilder would do the 'copying to a string' only once in this case reducing the complexity to O(n)
.
I'm not answering why it is so, but only wanted to show a way around that limitation in SQL Server by using CROSS APPLY
to create the alias. You then use it in the GROUP BY
clause, like so:
SELECT
itemName as ItemName,
FirstLetter,
Count(itemName)
FROM table1
CROSS APPLY (SELECT substring(itemName, 1,1) as FirstLetter) Alias
GROUP BY itemName, FirstLetter
Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.
<input class="form-control" type="email" required="" placeholder="username"
oninvalid="this.setCustomValidity('Please Enter valid email')"
oninput="setCustomValidity('')"></input>
Here,
this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field
oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.

However having a simple git pull
as a deployment process is usually a bad idea and should be avoided in favor of a real deployment script.
My problem was similar to @Toddarooski 's, except that the module I had, under the "Dependencies" tab, had no SDK listed. I right clicked on 'SDK', picked edit from the drop down menu, and selected my Python SDK. That did the trick.
I had trouble with SQLite3, nStore and Alfred.
What works for me is node-dirty:
path = "#{__dirname}/data/messages.json"
messages = db path
message = 'text': 'Lorem ipsum dolor sit...'
messages.on "load", ->
messages.set 'my-unique-key', message, ->
console.log messages.get('my-unique-key').text
messages.forEach (key, value) ->
console.log "Found key: #{key}, val: %j", value
messages.on "drain", ->
console.log "Saved to #{path}"
I had a similar issue recently while working on recursion and nested lists. I declared:
print(r_sum([1,2,3[1,2,3],]))
instead of
print(r_sum([1,2,3,[1,2,3],]))
Note the comma after the number 3
Application.CutCopyMode = False
There are several ways to go about this, it depends what your purpose is, if you just want to execute the function as well and in the same context, you can use .apply()
:
function init(){
doSomething();
}
function myFunc(){
init.apply(this, arguments);
doSomethingHereToo();
}
If you want to replace it with a newer init
, it'd look like this:
function init(){
doSomething();
}
//anytime later
var old_init = init;
init = function() {
old_init.apply(this, arguments);
doSomethingHereToo();
};
I know this has a few answers, but maybe this will help someone. I have used a relatively simple solution when I needed to get a Fragment
from my ViewPager
. In your Activity
or Fragment
holding the ViewPager
, you can use this code to cycle through every Fragment
it holds.
FragmentPagerAdapter fragmentPagerAdapter = (FragmentPagerAdapter) mViewPager.getAdapter();
for(int i = 0; i < fragmentPagerAdapter.getCount(); i++) {
Fragment viewPagerFragment = fragmentPagerAdapter.getItem(i);
if(viewPagerFragment != null) {
// Do something with your Fragment
// Check viewPagerFragment.isResumed() if you intend on interacting with any views.
}
}
If you know the position of your Fragment
in the ViewPager
, you can just call getItem(knownPosition)
.
If you don't know the position of your Fragment
in the ViewPager
, you can have your children Fragments
implement an interface with a method like getUniqueId()
, and use that to differentiate them. Or you can cycle through all Fragments
and check the class type, such as if(viewPagerFragment instanceof FragmentClassYouWant)
!!! EDIT !!!
I have discovered that getItem
only gets called by a FragmentPagerAdapter
when each Fragment
needs to be created the first time, after that, it appears the the Fragments
are recycled using the FragmentManager
. This way, many implementations of FragmentPagerAdapter
create new Fragment
s in getItem
. Using my above method, this means we will create new Fragment
s each time getItem
is called as we go through all the items in the FragmentPagerAdapter
. Due to this, I have found a better approach, using the FragmentManager
to get each Fragment
instead (using the accepted answer). This is a more complete solution, and has been working well for me.
FragmentPagerAdapter fragmentPagerAdapter = (FragmentPagerAdapter) mViewPager.getAdapter();
for(int i = 0; i < fragmentPagerAdapter.getCount(); i++) {
String name = makeFragmentName(mViewPager.getId(), i);
Fragment viewPagerFragment = getChildFragmentManager().findFragmentByTag(name);
// OR Fragment viewPagerFragment = getFragmentManager().findFragmentByTag(name);
if(viewPagerFragment != null) {
// Do something with your Fragment
if (viewPagerFragment.isResumed()) {
// Interact with any views/data that must be alive
}
else {
// Flag something for update later, when this viewPagerFragment
// returns to onResume
}
}
}
And you will need this method.
private static String makeFragmentName(int viewId, int position) {
return "android:switcher:" + viewId + ":" + position;
}
Rather than WNetUseConnection, I would recommend NetUseAdd. WNetUseConnection is a legacy function that's been superceded by WNetUseConnection2 and WNetUseConnection3, but all of those functions create a network device that's visible in Windows Explorer. NetUseAdd is the equivalent of calling net use in a DOS prompt to authenticate on a remote computer.
If you call NetUseAdd then subsequent attempts to access the directory should succeed.
If you just want to get the current UNIX timestamp I'd just use time()
$timestamp = time();
If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option. The wizard exports the complete result set regardless of what you selected
You'll need to cast it:
export type Fruit = "Orange" | "Apple" | "Banana";
let myString: string = "Banana";
let myFruit: Fruit = myString as Fruit;
Also notice that when using string literals you need to use only one |
As mentioned in the other answer by @Simon_Weaver, it's now possible to assert it to const
:
let fruit = "Banana" as const;
I can give an example commonly seen in project.
Here, option --no-ff
(i.e. true merge) creates a new commit with multiple parents, and provides a better history tracking. Otherwise, --ff
(i.e. fast-forward merge) is by default.
$ git checkout master
$ git checkout -b newFeature
$ ...
$ git commit -m 'work from day 1'
$ ...
$ git commit -m 'work from day 2'
$ ...
$ git commit -m 'finish the feature'
$ git checkout master
$ git merge --no-ff newFeature -m 'add new feature'
$ git log
// something like below
commit 'add new feature' // => commit created at merge with proper message
commit 'finish the feature'
commit 'work from day 2'
commit 'work from day 1'
$ gitk // => see details with graph
$ git checkout -b anotherFeature // => create a new branch (*)
$ ...
$ git commit -m 'work from day 3'
$ ...
$ git commit -m 'work from day 4'
$ ...
$ git commit -m 'finish another feature'
$ git checkout master
$ git merge anotherFeature // --ff is by default, message will be ignored
$ git log
// something like below
commit 'work from day 4'
commit 'work from day 3'
commit 'add new feature'
commit 'finish the feature'
commit ...
$ gitk // => see details with graph
(*) Note that here if the newFeature
branch is re-used, instead of creating a new branch, git will have to do a --no-ff
merge anyway. This means fast forward merge is not always eligible.

You can access the id after calling the persist method of the entity manager.
$widgetEntity = new WidgetEntity();
$entityManager->persist($widgetEntity);
$entityManager->flush();
$widgetEntity->getId();
You do need to flush in order to get this id.
Syntax Error Fix: Added semi-colon after $entityManager->flush() is called.
You would think that using '.\' as the path means that it's the invocation path. But not all the time. Example, if you use it inside a job ScriptBlock. In which case, it might point to %profile%\Documents.
Arrays are enumerable, so your foo
already is an IEnumerable<byte>
itself.
Simply use LINQ sequence methods like Take()
to get what you want out of it (don't forget to include the Linq
namespace with using System.Linq;
):
byte[] foo = new byte[4096];
var bar = foo.Take(41);
If you really need an array from any IEnumerable<byte>
value, you could use the ToArray()
method for that. That does not seem to be the case here.

<?php
$con=mysqli_connect("localhost","root","YOUR_PHPMYADMIN_PASSWORD","hrmwaitrose");
// Check connection
if (mysqli_connect_errno())

echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

You can similarly echo
it inside your table
<?php
echo "<table>";
while($row = mysqli_fetch_array($result))
{
echo "<tr><td>" . $row['FirstName'] . "</td><td> " . $row['LastName'] . "</td></tr>"; //these are the fields that you have stored in your database table employee
}
echo "</table>";
mysqli_close($con);
?>

Just to update this question for mod_security 2.7.0+ - they turned off the ability to mitigate modsec via htaccess unless you compile it with the --enable-htaccess-config
flag. Most hosts do not use this compiler option since it allows too lax security. Instead, vhosts in httpd.conf are your go-to option for controlling modsec.
Even if you do compile modsec with htaccess mitigation, there are less directives available. SecRuleEngine
can no longer be used there for example. Here is a list that is available to use by default in htaccess if allowed (keep in mind a host may further limit this list with AllowOverride
):
- SecAction
- SecRule
- SecRuleRemoveByMsg
- SecRuleRemoveByTag
- SecRuleRemoveById
- SecRuleUpdateActionById
- SecRuleUpdateTargetById
- SecRuleUpdateTargetByTag
- SecRuleUpdateTargetByMsg
More info on the official modsec wiki
As an additional note for 2.x users: the IfModule
should now look for mod_security2.c
instead of the older mod_security.c
I'd prefer to use [:punct:]
for that. Also, a-zA-Z09-9
could be just [:alnum:]
:
[[ $TEST =~ ^[[:alnum:][:blank:][:punct:]]+$ ]]
$(element).on("click mousedown mouseup focus blur keydown change",function(e){
console.log(e);
});
That will get you a lot (but not all) of the information on if an event is fired... other than manually coding it like this, I can't think of any other way to do that.
A Subject
or Observable
doesn't have a current value. When a value is emitted, it is passed to subscribers and the Observable
is done with it.
If you want to have a current value, use BehaviorSubject
which is designed for exactly that purpose. BehaviorSubject
keeps the last emitted value and emits it immediately to new subscribers.
It also has a method getValue()
to get the current value.
Without the need to install the grep variant pcregrep, you can do multiline search with grep.
$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c
Explanation:
-P
activate perl-regexp for grep (a powerful extension of regular expressions)
-z
suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.
-o
print only matching. Because we're using -z
, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.
In regexp:
(?s)
activate PCRE_DOTALL
, which means that .
finds any character or newline
\N
find anything except newline, even with PCRE_DOTALL
activated
.*?
find .
in non-greedy mode, that is, stops as soon as possible.
^
find start of line
\1
backreference to the first group (\s*
). This is a try to find the same indentation of method.
As you can imagine, this search prints the main method in a C (*.c
) source file.
If you need the same rows but just a random sample then,
import random
new_array = random.sample(old_array,x)
Here x, has to be an 'int' defining the number of rows you want to randomly pick.
