Using 2.7:
from functools import partial
from random import randint
for roll in iter(partial(randint, 1, 8), 1):
print 'you rolled: {}'.format(roll)
print 'oops you rolled a 1!'
you rolled: 7
you rolled: 7
you rolled: 8
you rolled: 6
you rolled: 8
you rolled: 5
oops you rolled a 1!
Then change the "oops" print to a raise SystemExit
Model.select(:rating)
The result of this is a collection of Model
objects. Not plain ratings. And from uniq
's point of view, they are completely different. You can use this:
Model.select(:rating).map(&:rating).uniq
or this (most efficient):
Model.uniq.pluck(:rating)
Model.distinct.pluck(:rating)
Apparently, as of rails 5.0.0.1, it works only on "top level" queries, like above. Doesn't work on collection proxies ("has_many" relations, for example).
Address.distinct.pluck(:city) # => ['Moscow']
user.addresses.distinct.pluck(:city) # => ['Moscow', 'Moscow', 'Moscow']
In this case, deduplicate after the query
user.addresses.pluck(:city).uniq # => ['Moscow']
You can use CURL for this purpose see the example code:
$url = "your url";
$content = json_encode("your data to be sent");
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ( $status != 201 ) {
die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}
curl_close($curl);
$response = json_decode($json_response, true);
If you have a relatively- (or otherwise-) positioned div you can center something inside it with margin:auto
Vertical centering is a bit tricker, but possible.
you don't have a bitbucket password because you log with google, but you can "reset" the password here https://bitbucket.org/account/password/reset/
you will receive an email to setup a new password and that's it.
This is one of those things that can be difficult to search for if you don't already know where to look.
[
is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.
There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.
[
is equivalent to the test
command, except that [
requires ]
as its last argument, and test
does not.
Assuming the bash documentation is installed on your system, if you type info bash
and search for 'test'
or '['
(the apostrophes are part of the search), you'll find the documentation for the [
command, also known as the test
command. If you use man bash
instead of info bash
, search for ^ *test
(the word test
at the beginning of a line, following some number of spaces).
Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne
, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, !=
is the string inequality operator.
You can also find bash documentation on the web.
test
and [
)-ne
is under "arg1 OP arg2")test
The official definition of the test
command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).
if (!"success".equals(statusCheck))
Expanding this answer, one could further write a function that returns TRUE/FALSE based on whether or not a table exists:
CREATE FUNCTION fn_table_exists(dbName VARCHAR(255), tableName VARCHAR(255))
RETURNS BOOLEAN
BEGIN
DECLARE totalTablesCount INT DEFAULT (
SELECT COUNT(*)
FROM information_schema.TABLES
WHERE (TABLE_SCHEMA COLLATE utf8_general_ci = dbName COLLATE utf8_general_ci)
AND (TABLE_NAME COLLATE utf8_general_ci = tableName COLLATE utf8_general_ci)
);
RETURN IF(
totalTablesCount > 0,
TRUE,
FALSE
);
END
;
SELECT fn_table_exists('development', 'user');
I used declare methods with the public
modifier, because it makes the code more readable, especially with syntax highlighting. In our latest project though, we used Checkstyle which shows a warning with the default configuration for public
modifiers on interface methods, so I switched to ommitting them.
So I'm not really sure what's best, but one thing I really don't like is using public abstract
on interface methods. Eclipse does this sometimes when refactoring with "Extract Interface".
I met it when import a ViewController.m in TableViewController. Try to delete '#import "ViewController.m"' if it exited. Hope this help!
You would do something like this to get the path "Data\ich_will.mp3" inside your application environments folder.
string fileName = "ich_will.mp3";
string path = Path.Combine(Environment.CurrentDirectory, @"Data\", fileName);
In my case it would return the following:
C:\MyProjects\Music\MusicApp\bin\Debug\Data\ich_will.mp3
I use Path.Combine
and Environment.CurrentDirectory
in my example. These are very useful and allows you to build a path based on the current location of your application. Path.Combine
combines two or more strings to create a location, and Environment.CurrentDirectory
provides you with the working directory of your application.
The working directory is not necessarily the same path as where your executable
is located, but in most cases it should be, unless specified otherwise.
setTimout
executes outside of angular. You need to use $timeout
service for this to work:
var app = angular.module('test', []);
app.controller('TestCtrl', function ($scope, $timeout) {
$scope.testValue = 0;
$timeout(function() {
console.log($scope.testValue++);
}, 500);
});
The reason is that two-way binding in angular uses dirty checking. This is a good article to read about angular's dirty checking. $scope.$apply()
kicks off a $digest
cycle. This will apply the binding. $timeout
handles the $apply
for you so it is the recommended service to use when using timeouts.
Essentially, binding happens during the $digest
cycle (if the value is seen to be different).
If you use homebrew cask, you can do
brew cask install android-sdk
mkdir ~/Library/Android/sdk/tools
ln -s /usr/local/bin/ ~/Library/Android/sdk/tools/bin
flutter doctor --android-licenses
= """" & A1 & """"
Public Function Enquote(cell As Range, Optional quoteCharacter As String = """") As Variant
Enquote = quoteCharacter & cell.value & quoteCharacter
End Function
=OfficePersonal.xls!Enquote(A1)
=OfficePersonal.xls!Enquote(A1, "'")
To get permanent quoted strings, you will have to copy formula values and paste-special-values.
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()

There are a few good answers posted here, but I think you can simplify your code and skip the check for inputElement.selectionStart
support: it is not supported only on IE8 and earlier (see documentation) which represents less than 1% of the current browser usage.
var input = document.getElementById('myinput'); // or $('#myinput')[0]
var caretPos = input.selectionStart;
// and if you want to know if there is a selection or not inside your input:
if (input.selectionStart != input.selectionEnd)
{
var selectionValue =
input.value.substring(input.selectionStart, input.selectionEnd);
}
Based on Teste's code .. I can confirm the following works. I can't say whether or not this is "good" code, but it certainly works and could get you back up and running quickly if you ended up with GCM to FCM server problems!

this is how you do it if you want to listen for the "Enter" key. There is an onKeydown prop that you can use and you can read about it in react doc
and here is a codeSandbox
const App = () => {
const something=(event)=> {
if (event.keyCode === 13) {
console.log('enter')
}
}
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<input type='text' onKeyDown={(e) => something(e) }/>
</div>
);
}
You can do this :
df <- data.frame("a" = c(1,2,3,4), "b" = c(4,3,2,1), "x_ind" = c(1,0,1,1), "y_ind" = c(0,0,1,1), "z_ind" = c(0,1,1,1) )
df %>% mutate( bi = ifelse((df$x_ind + df$y_ind +df$z_ind)== 3, 1,0 ))
Perhaps a nice idiom for declaring constants for a class in Swift is to just use a struct named MyClassConstants like the following.
struct MyClassConstants{
static let testStr = "test"
static let testStrLength = countElements(testStr)
static let arrayOfTests: [String] = ["foo", "bar", testStr]
}
In this way your constants will be scoped within a declared construct instead of floating around globally.
I've added a static array constant, in response to a comment asking about static array initialization. See Array Literals in "The Swift Programming Language".
Notice that both string literals and the string constant can be used to initialize the array. However, since the array type is known the integer constant testStrLength
cannot be used in the array initializer.
The brief difference in layman's term is:

I'm assuming you're using jquery to make the AJAX call so you can do this pretty easily by putting the redirect in the success like so:
$.ajax({
url: 'ajax_location.html',
success: function(data) {
//this is the redirect
document.location.href='/newpage/';
}
});
Can't you just set left
to 50%
and then have margin-left
set to -25px
to account for it's width: http://jsfiddle.net/9AbYc/
.hero:after {
content:'';
position: absolute;
top: 100%;
left: 50%;
margin-left: -50px;
width: 0;
height: 0;
border-top: solid 50px #e15915;
border-left: solid 50px transparent;
border-right: solid 50px transparent;
}
or if you needed a variable width you could use: http://jsfiddle.net/9AbYc/1/
.hero:after {
content:'';
position: absolute;
top: 100%;
left: 0;
right: 0;
margin: 0 auto;
width: 0;
height: 0;
border-top: solid 50px #e15915;
border-left: solid 50px transparent;
border-right: solid 50px transparent;
}

For primitive types (including bytes), use System.Buffer.BlockCopy
instead of System.Array.Copy
. It's faster.
I timed each of the suggested methods in a loop executed 1 million times using 3 arrays of 10 bytes each. Here are the results:
System.Array.Copy
- 0.2187556 secondsSystem.Buffer.BlockCopy
- 0.1406286 secondsI increased the size of each array to 100 elements and re-ran the test:
System.Array.Copy
- 0.2812554 secondsSystem.Buffer.BlockCopy
- 0.2500048 secondsI increased the size of each array to 1000 elements and re-ran the test:
System.Array.Copy
- 1.0781457 secondsSystem.Buffer.BlockCopy
- 1.0156445 secondsFinally, I increased the size of each array to 1 million elements and re-ran the test, executing each loop only 4000 times:
System.Array.Copy
- 13.4533833 secondsSystem.Buffer.BlockCopy
- 13.1096267 secondsSo, if you need a new byte array, use
byte[] rv = new byte[a1.Length + a2.Length + a3.Length];
System.Buffer.BlockCopy(a1, 0, rv, 0, a1.Length);
System.Buffer.BlockCopy(a2, 0, rv, a1.Length, a2.Length);
System.Buffer.BlockCopy(a3, 0, rv, a1.Length + a2.Length, a3.Length);
But, if you can use an IEnumerable<byte>
, DEFINITELY prefer LINQ's Concat<> method. It's only slightly slower than the C# yield operator, but is more concise and more elegant.
IEnumerable<byte> rv = a1.Concat(a2).Concat(a3);
If you have an arbitrary number of arrays and are using .NET 3.5, you can make the System.Buffer.BlockCopy
solution more generic like this:
private byte[] Combine(params byte[][] arrays)
{
byte[] rv = new byte[arrays.Sum(a => a.Length)];
int offset = 0;
foreach (byte[] array in arrays) {
System.Buffer.BlockCopy(array, 0, rv, offset, array.Length);
offset += array.Length;
}
return rv;
}
*Note: The above block requires you adding the following namespace at the the top for it to work.
using System.Linq;
To Jon Skeet's point regarding iteration of the subsequent data structures (byte array vs. IEnumerable<byte>), I re-ran the last timing test (1 million elements, 4000 iterations), adding a loop that iterates over the full array with each pass:
System.Array.Copy
- 78.20550510 secondsSystem.Buffer.BlockCopy
- 77.89261900 secondsThe point is, it is VERY important to understand the efficiency of both the creation and the usage of the resulting data structure. Simply focusing on the efficiency of the creation may overlook the inefficiency associated with the usage. Kudos, Jon.
So after having the same issue with not being able to adjust height in text box, Width adjustment is fine but height never adjusted with the above suggestions (at least for me), I was finally able to take make it happen. As mentioned above, the issue appeared to be centered around a default font size setting in my text box and the behavior of the text box auto sizing around it. The default font size was tiny. Hence why trying to force the height or even turn off autosizing failed to fix the issue for me.
Set the Font properties to the size of your liking and then height change will kick in around the FONT size, automatically. You can still manually set your text box width. Below is snippet I added that worked for me.
$textBox = New-Object System.Windows.Forms.TextBox
$textBox.Location = New-Object System.Drawing.Point(60,300)
$textBox.Size = New-Object System.Drawing.Size(600,80)
$textBox.Font = New-Object System.Drawing.Font("Times New Roman",18,[System.Drawing.FontStyle]::Regular)
$textBox.Form.Font = $textbox.Font
Please note the Height value in '$textBox.Size = New-Object System.Drawing.Size(600,80)' is being ignored and the FONT size is actually controlling the height of the text box by autosizing around that font size.
To receive the new commits
git fetch
Reset
You can reset the commit for a local branch using git reset
.
To change the commit of a local branch:
git reset origin/master --hard
Be careful though, as the documentation puts it:
Resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded.
If you want to actually keep whatever changes you've got locally - do a --soft
reset instead. Which will update the commit history for the branch, but not change any files in the working directory (and you can then commit them).
Rebase
You can replay your local commits on top of any other commit/branch using git rebase
:
git rebase -i origin/master
This will invoke rebase in interactive mode where you can choose how to apply each individual commit that isn't in the history you are rebasing on top of.
If the commits you removed (with git push -f
) have already been pulled into the local history, they will be listed as commits that will be reapplied - they would need to be deleted as part of the rebase or they will simply be re-included into the history for the branch - and reappear in the remote history on the next push.
Use the help git command --help
for more details and examples on any of the above (or other) commands.
Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945
Also, the Angular docs now have a cookbook example that uses a Subject.
Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.
Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.
nav.service.ts
import {EventEmitter} from 'angular2/core';
export class NavService {
navchange: EventEmitter<number> = new EventEmitter();
constructor() {}
emitNavChangeEvent(number) {
this.navchange.emit(number);
}
getNavChangeEmitter() {
return this.navchange;
}
}
components.ts
import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';
@Component({
selector: 'obs-comp',
template: `obs component, item: {{item}}`
})
export class ObservingComponent {
item: number = 0;
subscription: any;
constructor(private navService:NavService) {}
ngOnInit() {
this.subscription = this.navService.getNavChangeEmitter()
.subscribe(item => this.selectedNavItem(item));
}
selectedNavItem(item: number) {
this.item = item;
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
@Component({
selector: 'my-nav',
template:`
<div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
<div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
`,
})
export class Navigation {
item = 1;
constructor(private navService:NavService) {}
selectedNavItem(item: number) {
console.log('selected nav item ' + item);
this.navService.emitNavChangeEvent(item);
}
}

Actually, there are two ways to include images in email.
The first way ensures that the user will see the image, even if in some cases it’s only as an attachment to the message. This method is exactly what we call as “embedding images in email" in daily life.
Essentially, you’re attaching the image to the email. The plus side is that, in one way or another, the user is sure to get the image. While the downside is two fold. Firstly, spam filters look for large, embedded images and often give you a higher spam score for embedding images in email (Lots of spammers use images to avoid having the inappropriate content in their emails read by the spam filters.). Secondly, if you pay to send your email by weight or kilobyte, this increases the size of your message. If you’re not careful, it can even make your message too big for the parameters of the email provider.
The second way to include images (and the far more common way) is the same way that you put an image on a web page. Within the email, you provide a url that is the reference to the image’s location on your server, exactly the same way that you would on a web page. This has several benefits. Firstly, you won’t get caught for spamming or for your message “weighing” too much because of the image. Secondly, you can make changes to the images after the email has been sent if you find errors in them. On the flip side, your recipient will need to actively turn on image viewing in their email client to see your images.
Sorry guys, but selecting from all_tab_privs_recd where grantee = 'your user' will not give any output except public grants and current user grants if you run the select from a different (let us say, SYS) user. As documentation says,
ALL_TAB_PRIVS_RECD describes the following types of grants:
Object grants for which the current user is the grantee Object grants for which an enabled role or PUBLIC is the grantee
So, if you're a DBA and want to list all object grants for a particular (not SYS itself) user, you can't use that system view.
In this case, you must perform a more complex query. Here is one taken (traced) from TOAD to select all object grants for a particular user:

This will list all object grants (including column grants) for your (specified) user. If you don't want column level grants then delete all part of the select beginning with 'union' clause.
UPD: Studying the documentation I found another view that lists all grants in much simpler way:
select * from DBA_TAB_PRIVS where grantee = 'your user';
Bear in mind that there's no DBA_TAB_PRIVS_RECD view in Oracle.
Using functions with the ellipses is not very safe. If performance is not critical for log function consider using operator overloading as in boost::format. You could write something like this:
#include <sstream>
#include <boost/format.hpp>
#include <iostream>
using namespace std;
class formatted_log_t {
public:
formatted_log_t(const char* msg ) : fmt(msg) {}
~formatted_log_t() { cout << fmt << endl; }
template <typename T>
formatted_log_t& operator %(T value) {
fmt % value;
return *this;
}
protected:
boost::format fmt;
};
formatted_log_t log(const char* msg) { return formatted_log_t( msg ); }
// use
int main ()
{
log("hello %s in %d-th time") % "world" % 10000000;
return 0;
}
The following sample demonstrates possible errors with ellipses:
int x = SOME_VALUE;
double y = SOME_MORE_VALUE;
printf( "some var = %f, other one %f", y, x ); // no errors at compile time, but error at runtime. compiler do not know types you wanted
log( "some var = %f, other one %f" ) % y % x; // no errors. %f only for compatibility. you could write %1% instead.
From docs TWIG docs:
Unlike in PHP, it's not possible to break or continue in a loop.
But still:
You can however filter the sequence during iteration which allows you to skip items.
Example 1 (for huge lists you can filter posts using slice, slice(start, length)
):
{% for post in posts|slice(0,10) %}
<h2>{{ post.heading }}</h2>
{% endfor %}
Example 2:
{% for post in posts if post.id < 10 %}
<h2>{{ post.heading }}</h2>
{% endfor %}
You can even use own TWIG filters for more complexed conditions, like:
{% for post in posts|onlySuperPosts %}
<h2>{{ post.heading }}</h2>
{% endfor %}
This has found an accepted answered, but I recently came across the UIImage+animatedGIF UIImage extension. It provides the following category:
+[UIImage animatedImageWithAnimatedGIFURL:(NSURL *)url]
allowing you to simply:
#import "UIImage+animatedGIF.h"
UIImage* mygif = [UIImage animatedImageWithAnimatedGIFURL:[NSURL URLWithString:@"http://en.wikipedia.org/wiki/File:Rotating_earth_(large).gif"]];
Works like magic.
Those types are there so that you can create arrays of the primitives, and not the boxed types. Since String isn't a primitive in Java, you can just use Array<String>
in Kotlin as the equivalent of a Java String[]
.
You can try this one
img{
max-height:500px;
max-width:500px;
height:auto;
width:auto;
}
This keeps the aspect ratio of the image and prevents either the two dimensions exceed 500px

Sure. Assuming you have a string with the file's name called fname
, the following does the trick.
with open(fname, 'r') as fin:
print(fin.read())
Your interior <div>
elements should likely both be float:left
. Divs size to 100% the size of their container width automatically. Try using display:inline-block
instead of width:auto
on the container div. Or possibly float:left
the container and also apply overflow:auto
. Depends on what you're after exactly.
In Windows 10 I had to run the batch file as an administrator.
SQL Alchemy session objects have their own execute
method:
result = db.session.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5})
All your application queries should be going through a session object, whether they're raw SQL or not. This ensures that the queries are properly managed by a transaction, which allows multiple queries in the same request to be committed or rolled back as a single unit. Going outside the transaction using the engine or the connection puts you at much greater risk of subtle, possibly hard to detect bugs that can leave you with corrupted data. Each request should be associated with only one transaction, and using db.session
will ensure this is the case for your application.
Also take note that execute
is designed for parameterized queries. Use parameters, like :val
in the example, for any inputs to the query to protect yourself from SQL injection attacks. You can provide the value for these parameters by passing a dict
as the second argument, where each key is the name of the parameter as it appears in the query. The exact syntax of the parameter itself may be different depending on your database, but all of the major relational databases support them in some form.
Assuming it's a SELECT
query, this will return an iterable of RowProxy
objects.
You can access individual columns with a variety of techniques:
for r in result:
print(r[0]) # Access by positional index
print(r['my_column']) # Access by column name as a string
r_dict = dict(r.items()) # convert to dict keyed by column names
Personally, I prefer to convert the results into namedtuple
s:
from collections import namedtuple
Record = namedtuple('Record', result.keys())
records = [Record(*r) for r in result.fetchall()]
for r in records:
print(r.my_column)
print(r)
If you're not using the Flask-SQLAlchemy extension, you can still easily use a session:
import sqlalchemy
from sqlalchemy.orm import sessionmaker, scoped_session
engine = sqlalchemy.create_engine('my connection string')
Session = scoped_session(sessionmaker(bind=engine))
s = Session()
result = s.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5})

Here is a sample that will help in applying button style consistently across your app.
Here is a sample Theme I used with the specific styles..
<style name="MyTheme" parent="@style/Theme.AppCompat.Light">
<item name="colorPrimary">@color/primary</item>
<item name="colorPrimaryDark">@color/primary_dark</item>
<item name="colorAccent">@color/accent</item>
<item name="android:buttonStyle">@style/ButtonAppTheme</item>
</style>
<style name="ButtonAppTheme" parent="android:Widget.Material.Button">
<item name="android:background">@drawable/material_button</item>
</style>
This is how I defined the button shape & effects inside res/drawable-v21 folder...
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp" />
<solid android:color="@color/primary" />
</shape>
</item>
</ripple>
2dp corners are to keep it consistent with Material theme.
$result->num_rows; only returns the number of row(s) affected by a query. When you are performing a count(*) on a table it only returns one row so you can not have an other result than 1.

The org.apache.http classes and the AndroidHttpClient class have been deprecated in Android 5.1. These classes are no longer being maintained and you should migrate any app code using these APIs to the URLConnection classes as soon as possible.
https://developer.android.com/about/versions/android-5.1.html#http
Thought of sharing my code using HttpUrlConnection
public String performPostCall(String requestURL,
HashMap<String, String> postDataParams) {
URL url;
String response = "";
try {
url = new URL(requestURL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("GET");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(postDataParams));
writer.flush();
writer.close();
os.close();
int responseCode=conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
String line;
BufferedReader br=new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line=br.readLine()) != null) {
response+=line;
}
}
else {
response="";
}
} catch (Exception e) {
e.printStackTrace();

result.append("&");
result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
result.append("=");

UPDATE 24/08/2016
Use some best library , such as :
because :
On lower API levels (mostly on Gingerbread and Froyo), HttpUrlConnection and HttpClient are far from being perfect
Since the introduction of Honeycomb (API 11), it's been mandatory to perform network operations on a separate thread, different from the main thread
If you are using bootstrap then use this class in the holding div
radio-inline
Example:
<label for="active" class="col-md-4 control-label">Active</label>
<div class="col-md-6 radio-inline">
<input type="checkbox" name="active" value="1">
<div>
Here the label Active and the checkbox will appear to be aligned.
The simplest answer is:
On whichever method you declare @Transactional
the boundary of transaction starts and boundary ends when method completes.
If you are using JPA call then all commits are with in this transaction boundary.
Lets say you are saving entity1, entity2 and entity3. Now while saving entity3 an exception occur, then as enitiy1 and entity2 comes in same transaction so entity1 and entity2 will be rollback with entity3.
Transaction :
- entity1.save
- entity2.save
- entity3.save
Any exception will result in rollback of all JPA transactions with DB.Internally JPA transaction are used by Spring.
Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing
#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')

Use:
drop table uno
drop table dos
create table uno
(
uid int,
col1 char(1),
col2 char(2)
)
create table dos
(
did int,
col1 char(1),
col2 char(2),
[sql] char(4)
)
insert into uno(uid) values (1)
insert into uno(uid) values (2)
insert into dos values (1,'a','b',null)
insert into dos values (2,'c','d','cool')
select * from uno
select * from dos
EITHER:
update uno set col1 = (select col1 from dos where uid = did and [sql]='cool'),
col2 = (select col2 from dos where uid = did and [sql]='cool')
OR:
update uno set col1=d.col1,col2=d.col2 from uno
inner join dos d on uid=did where [sql]='cool'
select * from uno
select * from dos
If the ID column name is the same in both tables then just put the table name before the table to be updated and use an alias for the selected table, i.e.:
update uno set col1 = (select col1 from dos d where uno.[id] = d.[id] and [sql]='cool'),
col2 = (select col2 from dos d where uno.[id] = d.[id] and [sql]='cool')
As an addition to fuzzyman's reply:
pip won't install binary packages and isn't well tested on Windows.
As Windows doesn't come with a compiler by default pip often can't be used there. easy_install can install binary packages for Windows.
Here is a trick on Windows:
you can use easy_install <package>
to install binary packages to avoid building a binary
you can use pip uninstall <package>
even if you used easy_install.
This is just a work-around that works for me on windows. Actually I always use pip if no binaries are involved.
See the current pip doku: http://www.pip-installer.org/en/latest/other-tools.html#pip-compared-to-easy-install
I will ask on the mailing list what is planned for that.
Here is the latest update:
The new supported way to install binaries is going to be wheel
!
It is not yet in the standard, but almost. Current version is still an alpha: 1.0.0a1
https://pypi.python.org/pypi/wheel
http://wheel.readthedocs.org/en/latest/
I will test wheel
by creating an OS X installer for PySide
using wheel
instead of eggs. Will get back and report about this.
cheers - Chris
The transition to wheel
is almost over. Most packages are supporting wheel
.
I promised to build wheels for PySide
, and I did that last summer. Works great!
HINT:
A few developers failed so far to support the wheel format, simply because they forget to
replace distutils
by setuptools
.
Often, it is easy to convert such packages by replacing this single word in setup.py
.
In the case of winforms:
If you include the images to your resources you can do it like this, very simple and straight forward:
public Form1()
{
InitializeComponent();
button1.MouseEnter += new EventHandler(button1_MouseEnter);
button1.MouseLeave += new EventHandler(button1_MouseLeave);
}
void button1_MouseLeave(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img1));
}
void button1_MouseEnter(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
I would not recommend hardcoding image paths.
As you have altered your question ...
There is no (on)MouseOver in winforms afaik, there are MouseHover and MouseMove events, but if you change image on those, it will not change back, so the MouseEnter + MouseLeave are what you are looking for I think. Anyway, changing the image on Hover or Move :
in the constructor:
button1.MouseHover += new EventHandler(button1_MouseHover);
button1.MouseMove += new MouseEventHandler(button1_MouseMove);
void button1_MouseMove(object sender, MouseEventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
void button1_MouseHover(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
To add images to your resources: Projectproperties/resources/add/existing file
There are multiple ways of applying aggregate functions to multiple columns.
GroupedData
class provides a number of methods for the most common functions, including count
, max
, min
, mean
and sum
, which can be used directly as follows:
Python:
df = sqlContext.createDataFrame(
[(1.0, 0.3, 1.0), (1.0, 0.5, 0.0), (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2)],
("col1", "col2", "col3"))
df.groupBy("col1").sum()
## +----+---------+-----------------+---------+
## |col1|sum(col1)| sum(col2)|sum(col3)|
## +----+---------+-----------------+---------+
## | 1.0| 2.0| 0.8| 1.0|
## |-1.0| -2.0|6.199999999999999| 0.7|
## +----+---------+-----------------+---------+
Scala
val df = sc.parallelize(Seq(
(1.0, 0.3, 1.0), (1.0, 0.5, 0.0),
(-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2))
).toDF("col1", "col2", "col3")
df.groupBy($"col1").min().show
// +----+---------+---------+---------+
// |col1|min(col1)|min(col2)|min(col3)|
// +----+---------+---------+---------+
// | 1.0| 1.0| 0.3| 0.0|
// |-1.0| -1.0| 0.6| 0.2|
// +----+---------+---------+---------+
Optionally you can pass a list of columns which should be aggregated
df.groupBy("col1").sum("col2", "col3")
You can also pass dictionary / map with columns a the keys and functions as the values:
Python
exprs = {x: "sum" for x in df.columns}
df.groupBy("col1").agg(exprs).show()
## +----+---------+
## |col1|avg(col3)|
## +----+---------+
## | 1.0| 0.5|
## |-1.0| 0.35|
## +----+---------+
Scala
val exprs = df.columns.map((_ -> "mean")).toMap
df.groupBy($"col1").agg(exprs).show()
// +----+---------+------------------+---------+
// |col1|avg(col1)| avg(col2)|avg(col3)|
// +----+---------+------------------+---------+
// | 1.0| 1.0| 0.4| 0.5|
// |-1.0| -1.0|3.0999999999999996| 0.35|
// +----+---------+------------------+---------+
Finally you can use varargs:
Python
from pyspark.sql.functions import min
exprs = [min(x) for x in df.columns]
df.groupBy("col1").agg(*exprs).show()
Scala
import org.apache.spark.sql.functions.sum
val exprs = df.columns.map(sum(_))
df.groupBy($"col1").agg(exprs.head, exprs.tail: _*)
There are some other way to achieve a similar effect but these should more than enough most of the time.

Another option:
UPDATE `table` SET the_col = current_timestamp
Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now()
.
i didn't find who made elegant answer , that's why let me say :
Array.from(
document.querySelectorAll('#txt1,#txt2')
).map(e => parseInt(e.value) || 0) // to avoid NaN
.reduce((a, b) => a+b, 0)
window.sum= () => _x000D_
document.getElementById('result').innerHTML= _x000D_
Array.from(_x000D_
document.querySelectorAll('#txt1,#txt2')_x000D_
).map(e=>parseInt(e.value)||0)_x000D_
.reduce((a,b)=>a+b,0)
_x000D_
<input type="text" id="txt1" onkeyup="sum()"/>_x000D_
<input type="text" id="txt2" onkeyup="sum()" style="margin-right:10px;"/><span id="result"></span>
_x000D_
If someone is looking for another option for Git Lab and the options above do not work, then we have another option. For a local installation of Git Lab server, we have found that the approach, below, allows us to include the package dependency. We generated and use an access token to do so.
$ npm install --save-dev https://git.yourdomain.com/userOrGroup/gitLabProjectName/repository/archive.tar.gz?private_token=InsertYourAccessTokenHere
Of course, if one is using an access key this way, it should have a limited set of permissions.
Good luck!
JAR File Manifest Attributes for Security
The JAR file manifest contains information about the contents of the JAR file, including security and configuration information.
Add the attributes to the manifest before the JAR file is signed.
See Modifying a Manifest File in the Java Tutorial for information on adding attributes to the JAR manifest file.
Permissions Attribute
The Permissions attribute is used to verify that the permissions level requested by the RIA when it runs matches the permissions level that was set when the JAR file was created.
Use this attribute to help prevent someone from re-deploying an application that is signed with your certificate and running it at a different privilege level. Set this attribute to one of the following values:
sandbox - runs in the security sandbox and does not require additional permissions.
all-permissions - requires access to the user's system resources.

There's a niche case where git mv
remains very useful: when you want to change the casing of a file name on a case-insensitive file system. Both APFS (mac) and NTFS (windows) are, by default, case-insensitive (but case-preserving).
greg.kindel mentions this in a comment on CB Bailey's answer.
Suppose you are working on a mac and have a file Mytest.txt
managed by git. You want to change the file name to MyTest.txt
.
You could try:
$ mv Mytest.txt MyTest.txt
overwrite MyTest.txt? (y/n [n]) y
$ git status
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
Oh dear. Git doesn't acknowledge there's been any change to the file.
You could work around this with by renaming the file completely then renaming it back:
$ mv Mytest.txt temp.txt
$ git rm Mytest.txt
rm 'Mytest.txt'
$ mv temp.txt MyTest.txt
$ git add MyTest.txt
$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
renamed: Mytest.txt -> MyTest.txt
Hurray!
Or you could save yourself all that bother by using git mv
:
$ git mv Mytest.txt MyTest.txt
$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
renamed: Mytest.txt -> MyTest.txt
That would be the Enter key.
I was facing the same problem. For my solution, I added br
enclosed between 2 brackets < > enclosed in double quotation marks, and preceded and followed by the + sign:
+"<br>"+
Try this in your browser and see, it certainly works in my Internet Explorer.
#include<stdio.h>
main()
{
int i,j,k;
for(i=2;i<=100;i++)
{
k=0;
for(j=2;j<=i;j++)
{
if(i%j==0)
k++;
}
if(k==1)
printf("%d\t",i);
}
}
All the considerations made by @EdChum in 2014 are still valid, but the pandas.Dataframe.ix
method is deprecated from the version 0.0.20 of pandas. Directly from the docs:
Warning: Starting in 0.20.0, the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.
In subsequent versions of pandas, this method has been replaced by new indexing methods pandas.Dataframe.loc and pandas.Dataframe.iloc.
If you want to learn more, in this post you can find comparisons between the methods mentioned above.
Ultimately, to date (and there does not seem to be any change in the upcoming versions of pandas from this point of view), the answer to this question is as follows:
foo = df.loc[(df['column1']==value) | (df['columns2'] == 'b') | (df['column3'] == 'c')]
I had this issue too, after following this guide, it was simply 1 additional patch that was required to get past the
Rule "Prior Visual Studio 2010 instances requiring update." failed.
Was to locate this file, and patch my machine
VS10sp1-KB983509.msp
Simply do a file search on the installation media for SQL Server 2012, in my case it was in \redist\VisualStudioShell (whereas in the guide it's listed as being in a different location).
Then hit 're-run'.
Add ?var1=data1&var2=data2
to the end of url to submit values to the page via GET:
using System.Net;
using System.IO;
string url = "https://www.example.com/scriptname.php?var1=hello";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();
There is an easier way where you don't have to type any code (Ideal for Testing or One-time updates):
Step 1
Step 2
Step 3
Step 4
Step 5
Note - 1: If the columns are not in the correct order as in Target table, you can always follow Step 2, and Select the Columns in the same order as in the Target table
Note - 2 - If you have Identity columns then execute SET IDENTITY_INSERT sometableWithIdentity ON
and then follow above steps, and in the end execute SET IDENTITY_INSERT sometableWithIdentity OFF
"A virtual function or virtual method is a function or method whose behavior can be overridden within an inheriting class by a function with the same signature" - wikipedia
This is not a good explanation for virtual functions. Because, even if a member is not virtual, inheriting classes can override it. You can try and see it yourself.
The difference shows itself when a function take a base class as a parameter. When you give an inheriting class as the input, that function uses the base class implementation of the overriden function. However, if that function is virtual, it uses the one that is implemented in the deriving class.
"Note that you need to have image fully loaded first (otherwise ending up in having empty images), so in some cases you'd need to wrap handling into: bannerImage.addEventListener("load", function () {}); – yuga Nov 1 '17 at 13:04"
This is extremely IMPORTANT. One of the the options i'm exploring this afternoon is using javascript callback methods rather than addEventListeners since that doesn't seem to bind correctly either. Getting all the elements ready before page load WITHOUT a page refresh is critical.
If anyone can expand upon this please do - as in, did you use a settimeout, a wait, a callback, or an addEventListener method to get the desired result. Which one and why?
Another option for in a bash script:
mailbody="Testmail via bash script"
echo "From: [email protected]" > /tmp/mailtest
echo "To: [email protected]" >> /tmp/mailtest
echo "Subject: Mailtest subject" >> /tmp/mailtest
echo "" >> /tmp/mailtest
echo $mailbody >> /tmp/mailtest
cat /tmp/mailtest | /usr/sbin/sendmail -t
/tmp/mailtest
is overwritten everytime this script is used. I think you could do it using a specs file.
Under MinGW you could run
gcc -dumpspecs > specs
Where it says
*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT}
You change it to
*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT} -std=c++11
And then place it in
/mingw/lib/gcc/mingw32/<version>/specs
I'm sure you could do the same without a MinGW build. Not sure where to place the specs file though.
The folder is probably either /gcc/lib/ or /gcc/.
In VS code 'User Settings', you can edit visible colours using the following tags(this is a sample and there are much more tags),
"workbench.colorCustomizations": {
"list.inactiveSelectionBackground": "#C5DEF0",
"sideBar.background": "#F8F6F6",
"sideBar.foreground": "#000000",
"editor.background": "#FFFFFF",
"editor.foreground": "#000000",
"sideBarSectionHeader.background": "#CAC9C9",
"sideBarSectionHeader.foreground": "#000000",
"activityBar.border": "#FFFFFF",
"statusBar.background": "#102F97",
"scrollbarSlider.activeBackground": "#77D4CB",
"scrollbarSlider.hoverBackground": "#8CE6DA",
"badge.background": "#81CA91"}
If you want to edit some C++ color tokens, use the following tag,
"editor.tokenColorCustomizations": {
"numbers": "#2247EB",
"comments": "#6D929C",
"functions": "#0D7C28"
}
It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:
ObjectContext.DeleteObject(entity)
marks the entity as Deleted
in the context. (It's EntityState
is Deleted
after that.) If you call SaveChanges
afterwards EF sends a SQL DELETE
statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.
EntityCollection.Remove(childEntity)
marks the relationship between parent and childEntity
as Deleted
. If the childEntity
itself is deleted from the database and what exactly happens when you call SaveChanges
depends on the kind of relationship between the two:
If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL
values, this foreign will be set to null and if you call SaveChanges
this NULL
value for the childEntity
will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE
statement. No DELETE
statement occurs.
If the relationship is required (the FK doesn't allow NULL
values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject
then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges
- the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.
If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL
) EF will mark the childEntity
as Deleted
as well. If you call SaveChanges
a SQL DELETE
statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.
I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)
The simplest way to do this is to install Json.NET
from nuget and add the [JsonIgnore]
attribute to the virtual property in the class, for example:
public string Name { get; set; }
public string Description { get; set; }
public Nullable<int> Project_ID { get; set; }
[JsonIgnore]
public virtual Project Project { get; set; }
Although these days, I create a model with only the properties I want passed through so it's lighter, doesn't include unwanted collections, and I don't lose my changes when I rebuild the generated files...
its work for me SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); sdf.format(new Date));
All numbers in Lua are floats (edit: Lua 5.2 or less). If you truly want to convert to an "int" (or at least replicate this behavior), you can do this:
local function ToInteger(number)
return math.floor(tonumber(number) or error("Could not cast '" .. tostring(number) .. "' to number.'"))
end
In which case you explicitly convert the string (or really, whatever it is) into a number, and then truncate the number like an (int) cast would do in Java.
Edit: This still works in Lua 5.3, even thought Lua 5.3 has real integers, as math.floor()
returns an integer, whereas an operator such as number // 1
will still return a float if number
is a float.
SQL Loader is the way to go. I recently loaded my table from a csv file,new to this concept,would like to share an example.
LOAD DATA
infile '/ipoapplication/utl_file/LBR_HE_Mar16.csv'
REPLACE
INTO TABLE LOAN_BALANCE_MASTER_INT
fields terminated by ',' optionally enclosed by '"'
(
ACCOUNT_NO,
CUSTOMER_NAME,
LIMIT,
REGION
)
Place the control file and csv at the same location on the server. Locate the sqlldr exe and invoce it.
sqlldr userid/passwd@DBname control= Ex : sqlldr abc/xyz@ora control=load.ctl
Hope it helps.
Add column to your migration file and run this command.
php artisan migrate:refresh --path=/database/migrations/your_file_name.php
Does an implicit conversion occur between Task<> and int?
Nope. This is just part of how async
/await
works.
Any method declared as async
has to have a return type of:
void
(avoid if possible)Task
(no result beyond notification of completion/failure)Task<T>
(for a logical result of type T
in an async manner)The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length
- you can't make the method just return int
, as the actual method will return when it hits the first await
expression which hasn't already completed. So instead, it returns a Task<int>
which will complete when the async method itself completes.
Note that await
does the opposite - it unwraps a Task<T>
to a T
value, which is how this line works:
string urlContents = await getStringTask;
... but of course it unwraps it asynchronously, whereas just using Result
would block until the task had completed. (await
can unwrap other types which implement the awaitable pattern, but Task<T>
is the one you're likely to use most often.)
This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:
public async Task<int> AccessTheWebAndDoubleAsync()
{
var task = AccessTheWebAsync();
int result = await task;
return result * 2;
}
(Or simply return await AccessTheWebAsync() * 2;
of course.)
This worked for me (macOS v10.13 (High Sierra)):
sudo -u postgres /Library/PostgreSQL/9.6/bin/pg_ctl start -D /Library/PostgreSQL/9.6/data
Or first
cd /Library/PostgreSQL/9.6/bin/
Answer for this question is good if you want to overwrite your file everytime you rerun your program, but if you want your records to not be lost at rerunning your program, you may want to try this
public void writeAudit(String actionName) {
String whereWrite = "./csvFiles/audit.csv";
try {
FileWriter fw = new FileWriter(whereWrite, true);
BufferedWriter bw = new BufferedWriter(fw);
PrintWriter pw = new PrintWriter(bw);
Date date = new Date();
pw.println(actionName + "," + date.toString());
pw.flush();
pw.close();
} catch (FileNotFoundException e) {
System.out.println(e.getMessage());
} catch (IOException e) {
e.printStackTrace();
}
}
Good morning.
I was have the same problem with upload of multiple images. Solution was more simple than I had imagined: include [] in the name field.
<input type="file" name="files[]" multiple>
I did not make any modification on FormData.
There is also someone who managed to modify CR for VS.NET 2010 to install on 2012, using MS ORCA
in this thread: http://scn.sap.com/thread/3235515 . I couldn't get it to work myself, though.
If the variable holding the dataframe is called df, then:
len(df.columns)
gives the number of columns.
And for those who want the number of rows:
len(df.index)
For a tuple containing the number of both rows and columns:
df.shape
I have also come across this need for my database project. I decided to share my findings here.
1) There is no way to a NOT NULL field without a default when data already exists (Can I add a not null column without DEFAULT value)
2) This topic has been addressed for a long time. Here is a 2008 question (Add a column with a default value to an existing table in SQL Server)
3) The DEFAULT constraint is used to provide a default value for a column. The default value will be added to all new records IF no other value is specified. (https://www.w3schools.com/sql/sql_default.asp)
4) The Visual Studio Database Project that I use for development is really good about generating change scripts for you. This is the change script created for my DB promotion:
GO
PRINT N'Altering [dbo].[PROD_WHSE_ACTUAL]...';
GO
ALTER TABLE [dbo].[PROD_WHSE_ACTUAL]
ADD [DATE] DATE DEFAULT getdate() NOT NULL;
-
Here are the steps I took to update my database using Visual Studio for development.
1) Add default value (Visual Studio SSDT: DB Project: table designer)
2) Use the Schema Comparison tool to generate the change script.

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator
And another link here
AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).
Not sure if this matters to anyone else, but I prefer the id for the table to be the first column in the database. The syntax for that is:
ALTER TABLE your_db.your_table ADD COLUMN `id` int(10) UNSIGNED PRIMARY KEY AUTO_INCREMENT FIRST;
Which is just a slight improvement over the first answer. If you wanted it to be in a different position, then
ALTER TABLE unique_address ADD COLUMN `id` int(10) UNSIGNED PRIMARY KEY AUTO_INCREMENT AFTER some_other_column;

I had great trouble with this for devices that had vibration turned off in some manner, but we needed it to work regardless, because it is critical to our application functioning, and since it is just an integer to a documented method call, it will pass validation. So I have tried some sounds that were outside of the well documented ones here: TUNER88/iOSSystemSoundsLibrary
I have then stumbled upon 1352, which is working regardless of the silent switch or the settings on the device (Settings->vibrate on ring, vibrate on silent)
.
- (void)vibratePhone;
{
if([[UIDevice currentDevice].model isEqualToString:@"iPhone"])
{
AudioServicesPlaySystemSound (1352); //works ALWAYS as of this post
}
else
{
// Not an iPhone, so doesn't have vibrate
// play the less annoying tick noise or one of your own
AudioServicesPlayAlertSound (1105);
}
}

You can think of it as an anonymous function - here's some more info: Wikipedia - Anonymous Function
From my looking you give a null value to a textbox and return in a ToString()
as it is a static method. You can replace it with Convert.ToString()
that can enable null value.
You may want to try
var d = new Date();
d.toLocaleString(); // -> "2/1/2013 7:37:08 AM"
d.toLocaleDateString(); // -> "2/1/2013"
d.toLocaleTimeString(); // -> "7:38:05 AM"
This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.
<LimitExcept OPTIONS>
AuthType Basic
AuthName <AUTH_NAME>
Require valid-user
AuthUserFile <FILE_PATH>
</LimitExcept>
you can always use new stdClass()
. Example code:
$object = new stdClass();
$object->property = 'Here we go';
var_dump($object);
/*
outputs:
object(stdClass)#2 (1) {
["property"]=>
string(10) "Here we go"
}
*/
Also as of PHP 5.4 you can get same output with:
$object = (object) ['property' => 'Here we go'];
var textArea = document.getElementById('myTextAreaId');
var lines = textArea.value.split('\n'); // lines is an array of strings
// Loop through all lines
for (var j = 0; j < lines.length; j++) {
console.log('Line ' + j + ' is ' + lines[j])
}
var lines = $('#myTextAreaId').val().split('\n'); // lines is an array of strings
// Loop through all lines
for (var j = 0; j < lines.length; j++) {
console.log('Line ' + j + ' is ' + lines[j])
}
Side note, if you prefer forEach a sample loop is
lines.forEach(function(line) {
console.log('Line is ' + line)
})
Simply like that :
<a id="myLink" onclick="alert('link click');">LINK 1</a>
<a id="myLink2" onclick="document.getElementById('myLink').click()">Click link 1</a>
or at page load :
<body onload="document.getElementById('myLink').click()">
...
<a id="myLink" onclick="alert('link click');">LINK 1</a>
...
</body>
I figured out a method that works ~35% faster than your 6bits+Carmack+sqrt code, at least with my CPU (x86) and programming language (C/C++). Your results may vary, especially because I don't know how the Java factor will play out.
My approach is threefold:
int64 x
.)
if( x < 0 || (x&2) || ((x & 7) == 5) || ((x & 11) == 8) )
return false;
if( x == 0 )
return true;
int64 y = x;
y = (y & 4294967295LL) + (y >> 32);
y = (y & 65535) + (y >> 16);
y = (y & 255) + ((y >> 8) & 255) + (y >> 16);
// At this point, y is between 0 and 511. More code can reduce it farther.
To actually check if the residue is a square, I look up the answer in a precomputed table.
if( bad255[y] )
return false;
// However, I just use a table of size 512
if((x & 4294967295LL) == 0)
x >>= 32;
if((x & 65535) == 0)
x >>= 16;
if((x & 255) == 0)
x >>= 8;
if((x & 15) == 0)
x >>= 4;
if((x & 3) == 0)
x >>= 2;
At this point, for our number to be a square, it must be 1 mod 8.
if((x & 7) != 1)
return false;
The basic structure of Hensel's lemma is the following. (Note: untested code; if it doesn't work, try t=2 or 8.)
int64 t = 4, r = 1;
t <<= 1; r += ((x - r * r) & t) >> 1;
t <<= 1; r += ((x - r * r) & t) >> 1;
t <<= 1; r += ((x - r * r) & t) >> 1;
// Repeat until t is 2^33 or so. Use a loop if you want.
The idea is that at each iteration, you add one bit onto r, the "current" square root of x; each square root is accurate modulo a larger and larger power of 2, namely t/2. At the end, r and t/2-r will be square roots of x modulo t/2. (Note that if r is a square root of x, then so is -r. This is true even modulo numbers, but beware, modulo some numbers, things can have even more than 2 square roots; notably, this includes powers of 2.) Because our actual square root is less than 2^32, at that point we can actually just check if r or t/2-r are real square roots. In my actual code, I use the following modified loop:
int64 r, t, z;
r = start[(x >> 3) & 1023];
do {
z = x - r * r;
if( z == 0 )
return true;
if( z < 0 )
return false;
t = z & (-z);
r += (z & t) >> 1;
if( r > (t >> 1) )
r = t - r;
} while( t <= (1LL << 33) );
The speedup here is obtained in three ways: precomputed start value (equivalent to ~10 iterations of the loop), earlier exit of the loop, and skipping some t values. For the last part, I look at z = r - x * x
, and set t to be the largest power of 2 dividing z with a bit trick. This allows me to skip t values that wouldn't have affected the value of r anyway. The precomputed start value in my case picks out the "smallest positive" square root modulo 8192.
Even if this code doesn't work faster for you, I hope you enjoy some of the ideas it contains. Complete, tested code follows, including the precomputed tables.
typedef signed long long int int64;
int start[1024] =

There is jq

jq '.Body'
Visit this for jq: https://stedolan.github.io/jq/
ID % 2
reduces all integer (monetary and numeric are allowed, too) numbers to 0 and 1 effectively.
Read about the modulo operator in the manual.
Try this, It always works, and you will get NO TypeError:

var i2 = document.getElementById('i2');
var __i = {'user' : document.getElementsByName("username")[0], 'pass' : document.getElementsByName("password")[0] };
if( __i.user.value.length >= 1 ) { i1.value = ''; } else { i1.value = 'Acc'; }
if( __i.pass.value.length >= 1 ) { i2.value = ''; } else { i2.value = 'Pwd'; }
}catch(e){

}
You can use string.Split
and string.Join
:
string theString = "Some Very Large String Here";
var array = theString.Split(' ');
string firstElem = array.First();
string restOfArray = string.Join(" ", array.Skip(1));
If you know you always only want to split off the first element, you can use:
var array = theString.Split(' ', 2);
This makes it so you don't have to join:
string restOfArray = array[1];

If you have to use Relational DataBase to organize tree data structure then Postgresql has cool ltree module that provides data type for representing labels of data stored in a hierarchical tree-like structure. You can get the idea from there.(For more information see: http://www.postgresql.org/docs/9.0/static/ltree.html)
In common LDAP is used to organize records in hierarchical structure.
I found I could improve the situation a little with CSS dedicated to Webkit (Safari, Chrome). However, I had to set a fixed width and height on the field because the font change will resize the field.
@media screen and (-webkit-min-device-pixel-ratio:0){ /* START WEBKIT */
INPUT[type="password"]{
font-family:Verdana,sans-serif;
height:28px;
font-size:19px;
width:223px;
padding:5px;
}
} /* END WEBKIT */
As I understand the problem is that request is sent from localhost:3000 to localhost:8080 and browser rejects such requests as CORS. So solution was to create proxy
My solution was :
import proxy from 'http-proxy-middleware'
app.use('/api/**', proxy({ target: "http://localhost:8080" }));
Put 0 as default in SQL or add 0 into your area of table
Important thing to be noticed:
Difference between Replace and Replace with backstack is whenever we use only replace then the fragment is destroyed ( ondestroy() is called ) and when we use replace with backstack then fragments onDestroy() is not called ( i.e when back button is pressed fragment is invoked with its onCreateView())
This works for me pretty fine,
git checkout origin/branchname
if you're already in branch then it's better to do pull or rebase
git pull
or
git -c core.quotepath=false fetch origin --progress --prune
Later you can simply use
git commit --amend -m "Your message here"
or if you like to open text-editor then use
git commit --amend
I will prefer using text-editor if you have many comments. You can set your preferred text-editor with command
git config --global core.editor your_preffered_editor_here
Anyway, when your are done changing the commit message, save it and exit
and then run
git push --force
And you're done
A variation on your idea is to have a server-side USER-AGENT detector
that will figure out what style sheet to attach to the page. This way you can have a firefox.css, ie.css, opera.css, etc
.
You can accomplish a similar thing in Javascript itself, although you may not regard it as clean.
I have done a similar thing by having a default.css
which includes all common styles and then specific style sheets
are added to override, or enhance the defaults.
The proper URL scheme is tel:[number] so you would do
<a href="tel:5551234567"><img src="callme.jpg" /></a>

there is a alternative to margin-left:auto; margin-right: auto;
or margin:0 auto;
for the ones that use position:absolute;
this is how:
you set the left position of the element to 50% (left:50%;
) but that will not center it correctly in order for the element to be centered correctly you need to give it a margin of minus half of it`s width, that will center your element perfectly
here is an example: http://jsfiddle.net/35ERq/3/
This means a class is redundantly mentioned with a class function. Try removing JSONDeserializer::
Use:
window.location = "http://my.url.here";
Here's some quick-n-dirty code that uses jQuery to do what you want. I highly recommend using jQuery. It'll make things a lot more easier for you, especially since you're new to JavaScript.
<select id = "pricingOptions" name = "pricingOptions">
<option value = "500">Option A</option>
<option value = "1000">Option B</option>
</select>
<script type = "text/javascript" language = "javascript">
jQuery(document).ready(function() {
jQuery("#pricingOptions").change(function() {
if(this.options[this.selectedIndex].value == "500") {
window.location = "http://example.com/foo.php?option=500";
}
});
});
</script>
For Travers an String you can also use charAt()
with the string.
like :
String str = "xyz"; // given String
char st = str.charAt(0); // for example we take 0 index element
System.out.println(st); // print the char at 0 index
charAt()
is method of string handling in java which help to Travers the string for specific character.
Python does not have unary increment/decrement operators (--
/++
). Instead, to increment a value, use
a += 1
But be careful here. If you're coming from C, even this is different in python. Python doesn't have "variables" in the sense that C does, instead python uses names and objects, and in python int
s are immutable.
so lets say you do
a = 1
What this means in python is: create an object of type int
having value 1
and bind the name a
to it. The object is an instance of int
having value 1
, and the name a
refers to it. The name a
and the object to which it refers are distinct.
Now lets say you do
a += 1
Since int
s are immutable, what happens here is as follows:
a
refers to (it is an int
with id 0x559239eeb380
)0x559239eeb380
(it is 1
)int
object with value 2
(it has object id 0x559239eeb3a0
)a
to this new objecta
refers to object 0x559239eeb3a0
and the original object (0x559239eeb380
) is no longer refered to by the name a
. If there aren't any other names refering to the original object it will be garbage collected later.Give it a try yourself:
a = 1
print(hex(id(a)))
a += 1
print(hex(id(a)))
Using Array.prototype.map()
const zip = (a, b) => a.map((k, i) => [k, b[i]]);
console.log(zip([1,2,3], ["a","b","c"]));
// [[1, "a"], [2, "b"], [3, "c"]]
_x000D_
Using Array.from()
const zip = (a, b) => Array.from(Array(Math.max(b.length, a.length)), (_, i) => [a[i], b[i]]);
console.log( zip([1,2,3], ["a","b","c","d"]) );
// [[1, "a"], [2, "b"], [3, "c"], [undefined, "d"]]
_x000D_
Using Array.prototype.fill() and Array.prototype.map()
const zip = (a, b) => Array(Math.max(b.length, a.length)).fill().map((_,i) => [a[i], b[i]]);
console.log(zip([1,2,3], ["a","b","c","d"]));
// [[1, "a"], [2, "b"], [3, "c"], [undefined, 'd']]
_x000D_
I just added this code to my service class so I could indirectly call OnStart, similar for OnStop.
public void MyOnStart(string[] args)
{
OnStart(args);
}
What about the ansicolors library? You can simple do:
from colors import color, red, blue
# common colors
print(red('This is red'))
print(blue('This is blue'))
# colors by name or code
print(color('Print colors by name or code', 'white', '#8a2be2'))
You don't need both hibernate.cfg.xml
and persistence.xml
in this case. Have you tried removing hibernate.cfg.xml
and mapping everything in persistence.xml
only?
But as the other answer also pointed out, this is not okay like this:
@Id
@JoinColumn(name = "categoria")
private String id;
Didn't you want to use @Column
instead?
Use border-collapse and border-spacing to get spaces between the table cells. I would not recommend using floating cells as suggested by QQping.
Tenary Operator helps keep it short and simple.
echo (isset($_SERVER['HTTPS']) ? 'http' : 'https' ). "://" . $_SERVER['SERVER_NAME'] ;
Be careful if you have to deal with large numbers.
int[] arr = new int[]{Integer.MIN_VALUE, Integer.MIN_VALUE};
long sum = Arrays.stream(arr).sum(); // Wrong: sum == 0
The sum above is not 2 * Integer.MIN_VALUE
.
You need to do this in this case.
long sum = Arrays.stream(arr).mapToLong(Long::valueOf).sum(); // Correct
Your logic is correct but you have 2 mistakes apparently everyone missed:
just change if(Number(i) = 'NaN')
to if(Number(i) == NaN)
NaN
is a constant and you should use double equality signs to compare, a single one is used to assign values to variables.
In cryptography there are two types of algorithms used:
Symmetric algorithms
A single key is used to encrypt data. When encrypted with the key, the data can be decrypted using the same key. If, for example, Mary encrypts a message using the key "my-secret" and sends it to John, he will be able to decrypt the message correctly with the same key "my-secret".
Asymmetric algorithms
Two keys are used to encrypt and decrypt messages. While one key(public) is used to encrypt the message, the other key(private) can only be used to decrypt it. So, John can generate both public and private keys, then send only the public key to Mary to encrypt her message. The message can only be decrypted using the private key.
HS256 and RS256 Scenario
These algorithms are NOT used to encrypt/decryt data. Rather they are used to verify the origin or the authenticity of the data. When Mary needs to send an open message to Jhon and he needs to verify that the message is surely from Mary, HS256 or RS256 can be used.
HS256 can create a signature for a given sample of data using a single key. When the message is transmitted along with the signature, the receiving party can use the same key to verify that the signature matches the message.
RS256 uses pair of keys to do the same. A signature can only be generated using the private key. And the public key has to be used to verify the signature. In this scenario, even if Jack finds the public key, he cannot create a spoof message with a signature to impersonate Mary.
You can also do Dictionary:
var list = new List<string> { "a", "b", "a", "c", "a", "b" };
var result = list.GroupBy(x => x)
.ToDictionary(y=>y.Key, y=>y.Count())
.OrderByDescending(z => z.Value);
foreach (var x in result)
{
Console.WriteLine("Value: " + x.Key + " Count: " + x.Value);
}
Also you can add #include<vector>
in the header. When two of the above solutions don't work.
You may want to use:
SELECT Name, 'Unpaid' AS Status FROM table;
The SELECT
clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:
SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ]
<select_list>
Where the expression
can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.
No external libraries needed.
Returns a Collection so you can do whatever you want with it after the call.
public static Collection<File> listFileTree(File dir) {
Set<File> fileTree = new HashSet<File>();
if(dir==null||dir.listFiles()==null){
return fileTree;
}
for (File entry : dir.listFiles()) {
if (entry.isFile()) fileTree.add(entry);
else fileTree.addAll(listFileTree(entry));
}
return fileTree;
}
Yes, there seems some restrictions by some browser in SVG. The developertool restrict it to 8000px; The following dynamically generated Chart fails for example in Chrome.

You can use your favourite telnet (not recommended) or ssh (recommended) application to connect to your Synology box and use it as a terminal.

I asked a similar question. Based on @sawa's answer, the most succinct way to represent an integer in a string in binary format is to use the string formatter:
"%b" % 245
=> "11110101"
You can also choose how long the string representation to be, which might be useful if you want to compare fixed-width binary numbers:
1.upto(10).each { |n| puts "%04b" % n }
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010
As written, there's nothing wrong with your code. Are you sure you haven't done something like
int strategy;
...
enum {RANDOM, IMMEDIATE, SEARCH} strategy;
What lines do the error messages point to? When it says "previous declaration of 'strategy' was here", what's "here" and what does it show?
From MSDN
string value = "9quali52ty3";
// Convert the string into a byte[].
byte[] asciiBytes = Encoding.ASCII.GetBytes(value);
You now have an array of the ASCII value of the bytes. I got the following:
57 113 117 97 108 105 53 50 116 121 51
There are a couple of other applications that i've seen recommended, you'll find them here:
If you are using ng-pattern and material this does the job.
vm.validateEmail = '([a-zA-Z0-9_.]{1,})((@[a-zA-Z]{2,})[\\\.]([a-zA-Z]{2}|[a-zA-Z]{3}))';
UPDATE: Small one-liner function using the ES2017 String.prototype.padStart
method:
const zeroPad = (num, places) => String(num).padStart(places, '0')_x000D_
_x000D_
console.log(zeroPad(5, 2)); // "05"_x000D_
console.log(zeroPad(5, 4)); // "0005"_x000D_
console.log(zeroPad(5, 6)); // "000005"_x000D_
console.log(zeroPad(1234, 2)); // "1234"
_x000D_
Another ES5 approach:
function zeroPad(num, places) {
var zero = places - num.toString().length + 1;
return Array(+(zero > 0 && zero)).join("0") + num;
}
zeroPad(5, 2); // "05"
zeroPad(5, 4); // "0005"
zeroPad(5, 6); // "000005"
zeroPad(1234, 2); // "1234" :)
You can also use
<input type="button" value = "Refresh" onclick="history.go(0)" />
It works fine for me.
I know it is a bit picky, but all the answers so far are not quite right.
The point of path.join() is to eliminate the need for the caller to know which directory separator to use (making code platform agnostic).
Technically the correct answer would be something like:
var path = require("path");
fs.readFile(path.join(__dirname, '..', '..', 'foo.bar'));
I would have added this as a comment to Alex Wayne's answer but not enough rep yet!
EDIT: as per user1767586's observation
There are many ways to exit after insert
When you insert data into a table, you can use the OUTPUT clause to return a copy of the data that’s been inserted into the table. The OUTPUT clause takes two basic forms: OUTPUT and OUTPUT INTO. Use the OUTPUT form if you want to return the data to the calling application. Use the OUTPUT INTO form if you want to return the data to a table or a table variable.
DECLARE @MyTableVar TABLE (id INT,NAME NVARCHAR(50));
INSERT INTO tableName
(
NAME,....
)OUTPUT INSERTED.id,INSERTED.Name INTO @MyTableVar
VALUES
(
'test',...
)
IDENT_CURRENT: It returns the last identity created for a particular table or view in any session.
SELECT IDENT_CURRENT('tableName') AS [IDENT_CURRENT]
SCOPE_IDENTITY: It returns the last identity from a same session and the same scope. A scope is a stored procedure/trigger etc.
SELECT SCOPE_IDENTITY() AS [SCOPE_IDENTITY];
@@IDENTITY: It returns the last identity from the same session.
SELECT @@IDENTITY AS [@@IDENTITY];
Instead of .*
use .\{-}
.
%s/style=".\{-}"//g
Also, see :help non-greedy
Here's one approach which automates creating labels above each column of a listbox (on a worksheet).
It will work (though not super-pretty!) as long as there's no horizontal scrollbar on your listbox.
Sub Tester()
Dim i As Long
With Me.lbTest
.Clear
.ColumnCount = 5
'must do this next step!
.ColumnWidths = "70;60;100;60;60"
.ListStyle = fmListStylePlain
Debug.Print .ColumnWidths
For i = 0 To 10
.AddItem
.List(i, 0) = "blah" & i
.List(i, 1) = "blah"
.List(i, 2) = "blah"
.List(i, 3) = "blah"
.List(i, 4) = "blah"
Next i
End With
LabelHeaders Me.lbTest, Array("Header1", "Header2", _
"Header3", "Header4", "Header5")
End Sub
Sub LabelHeaders(lb, arrHeaders)
Const LBL_HT As Long = 15
Dim T, L, shp As Shape, cw As String, arr
Dim i As Long, w
'delete any previous headers for this listbox
For i = lb.Parent.Shapes.Count To 1 Step -1
If lb.Parent.Shapes(i).Name Like lb.Name & "_*" Then
lb.Parent.Shapes(i).Delete
End If
Next i
'get an array of column widths
cw = lb.ColumnWidths
If Len(cw) = 0 Then Exit Sub
cw = Replace(cw, " pt", "")
arr = Split(cw, ";")
'start points for labels
T = lb.Top - LBL_HT
L = lb.Left
For i = LBound(arr) To UBound(arr)
w = CLng(arr(i))
If i = UBound(arr) And (L + w) < lb.Width Then w = lb.Width - L
Set shp = ActiveSheet.Shapes.AddShape(msoShapeRectangle, _
L, T, w, LBL_HT)
With shp
.Name = lb.Name & "_" & i
'do some formatting
.Line.ForeColor.RGB = vbBlack
.Line.Weight = 1
.Fill.ForeColor.RGB = RGB(220, 220, 220)
.TextFrame2.TextRange.Characters.Text = arrHeaders(i)
.TextFrame2.TextRange.Font.Size = 9
.TextFrame2.TextRange.Font.Fill.ForeColor.RGB = vbBlack
End With
L = L + w
Next i
End Sub
I hope you were joking about writing your own parser. :-)
For such a simple mapping, most tools from http://json.org (section java) would work. For one of them (Jackson https://github.com/FasterXML/jackson-databind/#5-minute-tutorial-streaming-parser-generator), you'd do:
Map<String,Object> result =
new ObjectMapper().readValue(JSON_SOURCE, HashMap.class);
(where JSON_SOURCE is a File, input stream, reader, or json content String)
A cause can be invalid encoding in the URL request. Such as % being passed un-encoded.
To add this to SQL Developer as an extension do the following:
<items>
<item type="editor" node="TableNode" vertical="true">
<title><![CDATA[FK References]]></title>
<query>
<sql>
<![CDATA[select a.owner,
a.table_name,
a.constraint_name,
a.status
from all_constraints a
where a.constraint_type = 'R'
and exists(
select 1
from all_constraints
where constraint_name=a.r_constraint_name
and constraint_type in ('P', 'U')
and table_name = :OBJECT_NAME
and owner = :OBJECT_OWNER)
order by table_name, constraint_name]]>
</sql>
</query>
</item>
</items>
Add the extension to SQL Developer:
Navigate to any table and you should now see an additional tab next to SQL one, labelled FK References, which displays the new FK information.
Reference
The PATH solution has the issue that if $(npm bin) is placed in your .profile/.bashrc/etc it is evaluated once and is forever set to whichever directory the path was first evaluated in. If instead you modify the current path then every time you run the script your path will grow.
To get around these issues, I create a function and used that. It doesn't modify your environment and is simple to use:
function npm-exec {
$(npm bin)/$@
}
This can then be used like this without making any changes to your environment:
npm-exec r.js <args>
This is the difference between accessing the name and binding it within a scope.
If you're just looking up a variable to read its value, you've got access to global as well as local scope.
However if you assign to a variable who's name isn't in local scope, you are binding that name into this scope (and if that name also exists as a global, you'll hide that).
If you want to be able to assign to the global name, you need to tell the parser to use the global name rather than bind a new local name - which is what the 'global' keyword does.
Binding anywhere within a block causes the name everywhere in that block to become bound, which can cause some rather odd looking consequences (e.g. UnboundLocalError suddenly appearing in previously working code).
>>> a = 1
>>> def p():
print(a) # accessing global scope, no binding going on
>>> def q():
a = 3 # binding a name in local scope - hiding global
print(a)
>>> def r():
print(a) # fail - a is bound to local scope, but not assigned yet
a = 4
>>> p()
1
>>> q()
3
>>> r()
Traceback (most recent call last):
File "<pyshell#35>", line 1, in <module>
r()
File "<pyshell#32>", line 2, in r
print(a) # fail - a is bound to local scope, but not assigned yet
UnboundLocalError: local variable 'a' referenced before assignment

You will need these imports...
import javax.servlet.*;
import javax.servlet.http.*;
And, if you're using Maven, you'll also need this in the dependencies block of the pom.xml file in your project's base directory.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>

I was missing modal-dialog
that's why my close modal wasn't working properly.
This worked for me. There are 2 major categories of restrictions under api key settings:
Application restrictions
API restrictions
At the bottom in the Referrer section add your website url " http://www.grupocamaleon.com/boceto/aerial-simple.html " .There are example rules on the right hand side of the section based on various requirements.
Under API restrictions you have to explicitly select 'Maps Javascript API' from the dropdown list since our unique key will only be used for calling the Google maps API(probably) and save it as you can see in the below snap. I hope this works for you.....worked for me
Also the issue may arise due to improper key feeding inside the script tag. It should be something like:
<script async defer src="https://maps.googleapis.com/maps/api/jskey=YOUR_API_KEY&callback=initMap"
type="text/javascript"></script>
How to update in codeignitor?
whenever you want to update same status with multiple rows you use where_in insteam of where or if you want to change only single record can use where.
below is my code
$conditionArray = array(1, 3, 4, 6);
$this->db->where_in("ip_id", $conditionArray);
$this->db->update($this->table, array("status" => 'active'));
its working perfect.
I fought with this problem for a few hours before stumbling on the obvious answer. The problem I had was I was using different ssh implementations between when I generated my keys and when I used git.
I used ssh-keygen from the command prompt to generate my keys and but when I tried "git clone ssh://..." I got the same results as you, a prompt for the password and the message "fatal: The remote end hung up unexpectedly".
Determine which ssh windows is using by executing the Windows "where" command.
C:\where ssh
C:\Program Files (x86)\Git\bin\ssh.exe
The second line tells you which exact program will be executed.
Next you need to determine which ssh that git is using. Find this by:
C:\set GIT_SSH
GIT_SSH=C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe
And now you see the problem.
To correct this simply execute:
C:\set GIT_SSH=C:\Program Files (x86)\Git\bin\ssh.exe
To check if changes are applied:
C:\set GIT_SSH
GIT_SSH=C:\Program Files (x86)\Git\bin\ssh.exe
Now git will be able to use the keys that you generated earlier.
This fix is so far only for the current window. To fix it completely you need to change your environment variable.
Now any future command windows you open will have the correct settings.
Hope this helps.
Try below code:
alert.setTitle(R.string.WtsOnYourMind);
final EditText input = new EditText(context);
input.setHeight(100);
input.setWidth(340);
input.setGravity(Gravity.LEFT);
input.setImeOptions(EditorInfo.IME_ACTION_DONE);
alert.setView(input);
Left bit shifting to multiply by any power of two. Right bit shifting to divide by any power of two.
x = x << 5; // Left shift
y = y >> 5; // Right shift
In C/C++ it can be written as,
#include <math.h>
x = x * pow(2, 5);
y = y / pow(2, 5);
Yes, you can do that, but only if #b
is after #a
in the HTML.
If #b
comes immediately after #a
: http://jsfiddle.net/u7tYE/
#a:hover + #b {
background: #ccc
}
<div id="a">Div A</div>
<div id="b">Div B</div>
That's using the adjacent sibling combinator (+
).
If there are other elements between #a
and #b
, you can use this: http://jsfiddle.net/u7tYE/1/
#a:hover ~ #b {
background: #ccc
}
<div id="a">Div A</div>
<div>random other elements</div>
<div>random other elements</div>
<div>random other elements</div>
<div id="b">Div B</div>
That's using the general sibling combinator (~
).
Both +
and ~
work in all modern browsers and IE7+
If #b
is a descendant of #a
, you can simply use #a:hover #b
.
ALTERNATIVE: You can use pure CSS to do this by positioning the second element before the first. The first div is first in markup, but positioned to the right or below the second. It will work as if it were a previous sibling.

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.
To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency
or UIViewRoot#addComponentResource()
) the following way:
<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />
It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.
This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css
resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css
, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.
Also, when you're using a custom ResourceHandler
, you can also apply more finer grained control over resources coming from a specific library when library
is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler
ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler
and GraphicResourceHandler
; check the createResource()
method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource
or GraphicResource
for the purpose.
Noted should be that RichFaces did it wrong. It didn't use any library
at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander
had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.
Your own webapp does not necessarily need a resource library. You'd best just omit it.
<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />
Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.
<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />
Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml
template file:
<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />
And a /WEB-INF/templates/admin.xhtml
template file:
<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />
For a real world example, check the OmniFaces showcase source code.
Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib
, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):
<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />
Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)*
pattern to denote the resource library version.
WebContent
|-- resources
| `-- default
| `-- 1_0
| |-- css
| | `-- style.css
| |-- img
| | `-- logo.png
| `-- js
| `-- script.js
:
When using this markup:
<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />
This will generate the following HTML with the library version as v
parameter:
<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&v=1_0" alt="" />
So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler
will automatically serve the resource from the highest version number, according to numerical ordering rules.
So, when copying/renaming resources/default/1_0/*
folder into resources/default/1_1/*
like follows:
WebContent
|-- resources
| `-- default
| |-- 1_0
| | :
| |
| `-- 1_1
| |-- css
| | `-- style.css
| |-- img
| | `-- logo.png
| `-- js
| `-- script.js
:
Then the last markup example would generate the following HTML:
<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&v=1_1" alt="" />
This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.
Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler
. See also How to use JSF versioning for resources in jar.
This now works for IE FF Chrome properly... I have not tested for other browsers though
$(document).ready(function(){
$('#txtInput').on("cut copy paste",function(e) {
e.preventDefault();
});
});
Edit: As pointed out by webeno, .bind()
is deprecated hence it is recommended to use .on()
instead.
When you #include
a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal
variable is defined in the source so it will work no matter how it's declared.
Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.
With HttpWebRequest.GetRequestStream
Code example from http://msdn.microsoft.com/en-us/library/d4cek6cc.aspx
string postData = "firstone=" + inputData;
ASCIIEncoding encoding = new ASCIIEncoding ();
byte[] byte1 = encoding.GetBytes (postData);
// Set the content type of the data being posted.
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
// Set the content length of the string being posted.
myHttpWebRequest.ContentLength = byte1.Length;
Stream newStream = myHttpWebRequest.GetRequestStream ();
newStream.Write (byte1, 0, byte1.Length);
From one of my own code:
var request = (HttpWebRequest)WebRequest.Create(uri);
request.Credentials = this.credentials;
request.Method = method;
request.ContentType = "application/atom+xml;type=entry";
using (Stream requestStream = request.GetRequestStream())
using (var xmlWriter = XmlWriter.Create(requestStream, new XmlWriterSettings() { Indent = true, NewLineHandling = NewLineHandling.Entitize, }))
{
cmisAtomEntry.WriteXml(xmlWriter);
}
try
{
return (HttpWebResponse)request.GetResponse();
}
catch (WebException wex)
{
var httpResponse = wex.Response as HttpWebResponse;
if (httpResponse != null)
{
throw new ApplicationException(string.Format(
"Remote server call {0} {1} resulted in a http error {2} {3}.",
method,
uri,
httpResponse.StatusCode,
httpResponse.StatusDescription), wex);
}
else
{
throw new ApplicationException(string.Format(
"Remote server call {0} {1} resulted in an error.",
method,
uri), wex);
}
}
catch (Exception)
{
throw;
}
By using Reflector, you can see, that Contains is implemented using IndexOf. Here's the implementation.
public bool Contains(string value)
{
return (this.IndexOf(value, StringComparison.Ordinal) >= 0);
}
So Contains is likely a wee bit slower than calling IndexOf directly, but I doubt that it will have any significance for the actual performance.
Here is a vanilla Java answer:
import java.net.http.HttpClient;
import java.net.http.HttpResponse;
import java.net.http.HttpRequest;
import java.net.http.HttpRequest.BodyPublishers;
...
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(targetUrl)
.header("Content-Type", "application/json")
.POST(BodyPublishers.ofString(requestBody))
.build();
HttpResponse response = client.send(request, HttpResponse.BodyHandlers.ofString());
String responseString = (String) response.body();
"line 1\nline 2\r\n...".replace('\n', '').replace('\r', '')
>>> 'line 1line 2...'
or you could always get geekier with regexps :)
have fun!
Keep in mind if you are wanting to test this component you will want to inject the window. Use the @Inject() function to inject the window object by naming it using a string token like detailed in this duplicate
You might find it useful to lookup the classes on oracle. Eg:
http://download.oracle.com/javase/1.4.2/docs/api/javax/swing/JFrame.html
There you can see that JFrame extends JComponent and JContainer.
JComponent is a a basic object that can be drawn, JContainer extends this so that you can add components to it. JPanel and JFrame both extend JComponent as you can add things to them. JFrame provides a window, whereas JPanel is just a panel that goes inside a window. If that makes sense.
I prefer to limit the number of retries, so that if there's a problem with that specific item you will eventually continue onto the next one, thus:
for i in range(100):
for attempt in range(10):
try:
# do thing
except:
# perhaps reconnect, etc.
else:
break
else:
# we failed all the attempts - deal with the consequences.
int space = 40;
printf("%*s", space, "Hello");
This statement will reserve a row of 40 characters, print string at the end of the row (removing extra spaces such that the total row length is constant at 40). Same can be used for characters and integers as follows:
printf("%*d", space, 10);
printf("%*c", space, 'x');
This method using a parameter to determine spaces is useful where a variable number of spaces is required. These statements will still work with integer literals as follows:
printf("%*d", 10, 10);
printf("%*c", 20, 'x');
printf("%*s", 30, "Hello");
Hope this helps someone like me in future.
A simple solution using fscanf
:
void read_ints (const char* file_name)
{
FILE* file = fopen (file_name, "r");
int i = 0;
fscanf (file, "%d", &i);
while (!feof (file))
{
printf ("%d ", i);
fscanf (file, "%d", &i);
}
fclose (file);
}
Is there maybe a way to grab the rendered page from the internet explorer rendering engine and send it to a PDF-Printer tool automatically?
This is how ActivePDF works, which is good means that you know what you'll get, and it actually has reasonable styling support.
It is also one of the few packages I found (when looking a few years back) that actually supports the various page-break CSS commands.
Unfortunately, the ActivePDF software is very frustrating - since it has to launch the IE browser in the background for conversions it can be quite slow, and it is not particularly stable either.
There is a new version currently in Beta which is supposed to be much better, but I've not actually had a chance to try it out, so don't know how much of an improvement it is.
assuming certain column names...
INSERT one
newToner = Toner(toner_id = 1,
toner_color = 'blue',
toner_hex = '#0F85FF')
dbsession.add(newToner)
dbsession.commit()
INSERT multiple
newToner1 = Toner(toner_id = 1,
toner_color = 'blue',
toner_hex = '#0F85FF')
newToner2 = Toner(toner_id = 2,
toner_color = 'red',
toner_hex = '#F01731')
dbsession.add_all([newToner1, newToner2])
dbsession.commit()
UPDATE
q = dbsession.query(Toner)
q = q.filter(Toner.toner_id==1)
record = q.one()
record.toner_color = 'Azure Radiance'
dbsession.commit()
or using a fancy one-liner using MERGE
record = dbsession.merge(Toner( **kwargs))
I suggest you use a readdir() function and then loop and include the files (see the 1st example on that page).
<mvc:resources mapping="/resources/**"
location="/, classpath:/WEB-INF/public-resources/"
cache-period="10000" />
Put the resources under: src/main/webapp/images/logo.png
and then access them via /resources/images/logo.png
.
In the war
they will be then located at images/logo.png
. So the first location (/
) form mvc:resources
will pick them up.
The second location (classpath:/WEB-INF/public-resources/
) in mvc:resources
(looks like you used some roo based template) can be to expose resources (for example js-files) form jars, if they are located in the directory WEB-INF/public-resources
in the jar.
First of all, if anyone is going to store any password in a file, I would make sure it's hashed. It's not the best security, but at least it will not be in plain text.
First, create the password and hash it:
echo "password123" | md5sum | cut -d '-' -f 1 > /tmp/secret
Now, create your program to use the hash. In this case, this little program receives user input for a password without echoing, and then converts it to hash to be compared with the stored hash. If it matches the stored hash, then access is granted:
#!/bin/bash
PASSWORD_FILE="/tmp/secret"
MD5_HASH=$(cat /tmp/secret)
PASSWORD_WRONG=1
while [ $PASSWORD_WRONG -eq 1 ]
do
echo "Enter your password:"
read -s ENTERED_PASSWORD
if [ "$MD5_HASH" != "$(echo $ENTERED_PASSWORD | md5sum | cut -d '-' -f 1)" ]; then
echo "Access Deniend: Incorrenct password!. Try again"
else
echo "Access Granted"
PASSWORD_WRONG=0
fi
done
Tried @RameshVel solution but I could not pass arguments in my console application. If anyone experiences the same problem here is a solution:
using System.Diagnostics;
Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;
cmd.Start();
cmd.StandardInput.WriteLine("echo Oscar");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
cmd.WaitForExit();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());
if (!string.IsNullOrEmpty(Request.Form["username"])) { ... }
username is the name of the input on the submitting page. The password can be obtained the same way. If its not null or empty, it exists, then log in the user (I don't recall the exact steps for ASP.NET Membership, assuming that's what you're using).
In SQL Developer ..Go to Preferences-->NLS-->and change your date format accordingly
I happen to miss spaces in my query and this error comes.
Ex: $sql= "SELECT * FROM";
$sql .= "table1";
Though the example might look simple, when coding complex queries, the probability for this error is high. I was missing space before word "table1".
You can suppress the compiler warnings and tell the generics that the code which you had written is legal according to it.
Example:
@SuppressWarnings("unchecked")
public List<ReservationMealPlan> retreiveMealPlan() {
List<ReservationMealPlan> list=new ArrayList<ReservationMealPlan>();
TestMenuService testMenuService=new TestMenuService(em, this.selectedInstance);
list = testMenuService.getMeal(reservationMealPlan);
return list;
}
For non-preemptive system,
waitingTime = startTime - arrivalTime
turnaroundTime = burstTime + waitingTime = finishTime- arrivalTime
startTime = Time at which the process started executing
finishTime = Time at which the process finished executing
You can keep track of the current time elapsed in the system(timeElapsed
). Assign all processors to a process in the beginning, and execute until the shortest process is done executing. Then assign this processor which is free to the next process in the queue. Do this until the queue is empty and all processes are done executing. Also, whenever a process starts executing, recored its startTime
, when finishes, record its finishTime
(both same as timeElapsed
). That way you can calculate what you need.
When you call this:
data = Top15[['Citable docs per Capita','Energy Supply per Capita']]
correlation = data.corr(method='pearson')
Since, DataFrame.corr() function performs pair-wise correlations, you have four pair from two variables. So, basically you are getting diagonal values as auto correlation (correlation with itself, two values since you have two variables), and other two values as cross correlations of one vs another and vice versa.
Either perform correlation between two series to get a single value:
from scipy.stats.stats import pearsonr
docs_col = Top15['Citable docs per Capita'].values
energy_col = Top15['Energy Supply per Capita'].values
corr , _ = pearsonr(docs_col, energy_col)
or, if you want a single value from the same function (DataFrame's corr):
single_value = correlation[0][1]
Hope this helps.
Try this one:
function show_sub(cat) {
var parent = cat,
sub = parent.getElementsByClassName('sub');
if (sub[0].style.display == 'inline'){
sub[0].style.display = 'none';
}
else {
sub[0].style.display = 'inline';
}
}
document.getElementById('cat').onclick = function(){
show_sub(this);
};?
and use this for IE6 & 7
if (typeof document.getElementsByClassName!='function') {
document.getElementsByClassName = function() {
var elms = document.getElementsByTagName('*');
var ei = new Array();
for (i=0;i<elms.length;i++) {
if (elms[i].getAttribute('class')) {
ecl = elms[i].getAttribute('class').split(' ');
for (j=0;j<ecl.length;j++) {
if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
ei.push(elms[i]);
}
}
} else if (elms[i].className) {
ecl = elms[i].className.split(' ');
for (j=0;j<ecl.length;j++) {
if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
ei.push(elms[i]);
}
}
}
}
return ei;
}
}
Try putting the call to axis
after all plotting commands.
You could do it like that:
File folder = new File("your/path");
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
System.out.println("File " + listOfFiles[i].getName());
} else if (listOfFiles[i].isDirectory()) {
System.out.println("Directory " + listOfFiles[i].getName());
}
}
Do you want to only get JPEG files or all files?
