With the command:
sudo apt-get remove --purge mysql\*
you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).
You can list all installed mysql packages with the command:
sudo dpkg -l | grep -i mysql
For more cleanup of the package cache, you can use the command:
sudo apt-get clean
Also, remember to use the command:
sudo updatedb
Otherwise the "locate" command will display old data.
To install mysql again, use the following command:
sudo apt-get install libmysqlclient-dev mysql-client
This will install the mysql client, libmysql and its headers files.
To install the mysql server, use the command:
sudo apt-get install mysql-server
Do a (recursive) Revert operation from a level above the directory you deleted.
You should consider not displaying your error messages instead!
Set ini_set('display_errors', 'Off');
in your PHP code (or directly into your ini file if possible), and leave error_reporting on E_ALL
or whatever kind of messages you would like to find in your logs.
This way you can handle errors later, while your users still don't see them.
define('DEBUG', true);
error_reporting(E_ALL);
if (DEBUG)
{
ini_set('display_errors', 'On');
}
else
{
ini_set('display_errors', 'Off');
}
define('DEBUG', true);
error_reporting(E_ALL);
ini_set('display_errors', DEBUG ? 'On' : 'Off');
The history seem to look like this:
Google needs a storage layer for their inverted search index. They figure a traditional RDBMS is not going to cut it. So they implement a NoSQL data store, BigTable on top of their GFS file system. The major part is that thousands of cheap commodity hardware machines provides the speed and the redundancy.
Everyone else realizes what Google just did.
Brewers CAP theorem is proven. All RDBMS systems of use are CA systems. People begin playing with CP and AP systems as well. K/V stores are vastly simpler, so they are the primary vehicle for the research.
Software-as-a-service systems in general do not provide an SQL-like store. Hence, people get more interested in the NoSQL type stores.
I think much of the take-off can be related to this history. Scaling Google took some new ideas at Google and everyone else follows suit because this is the only solution they know to the scaling problem right now. Hence, you are willing to rework everything around the distributed database idea of Google because it is the only way to scale beyond a certain size.
C - Consistency
A - Availability
P - Partition tolerance
K/V - Key/Value
Each call to nextLine()
moves onto the next line, so when you are actually at the last readable line and the while
check passes inspection, the next call to nextLine()
will return EOF
.
Perhaps you could do one of the following instead:
If fileReader
is of type Scanner
:
while ((line = fileReader.hasNextLine()) != null) {
String line = fileReader.nextLine();
System.out.println(line);
}
If fileReader
is of type BufferedReader
:
String line;
while ((line = fileReader.readLine()) != null) {
System.out.println(line);
}
So you're reading the current line in the while condition and saving the line in a string for later use.
If you're using a css library or a theme just apply the classes of a button to the anchor/link tag.
Below is an example with OneUI
<a class="btn-block-option" href="">
<i class="si si-reload"></i>
</a>
The original frameset model (Frameset and Frame-elements) were very bad from a usability standpoint. IFrame vas a later invention which didn't have as many problems as the original frameset model, but it does have its drawback.
If you allow the user to navigate inside the IFrame, then links and bookmarks will not work as expected (because you bookmark the URL of the outer page, but not the URL of the iframe).
Per JamieL's answer to another post:
Since Express.js 3x the response object has a json() method which sets all the headers correctly for you.
Example:
res.json({"foo": "bar"});
This is Windows related issue where SQL Server does not have the appropriate permission to the folder that contains .bak file and hence this error.
The easiest work around is to copy your .bak file to default SQL backup location which has all the necessary permissions. You do not need to fiddle with anything else. In SQL SERVER 2012, this location is
D:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup (SQL 2012)
C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup (SQL 2014)
C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Backup (SQL 2016)

{
string pkgLocation = @"c:\test.dtsx";
Package pkg;
Application app;
DTSExecResult pkgResults;
Variables vars;
app = new Application();

vars = pkg.Variables;
vars["A_Variable"].Value = "Some value";
pkgResults = pkg.Execute(null, vars, null, null, null);
if (pkgResults == DTSExecResult.Success)
Console.WriteLine("Package ran successfully");
else
Console.WriteLine("Package failed");
}
float

If your list of lists contains lists with varying number of elements then the answer of Ignacio Vazquez-Abrams will not work. Instead there are at least 3 options:
1) Make an array of arrays:
x=[[1,2],[1,2,3],[1]]
y=numpy.array([numpy.array(xi) for xi in x])
type(y)
>>><type 'numpy.ndarray'>
type(y[0])
>>><type 'numpy.ndarray'>
2) Make an array of lists:
x=[[1,2],[1,2,3],[1]]
y=numpy.array(x)
type(y)
>>><type 'numpy.ndarray'>
type(y[0])
>>><type 'list'>
3) First make the lists equal in length:
x=[[1,2],[1,2,3],[1]]
length = max(map(len, x))
y=numpy.array([xi+[None]*(length-len(xi)) for xi in x])
y
>>>array([[1, 2, None],
>>> [1, 2, 3],
>>> [1, None, None]], dtype=object)
XAMPP comes preloaded with the FileZilla FTP server. Here is how to setup the service, and create an account.
Enable the FileZilla FTP Service through the XAMPP Control Panel to make it startup automatically (check the checkbox next to filezilla to install the service). Then manually start the service.
Create an ftp account through the FileZilla Server Interface (its the essentially the filezilla control panel). There is a link to it Start Menu in XAMPP folder. Then go to Users->Add User->Stuff->Done.
Try connecting to the server (localhost, port 21).
We can use input data to pass it as a parameter in the HTML file w use ng-model to bind the value of input field.
<input type="text" placeholder="Enter your Email" ng-model="email" required>
<input type="text" placeholder="Enter your password " ng-model="password" required>
and in the js file w use $scope to access this data:
$scope.email="";
$scope.password="";
Controller function will be something like that:
var app = angular.module('myApp', []);
app.controller('assignController', function($scope, $http) {
$scope.email="";
$scope.password="";
$http({
method: "POST",
url: "http://localhost:3000/users/sign_in",
params: {email: $scope.email, password: $scope.password}
}).then(function mySuccess(response) {
// a string, or an object, carrying the response from the server.
$scope.myRes = response.data;
$scope.statuscode = response.status;
}, function myError(response) {
$scope.myRes = response.statusText;
});
});
Go to installed updates and just uninstall Internet Explorer 11 Windows update. It works for me.
You should not be repeating the string
part when sending parameters.
int wordLength = wordLengthFunction(word); //you do not put string word here.
Do what Spectravideo328 answered and:
Try to UNCHECK the iOS 7 and later box and CHECK the iOS 6 and prior box in the asset catalog. There seems to be a bug with the iOS 7 Launch Image. (These both have the same Launch Images except for the 320x480 one)
Hope this helps, it did help for me!
You can configure git to push to the current branch using the following command
git config --global push.default current
then just do
git push
this will push the code to your current branch.
I was using AmplifyJS mentioned below to work around this issue. However, for Safari in Private browsing, it was falling back to a memory-based storage. In my case, it was not appropriate because it means the storage is cleared on refresh, even if the user is still in private browsing.
Also, I have noticed a number of users who are always browsing in Private mode on iOS Safari. For that reason, a better fallback for Safari is to use cookies (if available). By default, cookies are still accessible even in private browsing. Of course, they are cleared when exiting the private browsing, but they are not cleared on refresh.
I found the local-storage-fallback library. From the documentation:
Purpose
With browser settings like "Private Browsing" it has become a problem to rely on a working window.localStorage, even in newer browsers. Even though it may exist, it will throw exceptions when trying to use setItem or getItem. This module will run appropriate checks to see what browser storage mechanism might be available, and then expose it. It uses the same API as localStorage so it should work as a drop-in replacement in most cases.
Beware of the gotchas:
- CookieStorage has storage limits. Be careful here.
- MemoryStorage will not persist between page loads. This is more or less a stop-gap to prevent page crashes, but may be sufficient for websites that don't do full page loads.
Use local-storage-fallback (unified API with .getItem(prop)
and .setItem(prop, val)
):
Check and use appropriate storage adapter for browser (localStorage, sessionStorage, cookies, memory)
To add upon previous answers, one possible workaround would be to change the storage method. There are a few librairies such as AmplifyJS and PersistJS which can help. Both libs allow persistent client-side storage through several backends.
For AmplifyJS
localStorage
- IE 8+
- Firefox 3.5+
- Safari 4+
- Chrome
- Opera 10.5+
- iPhone 2+
- Android 2+
sessionStorage
- IE 8+
- Firefox 2+
- Safari 4+
- Chrome
- Opera 10.5+
- iPhone 2+
- Android 2+
globalStorage
- Firefox 2+
userData
- IE 5 - 7
- userData exists in newer versions of IE as well, but due to quirks in IE 9's implementation, we don't register userData if localStorage is supported.
memory
- An in-memory store is provided as a fallback if none of the other storage types are available.
For PersistentJS
- flash: Flash 8 persistent storage.
- gears: Google Gears-based persistent storage.
- localstorage: HTML5 draft storage.
- globalstorage: HTML5 draft storage (old spec).
- ie: Internet Explorer userdata behaviors.
- cookie: Cookie-based persistent storage.
They offer an abstraction layer so you don't have to worry about choosing the storage type. Keep in mind there might be some limitations (such as size limits) depending on the storage type though. Right now, I am using AmplifyJS, but I still have to do some more testing on iOS 7/Safari/etc. to see if it actually solves the problem.
There are multiple possible causes for this error:
1) When you put the property 'x' inside brackets you are trying to bind to it. Therefore first thing to check is if the property 'x' is defined in your component with an Input()
decorator
Your html file:
<body [x]="...">
Your class file:
export class YourComponentClass {
@Input()
x: string;
...
}
(make sure you also have the parentheses)
2) Make sure you registered your component/directive/pipe classes in NgModule:
@NgModule({
...
declarations: [
...,
YourComponentClass
],
...
})
See https://angular.io/guide/ngmodule#declare-directives for more details about declare directives.
3) Also happens if you have a typo in your angular directive. For example:
<div *ngif="...">
^^^^^
Instead of:
<div *ngIf="...">
This happens because under the hood angular converts the asterisk syntax to:
<div [ngIf]="...">
You should be able to use forward slashes in Java to refer to file locations.
The BufferedReader class is used for wrapping other file readers whos read method may not be very efficient. A more detailed description can be found in the Java APIs.
Toolkit's use of BufferedReader is probably what you need.
Here's a brief one for getting a specified number of tweets from your timeline. It basically does the same thing as the other examples, only with less code.
Just fill in the keys and adjust $count
to your liking:
$url = 'https://api.twitter.com/1.1/statuses/user_timeline.json';
$count = '10';
$oauth = array('count' => $count,
'oauth_consumer_key' => '[CONSUMER KEY]',
'oauth_nonce' => md5(mt_rand()),
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp' => time(),
'oauth_token' => '[ACCESS TOKEN]',
'oauth_version' => '1.0');
$oauth['oauth_signature'] = base64_encode(hash_hmac('sha1', 'GET&' . rawurlencode($url) . '&' . rawurlencode(implode('&', array_map(function ($v, $k) { return $k . '=' . $v; }, $oauth, array_keys($oauth)))), '[CONSUMER SECRET]&[ACCESS TOKEN SECRET]', true));
$twitterData = json_decode(file_get_contents($url . '?count=' . $count, false, stream_context_create(array('http' => array('method' => 'GET',
'header' => 'Authorization: OAuth '
. implode(', ', array_map(function ($v, $k) { return $k . '="' . rawurlencode($v) . '"'; }, $oauth, array_keys($oauth))))))));
This one uses anonymous functions and file_get_contents
instead of the cURL library. Note the use of an MD5 hashed nonce. Everyone seems to be going along with the time()
nonce, however, most examples on the web concerning OAuth use some kind of encrypted string (like this one: http://www.sitepoint.com/understanding-oauth-1/). This makes more sense to me too.
Further note: you need PHP 5.3+ for the anonymous functions (in case your server/computer is in some cold war cave and you can't upgrade it).
The answer provided by polygenelubricants splits an array based on given size. I was looking for code that would split an array into a given number of parts. Here is the modification I did to the code:
public static <T>List<List<T>> chopIntoParts( final List<T> ls, final int iParts )
{
final List<List<T>> lsParts = new ArrayList<List<T>>();
final int iChunkSize = ls.size() / iParts;
int iLeftOver = ls.size() % iParts;
int iTake = iChunkSize;
for( int i = 0, iT = ls.size(); i < iT; i += iTake )
{
if( iLeftOver > 0 )
{
iLeftOver--;
iTake = iChunkSize + 1;
}
else
{
iTake = iChunkSize;
}
lsParts.add( new ArrayList<T>( ls.subList( i, Math.min( iT, i + iTake ) ) ) );
}
return lsParts;
}
Hope it helps someone.
import sys
import time
a = 0
for x in range (0,3):
a = a + 1
b = ("Loading" + "." * a)
# \r prints a carriage return first, so `b` is printed on top of the previous line.
sys.stdout.write('\r'+b)
time.sleep(0.5)
print (a)
Note that you might have to run sys.stdout.flush()
right after sys.stdout.write('\r'+b)
depending on which console you are doing the printing to have the results printed when requested without any buffering.
Try:
adb shell pidof <myPackageName>
Standard output will be empty if the Application is not running. Otherwise, it will output the PID.
oldDate
is not in the format of the SimpleDateFormat
you are using to parse it.
Try this format: dd-MMM-yyyy
- It matches what you're trying to parse.
Workaround:
template<class T, size_t N>
struct simple_array { // like std::array in C++0x
T arr[N];
};
class C : private simple_array<int, 3>
{
static simple_array<int, 3> myarr() {
simple_array<int, 3> arr = {1,2,3};
return arr;
}
public:
C() : simple_array<int, 3>(myarr()) {}
};
Here is some code that might not be optimal but at least actually finds the 2nd largest element:
if( val[ 0 ] > val[ 1 ] )
{
largest = val[ 0 ]
secondLargest = val[ 1 ];
}
else
{
largest = val[ 1 ]
secondLargest = val[ 0 ];
}
for( i = 2; i < N; ++i )
{
if( val[ i ] > secondLargest )
{
if( val[ i ] > largest )
{
secondLargest = largest;
largest = val[ i ];
}
else
{
secondLargest = val[ i ];
}
}
}
It needs at least N-1 comparisons if the largest 2 elements are at the beginning of the array and at most 2N-3 in the worst case (one of the first 2 elements is the smallest in the array).
The error message you are getting is a result of Git still thinking that you have not resolved the merge conflicts. In fact, you already have, but you need to tell Git that you have done this by adding the resolved files to the index.
This has the side effect that you could actually just add the files without resolving the conflicts, and Git would still think that you have. So you should be diligent in making sure that you have really resolved the conflicts. You could even run the build and test the code before you commit.
You may have as many levels of Object hierarchy as you want, as long you declare an Object as being a property of another parent Object. Pay attention to the commas on each level, that's the tricky part. Don't use commas after the last element on each level:
{el1, el2, {el31, el32, el33}, {el41, el42}}

There is very little overall difference between GCC 4.8 and clang 3.3 in terms of speed of the resulting binary. In most cases code generated by both compilers performs similarly. Neither of these two compilers dominates the other one.
Benchmarks telling that there is a significant performance gap between GCC and clang are coincidental.
Program performance is affected by the choice of the compiler. If a developer or a group of developers is exclusively using GCC then the program can be expected to run slightly faster with GCC than with clang, and vice versa.
From developer viewpoint, a notable difference between GCC 4.8+ and clang 3.3 is that GCC has the -Og
command line option. This option enables optimizations that do not interfere with debugging, so for example it is always possible to get accurate stack traces. The absence of this option in clang makes clang harder to use as an optimizing compiler for some developers.

The user Klaro suggested to restore the old visibility classes, which is a good idea. Unfortunately, their solution did not work in my project.
I think that it is a better idea to restore the old mixin of bootstrap, because it is covering all breakpoints which can be individually defined by the user.
Here is the code:
// Restore Bootstrap 3 "hidden" utility classes.
@each $bp in map-keys($grid-breakpoints) {
.hidden-#{$bp}-up {
@include media-breakpoint-up($bp) {
display: none !important;
}
}
.hidden-#{$bp}-down {
@include media-breakpoint-down($bp) {
display: none !important;
}
}
.hidden-#{$bp}-only{
@include media-breakpoint-only($bp){
display:none !important;
}
}
}
In my case, I have inserted this part in a _custom.scss
file which is included at this point in the bootstrap.scss
:

For me, I was receiving this error when connecting to the new IP Address I had configured FileZilla to bind to and saved the configuration. After trying all of the other answers unsuccessfully, I decided to connect to the old IP Address to see what came up; lo and behold it responded.
I restarted the FileZilla Windows Service and it immediately came back listening on the correct IP. Pretty elementary, but it cost me some time today as a noob to FZ.
Hopefully this helps someone out in the same predicament.
Also check if the script has no batch seperator commands (remove the 'GO' statements on a single line).
In Visual Studio, you can't just open a .cpp
file and expect it to run. You must create a project first, or open the .cpp in some existing project.
In your case, there is no project, so there is no project to build.
Go to File --> New --> Project --> Visual C++ --> Win32 Console Application
. You can uncheck "create a directory for solution". On the next page, be sure to check "Empty project".
Then, You can add .cpp
files you created outside the Visual Studio by right clicking in the Solution explorer
on folder icon "Source" and Add->Existing Item.
Obviously You can create new .cpp this way too (Add --> New). The .cpp file will be created in your project directory.
Then you can press ctrl+F5 to compile without debugging and can see output on console window.
All of the solutions are over-engineered.
It is as simple as:
const needle = 5;
const haystack = [1, 2, 3, 4, 5, 6, 7, 8, 9];
haystack.sort((a, b) => {
return Math.abs(a - needle) - Math.abs(b - needle);
})[0];
// 5
Whilst you certainly can use MySQL's IF()
control flow function as demonstrated by dbemerlin's answer, I suspect it might be a little clearer to the reader (i.e. yourself, and any future developers who might pick up your code in the future) to use a CASE
expression instead:
UPDATE Table
SET A = CASE
WHEN A > 0 AND A < 1 THEN 1
WHEN A > 1 AND A < 2 THEN 2
ELSE A
END
WHERE A IS NOT NULL
Of course, in this specific example it's a little wasteful to set A
to itself in the ELSE
clause—better entirely to filter such conditions from the UPDATE
, via the WHERE
clause:
UPDATE Table
SET A = CASE
WHEN A > 0 AND A < 1 THEN 1
WHEN A > 1 AND A < 2 THEN 2
END
WHERE (A > 0 AND A < 1) OR (A > 1 AND A < 2)
(The inequalities entail A IS NOT NULL
).
Or, if you want the intervals to be closed rather than open (note that this would set values of 0
to 1
—if that is undesirable, one could explicitly filter such cases in the WHERE
clause, or else add a higher precedence WHEN
condition):
UPDATE Table
SET A = CASE
WHEN A BETWEEN 0 AND 1 THEN 1
WHEN A BETWEEN 1 AND 2 THEN 2
END
WHERE A BETWEEN 0 AND 2
Though, as dbmerlin also pointed out, for this specific situation you could consider using CEIL()
instead:
UPDATE Table SET A = CEIL(A) WHERE A BETWEEN 0 AND 2
As mentioned before, you cannot create free certificates for S3 buckets. However, you can create Cloud Front distribution and then assign the certificate for the Cloud Front instead. You request the certificate for your domain and then just assign it to the Cloud Front distribution in the Cloud Front settings. I've used this method to serve static websites via SSL as well as serve static files.
For static website creation Amazon is the go to place. It is really affordable to get a static website with SSL.
newaxis
object in the selection tuple serves to expand the dimensions of the resulting selection by one unit-length dimension.
It is not just conversion of row matrix to column matrix.
Consider the example below:
In [1]:x1 = np.arange(1,10).reshape(3,3)
print(x1)
Out[1]: array([[1, 2, 3],
[4, 5, 6],
[7, 8, 9]])
Now lets add new dimension to our data,
In [2]:x1_new = x1[:,np.newaxis]
print(x1_new)
Out[2]:array([[[1, 2, 3]],
[[4, 5, 6]],
[[7, 8, 9]]])
You can see that newaxis
added the extra dimension here, x1 had dimension (3,3) and X1_new has dimension (3,1,3).
How our new dimension enables us to different operations:
In [3]:x2 = np.arange(11,20).reshape(3,3)
print(x2)
Out[3]:array([[11, 12, 13],
[14, 15, 16],
[17, 18, 19]])
Adding x1_new and x2, we get:
In [4]:x1_new+x2
Out[4]:array([[[12, 14, 16],
[15, 17, 19],
[18, 20, 22]],
[[15, 17, 19],
[18, 20, 22],
[21, 23, 25]],
[[18, 20, 22],
[21, 23, 25],
[24, 26, 28]]])
Thus, newaxis
is not just conversion of row to column matrix. It increases the dimension of matrix, thus enabling us to do more operations on it.
For me, I had to add:
git config --global --unset http.proxy
Basically, you can run:
git config --global -l
to get the list of all proxy defined, and then use "--unset" to disable them

There are multiple solution exist but none of them perfect. let's go one by one.
1. Unique Telephony Number (IMEI, MEID, ESN, IMSI)
This solution needs to request for android.permission.READ_PHONE_STATE to your user which can be hard to justify following the type of application you have made.
Furthermore, this solution is limited to smartphones because tablets don’t have telephony services. One advantage is that the value survives to factory resets on devices.
2. MAC Address
3. Serial Number
4. Secure Android ID
On a device first boot, a randomly value is generated and stored. This value is available via Settings.Secure.ANDROID_ID . It’s a 64-bit number that should remain constant for the lifetime of a device. ANDROID_ID seems a good choice for a unique device identifier because it’s available for smartphones and tablets.
String androidId = Settings.Secure.getString(getContentResolver(),Settings.Secure.ANDROID_ID);
However, the value may change if a factory reset is performed on the device. There is also a known bug with a popular handset from a manufacturer where every instance have the same ANDROID_ID. Clearly, the solution is not 100% reliable.
5. Use UUID
As the requirement for most of applications is to identify a particular installation and not a physical device, a good solution to get unique id for an user if to use UUID class. The following solution has been presented by Reto Meier from Google in a Google I/O presentation :
private static String uniqueID = null;
private static final String PREF_UNIQUE_ID = "PREF_UNIQUE_ID";
public synchronized static String id(Context context) {
if (uniqueID == null) {
SharedPreferences sharedPrefs = context.getSharedPreferences(
PREF_UNIQUE_ID, Context.MODE_PRIVATE);
uniqueID = sharedPrefs.getString(PREF_UNIQUE_ID, null);
if (uniqueID == null) {
uniqueID = UUID.randomUUID().toString();
Editor editor = sharedPrefs.edit();
editor.putString(PREF_UNIQUE_ID, uniqueID);
editor.commit();
}
} return uniqueID;
}
Identify a particular device on Android is not an easy thing. There are many good reasons to avoid that. Best solution is probably to identify a particular installation by using UUID solution. credit : blog
Note : This function will ignore the numbers after the decimal mean dot, If you wanna count with decimal then remove the Math.floor()
. Direct to the point check this out!
function digitCount ( num )
{
return Math.floor( num.toString()).length;
}
digitCount(2343) ;
// ES5+
const digitCount2 = num => String( Math.floor( Math.abs(num) ) ).length;
console.log(digitCount2(3343))
Basically What's going on here. toString()
and String()
same build-in function for converting digit to string, once we converted then we'll find the length of the string by build-in function length
.
Alert: But this function wouldn't work properly for negative number, if you're trying to play with negative number then check this answer Or simple put Math.abs()
in it;
Cheer You!
Have you tried using double tabs? To make a box:
Start on a fresh line
Hit tab twice, type up the content
Your content should appear in a box
It works for me in a regular Rmarkdown document with html output. The double-tabbed portion should appear in a rounded rectangular light grey box.
It's simple. I did it the following way to get a string with unique values (from two columns of an output sheet):
Dim startpoint, endpoint, ArrCount As Integer
Dim SentToArr() As String
'created by running the first part (check for new entries)
startpoint = ThisWorkbook.Sheets("temp").Range("A1").Value
'set counter on 0
Arrcount = 0
'last filled row in BG
endpoint = ThisWorkbook.Sheets("BG").Range("G1047854").End(xlUp).Row
'create arr with all data - this could be any data you want!
With ThisWorkbook.Sheets("BG")
For i = startpoint To endpoint
ArrCount = ArrCount + 1
ReDim Preserve SentToArr(1 To ArrCount)
SentToArr(ArrCount) = .Range("A" & i).Value
'get prep
ArrCount = ArrCount + 1
ReDim Preserve SentToArr(1 To ArrCount)
SentToArr(ArrCount) = .Range("B" & i).Value
Next i
End With
'iterate the arr and get a key (l) in each iteration
For l = LBound(SentToArr) To UBound(SentToArr)
Key = SentToArr(l)
'iterate one more time and compare the first key (l) with key (k)
For k = LBound(SentToArr) To UBound(SentToArr)
'if key = the new key from the second iteration and the position is different fill it as empty
If Key = SentToArr(k) And Not k = l Then
SentToArr(k) = ""
End If
Next k
Next l
'iterate through all 'unique-made' values, if the value of the pos is
'empty, skip - you could also create a new array by using the following after the IF below - !! dont forget to reset [ArrCount] as well:
'ArrCount = ArrCount + 1
'ReDim Preserve SentToArr(1 To ArrCount)
'SentToArr(ArrCount) = SentToArr(h)
For h = LBound(SentToArr) To UBound(SentToArr)
If SentToArr(h) = "" Then GoTo skipArrayPart
GetEmailArray = GetEmailArray & "; " & SentToArr(h)
skipArrayPart:
Next h
'some clean up
If Left(GetEmailArray, 2) = "; " Then
GetEmailArray = Right(GetEmailArray, Len(GetEmailArray) - 2)
End If
'show us the money
MsgBox GetEmailArray
If you already know the item is a String
, I prefer:
String itemText = (String) mySpinner.getSelectedItem();
Calling toString()
on an Object
that you know is a String
seems like a more roundabout path than just casting the Object
to String
.
This method is only for those who know that Mysql is installed but still mysql_config can't be find. This happens if python install can't find mysql_config in your system path, which mostly happens if you have done the installation via .dmg Mac Package or installed at some custom path. The easiest and documented way by MySqlDB is to change the site.cfg. Find the mysql_config which is probably in /usr/local/mysql/bin/ and change the variable namely mysql_config just like below and run the installation again. Don't forget to un-comment it by removing "#"
Change below line
"#mysql_config = /usr/local/bin/mysql_config"
to
"mysql_config = /usr/local/mysql/bin/mysql_config"
depending upon the path in your system.
By the way I used python install after changing the site.cfg
sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python setup.py install
I too was looking for a good way to do this, I found the best way was to set a transition on the "transform" property and then change the transform and then remove the transition.
I put it all together in a jQuery plugin
https://gist.github.com/dustinpoissant/8a4837c476e3939a5b3d1a2585e8d1b0
You would use the code like this:
$("#myElement").animateTransform("rotate(180deg)", 750, function(){
console.log("animation completed after 750ms");
});
There is both window.onbeforeunload
and window.onunload
, which are used differently depending on the browser. You can assign them either by setting the window properties to functions, or using the .addEventListener
:
window.onbeforeunload = function(){
// Do something
}
// OR
window.addEventListener("beforeunload", function(e){
// Do something
}, false);
Usually, onbeforeunload
is used if you need to stop the user from leaving the page (ex. the user is working on some unsaved data, so he/she should save before leaving). onunload
isn't supported by Opera, as far as I know, but you could always set both.
I think you are searching for something like this one.
class test {
private $str = NULL;
public function newTest(){
$this->str .= 'function "newTest" called, ';
return $this;
}
public function bigTest(){
return $this->str . ' function "bigTest" called,';
}
public function smallTest(){
return $this->str . ' function "smallTest" called,';
}
public function scoreTest(){
return $this->str . ' function "scoreTest" called,';
}
}
$test = new test;
echo $test->newTest()->bigTest();
If you are using Sql Server Management Studio, you can create your own schema by browsing to Databases - Your Database - Security - Schemas.
To create one using a script is as easy as (for example):
CREATE SCHEMA [EnterSchemaNameHere] AUTHORIZATION [dbo]
You can use them to logically group your tables, for example by creating a schema for "Financial" information and another for "Personal" data. Your tables would then display as:
Financial.BankAccounts Financial.Transactions Personal.Address
Rather than using the default schema of dbo.
In First activity:
ArrayList<ContactBean> fileList = new ArrayList<ContactBean>();
Intent intent = new Intent(MainActivity.this, secondActivity.class);
intent.putExtra("FILES_TO_SEND", fileList);
startActivity(intent);
In receiver activity:
ArrayList<ContactBean> filelist = (ArrayList<ContactBean>)getIntent().getSerializableExtra("FILES_TO_SEND");`
All modern browsers come with some form of a built-in JavaScript debugging application. The details of these will be covered on the relevant technologies web pages. My personal preference for debugging JavaScript is Firebug in Firefox. I'm not saying Firebug is better than any other; it depends on your personal preference and you should probably test your site in all browsers anyway (my personal first choice is always Firebug).
I'll cover some of the high-level solutions below, using Firebug as an example:
Firefox comes with with its own inbuilt JavaScript debugging tool, but I would recommend you install the Firebug add on. This provides several additional features based on the basic version that are handy. I'm going to only talk about Firebug here.
Once Firebug is installed you can access it like below:
Firstly if you right click on any element you can Inspect Element with Firebug:
Clicking this will open up the Firebug pane at the bottom of the browser:
Firebug provides several features but the one we're interested in is the script tab. Clicking the script tab opens this window:
Obviously, to debug you need to click reload:
You can now add breakpoints by clicking the line to the left of the piece of JavaScript code you want to add the breakpoint to:
When your breakpoint is hit, it will look like below:
You can also add watch variables and generally do everything that you would expect in a modern debugging tool.
For more information on the various options offered in Firebug, check out the Firebug FAQ.
Chrome also has its own in built JavaScript debugging option, which works in a very similar way, right click, inspect element, etc.. Have a look at Chrome Developer Tools. I generally find the stack traces in Chrome better than Firebug.
If you're developing in .NET and using Visual Studio using the web development environment you can debug JavaScript code directly by placing breakpoints, etc. Your JavaScript code looks exactly the same as if you were debugging your C# or VB.NET code.
If you don't have this, Internet Explorer also provides all of the tools shown above. Annoyingly, instead of having the right click inspect element features of Chrome or Firefox, you access the developer tools by pressing F12. This question covers most of the points.
I think your best bet is to call GetOrdinal("columnName") on your DataReader up front, and catch an IndexOutOfRangeException in case the column isn't present.
In fact, let's make an extension method:
public static bool HasColumn(this IDataRecord r, string columnName)
{
try
{
return r.GetOrdinal(columnName) >= 0;
}
catch (IndexOutOfRangeException)
{
return false;
}
}
Edit
Ok, this post is starting to garner a few down-votes lately, and I can't delete it because it's the accepted answer, so I'm going to update it and (I hope) try to justify the use of exception handling as control flow.
The other way of achieving this, as posted by Chad Grant, is to loop through each field in the DataReader and do a case-insensitive comparison for the field name you're looking for. This will work really well, and truthfully will probably perform better than my method above. Certainly I would never use the method above inside a loop where performace was an issue.
I can think of one situation in which the try/GetOrdinal/catch method will work where the loop doesn't. It is, however, a completely hypothetical situation right now so it's a very flimsy justification. Regardless, bear with me and see what you think.
Imagine a database that allowed you to "alias" columns within a table. Imagine that I could define a table with a column called "EmployeeName" but also give it an alias of "EmpName", and doing a select for either name would return the data in that column. With me so far?
Now imagine that there's an ADO.NET provider for that database, and they've coded up an IDataReader implementation for it which takes column aliases into account.
Now, dr.GetName(i)
(as used in Chad's answer) can only return a single string, so it has to return only one of the "aliases" on a column. However, GetOrdinal("EmpName")
could use the internal implementation of this provider's fields to check each column's alias for the name you're looking for.
In this hypothetical "aliased columns" situation, the try/GetOrdinal/catch method would be the only way to be sure that you're checking for every variation of a column's name in the resultset.
Flimsy? Sure. But worth a thought. Honestly I'd much rather an "official" HasColumn method on IDataRecord.
OBJECT vs. EMBED - why not always use embed?
Bottom line: OBJECT is Good, EMBED is Old. Beside's IE's PARAM tags, any content between OBJECT tags will get rendered if the browser doesn't support OBJECT's referred plugin, and apparently, the content gets http requested regardless if it gets rendered or not.
object
is the current standard tag to embed something on a page. embed
was included by Netscape (along img
) before anything like object
were on the w3c mind.
This is how you include a PDF with object
:
<object data="data/test.pdf" type="application/pdf" width="300" height="200">
alt : <a href="data/test.pdf">test.pdf</a>
</object>
If you really need the inline PDF to show in almost every browser, as older browsers understand embed
but not object
, you'll need to do this:
<object data="abc.pdf" type="application/pdf">
<embed src="abc.pdf" type="application/pdf" />
</object>
This version does not validate.
This should work:
echo basename($_SERVER['REQUEST_URI'], '?' . $_SERVER['QUERY_STRING']);
But beware of any malicious parts in your URL.

gflags
utility to turn on user-mode stack traces.UMDH
to take multiple snapshots of your program's memory. Take a snapshot before memory gets allocated, and take a second snapshot after a point at which you believe that your program has leaked memory. You might want to add pauses or prompts in your program to give you a chance to run UMDH
and take the snapshots.UMDH
again, this time in its mode that does a diff between the two snapshots. It will then generate a report containing the call stacks of suspected memory leaks.gflags
settings when you're done.UMDH
will give you more information than the CRT debug heap because it is watching memory allocations across your entire process; it can even tell you if third-party components are leaking.
To take first 5 elements better use expression like this one:
var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5);
or
var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5).OrderBy([ORDER EXPR]);
It will be faster than orderBy variant, because LINQ engine will not scan trough all list due to delayed execution, and will not sort all array.
class MyList : IEnumerable<int>
{
int maxCount = 0;
public int RequestCount
{
get;
private set;
}
public MyList(int maxCount)
{
this.maxCount = maxCount;
}
public void Reset()
{
RequestCount = 0;
}
#region IEnumerable<int> Members
public IEnumerator<int> GetEnumerator()
{
int i = 0;
while (i < maxCount)
{
RequestCount++;
yield return i++;
}
}
#endregion
#region IEnumerable Members
System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
{
throw new NotImplementedException();
}
#endregion
}
class Program
{
static void Main(string[] args)
{
var list = new MyList(15);
list.Take(5).ToArray();
Console.WriteLine(list.RequestCount); // 5;
list.Reset();
list.OrderBy(q => q).Take(5).ToArray();
Console.WriteLine(list.RequestCount); // 15;
list.Reset();
list.Where(q => (q & 1) == 0).Take(5).ToArray();
Console.WriteLine(list.RequestCount); // 9; (first 5 odd)
list.Reset();
list.Where(q => (q & 1) == 0).Take(5).OrderBy(q => q).ToArray();
Console.WriteLine(list.RequestCount); // 9; (first 5 odd)
}
}
Don't confuse, if you won't give any strWindowFeatures then it will open in a new tab.
window.open('https://play.google.com/store/apps/details?id=com.drishya');
One big and great approach is to load the module from a NgModuleFactory
, you can load a module inside another module by calling this:
constructor(private loader: NgModuleFactoryLoader, private injector: Injector) {}
loadModule(path: string) {
this.loader.load(path).then((moduleFactory: NgModuleFactory<any>) => {
const entryComponent = (<any>moduleFactory.moduleType).entry;
const moduleRef = moduleFactory.create(this.injector);
const compFactory = moduleRef.componentFactoryResolver.resolveComponentFactory(entryComponent);
this.lazyOutlet.createComponent(compFactory);
});
}
I got this from here.
You're missing a GROUP BY clause:
SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id
The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.
In order to load local images to your React.js application, you need to add require
parameter in media sections like or Image tags, as below:
image={require('./../uploads/temp.jpg')}
You can use:
cat f.csv | sed 's/,/ /g' | awk '{print $1 " / " $4}'
or
echo "Hello,World,Questions,Answers,bash shell,script" | sed 's/,/ /g' | awk '{print $1 " / " $4}'
This is the part that replace comma with space
sed 's/,/ /g'
A shorter solution using data.table
:
setDT(group)[, .SD[which.max(pt)], by=Subject]
# Subject pt Event
# 1: 1 5 2
# 2: 2 17 2
# 3: 3 5 2
Are you searching for this:
int c = some_ascii_character;
Or just converting without assignment:
(int)some_aschii_character;
Quick, interactive way to see column names
If you're working interactively in Python and just want to quickly 'see' the column names, I found cursor.description to work.
import sqlite3
conn = sqlite3.connect('test-db.db')
cursor = conn.execute('select * from mytable')
cursor.description
Outputs something like this:
(('Date', None, None, None, None, None, None),
('Object-Name', None, None, None, None, None, None),
('Object-Count', None, None, None, None, None, None))
Or, quick way to access and print them out.
colnames = cursor.description
for row in colnames:
print row[0]
Outputs something like this:
Date
Object-Name
Object-Count
It must be synchronized, using an object lock, stateless, or immutable.

Deprecated answer (Spring Data JPA <=1.6.x):
@Modifying
annotation to the rescue. You will need to provide your custom SQL behaviour though.
public interface UserRepository extends JpaRepository<User, Long> {
@Modifying
@Query("delete from User u where u.firstName = ?1")
void deleteUsersByFirstName(String firstName);
}
Update:
In modern versions of Spring Data JPA (>=1.7.x) query derivation for delete
, remove
and count
operations is accessible.
public interface UserRepository extends CrudRepository<User, Long> {
Long countByFirstName(String firstName);
Long deleteByFirstName(String firstName);
List<User> removeByFirstName(String firstName);
}
With coming in of Java NIO, below is a possible solution too
With Java 9:
private static void copyDir(String src, String dest, boolean overwrite) {
try {
Files.walk(Paths.get(src)).forEach(a -> {
Path b = Paths.get(dest, a.toString().substring(src.length()));
try {
if (!a.toString().equals(src))
Files.copy(a, b, overwrite ? new CopyOption[]{StandardCopyOption.REPLACE_EXISTING} : new CopyOption[]{});
} catch (IOException e) {
e.printStackTrace();
}
});
} catch (IOException e) {
//permission issue
e.printStackTrace();
}
}
With Java 7:
import java.io.IOException;
import java.nio.file.FileAlreadyExistsException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.function.Consumer;
import java.util.stream.Stream;
public class Test {
public static void main(String[] args) {
Path sourceParentFolder = Paths.get("/sourceParent");
Path destinationParentFolder = Paths.get("/destination/");
try {
Stream<Path> allFilesPathStream = Files.walk(sourceParentFolder);
Consumer<? super Path> action = new Consumer<Path>(){
@Override
public void accept(Path t) {
try {
String destinationPath = t.toString().replaceAll(sourceParentFolder.toString(), destinationParentFolder.toString());
Files.copy(t, Paths.get(destinationPath));
}
catch(FileAlreadyExistsException e){
//TODO do acc to business needs
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
allFilesPathStream.forEach(action );
} catch(FileAlreadyExistsException e) {
//file already exists and unable to copy
} catch (IOException e) {
//permission issue

except for codecs.open()
, one can uses io.open()
to work with Python2 or Python3 to read / write unicode file
example
import io
text = u'á'
encoding = 'utf8'
with io.open('data.txt', 'w', encoding=encoding, newline='\n') as fout:
fout.write(text)
with io.open('data.txt', 'r', encoding=encoding, newline='\n') as fin:
text2 = fin.read()
assert text == text2
also it happens when you import following library to api.php file. this happens by some IDE's suggestion to import it for not finding the Route Class.
just remove it and everything going to work fine.
use Illuminate\Routing\Route;
update:
seems if you add this library it wont lead to error
use Illuminate\Support\Facades\Route;
The best version of this I've found on Windows is Joseph Newcomer's "whereis" utility, which is available (with source) from his site.
The article about the development of "whereis" is worth reading.
Start off by opening a cmd.exe session, changing directory to the "program files" directory that has the javac.exe executable and running .\javac.exe.
If that doesn't work, reinstall java. If that works, odds are you will find (in doing that task) that you've installed a 64 bit javac.exe
, or a slightly different release number of javac.exe
, or in a different drive, etc. and selecting the right entry in your path will become child's play.
Only use the semicolon between directories in the PATH environment variable, and remember that in some systems, you need to log out and log back in before the new environment variable is accessible to all environments.
There is no built in function with this capability. The close would be to save the file in a folder named for the current date and use the =INFO("directory") function.
One of the easiest way is to use a common table expression (since you're already on SQL 2005):
with cte as (
select
im.itemid
,im.sku as iSku
,gm.SKU as GSKU
,mm.ManufacturerId as ManuId
,mm.ManufacturerName
,im.mf_item_number
,mm.ManufacturerID
, <your other field>
from
item_master im, group_master gm, Manufacturer_Master mm
where
im.mf_item_number like 'STA%'
and im.sku=gm.sku
and gm.ManufacturerID = mm.ManufacturerID
and gm.manufacturerID=34)
update cte set mf_item_number = <your other field>
The query execution engine will figure out on its own how to update the record.
Here's one explanation:
Once a socket is no longer required, the calling program can discard the socket by applying a close subroutine to the socket descriptor. If a reliable delivery socket has data associated with it when a close takes place, the system continues to attempt data transfer. However, if the data is still undelivered, the system discards the data. Should the application program have no use for any pending data, it can use the shutdown subroutine on the socket prior to closing it.
Integrating OpenCV v3.1.0 into Android Studio v1.4.1, instructions with additional detail and this-is-what-you-should-get type screenshots.
Most of the credit goes to Kiran, Kool, 1", and SteveLiles over at opencv.org for their explanations. I'm adding this answer because I believe that Android Studio's interface is now stable enough to work with on this type of integration stuff. Also I have to write these instructions anyway for our project.
Experienced A.S. developers will find some of this pedantic. This answer is targeted at people with limited experience in Android Studio.
Create a new Android Studio project using the project wizard (Menu:/File/New Project):
Blank Activity named MainActivity
You should have a cvtest1 directory where this project is stored. (the title bar of Android studio shows you where cvtest1 is when you open the project)
Verify that your app runs correctly. Try changing something like the "Hello World" text to confirm that the build/test cycle is OK for you. (I'm testing with an emulator of an API 19 device).
Download the OpenCV package for Android v3.1.0 and unzip it in some temporary directory somewhere. (Make sure it is the package specifically for Android and not just the OpenCV for Java package.) I'll call this directory "unzip-dir" Below unzip-dir you should have a sdk/native/libs directory with subdirectories that start with things like arm..., mips... and x86... (one for each type of "architecture" Android runs on)
From Android Studio import OpenCV into your project as a module: Menu:/File/New/Import_Module:
Click on next. You get a screen with three checkboxes and questions about jars, libraries and import options. All three should be checked. Click on Finish.
Android Studio starts to import the module and you are shown an import-summary.txt file that has a list of what was not imported (mostly javadoc files) and other pieces of information.
But you also get an error message saying failed to find target with hash string 'android-14'.... This happens because the build.gradle file in the OpenCV zip file you downloaded says to compile using android API version 14, which by default you don't have with Android Studio v1.4.1.
Open the project structure dialogue (Menu:/File/Project_Structure). Select the "app" module, click on the Dependencies tab and add :openCVLibrary310 as a Module Dependency. When you select Add/Module_Dependency it should appear in the list of modules you can add. It will now show up as a dependency but you will get a few more cannot-find-android-14 errors in the event log.
Look in the build.gradle file for your app module. There are multiple build.gradle files in an Android project. The one you want is in the cvtest1/app directory and from the project view it looks like build.gradle (Module: app). Note the values of these four fields:
Your project now has a cvtest1/OpenCVLibrary310 directory but it is not visible from the project view:
Use some other tool, such as any file manager, and go to this directory. You can also switch the project view from Android to Project Files and you can find this directory as shown in this screenshot:
Inside there is another build.gradle file (it's highlighted in the above screenshot). Update this file with the four values from step 6.
Resynch your project and then clean/rebuild it. (Menu:/Build/Clean_Project) It should clean and build without errors and you should see many references to :openCVLibrary310 in the 0:Messages screen.
At this point the module should appear in the project hierarchy as openCVLibrary310, just like app. (Note that in that little drop-down menu I switched back from Project View to Android View ). You should also see an additional build.gradle file under "Gradle Scripts" but I find the Android Studio interface a little bit glitchy and sometimes it does not do this right away. So try resynching, cleaning, even restarting Android Studio.
You should see the openCVLibrary310 module with all the OpenCV functions under java like in this screenshot:
Copy the {unzip-dir}/sdk/native/libs directory (and everything under it) to your Android project, to cvtest1/OpenCVLibrary310/src/main/, and then rename your copy from libs to jniLibs. You should now have a cvtest1/OpenCVLibrary310/src/main/jniLibs directory. Resynch your project and this directory should now appear in the project view under openCVLibrary310.
Go to the onCreate method of MainActivity.java and append this code:
if (!OpenCVLoader.initDebug()) {
Log.e(this.getClass().getSimpleName(), " OpenCVLoader.initDebug(), not working.");
} else {
Log.d(this.getClass().getSimpleName(), " OpenCVLoader.initDebug(), working.");
}
Then run your application. You should see lines like this in the Android Monitor: (I don't know why that line with the error message is there)
Now try to actually use some openCV code. In the example below I copied a .jpg file to the cache directory of the cvtest1 application on the android emulator. The code below loads this image, runs the canny edge detection algorithm and then writes the results back to a .png file in the same directory.
Put this code just below the code from the previous step and alter it to match your own files/directories.
String inputFileName="simm_01";
String inputExtension = "jpg";
String inputDir = getCacheDir().getAbsolutePath(); // use the cache directory for i/o
String outputDir = getCacheDir().getAbsolutePath();
String outputExtension = "png";
String inputFilePath = inputDir + File.separator + inputFileName + "." + inputExtension;
Log.d (this.getClass().getSimpleName(), "loading " + inputFilePath + "...");
Mat image = Imgcodecs.imread(inputFilePath);
Log.d (this.getClass().getSimpleName(), "width of " + inputFileName + ": " + image.width());
// if width is 0 then it did not read your image.
// for the canny edge detection algorithm, play with these to see different results
int threshold1 = 70;
int threshold2 = 100;
Mat im_canny = new Mat(); // you have to initialize output image before giving it to the Canny method
Imgproc.Canny(image, im_canny, threshold1, threshold2);
String cannyFilename = outputDir + File.separator + inputFileName + "_canny-" + threshold1 + "-" + threshold2 + "." + outputExtension;
Log.d (this.getClass().getSimpleName(), "Writing " + cannyFilename);
Imgcodecs.imwrite(cannyFilename, im_canny);
Run your application. Your emulator should create a black and white "edge" image. You can use the Android Device Monitor to retrieve the output or write an activity to show it.
The Gotchas:
You can do it with Alacon - command-line utility for Alasql database. It works with Node.js, so you need to install Node.js and then Alasql package.
To convert Excel file to CVS (ot TSV) you can enter:
> node alacon "SELECT * INTO CSV('mydata.csv', {headers:true}) FROM XLS('mydata.xls', {headers:true})"
By default Alasql converts data from "Sheet1", but you can change it with parameters:
{headers:false, sheetid: 'Sheet2', range: 'A1:C100'}
Alacon supports other type of conversions (CSV, TSV, TXT, XLSX, XLS) and SQL language constructions (see User Manual for examples).
its really simple you can try this:
$("#image id").click(function(){
$("#input id").click();
});
A concise one line:
import java.io.PrintWriter
new PrintWriter("filename") { write("file contents"); close }
We Announce the AryaBootstrap,
The last version is based on bootstrap 4.3.1
AryaBootstrap is a bootstrap with dual layout align support and, used for LTR and RTL web design.
add "dir" to html, thats the only action you need to do.

This is the correct way to change btn color.
.btn-primary:not(:disabled):not(.disabled).active,
.btn-primary:not(:disabled):not(.disabled):active,
.show>.btn-primary.dropdown-toggle{
color: #fff;
background-color: #F7B432;
border-color: #F7B432;
}
If you are using Action, Actionforward way to process business logic and next page to show, check out if redirect is called. As many others pointed out, redirecting doesn't keep your original request since it is basically forcing you to make a new request to designated path. So the value set in original request will be vanished if you use redirection instead of requestdispatch.
The builtin json
module got included in Python 2.6. Any projects that support versions of Python < 2.6 need to have a fallback. In many cases, that fallback is simplejson
.
std::list<Object> l;
std::list<Object>::iterator ptr;
int i;
for( i = 0 , ptr = l.begin() ; i < N && ptr != l.end() ; i++ , ptr++ );
if( ptr == l.end() ) {
// list too short
} else {
// 'ptr' points to N-th element of list
}
What about this solution? Modules and Controllers in Files (at the end of the page) It works with multiple controllers, directives and so on:
app.js
var app = angular.module("myApp", ['deps']);
myCtrl.js
app.controller("myCtrl", function($scope) { ..});
html
<script src="app.js"></script>
<script src="myCtrl.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
Google has also a Best Practice Recommendations for Angular App Structure I really like to group by context. Not all the html in one folder, but for example all files for login (html, css, app.js,controller.js and so on). So if I work on a module, all the directives are easier to find.
for me it was the antivirus. Just add visual studio project or entire parent folder to Antivirus exclusion list or you can also add file extension as exclusion and this method worked for me in visual studio 2010/2012
Before abc was introduced you would see this frequently.
class Base(object):
def go(self):
raise NotImplementedError("Please Implement this method")
class Specialized(Base):
def go(self):
print "Consider me implemented"
Getting the correct line (example for line no. 6) is done with head and tail and the correct word (word no. 4) can be captured with awk:
command|head -n 6|tail -n 1|awk '{print $4}'
if(success == true)
{
//For wait 5 seconds
setTimeout(function()
{
location.reload(); //Refresh page
}, 5000);
}
I have modified the above answer, so you don't need to cast from Object
public static <T> List<T> safeClient( List<T> other ) {
return other == null ? Collections.EMPTY_LIST : other;
}
and then simply call the List by
for (MyOwnObject ownObject : safeClient(someList)) {
// do whatever
}
Explaination:
MyOwnObject: If List<Integer>
then MyOwnObject will be Integer in this case.
I also experienced that for example:
This code doesnt work and get the intended block error.
class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()
def __unicode__(self):
return self.title
However, when i press tab before typing return self.title statement, the code works.
class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()
def __unicode__(self):
return self.title
Hope, this will help others.
adding log4j-1.2.12.jar file has resolved the issue for me
If you have a pristine repo (or HEAD isn't set)[1] you could simply
rm .git/index
Of course, this will require you to re-add the files that you did want to be added.
[1] Note (as explained in the comments) this would usually only happen when the repo is brand-new ("pristine") or if no commits have been made. More technically, whenever there is no checkout or work-tree.
Just making it more clear :)
Another option may be this John Resig remove method. can better fit what you need. if you know the index in the array.
my best solution to get the first is
df['my_column'].value_counts().sort_values(ascending=False).argmax()
Try \n\n , it will work! :)
public async Task AjudaAsync(IDialogContext context, LuisResult result){
await context.PostAsync("How can I help you? \n\n 1.To Schedule \n\n 2.Consult");
context.Wait(MessageReceived);
}
Actually you can set some properties of a view's layer through interface builder. I know that I can set a layer's borderWidth and cornerRadius through xcode. borderColor doesn't work, probably because the layer wants a CGColor instead of a UIColor.
You might have to use Strings instead of numbers, but it works!
layer.cornerRadius
layer.borderWidth
layer.borderColor
Update: layer.masksToBounds = true
Was playing with this today... I beleive you can also use @@ROWCOUNT, like this:
DECLARE @SQL VARCHAR(50)
DECLARE @Rowcount INT
SET @SQL = 'SELECT 1 UNION SELECT 2'
EXEC(@SQL)
SET @Rowcount = @@ROWCOUNT
SELECT @Rowcount
Then replace the 'SELECT 1 UNION SELECT 2' with your actual select without the count. I'd suggest just putting 1 in your select, like this:
SELECT 1
FROM dbo.Comm_Services
WHERE....
....
(as opposed to putting SELECT *)
Hope that helps.
A quick example of code for Application.Dispatcher.UnhandledException:
public App() {
this.Dispatcher.UnhandledException += OnDispatcherUnhandledException;
}
void OnDispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e) {
string errorMessage = string.Format("An unhandled exception occurred: {0}", e.Exception.Message);
MessageBox.Show(errorMessage, "Error", MessageBoxButton.OK, MessageBoxImage.Error);
// OR whatever you want like logging etc. MessageBox it's just example
// for quick debugging etc.
e.Handled = true;
}
I added this code in App.xaml.cs
From your comments:
A consequence is that, if you have multiple forms submitting to the same script, you can't rely on submit buttons to distinguish them.
I drop an <input type="hidden" value="form_name" />
into each form.
If submitting with javascript: add submit events to forms, not click events to their buttons. Saavy users don't touch their mouse very often.
I tried following steps to run mysql server 5.6 on my windows 8.
First initialize Property values
MutablePropertyValues mutablePropertyValues = new MutablePropertyValues();
mutablePropertyValues.add("hostName", details.getHostName());
mutablePropertyValues.add("port", details.getPort());
DefaultListableBeanFactory context = new DefaultListableBeanFactory();
GenericBeanDefinition connectionFactory = new GenericBeanDefinition();
connectionFactory.setBeanClass(Class);
connectionFactory.setPropertyValues(mutablePropertyValues);
context.registerBeanDefinition("beanName", connectionFactory);
Add to the list of beans
ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext).getBeanFactory();
beanFactory.registerSingleton("beanName", context.getBean("beanName"));
scanf("%s",str)
scans only until it finds a whitespace character. With the input "A 1"
, it will scan only the first character, hence s2
points at the garbage that happened to be in str
, since that array wasn't initialised.
There actually is a trick how to execute a parallel operation in a specific fork-join pool. If you execute it as a task in a fork-join pool, it stays there and does not use the common one.
final int parallelism = 4;
ForkJoinPool forkJoinPool = null;
try {
forkJoinPool = new ForkJoinPool(parallelism);
final List<Integer> primes = forkJoinPool.submit(() ->
// Parallel task here, for example
IntStream.range(1, 1_000_000).parallel()
.filter(PrimesPrint::isPrime)
.boxed().collect(Collectors.toList())
).get();
System.out.println(primes);
} catch (InterruptedException | ExecutionException e) {
throw new RuntimeException(e);
} finally {
if (forkJoinPool != null) {
forkJoinPool.shutdown();
}
}
The trick is based on ForkJoinTask.fork
which specifies: "Arranges to asynchronously execute this task in the pool the current task is running in, if applicable, or using the ForkJoinPool.commonPool()
if not inForkJoinPool()
"
The simplest way I found is it that includes host/path/query and
works in Controllers
(Cakephp 3.4
):
Cake\View\Helper\UrlHelper::build($this->request->getRequestTarget());
which returns something like this (we use it as login callback url) :
http://192.168.0.57/archive?melkId=12
this is my solution, you can set on an item (or a group) and deselect it with another click:
private final ArrayList<Integer> seleccionados = new ArrayList<>();
@Override
public void onBindViewHolder(final ViewHolder viewHolder, final int i) {
viewHolder.san.setText(android_versions.get(i).getAndroid_version_name());
if (!seleccionados.contains(i)){
viewHolder.inside.setCardBackgroundColor(Color.LTGRAY);
}
else {
viewHolder.inside.setCardBackgroundColor(Color.BLUE);
}
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (seleccionados.contains(i)){
seleccionados.remove(seleccionados.indexOf(i));
viewHolder.inside.setCardBackgroundColor(Color.LTGRAY);
} else {
seleccionados.add(i);
viewHolder.inside.setCardBackgroundColor(Color.BLUE);
}
}
});
}
The password that you use to login to github.com portal does not work in VS Code CLI/Shell. You should copy PAT Token from URL https://github.com/settings/tokens by generating new token and paste that string in CLI as password.
Going back to the __getattribute__ function; if the default implementation was not overridden; the following checks are done when executing the method:
This is the actual implementation of the object.__getattribute__ method:
.. c:function:: PyObject* PyObject_GenericGetAttr(PyObject *o, PyObject *name) Generic attribute getter function that is meant to be put into a type object's tp_getattro slot. It looks for a descriptor in the dictionary of classes in the object's MRO as well as an attribute in the object's :attr:~object.dict (if present). As outlined in :ref:descriptors, data descriptors take preference over instance attributes, while non-data descriptors don't. Otherwise, an :exc:AttributeError is raised.
Current date and time
$current_date_time = date('Y-m-d H:i:s');
15 min ago Date and time
$newTime = date("Y-m-d H:i:s",strtotime("+15 minutes", strtotime($current_date)));
if you getting this type of error so I suggest you used to stored proc data as usual list then binding the other controls because I also get this error so I solved it like this ex:-
repeater.DataSource = data.SPBinsReport().Tolist();
repeater.DataBind();
try like this
A solution using awk
:
$ ms=10000001; awk -v ms=$ms 'BEGIN {x=ms/1000;
s=x%60; x/=60;
m=x%60; x/=60;
h=x%60;
printf("%02d:%02d:%02d.%03d\n", h, m, s, ms%1000)}'

If you want to reverse the calculated binary form , you can use the StringBuffer class and simply use the reverse() method . Here is a sample program that will explain its use and calculate the binary
public class Binary {
public StringBuffer calculateBinary(int number) {
StringBuffer sBuf = new StringBuffer();
int temp = 0;
while (number > 0) {
temp = number % 2;
sBuf.append(temp);
number = number / 2;
}
return sBuf.reverse();
}
}
public class Main {
public static void main(String[] args) throws IOException {
System.out.println("enter the number you want to convert");
BufferedReader bReader = new BufferedReader(newInputStreamReader(System.in));
int number = Integer.parseInt(bReader.readLine());
Binary binaryObject = new Binary();
StringBuffer result = binaryObject.calculateBinary(number);
System.out.println(result);
}
}
// iterate over the map
for(Entry<String, ArrayList<String>> entry : test1.entrySet()){
// iterate over each entry
for(String item : entry.getValue()){
// print the map's key with each value in the ArrayList
System.out.println(entry.getKey() + ": " + item);
}
}
If you're looking to get promise in resource call, you should use
Regions.query().$q.then(function(){ .... })
Update : the promise syntax is changed in current versions which reads
Regions.query().$promise.then(function(){ ..... })
Those who have downvoted don't know what it was and who first added this promise to resource object. I used this feature in late 2012 - yes 2012.

I my case the reason for the
ERROR 2013 (HY000): Lost connection to MySQL server during query
error was that parts of my table were corrupted. I was also not able to mysqldump
my table because some rows broke it.
The error was not related to any memory issues etc. like mentioned above.
The nice thing was that MySQL returned me the row number which was the first what failed. It was something like
mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table mytable at row: 12723
The solution was to copy the data into a new table. In my case I lost 10 rows of data because i had to skip these corrupted rows. First I created a "tmp" table with the schema of the old one. SHOW CREATE TABLE
is your friend here. E.g.
SHOW CREATE TABLE mydatabase.mytable;
With the i created the new table. Let's call it mytabletmp. And then copy the rows you are able to copy via e.g.
insert into mysqltabletmp select * from mytable where id < 12723;
insert into mysqltabletmp select * from mytable where id > 12733;
After that drop old table, rename tmp-table to the old table name.
There are also some nice Information from Peter regarding this problem.
I have three answers to this question:
It is against user experience UX best practice to use BLOB and CLOB data types in string and retrieving binary data from an SQL database thus it is advised that you use the technique that involves storing the URL for the image( or any Binary file in the database). This URL will help the user application to retrieve and use this binary file.
Second the BLOB and CLOB data types are only available to a number of SQL versions thus functions such as LOAD_FILE or the datatypes themselves could miss in some versions.
Third DON'T USE BLOB OR CLOB. Store the URL; let the user application access the binary file from a folder in the project directory.
I had a similar issue for setting proxy server on a container.
The solution I'm using is an entrypoint script, and another script for environment variables configuration. Using RUN, you assure the configuration script runs on build, and ENTRYPOINT when you run the container.
--build-arg is used on command line to set proxy user and password.
As I need the same environment variables on container startup, I used a file to "persist" it from build to run.
The entrypoint script looks like:
#!/bin/bash
# Load the script of environment variables
. /root/configproxy.sh
# Run the main container command
exec "$@"
configproxy.sh
#!/bin/bash
function start_config {
read u p < /root/proxy_credentials
export HTTP_PROXY=http://$u:[email protected]:8080
export HTTPS_PROXY=https://$u:[email protected]:8080
/bin/cat <<EOF > /etc/apt/apt.conf
Acquire::http::proxy "http://$u:[email protected]:8080";
Acquire::https::proxy "https://$u:[email protected]:8080";
EOF
}
if [ -s "/root/proxy_credentials" ]
then
start_config
fi
And in the Dockerfile, configure:
# Base Image
FROM ubuntu:18.04
ARG user
ARG pass
USER root
# -z the length of STRING is zero
# [] are an alias for test command
# if $user is not empty, write credentials file
RUN if [ ! -z "$user" ]; then echo "${user} ${pass}">/root/proxy_credentials ; fi
#copy bash scripts
COPY configproxy.sh /root
COPY startup.sh .
RUN ["/bin/bash", "-c", ". /root/configproxy.sh"]
# Install dependencies and tools
#RUN apt-get update -y && \
# apt-get install -yqq --no-install-recommends \
# vim iputils-ping
ENTRYPOINT ["./startup.sh"]
CMD ["sh", "-c", "bash"]
Build without proxy settings
docker build -t img01 -f Dockerfile .
Build with proxy settings
docker build -t img01 --build-arg user=<USER> --build-arg pass=<PASS> -f Dockerfile .
Take a look here.
It's possible.
First, just add each column the usual way (as the last column).
Secondly, in SQL Server Management Studio
Get into Tools => Options.
Under 'Designers' Tab => 'Table and Database Designers' menu, uncheck the option 'Prevent saving changes that require table re-creation'.
Afterwards, right click on your table and choose 'Design'. In 'Design' mode just drag the columns to order them.
Don't forget to save.
If you are dealing with a previously bound date picker then setting
$("#datepicker").datepicker({ minDate: 0 });
will not work. That syntax is applicable only when you are creating the widget.
To set min date for a bound date picker use the following:
$("#datePicker").datepicker("option", "minDate", 0);
Here's some pure-Python code you can use to calculate the mean and standard deviation.
All code below is based on the statistics
module in Python 3.4+.
def mean(data):
"""Return the sample arithmetic mean of data."""
n = len(data)
if n < 1:
raise ValueError('mean requires at least one data point')
return sum(data)/n # in Python 2 use sum(data)/float(n)
def _ss(data):
"""Return sum of square deviations of sequence data."""
c = mean(data)
ss = sum((x-c)**2 for x in data)
return ss
def stddev(data, ddof=0):
"""Calculates the population standard deviation
by default; specify ddof=1 to compute the sample
standard deviation."""
n = len(data)
if n < 2:
raise ValueError('variance requires at least two data points')
ss = _ss(data)
pvar = ss/(n-ddof)
return pvar**0.5
Note: for improved accuracy when summing floats, the statistics
module uses a custom function _sum
rather than the built-in sum
which I've used in its place.
Now we have for example:
>>> mean([1, 2, 3])
2.0
>>> stddev([1, 2, 3]) # population standard deviation
0.816496580927726
>>> stddev([1, 2, 3], ddof=1) # sample standard deviation
0.1
If you want to use default value for a DateTime parameter in a method, you can only use default(DateTime).
The following line will not compile:
private void MyMethod(DateTime syncedTime = DateTime.MinValue)
This line will compile:
private void MyMethod(DateTime syncedTime = default(DateTime))
If you need to compare only day of month value than you can use the following code:
if yourdate.day == datetime.today().day:
# do something
If you need to check that the difference between two dates is acceptable then you can use timedelta:
if (datetime.today() - yourdate).days == 0:
#do something
And if you want to compare date part only than you can simply use:
from datetime import datetime, date
if yourdatetime.date() < datetime.today().date()
# do something
Note that timedelta has the following format:
datetime.timedelta([days[, seconds[, microseconds[, milliseconds[, minutes[, hours[, weeks]]]]]]])
So you are able to check diff in days, seconds, msec, minutes and so on depending on what you really need:
from datetime import datetime
if (datetime.today() - yourdate).days == 0:
#do something
In your case when you need to check that two dates are exactly the same you can use timedelta(0):
from datetime import datetime, timedelta
if (datetime.today() - yourdate) == timedelta(0):
#do something
An older post contains code for a method to resize your UIImage. The relevant portion is as follows:
+ (UIImage*)imageWithImage:(UIImage*)image
scaledToSize:(CGSize)newSize;
{
UIGraphicsBeginImageContext( newSize );
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
As far as cropping goes, I believe that if you alter the method to use a different size for the scaling than for the context, your resulting image should be clipped to the bounds of the context.
Just change the DropDownStyle
to DropDownList
. Or if you want it completely read only you can set Enabled = false
, or if you don't like the look of that I sometimes have two controls, one readonly textbox and one combobox and then hide the combo and show the textbox if it should be completely readonly and vice versa.
Your code should work, but I'm aware that answer doesn't help you. You can see a working example here (jsfiddle).
Jquery:
$(document).on('click','#test-element',function(){
alert("You clicked the element with and ID of 'test-element'");
});
As someone already pointed out, you are using an ID instead of a class. If you have more that one element on the page with an ID, then jquery will return only the first element with that ID. There won't be any errors because that's how it works. If this is the problem, then you'll notice that the click event works for the first test-element
but not for any that follow.
If this does not accurately describe the symptoms of the problem, then perhaps your selector is wrong. Your update leads me to believe this is the case because of inspecting an element then clicking the page again and triggering the click. What could be causing this is if you put the event listener on the actual document
instead of test-element
. If so, when you click off the document and back on (like from the developer window back to the document) the event will trigger. If this is the case, you'll also notice the click event is triggered if you click between two different tabs (because they are two different document
s and therefore you are clicking the document.
If neither of these are the answer, posting HTML will go a long way toward figuring it out.
if you are using Swift Mailer: please ensure that your $transport variable is similar to the below, based on tests i have done, that error results from ssl and port misconfiguration. note: you must include 'ssl' or 'tls' in the transport variable.
EXAMPLE CODE:
// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))
->setUsername([email protected])
->setPassword(password)
;
// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);
// Create a message
$message = (new Swift_Message('News Letter Subscription'))
->setFrom(['[email protected]' => 'A Name'])
->setTo(['[email protected]' => 'A Name'])
->setBody('your message body')
;
// Send the message
$result = $mailer->send($message);
In order to get npm start
running for me, I had to make sure I had globally installed some of the devDependencies. Have you tried:
npm install -g concurrently

Among the built-in HTTP handlers there are also Web service handler (*.asmx
) and Trace handler (trace.axd
)
MSDN says:
An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler.
The image below illustrates this:
As to your second question:
Does ashx handle more connections than aspx?
Don't think so (but for sure, at least not less than).
Starting in NumPy version 1.10, we have the method stack. It can stack arrays of any dimension (all equal):
# List of arrays.
L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]
# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True
M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)
# This are all true
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

2017 Update - since WooCommerce 3:
global $product;
$id = $product->get_id();
Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.
I was facing this error while I deployed my Web API project locally and I was calling API project only with this URL given below:
localhost//myAPIProject
Since the error message says it is not http:// then I changed the URL and put a prefix http as given below and the error was gone.
<div class="form-group">
<label asp-for="Password"></label>
<input asp-for="Password" value="Pass@123" readonly class="form-control" />
<span asp-validation-for="Password" class="text-danger"></span>
</div>
use : value="Pass@123" for default value in input in .net core
General sibling combinator
The general sibling combinator selector is very similar to the adjacent sibling combinator selector. The difference is that the element being selected doesn't need to immediately succeed the first element, but can appear anywhere after it.
BundleConfig
is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)
To add this file, first you need to add the Microsoft.AspNet.Web.Optimization
nuget package to your web project:
Install-Package Microsoft.AspNet.Web.Optimization
Then under the App_Start folder create a new cs file called BundleConfig.cs
. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):
using System.Web;
using System.Web.Optimization;
namespace CodeRepository.Web
{
public class BundleConfig
{
// For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate*"));
// Use the development version of Modernizr to develop with and learn from. Then, when you're
// ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
"~/Scripts/modernizr-*"));
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js"));
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));
}
}
}
Then modify your Global.asax and add a call to RegisterBundles()
in Application_Start()
:
using System.Web.Optimization;
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}

There is nothing bad or better, It just depends on the precedence of operators. Since ||
has higher precedence than or
, so ||
is mostly used.
With this version of python 3:
/opt/anaconda3/bin/python --version
Python 3.6.0 :: Anaconda 4.3.0 (64-bit)
Looking at the details of the error, I found the lines of codes causing the failure:
/opt/anaconda3/lib/python3.6/site-packages/sklearn/utils/validation.py in _assert_all_finite(X)
56 and not np.isfinite(X).all()):
57 raise ValueError("Input contains NaN, infinity"
---> 58 " or a value too large for %r." % X.dtype)
59
60
ValueError: Input contains NaN, infinity or a value too large for dtype('float64').
From this, I was able to extract the correct way to test what was going on with my data using the same test which fails given by the error message: np.isfinite(X)
Then with a quick and dirty loop, I was able to find that my data indeed contains nans
:
print(p[:,0].shape)
index = 0
for i in p[:,0]:
if not np.isfinite(i):
print(index, i)
index +=1
(367340,)
4454 nan
6940 nan
10868 nan
12753 nan
14855 nan
15678 nan
24954 nan
30251 nan
31108 nan
51455 nan

...
Now all I have to do is remove the values at these indexes.
You can use sftp to mount the remote directory on your location machine and then simply open the files using Sublime text the way you normally would.
To mount remote directory using sftp, enter the following on your Linux file manager;
sftp://user@remote_box.com:22/home/user/code_directory
It might seem slow depending on your internet speeds. But this worked for me.
This solved my problem:
sudo rm /usr/local/cuda/bin/gcc
sudo rm /usr/local/cuda/bin/g++
sudo apt install gcc-4.4 g++-4.4
sudo ln -s /usr/bin/gcc-4.4 /usr/local/cuda/bin/gcc
sudo ln -s /usr/bin/g++-4.4 /usr/local/cuda/bin/g++
You will need to cast or convert the values to decimal before division. Take a look at this http://msdn.microsoft.com/en-us/library/aa226054.aspx
For example
DECLARE @num1 int = 3 DECLARE @num2 int = 2
SELECT @num1/@num2
SELECT @num1/CONVERT(decimal(4,2), @num2)
The first SELECT will result in what you're seeing while the second SELECT will have the correct answer 1.500000
You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:
SELECT
student.firstname,
student.lastname,
exam.name,
exam.date,
grade.grade
FROM grade
INNER JOIN student
ON student.studentId = grade.fk_studentId
INNER JOIN exam
ON exam.examId = grade.fk_examId
GROUP BY grade.gradeId
ORDER BY exam.date
You could set echo to on:
set echo on

operatorThis question age is about 10 years and it is surprising that nobody mention about this yet - however some people see the problem when we use delete
operator (e.g here). This is also a little bit counter intuitive solution but the in
operator which works in 'object world' can also work with arrays (because we can look on array indexes like on 'keys'...). In this way we can detect and distinct between undefined
array value and value (index) removed by delete
if(index in arrayName) {
// do stuff
}
let arr = [0, 1, 2, 3, null, undefined,6]
delete arr[2]; // we delete element at index=2
if(2 in arr) console.log('You will not see this because idx 2 was deleted');
if(5 in arr) console.log('This is element arr[5]:', arr[5]);
// Whole array and indexes bigger than arr.length:
for(let i=0; i<=9; i++) {
let val = (i in arr) ? arr[i] : 'empty'
let bound = i<arr.length ? '' : '(out of range)'
console.log(`${i} value: `, val, bound);
}
console.log('Look on below aray on chrome console (not in SO snippet console)');
console.log('typeof arr:', typeof arr);
console.log(arr);
_x000D_
Chrome console reveals some info about snippet array with deleted index 2 - this index actually not exists at all (!!!) (same way as key is removed from object). What is also interesting here array is viewd as key-value pairs (we even see 'length' key). It is also interesting that typeof arr
is Object (!!!), the delete
and in
operator works like for JS objects
(also square brackets notation arr[idx]
and obj[key]
is similar) - so it looks like array is some special JS object in the core.
To get similar effect without delete
define array as follows
[0, 1,, 3, null, undefined, 6] // pay attention to double comma: ",,"
The "this" is already coloured in Javascript.
View->Syntax-> and choose your language to highlight.
Maybe this one can help:

I will recommend to use an alternative method using seaborn
which more powerful tool for data plotting. You can use seaborn scatterplot
and define colum 3 as hue
and size
.
Working code:
import pandas as pd
import seaborn as sns
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20),'col_name_3': np.arange(20)*100}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df, hue="col_name_3",size="col_name_3")
Sometimes, you want to have variables that are common to all objects. This is accomplished with the static modifier.
i.e. class human - number of heads (1) is static, same for all humans, however human - haircolor is variable for each human.
Notice that static vars can also be used to share information across all instances
A simple fix that I use to add space in horizontal legends, simply add spaces in the labels (see extract below):
scale_fill_manual(values=c("red","blue","white"),
labels=c("Label of category 1 ",
"Label of category 2 ",
"Label of category 3"))
import time
start_time = time.clock()
main()
print time.clock() - start_time, "seconds"
time.clock()
returns the processor time, which allows us to calculate only the time used by this process (on Unix anyway). The documentation says "in any case, this is the function to use for benchmarking Python or timing algorithms"
In python:
def lcm(*args):
"""Calculates lcm of args"""
biggest = max(args) #find the largest of numbers
rest = [n for n in args if n != biggest] #the list of the numbers without the largest
factor = 1 #to multiply with the biggest as long as the result is not divisble by all of the numbers in the rest
while True:
#check if biggest is divisble by all in the rest:
ans = False in [(biggest * factor) % n == 0 for n in rest]
#if so the clm is found break the loop and return it, otherwise increment factor by 1 and try again
if not ans:
break
factor += 1
biggest *= factor
return "lcm of {0} is {1}".format(args, biggest)
>>> lcm(100,23,98)
'lcm of (100, 23, 98) is 112700'
>>> lcm(*range(1, 20))
'lcm of (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19) is 232792560'
It can be easily done by setting a ChangeFlag to true, on onChange event of TextArea. Use javascript to show confirm dialog box based on the ChangeFlag value. Discard the form and navigate to requested page if confirm returns true, else do-nothing.

The solution above not working for the latest version on PostgreSQL. I found this way to convert epoch time being stored in number and int column type is on PostgreSQL 13:
SELECT TIMESTAMP 'epoch' + (<table>.field::int) * INTERVAL '1 second' as started_on from <table>;
For more detail explanation, you can see here https://www.yodiw.com/convert-epoch-time-to-timestamp-in-postgresql/#more-214
Carry Flag is a flag set when:
a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.
b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.
Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)
Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.
You can read more about flags on wikipedia

First of all, don't use char*
or char[N]
. Use std::string
, then everything else becomes so easy!
Examples,
std::string s = "Hello";
std::string greet = s + " World"; //concatenation easy!
Easy, isn't it?
Now if you need char const *
for some reason, such as when you want to pass to some function, then you can do this:
some_c_api(s.c_str(), s.size());
assuming this function is declared as:
some_c_api(char const *input, size_t length);
Explore std::string

const char * a;
a
is writable, but *a
is not; in other words, you can modify a

Note that this is identical to
char const * a;
In this case, a
is a pointer to a const char

An elegant way to move your file to an nonexistent directory is to create the following extension to native FileInfo class:
public static class FileInfoExtension
{
//second parameter is need to avoid collision with native MoveTo
public static void MoveTo(this FileInfo file, string destination, bool autoCreateDirectory) {
if (autoCreateDirectory)
{
var destinationDirectory = new DirectoryInfo(Path.GetDirectoryName(destination));
if (!destinationDirectory.Exists)
destinationDirectory.Create();
}
file.MoveTo(destination);
}
}
Then use brand new MoveTo extension:
using <namespace of FileInfoExtension>;
...
new FileInfo("some path")
.MoveTo("target path",true);

I'm trying to re-order the list based on a property inside my model,
allEmployees = new List<Employee>(allEmployees.OrderByDescending(employee => employee.Name));
but I faced a problem when a small and capital letters exist
, so to solve it, I used the string comparer.
allEmployees.OrderBy(employee => employee.Name,StringComparer.CurrentCultureIgnoreCase)
Alternatively, setting a session variable before the redirect and test it in the destination url, can solve this problem for me.

If it can be done with a batch file then the maybe over complicated work around is have c# write a .bat file and run it. If you want user input you could place the input into a variable and have c# write it into the file. it will take trial and error with this way because its like controlling a puppet with another puppet.
here is an example, In this case the function is for a push button in windows forum app that clears the print queue.
using System.IO;
using System;
public static void ClearPrintQueue()
{
//this is the path the document or in our case batch file will be placed
string docPath =
Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
//this is the path process.start usues
string path1 = docPath + "\\Test.bat";
// these are the batch commands
// remember its "", the comma separates the lines
string[] lines =
{
"@echo off",
"net stop spooler",
"del %systemroot%\\System32\\spool\\Printers\\* /Q",
"net start spooler",
//this deletes the file
"del \"%~f0\"" //do not put a comma on the last line
};
//this writes the string to the file
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "test.bat")))
{
//This writes the file line by line
foreach (string line in lines)
outputFile.WriteLine(line);
}
System.Diagnostics.Process.Start(path1);
}
IF you want user input then you could try something like this.
This is for setting the computer IP as static but asking the user what the IP, gateway, and dns server is.
you will need this for it to work
public static void SetIPStatic()
{
//These open pop up boxes which ask for user input
string STATIC = Microsoft.VisualBasic.Interaction.InputBox("Whats the static IP?", "", "", 100, 100);
string SUBNET = Microsoft.VisualBasic.Interaction.InputBox("Whats the Subnet?(Press enter for default)", "255.255.255.0", "", 100, 100);
string DEFAULTGATEWAY = Microsoft.VisualBasic.Interaction.InputBox("Whats the Default gateway?", "", "", 100, 100);
string DNS = Microsoft.VisualBasic.Interaction.InputBox("Whats the DNS server IP?(Input required, 8.8.4.4 has already been set as secondary)", "", "", 100, 100);
//this is the path the document or in our case batch file will be placed
string docPath =
Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
//this is the path process.start usues
string path1 = docPath + "\\Test.bat";
// these are the batch commands
// remember its "", the comma separates the lines
string[] lines =
{
"SETLOCAL EnableDelayedExpansion",
"SET adapterName=",
"FOR /F \"tokens=* delims=:\" %%a IN ('IPCONFIG ^| FIND /I \"ETHERNET ADAPTER\"') DO (",
"SET adapterName=%%a",
"REM Removes \"Ethernet adapter\" from the front of the adapter name",
"SET adapterName=!adapterName:~17!",
"REM Removes the colon from the end of the adapter name",
"SET adapterName=!adapterName:~0,-1!",
//the variables that were set before are used here
"netsh interface ipv4 set address name=\"!adapterName!\" static " + STATIC + " " + STATIC + " " + DEFAULTGATEWAY,
"netsh interface ipv4 set dns name=\"!adapterName!\" static " + DNS + " primary",
"netsh interface ipv4 add dns name=\"!adapterName!\" 8.8.4.4 index=2",
")",
"ipconfig /flushdns",
"ipconfig /registerdns",
":EOF",
"DEL \"%~f0\"",
""
};
//this writes the string to the file
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "test.bat")))
{
//This writes the file line by line
foreach (string line in lines)
outputFile.WriteLine(line);
}
System.Diagnostics.Process.Start(path1);
}
Like I said. It may be a little overcomplicated but it never fails unless I write the batch commands wrong.
The top answer by @eski is good, but the code is not elegant to use, so I wrote a groovy script in gradle for general use. It's applied to all build type and product flavor and not only can be use for layout, you can also add subfolder for any other resources type such as drawable. Here is the code(put it in android
block of project-level gradle file):
sourceSets.each {
def rootResDir = it.res.srcDirs[0]
def getSubDirs = { dirName ->
def layoutsDir = new File(rootResDir, dirName)
def subLayoutDirs = []
if (layoutsDir.exists()) {
layoutsDir.eachDir {
subLayoutDirs.add it
}
}
return subLayoutDirs
}
def resDirs = [
"anims",
"colors",
"drawables",
"drawables-hdpi",
"drawables-mdpi",
"drawables-xhdpi",
"drawables-xxhdpi",
"layouts",
"valuess",
]
def srcDirs = resDirs.collect {
getSubDirs(it)
}
it.res.srcDirs = [srcDirs, rootResDir]
}
How to do in practice?
For example, I want to create subfolder named activity
for layout
, add a string by any name in resDirs
variable such as layouts
, then the layout xml file should be put in res\layouts\activity\layout\xxx.xml
.
If I want to create subfolder named selectors
for drawable
, add a string by any name in resDirs
variable such as drawables
, then the drawable xml file should be put in res\drawables\selectors\drawable\xxx.xml
.
The folder name such as layouts
and drawables
is defined in resDirs
variable, it can be any string.
All subfolder created by you such as activity
or selectors
are regarded as the same as res
folder. So in selectors
folder, we must create drawable
folder additionally and put xml files in drawable
folder, after that gradle can recognize the xml files as drawable normally.

altogether (as there are some roots that this algorithm will take many iterations for).

double temp=0;
while(fabs(num - (temp * temp)) > SOME_SMALL_VALUE)
{
temp = (lower_bound+upper_bound)/2;
if (temp*temp >= num)
{
upper_bound = temp;
}
else
{
lower_bound = temp;
}
}
return temp;
}
I just encountered the similar problem and found a series of steps did help me. Of course few of them is to Change the network to a stronger,better one.or if you have only one network then try Reconnecting to the network and then simply INVALIDATE/RESTART your android studio. If it still shows the error you need to add the "maven" in repositories and point it out to the link as shown below: maven { url "http://jcenter.bintray.com"}
Finally,Go to *File *Settings *Build,Execution and deployment *Gradle *Android Studio --------And check Enable maven repository option.
After that simply clean and rebuild your APP and you will be good to go.
Alternatively, I would suggest turning interactive on in the beginning and at the very last plot, turn it off. All will show up, but they will not disappear as your program will stay around until you close the figures.

... code to make figure (1)

interactive(False)
plt.show()
It is because it's being converted from a binary representation. Just because it has printed all those decimal digits doesn't mean it can represent all decimal values to that precision. Take, for example, this in Python:
>>> 0.14285714285714285
0.14285714285714285
>>> 0.14285714285714286
0.14285714285714285
Notice how I changed the last digit, but it printed out the same number anyway.

DECLARE @test nvarchar(100)
SET @test = 'Foreign Tax Credit - 1997'
SELECT @test, left(@test, charindex('-', @test) - 2) AS LeftString,
right(@test, len(@test) - charindex('-', @test) - 1) AS RightString
Interestingly, if I use
get-wmiobject -class Win32_Environment -filter "Name='PROCESSOR_ARCHITECTURE'"
I get AMD64 in both 32-bit and 64-bit ISE (on Win7 64-bit).
You can use extend
method in list operations as well.
>>> list1 = []
>>> list1.extend('somestring')
>>> list1
['s', 'o', 'm', 'e', 's', 't', 'r', 'i', 'n', 'g']
Use .val()
instead of .innerHTML
for getting value of selected option
Use .text()
for getting text of selected option
Thanks for correcting :)
There is another option which i haven't seen here and which doesn't involve "complex" Objects or Collections.
String[] array1 = new String[]{"one", "two"};
String[] array2 = new String[]{"three"};
String[] array = new String[array1.length + array2.length];
System.arraycopy(array1, 0, array, 0, array1.length);
System.arraycopy(array2, 0, array, array1.length, array2.length);
Dim f as Range
Set f=ActiveSheet.Cells.Find(...)
If Not f Is Nothing then
msgbox "Row=" & f.Row & vbcrlf & "Column=" & f.Column
Else
msgbox "value not found!"
End If
or even more better, you can put this code in a class file
