You can also use a docblock annotation until PHPUnit 9 is released:
class ExceptionTest extends PHPUnit_Framework_TestCase
{
/**
* @expectedException InvalidArgumentException
*/
public function testException()
{
...
}
}
For PHP 5.5+ (especially with namespaced code), I now prefer using ::class
After installing pipenv (sudo pip install pipenv
), I kept getting the "Command Not Found" error when attempting to run the pipenv shell
command.
I finally fixed it with the following code:
pip3 install pipenv
pipenv shell
You can try this:
CommandArgument='<%# "scrapid=" + Eval("ScrapId")+"&"+"UserId="+ Eval("UserId")%>'
you can use this code .may be solve the problem
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://192.168.43.1:6789/mobile_base/test.apk"));

I'd like to contribute to all of the great answers in this thread with a convincing example to disperse any remaining misunderstanding.
Given two source files, such as:
inline111.cpp:
#include <iostream>
void bar();
inline int fun() {
return 111;
}
int main() {
std::cout << "inline111: fun() = " << fun() << ", &fun = " << (void*) &fun;
bar();
}
inline222.cpp:
#include <iostream>
inline int fun() {
return 222;
}
void bar() {
std::cout << "inline222: fun() = " << fun() << ", &fun = " << (void*) &fun;
}
Case A:
Compile:
g++ -std=c++11 inline111.cpp inline222.cpp
Output:
inline111: fun() = 111, &fun = 0x4029a0
inline222: fun() = 111, &fun = 0x4029a0
Discussion:
Even thou you ought to have identical definitions of your inline functions, C++ compiler does not flag it if that is not the case (actually, due to separate compilation it has no ways to check it). It is your own duty to ensure this!
Linker does not complain about One Definition Rule, as fun()
is declared as inline
. However, because inline111.cpp is the first translation unit (which actually calls fun()
) processed by compiler, the compiler instantiates fun()
upon its first call-encounter in inline111.cpp. If compiler decides not to expand fun()
upon its call from anywhere else in your program (e.g. from inline222.cpp), the call to fun()
will always be linked to its instance produced from inline111.cpp (the call to fun()
inside inline222.cpp may also produce an instance in that translation unit, but it will remain unlinked). Indeed, that is evident from the identical &fun = 0x4029a0
print-outs.
Finally, despite the inline
suggestion to the compiler to actually expand the one-liner fun()
, it ignores your suggestion completely, which is clear because fun() = 111
in both of the lines.
Case B:
Compile (notice reverse order):
g++ -std=c++11 inline222.cpp inline111.cpp
Output:
inline111: fun() = 222, &fun = 0x402980
inline222: fun() = 222, &fun = 0x402980
Discussion:
This case asserts what have been discussed in Case A.
Notice an important point, that if you comment out the actual call to fun()
in inline222.cpp (e.g. comment out cout
-statement in inline222.cpp completely) then, despite the compilation order of your translation units, fun()
will be instantiated upon it's first call encounter in inline111.cpp, resulting in print-out for Case B as inline111: fun() = 111, &fun = 0x402980
.
Case C:
Compile (notice -O2):
g++ -std=c++11 -O2 inline222.cpp inline111.cpp
or
g++ -std=c++11 -O2 inline111.cpp inline222.cpp
Output:
inline111: fun() = 111, &fun = 0x402900
inline222: fun() = 222, &fun = 0x402900
Discussion:
-O2
optimization encourages compiler to actually expand the functions that can be inlined (Notice also that -fno-inline
is default without optimization options). As is evident from the outprint here, the fun()
has actually been inline expanded (according to its definition in that particular translation unit), resulting in two different fun()
print-outs. Despite this, there is still only one globally linked instance of fun()
(as required by the standard), as is evident from identical &fun
print-out.I used below code and it's working fine for me. :
let jsonText = "{\"userName\":\"Bhavsang\"}"
var dictonary:NSDictionary?
if let data = jsonText.dataUsingEncoding(NSUTF8StringEncoding) {
do {
dictonary = try NSJSONSerialization.JSONObjectWithData(data, options: [.allowFragments]) as? [String:AnyObject]
if let myDictionary = dictonary
{
print(" User name is: \(myDictionary["userName"]!)")
}
} catch let error as NSError {
print(error)
}
}
body, html {
width: 100%;
height: 100%;
}
Worked for me :)
I like to create a boolean
and then use that in a logical if
.
//kick unvalidated users to the login page
var onLoginPage = (window.location.href.indexOf("login") > -1);
if (!onLoginPage) {
console.log('redirected to login page');
window.location = "/login";
} else {
console.log('already on the login page');
}
This should do it (where df is your dataframe)
df$JoiningDate <- as.Date(df$JoiningDate , format = "%m/%d/%y")
df[order(df$JoiningDate ),]
xcopy e:\source_folder f:\destination_folder /e /i /h
The /h is just in case there are hidden files. The /i creates a destination folder if there are muliple source files.
since the data ex1221new was not given, so I have created a dummy data and added it to a data frame. Also, the question which was asked has few changes in codes like then ggplot package has deprecated the use of
"scale_area()" and nows uses scale_size_area()
"opts()" has changed to theme()
In my answer,I have stored the plot in mygraph variable and then I have used
mygraph$labels$x="Discharge of materials" #changes x axis title
mygraph$labels$y="Area Affected" # changes y axis title
And the work is done. Below is the complete answer.
install.packages("Sleuth2")
library(Sleuth2)
library(ggplot2)
ex1221new<-data.frame(Discharge<-c(100:109),Area<-c(120:129),NO3<-seq(2,5,length.out = 10))
discharge<-ex1221new$Discharge
area<-ex1221new$Area
nitrogen<-ex1221new$NO3
p <- ggplot(ex1221new, aes(discharge, area), main="Point")
mygraph<-p + geom_point(aes(size= nitrogen)) +
scale_size_area() + ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")+
theme(
plot.title = element_text(color="Blue", size=30, hjust = 0.5),
# change the styling of both the axis simultaneously from this-
axis.title = element_text(color = "Green", size = 20, family="Courier",)
# you can change the axis title from the code below
mygraph$labels$x="Discharge of materials" #changes x axis title
mygraph$labels$y="Area Affected" # changes y axis title
mygraph
Also, you can change the labels title from the same formula used above -
mygraph$labels$size= "N2" #size contains the nitrogen level
Exact same thing, just omit the -c
option. Apache's docs on it here.
htpasswd /etc/apache2/.htpasswd newuser
Also, htpasswd
typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).
If you want to use std::string
reliably, you must #include <string>
.
I face the similar issue and surprisingly meta tag didn't work this time. Turns out the company I currently cooperate with has this enterprise mode setting which has priority over meta tag.
We can't change the setting cause policy issue. Luckily I don't really need any fancy features but basic usage of jQuery so my final solution is to switch its version to 1.12 for better compatibility.

I found this problem too. Because centos service depend on multi-user.target for none desktop Cenots 7.2. so I delete multi-user.target from my .service file. It had missed.
The answer here explain it very detailed and brilliantly, the answer contains:
In short; body-parser extracts the entire body portion of an incoming request stream and exposes it on
req.body
as something easier to interface with. You don't need it per se, because you could do all of that yourself. However, it will most likely do what you want and save you the trouble.
To go a little more in depth; body-parser gives you a middleware which uses nodejs/zlib to unzip the incoming request data if it's zipped and stream-utils/raw-body to await the full, raw contents of the request body before "parsing it" (this means that if you weren't going to use the request body, you just wasted some time).
After having the raw contents, body-parser will parse it using one of four strategies, depending on the specific middleware you decided to use:
bodyParser.raw(): Doesn't actually parse the body, but just exposes the buffered up contents from before in a Buffer on
req.body
.bodyParser.text(): Reads the buffer as plain text and exposes the resulting string on req.body.
bodyParser.urlencoded(): Parses the text as URL encoded data (which is how browsers tend to send form data from regular forms set to POST) and exposes the resulting object (containing the keys and values) on
req.body
. For comparison; in PHP all of this is automatically done and exposed in$_POST
.bodyParser.json(): Parses the text as JSON and exposes the resulting object on
req.body
.Only after setting the
req.body
to the desirable contents will it call the next middleware in the stack, which can then access the request data without having to think about how to unzip and parse it.
You can refer to body-parser github to read their documentation, it contains information regarding its working.

Using the Euler-Rodrigues formula:

def rotation_matrix(axis, theta):
"""

"""
axis = np.asarray(axis)
axis = axis / math.sqrt(np.dot(axis, axis))
a = math.cos(theta / 2.0)
b, c, d = -axis * math.sin(theta / 2.0)
aa, bb, cc, dd = a * a, b * b, c * c, d * d
bc, ad, ac, ab, bd, cd = b * c, a * d, a * c, a * b, b * d, c * d
return np.array([[aa + bb - cc - dd, 2 * (bc + ad), 2 * (bd - ac)],
[2 * (bc - ad), aa + cc - bb - dd, 2 * (cd + ab)],

Use the ViewPager.onPageChangeListener
:
viewPager.addOnPageChangeListener(new OnPageChangeListener() {

public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}
public void onPageSelected(int position) {
// Check if this is the page you want.

Instead of creating a crontab to run as the root user, create a crontab for the user that you want to run the script. In your case, crontab -u www-data -e
will edit the crontab for the www-data user. Just put your full command in there and remove it from the root user's crontab.
Share Any File as below ( Kotlin ) :
first create a folder named xml
in the res
folder and create a new XML Resource File named provider_paths.xml
and put the below code inside it :
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path
name="files"
path="."/>
<external-path
name="external_files"
path="."/>
</paths>
now go to the manifests
folder and open the AndroidManifest.xml
and then put the below code inside the <application>
tag :
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" /> // provider_paths.xml file path in this example
</provider>
now you put the below code in the setOnLongClickListener
:
share_btn.setOnClickListener {
try {
val file = File("pathOfFile")
if(file.exists()) {
val uri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", file)
val intent = Intent(Intent.ACTION_SEND)
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
intent.setType("*/*")
intent.putExtra(Intent.EXTRA_STREAM, uri)
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent)
}
} catch (e: java.lang.Exception) {
e.printStackTrace()
toast("Error")
}
}
I also know this has already been answered but I wrapped up the previous answers:
extension Bundle {
var releaseVersionNumber: String? {
return infoDictionary?["CFBundleShortVersionString"] as? String
}
var buildVersionNumber: String? {
return infoDictionary?["CFBundleVersion"] as? String
}
var releaseVersionNumberPretty: String {
return "v\(releaseVersionNumber ?? "1.0.0")"
}
}
Usage:
someLabel.text = Bundle.main.releaseVersionNumberPretty
Swift 3.1:
class func getVersion() -> String {
guard let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String else {
return "no version info"
}
return version
}
For older versions:
class func getVersion() -> String {
if let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as? String {
return version
}
return "no version info"
}
So if you want to set label text or want to use somewhere else;
self.labelVersion.text = getVersion()
You need to use the scrollTop
property.
document.getElementById('box').scrollTop
Just to rule out the possibility you aren't actually trying to see the fragment on a GET/POST and actually want to know how to access that part of a URI object you have within your server-side code, it is under Uri.Fragment (MSDN docs).
Combination of lambda and map function can also do the job:
list_ = ['a', 'b', 'b', 'c']
sum(map(lambda x: x=="b", list_))

C is not object oriented programming (OOP) language. So you can not use properties in OOP. Eg. There is no .length property in C. So you need to use loops for your task.

I would like to present a modified version of Vadim's solution. It helps to deal with asynchronous requests to write/modify json file. I know it wasn't a part of the original question but might be helpful for others.
In case of asynchronous file modification os.remove(filename)
will raise FileNotFoundError
if requests emerge frequently. To overcome this problem you can create temporary file with modified content and then rename it simultaneously replacing old version. This solution works fine both for synchronous and asynchronous cases.
import os, json, uuid
filename = 'data.json'
with open(filename, 'r') as f:
data = json.load(f)
data['id'] = 134 # <--- add `id` value.
# add, remove, modify content
# create randomly named temporary file to avoid
# interference with other thread/asynchronous request
tempfile = os.path.join(os.path.dirname(filename), str(uuid.uuid4()))
with open(tempfile, 'w') as f:
json.dump(data, f, indent=4)
# rename temporary file replacing old file
os.rename(tempfile, filename)
You can use Array.flat()

Using Linux or OSx, do what Sorin recommended but use port 465 instead. 25 is the generic SMTP port, but not what GMail uses. Also, I don't believe you want to use -starttls smtp
openssl s_client -connect smtp.gmail.com:465
You should get lots of information on the SSL session and the response:
220 mx.google.com ...
Type in
HELO smtp.gmail.com
and you'll receive:
250 mx.google.com at your service
From there it is not quite as straightforward as just sending SMTP messages because Gmail has protections in place to ensure you only send emails appearing to be from accounts that actually belong to you. Instead of typing in "Helo", use "Ehlo". I don't know much about SMTP so I cannot explain the difference, and don't have time to research much. Perhaps someone with more knowledge can explain.
Then, type "auth login" and you will receive the following:
334 VXNlcm5hbWU6
This is essentially the word "Username" encoded in Base 64. Using a Base 64 encoder such as this one, encode your user name and enter it. Do the same for your password, which is requested next. You should see:
235 2.7.0 Accepted
And that's it, you're logged in.
There is one more oddity to overcome if you're using OSx or Linux terminals. Just pressing the "ENTER" key does not apparently result in a CRLF which SMTP needs to end a message. You have to use "CTRL+V+ENTER". So, this should look like the following:
^M
.^M
250 2.0.0 OK

If you really want a vba solution you can loop through a range like this:
Sub Check()
Dim dat As Variant
Dim rng As Range
Dim i As Long
Set rng = Range("A1:A100")
dat = rng
For i = LBound(dat, 1) To UBound(dat, 1)
If dat(i, 1) <> "" Then
rng(i, 2).Value = "My Text"
End If
Next
End Sub
*EDIT*
Instead of using varients you can just loop through the range like this:
Sub Check()
Dim rng As Range
Dim i As Long
'Set the range in column A you want to loop through
Set rng = Range("A1:A100")
For Each cell In rng
'test if cell is empty
If cell.Value <> "" Then
'write to adjacent cell
cell.Offset(0, 1).Value = "My Text"
End If
Next
End Sub
This should work fine for you.
Write this code in the Page_Load
event of the page.
string ID = Request.QueryString["id"].ToString();
Response.Redirect("http://www.example.com/rendernews.php?id=" + ID);
Yes it is possible.
You need to use the getDeclaredField method (instead of the getField method), with the name of your private field:
Field privateField = Test.class.getDeclaredField("str");
Additionally, you need to set this Field to be accessible, if you want to access a private field:
privateField.setAccessible(true);
Once that's done, you can use the get method on the Field instance, to access the value of the str field.
This is a highly inefficient way of doing it. You can use the merge
statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.
MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
UPDATE SET l.studName = s.studName
WHERE l.studName != s.studName
WHEN NOT MATCHED THEN
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)
Make sure you commit
, once completed, in order to be able to see this in the database.
To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.
It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.
However, as I say this will not be as efficient as merge
.
declare
cursor c_data is
select b.rowid as rid, a.studId, a.studName
from student a
left outer join studLoad b
on a.studId = b.studId
and a.studName <> b.studName
;
type t__data is table of c_data%rowtype index by binary_integer;
t_data t__data;
begin
open c_data;
loop
fetch c_data bulk collect into t_data limit 10000;
exit when t_data.count = 0;
for idx in t_data.first .. t_data.last loop
if t_data(idx).rid is null then
insert into studLoad (studId, studName)
values (t_data(idx).studId, t_data(idx).studName);
else
update studLoad
set studName = t_data(idx).studName
where rowid = t_data(idx).rid
;
end if;
end loop;
end loop;
close c_data;
end;
/
There are a couple of options:
My preferred option would be the first one, if it's a short space, or the latter otherwise.
In case you don't want to include a big library like jQuery for something this simple, here's an alternative solution using built-in DOM methods:
// Check checkbox by id:_x000D_
document.querySelector('#radio_1').checked = true;_x000D_
_x000D_
// Check checkbox by value:_x000D_
document.querySelector('#type > [value="1"]').checked = true;_x000D_
_x000D_
// If this is the only input with a value of 1 on the page, you can leave out the #type >_x000D_
document.querySelector('[value="1"]').checked = true;
_x000D_
<form>_x000D_
<div id='type'>_x000D_
<input type='radio' id='radio_1' name='type' value='1' />_x000D_
<input type='radio' id='radio_2' name='type' value='2' />_x000D_
<input type='radio' id='radio_3' name='type' value='3' /> _x000D_
</div>_x000D_
</form>
_x000D_
This always running!
$sheet->getActiveSheet()->getStyle('A1')->getFill()->getStartColor()->setRGB('FF0000');
if (/(^|;)\s*visited=/.test(document.cookie)) {
alert("Hello again!");
} else {
document.cookie = "visited=true; max-age=" + 60 * 60 * 24 * 10; // 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and 10 days.
alert("This is your first time!");
}
is one way to do it. Note that document.cookie
is a magic property, so you don't have to worry about overwriting anything, either.
There are also more convenient libraries to work with cookies, and if you don’t need the information you’re storing sent to the server on every request, HTML5’s localStorage
and friends are convenient and useful.
If you want to keep the multi dimensional array, one should nest the array brackets. see example below where one is added to every element.
>>> a = [[1, 2], [3, 4]]
>>> [[col +1 for col in row] for row in a]
[[2, 3], [4, 5]]
>>> [col +1 for row in a for col in row]
[2, 3, 4, 5]
You can add the following lines to build.gradle
, **/*
excludes all the tests.
test {
exclude '**/*'
}

You can use Jackson API as well for this :
final String json = "....your json...";
final ObjectMapper mapper = new ObjectMapper();
final MapType type = mapper.getTypeFactory().constructMapType(
Map.class, String.class, Object.class);
final Map<String, Object> data = mapper.readValue(json, type);
All of the above didn't work for me - not sure why but:
componentDidMount(){
document.getElementById('HEADER').scrollIntoView();
}
worked, where HEADER is the id of my header element

It was a bit hard figure out how to get there from a dusty bug report, but:
It ships with IPython now!

, it'll pick up the latest version.
Try setting maxReceivedMessageSize on the server too, e.g. to 4MB:
<binding name="MyService.MyServiceBinding"
maxReceivedMessageSize="4194304">
The main reason the default (65535 I believe) is so low is to reduce the risk of Denial of Service (DoS) attacks. You need to set it bigger than the maximum request size on the server, and the maximum response size on the client. If you're in an Intranet environment, the risk of DoS attacks is probably low, so it's probably safe to use a value much higher than you expect to need.
By the way a couple of tips for troubleshooting problems connecting to WCF services:
Enable tracing on the server as described in this MSDN article.
Use an HTTP debugging tool such as Fiddler on the client to inspect the HTTP traffic.
Yes you can. I've used it with Word and PowerPoint. You will need Office 2010 client apps and SharePoint 2010 foundation at least. You must also allow editing without checking out on the document library.
It's quite cool, you can mark regions as 'locked' so no-one can change them and you can see what other people have changed every time you save your changes to the server. You also get to see who's working on the document from the Office app. The merging happens on SharePoint 2010.
import sys
def class_meta(frame):
class_context = '__module__' in frame.f_locals
assert class_context, 'Frame is not a class context'
module_name = frame.f_locals['__module__']
class_name = frame.f_code.co_name
return module_name, class_name
def print_class_path():
print('%s.%s' % class_meta(sys._getframe(1)))
class MyClass(object):

mail can represent quite a couple of programs on a linux system. What you want behind it is either sendmail or postfix. I recommend the latter.
You can install it via your favorite package manager. Then you have to configure it, and once you have done that, you can send email like this:
echo "My message" | mail -s subject [email protected]
See the manual for more information.
As far as configuring postfix goes, there's plenty of articles on the internet on how to do it. Unless you're on a public server with a registered domain, you generally want to forward the email to a SMTP server that you can send email from.
For gmail, for example, follow http://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/ or any other similar tutorial.
Why and when would we create a static constructor ...?
One specific reason to use a static constructor is to create a 'super enum' class. Here's a (simple, contrived) example:
public class Animals
{
private readonly string _description;
private readonly string _speciesBinomialName;
public string Description { get { return _description; } }
public string SpeciesBinomialName { get { return _speciesBinomialName; } }
private Animals(string description, string speciesBinomialName)
{
_description = description;
_speciesBinomialName = speciesBinomialName;
}
private static readonly Animals _dog;
private static readonly Animals _cat;
private static readonly Animals _boaConstrictor;
public static Animals Dog { get { return _dog; } }
public static Animals Cat { get { return _cat; } }
public static Animals BoaConstrictor { get { return _boaConstrictor; } }
static Animals()
{
_dog = new Animals("Man's best friend", "Canis familiaris");
_cat = new Animals("Small, typically furry, killer", "Felis catus");
_boaConstrictor = new Animals("Large, heavy-bodied snake", "Boa constrictor");
}
}
You'd use it very similarly (in syntactical appearance) to any other enum:
Animals.Dog
The advantage of this over a regular enum
is that you can encapsulate related info easily. One disadvantage is that you can't use these values in a switch
statement (because it requires constant values).
SELECT Cast(Round(123.456,2,1) as decimal(18,2))
At the time the script is executed, the button does not exist because the DOM is not fully loaded. The easiest solution would be to put the script block after the form.
Another solution would be to capture the window.onload
event or use the jQuery library (overkill if you only have this one JavaScript).

self.navigationController != nil would mean it's in a navigation stack.
In order to handle the case that the current view controller is pushed while the navigation controller is presented modally, I have added some lines of code to check if the current view controller is the root controller in the navigation stack .
extension UIViewController {
var isModal: Bool {
if let index = navigationController?.viewControllers.firstIndex(of: self), index > 0 {
return false
} else if presentingViewController != nil {

} else if let navigationController = navigationController, navigationController.presentingViewController?.presentedViewController == navigationController {
return true
} else if let tabBarController = tabBarController, tabBarController.presentingViewController is UITabBarController {
return true

Both the two most upvoted answers are wrong. It should have nothing to do with "store different/multiple languages". You can support Spanish characters like ñ
and English, with just common varchar
field and Latin1_General_CI_AS
COLLATION
, e.g.
Short Version
You should use NVARCHAR
/NCHAR
whenever the ENCODING
, which is determined by COLLATION
of the field, doesn't support the characters needed.
Also, depending on the SQL Server version, you can use specific COLLATIONs
, like Latin1_General_100_CI_AS_SC_UTF8
which is available since SQL Server 2019. Setting this collation on a VARCHAR
field (or entire table/database), will use UTF-8
ENCODING
for storing and handling the data on that field, allowing fully support UNICODE
characters, and hence any languages embraced by it.
To FULLY UNDERSTAND:
To fully understand what I'm about to explain, it's mandatory to have the concepts of UNICODE
, ENCODING
and COLLATION
all extremely clear in your head. If you don't, then first take a look below at my humble and simplified explanation on "What is UNICODE, ENCODING, COLLATION and UTF-8, and how they are related" section and supplied documentation links. Also, everything I say here is specific to Microsoft SQL Server
, and how it stores and handles data in char
/nchar
and varchar
/nvarchar
fields.
Let's say we wanna store a peculiar text on our MSSQL Server database. It could be an Instagram comment as "I love stackoverflow! ".
The plain English part would be perfectly supported even by ASCII, but since there are also an emoji, which is a character specified in the UNICODE
standard, we need an ENCODING
that supports this Unicode character.
MSSQL Server uses the COLLATION
to determine what ENCODING
is used on char
/nchar
/varchar
/nvarchar
fields. So, differently than a lot think, COLLATION
is not only about sorting and comparing data, but also about ENCODING
, and by consequence: how our data will be stored!
So, HOW WE KNOW WHAT IS THE ENCODING USED BY OUR COLLATION? With this:
SELECT COLLATIONPROPERTY( 'Latin1_General_CI_AI' , 'CodePage' ) AS [CodePage]
--returns 1252
This simple SQL returns the Windows Code Page
for a COLLATION
. A Windows Code Page
is nothing more than another mapping to ENCODINGs
. For the Latin1_General_CI_AI
COLLATION
it returns the Windows Code Page
code 1252
, that maps to Windows-1252
ENCODING
.
So, for a varchar
column, with Latin1_General_CI_AI
COLLATION
, this field will handle its data using the Windows-1252
ENCODING
, and only correctly store characters supported by this encoding.
If we check the Windows-1252 ENCODING
specification Character List for Windows-1252, we will find out that this encoding won't support our emoji character. And if we still try it out:
OK, SO HOW CAN WE SOLVE THIS?? Actually, it depends, and that is GOOD!
NCHAR
/NVARCHAR
Before SQL Server 2019 all we had was NCHAR
and NVARCHAR
fields. Some say they are UNICODE
fields. THAT IS WRONG!. Again, it depends on the field's COLLATION
and also SQLServer Version.
Microsoft's "nchar and nvarchar (Transact-SQL)" documentation specifies perfectly:
Starting with SQL Server 2012 (11.x), when a Supplementary Character (SC) enabled collation is used, these data types store the full range of Unicode character data and use the UTF-16 character encoding. If a non-SC collation is specified, then these data types store only the subset of character data supported by the UCS-2 character encoding.
In other words, if we use SQL Server older that 2012, like SQL Server 2008 R2 for example, the ENCODING
for those fields will use UCS-2 ENCODING
which support a subset of UNICODE
. But if we use SQL Server 2012 or newer, and define a COLLATION
that has Supplementary Character
enabled, than with our field will use the UTF-16
ENCODING
, that fully supports UNICODE
.
BUT WHAIT, THERE IS MORE! WE CAN USE UTF-8 NOW!!
CHAR
/VARCHAR
Starting with SQL Server 2019, WE CAN USE CHAR
/VARCHAR
fields and still fully support UNICODE
using UTF-8
ENCODING
!!!
From Microsoft's "char and varchar (Transact-SQL)" documentation:
Starting with SQL Server 2019 (15.x), when a UTF-8 enabled collation is used, these data types store the full range of Unicode character data and use the UTF-8 character encoding. If a non-UTF-8 collation is specified, then these data types store only a subset of characters supported by the corresponding code page of that collation.
Again, in other words, if we use SQL Server older that 2019, like SQL Server 2008 R2 for example, we need to check the ENCODING
using the method explained before. But if we use SQL Server 2019 or newer, and define a COLLATION
like Latin1_General_100_CI_AS_SC_UTF8
, then our field will use UTF-8
ENCODING
which is by far the most used and efficient encoding that supports all the UNICODE
characters.
Bonus Information:
Regarding the OP's observation on "I have seen that most of the European languages (German, Italian, English, ...) are fine in the same database in VARCHAR columns", I think it's nice to know why it is:
For the most common COLLATIONs
, like the default ones as Latin1_General_CI_AI
or SQL_Latin1_General_CP1_CI_AS
the ENCODING
will be Windows-1252
for varchar
fields. If we take a look on it's documentation, we can see that it supports:
English, Irish, Italian, Norwegian, Portuguese, Spanish, Swedish. Plus also German, Finnish and French. And Dutch except the ? character
But as I said before, it's not about language, it's about what characters do you expect to support/store, as shown in the emoji example, or some sentence like "The electric resistance of a lithium battery is 0.5O" where we have again plain English, and a Greek letter/character "omega" (which is the symbol for resistance in ohms), which won't be correctly handled by Windows-1252
ENCODING
.
Conclusion:
So, there it is! When use char
/nchar
and varchar
/nvarchar
depends on the characters that you want to support, and also the version of your SQL Server that will determines which COLLATIONs
and hence the ENCODINGs
you have available.
What is UNICODE, ENCODING, COLLATION and UTF-8, and how they are related
Note: all the explanations below are simplifications. Please, refer to the supplied documentation links to know all the details about those concepts.
UNICODE
- Is a standard, a convention, that aims to regulate all the characters in a unified and organized table. In this table, every character has an unique number. This number is commonly called character's code point
.
UNICODE IS NOT AN ENCODING!
ENCODING
- Is a mapping between a character and a byte/bytes sequence. So a encoding is used to "transform" a character to bytes and also the other way around, from bytes to a character. Among the most popular ones are UTF-8
, ISO-8859-1
, Windows-1252
and ASCII
. You can think of it as a "conversion table" (i really simplified here).
COLLATION
- That one is important. Even Microsoft's documentation doesn't let this clear as it should be. A Collation specifies how your data would be sorted, compared, AND STORED!. Yeah, I bet you was not expecting for that last one, right!? The collations on SQL Server
determines too what would be the ENCODING
used on that particular char
/nchar
/varchar
/nvarchar
field.
ASCII ENCODING
- Was one of the firsts encodings. It is both the character table (like an own tiny version of UNICODE
) and its byte mappings. So it doesn't map a byte to UNICODE
, but map a byte to its own character's table. Also, it always use only 7bits, and supported 128 different characters. It was enough to support all English letters upper and down cased, numbers, punctuation and some other limited number of characters. The problem with ASCII is that since it only used 7bits and almost every computer was 8bits at the time, there were another 128 possibilities of characters to be "explored", and everybody started to map this "available" bytes to its own table of characters, creating a lot of different ENCODINGs
.
UTF-8 ENCODING
- This is another ENCODING
, one of the most (if not the most) used ENCODING
around. It uses variable byte width (one character can be from 1 to 6 bytes long, by specification) and fully supports all UNICODE
characters.
Windows-1252 ENCODING
- Also one of the most used ENCODING
, it's widely used on SQL Server. It's fixed-size, so every one character is always 1byte. It also supports a lot of accents, from various languages but doesn't support all existing, nor supports UNICODE
. That's why your varchar
field with a common collation like Latin1_General_CI_AS
supports á
,é
,ñ
characters, even that it isn't using a supportive UNICODE
ENCODING
.

In C++, use no-argument constructors. In C you can't have constructors, so use either memset
or - the interesting solution - designated initializers:
struct Snapshot s = { .x = 0.0, .y = 0.0 };
Did you setup your project to be compiled with 1.4 compliance? If so, do what krock said. Or to be more exact you need to select the J2SE-1.4 execution environment and check one of the installed JRE that you want to use in 1.4 compliance mode; most likely you'll have a 1.6 JRE installed, just check that one. Or install a 1.4 JRE if you have a setup kit, and use that one.
Otherwise go to your Eclipse preferences, Java -> Compiler and check if the compliance is set to 1.4. If it is change it back to 1.6. If it's not go to the project properties, and check if it has project specific settings. Go to Java Compiler, and uncheck that if you want to use the general eclipse preferences. Or set the project specific settings to 1.6, so that it's always 1.6 regardless of eclipse preferences.
From the Package Explorer in Eclipse, you can right click the project, choose Build Path, Configure Build Path to get the build path dialog. From there you can remove the JRE reference for the 1.5 JRE and 'Add Library' to add a reference to your installed JRE.
If you want to replace multiple values in a data frame, looping through all columns might help.
Say you want to replace ""
and 100
:
na_codes <- c(100, "")
for (i in seq_along(df)) {
df[[i]][df[[i]] %in% na_codes] <- NA
}
if you want to remove item you should do this: first remove item:
phones.remove(position);
in next step you should notify your recycler adapter that you remove an item by this code:
notifyItemRemoved(position);
notifyItemRangeChanged(position, phones.size());
but if you change an item do this: first change a parameter of your object like this:
Service s = services.get(position);
s.done = "Cancel service";
services.set(position,s);
or new it like this :
Service s = new Service();
services.set(position,s);
then notify your recycler adapter that you modify an item by this code:
notifyItemChanged(position);
notifyItemRangeChanged(position, services.size());
hope helps you.
I use three flags to resolve the problem:
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
Intent.FLAG_ACTIVITY_CLEAR_TASK |
Intent.FLAG_ACTIVITY_NEW_TASK);
Some JavaScript engines can parse that format directly, which makes the task pretty easy:
function convertDate(inputFormat) {_x000D_
function pad(s) { return (s < 10) ? '0' + s : s; }_x000D_
var d = new Date(inputFormat)_x000D_
return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/')_x000D_
}_x000D_
_x000D_
console.log(convertDate('Mon Nov 19 13:29:40 2012')) // => "19/11/2012"
_x000D_
The std::string::append()
method expects its argument to be a NULL terminated string (char*
).
There are several approaches for producing a string
containg an int
:
#include <sstream>
std::ostringstream s;
s << "select logged from login where id = " << ClientID;
std::string query(s.str());
std::to_string
(C++11)
std::string query("select logged from login where id = " +
std::to_string(ClientID));
#include <boost/lexical_cast.hpp>
std::string query("select logged from login where id = " +
boost::lexical_cast<std::string>(ClientID));
I met the same problem even using -ldl
.
Besides this option, source files need to be placed before libraries, see undefined reference to `dlopen'.
An explicit call to a parent class constructor is required any time the parent class lacks a no-argument constructor. You can either add a no-argument constructor to the parent class or explicitly call the parent class constructor in your child class.
Modulus division gives you the remainder of a division, rather than the quotient.
You should try this syntax - assuming you want to have @OrderID
as a parameter for your stored procedure:
CREATE PROCEDURE dbo.YourStoredProcNameHere
@OrderID INT
AS
BEGIN
DECLARE @OrderItemID AS INT
DECLARE @AppointmentID AS INT
DECLARE @PurchaseOrderID AS INT
DECLARE @PurchaseOrderItemID AS INT
DECLARE @SalesOrderID AS INT
DECLARE @SalesOrderItemID AS INT
SELECT @OrderItemID = OrderItemID
FROM [OrderItem]
WHERE OrderID = @OrderID
SELECT @AppointmentID = AppoinmentID
FROM [Appointment]
WHERE OrderID = @OrderID
SELECT @PurchaseOrderID = PurchaseOrderID
FROM [PurchaseOrder]
WHERE OrderID = @OrderID
END
OF course, that only works if you're returning exactly one value (not multiple values!)
Just stumbled accross this post.
Some time ago I made a suggestion on Visual Studio Connect about adding a new ???
operator.
This would require some work from the framework team but don't need to alter the language but just do some compiler magic. The idea was that the compiler should change this code (syntax not allowed atm)
string product_name = Order.OrderDetails[0].Product.Name ??? "no product defined";
into this code
Func<string> _get_default = () => "no product defined";
string product_name = Order == null
? _get_default.Invoke()
: Order.OrderDetails[0] == null
? _get_default.Invoke()
: Order.OrderDetails[0].Product == null
? _get_default.Invoke()
: Order.OrderDetails[0].Product.Name ?? _get_default.Invoke()
For null check this could look like
bool isNull = (Order.OrderDetails[0].Product ??? null) == null;
ACID properties are very old and important concept of database theory. I know that you can find lots of posts on this topic, but still I would like to start share answer on this because this is very important topic of RDBMS.
Database System plays with lots of different types of transactions where all transaction has certain characteristic. This characteristic is known ACID Properties. ACID Properties take grantee for all database transactions to accomplish all tasks.
Atomicity : Either commit all or nothing.
Consistency : Make consistent record in terms of validate all rule and constraint of transaction.
Isolation : Make sure that two transaction is unaware to each other.
Durability : committed data stored forever. Reference taken from this article:
In case you were wondering where to add @Service
annotation, then
make sure you have added @Service
annotation to the class that implements the interface. That would solve this problem.
For me, none of the other solutions worked (including the clean/rebuild strategy). I found another workaround solution which is to close and re-open Visual Studio.
I guess this forces Visual Studio to re-load the solution and all the projects, rechecking the dependencies in the process.
Use a std::wstring
instead of a C99 variable length array. The current standard guarantees a contiguous buffer for std::basic_string
. E.g.,
std::wstring wc( cSize, L'#' );
mbstowcs( &wc[0], c, cSize );
C++ does not support C99 variable length arrays, and so if you compiled your code as pure C++, it would not even compile.
With that change your function return type should also be std::wstring
.
Remember to set relevant locale in main
.
E.g., setlocale( LC_ALL, "" )
.
Cheers & hth.,
NUMERIC(3,2)
means: 3 digits in total, 2 after the decimal point. So you only have a single decimal before the decimal point.
Try NUMERIC(5,2)
- three before, two after the decimal point.
This is example code that works for sure. It took me a day to make this to read a set of objects from a REST service:
RootObject is the type of the object I'm reading from the REST service.
string url = @"http://restcountries.eu/rest/v1";
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(IEnumerable<RootObject>));
WebClient syncClient = new WebClient();
string content = syncClient.DownloadString(url);
using (MemoryStream memo = new MemoryStream(Encoding.Unicode.GetBytes(content)))
{
IEnumerable<RootObject> countries = (IEnumerable<RootObject>)serializer.ReadObject(memo);
}
Console.Read();
jQuery is just wrapping the standard resize
DOM event, eg.
window.onresize = function(event) {
...
};
jQuery may do some work to ensure that the resize event gets fired consistently in all browsers, but I'm not sure if any of the browsers differ, but I'd encourage you to test in Firefox, Safari, and IE.
How to build iOS project with command?
Clean : codebuild clean -workspace work-space-name.xcworkspace -scheme scheme-name
&&
Archive : xcodebuild archive -workspace work-space-name.xcworkspace -scheme "scheme-name" -configuration Release -archivePath IPA-name.xcarchive
&&
Export : xcodebuild -exportArchive -archivePath IPA-name.xcarchive -exportPath IPA-name.ipa -exportOptionsPlist exportOptions.plist
What is ExportOptions.plist?
ExportOptions.plist is required in Xcode . It lets you to specify some options when you create an ipa file. You can select the options in a friendly UI when you use Xcode to archive your app.
Important: Method for release and development is different in ExportOptions.plist
AppStore :
exportOptions_release ~ method = app-store
Development
exportOptions_dev ~ method = development
Create a configuration file and put your entries there.
SERVER_PORT=10000
THREAD_POOL_COUNT=3
ROOT_DIR=/home/
You can load this file using Properties.load(fileName)
and retrieved values you get(key)
;
just put the variable inside the if condition, if variable has any value it will return true else false.
if (response.photo){ // if you are checking for string use this if(response.photo == "") condition
alert("Has Value");
}
else
{
alert("No Value");
};
This can be done in java 8 using Stream.
import java.util.stream.Stream;
String[] stringList = {"Red", "Orange", "Yellow", "Green", "Blue", "Violet", "Orange", "Blue"};
boolean contains = Stream.of(stringList).anyMatch(x -> x.equals(say.getText());
You should try console_runner gem. This gem makes your pure Ruby code executable from command-line. All you need is to add YARD annotations to your code:
# @runnable This tool can talk to you. Run it when you are lonely.
# Written in Ruby.
class MyClass
def initialize
@hello_msg = 'Hello'
@bye_msg = 'Good Bye'
end
# @runnable Say 'Hello' to you.
# @param [String] name Your name
# @param [Hash] options options
# @option options [Boolean] :second_meet Have you met before?
# @option options [String] :prefix Your custom prefix
def say_hello(name, options = {})
second_meet = nil
second_meet = 'Nice to see you again!' if options['second_meet']
prefix = options['prefix']
message = @hello_msg + ', '
message += "#{prefix} " if prefix
message += "#{name}. "
message += second_meet if second_meet
puts message
end
end
Then run it from console:
$ c_run /projects/example/my_class.rb say_hello -n John --second-meet --prefix Mr.
-> Hello, Mr. John. Nice to see you again!
Your solutions only work if you have unique values in your array
See:
<?php
$trans = array("a" => 1, "b" => 1, "c" => 2);
$trans = array_flip($trans);
print_r($trans);
?>
A better way would be unset with array_search, in a loop if neccessary.
Here is an example that does a union between two completely unrelated tables: the Student and the Products table. It generates an output that is 4 columns:
select
FirstName as Column1,
LastName as Column2,
email as Column3,
null as Column4
from
Student
union
select
ProductName as Column1,
QuantityPerUnit as Column2,
null as Column3,
UnitsInStock as Column4
from
Products

Try this:
[ -z "$STATE" ] && echo "Need to set STATE" && exit 1;
To print nth line using sed with a variable as line number:
a=4
sed -e $a'q:d' file

This modification of a_horse_with_no_name's answer will give you the blocking queries in addition to just the blocked sessions:
SELECT

blocking.pid AS blocking_id,
blocking.query AS blocking_query
FROM pg_stat_activity AS activity
JOIN pg_stat_activity AS blocking ON blocking.pid = ANY(pg_blocking_pids(activity.pid));
If you're using CSVWriter. Check that you don't have the option
.withQuotechar(CSVWriter.NO_QUOTE_CHARACTER)

You need to unicode each element of the list individually
[x.encode('utf-8') for x in tmp]
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
Prefix the call with Module2 (ex. Module2.IDLE
). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.
Params contains the following three groups of parameters:
match '/user/:id'
in routes.rb will set params[:id]params[:controller]
and params[:action]
is always available and contains the current controller and actionI can only imagine of sending a value from the server to the client which is (unchanged) sent back to maintain a kind of a state.
Precisely. In fact, it's still being used for this purpose today because HTTP as we know it today is still, at least fundamentally, a stateless protocol.
This use case was actually first described in HTML 3.2 (I'm surprised HTML 2.0 didn't include such a description):
type=hidden
These fields should not be rendered and provide a means for servers to store state information with a form. This will be passed back to the server when the form is submitted, using the name/value pair defined by the corresponding attributes. This is a work around for the statelessness of HTTP. Another approach is to use HTTP "Cookies".<input type=hidden name=customerid value="c2415-345-8563">
While it's worth mentioning that HTML 3.2 became a W3C Recommendation only after JavaScript's initial release, it's safe to assume that hidden fields have pretty much always served the same purpose.
I much more recommend you to use ES6 with it's perfect Object.assign()
method.
Object.assign({}, ...array.map(([ key, value ]) => ({ [key]: value })));
What happening here - Object.assign()
do nothing but take key:value from donating object and puts pair in your result. In this case I'm using ...
to split new array
to multiply pairs (after map it looks like [{'cardType':'iDEBIT'}, ... ]
). So in the end, new {}
receives every key:property from each pair from mapped array
.
>>> numpy.array([[1, 2], [3, 4]])
array([[1, 2], [3, 4]])
Using latest Asp.Net Identity with .net core 2.1, I'm being able to update user claims with the following logic.
Register a UserClaimsPrincipalFactory
so that every time SignInManager
sings user in, the claims are created.
services.AddScoped<IUserClaimsPrincipalFactory<ApplicationUser>, UserClaimService>();
Implement a custom UserClaimsPrincipalFactory<TUser, TRole>
like below
public class UserClaimService : UserClaimsPrincipalFactory<ApplicationUser, ApplicationRole>
{
private readonly ApplicationDbContext _dbContext;
public UserClaimService(ApplicationDbContext dbContext, UserManager<ApplicationUser> userManager, RoleManager<ApplicationRole> roleManager, IOptions<IdentityOptions> optionsAccessor) : base(userManager, roleManager, optionsAccessor)
{
_dbContext = dbContext;
}
public override async Task<ClaimsPrincipal> CreateAsync(ApplicationUser user)
{
var principal = await base.CreateAsync(user);
// Get user claims from DB using dbContext
// Add claims
((ClaimsIdentity)principal.Identity).AddClaim(new Claim("claimType", "some important claim value"));
return principal;
}
}
Later in your application when you change something in the DB and would like to reflect this to your authenticated and signed in user, following lines achieves this:
var user = await _userManager.GetUserAsync(User);
await _signInManager.RefreshSignInAsync(user);
This makes sure user can see up to date information without requiring login again. I put this just before returning the result in the controller so that when the operation finishes, everything securely refreshed.
Instead of editing existing claims and creating race conditions for secure cookie etc, you just sign user in silently and refresh the state :)
means you have already created a class with same name.
For Example:
class ExampleReDeclare {}
// some code here
class ExampleReDeclare {}
That second ExampleReDeclare throw the error.
make folder and name it foe example download open note pad and insert this code
only change http://www.google.com/aa.zip to your file and save it to m.php for example
chamod the php file to 666 and the folder download to 777
<?php
define('BUFSIZ', 4095);
$url = 'http://www.google.com/aa.zip';
$rfile = fopen($url, 'r');
$lfile = fopen(basename($url), 'w');
while(!feof($rfile))
fwrite($lfile, fread($rfile, BUFSIZ), BUFSIZ);
fclose($rfile);
fclose($lfile);
?>
finally from your browser enter to these URL http://www.example.com/download/m.php
you will see in download folder the file download from other server
thanks
It really depends on the kind of classes as not all classes are created equal.
As general guideline I would suggest 2 options:
Instead of saving it to a file, save it to php://output
Docs:
$objWriter->save('php://output');
This will send it AS-IS to the browser.
You want to add some headersDocs first, like it's common with file downloads, so the browser knows which type that file is and how it should be named (the filename):
// We'll be outputting an excel file
header('Content-type: application/vnd.ms-excel');
// It will be called file.xls
header('Content-Disposition: attachment; filename="file.xls"');
// Write file to the browser
$objWriter->save('php://output');
First do the headers, then the save. For the excel headers see as well the following question: Setting mime type for excel document.
L = ['L','O','L']
makeitastring = ''.join(map(str, L))
This will help you to overcome overflow: overlay
issues as well.
.div{
height: 300px;
overflow: auto;

}
.div-content,
.div:hover {
visibility: visible;
}
To summarize, this is what you should do :
Set path_to_submodule var (no trailing slash):
path_to_submodule=path/to/submodule
Delete the relevant line from the .gitmodules file:
git config -f .gitmodules --remove-section submodule.$path_to_submodule
Delete the relevant section from .git/config
git config -f .git/config --remove-section submodule.$path_to_submodule
Unstage and remove $path_to_submodule only from the index (to prevent losing information)
git rm --cached $path_to_submodule
Track changes made to .gitmodules
git add .gitmodules
Commit the superproject
git commit -m "Remove submodule submodule_name"
Delete the now untracked submodule files
rm -rf $path_to_submodule
rm -rf .git/modules/$path_to_submodule

After trying everything between Stackoverflow and Google, I finally found a solution : http://blogs.lessthandot.com/index.php/datamgmt/dbadmin/remote-procedure-call-failed/
TL;DR :
If you are (or were) running multiple versions of SQL Server on your machine, that Configuration Manager shortcut on your start menu might be pointing to an older version, which it shouldn't be. It was pointing to an old Sql Server 2008 instance in my case.
The solution was to :
Let is a mathematical statement that was adopted by early programming languages like Scheme and Basic. Variables are considered low level entities not suitable for higher levels of abstraction, thus the desire of many language designers to introduce similar but more powerful concepts like in Clojure, F#, Scala, where let
might mean a value, or a variable that can be assigned, but not changed, which in turn lets the compiler catch more programming errors and optimize code better.
JavaScript has had var
from the beginning, so they just needed another keyword, and just borrowed from dozens of other languages that use let
already as a traditional keyword as close to var
as possible, although in JavaScript let
creates block scope local variable instead.

I have found a better way which works on Laravel 5.5 and makes variables accessible by views. And you can retrieve data from the database, do your logic by importing your Model just as you would in your controller.
The "*" means you are referencing all views, if you research more you can choose views to affect.
add in your app/Providers/AppServiceProvider.php
<?php
namespace App\Providers;
use Illuminate\Contracts\View\View;
use Illuminate\Support\ServiceProvider;
use App\Setting;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
// Fetch the Site Settings object
view()->composer('*', function(View $view) {
$site_settings = Setting::all();
$view->with('site_settings', $site_settings);
});
}
/**
* Register any application services.
*
* @return void
*/
public function register()
{
}
}
It works, when you use both lines:
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"
Here's a derived HorizontalScrollView I wrote to handle notifications about scrolling and scroll ending. It properly handles when a user has stopped actively scrolling and when it fully decelerates after a user lets go:
public class ObservableHorizontalScrollView extends HorizontalScrollView {
public interface OnScrollListener {
public void onScrollChanged(ObservableHorizontalScrollView scrollView, int x, int y, int oldX, int oldY);
public void onEndScroll(ObservableHorizontalScrollView scrollView);
}
private boolean mIsScrolling;
private boolean mIsTouching;
private Runnable mScrollingRunnable;
private OnScrollListener mOnScrollListener;
public ObservableHorizontalScrollView(Context context) {
this(context, null, 0);
}
public ObservableHorizontalScrollView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public ObservableHorizontalScrollView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
int action = ev.getAction();
if (action == MotionEvent.ACTION_MOVE) {
mIsTouching = true;
mIsScrolling = true;
} else if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) {
if (mIsTouching && !mIsScrolling) {
if (mOnScrollListener != null) {
mOnScrollListener.onEndScroll(this);
}
}
mIsTouching = false;
}
return super.onTouchEvent(ev);
}
@Override
protected void onScrollChanged(int x, int y, int oldX, int oldY) {
super.onScrollChanged(x, y, oldX, oldY);
if (Math.abs(oldX - x) > 0) {
if (mScrollingRunnable != null) {
removeCallbacks(mScrollingRunnable);
}
mScrollingRunnable = new Runnable() {
public void run() {
if (mIsScrolling && !mIsTouching) {
if (mOnScrollListener != null) {
mOnScrollListener.onEndScroll(ObservableHorizontalScrollView.this);
}
}
mIsScrolling = false;
mScrollingRunnable = null;
}
};
postDelayed(mScrollingRunnable, 200);
}
if (mOnScrollListener != null) {
mOnScrollListener.onScrollChanged(this, x, y, oldX, oldY);
}
}
public OnScrollListener getOnScrollListener() {
return mOnScrollListener;
}
public void setOnScrollListener(OnScrollListener mOnEndScrollListener) {
this.mOnScrollListener = mOnEndScrollListener;
}
}
Not the most elegant solution, and only works 90% of the time:
def vardict(*args):
ns = inspect.stack()[1][0].f_locals
retval = {}
for a in args:
found = False
for k, v in ns.items():
if a is v:
retval[k] = v
if found:
raise ValueError("Value found in more than one local variable: " + str(a))
found = True
if found:
continue
if 'self' in ns:
for k, v in ns['self'].__dict__.items():
if a is v:
retval[k] = v
if found:
raise ValueError("Value found in more than one instance attribute: " + str(a))
found = True
if found:
continue
for k, v in globals().items():
if a is v:
retval[k] = v
if found:
raise ValueError("Value found in more than one global variable: " + str(a))
found = True
assert found, "Couldn't find one of the parameters."
return retval
You'll run into problems if you store the same reference in multiple variables, but also if multiple variables store the same small int, since these get interned.

We don't have option to truncate dynamo tables. we have to drop the table and create again . DynamoDB Charges are based on ReadCapacityUnits & WriteCapacityUnits . If we delete all items using BatchWriteItem function, it will use WriteCapacityUnits.So better to delete specific records or delete the table and start again .
Microsoft .NET framework 3.5 can be installed on windows 10 without having installation media. The file you need is called microsoft-windows-netfx3-ondemand-package.cab
. Just google it and you will get the download links.
After downloading it, copy that file to C:\dotnet35
and run the following command.
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess
Tested and worked in Windows 10 without any issue.
Adding to SimonHawesome's excellent answer. I've made an succinct version which utilizes some of the new typescript features. I realize that SimonHawesome's version is intentionally verbose as to explain the underlying details. I've also added an early-out check so that the pipe works for falsy values. E.g., if the map is null
.
Note that using a iterator transform (as done here) can be more efficient since we do not need to allocate memory for a temporary array (as done in some of the other answers).
import {Pipe, PipeTransform} from '@angular/core';
@Pipe({
name: 'mapToIterable'
})
export class MapToIterable implements PipeTransform {
transform(map: { [key: string]: any }, ...parameters: any[]) {
if (!map)
return undefined;
return Object.keys(map)
.map((key) => ({ 'key': key, 'value': map[key] }));
}
}
python <main module>.py
does not work with relative importThe problem is relative import does not work when you run a __main__
module from the command line
python <main_module>.py
It is clearly stated in PEP 338.
The release of 2.5b1 showed a surprising (although obvious in retrospect) interaction between this PEP and PEP 328 - explicit relative imports don't work from a main module. This is due to the fact that relative imports rely on
__name__
to determine the current module's position in the package hierarchy. In a main module, the value of__name__
is always'__main__'
, so explicit relative imports will always fail (as they only work for a module inside a package).
The issue isn't actually unique to the -m switch. The problem is that relative imports are based on
__name__
, and in the main module,__name__
always has the value__main__
. Hence, relative imports currently can't work properly from the main module of an application, because the main module doesn't know where it really fits in the Python module namespace (this is at least fixable in theory for the main modules executed through the -m switch, but directly executed files and the interactive interpreter are completely out of luck).
To understand further, see Relative imports in Python 3 for the detailed explanation and how to get it over.
If you want to determine whether a key is there in map or not, you can use the find() or count() member function of map. The find function which is used here in example returns the iterator to element or map::end otherwise. In case of count the count returns 1 if found, else it returns zero(or otherwise).
if(phone.count(key))
{ //key found

When you say 2^8
you get 256
, but the numbers in computers terms begins from the number 0
. So, then you got the 255
, you can probe it in a internet mask for the IP or in the IP itself.
255
is the maximum value of a 8 bit integer : 11111111 = 255
Does that help?
If you're using T-SQL
, the only thing wrong with your code is that you used braces {}
instead of parentheses ()
.
PS: Both IDENTITY
and PRIMARY KEY
imply NOT NULL
, so you can omit that if you wish.
You can use a try/catch clause and check to see if it exist:
try
{
if (!Directory.Exists(path))
{
// Try to create the directory.
DirectoryInfo di = Directory.CreateDirectory(path);
}
}
catch (IOException ioex)
{
Console.WriteLine(ioex.Message);
}
You can pass -b option when you compile code via coffee-script under node.js. The compiled code will be the same as on coffeescript.org.
It is useful to think of MIME in the context of the client-server model. Clients and servers communicate over what is known as the HTTP protocol. In a http request or response, we can have a body. The Content-type or MIME type specifies what is the type of the body, like text/javascript
or something else like audio, video, etc.
However, MIME types are not limited just to HTTP.
As the name suggests, MIME stands for Multipurpose Internet Mail Extensions. Originally, SMTP only supported ascii-encodings. However, there as a need for more. We could use MIME to slap a label on the content being transmitted or received.
I actually often use Java style: PascalCase for type names, camelCase for functions and variables, CAPITAL_WORDS for preprocessor macros. I prefer that over the Boost/STL conventions because you don't have to suffix types with _type
. E.g.
Size size();
instead of
size_type size(); // I don't like suffixes
This has the additional benefit that the StackOverflow code formatter recognizes Size
as a type name ;-)
Look here -> https://material-ui.com/guides/composition/#button.
This is the official material-ui guide. Maybe it'll be useful to you as it was for me.
However, in some cases, underline persists and you may want to use text-decoration: "none" for that. For a more cleaner approach, you can import and use makeStyles from material-ui/core.
import { makeStyles } from '@material-ui/core';
const useStyles = makeStyles(() => ({
menu-btn: {
textDecoration: 'none',
},
}));
const classes = useStyles();
And then set className attribute to {classes.menu-btn} in your JSX code.
public string GetCurrentYear()
{
string CurrentYear = DateTime.Now.Year.ToString();
return CurrentYear;
}
public string GetCurrentMonth()
{
string CurrentMonth = DateTime.Now.Month.ToString();
return CurrentMonth;
}
Also, if you don't have the gradlew file in your current directory:
You can install gradle with homebrew with the following command:
$ brew install gradle
As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):
$ gradle test
The answer by Chinmay Kanchi is excellent but I wanted an example of a function which passes and returns a variables/arrays to a C++ code. I though I'd include it here in case it is useful to others.
Passing and returning an integer
The C++ code for a function which takes an integer and adds one to the returned value,
extern "C" int add_one(int i)
{
return i+1;
}
Saved as file test.cpp
, note the required extern "C" (this can be removed for C code).
This is compiled using g++, with arguments similar to Chinmay Kanchi answer,
g++ -shared -o testlib.so -fPIC test.cpp
The Python code uses load_library
from the numpy.ctypeslib
assuming the path to the shared library in the same directory as the Python script,
import numpy.ctypeslib as ctl
import ctypes
libname = 'testlib.so'
libdir = './'
lib=ctl.load_library(libname, libdir)
py_add_one = lib.add_one
py_add_one.argtypes = [ctypes.c_int]
value = 5
results = py_add_one(value)
print(results)
This prints 6 as expected.
Passing and printing an array
You can also pass arrays as follows, for a C code to print the element of an array,
extern "C" void print_array(double* array, int N)
{
for (int i=0; i<N; i++)
cout << i << " " << array[i] << endl;
}
which is compiled as before and the imported in the same way. The extra Python code to use this function would then be,
import numpy as np
py_print_array = lib.print_array
py_print_array.argtypes = [ctl.ndpointer(np.float64,
flags='aligned, c_contiguous'),
ctypes.c_int]
A = np.array([1.4,2.6,3.0], dtype=np.float64)
py_print_array(A, 3)
where we specify the array, the first argument to print_array
, as a pointer to a Numpy array of aligned, c_contiguous 64 bit floats and the second argument as an integer which tells the C code the number of elements in the Numpy array. This then printed by the C code as follows,
1.4
2.6
3.0
Here's something that works in PHP (all PHP intergers are 32 bit signed, thus 31 bit):
function bits_population($nInteger)
{
$nPop=0;
while($nInteger)
{
$nInteger^=(1<<(floor(1+log($nInteger)/log(2))-1));
$nPop++;
}
return $nPop;
}
If you are using ASP.NET Core MVC project. This error message can be shown then you have the correct cshtml
file in your Views
folder but the action is missing in your controller.
Adding the missing action to the controller will fix it.
git pull
is really just a shorthand for git pull <remote> <branchname>
, in most cases it's equivalent to git pull origin master
. You will need to add another remote and pull explicitly from it. This page describes it in detail:
<form id="thisForm" enctype='multipart/form-data'>
<input type="file" name="file" id="file">
</form>
<script>
$(document).on('ready', function(){
$('#file').on('change', function(){
$('#thisForm').submit();
});
});
</script>
use the command-line tool SQLCMD which is much leaner on memory. It is as simple as:
SQLCMD -d <database-name> -i filename.sql
You need valid credentials to access your SQL Server instance or even to access a database
Taken from here.
You can now install an extension View In Browser. I tested it on windows with chrome and it is working.
vscode version: 1.10.2
Change the file name if your file name is like pandas.py or pd.py, it will shadow the real name otherwise.
The above methods seem to be complex. Use my method as a reference.
I have these two files:
run.php
mkdir.py
Here, I've created an HTML page which contains a GO button. Whenever you press this button a new folder will be created in directory whose path you have mentioned.
run.php

Try the array_keys PHP function.
$key_string1 = array_keys($list, 'string1');
I now did the following.
I declared a style inheriting everything from my general style and then disabling the titleBar.
<style name="generalnotitle" parent="general">
<item name="android:windowNoTitle">true</item>
</style>
Now I can set this style to every Activity in which I want to hide the title bar overwriting the application wide style and inheriting all the other style informations, therefor no duplication in the style code.
To apply the style to a particular Activity, open AndroidManifest.xml
and add the following attribute to the activity
tag;
<activity
android:theme="@style/generalnotitle">
My current choice is Razor. It is very clean and easy to read and keeps the view pages very easy to maintain. There is also intellisense support which is really great. ALos, when used with web helpers it is really powerful too.
To provide a simple sample:
@Model namespace.model
<!Doctype html>
<html>
<head>
<title>Test Razor</title>
</head>
<body>
<ul class="mainList">
@foreach(var x in ViewData.model)
{
<li>@x.PropertyName</li>
}
</ul>
</body>
And there you have it. That is very clean and easy to read. Granted, that's a simple example but even on complex pages and forms it is still very easy to read and understand.
As for the cons? Well so far (I'm new to this) when using some of the helpers for forms there is a lack of support for adding a CSS class reference which is a little annoying.
Thanks Nathj07
patrick dw's answer is right on.
For kicks and giggles I thought I would post a simple way to return an array of all the IDs.
var arrayOfIds = $.map($(".myClassName"), function(n, i){
return n.id;
});
alert(arrayOfIds);
Using islice
and chain.from_iterable
:
>>> from itertools import chain, islice
>>> elements = [(1,1,1),(2,3,7),(3,5,10)]
>>> list(chain.from_iterable(islice(item, 1, 2) for item in elements))
[1, 3, 5]
This can be useful when you need more than one element:
>>> elements = [(0, 1, 2, 3, 4, 5),
(10, 11, 12, 13, 14, 15),
(20, 21, 22, 23, 24, 25)]
>>> list(chain.from_iterable(islice(tuple_, 2, 5) for tuple_ in elements))
[2, 3, 4, 12, 13, 14, 22, 23, 24]
The universal tool for string formatting, sprintf
:
$stamp = sprintf('%s%02s', $year, $month);
If you use PreferenceFragment
, this is how I solved it. It's self explanatory.
public static class SettingsFragment extends PreferenceFragment implements OnSharedPreferenceChangeListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
}
@Override
public void onResume() {
super.onResume();
for (int i = 0; i < getPreferenceScreen().getPreferenceCount(); ++i) {
Preference preference = getPreferenceScreen().getPreference(i);
if (preference instanceof PreferenceGroup) {
PreferenceGroup preferenceGroup = (PreferenceGroup) preference;
for (int j = 0; j < preferenceGroup.getPreferenceCount(); ++j) {
Preference singlePref = preferenceGroup.getPreference(j);
updatePreference(singlePref, singlePref.getKey());
}
} else {
updatePreference(preference, preference.getKey());
}
}
}
@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
updatePreference(findPreference(key), key);
}
private void updatePreference(Preference preference, String key) {
if (preference == null) return;
if (preference instanceof ListPreference) {
ListPreference listPreference = (ListPreference) preference;
listPreference.setSummary(listPreference.getEntry());
return;
}
SharedPreferences sharedPrefs = getPreferenceManager().getSharedPreferences();
preference.setSummary(sharedPrefs.getString(key, "Default"));
}
}
They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).
The main equations are:
frame.origin = center - bounds.size / 2
(which is the same as)
center = frame.origin + bounds.size / 2
(and there’s also)
frame.size = bounds.size
That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.
This stuff is all explained in more detail with a useful mini-library here:
You can include the script file directly in your page/master page, etc using:
<script type="text/javascript" src="/scripts/jquery.min.js"></script>
Us use a Content Delivery network like Google or Microsoft:

or:

#region even and odd numbers
for (int x = 0; x <= 50; x = x + 2)
{

y = y + x;
if (y < 50)
{
Console.WriteLine("Odd number is #{" + x + "} : even number is #{" + y + "} order by Asc");
Console.ReadKey();
}
else
{
Console.WriteLine("Odd number is #{" + x + "} : even number is #{0} order by Asc");
Console.ReadKey();
}
}
//order by desc
for (int z = 50; z >= 0; z = z - 2)
{
int w = z;
w = w - 1;
if (w > 0)
{
Console.WriteLine("odd number is {" + z + "} : even number is {" + w + "} order by desc");
Console.ReadKey();
}

{
Console.WriteLine("odd number is {" + z + "} : even number is {0} order by desc");
Console.ReadKey();
}
}
If you want to move an annotated tag, changing only the targeted commit but preserving the annotation message and other metadata use:
moveTag() {
local tagName=$1
# Support passing branch/tag names (not just full commit hashes)
local newTarget=$(git rev-parse $2^{commit})
git cat-file -p refs/tags/$tagName |
sed "1 s/^object .*$/object $newTarget/g" |
git hash-object -w --stdin -t tag |
xargs -I {} git update-ref refs/tags/$tagName {}
}
usage: moveTag <tag-to-move> <target>
The above function was developed by referencing teerapap/git-move-annotated-tag.sh.
If you have a lateinit
property in one class and need to check if it is initialized from another class
if(foo::file.isInitialized) // this wouldn't work
The workaround I have found is to create a function to check if the property is initialized and then you can call that function from any other class.
Example:
class Foo() {
private lateinit var myFile: File
fun isFileInitialised() = ::file.isInitialized
}
// in another class
class Bar() {
val foo = Foo()
if(foo.isFileInitialised()) // this should work
}
You cannot have ref
or out
parameters in async
methods (as was already noted).
This screams for some modelling in the data moving around:
public class Data
{
public int Op {get; set;}
public int Result {get; set;}
}
public async void Method1()
{
Data data = await GetDataTaskAsync();
// use data.Op and data.Result from here on
}
public async Task<Data> GetDataTaskAsync()
{
var returnValue = new Data();
// Fill up returnValue
return returnValue;
}
You gain the ability to reuse your code more easily, plus it's way more readable than variables or tuples.
On gitlab.com a single en space (U+2002) followed by a single em space (U+2003) works decently.
Presumably other repetitions or combinations of not-exactly-accounted-for space characters would also suffice.
I recently run into the same problem. I solved it by implementing my own ImageView class.
Here is my Kotlin implementation:
class MyImageView(context: Context): ImageView(context) {
private var currentDrawableId: Int? = null
override fun setImageResource(resId: Int) {
super.setImageResource(resId)
currentDrawableId = resId
}
fun getDrawableId() {
return currentDrawableId
}
fun compareCurrentDrawable(toDrawableId: Int?): Boolean {
if (toDrawableId == null || currentDrawableId != toDrawableId) {
return false
}
return true
}
}
This is a short way for me to remember it: KOI
NaN
, etc. It uses ===
to distinguish between keys, with one exception NaN !== NaN
but you can use NaN
as a key.[...map]
or [...map.keys()]
has a particular order.obj[key]
or obj.a
(in some language, []
and []=
are really part of the interface). Map has get()
, set()
, has()
, delete()
etc. Note that you can use map[123]
but that is using it as a plain JS object.I just figured this out. My launch image was not showing up, I get a white screen when launching on a device (iPhone 6, 7+) or testFlight. Fix: Renamed "Landing_screen.png" to just "Landing_screen" removing .png part. The image icon in Xcode changed to white icon and in the launch screen storyboard the image appears as a question mark now. The Launch image now appears and not the white screen. My Setup: I am using Swift 3.1 with Xcode 8.3.1. In LaunchScreen.storyboard I added a simple image view and stretched the image to fit the view controller. I set auto layout constraints Top/Bottom/Leading/Trailing space to superview to 0.
This is a very long explanation that I typed up for a coworker of mine. I think it would be helpful here as well. Be patient, though. I get to the real issue that you are having toward the end. Just as a teaser, it's an issue of having extra references to your Line2D
objects hanging around.
WARNING: One other note before we dive in. If you are using IPython to test this out, IPython keeps references of its own and not all of them are weakrefs. So, testing garbage collection in IPython does not work. It just confuses matters.
Okay, here we go. Each matplotlib
object (Figure
, Axes
, etc) provides access to its child artists via various attributes. The following example is getting quite long, but should be illuminating.
We start out by creating a Figure
object, then add an Axes
object to that figure. Note that ax
and fig.axes[0]
are the same object (same id()
).
>>> #Create a figure
>>> fig = plt.figure()
>>> fig.axes
[]
>>> #Add an axes object
>>> ax = fig.add_subplot(1,1,1)
>>> #The object in ax is the same as the object in fig.axes[0], which is
>>> # a list of axes objects attached to fig
>>> print ax
Axes(0.125,0.1;0.775x0.8)
>>> print fig.axes[0]
Axes(0.125,0.1;0.775x0.8) #Same as "print ax"
>>> id(ax), id(fig.axes[0])
(212603664, 212603664) #Same ids => same objects
This also extends to lines in an axes object:
>>> #Add a line to ax
>>> lines = ax.plot(np.arange(1000))
>>> #Lines and ax.lines contain the same line2D instances
>>> print lines
[<matplotlib.lines.Line2D object at 0xce84bd0>]
>>> print ax.lines
[<matplotlib.lines.Line2D object at 0xce84bd0>]
>>> print lines[0]
Line2D(_line0)
>>> print ax.lines[0]
Line2D(_line0)
>>> #Same ID => same object
>>> id(lines[0]), id(ax.lines[0])
(216550352, 216550352)
If you were to call plt.show()
using what was done above, you would see a figure containing a set of axes and a single line:
Now, while we have seen that the contents of lines
and ax.lines
is the same, it is very important to note that the object referenced by the lines
variable is not the same as the object reverenced by ax.lines
as can be seen by the following:
>>> id(lines), id(ax.lines)
(212754584, 211335288)
As a consequence, removing an element from lines
does nothing to the current plot, but removing an element from ax.lines
removes that line from the current plot. So:
>>> #THIS DOES NOTHING:
>>> lines.pop(0)
>>> #THIS REMOVES THE FIRST LINE:
>>> ax.lines.pop(0)
So, if you were to run the second line of code, you would remove the Line2D
object contained in ax.lines[0]
from the current plot and it would be gone. Note that this can also be done via ax.lines.remove()
meaning that you can save a Line2D
instance in a variable, then pass it to ax.lines.remove()
to delete that line, like so:
>>> #Create a new line
>>> lines.append(ax.plot(np.arange(1000)/2.0))
>>> ax.lines
[<matplotlib.lines.Line2D object at 0xce84bd0>, <matplotlib.lines.Line2D object at 0xce84dx3>]
>>> #Remove that new line
>>> ax.lines.remove(lines[0])
>>> ax.lines
[<matplotlib.lines.Line2D object at 0xce84dx3>]
All of the above works for fig.axes
just as well as it works for ax.lines
Now, the real problem here. If we store the reference contained in ax.lines[0]
into a weakref.ref
object, then attempt to delete it, we will notice that it doesn't get garbage collected:
>>> #Create weak reference to Line2D object
>>> from weakref import ref
>>> wr = ref(ax.lines[0])
>>> print wr
<weakref at 0xb758af8; to 'Line2D' at 0xb757fd0>
>>> print wr()
<matplotlib.lines.Line2D at 0xb757fd0>
>>> #Delete the line from the axes
>>> ax.lines.remove(wr())
>>> ax.lines
[]
>>> #Test weakref again
>>> print wr
<weakref at 0xb758af8; to 'Line2D' at 0xb757fd0>
>>> print wr()
<matplotlib.lines.Line2D at 0xb757fd0>
The reference is still live! Why? This is because there is still another reference to the Line2D
object that the reference in wr
points to. Remember how lines
didn't have the same ID as ax.lines
but contained the same elements? Well, that's the problem.
>>> #Print out lines
>>> print lines
[<matplotlib.lines.Line2D object at 0xce84bd0>, <matplotlib.lines.Line2D object at 0xce84dx3>]
To fix this problem, we simply need to delete `lines`, empty it, or let it go out of scope.
>>> #Reinitialize lines to empty list
>>> lines = []
>>> print lines
[]
>>> print wr
<weakref at 0xb758af8; dead>
So, the moral of the story is, clean up after yourself. If you expect something to be garbage collected but it isn't, you are likely leaving a reference hanging out somewhere.
I tested and used this command in kafka confluent V4.0.0
and apache kafka V 1.0.0 and 1.0.1
/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config retention.ms=55000
test
is the topic name.
I think it works well in other versions too
You can't. Security stops you for knowing anything about the filing system of the client computer - it may not even have one! It could be a MAC, a PC, a Tablet or an internet enabled fridge - you don't know, can't know and won't know. And letting you have the full path could give you some information about the client - particularly if it is a network drive for example.
In fact you can get it under particular conditions, but it requires an ActiveX control, and will not work in 99.99% of circumstances.
You can't use it to restore the file to the original location anyway (as you have absolutely no control over where downloads are stored, or even if they are stored) so in practice it is not a lot of use to you anyway.
new
will initialise the default values of the struct and correctly links the references in it to itself.
E.g.
struct test_s {
int some_strange_name = 1;
int &easy = some_strange_name;
}
So new struct test_s
will return an initialised structure with a working reference, while the malloc'ed version has no default values and the intern references aren't initialised.
If you are using Chromium on Ubuntu using the nightly ppa, then you should have the chromium-browser-inspector

I found the solution!
Follow these steps:
After that, execute:
flutter build apk --debug
flutter build apk --profile
flutter build apk --release
and then, run app! it works for me!
If you want it to be List<string>
, get rid of the anonymous type and add a .ToList()
call:
List<string> list = (from char c in source
select c.ToString()).ToList();
You should include the repository where you want to deploy in the distribution management section of the pom.xml
.

I just have to answer here after reading such super-basic advice in the other answers.
For MacOS the default paths are:
When uninstalling remove both directories.
If you've installed manually obviously these directories may be in other places.
One script I came across installed to /usr/local/.go/
a hidden folder because of permissioning... this could trip you up.
In terminal check:
echo $GOPATH
echo $GOROOT
#and
go version
For me after deleting all go folders I was still getting a go version.
Digging through my system path echo $PATH
/Users/bracicot/google-cloud-sdk/bin:/usr/local/bin:
revealed some places to check for still-existing go files such as /usr/local/bin
Another user mentioned:
/etc/paths.d/go
You may also want to remove GOPATH
and GOROOT
environment variables.
Check .zshsrc and or .bash_profile.
Or you can unset GOPATH
and unset GOROOT
You can use the following commands:
To save your uncommitted changes
git stash
To list your saved stashes
git stash list
To apply/get back the uncommited changes where x is 0,1,2...
git stash apply stash@{x}
Note:
To apply a stash and remove it from the stash list
git stash pop stash@{x}
To apply a stash and keep it in the stash list
git stash apply stash@{x}
Maybe grinder will help? You can simulate concurrent request by threads and lightweight processes or distribute test over several machines. I'm using it extensively with success every time.
Probably depending on the XML feed you may/may not need to use __toString()
; I had to use the __toString()
otherwise it is returning the string inside an SimpleXMLElement. Maybe I need to drill down the object further ...

This answer is based on removing and adding views dynamically
To disable scrolling:
View child = scoll.getChildAt(0);// since scrollView can only have one direct child
ViewGroup parent = (ViewGroup) scroll.getParent();
scroll.removeView(child); // remove child from scrollview
parent.addView(child,parent.indexOfChild(scroll));// add scroll child at the position of scrollview
parent.removeView(scroll);// remove scrollView from parent
To enable ScrollView just reverse the process
The answer by shufler is correct. Stated another way: Instead of passing the values to Write-Output using the ARRAY FORM,
Write-Output "Parameters are:" $Year $Month $Day
or the equivalent by multiple calls to Write-Output,
Write-Output "Parameters are:"
Write-Output $Year
Write-Output $Month
Write-Output $Day
Write-Output "Done."
concatenate your components into a STRING VARIABLE first:
$msg="Parameters are: $Year $Month $Day"
Write-Output $msg
This will prevent the intermediate CRLFs caused by calling Write-Output multiple times (or ARRAY FORM), but of course will not suppress the final CRLF of the Write-Output commandlet. For that, you will have to write your own commandlet, use one of the other convoluted workarounds listed here, or wait until Microsoft decides to support the -NoNewline
option for Write-Output.
Your desire to provide a textual progress meter to the console (i.e. "....") as opposed to writing to a log file, should also be satisfied by using Write-Host. You can accomplish both by collecting the msg text into a variable for writing to the log AND using Write-Host to provide progress to the console. This functionality can be combined into your own commandlet for greatest code reuse.
It can also be done using a single line with while
loops and if
like this:
if (blah)
doThis();
It also works with while
loops.
If you are using PHP you might also want to take a look at minify which can minify and combine JavaScript files. The integration is pretty easy and can be done by defined groups of files or an easy query string. Minified files are also cached to reduce the server load and you can add expire headers through minify.
The error is caused by missing jar files. My simple solution is just by copying all the files that does not resolve to the C:\Program Files\Android\Android Studio\gradle\m2repository... (your file path may be different). I got around 6 dependencies that cannot be resolved, junit is one of them and the others are com and org and javax. Since I am behind a firewall, even if I added the code for the repository, the Android Studio doesn't seem to access it. I went to the maven repository and downloaded all the files that will not resolve. Problem solved and the Gradle sync without error. But I am a certified newbie with only 1 day experience so I do not not if this is the proper way to do it.
Example error: Cannot resolve com:squareup:javawriter:2.1.1
Step 1: I created a path C:\Program Files\Android\Android Studio\gradle\m2repository\com\squareup\javawriter\2.1.1\
Step 2: I downloaded all the jar files from the maven repository: http://repo1.maven.org/maven2/com/squareup/javawriter/2.1.1/
Step 3: I manually downloaded all the .jar files from this directory
Step 4: I copied them to C:\Program Files\Android\Android Studio\gradle\m2repository\com\squareup\javawriter\2.1.1\
I repeated this to all the files that did not resolve including the junit.
For junit, here is the directory I created: C:\Program Files\Android\Android Studio\gradle\m2repository\junit\junit\4.12 and then I copied the junit-4.12.jar inside this directory and the junit error disappeared.
You can accomplish this using the function FILL to create filled polygons under the sections of your plots. You will want to plot the lines and polygons in the order you want them to be stacked on the screen, starting with the bottom-most one. Here's an example with some sample data:
x = 1:100; %# X range
y1 = rand(1,100)+1.5; %# One set of data ranging from 1.5 to 2.5
y2 = rand(1,100)+0.5; %# Another set of data ranging from 0.5 to 1.5
baseLine = 0.2; %# Baseline value for filling under the curves
index = 30:70; %# Indices of points to fill under
plot(x,y1,'b'); %# Plot the first line
hold on; %# Add to the plot
h1 = fill(x(index([1 1:end end])),... %# Plot the first filled polygon
[baseLine y1(index) baseLine],...
'b','EdgeColor','none');
plot(x,y2,'g'); %# Plot the second line
h2 = fill(x(index([1 1:end end])),... %# Plot the second filled polygon
[baseLine y2(index) baseLine],...
'g','EdgeColor','none');
plot(x(index),baseLine.*ones(size(index)),'r'); %# Plot the red line
And here's the resulting figure:
You can also change the stacking order of the objects in the figure after you've plotted them by modifying the order of handles in the 'Children'
property of the axes object. For example, this code reverses the stacking order, hiding the green polygon behind the blue polygon:
kids = get(gca,'Children'); %# Get the child object handles
set(gca,'Children',flipud(kids)); %# Set them to the reverse order
Finally, if you don't know exactly what order you want to stack your polygons ahead of time (i.e. either one could be the smaller polygon, which you probably want on top), then you could adjust the 'FaceAlpha'
property so that one or both polygons will appear partially transparent and show the other beneath it. For example, the following will make the green polygon partially transparent:
set(h2,'FaceAlpha',0.5);
In google chrome element.value return the name + the path, but a fake path. Thus, for my case I used the name attribute on the file like below :
function getFileData(myFile){
var file = myFile.files[0];
var filename = file.name;
}
this is the call from the page :
<input id="ph1" name="photo" type="file" class="jq_req" onchange="getFileData(this);"/>
Since Singleton Pattern is about having a private constructor and calling some method to control the instantiations (like some getInstance
), in Enums we already have an implicit private constructor.
I don't exactly know how the JVM or some container controls the instances of our Enums
, but it seems it already use an implicit Singleton Pattern
, the difference is we don't call a getInstance
, we just call the Enum.
I made the following module called unicoder to be able to do the transformation on variables:
import sys
import os
def ustr(string):
string = 'u"%s"'%string
with open('_unicoder.py', 'w') as script:
script.write('# -*- coding: utf-8 -*-\n')
script.write('_ustr = %s'%string)
import _unicoder
value = _unicoder._ustr
del _unicoder
del sys.modules['_unicoder']
os.system('del _unicoder.py')
os.system('del _unicoder.pyc')
return value
Then in your program you could do the following:
# -*- coding: utf-8 -*-
from unicoder import ustr
txt = 'Hello, Unicode World'
txt = ustr(txt)
print type(txt) # <type 'unicode'>
gensim.utils.deaccent(text) from Gensim - topic modelling for humans:
'Sef chomutovskych komunistu dostal postou bily prasek'
Another solution is unidecode.
Note that the suggested solution with unicodedata typically removes accents only in some character (e.g. it turns 'l'
into ''
, rather than into 'l'
).
There is a massive difference in the example you have posted, the first version:
var urls = await context.Urls.ToListAsync();
This is bad, it basically does select * from table
, returns all results into memory and then applies the where
against that in memory collection rather than doing select * from table where...
against the database.
The second method will not actually hit the database until a query is applied to the IQueryable
(probably via a linq .Where().Select()
style operation which will only return the db values which match the query.
If your examples were comparable, the async
version will usually be slightly slower per request as there is more overhead in the state machine which the compiler generates to allow the async
functionality.
However the major difference (and benefit) is that the async
version allows more concurrent requests as it doesn't block the processing thread whilst it is waiting for IO to complete (db query, file access, web request etc).
