Agreed with Yuri Tkachenko's answer.
I wanna point this out.
It's a pretty specific scenario. BUT it happens.
When you copy a gif before its loaded fully in some site like google images. it just gives the preview image address of that gif. Which is clearly not a gif.
So, make sure it ends with .gif extension
Here is an updated method with syntax that is more common in python code. It also prevents you from opening the same file multiple times.
import pandas as pd
sheet1, sheet2 = None, None
with pd.ExcelFile("PATH\FileName.xlsx") as reader:
sheet1 = pd.read_excel(reader, sheet_name='Sheet1')
sheet2 = pd.read_excel(reader, sheet_name='Sheet2')

If you are debugging and wasting time like me, this will give exact details including passwords. :P

I liked cocogza's answer except that calling base.IsValid resulted in a stack overflow exception as it would re-enter the IsValid method again and again. So I modified it to be for a specific type of validation, in my case it was for an e-mail address.
[AttributeUsage(AttributeTargets.Property)]
class ValidEmailAddressIfTrueAttribute : ValidationAttribute
{
private readonly string _nameOfBoolProp;
public ValidEmailAddressIfTrueAttribute(string nameOfBoolProp)
{
_nameOfBoolProp = nameOfBoolProp;
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (validationContext == null)
{
return null;
}
var property = validationContext.ObjectType.GetProperty(_nameOfBoolProp);
if (property == null)
{
return new ValidationResult($"{_nameOfBoolProp} not found");
}
var boolVal = property.GetValue(validationContext.ObjectInstance, null);
if (boolVal == null || boolVal.GetType() != typeof(bool))
{
return new ValidationResult($"{_nameOfBoolProp} not boolean");
}
if ((bool)boolVal)
{
var attribute = new EmailAddressAttribute {ErrorMessage = $"{value} is not a valid e-mail address."};
return attribute.GetValidationResult(value, validationContext);
}
return null;
}
}
This works much better! It doesn't crash and produces a nice error message. Hope this helps someone!
For Linux the easiest way to get is,
dpkg -l | grep "perl"
a=[100,200,300,400,500]
def search(b):
try:
k=a.index(b)
return a[k]
except ValueError:
return 'not found'
print(search(500))
it'll return the object if found else it'll return "not found"
This example shows how to use the method GetInvocationList() to retrieve delegates to all the handlers that have been added. If you are looking to see if a specific handler (function) has been added then you can use array.
public class MyClass
{
event Action MyEvent;
}
...
MyClass myClass = new MyClass();
myClass.MyEvent += SomeFunction;
...
Action[] handlers = myClass.MyEvent.GetInvocationList(); //this will be an array of 1 in this example
Console.WriteLine(handlers[0].Method.Name);//prints the name of the method
You can examine various properties on the Method property of the delegate to see if a specific function has been added.
If you are looking to see if there is just one attached, you can just test for null.
Use package uniuri, which generates cryptographically secure uniform (unbiased) strings.

It can be this:
If you are using cpanel for your website smtp restrictions are problem and cause this error. SMTP Restrictions
select t.*
from (
select RequestID, max(CreatedDate) as MaxCreatedDate
from table1
group by RequestID
) tm
inner join table1 t on tm.RequestID = t.RequestID and tm.MaxCreatedDate = t.CreatedDate
Since this is a login div, shouldn't the default be to NOT display it. I am going to go ahead and assume then you want to display it then via javascript.
<div id="login" style="display:none;">Content</div>
Then using jQuery:
<script type="javascript">$('#login').show();</script>
Another method you might consider is something like this:
<div id="login" style="display:<%=SetDisplay() %>">Content</div>
And the SetDisplay() method output "none" or "block"
This is the function that you need: Then just pass the x in a rename(X) and it will rename all values that appear and if it isn't in there it won't error
rename <-function(x){
oldNames = c("a","b","c")
newNames = c("d","e","f")
existing <- match(oldNames,names(x))
names(x)[na.omit(existing)] <- newNames[which(!is.na(existing))]
return(x)
}
In case it helps anyone I had the same error. It turns out my page had not been scrapped by Facebook in awhile and it was an old error. There was a scrape again button on the page that fixed it.
Also for openCV in python you can do:

Remove a block of code from multiple files
To expand on @Markus Olsson's answer, I needed to remove a block of code from multiple files. I had problems with Swedish characters in a core project, so I needed to install System.Text.CodePagesEncodingProvider nuget package and use System.Text.Encoding.GetEncoding(1252) instead of System.Text.Encoding.UTF8.
public static void Main(string[] args)
{
try
{
var dir = @"C:\Test";
//Get all html and htm files
var files = DirSearch(dir);
foreach (var file in files)
{
RmCode(file);
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
throw;
}
}
private static void RmCode(string file)
{
string tempFile = Path.GetTempFileName();
using (var sr = new StreamReader(file, Encoding.UTF8))
using (var sw = new StreamWriter(new FileStream(tempFile, FileMode.Open, FileAccess.ReadWrite), Encoding.UTF8))
{
string line;
var startOfBadCode = "<div>";
var endOfBadCode = "</div>";
var deleteLine = false;
while ((line = sr.ReadLine()) != null)
{
if (line.Contains(startOfBadCode))
{
deleteLine = true;
}
if (!deleteLine)
{
sw.WriteLine(line);
}
if (line.Contains(endOfBadCode))
{
deleteLine = false;
}
}
}
File.Delete(file);
File.Move(tempFile, file);
}
private static List<String> DirSearch(string sDir)
{
List<String> files = new List<String>();
try
{
foreach (string f in Directory.GetFiles(sDir))
{
files.Add(f);
}
foreach (string d in Directory.GetDirectories(sDir))
{
files.AddRange(DirSearch(d));
}
}
catch (System.Exception excpt)
{
Console.WriteLine(excpt.Message);
}
return files.Where(s => s.EndsWith(".htm") || s.EndsWith(".html")).ToList();
}
Preconditions: adb and wireshark is installed on your computer and you have a rooted android device.
adb push ~/Downloads/tcpdump /sdcard/
adb shell
su root
mv /sdcard/tcpdump /data/local/
cd /data/local/
chmod +x tcpdump
./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
CTRL+C
after you've captured enough packets.exit
exit
adb pull /sdcard/dump.pcap ~/Downloads/
Now you can open the pcap file using Wireshark.
I was looking for a way to sample a few members of the GroupBy obj - had to address the posted question to get this done.
some_key
columngrouped = df.groupby('some_key')
sampled_df_i = random.sample(grouped.indices, N)
df_list = map(lambda df_i: grouped.get_group(df_i), sampled_df_i)
sampled_df = pd.concat(df_list, axis=0, join='outer')
You can use your own code. You don't need to use the looping structure, if you don't want to use the looping structure as you said above. Only you have to focus to remove space or trim the String of the list.
If you are using java8 you can simply trim the String using the single line of the code:
myList = myList.stream().map(String :: trim).collect(Collectors.toList());
The importance of the above line is, in the future, you can use a List or set as well. Now you can use your own code:
if(myList.contains("A")){
//true
}else{
// false
}
Use the layout_weight
attribute. The layout will roughly look like this:
<LinearLayout android:orientation="horizontal"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<LinearLayout
android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="0dp"/>
<LinearLayout
android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="0dp"/>
</LinearLayout>
You wouldn't really want to do this given the existing Instr/InstrRev functions but there are times when it is handy to use EVALUATE to return the result of Excel worksheet functions within VBA
Option Explicit
Public Sub test()
Debug.Print ContainsSubString("bc", "abc,d")
End Sub
Public Function ContainsSubString(ByVal substring As String, ByVal testString As String) As Boolean
'substring = string to test for; testString = string to search
ContainsSubString = Evaluate("=ISNUMBER(FIND(" & Chr$(34) & substring & Chr$(34) & ", " & Chr$(34) & testString & Chr$(34) & "))")
End Function
With ES6 you can now do it like this
Example Codepen URl to load

ReactDOM.render(<App />, rootElement);
Edit on CodeSandbox:
I had similar problem, the solution for Windows looks the same (my Jenkins is installed on a Windows machine):
Global settings:
Go to Manage jenkins -> Configure System -> Git installations
add there the git exe path (for example: C:\Program Files\Git\bin\git.exe
), or you can use environment variable.
For Jenkins version 2.121.3, Go to Manage jenkins -> Global tool configuration -> Git installations -> Path to Git executable: C:\Program Files\Git\bin\git.exe
Jenkins job side:
Go to Source code Management -> select git, add your repository, choose connection to repository (http/ssh) and add credentials and it should work.
What I like doing is overriding ToString() so that I get more useful output beyond the type name. This is handy in the debugger, you can see the information you want about an object without needing to expand it.
Based on the List Members Instance docs, the easiest way is to use a PUT
request which according to the docs either "adds a new list member or updates the member if the email already exists on the list".
Furthermore apikey
is definitely not part of the json schema and there's no point in including it in your json request.
Also, as noted in @TooMuchPete's comment, you can use CURLOPT_USERPWD
for basic http auth as illustrated in below.
I'm using the following function to add and update list members. You may need to include a slightly different set of merge_fields
depending on your list parameters.
$data = [
'email' => '[email protected]',
'status' => 'subscribed',
'firstname' => 'john',
'lastname' => 'doe'
];
syncMailchimp($data);
function syncMailchimp($data) {
$apiKey = 'your api key';
$listId = 'your list id';
$memberId = md5(strtolower($data['email']));
$dataCenter = substr($apiKey,strpos($apiKey,'-')+1);
$url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listId . '/members/' . $memberId;
$json = json_encode([
'email_address' => $data['email'],
'status' => $data['status'], // "subscribed","unsubscribed","cleaned","pending"
'merge_fields' => [
'FNAME' => $data['firstname'],
'LNAME' => $data['lastname']
]
]);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
$result = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return $httpCode;
}
In C++-11 you can do:
std::vector<int> v = {0, 1, 2, 3, 4, 5};
for (auto i : v)
{
// access by value, the type of i is int
std::cout << i << ' ';
}
std::cout << '\n';

Using brew
First install brew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
And then install wget with brew:
brew install wget
Using MacPorts
First, download and run MacPorts installer (.pkg)
And then install wget:
sudo port install wget
This is another method which will definitely work, but I cant get it to read multiple text files to view in multiple textviews in a single activity, anyone can help?
TextView helloTxt = (TextView)findViewById(R.id.yourTextView);
helloTxt.setText(readTxt());
}
private String readTxt(){
InputStream inputStream = getResources().openRawResource(R.raw.yourTextFile);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
int i;
try {
i = inputStream.read();
while (i != -1)
{
byteArrayOutputStream.write(i);
i = inputStream.read();
}
inputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return byteArrayOutputStream.toString();
}
The steps in order to make a full check are:
Prepare the captor :
ArgumentCaptor<SomeArgumentClass> someArgumentCaptor = ArgumentCaptor.forClass(SomeArgumentClass.class);
verify the call to dependent on component (collaborator of subject under test). times(1) is the default value, so ne need to add it.
verify(dependentOnComponent, times(1)).send(someArgumentCaptor.capture());
Get the argument passed to collaborator
SomeArgumentClass someArgument = messageCaptor.getValue();
someArgument can be used for assertions
You have to define void swapCase before the main definition.
I was facing the same problem when import projects into IntelliJ.
for in my case first, check SDK details and check you have configured JDK correctly or not.
Go to File-> Project Structure-> platform Settings-> SDKs
Check your JDK is correct or not.
Next, I Removed project from IntelliJ and delete all IntelliJ and IDE related files and folder from the project folder (.idea, .settings, .classpath, dependency-reduced-pom). Also, delete the target folder and re-import the project.
The above solution worked in my case.
This function works as same as json_decode(json_encode($arr), false)
.
function arrayToObject(array $arr)
{
$flat = array_keys($arr) === range(0, count($arr) - 1);
$out = $flat ? [] : new \stdClass();
foreach ($arr as $key => $value) {
$temp = is_array($value) ? $this->arrayToObject($value) : $value;
if ($flat) {
$out[] = $temp;
} else {
$out->{$key} = $temp;
}
}
return $out;
}
$arr = ["a", "b", "c"];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));
Output:
array(
0 => 'a',
1 => 'b',
2 => 'c',
)
array(
0 => 'a',
1 => 'b',
2 => 'c',
)
$arr = [["a" => 1], ["a" => 1], ["a" => 1]];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));
Output:
array(
0 => stdClass::__set_state(array('a' => 1,)),
1 => stdClass::__set_state(array('a' => 1,)),
2 => stdClass::__set_state(array('a' => 1,)),
)
array(
0 => stdClass::__set_state(array('a' => 1,)),
1 => stdClass::__set_state(array('a' => 1,)),
2 => stdClass::__set_state(array('a' => 1,)),
)
$arr = ["a" => 1];
var_export(json_decode($arr));
var_export($this->arrayToObject($arr));
Output:
stdClass::__set_state(array('a' => 1,))
stdClass::__set_state(array('a' => 1,))
Handle intent on startCommand of service by using.
stopForeground(true)
This call will remove the service from foreground state, allowing it to be killed if more memory is needed. This does not stop the service from running. For that, you need to call stopSelf() or related methods.
Passing value true or false indicated if you want to remove the notification or not.
val ACTION_STOP_SERVICE = "stop_service"
val NOTIFICATION_ID_SERVICE = 1
...
override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
super.onStartCommand(intent, flags, startId)
if (ACTION_STOP_SERVICE == intent.action) {
stopForeground(true)
stopSelf()
} else {
//Start your task
//Send forground notification that a service will run in background.
sendServiceNotification(this)
}
return Service.START_NOT_STICKY
}
Handle your task when on destroy is called by stopSelf().
override fun onDestroy() {
super.onDestroy()
//Stop whatever you started
}
Create a notification to keep the service running in foreground.
//This is from Util class so as not to cloud your service
fun sendServiceNotification(myService: Service) {
val notificationTitle = "Service running"
val notificationContent = "<My app> is using <service name> "
val actionButtonText = "Stop"
//Check android version and create channel for Android O and above
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
//You can do this on your own
//createNotificationChannel(CHANNEL_ID_SERVICE)
}
//Build notification
val notificationBuilder = NotificationCompat.Builder(applicationContext, CHANNEL_ID_SERVICE)
notificationBuilder.setAutoCancel(true)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_location)
.setContentTitle(notificationTitle)
.setContentText(notificationContent)
.setVibrate(null)
//Add stop button on notification
val pStopSelf = createStopButtonIntent(myService)
notificationBuilder.addAction(R.drawable.ic_location, actionButtonText, pStopSelf)
//Build notification
val notificationManagerCompact = NotificationManagerCompat.from(applicationContext)
notificationManagerCompact.notify(NOTIFICATION_ID_SERVICE, notificationBuilder.build())
val notification = notificationBuilder.build()
//Start notification in foreground to let user know which service is running.
myService.startForeground(NOTIFICATION_ID_SERVICE, notification)
//Send notification
notificationManagerCompact.notify(NOTIFICATION_ID_SERVICE, notification)
}
Give a stop button on notification to stop the service when user needs.
/**

UIKit
uses the topLayoutGuide & bottomLayoutGuide which is UIView
propertyiOS11+ uses safeAreaLayoutGuide which is also UIView
property
Enable Safe Area Layout Guide check box from file inspector.
Safe areas help you place your views within the visible portion of the overall interface.
In tvOS, the safe area also includes the screen’s overscan insets, which represent the area covered by the screen’s bezel.
Use safe areas as an aid to laying out your content like UIButton
etc.
When designing for iPhone X, you must ensure that layouts fill the screen and aren't obscured by the device's rounded corners, sensor housing, or the indicator for accessing the Home screen.
Make sure backgrounds extend to the edges of the display, and that vertically scrollable layouts, like tables and collections, continue all the way to the bottom.
The status bar is taller on iPhone X than on other iPhones. If your app assumes a fixed status bar height for positioning content below the status bar, you must update your app to dynamically position content based on the user's device. Note that the status bar on iPhone X doesn't change height when background tasks like voice recording and location tracking are active
print(UIApplication.shared.statusBarFrame.height)//44 for iPhone X, 20 for other iPhones
Height of home indicator container is 34 points.
Once you enable Safe Area Layout Guide you can see safe area constraints property listed in the interface builder.
You can set constraints with respective of self.view.safeAreaLayoutGuide
as-
ObjC:
self.demoView.translatesAutoresizingMaskIntoConstraints = NO;
UILayoutGuide * guide = self.view.safeAreaLayoutGuide;
[self.demoView.leadingAnchor constraintEqualToAnchor:guide.leadingAnchor].active = YES;
[self.demoView.trailingAnchor constraintEqualToAnchor:guide.trailingAnchor].active = YES;
[self.demoView.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
[self.demoView.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;
Swift:
demoView.translatesAutoresizingMaskIntoConstraints = false
if #available(iOS 11.0, *) {
let guide = self.view.safeAreaLayoutGuide
demoView.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
demoView.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
demoView.bottomAnchor.constraint(equalTo: guide.bottomAnchor).isActive = true
demoView.topAnchor.constraint(equalTo: guide.topAnchor).isActive = true
} else {
NSLayoutConstraint(item: demoView, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1.0, constant: 0).isActive = true
NSLayoutConstraint(item: demoView, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1.0, constant: 0).isActive = true
NSLayoutConstraint(item: demoView, attribute: .bottom, relatedBy: .equal, toItem: view, attribute: .bottom, multiplier: 1.0, constant: 0).isActive = true
NSLayoutConstraint(item: demoView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0).isActive = true
}
Installing Boto depends on the Operating system. For e.g in Ubuntu you can use the aptitude command:
sudo apt-get install python-boto
Or you can download the boto code from their site and move into the unzipped directory to run
python setup.py install
What about this regex: \\[^\\]+$
If you would like to have live reload you can use gulp-webserver, which will watch for your file changes and reload page, this way you don't have to press F5 every time on your page:
Here is how to do it:
Open command prompt (cmd) and type
npm install --save-dev gulp-webserver
Enter Ctrl+Shift+P in VS Code and type Configure Task Runner. Select it and press enter. It will open tasks.json file for you. Remove everything from it end enter just following code
tasks.json
{
"version": "0.1.0",
"command": "gulp",
"isShellCommand": true,
"args": [
"--no-color"
],
"tasks": [
{
"taskName": "webserver",
"isBuildCommand": true,
"showOutput": "always"
}
]
}
gulpfile.js
var gulp = require('gulp'),
webserver = require('gulp-webserver');
gulp.task('webserver', function () {
gulp.src('app')
.pipe(webserver({
livereload: true,
open: true
}));
});
Your webserver now will open your page in your default browser. Now any changes that you will do to your HTML or CSS pages will be automatically reloaded.
Here is an information on how to configure 'gulp-webserver' for instance port, and what page to load, ...
You can also run your task just by entering Ctrl+P and type task webserver
PYTHONPATH is an environment variable whose value is a list of directories. Once set, it is used by Python to search for imported modules, along with other std. and 3rd-party library directories listed in Python's "sys.path".
As any other environment variables, you can either export it in shell or in ~/.bashrc, see here. You can query os.environ['PYTHONPATH'] for its value in Python as shown below:
$ python3 -c "import os, sys; print(os.environ['PYTHONPATH']); print(sys.path) if 'PYTHONPATH' in sorted(os.environ) else print('PYTHONPATH is not defined')"
IF defined in shell as
$ export PYTHONPATH=$HOME/Documents/DjangoTutorial/mysite
THEN result =>
/home/Documents/DjangoTutorial/mysite
['', '/home/Documents/DjangoTutorial/mysite', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']
ELSE result =>
PYTHONPATH is not defined
To set PYTHONPATH to multiple paths, see here.
Note that one can add or delete a search path via sys.path.insert(), del or remove() at run-time, but NOT through os.environ[]. Example:
>>> os.environ['PYTHONPATH']="$HOME/Documents/DjangoTutorial/mysite"
>>> 'PYTHONPATH' in sorted(os.environ)
True
>>> sys.path // but Not there
['', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']
>>> sys.path.insert(0,os.environ['PYTHONPATH'])
>>> sys.path // It's there
['$HOME/Documents/DjangoTutorial/mysite', '', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']
>>>
In summary, PYTHONPATH is one way of specifying the Python search path(s) for imported modules in sys.path. You can also apply list operations directly to sys.path without the aid of PYTHONPATH.

The problem is that .form-control
class renders like a DIV
element which according to the normal-flow-of-the-page
renders on a new line.
One way of fixing issues like this is to use display:inline
property. So, create a custom CSS
class with display:inline
and attach it to your component with a .form-control
class. You have to have a width
for your component as well.
There are other ways of handling this issue (like arranging your form-control
components inside any of the .col
classes), but the easiest way is to just make your .form-control
an inline
element (the way a span
would render)
Without a loop, just for the kicks of it...
You can either convert the array to a non-associative one, by doing:
$page = array_values($page);
And then acessing each element by it's zero-based index:
echo $page[0]; // 'index.html'
echo $page[1]; // 'services.html'
Or you can use a slightly more complicated version:
$value = array_slice($page, 0, 1);
echo key($value); // Home
echo current($value); // index.html
$value = array_slice($page, 1, 1);
echo key($value); // Service
echo current($value); // services.html
Spring dependency inject help you to remove coupling from your classes. Instead of creating object like this:
UserService userService = new UserServiceImpl();
You will be using this after introducing DI:
@Autowired
private UserService userService;
For achieving this you need to create a bean of your service in your ServiceConfiguration
file. After that you need to import that ServiceConfiguration
class to your WebApplicationConfiguration
class so that you can autowire that bean into your Controller like this:
public class AccController {
@Autowired
private UserService userService;
}
You can find a java configuration based POC here example.
If you want to change the range to [0, 1], make sure the output data type is float
.
image = cv2.imread("lenacolor512.tiff", cv2.IMREAD_COLOR) # uint8 image
norm_image = cv2.normalize(image, None, alpha=0, beta=1, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_32F)
In the solution below I used python3.4
as binary, but it's safe to use with any version or binary of python. it works fine on windows too (except the downloading pip with wget
obviously but just save the file locally and run it with python).
This is great if you have multiple versions of python installed, so you can manage external libraries per python version.
So first, I'd recommend get-pip.py
, it's great to install pip :
wget https://bootstrap.pypa.io/get-pip.py
Then you need to install pip for your version of python, I have python3.4
so for me this is the command :
python3.4 get-pip.py
Now pip is installed for python3.4
and in order to get libraries for python3.4
one need to call it within this version, like this :
python3.4 -m pip
So if you want to install numpy you would use :
python3.4 -m pip install numpy
Note that numpy
is quite the heavy library. I thought my system was hanging and failing.
But using the verbose option, you can see that the system is fine :
python3.4 -m pip install numpy -v
This may tell you that you lack python.h but you can easily get it :
On RHEL (Red hat, CentOS, Fedora) it would be something like this :
yum install python34-devel
On debian-like (Debian, Ubuntu, Kali, ...) :
apt-get install python34-dev
Then rerun this :
python3.4 -m pip install numpy -v
You can also type "top" and look at the list of running processes.
In Kotlin Android EditText listener is set using,
val searchTo : EditText = findViewById(R.id.searchTo)
searchTo.addTextChangedListener(object : TextWatcher {
override fun afterTextChanged(s: Editable) {
// you can call or do what you want with your EditText here
// yourEditText...
}
override fun beforeTextChanged(s: CharSequence, start: Int, count: Int, after: Int) {}
override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) {}
})
Works and is simpler than every other solution I see here :
Pump().getPumps()
This is great if you don't need to reuse a class instance. Tested on Python 3.7.3.

As said before, you code will not work the way it is. A solution to that would be using a callback function, but if you think it would carry you to a 'Callback hell', you can search for "Promisses".
A possible solution using a callback function:
//DECLARE numberofDocs OUT OF FUNCTIONS
var numberofDocs;
userModel.count({}, setNumberofDocuments); //this search all DOcuments in a Collection
if you want to search the number of documents based on a query, you can do this:
userModel.count({yourQueryGoesHere}, setNumberofDocuments);
setNumberofDocuments is a separeted function :
var setNumberofDocuments = function(err, count){
if(err) return handleError(err);
numberofDocs = count;
};
Now you can get the number of Documents anywhere with a getFunction:
function getNumberofDocs(){
return numberofDocs;
}
var number = getNumberofDocs();
In addition , you use this asynchronous function inside a synchronous one by using a callback, example:
function calculateNumberOfDoc(someParameter, setNumberofDocuments){
userModel.count({}, setNumberofDocuments); //this search all DOcuments in a Collection
setNumberofDocuments(true);
}
Hope it can help others. :)
declare it "static" like this:
static void MyClass::printInformation() { return; }
A for each loop structure is more designed around the collection object. A For..Each loop requires a variant type or object. Since your "element" variable is being typed as a variant your "do_something" function will need to accept a variant type, or you can modify your loop to something like this:
Public Sub Example()
Dim sArray(4) As String
Dim i As Long
For i = LBound(sArray) To UBound(sArray)
do_something sArray(i)
Next i
End Sub

To link to a YouTube video so it plays in HD by default, use the following URL:
https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080
Change VIDEOID to the YouTube video ID that you want to link to. When someone follows the link, it will display the highest-resolution available (up to 1080p) in full-screen mode. Unfortunately, vq=hd1080 does not work on the normal YouTube site (with comments and related videos).
I would check datatypes.
current_date has "date" datatype, 10 is a number, and Table.date - you need to look at your table.
Bootstrap-theme.css is the additional CSS file, which is optional for you to use. It gives 3D effects on the buttons and some other elements.
With Python < 3 (e.g. 2.6 [see comments] or 2.7), there are two ways to do so.
# Option one
older_method_string = "%.9f" % numvar
# Option two
newer_method_string = "{:.9f}".format(numvar)
But note that for Python versions above 3 (e.g. 3.2 or 3.3), option two is preferred.
For more information on option two, I suggest this link on string formatting from the Python documentation.
And for more information on option one, this link will suffice and has info on the various flags.
Python 3.6 (officially released in December of 2016), added the f
string literal, see more information here, which extends the str.format
method (use of curly braces such that f"{numvar:.9f}"
solves the original problem), that is,
# Option 3 (versions 3.6 and higher)
newest_method_string = f"{numvar:.9f}"
solves the problem. Check out @Or-Duan's answer for more info, but this method is fast.
You simply need to make cab
a string:
cab = '6176'
As the error message states, you cannot do <int> in <string>
:
>>> 1 in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>>
because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").
In fact, Python only allows you to use the in
operator with a right operand of type string if the left operand is also of type string:
>>> '1' in '123' # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Well, nothing I used worked, so I decided creating a real simple split function, hope it helps:
DECLARE inipos INTEGER;
DECLARE endpos INTEGER;
DECLARE maxlen INTEGER;
DECLARE item VARCHAR(100);
DECLARE delim VARCHAR(1);
SET delim = '|';
SET inipos = 1;
SET fullstr = CONCAT(fullstr, delim);
SET maxlen = LENGTH(fullstr);
REPEAT
SET endpos = LOCATE(delim, fullstr, inipos);
SET item = SUBSTR(fullstr, inipos, endpos - inipos);
IF item <> '' AND item IS NOT NULL THEN
USE_THE_ITEM_STRING;
END IF;
SET inipos = endpos + 1;
UNTIL inipos >= maxlen END REPEAT;
if(isset($_GET['id']))
{
// Do something
}
You want something like that

There's no pretty way. You might be able to use a proxy with the handler having the target methods and delegating everything else to them. Of course you'll have to use a factory because there'll be no constructor.
I recently just ran into this issue as well. I had a very large table in the dialog div. It was >15,000 rows. When the .empty() was called on the dialog div, I was getting the error above.
I found a round-about solution where before I call cleaning the dialog box, I would remove every other row from the very large table, then call the .empty(). It seemed to have worked though. It seems that my old version of JQuery can't handle such large elements.
The problems were:
The solution based on omerkirk's answer involves:

Quoting the spec
Array objects give special treatment to a certain class of property names. A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1. A property whose property name is an array index is also called an element. Every Array object has a length property whose value is always a nonnegative integer less than 2^32. The value of the length property is numerically greater than the name of every property whose name is an array index; whenever a property of an Array object is created or changed, other properties are adjusted as necessary to maintain this invariant. Specifically, whenever a property is added whose name is an array index, the length property is changed, if necessary, to be one more than the numeric value of that array index; and whenever the length property is changed, every property whose name is an array index whose value is not smaller than the new length is automatically deleted. This constraint applies only to own properties of an Array object and is unaffected by length or array index properties that may be inherited from its prototypes.
And here's a table for typeof
To add some background, there are two data types in JavaScript:
An object in JavaScript is similar in structure to the associative array/dictionary seen in most object oriented languages - i.e., it has a set of key-value pairs.
An array can be considered to be an object with the following properties/keys:
Hope this helped shed more light on why typeof Array returns an object. Cheers!
In my case, I got the image URL before getting to the display component and want to use it as the background image so to use that URL I have to tell Angular that it's safe and can be used.
In .ts file
userImage: SafeStyle;
ngOnInit(){
this.userImage = this.sanitizer.bypassSecurityTrustStyle('url(' + sessionStorage.getItem("IMAGE") + ')');
}
In .html file
<div mat-card-avatar class="nav-header-image" [style.background-image]="userImage"></div>
You've already stated why np.maximum
is different - it returns an array that is the element-wise maximum between two arrays.
As for np.amax
and np.max
: they both call the same function - np.max
is just an alias for np.amax
, and they compute the maximum of all elements in an array, or along an axis of an array.
In [1]: import numpy as np
In [2]: np.amax
Out[2]: <function numpy.core.fromnumeric.amax>
In [3]: np.max
Out[3]: <function numpy.core.fromnumeric.amax>
It is very sad that it is about 2020 still express hasn't added a way to render an HTML page without using sendFile
method of the response
object. Using sendFile
is not a problem but passing argument to it in the form of path.join(__dirname, 'relative/path/to/file')
doesn't feel right. Why should a user join __dirname
to the file path? It should be done by default. Why can't the root of the server be by defalut the project directory? Also, installing a templating dependency just to render a static HTML file is again not correct. I don't know the correct way to tackle the issue, but if I had to serve a static HTML, then I would do something like:
const PORT = 8154;
const express = require('express');
const app = express();
app.use(express.static('views'));
app.listen(PORT, () => {
console.log(`Server is listening at port http://localhost:${PORT}`);
});
The above example assumes that the project structure has a views
directory and the static HTML files are inside it. For example, let's say, the views
directory has two HTML files named index.html
and about.html
, then to access them, we can visit: localhost:8153/index.html
or just localhost:8153/
to load the index.html
page and localhost:8153/about.html
to load the about.html
. We can use a similar approach to serve a react/angular app by storing the artifacts in the views
directory or just using the default dist/<project-name>
directory and configure it in the server js as follows:
app.use(express.static('dist/<project-name>'));
If you look at Twitter's own container-app.html demo on GitHub, you'll get some ideas on using borders with their grid.
For example, here's the extracted part of the building blocks to their 940-pixel wide 16-column grid system:
.row {
zoom: 1;
margin-left: -20px;
}
.row > [class*="span"] {
display: inline;
float: left;
margin-left: 20px;
}
.span4 {
width: 220px;
}
To allow for borders on specific elements, they added embedded CSS to the page that reduces matching classes by enough amount to account for the border(s).
For example, to allow for the left border on the sidebar, they added this CSS in the <head>
after the the main <link href="../bootstrap.css" rel="stylesheet">
.
.content .span4 {
margin-left: 0;
padding-left: 19px;
border-left: 1px solid #eee;
}
You'll see they've reduced padding-left
by 1px
to allow for the addition of the new left border. Since this rule appears later in the source order, it overrides any previous or external declarations.
I'd argue this isn't exactly the most robust or elegant approach, but it illustrates the most basic example.

As Unwind points out f and g provide different default outputs.
Roughly speaking if you care more about the details of what comes after the decimal point I would do with f and if you want to scale for large numbers go with g. From some dusty memories f is very nice with small values if your printing tables of numbers as everything stays lined up but something like g is needed if you stand a change of your numbers getting large and your layout matters. e is more useful when your numbers tend to be very small or very large but never near ten.
An alternative is to specify the output format so that you get the same number of characters representing your number every time.
Sorry for the woolly answer but it is a subjective out put thing that only gets hard answers if the number of characters generated is important or the precision of the represented value.
When you have a copy of an object the [checked]
attribute might not work, in that case, you can use (change)
in this way:
<input type="checkbox" [checked]="item.selected" (change)="item.selected = !item.selected">
display: none;
_x000D_
This should make the element disappear and not take up any space.
I added this on my project and it seems to work:
HTMLElement.prototype.prependHtml = function (element) {
const div = document.createElement('div');
div.innerHTML = element;
this.insertBefore(div, this.firstChild);
};
HTMLElement.prototype.appendHtml = function (element) {
const div = document.createElement('div');
div.innerHTML = element;
while (div.children.length > 0) {
this.appendChild(div.children[0]);
}
};
Example:
document.body.prependHtml(`<a href="#">Hello World</a>`);
document.body.appendHtml(`<a href="#">Hello World</a>`);
Based on (dangerouslySetInnerHTML).
It's a prop that does exactly what you want. However they name it to convey that it should be use with caution
The problem is the length of the filenames. The first filename is only 7 chars long, so the tab occurs at char 8 (doing a tab after every 4 characters). However the next filenames are 8 chars long, so the next tab won't be until char 12. And if you had filenames longer than 11 chars, you'd run into the same problem again.
DateTime has a Date property that you can use to isolate the date part. The ToString method also does a good job of only displaying the Date part when the time part is empty.
I used the following instructions to upgrade from Node.js version 0.10.6 to 0.10.21 on a Mac.
Clear NPM's cache:
sudo npm cache clean -f
Install a little helper called 'n'
sudo npm install -g n
Install latest stable Node.js version
sudo n stable
Alternatively pick a specific version and install like this:
sudo n 0.8.20
For production environments you might want to pay attention to version numbering and be picky about odd/even numbers.

Update (June 2017):
This four years old post still receives up-votes so I'm guessing it still works for many people. However, Mr. Walsh himself recommended to update Node.js just using nvm instead.
So here's what you might want to do today:
Find out which version of Node.js you are using:
node --version
Find out which versions of Node.js you may have installed and which one of those you're currently using:
nvm ls
List all versions of Node.js available for installation:
nvm ls-remote
Apparently for Windows the command would be rather like this:
nvm ls available
Assuming you would pick Node.js v8.1.0 for installation you'd type the following to install that version:
nvm install 8.1.0
You are then free to choose between installed versions of Node.js. So if you would need to use an older version like v4.2.0 you would set it as the active version like this:
nvm use 4.2
If I understood you right, you want to copy $var
in a file (if it's a string).
echo $var > $destdir
If you run pub build --mode=debug
the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug
is used.
Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline
I found the existing answers confusing, and took a long time to work out where the problem is. Here's a compilation of everything I found.
When I run my app, I get an error Failed to execute script foo
(if foo.py
is the main file). To troubleshoot this, don't run PyInstaller with --noconsole
(or edit main.spec
to change console=False
=> console=True
). With this, run the executable from a command-line, and you'll see the failure.
The first thing to check is that it's packaging up your extra files correctly. You should add tuples like ('x', 'x')
if you want the folder x
to be included.
After it crashes, don't click OK. If you're on Windows, you can use Search Everything. Look for one of your files (eg. sword.png
). You should find the temporary path where it unpacked the files (eg. C:\Users\ashes999\AppData\Local\Temp\_MEI157682\images\sword.png
). You can browse this directory and make sure it included everything. If you can't find it this way, look for something like main.exe.manifest
(Windows) or python35.dll
(if you're using Python 3.5).
If the installer includes everything, the next likely problem is file I/O: your Python code is looking in the executable's directory, instead of the temp directory, for files.
To fix that, any of the answers on this question work. Personally, I found a mixture of them all to work: change directory conditionally first thing in your main entry-point file, and everything else works as-is:
if hasattr(sys, '_MEIPASS'):
os.chdir(sys._MEIPASS)
json might not be the best choice for on-disk formats; The trouble it has with appending data is a good example of why this might be. Specifically, json objects have a syntax that means the whole object must be read and parsed in order to understand any part of it.
Fortunately, there are lots of other options. A particularly simple one is CSV; which is supported well by python's standard library. The biggest downside is that it only works well for text; it requires additional action on the part of the programmer to convert the values to numbers or other formats, if needed.
Another option which does not have this limitation is to use a sqlite database, which also has built-in support in python. This would probably be a bigger departure from the code you already have, but it more naturally supports the 'modify a little bit' model you are apparently trying to build.
String a = "...";
String b = "...";
int compare = a.compareTo(b);
if (compare < 0) {
//a is smaller
}
else if (compare > 0) {
//a is larger
}
else {
//a is equal to b
}
This problem appear if two software use same port for connecting to the server
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse or your Software.
I believe this will only appear when running the page locally in this particular case, i.e. you should not see this when loading the apge from a web server.
However if you have permission to do so, you could turn off the prompt for Internet Explorer by following Tools (menu) → Internet Options → Security (tab) → Custom Level (button) → and Disable Automatic prompting for ActiveX controls.
This will of course, only affect your browser.

SOLUTION: (Notice: this solution is for datatables version 1.10.4 (at the moment) not legacy version).
CLARIFICATION Per the API documentation (1.10.15), the API can be accessed three ways:
The modern definition of DataTables (upper camel case):
var datatable = $( selector ).DataTable();
The legacy definition of DataTables (lower camel case):
var datatable = $( selector ).dataTable().api();
Using the new
syntax.
var datatable = new $.fn.dataTable.Api( selector );
Then load the data like so:
$.get('myUrl', function(newDataArray) {
datatable.clear();
datatable.rows.add(newDataArray);
datatable.draw();
});
Use draw(false)
to stay on the same page after the data update.

Importing large sql file to MySql via command line

Here is a universal solution that iterates through every field in form and creates the request string automatically. It is using new fetch API. Automatically reads form attributes: method
and action
and grabs all fields inside the form. Support single-dimension array fields, like emails[]
. Could serve as universal solution to manage easily many (perhaps dynamic) forms with single source of truth - html.
document.querySelector('.ajax-form').addEventListener('submit', function(e) {
e.preventDefault();
let formData = new FormData(this);
let parsedData = {};
for(let name of formData) {
if (typeof(parsedData[name[0]]) == "undefined") {
let tempdata = formData.getAll(name[0]);
if (tempdata.length > 1) {
parsedData[name[0]] = tempdata;
} else {
parsedData[name[0]] = tempdata[0];
}
}
}
let options = {};
switch (this.method.toLowerCase()) {
case 'post':
options.body = JSON.stringify(parsedData);
case 'get':
options.method = this.method;
options.headers = {'Content-Type': 'application/json'};
break;
}
fetch(this.action, options).then(r => r.json()).then(data => {
console.log(data);
});
});
<form method="POST" action="some/url">
<input name="emails[]">
<input name="emails[]">
<input name="emails[]">
<input name="name">
<input name="phone">
</form>
Ideally, you should not need to use globals. The fragment has different notifications, one of them being onActivityCreated. You can get the instance of the activity in this lifecycle event of the fragment.
Then: you can dereference the fragment to get activity, context or applicationcontext as you desire:
this.getActivity()
will give you the handle to the activity
this.getContext()
will give you a handle to the context
this.getActivity().getApplicationContext()
will give you the handle to the application context. You should preferably use the application context when passing it on to the db.
You are making an ajax request which is asynchronous therefore your console log of the list length occurs before the ajax request has completed.
The only way of achieving what you want is changing the ajax call to be synchronous. You can do this by using the .ajax and passing in asynch : false however this is not recommended as it locks the UI up until the call has returned, if it fails to return the user has to crash out of the browser.
Just a note to the answer done by James Sulak.
If you want to take into consideration that the node may not exist and want to keep it purely XPATH, then try the following that will return 0 if the node does not exist.
count(a/b[.='tsr']/preceding-sibling::*)+number(boolean(a/b[.='tsr']))
Firstly install ffmpeg-php
project (http://ffmpeg-php.sourceforge.net/)
And then you can use of this simple code:
<?php
$frame = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';
$mov = new ffmpeg_movie($movie);
$frame = $mov->getFrame($frame);
if ($frame) {
$gd_image = $frame->toGDImage();
if ($gd_image) {
imagepng($gd_image, $thumbnail);
imagedestroy($gd_image);
echo '<img src="'.$thumbnail.'">';
}
}
?>
Description: This project use binary extension .so
file, It's very old and last update was for 2008. So, maybe don't works with newer version of FFMpeg
or PHP
.
Firstly install PHP-FFMpeg
project (https://github.com/PHP-FFMpeg/PHP-FFMpeg)
(just run for install: composer require php-ffmpeg/php-ffmpeg
)
And then you can use of this simple code:
<?php
require 'vendor/autoload.php';
$sec = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';
$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);
echo '<img src="'.$thumbnail.'">';
Description: It's newer and more modern project and works with latest version of FFMpeg
and PHP
. Note that it's required to proc_open()
PHP function.
The setTimeout()
function is non-blocking and will return immediately. Therefore your loop will iterate very quickly and it will initiate 3-second timeout triggers one after the other in quick succession. That is why your first alerts pops up after 3 seconds, and all the rest follow in succession without any delay.
You may want to use something like this instead:
var i = 1; // set your counter to 1_x000D_
_x000D_
function myLoop() { // create a loop function_x000D_
setTimeout(function() { // call a 3s setTimeout when the loop is called_x000D_
console.log('hello'); // your code here_x000D_
i++; // increment the counter_x000D_
if (i < 10) { // if the counter < 10, call the loop function_x000D_
myLoop(); // .. again which will trigger another _x000D_
} // .. setTimeout()_x000D_
}, 3000)_x000D_
}_x000D_
_x000D_
myLoop(); // start the loop
_x000D_
You could also neaten it up, by using a self invoking function, passing the number of iterations as an argument:
(function myLoop(i) {_x000D_
setTimeout(function() {_x000D_
console.log('hello'); // your code here _x000D_
if (--i) myLoop(i); // decrement i and call myLoop again if i > 0_x000D_
}, 3000)_x000D_
})(10); // pass the number of iterations as an argument
_x000D_
public byte[] longToBytes(long x) {
ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
buffer.putLong(x);
return buffer.array();
}
public long bytesToLong(byte[] bytes) {
ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
buffer.put(bytes);
buffer.flip();//need flip
return buffer.getLong();
}
Or wrapped in a class to avoid repeatedly creating ByteBuffers:
public class ByteUtils {
private static ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
public static byte[] longToBytes(long x) {
buffer.putLong(0, x);
return buffer.array();
}
public static long bytesToLong(byte[] bytes) {
buffer.put(bytes, 0, bytes.length);
buffer.flip();//need flip
return buffer.getLong();
}
}
Since this is getting so popular, I just want to mention that I think you're better off using a library like Guava in the vast majority of cases. And if you have some strange opposition to libraries, you should probably consider this answer first for native java solutions. I think the main thing my answer really has going for it is that you don't have to worry about the endian-ness of the system yourself.
In my case, I had not given my <input>
elements any ID, and was using a class to apply the datepicker as in SeanJA's answer, but the datepicker was only being applied to the first one. I discovered that JQuery was automatically adding an ID and it was the same one in all of the elements, which explained why only the first was getting datepickered.
Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)
No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.
Not a Java guy, but in JS and other languages I use it's "Not a Number", meaning some operation caused it to become not a valid number.

}
This will work in .NET 4.7.2 with Visual Studio 2017 (15.9.4):
You can pip install pickle by running command pip install pickle-mixin
.
Proceed to import it using import pickle
.
This can be then used normally.

Looking at :help tabs it doesn't look like vim wants to work the way you do...
Buffers are shared across tabs, so it doesn't seem possible to lock a given buffer to appear only on a certain tab.
It's a good idea, though.
You could probably get the effect you want by using a terminal that supports tabs, like multi-gnome-terminal, then running vim instances in each terminal tab. Not perfect, though...

For the reference, in case someone else encounter the same issue, I was stuck during a good hour with this error which should not happen since I was using the NOPASSWD parameter.
What I did NOT know was that sudo may raise the exact same error message when there is no tty and the command the user try to launch is not part of the allowed command in the /etc/sudoers file.
Here a simplified example of my file content with my issue:
bguser ALL = NOPASSWD: \
command_a arg_a, \
command_b arg_b \
command_c arg_c
When bguser will try to launch "sudo command_b arg_b" without any tty (bguser being used for some daemon), then he will encounter the error "no tty present and no askpass program specified".
Why?
Because a comma is missing at the end of line in the /etc/sudoers file...
(I even wonder if this is an expected behavior and not a bug in sudo since the correct error message for such case shoud be "Sorry, user bguser is not allowed to execute etc.")
This works for me (Excel 2013):
Public Sub StartExeWithArgument()
Dim strProgramName As String
Dim strArgument As String
strProgramName = "C:\Program Files\Test\foobar.exe"
strArgument = "/G"
Call Shell("""" & strProgramName & """ """ & strArgument & """", vbNormalFocus)
End Sub
With inspiration from here https://stackoverflow.com/a/3448682.
It might be easier to use JavaScript or jquery for this. Assuming that the height of the header and the footer is 200 then the code will be:
function SetHeight(){
var h = $(window).height();
$("#inner-right").height(h-200);
}
$(document).ready(SetHeight);
$(window).resize(SetHeight);
The GNU guys REALLY messed up when they introduced recursive file searching to grep. grep is for finding REs in files and printing the matching line (g/re/p remember?) NOT for finding files. There's a perfectly good tool with a very obvious name for FINDing files. Whatever happened to the UNIX mantra of do one thing and do it well?
Anyway, here's how you'd do what you want using the traditional UNIX approach (untested):
find /path/to/folder -type f -print |
while IFS= read -r file
do
awk -v old="$oldstring" -v new="$newstring" '
BEGIN{ rlength = length(old) }
rstart = index($0,old) { $0 = substr($0,rstart-1) new substr($0,rstart+rlength) }
{ print }
' "$file" > tmp &&
mv tmp "$file"
done
Not that by using awk/index() instead of sed and grep you avoid the need to escape all of the RE metacharacters that might appear in either your old or your new string plus figure out a character to use as your sed delimiter that can't appear in your old or new strings, and that you don't need to run grep since the replacement will only occur for files that do contain the string you want. Having said all of that, if you don't want the file timestamp to change if you don't modify the file, then just do a diff on tmp and the original file before doing the mv or throw in an fgrep -q before the awk.
Caveat: The above won't work for file names that contain newlines. If you have those then let us know and we can show you how to handle them.
I had the same issue and I fixed it this way:

What's typically meant by 32-bit or 64-bit machine is the size of the externally visible ("architected") general-purpose integer registers.
This has very little to do with how the hardware is built though. For example, let's consider the (long obsolete) Intel Pentium Pro. It's normally considered a "32-bit" processor, even though it supports up to 36-bit physical addresses, has a 64-bit wide data bus, and internally computations on all supported operand types are carried out in a single set of registers (which are therefore 80 bits wide, to support the largest floating point type).
At least in the case of Intel processors, even though larger physical addressing has been available for a long time, the largest amount of memory directly visible within the address space of any one process on a 32-bit processor is also limited to 4 gigabytes (32-bit addressing). The 36-bit physical addressing allows addressing up to 64 gigabytes of RAM, but only 4 gigabytes of that can be directly visible at any given time.
The change to 64-bit machines mostly involved changing what was made visible to the user (or to code at the assembly language level). Again, what you see is rarely identical to what's real. For example, most 64-bit code sees pointers/addresses as being 64 bits, but actual processors don't support that large of addresses. Current CPUs support 48-bit virtual addresses, and (at least as far as I've noticed) a maximum of 40 bits of physical addressing. On the other hand, they're designed so in the future, when larger memory becomes practical, they can extend the physical addressing out to 48 bits without affecting software at all. Even when they increase the 48-bit virtual addressing, in a typical case it'll only affect a small amount of the operating system kernel (normal code is unaffected, because it already assumed addresses are 64 bits).
So, no: a 64-bit machine does not really support up to 64 bits of physical addressing, but most typical 64-bit software should remain compatible with a future processor that did support directly addressing that much RAM.

A normal broadcast Intent is not available anymore after is was send and processed by the system. If you use the sendStickyBroadcast(Intent) method, the Intent is sticky, meaning the Intent you are sending stays around after the broadcast is complete.

"hard coding" means putting something into your source code. If you are not hard coding, then you do something like prompting the user for the data, or allow the user to put the data on the command line, or something like that.
So, to hard code the location of the file as being on the C: drive, you would just put the pathname of the file all together in your source code.
Here is an example.
int main()
{
const char *filename = "C:\\myfile.txt";
printf("Filename is: %s\n", filename);
}
The file name is "hard coded" as: C:\myfile.txt
The reason the backslash is doubled is because backslashes are special in C strings.

My two cents:
I had a ton of problems trying to get my CUDA 8.0 installed properly on Windows 7. I had a previous version installed and I wanted to upgrade so I uninstalled it and tried to install CUDA 8.0 (for tensorflow 1.3). The installation failed every single time, I tried to downgrade to CUDA 7.5 and was able to install it but had a ton of problems with tensorflow (similar to the PATH problem described here). Long story short: what worked for me was:
1) Uninstall EVERY NVIDIA component (except the display graphics driver)
2) Download CUDA toolkit 8.0 (and the patch) https://developer.nvidia.com/cuda-downloads
3) Check the CheckSum MD5 (I used MS https://www.microsoft.com/en-ca/download/confirmation.aspx?id=11533 but any would do) to make sure they were OK (it happened several times that the installer was not dowloaded properly because my WiFi router apparently).
4) Run the CUDA toolkit installer as root
5) download the cudnn 8.0 v6 and add its location to the PATH variable https://developer.nvidia.com/rdp/cudnn-download
Hope that helps and saves some headaches...
NOTE: This script helped me a lot to debug the problem! (Thank you mrry) https://gist.github.com/mrry/ee5dbcfdd045fa48a27d56664411d41c

Simple Follow these steps
Expanding a bit on the answers from @Guru and @Ronnis, you can hide the sequence and make it look more like an auto-increment using a trigger, and have a procedure that does the insert for you and returns the generated ID as an out parameter.
create table batch(batchid number,
batchname varchar2(30),
batchtype char(1),
source char(1),
intarea number)
/
create sequence batch_seq start with 1
/
create trigger batch_bi
before insert on batch
for each row
begin
select batch_seq.nextval into :new.batchid from dual;
end;
/
create procedure insert_batch(v_batchname batch.batchname%TYPE,
v_batchtype batch.batchtype%TYPE,
v_source batch.source%TYPE,
v_intarea batch.intarea%TYPE,
v_batchid out batch.batchid%TYPE)
as
begin
insert into batch(batchname, batchtype, source, intarea)
values(v_batchname, v_batchtype, v_source, v_intarea)
returning batchid into v_batchid;
end;
/
You can then call the procedure instead of doing a plain insert, e.g. from an anoymous block:
declare
l_batchid batch.batchid%TYPE;
begin
insert_batch(v_batchname => 'Batch 1',
v_batchtype => 'A',
v_source => 'Z',
v_intarea => 1,
v_batchid => l_batchid);
dbms_output.put_line('Generated id: ' || l_batchid);
insert_batch(v_batchname => 'Batch 99',
v_batchtype => 'B',
v_source => 'Y',
v_intarea => 9,
v_batchid => l_batchid);
dbms_output.put_line('Generated id: ' || l_batchid);
end;
/
Generated id: 1
Generated id: 2
You can make the call without an explicit anonymous block, e.g. from SQL*Plus:
variable l_batchid number;
exec insert_batch('Batch 21', 'C', 'X', 7, :l_batchid);
... and use the bind variable :l_batchid
to refer to the generated value afterwards:
print l_batchid;
insert into some_table values(:l_batch_id, ...);
You can also use sum
, if you give it a start
argument:
>>> list1, list2, list3 = [1,2,3], ['a','b','c'], [7,8,9]
>>> all_lists = sum([list1, list2, list3], [])
>>> all_lists
[1, 2, 3, 'a', 'b', 'c', 7, 8, 9]
This works in general for anything that has the +
operator:
>>> sum([(1,2), (1,), ()], ())
(1, 2, 1)
>>> sum([Counter('123'), Counter('234'), Counter('345')], Counter())
Counter({'1':1, '2':2, '3':3, '4':2, '5':1})
>>> sum([True, True, False], False)
2
With the notable exception of strings:
>>> sum(['123', '345', '567'], '')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: sum() can't sum strings [use ''.join(seq) instead]
Sample problem but I found my solution with brew.
1. Make sure you have the latest Android Studio installed.
2. Confirm from SDK manager that you have the required SDKs installed.
3. (optional)you could have an AVD installed as well.
4. install Homebrew.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
5. Then run brew update to make sure Homebrew is up to date.
brew update
6. Run brew doctor to make sure everything is safe
brew doctor
7. Add Homebrew's location to your $PATH in your .bash_profile or .zshrc file.
export PATH="/usr/local/bin:$PATH"
8. If you don't have Node already installed, add:
brew install node
9. (Optional) To test out your Node and npm install, try installing Grunt (you might be asked to run with sudo)
npm install -g grunt-cli
10. Install Gradle
brew install gradle
Run: cordova run android --device
with you device connected on a Mac and you have gradle working this time.
You need to set the classpath to find your compiled class:
java -cp C:\Users\Matt\workspace\HelloWorld2\bin HelloWorld2
the 0.44 is ok to run,but 0.45 can not,maybe is the version problem i solved this by the following command: rninit init TaxiApp --source [email protected];
With Bootstrap 4 .hidden-*
classes were completely removed (yes, they were replaced by hidden-*-*
but those classes are also gone from v4 alphas).
Starting with v4-beta, you can combine .d-*-none
and .d-*-block
classes to achieve the same result.
visible-* was removed as well; instead of using explicit .visible-*
classes, make the element visible by not hiding it (again, use combinations of .d-none .d-md-block). Here is the working example:
<div class="col d-none d-sm-block">
<span class="vcard">
…
</span>
</div>
<div class="col d-none d-xl-block">
<div class="d-none d-md-block">
…
</div>
<div class="d-none d-sm-block">
…
</div>
</div>
class="hidden-xs"
becomes class="d-none d-sm-block"
(or d-none d-sm-inline-block) ...
<span class="d-none d-sm-inline">hidden-xs</span>
<span class="d-none d-sm-inline-block">hidden-xs</span>
An example of Bootstrap 4 responsive utilities:
<div class="d-none d-sm-block"> hidden-xs
<div class="d-none d-md-block"> visible-md and up (hidden-sm and down)
<div class="d-none d-lg-block"> visible-lg and up (hidden-md and down)
<div class="d-none d-xl-block"> visible-xl </div>
</div>
</div>
</div>
<div class="d-sm-none"> eXtra Small <576px </div>
<div class="d-none d-sm-block d-md-none d-lg-none d-xl-none"> SMall =576px </div>
<div class="d-none d-md-block d-lg-none d-xl-none"> MeDium =768px </div>
<div class="d-none d-lg-block d-xl-none"> LarGe =992px </div>
<div class="d-none d-xl-block"> eXtra Large =1200px </div>
<div class="d-xl-none"> hidden-xl (visible-lg and down)
<div class="d-lg-none d-xl-none"> visible-md and down (hidden-lg and up)
<div class="d-md-none d-lg-none d-xl-none"> visible-sm and down (or hidden-md and up)
<div class="d-sm-none"> visible-xs </div>
</div>
</div>
</div>

module usersTimeouts
There are two main types of timeouts: connection timeouts and read timeouts. A connect timeout occurs if the timeout is hit while your client is attempting to establish a connection to a remote machine (corresponding to the
connect()
call on the socket). A read timeout occurs any time the server is too slow to send back a part of the response.
Note that connection timeouts emit an ETIMEDOUT
error, and read timeouts emit an ECONNRESET
error.
@Jk1's answer is fine, but Mockito also allows for more succinct injection using annotations:
@InjectMocks MyClass myClass; //@InjectMocks automatically instantiates too
@Mock MyInterface myInterface
But regardless of which method you use, the annotations are not being processed (not even your @Mock) unless you somehow call the static MockitoAnnotation.initMocks()
or annotate the class with @RunWith(MockitoJUnitRunner.class)
.

variables which have some problems. There are some use cases on embedded microcontrollers where static
variables make sense but avoid them in most other cases. strtok()
behaves unexpected when more than 1 thread uses it, when it is used in a interrupt or when there are some other circumstances where more than one input is processed between successive calls to strtok()
.
Consider this example:
#include <stdio.h>
#include <string.h>
//Splits the input by the / character and prints the content in between
//the / character. The input string will be changed
void printContent(char *input)
{
char *p = strtok(input, "/");
while(p)
{
printf("%s, ",p);
p = strtok(NULL, "/");
}
}
int main(void)
{
char buffer[] = "abc/def/ghi:ABC/DEF/GHI";
char *p = strtok(buffer, ":");
while(p)
{
printContent(p);
puts(""); //print newline
p = strtok(NULL, ":");
}
return 0;
}
You may expect the output:
abc, def, ghi,
ABC, DEF, GHI,
But you will get
abc, def, ghi,
This is because you call strtok()
in printContent()
resting the internal state of strtok()
generated in main()
. After returning, the content of strtok()
is empty and the next call to strtok()
returns NULL
.
You could use strtok_r()
when you use a POSIX system, this versions does not need static
variables. If your library does not provide strtok_r()
you can write your own version of it. This should not be hard and Stackoverflow is not a coding service, you can write it on your own.
if u wanna use async await try
export const post = async ( link,data ) => {
const option = {
method: 'post',
url: `${URL}${link}`,
validateStatus: function (status) {
return status >= 200 && status < 300; // default
},
data
};
try {
const response = await axios(option);
} catch (error) {
const { response } = error;
const { request, ...errorObject } = response; // take everything but 'request'
console.log(errorObject);
}
For larger s&r tasks it's better and faster to use grep and xargs, so, for example;
grep -rl 'apples' /dir_to_search_under | xargs sed -i 's/apples/oranges/g'
Define tooltip text
<input type="text" id="firstname" name="firstname" tooltipText="Type in your firstname in this box">
Initialize and configure the script
<script type="text/javascript">
var tooltipObj = new DHTMLgoodies_formTooltip();
tooltipObj.setTooltipPosition('right');
tooltipObj.setPageBgColor('#EEE');
tooltipObj.setCloseMessage('Exit');
tooltipObj.initFormFieldTooltip();
</script>
I don't think this can be done using jQuery's animate
function because the background image does not have the necessary CSS properties to do such fading. jQuery can only utilize what the browser makes possible. (jQuery experts, correct me if I'm wrong of course.)
I guess you would have to work around this by not using genuine background-image
s, but div
elements containing the image, positioned using position: absolute
(or fixed
) and z-index
for stacking. You would then animate those div
s.

Similarily, you can set it in windows environment variables. for example, in Win7
Right click Start-->Computer then Properties-->Advanced System Setting --> Advanced -->Environment Variables in the user variables, click classPath, and Edit and add the full path of jars at the end. voila
It is possible to use currentTarget
of the event
.
Example shows how to proceed with form submit. Likewise you could get function from onclick
attribute etc.
$('form').on('submit', function(event) {
event.preventDefault();
// code
event.currentTarget.submit();
});
In my case, I had the following import in my test case:
import org.junit.jupiter.api.Test;
The correct import is:
import org.junit.Test;
Don't just import any old Test type from junit, make sure you pick the correct one.
From command line to view react version, npm view react version
if it is a new repo you've cloned, it may still be empty, in which case:
git push -u origin master
should likely sort it out.
(did in my case. not sure this is the same issue, thought i should post this just incase. might help others.)
You can also try dropping the index column if it is not needed to compare:
print(df1.reset_index(drop=True) == df2.reset_index(drop=True))
I have used this same technique in a unit test like so:
from pandas.util.testing import assert_frame_equal
assert_frame_equal(actual.reset_index(drop=True), expected.reset_index(drop=True))
The views are probably created using the WITH SCHEMABINDING option and this means they are explicitly wired up to prevent such changes. Looks like the schemabinding worked and prevented you from breaking those views, lucky day, heh? Contact your database administrator and ask him to do the change, after it asserts the impact on the database.
From MSDN:
SCHEMABINDING
Binds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the base table or tables cannot be modified in a way that would affect the view definition. The view definition itself must first be modified or dropped to remove dependencies on the table that is to be modified.
I will try to get the answer with one query using CTE and window function rank()
create the tables
create table Students
(student_id int,
Name varchar(255),
details varchar(255));
create table Subject(
Sub_id int,
name varchar(255));
create table marks
(student_id int,
subject_id int,
mark int);
the answer should be a table with the below fields
student_name | subject_name | mark
plan the execution steps
with CTE as (select s.name, sb.name as subject_name, m.mark, rank() over(partition by sb.name order by m.mark desc) as rn
from Students s
join marks m on s.student_id = m.student_id
join subject sb
on sb.Sub_id = m.subject_id)
select name , subject_name, mark
from CTE
where rn = 1
This depends on what content do you have. You need to initialize your requestMessage.Content
property with new HttpContent. For example:
...
// Add request body
if (isPostRequest)
{
requestMessage.Content = new ByteArrayContent(content);
}
...
where content
is your encoded content. You also should include correct Content-type header.
Oh, it can be even nicer (from this answer):
requestMessage.Content = new StringContent("{\"name\":\"John Doe\",\"age\":33}", Encoding.UTF8, "application/json");
You could try qemu, which is what the Android emulator uses. I believe it actually emulates the ARM hardware.
FWIW, here's a lightweight bitmap-cache I coded and have used for a few months. It's not all-the-bells-and-whistles, so read the code before you use it.
/**
* Lightweight cache for Bitmap objects.
*
* There is no thread-safety built into this class.
*
* Note: you may wish to create bitmaps using the application-context, rather than the activity-context.
* I believe the activity-context has a reference to the Activity object.
* So for as long as the bitmap exists, it will have an indirect link to the activity,
* and prevent the garbaage collector from disposing the activity object, leading to memory leaks.
*/

If the table is compressed this will work:
alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);
update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;
update EVAPP_FEES set AMOUNT = null;
alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);
update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;
alter table EVAPP_FEES move nocompress;
alter table EVAPP_FEES drop column AMOUNT_TEMP;
alter table EVAPP_FEES compress;
Use the verbatim keystroke, ^V
(CTRL+V
, C-v
, whatever).
When you type ^V
into the terminal (or in most Unix editors), the following character is taken verbatim. You can use this to type a literal tab character inside a string you are echoing.
Something like the following works:
echo "^V<tab>" # CTRL+V, TAB
Bash docs (q.v., "quoted-insert")
quoted-insert (C-q, C-v) Add the next character that you type to the line verbatim. This is how to insert key sequences like C-q, for example.
side note: according to this, ALT+TAB
should do the same thing, but we've all bound that sequence to window switching so we can't use it
tab-insert (M-TAB) Insert a tab character.
--
Note: you can use this strategy with all sorts of unusual characters. Like a carriage return:
echo "^V^M" # CTRL+V, CTRL+M
This is because carriage return is ASCII 13, and M is the 13th letter of the alphabet, so when you type ^M
, you get the 13th ASCII character. You can see it in action using ls^M
, at an empty prompt, which will insert a carriage return, causing the prompt to act just like you hit return. When these characters are normally interpreted, verbatim gets you get the literal character.
The following command will list the submodules:
git submodule--helper list
The output is something like this:
<mode> <sha1> <stage> <location>
Note: It requires Git 2.7.0 or above.
You can do it this way:
Declare interface:
public interface MyInterface{
public void foo();
}
Let your Activity imlement it:
public class MyActivity extends Activity implements MyInterface{
public void foo(){
//do stuff
}
public onCreate(){
//your code
MyAdapter adapter = new MyAdapter(this); //this will work as your
//MyInterface listener
}
}
Then pass your activity to ListAdater:
public MyAdapter extends BaseAdater{
private MyInterface listener;
public MyAdapter(MyInterface listener){
this.listener = listener;
}
}
And somewhere in adapter, when you need to call that Activity method:
listener.foo();
By definition "A Set is a collection of values, where each value may occur only once." So, if your array has repeated values then only one value among the repeated values will be added to your Set.
var arr = [1, 2, 3];
var set = new Set(arr);
console.log(set); // {1,2,3}
var arr = [1, 2, 1];
var set = new Set(arr);
console.log(set); // {1,2}
So, do not convert to set if you have repeated values in your array.
php.net/mb_detect_encoding
echo mb_detect_encoding($str, "auto");
or
echo mb_detect_encoding($str, "UTF-8, ASCII, ISO-8859-1");
i really don't know what the results are, but i'd suggest you just take some of your feeds with different encodings and try if mb_detect_encoding
works or not.
update
auto is short for "ASCII,JIS,UTF-8,EUC-JP,SJIS". it returns the detected charset, which you can use to convert the string to utf-8 with iconv.
<?php
function convertToUTF8($str) {
$enc = mb_detect_encoding($str);
if ($enc && $enc != 'UTF-8') {
return iconv($enc, 'UTF-8', $str);
} else {
return $str;
}
}
?>
i haven't tested it, so no guarantee. and maybe there's a simpler way.
Try the following (Which does not print -1 at the end now!)
int index = word.indexOf(guess);
while(index >= 0) {
System.out.println(index);
index = word.indexOf(guess, index+1);
}
//to access the enum with its string value you can convert it to object
//then you can convert enum to object with proberty
//for Example :
enum days { "one" =3, "tow", "Three" }
let _days: any = days;
if (_days.one == days.one)
{
alert(_days.one + ' | ' + _days[4]);
}
you can also quote string
''+document.location+''.substring(2,3);
I had major trouble getting this to work in RCx releases of angular2. The Location package has moved, and running location.go() inside constructor() wont work. It needs to be ngOnInit() or later in the lifecycle. Here is some example code:
import {OnInit} from '@angular/core';
import {Location} from '@angular/common';
@Component({
selector: 'example-component',
templateUrl: 'xxx.html'
})
export class ExampleComponent implements OnInit
{
constructor( private location: Location )
{}
ngOnInit()
{
this.location.go( '/example;example_param=917' );
}
}
Here are the angular resources on the matter: https://angular.io/docs/ts/latest/api/common/index/Location-class.html https://angular.io/docs/ts/latest/api/common/index/LocationStrategy-class.html
A simple explanation that made it more clear to me is:
When you deploy your app, modules in dependencies need to be installed or your app won't work. Modules in devDependencies don't need to be installed on the production server since you're not developing on that machine. link
Here is one way to do it, in case it is still useful: I ran this in pyspark shell, Python version 2.7.12 and my Spark install was version 2.0.1.
PS: I guess you meant to use different seeds for the df_1 df_2 and the code below reflects that.
from pyspark.sql.types import FloatType
from pyspark.sql.functions import randn, rand
import pyspark.sql.functions as F
df_1 = sqlContext.range(0, 10)
df_2 = sqlContext.range(11, 20)
df_1 = df_1.select("id", rand(seed=10).alias("uniform"), randn(seed=27).alias("normal"))
df_2 = df_2.select("id", rand(seed=11).alias("uniform"), randn(seed=28).alias("normal_2"))
def get_uniform(df1_uniform, df2_uniform):
if df1_uniform:
return df1_uniform
if df2_uniform:
return df2_uniform
u_get_uniform = F.udf(get_uniform, FloatType())
df_3 = df_1.join(df_2, on = "id", how = 'outer').select("id", u_get_uniform(df_1["uniform"], df_2["uniform"]).alias("uniform"), "normal", "normal_2").orderBy(F.col("id"))
Here are the outputs I get:

TL;DR: List.stream().forEach()
was the fastest.
I felt I should add my results from benchmarking iteration. I took a very simple approach (no benchmarking frameworks) and benchmarked 5 different methods:
for
List.forEach()
List.stream().forEach()
List.parallelStream().forEach
private List<Integer> list;
private final int size = 1_000_000;
public MyClass(){
list = new ArrayList<>();
Random rand = new Random();
for (int i = 0; i < size; ++i) {
list.add(rand.nextInt(size * 50));
}
}
private void doIt(Integer i) {
i *= 2; //so it won't get JITed out
}
The list in this class shall be iterated over and have some doIt(Integer i)
applied to all it's members, each time via a different method.
in the Main class I run the tested method three times to warm up the JVM. I then run the test method 1000 times summing the time it takes for each iteration method (using System.nanoTime()
). After that's done i divide that sum by 1000 and that's the result, average time.
example:
myClass.fored();
myClass.fored();
myClass.fored();
for (int i = 0; i < reps; ++i) {
begin = System.nanoTime();
myClass.fored();
end = System.nanoTime();
nanoSum += end - begin;
}
System.out.println(nanoSum / reps);
I ran this on a i5 4 core CPU, with java version 1.8.0_05
for
for(int i = 0, l = list.size(); i < l; ++i) {
doIt(list.get(i));
}
execution time: 4.21 ms
for(Integer i : list) {
doIt(i);
}
execution time: 5.95 ms
List.forEach()
list.forEach((i) -> doIt(i));
execution time: 3.11 ms
List.stream().forEach()
list.stream().forEach((i) -> doIt(i));
execution time: 2.79 ms
List.parallelStream().forEach
list.parallelStream().forEach((i) -> doIt(i));
execution time: 3.6 ms
function check (list){
var foundRepeatingValue = false;
var newList = [];
for(i=0;i<list.length;i++){
var thisValue = list[i];
if(i>0){
if(newList.indexOf(thisValue)>-1){
foundRepeatingValue = true;
console.log("getting repeated");
return true;
}
} newList.push(thisValue);
} return false;
}
var list1 = ["dse","dfg","dse"];
check(list1);
Output:
getting repeated
true
You can also try this
Private Declare Function GetWindowText Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal lpString As StringBuilder, ByVal cch As Integer) As Integer
I always use Declare Function instead of DllImport... Its more simply, its shorter and does the same
I keep thinking there must be a better idiom, but for subtraction of columns by name, I tend to do the following:
df <- data.frame(a=1:10, b=1:10, c=1:10, d=1:10)
# return everything except a and c
df <- df[,-match(c("a","c"),names(df))]
df
You can do like below to achieve your result:
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
....
....
#use filter with plot
#or
fg=sns.factorplot('Retailer country', data=df1[(df1['Retailer country']=='United States') | (df1['Retailer country']=='France')], kind='count')
fg.set_xlabels('Retailer country')
plt.show()
#also
#and
fg=sns.factorplot('Retailer country', data=df1[(df1['Retailer country']=='United States') & (df1['Year']=='2013')], kind='count')
fg.set_xlabels('Retailer country')
plt.show()
When you use angle brackets, the compiler searches for the file in the include path list. When you use double quotes, it first searches the current directory (i.e. the directory where the module being compiled is) and only then it'll search the include path list.
So, by convention, you use the angle brackets for standard includes and the double quotes for everything else. This ensures that in the (not recommended) case in which you have a local header with the same name as a standard header, the right one will be chosen in each case.

These assemblies are available as NuGet packages, which is much easier than my original answer.
You can install by either right clicking on References in your project and selecting Manage NuGet packages... and searching for one of the packages listed below, or install using the Package Manager Console:
PM> Install-Package Microsoft.Office.Interop.Excel
These are available as "Primary Interop Assemblies", which can be installed with Office, or downloaded and installed separately. How to: Install Office Primary Interop Assemblies.
Once those are installed, you can reference them in your project in the Add Reference dialog, under .NET. If you do not see those Microsoft.Office.Interop assemblies listed, then they have not been installed yet. Install them from your setup, or download and install them separately (see my link above for the downloads).
If you are using Chrome with Bootstrap Css the classes that control the grid layout eg col-xs-12 etc use "float: left" which, as others have pointed out, wrecks the page breaks. Remove these from your page for printing. It worked for me. (On Chrome version = 49.0.2623.87)
If you really want to use regex, then
>>> df.replace('(^\s+|\s+$)', '', regex=True, inplace=True)
>>> df

But it should be faster to do it like this:
>>> df[0] = df[0].str.strip()

An IEnumerator
is a thing that can enumerate: it has the Current
property and the MoveNext
and Reset
methods (which in .NET code you probably won't call explicitly, though you could).
An IEnumerable
is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator
.
Which do you use? The only reason to use IEnumerator
is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator
. But you'd still need to return that IEnumerator
in an IEnumerable
class.
For a look at what an enumerator (implementing IEnumerator<T>
) looks like, see any Enumerator<T>
class, such as the ones contained in List<T>
, Queue<T>,
or Stack<T>
. For a look at a class implementing IEnumerable
, see any standard collection class.
A layman definition for inflation might be to convert the XML code to Java code. Just a way to understand, e.g., if we have a tag in XML, OS has to create a corresponding Java object in memory, so inflatter reads the XMLtags, and creates the corresponding objects in Java.
AFAIK, the only way to do this is with <canvas/>
...
DEMO V2: http://jsfiddle.net/xLF38/818/
Note, this will only work with images on the same domain and in browsers that support HTML5 canvas:
function getAverageRGB(imgEl) {
var blockSize = 5, // only visit every 5 pixels
defaultRGB = {r:0,g:0,b:0}, // for non-supporting envs
canvas = document.createElement('canvas'),
context = canvas.getContext && canvas.getContext('2d'),
data, width, height,
i = -4,
length,
rgb = {r:0,g:0,b:0},
count = 0;
if (!context) {
return defaultRGB;
}
height = canvas.height = imgEl.naturalHeight || imgEl.offsetHeight || imgEl.height;
width = canvas.width = imgEl.naturalWidth || imgEl.offsetWidth || imgEl.width;
context.drawImage(imgEl, 0, 0);
try {
data = context.getImageData(0, 0, width, height);
} catch(e) {
/* security error, img on diff domain */
return defaultRGB;
}
length = data.data.length;
while ( (i += blockSize * 4) < length ) {
++count;
rgb.r += data.data[i];
rgb.g += data.data[i+1];
rgb.b += data.data[i+2];
}
// ~~ used to floor values
rgb.r = ~~(rgb.r/count);
rgb.g = ~~(rgb.g/count);
rgb.b = ~~(rgb.b/count);
return rgb;
}
For IE, check out excanvas.
In phpMyAdmin, if you set up a field in your table to auto increment, and then insert a row and set that field's value to 10000, it will continue from there.
Use the keyword super within the overridden method in the child class to use the parent class method. You can only use the keyword within the overridden method though. The example below will help.
public class Parent {
public int add(int m, int n){
return m+n;
}
}
public class Child extends Parent{
public int add(int m,int n,int o){
return super.add(super.add(m, n),0);
}
}
public class SimpleInheritanceTest {
public static void main(String[] a){
Child child = new Child();
child.add(10, 11);
}
}
The add
method in the Child class calls super.add
to reuse the addition logic.
But now it is not working and I contacted our hosting team then they told me to use smtp
Newsflash - it was using SMTP before. They've not provided you with the information you need to solve the problem - or you've not relayed it accurately here.
Its possible that they've disabled the local MTA on the webserver, in which case you'll need to connect the SMTP port on a remote machine. There are lots of toolkits which will do the heavy lifting for you. Personally I like phpmailer because it adds other functionality.
Certainly if they've taken away a facility which was there before and your paying for a service then your provider should be giving you better support than that (there are also lots of programs to drop in in place of a full MTA which would do the job).

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison
Doing either
mystring == yourstring
or
mystring.eql? yourstring
Are equivalent.
Use ByteArrayInputStream
:
InputStream is = new ByteArrayInputStream(decodedBytes);
I made another minimalistic wrapper with only 20 lines of code to allow using it like it should:
localStorage.set('myKey',{a:[1,2,5], b: 'ok'});
localStorage.has('myKey'); // --> true
localStorage.get('myKey'); // --> {a:[1,2,5], b: 'ok'}
localStorage.keys(); // --> ['myKey']
localStorage.remove('myKey');
If you don't care about IE =6, you could use pure CSS ...
.forum:hover { background-color: #380606; }
.forum { color: white; }_x000D_
.forum:hover { background-color: #380606 !important; }_x000D_
/* we use !important here to override specificity. see http://stackoverflow.com/q/5805040/ */_x000D_

#blue { background-color: blue; }

With jQuery, usually it is better to create a specific class for this style:
.forum_hover { background-color: #380606; }
and then apply the class on mouseover, and remove it on mouseout.
$('.forum').hover(function(){$(this).toggleClass('forum_hover');});
$(document).ready(function(){_x000D_
$('.forum').hover(function(){$(this).toggleClass('forum_hover');});_x000D_
});
_x000D_
.forum_hover { background-color: #380606 !important; }_x000D_
_x000D_
.forum { color: white; }_x000D_
#blue { background-color: blue; }

<p class="forum" style="background:green;">Green</p>_x000D_

If you must not modify the class, you could save the original background color in .data()
:
$('.forum').data('bgcolor', '#380606').hover(function(){
var $this = $(this);
var newBgc = $this.data('bgcolor');
$this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);
});
$(document).ready(function(){_x000D_
$('.forum').data('bgcolor', '#380606').hover(function(){_x000D_
var $this = $(this);_x000D_
var newBgc = $this.data('bgcolor');_x000D_
$this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);_x000D_
});_x000D_
});
_x000D_
.forum { color: white; }_x000D_
#blue { background-color: blue; }
_x000D_

or
$('.forum').hover(
function(){
var $this = $(this);
$this.data('bgcolor', $this.css('background-color')).css('background-color', '#380606');
},
function(){

use List<T>
. Internally it uses arrays and arrays do use contiguous memory.
Python does not have a defined entry point like Java, C, C++, etc. Rather it simply executes a source file line-by-line. The if
statement allows you to create a main
function which will be executed if your file is loaded as the "Main" module rather than as a library in another module.
To be clear, this means that the Python interpreter starts at the first line of a file and executes it. Executing lines like class Foobar:
and def foobar()
creates either a class or a function and stores them in memory for later use.
Adding mode:'no-cors'
to the request header guarantees that no response will be available in the response
Adding a "non standard" header, line 'access-control-allow-origin'
will trigger a OPTIONS preflight request, which your server must handle correctly in order for the POST request to even be sent
You're also doing fetch
wrong ... fetch
returns a "promise" for a Response
object which has promise creators for json
, text
, etc. depending on the content type...
In short, if your server side handles CORS correctly (which from your comment suggests it does) the following should work
function send(){
var myVar = {"id" : 1};
console.log("tuleb siia", document.getElementById('saada').value);
fetch("http://localhost:3000", {
method: "POST",
headers: {
"Content-Type": "text/plain"
},
body: JSON.stringify(myVar)
}).then(function(response) {
return response.json();
}).then(function(muutuja){
document.getElementById('väljund').innerHTML = JSON.stringify(muutuja);
});
}
however, since your code isn't really interested in JSON (it stringifies the object after all) - it's simpler to do
function send(){
var myVar = {"id" : 1};
console.log("tuleb siia", document.getElementById('saada').value);
fetch("http://localhost:3000", {
method: "POST",
headers: {
"Content-Type": "text/plain"
},
body: JSON.stringify(myVar)
}).then(function(response) {
return response.text();
}).then(function(muutuja){
document.getElementById('väljund').innerHTML = muutuja;
});
}
