There is now a HDF5 based clone of pickle
called hickle
!
https://github.com/telegraphic/hickle
import hickle as hkl
data = { 'name' : 'test', 'data_arr' : [1, 2, 3, 4] }
# Dump data to file
hkl.dump( data, 'new_data_file.hkl' )
# Load data from file
data2 = hkl.load( 'new_data_file.hkl' )
print( data == data2 )
EDIT:
There also is the possibility to "pickle" directly into a compressed archive by doing:
import pickle, gzip, lzma, bz2
pickle.dump( data, gzip.open( 'data.pkl.gz', 'wb' ) )
pickle.dump( data, lzma.open( 'data.pkl.lzma', 'wb' ) )
pickle.dump( data, bz2.open( 'data.pkl.bz2', 'wb' ) )

Very simple, no library required:
var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);
or you might prefer:
var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);
Some browsers will treat two digit years as being in the 20th century, so that:
new Date(14, 0, 1);
gives 1 January, 1914. To avoid that, create a Date then set its values using setFullYear:
var date = new Date();
date.setFullYear(14, 0, 1); // 1 January, 14
FireFox + FireBug is very good for this purpose. For IE there's a developer toolbar which I've never used and intend to use so I cannot provide much feedback.
The stack pointer stores the address of the most recent entry that was pushed onto the stack.
To push a value onto the stack, the stack pointer is incremented to point to the next physical memory address, and the new value is copied to that address in memory.
To pop a value from the stack, the value is copied from the address of the stack pointer, and the stack pointer is decremented, pointing it to the next available item in the stack.
The most typical use of a hardware stack is to store the return address of a subroutine call. When the subroutine is finished executing, the return address is popped off the top of the stack and placed in the Program Counter register, causing the processor to resume execution at the next instruction following the call to the subroutine.

I wrote Class Visualizer, which does it. It's free tool which has all the mentioned functionality - I personally use it for the same purposes, as described in this post. For each browsed class it shows 2 instantly generated class diagrams: class relations and class UML view. Class relations diagram allows to traverse through the whole structure. It has full support for annotations and generics plus special support for JPA entities. Works very well with big projects (thousands of classes).
This is because $pjs
is an one-element-array of objects, so first you should access the array element, which is an object and then access its attributes.
echo $pjs[0]->player_name;
Actually dump result that you pasted tells it very clearly.
I don't know what your exact problem is, but if you're receiving XML and want to return JSON (or something) you could also look at JAX-B. This is a standard for marshalling/unmarshalling Java POJO's to XML and/or Json. There are multiple libraries that implement JAX-B, for example Apache's CXF.
I just wanted to answer something new for this question - J2V8
.
Author Ian Bull says "Rhino and Nashorn are two common JavaScript runtimes, but these did not meet our requirements in a number of areas:
Neither support ‘Primitives‘. All interactions with these platforms require wrapper classes such as Integer, Double or Boolean. Nashorn is not supported on Android. Rhino compiler optimizations are not supported on Android. Neither engines support remote debugging on Android.""
Here is the solution.
The HTML:
<table cellspacing="0" cellpadding="0">
<tr>
<td>
123
</td>
</tr>
</table>
The CSS:
table {
border-spacing:0;
border-collapse:collapse;
}
Hope this helps.
EDIT
td, th {padding:0}
HTML:
<div>
<img src='' class='class' />
<img src='' class='class' />
<img src='' class='class' />
</div>
JavaScript:
var numItems = $('.class').length;
alert(numItems);
According to MDN: Determining the dimensions of elements
offsetWidth
and offsetHeight
return the "total amount of space an element occupies, including the width of the visible content, scrollbars (if any), padding, and border"
clientWidth
and clientHeight
return "how much space the actual displayed content takes up, including padding but not including the border, margins, or scrollbars"
scrollWidth
and scrollHeight
return the "actual size of the content, regardless of how much of it is currently visible"
So it depends on whether the measured content is expected to be out of the current viewable area.
For browser compatibility you can use this code. This method returns browser name and version :
private string GetBrowserNameWithVersion
{
var userAgent = Request.UserAgent;
var browserWithVersion = "";
if (userAgent.IndexOf("Edge") > -1)
{
//Edge
browserWithVersion = "Edge Browser Version : " + userAgent.Split(new string[] { "Edge/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Chrome") > -1)
{
//Chrome
browserWithVersion = "Chrome Browser Version : " + userAgent.Split(new string[] { "Chrome/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Safari") > -1)
{
//Safari
browserWithVersion = "Safari Browser Version : " + userAgent.Split(new string[] { "Safari/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Firefox") > -1)
{
//Firefox
browserWithVersion = "Firefox Browser Version : " + userAgent.Split(new string[] { "Firefox/" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("rv") > -1)
{
//IE11
browserWithVersion = "Internet Explorer Browser Version : " + userAgent.Split(new string[] { "rv:" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("MSIE") > -1)
{
//IE6-10
browserWithVersion = "Internet Explorer Browser Version : " + userAgent.Split(new string[] { "MSIE" }, StringSplitOptions.None)[1].Split('.')[0];
}
else if (userAgent.IndexOf("Other") > -1)
{
//Other
browserWithVersion = "Other Browser Version : " + userAgent.Split(new string[] { "Other" }, StringSplitOptions.None)[1].Split('.')[0];
}
return browserWithVersion;
}
When we are using Hadoop
in the sense it means we are trying to huge data processing The end goal of the data processing would be to generate content/reports out of it.
So it internally consists of 2 prime activities:
1) Loading Data Processing
2) Generate content and use it for the reporting /etc..
Loading /Data Processing -> Pig would be helpful in it.
This helps as an ETL (We can perform etl operations using pig scripts.).
Once the result is processed we can use hive to generate the reports based on the processed result.
Hive: Its built on top of hdfs for warehouse processing.
We can generate adhoc reports easily using hive from the processed content generated from pig.
Following is working for me on dotnet 1.0.1:
./ourView.cshtml
@Html.Partial(
"_ourPartial.cshtml",
new ViewDataDictionary(this.Vi??ewData) {
{
"hi", "hello"
}
}
);
./_ourPartial.cshtml
<h1>@this.ViewData["hi"]</h1>
Create an EditorTemplate for a specific set of Views (bound by one Controller):
In this example I have a template for a Date, but you can change it to whatever you want.
Here is the code in the Data.cshtml:
@model Nullable<DateTime>
@Html.TextBox("", @Model != null ? String.Format("{0:d}", ((System.DateTime)Model).ToShortDateString()) : "", new { @class = "datefield", type = "date", disabled = "disabled" @readonly = "readonly" })
and in the model:
[DataType(DataType.Date)]
public DateTime? BlahDate { get; set; }
The following example for complex numbers should be self explanatory including the error message at the end

Merging the answers of @Cristian Radu and @Craig Mellon, and the comment from @joel.d, you should do:
NSURL *urlOption1 = [NSURL URLWithString:[@"telprompt://" stringByAppendingString:phone]];
NSURL *urlOption2 = [NSURL URLWithString:[@"tel://" stringByAppendingString:phone]];
NSURL *targetURL = nil;
if ([UIApplication.sharedApplication canOpenURL:urlOption1]) {
targetURL = urlOption1;
} else if ([UIApplication.sharedApplication canOpenURL:urlOption2]) {
targetURL = urlOption2;
}
if (targetURL) {
if (@available(iOS 10.0, *)) {
[UIApplication.sharedApplication openURL:targetURL options:@{} completionHandler:nil];
} else {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
[UIApplication.sharedApplication openURL:targetURL];
#pragma clang diagnostic pop
}
}
This will first try to use the "telprompt://" URL, and if that fails, it will use the "tel://" URL. If both fails, you're trying to place a phone call on an iPad or iPod Touch.
Swift Version :
let phone = mymobileNO.titleLabel.text
let phoneUrl = URL(string: "telprompt://\(phone)"
let phoneFallbackUrl = URL(string: "tel://\(phone)"
if(phoneUrl != nil && UIApplication.shared.canOpenUrl(phoneUrl!)) {
UIApplication.shared.open(phoneUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else if(phoneFallbackUrl != nil && UIApplication.shared.canOpenUrl(phoneFallbackUrl!)) {
UIApplication.shared.open(phoneFallbackUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else {
// Show an error message: Your device can not do phone calls.
}
Maybe your remote repo is in the branch which you want to push. You can try to checkout another branch in your remote machine. I did this, than these error disappeared, and I pushed success to my remote repo. Notice that I use ssh to connect my own server instead of github.com.
It will give consistent behavior for add/remove operations. But while iterating you have to explicitly synchronized. Refer this link
Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process
The above command worked for me even when the following error happens:
Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.

This could also happen when you have to map space separated integers to a list but you enter the integers line by line using the .input()
.
Like for example I was solving this problem on HackerRank Bon-Appetit, and the got the following error while compiling
So instead of giving input to the program line by line try to map the space separated integers into a list using the map()
method.
Please, ckeck this simple example. You can get values in select2 multi.
var values = $('#id-select2-multi').val();
console.log(values);
How do you send the message?
The classes in the System.Net.Mail
namespace (which is probably what you should use) has full support for authentication, either specified in Web.config, or using the SmtpClient.Credentials
property.
First, I'm not certain that you need a second thread to set the shutdown_flag
.
Why not set it directly in the SIGTERM handler?
An alternative is to raise an exception from the SIGTERM
handler, which will be propagated up the stack. Assuming you've got proper exception handling (e.g. with with
/contextmanager
and try: ... finally:
blocks) this should be a fairly graceful shutdown, similar to if you were to Ctrl+C your program.
Example program signals-test.py
:
#!/usr/bin/python
from time import sleep
import signal
import sys
def sigterm_handler(_signo, _stack_frame):
# Raises SystemExit(0):
sys.exit(0)
if sys.argv[1] == "handle_signal":
signal.signal(signal.SIGTERM, sigterm_handler)
try:
print "Hello"
i = 0
while True:
i += 1
print "Iteration #%i" % i
sleep(1)
finally:
print "Goodbye"
Now see the Ctrl+C behaviour:
$ ./signals-test.py default
Hello
Iteration #1
Iteration #2
Iteration #3
Iteration #4
^CGoodbye
Traceback (most recent call last):
File "./signals-test.py", line 21, in <module>
sleep(1)
KeyboardInterrupt
$ echo $?
1
This time I send it SIGTERM
after 4 iterations with kill $(ps aux | grep signals-test | awk '/python/ {print $2}')
:
$ ./signals-test.py default
Hello
Iteration #1
Iteration #2
Iteration #3
Iteration #4
Terminated
$ echo $?
143
This time I enable my custom SIGTERM
handler and send it SIGTERM
:
$ ./signals-test.py handle_signal
Hello
Iteration #1
Iteration #2
Iteration #3
Iteration #4
Goodbye
$ echo $?
0
In Swift you can use the following equalities to determine the kind of device on Universal apps:
UIDevice.current.userInterfaceIdiom == .phone
// or
UIDevice.current.userInterfaceIdiom == .pad
Usage would then be something like:
if UIDevice.current.userInterfaceIdiom == .pad {
// Available Idioms - .pad, .phone, .tv, .carPlay, .unspecified
// Implement your logic here
}
Add_ supplier is name of the form

compileOnly 'org.projectlombok:lombok'
testAnnotationProcessor 'org.projectlombok:lombok'
testCompileOnly 'org.projectlombok:lombok'

I experienced the same problem with FZ-client, while my notebook connected via WLAN and DSL/Router. In the Site Manager connection settings I was applied Host:ftp.domain-name, Encryption:Only use plain FTP (insecure) and User:username@domain-name. Then the FTP-client succesfully connected to my website server. More FTP connection information could be found in the CPanel of the webserver. Hope this helps.
In PyCharm the parameters are added in the Script Parameters
as you did but, they are enclosed in double quotes ""
and without specifying the Interpreter flags like -s
. Those flags are specified in the Interpreter options
box.
Script Parameters box contents:
"file1.txt" "file2.txt"
Interpeter flags:
-s
Or, visually:
Then, with a simple test file to evaluate:
if __name__ == "__main__":

We get the parameters we provided (with sys.argv[0]
holding the script name of course):

better to use touchstart
event with .on()
jQuery method:
$(window).load(function() { // better to use $(document).ready(function(){
$('.List li').on('click touchstart', function() {
$('.Div').slideDown('500');
});
});
And i don't understand why you are using $(window).load()
method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready()
method which does not wait for each element on the page to be loaded first.
This can be done using httpPostedFileBase class returns the HttpInputStreamObject as per specified here
You should convert the stream into byte array and then you can read file content
Please refer following link
http://msdn.microsoft.com/en-us/library/system.web.httprequest.inputstream.aspx]
Hope this helps
UPDATE :
The stream that you get from your HTTP call is read-only sequential (non-seekable) and the FileStream is read/write seekable. You will need first to read the entire stream from the HTTP call into a byte array, then create the FileStream from that array.
Taken from here
// Read bytes from http input stream
BinaryReader b = new BinaryReader(file.InputStream);
byte[] binData = b.ReadBytes(file.ContentLength);
string result = System.Text.Encoding.UTF8.GetString(binData);

The termination of an array of characters with a null character is just a convention that is specifically for strings in C. You are dealing with something completely different -- an array of character pointers -- so it really has no relation to the convention for C strings. Sure, you could choose to terminate it with a null pointer; that perhaps could be your convention for arrays of pointers. There are other ways to do it. You can't ask people how it "should" work, because you're assuming some convention that isn't there.
You need to use command:
git config --global core.editor "'C:\Program Files\Microsoft VS Code\code.exe' -n -w"
Make sure you can start your editor from Git Bash
If you want to use Code.exe with short path, you can do this by adding the following line to your .bash_profile:
alias vscode="C:/Program\ Files/Microsoft\ VS\ Code/Code.exe"
And now, you can call it using only vscode
command(or whatever you named it)
Some additional info:
Setup will add Visual Studio Code to your %PATH%, so from the console you can type 'code' to open VS Code on that folder. You will need to restart your console after the installation for the change to the %PATH% environmental variable to take effect.
Note that the Element::innerText
property will not contain the text which has been hidden by CSS style "display:none
" in Google Chrome (as well it will drop the content that has been masked by other CSS technics (including font-size:0, color:transparent, and a few other similar effects that cause the text not to be rendered in any visible way).
Other CSS properties are also considered :
<br \>
that generates an inline newline will also generate an newline in the value of innerText.But Element::textContent
will still contain ALL contents of inner text elements independantly of the applied CSS even if they are invisible. And no extra newlines or whitespaces will be generated in textContent, which just ignores all styles and the structure and inline/block or positioned types of inner elements.
A copy/paste operation using mouse selection will discard the hidden text in the plain-text format that is put in the clipboard, so it won't contain everything in the textContent
, but only what is within innerText
(after whitespace/newline generation as above).
Both properties are then supported in Google Chrome, but their content may then be different. Older browsers still included in innetText everything like what textContent now contains (but their behavior in relation with then generation of whitespaces/newlines was inconsistant).
jQuery will solve these inconsistencies between browsers using the ".text()" method added to the parsed elements it returns via a $() query. Internally, it solves the difficulties by looking into the HTML DOM, working only with the "node" level. So it will return something looking more like the standard textContent.
The caveat is that that this jQuery method will not insert any extra spaces or line breaks that may be visible on screen caused by subelements (like <br />
) of the content.
If you design some scripts for accessibility and your stylesheet is parsed for non-aural rendering, such as plugins used to communicate with a Braille reader, this tool should use the textContent if it must include the specific punctuation signs that are added in spans styled with "display:none" and that are typically included in pages (for example for superscripts/subscripts), otherwise the innerText will be very confusive on the Braille reader.
Texts hidden by CSS tricks are now typically ignored by major search engines (that will also parse the CSS of your HTML pages, and will also ignore texts that are not in contrasting colors on the background) using an HTML/CSS parser and the DOM property "innerText" exactly like in modern visual browsers (at least this invisible content will not be indexed so hidden text cannot be used as a trick to force the inclusion of some keywords in the page to check its content) ; but this hidden text will be stil displayed in the result page (if the page was still qualified from the index to be included in results), using the "textContent" property instead of the full HTML to strip the extra styles and scripts.
IF you assign some plain-text in any one of these two properties, this will overwrite the inner markup and styles applied to it (only the assigned element will keep its type, attributes and styles), so both properties will then contain the same content. However, some browsers will now no longer honor the write to innerText, and will only let you overwrite the textContent property (you cannot insert HTML markup when writing to these properties, as HTML special characters will be properly encoded using numeric character references to appear literally, if you then read the innerHTML
property after the assignment of innerText
or textContent
.
I just wanted to point out my answer since I know for
loop is faster then $.each
loop
here it is:
just add class="required"
to inputs you want to be required and then in jquery do:
$('#signup_form').submit(function(){
var fields = $('input.required');
for(var i=0;i<fields.length;i++){
if($(fields[i]).val() != ''){
//whatever
}
}
});
No need to hack settings. There is a simple way:
print(df.to_string())
Warning!
This answer is now outdated. DOM Level 4 introduced MutationObserver, providing an effective replacement for the deprecated mutation events. See this answer to another question for a better solution than the one presented here. Seriously. Don't poll the DOM every 100 milliseconds; it will waste CPU power and your users will hate you.
Since mutation events were deprecated in 2012, and you have no control over the inserted elements because they are added by someone else's code, your only option is to continuously check for them.
function checkDOMChange()
{
// check for any new element being inserted here,
// or a particular node being modified
// call the function again after 100 milliseconds
setTimeout( checkDOMChange, 100 );
}
Once this function is called, it will run every 100 milliseconds, which is 1/10 (one tenth) of a second. Unless you need real-time element observation, it should be enough.
If your application often uses http protocol then REST is best because of its light weight, and knowing that your application uses only http protocol choosing SOAP is not so good because it heavy,Better to make decision on web service selection based on the protocols we use in our applications.
You can still using the devil logic of setting options depending on your current Tmux version: see my previous answer.
But since Tmux v1.7, set-option
adds "-q" to silence errors and not print out anything (see changelog).
I recommend to use this feature, it's more readable and easily expandable.
Add this to your ~/.tmux.conf
:
# from v2.1
set -gq mouse on
# before v2.1
set -gq mode-mouse on
set -gq mouse-resize-pane on
set -gq mouse-select-pane on
set -gq mouse-select-window on
Restar tmux or source-file
your new .tmux.conf
Side note: I'm open to remove my old answer if people prefer this one
In your pattern, you simply want to match all text between the two tags. Thus, you could use for example a [\w\W]
to match all characters.
function getTextBetweenTags($string, $tagname) {
$pattern = "/<$tagname>([\w\W]*?)<\/$tagname>/";
preg_match($pattern, $string, $matches);
return $matches[1];
}
From Sort an array of associative arrays by value of given key in php:
by using usort (http://php.net/usort) , we can sort an array in ascending and descending order. just we need to create a function and pass it as parameter in usort. As per below example used greater than for ascending order if we passed less than condition then it's sort in descending order. Example :
$array = array(
array('price'=>'1000.50','product'=>'test1'),
array('price'=>'8800.50','product'=>'test2'),
array('price'=>'200.0','product'=>'test3')
);
function cmp($a, $b) {
return $a['price'] > $b['price'];
}
usort($array, "cmp");
print_r($array);
Output:
Array
(
[0] => Array
(
[price] => 200.0
[product] => test3
)
[1] => Array
(
[price] => 1000.50
[product] => test1
)
[2] => Array
(
[price] => 8800.50
[product] => test2
)
)
If you are using the Git Credential Manager on Windows...
git config -l
should show:
credential.helper=manager
However, if you are not getting prompted for a credential then follow these steps:
Also ensure you have not set HTTP_PROXY
, HTTPS_PROXY
, NO_PROXY
environmental variables if you have proxy and your Git server is on the internal network.
You can also test Git fetch/push/pull using git-gui
which links to credential manager binaries in C:\Users\<username>\AppData\Local\Programs\Git\mingw64\libexec\git-core
Basics
You may not know it but, in JavaScript, whenever we interact with string, number or boolean primitives we enter a hidden world of object shadows and coercion.
string, number, boolean, null, undefined, and symbol.
In JavaScript there are 7 primitive types: undefined
, null
, boolean
, string
, number
, bigint
and symbol
. Everything else is an object. The primitive types boolean
, string
and number
can be wrapped by their object counterparts. These objects are instances of the Boolean
, String
and Number
constructors respectively.
typeof true; //"boolean"
typeof new Boolean(true); //"object"
typeof "this is a string"; //"string"
typeof new String("this is a string"); //"object"
typeof 123; //"number"
typeof new Number(123); //"object"
If primitives have no properties, why does "this is a string".length
return a value?
Because JavaScript will readily coerce between primitives and objects. In this case the string value is coerced to a string object in order to access the property length. The string object is only used for a fraction of second after which it is sacrificed to the Gods of garbage collection – but in the spirit of the TV discovery shows, we will trap the elusive creature and preserve it for further analysis…
To demonstrate this further consider the following example in which we are adding a new property to String constructor prototype.
String.prototype.sampleProperty = 5;
var str = "this is a string";
str.sampleProperty; // 5
By this means primitives have access to all the properties (including methods) defined by their respective object constructors.
So we saw that primitive types will appropriately coerce to their respective Object counterpart when required.
Analysis of toString()
method
Consider the following code
var myObj = {lhs: 3, rhs: 2};
var myFunc = function(){}
var myString = "This is a sample String";
var myNumber = 4;
var myArray = [2, 3, 5];
myObj.toString(); // "[object Object]"
myFunc.toString(); // "function(){}"
myString.toString(); // "This is a sample String"
myNumber.toString(); // "4"
myArray.toString(); // "2,3,5"
As discussed above, what's really happening is when we call toString()
method on a primitive type, it has to be coerced into its object counterpart before it can invoke the method.
i.e. myNumber.toString()
is equivalent to Number.prototype.toString.call(myNumber)
and similarly for other primitive types.
But what if instead of primitive type being passed into toString()
method of its corresponding Object constructor function counterpart, we force the primitive type to be passed as parameter onto toString()
method of Object function constructor (Object.prototype.toString.call(x)
)?
Closer look at Object.prototype.toString()
As per the documentation, When the toString method is called, the following steps are taken:
- If the
this
value isundefined
, return"[object Undefined]"
.- If the
this
value isnull
, return"[object Null]"
.- If this value is none of the above, Let
O
be the result of callingtoObject
passing thethis
value as the argument.- Let class be the value of the
[[Class]]
internal property ofO
.- Return the String value that is the result of concatenating the three Strings
"[object "
,class
, and"]"
.
Understand this from the following example
var myObj = {lhs: 3, rhs: 2};
var myFunc = function(){}
var myString = "This is a sample String";
var myNumber = 4;
var myArray = [2, 3, 5];
var myUndefined = undefined;
var myNull = null;
Object.prototype.toString.call(myObj); // "[object Object]"
Object.prototype.toString.call(myFunc); // "[object Function]"
Object.prototype.toString.call(myString); // "[object String]"
Object.prototype.toString.call(myNumber); // "[object Number]"
Object.prototype.toString.call(myArray); // "[object Array]"
Object.prototype.toString.call(myUndefined); // "[object Undefined]"
Object.prototype.toString.call(myNull); // "[object Null]"

I had the same problem with a big project with many submodules. Based on the answers of Chris Johnsen here and VonC here I build a short bash script which iterates through all existing gitlink entries and adds them as proper submodules.
#!/bin/bash
# Read all submodules in current git
MODULES=`git ls-files --stage | grep 160000`
# Iterate through every submodule path
while read -r MOD; do
# extract submodule path (split line at whitespace and take string with index 3)
ARRIN=(${MOD})
MODPATH=${ARRIN[3]}
# grep module url from .git file in submodule path
MODURL=`grep "url = " $MODPATH/.git/config`
MODURL=${MODURL##*=}
# echo path and url for information
echo $MODPATH
echo $MODURL
# remove existing entry in submodule index
git rm --cached $MODPATH
# add new entry in submodule index
git submodule add $MODURL $MODPATH
done <<< "$MODULES"
This fixed it for me, I hope it is of any help.
I did the following to solve the mentioned problem. I got the mentioned problem when I was trying to run the built exe, even I successfully built the exe using pyinstaller. I did this on Windows 10.
All you have to do is add:
#include <string>
using namespace std;
at the top. (BTW I know this was posted in 2013 but I just wanted to answer)
"cat".toCharArray()
But if you need strings
"cat".split("")
Edit: which will return an empty first value.
This solved my problem, from preventign that an event gets fired by a children:
doSmth(){_x000D_
// what ever_x000D_
}
_x000D_
<div (click)="doSmth()">_x000D_
<div (click)="$event.stopPropagation()">_x000D_
<my-component></my-component>_x000D_
</div>_x000D_
</div>

I faced this issue, I was not able to copy zeppelin [1GB] directory into docker container and was getting issue
COPY failed: stat /var/lib/docker/tmp/docker-builder977188321/zeppelin-0.7.2-bin-all: no such file or directory
I am using docker Version: 17.09.0-ce and resolved the issue with the following steps.
Step 1: copy zeppelin directory [which i want to copy into docker package]into directory contain "Dockfile"
Step 2: edit Dockfile and add command [location where we want to copy] ADD ./zeppelin-0.7.2-bin-all /usr/local/
Step 3: go to directory which contain DockFile and run command [alternatives also available] docker build
Step 4: docker image created Successfully with logs
Step 5/9 : ADD ./zeppelin-0.7.2-bin-all /usr/local/ ---> 3691c902d9fe
Step 6/9 : WORKDIR $ZEPPELIN_HOME ---> 3adacfb024d8 .... Successfully built b67b9ea09f02
You can reset the staging area in a few ways:
Reset HEAD and add all necessary files to check-in again as below:
git reset HEAD ---> removes all files from the staging area
git add <files, that are required to be committed>
git commit -m "<commit message>"
git push
I'll add yet another solution to the problem using version 5.6 or later. Don't know if it's more efficient than the already great solutions (probably not), but to me it's just simpler to read:
$myArray = [
"key0" => 0,
"key1" => 1,
"key2" => 2
];
array_combine(
array_keys($myArray),
array_map(
function ($intVal) {
return strval($intVal);
},
$myArray
)
);
Using strval()
as an example function in the array_map
, this will generate:
array(3) {
["key0"]=>
string(1) "0"
["key1"]=>
string(1) "1"
["key2"]=>
string(1) "2"
}
Hopefully I'm not the only one who finds this pretty simple to grasp.
array_combine
creates a key => value
array from an array of keys and an array of values, the rest is pretty self explanatory.
invisible(cat("Dataset: ", dataset, fill = TRUE))
invisible(cat(" Width: " ,width, fill = TRUE))
invisible(cat(" Bin1: " ,bin1interval, fill = TRUE))
invisible(cat(" Bin2: " ,bin2interval, fill = TRUE))
invisible(cat(" Bin3: " ,bin3interval, fill = TRUE))
produces output without NULL at the end of the line or on the next line

Following many hours of search and testing i found following solution(by implementing different SO solutions) here it what didn't failed in any case i was getting crash.
Runnable runnable = new Runnable() {
@Override
public void run() {
//displayPopup,progress dialog or what ever action. example
ProgressDialogBox.setProgressBar(Constants.LOADING,youractivityName.this);
}};
Where logcat is indicating the crash is happening.. start a runnable .in my case at receiving broadcast.
runOnUiThread(new Runnable() {
@Override
public void run() {
if(!isFinishing()) {
new Handler().postAtTime(runnable,2000);
}
}
});
Is this what you are trying?

Use ModRewrite:
RewriteRule ^403.html$ - [F]
Just make sure you create a blank document called "403.html" in your www root or you'll get a 404 error instead of 403.
I can find following ways to do.
private static final String fileName = "C:/Input.txt";
public static void main(String[] args) throws IOException {
Stream<String> lines = Files.lines(Paths.get(fileName));
lines.toArray(String[]::new);
List<String> readAllLines = Files.readAllLines(Paths.get(fileName));
readAllLines.forEach(s -> System.out.println(s));
File file = new File(fileName);
Scanner scanner = new Scanner(file);
while (scanner.hasNext()) {
System.out.println(scanner.next());
}
If you are using homebrew and homebrew services, you can probably just do:
brew services stop postgresql
brew upgrade postgresql
brew postgresql-upgrade-database
brew services start postgresql
I think this might not work completely if you are using advanced postgres features, but it worked perfectly for me.
For MySQL Workbench 8.0 navigate to:
Server > Data Import
A new tab called Administration - Data Import/Restore appears. There you can choose to import a Dump Project Folder or use a specific SQL file according to your needs. Then you must select a schema where the data will be imported to, or you have to click the New... button to type a name for the new schema.
Then you can select the database objects to be imported or just click the Start Import button in the lower right part of the tab area.
Having done that and if the import was successful, you'll need to update the Schema Navigator by clicking the arrow circle icon.
That's it!
For more detailed info, check the MySQL Workbench Manual: 6.5.2 SQL Data Export and Import Wizard
There might be performance issues, std::endl

I stumbled upon this post recently and think that it needs an updated solution for the standard library's c++11 mutex (namely std::mutex).
I've pasted some code below (my first steps with a mutex - I learned concurrency on win32 with HANDLE, SetEvent, WaitForMultipleObjects etc).
Since it's my first attempt with std::mutex and friends, I'd love to see comments, suggestions and improvements!

You can use iText for do such things
//iText imports
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
for example:
try {
PdfReader reader = new PdfReader(INPUTFILE);
int n = reader.getNumberOfPages();
String str=PdfTextExtractor.getTextFromPage(reader, 2); //Extracting the content from a particular page.
System.out.println(str);
reader.close();
} catch (Exception e) {
System.out.println(e);
}
another one
try {
PdfReader reader = new PdfReader("c:/temp/test.pdf");
System.out.println("This PDF has "+reader.getNumberOfPages()+" pages.");
String page = PdfTextExtractor.getTextFromPage(reader, 2);
System.out.println("Page Content:\n\n"+page+"\n\n");
System.out.println("Is this document tampered: "+reader.isTampered());
System.out.println("Is this document encrypted: "+reader.isEncrypted());
} catch (IOException e) {
e.printStackTrace();
}
the above examples can only extract the text, but you need to do some more to remove hyperlinks, bullets, heading & numbers.

Sadly, many JSON C++ libraries have APIs that are non trivial to use, while JSON was intended to be easy to use.
So I tried jsoncpp from the gSOAP tools on the JSON doc shown in one of the answers above and this is the code generated with jsoncpp to construct a JSON object in C++ which is then written in JSON format to std::cout:
value x(ctx);
x["appDesc"]["description"] = "SomeDescription";
x["appDesc"]["message"] = "SomeMessage";
x["appName"]["description"] = "Home";
x["appName"]["message"] = "Welcome";
x["appName"]["imp"][0] = "awesome";
x["appName"]["imp"][1] = "best";
x["appName"]["imp"][2] = "good";
std::cout << x << std::endl;
and this is the code generated by jsoncpp to parse JSON from std::cin and extract its values (replace USE_VAL
as needed):
value x(ctx);
std::cin >> x;
if (x.soap->error)
exit(EXIT_FAILURE); // error parsing JSON
#define USE_VAL(path, val) std::cout << path << " = " << val << std::endl
if (x.has("appDesc"))
{
if (x["appDesc"].has("description"))
USE_VAL("$.appDesc.description", x["appDesc"]["description"]);
if (x["appDesc"].has("message"))
USE_VAL("$.appDesc.message", x["appDesc"]["message"]);
}
if (x.has("appName"))
{
if (x["appName"].has("description"))
USE_VAL("$.appName.description", x["appName"]["description"]);
if (x["appName"].has("message"))
USE_VAL("$.appName.message", x["appName"]["message"]);
if (x["appName"].has("imp"))
{
for (int i2 = 0; i2 < x["appName"]["imp"].size(); i2++)
USE_VAL("$.appName.imp[]", x["appName"]["imp"][i2]);
}
}
This code uses the JSON C++ API of gSOAP 2.8.28. I don't expect people to change libraries, but I think this comparison helps to put JSON C++ libraries in perspective.
Yes, it's intended to be checked in. I want to suggest that it gets its own unique commit. We find that it adds a lot of noise to our diffs.
Just ran into this. I'm getting over 6,000 records. Just decided I'd just do some paging. As in, I accept a page number in my MVC JsonResult endpoint, which is defaulted to 0 so it's not necessary, like so:
public JsonResult MyObjects(int pageNumber = 0)
Then instead of saying:
return Json(_repository.MyObjects.ToList(), JsonRequestBehavior.AllowGet);
I say:
return Json(_repository.MyObjects.OrderBy(obj => obj.ID).Skip(1000 * pageNumber).Take(1000).ToList(), JsonRequestBehavior.AllowGet);
It's very simple. Then, in JavaScript, instead of this:
function myAJAXCallback(items) {
// Do stuff here
}
I instead say:
var pageNumber = 0;
function myAJAXCallback(items) {
if(items.length == 1000)
// Call same endpoint but add this to the end: '?pageNumber=' + ++pageNumber
}
// Do stuff here
}
And append your records to whatever you were doing with them in the first place. Or just wait until all the calls finish and cobble the results together.

You are using DictWriter.writerows()
which expects a list of dicts, not a dict. You want DictWriter.writerow()
to write a single row.
You will also want to use DictWriter.writeheader()
if you want a header for you csv file.
You also might want to check out the with
statement for opening files. It's not only more pythonic and readable but handles closing for you, even when exceptions occur.
Example with these changes made:
import csv
my_dict = {"test": 1, "testing": 2}
with open('mycsvfile.csv', 'w') as f: # You will need 'wb' mode in Python 2.x
w = csv.DictWriter(f, my_dict.keys())
w.writeheader()
w.writerow(my_dict)
Which produces:
test,testing

Place it in a div and give it an id
<div id=myForm>
then create a really really simple css to go with it.

That's all you need.
I had a similar problem. I didn't quite need an ordered set but more a list with a fast indexOf

versions.

No. But you should really use console.log()
instead of alert()
for debugging.
In Chrome it even has the advantage of being able to print out entire objects (not just toString()
).
According to documentation you can use the reverse
argument.
filter:orderBy(array, expression[, reverse]);
Change your filter to:
orderBy: 'created_at':true
hope you are doing well.
you can use my code to crop image.you just have to make a class and use this class into your XMl
and java
classes.
Crop image.
you can crop your selected image into circle and square into many of option.
hope fully it will works for you.because this is totally manageable for you and you can change it according to you.
enjoy your work :)
I solved this by looking at this comment on JBIDE-11655 : deleting all .project, .settings and .classpath in my projects folder.

For those who are trying to install php-curl on PHP 7, it will result in an error. Actually if you are installing php-curl in PHP 7, the package name should be;

The database does not do joins -- or automatic "linking" between documents. However you can do it yourself client side. If you need to do 2, that is ok, but if you had to do 2000, the number of client/server turnarounds would make the operation slow.
In MongoDB a common pattern is embedding. In relational when normalizing things get broken into parts. Often in mongo these pieces end up being a single document, so no join is needed anyway. But when one is needed, one does it client-side.
Consider the classic ORDER, ORDER-LINEITEM example. One order and 8 line items are 9 rows in relational; in MongoDB we would typically just model this as a single BSON document which is an order with an array of embedded line items. So in that case, the join issue does not arise. However the order would have a CUSTOMER which probably is a separate collection - the client could read the cust_id from the order document, and then go fetch it as needed separately.
There are some videos and slides for schema design talks on the mongodb.org web site I belive.

If you're using PHP 5.3, you can use a DateTime
object and its add
method:
$Date1 = '2010-09-17';
$date = new DateTime($Date1);
$date->add(new DateInterval('P1D')); // P1D means a period of 1 day
$Date2 = $date->format('Y-m-d');
Take a look at the DateInterval
constructor manual page to see how to construct other periods to add to your date (2 days would be 'P2D'
, 3 would be 'P3D'
, and so on).
Without PHP 5.3, you should be able to use strtotime
the way you did it (I've tested it and it works in both 5.1.6 and 5.2.10):
$Date1 = '2010-09-17';
$Date2 = date('Y-m-d', strtotime($Date1 . " + 1 day"));
// var_dump($Date2) returns "2010-09-18"
To select a value from the dropdown use the index like this:
if we have the
<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true"></asp:DropDownList>
you would use :
DropDownList1.Items[DropDownList1.SelectedIndex].Value
this would return the value for the selected index.
Or purely HTML and CSS with no events:
<div style="z-index: 1; position: absolute;">
<a style="visibility: hidden;">Page link</a>
</div>
<a href="page.html">Page link</a>
You might want to use the timeit module instead.
If you are here for a filepath just use "\\"
import os
path = r"c:\file"+"\\"+"path"
os.path.normpath(path)
which will outputc:\file\path
I think nobody cares how a website was designed/implemented when it behaves great and it works fast.
I use both "table" and "div"/"span" tags in HTML markup.
Let me give you few arguments why I am choosing divs:
for a table you have to write at least 3 tags (table, tr, td, thead, tbody), for a nice design, sometimes you have a lot of nested tables
I like to have components on the page. I don't know how to explain exactly but will try. Suppose you need a logo and this have to be placed, just a small piece of it, over the next page content. Using tables you have to cut 2 images and put this into 2 different TDs. Using DIVs you can have a simple CSS to arange it as you want. Which solution do you like best?
when more then 3 nested tables for doing something I am thinking to redesign it using DIVs
BUT I am still using tables for:
tabular data
content that is expanding self
fast solutions (prototypes), because DIVs box model is different on each browser, because many generators are using tables, etc
You have two approaches. Selenium has been specifically written to NOT allow interaction with hidden elements. The rational is that if a person cannot perform that action, then neither should Selenium. Therefore, to perform the click via Selenium, you must perform the action a user would do to make that button visible (e.g mouse over event, click another element, etc) then perform the click once visible.
However, Selenium does allow you to execute Javascript within the context of an element, so you could write Javascript to perform the click event even if it is hidden.
My preference is to always try and perform the actions to make the button visible
Your best bet would be to anticipate prefixes, so:
"(|(displayName=SEARCHKEY*)(displayName=ITSM - SEARCHKEY*)(displayName=alt prefix - SEARCHKEY*))"
Clunky, but I'm doing a similar thing within my organization.
For an example data in your table such as combinations of
''
, null
and as well as actual value
than if you want to only actual value
and replace to ''
and null
value by #
symbol than execute this query
SELECT Column_Name = (CASE WHEN (Column_Name IS NULL OR Column_Name = '') THEN '#' ELSE Column_Name END) FROM Table_Name
and another way you can use it but this is little bit lengthy and instead of this you can also use IsNull
function but here only i am mentioning IIF
function
SELECT IIF(Column_Name IS NULL, '#', Column_Name) FROM Table_Name
SELECT IIF(Column_Name = '', '#', Column_Name) FROM Table_Name
-- and syntax of this query
SELECT IIF(Column_Name IS NULL, 'True Value', 'False Value') FROM Table_Name
Using os.path.split
or os.path.basename
as others suggest won't work in all cases: if you're running the script on Linux and attempt to process a classic windows-style path, it will fail.
Windows paths can use either backslash or forward slash as path separator. Therefore, the ntpath
module (which is equivalent to os.path when running on windows) will work for all(1) paths on all platforms.
import ntpath
ntpath.basename("a/b/c")
Of course, if the file ends with a slash, the basename will be empty, so make your own function to deal with it:
def path_leaf(path):
head, tail = ntpath.split(path)
return tail or ntpath.basename(head)
Verification:
>>> paths = ['a/b/c/', 'a/b/c', '\\a\\b\\c', '\\a\\b\\c\\', 'a\\b\\c',
... 'a/b/../../a/b/c/', 'a/b/../../a/b/c']
>>> [path_leaf(path) for path in paths]
['c', 'c', 'c', 'c', 'c', 'c', 'c']
(1) There's one caveat: Linux filenames may contain backslashes. So on linux, r'a/b\c'
always refers to the file b\c
in the a
folder, while on Windows, it always refers to the c
file in the b
subfolder of the a
folder. So when both forward and backward slashes are used in a path, you need to know the associated platform to be able to interpret it correctly. In practice it's usually safe to assume it's a windows path since backslashes are seldom used in Linux filenames, but keep this in mind when you code so you don't create accidental security holes.
You need to add use Response;
facade in header at your file.
Only then you can successfully retrieve your data with
return Response::json($data);
KyleMit's answer worked for me (thank you!), but I noticed that with select2 elements that allow for searching, trying to tab to the next element wouldn't work (tab order was effectively lost), so I added code to set focus back to the main select2 element when the dropdown is closing:
$(document).on('focus', '.select2', function (e) {
if (e.originalEvent) {
var s2element = $(this).siblings('select');
s2element.select2('open');
// Set focus back to select2 element on closing.
s2element.on('select2:closing', function (e) {
s2element.select2('focus');
});
}
});
have you tried:
.image_block{
text-align: center;
vertical-align: bottom;
}
Swift 4.2 / 5
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(willEnterForeground),

@objc func willEnterForeground() {
// do what's needed
}
There is a lib called jnotify that wraps inotify on linux and has also support for windows. Never used it and I don't know how good it is, but it's worth a try I'd say.
getSupportActionBar().setDisplayShowTitleEnabled(false);
please, be sure your connected to a ubuntu server, I Had the same problem but I was connected to other distro, check the AMI value in your details instance, it should be something like
AMI: ubuntu/images/ebs/ubuntu-precise-12.04-amd64-server-20130411.1
hope it helps
This is not exactly an answer, rather sharing my findings, and hopefully getting some critical argument for/against it, as specifically I am not aware how efficient it is.
I recently had a need to do this for my project. I did this using Object.assign
, more precisely it is done something like this:Object.assign(new Person(...), anObjectLikePerson)
.
Here is link to my JSFiddle, and also the main part of the code:
function Person(firstName, lastName) {
this.firstName = firstName;
this.lastName = lastName;
this.getFullName = function() {
return this.lastName + ' ' + this.firstName;
}
}
var persons = [{
lastName: "Freeman",
firstName: "Gordon"
}, {
lastName: "Smith",
firstName: "John"
}];
var stronglyTypedPersons = [];
for (var i = 0; i < persons.length; i++) {
stronglyTypedPersons.push(Object.assign(new Person("", ""), persons[i]));
}
There's, however, slight difference among all these options which
I found out that
If you do
string URL = Server.MapPath("~");
or
string URL = Server.MapPath("/");
or
string URL = HttpRuntime.AppDomainAppPath;
your URL will display resources in your link like this:
"file:///d:/InetPUB/HOME/Index/bin/Resources/HandlerDoc.htm"
But if you want your URL to show only virtual path not the resources location, you should do
string URL = HttpRuntime.AppDomainAppVirtualPath;
then, your URL is displaying a virtual path to your resources as below
"http://HOME/Index/bin/Resources/HandlerDoc.htm"
I use div instead of tables and am able to target classes within the main class, as below:
.main {
.width: 800px;
.margin: 0 auto;
.text-align: center;
}
.main .table {
width: 80%;
}
.main .row {
/ ***something ***/
}
.main .column {
font-size: 14px;
display: inline-block;
}
.main .left {
width: 140px;
margin-right: 5px;
font-size: 12px;
}
.main .right {
width: auto;
margin-right: 20px;
color: #fff;
font-size: 13px;
font-weight: normal;
}
<div class="main">
<div class="table">
<div class="row">
<div class="column left">Swing Over Bed</div>
<div class="column right">650mm</div>
<div class="column left">Swing In Gap</div>
<div class="column right">800mm</div>
</div>
</div>
</div>
If you want to style a particular "cell" exclusively you can use another sub-class or the id of the div e.g:
.main #red { color: red; }
<div class="main">
<div class="table">
<div class="row">
<div id="red" class="column left">Swing Over Bed</div>
<div class="column right">650mm</div>
<div class="column left">Swing In Gap</div>
<div class="column right">800mm</div>
</div>
</div>
</div>
Be aware of an issue with sparse unique indexes in MongoDB. I've hit it and it is extremely cumbersome to workaround.
The problem is this - you have a field, which is unique if present and you wish to find all the objects where the field is absent. The way sparse unique indexes are implemented in Mongo is that objects where that field is missing are not in the index at all - they cannot be retrieved by a query on that field - {$exists: false}
just does not work.
The only workaround I have come up with is having a special null family of values, where an empty value is translated to a special prefix (like null:) concatenated to a uuid. This is a real headache, because one has to take care of transforming to/from the empty values when writing/quering/reading. A major nuisance.
I have never used server side javascript execution in MongoDB (it is not advised anyway) and their map/reduce has awful performance when there is just one Mongo node. Because of all these reasons I am now considering to check out CouchDB, maybe it fits more to my particular scenario.
BTW, if anyone knows the link to the respective Mongo issue describing the sparse unique index problem - please share.
I fixed, Work for me.
var table = $('#example').DataTable();
$('#container').css( 'display', 'block' );
table.columns.adjust().draw();
Or
var table = $('#example').DataTable();
table.columns.adjust().draw();
Reference: https://datatables.net/reference/api/columns.adjust()
Most of the answers here are to do the obvious check, that the length of the column as defined in the database isn't smaller than the data you are trying to pass into it.
Several times I have been bitten by going to SQL Management Studio, doing a quick:
sp_help 'mytable'
and be confused for a few minutes until I realize the column in question is an nvarchar, which means the length reported by sp_help is really double the real length supported because it's a double byte (unicode) datatype.
i.e. if sp_help reports nvarchar Length 40, you can store 20 characters max.
Linq equivalents of Map and Reduce: If you’re lucky enough to have linq then you don’t need to write your own map and reduce functions. C# 3.5 and Linq already has it albeit under different names.
Map is Select
:
Enumerable.Range(1, 10).Select(x => x + 2);
Reduce is Aggregate
:
Enumerable.Range(1, 10).Aggregate(0, (acc, x) => acc + x);
Filter is Where
:
Enumerable.Range(1, 10).Where(x => x % 2 == 0);
For me, Visual Studio on Mac doesn't support Node.js (editing and debugging) whereas Visual Studio Code does this very well.
What is happening is that Angular-translate is watching the expression with an event-based system, and just as in any other case of binding or two-way binding, an event is fired when the data is retrieved, and the value changed, which obviously doesn't work for translation. Translation data, unlike other dynamic data on the page, must, of course, show up immediately to the user. It can't pop in after the page loads.
Even if you can successfully debug this issue, the bigger problem is that the development work involved is huge. A developer has to manually extract every string on the site, put it in a .json file, manually reference it by string code (ie 'pageTitle' in this case). Most commercial sites have thousands of strings for which this needs to happen. And that is just the beginning. You now need a system of keeping the translations in synch when the underlying text changes in some of them, a system for sending the translation files out to the various translators, of reintegrating them into the build, of redeploying the site so the translators can see their changes in context, and on and on.
Also, as this is a 'binding', event-based system, an event is being fired for every single string on the page, which not only is a slower way to transform the page but can slow down all the actions on the page, if you start adding large numbers of events to it.
Anyway, using a post-processing translation platform makes more sense to me. Using GlobalizeIt for example, a translator can just go to a page on the site and start editing the text directly on the page for their language, and that's it: https://www.globalizeit.com/HowItWorks. No programming needed (though it can be programmatically extensible), it integrates easily with Angular: https://www.globalizeit.com/Translate/Angular, the transformation of the page happens in one go, and it always displays the translated text with the initial render of the page.
Full disclosure: I'm a co-founder :)
Changed function for deep casting (using recursion)

if (gettype($destination->{$name}) == "object") {

} else {

In the properties of the console you can activate the "Quick Edit Mode" under "Edit Options", that way you can paste inside the console just right clicking. Or you can use 'Insert' as they say.
Reasons of ignoring these argument is permanent generation has been removed in HotSpot for JDK8 because of following drawbacks
The Permanent Generation (PermGen) space has completely been removed and is kind of replaced by a new space called Metaspace. The consequences of the PermGen removal is that obviously the PermSize and MaxPermSize JVM arguments are ignored and you will never get a java.lang.OutOfMemoryError: PermGen error.
Advantages of MetaSpace
Metaspace Tuning
The maximum metaspace size can be set using the -XX:MaxMetaspaceSize flag, and the default is unlimited, which means that only your system memory is the limit. The -XX:MetaspaceSize tuning flag defines the initial size of metaspace If you don’t specify this flag, the Metaspace will dynamically re-size depending of the application demand at runtime.
Change enables other optimizations and features in the future
There is improved GC performace also.
From: http://jquery-howto.blogspot.com/2009/09/get-url-parameters-values-with-jquery.html
This is what you need :)
The following code will return a JavaScript Object containing the URL parameters:
// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
For example, if you have the URL:
http://www.example.com/?me=myValue&name2=SomeOtherValue
This code will return:
{
"me" : "myValue",
"name2" : "SomeOtherValue"
}
and you can do:
var me = getUrlVars()["me"];
var name2 = getUrlVars()["name2"];
My problem manifested with opening Win10 appxmanifest file (no pun intended). Simply installing Windows 10 tools and SDK (go to New->Project->Select Windows->Install Tools) fixed it.
I also have a site that has numerous urls with urlencoded characters. I am finding that many web APIs (including Google webmaster tools and several Drupal modules) trip over urlencoded characters. Many APIs automatically decode urls at some point in their process and then use the result as a URL or HTML. When I find one of these problems, I usually double encode the results (which turns %2f into %252f) for that API. However, this will break other APIs which are not expecting double encoding, so this is not a universal solution.
Personally I am getting rid of as many special characters in my URLs as possible.
Also, I am using id numbers in my URLs which do not depend on urldecoding:
example.com/blog/my-amazing-blog%2fstory/yesterday
becomes:
example.com/blog/12354/my-amazing-blog%2fstory/yesterday
in this case, my code only uses 12354 to look for the article, and the rest of the URL gets ignored by my system (but is still used for SEO.) Also, this number should appear BEFORE the unused URL components. that way, the url will still work, even if the %2f gets decoded incorrectly.
Also, be sure to use canonical tags to ensure that url mistakes don't translate into duplicate content.
I also encountered this question, I solved it through adding two conditions one is:
resultCode != null
the other is:
resultCode != RESULT_CANCELED
I used:
sudo yum install mod24_ssl
and it worked in my Amazon Linux AMI.
VBScript doesn't have Try/Catch. (VBScript language reference. If it had Try, it would be listed in the Statements section.)
On Error Resume Next
is the only error handling in VBScript. Sorry. If you want try/catch, JScript is an option. It's supported everywhere that VBScript is and has the same capabilities.
First I find out the number of commits between my feature branch and current master branch by
git checkout master
git rev-list master.. --count
Then, I create another branch based out my-feature branch, keep my-feature
branch untouched.
Lastly, I run
git checkout my-feature
git checkout -b my-rebased-feature
git checkout master
git checkout my-rebased-feature
git rebase master
git rebase head^x -i
// fixup/pick/rewrite
git push origin my-rebased-feature -f // force, if my-rebased-feature was ever pushed, otherwise no need for -f flag
// make a PR with clean history, delete both my-feature and my-rebased-feature after merge
Hope it helps, thanks.
We can simply pass the output of python inbuilt print function to a file after opening the file with the append option by using just two lines of code:
with open('filename.txt', 'a') as file:
print('\nThis printed data will store in a file', file=file)
Hope this may resolve the issue...
Note: this code works with python3 however, python2 is not being supported currently.
I'm using something like this:
$.when(
$.each(yourArray, function (key, value) {
// Do Something in loop here
})
).then(function () {
// After loop ends.
});
Try npm cache clean --force
if it doesn't work then manually delete %appdata%\npm-cache folder.
and install npm install npm@latest -g
It worked for me.
You are trying to run bash
, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d
, but you can do this by adding -it
to the command line, which ensures that the container has a valid tty associated with it and that stdin
remains connected:
docker run -it -d -p 52022:22 basickarl/docker-git-test
You would more commonly run some sort of long-lived non-interactive process (like sshd
, or a web server, or a database server, or a process manager like systemd
or supervisor
) when starting detached containers.
If you are trying to run a service like sshd
, you cannot simply run service ssh start
. This will -- depending on the distribution you're running inside your container -- do one of two things:
It will try to contact a process manager like systemd
or upstart
to start the service. Because there is no service manager running, this will fail.
It will actually start sshd
, but it will be started in the background. This means that (a) the service sshd start
command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.
If you want to run just ssh in a container, consider an example like this.
If you want to run sshd
and other processes inside the container, you will need to investigate some sort of process supervisor.
Your code won't work because you haven't assigned anything to n
before you first use it. Try this:
def oracle():
n = None
while n != 'Correct':
# etc...
A more readable approach is to move the test until later and use a break
:
def oracle():
guess = 50
while True:
print 'Current number = {0}'.format(guess)
n = raw_input("lower, higher or stop?: ")
if n == 'stop':
break
# etc...
Also input
in Python 2.x reads a line of input and then evaluates it. You want to use raw_input
.
Note: In Python 3.x, raw_input
has been renamed to input
and the old input
method no longer exists.
You have your arguments to the remote add

0 values of basic types (1)(2)map to false
.
Other values map to true
.
This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.
It's a common error to assume that as function return values, false
indicates failure. But in particular from main
it's false
that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.
There's no need to cast to bool
for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x
, works nicely. One can read !!
as a “convert to bool
” operator, much as -->
can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)
1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false
; any other value is converted to true
. For direct-initialization (8.5), a prvalue of type std::nullptr_t
can be converted to a prvalue of type bool
; the resulting value is false
.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool
, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”
Thumbs up first before use codes please!!! Create an image that fully cover the whole tab bar item for each item. This is needed to use the image you created as a tab bar item button. Be sure to make the height/width ratio be the same of each tab bar item too. Then:
UITabBarController *tabBarController = (UITabBarController *)self;
UITabBar *tabBar = tabBarController.tabBar;
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];
UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];
int x,y;
x = tabBar.frame.size.width/4 + 4; //when doing division, it may be rounded so that you need to add 1 to each item;
y = tabBar.frame.size.height + 10; //the height return always shorter, this is compensated by added by 10; you can change the value if u like.
//because the whole tab bar item will be replaced by an image, u dont need title
tabBarItem1.title = @"";
tabBarItem2.title = @"";
tabBarItem3.title = @"";
tabBarItem4.title = @"";
[tabBarItem1 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"item1-select.png"] scaledToSize:CGSizeMake(x, y)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"item1-deselect.png"] scaledToSize:CGSizeMake(x, y)]];//do the same thing for the other 3 bar item

Most simplest way is to use a IF(). Yes Mysql allows you to do conditional logic. IF function takes 3 params CONDITION, TRUE OUTCOME, FALSE OUTCOME.
So Logic is
if report.type = 'p'
amount = amount
else
amount = -1*amount
SQL
SELECT
id, IF(report.type = 'P', abs(amount), -1*abs(amount)) as amount
FROM report
You may skip abs() if all no's are +ve only
I've get closer to VisualStudio-like behaviour by setting the "Autocomplete Trigger for Java" to
.(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
and setting delay to 0.
Now I'd like to realize how to make it autocomplete method name when I press ( as VS's Intellisense does.
I faced the same problem i just add the singletone instance to get resource as referred by Erick
MainFragmentActivity.defaultInstance().getResources().getString(R.string.app_name);
you can also use
getActivity().getResources().getString(R.string.app_name);
I hope this will help.
If you wish, you can also use the column names instead of column numbers.
For example, if you want to read data from DataGridView on the 4. row and the "Name" column. It provides me a better understanding for which variable I am dealing with.
dataGridView.Rows[4].Cells["Name"].Value.ToString();
Hope it helps.
To add to the bunch of answers personally I prefer the following:
const webpack = require('webpack');
const prod = process.argv.indexOf('-p') !== -1;
module.exports = {
...
plugins: [
new webpack.DefinePlugin({
process: {
env: {
NODE_ENV: prod? `"production"`: '"development"'
}
}
}),
...
]
};
Using this there is no funky env variable or cross-platform problems (with env vars). All you do is run the normal webpack
or webpack -p
for dev or production respectively.
Reference: Github issue
you should do it the other way round:
Load the mainform
first and in its onload
event show your loginform
with showdialog()
which will prevent mainform
from showing until you have a result from the loginform
EDIT:
As this is a login form and if you do not need any variables from your mainform
(which is bad design in practice), you should really implement it in your program.cs as Davide and Cody suggested.
The official naming conventions aren't that strict, they don't even 'forbid' camel case notation except for prefix (com
in your example).
But I personally would avoid upper case letters and hyphenations, even numbers. I'd choose com.stackoverflow.mypackage
like Bragboy suggested too.
(hyphenations '-' are not legal in package names)
EDIT
Interesting - the language specification has something to say about naming conventions too.
In Chapter 7.7 Unique Package Names we see examples with package names that consist of upper case letters (so CamelCase notation would be OK) and they suggest to replace hyphonation by an underscore ("mary-lou" -> "mary_lou") and prefix java keywords with an underscore ("com.example.enum" -> "com.example._enum")
Some more examples for upper case letters in package names can be found in chapter 6.8.1 Package Names.
Simple binary threshold method is sufficient.
#include <string>
#include "opencv/highgui.h"
#include "opencv2/imgproc/imgproc.hpp"
using namespace std;
using namespace cv;
int main()
{
Mat img = imread("./img.jpg",0);//loading gray scale image
threshold(img, img, 128, 255, CV_THRESH_BINARY);//threshold binary, you can change threshold 128 to your convenient threshold
imwrite("./black-white.jpg",img);
return 0;
}
You can use GaussianBlur
to get a smooth black and white image.
If they implement the IDisposable interface then you should dispose them. The garbage collector will take care of the rest.
EDIT: best is to use the using
command when working with disposable items:
using(var con = new SqlConnection("..")){ ...
What happened with me was the Type of class was not UIViewController for the script attached to my view controller. It was for a UITabController..... I had mistakenly quickly created the wrong type of class.... So make sure the class if the correct type.. Hope this helps someone. I was in a rush and made this mistake.
Ok, I am not sure what are you using(MySQL, SLQ Server, Oracle, MS Access..) But you can try the code below. It work in W3School example DB. Here try this:
SELECT city, max(length(city)) FROM Customers;
You should be able to uninstall it using sc.exe (I think it is included in the Windows Resource Kit) by running the following in an "administrator" command prompt:
sc.exe delete <service name>
where <service name>
is the name of the service itself as you see it in the service management console, not of the exe.
You can find sc.exe in the System folder and it needs Administrative privileges to run. More information in this Microsoft KB article.
Alternatively, you can directly call the DeleteService() api. That way is a little more complex, since you need to get a handle to the service control manager via OpenSCManager() and so on, but on the other hand it gives you more control over what is happening.
Before submitting the form, call tinyMCE.triggerSave();
JSON.parse() converts any JSON String passed into the function, to a JSON object.
For better understanding, press F12 to open the Inspect Element of your browser, and go to the console to write the following commands:
var response = '{"result":true,"count":1}'; // Sample JSON object (string form)
JSON.parse(response); // Converts passed string to a JSON object.
Now run the command:
console.log(JSON.parse(response));
You'll get output as Object {result: true, count: 1}.
In order to use that object, you can assign it to the variable, let's say obj
:
var obj = JSON.parse(response);
Now by using obj
and the dot(.) operator you can access properties of the JSON Object.
Try to run the command
console.log(obj.result);
HTML doesn't recognize the &

I looked over this post someone had made: http://www.webmasterworld.com/forum21/8851.htm
A very simple way is to add the image as a background to a DIV then load an empty transparent gif set to the same size as the DIV in the foreground. that keeps the less determined out. They cant get the background without viewing the code and copying the URL and right clicking just downloads the transparent gif.
I prefer TIMESTAMPDIFF because you can easily change the unit if need be.
In angular, They separate it into 2 kind of url.
URL pattern /heroes/:limit
. Example: /heroes/20
route.snapshot.paramMap.get
.route.paramMap
to get paramsURL pattern /heroes
. Example: /heroes?limit=20
route.snapshot.queryParamMap
Disable it in onCreate()
final KeyListener edtTxtMessageKeyListener = edtTxtMessage.getKeyListener();
edtTxtMessage.setCursorVisible(false);
edtTxtMessage.setKeyListener(null);
And finally enable it in onClick() of EditText
edtTxtMessage.setCursorVisible(true);
edtTxtMessage.setKeyListener(edtTxtMessageKeyListener);
But the problem is with we have to click twise to bring OnScreenKeyboard for very first time.
@Workaround
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
Try this also in onClick() :)
to see changes that are not merged, I did this:
git checkout experiment
git merge --no-commit master
git diff --cached
Note: This shows changes in master
that are not in experiment
.
Don't forget to:
git merge --abort
When you're done lookin.
You can simply use the reset
button type.
<input type="text" />
<input type="reset" />
Edit: Remember that, the reset
button, reset the form for the original values, so, if the field has some value set on the field <input type="text" value="Name" />
after press reset
the field will reset the value inserted by user and come back with the word "name" in this example.
Reference: http://api.jquery.com/reset-selector/
As part of the C++ standard there exists some pre-defined macros that you can use. Section 16.8 of the C++ standard defines amongst other things, the __LINE__
macro.
__LINE__
: The line number of the current source line (a decimal constant).
__FILE__
: The presumed name of the source file (a character string literal).
__DATE__
: The date of translation of the source file (a character string literal...)
__TIME__
: The time of translation of the source file (a character string literal...)
__STDC__
: Whether__STDC__
is predefined
__cplusplus
: The name__cplusplus
is defined to the value 199711L when compiling a C ++ translation unit
So your code would be:
if(!Logical)
printf("Not logical value at line number %d \n",__LINE__);
I too had the same problem in eclipse using web.xml file
it showed me this " no grammar constraints referenced in the document "
but it can be resolved by adding tag
after the xml tag i.e. <?xml version = "1.0" encoding = "UTF-8"?>
Are you targeting the android.R or the one in your own project?
Are you sure your own R.java file is generated? Mistakes in your xml views could cause the R.java not to be generated. Go through your view files and make sure all the xml is right!
select * FROM (
select EmployeeID, Salary
, dense_rank() over (order by Salary DESC) ranking
from Employee
)
WHERE ranking = 2;
dense_rank() is used for the salary has to be same.So it give the proper output instead of using rank().
Change your configuration to this (add a slash):
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
Or the solution outlined below (proposed by @absiddiqueLive) will work for any domain:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
If you need to support http and https and preserve the protocol choice try the following:
RewriteRule ^login\$ https://www.%{HTTP_HOST}/login [R=301,L]
Where you replace login
with checkout.php
or whatever URL you need to support HTTPS on.
I'd argue this is a bad idea though. For the reasoning please read this answer.
Excellent answers already cover the difference between __str__
and __repr__
, which for me boils down to the former being readable even by an end user, and the latter being as useful as possible to developers. Given that, I find that the default implementation of __repr__
often fails to achieve this goal because it omits information useful to developers.
For this reason, if I have a simple enough __str__
, I generally just try to get the best of both worlds with something like:
def __repr__(self):
return '{0} ({1})'.format(object.__repr__(self), str(self))
I think you are looking for something like this:
let signUpViewController = SignUpViewController()
present(signUpViewController, animated: true, completion: nil)
If you want full screen of the new page:
present(signUpViewController, animated: true, completion: nil)
Hope this helps :)
I just ran into another cause for this error that you can check for.
The base class defined a pure virtual function as:
virtual int foo(int x = 0);
And the subclass had
int foo(int x) override;
The problem was the typo that the "=0"
was supposed to be outside of the parenthesis:
virtual int foo(int x) = 0;
So, in case you're scrolling this far down, you probably didn't find the answer - this is something else to check for.
The suggested technique above in Dave's answer is certainly a good design practice, and yes ultimately the required permission must be set in the AndroidManifest.xml file to access the external storage.
However, the Mono-esque way to add most (if not all, not sure) "manifest options" is through the attributes of the class implementing the activity (or service).
The Visual Studio Mono plugin automatically generates the manifest, so its best not to manually tamper with it (I'm sure there are cases where there is no other option).
For example:
[Activity(Label="MonoDroid App", MainLauncher=true, Permission="android.permission.WRITE_EXTERNAL_STORAGE")]
public class MonoActivity : Activity
{
protected override void OnCreate(Bundle bindle)
{
base.OnCreate(bindle);
}
}
In my case was Promise with no reject neither resolve, because my Promise function threw an exception. This mistake cause UnhandledPromiseRejectionWarning message.
void requestFocus(View editText, Activity activity)
{
try {
editText.requestFocus();
InputMethodManager imm = (InputMethodManager) a.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
} catch (Exception e) {
e.printStackTrace();
}
}
add this line too do not forget
activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
like this:
final String str = "This is a long sentence";
final String[] arr = str.split(" ", 2);
System.out.println(Arrays.toString(arr));
arr[0]
is the first word, arr[1]
is the rest
You're looking for isNaN()
:
console.log(!isNaN(123));_x000D_
console.log(!isNaN(-1.23));_x000D_
console.log(!isNaN(5-2));_x000D_
console.log(!isNaN(0));_x000D_
console.log(!isNaN("0"));_x000D_
console.log(!isNaN("2"));_x000D_
console.log(!isNaN("Hello"));_x000D_
console.log(!isNaN("2005/12/12"));
_x000D_
See JavaScript isNaN() Function at MDN.
You have to do a shift and mask (AND) operation. Let b be any byte and p be the index (>= 0) of the bit from which you want to take n bits (>= 1).
First you have to shift right b by p times:
x = b >> p;
Second you have to mask the result with n ones:
mask = (1 << n) - 1;
y = x & mask;
You can put everything in a macro:
#define TAKE_N_BITS_FROM(b, p, n) ((b) >> (p)) & ((1 << (n)) - 1)
position: absolute
will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static
.
Have your four divs nested inside the target div, give the target div position: relative
, and use position: absolute
on the others.
Structure your HTML similar to this:
<div id="container">
<div class="top left"></div>
<div class="top right"></div>
<div class="bottom left"></div>
<div class="bottom right"></div>
</div>
And this CSS should work:
#container {
position: relative;
}
#container > * {
position: absolute;
}
.left {
left: 0;
}
.right {
right: 0;
}
.top {
top: 0;
}
.bottom {
bottom: 0;
}
...
Acording to http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html, the limit is L + 2 bytes, where L < 2^16
, or 64k.
You shouldn't need to concern yourself with limiting it, it's automatically broken down into chunks that get added as the string grows, so it won't always blindly use 64k.
If you don't support legacy browsers, I'd use flexbox
because it's well supported and will simply solve most of your layout problems.
#table-id td:nth-child(1) {
/* nth-child(1) is the first column, change to fit your needs */
display: flex;
justify-content: center;
}
This centers all content in the first <td>
of every row.
I solved it by editing .git / config, adding:
[branch "name_branch"]
remote = origin
merge = refs/heads/name_branch
Then I went to .git / refs / heads / name_branch
and place the id of the last commitenter code here

I'm usually using
var dictionary:[String:String] = [:]
dictionary.removeAll()
There is also an alternate solution for those who aren't afraid of using hex editors (e.g. XVI32) [thanks to Trevor for this]: in the unpacked 1 installer executable (jdk-8uXX-windows-i586.exe
in case of JDK) simply replace all occurrences of RegDeleteKeyExA
(the name of API found in "new" ADVAPI32.DLL
) with RegDeleteKeyA
(legacy API name), followed by two hex '00's (to preserve padding/segmentation boundaries). The installer will complain about unsupported Windows version, but will work nevertheless.
For reference, the raw hex strings will be:
52 65 67 44 65 6C 65 74 65 4B 65 79 45 78 41
replaced with
52 65 67 44 65 6C 65 74 65 4B 65 79 41 00 00
Note: this procedure applies to both offline (standalone) and online (downloader) package.
1: some newer installer versions are packed with UPX - you'd need to unpack them first, otherwise you simply won't be able to find the hex string required
textBox1.Focus()
textBox1.SelectionStart = textBox1.Text.Length;
textBox1.ScrollToCaret();
didn't work for me (Windows 8.1, whatever the reason).
And since I'm still on .NET 2.0, I can't use ScrollToEnd.

I was having this same issue this morning. When I checked my Device Manager, it showed COM4 properly, and when I checked in the Arduino IDE COM4 just wasn't an option. Only COM1 was listed.
I tried unplugging and plugging my Arduino in and out a couple more times and eventually COM4 showed up again in the IDE. I didn't have to change any settings.
Hopefully that helps somebody.

I hope my experience can help somebody: I want to migrate my app Spring (using cas client) to Spring Boot (1.5 not 2.4 yet). I stucked with many problem like :
no main manifest attribute, in target/cas-client-web.jar
I want to make one unique jar with all dependencies. After some days in searching on the Internet. I can do my job with theses lines :

</plugin>
with start-class is your main class
<properties>
<java.version>1.8</java.version>
<start-class>com.test.Application</start-class>
</properties>
And my Application is like :
package com.test;
import java.util.Arrays;
import com.test.TestProperties;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.ApplicationContext;

public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
return args -> {
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
};
}
}
I too got the similar problem and I did like below..
Rt click the project, navigate to Run As --> click 6 Maven Clean and your build will be success..
SELECT
GROUP_CONCAT(DISTINCT (category))
FROM (
SELECT
SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
FROM
numbers INNER JOIN tableName
ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
) s;
This will return distinct values like: test1,test2,test4,test3
may be you can write like this:
#graphic {
background-image: url(image.jpg);
background-position: 0 -50px;
width: 200px;
height: 100px;
}
The safest way is to rely on the browser TextNode to correctly escape content. Here's an example:
function stripHTML(dirtyString) {_x000D_
var container = document.createElement('div');_x000D_
var text = document.createTextNode(dirtyString);_x000D_
container.appendChild(text);_x000D_
return container.innerHTML; // innerHTML will be a xss safe string_x000D_
}_x000D_
_x000D_
document.write( stripHTML('<p>some <span>content</span></p>') );_x000D_
document.write( stripHTML('<script><p>some <span>content</span></p>') );
_x000D_
The thing to remember here is that the browser escape the special characters of TextNodes when we access the html strings (innerHTML
, outerHTML
). By comparison, accessing text values (innerText
, textContent
) will yield raw strings, meaning they're unsafe and could contains XSS.
If you use jQuery, then using .text()
is safe and backward compatible. See the other answers to this question.
The simplest way in pure JavaScript if you work with browsers <= Internet Explorer 8 is:
string.replace(/(<([^>]+)>)/ig,"");
But there's some issue with parsing HTML with regex so this won't provide very good security. Also, this only takes care of HTML characters, so it is not totally xss-safe.

One more way is to extend the application (as my application was to inherit and customize the parent). It invokes the parent and its commandlinerunner automatically.
@SpringBootApplication

public static void main(String[] args) {
SpringApplication.run(ChildApplication.class, args);

To do it the ASP.NET way:

You need a little statistical knowledge to see this. R squared between two vectors is just the square of their correlation. So you can define you function as:
rsq <- function (x, y) cor(x, y) ^ 2
Sandipan's answer will return you exactly the same result (see the following proof), but as it stands it appears more readable (due to the evident $r.squared
).
Basically we fit a linear regression of y
over x
, and compute the ratio of regression sum of squares to total sum of squares.
lemma 1: a regression y ~ x
is equivalent to y - mean(y) ~ x - mean(x)
lemma 2: beta = cov(x, y) / var(x)
lemma 3: R.square = cor(x, y) ^ 2
R squared between two arbitrary vectors x
and y
(of the same length) is just a goodness measure of their linear relationship. Think twice!! R squared between x + a
and y + b
are identical for any constant shift a
and b
. So it is a weak or even useless measure on "goodness of prediction". Use MSE or RMSE instead:
I agree with 42-'s comment:
The R squared is reported by summary functions associated with regression functions. But only when such an estimate is statistically justified.
R squared can be a (but not the best) measure of "goodness of fit". But there is no justification that it can measure the goodness of out-of-sample prediction. If you split your data into training and testing parts and fit a regression model on the training one, you can get a valid R squared value on training part, but you can't legitimately compute an R squared on the test part. Some people did this, but I don't agree with it.
Here is very extreme example:
preds <- 1:4/4
actual <- 1:4
The R squared between those two vectors is 1. Yes of course, one is just a linear rescaling of the other so they have a perfect linear relationship. But, do you really think that the preds
is a good prediction on actual
??
Thanks for your comments 1, 2 and your answer of details.
You probably misunderstood the procedure. Given two vectors x
and y
, we first fit a regression line y ~ x
then compute regression sum of squares and total sum of squares. It looks like you skip this regression step and go straight to the sum of square computation. That is false, since the partition of sum of squares does not hold and you can't compute R squared in a consistent way.
As you demonstrated, this is just one way for computing R squared:
preds <- c(1, 2, 3)
actual <- c(2, 2, 4)
rss <- sum((preds - actual) ^ 2) ## residual sum of squares
tss <- sum((actual - mean(actual)) ^ 2) ## total sum of squares
rsq <- 1 - rss/tss
#[1] 0.25
But there is another:
regss <- sum((preds - mean(preds)) ^ 2) ## regression sum of squares
regss / tss
#[1] 0.75
Also, your formula can give a negative value (the proper value should be 1 as mentioned above in the Warning section).
preds <- 1:4 / 4
actual <- 1:4
rss <- sum((preds - actual) ^ 2) ## residual sum of squares
tss <- sum((actual - mean(actual)) ^ 2) ## total sum of squares
rsq <- 1 - rss/tss
#[1] -2.375
I had never expected that this answer could eventually be so long when I posted my initial answer 2 years ago. However, given the high views of this thread, I feel obliged to add more statistical details and discussions. I don't want to mislead people that just because they can compute an R squared so easily, they can use R squared everywhere.
Don't know who looks at your file, but if you open it in wordpad instead of notepad, the linebreaks will show correct. In case you're using a special file extension, associate it with wordpad and you're done with it. Or use any other more advanced text editor.
Non of the solutions worked for me. I had to kill the following process and re ran react-native run-android and it worked.
node ./local-cli/cli.js start
One possible could be like this,
HTML
<div class="box-left-mini">
<div class="front">this div is infront</div>
<div class="behind">
this div is behind
</div>
</div>
CSS
.box-left-mini{
float:left;
background-image:url(website-content/hotcampaign.png);
width:292px;
height:141px;
}
.front{
background-color:lightgreen;
}
.behind{
background-color:grey;
position:absolute;
width:100%;
height:100%;
top:0;
z-index:-1;
}
But it really depends on the layout of your div elements i.e. if they are floating, or absolute positioned etc.
Try to set user.language
and user.country
properties in sqldeveloper.conf
file located in sqldeveloper\bin folder (%APPDATA%\sqldeveloper\<version>\product.conf
for more recent versions) .
Sample for set french language:
IncludeConfFile ../../ide/bin/ide.conf
SetJavaHome D:\jdk1.6.0_25
AddVMOption -Doracle.ide.util.AddinPolicyUtils.OVERRIDE_FLAG=true
AddVMOption -Dsun.java2d.ddoffscreen=false
AddVMOption -Dwindows.shell.font.languages=
AddVMOption -Duser.language=fr
AddVMOption -Duser.country=FR
AddVMOption -XX:MaxPermSize=128M
AddVMOption -Doracle.jdbc.mapDateToTimestamp=false
IncludeConfFile sqldeveloper-nondebug.conf
To switch off language try to remove its support by editing oracle.translated.locales
option in ide.boot
file (located in ide\bin folder).
For example, if I want to 'break' french language support this option will be:
oracle.translated.locales = de,es,it,ja,ko,pt_BR,zh_CN,zh_TW
The original value was:
oracle.translated.locales = de,fr,es,it,ja,ko,pt_BR,zh_CN,zh_TW
The configuration above (sqldeveloper.conf file) will be wrong after remove french support and the french language does not appear as GUI localization.
In my case, the problem was styling header as "Header 1" but that style was not exist in the Word that I get the error because it was not an Office in English Language.
