mkmf
is part of the ruby1.9.1-dev
package. This package contains the header files needed for extension libraries for Ruby 1.9.1. You need to install the ruby1.9.1-dev
package by doing:
sudo apt-get install ruby1.9.1-dev
Then you can install Rails as per normal.
Generally it's easier to just do:
sudo apt-get install ruby-dev
For prevent an error "can't modify frozen string" for encoding a varible you can use: var.dup.force_encoding(Encoding::ASCII_8BIT)
or var.dup.force_encoding(Encoding::UTF_8)
Adding a StreamHandler without arguments goes to stderr instead of stdout. If some other process has a dependency on the stdout dump (i.e. when writing an NRPE plugin), then make sure to specify stdout explicitly or you might run into some unexpected troubles.
Here's a quick example reusing the assumed values and LOGFILE from the question:
import logging
from logging.handlers import RotatingFileHandler
from logging import handlers
import sys
log = logging.getLogger('')
log.setLevel(logging.DEBUG)
format = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
ch = logging.StreamHandler(sys.stdout)
ch.setFormatter(format)
log.addHandler(ch)
fh = handlers.RotatingFileHandler(LOGFILE, maxBytes=(1048576*5), backupCount=7)
fh.setFormatter(format)
log.addHandler(fh)
You can use the URL facade which lets you do calls to the URL generator
So you can do:
URL::to('/');
You can also use the application container:
$app->make('url')->to('/');
$app['url']->to('/');
App::make('url')->to('/');
Or inject the UrlGenerator:
<?php
namespace Vendor\Your\Class\Namespace;
use Illuminate\Routing\UrlGenerator;
class Classname
{
protected $url;
public function __construct(UrlGenerator $url)
{
$this->url = $url;
}
public function methodName()
{
$this->url->to('/');
}
}
The issue is that a notebooks is not a plain python file. The steps to import the .ipynb
file are outlined in the following: Importing notebook
I am pasting the code, so if you need it...you can just do a quick copy and paste. Notice that at the end I have the import primes
statement. You'll have to change that of course. The name of my file is primes.ipynb
. From this point on you can use the content inside that file as you would do regularly.
Wish there was a simpler method, but this is straight from the docs.

Very useful I had a slightly different scenario where I the request xml was itself the body of the POST and not a param. For that the following code can be used - Posting as an answer just in case anyone else having similar issue will benefit.
final HttpHeaders headers = new HttpHeaders();
headers.add("header1", "9998");
headers.add("username", "xxxxx");
headers.add("password", "xxxxx");
headers.add("header2", "yyyyyy");
headers.add("header3", "zzzzz");
headers.setContentType(MediaType.APPLICATION_XML);
headers.setAccept(Arrays.asList(MediaType.APPLICATION_XML));
final HttpEntity<MyXmlbeansRequestDocument> httpEntity = new HttpEntity<MyXmlbeansRequestDocument>(
MyXmlbeansRequestDocument.Factory.parse(request), headers);
final ResponseEntity<MyXmlbeansResponseDocument> responseEntity = restTemplate.exchange(url, HttpMethod.POST, httpEntity,MyXmlbeansResponseDocument.class);
log.info(responseEntity.getBody());
>>> x = "2342.34"
>>> float(x)
2342.3400000000001
There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).
If you cannot use TRUNCATE
(e.g. because of foreign key constraints) you can use an alter table after deleting all rows to restart the auto_increment:
ALTER TABLE mytable AUTO_INCREMENT = 1
NSLog(@"%.0f", [[UIScreen mainScreen] bounds].size.width);
NSLog(@"%.0f", [[UIScreen mainScreen] bounds].size.height);
I also faced the same problem a long time ago.
Here is the Solution
In Eclipse Click on "Windows"-->"Preferences"---->"Java"---> "Installed JREs"---->Select the JDK, click on "Edit".
Check your JDK path, is it according to your path in environmental variables defined in system. if not then change it to "path" defined directory.
Simple Solution::
use {nativeQuery=true} in your query.
for example
@Query(value = "select d.id,d.name,d.breed,d.origin from Dog d",nativeQuery = true)
List<Dog> findALL();
Add each
method in your NSArray category
, you gonna need it a lot
Code taken from ObjectiveSugar
- (void)each:(void (^)(id object))block {
[self enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
block(obj);
}];
}
Write Thread.sleep(1000);
it will make the thread sleep for 1000ms
Depending on the state your repository was in when you ran the command, the effects of git reset --hard
can range from trivial to undo, to basically impossible.
Below I have listed a range of different possible scenarios, and how you might recover from them.
This situation usually occurs when you run git reset
with an argument, as in git reset --hard HEAD~
. Don't worry, this is easy to recover from!
If you just ran git reset
and haven't done anything else since, you can get back to where you were with this one-liner:
git reset --hard @{1}
This resets your current branch whatever state it was in before the last time it was modified (in your case, the most recent modification to the branch would be the hard reset you are trying to undo).
If, however, you have made other modifications to your branch since the reset, the one-liner above won't work. Instead, you should run git reflog
<branchname>
to see a list of all recent changes made to your branch (including resets). That list will look something like this:
7c169bd master@{0}: reset: moving to HEAD~
3ae5027 master@{1}: commit: Changed file2
7c169bd master@{2}: commit: Some change
5eb37ca master@{3}: commit (initial): Initial commit
Find the operation in this list that you want to "undo". In the example above, it would be the first line, the one that says "reset: moving to HEAD~". Then copy the representation of the commit before (below) that operation. In our case, that would be master@{1}
(or 3ae5027
, they both represent the same commit), and run git reset --hard <commit>
to reset your current branch back to that commit.
git add
, but never committed. Now my changes are gone!This is a bit trickier to recover from. git does have copies of the files you added, but since these copies were never tied to any particular commit you can't restore the changes all at once. Instead, you have to locate the individual files in git's database and restore them manually. You can do this using git fsck
.
For details on this, see Undo git reset --hard with uncommitted files in the staging area.
git add
, and never committed. Now my changes are gone!Uh oh. I hate to tell you this, but you're probably out of luck. git doesn't store changes that you don't add or commit to it, and according to the documentation for git reset
:
--hard
Resets the index and working tree. Any changes to tracked files in the working tree since
<commit>
are discarded.
It's possible that you might be able to recover your changes with some sort of disk recovery utility or a professional data recovery service, but at this point that's probably more trouble than it's worth.
In order to get the value of the selected item you can do the following:
this.options[this.selectedIndex].text
Here the different options
of the select are accessed, and the SelectedIndex
is used to choose the selected one, then its text
is being accessed.

Problem occurs when we want to import CommonJS module into ES6 module codebase.
Before these flags we had to import CommonJS modules with star (* as something
) import:
// node_modules/moment/index.js
exports = moment
// index.ts file in our app
import * as moment from 'moment'
moment(); // not compliant with es6 module spec
// transpiled js (simplified):
const moment = require("moment");
moment();
We can see that *
was somehow equivalent to exports
variable. It worked fine, but it wasn't compliant with es6 modules spec. In spec, the namespace record in star import (moment
in our case) can be only a plain object, not callable (moment()
is not allowed).
With flag esModuleInterop
we can import CommonJS modules in compliance with es6
modules spec. Now our import code looks like this:
// index.ts file in our app
import moment from 'moment'
moment(); // compliant with es6 module spec
// transpiled js with esModuleInterop (simplified):
const moment = __importDefault(require('moment'));
moment.default();
It works and it's perfectly valid with es6 modules spec, because moment
is not namespace from star import, it's default import.
But how does it work? As you can see, because we did a default import, we called the default
property on a moment
object. But we didn't declare a default
property on the exports
object in the moment library. The key is the __importDefault
function. It assigns module (exports
) to the default
property for CommonJS modules:
var __importDefault = (this && this.__importDefault) || function (mod) {
return (mod && mod.__esModule) ? mod : { "default": mod };
};
As you can see, we import es6 modules as they are, but CommonJS modules are wrapped into an object with the default
key. This makes it possible to import defaults on CommonJS modules.
__importStar
does the similar job - it returns untouched esModules, but translates CommonJS modules into modules with a default
property:
// index.ts file in our app
import * as moment from 'moment'
// transpiled js with esModuleInterop (simplified):
const moment = __importStar(require("moment"));
// note that "moment" is now uncallable - ts will report error!
var __importStar = (this && this.__importStar) || function (mod) {
if (mod && mod.__esModule) return mod;
var result = {};
if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result["default"] = mod;
return result;
};
And what about allowSyntheticDefaultImports
- what is it for? Now the docs should be clear:
Allow default imports from modules with no default export. This does not affect code emit, just typechecking.
In moment
typings we don't have specified default export, and we shouldn't have, because it's available only with flag esModuleInterop
on. So allowSyntheticDefaultImports
will not report an error if we want to import default from a third-party module which doesn't have a default export.
I have been trying to attach an audio which should autoplay and will be hidden. It's very simple. Just a few lines of HTML and CSS. Check this out!! Here is the piece of code I used within the body.
<div id="player">
<audio controls autoplay hidden>
<source src="file.mp3" type="audio/mpeg">
unsupported !!
</audio>
</div>
This worked for me !
Reason why you cannot use function pointers to call member functions is that ordinary function pointers are usually just the memory address of the function.
To call a member function, you need to know two things:
Ordinary function pointers cannot store both. C++ member function pointers are used to store a), which is why you need to specify the instance explicitly when calling a member function pointer.
I prefer JAR Browser, it has a simple interface where you can browse multiple JARs, and search for a specific class across multiple JARs simultaneously.
You can also use
cd %localhost%
to set the directory to the folder the batch file was opened from. Your script would look like this:
@echo off
cd %localhost%
echo .> dblank.txt
Make sure you set the directory before you use the command to create the text file.
from django.http import QueryDict
def search(request):
if request.GET.\__contains__("q"):
message = 'You submitted: %r' % request.GET['q']
else:
message = 'You submitted nothing!'
return HttpResponse(message)
Use this way, django offical document recommended __contains__ method. See https://docs.djangoproject.com/en/1.9/ref/request-response/
check your branch on your repo. maybe someone delete it.
You could use the Laravel query builder, but this is not the best way to do it.
Check Wader's answer below for the Eloquent way - which is better as it allows you to check that there is actually a user that matches the email address, and handle the error if there isn't.
DB::table('users')
->where('email', $userEmail) // find your user by their email
->limit(1) // optional - to ensure only one record is updated.
->update(array('member_type' => $plan)); // update the record in the DB.
If you have multiple fields to update you can simply add more values to that array at the end.
startup chrome with --disable-web-security
On Windows:
chrome.exe --disable-web-security
On Mac:
open /Applications/Google\ Chrome.app/ --args --disable-web-security
This will allow for cross-domain requests.
I'm not aware of if this also works for local files, but let us know !
And mention, this does exactly what you expect, it disables the web security, so be careful with it.
The following is an instantiation of the various "just print it" suggestions. I found it instructive.
#include "stdio.h"
int main() {
static int x = 5;
static int *p = &x;
printf("(int) p => %d\n",(int) p);
printf("(int) p++ => %d\n",(int) p++);
x = 5; p = &x;
printf("(int) ++p => %d\n",(int) ++p);
x = 5; p = &x;
printf("++*p => %d\n",++*p);
x = 5; p = &x;
printf("++(*p) => %d\n",++(*p));
x = 5; p = &x;
printf("++*(p) => %d\n",++*(p));
x = 5; p = &x;
printf("*p++ => %d\n",*p++);
x = 5; p = &x;
printf("(*p)++ => %d\n",(*p)++);
x = 5; p = &x;
printf("*(p)++ => %d\n",*(p)++);
x = 5; p = &x;
printf("*++p => %d\n",*++p);
x = 5; p = &x;
printf("*(++p) => %d\n",*(++p));
return 0;
}
It returns
(int) p => 256688152
(int) p++ => 256688152
(int) ++p => 256688156
++*p => 6
++(*p) => 6
++*(p) => 6
*p++ => 5
(*p)++ => 5
*(p)++ => 5
*++p => 0
*(++p) => 0
I cast the pointer addresses to int
s so they could be easily compared.
I compiled it with GCC.
You can parse the string using Html Agility pack and get the InnerText.
HtmlDocument htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(@"<b> Hulk Hogan's Celebrity Championship Wrestling <font color=\"#228b22\">[Proj # 206010]</font></b> (Reality Series, )");
string result = htmlDoc.DocumentNode.InnerText;
Here is the PHP's version (input values are: $latitude
and $longitude
):
$latitude_pattern = '/\A[+-]?(?:90(?:\.0{1,18})?|\d(?(?<=9)|\d?)\.\d{1,18})\z/x';
$longitude_pattern = '/\A[+-]?(?:180(?:\.0{1,18})?|(?:1[0-7]\d|\d{1,2})\.\d{1,18})\z/x';
if (preg_match($latitude_pattern, $latitude) && preg_match($longitude_pattern, $longitude)) {
// Valid coordinates.
}
Use os.path.join to combine the path to the Documents
directory with the completeName
(filename?) supplied by the user.
import os
with open(os.path.join('/path/to/Documents',completeName), "w") as file1:
toFile = raw_input("Write what you want into the field")
file1.write(toFile)
If you want the Documents
directory to be relative to the user's home directory, you could use something like:
os.path.join(os.path.expanduser('~'),'Documents',completeName)
Others have proposed using os.path.abspath
. Note that os.path.abspath
does not resolve '~'
to the user's home directory:
In [10]: cd /tmp
/tmp
In [11]: os.path.abspath("~")
Out[11]: '/tmp/~'
Use __new__
to return value from a class.
As others suggest __repr__
,__str__
or even __init__
(somehow) CAN give you what you want, But __new__
will be a semantically better solution for your purpose since you want the actual object to be returned and not just the string representation of it.
Read this answer for more insights into __str__
and __repr__
https://stackoverflow.com/a/19331543/4985585
class MyClass():
def __new__(cls):
return list() #or anything you want
>>> MyClass()
[] #Returns a true list not a repr or string
Just Close the opened file where you are going to write.
Take a look at crypto.createHash(algorithm)
var filename = process.argv[2];
var crypto = require('crypto');
var fs = require('fs');
var md5sum = crypto.createHash('md5');
var s = fs.ReadStream(filename);
s.on('data', function(d) {
md5sum.update(d);
});
s.on('end', function() {
var d = md5sum.digest('hex');
console.log(d + ' ' + filename);
});
Response status comes as second parameter in callback, (from docs):
// Simple GET request example :
$http.get('/someUrl').
success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
}).
error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
You could also put non-breaking spaces (&nbsp;) in lieu of the spaces so that they're forced to stay together.
How do I wrap this line of text
- asked by Peter 2 days ago
To center it, you can use the technique shown here: Absolute centering.
To make it as big as possible, give it max-width
and max-height
of 100%
.
To maintain the aspect ratio (even when the width is specifically set like in the snippet below), use object-fit
as explained here.
.className {
max-width: 100%;
max-height: 100%;
bottom: 0;
left: 0;
margin: auto;
overflow: auto;
position: fixed;
right: 0;
top: 0;
-o-object-fit: contain;
object-fit: contain;
}

It's better to avoid any kind of loops, just remove all elements directly like this:
$("#mytable > tbody").html("");
we can simply copy the code from tostring of object class to get the reference of string
class Test
{
public static void main(String args[])
{
String a="nikhil"; // it stores in String constant pool
String s=new String("nikhil"); //with new stores in heap
System.out.println(Integer.toHexString(System.identityHashCode(a)));
System.out.println(Integer.toHexString(System.identityHashCode(s)));
}

If you're using jQueryUI - there is an onDrag event. If you're not, then attach your listener to mouseup(), not click().
From: http://nginx.org/r/large_client_header_buffers
Syntax:
large_client_header_buffers
number
size
;
Default:large_client_header_buffers 4 8k;
Context: http, serverSets the maximum
number
andsize
of buffers used for reading large client request header. A request line cannot exceed the size of one buffer, or the 414 (Request-URI Too Large) error is returned to the client. A request header field cannot exceed the size of one buffer as well, or the 400 (Bad Request) error is returned to the client. Buffers are allocated only on demand. By default, the buffer size is equal to 8K bytes. If after the end of request processing a connection is transitioned into the keep-alive state, these buffers are released.
so you need to change the size parameter at the end of that line to something bigger for your needs.

Note that I don't know what the name of your Bumble Bee font or file is, so adjust accordingly, and that the font-face declaration should precede (come before) your use of it, as I've shown above.
Q. Can I still use the other
@font-face
typeface "GestaRegular" as well? Can I use both in the same stylesheet?
Just list them together as I've shown in my example. There is no reason you can't declare both. All that @font-face
does is instruct the browser to download and make a font-family available. See: http://iliadraznin.com/2009/07/css3-font-face-multiple-weights

Use isset()
$matchFound = (isset($_GET["id"]) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';
EDIT: This is added for the completeness sake. $_GET in php is a reserved variable that is an associative array. Hence, you could also make use of 'array_key_exists(mixed $key, array $array)'. It will return a boolean that the key is found or not. So, the following also will be okay.
$matchFound = (array_key_exists("id", $_GET)) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';
It looks like window.open
will take a Data URI as the location parameter.
So you can open it like this from the question: Opening PDF String in new window with javascript:
window.open("data:application/pdf;base64, " + base64EncodedPDF);
Here's an runnable example in plunker, and sample pdf file that's already base64 encoded.
Then on the server, you can convert the byte array to base64 encoding like this:
string fileName = @"C:\TEMP\TEST.pdf";
byte[] pdfByteArray = System.IO.File.ReadAllBytes(fileName);
string base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);
NOTE: This seems difficult to implement in IE because the URL length is prohibitively small for sending an entire PDF.
There are certain scenarios in which you can follow the steps suggested in the other answers, verify that Execution Policy is set correctly, and still have your scripts fail. If this happens to you, you are probably on a 64-bit machine with both 32-bit and 64-bit versions of PowerShell, and the failure is happening on the version that doesn't have Execution Policy set. The setting does not apply to both versions, so you have to explicitly set it twice.
Look in your Windows directory for System32 and SysWOW64.
Repeat these steps for each directory:
Check the current setting for ExecutionPolicy:
Get-ExecutionPolicy -List
Set the ExecutionPolicy for the level and scope you want, for example:
Set-ExecutionPolicy -Scope LocalMachine Unrestricted
Note that you may need to run PowerShell as administrator depending on the scope you are trying to set the policy for.

You are using:
In PostgreSQL 9.1, the idle connections with following query. It helped me to ward off the situation which warranted in restarting the database. This happens mostly with JDBC connections opened and not closed properly.
SELECT
pg_terminate_backend(procpid)
FROM
pg_stat_activity
WHERE
current_query = '<IDLE>'
AND
now() - query_start > '00:10:00';
Try Chrome Cache View from NirSoft (free).
If problem persists after trying any of the above solutions, Restart your server once. It worked for me :)
You can use backslash either way;
string str = "He said to me, \"Hello World\". How are you?";
It prints;
He said to me, "Hello World". How are you?
which is exactly same prints with;
string str = @"He said to me, ""Hello World"". How are you?";
Here is a DEMO
.
"
is still part of your string.

and String literals

In SQL Server 2016 (13.x) and above
DROP TABLE IF EXISTS dbo.Scores
In earlier versions
IF OBJECT_ID('dbo.Scores', 'U') IS NOT NULL
DROP TABLE dbo.Scores;
U is your table type
ex: url/:id
var sample= app.controller('sample', function ($scope, $routeParams) {
$scope.init = function () {
var qa_id = $routeParams.qa_id;
}
});
Using symfony 2.3 with php 5.5 and using the built in server with
app/console server:run
which should output something like:
Server running on http://127.0.0.1:8000
Quit the server with CONTROL-C.
then go to http://127.0.0.1:8000/app_dev.php/app/example
this should give you the default, which you can also find the default route by viewing src/AppBundle/Controller/DefaultController.php
Just in case you just need to show a picture in response to a camera request, there is image-to-camera.
Just download, build, install, copy an image of your choice to the device, and you can select it via the app, which is an alternative to the built-in camera.
CASE
is an expression - it returns a single scalar value (per row). It can't return a complex part of the parse tree of something else, like an ORDER BY
clause of a SELECT
statement.
It looks like you just need:
ORDER BY
CASE WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount END desc,
CASE WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount END desc,
Case WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount END DESC,
CASE WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount END DESC,
Case WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount END DESC,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC
Or possibly:
ORDER BY
CASE
WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC
It's a little tricky to tell which of the above (or something else) is what you're looking for because you've a) not explained what actual sort order you're trying to achieve, and b) not supplied any sample data and expected results, from which we could attempt to deduce the actual sort order you're trying to achieve.
This may be the answer we're looking for:
ORDER BY
CASE
WHEN TblList.PinRequestCount <> 0 THEN 5
WHEN TblList.HighCallAlertCount <> 0 THEN 4
WHEN TblList.HighAlertCount <> 0 THEN 3
WHEN TblList.MediumCallAlertCount <> 0 THEN 2
WHEN TblList.MediumAlertCount <> 0 THEN 1
END desc,
CASE
WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC
The memorystream class does this job pretty nicely for me. I couldn't get the buffer class to run as fast as memorystream.
using (MemoryStream ms = new MemoryStream())
{
ms.Write(BitConverter.GetBytes(22),0,4);
ms.Write(BitConverter.GetBytes(44),0,4);
ms.ToArray();
}
The above answer didn't work with Angular 6. So following is how I resolved it. Lets say this is how I defined my input box -
<input type="number" id="myTextBox" name="myTextBox"_x000D_
[(ngModel)]="response.myTextBox"_x000D_
#myTextBox="ngModel">
_x000D_
To check if the field is empty or not this should be the script.
<div *ngIf="!myTextBox.value" style="color:red;">_x000D_
Your field is empty_x000D_
</div>
_x000D_
Do note the subtle difference between the above answer and this answer. I have added an additional attribute .value
after my input name myTextBox
.
I don't know if the above answer worked for above version of Angular, but for Angular 6 this is how it should be done.
Some more explanation on why this check works; when there is no value present in the input box the default value of myTextBox.value
will be undefined
. As soon as you enter some text, your text becomes the new value of myTextBox.value
.
When your check is !myTextBox.value
it is checking that the value is undefined or not, it is equivalent to myTextBox.value == undefined
.
The specific problem is that you're declaring a new variable instead of assigning to an existing one:
char * ret = new char[strlen(array) + 1 + 1];
^^^^^^ Remove this
and trying to compare string values by comparing pointers:
if (array!="") // Wrong - compares pointer with address of string literal
if (array[0] == 0) // Better - checks for empty string
although there's no need to make that comparison at all; the first branch will do the right thing whether or not the string is empty.
The more general problem is that you're messing around with nasty, error-prone C-style string manipulation in C++. Use std::string
and it will manage all the memory allocation for you:
std::string appendCharToString(std::string const & s, char a) {
return s + a;
}
The simpler way is:
DELETE TableA
FROM TableB
WHERE TableA.ID = TableB.ID
For me, only setting CUDA_VISIBLE_DEVICES
to precisely -1
works:
Works:
import os
import tensorflow as tf
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'
if tf.test.gpu_device_name():
print('GPU found')
else:
print("No GPU found")
# No GPU found
Does not work:
import os
import tensorflow as tf
os.environ['CUDA_VISIBLE_DEVICES'] = ''
if tf.test.gpu_device_name():
print('GPU found')
else:
print("No GPU found")
# GPU found

ImageButton imagetrans=(ImageButton)findViewById(R.id.ImagevieID);

Springboot (via Spring) now makes adding to existing resource handlers easy. See Dave Syers answer. To add to the existing static resource handlers, simply be sure to use a resource handler path that doesn't override existing paths.
The two "also" notes below are still valid.
. . .
[Edit: The approach below is no longer valid]
If you want to extend the default static resource handlers, then something like this seems to work:
@Configuration
@AutoConfigureAfter(DispatcherServletAutoConfiguration.class)
public class CustomWebMvcAutoConfig extends
WebMvcAutoConfiguration.WebMvcAutoConfigurationAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
String myExternalFilePath = "file:///C:/Temp/whatever/m/";
registry.addResourceHandler("/m/**").addResourceLocations(myExternalFilePath);
super.addResourceHandlers(registry);
}
}
The call to super.addResourceHandlers
sets up the default handlers.
Also:

Python 3.4 introduced the pathlib
module into the standard library, which provides an object oriented approach to handle filesystem paths. The is_dir()
and exists()
methods of a Path
object can be used to answer the question:
In [1]: from pathlib import Path
In [2]: p = Path('/usr')
In [3]: p.exists()
Out[3]: True
In [4]: p.is_dir()
Out[4]: True
Paths (and strings) can be joined together with the /
operator:
In [5]: q = p / 'bin' / 'vim'
In [6]: q
Out[6]: PosixPath('/usr/bin/vim')
In [7]: q.exists()
Out[7]: True
In [8]: q.is_dir()
Out[8]: False
Pathlib is also available on Python 2.7 via the pathlib2 module on PyPi.

Yes, but don't - escaping forward slashes is a good thing. When using JSON inside <script>
tags it's necessary as a </script>
anywhere - even inside a string - will end the script tag.
Depending on where the JSON is used it's not necessary, but it can be safely ignored.
If you have 2 versions of Python (eg: 2.7.x and 3.6), you need do:
pip3 install --upgrade pip setuptools wheel
for example, in my .zshrc file:
export PATH=/usr/local/Cellar/python@2/2.7.15/bin:/usr/local/Cellar/python/3.6.5/bin:$PATH
You can exec command pip --version
and pip3 --version
check the pip from the special version. Because if don't add Python path to $PATH, and exec pip3 install --upgrade pip setuptools wheel
, your pip will be changed to pip from python3, but the pip should from python2.x
In case there are any morons out there like me, I had this frustrating problem because I forgot a simple

It's not exactly double precision because of how IEEE 754 works, and because binary doesn't really translate well to decimal. Take a look at the standard if you're interested.
The Home button is a very dangerous button to override and, because of that, Android will not let you override its behavior the same way you do the BACK button.
Take a look at this discussion.
You will notice that the home button seems to be implemented as a intent invocation, so you'll end up having to add an intent category to your activity. Then, any time the user hits home, your app will show up as an option. You should consider what it is you are looking to accomplish with the home button. If its not to replace the default home screen of the device, I would be wary of overloading the HOME button, but it is possible (per discussion in above thread.)
I would just go with
<tr @(if (count++ % 2 == 0){<text>class="alt-row"</text>})>
Or even better
<tr class="alt-row@(count++ % 2)">
this will give you lines like
<tr class="alt-row0">
<tr class="alt-row1">
<tr class="alt-row0">
<tr class="alt-row1">
Postgresql12
from sql file: pg_restore -d database < file.sql
from custom format file: pg_restore -Fc database < file.dump
You should also consider changing some of your rules to:
With the above improvements, and for more flexibility and readability, I would modify the regex to.
^(?=(.*[a-z]){3,})(?=(.*[A-Z]){2,})(?=(.*[0-9]){2,})(?=(.*[!@#$%^&*()\-__+.]){1,}).{8,}$
Basic Explanation
(?=(.*RULE){MIN_OCCURANCES,})
Each rule block is shown by (?=(){}). The rule and number of occurrences can then be easily specified and tested separately, before getting combined
Detailed Explanation
^ start anchor
(?=(.*[a-z]){3,}) lowercase letters. {3,} indicates that you want 3 of this group
(?=(.*[A-Z]){2,}) uppercase letters. {2,} indicates that you want 2 of this group
(?=(.*[0-9]){2,}) numbers. {2,} indicates that you want 2 of this group
(?=(.*[!@#$%^&*()\-__+.]){1,}) all the special characters in the [] fields. The ones used by regex are escaped by using the \ or the character itself. {1,} is redundant, but good practice, in case you change that to more than 1 in the future. Also keeps all the groups consistent
{8,} indicates that you want 8 or more
$ end anchor
And lastly, for testing purposes here is a robulink with the above regex

If you prefer, you can set these options via the commmand line (instead of editing the config file) like so:
$ git config branch.master.remote origin
$ git config branch.master.merge refs/heads/master
Or, if you're like me, and want this to be the default across all of your projects, including those you might work on in the future, then add it as a global config setting:
$ git config --global branch.master.remote origin
$ git config --global branch.master.merge refs/heads/master
Here is how you can do it:
std::string & trim(std::string & str)
{
return ltrim(rtrim(str));
}
And the supportive functions are implemeted as:
std::string & ltrim(std::string & str)
{
auto it2 = std::find_if( str.begin() , str.end() , [](char ch){ return !std::isspace<char>(ch , std::locale::classic() ) ; } );
str.erase( str.begin() , it2);
return str;
}
std::string & rtrim(std::string & str)
{
auto it1 = std::find_if( str.rbegin() , str.rend() , [](char ch){ return !std::isspace<char>(ch , std::locale::classic() ) ; } );
str.erase( it1.base() , str.end() );
return str;
}
And once you've all these in place, you can write this as well:
std::string trim_copy(std::string const & str)
{
auto s = str;
return ltrim(rtrim(s));
}
Try this
Before removing a package from composer.json declaration, please remove cache

If you forget to remove cache and you get class not found error then please reinstall the package and clear cache and remove again.
So, static methods are the methods which can be called without creating the object of a class. For Example :-
@staticmethod
def add(a, b):
return a + b
b = A.add(12,12)
print b
In the above example method add
is called by the class name A
not the object name.
In my conclusion we have this:
Soap client side:
use only Suds-jurko (updated 2016)
suds is well maintained and updated.
UPDATE 06/2017: suds-jurko library is not updated and apparently abandoned,
I tested zeep library but got limitations around tokens, by now just support UsernameToken, i report a bug to create timestamp token and author update the code to fix it.
Zeep start good and has good documentation , so i recently migrated my code from suds to zeep and works fine.
Soap server side:
We have TGWS, soaplib (pysimplesoap not tested) IMHO use and help soaplib must be the choice.
Best regards,
Note that if you have a generic interface IMyInterface<T>
then this will always return false
:
typeof(IMyInterface<>).IsAssignableFrom(typeof(MyType)) /* ALWAYS FALSE */
This doesn't work either:
typeof(MyType).GetInterfaces().Contains(typeof(IMyInterface<>)) /* ALWAYS FALSE */
However, if MyType
implements IMyInterface<MyType>
this works and returns true
:
typeof(IMyInterface<MyType>).IsAssignableFrom(typeof(MyType))
However, you likely will not know the type parameter T
at runtime. A somewhat hacky solution is:
typeof(MyType).GetInterfaces()
.Any(x=>x.Name == typeof(IMyInterface<>).Name)
Jeff's solution is a bit less hacky:
typeof(MyType).GetInterfaces()
.Any(i => i.IsGenericType
&& i.GetGenericTypeDefinition() == typeof(IMyInterface<>));
Here's a extension method on Type
that works for any case:
public static class TypeExtensions
{
public static bool IsImplementing(this Type type, Type someInterface)
{
return type.GetInterfaces()
.Any(i => i == someInterface
|| i.IsGenericType
&& i.GetGenericTypeDefinition() == someInterface);
}
}
(Note that the above uses linq, which is probably slower than a loop.)
You can then do:
typeof(MyType).IsImplementing(IMyInterface<>)
Usually that problem is that in the last iteration you have an empty object or undefine object. use console.log() inside you cicle to check that this doent happend.
Sometimes a prototype in some place add an extra element.
You could do all of that in one line by omitting the example
variable:
if "exam" in "example": print "yes!"
This is worked for me.
#_account_id{
display: none;
}
label[for="_account_id"] { display: none !important; }
As th function is not using $this
at all, you can add a static
keyword just after public and then call
Functions::filter($_GET['params']);
Avoiding the creation of an object just for one method call
Python offers a stepping stone into the world of programming. Even though Python Programming Language has been around for 25 years, it is still rising in popularity. Some of the biggest advantage of Python are it's
As a general purpose programming language, Python can be used for multiple things. Python can be easily used for small, large, online and offline projects. The best options for utilizing Python are web development, simple scripting and data analysis. Below are a few examples of what Python will let you do:
Web Development:
You can use Python to create web applications on many levels of complexity. There are many excellent Python web frameworks including, Pyramid, Django and Flask, to name a few.
Data Analysis:
Python is the leading language of choice for many data scientists. Python has grown in popularity, within this field, due to its excellent libraries including; NumPy and Pandas and its superb libraries for data visualisation like Matplotlib and Seaborn.
Machine Learning:
What if you could predict customer satisfaction or analyse what factors will affect household pricing or to predict stocks over the next few days, based on previous years data? There are many wonderful libraries implementing machine learning algorithms such as Scikit-Learn, NLTK and TensorFlow.
Computer Vision:
You can do many interesting things such as Face detection, Color detection while using Opencv and Python.
Internet Of Things With Raspberry Pi:
Raspberry Pi is a very tiny and affordable computer which was developed for education and has gained enormous popularity among hobbyists with do-it-yourself hardware and automation. You can even build a robot and automate your entire home. Raspberry Pi can be used as the brain for your robot in order to perform various actions and/or react to the environment. The coding on a Raspberry Pi can be performed using Python. The Possibilities are endless!
Game Development:
Create a video game using module Pygame. Basically, you use Python to write the logic of the game. PyGame applications can run on Android devices.
Web Scraping:
If you need to grab data from a website but the site does not have an API to expose data, use Python to scraping data.
Writing Scripts:
If you're doing something manually and want to automate repetitive stuff, such as emails, it's not difficult to automate once you know the basics of this language.
Browser Automation:
Perform some neat things such as opening a browser and posting a Facebook status, you can do it with Selenium with Python.
GUI Development:
Build a GUI application (desktop app) using Python modules Tkinter, PyQt to support it.
Rapid Prototyping:
Python has libraries for just about everything. Use it to quickly built a (lower-performance, often less powerful) prototype. Python is also great for validating ideas or products for established companies and start-ups alike.
Python can be used in so many different projects. If you're a programmer looking for a new language, you want one that is growing in popularity. As a newcomer to programming, Python is the perfect choice for learning quickly and easily.
I didn't see this method shown, so if someone else is looking to do this I found that ggplot documentation suggested a technique for using the gam
method that produced similar results to loess
when working with small data sets.
library(ggplot2)
x <- 1:10
y <- c(2,4,6,8,7,8,14,16,18,20)
df <- data.frame(x,y)
r <- ggplot(df, aes(x = x, y = y)) + geom_smooth(method = "gam", formula = y ~ s(x, bs = "cs"))+geom_point()
r
First with the loess method and auto formula Second with the gam method with suggested formula
$().ready(docReady);
function docReady() {
$("#myTextbox").focusout(uCaseMe);
}
function uCaseMe() {
var val = $(this).val().toUpperCase();
// Reset the current value to the Upper Case Value
$(this).val(val);
}
This is a reusable approach. Any number of textboxes can be done this way w/o naming them. A page wide solution could be achieved by changing the selector in docReady.
My example uses lost focus, the question did not specify as they type. You could trigger on change if thats important in your scenario.
$full_path = WP_PLUGIN_URL . '/'. str_replace( basename( __FILE__ ), "", plugin_basename(__FILE__) );
This link may help: http://codex.wordpress.org/Determining_Plugin_and_Content_Directories.
Actually this is not really the answer of the question, but this is a better way to do it.
I suggest you to use connect/express as http server, since they save you a lot of time. You obviously don't want to reinvent the wheel. In your case session management is much easier with connect/express.
Beside that for authentication I suggest you to use everyauth. Which supports a lot of authentication strategies. Awesome for rapid development.
All this can be easily down with some copy pasting from their documentation!
Just set the style
:
var menu = document.createElement("select");
menu.style.width = "100px";
Or if you like, you can use jQuery:
$(menu).css("width", "100px");
I'd like to add to the right and successful answers, that if you initialize a view with visibility as View.GONE
, the view could have been not initialized and you will get some random errors.
For example if you initialize a layout as View.GONE
and then you try to start an animation, from my experience I've got my animation working randomly times. Sometimes yes, sometimes no.
So before handling (resizing, move, whatever) a view, you have to init it as View.VISIBLE
or View.INVISIBLE
to render it (draw it) in the screen, and then handle it.
Wrap into an object
Something like this is a bit cleaner
const obj = {
X: 'dataX',
Y: 'dataY',
//...
}
const list = {
A: true && 'dataA',
B: false && 'dataB',
C: 'A' != 'B' && 'dataC',
D: 2000 < 100 && 'dataD',
// E: conditionE && 'dataE',
// F: conditionF && 'dataF',
//...
}
Object.keys(list).map(prop => list[prop] ? obj[prop] = list[prop] : null)
Wrap into an array
Or if you want to use Jamie Hill's method and have a very long list of conditions then you must write ...
syntax multiple times. To make it a bit cleaner, you can just wrap them into an array, then use reduce()
to return them as a single object.
const obj = {
X: 'dataX',
Y: 'dataY',
//...
...[
true && { A: 'dataA'},
false && { B: 'dataB'},
'A' != 'B' && { C: 'dataC'},
2000 < 100 && { D: 'dataD'},
// conditionE && { E: 'dataE'},
// conditionF && { F: 'dataF'},
//...
].reduce(( v1, v2 ) => ({ ...v1, ...v2 }))
}
Or using map()
function
const obj = {
X: 'dataX',
Y: 'dataY',
//...
}
const array = [
true && { A: 'dataA'},
false && { B: 'dataB'},
'A' != 'B' && { C: 'dataC'},
2000 < 100 && { D: 'dataD'},
// conditionE && { E: 'dataE'},
// conditionF && { F: 'dataF'},
//...
].map(val => Object.assign(obj, val))
In the later PHP version self::staticMethod();
also will not work. It will throw the strict standard error.
In this case, we can create object of same class and call by object
here is the example
class Foo {
public function fun1() {
echo 'non-static';
}
public static function fun2() {
echo (new self)->fun1();
}
}
look also hier:
NET START | FIND "Service name" > nul IF errorlevel 1 ECHO The service is not running
just copied from: http://ss64.com/nt/sc.html
node -v

If you try to console log query object directly you will get error TypeError: Cannot convert object to primitive value
So I would suggest use JSON.stringify
const http = require('http');
const url = require('url');
const server = http.createServer((req, res) => {
const parsedUrl = url.parse(req.url, true);
const path = parsedUrl.pathname, query = parsedUrl.query;
const method = req.method;
res.end("hello world\n");
console.log(`Request received on: ${path} + method: ${method} + query:
${JSON.stringify(query)}`);
console.log('query: ', query);
});
server.listen(3000, () => console.log("Server running at port 3000"));
So doing curl http://localhost:3000/foo\?fizz\=buzz
will return Request received on: /foo + method: GET + query: {"fizz":"buzz"}
The problem is that there is no class called com.service.SempediaSearchManager
on your webapp's classpath. The most likely root causes are:
the fully qualified classname is incorrect in /WEB-INF/Sempedia-service.xml
; i.e. the class name is something else,
the class is not in your webapp's /WEB-INF/classes
directory tree or a JAR file in the /WEB-INF/lib
directory.
EDIT : The only other thing that I can think of is that the ClassDefNotFoundException
may actually be a result of an earlier class loading / static initialization problem. Check your log files for the first stack trace, and look the nested exceptions, i.e. the "caused by" chain. [If a class load fails one time and you or Spring call Class.forName()
again for some reason, then Java won't actually try to load a second time. Instead you will get a ClassDefNotFoundException
stack trace that does not explain the real cause of the original failure.]
If you are still stumped, you should take Eclipse out of the picture. Create the WAR file in the form that you are eventually going to deploy it, then from the command line:
manually shutdown Tomcat
clean out your Tomcat webapp directory,
copy the WAR file into the webapp directory,
start Tomcat.
If that doesn't solve the problem directly, look at the deployed webapp directory on Tomcat to verify that the "missing" class is in the right place.
To change the font awesome icons color for your entire project use this in your css
.fa {
color : red;
}
You need to add a reference to the .NET assembly System.Data.Entity.dll.
In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$");
for further information see the javadoc
This error is because of multiple project having the offending resources.
Try out adding the dependencies projects other way around. (like in pom.xml or external depandancies)
Don't just enable the first occurrence of display_errors
in the php.ini file. Make sure you scroll down to the "real" setting and change it from Off
to On
.
The thing is that if you settle with changing (i.e. uncomment + add = On
) by the very first occurrence of display_errors
your changes will be overwritten somewhere on line 480 where it's set to Off
again.
This may or may not be a sub-optimal way of doing things, but the simplest solution to the multi-page problem I found was to ensure all rendering is done before calling the jsPDFObj.save method.
As for rendering hidden articles, this is solved with a similar fix to css image text replacement, I position absolutely the element to be rendered -9999px off the page left,
this doesn't affect layout and allows for the elem to be visible to html2pdf, especially when using tabs, accordions and other UI components that depend on {display: none}
.
This method wraps the prerequisites in a promise and calls pdf.save()
in the finally()
method. I cannot be sure that this is foolproof, or an anti-pattern, but it would seem that it works in most cases I have thrown at it.
// Get List of paged elements._x000D_

This function creates date from timestamp:
function formatDateTime(dateString) {
const parsed = moment(new Date(dateString))
if (!parsed.isValid()) {
return dateString
}
return parsed.format('MMM D, YYYY, HH:mmA')
}
To simply repeat the same letter 10 times:
string_val = "x" * 10 # gives you "xxxxxxxxxx"
And if you want something more complex, like n
random lowercase letters, it's still only one line of code (not counting the import statements and defining n
):
from random import choice
from string import ascii_lowercase
n = 10
string_val = "".join(choice(ascii_lowercase) for i in range(n))
Short answer to first question: yes.
Longer answer: maybe; it depends on whether the build process for SVMLight behaves itself on 64-bit windows.
Final note: that call to System.loadLibrary is silly. Either call System.load with a full pathname or let it search java.library.path.
I would use
\b[A-Za-z]*Id\b
The \b matches the beginning and end of a word i.e. space, tab or newline, or the beginning or end of a string.
The [A-Za-z] will match any letter, and the * means that 0+ get matched. Finally there is the Id.
Note that this will match words that have capital letters in the middle such as 'teStId'.
I use http://www.regular-expressions.info/ for regex reference
Here is what you do in Excel 2003:
Here is what you do in Excel 2007:
Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?
If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.
I had the same problem. Whole form (including gif) stopping to redraw itself because of long operation working in the background. Here is how i solved this.
private void MyThreadRoutine()
{
this.Invoke(this.ShowProgressGifDelegate);
//your long running process
System.Threading.Thread.Sleep(5000);
this.Invoke(this.HideProgressGifDelegate);
}
private void button1_Click(object sender, EventArgs e)
{
ThreadStart myThreadStart = new ThreadStart(MyThreadRoutine);
Thread myThread = new Thread(myThreadStart);
myThread.Start();
}
I simply created another thread to be responsible for this operation. Thanks to this initial form continues redrawing without problems (including my gif working). ShowProgressGifDelegate and HideProgressGifDelegate are delegates in form that set visible property of pictureBox with gif to true/false.
The ?
operand makes match non-greedy. E.g. .*
is greedy while .*?
isn't. So you can use something like <img.*?>
to match the whole tag. Or <img[^>]*>
.
But remember that the whole set of HTML can't be actually parsed with regular expressions.
This combination (and values near to these) seems to "magically" work for me to keep the colorbar scaled to the plot, no matter what size the display.
plt.colorbar(im,fraction=0.046, pad=0.04)
It also does not require sharing the axis which can get the plot out of square.
Create the column:
ALTER TABLE yourtable ADD COLUMN combined VARCHAR(50);
Update the current values:
UPDATE yourtable SET combined = CONCAT(zipcode, ' - ', city, ', ', state);
Update all future values automatically:
CREATE TRIGGER insert_trigger
BEFORE INSERT ON yourtable
FOR EACH ROW
SET new.combined = CONCAT(new.zipcode, ' - ', new.city, ', ', new.state);
CREATE TRIGGER update_trigger
BEFORE UPDATE ON yourtable
FOR EACH ROW
SET new.combined = CONCAT(new.zipcode, ' - ', new.city, ', ', new.state);

This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.
However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.
In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.
Here is a simple example based on a SAP system I have access to.
Public Sub SimpleSAPExport()
Set SapGuiAuto = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI
Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
Set session = SAPCon.Children(0) 'Get the first session (window) on that connection
'Start the transaction to view a table
session.StartTransaction "SE16"
'Select table T001
session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
session.findById("wnd[0]/tbar[1]/btn[7]").Press
'Set our selection criteria
session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
session.findById("wnd[0]/tbar[1]/btn[8]").press
'Click the export to file button
session.findById("wnd[0]/tbar[1]/btn[45]").press
'Choose the export format
session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
session.findById("wnd[1]/tbar[0]/btn[0]").press
'Choose the export filename
session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"
'Export the file
session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub
To help find the names of elements such aswnd[1]/tbar[0]/btn[0]
you can use script recording.
Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.
Within that the More
button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.
The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI")
defines the SapGuiAuto object.
If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx
in the SAP GUI installation folder.
In most cases, you shouldn't use a regex for that.
os.path.splitext(filename)[0]
This will also handle a filename like .bashrc
correctly by keeping the whole name.
I wrote all about tabs in vim, which gives a few interesting things you didn't ask about. To automatically indent braces, use:
:set cindent
To indent two spaces (instead of one tab of eight spaces, the vim default):
:set shiftwidth=2
To keep vim from converting eight spaces into tabs:
:set expandtab
If you ever want to change the indentation of a block of text, use < and >. I usually use this in conjunction with block-select mode (v, select a block of text, < or >).
(I'd try to talk you out of using two-space indentation, since I (and most other people) find it hard to read, but that's another discussion.)
It isn't possible to do it the way you've defined ldap_get
. However, if you define ldap_get
like this:
def ldap_get ( base_dn, filter, attrs=nil, scope=LDAP::LDAP_SCOPE_SUBTREE )
Now you can:
ldap_get( base_dn, filter, X )
But now you have problem that you can't call it with the first two args and the last arg (the same problem as before but now the last arg is different).
The rationale for this is simple: Every argument in Ruby isn't required to have a default value, so you can't call it the way you've specified. In your case, for example, the first two arguments don't have default values.
The error is:
Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])
In JSON, platforms
look like this:
"platforms": [
{
"platform": "iphone"
},
{
"platform": "ipad"
},
{
"platform": "android_phone"
},
{
"platform": "android_tablet"
}
]
So try change your pojo to something like this:
private List platforms;
public List getPlatforms(){
return this.platforms;
}
public void setPlatforms(List platforms){
this.platforms = platforms;
}
EDIT: you will need change mobile_networks
too. Will look like this:
private List mobile_networks;
public List getMobile_networks() {
return mobile_networks;
}
public void setMobile_networks(List mobile_networks) {
this.mobile_networks = mobile_networks;
}
My work uses Winnovative's PDF generator (We've used it mainly to convert HTML to PDF, but you can generate it other ways as well)
&

I am thinking this may not be possible in Java because annotation and its parameters are resolved at compile time.
With Seam 2 http://seamframework.org/ you were able to resolve annotation parameters at runtime, with expression language inside double quotes.

When using kill -3 one should see the thread dump in the standard output. Most of the application servers write the standard output to a separate file. You should find it there when using kill -3. There are multiple ways of getting thread dumps:
kill -3 <PID>
: Gives output to standard output.For hotspot VM's we can also use jstack
command to generate a thread dump. It’s a part of the JDK. Syntax is as follows:
Usage:
jstack [-l] <pid> (to connect to running process)
jstack -F [-m] [-l] <pid>(to connect to a hung process)
- For JRockit JVM we can use JRCMD command which comes with JDK Syntax:
jrcmd <jrockit pid> [<command> [<arguments>]] [-l] [-f file] [-p] -h]
You can use StringBuffer
or StringBuilder
for this. Both are for dynamic string manipulation. StringBuffer
is thread-safe where as StringBuilder
is not.
Use StringBuffer
in a multi-thread environment. But if it is single threaded StringBuilder
is recommended and it is much faster than StringBuffer
.

Execute the same git fetch/pull/push

This answer solves the problem by creating a duplicate annotated tag — including all tag info such as tagger, message, and tag date — by using the tag info from the existing tag.
SOURCE_TAG=old NEW_TAG=new; deref() { git for-each-ref \
"refs/tags/$SOURCE_TAG" --format="%($1)" ; }; \
GIT_COMMITTER_NAME="$(deref taggername)" \
GIT_COMMITTER_EMAIL="$(deref taggeremail)" \
GIT_COMMITTER_DATE="$(deref taggerdate)" git tag "$NEW_TAG" \
"$(deref "*objectname")" -a -m "$(deref contents)"
git tag -d old
git push origin new :old
Update the SOURCE_TAG
and NEW_TAG
values to match your old and new tag names.
From what I can tell, all the other answers have subtle gotchas, or don't fully duplicate everything about the tag (e.g. they use a new tag date, or the current user's info as the tagger). Many of them call out the re-tagging warning, despite that not applying to this scenario (it's for moving a tag name to a different commit, not for renaming to a differently named tag). I've done some digging, and I believe I've pieced together a solution that addresses these concerns.
The git-tag
documentation specifies the parts of an annotated tag. To truly be an indistinguishable rename, these elements should be the same in the new tag.
Tag objects (created with
-a
,-s
, or-u
) are called "annotated" tags; they contain a creation date, the tagger name and e-mail, a tagging message, and an optional GnuPG signature.
I'm only addressing unsigned tags in this answer, though it should be a simple matter to extend this solution to signed tags.
An annotated tag named old
is used in the example, and will be renamed to new
.
First, we need to get the information for the existing tag. This can be achieved using for-each-ref
:
Command:
git for-each-ref refs/tags --format="\
Tag name: %(refname:short)
Tag commit: %(objectname:short)
Tagger date: %(taggerdate)
Tagger name: %(taggername)
Tagger email: %(taggeremail)
Tagged commit: %(*objectname:short)
Tag message: %(contents)"
Output:
Tag commit: 88a6169
Tagger date: Mon Dec 14 12:44:52 2020 -0600
Tagger name: John Doe
Tagger email: <[email protected]>
Tagged commit: cda5b4d
Tag name: old
Tag message: Initial tag
Body line 1.
Body line 2.
Body line 3.
A duplicate tag with the new name can be created using the info gathered in step 1 from the existing tag.
The commit ID & commit message can be passed directly to git tag
.
The tagger information (name, email, and date) can be set using the git environment variables GIT_COMMITTER_NAME
, GIT_COMMITTER_EMAIL
, GIT_COMMITTER_DATE
. The date usage in this context is described in the On Backdating Tags documentation for git tag
; the other two I figured out through experimentation.
GIT_COMMITTER_NAME="John Doe" GIT_COMMITTER_EMAIL="[email protected]" \
GIT_COMMITTER_DATE="Mon Dec 14 12:44:52 2020 -0600" git tag new cda5b4d -a -m "Initial tag
Body line 1.
Body line 2.
Body line 3."
A side-by-side comparison of the two tags shows they're identical in all the ways that matter. The only thing that's differing here is the commit reference of the tag itself, which is expected since they're two different tags.
Command:
git for-each-ref refs/tags --format="\
Tag commit: %(objectname:short)
Tagger date: %(taggerdate)
Tagger name: %(taggername)
Tagger email: %(taggeremail)
Tagged commit: %(*objectname:short)

As a single command, including retrieving the current tag data:
SOURCE_TAG=old NEW_TAG=new; deref() { git for-each-ref "refs/tags/$SOURCE_TAG" --format="%($1)" ; }; GIT_COMMITTER_NAME="$(deref taggername)" GIT_COMMITTER_EMAIL="$(deref taggeremail)" GIT_COMMITTER_DATE="$(deref taggerdate)" git tag "$NEW_TAG" "$(deref "*objectname")" -a -m "$(deref contents)"
Next, the existing tag should be deleted locally. This step can be skipped if you wish to keep the old tag along with the new one (i.e. duplicate the tag rather than rename it).
git tag -d old
Assuming you're working from a remote repository, the changes can now be pushed using git push
:
git push origin new :old
This pushes the new
tag, and deletes the old
tag.
You can get a list of all globally installed modules using:

@Carlos: In his article Tim Bray recommends this (as does another post by Google), but unfortunately it is not being applied by all tablet manufacturers.
... We recommend that manufactures of large-form-factor devices remove "Mobile" from the User Agent...
Most Android tablet user-agent strings I've seen use mobile safari, e.g. the Samsung Galaxy Tab:
Mozilla/5.0 (Linux; U; Android 2.2; en-us; SCH-I800 Build/FROYO) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
So at the moment I am checking on device names to detect Android tablets. As long as there are just a few models on the market, that's ok but soon this will be an ugly solution.
At least in case of the XOOM, the mobile part seems to be gone:
Mozilla/5.0 (Linux; U; Android 3.0; en-us; Xoom Build/HRI39) AppleWebKit/534.13 (KHTML, like Gecko) Version/4.0 Safari/534.13
But as there are currently only tablets with Andorid 3.x, checking on Android 3 would be enough.
This is a modified version of Tim Post's method; I used /dev/tty instead of /dev/stdout. I don't know why it doesn't work with stdout (which is a link to /proc/self/fd/1):
freopen("log.txt","w",stdout);
...
...
freopen("/dev/tty","w",stdout);
By using /dev/tty the output is redirected to the terminal from where the app was launched.
Hope this info is useful.

All that metadata is held in the DB2 catalog tables in the SYSIBM
'schema'. It varies for the DB2/z mainframe product and the DB2/LUW distributed product but they're coming closer and closer with each release.
IBM conveniently place all their manuals up on the publib
site for the world to access. My area of expertise, DB2/z, has the pages you want here.
There are a number of tables there that you'll need to reference:
SYSTABLES for table information.
SYSINDEXES \
SYSINDEXPART + for index information.
SYSKEYS /
SYSCOLUMNS for column information.
The list of all information centers is here which should point you to the DB2/LUW version if that's your area of interest.
Honestly, this is the sort of situation where I just open up Python on the command line and start messing around:
>>> x = "Dana Larose is playing with find()"
>>> x.find("Dana")
0
>>> x.find("ana")
1
>>> x.find("La")
5
>>> x.find("La", 6)
-1
Python's interpreter makes this sort of experimentation easy. (Same goes for other languages with a similar interpreter)

If you're using Emacs, you can type C-x v ~

Maybe worth looking at QRGen, which is built on top of ZXing and supports UTF-8 with this kind of syntax:
// if using special characters don't forget to supply the encoding
VCard johnSpecial = new VCard("Jöhn D?e")
.setAdress("ëåäö? Sträät 1, 1234 Döestüwn");
QRCode.from(johnSpecial).withCharset("UTF-8").file();
Someone has already made a benchmark: jQuery document.createElement equivalent?

For GitExtension users:
I faced the same issue after upgrading git to 2.19.0
Solution:
Tools > Settings > Git Extensions > SSH
Select [OpenSSH] instead of [PuTTY]
u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)
Using the path /inout-tracker
without a trailing /
doesn't fetch index.php
. Instead the server will issue a 302
redirect to the version with the trailing /
.
Doing a 302 will typically cause clients to convert a POST to a GET request.
Programmatic ICMP ping is complicated due to the elevated privileges required to send raw ICMP packets, and calling ping
binary is ugly. For server monitoring, you can achieve the same result using a technique called TCP ping:
# pip3 install tcping
>>> from tcping import Ping
# Ping(host, port, timeout)
>>> ping = Ping('212.69.63.54', 22, 60)
>>> ping.ping(3)
Connected to 212.69.63.54[:22]: seq=1 time=23.71 ms
Connected to 212.69.63.54[:22]: seq=2 time=24.38 ms
Connected to 212.69.63.54[:22]: seq=3 time=24.00 ms
Internally, this simply establishes a TCP connection to the target server and drops it immediately, measuring time elapsed. This particular implementation is a bit limited in that it doesn't handle closed ports but for your own servers it works pretty well.
You can create a character array that does this via a loop:
>> for i=1:10 Names(i,:)='Sample Text'; end >> Names Names = Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text
However, this would be better implemented using REPMAT:
>> Names = repmat('Sample Text', 10, 1) Names = Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text
all the above did not work when i used cloudflare, this one worked for me:
RewriteCond %{HTTP:X-Forwarded-Proto} =https
RewriteRule ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
and this one definitely works without proxies in the way:
RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

When representing the m-dash in a JavaScript text string for output to HTML, note that it will be represented by its unicode value. There are cases when ampersand characters ('&') will not be resolved—notably certain contexts within JSX. In this case, neither —
nor —
will work. Instead you need to use the Unicode escape sequence: \u2014
.
For example, when implementing a render()
method to output text from a JavaScript variable:
render() {
let text='JSX transcoders will preserve the & character—to '
+ 'protect from possible script hacking and cross-site hacks.'
return (
<div>{text}</div>
)
}
This will output:
<div>JSX transcoders will preserve the & character—to protect from possible script hacking and cross-site hacks.</div>
Instead of the &
– prefixed representation, you should use \u2014:
let text='JSX transcoders will preserve the & character\u2014to …'
I use
<div th:text ="${variable != null} ? (${variable != ''} ? ${variable} : 'empty string message') : 'null message' "></div>
If array elements don't contain spaces, another (perhaps more readable) solution would be:
if echo ${arr[@]} | grep -q -w "d"; then
echo "is in array"
else
echo "is not in array"

For reference and adding to answers citing mefa, it might worth to take a look on the implementation of mefa::rep.data.frame()

Use application/javascript
as content type instead of text/javascript
text/javascript
is mentioned obsolete. See reference docs.
http://www.iana.org/assignments/media-types/application
Also see this question on SO.
UPDATE:
I have tried executing the code you have given and the below didn't work.
res.setHeader('content-type', 'text/javascript');
res.send(JS_Script);
This is what worked for me.
res.setHeader('content-type', 'text/javascript');
res.end(JS_Script);
As robertklep has suggested, please refer to the node http docs, there is no response.send()
there.
You can also add labels that are tied to your radio buttons with the same ID, which then allows the user to click the radio button or label to select that item. I'm using constants here for "Male", "Female" and "Unknown", but obviously these could be strings in your model.
<%: Html.RadioButtonFor(m => m.Gender, "Male",
new Dictionary<string, object> { { "checked", "checked" }, { "id", "Male" } }) %>
<%: Html.Label("Male") %>
<%: Html.RadioButtonFor(m => m.Gender, "Female",
new Dictionary<string, object> { { "id", "Female" } }) %>
<%: Html.Label("Female")%>
<%: Html.RadioButtonFor(m => m.Gender, "Unknown",
new Dictionary<string, object> { { "id", "Unknown" } }) %>
<%: Html.Label("Unknown")%>
You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close()
method:
>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor
The line del f
deletes the last reference to the file object, causing its destructor file.__del__
to be called. The internal state of the file object indicates the file is still open since f.close()
was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.
Since the implementation of os.system()
does not create any Python file objects, it does not seem likely that the system()
call is the origin of the error. Maybe you could show a bit more code?
If the object is actually a Boolean
instance, then just cast it:
boolean di = (Boolean) someObject;
The explicit cast will do the conversion to Boolean
, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:
boolean di = ((Boolean) someObject).booleanValue();
If someObject
doesn't refer to a Boolean value though, what do you want the code to do?
Flutter is designed to use the latest Android version installed. So if you have an incomplete download of the latest Android, Flutter will try to use that.
So either complete the installation or delete the complete installation. You can find the Android versions at: /home/{user}/Android/Sdk/platforms/android-29/android.jar
In MySQL, @variable
indicates a user-defined variable. You can define your own.
SET @a = 'test';
SELECT @a;
Outside of stored programs, a variable
, without @
, is a system variable, which you cannot define yourself.
The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.
This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.
The popular answer here does work sometimes, but other times it creates horizontal scroll bars that are tough to deal with - especially when dealing with wide horizontal navigations and large pull down menus. Here is an even lighter-weight version that helps avoid those edge cases:
#wrap {
float: right;
position: relative;
left: -50%;
}
#content {
left: 50%;
position: relative;
}
To more specifically answer your question, it is probably not possible to do without setting up some containing element, however it is very possible to do without specifying a width value. Hope that saves someone out there some headaches!
You can have it in the xml.
<android.support.design.widget.TabLayout

Just do one thing, We need to set the name property for the same types. for eg.
Try below:
<form>
<div id="group1">
<input type="radio" value="val1" name="group1">
<input type="radio" value="val2" name="group1">
</div>
</form>
And also we can do it in angular1,angular 2 or in jquery also.
<div *ngFor="let option of question.options; index as j">
<input type="radio" name="option{{j}}" value="option{{j}}" (click)="checkAnswer(j+1)">{{option}}
</div>
It looks like you are trying to do this?
Iterate and mutate an array using Array.prototype.splice
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'b', 'c', 'b', 'a'];
review.forEach(function(item, index, object) {
if (item === 'a') {
object.splice(index, 1);
}
});
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Which works fine for simple case where you do not have 2 of the same values as adjacent array items, other wise you have this problem.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
review.forEach(function(item, index, object) {
if (item === 'a') {
object.splice(index, 1);
}
});
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
So what can we do about this problem when iterating and mutating an array? Well the usual solution is to work in reverse. Using ES3 while but you could use for sugar if preferred
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a' ,'a', 'b', 'c', 'b', 'a', 'a'],
index = review.length - 1;
while (index >= 0) {
if (review[index] === 'a') {
review.splice(index, 1);
}
index -= 1;
}
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Ok, but you wanted to use ES5 iteration methods. Well and option would be to use Array.prototype.filter but this does not mutate the original array but creates a new one, so while you can get the correct answer it is not what you appear to have specified.
We could also use ES5 Array.prototype.reduceRight, not for its reducing property by rather its iteration property, i.e. iterate in reverse.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
review.reduceRight(function(acc, item, index, object) {
if (item === 'a') {
object.splice(index, 1);
}
}, []);
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Or we could use ES5 Array.protoype.indexOf like so.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'],
index = review.indexOf('a');
while (index !== -1) {
review.splice(index, 1);
index = review.indexOf('a');
}
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
But you specifically want to use ES5 Array.prototype.forEach, so what can we do? Well we need to use Array.prototype.slice to make a shallow copy of the array and Array.prototype.reverse so we can work in reverse to mutate the original array.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
review.slice().reverse().forEach(function(item, index, object) {
if (item === 'a') {
review.splice(object.length - 1 - index, 1);
}
});
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Finally ES6 offers us some further alternatives, where we do not need to make shallow copies and reverse them. Notably we can use Generators and Iterators. However support is fairly low at present.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
function* reverseKeys(arr) {
var key = arr.length - 1;
while (key >= 0) {
yield key;
key -= 1;
}
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
for (var index of reverseKeys(review)) {
if (review[index] === 'a') {
review.splice(index, 1);
}
}
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Something to note in all of the above is that, if you were stripping NaN from the array then comparing with equals is not going to work because in Javascript NaN === NaN
is false. But we are going to ignore that in the solutions as it it yet another unspecified edge case.
So there we have it, a more complete answer with solutions that still have edge cases. The very first code example is still correct but as stated, it is not without issues.
Use LINQ Aggregate
method to convert array of integers to a comma separated string
var intArray = new []{1,2,3,4};
string concatedString = intArray.Aggregate((a, b) =>Convert.ToString(a) + "," +Convert.ToString( b));
Response.Write(concatedString);
output will be
1,2,3,4
This is one of the solution you can use if you have not .net 4 installed.
If you code your x axis text categories, list them in a single column, then in adjacent columns list plot points for respective variables against relevant text category code and just leave blank cells against non-relevant text category code, you can scatter plot and get the displayed result. Any questions let me know.
When using nohup
and you put the task in the background, the background operator (&
) will give you the PID at the command prompt. If your plan is to manually manage the process, you can save that PID and use it later to kill the process if needed, via kill PID
or kill -9 PID
(if you need to force kill). Alternatively, you can find the PID later on by ps -ef | grep "command name"
and locate the PID from there. Note that nohup
keyword/command itself does not appear in the ps
output for the command in question.
If you use a script, you could do something like this in the script:
nohup my_command > my.log 2>&1 &
echo $! > save_pid.txt
This will run my_command
saving all output into my.log
(in a script, $!
represents the PID of the last process executed). The 2
is the file descriptor for standard error (stderr
) and 2>&1
tells the shell to route standard error output to the standard output (file descriptor 1
). It requires &1
so that the shell knows it's a file descriptor in that context instead of just a file named 1
. The 2>&1
is needed to capture any error messages that normally are written to standard error into our my.log
file (which is coming from standard output). See I/O Redirection for more details on handling I/O redirection with the shell.
If the command sends output on a regular basis, you can check the output occasionally with tail my.log
, or if you want to follow it "live" you can use tail -f my.log
. Finally, if you need to kill the process, you can do it via:
kill -9 `cat save_pid.txt`
rm save_pid.txt
The options for popen
can be used in call
args,
bufsize=0,
executable=None,
stdin=None,
stdout=None,
stderr=None,
preexec_fn=None,
close_fds=False,
shell=False,
cwd=None,
env=None,
universal_newlines=False,
startupinfo=None,
creationflags=0
So...
subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], stdout=myoutput)
Then you can do what you want with myoutput
(which would need to be a file btw).
Also, you can do something closer to a piped output like this.
dmesg | grep hda
would be:
p1 = Popen(["dmesg"], stdout=PIPE)
p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]
There's plenty of lovely, useful info on the python manual page.
Assume we have a function sort(int *arraytobesorted,void (*algorithmchosen)(void))
where it can accept a function pointer as its argument which can be used at some point in sort()
's implementation . Then , here the code that is being addressed by the function pointer algorithmchosen
is called as callback function .
And see the advantage is that we can choose any algorithm like:
1. algorithmchosen = bubblesort
2. algorithmchosen = heapsort
3. algorithmchosen = mergesort ...
Which were, say,have been implemented with the prototype:
1. `void bubblesort(void)`
2. `void heapsort(void)`
3. `void mergesort(void)` ...

You set the size on initialization:
fig2 = matplotlib.pyplot.figure(figsize=(8.0, 5.0)) # in inches!
Edit:
If the problem is with x-axis ticks - You can set them "manually":
fig2.add_subplot(111).set_xticks(arange(1,3,0.5)) # You can actually compute the interval You need - and substitute here
And so on with other aspects of Your plot. You can configure it all. Here's an example:
from numpy import arange
import matplotlib
# import matplotlib as mpl
import matplotlib.pyplot
# import matplotlib.pyplot as plt
x1 = [1,2,3]
y1 = [4,5,6]
x2 = [1,2,3]
y2 = [5,5,5]
# initialization
fig2 = matplotlib.pyplot.figure(figsize=(8.0, 5.0)) # The size of the figure is specified as (width, height) in inches
# lines:
l1 = fig2.add_subplot(111).plot(x1,y1, label=r"Text $formula$", "r-", lw=2)
l2 = fig2.add_subplot(111).plot(x2,y2, label=r"$legend2$" ,"g--", lw=3)
fig2.add_subplot(111).legend((l1,l2), loc=0)
# axes:
fig2.add_subplot(111).grid(True)
fig2.add_subplot(111).set_xticks(arange(1,3,0.5))
fig2.add_subplot(111).axis(xmin=3, xmax=6) # there're also ymin, ymax
fig2.add_subplot(111).axis([0,4,3,6]) # all!
fig2.add_subplot(111).set_xlim([0,4])
fig2.add_subplot(111).set_ylim([3,6])
# labels:
fig2.add_subplot(111).set_xlabel(r"x $2^2$", fontsize=15, color = "r")
fig2.add_subplot(111).set_ylabel(r"y $2^2$")
fig2.add_subplot(111).set_title(r"title $6^4$")
fig2.add_subplot(111).text(2, 5.5, r"an equation: $E=mc^2$", fontsize=15, color = "y")
fig2.add_subplot(111).text(3, 2, unicode('f\374r', 'latin-1'))
# saving:
fig2.savefig("fig2.png")
So - what exactly do You want to be configured?
Simplest I could come up...
function resizeResizeableHeight() {
$('.resizableHeight').each( function() {
$(this).outerHeight( $(this).parent().height() - ( $(this).offset().top - ( $(this).parent().offset().top + parseInt( $(this).parent().css('padding-top') ) ) ) )
});
}
Now all you have to do is add the resizableHeight class to everything you want to autosize (to it's parent).
If you are using a linux system you can get a random number out of /dev/random or /dev/urandom. Be carefull /dev/random will block if there are not enough random numbers available. If you need speed over randomness use /dev/urandom.
These "files" will be filled with random numbers generated by the operating system. It depends on the implementation of /dev/random on your system if you get true or pseudo random numbers. True random numbers are generated with help form noise gathered from device drivers like mouse, hard drive, network.
You can get random numbers from the file with dd
I'm not sure if this is fully answering the question (it isn't), but it's the solution I came up with for my very similar problem. I know some of the other solutions look shorter but they seem to use SUBSTRING_INDEX() way more than necessary. Here I try to just use LOCATE() just once per delimiter.

DROP FUNCTION IF EXISTS test_PVreplace;
delimiter //
CREATE FUNCTION test_PVreplace (
str TEXT, -- String to do search'n'replace on
pv TEXT -- Parameter/value pairs 'p1=v1|p2=v2|p3=v3'
)
RETURNS TEXT
-- Replace specific tags with specific values.
sproc:BEGIN
DECLARE idx INT;
DECLARE idx0 INT DEFAULT 1; -- 1-origined, not 0-origined
DECLARE len INT;
DECLARE sPV TEXT;
DECLARE iPV INT;
DECLARE sP TEXT;
DECLARE sV TEXT;
-- P/V string *must* end with a delimiter.
IF (RIGHT (pv, 1) <> '|') THEN
SET pv = CONCAT (pv, '|');
END IF;
-- Find all the P/V pairs.
SELECT LOCATE ('|', pv, idx0) INTO idx;
WHILE (idx > 0) DO
SET len = idx - idx0;
SELECT SUBSTRING(pv, idx0, len) INTO sPV;
-- Found a P/V pair. Break it up.
SELECT LOCATE ('=', sPV) INTO iPV;
IF (iPV = 0) THEN
SET sP = sPV;
SET sV = '';
ELSE
SELECT SUBSTRING(sPV, 1, iPV-1) INTO sP;
SELECT SUBSTRING(sPV, iPV+1) INTO sV;
END IF;
-- Do the substitution(s).
SELECT REPLACE (str, sP, sV) INTO str;
-- Do next P/V pair.
SET idx0 = idx + 1;
SELECT LOCATE ('|', pv, idx0) INTO idx;
END WHILE;
RETURN (str);
END//

When binding the UI to your array you'll want to make sure you update that same array directly by setting the length to 0 and pushing the data into the array.
Instead of this (which set a different array reference to data
which your UI won't know about):
myService.async = function() {
$http.get('test.json')
.success(function (d) {
data = d;
});
};
try this:
myService.async = function() {
$http.get('test.json')
.success(function (d) {
data.length = 0;
for(var i = 0; i < d.length; i++){
data.push(d[i]);
}
});
};
Here is a fiddle that shows the difference between setting a new array vs emptying and adding to an existing one. I couldn't get your plnkr working but hopefully this works for you!
RFC 2616, section 14.9.1:
Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.
Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.
For me, a more concrete example of Cache-Control: private
is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.
FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.
This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.
Workaround....
In VS 2015 Professional (and probably other versions). Go to Tools / Options / Environment / Fonts and Colours. In the "Show Settings For" drop-down, select "CodeLens" Choose the smallest font you can find e.g. Calibri 6. Change the foreground colour to your editor foreground colour (say "White") Click OK.
The following snippet will safely create a temporary directory (-d
) and store its name into the TMPDIR
. (An example use of TMPDIR
variable is shown later in the code where it's used for storing original files that will be possibly modified.)
The first trap
line executes exit 1
command when any of the specified signals is received. The second trap
line removes (cleans up) the $TMPDIR
on program's exit (both normal and abnormal). We initialize these traps after we check that mkdir -d
succeeded to avoid accidentally executing the exit trap with $TMPDIR
in an unknown state.
#!/bin/bash
# Create a temporary directory and store its name in a variable ...
TMPDIR=$(mktemp -d)
# Bail out if the temp directory wasn't created successfully.
if [ ! -e $TMPDIR ]; then
>&2 echo "Failed to create temp directory"
exit 1
fi
# Make sure it gets removed even if the script exits abnormally.
trap "exit 1" HUP INT PIPE QUIT TERM
trap 'rm -rf "$TMPDIR"' EXIT
# Example use of TMPDIR:
for f in *.csv; do
cp "$f" "$TMPDIR"
# remove duplicate lines but keep order
perl -ne 'print if ++$k{$_}==1' "$TMPDIR/$f" > "$f"
done
Using 'javascript:void 0' will do cause problem in IE
when you click the link, it will trigger onbeforeunload event of window !
<!doctype html>
<html>
<head>
</head>
<body>
<a href="javascript:void(0);" >Click me!</a>
<script>
window.onbeforeunload = function() {
alert( 'oops!' );
};
</script>
</body>
</html>
You can indicate the new process should be started with elevated permissions by setting the Verb property of your startInfo object to 'runas', as follows:
startInfo.Verb = "runas";
This will cause Windows to behave as if the process has been started from Explorer with the "Run as Administrator" menu command.
This does mean the UAC prompt will come up and will need to be acknowledged by the user: if this is undesirable (for example because it would happen in the middle of a lengthy process), you'll need to run your entire host process with elevated permissions by Create and Embed an Application Manifest (UAC) to require the 'highestAvailable' execution level: this will cause the UAC prompt to appear as soon as your app is started, and cause all child processes to run with elevated permissions without additional prompting.
Edit: I see you just edited your question to state that "runas" didn't work for you. That's really strange, as it should (and does for me in several production apps). Requiring the parent process to run with elevated rights by embedding the manifest should definitely work, though.
