The Apache HttpClient 4.5 way:
org.apache.http.ssl.SSLContextBuilder sslContextBuilder = SSLContextBuilder.create();
sslContextBuilder.loadTrustMaterial(new org.apache.http.conn.ssl.TrustSelfSignedStrategy());
SSLContext sslContext = sslContextBuilder.build();
org.apache.http.conn.ssl.SSLConnectionSocketFactory sslSocketFactory =
new SSLConnectionSocketFactory(sslContext, new org.apache.http.conn.ssl.DefaultHostnameVerifier());
HttpClientBuilder httpClientBuilder = HttpClients.custom().setSSLSocketFactory(sslSocketFactory);
httpClient = httpClientBuilder.build();
NOTE: org.apache.http.conn.ssl.SSLContextBuilder
is deprecated and org.apache.http.ssl.SSLContextBuilder
is the new one (notice conn
missing from the latter's package name).

Assuming a Book
class with a name
field getter, you can use Arrays.sort
method by passing an additional Comparator
specified using Java 8 constructs - Comparator default method & method references.
Arrays.sort(bookArray, Comparator.comparing(Book::getName));
Also, it's possible to compare on multiple fields using thenComparing
methods.
Arrays.sort(bookArray, Comparator.comparing(Book::getName)
.thenComparing(Book::getAuthor))
.thenComparingInt(Book::getId));
Benjamin Peterson is correct about the use of inspect.isclass()
for this job.
But note that you can test if a Class
object is a specific Class
, and therefore implicitly a Class
, using the built-in function issubclass.
Depending on your use-case this can be more pythonic.
from typing import Type, Any
def isclass(cl: Type[Any]):
try:
return issubclass(cl, cl)
except TypeError:
return False
Can then be used like this:
>>> class X():
... pass
...
>>> isclass(X)
True
>>> isclass(X())
False
Your code should be something like
require_once('class.twitter.php');
$t = new twitter;
$t->username = 'user';
$t->password = 'password';
$data = $t->publicTimeline();
As a note for future users who would like to avoid using FolderBrowserDialog
, Microsoft once released an API called the WindowsAPICodePack that had a helpful dialog called CommonOpenFileDialog
, that could be set into a IsFolderPicker
mode. The API is available from Microsoft as a NuGet package.
This is all I needed to install and use the CommonOpenFileDialog
. (NuGet handled the dependencies)
Install-Package Microsoft.WindowsAPICodePack-Shell
For the include line:
using Microsoft.WindowsAPICodePack.Dialogs;
Usage:
CommonOpenFileDialog dialog = new CommonOpenFileDialog();
dialog.InitialDirectory = "C:\\Users";
dialog.IsFolderPicker = true;
if (dialog.ShowDialog() == CommonFileDialogResult.Ok)
{
MessageBox.Show("You selected: " + dialog.FileName);
}
I try to explain this problem step by step in following example.
0) Question
I try to ask you like this :
i want to open page like facebook profile www.facebook.com/kaila.piyush
it get id from url and parse it to profile.php file and return featch data from database and show user to his profile
normally when we develope any website its link look like www.website.com/profile.php?id=username example.com/weblog/index.php?y=2000&m=11&d=23&id=5678
now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink
http://example.com/profile/userid (get a profile by the ID)
http://example.com/profile/username (get a profile by the username)
http://example.com/myprofile (get the profile of the currently logged-in user)
1) .htaccess
Create a .htaccess file in the root folder or update the existing one :
Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
# Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php
What does that do ?
If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.
2) index.php
Now, we want to know what action to trigger, so we need to read the URL :
In index.php :
// index.php
// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);
for ($i= 0; $i < sizeof($scriptName); $i++)
{
if ($requestURI[$i] == $scriptName[$i])
{
unset($requestURI[$i]);
}
}
$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :
$command = array(
[0] => 'profile',
[1] => 19837,
[2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :
// index.php
require_once("profile.php"); // We need this file
switch($command[0])
{
case ‘profile’ :
// We run the profile function from the profile.php file.
profile($command([1]);
break;
case ‘myprofile’ :
// We run the myProfile function from the profile.php file.
myProfile();
break;
default:
// Wrong page ! You could also redirect to your custom 404 page.
echo "404 Error : wrong page.";
break;
}
2) profile.php
Now in the profile.php file, we should have something like this :
// profile.php
function profile($chars)
{
// We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)
if (is_int($chars)) {
$id = $chars;
// Do the SQL to get the $user from his ID
// ........
} else {
$username = mysqli_real_escape_string($char);
// Do the SQL to get the $user from his username
// ...........
}
// Render your view with the $user variable
// .........
}
function myProfile()
{
// Get the currently logged-in user ID from the session :
$id = ....
// Run the above function :
profile($id);
}
Here is a good choice for gradients for both platforms iOS and Android:
https://github.com/react-native-community/react-native-linear-gradient
There are others approaches like expo, however react-native-linear-gradient have worked better for me.
<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} style={styles.linearGradient}>
<Text style={styles.buttonText}>
Sign in with Facebook
</Text>
</LinearGradient>
// Later on in your styles..
var styles = StyleSheet.create({
linearGradient: {
flex: 1,
paddingLeft: 15,
paddingRight: 15,
borderRadius: 5
},
buttonText: {
fontSize: 18,
fontFamily: 'Gill Sans',
textAlign: 'center',
margin: 10,
color: '#ffffff',
backgroundColor: 'transparent',
},
});
In bootstrap 4 you can simply override default value of bootstrap variable $popover-max-width
in your styles.scss file like so:
$popover-max-width: 300px;
@import "node_modules/bootstrap/scss/functions";
@import "node_modules/bootstrap/scss/variables";
@import "node_modules/bootstrap/scss/mixins";
@import "node_modules/bootstrap/scss/popover";

You're looking for:
.is(':visible')
Although you should probably change your selector to use jQuery considering you're using it in other places anyway:
if($('#testElement').is(':visible')) {
// Code
}
It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible')
on the child will return false
(which makes sense).
:visible
has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible
):
Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!
Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.
Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle()
:
function toggleTestElement() {
$('#testElement').fadeToggle('fast');
}
I ship opensource under LGPLv2 and even after several email conversations with Oracle they were unclear whether I was allowed to ship their binary JDBC driver with my distribution. The issue related to whether my license was compatible with their OTN terms so they suggested I was not permitted to ship the driver. Presumably related to this part
(b) to distribute the programs with applications you have developed to your customers provided that each such licensee agrees to license terms consistent with the terms of this Agreement
So even if you manage to publish the driver legally in your exclusive/local maven repository there is still the restriction on what you are permitted to do with that artifact. Seems absurd that even if I ship their driver in binary form along with the full OTN license file I still can't use it and must force my users to manually download the Oracle driver and drop into my library path before they can use my software.
. . IMPORTANT: See answer from @Mark Ingram below and @pjv for at better solution. . .
You could try this:
public Bitmap loadBitmap(String url)
{
Bitmap bm = null;
InputStream is = null;
BufferedInputStream bis = null;
try
{
URLConnection conn = new URL(url).openConnection();
conn.connect();
is = conn.getInputStream();
bis = new BufferedInputStream(is, 8192);
bm = BitmapFactory.decodeStream(bis);
}
catch (Exception e)
{
e.printStackTrace();
}
finally {
if (bis != null)
{
try
{
bis.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
if (is != null)
{
try
{
is.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
return bm;
}
But remember, this method should only be called from within a thread (not GUI -thread). I a AsyncTask.
String all = "";
try {
BufferedReader br = new BufferedReader(new FileReader(filePath));
String strLine;
while ((strLine = br.readLine()) != null){
all = all + strLine;
}
} catch (IOException e) {
Log.e("notes_err", e.getLocalizedMessage());
}
Solution without using extra ArrayList or combination of add() and remove() methods. Both can have negative impact if you have to reverse a huge list.
public ArrayList<Object> reverse(ArrayList<Object> list) {
for (int i = 0; i < list.size() / 2; i++) {
Object temp = list.get(i);
list.set(i, list.get(list.size() - i - 1));
list.set(list.size() - i - 1, temp);
}
return list;
}
Have you tried str = str.replace(/\W|_/g,'');
it will return a string without any character and you can specify if any especial character after the pipe bar |
to catch them as well.
var str = "1324567890abc§$)% John Doe #$@'.replace(/\W|_/g, '');
it will return str = 1324567890abcJohnDoe
or look for digits and letters and replace them for empty string (""):
var str = "1324567890abc§$)% John Doe #$@".replace(/\w|_/g, '');
it will return str = '§$)% #$@';
You may want to use a nullable datetime. Datetime? someDate = null;
You may find instances of people using DateTime.Max
or DateTime.Min
in such instances, but I highly doubt you want to do that. It leads to bugs with edge cases, code that's harder to read, etc.
Make sure when you create a txt file you don't type in the name "name.txt", just type in "name". If you type "name.txt" Eclipse will see it as "name.txt.txt". This solved it for me. Also save the file in the src folder, not the folder were the .java resides, one folder up.
Jquery later allowed you to to find the parents with the .parents()
method.
Hence I recommend using:
var $div = $('#divid').parents('div[class^="div-a"]');
This gives all parent nodes matching the selector. To get the first parent matching the selector use:
var $div = $('#divid').parents('div[class^="div-a"]').eq(0);
For other such DOM traversal queries, check out the documentation on traversing the DOM.
I found the WINDOWS-1252
encoding to be the least frustrating when dealing with Excel. Since its basically Microsofts own proprietary character set, one can assume it will work on both the Mac and the Windows version of MS-Excel. Both versions at least include a corresponding "File origin" or "File encoding" selector which correctly reads the data.
Depending on your system and the tools you use, this encoding could also be named CP1252
, ANSI
, Windows (ANSI)
, MS-ANSI
or just Windows
, among other variations.
This encoding is a superset of ISO-8859-1
(aka LATIN1
and others), so you can fallback to ISO-8859-1
if you cannot use WINDOWS-1252
for some reason. Be advised that ISO-8859-1
is missing some characters from WINDOWS-1252

Conversion is done differently in every tool and language. However, suppose you have a file query_result.csv
which you know is UTF-8
encoded. Convert it to WINDOWS-1252
using iconv
:
iconv -f UTF-8 -t WINDOWS-1252 query_result.csv > query_result-win.csv
If you have parameters in quotes that containing spaces, %*
will not work correctly.
The best solution I found is to have a loop that joins all arguments: https://serverfault.com/a/22541
set args=%1
shift
:start
if [%1] == [] goto done
set args=%args% %1
shift
goto start
:done
(use %args% here)
Pay attention, if you use cv.CV_THRESH_BINARY
means every pixel greater than threshold becomes the maxValue (in your case 255), otherwise the value is 0. Obviously if your threshold is 0 everything becomes white (maxValue = 255) and if the value is 255 everything becomes black (i.e. 0).
If you don't want to work out a threshold, you can use the Otsu's method. But this algorithm only works with 8bit images in the implementation of OpenCV. If your image is 8bit use the algorithm like this:
cv.Threshold(im_gray_mat, im_bw_mat, threshold, 255, cv.CV_THRESH_BINARY | cv.CV_THRESH_OTSU);
No matter the value of threshold if you have a 8bit image.

In JSFiddle, when you set the wrapping to "onLoad" or "onDomready", the functions you define are only defined inside that block, and cannot be accessed by outside event handlers.
Easiest fix is to change:
function something(...)
To:
window.something = function(...)
import os,shutil
current_path = "" ## source path
new_path = "" ## destination path
os.chdir(current_path)

Try defaulting the exports in your components:
import React from 'react';
import Navbar from 'react-bootstrap/lib/Navbar';
export default class MyNavbar extends React.Component {
render(){
return (
<Navbar className="navbar-dark" fluid>
...
</Navbar>
);
}
}
by using default you express that's going to be member in that module which would be imported if no specific member name is provided. You could also express you want to import the specific member called MyNavbar by doing so: import {MyNavbar} from './comp/my-navbar.jsx'; in this case, no default is needed
Cause you need to add jQuery library to your file:
jQuery UI is just an addon to jQuery which means that
first you need to include the jQuery library → and then the UI.
<script src="path/to/your/jquery.min.js"></script>
<script src="path/to/your/jquery.ui.min.js"></script>
The iBeacon output power is measured (calibrated) at a distance of 1 meter. Let's suppose that this is -59 dBm (just an example). The iBeacon will include this number as part of its LE advertisment.
The listening device (iPhone, etc), will measure the RSSI of the device. Let's suppose, for example, that this is, say, -72 dBm.
Since these numbers are in dBm, the ratio of the power is actually the difference in dB. So:
ratio_dB = txCalibratedPower - RSSI
To convert that into a linear ratio, we use the standard formula for dB:
ratio_linear = 10 ^ (ratio_dB / 10)
If we assume conservation of energy, then the signal strength must fall off as 1/r^2. So:
power = power_at_1_meter / r^2
. Solving for r, we get:
r = sqrt(ratio_linear)
In Javascript, the code would look like this:
function getRange(txCalibratedPower, rssi) {
var ratio_db = txCalibratedPower - rssi;
var ratio_linear = Math.pow(10, ratio_db / 10);
var r = Math.sqrt(ratio_linear);
return r;
}
Note, that, if you're inside a steel building, then perhaps there will be internal reflections that make the signal decay slower than 1/r^2. If the signal passes through a human body (water) then the signal will be attenuated. It's very likely that the antenna doesn't have equal gain in all directions. Metal objects in the room may create strange interference patterns. Etc, etc... YMMV.
If you are using Java with Hibernate then using NUMBER(1,0) is the best approach. As you can see in here, this value is automatically translated to Boolean by Hibernate.
If you don't want spaces/newlines, string addition seems to work:
var myString = String.Format(
"hello " +
"world" +
" i am {0}" +
" and I like {1}.",
animalType,
animalPreferenceType
);
// hello world i am a pony and I like other ponies.
You can run the above here if you like.
I agree with what seems to be the consensus here (return null if "not found" is a normal possible outcome, or throw an exception if the semantics of the situation require that the object always be found).
There is, however, a third possibility that might make sense depending on your particular situation. Your method could return a default object of some sort in the "not found" condition, allowing calling code to be assured that it will always receive a valid object without the need for null checking or exception catching.
I would not advice you to use built in font-awesome styling like the fa-5x etc; for fear they may change it and you would have to keep chainging your application code to meet up with the latest standard. You simply avoid this by giving each font-awesome class you want to style uniformly the same class say:
<i class="fa fa-facebook-square fa-sabi-social-icons" aria-hidden="true"></i>
<i class="fa fa-twitter-square fa-sabi-social-icons" aria-hidden="true"></i>
<i class="fa fa-google-plus-square fa-sabi-social-icons" aria-hidden="true"></i>
Here the class is fa-sabi-social-icons
Then in your css you can the style the fonts using the same css rules you would style a normal font with. e.g
.fa-sabi-social-icons {
color: //your color;
font-size: // your font-size in px, em or %;
text-shadow: 2px 2px #FF0000;
}
That should get your font-awesome fonts styled
As a one liner:
ImageIO.write(Scalr.resize(ImageIO.read(...), 150));
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.
Shellwrap is great tool for using the command-line in PHP!
Your example can be done quite easy and readable:
use MrRio\ShellWrap as sh;
$xml = (string)sh::curl(['u' => 'user:pass'], 'http://example.com/file.xml');
Try curl -v http://localhost:8080/
instead of 127.0.0.1

Your code sample didn't expand on part of your topic, namely symbols, and so that part of the question went unanswered.
If you have two strings, foo and bar, and both can be either a string or a symbol, you can test equality with
foo.to_s == bar.to_s
It's a little more efficient to skip the string conversions on operands with known type. So if foo is always a string
foo == bar.to_s
But the efficiency gain is almost certainly not worth demanding any extra work on behalf of the caller.
Prior to Ruby 2.2, avoid interning uncontrolled input strings for the purpose of comparison (with strings or symbols), because symbols are not garbage collected, and so you can open yourself to denial of service through resource exhaustion. Limit your use of symbols to values you control, i.e. literals in your code, and trusted configuration properties.
Ruby 2.2 introduced garbage collection of symbols.
JToken
is the base class for JObject
, JArray
, JProperty
, JValue
, etc. You can use the Children<T>()
method to get a filtered list of a JToken's children that are of a certain type, for example JObject
. Each JObject
has a collection of JProperty
objects, which can be accessed via the Properties()
method. For each JProperty
, you can get its Name
. (Of course you can also get the Value
if desired, which is another JToken
.)
Putting it all together we have:
JArray array = JArray.Parse(json);
foreach (JObject content in array.Children<JObject>())
{
foreach (JProperty prop in content.Properties())
{
Console.WriteLine(prop.Name);
}
}
Output:
MobileSiteContent
PageContent
Providing the implementation details for the steps proposed by @CodesInChaos:
1) Check if there is a Byte Order Mark
2) Check if the file is valid UTF8
3) Use the local "ANSI" codepage (ANSI as Microsoft defines it)
Step 2 works because most non ASCII sequences in codepages other that UTF8 are not valid UTF8. https://stackoverflow.com/a/4522251/867248 explains the tactic in more details.
using System; using System.IO; using System.Text;
// Using encoding from BOM or UTF8 if no BOM found,
// check if the file is valid, by reading all lines
// If decoding fails, use the local "ANSI" codepage
public string DetectFileEncoding(Stream fileStream)
{
var Utf8EncodingVerifier = Encoding.GetEncoding("utf-8", new EncoderExceptionFallback(), new DecoderExceptionFallback());
using (var reader = new StreamReader(fileStream, Utf8EncodingVerifier,
detectEncodingFromByteOrderMarks: true, leaveOpen: true, bufferSize: 1024))
{
string detectedEncoding;
try
{
while (!reader.EndOfStream)
{
var line = reader.ReadLine();
}
detectedEncoding = reader.CurrentEncoding.BodyName;
}
catch (Exception e)
{
// Failed to decode the file using the BOM/UT8.
// Assume it's local ANSI
detectedEncoding = "ISO-8859-1";
}
// Rewind the stream
fileStream.Seek(0, SeekOrigin.Begin);
return detectedEncoding;
}
}
[Test]
public void Test1()
{
Stream fs = File.OpenRead(@".\TestData\TextFile_ansi.csv");
var detectedEncoding = DetectFileEncoding(fs);
using (var reader = new StreamReader(fs, Encoding.GetEncoding(detectedEncoding)))
{
// Consume your file
var line = reader.ReadLine();
...
int c;
String raw = "";
do {
c = inputstream.read();
raw+=(char)c;

You can try the following VBA code to export Macro contents directly without converting them to VBA first. Unlike Tables, Forms, Reports, and Modules, the Macros are in a container called Scripts. But they are there and can be exported and imported using SaveAsText and LoadFromText
Option Compare Database
Option Explicit
Public Sub ExportDatabaseObjects()

Dim d As Document
Dim c As Container

Set c = db.Containers("Scripts")
For Each d In c.Documents
Application.SaveAsText acMacro, d.Name, sExportLocation & "Macro_" & d.Name & ".txt"

An alternative object to use is as follows:

Filling a DataSet with multiple tables can be done by sending multiple requests to the database, or in a faster way: Multiple SELECT statements can be sent to the database server in a single request. The problem here is that the tables generated from the queries have automatic names Table and Table1. However, the generated table names can be mapped to names that should be used in the DataSet.

Have in mind that clone()
doesn't work out of the box. You will have to implement Cloneable
and override the clone()
method making in public
.
There are a few alternatives, which are preferable (since the clone()
method has lots of design issues, as stated in other answers), and the copy-constructor would require manual work:
BeanUtils.cloneBean(original)
creates a shallow clone, like the one created by Object.clone()
. (this class is from commons-beanutils)
SerializationUtils.clone(original)
creates a deep clone. (i.e. the whole properties graph is cloned, not only the first level) (from commons-lang), but all classes must implement Serializable
Java Deep Cloning Library offers deep cloning without the need to implement Serializable
Use typings to access node functions from TypeScript:

If you don't have typings install it:

Many long (and correct) answers here. But usually you won't do these things manually - at least not when you set up your first projects for development (this is where you usually stumble upon these things). If you use koa for the backend: use koa-cors. Install via npm...
npm install --save koa-cors
...and use it in the code:
const cors = require('koa-cors');
const Koa = require('koa');
const app = new Koa();
app.use(cors());
problem solved.
For an alternative cryptography library, have a look at Bouncy Castle. It has AES and a lot of added functionality. It's a liberal open source library. You will have to use the lightweight, proprietary Bouncy Castle API for this to work though.
The ssh-copy-id is not able to locate the id_rsa.pub file that is generated by ssh-keygen in your system, Use the following command to complete:
locate *.pub

You can just use:
> names(LIST)
[1] "A" "B"
Obviously the names of the first element is just

I changed Private Function

you can try this
$('body').on('hidden.bs.modal', '.modal', function () {

I had this same problem on RHEL6. It turns out that the mysql.ini file in /etc/php.d only had a module name but needed a full path name. On my RHEL6 system the entry that works is:
; Enable mysql extension module
extension=/usr/lib64/php/modules/mysql.so
After modifying the file, I restarted apache and everything worked.
If you actually have a database, this is the most-simple way:
var lsPetOwners = ( from person in context.People
from pets in context.Pets
.Where(mypet => mypet.Owner == person.ID)
.DefaultIfEmpty()
select new { OwnerName = person.Name, Pet = pets.Name }
).ToList();
Tickcount is good, however i suggest running it 100 or 1000 times, and calculating an average. Not only makes it more measurable - in case of really fast/short functions, but helps dealing with some one-off effects caused by the overhead.
What is usage of "Constructor Chain"?
You use it for calling one constructor from another constructor.
How can implement "Constructor Chain"?
Use ": this (yourProperties)" keyword after definition of constructor. for example:
Class MyBillClass
{
private DateTime requestDate;
private int requestCount;
public MyBillClass()
{
/// ===== we naming "a" constructor ===== ///
requestDate = DateTime.Now;
}
public MyBillClass(int inputCount) : this()
{
/// ===== we naming "b" constructor ===== ///
/// ===== This method is "Chained Method" ===== ///
this.requestCount= inputCount;
}
}
Why is it useful?
Important reason is reduce coding, and prevention of duplicate code. such as repeated code for initializing property
Suppose some property in class must be initialized with specific value (In our sample, requestDate). And class have 2 or more constructor. Without "Constructor Chain", you must repeat initializaion code in all constractors of class.
How it work? (Or, What is execution sequence in "Constructor Chain")?
in above example, method "a" will be executed first, and then instruction sequence will return to method "b".
In other word, above code is equal with below:
Class MyBillClass
{
private DateTime requestDate;
private int requestCount;
public MyBillClass()
{
/// ===== we naming "a" constructor ===== ///
requestDate = DateTime.Now;
}
public MyBillClass(int inputCount) : this()
{
/// ===== we naming "b" constructor ===== ///
// ===== This method is "Chained Method" ===== ///
/// *** --- > Compiler execute "MyBillClass()" first, And then continue instruction sequence from here
this.requestCount= inputCount;
}
}
As usual, it depends on the application. There are cases where C# is probably negligibly slower, and other cases where C++ is 5 or 10 times faster, especially in cases where operations can be easily SIMD'd.
As mentioned by @Khaneddy2013, the cmd SQLCMD -L returns no server name when I run. Bcz I only have installed the SSMS (local db and server were not installed). After tried installing SqlLocaLDB and SQLEXPR32_x86_ENU(32 bit OS) I was able to connect. And now the cmd window shows the server names too.
In case you want the column name from the column location (the other way around to the OP question), you can use:
>>> df.columns.get_values()[location]
Using @DSM Example:
>>> df = DataFrame({"pear": [1,2,3], "apple": [2,3,4], "orange": [3,4,5]})
>>> df.columns
Index(['apple', 'orange', 'pear'], dtype='object')
>>> df.columns.get_values()[1]
'orange'
Other ways:
df.iloc[:,1].name
df.columns[location] #(thanks to @roobie-nuby for pointing that out in comments.)
It solves to me, for my purposes:
.select-container {
position:relative;
width:200px;
height:18px;
overflow:hidden;
border:1px solid white !important
}
.select-container select {
position:relative;
left:-2px;
top:-2px
}
To put more style will be necessary to use nested divs .
X:Name can cause memory issues if you have custom controls. It will keep a memory location for the NameScope entry.
I say never use x:Name unless you have to.
If I could, I would vote for the answer by Paulo. I tested it and understood the concept. I can confirm it works.
The find
command can output many parameters.
For example, add the following to the --printf
clause:
%a for attributes in the octal format
%n for the file name including a complete path
Example:
find Desktop/ -exec stat \{} --printf="%y %n\n" \; | sort -n -r | head -1
2011-02-14 22:57:39.000000000 +0100 Desktop/new file
Let me raise this question as well: Does the author of this question want to solve his problem using Bash or PHP? That should be specified.
CreateImage(size, depth, channels)
https://opencv.willowgarage.com/documentation/python/core_operations_on_arrays.html#CreateImage
The del statement is what you're looking for. If you have a dictionary named foo with a key called 'bar', you can delete 'bar' from foo like this:
del foo['bar']
Note that this permanently modifies the dictionary being operated on. If you want to keep the original dictionary, you'll have to create a copy beforehand:
>>> foo = {'bar': 'baz'}
>>> fu = dict(foo)
>>> del foo['bar']
>>> print foo
{}
>>> print fu
{'bar': 'baz'}
The dict
call makes a shallow copy. If you want a deep copy, use copy.deepcopy
.
Here's a method you can copy & paste, for your convenience:
def minus_key(key, dictionary):
shallow_copy = dict(dictionary)
del shallow_copy[key]
return shallow_copy
No matter how much you try to avoid, when you work with other developers, some of them will still prefer scriptlet and then insert the evil code into the project. Therefore, setting up the project at the first sign is very important if you really want to reduce the scriptlet code. There are several techniques to get over this (including several frameworks that other mentioned). However, if you prefer the pure JSP way, then use the JSTL tag file. The nice thing about this is you can also set up master pages for your project, so the other pages can inherit the master pages
Create a master page called base.tag under your WEB-INF/tags with the following content
<%@tag description="Overall Page template" pageEncoding="UTF-8"%> <%@attribute name="title" fragment="true" %> <html> <head> <title> <jsp:invoke fragment="title"></jsp:invoke> </title> </head> <body> <div id="page-header"> .... </div> <div id="page-body"> <jsp:doBody/> </div> <div id="page-footer"> ..... </div> </body> </html>
On this mater page, I created a fragment called "title", so that in the child page, I could insert more codes into this place of the master page. Also, the tag <jsp:doBody/>
will be replaced by the content of the child page
Create child page (child.jsp) in your WebContent folder:
<%@ taglib prefix="t" tagdir="/WEB-INF/tags" %> <t:base> <jsp:attribute name="title"> <bean:message key="hello.world" /> </jsp:attribute> <jsp:body> [Put your content of the child here] </jsp:body> </t:base>
<t:base>
is used to specify the master page you want to use (which is base.tag at this moment). All the content inside the tag <jsp:body>
here will replace the <jsp:doBody/>
on your master page. Your child page can also include any tag lib and you can use it normally like the other mentioned. However, if you use any scriptlet code here (<%= request.getParameter("name") %>
...) and try to run this page, you will get a JasperException because Scripting elements ( <%!, <jsp:declaration, <%=, <jsp:expression, <%, <jsp:scriptlet ) are disallowed here
. Therefore, there is no way other people can include the evil code into the jsp file
Calling this page from your controller:
You can easily call the child.jsp file from your controller. This also works nice with the struts framework
Example of calculating time:
work-start work-stop lunchbreak effective time
07:30:00 17:00:00 1.5 8 [=((A2-A1)*24)-A3]
If you subtract one time value from another the result you get will represent the fraction of 24 hours, so if you multiply the result with 24 you get the value represented in hours.
In other words: the operation is mutiply, but the meaning is to change the format of the number (from days to hours).
If you want to avoid writing all of this everytime, you can define a function :
def run(filename):
exec(open(filename).read())
and then call it
run('filename.py')
There is no way to delete or read the past history.
You could try going around it by emulating history in your own memory and calling history.pushState
everytime window popstate
event is emitted (which is proposed by the currently accepted Mike's answer), but it has a lot of disadvantages that will result in even worse UX than not supporting the browser history at all in your dynamic web app, because:
So even if you try going around it by building virtual history, it's very likely that it can also lead into a situation where you have blank history states (to which going back/forward does nothing), or where that going back/forward skips some of your history states totally.
You can use guide=FALSE
in scale_..._...()
to suppress legend.
For your example you should use scale_colour_continuous()
because length
is continuous variable (not discrete).
(p3 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
scale_colour_continuous(guide = FALSE) +
geom_point()
)
Or using function guides()
you should set FALSE
for that element/aesthetic that you don't want to appear as legend, for example, fill
, shape
, colour
.
p0 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
geom_point()
p0+guides(colour=FALSE)
Both provided solutions work in new ggplot2
version 2.0.0 but movies
dataset is no longer present in this library. Instead you have to use new package ggplot2movies
to check those solutions.
library(ggplot2movies)
data(movies)
mov <- subset(movies, length != "")
Docker CE is not supported on RHEL. Any way you are trying to get around that is not a supported way. You can see the supported platforms in the Docker Documentation. I suggest you either use a supported OS, or switch to Enterprise Edition.
You need a dict
:
my_dict = {'cheese': 'cake'}
Example code (from the docs):
>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True
You can read more about dictionaries here.
It's just shorthand for "constructor" - and it's what the constructor is called in IL, too. For example, open up Reflector and look at a type and you'll see members called .ctor
for the various constructors.
Try:
alias lock='gnome-screensaver; gnome-screensaver-command --lock'
or
lock() {
gnome-screensaver
gnome-screensaver-command --lock
}
in your .bashrc
The second solution allows you to use arguments.
<@include>
- The directive tag instructs the JSP compiler to merge contents of the included file into the JSP before creating the generated servlet code. It is the equivalent to cutting and pasting the text from your include page right into your JSP.
<jsp:include>
- The JSP Action tag on the other hand instructs the container to pause the execution of this page, go run the included page, and merge the output from that page into the output from this page.
Depending on your needs, you may either use
<@include>
or<jsp:include>
Whatever method you choose is not freeing you from performing the same validation on at the back end.
Numeric primitives in class scope are initialized to zero when not explicitly initialized.
Numeric primitives in local scope (variables in methods) must be explicitly initialized.
If you are only worried about division by zero exceptions, checking that your double is not exactly zero works great.
if(value != 0)
//divide by value is safe when value is not exactly zero.
Otherwise when checking if a floating point value like double
or float
is 0, an error threshold is used to detect if the value is near 0, but not quite 0.
public boolean isZero(double value, double threshold){
return value >= -threshold && value <= threshold;
}
app-routing.module.ts
const routes: Routes = [
{ path: 'products', component: ProductsComponent },
{ path: 'product/:id', component: ProductDetailsComponent },
{ path: '', redirectTo: '/products', pathMatch: 'full' },
];
In controller you can navigate like this,
this.router.navigate(['/products', productId]);
It will land you to path like this: http://localhost:4200/products/product-id
You can also use git diff HEAD file
to show the diff for a specific file.
See the EXAMPLE
section under git-diff(1)
You can come pretty damn close (but no cigar) to generating assembly that will reassemble, if that's what you are intending to do, using this rather crude and tediously long pipeline trick (replace /bin/bash with the file you intend to disassemble and bash.S with what you intend to send the output to):
objdump --no-show-raw-insn -Matt,att-mnemonic -Dz /bin/bash | grep -v "file format" | grep -v "(bad)" | sed '1,4d' | cut -d' ' -f2- | cut -d '<' -f2 | tr -d '>' | cut -f2- | sed -e "s/of\ section/#Disassembly\ of\ section/" | grep -v "\.\.\." > bash.S
Note how long this is, however. I really wish there was a better way (or, for that matter, a disassembler capable of outputting code that an assembler will recognize), but unfortunately there isn't.
It is very simple.

Although that file name changes, you'll want to find the latest ... that turns out just to be a big (very big) text file.
The answers here work for just 2 cells, but as soon as those columns have more in them it can lead to a bit more complexity. I think I've found a generalized solution for any number of cells in multiple columns.
#Goals Get a vertical sequence of tags on mobile to arrange themselves in whatever order the design calls for on tablet/desktop. In this concrete example, one tag must enter flow earlier than it normally would, and another later than it normally would.
##Mobile
[1 headline]
[2 image]
[3 qty]
[4 caption]
[5 desc]
##Tablet+
[2 image ][1 headline]
[ ][3 qty ]
[ ][5 desc ]
[4 caption][ ]
[ ][ ]
So headline needs to shuffle right on tablet+, and technically, so does desc - it sits above the caption tag that precedes it on mobile. You'll see in a moment 4 caption is in trouble too.
Let's assume every cell could vary in height, and needs to be flush top-to-bottom with its next cell (ruling out weak tricks like a table).
As with all Bootstrap Grid problems step 1 is to realize the HTML has to be in mobile-order, 1 2 3 4 5, on the page. Then, determine how to get tablet/desktop to reorder itself in this way - ideally without Javascript.
The solution to get 1 headline
and 3 qty
to sit to the right not the left is to simply set them both pull-right
. This applies CSS float: right
, meaning they find the first open space they'll fit to the right. You can think of the browser's CSS processor working in the following order: 1 fits in to the right top corner. 2 is next and is regular (float: left
), so it goes to top-left corner. Then 3, which is float: right
so it leaps over underneath 1.
But this solution wasn't enough for 4 caption
; because the right 2 cells are so short 2 image
on the left tends to be longer than the both of them combined. Bootstrap Grid is a glorified float hack, meaning 4 caption
is float: left
. With 2 image
occupying so much room on the left, 4 caption
attempts to fit in the next available space - often the right column, not the left where we wanted it.
The solution here (and more generally for any issue like this) was to add a hack tag, hidden on mobile, that exists on tablet+ to push caption out, that then gets covered up by a negative margin - like this:
[2 image ][1 headline]
[ ][3 qty ]
[ ][4 hack ]
[5 caption][6 desc ^^^]
[ ][ ]

So, the generalized solution here is to add hack tags that can disappear on mobile. On tablet+ the hack tags allow displayed tags to appear earlier or later in the flow, then get pulled up or down to cover up those hack tags.
Note: I've used fixed heights for the sake of the simple example in the linked jsfiddle, but the actual site content I was working on varies in height in all 5 tags. It renders properly with relatively large variance in tag heights, especially image and desc.
Note 2: Depending on your layout, you may have a consistent enough column order on tablet+ (or larger resolutions), that you can avoid use of hack tags, using margin-bottom
instead, like so:
Note 3: This uses Bootstrap 3. Bootstrap 4 uses a different grid set, and won't work with these examples.
You can also change the index name in column definitions within a create_table
block (such as you get from the migration generator).
create_table :studies do |t|
t.references :user, index: {:name => "index_my_shorter_name"}
end
gmdate()
is doing exactly what you asked for.
Look at formats here: http://php.net/manual/en/function.gmdate.php
In Java 8 you can use:
LocalDate date = LocalDate.now(); //2020-01-12
date.withDayOfMonth(1); //2020-01-01
A Collection
does not have an ordering, so wanting to sort it does not make sense. You can sort List
instances and arrays, and the methods to do that are Collections.sort()
and Arrays.sort()
Use HTML's anchors:
Main Page:
<a href="sample.html#sushi">Sushi</a>
<a href="sample.html#bbq">BBQ</a>
Sample Page:
<div id='sushi'><a name='sushi'></a></div>
<div id='bbq'><a name='bbq'></a></div>
You can also use the bin
function with method = "content"
from the OneR
package for that:
library(OneR)
das$wt_2 <- as.numeric(bin(das$wt, nbins = 3, method = "content"))
das
## anim wt wt_2
## 1 1 181.0 1
## 2 2 179.0 1
## 3 3 180.5 1
## 4 4 201.0 2
## 5 5 201.5 2
## 6 6 245.0 2
## 7 7 246.4 3
## 8 8 189.3 1
## 9 9 301.0 3
## 10 10 354.0 3
## 11 11 369.0 3
## 12 12 205.0 2
## 13 13 199.0 1
## 14 14 394.0 3
## 15 15 231.3 2
To answer the other half of the question, you can call:
return PartialView("viewname");
when you want to return partial HTML. You'll just have to find some way to decide whether the request wants JSON or HTML, perhaps based on a URL part/parameter.
You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.
Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String
'Assign data to first item in array
compArray(1) = "asdf"
'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"
'Prints "ErrorState"
Debug.Print Computers("Computer Name")
Collections cannot be sorted so if you need to sort data you will probably want to use an array.
Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx
Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx
Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!
Edit:
Sub ArrayExample()
Dim subject As String
Dim TestArray() As String
Dim counter As Long
subject = "Example"
counter = Len(subject)
ReDim TestArray(1 To counter) As String
For counter = 1 To Len(subject)
TestArray(counter) = Right(Left(subject, counter), 1)
Next
End Sub
stuff
is an object and push
is a method of an array. So you cannot use stuff.push(..)
.
Lets say you define stuff
as an array stuff = [];
then you can call push
method on it.
This works because the object[key/value] is well formed.
stuff.push( {'name':$(this).attr('checked')} );
Whereas this will not work because the object is not well formed.
stuff.push( {$(this).attr('value'):$(this).attr('checked')} );
This works because we are treating stuff
as an associative array and added values to it
stuff[$(this).attr('value')] = $(this).attr('checked');
I think easy way to disable button is :data => { disable_with: "Saving.." }
This will submit a form and then make a button disable, Also it won't disable button if you have any validations like required = 'required'.
Yes & No, but delegate pattern in Java could be thought of this way. This video tutorial is about data exchange between activity - fragments, and it has great essence of delegate sorta pattern using interfaces.
In addition to registering a ByteArrayHttpMessageConverter
, you may want to use a ResponseEntity
instead of @ResponseBody
. The following code works for me :
@RequestMapping("/photo2")
public ResponseEntity<byte[]> testphoto() throws IOException {
InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
final HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.IMAGE_PNG);
return new ResponseEntity<byte[]>(IOUtils.toByteArray(in), headers, HttpStatus.CREATED);
}
Following code will enumerate all values for a certain Registry key, will sort them and will return value name : value pairs separated by colon (:):
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework';
Get-Item -Path $path | Select-Object -ExpandProperty Property | Sort | % {
$command = [String]::Format('(Get-ItemProperty -Path "{0}" -Name "{1}")."{1}"', $path, $_);
$value = Invoke-Expression -Command $command;
$_ + ' : ' + $value; };
Like this:
DbgJITDebugLaunchSetting : 16
DbgManagedDebugger : "C:\Windows\system32\vsjitdebugger.exe" PID %d APPDOM %d EXTEXT "%s" EVTHDL %d
InstallRoot : C:\Windows\Microsoft.NET\Framework\
Check if you have multiple versions of the npm
command in your system path variable.
In my case, I had a version in the Node install directory and an older one in the npm globals
install directory (called prefix
in the npm config file). So I checked npm config get prefix
for the location and deleted the link and the npm
folder from node_modules. (Deleting the other one might also work, depending on the order in your PATH variable.)
In your statement, you are comparing a string called start_date with the time.
If start_date is a column, it should either be
SELECT * FROM `la_schedule` WHERE start_date >'2012-11-18';
(no apostrophe) or
SELECT * FROM `la_schedule` WHERE `start_date` >'2012-11-18';
(with backticks).
Hope this helps.
The immediate problem is due to you using <= temp.length()
instead of < temp.length()
. However, you can achieve this a lot more simply. Even if you use the string approach, you can use:
String temp = Integer.toString(guess);
int[] newGuess = new int[temp.length()];
for (int i = 0; i < temp.length(); i++)
{
newGuess[i] = temp.charAt(i) - '0';
}
You need to make the same change to use < newGuess.length()
when printing out the content too - otherwise for an array of length 4 (which has valid indexes 0, 1, 2, 3) you'll try to use newGuess[4]
. The vast majority of for
loops I write use <
in the condition, rather than <=
.
The current answer didn't work for me with Bootstrap 3.1.1. Here's what I had to override:
.form-control:focus {
border-color: inherit;
-webkit-box-shadow: none;
box-shadow: none;
}
For what it's worth - I had a similar issue, assuming it's related to a Chrome update.
I had to add font-src, and then specify the url because I was using a CDN
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; font-src 'self' data: fonts.gstatic.com;">
to use white space in xml as string use  
. XML won't take white space as it is. it will trim the white space before setting it. So use  
instead of single white space
During the installation you got a message
Composer successfully installed to: ...
this indicates where Composer was installed. But you might also search for the file composer.phar
on your system.
Then simply:
composer.phar
./home/<user>/.composer
C:\Users\<username>\AppData\Roaming\Composer
That's it.
You can see this error in VS 2008 if you have a project in your solution that references an assembly that cannot be found. This could happen if the assembly comes from another project that is not part of your solution but should be. In this case simply adding the correct project to the solution will solve it.
Check the References section of each project in your solution. If any of them has a reference with an red x next to it, then it you have found your problem. That assembly reference cannot be found by the solution.
The error message is a bit confusing but I've seen this many times.
at least pip3 also works without "=", however, instead of "http" you might need "https"
Final command, which worked for me:
sudo pip3 install --proxy https://{proxy}:{port} {BINARY}
You also will have to catch or throw the IOException. See below. Not always the best way, but it will get you a result:
public class details {
public static void main( String[] args) throws IOException {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);
}
}
Unrelated to the original question, but because this is the first Google result... I hit this on Google AppEngine and had to add:
libraries:
- name: ssl
version: latest
to app.yaml per: https://cloud.google.com/appengine/docs/python/sockets/ssl_support
Please NOTE: This seems to work upto Python version 2.7.9 but not for 2.7.10 or 2.7.11.
Set below code in RouteConfig.cs in App_Start folder
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });
}
IF still not working then do below steps
Second Way : You simple follow below steps,
1) Right click on your Project
2) Select Properties
3) Select Web option and then Select Specific Page (Controller/View) and then set your login page
Here, Account is my controller and Login is my action method (saved in Account Controller)
Please take a look attached screenshot.
If you are having an issue with your bin files due to a long path, In Visual Studio 2015 you can go to the offending project's property page and change the relative Output Directory to a shorter one.
E.g. bin\debug\ becomes C:\_bins\MyProject\
You can do it like this, but sorry my english is not good enough.
First, get home base url with this simple code..
I've tested this code on my local server and public and the result is good.
<?php
function home_base_url(){
// first get http protocol if http or https
$base_url = (isset($_SERVER['HTTPS']) &&
$_SERVER['HTTPS']!='off') ? 'https://' : 'http://';
// get default website root directory
$tmpURL = dirname(__FILE__);
// when use dirname(__FILE__) will return value like this "C:\xampp\htdocs\my_website",
//convert value to http url use string replace,
// replace any backslashes to slash in this case use chr value "92"
$tmpURL = str_replace(chr(92),'/',$tmpURL);
// now replace any same string in $tmpURL value to null or ''
// and will return value like /localhost/my_website/ or just /my_website/
$tmpURL = str_replace($_SERVER['DOCUMENT_ROOT'],'',$tmpURL);
// delete any slash character in first and last of value
$tmpURL = ltrim($tmpURL,'/');
$tmpURL = rtrim($tmpURL, '/');
// check again if we find any slash string in value then we can assume its local machine
if (strpos($tmpURL,'/')){
// explode that value and take only first value
$tmpURL = explode('/',$tmpURL);
$tmpURL = $tmpURL[0];
}
// now last steps
// assign protocol in first value
if ($tmpURL !== $_SERVER['HTTP_HOST'])
// if protocol its http then like this
$base_url .= $_SERVER['HTTP_HOST'].'/'.$tmpURL.'/';
else
// else if protocol is https
$base_url .= $tmpURL.'/';
// give return value
return $base_url;
}
?>
// and test it
echo home_base_url();
output will like this :
local machine : http://localhost/my_website/ or https://myhost/my_website
public : http://www.my_website.com/ or https://www.my_website.com/
use home_base_url
function at index.php
of your website and define it
and then you can use this function to load scripts, css and content via url like
<?php
echo '<script type="text/javascript" src="'.home_base_url().'js/script.js"></script>'."\n";
?>
will create output like this :
<script type="text/javascript" src="http://www.my_website.com/js/script.js"></script>
and if this script works fine,,!
This post was helpful, but just wanted to share a slight alternative that may help others:
Setting max-height
instead of height
also does the trick. In my case, I'm disabling scrolling based on a class toggle. Setting .someContainer {height: 100%; overflow: hidden;}
when the container's height is smaller than that of the viewport would stretch the container, which wouldn't be what you'd want. Setting max-height
accounts for this, but if the container's height is greater than the viewport's when the content changes, still disables scrolling.
I think you should only use ng-model and should work well for you, here is the link to the official documentation of angular https://docs.angularjs.org/api/ng/input/input%5Bradio%5D
The code from the example should not be difficult to adapt to your specific situation:
<script>
function Ctrl($scope) {
$scope.color = 'blue';
$scope.specialValue = {
"id": "12345",
"value": "green"
};
}
</script>
<form name="myForm" ng-controller="Ctrl">
<input type="radio" ng-model="color" value="red"> Red <br/>
<input type="radio" ng-model="color" ng-value="specialValue"> Green <br/>
<input type="radio" ng-model="color" value="blue"> Blue <br/>
<tt>color = {{color | json}}</tt><br/>
</form>
I know there's already a few answers here, but here is what I used:
max-width: 100%;
max-height: 100vh;
width: auto;
margin: auto;
Combining the answers into an overloaded set of functions (and using "**" instead of "^^" as some other languages use - clearer to me):
// http://stackoverflow.com/questions/24196689/how-to-get-the-power-of-some-integer-in-swift-language
// Put this at file level anywhere in your project
infix operator ** { associativity left precedence 160 }
func ** (radix: Double, power: Double) -> Double { return pow(radix, power) }
func ** (radix: Int, power: Int ) -> Double { return pow(Double(radix), Double(power)) }
func ** (radix: Float, power: Float ) -> Double { return pow(Double(radix), Double(power)) }
When using Float, you may lose precision. If using numeric literals and a mix of integers and non-integers, you will end up with Double by default. I personally like the ability to use a mathematical expression instead of a function like pow(a, b) for stylistic/readability reasons, but that's just me.
Any operators that would cause pow() to throw an error will also cause these functions to throw an error, so the burden of error checking still lies with the code using the power function anyway. KISS, IMHO.
Using the native pow() function allows to eg take square roots (2 ** 0.5) or inverse (2 ** -3 = 1/8). Because of the possibility to use inverse or fractional exponents, I wrote all my code to return the default Double type of the pow() function, which should return the most precision (if I remember the documentation correctly). If needed, this can be type-casted down to Int or Float or whatever, possibly with the loss of precision.
2 ** -3 = 0.125
2 ** 0.5 = 1.4142135623731
2 ** 3 = 8

If your into Python or use Androguard, the Androguard Androaxml feature will do this conversion for you. The feature is detailed in this blog post, with additional documentation here and source here.
Usage:
$ ./androaxml.py -h
Usage: androaxml.py [options]
Options:
-h, --help show this help message and exit
-i INPUT, --input=INPUT
filename input (APK or android's binary xml)
-o OUTPUT, --output=OUTPUT
filename output of the xml
-v, --version version of the API
$ ./androaxml.py -i yourfile.apk -o output.xml
$ ./androaxml.py -i AndroidManifest.xml -o output.xml
Use pass for no-op:
if x == 0:
pass
else:
print "x not equal 0"
And here's another example:
def f():
pass
Or:
class c:
pass
Regardless of what error Oracle SQL Developer may indicate in the syntax highlighting, actually running your alter
statement exactly the way you originally had it works perfectly:
ALTER TABLE TEST_PROJECT2 MODIFY proj_name VARCHAR2(300);
You only need to add parenthesis if you need to alter more than one column at once, such as:
ALTER TABLE TEST_PROJECT2 MODIFY (proj_name VARCHAR2(400), proj_desc VARCHAR2(400));

Updated July 2016
As of July 2016, the Download ZIP button has moved under Clone or download to extreme-right of header under the Code tab:
If you don't see the button:
Repo may not have a zip prepared. Add /archive/master.zip
to the end of the repository URL and to generate a zipfile of the master branch.
-to-
http://github.com/user/repository/archive/master.zip
to get the master branch source code in a zip file. You can do the same with tags and branch names, by replacing master
in the URL above with the name of the branch or tag.
This is largely a duplicate of another question.
Here's the section of that answer that is relevant to this question:
Do I need to do my own synchronization if I use java.util.ConcurrentLinkedQueue?
Atomic operations on the concurrent collections are synchronized for you. In other words, each individual call to the queue is guaranteed thread-safe without any action on your part. What is not guaranteed thread-safe are any operations you perform on the collection that are non-atomic.
For example, this is threadsafe without any action on your part:
queue.add(obj);
or
queue.poll(obj);
However; non-atomic calls to the queue are not automatically thread-safe. For example, the following operations are not automatically threadsafe:
if(!queue.isEmpty()) {
queue.poll(obj);
}
That last one is not threadsafe, as it is very possible that between the time isEmpty is called and the time poll is called, other threads will have added or removed items from the queue. The threadsafe way to perform this is like this:
synchronized(queue) {
if(!queue.isEmpty()) {
queue.poll(obj);
}
}
Again...atomic calls to the queue are automatically thread-safe. Non-atomic calls are not.
Try using copy()
function instead of move_uploaded_file()
. It worked for me.
copy($_FILES['file']['tmp_name'], $path);
Let me expand a bit on a VonC's very comprehensive answer:
First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.
Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".
Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

Compile time polymorphism(Static Binding/Early Binding): In static polymorphism, if we call a method in our code then which definition of that method is to be called actually is resolved at compile time only.
(or)
At compile time, Java knows which method to invoke by checking the method signatures. So, this is called compile-time polymorphism or static binding.
Dynamic Polymorphism(Late Binding/ Runtime Polymorphism): At run time, Java waits until runtime to determine which object is actually being pointed to by the reference. Method resolution was taken at runtime, due to that we call as run time polymorphism.
Sometimes it's convenient to use UNICODE partial spaces to achieve alignment while prototyping. This can be handy in prototyping, proof-of-concept, or just to defer implementation of graphics algorithms.
If you use UNICODE spaces for convenience, be aware that at least one of the UNICODE spaces has a size based on the font it is displayed from, specifically the actual space character itself (U+0020, ASCII 32)
If you're using the default iOS system font in a UILabel, the default System font characteristics could change in a subsequent iOS release and suddenly introduce an unwanted misalignment by changing your app's precise spacing. This can and does happen, for example the "San Francisco" font replaced a previous iOS system font in an iOS release.
UNICODE easy to specify in Swift, for example:
let six_per_em_space = "\u{2006}"
Alternatively, cut/paste the space from an HTML page directly into the UILabel's text field in Interface Builder.
Note: Attached pic is a screenshot, not HTML, so visit the linked page if you want to cut/paste the space.
You may want to take a look at those pages : http://developer.android.com/reference/android/os/Build.html and http://developer.android.com/reference/java/lang/System.html (the getProperty() method might do the job).
For instance :
System.getProperty("os.version"); // OS version
android.os.Build.VERSION.SDK // API Level
android.os.Build.DEVICE // Device
android.os.Build.MODEL // Model
android.os.Build.PRODUCT // Product
Etc...

-H/--header <header>
(HTTP) Extra header to use when getting a web page. You may specify
any number of extra headers. Note that if you should add a custom
header that has the same name as one of the internal ones curl would
use, your externally set header will be used instead of the internal
one. This allows you to make even trickier stuff than curl would
normally do. You should not replace internally set headers without
knowing perfectly well what you're doing. Remove an internal header
by giving a replacement without content on the right side of the
colon, as in: -H "Host:".
curl will make sure that each header you add/replace get sent with
the proper end of line marker, you should thus not add that as a
part of the header content: do not add newlines or carriage returns
they will only mess things up for you.
See also the -A/--user-agent and -e/--referer options.
This option can be used multiple times to add/replace/remove multi-
ple headers.
curl --header "X-MyHeader: 123" www.google.com
You can see the request that curl sent by adding the -v
option.
The size of array must be greater than zero. ?therwise you will have unexpected results.

From what I understand, you have your data on a table and you want to create the CSV from that data. However, you have problem creating the CSV.
My thoughts would be to iterate and parse the contents of the table and generate a string from the parsed data. You can check How to convert JSON to CSV format and store in a variable for an example. You are using jQuery in your example so that would not count as an external plugin. Then, you just have to serve the resulting string using window.open
and use application/octetstream
as suggested.
check the round function and how does the length
argument works. It controls the behaviour of the precision of the result
Try this:-
private String getWhoozitYs(){
StringBuffer sb = new StringBuffer();
boolean stop = generator.nextBoolean();
if(stop)
{
sb.append("y");
getWhoozitYs();
}
return sb.toString();
}
Are you calling getWidth()
before the view is actually laid out on the screen?
A common mistake made by new Android developers is to use the width and height of a view inside its constructor. When a view’s constructor is called, Android doesn’t know yet how big the view will be, so the sizes are set to zero. The real sizes are calculated during the layout stage, which occurs after construction but before anything is drawn. You can use the
onSizeChanged()
method to be notified of the values when they are known, or you can use thegetWidth()
andgetHeight()
methods later, such as in theonDraw()
method.
The loop in your code is only an over-simplified example, right?
It would be better to create the PreparedStatement
only once, and re-use it over and over again in the loop.
In situations where that is not possible (because it complicated the program flow too much), it is still beneficial to use a PreparedStatement
, even if you use it only once, because the server-side of the work (parsing the SQL and caching the execution plan), will still be reduced.
To address the situation that you want to re-use the Java-side PreparedStatement
, some JDBC drivers (such as Oracle) have a caching feature: If you create a PreparedStatement
for the same SQL on the same connection, it will give you the same (cached) instance.
About multi-threading: I do not think JDBC connections can be shared across multiple threads (i.e. used concurrently by multiple threads) anyway. Every thread should get his own connection from the pool, use it, and return it to the pool again.
This part of code worked fine for me:
WebRequest request = WebRequest.Create(url);
request.Method = WebRequestMethods.Http.Get;
NetworkCredential networkCredential = new NetworkCredential(logon, password); // logon in format "domain\username"
CredentialCache myCredentialCache = new CredentialCache {{new Uri(url), "Basic", networkCredential}};
request.PreAuthenticate = true;
request.Credentials = myCredentialCache;
using (WebResponse response = request.GetResponse())
{
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
using (Stream dataStream = response.GetResponseStream())
{
using (StreamReader reader = new StreamReader(dataStream))
{
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
}
}
}
Basically, this way you combine things because jQuery is a framework which mostly focuses on HTML elements, you basically preventing the default, but at the same time, you stop propagation to bubble up.
So we can simply say, return false in jQuery
is equal to:
return false is e.preventDefault AND e.stopPropagation
But also don't forget it's all in jQuery or DOM related functions, when you run it on the element, basically, it prevents everything from firing including the default behaviour and propagation of the event.
Basically before starting using return false;
, first understand what e.preventDefault();
and e.stopPropagation();
do, then if you think you need both at the same time, then simply use it.
So basically this code below:
$('div').click(function () {
return false;
});
is equal to this code:
$('div').click(function (event) {
event.preventDefault();
event.stopPropagation();
});
For JavaScript arrays, you use Both push() and concat() function.
var array = [1, 2, 3];
array.push(4, 5); //use push for appending a single array.
var array1 = [1, 2, 3];
var array2 = [4, 5, 6];
var array3 = array1.concat(array2); //It is better use concat for appending more then one array.
In simple words, if your client/user can recover from the Exception then make it a Checked Exception, if your client can't do anything to recover from the Exception then make it Unchecked RuntimeException. E.g, a RuntimeException would be a programmatic error, like division by zero, no user can do anything about it but the programmer himself, then it is a RuntimeException.
This question is quite old but here goes anyway. If you're trying to get just the previous month and the day does not matter you can use this:
$date = '2014-01-03';
$dateTime = new DateTime($date);
$lastMonth = $dateTime->modify('-' . $dateTime->format('d') . ' days')->format('F Y');
echo $lastMonth; // 'December 2013'
it should be like that,
$this->db->select('*');
$this->db->from('table1');
$this->db->join('table2', 'table1.id = table2.id');
$this->db->join('table3', 'table1.id = table3.id');
$query = $this->db->get();
as per CodeIgniters active record framework
This is explained well in the Python FAQ
What are the rules for local and global variables in Python?
In Python, variables that are only referenced inside a function are implicitly global. If a variable is assigned a value anywhere within the function’s body, it’s assumed to be a local unless explicitly declared as global.
Though a bit surprising at first, a moment’s consideration explains this. On one hand, requiring
global
for assigned variables provides a bar against unintended side-effects. On the other hand, ifglobal
was required for all global references, you’d be usingglobal
all the time. You’d have to declare asglobal
every reference to a built-in function or to a component of an imported module. This clutter would defeat the usefulness of theglobal
declaration for identifying side-effects.

Use the following instead:
boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );
This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.
Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

If you want to hide the cursor in the entire webpage, using body
will not work unless it covers the entire visible page, which is not always the case. To make sure the cursor is hidden everywhere in the page, use:
document.documentElement.style.cursor = 'none';
To reenable it:
document.documentElement.style.cursor = 'auto';
The analogue with static CSS notation is in the answer by Pavel Salaquarda (in essence: html * {cursor:none}
)
Best practice says to implement it by your own using local boolean field: http://www.niedermann.dk/2009/06/18/BestPracticeDisposePatternC.aspx

Finding of week number for each date of a month (considering Monday as beginning of the week)
Keep the first date of month contant $B$13
=WEEKNUM(B18,2)-WEEKNUM($B$13,2)+1
WEEKNUM(B18,2)
- returns the week number of the date mentioned in cell B18
WEEKNUM($B$13,2)
- returns the week number of the 1st date of month in cell B13
Possible reasons are 1. you didn't load React.JS into your page, 2. you loaded it after the above script into your page. Solution is load the JS file before the above shown script.
P.S
Possible solutions.

If using the Gitlab Docker image:
sudo cat /srv/gitlab/data/gitlab-rails/VERSION
Example output:

you can use the tag pattern:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *identifier = @"identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
[cell autorelelase];
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(10, 5, 40, 20)];
[button addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTag:[indexPath row]]; //use the row as the current tag
[cell.contentView addSubview:button];
[button release];
}
UIButton *button = (UIButton *)[cell viewWithTag:[indexPath row]]; //use [indexPath row]
[button setTitle:@"Edit" forState:UIControlStateNormal];
return cell;
}
- (void)buttonPressedAction:(id)sender
{
UIButton *button = (UIButton *)sender;
//button.tag has the row number (you can convert it to indexPath)
}
Your ProcExit label is your place where you release all the resources whether an error happened or not. For instance:
Public Sub SubA()
On Error Goto ProcError
Connection.Open
Open File for Writing
SomePreciousResource.GrabIt
ProcExit:
Connection.Close
Connection = Nothing
Close File
SomePreciousResource.Release
Exit Sub
ProcError:
MsgBox Err.Description
Resume ProcExit
End Sub
This was the only reasonable thing I found to fade a background image.
<div id="foo">
<!-- some content here -->
</div>
Your CSS; now enhanced with CSS3 transition.
#foo {
background-image: url(a.jpg);
transition: background 1s linear;
}
Now swap out the background
document.getElementById("foo").style.backgroundImage = "url(b.jpg)";
Voilà, it fades!
Obvious disclaimer: if your browser doesn't support the CSS3 transition
property, this won't work. In which case, the image will change without a transition. Given <1%
of your users' browser don't support CSS3, that's probably fine. Don't kid yourself, it's fine.
The official instructions seem to be here: https://docs.anaconda.com/anaconda/install/uninstall/
but if you like me that didn't work for some reason and for some reason your conda was installed somewhere else with telling you do this:
rm -rf ~/opt
I have no idea why it was saved there but that's what did it for me.
This was useful to me in fixing my conda installation (if that is the reason you are uninstalling it in the first place like me): https://stackoverflow.com/a/60902863/1601580 that ended up fixing it for me. Not sure why conda was acting weird in the first place or installing things wrongly in the first place though...
I've recently stumbled upon the following solution to this problem:
Source: Multiple versions of Chrome
...this is registry data problem: How to do it then (this is an example for 2.0.172.39 and 3.0.197.11, I'll try it with next versions as they will come, let's assume I've started with Chrome 2):
Install Chrome 2, you'll find it
Application Data
folder, since I'm from Czech Republic and my name is Bronislav Klucka the path looks like this:C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome
and run Chrome
Open registry and save
[HKEY_CURRENT_USER\Software\Google\Update\Clients\{8A69D345-D564-463c-AFF1-A69D9E530F96}] [HKEY_CURRENT_USER\Software\Google\Update\ClientState\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
keys, put them into one chrome2.reg file and copy this file next to
chrome.exe
(ChromeDir\Application)Rename Chrome folder to something else (e.g. Chrome2)
Install Chrome 3, it will install to Chrome folder again and run Chrome
- Save the same keys (there are changes due to different version) and save it to the
chrome3.reg
file next tochrome.exe
file of this new version againRename the folder again (e.g. Chrome3)
the result would be that there is no Chrome dir (only Chrome2 and Chrome3)
Go to the Application folder of Chrome2, create
chrome.bat
file with this content:@echo off regedit /S chrome2.reg START chrome.exe -user-data-dir="C:\Docume~1\Bronis~1\LocalS~1\Dataap~1\Google\Chrome2\User Data" rem START chrome.exe -user-data-dir="C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome2\User Data"
the first line is generic batch command, the second line will update registry with the content of
chrome2.reg
file, the third lines starts Chrome pointing to passed directory, the 4th line is commented and will not be run.Notice short name format passed as
-user-data-dir
parameter (the full path is at the 4th line), the problem is that Chrome using this parameter has a problem with diacritics (Czech characters)Do 7. again for Chrome 3, update paths and reg file name in bat file for Chrome 3
Try running both bat files, seems to be working, both versions of Chrome are running simultaneously.
Updating: Running "About" dialog displays correct version, but an error while checking for new one. To correct that do (I'll explain form Chrome2 folder): 1. rename Chrome2 to Chrome 2. Go to Chrome/Application folder 3. run chrome2.reg file 4. run chrome.exe (works the same for Chrome3) now the version checking works. There has been no new version of Chrome since I've find this whole solution up. But I assume that update will be downloaded to this folder so all you need to do is to update reg file after update and rename Chrome folder back to Chrome2. I'll update this post after successful Chrome update.

The date format for mysql insert query is YYYY-MM-DD
example:
INSERT INTO table_name (date_column) VALUE ('YYYY-MM-DD');
You guess correctly. Read the manual page for move_uploaded_file
. Set the second parameter to whereever your want to save the file.
If it doesn't work, there is something wrong with your $fileName
. Please post your most recent code.
This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.
In standard SQL one would write:
SELECT t0.foo, t1.bar
FROM FIRST_TABLE t0
RIGHT OUTER JOIN SECOND_TABLE t1;
Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :
Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]
You would have to use the JavascriptExecutor class:

I have some code in my game that displays live score. It is in a function for quick access.
def texts(score):
font=pygame.font.Font(None,30)
scoretext=font.render("Score:"+str(score), 1,(255,255,255))
screen.blit(scoretext, (500, 457))
and I call it using this in my while loop:
texts(score)
UPDATE: For Bootstrap 5
The class name is now "float-end" instead of "pull-right"
<div class="alert alert-info clearfix">
<a href="#" class="alert-link">
Summary:Its some description.......testtesttest
</a>
<button type="button" class="btn btn-primary btn-lg float-end">
Large button
</button>
</div>
For Bootstrap 4 and under
Just add a simple pull-right class to the button, and make sure the container div is clearfixed:
<div class="alert alert-info clearfix">
<a href="#" class="alert-link">
Summary:Its some description.......testtesttest
</a>
<button type="button" class="btn btn-primary btn-lg pull-right">
Large button
</button>
</div>
do a AutoResetEvent, call the function then wait on AutoResetEvent and then set it inside async void when you know it is done.
You can also wait on a Task that returns from your void async
If you want to check if two arrays have the same shape
AND elements
you should use np.array_equal
as it is the method recommended in the documentation.
Performance-wise don't expect that any equality check will beat another, as there is not much room to optimize
comparing two elements
. Just for the sake, i still did some tests.
import numpy as np
import timeit
A = np.zeros((300, 300, 3))
B = np.zeros((300, 300, 3))
C = np.ones((300, 300, 3))
timeit.timeit(stmt='(A==B).all()', setup='from __main__ import A, B', number=10**5)
timeit.timeit(stmt='np.array_equal(A, B)', setup='from __main__ import A, B, np', number=10**5)
timeit.timeit(stmt='np.array_equiv(A, B)', setup='from __main__ import A, B, np', number=10**5)
> 51.5094
> 52.555
> 52.761
So pretty much equal, no need to talk about the speed.
The (A==B).all()
behaves pretty much as the following code snippet:
x = [1,2,3]
y = [1,2,3]
print all([x[i]==y[i] for i in range(len(x))])
> True
I believe the admin button will open the default configuration always. It simply contains a link to localhost/xampp
and it doesn't read the server configuration.
If you change the default settings, you know what you changed and you can enter the URL directly in the browser.
The simplest solution as the support of Element.getBoundingClientRect() has become perfect:
function isInView(el) {
let box = el.getBoundingClientRect();
return box.top < window.innerHeight && box.bottom >= 0;
}
Two ways to get this done:
Collections.sort(myArray)
given elements inside myArray implements Comparable
Second
Collections.sort(myArray, new MyArrayElementComparator());
where MyArrayElementComparator
is Comparator
for elements inside myArray
I always use pseudo elements :before

Use this for legacy code (PHP < 5.3). For up to date solution see jurka's answer below
You can use strtotime() to convert two dates to unix time and then calculate the number of seconds between them. From this it's rather easy to calculate different time periods.
$date1 = "2007-03-24";
$date2 = "2009-06-26";
$diff = abs(strtotime($date2) - strtotime($date1));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
printf("%d years, %d months, %d days\n", $years, $months, $days);
Edit: Obviously the preferred way of doing this is like described by jurka below. My code is generally only recommended if you don't have PHP 5.3 or better.
Several people in the comments have pointed out that the code above is only an approximation. I still believe that for most purposes that's fine, since the usage of a range is more to provide a sense of how much time has passed or remains rather than to provide precision - if you want to do that, just output the date.
Despite all that, I've decided to address the complaints. If you truly need an exact range but haven't got access to PHP 5.3, use the code below (it should work in PHP 4 as well). This is a direct port of the code that PHP uses internally to calculate ranges, with the exception that it doesn't take daylight savings time into account. That means that it's off by an hour at most, but except for that it should be correct.

For two strings concat is faster, in other cases StringBuilder is a better choice, see my explanation in concatenation operator (+) vs concat()
There is no guarantee that your threads are executing simultaneously regardless of any trivial example anyone else posts. If your OS only gives the java process one processor to work on, your java threads will still be scheduled for each time slice in a round robin fashion. Meaning, no two will ever be executing simultaneously, but the work they do will be interleaved. You can use monitoring tools like Java's Visual VM (standard in the JDK) to observe the threads executing in a Java process.
This uses the above ideas but makes it a derived 'more sensitive' collection:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using System.Collections.ObjectModel;
using System.Collections.Specialized;
using System.Collections;
namespace somethingelse
{
public class ObservableCollectionEx<T> : ObservableCollection<T> where T : INotifyPropertyChanged
{
// this collection also reacts to changes in its components' properties
public ObservableCollectionEx() : base()
{
this.CollectionChanged +=new System.Collections.Specialized.NotifyCollectionChangedEventHandler(ObservableCollectionEx_CollectionChanged);
}
void ObservableCollectionEx_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
if (e.Action == NotifyCollectionChangedAction.Remove)
{
foreach(T item in e.OldItems)
{
//Removed items
item.PropertyChanged -= EntityViewModelPropertyChanged;
}
}
else if (e.Action == NotifyCollectionChangedAction.Add)
{
foreach(T item in e.NewItems)
{
//Added items
item.PropertyChanged += EntityViewModelPropertyChanged;
}
}
}
public void EntityViewModelPropertyChanged(object sender, PropertyChangedEventArgs e)
{
//This will get called when the property of an object inside the collection changes - note you must make it a 'reset' - I don't know, why
NotifyCollectionChangedEventArgs args = new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset);
OnCollectionChanged(args);
}
}
}
the command to get the effective push remote for the branch, e.g., master, is:
git config branch.master.pushRemote || git config remote.pushDefault || git config branch.master.remote
Here's why (from the "man git config" output):
branch.name.remote [...] tells git fetch and git push which remote to fetch from/push to [...] [for push] may be overridden with remote.pushDefault (for all branches) [and] for the current branch [..] further overridden by branch.name.pushRemote [...]
For some reason, "man git push" only tells about branch.name.remote (even though it has the least precedence of the three) + erroneously states that if it is not set, push defaults to origin - it does not, it's just that when you clone a repo, branch.name.remote is set to origin, but if you remove this setting, git push will fail, even though you still have the origin remote
You can solve the problem by checking if your date matches a REGEX pattern. If not, then NULL (or something else you prefer).
In my particular case it was necessary because I have >20 DATE columns saved as CHAR, so I don't know from which column the error is coming from.
Returning to your query:
1. Declare a REGEX pattern.
It is usually a very long string which will certainly pollute your code (you may want to reuse it as well).
define REGEX_DATE = "'your regex pattern goes here'"
Don't forget a single quote inside a double quote around your Regex :-)
A comprehensive thread about Regex date validation you'll find here.
2. Use it as the first CASE condition:
To use Regex validation in the SELECT
statement, you cannot use REGEXP_LIKE
(it's only valid in WHERE
. It took me a long time to understand why my code was not working. So it's certainly worth a note.
Instead, use REGEXP_INSTR
For entries not found in the pattern (your case) use REGEXP_INSTR (variable, pattern) = 0
.
DEFINE REGEX_DATE = "'your regex pattern goes here'"
SELECT c.contract_num,
CASE
WHEN REGEXP_INSTR(c.event_dt, ®EX_DATE) = 0 THEN NULL
WHEN ( MAX (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
- MIN (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
/ COUNT (c.event_occurrence) < 32
THEN
'Monthly'
WHEN ( MAX (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
- MIN (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
/ COUNT (c.event_occurrence) >= 32
AND ( MAX (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
- MIN (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
/ COUNT (c.event_occurrence) < 91
THEN
'Quarterley'
ELSE
'Yearly'
END
FROM ps_ca_bp_events c
GROUP BY c.contract_num;
This is a fix for a pretty niche use case but it gets me each time. If you are using the Eclipse Jaxb generator it creates a file called package-info.
@javax.xml.bind.annotation.XmlSchema(namespace = "blah.xxx.com/em/feed/v2/CommonFeed")
package xxx.blah.mh.domain.pl3xx.startstop;
If you delete this file it will allow a more generic xml to be parsed. Give it a try!
Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").

This can be accomplished by Unmarshaling into a map[string]json.RawMessage
.
var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)
To further parse sendMsg
, you could then do something like:
var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)
For say
, you can do the same thing and unmarshal into a string:
var str string
err = json.Unmarshal(objmap["say"], &str)
EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:
type sendMsg struct {
User string
Msg string
}
It works for me, try it.
for /f "tokens=* delims=;" %g in ('echo %PATH%') do echo %g%
It isn't giving any errors?
Try
SET @tmpType = 'premium
'
and
SET @tmpType = 'basic'
Short answer in bolds:
collect
is mainly to serialize
(loss of parallelism preserving all other data characteristics of the dataframe)
For example with a PrintWriter pw
you can't do direct df.foreach( r => pw.write(r) )
, must to use collect
before foreach
, df.collect.foreach(etc)
.
PS: the "loss of parallelism" is not a "total loss" because after serialization it can be distributed again to executors.
select
is mainly to select columns, similar to projection in relational algebra
(only similar in framework's context because Spark select
not deduplicate data).
So, it is also a complement of filter
in the framework's context.
Commenting explanations of other answers: I like the Jeff's classification of Spark operations in transformations (as select
) and actions (as collect
). It is also good remember that transforms (including select
) are lazily evaluated.
One cannot disable the browser back button functionality. The only thing that can be done is prevent them.
The below JavaScript code needs to be placed in the head section of the page where you don’t want the user to revisit using the back button:
<script>
function preventBack() {
window.history.forward();
}
setTimeout("preventBack()", 0);
window.onunload = function() {
null
};
</script>
Suppose there are two pages Page1.php
and Page2.php
and Page1.php
redirects to Page2.php
.
Hence to prevent user from visiting Page1.php
using the back button you will need to place the above script in the head section of Page1.php
.
For more information: Reference
The working directory is a common concept across virtually all operating systems and program languages etc. It's the directory in which your program is running. This is usually (but not always, there are ways to change it) the directory the application is in.
Relative paths are ones that start without a drive specifier. So in linux they don't start with a /
, in windows they don't start with a C:\
, etc. These always start from your working directory.
Absolute paths are the ones that start with a drive (or machine for network paths) specifier. They always go from the start of that drive.
std::string some_str = SOME_VAL;
if ( some_str.size() > 0 && some_str[some_str.length()-1] == '\n' )
some_str.resize( some_str.length()-1 );
or (removes several newlines at the end)
some_str.resize( some_str.find_last_not_of(L"\n")+1 );

For the people looking for regular polygons:
function regPolyPath(r,p,ctx){ //Radius, #points, context
//Azurethi was here!
ctx.moveTo(r,0);
for(i=0; i<p+1; i++){
ctx.rotate(2*Math.PI/p);
ctx.lineTo(r,0);
}
ctx.rotate(-2*Math.PI/p);
}
Use:
//Get canvas Context
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.translate(60,60); //Moves the origin to what is currently 60,60
//ctx.rotate(Rotation); //Use this if you want the whole polygon rotated
regPolyPath(40,6,ctx); //Hexagon with radius 40
//ctx.rotate(-Rotation); //remember to 'un-rotate' (or save and restore)
ctx.stroke();
For React.js, you can do this with more readable code. Hope it helps.
