Also, this might help finding the actual location the btsnoop_hci.log is being saved:
adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"
I also solved this error by adding useCORS : true,
in my code like -
html2canvas($("#chart-section")[0], {
useCORS : true,
allowTaint : true,
scale : 0.98,
dpi : 500,
width: 1400, height: 900
}).then();
You won't be able to draw images directly from another server into a canvas and then use getImageData
. It's a security issue and the canvas will be considered "tainted".
Would it work for you to save a copy of the image to your server using PHP and then just load the new image? For example, you could send the URL to the PHP script and save it to your server, then return the new filename to your javascript like this:
<?php //The name of this file in this example is imgdata.php
$url=$_GET['url'];
// prevent hackers from uploading PHP scripts and pwning your system
if(!@is_array(getimagesize($url))){
echo "path/to/placeholderImage.png";
exit("wrong file type.");
}
$img = file_get_contents($url);
$fn = substr(strrchr($url, "/"), 1);
file_put_contents($fn,$img);
echo $fn;
?>
You'd use the PHP script with some ajax javascript like this:
xi=new XMLHttpRequest();
xi.open("GET","imgdata.php?url="+yourImageURL,true);
xi.send();
xi.onreadystatechange=function() {
if(xi.readyState==4 && xi.status==200) {
img=new Image;
img.onload=function(){
ctx.drawImage(img, 0, 0, canvas.width, canvas.height);
}
img.src=xi.responseText;
}
}
If you use getImageData
on the canvas after that, it will work fine.
Alternatively, if you don't want to save the whole image, you could pass x & y coordinates to your PHP script and calculate the pixel's rgba value on that side. I think there are good libraries for doing that kind of image processing in PHP.
If you want to use this approach, let me know if you need help implementing it.
edit-1: peeps pointed out that the php script is exposed and allows the internet to potentially use it maliciously. there are a million ways to handle this, one of the simplest being some sort of URL obfuscation... i reckon secure php practices deserves a separate google ;P
edit-2: by popular demand, I've added a check to ensure it is an image and not a php script (from: PHP check if file is an image).
In my case, I was fetching data from database, changing some column values and updating it in database but for updating I was using the same save query which was violating primary key constraints i.e duplicate values for primary key, so I had written a separate query for updating the columns and it solved my problem..!
This is what works me for the current version of retrofit
2.6.2,
First of all, we need to add a Scalars Converter to the list of our Gradle dependencies, which would take care of converting java.lang.String objects to text/plain request bodies,
implementation'com.squareup.retrofit2:converter-scalars:2.6.2'
Then, we need to pass a converter factory to our Retrofit builder. It will later tell Retrofit how to convert the @Body parameter passed to the service.
private val retrofitBuilder: Retrofit.Builder by lazy {
Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
}
Note: In my retrofit builder i have two converters
Gson
andScalars
you can use both of them but to send Json body we need to focusScalars
so if you don't needGson
remove it
Then Retrofit service with a String body parameter.
@Headers("Content-Type: application/json")
@POST("users")
fun saveUser(@Body user: String): Response<MyResponse>
Then create the JSON body
val user = JsonObject()
user.addProperty("id", 001)
user.addProperty("name", "Name")
Call your service
RetrofitService.myApi.saveUser(user.toString())
By using fabric js we can solve this security error issue in IE.
function getBase64FromImageUrl(URL) {
var canvas = new fabric.Canvas('c');
var img = new Image();
img.onload = function() {
var canvas1 = document.createElement("canvas");
canvas1.width = this.width;
canvas1.height = this.height;
var ctx = canvas.getContext('2d');
ctx.drawImage(this, 0, 0);
var dataURL = canvas.toDataURL({format: "png"});
};
img.src = URL;
}
Functions are easy to call inside a select loop, but they don't let you run inserts, updates, deletes, etc. They are only useful for query operations. You need a stored procedure to manipulate the data.
So, the real answer to this question is that you must iterate through the results of a select statement via a "cursor" and call the procedure from within that loop. Here's an example:
DECLARE @myId int;
DECLARE @myName nvarchar(60);
DECLARE myCursor CURSOR FORWARD_ONLY FOR
SELECT Id, Name FROM SomeTable;
OPEN myCursor;
FETCH NEXT FROM myCursor INTO @myId, @myName;
WHILE @@FETCH_STATUS = 0 BEGIN
EXECUTE dbo.myCustomProcedure @myId, @myName;
FETCH NEXT FROM myCursor INTO @myId, @myName;
END;
CLOSE myCursor;
DEALLOCATE myCursor;
Note that @@FETCH_STATUS
is a standard variable which gets updated for you. The rest of the object names here are custom.
Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.
Short answer to your question: Yes there are other stuff included than whats in the list.
What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.
From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.
Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.
Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.
This creates an almost guaranteed unique 32 character key client side, if you want just numbers change the "chars" var.
var d = new Date().valueOf();
var n = d.toString();
var result = '';
var length = 32;
var p = 0;
var chars = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
for (var i = length; i > 0; --i){
result += ((i & 1) && n.charAt(p) ? '<b>' + n.charAt(p) + '</b>' : chars[Math.floor(Math.random() * chars.length)]);
if(i & 1) p++;
};
The task gives you all the goodness of the task API:
Task.ContinueWith
)Note that in both cases you can make your code slightly simpler with method group conversions:
DataInThread = new Thread(ThreadProcedure);
// Or...
Task t = Task.Factory.StartNew(ThreadProcedure);
In PHP >= 5.4.0 there is a new interface for serializing objects to JSON : JsonSerializable
Just implement the interface in your object and define a JsonSerializable
method which will be called when you use json_encode
.
So the solution for PHP >= 5.4.0 should look something like this:
class JsonObject implements JsonSerializable
{
// properties
// function called when encoded with json_encode
public function jsonSerialize()
{
return get_object_vars($this);
}
}
I think you want to specify
-H "Content-Type:text/xml"
with a colon, not an equals.
One way that the Scala community can help ease the fear of programmers new to Scala is to focus on practice and to teach by example--a lot of examples that start small and grow gradually larger. Here are a few sites that take this approach:
After spending some time on these sites, one quickly realizes that Scala and its libraries, though perhaps difficult to design and implement, are not so difficult to use, especially in the common cases.

I prefer to use tuples whenever a tuple feels "natural"; coordinates are a typical example, where the separate objects can stand on their own, e.g. in one-axis only scaling calculations, and the order is important. Note: if I can sort or shuffle the items without an adverse effect to the meaning of the group, then I probably shouldn't use a tuple.
I use dictionaries as a return value only when the grouped objects aren't always the same. Think optional email headers.
For the rest of the cases, where the grouped objects have inherent meaning inside the group or a fully-fledged object with its own methods is needed, I use a class.
If you create a user with the advanced user management (from command line: netplwiz
), then modify the group, remove users, and add iis_users. They will be able to authenticate to your web page, but not the computer.
It all depends how you use Java or C# enums. How you use it will dictate the solution you'll choose in Ruby.
Try the native Set
type, for instance:
>> enum = Set['a', 'b', 'c']
=> #<Set: {"a", "b", "c"}>
>> enum.member? "b"
=> true
>> enum.member? "d"
=> false
>> enum.add? "b"
=> nil
>> enum.add? "d"
=> #<Set: {"a", "b", "c", "d"}>
If you are concerned about the "unterminated character class" case, removing all non-alphanumeric chars would be helpful:
searchstring = searchstring.replace(/[^a-zA-Z 0-9]+/g,'');
Try this example
String[] formats = new String[] {
"yyyy-MM-dd",
"yyyy-MM-dd HH:mm",
"yyyy-MM-dd HH:mmZ",
"yyyy-MM-dd HH:mm:ss.SSSZ",
"yyyy-MM-dd'T'HH:mm:ss.SSSZ",
};
for (String format : formats) {
SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
}

This answer is based on Yann's answer. It will set the aspect ratio for linear or log-log plots. I've used additional information from https://stackoverflow.com/a/16290035/2966723 to test if the axes are log-scale.
def forceAspect(ax,aspect=1):
#aspect is width/height
scale_str = ax.get_yaxis().get_scale()
xmin,xmax = ax.get_xlim()
ymin,ymax = ax.get_ylim()
if scale_str=='linear':
asp = abs((xmax-xmin)/(ymax-ymin))/aspect
elif scale_str=='log':
asp = abs((scipy.log(xmax)-scipy.log(xmin))/(scipy.log(ymax)-scipy.log(ymin)))/aspect
ax.set_aspect(asp)
Obviously you can use any version of log
you want, I've used scipy
, but numpy
or math
should be fine.
I suppose better would be to use re.match() function. here is an example which may help you.

for i in range(len(animals)):
print "The %d animal is at %d and is a %s" % (i+1 ,i, animals[i])

Just checkout the commit you wants your new branch start from and create a new branch

The equivalent is a BIT
field.
In SQL
you use 0
and 1
to set a bit field (just as a yes/no field in Access). In Management Studio it displays as a false/true value (at least in recent versions).
When accessing the database through ASP.NET it will expose the field as a boolean value.
What about /usr/share/dict/words
on any Unix system? How many words are we talking about? Like OED-Unabridged?
Assuming SQL Server:
e.g. if you class special characters as anything NOT alphanumeric:
DECLARE @MyString VARCHAR(100)
SET @MyString = 'adgkjb$'
IF (@MyString LIKE '%[^a-zA-Z0-9]%')
PRINT 'Contains "special" characters'
ELSE
PRINT 'Does not contain "special" characters'
Just add to other characters you don't class as special, inside the square brackets
Just my two cents, but doesn't the following code portably work in C++17?
#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
int main(int argc, char* argv[])
{
std::cout << "Path is " << fs::path(argv[0]).parent_path() << '\n';
}
Seems to work for me on Linux at least.
Based on the previous idea, I now have:
std::filesystem::path prepend_exe_path(const std::string& filename, const std::string& exe_path = "");
With implementation:
fs::path prepend_exe_path(const std::string& filename, const std::string& exe_path)
{
static auto exe_parent_path = fs::path(exe_path).parent_path();
return exe_parent_path / filename;
}
And initialization trick in main()
:
(void) prepend_exe_path("", argv[0]);
Thanks @Sam Redway for the argv[0] idea. And of course, I understand that C++17 was not around for many years when the OP asked the question.
Try putting this HTML snippet into your served document:
<img id="ItemPreview" src="">
Then, on JavaScript side, you can dynamically modify image's src
attribute with so-called Data URL.
document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;
Alternatively, using jQuery:
$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);
This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..."
part) in the URL accordingly.

It's actually quite simple. When you installed it, you must have done it using some .exe file (I am assuming). Just run that .exe again, and then there will be options to modify Python. Just select the "Complete Uninstall" option, and the EXE will completely wipe out python for you.
Also, you might have to checkbox the "Remove Python from PATH". By default it is selected, but you may as well check it to be sure :)

getAbsolutePath(){
[[ -d $1 ]] && { cd "$1"; echo "$(pwd -P)"; } ||
{ cd "$(dirname "$1")" || exit 1; echo "$(pwd -P)/$(basename "$1")"; }
}
There is a correct version on here but I thought it would be nice to add a little fault tolerance in case they have a trailing comma as well as make it so you could use it not as a function but as part of a larger piece of code. Just in case you're only using it once time and don't need a function. This is also for integers (which is what I needed it for) so you might have to change your data types.
DECLARE @StringToSeperate VARCHAR(10)
SET @StringToSeperate = '1,2,5'
--SELECT @StringToSeperate IDs INTO #Test
DROP TABLE #IDs
CREATE TABLE #IDs (ID int)
DECLARE @CommaSeperatedValue NVARCHAR(255) = ''
DECLARE @Position INT = LEN(@StringToSeperate)
--Add Each Value
WHILE CHARINDEX(',', @StringToSeperate) > 0
BEGIN
SELECT @Position = CHARINDEX(',', @StringToSeperate)
SELECT @CommaSeperatedValue = SUBSTRING(@StringToSeperate, 1, @Position-1)
INSERT INTO #IDs
SELECT @CommaSeperatedValue
SELECT @StringToSeperate = SUBSTRING(@StringToSeperate, @Position+1, LEN(@StringToSeperate)-@Position)
END
--Add Last Value
IF (LEN(LTRIM(RTRIM(@StringToSeperate)))>0)
BEGIN
INSERT INTO #IDs
SELECT SUBSTRING(@StringToSeperate, 1, @Position)
END
SELECT * FROM #IDs
Another nice thing about @HostBinding
is that you can combine it with @Input
if your binding relies directly on an input, eg:
@HostBinding('class.fixed-thing')
@Input()

You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.

You are missing a step. You need to log / store the values on your server (mailgun is a client). Then you need to retrieve those values on your server (your pc with your web browser will be a client). These will be two totally different aspx files (or the same one with different parameters).
aspx page 1 (the one that mailgun has):
var val = Request.Form["recipient"];
var file = new File(filename);
file.write(val);
close(file);
aspx page 2:
var contents = "";
if (File.exists(filename))
var file = File.open(filename);
contents = file.readtoend();
file.close()
Request.write(contents);
You have four options
Finite differences require no external tools but are prone to numerical error and, if you're in a multivariate situation, can take a while.
Symbolic differentiation is ideal if your problem is simple enough. Symbolic methods are getting quite robust these days. SymPy is an excellent project for this that integrates well with NumPy. Look at the autowrap or lambdify functions or check out Jensen's blogpost about a similar question.
Automatic derivatives are very cool, aren't prone to numeric errors, but do require some additional libraries (google for this, there are a few good options). This is the most robust but also the most sophisticated/difficult to set up choice. If you're fine restricting yourself to numpy
syntax then Theano might be a good choice.
Here is an example using SymPy
In [1]: from sympy import *
In [2]: import numpy as np
In [3]: x = Symbol('x')
In [4]: y = x**2 + 1
In [5]: yprime = y.diff(x)
In [6]: yprime
Out[6]: 2·x
In [7]: f = lambdify(x, yprime, 'numpy')
In [8]: f(np.ones(5))
Out[8]: [ 2. 2. 2. 2. 2.]

There are some subtle differences that mean you can use ViewData and ViewBag in slightly different ways from the view. One advantage is outlined in this post http://weblogs.asp.net/hajan/archive/2010/12/11/viewbag-dynamic-in-asp-net-mvc-3-rc-2.aspx and shows that casting can be avoided in the example by using the ViewBag instead of ViewData.
If it's a list of string, just use the c()

$b
[1] "dick"
$c
[1] "harry"
R> class(LL)
[1] "list"
R>
That works on vectors too, so do I get the bonus points?

newlist <- list(oldlist, list(someobj))
In general, R types can make it hard to have one and just one idiom for all types and uses.
A more concise, elegant, and secure answer: add “?enablejsapi=1” to the end of the video URL, then construct and stringify an ordinary object representing the pause command:
const YouTube_pause_video_command_JSON = JSON.stringify(Object.create(null, {
"event": {
"value": "command",
"enumerable": true
},
"func": {
"value": "pauseVideo",
"enumerable": true
}
}));
Use the Window.postMessage
method to send the resulting JSON string to the embedded video document:
// |iframe_element| is defined elsewhere.
const video_URL = iframe_element.getAttributeNS(null, "src");
iframe_element.contentWindow.postMessage(YouTube_pause_video_command_JSON, video_URL);
Make sure you specify the video URL for the Window.postMessage
method’s targetOrigin
argument to ensure that your messages won’t be sent to any unintended recipient.

Disabled elements "eat" clicks in some browsers - they neither respond to them, nor allow them to be captured by event handlers anywhere on either the element or any of its containers.
IMHO the simplest, cleanest way to "fix" this (if you do in fact need to capture clicks on disabled elements like the OP does) is just to add the following CSS to your page:
input[disabled] {pointer-events:none}
This will make any clicks on a disabled input fall through to the parent element, where you can capture them normally. (If you have several disabled inputs, you might want to put each into an individual container of its own, if they aren't already laid out that way - an extra <span>
or a <div>
, say - just to make it easy to distinguish which disabled input was clicked).
The downside is that this trick unfortunately won't works for older browsers that don't support the pointer-events
CSS property. (It should work from IE 11, FF v3.6, Chrome v4): caniuse.com/#search=pointer-events
If you need to support older browsers, you'll need to use one of the other answers!

Have a look at the ReadAsset.java from API samples that come with the SDK.
try {
InputStream is = getAssets().open("read_asset.txt");
// We guarantee that the available method returns the total
// size of the asset... of course, this does mean that a single
// asset can't be more than 2 gigs.
int size = is.available();
// Read the entire asset into a local byte buffer.
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
// Convert the buffer into a string.
String text = new String(buffer);
// Finally stick the string into the text view.
TextView tv = (TextView)findViewById(R.id.text);
tv.setText(text);
} catch (IOException e) {
// Should never happen!
throw new RuntimeException(e);

I know this is not a solution for OP, but since I'm sure there are many other use cases here, I thought I would share.
I've had problems with all the code examples in these answers but then I found : http://www.robotronic.de/runasspcEn.html
It not only allows you to run as admin, it checks the file to make sure it has not been tampered with and stores the needed information securely. I'll admit it's not the most obvious tool to figure out how to use but for those of us writing code it should be simple enough.
Open the sql file and comment out the line that tries to create the existing database.
Version 7 of Angular has been released Official Angular blog link. Visit official angular update guide https://update.angular.io for detailed information. These steps will work for basic angular 6 apps using Angular Material.
ng update @angular/cli
ng update @angular/core
ng update @angular/material
Version 6 of Angular has been released Official Angular blog link. I have mentioned general upgrade steps below, but before and after the update you need to make changes in your code to make it workable in v6, for that detailed information visit official website https://update.angular.io .
Upgrade Steps (largely taken from the official Angular Update Guide for a basic Angular app using Angular Material):
Make sure NodeJS version is 8.9+ if not update it.
Update Angular cli globally and locally, and migrate the old configuration .angular-cli.json to the new angular.json format by running the following:
npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli
Update all of your Angular framework packages to v6,and the correct version of RxJS and TypeScript by running the following:
ng update @angular/core
Update Angular Material to the latest version by running the following:
ng update @angular/material
RxJS v6 has major changes from v5, v6 brings backwards compatibility package rxjs-compat that will keep your applications working, but you should refactor TypeScript code so that it doesn't depend on rxjs-compat. To refactor TypeScript code run following:
npm install -g rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json
Note: Once all of your dependencies have updated to RxJS 6, remove rxjs- compat as it increases bundle size. please see this RxJS Upgrade Guide for more info.
npm uninstall rxjs-compat
Done run ng serve
to check it.
If you get errors in build refer https://update.angular.io for detailed info.
Upgrade rxjs to 6.0.0-beta.0, please see this RxJS Upgrade Guide for more info. RxJS v6 has breaking change hence first make your code compatible to latest RxJS version.
Update NodeJS version to 8.9+ (this is required by angular cli 6 version)
Update Angular cli global package to next version.
npm uninstall -g @angular/cli
npm cache verify
if npm version is < 5 then use npm cache clean
npm install -g @angular/cli@next
Change angular packages versions in package.json file to ^6.0.0-rc.5

}
Next update Angular cli local package to next version and install above mentioned packages.
rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows
Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
npm install --save-dev @angular/cli@next
npm install
The Angular CLI configuration format has been changed from angular cli 6.0.0-rc.2 version, and your existing configuration can be updated automatically by running the following command. It will remove old config file .angular-cli.json and will write new angular.json file.
ng update @angular/cli --migrate-only --from=1.7.4
Note :- If you get following error "The Angular Compiler requires TypeScript >=2.7.2 and <2.8.0 but 2.8.3 was found instead". run following command :
npm install [email protected]
I'd go with the multiple resource files. It shouldn't be that hard to configure. In fact I recently answered a similar question on setting a global language based resource files in conjunction with form language resource files.
Localization in Visual Studio 2008
I would consider that the best approach at least for WinForm development.
This expression will check if the first letter to be alphabetic and the remaining characters to be alphanumeric or any of the following special characters: @,#,%,&,
^[A-Za-z][A-Za-z0-9@#%&\*]*$
Unless you enabled innodb_file_per_table
option, InnoDB
keeps all data in one file, usually called ibdata1
.
Check the size of that file and check you have enough disk space in the drive it resides on.
The answer comes from the first paragraph of the documentation check if the results is greater than -1, not if it's true or false.
The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0.
Because JavaScript treats 0 as loosely equal to false (i.e. 0 == false, but 0 !== false), if we're checking for the presence of value within array, we need to check if it's not equal to (or greater than) -1.
If anyone is getting this error using Nginx, try adding the following to your server config:
server {
listen 443 ssl;
...
}
The issue stems from Nginx serving an HTTP server to a client expecting HTTPS on whatever port you're listening on. When you specify ssl
in the listen
directive, you clear this up on the server side.
If you know the white space is only due to spaces, you can use:
$string = str_replace(' ','',$string);
But if it could be due to space, tab...you can use:
$string = preg_replace('/\s+/','',$string);
Angular and Django Rest Framework.
I encountered similar error while making post request to my DRF api. It happened that all I was missing was trailing slash for endpoint.
The problem is that the change event fires only when focus is moved away from the input (e.g. someone clicks off the input or tabs out of it). Try using keyup instead:
$(document).ready(function() {
$(':input[type="submit"]').prop('disabled', true);
$('input[type="text"]').keyup(function() {
if($(this).val() != '') {
$(':input[type="submit"]').prop('disabled', false);
}
});
});
SELECT [ReportId],
SUBSTRING(d.EmailList,1, LEN(d.EmailList) - 1) EmailList
FROM
(
SELECT DISTINCT [ReportId]
FROM Table1
) a
CROSS APPLY
(
SELECT [Email] + ', '
FROM Table1 AS B
WHERE A.[ReportId] = B.[ReportId]
FOR XML PATH('')
) D (EmailList)
This is due to a bug in Webkit.
You can work around the Webkit bug using createEvent('Event')
rather than createEvent('KeyboardEvent')
, and then assigning the keyCode
property. See this answer and this example.
using System.Linq; //SequenceEqual
byte[] ByteArray1 = null;
byte[] ByteArray2 = null;
ByteArray1 = MyFunct1();
ByteArray2 = MyFunct2();
if (ByteArray1.SequenceEqual<byte>(ByteArray2) == true)
{
MessageBox.Show("Match");
}
else
{
MessageBox.Show("Don't match");
}
My team and I ran into this error, unable to update local ref, when doing a pull in SourceTree.
Update 2020: Per @Edward Yang's answer below, @bryan's comment on this answer, and this question/answer you may need to run both
git gc --prune=now
andgit remote prune origin
. Running only the former has always worked for me but based on ppl's responses I think both are necessary to address different causes of the error.
We used:
git gc --prune=now
This removes any duplicate reference objects which should fix the issue.
Here are a few links where you can learn more about git references and pruning :
What is your output when you do java -version
? This will tell you what version the running JVM is.
The Unsupported major.minor version 51.0 error could mean:
Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor
error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)
See: http://www.java.com/en/download/manual.jsp (7 Update 25 )
and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)
for the latest version of the JRE and JDK respectively.
EDIT:
Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.
Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.
FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :
strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"
I experienced this issue when calling my web api endpoint and solved it.
In my case it was an issue in the way the client was encoding the body content. I was not specifying the encoding or media type. Specifying them solved it.
Not specifying encoding type, caused 415 error:
var content = new StringContent(postData);
httpClient.PostAsync(uri, content);
Specifying the encoding and media type, success:
var content = new StringContent(postData, Encoding.UTF8, "application/json");
httpClient.PostAsync(uri, content);
Alternatively, if you just want to convert one particular row to uppercase, use the code below:
df[[1]] <- toupper(df[[1]])
PHP has a built in function called bool chmod(string $filename, int $mode )
private function writeFileContent($file, $content){
$fp = fopen($file, 'w');
fwrite($fp, $content);
fclose($fp);
chmod($file, 0777); //changed to add the zero
return true;
}
-webkit-box-shadow: 0 3px 5px -3px #000;
-moz-box-shadow: 0 3px 5px -3px #000;

"/" is integer division in python 2 so it is going to round to a whole number. If you would like a decimal returned, just change the type of one of the inputs to float:
float(20)/15 #1.33333333
Use the format()
function with a '02x'
format.
>>> format(255, '02x')
'ff'
>>> format(2, '02x')
'02'
The 02
part tells format()
to use at least 2 digits and to use zeros to pad it to length, x
means lower-case hexadecimal.
The Format Specification Mini Language also gives you X
for uppercase hex output, and you can prefix the field width with #
to include a 0x
or 0X
prefix (depending on wether you used x
or X
as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:
>>> format(255, '02X')
'FF'
>>> format(255, '#04x')
'0xff'
>>> format(255, '#04X')
'0XFF'
Some process is using this port, so you can change the port that is used by xampp, to be able to use it. For this job you have to do this:
1- Open httpd-ssl.conf in xampp\apache\conf\extra
2- Look for the line containing Listen 443
3- Change port number to anything you want. I use 4430. ex. Listen 4430.
4- Replace every 443 strings in that file with 4430.
5- Save the file.
While other answers nicely described all differences between C++ casts, I would like to add a short note why you should not use C-style casts (Type) var
and Type(var)
.
For C++ beginners C-style casts look like being the superset operation over C++ casts (static_cast<>(), dynamic_cast<>(), const_cast<>(), reinterpret_cast<>()) and someone could prefer them over the C++ casts. In fact C-style cast is the superset and shorter to write.
The main problem of C-style casts is that they hide developer real intention of the cast. The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<>() and dynamic_cast<>() to potentially dangerous casts like const_cast<>(), where const modifier can be removed so the const variables can be modified and reinterpret_cast<>() that can even reinterpret integer values to pointers.
Here is the sample.
int a=rand(); // Random number.
int* pa1=reinterpret_cast<int*>(a); // OK. Here developer clearly expressed he wanted to do this potentially dangerous operation.
int* pa2=static_cast<int*>(a); // Compiler error.
int* pa3=dynamic_cast<int*>(a); // Compiler error.
int* pa4=(int*) a; // OK. C-style cast can do such cast. The question is if it was intentional or developer just did some typo.
*pa4=5; // Program crashes.
The main reason why C++ casts were added to the language was to allow a developer to clarify his intentions - why he is going to do that cast. By using C-style casts which are perfectly valid in C++ you are making your code less readable and more error prone especially for other developers who didn't create your code. So to make your code more readable and explicit you should always prefer C++ casts over C-style casts.
Here is a short quote from Bjarne Stroustrup's (the author of C++) book The C++ Programming Language 4th edition - page 302.
This C-style cast is far more dangerous than the named conversion operators because the notation is harder to spot in a large program and the kind of conversion intended by the programmer is not explicit.
I always thought of it as the oldest software I have had to install. The total app used a web server, a database server, and an application server. The web server being the middleware between the data and the app.
Of C, A & P (Consistency, Availability & Partition tolerance) which 2 are more important to you? Quick reference, the Visual Guide To NoSQL Systems
A blog post, Cassandra vs MongoDB vs CouchDB vs Redis vs Riak vs HBase vs Membase vs Neo4j comparison has 'Best used' scenarios for each NoSQL database compared. Quoting the link,
A recent (Feb 2012) and more comprehensive comparison by Riyad Kalla,
A blog post (Oct 2011) by someone who tried both, A MongoDB Guy Learns CouchDB commented on the CouchDB's paging being not as useful.
A dated (Jun 2009) benchmark by Kristina Chodorow (part of team behind MongoDB),
I'd go for MongoDB.
Hope it helps.
For .Net Core in Visual Studio 2019 try this. see VS suggestion
It worked for me, hope it'll work for you as well.
A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.
A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.
By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!
If only the incoming stream stalls for more than a millisecond you are running into a timeout.
If you're going to compile a 64bit version(x86_64) of php use: /usr/lib64/
For architectures (i386 ... i686) use /usr/lib/
I recommend compiling php to the same architecture as apache. As you're using a 64bit linux i asume your apache is also compiled for x86_64.
Sure you can; it's called a dictionary:
d = {}
for x in range(1, 10):
d["string{0}".format(x)] = "Hello"
>>> d["string5"]
'Hello'
>>> d
{'string1': 'Hello',
'string2': 'Hello',
'string3': 'Hello',
'string4': 'Hello',
'string5': 'Hello',
'string6': 'Hello',
'string7': 'Hello',
'string8': 'Hello',
'string9': 'Hello'}
I said this somewhat tongue in check, but really the best way to associate one value with another value is a dictionary. That is what it was designed for!
Simple, use array_intersect()
instead:
$result = array_intersect($array1, $array2);

Unlike in some laguages, empty
is not a keyword in Python. Python lists are constructed form the ground up, so if element i
has a value, then element i-1
has a value, for all i > 0
.
To do an equality check, you usually use either the ==
comparison operator.
>>> my_list = ["asdf", 0, 42, '', None, True, "LOLOL"]
>>> my_list[0] == "asdf"
True
>>> my_list[4] is None
True
>>> my_list[2] == "the universe"
False
>>> my_list[3]
""
>>> my_list[3] == ""
True
Here's a link to the strip
method: your comment indicates to me that you may have some strange file parsing error going on, so make sure you're stripping off newlines and extraneous whitespace before you expect an empty line.
there are actually industry standards for widths (well according to yahoo at least). Their supported widths are 750, 950, 974, 100%
There are advantages of these widths for their predefined grids (column layouts) which work well with standard dimensions for advertisements if you were to include any.
Interesting talk too worth watching.

value_counts()
is now a DataFrame method since pandas 1.1.0
https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.value_counts.html
For Windows:
Here I'm Converting all the (.mp4) files to (.mp3) files.
Just open cmd, goto the desired folder and type the command.
Shortcut: (optional)
1. Goto the folder where your (.mp4) files are present
2. Press Shift and Left click and Choose "Open PowerShell Window Here"
or "Open Command Prompt Window Here"
3. Type "cmd" [NOTE: Skip this step if it directly opens cmd instead of PowerShell]
4. Run the command
for %i in (*.mp4) do ffmpeg -i "%i" "%~ni.mp3"
If you want to put this into a batch file on Windows 10, you need to use %%i.
Here is short example of how serialization works. I was also learning about the same and I found two links useful. What Serialization is and how it can be done in .NET.
A sample program explaining serialization
If you don't understand the above program a much simple program with explanation is given here.
.done()
terminates the promise chain, making sure nothing else can attach further steps. This means that the jQuery promise implementation can throw any unhandled exception, since no one can possible handle it using .fail()
.
In practical terms, if you do not plan to attach more steps to a promise, you should use .done()
. For more details see why promises need to be done
Simplest solution, if you want to insert (an element or array) after a certain key:
function array_splice_after_key($array, $key, $array_to_insert)
{
$key_pos = array_search($key, array_keys($array));
if($key_pos !== false){
$key_pos++;
$second_array = array_splice($array, $key_pos);
$array = array_merge($array, $array_to_insert, $second_array);
}
return $array;
}
So, if you have:
$array = [
'one' => 1,
'three' => 3
];
$array_to_insert = ['two' => 2];
And execute:
$result_array = array_splice_after_key($array, 'one', $array_to_insert);
You'll have:
Array (
['one'] => 1
['two'] => 2
['three'] => 3
)
To use cache-control in HTML, you use the meta tag, e.g.
<meta http-equiv="Cache-control" content="public">
The value in the content field is defined as one of the four values below.
Some information on the Cache-Control
header is as follows
HTTP 1.1. Allowed values = PUBLIC | PRIVATE | NO-CACHE | NO-STORE.
Public - may be cached in public shared caches.
Private - may only be cached in private cache.
No-Cache - may not be cached.
No-Store - may be cached but not archived.The directive CACHE-CONTROL:NO-CACHE indicates cached information should not be used and instead requests should be forwarded to the origin server. This directive has the same semantics as the PRAGMA:NO-CACHE.
Clients SHOULD include both PRAGMA: NO-CACHE and CACHE-CONTROL: NO-CACHE when a no-cache request is sent to a server not known to be HTTP/1.1 compliant. Also see EXPIRES.
Note: It may be better to specify cache commands in HTTP than in META statements, where they can influence more than the browser, but proxies and other intermediaries that may cache information.
For me: Converting timestamps coming from API to a valid date :

I have also seen this error when trying to use complex INDIRECT() formulas on the sheet that is being imported. I noticed this because this was the only difference between two workbooks where one was importing and the other wasn't. Both were 2007+ .XLSX files, and the 12.0 engine was installed.

It is my solution for the same problem
You have so many choices, how could you be confused :-)? The main controls are:
# \pset format
# \H
# \x
# \pset pager off
Each has options and interactions with the others. The most automatic options are:
# \x off;\pset format wrapped
# \x auto
The newer "\x auto" option switches to line-by-line display only "if needed".

If you want to print the picture using imshow() you also execute plt.show()
I know I'd selected the anwer by menuka devinda but looking at the comments below it I concurred and tried to come up with a better solution. I managed to come up with this and in my opinion it's a much more elegant solution:

}
Thanks to everyone who offered an answer, your answer didn't go unnoticed. If you still got any other ideas feel free to add your own answer to this question.
Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.
Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe
, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.
Since the FragmentManager will take care of restoring your Fragments for you as soon as the onResume() method is called I have the fragment call out to the activity and add itself to a list. In my instance I am storing all of this in my PagerAdapter implementation. Each fragment knows it's position because it is added to the fragment arguments on creation. Now whenever I need to manipulate a fragment at a specific index all I have to do is use the list from my adapter.
The following is an example of an Adapter for a custom ViewPager that will grow the fragment as it moves into focus, and scale it down as it moves out of focus. Besides the Adapter and Fragment classes I have here all you need is for the parent activity to be able to reference the adapter variable and you are set.

AssertJ provides an excellent feature in extracting()
: you can pass Function
s to extract fields. It provides a check at compile time.
You could also assert the size first easily.
It would give :
import static org.assertj.core.api.Assertions;
Assertions.assertThat(myClass.getMyItems())
.hasSize(2)
.extracting(MyItem::getName)
.containsExactlyInAnyOrder("foo", "bar");
containsExactlyInAnyOrder()
asserts that the list contains only these values whatever the order.
To assert that the list contains these values whatever the order but may also contain other values use contains()
:
.contains("foo", "bar");
As a side note : to assert multiple fields from elements of a List
, with AssertJ we do that by wrapping expected values for each element into a tuple()
function :
import static org.assertj.core.api.Assertions;
import static org.assertj.core.groups.Tuple;
Assertions.assertThat(myClass.getMyItems())
.hasSize(2)
.extracting(MyItem::getName, MyItem::getOtherValue)
.containsExactlyInAnyOrder(
tuple("foo", "OtherValueFoo"),
tuple("bar", "OtherValueBar")
);
This will do it I think:
svn diff -r 22334:HEAD --summarize <url of the branch>
Install this nuget package from Microsoft System.Net.Http.Json
. It contains extension methods.
Then add using System.Net.Http.Json
Now, you'll be able to see these methods:
So you can now do this:

I've got a solution that counts the bits in O(Number of 1's)
time:
bitcount(n):
count = 0
while n > 0:
count = count + 1
n = n & (n-1)
return count
In worst case (when the number is 2^n - 1, all 1's in binary) it will check every bit.
Edit: Just found a very nice constant-time, constant memory algorithm for bitcount. Here it is, written in C:
int BitCount(unsigned int u)
{
unsigned int uCount;
uCount = u - ((u >> 1) & 033333333333) - ((u >> 2) & 011111111111);
return ((uCount + (uCount >> 3)) & 030707070707) % 63;
}
You can find proof of its correctness here.
@sedit was on the right path, but it's a bit awkward to define a variable.
The way to do this in bash is to put a dollar sign in front of your single quoted string.
$ echo -e '1\n2\n3'
1
2
3
$ echo -e '1\n2\n3' | sed 's/.*/\t&/g'
t1
t2
t3
$ echo -e '1\n2\n3' | sed $'s/.*/\t&/g'
1
2
3
If your string needs to include variable expansion, you can put quoted strings together like so:
$ timestamp=$(date +%s)
$ echo -e '1\n2\n3' | sed "s/.*/$timestamp"$'\t&/g'
1491237958 1
1491237958 2
1491237958 3
In bash $'string'
causes "ANSI-C expansion". And that is what most of us expect when we use things like \t
, \r
, \n
, etc. From: https://www.gnu.org/software/bash/manual/html_node/ANSI_002dC-Quoting.html#ANSI_002dC-Quoting
Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard. Backslash escape sequences, if present, are decoded...
The expanded result is single-quoted, as if the dollar sign had not been present.
I personally think most efforts to avoid bash are silly because avoiding bashisms does NOT* make your code portable. (Your code will be less brittle if you shebang it to bash -eu
than if you try to avoid bash and use sh
[unless you are an absolute POSIX ninja].) But rather than have a religious argument about that, I'll just give you the BEST* answer.
$ echo -e '1\n2\n3' | sed "s/.*/$(printf '\t')&/g"

* BEST answer? Yes, because one example of what most anti-bash shell scripters would do wrong in their code is use echo '\t'
as in @robrecord's answer. That will work for GNU echo, but not BSD echo. That is explained by The Open Group at http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html#tag_20_37_16 And this is an example of why trying to avoid bashisms usually fail.
After Your Insert Statement you need to add this. And Make sure about the table name where data is inserting.You will get current row no where row affected just now by your insert statement.
IDENT_CURRENT('tableName')
There is no method call size()
with array
. you can use array.length
Use xsd:include brings all declarations and definitions of an external schema document into the current schema.

I have quite complex WCF web service and I've tried a few different tools, but in most cases I couldn't connect to my web service. Finally I've used this one:
This is only one tool which generetes classes that works without ANY changes!
$request = Request::createFromGlobals();
$getParameter = $request->get('getParameter');
You've to do that in your application layer. If you're using an ORM, it could use annotations (or something similar) to pull references that exist in other collections. I only have worked with Morphia, and the @Reference
annotation fetches the referenced entity when queried, so I am able to avoid doing it myself in the code.
It sounds like what you want is a User who has many Questions.
The Question has many Answers, one of which is the User's Choice.
Is this what you are after?
I would model something like that along these lines:
class User
has_many :questions
end
class Question
belongs_to :user
has_many :answers
has_one :choice, :class_name => "Answer"
validates_inclusion_of :choice, :in => lambda { answers }
end
class Answer
belongs_to :question
end

{
thread1.Start();
//Alternatively, you could pass some object
//in such as Start(someObject);
//With apprioriate locking, or protocol where
//no other threads access the object until
//an event signals when the thread is complete,
//any other class with a reference to the object
//would be able to access that data.
//But instead, I'm going to use AsyncCompletedEventArgs
//in an event that signals completion
}
void thread1_Thread1Completed(object sender, AsyncCompletedEventArgs e)
{
if (this.InvokeRequired)
{//marshal the call if we are not on the GUI thread
BeginInvoke(new AsyncCompletedEventHandler(thread1_Thread1Completed),
new object[] { sender, e });
}
else
{
//display error if error occurred
//if no error occurred, process data
if (e.Error == null)
{//then success
MessageBox.Show("Worker thread completed successfully");
DataYouWantToReturn someData = e.UserState as DataYouWantToReturn;
MessageBox.Show("Your data my lord: " + someData.someProperty);
}
else//error
{
MessageBox.Show("The following error occurred:" + Environment.NewLine + e.Error.ToString());
}
}
}

Add a min
attribute
<input type="number" min="0">
_x000D_
to make it simple, just add a class="form-inline"
before the input.
example:
<div class="col-md-4 form-inline"> //add the class here...
<label>Lot Size:</label>
<input type="text" value="" name="" class="form-control" >
</div>
UPDATE:
All of the above answers won't work for the repeated values, @BenBolker's answer using duplicated()
predicate solves this:
full_vector[!full_vector %in% searched_vector | duplicated(full_vector)]
Original Answer: here I write a little function for this:
exclude_val<-function(full_vector,searched_vector){
found=c()
for(i in full_vector){
if(any(is.element(searched_vector,i))){
searched_vector[(which(searched_vector==i))[1]]=NA
}
else{
found=c(found,i)
}
}
return(found)
}
so, let's say full_vector=c(1,2,3,4,1)
and searched_vector=c(1,2,3)
.
exclude_val(full_vector,searched_vector)
will return (4,1), however above answers will return just (4)
.

Here's a short PowerShell script to do what you probably expect:
$sourceNugetExe = "https://dist.nuget.org/win-x86-commandline/latest/nuget.exe"
$targetNugetExe = "$rootPath\nuget.exe"
Invoke-WebRequest $sourceNugetExe -OutFile $targetNugetExe
Set-Alias nuget $targetNugetExe -Scope Global -Verbose
Note that Invoke-WebRequest
cmdlet arrived with PowerShell v3.0. This article gives the idea.
Turns out for me this error was actually telling the truth - I was trying to resize a Null image, which was usually the 'last' frame of a video file, so the assertion was valid.
Now I have an extra step before attempting the resize operation, which is to do the assertion myself:
def getSizedFrame(width, height):
"""Function to return an image with the size I want"""
s, img = self.cam.read()
# Only process valid image frames
if s:
img = cv2.resize(img, (width, height), interpolation = cv2.INTER_AREA)
return s, img
Now I don't see the error.
Blowfish isn't better than MD5 or SHA512, as they serve different purposes. MD5 and SHA512 are hashing algorithms, Blowfish is an encryption algorithm. Two entirely different cryptographic functions.
You want to save it as a file?

... and then read:
myArray = np.load(open('array.npy', 'rb'))
Since it sounds like you already know what format the byte[] array is in (e.g. RGB, ARGB, BGR etc.) you might be able to use BufferedImage.setRGB(...), or a combination of BufferedImage.getRaster() and WritableRaster.setPixels(...) or WritableRaster.setSamples(...). Unforunately both of these methods require you transform your byte[] into one of int[], float[] or double[] depending on the image format.
You should use a delegate type and specify that as your command parameter. You could use one of the built in delegate types - Action
and Func
.
In your case, it looks like your delegate takes two parameters, and returns a result, so you could use Func
:
List<IJob> GetJobs(Func<FullTimeJob, Student, FullTimeJob> projection)
You could then call your GetJobs
method passing in a delegate instance. This could be a method which matches that signature, an anonymous delegate, or a lambda expression.
P.S. You should use PascalCase for method names - GetJobs
, not getJobs
.
You can make use of location service available in @angular/common and via this below code you can get the location or current URL
import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';

@Component({
selector: 'app-top-nav',
templateUrl: './top-nav.component.html',
styleUrls: ['./top-nav.component.scss']
})
export class TopNavComponent implements OnInit {
route: string;
constructor(location: Location, router: Router) {
router.events.subscribe((val) => {
if(location.path() != ''){
this.route = location.path();
} else {
this.route = 'Home'
}
});
}
ngOnInit() {
}
}
here is the reference link from where I have copied thing to get location for my project. https://github.com/elliotforbes/angular-2-admin/blob/master/src/app/common/top-nav/top-nav.component.ts
A byte is 8 bits (binary data).
A byte array is an array of bytes (tautology FTW!).
You could use a byte array to store a collection of binary data, for example, the contents of a file. The downside to this is that the entire file contents must be loaded into memory.
For large amounts of binary data, it would be better to use a streaming data type if your language supports it.

the disable attribute only has one parameter. if you want to reenable it you have to remove the whole thing, not just change the value.
Something quick and dirty:
<script type='text/javascript'>
function del_tr(remtr)
{
while((remtr.nodeName.toLowerCase())!='tr')
remtr = remtr.parentNode;
remtr.parentNode.removeChild(remtr);
}
function del_id(id)
{
del_tr(document.getElementById(id));
}
</script>
if you place
<a href='' onclick='del_tr(this);return false;'>x</a>
anywhere within the row you want to delete, than its even working without any ids
Across the internet, people have noticed that setting config.enterMode to CKEDITOR.ENTER_BR removes the wrapping paragraph tags from CKEditor. It's worth noting that the setting changes the behavior of the enter key to insert line breaks rather than paragraphs, which is not desirable.
See: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.enterMode "It is recommended to use the CKEDITOR.ENTER_P setting because of its semantic value and correctness."
However, the setting that is designed to remove that initial paragraph, config.autoParagraph, isn't advisable either, as it introduces "unpredictable usability issues" because the editor really wants a top-level block element.
See: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph
The magic happens on wysiwygarea/plugin.js, line 410, where the editor selects the default block element based on config.enterMode. A config option to change the default block element would allow us to start with a div, but we'd continue getting more divs with every enter press, unless we changed the paragraph format via the menu.
See: http://docs.cksource.com/ckeditor_api/symbols/src/plugins_wysiwygarea_plugin.js.html
It would be possible to remove the wrapping paragraph tag with post-processing (either on the server or in CKEditor's getData event), but that leads us into the same problem as disabling autoParagraph: there's no top-level block.
I would rather say that there's not a good solution, but rather a handful of half-solutions, than to accept changing config.enterMode as the canonical solution.
Uncaught TypeError: undefined is not a function example_app.js:7
This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined
.
So what's on example_app.js
line 7? Looks like this:
var tasks = new ExampleApp.Collections.Tasks(data.tasks);
There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks
is undefined
.
So lets look at where that is declared:
var Tasks = Backbone.Collection.extend({
model: Task,
url: '/tasks'
});
If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks
. But you never add it to the ExampleApp.Collections
object, a place you later expect it to be.
Change that to this, and I bet you'd be good.
ExampleApp.Collections.Tasks = Backbone.Collection.extend({
model: Task,
url: '/tasks'
});
See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.
In Javascript, when you execute a function, it's evaluated like:
expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does
That expression can be complex. So when you see undefined is not a function
it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.
And in this case, it was because you didn't put something where you thought you did.
You'll want to install the sshpass program. Then:
sshpass -p YOUR_PASSWORD sftp -oBatchMode=no -b YOUR_COMMAND_FILE_PATH USER@HOST
Obviously, it's better to setup public key authentication. Only use this if that's impossible to do, for whatever reason.
From C++ Primer:
The istringstream type reads a string, ostringstream writes a string, and stringstream reads and writes the string.
I come across some cases where it is both convenient and concise to use stringstream.
It is from one of the solutions for this leetcode problem. It demonstrates a very suitable case where the use of stringstream is efficient and concise.
Suppose a
and b
are complex numbers expressed in string format, we want to get the result of multiplication of a
and b
also in string format. The code is as follows:
string a = "1+2i", b = "1+3i";
istringstream sa(a), sb(b);
ostringstream out;
int ra, ia, rb, ib;
char buff;
// only read integer values to get the real and imaginary part of
// of the original complex number
sa >> ra >> buff >> ia >> buff;
sb >> rb >> buff >> ib >> buff;
out << ra*rb-ia*ib << '+' << ra*ib+ia*rb << 'i';
// final result in string format
string result = out.str()
It is also from a leetcode problem that requires you to simplify the given path string, one of the solutions using stringstream is the most elegant that I have seen:
string simplifyPath(string path) {
string res, tmp;
vector<string> stk;
stringstream ss(path);
while(getline(ss,tmp,'/')) {
if (tmp == "" or tmp == ".") continue;
if (tmp == ".." and !stk.empty()) stk.pop_back();
else if (tmp != "..") stk.push_back(tmp);
}
for(auto str : stk) res += "/"+str;
return res.empty() ? "/" : res;
}
Without the use of stringstream, it would be difficult to write such concise code.
If you are looking to avoid multiple code lines to save space, maybe this syntax could be useful:
java.util.ArrayList lisFieldNames = new ArrayList() {
{
add("value1");
add("value2");
}
};
Removing new lines, you can show it compressed as:

Well simple enough, I got it in a one liner (bash)
git branch | sed -n '/\* /s///p'
(credit: Limited Atonement)
And while I am there, the one liner to get the remote tracking branch (if any)
git rev-parse --symbolic-full-name --abbrev-ref @{u}
len(self.table)
checks for the length of the array, so you can use if-statements to find out if the length of the list is greater than 0 (not empty):
Python 2:
if len(self.table) > 0:
#Do code here
Python 3:
if(len(self.table) > 0):
#Do code here
It's also possible to use
if self.table:
#Execute if self.table is not empty
else:
#Execute if self.table is empty
to see if the list is not empty.
You could use Type.GetMember Method, then get the attribute info using reflection:
// display attribute of "currentPromotion"
var type = typeof(UserPromotion);
var memberInfo = type.GetMember(currentPromotion.ToString());
var attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
var description = ((DisplayAttribute)attributes[0]).Name;

Another approach is to make a custom layout class like the one below. This layout first draws its contents to an offscreen bitmap, masks the offscreen bitmap with a rounded rect and then draws the offscreen bitmap on the actual canvas.
I tried it and it seems to work (at least for my simple testcase). It will of course affect performance compared to a regular layout.
package com.example;
import android.content.Context;
import android.graphics.*;
import android.util.AttributeSet;
import android.util.DisplayMetrics;
import android.util.TypedValue;
import android.widget.FrameLayout;
public class RoundedCornerLayout extends FrameLayout {
private final static float CORNER_RADIUS = 40.0f;
private Bitmap maskBitmap;
private Paint paint, maskPaint;
private float cornerRadius;
public RoundedCornerLayout(Context context) {
super(context);
init(context, null, 0);
}
public RoundedCornerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
init(context, attrs, 0);
}
public RoundedCornerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init(context, attrs, defStyle);
}
private void init(Context context, AttributeSet attrs, int defStyle) {
DisplayMetrics metrics = context.getResources().getDisplayMetrics();
cornerRadius = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, CORNER_RADIUS, metrics);
paint = new Paint(Paint.ANTI_ALIAS_FLAG);
maskPaint = new Paint(Paint.ANTI_ALIAS_FLAG | Paint.FILTER_BITMAP_FLAG);
maskPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR));
setWillNotDraw(false);
}
@Override
public void draw(Canvas canvas) {
Bitmap offscreenBitmap = Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Bitmap.Config.ARGB_8888);
Canvas offscreenCanvas = new Canvas(offscreenBitmap);
super.draw(offscreenCanvas);
if (maskBitmap == null) {
maskBitmap = createMask(canvas.getWidth(), canvas.getHeight());
}
offscreenCanvas.drawBitmap(maskBitmap, 0f, 0f, maskPaint);
canvas.drawBitmap(offscreenBitmap, 0f, 0f, paint);
}
private Bitmap createMask(int width, int height) {
Bitmap mask = Bitmap.createBitmap(width, height, Bitmap.Config.ALPHA_8);
Canvas canvas = new Canvas(mask);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setColor(Color.WHITE);
canvas.drawRect(0, 0, width, height, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR));
canvas.drawRoundRect(new RectF(0, 0, width, height), cornerRadius, cornerRadius, paint);
return mask;
}
}
Use this like a normal layout:
<com.example.RoundedCornerLayout
android:layout_width="200dp"
android:layout_height="200dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/test"/>
<View
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#ff0000"
/>
</com.example.RoundedCornerLayout>
I usually just specify this in an .htaccess
file or the vhost.conf
on the domain I'm working on. Add this to one of these files:
php_admin_value error_log "/var/www/vhosts/example.com/error_log"
If you want to split by values in one of the columns, you can use lapply
. For instance, to split ChickWeight
into a separate dataset for each chick:
data(ChickWeight)
lapply(unique(ChickWeight$Chick), function(x) ChickWeight[ChickWeight$Chick == x,])
my datagridview is editonEnter mode . so it refresh only after i leave cell or after i revisit and exit cell twice.
to trigger this iimedately . i unfocus from datagridview . then refocus it.
this.SelectNextControl(dgv1,true,true,false,true);
Application.DoEvents(); //this does magic
dgv1.Focus();
I would like to humbly add that according to this SO source: https://stackoverflow.com/a/14671362/1743693, this kind of trouble is now partially solved simply by using the following jQuery instruction:
<script>
$.support.cors = true;
</script>
I tried it on IE10.0.9200, and it worked immediately (using jquery-1.9.0.js).
On chrome 28.0.1500.95 - this instruction doesn't work (this happens all over as david complains in the comments at the link above)
Running chrome with --allow-file-access-from-files did not work for me (as Maistora's claims above)
Simply do this
var key = "keyOne";
var obj = {};
obj[key] = someValue;
Javascript is base of jQuery.
jQuery is a wrapper of JavaScript, with much pre-written functionality and DOM traversing.
If you aren't using an auto-filter (i.e. you have manually hidden rows), you will need to use the AGGREGATE
function instead of SUBTOTAL
.
Although adequate answers have already been given, I'd like to propose a less verbose solution, that can be used without the helper methods available in an MVC controller class. Using a third party library called "RazorEngine" you can use .Net file IO to get the contents of the razor file and call
string html = Razor.Parse(razorViewContentString, modelObject);
Get the third party library here.
There's a WebKit-Sharp component on Mono's Subversion Server. I can't find any web-viewable documentation on it, and I'm not even sure if it's WinForms or GTK# (can't grab the source from here to check at the moment), but it's probably your best bet, either way.
I think this component is CLI wrapper around webkit for Ubuntu. So this wrapper most likely could be not working on win32
Try check another variant - project awesomium - wrapper around google project "Chromium" that use webkit. Also awesomium has features like to should interavtive web pages on 3D objects under WPF

tax = (EditText) findViewById( R.id.editTax );
total = (EditText) findViewById( R.id.editTotal );

total = (EditText) findViewById( R.id.editTotal );
String x = ("\nItem/Price: " + item.getText() + price.getText() + "\nTax/Total" + tax.getText() + total.getText());
Toast.makeText( this, x, Toast.LENGTH_SHORT ).show();
try {
this.WriteBusiness(bizname,storeno,rcpt,item,price,tax,total);
String vv = tax.getText().toString();
System.console().printf( "%s", vv );
//new XMLDivisionWriter(getString(R.string.SDDoc) + "/tax_div_business.xml");
} catch (ReflectiveOperationException e) {
e.printStackTrace();
}
}
There! The debate is settled!

You need some form of iteration here, as val
(except when called with a function) only works on the first element:
$("input[placeholder]").val($("input[placeholder]").attr("placeholder"));
should be:
$("input[placeholder]").each( function () {
$(this).val( $(this).attr("placeholder") );
});
or
$("input[placeholder]").val(function() {
return $(this).attr("placeholder");
});
if sum of column is 0 then display empty
select if(sum(column)>0,sum(column),'')

The usage of Base64 I'm going to describe here is somewhat a hack. So if you don't like hacks, please do not go on.
I went into trouble when I discovered that MySQL's utf8 does not support 4-byte unicode characters since it uses a 3-byte version of utf8. So what I did to support full 4-byte unicode over MySQL's utf8? Well, base64 encode strings when storing into the database and base64 decode when retrieving.
Since base64 encoding and decoding is very fast, the above worked perfectly.
You have the following points to take note of:
Base64 encoding uses 33% more storage
Strings stored in the database wont be human readable (You could sell that as a feature that database strings use a basic form of encryption).
You could use the above method for any storage engine that does not support unicode.
I use this solution:
in the manifest, inside your activity tag:
android:label="@string/empty_string"
and in strings.xml:
<string name="empty_string">""</string>
This way you keep ActionBar (or Toolbar) with the title, but when Activity if created the title is automatically empty.

You can do it for macOS, too. Ok, not through code, but with some simple steps:
Actually it is a general thing not specific to electron. You can change the icon of many macOS apps like this.
It's compiled to bytecode which can be used much, much, much faster.
The reason some files aren't compiled is that the main script, which you invoke with python main.py
is recompiled every time you run the script. All imported scripts will be compiled and stored on the disk.
Important addition by Ben Blank:
It's worth noting that while running a compiled script has a faster startup time (as it doesn't need to be compiled), it doesn't run any faster.
Setup:
My OS windows 8 64bit
Eclipse version Standard/SDK Kepler Service Release 2
My JDK is jdk-8u5-windows-i586
My JRE is jre-8u5-windows-i586
This how I overcome my error.
At the very first my Class.forName("sun.jdbc.odbc.JdbcOdbcDriver")
also didn't work.
Then I login to this website and downloaded the UCanAccess 2.0.8 zip (as Mr.Gord Thompson said) file and unzip it.
Then you will also able to find these *.jar files in that unzip folder:
ucanaccess-2.0.8.jar
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.0.4.jar
Then what I did was I copied all these 5 files and paste them in these 2 locations:
C:\Program Files (x86)\eclipse\lib
C:\Program Files (x86)\eclipse\lib\ext
(I did that funny thing becoz I was unable to import these libraries to my project)
Then I reopen the eclipse with my project.then I see all that *.jar files in my project's JRE System Library folder.
Finally my code works.
public static void main(String[] args)
{
try
{
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\Hasith\\Documents\\JavaDatabase1.mdb");
Statement stment = conn.createStatement();
String qry = "SELECT * FROM Table1";
ResultSet rs = stment.executeQuery(qry);
while(rs.next())
{
String id = rs.getString("ID") ;
String fname = rs.getString("Nama");
System.out.println(id + fname);
}
}
catch(Exception err)
{
System.out.println(err);
}
//System.out.println("Hasith Sithila");
}
Yes, you can use the *args
(splat) syntax:
function_that_needs_strings(*my_list)
where my_list
can be any iterable; Python will loop over the given object and use each element as a separate argument to the function.
See the call expression documentation.
There is a keyword-parameter equivalent as well, using two stars:
kwargs = {'foo': 'bar', 'spam': 'ham'}
f(**kwargs)
and there is equivalent syntax for specifying catch-all arguments in a function signature:
def func(*args, **kw):
# args now holds positional arguments, kw keyword arguments
Starting with SQL Server 2012, you can use FORMAT and DATEFROMPARTS to solve this problem. (If you want month names from other cultures, change: en-US
)
select FORMAT(DATEFROMPARTS(1900, @month_num, 1), 'MMMM', 'en-US')
If you want a three-letter month:
select FORMAT(DATEFROMPARTS(1900, @month_num, 1), 'MMM', 'en-US')
If you really want to, you can create a function for this:
CREATE FUNCTION fn_month_num_to_name
(
@month_num tinyint
)
RETURNS varchar(20)
AS
BEGIN
RETURN FORMAT(DATEFROMPARTS(1900, @month_num, 1), 'MMMM', 'en-US')
END
This worked for me and also worked with bootstrap tables
<style>
.table td, .table th {
font-size: 10px;
}
</style>
Use this code.
driver.FindElement(By.XPath(".//[@id='header']/div/div[3]/div/form/input[1]")).SendKeys("25025");
At least three ways:
var result = /[^/]*$/.exec("foo/bar/test.html")[0];
...which says "grab the series of characters not containing a slash" ([^/]*
) at the end of the string ($
). Then it grabs the matched characters from the returned match object by indexing into it ([0]
); in a match object, the first entry is the whole matched string. No need for capture groups.
lastIndexOf
and substring
:var str = "foo/bar/test.html";
var n = str.lastIndexOf('/');
var result = str.substring(n + 1);
lastIndexOf
does what it sounds like it does: It finds the index of the last occurrence of a character (well, string) in a string, returning -1 if not found. Nine times out of ten you probably want to check that return value (if (n !== -1)
), but in the above since we're adding 1 to it and calling substring, we'd end up doing str.substring(0)
which just returns the string.
Array#split
Sudhir and Tom Walters have this covered here and here, but just for completeness:
var parts = "foo/bar/test.html".split("/");
var result = parts[parts.length - 1]; // Or parts.pop();
split
splits up a string using the given delimiter, returning an array.
The lastIndexOf
/ substring
solution is probably the most efficient (although one always has to be careful saying anything about JavaScript and performance, since the engines vary so radically from each other), but unless you're doing this thousands of times in a loop, it doesn't matter and I'd strive for clarity of code.
A very simple and elegant solution to this is provided by W3C. Simply use the margin:0 auto declaration as follows:
.top_image img { margin:0 auto; }
More information and examples from W3C.
Both the answers provided above work fine.

I would try the following syntax - it works for me.
msiexec /x filename.msi /q
With version 1.7 of the official 10gen driver, this is the current (non-obsolete) API:
const string uri = "mongodb://localhost/mydb";
var client = new MongoClient(uri);
var db = client.GetServer().GetDatabase(new MongoUrl(uri).DatabaseName);
var collection = db.GetCollection("mycollection");
specifically I want to overload
Boolean.Parse
to allow an int argument.
Would an extension for int work?
public static bool ToBoolean(this int source){
// do it
// return it
}
Then you can call it like this:
int x = 1;
bool y = x.ToBoolean();
You have also a very good testing frameworks to create such a stub. One of my preferrable is Mockito There is also EasyMock and others... But Mockito is great you should read it - very elegant and powerfull package

JSONP is a great away to get around cross-domain scripting errors. You can consume a JSONP service purely with JS without having to implement a AJAX proxy on the server side.
You can use the b1t.co service to see how it works. This is a free JSONP service that alllows you to minify your URLs. Here is the url to use for the service:
http://b1t.co/Site/api/External/MakeUrlWithGet?callback=[resultsCallBack]&url=[escapedUrlToMinify]
For example the call, http://b1t.co/Site/api/External/MakeUrlWithGet?callback=whateverJavascriptName&url=google.com
would return
whateverJavascriptName({"success":true,"url":"http://google.com","shortUrl":"http://b1t.co/54"});
And thus when that get's loaded in your js as a src, it will automatically run whateverJavascriptName which you should implement as your callback function:
function minifyResultsCallBack(data)
{
document.getElementById("results").innerHTML = JSON.stringify(data);
}
To actually make the JSONP call, you can do it about several ways (including using jQuery) but here is a pure JS example:
function minify(urlToMinify)
{
url = escape(urlToMinify);
var s = document.createElement('script');
s.id = 'dynScript';
s.type='text/javascript';
s.src = "http://b1t.co/Site/api/External/MakeUrlWithGet?callback=resultsCallBack&url=" + url;
document.getElementsByTagName('head')[0].appendChild(s);
}
A step by step example and a jsonp web service to practice on is available at: this post
To see the local packages installed in your project including their versions and without their dependencies, run the below command from the project's root directory. In a React native app this would include the react-native package.
npm list --depth 0
Or if you installed them with yarn:
yarn list --depth=0
And to get just a specific package:
npm list react-native --depth 0
yarn list --pattern react-native --depth=0
Include JSoup in your apps build.gradle file :

You can use Padding
widget in between those two widget or wrap those widgets with Padding
widget.
Update
SizedBox widget can be use in between two widget to add space between two widget and it makes code more readable than padding widget.
Ex:
Column(
children: <Widget>[
Widget1(),
SizedBox(height: 10),
Widget2(),
],
),
I've assumed a named JSONArray is a JSONObject and accessed the data from the server to populate an Android GridView. For what it is worth my method is:
private String[] fillTable( JSONObject jsonObject ) {
String[] dummyData = new String[] {"1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7", };
if( jsonObject != null ) {
ArrayList<String> data = new ArrayList<String>();
try {
// jsonArray looks like { "everything" : [{}, {},] }
JSONArray jsonArray = jsonObject.getJSONArray( "everything" );
int number = jsonArray.length(); //How many rows have got from the database?
Log.i( Constants.INFORMATION, "Number of ows returned: " + Integer.toString( number ) );
// Array elements look like this
//{"success":1,"error":0,"name":"English One","owner":"Tutor","description":"Initial Alert","posted":"2013-08-09 15:35:40"}
for( int element = 0; element < number; element++ ) { //visit each element
JSONObject jsonObject_local = jsonArray.getJSONObject( element );
// Overkill on the error/success checking
Log.e("JSON SUCCESS", Integer.toString( jsonObject_local.getInt(Constants.KEY_SUCCESS) ) );
Log.e("JSON ERROR", Integer.toString( jsonObject_local.getInt(Constants.KEY_ERROR) ) );
if ( jsonObject_local.getInt( Constants.KEY_SUCCESS) == Constants.JSON_SUCCESS ) {

Update your jar name in classpath accordingly.
There is another option that does not introduce global gotchas when trying to initialize multiple variables to the same value. Whether or not it is preferable to the long way is a judgement call. It will likely be slower and may or may not be more readable. In your specific case, I think that the long way is probably more readable and maintainable as well as being faster.
The other way utilizes Destructuring assignment.

I had a similar problem. I didn't quite need an ordered set but more a list with a fast indexOf
/contains
. As I didn't find anything out there I implemented one myself. Here's the code, it implements both Set

, though not all bulk list operations are as fast as the ArrayList
versions.

I believe that the body height being returned is the visible height. If you need the total page height, you could wrap your div tags in a containing div and get the height of that.
I actually tried to implement connection pooling on the django end using:
https://github.com/gmcguire/django-db-pool
but I still received this error, despite lowering the number of connections available to below the standard development DB quota of 20 open connections.
There is an article here about how to move your postgresql database to the free/cheap tier of Amazon RDS. This would allow you to set max_connections
higher. This will also allow you to pool connections at the database level using PGBouncer.
https://www.lewagon.com/blog/how-to-migrate-heroku-postgres-database-to-amazon-rds
UPDATE:
Heroku responded to my open ticket and stated that my database was improperly load balanced in their network. They said that improvements to their system should prevent similar problems in the future. Nonetheless, support manually relocated my database and performance is noticeably improved.
You go into your router configuration and forward port 80 to the LAN IP of the computer running the web server.
Then anyone outside your network (but not you inside the network) can access your site using your WAN IP address (whatismyipcom).
You should put the input for the last name into the same div where you have the first name.
<div>
<label for="username">First Name</label>
<input id="user_first_name" name="user[first_name]" size="30" type="text" />
<input id="user_last_name" name="user[last_name]" size="30" type="text" />
</div>
Then, in your CSS give your #user_first_name and #user_last_name height and float them both to the left. For example:
#user_first_name{
max-width:100px; /*max-width for responsiveness*/
float:left;
}
#user_lastname_name{
max-width:100px;
float:left;
}
Similar to other answers, I wanted to ensure my ASP.NET Core 2.1 environment setting persisted across deployments, but also only applied to the specific site.
According to Microsoft's documentation, it is possible to set the environment variable on the app pool using the following PowerShell command in IIS 10:
$appPoolName = "AppPool"
$envName = "Development"
cd "$env:SystemRoot\system32\inetsrv"
.\appcmd.exe set config -section:system.applicationHost/applicationPools /+"[name='$appPoolName'].environmentVariables.[name='ASPNETCORE_ENVIRONMENT',value='$envName']" /commit:apphost
I unfortunately still have to use IIS 8.5 and thought I was out of luck. However, it is still possible to run a simple PowerShell script to set a site-specific environment variable value for ASPNETCORE_ENVIRONMENT:
Import-Module -Name WebAdministration
$siteName = "Site"
$envName = "Development"
Set-WebConfigurationProperty -PSPath IIS:\ -Location $siteName -Filter /system.webServer/aspNetCore/environmentVariables -Name . -Value @{ Name = 'ASPNETCORE_ENVIRONMENT'; Value = $envName }
You don't need any date-specific functions for this, it's just string manipulation:
var parts = fecha2.value.split('-');
var newdate = parts[1]+'-'+parts[2]+'-'+(parseInt(parts[0], 10)%100);
For Ubuntu:
Happened with me when I updated docker.
You need to unmask the service and socket and then restart the service.
Following worked for me:
systemctl unmask docker.service
systemctl unmask docker.socket
systemctl start docker.service
What happend behind the scenes
systemd also has the ability to mark a unit as completely unstartable, automatically or manually, by linking it to /dev/null. This is called masking the unit, and is possible with the mask command.
sudo systemctl mask docker.service
You can check the list of masked services using:
sudo systemctl list-unit-files
To enable auto/manual start of service you need to unmask it using:
sudo sytemctl unmask docker.service
That depends on what you want to do, but as you said, getting an entity reference using find()
and then just updating that entity is the easiest way to do that.
I'd not bother about performance differences of the various methods unless you have strong indications that this really matters.
PowerShell has really wacky return semantics - at least when viewed from a more traditional programming perspective. There are two main ideas to wrap your head around:
Thus, the following two script blocks will do effectively the exact same thing:
$a = "Hello, World"
return $a
$a = "Hello, World"
$a
return
The $a variable in the second example is left as output on the pipeline and, as mentioned, all output is returned. In fact, in the second example you could omit the return entirely and you would get the same behavior (the return would be implied as the function naturally completes and exits).
Without more of your function definition I can't say why you are getting a PSMethod object. My guess is that you probably have something a few lines up that is not being captured and is being placed on the output pipeline.
It is also worth noting that you probably don't need those semicolons - unless you are nesting multiple expressions on a single line.
You can read more about the return semantics on the about_Return page on TechNet, or by invoking the help return
command from PowerShell itself.
Recent bash
versions allow fall-through by using ;&
in stead of ;;
:
they also allow resuming the case checks by using ;;&
there.

case "$n" in
3? )
echo -n thirty-
;;& #resume (to find ?4 later )
"24" )
echo -n twenty-
;& #fallthru
"4" | [13]4)
echo -n four
;;& # resume ( to find teen where needed )
"14" )
echo -n teen
esac
echo
done
sample output
4 = four
14 = fourteen
24 = twenty-four
34 = thirty-four
What helped me on Windows 10 was just ticking off "Read Only" of project node_modules

I found that this is simple and works great.

Maybe these steps are not quite correct, but I do like this:
stop docker compose: $ docker-compose down
remove the container: $ docker system prune -a
start docker compose: $ docker-compose up -d
Here's some functional code (Java 8) which returns the x position of the right most edge of the right most screen. If no screens are found, then it returns 0.
GraphicsDevice devices[];
devices = GraphicsEnvironment.
getLocalGraphicsEnvironment().
getScreenDevices();
return Stream.
of(devices).
map(GraphicsDevice::getDefaultConfiguration).
map(GraphicsConfiguration::getBounds).
mapToInt(bounds -> bounds.x + bounds.width).
max().
orElse(0);
Here are links to the JavaDoc.
GraphicsEnvironment.getLocalGraphicsEnvironment()
GraphicsEnvironment.getScreenDevices()

GraphicsConfiguration.getBounds()

React-Redux connect
is used to update store for every actions.
import { connect } from 'react-redux';
const AppContainer = connect(
mapStateToProps,
mapDispatchToProps

export default AppContainer;
It's very simply and clearly explained in this blog.
You can clone github project or copy paste the code from that blog to understand the Redux connect.
You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do
for (var i = myArray.length - 1; i >= 0; i--) { console.log(eval(myArray[i])); };
More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.
var result = {}; for (var i = myArray.length - 1; i >= 0; i--) { result[myArray[i]] = eval(myArray[i]); };
I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via
window['myVarName'] = 'namingCollisionsAreFun';

Here is an example of how to use strtok borrowed from MSDN.
And the relevant bits, you need to call it multiple times. The token
char* is the part you would stuff into an array (you can figure that part out).
char string[] = "A string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;
int main( void )
{
printf( "Tokens:\n" );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s\n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}
