I added this
TEMPLATE_DIRS = (
os.path.join(SETTINGS_PATH, 'templates'),
)
and it still showed the error, then I realized that in another project the templates was showing without adding that code in settings.py file so I checked that project and I realized that I didn't create a virtual environment in this project so I did
virtualenv env
and it worked, don't know why
Can get ID before add documents in database:
var idBefore = this.afs.createId();
console.log(idBefore);
Add an onchange event handler and set the pages location to the value
<select id="foo">
<option value="">Pick a site</option>
<option value="http://www.google.com">x</option>
<option value="http://www.yahoo.com">y</option>
</select>
<script>
document.getElementById("foo").onchange = function() {
if (this.selectedIndex!==0) {
window.location.href = this.value;
}
};
</script>
@Frode F. gave the right answer.
By the Way Invoke-WebRequest
also prints you the 200 OK
and a lot of bla, bla, bla... which might be useful but I still prefer the Invoke-RestMethod
which is lighter.
Also, keep in mind that you need to use | ConvertTo-Json
for the body only, not the header:
$body = @{
"UserSessionId"="12345678"
"OptionalEmail"="[email protected]"
} | ConvertTo-Json
$header = @{
"Accept"="application/json"
"connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
"Content-Type"="application/json"
}
Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML
and you can then append a | ConvertTo-HTML
at the end of the request for better readability
You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else.
By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment
in order to find the action.
I'd prefer not to use an HTML5 only element such as <section>
. Also grouping the input fields might painful if you try to generate the form with code. It's always better to produce similar markup for each one and only change the class names. Therefore I would recommend a solution that looks like this :
CSS
label, input {
display: block;
}
ul.form {
width : 500px;
padding: 0px;
margin : 0px;
list-style-type: none;
}
ul.form li {
width : 500px;
}
ul.form li input {
width : 200px;
}
ul.form li textarea {
width : 450px;
height: 150px;
}
ul.form li.twoColumnPart {
float : left;
width : 250px;
}
HTML
<form name="message" method="post">
<ul class="form">
<li class="twoColumnPart">
<label for="name">Name</label>
<input id="name" type="text" value="" name="name">
</li>
<li class="twoColumnPart">
<label for="email">Email</label>
<input id="email" type="text" value="" name="email">
</li>
<li>
<label for="subject">Subject</label>
<input id="subject" type="text" value="" name="subject">
</li>
<li>
<label for="message">Message</label>
<textarea id="message" type="text" name="message"></textarea>
</li>
</ul>
</form>
Try
use an id
for hidden field and use id of checkbox
in javascript.
and change the ClientIDMode="static"
too
<input type="hidden" ClientIDMode="static" id="label1" name="label206451" value="0" />
<script type="text/javascript">
var cb = document.getElementById('txt206451');
var label = document.getElementById('label1');
cb.addEventListener('click',function(evt){
if(cb.checked){
label.value='Thanks'
}else{
label.value='0'
}
},false);
</script>
The right way to install grunt is by running this command:
npm install grunt -g
(Prepend "sudo" to the command above if you get a EACCESS error message)
-g will make npm install the package globally, so you will be able to use it whenever you want in your current machine.
You can create the path if it doesn't exist yet with a method like the following:
using System.IO;
private void CreateIfMissing(string path)
{
bool folderExists = Directory.Exists(Server.MapPath(path));
if (!folderExists)
Directory.CreateDirectory(Server.MapPath(path));
}
I've had to do something similar on a CI system recently. My options were to do it entirely in bash (yikes) or use a language like python which would have made programming the logic much simpler.
My workaround was to do the programming in python and write the results to a file. Then use bash to export the results.
For example:
# do calculations in python
with open("./my_export", "w") as f:
f.write(your_results)
# then in bash
export MY_DATA="$(cat ./my_export)"
rm ./my_export # if no longer needed
Because strip()
only strips trailing and leading characters, based on what you provided. I suggest:
>>> import re
>>> name = "Barack (of Washington)"
>>> name = re.sub('[\(\)\{\}<>]', '', name)
>>> print(name)
Barack of Washington
I added a class to easily implement menu arguments. So you can customize and include in your function like this:
include_once get_template_directory() . DIRECTORY_SEPARATOR . "your-directory" . DIRECTORY_SEPARATOR . "Menu.php";
<?php $menu = (new Menu('your-theme-location'))
->setMenuClass('your-menu')
->setMenuID('your-menu-id')
->setListClass('your-menu-class')
->setLinkClass('your-menu-link anchor') ?>
// Print your menu
<?php $menu->showMenu() ?>
<?php
class Menu
{
private $args = [
'theme_location' => '',
'container' => '',
'menu_id' => '',
'menu_class' => '',
'add_li_class' => '',
'link_class' => ''
];
public function __construct($themeLocation)
{
add_filter('nav_menu_css_class', [$this,'add_additional_class_on_li'], 1, 3);
add_filter( 'nav_menu_link_attributes', [$this,'add_menu_link_class'], 1, 3 );
$this->args['theme_location'] = $themeLocation;
}
public function wrapWithTag($tagName){
$this->args['container'] = $tagName;
return $this;
}
public function setMenuID($id)
{
$this->args['menu_id'] = $id;
return $this;
}
public function setMenuClass($class)
{
$this->args['menu_class'] = $class;
return $this;
}
public function setListClass($class)
{
$this->args['add_li_class'] = $class;
return $this;
}
public function setLinkClass($class)
{
$this->args['link_class'] = $class;
return $this;
}
public function showMenu()
{
return wp_nav_menu($this->args);
}
function add_additional_class_on_li($classes, $item, $args) {
if(isset($args->add_li_class)) {
$classes[] = $args->add_li_class;
}
return $classes;
}
function add_menu_link_class( $atts, $item, $args ) {
if (property_exists($args, 'link_class')) {
$atts['class'] = $args->link_class;
}
return $atts;
}
}
You can use .filter
on a jQuery object that was created from the response:
success: function(data){
//Create jQuery object from the response HTML.
var $response=$(data);
//Query the jQuery object for the values
var oneval = $response.filter('#one').text();
var subval = $response.filter('#sub').text();
}
The "if" expression tests for truthiness, while the double-equal tests for type-independent equivalency. A string is always truthy, as others here have pointed out. If the double-equal were testing both of its operands for truthiness and then comparing the results, then you'd get the outcome you were intuitively assuming, i.e. ("0" == true) === true
. As Doug Crockford says in his excellent JavaScript: the Good Parts, "the rules by which [== coerces the types of its operands] are complicated and unmemorable.... The lack of transitivity is alarming." It suffices to say that one of the operands is type-coerced to match the other, and that "0" ends up being interpreted as a numeric zero, which is in turn equivalent to false when coerced to boolean (or false is equivalent to zero when coerced to a number).
Select select = new Select(_element);
List<WebElement> selectedOptions = select.getAllSelectedOptions();
if(selectedOptions.size() > 0){
return true;
}else{
return false;
}
To create a label for text:
JLabel label1 = new JLabel("Test");
To change the text in the label:
label1.setText("Label Text");
And finally to clear the label:
label1.setText("");
And all you have to do is place the label in your layout, or whatever layout system you are using, and then just add it to the JFrame...
IE can set username and password proxies, so maybe setting it there and import does work
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d name:port
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyUser /t REG_SZ /d username
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyPass /t REG_SZ /d password
netsh winhttp import proxy source=ie
Syntax: (Triple dot ... ) --> Means we can add zero or more objects pass in an arguments or pass an array of type object.
public static void main(String[] args){}
public static void main(String... args){}
Definition: 1) The Object ... argument is just a reference to an array of Objects.
2) ('String []' or String ... ) It can able to handle any number of string objects. Internally it uses an array of reference type object.
i.e. Suppose we pass an Object array to the ... argument - will the resultant argument value be a two-dimensional array - because an Object[] is itself an Object:
3) If you want to call the method with a single argument and it happens to be an array, you have to explicitly wrap it in
another. method(new Object[]{array});
OR
method((Object)array), which will auto-wrap.
Application: It majorly used when the number of arguments is dynamic(number of arguments know at runtime) and in overriding. General rule - In the method we can pass any types and any number of arguments. We can not add object(...) arguments before any specific arguments. i.e.
void m1(String ..., String s) this is a wrong approach give syntax error.
void m1(String s, String ...); This is a right approach. Must always give last order prefernces.
I thought it would be valuable to summarize and compare the given answers.
(easier/shorter/memorable option)
[Environment]::UserName
-- @ThomasBratt$env:username
-- @Eoinwhoami
-- @galaktor(more dependable option)
[System.Security.Principal.WindowsIdentity]::GetCurrent().Name
-- @MarkSeemann(rather than the name of the user running the PowerShell instance)
$(Get-WMIObject -class Win32_ComputerSystem | select username).username
-- @TwonOfAn on this other forum@Kevin Panko's comment on @Mark Seemann's answer deals with choosing one of the categories over the other:
[The Windows access token approach] is the most secure answer, because $env:USERNAME can be altered by the user, but this will not be fooled by doing that.
In short, the environment variable option is more succinct, and the Windows access token option is more dependable.
I've had to use @Mark Seemann's Windows access token approach in a PowerShell script that I was running from a C# application with impersonation.
The C# application is run with my user account, and it runs the PowerShell script as a service account. Because of a limitation of the way I'm running the PowerShell script from C#, the PowerShell instance uses my user account's environment variables, even though it is run as the service account user.
In this setup, the environment variable options return my account name, and the Windows access token option returns the service account name (which is what I wanted), and the logged in user option returns my account name.
Also, if you want to compare the options yourself, here is a script you can use to run a script as another user. You need to use the Get-Credential cmdlet to get a credential object, and then run this script with the script to run as another user as argument 1, and the credential object as argument 2.
Usage:
$cred = Get-Credential UserTo.RunAs
Run-AsUser.ps1 "whoami; pause" $cred
Run-AsUser.ps1 "[System.Security.Principal.WindowsIdentity]::GetCurrent().Name; pause" $cred
Contents of Run-AsUser.ps1 script:
param(
[Parameter(Mandatory=$true)]
[string]$script,
[Parameter(Mandatory=$true)]
[System.Management.Automation.PsCredential]$cred
)
Start-Process -Credential $cred -FilePath 'powershell.exe' -ArgumentList 'noprofile','-Command',"$script"
You can directly set the content type like below:
res.writeHead(200, {'Content-Type': 'text/plain'});
For reference go through the nodejs Docs link.
Note that this will not work:
header('Location: $url');
You need to do this (for variable expansion):
header("Location: $url");
You tend to handle number of arguments with this sort of logic:
IF "%1"=="" GOTO HAVE_0
IF "%2"=="" GOTO HAVE_1
IF "%3"=="" GOTO HAVE_2
etc.
If you have more than 9 arguments then you are screwed with this approach though. There are various hacks for creating counters which you can find here, but be warned these are not for the faint hearted.
It's true, minimal-ui
could be both useful and harmful, and I suppose the trade-off now has another balance, in favor of newer, bigger iPhones.
I've been dealing with the issue while working with my js framework for HTML5 apps. After many attempted solutions, each with their drawbacks, I surrendered to considering that space lost on iPhones previous than 6. Given the situation, I think that the only solid and predictable behavior is a pre-determined one.
In short, I ended up preventing any form of minimal-ui, so at least my screen height is always the same and you always know what actual space you have for your app.
With the help of time, enough users will have more room.
EDIT
This is a little simplified, for demo purpose, but should work for you. Assuming you have a main container
html, body, #main {
height: 100%;
width: 100%;
overflow: hidden;
}
.view {
width: 100%;
height: 100%;
overflow: scroll;
}
Then:
then with js, I set #main
's height to the window's available height. This also helps dealing with other scrolling bugs found in both iOS and Android. It also means that you need to deal on how to update it, just note that;
I block over-scrolling when reaching the boundaries of the scroll. This one is a bit more deep in my code, but I think you can as well follow the principle of this answer for basic functionality. I think it could flickr a little, but will do the job.
As a sidenote: this app too is bookmarkable, as it uses an internal routing to hashed addresses, but I also added a prompt iOS users to add to home. I feel this way helps loyalty and returning visitors (and so the lost space is back).
Use System.Math.Round to rounds a decimal value to a specified number of fractional digits.
var pay = 200 + bonus;
pay = System.Math.Round(pay, 2);
Console.WriteLine(pay);

You can also get the same error if the Java DB server has not been started.
Very good question. The Java Language specification confirms your suggestion.
For example, the following code is correct:
short x = 3; x += 4.6;
and results in x having the value 7 because it is equivalent to:
short x = 3; x = (short)(x + 4.6);
That also resolved my issue.
@ViewChild('map', {static: false}) googleMap;
Although Pascal MARTIN is correct that PDO doesn't send the complete query to the database all at once, ryeguy's suggestion to use the DB's logging function actually allowed me to see the complete query as assembled and executed by the database.
Here's how: (These instructions are for MySQL on a Windows machine - your mileage may vary)
my.ini
, under the [mysqld]
section, add a log
command, like log="C:\Program Files\MySQL\MySQL Server 5.1\data\mysql.log"
That file will grow quickly, so be sure to delete it and turn off logging when you're done testing.
In your .m file, declare a file global variable:
static int currentID = 1;
then in your init routine, refernce that:
- (id) init
{
self = [super init];
if (self != nil) {
_myID = currentID++; // not thread safe
}
return self;
}
or if it needs to change at some other time (eg in your openConnection method), then increment it there. Remember it is not thread safe as is, you'll need to do syncronization (or better yet, use an atomic add) if there may be any threading issues.
I have created a patch for the issue. Simply I am checking if the browser does support localStorage or sessionStorage or not. If not then the storage engine will be Cookie. But the negative side is Cookie have very tiny storage memory :(
function StorageEngine(engine) {
this.engine = engine || 'localStorage';
if(!this.checkStorageApi(this.engine)) {
// Default engine would be alway cooke
// Safari private browsing issue with localStorage / sessionStorage
this.engine = 'cookie';
}
}
StorageEngine.prototype.checkStorageApi = function(name) {
if(!window[name]) return false;
try {
var tempKey = '__temp_'+Date.now();
window[name].setItem(tempKey, 'hi')
window[name].removeItem(tempKey);
return true;
} catch(e) {
return false;
}
}
StorageEngine.prototype.getItem = function(key) {
if(['sessionStorage', 'localStorage'].includes(this.engine)) {
return window[this.engine].getItem(key);
} else if('cookie') {
var name = key+"=";
var allCookie = decodeURIComponent(document.cookie).split(';');
var cval = [];
for(var i=0; i < allCookie.length; i++) {
if (allCookie[i].trim().indexOf(name) == 0) {
cval = allCookie[i].trim().split("=");
}
}
return (cval.length > 0) ? cval[1] : null;
}
return null;
}
StorageEngine.prototype.setItem = function(key, val, exdays) {
if(['sessionStorage', 'localStorage'].includes(this.engine)) {
window[this.engine].setItem(key, val);
} else if('cookie') {
var d = new Date();
var exdays = exdays || 1;
d.setTime(d.getTime() + (exdays*24*36E5));
var expires = "expires="+ d.toUTCString();
document.cookie = key + "=" + val + ";" + expires + ";path=/";
}
return true;
}
// ------------------------
var StorageEngine = new StorageEngine(); // new StorageEngine('localStorage');
// If your current browser (IOS safary or any) does not support localStorage/sessionStorage, then the default engine will be "cookie"
StorageEngine.setItem('keyName', 'val')
var expireDay = 1; // for cookie only
StorageEngine.setItem('keyName', 'val', expireDay)
StorageEngine.getItem('keyName')
It's the last selected DOM node index. Chrome assigns an index to each DOM node you select. So $0
will always point to the last node you selected, while $1
will point to the node you selected before that. Think of it like a stack of most recently selected nodes.
As an example, consider the following
<div id="sunday"></div>
<div id="monday"></div>
<div id="tuesday"></div>
Now you opened the devtools console and selected #sunday
, #monday
and #tuesday
in the mentioned order, you will get ids like:
$0 -> <div id="tuesday"></div>
$1 -> <div id="monday"></div>
$2 -> <div id="sunday"></div>
Note: It Might be useful to know that the node is selectable in your scripts (or console), for example one popular use for this is angular element selector, so you can simply pick your node, and run this:
angular.element($0).scope()
Voila you got access to node scope via console.
If you plan to create a PHP package you most likely want to put in on Packagist to make it available for other with composer.
Composer has the as naming-convention to use vendorname/package-name-is-lowercase-with-hyphens
.
If you plan to create a JS package you probably want to use npm. One of their naming conventions is to not permit upper case letters in the middle of your package name.
Therefore, I would recommend for PHP and JS packages to use lowercase-with-hyphens
and name your packages in composer or npm identically to your package on GitHub.
There's always the chr() function, which converts an ascii code to string.
ie. something like: INSERT INTO table VALUES ( CONCAT( 'J', CHR(38), 'J' ) )
You cannot (should not?) define anything as undefined, as the variable would no longer be undefined – you just defined it to something.
You cannot (should not?) pass undefined
to a function. If you want to pass an empty value, use null
instead.
The statement if(!testvar)
checks for boolean true/false values, this particular one tests whether testvar
evaluates to false
. By definition, null
and undefined
shouldn't be evaluated neither as true
or false
, but JavaScript evaluates null
as false
, and gives an error if you try to evaluate an undefined variable.
To properly test for undefined
or null
, use these:
if(typeof(testvar) === "undefined") { ... }
if(testvar === null) { ... }
Your find should look like that to avoid sending directory names to sed:
find ./ -type f -exec sed -i -e 's/apple/orange/g' {} \;
Adding following property to your persistence.xml may solve your problem temporarily
<property name="hibernate.enable_lazy_load_no_trans" value="true" />
As @vlad-mihalcea said it's an antipattern and does not solve lazy initialization issue completely, initialize your associations before closing transaction and use DTOs instead.

About the server can deliver to the clients the root cert or not, extracted from the RFC-5246 'The Transport Layer Security (TLS) Protocol Version 1.2' doc it says:
certificate_list
This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it. Because certificate validation requires that root keys be distributed independently, the self-signed certificate that specifies the root certificate authority MAY be omitted from the chain, under the
assumption that the remote end must already possess it in order to validate it in any case.
About the term 'MAY', extracted from the RFC-2119 "Best Current Practice" says:
5.MAY
This word, or the adjective "OPTIONAL", mean that an item is truly optional. One vendor may choose to include the item because a
particular marketplace requires it or because the vendor feels that
it enhances the product while another vendor may omit the same item.
An implementation which does not include a particular option MUST be
prepared to interoperate with another implementation which does
include the option, though perhaps with reduced functionality. In the same vein an implementation which does include a particular option
MUST be prepared to interoperate with another implementation which
does not include the option (except, of course, for the feature the
option provides.)
In conclusion, the root may be at the certification path delivered by the server in the handshake.
A practical use.
Think about, not in navigator user terms, but on a transfer tool at a server in a militarized zone with limited internet access.
The server, playing the client role at the transfer, receives all the certs path from the server.
All the certs in the chain should be checked to be trusted, root included.
The only way to check this is the root be included at the certs path in transfer time, being matched against a previously declared as 'trusted' local copy of them.

Divide and Conquer involves three steps at each level of recursion:
Dynamic Programming involves the following four steps:
1. Characterise the structure of optimal solutions.
2. Recursively define the values of optimal solutions.
3. Compute the value of optimal solutions.
4. Construct an Optimal Solution from computed information.
For easier understanding, lets see divide and conquer as a brute force solution and its optimisation as dynamic programming.
N.B. divide and conquer algorithms with overlapping subproblems can only be optimised with dp.

The problem is that Hive

Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.
In WSDL types element looks as follows:
<types>
<xsd:schema>
<xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
</xsd:schema>
</types>
The schema is importing from external reference.
RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.
<types/>
<message name="getHelloWorldAsString">
<part name="arg0" type="xsd:string"/>
</message>
<message name="getHelloWorldAsStringResponse">
<part name="return" type="xsd:string"/>
</message>
RPC : No types in WSDL
Document: Types section would be available in WSDL
e.g. you're using php and $filepath contains pdf file path.
so you can write javascript like to to emulate download dialog box.
<script language="javascript">
window.location.href = '<?php echo $filepath; ?>';
</script
Above code sends browser to pdf file by its url "http://www.domain.com/files/filename.pdf". So at last, browser will show download dialog box to where to save this file on your machine.
You will have to hand code it, SQL Profiler reveals the following.
SMSE executes quite a long string of queries when it generates the statement.
The following query (or something along its lines) is used to extract the text:
SELECT
NULL AS [Text],
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]
FROM
sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE
(sp.type = N'P' OR sp.type = N'RF' OR sp.type='PC')and(sp.name=N'#test___________________________________________________________________________________________________________________00003EE1' and SCHEMA_NAME(sp.schema_id)=N'dbo')
It returns the pure CREATE which is then substituted with ALTER in code somewhere.
The SET ANSI NULL stuff and the GO statements and dates are all prepended to this.
Go with sp_helptext, its simpler ...
I don't think that's possible, you could fake it with double parens ... just as long you don't need the arguments individually.
#define macro(ARGS) some_complicated (whatever ARGS)
// ...
macro((a,b,c))
macro((d,e))
<input type="image" name="your_image_name" src="your_image_url.png" />
This will send the your_image_name.x
and your_image_name.y
values as it submits the form, which are the x and y coordinates of the position the user clicked the image.
Use -to instead of -t: -to specifies the end time, -t specifies the duration
My usecase was replacing None
with some default value.
I've timed approaches to this problem that were presented here, including the one by @kxr - using str.count
.
Test code in ipython with Python 3.8.1:
def rep1(lst, replacer = 0):
''' List comprehension, new list '''
return [item if item is not None else replacer for item in lst]
def rep2(lst, replacer = 0):
''' List comprehension, in-place '''
lst[:] = [item if item is not None else replacer for item in lst]
return lst
def rep3(lst, replacer = 0):
''' enumerate() with comparison - in-place '''
for idx, item in enumerate(lst):
if item is None:
lst[idx] = replacer
return lst
def rep4(lst, replacer = 0):
''' Using str.index + Exception, in-place '''
idx = -1
# none_amount = lst.count(None)
while True:
try:
idx = lst.index(None, idx+1)
except ValueError:
break
else:
lst[idx] = replacer
return lst
def rep5(lst, replacer = 0):
''' Using str.index + str.count, in-place '''
idx = -1
for _ in range(lst.count(None)):
idx = lst.index(None, idx+1)
lst[idx] = replacer
return lst
def rep6(lst, replacer = 0):
''' Using map, return map iterator '''
return map(lambda item: item if item is not None else replacer, lst)
def rep7(lst, replacer = 0):
''' Using map, return new list '''
return list(map(lambda item: item if item is not None else replacer, lst))
lst = [5]*10**6
# lst = [None]*10**6
%timeit rep1(lst)
%timeit rep2(lst)
%timeit rep3(lst)
%timeit rep4(lst)
%timeit rep5(lst)
%timeit rep6(lst)
%timeit rep7(lst)
I get:
26.3 ms ± 163 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
29.3 ms ± 206 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
33.8 ms ± 191 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
11.9 ms ± 37.8 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
11.9 ms ± 60.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
260 ns ± 1.84 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
56.5 ms ± 204 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
Using the internal str.index
is in fact faster than any manual comparison.
I didn't know if the exception in test 4 would be more laborious than using str.count
, the difference seems negligible.
Note that map()
(test 6) returns an iterator and not an actual list, thus test 7.
file='path/test.xml'
with open(file, 'w') as filetowrite:
filetowrite.write('new content')
Open the file in 'w' mode, you will be able to replace its current text save the file with new contents.
You could try my Beavertail ADSI browser - it should show you the current AD tree, and from it, you should be able to figure out the path and all.
Or if you're on .NET 3.5, using the System.DirectoryServices.AccountManagement
namespace, you could also do it programmatically:
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
This would create a basic, default domain context and you should be able to peek at its properties and find a lot of stuff from it.
Or:
UserPrincipal myself = UserPrincipal.Current;
This will give you a UserPrincipal
object for yourself, again, with a ton of properties to inspect. I'm not 100% sure what you're looking for - but you most likely will be able to find it on the context or the user principal somewhere!
-mmin is for minutes.
Try looking at the man page.
man find
for more types.
Updated version of iksnae's awesome answer. It's not a regex, but I think it's the best solution to validate all countries' phone numbers as it is smart enough to know if the country's phone extension code is valid as well.
extension String {
public var validPhoneNumber: Bool {
let types: NSTextCheckingResult.CheckingType = [.phoneNumber]
guard let detector = try? NSDataDetector(types: types.rawValue) else { return false }
if let match = detector.matches(in: self, options: [], range: NSMakeRange(0, self.count)).first?.phoneNumber {
return match == self
} else {
return false
}
}
}
print("\("+96 (123) 456-0990".validPhoneNumber)") //returns false, smart enough to know if country phone code is valid as well
print("\("+994 (123) 456-0990".validPhoneNumber)") //returns true because +994 country code is an actual country phone code
print("\("(123) 456-0990".validPhoneNumber)") //returns true
print("\("123-456-0990".validPhoneNumber)") //returns true
print("\("1234560990".validPhoneNumber)") //returns true
I used FileReader to display image on click of the file upload button not using any Ajax requests. Following is the code hope it might help some one.
$(document).ready(function($) {
$.extend( true, jQuery.fn, {
imagePreview: function( options ){
var defaults = {};
if( options ){
$.extend( true, defaults, options );
}
$.each( this, function(){
var $this = $( this );
$this.bind( 'change', function( evt ){
var files = evt.target.files; // FileList object
// Loop through the FileList and render image files as thumbnails.
for (var i = 0, f; f = files[i]; i++) {
// Only process image files.
if (!f.type.match('image.*')) {
continue;
}
var reader = new FileReader();
// Closure to capture the file information.
reader.onload = (function(theFile) {
return function(e) {
// Render thumbnail.
$('#imageURL').attr('src',e.target.result);
};
})(f);
// Read in the image file as a data URL.
reader.readAsDataURL(f);
}
});
});
}
});
$( '#fileinput' ).imagePreview();
});
dir *.txt /s /p
will give more detailed information.
You could use sed -n 5p file
.
You can also get a range, e.g., sed -n 5,10p file
.
Usually, IllegalStateException
is used to indicate that "a method has been invoked at an illegal or inappropriate time." However, this doesn't look like a particularly typical use of it.
The code you've linked to shows that it can be thrown within that code at line 259 - but only after dumping a SQLException
to standard output.
We can't tell what's wrong just from that exception - and better code would have used the original SQLException
as a "cause" exception (or just let the original exception propagate up the stack) - but you should be able to see more details on standard output. Look at that information, and you should be able to see what caused the exception, and fix it.
Update : As @amram99 mentioned, the issue has been fixed as of the release of Android Studio v1.3.
Tested and verified with below specifications
What works now
Now you can import a local aar file via the File>New>New Module>Import .JAR/.AAR Package option in Android Studio v1.3
However the below answer holds true and effective irrespective of the Android Studio changes as this is based of gradle scripting.
Old Answer : In a recent update the people at android broke the inclusion of local aar files via the Android Studio's add new module menu option. Check the Issue listed here. Irrespective of anything that goes in and out of IDE's feature list , the below method works when it comes to working with local aar files.(Tested it today):
Put the aar file in the libs directory (create it if needed), then, add the following code in your build.gradle :
dependencies {
compile(name:'nameOfYourAARFileWithoutExtension', ext:'aar')
}
repositories{
flatDir{
dirs 'libs'
}
}
I think what you looking for is "joinSub". It's supported from laravel ^5.6. If you using laravel version below 5.6 you can also register it as macro in your app service provider file. like this https://github.com/teamtnt/laravel-scout-tntsearch-driver/issues/171#issuecomment-413062522
$subquery = DB::table('catch-text')
->select(DB::raw("user_id,MAX(created_at) as MaxDate"))
->groupBy('user_id');
$query = User::joinSub($subquery,'MaxDates',function($join){
$join->on('users.id','=','MaxDates.user_id');
})->select(['users.*','MaxDates.*']);
TL;DR
Summary; if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data
. Otherwise, use application/x-www-form-urlencoded
.
The MIME types you mention are the two Content-Type
headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of name/value pairs to the server. Depending on the type and amount of data being transmitted, one of the methods will be more efficient than the other. To understand why, you have to look at what each is doing under the covers.
For application/x-www-form-urlencoded
, the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&
), and names are separated from values by the equals symbol (=
). An example of this would be:
MyVariableOne=ValueOne&MyVariableTwo=ValueTwo
According to the specification:
[Reserved and] non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character
That means that for each non-alphanumeric byte that exists in one of our values, it's going to take three bytes to represent it. For large binary files, tripling the payload is going to be highly inefficient.
That's where multipart/form-data
comes in. With this method of transmitting name/value pairs, each pair is represented as a "part" in a MIME message (as described by other answers). Parts are separated by a particular string boundary (chosen specifically so that this boundary string does not occur in any of the "value" payloads). Each part has its own set of MIME headers like Content-Type
, and particularly Content-Disposition
, which can give each part its "name." The value piece of each name/value pair is the payload of each part of the MIME message. The MIME spec gives us more options when representing the value payload -- we can choose a more efficient encoding of binary data to save bandwidth (e.g. base 64 or even raw binary).
Why not use multipart/form-data
all the time? For short alphanumeric values (like most web forms), the overhead of adding all of the MIME headers is going to significantly outweigh any savings from more efficient binary encoding.
The name reflection is used to describe code which is able to inspect other code in the same system (or itself).
For example, say you have an object of an unknown type in Java, and you would like to call a 'doSomething' method on it if one exists. Java's static typing system isn't really designed to support this unless the object conforms to a known interface, but using reflection, your code can look at the object and find out if it has a method called 'doSomething' and then call it if you want to.
So, to give you a code example of this in Java (imagine the object in question is foo) :
Method method = foo.getClass().getMethod("doSomething", null);
method.invoke(foo, null);
One very common use case in Java is the usage with annotations. JUnit 4, for example, will use reflection to look through your classes for methods tagged with the @Test annotation, and will then call them when running the unit test.
There are some good reflection examples to get you started at http://docs.oracle.com/javase/tutorial/reflect/index.html
And finally, yes, the concepts are pretty much similar in other statically typed languages which support reflection (like C#). In dynamically typed languages, the use case described above is less necessary (since the compiler will allow any method to be called on any object, failing at runtime if it does not exist), but the second case of looking for methods which are marked or work in a certain way is still common.
Update from a comment:
The ability to inspect the code in the system and see object types is not reflection, but rather Type Introspection. Reflection is then the ability to make modifications at runtime by making use of introspection. The distinction is necessary here as some languages support introspection, but do not support reflection. One such example is C++
Replace your file name in package.json
({"npm": <your server code file name>.js}
) with that file where your server code is running (it should be app.js
, main.js
, start.js
, server.js
, or whatever you picked up).
There is no single function that does what you want. Your definition of shift is slightly different than what most people are doing. The ways to shift an array are more commonly looped:
>>>xs=np.array([1,2,3,4,5])
>>>shift(xs,3)
array([3,4,5,1,2])
However, you can do what you want with two functions.
Consider a=np.array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.])
:
def shift2(arr,num):
arr=np.roll(arr,num)
if num<0:
np.put(arr,range(len(arr)+num,len(arr)),np.nan)
elif num > 0:
np.put(arr,range(num),np.nan)
return arr
>>>shift2(a,3)
[ nan nan nan 0. 1. 2. 3. 4. 5. 6.]
>>>shift2(a,-3)
[ 3. 4. 5. 6. 7. 8. 9. nan nan nan]
After running cProfile on your given function and the above code you provided, I found that the code you provided makes 42 function calls while shift2
made 14 calls when arr is positive and 16 when it is negative. I will be experimenting with timing to see how each performs with real data.
try the following as there will be no varchar conversion
SELECT Subject, CAST(DeliveryDate AS DATE)
from Email_Administration
where MerchantId =@ MerchantID
I had the same problem and found out that I had forgotten to include the script in the file which I want to include in the live site.
Also, you should try this:
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
You can add
from functools import reduce
before you use the reduce.
You mean something like this?
<?php
$jsonurl = "http://search.twitter.com/trends.json";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);
foreach ( $json_output->trends as $trend )
{
echo "{$trend->name}\n";
}
You had the identity
node as a child of authentication
node. That was the issue. As in the example above, authentication
and identity
nodes must be children of the system.web
node
And most important!!!
When you change a namespace in your code, also make sure you change it in web.config!
In addition to previous answers there is one important for me note:
shelve
is JetBrains products feature (such as WebStorm
, PhpStorm
, PyCharm
, etc.). It puts shelved files into .idea/shelf
directory.
stash
is one of git
options. It puts stashed files under the .git
directory.
My Problem was that I was not in the correct git directory that I just cloned.
Modern string formatting:
"{} and {}".format("string", 1)
I don't know that much about batch files but couldn't you have a pre-made batch file copied from the home directory to the path you have that would return a list of the names of the files then use that name?
Here is a link I think might be helpful in making the pre-made batch file.
Since nullptr
is never going to be returned, I recommend the reference approach. It more accurately represents how the return value will be used.
You can use geom_col() directly. See the differences between geom_bar() and geom_col() in this link https://ggplot2.tidyverse.org/reference/geom_bar.html
geom_bar() makes the height of the bar proportional to the number of cases in each group If you want the heights of the bars to represent values in the data, use geom_col() instead.
ggplot(data_country)+aes(x=country,y = conversion_rate)+geom_col()
GitHub pages host only static HTML pages. No server side technology is supported, so Node.js applications won't run on GitHub pages. There are lots of hosting providers, as listed on the Node.js wiki.
App fog seems to be the most economical as it provides free hosting for projects with 2GB of RAM (which is pretty good if you ask me).
As stated here, AppFog removed their free plan for new users.
If you want to host static pages on GitHub, then read this guide. If you plan on using Jekyll, then this guide will be very helpful.
Fast, compact, no nested loops, works with any object not just strings and numbers, takes a predicate, and only 5 lines of code!!
function findUnique(arr, predicate) {
var found = {};
arr.forEach(d => {
found[predicate(d)] = d;
});
return Object.keys(found).map(key => found[key]);
}
Example: To find unique items by type:
var things = [
{ name: 'charm', type: 'quark'},
{ name: 'strange', type: 'quark'},
{ name: 'proton', type: 'boson'},
];
var result = findUnique(things, d => d.type);
// [
// { name: 'charm', type: 'quark'},
// { name: 'proton', type: 'boson'}
// ]
If you want it to find the first unique item instead of the last add a found.hasOwnPropery() check in there.
Firstly, thanks to Andrei as I've based my solution on his example.
I'm including mine as it's a more complete sample and might save readers some time.
The limitation of Andrei's approach is that doesn't handle logging, capturing potentially useful request variables and content negotiation (it will always return JSON no matter what the client has requested - XML / plain text etc).
My approach is to use an ObjectResult which allows us to use the functionality baked into MVC.
This code also prevents caching of the response.
The error response has been decorated in such a way that it can be serialized by the XML serializer.
public class ExceptionHandlerMiddleware
{
private readonly RequestDelegate next;
private readonly IActionResultExecutor<ObjectResult> executor;
private readonly ILogger logger;
private static readonly ActionDescriptor EmptyActionDescriptor = new ActionDescriptor();
public ExceptionHandlerMiddleware(RequestDelegate next, IActionResultExecutor<ObjectResult> executor, ILoggerFactory loggerFactory)
{
this.next = next;
this.executor = executor;
logger = loggerFactory.CreateLogger<ExceptionHandlerMiddleware>();
}
public async Task Invoke(HttpContext context)
{
try
{
await next(context);
}
catch (Exception ex)
{
logger.LogError(ex, $"An unhandled exception has occurred while executing the request. Url: {context.Request.GetDisplayUrl()}. Request Data: " + GetRequestData(context));
if (context.Response.HasStarted)
{
throw;
}
var routeData = context.GetRouteData() ?? new RouteData();
ClearCacheHeaders(context.Response);
var actionContext = new ActionContext(context, routeData, EmptyActionDescriptor);
var result = new ObjectResult(new ErrorResponse("Error processing request. Server error."))
{
StatusCode = (int) HttpStatusCode.InternalServerError,
};
await executor.ExecuteAsync(actionContext, result);
}
}
private static string GetRequestData(HttpContext context)
{
var sb = new StringBuilder();
if (context.Request.HasFormContentType && context.Request.Form.Any())
{
sb.Append("Form variables:");
foreach (var x in context.Request.Form)
{
sb.AppendFormat("Key={0}, Value={1}<br/>", x.Key, x.Value);
}
}
sb.AppendLine("Method: " + context.Request.Method);
return sb.ToString();
}
private static void ClearCacheHeaders(HttpResponse response)
{
response.Headers[HeaderNames.CacheControl] = "no-cache";
response.Headers[HeaderNames.Pragma] = "no-cache";
response.Headers[HeaderNames.Expires] = "-1";
response.Headers.Remove(HeaderNames.ETag);
}
[DataContract(Name= "ErrorResponse")]
public class ErrorResponse
{
[DataMember(Name = "Message")]
public string Message { get; set; }
public ErrorResponse(string message)
{
Message = message;
}
}
}
table {
border: 1px solid transparent;
}
You can implement this functionality like this
Firstly, using the ls command pointed to the targeted directory. Later using find command filter the result from it.
From your case, it sounds like - always the filename starts with a word
file***.txt
ls /some/path/here | find . -name 'file*.txt' (* represents some wild card search)
What about detached or unrelated shells and code [args]
support?
While other answers talk about how to configure and use the VScode integrated WSL bash
terminal support, they don't solve the problem of "detached shells": shells which were not launched from within VScode, or which somehow get "disconnected" from the VScode server instance associated with the IDE.
Such shells can give errors like:
Command is only available in WSL or inside a Visual Studio Code terminal.
or...
Unable to connect to VS Code server.
Error in request
Here's a script which makes it easy to solve this problem.
I use this daily to connect shells in a tmux
session with a specific VScode server instance, or to fix an integrated shell that's become detached from its hosting IDE.
#!/bin/bash
# codesrv-connect
#
# Purpose:
# Copies the vscode connection environment from one shell to another, so that you can use the
# vscode integrated terminal's "code [args]" command to communicate with that instance of vscode
# from an unrelated shell.
#
# Usage:
# 1. Open an integrated terminal in vscode, and run codesrv-connect
# 2. In the target shell, cd to the same directory and run
# ". .codesrv-connect", or follow the instruction printed by codesrv-connect.
#
# Setup:
# Put "codesrv-connect somewhere on your PATH (e.g. ~/bin)"
#
# Cleanup:
# - Delete abandoned .codesrv-connect files when their vscode sessions die.
# - Do not add .codesrv-connect files to git repositories.
#
# Notes:
# The VSCODE_IPC_HOOK_CLI environment variable points to a socket which is rather volatile, while the long path for the 'code' alias is more stable: vscode doesn't change the latter even across a "code -r ." reload. But the former is easily detached and so you need a fresh value if that happens. This is what codesrv-connect does: it captures the value of these two and writes them to .codesrv-connect in the current dir.

if ! test -S "$VSCODE_IPC_HOOK_CLI"; then

else
export VSCODE_IPC_HOOK_CLI="$VSCODE_IPC_HOOK_CLI"
alias code=$(which code)
echo "Done: the 'code' command will talk to socket \"$VSCODE_IPC_HOOK_CLI\" now."
echo "You can delete .codesrv-connect when the vscode server context dies, or reuse it in other shells until then."

With the help of ceztko's answer I wrote this little helper function to make my life easier:
function gpu()
{
if git rev-parse --abbrev-ref --symbolic-full-name @{u} > /dev/null 2>&1; then
git push origin HEAD
else
git push -u origin HEAD
fi
}
It pushes the current branch to origin and also sets the remote tracking branch if it hasn't been setup yet.
For additional details see the SVNBook: "Status of working copy files and directories".
The common statuses:
U: Working file was updated
G: Changes on the repo were automatically merged into the working copy
M: Working copy is modified
C: This file conflicts with the version in the repo
?: This file is not under version control
!: This file is under version control but is missing or incomplete
A: This file will be added to version control (after commit)
A+: This file will be moved (after commit)
D: This file will be deleted (after commit)
S: This signifies that the file or directory has been switched from the path of the rest of the working copy (using svn switch) to a branch
I: Ignored
X: External definition
~: Type changed
R: Item has been replaced in your working copy. This means the file was scheduled for deletion, and then a new file with the same name was scheduled for addition in its place.
L : Item is locked
E: Item existed, as it would have been created, by an svn update.
The quick generic answer:
std::vector<double> vec(carray,carray+carray_size);
or question specific:
std::vector<double> w_(w,w+len);
based on above: Don't forget that you can treat pointers as iterators
You can use this Javascript :
function getParameterByName(name) {
var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
You can also use the plugin jQuery-URL-Parser allows to retrieve all parts of URL, including anchor, host, etc.
Usage is very simple and cool:
$.url().param("itemID")

Changing IE's JSON mime-type settings will effect the way IE treats all JSON responses.
Changing the mime-type header to text/html will effectively tell any browser that the JSON response you are returning is not JSON but plain text.
Neither options are preferable.
Instead you would want to use a plugin or tool like the above mentioned Fiddler or any other network traffic inspector proxy where you can choose each time how to process the JSON response.
It is not listed as a function in dplyr (yet): http://cran.rstudio.org/web/packages/dplyr/dplyr.pdf
The function below works (almost) the same if you don't want to load both plyr and dplyr
rename <- function(dat, oldnames, newnames) {
datnames <- colnames(dat)
datnames[which(datnames %in% oldnames)] <- newnames
colnames(dat) <- datnames

I found that just using the connectivity package was not enough to tell if the internet was available or not. In Android it only checks if there is WIFI or if mobile data is turned on, it does not check for an actual internet connection . During my testing, even with no mobile signal ConnectivityResult.mobile would return true.
With IOS my testing found that the connectivity plugin does correctly detect if there is an internet connection when the phone has no signal, the issue was only with Android.
The solution I found was to use the data_connection_checker package along with the connectivity package. This just makes sure there is an internet connection by making requests to a few reliable addresses, the default timeout for the check is around 10 seconds.
My finished isInternet function looked a bit like this:
Future<bool> isInternet() async {
var connectivityResult = await (Connectivity().checkConnectivity());
if (connectivityResult == ConnectivityResult.mobile) {
// I am connected to a mobile network, make sure there is actually a net connection.
if (await DataConnectionChecker().hasConnection) {
// Mobile data detected & internet connection confirmed.
return true;
} else {
// Mobile data detected but no internet connection found.
return false;
}
} else if (connectivityResult == ConnectivityResult.wifi) {
// I am connected to a WIFI network, make sure there is actually a net connection.
if (await DataConnectionChecker().hasConnection) {
// Wifi detected & internet connection confirmed.
return true;
} else {
// Wifi detected but no internet connection found.
return false;
}
} else {
// Neither mobile data or WIFI detected, not internet connection found.
return false;
}
}
The if (await DataConnectionChecker().hasConnection)
part is the same for both mobile and wifi connections and should probably be moved to a separate function. I've not done that here to leave it more readable.
This is my first Stack Overflow answer, hope it helps someone.
I know this is old and whatnot (and not exactly sure if it's a question), but after searching, I had success with this command for --onefile
:
pyinstaller.exe --onefile --windowed --icon=app.ico app.py
Google led me to this page while I was searching for an answer on how to set an icon for my .exe, so maybe it will help someone else.
The information here was found at this site: https://mborgerson.com/creating-an-executable-from-a-python-script
Technically the information is available to you, but as others have asked, how would you make use of it in a sensible way?
>>> x = 52
>>> globals()
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__',
'x': 52, '__doc__': None, '__package__': None}
This shows that the variable name is present as a string in the globals() dictionary.
>>> globals().keys()[2]
'x'
In this case it happens to be the third key, but there's no reliable way to know where a given variable name will end up
>>> for k in globals().keys():
... if not k.startswith("_"):
... print k
...
x
>>>
You could filter out system variables like this, but you're still going to get all of your own items. Just running that code above created another variable "k" that changed the position of "x" in the dict.
But maybe this is a useful start for you. If you tell us what you want this capability for, more helpful information could possibly be given.
Of????? course there is Mono.
I prefer simplicity...
private void _InvokeNamespaceClassesStaticMethod(string namespaceName, string methodName, params object[] parameters) {
foreach(var _a in AppDomain.CurrentDomain.GetAssemblies()) {
foreach(var _t in _a.GetTypes()) {
try {
if((_t.Namespace == namespaceName) && _t.IsClass) _t.GetMethod(methodName, (BindingFlags.Static | BindingFlags.Public))?.Invoke(null, parameters);
} catch { }
}
}
}
Usage...
_InvokeNamespaceClassesStaticMethod("mySolution.Macros", "Run");
But in case you're looking for something a little more robust, including the handling of exceptions...
private InvokeNamespaceClassStaticMethodResult[] _InvokeNamespaceClassStaticMethod(string namespaceName, string methodName, bool throwExceptions, params object[] parameters) {
var results = new List<InvokeNamespaceClassStaticMethodResult>();
foreach(var _a in AppDomain.CurrentDomain.GetAssemblies()) {
foreach(var _t in _a.GetTypes()) {
if((_t.Namespace == namespaceName) && _t.IsClass) {
var method_t = _t.GetMethod(methodName, parameters.Select(_ => _.GetType()).ToArray());
if((method_t != null) && method_t.IsPublic && method_t.IsStatic) {
var details_t = new InvokeNamespaceClassStaticMethodResult();
details_t.Namespace = _t.Namespace;
details_t.Class = _t.Name;
details_t.Method = method_t.Name;
try {
if(method_t.ReturnType == typeof(void)) {
method_t.Invoke(null, parameters);
details_t.Void = true;
} else {
details_t.Return = method_t.Invoke(null, parameters);
}
} catch(Exception ex) {
if(throwExceptions) {
throw;
} else {
details_t.Exception = ex;
}
}
results.Add(details_t);
}
}
}
}
return results.ToArray();
}
private class InvokeNamespaceClassStaticMethodResult {
public string Namespace;
public string Class;
public string Method;
public object Return;
public bool Void;
public Exception Exception;
}
Usage is pretty much the same...
_InvokeNamespaceClassesStaticMethod("mySolution.Macros", "Run", false);
For anyone want to get time elapsed value instead of console output :
use process.hrtime() as @D.Deriso suggestion, below is my simpler approach :
function functionToBeMeasured() {
var startTime = process.hrtime();
// do some task...
// ......
var elapsedSeconds = parseHrtimeToSeconds(process.hrtime(startTime));
console.log('It takes ' + elapsedSeconds + 'seconds');
}
function parseHrtimeToSeconds(hrtime) {
var seconds = (hrtime[0] + (hrtime[1] / 1e9)).toFixed(3);
return seconds;
}
I install go launcher on mine, (Windows 8)=> preferences => Screens => Screen orientation => vertical (disable QWE keyboard)
A little hacky, but I created an array called "console", and anytime I wanted to output to console I pushed to the array. Then whenever I wanted to see the actual output, I just returned console
instead of whatever I was returning before.
//return 'console' //uncomment to output console
return "actual output";
}
Using Ref forwarding you can pass the ref from parent to further down to a child.
const FancyButton = React.forwardRef((props, ref) => (
<button ref={ref} className="FancyButton">
{props.children}
</button>
));
// You can now get a ref directly to the DOM button:
const ref = React.createRef();
<FancyButton ref={ref}>Click me!</FancyButton>;
Note The second ref argument only exists when you define a component with React.forwardRef call. Regular functional or class components don’t receive the ref argument, and ref is not available in props either.
Ref forwarding is not limited to DOM components. You can forward refs to class component instances, too.
Reference: React Documentation.
I would do something like:
$(documento).on('click', '#answer', function() {
feedback('hey there');
});
A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
The problem is twofold:
.
in the routeBy default, IIS treats all URI's with a dot in them as static resource, tries to return it and skip further processing (by Web API) altogether. This is configured in your Web.config in the section system.webServer.handlers
: the default handler handles path="*."
. You won't find much documentation regarding the strange syntax in this path
attribute (regex would have made more sense), but what this apparently means is "anything that doesn't contain a dot" (and any character from point 2 below). Hence the 'Extensionless' in the name ExtensionlessUrlHandler-Integrated-4.0
.
Multiple solutions are possible, in my opinion in the order of 'correctness':
path="*."
attribute to path="*"
. It will then catch everything. Note that from then on, your web api will no longer interpret incoming calls with dots as static resources! If you are hosting static resources on your web api, this is therefor not advised!<system.webserver>
: <modules runAllManagedModulesForAllRequests="true">
:
in the routeAfter you've changed the above, by default, you'd get the following error:
A potentially dangerous Request.Path value was detected from the client (:).
You can change the predefined disallowed/invalid characters in your Web.config. Under <system.web>
, add the following: <httpRuntime requestPathInvalidCharacters="<,>,%,&,*,\,?" />
. I've removed the :
from the standard list of invalid characters.
Although not an answer to your question, a safer and easier solution would be to change the request so that all this is not required. This can be done in two ways:
?date=2012-12-31T22:00:00.000Z
..000
from every request. You'd still need to allow :

I had the same question for macOS.
But the root cause was not installing Six. My macOS shipped Python version 2.7 was being usurped by a Python2 version I inherited by installing a package via brew
.
I fixed my issue with: $ brew uninstall python@2

This is a bit late, but if you are using Spring Data REST then there is already org.springframework.data.rest.webmvc.ResourceNotFoundException
It also uses @ResponseStatus
annotation. There is no need to create a custom runtime exception anymore.
If you know you're always going to use bash, it's much easier to always use the double bracket conditional compound command [[ ... ]]
, instead of the Posix-compatible single bracket version [ ... ]
. Inside a [[ ... ]]
compound, word-splitting and pathname expansion are not applied to words, so you can rely on
if [[ $aug1 == "and" ]];
to compare the value of $aug1
with the string and
.
If you use [ ... ]
, you always need to remember to double quote variables like this:
if [ "$aug1" = "and" ];
If you don't quote the variable expansion and the variable is undefined or empty, it vanishes from the scene of the crime, leaving only
if [ = "and" ];
which is not a valid syntax. (It would also fail with a different error message if $aug1
included white space or shell metacharacters.)
The modern [[
operator has lots of other nice features, including regular expression matching.
JsonObject jsonObject = (JsonObject) new JsonParser().parse("YourJsonString");
As we read in this answer, HTML5 will solve this for you if you're open to that route. HTML5 audio is supported in all modern browsers.

I just needed a simple testing button for react.js. Here is what I did and it worked.

var f=function testing(){

};
console.log("Testing Mode");
return (<div><button onClick={f}>testing</button></div>);
}
You could target all text boxes with input[type=text]
and then explicitly define the class for the textboxes who need it.
You can code like below :
input[type=text] {_x000D_
padding: 0;_x000D_
height: 30px;_x000D_
position: relative;_x000D_
left: 0;_x000D_
outline: none;_x000D_
border: 1px solid #cdcdcd;_x000D_
border-color: rgba(0, 0, 0, .15);_x000D_
background-color: white;_x000D_
font-size: 16px;_x000D_
}_x000D_
_x000D_
.advancedSearchTextbox {_x000D_
width: 526px;_x000D_
margin-right: -4px;_x000D_
}
_x000D_
<input type="text" class="advancedSearchTextBox" />
_x000D_
To much code, you can use it like this:
#include<array>
#include<functional>
int main()
{
std::array<int, 10> vec = { 1,2,3,4,5,6,7,8,9 };
std::sort(std::begin(vec),
std::end(vec),
[](int a, int b) {return a > b; });
for (auto item : vec)
std::cout << item << " ";
return 0;
}
Replace "vec" with your class and that's it.

Simple binary threshold method is sufficient.
#include <string>
#include "opencv/highgui.h"
#include "opencv2/imgproc/imgproc.hpp"
using namespace std;
using namespace cv;
int main()
{
Mat img = imread("./img.jpg",0);//loading gray scale image
threshold(img, img, 128, 255, CV_THRESH_BINARY);//threshold binary, you can change threshold 128 to your convenient threshold
imwrite("./black-white.jpg",img);
return 0;
}
You can use GaussianBlur
to get a smooth black and white image.
Image shown below. I'm only typing this because of a 30 character minimum imposed by Stackoverflow.
Easiest way:
// Prefs.h
#define PREFS_MY_CONSTANT @"prefs_my_constant"
Better way:
// Prefs.h
extern NSString * const PREFS_MY_CONSTANT;
// Prefs.m
NSString * const PREFS_MY_CONSTANT = @"prefs_my_constant";
One benefit of the second is that changing the value of a constant does not cause a rebuild of your entire program.

I am assuming you have site key and secret in place. Follow this step.
In your HTML file, add the script.
<script src="https://www.google.com/recaptcha/api.js?render=put your site key here"></script>
Also, do use jQuery for easy event handling.
Here is the simple form.
<form id="comment_form" action="form.php" method="post" >
<input type="email" name="email" placeholder="Type your email" size="40"><br><br>
<textarea name="comment" rows="8" cols="39"></textarea><br><br>
<input type="submit" name="submit" value="Post comment"><br><br>
</form>
You need to initialize the Google recaptcha and listen for the ready event. Here is how to do that.
<script>
// when form is submit
$('#comment_form').submit(function() {
// we stoped it
event.preventDefault();
var email = $('#email').val();
var comment = $("#comment").val();
// needs for recaptacha ready
grecaptcha.ready(function() {
// do request for recaptcha token
// response is promise with passed token
grecaptcha.execute('put your site key here', {action: 'create_comment'}).then(function(token) {
// add token to form
$('#comment_form').prepend('<input type="hidden" name="g-recaptcha-response" value="' + token + '">');
$.post("form.php",{email: email, comment: comment, token: token}, function(result) {
console.log(result);
if(result.success) {
alert('Thanks for posting comment.')
} else {
alert('You are spammer ! Get the @$%K out.')
}
});
});
});
});
</script>
Here is the sample PHP file. You can use Servlet or Node or any backend language in place of it.
<?php
$email;$comment;$captcha;
if(isset($_POST['email'])){
$email=$_POST['email'];
}if(isset($_POST['comment'])){
$comment=$_POST['comment'];
}if(isset($_POST['token'])){
$captcha=$_POST['token'];
}
if(!$captcha){
echo '<h2>Please check the the captcha form.</h2>';
exit;
}
$secretKey = "put your secret key here";
$ip = $_SERVER['REMOTE_ADDR'];
// post request to server
$url = 'https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secretKey) . '&response=' . urlencode($captcha);
$response = file_get_contents($url);
$responseKeys = json_decode($response,true);
header('Content-type: application/json');
if($responseKeys["success"]) {
echo json_encode(array('success' => 'true'));
} else {
echo json_encode(array('success' => 'false'));
}
?>

Just add catch all route at the end of the routes table and display whatever page you want with it.
See: How can i make a catch all route to handle '404 page not found' queries for ASP.NET MVC?
To improve performance of the operation, if you're always going to want to look up objects by some unique identifier, then you might consider using a Map<Integer,Dog>
. This will provide constant-time lookup by key. You can still iterate over the objects themselves using the map values()
.
A quick code fragment to get you started:
// Populate the map
Map<Integer,Dog> dogs = new HashMap<Integer,Dog>();
for( Dog dog : /* dog source */ ) {
dogs.put( dog.getId(), dog );
}
// Perform a lookup
Dog dog = dogs.get( id );
This will help speed things up a bit if you're performing multiple lookups of the same nature on the list. If you're just doing the one lookup, then you're going to incur the same loop overhead regardless.
If you don't want to do it all by yourself, you can use the random.randrange function.
For example import random; print random.randrange(10, 25, 5)
prints a number that is between 10 and 25 (10 included, 25 excluded) and is a multiple of 5. So it would print 10, 15, or 20.
pip
is just a PyPI package like any other; you could use it to upgrade itself the same way you would upgrade any package:
pip install --upgrade pip
On Windows the recommended command is:
python -m pip install --upgrade pip
If you really need this you can achieve your goal with help of separate table for sequencing (if you don't mind) and a trigger.
Tables
CREATE TABLE table1_seq
(
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
CREATE TABLE table1
(
id VARCHAR(7) NOT NULL PRIMARY KEY DEFAULT '0', name VARCHAR(30)
);
Now the trigger
DELIMITER $$
CREATE TRIGGER tg_table1_insert
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
INSERT INTO table1_seq VALUES (NULL);
SET NEW.id = CONCAT('LHPL', LPAD(LAST_INSERT_ID(), 3, '0'));
END$$
DELIMITER ;
Then you just insert rows to table1
INSERT INTO Table1 (name)
VALUES ('Jhon'), ('Mark');
And you'll have
| ID | NAME | ------------------ | LHPL001 | Jhon | | LHPL002 | Mark |

Linear Search
looks through items until it finds the searched value.
Efficiency: O(n)
Example Python Code:
test_list = [1, 3, 9, 11, 15, 19, 29]
test_val1 = 25
test_val2 = 15
def linear_search(input_array, search_value):
index = 0
while (index < len(input_array)) and (input_array[index] < search_value):
index += 1
if index >= len(input_array) or input_array[index] != search_value:
return -1
return index
print linear_search(test_list, test_val1)
print linear_search(test_list, test_val2)
Binary Search
finds the middle element of the array. Checks that middle value is greater or lower than the search value. If it is smaller, it gets the left side of the array and finds the middle element of that part. If it is greater, gets the right part of the array. It loops the operation until it finds the searched value. Or if there is no value in the array finishes the search.
Efficiency: O(logn)
Example Python Code:
test_list = [1, 3, 9, 11, 15, 19, 29]
test_val1 = 25
test_val2 = 15
def binary_search(input_array, value):
low = 0
high = len(input_array) - 1
while low <= high:
mid = (low + high) / 2
if input_array[mid] == value:
return mid
elif input_array[mid] < value:
low = mid + 1
else:
high = mid - 1
return -1
print binary_search(test_list, test_val1)
print binary_search(test_list, test_val2)
Also you can see visualized information about Linear and Binary Search here: https://www.cs.usfca.edu/~galles/visualization/Search.html

I just had the same problem as you, but found out about the toDataURL method, which proved useful.
The gist of it is to turn your current canvas into a dataURL, change your canvas size, and then draw what you had back into your canvas from the dataURL you saved.
So here's my code:
var oldCanvas = canvas.toDataURL("image/png");
var img = new Image();
img.src = oldCanvas;
img.onload = function (){
canvas.height += 100;
ctx.drawImage(img, 0, 0);
}
tr {
display: block;
margin-bottom: 5px;

Perhaps your subquery (SELECT ename FROM EMP WHERE empno = mgr)
thinks, give me the employee records that are their own managers! (i.e., where the empno of a row is the same as the mgr of the same row.)
have you considered perhaps rewriting this to use an inner (self) join? (I'm asking, becuase i'm not even sure if the following will work or not.)
SELECT t1.ename, t1.empno, t2.ename as MANAGER, t1.mgr
from emp as t1
inner join emp t2 ON t1.mgr = t2.empno
order by t1.empno;
If I remember correctly, you'll need to set the netbeans_jdkhome
property in your netbeans config file. Should be in your etc/netbeans.conf
file.
Similar to the above solutions I used @Input()
in a directive and able to pass multiple arrays of values in the directive.
selector: '[selectorHere]',
@Input() options: any = {};
Input.html
<input selectorHere [options]="selectorArray" />
Array from TS file
selectorArray= {
align: 'left',
prefix: '$',
thousands: ',',
decimal: '.',
precision: 2
};
Most of the above mentioned solution didn't worked for me. However, below given solution works just fine:
<div class="fixed-bottom">...</div>
Have you checked that those classes are present in the CSS? Are you using twitter-bootstrap-rails gem? It still uses Bootstrap 2.X version and those are Bootstrap 3.X classes. The CSS grid changed since.
You can switch to the bootstrap3 branch of the gem https://github.com/seyhunak/twitter-bootstrap-rails/tree/bootstrap3 or include boostrap in an alternative way.
Well it seems that you are missing a reference to some library. I had the similar error solved it by adding a reference to the #pragma comment(lib, "windowscodecs.lib")

It is certainly possible to access a remote MySQL server from a local instance of phpMyAdmin, as the other answers have pointed out. And for that to work, you have to configure the remote server's MySQL server to accept remote connections, and allow traffic through the firewall for the port number that MySQL is listening to. I prefer a slightly different solution involving SSH Tunnelling.
The following command will set up an SSH tunnel which will forward all requests made to port 3307 from your local machine to port 3306 on the remote machine:
ssh -NL 3307:localhost:3306 root@REMOTE_HOST
When prompted, you should enter the password for the root user on the remote machine. This will open the tunnel. If you want to run this in the background, you'll need to add the -f
argument, and set up Passwordless SSH between your local machine and the remote machine.
After you've got the SSH tunnel working, you can add the remote server to the servers list in your local phpMyAdmin by modifying the /etc/phpmyadmin/config.inc.php
file. Add the following to the end of the file:
$cfg['Servers'][$i]['verbose'] = 'Remote Server 1'; // Change this to whatever you like.
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['port'] = '3307';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['compress'] = FALSE;
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$i++;
I wrote a more in-depth blog post about exactly this, in case you need additional help.
Wunderbart's post worked for me combined with statler's improvements. Adding a few more comments and syntax cleanup, and also passing back the orientation value and I have the following code feel free to use. Just call readImageFile()
function below and you get back the transformed image and the original orientation.
const JpegOrientation = [
"NOT_JPEG",
"NORMAL",
"FLIP-HORIZ",
"ROT180",
"FLIP-HORIZ-ROT180",
"FLIP-HORIZ-ROT270",
"ROT270",
"FLIP-HORIZ-ROT90",
"ROT90"
];
//Provided a image file, determines the orientation of the file based on the EXIF information.
//Calls the "callback" function with an index into the JpegOrientation array.
//If the image is not a JPEG, returns 0. If the orientation value cannot be read (corrupted file?) return -1.
function getOrientation(file, callback) {
const reader = new FileReader();
reader.onload = (e) => {
const view = new DataView(e.target.result);
if (view.getUint16(0, false) !== 0xFFD8) {
return callback(0); //NOT A JPEG FILE
}
const length = view.byteLength;
let offset = 2;
while (offset < length) {
if (view.getUint16(offset+2, false) <= 8) //unknown?
return callback(-1);
const marker = view.getUint16(offset, false);
offset += 2;
if (marker === 0xFFE1) {
if (view.getUint32(offset += 2, false) !== 0x45786966)
return callback(-1); //unknown?
const little = view.getUint16(offset += 6, false) === 0x4949;
offset += view.getUint32(offset + 4, little);
const tags = view.getUint16(offset, little);
offset += 2;
for (var i = 0; i < tags; i++) {
if (view.getUint16(offset + (i * 12), little) === 0x0112) {
return callback(view.getUint16(offset + (i * 12) + 8, little)); //found orientation code
}
}
}
else if ((marker & 0xFF00) !== 0xFF00) {
break;

Try this regex:
^(\+?\d{1,4}[\s-])?(?!0+\s+,?$)\d{10}\s*,?$
Explanation of the regex using Perl's YAPE is as below:
NODE EXPLANATION
----------------------------------------------------------------------
(?-imsx: group, but do not capture (case-sensitive)
(with ^ and $ matching normally) (with . not
matching \n) (matching whitespace and #
normally):
----------------------------------------------------------------------
^ the beginning of the string
----------------------------------------------------------------------
( group and capture to \1 (optional
(matching the most amount possible)):
----------------------------------------------------------------------
\+? '+' (optional (matching the most amount
possible))
----------------------------------------------------------------------
\d{1,4} digits (0-9) (between 1 and 4 times
(matching the most amount possible))
----------------------------------------------------------------------
[\s-] any character of: whitespace (\n, \r,
\t, \f, and " "), '-'
----------------------------------------------------------------------
)? end of \1 (NOTE: because you are using a
quantifier on this capture, only the LAST
repetition of the captured pattern will be
stored in \1)
----------------------------------------------------------------------
(?! look ahead to see if there is not:
----------------------------------------------------------------------
0+ '0' (1 or more times (matching the most
amount possible))
----------------------------------------------------------------------
\s+ whitespace (\n, \r, \t, \f, and " ") (1
or more times (matching the most amount
possible))
----------------------------------------------------------------------
,? ',' (optional (matching the most amount
possible))
----------------------------------------------------------------------
$ before an optional \n, and the end of
the string
----------------------------------------------------------------------
) end of look-ahead
----------------------------------------------------------------------
\d{10} digits (0-9) (10 times)
----------------------------------------------------------------------
\s* whitespace (\n, \r, \t, \f, and " ") (0 or
more times (matching the most amount
possible))
----------------------------------------------------------------------
,? ',' (optional (matching the most amount
possible))
----------------------------------------------------------------------
$ before an optional \n, and the end of the
string
----------------------------------------------------------------------
) end of grouping
----------------------------------------------------------------------
You can also use template matching to detect shapes inside an image.
If you are using Typescript 3.7 or newer you can now also do:
const data = change?.after?.data();
if(!data) {
console.error('No data here!');
return null
}
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
Typescript is saying that change
or data
is possibly undefined
(depending on what onUpdate
returns).
So you should wrap it in a null/undefined check:
if(change && change.after && change.after.data){
const data = change.after.data();
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
}
If you are 100% sure that your object
is always defined then you can put this:
const data = change.after!.data();
Using the accepted solution, I was finding that my "1.1" (when using the .floatValue conversion) would get converted to 1.10000002384186, which was not what I wanted. However, if I used the .doubleValue instead, I would get the 1.1 that I wanted.
So for example, instead of using the accepted solution, I used this instead:
var WageConversion = (Wage.text as NSString).doubleValue
In my case I did not need double-precision, but using the .floatValue was not giving me the proper result.
Just wanted to add this to the discussion in case someone else had been running into the same issue.
For .Net core i had many problems using SSH.net and also its deprecated. I tried a few other libraries, even for other programming languages. But i found a very good alternative. https://stackoverflow.com/a/64443701/8529170

Swift 3
Orientation rotation is more complicated if a view controller is embedded in UINavigationController or UITabBarController the navigation or tab bar controller takes precedence and makes the decisions on autorotation and supported orientations.
Use the following extensions on UINavigationController and UITabBarController so that view controllers that are embedded in one of these controllers get to make the decisions:
UINavigationController extension
extension UINavigationController {
override open var shouldAutorotate: Bool {
get {
if let visibleVC = visibleViewController {
return visibleVC.shouldAutorotate
}
return super.shouldAutorotate
}
}
override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
get {
if let visibleVC = visibleViewController {
return visibleVC.preferredInterfaceOrientationForPresentation
}
return super.preferredInterfaceOrientationForPresentation
}
}
override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
get {
if let visibleVC = visibleViewController {
return visibleVC.supportedInterfaceOrientations
}
return super.supportedInterfaceOrientations
}
}}
UITabBarController extension
extension UITabBarController {
override open var shouldAutorotate: Bool {
get {
if let selectedVC = selectedViewController{
return selectedVC.shouldAutorotate
}
return super.shouldAutorotate
}
}
override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
get {
if let selectedVC = selectedViewController{
return selectedVC.preferredInterfaceOrientationForPresentation
}
return super.preferredInterfaceOrientationForPresentation
}
}
override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
get {
if let selectedVC = selectedViewController{
return selectedVC.supportedInterfaceOrientations
}
return super.supportedInterfaceOrientations
}
}}
Now you can override the supportedInterfaceOrientations, shouldAutoRotate and preferredInterfaceOrientationForPresentation in the view controller you want to lock down otherwise you can leave out the overrides in other view controllers that you want to inherit the default orientation behavior specified in your app's plist.
Lock to Specific Orientation
class YourViewController: UIViewController {
open override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
get {
return .portrait
}
}}
Disable Rotation
class YourViewController: UIViewController {
open override var shouldAutorotate: Bool {
get {
return false
}
}}
Change Preferred Interface Orientation For Presentation
class YourViewController: UIViewController {
open override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
get {
return .portrait
}
}}
With Object.fromEntries
, you can convert from Array
to Object
:
var entries = [_x000D_
['cardType', 'iDEBIT'],_x000D_
['txnAmount', '17.64'],_x000D_
['txnId', '20181'],_x000D_
['txnType', 'Purchase'],_x000D_
['txnDate', '2015/08/13 21:50:04'],_x000D_
['respCode', '0'],_x000D_
['isoCode', '0'],_x000D_
['authCode', ''],_x000D_
['acquirerInvoice', '0'],_x000D_
['message', ''],_x000D_
['isComplete', 'true'],_x000D_
['isTimeout', 'false']_x000D_
];_x000D_
var obj = Object.fromEntries(entries);_x000D_
console.log(obj);
_x000D_
For .NET Core 2.2, you can use FormattableString
for dynamic SQL.
//Assuming this is your dynamic value and this not coming from user input
var tableName = "LogTable";
// let's say target date is coming from user input
var targetDate = DateTime.Now.Date.AddDays(-30);
var param = new SqlParameter("@targetDate", targetDate);
var sql = string.Format("Delete From {0} Where CreatedDate < @targetDate", tableName);
var froamttedSql = FormattableStringFactory.Create(sql, param);
_db.Database.ExecuteSqlCommand(froamttedSql);
I have nothing against libraries in general. In this case a general purpose library seems overkill, unless other parts of the application process dates heavily.
Writing small utility functions such as this is also a useful exercise for both beginning and accomplished programmers alike and can be a learning experience for the novices amongst us.
function dateFormat (date, fstr, utc) {
utc = utc ? 'getUTC' : 'get';
return fstr.replace (/%[YmdHMS]/g, function (m) {
switch (m) {
case '%Y': return date[utc + 'FullYear'] (); // no leading zeros required
case '%m': m = 1 + date[utc + 'Month'] (); break;
case '%d': m = date[utc + 'Date'] (); break;
case '%H': m = date[utc + 'Hours'] (); break;
case '%M': m = date[utc + 'Minutes'] (); break;
case '%S': m = date[utc + 'Seconds'] (); break;
default: return m.slice (1); // unknown code, remove %
}
// add leading zero if required
return ('0' + m).slice (-2);
});
}
/* dateFormat (new Date (), "%Y-%m-%d %H:%M:%S", true) returns
"2012-05-18 05:37:21" */
The only solution works on Ubuntu 12.04:
echo -e "new_password\nnew_password" | (passwd user)
But the second option only works when I change from:
echo "password:name" | chpasswd
To:
echo "user:password" | chpasswd
See explanations in original post: Changing password via a script
On RH systems, MySQL configuration file is located under /etc/my.cnf by default.
Only thing worked for me.
Open the project -> Select your target -> Go to Build Settings -> Search PROVISIONING and delete the selected profiles.
Your script seems incorrect in several places.
Try this
var timetemp = document.getElementsByTagName('input');
for (var i = 0; i < timetemp.length; i++){
if (timetemp[i].value == ""){
alert ('No value');
}
else{
alert (timetemp[i].value);
}
}
Example: http://jsfiddle.net/jasongennaro/FSzT2/
Here's what I changed:
input
s via TagName
. This makes an arrayi
with a var
and then looped through the timetemp
array using the timetemp.length
property.timetemp[i]
to reference each input
in the for statement
For limited set of values matplotlib is fine. But when you have lots of values the tooltip starts to overlap over other data points. But with limited space you can't ignore the values. Hence it's better to zoom out or zoom in.
Using plotly
import plotly.express as px
df = px.data.tips()
df = px.data.gapminder().query("year==2007 and continent=='Americas'")
fig = px.scatter(df, x="gdpPercap", y="lifeExp", text="country", log_x=True, size_max=100, color="lifeExp")
fig.update_traces(textposition='top center')
fig.update_layout(title_text='Life Expectency', title_x=0.5)
fig.show()
ansible -m setup hostname
Only gets the facts gathered by the setup module.
Gilles Cornu posted a template trick to list all variables for a specific host.
Template (later called dump_variables):
HOSTVARS (ANSIBLE GATHERED, group_vars, host_vars) :
{{ hostvars[inventory_hostname] | to_yaml }}
PLAYBOOK VARS:
{{ vars | to_yaml }}
Playbook to use it:
- hosts: all
tasks:
- template:
src: templates/dump_variables
dest: /tmp/ansible_variables
- fetch:
src: /tmp/ansible_variables
dest: "{{inventory_hostname}}_ansible_variables"
After that you have a dump of all variables on every host, and a copy of each text dump file on your local workstation in your tmp folder. If you don't want local copies, you can remove the fetch statement.
This includes gathered facts, host variables and group variables. Therefore you see ansible default variables like group_names, inventory_hostname, ansible_ssh_host and so on.

Same-origin policy
https://en.wikipedia.org/wiki/Same-origin_policy
https://en.wikipedia.org/wiki/Cross-origin_resource_sharing
problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1].
url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts // DASH: contains video or audio stream
Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this
url // direct HTTP link to a video
itag // code specifying the quality
s // signature, security measure to counter downloading
Each URL will be encoded so you will need to decode them. Now the tricky part.
YouTube has at least 3 security levels for their videos
unsecured // as expected, you can download these with just the unencoded URL
s // see below
RTMPE // uses "rtmpe://" protocol, no known method for these
The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.
The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as
AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this
function mo(a) {
a = a.split("");
a = lo.rw(a, 1);
a = lo.rw(a, 32);
a = lo.IC(a, 1);
a = lo.wS(a, 77);
a = lo.IC(a, 3);
a = lo.wS(a, 77);
a = lo.IC(a, 3);
a = lo.wS(a, 44);
return a.join("")
}
This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as
http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js
this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header
Access-Control-Allow-Origin: http://www.youtube.com
and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests
Access-Control-Allow-Origin: *
So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

I would try:
self.wordList = list(wordList)
to force it to make a copy instead of referencing the same object.

I had midnight issues in Word and the below code worked for me
Public Function Pause(NumberOfSeconds As Variant)
' On Error GoTo Error_GoTo
Dim PauseTime, Start
Dim objWord As Word.Document
'PauseTime = 10 ' Set duration in seconds
PauseTime = NumberOfSeconds
Start = Timer ' Set start time.
If Start + PauseTime > 86399 Then 'playing safe hence 86399
Start = 0
Do While Timer > 1
DoEvents ' Yield to other processes.
Loop
End If
Do While Timer < Start + PauseTime
DoEvents ' Yield to other processes.
Loop
End Function
There are two storage areas involved: the stack and the heap.The stack is where the current state of a method call is kept (ie local variables and references), and the heap is where objects are stored. recursion and memory
I gues there are too many keys in the counter
dict that will consume too much memory of the heap region, so the Python runtime will raise a OutOfMemory exception.
To save it, don't create a giant object, e.g. the counter.

I came across this as a regression bug when refactoring code from traditional using
blocks to the new C# 8.0 using declaration style, where the block ends when the variable falls out of scope at the end of the method.
Old style:
//...
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, aesCrypto.CreateDecryptor(), CryptoStreamMode.Write))
{
cs.Write(rawCipherText, 0, rawCipherText.Length);
}
return Encoding.Unicode.GetString(ms.ToArray());
}
New, less indented style:
//...
using MemoryStream ms = new MemoryStream();
using CryptoStream cs = new CryptoStream(ms, aesCrypto.CreateDecryptor(), CryptoStreamMode.Write);
cs.Write(rawCipherText, 0, rawCipherText.Length);
cs.FlushFinalBlock();
return Encoding.Unicode.GetString(ms.ToArray());
With the old style, the using
block for the CryptoStream terminated and the finalizer was called before memory stream gets read in the return
statement, so the CryptoStream was automatically flushed.
With the new style, the memory stream is read before the CryptoStream finalizer gets called, so I had to manually call FlushFinalBlock()
before reading from the memory stream in order to fix this issue. I had to manually flush the final block for both the encrypt and the decrypt methods, when they were written in the new using
style.
If you have a single .java file to compile using command-line , then remove topmost package parts from the code, the compile again, it will work.
This worked for me.
function scroll_to_anchor(anchor_id){
var tag = $("#"+anchor_id+"");
$('html,body').animate({scrollTop: tag.offset().top},'slow');
}
It's called String#start_with?
, not String#startswith
: In Ruby, the names of boolean-ish methods end with ?
and the words in method names are separated with an _
. Not sure where the s
went, personally, I'd prefer String#starts_with?
over the actual String#start_with?
If Java is installed on your 11G then you can do it in a java class and call it from your PL/SQL, but I am not sure that it does not require also a specific grant to call java.
Try this.
public class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
var json = config.Formatters.JsonFormatter;
json.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));
config.Formatters.Remove(config.Formatters.XmlFormatter);
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional , Action =RouteParameter.Optional }
);
}
}
Any method you use, there will always be a loop like in removeAll()
and set()
.
So, I solved my problem like this:
for (int i = 0; i < myList.size(); i++) {
if (myList.get(i).getName().equals(varName)) {
myList.get(i).setEmail(varEmail);
break;
}
}
Where varName = "Doe"
and varEmail = "[email protected]"
.
I hope this help you.
You can notice the properties that cause the circular reference. Then you can do something like:
private Object DeCircular(Object object)
{
// Set properties that cause the circular reference to null
return object
}
I tried the following and it didn't work on my environment:
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory());
But different property worked like a charm:
bindingProvider.getRequestContext().put(JAXWSProperties.SSL_SOCKET_FACTORY, getCustomSocketFactory());
The rest of the code was taken from the first reply.
THIS CAN BE A QUICK FIX FOR ECLIPSE
When I was trying to create array list it gave error that array list cannot be resolved to type and something about "parametrised type are only in level 1.5"
Only I did was I tried to import java.util.ArrayList;
And that error went away.
I had a similar problem, which turned out to be caused by missing double quotes off the table and schema name.
UPDATED: One-liner solution, for random 20 characters (alphanumeric lowercase):
Array.from(Array(20), () => Math.floor(Math.random() * 36).toString(36)).join('');
Or shorter with lodash:
_.times(20, () => _.random(35).toString(36)).join('');
If you want to perform any event on any specific keyboard button press, in that case, you can use @HostListener. For this, you have to import HostListener in your component ts file.
import { HostListener } from '@angular/core';
then use below function anywhere in your component ts file.
@HostListener('document:keyup', ['$event'])
handleDeleteKeyboardEvent(event: KeyboardEvent) {
if(event.key === 'Delete')
{
// remove something...
}
}
Armin's answer is so useful, thank you. #2 is what's most important to know when trying to set up unload events that work in most browsers: you cannot alert() or confirm(), but returning a string will generate a confirm modal.
But I found that even with just returning a string, I had some cross-browser issues specific to Mootools (using version 1.4.5 in this instance). This Mootools-specific implementation worked great in Firefox, but did not result in a confirm popup in Chrome or Safari:
window.addEvent("beforeunload", function() {
return "Are you sure you want to leave this page?";
});
So in order to get my onbeforeonload event to work across browsers, I had to use the JavaScript native call:
window.onbeforeunload = function() {
return "Are you sure you want to leave this page?";
}
Not sure why this is the case, or if it's been fixed in later versions of Mootools.
Pass CultureInfo.InvariantCulture as the second parameter of DateTime, it will return the string as what you want, even a very special format:
DateTime.Now.ToString("dd|MM|yyyy", CultureInfo.InvariantCulture)
will return: 28|02|2014
The command setwd("~/")
should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise "~/"
as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.
As you have tagged the post using RStudio:
You will now have set the folder as your working directory. Use the command getwd()
to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use setwd
with that string as the argument, so that each time you run the script you use the same directory.
For example at the top of my script I would have:
work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)
Why invent wheels yourself while there is a car ready for you? I just find this tools super easy and intuitive to use: Advanced Installer. This one minute video should be enough to impress you. Here is the illustrative user guide.
your break statement should break out of the for (in in 1:n)
.
Personally I am always wary with break statements and double check it by printing to the console to double check that I am in fact breaking out of the right loop. So before you test add the following statement, which will let you know if you break before it reaches the end. However, I have no idea how you are handling the variable n
so I don't know if it would be helpful to you. Make a n
some test value where you know before hand if it is supposed to break out or not before reaching n
.
for (in in 1:n)
{
if (in == n) #add this statement
{
"sorry but the loop did not break"
}
id_novo <- new_table_df$ID[in]
if(id_velho==id_novo)
{
break
}
else if(in == n)
{
sold_df <- rbind(sold_df,old_table_df[out,])
}
}
Don't reinvent the wheel. Use json-framework or something similar.
If you do decide to use json-framework, here's how you would parse a JSON string into an NSDictionary
:
SBJsonParser* parser = [[[SBJsonParser alloc] init] autorelease];
// assuming jsonString is your JSON string...
NSDictionary* myDict = [parser objectWithString:jsonString];
// now you can grab data out of the dictionary using objectForKey or another dictionary method

I was trying to test an extjs application and after sucessfully setting a testingAuthenticationToken this suddenly stopped working with no obvious cause.
I couldn't get the above answers to work so my solution was to skip out this bit of spring in the test environment. I introduced a seam around spring like this:
public class SpringUserAccessor implements UserAccessor
{
@Override
public User getUser()
{
SecurityContext context = SecurityContextHolder.getContext();
Authentication authentication = context.getAuthentication();
return (User) authentication.getPrincipal();
}
}
User is a custom type here.
I'm then wrapping it in a class which just has an option for the test code to switch spring out.
public class CurrentUserAccessor
{
private static UserAccessor _accessor;
public CurrentUserAccessor()
{
_accessor = new SpringUserAccessor();
}
public User getUser()
{
return _accessor.getUser();
}
public static void UseTestingAccessor(User user)
{
_accessor = new TestUserAccessor(user);
}
}
The test version just looks like this:
public class TestUserAccessor implements UserAccessor
{
private static User _user;
public TestUserAccessor(User user)
{
_user = user;
}
@Override
public User getUser()
{
return _user;
}
}
In the calling code I'm still using a proper user loaded from the database:
User user = (User) _userService.loadUserByUsername(username);
CurrentUserAccessor.UseTestingAccessor(user);
Obviously this wont be suitable if you actually need to use the security but I'm running with a no-security setup for the testing deployment. I thought someone else might run into a similar situation. This is a pattern I've used for mocking out static dependencies before. The other alternative is you can maintain the staticness of the wrapper class but I prefer this one as the dependencies of the code are more explicit since you have to pass CurrentUserAccessor into classes where it is required.
-> it works like pointer u don't have to use *
for( list<student>::iterator iter= data.begin(); iter != data.end(); iter++ )
cout<<iter->name; //'iter' not 'it'
Just as reference, you can also use Mysql Variables to save temporary results, e.g.:
SET @v1 := (SELECT ... );
UPDATE ... SET ... WHERE x=@v1;
Sample code to set the rightbutton
on a NavigationBar
.
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
style:UIBarButtonItemStyleDone target:nil action:nil];
UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:@"Title"];
item.rightBarButtonItem = rightButton;
item.hidesBackButton = YES;
[bar pushNavigationItem:item animated:NO];
But normally you would have a NavigationController
, enabling you to write:
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
style:UIBarButtonItemStyleDone target:nil action:nil];
self.navigationItem.rightBarButtonItem = rightButton;
I did subscript capital & bolded V. It works perfectly (although it takes some effort, if it needs to be done repetitively)
Syntax:

Open Notepad.
Type the following lines into it (obviously replace the folders with your ones)
@echo off
rem you could also remove the line above, because it might help you to see what happens
rem /i option is needed to avoid the batch file asking you whether destination folder is a file or a folder
rem /e option is needed to copy also all folders and subfolders
xcopy "c:\New Folder" "c:\Copy of New Folder" /i /e
Save the file as backup.bat (not .txt)
Double click on the file to run it. It will backup the folder and all its contents files/subfolders.
Now if you want the batch file to be run everytime you login in Windows, you should place it in Windows Startup menu. You find it under: Start > All Program > Startup To place the batch file in there either drag it into the Startup menu or RIGH click on the Windows START button and select Explore, go in Programs > Startup, and copy the batch file into there.
To run the batch file everytime the folder is updated you need an application, it can not be done with just a batch file.
If you are open to use third party tools you'd have a look at this one: https://github.com/CircleOfNice/DoctrineRestDriver
This is a completely new way to work with APIs.
First of all you define an entity which is defining the structure of incoming and outcoming data and annotate it with datasources:
/*
* @Entity
* @DataSource\Select("http://www.myApi.com/products/{id}")
* @DataSource\Insert("http://www.myApi.com/products")
* @DataSource\Select("http://www.myApi.com/products/update/{id}")
* @DataSource\Fetch("http://www.myApi.com/products")
* @DataSource\Delete("http://www.myApi.com/products/delete/{id}")
*/
class Product {
private $name;
public function setName($name) {
$this->name = $name;
}
public function getName() {
return $this->name;
}
}
Now it's pretty easy to communicate with the REST API:
$product = new Product();
$product->setName('test');
// sends an API request POST http://www.myApi.com/products ...
$em->persist($product);
$em->flush();
$product->setName('newName');
// sends an API request UPDATE http://www.myApi.com/products/update/1 ...
$em->flush();
Here's a working example that I'm using to implement an autocomplete variation the populates a jqueryui selector (list), but I don't want it to function exactly like the jqueryui autocomplete which does a drop-down menu.
$("#tagFilter").on("change keyup paste", function() {
var filterText = $("#tagFilter").val();
$("#tags").empty();
$.getJSON("http://localhost/cgi-bin/tags.php?term=" + filterText,
function(data) {
var i;
for (i = 0; i < data.length; i++) {
var tag = data[i].value;
$("#tags").append("<li class=\"tag\">" + tag + "</li>");
}
});
});
you can create your own custom event by using diagnostics.Event log class. Open a windows application and on a button click do the following code.
System.Diagnostics.EventLog.CreateEventSource("ApplicationName", "MyNewLog");
"MyNewLog" means the name you want to give to your log in event viewer.

If MVC, you can do:
public async Task<IActionResult> DeleteAll()
{
var list = await _context.YourClass.ToListAsync();
_context.YourClass.RemoveRange(list);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
