Why don't you just save/serve the CSS file as UTF-8?
nav a:hover:after {
content: "?";
}
If that's not good enough, and you want to keep it all-ASCII:
nav a:hover:after {
content: "\2193";
}
The general format for a Unicode character inside a string is \000000
to \FFFFFF
– a backslash followed by six hexadecimal digits. You can leave out leading 0
digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.
Relevant part of the CSS2 spec:
Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:
- with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
- by providing exactly 6 hexadecimal digits: "\000026B" ("&B")
In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.
If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).
- Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
The identifier "te\st" is exactly the same identifier as "test".
Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).
Using SourceTree I was able to do this all from the UI
FILE.ext
to whatever.ext
whatever.ext
to file.ext
It's a bit tedious, but if you only need to do it to a few files it's pretty quick
The behavior of host objects <object>
is due to ECMA262 implementation dependent and set attribute by setAttribute()
method may fail.
I see two solutions:
soft: element.data = "http://www.google.com";
hard: remove object from DOM tree and create new one with changed data attribute.
For some reason it didn't work for me. So I had to use something else.
select "option_name_here", :from => "organizationSelect"
worked for me.
You can use the codecs module, like this:
import codecs
BLOCKSIZE = 1048576 # or some other, desired size in bytes
with codecs.open(sourceFileName, "r", "your-source-encoding") as sourceFile:
with codecs.open(targetFileName, "w", "utf-8") as targetFile:
while True:
contents = sourceFile.read(BLOCKSIZE)
if not contents:
break
targetFile.write(contents)
EDIT: added BLOCKSIZE
parameter to control file chunk size.

This is not an answer, really and I would have entered it as a comment had the question not been locked. This answers the question:
Why would you want it?
Assume you have a table with the sequence as the primary key and the sequence is generated by an insert trigger. If you wanted to have the sequence available for subsequent updates to the record, you need to have a way to extract that value.
In order to make sure you get the right one, you might want to wrap the INSERT and RonK's query in a transaction.
RonK's Query:
select MY_SEQ_NAME.currval from DUAL;
In the above scenario, RonK's caveat does not apply since the insert and update would happen in the same session.
According https://apiblueprint.org/documentation/examples/13-named-endpoints.html is a resource a "general" place of storage of the given entity - e.g. /customers/30654/orders, whereas an endpoint is the concrete action (HTTP Method) over the given resource. So one resource can have multiple endpoints.
You don't make it clear whether you're trying to modify the Querystring in place in the Request object. Since that property is read-only, I guess we'll assume you just want to mess with the string.
... In which case, it's borderline trivial.
You found the shorthand to set privileges for all existing tables in the given schema. The manual clarifies:
(but note that
ALL TABLES
is considered to include views and foreign tables).
Bold emphasis mine. serial
columns are implemented with nextval()
on a sequence as column default and, quoting the manual:
For sequences, this privilege allows the use of the
currval
andnextval
functions.
So if there are serial
columns, you'll also want to grant USAGE
(or ALL PRIVILEGES
) on sequences
GRANT USAGE ON ALL SEQUENCES IN SCHEMA foo TO mygrp;
Note: identity columns in Postgres 10 or later use implicit sequences that don't require additional privileges. (Consider upgrading serial
columns.)
You'll also be interested in DEFAULT PRIVILEGES
for users or schemas:
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT ALL PRIVILEGES ON TABLES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT USAGE ON SEQUENCES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo REVOKE ...;
This sets privileges for objects created in the future automatically - but not for pre-existing objects.
Default privileges are only applied to objects created by the targeted user (FOR ROLE my_creating_role
). If that clause is omitted, it defaults to the current user executing ALTER DEFAULT PRIVILEGES
. To be explicit:
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo GRANT ...;
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo REVOKE ...;
Note also that all versions of pgAdmin III have a subtle bug and display default privileges in the SQL pane, even if they do not apply to the current role. Be sure to adjust the FOR ROLE
clause manually when copying the SQL script.
var $div = $('#desiredDiv');
$div.contents().remove();
$div.html('<p>This is new HTML.</p>');
That should work just fine.
For some reason, the lib is present while compiling, but missing while running.
My situation is, two versions of one lib conflict.
For example, A depends on B and C, while B depends on D:1.0, C depends on D:1.1, maven may just import D:1.0. If A uses one class which is in D:1.1 but not in D:1.0, a NoClassDefFoundError will be throwed.
If you are in this situation too, you need to resolve the dependency conflict.
TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm
service.
The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.
To restart the service:
Note: prepend sudo if not root
Using SysV Init scripts directly:
/etc/init.d/php-fpm restart # typical
/etc/init.d/php5-fpm restart # debian-style
/etc/init.d/php7.0-fpm restart # debian-style PHP 7
Using service wrapper script
service php-fpm restart # typical
service php5-fpm restart # debian-style
service php7.0-fpm restart. # debian-style PHP 7
Using Upstart (e.g. ubuntu):
restart php7.0-fpm # typical (ubuntu is debian-based) PHP 7
restart php5-fpm # typical (ubuntu is debian-based)
restart php-fpm # uncommon
Using systemd (newer servers):
systemctl restart php-fpm.service # typical
systemctl restart php5-fpm.service # uncommon
systemctl restart php7.0-fpm.service # uncommon PHP 7
Or whatever the equivalent is on your system.
The above commands taken directly from this server fault answer
Other solutions may work. This is the 10 pound gorilla approach that has the advantage of being broadly applicable in this and similar cases:
Styles.xml:
<style name="AppTheme.FloatingAccentButtonOverlay" >
<item name="colorAccent">@color/colorFloatingActionBarAccent</item>
</style>
your layout xml:
<android.support.design.widget.FloatingActionButton
android:theme="AppTheme.FloatingAccentButtonOverlay"
...
</android.support.design.widget.FloatingActionButton>
Use a pattern along these lines:
function getValue(file) {
return lookupValue(file);
}
getValue('myFile.txt').then(function(res) {
// do whatever with res here
});
(although this is a bit redundant, I'm sure your actual code is more complicated)
QuerySelectorAll will get all the matching elements with defined selector. Here on the example I've used element's name(li
tag) to get all of the li
present inside the div with navbar
element.
let navbar = document_x000D_
.getElementById("navbar")_x000D_
.querySelectorAll('li');_x000D_
_x000D_
navbar.forEach((item, index) => {_x000D_
console.log({ index, item })_x000D_
});
_x000D_
_x000D_
<div id="navbar">_x000D_
<ul>_x000D_
<li id="navbar-One">One</li>_x000D_
<li id="navbar-Two">Two</li>_x000D_
<li id="navbar-Three">Three</li>_x000D_
<li id="navbar-Four">Four</li>_x000D_
<li id="navbar-Five">Five</li>_x000D_
</ul>_x000D_
</div>

There is an option in vb.net that lets you do all this.
The user wont be able to re-size the form or move it around, although there are other ways, this I think is the best.

Basically, all Maven is telling you is that certain dependencies in your project are not available in the central maven repository. The default is to look in your local .m2 folder (local repository), and then any configured repositories in your POM, and then the central maven repository. Look at the repositories section of the Maven reference.
The problem is that the project that was checked in didn't configure the POM in such a way that all the dependencies could be found and the project could be built from scratch.

On Android 4.4.4, it seems the only way I could stop an alpha fading animation on a View was calling View.animate().cancel()
(i.e., calling .cancel()
on the View's ViewPropertyAnimator
).
Here's the code I'm using for compatibility before and after ICS:
public void stopAnimation(View v) {
v.clearAnimation();
if (canCancelAnimation()) {
v.animate().cancel();
}
}
... with the method:
/**
* Returns true if the API level supports canceling existing animations via the
* ViewPropertyAnimator, and false if it does not
* @return true if the API level supports canceling existing animations via the
* ViewPropertyAnimator, and false if it does not
*/
public static boolean canCancelAnimation() {
return Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH;
}
Here's the animation that I'm stopping:
v.setAlpha(0f);
v.setVisibility(View.VISIBLE);
// Animate the content view to 100% opacity, and clear any animation listener set on the view.
v.animate()
.alpha(1f)
.setDuration(animationDuration)
.setListener(null);

Yes, should try reinstall mysql, but use the --reinstall
flag to force a package reconfiguration. So the operating system service configuration is not skipped:
sudo apt --reinstall install mysql-server
Well, I figured out the problem.
Basically Go starting path for import is $HOME/go/src
So I just needed to add myapp
in front of the package names, that is, the import should be:
import (
"log"
"net/http"
"myapp/common"
"myapp/routers"
)
you could also do it this way, in my case i use it before and after an h1 (brute force it ehehehe)
.titleImage::before {
content: "--------";
letter-spacing: -3px;
}
.titreImage::after {
content: "--------";
letter-spacing: -3px;
}
If the letter spacing makes it so the line get in the text just use a margin to push it away!

I got the solution for the Android Studio installation after trying everything that I could find on the Internet. If you're using Android Studio and getting this error:
Find [Path_to_Android_SDK]\sdk\tools\android.bat
.
In my case, it was in C:\Users\Nathan\AppData\Local\Android\android-studio\sdk\tools\android.bat
.
Right-click it, hit Edit
, and scroll all the way down to the bottom.
Find where it says: call %java_exe% %REMOTE_DEBUG% ...
Replace that with call %java_exe% -Djava.net.preferIPv4Stack=true %REMOTE_DEBUG% ...
Restart Android Studio/SDK and everything works. This fixed many issues for me, including being unable to fetch XML files or create new projects.

If you're looking for something lightweight, I'd append a parameter to your action.
[HttpPost]
public ActionResult ShowAllMobileDetails(MobileViewModel MV, string ddlVendor)
{
string strDDLValue = ddlVendor; // Of course, this becomes silly.
return View(MV);
}
What's happening in your code now, is you're passing the first string argument of "ddlVendor" to Html.DropDownList
, and that's telling the MVC framework to create a <select>
element with a name
of "ddlVendor." When the user submits the form client-side, then, it will contain a value to that key.
When MVC tries to parse that request into MV
, it's going to look for MobileList
and Vendor
and not find either, so it's not going to be populated. By adding this parameter, or using FormCollection
as another answer has suggested, you're asking MVC to specifically look for a form element with that name, so it should then populate the parameter value with the posted value.

With C++11 for measuring the execution time of a piece of code, we can use the now() function:
auto start = chrono::steady_clock::now();
// Insert the code that will be timed
auto end = chrono::steady_clock::now();
// Store the time difference between start and end
auto diff = end - start;
If you want to print the time difference between start and end in the above code, you could use:
cout << chrono::duration <double, milli> (diff).count() << " ms" << endl;
If you prefer to use nanoseconds, you will use:
cout << chrono::duration <double, nano> (diff).count() << " ns" << endl;
The value of the diff variable can be also truncated to an integer value, for example, if you want the result expressed as:
diff_sec = chrono::duration_cast<chrono::nanoseconds>(diff);
cout << diff_sec.count() << endl;

KeyPress is a higher level of abstraction than KeyDown (and KeyUp). KeyDown and KeyUp are hardware related: the actual action of a key on the keyboard. KeyPress is more "I received a character from the keyboard".

Then:
System.out.println(element.getValue()); // Result: Your message

lines = open(file_name, 'r').readlines()
lines[line_num] = text
out = open(file_name, 'w')
out.writelines(lines)
out.close()
And then:
replace_line('stats.txt', 0, 'Mage')
@rob-juurlink I improved a bit on your solution:
instead of each route needing an active tab; and needing to set the active tab in each controller I do this:
var App = angular.module('App',[]);
App.config(['$routeProvider', function($routeProvider){
$routeProvider.
when('/dashboard', {
templateUrl: 'partials/dashboard.html',
controller: Ctrl1
}).
when('/lab', {
templateUrl: 'partials/lab.html',
controller: Ctrl2
});
}]).run(['$rootScope', '$location', function($rootScope, $location){
var path = function() { return $location.path();};
$rootScope.$watch(path, function(newVal, oldVal){
$rootScope.activetab = newVal;
});
}]);
And the HTML looks like this. The activetab is just the url that relates to that route. This just removes the need to add code in each controller (dragging in dependencies like $route and $rootScope if this is the only reason they're used)
<ul>
<li ng-class="{active: activetab=='/dashboard'}">
<a href="#/dashboard">dashboard</a>
</li>
<li ng-class="{active: activetab=='/lab'}">
<a href="#/lab">lab</a>
</li>
</ul>
Map:
Map transformation.
The map works on a single Row at a time.
Map returns after each input Row.
The map doesn’t hold the output result in Memory.
Map no way to figure out then to end the service.
// map example
val dfList = (1 to 100) toList
val df = dfList.toDF()
val dfInt = df.map(x => x.getInt(0)+2)
display(dfInt)
MapPartition:
MapPartition transformation.
MapPartition works on a partition at a time.
MapPartition returns after processing all the rows in the partition.
MapPartition output is retained in memory, as it can return after processing all the rows in a particular partition.
MapPartition service can be shut down before returning.
// MapPartition example
Val dfList = (1 to 100) toList
Val df = dfList.toDF()
Val df1 = df.repartition(4).rdd.mapPartition((int) => Iterator(itr.length))
Df1.collec()
//display(df1.collect())
For more details, please refer to the Spark map vs mapPartitions transformation article.
Hope this is helpful!

git pull

git pull

only differ in that the latter will only "update" origin/branch and not all origin/* as git pull
does.
git pull origin/branch
will just not work because it's trying to do a git fetch origin/branch

If you are looking for row count of all tables in all databases (which was what I was looking for) then I found this combination of this and this to work. No idea whether it is optimal or not:
SET NOCOUNT ON
DECLARE @AllTables table (DbName sysname,SchemaName sysname, TableName sysname, RowsCount int )
DECLARE
@SQL nvarchar(4000)
SET @SQL='SELECT ''?'' AS DbName, s.name AS SchemaName, t.name AS TableName, p.rows AS RowsCount FROM [?].sys.tables t INNER JOIN sys.schemas s ON t.schema_id=s.schema_id INNER JOIN [?].sys.partitions p ON p.OBJECT_ID = t.OBJECT_ID'
INSERT INTO @AllTables (DbName, SchemaName, TableName, RowsCount)
EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT DbName, SchemaName, TableName, SUM(RowsCount), MIN(RowsCount), SUM(1)
FROM @AllTables
WHERE RowsCount > 0
GROUP BY DbName, SchemaName, TableName
ORDER BY DbName, SchemaName, TableName
You basically have two options.
If you use the same user on both machines you need to copy the .pub key to your PC, so GitHub knows that you are the same user.
If you have created a new .pub file for your PC and want to treat the machines as different users, you need to register the new .pub file on the GitHub website.
If this still doesn't work it might be because ssh is not configured correctly and that ssh fail to find the location of your keys. Try
ssh -vv [email protected]

Structure packing suppresses structure padding, padding used when alignment matters most, packing used when space matters most.
Some compilers provide #pragma
to suppress padding or to make it packed to n number of bytes. Some provide keywords to do this. Generally pragma which is used for modifying structure padding will be in the below format (depends on compiler):
#pragma pack(n)
For example ARM provides the __packed
keyword to suppress structure padding. Go through your compiler manual to learn more about this.
So a packed structure is a structure without padding.
Generally packed structures will be used
to save space
to format a data structure to transmit over network using some
protocol (this is not a good practice of course because you need to
deal with endianness)

Rails 5 migration changes
eg:
rails g model Student student_name:string age:integer
if you want to change student_name column as name
Note:- if you not run rails db:migrate
You can do following steps
rails d model Student student_name:string age:integer
This will remove generated migration file, Now you can correct your column name
rails g model Student name:string age:integer
If you migrated(rails db:migrate), following options to change column name
rails g migration RemoveStudentNameFromStudent student_name:string
rails g migration AddNameToStudent name:string
From the MDN docs on Function.prototype.bind()
:
The bind() method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.
So, what does that mean?!
Well, let's take a function that looks like this :
var logProp = function(prop) {
console.log(this[prop]);
};
Now, let's take an object that looks like this :
var Obj = {
x : 5,
y : 10
};
We can bind our function to our object like this :
Obj.log = logProp.bind(Obj);
Now, we can run Obj.log
anywhere in our code :
Obj.log('x'); // Output : 5
Obj.log('y'); // Output : 10
This works, because we bound the value of this
to our object Obj
.
Where it really gets interesting, is when you not only bind a value for this
, but also for its argument prop
:
Obj.logX = logProp.bind(Obj, 'x');
Obj.logY = logProp.bind(Obj, 'y');
We can now do this :
Obj.logX(); // Output : 5
Obj.logY(); // Output : 10
Unlike with Obj.log
, we do not have to pass x
or y
, because we passed those values when we did our binding.

TemperatureData.objects.filter(id=1).update(value=F('value') + 1)
Try this:

Your @POST
method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:
@XmlRootElement
public class MyJaxBean {
@XmlElement public String param1;
@XmlElement public String param2;
}
Then your @POST
method would look like the following:
@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
System.out.println("param1 = " + input.param1);
System.out.println("param2 = " + input.param2);
}
This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input
in this case. The actual message would look something like:
POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com
{"param1":"hello","param2":"world"}
Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.
HTML <FORM>
The parameters would be annotated using @FormParam:
@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
@FormParam("param2") String param2) {
...
}
The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:
POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25
param1=hello¶m2=world
The content is URL encoded in this case.
If you do not know the names of the FormParam's you can do the following:
@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
...
}
HTTP Headers
You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:
@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
@HeaderParam("param2") String param2) {
...
}
Here's what the HTTP message would look like. Note that this POST does not have a body.
POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world
I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.
HTTP Query Parameters
This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.
@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
@QueryParam("param2") String param2) {
...
}
Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:
POST /create?param1=hello¶m2=world HTTP/1.1
Content-Length: 0
Host: www.example.com
You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.
HTTP Path Parameters
Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:
@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
@PathParam("param2") String param2) {
...
}
The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.
POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com
This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.
As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM
-based HTML pages, then use @FormParam
. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer
implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM
encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.
Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.
Ok, for this first of all you need to use Device Policy Manager, and need to make your device Admin device. After that you have to create one BroadCast receiver and one service. I am posting code here and its working fine.
MainActivity:
public class MainActivity extends Activity {
private static final int REQUEST_CODE = 0;

The only thing that a computer can store is bytes.
To store anything in a computer, you must first encode it, i.e. convert it to bytes. For example:
MP3
, WAV
, etc.PNG
, JPEG
, etc. ASCII
, UTF-8
, etc.MP3
, WAV
, PNG
, JPEG
, ASCII
and UTF-8
are examples of encodings. An encoding is a format to represent audio, images, text, etc in bytes.
In Python, a byte string is just that: a sequence of bytes. It isn't human-readable. Under the hood, everything must be converted to a byte string before it can be stored in a computer.
On the other hand, a character string, often just called a "string", is a sequence of characters. It is human-readable. A character string can't be directly stored in a computer, it has to be encoded first (converted into a byte string). There are multiple encodings through which a character string can be converted into a byte string, such as ASCII
and UTF-8
.
'I am a string'.encode('ASCII')
The above Python code will encode the string 'I am a string'
using the encoding ASCII
. The result of the above code will be a byte string. If you print it, Python will represent it as b'I am a string'
. Remember, however, that byte strings aren't human-readable, it's just that Python decodes them from ASCII
when you print them. In Python, a byte string is represented by a b
, followed by the byte string's ASCII
representation.
A byte string can be decoded back into a character string, if you know the encoding that was used to encode it.
b'I am a string'.decode('ASCII')
The above code will return the original string 'I am a string'
.
Encoding and decoding are inverse operations. Everything must be encoded before it can be written to disk, and it must be decoded before it can be read by a human.
As others have said, Dir::foreach
is a good option here. However, note that Dir::foreach
and Dir::entries
will always include .
and ..
(the current and parent directories). You will generally not want to work on them, so you can use Dir::each_child
or Dir::children
(as suggested by ma11hew28) or do something like this:
Dir.foreach('/path/to/dir') do |filename|
next if filename == '.' or filename == '..'
# Do work on the remaining files & directories
end
Dir::foreach
and Dir::entries
(as well as Dir::each_child
and Dir::children
) also include hidden files & directories. Often this is what you want, but if it isn't, you need to do something to skip over them.
Alternatively, you might want to look into Dir::glob
which provides simple wildcard matching:
Dir.glob('/path/to/dir/*.rb') do |rb_filename|
# Do work on files & directories ending in .rb
end
Okay turned out that I made a really silly mistake. The device I am using for testing is running Android 4.0.4, API level 15.

This is a sledgehammer approach to replacing raw UNICODE with HTML. I haven't seen any other place to put this solution, but I assume others have had this problem.
Apply this str_replace function to the RAW JSON, before doing anything else.
function unicode2html($str){
$i=65535;
while($i>0){
$hex=dechex($i);
$str=str_replace("\u$hex","&#$i;",$str);
$i--;
}
return $str;
}
This won't take as long as you think, and this will replace ANY unicode with HTML.
Of course this can be reduced if you know the unicode types that are being returned in the JSON.
For example my code was getting lots of arrows and dingbat unicode. These are between 8448 an 11263. So my production code looks like:
$i=11263;
while($i>08448){
...etc...
You can look up the blocks of Unicode by type here: http://unicode-table.com/en/ If you know you're translating Arabic or Telegu or whatever, you can just replace those codes, not all 65,000.
You could apply this same sledgehammer to simple encoding:
$str=str_replace("\u$hex",chr($i),$str);
Simply pass latitude, longitude and your Google API Key to the following query string, you will get a json array, fetch your city from there.
https://maps.googleapis.com/maps/api/geocode/json?latlng=44.4647452,7.3553838&key=YOUR_API_KEY
Note: Ensure that no space exists between the latitude and longitude values when passed in the latlng parameter.
In C#, they are interchangeable (although method is the proper term) because you cannot write a method without incorporating it into a class. If it were independent of a class, then it would be a function. Methods are functions that operate through a designated class.
Try this I think this is better.
var images = [];
function preload() {
for (var i = 0; i < arguments.length; i++) {
images[i] = new Image();
images[i].src = preload.arguments[i];
}
}
//-- usage --//
preload(
"http://domain.tld/gallery/image-001.jpg",
"http://domain.tld/gallery/image-002.jpg",
"http://domain.tld/gallery/image-003.jpg"
)

That's not JSON at all, it's just Javascript objects. JSON is a text representation of data, that uses a subset of the Javascript syntax.
The reason that you can't find any information about manipulating JSON using jQuery is because jQuery has nothing that can do that, and it's generally not done at all. You manipulate the data in the form of Javascript objects, and then turn it into a JSON string if that is what you need. (jQuery does have methods for the conversion, though.)
What you have is simply an object that contains an array, so you can use all the knowledge that you already have. Just use data.items
to access the array.
For example, to add another item to the array using dynamic values:
// The values to put in the item
var id = 7;
var name = "The usual suspects";
var type = "crime";
// Create the item using the values
var item = { id: id, name: name, type: type };
// Add the item to the array
data.items.push(item);
Even more, you can inherit generics :)

It is really easy to do a bulk insert in Laravel with or without the query builder. You can use the following official approach.
Entity::upsert([
['name' => 'Pierre Yem Mback', 'city' => 'Eseka', 'salary' => 10000000],
['name' => 'Dial rock 360', 'city' => 'Yaounde', 'salary' => 20000000],
['name' => 'Ndibou La Menace', 'city' => 'Dakar', 'salary' => 40000000]
], ['name', 'city'], ['salary']);

Supports globbing, too:
% git log --all -- '**/my_file.png'
The single quotes are necessary (at least if using the Bash shell) so the shell passes the glob pattern to git unchanged, instead of expanding it (just like with Unix find
).
The internal set of single quotes in your code is killing the string. Whenever you hit a single quote it ends the string and continues processing. You'll want something like:
$thisstring = 'this string is long \' in needs escaped single quotes or nothing will run';
The reason #2 fails is because sys.modules['module']
does not exist (the import routine has its own scope, and cannot see the module
local name), and there's no module
module or package on-disk. Note that you can separate multiple imported names by commas.
from package.subpackage.module import attribute1, attribute2, attribute3
Also:
from package.subpackage import module

Any number of files in a directory are a single package; symbols declared in one file are available to the others without any import
s or qualifiers. All of the files do need the same package foo
declaration at the top (or you'll get an error from go build
).
You do need GOPATH
set to the directory where your pkg
, src
, and bin
directories reside. This is just a matter of preference, but it's common to have a single workspace for all your apps (sometimes $HOME
), not one per app.
Normally a Github path would be github.com/username/reponame
(not just github.com/xxxx
). So if you want to have main
and another package, you may end up doing something under workspace/src
like
github.com/
username/
reponame/
main.go // package main, importing "github.com/username/reponame/b"
b/
b.go // package b
Note you always import with the full github.com/...
path: relative imports aren't allowed in a workspace. If you get tired of typing paths, use goimports
. If you were getting by with go run
, it's time to switch to go build
: run
deals poorly with multiple-file main
s and I didn't bother to test but heard (from Dave Cheney here) go run
doesn't rebuild dirty dependencies.
Sounds like you've at least tried to set GOPATH to the right thing, so if you're still stuck, maybe include exactly how you set the environment variable (the command, etc.) and what command you ran and what error happened. Here are instructions on how to set it (and make the setting persistent) under Linux/UNIX and here is the Go team's advice on workspace setup. Maybe neither helps, but take a look and at least point to which part confuses you if you're confused.
These are the primitive types in Java:
All the other types are reference types: they reference objects.
This is the first part of the Java tutorial about the basics of the language.
As can be seen from previous posts, one can argue that if class functionality needs to be circumvented then something is wrong in the class architecture. That might be true, but one cannot always restructure or refactor the class structure on a large mature project. The various levels of change management might be one problem, but to keep existing functionality operating the same after refactoring is not always a trivial task, especially if time constraints apply. On a mature project it can be quite an undertaking to keep various regression tests from passing after a code restructure; there are often obscure "oddities" that show up. We had a similar problem in some cases inherited functionality should not execute (or should perform something else). The approach we followed below, was to put the base code that need to be excluded in a separate virtual function. This function can then be overridden in the derived class and the functionality excluded or altered. In this example "Text 2" can be prevented from output in the derived class.
public class Base
{
public virtual void Foo()
{
Console.WriteLine("Hello from Base");
}
}
public class Derived : Base
{
public override void Foo()
{
base.Foo();
Console.WriteLine("Text 1");
WriteText2Func();
Console.WriteLine("Text 3");
}
protected virtual void WriteText2Func()
{
Console.WriteLine("Text 2");
}
}
public class Special : Derived
{
public override void WriteText2Func()
{
//WriteText2Func will write nothing when
//method Foo is called from class Special.
//Also it can be modified to do something else.
}
}
This will log the id of the element that's been clicked: addFields.
<button id="addFields" onclick="addFields()">+</button>
<script>
function addFields(){
console.log(event.toElement.id)
}
</script>
The function that it returns has a call signature, but you told Typescript to completely ignore that by adding : any
in its signature.
In Android Studio 3:
or use Android Debug Database
For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);
If you want it to download and install from your own server then use the following code
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
startActivity(intent);
Just use the modulus
loop through the list and run the following on each item
if(num % 2 == 0)
{
//is even
}
else
{
//is odd
}
Alternatively if you want to know if all are even you can do something like this:
bool allAreEven = lst.All(x => x % 2 == 0);
public ActionResult CreatePerson (string id)
window.location.href = '@Url.Action("CreatePerson", "Person" , new {id = "ID"})'.replace("ID",id);
public ActionResult CreatePerson (int id)
window.location.href = '@Url.Action("CreatePerson", "Person" , new {id = "ID"})'.replace("ID", parseInt(id));
It's not sure what you mean with 'the program', but if you want to limit your application to one instance then you can use a Mutex to make sure that your application isn't already running.
[STAThread]
static void Main()
{
Mutex mutex = new System.Threading.Mutex(false, "MyUniqueMutexName");
try
{
if (mutex.WaitOne(0, false))
{
// Run the application
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm());
}
else
{
MessageBox.Show("An instance of the application is already running.");
}
}
finally
{
if (mutex != null)
{
mutex.Close();
mutex = null;
}
}
}
The correct answer is, that, because the '%'
-sign is part of your search expression, it should be part of your VALUE, so whereever you SET @LastName
(be it from a programming language or from TSQL) you should set it to '%' + [userinput] + '%'
or, in your example:
DECLARE @LastName varchar(max)
SET @LastName = 'ning'
SELECT Employee WHERE LastName LIKE '%' + @LastName + '%'
What you can utilize is some sort of templating engine like pug (formerly jade). To enable it you should do the following:
npm install --save pug
- to add it to the project and package.json fileapp.set('view engine', 'pug');
- register it as a view engine in express./views
folder and add a simple .pug
file like so:html
head
title= title
body
h1= message
note that the spacing is very important!
app.get('/', function (req, res) {
res.render('index', { title: 'Hey', message: 'Hello there!'});
});
This will render an index.html page with the variables passed in node.js changed to the values you have provided. This has been taken directly from the expressjs templating engine page: http://expressjs.com/en/guide/using-template-engines.html
For more info on pug you can also check: https://github.com/pugjs/pug
The outcome can be summarized as
LinqToSql for small sites, and prototypes. It really saves time for Prototyping.
Sps : Universal. I can fine tune my queries and always check ActualExecutionPlan / EstimatedExecutionPlan.
What you have should work but can be reduced to:

Can you provide an example name and search term where this doesn't work?
If you're using pip to install your modules, just pip show $module
the location is returned.
As Yaron mentioned, there isn't any difference between where
and filter
.
filter
is an overloaded method that takes a column or string argument. The performance is the same, regardless of the syntax you use.
We can use explain()
to see that all the different filtering syntaxes generate the same Physical Plan. Suppose you have a dataset with person_name
and person_country
columns. All of the following code snippets will return the same Physical Plan below:
df.where("person_country = 'Cuba'").explain()
df.where($"person_country" === "Cuba").explain()
df.where('person_country === "Cuba").explain()
df.filter("person_country = 'Cuba'").explain()
These all return this Physical Plan:
== Physical Plan ==
*(1) Project [person_name#152, person_country#153]
+- *(1) Filter (isnotnull(person_country#153) && (person_country#153 = Cuba))
+- *(1) FileScan csv [person_name#152,person_country#153] Batched: false, Format: CSV, Location: InMemoryFileIndex[file:/Users/matthewpowers/Documents/code/my_apps/mungingdata/spark2/src/test/re..., PartitionFilters: [], PushedFilters: [IsNotNull(person_country), EqualTo(person_country,Cuba)], ReadSchema: struct<person_name:string,person_country:string>
The syntax doesn't change how filters are executed under the hood, but the file format / database that a query is executed on does. Spark will execute the same query differently on Postgres (predicate pushdown filtering is supported), Parquet (column pruning), and CSV files. See here for more details.
You get this message in the logs, because you do something that is not allowed in the current state of your MediaPlayer instance.
Therefore you should always register an error handler to catch those things (as @tidbeck suggested).
At first, I advice you to take a look at the documentation for the MediaPlayer
class and get an understanding of what that with states means. See: http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram
Your mistake here could well be one of the common ones, the others wrote here, but in general, I would take a look at the documentation of what methods are valid to call in what state: http://developer.android.com/reference/android/media/MediaPlayer.html#Valid_and_Invalid_States
In my example it was the method mediaPlayer.CurrentPosition
, that I called while the media player was in a state, where it was not allowed to call this property.
Audience. Functional testing is to assure members of the team producing the software that it does what they expect. Acceptance testing is to assure the consumer that it meets their needs.
Scope. Functional testing only tests the functionality of one component at a time. Acceptance testing covers any aspect of the product that matters to the consumer enough to test before accepting the software (i.e., anything worth the time or money it will take to test it to determine its acceptability).
Software can pass functional testing, integration testing, and system testing; only to fail acceptance tests when the customer discovers that the features just don't meet their needs. This would usually imply that someone screwed up on the spec. Software could also fail some functional tests, but pass acceptance testing because the customer is willing to deal with some functional bugs as long as the software does the core things they need acceptably well (beta software will often be accepted by a subset of users before it is completely functional).
The reason for this error occurs is that you are using the CryptoListPresenter _presenter
without initializing.
I found that CryptoListPresenter _presenter
would have to be initialized to fix because _presenter.loadCurrencies()
is passing through a null variable at the time of instantiation;
there are two ways to initialize
Can be initialized during an declaration, like this
CryptoListPresenter _presenter = CryptoListPresenter();
In the second, initializing(with assigning some value) it when initState
is called, which the framework will call this method once for each state object.
@override
void initState() {
_presenter = CryptoListPresenter(...);
}
A class that takes a required dependency as a constructor argument can only be instantiated if that argument is provided (you should have a guard clause to make sure the argument is not null.) A constructor therefore enforces the dependency requirement whether or not you're using Spring, making it container-agnostic.
If you use setter injection, the setter may or may not be called, so the instance may never be provided with its dependency. The only way to force the setter to be called is using @Required
or @Autowired
, which is specific to Spring and is therefore not container-agnostic.
So to keep your code independent of Spring, use constructor arguments for injection.
Update: Spring 4.3 will perform implicit injection in single-constructor scenarios, making your code more independent of Spring by potentially not requiring an @Autowired
annotation at all.
To kill the puma process first run
lsof -wni tcp:3000
to show what is using port 3000. Then use the PID that comes with the result to run the kill process.
For example after running lsof -wni tcp:3000 you might get something like
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ruby 3366 dummy 8u IPv4 16901 0t0 TCP 127.0.0.1:3000 (LISTEN)
Now run the following to kill the process. (where 3366 is the PID)
kill -9 3366

It is also possible to use FormData()
. But you need to set contentType
as false
:
var data = new FormData();
data.append('name', 'Bob');
function sendData() {
$.ajax({
url: '/helloworld',
type: 'POST',
contentType: false,
data: data,
dataType: 'json'
});
}
you can try:
services:
nameis:
container_name: hi_my
build: .
image: hi_my_nameis:v1.0.0
Adding dependencies didn't fix the issue at my end.
The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.
I removed the additional fields from the @Entity class and it worked.
Goodluck.

I'm pretty sure the terminal in OS X is just like unix, so the command would be:

I don't have a mac on me at the moment so someone correct me if I'm wrong.
NOTE - The whoami
utility has been obsoleted, and is equivalent to id -un
. It will give you the current user
All hover is doing behind the scenes is binding to the mouseover and mouseout property. I would bind and unbind your functions from those events individually.
For example, say you have the following html:
<a href="#" class="myLink">Link</a>
then your jQuery would be:
$(document).ready(function() {
function mouseOver()
{
$(this).css('color', 'red');
}
function mouseOut()
{
$(this).css('color', 'blue');
}
// either of these might work
$('.myLink').hover(mouseOver, mouseOut);
$('.myLink').mouseover(mouseOver).mouseout(mouseOut);
// otherwise use this
$('.myLink').bind('mouseover', mouseOver).bind('mouseout', mouseOut);
// then to unbind
$('.myLink').click(function(e) {
e.preventDefault();
$('.myLink').unbind('mouseover', mouseOver).unbind('mouseout', mouseOut);
});
});
Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.
Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:]
or [._:-]
, to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:]
, and I wouldn't call that unconventional.
Here you go:
var user = User as ClaimsPrincipal;
var identity = user.Identity as ClaimsIdentity;
var claim = (from c in user.Claims
where c.Type == ClaimTypes.UserData
select c).Single();
identity.RemoveClaim(claim);
taken from here.
sed -i 's/[^[:print:]]//' FILENAME
Also, this acts like dos2unix
As part of htmlAttributes,e.g.
Html.BeginForm(
action, controller, FormMethod.Post, new { enctype="multipart/form-data"})
Or you can pass null
for action and controller to get the same default target as for BeginForm() without any parameters:
Html.BeginForm(
null, null, FormMethod.Post, new { enctype="multipart/form-data"})
Oracle has a different syntax for parameters than Sql-Server. So use :
instead of @
using(var con=new OracleConnection(connectionString))
{
con.open();
var sql = "insert into users values (:id,:name,:surname,:username)";
using(var cmd = new OracleCommand(sql,con)
{
OracleParameter[] parameters = new OracleParameter[] {
new OracleParameter("id",1234),
new OracleParameter("name","John"),
new OracleParameter("surname","Doe"),
new OracleParameter("username","johnd")
};
cmd.Parameters.AddRange(parameters);
cmd.ExecuteNonQuery();
}
}
When using named parameters in an OracleCommand you must precede the parameter name with a colon (:).

Interesting question! While there are plenty of guides on horizontally and vertically centering a div, an authoritative treatment of the subject where the centered div is of an unpredetermined width is conspicuously absent.
Let's apply some basic constraints:
table-cell
, which is of questionable support statusGiven this, my entry into the fray is the use of the inline-block
display property to horizontally center the span within an absolutely positioned div of predetermined height, vertically centered within the parent container in the traditional top: 50%; margin-top: -123px
fashion.
Markup: div > div > span
CSS:
body > div { position: relative; height: XYZ; width: XYZ; }
div > div {
position: absolute;
top: 50%;
height: 30px;
margin-top: -15px;
text-align: center;}
div > span { display: inline-block; }
Source: http://jsfiddle.net/38EFb/
An alternate solution that doesn't require extraneous markups but that very likely produces more problems than it solves is to use the line-height property. Don't do this. But it is included here as an academic note: http://jsfiddle.net/gucwW/
If you want to go through each row(<tr>
), knowing/identifying the row(<tr>
), and iterate through each column(<td>
) of each row(<tr>
), then this is the way to go.
var table = document.getElementById("mytab1");
for (var i = 0, row; row = table.rows[i]; i++) {
//iterate through rows
//rows would be accessed using the "row" variable assigned in the for loop
for (var j = 0, col; col = row.cells[j]; j++) {
//iterate through columns
//columns would be accessed using the "col" variable assigned in the for loop
}
}
If you just want to go through the cells(<td>
), ignoring which row you're on, then this is the way to go.
var table = document.getElementById("mytab1");
for (var i = 0, cell; cell = table.cells[i]; i++) {
//iterate through cells
//cells would be accessed using the "cell" variable assigned in the for loop
}
Try downgrading your java version, this will happen when your systems java version isn't compatible with the one from android. Once you changed you the java version just run flutter doctor
it will automatically accepts the licenses.
The easiest way to match both
^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$
and
^[0-9]{3}-[0-9]{3}-[0-9]{4}$
is to use alternation ((...|...)
): specify them as two mostly-separate options:
^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$
By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234
, not (123)123-1234
. So you might want to write:
^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$
(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)
Fix for Android N & above: I had similar issue and mange to solve it by following steps described in https://developer.android.com/training/articles/security-config
But the config changes, without any complicated code logic, would only work on Android version 24 & above.
Fix for all version, including version < N: So for android lower then N (version 24) the solution is to via code changes as mentioned above.

I'm Daniel Stenberg.
I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.
I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.
Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.
Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.
Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.
At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.
Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.
Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?
Yes. So insanely much.
But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.
We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.
Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.
Yeah. For real.
Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.
But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.
curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.
While the results vary in this case because the column names are numbers, another way I've used is data.frame(rbind(mytable))
. Using the example from @X.X:
> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)
> freq_t
gear
cyl 3 4 5
4 1 8 2
6 2 4 1
8 12 0 2
> data.frame(rbind(freq_t))
X3 X4 X5
4 1 8 2
6 2 4 1
8 12 0 2
If the column names do not start with numbers, the X
won't get added to the front of them.

If you want use custom roles, you can do this:
CustomRoles
class:
public static class CustomRoles
{
public const string Administrator = "Administrador";
public const string User = "Usuario";
}
Usage
[Authorize(Roles = CustomRoles.Administrator +","+ CustomRoles.User)]
If you have few roles, maybe you can combine them (for clarity) like this:
public static class CustomRoles
{
public const string Administrator = "Administrador";
public const string User = "Usuario";
public const string AdministratorOrUser = Administrator + "," + User;
}
Usage
[Authorize(Roles = CustomRoles.AdministratorOrUser)]

Create the branch on your local machine and switch in this branch :
$ git checkout -b [name_of_your_new_branch]
Push the branch on github :
$ git push origin [name_of_your_new_branch]
When you want to commit something in your branch, be sure to be in your branch.
You can see all branches created by using :
$ git branch
Which will show :
* approval_messages
master
master_clean
Add a new remote for your branch :
$ git remote add [name_of_your_remote]
Push changes from your commit into your branch :
$ git push origin [name_of_your_remote]
Update your branch when the original branch from official repository has been updated :
$ git fetch [name_of_your_remote]
Then you need to apply to merge changes, if your branch is derivated from develop you need to do :
$ git merge [name_of_your_remote]/develop
Delete a branch on your local filesystem :
$ git branch -d [name_of_your_new_branch]
To force the deletion of local branch on your filesystem :
$ git branch -D [name_of_your_new_branch]
Delete the branch on github :
$ git push origin :[name_of_your_new_branch]

and it worked.
Each version of the Android Gradle Plugin now has a default version of the build tools. For the best performance, you should use the latest possible version of both Gradle and the plugin. You recive this warning in case if you use latest gradle plugin but not use latest SDK version. For example for Gradle plugin 3.2.0 (September 2018) you requires Gradle 4.6 or higher and SDK Build Tools 28.0.3 or higher.
Although you typically don't need to specify the build tools version, when using Android Gradle plugin 3.2.0 with renderscriptSupportModeEnabled set to true, you need to include the following in each module's build.gradle file: android.buildToolsVersion "28.0.3"

I came across this thread while working on my understanding of Cython. My extension to the original question might be of use to others working at the C / Cython interface. So this is the extension of the original question: how do I return a string from a C function, making it available to Cython & thus to Python?
For those not familiar with it, Cython allows you to statically type Python code that you need to speed up. So the process is, enjoy writing Python :), find its a bit slow somewhere, profile it, calve off a function or two and cythonize them. Wow. Close to C speed (it compiles to C) Fixed. Yay. The other use is importing C functions or libraries into Python as done here.
This will print a string and return the same or another string to Python. There are 3 files, the c file c_hello.c, the cython file sayhello.pyx, and the cython setup file sayhello.pyx. When they are compiled using python setup.py build_ext --inplace
they generate a shared library file that can be imported into python or ipython and the function sayhello.hello run.
c_hello.c
#include <stdio.h>
char *c_hello() {
char *mystr = "Hello World!\n";
return mystr;
// return "this string"; // alterative
}
sayhello.pyx
cdef extern from "c_hello.c":
cdef char* c_hello()
def hello():
return c_hello()
setup.py
from setuptools import setup
from setuptools.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize
ext_modules = cythonize([Extension("sayhello", ["sayhello.pyx"])])
setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)
9re created a simple utility to handle the heavy lifting of dealing with EXIF data and rotating images to their correct orientation.
You can find the utility code here: https://gist.github.com/9re/1990019
Simply download this, add it to your project's src
directory and use ExifUtil.rotateBitmap()
to get the correct orientation, like so:
String imagePath = photoFile.getAbsolutePath(); // photoFile is a File class.
Bitmap myBitmap = BitmapFactory.decodeFile(imagePath);
Bitmap orientedBitmap = ExifUtil.rotateBitmap(imagePath, myBitmap);

If you don't mind VBA, here is a function that will do it for you. Your call would be something like:
=CountRows(1:10)
Function CountRows(ByVal range As range) As Long
Application.ScreenUpdating = False
Dim row As range
Dim count As Long
For Each row In range.Rows
If (Application.WorksheetFunction.CountBlank(row)) - 256 <> 0 Then
count = count + 1
End If
Next
CountRows = count
Application.ScreenUpdating = True
End Function
How it works: I am exploiting the fact that there is a 256 row limit. The worksheet formula CountBlank will tell you how many cells in a row are blank. If the row has no cells with values, then it will be 256. So I just minus 256 and if it's not 0 then I know there is a cell somewhere that has some value.

OpenCL is an effort to make a cross-platform library capable of programming code suitable for, among other things, GPUs. It allows one to write the code without knowing what GPU it will run on, thereby making it easier to use some of the GPU's power without targeting several types of GPU specifically. I suspect it's not as performant as native GPU code (or as native as the GPU manufacturers will allow) but the tradeoff can be worth it for some applications.
It's still in its relatively early stages (1.1 as of this answer), but has gained some traction in the industry - for instance it is natively supported on OS X 10.5 and above.
Unless I'm misunderstanding, you lost your .ssh
directory containing your private key on your local machine and so you want to remove the public key which was on a server and which allowed key-based login.
In that case, it will be stored in the .ssh/authorized_keys
file in your home directory on the server. You can just edit this file with a text editor and delete the relevant line if you can identify it (even easier if it's the only entry!).
I hope that key wasn't your only method of access to the server and you have some other way of logging in and editing the file. You can either manually add a new public key to authorised_keys
file or use ssh-copy-id
. Either way, you'll need password authentication set up for your account on the server, or some other identity or access method to get to the authorized_keys
file on the server.
ssh-add
adds identities to your SSH agent which handles management of your identities locally and "the connection to the agent is forwarded over SSH remote logins, and the user can thus use the privileges given by the identities anywhere in the network in a secure way." (man page), so I don't think it's what you want in this case. It doesn't have any way to get your public key onto a server without you having access to said server via an SSH login as far as I know.
.NET Core 3 will have support for creating Windows desktop applications. I watched a demo of the technology yesterday during the .NET Conference.
This is the only blog post I could find, but it does illustrate the point: .NET Core 3 and Support for Windows Desktop Applications
For unsigned APK: Simply set signingConfig null. It will give you appName-debug-unsigned.apk
debug {
signingConfig null
}
And build from Build menu. Enjoy

I needed something similar, so I wrote https://github.com/beradrian/jsbandwidth. This is a rewrite of https://code.google.com/p/jsbandwidth/.
The idea is to make two calls through Ajax, one to download and the other to upload through POST.
It should work with both jQuery.ajax
or Angular $http
.
this short code worked for me:
Configuration wConfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup wServiceSection = ServiceModelSectionGroup.GetSectionGroup(wConfig);
ClientSection wClientSection = wServiceSection.Client;
wClientSection.Endpoints[0].Address = <your address>;
wConfig.Save();
Of course you have to create the ServiceClient proxy AFTER the config has changed. You also need to reference the System.Configuration and System.ServiceModel assemblies to make this work.
Cheers

this return np array of your list as float
you also can set 'dtype' as int

I know I'm late to the party but I thought I'd add what I ended up using for this - which is to simply check if the file upload input does not contain a truthy value with the not operator & JQuery like so:
if (!$('#videoUploadFile').val()) {
alert('Please Upload File');
}
Note that if this is in a form, you may also want to wrap it with the following handler to prevent the form from submitting:
$(document).on("click", ":submit", function (e) {
if (!$('#videoUploadFile').val()) {
e.preventDefault();
alert('Please Upload File');
}
}
Both of the following code will work fine for removing highchart.com from the chart:-

This is (rather ridiculously) a private API.
The following two methods are private and sent to the UITableView's delegate:
-(NSString *)tableView:(UITableView *)tableView titleForSwipeAccessoryButtonForRowAtIndexPath:(NSIndexPath *)indexPath;
-(void)tableView:(UITableView *)tableView swipeAccessoryButtonPushedForRowAtIndexPath:(NSIndexPath *)indexPath;
They are pretty self explanatory.
if I got it right, you can try

I did change OS on my server quite a few times trying to get the most comfortable system.
It used to work very well most of the time but lastly I got this 502 Gateway error.
I use a php fpm socket for each account instead of keeping the same one for all. So if one crashes, at least the other applications keep running.
I used to have user and group www-data. But this changed on my Debian 8 with latest Nginx 1.8 and php5-fpm.
The default user is nginx and so is the group. To be sure of this, the best way is to check the /etc/group and /etc/passwd files. These can't lie.
It is there I found that now I have nginx in both and no longer www-data.
Maybe this can help some people still trying to find out why the error message keeps coming up.
It worked for me.
For the case: "This has not been pushed, only committed." - if you use IntelliJ (or another JetBrains IDE) and you haven't pushed changes yet you can do next.
Done.
This will "uncommit" your changes and return your git status to the point before your last local commit. You will not lose any changes you made.

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").
From the command line, you can type
python setup.py --help
...to get a list of commands. What you are looking to do is...

yes, you can remove the files from the git repository. But if your team all use the same IDE or you are by yourself, you probably don't want to do that. For yourself, you want to have an ok starting point to resume working, for your teammates as well.
I answered a virtually identical question just the other day: Save CSV files into mysql database
MySQL has a feature LOAD DATA INFILE
, which allows it to import a CSV file directly in a single SQL query, without needing it to be processed in a loop via your PHP program at all.
Simple example:
<?php
$query = <<<eof
LOAD DATA INFILE '$fileName'
INTO TABLE tableName
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
(field1,field2,field3,etc)
eof;
$db->query($query);
?>
It's as simple as that.
No loops, no fuss. And much much quicker than parsing it in PHP.

I also thought this would work but it's misleading:
myStruct _m1 = {0};
When I tried this:
myStruct _m1 = {0xff};
Only the 1st byte was set to 0xff
, the remaining ones were set to 0
. So I wouldn't get into the habit of using this.
Port Access
Firewalls and other security tools may prevent RabbitMQ from binding to a port. When that happens, RabbitMQ will fail to start. Make sure the following ports can be opened:
4369: epmd, a peer discovery service used by RabbitMQ nodes and CLI tools
5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS
25672: used by Erlang distribution for inter-node and CLI tools communication and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). See networking guide for details.
15672: HTTP API clients and rabbitmqadmin (only if the management plugin is enabled)
61613, 61614: STOMP clients without and with TLS (only if the STOMP plugin is enabled)
1883, 8883: (MQTT clients without and with TLS, if the MQTT plugin is enabled
15674: STOMP-over-WebSockets clients (only if the Web STOMP plugin is enabled)
15675: MQTT-over-WebSockets clients (only if the Web MQTT plugin is enabled)

Use tr:first-child
to take the first tr
:
.category_table tr:first-child td {
vertical-align: top;
}
If you have nested tables, and you don't want to apply styles to the inner rows, add some child selectors so only the top-level td
s in the first top-level tr
get the styles:
.category_table > tbody > tr:first-child > td {
vertical-align: top;
}
Use System.Data
namespace then you will get .AsEnumerable()
.
I prefer this method as it doesn't require manually emitting markup. I use this because I'm rendering Razor Pages to strings and sending them out via email, which is an environment where the white-space styling won't always work.

IHtmlContent br = brTag.RenderSelfClosingTag();
HtmlContentBuilder htmlContent = new HtmlContentBuilder();
// JAS: On the off chance a browser is using LF instead of CRLF we strip out CR before splitting on LF.
string lfContent = content.Replace("\r", string.Empty, StringComparison.InvariantCulture);
string[] lines = lfContent.Split('\n', StringSplitOptions.None);
foreach(string line in lines)
{
_ = htmlContent.Append(line);
_ = htmlContent.AppendHtml(br);
}
return htmlContent;
}
The cause is the difference between how a Windows-based based OS and a Unix based OS store the end-of-line markers.
Windows based operating systems, thanks to their DOS heritage, store an end-of-line as a pair of characters - 0x0D0A
(carriage return + line feed). Unix-based operating systems just use 0x0A
(a line feed). The ^M
you're seeing is a visual representation of 0x0D
(a carriage return).
dos2unix will help with this. You probably also need to adjust the source of the scripts to be 'Unix-friendly'.
The RFCs are known not to reflect reality.

1) DO NOT generate a new ssh key by using command ssh-keygen -t rsa -C"[email protected]"
, you can delete existing SSH keys.
2) but use Git GUI, -> "Help" -> "Show ssh key" -> "Generate key", the key will saved to ssh automatically and no need to use ssh-add

This should help : http://www.w3.org/International/articles/language-tags/
The golden rule when creating language tags is to keep the tag as short as possible. Avoid region, script or other subtags except where they add useful distinguishing information. For instance, use ja for Japanese and not ja-JP, unless there is a particular reason that you need to say that this is Japanese as spoken in Japan, rather than elsewhere.
The list below shows the various types of subtag that are available. We will work our way through these and how they are used in the sections that follow.

I originally used Plantface's answer, but I didn't like how the syntax looked in my view.
I reworked it to use $q.defer to post-process the data and return a list on unique teams, which is then uses as the filter.
http://plnkr.co/edit/waWv1donzEMdsNMlMHBa?p=preview
<ul>
<li ng-repeat="team in teams">{{team}}
<ul>
<li ng-repeat="player in players | filter: {team: team}">{{player.name}}</li>
</ul>
</li>
</ul>
app.controller('MainCtrl', function($scope, $q) {
$scope.players = []; // omitted from SO for brevity
// create a deferred object to be resolved later
var teamsDeferred = $q.defer();
// return a promise. The promise says, "I promise that I'll give you your
// data as soon as I have it (which is when I am resolved)".
$scope.teams = teamsDeferred.promise;
// create a list of unique teams. unique() definition omitted from SO for brevity
var uniqueTeams = unique($scope.players, 'team');
// resolve the deferred object with the unique teams
// this will trigger an update on the view
teamsDeferred.resolve(uniqueTeams);
});
I find this one works well for a "FullName":
([a-z',.-]+( [a-z',.-]+)*){1,70}/
You can use following css to make an element middle aligned styled with position: absolute
:
.element {
transform: translateX(-50%);
position: absolute;
left: 50%;
}
With CSS having only left: 50%
we will have following effect:
While combining left: 50%
with transform: translate(-50%)
we will have following:
.hero { _x000D_
background-color: #e15915;_x000D_
position: relative;_x000D_
height: 320px;_x000D_
width: 100%;_x000D_
}_x000D_
_x000D_
_x000D_
.hero:after {_x000D_
border-right: solid 50px transparent;_x000D_
border-left: solid 50px transparent;_x000D_
border-top: solid 50px #e15915;_x000D_
transform: translateX(-50%);_x000D_
position: absolute;_x000D_

The bash way - convert the dates into %y%m%d format and then you can do this straight from the command line:
echo $(( ($(date --date="031122" +%s) - $(date --date="021020" +%s) )/(60*60*24) ))
As of Python 3.4 one can use the pathlib module to solve this.
If you happen to be on an older version, you can use the backported version found here
Let's assume you are not in the root path (just to add a bit of difficulty to it) you want to rename, and have to provide a full path, we can look at this:
some_path = 'a/b/c/the_file.extension'
So, you can take your path and create a Path
object out of it:
from pathlib import Path
p = Path(some_path)
Just to provide some information around this object we have now, we can extract things out of it. For example, if for whatever reason we want to rename the file by modifying the filename from the_file
to the_file_1
, then we can get the filename part:
name_without_extension = p.stem
And still hold the extension in hand as well:
ext = p.suffix
We can perform our modification with a simple string manipulation:
Python 3.6 and greater make use of f-strings!
new_file_name = f"{name_without_extension}_1"
Otherwise:
new_file_name = "{}_{}".format(name_without_extension, 1)
And now we can perform our rename by calling the rename
method on the path object we created and appending the ext
to complete the proper rename structure we want:
p.rename(Path(p.parent, new_file_name + ext))
More shortly to showcase its simplicity:
Python 3.6+:
from pathlib import Path
p = Path(some_path)
p.rename(Path(p.parent, f"{p.stem}_1_{p.suffix}"))
Versions less than Python 3.6 use the string format method instead:
from pathlib import Path
p = Path(some_path)
p.rename(Path(p.parent, "{}_{}_{}".format(p.stem, 1, p.suffix))
As said a previous answer, you can run the command
jest -t 'fix-order-test'
If you have an it
inside of a describe
block, you have to run
jest -t '<describeString> <itString>'
There is a cleaner way with just one header file so it is simpler to maintain. In the header with the global variables prefix each declaration with a keyword (I use common) then in just one source file include it like this
#define common
#include "globals.h"
#undef common
and any other source files like this
#define common extern
#include "globals.h"
#undef common
Just make sure you don't initialise any of the variables in the globals.h file or the linker will still complain as an initialised variable is not treated as external even with the extern keyword. The global.h file looks similar to this
#pragma once
common int globala;
common int globalb;
etc.
seems to work for any type of declaration. Don't use the common keyword on #define of course.

Just to add to others, a note specific to forking.
It's good to realize that technically, cloning the repo and forking the repo are the same thing. Do:
git clone $some_other_repo
and you can tap yourself on the back---you have just forked some other repo.
Git, as a VCS, is in fact all about cloning forking. Apart from "just browsing" using remote UI such as cgit, there is very little to do with git repo that does not involve forking cloning the repo at some point.
However,
when someone says I forked repo X, they mean that they have created a clone of the repo somewhere else with intention to expose it to others, for example to show some experiments, or to apply different access control mechanism (eg. to allow people without Github access but with company internal account to collaborate).
Facts that: the repo is most probably created with other command than
git clone
, that it's most probably hosted somewhere on a server as
opposed to somebody's laptop, and most probably has slightly different
format (it's a "bare repo", ie. without working tree) are all just
technical details.
The fact that it will most probably contain different set of branches, tags or commits is most probably the reason why they did it in the first place.
(What Github does when you click "fork", is just cloning with added sugar: it clones the repo for you, puts it under your account, records the "forked from" somewhere, adds remote named "upstream", and most importantly, plays the nice animation.)
When someone says I cloned repo X, they mean that they have created a clone of the repo locally on their laptop or desktop with intention study it, play with it, contribute to it, or build something from source code in it.
The beauty of Git is that it makes this all perfectly fit together: all these repos share the common part of block commit chain so it's possible to safely (see note below) merge changes back and forth between all these repos as you see fit.
Note: "safely" as long as you don't rewrite the common part of the chain, and as long as the changes are not conflicting.
First of all, you need to login as root and than go to /etc directory and execute some commands which are given below.
[root@localhost~]# cd /etc
[root@localhost /etc]# vi sudoers
and enter this line at the end
kundan ALL=NOPASSWD: ALL
where kundan is the username and than save it. and then try to transfer the file and add sudo
as a prefix to the command you want to execute:
sudo cp hello.txt /home/rahul/program/
where rahul is the second user in the same server.
As documented under CREATE TABLE
Syntax:
Note
The olderTYPE
option was synonymous withENGINE
.TYPE
was deprecated in MySQL 4.0 and removed in MySQL 5.5. When upgrading to MySQL 5.5 or later, you must convert existing applications that rely onTYPE
to useENGINE
instead.
Therefore, you want:
CREATE TABLE dave_bannedwords(
id INT(11) NOT NULL AUTO_INCREMENT,
word VARCHAR(60) NOT NULL DEFAULT '',
PRIMARY KEY (id),
KEY id(id) -- this is superfluous in the presence of your PK, ergo unnecessary
) ENGINE = MyISAM ;
perhaps this is what you're looking for: https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/colors.xml
It's not clear exactly what you want to do with the index of a substring [update: it is clearer now - thanks] but you may be able to use the function substring-after
or substring-before
:
substring-before('My name is Fred', 'Fred')
returns 'My name is '
.
If you need more detailed control, the substring()
function can take two or three arguments: string, starting-index, length. Omit length to get the whole rest of the string.
There is no index-of()
function for strings in XPath (only for sequences, in XPath 2.0). You can use string-length(substring-before($string, $substring))+1
if you specifically need the position.
There is also contains($string, $substring)
. These are all documented here. In XPath 2.0 you can use regular expression matching.
(XSLT mostly uses XPath for selecting nodes and processing values, so this is actually more of an XPath question. I tagged it thus.)
You need to configure babel correctly in your project to use export default and export const foo
npm install --save-dev @babel/plugin-proposal-export-default-from
then add below configration in .babelrc
"plugins": [
"@babel/plugin-proposal-export-default-from"
]
In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.
I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?
Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,
There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.
The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).
Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.
Add .*
to s
in your first line.
Try:
DELETE s.* FROM spawnlist s
INNER JOIN npc n ON s.npc_templateid = n.idTemplate
WHERE (n.type = "monster");
This seems like a common misunderstanding. In Oracle's JVM, the permanent generation is not part of the heap. It's a separate space for class definitions and related data. In Java 6 and earlier, interned strings were also stored in the permanent generation. In Java 7, interned strings are stored in the main object heap.
Here is a good post on permanent generation.
I like the descriptions given for each space in Oracle's guide on JConsole:
For the HotSpot Java VM, the memory pools for serial garbage collection are the following.
- Eden Space (heap): The pool from which memory is initially allocated for most objects.
- Survivor Space (heap): The pool containing objects that have survived the garbage collection of the Eden space.
- Tenured Generation (heap): The pool containing objects that have existed for some time in the survivor space.
- Permanent Generation (non-heap): The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.
- Code Cache (non-heap): The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.
Java uses generational garbage collection. This means that if you have an object foo (which is an instance of some class), the more garbage collection events it survives (if there are still references to it), the further it gets promoted. It starts in the young generation (which itself is divided into multiple spaces - Eden and Survivor) and would eventually end up in the tenured generation if it survived long enough.
