the same problem occurs to me...
I check the file wrx permissions with:
$ls -l ./gradlew
-> -rw-rw-r-- (no execute permission)
so I use command $chmod +x ./gradlew
and this problem solved.
Code written in Java is:
When does java interpret the bytecode and when does it compile it? The application code is initially interpreted, but the JVM monitors which sequences of bytecode are frequently executed and translates them to machine code for direct execution on the hardware. For bytecode which is executed only a few times, this saves the compilation time and reduces the initial latency; for frequently executed bytecode, JIT compilation is used to run at high speed, after an initial phase of slow interpretation. Additionally, since a program spends most time executing a minority of its code, the reduced compilation time is significant. Finally, during the initial code interpretation, execution statistics can be collected before compilation, which helps to perform better optimization.
A C++14 version of the answer provided by R. Martinho Fernandes would be:
#include <type_traits>
template <typename E>
constexpr auto to_underlying(E e) noexcept
{
return static_cast<std::underlying_type_t<E>>(e);
}
As with the previous answer, this will work with any kind of enum and underlying type. I have added the noexcept
keyword as it will never throw an exception.
Update
This also appears in Effective Modern C++ by Scott Meyers. See item 10 (it is detailed in the final pages of the item within my copy of the book).
I would use the translate method without translation table. It deletes the letters in second argument in recent Python versions.
def remove_chars(line):
line7=line[7].translate(None,'abcd')
return line[:7]+[line7]+line[8:]
line= ['ad','da','sdf','asd',
'3424','342sfas','asdfaf','sdfa',
'afase']
print line[7]
line = remove_chars(line)
print line[7]
This really depends on your requirements. First, see if you really need a workflow engine (this or other sources). Unless you really need it, probably you should avoid it.
If you really need what provides a workflow engine, I would pick one that is already built. People who works with jbpm or activiti have much more experience than you in building workflow engines, so it is probably already tunned to improve performance.
Microsoft has a nice chart control. Download it here. Great video on this here. Example code is here. Happy coding!
THe easiest way to do so is:
function findChild(idOfElement, idOfChild){
let element = document.getElementById(idOfElement);
return element.querySelector('[id=' + idOfChild + ']');
}
or better readable:
findChild = (idOfElement, idOfChild) => {
let element = document.getElementById(idOfElement);
return element.querySelector(`[id=${idOfChild}]`);
}
Try this (edited):
ctx.Database.ExecuteSqlCommand(sql, new SqlParameter("FirstName", firstName),
new SqlParameter("Id", id));
Previous idea was wrong.
Use Integer
instead.
HashMap<Integer, MyObject> myMap = new HashMap<Integer, MyObject>();
Java will automatically autobox your int
primitive values to Integer
objects.
Read more about autoboxing from Oracle Java documentations.
Here's how to disable minification on a per-bundle basis:
bundles.Add(new StyleBundleRaw("~/Content/foobarcss").Include("/some/path/foobar.css"));
bundles.Add(new ScriptBundleRaw("~/Bundles/foobarjs").Include("/some/path/foobar.js"));
Sidenote: The paths used for your bundles must not coincide with any actual path in your published builds otherwise nothing will work. Also make sure to avoid using .js, .css and/or '.' and '_' anywhere in the name of the bundle. Keep the name as simple and as straightforward as possible, like in the example above.
The helper classes are shown below. Notice that in order to make these classes future-proof we surgically remove the js/css minifying instances instead of using .clear() and we also insert a mime-type-setter transformation without which production builds are bound to run into trouble especially when it comes to properly handing over css-bundles (firefox and chrome reject css bundles with mime-type set to "text/html" which is the default):
internal sealed class StyleBundleRaw : StyleBundle
{
private static readonly BundleMimeType CssContentMimeType = new BundleMimeType("text/css");
public StyleBundleRaw(string virtualPath) : this(virtualPath, cdnPath: null)
{
}
public StyleBundleRaw(string virtualPath, string cdnPath) : base(virtualPath, cdnPath)
{
Transforms.Add(CssContentMimeType); //0 vital
Transforms.Remove(Transforms.FirstOrDefault(x => x is CssMinify)); //0
}
//0 the guys at redmond in their infinite wisdom plugged the mimetype "text/css" right into cssminify upon unwiring the minifier we
// need to somehow reenable the cssbundle to specify its mimetype otherwise it will advertise itself as html and wont load
}
internal sealed class ScriptBundleRaw : ScriptBundle
{
private static readonly BundleMimeType JsContentMimeType = new BundleMimeType("text/javascript");
public ScriptBundleRaw(string virtualPath) : this(virtualPath, cdnPath: null)
{
}
public ScriptBundleRaw(string virtualPath, string cdnPath) : base(virtualPath, cdnPath)
{
Transforms.Add(JsContentMimeType); //0 vital
Transforms.Remove(Transforms.FirstOrDefault(x => x is JsMinify)); //0
}
//0 the guys at redmond in their infinite wisdom plugged the mimetype "text/javascript" right into jsminify upon unwiring the minifier we need
// to somehow reenable the jsbundle to specify its mimetype otherwise it will advertise itself as html causing it to be become unloadable by the browsers in published production builds
}
internal sealed class BundleMimeType : IBundleTransform
{
private readonly string _mimeType;
public BundleMimeType(string mimeType) { _mimeType = mimeType; }
public void Process(BundleContext context, BundleResponse response)
{
if (context == null)
throw new ArgumentNullException(nameof(context));
if (response == null)
throw new ArgumentNullException(nameof(response));
response.ContentType = _mimeType;
}
}
To make this whole thing work you need to install (via nuget):
WebGrease 1.6.0+ Microsoft.AspNet.Web.Optimization 1.1.3+
And your web.config should be enriched like so:

<!-- setting mimetypes like we do right below is absolutely vital for published builds because for some reason the -->

Note that you might have to take extra steps to make your css-bundles work in terms of fonts etc. But that's a different story.

If spring-security
jars are added in classpath and also if it is spring-boot
application all http endpoints will be secured by default security configuration class SecurityAutoConfiguration
This causes a browser pop-up to ask for credentials.
The password changes for each application restarts and can be found in console.
Using default security password: 78fa095d-3f4c-48b1-ad50-e24c31d5cf35
To add your own layer of application security in front of the defaults,
@EnableWebSecurity
public class SecurityConfig {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}
}
or if you just want to change password you could override default with,
application.xml
security.user.password=new_password
or
application.properties
spring.security.user.name=<>
spring.security.user.password=<>

Connecting to shared virtual machines
Connection to VMware Workstation Server (the shared virtual machines) is administered by the VMware Host Agent service. The service uses TCP ports 80 and 443. This service is also used by other VMware products, including VMware Server and vSphere, and provides additional capabilities. Configuring shared virtual machines
With the Shared VMs Workstation preferences, you can disable/enable the server, assign a different port for connecting, and change the Shared VMs directory.
To access the Shared VMs Workstation preferences:
Go to Edit > Preferences.
Click the Shared VMs tab.
To improve Darin's answer, it can be bit shorter:
public class UniqueFileName : ValidationAttribute
{
private readonly NewsService _newsService = new NewsService();
public override bool IsValid(object value)
{
if (value == null) { return false; }
var file = (HttpPostedFile) value;
return _newsService.IsFileNameUnique(file.FileName);
}
}
Model:
[UniqueFileName(ErrorMessage = "This file name is not unique.")]
Do note that an error message is required, otherwise the error will be empty.
It may be because your web folder (as mentioned "/Applications/MAMP/htdocs/mysite/web") is empty.
My suggestion is first to make your project and then work on making the virtual host.
I went with a similar situation. I was using an empty folder in the DocumentRoot in httpd-vhosts.confiz and I couldn't access my shahg101.com site.
a=input("Enter number:")
def isprime():
total=0
factors=(1,a)# The only factors of a number
pfactors=range(1,a+1) #considering all possible factors
if a==1 or a==0:# One and Zero are not prime numbers
print "%d is NOT prime"%a
elif a==2: # Two is the only even prime number
print "%d is prime"%a
elif a%2==0:#Any even number is not prime except two
print "%d is NOT prime"%a
else:#a number is prime if its multiples are 1 and itself
#The sum of the number that return zero moduli should be equal to the "only" factors
for number in pfactors:
if (a%number)==0:
total+=number
if total!=sum(factors):
print "%d is NOT prime"%a
else:
print "%d is prime"%a
isprime()
i think it's just the debugger making it simple. Note that a case and "if list" are not ultimately the same. There is is a reason why case blocks normally end with "break". The case stmt actually looks something like this when broken down in assembly.
if myObject.GetType() == type of Car
GOTO START_CAR
else if myObject.GetType() == type of Bike
GOTO START_BIKE
LABEL START_CAR
//do something car
GOTO END
LABEL START_BIKE
//do something bike
GOTO END
LABEL END
If you don't have the break, then the case blocks would be missing the "GOTO END" stmts, and in fact if you landed in the "car" case you'd actually run both sections
//do something car
//do something bike
GOTO END
I used convertPoint method to get point from tableview and pass this point to indexPathForRowAtPoint method to get indexPath
@IBAction func newsButtonAction(sender: UIButton) {
let buttonPosition = sender.convertPoint(CGPointZero, toView: self.newsTableView)
let indexPath = self.newsTableView.indexPathForRowAtPoint(buttonPosition)
if indexPath != nil {
if indexPath?.row == 1{
self.performSegueWithIdentifier("alertViewController", sender: self);
}
}
}
You can do this In the parent component declare:
get self(): ParenComponentClass {
return this;
}
In the child component,after include the import of ParenComponentClass, declare:
private _parent: ParenComponentClass ;
@Input() set parent(value: ParenComponentClass ) {
this._parent = value;
}
get parent(): ParenComponentClass {
return this._parent;
}
Then in the template of the parent you can do
<childselector [parent]="self"></childselector>
Now from the child you can access public properties and methods of parent using
this.parent
Simple: [boolean](get-variable "Varname" -ErrorAction SilentlyContinue)
I've run into this issue where I had a file that sets variables based on the GET parameters. And that file could not updated because it worked correctly on another part of a large content management system. Yet I wanted to run that code via an include file without the parameters actually being in the URL string. The simple solution is you can set the GET variables in first file as you would any other variable.
Instead of:
include "myfile.php?var=apple";
It would be:
$_GET['var'] = 'apple';
include "myfile.php";
Resizing images in a canvas element is generally bad idea since it uses the cheapest box interpolation. The resulting image noticeable degrades in quality. I'd recommend using http://nodeca.github.io/pica/demo/ which can perform Lanczos transformation instead. The demo page above shows difference between canvas and Lanczos approaches.
It also uses web workers for resizing images in parallel. There is also WEBGL implementation.
There are some online image resizers that use pica for doing the job, like https://myimageresizer.com
Don't use ix
. It's deprecated. The most readable and idiomatic way of doing this is df.drop()
:
>>> df
a b c d
0 0.175127 0.191051 0.382122 0.869242
1 0.414376 0.300502 0.554819 0.497524
2 0.142878 0.406830 0.314240 0.093132
3 0.337368 0.851783 0.933441 0.949598
>>> df.drop('b', axis=1)
a c d
0 0.175127 0.382122 0.869242
1 0.414376 0.554819 0.497524
2 0.142878 0.314240 0.093132
3 0.337368 0.933441 0.949598
Note that by default, .drop()
does not operate inplace; despite the ominous name, df
is unharmed by this process. If you want to permanently remove b
from df
, do df.drop('b', inplace=True)
.
df.drop()
also accepts a list of labels, e.g. df.drop(['a', 'b'], axis=1)
will drop column a
and b
.
Similar to one of the answers above, but try adding .sort_values()
to your .groupby()
will allow you to change the sort order. If you need to sort on a single column, it would look like this:
df.groupby('group')['id'].count().sort_values(ascending=False)
ascending=False
will sort from high to low, the default is to sort from low to high.
*Careful with some of these aggregations. For example .size() and .count() return different values since .size() counts NaNs.
This is the best solution provided by Google Developers
. Simply call this method in onResume of onCreate after initializing GoogleApiClient
.
private void updateMarkers() {
if (mMap == null) {
return;
}
if (mLocationPermissionGranted) {
// Get the businesses and other points of interest located
// nearest to the device's current location.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).build();
mGoogleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(10000 / 2);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest
.Builder()
.addLocationRequest(mLocationRequest);
PendingResult<LocationSettingsResult> resultPendingResult = LocationServices
.SettingsApi
.checkLocationSettings(mGoogleApiClient, builder.build());
resultPendingResult.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(@NonNull LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
final LocationSettingsStates locationSettingsStates = locationSettingsResult.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can
// initialize location requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied, but this can be fixed
// by showing the user a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
MainActivity.this,
PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way
// to fix the settings so we won't show the dialog.
break;
}
}
});
@SuppressWarnings("MissingPermission")
PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi
.getCurrentPlace(mGoogleApiClient, null);
result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
@Override
public void onResult(@NonNull PlaceLikelihoodBuffer likelyPlaces) {
for (PlaceLikelihood placeLikelihood : likelyPlaces) {
// Add a marker for each place near the device's current location, with an
// info window showing place information.
String attributions = (String) placeLikelihood.getPlace().getAttributions();
String snippet = (String) placeLikelihood.getPlace().getAddress();
if (attributions != null) {
snippet = snippet + "\n" + attributions;
}
mMap.addMarker(new MarkerOptions()
.position(placeLikelihood.getPlace().getLatLng())
.title((String) placeLikelihood.getPlace().getName())
.snippet(snippet));
}
// Release the place likelihood buffer.
likelyPlaces.release();
}
});
} else {
mMap.addMarker(new MarkerOptions()
.position(mDefaultLocation)
.title(getString(R.string.default_info_title))
.snippet(getString(R.string.default_info_snippet)));
}
}
Note : This line of code automatic open the dialog box if Location
is not on. This piece of line is used in Google Map also
status.startResolutionForResult(
MainActivity.this,
PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
You can use stem method to get file name.
Here is an example:
from pathlib import Path
p = Path(r"\\some_directory\subdirectory\my_file.txt")
print(p.stem)
# my_file
pip install django-cors-headers
and then add it to your installed apps:
INSTALLED_APPS = (
...
'corsheaders',
...
)
You will also need to add a middleware class to listen in on responses:
MIDDLEWARE_CLASSES = (
...
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
...
)
CORS_ORIGIN_ALLOW_ALL = True # If this is used then `CORS_ORIGIN_WHITELIST` will not have any effect
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = [
'http://localhost:3030',
] # If this is used, then not need to use `CORS_ORIGIN_ALLOW_ALL = True`
CORS_ORIGIN_REGEX_WHITELIST = [
'http://localhost:3030',
]
more details: https://github.com/ottoyiu/django-cors-headers/#configuration
read the official documentation can resolve almost all problem
In Notepad++, you can use the Mark tab in the Find dialogue to Bookmark all lines matching your query which can be regex or normal (wildcard).
Then use Search > Bookmark > Remove Bookmarked Lines.
From SQL2012, there is a new function introduced called EOMONTH
. Using this function the first and last day of the last month can be easily found.
select DATEADD(DD,1,EOMONTH(Getdate(),-2)) firstdayoflastmonth, EOMONTH(Getdate(), -1) lastdayoflastmonth
Here is an example from the MDN docs itself:
var str = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
var regexp = /[A-E]/gi;
var matches_array = str.match(regexp);
console.log(matches_array);
// ['A', 'B', 'C', 'D', 'E', 'a', 'b', 'c', 'd', 'e']
Quick trick-
SELECT CAST('<A><![CDATA[' + CAST(LogInfo as nvarchar(max)) + ']]></A>' AS xml)
FROM Logs
WHERE IDLog = 904862629
You can do it fast, only using one POSIX function. If you have bunch of tasks with dates, see the module DateTime.
use POSIX qw(strftime);
my $date = strftime "%m/%d/%Y", localtime;
print $date;
Short answer: soup.findAll('p')[0].next
Real answer: You need an invariant reference point from which you can get to your target.
You mention in your comment to Haidro's answer that the text you want is not always in the same place. Find a sense in which it is in the same place relative to some element. Then figure out how to make BeautifulSoup navigate the parse tree following that invariant path.
For example, in the HTML you provide in the original post, the target string appears immediately after the first paragraph element, and that paragraph is not empty. Since findAll('p')
will find paragraph elements, soup.find('p')[0]
will be the first paragraph element.
You could in this case use soup.find('p')
but soup.findAll('p')[n]
is more general since maybe your actual scenario needs the 5th paragraph or something like that.
The next
field attribute will be the next parsed element in the tree, including children. So soup.findAll('p')[0].next
contains the text of the paragraph, and soup.findAll('p')[0].next.next
will return your target in the HTML provided.
I am using the following and it is working fine plus without any third-party dependencies.
const {
randomBytes
} = require('crypto');
const uid = Math.random().toString(36).slice(2) + randomBytes(8).toString('hex') + new Date().getTime();
EDIT :
The implementation of a Singleton in Android is not "safe" (see here) and you should use a library dedicated to this kind of pattern like Dagger or other DI library to manage the lifecycle and the injection.
Could you post an example from your code ?
Take a look at this gist : https://gist.github.com/Akayh/5566992
it works but it was done very quickly :
MyActivity : set the singleton for the first time + initialize mString attribute ("Hello") in private constructor and show the value ("Hello")
Set new value to mString : "Singleton"
Launch activityB and show the mString value. "Singleton" appears...
The app token can be found from this url.
If you are using macOS {mine 'High Sierra'} and Installed XAMPP
You can find mysql data files;
Go to : /Applications/XAMPP/xamppfiles/var/mysql/
I don't know how to do so with built in CMD but if you have grep you can try the following:
tasklist /FI "IMAGENAME eq myApp.exe" | grep myApp.exe
if ERRORLEVEL 1 echo "myApp is not running"
The ioctl
function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl
could be used to get the current font as well as set the font to a new one. A user application uses ioctl
to send a code to a printer telling it to return the current font or to set the font to a new one.
int ioctl(int fd, int request, ...)
fd
is file descriptor, the one returned by open
;request
is request code. e.g GETFONT
will get the current font from the printer, SETFONT
will set the font on the printer;void *
. Depending on the second argument, the third may or may not be present,
e.g. if the second argument is SETFONT
, the third argument can be the font name such as "Arial"
;int request
is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl
and then uses the request code in the device driver module to determine which action to perform.
A request code has 4 main parts
1. A Magic number - 8 bits
2. A sequence number - 8 bits
3. Argument type (typically 14 bits), if any.
4. Direction of data transfer (2 bits).
If the request code is SETFONT
to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial"
to the printer).
If the request code is GETFONT
, direction is from printer to the user application.
In order to generate a request code, Linux provides some predefined function-like macros.
1._IO(MAGIC, SEQ_NO)
both are 8 bits, 0 to 255, e.g. let us say we want to pause printer.
This does not require a data transfer. So we would generate the request code as below
#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM)
and now use ioctl
as
ret_val = ioctl(fd, PAUSE_PRIN);
The corresponding system call in the driver module will receive the code and pause the printer.
__IOW(MAGIC, SEQ_NO, TYPE)
MAGIC
and SEQ_NO
are the same as above, and TYPE
gives the type of the next argument, recall the third argument of ioctl
is void *
. W in __IOW
indicates that the data flow is from user application to driver module. As an example,
suppose we want to set the printer font to "Arial"
.#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)
further,
char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font);
Now font
is a pointer, which means it is an address best represented as unsigned long
, hence the third part of _IOW
mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long
and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE)
and __IORW(MAGIC, SEQ_NO, TYPE)
where the data flow will be from kernel space to user space and both ways respectively.
Please let me know if this helps!
In Laravel Version - 4, HTML and Form existed, but not now.
Why:
The only reason is they have collected some user requirements and they want it more lightweight and so they removed it as in the sense that a user can add it manually.
What to do to add HTML & Forms in Laravel 5.2 or 5.3:
For 5.2:
Go to the Laravel Collective site and installation processes have demonstrated their.
Like for 5.2: on the command line, run the command
composer require "laravelcollective/html":"^5.2.0"
Then, in the provider array which is in config/app.php. Add this line at last using a comma(,):
Collective\Html\HtmlServiceProvider::class,
For using HTML and FORM text we need to alias them in the aliases array of config/app.php. Add the two lines at the last
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
And for 5.3:
Just run the command
composer require "laravelcollective/html":"^5.3.0"
And the rest of the procedure is like 5.2.
Then you can use Laravel Form and other HTML links in your projects. For this, follow this documentation:
5.2: https://laravelcollective.com/docs/5.2/html
5.3: https://laravelcollective.com/docs/5.3/html
Demo Code:
To open a form, open and close a tag:
{!! Form::open(['url' => 'foo/bar']) !!}
{!! Form::close() !!}
And for creating label and input text with a Bootstrap form-control class and other use:
{!! Form::label('title', 'Post Title') !!}
{!! Form::text('title', null, array('class' => 'form-control')) !!}
And for more, use the documentation, https://laravelcollective.com/.

Update: Unless you love resizing icons one by one, check out Schmoudi's answer. It's just a lot easier.
Above image from Designing for iOS 9. They are the same for iOS 10.
Click Assets.xcassets in the Project navigator and then choose AppIcon.
This will give you an empty app icon set.
Now just drag the right sized image (in .png format) from Finder onto every blank in the app set. The app icon should be all set up now.
The image at the very top tells the pixels sizes for for each point size that is required in iOS 9. However, even if I don't get this answer updated for future versions of iOS, you can still figure out the correct pixel sizes using the method below.
Look at how many points (pt) each blank on the empty image set is. If the image is 1x then the pixels are the same as the points. For 2x double the points and 3x triple the points. So, for example, in the first blank above (29pt 2x) you would need a 58x58 pixel image.
You can start with a 1024x1024 pixel image and then downsize it to the correct sizes. You can do it yourself or there are also websites and scripts for getting the right sizes. Do a search for "ios app icon generator" or something similar.
I don't think the names matter as long as you get the dimensions right, but the general naming convention is as follows:
Icon-29.png // 29x29 pixels
[email protected] // 58x58 pixels
[email protected] // 87x87 pixels
Although you can use an image for the launch screen, consider using a launch screen storyboard file. This will conveniently resize for every size and orientation. Check out this SO answer or the following documentation for help with this.
The Xcode images in this post were created with Xcode 7.
You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)
$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property
Or just this, xpath is case sensitive. Both have the same output:
$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml

If your website is using authentication, but you don't have the correct authentication method set up in IIS (e.g. Basic, Forms etc..) then the browser will be getting stuck in a redirect loop. This causes the redirect url to get longer and longer until it explodes.
To get a footer that sticks to the bottom of your viewport, give it a fixed position like this:
footer {
position: fixed;
height: 100px;
bottom: 0;
width: 100%;
}
Bootstrap includes this CSS in the Navbar > Placement section with the class fixed-bottom
. Just add this class to your footer element:
<footer class="fixed-bottom">

It looks as if you could use the API functions to

I guess you're using the DOM Data Source (for server-side processing) to generate your table. I didn't really get that at first, so my previous answer won't work for that.
To get it to work without rewriting your server side code:
What you'll need to do is totally remove the old table (in the dom) and replace it with the ajax result content, then reinitialize the datatable:
// in your $.post callback:
function (data) {
// remove the old table
$("#ajaxresponse").children().remove();
// replace with the new table
$("#ajaxresponse").html(data);
// reinitialize the datatable
$('#rankings').dataTable( {
"sDom":'t<"bottom"filp><"clear">',
"bAutoWidth": false,
"sPaginationType": "full_numbers",
"aoColumns": [
{ "bSortable": false, "sWidth": "10px" },
null,
null,
null,
null,
null,
null,
null,
null,
null,
null,
null
]
}
);
}
In DOS you couldn't use environment variables on the command line, only in batch files, where they used the %
sign as a delimiter. If you wanted a literal %
sign in a batch file, e.g. in an echo
statement, you needed to double it.
This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your %
signs in a .cmd file.

From a SQLServerCentral.Com article by Ken Powers:
The Semicolon
The semicolon character is a statement terminator. It is a part of the ANSI SQL-92 standard, but was never used within Transact-SQL. Indeed, it was possible to code T-SQL for years without ever encountering a semicolon.
Usage
There are two situations in which you must use the semicolon. The first situation is where you use a Common Table Expression (CTE), and the CTE is not the first statement in the batch. The second is where you issue a Service Broker statement and the Service Broker statement is not the first statement in the batch.
If you want to run the command for every line (i.e. result) coming from find
, then what do you need the xargs
for?
Try:
find
path -type f -exec
your-command {} \;
where the literal {}
gets substituted by the filename and the literal \;
is needed for find
to know that the custom command ends there.
(after the edit of your question clarifying that you know about -exec
)
From man xargs
:
-L max-lines
Use at most max-lines nonblank input lines per command line. Trailing blanks cause an input line to be logically continued on the next input line. Implies -x.
Note that filenames ending in blanks would cause you trouble if you use xargs
:
$ mkdir /tmp/bax; cd /tmp/bax
$ touch a\ b c\ c
$ find . -type f -print | xargs -L1 wc -l
0 ./c
0 ./c
0 total
0 ./b
wc: ./a: No such file or directory
So if you don't care about the -exec
option, you better use -print0
and -0
:
$ find . -type f -print0 | xargs -0L1 wc -l
0 ./c
0 ./c
0 ./b
0 ./a
I don't think so.
a.concat(b)
is implemented in String and I think the implementation didn't change much since early java machines. The +
operation implementation depends on Java version and compiler. Currently +
is implemented using StringBuffer
to make the operation as fast as possible. Maybe in the future, this will change. In earlier versions of java +
operation on Strings was much slower as it produced intermediate results.
I guess that +=
is implemented using +
and similarly optimized.
UrlCreateFromPath to the rescue! Well, not entirely, as it doesn't support extended and UNC path formats, but that's not so hard to overcome:
public static Uri FileUrlFromPath(string path)
{
const string prefix = @"\\";
const string extended = @"\\?\";
const string extendedUnc = @"\\?\UNC\";
const string device = @"\\.\";
const StringComparison comp = StringComparison.Ordinal;
if(path.StartsWith(extendedUnc, comp))
{
path = prefix+path.Substring(extendedUnc.Length);
}else if(path.StartsWith(extended, comp))
{
path = prefix+path.Substring(extended.Length);
}else if(path.StartsWith(device, comp))
{
path = prefix+path.Substring(device.Length);
}
int len = 1;
var buffer = new StringBuilder(len);
int result = UrlCreateFromPath(path, buffer, ref len, 0);
if(len == 1) Marshal.ThrowExceptionForHR(result);
buffer.EnsureCapacity(len);
result = UrlCreateFromPath(path, buffer, ref len, 0);
if(result == 1) throw new ArgumentException("Argument is not a valid path.", "path");
Marshal.ThrowExceptionForHR(result);
return new Uri(buffer.ToString());
}
[DllImport("shlwapi.dll", CharSet=CharSet.Auto, SetLastError=true)]
static extern int UrlCreateFromPath(string path, StringBuilder url, ref int urlLength, int reserved);
In case the path starts with with a special prefix, it gets removed. Although the documentation doesn't mention it, the function outputs the length of the URL even if the buffer is smaller, so I first obtain the length and then allocate the buffer.
Some very interesting observation I had is that while "\\device\path" is correctly transformed to "file://device/path", specifically "\\localhost\path" is transformed to just "file:///path".
The WinApi function managed to encode special characters, but leaves Unicode-specific characters unencoded, unlike the Uri construtor. In that case, AbsoluteUri contains the properly encoded URL, while OriginalString can be used to retain the Unicode characters.
strSearch in this case is probably null (not simply empty).
Try using
String.IsNullOrEmpty(strSearch)
if you are just trying to determine if the string doesn't have any contents.
No need to use BufferedImage, as you already have the image file in a byte array

FileOutputStream fos = new FileOutputStream(new File("c:/decode/abc.bmp"));
fos.write(dearr);
fos.close();
The PostgreSQL manual indicates that this means the transaction is open (inside BEGIN) and idle. It's most likely a user connected using the monitor who is thinking or typing. I have plenty of those on my system, too.
If you're using Slony for replication, however, the Slony-I FAQ suggests idle in transaction
may mean that the network connection was terminated abruptly. Check out the discussion in that FAQ for more details.

One way would be to make a list of lists, with each sub-list in the new list containing a word and a count:
list1 = [] #this is your original list of words
list2 = [] #this is a new list
for word in list1:
if word in list2:
list2.index(word)[1] += 1
else:
list2.append([word,0])
Or, more efficiently:
for word in list1:
try:
list2.index(word)[1] += 1
except:
list2.append([word,0])
This would be less efficient than using a dictionary, but it uses more basic concepts.

My problem was that I was getting the data back in a string
which was not in a proper JSON format, which I was then trying to parse it. simple example: JSON.parse('{hello there}')
will give an error at h. In my case the callback url was returning an unnecessary character before the objects: employee_names([{"name":....
and was getting error at e at 0. My callback URL itself had an issue which when fixed, returned only objects.
Instead of wading through the description of all the options, you can jump to 3.4.3 Short Options Cross Reference
under the info tar
command.
x
means --extract
. v
means --verbose
. f
means --file
. z
means --gzip
. You can combine one-letter arguments together, and f
takes an argument, the filename. There is something you have to watch out for:
Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below). When short options are clumped as a set, use one (single) dash for them all, e.g., ''tar' -cvf'. Only the last option in such a set is allowed to have an argument(1).
This old way of writing 'tar' options can surprise even experienced users. For example, the two commands:tar cfz archive.tar.gz file tar -cfz archive.tar.gz file
are quite different. The first example uses 'archive.tar.gz' as the value for option 'f' and recognizes the option 'z'. The second example, however, uses 'z' as the value for option 'f' -- probably not what was intended.
Patrick is correct, both in the use of the xsl:if
, and in the syntax for checking for the existence of a node. However, as Patrick's response implies, there is no xsl equivalent to if-then-else, so if you are looking for something more like an if-then-else, you're normally better off using xsl:choose
and xsl:otherwise
. So, Patrick's example syntax will work, but this is an alternative:
<xsl:choose>
<xsl:when test="/html/body">body node exists</xsl:when>
<xsl:otherwise>body node missing</xsl:otherwise>
</xsl:choose>
Check out strptime in the time module. It is the inverse of strftime.

tm_hour=13, tm_min=33, tm_sec=0,
tm_wday=2, tm_yday=152, tm_isdst=-1)
timestamp = time.mktime(my_time)
# convert time object to datetime
from datetime import datetime
my_datetime = datetime.fromtimestamp(timestamp)
# convert time object to date

What do you want to do with file? Only writing to it or both read and write?
'w'
, 'a'
will allow write and will create the file if it doesn't exist.
If you need to read from a file, the file has to be exist before open it. You can test its existence before opening it or use a try/except.

In the most shared hosts you can't set it.
On a VPS or dedicated server, you can set it, but everything has its price.
On shared hosts, in general you receive a Linux account, something such as /home/(your username)/, and the equivalent of /var/www/html turns to /home/(your username)/public_html/ (or something similar, such as /home/(your username)/www)
If you're accessing your account via FTP, you automatically has accessing the your */home/(your username)/ folder, just find the www or public_html and put your site in it.
If you're using absolute path in the code, bad news, you need to refactor it to use relative paths in the code, at least in a shared host.
Your code is valid (with one exception). It is required to have code between BEGIN and END.

A 32 bit floating point number has 23 + 1 bits of mantissa and an 8 bit exponent (-126 to 127 is used though) so the largest number you can represent is:
(1 + 1 / 2 + ... 1 / (2 ^ 23)) * (2 ^ 127) =
(2 ^ 23 + 2 ^ 23 + .... 1) * (2 ^ (127 - 23)) =
(2 ^ 24 - 1) * (2 ^ 104) ~= 3.4e38
I did not know that even with the "Allow Installation of non-Marked application", I still needed to sign the application.

The terms "background page", "popup", "content script" are still confusing you; I strongly suggest a more in-depth look at the Google Chrome Extensions Documentation.
Regarding your question if content scripts or background pages are the way to go:
Content scripts: Definitely
Content scripts are the only component of an extension that has access to the web-page's DOM.
Background page / Popup: Maybe (probably max. 1 of the two)
You may need to have the content script pass the DOM content to either a background page or the popup for further processing.
Let me repeat that I strongly recommend a more careful study of the available documentation!
That said, here is a sample extension that retrieves the DOM content on StackOverflow pages and sends it to the background page, which in turn prints it in the console:
background.js:
// Regex-pattern to check URLs against.
// It matches URLs like: http[s]://[...]stackoverflow.com[...]
var urlRegex = /^https?:\/\/(?:[^./?#]+\.)?stackoverflow\.com/;
// A function to use as callback
function doStuffWithDom(domContent) {
console.log('I received the following DOM content:\n' + domContent);
}
// When the browser-action button is clicked...
chrome.browserAction.onClicked.addListener(function (tab) {
// ...check the URL of the active tab against our pattern and...
if (urlRegex.test(tab.url)) {
// ...if it matches, send a message specifying a callback too
chrome.tabs.sendMessage(tab.id, {text: 'report_back'}, doStuffWithDom);
}
});
content.js:
// Listen for messages
chrome.runtime.onMessage.addListener(function (msg, sender, sendResponse) {
// If the received message has the expected format...
if (msg.text === 'report_back') {
// Call the specified callback, passing
// the web-page's DOM content as argument
sendResponse(document.all[0].outerHTML);
}
});

Otherwise, when $1

From the Java JDBC tutorial:
In previous versions of JDBC, to obtain a connection, you first had to initialize your JDBC driver by calling the method
Class.forName
. Any JDBC 4.0 drivers that are found in your class path are automatically loaded. (However, you must manually load any drivers prior to JDBC 4.0 with the methodClass.forName
.)
So, if you're using the Oracle 11g (11.1) driver with Java 1.6, you don't need to call Class.forName
. Otherwise, you need to call it to initialise the driver.
Never use AsynTask to perform network request or whatever that need to be persisted. Async Task are strongly tied to your activity and if the user change the orientation of the screen since the App is re created the AsyncTask will be stopped.
I suggest you to use Service pattern with Intent Service and ResultReceiver. Take a look to RESTDroid. It's a library that allows you to perform any kind of REST request asynchronously and notify your UI with Request Listeners implementing the Virgil Dobjanschi's service pattern.

SELECT t.ID ,

drop table if exists foo;
create table foo
(
id int unsigned not null auto_increment primary key,
val smallint unsigned not null default 0
)

drop procedure if exists load_foo_test_data;
delimiter #
create procedure load_foo_test_data()
begin
declare v_max int unsigned default 1000;
declare v_counter int unsigned default 0;
truncate table foo;
start transaction;
while v_counter < v_max do
insert into foo (val) values ( floor(0 + (rand() * 65535)) );
set v_counter=v_counter+1;
end while;
commit;
end #
delimiter ;
call load_foo_test_data();
select * from foo order by id;
You need to escape:

NOLOCK makes most SELECT statements faster, because of the lack of shared locks. Also, the lack of issuance of the locks means that writers will not be impeded by your SELECT.
NOLOCK is functionally equivalent to an isolation level of READ UNCOMMITTED. The main difference is that you can use NOLOCK on some tables but not others, if you choose. If you plan to use NOLOCK on all tables in a complex query, then using SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED is easier, because you don't have to apply the hint to every table.
Here is information about all of the isolation levels at your disposal, as well as table hints.
It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:
When location matches the last part of the directive’s value: it is better to use the root directive instead:
which would yield:
server {
listen 8080;
server_name www.mysite.com mysite.com;
error_log /home/www-data/logs/nginx_www.error.log;
error_page 404 /404.html;
location /public/doc/ {
autoindex on;
root /home/www-data/mysite;
}
location = /404.html {
root /home/www-data/mysite/static/html;
}
}
I believe, you need to capture this
.
A semaphore is a signaling mechanism used to coordinate between threads. Example: One thread is downloading files from the internet and another thread is analyzing the files. This is a classic producer/consumer scenario. The producer calls signal()
on the semaphore when a file is downloaded. The consumer calls wait()
on the same semaphore in order to be blocked until the signal indicates a file is ready. If the semaphore is already signaled when the consumer calls wait, the call does not block. Multiple threads can wait on a semaphore, but each signal will only unblock a single thread.
A counting semaphore keeps track of the number of signals. E.g. if the producer signals three times in a row, wait()
can be called three times without blocking. A binary semaphore does not count but just have the "waiting" and "signalled" states.
A mutex (mutual exclusion lock) is a lock which is owned by a single thread. Only the thread which have acquired the lock can realease it again. Other threads which try to acquire the lock will be blocked until the current owner thread releases it. A mutex lock does not in itself lock anything - it is really just a flag. But code can check for ownership of a mutex lock to ensure that only one thread at a time can access some object or resource.
A monitor is a higher-level construct which uses an underlying mutex lock to ensure thread-safe access to some object. Unfortunately the word "monitor" is used in a few different meanings depending on context and platform and context, but in Java for example, a monitor is a mutex lock which is implicitly associated with an object, and which can be invoked with the synchronized
keyword. The synchronized
keyword can be applied to a class, method or block and ensures only one thread can execute the code at a time.
Have you converted your data from string to JavaScript object?
You can do it with data = eval('(' + string_data + ')');
or, which is safer, data = JSON.parse(string_data);
but later will only works in FF 3.5 or if you include json2.js
jQuery since 1.4.1 also have function for that, $.parseJSON()
.
But actually, $.getJSON()
should give you already parsed json object, so you should just check everything thoroughly, there is little mistake buried somewhere, like you might have forgotten to quote something in json, or one of the brackets is missing.
There's no need to start idle transactions on the master. In postgresql-9.1 the most direct way to solve this problem is by setting
hot_standby_feedback = on
This will make the master aware of long-running queries. From the docs:
The first option is to set the parameter hot_standby_feedback, which prevents VACUUM from removing recently-dead rows and so cleanup conflicts do not occur.
Why isn't this the default? This parameter was added after the initial implementation and it's the only way that a standby can affect a master.
Just found this old thread, looking for some kind of escape sequence to blank the actual line.
It's quite funny no one came to the idea (or I have missed it) that printf returns the number of characters written. So just print '\r' + as many blank characters as printf returned and you will exactly blank the previuosly written text.
int BlankBytes(int Bytes)
{
char strBlankStr[16];
sprintf(strBlankStr, "\r%%%is\r", Bytes);
printf(strBlankStr,"");
return 0;
}
int main(void)
{
int iBytesWritten;
double lfSomeDouble = 150.0;
iBytesWritten = printf("test text %lf", lfSomeDouble);
BlankBytes(iBytesWritten);
return 0;
}
As I cant use VT100, it seems I have to stick with that solution
I found this question and none of the solutions here worked for me. I found another solution that got rid of the gaps below images in Chrome. I had to add line-height:0;
to the img selector in my CSS and the gaps below images went away.
Crazy that this problem persists in browsers in 2013.

I tried a couple of solution but I thing easy way like this (you are in the local folder):
#!/bin/bash
git fetch
var_local=`cat .git/refs/heads/master`
var_remote=`git log origin/master -1 | head -n1 | cut -d" " -f2`
if [ "$var_remote" = "$var_local" ]; then
echo "Strings are equal." #1
else
echo "Strings are not equal." #0 if you want
fi
Then you did compare local git and remote git last commit number....
ViewTreeObserver
and onWindowFocusChanged()
are not so necessary at all.
If you inflate the TextView
as layout and/or put some content in it and set LayoutParams
then you can use getMeasuredHeight()
and getMeasuredWidth()
.
BUT you have to be careful with LinearLayouts
(maybe also other ViewGroups
). The issue there is, that you can get the width and height after onWindowFocusChanged()
but if you try to add some views in it, then you can't get that information until everything have been drawn. I was trying to add multiple TextViews
to LinearLayouts
to mimic a FlowLayout
(wrapping style) and so couldn't use Listeners
. Once the process is started, it should continue synchronously. So in such case, you might want to keep the width in a variable to use it later, as during adding views to layout, you might need it.
If you are using a template engine like Asp.net Razor Engine or Angular, I think you must re-generate your page and split the page in several pages and then you can freely markup each page and put header and footer on theme. one example could be as bellow:

I wrote a program that demonstrates how to separate the digits of an integer using a more simple and understandable approach that does not involve arrays, recursions, and all that fancy schmancy. Here is my code:
int year = sc.nextInt(), temp = year, count = 0;
while (temp>0)
{
count++;
temp = temp / 10;
}
double num = Math.pow(10, count-1);
int i = (int)num;
for (;i>0;i/=10)
{
System.out.println(year/i%10);
}
Suppose your input is the integer 123
, the resulting output will be as follows:
1
2
3
Firstly, in histories_T, you are referencing table T_customer (should be T_customers) and secondly, you are missing the FOREIGN KEY clause that REFERENCES orders; which is not being created (or dropped) with the code you provided.
There may be additional errors as well, and I admit Oracle has never been very good at describing the cause of errors - "Mutating Tables" is a case in point.
Let me know if there additional problems you are missing.

Sounds like you're trying to execute the PHP code directly in your shell. Your shell doesn't speak PHP, so it interprets your PHP code as though it's in your shell's native language, as though you had literally run <?php
at the command line.
Shell scripts usually start with a "shebang" line that tells the shell what program to use to interpret the file. Begin your file like this:
#!/usr/bin/env php
<?php
//Connection
function connection () {
Besides that, the string you're passing to exec
doesn't make any sense. It starts with a slash all by itself, it uses too many periods in the path, and it has a stray right parenthesis.
Copy the contents of the command string and paste them at your command line. If it doesn't run there, then exec
probably won't be able to run it, either.
Another option is to change the command you execute. Instead of running the script directly, run php
and pass your script as an argument. Then you shouldn't need the shebang line.
exec('php name.php');
The default value is indeed false.
However you can't use a local variable is it's not been assigned first.
You can use the default keyword to verify:
bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }
Consider if instead it was:
class RectangularRoom(object):
def __init__(self, width, height):
pass
def cleanTileAtPosition(self, pos):
pass
def isTileCleaned(self, m, n):
pass
and you subclass and forget to tell it how to isTileCleaned()
or, perhaps more likely, typo it as isTileCLeaned()
. Then in your code, you'll get a None
when you call it.
None
valid output? Who knows. raise NotImplmentedError
forces you to implement it, as it will throw an exception when you try to run it until you do so. This removes a lot of silent errors. It's similar to why a bare except is almost never a good idea: because people make mistakes and this makes sure they aren't swept under the rug.
Note: Using an abstract base class, as other answers have mentioned, is better still, as then the errors are frontloaded and the program won't run until you implement them (with NotImplementedError, it will only throw an exception if actually called).
As of now (06/07/2018), an easy approach would be running az account show in the Azure Cloud Shell (requires a Storage Account) in the Azure Portal.
--- Command ---
az account show
--- Command Output ---
{
"environmentName": "AzureCloud",
"id": "{Subscription Id (GUID)}",
"isDefault": true,
"name": "{Subscription Name}",
"state": "Enabled",
"tenantId": "{Tenant Id (GUID)}",
"user": {
"cloudShellID": true,
"name": "{User email}",
"type": "user"
}
}

you have to rename the column to an other name because TABLE
is reserved by Oracle.
You can see all reserved words of Oracle in the oracle view V$RESERVED_WORDS
.
If you need to see the output of the execute, use CALL
together with or instead of START
.
Example:
CALL "C:\Program Files\Certain Directory\file.exe" -param
PAUSE
This will run the file.exe and print back whatever it outputs, in the same command window. Remember the PAUSE
after the call or else the window may close instantly.
This is what helped me:
Create a new branch with the existing one. Let's call the existing one branch_old
and new as branch_new
.
Reset branch_new
to a stable state, when you did not have any problem commit at all.
For example, to put it at your local master's level do the following:
git reset —hard master git push —force origin
cherry-pick
the commits from branch_old
into branch_new
git push
I suposse this is the output you need:
title,intro,tagline
2.9,Gardena,CA
It can be done with this changes to your code:
import csv
import itertools
with open('log.txt', 'r') as in_file:
lines = in_file.read().splitlines()
stripped = [line.replace(","," ").split() for line in lines]
grouped = itertools.izip(*[stripped]*1)
with open('log.csv', 'w') as out_file:
writer = csv.writer(out_file)
writer.writerow(('title', 'intro', 'tagline'))
for group in grouped:
writer.writerows(group)
If you want to do this in VBA, then this is a shorter method:
Sub FillBlanksWithNull()
'This macro will fill all "blank" cells with the text "Null"
'When no range is selected, it starts at A1 until the last used row/column
'When a range is selected prior, only the blank cell in the range will be used.
On Error GoTo ErrHandler:
Selection.SpecialCells(xlCellTypeBlanks).FormulaR1C1 = "Null"
Exit Sub
ErrHandler:
MsgBox "No blank cells found", vbDefaultButton1, Error
Resume Next
End Sub

you can use below function if you know the id of the user:
function getUser(id){
var returnValue;
jQuery.ajax({
url: "http://YourSite/_api/Web/GetUserById(" + id + ")",
type: "GET",
headers: { "Accept": "application/json;odata=verbose" },
success: function(data) {
var dataResults = data.d;
alert(dataResults.Title);
}
});
}
or you can try
var listURL = _spPageContextInfo.webAbsoluteUrl + "/_api/web/currentuser";
I think that your foreign key is backwards. Try:
ALTER TABLE 'jobs'
ADD CONSTRAINT `advertisers_ibfk_1` FOREIGN KEY (`advertiser_id`) REFERENCES `advertisers` (`advertiser_id`)
To set the disabled
to false using the name
property of the input:
document.myForm.myInputName.disabled = false;
If your JSON payload contains arrays and nested objects, I would use URLSearchParams
and jQuery's param()
method.
fetch('/somewhere', {
method: 'POST',
body: new URLSearchParams($.param(payload))
})
To your server, this will look like a standard HTML <form>
being POST
ed.
For me this is what I use if adding \n
is not a problem.
fmt.Sprintf("Hello World\nHow are you doing today\nHope all is well with your go\nAnd code")
Else you can use the raw string
multiline := `Hello Brothers and sisters of the Code
The grail needs us.

Very late answer, but I think my answer is more straight forward for specific use cases where users want to simply insert (copy) data from table A into table B:
INSERT INTO table_b (col1, col2, col3, col4, col5, col6)
SELECT col1, 'str_val', int_val, col4, col5, col6
FROM table_a

In a Firebird database the AFTER myOtherColumn
does not work but you can try re-positioning the column using:
ALTER TABLE name ALTER column POSITION new_position
I guess it may work in other cases as well.
Solution:
INSERT INTO `table` (`value1`, `value2`)
SELECT 'stuff for value1', 'stuff for value2' FROM DUAL
WHERE NOT EXISTS (SELECT * FROM `table`
WHERE `value1`='stuff for value1' AND `value2`='stuff for value2' LIMIT 1)
Explanation:
The innermost query
SELECT * FROM `table`
WHERE `value1`='stuff for value1' AND `value2`='stuff for value2' LIMIT 1
used as the WHERE NOT EXISTS
-condition detects if there already exists a row with the data to be inserted. After one row of this kind is found, the query may stop, hence the LIMIT 1
(micro-optimization, may be omitted).
The intermediate query
SELECT 'stuff for value1', 'stuff for value2' FROM DUAL
represents the values to be inserted. DUAL
refers to a special one row, one column table present by default in all Oracle databases (see https://en.wikipedia.org/wiki/DUAL_table). On a MySQL-Server version 5.7.26 I got a valid query when omitting FROM DUAL
, but older versions (like 5.5.60) seem to require the FROM
information. By using WHERE NOT EXISTS
the intermediate query returns an empty result set if the innermost query found matching data.
The outer query
INSERT INTO `table` (`value1`, `value2`)
inserts the data, if any is returned by the intermediate query.
The more powerful (and 100% fluid) Bootstrap 3 grid now comes in 3 sizes. Tiny (for smartphones .col-), Small (for tablets .col-sm-) and Large (for laptops/desktops .col-lg-*). The 3 grid sizes enable you to control grid behavior on different devices (desktop, tablet, smartphone, etc..).
Unlike 2.x, Bootstrap 3 does not provide a fixed (pixel-based) grid. While a fixed-width layout can still be acheived using a simple custom wrapper, there is now only one percentage-based (fluid) grid. The .container and .row classes are now fluid by default, so don't use .row-fluid or .container-fluid anymore in your 3.x markup.

In this case, there are two videos because the live stream contains two cameras. From here, we need to get the HLS URL for a specific stream. Use -f
to pass in the format you would like to watch, and -g
to get that stream's URL:

You can use SQLAlchemy's or_
function to search in more than one column (the underscore is necessary to distinguish it from Python's own or
).
Here's an example:
from sqlalchemy import or_
query = meta.Session.query(User).filter(or_(User.firstname.like(searchVar),
User.lastname.like(searchVar)))
df --output=avail -B 1 "$PWD" |tail -n 1
you get size in bytes this way.
Alternatives to Native Support of Java Operator Overloading
Since Java doesn't have operator overloading, here are some alternatives you can look into:
If anyone is aware of others, please comment, and I will add it to this list.
It may be usefull.
All values in array represent what you want to be (null, undefined or another things) and you search what you want in it.
var variablesWhatILookFor = [null, undefined, ''];
variablesWhatILookFor.indexOf(document.DocumentNumberLabel) > -1
When you use a decorator, you're replacing one function with another. In other words, if you have a decorator
def logged(func):
def with_logging(*args, **kwargs):
print(func.__name__ + " was called")
return func(*args, **kwargs)
return with_logging
then when you say
@logged
def f(x):
"""does some math"""
return x + x * x
it's exactly the same as saying
def f(x):
"""does some math"""
return x + x * x
f = logged(f)
and your function f
is replaced with the function with_logging
. Unfortunately, this means that if you then say
print(f.__name__)
it will print with_logging
because that's the name of your new function. In fact, if you look at the docstring for f
, it will be blank because with_logging
has no docstring, and so the docstring you wrote won't be there anymore. Also, if you look at the pydoc result for that function, it won't be listed as taking one argument x
; instead it'll be listed as taking *args
and **kwargs
because that's what with_logging takes.
If using a decorator always meant losing this information about a function, it would be a serious problem. That's why we have functools.wraps
. This takes a function used in a decorator and adds the functionality of copying over the function name, docstring, arguments list, etc. And since wraps
is itself a decorator, the following code does the correct thing:
from functools import wraps
def logged(func):
@wraps(func)
def with_logging(*args, **kwargs):
print(func.__name__ + " was called")
return func(*args, **kwargs)
return with_logging
@logged
def f(x):
"""does some math"""
return x + x * x
print(f.__name__) # prints 'f'
print(f.__doc__) # prints 'does some math'
Here's a mixin that you can mix into any model class which gives each instance an update
method:
class UpdateMixin(object):
def update(self, **kwargs):
if self._state.adding:
raise self.DoesNotExist
for field, value in kwargs.items():
setattr(self, field, value)
self.save(update_fields=kwargs.keys())
The self._state.adding
check checks to see if the model is saved to the database, and if not, raises an error.
(Note: This update
method is for when you want to update a model and you know the instance is already saved to the database, directly answering the original question. The built-in update_or_create
method featured in Platinum Azure's answer already covers the other use-case.)
You would use it like this (after mixing this into your user model):
user = request.user
user.update(favorite_food="ramen")
Besides having a nicer API, another advantage to this approach is that it calls the pre_save
and post_save
hooks, while still avoiding atomicity issues if another process is updating the same model.

You also have to modify the minimum size of the data and log files. DBCC SHRINKDATABASE will shrink the data inside the files you already have allocated. To shrink a file to a size smaller than its minimum size, use DBCC SHRINKFILE and specify the new size.
Also, do not forget to mention that Google's V8 is VERY fast. It actually converts the JavaScript code to machine code with the matched performance of compiled binary. So along with all the other great things, it's INSANELY fast.
Maybe this would work:
Remove the double backslashes from the parameter of the split method:
split = docStr.split("\n");
I had the same issue, but the other answers only supplied one part of the solution.
The solution is two fold:
Remove the 64bit from the Register.
or
Register it as 32bit:
C:\Windows\SysWOW64\regsvr32 <file.dll>
Registering it as 32bit without removing the 64bit registration does not resolve my issue.

No not directly. What you can do though is quickly exit insert mode for a single normal mode operation with Ctrl-O and then paste from there which will end by putting you back in insert mode.

EDIT: Interesting. It does appear that there is a way as several other people have listed.
You can't modify SQLite tables in any significant way after they have been created. The accepted suggested solution is to create a new table with the correct requirements and copy your data into it, then drop the old table.
here is the official documentation about this: http://sqlite.org/faq.html#q11
C++ can print whatever you want if you program it to do so. You'll have to go through the array yourself printing each element.
As it was already mentioned here Callable is relatively new interface and it was introduced as a part of concurrency package. Both Callable and Runnable can be used with executors. Class Thread (that implements Runnable itself) supports Runnable only.
You can still use Runnable with executors. The advantage of Callable that you can send it to executor and immediately get back Future result that will be updated when the execution is finished. The same may be implemented with Runnable, but in this case you have to manage the results yourself. For example you can create results queue that will hold all results. Other thread can wait on this queue and deal with results that arrive.

Seems there is some demand to be able to access this statically.
How can I get such thing in static methods in non-spring-managed classes? – Aetherus
It's a hack, but you can write your own class to expose it. You must be careful to ensure that nothing will call SpringContext.getEnvironment()
before all beans have been created, since there is no guarantee when this component will be instantiated.
@Component
public class SpringContext
{
private static Environment environment;
public SpringContext(Environment environment) {
SpringContext.environment = environment;
}
public static Environment getEnvironment() {
if (environment == null) {
throw new RuntimeException("Environment has not been set yet");
}
return environment;
}
}
java [any other JVM options you need to give it] -jar foo.jar
You can access component one's method from component two..
componentOne
ngOnInit() {}
public testCall(){
alert("I am here..");
}
componentTwo
import { oneComponent } from '../one.component';
@Component({
providers:[oneComponent ],
selector: 'app-two',
templateUrl: ...
}
constructor(private comp: oneComponent ) { }
public callMe(): void {
this.comp.testCall();
}
componentTwo html file
<button (click)="callMe()">click</button>
mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/…
to get it rewritten to a corresponding /folder1/…
.
Try this:
RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1
This rule will rewrite every request that starts with the URI path /apple/…
internally to /folder1/…
.
Edit As you are actually looking for the other way round:
RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]
This rule is designed to work together with the other rule above. Requests of /folder1/…
will be redirected externally to /apple/…
and requests of /apple/…
will then be rewritten internally back to /folder1/…
.
You can try like this.
Create Class with element id.
public Enum MyEnum {
THIS(5),
THAT(16),
THE_OTHER(35);
private int id; // Could be other data type besides int
private MyEnum(int id) {
this.id = id;
}
public static MyEnum fromId(int id) {
for (MyEnum type : values()) {
if (type.getId() == id) {
return type;
}
}
return null;
}
}
Now Fetch this Enum using id as int.
MyEnum myEnum = MyEnum.fromId(5);
Here's some more detailed information on what Client, Resource, and Session are all about.
Client:
Here's an example of client-level access to an S3 bucket's objects (at most 1000**):
import boto3
client = boto3.client('s3')
response = client.list_objects_v2(Bucket='mybucket')
for content in response['Contents']:
obj_dict = client.get_object(Bucket='mybucket', Key=content['Key'])
print(content['Key'], obj_dict['LastModified'])
** you would have to use a paginator, or implement your own loop, calling list_objects() repeatedly with a continuation marker if there were more than 1000.
Resource:
Here's the equivalent example using resource-level access to an S3 bucket's objects (all):
import boto3
s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')
for obj in bucket.objects.all():
print(obj.key, obj.last_modified)
Note that in this case you do not have to make a second API call to get the objects; they're available to you as a collection on the bucket. These collections of subresources are lazily-loaded.
You can see that the Resource
version of the code is much simpler, more compact, and has more capability (it does pagination for you). The Client
version of the code would actually be more complicated than shown above if you wanted to include pagination.
Session:
A useful resource to learn more about these boto3 concepts is the introductory re:Invent video.
0 * * * * cd folder_containing_exe && ./exe_name
should work unless there is something else that needs to be setup for the program to run.
Leaving this here for myself,
If I get this error, I probably used const char*
when I should be using char* const
.
This makes the pointer constant, and not the contents of the string.
const char* const
makes it so the value and the pointer is constant also.
I had this problem after upgrading to macOS Catalina.
The issue is resolved as follows:
1. Find git location from the terminal:
which git
2. Add the location of git in settings file with your location:
settings.json
"git.path": "/usr/local/bin/git",
Depending on your platform, the user settings file (settings.json) is located here:
Windows
%APPDATA%\Code\User\settings.json
macOS
$HOME/Library/Application Support/Code/User/settings.json
Linux
$HOME/.config/Code/User/settings.json
This is much easier in pandas now with drop_duplicates and the keep parameter.
import pandas as pd
df = pd.DataFrame({"A":["foo", "foo", "foo", "bar"], "B":[0,1,1,1], "C":["A","A","B","A"]})
df.drop_duplicates(subset=['A', 'C'], keep=False)
From one of my other posts, getting a unixtimestamp:
$unixTimestamp = time();
Converting to mysql datetime format:
$mysqlTimestamp = date("Y-m-d H:i:s", $unixTimestamp);
Getting some mysql timestamp:
$mysqlTimestamp = '2013-01-10 12:13:37';
Converting it to a unixtimestamp:
$unixTimestamp = strtotime('2010-05-17 19:13:37');
...comparing it with one or a range of times, to see if the user entered a realistic time:
if($unixTimestamp > strtotime("1999-12-15") && $unixTimestamp < strtotime("2025-12-15"))
{...}
Unix timestamps are safer too. You can do the following to check if a url passed variable is valid, before checking (for example) the previous range check:
if(ctype_digit($_GET["UpdateTimestamp"]))
{...}
You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.
If the above problem is faced at Facebook login then you can use the below code in a parent activity of your fragment like:
Fragment fragment = getFragmentManager().findFragmentById(android.R.id.tabcontent);
fragment.onActivityResult(requestCode, resultCode, data);
Or:
Fragment fragment = getFragmentManager().findFragmentById("fragment id here");
fragment.onActivityResult(requestCode, resultCode, data);
And add the below call in your fragment...
callbackManager.onActivityResult(requestCode, resultCode, data);
To answer the question. stringstream
basically allows you to treat a string
object like a stream
, and use all stream
functions and operators on it.
I saw it used mainly for the formatted output/input goodness.
One good example would be c++
implementation of converting number to stream object.
Possible example:
template <class T>
string num2str(const T& num, unsigned int prec = 12) {
string ret;
stringstream ss;
ios_base::fmtflags ff = ss.flags();
ff |= ios_base::floatfield;
ff |= ios_base::fixed;
ss.flags(ff);
ss.precision(prec);
ss << num;
ret = ss.str();
return ret;
};
Maybe it's a bit complicated but it is quite complex. You create stringstream
object ss
, modify its flags, put a number into it with operator<<
, and extract it via str()
. I guess that operator>>
could be used.
Also in this example the string
buffer is hidden and not used explicitly. But it would be too long of a post to write about every possible aspect and use-case.
Note: I probably stole it from someone on SO and refined, but I don't have original author noted.

This is how I do it in my code.
WebDriverWait wait = new WebDriverWait(webDriver, timeoutInSeconds);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id<locator>));
or
wait.until(ExpectedConditions.elementToBeClickable(By.id<locator>));
to be precise.

The Problem is with your code formatting,
inorder to use strtotime()
You should replace '06/Oct/2011:19:00:02'
with 06/10/2011 19:00:02
and date('d/M/Y:H:i:s', $date);
with date('d/M/Y H:i:s', $date);
. Note the spaces in between.
So the final code looks like this
$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);
i have faced the same problem. the following solution have worked for me.
FrameLayout glFrame=(FrameLayout) findViewById(R.id.animatedView);
glFrame.addView(yourView);
glFrame.bringToFront();
glFrame.invalidate();
2nd solution is by using xml adding this attribute to the view xml
android:translationZ=""
The XML configuration of Spring is composed of Beans and Beans are basically classes. They're just POJOs that we use inside of our ApplicationContext. Defining Beans can be thought of as replacing the keyword new. So wherever you are using the keyword new in your application something like:
MyRepository myRepository =new MyRepository ();
Where you're using that keyword new that's somewhere you can look at removing that configuration and placing it into an XML file. So we will code like this:
<bean name="myRepository "
class="com.demo.repository.MyRepository " />
Now we can simply use Setter Injection/ Constructor Injection. I'm using Setter Injection.
public class MyServiceImpl implements MyService {
private MyRepository myRepository;
public void setMyRepository(MyRepository myRepository)
{
this.myRepository = myRepository ;
}
public List<Customer> findAll() {
return myRepository.findAll();
}
}
I was needed to solve absolutely the same task. I have divided visually the table using different background colors for different parts. Googling the Internet I've found this page https://support.microsoft.com/kb/2815384. Unfortunately it doesn't solve the issue because ColorIndex refers to some unpredictable value, so if some cells have nuances of one color (for example different values of brightness of the color), the suggested function counts them. The solution below is my fix:
Function CountBgColor(range As range, criteria As range) As Long
Dim cell As range
Dim color As Long
color = criteria.Interior.color
For Each cell In range
If cell.Interior.color = color Then
CountBgColor = CountBgColor + 1
End If
Next cell
End Function
It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:
[...] when looping through the
Iterable
value list, each Object instance is re-used, so it only keeps one instance around at a given time.
I required the same functionality as requested in the main question. As I was not allowed to use any 3rd party libraries, I have created my own solution basing on @Archimedes Trajano solution.

It compares two XML strings and takes care of any mismatching namespace mappings by translating them to unique values in both input strings.
Can be fine tuned i.e. in case of translation of namespaces. But for my requirements just does the job.
You're looking for the onclose event.
see: https://developer.mozilla.org/en/DOM/window.onclose
note that not all browsers support this (for example firefox 2)
In pure Python:
def get_param_from_url(url, param_name):
return [i.split("=")[-1] for i in url.split("?", 1)[-1].split("&") if i.startswith(param_name + "=")][0]
If you want to stop process you can kill it manually from task manager onother side if you want to stop running query in DBMS you can stop as given here for ms sqlserver T-SQL STOP or ABORT command in SQL Server Hope it helps you
It happened to me with a node app I was developing on a Debian based distro. First, a simple restart solved it, but it happened again on another app.
Since it's related with the number of watchers that inotify uses to monitors files and look for changes in a directory, you have to set a higher number as limit:
I was able to solve it from the answer posted here (thanks to him!)
So, I ran:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
Read more about what’s happening at https://github.com/guard/listen/wiki/Increasing-the-amount-of-inotify-watchers#the-technical-details
Hope it helps!
Your problem is not actually specific to ejs.
2 things to note here
style.css is an external css file. So you dont need style tags inside that file. It should only contain the css.
In your express app, you have to mention the public directory from which you are serving the static files. Like css/js/image
it can be done by
app.use(express.static(__dirname + '/public'));
assuming you put the css files in public folder from in your app root. now you have to refer to the css files in your tamplate files, like
<link href="/css/style.css" rel="stylesheet" type="text/css">
Here i assume you have put the css file in css folder inside your public folder.
So folder structure would be
.
./app.js
./public
/css
/style.css
You could also use boost, which defines important math constants with maximum accuracy for the requested type (i.e. float vs double).
const double pi = boost::math::constants::pi<double>();
Check out the boost documentation for more examples.
Is there any command in Linux through which i can know if the process is in hang state.
There is no command, but once I had to do a very dumb hack to accomplish something similar. I wrote a Perl script which periodically (every 30 seconds in my case):
ps
to find list of PIDs of the watched processes (along with exec time, etc)gdb
attaching to the process using its PID, dumping stack trace from it using thread apply all where
, detaching from the processBut that was very very very very crude hack, done to reach an about-to-be-missed deadline and it was removed a few days later, after a fix for the buggy application was finally installed.
Otherwise, as all other responders absolutely correctly commented, there is no way to find whether the process hung or not: simply because the hang might occur for way to many reasons, often bound to the application logic.
The only way is for application itself being capable of indicating whether it is alive or not. Simplest way might be for example a periodic log message "I'm alive".
Another thing to try is
Tools -> Options -> search for IIS -> tick Use the 64 bit version of IIS Express for web sites and projects.
Haven't tried it yet, but Configgy looks promising for both configuration and logging:
If don't store it locally and use the link that they provide you might have an improved performance.The client might have the scripts already cached in some cases. As for the case of jQueryUI i would recommend not loading it until necessary. They are both minimized, but you can fire up the console and look at the network tab and see how long it takes for it to load, once it is initially downloaded it will be cached so you shouldn't worry afterwards.My conclusion would be yes use them both but use a CDN
Can use a spread syntax, something like this:
inputChangeHandler : function (event) {
this.setState( {
...this.state,
[event.target.id]: event.target.value
} );
},
X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
Variable1 Variable2
1 11 2
2 14 3
3 12 1
4 15 4
> X[X$Variable1!=11 & X$Variable1!=12, ]
Variable1 Variable2
2 14 3
4 15 4
> X[ ! X$Variable1 %in% c(11,12), ]
Variable1 Variable2
2 14 3
4 15 4
You can functionalize this however you like.
The entire new
expression is an object reference, so methods can be invoked on it:
public class A {
public static void main(String[] arg)
{
new Thread()
{
public void run() {
System.out.println("blah");
}
}.start();
}
}
